397 Thu Feb 9 16:56:07 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
399 * All *.c: More cleanup towards GNU format.
401 * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
402 replaced sizeof (bfd_vma) by size (char*) because Ken tells me
403 that bfd_vma is only guaranteed to be at least as big as a pointer.
405 (GMON_Record_tag): added explicit enumeration values to ensure
406 compatibility across compilers.
408 * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
411 Tue Feb 7 17:24:12 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
413 * All *.c and *.h files: Ran "indent -gnu". Cleaned up a couple
414 of constructs GNU indent couldn't handle. Block comments not yet
415 rewritten in GNU format.
417 * gprof.c (VERSION): Changed to 2.6, to get in sync for next
420 Sun Feb 5 16:19:46 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
422 * symtab.c (symtab_finalize): ensure globals symbols really
423 are favored over static ones---even if their name looks less
424 preferable; this is important for HP-UX; for example, there
425 is a static label Ltext_something that aliases the global
428 * hist.c (hist_print): auto-scaling is now in effect for FSF-style
429 output only; also, auto-scaling is now performed based on
430 per-call, rather than total execution time, which is what it was
433 * gprof.h (File_Format): new type.
435 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
436 sync with Cygnus version numbers though...
438 (long_options): renamed --gmon-info to --file-info, --width added,
439 renamed --old-file-format to --file-format
440 (main): dito; also added support to read prof files, but as
441 mon_out_read() is not implemented, it's #ifdef'd out for now
443 (usage): update to reflect new options.
445 * gmon_io.c: replaced "old_file_format" by more general
448 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
450 * core.c (core_sym_class): added back check for __gnu_compiled and
451 ___gnu_compiled for the benefit of systems without
452 bfd_find_nearest_line() support
454 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
455 with section-relative addresses
457 (core_create_function_syms): get_src_info() calls are currently
458 enabled for OSF/1 only. It appears to work allright for SunOS
459 4.1.x as well, but on SPARCs it gets painfully slow with the
460 current implementation of aout_32_find_nearest_line();
461 unfortunately, this means that static functions will not have their
462 filename printed in the call-graph function index; line-level
463 profiling should still work, but requires some patience
465 * cg_print.c (cg_print_index): sanitised printing of index when
466 using FSF-style output; in particular, output width is now controlled
467 via option --width and the function tries hard to keep columns
468 aligned even in the presence of (occasional) long names
470 * NOTES: a first shot at updating the documentation.
472 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
474 * core.c (core_create_function_syms): fixed computation of min_vma
477 * *.c: removed rcsid.
479 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
481 * Lots of changes from David Mosberger-Tang:
483 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
485 * gprof.c (main): put parentheses around & within &&.
487 * basic_blocks.c (bb_read_rec): print warning message (once) when
488 ignoring basic-block execution counts.
490 * source.c (source_file_lookup_name): corrected second argument to
493 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
494 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
496 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
497 supported both for old and new (versioned) gmon.out files. Old
498 files are identified as version 0.
500 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
501 long (instead of 4) because that is what OSF/1 v3.0 uses.
503 * core.c: minor fixes and debugging info changes.
505 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
507 * core.c (core_init): if .text cannot be found, try $CODE$ (the
508 name of the text-section under HP-UX).
510 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
511 points one past the last sampling bin, so hist_scale should be
512 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
515 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
518 * configure.in: added alpha-*-*) for per-target config.
520 * alpha.c, alpha.h: created.
522 * gprof.c (default_excluded_list): <locore>, <hicore> added.
524 * core.c (core_create_function_syms, core_create_line_syms):
525 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
526 all addresses outside the text-space. Thus, sym_lookup(&symtab,
527 addr) continues to guarantee not to return 0 on any address. It
528 also avoids incorrectly crediting the first/last symbol in the
531 * core.c (core_create_line_syms): always create function symbols
532 first, then merge in line symbols; this is so that if parts of the
533 program were compiled without -g, function-level symbols are
536 * utils.c (print_name_only): support for print_path added.
538 * symtab.c (cmp_addr): also use is_func flag in comparison.
539 (symtab_finalize): return immediately when table empty; now
540 more careful about getting rid of the right duplicate symbol.
542 * sparc.c (find_call): many fixes---this function was rather
543 botched in binutils-2.4 already; it should work again.
