388 Mon Mar 13 21:44:24 1995 Ken Raeburn <raeburn@cujo.cygnus.com>

392 Thu Feb 9 16:56:07 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
394 * All *.c: More cleanup towards GNU format.
396 * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
397 replaced sizeof (bfd_vma) by size (char*) because Ken tells me
398 that bfd_vma is only guaranteed to be at least as big as a pointer.
400 (GMON_Record_tag): added explicit enumeration values to ensure
401 compatibility across compilers.
403 * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
406 Tue Feb 7 17:24:12 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
408 * All *.c and *.h files: Ran "indent -gnu". Cleaned up a couple
409 of constructs GNU indent couldn't handle. Block comments not yet
410 rewritten in GNU format.
412 * gprof.c (VERSION): Changed to 2.6, to get in sync for next
415 Sun Feb 5 16:19:46 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
417 * symtab.c (symtab_finalize): ensure globals symbols really
418 are favored over static ones---even if their name looks less
419 preferable; this is important for HP-UX; for example, there
420 is a static label Ltext_something that aliases the global
423 * hist.c (hist_print): auto-scaling is now in effect for FSF-style
424 output only; also, auto-scaling is now performed based on
425 per-call, rather than total execution time, which is what it was
428 * gprof.h (File_Format): new type.
430 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
431 sync with Cygnus version numbers though...
433 (long_options): renamed --gmon-info to --file-info, --width added,
434 renamed --old-file-format to --file-format
435 (main): dito; also added support to read prof files, but as
436 mon_out_read() is not implemented, it's #ifdef'd out for now
438 (usage): update to reflect new options.
440 * gmon_io.c: replaced "old_file_format" by more general
443 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
445 * core.c (core_sym_class): added back check for __gnu_compiled and
446 ___gnu_compiled for the benefit of systems without
447 bfd_find_nearest_line() support
449 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
450 with section-relative addresses
452 (core_create_function_syms): get_src_info() calls are currently
453 enabled for OSF/1 only. It appears to work allright for SunOS
454 4.1.x as well, but on SPARCs it gets painfully slow with the
455 current implementation of aout_32_find_nearest_line();
456 unfortunately, this means that static functions will not have their
457 filename printed in the call-graph function index; line-level
458 profiling should still work, but requires some patience
460 * cg_print.c (cg_print_index): sanitised printing of index when
461 using FSF-style output; in particular, output width is now controlled
462 via option --width and the function tries hard to keep columns
463 aligned even in the presence of (occasional) long names
465 * NOTES: a first shot at updating the documentation.
467 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
469 * core.c (core_create_function_syms): fixed computation of min_vma
472 * *.c: removed rcsid.
474 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
476 * Lots of changes from David Mosberger-Tang:
478 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
480 * gprof.c (main): put parentheses around & within &&.
482 * basic_blocks.c (bb_read_rec): print warning message (once) when
483 ignoring basic-block execution counts.
485 * source.c (source_file_lookup_name): corrected second argument to
488 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
489 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
491 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
492 supported both for old and new (versioned) gmon.out files. Old
493 files are identified as version 0.
495 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
496 long (instead of 4) because that is what OSF/1 v3.0 uses.
498 * core.c: minor fixes and debugging info changes.
500 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
502 * core.c (core_init): if .text cannot be found, try $CODE$ (the
503 name of the text-section under HP-UX).
505 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
506 points one past the last sampling bin, so hist_scale should be
507 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
510 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
513 * configure.in: added alpha-*-*) for per-target config.
515 * alpha.c, alpha.h: created.
517 * gprof.c (default_excluded_list): <locore>, <hicore> added.
519 * core.c (core_create_function_syms, core_create_line_syms):
520 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
521 all addresses outside the text-space. Thus, sym_lookup(&symtab,
522 addr) continues to guarantee not to return 0 on any address. It
523 also avoids incorrectly crediting the first/last symbol in the
526 * core.c (core_create_line_syms): always create function symbols
527 first, then merge in line symbols; this is so that if parts of the
528 program were compiled without -g, function-level symbols are
531 * utils.c (print_name_only): support for print_path added.
533 * symtab.c (cmp_addr): also use is_func flag in comparison.
534 (symtab_finalize): return immediately when table empty; now
535 more careful about getting rid of the right duplicate symbol.
537 * sparc.c (find_call): many fixes---this function was rather
538 botched in binutils-2.4 already; it should work again.
