A new object 53 file format can be supported simply by creating a new BFD back end and 54 adding it to the library. 55 56 BFD is split into two parts: the front end, and the back ends (one 57 for each object file format). 58 * The front end of BFD provides the interface to the user. It manages 59 memory and various canonical data structures. The front end also 60 decides which back end to use and when to call back end routines. 61 62 * The back ends provide BFD its view of the real world. Each back 63 end provides a set of calls which the BFD front end can use to 64 maintain its canonical form. The back ends also may keep around 65 information for their own use, for greater efficiency. 66 67 * Menu: 68 69 * History:: History 70 * How It Works:: How It Works 71 * What BFD Version 2 Can Do:: What BFD Version 2 Can Do 72 73 74 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview 75 76 1.1 History 77 =========== 78 79 One spur behind BFD was the desire, on the part of the GNU 960 team at 80 Intel Oregon, for interoperability of applications on their COFF and 81 b.out file formats. Cygnus was providing GNU support for the team, and 82 was contracted to provide the required functionality. 83 84 The name came from a conversation David Wallace was having with 85 Richard Stallman about the library: RMS said that it would be quite 86 hard--David said "BFD". Stallman was right, but the name stuck. 87 88 At the same time, Ready Systems wanted much the same thing, but for 89 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k 90 coff. 91 92 BFD was first implemented by members of Cygnus Support; Steve 93 Chamberlain (`sac (a] cygnus.com'), John Gilmore (`gnu (a] cygnus.com'), K. 94 Richard Pixley (`rich (a] cygnus.com') and David Henkel-Wallace 95 (`gumby (a] cygnus.com'). 96 97 98 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview 99 100 1.2 How To Use BFD 101 ================== 102 103 To use the library, include `bfd.h' and link with `libbfd.a'. 104 105 BFD provides a common interface to the parts of an object file for a 106 calling application. 107 108 When an application successfully opens a target file (object, 109 archive, or whatever), a pointer to an internal structure is returned. 110 This pointer points to a structure called `bfd', described in `bfd.h'. 111 Our convention is to call this pointer a BFD, and instances of it 112 within code `abfd'. All operations on the target object file are 113 applied as methods to the BFD. The mapping is defined within `bfd.h' 114 in a set of macros, all beginning with `bfd_' to reduce namespace 115 pollution. 116 117 For example, this sequence does what you would probably expect: 118 return the number of sections in an object file attached to a BFD 119 `abfd'. 120 121 #include "bfd.h" 122 123 unsigned int number_of_sections (abfd) 124 bfd *abfd; 125 { 126 return bfd_count_sections (abfd); 127 } 128 129 The abstraction used within BFD is that an object file has: 130 131 * a header, 132 133 * a number of sections containing raw data (*note Sections::), 134 135 * a set of relocations (*note Relocations::), and 136 137 * some symbol information (*note Symbols::). 138 Also, BFDs opened for archives have the additional attribute of an 139 index and contain subordinate BFDs. This approach is fine for a.out and 140 coff, but loses efficiency when applied to formats such as S-records and 141 IEEE-695. 142 143 144 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview 145 146 1.3 What BFD Version 2 Can Do 147 ============================= 148 149 When an object file is opened, BFD subroutines automatically determine 150 the format of the input object file. They then build a descriptor in 151 memory with pointers to routines that will be used to access elements of 152 the object file's data structures. 153 154 As different information from the object files is required, BFD 155 reads from different sections of the file and processes them. For 156 example, a very common operation for the linker is processing symbol 157 tables. Each BFD back end provides a routine for converting between 158 the object file's representation of symbols and an internal canonical 159 format. When the linker asks for the symbol table of an object file, it 160 calls through a memory pointer to the routine from the relevant BFD 161 back end which reads and converts the table into a canonical form. The 162 linker then operates upon the canonical form. When the link is finished 163 and the linker writes the output file's symbol table, another BFD back 164 end routine is called to take the newly created symbol table and 165 convert it into the chosen output format. 166 167 * Menu: 168 169 * BFD information loss:: Information Loss 170 * Canonical format:: The BFD canonical object-file format 171 172 173 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do 174 175 1.3.1 Information Loss 176 ---------------------- 177 178 _Information can be lost during output._ The output formats supported 179 by BFD do not provide identical facilities, and information which can 180 be described in one form has nowhere to go in another format. One 181 example of this is alignment information in `b.out'. There is nowhere 182 in an `a.out' format file to store alignment information on the 183 contained data, so when a file is linked from `b.out' and an `a.out' 184 image is produced, alignment information will not propagate to the 185 output file. (The linker will still use the alignment information 186 internally, so the link is performed correctly). 187 188 Another example is COFF section names. COFF files may contain an 189 unlimited number of sections, each one with a textual section name. If 190 the target of the link is a format which does not have many sections 191 (e.g., `a.out') or has sections without names (e.g., the Oasys format), 192 the link cannot be done simply. You can circumvent this problem by 193 describing the desired input-to-output section mapping with the linker 194 command language. 195 196 _Information can be lost during canonicalization._ The BFD internal 197 canonical form of the external formats is not exhaustive; there are 198 structures in input formats for which there is no direct representation 199 internally. This means that the BFD back ends cannot maintain all 200 possible data richness through the transformation between external to 201 internal and back to external formats. 202 203 This limitation is only a problem when an application reads one 204 format and writes another. Each BFD back end is responsible for 205 maintaining as much data as possible, and the internal BFD canonical 206 form has structures which are opaque to the BFD core, and exported only 207 to the back ends. When a file is read in one format, the canonical form 208 is generated for BFD and the application. At the same time, the back 209 end saves away any information which may otherwise be lost. If the data 210 is then written back in the same format, the back end routine will be 211 able to use the canonical form provided by the BFD core as well as the 212 information it prepared earlier. Since there is a great deal of 213 commonality between back ends, there is no information lost when 214 linking or copying big endian COFF to little endian COFF, or `a.out' to 215 `b.out'. When a mixture of formats is linked, the information is only 216 lost from the files whose format differs from the destination. 217 218 219 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do 220 221 1.3.2 The BFD canonical object-file format 222 ------------------------------------------ 223 224 The greatest potential for loss of information occurs when there is the 225 least overlap between the information provided by the source format, 226 that stored by the canonical format, and that needed by the destination 227 format. A brief description of the canonical form may help you 228 understand which kinds of data you can count on preserving across 229 conversions. 230 231 _files_ 232 Information stored on a per-file basis includes target machine 233 architecture, particular implementation format type, a demand 234 pageable bit, and a write protected bit. Information like Unix 235 magic numbers is not stored here--only the magic numbers' meaning, 236 so a `ZMAGIC' file would have both the demand pageable bit and the 237 write protected text bit set. The byte order of the target is 238 stored on a per-file basis, so that big- and little-endian object 239 files may be used with one another. 240 241 _sections_ 242 Each section in the input file contains the name of the section, 243 the section's original address in the object file, size and 244 alignment information, various flags, and pointers into other BFD 245 data structures. 246 247 _symbols_ 248 Each symbol contains a pointer to the information for the object 249 file which originally defined it, its name, its value, and various 250 flag bits. When a BFD back end reads in a symbol table, it 251 relocates all symbols to make them relative to the base of the 252 section where they were defined. Doing this ensures that each 253 symbol points to its containing section. Each symbol also has a 254 varying amount of hidden private data for the BFD back end. Since 255 the symbol points to the original file, the private data format 256 for that symbol is accessible. `ld' can operate on a collection 257 of symbols of wildly different formats without problems. 258 259 Normal global and simple local symbols are maintained on output, 260 so an output file (no matter its format) will retain symbols 261 pointing to functions and to global, static, and common variables. 262 Some symbol information is not worth retaining; in `a.out', type 263 information is stored in the symbol table as long symbol names. 264 This information would be useless to most COFF debuggers; the 265 linker has command line switches to allow users to throw it away. 266 267 There is one word of type information within the symbol, so if the 268 format supports symbol type information within symbols (for 269 example, COFF, IEEE, Oasys) and the type is simple enough to fit 270 within one word (nearly everything but aggregates), the 271 information will be preserved. 272 273 _relocation level_ 274 Each canonical BFD relocation record contains a pointer to the 275 symbol to relocate to, the offset of the data to relocate, the 276 section the data is in, and a pointer to a relocation type 277 descriptor. Relocation is performed by passing messages through 278 the relocation type descriptor and the symbol pointer. Therefore, 279 relocations can be performed on output data using a relocation 280 method that is only available in one of the input formats. For 281 instance, Oasys provides a byte relocation format. A relocation 282 record requesting this relocation type would point indirectly to a 283 routine to perform this, so the relocation may be performed on a 284 byte being written to a 68k COFF file, even though 68k COFF has no 285 such relocation type. 286 287 _line numbers_ 288 Object formats can contain, for debugging purposes, some form of 289 mapping between symbols, source line numbers, and addresses in the 290 output file. These addresses have to be relocated along with the 291 symbol information. Each symbol with an associated list of line 292 number records points to the first record of the list. The head 293 of a line number list consists of a pointer to the symbol, which 294 allows finding out the address of the function whose line number 295 is being described. The rest of the list is made up of pairs: 296 offsets into the section and line numbers. Any format which can 297 simply derive this information can pass it successfully between 298 formats (COFF, IEEE and Oasys). 299 300 301 File: bfd.info, Node: BFD front end, Next: BFD back ends, Prev: Overview, Up: Top 302 303 2 BFD Front End 304 *************** 305 306 2.1 `typedef bfd' 307 ================= 308 309 A BFD has type `bfd'; objects of this type are the cornerstone of any 310 application using BFD.

If that returns `bfd_error_system_call', then 596 check `errno'. 597 598 The easiest way to report a BFD error to the user is to use 599 `bfd_perror'. 600 601 2.2.1 Type `bfd_error_type' 602 --------------------------- 603 604 The values returned by `bfd_get_error' are defined by the enumerated 605 type `bfd_error_type'. 606 607 608 typedef enum bfd_error 609 { 610 bfd_error_no_error = 0, 611 bfd_error_system_call, 612 bfd_error_invalid_target, 613 bfd_error_wrong_format, 614 bfd_error_wrong_object_format, 615 bfd_error_invalid_operation, 616 bfd_error_no_memory, 617 bfd_error_no_symbols, 618 bfd_error_no_armap, 619 bfd_error_no_more_archived_files, 620 bfd_error_malformed_archive, 621 bfd_error_file_not_recognized, 622 bfd_error_file_ambiguously_recognized, 623 bfd_error_no_contents, 624 bfd_error_nonrepresentable_section, 625 bfd_error_no_debug_section, 626 bfd_error_bad_value, 627 bfd_error_file_truncated, 628 bfd_error_file_too_big, 629 bfd_error_on_input, 630 bfd_error_invalid_error_code 631 } 632 bfd_error_type; 633 634 2.2.1.1 `bfd_get_error' 635 ....................... 636 637 *Synopsis* 638 bfd_error_type bfd_get_error (void); 639 *Description* 640 Return the current BFD error condition. 641 642 2.2.1.2 `bfd_set_error' 643 ....................... 644 645 *Synopsis* 646 void bfd_set_error (bfd_error_type error_tag, ...); 647 *Description* 648 Set the BFD error condition to be ERROR_TAG.

If MESSAGE is non-NULL and non-empty, the error 670 string printed is preceded by MESSAGE, a colon, and a space. It is 671 followed by a newline. 672 673 2.2.2 BFD error handler 674 ----------------------- 675 676 Some BFD functions want to print messages describing the problem. They 677 call a BFD error handler function. This function may be overridden by 678 the program. 679 680 The BFD error handler acts like printf. 681 682 683 typedef void (*bfd_error_handler_type) (const char *, ...); 684 685 2.2.2.1 `bfd_set_error_handler' 686 ............................... 687 688 *Synopsis* 689 bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type); 690 *Description* 691 Set the BFD error handler function.

E.g., an attempt 768 was made to set the `D_PAGED' bit on a BFD format which does not 769 support demand paging. 770 771 2.3.1.5 `bfd_get_arch_size' 772 ........................... 773 774 *Synopsis* 775 int bfd_get_arch_size (bfd *abfd); 776 *Description* 777 Returns the architecture address size, in bits, as determined by the 778 object file's format.

Some architectures implicitly sign extend address values when 792 they are converted to types larger than the size of an address. For 793 instance, bfd_get_start_address() will return an address sign extended 794 to fill a bfd_vma when this is the case. 795 796 *Returns* 797 Returns `1' if the target architecture is known to sign extend 798 addresses, `0' if the target architecture is known to not sign extend 799 addresses, and `-1' otherwise. 800 801 2.3.1.7 `bfd_set_start_address' 802 ............................... 803 804 *Synopsis* 805 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma); 806 *Description* 807 Make VMA the entry point of output BFD ABFD. 808 809 *Returns* 810 Returns `TRUE' on success, `FALSE' otherwise. 811 812 2.3.1.8 `bfd_get_gp_size' 813 ......................... 814 815 *Synopsis* 816 unsigned int bfd_get_gp_size (bfd *abfd); 817 *Description* 818 Return the maximum size of objects to be optimized using the GP 819 register under MIPS ECOFF.

(Though without as many bells and 840 whistles as `strtoul'.) The expression is assumed to be unsigned 841 (i.e., positive). If given a BASE, it is used as the base for 842 conversion. A base of 0 causes the function to interpret the string in 843 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading 844 zero is found, otherwise in decimal. 845 846 If the value would overflow, the maximum `bfd_vma' value is returned. 847 848 2.3.1.11 `bfd_copy_private_header_data' 849 ....................................... 850 851 *Synopsis* 852 bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd); 853 *Description* 854 Copy private BFD header information from the BFD IBFD to the the BFD 855 OBFD.

