539 * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
542 Tue Feb 7 17:24:12 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
544 * All *.c and *.h files: Ran "indent -gnu". Cleaned up a couple
545 of constructs GNU indent couldn't handle. Block comments not yet
546 rewritten in GNU format.
548 * gprof.c (VERSION): Changed to 2.6, to get in sync for next
551 Sun Feb 5 16:19:46 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
553 * symtab.c (symtab_finalize): ensure globals symbols really
554 are favored over static ones---even if their name looks less
555 preferable; this is important for HP-UX; for example, there
556 is a static label Ltext_something that aliases the global
559 * hist.c (hist_print): auto-scaling is now in effect for FSF-style
560 output only; also, auto-scaling is now performed based on
561 per-call, rather than total execution time, which is what it was
564 * gprof.h (File_Format): new type.
566 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
567 sync with Cygnus version numbers though...
569 (long_options): renamed --gmon-info to --file-info, --width added,
570 renamed --old-file-format to --file-format
571 (main): dito; also added support to read prof files, but as
572 mon_out_read() is not implemented, it's #ifdef'd out for now
574 (usage): update to reflect new options.
576 * gmon_io.c: replaced "old_file_format" by more general
579 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
581 * core.c (core_sym_class): added back check for __gnu_compiled and
582 ___gnu_compiled for the benefit of systems without
583 bfd_find_nearest_line() support
585 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
586 with section-relative addresses
588 (core_create_function_syms): get_src_info() calls are currently
589 enabled for OSF/1 only. It appears to work allright for SunOS
590 4.1.x as well, but on SPARCs it gets painfully slow with the
591 current implementation of aout_32_find_nearest_line();
592 unfortunately, this means that static functions will not have their
593 filename printed in the call-graph function index; line-level
594 profiling should still work, but requires some patience
596 * cg_print.c (cg_print_index): sanitised printing of index when
597 using FSF-style output; in particular, output width is now controlled
598 via option --width and the function tries hard to keep columns
599 aligned even in the presence of (occasional) long names
601 * NOTES: a first shot at updating the documentation.
603 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
605 * core.c (core_create_function_syms): fixed computation of min_vma
608 * *.c: removed rcsid.
610 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
612 * Lots of changes from David Mosberger-Tang:
614 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
616 * gprof.c (main): put parentheses around & within &&.
618 * basic_blocks.c (bb_read_rec): print warning message (once) when
619 ignoring basic-block execution counts.
621 * source.c (source_file_lookup_name): corrected second argument to
624 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
625 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
627 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
628 supported both for old and new (versioned) gmon.out files. Old
629 files are identified as version 0.
631 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
632 long (instead of 4) because that is what OSF/1 v3.0 uses.
634 * core.c: minor fixes and debugging info changes.
636 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
638 * core.c (core_init): if .text cannot be found, try $CODE$ (the
639 name of the text-section under HP-UX).
641 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
642 points one past the last sampling bin, so hist_scale should be
643 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
646 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
649 * configure.in: added alpha-*-*) for per-target config.
651 * alpha.c, alpha.h: created.
653 * gprof.c (default_excluded_list): <locore>, <hicore> added.
655 * core.c (core_create_function_syms, core_create_line_syms):
656 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
657 all addresses outside the text-space. Thus, sym_lookup(&symtab,
658 addr) continues to guarantee not to return 0 on any address. It
659 also avoids incorrectly crediting the first/last symbol in the
662 * core.c (core_create_line_syms): always create function symbols
663 first, then merge in line symbols; this is so that if parts of the
664 program were compiled without -g, function-level symbols are
667 * utils.c (print_name_only): support for print_path added.
669 * symtab.c (cmp_addr): also use is_func flag in comparison.
670 (symtab_finalize): return immediately when table empty; now
671 more careful about getting rid of the right duplicate symbol.
673 * sparc.c (find_call): many fixes---this function was rather
674 botched in binutils-2.4 already; it should work again.
676 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
677 not good to rely on get_src_info() to return distinct string
680 * search_list.c (search_list_append): added cast for xmalloc().
682 * hist.c: added explicit initialization to some of the global
683 variables; fixed SItab (scales were off by a factor of 10).
685 * hist.h: include of bfd.h added.
687 * gprof.c, gprof.h (print_path): added.
689 * gprof.h (MAX): fixed.
