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

367 Thu Feb 9 16:56:07 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
369 * All *.c: More cleanup towards GNU format.
371 * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
372 replaced sizeof (bfd_vma) by size (char*) because Ken tells me
373 that bfd_vma is only guaranteed to be at least as big as a pointer.
375 (GMON_Record_tag): added explicit enumeration values to ensure
376 compatibility across compilers.
378 * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
381 Tue Feb 7 17:24:12 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
383 * All *.c and *.h files: Ran "indent -gnu". Cleaned up a couple
384 of constructs GNU indent couldn't handle. Block comments not yet
385 rewritten in GNU format.
387 * gprof.c (VERSION): Changed to 2.6, to get in sync for next
390 Sun Feb 5 16:19:46 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
392 * symtab.c (symtab_finalize): ensure globals symbols really
393 are favored over static ones---even if their name looks less
394 preferable; this is important for HP-UX; for example, there
395 is a static label Ltext_something that aliases the global
398 * hist.c (hist_print): auto-scaling is now in effect for FSF-style
399 output only; also, auto-scaling is now performed based on
400 per-call, rather than total execution time, which is what it was
403 * gprof.h (File_Format): new type.
405 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
406 sync with Cygnus version numbers though...
408 (long_options): renamed --gmon-info to --file-info, --width added,
409 renamed --old-file-format to --file-format
410 (main): dito; also added support to read prof files, but as
411 mon_out_read() is not implemented, it's #ifdef'd out for now
413 (usage): update to reflect new options.
415 * gmon_io.c: replaced "old_file_format" by more general
418 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
420 * core.c (core_sym_class): added back check for __gnu_compiled and
421 ___gnu_compiled for the benefit of systems without
422 bfd_find_nearest_line() support
424 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
425 with section-relative addresses
427 (core_create_function_syms): get_src_info() calls are currently
428 enabled for OSF/1 only. It appears to work allright for SunOS
429 4.1.x as well, but on SPARCs it gets painfully slow with the
430 current implementation of aout_32_find_nearest_line();
431 unfortunately, this means that static functions will not have their
432 filename printed in the call-graph function index; line-level
433 profiling should still work, but requires some patience
435 * cg_print.c (cg_print_index): sanitized printing of index when
436 using FSF-style output; in particular, output width is now controlled
437 via option --width and the function tries hard to keep columns
438 aligned even in the presence of (occasional) long names
440 * NOTES: a first shot at updating the documentation.
442 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
444 * core.c (core_create_function_syms): fixed computation of min_vma
447 * *.c: removed rcsid.
449 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
451 * Lots of changes from David Mosberger-Tang:
453 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
455 * gprof.c (main): put parentheses around & within &&.
457 * basic_blocks.c (bb_read_rec): print warning message (once) when
458 ignoring basic-block execution counts.
460 * source.c (source_file_lookup_name): corrected second argument to
463 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
464 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
466 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
467 supported both for old and new (versioned) gmon.out files. Old
468 files are identified as version 0.
470 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
471 long (instead of 4) because that is what OSF/1 v3.0 uses.
473 * core.c: minor fixes and debugging info changes.
475 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
477 * core.c (core_init): if .text cannot be found, try $CODE$ (the
478 name of the text-section under HP-UX).
480 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
481 points one past the last sampling bin, so hist_scale should be
482 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
485 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
488 * configure.in: added alpha-*-*) for per-target config.
490 * alpha.c, alpha.h: created.
492 * gprof.c (default_excluded_list): <locore>, <hicore> added.
494 * core.c (core_create_function_syms, core_create_line_syms):
495 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
496 all addresses outside the text-space. Thus, sym_lookup(&symtab,
497 addr) continues to guarantee not to return 0 on any address. It
498 also avoids incorrectly crediting the first/last symbol in the
501 * core.c (core_create_line_syms): always create function symbols
502 first, then merge in line symbols; this is so that if parts of the
503 program were compiled without -g, function-level symbols are
506 * utils.c (print_name_only): support for print_path added.
508 * symtab.c (cmp_addr): also use is_func flag in comparison.
509 (symtab_finalize): return immediately when table empty; now
510 more careful about getting rid of the right duplicate symbol.
512 * sparc.c (find_call): many fixes---this function was rather
513 botched in binutils-2.4 already; it should work again.
515 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
516 not good to rely on get_src_info() to return distinct string
519 * search_list.c (search_list_append): added cast for xmalloc().
521 * hist.c: added explicit initialization to some of the global
522 variables; fixed SItab (scales were off by a factor of 10).