As as 1177 example of where we might do this, some object formats use string 1178 tables for which the first `sizeof (long)' bytes of the table contain 1179 the size of the table itself, including the size bytes. If an 1180 application tries to read what it thinks is one of these string tables, 1181 without some way to validate the size, and for some reason the size is 1182 wrong (byte swapping error, wrong location for the string table, etc.), 1183 the only clue is likely to be a read error when it tries to read the 1184 table, or a "virtual memory exhausted" error when it tries to allocate 1185 15 bazillon bytes of space for the 15 bazillon byte table it is about 1186 to read. This function at least allows us to answer the question, "is 1187 the size reasonable?". 1188 1189 2.3.1.28 `bfd_mmap' 1190 ................... 1191 1192 *Synopsis* 1193 void *bfd_mmap (bfd *abfd, void *addr, bfd_size_type len, 1194 int prot, int flags, file_ptr offset); 1195 *Description* 1196 Return mmap()ed region of the file, if possible and implemented. 1197 1198 * Menu: 1199 1200 * Memory Usage:: 1201 * Initialization:: 1202 * Sections:: 1203 * Symbols:: 1204 * Archives:: 1205 * Formats:: 1206 * Relocations:: 1207 * Core Files:: 1208 * Targets:: 1209 * Architectures:: 1210 * Opening and Closing:: 1211 * Internal:: 1212 * File Caching:: 1213 * Linker Functions:: 1214 * Hash Tables:: 1215 1216 1217 File: bfd.info, Node: Memory Usage, Next: Initialization, Prev: BFD front end, Up: BFD front end 1218 1219 2.4 Memory Usage 1220 ================ 1221 1222 BFD keeps all of its internal structures in obstacks. There is one 1223 obstack per open BFD file, into which the current state is stored. When 1224 a BFD is closed, the obstack is deleted, and so everything which has 1225 been allocated by BFD for the closing file is thrown away. 1226 1227 BFD does not free anything created by an application, but pointers 1228 into `bfd' structures become invalid on a `bfd_close'; for example, 1229 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is 1230 still around, since it has been allocated by the application, but the 1231 data that it pointed to are lost. 1232 1233 The general rule is to not close a BFD until all operations dependent 1234 upon data from the BFD have been completed, or all the data from within 1235 the file has been copied. To help with the management of memory, there 1236 is a function (`bfd_alloc_size') which returns the number of bytes in 1237 obstacks associated with the supplied BFD. This could be used to select 1238 the greediest open BFD, close it to reclaim the memory, perform some 1239 operation and reopen the BFD again, to get a fresh copy of the data 1240 structures. 1241 1242 1243 File: bfd.info, Node: Initialization, Next: Sections, Prev: Memory Usage, Up: BFD front end 1244 1245 2.5 Initialization 1246 ================== 1247 1248 2.5.1 Initialization functions 1249 ------------------------------ 1250 1251 These are the functions that handle initializing a BFD. 1252 1253 2.5.1.1 `bfd_init' 1254 .................. 1255 1256 *Synopsis* 1257 void bfd_init (void); 1258 *Description* 1259 This routine must be called before any other BFD function to initialize 1260 magical internal data structures. 1261 1262 1263 File: bfd.info, Node: Sections, Next: Symbols, Prev: Initialization, Up: BFD front end 1264 1265 2.6 Sections 1266 ============ 1267 1268 The raw data contained within a BFD is maintained through the section 1269 abstraction. A single BFD may have any number of sections. It keeps 1270 hold of them by pointing to the first; each one points to the next in 1271 the list. 1272 1273 Sections are supported in BFD in `section.c'. 1274 1275 * Menu: 1276 1277 * Section Input:: 1278 * Section Output:: 1279 * typedef asection:: 1280 * section prototypes:: 1281 1282 1283 File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections 1284 1285 2.6.1 Section input 1286 ------------------- 1287 1288 When a BFD is opened for reading, the section structures are created 1289 and attached to the BFD. 1290 1291 Each section has a name which describes the section in the outside 1292 world--for example, `a.out' would contain at least three sections, 1293 called `.text', `.data' and `.bss'. 1294 1295 Names need not be unique; for example a COFF file may have several 1296 sections named `.data'. 1297 1298 Sometimes a BFD will contain more than the "natural" number of 1299 sections. A back end may attach other sections containing constructor 1300 data, or an application may add a section (using `bfd_make_section') to 1301 the sections attached to an already open BFD. For example, the linker 1302 creates an extra section `COMMON' for each input file's BFD to hold 1303 information about common storage. 1304 1305 The raw data is not necessarily read in when the section descriptor 1306 is created. Some targets may leave the data in place until a 1307 `bfd_get_section_contents' call is made. Other back ends may read in 1308 all the data at once. For example, an S-record file has to be read 1309 once to determine the size of the data. An IEEE-695 file doesn't 1310 contain raw data in sections, but data and relocation expressions 1311 intermixed, so the data area has to be parsed to get out the data and 1312 relocations. 1313 1314 1315 File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections 1316 1317 2.6.2 Section output 1318 -------------------- 1319 1320 To write a new object style BFD, the various sections to be written 1321 have to be created. They are attached to the BFD in the same way as 1322 input sections; data is written to the sections using 1323 `bfd_set_section_contents'. 1324 1325 Any program that creates or combines sections (e.g., the assembler 1326 and linker) must use the `asection' fields `output_section' and 1327 `output_offset' to indicate the file sections to which each section 1328 must be written. (If the section is being created from scratch, 1329 `output_section' should probably point to the section itself and 1330 `output_offset' should probably be zero.) 1331 1332 The data to be written comes from input sections attached (via 1333 `output_section' pointers) to the output sections. The output section 1334 structure can be considered a filter for the input section: the output 1335 section determines the vma of the output data and the name, but the 1336 input section determines the offset into the output section of the data 1337 to be written. 1338 1339 E.g., to create a section "O", starting at 0x100, 0x123 long, 1340 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and 1341 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would 1342 look like: 1343 1344 section name "A" 1345 output_offset 0x00 1346 size 0x20 1347 output_section -----------> section name "O" 1348 | vma 0x100 1349 section name "B" | size 0x123 1350 output_offset 0x20 | 1351 size 0x103 | 1352 output_section --------| 1353 1354 2.6.3 Link orders 1355 ----------------- 1356 1357 The data within a section is stored in a "link_order". These are much 1358 like the fixups in `gas'. The link_order abstraction allows a section 1359 to grow and shrink within itself. 1360 1361 A link_order knows how big it is, and which is the next link_order 1362 and where the raw data for it is; it also points to a list of 1363 relocations which apply to it. 1364 1365 The link_order is used by the linker to perform relaxing on final 1366 code. The compiler creates code which is as big as necessary to make 1367 it work without relaxing, and the user can select whether to relax. 1368 Sometimes relaxing takes a lot of time. The linker runs around the 1369 relocations to see if any are attached to data which can be shrunk, if 1370 so it does it on a link_order by link_order basis. 1371 1372 1373 File: bfd.info, Node: typedef asection, Next: section prototypes, Prev: Section Output, Up: Sections 1374 1375 2.6.4 typedef asection 1376 ---------------------- 1377 1378 Here is the section structure: 1379 1380 1381 typedef struct bfd_section 1382 { 1383 /* The name of the section; the name isn't a copy, the pointer is 1384 the same as that passed to bfd_make_section. */ 1385 const char *name; 1386 1387 /* A unique sequence number. */ 1388 int id; 1389 1390 /* Which section in the bfd; 0..n-1 as sections are created in a bfd. */ 1391 int index; 1392 1393 /* The next section in the list belonging to the BFD, or NULL. */ 1394 struct bfd_section *next; 1395 1396 /* The previous section in the list belonging to the BFD, or NULL. */ 1397 struct bfd_section *prev; 1398 1399 /* The field flags contains attributes of the section.

BFD passes information to 2233 applications though the `asymbol' structure. When the application 2234 requests the symbol table, BFD reads the table in the native form and 2235 translates parts of it into the internal format. To maintain more than 2236 the information passed to applications, some targets keep some 2237 information "behind the scenes" in a structure only the particular back 2238 end knows about. For example, the coff back end keeps the original 2239 symbol table structure as well as the canonical structure when a BFD is 2240 read in. On output, the coff back end can reconstruct the output symbol 2241 table so that no information is lost, even information unique to coff 2242 which BFD doesn't know or understand. If a coff symbol table were read, 2243 but were written through an a.out back end, all the coff specific 2244 information would be lost. The symbol table of a BFD is not necessarily 2245 read in until a canonicalize request is made. Then the BFD back end 2246 fills in a table provided by the application with pointers to the 2247 canonical information. To output symbols, the application provides BFD 2248 with a table of pointers to pointers to `asymbol's. This allows 2249 applications like the linker to output a symbol as it was read, since 2250 the "behind the scenes" information will be still available. 2251 2252 * Menu: 2253 2254 * Reading Symbols:: 2255 * Writing Symbols:: 2256 * Mini Symbols:: 2257 * typedef asymbol:: 2258 * symbol handling functions:: 2259 2260 2261 File: bfd.info, Node: Reading Symbols, Next: Writing Symbols, Prev: Symbols, Up: Symbols 2262 2263 2.7.1 Reading symbols 2264 --------------------- 2265 2266 There are two stages to reading a symbol table from a BFD: allocating 2267 storage, and the actual reading process. This is an excerpt from an 2268 application which reads the symbol table: 2269 2270 long storage_needed; 2271 asymbol **symbol_table; 2272 long number_of_symbols; 2273 long i; 2274 2275 storage_needed = bfd_get_symtab_upper_bound (abfd); 2276 2277 if (storage_needed < 0) 2278 FAIL 2279 2280 if (storage_needed == 0) 2281 return; 2282 2283 symbol_table = xmalloc (storage_needed); 2284 ... 2285 number_of_symbols = 2286 bfd_canonicalize_symtab (abfd, symbol_table); 2287 2288 if (number_of_symbols < 0) 2289 FAIL 2290 2291 for (i = 0; i < number_of_symbols; i++) 2292 process_symbol (symbol_table[i]); 2293 2294 All storage for the symbols themselves is in an objalloc connected 2295 to the BFD; it is freed when the BFD is closed. 2296 2297 2298 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols 2299 2300 2.7.2 Writing symbols 2301 --------------------- 2302 2303 Writing of a symbol table is automatic when a BFD open for writing is 2304 closed. The application attaches a vector of pointers to pointers to 2305 symbols to the BFD being written, and fills in the symbol count. The 2306 close and cleanup code reads through the table provided and performs 2307 all the necessary operations. The BFD output code must always be 2308 provided with an "owned" symbol: one which has come from another BFD, 2309 or one which has been created using `bfd_make_empty_symbol'. Here is an 2310 example showing the creation of a symbol table with only one element: 2311 2312 #include "bfd.h" 2313 int main (void) 2314 { 2315 bfd *abfd; 2316 asymbol *ptrs[2]; 2317 asymbol *new; 2318 2319 abfd = bfd_openw ("foo","a.out-sunos-big"); 2320 bfd_set_format (abfd, bfd_object); 2321 new = bfd_make_empty_symbol (abfd); 2322 new->name = "dummy_symbol"; 2323 new->section = bfd_make_section_old_way (abfd, ".text"); 2324 new->flags = BSF_GLOBAL; 2325 new->value = 0x12345; 2326 2327 ptrs[0] = new; 2328 ptrs[1] = 0; 2329 2330 bfd_set_symtab (abfd, ptrs, 1); 2331 bfd_close (abfd); 2332 return 0; 2333 } 2334 2335 ./makesym 2336 nm foo 2337 00012345 A dummy_symbol 2338 2339 Many formats cannot represent arbitrary symbol information; for 2340 instance, the `a.out' object format does not allow an arbitrary number 2341 of sections. A symbol pointing to a section which is not one of 2342 `.text', `.data' or `.bss' cannot be described. 2343 2344 2345 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols 2346 2347 2.7.3 Mini Symbols 2348 ------------------ 2349 2350 Mini symbols provide read-only access to the symbol table. They use 2351 less memory space, but require more time to access. They can be useful 2352 for tools like nm or objdump, which may have to handle symbol tables of 2353 extremely large executables. 2354 2355 The `bfd_read_minisymbols' function will read the symbols into 2356 memory in an internal form. It will return a `void *' pointer to a 2357 block of memory, a symbol count, and the size of each symbol. The 2358 pointer is allocated using `malloc', and should be freed by the caller 2359 when it is no longer needed. 2360 2361 The function `bfd_minisymbol_to_symbol' will take a pointer to a 2362 minisymbol, and a pointer to a structure returned by 2363 `bfd_make_empty_symbol', and return a `asymbol' structure. The return 2364 value may or may not be the same as the value from 2365 `bfd_make_empty_symbol' which was passed in. 2366 2367 2368 File: bfd.info, Node: typedef asymbol, Next: symbol handling functions, Prev: Mini Symbols, Up: Symbols 2369 2370 2.7.4 typedef asymbol 2371 --------------------- 2372 2373 An `asymbol' has the form: 2374 2375 2376 typedef struct bfd_symbol 2377 { 2378 /* A pointer to the BFD which owns the symbol.

It has a symbol table, 2685 although there's not much a user program will do with it. 2686 2687 The big difference between an archive BFD and an ordinary BFD is 2688 that the archive doesn't have sections. Instead it has a chain of BFDs 2689 that are considered its contents. These BFDs can be manipulated like 2690 any other. The BFDs contained in an archive opened for reading will 2691 all be opened for reading. You may put either input or output BFDs 2692 into an archive opened for output; they will be handled correctly when 2693 the archive is closed. 2694 2695 Use `bfd_openr_next_archived_file' to step through the contents of 2696 an archive opened for input. You don't have to read the entire archive 2697 if you don't want to! Read it until you find what you want. 2698 2699 Archive contents of output BFDs are chained through the `next' 2700 pointer in a BFD. The first one is findable through the `archive_head' 2701 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A 2702 given BFD may be in only one open output archive at a time. 2703 2704 As expected, the BFD archive code is more general than the archive 2705 code of any given environment. BFD archives may contain files of 2706 different formats (e.g., a.out and coff) and even different 2707 architectures. You may even place archives recursively into archives! 2708 2709 This can cause unexpected confusion, since some archive formats are 2710 more expressive than others. For instance, Intel COFF archives can 2711 preserve long filenames; SunOS a.out archives cannot. If you move a 2712 file from the first to the second format and back again, the filename 2713 may be truncated. Likewise, different a.out environments have different 2714 conventions as to how they truncate filenames, whether they preserve 2715 directory names in filenames, etc. When interoperating with native 2716 tools, be sure your files are homogeneous. 2717 2718 Beware: most of these formats do not react well to the presence of 2719 spaces in filenames. We do the best we can, but can't always handle 2720 this case due to restrictions in the format of archives. Many Unix 2721 utilities are braindead in regards to spaces and such in filenames 2722 anyway, so this shouldn't be much of a restriction. 2723 2724 Archives are supported in BFD in `archive.c'. 2725 2726 2.8.1 Archive functions 2727 ----------------------- 2728 2729 2.8.1.1 `bfd_get_next_mapent' 2730 ............................. 2731 2732 *Synopsis* 2733 symindex bfd_get_next_mapent 2734 (bfd *abfd, symindex previous, carsym **sym); 2735 *Description* 2736 Step through archive ABFD's symbol table (if it has one).

A common routine 2864 `bfd_perform_relocation' acts upon the canonical form to do the fixup. 2865 2866 Relocations are maintained on a per section basis, while symbols are 2867 maintained on a per BFD basis. 2868 2869 All that a back end has to do to fit the BFD interface is to create 2870 a `struct reloc_cache_entry' for each relocation in a particular 2871 section, and fill in the right bits of the structures. 2872 2873 * Menu: 2874 2875 * typedef arelent:: 2876 * howto manager:: 2877 2878 2879 File: bfd.info, Node: typedef arelent, Next: howto manager, Prev: Relocations, Up: Relocations 2880 2881 2.10.1 typedef arelent 2882 ---------------------- 2883 2884 This is the structure of a relocation entry: 2885 2886 2887 typedef enum bfd_reloc_status 2888 { 2889 /* No errors detected. */ 2890 bfd_reloc_ok, 2891 2892 /* The relocation was performed, but there was an overflow. */ 2893 bfd_reloc_overflow, 2894 2895 /* The address to relocate was not within the section supplied. */ 2896 bfd_reloc_outofrange, 2897 2898 /* Used by special functions. */ 2899 bfd_reloc_continue, 2900 2901 /* Unsupported relocation size requested. */ 2902 bfd_reloc_notsupported, 2903 2904 /* Unused. */ 2905 bfd_reloc_other, 2906 2907 /* The symbol to relocate against was undefined. */ 2908 bfd_reloc_undefined, 2909 2910 /* The relocation was performed, but may not be ok - presently 2911 generated only when linking i960 coff files with i960 b.out 2912 symbols.

