536 per-call, rather than total execution time, which is what it was
539 * gprof.h (File_Format): new type.
541 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
542 sync with Cygnus version numbers though...
544 (long_options): renamed --gmon-info to --file-info, --width added,
545 renamed --old-file-format to --file-format
546 (main): dito; also added support to read prof files, but as
547 mon_out_read() is not implemented, it's #ifdef'd out for now
549 (usage): update to reflect new options.
551 * gmon_io.c: replaced "old_file_format" by more general
554 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
556 * core.c (core_sym_class): added back check for __gnu_compiled and
557 ___gnu_compiled for the benefit of systems without
558 bfd_find_nearest_line() support
560 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
561 with section-relative addresses
563 (core_create_function_syms): get_src_info() calls are currently
564 enabled for OSF/1 only. It appears to work allright for SunOS
565 4.1.x as well, but on SPARCs it gets painfully slow with the
566 current implementation of aout_32_find_nearest_line();
567 unfortunately, this means that static functions will not have their
568 filename printed in the call-graph function index; line-level
569 profiling should still work, but requires some patience
571 * cg_print.c (cg_print_index): sanitised printing of index when
572 using FSF-style output; in particular, output width is now controlled
573 via option --width and the function tries hard to keep columns
574 aligned even in the presence of (occasional) long names
576 * NOTES: a first shot at updating the documentation.
578 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
580 * core.c (core_create_function_syms): fixed computation of min_vma
583 * *.c: removed rcsid.
585 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
587 * Lots of changes from David Mosberger-Tang:
589 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
591 * gprof.c (main): put parentheses around & within &&.
593 * basic_blocks.c (bb_read_rec): print warning message (once) when
594 ignoring basic-block execution counts.
596 * source.c (source_file_lookup_name): corrected second argument to
599 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
600 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
602 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
603 supported both for old and new (versioned) gmon.out files. Old
604 files are identified as version 0.
606 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
607 long (instead of 4) because that is what OSF/1 v3.0 uses.
609 * core.c: minor fixes and debugging info changes.
611 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
613 * core.c (core_init): if .text cannot be found, try $CODE$ (the
614 name of the text-section under HP-UX).
616 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
617 points one past the last sampling bin, so hist_scale should be
618 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
621 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
624 * configure.in: added alpha-*-*) for per-target config.
626 * alpha.c, alpha.h: created.
628 * gprof.c (default_excluded_list): <locore>, <hicore> added.
630 * core.c (core_create_function_syms, core_create_line_syms):
631 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
632 all addresses outside the text-space. Thus, sym_lookup(&symtab,
633 addr) continues to guarantee not to return 0 on any address. It
634 also avoids incorrectly crediting the first/last symbol in the
637 * core.c (core_create_line_syms): always create function symbols
638 first, then merge in line symbols; this is so that if parts of the
639 program were compiled without -g, function-level symbols are
642 * utils.c (print_name_only): support for print_path added.
644 * symtab.c (cmp_addr): also use is_func flag in comparison.
645 (symtab_finalize): return immediately when table empty; now
646 more careful about getting rid of the right duplicate symbol.
648 * sparc.c (find_call): many fixes---this function was rather
649 botched in binutils-2.4 already; it should work again.
651 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
652 not good to rely on get_src_info() to return distinct string
655 * search_list.c (search_list_append): added cast for xmalloc().
657 * hist.c: added explicit initialization to some of the global
658 variables; fixed SItab (scales were off by a factor of 10).
660 * hist.h: include of bfd.h added.
662 * gprof.c, gprof.h (print_path): added.
664 * gprof.h (MAX): fixed.
666 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
668 * gmon_io.c: added some casts to (long) so we can always print as %lx
670 * core.c (core_get_text_space): fixed to make it work.
672 * cg_print.c (cg_print_index): added support for print_path option.
674 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
676 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
677 as some compilers complain (e.g., DEC's OSF/1 compiler)
679 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
680 symtab.c: calls to memset() had 2nd and 3rd args reversed.
682 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
684 * gprof.c: added "_mcount" to default_excluded_list.
685 (main): if output_style==0 and there is either a histogram or a
686 call-graph, always generate flat and call-graph, no matter what
687 line_granularity is set to.
689 * source.c (source_file_lookup_name): if searching for sf->name
690 fails, try again with filename obtained after stripping off any
691 partial path from sf->name.
693 * gprof.h (SRCDEBUG): added.
695 * search_list.c (search_list_append): directories were added in wrong
698 * reimplemented selection mechanism from ground up; it is now possible
699 to accurately control what gets included/excluded in each of the
700 output styles; a "symbol-specification" (spec) is the basic means
701 to select a set of symbols; a spec has the syntax:
703 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
706 any of the terminal symbols can be empty, in which case they
707 match anything (wildcards). NAME is interpreted as a FILENAME
708 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
709 with a digit, and as FUNCNAME otherwise.