545 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
546 not good to rely on get_src_info() to return distinct string
549 * search_list.c (search_list_append): added cast for xmalloc().
551 * hist.c: added explicit initialization to some of the global
552 variables; fixed SItab (scales were off by a factor of 10).
554 * hist.h: include of bfd.h added.
556 * gprof.c, gprof.h (print_path): added.
558 * gprof.h (MAX): fixed.
560 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
562 * gmon_io.c: added some casts to (long) so we can always print as %lx
564 * core.c (core_get_text_space): fixed to make it work.
566 * cg_print.c (cg_print_index): added support for print_path option.
568 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
570 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
571 as some compilers complain (e.g., DEC's OSF/1 compiler)
573 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
574 symtab.c: calls to memset() had 2nd and 3rd args reversed.
576 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
578 * gprof.c: added "_mcount" to default_excluded_list.
579 (main): if output_style==0 and there is either a histogram or a
580 call-graph, always generate flat and call-graph, no matter what
581 line_granularity is set to.
583 * source.c (source_file_lookup_name): if searching for sf->name
584 fails, try again with filename obtained after stripping off any
585 partial path from sf->name.
587 * gprof.h (SRCDEBUG): added.
589 * search_list.c (search_list_append): directories were added in wrong
592 * reimplemented selection mechanism from ground up; it is now possible
593 to accurately control what gets included/excluded in each of the
594 output styles; a "symbol-specification" (spec) is the basic means
595 to select a set of symbols; a spec has the syntax:
597 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
600 any of the terminal symbols can be empty, in which case they
601 match anything (wildcards). NAME is interpreted as a FILENAME
602 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
603 with a digit, and as FUNCNAME otherwise.
605 For example, to get a call-graph display that ignores arcs
606 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
607 show only arcs into bar() (no matter what the caller),
608 you'd say "--graph=/bar"; and to get a call-graph without
609 any arc info, you'd say "--graph=/"; similarly, to
610 get a flat profile without mcount, you'd say "--no-flat=mcount"
611 and to get a flat profile that shows includes all functions
612 you'd say "--flat=""" (i.e., an empty spec)
614 * hist.c (hist_print): top_time wasn't initialized to 0.0.
616 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
618 * gmon_out.h: all headers now declared in terms of characters
619 to avoid getting into trouble with different compilers introducing
620 different amount of padding; the code already accessed the fields
621 through bfd functions, so that didn't have to change.
623 * hist.c (hist_read_rec, hist_write_rec): added support for
624 collection pc histograms measuring quantities other than time;
625 the histogram header now includes a field that specifies the
626 dimension of the quantity measured by the histogram bins
627 (normally, this is "seconds", but other meaningful dimensions
628 include such things as "I-cache misses", "instruction issue stalls"
629 etc.); there is also a field to specify a one-character
630 abbreviation for the dimension; in the case of time, this would
631 be 's'; in most other cases it probably would be '1' (not a physical
634 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
636 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
637 has become old_file_version; gmon_io.c now always supports old-style
638 gmon.out files; it first tries to read gmon.out as a new version
639 file, if that fails, it tries to read it in the old format;
640 although not very likely, it is possible for gprof to mistake an
641 old-style file as a new one (the first 4 bytes would have to
642 be "gmon"---including the trailing '\0'); in that case, it is
643 necessary to specify --old-file-version
645 * gprof.h: removed dependency on SYSV; the code now always uses
646 strrchr(), memset(), and memcpy() and does not include either
647 of string.h or strings.h; this should make gprof compile on
648 any (Unix) system without configuration (per suggestion of
651 * gprof.c (usage): fixed location of --new-file-format option.
653 * cg_arcs.c (propagate_flags): fixed typo in declaration.
655 * flat_bl.m: removed formfeed at end of file; the form-feed
656 is now printed cg_print.c only when necessary.
658 * major rewrite of gprof---too many changes to mention all of
661 + -l now requests profiling at the line level (as opposed
662 to function level); in this mode, gprof creates a "symbol"
663 (aka name-list entry) for each line of source code, instead
666 + support for a new gmon.out file format; the new format
667 consists of a header with a magic and a version number,
668 followed by a sequence of profile data; profile data
669 can any of: (a) PC histogram, (b) call-graph arcs, or
670 (c) basic-block execution counts; the version number makes
671 it possible to extend gmon.out in a backwards compatible
674 + support for tcov style annotated output: if the gmon.out file
675 contains basic-block execution counts, the user can request
676 the generation of annotated source files, much like Sun's
681 + new scheme to suppress symbols that aren't function names
682 (e.g., avoids mistaking a goto label as a function)
684 + reorganized source code to make it more managable; as a
685 side effect, gprof now compiles cleanly with "gcc -Wall"
687 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
689 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
690 final cross-check to determine whether a static symbol should be
691 considered as a function-name.
