 716         function ordering.
 717         (cg_print_file_ordering): Likewise for ordering .o files.
 718         (order_and_dump_functions_by_arcs): Helper function for function
 719         and object file ordering code.
 720
 721 Sun Dec 24 21:32:27 1995  Jeffrey A Law  (law@cygnus.com)
 722
 723         * core.c (core_sym_class): Ignore symbols without BSF_FUNCTION
 724         set if ignore_non_function is set.
 725         * gprof.h (ignore_non_functions): Declare.
 726         * gprof.c (ignore_non_functions): Define.
 727         (long_options): Add "ignore-non-functions".
 728         (usage): Add new options.
 729         (main): Recognize "-D" and "--ignore-non-functions" option.

 731 Tue Nov 21 13:24:39 1995  Ken Raeburn  <raeburn@cygnus.com>
 732
 733         * Makefile.in (.m.c): Strip out directory name from function
 734         name.
 735
 736         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 737         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 738         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 739
 740         * vax.c: Don't include vax.h here.
 741

 751
 752         * Makefile.in (TAGS): New target.
 753
 754 Wed Nov  1 12:51:21 1995  Per Bothner  <bothner@kalessin.cygnus.com>
 755
 756         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 757         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 758         on info).
 759
 760 Wed Nov  1 15:23:15 1995  Manfred Hollstein KS/EF4A 60/1F/110 #40283  <manfred@lts.sel.alcatel.de>
 761
 762         * sym_ids.c: Include <ctype.h>.

 764 Wed Oct 25 13:24:31 1995  Per Bothner  <bothner@kalessin.cygnus.com>
 765
 766         * Makefile.in (diststuff):  Also make info.
 767         (mostlyclean):  Don't remove gprof.info*.
 768         (maintainer-clean realclean):  Also remove *.info*.

 772         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 773
 774         * Makefile.in: Add dependecies for $(OBJS) on header files.
 775
 776         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 777         style output format to make it consistent.
 778         * dummy.c (find_call): Fix typo in error message.
 779
 780 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 781
 782         * Makefile.in (maintainer-clean): New target, synonym for
 783         realclean.
 784
 785 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 786
 787         * Makefile.in (install): Don't install in $(tooldir).

 789 Fri Aug 25 15:30:05 1995  Ken Raeburn  <raeburn@cygnus.com>
 790
 791         NS32K changes from Ian Dall:
 792         * configure.in: Use ns32k, not ns532.
 793         * ns532.c: Include symtab.h.
 794         (find_call): Renamed from findcall.  Print a message.

