 718
 719         * Makefile.in: Add dependecies for $(OBJS) on header files.
 720
 721         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 722         style output format to make it consistent.
 723         * dummy.c (find_call): Fix typo in error message.
 724
 725 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 726
 727         * Makefile.in (maintainer-clean): New target, synonym for
 728         realclean.
 729
 730 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 731
 732         * Makefile.in (install): Don't install in $(tooldir).
 733
 734 Fri Aug 25 15:30:05 1995  Ken Raeburn  <raeburn@cygnus.com>
 735
 736         NS32K changes from Ian Dall:
 737         * configure.in: Use ns32k, not ns532.
 738         * ns532.c: Include symtab.h.
 739         (find_call): Renamed from findcall.  Print a message.
 740         * ns532.h: Remove dummy.h comments.
 741
 742 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 743
 744         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 745         that we're using autoconf.
 746
 747 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 748
 749         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
 750         to proper type of "unsigned int *".
 751
 752 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 753
 754         * configure.in: Use changequote around use of [].
 755
 756 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 757
 758         * Makefile.in (distclean, realclean): Remove config.cache and
 759           config.log.
 760
 761 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 762
 763         * Makefile.in (Makefile): Added config.status to dependency list.
 764           (config.status): New target.
 765           (SHELL): New definition.
 766
 767 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 768
 769         * Makefile.in (install): Depend on "all".
 770
 771 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 772
 773         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 774         to match configure script.
 775
 776 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 777
 778         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 779           comment emitted by this script to gen-c-prog.awk.
 780
 781         * Makefile.in, configure.in: Converted to use autoconf.
 782         * configure: New file, generated with autoconf 2.3.
 783         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 784           mt-tahoe, mt-vax}: Removed.
 785
 786 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 787
 788         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 789
 790         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 791
 792         * All *.c: More cleanup towards GNU format.
 793
 794         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 795         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 796         that bfd_vma is only guaranteed to be at least as big as a pointer.
 797
 798         (GMON_Record_tag): added explicit enumeration values to ensure
 799         compatibility across compilers.
 800
 801         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 802         sizeof(char*).
 803
 804 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 805
 806         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 807         of constructs GNU indent couldn't handle.  Block comments not yet
 808         rewritten in GNU format.
 809
 810         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 811         binutils release.
 812
 813 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 814
 815         * symtab.c (symtab_finalize): ensure globals symbols really
 816         are favored over static ones---even if their name looks less
 817         preferable; this is important for HP-UX; for example, there
 818         is a static label Ltext_something that aliases the global
 819         symbol _start
 820
 821         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 822         output only; also, auto-scaling is now performed based on
 823         per-call, rather than total execution time, which is what it was
 824         meant to be.
 825
 826         * gprof.h (File_Format): new type.
 827
 828         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 829         sync with Cygnus version numbers though...
 830
 831         (long_options): renamed --gmon-info to --file-info, --width added,
 832         renamed --old-file-format to --file-format
 833         (main): dito; also added support to read prof files, but as
 834         mon_out_read() is not implemented, it's #ifdef'd out for now
 835
 836         (usage): update to reflect new options.
 837
 838         * gmon_io.c: replaced "old_file_format" by more general
 839         "file_format" option
 840
 841         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 842
 843         * core.c (core_sym_class): added back check for __gnu_compiled and
 844         ___gnu_compiled for the benefit of systems without
 845         bfd_find_nearest_line() support
 846
 847         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 848         with section-relative addresses
 849
 850         (core_create_function_syms): get_src_info() calls are currently
 851         enabled for OSF/1 only.  It appears to work allright for SunOS
 852         4.1.x as well, but on SPARCs it gets painfully slow with the
 853         current implementation of aout_32_find_nearest_line();
 854         unfortunately, this means that static functions will not have their
 855         filename printed in the call-graph function index; line-level
 856         profiling should still work, but requires some patience
 857
 858         * cg_print.c (cg_print_index): sanitised printing of index when
 859         using FSF-style output; in particular, output width is now controlled
 860         via option --width and the function tries hard to keep columns
 861         aligned even in the presence of (occasional) long names
 862
 863         * NOTES: a first shot at updating the documentation.
 864
 865 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 866
 867         * core.c (core_create_function_syms): fixed computation of min_vma
 868         and max_vma.
 869
 870         * *.c: removed rcsid.
 871
 872 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 873
 874         * Lots of changes from David Mosberger-Tang:
 875
 876         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 877
 878         * gprof.c (main): put parentheses around & within &&.
 879
 880         * basic_blocks.c (bb_read_rec): print warning message (once) when
 881         ignoring basic-block execution counts.
 882
 883         * source.c (source_file_lookup_name): corrected second argument to
 884         strcmp().
 885
 886         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 887         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 888
 889         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 890         supported both for old and new (versioned) gmon.out files.  Old
 891         files are identified as version 0.
 892
 893         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 894         long (instead of 4) because that is what OSF/1 v3.0 uses.
 895
 896         * core.c: minor fixes and debugging info changes.
 897
 898         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 899
 900         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 901         name of the text-section under HP-UX).
 902
 903         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 904         points one past the last sampling bin, so hist_scale should be
 905         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 906         hist_num_bins - 1".
 907
 908         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 909         hist_num_bins.
 910
 911         * configure.in: added alpha-*-*) for per-target config.
 912
 913         * alpha.c, alpha.h: created.
 914
 915         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 916
