Denny <joeldenny (a] joeldenny.org> 100 101 doc: clean up references to `Locations Overview'. 102 * doc/bison.texinfo (Locations Overview): Rename node to... 103 (Locations): ... this, which is its section name. Update menus to 104 match that and not to use the title `Tracking Locations', which is 105 a different section. 106 107 2011-05-29 Joel E. Denny <joeldenny (a] joeldenny.org> 108 109 doc: clean up references to `Tracking Locations'. 110 * doc/bison.texinfo (Locations): Rename node to... 111 (Tracking Locations): ... this, which is its section name, and 112 update all cross references. The trouble is that there is another 113 node about locations. Its section name is `Locations', which was 114 easily confused with the node name of this node. Moreover, its 115 node name is `Locations Overview', which was mistakenly used to 116 label some cross references to this node. 117 118 2011-05-29 Joel E. Denny <joeldenny (a] joeldenny.org> 119 120 doc: clean up `Named References' a little. 121 * doc/bison.texinfo (Named References): Rename section to match 122 the node name, and update all cross references. Don't use the 123 acronyms RHS and LHS given that we don't expand them anywhere in 124 the manual. Try to use @samp and @code properly. Mention that 125 named references are experimental as we've already stated in NEWS. 126 (Destructor Decl): Expand the only remaining use of RHS or LHS. 127 128 2011-05-29 Joel E. Denny <joeldenny (a] joeldenny.org> 129 130 doc: motivate named references. 131 Suggested by Hans Aberg at 132 <http://lists.gnu.org/archive/html/bug-bison/2011-05/msg00008.html>. 133 * doc/bison.texinfo (Named References): Explain briefly how 134 they're better than the traditional positional references. 135 136 2011-05-29 Joel E. Denny <joeldenny (a] joeldenny.org> 137 138 doc: discuss named references after locations. 139 Reported by Hans Aberg at 140 <http://lists.gnu.org/archive/html/bug-bison/2011-05/msg00008.html>. 141 * NEWS (2.5.1): Document. 142 * doc/bison.texinfo (Named References): Because it discusses 143 locations in addition to semantic values, move this subsection out 144 of the section `Defining Language Semantics', where locations have 145 not yet been introduced, to be a new section after the following 146 section, `Tracking Locations'. 147 148 2011-05-29 Joel E. Denny <joeldenny (a] joeldenny.org> 149 150 Prepare for the possibility of a 2.5.1 release. 151 * NEWS (2.5.1): New heading. 152 153 2011-05-14 Joel E. Denny <joeldenny (a] joeldenny.org> 154 155 Version 2.5. 156 * NEWS (2.5): Set date. 157 158 2011-05-14 Joel E. Denny <joeldenny (a] joeldenny.org> 159 160 Don't use IF_LINT in Bison sources. 161 It creates unnecessary differences between the sources that Bison 162 maintainers build and test (given that maintainers normally 163 configure with --enable-gcc-warnings) and the sources that Bison 164 users build. Instead, use PACIFY_CC, which doesn't. This change 165 fixes compiler warnings reported by Tys Lefering at 166 <http://lists.gnu.org/archive/html/bison-patches/2011-05/msg00004.html>. 167 * configure.ac: Don't AC_DEFINE lint regardless of the configure 168 options. This change affects imported gnulib sources, where 169 IF_LINT still appears and depends on lint. 170 * src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with 171 PACIFY_CC. 172 * src/system.h (IF_LINT): Remove cpp macro. 173 (PACIFY_CC): New cpp macro. 174 175 2011-05-01 Joel E. Denny <joeldenny (a] joeldenny.org> 176 177 Fix precedence for end token. 178 Since Bison 2.3b, which restored the ability of precedence 179 directives to assign user token numbers, doing so for user token 180 number 0 has produced an assertion failure. 181 * NEWS (2.5): Document fix. 182 * src/symtab.c (symbol_user_token_number_set): In the case of the 183 end token, don't decrement ntokens if it was never incremented. 184 * tests/regression.at (Token number in precedence declaration): 185 Extend. 186 187 2011-05-01 Joel E. Denny <joeldenny (a] joeldenny.org> 188 189 Prepare for 2.5 release. 190 * NEWS (2.5_rc1): Rename back to... 191 (2.5): ... this, and unset date. 192 193 2011-05-01 Joel E. Denny <joeldenny (a] joeldenny.org> 194 195 Version 2.5_rc1. 196 * NEWS (2.5): Rename to... 197 (2.5_rc1): ... this, and set date. 198 199 2011-05-01 Joel E. Denny <joeldenny (a] joeldenny.org> 200 201 Pacify -DGNULIB_POSIXCHECK. 202 * bootstrap.conf (gnulib_modules): Add all modules suggested by 203 -DGNULIB_POSIXCHECK. 204 * src/files.c (file_name_split) 205 * src/getargs.c (getargs) 206 * src/location.c (boundary_set_from_string) 207 * src/output.c (token_definitions_output, output_skeleton) 208 * src/parse-gram.y (prologue_declaration) 209 * src/scan-gram.l (handle_syncline) 210 * src/symtab.c (symbol_new): Use mbschr and mbsrchr instead of 211 strchr and strrchr. In the cases of command-line options, file 212 names, and thus locations, functionality may be improved. In the 213 case of symbol names, there should be no functional difference as 214 all characters are ASCII, so the intended benefit is just warning 215 suppression. 216 217 2011-05-01 Joel E. Denny <joeldenny (a] joeldenny.org> 218 219 * NEWS (2.5): Fix minor typos. 220 221 2011-05-01 Joel E. Denny <joeldenny (a] joeldenny.org> 222 223 doc: clean up quotation style in NEWS. 224 * NEWS (2.5): For multi-character tokens in example grammar rules, 225 use "token" not 'token'. In English, use a consistent quotation 226 style; we might as well follow the precedent seen in info pages: 227 `quote' not "quote". 228 229 2011-04-16 Joel E. Denny <joeldenny (a] joeldenny.org> 230 231 tests: pacify gcc 4.6.0's -Wunused-but-set-variable. 232 Reported by Jim Meyering at 233 <http://lists.gnu.org/archive/html/bug-bison/2011-04/msg00002.html>. 234 * tests/actions.at 235 (Default %printer and %destructor for mid-rule values): Define 236 YYLLOC_DEFAULT so that it uses its Rhs argument. 237 238 2011-04-16 Joel E. Denny <joeldenny (a] joeldenny.org> 239 240 glr.c: omit yyresolveLocations when locations are disabled. 241 This prevents gcc 4.6.0's -Wunused-but-set-variable from warning 242 about yyresolveLocations's local yyrhsloc. When locations are 243 enabled, there's no such warning because YYLLOC_DEFAULT then uses 244 yyrhsloc. Reported by Jim Meyering at 245 <http://lists.gnu.org/archive/html/bug-bison/2011-04/msg00002.html>. 246 * data/glr.c (yyresolveLocations): Omit definition when locations 247 are disabled. 248 (yyresolveValue): Omit yyresolveLocations invocation when 249 locations are disabled. 250 251 2011-04-16 Joel E. Denny <joeldenny (a] joeldenny.org> 252 253 gnulib, autoconf: update. 254 * README-hacking (Updating a submodule): Give advice on how to 255 determine the versions of gnulib and autoconf to which we should 256 update. 257 (Release Procedure): Note that submodules should be updated. 258 * bootstrap.conf (gnulib_modules): Rename pipe to spawn-pipe as 259 suggested in updated gnulib NEWS. 260 * gnulib: Choose a stable snapshot according to advice in Bison's 261 README-hacking. 262 * po/POTFILES.in (lib/pipe.c): Rename to... 263 (lib/spawn-pipe.c): ... this. 264 * src/output.c: Update to include spawn-pipe.h. 265 * submodules/autoconf: Update to latest for improvement in m4.m4 266 that excludes M4 with buggy strstr. The only other changes to 267 files that we use are copyright updates. 268 269 2011-04-09 Joel E. Denny <joeldenny (a] joeldenny.org> 270 271 Fix missing updates to GPLv3. 272 Reported by Tys Lefering at 273 <http://lists.gnu.org/archive/html/bison-patches/2011-04/msg00000.html>. 274 * src/print-xml.c, src/print-xml.h: In these files. 275 276 2011-03-27 Joel E. Denny <joeldenny (a] joeldenny.org> 277 278 Add -Wconflicts-sr and -Wconflicts-rr. 279 Thus, conflict reports are now affected by -Werror and -Wnone 280 (unless %expect or %expect-rr is specified). Reported by George 281 Neuner at 282 <http://lists.gnu.org/archive/html/bug-bison/2010-08/msg00002.html>. 283 * NEWS (2.5): Document. 284 * doc/bison.texinfo (Bison Options): Document. 285 * src/complain.c, src/complain.h (set_warning_issued): Export 286 function. 287 * src/conflicts.c (conflicts_print): Suppress conflict report 288 based on -Wno-conflicts-sr and -Wno-conflicts-rr, and treat 289 conflicts as errors if -Werror. 290 * src/getargs.c (warnings_flag): Initialize with 291 warnings_conflicts_sr and warnings_conflicts_rr as well. 292 (warnings_args, warnings_types): Add entries for 293 warnings_conflicts_sr and warnings_conflicts_rr. 294 (usage): Update. 295 * src/getargs.h (enum warnings): Add entries for 296 warnings_conflicts_sr and warnings_conflicts_rr. 297 * tests/conflicts.at (-W versus %expect and %expect-rr): New test 298 group. 299 * tests/local.at (AT_BISON_CHECK_NO_XML): Update now that the 300 conflict report can produce a "warnings being treated as errors" 301 message. Also, check that stderr is now fully scrubbed by -Wnone 302 when the exit status is 0. 303 304 2011-03-27 Joel E. Denny <joeldenny (a] joeldenny.org> 305 306 Pacify maintainer-check-posix. 307 Adding command-line options after the grammar file name is not 308 permitted, so disable checks that do that when 309 maintainer-check-posix is running. 310 * tests/local.at (AT_BISON_CHECK_NO_XML): Don't run the 311 problematic checks when POSIXLY_CORRECT=1. Also, for readability, 312 remove an unnecessary m4_if. 313 314 2011-03-27 Joel E. Denny <joeldenny (a] joeldenny.org> 315 316 Add -Wother so -Wnone suppresses all warnings. 317 Reported by George Neuner at 318 <http://lists.gnu.org/archive/html/bug-bison/2010-08/msg00002.html>. 319 * NEWS (2.5): Document. 320 * THANKS (George Neuner): Add. 321 * doc/bison.texinfo (Bison Options): Document. 322 * src/complain.c, src/complain.h 323 (warn_at, warn_at_indent, warn): Suppress warning if -Wno-other. 324 (midrule_value_at): New warning function, similar to yacc_at in 325 that it's controlled by its own warning category. 326 * src/getargs.c (warnings_flag): Initialize to warnings_other. 327 (warnings_args, warnings_types): Add entry for warnings_other. 328 (usage): Update. 329 * src/getargs.h (enum warnings): Add entry for warnings_other. 330 * src/gram.c (grammar_rules_useless_report): If -Wno-other, then 331 don't print useless rules. 332 * src/reader.c (symbol_should_be_used): Rather than adjusting the 333 return value based on whether midrule value warnings are enabled, 334 accept a new parameter for telling the caller whether true is 335 being returned for a potential midrule warning. 336 (grammar_rule_check): Use midrule_value_at for midrule value 337 warnings, and continue to use warn_at for all other warnings. Let 338 them check whether the warnings are enabled. 339 * tests/local.at (AT_BISON_CHECK): Update documentation. 340 (AT_BISON_CHECK_NO_XML): Check that -Wnone and --warnings=none 341 disable all warnings exercised in the test suite. 342 343 2011-03-27 Joel E. Denny <joeldenny (a] joeldenny.org> 344 345 Don't let -Wnone disable -Werror. 346 Discussed at 347 <http://lists.gnu.org/archive/html/bison-patches/2010-08/msg00009.html>. 348 * NEWS (2.5): Document. 349 * src/getargs.c (flags_argmatch): Accept a new argument that 350 specifies what flags "all" and thus "none" affect. 351 (FLAGS_ARGMATCH): Update flags_argmatch invocation. 352 * tests/input.at (-Werror is not affected by -Wnone and -Wall): 353 New test group. 354 355 2011-03-27 Joel E.

Update all cross-references 446 to this node. Also, don't imply that R/R conflicts are the only 447 kind of mysterious conflict. 448 449 2011-03-06 Joel E. Denny <joeldenny (a] joeldenny.org> 450 451 lr.default-reductions: rename "all" value to "full". 452 States that shift the error token do not have default reductions, 453 and GLR disables some default reductions, so "all" was a misnomer. 454 * doc/bison.texinfo (%define Summary): Update. 455 (Default Reductions): Update. 456 * src/print.c (print_reductions): Update. 457 * src/reader.c (prepare_percent_define_front_end_variables): 458 Update. 459 * src/tables.c (action_row): Update. 460 * tests/input.at (%define enum variables): Update. 461 * tests/reduce.at (%define lr.default-reductions): Update. 462 463 2011-03-06 Joel E. Denny <joeldenny (a] joeldenny.org> 464 465 doc: create a new Tuning LR section in the manual. 466 And clean up all other documentation of the features described 467 there. 468 * NEWS (2.5): Tweak wording of lr.type and parse.lac entries a 469 bit, update the cross-references to the manual, and point out that 470 LAC has caveats. Don't be so adamant that IELR+LAC=canonical LR. 471 That is, as the referenced section in the manual documents, LAC 472 does not fix infinite parsing loops on syntax errors. 473 * doc/bison.texinfo: Consistently drop the "(1)" suffix from LALR, 474 IELR, and LR in @cindex. 475 (%define Summary): Condense the entries for lr.default-reductions, 476 lr.keep-unreachable-states, lr.type, and parse.lac into brief 477 summaries, and cross-reference the appropriate subsections of 478 Tuning LR. For parse.lac, mention that it's only implemented for 479 deterministic parsers in C. 480 (Error Reporting): When mentioning %error-verbose, mention LAC, 481 and add cross-reference to the LAC section. 482 (Tuning LR): New section with an extended version of the 483 documentation removed from %define Summary. Change all 484 cross-references in the manual to point here instead of there. 485 (Calc++ Parser): When mentioning %error-verbose, mention LAC, and 486 add cross-reference to the LAC section. 487 (Table of Symbols): In %error-verbose and YYERROR_VERBOSE entries, 488 add cross-references to Error Reporting. 489 (Glossary): Capitalize entry titles consistently. Add definitions 490 for "defaulted state" and "unreachable state". Expand IELR 491 acronym in IELR's entry. 492 493 2011-02-20 Joel E. Denny <joeldenny (a] joeldenny.org> 494 495 doc: add bibliography to manual. 496 * doc/bison.texinfo (Mystery Conflicts): Cross-reference 497 bibliography instead of citing publications directly. 498 (Generalized LR Parsing): Likewise. 499 (Bibliography): New section. Not all entries are cross-referenced 500 yet, but that will come in future patches. 501 502 2011-02-19 Joel E. Denny <joeldenny (a] joeldenny.org> 503 504 java: test and document previous bug fix. 505 * NEWS (2.5): Document it. 506 * tests/java.at (_AT_DATA_JAVA_CALC_Y): To one of the yyerror 507 invocations, pass a location that spans multiple tokens. Change 508 yyerror to report all of a location rather than just the begin 509 position. Extend yylex and Position to count tokens on a line. 510 Remove getHashCode as it's unused. Update all expected output. 511 512 2011-02-19 Bernd Kiefer <kiefer (a] dfki.de> (tiny change) 513 514 java: fix location handling bug. 515 Reported at 516 <http://lists.gnu.org/archive/html/bison-patches/2011-02/msg00005.html>. 517 * data/lalr1.java (YYParser::yylloc): For non-empty RHS, fix 518 reversed access to location stack. 519 * THANKS (Bernd Kiefer): Add. 520 521 2010-05-11 Akim Demaille <demaille (a] gostai.com> 522 523 doc: please Emacs. 524 * doc/bison.texinfo (Local Variables): Move this after the 525 LocalWords, since the latter are looked for in the whole document, 526 while the former are looked for only at its end. 527 Require american spell checking. 528 529 2011-02-06 Joel E. Denny <joeldenny (a] joeldenny.org> 530 531 doc: clean up new subsections in manual. 532 * doc/bison.texinfo (%define Summary): Reword so it reads well as 533 a separate section. For example, add an intro, and move most of 534 the text outside of the @deffn so it is not indented so far. 535 (%code Summary): Likewise. 536 (Table of Symbols): Reword %code entry to match the %code entry in 537 Decl Summary. 538 539 2011-02-06 Joel E. Denny <joeldenny (a] joeldenny.org> 540 541 doc: finish splitting apart the manual's Decl Summary section. 542 Suggested by Akim Demaille at 543 <http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00013.html>. 544 * doc/bison.texinfo (Decl Summary): Extract most of the %define 545 entry into... 546 (%define Summary): ... this new subsection, and update all 547 cross-references. For readability of the patches, rewriting of 548 the text so it makes sense as a separate subsection will come in a 549 later patch. Moreover, the majority of the text describing the 550 various new LR features should likely move to another new section 551 somewhere. 552 553 2011-02-06 Joel E. Denny <joeldenny (a] joeldenny.org> 554 555 doc: begin to split apart the manual's Decl Summary section. 556 Discussed in thread starting at 557 <http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00013.html>. 558 * doc/bison.texinfo (Decl Summary): Extract most of the %code 559 entry into... 560 (%code Summary): ... this new subsection, and update all 561 cross-references. For readability of the patches, rewriting of 562 the text so it makes sense as a separate subsection will come in a 563 later patch. 564 565 2011-02-06 Joel E. Denny <joeldenny (a] joeldenny.org> 566 567 doc: clean up naming of various Bison files. 568 The Bison manual's names for various files associated with a Bison 569 parser has devolved into inconsistency. This patch makes the 570 naming consistent for the most important files. First, it chooses 571 "grammar file" over "input file". The former appears to be more 572 traditional in the Bison manual, and Bison has other input 573 files (skeletons). Second, it chooses "parser implementation 574 file" over names like "parser file", "parser source file", "parser 575 source code file", and "parser output file". The new name makes 576 it clearer where Bison generates the main parser implementation, 577 and it is easily distinguishable from "parser header file". 578 * doc/bison.texinfo: Implement throughout. 579 580 2011-02-06 Joel E. Denny <joeldenny (a] joeldenny.org> 581 582 doc: give credit to more of Bison's developers. 583 * doc/bison.texinfo (Introduction): Don't imply that only Robert 584 Corbett, Richard Stallman, and Wilfred Hansen have contributed to 585 Bison. However, I don't have time to write a full history, so 586 just point readers to THANKS and ChangeLog. 587 588 2011-02-06 Joel E. Denny <joeldenny (a] joeldenny.org> 589 590 doc: document experimental features better. 591 * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical 592 LR(1) are experimental. Mention Java. Normally experimental 593 features probably shouldn't be mentioned in the introduction. 594 However, if Bison's limitations to LALR(1), C, and C++ are so 595 important that they should be mentioned here, then it's important 596 to point out that Bison is beginning to escape those limitations. 597 Moreover, these particular experimental features have very little 598 chance of being removed. 599 * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are 600 experimental. 601 602 2011-01-29 Joel E. Denny <joeldenny (a] joeldenny.org> 603 604 Do not allow identifiers that start with a dash. 605 This cleans up our previous fixes for a bug whereby Bison 606 discarded `.field' in `$-1.field'. The previous fixes were less 607 restrictive about where a dash could appear in an identifier, but 608 the restrictions were hard to explain. That bug was reported and 609 this final fix was originally suggested by Paul Hilfinger. This 610 also fixes a remaining bug reported by Paul Eggert whereby Bison 611 parses `%token ID -123' as `%token ID - 123' and handles `-' as an 612 identifier. Now, `-' cannot be an identifier. Discussed in 613 threads beginning at 614 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>, 615 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>. 616 * NEWS (2.5): Update entry describing the dash extension to 617 grammar symbol names. Also, move that entry before the named 618 references entry because the latter mentions the former. 619 * doc/bison.texinfo (Symbol): Update documentation for symbol 620 names. As suggested by Paul Eggert, mention the effect of periods 621 and dashes on named references. 622 (Decl Summary): Update documentation for unquoted %define values, 623 which, as a side effect, can no longer start with dashes either. 624 * src/scan-code.l (id): Implement. 625 * src/scan-gram.l (id): Implement. 626 * tests/actions.at (Exotic Dollars): Extend test group to exercise 627 bug reported by Paul Hilfinger. 628 * tests/input.at (Symbols): Update test group, and extend to 629 exercise bug reported by Paul Eggert. 630 * tests/named-refs.at (Stray symbols in brackets): Update test 631 group. 632 ($ or @ followed by . or -): Likewise. 633 * tests/regression.at (Invalid inputs): Likewise. 634 635 2011-01-24 Joel E. Denny <joeldenny (a] joeldenny.org> 636 637 * data/yacc.c: Fix last apostrophe warning from xgettext. 638 639 2011-01-09 Paul Eggert <eggert (a] cs.ucla.edu> 640 641 Fix minor problems encountered by a fresh bootstrap. 642 * data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments, 643 as they confuse xgettext, which tries to parse them as C character 644 constants in a preprocessor directive. 645 * data/yacc.c (yy_lac): Don't use printf %d format on *yyesp, as 646 that expression might not promote to int on some platforms. 647 * src/parse-gram.c, src/parse-gram.h: Regenerate. 648 649 2011-01-09 Joel E. Denny <joeldenny (a] joeldenny.org> 650 651 Improve error messages for `$' or `@' followed by `.' or `-'. 652 Previously, for this special case of an invalid reference, the 653 usual "symbol not found in production:" was printed. However, 654 because the symbol name was parsed as the empty string, that 655 message was followed immediately by a newline instead of a symbol 656 name. In reality, this is a syntax error, so the reference is 657 invalid regardless of the symbols actually appearing in the 658 production. Discussed at 659 <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>. 660 * src/scan-code.l (parse_ref): Report the above case as a syntax 661 error. Other than that, continue to handle this case like any 662 other invalid reference that Bison manages to parse because 663 "possibly meant" messages can still be helpful to the user. 664 * tests/named-refs.at ($ or @ followed by . or -): New test group. 665 666 2011-01-08 Joel E. Denny <joeldenny (a] joeldenny.org> 667 668 doc: don't use @acronym. 669 Lately, many GNU packages are dropping it. See 670 <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00003.html>. 671 * doc/bison.texinfo: Remove all uses. 672 673 2011-01-05 Alex Rozenman <rozenman (a] gmail.com> 674 675 Do not allow identifiers that start with a negative number. 676 Reported by Paul Hilfinger as a side effect of named references 677 support at 678 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>. 679 Suggested by Paul Eggert. 680 * src/scan-code.l ({letter}, {id}): Adjust lexical definitions. 681 * src/scan-gram.l ({letter}, {id}): Likewise. 682 683 2011-01-03 Joel E. Denny <joeldenny (a] joeldenny.org> 684 685 * ChangeLog (2011-01-02): improve description. 686 687 2011-01-03 Joel E. Denny <joeldenny (a] joeldenny.org> 688 689 maint: don't update copyright years in bootstrap. 690 * .x-update-copyright: Add entry for bootstrap. 691 * bootstrap: Remove 2011 from copyright years. The bootstrap 692 version we're currently using comes from an older version of 693 gnulib. 694 * bootstrap.conf (bootstrap_sync): Add comments explaining this 695 issue. 696 697 2011-01-02 Joel E. Denny <joeldenny (a] joeldenny.org> 698 699 maint: run "make update-copyright". 700 701 2011-01-02 Joel E. Denny <joeldenny (a] joeldenny.org> 702 703 maint: prepare to use year ranges in copyright notices. 704 * README (Copyright statements): New section explaining the range 705 notation. The GNU maintainers document requires this explanation: 706 <http://www.gnu.org/prep/maintain/maintain.html#Copyright-Notices>. 707 I copied our explanation from coreutils. 708 * build-aux/update-b4-copyright: Revert 2010-06-17 changes that 709 disabled Bison's automated use of ranges. 710 * cfg.mk (update-copyright-env): Likewise. 711 712 2011-01-02 Joel E. Denny <joeldenny (a] joeldenny.org> 713 714 Correct my email address. 715 * ChangeLog: In all recent entries. 716 * THANKS (Joel E. Denny): Here. 717 718 2010-12-19 Joel E. Denny <joeldenny (a] joeldenny.org> 719 720 doc: cleanup. 721 * NEWS (2.5): Try to sort entries according to how interesting 722 users might find them. 723 724 2010-12-19 Joel E. Denny <joeldenny (a] joeldenny.org> 725 726 doc: cleanup. 727 * NEWS (2.5): Make some minor improvements to wording, and format 728 entries more consistently. 729 * doc/bison.texinfo (Language and Grammar): Point out that IELR 730 and canonical LR are experimental features. 731 (Decl Summary): In list of %define variables, make wording more 732 consistent. Improve discussion of using LALR for GLR. 733 734 2010-12-19 Joel E. Denny <joeldenny (a] joeldenny.org> 735 736 parse.lac: document. 737 * NEWS (2.5): Add entry for LAC, and mention LAC in entry for 738 other corrections to verbose syntax error messages. 739 * doc/bison.texinfo (Decl Summary): Rewrite entries for 740 lr.default-reductions and lr.type to be clearer, to mention 741 %nonassoc's effect on canonical LR, and to mention LAC. Add entry 742 for parse.lac. 743 (Glossary): Add entry for LAC. 744 745 2010-12-11 Joel E. Denny <joeldenny (a] joeldenny.org> 746 747 parse.lac: implement exploratory stack reallocations. 748 * data/yacc.c: Rename %define variable parse.lac.es-capacity to 749 parse.lac.es-capacity-initial. Accept parse.lac.memory-trace 750 with values of "failures" (default) or "full". 751 (b4_declare_parser_state_variables): Add yyesa, yyes, and 752 yyes_capacity variables. 753 (YYSTACK_USE_ALLOCA): Ignore it if LAC requested. 754 (YYSTACK_ALLOC, YYSTACK_FREE, YYSTACK_ALLOC_MAXIMUM): Define if 755 LAC requested. 756 (YYCOPY_NEEDED): New cpp macro. 757 (YYCOPY): Define if LAC requested. 758 (yy_lac_stack_realloc): New function implementing stack 759 reallocations. Use YYMAXDEPTH for maximum stack size given that 760 the stack should never need to grow larger than the main state 761 stack needs to grow without LAC. 762 (YY_LAC_ESTABLISH): Update yy_lac invocation. 763 (yy_lac): Add arguments for exploratory stack memory data 764 recorded in the main parser. Invoke yy_lac_stack_realloc when 765 reallocation is necessary. 766 (yysyntax_error): Add the same new arguments and pass them to 767 yy_lac. 768 (yypstate_delete): Free yyes if necessary. 769 (yyesa, yyes, yyes_capacity): #define these to yypstate members 770 in the case of push parsing. 771 (yyparse, yypush_parse): Initialize yyes and yyes_capacity. 772 Update yysyntax_error invocations. At yyreturn, free yyes if 773 necessary. 774 * src/parse-gram.y: %define parse.lac full. 775 * tests/input.at (LAC: errors for %define): Extend for 776 parse.lac-memory-trace. 777 * tests/regression.at (LAC: Exploratory stack): Extend to check 778 that stack reallocs happen when expected. 779 (LAC: Memory exhaustion): Update to use YYMAXDEPTH and 780 parse.lac.es-capacity-initial. 781 782 2010-12-11 Joel E. Denny <joeldenny (a] joeldenny.org> 783 784 parse.lac: implement as %define variable. 785 LAC = lookahead correction. See discussion at 786 <http://lists.gnu.org/archive/html/bison-patches/2009-09/msg00034.html>. 787 However, one point there must be corrected: because of %nonassoc, 788 LAC is *not* always redundant for lr.type=canonical-lr. 789 * data/yacc.c: Accept values of "none" (default) or "full" for 790 parse.lac. Accept %define parse.lac.es-capacity to specify 791 capacity of LAC's temporary exploratory stack. It defaults to 20 792 and, for now, will not grow dynamically. 793 (b4_lac_flag, b4_lac_if): New m4 macros. Evaluate as true for 794 parse.lac!=none. 795 (YYBACKUP): Invoke YY_LAC_DISCARD. 796 (YY_LAC_ESTABLISH, YY_LAC_DISCARD): New cpp macros that invoke 797 yy_lac and track when it needs to be invoked 798 (yy_lac): New function that, given the current stack, determines 799 whether a token can eventually be shifted. Return status mimics 800 yyparse return status. 801 (yysyntax_error): Change yystate argument to yyssp so stack top 802 can be passed to yy_lac. If LAC is requested, build expected 803 token list by invoking yy_lac for every token instead of just 804 checking the current state for lookaheads. Return 2 if yy_lac 805 exhausts memory. 806 (yyparse, yypush_parse): Use local variable yy_lac_established and 807 cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC. 808 Update yysyntax_error invocation. Add yyexhaustedlab code if LAC 809 is requested. 810 * tests/conflicts.at (%nonassoc and eof): Extend to check the 811 effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full. 812 (%error-verbose and consistent errors): Likewise. 813 (LAC: %nonassoc requires splitting canonical LR states): New test 814 group demonstrating how LAC can fix canonical LR. 815 * tests/input.at (LAC: Errors for %define): New test group. 816 * tests/regression.at (LAC: Exploratory stack): New test group. 817 (LAC: Memory exhaustion): New test group. 818 819 2010-11-21 Joel E. Denny <joeldenny (a] joeldenny.org> 820 821 build: use gnulib's new bootstrap_sync option. 822 Now, whenever we update bison's copy of gnulib, bootstrap will 823 update itself the next time it's run. 824 * bootstrap: Copy from latest gnulib for bootstrap_sync support. 825 * bootstrap.conf (bootstrap_sync): Set to true. 826 * gnulib: Update to latest so bootstrap is in sync now. 827 828 2010-11-07 Joel E. Denny <joeldenny (a] joeldenny.org> 829 830 yysyntax_error: adjust prior fixes for branch-2.5's lalr1.cc. 831 On master, there is no yychar in lalr1.cc, but there is on 832 branch-2.5, and the prior cherry-pick of "Fix handling of yychar 833 manipulation in user semantic actions" wasn't adjusted for that 834 difference. 835 * data/lalr1.cc (yy::parser::parse): Translate yychar before 836 every use of yytoken, and add comments explaining this approach. 837 * tests/conflicts.at (%error-verbose and consistent errors): 838 Extend to test yychar manipulation with lalr1.cc. 839 840 2010-11-07 Joel E. Denny <joeldenny (a] joeldenny.org> 841 842 yysyntax_error: fix for consistent error with lookahead. 843 * NEWS (2.5): Document. 844 * data/yacc.c (yysyntax_error): In a verbose syntax error 845 message while in a consistent state with a default action (which 846 must be an error action given that yysyntax_error is being 847 invoked), continue to drop the expected token list, but don't 848 drop the unexpected token unless there actually is no lookahead. 849 Moreover, handle that internally instead of returning 1 to tell 850 the caller to do it. With that meaning of 1 gone, renumber 851 return codes more usefully. 852 (yyparse, yypush_parse): Update yysyntax_error usage. Most 853 importantly, set yytoken to YYEMPTY when there's no lookahead. 854 * data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the 855 unexpected token unless there actually is no lookahead. 856 * data/lalr1.cc (yy::parser::parse): If there's no lookahead, 857 set yytoken to yyempty_ before invoking yysyntax_error_. 858 (yy::parser::yysyntax_error_): Again, don't drop the unexpected 859 token unless there actually is no lookahead. 860 * data/lalr1.java (YYParser::parse): If there's no lookahead, 861 set yytoken to yyempty_ before invoking yysyntax_error. 862 (YYParser::yysyntax_error): Again, don't drop the unexpected 863 token unless there actually is no lookahead. 864 * tests/conflicts.at (%error-verbose and consistent 865 errors): Extend test group to further reveal how the previous 866 use of the simple "syntax error" message was too general. Test 867 yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected 868 failure. 869 * tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move 870 to... 871 * tests/local.at: ... here. 872 (_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition. 873 (AT_BISON_OPTION_POPDEFS): Pop it. 874 (AT_FULL_COMPILE): Extend to handle Java. 875 876 2010-11-07 Joel E. Denny <joeldenny (a] joeldenny.org> 877 878 yysyntax_error: more preparation for readability of next patch. 879 There are no behavioral changes here. 880 * data/glr.c (yyreportSyntaxError): Reorganize. 881 * data/lalr1.cc (yy::parser::yysyntax_error_): Reorganize. 882 * tests/conflicts.at (%error-verbose and consistent errors): 883 Reorganize. 884 885 2010-11-07 Joel E. Denny <joeldenny (a] joeldenny.org> 886 887 yysyntax_error: prepare for readability of next patches. 888 These are purely whitespace changes that result in ugly code 889 but that make the next couple of patches much easier to read. 890 * data/glr.c (yyreportSyntaxError): Reindent. 891 * data/lalr1.cc (yy::parser::yysyntax_error_): Reindent. 892 * data/lalr1.java (YYParser::yysyntax_error): Reindent. 893 * data/yacc.c (yysyntax_error): Reindent. 894 895 2010-10-31 Joel E. Denny <joeldenny (a] joeldenny.org> 896 897 yysyntax_error: improve invocation readability. 898 * data/yacc.c (yyparse, yypush_parse): For yysyntax_error 899 invocation, get rid of the while loop, which is misleading 900 because there are really at most two iterations. 901 902 2010-10-31 Joel E. Denny <joeldenny (a] joeldenny.org> 903 904 * ChangeLog: Correct some errors in previous entries. 905 906 2010-10-17 Joel E. Denny <joeldenny (a] joeldenny.org> 907 908 maint: re-anchor all .gitignore entries. 909 * bootstrap: Copy from gnulib's latest for the fix to 910 automatically anchor entries it constructs. 911 * gnulib: Update to latest just so it has the same bootstrap. 912 * .gitignore, build-aux/.gitignore, doc/.gitignore: 913 * lib/.gitignore, m4/.gitignore, po/.gitignore: 914 * runtime-po/.gitignore: Re-anchor all entries. 915 916 2010-10-08 Paul Eggert <eggert (a] cs.ucla.edu> 917 918 Fix portability problem on OpenBSD 4.7. 919 920 Jim Meyering reported this in 921 <http://lists.gnu.org/archive/html/bug-bison/2010-10/msg00007.html>. 922 * data/yacc.c: Use EXIT_SUCCESS as a witness for stdlib.h, 923 not _STDLIB_H. EXIT_SUCCESS has been defined by the standard 924 for quite some time. 925 * src/parse-gram.c, src/parse-gram.h: Regenerate. 926 * tests/regression.at: Tamper with the renamed witness. 927 928 Adjust to recent changes to gnulib bootstrap. 929 930 * .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore: 931 * examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore: 932 * po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore: 933 * tests/.cvsignore: Remove; I don't use CVS to maintain Bison 934 anymore and don't know of anybody else who does. If someone needs 935 these files, they can resurrect them. 936 * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore: 937 * m4/.gitignore, po/.gitignore, runtime-po/.gitignore: 938 Omit leading '/', since bootstrap omits it. 939 Adjust file names to match current contents better. 940 * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook 941 installed just for us. 942 * bootstrap.conf (excluded_files): Don't exclude codeset.m4, 943 glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now 944 needed somehow. Don't have time to look into why. 945 (gnulib_modules): Change malloc to malloc-gnu. Do we really assume 946 the GNU malloc behavior, where malloc (0) != NULL unless we're 947 out of storage? If not, we can omit malloc-gnu; but for now I left 948 it in to be safe. 949 (vc_ignore): Remove. 950 * README-hacking: Renamed from HACKING, since gnulib bootstrap now 951 uses that convention. 952 953 2010-08-05 Joel E. Denny <joeldenny (a] joeldenny.org> 954 955 Version 2.4.3. 956 * NEWS (2.4.3): Set date. 957 958 2010-08-04 Joel E. Denny <joeldenny (a] joeldenny.org> 959 960 maint: add gettext version to release announcements. 961 Suggested by Paul Hilfinger at 962 <http://lists.gnu.org/archive/html/bison-patches/2010-07/msg00019.html> 963 <http://lists.gnu.org/archive/html/bison-patches/2010-08/msg00002.html>. 964 * cfg.mk (bootstrap-tools): Add gettext. 965 966 2010-08-04 Joel E. Denny <joeldenny (a] joeldenny.org> 967 968 doc: fix -W and %expect documentation some. 969 * NEWS (2.4.3): Mention that there are documentation fixes. 970 * doc/bison.texinfo (Expect Decl): Make it clear that %expect 971 turns conflicts into errors not warnings. 972 (Shift/Reduce): Likewise. 973 (Bison Options): Don't mention -Wsyntax.

Denny <jdenny (a] ces.clemson.edu> 1351 1352 portability: fix several issues with M4 subprocess. 1353 1354 M4's output pipe was not being drained upon fatal errors during 1355 scan_skel. As a result, broken-pipe messages from M4 were seen 1356 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a 1357 failure in the test suite. The problem was that, on platforms 1358 where the default disposition for SIGPIPE is ignore instead of 1359 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and 1360 then reported it. However, there's some sort of race condition, 1361 because the new test group occasionally succeeded. 1362 Reported by Albert Chin at 1363 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>. 1364 1365 There were also problems with the test suite livelocking on 1366 Tru64 5.1b.

Along the 1372 way, clean up file name conflict handling, which was affected by 1373 the broken-pipe problem before the switch. 1374 * NEWS (2.4.2): Document. 1375 * THANKS (Didier Godefroy): Add. 1376 * bootstrap.conf (gnulib_modules): Add pipe. 1377 * gnulib: Update to latest to make sure we have all the latest 1378 fixes. 1379 * lib/Makefile.am (libbison_a_SOURCES): Remove subpipe.h and 1380 subpipe.c. 1381 * po/POTFILES.in (lib/subpipe.c): Remove. 1382 * src/files.c (compute_output_file_names): Update invocations 1383 of output_file_name_check. 1384 (output_file_name_check): In the case that the grammar file 1385 would be overwritten, use complain instead of fatal, but replace 1386 the output file name with /dev/null. Use the /dev/null solution 1387 for the case of two conflicting output files as well because it 1388 seems safer in case Bison one day tries to open both files at 1389 the same time. 1390 * src/files.h (output_file_name_check): Update prototype. 1391 * src/output.c (output_skeleton): Use create_pipe_bidi and 1392 wait_subprocess.

Denny <jdenny (a] clemson.edu> 1455 1456 Fix some comments concerning LR(0) versus LALR(1). 1457 1458 Stop equating LR(0) with nondeterminism and LALR(1) with 1459 determinism. That is, if all states are consistent, then LR(0) 1460 tables are deterministic. On the other hand, LALR(1) tables 1461 might be nondeterministic before conflict resolution, and GLR 1462 permits LALR(1) tables to remain nondeterministic. 1463 * src/LR0.c, src/LR0.h: Here. 1464 * src/lalr.c, src/lalr.h: Here. 1465 * src/main.c (main): Here. 1466 * src/state.c, src/state.h: Here. 1467 1468 * src/ielr.h (ielr): In preconditions, expect LR(0) not LALR(1) 1469 parser tables. 1470 1471 2010-01-04 Joel E.

