219 Tue Aug 22 10:00:45 1995 Jeffrey A. Law <law@rtl.cygnus.com>
221 * Makefile.in (install): Remove "brokensed" hack, unnecessary now
222 that we're using autoconf.
224 Wed Jul 19 18:46:13 1995 Fred Fish <fnf@cygnus.com>
226 * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line

248 Thu Apr 20 17:29:07 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
250 * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
251 to match configure script.
253 Wed Apr 19 11:19:37 1995 J.T. Conklin <jtc@rtl.cygnus.com>
255 * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
256 comment emitted by this script to gen-c-prog.awk.
258 * Makefile.in, configure.in: Converted to use autoconf.
259 * configure: New file, generated with autoconf 2.3.
260 * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
261 mt-tahoe, mt-vax}: Removed.
263 Mon Mar 13 21:44:24 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
265 * __bb_exit_func.c: New file, from David Mosberger-Tang.
267 Thu Feb 9 16:56:07 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
269 * All *.c: More cleanup towards GNU format.
271 * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
272 replaced sizeof (bfd_vma) by size (char*) because Ken tells me
273 that bfd_vma is only guaranteed to be at least as big as a pointer.
275 (GMON_Record_tag): added explicit enumeration values to ensure
276 compatibility across compilers.
278 * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
281 Tue Feb 7 17:24:12 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
283 * All *.c and *.h files: Ran "indent -gnu". Cleaned up a couple
284 of constructs GNU indent couldn't handle. Block comments not yet
285 rewritten in GNU format.
287 * gprof.c (VERSION): Changed to 2.6, to get in sync for next
290 Sun Feb 5 16:19:46 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
292 * symtab.c (symtab_finalize): ensure globals symbols really
293 are favored over static ones---even if their name looks less
294 preferable; this is important for HP-UX; for example, there
295 is a static label Ltext_something that aliases the global
298 * hist.c (hist_print): auto-scaling is now in effect for FSF-style
299 output only; also, auto-scaling is now performed based on
300 per-call, rather than total execution time, which is what it was
303 * gprof.h (File_Format): new type.
305 * gprof.c (VERSION): upped to 2.7---seems to be completely out of
306 sync with Cygnus version numbers though...
308 (long_options): renamed --gmon-info to --file-info, --width added,
309 renamed --old-file-format to --file-format
310 (main): dito; also added support to read prof files, but as
311 mon_out_read() is not implemented, it's #ifdef'd out for now
313 (usage): update to reflect new options.
315 * gmon_io.c: replaced "old_file_format" by more general
318 * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
320 * core.c (core_sym_class): added back check for __gnu_compiled and
321 ___gnu_compiled for the benefit of systems without
322 bfd_find_nearest_line() support
324 (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
325 with section-relative addresses
327 (core_create_function_syms): get_src_info() calls are currently
328 enabled for OSF/1 only. It appears to work allright for SunOS
329 4.1.x as well, but on SPARCs it gets painfully slow with the
330 current implementation of aout_32_find_nearest_line();
331 unfortunately, this means that static functions will not have their
332 filename printed in the call-graph function index; line-level
333 profiling should still work, but requires some patience
335 * cg_print.c (cg_print_index): sanitized printing of index when
336 using FSF-style output; in particular, output width is now controlled
337 via option --width and the function tries hard to keep columns
338 aligned even in the presence of (occasional) long names
340 * NOTES: a first shot at updating the documentation.
342 Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
344 * core.c (core_create_function_syms): fixed computation of min_vma
347 * *.c: removed rcsid.
349 Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
351 * Lots of changes from David Mosberger-Tang:
353 Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
355 * gprof.c (main): put parentheses around & within &&.
357 * basic_blocks.c (bb_read_rec): print warning message (once) when
358 ignoring basic-block execution counts.
360 * source.c (source_file_lookup_name): corrected second argument to
363 * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
364 Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
366 * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
367 supported both for old and new (versioned) gmon.out files. Old
368 files are identified as version 0.
370 * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
371 long (instead of 4) because that is what OSF/1 v3.0 uses.
373 * core.c: minor fixes and debugging info changes.
375 Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
377 * core.c (core_init): if .text cannot be found, try $CODE$ (the
378 name of the text-section under HP-UX).
380 * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
381 points one past the last sampling bin, so hist_scale should be
382 computed as "hist_scale /= hist_num_bins", not "hist_scale /=
385 * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
388 * configure.in: added alpha-*-*) for per-target config.
390 * alpha.c, alpha.h: created.
392 * gprof.c (default_excluded_list): <locore>, <hicore> added.
394 * core.c (core_create_function_syms, core_create_line_syms):
395 explicitly keep two sentinels "<locore>" and "<hicore>" that catch
396 all addresses outside the text-space. Thus, sym_lookup(&symtab,
397 addr) continues to guarantee not to return 0 on any address. It
398 also avoids incorrectly crediting the first/last symbol in the
401 * core.c (core_create_line_syms): always create function symbols
402 first, then merge in line symbols; this is so that if parts of the
403 program were compiled without -g, function-level symbols are
