527 is a static label Ltext_something that aliases the global
530 * hist.c (hist_print): auto-scaling is now in effect for FSF-style
531 output only; also, auto-scaling is now performed based on
532 per-call, rather than total execution time, which is what it was
535 * gprof.h (File_Format): new type.
537 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
538 sync with Cygnus version numbers though...
540 (long_options): renamed --gmon-info to --file-info, --width added,
541 renamed --old-file-format to --file-format
542 (main): dito; also added support to read prof files, but as
543 mon_out_read() is not implemented, it's #ifdef'd out for now
545 (usage): update to reflect new options.
547 * gmon_io.c: replaced "old_file_format" by more general
550 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
552 * core.c (core_sym_class): added back check for __gnu_compiled and
553 ___gnu_compiled for the benefit of systems without
554 bfd_find_nearest_line() support
556 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
557 with section-relative addresses
559 (core_create_function_syms): get_src_info() calls are currently
560 enabled for OSF/1 only. It appears to work allright for SunOS
561 4.1.x as well, but on SPARCs it gets painfully slow with the
562 current implementation of aout_32_find_nearest_line();
563 unfortunately, this means that static functions will not have their
564 filename printed in the call-graph function index; line-level
565 profiling should still work, but requires some patience
567 * cg_print.c (cg_print_index): sanitised printing of index when
568 using FSF-style output; in particular, output width is now controlled
569 via option --width and the function tries hard to keep columns
570 aligned even in the presence of (occasional) long names
572 * NOTES: a first shot at updating the documentation.
574 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
576 * core.c (core_create_function_syms): fixed computation of min_vma
579 * *.c: removed rcsid.
581 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
583 * Lots of changes from David Mosberger-Tang:
585 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
587 * gprof.c (main): put parentheses around & within &&.
589 * basic_blocks.c (bb_read_rec): print warning message (once) when
590 ignoring basic-block execution counts.
592 * source.c (source_file_lookup_name): corrected second argument to
595 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
596 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
598 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
599 supported both for old and new (versioned) gmon.out files. Old
600 files are identified as version 0.
602 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
603 long (instead of 4) because that is what OSF/1 v3.0 uses.
605 * core.c: minor fixes and debugging info changes.
607 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
609 * core.c (core_init): if .text cannot be found, try $CODE$ (the
610 name of the text-section under HP-UX).
612 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
613 points one past the last sampling bin, so hist_scale should be
614 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
617 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
620 * configure.in: added alpha-*-*) for per-target config.
622 * alpha.c, alpha.h: created.
624 * gprof.c (default_excluded_list): <locore>, <hicore> added.
626 * core.c (core_create_function_syms, core_create_line_syms):
627 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
628 all addresses outside the text-space. Thus, sym_lookup(&symtab,
629 addr) continues to guarantee not to return 0 on any address. It
630 also avoids incorrectly crediting the first/last symbol in the
633 * core.c (core_create_line_syms): always create function symbols
634 first, then merge in line symbols; this is so that if parts of the
635 program were compiled without -g, function-level symbols are
638 * utils.c (print_name_only): support for print_path added.
640 * symtab.c (cmp_addr): also use is_func flag in comparison.
641 (symtab_finalize): return immediately when table empty; now
642 more careful about getting rid of the right duplicate symbol.
644 * sparc.c (find_call): many fixes---this function was rather
645 botched in binutils-2.4 already; it should work again.
647 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
648 not good to rely on get_src_info() to return distinct string
651 * search_list.c (search_list_append): added cast for xmalloc().
653 * hist.c: added explicit initialization to some of the global
654 variables; fixed SItab (scales were off by a factor of 10).
656 * hist.h: include of bfd.h added.
658 * gprof.c, gprof.h (print_path): added.
660 * gprof.h (MAX): fixed.
662 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
664 * gmon_io.c: added some casts to (long) so we can always print as %lx
666 * core.c (core_get_text_space): fixed to make it work.
668 * cg_print.c (cg_print_index): added support for print_path option.
670 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
672 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
673 as some compilers complain (e.g., DEC's OSF/1 compiler)
675 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
676 symtab.c: calls to memset() had 2nd and 3rd args reversed.
678 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
680 * gprof.c: added "_mcount" to default_excluded_list.
681 (main): if output_style==0 and there is either a histogram or a
682 call-graph, always generate flat and call-graph, no matter what
683 line_granularity is set to.
685 * source.c (source_file_lookup_name): if searching for sf->name
686 fails, try again with filename obtained after stripping off any
687 partial path from sf->name.
689 * gprof.h (SRCDEBUG): added.
691 * search_list.c (search_list_append): directories were added in wrong
694 * reimplemented selection mechanism from ground up; it is now possible
695 to accurately control what gets included/excluded in each of the
696 output styles; a "symbol-specification" (spec) is the basic means
697 to select a set of symbols; a spec has the syntax:
699 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
702 any of the terminal symbols can be empty, in which case they
703 match anything (wildcards). NAME is interpreted as a FILENAME
704 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
705 with a digit, and as FUNCNAME otherwise.