Denny <jdenny (a] clemson.edu> 1565 1566 Fix handling of yychar manipulation in user semantic actions. 1567 The problem was that yacc.c didn't always update the yychar 1568 translation afterwards. However, other skeletons appear to be 1569 fine. glr.c appears to already translate yychar before every 1570 use. lalr1.cc does not define yychar and does not document its 1571 replacement, yyla, for users. It does provide yyclearin, but 1572 that does not manipulate yyla and thus requires no translation 1573 update. In lalr1.java, yychar is out of scope during semantic 1574 actions. 1575 * NEWS (2.5): Document. 1576 * data/yacc.c (YYBACKUP): Don't bother translating yychar into 1577 yytoken here. 1578 (yyparse, yypush_parse): Instead, translate before every use of 1579 yytoken, and add comments explaining this approach. 1580 * tests/actions.at (Destroying lookahead assigned by semantic 1581 action): New test group checking that translation happens before 1582 lookahead destructor calls at parser return. Previously, 1583 incorrect destructors were called. 1584 * tests/conflicts.at (%error-verbose and consistent 1585 errors): New test group checking that translation happens at 1586 syntax error detection before the associated verbose error 1587 message and the associated lookahead destructor calls. While 1588 the destructor call is fixed by this patch, the verbose error 1589 message is currently incorrect due to another bug (see 1590 comments in test group), so this is an expected failure for now. 1591 1592 2009-12-21 Joel E.

Denny <jdenny (a] clemson.edu> 1768 1769 yysyntax_error: avoid duplicate lookahead collection. 1770 Except when memory reallocation is required, this change 1771 eliminates the need to invoke yysyntax_error twice and thus to 1772 repeat the collection of lookaheads. It also prepares for 1773 future extensions that will make those repetitions more 1774 expensive and that will require additional memory management in 1775 yysyntax_error. Finally, it fixes an obscure bug already 1776 exercised in the test suite. 1777 * data/yacc.c (yysyntax_error): Add arguments for message 1778 buffer variables stored in the parser. Instead of size, return 1779 status similar to yyparse status but indicating success of 1780 message creation. Other than the actual reallocation of the 1781 message buffer, import and clean up memory management code 1782 from... 1783 (yyparse, yypush_parse): ... here. 1784 * tests/regression.at (%error-verbose overflow): No longer an 1785 expected failure. 1786 1787 2009-09-23 Joel E.

Denny <jdenny (a] clemson.edu> 1883 1884 Clean up yacc.c a little. 1885 * data/yacc.c: Clean up M4 for readability, and make output 1886 whitespace more consistent. For the main parse function 1887 comment, instead of saying "yyparse or yypush_parse", say either 1888 "yyparse" or "yypush_parse" depending on which it actually is. 1889 1890 2009-09-03 Joel E.

This 1938 makes it consistent with the function definition in scan-code.l 1939 anyway. 1940 1941 2009-08-28 Joel E. Denny <jdenny (a] clemson.edu> 1942 1943 %define: accept unquoted values. 1944 * NEWS (2.5): Group all %define changes together, and document 1945 this one. Remove quotes in IELR and canonical LR entry. 1946 * doc/bison.texinfo: Remove quotes in most examples throughout. 1947 (Decl Summary): Update %define documentation. 1948 (Table of Symbols): Likewise. 1949 * src/ielr.c (LrType): Update documentation. 1950 * src/parse-gram.y (content.opt): Add production for ID. 1951 * tests/calc.at: Remove quotes in most tests. 1952 * tests/existing.at: Likewise. 1953 * tests/input.at: Likewise. 1954 * tests/local.at: Likewise. 1955 * tests/push.at: Likewise. 1956 * tests/reduce.at: Likewise. 1957 * tests/torture.at: Likewise. 1958 1959 2009-08-28 Joel E.

Denny <jdenny (a] clemson.edu> 1981 1982 tests: use perl for printing special sequences to files. 1983 And skip tests if perl is not available. This is better than 1984 playing tricks with shell portability. Suggested by Akim 1985 Demaille. 1986 * tests/input.at (Bad character literals): Use it here for 1987 omitting final newlines. 1988 (Bad escapes in literals): Use it here for special characters. 1989 1990 2009-08-26 Joel E. Denny <jdenny (a] clemson.edu> 1991 1992 tests: show a use of %define lr.default-reductions "consistent" 1993 * tests/conflicts.at (%nonassoc and eof): Extend to test that it 1994 prevents the omission of expected tokens for %error-verbose. 1995 1996 2009-08-26 Akim Demaille <demaille (a] gostai.com> 1997 1998 tests: portability fix. 1999 * tests/input.at (Bad escapes in literals): Don't expect "echo 2000 '\0'" to output \ then 0. 2001 2002 2009-08-26 Joel E. Denny <jdenny (a] clemson.edu> 2003 2004 Actually handle the yytable zero value correctly this time. 2005 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Don't 2006 mention zero values in the YYTABLE comments. 2007 * data/glr.c (yytable_value_is_error): Don't check for zero 2008 value. 2009 * data/lalr1.cc (yy_table_value_is_error_): Likewise. 2010 * data/yacc.c (yytable_value_is_error): Likewise. 2011 * data/lalr1.java (yy_table_value_is_error_): Likewise. 2012 (yysyntax_error): Fix typo in code: use yytable_ not yycheck_. 2013 * src/tables.h: In header comments, explain why it's useless to 2014 check for a zero value in yytable. 2015 2016 2009-08-25 Joel E. Denny <jdenny (a] clemson.edu> 2017 2018 More fixes related to last two patches. 2019 * data/c.m4 (b4_table_value_equals): Comment that YYID must be 2020 defined. 2021 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix 2022 yytable comments: zero indicates syntax error not default 2023 action. 2024 * data/glr.c (yyis_pact_ninf): Rename to... 2025 (yypact_value_is_default): ... this. 2026 (yyisDefaultedState): Update for rename. 2027 (yyis_table_ninf): Rename to... 2028 (yytable_value_is_error): ... this, and check for value zero 2029 besides just YYTABLE_NINF. 2030 (yygetLRActions): Check for default value from yypact. It 2031 appears that this check is always performed before this function 2032 is invoked, and so adding the check here is probably redundant. 2033 However, the code may evolve after this subtlety is forgotten. 2034 Also, update for rename to yytable_value_is_error. Because that 2035 macro now checks for zero, a different but equivalent branch of 2036 the if-then-else here is evaluated. 2037 (yyreportSyntaxError): Update for rename to 2038 yytable_value_is_error. The zero condition was mishandled 2039 before. 2040 (yyrecoverSyntaxError): Update for renames. No behavioral 2041 changes. 2042 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_): 2043 New function. 2044 (yy_table_value_is_error_): New function. 2045 (parse): Use new functions where possible. No behavioral 2046 changes. 2047 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_. 2048 The zero condition was mishandled before. 2049 * data/yacc.c (yyis_pact_ninf): Rename to... 2050 (yypact_value_is_default): ... this. 2051 (yyis_table_ninf): Rename to... 2052 (yytable_value_is_error): ... this, and check for value zero 2053 besides just YYTABLE_NINF. 2054 (yysyntax_error): Update for rename to yytable_value_is_error. 2055 The zero condition was mishandled before. 2056 (yyparse): Update for renames. No behavioral changes. 2057 * src/tables.h: Improve comments about yypact, yytable, etc. 2058 more. Most importantly, say yytable value of zero means syntax 2059 error not default action. 2060 2061 2009-08-25 Joel E. Denny <jdenny (a] clemson.edu> 2062 2063 Fix %error-verbose for conflicts resolved by %nonassoc. 2064 * NEWS (2.5): Document. 2065 * data/glr.c (yyreportSyntaxError): Fix this by checking 2066 yyis_table_ninf. 2067 * data/yacc.c (yysyntax_error): Likewise. 2068 * data/lalr1.cc (yysyntax_error_): Fix this by checking 2069 yytable_ninf_. 2070 * data/lalr1.java (yysyntax_error): Likewise. 2071 * tests/conflicts.at (%nonassoc and eof): Update expected output 2072 and remove FIXME. 2073 2074 2009-08-25 Joel E.

Denny <jdenny (a] clemson.edu> 2091 2092 Use locale when quoting. 2093 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use 2094 quote rather than implementing quoting here. 2095 2096 2009-08-20 Eric Blake <ebb9 (a] byu.net> 2097 2098 Make previous patch more robust. 2099 * src/output.c (ARRAY_CARDINALITY): New macro, copied from 2100 argmatch.h. 2101 (output_skeleton): Use it. 2102 Suggested by Akim Demaille. 2103 2104 Import latest m4/m4.m4. 2105 * submodules/autoconf: Update to autoconf 2.64. 2106 * configure.ac (M4_GNU_OPTION): New define. 2107 * src/output.c (output_skeleton): Use it to resolve FIXME. 2108 * NEWS: Mention this. 2109 2110 2009-08-19 Joel E. Denny <jdenny (a] clemson.edu> 2111 2112 Fix complaints about escape sequences. 2113 Discussed starting at 2114 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>. 2115 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): 2116 For a \0 and similar escape sequences meaning the null 2117 character, report an invalid escape sequence instead of an 2118 invalid null character because the latter does not actually 2119 appear in the user's input. 2120 In all escape sequence complaints, don't escape the initial 2121 backslash, and don't quote when the sequence appears at the end 2122 of the complaint line unless there's whitespace that quotearg 2123 won't escape. 2124 Consistently say "invalid" not "unrecognized". 2125 Consistently prefer "empty character literal" over "extra 2126 characters in character literal" warning for invalid escape 2127 sequences; that is, consistently discard those sequences. 2128 * tests/input.at (Bad escapes in literals): New. 2129 2130 2009-08-19 Akim Demaille <demaille (a] gostai.com> 2131 2132 doc: fixes. 2133 * doc/bison.texinfo: Fix minor Texinfo errors. 2134 2135 2009-08-19 Akim Demaille <demaille (a] gostai.com> 2136 2137 doc: %initial-action to initialize yylloc. 2138 Reported by Bill Allombert. 2139 * doc/bison.texinfo: Set fill-column to 76. 2140 (Location Type): Document the use of %initial-action to initialize 2141 yylloc. 2142 2143 2009-08-18 Joel E.

Denny <jdenny (a] clemson.edu> 2214 2215 Miscellaneous code readability improvements. 2216 2217 * src/reader.c (reader): Move %define front-end variable 2218 defaults and checking into... 2219 (prepare_percent_define_front_end_variables): ... this new 2220 function. 2221 2222 * src/scan-gram.l (INITIAL): For consistency with string 2223 literals, don't store open quote on character literal. It's 2224 discarded before returning anyway. 2225 (SC_ESCAPED_CHARACTER): Similarly, don't store close quote. 2226 Make length test more readable, and make the character stored 2227 for an empty literal more obvious while consistent with the 2228 previous behavior. 2229 2230 * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to 2231 USER_NUMBER_HAS_STRING_ALIAS throughout. 2232 * src/symtab.c (symbol_make_alias): Remove comment from symtab.c 2233 that is repeated in symtab.h. Improve argument names to make it 2234 clear which side of the symbol-string alias pair is which. 2235 (symbol_check_alias_consistency): Improve local variable names 2236 for the same purpose. 2237 * src/symtab.h (struct symbol): Make comments about aliases 2238 clearer. 2239 (symbol_make_alias): Improve comments and argument name. 2240 * src/output.c (token_definitions_output): Update for rename to 2241 USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases. 2242 2243 2009-08-08 Alex Rozenman <rozenman (a] gmail.com> 2244 2245 Convert "misleading reference" messages to warnings. 2246 * src/scan-code.l: New function 'show_sub_messages', more 2247 factoring. 2248 * tests/named-ref.at: Adjust tests. 2249 2250 2009-08-06 Joel E.

However, if any of our developers still use 2314 Flex 2.5.4, they'll need to stop configuring with 2315 --enable-gcc-warnings because "%option noinput" didn't work 2316 correctly until Flex 2.5.6. 2317 * src/scan-gram.l: Likewise. 2318 * src/scan-skel.l: Likewise. 2319 2320 2009-07-31 Alex Rozenman <rozenman (a] gmail.com> 2321 2322 Fix --enable-gcc-warnings problems. 2323 * src/reader.c: Adjust variable names. 2324 * src/scan-code.l: Fix prototypes and adjust names. 2325 * src/named-ref.c: Remove redundant "if". 2326 2327 2009-07-29 Joel E.

Discussed starting at 4932 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>. 4933 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's 4934 definition in order to avoid Gnulib headers since we don't use config.h 4935 here. 4936 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR 4937 rather than AT_DATA so that config.h is included. 4938 4939 2007-07-01 Joel E. Denny <jdenny (a] ces.clemson.edu> 4940 4941 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF 4942 instead of fprintf. Guard these functions with #if YYDEBUG instead of 4943 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison 4944 and so that YYFPRINTF is guaranteed to be defined here. 4945 4946 2007-05-29 Joel E. Denny <jdenny (a] ces.clemson.edu> 4947 4948 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace 4949 with... 4950 (muscle_percent_define_check_values): ... this more helpful function. 4951 Again, it's not used yet, but it will be. 4952 * src/muscle_tab.h: Likewise. 4953 4954 Improve some comments in parser table construction. 4955 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base. 4956 (generate_states): Don't mention ruleset, which is internal to closure. 4957 * src/closure.c (closure): Explain sorting of core and itemset, which 4958 is required for this function to behave correctly. 4959 * src/closure.h (closure): Mention sorting. 4960 4961 2007-05-28 Joel E. Denny <jdenny (a] ces.clemson.edu> 4962 4963 * src/lalr.c (state_lookahead_tokens_count): For code readability, 4964 move the check for disabled transitions to an aver since conflict 4965 resolution hasn't happened yet. 4966 4967 * src/lalr.c (state_lookahead_tokens_count): Remove the check that 4968 labels a state as inconsistent just because it has error transitions. 4969 The original form of this check appeared in revision 1.1 of lalr.c, 4970 which was committed on 1991-12-21. Now (at least), changing the 4971 consistency label on such a state appears to have no useful effect in 4972 any of the places it is examined, which I enumerate below. The key 4973 point to understanding each item in this enumeration is that a state 4974 with an error transition is labelled consistent in the first place only 4975 if it has no rules, so the check cannot matter for states that have 4976 rules. (1) Labelling a state as inconsistent will cause set_conflicts 4977 to try to identify its conflicts, and a state must have *rules* to have 4978 conflicts. (2) Labelling a state as inconsistent will affect how 4979 action_row sets the default *rule* for the state. (3) Labelling a 4980 state as inconsistent will cause build_relations to add lookback edges 4981 to *rules* in that state. 4982 * src/state.h (struct state): Word the comment for member consistent 4983 more carefully. 4984 4985 2007-05-27 Joel E.

Denny <jdenny (a] ces.clemson.edu> 5425 5426 Implement support for relative and absolute skeleton file names. 5427 Discussed starting at 5428 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>. 5429 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry. 5430 (Bison Options): Document in --skeleton entry. 5431 * src/output.c (output_skeleton): Use strncpy rather than strcpy since 5432 full_skeleton can't necessarily hold all of pkgdatadir. 5433 If the specified skeleton file name contains a `/', don't prepend 5434 pkgdatadir. 5435 * src/parse-gram.y (prologue_declaration): If the specified skeleton 5436 file name contains a `/', prepend the grammar file directory. 5437 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at. 5438 * skeletons.at: New file. 5439 (relative skeleton file names): New test case. 5440 (installed skeleton file names): New test case. 5441 * tests/testsuite.at: Include skeletons.at. 5442 5443 * bootstrap: Update copyright to 2007. 5444 5445 2007-01-17 Paolo Bonzini <bonzini (a] gnu.org> 5446 5447 * bootstrap: Remove occurrences of .#bootmp from the files. 5448 5449 2007-01-17 Akim Demaille <akim (a] epita.fr> 5450 5451 * doc/bison.texinfo (Calc++ Parser): Don't try to alias 5452 nonterminals. 5453 Use per-type %printer. 5454 5455 2007-01-17 Joel E. Denny <jdenny (a] ces.clemson.edu> 5456 5457 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4, 5458 data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc, 5459 djgpp/config.site, src/files.c, src/files.h, src/main.c, 5460 src/muscle_tab.c, src/muscle_tab.h, src/parse-gram.y, src/reader.h, 5461 src/scan-skel.h, src/scan-skel.l, tests/actions.at, tests/calc.at, 5462 tests/glr-regression.at, tests/input.at, tests/local.at, 5463 tests/output.at, tests/torture.at: Update copyright to 2007. 5464 5465 2007-01-16 Akim Demaille <akim (a] epita.fr> 5466 5467 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an 5468 error code. 5469 (Calc++ Scanner): Exit with failure if we can't open the input 5470 file. 5471 Accept "-" standing for stdin. 5472 (Calc++ Top Level): Print the result only if the parsing was 5473 successful. 5474 5475 2007-01-16 Akim Demaille <akim (a] epita.fr> 5476 5477 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line. 5478 5479 2007-01-15 Paolo Bonzini <bonzini (a] gnu.org> 5480 and Joel E. Denny <jdenny (a] ces.clemson.edu> 5481 5482 Clean up %define and %code implementation in M4 some. Most 5483 importantly, rename all related macros to be in the b4_percent_define 5484 and b4_percent_code namespaces. Also, complete support for `.' in 5485 %define variable names and %code qualifiers. 5486 * data/bison.m4 (b4_check_user_names): Check for special 5487 "SKELETON-NAMESPACE(name)" macros instead of using two nested 5488 m4_foreach loops. 5489 (b4_get_percent_define, b4_get_percent_code): Rename to... 5490 (b4_percent_define_get, b4_percent_code_get): ... these. 5491 Extend documentation with examples. 5492 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use 5493 b4_percent_define_skeleton_variables and 5494 b4_percent_code_skeleton_qualifiers. 5495 Expect any value for the %define variable `foo' to be stored in the 5496 macro named `b4_percent_define(foo)'; expect any %code blocks for the 5497 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)'; 5498 expect any unqualified %code blocks to be stored in a macro named 5499 `b4_percent_code_unqualified'. 5500 Use m4_indir so that %define variable names and %code qualifiers can 5501 contain `.', which is allowed by the grammar parser. 5502 (b4_percent_define_default): New macro to set a default value for a 5503 %define variable. 5504 (m4_wrap): Update wrapped code, and fix some underquoting. 5505 (b4_check_user_names_wrap): Update and define outside the m4_wrap. 5506 Expect grammar uses of %define variables and %code qualifiers to be 5507 defined in b4_percent_define_user_variables and 5508 b4_percent_code_user_qualifiers. 5509 * data/c++.m4: Use b4_percent_define_default rather than 5510 m4_define_default. Fix some underquoting. Skeleton usage of %define 5511 variable define_location_comparison now implies skeleton usage of 5512 %define variable filename_type. 5513 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc, 5514 data/push.c, data/yacc.c: Update macro names. 5515 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update 5516 muscle names. 5517 5518 2007-01-14 Juan Manuel Guerrero <juan.guerrero (a] gmx.de> 5519 5520 DJGPP specific issues. 5521 5522 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific 5523 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default. 5524 5525 2007-01-09 Joel E. Denny <jdenny (a] ces.clemson.edu> 5526 5527 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to 5528 run parsers in all tests so that Valgrind is invoked during 5529 maintainer-check-valgrind. 5530 (Duplicate representation of merged trees): Free all semantic values. 5531 (Duplicated user destructor for lookahead): Likewise. 5532 5533 2007-01-09 Joel E. Denny <jdenny (a] ces.clemson.edu> 5534 5535 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a 5536 command-line prefix. 5537 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is 5538 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't 5539 miss Valgrind messages. 5540 (Exploding the Stack Size with Malloc): Likewise. 5541 5542 2007-01-09 Joel E. Denny <jdenny (a] ces.clemson.edu> 5543 5544 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be 5545 locals. Reported by Juan Manuel Guerrero at 5546 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>. 5547 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if. 5548 Fix some indentation also. 5549 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment 5550 explaining this issue. 5551 5552 2007-01-09 Paolo Bonzini <bonzini (a] gnu.org> 5553 and Joel E. Denny <jdenny (a] ces.clemson.edu> 5554 5555 Simplify union and prologue handling, and escape union and lex/parse 5556 params with digraphs. 5557 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default 5558 values to the empty string since these are no longer guaranteed 5559 initialized by the front-end. 5560 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add 5561 braces around b4_user_stype since this is no longer done by the 5562 front-end. 5563 * src/files.c, src/files.h (pre_prologue_obstack, 5564 post_prologue_obstack): Remove. 5565 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header 5566 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped 5567 with digraphs. This fixes lex params and parse params. 5568 * src/muscle_tab.h (muscle_pair_list_grow): Update comments. 5569 * src/output.c (prepare): Remove muscle insertion of the prologues. 5570 (output): Remove freeing of pre_prologue_obstack and 5571 post_prologue_obstack. 5572 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather 5573 than prologue_augment for prologue parsing so you don't need prologue 5574 obstacks. 5575 (grammar_declaration): For %union RHS, use `braceless' instead of 5576 "{...}" so that braces are already stripped and code is escaped with 5577 digraphs. 5578 * src/reader.c (prologue_augment): Remove. 5579 (reader): Remove initialization of pre_prologue_obstack and 5580 post_prologue_obstack. 5581 * src/reader.h (prologue_augment): Remove. 5582 5583 * data/c.m4: Remove stray parenthesis. 5584 5585 2007-01-08 Joel E. Denny <jdenny (a] ces.clemson.edu> 5586 5587 Remove quotes from variables names in %define directives and from 5588 qualifiers in %code directives, and restrict the characters that are 5589 allowed in them to M4-friendly ones. For %define, continue to support 5590 the quoted form as a deprecated feature. Discussed starting at 5591 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>. 5592 * NEWS (2.3a+): Add entry for the change to %define. Update entry for 5593 %code. 5594 * doc/bison.texinfo (Prologue Alternatives): Update. 5595 (Decl Summary): In %defines entry, update mention of `%code requires' 5596 and `%code provides'. 5597 (C++ Location Values): Update %define uses. 5598 (Calc++ Parser Interface): Likewise. 5599 (Calc++ Parser): Likewise, and update `%code requires' uses. 5600 (Table of Symbols): Update %code documentation. 5601 * src/parse-gram.y (prologue_declaration): For %define variables, use 5602 `variable' instead of `STRING'. 5603 (grammar_declaration): For %code qualifiers, use `ID' instead of 5604 `STRING'. 5605 (variable): New nonterminal that takes an `ID' or a `STRING'. 5606 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code 5607 and %define uses. 5608 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use. 5609 * tests/input.at (Reject unused %code qualifiers): Update %code uses. 5610 (%define errors): Update %define uses. 5611 5612 2007-01-08 Joel E. Denny <jdenny (a] ces.clemson.edu> 5613 5614 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING 5615 instead of muscle_insert for %define values so that M4-special 5616 characters are replaced with digraphs. 5617 * tests/input.at (%define errors): Extend to check weird values. 5618 5619 2007-01-08 Joel E. Denny <jdenny (a] ces.clemson.edu> 5620 5621 Instead of having skeletons declare all valid %define variables and 5622 %code qualifiers, provide macros that retrieve the associated values 5623 and build these lists automatically. Thus Bison will now warn when a 5624 variable or qualifier is not used by the skeleton in the current 5625 invocation regardless of whether it might sometimes be used by that 5626 skeleton in other invocations. Also, move all %define value macros to 5627 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE} 5628 form, which is replaced by %code. 5629 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to... 5630 (b4_check_user_names): ... this, and change the series of valid name 5631 arguments to a single list argument for names used in the skeleton 5632 similar to the existing list argument for names used in the grammar. 5633 Warn instead of complaining. 5634 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define 5635 values and %code code, to format %code code properly, and to build 5636 lists of all %define variables and %code qualifiers used in the 5637 skeleton: b4_skeleton_percent_define_variables and 5638 b4_skeleton_percent_code_qualifiers. 5639 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers): 5640 Remove, and... 5641 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that 5642 the skeleton names lists can finish building first. In place of 5643 b4_used_percent_define_variables and b4_used_percent_code_qualifiers, 5644 expect the lists b4_user_percent_define_variables and 5645 b4_user_percent_code_qualifiers. 5646 * data/c++.m4: Where setting default values for b4_parser_class_name, 5647 b4_location_type, b4_filename_type, b4_namespace, and 5648 b4_define_location_comparison, update their names to the 5649 b4_percent_define_ namespace. 5650 * data/glr.c: Don't use b4_check_percent_define_variables and 5651 b4_check_percent_code_qualifiers. Use b4_get_percent_code. 5652 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define. 5653 (b4_parser_class_name, b4_namespace): Define these using 5654 b4_get_percent_define for parser_class_name and namespace. 5655 * data/location.cc: Use b4_get_percent_define. 5656 * data/push.c: Don't use b4_check_percent_define_variables and 5657 b4_check_percent_code_qualifiers. Use b4_get_percent_code. 5658 * data/yacc.c: Likewise, and don't call m4_exit in 5659 b4_use_push_for_pull_if or m4_wrap code will never execute. 5660 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list): 5661 Rename to... 5662 (muscle_grow_user_name_list): ... this for consistency with the 5663 terminology used in bison.m4. 5664 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to 5665 %define variable names, and rename muscle used_percent_define_variables 5666 to user_percent_define_variables. 5667 (grammar_declaration): Rename muscle used_percent_code_qualifiers to 5668 user_percent_code_qualifiers. 5669 (content): Remove. 5670 (content.opt): Replace content RHS with STRING RHS so %define "NAME" 5671 {CODE} form is no longer accepted. 5672 * tests/input.at (Reject bad %code qualifiers): Rename to... 5673 (Reject unused %code qualifiers): ... this, and update test output. 5674 (%define error): Update test output. 5675 5676 2007-01-07 Joel E. Denny <jdenny (a] ces.clemson.edu> 5677 5678 Check for unrecognized %define variables similar to checking for 5679 unrecognized %code qualifiers. Check for redefined %define variables. 5680 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that 5681 generalizes... 5682 (b4_check_percent_code_qualifiers): ... this, which now wraps it. 5683 (b4_check_percent_define_variables): New, also wraps it. 5684 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define 5685 variables using b4_check_percent_define_variables. 5686 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as 5687 all those exercised in the test suite and all those listed in the 5688 `Default values' section of c++.m4. Are there others? 5689 * data/push.c, data/yacc.c: Declare no valid %define variables. 5690 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function, 5691 similar to muscle_find, but it works even when the muscle stores a 5692 const value. 5693 (muscle_grow_used_name_list): New function for constructing the used 5694 name list muscles that b4_check_for_unrecognized_names requires. 5695 * src/parse-gram.y (prologue_declaration): Warn if a variable is 5696 %define'd more than once. Define the b4_used_percent_define_variables 5697 muscle with muscle_grow_used_name_list. 5698 (grammar_declaration): Abbreviate %code code with 5699 muscle_grow_used_name_list. 5700 * tests/input.at (%define errors): New. 5701 5702 2007-01-06 Joel E. Denny <jdenny (a] ces.clemson.edu> 5703 5704 Provide warn_at, complain_at, and fatal_at function callbacks to the 5705 skeletons, and use this for %code qualifier complaints. 5706 * data/bison.m4 (b4_error_at): New, invoked by... 5707 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap 5708 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and 5709 @fatal_at(...@) directives. 5710 (b4_check_percent_code_qualifiers): Rewrite to expect locations for 5711 qualifiers in b4_used_percent_code_qualifiers and to use 5712 b4_complain_at. 5713 * src/location.c, src/location.h (boundary_set_from_string): New global 5714 function. 5715 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global 5716 function. 5717 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers 5718 to b4_used_percent_code_qualifiers. 5719 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static 5720 function. 5721 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments. 5722 (lineno): Rename to... 5723 (out_lineno): ... this so I don't misunderstand it again. 5724 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines 5725 here; these newlines are in the input but not the output file. 5726 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to... 5727 (at_directive_perform): ... this new static function, and add handling 5728 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@) 5729 directives. 5730 * tests/input.at (Reject bad %code qualifiers): Update test output with 5731 locations and extend. 5732 5733 * tests/output.at (Output file name: [, Output file name: ]): Remove 5734 bogus comment about these tests failing. 5735 5736 2007-01-06 Joel E. Denny <jdenny (a] ces.clemson.edu> 5737 5738 Clean up b4_check_percent_code_qualifiers a little. 5739 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers 5740 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite 5741 documentation and add examples. 5742 * src/parse-gram.y (grammar_declaration): Double-M4-quote those 5743 qualifiers here. 5744 5745 2007-01-05 Joel E. Denny <jdenny (a] ces.clemson.edu> 5746 5747 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop 5748 unreliable -- especially when they're hidden inside another macro. 5749 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, 5750 data/c.m4: Remove m4_divert(-1). 5751 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc, 5752 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with 5753 m4_divert_push(0) and m4_divert_pop(0). 5754 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and 5755 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is 5756 pushed and popped by m4sugar, should be first on the stack. 5757 5758 Provide warn, complain, and fatal function callbacks to the skeletons. 5759 This provides more flexibility than m4_fatal, improves the error 5760 message format, and captures messages for translation. Discussed 5761 starting at 5762 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>. 5763 * data/bison.m4 (b4_error): New, invoked by... 5764 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the 5765 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@) 5766 directives. Because these M4 macros might be called when the current 5767 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus 5768 the previous removal of uses of m4_divert, which caused trouble. 5769 (b4_check_percent_code_qualifiers): Use b4_complain instead of 5770 m4_fatal to report unrecognized %code qualifiers. 5771 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++ 5772 push parser requests. 5773 * data/glr.c: Use b4_complain instead of m4_fatal to report 5774 non-deterministic push parser requests. 5775 Update @output usage to @output(...@) form. 5776 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to 5777 report missing %defines. Update @output usage to @output(...@) form. 5778 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to 5779 @output(...@) form. 5780 * src/main.c (main): Invoke skel_scanner_free. 5781 * src/scan-skel.h (skel_scanner_free): Prototype new function. 5782 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the 5783 obstack_for_string from flex-scanner.h. 5784 (YY_DECL): Use to declare skel_lex static. 5785 (decode_at_digraphs): Remove; now handled in the new 5786 SC_AT_DIRECTIVE_ARG start condition. 5787 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static 5788 functions. 5789 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc, 5790 at_directive_argv): New static globals. 5791 (INITIAL): Use fail_for_invalid_at. 5792 Don't parse `@output file_name\n' or `@basename(...@)'. Instead, 5793 recognize the start of a generalized `@directive(...@)' form and 5794 start... 5795 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the 5796 directive args (using the new obstack_for_string), to decode the 5797 contained @ diagraphs, and to perform the directive. It recognizes 5798 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and 5799 @output(...@). 5800 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by 5801 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter, 5802 `@,'. 5803 (scan_skel): Initialize obstack_for_string on the first call. 5804 (skel_scanner_free): New function to free obstack_for_string. 5805 * tests/input.at (Reject bad %code qualifiers): Update test output. 5806 5807 2007-01-04 Joel E. Denny <jdenny (a] ces.clemson.edu> 5808 5809 Consolidate the 4 prologue alternative directives (%code, %requires, 5810 %provides, and %code-top) into a single %code directive with an 5811 optional qualifier field. Discussed at 5812 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>. 5813 * NEWS (2.3a+): Rewrite the existing entry for the prologue 5814 alternatives. 5815 * doc/bison.texinfo (Prologue Alternatives): Update. 5816 (Decl Summary): Update to %code "requires" and %code "provides". 5817 (Calc++ Parser): Update to %code "requires". 5818 (Table of Symbols): Remove entries for %requires, %provides, and 5819 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry. 5820 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these 5821 are replaced by b4_percent_code_provides and b4_percent_code_requires, 5822 which are skeleton-specific. 5823 (b4_check_percent_code_qualifiers): New. A skeleton can use this to 5824 declare what %code qualifiers it supports and to complain if any other 5825 qualifiers were used in the grammar. 5826 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires]) 5827 and b4_user_code([b4_percent_code_provides]) in place of 5828 b4_user_requires and b4_user_provides. 5829 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise. 5830 Add b4_user_code([b4_percent_code_top]) and 5831 b4_user_code([b4_percent_code]). 5832 Invoke b4_check_percent_code_qualifiers. 5833 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES, 5834 PERCENT_REQUIRES): Remove. 5835 (grammar_declaration): Remove RHS's for %code-top, %provides, and 5836 %requires. Rewrite the %code RHS as the unqualified form defining the 5837 muscle b4_percent_code. Add another RHS for the qualified %code form, 5838 which defines muscles of the form b4_percent_code_QUALIFIER and the 5839 b4_used_percent_code_qualifiers muscle. 5840 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES, 5841 PERCENT_REQUIRES): Remove. 5842 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use 5843 %code "requires" and %code "provides". 5844 * tests/input.at (Reject bad %code qualifiers): New. 5845 5846 2007-01-03 Joel E. Denny <jdenny (a] ces.clemson.edu> 5847 5848 Use the new code_props interface for destructors and printers. 5849 * src/symtab.h (symbol, semantic_type): Remove destructor_location and 5850 printer_location members, and change the type of the destructor and 5851 printer members to code_props. 5852 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set, 5853 symbol_printer_get, semantic_type_destructor_set, 5854 semantic_type_printer_set, default_tagged_destructor_set, 5855 default_tagless_destructor_set, default_tagged_printer_set, 5856 default_tagless_printer_set): Use code_props in arguments and return 5857 types in place of char const * and location. 5858 (symbol_destructor_location_get, symbol_printer_location_get): Remove 5859 since the locations are now contained in the return of 5860 symbol_destructor_get and symbol_printer_get. 5861 * src/output.c (symbol_destructors_output, symbol_printers_output): 5862 Replace with... 5863 (symbol_code_props_output): ... this to eliminate duplicate code. 5864 (output_skeleton): Update to use symbol_code_props_output. 5865 * src/reader.c (symbol_should_be_used): Update use of 5866 symbol_destructor_get. 5867 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set): 5868 Update uses of the various _destructor_set and _printer_set functions. 5869 * src/symtab.c: (default_tagged_destructor_location, 5870 default_tagless_destructor_location, default_tagged_printer_location, 5871 default_tagless_printer_location): Remove since we... 5872 (default_tagged_destructor, default_tagless_destructor, 5873 default_tagged_printer, default_tagless_printer): ... change the type 5874 of these to code_props. 5875 (symbol_new, semantic_type_new, symbol_destructor_set, 5876 semantic_type_destructor_set, symbol_destructor_get, 5877 symbol_printer_set, semantic_type_printer_set, symbol_printer_get, 5878 symbol_check_alias_consistency, default_tagged_destructor_set, 5879 default_tagless_destructor_set, default_tagged_printer_set, 5880 default_tagless_printer_set): Update. 5881 (symbol_destructor_location_get, symbol_printer_location_get): Remove. 5882 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for 5883 code_props members. 5884 (symbol_print): Use SYMBOL_CODE_PRINT. 5885 5886 2007-01-03 Joel E. Denny <jdenny (a] ces.clemson.edu> 5887 5888 Use the new code_props interface for rule actions. 5889 * src/symlist.h (symbol_list): Replace action, action_location, and 5890 used members with a code_props action_props member. 5891 * src/reader.c (symbol_should_be_used, grammar_rule_check, 5892 grammar_midrule_action, grammar_current_rule_merge_set, 5893 grammar_current_rule_symbol_append, packgram): Update. 5894 * src/scan-code.h (translate_rule_action): Remove, no longer used. 5895 * src/scan-code.l (handle_action_dollar): Update. 5896 (translate_rule_action): Remove, no longer used. 5897 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update. 5898 5899 2007-01-02 Joel E. Denny <jdenny (a] ces.clemson.edu> 5900 5901 Use the new code_props interface in parse-gram.y. 5902 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt): 5903 Update all uses of translate_* functions to use the new code_props 5904 interface and to use gram_scanner_last_string_free and 5905 code_scanner_last_string_free where possible. 5906 (grammar_declaration): symbol_list_destructor_set and 5907 symbol_list_printer_set now perform the translation, so don't do it 5908 here. Use gram_scanner_last_string_free where possible. 5909 * src/scan-code.h, src/scan-code.l (translate_symbol_action, 5910 translate_code): Remove, no longer used. 5911 * src/symlist.h, src/symlist.c (symbol_list_destructor_set, 5912 symbol_list_printer_set): Perform code translation here rather than 5913 depending on the caller to do so. 5914 5915 * src/symlist.h (struct symbol_list): Correct some documentation typos. 5916 * src/scan-gram.h (gram_last_string): Remove declaration. 5917 * src/scan-gram.l (last_string): Declare it static. 5918 5919 2007-01-02 Joel E. Denny <jdenny (a] ces.clemson.edu> 5920 5921 Encapsulate code properties and related functionality for the various 5922 destructors, printers, and actions into a code_props structure and 5923 interface. This patch merely implements code_props in scan-code.h and 5924 scan-code.l. Future patches will rewrite other modules to use it. 5925 Discussed starting at 5926 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>. 5927 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to 5928 consistently initialize const structs that have an empty location 5929 field. 5930 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT 5931 to ensure consistency. 5932 * src/scan-code.h (code_props): New structure. 5933 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New 5934 function, macro, and const global variable for initializing a 5935 code_props with no code. 5936 (code_props_plain_init, code_props_symbol_action_init, 5937 code_props_rule_action_init, code_props_translate_code): The rest of 5938 the new code_props functional interface. Among other things, the init 5939 functions set the code_props kind field so that 5940 code_props_translate_code will know whether to behave like 5941 translate_symbol_action, translate_rule_action, or translate_code. 5942 These old translate functions must remain until all other modules are 5943 updated to use the new code_props interface. 5944 (code_scanner_last_string_free): New function similar to 5945 gram_scanner_last_string_free. 5946 (code_scanner_free): Add documentation. 5947 * src/scan-code.l: Implement the new interface. 5948 (code_lex): Make it static, add a code_props* argument, and remove the 5949 rule argument. 5950 (last_string): New static global similar to the one in scan-gram.l. 5951 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex 5952 instead of rule. 5953 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the 5954 code_props since Bison may one day use this information for destructors 5955 and printers. 5956 (<*><<EOF>>): Use STRING_FINISH so that last_string is set. 5957 (handle_action_dollar): Use symbol_list_n_get and set used flag 5958 directly since symbol_list_n_used_set is removed. 5959 (translate_action): Add a code_props* argument and remove the rule, 5960 action, and location arguments. Pass the code_props* on to code_lex. 5961 (translate_rule_action, translate_symbol_action, translate_code): 5962 Rewrite as wrappers around the new code_props interface. 5963 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since 5964 it would eventually need to break the encapsulation of code_props. 5965 5966 2007-01-01 Joel E. Denny <jdenny (a] ces.clemson.edu> 5967 5968 * etc/.cvsignore: New. 5969 5970 2007-01-01 Joel E. Denny <jdenny (a] ces.clemson.edu> 5971 5972 Add maintainer-push-check to run maintainer-check using push parsing in 5973 place of pull parsing where available. 5974 * Makefile.am (maintainer-push-check): New. 5975 * data/bison.m4 (b4_use_push_for_pull_if): New. 5976 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if 5977 appropriately based on their existing values. 5978 (yypush_parse): Don't print push-parser-specific diagnostics if push 5979 parsing is being used in place of pull parsing. 5980 * data/yacc.c: If push parsing should replace pull parsing, redirect to 5981 push.c. 5982 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment 5983 variable, and insert b4_use_push_for_pull_flag into muscles. 5984 * tests/Makefile.am (maintainer-push-check): New. 5985 5986 2006-12-31 Joel E. Denny <jdenny (a] ces.clemson.edu> 5987 5988 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse 5989 (whether successful or failed) so that yypush_parse can be invoked 5990 again to start a new parse using the same yypstate. 5991 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to 5992 check multiple yypull_parse invocations on the same yypstate. For pull 5993 mode, extend to check multiple yyparse invocations. 5994 (Exploding the Stack Size with Alloca): Extend to try with 5995 %push-pull-parser. 5996 (Exploding the Stack Size with Malloc): Likewise. 5997 5998 * tests/calc.at (Simple LALR Calculator): Don't specify 5999 %skeleton "push.c" since %push-pull-parser implies that now. 6000 * tests/headers.at (export YYLTYPE): Don't check for the push 6001 declarations. Otherwise, this test case can't be used to see if push 6002 mode can truly emulate pull mode. 6003 * tests/input.at (Torturing the Scanner): Likewise. 6004 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove. 6005 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use 6006 AT_YACC_IF, which now includes the case of push mode since %skeleton 6007 need not be used for push mode. This will be more intuitive once 6008 push.c is renamed to yacc.c. 6009 6010 2006-12-31 Joel E. Denny <jdenny (a] ces.clemson.edu> 6011 6012 For push mode, convert yyparse from a macro to a function, invoke yylex 6013 instead of passing a yylexp argument to yypull_parse, and don't 6014 generate yypull_parse or yyparse unless %push-pull-parser is declared. 6015 Discussed starting at 6016 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>. 6017 * data/bison.m4 (b4_pull_if): New. 6018 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH. 6019 * data/push.c: Improve M4 quoting a little. 6020 (b4_generate_macro_args, b4_parenthesize): Remove. 6021 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse] 6022 any time a pull parser is requested. 6023 Don't #define this as a wrapper around yypull_parse. Instead, when 6024 both push and pull are requested, make it a function that does that 6025 same thing. 6026 (yypull_parse): If there's a b4_prefix, #define this to 6027 b4_prefix[pull_parse] when both push and pull are requested. 6028 Don't define this as a function unless both push and pull are 6029 requested. 6030 Remove the yylexp argument and hard-code yylex invocation instead. 6031 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of 6032 %push-parser. 6033 * src/getargs.c (pull_parser): New global initialized to true. 6034 * getargs.h (pull_parser): extern it. 6035 * src/output.c (prepare): Insert pull_flag muscle. 6036 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token. 6037 (prologue_declaration): Set both push_parser and pull_parser = true for 6038 %push-pull-parser. Set push_parser = true and pull_parser = false for 6039 %push-parser. 6040 * src/scan-gram.l: Don't accept %push_parser as an alternative to 6041 %push-parser since there's no backward-compatibility concern here. 6042 Scan %push-pull-parser. 6043 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser 6044 instead of %push-parser. 6045 * tests/headers.at (export YYLTYPE): Make yylex static, and don't 6046 prototype it in the module that calls yyparse. 6047 * tests/input.at (Torturing the Scanner): Likewise. 6048 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well. 6049 6050 2006-12-26 Joel E. Denny <jdenny (a] ces.clemson.edu> 6051 6052 Update etc/bench.pl. Optimize push mode a little (the yyn change 6053 deserves most of the credit). 6054 * Makefile.am (SUBDIRS): Add etc subdirectory. 6055 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile. 6056 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult, 6057 yytoken, yyval, and yyloc declarations to... 6058 (yyparse or yypush_parse): ... here to improve performance. For 6059 yypush_parse invocations after the first, be sure to assign yyn its old 6060 value again. 6061 (yypstate_new): Don't bother initializing the yyresult field since the 6062 initial value isn't used. 6063 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list, 6064 remove the #define that, in push mode, set it to yyps->NAME. 6065 * etc/Makefile.am: New. 6066 * etc/bench.pl: Remove and build it instead from... 6067 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke 6068 "tests/bison" from the build directory by default rather than just 6069 invoking "bison" from $PATH. 6070 (calc_grammar): Update push parser code: don't declare yylval globally, 6071 don't define yyparse_wrapper, and don't #define yyparse. 6072 (bench_grammar): Update to check all working combinations of yacc.c, 6073 push.c, impure, pure, pull, and push. 6074 6075 2006-12-25 Joel E. Denny <jdenny (a] ces.clemson.edu> 6076 6077 For push mode, add pull wrappers around yypush_parse. 6078 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros. 6079 (yypull_parse): New function wrapping yypush_parse. 6080 (yyparse): New #define wrapping yypull_parse. 6081 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser 6082 is declared. 6083 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode, 6084 prototype yylex in the module that calls yyparse, and don't prototype 6085 yyparse there. Otherwise, the yyparse expansion won't compile. 6086 * tests/input.at (Torturing the Scanner): Likewise. 6087 6088 2006-12-25 Joel E. Denny <jdenny (a] ces.clemson.edu> 6089 6090 Enable push parsers to operate in impure mode. Thus, %push-parser no 6091 longer implies %pure-parser. The point of this change is to move 6092 towards being able to test the push parser code by running the entire 6093 test suite as if %push-parser had been declared. 6094 * data/push.c (yypush_parse): For impure mode, remove the 6095 yypushed_char, yypushed_val, and yypushed_loc arguments. 6096 Instead, declare these as local variables initialized to the global 6097 yychar, yylval, and yylloc. 6098 For the first yypush_parse invocation only, restore the initial values 6099 of these global variables when it's time to read a token since they 6100 have been overwritten. 6101 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for 6102 %push-parser. 6103 * tests/calc.at (Simple LALR(1) Calculator): Always declare 6104 %pure-parser along with %push-parser since this test case was designed 6105 for pure push parsers. 6106 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused. 6107 (AT_YACC_OR_PUSH_IF): New. 6108 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but 6109 add a note that it's still wrong for some cases (as it has been for a 6110 while). 6111 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since 6112 %push-parser no longer implies %pure-parser. 6113 6114 2006-12-20 Joel E. Denny <jdenny (a] ces.clemson.edu> 6115 6116 Remove some unnecessary differences between the pull parser code and 6117 the push parser code. This patch enables yynerrs in push mode. 6118 * data/push.c: Reformat M4 a little. 6119 (b4_yyerror_range): Remove and convert all uses to just yyerror_range. 6120 (b4_declare_scanner_communication_variables): Don't omit yynerrs just 6121 because push mode is on. Instead, if pure mode is on, move yynerrs 6122 to... 6123 (b4_declare_parser_state_variables): ... here. 6124 (yynerrs, yyerror_range): For push mode, #define each NAME in this list 6125 to yyps->NAME so it can be used in yypush_parse. 6126 (yypush_parse): Don't omit uses of yynerrs in push mode. 6127 6128 2006-12-20 Joel E. Denny <jdenny (a] ces.clemson.edu> 6129 6130 Fix bug such that the first pushed token's value and location are 6131 sometimes overwritten (sometimes by %initial-action) before being used. 6132 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and 6133 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity. 6134 For the first yypush_parse invocation, initialize yychar to YYEMPTY to 6135 more closely mimic the pull parser logic. 6136 Don't copy the pushed token to yychar, yylval, and yylloc until it's 6137 time to read a token, which is after any initialization of yylval and 6138 yylloc. 6139 (gottoken): Rename label to... 6140 (yyread_pushed_token): ... for clarity and to avoid infringing on the 6141 user namespace. 6142 6143 2006-12-20 Joel E. Denny <jdenny (a] ces.clemson.edu> 6144 6145 Rearrange initialization of the parser state variables so that the 6146 skeleton doesn't have to have a copy for pull mode and another for push 6147 mode. This patch also fixes at least a bug such that yylloc was not 6148 initialized (with b4_location_initial_line and 6149 b4_location_initial_column) upon calling yypush_parse. However, that 6150 initialization now overwrites the first token's location; 6151 %initial-action assigning @$ already did the same thing, and both bugs 6152 will be fixed in a later patch. 6153 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa. 6154 (b4_declare_parser_state_variables): Remove initialization of yytoken, 6155 yyss, yyvs, yyls, and yystacksize. 6156 (yypstate_new): Remove initialization of some yypstate fields: yystate, 6157 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and 6158 yylsp. 6159 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to 6160 yyps->NAME so it can be used in yypush_parse. 6161 (yyparse or yypush_parse): For yypush_parse, don't print the 6162 "Starting parse" diagnostic for invocations after the first. 6163 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for 6164 yypush_parse, only do it for the first invocation. 6165 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc 6166 initialization to occur in yypush_parse but only on the first 6167 invocation. 6168 6169 2006-12-19 Joel E. Denny <jdenny (a] ces.clemson.edu> 6170 6171 * data/push.c: Add CPP guards around push parser declarations in both 6172 the header and the code file. 6173 In the code file, move the push parser declarations to the same place 6174 they appear in the header file. 6175 Clean up the M4 some, especially the inconsistent underquoting in 6176 some b4_c_function_def and b4_c_function_decl uses. 6177 6178 2006-12-19 Joel E. Denny <jdenny (a] ces.clemson.edu> 6179 6180 Encapsulate the push parser state variables into an M4 macro so the 6181 push skeleton doesn't have to list them again for pull mode's yyparse. 6182 For push mode, remove yypush_parse's local equivalents of these 6183 variables to eliminate unnecessary copying between the two sets at 6184 run-time. This patch also fixes at least a bug related to multiple 6185 %initial-action invocations in push mode. 6186 * data/push.c (b4_declare_parser_variables): Rename to... 6187 (b4_declare_scanner_communication_variables): ... this for clarity and 6188 update both uses. 6189 (b4_declare_yyparse_variables): Remove and move its contents to the one 6190 spot where it was invoked. 6191 (b4_declare_parser_state_variables): New macro containing the parser 6192 state variables required by push mode. 6193 (struct yypstate): Replace all fields but yynew with 6194 b4_declare_parser_state_variables. 6195 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs, 6196 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define 6197 each NAME in this list to yyps->NAME so it can be used in yypush_parse. 6198 (yyparse or yypush_parse): For yyparse in pull mode, replace local 6199 parser state variable declarations with 6200 b4_declare_parser_state_variables. 6201 Don't initialize parser state variables when calling yypush_parse since 6202 yypstate_new already does that. 6203 Invoke the user's initial action only upon the first yypush_parse 6204 invocation. 6205 Remove all code that copies between the local parser state variables 6206 and the yypstate. 6207 6208 2006-12-19 Joel E. Denny <jdenny (a] ces.clemson.edu> 6209 6210 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to 6211 prevent a name collision in a future patch where these names will 6212 sometimes be #define'd. 6213 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field 6214 since it no longer has the same name as the existing argument. 6215 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE. 6216 6217 2006-12-19 Paolo Bonzini <bonzini (a] gnu.org> 6218 and Joel E. Denny <jdenny (a] ces.clemson.edu> 6219 6220 * doc/bison.texinfo (Decl Summary): In the %language entry, mention 6221 that the argument is case-insensitive, and there's no `=' here. 6222 For the %skeleton entry, mention that %language is better. 6223 (Bison Options): Likewise for --language and --skeleton. Move the 6224 --skeleton entry so that the `Tuning the parser' section is sorted 6225 alphabetically on long options. 6226 (C++ Bison Interface): Don't use the word skeleton. Don't explain the 6227 %language directive in detail here; cross-reference the %language 6228 documentation instead. 6229 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than 6230 `%require "2.3b"' so that the example is always up-to-date. 6231 (Table of Symbols): Add entries for %language and %skeleton. 6232 * examples/extexi (normalize): Instead of replacing every %require 6233 argument with the current Bison version, just substitute for 6234 `@value{VERSION}'. This guarantees that we're testing what actually 6235 appears in the documentation. 6236 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)' 6237 rather than `@VERSION@'. 6238 6239 2006-12-18 Paul Eggert <eggert (a] cs.ucla.edu> 6240 6241 * NEWS: Reword the %language news a bit, and put it earlier. 6242 6243 * src/getargs.c (skeleton_arg): Last arg is now location const *. 6244 Rewrite to simplify the logic. 6245 (language_argmatch): Likewise. 6246 (program_name): We now own this var. 6247 * src/getargs.h (struct bison_language): Use char[] rather than 6248 const char *. 6249 6250 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim 6251 Java is supported. 6252 * src/complain.c (program_name): Remove decl; no longer needed. 6253 * src/main.c (program_name): Remove; now belongs to getargs. 6254 6255 2006-12-18 Paolo Bonzini <bonzini (a] gnu.org> 6256 6257 * NEWS: Document %language. 6258 6259 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4. 6260 6261 * data/c-skel.m4, data/c++-skel.m4: New files. 6262 * data/glr.c: Complain on push parsers. 6263 6264 * doc/bison.texinfo (C++ Parser Interface): Prefer %language 6265 over %skeleton. 6266 (Decl Summary): Document %language and %skeleton. 6267 (Command line): Document -L. 6268 6269 * examples/extexi: Rewrite %require directive. 6270 * examples/calc++/Makefile.am: Pass VERSION to extexi. 6271 6272 * src/files.c (compute_exts_from_gc): Look in language structure 6273 for .y extension. 6274 (compute_file_name_parts): Check whether .tab should be added. 6275 * src/getargs.c (valid_languages, skeleton_prio, language_prio): 6276 (language, skeleton_arg, language_argmatch): New. 6277 (long_options): Add --language. 6278 (getargs): Use skeleton_arg, add -L/--language. 6279 * src/getargs.h: Include location.h. 6280 (struct bison_language, language, skeleton_arg, language_argmatch): New. 6281 * src/output.c (prepare): Pick default skeleton from struct language. 6282 Don't dispatch C skeletons here. 6283 * src/parse-gram.y (PERCENT_LANGUAGE): New. 6284 (prologue_declaration): Add "%language" rule, use skeleton_arg. 6285 * src/scan-gram.l ("%language"): New rule. 6286 6287 * tests/calc.at: Test %skeleton and %language. 6288 * tests/local.at (AT_SKEL_CC_IF): Look for %language. 6289 (AT_GLR_IF): Look for %skeleton "glr.cc". 6290 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite. 6291 (AT_YACC_IF): Reject %language. 6292 6293 2006-12-18 Paul Eggert <eggert (a] cs.ucla.edu> 6294 6295 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type', 6296 since it wasn't used; only the typedef name 'semantic_type' is needed. 6297 Also, omit trailing white space. 6298 6299 * bootstrap: Sync from coreutils. 6300 (gnulib_extra_files): Add build-aux/announce.gen. 6301 (slurp): Adjust .gitignore files like .cvsignore files. 6302 * build-aux/announce-gen: Remove from CVS, since bootstrap 6303 now creates this. 6304 6305 2006-12-16 Joel E. Denny <jdenny (a] ces.clemson.edu> 6306 6307 Make %push-parser imply %pure-parser. This fixes several bugs; see 6308 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>. 6309 * src/parse-gram.y (prologue_declaration): For %push-parser, also set 6310 pure_parser = true. 6311 * data/push.c: Don't bother testing b4_push_if when deciding whether 6312 to expand b4_declare_parser_variables globally. 6313 (yypush_parse): Likewise in here. 6314 6315 * data/push.c (yypush_parse): Add b4_parse_param to arguments. 6316 (yy_reduce_print): Reformat M4 for readability. 6317 6318 2006-12-15 Bob Rossi <bob (a] brasko.net> 6319 and Joel Denny <jdenny (a] ces.clemson.edu> 6320 6321 * data/push.c (yypstate): Add typedef, and update all uses of 6322 struct yypstate to just yypstate. 6323 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well. 6324 6325 2006-12-14 Bob Rossi <bob (a] brasko.net> 6326 6327 * data/push.c (yypush_parse): Declare prototype regardless of 6328 %locations option. 6329 6330 2006-12-14 Bob Rossi <bob (a] brasko.net> 6331 6332 * data/push.c (yyparse): Remove the prototype and the #define when in 6333 push-parser mode. 6334 6335 2006-12-13 Bob Rossi <bob (a] brasko.net> 6336 6337 * data/push.c (yypstate_init): Rename to... 6338 (yypstate_new): ... this and use b4_c_function_def. 6339 (yypstate_delete): New. 6340 (yypush_parse): Change parameters yynval and yynlloc to be const. 6341 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and 6342 yypstate_delete functions. 6343 6344 2006-12-13 Joel E. Denny <jdenny (a] ces.clemson.edu> 6345 6346 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our 6347 strange test case titles. Reported by Bob Rossi. 6348 6349 2006-12-13 Paul Eggert <eggert (a] cs.ucla.edu> 6350 6351 * TODO: Add pointer to Sylvain Schmitz's work on static detection 6352 of potential ambiguities in GLR grammers. 6353 6354 2006-12-12 Joel E. Denny <jdenny (a] ces.clemson.edu> 6355 6356 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with 6357 `bison ', use m4_index instead of m4_substr since chopping up a string 6358 containing M4-special characters causes problems here. 6359 6360 Fix a couple of bugs related to special characters in user-specified 6361 file names, and make it easier for skeletons to compute output file 6362 names with the same file name prefix as Bison-computed output file 6363 names. 6364 * data/glr.cc, data/push.c, data/yacc.c: In @output, use 6365 b4_parser_file_name and b4_spec_defines_file instead of 6366 @output_parser_name@ and @output_header_name@, which are now redundant. 6367 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use 6368 b4_parser_file_name, b4_spec_defines_file, and the new 6369 @basename(FILENAME@) instead of @output_parser_name@ and 6370 @output_header_name@, which inappropriately escaped the file names as 6371 C string literals. 6372 * src/files.c (all_but_ext): Remove static qualifier. 6373 (compute_output_file_names): Move `free (all_but_ext)' to... 6374 (output_file_names_free): ... here since all_but_ext is needed later. 6375 * src/files.h (all_but_ext): Extern. 6376 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does 6377 exactly what MUSCLE_INSERT_STRING used to do. 6378 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special 6379 characters are escaped properly. 6380 * src/output.c (prepare): Define muscle file_name_all_but_ext as 6381 all_but_ext. 6382 For pkgdatadir muscle, maintain previous functionality by using 6383 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem 6384 is that b4_pkgdatadir is used inside m4_include in the skeletons, so 6385 digraphs would never be expanded. Hopefully no one has M4-special 6386 characters in his Bison installation path. 6387 * src/scan-skel.l: Don't parse @output_header_name@ and 6388 @output_parser_name@ anymore since they're now redundant. 6389 In @output, use decode_at_digraphs. 6390 Parse a new @basename command that invokes last_component. 6391 (decode_at_digraphs): New. 6392 (BASE_QPUTS): Remove unused. 6393 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro. 6394 (Output file name): New tests. 6395 6396 2006-12-09 Joel E. Denny <jdenny (a] ces.clemson.edu> 6397 6398 Warn about output files that are generated by the skeletons and that 6399 conflict with other output files. 6400 * data/glr.c: Don't generate the header file here when glr.cc does. 6401 * src/files.c (file_names, file_names_count): New static globals. 6402 (compute_output_file_names): Invoke output_file_name_check for files 6403 not generated by the skeletons and remove existing checks. 6404 (output_file_name_check): New function that warns about conflicting 6405 output file names. 6406 (output_file_names_free): Free file_names. 6407 * src/files.h (output_file_name_check): Declare. 6408 * src/scan-skel.l: Invoke output_file_name_check for files generated by 6409 the skeletons. 6410 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New. 6411 (Conflicting output files): New tests. 6412 6413 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues (a] gmx.de> 6414 6415 * doc/bison.texinfo: Fix a couple of typos. 6416 6417 2006-12-08 Bob Rossi <bob (a] brasko.net> 6418 6419 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse): 6420 Rename to... 6421 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and 6422 update all uses. 6423 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps. 6424 (yypush_parse): Rename yypvars argument to yyps and remove redundant 6425 local pv. 6426 (yypstate_init, yypush_parse): Declare in Bison-generated header file. 6427 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions. 6428 6429 2006-12-07 Bob Rossi <bob (a] brasko.net> 6430 and Joel Denny <jdenny (a] ces.clemson.edu> 6431 6432 * data/push.c (yypvarsinit): Change return type from void* to struct 6433 yypvars*.