It is the pointer into the 2941 table returned by the back end's `canonicalize_symtab' action. *Note 2942 Symbols::. The symbol is referenced through a pointer to a pointer so 2943 that tools like the linker can fix up all the symbols of the same name 2944 by modifying only one pointer. The relocation routine looks in the 2945 symbol and uses the base of the section the symbol is attached to and 2946 the value of the symbol as the initial relocation offset. If the symbol 2947 pointer is zero, then the section provided is looked up. 2948 2949 * `address' 2950 The `address' field gives the offset in bytes from the base of the 2951 section data which owns the relocation record to the first byte of 2952 relocatable information. The actual data relocated will be relative to 2953 this point; for example, a relocation type which modifies the bottom 2954 two bytes of a four byte word would not touch the first byte pointed to 2955 in a big endian world. 2956 2957 * `addend' 2958 The `addend' is a value provided by the back end to be added (!) to 2959 the relocation offset. Its interpretation is dependent upon the howto. 2960 For example, on the 68k the code: 2961 2962 char foo[]; 2963 main() 2964 { 2965 return foo[0x12345678]; 2966 } 2967 2968 Could be compiled into: 2969 2970 linkw fp,#-4 2971 moveb @#12345678,d0 2972 extbl d0 2973 unlk fp 2974 rts 2975 2976 This could create a reloc pointing to `foo', but leave the offset in 2977 the data, something like: 2978 2979 RELOCATION RECORDS FOR [.text]: 2980 offset type value 2981 00000006 32 _foo 2982 2983 00000000 4e56 fffc ; linkw fp,#-4 2984 00000004 1039 1234 5678 ; moveb @#12345678,d0 2985 0000000a 49c0 ; extbl d0 2986 0000000c 4e5e ; unlk fp 2987 0000000e 4e75 ; rts 2988 2989 Using coff and an 88k, some instructions don't have enough space in 2990 them to represent the full address range, and pointers have to be 2991 loaded in two parts. So you'd get something like: 2992 2993 or.u r13,r0,hi16(_foo+0x12345678) 2994 ld.b r2,r13,lo16(_foo+0x12345678) 2995 jmp r1 2996 2997 This should create two relocs, both pointing to `_foo', and with 2998 0x12340000 in their addend field. The data would consist of: 2999 3000 RELOCATION RECORDS FOR [.text]: 3001 offset type value 3002 00000002 HVRT16 _foo+0x12340000 3003 00000006 LVRT16 _foo+0x12340000 3004 3005 00000000 5da05678 ; or.u r13,r0,0x5678 3006 00000004 1c4d5678 ; ld.b r2,r13,0x5678 3007 00000008 f400c001 ; jmp r1 3008 3009 The relocation routine digs out the value from the data, adds it to 3010 the addend to get the original offset, and then adds the value of 3011 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope 3012 with carry from bit 15 to bit 16. 3013 3014 One further example is the sparc and the a.out format. The sparc has 3015 a similar problem to the 88k, in that some instructions don't have room 3016 for an entire offset, but on the sparc the parts are created in odd 3017 sized lumps. The designers of the a.out format chose to not use the 3018 data within the section for storing part of the offset; all the offset 3019 is kept within the reloc. Anything in the data should be ignored. 3020 3021 save %sp,-112,%sp 3022 sethi %hi(_foo+0x12345678),%g2 3023 ldsb [%g2+%lo(_foo+0x12345678)],%i0 3024 ret 3025 restore 3026 3027 Both relocs contain a pointer to `foo', and the offsets contain junk. 3028 3029 RELOCATION RECORDS FOR [.text]: 3030 offset type value 3031 00000004 HI22 _foo+0x12345678 3032 00000008 LO10 _foo+0x12345678 3033 3034 00000000 9de3bf90 ; save %sp,-112,%sp 3035 00000004 05000000 ; sethi %hi(_foo+0),%g2 3036 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0 3037 0000000c 81c7e008 ; ret 3038 00000010 81e80000 ; restore 3039 3040 * `howto' 3041 The `howto' field can be imagined as a relocation instruction. It is 3042 a pointer to a structure which contains information on what to do with 3043 all of the other information in the reloc record and data section. A 3044 back end would normally have a relocation instruction set and turn 3045 relocations into pointers to the correct structure on input - but it 3046 would be possible to create each howto field on demand. 3047 3048 2.10.1.1 `enum complain_overflow' 3049 ................................. 3050 3051 Indicates what sort of overflow checking should be done when performing 3052 a relocation. 3053 3054 3055 enum complain_overflow 3056 { 3057 /* Do not complain on overflow. */ 3058 complain_overflow_dont, 3059 3060 /* Complain if the value overflows when considered as a signed 3061 number one bit larger than the field. ie.

Some native formats (e.g., basic a.out and basic coff) have no 3260 way of specifying an addend in the relocation type, so the addend has 3261 to go in the output data. This is no big deal since in these formats 3262 the output data slot will always be big enough for the addend. Complex 3263 reloc types with addends were invented to solve just this problem.

Some of these treat the symbol or 3520 "addend" in some special way. For GPDISP_HI16 ("gpdisp") 3521 relocations, the symbol is ignored when writing; when reading, it 3522 will be the absolute section symbol.

The addend is ignored when writing, but is filled 3547 in with the file's GP value on reading, for convenience, as with 3548 the GPDISP_LO16 reloc. 3549 3550 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and 3551 GPDISP_LO16.

All the back end provides to the root part of BFD is a 5847 structure containing pointers to functions which perform certain low 5848 level operations on files. BFD translates the applications's requests 5849 through a pointer into calls to the back end routines. 5850 5851 When a file is opened with `bfd_openr', its format and target are 5852 unknown. BFD uses various mechanisms to determine how to interpret the 5853 file. The operations performed are: 5854 5855 * Create a BFD by calling the internal routine `_bfd_new_bfd', then 5856 call `bfd_find_target' with the target string supplied to 5857 `bfd_openr' and the new BFD pointer. 5858 5859 * If a null target string was provided to `bfd_find_target', look up 5860 the environment variable `GNUTARGET' and use that as the target 5861 string. 5862 5863 * If the target string is still `NULL', or the target string is 5864 `default', then use the first item in the target vector as the 5865 target type, and set `target_defaulted' in the BFD to cause 5866 `bfd_check_format' to loop through all the targets. *Note 5867 bfd_target::. *Note Formats::. 5868 5869 * Otherwise, inspect the elements in the target vector one by one, 5870 until a match on target name is found. When found, use it. 5871 5872 * Otherwise return the error `bfd_error_invalid_target' to 5873 `bfd_openr'. 5874 5875 * `bfd_openr' attempts to open the file using `bfd_open_file', and 5876 returns the BFD. 5877 Once the BFD has been opened and the target selected, the file 5878 format may be determined. This is done by calling `bfd_check_format' on 5879 the BFD with a suggested format. If `target_defaulted' has been set, 5880 each possible target type is tried to see if it recognizes the 5881 specified format. `bfd_check_format' returns `TRUE' when the caller 5882 guesses right. 5883 5884 * Menu: 5885 5886 * bfd_target:: 5887 5888 5889 File: bfd.info, Node: bfd_target, Prev: Targets, Up: Targets 5890 5891 2.12.1 bfd_target 5892 ----------------- 5893 5894 *Description* 5895 This structure contains everything that BFD knows about a target. It 5896 includes things like its byte order, name, and which routines to call 5897 to do various operations. 5898 5899 Every BFD points to a target structure with its `xvec' member. 5900 5901 The macros below are used to dispatch to functions through the 5902 `bfd_target' vector. They are used in a number of macros further down 5903 in `bfd.h', and are also used when calling various routines by hand 5904 inside the BFD implementation. The ARGLIST argument must be 5905 parenthesized; it contains all the arguments to the called function. 5906 5907 They make the documentation (more) unpleasant to read, so if someone 5908 wants to fix this and not break the above, please do. 5909 #define BFD_SEND(bfd, message, arglist) \ 5910 ((*((bfd)->xvec->message)) arglist) 5911 5912 #ifdef DEBUG_BFD_SEND 5913 #undef BFD_SEND 5914 #define BFD_SEND(bfd, message, arglist) \ 5915 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ 5916 ((*((bfd)->xvec->message)) arglist) : \ 5917 (bfd_assert (__FILE__,__LINE__), NULL)) 5918 #endif 5919 For operations which index on the BFD format: 5920 #define BFD_SEND_FMT(bfd, message, arglist) \ 5921 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) 5922 5923 #ifdef DEBUG_BFD_SEND 5924 #undef BFD_SEND_FMT 5925 #define BFD_SEND_FMT(bfd, message, arglist) \ 5926 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ 5927 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \ 5928 (bfd_assert (__FILE__,__LINE__), NULL)) 5929 #endif 5930 This is the structure which defines the type of BFD this is. The 5931 `xvec' member of the struct `bfd' itself points here. Each module that 5932 implements access to a different target under BFD, defines one of these. 5933 5934 FIXME, these names should be rationalised with the names of the 5935 entry points which call them. Too bad we can't have one macro to define 5936 them both! 5937 enum bfd_flavour 5938 { 5939 bfd_target_unknown_flavour, 5940 bfd_target_aout_flavour, 5941 bfd_target_coff_flavour, 5942 bfd_target_ecoff_flavour, 5943 bfd_target_xcoff_flavour, 5944 bfd_target_elf_flavour, 5945 bfd_target_ieee_flavour, 5946 bfd_target_nlm_flavour, 5947 bfd_target_oasys_flavour, 5948 bfd_target_tekhex_flavour, 5949 bfd_target_srec_flavour, 5950 bfd_target_verilog_flavour, 5951 bfd_target_ihex_flavour, 5952 bfd_target_som_flavour, 5953 bfd_target_os9k_flavour, 5954 bfd_target_versados_flavour, 5955 bfd_target_msdos_flavour, 5956 bfd_target_ovax_flavour, 5957 bfd_target_evax_flavour, 5958 bfd_target_mmo_flavour, 5959 bfd_target_mach_o_flavour, 5960 bfd_target_pef_flavour, 5961 bfd_target_pef_xlib_flavour, 5962 bfd_target_sym_flavour 5963 }; 5964 5965 enum bfd_endian { BFD_ENDIAN_BIG, BFD_ENDIAN_LITTLE, BFD_ENDIAN_UNKNOWN }; 5966 5967 /* Forward declaration. */ 5968 typedef struct bfd_link_info _bfd_link_info; 5969 5970 typedef struct bfd_target 5971 { 5972 /* Identifies the kind of target, e.g., SunOS4, Ultrix, etc. */ 5973 char *name; 5974 5975 /* The "flavour" of a back end is a general indication about 5976 the contents of a file. */ 5977 enum bfd_flavour flavour; 5978 5979 /* The order of bytes within the data area of a file. */ 5980 enum bfd_endian byteorder; 5981 5982 /* The order of bytes within the header parts of a file. */ 5983 enum bfd_endian header_byteorder; 5984 5985 /* A mask of all the flags which an executable may have set - 5986 from the set `BFD_NO_FLAGS', `HAS_RELOC', ...`D_PAGED'. */ 5987 flagword object_flags; 5988 5989 /* A mask of all the flags which a section may have set - from 5990 the set `SEC_NO_FLAGS', `SEC_ALLOC', ...`SET_NEVER_LOAD'. */ 5991 flagword section_flags; 5992 5993 /* The character normally found at the front of a symbol. 5994 (if any), perhaps `_'. */ 5995 char symbol_leading_char; 5996 5997 /* The pad character for file names within an archive header. */ 5998 char ar_pad_char; 5999 6000 /* The maximum number of characters in an archive header. */ 6001 unsigned short ar_max_namelen; 6002 6003 /* Entries for byte swapping for data.

The set of default architectures is selected by the macro 6423 `SELECT_ARCHITECTURES'. This is normally set up in the 6424 `config/TARGET.mt' file of your choice. If the name is not defined, 6425 then all the architectures supported are included. 6426 6427 When BFD starts up, all the architectures are called with an 6428 initialize method. It is up to the architecture back end to insert as 6429 many items into the list of architectures as it wants to; generally 6430 this would be one for each machine and one for the default case (an 6431 item with a machine field of 0). 6432 6433 BFD's idea of an architecture is implemented in `archures.c'. 6434 6435 2.13.1 bfd_architecture 6436 ----------------------- 6437 6438 *Description* 6439 This enum gives the object file's CPU architecture, in a global 6440 sense--i.e., what processor family does it belong to? Another field 6441 indicates which processor within the family is in use. The machine 6442 gives a number which distinguishes different versions of the 6443 architecture, containing, for example, 2 and 3 for Intel i960 KA and 6444 i960 KB, and 68020 and 68030 for Motorola

It 7076 opens a BFD on a file already described by the FD supplied. 7077 7078 When the file is later `bfd_close'd, the file descriptor will be 7079 closed. If the caller desires that this file descriptor be cached by 7080 BFD (opened as needed, closed as needed to free descriptors for other 7081 opens), with the supplied FD used as an initial file descriptor (but 7082 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the 7083 returned BFD. The default is to assume no caching; the file descriptor 7084 will remain open until `bfd_close', and will not be affected by BFD 7085 operations on other files. 7086 7087 Possible errors are `bfd_error_no_memory', 7088 `bfd_error_invalid_target' and `bfd_error_system_call'. 7089 7090 2.14.1.4 `bfd_openstreamr' 7091 .......................... 7092 7093 *Synopsis* 7094 bfd *bfd_openstreamr (const char *, const char *, void *); 7095 *Description* 7096 Open a BFD for read access on an existing stdio stream.

The STREAM is 7119 created using OPEN_FUNC, accessed using PREAD_FUNC and destroyed using 7120 CLOSE_FUNC. 7121 7122 Calls `bfd_find_target', so TARGET is interpreted as by that 7123 function. 7124 7125 Calls OPEN_FUNC (which can call `bfd_zalloc' and `bfd_get_filename') 7126 to obtain the read-only stream backing the BFD. OPEN_FUNC either 7127 succeeds returning the non-`NULL' STREAM, or fails returning `NULL' 7128 (setting `bfd_error'). 7129 7130 Calls PREAD_FUNC to request NBYTES of data from STREAM starting at 7131 OFFSET (e.g., via a call to `bfd_read'). PREAD_FUNC either succeeds 7132 returning the number of bytes read (which can be less than NBYTES when 7133 end-of-file), or fails returning -1 (setting `bfd_error'). 7134 7135 Calls CLOSE_FUNC when the BFD is later closed using `bfd_close'. 7136 CLOSE_FUNC either succeeds returning 0, or fails returning -1 (setting 7137 `bfd_error'). 7138 7139 Calls STAT_FUNC to fill in a stat structure for bfd_stat, 7140 bfd_get_size, and bfd_get_mtime calls. STAT_FUNC returns 0 on success, 7141 or returns -1 on failure (setting `bfd_error'). 7142 7143 If `bfd_openr_iovec' returns `NULL' then an error has occurred. 7144 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target' 7145 and `bfd_error_system_call'. 7146 7147 2.14.1.6 `bfd_openw' 7148 .................... 7149 7150 *Synopsis* 7151 bfd *bfd_openw (const char *filename, const char *target); 7152 *Description* 7153 Create a BFD, associated with file FILENAME, using the file format 7154 TARGET, and return a pointer to it. 7155 7156 Possible errors are `bfd_error_system_call', `bfd_error_no_memory', 7157 `bfd_error_invalid_target'. 7158 7159 2.14.1.7 `bfd_close' 7160 .................... 7161 7162 *Synopsis* 7163 bfd_boolean bfd_close (bfd *abfd); 7164 *Description* 7165 Close a BFD.

This routine would be used if the application had 7185 just used BFD for swapping and didn't want to use any of the writing 7186 code. 7187 7188 If the created file is executable, then `chmod' is called to mark it 7189 as such. 7190 7191 All memory attached to the BFD is released. 7192 7193 *Returns* 7194 `TRUE' is returned if all is ok, otherwise `FALSE'. 7195 7196 2.14.1.9 `bfd_create' 7197 ..................... 7198 7199 *Synopsis* 7200 bfd *bfd_create (const char *filename, bfd *templ); 7201 *Description* 7202 Create a new BFD in the manner of `bfd_openw', but without opening a 7203 file.

It then 7324 searches the filesystem for this .debug file in some standard 7325 locations, including the directory tree rooted at DIR, and if found 7326 returns the full filename. 7327 7328 If DIR is NULL, it will search a default path configured into libbfd 7329 at build time. [XXX this feature is not currently implemented]. 7330 7331 *Returns* 7332 `NULL' on any errors or failure to locate the .debug file, otherwise a 7333 pointer to a heap-allocated string containing the filename.