540 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
541 not good to rely on get_src_info() to return distinct string
544 * search_list.c (search_list_append): added cast for xmalloc().
546 * hist.c: added explicit initialization to some of the global
547 variables; fixed SItab (scales were off by a factor of 10).
549 * hist.h: include of bfd.h added.
551 * gprof.c, gprof.h (print_path): added.
553 * gprof.h (MAX): fixed.
555 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
557 * gmon_io.c: added some casts to (long) so we can always print as %lx
559 * core.c (core_get_text_space): fixed to make it work.
561 * cg_print.c (cg_print_index): added support for print_path option.
563 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
565 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
566 as some compilers complain (e.g., DEC's OSF/1 compiler)
568 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
569 symtab.c: calls to memset() had 2nd and 3rd args reversed.
571 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
573 * gprof.c: added "_mcount" to default_excluded_list.
574 (main): if output_style==0 and there is either a histogram or a
575 call-graph, always generate flat and call-graph, no matter what
576 line_granularity is set to.
578 * source.c (source_file_lookup_name): if searching for sf->name
579 fails, try again with filename obtained after stripping off any
580 partial path from sf->name.
582 * gprof.h (SRCDEBUG): added.
584 * search_list.c (search_list_append): directories were added in wrong
587 * reimplemented selection mechanism from ground up; it is now possible
588 to accurately control what gets included/excluded in each of the
589 output styles; a "symbol-specification" (spec) is the basic means
590 to select a set of symbols; a spec has the syntax:
592 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
595 any of the terminal symbols can be empty, in which case they
596 match anything (wildcards). NAME is interpreted as a FILENAME
597 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
598 with a digit, and as FUNCNAME otherwise.
600 For example, to get a call-graph display that ignores arcs
601 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
602 show only arcs into bar() (no matter what the caller),
603 you'd say "--graph=/bar"; and to get a call-graph without
604 any arc info, you'd say "--graph=/"; similarly, to
605 get a flat profile without mcount, you'd say "--no-flat=mcount"
606 and to get a flat profile that shows includes all functions
607 you'd say "--flat=""" (i.e., an empty spec)
609 * hist.c (hist_print): top_time wasn't initialized to 0.0.
611 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
613 * gmon_out.h: all headers now declared in terms of characters
614 to avoid getting into trouble with different compilers introducing
615 different amount of padding; the code already accessed the fields
616 through bfd functions, so that didn't have to change.
618 * hist.c (hist_read_rec, hist_write_rec): added support for
619 collection pc histograms measuring quantities other than time;
620 the histogram header now includes a field that specifies the
621 dimension of the quantity measured by the histogram bins
622 (normally, this is "seconds", but other meaningful dimensions
623 include such things as "I-cache misses", "instruction issue stalls"
624 etc.); there is also a field to specify a one-character
625 abbreviation for the dimension; in the case of time, this would
626 be 's'; in most other cases it probably would be '1' (not a physical
629 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
631 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
632 has become old_file_version; gmon_io.c now always supports old-style
633 gmon.out files; it first tries to read gmon.out as a new version
634 file, if that fails, it tries to read it in the old format;
635 although not very likely, it is possible for gprof to mistake an
636 old-style file as a new one (the first 4 bytes would have to
637 be "gmon"---including the trailing '\0'); in that case, it is
638 necessary to specify --old-file-version
640 * gprof.h: removed dependency on SYSV; the code now always uses
641 strrchr(), memset(), and memcpy() and does not include either
642 of string.h or strings.h; this should make gprof compile on
643 any (Unix) system without configuration (per suggestion of
646 * gprof.c (usage): fixed location of --new-file-format option.
648 * cg_arcs.c (propagate_flags): fixed typo in declaration.
650 * flat_bl.m: removed formfeed at end of file; the form-feed
651 is now printed cg_print.c only when necessary.
653 * major rewrite of gprof---too many changes to mention all of
656 + -l now requests profiling at the line level (as opposed
657 to function level); in this mode, gprof creates a "symbol"
658 (aka name-list entry) for each line of source code, instead
661 + support for a new gmon.out file format; the new format
662 consists of a header with a magic and a version number,
663 followed by a sequence of profile data; profile data
664 can any of: (a) PC histogram, (b) call-graph arcs, or
665 (c) basic-block execution counts; the version number makes
666 it possible to extend gmon.out in a backwards compatible
669 + support for tcov style annotated output: if the gmon.out file
670 contains basic-block execution counts, the user can request
671 the generation of annotated source files, much like Sun's
676 + new scheme to suppress symbols that aren't function names
677 (e.g., avoids mistaking a goto label as a function)
679 + reorganized source code to make it more managable; as a
680 side effect, gprof now compiles cleanly with "gcc -Wall"
682 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
684 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
685 final cross-check to determine whether a static symbol should be
686 considered as a function-name.