All uses changed. 6582 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary 6583 values. 6584 (compute_file_name_parts, compute_output_file_names): Don't store 6585 read-only data in variables that will be freed. 6586 (compute_output_file_names): Free all_but_ext, all_but_tab_ext, 6587 src_extension, and header_extension. 6588 (output_file_names_free): New public function to free 6589 spec_verbose_file, spec_graph_file, spec_defines_file, 6590 parser_file_name, and dir_prefix. 6591 * src/getargs.c (getargs): Don't store read-only data in variables that 6592 will be freed. 6593 * src/main.c (main): Invoke output_file_names_free, code_scanner_free 6594 (which previously existed but was unused), and quotearg_free. 6595 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'. 6596 * src/muscle_tab.c: Likewise. 6597 (muscle_entry): Make the value char const *, 6598 and add a new storage member that is char * and can be freed. 6599 (muscle_entry_free): New private function. 6600 (muscle_init): Use it instead of free. 6601 (muscle_insert, muscle_grow): Update and use new storage member. 6602 (muscle_code_grow): Free the string passed to muscle_grow 6603 since it's not needed anymore. 6604 * src/parse-gram.y (%union): Make `chars' member a `char const *', and 6605 add a new `char *code' member. 6606 ("{...}"): Declare semantic type as code. 6607 * src/scan-code.h (translate_rule_action): 6608 (translate_symbol_action, translate_code, translate_action): Return 6609 `char const *' rather than `char *' since external code should not free 6610 these strings. 6611 * src/scan-code.l: Likewise. 6612 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE, 6613 which is "{...}" in the parser. 6614 * tests/Makefile.am (maintainer-check-valgrind): Set 6615 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking 6616 Valgrind. 6617 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't 6618 complain. 6619 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and 6620 expecting a non-zero exit status sets --leak-check=summary and 6621 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in 6622 this case, and we don't want to hear about it. 6623 6624 2006-11-08 Paul Eggert <eggert (a] cs.ucla.edu> 6625 6626 * bootstrap (runtime-po/Makevars): Derive from po/Makevars 6627 instead of from the template, to simplify configuration a bit. 6628 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4 6629 and m4/wint_t.m4, as they are needed with the latest gnulib. 6630 6631 2006-10-31 Joel E. Denny <jdenny (a] ces.clemson.edu> 6632 6633 Disable unset/unused mid-rule value warnings by default, and recognize 6634 --warnings=midrule-values to enable them. Discussed starting at 6635 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>. 6636 * NEWS (2.3a+): Mention. 6637 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum 6638 warnings): Add entry for midrule-values subargument. 6639 * src/reader.c (symbol_should_be_used): Don't return true just because 6640 the value is a set/used mid-rule value unless 6641 --warnings=midrule-values was specified. 6642 * tests/input.at (Unused values, Unused values before symbol 6643 declarations): Run tests with and without --warnings=midrule-values. 6644 6645 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather 6646 than LIST_FREE directly. 6647 6648 2006-10-31 Joel E. Denny <jdenny (a] ces.clemson.edu> 6649 6650 Finish implementing --warnings=error, which should not be implied by 6651 --warnings=all (or by its synonyms -W and --warnings without 6652 subarguments). 6653 * src/complain.c (set_warning_issued): New function to report that 6654 warnings are being treated as errors and to record an error if so. 6655 Invoke... 6656 (warn_at, warn): ... here. 6657 * src/getargs.c (warnings_args, warnings_types): Reorder so that 6658 "error - warnings are errors" does not appear above "all - all of the 6659 above". 6660 (getargs): For -W and --warnings without subarguments, don't let 6661 FLAGS_ARGMATCH set warnings_error in warnings_flag. 6662 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all. 6663 6664 2006-10-31 Joel E. Denny <jdenny (a] ces.clemson.edu> 6665 6666 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for 6667 empty subargument list. For example: `bison --warnings= parser.y'. 6668 6669 2006-10-21 Joel E. Denny <jdenny (a] ces.clemson.edu> 6670 6671 * data/push.c, data/yacc.c: Make sure there's a newline at the end of 6672 the parser header file so that gcc doesn't warn. 6673 6674 2006-10-21 Joel E. Denny <jdenny (a] ces.clemson.edu> 6675 6676 Split the default %destructor/%printer into two kinds: <*> and <!>. 6677 Discussed starting at 6678 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>. 6679 * NEWS (2.3a+): Mention. 6680 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the 6681 previous change today related to mid-rules. 6682 (Table of Symbols): Remove %symbol-default and add <*> and <!>. 6683 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove. 6684 (TYPE_TAG_ANY): Add as <*>. 6685 (TYPE_TAG_NONE): Add as <!>. 6686 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's 6687 for <*> and <!>. 6688 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove. 6689 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add. 6690 * src/symlist.c (symbol_list_default_new): Split into tagged and 6691 tagless versions. 6692 (symbol_list_destructor_set, symbol_list_printer_set): Split 6693 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and 6694 SYMLIST_DEFAULT_TAGLESS. 6695 * src/symlist.h: Update symbol_list_default*_new prototypes. 6696 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into 6697 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS. 6698 * src/symtab.c (default_destructor, default_destructor_location, 6699 default_printer, default_printer_location): Split each into tagged and 6700 tagless versions. 6701 (symbol_destructor_get, symbol_destructor_location_get, 6702 symbol_printer_get, symbol_printer_location_get): Implement tagged 6703 default and tagless default cases. 6704 (default_destructor_set, default_printer_set): Split each into tagged 6705 and tagless versions. 6706 * src/symtab.h: Update prototypes. 6707 * tests/actions.at (Default %printer and %destructor): Rename to... 6708 (Default tagless %printer and %destructor): ... this, and extend. 6709 (Per-type %printer and %destructor): Rename to... 6710 (Default tagged and per-type %printer and %destructor): ... this, and 6711 extend. 6712 (Default %printer and %destructor for user-defined end token): Extend. 6713 (Default %printer and %destructor are not for error or $undefined): 6714 Update. 6715 (Default %printer and %destructor are not for $accept): Update. 6716 (Default %printer and %destructor for mid-rule values): Extend. 6717 * tests/input.at (Default %printer and %destructor redeclared): Extend. 6718 (Unused values with default %destructor): Extend. 6719 6720 2006-10-21 Joel E. Denny <jdenny (a] ces.clemson.edu> 6721 6722 Don't apply the default %destructor/%printer to an unreferenced midrule 6723 value. Mentioned at 6724 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>. 6725 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially 6726 like $@n instead of just @n so that the default %destructor/%printer 6727 logic doesn't see them as user-defined symbols. 6728 (symbol_is_dummy): Check for both forms of the name. 6729 * src/reader.c (packgram): Remove the `$' from each midrule symbol 6730 name for which the midrule value is referenced in any action. 6731 * tests/actions.at (Default %printer and %destructor for mid-rule 6732 values): New test. 6733 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output 6734 for change to dummy symbol names. 6735 6736 2006-10-20 Joel E.