 917         * core.c (core_create_function_syms, core_create_line_syms):
 918         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 919         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 920         addr) continues to guarantee not to return 0 on any address.  It
 921         also avoids incorrectly crediting the first/last symbol in the
 922         text-space.
 923
 924         * core.c (core_create_line_syms): always create function symbols
 925         first, then merge in line symbols; this is so that if parts of the
 926         program were compiled without -g, function-level symbols are
 927         available still.
 928
 929         * utils.c (print_name_only): support for print_path added.
 930
 931         * symtab.c (cmp_addr): also use is_func flag in comparison.
 932         (symtab_finalize): return immediately when table empty; now
 933         more careful about getting rid of the right duplicate symbol.
 934
 935         * sparc.c (find_call): many fixes---this function was rather
 936         botched in binutils-2.4 already; it should work again.
 937
 938         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 939         not good to rely on get_src_info() to return distinct string
 940         pointers).
 941
 942         * search_list.c (search_list_append): added cast for xmalloc().
 943
 944         * hist.c: added explicit initialization to some of the global
 945         variables; fixed SItab (scales were off by a factor of 10).
 946
 947         * hist.h: include of bfd.h added.
 948
 949         * gprof.c, gprof.h (print_path): added.
 950
 951         * gprof.h (MAX): fixed.
 952
 953         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 954
 955         * gmon_io.c: added some casts to (long) so we can always print as %lx
 956
 957         * core.c (core_get_text_space): fixed to make it work.
 958
 959         * cg_print.c (cg_print_index): added support for print_path option.
 960
 961         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 962
 963         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 964         as some compilers complain (e.g., DEC's OSF/1 compiler)
 965
 966         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 967         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 968
 969         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 970
 971         * gprof.c: added "_mcount" to default_excluded_list.
 972         (main): if output_style==0 and there is either a histogram or a
 973         call-graph, always generate flat and call-graph, no matter what
 974         line_granularity is set to.
 975
 976         * source.c (source_file_lookup_name): if searching for sf->name
 977         fails, try again with filename obtained after stripping off any
 978         partial path from sf->name.
 979
 980         * gprof.h (SRCDEBUG): added.
 981
 982         * search_list.c (search_list_append): directories were added in wrong
 983         order.
 984
 985         * reimplemented selection mechanism from ground up; it is now possible
 986         to accurately control what gets included/excluded in each of the
 987         output styles;  a "symbol-specification" (spec) is the basic means
 988         to select a set of symbols; a spec has the syntax:
 989
 990           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 991           arc == spec/spec.
 992
 993         any of the terminal symbols can be empty, in which case they
 994         match anything (wildcards).  NAME is interpreted as a FILENAME
 995         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 996         with a digit, and as FUNCNAME otherwise.
 997
 998         For example, to get a call-graph display that ignores arcs
 999         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
1000         show only arcs into bar() (no matter what the caller),
1001         you'd say "--graph=/bar"; and to get a call-graph without
1002         any arc info, you'd say "--graph=/";  similarly, to
1003         get a flat profile without mcount, you'd say "--no-flat=mcount"
1004         and to get a flat profile that shows includes all functions
1005         you'd say "--flat=""" (i.e., an empty spec)
1006
1007         * hist.c (hist_print): top_time wasn't initialized to 0.0.
1008
1009         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1010
1011         * gmon_out.h: all headers now declared in terms of characters
1012           to avoid getting into trouble with different compilers introducing
1013           different amount of padding; the code already accessed the fields
1014           through bfd functions, so that didn't have to change.
1015
1016         * hist.c (hist_read_rec, hist_write_rec): added support for
1017           collection pc histograms measuring quantities other than time;
1018           the histogram header now includes a field that specifies the
1019           dimension of the quantity measured by the histogram bins
1020           (normally, this is "seconds", but other meaningful dimensions
1021            include such things as "I-cache misses", "instruction issue stalls"
1022            etc.); there is also a field to specify a one-character
1023           abbreviation for the dimension; in the case of time, this would
1024           be 's'; in most other cases it probably would be '1' (not a physical
1025           dimension).
1026
1027         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1028
1029         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
1030           has become old_file_version; gmon_io.c now always supports old-style
1031           gmon.out files; it first tries to read gmon.out as a new version
1032           file, if that fails, it tries to read it in the old format;
1033           although not very likely, it is possible for gprof to mistake an
1034           old-style file as a new one (the first 4 bytes would have to
1035           be "gmon"---including the trailing '\0'); in that case, it is
1036           necessary to specify --old-file-version
1037
1038         * gprof.h: removed dependency on SYSV; the code now always uses
1039           strrchr(), memset(), and memcpy() and does not include either
1040           of string.h or strings.h; this should make gprof compile on
1041           any (Unix) system without configuration (per suggestion of
1042           raeburn@cygnus.com)
1043
1044         * gprof.c (usage): fixed location of --new-file-format option.
1045
1046         * cg_arcs.c (propagate_flags): fixed typo in declaration.
1047
1048         * flat_bl.m: removed formfeed at end of file; the form-feed
1049           is now printed cg_print.c only when necessary.
1050
1051         * major rewrite of gprof---too many changes to mention all of
1052           them.  new features:
1053
1054         + -l now requests profiling at the line level (as opposed
1055           to function level); in this mode, gprof creates a "symbol"
1056           (aka name-list entry) for each line of source code, instead
1057            of one per function)
1058
1059         + support for a new gmon.out file format; the new format
1060           consists of a header with a magic and a version number,
1061           followed by a sequence of profile data; profile data
1062           can any of: (a) PC histogram, (b) call-graph arcs, or
1063           (c) basic-block execution counts; the version number makes
1064           it possible to extend gmon.out in a backwards compatible
1065           fashion
1066
1067         + support for tcov style annotated output: if the gmon.out file
1068           contains basic-block execution counts, the user can request
1069           the generation of annotated source files, much like Sun's
1070           tcov used to do
1071
1072         + long options
1073
1074         + new scheme to suppress symbols that aren't function names
1075           (e.g., avoids mistaking a goto label as a function)
1076
1077         + reorganized source code to make it more managable; as a
1078           side effect, gprof now compiles cleanly with "gcc -Wall"

