540 * symtab.c (symtab_finalize): ensure globals symbols really
541 are favored over static ones---even if their name looks less
542 preferable; this is important for HP-UX; for example, there
543 is a static label Ltext_something that aliases the global
546 * hist.c (hist_print): auto-scaling is now in effect for FSF-style
547 output only; also, auto-scaling is now performed based on
548 per-call, rather than total execution time, which is what it was
551 * gprof.h (File_Format): new type.
553 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
554 sync with Cygnus version numbers though...
556 (long_options): renamed --gmon-info to --file-info, --width added,
557 renamed --old-file-format to --file-format
558 (main): dito; also added support to read prof files, but as
559 mon_out_read() is not implemented, it's #ifdef'd out for now
561 (usage): update to reflect new options.
563 * gmon_io.c: replaced "old_file_format" by more general
566 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
568 * core.c (core_sym_class): added back check for __gnu_compiled and
569 ___gnu_compiled for the benefit of systems without
570 bfd_find_nearest_line() support
572 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
573 with section-relative addresses
575 (core_create_function_syms): get_src_info() calls are currently
576 enabled for OSF/1 only. It appears to work allright for SunOS
577 4.1.x as well, but on SPARCs it gets painfully slow with the
578 current implementation of aout_32_find_nearest_line();
579 unfortunately, this means that static functions will not have their
580 filename printed in the call-graph function index; line-level
581 profiling should still work, but requires some patience
583 * cg_print.c (cg_print_index): sanitised printing of index when
584 using FSF-style output; in particular, output width is now controlled
585 via option --width and the function tries hard to keep columns
586 aligned even in the presence of (occasional) long names
588 * NOTES: a first shot at updating the documentation.
590 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
592 * core.c (core_create_function_syms): fixed computation of min_vma
595 * *.c: removed rcsid.
597 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
599 * Lots of changes from David Mosberger-Tang:
601 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
603 * gprof.c (main): put parentheses around & within &&.
605 * basic_blocks.c (bb_read_rec): print warning message (once) when
606 ignoring basic-block execution counts.
608 * source.c (source_file_lookup_name): corrected second argument to
611 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
612 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
614 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
615 supported both for old and new (versioned) gmon.out files. Old
616 files are identified as version 0.
618 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
619 long (instead of 4) because that is what OSF/1 v3.0 uses.
621 * core.c: minor fixes and debugging info changes.
623 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
625 * core.c (core_init): if .text cannot be found, try $CODE$ (the
626 name of the text-section under HP-UX).
628 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
629 points one past the last sampling bin, so hist_scale should be
630 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
633 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
636 * configure.in: added alpha-*-*) for per-target config.
638 * alpha.c, alpha.h: created.
640 * gprof.c (default_excluded_list): <locore>, <hicore> added.
642 * core.c (core_create_function_syms, core_create_line_syms):
643 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
644 all addresses outside the text-space. Thus, sym_lookup(&symtab,
645 addr) continues to guarantee not to return 0 on any address. It
646 also avoids incorrectly crediting the first/last symbol in the
649 * core.c (core_create_line_syms): always create function symbols
650 first, then merge in line symbols; this is so that if parts of the
651 program were compiled without -g, function-level symbols are
654 * utils.c (print_name_only): support for print_path added.
656 * symtab.c (cmp_addr): also use is_func flag in comparison.
657 (symtab_finalize): return immediately when table empty; now
658 more careful about getting rid of the right duplicate symbol.
660 * sparc.c (find_call): many fixes---this function was rather
661 botched in binutils-2.4 already; it should work again.
663 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
664 not good to rely on get_src_info() to return distinct string
667 * search_list.c (search_list_append): added cast for xmalloc().
669 * hist.c: added explicit initialization to some of the global
670 variables; fixed SItab (scales were off by a factor of 10).
672 * hist.h: include of bfd.h added.
674 * gprof.c, gprof.h (print_path): added.