The mangling performs any necessary endian 7397 translations and removes alignment restrictions. Note that types 7398 accepted and returned by these macros are identical so they can be 7399 swapped around in macros--for example, `libaout.h' defines `GET_WORD' 7400 to either `bfd_get_32' or `bfd_get_64'. 7401 7402 In the put routines, VAL must be a `bfd_vma'. If we are on a system 7403 without prototypes, the caller is responsible for making sure that is 7404 true, with a cast if necessary. We don't cast them in the macro 7405 definitions because that would prevent `lint' or `gcc -Wall' from 7406 detecting sins such as passing a pointer. To detect calling these with 7407 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit 7408 `bfd_vma''s. 7409 7410 /* Byte swapping macros for user section data. */ 7411 7412 #define bfd_put_8(abfd, val, ptr) \ 7413 ((void) (*((unsigned char *) (ptr)) = (val) & 0xff)) 7414 #define bfd_put_signed_8 \ 7415 bfd_put_8 7416 #define bfd_get_8(abfd, ptr) \ 7417 (*(unsigned char *) (ptr) & 0xff) 7418 #define bfd_get_signed_8(abfd, ptr) \ 7419 (((*(unsigned char *) (ptr) & 0xff) ^ 0x80) - 0x80) 7420 7421 #define bfd_put_16(abfd, val, ptr) \ 7422 BFD_SEND (abfd, bfd_putx16, ((val),(ptr))) 7423 #define bfd_put_signed_16 \ 7424 bfd_put_16 7425 #define bfd_get_16(abfd, ptr) \ 7426 BFD_SEND (abfd, bfd_getx16, (ptr)) 7427 #define bfd_get_signed_16(abfd, ptr) \ 7428 BFD_SEND (abfd, bfd_getx_signed_16, (ptr)) 7429 7430 #define bfd_put_32(abfd, val, ptr) \ 7431 BFD_SEND (abfd, bfd_putx32, ((val),(ptr))) 7432 #define bfd_put_signed_32 \ 7433 bfd_put_32 7434 #define bfd_get_32(abfd, ptr) \ 7435 BFD_SEND (abfd, bfd_getx32, (ptr)) 7436 #define bfd_get_signed_32(abfd, ptr) \ 7437 BFD_SEND (abfd, bfd_getx_signed_32, (ptr)) 7438 7439 #define bfd_put_64(abfd, val, ptr) \ 7440 BFD_SEND (abfd, bfd_putx64, ((val), (ptr))) 7441 #define bfd_put_signed_64 \ 7442 bfd_put_64 7443 #define bfd_get_64(abfd, ptr) \ 7444 BFD_SEND (abfd, bfd_getx64, (ptr)) 7445 #define bfd_get_signed_64(abfd, ptr) \ 7446 BFD_SEND (abfd, bfd_getx_signed_64, (ptr)) 7447 7448 #define bfd_get(bits, abfd, ptr) \ 7449 ((bits) == 8 ?

The module in `cache.c' maintains a least recently used 7548 list of `BFD_CACHE_MAX_OPEN' files, and exports the name 7549 `bfd_cache_lookup', which runs around and makes sure that the required 7550 BFD is open.

The third routine takes all the object files and links them 7617 together to create the output file. These routines are designed so 7618 that the linker proper does not need to know anything about the symbols 7619 in the object files that it is linking. The linker merely arranges the 7620 sections as directed by the linker script and lets BFD handle the 7621 details of symbols and relocs. 7622 7623 The second routine and third routines are passed a pointer to a 7624 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds 7625 information relevant to the link, including the linker hash table 7626 (which was created by the first routine) and a set of callback 7627 functions to the linker proper. 7628 7629 The generic linker routines are in `linker.c', and use the header 7630 file `genlink.h'. As of this writing, the only back ends which have 7631 implemented versions of these routines are a.out (in `aoutx.h') and 7632 ECOFF (in `ecoff.c'). The a.out routines are used as examples 7633 throughout this section. 7634 7635 * Menu: 7636 7637 * Creating a Linker Hash Table:: 7638 * Adding Symbols to the Hash Table:: 7639 * Performing the Final Link:: 7640 7641 7642 File: bfd.info, Node: Creating a Linker Hash Table, Next: Adding Symbols to the Hash Table, Prev: Linker Functions, Up: Linker Functions 7643 7644 2.17.1 Creating a linker hash table 7645 ----------------------------------- 7646 7647 The linker routines must create a hash table, which must be derived 7648 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash 7649 Tables::, for information on how to create a derived hash table. This 7650 entry point is called using the target vector of the linker output file. 7651 7652 The `_bfd_link_hash_table_create' entry point must allocate and 7653 initialize an instance of the desired hash table. If the back end does 7654 not require any additional information to be stored with the entries in 7655 the hash table, the entry point may simply create a `struct 7656 bfd_link_hash_table'. Most likely, however, some additional 7657 information will be needed. 7658 7659 For example, with each entry in the hash table the a.out linker 7660 keeps the index the symbol has in the final output file (this index 7661 number is used so that when doing a relocatable link the symbol index 7662 used in the output file can be quickly filled in when copying over a 7663 reloc). The a.out linker code defines the required structures and 7664 functions for a hash table derived from `struct bfd_link_hash_table'. 7665 The a.out linker hash table is created by the function 7666 `NAME(aout,link_hash_table_create)'; it simply allocates space for the 7667 hash table, initializes it, and returns a pointer to it. 7668 7669 When writing the linker routines for a new back end, you will 7670 generally not know exactly which fields will be required until you have 7671 finished. You should simply create a new hash table which defines no 7672 additional fields, and then simply add fields as they become necessary. 7673 7674 7675 File: bfd.info, Node: Adding Symbols to the Hash Table, Next: Performing the Final Link, Prev: Creating a Linker Hash Table, Up: Linker Functions 7676 7677 2.17.2 Adding symbols to the hash table 7678 --------------------------------------- 7679 7680 The linker proper will call the `_bfd_link_add_symbols' entry point for 7681 each object file or archive which is to be linked (typically these are 7682 the files named on the command line, but some may also come from the 7683 linker script). The entry point is responsible for examining the file. 7684 For an object file, BFD must add any relevant symbol information to the 7685 hash table. For an archive, BFD must determine which elements of the 7686 archive should be used and adding them to the link. 7687 7688 The a.out version of this entry point is 7689 `NAME(aout,link_add_symbols)'. 7690 7691 * Menu: 7692 7693 * Differing file formats:: 7694 * Adding symbols from an object file:: 7695 * Adding symbols from an archive:: 7696 7697 7698 File: bfd.info, Node: Differing file formats, Next: Adding symbols from an object file, Prev: Adding Symbols to the Hash Table, Up: Adding Symbols to the Hash Table 7699 7700 2.17.2.1 Differing file formats 7701 ............................... 7702 7703 Normally all the files involved in a link will be of the same format, 7704 but it is also possible to link together different format object files, 7705 and the back end must support that. The `_bfd_link_add_symbols' entry 7706 point is called via the target vector of the file to be added. This 7707 has an important consequence: the function may not assume that the hash 7708 table is the type created by the corresponding 7709 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols' 7710 function can assume about the hash table is that it is derived from 7711 `struct bfd_link_hash_table'. 7712 7713 Sometimes the `_bfd_link_add_symbols' function must store some 7714 information in the hash table entry to be used by the `_bfd_final_link' 7715 function. In such a case the output bfd xvec must be checked to make 7716 sure that the hash table was created by an object file of the same 7717 format. 7718 7719 The `_bfd_final_link' routine must be prepared to handle a hash 7720 entry without any extra information added by the 7721 `_bfd_link_add_symbols' function. A hash entry without extra 7722 information will also occur when the linker script directs the linker 7723 to create a symbol. Note that, regardless of how a hash table entry is 7724 added, all the fields will be initialized to some sort of null value by 7725 the hash table entry initialization function. 7726 7727 See `ecoff_link_add_externals' for an example of how to check the 7728 output bfd before saving information (in this case, the ECOFF external 7729 symbol debugging information) in a hash table entry. 7730 7731 7732 File: bfd.info, Node: Adding symbols from an object file, Next: Adding symbols from an archive, Prev: Differing file formats, Up: Adding Symbols to the Hash Table 7733 7734 2.17.2.2 Adding symbols from an object file 7735 ........................................... 7736 7737 When the `_bfd_link_add_symbols' routine is passed an object file, it 7738 must add all externally visible symbols in that object file to the hash 7739 table. The actual work of adding the symbol to the hash table is 7740 normally handled by the function `_bfd_generic_link_add_one_symbol'. 7741 The `_bfd_link_add_symbols' routine is responsible for reading all the 7742 symbols from the object file and passing the correct information to 7743 `_bfd_generic_link_add_one_symbol'. 7744 7745 The `_bfd_link_add_symbols' routine should not use 7746 `bfd_canonicalize_symtab' to read the symbols. The point of providing 7747 this routine is to avoid the overhead of converting the symbols into 7748 generic `asymbol' structures. 7749 7750 `_bfd_generic_link_add_one_symbol' handles the details of combining 7751 common symbols, warning about multiple definitions, and so forth. It 7752 takes arguments which describe the symbol to add, notably symbol flags, 7753 a section, and an offset. The symbol flags include such things as 7754 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object 7755 file, or something like `bfd_und_section_ptr' for an undefined symbol 7756 or `bfd_com_section_ptr' for a common symbol. 7757 7758 If the `_bfd_final_link' routine is also going to need to read the 7759 symbol information, the `_bfd_link_add_symbols' routine should save it 7760 somewhere attached to the object file BFD. However, the information 7761 should only be saved if the `keep_memory' field of the `info' argument 7762 is TRUE, so that the `-no-keep-memory' linker switch is effective. 7763 7764 The a.out function which adds symbols from an object file is 7765 `aout_link_add_object_symbols', and most of the interesting work is in 7766 `aout_link_add_symbols'. The latter saves pointers to the hash tables 7767 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol 7768 number, so that the `_bfd_final_link' routine does not have to call the 7769 hash table lookup routine to locate the entry. 7770 7771 7772 File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table 7773 7774 2.17.2.3 Adding symbols from an archive 7775 ....................................... 7776 7777 When the `_bfd_link_add_symbols' routine is passed an archive, it must 7778 look through the symbols defined by the archive and decide which 7779 elements of the archive should be included in the link. For each such 7780 element it must call the `add_archive_element' linker callback, and it 7781 must add the symbols from the object file to the linker hash table. 7782 (The callback may in fact indicate that a replacement BFD should be 7783 used, in which case the symbols from that BFD should be added to the 7784 linker hash table instead.) 7785 7786 In most cases the work of looking through the symbols in the archive 7787 should be done by the `_bfd_generic_link_add_archive_symbols' function. 7788 This function builds a hash table from the archive symbol table and 7789 looks through the list of undefined symbols to see which elements 7790 should be included. `_bfd_generic_link_add_archive_symbols' is passed 7791 a function to call to make the final decision about adding an archive 7792 element to the link and to do the actual work of adding the symbols to 7793 the linker hash table. 7794 7795 The function passed to `_bfd_generic_link_add_archive_symbols' must 7796 read the symbols of the archive element and decide whether the archive 7797 element should be included in the link. If the element is to be 7798 included, the `add_archive_element' linker callback routine must be 7799 called with the element as an argument, and the element's symbols must 7800 be added to the linker hash table just as though the element had itself 7801 been passed to the `_bfd_link_add_symbols' function. The 7802 `add_archive_element' callback has the option to indicate that it would 7803 like to replace the element archive with a substitute BFD, in which 7804 case it is the symbols of that substitute BFD that must be added to the 7805 linker hash table instead. 7806 7807 When the a.out `_bfd_link_add_symbols' function receives an archive, 7808 it calls `_bfd_generic_link_add_archive_symbols' passing 7809 `aout_link_check_archive_element' as the function argument. 7810 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'. 7811 If the latter decides to add the element (an element is only added if 7812 it provides a real, non-common, definition for a previously undefined 7813 or common symbol) it calls the `add_archive_element' callback and then 7814 `aout_link_check_archive_element' calls `aout_link_add_symbols' to 7815 actually add the symbols to the linker hash table - possibly those of a 7816 substitute BFD, if the `add_archive_element' callback avails itself of 7817 that option. 7818 7819 The ECOFF back end is unusual in that it does not normally call 7820 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already 7821 contain a hash table of symbols. The ECOFF back end searches the 7822 archive itself to avoid the overhead of creating a new hash table. 7823 7824 7825 File: bfd.info, Node: Performing the Final Link, Prev: Adding Symbols to the Hash Table, Up: Linker Functions 7826 7827 2.17.3 Performing the final link 7828 -------------------------------- 7829 7830 When all the input files have been processed, the linker calls the 7831 `_bfd_final_link' entry point of the output BFD. This routine is 7832 responsible for producing the final output file, which has several 7833 aspects. It must relocate the contents of the input sections and copy 7834 the data into the output sections. It must build an output symbol 7835 table including any local symbols from the input files and the global 7836 symbols from the hash table. When producing relocatable output, it must 7837 modify the input relocs and write them into the output file. There may 7838 also be object format dependent work to be done. 7839 7840 The linker will also call the `write_object_contents' entry point 7841 when the BFD is closed. The two entry points must work together in 7842 order to produce the correct output file. 7843 7844 The details of how this works are inevitably dependent upon the 7845 specific object file format. The a.out `_bfd_final_link' routine is 7846 `NAME(aout,final_link)'. 7847 7848 * Menu: 7849 7850 * Information provided by the linker:: 7851 * Relocating the section contents:: 7852 * Writing the symbol table:: 7853 7854 7855 File: bfd.info, Node: Information provided by the linker, Next: Relocating the section contents, Prev: Performing the Final Link, Up: Performing the Final Link 7856 7857 2.17.3.1 Information provided by the linker 7858 ........................................... 7859 7860 Before the linker calls the `_bfd_final_link' entry point, it sets up 7861 some data structures for the function to use. 7862 7863 The `input_bfds' field of the `bfd_link_info' structure will point 7864 to a list of all the input files included in the link. These files are 7865 linked through the `link_next' field of the `bfd' structure. 7866 7867 Each section in the output file will have a list of `link_order' 7868 structures attached to the `map_head.link_order' field (the 7869 `link_order' structure is defined in `bfdlink.h'). These structures 7870 describe how to create the contents of the output section in terms of 7871 the contents of various input sections, fill constants, and, 7872 eventually, other types of information. They also describe relocs that 7873 must be created by the BFD backend, but do not correspond to any input 7874 file; this is used to support -Ur, which builds constructors while 7875 generating a relocatable object file. 7876 7877 7878 File: bfd.info, Node: Relocating the section contents, Next: Writing the symbol table, Prev: Information provided by the linker, Up: Performing the Final Link 7879 7880 2.17.3.2 Relocating the section contents 7881 ........................................ 7882 7883 The `_bfd_final_link' function should look through the `link_order' 7884 structures attached to each section of the output file. Each 7885 `link_order' structure should either be handled specially, or it should 7886 be passed to the function `_bfd_default_link_order' which will do the 7887 right thing (`_bfd_default_link_order' is defined in `linker.c'). 7888 7889 For efficiency, a `link_order' of type `bfd_indirect_link_order' 7890 whose associated section belongs to a BFD of the same format as the 7891 output BFD must be handled specially. This type of `link_order' 7892 describes part of an output section in terms of a section belonging to 7893 one of the input files. The `_bfd_final_link' function should read the 7894 contents of the section and any associated relocs, apply the relocs to 7895 the section contents, and write out the modified section contents. If 7896 performing a relocatable link, the relocs themselves must also be 7897 modified and written out. 7898 7899 The functions `_bfd_relocate_contents' and 7900 `_bfd_final_link_relocate' provide some general support for performing 7901 the actual relocations, notably overflow checking. Their arguments 7902 include information about the symbol the relocation is against and a 7903 `reloc_howto_type' argument which describes the relocation to perform. 7904 These functions are defined in `reloc.c'. 7905 7906 The a.out function which handles reading, relocating, and writing 7907 section contents is `aout_link_input_section'. The actual relocation 7908 is done in `aout_link_input_section_std' and 7909 `aout_link_input_section_ext'. 7910 7911 7912 File: bfd.info, Node: Writing the symbol table, Prev: Relocating the section contents, Up: Performing the Final Link 7913 7914 2.17.3.3 Writing the symbol table 7915 ................................. 7916 7917 The `_bfd_final_link' function must gather all the symbols in the input 7918 files and write them out. It must also write out all the symbols in 7919 the global hash table. This must be controlled by the `strip' and 7920 `discard' fields of the `bfd_link_info' structure. 7921 7922 The local symbols of the input files will not have been entered into 7923 the linker hash table. The `_bfd_final_link' routine must consider 7924 each input file and include the symbols in the output file. It may be 7925 convenient to do this when looking through the `link_order' structures, 7926 or it may be done by stepping through the `input_bfds' list. 7927 7928 The `_bfd_final_link' routine must also traverse the global hash 7929 table to gather all the externally visible symbols. It is possible 7930 that most of the externally visible symbols may be written out when 7931 considering the symbols of each input file, but it is still necessary 7932 to traverse the hash table since the linker script may have defined 7933 some symbols that are not in any of the input files. 7934 7935 The `strip' field of the `bfd_link_info' structure controls which 7936 symbols are written out. The possible values are listed in 7937 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field 7938 of the `bfd_link_info' structure is a hash table of symbols to keep; 7939 each symbol should be looked up in this hash table, and only symbols 7940 which are present should be included in the output file. 7941 7942 If the `strip' field of the `bfd_link_info' structure permits local 7943 symbols to be written out, the `discard' field is used to further 7944 controls which local symbols are included in the output file. If the 7945 value is `discard_l', then all local symbols which begin with a certain 7946 prefix are discarded; this is controlled by the 7947 `bfd_is_local_label_name' entry point. 7948 7949 The a.out backend handles symbols by calling 7950 `aout_link_write_symbols' on each input BFD and then traversing the 7951 global hash table with the function `aout_link_write_other_symbol'. It 7952 builds a string table while writing out the symbols, which is written 7953 to the output file at the end of `NAME(aout,final_link)'. 7954 7955 2.17.3.4 `bfd_link_split_section' 7956 ................................. 7957 7958 *Synopsis* 7959 bfd_boolean bfd_link_split_section (bfd *abfd, asection *sec); 7960 *Description* 7961 Return nonzero if SEC should be split during a reloceatable or final 7962 link. 7963 #define bfd_link_split_section(abfd, sec) \ 7964 BFD_SEND (abfd, _bfd_link_split_section, (abfd, sec)) 7965 7966 2.17.3.5 `bfd_section_already_linked' 7967 ..................................... 7968 7969 *Synopsis* 7970 void bfd_section_already_linked (bfd *abfd, asection *sec, 7971 struct bfd_link_info *info); 7972 *Description* 7973 Check if SEC has been already linked during a reloceatable or final 7974 link. 7975 #define bfd_section_already_linked(abfd, sec, info) \ 7976 BFD_SEND (abfd, _section_already_linked, (abfd, sec, info)) 7977 7978 2.17.3.6 `bfd_generic_define_common_symbol' 7979 ........................................... 7980 7981 *Synopsis* 7982 bfd_boolean bfd_generic_define_common_symbol 7983 (bfd *output_bfd, struct bfd_link_info *info, 7984 struct bfd_link_hash_entry *h); 7985 *Description* 7986 Convert common symbol H into a defined symbol.