711 For example, to get a call-graph display that ignores arcs
712 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
713 show only arcs into bar() (no matter what the caller),
714 you'd say "--graph=/bar"; and to get a call-graph without
715 any arc info, you'd say "--graph=/"; similarly, to
716 get a flat profile without mcount, you'd say "--no-flat=mcount"
717 and to get a flat profile that shows includes all functions
718 you'd say "--flat=""" (i.e., an empty spec)
720 * hist.c (hist_print): top_time wasn't initialized to 0.0.
722 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
724 * gmon_out.h: all headers now declared in terms of characters
725 to avoid getting into trouble with different compilers introducing
726 different amount of padding; the code already accessed the fields
727 through bfd functions, so that didn't have to change.
729 * hist.c (hist_read_rec, hist_write_rec): added support for
730 collection pc histograms measuring quantities other than time;
731 the histogram header now includes a field that specifies the
732 dimension of the quantity measured by the histogram bins
733 (normally, this is "seconds", but other meaningful dimensions
734 include such things as "I-cache misses", "instruction issue stalls"
735 etc.); there is also a field to specify a one-character
736 abbreviation for the dimension; in the case of time, this would
737 be 's'; in most other cases it probably would be '1' (not a physical
740 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
742 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
743 has become old_file_version; gmon_io.c now always supports old-style
744 gmon.out files; it first tries to read gmon.out as a new version
745 file, if that fails, it tries to read it in the old format;
746 although not very likely, it is possible for gprof to mistake an
747 old-style file as a new one (the first 4 bytes would have to
748 be "gmon"---including the trailing '\0'); in that case, it is
749 necessary to specify --old-file-version
751 * gprof.h: removed dependency on SYSV; the code now always uses
752 strrchr(), memset(), and memcpy() and does not include either
753 of string.h or strings.h; this should make gprof compile on
754 any (Unix) system without configuration (per suggestion of
757 * gprof.c (usage): fixed location of --new-file-format option.
759 * cg_arcs.c (propagate_flags): fixed typo in declaration.
761 * flat_bl.m: removed formfeed at end of file; the form-feed
762 is now printed cg_print.c only when necessary.
764 * major rewrite of gprof---too many changes to mention all of
767 + -l now requests profiling at the line level (as opposed
768 to function level); in this mode, gprof creates a "symbol"
769 (aka name-list entry) for each line of source code, instead
772 + support for a new gmon.out file format; the new format
773 consists of a header with a magic and a version number,
774 followed by a sequence of profile data; profile data
775 can any of: (a) PC histogram, (b) call-graph arcs, or
776 (c) basic-block execution counts; the version number makes
777 it possible to extend gmon.out in a backwards compatible
780 + support for tcov style annotated output: if the gmon.out file
781 contains basic-block execution counts, the user can request
782 the generation of annotated source files, much like Sun's
787 + new scheme to suppress symbols that aren't function names
788 (e.g., avoids mistaking a goto label as a function)
790 + reorganized source code to make it more managable; as a
791 side effect, gprof now compiles cleanly with "gcc -Wall"
793 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
795 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
796 final cross-check to determine whether a static symbol should be
797 considered as a function-name.
799 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
801 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
802 stdin; this is useful if you wanna keep gmon.out files compressed;
803 this way you can "gzcat" the compressed file into gprof.
805 * gprof.c: flag_min_count now initialized with 1 instead of 0.
807 * basic_blocks.c (bb_annotate_source): added support for creating
808 .tcov files when option flag_annotate_make_files is TRUE.
809 (annotate_with_count): all counts less than the minimum count
810 specified by -m are now annotated with hash-marks.
812 * gprof.c (main): -A is now followed by a string of option chars.
814 * basic_blocks.c (annotate_with_count): replaced b->count with
817 * source.c: flag_annotate_source replaced by source_lock_map.
819 * source.h: source_lock_map added.
821 * gprof.c (main): new command-line syntax: -S simply specifies
822 which source-files user is interested in; -A requests annotated
823 source files and -AA requests that all lines in a source file
826 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
828 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
830 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
831 so s_lowpc etc. get declared.
833 * arcs.h (doarcs): created.
835 * arcs.c: reordered static functions such that they get defined
838 * gprof.c (main): added options:
839 -A: request annotation of all source lines (with -S)
840 -m: minimum execution count (with default basic-block display)
841 -N: force new file format (only if BSD_COMPATIBLE is defined)
842 -S: annotate source file
843 -t: set table length (with -S)
845 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
848 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
850 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
851 on the fact being able to store a long in a double without loss of
852 precision; this does not hold on machines with 64 bit longs and 64
855 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
857 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
858 greater than 0.0. Suggested by Harold Assink
859 <carlo@sg.tn.tudelft.nl>.
861 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
863 * printgprof.c (printprof): Use free, not cfree.
864 (printgprof, printindex): Ditto.
866 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
868 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
869 decls extern to keep native HP compiler quiet.