676 * gprof.h (MAX): fixed.
678 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
680 * gmon_io.c: added some casts to (long) so we can always print as %lx
682 * core.c (core_get_text_space): fixed to make it work.
684 * cg_print.c (cg_print_index): added support for print_path option.
686 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
688 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
689 as some compilers complain (e.g., DEC's OSF/1 compiler)
691 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
692 symtab.c: calls to memset() had 2nd and 3rd args reversed.
694 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
696 * gprof.c: added "_mcount" to default_excluded_list.
697 (main): if output_style==0 and there is either a histogram or a
698 call-graph, always generate flat and call-graph, no matter what
699 line_granularity is set to.
701 * source.c (source_file_lookup_name): if searching for sf->name
702 fails, try again with filename obtained after stripping off any
703 partial path from sf->name.
705 * gprof.h (SRCDEBUG): added.
707 * search_list.c (search_list_append): directories were added in wrong
710 * reimplemented selection mechanism from ground up; it is now possible
711 to accurately control what gets included/excluded in each of the
712 output styles; a "symbol-specification" (spec) is the basic means
713 to select a set of symbols; a spec has the syntax:
715 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
718 any of the terminal symbols can be empty, in which case they
719 match anything (wildcards). NAME is interpreted as a FILENAME
720 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
721 with a digit, and as FUNCNAME otherwise.
723 For example, to get a call-graph display that ignores arcs
724 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
725 show only arcs into bar() (no matter what the caller),
726 you'd say "--graph=/bar"; and to get a call-graph without
727 any arc info, you'd say "--graph=/"; similarly, to
728 get a flat profile without mcount, you'd say "--no-flat=mcount"
729 and to get a flat profile that shows includes all functions
730 you'd say "--flat=""" (i.e., an empty spec)
732 * hist.c (hist_print): top_time wasn't initialized to 0.0.
734 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
736 * gmon_out.h: all headers now declared in terms of characters
737 to avoid getting into trouble with different compilers introducing
738 different amount of padding; the code already accessed the fields
739 through bfd functions, so that didn't have to change.
741 * hist.c (hist_read_rec, hist_write_rec): added support for
742 collection pc histograms measuring quantities other than time;
743 the histogram header now includes a field that specifies the
744 dimension of the quantity measured by the histogram bins
745 (normally, this is "seconds", but other meaningful dimensions
746 include such things as "I-cache misses", "instruction issue stalls"
747 etc.); there is also a field to specify a one-character
748 abbreviation for the dimension; in the case of time, this would
749 be 's'; in most other cases it probably would be '1' (not a physical
752 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
754 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
755 has become old_file_version; gmon_io.c now always supports old-style
756 gmon.out files; it first tries to read gmon.out as a new version
757 file, if that fails, it tries to read it in the old format;
758 although not very likely, it is possible for gprof to mistake an
759 old-style file as a new one (the first 4 bytes would have to
760 be "gmon"---including the trailing '\0'); in that case, it is
761 necessary to specify --old-file-version
763 * gprof.h: removed dependency on SYSV; the code now always uses
764 strrchr(), memset(), and memcpy() and does not include either
765 of string.h or strings.h; this should make gprof compile on
766 any (Unix) system without configuration (per suggestion of
769 * gprof.c (usage): fixed location of --new-file-format option.
771 * cg_arcs.c (propagate_flags): fixed typo in declaration.
773 * flat_bl.m: removed formfeed at end of file; the form-feed
774 is now printed cg_print.c only when necessary.
