 713 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 714
 715         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 716         that we're using autoconf.
 717
 718 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 719
 720         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
 721         to proper type of "unsigned int *".
 722
 723 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 724
 725         * configure.in: Use changequote around use of [].
 726
 727 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 728
 729         * Makefile.in (distclean, realclean): Remove config.cache and
 730           config.log.
 731
 732 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 733
 734         * Makefile.in (Makefile): Added config.status to dependency list.
 735           (config.status): New target.
 736           (SHELL): New definition.
 737
 738 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 739
 740         * Makefile.in (install): Depend on "all".
 741
 742 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 743
 744         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 745         to match configure script.
 746
 747 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 748
 749         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 750           comment emitted by this script to gen-c-prog.awk.
 751
 752         * Makefile.in, configure.in: Converted to use autoconf.
 753         * configure: New file, generated with autoconf 2.3.
 754         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 755           mt-tahoe, mt-vax}: Removed.
 756
 757 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 758
 759         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 760
 761         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 762
 763         * All *.c: More cleanup towards GNU format.
 764
 765         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 766         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 767         that bfd_vma is only guaranteed to be at least as big as a pointer.
 768
 769         (GMON_Record_tag): added explicit enumeration values to ensure
 770         compatibility across compilers.
 771
 772         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 773         sizeof(char*).
 774
 775 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 776
 777         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 778         of constructs GNU indent couldn't handle.  Block comments not yet
 779         rewritten in GNU format.
 780
 781         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 782         binutils release.
 783
 784 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 785
 786         * symtab.c (symtab_finalize): ensure globals symbols really
 787         are favored over static ones---even if their name looks less
 788         preferable; this is important for HP-UX; for example, there
 789         is a static label Ltext_something that aliases the global
 790         symbol _start
 791
 792         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 793         output only; also, auto-scaling is now performed based on
 794         per-call, rather than total execution time, which is what it was
 795         meant to be.
 796
 797         * gprof.h (File_Format): new type.
 798
 799         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 800         sync with Cygnus version numbers though...
 801
 802         (long_options): renamed --gmon-info to --file-info, --width added,
 803         renamed --old-file-format to --file-format
 804         (main): dito; also added support to read prof files, but as
 805         mon_out_read() is not implemented, it's #ifdef'd out for now
 806
 807         (usage): update to reflect new options.
 808
 809         * gmon_io.c: replaced "old_file_format" by more general
 810         "file_format" option
 811
 812         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 813
 814         * core.c (core_sym_class): added back check for __gnu_compiled and
 815         ___gnu_compiled for the benefit of systems without
 816         bfd_find_nearest_line() support
 817
 818         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 819         with section-relative addresses
 820
 821         (core_create_function_syms): get_src_info() calls are currently
 822         enabled for OSF/1 only.  It appears to work allright for SunOS
 823         4.1.x as well, but on SPARCs it gets painfully slow with the
 824         current implementation of aout_32_find_nearest_line();
 825         unfortunately, this means that static functions will not have their
 826         filename printed in the call-graph function index; line-level
 827         profiling should still work, but requires some patience
 828
 829         * cg_print.c (cg_print_index): sanitised printing of index when
 830         using FSF-style output; in particular, output width is now controlled
 831         via option --width and the function tries hard to keep columns
 832         aligned even in the presence of (occasional) long names
 833
 834         * NOTES: a first shot at updating the documentation.
 835
 836 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 837
 838         * core.c (core_create_function_syms): fixed computation of min_vma
 839         and max_vma.
 840
 841         * *.c: removed rcsid.
 842
 843 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 844
 845         * Lots of changes from David Mosberger-Tang:
 846
 847         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 848
 849         * gprof.c (main): put parentheses around & within &&.
 850
 851         * basic_blocks.c (bb_read_rec): print warning message (once) when
 852         ignoring basic-block execution counts.
 853
 854         * source.c (source_file_lookup_name): corrected second argument to
 855         strcmp().
 856
 857         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 858         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 859
 860         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 861         supported both for old and new (versioned) gmon.out files.  Old
 862         files are identified as version 0.
 863
 864         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 865         long (instead of 4) because that is what OSF/1 v3.0 uses.
 866
 867         * core.c: minor fixes and debugging info changes.
 868
 869         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 870
 871         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 872         name of the text-section under HP-UX).
 873
 874         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 875         points one past the last sampling bin, so hist_scale should be
 876         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 877         hist_num_bins - 1".
 878
 879         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 880         hist_num_bins.
 881
 882         * configure.in: added alpha-*-*) for per-target config.
 883
 884         * alpha.c, alpha.h: created.
 885
 886         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 887
 888         * core.c (core_create_function_syms, core_create_line_syms):
 889         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 890         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 891         addr) continues to guarantee not to return 0 on any address.  It
 892         also avoids incorrectly crediting the first/last symbol in the
 893         text-space.
 894
 895         * core.c (core_create_line_syms): always create function symbols
 896         first, then merge in line symbols; this is so that if parts of the
 897         program were compiled without -g, function-level symbols are
 898         available still.
 899
 900         * utils.c (print_name_only): support for print_path added.
 901
 902         * symtab.c (cmp_addr): also use is_func flag in comparison.
 903         (symtab_finalize): return immediately when table empty; now
 904         more careful about getting rid of the right duplicate symbol.
 905
 906         * sparc.c (find_call): many fixes---this function was rather
