 712         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
 713         to proper type of "unsigned int *".
 714
 715 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 716
 717         * configure.in: Use changequote around use of [].
 718
 719 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 720
 721         * Makefile.in (distclean, realclean): Remove config.cache and
 722           config.log.
 723
 724 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 725
 726         * Makefile.in (Makefile): Added config.status to dependency list.
 727           (config.status): New target.
 728           (SHELL): New definition.
 729
 730 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 731
 732         * Makefile.in (install): Depend on "all".
 733
 734 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 735
 736         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 737         to match configure script.
 738
 739 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 740
 741         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 742           comment emitted by this script to gen-c-prog.awk.
 743
 744         * Makefile.in, configure.in: Converted to use autoconf.
 745         * configure: New file, generated with autoconf 2.3.
 746         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 747           mt-tahoe, mt-vax}: Removed.
 748
 749 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 750
 751         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 752
 753         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 754
 755         * All *.c: More cleanup towards GNU format.
 756
 757         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 758         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 759         that bfd_vma is only guaranteed to be at least as big as a pointer.
 760
 761         (GMON_Record_tag): added explicit enumeration values to ensure
 762         compatibility across compilers.
 763
 764         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 765         sizeof(char*).
 766
 767 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 768
 769         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 770         of constructs GNU indent couldn't handle.  Block comments not yet
 771         rewritten in GNU format.
 772
 773         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 774         binutils release.
 775
 776 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 777
 778         * symtab.c (symtab_finalize): ensure globals symbols really
 779         are favored over static ones---even if their name looks less
 780         preferable; this is important for HP-UX; for example, there
 781         is a static label Ltext_something that aliases the global
 782         symbol _start
 783
 784         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 785         output only; also, auto-scaling is now performed based on
 786         per-call, rather than total execution time, which is what it was
 787         meant to be.
 788
 789         * gprof.h (File_Format): new type.
 790
 791         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 792         sync with Cygnus version numbers though...
 793
 794         (long_options): renamed --gmon-info to --file-info, --width added,
 795         renamed --old-file-format to --file-format
 796         (main): dito; also added support to read prof files, but as
 797         mon_out_read() is not implemented, it's #ifdef'd out for now
 798
 799         (usage): update to reflect new options.
 800
 801         * gmon_io.c: replaced "old_file_format" by more general
 802         "file_format" option
 803
 804         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 805
 806         * core.c (core_sym_class): added back check for __gnu_compiled and
 807         ___gnu_compiled for the benefit of systems without
 808         bfd_find_nearest_line() support
 809
 810         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 811         with section-relative addresses
 812
 813         (core_create_function_syms): get_src_info() calls are currently
 814         enabled for OSF/1 only.  It appears to work allright for SunOS
 815         4.1.x as well, but on SPARCs it gets painfully slow with the
 816         current implementation of aout_32_find_nearest_line();
 817         unfortunately, this means that static functions will not have their
 818         filename printed in the call-graph function index; line-level
 819         profiling should still work, but requires some patience
 820
 821         * cg_print.c (cg_print_index): sanitised printing of index when
 822         using FSF-style output; in particular, output width is now controlled
 823         via option --width and the function tries hard to keep columns
 824         aligned even in the presence of (occasional) long names
 825
 826         * NOTES: a first shot at updating the documentation.
 827
 828 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 829
 830         * core.c (core_create_function_syms): fixed computation of min_vma
 831         and max_vma.
 832
 833         * *.c: removed rcsid.
 834
 835 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 836
 837         * Lots of changes from David Mosberger-Tang:
 838
 839         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 840
 841         * gprof.c (main): put parentheses around & within &&.
 842
 843         * basic_blocks.c (bb_read_rec): print warning message (once) when
 844         ignoring basic-block execution counts.
 845
 846         * source.c (source_file_lookup_name): corrected second argument to
 847         strcmp().
 848
 849         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 850         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 851
 852         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 853         supported both for old and new (versioned) gmon.out files.  Old
 854         files are identified as version 0.
 855
 856         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 857         long (instead of 4) because that is what OSF/1 v3.0 uses.
 858
 859         * core.c: minor fixes and debugging info changes.
 860
 861         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 862
 863         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 864         name of the text-section under HP-UX).
 865
 866         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 867         points one past the last sampling bin, so hist_scale should be
 868         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 869         hist_num_bins - 1".
 870
 871         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 872         hist_num_bins.
 873
 874         * configure.in: added alpha-*-*) for per-target config.
 875
 876         * alpha.c, alpha.h: created.
 877
 878         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 879
 880         * core.c (core_create_function_syms, core_create_line_syms):
 881         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 882         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 883         addr) continues to guarantee not to return 0 on any address.  It
 884         also avoids incorrectly crediting the first/last symbol in the
 885         text-space.
 886
 887         * core.c (core_create_line_syms): always create function symbols
 888         first, then merge in line symbols; this is so that if parts of the
 889         program were compiled without -g, function-level symbols are
 890         available still.
 891
 892         * utils.c (print_name_only): support for print_path added.
 893
 894         * symtab.c (cmp_addr): also use is_func flag in comparison.
 895         (symtab_finalize): return immediately when table empty; now
 896         more careful about getting rid of the right duplicate symbol.
 897
 898         * sparc.c (find_call): many fixes---this function was rather
 899         botched in binutils-2.4 already; it should work again.
 900