1081
1082         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
1083         final cross-check to determine whether a static symbol should be
1084         considered as a function-name.
1085
1086         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1087
1088         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
1089         stdin; this is useful if you wanna keep gmon.out files compressed;
1090         this way you can "gzcat" the compressed file into gprof.
1091
1092         * gprof.c: flag_min_count now initialized with 1 instead of 0.
1093
1094         * basic_blocks.c (bb_annotate_source): added support for creating
1095         .tcov files when option flag_annotate_make_files is TRUE.
1096         (annotate_with_count): all counts less than the minimum count
1097         specified by -m are now annotated with hash-marks.
1098
1099         * gprof.c (main): -A is now followed by a string of option chars.
1100
1101         * basic_blocks.c (annotate_with_count): replaced b->count with
1102         cnt.
1103
1104         * source.c: flag_annotate_source replaced by source_lock_map.
1105
1106         * source.h: source_lock_map added.
1107
1108         * gprof.c (main): new command-line syntax: -S simply specifies
1109         which source-files user is interested in; -A requests annotated
1110         source files and -AA requests that all lines in a source file
1111         are annotated.
1112
1113         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1114
1115         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
1116
1117         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
1118         so s_lowpc etc. get declared.
1119
1120         * arcs.h (doarcs): created.
1121
1122         * arcs.c: reordered static functions such that they get defined
1123         before use.
1124
1125         * gprof.c (main): added options:
1126            -A: request annotation of all source lines (with -S)
1127            -m: minimum execution count (with default basic-block display)
1128            -N: force new file format (only if BSD_COMPATIBLE is defined)
1129            -S: annotate source file
1130            -t: set table length (with -S)
1131
1132         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
1133         source.o time_hist.o
1134