Describe usage less tersely. 7007 (CVS_only_file): New var. 7008 7009 2006-09-21 Paul Eggert <eggert (a] cs.ucla.edu> 7010 7011 * data/push.c (YYPUSH_MORE): Make it an enum instead. 7012 (yypushparse): Use YYPUSH_MORE instead of the mystery constant. 7013 Adjust white space and comments to match GNU style better. 7014 7015 2006-09-20 Bob Rossi <bob (a] brasko.net> 7016 7017 * data/push.c (yyresult_get): Remove function. 7018 (YYPUSH_MORE): Add #define. 7019 (yypushparse): Modify return value. 7020 7021 2006-09-20 Paul Eggert <eggert (a] cs.ucla.edu> 7022 7023 * stamp-h.in: Remove; no longer needed. 7024 * .cvsignore: Replace autom4te.cache and config.cache with *.cache. 7025 Remove config.h, config.hin, intl (no longer created). 7026 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h, 7027 stamp-h1. 7028 7029 Sync bootstrap from coreutils, as follows: 7030 7031 2006-09-18 Paul Eggert <eggert (a] cs.ucla.edu> 7032 7033 * bootstrap (symlink_to_gnulib): New function. 7034 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib 7035 to copies-of-gnulib. 7036 (cp_mark_as_generated, slurp, gnulib_files): 7037 Avoid making a copy if it's the same as the old version. 7038 (gnulib_files): Add support for this variable (used by Bison). 7039 7040 2006-09-20 Paul Eggert <eggert (a] cs.ucla.edu> 7041 7042 * src/getargs.c (usage): Rework to use conventions similar to 7043 coreutils, to make translation a bit easier and the code a bit 7044 smaller. Problem reported by Tim Van Holder. 7045 7046 2006-09-15 Paul Eggert <eggert (a] cs.ucla.edu> 7047 7048 Use some of gnulib's new modules, taken from coreutils. 7049 7050 * bootstrap: Sync from coreutils, except add support for gnulib_files. 7051 * bootstrap.conf: New file. 7052 (gnulib_modules): Add configmake, inttypes, unistd. 7053 (XGETTEXT_OPTIONS): Add complain, complain_at, 7054 fatal, fatal_at, warn, warn_at, unexpected_end. 7055 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here. 7056 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this. 7057 (gl_EARLY): Add. 7058 (AM_STDBOOL_H): Remove; gl_INIT now dows this. 7059 (gl_INIT): Add 7060 (GNULIB_AUTOCONF_SNIPPET): Remove. 7061 (AM_GNU_GETTEXT): Add; require formatstring macros since that's 7062 the pickiest. 7063 * lib/.cvsignore: Add inttypes_.h. 7064 * lib/Makefile.am: Include gnulib.mk first so we can append to it. 7065 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils. 7066 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove 7067 no-longer-necessary initializations. 7068 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES. 7069 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we 7070 use the unistd module. 7071 * src/system.h: Likewise. 7072 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4, 7073 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4, 7074 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4. 7075 * src/Makefile.am (DEFS): Remove, since configmake does this for us. 7076 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us. 7077 * src/system.h: Include inttypes.h unconditionally, now that we 7078 use the inttypes module. Don't bother to include stdint.h, since 7079 inttypes.h now does that for us. 7080 (LOCALEDIR): Remove, now that we use the configmake module. 7081 * src/getargs.c: Include configmake.h. 7082 * src/main.c: Likewise. 7083 * src/output.c: Likewise. 7084 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib, 7085 not from $abs_top_builddir, since config.h moved. 7086 7087 7088 Port to GCC 2.95. First two problems reported by Michael Deutschmann in 7089 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>. 7090 7091 * src/parse-gram.y (symbol_declaration): Don't put statements 7092 before declarations; it's not portable to C89. 7093 * src/scan-code.l (handle_action_at): Likewise. 7094 7095 * src/scan-code.l: Always initialize braces_level; the old code 7096 left it uninitialized and therefore had undefined behavior. 7097 7098 Don't attempt to redefine 'assert', since it runs afoul of 7099 systems where standard headers (mistakenly) include <assert.h>. 7100 Instead, define and use our own alternative, called 'aver'. 7101 * src/reader.c: Don't include assert.h, since we no longer 7102 use assert. 7103 * src/scan-code.l: Likewise. 7104 * src/system.h (assert): Remove, replacing with.... 7105 (aver): New function, taking a bool arg. All uses changed. 7106 * src/tables.c (pack_vector): Ensure that aver arg is bool, 7107 not merely an integer. 7108 7109 2006-09-15 Bob Rossi <bob (a] brasko.net> 7110 7111 Add support for push parsing. Based on the original work of 7112 Odd Arild Olsen <oao (a] fibula.no>. 7113 * data/Makefile.am (dist_pkgdata_DATA): Add push.c. 7114 * data/c.m4 (YYPUSH): New. 7115 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH. 7116 * data/push.c: New file. 7117 * src/getargs.c (push_parser): New var. 7118 * src/getargs.h (push_parser): New declaration. 7119 * src/output.c (prepare): Add macro insertion of `push_flag'. 7120 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token. 7121 (prologue_declaration): Parse %push-parser. 7122 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token. 7123 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to 7124 list of removed lines from the traces observed. 7125 (AT_CHECK_CALC_LALR): Added push parser tests. 7126 7127 2006-09-13 Paul Eggert <eggert (a] cs.ucla.edu> 7128 7129 * NEWS: Version 2.3a. 7130 * configure.ac (AC_INIT): Likewise. 7131 7132 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove 7133 "#define YYSTYPE int" that caused "make maintainer-check" to fail 7134 due to header ordering dependencies. I don't know why the #define 7135 was there. 7136 7137 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero 7138 runtime cost when YYDEBUG is not defined, and so that some tests 7139 that used to fail now work. Problem and initial suggestion by 7140 Paolo Bonzini. 7141 * data/c++.m4 (b4_parse_param_cons): Omit leading ','. 7142 * data/glr.cc (b4_parser_class_name): 7143 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_. 7144 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug. 7145 (yydebug_) [YYDEBUG]: New member. 7146 (yycdebug_): Now defined only if YYDEBUG. 7147 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG. 7148 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_. 7149 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only 7150 if YYYDEBUG. 7151 (debug_stream, set_debug_stream, debug_level, set_debug_level): 7152 Define only if YYDEBUG. 7153 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to 7154 set_debug_level. 7155 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise. 7156 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to 7157 AT_CHECK_CALC_GLR_CC that are working now. 7158 7159 2006-09-12 Paul Eggert <eggert (a] cs.ucla.edu> 7160 7161 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove. 7162 We don't need them in glr.cc, and glr.c defines them. 7163 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c 7164 assumes that defining it to anything is the same as defining 7165 it to 1. Problem reported by Paolo Bonzini. 7166 7167 2006-09-12 Paolo Bonzini <bonzini (a] gnu.org> (tiny change) 7168 7169 * data/c.m4 (b4_null, b4_case): Define. 7170 * src/output.c (prepare_symbols): Use b4_null. 7171 (user_actions_output): Use b4_case. 7172 7173 2006-09-11 Paul Eggert <eggert (a] cs.ucla.edu> 7174 7175 * data/glr.c (b4_shared_declarations): Put start-header first, 7176 before any #includes that we generate, so that feature-test 7177 macros work. Problem reported by Michael Deutschmann in 7178 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>. 7179 * data/lalr1.cc: Likewise. 7180 * doc/bison.texinfo (Prologue): Document that feature-test macros 7181 should be defined before any Bison declarations. 7182 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns 7183 that depend on location.hh after, not before, Bison decls, since 7184 we now include location.hh after the first user prologue. 7185 7186 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by 7187 Sander Brandenburg in 7188 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>. 7189 Also, fix minor white space and comment issues. 7190 (Prologue): Mention that it's better to define feature-test macros 7191 before Bison declarations. Problem reported by Michael Deutschmann. 7192 7193 * README-cvs: Fix typo: "&" should be "&&". Problem reported 7194 by Jim Meyering. 7195 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4. 7196 This adjusts to recent gnulib changes. 7197 7198 2006-09-04 Joel E. Denny <jdenny (a] ces.clemson.edu> 7199 7200 Finish implementation of per-type %destructor/%printer. Discussed 7201 starting at 7202 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html> 7203 and 7204 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>. 7205 * NEWS (2.3+): Add a description of this feature to the default 7206 %destructor/%printer description. 7207 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise. 7208 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set): 7209 Invoke semantic_type_destructor_set or semantic_type_printer_set when a 7210 list node contains a semantic type. 7211 * src/symtab.c, src/symtab.h: Extend with a table that associates 7212 semantic types with their %destructor's and %printer's. 7213 (semantic_type_from_uniqstr, semantic_type_get, 7214 semantic_type_destructor_set, semantic_type_printer_set): New functions 7215 composing the public interface of that table. 7216 (symbol_destructor_get, symbol_destructor_location_get, 7217 symbol_printer_get, symbol_printer_location_get): If there's no 7218 per-symbol %destructor/%printer, look up the per-type before trying 7219 the default. 7220 * tests/actions.at (Per-type %printer and %destructor): New test case. 7221 * tests/input.at (Default %printer and %destructor redeclared): 7222 Extend to check that multiple occurrences of %symbol-default in a 7223 single %destructor/%printer declaration is an error. 7224 (Per-type %printer and %destructor redeclared, Unused values with 7225 per-type %destructor): New test cases. 7226 7227 2006-09-04 Joel E. Denny <jdenny (a] ces.clemson.edu> 7228 7229 Require default %destructor/%printer to be declared using 7230 %symbol-default instead of an empty symbol list, and start working on 7231 new per-type %destructor/%printer. Discussed at 7232 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>. 7233 * NEWS (2.3+): Add %symbol-default to example. 7234 * bison.texinfo (Freeing Discarded Symbols): Likewise. 7235 (Table of Symbols): Add entry for %symbol-default. 7236 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token. 7237 (generic_symlist, generic_symlist_item): New nonterminals for creating 7238 a list in which each item is a symbol, semantic type, or 7239 %symbol-default. 7240 (grammar_declaration): Use generic_symlist in %destructor and %printer 7241 declarations instead of symbols.1 or an empty list. 7242 (symbol_declaration, precedence_declaration, symbols.1): Update actions 7243 for changes to symbol_list. 7244 * src/reader.c: Update for changes to symbol_list. 7245 * src/scan-code.l: Likewise. 7246 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token. 7247 * src/symlist.c, src/symlist.h: Extend such that a list node may 7248 represent a semantic type or a %symbol-default in addition to just an 7249 ordinary symbol. Add switched functions for setting %destructor's and 7250 %printer's. 7251 * tests/actions.at, tests/input.at: Add %symbol-default to all default 7252 %destructor/%printer declarations. 7253 7254 2006-08-23 Joel E. Denny <jdenny (a] ces.clemson.edu> 7255 7256 Whether the default %destructor/%printer applies to a particular symbol 7257 isn't a question of whether the user *declares* that symbol (in %token, 7258 for example). It's a question of whether the user by any means 7259 *defines* the symbol at all (by simply using a char token, for 7260 example). $end is defined by Bison whereas any other token with token 7261 number 0 is defined by the user. The error token is always defined by 7262 Bison regardless of whether the user declares it with %token, but we 7263 may one day let the user define error as a nonterminal instead. 7264 * NEWS (2.3+): Say "user-defined" instead of "user-declared". 7265 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document 7266 the meaning of "user-defined". 7267 * tests/actions.at (Default %printer and %destructor for user-declared 7268 end token): Rename to... 7269 (Default %printer and %destructor for user-defined end token): ... 7270 this. 7271 7272 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the 7273 computation of whether to apply the default, don't maintain a list of 7274 every Bison-defined symbol. Instead, just check for a first character 7275 of '$', which a user symbol cannot have, and check for the error token. 7276 7277 2006-08-21 Joel E. Denny <jdenny (a] ces.clemson.edu> 7278 7279 Don't apply the default %destructor or %printer to the error token, 7280 $undefined, or $accept. This change fits the general rule that the 7281 default %destructor and %printer are only for user-declared symbols, 7282 and it solves several difficulties that are described in the new test 7283 cases listed below. 7284 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement. 7285 * tests/actions.at (Default %printer and %destructor are not for error 7286 or $undefined, Default %printer and %destructor are not for $accept): 7287 New test cases. 7288 7289 2006-08-19 Joel E. Denny <jdenny (a] ces.clemson.edu> 7290 7291 Allow %start after the first rule. 7292 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol 7293 when parsing the first rule. 7294 (check_and_convert_grammar): Search for it here after all grammar 7295 declarations have been parsed. Skip midrules, which have dummy LHS 7296 nonterminals. 7297 * src/symtab.c (symbol_is_dummy): New function. 7298 * src/symtab.h (symbol_is_dummy): Declare it. 7299 * tests/input.at (%start after first rule): New test. 7300 7301 2006-08-18 Joel E. Denny <jdenny (a] ces.clemson.edu> 7302 7303 Redo some of the previous commit: add back the ability to use 7304 non-aliased/undeclared string literals since it might be useful to 7305 those declaring %token-table. 7306 * src/reader.c (check_and_convert_grammar): Undo changes in previous 7307 commit: don't worry about complaints from symbols_pack. 7308 * src/symtab.c (symbol_new, symbol_class_set, 7309 symbol_check_alias_consistency): Undo changes in previous commit: count 7310 each string literal as a new symbol and token, assign it a symbol 7311 number, and don't complain about non-aliased string literals. 7312 (symbols_pack): Since symbol_make_alias still does not decrement symbol 7313 and token counts but does still set aliased tokens to the same number, 7314 symbol_pack_processor now leaves empty slots in the symbols array. 7315 Remove those slots. 7316 * tests/regression.at (Undeclared string literal): Remove test case 7317 added in previous commit since non-aliased string literals are allowed 7318 again. 7319 (Characters Escapes, Web2c Actions): Undo changes in previous commit: 7320 remove unnecessary string literal declarations. 7321 * tests/sets.at (Firsts): Likewise. 7322 7323 2006-08-18 Joel E. Denny <jdenny (a] ces.clemson.edu> 7324 7325 Don't allow an undeclared string literal, but allow a string literal to 7326 be used before its declaration. 7327 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if 7328 symbols_pack complained. 7329 * src/symtab.c (symbol_new): Don't count a string literal as a new 7330 symbol. 7331 (symbol_class_set): Don't count a string literal as a new token, and 7332 don't assign it a symbol number since symbol_make_alias does that. 7333 (symbol_make_alias): It's not necessary to decrement the symbol and 7334 token counts anymore. Don't assume that an alias declaration occurs 7335 before any uses of the identifier or string, and thus don't assert that 7336 one of them has the highest symbol number so far. 7337 (symbol_check_alias_consistency): Complain if there's a string literal 7338 that wasn't declared as an alias. 7339 (symbols_pack): Bail if symbol_check_alias_consistency failed since 7340 symbol_pack asserts that every token has been assigned a symbol number 7341 although undeclared string literals have not. 7342 * tests/regression.at (String alias declared after use, Undeclared 7343 string literal): New test cases. 7344 (Characters Escapes, Web2c Actions): Declare string literals as 7345 aliases. 7346 * tests/sets.at (Firsts): Likewise. 7347 7348 2006-08-14 Joel E. Denny <jdenny (a] ces.clemson.edu> 7349 7350 In the grammar scanner, STRING_FINISH unclosed constructs and return 7351 them to the parser in order to improve error messages. 7352 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER, 7353 SC_BRACED_CODE, SC_PROLOGUE): Implement. 7354 * tests/input.at (Unclosed constructs): New test case. 7355 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is 7356 seen. 7357 7358 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove 7359 unused global. 7360 7361 2006-08-13 Joel E. Denny <jdenny (a] ces.clemson.edu> 7362 7363 Handle string aliases for character tokens correctly. 7364 * src/symtab.c (symbol_user_token_number_set): If the token has an 7365 alias, check and set its alias's user token number instead of its own, 7366 which is set to indicate the alias. Previously, every occurrence of 7367 the character token in the grammar overwrote that alias indicator with 7368 the character code. 7369 * tests/input.at (String aliases for character tokens): New test. 7370 7371 2006-08-12 Joel E. Denny <jdenny (a] ces.clemson.edu> 7372 7373 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts. 7374 7375 2006-08-11 Paul Eggert <eggert (a] cs.ucla.edu> 7376 7377 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT, 7378 to prevent failures when building on older platforms. 7379 Check for autopoint failure. 7380 Set XGETTEXT_OPTIONS to values that check for C format strings, 7381 so that translators are warned about them (this also helps 7382 prevent core dumps). 7383 7384 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer 7385 function, since it simplifies our code a bit. 7386 7387 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare 7388 rather than -W, so we don't get bogus warnings about sign comparisons. 7389 Add -Wpointer-arith, since that warning is useful (it reports code 7390 that does not conform to C89 and that some compilers reject). 7391 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change, 7392 since it's no longer needed. 7393 7394 2006-08-10 Joel E. Denny <jdenny (a] ces.clemson.edu> 7395 7396 Clean up scanners a bit. 7397 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack 7398 definitions so gcc won't warn when obstack_for_string is unused. 7399 * src/scan-code.l: config.h and system.h are already #include'd by 7400 scan-code-c.c, so get rid of them here. 7401 * src/scan-gram.l: Likewise. 7402 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack 7403 definitions rather than duplicating the rest of it. 7404 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h". 7405 7406 2006-08-09 Joel E. Denny <jdenny (a] ces.clemson.edu> 7407 7408 Suppress signed/unsigned comparison warnings for yycheck. 7409 * data/c.m4 (b4_safest_int_type): New macro. 7410 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against 7411 a signed int type, cast it to b4_safest_int_type first. 7412 * data/yacc.c: Likewise. 7413 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is 7414 also overwritten. 7415 7416 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues (a] gmx.de> (tiny change) 7417 7418 * doc/bison.texinfo: Fix some typos. 7419 7420 2006-08-02 Paul Eggert <eggert (a] cs.ucla.edu> 7421 7422 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4, 7423 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4. 7424 7425 * bootstrap (gnulib_tool): Stop using --assume-autoconf; 7426 the latest gnulib does this a different way. 7427 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms 7428 translation was patched, so stop omitting it. 7429 7430 2006-07-29 Joel E. Denny <jdenny (a] ces.clemson.edu> 7431 7432 Enable declaration of default %printer/%destructor. Make the parser 7433 use these for all user-declared grammar symbols for which the user does 7434 not declare a specific %printer/%destructor. Thus, the parser uses it 7435 for token 0 if the user declares it but not if Bison generates it as 7436 $end. Discussed starting at 7437 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>, 7438 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>, 7439 and 7440 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>. 7441 * NEWS (2.3+): Mention. 7442 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to 7443 declare a %destructor for a mid-rule's semantic value. It's just 7444 impossible to declare one specific to it. 7445 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor 7446 code. Describe default %destructor form. 7447 * src/parse-gram.y (grammar_declaration): Parse default 7448 %printer/%destructor declarations. 7449 * src/output.c (symbol_destructors_output): Use symbol_destructor_get 7450 and symbol_destructor_location_get rather than accessing the destructor 7451 and destructor_location members of struct symbol. 7452 (symbol_printers_output): Likewise but for %printer's. 7453 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's 7454 again. 7455 * src/symtab.c (default_destructor, default_destructor_location, 7456 default_printer, default_printer_location): New static global 7457 variables to record the default %destructor and %printer. 7458 (symbol_destructor_get, symbol_destructor_location_get, 7459 symbol_printer_get, symbol_printer_location_get): New functions to 7460 compute the appropriate %destructor and %printer for a symbol. 7461 (default_destructor_set, default_printer_set): New functions to set the 7462 default %destructor and %printer. 7463 * src/symtab.h: Prototype all those new functions. 7464 * tests/actions.at (Default %printer and %destructor): New test to 7465 check that the right %printer and %destructor are called, that they're 7466 not called for $end, and that $$ and @$ work correctly. 7467 (Default %printer and %destructor for user-declared end token): New 7468 test to check that the default %printer and %destructor are called for 7469 a user-declared end token. 7470 * tests/input.at (Default %printer and %destructor redeclared, Unused 7471 values with default %destructor): New tests to check related grammar 7472 warnings and errors. 7473 7474 2006-07-29 Joel E. Denny <jdenny (a] ces.clemson.edu> 7475 7476 Clean up handling of %destructor for the end token (token 0). 7477 Discussed starting at 7478 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html> 7479 and 7480 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>. 7481 7482 Make the skeletons consistent in how they pop the end token and invoke 7483 its %destructor. 7484 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start 7485 state, which has token number 0, since this would invoke the 7486 %destructor for the end token. 7487 * data/lalr1.cc (yy::parser::parse): Don't check for the final state 7488 until after shifting the end token, or else it won't be popped. 7489 * data/yacc.c (yyparse): Likewise. 7490 7491 * data/glr.c (yyparse): Clear the lookahead after shifting it even when 7492 it's the end token. Upon termination, destroy an unshifted lookahead 7493 even when it's the end token. 7494 * data/lalr1.cc (yy::parser::parse): Likewise. 7495 * data/yacc.c (yyparse): Likewise. 7496 7497 * src/reader.c (packgram): Don't check rule 0. This suppresses unused 7498 value warnings for the end token when the user gives the end token a 7499 %destructor. 7500 7501 * tests/actions.at (Printers and Destructors): Test all the above. 7502 7503 2006-07-24 Paul Eggert <eggert (a] cs.ucla.edu> 7504 7505 Update to latest gnulib and gettext versions. 7506 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer. 7507 Add fopen-safer. 7508 (gnulib_files): Add m4/warning.m4. Don't worry about files 7509 overwritten by autopoint. 7510 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4. 7511 Suppress "id", "ms", "tr" translations for now, since gettext 0.15 7512 rejects them. 7513 Don't use autoreconf; instead, invoke autopoint etc. by hand, 7514 so that we can remove the intl files at a better time. 7515 (intl_files_to_remove): Remove aclocal.m4, since it gets 7516 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4, 7517 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4, 7518 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4. 7519 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4. 7520 Remove datarootdir hack; no longer needed. 7521 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING. 7522 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15. 7523 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c, 7524 strdup.h. 7525 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4. 7526 * m4/warning.m4: Remove from CVS, since we now use gnulib's version. 7527 7528 2006-07-20 Paul Eggert <eggert (a] cs.ucla.edu> 7529 7530 * bootstrap: Adjust to today's change to gnulib-tool by invoking 7531 it with --assume-autoconf='latest-stable'. 7532 7533 2006-07-13 Joel E. Denny <jdenny (a] ces.clemson.edu> 7534 7535 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at 7536 least 1.4.7 and 1.4.4) by putting a #line between `typedef union 7537 YYSTYPE' and `{'. 7538 * src/muscle_tab.h (muscle_grow): Replace the header comments with 7539 those from muscle_tab.c since the old ones are misleading. 7540 7541 2006-07-13 Akim Demaille <akim (a] epita.fr> 7542 7543 Support %define "KEY" {VALUE}. 7544 * src/scan-code.h, src/scan-code.l (translate_action) 7545 (translate_rule_action, translate_symbol_action, translate_code): 7546 Return char *, not const char *. 7547 * src/parse-gram.y (declaration): Rename as... 7548 (prologue_declaration): this. 7549 (string_content): Remove this nonterminal, use STRING. 7550 (braceless, content, content.opt): New nonterminal. 7551 Use them. 7552 (%define): Now accept content.opt, i.e., accept also BRACED_CODE 7553 as value. 7554 * src/scan-gram.l (getargs.h): Don't include it. 7555 7556 2006-07-12 Paul Eggert <eggert (a] cs.ucla.edu> 7557 7558 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)' 7559 rather than a for-loop that declares a local bool variable. This 7560 should work around a compatibility problem with a Cray x1e C++ 7561 compiler reported by Hung Nguyen in 7562 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>. 7563 The for-loop was introduced in the 2004-11-17 change but I don't 7564 know why it was needed. 7565 7566 2006-07-12 Akim Demaille <akim (a] epita.fr> 7567 7568 * data/c.m4: Comment changes. 7569 7570 2006-07-10 Akim Demaille <akim (a] lrde.epita.fr> 7571 7572 * src/complain.c (error_message, ERROR_MESSAGE): New. 7573 To factor... 7574 (fatal_at, fatal, warn_at, warn, complain_at, complain): these. 7575 * src/complain.h, src/complain.c (warning_issued): Remove, unused. 7576 7577 2006-07-09 Paul Eggert <eggert (a] cs.ucla.edu> 7578 7579 * NEWS: Instead of %union, you can define and use your own union type 7580 YYSTYPE if your grammar contains at least one <type> tag. 7581 Your YYSTYPE need not be a macro; it can be a typedef. 7582 * doc/bison.texinfo (Value Type, Multiple Types, Location Type): 7583 (Union Decl, Decl Summary): Document this. 7584 * data/glr.c (YYSTYPE): Implement this. 7585 * data/glr.cc (YYSTYPE): Likewise. 7586 * data/lalr1.cc (YYSTYPE): Likewise. 7587 * data/yacc.c (YYSTYPE): Likewise. 7588 * src/output.c (prepare): Output tag_seen_flag. 7589 * src/parse-gram.y (declaration, grammar_declaration): 7590 Use 'union_seen' rather than 'typed' to determine whether 7591 %union has been seen, since grammars can now be typed without 7592 %union. 7593 (symbol_declaration, type.opt, symbol_def): 7594 Keep track of whether a tag has been seen. 7595 * src/reader.c (union_seen, tag_seen): New vars. 7596 (typed): remove. 7597 * src/reader.h (union_seen, tag_seen, typed): Likewise. 7598 * src/scan-code.l (untyped_var_seen): New variable. 7599 (handle_action_dollar): Adjust to above changes. 7600 (handle_action_dollar, handle_action_at): 7601 Improve overflow checking for outlandish numbers. 7602 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to 7603 avoid new diagnostics generated by above changes. 7604 * tests/regression.at (YYSTYPE typedef): Add test to check 7605 for type tags without %union. 7606 7607 * src/symlist.c (symbol_list_length): Return int, not unsigned 7608 int, since callers expect int. This may need to get revisited 7609 once we have proper integer overflow checking. 7610 7611 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this 7612 object is now static. 7613 7614 * src/getargs.c (flags_argmatch): Return void, not int, 7615 to pacify ./configure --enable-gcc-warnings. 7616 7617 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string) 7618 since last_string is already defined to FLEX_PREFIX (last_string). 7619 7620 2006-07-09 Akim Demaille <akim (a] lrde.epita.fr> 7621 7622 Implement --warnings/-W. 7623 * src/getargs.c (report_argmatch, trace_argmatch): Remove, 7624 replaced by... 7625 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro. 7626 Adjust callers. 7627 * src/getargs.h, src/getargs.c (warnings, warnings_flags) 7628 (warnings_args, warnings_types): New. 7629 (getargs, short_options, long_options): Accept -W/--warnings. 7630 Sort the options by alphabetical order, upper case letter right 7631 before its lower case. 7632 7633 2006-07-09 Joel E. Denny <jdenny (a] ces.clemson.edu> 7634 7635 Change %merge result type clash warnings to errors. Discussed at 7636 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>. 7637 * src/reader.c (record_merge_function_type): Use complain_at. 7638 * tests/glr-regression.at (Missed %merge type warnings when LHS type is 7639 declared later): Update test case results. 7640 7641 2006-07-09 Akim Demaille <akim (a] lrde.epita.fr> 7642 7643 * src/getargs.h, src/getargs.c: Swap --report and --trace handling 7644 to be in alphabetical order. 7645 (trace_args): Spelling fixes. 7646 7647 2006-07-09 Paul Eggert <eggert (a] cs.ucla.edu> 7648 7649 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy" 7650 so they don't collide with user-defined macros. 7651 (yy_stack_print): Don't assume that yytype_int16 promotes to int; 7652 this was never guaranteed, and now that we're using gnulib stdint, 7653 which defines int_fast16_t to long int, the problem is exposed. 7654 7655 2006-07-08 Paul Eggert <eggert (a] cs.ucla.edu> 7656 7657 * data/c.m4 (b4_basename): Simplify a bit, since we don't 7658 need the full POSIX semantics (and weren't implementing them 7659 anyway). 7660 7661 Adjust to Autoconf 2.60 and today's gnulib. 7662 * bootstrap (gnulib_modules): Add stdint. 7663 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool 7664 no longer copies it. 7665 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4, 7666 since stdint needs the former and wcwidth (which is now required 7667 by mbswidth) needs the latter. 7668 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to 7669 work around a compatibility glitch between gettext 0.14.6 and 7670 Autoconf 2.60. 7671 * configure.ac (AC_PREREQ): Require Autoconf 2.60. 7672 Do not check for uintptr_t, since new stdint module does the right 7673 thing. 7674 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h. 7675 Add stdint.h, stdint_.h, wcwidth.h. 7676 * m4/.cvsignore: Remove alloca.m4, onceonly.m4. 7677 Add absolute-header.m4, double-slash-root.m4, longlong.m4, 7678 stdint.m4, wchar_t.m4, wcwidth.m4. 7679 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the 7680 usual order for ../lib/*.h files. 7681 (file_name_split): Use last_component, not base_name, to adjust 7682 to gnulib changes. 7683 * src/parse-gram.h: Include <strverscmp.h> in the usual order 7684 for ../lib/*.h files. 7685 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8): 7686 Define unconditionally, since we now assume the stdint module. 7687 * src/scan-skel.l: Include <dirname.h>. 7688 (BASE_QPUTS): Use last_component, not base_name. 7689 * src/system.h: Include <unlocked-io.h> in the usual order 7690 for ../lib/*.h files. Include <stdint.h> unconditionally, 7691 since we now use the stdint module. 7692 (uintptr_t): Declare if UINTPTR_MAX is not defined, not 7693 HAVE_UINTPTR_T, since we now use the stdint module. 7694 (base_name): Remove decl, since files now include <dirname.h> 7695 to get the decl. 7696 7697 2006-07-08 Akim Demaille <akim (a] lrde.epita.fr> 7698 7699 * data/c.m4 (b4_location_initial_column, b4_location_initial_line): 7700 New, default to 1. 7701 * data/yacc.c, data/glr.c, data/location.cc: Use them. 7702 * NEWS, doc/bison.texinfo: The initial column and line are 1 by 7703 default. 7704 * tests/calc.at: Adjust. 7705 7706 2006-07-08 Akim Demaille <akim (a] lrde.epita.fr> 7707 7708 * data/c.m4 (b4_basename): New. 7709 (b4_syncline): Also output the location of its invocation (from 7710 the skeleton). 7711 (b4_user_action, b4_define_user_action, b4_user_actions) 7712 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header) 7713 (b4_user_stype): New. 7714 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them. 7715 7716 2006-07-07 Joel E. Denny <jdenny (a] ces.clemson.edu> 7717 7718 In the grammar file, the first column is 1 not 0 on the first line as 7719 on every other line. 7720 * src/parse-gram.y (%initial-action): Initialize @$ correctly. 7721 * tests/input.at (Torturing the Scanner): Update output. 7722 7723 * src/scan-gram.l (scanner_cursor): Declare it static. 7724 7725 2006-07-07 Joel E. Denny <jdenny (a] ces.clemson.edu> 7726 7727 In warnings, say "previous declaration" rather than "first 7728 declaration". 7729 * src/symtab.c (redeclaration): Do that here. 7730 * src/reader.c (record_merge_function_type): In the case of a result 7731 type clash, report the previous declaration rather than the very first 7732 one in the grammar file. 7733 * tests/glr-regression.at (Missed %merge type warnings when LHS type is 7734 declared later): Add a third declaration to check this behavior. 7735 * tests/input.at (Incompatible Aliases): Update output. 7736 7737 2006-06-27 Akim Demaille <akim (a] epita.fr> 7738 7739 * doc/Doxyfile.in: New. 7740 * doc/Makefile.am: Use it. 7741 * src/lalr.h, src/symtab.h: Initial doxygenation. 7742 7743 2006-06-26 Joel E. Denny <jdenny (a] ces.clemson.edu> 7744 7745 Don't miss %merge result type warnings just because the LHS types are 7746 declared after the %merge. This continues the effort of the previous 7747 patch. 7748 * src/reader.c (get_merge_function): Don't set the merger type yet. 7749 (record_merge_function_type): New function for setting the merger type 7750 and checking for clashes. 7751 (grammar_current_rule_merge_set): Set the location of the %merge for 7752 the current rule. 7753 (packgram): Invoke record_merge_function_type for each rule now that 7754 all symbol type declarations have been parsed. 7755 * src/reader.h (merger_list.type_declaration_location): New member 7756 storing the location of the first %merge from which the type for this 7757 merging function was derived. 7758 * src/symlist.h (symbol_list.merger_declaration_location): New member 7759 storing the location of a rule's %merge, if any. 7760 * tests/glr-regression.at (Missed %merge type warnings when LHS type is 7761 declared later): New test to catch the error fixed by the above patch. 7762 7763 2006-06-26 Joel E. Denny <jdenny (a] ces.clemson.edu> 7764 7765 Get action warnings (grammar_rule_check) right even when symbol 7766 declarations appear after the rules. Discussed at 7767 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html> 7768 and 7769 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>. 7770 Don't mistake the type of $$ in a midrule to be that of its parent 7771 rule's $$. 7772 * src/reader.c (grammar_current_rule_end): Don't invoke 7773 grammar_rule_check yet since not all symbol declarations may have been 7774 parsed yet. 7775 (grammar_midrule_action): Likewise. 7776 Don't record whether the midrule's $$ has been used yet since actions 7777 haven't been translated yet. 7778 Record the midrule's parent rule and its RHS index within the parent 7779 rule. 7780 (grammar_current_rule_action_append): Don't translate the action yet 7781 since not all symbol declarations may have been parsed yet and, thus, 7782 warnings about types for $$, $n, @$, and @n can't be reported yet. 7783 (packgram): Translate the action and invoke grammar_rule_check now that 7784 all symbol declarations have been parsed. 7785 * src/scan-code.l (handle_action_dollar): Now that this is invoked 7786 after parsing the entire grammar file, the symbol list here in the case 7787 of a midrule is actually the midrule's empty RHS, so reference its 7788 parent rule's RHS where necessary. 7789 On the other hand, now that you can already know it's a midrule, you 7790 aren't forced to think $$ has the same type as its parent rule's $$. 7791 (handle_action_at): In the case of a midrule, reference the parent rule 7792 where necessary. 7793 * src/symlist.c (symbol_list_new): Initialize new midrule-related 7794 members. 7795 (symbol_list_length): Now that this is invoked after all rules have 7796 been parsed, a NULL symbol (rather than a NULL symbol list node) 7797 terminates a rule. symbol_list_print already does this correctly. 7798 * src/symlist.h (symbol_list.midrule_parent_rule, 7799 symbol_list.midrule_parent_rhs_index): New members so that midrules can 7800 remember their relationships with their parents. 7801 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error 7802 fixed by the above patch. 7803 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros 7804 implementing... 7805 (Unused values): ... this old test case and... 7806 (Unused values before symbol declarations): ... this new test case. 7807 This one is the same as `Unused values' except that all symbol 7808 declarations appear after the rules in order to catch the rest of the 7809 errors fixed by the above patch. 7810 7811 2006-06-26 Joel E. Denny <jdenny (a] ces.clemson.edu> 7812 7813 More cleanup. 7814 * src/reader.c (current_rule): Declare it static since it's no longer 7815 used outside this file. 7816 (grammar_current_rule_action_append): Remove redundant arguments from 7817 translate_rule_action invocation. 7818 * src/reader.h (current_rule): Remove this unused extern. 7819 * src/scan-code.h (translate_rule_action): Remove redundant arguments. 7820 * src/scan-code.l (translate_rule_action): Likewise. 7821 7822 2006-06-25 Joel E. Denny <jdenny (a] ces.clemson.edu> 7823 7824 Clean up yesterday's patch. 7825 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here 7826 to... 7827 * src/reader.c (grammar_current_rule_action_append): ... here for 7828 consistency with grammar_current_rule_symbol_append. 7829 * tests/regression.at (Braced code in declaration in rules section): 7830 Make yyerror and yylex static as usual. 7831 7832 2006-06-24 Joel E. Denny <jdenny (a] ces.clemson.edu> 7833 7834 Fix bug that mistakes braced code in a declaration in the rules section 7835 to be a rule action. Mentioned at 7836 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>. 7837 * src/scan-gram.l: Move midrule action detection from the start of the 7838 scanning of any braced code to... 7839 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule 7840 action. For readability, use $2 and @2 rather than the equivalent 7841 global variables. 7842 * tests/regression.at (Braced code in declaration in rules section): 7843 New test to catch the error fixed by the above patch. 7844 7845 Work on code readability some. 7846 * src/scan-code.l (current_rule): Get rid of this misleading and 7847 redundant declaration: it's actually extern'ed in reader.h. 7848 (YY_DECL, code_lex, handle_action_dollar, handle_action_at, 7849 translate_action): Add a rule argument and use it instead of the global 7850 current_rule. 7851 (translate_rule_action): This already receives current_rule through an 7852 argument, so pass it on to translate_action instead of assigning 7853 current_rule to current_rule. 7854 (translate_symbol_action, translate_code): Pass rule = NULL to 7855 translate_action. 7856 7857 2006-06-23 Joel E. Denny <jdenny (a] ces.clemson.edu> 7858 7859 Rename %before-definitions to %start-header and %after-definitions to 7860 %end-header. Don't use these declarations to separate pre-prologue 7861 blocks from post-prologue blocks. Add new order-independent 7862 declarations %before-header and %after-header as alternatives to the 7863 traditional Yacc pre-prologue and post-prologue blocks. Discussed at 7864 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>. 7865 * NEWS (2.3+): Update for these changes. 7866 * data/glr.c (b4_before_definitions): Update to... 7867 (b4_start_header): ... this. 7868 (b4_after_definitions): Update to... 7869 (b4_end_header): ... this. 7870 * data/glr.cc: Likewise. 7871 * data/lalr1.cc: Likewise. 7872 * data/yacc.c: Likewise. 7873 * doc/bison.texinfo (The prologue): Update names, and replace remaining 7874 prologue blocks with %*-header declarations. 7875 (Calc++ Parser): Likewise. 7876 (Decl Summary): Update names. 7877 (Table of Symbols): Update description. 7878 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to... 7879 (PERCENT_END_HEADER): ... this. 7880 (PERCENT_BEFORE_DEFINITIONS): Update to... 7881 (PERCENT_START_HEADER): ... this. 7882 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens. 7883 (declaration): Update token names and m4 macro names. 7884 When parsing %end-header and %start-header, invoke translate_code 7885 before muscle_code_grow, and no longer set global booleans to remember 7886 whether these declarations have been seen. 7887 Parse new %after-header and %before-header. 7888 * src/reader.c (before_definitions, after_definitions): Remove. 7889 (prologue_augment): Accept a new bool argument to specify whether to 7890 augment the pre-prologue or post-prologue. 7891 * src/reader.h (before_definitions, after_definitions): Remove these 7892 extern's. 7893 (prologue_augment): Add new bool argument. 7894 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to... 7895 (PERCENT_END_HEADER): ... this. 7896 (PERCENT_BEFORE_DEFINITIONS): Update to... 7897 (PERCENT_START_HEADER): ... this. 7898 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens. 7899 * tests/actions.at (Printers and Destructors): Update names. 7900 7901 2006-06-22 Joel E. Denny <jdenny (a] ces.clemson.edu> 7902 7903 Add comparison operators for C++ location classes. Discussed at 7904 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>. 7905 * data/c++.m4 (b4_define_location_comparison): New boolean %define 7906 declaration indicating whether filename_type has an operator==. If 7907 filename_type is `std::string', it defaults to `1', `0' otherwise. 7908 * data/location.cc: Iff b4_define_location_comparison is `1', add 7909 operator== and operator!= for class position and for class location. 7910 7911 Some minor fixes. 7912 * src/scan-action.l: Remove unused file. 7913 * src/symtab.c (symbol_printer_set): Use printer_location not 7914 destructor_location. 7915 * src/symtab.h (struct symbol): Replace incorrect source comment for 7916 printer members. 7917 * tests/input.at (Incompatible Aliases): Update output with correct 7918 printer location. 7919 7920 2006-06-20 Joel E. Denny <jdenny (a] ces.clemson.edu> 7921 7922 Don't put the pre-prologue in the header file. For the yacc.c code 7923 file and the glr.c header and code files, move the pre-prologue before 7924 the token definitions. Add new %before-definitions and 7925 %after-definitions to declare code that will go in both the header file 7926 and code file. Discussed at 7927 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>, 7928 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>, 7929 and 7930 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>. 7931 * NEWS (2.3+): Describe these changes. 7932 * data/glr.c (b4_pre_prologue): Move from within to before... 7933 (b4_shared_declarations): ... this. 7934 Add new b4_before_definitions before b4_token_enums. 7935 Add new b4_after_definitions at the end. 7936 * data/glr.cc (b4_pre_prologue): Replace with... 7937 (b4_before_definitions): ... this in the header file. 7938 (b4_after_definitions): New near the end of the header file. 7939 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the 7940 code file right before including the header file. 7941 (b4_before_definitions): New in the previous position of 7942 b4_pre_prologue in the header file. 7943 (b4_after_definitions): New near the end of the header file. 7944 * data/yacc.c: Clean up some m4 quoting especially in the header file. 7945 (b4_token_enums_defines): In the code file, move to right before 7946 YYSTYPE for consistency with the header file. 7947 (b4_before_definitions): New right before b4_token_enums_defines in 7948 both the header and code file. 7949 (b4_after_definitions): New right after YYLTYPE and yylloc in both the 7950 header and code file. 7951 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead 7952 of prologues for %union dependencies. 7953 (Decl Summary): In %defines description, mention the effect of 7954 %before-definitions and %after-definitions on the header file. 7955 (Calc++ Parser): Forward declare driver in a %before-definitions rather 7956 than in the pre-prologue so that make check succeeds. 7957 (Table of Symbols): Add entries for %before-definitions and 7958 %after-definitions. 7959 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for 7960 %before-definitions. 7961 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions. 7962 (declaration): Parse those declarations and append to 7963 b4_before_definitions and b4_after_definitions, respectively. 7964 * src/reader.c (before_definitions, after_definitions): New bools to 7965 track whether those declarations have been seen. 7966 (prologue_augment): Add to the post-prologue if %union, 7967 %before-definitions, or %after-definitions has been seen. 7968 * src/reader.h (before_definitions, after_definitions): New extern's. 7969 * src/scan-gram.l: Scan the new declarations. 7970 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second 7971 prologue block in a %before-definitions or a %after-definitions based 7972 on whether the %union is declared. 7973 * tests/regression.at (Early token definitions with --yacc, Early token 7974 definitions without --yacc): Move tests for token definitions into the 7975 post-prologue since token names are no longer defined in the 7976 pre-prologue. 7977 7978 2006-06-20 Akim Demaille <akim (a] epita.fr> 7979 7980 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New. 7981 (symbol_get): Use it. 7982 * src/parse-gram.y: Use it. 7983 7984 2006-06-19 Joel E.

I haven't received any responses to my request 7999 for supporting the old way, or for documenting the new way. I 8000 have modified 'bootstrap' to use screen scraping 8001 (in this case, HTML scraping). This is unreliable and inelegant, 8002 but I don't see any better way. Yuck. 8003 * bootstrap (TP_URL, WGET_COMMAND): New vars. 8004 (get_translations): New function, which uses HTML scraping to 8005 deduce locations of latest translations. 8006 Use this function to grab both bison and bison-runtime .po files. 8007 Don't bother priming the pump for the runtime-po domain any more, 8008 as it's now translated better than bison is. 8009 8010 2006-06-19 Akim Demaille <akim (a] epita.fr> 8011 8012 * src/scan-gram.l: No longer "parse" things after `%union' until 8013 `{'. Rather, return a single "%union" token. 8014 No longer make symbols: return strings, and leave the conversion 8015 to symbols to the parser. 8016 (SC_PRE_CODE, token_type): Remove. 8017 * src/parse-gram.y (%union): New field `character'. 8018 Sort tokens. 8019 (CHAR): New token. 8020 (ID, ID_COLON): Now that the scanner no longer makes them 8021 identifiers, adjust all uses to invoke symbol_get. 8022 (id_colon): New, wraps the conversion from string to symbol. 8023 (%union): Accept a possible union_name. 8024 (symbol): Now can be a char. 8025 * data/c.m4 (b4_union_name): Leave a default value. 8026 * data/glr.c, data/yacc.c: Use it. 8027 8028 2006-06-11 Joel E. Denny <jdenny (a] ces.clemson.edu> 8029 8030 For associating token numbers with token names for "yacc.c", don't use 8031 #define statements unless `--yacc' is specified; always use enum 8032 yytokentype.