Routines are 8010 provided to initialize a hash table, to free a hash table, to look up a 8011 string in a hash table and optionally create an entry for it, and to 8012 traverse a hash table. There is currently no routine to delete an 8013 string from a hash table. 8014 8015 The basic hash table does not permit any data to be stored with a 8016 string. However, a hash table is designed to present a base class from 8017 which other types of hash tables may be derived. These derived types 8018 may store additional information with the string. Hash tables were 8019 implemented in this way, rather than simply providing a data pointer in 8020 a hash table entry, because they were designed for use by the linker 8021 back ends. The linker may create thousands of hash table entries, and 8022 the overhead of allocating private data and storing and following 8023 pointers becomes noticeable. 8024 8025 The basic hash table code is in `hash.c'. 8026 8027 * Menu: 8028 8029 * Creating and Freeing a Hash Table:: 8030 * Looking Up or Entering a String:: 8031 * Traversing a Hash Table:: 8032 * Deriving a New Hash Table Type:: 8033 8034 8035 File: bfd.info, Node: Creating and Freeing a Hash Table, Next: Looking Up or Entering a String, Prev: Hash Tables, Up: Hash Tables 8036 8037 2.18.1 Creating and freeing a hash table 8038 ---------------------------------------- 8039 8040 To create a hash table, create an instance of a `struct bfd_hash_table' 8041 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know 8042 approximately how many entries you will need, the function 8043 `bfd_hash_table_init_n', which takes a SIZE argument, may be used). 8044 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs. 8045 8046 The function `bfd_hash_table_init' take as an argument a function to 8047 use to create new entries. For a basic hash table, use the function 8048 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why 8049 you would want to use a different value for this argument. 8050 8051 `bfd_hash_table_init' will create an objalloc which will be used to 8052 allocate new entries. You may allocate memory on this objalloc using 8053 `bfd_hash_allocate'. 8054 8055 Use `bfd_hash_table_free' to free up all the memory that has been 8056 allocated for a hash table. This will not free up the `struct 8057 bfd_hash_table' itself, which you must provide. 8058 8059 Use `bfd_hash_set_default_size' to set the default size of hash 8060 table to use. 8061 8062 8063 File: bfd.info, Node: Looking Up or Entering a String, Next: Traversing a Hash Table, Prev: Creating and Freeing a Hash Table, Up: Hash Tables 8064 8065 2.18.2 Looking up or entering a string 8066 -------------------------------------- 8067 8068 The function `bfd_hash_lookup' is used both to look up a string in the 8069 hash table and to create a new entry. 8070 8071 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a 8072 string. If the string is found, it will returns a pointer to a `struct 8073 bfd_hash_entry'. If the string is not found in the table 8074 `bfd_hash_lookup' will return `NULL'. You should not modify any of the 8075 fields in the returns `struct bfd_hash_entry'. 8076 8077 If the CREATE argument is `TRUE', the string will be entered into 8078 the hash table if it is not already there. Either way a pointer to a 8079 `struct bfd_hash_entry' will be returned, either to the existing 8080 structure or to a newly created one. In this case, a `NULL' return 8081 means that an error occurred. 8082 8083 If the CREATE argument is `TRUE', and a new entry is created, the 8084 COPY argument is used to decide whether to copy the string onto the 8085 hash table objalloc or not. If COPY is passed as `FALSE', you must be 8086 careful not to deallocate or modify the string as long as the hash table 8087 exists. 8088 8089 8090 File: bfd.info, Node: Traversing a Hash Table, Next: Deriving a New Hash Table Type, Prev: Looking Up or Entering a String, Up: Hash Tables 8091 8092 2.18.3 Traversing a hash table 8093 ------------------------------ 8094 8095 The function `bfd_hash_traverse' may be used to traverse a hash table, 8096 calling a function on each element. The traversal is done in a random 8097 order. 8098 8099 `bfd_hash_traverse' takes as arguments a function and a generic 8100 `void *' pointer. The function is called with a hash table entry (a 8101 `struct bfd_hash_entry *') and the generic pointer passed to 8102 `bfd_hash_traverse'. The function must return a `boolean' value, which 8103 indicates whether to continue traversing the hash table. If the 8104 function returns `FALSE', `bfd_hash_traverse' will stop the traversal 8105 and return immediately. 8106 8107 8108 File: bfd.info, Node: Deriving a New Hash Table Type, Prev: Traversing a Hash Table, Up: Hash Tables 8109 8110 2.18.4 Deriving a new hash table type 8111 ------------------------------------- 8112 8113 Many uses of hash tables want to store additional information which 8114 each entry in the hash table. Some also find it convenient to store 8115 additional information with the hash table itself. This may be done 8116 using a derived hash table. 8117 8118 Since C is not an object oriented language, creating a derived hash 8119 table requires sticking together some boilerplate routines with a few 8120 differences specific to the type of hash table you want to create. 8121 8122 An example of a derived hash table is the linker hash table. The 8123 structures for this are defined in `bfdlink.h'. The functions are in 8124 `linker.c'. 8125 8126 You may also derive a hash table from an already derived hash table. 8127 For example, the a.out linker backend code uses a hash table derived 8128 from the linker hash table. 8129 8130 * Menu: 8131 8132 * Define the Derived Structures:: 8133 * Write the Derived Creation Routine:: 8134 * Write Other Derived Routines:: 8135 8136 8137 File: bfd.info, Node: Define the Derived Structures, Next: Write the Derived Creation Routine, Prev: Deriving a New Hash Table Type, Up: Deriving a New Hash Table Type 8138 8139 2.18.4.1 Define the derived structures 8140 ...................................... 8141 8142 You must define a structure for an entry in the hash table, and a 8143 structure for the hash table itself. 8144 8145 The first field in the structure for an entry in the hash table must 8146 be of the type used for an entry in the hash table you are deriving 8147 from. If you are deriving from a basic hash table this is `struct 8148 bfd_hash_entry', which is defined in `bfd.h'. The first field in the 8149 structure for the hash table itself must be of the type of the hash 8150 table you are deriving from itself. If you are deriving from a basic 8151 hash table, this is `struct bfd_hash_table'. 8152 8153 For example, the linker hash table defines `struct 8154 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of 8155 type `struct bfd_hash_entry'. Similarly, the first field in `struct 8156 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'. 8157 8158 8159 File: bfd.info, Node: Write the Derived Creation Routine, Next: Write Other Derived Routines, Prev: Define the Derived Structures, Up: Deriving a New Hash Table Type 8160 8161 2.18.4.2 Write the derived creation routine 8162 ........................................... 8163 8164 You must write a routine which will create and initialize an entry in 8165 the hash table. This routine is passed as the function argument to 8166 `bfd_hash_table_init'. 8167 8168 In order to permit other hash tables to be derived from the hash 8169 table you are creating, this routine must be written in a standard way. 8170 8171 The first argument to the creation routine is a pointer to a hash 8172 table entry. This may be `NULL', in which case the routine should 8173 allocate the right amount of space. Otherwise the space has already 8174 been allocated by a hash table type derived from this one. 8175 8176 After allocating space, the creation routine must call the creation 8177 routine of the hash table type it is derived from, passing in a pointer 8178 to the space it just allocated. This will initialize any fields used 8179 by the base hash table. 8180 8181 Finally the creation routine must initialize any local fields for 8182 the new hash table type. 8183 8184 Here is a boilerplate example of a creation routine. FUNCTION_NAME 8185 is the name of the routine. ENTRY_TYPE is the type of an entry in the 8186 hash table you are creating. BASE_NEWFUNC is the name of the creation 8187 routine of the hash table type your hash table is derived from. 8188 8189 struct bfd_hash_entry * 8190 FUNCTION_NAME (struct bfd_hash_entry *entry, 8191 struct bfd_hash_table *table, 8192 const char *string) 8193 { 8194 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry; 8195 8196 /* Allocate the structure if it has not already been allocated by a 8197 derived class. */ 8198 if (ret == NULL) 8199 { 8200 ret = bfd_hash_allocate (table, sizeof (* ret)); 8201 if (ret == NULL) 8202 return NULL; 8203 } 8204 8205 /* Call the allocation method of the base class. */ 8206 ret = ((ENTRY_TYPE *) 8207 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string)); 8208 8209 /* Initialize the local fields here. */ 8210 8211 return (struct bfd_hash_entry *) ret; 8212 } 8213 *Description* 8214 The creation routine for the linker hash table, which is in `linker.c', 8215 looks just like this example. FUNCTION_NAME is 8216 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'. 8217 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic 8218 hash table. 8219 8220 `_bfd_link_hash_newfunc' also initializes the local fields in a 8221 linker hash table entry: `type', `written' and `next'. 8222 8223 8224 File: bfd.info, Node: Write Other Derived Routines, Prev: Write the Derived Creation Routine, Up: Deriving a New Hash Table Type 8225 8226 2.18.4.3 Write other derived routines 8227 ..................................... 8228 8229 You will want to write other routines for your new hash table, as well. 8230 8231 You will want an initialization routine which calls the 8232 initialization routine of the hash table you are deriving from and 8233 initializes any other local fields. For the linker hash table, this is 8234 `_bfd_link_hash_table_init' in `linker.c'. 8235 8236 You will want a lookup routine which calls the lookup routine of the 8237 hash table you are deriving from and casts the result. The linker hash 8238 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an 8239 additional argument which it uses to decide how to return the looked up 8240 value). 8241 8242 You may want a traversal routine. This should just call the 8243 traversal routine of the hash table you are deriving from with 8244 appropriate casts. The linker hash table uses `bfd_link_hash_traverse' 8245 in `linker.c'. 8246 8247 These routines may simply be defined as macros. For example, the 8248 a.out backend linker hash table, which is derived from the linker hash 8249 table, uses macros for the lookup and traversal routines. These are 8250 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h. 8251 8252 8253 File: bfd.info, Node: BFD back ends, Next: GNU Free Documentation License, Prev: BFD front end, Up: Top 8254 8255 3 BFD back ends 8256 *************** 8257 8258 * Menu: 8259 8260 * What to Put Where:: 8261 * aout :: a.out backends 8262 * coff :: coff backends 8263 * elf :: elf backends 8264 * mmo :: mmo backend 8265 8266 8267 File: bfd.info, Node: What to Put Where, Next: aout, Prev: BFD back ends, Up: BFD back ends 8268 8269 3.1 What to Put Where 8270 ===================== 8271 8272 All of BFD lives in one directory. 8273 8274 8275 File: bfd.info, Node: aout, Next: coff, Prev: What to Put Where, Up: BFD back ends 8276 8277 3.2 a.out backends 8278 ================== 8279 8280 *Description* 8281 BFD supports a number of different flavours of a.out format, though the 8282 major differences are only the sizes of the structures on disk, and the 8283 shape of the relocation information. 8284 8285 The support is split into a basic support file `aoutx.h' and other 8286 files which derive functions from the base. One derivation file is 8287 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions 8288 support for sun3, sun4, 386 and 29k a.out files, to create a target 8289 jump vector for a specific target. 8290 8291 This information is further split out into more specific files for 8292 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for 8293 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out 8294 format. 8295 8296 The base file `aoutx.h' defines general mechanisms for reading and 8297 writing records to and from disk and various other methods which BFD 8298 requires. It is included by `aout32.c' and `aout64.c' to form the names 8299 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc. 8300 8301 As an example, this is what goes on to make the back end for a sun4, 8302 from `aout32.c': 8303 8304 #define ARCH_SIZE 32 8305 #include "aoutx.h" 8306 8307 Which exports names: 8308 8309 ... 8310 aout_32_canonicalize_reloc 8311 aout_32_find_nearest_line 8312 aout_32_get_lineno 8313 aout_32_get_reloc_upper_bound 8314 ... 8315 8316 from `sunos.c': 8317 8318 #define TARGET_NAME "a.out-sunos-big" 8319 #define VECNAME sunos_big_vec 8320 #include "aoutf1.h" 8321 8322 requires all the names from `aout32.c', and produces the jump vector 8323 8324 sunos_big_vec 8325 8326 The file `host-aout.c' is a special case. It is for a large set of 8327 hosts that use "more or less standard" a.out files, and for which 8328 cross-debugging is not interesting. It uses the standard 32-bit a.out 8329 support routines, but determines the file offsets and addresses of the 8330 text, data, and BSS sections, the machine architecture and machine 8331 type, and the entry point address, in a host-dependent manner. Once 8332 these values have been determined, generic code is used to handle the 8333 object file. 8334 8335 When porting it to run on a new system, you must supply: 8336 8337 HOST_PAGE_SIZE 8338 HOST_SEGMENT_SIZE 8339 HOST_MACHINE_ARCH (optional) 8340 HOST_MACHINE_MACHINE (optional) 8341 HOST_TEXT_START_ADDR 8342 HOST_STACK_END_ADDR 8343 8344 in the file `../include/sys/h-XXX.h' (for your host). These values, 8345 plus the structures and macros defined in `a.out.h' on your host 8346 system, will produce a BFD target that will access ordinary a.out files 8347 on your host. To configure a new machine to use `host-aout.c', specify: 8348 8349 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec 8350 TDEPFILES= host-aout.o trad-core.o 8351 8352 in the `config/XXX.mt' file, and modify `configure.in' to use the 8353 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration 8354 is selected. 8355 8356 3.2.1 Relocations 8357 ----------------- 8358 8359 *Description* 8360 The file `aoutx.h' provides for both the _standard_ and _extended_ 8361 forms of a.out relocation records. 8362 8363 The standard records contain only an address, a symbol index, and a 8364 type field. The extended records (used on 29ks and sparcs) also have a 8365 full integer for an addend. 8366 8367 3.2.2 Internal entry points 8368 --------------------------- 8369 8370 *Description* 8371 `aoutx.h' exports several routines for accessing the contents of an 8372 a.out file, which are gathered and exported in turn by various format 8373 specific files (eg sunos.c). 8374 8375 3.2.2.1 `aout_SIZE_swap_exec_header_in' 8376 ....................................... 8377 8378 *Synopsis* 8379 void aout_SIZE_swap_exec_header_in, 8380 (bfd *abfd, 8381 struct external_exec *bytes, 8382 struct internal_exec *execp); 8383 *Description* 8384 Swap the information in an executable header RAW_BYTES taken from a raw 8385 byte stream memory image into the internal exec header structure EXECP. 8386 8387 3.2.2.2 `aout_SIZE_swap_exec_header_out' 8388 ........................................ 8389 8390 *Synopsis* 8391 void aout_SIZE_swap_exec_header_out 8392 (bfd *abfd, 8393 struct internal_exec *execp, 8394 struct external_exec *raw_bytes); 8395 *Description* 8396 Swap the information in an internal exec header structure EXECP into 8397 the buffer RAW_BYTES ready for writing to disk. 8398 8399 3.2.2.3 `aout_SIZE_some_aout_object_p' 8400 ...................................... 8401 8402 *Synopsis* 8403 const bfd_target *aout_SIZE_some_aout_object_p 8404 (bfd *abfd, 8405 struct internal_exec *execp, 8406 const bfd_target *(*callback_to_real_object_p) (bfd *)); 8407 *Description* 8408 Some a.out variant thinks that the file open in ABFD checking is an 8409 a.out file.