776 * major rewrite of gprof---too many changes to mention all of
779 + -l now requests profiling at the line level (as opposed
780 to function level); in this mode, gprof creates a "symbol"
781 (aka name-list entry) for each line of source code, instead
784 + support for a new gmon.out file format; the new format
785 consists of a header with a magic and a version number,
786 followed by a sequence of profile data; profile data
787 can any of: (a) PC histogram, (b) call-graph arcs, or
788 (c) basic-block execution counts; the version number makes
789 it possible to extend gmon.out in a backwards compatible
792 + support for tcov style annotated output: if the gmon.out file
793 contains basic-block execution counts, the user can request
794 the generation of annotated source files, much like Sun's
799 + new scheme to suppress symbols that aren't function names
800 (e.g., avoids mistaking a goto label as a function)
802 + reorganized source code to make it more managable; as a
803 side effect, gprof now compiles cleanly with "gcc -Wall"
805 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
807 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
808 final cross-check to determine whether a static symbol should be
809 considered as a function-name.
811 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
813 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
814 stdin; this is useful if you wanna keep gmon.out files compressed;
815 this way you can "gzcat" the compressed file into gprof.
817 * gprof.c: flag_min_count now initialized with 1 instead of 0.
819 * basic_blocks.c (bb_annotate_source): added support for creating
820 .tcov files when option flag_annotate_make_files is TRUE.
821 (annotate_with_count): all counts less than the minimum count
822 specified by -m are now annotated with hash-marks.
824 * gprof.c (main): -A is now followed by a string of option chars.
826 * basic_blocks.c (annotate_with_count): replaced b->count with
829 * source.c: flag_annotate_source replaced by source_lock_map.
831 * source.h: source_lock_map added.
833 * gprof.c (main): new command-line syntax: -S simply specifies
834 which source-files user is interested in; -A requests annotated
835 source files and -AA requests that all lines in a source file
838 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
840 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
842 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
843 so s_lowpc etc. get declared.
845 * arcs.h (doarcs): created.
847 * arcs.c: reordered static functions such that they get defined
850 * gprof.c (main): added options:
851 -A: request annotation of all source lines (with -S)
852 -m: minimum execution count (with default basic-block display)
853 -N: force new file format (only if BSD_COMPATIBLE is defined)
854 -S: annotate source file
855 -t: set table length (with -S)
857 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
860 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
862 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
863 on the fact being able to store a long in a double without loss of
864 precision; this does not hold on machines with 64 bit longs and 64
867 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
869 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
870 greater than 0.0. Suggested by Harold Assink
871 <carlo@sg.tn.tudelft.nl>.
873 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
875 * printgprof.c (printprof): Use free, not cfree.
876 (printgprof, printindex): Ditto.
878 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
880 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
881 decls extern to keep native HP compiler quiet.
883 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
885 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
886 __gnu_compiled, for the benefit of systems which add a leading
889 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
891 * configure.in: Change i386-*-* to i[345]86-*-*.
893 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
895 * ns532.c, ns532.h: New Files. ns532 support.
897 * config/mt-ns532: New File. ns532 support.
899 * gprof.c: user register int i instead of defaulting the int.
900 Allows compilation with -Dregister= for debugging.
902 * configure.in: Add ns532 support.
904 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
906 * Makefile.in (gprof): Depend on $(LIBS).
908 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
910 From binutils-2.4 release:
912 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
914 * configure.bat: [new] build makefile from makefile.in (dos)
915 * hertz.c: allow static HERTZ (msdos needs it)
916 * gprof.c: allow target to select "r" or "rb" for fopen
917 * gprof.c: ignore __gnu_compiled symbols
918 * i386.h: dfine FOPEN_RB to "rb" for dos.
920 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
922 * Makefile.in (.m.c:): Added .SUFFIXES : .m
923 so flat_bl.c would make from flat_bl.m file.
925 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
927 * Makefile.in (install-info): Check for gprof.info in build dir,
928 fall back to srcdir. Depend on it.
930 * gprof.h (TRUE, FALSE): Always use undef before defining them.
932 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
934 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
935 makes (osf1) in which the value of MACHINE can not be changed.
936 * config/*.mt: Changed appropriately.