871 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
873 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
874 __gnu_compiled, for the benefit of systems which add a leading
877 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
879 * configure.in: Change i386-*-* to i[345]86-*-*.
881 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
883 * ns532.c, ns532.h: New Files. ns532 support.
885 * config/mt-ns532: New File. ns532 support.
887 * gprof.c: user register int i instead of defaulting the int.
888 Allows compilation with -Dregister= for debugging.
890 * configure.in: Add ns532 support.
892 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
894 * Makefile.in (gprof): Depend on $(LIBS).
896 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
898 From binutils-2.4 release:
900 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
902 * configure.bat: [new] build makefile from makefile.in (dos)
903 * hertz.c: allow static HERTZ (msdos needs it)
904 * gprof.c: allow target to select "r" or "rb" for fopen
905 * gprof.c: ignore __gnu_compiled symbols
906 * i386.h: dfine FOPEN_RB to "rb" for dos.
908 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
910 * Makefile.in (.m.c:): Added .SUFFIXES : .m
911 so flat_bl.c would make from flat_bl.m file.
913 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
915 * Makefile.in (install-info): Check for gprof.info in build dir,
916 fall back to srcdir. Depend on it.
918 * gprof.h (TRUE, FALSE): Always use undef before defining them.
920 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
922 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
923 makes (osf1) in which the value of MACHINE can not be changed.
924 * config/*.mt: Changed appropriately.
926 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
928 * gprof.c (getsymtab): Change nosyms to long. Rename
929 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
930 errors from bfd_get_symtab_upper_bound and
931 bfd_canonicalize_symtab.
933 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
935 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
938 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
940 * Makefile.in: Avoid bug in hpux sed.
942 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
944 * gprof.texi (Invoking): add text about -v flag
946 * gprof.1: add text about -v flag
948 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
950 * gprof.c (VERSION): defined a version macro, print the value
951 when the -v option is used
953 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
955 * Makefile.in: Install correctly.
957 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
959 * gprof.c (main): Get whoami from argv, instead of hardcoding.
960 Use it in usage message. Split usage message to fit in 80 cols.
962 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
964 * Makefile.in: Undo 15 June change.
966 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
968 * gmon.h, gprof.h: structs of chars used to hold external
970 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
973 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
975 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
977 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
979 * Makefile.in: remove parentdir support
981 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
983 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
984 * configure.in: No longer need to configure to get sysdep.h.
986 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
988 * Makefile.in (install): should not depend on install-info
990 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
992 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
994 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
996 * M Makefile.in: Add -g to CFLAGS.
997 Ads LDFLAGS and use in place of CFLAGS where appropriate.
998 * configure.in: Make a sysdep.hlink in the same way other
999 bfd-based directories do.
1000 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
1002 * gprof.h: #include sysdep.h instead of a bunch of stuff.
1003 * gprof.c (main): Fix typo gproff->gprof.
1005 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1007 * gprof.texi: add INFO-DIR-ENTRY
1009 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1011 * Makefile.in: add installcheck target
1013 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
1015 * gprof.c (funcsymbol): Invert test for aflag.
1017 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
1019 * printgprof (xmalloc, xrealloc): Cast results of malloc
1022 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
1024 * Makefile.in: created info, install-info, dvi
1026 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1028 * Makefile.in: fix install rule for $(PROG)
1030 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
1032 * gprof.1: updated SYNOPSIS to match actual behavior.
1034 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
1036 * gen-c-prog.awk: New awk script, lightly changed from
1037 previously deleted make-c-prog.awk. Converts a text file
1038 to a c function that prints that text.
1039 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
1040 Inputs to gen-c-prog.awk, containing text describing
1042 * blurbs.c: Removed. Use *_bl.c instead.
1043 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1044 from *_bl.m files. Also, improve *clean rules.
1045 * printgprof.c (printgprof): Usw new function names from *_bl.c.
1048 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
1050 * gprof.h, gprof.c, printfgprof.c: Add support for two
1051 output styles: The default is similar to the old FSF gprof,
1052 while -T sets the variable bsd_style_output, which causes
1053 output matching Berkeley's gprof. The biggest differences
1054 are that with the FSF style output, the flat profile comes
1055 before the call graph; numbers come before explanations;
1056 and there is less gratuitous white space.
1057 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
1058 variable causes discarding of initial underscores when
1059 printing symbol names. It is set unless there is a "main"
1060 symbol (without an underscore).
1061 * printfgprof.c: New function printnameonly(), called
1062 by printname(). It handles stripping of initial '_',
1063 as well as C++ name-demangling.
1064 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
1065 It is just as convenient to edit blurbs.c directly.
1066 * Makefile.in: Removed rule for making blurbs.c.
1067 * blurbs.c: This is now a true source file (as opposed
1068 to being generated from gprof.callg and gprof.flat).
1069 Change style to use one long string literal, instead of
1070 one literal per output line. Add FSF-style blurb for call graph.
1072 Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
