538 renamed --old-file-format to --file-format
539 (main): dito; also added support to read prof files, but as
540 mon_out_read() is not implemented, it's #ifdef'd out for now
542 (usage): update to reflect new options.
544 * gmon_io.c: replaced "old_file_format" by more general
547 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
549 * core.c (core_sym_class): added back check for __gnu_compiled and
550 ___gnu_compiled for the benefit of systems without
551 bfd_find_nearest_line() support
553 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
554 with section-relative addresses
556 (core_create_function_syms): get_src_info() calls are currently
557 enabled for OSF/1 only. It appears to work allright for SunOS
558 4.1.x as well, but on SPARCs it gets painfully slow with the
559 current implementation of aout_32_find_nearest_line();
560 unfortunately, this means that static functions will not have their
561 filename printed in the call-graph function index; line-level
562 profiling should still work, but requires some patience
564 * cg_print.c (cg_print_index): sanitised printing of index when
565 using FSF-style output; in particular, output width is now controlled
566 via option --width and the function tries hard to keep columns
567 aligned even in the presence of (occasional) long names
569 * NOTES: a first shot at updating the documentation.
571 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
573 * core.c (core_create_function_syms): fixed computation of min_vma
576 * *.c: removed rcsid.
578 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
580 * Lots of changes from David Mosberger-Tang:
582 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
584 * gprof.c (main): put parentheses around & within &&.
586 * basic_blocks.c (bb_read_rec): print warning message (once) when
587 ignoring basic-block execution counts.
589 * source.c (source_file_lookup_name): corrected second argument to
592 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
593 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
595 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
596 supported both for old and new (versioned) gmon.out files. Old
597 files are identified as version 0.
599 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
600 long (instead of 4) because that is what OSF/1 v3.0 uses.
602 * core.c: minor fixes and debugging info changes.
604 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
606 * core.c (core_init): if .text cannot be found, try $CODE$ (the
607 name of the text-section under HP-UX).
609 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
610 points one past the last sampling bin, so hist_scale should be
611 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
614 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
617 * configure.in: added alpha-*-*) for per-target config.
619 * alpha.c, alpha.h: created.
621 * gprof.c (default_excluded_list): <locore>, <hicore> added.
623 * core.c (core_create_function_syms, core_create_line_syms):
624 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
625 all addresses outside the text-space. Thus, sym_lookup(&symtab,
626 addr) continues to guarantee not to return 0 on any address. It
627 also avoids incorrectly crediting the first/last symbol in the
630 * core.c (core_create_line_syms): always create function symbols
631 first, then merge in line symbols; this is so that if parts of the
632 program were compiled without -g, function-level symbols are
635 * utils.c (print_name_only): support for print_path added.
637 * symtab.c (cmp_addr): also use is_func flag in comparison.
638 (symtab_finalize): return immediately when table empty; now
639 more careful about getting rid of the right duplicate symbol.
641 * sparc.c (find_call): many fixes---this function was rather
642 botched in binutils-2.4 already; it should work again.
644 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
645 not good to rely on get_src_info() to return distinct string
648 * search_list.c (search_list_append): added cast for xmalloc().
650 * hist.c: added explicit initialization to some of the global
651 variables; fixed SItab (scales were off by a factor of 10).
653 * hist.h: include of bfd.h added.
655 * gprof.c, gprof.h (print_path): added.
657 * gprof.h (MAX): fixed.
659 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
661 * gmon_io.c: added some casts to (long) so we can always print as %lx
663 * core.c (core_get_text_space): fixed to make it work.
665 * cg_print.c (cg_print_index): added support for print_path option.
667 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
669 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
670 as some compilers complain (e.g., DEC's OSF/1 compiler)
672 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
673 symtab.c: calls to memset() had 2nd and 3rd args reversed.
675 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
677 * gprof.c: added "_mcount" to default_excluded_list.
678 (main): if output_style==0 and there is either a histogram or a
679 call-graph, always generate flat and call-graph, no matter what
680 line_granularity is set to.
682 * source.c (source_file_lookup_name): if searching for sf->name
683 fails, try again with filename obtained after stripping off any
684 partial path from sf->name.
686 * gprof.h (SRCDEBUG): added.
688 * search_list.c (search_list_append): directories were added in wrong
691 * reimplemented selection mechanism from ground up; it is now possible
692 to accurately control what gets included/excluded in each of the
693 output styles; a "symbol-specification" (spec) is the basic means
694 to select a set of symbols; a spec has the syntax:
696 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
699 any of the terminal symbols can be empty, in which case they
700 match anything (wildcards). NAME is interpreted as a FILENAME
701 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
702 with a digit, and as FUNCNAME otherwise.