 901         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 902         not good to rely on get_src_info() to return distinct string
 903         pointers).
 904
 905         * search_list.c (search_list_append): added cast for xmalloc().
 906
 907         * hist.c: added explicit initialization to some of the global
 908         variables; fixed SItab (scales were off by a factor of 10).
 909
 910         * hist.h: include of bfd.h added.
 911
 912         * gprof.c, gprof.h (print_path): added.
 913
 914         * gprof.h (MAX): fixed.
 915
 916         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 917
 918         * gmon_io.c: added some casts to (long) so we can always print as %lx
 919
 920         * core.c (core_get_text_space): fixed to make it work.
 921
 922         * cg_print.c (cg_print_index): added support for print_path option.
 923
 924         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 925
 926         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 927         as some compilers complain (e.g., DEC's OSF/1 compiler)
 928
 929         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 930         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 931
 932         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 933
 934         * gprof.c: added "_mcount" to default_excluded_list.
 935         (main): if output_style==0 and there is either a histogram or a
 936         call-graph, always generate flat and call-graph, no matter what
 937         line_granularity is set to.
 938
 939         * source.c (source_file_lookup_name): if searching for sf->name
 940         fails, try again with filename obtained after stripping off any
 941         partial path from sf->name.
 942
 943         * gprof.h (SRCDEBUG): added.
 944
 945         * search_list.c (search_list_append): directories were added in wrong
 946         order.
 947
 948         * reimplemented selection mechanism from ground up; it is now possible
 949         to accurately control what gets included/excluded in each of the
 950         output styles;  a "symbol-specification" (spec) is the basic means
 951         to select a set of symbols; a spec has the syntax:
 952
 953           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 954           arc == spec/spec.
 955
 956         any of the terminal symbols can be empty, in which case they
 957         match anything (wildcards).  NAME is interpreted as a FILENAME
 958         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 959         with a digit, and as FUNCNAME otherwise.
 960
 961         For example, to get a call-graph display that ignores arcs
 962         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 963         show only arcs into bar() (no matter what the caller),
 964         you'd say "--graph=/bar"; and to get a call-graph without
 965         any arc info, you'd say "--graph=/";  similarly, to
 966         get a flat profile without mcount, you'd say "--no-flat=mcount"
 967         and to get a flat profile that shows includes all functions
 968         you'd say "--flat=""" (i.e., an empty spec)
 969
 970         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 971
 972         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 973
 974         * gmon_out.h: all headers now declared in terms of characters
 975           to avoid getting into trouble with different compilers introducing
 976           different amount of padding; the code already accessed the fields
 977           through bfd functions, so that didn't have to change.
 978
 979         * hist.c (hist_read_rec, hist_write_rec): added support for
 980           collection pc histograms measuring quantities other than time;
 981           the histogram header now includes a field that specifies the
 982           dimension of the quantity measured by the histogram bins
 983           (normally, this is "seconds", but other meaningful dimensions
 984            include such things as "I-cache misses", "instruction issue stalls"
 985            etc.); there is also a field to specify a one-character
 986           abbreviation for the dimension; in the case of time, this would
 987           be 's'; in most other cases it probably would be '1' (not a physical
 988           dimension).
 989
 990         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 991
 992         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 993           has become old_file_version; gmon_io.c now always supports old-style
 994           gmon.out files; it first tries to read gmon.out as a new version
 995           file, if that fails, it tries to read it in the old format;
 996           although not very likely, it is possible for gprof to mistake an
 997           old-style file as a new one (the first 4 bytes would have to
 998           be "gmon"---including the trailing '\0'); in that case, it is
 999           necessary to specify --old-file-version
1000
1001         * gprof.h: removed dependency on SYSV; the code now always uses
1002           strrchr(), memset(), and memcpy() and does not include either
1003           of string.h or strings.h; this should make gprof compile on
1004           any (Unix) system without configuration (per suggestion of
1005           raeburn@cygnus.com)
1006
1007         * gprof.c (usage): fixed location of --new-file-format option.
1008
1009         * cg_arcs.c (propagate_flags): fixed typo in declaration.
1010
1011         * flat_bl.m: removed formfeed at end of file; the form-feed
1012           is now printed cg_print.c only when necessary.
1013
1014         * major rewrite of gprof---too many changes to mention all of
1015           them.  new features:
1016
1017         + -l now requests profiling at the line level (as opposed
1018           to function level); in this mode, gprof creates a "symbol"
1019           (aka name-list entry) for each line of source code, instead
1020            of one per function)
1021
1022         + support for a new gmon.out file format; the new format
1023           consists of a header with a magic and a version number,
1024           followed by a sequence of profile data; profile data
1025           can any of: (a) PC histogram, (b) call-graph arcs, or
1026           (c) basic-block execution counts; the version number makes
1027           it possible to extend gmon.out in a backwards compatible
1028           fashion
1029
1030         + support for tcov style annotated output: if the gmon.out file
1031           contains basic-block execution counts, the user can request
1032           the generation of annotated source files, much like Sun's
1033           tcov used to do
1034
1035         + long options
1036
1037         + new scheme to suppress symbols that aren't function names
1038           (e.g., avoids mistaking a goto label as a function)
1039
1040         + reorganized source code to make it more managable; as a
1041           side effect, gprof now compiles cleanly with "gcc -Wall"
1042
1043         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1044
1045         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
1046         final cross-check to determine whether a static symbol should be
1047         considered as a function-name.
1048
1049         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1050
1051         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
1052         stdin; this is useful if you wanna keep gmon.out files compressed;
1053         this way you can "gzcat" the compressed file into gprof.
1054
1055         * gprof.c: flag_min_count now initialized with 1 instead of 0.
1056
1057         * basic_blocks.c (bb_annotate_source): added support for creating
1058         .tcov files when option flag_annotate_make_files is TRUE.
1059         (annotate_with_count): all counts less than the minimum count
1060         specified by -m are now annotated with hash-marks.
1061
1062         * gprof.c (main): -A is now followed by a string of option chars.
1063
1064         * basic_blocks.c (annotate_with_count): replaced b->count with
1065         cnt.

