538 * hist.c (hist_print): auto-scaling is now in effect for FSF-style
539 output only; also, auto-scaling is now performed based on
540 per-call, rather than total execution time, which is what it was
543 * gprof.h (File_Format): new type.
545 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
546 sync with Cygnus version numbers though...
548 (long_options): renamed --gmon-info to --file-info, --width added,
549 renamed --old-file-format to --file-format
550 (main): dito; also added support to read prof files, but as
551 mon_out_read() is not implemented, it's #ifdef'd out for now
553 (usage): update to reflect new options.
555 * gmon_io.c: replaced "old_file_format" by more general
558 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
560 * core.c (core_sym_class): added back check for __gnu_compiled and
561 ___gnu_compiled for the benefit of systems without
562 bfd_find_nearest_line() support
564 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
565 with section-relative addresses
567 (core_create_function_syms): get_src_info() calls are currently
568 enabled for OSF/1 only. It appears to work allright for SunOS
569 4.1.x as well, but on SPARCs it gets painfully slow with the
570 current implementation of aout_32_find_nearest_line();
571 unfortunately, this means that static functions will not have their
572 filename printed in the call-graph function index; line-level
573 profiling should still work, but requires some patience
575 * cg_print.c (cg_print_index): sanitised printing of index when
576 using FSF-style output; in particular, output width is now controlled
577 via option --width and the function tries hard to keep columns
578 aligned even in the presence of (occasional) long names
580 * NOTES: a first shot at updating the documentation.
582 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
584 * core.c (core_create_function_syms): fixed computation of min_vma
587 * *.c: removed rcsid.
589 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
591 * Lots of changes from David Mosberger-Tang:
593 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
595 * gprof.c (main): put parentheses around & within &&.
597 * basic_blocks.c (bb_read_rec): print warning message (once) when
598 ignoring basic-block execution counts.
600 * source.c (source_file_lookup_name): corrected second argument to
603 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
604 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
606 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
607 supported both for old and new (versioned) gmon.out files. Old
608 files are identified as version 0.
610 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
611 long (instead of 4) because that is what OSF/1 v3.0 uses.
613 * core.c: minor fixes and debugging info changes.
615 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
617 * core.c (core_init): if .text cannot be found, try $CODE$ (the
618 name of the text-section under HP-UX).
620 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
621 points one past the last sampling bin, so hist_scale should be
622 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
625 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
628 * configure.in: added alpha-*-*) for per-target config.
630 * alpha.c, alpha.h: created.
632 * gprof.c (default_excluded_list): <locore>, <hicore> added.
634 * core.c (core_create_function_syms, core_create_line_syms):
635 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
636 all addresses outside the text-space. Thus, sym_lookup(&symtab,
637 addr) continues to guarantee not to return 0 on any address. It
638 also avoids incorrectly crediting the first/last symbol in the
641 * core.c (core_create_line_syms): always create function symbols
642 first, then merge in line symbols; this is so that if parts of the
643 program were compiled without -g, function-level symbols are
646 * utils.c (print_name_only): support for print_path added.
648 * symtab.c (cmp_addr): also use is_func flag in comparison.
649 (symtab_finalize): return immediately when table empty; now
650 more careful about getting rid of the right duplicate symbol.
652 * sparc.c (find_call): many fixes---this function was rather
653 botched in binutils-2.4 already; it should work again.
655 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
656 not good to rely on get_src_info() to return distinct string
659 * search_list.c (search_list_append): added cast for xmalloc().
661 * hist.c: added explicit initialization to some of the global
662 variables; fixed SItab (scales were off by a factor of 10).
664 * hist.h: include of bfd.h added.
666 * gprof.c, gprof.h (print_path): added.
668 * gprof.h (MAX): fixed.
670 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
672 * gmon_io.c: added some casts to (long) so we can always print as %lx
674 * core.c (core_get_text_space): fixed to make it work.
676 * cg_print.c (cg_print_index): added support for print_path option.
678 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
680 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
681 as some compilers complain (e.g., DEC's OSF/1 compiler)
683 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
684 symtab.c: calls to memset() had 2nd and 3rd args reversed.
686 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
688 * gprof.c: added "_mcount" to default_excluded_list.
689 (main): if output_style==0 and there is either a histogram or a
690 call-graph, always generate flat and call-graph, no matter what
691 line_granularity is set to.
693 * source.c (source_file_lookup_name): if searching for sf->name
694 fails, try again with filename obtained after stripping off any
695 partial path from sf->name.
697 * gprof.h (SRCDEBUG): added.
699 * search_list.c (search_list_append): directories were added in wrong
702 * reimplemented selection mechanism from ground up; it is now possible
703 to accurately control what gets included/excluded in each of the
704 output styles; a "symbol-specification" (spec) is the basic means
705 to select a set of symbols; a spec has the syntax:
707 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
710 any of the terminal symbols can be empty, in which case they
711 match anything (wildcards). NAME is interpreted as a FILENAME
712 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
713 with a digit, and as FUNCNAME otherwise.