406 * utils.c (print_name_only): support for print_path added.
408 * symtab.c (cmp_addr): also use is_func flag in comparison.
409 (symtab_finalize): return immediately when table empty; now
410 more careful about getting rid of the right duplicate symbol.
412 * sparc.c (find_call): many fixes---this function was rather
413 botched in binutils-2.4 already; it should work again.
415 * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
416 not good to rely on get_src_info() to return distinct string
419 * search_list.c (search_list_append): added cast for xmalloc().
421 * hist.c: added explicit initialization to some of the global
422 variables; fixed SItab (scales were off by a factor of 10).
424 * hist.h: include of bfd.h added.
426 * gprof.c, gprof.h (print_path): added.
428 * gprof.h (MAX): fixed.
430 * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
432 * gmon_io.c: added some casts to (long) so we can always print as %lx
434 * core.c (core_get_text_space): fixed to make it work.
436 * cg_print.c (cg_print_index): added support for print_path option.
438 * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
440 * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
441 as some compilers complain (e.g., DEC's OSF/1 compiler)
443 * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
444 symtab.c: calls to memset() had 2nd and 3rd args reversed.
446 Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
448 * gprof.c: added "_mcount" to default_excluded_list.
449 (main): if output_style==0 and there is either a histogram or a
450 call-graph, always generate flat and call-graph, no matter what
451 line_granularity is set to.
453 * source.c (source_file_lookup_name): if searching for sf->name
454 fails, try again with filename obtained after stripping off any
455 partial path from sf->name.
457 * gprof.h (SRCDEBUG): added.
459 * search_list.c (search_list_append): directories were added in wrong
462 * reimplemented selection mechanism from ground up; it is now possible
463 to accurately control what gets included/excluded in each of the
464 output styles; a "symbol-specification" (spec) is the basic means
465 to select a set of symbols; a spec has the syntax:
467 spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
470 any of the terminal symbols can be empty, in which case they
471 match anything (wildcards). NAME is interpreted as a FILENAME
472 if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
473 with a digit, and as FUNCNAME otherwise.
475 For example, to get a call-graph display that ignores arcs
476 from foo() to bar(), you'd say "--no-graph=foo/bar"; to
477 show only arcs into bar() (no matter what the caller),
478 you'd say "--graph=/bar"; and to get a call-graph without
479 any arc info, you'd say "--graph=/"; similarly, to
480 get a flat profile without mcount, you'd say "--no-flat=mcount"
481 and to get a flat profile that shows includes all functions
482 you'd say "--flat=""" (i.e., an empty spec)
484 * hist.c (hist_print): top_time wasn't initialized to 0.0.
486 Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
488 * gmon_out.h: all headers now declared in terms of characters
489 to avoid getting into trouble with different compilers introducing
490 different amount of padding; the code already accessed the fields
491 through bfd functions, so that didn't have to change.
493 * hist.c (hist_read_rec, hist_write_rec): added support for
494 collection pc histograms measuring quantities other than time;
495 the histogram header now includes a field that specifies the
496 dimension of the quantity measured by the histogram bins
497 (normally, this is "seconds", but other meaningful dimensions
498 include such things as "I-cache misses", "instruction issue stalls"
499 etc.); there is also a field to specify a one-character
500 abbreviation for the dimension; in the case of time, this would
501 be 's'; in most other cases it probably would be '1' (not a physical
504 Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
506 * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
507 has become old_file_version; gmon_io.c now always supports old-style
508 gmon.out files; it first tries to read gmon.out as a new version
509 file, if that fails, it tries to read it in the old format;
510 although not very likely, it is possible for gprof to mistake an
511 old-style file as a new one (the first 4 bytes would have to
512 be "gmon"---including the trailing '\0'); in that case, it is
513 necessary to specify --old-file-version
515 * gprof.h: removed dependency on SYSV; the code now always uses
516 strrchr(), memset(), and memcpy() and does not include either
517 of string.h or strings.h; this should make gprof compile on
518 any (Unix) system without configuration (per suggestion of
521 * gprof.c (usage): fixed location of --new-file-format option.
523 * cg_arcs.c (propagate_flags): fixed typo in declaration.
525 * flat_bl.m: removed formfeed at end of file; the form-feed
526 is now printed cg_print.c only when necessary.
528 * major rewrite of gprof---too many changes to mention all of
531 + -l now requests profiling at the line level (as opposed
532 to function level); in this mode, gprof creates a "symbol"
533 (aka name-list entry) for each line of source code, instead
536 + support for a new gmon.out file format; the new format
537 consists of a header with a magic and a version number,
538 followed by a sequence of profile data; profile data
539 can any of: (a) PC histogram, (b) call-graph arcs, or
540 (c) basic-block execution counts; the version number makes
541 it possible to extend gmon.out in a backwards compatible
544 + support for tcov style annotated output: if the gmon.out file
545 contains basic-block execution counts, the user can request
546 the generation of annotated source files, much like Sun's
551 + new scheme to suppress symbols that aren't function names
552 (e.g., avoids mistaking a goto label as a function)
554 + reorganized source code to make it more managable; as a
555 side effect, gprof now compiles cleanly with "gcc -Wall"