693 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
695 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
696 stdin; this is useful if you wanna keep gmon.out files compressed;
697 this way you can "gzcat" the compressed file into gprof.
699 * gprof.c: flag_min_count now initialized with 1 instead of 0.
701 * basic_blocks.c (bb_annotate_source): added support for creating
702 .tcov files when option flag_annotate_make_files is TRUE.
703 (annotate_with_count): all counts less than the minimum count
704 specified by -m are now annotated with hash-marks.
706 * gprof.c (main): -A is now followed by a string of option chars.
708 * basic_blocks.c (annotate_with_count): replaced b->count with
711 * source.c: flag_annotate_source replaced by source_lock_map.
713 * source.h: source_lock_map added.
715 * gprof.c (main): new command-line syntax: -S simply specifies
716 which source-files user is interested in; -A requests annotated
717 source files and -AA requests that all lines in a source file
720 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
722 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
724 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
725 so s_lowpc etc. get declared.
727 * arcs.h (doarcs): created.
729 * arcs.c: reordered static functions such that they get defined
732 * gprof.c (main): added options:
733 -A: request annotation of all source lines (with -S)
734 -m: minimum execution count (with default basic-block display)
735 -N: force new file format (only if BSD_COMPATIBLE is defined)
736 -S: annotate source file
737 -t: set table length (with -S)
739 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
742 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
744 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
745 on the fact being able to store a long in a double without loss of
746 precision; this does not hold on machines with 64 bit longs and 64
749 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
751 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
752 greater than 0.0. Suggested by Harold Assink
753 <carlo@sg.tn.tudelft.nl>.
755 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
757 * printgprof.c (printprof): Use free, not cfree.
758 (printgprof, printindex): Ditto.
760 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
762 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
763 decls extern to keep native HP compiler quiet.
765 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
767 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
768 __gnu_compiled, for the benefit of systems which add a leading
771 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
773 * configure.in: Change i386-*-* to i[345]86-*-*.
775 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
777 * ns532.c, ns532.h: New Files. ns532 support.
779 * config/mt-ns532: New File. ns532 support.
781 * gprof.c: user register int i instead of defaulting the int.
782 Allows compilation with -Dregister= for debugging.
784 * configure.in: Add ns532 support.
786 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
788 * Makefile.in (gprof): Depend on $(LIBS).
790 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
792 From binutils-2.4 release:
794 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
796 * configure.bat: [new] build makefile from makefile.in (dos)
797 * hertz.c: allow static HERTZ (msdos needs it)
798 * gprof.c: allow target to select "r" or "rb" for fopen
799 * gprof.c: ignore __gnu_compiled symbols
800 * i386.h: dfine FOPEN_RB to "rb" for dos.
802 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
804 * Makefile.in (.m.c:): Added .SUFFIXES : .m
805 so flat_bl.c would make from flat_bl.m file.
807 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
809 * Makefile.in (install-info): Check for gprof.info in build dir,
810 fall back to srcdir. Depend on it.
812 * gprof.h (TRUE, FALSE): Always use undef before defining them.
814 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
816 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
817 makes (osf1) in which the value of MACHINE can not be changed.
818 * config/*.mt: Changed appropriately.
820 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
822 * gprof.c (getsymtab): Change nosyms to long. Rename
823 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
824 errors from bfd_get_symtab_upper_bound and
825 bfd_canonicalize_symtab.
827 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
829 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
832 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
834 * Makefile.in: Avoid bug in hpux sed.
836 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
838 * gprof.texi (Invoking): add text about -v flag
840 * gprof.1: add text about -v flag
842 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
844 * gprof.c (VERSION): defined a version macro, print the value
845 when the -v option is used
847 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
849 * Makefile.in: Install correctly.
851 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
853 * gprof.c (main): Get whoami from argv, instead of hardcoding.
854 Use it in usage message. Split usage message to fit in 80 cols.
856 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
858 * Makefile.in: Undo 15 June change.