715 For example, to get a call-graph display that ignores arcs
716 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
717 show only arcs into bar() (no matter what the caller),
718 you'd say "--graph=/bar"; and to get a call-graph without
719 any arc info, you'd say "--graph=/"; similarly, to
720 get a flat profile without mcount, you'd say "--no-flat=mcount"
721 and to get a flat profile that shows includes all functions
722 you'd say "--flat=""" (i.e., an empty spec)
724 * hist.c (hist_print): top_time wasn't initialized to 0.0.
726 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
728 * gmon_out.h: all headers now declared in terms of characters
729 to avoid getting into trouble with different compilers introducing
730 different amount of padding; the code already accessed the fields
731 through bfd functions, so that didn't have to change.
733 * hist.c (hist_read_rec, hist_write_rec): added support for
734 collection pc histograms measuring quantities other than time;
735 the histogram header now includes a field that specifies the
736 dimension of the quantity measured by the histogram bins
737 (normally, this is "seconds", but other meaningful dimensions
738 include such things as "I-cache misses", "instruction issue stalls"
739 etc.); there is also a field to specify a one-character
740 abbreviation for the dimension; in the case of time, this would
741 be 's'; in most other cases it probably would be '1' (not a physical
744 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
746 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
747 has become old_file_version; gmon_io.c now always supports old-style
748 gmon.out files; it first tries to read gmon.out as a new version
749 file, if that fails, it tries to read it in the old format;
750 although not very likely, it is possible for gprof to mistake an
751 old-style file as a new one (the first 4 bytes would have to
752 be "gmon"---including the trailing '\0'); in that case, it is
753 necessary to specify --old-file-version
755 * gprof.h: removed dependency on SYSV; the code now always uses
756 strrchr(), memset(), and memcpy() and does not include either
757 of string.h or strings.h; this should make gprof compile on
758 any (Unix) system without configuration (per suggestion of
761 * gprof.c (usage): fixed location of --new-file-format option.
763 * cg_arcs.c (propagate_flags): fixed typo in declaration.
765 * flat_bl.m: removed formfeed at end of file; the form-feed
766 is now printed cg_print.c only when necessary.
768 * major rewrite of gprof---too many changes to mention all of
771 + -l now requests profiling at the line level (as opposed
772 to function level); in this mode, gprof creates a "symbol"
773 (aka name-list entry) for each line of source code, instead
776 + support for a new gmon.out file format; the new format
777 consists of a header with a magic and a version number,
778 followed by a sequence of profile data; profile data
779 can any of: (a) PC histogram, (b) call-graph arcs, or
780 (c) basic-block execution counts; the version number makes
781 it possible to extend gmon.out in a backwards compatible
784 + support for tcov style annotated output: if the gmon.out file
785 contains basic-block execution counts, the user can request
786 the generation of annotated source files, much like Sun's
791 + new scheme to suppress symbols that aren't function names
792 (e.g., avoids mistaking a goto label as a function)
794 + reorganized source code to make it more managable; as a
795 side effect, gprof now compiles cleanly with "gcc -Wall"
797 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
799 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
800 final cross-check to determine whether a static symbol should be
801 considered as a function-name.
803 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
805 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
806 stdin; this is useful if you wanna keep gmon.out files compressed;
807 this way you can "gzcat" the compressed file into gprof.
809 * gprof.c: flag_min_count now initialized with 1 instead of 0.
811 * basic_blocks.c (bb_annotate_source): added support for creating
812 .tcov files when option flag_annotate_make_files is TRUE.
813 (annotate_with_count): all counts less than the minimum count
814 specified by -m are now annotated with hash-marks.
816 * gprof.c (main): -A is now followed by a string of option chars.
818 * basic_blocks.c (annotate_with_count): replaced b->count with
821 * source.c: flag_annotate_source replaced by source_lock_map.
823 * source.h: source_lock_map added.
825 * gprof.c (main): new command-line syntax: -S simply specifies
826 which source-files user is interested in; -A requests annotated
827 source files and -AA requests that all lines in a source file
830 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
832 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
834 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
835 so s_lowpc etc. get declared.
837 * arcs.h (doarcs): created.
839 * arcs.c: reordered static functions such that they get defined
842 * gprof.c (main): added options:
843 -A: request annotation of all source lines (with -S)
844 -m: minimum execution count (with default basic-block display)
845 -N: force new file format (only if BSD_COMPATIBLE is defined)
846 -S: annotate source file
847 -t: set table length (with -S)
849 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
852 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
854 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
855 on the fact being able to store a long in a double without loss of
856 precision; this does not hold on machines with 64 bit longs and 64
859 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
861 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
862 greater than 0.0. Suggested by Harold Assink
863 <carlo@sg.tn.tudelft.nl>.
865 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
867 * printgprof.c (printprof): Use free, not cfree.
868 (printgprof, printindex): Ditto.