1069         * source.h: source_lock_map added.
1070
1071         * gprof.c (main): new command-line syntax: -S simply specifies
1072         which source-files user is interested in; -A requests annotated
1073         source files and -AA requests that all lines in a source file
1074         are annotated.

1076         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1077
1078         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
1079
1080         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
1081         so s_lowpc etc. get declared.
1082
1083         * arcs.h (doarcs): created.
1084
1085         * arcs.c: reordered static functions such that they get defined

1099
1100         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
1101         on the fact being able to store a long in a double without loss of
1102         precision; this does not hold on machines with 64 bit longs and 64
1103         bit doubles.

1279
1280 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
1281
1282         * gprof.1: updated SYNOPSIS to match actual behavior.
1283
1284 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
1285
1286         * gen-c-prog.awk:  New awk script, lightly changed from
1287         previously deleted make-c-prog.awk.  Converts a text file
1288         to a c function that prints that text.
1289         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
1290         Inputs to gen-c-prog.awk, containing text describing
1291         gprof output.
1292         * blurbs.c:  Removed.  Use *_bl.c instead.
1293         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1294         from *_bl.m files.  Also, improve *clean rules.
1295         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
1296
1297
1298 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
1299
1300         * gprof.h, gprof.c, printfgprof.c:  Add support for two
1301         output styles:  The default is similar to the old FSF gprof,
1302         while -T sets the variable bsd_style_output, which causes
1303         output matching Berkeley's gprof.  The biggest differences
1304         are that with the FSF style output, the flat profile comes
1305         before the call graph; numbers come before explanations;
1306         and there is less gratuitous white space.
1307         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
1308         variable causes discarding of initial underscores when
1309         printing symbol names.  It is set unless there is a "main"
1310         symbol (without an underscore).
1311         * printfgprof.c:  New function printnameonly(), called
1312         by printname().  It handles stripping of initial '_',
1313         as well as C++ name-demangling.
1314         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
1315         It is just as convenient to edit blurbs.c directly.
1316         * Makefile.in:  Removed rule for making blurbs.c.
1317         * blurbs.c:  This is now a true source file (as opposed
1318         to being generated from gprof.callg and gprof.flat).
1319         Change style to use one long string literal, instead of
1320         one literal per output line.  Add FSF-style blurb for call graph.
1321
1322 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
1323
1324         * Makefile.in: always create installation directories.

1332         * Makefile.in:  removed installation of the now useless
1333         call.{flag,callg} files.
1334
1335         * gprof.1: now uses the standard man macros instead of the new BSD
1336         mandoc macros.
1337
1338 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
1339
1340         * configure.in:  Remove host section, expand target section.
1341         * config/mt-{tahoe,vax}:  Add, to match existing support files.
1342         * config/tmake-*:  Remove leftover crud.
1343
1344         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
1345         * make-c-prog.awk:  which processes text files into C programs.
1346         * printgprof.c (flatprofheader, gprofheader):  Call new functions
1347         to print blurbs.
1348         (printblurb):  Remove.
1349         * Makefile.in:  Infrastructure to build blurbs.
1350         * pathnames.h:  has been removed.  Gprof now has no filename
1351         dependencies in it.
1352         * gprof.c:  Lint.

1361
1362 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
1363
1364         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
1365         help in debugging the problem (with -DDEBUG)
1366         * gprof.c: symbol values are now real values, don't add the vma
1367         anymore. (done for solaris; should verify this on other platforms)
1368         * ChangeLog: created.