We can also split "composite tokens" back 8181 into simple tokens. 8182 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New. 8183 * src/scan-gram.l (add_column_width, adjust_location): Move to and 8184 rename as... 8185 * src/location.h, src/location.c (add_column_width) 8186 (location_compute): these. 8187 Fix the column count: the initial column is 0. 8188 (location_print): Be robust to ending column being 0. 8189 * src/location.h (boundary_set): New. 8190 * src/main.c: Adjust to scanner_free being renamed as 8191 gram_scanner_free. 8192 * src/output.c: Include scan-code.h. 8193 * src/parse-gram.y: Include scan-gram.h and scan-code.h. 8194 Use boundary_set. 8195 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION) 8196 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part, 8197 which is now, again, a separate token. 8198 Adjust all dependencies. 8199 Wherever actions with $ and @ are used, use translate_code. 8200 (action): Remove this nonterminal which is now useless. 8201 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h. 8202 (grammar_current_rule_action_append): Use translate_code. 8203 (packgram): Bound check ruleno, itemno, and rule_length. 8204 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor) 8205 (last_string, last_braced_code_loc, max_left_semantic_context) 8206 (scanner_initialize, scanner_free, scanner_last_string_free) 8207 (gram_out, gram_lineno, YY_DECL_): Move to... 8208 * src/scan-gram.h: this new file. 8209 (YY_DECL): Rename as... 8210 (GRAM_DECL): this. 8211 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New. 8212 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out): 8213 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in): 8214 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy): 8215 Move these declarations, and... 8216 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE): 8217 these to... 8218 * src/flex-scanner.h: this new file. 8219 * src/scan-gram.l (rule_length, rule_length_overflow) 8220 (increment_rule_length): Remove. 8221 (last_braced_code_loc): Rename as... 8222 (gram_last_braced_code_loc): this. 8223 Adjust to the changes of the parser. 8224 Move all the handling of $ and @ into... 8225 * src/scan-code.l: here. 8226 * src/scan-gram.l (handle_dollar, handle_at): Remove. 8227 (handle_action_dollar, handle_action_at): Move to... 8228 * src/scan-code.l: here. 8229 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h, 8230 scan-code.h, scan-code-c.c, scan-gram.h. 8231 (EXTRA_bison_SOURCES): Add scan-code.l. 8232 (BUILT_SOURCES): Add scan-code.c. 8233 (yacc): Be robust to white spaces. 8234 8235 * tests/conflicts.at, tests/input.at, tests/reduce.at, 8236 * tests/regression.at: Adjust the column numbers. 8237 * tests/regression.at: Adjust the error message. 8238 8239 2006-06-06 Joel E. Denny <jdenny (a] ces.clemson.edu> 8240 8241 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output. 8242 Use Akim's wording from 8243 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>. 8244 8245 2006-06-06 Joel E. Denny <jdenny (a] ces.clemson.edu> 8246 8247 Between Bison releases, manually append `+' to the previous Bison 8248 release number, and use that as a signal to automatically print the 8249 ChangeLog's CVS Id keyword from --version. Discussed starting at 8250 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>. 8251 * ChangeLog: Add Id header. 8252 * configure.ac (AC_INIT): Append `+' to `2.3'. 8253 * src/.cvsignore: Add revision.c. 8254 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h. 8255 (BUILT_SOURCES): Add revision.c. 8256 (revision.c): New target rule. This file defines a new global variable 8257 named revision. It initializes it with either the Id from ChangeLog 8258 or, if VERSION doesn't contain `+', with the empty string. 8259 * src/getargs.c (version): Print the value of revision. 8260 * src/revision.h: Extern revision. 8261 8262 2006-06-05 Paul Eggert <eggert (a] cs.ucla.edu> 8263 8264 * NEWS: Version 2.3. 8265 * configure.ac (AC_INIT): Likewise. 8266 8267 2006-05-30 Paul Eggert <eggert (a] cs.ucla.edu> 8268 8269 * data/glr.c (YYRECOVERING): Define to be a function-like macro 8270 with no arguments, not as an object-like macro. This is for 8271 compatibility with data/yacc.c. Problem reported by John P. Hartmann in 8272 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>. 8273 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols): 8274 Document this. 8275 8276 2006-05-30 Joel E. Denny <jdenny (a] ces.clemson.edu> 8277 8278 * src/getargs.c (usage): Back out yesterday's modification of the 8279 --help output so that we don't have to wait for translation before 8280 releasing 2.3. 8281 8282 2006-05-29 Paul Eggert <eggert (a] cs.ucla.edu> 8283 8284 * doc/bison.texinfo (Introduction): Don't say "GLR grammar". 8285 Problem reported by Akim Demaille. 8286 8287 2006-05-29 Joel E. Denny <jdenny (a] ces.clemson.edu> 8288 8289 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output. 8290 8291 2006-05-26 Paul Eggert <eggert (a] cs.ucla.edu> 8292 8293 * data/yacc.c (yy_reduce_print): Omit trailing white space in 8294 generated source code. Problem reported by Frans Englich in 8295 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>. 8296 8297 2006-05-22 Paul Eggert <eggert (a] cs.ucla.edu> 8298 8299 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the 8300 shell, not within 'make', so that 'make' by an ordinary builder 8301 (using GNU make) does not worry about configuring gzip. This also 8302 works around a bug reported independently by Keith Thompson and by 8303 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on 8304 stderr rather than stdout, messing up the build logs. 8305 8306 2006-05-21 Joel E. Denny <jdenny (a] ces.clemson.edu> 8307 8308 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID 8309 to make sure that YYID will never be unused. This fixes a 'make 8310 maintainer-check' failure caused by the recent changes to the 'Trivial 8311 grammars' test case, which caused g++ 4.1.0 to complain that YYID was 8312 not used. 8313 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case. 8314 8315 2006-05-21 Joel E. Denny <jdenny (a] ces.clemson.edu> 8316 8317 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the 8318 state before an empty RHS is always resolved here. Only the location 8319 of that state is guaranteed to be resolved, and that's enough. This 8320 fixes the remaining bug reported by Derek M. Jones in 8321 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>. 8322 * tests/glr-regression.at (Uninitialized location when reporting 8323 ambiguity): Test the above case. 8324 Also, the embedded comments in this test case claim it checks the case 8325 of an empty RHS that has inherited the initial location. However, the 8326 corresponding LHS was already resolved, so yyresolveLocations didn't 8327 actually have reason to modify it. Fix this by forcing 8328 nondeterministic operation at the beginning of the parse. 8329 8330 2006-05-20 Paul Eggert <eggert (a] cs.ucla.edu> 8331 8332 * data/c.m4 (b4_yy_symbol_print_generate): 8333 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than 8334 'const YYSTYPE', and similarly for YYLTYPE. This fixes one 8335 of the bugs reported today by Derek M Jones in 8336 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>. 8337 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be 8338 defined to be a type name without parens or brackets. 8339 (Location Type): Similarly for YYLTYPE. 8340 * tests/regression.at (Trivial grammars): Put in a test for this 8341 bug that will be caught by 'make maintainer-check' (though not, 8342 alas, by 'make check' unless your compiler is picky). 8343 8344 2006-05-19 Paul Eggert <eggert (a] cs.ucla.edu> 8345 8346 * NEWS: Version 2.2. 8347 * configure.ac (AC_INIT): Likewise. 8348 8349 2006-05-17 Joel E. Denny <jdenny (a] ces.clemson.edu> 8350 8351 * data/glr.c (yyreportTree): Make room in yystates for the state 8352 preceding the RHS. This fixes the segmentation fault reported by Derek 8353 M. Jones in 8354 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>. 8355 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing 8356 to the user. Reported for yyreportTree by Derek M. Jones later in the 8357 same thread. 8358 * THANKS: Add Derek M. Jones. 8359 Update my email address. 8360 Fix typo in Steve Murphy's name. 8361 8362 2006-05-14 Paul Eggert <eggert (a] cs.ucla.edu> 8363 8364 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in 8365 checking against YYLAST that caused the parser to miss a potential 8366 alternative in its diagnostic. 8367 Problem reported by Maria Jose Moron Fernandez in 8368 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>. 8369 * data/lalr1.cc (yysyntax_error_): Likewise. 8370 * data/yacc.c (yysyntax_error): Likewise. 8371 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for 8372 tokens, in case we run into an older C compiler. 8373 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros. 8374 Use them to check for the off-by-one error fixed above. 8375 8376 * data/yacc.c (yytnamerr): Fix typo: local var should be of type 8377 YYSIZE_T, not size_t. 8378 * tests/regression.at (Trivial grammars): New test, to catch 8379 the error fixed by the above patch. 8380 8381 2006-05-14 Akim Demaille <akim (a] lrde.epita.fr> 8382 8383 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming 8384 scheme. 8385 Reported by Steve Murphy. 8386 8387 2006-05-14 Akim Demaille <akim (a] lrde.epita.fr> 8388 8389 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory. 8390 * data/glr.cc: b4_location_flag is now b4_locations_flag. 8391 8392 2006-05-14 Akim Demaille <akim (a] lrde.epita.fr> 8393 8394 Implement --trace=m4. 8395 * src/getargs.c (trace_types, trace_args): Accept trace_m4. 8396 * src/output.c (output_skeleton): When set, pass -dV to m4. 8397 8398 Factor the handling of flags in m4. 8399 * src/output.c (prepare): Rename the muscle names debug, defines, 8400 error_verbose to debug_flag, defines_flag, error_verbose_flag. 8401 * data/c.m4: Adjust. 8402 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New. 8403 Use b4_define_flag_if to define other b4_FLAG_if macros. 8404 (b4_location_if): As a consequence, rename as... 8405 (b4_locations_if): this, for consistency. 8406 Adjust all the skeletons. 8407 8408 2006-05-14 Akim Demaille <akim (a] lrde.epita.fr> 8409 8410 * etc/bench.pm: Shorten bench names. 8411 8412 2006-05-14 Akim Demaille <akim (a] lrde.epita.fr> 8413 8414 * src/output.h, src/output.c (error_verbose): Move to... 8415 * src/getargs.h, src/getargs.c: here. 8416 Sort the flags. 8417 Adjust dependencies. 8418 8419 2006-05-13 Paul Eggert <eggert (a] cs.ucla.edu> 8420 8421 * data/c.m4 (b4_copyright): Put the special exception for Bison 8422 skeletons here, so we don't have to put it in each skeleton. All 8423 uses changed. Suggested by Akim Demaille. Also, wrap the 8424 copyright notice, in case it is longer than 80 columns. Replace 8425 comma by newline after title. 8426 8427 2006-05-11 Paul Eggert <eggert (a] cs.ucla.edu> 8428 8429 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an 8430 incompatibility, not a bug. Mention that it wasn't fixed as of 8431 flex 2.5.33. 8432 8433 2006-05-11 Akim Demaille <akim (a] lrde.epita.fr> 8434 8435 * examples/extexi: Enforce the precedence of concatenation over 8436 >>. 8437 Reported by Tommy Nordgren. 8438 8439 2006-05-11 Akim Demaille <akim (a] lrde.epita.fr> 8440 8441 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes 8442 with the member "token". 8443 Reported by Martin Nylin. 8444 8445 2006-05-08 Paul Eggert <eggert (a] cs.ucla.edu> 8446 8447 * data/glr.c: Switch to Bison 2.2 special-exception language in 8448 the copyright notice. Use more-regular format for titles and 8449 copyright notices. 8450 * data/glr.cc: Likewise. 8451 * data/location.cc: Likewise. 8452 * data/yacc.cc: Likewise. 8453 * doc/bison.texinfo (Conditions): Document this. 8454 * NEWS: likewise. Upgrade version to 2.2. 8455 8456 2006-04-27 Akim Demaille <akim (a] lrde.epita.fr> 8457 8458 * data/glr.cc: Remove dead code. 8459 8460 2006-04-25 Paul Eggert <eggert (a] cs.ucla.edu> 8461 8462 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use 8463 that variable and the line breaks the bootstrap. Problem reported 8464 by Juan M. Guerrero. 8465 8466 2006-04-24 Akim Demaille <akim (a] lrde.epita.fr> 8467 8468 * doc/bison.texinfo (Multiple start-symbols): New. 8469 8470 2006-04-24 Akim Demaille <akim (a] lrde.epita.fr> 8471 8472 * etc/README, etc/bench.pl: New. 8473 8474 2006-04-03 Akim Demaille <akim (a] lrde.epita.fr> 8475 8476 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any 8477 rule. 8478 Reported by Mickael Labau. 8479 * tests/input.at (Torturing the Scanner): Test it. 8480 8481 2006-03-16 Paul Eggert <eggert (a] cs.ucla.edu> 8482 8483 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice. 8484 Problem reported by Bob Rossi. 8485 8486 2006-03-13 Paul Eggert <eggert (a] cs.ucla.edu> 8487 8488 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used 8489 and didn't really work. 8490 For the index, use @ifnotinfo, not @iftex. 8491 Minor cleanups of spacing and terminology. 8492 8493 2006-03-12 Akim Demaille <akim (a] lrde.epita.fr> 8494 8495 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition 8496 of AT_NAME_PREFIX when %name-prefix is not used. 8497 8498 2006-03-12 Akim Demaille <akim (a] lrde.epita.fr> 8499 8500 Apply --prefix to C++ skeletons too: they change the namespace. 8501 The test suite already exercize these cases. 8502 * data/c++.m4 (b4_namespace): New. 8503 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'. 8504 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace. 8505 * data/yacc.c, data/glr.c: Remove a useless `[]'. 8506 * doc/bison.texinfo: Document it. 8507 (Option Cross Key): Use @multitable in all formats. It looks 8508 nicer, even in TeX outputs. 8509 (Rules): Use the same code whatever the output type is. 8510 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS) 8511 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX. 8512 * tests/calc.at: Use it, instead of hard coding `yy'. 8513 8514 2006-03-10 Akim Demaille <akim (a] lrde.epita.fr> 8515 8516 * TODO: Remove dead items. 8517 8518 2006-03-10 Akim Demaille <akim (a] lrde.epita.fr> 8519 8520 * doc/FAQ: Remove, merged into... 8521 * doc/bison.texinfo (FAQ): this. 8522 * doc/Makefile.am (EXTRA_DIST): Adjust. 8523 8524 2006-03-10 Akim Demaille <akim (a] lrde.epita.fr> 8525 8526 * data/c.m4 (b4_token_enum): Always define the enum of tokens, 8527 even if empty. 8528 * data/lalrl1.cc, data/glr.cc (parser::token_type): New. 8529 * doc/bison.texinfo (Calc++ Scanner): Use it. 8530 8531 2006-03-09 Paul Eggert <eggert (a] cs.ucla.edu> 8532 8533 Fix two nits reported by twlevo, plus one more that I discovered. 8534 8535 * src/assoc.h (assoc_to_string): Give a name to the arg, as 8536 this is the usual Bison style. 8537 * src/location.h (location_print): Likewise. 8538 8539 * src/reader.h (token_name): Likewise. 8540 8541 2006-03-08 Paul Eggert <eggert (a] cs.ucla.edu> 8542 8543 Fix some nits reported by twlevo. 8544 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure" 8545 and "POSIX". Use more-modern syntax for URLs. Mention C++ 8546 and ask for Java. Don't hardwire OS version numbers. Add 8547 copyright notice. 8548 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib. 8549 * src/conflicts.c (solved_conflicts_obstack): Now static. 8550 8551 2006-03-08 Joel E. Denny <jdenny (a] ces.clemson.edu> 8552 8553 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web 8554 page. Say "you can use it" not "you may use it" as on the web page; 8555 we're describing capabilities not granting permission. 8556 8557 2006-03-06 Paul Eggert <eggert (a] cs.ucla.edu> 8558 8559 * data/glr.c (yyresolveLocations): Rename local variables to avoid 8560 shadowing warnings. Use usual patter for iterating through RHS. 8561 * tests/glr-regression.at 8562 (Uninitialized location when reporting ambiguity): 8563 Modify yylex so that it uses its argument, rather than trying 8564 to rely on ARGSUSED (which doesn't work for gcc with warnings). 8565 const char -> char const. 8566 8567 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind): 8568 Don't use tabs inside commands; it messes up 'ps'. 8569 Problem reported by twlevo. 8570 8571 2006-03-06 Joel E. Denny <jdenny (a] ces.clemson.edu> 8572 8573 * tests/glr-regression.at (Uninitialized location when reporting 8574 ambiguity): New test case. 8575 * data/glr.c (yyresolveLocations): New function, which uses 8576 YYLLOC_DEFAULT. 8577 (yyresolveValue): Invoke yyresolveLocations before reporting an 8578 ambiguity. 8579 * doc/bison.texinfo (Default Action for Locations): Note 8580 YYLLOC_DEFAULT's usage for ambiguity locations. 8581 (GLR Semantic Actions): Cross-reference those notes. 8582 8583 2006-03-04 Joel E. Denny <jdenny (a] ces.clemson.edu> 8584 8585 * tests/glr-regression.at (Leaked semantic values when reporting 8586 ambiguity): Remove unnecessary union and type declarations. 8587 (Leaked lookahead after nondeterministic parse syntax error): New test 8588 case. 8589 * data/glr.c (yyparse): Check for zero stacks remaining before 8590 attempting to shift the lookahead so that you don't lose it. 8591 8592 2006-03-02 Joel E. Denny <jdenny (a] ces.clemson.edu> 8593 8594 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity. 8595 * tests/glr-regression.at (Leaked semantic values when reporting 8596 ambiguity): New test case. 8597 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return 8598 yyabort rather than invoking yyFail, which invokes longjmp. Remove the 8599 now unnecessary yystackp parameter. 8600 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary 8601 destructors can be called. 8602 8603 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily 8604 in existing testcases. 8605 8606 2006-03-02 Joel E. Denny <jdenny (a] ces.clemson.edu> 8607 8608 Don't leak semantic values for parent RHS when a user action cuts the 8609 parser, and clean up related code a bit. 8610 * tests/glr-regression.at (Leaked merged semantic value if user action 8611 cuts parse): Rename to... 8612 (Leaked semantic values if user action cuts parse): ... this. Add check 8613 for leaked parent RHS values. 8614 * data/glr.c (yydestroyGLRState): In debugging output, distinguish 8615 between an unresolved state (non-empty chain of semantic options) and 8616 an incomplete one (signaled by an empty chain). 8617 (yyresolveStates): Document the interface. Move all manipulation of a 8618 successfully or unsuccessfully resolved yyGLRState to... 8619 (yyresolveValue): ... here so that yyresolveValue always leaves a 8620 yyGLRState with consistent data and thus is easier to understand. 8621 Remove the yyvalp and yylocp parameters since they are always just 8622 taken from the yys parameter. When reporting a discarded merged value 8623 in debugging output, note that it is incompletely merged. Document the 8624 interface. 8625 (yyresolveAction): If resolving any of the RHS states fails, destroy 8626 them all rather than leaking them. Thus, as long as user actions are 8627 written to clean up the RHS correctly, yyresolveAction always cleans up 8628 the RHS of a semantic option. Document the interface. 8629 8630 2006-02-27 Paul Eggert <eggert (a] cs.ucla.edu> 8631 8632 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that 8633 led to a segmentation fault in GNU Pascal. Problem reported 8634 by Waldek Hebisch. 8635 8636 2006-02-21 Joel E. Denny <jdenny (a] ces.clemson.edu> 8637 8638 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a 8639 mid-rule action inside a nonterminal symbol in order to declare a 8640 destructor for its semantic value. 8641 8642 2006-02-16 Paul Eggert <eggert (a] cs.ucla.edu> 8643 8644 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && ! 8645 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined 8646 __cplusplus && ! defined _STDLIB_H && ! 8647 ((defined YYMALLOC || defined malloc) && (defined YYFREE || 8648 defined free))]: Include <stdlib.h> rather than rolling our own 8649 declarations of malloc and free, to avoid problems with 8650 incompatible declarations (using 'throw') C++'s stdlib.h. This 8651 should fix Debian bug 340012 8652 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>, 8653 reported by Guillaume Melquiond. 8654 8655 2006-02-13 Paul Eggert <eggert (a] cs.ucla.edu> 8656 8657 * NEWS: Clarify symbols versus types in unused-value warnings. 8658 8659 * configure.ac (AC_INIT): Bump version number. 8660 8661 2006-02-13 Paul Eggert <eggert (a] cs.ucla.edu> 8662 8663 * NEWS: Version 2.1a. 8664 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex, 8665 since C99 requires this. 8666 8667 2006-02-11 Paul Eggert <eggert (a] cs.ucla.edu> 8668 8669 * m4/c-working.m4: New file. 8670 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it. 8671 8672 2006-02-10 Paul Eggert <eggert (a] cs.ucla.edu> 8673 8674 * Makefile.maint: Merge from coreutils. 8675 8676 2006-02-09 Paul Eggert <eggert (a] cs.ucla.edu> 8677 8678 More portability fixes for problems summarized by Nelson H. F. Beebe. 8679 8680 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a 8681 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89 8682 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC 8683 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this 8684 messes up because C++ code is compiled in 32-bit mode but linked 8685 in 64-bit mode. 8686 8687 2006-02-08 Paul Eggert <eggert (a] cs.ucla.edu> 8688 8689 More portability fixes for problems summarized by Nelson H.

This resembles the 2005-10-10 patch to src/scan-skel.l. 8693 8694 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from 8695 nodist_PROGRAMS, since we don't need to actually compile the 8696 example if we're just doing a plain 'make'. This avoids bothering 8697 the installer unnecessarily about problems due to weird C++ 8698 compilers. 8699 8700 2006-02-06 Paul Eggert <eggert (a] cs.ucla.edu> 8701 8702 More portability fixes for problems summarized by Nelson H. F. Beebe. 8703 8704 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather 8705 than #include "...", and compile with -I'.'. The old method was 8706 not portable, according to Posix and the C standard, and it does 8707 not work with Sun C 5.7, where previous #line directives affect 8708 the working directory used in later #include "..." directives. 8709 8710 2006-02-06 Juan Manuel Guerrero <juan.guerrero (a] gmx.de> 8711 8712 Various DJGGP specific issues in /djgpp 8713 8714 2006-02-02 Paul Eggert <eggert (a] cs.ucla.edu> 8715 8716 More portability fixes for problems summarized by Nelson H.

This works 8737 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a 8738 random system header somewhere that includes the equivalent of 8739 <iso646.h>. 8740 8741 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC 8742 -E" works; it apparently doesn't work with PathScale EKO Compiler 8743 Suite Version 2.0. 8744 8745 2006-01-30 Joel E. Denny <jdenny (a] ces.clemson.edu> 8746 8747 During deterministic GLR operation, user actions should be able to 8748 influence the parse by changing yychar. To make this easier to fix and 8749 to make glr.c easier to evolve in general, don't maintain yytoken in 8750 parallel with yychar; just compute yytoken when needed. 8751 * tests/glr-regression.at (Incorrect lookahead during deterministic 8752 GLR): Check that setting yychar in a user action has the intended 8753 effect. 8754 * data/glr.c (yyGLRStack): Remove yytokenp member. 8755 (yyclearin): Don't set *yytokenp. 8756 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine 8757 yychar rather than *yytokenp to determine the current lookahead. 8758 Compute yytoken locally when needed. 8759 (yyparse): Likewise. Remove the local yytoken that yytokenp used to 8760 point to. 8761 8762 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment 8763 after `--report' documentation. 8764 8765 2006-01-30 Paul Eggert <eggert (a] cs.ucla.edu> 8766 8767 * src/parse-gram.y (grammar_declaration): Location of printer 8768 symbol is @1, not list->location. Bug reported by twlevo. 8769 * tests/input.at (Incompatible Aliases): Adjust to above change. 8770 8771 2006-01-29 Paul Eggert <eggert (a] cs.ucla.edu> 8772 8773 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do 8774 all the test at once. This makes the output easier to read in the 8775 normal case. 8776 8777 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I 8778 got from <http://bro-ids.org/download.html>. The bug is that 8779 when two actions appeared in succession, the second one was 8780 scanned before the first one was added to the grammar rule 8781 as a midrule action. Bison then output the incorrect warning 8782 "parse.y:905.17-906.36: warning: unused value: $3". 8783 * src/parse-gram.y (BRACED_CODE, action): These are no longer 8784 associated with a value. 8785 (rhs): Don't invoke grammar_current_rule_action_append. 8786 (action): Invoke it here instead. 8787 * src/reader.c (grammar_midrule_action): Now extern. 8788 (grammar_current_rule_action_append): Don't invoke 8789 grammar_midrule_action; that is now the scanner's job. 8790 * src/reader.h (last_string, last_braced_code_loc): 8791 (grammar_midrule_action): New decls. 8792 * src/scan-gram.l (last_string): Now extern, sigh. 8793 (last_braced_code_loc): New extern variable. 8794 (<INITIAL>"{"): Invoke grammar_midrule_action if the current 8795 rule already has an action. 8796 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning. 8797 * tests/input.at (AT_CHECK_UNUSED_VALUES): 8798 Add some tests to check that the above changes fixed the bug. 8799 8800 2006-01-27 Paul Eggert <eggert (a] cs.ucla.edu> 8801 8802 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p. 8803 All used changed. Check whether the symbol has a destructor, 8804 not whether it is typed. 8805 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so 8806 that the values are still reported as unused. All line numbers 8807 adjusted. 8808 8809 2006-01-23 Paul Eggert <eggert (a] cs.ucla.edu> 8810 8811 Work around a bug in bro 0.8, which underparenthesizes its 8812 definition of YYLLOC_DEFAULT. 8813 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize 8814 their arguments. 8815 * data/lalr1.cc: Likewise. 8816 * data/yacc.cc: Likewise. 8817 8818 2006-01-22 Paul Eggert <eggert (a] cs.ucla.edu> 8819 8820 Work around a bug in Pike 7.0, and give the Pike folks a 8821 better way to override the usual int widths. 8822 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the 8823 user can override the types. 8824 (short): #undef, to work around a bug in Pike 7.0. 8825 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types. 8826 (union yyalloc.yyss): Use yytype_int16 rather than short. 8827 All uses changed. 8828 (yysigned_char): Remove. 8829 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16): 8830 (YYTYPE_INT16): New macros, to test the new facility in yacc.c. 8831 * tests/regression.at (Web2c Actions): Adjust to above changes. 8832 8833 * src/reader.c (check_and_convert_grammar): New function. 8834 (reader): Close the input file even if something went wrong during 8835 parsing. Minor file descriptor leak reported by twlevo. 8836 8837 * src/assoc.c (assoc_to_string): Use a default: abort (); case 8838 to pacify gcc -Wswitch-default. 8839 * src/scan-gram.l (adjust_location): Use a default: break;

Denny <jdenny (a] ces.clemson.edu> 9037 9038 * doc/bison.texinfo: Fix some typos. 9039 (GLR Semantic Actions): New subsection discussing special 9040 considerations because GLR semantic actions might be deferred. 9041 (Actions): Mention look-ahead usage of yylval. 9042 (Actions and Locations): Mention look-ahead usage of yylloc. 9043 (Special Features for Use in Actions): Add YYEOF entry and mention it 9044 in the yychar entry. 9045 In the yychar entry, remove mention of the local yychar case (pure 9046 parser) since this is irrelevant information when writing semantic 9047 actions and since it's already discussed in `Table of Symbols' where 9048 yychar is otherwise described as an external variable. 9049 In the yychar entry, don't call it the `current' look-ahead since it 9050 isn't when semantic actions are deferred. 9051 In the yychar and yyclearin entries, add note about deferred semantic 9052 actions. 9053 Add yylloc and yylval entries discussing look-ahead usage. 9054 (Look-Ahead Tokens): When discussing yychar, don't call it the 9055 `current' look-ahead, and do mention yylval and yylloc. 9056 (Error Recovery): Cross-reference `Action Features' when mentioning 9057 yyclearin. 9058 (Table of Symbols): In the yychar entry, don't call it the `current' 9059 look-ahead. 9060 In the yylloc and yylval entries, mention look-ahead usage. 9061 9062 2006-01-08 Joel E. Denny <jdenny (a] ces.clemson.edu> 9063 9064 * tests/glr-regression.at: Update copyright year to 2006. 9065 9066 2006-01-06 Joel E. Denny <jdenny (a] ces.clemson.edu> 9067 9068 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to 9069 use during nondeterministic operation to track which stacks have 9070 actually needed the current lookahead. 9071 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack): 9072 Allocate, deallocate, resize, and otherwise shuffle space for 9073 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet. 9074 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status 9075 appropriately during nondeterministic operation. 9076 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc 9077 members to store the current lookahead to be used by the deferred 9078 user action. 9079 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack 9080 from which the RHS is taken. Set the lookahead members of the new 9081 yySemanticOption according to the lookahead status for stack yyk. 9082 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to 9083 yyaddDeferredAction. 9084 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead 9085 members of yySemanticOption before invoking yyuserAction, and then set 9086 them back to their current values afterward. 9087 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY. 9088 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint. 9089 * tests/glr-regression.at: Remove `.' from the ends of recent test case 9090 titles for consistency. 9091 (Leaked merged semantic value if user action cuts parse): In order to 9092 suppress lint warnings, use arguments in merge function, and assign 9093 char value < 128 in main. 9094 (Incorrect lookahead during deterministic GLR): New test case. 9095 (Incorrect lookahead during nondeterministic GLR): New test case. 9096 9097 2006-01-06 Joel E. Denny <jdenny (a] ces.clemson.edu> 9098 9099 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept 9100 !yyvaluep as signal that no semantic value is available to print. 9101 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try 9102 to print a semantic value. 9103 9104 2006-01-06 Joel E. Denny <jdenny (a] ces.clemson.edu> 9105 9106 * tests/glr-regression.at: For consistency with my newer test cases, 9107 don't thank myself. 9108 9109 2006-01-05 Joel E. Denny <jdenny (a] ces.clemson.edu> 9110 9111 * data/glr.c (yyresolveValue): When merging semantic options, if at 9112 least one user action succeeds but a later one cuts the parse, then 9113 destroy the semantic value before returning rather than leaking it. 9114 (yyresolveStates): If a user action cuts the parse and thus 9115 yyresolveValue fails, ignore the (unset) semantic value rather than 9116 corrupting the yyGLRState, and empty the semantic options list since 9117 the user actions should have called all necessary destructors. 9118 Simplify code with YYCHK. 9119 * tests/glr-regression.at (Corrupted semantic options if user action 9120 cuts parse): New test case. 9121 (Undesirable destructors if user action cuts parse): New test case. 9122 Before applying any of this patch, this test case never actually failed 9123 for me... but only because the corrupted semantic options usually 9124 masked this bug. 9125 (Leaked merged semantic value if user action cuts parse): New test 9126 case. 9127 9128 2006-01-05 Akim Demaille <akim (a] epita.fr> 9129 9130 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/. 9131 9132 2006-01-04 Paul Eggert <eggert (a] cs.ucla.edu> 9133 9134 * data/c.m4 (b4_c_modern): New macro, with a new provision for 9135 _MSC_VER.

Currently 10063 skipped. It fails on my host but I'm not sure it'll always fail. 10064 10065 2005-09-16 Akim Demaille <akim (a] epita.fr> 10066 10067 * src/symtab.h (struct symbol): Declare the printer and destructor 10068 as const, to avoid accidental calls to free. 10069 (symbol_destructor_set, symbol_printer_set): Adjust. 10070 * src/symtab.c: Adjust. 10071 10072 2005-09-16 Akim Demaille <akim (a] epita.fr> 10073 10074 * data/c.m4 (b4_token_enums): New. 10075 (b4_token_defines): Rename as... 10076 (b4_token_enums_defines): this. 10077 (b4_token_defines): New, output only the #defines. 10078 * data/yacc.c, data/glr.c: Adjust. 10079 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines. 10080 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define 10081 as default values. 10082 10083 2005-09-16 Akim Demaille <akim (a] epita.fr> 10084 10085 * data/lalr1.cc (yylex_): Remove, inline its code. 10086 (yyreport_syntax_error_): Remove, replaced by... 10087 (yysyntax_error_): this which returns a string and leaves to the 10088 caller the call to the users' error function. 10089 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc): 10090 Move from members of the parser object... 10091 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc): 10092 to local variables of the parse function. 10093 10094 2005-09-16 Akim Demaille <akim (a] epita.fr> 10095 10096 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF 10097 since it's in Bison's name space. 10098 10099 2005-09-15 Paul Eggert <eggert (a] cs.ucla.edu> 10100 10101 * data/glr.c (yyresolveValue): Add default case to pacify 10102 gcc -Wswitch-default.

It currently 10251 uses 'echo', and 'echo' isn't portable if its argument contains 10252 backslashes. Problem found on OpenBSD 3.4. Also, do not assume 10253 that the byte '\0xff' is not printable in the C locale; it is, 10254 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are 10255 not printable, so use '\0x81' to test. 10256 10257 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent 10258 version of GCC, since the macro is used with non-GCC compilers. 10259 10260 Fix core dump reported by Pablo De Napoli in 10261 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>. 10262 * tests/regression.at (Invalid inputs with {}): New test. 10263 * src/parse-gram.y (token_name): Translate type before using 10264 it as an index. 10265 10266 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on 10267 the user's name space. All uses changed to __attribute__ 10268 ((__unused__)). 10269 (yyFail, yyMemoryExhausted, yyreportAmbiguity): 10270 Add __attribute__ ((__noreturn__)). 10271 10272 * etc/clcommit: Remove. We weren't using it, and it failed 10273 "make maintainer-distcheck". 10274 * Makefile.maint: Merge from coreutils. 10275 (CVS_LIST, CVS_LIST_EXCEPT): New macros. 10276 (syntax-check-rules): Change list of rules as described below. 10277 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length): 10278 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof): 10279 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope): 10280 (sc_trailing_space): New rules. 10281 (sc_xalloc_h_in_src): Remove. 10282 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value): 10283 (sc_space_tab, sc_error_exit_success, sc_changelog): 10284 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics): 10285 (makefile-check, po-check, author_mark_check): 10286 (makefile_path_separator_check, copyright-check): 10287 Use grep -n, to make it easier to find violations. 10288 Use CVS_LIST and CVS_LIST_EXCEPT. 10289 (header_regexp, h_re): Remove. 10290 (dd_c): New macro. 10291 (sc_dd_max_sym_length, .re-list, news-date-check): New rules. 10292 (my-distcheck): Use more-modern GCC flags. 10293 (signatures, %.asc): Remove. 10294 (rel-files, announcement): Remove signatures. 10295 Restore old updating code, even though we don't use it, so 10296 that we're the same as coreutils. 10297 (alpha, beta, major): Depend on news-date-check. 10298 Make the upload commands. 10299 10300 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space. 10301 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise. 10302 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise. 10303 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise. 10304 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise. 10305 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise. 10306 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise. 10307 * tests/sets.at: Likewise. 10308 10309 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that 10310 we comment out the Autoconf version number. 10311 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as 10312 it's error-prone and "make maintainer-distcheck" rejects it. 10313 10314 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H. 10315 Indent calls to "error" to pacify "make maintainer-distcheck", 10316 when the calls are not intended to be translated. 10317 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h. 10318 10319 * src/Makefile.am (DEFS): Use +=, to pacify 10320 "make maintainer-distcheck". 10321 (bison_SOURCES): Add scan-skel.h. 10322 (sc_tight_scope): New rule, from coreutils. 10323 10324 * src/files.c (src_extension, header_extension): 10325 Now static, not extern. 10326 * src/getargs.c (short_options): Likewise. 10327 * src/muscle_tab.c (muscle_table): Likewise. 10328 * src/parse-gram.y (current_class, current_type, current_prec): 10329 Likewise. 10330 * src/reader.c (grammar_end, previous_rule_end): Likewise. 10331 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck". 10332 * src/main.c (main): Cast bindtextdomain and textdomain calls to 10333 void, to avoid warning when NLS is disabled. 10334 * src/output.c: Include scan-skel.h. 10335 (scan_skel): Remove decl, since scan-skel.h does this. 10336 (output_skeleton): 10337 Indent calls to "error" to pacify "make maintainer-distcheck". 10338 * src/print_graph.c: Don't include <obstack.h>, as system.h does this. 10339 * src/reader.h (gram_end, gram_lineno): New decls to pacify 10340 "make maintainer-distcheck". 10341 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in): 10342 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno): 10343 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug): 10344 (skel_lex_destroy, scan_skel): Move these decls to... 10345 * src/scan-skel.h: New file. 10346 * src/uniqstr.c (uniqstr_assert): 10347 Indent calls to "error" to pacify "make maintainer-distcheck". 10348 10349 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR), 10350 not @VAR@. 10351 10352 * tests/torture.at: Revamp to avoid misuse of atoi that 10353 "make maintainer-distcheck" complained about. 10354 10355 * examples/extexi (message): Don't print a message more than once, 10356 and omit line-number decoration that makes Emacs compile think 10357 that informative messages are worth worrying about. 10358 10359 2005-07-22 Paul Eggert <eggert (a] cs.ucla.edu> 10360 10361 * configure.ac: Update version number. 10362 10363 * Makefile.am (SUBDIRS): Add examples; somehow this got removed 10364 accidentally. 10365 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's 10366 autogenerated by the maintainer. 10367 * examples/calc++/.cvsignore: Add *.yy. 10368 10369 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result. 10370 * lib/bitset_stats.c (bitset_stats_init): Likewise. 10371 * lib/bitsetv.c (bitsetv_alloc): Likewise. 10372 10373 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c. 10374 10375 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint 10376 from maintainer-distcheck about casting the argument of 'free'. 10377 10378 * NEWS: Mention recent yytname changes. 10379 * THANKS: Add Anthony Heading, twlevo (a] xs4all.nl. 10380 10381 * bootstrap: For translations that have not yet been upgraded to 10382 the new runtime-po domain, prime the pump by extracting the 10383 relevant strings from the obsolete translations. This code can be 10384 removed once the bison-runtime domain has been translated by each 10385 team. 10386 10387 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names, 10388 now that token names are already quoted. 10389 10390 Fix problem reported by Anthony Heading. 10391 * data/glr.c (YYTOKEN_TABLE): New macro. 10392 (yytname): Define if YYTOKEN_TABLE. 10393 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise. 10394 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise. 10395 (YYERROR_VERBOSE): Define the same way the other skeletons do. 10396 * src/output.c (prepare_symbols): Output token_table_flag. 10397 10398 2005-07-21 Paul Eggert <eggert (a] cs.ucla.edu> 10399 10400 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc 10401 again if the first call fails. 10402 10403 * data/glr.c (yytnamerr): New function. 10404 (yyreportSyntaxError): Use it to dequote most string literals. 10405 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility 10406 with other skeletons. All uses changed. 10407 (yytnameerr_): New function. 10408 (yyreport_syntax_error): Use it to dequote most string literals. 10409 * data/yacc.c (yytnamerr): New function. 10410 (yyerrlab): Use it to decode most string literals. 10411 * doc/bison.texinfo (Decl Summary, Calling Convention): 10412 Clarify quoting convention of yytname. 10413 * src/output.c (prepare_symbols): Quote all names. This undoes 10414 the 2005-04-17 change, which is now accomplished (mostly) via 10415 changes in the parsers as described above. 10416 * tests/regression.at (Token definitions, Web2c Actions): 10417 Undo most 2005-04-17 change here, too. 10418 10419 2005-07-20 Paul Eggert <eggert (a] cs.ucla.edu> 10420 10421 Fix more problems reported by twlevo (a] xs4all.nl. 10422 * tests/cxx-type.at: Don't pipe output of ./types through sed to 10423 remove trailing spaces. This loses the exit status of ./types, 10424 and isn't needed since ./types shouldn't be emitting trailing 10425 spaces. 10426 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed, 10427 as the stack isn't valid in that case. 10428 10429 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out): 10430 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in): 10431 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy): 10432 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31 10433 is used. 10434 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out): 10435 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in): 10436 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy): 10437 Likewise. 10438 10439 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with 10440 overly-picky compilers that reject 'char *foo = "bar";'. 10441 10442 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output 10443 to FILE * parameter, not to stderr. This fixes a typo introduced 10444 in the 2005-07-12 change. 10445 10446 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid 10447 warnings from GCC 4. 10448 10449 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack): 10450 (yyglrShiftDefer, yysplitStack): 10451 Remove unused parameters b4_pure_formals. All uses changed. 10452 (yyglrShift): Remove unused parameters b4_user_formals. 10453 All uses changed. 10454 (yyglrReduce): Removed unused parameter yylocp. All uses changed. 10455 10456 2005-07-18 Paul Eggert <eggert (a] cs.ucla.edu> 10457 10458 Destructor cleanups and regularization among the three skeletons. 10459 * NEWS: Document the behavior changes. 10460 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the 10461 stack before failing, as the cleanup code will do it for us now. 10462 * data/lalr1.cc (yyerrlab): Likewise. 10463 * data/glr.c (yyparse): Pop everything off the stack before 10464 freeing it, so that destructors get called properly. 10465 * data/lalr1.cc (yyreturn): Likewise. 10466 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too. 10467 This is more consistent. 10468 * doc/bison.texinfo (Destructor Decl): Mention more reasons 10469 why destructors might be called. 1.875 -> 2.1. 10470 (Destructor Decl, Decl Summary, Table of Symbols): 10471 Some English-language cleanups for %destructor. 10472 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): 10473 Add output line for destructor of start symbol. 10474 * tests/calc.at (AT_CHECK_CALC): Add one to line counts, 10475 because of that same extra output line. 10476 10477 * NEWS: Document minor wording changes in diagnostics of 10478 Bison-generated parsers. 10479 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow. 10480 Remove unused formals. All uses changed. 10481 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous". 10482 (yyparse): Rename yyoverflowlab to yyexhaustedlab. 10483 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted". 10484 Rename yyoverflowab to yyexhaustedlab. 10485 When memory exhaustion occurs during syntax-error reporting, 10486 report it separately rather than in a single diagnostic; this 10487 eases translation. 10488 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow. 10489 (Memory Exhausted): Renamed from Parser Stack Overflow. 10490 Revamp wording slightly to prefer "memory exhaustion". 10491 * tests/actions.at: "parser stack overflow" -> "memory exhausted". 10492 10493 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf. 10494 10495 Add i18n support to the GLR skeleton. Partially fix the C++ 10496 skeleton; a C++ expert needs to finish this. Remove debugging 10497 msgids; there's little point to having them translated, since they 10498 can be understood only by someone who can read the 10499 (English-language) source code. 10500 10501 Generate runtime-po/bison-runtime.pot automatically, so that we 10502 don't have to worry about garbage getting in that file. We'll 10503 make sure after the next official release that old msgids don't 10504 get lost. See 10505 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>. 10506 10507 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove. 10508 Now auto-generated. 10509 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet. 10510 Fix typos in explanations of the runtime file. 10511 * bootstrap: Change gettext keyword from YYI18N to YY_. 10512 Use standard Makefile.in.in in runtime-po, since we'll arrange 10513 for backward-compatible bison-runtime.po files in a different way. 10514 * data/glr.c (YY_): New macro, from yacc.c. 10515 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse): 10516 Translate messages intended for users. 10517 (yyreportSyntaxError): Change "virtual memory" to "memory" to match 10518 the wording in the other skeletons. We don't know that the memory 10519 is virtual. 10520 * data/lalr1.cc (YY_): Renamed from _. All uses changed. 10521 Use same method that yacc.c uses. 10522 Don't translate debugging messages. 10523 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff; 10524 it doesn't work (yet), and requires C++ expertise to fix. 10525 * data/yacc.c (YY_): Renamed from YY18N. All uses changed. 10526 Move defn to a more logical place, to be consistent with other 10527 skeletons. 10528 Don't translate debugging messages. 10529 Don't assume line numbers fit in unsigned int; use unsigned long fmts. 10530 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference 10531 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS. 10532 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc. 10533 10534 Fix yyerror / yylex test glitches noted by twlevo (a] xs4all.nl. 10535 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return 10536 void, not int. 10537 * tests/glr-regression.at (Badly Collapsed GLR States): 10538 Likewise. 10539 (Improper handling of embedded actions and dollar(-N) in GLR parsers): 10540 yylex should return 0 at EOF rather than aborting. 10541 10542 Improve tests for stack overflow in GLR parser. 10543 Problem reported by twlevo (a] xs4all.nl. 10544 * data/glr.c (struct yyGLRStack): Remove yyerrflag member. 10545 All uses removed. 10546 (yyStackOverflow): Just longjmp, but with value 2 so that caller 10547 can handle the problem. 10548 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag. 10549 (yyparse): New local variable yyresult to record the result. 10550 Use result of setjmp to set it, rather than storing itinto 10551 struct. 10552 (yyDone): Remove label. 10553 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels, 10554 to mimic yacc.c. Do not discard lookahead if it's EOF (possible 10555 if YYABORT is used). 10556 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with 10557 yyparse status; put status > 1 into diagnostic. 10558 Check that status==2 works. 10559 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at: 10560 Use exit status 3 for failure to open (which shouldn't happen). 10561 10562 2005-07-17 Paul Eggert <eggert (a] cs.ucla.edu> 10563 10564 * tests/conflicts.at (%nonassoc and eof): Don't exit with status 10565 1 on syntax error; just let yyparse do its thing. 10566 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise. 10567 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise. 10568 (Exploding the Stack Size with Alloca): 10569 (Exploding the Stack Size with Malloc): 10570 Expect exit status 2, not 1, since the parser is supposed to blow 10571 its stack. Problem reported by twlevo (a] xs4all.nl. 10572 10573 * data/glr.c (yyparse): Don't assume that the initial calls 10574 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0. 10575 Print a stack-overflow message and fail instead. 10576 Initialize the line-number information before creating the stack, 10577 so that the stack-overflow message can report line zero safely. 10578 10579 2005-07-14 Paul Eggert <eggert (a] cs.ucla.edu> 10580 10581 Fix problems reported by twlevo (a] xs4all.nl. 10582 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined. 10583 (yyuserMerge): Provide a default case if b4_mergers is empty. 10584 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE. 10585 * tests/glr-regression.at 10586 (Improper handling of embedded actions and dollar(-N) in GLR parsers): 10587 Add casts to pacify C++ compilers. 10588 * tests/glr-regression.at (Improper merging of GLR delayed action 10589 sets): Declare yylex before using it. 10590 * tests/Makefile.am (maintainer-check-g++): Fix a stray 10591 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus 10592 test for valgrind; valgrind is independent of g++. 10593 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check 10594 for compatibility with POSIX 1003.1-2001 (if running coreutils). 10595 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++. 10596 Use a destructor, so that we can expand the stack. Change 10597 YYSTYPE to char * so that we can free it. Cast result of malloc. 10598 10599 2005-07-13 Paul Hilfinger <hilfingr (a] CS.Berkeley.EDU> 10600 10601 * data/glr.c (yyuserAction): Fix uninitialized variable that caused 10602 a valgrind failure.

Geneate it. 10722 Use $(AWK), not gawk, since any conforming Awk will do. 10723 Put comment before action, since older 'make' can't handle comment 10724 in action. 10725 $(BUILT_SOURCES): List all built sources, not just some of them. 10726 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources. 10727 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT. 10728 $($(calc_sources_generated)): Remove unnecessary test for existence 10729 of target.