The major 8468 differences between formats are the sizes and alignments of fields in 8469 structures on disk, and the occasional extra field. 8470 8471 Coff in all its varieties is implemented with a few common files and 8472 a number of implementation specific files. For example, The 88k bcs 8473 coff format is implemented in the file `coff-m88k.c'. This file 8474 `#include's `coff/m88k.h' which defines the external structure of the 8475 coff format for the 88k, and `coff/internal.h' which defines the 8476 internal structure. `coff-m88k.c' also defines the relocations used by 8477 the 88k format *Note Relocations::. 8478 8479 The Intel i960 processor version of coff is implemented in 8480 `coff-i960.c'. This file has the same structure as `coff-m88k.c', 8481 except that it includes `coff/i960.h' rather than `coff-m88k.h'. 8482 8483 3.3.1 Porting to a new version of coff 8484 -------------------------------------- 8485 8486 The recommended method is to select from the existing implementations 8487 the version of coff which is most like the one you want to use. For 8488 example, we'll say that i386 coff is the one you select, and that your 8489 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy 8490 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines 8491 to `targets.c' and `Makefile.in' so that your new back end is used. 8492 Alter the shapes of the structures in `../include/coff/foo.h' so that 8493 they match what you need. You will probably also have to add `#ifdef's 8494 to the code in `coff/internal.h' and `coffcode.h' if your version of 8495 coff is too wild. 8496 8497 You can verify that your new BFD backend works quite simply by 8498 building `objdump' from the `binutils' directory, and making sure that 8499 its version of what's going on and your host system's idea (assuming it 8500 has the pretty standard coff dump utility, usually called `att-dump' or 8501 just `dump') are the same. Then clean up your code, and send what 8502 you've done to Cygnus. Then your stuff will be in the next release, and 8503 you won't have to keep integrating it. 8504 8505 3.3.2 How the coff backend works 8506 -------------------------------- 8507 8508 3.3.2.1 File layout 8509 ................... 8510 8511 The Coff backend is split into generic routines that are applicable to 8512 any Coff target and routines that are specific to a particular target. 8513 The target-specific routines are further split into ones which are 8514 basically the same for all Coff targets except that they use the 8515 external symbol format or use different values for certain constants. 8516 8517 The generic routines are in `coffgen.c'. These routines work for 8518 any Coff target. They use some hooks into the target specific code; 8519 the hooks are in a `bfd_coff_backend_data' structure, one of which 8520 exists for each target. 8521 8522 The essentially similar target-specific routines are in 8523 `coffcode.h'. This header file includes executable C code. The 8524 various Coff targets first include the appropriate Coff header file, 8525 make any special defines that are needed, and then include `coffcode.h'. 8526 8527 Some of the Coff targets then also have additional routines in the 8528 target source file itself. 8529 8530 For example, `coff-i960.c' includes `coff/internal.h' and 8531 `coff/i960.h'. It then defines a few constants, such as `I960', and 8532 includes `coffcode.h'. Since the i960 has complex relocation types, 8533 `coff-i960.c' also includes some code to manipulate the i960 relocs. 8534 This code is not in `coffcode.h' because it would not be used by any 8535 other target. 8536 8537 3.3.2.2 Coff long section names 8538 ............................... 8539 8540 In the standard Coff object format, section names are limited to the 8541 eight bytes available in the `s_name' field of the `SCNHDR' section 8542 header structure. The format requires the field to be NUL-padded, but 8543 not necessarily NUL-terminated, so the longest section names permitted 8544 are a full eight characters. 8545 8546 The Microsoft PE variants of the Coff object file format add an 8547 extension to support the use of long section names. This extension is 8548 defined in section 4 of the Microsoft PE/COFF specification (rev 8.1). 8549 If a section name is too long to fit into the section header's `s_name' 8550 field, it is instead placed into the string table, and the `s_name' 8551 field is filled with a slash ("/") followed by the ASCII decimal 8552 representation of the offset of the full name relative to the string 8553 table base. 8554 8555 Note that this implies that the extension can only be used in object 8556 files, as executables do not contain a string table. The standard 8557 specifies that long section names from objects emitted into executable 8558 images are to be truncated. 8559 8560 However, as a GNU extension, BFD can generate executable images that 8561 contain a string table and long section names. This would appear to be 8562 technically valid, as the standard only says that Coff debugging 8563 information is deprecated, not forbidden, and in practice it works, 8564 although some tools that parse PE files expecting the MS standard 8565 format may become confused; `PEview' is one known example. 8566 8567 The functionality is supported in BFD by code implemented under the 8568 control of the macro `COFF_LONG_SECTION_NAMES'. If not defined, the 8569 format does not support long section names in any way. If defined, it 8570 is used to initialise a flag, `_bfd_coff_long_section_names', and a 8571 hook function pointer, `_bfd_coff_set_long_section_names', in the Coff 8572 backend data structure. The flag controls the generation of long 8573 section names in output BFDs at runtime; if it is false, as it will be 8574 by default when generating an executable image, long section names are 8575 truncated; if true, the long section names extension is employed. The 8576 hook points to a function that allows the value of the flag to be 8577 altered at runtime, on formats that support long section names at all; 8578 on other formats it points to a stub that returns an error indication. 8579 With input BFDs, the flag is set according to whether any long section 8580 names are detected while reading the section headers. For a completely 8581 new BFD, the flag is set to the default for the target format. This 8582 information can be used by a client of the BFD library when deciding 8583 what output format to generate, and means that a BFD that is opened for 8584 read and subsequently converted to a writeable BFD and modified 8585 in-place will retain whatever format it had on input. 8586 8587 If `COFF_LONG_SECTION_NAMES' is simply defined (blank), or is 8588 defined to the value "1", then long section names are enabled by 8589 default; if it is defined to the value zero, they are disabled by 8590 default (but still accepted in input BFDs). The header `coffcode.h' 8591 defines a macro, `COFF_DEFAULT_LONG_SECTION_NAMES', which is used in 8592 the backends to initialise the backend data structure fields 8593 appropriately; see the comments for further detail. 8594 8595 3.3.2.3 Bit twiddling 8596 ..................... 8597 8598 Each flavour of coff supported in BFD has its own header file 8599 describing the external layout of the structures. There is also an 8600 internal description of the coff layout, in `coff/internal.h'. A major 8601 function of the coff backend is swapping the bytes and twiddling the 8602 bits to translate the external form of the structures into the normal 8603 internal form. This is all performed in the `bfd_swap'_thing_direction 8604 routines. Some elements are different sizes between different versions 8605 of coff; it is the duty of the coff version specific include file to 8606 override the definitions of various packing routines in `coffcode.h'. 8607 E.g., the size of line number entry in coff is sometimes 16 bits, and 8608 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO' 8609 will select the correct one. No doubt, some day someone will find a 8610 version of coff which has a varying field size not catered to at the 8611 moment. To port BFD, that person will have to add more `#defines'. 8612 Three of the bit twiddling routines are exported to `gdb'; 8613 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB' 8614 reads the symbol table on its own, but uses BFD to fix things up. More 8615 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out', 8616 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out', 8617 `coff_swap_filehdr_out', `coff_swap_aouthdr_out', 8618 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol 8619 table and reloc drudgery itself, thereby saving the internal BFD 8620 overhead, but uses BFD to swap things on the way out, making cross 8621 ports much safer. Doing so also allows BFD (and thus the linker) to 8622 use the same header files as `gas', which makes one avenue to disaster 8623 disappear. 8624 8625 3.3.2.4 Symbol reading 8626 ...................... 8627 8628 The simple canonical form for symbols used by BFD is not rich enough to 8629 keep all the information available in a coff symbol table. The back end 8630 gets around this problem by keeping the original symbol table around, 8631 "behind the scenes". 8632 8633 When a symbol table is requested (through a call to 8634 `bfd_canonicalize_symtab'), a request gets through to 8635 `coff_get_normalized_symtab'. This reads the symbol table from the coff 8636 file and swaps all the structures inside into the internal form. It 8637 also fixes up all the pointers in the table (represented in the file by 8638 offsets from the first symbol in the table) into physical pointers to 8639 elements in the new internal table. This involves some work since the 8640 meanings of fields change depending upon context: a field that is a 8641 pointer to another structure in the symbol table at one moment may be 8642 the size in bytes of a structure at the next. Another pass is made 8643 over the table. All symbols which mark file names (`C_FILE' symbols) 8644 are modified so that the internal string points to the value in the 8645 auxent (the real filename) rather than the normal text associated with 8646 the symbol (`".file"'). 8647 8648 At this time the symbol names are moved around. Coff stores all 8649 symbols less than nine characters long physically within the symbol 8650 table; longer strings are kept at the end of the file in the string 8651 table. This pass moves all strings into memory and replaces them with 8652 pointers to the strings. 8653 8654 The symbol table is massaged once again, this time to create the 8655 canonical table used by the BFD application. Each symbol is inspected 8656 in turn, and a decision made (using the `sclass' field) about the 8657 various flags to set in the `asymbol'. *Note Symbols::. The generated 8658 canonical table shares strings with the hidden internal symbol table. 8659 8660 Any linenumbers are read from the coff file too, and attached to the 8661 symbols which own the functions the linenumbers belong to. 8662 8663 3.3.2.5 Symbol writing 8664 ...................... 8665 8666 Writing a symbol to a coff file which didn't come from a coff file will 8667 lose any debugging information. The `asymbol' structure remembers the 8668 BFD from which the symbol was taken, and on output the back end makes 8669 sure that the same destination target as source target is present. 8670 8671 When the symbols have come from a coff file then all the debugging 8672 information is preserved. 8673 8674 Symbol tables are provided for writing to the back end in a vector 8675 of pointers to pointers. This allows applications like the linker to 8676 accumulate and output large symbol tables without having to do too much 8677 byte copying. 8678 8679 This function runs through the provided symbol table and patches 8680 each symbol marked as a file place holder (`C_FILE') to point to the 8681 next file place holder in the list. It also marks each `offset' field 8682 in the list with the offset from the first symbol of the current symbol. 8683 8684 Another function of this procedure is to turn the canonical value 8685 form of BFD into the form used by coff. Internally, BFD expects symbol 8686 values to be offsets from a section base; so a symbol physically at 8687 0x120, but in a section starting at 0x100, would have the value 0x20. 8688 Coff expects symbols to contain their final value, so symbols have 8689 their values changed at this point to reflect their sum with their 8690 owning section. This transformation uses the `output_section' field of 8691 the `asymbol''s `asection' *Note Sections::. 8692 8693 * `coff_mangle_symbols' 8694 This routine runs though the provided symbol table and uses the 8695 offsets generated by the previous pass and the pointers generated when 8696 the symbol table was read in to create the structured hierarchy 8697 required by coff. It changes each pointer to a symbol into the index 8698 into the symbol table of the asymbol. 8699 8700 * `coff_write_symbols' 8701 This routine runs through the symbol table and patches up the 8702 symbols from their internal form into the coff way, calls the bit 8703 twiddlers, and writes out the table to the file. 8704 8705 3.3.2.6 `coff_symbol_type' 8706 .......................... 8707 8708 *Description* 8709 The hidden information for an `asymbol' is described in a 8710 `combined_entry_type': 8711 8712 8713 typedef struct coff_ptr_struct 8714 { 8715 /* Remembers the offset from the first symbol in the file for 8716 this symbol.