 796
 797 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 798
 799         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 800         that we're using autoconf.
 801
 802 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 803
 804         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
 805         to proper type of "unsigned int *".
 806
 807 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 808
 809         * configure.in: Use changequote around use of [].
 810
 811 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 812
 813         * Makefile.in (distclean, realclean): Remove config.cache and
 814           config.log.
 815
 816 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 817
 818         * Makefile.in (Makefile): Added config.status to dependency list.
 819           (config.status): New target.
 820           (SHELL): New definition.
 821
 822 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 823
 824         * Makefile.in (install): Depend on "all".
 825
 826 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 827
 828         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 829         to match configure script.
 830
 831 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 832
 833         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 834           comment emitted by this script to gen-c-prog.awk.
 835
 836         * Makefile.in, configure.in: Converted to use autoconf.
 837         * configure: New file, generated with autoconf 2.3.
 838         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 839           mt-tahoe, mt-vax}: Removed.
 840
 841 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 842
 843         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 844
 845         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 846
 847         * All *.c: More cleanup towards GNU format.
 848
 849         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 850         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 851         that bfd_vma is only guaranteed to be at least as big as a pointer.
 852
 853         (GMON_Record_tag): added explicit enumeration values to ensure
 854         compatibility across compilers.
 855
 856         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 857         sizeof(char*).
 858
 859 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 860
 861         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 862         of constructs GNU indent couldn't handle.  Block comments not yet
 863         rewritten in GNU format.
 864
 865         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 866         binutils release.
 867
 868 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 869
 870         * symtab.c (symtab_finalize): ensure globals symbols really
 871         are favored over static ones---even if their name looks less
 872         preferable; this is important for HP-UX; for example, there
 873         is a static label Ltext_something that aliases the global
 874         symbol _start
 875
 876         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 877         output only; also, auto-scaling is now performed based on
 878         per-call, rather than total execution time, which is what it was
 879         meant to be.
 880
 881         * gprof.h (File_Format): new type.
 882
 883         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 884         sync with Cygnus version numbers though...
 885
 886         (long_options): renamed --gmon-info to --file-info, --width added,
 887         renamed --old-file-format to --file-format
 888         (main): dito; also added support to read prof files, but as
 889         mon_out_read() is not implemented, it's #ifdef'd out for now
 890
 891         (usage): update to reflect new options.
 892
 893         * gmon_io.c: replaced "old_file_format" by more general
 894         "file_format" option
 895
 896         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 897
 898         * core.c (core_sym_class): added back check for __gnu_compiled and
 899         ___gnu_compiled for the benefit of systems without
 900         bfd_find_nearest_line() support
 901
 902         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 903         with section-relative addresses
 904
 905         (core_create_function_syms): get_src_info() calls are currently
 906         enabled for OSF/1 only.  It appears to work allright for SunOS
 907         4.1.x as well, but on SPARCs it gets painfully slow with the
 908         current implementation of aout_32_find_nearest_line();
 909         unfortunately, this means that static functions will not have their
 910         filename printed in the call-graph function index; line-level
 911         profiling should still work, but requires some patience
 912
 913         * cg_print.c (cg_print_index): sanitised printing of index when
 914         using FSF-style output; in particular, output width is now controlled
 915         via option --width and the function tries hard to keep columns
 916         aligned even in the presence of (occasional) long names
 917
 918         * NOTES: a first shot at updating the documentation.
 919
 920 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 921
 922         * core.c (core_create_function_syms): fixed computation of min_vma
 923         and max_vma.
 924
 925         * *.c: removed rcsid.
 926
 927 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 928
 929         * Lots of changes from David Mosberger-Tang:
 930
 931         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 932
 933         * gprof.c (main): put parentheses around & within &&.
 934
 935         * basic_blocks.c (bb_read_rec): print warning message (once) when
 936         ignoring basic-block execution counts.
 937
 938         * source.c (source_file_lookup_name): corrected second argument to
 939         strcmp().
 940
 941         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 942         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 943
 944         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 945         supported both for old and new (versioned) gmon.out files.  Old
 946         files are identified as version 0.
 947
 948         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 949         long (instead of 4) because that is what OSF/1 v3.0 uses.
 950
 951         * core.c: minor fixes and debugging info changes.
 952
 953         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 954
 955         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 956         name of the text-section under HP-UX).
 957
 958         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 959         points one past the last sampling bin, so hist_scale should be
 960         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 961         hist_num_bins - 1".
 962
 963         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 964         hist_num_bins.
 965
 966         * configure.in: added alpha-*-*) for per-target config.
 967
 968         * alpha.c, alpha.h: created.
 969
 970         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 971
 972         * core.c (core_create_function_syms, core_create_line_syms):
 973         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 974         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 975         addr) continues to guarantee not to return 0 on any address.  It
 976         also avoids incorrectly crediting the first/last symbol in the
 977         text-space.
 978
 979         * core.c (core_create_line_syms): always create function symbols
 980         first, then merge in line symbols; this is so that if parts of the
 981         program were compiled without -g, function-level symbols are
 982         available still.
 983
 984         * utils.c (print_name_only): support for print_path added.
 985
 986         * symtab.c (cmp_addr): also use is_func flag in comparison.
 987         (symtab_finalize): return immediately when table empty; now
 988         more careful about getting rid of the right duplicate symbol.
 989
 990         * sparc.c (find_call): many fixes---this function was rather
 991         botched in binutils-2.4 already; it should work again.
 992
 993         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 994         not good to rely on get_src_info() to return distinct string
 995         pointers).
 996
 997         * search_list.c (search_list_append): added cast for xmalloc().
 998
 999         * hist.c: added explicit initialization to some of the global
1000         variables; fixed SItab (scales were off by a factor of 10).
1001
1002         * hist.h: include of bfd.h added.
1003
1004         * gprof.c, gprof.h (print_path): added.
1005
1006         * gprof.h (MAX): fixed.
1007
1008         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
1009
1010         * gmon_io.c: added some casts to (long) so we can always print as %lx
1011
1012         * core.c (core_get_text_space): fixed to make it work.
1013
1014         * cg_print.c (cg_print_index): added support for print_path option.
1015
1016         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
1017
1018         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
1019         as some compilers complain (e.g., DEC's OSF/1 compiler)
1020
1021         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
1022         symtab.c: calls to memset() had 2nd and 3rd args reversed.
1023
1024         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1025
1026         * gprof.c: added "_mcount" to default_excluded_list.
1027         (main): if output_style==0 and there is either a histogram or a
1028         call-graph, always generate flat and call-graph, no matter what
1029         line_granularity is set to.
1030
1031         * source.c (source_file_lookup_name): if searching for sf->name
1032         fails, try again with filename obtained after stripping off any
1033         partial path from sf->name.
1034
1035         * gprof.h (SRCDEBUG): added.
1036
1037         * search_list.c (search_list_append): directories were added in wrong
1038         order.
1039
1040         * reimplemented selection mechanism from ground up; it is now possible
1041         to accurately control what gets included/excluded in each of the
1042         output styles;  a "symbol-specification" (spec) is the basic means
1043         to select a set of symbols; a spec has the syntax:
1044
1045           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
1046           arc == spec/spec.
1047
1048         any of the terminal symbols can be empty, in which case they
1049         match anything (wildcards).  NAME is interpreted as a FILENAME
1050         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
1051         with a digit, and as FUNCNAME otherwise.
1052
1053         For example, to get a call-graph display that ignores arcs
1054         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
1055         show only arcs into bar() (no matter what the caller),
1056         you'd say "--graph=/bar"; and to get a call-graph without
1057         any arc info, you'd say "--graph=/";  similarly, to
1058         get a flat profile without mcount, you'd say "--no-flat=mcount"
1059         and to get a flat profile that shows includes all functions
1060         you'd say "--flat=""" (i.e., an empty spec)
1061
1062         * hist.c (hist_print): top_time wasn't initialized to 0.0.
1063
1064         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1065
1066         * gmon_out.h: all headers now declared in terms of characters
1067           to avoid getting into trouble with different compilers introducing
1068           different amount of padding; the code already accessed the fields
1069           through bfd functions, so that didn't have to change.
1070
1071         * hist.c (hist_read_rec, hist_write_rec): added support for
1072           collection pc histograms measuring quantities other than time;
1073           the histogram header now includes a field that specifies the
1074           dimension of the quantity measured by the histogram bins
1075           (normally, this is "seconds", but other meaningful dimensions
1076            include such things as "I-cache misses", "instruction issue stalls"
1077            etc.); there is also a field to specify a one-character
1078           abbreviation for the dimension; in the case of time, this would
1079           be 's'; in most other cases it probably would be '1' (not a physical
1080           dimension).