691 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
693 * gmon_io.c: added some casts to (long) so we can always print as %lx
695 * core.c (core_get_text_space): fixed to make it work.
697 * cg_print.c (cg_print_index): added support for print_path option.
699 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
701 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
702 as some compilers complain (e.g., DEC's OSF/1 compiler)
704 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
705 symtab.c: calls to memset() had 2nd and 3rd args reversed.
707 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
709 * gprof.c: added "_mcount" to default_excluded_list.
710 (main): if output_style==0 and there is either a histogram or a
711 call-graph, always generate flat and call-graph, no matter what
712 line_granularity is set to.
714 * source.c (source_file_lookup_name): if searching for sf->name
715 fails, try again with filename obtained after stripping off any
716 partial path from sf->name.
718 * gprof.h (SRCDEBUG): added.
720 * search_list.c (search_list_append): directories were added in wrong
723 * reimplemented selection mechanism from ground up; it is now possible
724 to accurately control what gets included/excluded in each of the
725 output styles; a "symbol-specification" (spec) is the basic means
726 to select a set of symbols; a spec has the syntax:
728 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
731 any of the terminal symbols can be empty, in which case they
732 match anything (wildcards). NAME is interpreted as a FILENAME
733 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
734 with a digit, and as FUNCNAME otherwise.
736 For example, to get a call-graph display that ignores arcs
737 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
738 show only arcs into bar() (no matter what the caller),
739 you'd say "--graph=/bar"; and to get a call-graph without
740 any arc info, you'd say "--graph=/"; similarly, to
741 get a flat profile without mcount, you'd say "--no-flat=mcount"
742 and to get a flat profile that shows includes all functions
743 you'd say "--flat=""" (i.e., an empty spec)
745 * hist.c (hist_print): top_time wasn't initialized to 0.0.
747 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
749 * gmon_out.h: all headers now declared in terms of characters
750 to avoid getting into trouble with different compilers introducing
751 different amount of padding; the code already accessed the fields
752 through bfd functions, so that didn't have to change.
754 * hist.c (hist_read_rec, hist_write_rec): added support for
755 collection pc histograms measuring quantities other than time;
756 the histogram header now includes a field that specifies the
757 dimension of the quantity measured by the histogram bins
758 (normally, this is "seconds", but other meaningful dimensions
759 include such things as "I-cache misses", "instruction issue stalls"
760 etc.); there is also a field to specify a one-character
761 abbreviation for the dimension; in the case of time, this would
762 be 's'; in most other cases it probably would be '1' (not a physical
765 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
767 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
768 has become old_file_version; gmon_io.c now always supports old-style
769 gmon.out files; it first tries to read gmon.out as a new version
770 file, if that fails, it tries to read it in the old format;
771 although not very likely, it is possible for gprof to mistake an
772 old-style file as a new one (the first 4 bytes would have to
773 be "gmon"---including the trailing '\0'); in that case, it is
774 necessary to specify --old-file-version
776 * gprof.h: removed dependency on SYSV; the code now always uses
777 strrchr(), memset(), and memcpy() and does not include either
778 of string.h or strings.h; this should make gprof compile on
779 any (Unix) system without configuration (per suggestion of
782 * gprof.c (usage): fixed location of --new-file-format option.
784 * cg_arcs.c (propagate_flags): fixed typo in declaration.
786 * flat_bl.m: removed formfeed at end of file; the form-feed
787 is now printed cg_print.c only when necessary.
789 * major rewrite of gprof---too many changes to mention all of
792 + -l now requests profiling at the line level (as opposed
793 to function level); in this mode, gprof creates a "symbol"
794 (aka name-list entry) for each line of source code, instead
797 + support for a new gmon.out file format; the new format
798 consists of a header with a magic and a version number,
799 followed by a sequence of profile data; profile data
800 can any of: (a) PC histogram, (b) call-graph arcs, or
801 (c) basic-block execution counts; the version number makes
802 it possible to extend gmon.out in a backwards compatible
805 + support for tcov style annotated output: if the gmon.out file
806 contains basic-block execution counts, the user can request
807 the generation of annotated source files, much like Sun's
812 + new scheme to suppress symbols that aren't function names
813 (e.g., avoids mistaking a goto label as a function)
815 + reorganized source code to make it more managable; as a
816 side effect, gprof now compiles cleanly with "gcc -Wall"
818 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
820 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
821 final cross-check to determine whether a static symbol should be
822 considered as a function-name.
