1 2 - add support for prof file format so that prof files can be displayed 3 at the line-level (this is useful for the uprofile tool under DEC's 4 OSF/1) 5 - take a hard look at --file-ordering (broken) and --function-ordering 6 7 + documentation 8 + optimize bfd_find_nearest_line_num() (or replace by different interface) 9 + cleanup _bfd_ecoff_find_nearest_line_num() fixes & description 10 + ensure "cc -pg" produces good files under OSF/1 v3.0 11 + make sure gprof works together with OSF/1 v3.0's profiling libraries 12 + implement symtab_parse(); modify sym_lookup() to consider addr_high 13 + change gprof.c to collect lists, then invoke symtab_parse() for 14 each list 15 + Questions: 16 o is -c (--static-call-graph) useful at all? i can't see 17 how; if it were deleted, gprof would be completely machine 18 independent => yup, it is 19 o are (long) option names appropriate? 20 o -k (--exclude-arc) cannot be implemented with getopt(); 21 is new syntax (-k from/to) acceptable? If not, how to 22 fix it? 23 o in the FSF output, the call-graph index now prints 24 the filename of static functions in parentheses; e.g., 25 static function foo() that is defined in file bar.c 26 would be printed as: 27 28 [4] foo (bar.c) 29 30 is this acceptable? should it be done only optionally? 31 o symbols with addresses that map back to a different 32 name are suppressed (happens with labels, for example); 33 is this acceptable? should it be done only optionally? 34 + generalize to allow arbitrary histograms (not just time histograms) 35 + basic-block information currently replaces all symbols created from 36 the core because of an ugly ordering conflict---for now, the current 37 solution works, but something cleaner is desirable ==> cleaned up, 38 but it's slower now 39 + convert to very new file format (back to trivial format, that is :) 40 + replace "dummy.h" for Alpha (if there is any use to it) 41 + add support for execution time profiling at a basic-block level 42 + fix filename-off-by-one bug for Alpha (see ~/tmp/d.[ch])---no longer 43 relevant 44 + "-pg -a" doesn't work as expected because mcleanup() will overwrite 45 the file generated by __bb_exit_func() (or vice versa) 46 + first basic-block of fac() seems to get credited to last basic-block 47 of previous function => bug in basic_blocks.c 48 + flat profile should provide automatic scaling for per-call times because 49 otherwise they'll always be zero on a fast machine with tons of small 50 functions 51 + make "-a" imply to retain line number info (without actually generating 52 the debugging information (unless -g is specified)---no, this is a 53 bad idea, because it is not clear what level of debugging info should 54 be requested (e.g., -g vs. -g3); leaving it up to the user seems best 55 + add long options support (or at least use getopt instead of ad-hoc 56 implementation) 57 + split into files according to abstract objects that are manipulated 58 + replace sccsid by rcsid & add "end of ..." to every .c file 59 + use DBG() everywhere 60 + fix spacing (" ," -> "," etc.) 61 + use DEFUNs everywhere 62 + make compile cleanly with -Wall 63 + "gcc -pg -O2" doesn't work on tecc.c unless -fno-omit-frame-pointer is 64 specified; find out why 65 + make things portable (prototypes, const, etc.) 66 + if NEW_GMON_OUT is not defined, have a flag that will allow to 67 read new gmon.out style files. The idea being that everyone 68 will use the new format for basic-block style profiling but 69 the old format for regular gpprofiling 70 72 Copyright (C) 2012-2014 Free Software Foundation, Inc. 73 74 Copying and distribution of this file, with or without modification, 75 are permitted in any medium without royalty provided the copyright 76 notice and this notice are preserved. 77
