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

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

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