1136
1137         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
1138         on the fact being able to store a long in a double without loss of
1139         precision; this does not hold on machines with 64 bit longs and 64
1140         bit doubles.

1145         greater than 0.0.  Suggested by Harold Assink
1146         <carlo@sg.tn.tudelft.nl>.

1149
1150         * printgprof.c (printprof): Use free, not cfree.
1151         (printgprof, printindex): Ditto.

1159
1160         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
1161         __gnu_compiled, for the benefit of systems which add a leading
1162         underscore.

1175         Allows compilation with -Dregister= for debugging.
1176
1177         * configure.in: Add ns532 support.

1196
1197         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
1198         so flat_bl.c would make from flat_bl.m file.
1199

1208
1209         * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
1210         makes (osf1) in which the value of MACHINE can not be changed.
1211         * config/*.mt: Changed appropriately.
1212
1213 Wed Mar 30 16:12:40 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

1216         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
1217         errors from bfd_get_symtab_upper_bound and
1218         bfd_canonicalize_symtab.

1254
1255         * gmon.h, gprof.h: structs of chars used to hold external

1316
1317 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
1318
1319         * gprof.1: updated SYNOPSIS to match actual behavior.
1320
1321 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
1322
1323         * gen-c-prog.awk:  New awk script, lightly changed from
1324         previously deleted make-c-prog.awk.  Converts a text file
1325         to a c function that prints that text.
1326         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
1327         Inputs to gen-c-prog.awk, containing text describing
1328         gprof output.
1329         * blurbs.c:  Removed.  Use *_bl.c instead.
1330         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1331         from *_bl.m files.  Also, improve *clean rules.
1332         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
1333
1334
1335 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
1336
1337         * gprof.h, gprof.c, printfgprof.c:  Add support for two
1338         output styles:  The default is similar to the old FSF gprof,
1339         while -T sets the variable bsd_style_output, which causes
1340         output matching Berkeley's gprof.  The biggest differences
1341         are that with the FSF style output, the flat profile comes
1342         before the call graph; numbers come before explanations;
1343         and there is less gratuitous white space.
1344         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
1345         variable causes discarding of initial underscores when
1346         printing symbol names.  It is set unless there is a "main"
1347         symbol (without an underscore).
1348         * printfgprof.c:  New function printnameonly(), called
1349         by printname().  It handles stripping of initial '_',
1350         as well as C++ name-demangling.
1351         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
1352         It is just as convenient to edit blurbs.c directly.
1353         * Makefile.in:  Removed rule for making blurbs.c.
1354         * blurbs.c:  This is now a true source file (as opposed
1355         to being generated from gprof.callg and gprof.flat).
1356         Change style to use one long string literal, instead of
1357         one literal per output line.  Add FSF-style blurb for call graph.
1358
1359 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
1360
1361         * Makefile.in: always create installation directories.

1363 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
1364

1368
1369         * Makefile.in:  removed installation of the now useless
1370         call.{flag,callg} files.
1371
1372         * gprof.1: now uses the standard man macros instead of the new BSD
1373         mandoc macros.
1374
1375 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
1376
1377         * configure.in:  Remove host section, expand target section.
1378         * config/mt-{tahoe,vax}:  Add, to match existing support files.
1379         * config/tmake-*:  Remove leftover crud.
1380
1381         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
1382         * make-c-prog.awk:  which processes text files into C programs.
1383         * printgprof.c (flatprofheader, gprofheader):  Call new functions
1384         to print blurbs.
1385         (printblurb):  Remove.
1386         * Makefile.in:  Infrastructure to build blurbs.
1387         * pathnames.h:  has been removed.  Gprof now has no filename
1388         dependencies in it.
1389         * gprof.c:  Lint.

1399 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
1400
1401         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
1402         help in debugging the problem (with -DDEBUG)
1403         * gprof.c: symbol values are now real values, don't add the vma
1404         anymore. (done for solaris; should verify this on other platforms)
1405         * ChangeLog: created.