524 * hist.h: include of bfd.h added.
526 * gprof.c, gprof.h (print_path): added.
528 * gprof.h (MAX): fixed.
530 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
532 * gmon_io.c: added some casts to (long) so we can always print as %lx
534 * core.c (core_get_text_space): fixed to make it work.
536 * cg_print.c (cg_print_index): added support for print_path option.
538 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
540 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
541 as some compilers complain (e.g., DEC's OSF/1 compiler)
543 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
544 symtab.c: calls to memset() had 2nd and 3rd args reversed.
546 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
548 * gprof.c: added "_mcount" to default_excluded_list.
549 (main): if output_style==0 and there is either a histogram or a
550 call-graph, always generate flat and call-graph, no matter what
551 line_granularity is set to.
553 * source.c (source_file_lookup_name): if searching for sf->name
554 fails, try again with filename obtained after stripping off any
555 partial path from sf->name.
557 * gprof.h (SRCDEBUG): added.
559 * search_list.c (search_list_append): directories were added in wrong
562 * reimplemented selection mechanism from ground up; it is now possible
563 to accurately control what gets included/excluded in each of the
564 output styles; a "symbol-specification" (spec) is the basic means
565 to select a set of symbols; a spec has the syntax:
567 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
570 any of the terminal symbols can be empty, in which case they
571 match anything (wildcards). NAME is interpreted as a FILENAME
572 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
573 with a digit, and as FUNCNAME otherwise.
575 For example, to get a call-graph display that ignores arcs
576 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
577 show only arcs into bar() (no matter what the caller),
578 you'd say "--graph=/bar"; and to get a call-graph without
579 any arc info, you'd say "--graph=/"; similarly, to
580 get a flat profile without mcount, you'd say "--no-flat=mcount"
581 and to get a flat profile that shows includes all functions
582 you'd say "--flat=""" (i.e., an empty spec)
584 * hist.c (hist_print): top_time wasn't initialized to 0.0.
586 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
588 * gmon_out.h: all headers now declared in terms of characters
589 to avoid getting into trouble with different compilers introducing
590 different amount of padding; the code already accessed the fields
591 through bfd functions, so that didn't have to change.
593 * hist.c (hist_read_rec, hist_write_rec): added support for
594 collection pc histograms measuring quantities other than time;
595 the histogram header now includes a field that specifies the
596 dimension of the quantity measured by the histogram bins
597 (normally, this is "seconds", but other meaningful dimensions
598 include such things as "I-cache misses", "instruction issue stalls"
599 etc.); there is also a field to specify a one-character
600 abbreviation for the dimension; in the case of time, this would
601 be 's'; in most other cases it probably would be '1' (not a physical
604 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
606 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
607 has become old_file_version; gmon_io.c now always supports old-style
608 gmon.out files; it first tries to read gmon.out as a new version
609 file, if that fails, it tries to read it in the old format;
610 although not very likely, it is possible for gprof to mistake an
611 old-style file as a new one (the first 4 bytes would have to
612 be "gmon"---including the trailing '\0'); in that case, it is
613 necessary to specify --old-file-version
615 * gprof.h: removed dependency on SYSV; the code now always uses
616 strrchr(), memset(), and memcpy() and does not include either
617 of string.h or strings.h; this should make gprof compile on
618 any (Unix) system without configuration (per suggestion of
621 * gprof.c (usage): fixed location of --new-file-format option.
623 * cg_arcs.c (propagate_flags): fixed typo in declaration.
625 * flat_bl.m: removed formfeed at end of file; the form-feed
626 is now printed cg_print.c only when necessary.
628 * major rewrite of gprof---too many changes to mention all of
631 + -l now requests profiling at the line level (as opposed
632 to function level); in this mode, gprof creates a "symbol"
633 (aka name-list entry) for each line of source code, instead
636 + support for a new gmon.out file format; the new format
637 consists of a header with a magic and a version number,
638 followed by a sequence of profile data; profile data
639 can any of: (a) PC histogram, (b) call-graph arcs, or
640 (c) basic-block execution counts; the version number makes
641 it possible to extend gmon.out in a backwards compatible
644 + support for tcov style annotated output: if the gmon.out file
645 contains basic-block execution counts, the user can request
646 the generation of annotated source files, much like Sun's
651 + new scheme to suppress symbols that aren't function names
652 (e.g., avoids mistaking a goto label as a function)
654 + reorganized source code to make it more managable; as a
655 side effect, gprof now compiles cleanly with "gcc -Wall"
657 Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
659 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
660 final cross-check to determine whether a static symbol should be
661 considered as a function-name.