707 For example, to get a call-graph display that ignores arcs
708 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
709 show only arcs into bar() (no matter what the caller),
710 you'd say "--graph=/bar"; and to get a call-graph without
711 any arc info, you'd say "--graph=/"; similarly, to
712 get a flat profile without mcount, you'd say "--no-flat=mcount"
713 and to get a flat profile that shows includes all functions
714 you'd say "--flat=""" (i.e., an empty spec)
716 * hist.c (hist_print): top_time wasn't initialized to 0.0.
718 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
720 * gmon_out.h: all headers now declared in terms of characters
721 to avoid getting into trouble with different compilers introducing
722 different amount of padding; the code already accessed the fields
723 through bfd functions, so that didn't have to change.
725 * hist.c (hist_read_rec, hist_write_rec): added support for
726 collection pc histograms measuring quantities other than time;
727 the histogram header now includes a field that specifies the
728 dimension of the quantity measured by the histogram bins
729 (normally, this is "seconds", but other meaningful dimensions
730 include such things as "I-cache misses", "instruction issue stalls"
731 etc.); there is also a field to specify a one-character
732 abbreviation for the dimension; in the case of time, this would
733 be 's'; in most other cases it probably would be '1' (not a physical
736 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
738 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
739 has become old_file_version; gmon_io.c now always supports old-style
740 gmon.out files; it first tries to read gmon.out as a new version
741 file, if that fails, it tries to read it in the old format;
742 although not very likely, it is possible for gprof to mistake an
743 old-style file as a new one (the first 4 bytes would have to
744 be "gmon"---including the trailing '\0'); in that case, it is
745 necessary to specify --old-file-version
747 * gprof.h: removed dependency on SYSV; the code now always uses
748 strrchr(), memset(), and memcpy() and does not include either
749 of string.h or strings.h; this should make gprof compile on
750 any (Unix) system without configuration (per suggestion of
753 * gprof.c (usage): fixed location of --new-file-format option.
755 * cg_arcs.c (propagate_flags): fixed typo in declaration.
757 * flat_bl.m: removed formfeed at end of file; the form-feed
758 is now printed cg_print.c only when necessary.
760 * major rewrite of gprof---too many changes to mention all of
763 + -l now requests profiling at the line level (as opposed
764 to function level); in this mode, gprof creates a "symbol"
765 (aka name-list entry) for each line of source code, instead
768 + support for a new gmon.out file format; the new format
769 consists of a header with a magic and a version number,
770 followed by a sequence of profile data; profile data
771 can any of: (a) PC histogram, (b) call-graph arcs, or
772 (c) basic-block execution counts; the version number makes
773 it possible to extend gmon.out in a backwards compatible
776 + support for tcov style annotated output: if the gmon.out file
777 contains basic-block execution counts, the user can request
778 the generation of annotated source files, much like Sun's
783 + new scheme to suppress symbols that aren't function names
784 (e.g., avoids mistaking a goto label as a function)
786 + reorganized source code to make it more managable; as a
787 side effect, gprof now compiles cleanly with "gcc -Wall"
789 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
791 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
792 final cross-check to determine whether a static symbol should be
793 considered as a function-name.
795 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
797 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
798 stdin; this is useful if you wanna keep gmon.out files compressed;
799 this way you can "gzcat" the compressed file into gprof.
801 * gprof.c: flag_min_count now initialized with 1 instead of 0.
803 * basic_blocks.c (bb_annotate_source): added support for creating
804 .tcov files when option flag_annotate_make_files is TRUE.
805 (annotate_with_count): all counts less than the minimum count
806 specified by -m are now annotated with hash-marks.
808 * gprof.c (main): -A is now followed by a string of option chars.
810 * basic_blocks.c (annotate_with_count): replaced b->count with
813 * source.c: flag_annotate_source replaced by source_lock_map.
815 * source.h: source_lock_map added.
817 * gprof.c (main): new command-line syntax: -S simply specifies
818 which source-files user is interested in; -A requests annotated
819 source files and -AA requests that all lines in a source file
822 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
824 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
826 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
827 so s_lowpc etc. get declared.
829 * arcs.h (doarcs): created.
831 * arcs.c: reordered static functions such that they get defined
834 * gprof.c (main): added options:
835 -A: request annotation of all source lines (with -S)
836 -m: minimum execution count (with default basic-block display)
837 -N: force new file format (only if BSD_COMPATIBLE is defined)
838 -S: annotate source file
839 -t: set table length (with -S)
841 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
844 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
846 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
847 on the fact being able to store a long in a double without loss of
848 precision; this does not hold on machines with 64 bit longs and 64
851 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
853 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
854 greater than 0.0. Suggested by Harold Assink
855 <carlo@sg.tn.tudelft.nl>.
857 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
859 * printgprof.c (printprof): Use free, not cfree.
860 (printgprof, printindex): Ditto.
862 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
864 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
865 decls extern to keep native HP compiler quiet.