Allocate a bigger buffer if possible. 10767 Report an error if buffer allocation fails. 10768 (yyStackOverflow): New function. 10769 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether 10770 the initialization was successful. It might fail if storage was 10771 exhausted. 10772 (yyexpandGLRStack): Add more checks for storage allocation failure. 10773 Use yyStackOverflow to report failures. 10774 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction): 10775 (yysplitStack, yyprocessOneStack, yyparse, yypstack): 10776 Don't assume stack number fits in int. 10777 (yysplitStack): Check for storage allocation failure. 10778 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we 10779 can print diagnostics on storage allocation failure. All callers 10780 changed. 10781 (yyresolveValue): Use yybool for boolean. 10782 (yyreportSyntaxError): Check for size-calculation overflow. 10783 This code is taken from yacc.c. 10784 (yyparse): Check for storage allocation errors when allocating 10785 the initial stack. 10786 10787 2005-07-05 Akim Demaille <akim (a] epita.fr> 10788 10789 Extract calc++ from the documentation. 10790 * doc/bison.texinfo (Calc++): Add the extraction marks. 10791 * examples/extexi: New, from the aborted GNU Programming 2E. 10792 Separate the different paragraph of a file with empty lines. 10793 * examples/Makefile: Use it to extract the whole calc++ example. 10794 10795 2005-06-24 Akim Demaille <akim (a] epita.fr> 10796 10797 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define 10798 class typedefs. 10799 10800 2005-06-22 Akim Demaille <akim (a] epita.fr> 10801 10802 * doc/bison.texinfo (C++ Language Interface): First stab. 10803 (C++ Parsers): Remove. 10804 10805 2005-06-22 Akim Demaille <akim (a] epita.fr> 10806 10807 * data/lalr1.cc (yylex_): Honor %lex-param. 10808 10809 2005-06-22 Akim Demaille <akim (a] epita.fr> 10810 10811 Start a set of simple examples. 10812 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc, 10813 * examples/calc++/calc++-driver.hh, 10814 * examples/calc++/calc++-parser.yy, 10815 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc, 10816 * examples/calc++/compile, examples/calc++/test: New. 10817 10818 2005-06-09 Paul Eggert <eggert (a] cs.ucla.edu> 10819 10820 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside 10821 extern "C" {}. This fixes a problem reported by Paul Hilfinger, 10822 which stems from the 2005-05-27 patch. 10823 10824 2005-06-06 Paul Hilfinger <hilfingr (a] tully.CS.Berkeley.EDU> 10825 10826 * data/glr.c: Modify treatment of unused parameters to permit use 10827 of g++ (which doesn't allow __attribute__ ((unused)) for parameters). 10828 10829 2005-05-30 Paul Eggert <eggert (a] cs.ucla.edu> 10830 10831 Fix infringement on user name space reported by Janos Zoltan Szabo. 10832 * data/yacc.c (yyparse): strlen -> yystrlen. 10833 10834 2005-05-30 Akim Demaille <akim (a] epita.fr> 10835 10836 * data/lalr1.cc (_): New. 10837 Translate the various messages. 10838 10839 2005-05-27 Paul Eggert <eggert (a] cs.ucla.edu> 10840 10841 Fix infringement on user name space reported by Bruno Haible. 10842 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it. 10843 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on 10844 the user's name space. 10845 (alloca): Include <stdlib.h> to get it, if it's not built in. 10846 (YYMALLOC, YYFREE): Define only if needed. 10847 (malloc, free): Declare, but only if needed, as this infringes on 10848 the user name space. 10849 10850 2005-05-25 Paul Eggert <eggert (a] cs.ucla.edu> 10851 10852 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible. 10853 * lib/bitset.c (bitset_print): Don't assume size_t can be printed 10854 with %d format. 10855 * lib/ebitset.c (min, max): Undef before defining. 10856 * lib/vbitset.c (min, max): Likewise. 10857 * lib/subpipe.c (create_subpipe): Save local variables in case 10858 vfork clobbers them. 10859 10860 2005-05-24 Bruno Haible <bruno (a] clisp.org> 10861 10862 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the 10863 error message syntax used by gcc-4.0. 10864 10865 2005-05-23 Paul Eggert <eggert (a] cs.ucla.edu> 10866 10867 * README: Mention m4 1.4.3.

Add build-aux, since "bootstrap" now creates it and 10884 its subfiles. 10885 * Makefile.cfg (move_if_change): Remove. 10886 * Makefile.maint: Remove the update stuff; we now use "bootstrap". 10887 (ftp-gnu, www-gnu, move_if_change, local_updates, update): 10888 (po_repo, do-po-update, po-update, wget_files, get-targets): 10889 (config.guess-url_prefix, config.sub-url_prefix): 10890 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix): 10891 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url): 10892 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update): 10893 Remove. 10894 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux; 10895 this is now the recommended name. 10896 * config/.cvsignore: Remove config.guess, config.rpath, config.sub, 10897 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex, 10898 ylwrap.

Problem reported by 11105 Roland McGrath. 11106 11107 2005-03-06 Paul Eggert <eggert (a] cs.ucla.edu> 11108 11109 * src/output.c (escaped_output): Renamed from 11110 escaped_file_name_output, since we now use it for symbol tags as 11111 well. All uses changed. 11112 (symbol_destructors_output, symbol_printers_output): 11113 Escape symbol tags too. 11114 Problem reported by Matyas Forstner in 11115 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>. 11116 11117 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's 11118 not needed. 11119 * src/output.c (user_actions_output, token_definitions_output, 11120 symbol_destructors_output, symbol_printers_output): Likewise. 11121 * src/reader.c (prologue_augment): Likewise. 11122 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise. 11123 11124 * src/vcg.c (output_edge): Don't quote linestyle arg. 11125 Problem reported by twlevo (a] xs4all.nl. 11126 11127 2005-02-28 Paul Eggert <eggert (a] cs.ucla.edu> 11128 11129 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in 11130 example, reported by Derek M Jones.

Beebe. 11201 11202 2005-01-07 Paul Eggert <eggert (a] cs.ucla.edu> 11203 11204 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab 11205 being defined and not used. 11206 * data/lalr1.cc (yyparse): Likewise. 11207 Use "if (false)" rather than "if (0)". 11208 11209 2005-01-05 Paul Eggert <eggert (a] cs.ucla.edu> 11210 11211 * TODO: Mention that we should allow NUL bytes in tokens. 11212 11213 2005-01-02 Paul Eggert <eggert (a] cs.ucla.edu> 11214 11215 * src/scan-skel.l (<<EOF>>): Don't close standard output. 11216 Problem reported by Hans Aberg. 11217 11218 2005-01-01 Paul Eggert <eggert (a] cs.ucla.edu> 11219 11220 * src/getargs.c (version): Happy new year; update overall 11221 program copyright date from 2004 to 2005. 11222 11223 * src/scan-skel.l ("@output ".*\n): Don't close standard output. 11224 Problem reported by Hans Aberg. 11225 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO. 11226 (Output file names.): Add a test for the case when standard output 11227 is closed. 11228 11229 2004-12-26 Paul Eggert <eggert (a] cs.ucla.edu> 11230 11231 * doc/bison.texinfo (@copying): Update FDL version number to 1.2, 11232 to fix an oversight in the Bison 2.0 manual. 11233 11234 2004-12-25 Paul Eggert <eggert (a] cs.ucla.edu> 11235 11236 * NEWS: Version 2.0. Reformat the existing news items since 11237 1.875, so that related items are grouped together. 11238 * configure.ac (AC_INIT): Bump version to 2.0. 11239 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0. 11240 11241 * tests/torture.at (Exploding the Stack Size with Alloca): Set 11242 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined; 11243 otherwise, we're not testing alloca. Unfortunately there's no 11244 simple way to consult HAVE_ALLOCA here. 11245 11246 * data/lalr1.cc (yydestruct_): Pacify unused variable warning 11247 for yymsg, too. 11248 11249 * src/LR0.c (new_itemsets): Use memset rather than zeroing by 11250 hand. This avoids a warning about comparing int to size_t when 11251 GCC warnings are enabled. 11252 11253 2004-12-22 Paul Eggert <eggert (a] cs.ucla.edu> 11254 11255 * NEWS: Bison-generated parsers no longer default to using the 11256 alloca function (when available) to extend the parser stack, due 11257 to widespread problems in unchecked stack-overflow detection. 11258 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's 11259 responsibility to set it to a positive value. This lets the user 11260 specify a value that is not a preprocessor constant. 11261 * data/yacc.c (YYMAXDEPTH): Likewise. 11262 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero. 11263 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs 11264 to be a compile-time constant. However, explain the constraints on it. 11265 Also, explain the constraints on YYINITDEPTH. 11266 (Table of Symbols): Explain that alloca is no longer the default. 11267 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA 11268 to 1. 11269 11270 * doc/bison.texinfo (Location Default Action): Mention that n must 11271 be zero when k is zero.

Problem reported by Baron Schwartz in 11701 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>. 11702 11703 2004-10-11 Akim Demaille <akim (a] epita.fr> 11704 11705 * src/symtab.c (symbol_check_alias_consistency): Also check 11706 type names, destructors, and printers. 11707 Reported by Alexandre Duret-Lutz. 11708 Recode the handling of associativity and precedence in terms 11709 of symbol_precedence_set. 11710 Accept no redeclaration at all, not even equal to the previous 11711 value. 11712 (redeclaration): New. 11713 Use it to factor redeclaration complaints. 11714 (symbol_make_alias): Don't set the type of the alias, let 11715 symbol_check_alias_consistency do it as for other features. 11716 * src/symtab.h (symbol): Add new member prec_location, and 11717 type_location. 11718 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them. 11719 * tests/input.at (Incompatible Aliases): New. 11720 11721 2004-10-09 Paul Eggert <eggert (a] cs.ucla.edu> 11722 11723 .cvsignore fixes to accommodate gnulib changes, 11724 and the practice of naming build directories "_build". 11725 * .cvsignore: Add "_*". Sort. 11726 * lib/.cvsignore: Add getopt_.h, xalloc-die.c. 11727 * m4/.cvsignore: Add "*_gl.m4". 11728 11729 2004-10-06 Akim Demaille <akim (a] epita.fr> 11730 11731 * src/parse-gram.y (add_param): Fix the truncation of trailing 11732 spaces. 11733 11734 2004-10-05 Akim Demaille <akim (a] epita.fr> 11735 11736 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless 11737 whether the reducion was empty or not. This leaves room to 11738 improve the use of YYLLOC_DEFAULT in such a case. 11739 lalr1.cc is still experimental, so changing this is acceptable. 11740 And finally, there are probably not many users who changed the 11741 handling of locations in GLR, so changing is admissible too. 11742 11743 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an 11744 empty reduction, set @$ to an empty location ending the previously 11745 stacked symbol. 11746 Adjust uses to make sure the code is triggered on empty 11747 reductions. 11748 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the 11749 expected output: empty reductions have empty locations. 11750 11751 2004-09-29 Akim Demaille <akim (a] epita.fr> 11752 11753 * data/lalr1.cc: Move towards a more standard C++ coding style 11754 for templates: Class < T > -> Class<T>. 11755 11756 2004-09-29 Akim Demaille <akim (a] epita.fr> 11757 11758 * data/lalr1.cc: Reinstall the former ctor, for sake of 11759 compatibility, but warn it will be removed. 11760 Move towards a more standard C++ coding style (i.e., type *var -> 11761 type* var). 11762 11763 2004-09-27 Paul Eggert <eggert (a] cs.ucla.edu> 11764 11765 * src/parse-gram.y (add_param): Rewrite to avoid strchr, 11766 since it's less likely to work if NULs are involved in the future. 11767 11768 2004-09-27 Akim Demaille <akim (a] epita.fr> 11769 11770 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration. 11771 11772 2004-09-27 Akim Demaille <akim (a] epita.fr> 11773 11774 * data/lalr1.cc (b4_parse_param_decl_1): New. 11775 (b4_parse_param_decl): Use it to have different names between attribute 11776 and argument names. 11777 (b4_cc_constructor_call): Likewise. 11778 11779 2004-09-24 Akim Demaille <akim (a] epita.fr> 11780 11781 * src/parse-gram.y (add_param): Strip the leading and trailing 11782 blanks from a formal argument declaration. 11783 (YY_LOCATION_PRINT): New. 11784 11785 2004-09-24 Akim Demaille <akim (a] epita.fr> 11786 11787 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation 11788 after the location. 11789 11790 2004-09-24 Akim Demaille <akim (a] epita.fr> 11791 11792 * doc/bison.texinfo (Table of Symbols): Sort. 11793 11794 2004-09-21 Akim Demaille <akim (a] epita.fr> 11795 11796 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove 11797 the useless parentheses. 11798 Suggested by Paul Eggert. 11799 11800 2004-09-20 Akim Demaille <akim (a] epita.fr> 11801 11802 Let the initial-action act on the look-ahead, and use it for the 11803 "initial push" (corresponding to an hypothetical beginning-of-file). 11804 And let lalr1.cc honor %initial-action. 11805 11806 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an 11807 example. 11808 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment. 11809 (Parser::Parser): Remove the ctor that used to initialize it. 11810 (Parser::parse): Like in the other skeletons, issue the "starting 11811 parse" message before any action. 11812 Honor %initial-action. 11813 Initialize the stacks with the lookahead. 11814 * data/yacc.c: Let $$ and @$ in %initial-action designate the 11815 look-ahead. 11816 Push them in the stacks. 11817 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations. 11818 11819 2004-09-20 Akim Demaille <akim (a] epita.fr> 11820 11821 * doc/bison.texinfo (Initial Action Decl): New. 11822 11823 2004-09-20 Akim Demaille <akim (a] epita.fr> 11824 11825 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a 11826 clearer criterion to define it. 11827 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL. 11828 When reducing on an empty RHS, use the latest stacked location as 11829 location. 11830 yylloc is not always available. 11831 * data/glr.c: Likewise. 11832 Also, honor initial-actions. 11833 11834 2004-09-20 Akim Demaille <akim (a] epita.fr> 11835 11836 * data/yacc.c (YY_LOCATION_PRINT): New. 11837 Define when we know YYLTYPE's structure, i.e., when the default 11838 YYLLOC_DEFAULT is used. 11839 * data/c.m4 (b4_yysymprint_generate): Use it. 11840 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial 11841 value of the result. 11842 (error_start_): Replace with... 11843 (error_range_): this location array. 11844 This allows to replace code relying on the implementation of 11845 locations by portable code. 11846 * data/yacc.c (yylerrsp): Replace with... 11847 (yyerror_range): this. 11848 Every time a token is popped, update yyerror_range[0], to have an 11849 accurate location for the error token. 11850 * data/glr.c (YY_LOCATION_PRINT): New. 11851 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT: 11852 deference a pointer. 11853 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer 11854 report the location in %printers. 11855 11856 * src/scan-skel.l: Instead of abort, report error messages to ease 11857 understanding skeleton scanning failures. 11858 11859 2004-09-16 Akim Demaille <akim (a] epita.fr> 11860 11861 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as... 11862 (iterator, const_iterator): these, to be more in the C++ spirit. 11863 Also, return reverse iterators so that when displaying the stack 11864 we display its bottom first. 11865 (Parser::stack_print_, Parser::reduce_print_): Match the messages 11866 from yacc.c. 11867 We should probably use vector here though. 11868 11869 2004-09-16 Akim Demaille <akim (a] epita.fr> 11870 11871 Have more complete shift traces. 11872 11873 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT 11874 to report Shifts instead of ad hoc YYDPRINTF invocations, 11875 including for the error token. 11876 * data/lalr1.cc (symprint_): Output the location. 11877 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't 11878 output the location within the %printer. 11879 Activate GLR tests, at least to make sure they compile properly. 11880 They still don't pass though. 11881 * tests/calc.at: Adjust expect verbose output, since now "Entering 11882 state..." is on a different line than the "Shifting" message. 11883 11884 2004-09-08 Akim Demaille <akim (a] epita.fr> 11885 11886 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the 11887 Bison directive from the Bison file to the invocation of this 11888 macro, so that these directives are passed to 11889 AT_BISON_OPTION_PUSHDEFS to get correct help macros. 11890 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth). 11891 Move the AT_SETUP/AT_CLEANUP outside, to report as test title 11892 the extra Bison directives instead of the whole series. 11893 Change the grammar so that there are recoverable errors, and 11894 unrecoverable errors. Now we can have the parser give up before 11895 consuming the whole input. As a result we now can observe that 11896 the lookahead is freed when needed. 11897 Change the parser source to parse argv[1] instead of a hard coded 11898 string. 11899 Simplify yylex, and give a value and location to EOF. 11900 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that 11901 passed directives already coded in the file. 11902 Add some tests to check the location of "error". 11903 For some tests, the C++ parser is correct, and not yacc.c. 11904 For other tests, they provide different, but unsatisfying, values, 11905 so keep the C++ value so that at least one parser is "correct" 11906 according to the test suite. 11907 (Actions after errors): Remove, this is subsumed by the 11908 AT_CHECK_PRINTER_AND_DESTRUCTOR series. 11909 11910 2004-09-06 Akim Demaille <akim (a] epita.fr> 11911 11912 * data/lalr1.cc: Adjust the indentation of the labels. 11913 (Parser::pop): New. 11914 Use it. 11915 11916 2004-09-06 Akim Demaille <akim (a] epita.fr> 11917 11918 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional 11919 argument, an informative message. 11920 Call YY_SYMBOL_PRINT. 11921 Adjust all callers: integrate the associated YY_SYMBOL_PRINT. 11922 * data/lalr1.cc (destruct_): Likewise. 11923 In addition, no longer depend on b4_yysymprint_generate and 11924 b4_yydestruct_generate to generate these functions, do it "by 11925 hand". 11926 11927 2004-09-03 Akim Demaille <akim (a] epita.fr> 11928 11929 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was 11930 invoked, yydestruct the lookahead. 11931 * tests/calc.at (Calculator $1): Update the expected lengths of 11932 traces: there is an added line for the discarded lookahead. 11933 * doc/bison.texinfo (Destructor Decl): Some rewording. 11934 Define "discarded" symbols. 11935 11936 2004-09-02 Akim Demaille <akim (a] epita.fr> 11937 11938 * data/lalr1.cc (translate_, destruct_): No reason to be static. 11939 11940 2004-09-02 Akim Demaille <akim (a] epita.fr> 11941 11942 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used. 11943 (YYDSYMPRINTF): Rename as... 11944 (YY_SYMBOL_PRINT): this. 11945 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous 11946 two. 11947 Use it instead of direct symprint_ calls. 11948 (yybackup): Tweak the "Now at end of input" case to match yacc.c's 11949 one. 11950 11951 2004-09-02 Akim Demaille <akim (a] epita.fr> 11952 11953 * data/lalr1.cc (b4_yysymprint_generate): New. 11954 (symprint_): New member function, defined when YYDEBUG. 11955 Use it consistently instead of token/nterm debugging output by 11956 hand. 11957 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust 11958 %printer calls to use cdebug_ when using lalr1.cc. 11959 11960 2004-08-30 Florian Krohm <florian (a] edamail.fishkill.ibm.com> 11961 11962 * data/glr.c: Guard the declarations of yypstack and yypdumpstack 11963 with #ifdef YYDEBUG. 11964 11965 2004-08-26 Akim Demaille <akim (a] epita.fr> 11966 11967 * doc/bison.texinfo (Implementing Loops): Rename as... 11968 (Implementing Gotos/Loops): this. 11969 11970 2004-08-13 Paul Eggert <eggert (a] cs.ucla.edu> 11971 11972 Adjust to latest gnulib. 11973 * bootstrap (gnulib_modules): Add xalloc-die. 11974 Set LC_ALL=C so that file names sort consistently. 11975 Prefer the gnulib copies of gettext.m4, glibc21.m4, 11976 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4, 11977 uintmax_t.m4, ulonglong.m4. 11978 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4, 11979 po.m4 since we are now using _gl.m4 instead. 11980 11981 2004-08-10 Florian Krohm <florian (a] edamail.fishkill.ibm.com> 11982 11983 * src/scan-action.l: Remove. Scanning of semantic actions is 11984 handled in scan-gram.l. 11985 11986 2004-08-07 Florian Krohm <florian (a] edamail.fishkill.ibm.com> 11987 11988 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup. 11989 11990 * src/location.h (struct): The file member is a uniqstr. 11991 (equal_boundaries): Use UNIQSTR_EQ for comparison. 11992 11993 2004-07-22 Paul Eggert <eggert (a] cs.ucla.edu> 11994 11995 Fix bug with non-%union parsers that have printers or destructors, 11996 which led to a Bison core dump. Reported by Peter Fales in 11997 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>. 11998 11999 * data/c.m4 (b4_symbol_actions): Don't assume %union was used. 12000 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE, 12001 not to our own type. 12002 * src/output.c (symbol_destructors_output, symbol_printers_output): 12003 Don't assume %union. 12004 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR, 12005 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument 12006 UNION-FLAG. All callers changed. 12007 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union. 12008 Use type char, not unsigned int, when declaring an array of char; 12009 this lets us remove a cast. 12010 (Printers and Destructors): Add non-%union test cases. 12011 12012 2004-06-21 Paul Eggert <eggert (a] cs.ucla.edu> 12013 12014 * doc/bison.texinfo: Minor editorial changes, mostly to the new 12015 GLR writeups. E.g., avoid frenchspacing and the future tense, 12016 change "lookahead" to "look-ahead", and change "wrt" to "with 12017 respect to". 12018 12019 2004-06-21 Paul Hilfinger <hilfingr (a] CS.Berkeley.EDU> 12020 12021 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements): 12022 New sections, split off from the GLR Parsers section. Put the new 12023 Simple GLR Parser near the start of the GLR section, for clarity. 12024 Rewrite connective text. 12025 12026 2004-06-21 Frank Heckenbach <frank (a] g-n-u.de> 12027 12028 * doc/bison.texinfo (Simple GLR Parsers): New section. 12029 12030 2004-06-21 Paul Eggert <eggert (a] cs.ucla.edu> 12031 12032 * NEWS, TODO, doc/bison.texinfo: 12033 Use "look-ahead" instead of "lookahead", to be consistent. 12034 * REFERENCES: Fix incorrect reference to DeRemer and Pennello, 12035 while we're fixing "look-ahead". 12036 * src/conflicts.c (shift_set): Renamed from shiftset. 12037 (look_ahead_set): Renamed from lookaheadset. 12038 * src/print.c: Likewise. 12039 * src/getargs.c (report_args): Add "look-ahead" as the new canonical 12040 name for "lookahead". 12041 (report_types, usage): Likewise. 12042 * src/getargs.h (report_look_ahead_tokens): Renamed from 12043 report_lookaheads. 12044 * src/lalr.c (compute_look_ahead_tokens): Renamed from 12045 compute_lookaheads. 12046 (state_look_ahead_tokens_count): Renamed from state_lookaheads_count. 12047 (look_ahead_tokens_print): Renamed from lookaheads_print. 12048 * src/state.c (state_rule_look_ahead_tokens_print): Renamed from 12049 state_rule_lookaheads_print. 12050 * src/state.h: Likewise. 12051 (reductions.look_ahead_tokens): Renamed from lookaheads. 12052 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from 12053 AT_DATA_LOOKAHEADS_GRAMMAR. 12054 12055 2004-06-03 Paul Eggert <eggert (a] cs.ucla.edu> 12056 12057 * README: Update location of patched M4 distribution. 12058 12059 2004-05-30 Albert Chin-A-Young <china (a] thewrittenword.com> 12060 12061 Don't assume the C++ compiler takes the same arguments as the C compiler 12062 (trivial change). 12063 * configure.ac (O0CXXFLAGS): New var. 12064 * tests/atlocal.in (CXXFLAGS): Use it. 12065 12066 2004-05-29 Paul Eggert <eggert (a] cs.ucla.edu> 12067 12068 Fix some "make check" problems with C++ reported by 12069 Albert Chin-A-Young for Tru64 C++ in this thread: 12070 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html 12071 12072 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr. 12073 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): 12074 Output to a .cc file for C++, not to a .c file. 12075 * tests/calc.at (AT_CHECK_CALC): Likewise. 12076 * tests/regression.at (AT_CHECK_DANCER): Likewise. 12077 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c. 12078 12079 2004-05-28 Albert Chin-A-Young <china (a] thewrittenword.com> 12080 12081 * tests/calc.at, tests/actions.at: Workaround for SGI 12082 C++ compiler. (trivial change) 12083 12084 2004-05-27 Paul Eggert <eggert (a] cs.ucla.edu> 12085 12086 Spent a few hours checking out which prerequisite versions the 12087 current sources actually require. I went all the way back to 12088 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated 12089 a seemingly endless set of combinations of versions more recent 12090 than that. The bottom line is that the current sources require 12091 fairly recent versions of the build tools, and it'll be some work 12092 to change this. 12093 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59. 12094 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8. 12095 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12. 12096 Add comments explaining why those particular versions are 12097 currently needed. 12098 12099 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug 12100 in SGI MIPSpro 7.4.1m.

Suggested by Bruno Haible. 12110 * bootstrap: Remove gettext version checking. 12111 12112 * doc/bison.texinfo (Decl Summary): Also mention that %union 12113 can depend on prerequisite types. Problem reported by Tim 12114 Van Holder. 12115 12116 2004-05-25 Paul Eggert <eggert (a] cs.ucla.edu> 12117 12118 * README: Mention GNU m4 1.4 bugs and Akim's patched version. 12119 * README-alpha: Don't tell people not to package this. 12120 12121 * bootstrap: Don't assume $(...) works; use `...` instead. 12122 Problem reported by Paul Hilfinger. Also, diagnose non-GNU 12123 gettext better. 12124 12125 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's 12126 put into the -d output file, and mention what to do if YYSTYPE is 12127 defined as a macro. 12128 12129 2004-05-24 Paul Eggert <eggert (a] cs.ucla.edu> 12130 12131 Undo change made earlier today: it caused autopoint to not bring 12132 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for 12133 autopoint's. 12134 12135 * bootstrap: Check that gettext version matches what's in 12136 configure.ac. Warn users to ignore robots.txt ERROR 404. 12137 * bootstrap: Undo today's earlier change (logged below). 12138 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise. 12139 12140 The gettext version checking is causing more trouble than it's 12141 curing; remove it. Problem reported by Paul Hilfinger. 12142 12143 * bootstrap: Issue a warning that one can expect a message 12144 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'. 12145 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove. 12146 12147 2004-05-23 Paul Eggert <eggert (a] cs.ucla.edu> 12148 12149 Ensure that the C++ compiler used for testing actually works on a 12150 simple test program; if not, skip the C++-related tests.

Johnson 12164 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>. 12165 12166 * configure.ac (AC_INIT): Update to 1.875e. 12167 12168 2004-05-21 Paul Eggert <eggert (a] cs.ucla.edu> 12169 12170 * NEWS: Version 1.875d. 12171 * configure.ac (AC_INIT): Likewise. 12172 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d. 12173 12174 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow, 12175 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current 12176 lalr1.cc runs afoul of the first, and the last two are no longer 12177 supported by GCC 3.4.0. 12178 * README: Mention GNU m4 1.4 or later; mention m4 patches. 12179 * HACKING: Use ./bootstrap, not "make update" to import foreign files. 12180 12181 2004-05-06 Paul Eggert <eggert (a] cs.ucla.edu> 12182 12183 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not 12184 unsigned int, for compatibility with latest gnulib hash module. 12185 * src/state.c (state_hash, state_hasher): Likewise. 12186 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise. 12187 * src/uniqstr.c (hash_uniqstr): Likewise. 12188 12189 2004-05-03 Paul Eggert <eggert (a] cs.ucla.edu> 12190 12191 * NEWS: Unescaped newlines are no longer allowed in char & strings. 12192 12193 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER, 12194 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in 12195 character and string literals. 12196 (unexpected_end): New function. 12197 (unexpected_eof): Use it. 12198 (unexpected_newline): New function. 12199 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate 12200 actions. 12201 12202 * NEWS: Document %expect-rr. 12203 12204 * bootstrap (--gnulib-srcdir=*, --cvs-user=*): 12205 Fix typo by replacing $1 with $option. 12206 Remove more 'intl'-related files. 12207 Don't DEFUN AM_INTL_SUBDIR twice. 12208 12209 * lib/.cvsignore: Add strndup.h.

Upgrade to latest versions of gnulib 12226 and Automake. 12227 12228 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4. 12229 * bootstrap: Bootstrap from gnulib and po repositories. 12230 Much of this code was stolen from GNU diff and GNU tar's bootstrap. 12231 * README-cvs: Document these changes. Remove version numbers from 12232 mentions of build tools, since they change so often. Mention Flex. 12233 12234 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg. 12235 (gl_USE_SYSTEM_EXTENSIONS): Add. 12236 (AC_GNU_SOURCE, AC_AIX, AC_MINIX): 12237 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS 12238 does this for us. 12239 (AC_ISC_POSIX): Remove; we no longer support this 12240 ancient OS, as it gets in the way of latest Autoconf & gnulib. 12241 (AC_HEADER_STDC): Remove: we now assume C89 or better. 12242 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS. 12243 Do not check for C89 headers, except for locale.h which is used 12244 by the Yacc library and must port to K&R hosts. 12245 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS. 12246 Do not check for C89 functions, except for setlocale which is 12247 used by the Yacc library. 12248 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed. 12249 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR, 12250 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL, 12251 gl_GETOPT, gl_HASH, gl_MBSWIDTH, gl_OBSTACK, gl_QUOTE, 12252 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC, 12253 AM_GNU_GETTEXT): Remove; now done by: 12254 (GNULIB_AUTOCONF_SNIPPET): Add.

C99 requires this. 12827 12828 2003-06-09 Paul Hilfinger <Hilfinger (a] CS.Berkeley.EDU> 12829 12830 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0 12831 first. 12832 (yyrecoverSyntaxError): Correct the logic for setting and testing 12833 yyerrState. 12834 Correct comment on handling EOF. 12835 Allow states with only a default reduction, rather than failing 12836 (I can't quite reconstruct why these were not allowed before). 12837 12838 Fixes to avoid problem that $-N rules in GLR parsers can cause 12839 buffer overruns, corrupting state. 12840 12841 * src/output.c (prepare_rules): Output max_left_semantic_context 12842 definition. 12843 * src/reader.h (max_left_semantic_context): New variable declaration. 12844 * src/scan-gram.l (max_left_semantic_context): Define. 12845 (handle_action_dollar): Update max_left_semantic_context. 12846 * data/glr.c (YYMAXLEFT): New definition. 12847 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT. 12848 (yyresolveAction): Ditto. 12849 12850 Fixes to problems with location handling in GLR parsers reported by 12851 Frank Heckenbach (2003/06/05). 12852 12853 * data/glr.c (YYLTYPE): Make trivial if locations not used. 12854 (YYRHSLOC): Add parentheses, and define only if locations used. 12855 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if 12856 locations not used. 12857 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp. 12858 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp. 12859 12860 * tests/cxx-type.at: Exercise location information;

Change 12866 output to prefix notation and update test data and expected results. 12867 (yylex): Track locations. 12868 (stmtMerge): Return value rather than printing, and include arguments 12869 in value. 12870 12871 2003-06-03 Paul Eggert <eggert (a] twinsun.com> 12872 12873 Avoid warnings generated by GCC 2.95.4 when Bison is 12874 configured with --enable-gcc-warnings. 12875 * data/lalr1.cc (yy::]b4_parser_class_name[::parse, 12876 yy::]b4_parser_class_name[::translate_, 12877 yy::Stack::operator[] (unsigned), 12878 yy::Stack::operator[] (unsigned) const, 12879 yy::Slice::operator[] (unsigned), 12880 yy::Slice::operator[] (unsigned) const): 12881 Rename local vars to avoid warnings. 12882 * tests/glr-regression.at (Improper handling of embedded actions 12883 and $-N in GLR parsers): Remove unused local variable from yylex. 12884 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take 12885 (void) as arg when not pure, since we now assume C89 when building 12886 Bison. Pacify GCC by using parameter. 12887 12888 2003-06-02 Paul Eggert <eggert (a] twinsun.com> 12889 12890 * data/lalr1.cc (yy::Position::lines, yy::Position::columns, 12891 yy::Location::lines, yy::Location::columns): Rename arguments 12892 to avoid shadowing; this removes a warning generated by GCC 3.3. 12893 12894 2003-06-01 Paul Eggert <eggert (a] twinsun.com> 12895 12896 Don't pass C-only warning optins (e.g., -Wmissing-declarations) 12897 to g++, as GCC 3.3 complains if you do it. 12898 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to 12899 everything that WARNING_CFLAGS has, except omit warnings 12900 not suitable for C++. 12901 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]). 12902 * tests/atlocal.in (CXXFLAGS): New var. 12903 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS. 12904 12905 Fix a GLR parser bug I reported in February; see 12906 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>. 12907 The problem was that GLR parsers did not conform to the C standard, 12908 because actions like { $1 = $2 + $3; } expanded to expressions 12909 that invoked YYFILL in separate subexpressions, and YYFILL assigned 12910 to a local variable. The C standard says that expressions 12911 like (var = f ()) + (var = f ()) have undefined behavior. 12912 Another problem was that GCC sometimes issues warnings that 12913 yyfill and its parameters are unused. 12914 12915 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark 12916 as possibly unused. 12917 (yyfill): New function. 12918 (YYFILL): Use it. 12919 (yyuserAction): Change type of yynormal to bool, so that it matches 12920 the new yyfill signature. Mark it as possibly unused. 12921 12922 12923 Follow up on a bug I reported in February, where a Bison-generated 12924 parser can loop. Provide a test case and a fix for yacc.c. I 12925 don't have a fix for lalr1.cc or for glr.c, unfortunately. 12926 The original bug report is in: 12927 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html> 12928 12929 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the 12930 macro's size was becoming unwieldy. 12931 (yyerrlab): Do not discard an empty lookahead symbol, as this 12932 might destroy garbage. 12933 (yyerrorlab): New label, with the old contents of YYERROR, 12934 plus the following change: pop the stack of rhs corresponding 12935 to the production that invoked YYERROR. That is how Yacc 12936 behaves, and POSIX requires this behavior. 12937 (yyerrlab1): Use YYPOPSTACK instead of its definiens. 12938 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available. 12939 Define 'alarm' to do nothing if unistd.h is not available. 12940 Add a new rule "exp: '-' error;" to test the above change to 12941 data/yacc.c. Use 'alarm' to abort any test taking longer than 12942 10 seconds, as it's probably looping. 12943 (AT_CHECK_CALC): Test recovery from error in new grammar rule. 12944 Also, the new yacc.c generates two fewer diagnostics for an 12945 existing test. 12946 12947 2003-05-24 Paul Eggert <eggert (a] twinsun.com> 12948 12949 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate 12950 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined. 12951 This fixes a problem reported by John Bowman when the Compaq/HP 12952 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM 12953 -ansi -Wall -gall). 12954 * data/yacc.c (union yyalloc): Likewise. 12955 (YYCOPY): Do not evaluate __GNUC__ unless it is defined. 12956 12957 Switch from 'int' to 'bool' where that makes sense. 12958 12959 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p, 12960 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp, 12961 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or, 12962 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp): 12963 Return or accept bool, not int.

This change is from Paul Hilfinger, and it fixes 13143 regression reported by Werner Lemberg in 13144 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>. 13145 13146 (resolve_sr_conflict): Don't invoke state_errs_set 13147 unless one or more tokens have been explicitly made errors. 13148 Otherwise, the above change causes Bison to abort. 13149 13150 * tests/existing.at (GNU pic Grammar): New test case, taken from 13151 Lemberg's email. 13152 13153 2003-03-31 Akim Demaille <akim (a] epita.fr> 13154 13155 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file. 13156 13157 2003-03-31 Akim Demaille <akim (a] epita.fr> 13158 13159 * src/output.c (prepare_symbols): Avoid trailing spaces in the 13160 output. 13161 13162 2003-03-31 Akim Demaille <akim (a] epita.fr> 13163 13164 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/. 13165 From Paul Hilfinger. 13166 13167 2003-03-29 Akim Demaille <akim (a] epita.fr> 13168 13169 * m4/error.m4: Do not put under dynamic conditions some code which 13170 expansion is under static control. 13171 13172 2003-03-29 Akim Demaille <akim (a] epita.fr> 13173 13174 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New. 13175 13176 2003-03-29 Akim Demaille <akim (a] epita.fr> 13177 13178 * doc/bison.texinfo (Strings are Destroyed): New. 13179 13180 2003-03-13 Paul Eggert <eggert (a] twinsun.com> 13181 13182 * .cvsignore: Add configure.lineno. 13183 * src/.cvsignore: Add yacc. 13184 * tests/.cvsignore: Add testsuite.log. 13185 * doc/fdl.texi: Sync with latest FSF version. 13186 13187 2003-03-12 Paul Eggert <eggert (a] twinsun.com> 13188 13189 * scan-gram.l (YY_USER_INIT): Initialize code_start, too. 13190 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner 13191 cursor, instead of leaving it undefined. This fixes a bug 13192 reported by Tim Van Holder in 13193 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>. 13194 * tests/input.at (Torturing the Scanner): Test the scanner on 13195 an empty input file, which was Tim Van Holder's test case. 13196 13197 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether 13198 <sys/resource.h> can be included, include sys/time.h and 13199 sys/times.h first, if available. This works around the SunOS 13200 4.1.4 porting bug reported by Bruce Becker in 13201 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>. 13202 13203 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't 13204 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with 13205 AC_HEADER_SYS_WAIT. 13206 13207 Merge changes from gnulib. This was prompted because the CVS 13208 snapshot didn't build on Solaris 7 due to strnlen problems. 13209 13210 These changes need to be merged back into gnulib: 13211 * lib/hash.c: Include <stdbool.h> unconditionally. 13212 * m4/onceonly.m4 (m4_quote): New macro. 13213 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE): 13214 Quote AC_FOREACH variable-expansions properly. 13215 The 2003-01-03 obstack.h change also needs merging. 13216 {end of changes requiring merging} 13217 13218 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4, 13219 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4, 13220 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4, 13221 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4, 13222 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4: 13223 New files, imported from gnulib. 13224 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned 13225 above. 13226 13227 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4, 13228 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current 13229 gnulib sources. 13230 13231 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC): 13232 Add. 13233 (gl_ERROR): New, replacing jm_PREREQ_ERROR. 13234 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA. 13235 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy). 13236 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN. 13237 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH. 13238 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK. 13239 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG. 13240 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New. 13241 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC. 13242 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC. 13243 (jm_PREREQ_ARGMATCH): Remove. 13244 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul. 13245 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h. 13246 13247 * src/system.h: Include <stdbool.h> unconditionally. 13248 13249 * lib/bbitset.h: Include <limits.h> unconditionally.

An alternative would be making it static, but 13309 then it starts with the second %%'s beginning, instead of its end. 13310 13311 2003-02-28 Paul Eggert <eggert (a] twinsun.com> 13312 13313 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work 13314 around a UnixWare 7.1.1 porting bug reported by John Hughes in 13315 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>. 13316 13317 2003-02-26 Paul Eggert <eggert (a] twinsun.com> 13318 13319 * README: Mention compiler bug in Sun Forte Developer 6 update 2. 13320 Remove Sequent/Pyramid discussion (nobody uses them any more). 13321 Merge VMS and MS-DOS discussion; these ports may well be dead 13322 but let's keep mentioning them for now.