860 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
862 * gmon.h, gprof.h: structs of chars used to hold external
864 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
867 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
869 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
871 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
873 * Makefile.in: remove parentdir support
875 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
877 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
878 * configure.in: No longer need to configure to get sysdep.h.
880 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
882 * Makefile.in (install): should not depend on install-info
884 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
886 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
888 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
890 * M Makefile.in: Add -g to CFLAGS.
891 Ads LDFLAGS and use in place of CFLAGS where appropriate.
892 * configure.in: Make a sysdep.hlink in the same way other
893 bfd-based directories do.
894 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
896 * gprof.h: #include sysdep.h instead of a bunch of stuff.
897 * gprof.c (main): Fix typo gproff->gprof.
899 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
901 * gprof.texi: add INFO-DIR-ENTRY
903 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
905 * Makefile.in: add installcheck target
907 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
909 * gprof.c (funcsymbol): Invert test for aflag.
911 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
913 * printgprof (xmalloc, xrealloc): Cast results of malloc
916 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
918 * Makefile.in: created info, install-info, dvi
920 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
922 * Makefile.in: fix install rule for $(PROG)
924 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
926 * gprof.1: updated SYNOPSIS to match actual behavior.
928 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
930 * gen-c-prog.awk: New awk script, lightly changed from
931 previously deleted make-c-prog.awk. Converts a text file
932 to a c function that prints that text.
933 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
934 Inputs to gen-c-prog.awk, containing text describing
936 * blurbs.c: Removed. Use *_bl.c instead.
937 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
938 from *_bl.m files. Also, improve *clean rules.
939 * printgprof.c (printgprof): Usw new function names from *_bl.c.
942 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
944 * gprof.h, gprof.c, printfgprof.c: Add support for two
945 output styles: The default is similar to the old FSF gprof,
946 while -T sets the variable bsd_style_output, which causes
947 output matching Berkeley's gprof. The biggest differences
948 are that with the FSF style output, the flat profile comes
949 before the call graph; numbers come before explanations;
950 and there is less gratuitous white space.
951 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
952 variable causes discarding of initial underscores when
953 printing symbol names. It is set unless there is a "main"
954 symbol (without an underscore).
955 * printfgprof.c: New function printnameonly(), called
956 by printname(). It handles stripping of initial '_',
957 as well as C++ name-demangling.
958 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
959 It is just as convenient to edit blurbs.c directly.
960 * Makefile.in: Removed rule for making blurbs.c.
961 * blurbs.c: This is now a true source file (as opposed
962 to being generated from gprof.callg and gprof.flat).
963 Change style to use one long string literal, instead of
964 one literal per output line. Add FSF-style blurb for call graph.
966 Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
968 * Makefile.in: always create installation directories.
970 Wed Aug 12 15:14:14 1992 Mark Eichin (eichin@cygnus.com)
972 * Makefile.in: change ${MACHINE} to $(MACHINE).
974 Sun Jul 19 17:34:01 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
976 * Makefile.in: removed installation of the now useless
977 call.{flag,callg} files.
979 * gprof.1: now uses the standard man macros instead of the new BSD
982 Sun Jul 12 19:06:00 1992 John Gilmore (gnu at cygnus.com)
984 * configure.in: Remove host section, expand target section.
985 * config/mt-{tahoe,vax}: Add, to match existing support files.
986 * config/tmake-*: Remove leftover crud.
988 * blurbs.c: New file, created from gprof.flat and gprof.callg by
989 * make-c-prog.awk: which processes text files into C programs.
990 * printgprof.c (flatprofheader, gprofheader): Call new functions
992 (printblurb): Remove.
993 * Makefile.in: Infrastructure to build blurbs.
994 * pathnames.h: has been removed. Gprof now has no filename
998 Sat Jul 11 18:07:21 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1000 * Makefile.in: define man1dir and install the man page
1002 Fri Jul 10 21:14:08 1992 david d `zoo' zuhn (zoo@cygnus.com)
1004 * Makefile.in: added dummy info and install-info targets
1006 Thu Jun 4 11:34:02 1992 Mark Eichin (eichin at cygnus.com)
1008 * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
1009 help in debugging the problem (with -DDEBUG)
1010 * gprof.c: symbol values are now real values, don't add the vma
1011 anymore. (done for solaris; should verify this on other platforms)
1012 * ChangeLog: created.
