 712         * configure.in: Use changequote around use of [].
 713
 714 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 715
 716         * Makefile.in (distclean, realclean): Remove config.cache and
 717           config.log.
 718
 719 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 720
 721         * Makefile.in (Makefile): Added config.status to dependency list.
 722           (config.status): New target.
 723           (SHELL): New definition.
 724
 725 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 726
 727         * Makefile.in (install): Depend on "all".
 728
 729 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 730
 731         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 732         to match configure script.
 733
 734 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 735
 736         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 737           comment emitted by this script to gen-c-prog.awk.
 738
 739         * Makefile.in, configure.in: Converted to use autoconf.
 740         * configure: New file, generated with autoconf 2.3.
 741         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 742           mt-tahoe, mt-vax}: Removed.
 743
 744 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 745
 746         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 747
 748         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 749
 750         * All *.c: More cleanup towards GNU format.
 751
 752         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 753         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 754         that bfd_vma is only guaranteed to be at least as big as a pointer.
 755
 756         (GMON_Record_tag): added explicit enumeration values to ensure
 757         compatibility across compilers.
 758
 759         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 760         sizeof(char*).
 761
 762 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 763
 764         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 765         of constructs GNU indent couldn't handle.  Block comments not yet
 766         rewritten in GNU format.
 767
 768         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 769         binutils release.
 770
 771 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 772
 773         * symtab.c (symtab_finalize): ensure globals symbols really
 774         are favored over static ones---even if their name looks less
 775         preferable; this is important for HP-UX; for example, there
 776         is a static label Ltext_something that aliases the global
 777         symbol _start
 778
 779         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 780         output only; also, auto-scaling is now performed based on
 781         per-call, rather than total execution time, which is what it was
 782         meant to be.
 783
 784         * gprof.h (File_Format): new type.
 785
 786         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 787         sync with Cygnus version numbers though...
 788
 789         (long_options): renamed --gmon-info to --file-info, --width added,
 790         renamed --old-file-format to --file-format
 791         (main): dito; also added support to read prof files, but as
 792         mon_out_read() is not implemented, it's #ifdef'd out for now
 793
 794         (usage): update to reflect new options.
 795
 796         * gmon_io.c: replaced "old_file_format" by more general
 797         "file_format" option
 798
 799         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 800
 801         * core.c (core_sym_class): added back check for __gnu_compiled and
 802         ___gnu_compiled for the benefit of systems without
 803         bfd_find_nearest_line() support
 804
 805         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 806         with section-relative addresses
 807
 808         (core_create_function_syms): get_src_info() calls are currently
 809         enabled for OSF/1 only.  It appears to work allright for SunOS
 810         4.1.x as well, but on SPARCs it gets painfully slow with the
 811         current implementation of aout_32_find_nearest_line();
 812         unfortunately, this means that static functions will not have their
 813         filename printed in the call-graph function index; line-level
 814         profiling should still work, but requires some patience
 815
 816         * cg_print.c (cg_print_index): sanitised printing of index when
 817         using FSF-style output; in particular, output width is now controlled
 818         via option --width and the function tries hard to keep columns
 819         aligned even in the presence of (occasional) long names
 820
 821         * NOTES: a first shot at updating the documentation.
 822
 823 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 824
 825         * core.c (core_create_function_syms): fixed computation of min_vma
 826         and max_vma.
 827
 828         * *.c: removed rcsid.
 829
 830 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 831
 832         * Lots of changes from David Mosberger-Tang:
 833
 834         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 835
 836         * gprof.c (main): put parentheses around & within &&.
 837
 838         * basic_blocks.c (bb_read_rec): print warning message (once) when
 839         ignoring basic-block execution counts.
 840
 841         * source.c (source_file_lookup_name): corrected second argument to
 842         strcmp().
 843
 844         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 845         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 846
 847         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 848         supported both for old and new (versioned) gmon.out files.  Old
 849         files are identified as version 0.
 850
 851         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 852         long (instead of 4) because that is what OSF/1 v3.0 uses.
 853
 854         * core.c: minor fixes and debugging info changes.
 855
 856         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 857
 858         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 859         name of the text-section under HP-UX).
 860
 861         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 862         points one past the last sampling bin, so hist_scale should be
 863         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 864         hist_num_bins - 1".
 865
 866         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 867         hist_num_bins.
 868
 869         * configure.in: added alpha-*-*) for per-target config.
 870
 871         * alpha.c, alpha.h: created.
 872
 873         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 874
 875         * core.c (core_create_function_syms, core_create_line_syms):
 876         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 877         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 878         addr) continues to guarantee not to return 0 on any address.  It
 879         also avoids incorrectly crediting the first/last symbol in the
 880         text-space.
 881
 882         * core.c (core_create_line_syms): always create function symbols
 883         first, then merge in line symbols; this is so that if parts of the
 884         program were compiled without -g, function-level symbols are
 885         available still.
 886
 887         * utils.c (print_name_only): support for print_path added.
 888
 889         * symtab.c (cmp_addr): also use is_func flag in comparison.
 890         (symtab_finalize): return immediately when table empty; now
 891         more careful about getting rid of the right duplicate symbol.
 892
 893         * sparc.c (find_call): many fixes---this function was rather
 894         botched in binutils-2.4 already; it should work again.
 895
 896         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 897         not good to rely on get_src_info() to return distinct string
 898         pointers).
 899
 900         * search_list.c (search_list_append): added cast for xmalloc().
 901
 902         * hist.c: added explicit initialization to some of the global