Eken). 13558 Update copyright notice. 13559 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at. 13560 * tests/Makefile.am: Ditto. 13561 13562 2003-01-28 Paul Eggert <eggert (a] twinsun.com> 13563 13564 * data/lalr1.cc: Do not use @output_header_name@ unless 13565 b4_defines_flag is set. This fixes two bugs reported by 13566 Tim Van Holder in 13567 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html> 13568 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>. 13569 13570 2003-01-21 Paul Eggert <eggert (a] twinsun.com> 13571 13572 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that 13573 we don't need to worry about yyerrlab1 being reported as an 13574 "unused label" by non-GCC C compilers. The downside is that if 13575 locations are used then a couple of statements are duplicated each 13576 time YYERROR is invoked, but the upside is that the warnings 13577 should vanish. 13578 (yyerrlab1): Move code to YERROR. 13579 (yyerrlab2): Remove. Change uses back to yyerrlab1. 13580 This reverts some of the 2002-12-27 change. 13581 13582 2003-01-17 Paul Eggert <eggert (a] twinsun.com> 13583 13584 * src/output.c (symbol_printers_output): Fix typo that led 13585 to core dump. Problem reported by Antonio Rus in 13586 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>. 13587 13588 2003-01-13 Akim Demaille <akim (a] epita.fr>, 13589 Quoc Peyrot <chojin (a] lrde.epita.fr>, 13590 Robert Anisko <anisko_r (a] lrde.epita.fr> 13591 13592 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop 13593 when the stacks contain one element, as the loop would otherwise 13594 free the last state, and then use the top state (the one we just 13595 popped). This means that the initial elements will not be freed 13596 explicitly, as is the case in yacc.c; it is not a problem, as 13597 these elements have fake values. 13598 13599 2003-01-11 Paul Eggert <eggert (a] twinsun.com> 13600 13601 * NEWS: %expect-violations are now just warnings, reverting 13602 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2 13603 bootstrapping problem reported by Matthias Klose; see 13604 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>. 13605 * src/conflicts.c (conflicts_print): Likewise. 13606 * tests/conflicts.at (%expect not enough, %expect too much, 13607 %expect with reduce conflicts): Likewise. 13608 * doc/bison.texinfo (Expect Decl): Document this. Also mention 13609 that the warning is enabled if the number of conflicts changes 13610 (not necessarily increases). 13611 13612 * src/getargs.c (version): Update copyright year. 13613 13614 2003-01-09 Akim Demaille <akim (a] epita.fr> 13615 13616 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@. 13617 13618 2003-01-08 Paul Eggert <eggert (a] twinsun.com> 13619 13620 * Makefile.maint (WGETFLAGS): 13621 New macro, containing "-C off" to disable proxy caches. 13622 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS). 13623 (rel-check): Use $(WGET) instead of wget. 13624 13625 2003-01-06 Paul Eggert <eggert (a] twinsun.com> 13626 13627 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to 13628 the GLR paper of Scott, Johnstone and Hussain. 13629 13630 2003-01-04 Paul Eggert <eggert (a] twinsun.com> 13631 13632 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc. 13633 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST. 13634 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@. 13635 (EXTRA_LIBRARIES): New var, for liby.a. 13636 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@. 13637 (EXTRA_SCRIPTS): New var, for yacc. 13638 13639 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined, 13640 since GNU C++ (as of 3.2.1) does not allow attributes on labels. 13641 Problem reported by Nelson H. F. Beebe. 13642 13643 2003-01-03 Paul Eggert <eggert (a] twinsun.com> 13644 13645 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to 13646 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5 13647 when compiling Bison 1.875's `bitset bset = obstack_alloc 13648 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe. 13649 13650 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition. 13651 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not 13652 grow to a huge size with typical invocation. 13653 13654 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined): 13655 Use the pattern recommended by Autoconf 2.57, except also protect 13656 against double-definition. 13657 * src/system.h: Likewise. 13658 Portability issues reported by Nelson H. F. Beebe. 13659 13660 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C. 13661 All uses changed. Provide a definition in both C and C++. 13662 (yytrue, yyfalse): Define even if defined (__cplusplus). 13663 13664 * lib/bitset_stats.c (bitset_stats_list): Remove unused var. 13665 Reported by Nelson H. F. Beebe. 13666 13667 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno. 13668 13669 2003-01-02 Paul Eggert <eggert (a] twinsun.com> 13670 13671 * data/yacc.c (yyerrlab1): Append `;' after attribute, to 13672 pacify the buggy "smart preprocessor" in MacOS 10.2.3. 13673 Bug reported by Nelson H. F. Beebe. 13674 13675 2003-01-01 Paul Eggert <eggert (a] twinsun.com> 13676 13677 * Version 1.875. 13678 13679 2002-12-30 Paul Eggert <eggert (a] twinsun.com> 13680 13681 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","): 13682 Moved here from... 13683 (<INITIAL>","): Here. This causes stray "," to be treated 13684 more uniformly. 13685 13686 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the 13687 last brace in braced code when not in Yacc mode, for compatibility 13688 with Bison 1.35. This resurrects the 2001-12-15 patch to 13689 src/reader.c. 13690 13691 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias 13692 yystype. This follows up the 2002-12-24 YYSTYPE bug fix. 13693 13694 2002-12-28 Paul Eggert <eggert (a] twinsun.com> 13695 13696 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be 13697 that of SYM's type. This fixes Debian bug 168069, reported by 13698 Thomas Olsson. 13699 13700 2002-12-28 Paul Eggert <eggert (a] twinsun.com> 13701 13702 Version 1.75f. 13703 13704 Switch back to the Yacc style of conflict reports, undoing some 13705 of the 2002-07-30 change. 13706 * doc/bison.texinfo (Understanding): Use Yacc style for 13707 conflict reports. Also, use new way of locating rules. 13708 * src/conflicts.c (conflict_report): 13709 Renamed from conflict_report_yacc, removing the old 13710 'conflict_report'. Translate the entire conflict report at once, 13711 so that we don't assume that "," has the same interpretation in 13712 all languages. 13713 (conflicts_output): Use Yacc-style conflict report for each state, 13714 instead of our more-complicated style. 13715 (conflicts_print): Use Yacc-style conflict report, except print 13716 the input file name when not emulating Yacc. 13717 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted 13718 Conflicted Reduction, %expect not enough, %expect too much, 13719 %expect with reduce conflicts): Switch to Yacc-style conflict reports. 13720 * tests/existing.at (GNU Cim Grammar): Likewise. 13721 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise. 13722 13723 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at, 13724 fatal): Don't invoke fflush; it's not needed and it might even be 13725 harmful for stdout, as stdout might not be open. 13726 * src/reduce.c (reduce_print): Likewise. 13727 13728 2002-12-27 Paul Eggert <eggert (a] twinsun.com> 13729 13730 Fix a bug where error locations were not being recorded correctly. 13731 This problem was originally reported by Paul Hilfinger in 13732 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>. 13733 13734 * data/yacc.c (yyparse): New local var yylerrsp, to record the 13735 top of the location stack's error locations. 13736 (yyerrlab): Set it. When discarding a token, push its location 13737 onto yylerrsp so that we don't lose track of the error's end. 13738 (yyerrlab1): Now is only the target of YYERROR, so that we can 13739 properly record the location of the action that failed. For GCC 13740 2.93 and later, insert an __attribute__ ((__unused__)) to avoid 13741 GCC warning about yyerrlab1 being unused if YYERROR is unused. 13742 (yyerrlab2): New label, which yyerrlab now falls through to. 13743 Compute the error's location by applying YYLLOC_DEFAULT to 13744 the locations of all the symbols that went into the error. 13745 * doc/bison.texinfo (Location Default Action): Mention that 13746 YYLLOC_DEFAULT is also invoked for syntax errors. 13747 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): 13748 Error locations include the locations of all the tokens that were 13749 discarded, not just the last token. 13750 13751 2002-12-26 Paul Eggert <eggert (a] twinsun.com> 13752 13753 * src/files.c: Include quote.h. 13754 (compute_output_file_names): Warn if we detect conflicting 13755 outputs to the same file. This should catch the misunderstanding 13756 exemplified by Debian Bug 165349, reported by Bruce Stephens.. 13757 13758 * src/conflicts.c (conflicts_print): If the user specifies 13759 "%expect N", report an error if there are any reduce/reduce 13760 conflicts. This is what the manual says should happen. 13761 This fixes Debian bug 130890, reported by Anthony DeRobertis. 13762 * tests/conflicts.at (%expect with reduce conflicts): New test. 13763 13764 Don't use m4_include on relative file names, as it doesn't work as 13765 desired if there happens to be a file with that name under ".". 13766 13767 * m4sugar/version.m4: Remove; it was included but it wasn't used. 13768 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4. 13769 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4. 13770 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4. 13771 * src/output.c (output_skeleton): Use full path names when 13772 specifying a file to include; don't rely on include path, as 13773 it's unreliable when the working file contains a file with 13774 that name. 13775 13776 2002-12-25 Paul Eggert <eggert (a] twinsun.com> 13777 13778 Remove obsolete references to bison.simple and bison.hairy. 13779 Problem mentioned by Aubin Mahe in 13780 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>. 13781 * data/glr.c: Comment fix. 13782 * doc/bison.1: Remove references. Also, mention "yacc". 13783 13784 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL 13785 with -g option. 13786 13787 * src/parse-gram.y (declaration): Use enum "report_states" rather 13788 than its numeric value 1. 13789 13790 * src/scan-skel.l ("@output ".*\n): Close any old yyout before 13791 opening a new one. This fixes Debian bug 165349, reported by 13792 Bruce Stephens. 13793 13794 2002-12-24 Paul Eggert <eggert (a] twinsun.com> 13795 13796 Version 1.75e. 13797 13798 * Makefile.maint (cvs-update): Don't assume that the shell 13799 supports $(...), as Solaris sh doesn't. 13800 13801 * src/parse-gram.y (lloc_default): Remove test for empty 13802 nonterminals at the end, since it didn't change the result. 13803 13804 2002-12-24 Paul Eggert <eggert (a] twinsun.com> 13805 13806 If the user does not define YYSTYPE as a macro, Bison now declares it 13807 using typedef instead of defining it as a macro. POSIX requires this. 13808 For consistency, YYLTYPE is also declared instead of defined. 13809 13810 %union directives can now have a tag before the `{', e.g., the 13811 directive `%union foo {...}' now generates the C code 13812 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility. 13813 The default union tag is `YYSTYPE', for compatibility with Solaris 9 13814 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE' 13815 instead of `yyltype'. 13816 13817 `yystype' and `yyltype' are now obsolescent macros instead of being 13818 typedefs or tags; they are no longer documented and will be 13819 withdrawn in a future release. 13820 13821 * data/glr.c (b4_location_type): Remove. 13822 (YYSTYPE): Renamed from yystype. 13823 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef. 13824 (struct YYLTYPE): Renamed from struct yyltype. 13825 (YYLTYPE): Renamed from yyltype. 13826 (yyltype, yystype): New (and obsolescent) macros, 13827 for backward compatibility. 13828 * data/yacc.c: Likewise. 13829 13830 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user 13831 does not specify a union tag. This is for compatibility with 13832 Solaris 9 yacc. 13833 13834 * src/parse-gram.y (add_param): 2nd arg is now char * not char 13835 const *, since it is now modified by stripping surrounding { }. 13836 (current_braced_code): Remove. 13837 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION, 13838 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include 13839 trailing " {...}". Now of type <chars>. 13840 (grammar_declaration): Adjust to bundled tokens. 13841 (code_content): Remove; stripping is now done by add_param. 13842 (print_token_value): Print contents of bundled tokens. 13843 (token_name): New function. 13844 13845 * src/reader.h (braced_code, current_braced_code): Remove. 13846 (token_name): New decl. 13847 13848 * src/scan-gram.l (handle_dollar, handle_at): Now takes int 13849 token_type, not braced_code code_kind.

Begin state SC_AFTER_IDENTIFIER 14254 instead of returning ID immediately, since we need to search for 14255 a subsequent colon. 14256 (<INITIAL>"'", "\""): Save token_start. 14257 (<INITIAL>"%{", "{", "%%"): Save code_start. 14258 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon. 14259 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>): 14260 BEGIN context_state at end, not INITIAL. 14261 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'", 14262 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>): 14263 Return correct token start. 14264 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when 14265 the start of a character, string or multiline comment is found. 14266 * tests/conflicts.at (S/R in initial, Defaulted Conflicted 14267 Reduction): Adjust reported locations to match the more-precise 14268 results now expected. 14269 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise. 14270 * tests/reduce.at (Useless Rules, Reduced Automaton, 14271 Underivable Rules): Likewise. 14272 * tests/regression.at (Invalid inputs): No longer `expecting ";" 14273 or "|"' now that so many other tokens are allowed by the new grammar. 14274 14275 * src/complain.h (current_file): Remove duplicate decl; 14276 current_file is now owned by files.h. 14277 * src/complain.c, src/scan-gram.l: Include files.h. 14278 14279 2002-12-06 Paul Eggert <eggert (a] twinsun.com> 14280 14281 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule] 14282 promotes to int; it might be unsigned int. 14283 * data/yacc.c (yy_reduce_print): Likewise. 14284 14285 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should 14286 be #defined in the prologue, not in the Bison declarations. 14287 This fixes Debian Bug 102878, reported by Shaul Karl. 14288 14289 2002-12-02 Paul Eggert <eggert (a] twinsun.com> 14290 14291 * configure.ac (AC_REPLACE_FUNCS): Add strtoul. 14292 * lib/strtoul.c: New file, from gnulib. 14293 This fixes a porting bug reported by Peter Klein in 14294 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>. 14295 14296 2002-11-30 Paul Eggert <eggert (a] twinsun.com> 14297 14298 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue, 14299 and put only a forward declaration in the prologue. This is for 14300 consistency with the other scanner helper functions. 14301 14302 Type clashes now generate warnings, not errors, since it 14303 appears that POSIX may allow some grammars with type clashes. 14304 * src/reader.c (grammar_current_rule_check): Warn about 14305 type clashes instead of complaining. 14306 * tests/input.at (Type Clashes): Expect warnings, not complaints. 14307 14308 Add Yacc library, since POSIX requires it. 14309 * doc/bison.texinfo (Yacc Library): New node.

Add static decl. 14316 (print_token_value): Omit parameter names from forward decl, 14317 for consistency. 14318 14319 2002-11-29 Paul Eggert <eggert (a] twinsun.com> 14320 14321 * doc/bison.texinfo: Emphasize that yylex and yyerror must 14322 be declared before being used. E.g., one should typically 14323 declare them in the prologue. Use GNU coding style in examples. 14324 Put "const" consistently after the type it modifies. Mention 14325 that C99 supports "inline". Mention that yyerror traditionally 14326 returns "int". 14327 14328 %parse-param and %lex-param now take just one argument, the 14329 declaration; the argument name is deduced from the declaration. 14330 14331 * doc/bison.texinfo (Parser Function, Pure Calling, Error 14332 Reporting, Table of Symbols): Document this. 14333 * src/parse-gram.y (add_param): New function. 14334 (COMMA): Remove. 14335 (declaration): Implement new rule for %parse-param and %lex-param. 14336 * src/scan-gram.l: "," now elicits a warning, rather than being 14337 a token; this is more compatible with byacc. 14338 * tests/calc.at (Simple LALR Calculator): Adopt new convention. 14339 14340 2002-11-27 Paul Eggert <eggert (a] twinsun.com> 14341 14342 Rename identifiers to avoid real and potential collisions. 14343 14344 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput, 14345 to avoid collision with lex macro described by Bruce Lilly in 14346 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>. 14347 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise. 14348 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value. 14349 * src/parse-gram.y (print_token_value): Renamed from yyprint. 14350 All uses changed. 14351 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed. 14352 The name "yycontrol" violates the name space rules, and this stuff 14353 wasn't being used anyway. 14354 (input): Remove action; this stuff wasn't being used. 14355 (gram_error): Rename local variable yylloc -> loc. 14356 * src/reader.h (struct gram_control_s, gram_control_t): Remove. 14357 (YY_DECL): Don't use "yy" at start of local variables. 14358 All uses changed, e.g., yylloc -> loc. 14359 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed. 14360 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed. 14361 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed. 14362 (STRING_FREE): Renamed from YY_OBS_FREE.

This change is required for POSIX conformance. 14381 14382 * lib/error.c: Sync with gnulib. 14383 14384 2002-11-22 Paul Eggert <eggert (a] twinsun.com> 14385 14386 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib. 14387 * lib/mbswidth.c, lib/mbswidth.h: Likewise. 14388 * lib/xmalloc.c: Likewise. 14389 14390 2002-11-20 Paul Eggert <eggert (a] twinsun.com> 14391 14392 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib. 14393 14394 2002-11-20 Paul Eggert <eggert (a] twinsun.com> 14395 14396 Avoid use of <assert.h>, as the GNU Coding Standards hint that one 14397 should use `if (! x) abort ();' rather than `assert (x);', and 14398 anyway it's one less thing to worry about configuring. 14399 14400 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>. 14401 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise, 14402 and replace all instances of assert with abort. 14403 * tests/calc.at (_AT_DATA_CALC_Y): Likewise. 14404 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise. 14405 14406 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates, 14407 yyresolveAction, yyprocessOneStack): Use abort rather than assert. 14408 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next, 14409 hash_find_entry, hash_rehash, hash_insert): Likewise. 14410 * src/conflicts.c (resolve_sr_conflict): Likewise. 14411 * src/lalr.c (set_goto_map, map_goto): Likewise. 14412 * src/nullable.c (nullable_compute): Likewise. 14413 * src/output.c (prepare_rules, token_definitions_output): Likewise. 14414 * src/reader.c (packgram, reader): Likewise. 14415 * src/state.c (state_new, state_free, state_transitions_set, 14416 state_reduction_find): Likewise. 14417 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias, 14418 symbol_pack): Likewise. 14419 * src/tables.c (conflict_row, pack_vector): Likewise. 14420 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str, 14421 get_layoutalgorithm_str, get_decision_str, get_orientation_str, 14422 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str, 14423 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise. 14424 14425 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef. 14426 (ARGMATCH_CONSTRAINT): New macro. 14427 (ARGMATCH_ASSERT): Use it. 14428 14429 * src/system.h (verify): New macro. 14430 * src/getargs.c (trace_argmatch, report_argmatch): Use verify 14431 rather than assert. 14432 * src/tables.c (tables_generate): Likewise. 14433 14434 * src/struniq.c (struniq_assert): Now returns void, and aborts 14435 if the assertion is false. 14436 (struniq_assert_p): Remove. 14437 * src/struniq.h: Likewise. 14438 14439 2002-11-18 Paul Eggert <eggert (a] twinsun.com> 14440 14441 * data/glr.c (yygetLRActions): Replace `yyindex' with 14442 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch. 14443 This fixes the regression with Sun ONE Studio 7 cc that I reported in 14444 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>. 14445 14446 2002-11-18 Akim Demaille <akim (a] epita.fr> 14447 14448 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a 14449 space. 14450 From Tim Van Holder. 14451 14452 2002-11-17 Paul Eggert <eggert (a] twinsun.com> 14453 14454 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError" 14455 to "SyntaxError" for consistency with my 2002-11-15 change. 14456 14457 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do 14458 not define to {}, since this breaks the common use of `YYDPRINTF 14459 ((...));' if a single statement is desired (e.g. before `else'). 14460 Work around GCC warnings by surrounding corresponding calls with 14461 {} if needed. 14462 (yyhasResolvedValue): Remove unused function. 14463 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty 14464 loop body. 14465 (yyreportSyntaxError): Renamed from yyreportParseError. 14466 (yyrecoverSyntaxError): Renamed from yyrecoverParseError. 14467 All uses changed. 14468 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of 14469 extern when possible.

Instead, use "$CC -E bar.c". Include the .h 14567 file twice in the grammar, as an extra check. 14568 14569 * tests/input.at (Torturing the Scanner): Surround the 14570 backslash-newline tests with "#if 0", to make it less likely that 14571 we'll run into compiler bugs.

(b4_yydestruct_generate, b4_symbol_actions): New. 14713 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c. 14714 Don't work on yychar (i.e., do set it to YYEMPTY, don't match 14715 it against

src/scan-gram.l (last_string): Is global to the file, not to 14742 yylex. 14743 * src/parse-gram.y (input): Don't append the epilogue here, 14744 (epilogue.opt): do it here, and free the scanner's obstack. 14745 * src/reader.c (epilogue_set): Rename as... 14746 (epilogue_augment): this. 14747 * data/c.m4 (b4_epilogue): Defaults to empty. 14748 14749 2002-11-12 Akim Demaille <akim (a] epita.fr>

struniq. 14779 14780 Use struniq for file names. 14781 14782 * src/files.h, src/files.c (infile): Split into... 14783 (grammar_file, current_file): these. 14784 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust. 14785 * src/reduce.c (reduce_print): Likewise. 14786 * src/getargs.c (getargs): Likewise. 14787 * src/complain.h, src/complain.c: Likewise. 14788 * src/main.c (main): Call

store it. 14803 * src/symtab.h (symbol_t): The 'type_name' member is a struniq. 14804 14805 2002-11-11 Paul Eggert <eggert (a] twinsun.com> 14806 14807 Revamp to fix many (but not all) of the C- and M4-related quoting 14808 problems. Among other things, this fixes the Bison bug reported 14809 by Jan Hubicka when processing the Bash grammar; see: 14810 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html> 14811 14812 Use new @ escapes consistently. Represent brackets with @{ and @} 14813 rather than @<:@ and @:>@, since this works a bit better with dumb 14814 editors like vi. Represent @ with @@, since @ is now consistently 14815 an escape. Use @oline@ and @ofile@ rather than __oline__ and 14816 __ofile__, to avoid unexpected expansions. Similarly, use @output 14817 rather than #output. 14818 14819 * data/c.m4 (b4_copyright): Omit file name from comment, since 14820 the file name could contain "*/". 14821 (b4_synclines_flag): Don't quote the 2nd argument; it should already 14822 be quoted. All uses changed. 14823 14824 * data/glr.c: Use new @ escapes consistently. 14825 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name, 14826 b4_output_header_suffix, b4_output_header_name, b4_header_guard): 14827 Remove, since they couldn't handle arbitrary characters in file 14828 names. 14829 * data/lalr1.cc: Likewise. 14830 * data/yacc.c: Likewise. 14831 14832 * src/files.c (output_infix): Remove; all uses removed. 14833 * src/files.h: Likewise. 14834 14835 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it 14836 mishandled funny characters in file names, and anyway it isn't 14837 needed any more. 14838 * data/yacc.c: Likewise. 14839 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard. 14840 14841 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would. 14842 * data/yacc.c: Likewise. 14843 14844 * src/muscle_tab.c: Include quotearg.h, since we need to quote C 14845 strings now. 14846 (muscle_init): Quote filename as a C string. 14847 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused. 14848 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros. 14849 * src/output.c (escaped_file_name_output): New function. 14850 (prepare_symbols): Quote tokens for M4. 14851 (prepare): Don't insert output_infix, output_prefix, 14852 output_parser_name, output_header_name; this is now down by scan-skel. 14853 Insert skeleton as a C string. 14854 14855 * src/output.c (user_actions_output, symbol_destructors_output, 14856 symbol_printers_output): Quote filenames for C and M4. 14857 * src/reader.c (prologue_augment, epilogue_set): Likewise. 14858 14859 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash 14860 escapes other than \\ and \'; this simplifies the code. 14861 (<SC_STRING>): Likewise, for \\ and \". 14862 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE, 14863 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too. 14864 Use new escapes @{ and @} for [ and ]. 14865 14866 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing 14867 them with auto vars. 14868 Switch to new escape scheme, where @ is the escape character uniformly. 14869 Abort if a stray escape character is found. Avoid unbounded input 14870 buffer when parsing non-escaped text. 14871 14872 * tests/input.at (Torturing the Scanner): Add tests that @oline@, 14873 __oline__, #output, $@, and @{ do not have unintended meanings. 14874 14875 2002-11-09 Paul Eggert <eggert (a] twinsun.com> 14876 14877 Fix the test failure due to GCC warnings described in 14878 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>. 14879 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which 14880 evaluate to 0 if it's impossible for NINF to be in the respective 14881 table. 14882 (yygetLRActions, yyrecoverParseError): Use them. 14883 14884 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were 14885 counted in the token inserted at end of file. Now takes 14886 location_t *, not location_t, so that the location can be 14887 adjusted. All uses changed. 14888 14889 * tests/regression.at (Invalid inputs): Adjust wording in 14890 diagnostic to match the new behavior. 14891 14892 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR, 14893 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR, 14894 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x)) 14895 abort ();'. This reduces the runtime of the "Many lookaheads" 14896 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running 14897 GCC 3.2. 14898 14899 2002-11-07 Paul Eggert <eggert (a] twinsun.com> 14900 14901 * src/parse-gram.y (CHARACTER): Remove unused token. 14902 All uses removed. 14903 14904 * src/scan-gram.l: Remove stack option. We no longer use the 14905 stack, since the stack was never deeper than 1; instead, use the 14906 new auto var c_context to record the stacked value. 14907 14908 Remove nounput option. At an unexpected end of file, we now unput 14909 the minimal input necessary to end cleanly; this simplifies the 14910 code. 14911 14912 Avoid unbounded token sizes where this is easy. 14913 14914 (unexpected_end_of_file): New function. 14915 Use it to systematize the error message on unexpected EOF. 14916 (last-string): Now auto, not static. 14917 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper. 14918 (scanner_last_string_free): Remove; not used. 14919 (percent_percent_count): Move decl to just before use. 14920 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file, 14921 not the (never otherwised-used) CHARACTER. 14922 14923 2002-11-07 Akim Demaille <akim (a] epita.fr> 14924 14925 Let yyerror always receive the msg as last argument, so that 14926 yyerror can be variadic. 14927 14928 * data/yacc.c (b4_yyerror_args): New. 14929 Use it when calling yyerror. 14930 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New. 14931 Use it when calling yyerror. 14932 * doc/bison.texinfo (Error Reporting): Adjust. 14933 * tests/calc.at (_AT_DATA_CALC_Y): Adjust. 14934 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust. 14935 14936 2002-11-06 Akim Demaille <akim (a] epita.fr> 14937 14938 #line should have quoted strings. 14939 Ideally, this should be done by m4_quotearg. 14940 14941 * src/scan-skel.l: Include quotearg.h. 14942 Quote __ofile__. 14943 * src/output.c (symbol_printers_output) 14944 (symbol_destructors_output): Quote the file name. 14945 14946 2002-11-06 Akim Demaille <akim (a] epita.fr> 14947 14948 * tests/regression.at (Invalid inputs): Adjust to the recent 14949 messages. 14950 14951 2002-11-06 Akim Demaille <akim (a] epita.fr> 14952 14953 Restore --no-lines. 14954 Reported by Jim Kent. 14955 14956 * data/c.m4 (b4_syncline): New. 14957 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it. 14958 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline. 14959 * src/output.c (user_actions_output): Likewise. 14960 (prepare): Define 'b4_synclines_flag'. 14961 * src/muscle_tab.c (muscle_init): Don't define b4_linef. 14962 14963 2002-11-06 Akim Demaille <akim (a] epita.fr> 14964 14965 * src/main.c (main): Free `infile'. 14966 * src/scan-gram.l (handle_syncline): New. 14967 Recognize `#line'. 14968 * src/output.c (user_actions_output, symbol_destructors_output) 14969 (symbol_printers_output): Use the location's file name, not 14970 infile. 14971 * src/reader.c (prologue_augment, epilogue_set): Likewise. 14972 14973 2002-11-05 Paul Hilfinger <Hilfinger (a] CS.Berkeley.EDU> 14974 14975 * src/tables.c (matching_state): Don't allow states to match if 14976 either has GLR conflict entries. 14977 14978 2002-11-05 Paul Eggert <eggert (a] twinsun.com> 14979 14980 * src/scan-gram.l: Use more accurate diagnostics, e.g. 14981 "integer out of range" rather than "invalid value". 14982 * tests/input.at (Invalid $n, Invalid @n): Change expected wording 14983 accordingly. 14984 14985 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires. 14986 Also, remove one static variable in the scanner. 14987 14988 * src/scan-gram.l (braces_level): Now auto, not static. 14989 Initialize to zero if the compiler is being picky. 14990 (INITIAL): Clear braces_level instead of incrementing it. 14991 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code, 14992 as POSIX 1003.1-2001 requires. 14993 * src/system.h (IF_LINT): New macro, taken from coreutils. 14994 * configure.ac: Define "lint" if --enable-gcc-warnings. 14995 14996 2002-11-05 Akim Demaille <akim (a] epita.fr> 14997 14998 * src/scan-gram.l: When it starts with `%', complain about the 14999 whole directive, not just that `invalid character: %'. 15000 15001 2002-11-04 Akim Demaille <akim (a] epita.fr> 15002 15003 *

yacc & pure & parse-param. 15013 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments. 15014 15015 2002-11-04 Akim Demaille <akim (a] epita.fr> 15016 15017 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid 15018 clashes. 15019 * src/scan-gram.l: Use [\'] instead of ['] to pacify 15020 font-lock-mode. 15021 Use complain_at. 15022 Use quote, not quote_n since LOCATION_PRINT no longer uses the 15023 slot 0. 15024 15025 2002-11-03 Paul Eggert <eggert (a] twinsun.com> 15026 15027 * src/reader.c (get_merge_function, grammar_current_rule_check): 15028 Use consistent diagnostics

b4_lpure_args) 15042 (b4_lpure_formals): New. 15043 Use b4_identification. 15044 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by 15045 b4_user_formals and b4_user_args. 15046 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer) 15047 (yyreportAmbiguity): When using a pure parser, also need 15048 the location, and the parse-params. 15049 Adjust callers. 15050 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError): 15051 When using a pure parser, also need the parse-params. 15052 Adjust callers. 15053 * tests/calc.at: Test pure (%pure-parser) and absolutely pure 15054 (%pure-parser + %parse-param) LALR and GLR parsers. 15055 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF, 15056 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

YY_USER_ACTION now counts newlines etc.; 15095 all uses changed. 15096 (tag, splice): New EREs. Do not allow NUL or newline in tags. 15097 Use {splice} wherever C allows backslash-newline. 15098 YY_STEP after space, newline, vertical-tab. 15099 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT). 15100 15101 (letter, id): Don't assume ASCII; e.g., spell out a-z. 15102 15103 ({int}, handle_action_dollar, handle_action_at): Check for integer 15104 overflow. 15105 15106 (YY_STEP): Omit trailing semicolon, so that it's more like C. 15107 15108 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00 15109 as well as \000. Check for UCHAR_MAX, not 255. 15110 Allow \x with an arbitrary positive number of digits, as in C. 15111 Check for overflow here. 15112 Allow \? and UCNs, for compatibility with C. 15113 15114 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision 15115 with quote slot used by complain_at. 15116 15117 * tests/input.at: Add tests for backslash-newline, m4 quotes 15118 in symbols, long literals, and funny escapes in strings. 15119 15120 * configure.ac (jm_PREREQ_MBSWIDTH): Add. 15121 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c. 15122 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext. 15123 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4. 15124 * m4/mbswidth.m4: New file, from GNU coreutils. 15125 15126 * doc/bison.texinfo (Grammar Outline): Document // comments. 15127 (Symbols): Document that trigraphs have no special meaning in Bison, 15128 nor is backslash-newline allowed. 15129 (Actions): Document that trigraphs have no special meaning. 15130 15131 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove; 15132 no longer used. 15133 15134 2002-11-02 Paul Eggert <eggert (a] twinsun.com> 15135 15136 * src/reader.c: Don't include quote.h; not needed. 15137 (get_merge_function): Reword warning to be consistent with 15138 type clash diagnostic in grammar_current_rule_check. 15139 15140 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two 15141 bug in trigraph handling. 15142 15143 * src/output.c (prepare_symbols): When printing token names, 15144 escape "[" as "@<:@" and likewise for "]". 15145 15146 * src/system.h (errno): Remove declaration, as we are now 15147 assuming C89 or better, and C89 guarantees errno. 15148 15149 2002-10-30 Paul Eggert <eggert (a] twinsun.com> 15150 15151 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write): 15152 Check for close failures. 15153 * src/files.h (xfclose): Return void, not int, since it always 15154 returned zero. 15155 * src/files.c (xfclose): Likewise. Report I/O error if ferror 15156 indicates one. 15157 * src/output.c (output_skeleton): Use xfclose rather than fclose 15158 and ferror. xfclose now checks ferror. 15159 15160 * data/glr.c (YYLEFTMOST_STATE): Remove. 15161 (yyreportTree): Use a stack-based leftmost state. This avoids 15162 our continuing battles with bogus warnings about initializers. 15163 15164 2002-10-30 Akim Demaille <akim (a] epita.fr> 15165 15166 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only 15167 #if. 15168 15169 2002-10-29 Paul Hilfinger <Hilfinger (a] CS.Berkeley.EDU> 15170 15171 * tests/glr-regr1.at: New test for reported regressions. 15172 * tests/testsuite.at: Add glr-regr1.at test. 15173 * tests/Makefile.am: Add glr-regr1.at test. 15174 15175 2002-10-24 Paul Eggert <eggert (a] twinsun.com> 15176 15177 Version 1.75a. 15178 15179 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration. 15180 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since 15181 we use malloc. Don't assume 'A' through 'Z' are contiguous. 15182 Don't assume strdup exists; POSIX says its an XSI extension. 15183 Check for buffer overflow on input. 15184 15185 2002-10-24 Akim Demaille <akim (a] epita.fr> 15186 15187 * src/output.c (output_skeleton): Don't disable M4sugar comments 15188 too soon: it results in comments being expanded. 15189 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the 15190 first output. 15191 15192 2002-10-24 Akim Demaille <akim (a] epita.fr> 15193 15194 * data/yacc.c (m4_int_type): New. 15195 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed 15196 char' as only yacc.c wants K&R portability. 15197 * data/glr.c (yysigned_char): Remove. 15198 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name. 15199 Reported by Quoc Peyrot. 15200 15201 2002-10-23 Paul Eggert <eggert (a] twinsun.com> 15202 15203 * src/main.c (main): With --trace=time, report times even if a 15204 non-fatal error occurs. Formerly, the times were reported in some 15205 such cases but not in others. 15206 * src/reader.c (reader): Just return if a complaint has been issued, 15207 instead of exiting, so that 'main' can report times. 15208 15209 2002-10-22 Akim Demaille <akim (a] epita.fr> 15210 15211 * src/system.h: Include sys/types. 15212 Reported by Bert Deknuydt. 15213 15214 2002-10-23 Paul Eggert <eggert (a] twinsun.com> 15215 15216 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX. 15217 Suggested by Art Haas. 15218 15219 2002-10-22 Paul Eggert <eggert (a] twinsun.com> 15220 15221 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit 15222 decl; not needed any more. 15223 * src/main.c (main): Use return to exit, undoing yesterday's change. 15224 The last OS that we could find where this wouldn't work is 15225 SunOS 3.5, and that's too old to worry about now. 15226 15227 * data/glr.c (struct yyltype): Define members even when not 15228 doing locations. This is more consistent with yacc.c, and it 15229 works around the following bug reports: 15230 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html 15231 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html 15232 15233 * doc/bison.texinfo: Minor spelling and typographical fixes. Use 15234 @acronym consistently. Standardize on "Yacc" instead of "YACC", 15235 "Algol" instead of "ALGOL".

FALSE : TRUE) -> (! a) 15249 * src/symtab.c (hash_compare_symbol_t): Likewise. 15250 * src/system.h (bool, false, true): Use a definition consistent 15251 with ../lib/hash.c. All uses changed. 15252 15253 * src/complain.c (warning_issued): Renamed from warn_message_count, 15254 so that we needn't worry about integer overflow (!). 15255 Now of type bool. All uses changed. 15256 (complaint_issued): Renamed from complain_message_count; likewise. 15257 15258 * src/main.c (main): Use exit to exit with failure. 15259 15260 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS 15261 rather than 1 and 0. 15262 * src/main.c (main): Likewise. 15263 * src/getargs.c (getargs): Likewise. 15264 * src/reader.c (reader): Likewise. 15265 15266 * src/getarg.c (getargs): Remove duplicate code for 15267 "Try `bison --help'". 15268 15269 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2. 15270 What was that "2" for? 15271 15272 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)). 15273 * src/getargs.c (usage): Likewise. 15274 15275 * src/getargs.c (getargs): When there are too few operands, report 15276 the last one. When there are too many, report the first extra 15277 one. This is how diffutils does it. 15278 15279 2002-10-20 Paul Eggert <eggert (a] twinsun.com> 15280 15281 Remove K&R vestiges. 15282 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove. 15283 * src/complain.c (VA_START): Remove.

Instead, divide into 1.0 rather than 1; 15379 this generates a more-accurate value anyway. 15380 15381 * lib/timevar.c (timervar_accumulate): Rename locals to 15382 avoid confusion with similarly-named more-global. 15383 * src/muscle_tab.c (muscle_pair_list_grow): Likewise. 15384 15385 * src/output.c (prepare): Use xstrdup to convert char const * 15386 to char *, to avoid GCC warning. 15387 15388 2002-10-19 Akim Demaille <akim (a] epita.fr> 15389 15390 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS, 15391 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS. 15392 Use them to have `calc.y' ready for %pure-parser. 15393 * data/yacc.c (YYLEX): Pass a yylex return type to 15394 b4_c_function_call. 15395 15396 2002-10-19 Akim Demaille <akim (a] epita.fr> 15397 15398 Prototype support of %lex-param and %parse-param. 15399 15400 * src/parse-gram.y: Add the definition of the %lex-param and 15401 %parse-param tokens, plus their rules. 15402 Drop the `_' version of %glr-parser. 15403 Add the "," token. 15404 * src/scan-gram.l (INITIAL): Scan them. 15405 * src/muscle_tab.c: Comment changes. 15406 (muscle_insert, muscle_find): Rename `pair' as `probe'. 15407 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused. 15408 (muscle_entry_s): The `value' member is no longer const. 15409 Adjust all dependencies. 15410 * src/muscle_tab.c (muscle_init): Adjust: use 15411 MUSCLE_INSERT_STRING. 15412 Initialize the obstack earlier. 15413 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow) 15414 (muscle_pair_list_grow): New. 15415 * data/c.m4 (b4_c_function_call, b4_c_args): New. 15416 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param. 15417 * tests/calc.at: Use %locations, not --locations. 15418 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser. 15419 15420 2002-10-19 Akim Demaille <akim (a] epita.fr> 15421 15422 * src/getargs.c (usage): Take status as argument and exit 15423 accordingly. 15424 Report the traditional `Try ... --help' message when status != 0. 15425 (usage, version): Don't take a FILE * as arg, it is pointless. 15426 (getargs): When there is an incorrect number of arguments, make it 15427 an error, and report it GNUlically thanks to `usage ()'. 15428 15429 2002-10-18 Paul Eggert <eggert (a] twinsun.com> 15430 15431 * data/glr.c (yyreportParseError): Don't assume that sprintf 15432 yields the length of the printed string, as this is not true 15433 on SunOS 4.1.4.