 907         botched in binutils-2.4 already; it should work again.
 908
 909         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 910         not good to rely on get_src_info() to return distinct string
 911         pointers).
 912
 913         * search_list.c (search_list_append): added cast for xmalloc().
 914
 915         * hist.c: added explicit initialization to some of the global
 916         variables; fixed SItab (scales were off by a factor of 10).
 917
 918         * hist.h: include of bfd.h added.
 919
 920         * gprof.c, gprof.h (print_path): added.
 921
 922         * gprof.h (MAX): fixed.
 923
 924         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 925
 926         * gmon_io.c: added some casts to (long) so we can always print as %lx
 927
 928         * core.c (core_get_text_space): fixed to make it work.
 929
 930         * cg_print.c (cg_print_index): added support for print_path option.
 931
 932         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 933
 934         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 935         as some compilers complain (e.g., DEC's OSF/1 compiler)
 936
 937         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 938         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 939
 940         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 941
 942         * gprof.c: added "_mcount" to default_excluded_list.
 943         (main): if output_style==0 and there is either a histogram or a
 944         call-graph, always generate flat and call-graph, no matter what
 945         line_granularity is set to.
 946
 947         * source.c (source_file_lookup_name): if searching for sf->name
 948         fails, try again with filename obtained after stripping off any
 949         partial path from sf->name.
 950
 951         * gprof.h (SRCDEBUG): added.
 952
 953         * search_list.c (search_list_append): directories were added in wrong
 954         order.
 955
 956         * reimplemented selection mechanism from ground up; it is now possible
 957         to accurately control what gets included/excluded in each of the
 958         output styles;  a "symbol-specification" (spec) is the basic means
 959         to select a set of symbols; a spec has the syntax:
 960
 961           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 962           arc == spec/spec.
 963
 964         any of the terminal symbols can be empty, in which case they
 965         match anything (wildcards).  NAME is interpreted as a FILENAME
 966         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 967         with a digit, and as FUNCNAME otherwise.
 968
 969         For example, to get a call-graph display that ignores arcs
 970         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 971         show only arcs into bar() (no matter what the caller),
 972         you'd say "--graph=/bar"; and to get a call-graph without
 973         any arc info, you'd say "--graph=/";  similarly, to
 974         get a flat profile without mcount, you'd say "--no-flat=mcount"
 975         and to get a flat profile that shows includes all functions
 976         you'd say "--flat=""" (i.e., an empty spec)
 977
 978         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 979
 980         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 981
 982         * gmon_out.h: all headers now declared in terms of characters
 983           to avoid getting into trouble with different compilers introducing
 984           different amount of padding; the code already accessed the fields
 985           through bfd functions, so that didn't have to change.
 986
 987         * hist.c (hist_read_rec, hist_write_rec): added support for
 988           collection pc histograms measuring quantities other than time;
 989           the histogram header now includes a field that specifies the
 990           dimension of the quantity measured by the histogram bins
 991           (normally, this is "seconds", but other meaningful dimensions
 992            include such things as "I-cache misses", "instruction issue stalls"
 993            etc.); there is also a field to specify a one-character
 994           abbreviation for the dimension; in the case of time, this would
 995           be 's'; in most other cases it probably would be '1' (not a physical
 996           dimension).
 997
 998         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 999
1000         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
1001           has become old_file_version; gmon_io.c now always supports old-style
1002           gmon.out files; it first tries to read gmon.out as a new version
1003           file, if that fails, it tries to read it in the old format;
1004           although not very likely, it is possible for gprof to mistake an
1005           old-style file as a new one (the first 4 bytes would have to
1006           be "gmon"---including the trailing '\0'); in that case, it is
1007           necessary to specify --old-file-version
1008
1009         * gprof.h: removed dependency on SYSV; the code now always uses
1010           strrchr(), memset(), and memcpy() and does not include either
1011           of string.h or strings.h; this should make gprof compile on
1012           any (Unix) system without configuration (per suggestion of
1013           raeburn@cygnus.com)
1014
1015         * gprof.c (usage): fixed location of --new-file-format option.
1016
1017         * cg_arcs.c (propagate_flags): fixed typo in declaration.
1018
1019         * flat_bl.m: removed formfeed at end of file; the form-feed
1020           is now printed cg_print.c only when necessary.
1021
1022         * major rewrite of gprof---too many changes to mention all of
1023           them.  new features:
1024
1025         + -l now requests profiling at the line level (as opposed
1026           to function level); in this mode, gprof creates a "symbol"
1027           (aka name-list entry) for each line of source code, instead
1028            of one per function)
1029
1030         + support for a new gmon.out file format; the new format
1031           consists of a header with a magic and a version number,
1032           followed by a sequence of profile data; profile data
1033           can any of: (a) PC histogram, (b) call-graph arcs, or
1034           (c) basic-block execution counts; the version number makes
1035           it possible to extend gmon.out in a backwards compatible
1036           fashion
1037
1038         + support for tcov style annotated output: if the gmon.out file
1039           contains basic-block execution counts, the user can request
1040           the generation of annotated source files, much like Sun's
1041           tcov used to do
1042
1043         + long options
1044
1045         + new scheme to suppress symbols that aren't function names
1046           (e.g., avoids mistaking a goto label as a function)
1047
1048         + reorganized source code to make it more managable; as a
1049           side effect, gprof now compiles cleanly with "gcc -Wall"
1050
1051         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1052
1053         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
1054         final cross-check to determine whether a static symbol should be
1055         considered as a function-name.
1056
1057         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1058
1059         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
1060         stdin; this is useful if you wanna keep gmon.out files compressed;
1061         this way you can "gzcat" the compressed file into gprof.
1062
1063         * gprof.c: flag_min_count now initialized with 1 instead of 0.
1064
1065         * basic_blocks.c (bb_annotate_source): added support for creating
1066         .tcov files when option flag_annotate_make_files is TRUE.
1067         (annotate_with_count): all counts less than the minimum count
1068         specified by -m are now annotated with hash-marks.
1069
1070         * gprof.c (main): -A is now followed by a string of option chars.
1071
1072         * basic_blocks.c (annotate_with_count): replaced b->count with
1073         cnt.