663 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
665 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
666 stdin; this is useful if you wanna keep gmon.out files compressed;
667 this way you can "gzcat" the compressed file into gprof.
669 * gprof.c: flag_min_count now initialized with 1 instead of 0.
671 * basic_blocks.c (bb_annotate_source): added support for creating
672 .tcov files when option flag_annotate_make_files is TRUE.
673 (annotate_with_count): all counts less than the minimum count
674 specified by -m are now annotated with hash-marks.
676 * gprof.c (main): -A is now followed by a string of option chars.
678 * basic_blocks.c (annotate_with_count): replaced b->count with
681 * source.c: flag_annotate_source replaced by source_lock_map.
683 * source.h: source_lock_map added.
685 * gprof.c (main): new command-line syntax: -S simply specifies
686 which source-files user is interested in; -A requests annotated
687 source files and -AA requests that all lines in a source file
690 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
692 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
694 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
695 so s_lowpc etc. get declared.
697 * arcs.h (doarcs): created.
699 * arcs.c: reordered static functions such that they get defined
702 * gprof.c (main): added options:
703 -A: request annotation of all source lines (with -S)
704 -m: minimum execution count (with default basic-block display)
705 -N: force new file format (only if BSD_COMPATIBLE is defined)
706 -S: annotate source file
707 -t: set table length (with -S)
709 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
712 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
714 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
715 on the fact being able to store a long in a double without loss of
716 precision; this does not hold on machines with 64 bit longs and 64
719 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
721 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
722 greater than 0.0. Suggested by Harold Assink
723 <carlo@sg.tn.tudelft.nl>.
725 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
727 * printgprof.c (printprof): Use free, not cfree.
728 (printgprof, printindex): Ditto.
730 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
732 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
733 decls extern to keep native HP compiler quiet.
735 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
737 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
738 __gnu_compiled, for the benefit of systems which add a leading
741 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
743 * configure.in: Change i386-*-* to i[345]86-*-*.
745 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)
747 * ns532.c, ns532.h: New Files. ns532 support.
749 * config/mt-ns532: New File. ns532 support.
751 * gprof.c: user register int i instead of defaulting the int.
752 Allows compilation with -Dregister= for debugging.
754 * configure.in: Add ns532 support.
756 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
758 * Makefile.in (gprof): Depend on $(LIBS).
760 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
762 From binutils-2.4 release:
764 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
766 * configure.bat: [new] build makefile from makefile.in (dos)
767 * hertz.c: allow static HERTZ (msdos needs it)
768 * gprof.c: allow target to select "r" or "rb" for fopen
769 * gprof.c: ignore __gnu_compiled symbols
770 * i386.h: dfine FOPEN_RB to "rb" for dos.
772 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
774 * Makefile.in (.m.c:): Added .SUFFIXES : .m
775 so flat_bl.c would make from flat_bl.m file.
777 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
779 * Makefile.in (install-info): Check for gprof.info in build dir,
780 fall back to srcdir. Depend on it.
782 * gprof.h (TRUE, FALSE): Always use undef before defining them.
784 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
786 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
787 makes (osf1) in which the value of MACHINE can not be changed.
788 * config/*.mt: Changed appropriately.
790 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
792 * gprof.c (getsymtab): Change nosyms to long. Rename
793 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
794 errors from bfd_get_symtab_upper_bound and
795 bfd_canonicalize_symtab.
797 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
799 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
802 Sun Mar 20 15:40:21 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
804 * Makefile.in: Avoid bug in hpux sed.
806 Wed Dec 15 20:16:40 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
808 * gprof.texi (Invoking): add text about -v flag

812 Wed Dec 8 16:55:06 1993 david d `zoo' zuhn (zoo@andros.cygnus.com)
814 * gprof.c (VERSION): defined a version macro, print the value
815 when the -v option is used
817 Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
819 * Makefile.in: Install correctly.
821 Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
823 * gprof.c (main): Get whoami from argv, instead of hardcoding.
824 Use it in usage message. Split usage message to fit in 80 cols.
826 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
828 * Makefile.in: Undo 15 June change.
830 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
832 * gmon.h, gprof.h: structs of chars used to hold external
834 * gprof.c (getpfile, openpfile, readsamples): Swap data in using
837 Tue Jun 15 23:09:17 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
839 * Makefile.in (.c.o): Look in ../include, not ../bfd, for bfd.h.