938 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
940 * gprof.c (getsymtab): Change nosyms to long. Rename
941 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
942 errors from bfd_get_symtab_upper_bound and
943 bfd_canonicalize_symtab.
945 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
947 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
950 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
952 * Makefile.in: Avoid bug in hpux sed.
954 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
956 * gprof.texi (Invoking): add text about -v flag

960 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
962 * gprof.c (VERSION): defined a version macro, print the value
963 when the -v option is used
965 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
967 * Makefile.in: Install correctly.
969 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
971 * gprof.c (main): Get whoami from argv, instead of hardcoding.
972 Use it in usage message. Split usage message to fit in 80 cols.
974 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
976 * Makefile.in: Undo 15 June change.
978 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
980 * gmon.h, gprof.h: structs of chars used to hold external
982 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
985 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
987 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
989 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
991 * Makefile.in: remove parentdir support
993 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
995 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
996 * configure.in: No longer need to configure to get sysdep.h.
998 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1000 * Makefile.in (install): should not depend on install-info
1002 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
1004 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
1006 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
1008 * M Makefile.in: Add -g to CFLAGS.
1009 Ads LDFLAGS and use in place of CFLAGS where appropriate.
1010 * configure.in: Make a sysdep.hlink in the same way other
1011 bfd-based directories do.
1012 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
1014 * gprof.h: #include sysdep.h instead of a bunch of stuff.
1015 * gprof.c (main): Fix typo gproff->gprof.
1017 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1019 * gprof.texi: add INFO-DIR-ENTRY
1021 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1023 * Makefile.in: add installcheck target
1025 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
1027 * gprof.c (funcsymbol): Invert test for aflag.
1029 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
1031 * printgprof (xmalloc, xrealloc): Cast results of malloc
1034 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
1036 * Makefile.in: created info, install-info, dvi
1038 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1040 * Makefile.in: fix install rule for $(PROG)
1042 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
1044 * gprof.1: updated SYNOPSIS to match actual behavior.
1046 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
1048 * gen-c-prog.awk: New awk script, lightly changed from
1049 previously deleted make-c-prog.awk. Converts a text file
1050 to a c function that prints that text.
1051 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
1052 Inputs to gen-c-prog.awk, containing text describing
1054 * blurbs.c: Removed. Use *_bl.c instead.
1055 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1056 from *_bl.m files. Also, improve *clean rules.
1057 * printgprof.c (printgprof): Usw new function names from *_bl.c.
1060 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
1062 * gprof.h, gprof.c, printfgprof.c: Add support for two
1063 output styles: The default is similar to the old FSF gprof,
1064 while -T sets the variable bsd_style_output, which causes
1065 output matching Berkeley's gprof. The biggest differences
1066 are that with the FSF style output, the flat profile comes
1067 before the call graph; numbers come before explanations;
1068 and there is less gratuitous white space.
1069 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
1070 variable causes discarding of initial underscores when
1071 printing symbol names. It is set unless there is a "main"
1072 symbol (without an underscore).
1073 * printfgprof.c: New function printnameonly(), called
1074 by printname(). It handles stripping of initial '_',
1075 as well as C++ name-demangling.
1076 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
1077 It is just as convenient to edit blurbs.c directly.
1078 * Makefile.in: Removed rule for making blurbs.c.
1079 * blurbs.c: This is now a true source file (as opposed
1080 to being generated from gprof.callg and gprof.flat).
1081 Change style to use one long string literal, instead of
1082 one literal per output line. Add FSF-style blurb for call graph.

1107 * make-c-prog.awk: which processes text files into C programs.
1108 * printgprof.c (flatprofheader, gprofheader): Call new functions
1110 (printblurb): Remove.
1111 * Makefile.in: Infrastructure to build blurbs.

1127 help in debugging the problem (with -DDEBUG)
1128 * gprof.c: symbol values are now real values, don't add the vma
1129 anymore. (done for solaris; should verify this on other platforms)
1130 * ChangeLog: created.