Sun C exits 16203 with status 2 sometimes. 16204 16205 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro. 16206 Use it for the two large tests. 16207 16208 2002-08-02 Akim Demaille <akim (a] epita.fr> 16209 16210 * src/conflicts.c (conflicts_output): Don't output rules never 16211 reduced here, since anyway that computation doesn't work. 16212 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p) 16213 (rule_useless_p, rule_never_reduced_p): New. 16214 (grammar_rules_partial_print): Use a filter instead of a range. 16215 Display the title only if needed. 16216

Report rules never reduced. 16225 * tests/conflicts.at, tests/reduce.at: Adjust. 16226 16227 2002-08-01 Akim Demaille <akim (a] epita.fr> 16228 16229 Instead of attaching lookaheads and duplicating

16258 Adjust all dependencies. 16259 * src/nullable.c (set_nullable, free_nullable): Rename as... 16260 (nullable_compute, nullable_free): these. 16261 (rule_list_t): Store rule_t *, not rule_number_t. 16262 * src/state.c (state_rule_lookaheads_print): Directly compare rule 16263 pointers, instead of their numbers. 16264 * src/main.c (main): Call nullable_free, and derives_free earlier, 16265 as they were lo longer used. 16266 16267 2002-08-01 Akim Demaille <akim (a] epita.fr> 16268 16269 * lib/timevar.c (get_time): Include children time. 16270 * src/lalr.h (LA, LArule):

allocates 16279 them. 16280 Don't free LA and LArule, main does. 16281 16282 2002-07-31 Akim Demaille <akim (a] epita.fr> 16283 16284 Separate parser tables computation and output. 16285 16286 *

(trace_args, trace_types, trace_argmatch): New. 16330 (long_options, short_options): --trace/-T takes an optional 16331 argument. 16332 Change all the uses of trace_flag to reflect the new flags. 16333 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets. 16334 16335 Strengthen `stage' portability. 16336 16337 * m4/stage.m4 (BISON_PREREQ_STAGE): New. 16338 * configure.in: Use

(Printers and Destructors): Adjust. 16349 * tests/calc.at (Calculator $1): Adjust. 16350 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose 16351 error message, do not report the parser accepts the error token in 16352 that state. 16353 16354 2002-07-30 Akim Demaille <akim (a] epita.fr> 16355 16356 Normalize conflict related messages. 16357 16358 * src/complain.h, src/complain.c

src/LR0.c (save_reductions): Don't make the final state too 16370 different: save its reduction (accept) instead of having a state 16371 without any action (no shift or goto, no reduce). 16372 Note: the final state is now a ``regular'' state, i.e., the 16373 parsers now contain `reduce 0' as default reduction. 16374 Nevertheless, since they decide to `accept' when yystate = 16375 final_state,

Demaille <akim (a] epita.fr> 16391 16392 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not 16393 state_number_t. 16394 (errs_t): symbol_t*, not symbol_number_t. 16395 (reductions_t): rule_t*, not rule_number_t. 16396 (FOR_EACH_SHIFT): New. 16397 * src/LR0.c, src/conflicts.c, src/lalr.c, src/output.c 16398 * src/print.c, src/print_graph.c: Adjust. 16399 16400 2002-07-29 Akim

the start symbol, not the axiom. 16415 Use its location. 16416 * tests/reduce.at (Empty Language): New. 16417 16418 2002-07-26 Akim Demaille <akim (a] epita.fr> 16419 16420 * src/reader.h, src/reader.c (gram_error): ... can't get 16421 yycontrol without making too strong assumptions on the parser 16422 itself. 16423 * src/output.c (prepare_tokens): Use the real 0th value of 16424 token_translations instead of `0'. 16425 * src/parse-gram.y (yyerror): Don't rely on yycontrol being 16426 visible here. 16427 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc 16428 for the time being: %locations ought to provide it to yyerror. 16429 16430 2002-07-25 Akim Demaille <akim (a] epita.fr> 16431 16432 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

Allocate and free from &rules[0], not &rules[1]. 16443 Iterate from 0 to nrules. 16444 Use rule_number_as_item_number and item_number_as_rule_number. 16445 Adjust to `derive' now containing possibly 0. 16446 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number): 16447 Handle the `- 1' part in rule numbers from/to item numbers. 16448 * src/conflicts.c (log_resolution): Fix the message which reversed 16449 shift and reduce. 16450 * src/output.c (action_row): Initialize default_rule to -1. 16451 (token_actions): Adjust. 16452 * tests/sets.at (Nullable, Firsts): Fix the

using attrs_obstack unconditionally. 18037 (read_declarations): Pass pre_prologue_obstack to copy_definition if 18038 `%union' has not yet been seen, pass post_prologue_obstack otherwise. 18039 18040

defined (YYERROR_VERBOSE). 18045 18046 (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY, 18047 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or 18048 if this is a C++ parser and

tests/regression.at (Web2c Actions): Adjust. 18079 18080 2002-04-22 Akim Demaille <akim (a] epita.fr> 18081 18082 * src/reader.c (token_translations_init): 256 is now the default 18083 value for the error token, i.e., it will be assigned another 18084 number if the user assigned 256 to one of her tokens. 18085 (reader): Don't force 256 to error. 18086 * doc/bison.texinfo (Symbols): Adjust. 18087 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR) 18088 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3 18089 etc. instead of 10, 20, 30 (which was used to `jump' over error 18090 (256) and

2002-04-09 Akim Demaille <akim (a] epita.fr> 18128 18129 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the 18130 full stderr, and strip it according to the bison options, instead 18131 of composing the error message from different bits. 18132 This makes it easier to check for several error messages. 18133 Adjust all the invocations. 18134 Add an invocation exercising the error token. 18135 Add an invocation demonstrating a stupid error message. 18136 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0. 18137 Adjust the tests. 18138 Error message are for stderr, not stdout. 18139 18140 2002-04-09 Akim Demaille <akim (a] epita.fr> 18141 18142 * src/gram.h, src/gram.c (error_token_number): Remove, use 18143 errtoken->number. 18144 * src/reader.c (reader): Don't

token_number_t. 18149 * src/print.c, src/reader.c: Use undeftoken->number instead of 18150 hard coded 2. 18151 (Even though this 2 is not the same as above: the number of the 18152 undeftoken remains being 2, it is its user token number which 18153 might not be 2). 18154 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with 18155 `user_token_number_max'. 18156 Output `undef_token_number'. 18157 * data/bison.simple, data/bison.c++: Use them. 18158 Be sure to map invalid yylex return values to 18159 `undef_token_number'.

Note that it must be able to code symbol numbers as 18179 positive number, and the negation of rule numbers as negative 18180 numbers. 18181 Adjust all dependencies (pretty many). 18182 * src/reduce.c (rule): Remove this `short *' pointer: use 18183 item_number_t. 18184 * src/system.h (MINSHORT, MAXSHORT): Remove. 18185 Include `limits.h'. 18186 Adjust dependencies to using SHRT_MAX and SHRT_MIN. 18187 (shortcpy): Remove. 18188 (MAXTABLE): Move to... 18189 * src/output.c (MAXTABLE): here. 18190 (prepare_rules): Use output_int_table to output rhs. 18191 * data/bison.simple, data/bison.c++: Adjust. 18192 * tests/torture.at (Big triangle): Move the limit from 254 to 18193 500. 18194 * tests/regression.at (Web2c Actions): Ajust. 18195 18196 Trying with bigger grammars shows various

This can wait 18704 for a proper C++ parser. 18705 18706 * NEWS: Document this. 18707 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention 18708 of C++, as it's treated like C now. 18709 * src/bison.simple (YYSTD): Remove. 18710 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL): 18711 Treat C++ just like Standard C instead of trying to support 18712 namespace cleanliness. 18713 18714 2002-02-14 Akim Demaille <akim (a] epita.fr> 18715 18716 * tests/regression.at (else): Adjust to Andreas' change. 18717 18718 2002-02-14 Akim Demaille <akim (a] epita.fr> 18719 18720 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c. 18721 18722 2002-02-13 Andreas Schwab <schwab (a] suse.de> 18723 18724 * src/output.c (output_rule_data): Don't output NULL, it might 18725 not be defined yet. 18726 18727 2002-02-11 Robert Anisko <robert (a] lrde.epita.fr> 18728 18729 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue. 18730 (Copyright notice): Update. 18731 18732 2002-02-11 Akim Demaille <akim (a] epita.fr> 18733 18734 * tests/regression.at (%nonassoc and eof): Don't include 18735 nonportable headers. 18736 18737 2002-02-08 Robert Anisko <robert (a] lrde.epita.fr> 18738 18739 * data/bison.c++: Correct error recovery.

This is temporary, a proper temporary 18802 file will be used. 18803 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton. 18804 (prepare): Given that for the time being changesyntax is not 18805 usable in M4, rename the muscles using `-' to `_'. 18806 Define `defines_flag', `output_parser_name' and `output_header_name'. 18807 * src/output.h (actions_output, guards_output) 18808 (token_definitions_output): Adjust prototypes. 18809 * src/scan-skel.l: Instead of scanning the skeletons, it now 18810 processes the output of m4: `__oline__' and `#output'. 18811 * data/bison.simple: Adjust to be used by M4(sugar). 18812 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up 18813 to date. 18814 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR' 18815 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'. 18816 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New, 18817 shamelessly stolen from CVS Autoconf. 18818 18819 2002-02-05 Akim Demaille <akim (a] epita.fr> 18820 18821 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version. 18822 * configure.in: Check for the declarations of free and malloc. 18823 * src/muscle_tab.c: Adjust. 18824 18825 2002-02-05 Akim Demaille <akim (a] epita.fr> 18826 18827 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle 18828 which have no values. 18829 18830 2002-02-05 Akim Demaille <akim (a] epita.fr> 18831 18832 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to... 18833 * data/: here. 18834 18835 2002-01-29 Paul Eggert <eggert (a] twinsun.com> 18836 18837 * src/bison.simple (YYSIZE_T): Do not define merely because 18838 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined. 18839 On some platforms, <alloca.h> does not declare YYSTD (size_t). 18840 18841 2002-01-27 Akim Demaille <akim (a] epita.fr> 18842 18843 Fix `%nonassoc and eof'. 18844 18845 * src/state.c (errs_dup): Aaaah! The failure was due to bytes 18846 which were not properly copied! Replace 18847 memcpy (res->errs, src->errs, src->nerrs); 18848 with 18849 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0])); 18850 !!! 18851 * tests/regression.at (%nonassoc and eof):

New test. 18901 * src/files.c (compute_base_names): Don't map extensions when 18902 the YACC flag is set, use defaults. 18903 Reported by Evgeny Stambulchik. 18904 18905 2002-01-20 Marc Autret <marc (a] gnu.org> 18906 18907 * src/system.h: Need to define __attribute__ away for non-GCC 18908 compilers as well (i.e., the vendor C compiler). 18909 Suggested by Albert Chin-A-Young. 18910 18911 2002-01-11 Tim Van Holder <tim.van.holder (a] pandora.be> 18912 18913 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the 18914 canonical definition. 18915 * src/system.h: Use the canonical definition for PARAMS (avoids 18916 a conflict with the macro from lib/hash.h). 18917 18918 2002-01-11 Akim Demaille <akim (a] epita.fr> 18919 18920 * configure.in: Use AC_FUNC_STRNLEN. 18921 Fixes

src/files.c: Fix a few warnings. 18943 (get_extension_index): Remove, unused. 18944 18945 2002-01-08 Akim Demaille <akim (a] epita.fr> 18946 18947 * src/getargs.c (AS_FILE_NAME): New. 18948 (getargs): Use it to convert DOSish file names. 18949 * src/files.c (base_name): Rename as full_base_name to avoid 18950 clashes with `base_name ()'. 18951 (filename_split): New. 18952 (compute_base_names): N-th rewrite, using filename_split. 18953 18954 2002-01-08 Akim Demaille <akim (a] epita.fr> 18955 18956 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c: 18957 New, stolen from the Fileutils 4.1. 18958 * lib/Makefile.am (libbison_a_SOURCES): Adjust. 18959 * configure.in: Check for the presence of memrchr, and of its 18960 prototype. 18961 18962 2002-01-07 Tim Van Holder <tim.van.holder (a] pandora.be> 18963 18964 * lib/hash.h (__P): Added definition for this macro. 18965 * src/Makefile.am: Add parse-skel.c and scan-skel.c to 18966 BUILT_SOURCES, to ensure they are generated first. 18967 * src/parse-skel.y: Use YYERROR_VERBOSE instead of 18968 %error-verbose to allow bootstrapping with bison 1.30x. 18969 18970 2002-01-06 Akim Demaille <akim (a] epita.fr> 18971 18972 * src/reader.c (parse_braces): Don't fetch the next char, the 18973 convention is to fetch on entry. 18974 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird 18975 'switch' without a following semicolon. 18976 * tests/regression.at (braces parsing): New. 18977 18978 2002-01-06 Akim Demaille <akim (a] epita.fr> 18979 18980 Bison is dead wrong in its RR conflict reports. 18981 18982

causes too many problems. 18988 18989 * tests/Makefile.am (package.m4): Create it by hand, 18990 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf. 18991 18992 2002-01-06 Akim Demaille <akim (a] epita.fr> 18993 18994 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and 18995 skeleton.h. 18996 18997 2002-01-04 Paul Eggert <eggert (a] twinsun.com> 18998 18999 * doc/bison.texinfo (Debugging): 19000 Remove YYSTDERR; it's no longer defined or used. 19001 Also, s/cstdio.h/cstdio/. 19002 19003 2002-01-03 Akim Demaille <akim (a] epita.fr> 19004 19005 * tests/bison.in,

C++ standard is extremely clear about it: stderr is 19017 considered a macro, not a regular symbol (see table 94 `Header 19018 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files). 19019 Therefore std:: does not apply to it. It still does with fprintf. 19020 Also, s/cstdio.h/cstdio/. 19021 19022 2002-01-03 Akim Demaille <akim (a] epita.fr> 19023 19024 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>' 19025 for non system headers. 19026 19027 2002-01-02 Akim Demaille <akim (a] epita.fr> 19028 19029 Equip the skeleton chain with location tracking, runtime trace, 19030 pure parser and scanner. 19031 19032 * src/parse-skel.y: Request a pure parser, locations, and prefix 19033 renaming. 19034 (%union): Having several members with the same type does not help 19035 type mismatches, simplify. 19036 (YYPRINT, yyprint): New. 19037 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as... 19038 (skel_error): this. 19039 Handle locations. 19040 * src/scan-skel.l: Adjust to these changes. 19041 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP) 19042 (LOCATION_PRINT, skel_control_t): New. 19043 19044 2001-12-30 Akim Demaille <akim (a] epita.fr> 19045 19046 * src/parse-skel.y: Get rid of the shift/reduce conflict: 19047 replace `gb' with BLANKS. 19048 * src/scan-skel.l: Adjust. 19049 19050 2001-12-30 Akim Demaille <akim (a] epita.fr> 19051 19052 * src/system.h: We don't need nor want bcopy. 19053 Throw away MS-DOS crap: we don't need getpid. 19054 * configure.in: We don't need strndup. It was even causing 19055 problems: because Flex includes the headers *before* us, 19056 _GNU_SOURCE is not defined by config.h, and therefore strndup was 19057 not visible. 19058 * lib/xstrndup.c: New. 19059 * src/scan-skel.l: Use it. 19060 Be sure to initialize yylval.muscle member when scanning a MUSCLE. 19061 * src/parse-skel.y: Use %directives instead of #defines. 19062 19063 2001-12-30 Akim Demaille <akim (a] epita.fr> 19064 19065 * src/skeleton.h: New. 19066 * src/output.c (output_parser, output_master_parser): Remove, dead 19067 code. 19068 * src/output.h (get_lines_number, actions_output, guards_output) 19069 (token_definitions_output): Prototype them. 19070 * src/parse-skel.y: Add the license notice. 19071 Include output.h and skeleton.h. 19072 (process_skeleton): Returns void, and takes a single parameter. 19073 * src/scan-skel.l: Add the license notice. 19074 Include skeleton.h. 19075 Don't use %option yylineno: it seems that then Flex imagines 19076 REJECT has been used, and therefore it won't reallocate its 19077 buffers (which makes no other sense to me than a bug). It results 19078 in warnings for `unused: yy_flex_realloc'. 19079 19080 2001-12-30 Robert Anisko <robert.anisko (a] epita.fr> 19081 19082 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) 19083 (MUSCLE_INSERT_PREFIX): ...to there. 19084 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) 19085 (MUSCLE_INSERT_PREFIX): Move from here... 19086 19087 * src/bison.hairy: Add a section directive.

See below. 19365 Use -1 as separator, not 0. 19366 * src/bison.simple (yyparse): Subtract 1 to the rule numbers. 19367 Rely on -1 as separator in yyrhs, instead of 0. 19368 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue 19369 twice `Now at end of input', therefore there are two lines less to 19370 expect. 19371 19372 2001-12-27 Akim Demaille <akim (a] epita.fr> 19373 19374 * tests/regression.at (Unresolved SR Conflicts): 19375 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes 19376 below. 19377 19378 2001-12-27 Akim Demaille <akim (a] epita.fr> 19379 19380 * src/LR0.c (new_state): Recognize the final state by the fact it 19381 is reached by eoftoken. 19382 (insert_start_shifting_state, insert_eof_shifting_state) 19383 (insert_accepting_state, augment_automaton): Remove, since now 19384 these states are automatically computed from the initial state. 19385 (generate_states): Adjust. 19386 * src/print.c: When reporting a rule number to the user, subtract 19387 1, so that the axiom rule is rule 0, and the first user rule is 1. 19388 * src/reduce.c: Likewise. 19389 * src/print_graph.c (print_core): For the time being, just as for 19390 the report, depend upon --trace-flags to dump the full set of 19391 items. 19392 * src/reader.c (readgram): Once the grammar read, insert the rule 19393 0: `$axiom: START-SYMBOL $'. 19394 * tests/set.at: Adjust: rule 0 is now displayed, and since the 19395 number of the states has changed (the final state is no longer 19396 necessarily the last), catch up. 19397 19398 2001-12-27 Akim Demaille <akim (a] epita.fr> 19399 19400 Try to make the use of the eoftoken valid.

token. 19427 * src/regression.at: Adjust: `$' has value 0, not -1, which was a 19428 lie anyway, albeit pleasant. 19429 * tests/calc.at: Exercise error messages with eoftoken. 19430 Change the grammar so that empty input is invalid. 19431 Adjust expectations. 19432 When yyungeting, be sure to use a valid yylloc: use last_yylloc. 19433 19434 2001-12-27 Akim Demaille <akim (a] epita.fr> 19435 19436 *

holds exactly nstates. 19552 * src/lalr.c (nLA): New. 19553 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it 19554 instead of lookaheadsp from the pseudo state (nstate + 1). 19555 19556 2001-12-27 Akim Demaille <akim (a] epita.fr> 19557 19558 * src/output.c (action_row, token_actions): Use a state_t instead 19559 of a integer, and nlookaheads instead of the following state's

19566 (count_sr_conflicts, count_rr_conflicts, conflicts_output) 19567 (conflicts_print, print_reductions): Use a state_t instead of an 19568 integer when referring to a state. 19569 As much as possible, depend upon nlookaheads, instead of the 19570 `lookaheadsp' member of the following state (since lookaheads of 19571 successive states are successive, the difference between state n + 1 19572 and n served as the number of lookaheads for state n). 19573 * src/lalr.c (add_lookback_edge): Likewise. 19574 * src/print.c (print_core, print_actions, print_state) 19575 (print_results):

19588 19589 * src/output.c (prepare): Drop the muscle `ntbase' which 19590 duplicates ntokens. 19591 * src/bison.simple: Formatting/comment changes. 19592 Use YYNTOKENS only, which is documented, but not YYNTBASE, which 19593 is an undocumented synonym. 19594 19595 2001-12-22 Akim Demaille <akim (a] epita.fr> 19596 19597 * src/output.c (output_table_data): Change the prototype to use 19598 `int' for array ranges: some invocations do pass an int, not a 19599 short. 19600 Reported by Wayne Green. 19601 19602 2001-12-22 Akim Demaille <akim (a] epita.fr> 19603 19604 Some actions of web2c.y are

Then, they are not processed properly. 19840 Admittedly an Autotest bug, but we don't have time to wait for 19841 Autotest to catch up. 19842 * tests/regression.at (Broken Closure): Adjust to the new table 19843 frames. 19844 Move to... 19845 * tests/sets.at: here. 19846 19847 2001-12-13 Akim Demaille <akim (a] epita.fr> 19848 19849 * src/closure.c (closure): Use nrules instead of playing tricks 19850 with BITS_PER_WORD. 19851 19852 2001-12-13 Akim Demaille <akim (a] epita.fr> 19853 19854 * src/print.c (print_actions): Output the handling of `$' as the 19855 traces do: shifting the token EOF. Before EOF was treated as a 19856 nonterminal. 19857 * tests/regression.at: Adjust some tests. 19858 * src/print_graph.c (print_core): Complete the set of items via 19859 closure. The next-to-final and final states are still unsatisfying, 19860 but that's to be addressed elsewhere. 19861 No longer output the rule numbers, but do output the state number. 19862 A single loop for the shifts + gotos is enough, but picked a 19863 distinct color for each. 19864 (print_graph): Initialize and finalize closure. 19865 19866 2001-12-13 Akim Demaille <akim (a] epita.fr> 19867 19868 * src/reader.c (readgram): Remove dead code, an strip useless 19869 braces. 19870 (get_type): Remove, unused. 19871 19872 2001-12-12 Akim Demaille <akim (a] epita.fr> 19873 19874 * src/complain.h, src/complain.c: Remove error_one_per_line, rely 19875 on that of lib/error.c. 19876 19877 2001-12-12 Akim Demaille <akim (a] epita.fr> 19878 19879 Some hosts don't like `/' in includes. 19880 19881 * src/system.h: Include libgettext.h without qualifying the path. 19882 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove 19883 $(top_srcdir). 19884 19885 2001-12-11 Marc Autret <autret_m (a] epita.fr> 19886 19887 * src/output.c (output_parser): Remove useless muscle. 19888 19889 2001-12-11 Marc Autret <autret_m (a] epita.fr> 19890 19891 * src/bison.simple: Remove #line just before %%epilogue.

But now, 19930 since shifts are attached, it is no longer needed to looking 19931 merely by its id: its number. 19932 19933 2001-12-10 Akim Demaille <akim (a] epita.fr> 19934 19935 * src/LR0.c (augment_automaton): Better variable locality. 19936 Remove an impossible branch: if there is a state corresponding to 19937 the start symbol being shifted, then there is shift for the start 19938 symbol from the initial state. 19939 19940 2001-12-10 Akim Demaille <akim (a] epita.fr> 19941 19942 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state' 19943 only when appropriate: when insert_start_shifting_state' is not 19944 invoked. 19945 * tests/regression.at (Rule Line Numbers): Adjust. 19946 19947 2001-12-10 Akim Demaille <akim (a] epita.fr> 19948 19949 * src/LR0.c

Instead of assigning shifts to 19971 state, just assert that the mapping was properly done. 19972 19973 2001-12-10 Akim Demaille <akim (a] epita.fr> 19974 19975 * src/LR0.c (insert_start_shift):

When looking if the start_symbol is shifted from the initial 19981 state, using `while (... symbol != start_symbol ...)' sounds 19982 better than `while (... symbol < start_symbol ...)': If fail 19983 to see how the order between symbols could be relevant! 19984 19985 2001-12-10 Akim Demaille <akim (a] epita.fr> 19986 19987 * src/getargs.h: Don't declare `spec_name_prefix' and 19988 `spec_file_prefix', declared by src/files.h. 19989 * src/files.c, src/files.h: Default for spec_name_prefix is "yy". 19990 * src/muscle_tab.c (muscle_init): Default prefix to NULL. 19991 *

19997 * src/muscle_tab.c (muscle_init): NULL is a better default than 19998 `"0"'. 19999 20000 2001-12-10 Akim Demaille <akim (a] epita.fr> 20001 20002 * src/reader.c (reader): Calling symbols_output once is enough. 20003 20004 2001-12-10 Akim Demaille <akim (a] epita.fr> 20005 20006 Now that states have a complete set of members, the linked list of 20007 reductions is useless: just fill directly the state's reductions 20008 member. 20009 20010 * src/state.h (struct reductions): Remove member `number' and 20011 `next'. 20012 * src/LR0.c (first_reduction, last_reduction): Remove. 20013 (save_reductions): Don't link the new reductions, store them in 20014 this_state. 20015 * src/lalr.c (set_state_table): No need to attach reductions to 20016 states, it's already done. 20017 * src/output.c (output_actions): No longer free the shifts, then 20018 the reductions, then the states: free all the states and their 20019 members. 20020 20021 2001-12-10 Akim Demaille <akim (a] epita.fr> 20022 20023 * src/options.c (OPTN, DRTV, BOTH): New. 20024 (option_table): Use them. 20025 20026 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's 20027 the job of system.h. 20028 * src/options.c: Don't include stdio.h and xalloc.h for the same 20029 reasons. 20030 20031 2001-12-10 Akim Demaille <akim (a] epita.fr> 20032 20033 * src/output.c (output, prepare): Make sure the values of the 20034 muscles `action' and `prologue' are 0-terminated. 20035 20036 2001-12-10 Akim Demaille <akim (a] epita.fr> 20037 20038 Clean up GCC warnings. 20039 20040 * src/reader.c (copy_action): `buf' is not used. 20041 (parse_skel_decl): Be static. 20042 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'. 20043 * src/options.h (create_long_option_table): Have a real prototype. 20044 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete) 20045 (hash_delete_at): Return const void *. 20046 Adjust casts to preserve the const. 20047 20048 2001-12-10 Akim Demaille <akim (a] epita.fr> 20049 20050 * configure.in: Require 2.52g. 20051 M4 is not needed, but AUTOM4TE is. 20052 * m4/m4.m4: Remove. 20053 * tests/Makefile.am: Adjust. 20054 20055 2001-12-10 Akim Demaille <akim (a] epita.fr> 20056 20057 One structure for states is enough, even though theoretically 20058 there are LR(0) states and LALR(1) states. 20059 20060 * src/lalr.h (state_t): Remove. 20061 (state_table): Be state_t **, not state_t *. 20062 * src/state.h (core, CORE_ALLOC): Rename as... 20063 (state_t, STATE_ALLOC): this. 20064 Add the LALR(1) members: shifts, reductions, errs. 20065 * src/LR0.c (state_table): Rename as... 20066 (state_hash): this, to avoid name clashes with the global 20067 `state_table'. 20068 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c 20069 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust. 20070 20071 2001-12-10 Akim Demaille <akim (a] epita.fr> 20072 20073 Bison dumps core on bash.y. 20074 Reported by Pascal Bart. 20075 20076 * src/warshall.c (bitmatrix_print): New. 20077 (TC): Use it. 20078 When performing a transitive closure R(i, j) && R(j, k) => R(i, k), 20079 j must be the outer loop. 20080 * tests/regression.at (Broken Closure): New. 20081 20082 2001-12-05 Akim Demaille <akim (a] epita.fr> 20083 20084 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and 20085 its argument. 20086 Reported by Peter Hamorsky. 20087 20088 2001-12-05 Akim Demaille <akim (a] epita.fr> 20089 20090 * src/conflicts.c (err_table): Remove. 20091 (resolve_sr_conflict): Adjust. 20092 * src/lalr.h (state_t.reduction_table, state_t.shift_table): 20093 Rename as... 20094 (state_t.reductions, state_t.shifts): this. 20095 20096 2001-12-05 Akim Demaille <akim (a] epita.fr> 20097 20098 * src/reduce.c (reduce_grammar_tables): No longer disable the 20099 removal of useless rules via CPP but via `if (0)', so that the 20100 compiler still check the code is valid. 20101 For instance, it should have noticed `rline' no longer exists: use 20102 the `line' member of rule_t. 20103 * src/gram.c (dummy, rline): Remove, unused. 20104 20105 2001-12-05 Akim Demaille <akim (a] epita.fr> 20106 20107 * src/output.c (pack_vector): Use assert, not berror. 20108 * src/main.c (berror): Remove, unused. 20109 20110 2001-12-05 Akim Demaille <akim (a] epita.fr> 20111 20112 New experimental feature: if --verbose --trace output all the 20113 items of a state, not only its kernel. 20114 20115 * src/print.c (print_core): If `trace_flag', then invoke closure 20116 before outputting the items of the state (print_core is no longer 20117 a correct name them). 20118 (print_results): Invoke new_closure/free_closure if needed. 20119 20120 2001-12-05 Akim Demaille <akim (a] epita.fr> 20121 20122 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount. 20123 * src/closure.c, src/closure.h (itemsetsize): Rename as... 20124 (nitemset): for consistency with the rest of the project. 20125 20126 2001-12-05 Akim Demaille <akim (a] epita.fr> 20127 20128 * src/closure.c (print_closure): Improve. 20129 (closure): Use it for printing input and output. 20130 20131 2001-12-05 Akim Demaille <akim (a] epita.fr> 20132 20133 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are 20134 indexed by nonterminals. 20135 20136 2001-12-05 Akim Demaille <akim (a] epita.fr> 20137 20138 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of 20139 what it was!). 20140 * src/warshall.h: Remove accidental duplication of the content. 20141 20142 2001-12-05 Akim Demaille <akim (a] epita.fr> 20143 20144 * src/closure.c (set_fderives): De-obfuscate. 20145 20146 2001-12-05 Akim Demaille <akim (a] epita.fr> 20147 20148 * src/closure.c (print_firsts, print_fderives): De-obfuscate. 20149 20150 2001-12-05 Akim Demaille <akim (a] epita.fr> 20151 20152 * src/closure.c (set_firsts): De-obfuscate. 20153 20154 2001-12-05 Akim Demaille <akim (a] epita.fr> 20155 20156 * src/output.c (action_row): De-obfuscate 20157 using the good o' techniques: arrays not pointers, variable 20158 locality, BITISSET, RESETBIT etc. 20159 20160 2001-12-05 Akim Demaille <akim (a] epita.fr> 20161 20162 Pessimize the code to simplify it: from now on, all the states 20163 have a valid SHIFTS, which NSHIFTS is possibly 0. 20164 20165 * src/LR0.c (shifts_new): Be global and move to.. 20166 * src/state.c, src/state.h: here. 20167 * src/conflicts, src/lalr.c, src/output.c, src/print.c, 20168 * src/print_graph: Adjust. 20169 20170 2001-12-05 Akim Demaille <akim (a] epita.fr> 20171 20172 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New. 20173 * src/conflicts.c: Use it. 20174 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were 20175 incorrectly ``simplified''. 20176 20177 2001-12-05 Akim Demaille <akim (a] epita.fr> 20178 20179 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate 20180 using the good o' techniques: arrays not pointers, variable 20181 locality, BITISSET, RESETBIT etc. 20182 20183 2001-12-05 Akim Demaille <akim (a] epita.fr> 20184 20185 * src/state.h (SHIFT_SYMBOL): New. 20186 * src/conflicts.c: Use it to deobfuscate. 20187 20188 2001-12-05 Akim Demaille <akim (a] epita.fr> 20189 20190 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts) 20191 (print_reductions): De-obfuscate using the good o' techniques: 20192 arrays not pointers, variable locality, BITISSET. 20193 20194 2001-12-05 Akim Demaille <akim (a] epita.fr> 20195 20196 * src/conflicts.c (print_reductions): Arrays, not pointers. 20197 Use BITISSET. 20198 20199 2001-12-05 Akim Demaille <akim (a] epita.fr> 20200 20201 * src/conflicts.c (print_reductions): Pessimize, but clarify. 20202 20203 2001-12-05 Akim Demaille <akim (a] epita.fr> 20204 20205 * src/conflicts.c (print_reductions): Improve variable locality. 20206 20207 2001-12-05 Akim Demaille <akim (a] epita.fr> 20208 20209 * src/conflicts.c (print_reductions): Pessimize, but clarify. 20210 20211 2001-12-05 Akim Demaille <akim (a] epita.fr> 20212 20213 * src/conflicts.c (print_reductions): Improve variable locality. 20214 20215 2001-12-05 Akim Demaille <akim (a] epita.fr> 20216 20217 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New. 20218 * src/lalr.c: Use them. 20219 20220 2001-12-05 Akim Demaille <akim (a] epita.fr> 20221 20222 * src/LR0.c (augment_automaton): Formatting changes. 20223 Better variable locality. 20224 20225 2001-12-05 Akim Demaille <akim (a] epita.fr> 20226 20227 * src/lalr.c (matrix_print): New. 20228 (transpose): Use it. 20229 Use arrays instead of pointers. 20230 20231 2001-12-05 Akim Demaille <akim (a] epita.fr> 20232 20233 * src/lalr.c (maxrhs): Move to... 20234 * src/gram.c, src/gram.h (ritem_longest_rhs): here. 20235 * src/lalr.c (build_relations): Adjust. 20236 20237 2001-12-05 Akim Demaille <akim (a] epita.fr> 20238 20239 * src/lalr.c (transpose): Free the memory allocated to the 20240 argument, as it is replaced by the results by the unique caller. 20241 (build_relations): Merely invoke transpose: it handles the memory 20242 deallocation. 20243 Improve variable locality. 20244 Avoid variables used as mere abbreviations. 20245 (compute_lookaheads): Use arrays instead of pointers. 20246 20247 2001-12-05 Akim Demaille <akim (a] epita.fr> 20248 20249 * src/lalr.c (initialize_F): Improve variable locality. 20250 Avoid variables used as mere abbreviations. 20251 20252 2001-12-05 Akim Demaille <akim (a] epita.fr> 20253 20254 * src/derives.c (print_derives): Display the ruleno. 20255 * src/lalr.c (initialize_F, transpose): Better variable locality 20256 to improve readability. 20257 Avoid variables used as mere abbreviations. 20258 20259 2001-12-05 Akim Demaille <akim (a] epita.fr> 20260 20261 * src/lalr.c (traverse): Use arrays instead of pointers. 20262 20263 2001-12-05 Akim Demaille <akim (a] epita.fr> 20264 20265 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate 20266 the handling of squeue. 20267 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'. 20268 20269 2001-12-05 Akim Demaille <akim (a] epita.fr> 20270 20271 Because useless nonterminals are now kept alive (instead of being 20272 `destroyed'), we now sometimes examine them, and store information 20273 related to them. Hence we need to know their number, and adjust 20274 memory allocations. 20275 20276 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer 20277 static. 20278 * src/LR0.c (allocate_itemsets): The memory allocated to 20279 `symbol_count' was used for two different purpose: once to count 20280 the number of occurrences of each symbol, and later reassigned to 20281 `shift_symbol', containing the symbol that can be shifted from a 20282 given state. 20283 Deobfuscate, i.e., allocate, use and free `symbol_count' here 20284 only, and... 20285 (new_itemsets): Allocate `shift_symbol' here. 20286 (allocate_itemsets): symbol_count includes useless nonterminals. 20287 Make room for them. 20288 (free_storage): Use `free', not `XFREE', for pointers that cannot 20289 be null. 20290 20291 2001-12-05 Akim Demaille <akim (a] epita.fr> 20292 20293 * src/nullable.c (set_nullable): Deobfuscate the handling of 20294 ritem. 20295 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'. 20296 20297 2001-12-05 Akim Demaille <akim (a] epita.fr> 20298 20299 * src/gram.c, src/gram.h (ritem_print): New. 20300 * src/gram.c (dummy): Remove, now there is actual code in gram.c. 20301 (This useless function was defined only to work around VMS linkers 20302 that can't handle compilation units with variables only). 20303 * src/reduce.c (dump_grammar): Use it to trace the construction of 20304 ritem. 20305 20306 2001-12-04 Paul Eggert <eggert (a] twinsun.com> 20307 20308 * src/bison.simple (union yyalloc): Change member names 20309 to be the same as the stack names. 20310 (yyparse): yyptr is now union yyalloc *, not char *. 20311 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning, 20312 and may generate better code on some machines. 20313 (yystpcpy): Use prototype if __STDC__ is defined, not just 20314 if __cplusplus is defined. 20315 20316 2001-11-30 Akim Demaille <akim (a] epita.fr> 20317 20318 * configure.in (WARNING_CFLAGS): Add -Werror when possible. 20319 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU 20320 Gettext doesn't compile cleanly, and dies with -Werror. 20321 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS): 20322 Include WARNING_CFLAGS here. 20323 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared 20324 before being defined. 20325 20326 2001-11-27 Paul Eggert <eggert (a] twinsun.com> 20327 20328 * lib/quotearg.h (quotearg_n, quotearg_n_style): 20329 First arg is int, not unsigned. 20330 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise. 20331 (SIZE_MAX, UINT_MAX): New macros. 20332 (quotearg_n_options): Abort if N is negative. 20333 Avoid overflow check on hosts where size_t is 64 bits and int 20334 is 32 bits, as overflow is impossible there. 20335 Fix off-by-one typo that caused unnecessary reallocation. 20336 20337 2001-11-29 Paul Eggert <eggert (a] twinsun.com> 20338 20339 Name space cleanup in generated parser. 20340 20341 * doc/bison.texinfo (Bison Parser): Discuss system headers 20342 and their effect on the user name space. 20343 20344 * src/bison.simple: 20345 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX, 20346 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary, 20347 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE). 20348 20349 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing 20350 on user names when possible. 20351 20352 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn. 20353 Simplify test for whather <alloca.h> exists. 20354 20355 (<stdlib.h>): Include if we will use malloc, and if standard C or C++. 20356 20357 (<stdio.h>): Include if YYDEBUG. 20358 20359 (yymemcpy): Renamed from __yy_memcpy. Do not define unless 20360 ! defined (yyoverflow) && ! defined (yymemcpy). 20361 20362 (yymemcpy, yyparse): Rename local variables as needed so that 20363 they all begin with 'yy'. 20364 20365 (yystrlen, yystpcpy): New functions. 20366 20367 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES. 20368 All uses changed. 20369 20370 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy 20371 instead of relying on string.h functions. Use YYSTACK_ALLOC 20372 and YYSTACK_FREE instead of malloc and free. 20373 20374 2001-11-30 Akim Demaille <akim (a] epita.fr> 20375 20376 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions 20377 before their first uses. 20378 (YYBISON, YYPURE): Move to the top of the output. 20379 20380 2001-11-30 Akim Demaille <akim (a] epita.fr> 20381 20382 * tests/reduce.at (Useless Nonterminals): Fix. 20383 20384 2001-11-30 Akim Demaille <akim (a] epita.fr> 20385 20386 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty 20387 if body instead of `;' to pacify GCC's warnings. 20388 20389 2001-11-30 Akim Demaille <akim (a] epita.fr> 20390 20391 Instead of mapping the LHS of unused rules to -1, keep the LHS 20392 valid, but flag the rules as invalid. 20393 20394 * src/gram.h (rule_t): `useful' is a new member. 20395 * src/print.c (print_grammar): Adjust. 20396 * src/derives.c (set_derives): Likewise. 20397 * src/reader.c (packgram, reduce_output): Likewise. 20398 * src/reduce.c (reduce_grammar_tables): Likewise. 20399 * tests/reduce.at (Underivable Rules, Useless Rules): New. 20400 20401 2001-11-30 Akim Demaille <akim (a] epita.fr> 20402 20403 * src/reduce.c (reduce_output): Formatting changes. 20404 * src/print.c (print_results, print_grammar): Likewise. 20405 * tests/regression.at (Rule Line Numbers) 20406 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust. 20407 20408 2001-11-30 Akim Demaille <akim (a] epita.fr> 20409 20410 * src/reduce.c (nonterminals_reduce): Instead of throwing away 20411 useless nonterminals, move them at the end of the symbol arrays. 20412 (reduce_output): Adjust. 20413 * tests/reduce.at (Useless Nonterminals): Adjust. 20414 20415 2001-11-30 Akim Demaille <akim (a] epita.fr> 20416 20417 * src/reduce.c: Various comment/formatting changes. 20418 (nonterminals_reduce): New, extracted from... 20419 (reduce_grammar_tables): here. 20420 (reduce_grammar): Call nonterminals_reduce. 20421 20422 2001-11-29 Paul Eggert <eggert (a] twinsun.com> 20423 20424 * src/bison.simple (YYSTACK_REALLOC): Remove. 20425 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning. 20426 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE): 20427 New macros. 20428 (union yyalloc): New type. 20429 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove 20430 an arbitrary restriction on hosts where size_t is wider than int. 20431 20432 (yyparse): Don't dump core if alloca or malloc fails; instead, report 20433 a parser stack overflow. Allocate just one block of memory for all 20434 three stacks, instead of allocating three blocks; this typically is 20435 faster and reduces fragmentation. 20436 20437 Do not limit the number of items in the stack to a value that fits 20438 in 'int', as this is an arbitrary limit on hosts with 64-bit 20439 size_t and 32-bit int. 20440 20441 2001-11-29 Marc Autret <autret_m (a] epita.fr> 20442 20443 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead 20444 of defining YYERROR_VERBOSE. 20445 [AT_DATA]: $4 is now out of C declarations in the prologue. 20446 20447 2001-11-28 Marc Autret <autret_m (a] epita.fr> 20448 20449 * src/reader.c (parse_dquoted_param): New. 20450 (parse_skel_decl): Use it. 20451 * src/lex.h: Add its prototype. 20452 * src/lex.c (literalchar): Become not static. 20453 20454 2001-11-28 Marc Autret <autret_m (a] epita.fr> 20455 20456 * src/output.h: And put its extern declaration here. 20457 * src/output.c (error_verbose): Define here. 20458 (prepare):