841 Mon Jun 14 16:22:59 1993 david d `zoo' zuhn (zoo at rtl.cygnus.com)
843 * Makefile.in: remove parentdir support
845 Mon Jun 7 12:56:17 1993 Per Bothner (bothner@rtl.cygnus.com)
847 * Makefile.in (INCLUDES): Add -I../bfd for sysdep.h and bfd.h.
848 * configure.in: No longer need to configure to get sysdep.h.
850 Tue May 18 21:44:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
852 * Makefile.in (install): should not depend on install-info
854 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
856 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
858 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
860 * M Makefile.in: Add -g to CFLAGS.
861 Ads LDFLAGS and use in place of CFLAGS where appropriate.
862 * configure.in: Make a sysdep.hlink in the same way other
863 bfd-based directories do.
864 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
866 * gprof.h: #include sysdep.h instead of a bunch of stuff.
867 * gprof.c (main): Fix typo gproff->gprof.
869 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
871 * gprof.texi: add INFO-DIR-ENTRY
873 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
875 * Makefile.in: add installcheck target
877 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)
879 * gprof.c (funcsymbol): Invert test for aflag.
881 Thu Feb 25 16:01:50 1993 Per Bothner (bothner@rtl.cygnus.com)
883 * printgprof (xmalloc, xrealloc): Cast results of malloc
886 Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
888 * Makefile.in: created info, install-info, dvi
890 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
892 * Makefile.in: fix install rule for $(PROG)
894 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
896 * gprof.1: updated SYNOPSIS to match actual behavior.
898 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
900 * gen-c-prog.awk: New awk script, lightly changed from
901 previously deleted make-c-prog.awk. Converts a text file
902 to a c function that prints that text.
903 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
904 Inputs to gen-c-prog.awk, containing text describing
906 * blurbs.c: Removed. Use *_bl.c instead.
907 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
908 from *_bl.m files. Also, improve *clean rules.
909 * printgprof.c (printgprof): Usw new function names from *_bl.c.
912 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
914 * gprof.h, gprof.c, printfgprof.c: Add support for two
915 output styles: The default is similar to the old FSF gprof,
916 while -T sets the variable bsd_style_output, which causes
917 output matching Berkeley's gprof. The biggest differences
918 are that with the FSF style output, the flat profile comes
919 before the call graph; numbers come before explanations;
920 and there is less gratuitous white space.
921 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
922 variable causes discarding of initial underscores when
923 printing symbol names. It is set unless there is a "main"
924 symbol (without an underscore).
925 * printfgprof.c: New function printnameonly(), called
926 by printname(). It handles stripping of initial '_',
927 as well as C++ name-demangling.
928 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
929 It is just as convenient to edit blurbs.c directly.
930 * Makefile.in: Removed rule for making blurbs.c.
931 * blurbs.c: This is now a true source file (as opposed
932 to being generated from gprof.callg and gprof.flat).
933 Change style to use one long string literal, instead of
934 one literal per output line. Add FSF-style blurb for call graph.
936 Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
938 * Makefile.in: always create installation directories.
940 Wed Aug 12 15:14:14 1992 Mark Eichin (eichin@cygnus.com)
942 * Makefile.in: change ${MACHINE} to $(MACHINE).
944 Sun Jul 19 17:34:01 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
946 * Makefile.in: removed installation of the now useless
947 call.{flag,callg} files.
949 * gprof.1: now uses the standard man macros instead of the new BSD
952 Sun Jul 12 19:06:00 1992 John Gilmore (gnu at cygnus.com)
954 * configure.in: Remove host section, expand target section.
955 * config/mt-{tahoe,vax}: Add, to match existing support files.
956 * config/tmake-*: Remove leftover crud.
958 * blurbs.c: New file, created from gprof.flat and gprof.callg by
959 * make-c-prog.awk: which processes text files into C programs.
960 * printgprof.c (flatprofheader, gprofheader): Call new functions
962 (printblurb): Remove.
963 * Makefile.in: Infrastructure to build blurbs.
964 * pathnames.h: has been removed. Gprof now has no filename
968 Sat Jul 11 18:07:21 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
970 * Makefile.in: define man1dir and install the man page
972 Fri Jul 10 21:14:08 1992 david d `zoo' zuhn (zoo@cygnus.com)
974 * Makefile.in: added dummy info and install-info targets
976 Thu Jun 4 11:34:02 1992 Mark Eichin (eichin at cygnus.com)
978 * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
979 help in debugging the problem (with -DDEBUG)
980 * gprof.c: symbol values are now real values, don't add the vma
981 anymore. (done for solaris; should verify this on other platforms)
982 * ChangeLog: created.