1083
1084         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
1085           has become old_file_version; gmon_io.c now always supports old-style
1086           gmon.out files; it first tries to read gmon.out as a new version
1087           file, if that fails, it tries to read it in the old format;
1088           although not very likely, it is possible for gprof to mistake an
1089           old-style file as a new one (the first 4 bytes would have to
1090           be "gmon"---including the trailing '\0'); in that case, it is
1091           necessary to specify --old-file-version
1092
1093         * gprof.h: removed dependency on SYSV; the code now always uses
1094           strrchr(), memset(), and memcpy() and does not include either
1095           of string.h or strings.h; this should make gprof compile on
1096           any (Unix) system without configuration (per suggestion of
1097           raeburn@cygnus.com)
1098
1099         * gprof.c (usage): fixed location of --new-file-format option.
1100
1101         * cg_arcs.c (propagate_flags): fixed typo in declaration.
1102
1103         * flat_bl.m: removed formfeed at end of file; the form-feed
1104           is now printed cg_print.c only when necessary.
1105
1106         * major rewrite of gprof---too many changes to mention all of
1107           them.  new features:
1108
1109         + -l now requests profiling at the line level (as opposed
1110           to function level); in this mode, gprof creates a "symbol"
1111           (aka name-list entry) for each line of source code, instead
1112            of one per function)
1113
1114         + support for a new gmon.out file format; the new format
1115           consists of a header with a magic and a version number,
1116           followed by a sequence of profile data; profile data
1117           can any of: (a) PC histogram, (b) call-graph arcs, or
1118           (c) basic-block execution counts; the version number makes
1119           it possible to extend gmon.out in a backwards compatible
1120           fashion
1121
1122         + support for tcov style annotated output: if the gmon.out file
1123           contains basic-block execution counts, the user can request
1124           the generation of annotated source files, much like Sun's
1125           tcov used to do
1126
1127         + long options
1128
1129         + new scheme to suppress symbols that aren't function names
1130           (e.g., avoids mistaking a goto label as a function)
1131
1132         + reorganized source code to make it more managable; as a
1133           side effect, gprof now compiles cleanly with "gcc -Wall"
1134
1135         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1136
1137         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
1138         final cross-check to determine whether a static symbol should be
1139         considered as a function-name.
1140
1141         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1142
1143         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
1144         stdin; this is useful if you wanna keep gmon.out files compressed;
1145         this way you can "gzcat" the compressed file into gprof.
1146
1147         * gprof.c: flag_min_count now initialized with 1 instead of 0.
1148
1149         * basic_blocks.c (bb_annotate_source): added support for creating
1150         .tcov files when option flag_annotate_make_files is TRUE.
1151         (annotate_with_count): all counts less than the minimum count
1152         specified by -m are now annotated with hash-marks.
1153
1154         * gprof.c (main): -A is now followed by a string of option chars.
1155
1156         * basic_blocks.c (annotate_with_count): replaced b->count with
1157         cnt.
1158
1159         * source.c: flag_annotate_source replaced by source_lock_map.
1160
1161         * source.h: source_lock_map added.
1162
1163         * gprof.c (main): new command-line syntax: -S simply specifies
1164         which source-files user is interested in; -A requests annotated
1165         source files and -AA requests that all lines in a source file
1166         are annotated.
1167
1168         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1169
1170         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
1171
1172         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
1173         so s_lowpc etc. get declared.
1174
1175         * arcs.h (doarcs): created.
1176
1177         * arcs.c: reordered static functions such that they get defined
1178         before use.
1179
1180         * gprof.c (main): added options:
1181            -A: request annotation of all source lines (with -S)
1182            -m: minimum execution count (with default basic-block display)
1183            -N: force new file format (only if BSD_COMPATIBLE is defined)
1184            -S: annotate source file
1185            -t: set table length (with -S)
1186
1187         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
1188         source.o time_hist.o
1189
1190         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1191
1192         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
1193         on the fact being able to store a long in a double without loss of
1194         precision; this does not hold on machines with 64 bit longs and 64
1195         bit doubles.