write relocations, the back end steps though the canonical 9068 relocation table and create an `internal_reloc'. The symbol index to 9069 use is removed from the `offset' field in the symbol table supplied. 9070 The address comes directly from the sum of the section base address and 9071 the relocation offset; the type is dug directly from the howto field. 9072 Then the `internal_reloc' is swapped into the shape of an 9073 `external_reloc' and written out to disk. 9074 9075 3.3.2.9 Reading linenumbers 9076 ........................... 9077 9078 Creating the linenumber table is done by reading in the entire coff 9079 linenumber table, and creating another table for internal use. 9080 9081 A coff linenumber table is structured so that each function is 9082 marked as having a line number of 0. Each line within the function is 9083 an offset from the first line in the function. The base of the line 9084 number information for the table is stored in the symbol associated 9085 with the function. 9086 9087 Note: The PE format uses line number 0 for a flag indicating a new 9088 source file. 9089 9090 The information is copied from the external to the internal table, 9091 and each symbol which marks a function is marked by pointing its... 9092 9093 How does this work ? 9094 9095 3.3.2.10 Reading relocations 9096 ............................ 9097 9098 Coff relocations are easily transformed into the internal BFD form 9099 (`arelent'). 9100 9101 Reading a coff relocation table is done in the following stages: 9102 9103 * Read the entire coff relocation table into memory. 9104 9105 * Process each relocation in turn; first swap it from the external 9106 to the internal form. 9107 9108 * Turn the symbol referenced in the relocation's symbol index into a 9109 pointer into the canonical symbol table. This table is the same 9110 as the one returned by a call to `bfd_canonicalize_symtab'. The 9111 back end will call that routine and save the result if a 9112 canonicalization hasn't been done. 9113 9114 * The reloc index is turned into a pointer to a howto structure, in 9115 a back end specific way. For instance, the 386 and 960 use the 9116 `r_type' to directly produce an index into a howto table vector; 9117 the 88k subtracts a number from the `r_type' field and creates an 9118 addend field. 9119 9120 9121 File: bfd.info, Node: elf, Next: mmo, Prev: coff, Up: BFD back ends 9122 9123 3.4 ELF backends 9124 ================ 9125 9126 BFD support for ELF formats is being worked on. Currently, the best 9127 supported back ends are for sparc and i386 (running svr4 or Solaris 2). 9128 9129 Documentation of the internals of the support code still needs to be 9130 written. The code is changing quickly enough that we haven't bothered 9131 yet. 9132 9133 9134 File: bfd.info, Node: mmo, Prev: elf, Up: BFD back ends 9135 9136 3.5 mmo backend 9137 =============== 9138 9139 The mmo object format is used exclusively together with Professor 9140 Donald E. Knuth's educational 64-bit processor MMIX. The simulator 9141 `mmix' which is available at 9142 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz' 9143 understands this format. That package also includes a combined 9144 assembler and linker called `mmixal'. The mmo format has no advantages 9145 feature-wise compared to e.g. ELF. It is a simple non-relocatable 9146 object format with no support for archives or debugging information, 9147 except for symbol value information and line numbers (which is not yet 9148 implemented in BFD). See 9149 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more 9150 information about MMIX. The ELF format is used for intermediate object 9151 files in the BFD implementation. 9152 9153 * Menu: 9154 9155 * File layout:: 9156 * Symbol-table:: 9157 * mmo section mapping:: 9158 9159 9160 File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo 9161 9162 3.5.1 File layout 9163 ----------------- 9164 9165 The mmo file contents is not partitioned into named sections as with 9166 e.g. ELF. Memory areas is formed by specifying the location of the 9167 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff' 9168 is executable, so it is used for code (and constants) and the area 9169 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo 9170 section mapping::. 9171 9172 There is provision for specifying "special data" of 65536 different 9173 types. We use type 80 (decimal), arbitrarily chosen the same as the 9174 ELF `e_machine' number for MMIX, filling it with section information 9175 normally found in ELF objects. *Note mmo section mapping::. 9176 9177 Contents is entered as 32-bit words, xor:ed over previous contents, 9178 always zero-initialized. A word that starts with the byte `0x98' forms 9179 a command called a `lopcode', where the next byte distinguished between 9180 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z' 9181 fields, or the `YZ' field (a 16-bit big-endian number), are used for 9182 various purposes different for each lopcode. As documented in 9183 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the 9184 lopcodes are: 9185 9186 `lop_quote' 9187 0x98000001. The next word is contents, regardless of whether it 9188 starts with 0x98 or not. 9189 9190 `lop_loc' 9191 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive, 9192 setting the location for the next data to the next 32-bit word 9193 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally 9194 `Y' is 0 for the text segment and 2 for the data segment. 9195 9196 `lop_skip' 9197 0x9802YYZZ. Increase the current location by `YZ' bytes. 9198 9199 `lop_fixo' 9200 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64 9201 bits into the location pointed to by the next 32-bit (Z = 1) or 9202 64-bit (Z = 2) word, plus Y * 2^56. 9203 9204 `lop_fixr' 9205 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 * 9206 YZ. 9207 9208 `lop_fixrx' 9209 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the 9210 following 32-bit word are used in a manner similar to `YZ' in 9211 lop_fixr: it is xor:ed into the current location minus 4 * L. The 9212 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24 9213 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD). 9214 9215 `lop_file' 9216 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words. 9217 Set the file number to `Y' and the line counter to 0. The next Z 9218 * 4 bytes contain the file name, padded with zeros if the count is 9219 not a multiple of four. The same `Y' may occur multiple times, 9220 but `Z' must be 0 for all but the first occurrence. 9221 9222 `lop_line' 9223 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it 9224 forms the source location for the next 32-bit word. Note that for 9225 each non-lopcode 32-bit word, line numbers are assumed incremented 9226 by one. 9227 9228 `lop_spec' 9229 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode 9230 other than lop_quote forms special data of type `YZ'. *Note mmo 9231 section mapping::. 9232 9233 Other types than 80, (or type 80 with a content that does not 9234 parse) is stored in sections named `.MMIX.spec_data.N' where N is 9235 the `YZ'-type. The flags for such a sections say not to allocate 9236 or load the data. The vma is 0. Contents of multiple occurrences 9237 of special data N is concatenated to the data of the previous 9238 lop_spec Ns. The location in data or code at which the lop_spec 9239 occurred is lost. 9240 9241 `lop_pre' 9242 0x980901ZZ. The first lopcode in a file. The `Z' field forms the 9243 length of header information in 32-bit words, where the first word 9244 tells the time in seconds since `00:00:00 GMT Jan 1 1970'. 9245 9246 `lop_post' 9247 0x980a00ZZ. Z > 32. This lopcode follows after all 9248 content-generating lopcodes in a program. The `Z' field denotes 9249 the value of `rG' at the beginning of the program. The following 9250 256 - Z big-endian 64-bit words are loaded into global registers 9251 `$G' ... `$255'. 9252 9253 `lop_stab' 9254 0x980b0000. The next-to-last lopcode in a program. Must follow 9255 immediately after the lop_post lopcode and its data. After this 9256 lopcode follows all symbols in a compressed format (*note 9257 Symbol-table::). 9258 9259 `lop_end' 9260 0x980cYYZZ. The last lopcode in a program. It must follow the 9261 lop_stab lopcode and its data. The `YZ' field contains the number 9262 of 32-bit words of symbol table information after the preceding 9263 lop_stab lopcode. 9264 9265 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and 9266 `lop_fixo' are not generated by BFD, but are handled. They are 9267 generated by `mmixal'. 9268 9269 This trivial one-label, one-instruction file: 9270 9271 :Main TRAP 1,2,3 9272 9273 can be represented this way in mmo: 9274 9275 0x98090101 - lop_pre, one 32-bit word with timestamp. 9276 <timestamp> 9277 0x98010002 - lop_loc, text segment, using a 64-bit address. 9278 Note that mmixal does not emit this for the file above. 9279 0x00000000 - Address, high 32 bits. 9280 0x00000000 - Address, low 32 bits. 9281 0x98060002 - lop_file, 2 32-bit words for file-name. 9282 0x74657374 - "test" 9283 0x2e730000 - ".s\0\0" 9284 0x98070001 - lop_line, line 1. 9285 0x00010203 - TRAP 1,2,3 9286 0x980a00ff - lop_post, setting $255 to 0. 9287 0x00000000 9288 0x00000000 9289 0x980b0000 - lop_stab for ":Main" = 0, serial 1. 9290 0x203a4040 *Note Symbol-table::. 9291 0x10404020 9292 0x4d206120 9293 0x69016e00 9294 0x81000000 9295 0x980c0005 - lop_end; symbol table contained five 32-bit words. 9296 9297 9298 File: bfd.info, Node: Symbol-table, Next: mmo section mapping, Prev: File layout, Up: mmo 9299 9300 3.5.2 Symbol table format 9301 ------------------------- 9302 9303 From mmixal.w (or really, the generated mmixal.tex) in 9304 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'): 9305 "Symbols are stored and retrieved by means of a `ternary search trie', 9306 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on 9307 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C' 9308 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores 9309 a character, and there are branches to subtries for the cases where a 9310 given character is less than, equal to, or greater than the character 9311 in the trie. There also is a pointer to a symbol table entry if a 9312 symbol ends at the current node." 9313 9314 So it's a tree encoded as a stream of bytes. The stream of bytes 9315 acts on a single virtual global symbol, adding and removing characters 9316 and signalling complete symbol points. Here, we read the stream and 9317 create symbols at the completion points. 9318 9319 First, there's a control byte `m'. If any of the listed bits in `m' 9320 is nonzero, we execute what stands at the right, in the listed order: 9321 9322 (MMO3_LEFT) 9323 0x40 - Traverse left trie. 9324 (Read a new command byte and recurse.) 9325 9326 (MMO3_SYMBITS) 9327 0x2f - Read the next byte as a character and store it in the 9328 current character position; increment character position. 9329 Test the bits of `m': 9330 9331 (MMO3_WCHAR) 9332 0x80 - The character is 16-bit (so read another byte, 9333 merge into current character. 9334 9335 (MMO3_TYPEBITS) 9336 0xf - We have a complete symbol; parse the type, value 9337 and serial number and do what should be done 9338 with a symbol. The type and length information 9339 is in j = (m & 0xf). 9340 9341 (MMO3_REGQUAL_BITS) 9342 j == 0xf: A register variable. The following 9343 byte tells which register. 9344 j <= 8: An absolute symbol. Read j bytes as the 9345 big-endian number the symbol equals. 9346 A j = 2 with two zero bytes denotes an 9347 unknown symbol. 9348 j > 8: As with j <= 8, but add (0x20 << 56) 9349 to the value in the following j - 8 9350 bytes. 9351 9352 Then comes the serial number, as a variant of 9353 uleb128, but better named ubeb128: 9354 Read bytes and shift the previous value left 7 9355 (multiply by 128). Add in the new byte, repeat 9356 until a byte has bit 7 set. The serial number 9357 is the computed value minus 128. 9358 9359 (MMO3_MIDDLE) 9360 0x20 - Traverse middle trie. (Read a new command byte 9361 and recurse.) Decrement character position. 9362 9363 (MMO3_RIGHT) 9364 0x10 - Traverse right trie. (Read a new command byte and 9365 recurse.) 9366 9367 Let's look again at the `lop_stab' for the trivial file (*note File 9368 layout::). 9369 9370 0x980b0000 - lop_stab for ":Main" = 0, serial 1. 9371 0x203a4040 9372 0x10404020 9373 0x4d206120 9374 0x69016e00 9375 0x81000000 9376 9377 This forms the trivial trie (note that the path between ":" and "M" 9378 is redundant): 9379 9380 203a ":" 9381 40 / 9382 40 / 9383 10 \ 9384 40 / 9385 40 / 9386 204d "M" 9387 2061 "a" 9388 2069 "i" 9389 016e "n" is the last character in a full symbol, and 9390 with a value represented in one byte. 9391 00 The value is 0. 9392 81 The serial number is 1. 9393 9394 9395 File: bfd.info, Node: mmo section mapping, Prev: Symbol-table, Up: mmo 9396 9397 3.5.3 mmo section mapping 9398 ------------------------- 9399 9400 The implementation in BFD uses special data type 80 (decimal) to 9401 encapsulate and describe named sections, containing e.g. debug 9402 information. If needed, any datum in the encapsulation will be quoted 9403 using lop_quote. First comes a 32-bit word holding the number of 9404 32-bit words containing the zero-terminated zero-padded segment name. 9405 After the name there's a 32-bit word holding flags describing the 9406 section type. Then comes a 64-bit big-endian word with the section 9407 length (in bytes), then another with the section start address. 9408 Depending on the type of section, the contents might follow, 9409 zero-padded to 32-bit boundary. For a loadable section (such as data 9410 or code), the contents might follow at some later point, not 9411 necessarily immediately, as a lop_loc with the same start address as in 9412 the section description, followed by the contents. This in effect 9413 forms a descriptor that must be emitted before the actual contents. 9414 Sections described this way must not overlap. 9415 9416 For areas that don't have such descriptors, synthetic sections are 9417 formed by BFD. Consecutive contents in the two memory areas 9418 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are 9419 entered in sections named `.text' and `.data' respectively. If an area 9420 is not otherwise described, but would together with a neighboring lower 9421 area be less than `0x40000000' bytes long, it is joined with the lower 9422 area and the gap is zero-filled. For other cases, a new section is 9423 formed, named `.MMIX.sec.N'. Here, N is a number, a running count 9424 through the mmo file, starting at 0. 9425 9426 A loadable section specified as: 9427 9428 .section secname,"ax" 9429 TETRA 1,2,3,4,-1,-2009 9430 BYTE 80 9431 9432 and linked to address `0x4', is represented by the sequence: 9433 9434 0x98080050 - lop_spec 80 9435 0x00000002 - two 32-bit words for the section name 9436 0x7365636e - "secn" 9437 0x616d6500 - "ame\0" 9438 0x00000033 - flags CODE, READONLY, LOAD, ALLOC 9439 0x00000000 - high 32 bits of section length 9440 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits 9441 0x00000000 - high 32 bits of section address 9442 0x00000004 - section address is 4 9443 0x98010002 - 64 bits with address of following data 9444 0x00000000 - high 32 bits of address 9445 0x00000004 - low 32 bits: data starts at address 4 9446 0x00000001 - 1 9447 0x00000002 - 2 9448 0x00000003 - 3 9449 0x00000004 - 4 9450 0xffffffff - -1 9451 0xfffff827 - -2009 9452 0x50000000 - 80 as a byte, padded with zeros. 9453 9454 Note that the lop_spec wrapping does not include the section 9455 contents.