688 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
690 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
691 stdin; this is useful if you wanna keep gmon.out files compressed;
692 this way you can "gzcat" the compressed file into gprof.
694 * gprof.c: flag_min_count now initialized with 1 instead of 0.
696 * basic_blocks.c (bb_annotate_source): added support for creating
697 .tcov files when option flag_annotate_make_files is TRUE.
698 (annotate_with_count): all counts less than the minimum count
699 specified by -m are now annotated with hash-marks.
701 * gprof.c (main): -A is now followed by a string of option chars.
703 * basic_blocks.c (annotate_with_count): replaced b->count with
706 * source.c: flag_annotate_source replaced by source_lock_map.
708 * source.h: source_lock_map added.
710 * gprof.c (main): new command-line syntax: -S simply specifies
711 which source-files user is interested in; -A requests annotated
712 source files and -AA requests that all lines in a source file
715 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
717 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
719 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
720 so s_lowpc etc. get declared.
722 * arcs.h (doarcs): created.
724 * arcs.c: reordered static functions such that they get defined
727 * gprof.c (main): added options:
728 -A: request annotation of all source lines (with -S)
729 -m: minimum execution count (with default basic-block display)
730 -N: force new file format (only if BSD_COMPATIBLE is defined)
731 -S: annotate source file
732 -t: set table length (with -S)
734 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
737 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
739 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
740 on the fact being able to store a long in a double without loss of
741 precision; this does not hold on machines with 64 bit longs and 64
744 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
746 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
747 greater than 0.0. Suggested by Harold Assink
748 <carlo@sg.tn.tudelft.nl>.
750 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
752 * printgprof.c (printprof): Use free, not cfree.
753 (printgprof, printindex): Ditto.
755 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
757 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
758 decls extern to keep native HP compiler quiet.
760 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
762 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
763 __gnu_compiled, for the benefit of systems which add a leading
766 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
768 * configure.in: Change i386-*-* to i[345]86-*-*.
770 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
772 * ns532.c, ns532.h: New Files. ns532 support.
774 * config/mt-ns532: New File. ns532 support.
776 * gprof.c: user register int i instead of defaulting the int.
777 Allows compilation with -Dregister= for debugging.
779 * configure.in: Add ns532 support.
781 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
783 * Makefile.in (gprof): Depend on $(LIBS).
785 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
787 From binutils-2.4 release:
789 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
791 * configure.bat: [new] build makefile from makefile.in (dos)
792 * hertz.c: allow static HERTZ (msdos needs it)
793 * gprof.c: allow target to select "r" or "rb" for fopen
794 * gprof.c: ignore __gnu_compiled symbols
795 * i386.h: dfine FOPEN_RB to "rb" for dos.
797 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
799 * Makefile.in (.m.c:): Added .SUFFIXES : .m
800 so flat_bl.c would make from flat_bl.m file.
802 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
804 * Makefile.in (install-info): Check for gprof.info in build dir,
805 fall back to srcdir. Depend on it.
807 * gprof.h (TRUE, FALSE): Always use undef before defining them.
809 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
811 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
812 makes (osf1) in which the value of MACHINE can not be changed.
813 * config/*.mt: Changed appropriately.
815 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
817 * gprof.c (getsymtab): Change nosyms to long. Rename
818 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
819 errors from bfd_get_symtab_upper_bound and
820 bfd_canonicalize_symtab.
822 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
824 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
827 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
829 * Makefile.in: Avoid bug in hpux sed.
831 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
833 * gprof.texi (Invoking): add text about -v flag
835 * gprof.1: add text about -v flag
837 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
839 * gprof.c (VERSION): defined a version macro, print the value
840 when the -v option is used
842 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
844 * Makefile.in: Install correctly.
846 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
848 * gprof.c (main): Get whoami from argv, instead of hardcoding.
849 Use it in usage message. Split usage message to fit in 80 cols.
851 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
853 * Makefile.in: Undo 15 June change.