1080         which source-files user is interested in; -A requests annotated
1081         source files and -AA requests that all lines in a source file
1082         are annotated.

1084         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
1085
1086         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
1087
1088         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
1089         so s_lowpc etc. get declared.

1091         * arcs.h (doarcs): created.
1092
1093         * arcs.c: reordered static functions such that they get defined

1107
1108         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
1109         on the fact being able to store a long in a double without loss of
1110         precision; this does not hold on machines with 64 bit longs and 64
1111         bit doubles.

1287
1288 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
1289
1290         * gprof.1: updated SYNOPSIS to match actual behavior.
1291
1292 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
1293
1294         * gen-c-prog.awk:  New awk script, lightly changed from
1295         previously deleted make-c-prog.awk.  Converts a text file
1296         to a c function that prints that text.
1297         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
1298         Inputs to gen-c-prog.awk, containing text describing
1299         gprof output.
1300         * blurbs.c:  Removed.  Use *_bl.c instead.
1301         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1302         from *_bl.m files.  Also, improve *clean rules.
1303         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
1304
1305
1306 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
1307
1308         * gprof.h, gprof.c, printfgprof.c:  Add support for two
1309         output styles:  The default is similar to the old FSF gprof,
1310         while -T sets the variable bsd_style_output, which causes
1311         output matching Berkeley's gprof.  The biggest differences
1312         are that with the FSF style output, the flat profile comes
1313         before the call graph; numbers come before explanations;
1314         and there is less gratuitous white space.
1315         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
1316         variable causes discarding of initial underscores when
1317         printing symbol names.  It is set unless there is a "main"
1318         symbol (without an underscore).
1319         * printfgprof.c:  New function printnameonly(), called
1320         by printname().  It handles stripping of initial '_',
1321         as well as C++ name-demangling.
1322         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
1323         It is just as convenient to edit blurbs.c directly.
1324         * Makefile.in:  Removed rule for making blurbs.c.
1325         * blurbs.c:  This is now a true source file (as opposed
1326         to being generated from gprof.callg and gprof.flat).
1327         Change style to use one long string literal, instead of
1328         one literal per output line.  Add FSF-style blurb for call graph.
1329
1330 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
1331
1332         * Makefile.in: always create installation directories.

1340         * Makefile.in:  removed installation of the now useless
1341         call.{flag,callg} files.
1342
1343         * gprof.1: now uses the standard man macros instead of the new BSD
1344         mandoc macros.
1345
1346 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
1347
1348         * configure.in:  Remove host section, expand target section.
1349         * config/mt-{tahoe,vax}:  Add, to match existing support files.
1350         * config/tmake-*:  Remove leftover crud.
1351
1352         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
1353         * make-c-prog.awk:  which processes text files into C programs.
1354         * printgprof.c (flatprofheader, gprofheader):  Call new functions
1355         to print blurbs.
1356         (printblurb):  Remove.
1357         * Makefile.in:  Infrastructure to build blurbs.
1358         * pathnames.h:  has been removed.  Gprof now has no filename
1359         dependencies in it.
1360         * gprof.c:  Lint.

1369
1370 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
1371
1372         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
1373         help in debugging the problem (with -DDEBUG)
1374         * gprof.c: symbol values are now real values, don't add the vma
1375         anymore. (done for solaris; should verify this on other platforms)
1376         * ChangeLog: created.
