331 * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
332 to match configure script.
334 Wed Apr 19 11:19:37 1995 J.T. Conklin <jtc@rtl.cygnus.com>
336 * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in

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

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