855 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
857 * gmon.h, gprof.h: structs of chars used to hold external
859 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
862 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
864 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
866 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
868 * Makefile.in: remove parentdir support
870 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
872 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
873 * configure.in: No longer need to configure to get sysdep.h.
875 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
877 * Makefile.in (install): should not depend on install-info
879 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
881 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
883 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
885 * M Makefile.in: Add -g to CFLAGS.
886 Ads LDFLAGS and use in place of CFLAGS where appropriate.
887 * configure.in: Make a sysdep.hlink in the same way other
888 bfd-based directories do.
889 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
891 * gprof.h: #include sysdep.h instead of a bunch of stuff.
892 * gprof.c (main): Fix typo gproff->gprof.
894 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
896 * gprof.texi: add INFO-DIR-ENTRY
898 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
900 * Makefile.in: add installcheck target
902 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
904 * gprof.c (funcsymbol): Invert test for aflag.
906 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
908 * printgprof (xmalloc, xrealloc): Cast results of malloc
911 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
913 * Makefile.in: created info, install-info, dvi
915 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
917 * Makefile.in: fix install rule for $(PROG)
919 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
921 * gprof.1: updated SYNOPSIS to match actual behavior.
923 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
925 * gen-c-prog.awk: New awk script, lightly changed from
926 previously deleted make-c-prog.awk. Converts a text file
927 to a c function that prints that text.
928 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
929 Inputs to gen-c-prog.awk, containing text describing
931 * blurbs.c: Removed. Use *_bl.c instead.
932 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
933 from *_bl.m files. Also, improve *clean rules.
934 * printgprof.c (printgprof): Usw new function names from *_bl.c.
937 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
939 * gprof.h, gprof.c, printfgprof.c: Add support for two
940 output styles: The default is similar to the old FSF gprof,
941 while -T sets the variable bsd_style_output, which causes
942 output matching Berkeley's gprof. The biggest differences
943 are that with the FSF style output, the flat profile comes
944 before the call graph; numbers come before explanations;
945 and there is less gratuitous white space.
946 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
947 variable causes discarding of initial underscores when
948 printing symbol names. It is set unless there is a "main"
949 symbol (without an underscore).
950 * printfgprof.c: New function printnameonly(), called
951 by printname(). It handles stripping of initial '_',
952 as well as C++ name-demangling.
953 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
954 It is just as convenient to edit blurbs.c directly.
955 * Makefile.in: Removed rule for making blurbs.c.
956 * blurbs.c: This is now a true source file (as opposed
957 to being generated from gprof.callg and gprof.flat).
958 Change style to use one long string literal, instead of
959 one literal per output line. Add FSF-style blurb for call graph.
961 Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
963 * Makefile.in: always create installation directories.
965 Wed Aug 12 15:14:14 1992 Mark Eichin (eichin@cygnus.com)
967 * Makefile.in: change ${MACHINE} to $(MACHINE).
969 Sun Jul 19 17:34:01 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
971 * Makefile.in: removed installation of the now useless
972 call.{flag,callg} files.
974 * gprof.1: now uses the standard man macros instead of the new BSD
977 Sun Jul 12 19:06:00 1992 John Gilmore (gnu at cygnus.com)
979 * configure.in: Remove host section, expand target section.
980 * config/mt-{tahoe,vax}: Add, to match existing support files.
981 * config/tmake-*: Remove leftover crud.
983 * blurbs.c: New file, created from gprof.flat and gprof.callg by
984 * make-c-prog.awk: which processes text files into C programs.
985 * printgprof.c (flatprofheader, gprofheader): Call new functions
987 (printblurb): Remove.
988 * Makefile.in: Infrastructure to build blurbs.
989 * pathnames.h: has been removed. Gprof now has no filename
993 Sat Jul 11 18:07:21 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
995 * Makefile.in: define man1dir and install the man page
997 Fri Jul 10 21:14:08 1992 david d `zoo' zuhn (zoo@cygnus.com)
999 * Makefile.in: added dummy info and install-info targets
1001 Thu Jun 4 11:34:02 1992 Mark Eichin (eichin at cygnus.com)
1003 * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
1004 help in debugging the problem (with -DDEBUG)
1005 * gprof.c: symbol values are now real values, don't add the vma
1006 anymore. (done for solaris; should verify this on other platforms)
1007 * ChangeLog: created.