870 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
872 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
873 decls extern to keep native HP compiler quiet.
875 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
877 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
878 __gnu_compiled, for the benefit of systems which add a leading
881 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
883 * configure.in: Change i386-*-* to i[345]86-*-*.
885 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
887 * ns532.c, ns532.h: New Files. ns532 support.
889 * config/mt-ns532: New File. ns532 support.
891 * gprof.c: user register int i instead of defaulting the int.
892 Allows compilation with -Dregister= for debugging.
894 * configure.in: Add ns532 support.
896 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
898 * Makefile.in (gprof): Depend on $(LIBS).
900 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
902 From binutils-2.4 release:
904 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
906 * configure.bat: [new] build makefile from makefile.in (dos)
907 * hertz.c: allow static HERTZ (msdos needs it)
908 * gprof.c: allow target to select "r" or "rb" for fopen
909 * gprof.c: ignore __gnu_compiled symbols
910 * i386.h: dfine FOPEN_RB to "rb" for dos.
912 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
914 * Makefile.in (.m.c:): Added .SUFFIXES : .m
915 so flat_bl.c would make from flat_bl.m file.
917 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
919 * Makefile.in (install-info): Check for gprof.info in build dir,
920 fall back to srcdir. Depend on it.
922 * gprof.h (TRUE, FALSE): Always use undef before defining them.
924 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
926 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
927 makes (osf1) in which the value of MACHINE can not be changed.
928 * config/*.mt: Changed appropriately.
930 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
932 * gprof.c (getsymtab): Change nosyms to long. Rename
933 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
934 errors from bfd_get_symtab_upper_bound and
935 bfd_canonicalize_symtab.
937 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
939 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
942 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
944 * Makefile.in: Avoid bug in hpux sed.
946 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
948 * gprof.texi (Invoking): add text about -v flag
950 * gprof.1: add text about -v flag
952 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
954 * gprof.c (VERSION): defined a version macro, print the value
955 when the -v option is used
957 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
959 * Makefile.in: Install correctly.
961 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
963 * gprof.c (main): Get whoami from argv, instead of hardcoding.
964 Use it in usage message. Split usage message to fit in 80 cols.
966 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
968 * Makefile.in: Undo 15 June change.
970 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
972 * gmon.h, gprof.h: structs of chars used to hold external
974 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
977 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
979 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
981 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
983 * Makefile.in: remove parentdir support
985 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
987 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
988 * configure.in: No longer need to configure to get sysdep.h.
990 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
992 * Makefile.in (install): should not depend on install-info
994 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
996 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
998 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
1000 * M Makefile.in: Add -g to CFLAGS.
1001 Ads LDFLAGS and use in place of CFLAGS where appropriate.
1002 * configure.in: Make a sysdep.hlink in the same way other
1003 bfd-based directories do.
1004 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
1006 * gprof.h: #include sysdep.h instead of a bunch of stuff.
1007 * gprof.c (main): Fix typo gproff->gprof.
1009 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1011 * gprof.texi: add INFO-DIR-ENTRY
1013 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1015 * Makefile.in: add installcheck target
1017 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
1019 * gprof.c (funcsymbol): Invert test for aflag.
1021 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
1023 * printgprof (xmalloc, xrealloc): Cast results of malloc
1026 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
1028 * Makefile.in: created info, install-info, dvi
1030 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1032 * Makefile.in: fix install rule for $(PROG)
1034 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
1036 * gprof.1: updated SYNOPSIS to match actual behavior.
1038 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
1040 * gen-c-prog.awk: New awk script, lightly changed from
1041 previously deleted make-c-prog.awk. Converts a text file
1042 to a c function that prints that text.
1043 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
1044 Inputs to gen-c-prog.awk, containing text describing
1046 * blurbs.c: Removed. Use *_bl.c instead.
1047 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1048 from *_bl.m files. Also, improve *clean rules.
1049 * printgprof.c (printgprof): Usw new function names from *_bl.c.
1052 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
1054 * gprof.h, gprof.c, printfgprof.c: Add support for two
1055 output styles: The default is similar to the old FSF gprof,
1056 while -T sets the variable bsd_style_output, which causes
1057 output matching Berkeley's gprof. The biggest differences
1058 are that with the FSF style output, the flat profile comes
1059 before the call graph; numbers come before explanations;
1060 and there is less gratuitous white space.
1061 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
1062 variable causes discarding of initial underscores when
1063 printing symbol names. It is set unless there is a "main"
1064 symbol (without an underscore).
1065 * printfgprof.c: New function printnameonly(), called
1066 by printname(). It handles stripping of initial '_',
1067 as well as C++ name-demangling.
1068 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
1069 It is just as convenient to edit blurbs.c directly.
1070 * Makefile.in: Removed rule for making blurbs.c.
1071 * blurbs.c: This is now a true source file (as opposed
1072 to being generated from gprof.callg and gprof.flat).
1073 Change style to use one long string literal, instead of