1200         greater than 0.0.  Suggested by Harold Assink
1201         <carlo@sg.tn.tudelft.nl>.

1205         * printgprof.c (printprof): Use free, not cfree.
1206         (printgprof, printindex): Ditto.

1208 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
1209
1210         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
1211         decls extern to keep native HP compiler quiet.
1212

1214
1215         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
1216         __gnu_compiled, for the benefit of systems which add a leading
1217         underscore.

1263
1264         * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
1265         makes (osf1) in which the value of MACHINE can not be changed.
1266         * config/*.mt: Changed appropriately.

1271         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
1272         errors from bfd_get_symtab_upper_bound and

1372 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
1373
1374         * gprof.1: updated SYNOPSIS to match actual behavior.
1375
1376 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
1377
1378         * gen-c-prog.awk:  New awk script, lightly changed from
1379         previously deleted make-c-prog.awk.  Converts a text file
1380         to a c function that prints that text.
1381         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
1382         Inputs to gen-c-prog.awk, containing text describing
1383         gprof output.
1384         * blurbs.c:  Removed.  Use *_bl.c instead.
1385         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1386         from *_bl.m files.  Also, improve *clean rules.
1387         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
1388
1389
1390 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
1391
1392         * gprof.h, gprof.c, printfgprof.c:  Add support for two
1393         output styles:  The default is similar to the old FSF gprof,
1394         while -T sets the variable bsd_style_output, which causes
1395         output matching Berkeley's gprof.  The biggest differences
1396         are that with the FSF style output, the flat profile comes
1397         before the call graph; numbers come before explanations;
1398         and there is less gratuitous white space.
1399         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
1400         variable causes discarding of initial underscores when
1401         printing symbol names.  It is set unless there is a "main"
1402         symbol (without an underscore).
1403         * printfgprof.c:  New function printnameonly(), called
1404         by printname().  It handles stripping of initial '_',
1405         as well as C++ name-demangling.
1406         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
1407         It is just as convenient to edit blurbs.c directly.
1408         * Makefile.in:  Removed rule for making blurbs.c.
1409         * blurbs.c:  This is now a true source file (as opposed
1410         to being generated from gprof.callg and gprof.flat).
1411         Change style to use one long string literal, instead of