 903         variables; fixed SItab (scales were off by a factor of 10).
 904
 905         * hist.h: include of bfd.h added.
 906
 907         * gprof.c, gprof.h (print_path): added.
 908
 909         * gprof.h (MAX): fixed.
 910
 911         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 912
 913         * gmon_io.c: added some casts to (long) so we can always print as %lx
 914
 915         * core.c (core_get_text_space): fixed to make it work.
 916
 917         * cg_print.c (cg_print_index): added support for print_path option.
 918
 919         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 920
 921         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 922         as some compilers complain (e.g., DEC's OSF/1 compiler)
 923
 924         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 925         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 926
 927         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 928
 929         * gprof.c: added "_mcount" to default_excluded_list.
 930         (main): if output_style==0 and there is either a histogram or a
 931         call-graph, always generate flat and call-graph, no matter what
 932         line_granularity is set to.
 933
 934         * source.c (source_file_lookup_name): if searching for sf->name
 935         fails, try again with filename obtained after stripping off any
 936         partial path from sf->name.
 937
 938         * gprof.h (SRCDEBUG): added.
 939
 940         * search_list.c (search_list_append): directories were added in wrong
 941         order.
 942
 943         * reimplemented selection mechanism from ground up; it is now possible
 944         to accurately control what gets included/excluded in each of the
 945         output styles;  a "symbol-specification" (spec) is the basic means
 946         to select a set of symbols; a spec has the syntax:
 947
 948           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 949           arc == spec/spec.
 950
 951         any of the terminal symbols can be empty, in which case they
 952         match anything (wildcards).  NAME is interpreted as a FILENAME
 953         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 954         with a digit, and as FUNCNAME otherwise.
 955
 956         For example, to get a call-graph display that ignores arcs
 957         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 958         show only arcs into bar() (no matter what the caller),
 959         you'd say "--graph=/bar"; and to get a call-graph without
 960         any arc info, you'd say "--graph=/";  similarly, to
 961         get a flat profile without mcount, you'd say "--no-flat=mcount"
 962         and to get a flat profile that shows includes all functions
 963         you'd say "--flat=""" (i.e., an empty spec)
 964
 965         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 966
 967         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 968
 969         * gmon_out.h: all headers now declared in terms of characters
 970           to avoid getting into trouble with different compilers introducing
 971           different amount of padding; the code already accessed the fields
 972           through bfd functions, so that didn't have to change.
 973
 974         * hist.c (hist_read_rec, hist_write_rec): added support for
 975           collection pc histograms measuring quantities other than time;
 976           the histogram header now includes a field that specifies the
 977           dimension of the quantity measured by the histogram bins
 978           (normally, this is "seconds", but other meaningful dimensions
 979            include such things as "I-cache misses", "instruction issue stalls"
 980            etc.); there is also a field to specify a one-character
 981           abbreviation for the dimension; in the case of time, this would
 982           be 's'; in most other cases it probably would be '1' (not a physical
 983           dimension).
 984
 985         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 986
 987         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 988           has become old_file_version; gmon_io.c now always supports old-style
 989           gmon.out files; it first tries to read gmon.out as a new version
 990           file, if that fails, it tries to read it in the old format;
 991           although not very likely, it is possible for gprof to mistake an
 992           old-style file as a new one (the first 4 bytes would have to
 993           be "gmon"---including the trailing '\0'); in that case, it is
 994           necessary to specify --old-file-version
 995
 996         * gprof.h: removed dependency on SYSV; the code now always uses
 997           strrchr(), memset(), and memcpy() and does not include either
 998           of string.h or strings.h; this should make gprof compile on
 999           any (Unix) system without configuration (per suggestion of
1000           raeburn@cygnus.com)
1001
1002         * gprof.c (usage): fixed location of --new-file-format option.
1003
1004         * cg_arcs.c (propagate_flags): fixed typo in declaration.
1005
1006         * flat_bl.m: removed formfeed at end of file; the form-feed
1007           is now printed cg_print.c only when necessary.
1008
1009         * major rewrite of gprof---too many changes to mention all of
1010           them.  new features:
1011
1012         + -l now requests profiling at the line level (as opposed
1013           to function level); in this mode, gprof creates a "symbol"
1014           (aka name-list entry) for each line of source code, instead
1015            of one per function)
1016
1017         + support for a new gmon.out file format; the new format
1018           consists of a header with a magic and a version number,
1019           followed by a sequence of profile data; profile data
1020           can any of: (a) PC histogram, (b) call-graph arcs, or
1021           (c) basic-block execution counts; the version number makes
1022           it possible to extend gmon.out in a backwards compatible
1023           fashion
1024
1025         + support for tcov style annotated output: if the gmon.out file
1026           contains basic-block execution counts, the user can request
1027           the generation of annotated source files, much like Sun's
1028           tcov used to do
1029
1030         + long options
1031
1032         + new scheme to suppress symbols that aren't function names
1033           (e.g., avoids mistaking a goto label as a function)
1034
1035         + reorganized source code to make it more managable; as a
1036           side effect, gprof now compiles cleanly with "gcc -Wall"
1037
1038         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1039
1040         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
1041         final cross-check to determine whether a static symbol should be
1042         considered as a function-name.
1043
1044         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1045
1046         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
1047         stdin; this is useful if you wanna keep gmon.out files compressed;
1048         this way you can "gzcat" the compressed file into gprof.
1049
1050         * gprof.c: flag_min_count now initialized with 1 instead of 0.
1051
1052         * basic_blocks.c (bb_annotate_source): added support for creating
1053         .tcov files when option flag_annotate_make_files is TRUE.
1054         (annotate_with_count): all counts less than the minimum count
1055         specified by -m are now annotated with hash-marks.
1056
1057         * gprof.c (main): -A is now followed by a string of option chars.
1058
1059         * basic_blocks.c (annotate_with_count): replaced b->count with
1060         cnt.
1061
1062         * source.c: flag_annotate_source replaced by source_lock_map.
1063
1064         * source.h: source_lock_map added.
1065
1066         * gprof.c (main): new command-line syntax: -S simply specifies
1067         which source-files user is interested in; -A requests annotated
1068         source files and -AA requests that all lines in a source file
1069         are annotated.