704 For example, to get a call-graph display that ignores arcs
705 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
706 show only arcs into bar() (no matter what the caller),
707 you'd say "--graph=/bar"; and to get a call-graph without
708 any arc info, you'd say "--graph=/"; similarly, to
709 get a flat profile without mcount, you'd say "--no-flat=mcount"
710 and to get a flat profile that shows includes all functions
711 you'd say "--flat=""" (i.e., an empty spec)
713 * hist.c (hist_print): top_time wasn't initialized to 0.0.
715 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
717 * gmon_out.h: all headers now declared in terms of characters
718 to avoid getting into trouble with different compilers introducing
719 different amount of padding; the code already accessed the fields
720 through bfd functions, so that didn't have to change.
722 * hist.c (hist_read_rec, hist_write_rec): added support for
723 collection pc histograms measuring quantities other than time;
724 the histogram header now includes a field that specifies the
725 dimension of the quantity measured by the histogram bins
726 (normally, this is "seconds", but other meaningful dimensions
727 include such things as "I-cache misses", "instruction issue stalls"
728 etc.); there is also a field to specify a one-character
729 abbreviation for the dimension; in the case of time, this would
730 be 's'; in most other cases it probably would be '1' (not a physical
733 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
735 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
736 has become old_file_version; gmon_io.c now always supports old-style
737 gmon.out files; it first tries to read gmon.out as a new version
738 file, if that fails, it tries to read it in the old format;
739 although not very likely, it is possible for gprof to mistake an
740 old-style file as a new one (the first 4 bytes would have to
741 be "gmon"---including the trailing '\0'); in that case, it is
742 necessary to specify --old-file-version
744 * gprof.h: removed dependency on SYSV; the code now always uses
745 strrchr(), memset(), and memcpy() and does not include either
746 of string.h or strings.h; this should make gprof compile on
747 any (Unix) system without configuration (per suggestion of
750 * gprof.c (usage): fixed location of --new-file-format option.
752 * cg_arcs.c (propagate_flags): fixed typo in declaration.
754 * flat_bl.m: removed formfeed at end of file; the form-feed
755 is now printed cg_print.c only when necessary.
757 * major rewrite of gprof---too many changes to mention all of
760 + -l now requests profiling at the line level (as opposed
761 to function level); in this mode, gprof creates a "symbol"
762 (aka name-list entry) for each line of source code, instead
765 + support for a new gmon.out file format; the new format
766 consists of a header with a magic and a version number,
767 followed by a sequence of profile data; profile data
768 can any of: (a) PC histogram, (b) call-graph arcs, or
769 (c) basic-block execution counts; the version number makes
770 it possible to extend gmon.out in a backwards compatible
773 + support for tcov style annotated output: if the gmon.out file
774 contains basic-block execution counts, the user can request
775 the generation of annotated source files, much like Sun's
780 + new scheme to suppress symbols that aren't function names
781 (e.g., avoids mistaking a goto label as a function)
783 + reorganized source code to make it more managable; as a
784 side effect, gprof now compiles cleanly with "gcc -Wall"
786 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
788 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
789 final cross-check to determine whether a static symbol should be
790 considered as a function-name.
792 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
794 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
795 stdin; this is useful if you wanna keep gmon.out files compressed;
796 this way you can "gzcat" the compressed file into gprof.
798 * gprof.c: flag_min_count now initialized with 1 instead of 0.
800 * basic_blocks.c (bb_annotate_source): added support for creating
801 .tcov files when option flag_annotate_make_files is TRUE.
802 (annotate_with_count): all counts less than the minimum count
803 specified by -m are now annotated with hash-marks.
805 * gprof.c (main): -A is now followed by a string of option chars.
807 * basic_blocks.c (annotate_with_count): replaced b->count with
810 * source.c: flag_annotate_source replaced by source_lock_map.
812 * source.h: source_lock_map added.
814 * gprof.c (main): new command-line syntax: -S simply specifies
815 which source-files user is interested in; -A requests annotated
816 source files and -AA requests that all lines in a source file
819 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
821 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
823 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
824 so s_lowpc etc. get declared.
826 * arcs.h (doarcs): created.
828 * arcs.c: reordered static functions such that they get defined
831 * gprof.c (main): added options:
832 -A: request annotation of all source lines (with -S)
833 -m: minimum execution count (with default basic-block display)
834 -N: force new file format (only if BSD_COMPATIBLE is defined)
835 -S: annotate source file
836 -t: set table length (with -S)
838 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
841 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
843 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
844 on the fact being able to store a long in a double without loss of
845 precision; this does not hold on machines with 64 bit longs and 64
848 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
850 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
851 greater than 0.0. Suggested by Harold Assink
852 <carlo@sg.tn.tudelft.nl>.
854 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
856 * printgprof.c (printprof): Use free, not cfree.
857 (printgprof, printindex): Ditto.
859 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
861 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
862 decls extern to keep native HP compiler quiet.
864 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
866 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
867 __gnu_compiled, for the benefit of systems which add a leading
870 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
872 * configure.in: Change i386-*-* to i[345]86-*-*.