824 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
826 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
827 stdin; this is useful if you wanna keep gmon.out files compressed;
828 this way you can "gzcat" the compressed file into gprof.
830 * gprof.c: flag_min_count now initialized with 1 instead of 0.
832 * basic_blocks.c (bb_annotate_source): added support for creating
833 .tcov files when option flag_annotate_make_files is TRUE.
834 (annotate_with_count): all counts less than the minimum count
835 specified by -m are now annotated with hash-marks.
837 * gprof.c (main): -A is now followed by a string of option chars.
839 * basic_blocks.c (annotate_with_count): replaced b->count with
842 * source.c: flag_annotate_source replaced by source_lock_map.
844 * source.h: source_lock_map added.
846 * gprof.c (main): new command-line syntax: -S simply specifies
847 which source-files user is interested in; -A requests annotated
848 source files and -AA requests that all lines in a source file
851 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
853 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
855 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
856 so s_lowpc etc. get declared.
858 * arcs.h (doarcs): created.
860 * arcs.c: reordered static functions such that they get defined
863 * gprof.c (main): added options:
864 -A: request annotation of all source lines (with -S)
865 -m: minimum execution count (with default basic-block display)
866 -N: force new file format (only if BSD_COMPATIBLE is defined)
867 -S: annotate source file
868 -t: set table length (with -S)
870 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
873 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
875 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
876 on the fact being able to store a long in a double without loss of
877 precision; this does not hold on machines with 64 bit longs and 64
880 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
882 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
883 greater than 0.0. Suggested by Harold Assink
884 <carlo@sg.tn.tudelft.nl>.
886 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
888 * printgprof.c (printprof): Use free, not cfree.
889 (printgprof, printindex): Ditto.
891 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
893 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
894 decls extern to keep native HP compiler quiet.
896 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
898 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
899 __gnu_compiled, for the benefit of systems which add a leading
902 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
904 * configure.in: Change i386-*-* to i[345]86-*-*.
906 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
908 * ns532.c, ns532.h: New Files. ns532 support.
910 * config/mt-ns532: New File. ns532 support.
912 * gprof.c: user register int i instead of defaulting the int.
913 Allows compilation with -Dregister= for debugging.
915 * configure.in: Add ns532 support.
917 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
919 * Makefile.in (gprof): Depend on $(LIBS).
921 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
923 From binutils-2.4 release:
925 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
927 * configure.bat: [new] build makefile from makefile.in (dos)
928 * hertz.c: allow static HERTZ (msdos needs it)
929 * gprof.c: allow target to select "r" or "rb" for fopen
930 * gprof.c: ignore __gnu_compiled symbols
931 * i386.h: dfine FOPEN_RB to "rb" for dos.
933 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
935 * Makefile.in (.m.c:): Added .SUFFIXES : .m
936 so flat_bl.c would make from flat_bl.m file.
938 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
940 * Makefile.in (install-info): Check for gprof.info in build dir,
941 fall back to srcdir. Depend on it.
943 * gprof.h (TRUE, FALSE): Always use undef before defining them.
945 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
947 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
948 makes (osf1) in which the value of MACHINE can not be changed.
949 * config/*.mt: Changed appropriately.
951 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
953 * gprof.c (getsymtab): Change nosyms to long. Rename
954 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
955 errors from bfd_get_symtab_upper_bound and
956 bfd_canonicalize_symtab.
958 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
960 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
963 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
965 * Makefile.in: Avoid bug in hpux sed.
967 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
969 * gprof.texi (Invoking): add text about -v flag
971 * gprof.1: add text about -v flag
973 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
975 * gprof.c (VERSION): defined a version macro, print the value
976 when the -v option is used
978 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
980 * Makefile.in: Install correctly.
982 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
984 * gprof.c (main): Get whoami from argv, instead of hardcoding.
985 Use it in usage message. Split usage message to fit in 80 cols.
987 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
989 * Makefile.in: Undo 15 June change.
991 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
993 * gmon.h, gprof.h: structs of chars used to hold external
995 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
998 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
1000 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
1002 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
1004 * Makefile.in: remove parentdir support
1006 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
1008 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
1009 * configure.in: No longer need to configure to get sysdep.h.