A copy made in an 9565 otherwise Transparent file format whose markup, or absence of 9566 markup, has been arranged to thwart or discourage subsequent 9567 modification by readers is not Transparent. An image format is 9568 not Transparent if used for any substantial amount of text. A 9569 copy that is not "Transparent" is called "Opaque". 9570 9571 Examples of suitable formats for Transparent copies include plain 9572 ASCII without markup, Texinfo input format, LaTeX input format, 9573 SGML or XML using a publicly available DTD, and 9574 standard-conforming simple HTML, PostScript or PDF designed for 9575 human modification. Examples of transparent image formats include 9576 PNG, XCF and JPG. Opaque formats include proprietary formats that 9577 can be read and edited only by proprietary word processors, SGML or 9578 XML for which the DTD and/or processing tools are not generally 9579 available, and the machine-generated HTML, PostScript or PDF 9580 produced by some word processors for output purposes only. 9581 9582 The "Title Page" means, for a printed book, the title page itself, 9583 plus such following pages as are needed to hold, legibly, the 9584 material this License requires to appear in the title page. For 9585 works in formats which do not have any title page as such, "Title 9586 Page" means the text near the most prominent appearance of the 9587 work's title, preceding the beginning of the body of the text. 9588 9589 The "publisher" means any person or entity that distributes copies 9590 of the Document to the public. 9591 9592 A section "Entitled XYZ" means a named subunit of the Document 9593 whose title either is precisely XYZ or contains XYZ in parentheses 9594 following text that translates XYZ in another language. (Here XYZ 9595 stands for a specific section name mentioned below, such as 9596 "Acknowledgements", "Dedications", "Endorsements", or "History".) 9597 To "Preserve the Title" of such a section when you modify the 9598 Document means that it remains a section "Entitled XYZ" according 9599 to this definition. 9600 9601 The Document may include Warranty Disclaimers next to the notice 9602 which states that this License applies to the Document. These 9603 Warranty Disclaimers are considered to be included by reference in 9604 this License, but only as regards disclaiming warranties: any other 9605 implication that these Warranty Disclaimers may have is void and 9606 has no effect on the meaning of this License. 9607 9608 2. VERBATIM COPYING 9609 9610 You may copy and distribute the Document in any medium, either 9611 commercially or noncommercially, provided that this License, the 9612 copyright notices, and the license notice saying this License 9613 applies to the Document are reproduced in all copies, and that you 9614 add no other conditions whatsoever to those of this License. You 9615 may not use technical measures to obstruct or control the reading 9616 or further copying of the copies you make or distribute. However, 9617 you may accept compensation in exchange for copies. If you 9618 distribute a large enough number of copies you must also follow 9619 the conditions in section 3. 9620 9621 You may also lend copies, under the same conditions stated above, 9622 and you may publicly display copies. 9623 9624 3. COPYING IN QUANTITY 9625 9626 If you publish printed copies (or copies in media that commonly 9627 have printed covers) of the Document, numbering more than 100, and 9628 the Document's license notice requires Cover Texts, you must 9629 enclose the copies in covers that carry, clearly and legibly, all 9630 these Cover Texts: Front-Cover Texts on the front cover, and 9631 Back-Cover Texts on the back cover. Both covers must also clearly 9632 and legibly identify you as the publisher of these copies. The 9633 front cover must present the full title with all words of the 9634 title equally prominent and visible. You may add other material 9635 on the covers in addition. Copying with changes limited to the 9636 covers, as long as they preserve the title of the Document and 9637 satisfy these conditions, can be treated as verbatim copying in 9638 other respects. 9639 9640 If the required texts for either cover are too voluminous to fit 9641 legibly, you should put the first ones listed (as many as fit 9642 reasonably) on the actual cover, and continue the rest onto 9643 adjacent pages. 9644 9645 If you publish or distribute Opaque copies of the Document 9646 numbering more than 100, you must either include a 9647 machine-readable Transparent copy along with each Opaque copy, or 9648 state in or with each Opaque copy a computer-network location from 9649 which the general network-using public has access to download 9650 using public-standard network protocols a complete Transparent 9651 copy of the Document, free of added material. If you use the 9652 latter option, you must take reasonably prudent steps, when you 9653 begin distribution of Opaque copies in quantity, to ensure that 9654 this Transparent copy will remain thus accessible at the stated 9655 location until at least one year after the last time you 9656 distribute an Opaque copy (directly or through your agents or 9657 retailers) of that edition to the public. 9658 9659 It is requested, but not required, that you contact the authors of 9660 the Document well before redistributing any large number of 9661 copies, to give them a chance to provide you with an updated 9662 version of the Document. 9663 9664 4. MODIFICATIONS 9665 9666 You may copy and distribute a Modified Version of the Document 9667 under the conditions of sections 2 and 3 above, provided that you 9668 release the Modified Version under precisely this License, with 9669 the Modified Version filling the role of the Document, thus 9670 licensing distribution and modification of the Modified Version to 9671 whoever possesses a copy of it. In addition, you must do these 9672 things in the Modified Version: 9673 9674 A. Use in the Title Page (and on the covers, if any) a title 9675 distinct from that of the Document, and from those of 9676 previous versions (which should, if there were any, be listed 9677 in the History section of the Document). You may use the 9678 same title as a previous version if the original publisher of 9679 that version gives permission. 9680 9681 B. List on the Title Page, as authors, one or more persons or 9682 entities responsible for authorship of the modifications in 9683 the Modified Version, together with at least five of the 9684 principal authors of the Document (all of its principal 9685 authors, if it has fewer than five), unless they release you 9686 from this requirement. 9687 9688 C. State on the Title page the name of the publisher of the 9689 Modified Version, as the publisher. 9690 9691 D. Preserve all the copyright notices of the Document. 9692 9693 E. Add an appropriate copyright notice for your modifications 9694 adjacent to the other copyright notices. 9695 9696 F. Include, immediately after the copyright notices, a license 9697 notice giving the public permission to use the Modified 9698 Version under the terms of this License, in the form shown in 9699 the Addendum below. 9700 9701 G. Preserve in that license notice the full lists of Invariant 9702 Sections and required Cover Texts given in the Document's 9703 license notice. 9704 9705 H. Include an unaltered copy of this License. 9706 9707 I. Preserve the section Entitled "History", Preserve its Title, 9708 and add to it an item stating at least the title, year, new 9709 authors, and publisher of the Modified Version as given on 9710 the Title Page. If there is no section Entitled "History" in 9711 the Document, create one stating the title, year, authors, 9712 and publisher of the Document as given on its Title Page, 9713 then add an item describing the Modified Version as stated in 9714 the previous sentence. 9715 9716 J. Preserve the network location, if any, given in the Document 9717 for public access to a Transparent copy of the Document, and 9718 likewise the network locations given in the Document for 9719 previous versions it was based on. These may be placed in 9720 the "History" section. You may omit a network location for a 9721 work that was published at least four years before the 9722 Document itself, or if the original publisher of the version 9723 it refers to gives permission. 9724 9725 K. For any section Entitled "Acknowledgements" or "Dedications", 9726 Preserve the Title of the section, and preserve in the 9727 section all the substance and tone of each of the contributor 9728 acknowledgements and/or dedications given therein. 9729 9730 L. Preserve all the Invariant Sections of the Document, 9731 unaltered in their text and in their titles. Section numbers 9732 or the equivalent are not considered part of the section 9733 titles. 9734 9735 M. Delete any section Entitled "Endorsements". Such a section 9736 may not be included in the Modified Version. 9737 9738 N. Do not retitle any existing section to be Entitled 9739 "Endorsements" or to conflict in title with any Invariant 9740 Section. 9741 9742 O. Preserve any Warranty Disclaimers. 9743 9744 If the Modified Version includes new front-matter sections or 9745 appendices that qualify as Secondary Sections and contain no 9746 material copied from the Document, you may at your option 9747 designate some or all of these sections as invariant. To do this, 9748 add their titles to the list of Invariant Sections in the Modified 9749 Version's license notice. These titles must be distinct from any 9750 other section titles. 9751 9752 You may add a section Entitled "Endorsements", provided it contains 9753 nothing but endorsements of your Modified Version by various 9754 parties--for example, statements of peer review or that the text 9755 has been approved by an organization as the authoritative 9756 definition of a standard. 9757 9758 You may add a passage of up to five words as a Front-Cover Text, 9759 and a passage of up to 25 words as a Back-Cover Text, to the end 9760 of the list of Cover Texts in the Modified Version. Only one 9761 passage of Front-Cover Text and one of Back-Cover Text may be 9762 added by (or through arrangements made by) any one entity. If the 9763 Document already includes a cover text for the same cover, 9764 previously added by you or by arrangement made by the same entity 9765 you are acting on behalf of, you may not add another; but you may 9766 replace the old one, on explicit permission from the previous 9767 publisher that added the old one. 9768 9769 The author(s) and publisher(s) of the Document do not by this 9770 License give permission to use their names for publicity for or to 9771 assert or imply endorsement of any Modified Version. 9772 9773 5. COMBINING DOCUMENTS 9774 9775 You may combine the Document with other documents released under 9776 this License, under the terms defined in section 4 above for 9777 modified versions, provided that you include in the combination 9778 all of the Invariant Sections of all of the original documents, 9779 unmodified, and list them all as Invariant Sections of your 9780 combined work in its license notice, and that you preserve all 9781 their Warranty Disclaimers. 9782 9783 The combined work need only contain one copy of this License, and 9784 multiple identical Invariant Sections may be replaced with a single 9785 copy. If there are multiple Invariant Sections with the same name 9786 but different contents, make the title of each such section unique 9787 by adding at the end of it, in parentheses, the name of the 9788 original author or publisher of that section if known, or else a 9789 unique number. Make the same adjustment to the section titles in 9790 the list of Invariant Sections in the license notice of the 9791 combined work. 9792 9793 In the combination, you must combine any sections Entitled 9794 "History" in the various original documents, forming one section 9795 Entitled "History"; likewise combine any sections Entitled 9796 "Acknowledgements", and any sections Entitled "Dedications". You 9797 must delete all sections Entitled "Endorsements." 9798 9799 6. COLLECTIONS OF DOCUMENTS 9800 9801 You may make a collection consisting of the Document and other 9802 documents released under this License, and replace the individual 9803 copies of this License in the various documents with a single copy 9804 that is included in the collection, provided that you follow the 9805 rules of this License for verbatim copying of each of the 9806 documents in all other respects. 9807 9808 You may extract a single document from such a collection, and 9809 distribute it individually under this License, provided you insert 9810 a copy of this License into the extracted document, and follow 9811 this License in all other respects regarding verbatim copying of 9812 that document. 9813 9814 7. AGGREGATION WITH INDEPENDENT WORKS 9815 9816 A compilation of the Document or its derivatives with other 9817 separate and independent documents or works, in or on a volume of 9818 a storage or distribution medium, is called an "aggregate" if the 9819 copyright resulting from the compilation is not used to limit the 9820 legal rights of the compilation's users beyond what the individual 9821 works permit. When the Document is included in an aggregate, this 9822 License does not apply to the other works in the aggregate which 9823 are not themselves derivative works of the Document. 9824 9825 If the Cover Text requirement of section 3 is applicable to these 9826 copies of the Document, then if the Document is less than one half 9827 of the entire aggregate, the Document's Cover Texts may be placed 9828 on covers that bracket the Document within the aggregate, or the 9829 electronic equivalent of covers if the Document is in electronic 9830 form. Otherwise they must appear on printed covers that bracket 9831 the whole aggregate. 9832 9833 8. TRANSLATION 9834 9835 Translation is considered a kind of modification, so you may 9836 distribute translations of the Document under the terms of section 9837 4. Replacing Invariant Sections with translations requires special 9838 permission from their copyright holders, but you may include 9839 translations of some or all Invariant Sections in addition to the 9840 original versions of these Invariant Sections. You may include a 9841 translation of this License, and all the license notices in the 9842 Document, and any Warranty Disclaimers, provided that you also 9843 include the original English version of this License and the 9844 original versions of those notices and disclaimers. In case of a 9845 disagreement between the translation and the original version of 9846 this License or a notice or disclaimer, the original version will 9847 prevail. 9848 9849 If a section in the Document is Entitled "Acknowledgements", 9850 "Dedications", or "History", the requirement (section 4) to 9851 Preserve its Title (section 1) will typically require changing the 9852 actual title. 9853 9854 9. TERMINATION 9855 9856 You may not copy, modify, sublicense, or distribute the Document 9857 except as expressly provided under this License. Any attempt 9858 otherwise to copy, modify, sublicense, or distribute it is void, 9859 and will automatically terminate your rights under this License. 9860 9861 However, if you cease all violation of this License, then your 9862 license from a particular copyright holder is reinstated (a) 9863 provisionally, unless and until the copyright holder explicitly 9864 and finally terminates your license, and (b) permanently, if the 9865 copyright holder fails to notify you of the violation by some 9866 reasonable means prior to 60 days after the cessation. 9867 9868 Moreover, your license from a particular copyright holder is 9869 reinstated permanently if the copyright holder notifies you of the 9870 violation by some reasonable means, this is the first time you have 9871 received notice of violation of this License (for any work) from 9872 that copyright holder, and you cure the violation prior to 30 days 9873 after your receipt of the notice. 9874 9875 Termination of your rights under this section does not terminate 9876 the licenses of parties who have received copies or rights from 9877 you under this License. If your rights have been terminated and 9878 not permanently reinstated, receipt of a copy of some or all of 9879 the same material does not give you any rights to use it. 9880 9881 10. FUTURE REVISIONS OF THIS LICENSE 9882 9883 The Free Software Foundation may publish new, revised versions of 9884 the GNU Free Documentation License from time to time. Such new 9885 versions will be similar in spirit to the present version, but may 9886 differ in detail to address new problems or concerns. See 9887 `http://www.gnu.org/copyleft/'. 9888 9889 Each version of the License is given a distinguishing version 9890 number. If the Document specifies that a particular numbered 9891 version of this License "or any later version" applies to it, you 9892 have the option of following the terms and conditions either of 9893 that specified version or of any later version that has been 9894 published (not as a draft) by the Free Software Foundation. If 9895 the Document does not specify a version number of this License, 9896 you may choose any version ever published (not as a draft) by the 9897 Free Software Foundation. If the Document specifies that a proxy 9898 can decide which future versions of this License can be used, that 9899 proxy's public statement of acceptance of a version permanently 9900 authorizes you to choose that version for the Document. 9901 9902 11. RELICENSING 9903 9904 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any 9905 World Wide Web server that publishes copyrightable works and also 9906 provides prominent facilities for anybody to edit those works. A 9907 public wiki that anybody can edit is an example of such a server. 9908 A "Massive Multiauthor Collaboration" (or "MMC") contained in the 9909 site means any set of copyrightable works thus published on the MMC 9910 site. 9911 9912 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 9913 license published by Creative Commons Corporation, a not-for-profit 9914 corporation with a principal place of business in San Francisco, 9915 California, as well as future copyleft versions of that license 9916 published by that same organization. 9917 9918 "Incorporate" means to publish or republish a Document, in whole or 9919 in part, as part of another Document. 9920 9921 An MMC is "eligible for relicensing" if it is licensed under this 9922 License, and if all works that were first published under this 9923 License somewhere other than this MMC, and subsequently 9924 incorporated in whole or in part into the MMC, (1) had no cover 9925 texts or invariant sections, and (2) were thus incorporated prior 9926 to November 1, 2008. 9927 9928 The operator of an MMC Site may republish an MMC contained in the 9929 site under CC-BY-SA on the same site at any time before August 1, 9930 2009, provided the MMC is eligible for relicensing. 9931 9932 9933 ADDENDUM: How to use this License for your documents 9934 ==================================================== 9935 9936 To use this License in a document you have written, include a copy of 9937 the License in the document and put the following copyright and license 9938 notices just after the title page: 9939 9940 Copyright (C) YEAR YOUR NAME. 9941 Permission is granted to copy, distribute and/or modify this document 9942 under the terms of the GNU Free Documentation License, Version 1.3 9943 or any later version published by the Free Software Foundation; 9944 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover 9945 Texts. A copy of the license is included in the section entitled ``GNU 9946 Free Documentation License''. 9947 9948 If you have Invariant Sections, Front-Cover Texts and Back-Cover 9949 Texts, replace the "with...Texts." line with this: 9950 9951 with the Invariant Sections being LIST THEIR TITLES, with 9952 the Front-Cover Texts being LIST, and with the Back-Cover Texts 9953 being LIST. 9954 9955 If you have Invariant Sections without Cover Texts, or some other 9956 combination of the three, merge those two alternatives to suit the 9957 situation. 9958 9959 If your document contains nontrivial examples of program code, we 9960 recommend releasing these examples in parallel under your choice of 9961 free software license, such as the GNU General Public License, to 9962 permit their use in free software. 9963 9964 9965 File: bfd.info, Node: BFD Index, Prev: GNU Free Documentation License, Up: Top 9966 9967 BFD Index 9968 ********* 9969 9970 [index] 9971 * Menu: 9972 9973 * _bfd_final_link_relocate: Relocating the section contents. 9974 (line 22) 9975 * _bfd_generic_link_add_archive_symbols: Adding symbols from an archive. 9976 (line 15) 9977 * _bfd_generic_link_add_one_symbol: Adding symbols from an object file. 9978 (line 19) 9979 * _bfd_generic_make_empty_symbol: symbol handling functions. 9980 (line 92) 9981 * _bfd_link_add_symbols in target vector: Adding Symbols to the Hash Table. 9982 (line 6) 9983 * _bfd_link_final_link in target vector: Performing the Final Link. 9984 (line 6) 9985 * _bfd_link_hash_table_create in target vector: Creating a Linker Hash Table. 9986 (line 6) 9987 * _bfd_relocate_contents: Relocating the section contents. 9988 (line 22) 9989 * aout_SIZE_machine_type: aout.