874 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
876 * ns532.c, ns532.h: New Files. ns532 support.
878 * config/mt-ns532: New File. ns532 support.
880 * gprof.c: user register int i instead of defaulting the int.
881 Allows compilation with -Dregister= for debugging.
883 * configure.in: Add ns532 support.
885 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
887 * Makefile.in (gprof): Depend on $(LIBS).
889 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
891 From binutils-2.4 release:
893 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
895 * configure.bat: [new] build makefile from makefile.in (dos)
896 * hertz.c: allow static HERTZ (msdos needs it)
897 * gprof.c: allow target to select "r" or "rb" for fopen
898 * gprof.c: ignore __gnu_compiled symbols
899 * i386.h: dfine FOPEN_RB to "rb" for dos.
901 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
903 * Makefile.in (.m.c:): Added .SUFFIXES : .m
904 so flat_bl.c would make from flat_bl.m file.
906 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
908 * Makefile.in (install-info): Check for gprof.info in build dir,
909 fall back to srcdir. Depend on it.
911 * gprof.h (TRUE, FALSE): Always use undef before defining them.
913 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
915 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
916 makes (osf1) in which the value of MACHINE can not be changed.
917 * config/*.mt: Changed appropriately.
919 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
921 * gprof.c (getsymtab): Change nosyms to long. Rename
922 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
923 errors from bfd_get_symtab_upper_bound and
924 bfd_canonicalize_symtab.
926 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
928 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
931 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
933 * Makefile.in: Avoid bug in hpux sed.
935 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
937 * gprof.texi (Invoking): add text about -v flag
939 * gprof.1: add text about -v flag
941 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
943 * gprof.c (VERSION): defined a version macro, print the value
944 when the -v option is used
946 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
948 * Makefile.in: Install correctly.
950 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
952 * gprof.c (main): Get whoami from argv, instead of hardcoding.
953 Use it in usage message. Split usage message to fit in 80 cols.
955 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
957 * Makefile.in: Undo 15 June change.
959 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
961 * gmon.h, gprof.h: structs of chars used to hold external
963 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
966 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
968 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
970 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
972 * Makefile.in: remove parentdir support
974 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
976 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
977 * configure.in: No longer need to configure to get sysdep.h.
979 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
981 * Makefile.in (install): should not depend on install-info
983 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
985 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
987 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
989 * M Makefile.in: Add -g to CFLAGS.
990 Ads LDFLAGS and use in place of CFLAGS where appropriate.
991 * configure.in: Make a sysdep.hlink in the same way other
992 bfd-based directories do.
993 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
995 * gprof.h: #include sysdep.h instead of a bunch of stuff.
996 * gprof.c (main): Fix typo gproff->gprof.
998 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1000 * gprof.texi: add INFO-DIR-ENTRY
1002 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1004 * Makefile.in: add installcheck target
1006 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
1008 * gprof.c (funcsymbol): Invert test for aflag.
1010 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
1012 * printgprof (xmalloc, xrealloc): Cast results of malloc
1015 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
1017 * Makefile.in: created info, install-info, dvi
1019 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1021 * Makefile.in: fix install rule for $(PROG)
1023 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
1025 * gprof.1: updated SYNOPSIS to match actual behavior.
1027 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
1029 * gen-c-prog.awk: New awk script, lightly changed from
1030 previously deleted make-c-prog.awk. Converts a text file
1031 to a c function that prints that text.
1032 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
1033 Inputs to gen-c-prog.awk, containing text describing
1035 * blurbs.c: Removed. Use *_bl.c instead.
1036 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1037 from *_bl.m files. Also, improve *clean rules.
1038 * printgprof.c (printgprof): Usw new function names from *_bl.c.
1041 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
1043 * gprof.h, gprof.c, printfgprof.c: Add support for two
1044 output styles: The default is similar to the old FSF gprof,
1045 while -T sets the variable bsd_style_output, which causes
1046 output matching Berkeley's gprof. The biggest differences
1047 are that with the FSF style output, the flat profile comes
1048 before the call graph; numbers come before explanations;
1049 and there is less gratuitous white space.
1050 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
1051 variable causes discarding of initial underscores when
1052 printing symbol names. It is set unless there is a "main"
1053 symbol (without an underscore).
1054 * printfgprof.c: New function printnameonly(), called
1055 by printname(). It handles stripping of initial '_',
1056 as well as C++ name-demangling.
1057 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
1058 It is just as convenient to edit blurbs.c directly.
1059 * Makefile.in: Removed rule for making blurbs.c.
1060 * blurbs.c: This is now a true source file (as opposed
1061 to being generated from gprof.callg and gprof.flat).
1062 Change style to use one long string literal, instead of
1063 one literal per output line. Add FSF-style blurb for call graph.
1065 Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
1067 * Makefile.in: always create installation directories.
1069 Wed Aug 12 15:14:14 1992 Mark Eichin (eichin@cygnus.com)