1011 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1013 * Makefile.in (install): should not depend on install-info
1015 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
1017 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
1019 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
1021 * M Makefile.in: Add -g to CFLAGS.
1022 Ads LDFLAGS and use in place of CFLAGS where appropriate.
1023 * configure.in: Make a sysdep.hlink in the same way other
1024 bfd-based directories do.
1025 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
1027 * gprof.h: #include sysdep.h instead of a bunch of stuff.
1028 * gprof.c (main): Fix typo gproff->gprof.
1030 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1032 * gprof.texi: add INFO-DIR-ENTRY
1034 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1036 * Makefile.in: add installcheck target
1038 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
1040 * gprof.c (funcsymbol): Invert test for aflag.
1042 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
1044 * printgprof (xmalloc, xrealloc): Cast results of malloc
1047 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
1049 * Makefile.in: created info, install-info, dvi
1051 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1053 * Makefile.in: fix install rule for $(PROG)
1055 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
1057 * gprof.1: updated SYNOPSIS to match actual behavior.
1059 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
1061 * gen-c-prog.awk: New awk script, lightly changed from
1062 previously deleted make-c-prog.awk. Converts a text file
1063 to a c function that prints that text.
1064 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
1065 Inputs to gen-c-prog.awk, containing text describing
1067 * blurbs.c: Removed. Use *_bl.c instead.
1068 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
1069 from *_bl.m files. Also, improve *clean rules.
1070 * printgprof.c (printgprof): Usw new function names from *_bl.c.
1073 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
1075 * gprof.h, gprof.c, printfgprof.c: Add support for two
1076 output styles: The default is similar to the old FSF gprof,
1077 while -T sets the variable bsd_style_output, which causes
1078 output matching Berkeley's gprof. The biggest differences
1079 are that with the FSF style output, the flat profile comes
1080 before the call graph; numbers come before explanations;
1081 and there is less gratuitous white space.
1082 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
1083 variable causes discarding of initial underscores when
1084 printing symbol names. It is set unless there is a "main"
1085 symbol (without an underscore).
1086 * printfgprof.c: New function printnameonly(), called
1087 by printname(). It handles stripping of initial '_',
1088 as well as C++ name-demangling.
1089 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
1090 It is just as convenient to edit blurbs.c directly.
1091 * Makefile.in: Removed rule for making blurbs.c.
1092 * blurbs.c: This is now a true source file (as opposed
1093 to being generated from gprof.callg and gprof.flat).
1094 Change style to use one long string literal, instead of
1095 one literal per output line. Add FSF-style blurb for call graph.
1097 Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
1099 * Makefile.in: always create installation directories.
1101 Wed Aug 12 15:14:14 1992 Mark Eichin (eichin@cygnus.com)
1103 * Makefile.in: change ${MACHINE} to $(MACHINE).
1105 Sun Jul 19 17:34:01 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1107 * Makefile.in: removed installation of the now useless
1108 call.{flag,callg} files.
1110 * gprof.1: now uses the standard man macros instead of the new BSD
1113 Sun Jul 12 19:06:00 1992 John Gilmore (gnu at cygnus.com)
1115 * configure.in: Remove host section, expand target section.
1116 * config/mt-{tahoe,vax}: Add, to match existing support files.
1117 * config/tmake-*: Remove leftover crud.
1119 * blurbs.c: New file, created from gprof.flat and gprof.callg by
1120 * make-c-prog.awk: which processes text files into C programs.
1121 * printgprof.c (flatprofheader, gprofheader): Call new functions
1123 (printblurb): Remove.
1124 * Makefile.in: Infrastructure to build blurbs.
1125 * pathnames.h: has been removed. Gprof now has no filename
1129 Sat Jul 11 18:07:21 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1131 * Makefile.in: define man1dir and install the man page
1133 Fri Jul 10 21:14:08 1992 david d `zoo' zuhn (zoo@cygnus.com)
1135 * Makefile.in: added dummy info and install-info targets
1137 Thu Jun 4 11:34:02 1992 Mark Eichin (eichin at cygnus.com)
1139 * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
1140 help in debugging the problem (with -DDEBUG)
1141 * gprof.c: symbol values are now real values, don't add the vma
1142 anymore. (done for solaris; should verify this on other platforms)
1143 * ChangeLog: created.