867 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
869 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
870 __gnu_compiled, for the benefit of systems which add a leading
873 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
875 * configure.in: Change i386-*-* to i[345]86-*-*.
877 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
879 * ns532.c, ns532.h: New Files. ns532 support.
881 * config/mt-ns532: New File. ns532 support.
883 * gprof.c: user register int i instead of defaulting the int.
884 Allows compilation with -Dregister= for debugging.
886 * configure.in: Add ns532 support.
888 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
890 * Makefile.in (gprof): Depend on $(LIBS).
892 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
894 From binutils-2.4 release:
896 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
898 * configure.bat: [new] build makefile from makefile.in (dos)
899 * hertz.c: allow static HERTZ (msdos needs it)
900 * gprof.c: allow target to select "r" or "rb" for fopen
901 * gprof.c: ignore __gnu_compiled symbols
902 * i386.h: dfine FOPEN_RB to "rb" for dos.
904 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
906 * Makefile.in (.m.c:): Added .SUFFIXES : .m
907 so flat_bl.c would make from flat_bl.m file.
909 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
911 * Makefile.in (install-info): Check for gprof.info in build dir,
912 fall back to srcdir. Depend on it.
914 * gprof.h (TRUE, FALSE): Always use undef before defining them.
916 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
918 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
919 makes (osf1) in which the value of MACHINE can not be changed.
920 * config/*.mt: Changed appropriately.
922 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
924 * gprof.c (getsymtab): Change nosyms to long. Rename
925 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
926 errors from bfd_get_symtab_upper_bound and
927 bfd_canonicalize_symtab.
929 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
931 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
934 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
936 * Makefile.in: Avoid bug in hpux sed.
938 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
940 * gprof.texi (Invoking): add text about -v flag
942 * gprof.1: add text about -v flag
944 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
946 * gprof.c (VERSION): defined a version macro, print the value
947 when the -v option is used
949 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
951 * Makefile.in: Install correctly.
953 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
955 * gprof.c (main): Get whoami from argv, instead of hardcoding.
956 Use it in usage message. Split usage message to fit in 80 cols.
958 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
960 * Makefile.in: Undo 15 June change.
962 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
964 * gmon.h, gprof.h: structs of chars used to hold external
966 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
969 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
971 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
973 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
975 * Makefile.in: remove parentdir support
977 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
979 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
980 * configure.in: No longer need to configure to get sysdep.h.
982 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
984 * Makefile.in (install): should not depend on install-info
986 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
988 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
990 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
992 * M Makefile.in: Add -g to CFLAGS.
993 Ads LDFLAGS and use in place of CFLAGS where appropriate.
994 * configure.in: Make a sysdep.hlink in the same way other
995 bfd-based directories do.
996 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
998 * gprof.h: #include sysdep.h instead of a bunch of stuff.
999 * gprof.c (main): Fix typo gproff->gprof.
1001 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1003 * gprof.texi: add INFO-DIR-ENTRY
1005 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1007 * Makefile.in: add installcheck target
1009 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
1011 * gprof.c (funcsymbol): Invert test for aflag.
1013 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
1015 * printgprof (xmalloc, xrealloc): Cast results of malloc
1018 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
1020 * Makefile.in: created info, install-info, dvi
1022 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1024 * Makefile.in: fix install rule for $(PROG)
1026 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
1028 * gprof.1: updated SYNOPSIS to match actual behavior.
1030 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
1032 * gen-c-prog.awk: New awk script, lightly changed from
1033 previously deleted make-c-prog.awk. Converts a text file
1034 to a c function that prints that text.
1035 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
1036 Inputs to gen-c-prog.awk, containing text describing
1038 * blurbs.c: Removed. Use *_bl.c instead.
1039 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1040 from *_bl.m files. Also, improve *clean rules.
1041 * printgprof.c (printgprof): Usw new function names from *_bl.c.
1044 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
1046 * gprof.h, gprof.c, printfgprof.c: Add support for two
1047 output styles: The default is similar to the old FSF gprof,
1048 while -T sets the variable bsd_style_output, which causes
1049 output matching Berkeley's gprof. The biggest differences
1050 are that with the FSF style output, the flat profile comes
1051 before the call graph; numbers come before explanations;
1052 and there is less gratuitous white space.
1053 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
1054 variable causes discarding of initial underscores when
1055 printing symbol names. It is set unless there is a "main"
1056 symbol (without an underscore).
1057 * printfgprof.c: New function printnameonly(), called
1058 by printname(). It handles stripping of initial '_',
1059 as well as C++ name-demangling.
1060 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
1061 It is just as convenient to edit blurbs.c directly.
1062 * Makefile.in: Removed rule for making blurbs.c.
1063 * blurbs.c: This is now a true source file (as opposed
1064 to being generated from gprof.callg and gprof.flat).
1065 Change style to use one long string literal, instead of
1066 one literal per output line. Add FSF-style blurb for call graph.
1068 Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
1070 * Makefile.in: always create installation directories.