1071         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1072
1073         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
1074
1075         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
1076         so s_lowpc etc. get declared.
1077
1078         * arcs.h (doarcs): created.
1079
1080         * arcs.c: reordered static functions such that they get defined
1081         before use.
1082
1083         * gprof.c (main): added options:
1084            -A: request annotation of all source lines (with -S)

1094
1095         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
1096         on the fact being able to store a long in a double without loss of
1097         precision; this does not hold on machines with 64 bit longs and 64
1098         bit doubles.

1274
1275 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
1276
1277         * gprof.1: updated SYNOPSIS to match actual behavior.
1278
1279 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
1280
1281         * gen-c-prog.awk:  New awk script, lightly changed from
1282         previously deleted make-c-prog.awk.  Converts a text file
1283         to a c function that prints that text.
1284         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
1285         Inputs to gen-c-prog.awk, containing text describing
1286         gprof output.
1287         * blurbs.c:  Removed.  Use *_bl.c instead.
1288         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1289         from *_bl.m files.  Also, improve *clean rules.
1290         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
1291
1292
1293 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
1294
1295         * gprof.h, gprof.c, printfgprof.c:  Add support for two
1296         output styles:  The default is similar to the old FSF gprof,
1297         while -T sets the variable bsd_style_output, which causes
1298         output matching Berkeley's gprof.  The biggest differences
1299         are that with the FSF style output, the flat profile comes
1300         before the call graph; numbers come before explanations;
1301         and there is less gratuitous white space.
1302         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
1303         variable causes discarding of initial underscores when
1304         printing symbol names.  It is set unless there is a "main"
1305         symbol (without an underscore).
1306         * printfgprof.c:  New function printnameonly(), called
1307         by printname().  It handles stripping of initial '_',
1308         as well as C++ name-demangling.
1309         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
1310         It is just as convenient to edit blurbs.c directly.
1311         * Makefile.in:  Removed rule for making blurbs.c.
1312         * blurbs.c:  This is now a true source file (as opposed
1313         to being generated from gprof.callg and gprof.flat).
1314         Change style to use one long string literal, instead of
1315         one literal per output line.  Add FSF-style blurb for call graph.
1316
1317 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
1318
1319         * Makefile.in: always create installation directories.
1320
1321 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
1322

1327         * Makefile.in:  removed installation of the now useless
1328         call.{flag,callg} files.
1329
1330         * gprof.1: now uses the standard man macros instead of the new BSD
1331         mandoc macros.
1332
1333 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
1334
1335         * configure.in:  Remove host section, expand target section.
1336         * config/mt-{tahoe,vax}:  Add, to match existing support files.
1337         * config/tmake-*:  Remove leftover crud.
1338
1339         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
1340         * make-c-prog.awk:  which processes text files into C programs.
1341         * printgprof.c (flatprofheader, gprofheader):  Call new functions
1342         to print blurbs.
1343         (printblurb):  Remove.
1344         * Makefile.in:  Infrastructure to build blurbs.
1345         * pathnames.h:  has been removed.  Gprof now has no filename
1346         dependencies in it.
1347         * gprof.c:  Lint.

1356
1357 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
1358
1359         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
1360         help in debugging the problem (with -DDEBUG)
1361         * gprof.c: symbol values are now real values, don't add the vma
1362         anymore. (done for solaris; should verify this on other platforms)
1363         * ChangeLog: created.