559 * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
560 final cross-check to determine whether a static symbol should be
561 considered as a function-name.
563 Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
565 * gmon_io.c (gmon_out_read): recognize "-" as the filename for
566 stdin; this is useful if you wanna keep gmon.out files compressed;
567 this way you can "gzcat" the compressed file into gprof.
569 * gprof.c: flag_min_count now initialized with 1 instead of 0.
571 * basic_blocks.c (bb_annotate_source): added support for creating
572 .tcov files when option flag_annotate_make_files is TRUE.
573 (annotate_with_count): all counts less than the minimum count
574 specified by -m are now annotated with hash-marks.
576 * gprof.c (main): -A is now followed by a string of option chars.
578 * basic_blocks.c (annotate_with_count): replaced b->count with
581 * source.c: flag_annotate_source replaced by source_lock_map.
583 * source.h: source_lock_map added.
585 * gprof.c (main): new command-line syntax: -S simply specifies
586 which source-files user is interested in; -A requests annotated
587 source files and -AA requests that all lines in a source file
590 Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
592 * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
594 * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
595 so s_lowpc etc. get declared.
597 * arcs.h (doarcs): created.
599 * arcs.c: reordered static functions such that they get defined
602 * gprof.c (main): added options:
603 -A: request annotation of all source lines (with -S)
604 -m: minimum execution count (with default basic-block display)
605 -N: force new file format (only if BSD_COMPATIBLE is defined)
606 -S: annotate source file
607 -t: set table length (with -S)
609 * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
612 Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
614 * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
615 on the fact being able to store a long in a double without loss of
616 precision; this does not hold on machines with 64 bit longs and 64
619 Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
621 * printgprof.c (flatprofheader): Always set totime to 1.0 if not
622 greater than 0.0. Suggested by Harold Assink
623 <carlo@sg.tn.tudelft.nl>.
625 Fri Sep 23 15:06:45 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
627 * printgprof.c (printprof): Use free, not cfree.
628 (printgprof, printindex): Ditto.
630 Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
632 * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
633 decls extern to keep native HP compiler quiet.
635 Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
637 * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
638 __gnu_compiled, for the benefit of systems which add a leading
641 Wed Aug 24 12:49:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
643 * configure.in: Change i386-*-* to i[345]86-*-*.
645 Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)

649 * config/mt-ns532: New File. ns532 support.
651 * gprof.c: user register int i instead of defaulting the int.
652 Allows compilation with -Dregister= for debugging.
654 * configure.in: Add ns532 support.
656 Thu Jun 23 11:22:41 1994 Jeff Law (law@snake.cs.utah.edu)
658 * Makefile.in (gprof): Depend on $(LIBS).
660 Fri May 27 12:24:57 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
662 From binutils-2.4 release:
664 Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
666 * configure.bat: [new] build makefile from makefile.in (dos)

672 Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
674 * Makefile.in (.m.c:): Added .SUFFIXES : .m
675 so flat_bl.c would make from flat_bl.m file.
677 Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
679 * Makefile.in (install-info): Check for gprof.info in build dir,
680 fall back to srcdir. Depend on it.
682 * gprof.h (TRUE, FALSE): Always use undef before defining them.
684 Mon Apr 4 23:47:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
686 * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
687 makes (osf1) in which the value of MACHINE can not be changed.
688 * config/*.mt: Changed appropriately.
690 Wed Mar 30 16:12:40 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
692 * gprof.c (getsymtab): Change nosyms to long. Rename
693 get_symtab_upper_bound to bfd_get_symtab_upper_bound. Check for
694 errors from bfd_get_symtab_upper_bound and

697 Tue Mar 22 10:50:52 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
699 * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of

726 Sun Jun 20 20:58:02 1993 Ken Raeburn (raeburn@poseidon.cygnus.com)
728 * Makefile.in: Undo 15 June change.
730 Wed Jun 16 12:54:53 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)

752 * Makefile.in (install): should not depend on install-info
754 Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)
756 * gprof.h: Include ansidecl.h before sysdep.h. Undefine hz.
758 Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
760 * M Makefile.in: Add -g to CFLAGS.
761 Ads LDFLAGS and use in place of CFLAGS where appropriate.
762 * configure.in: Make a sysdep.hlink in the same way other
763 bfd-based directories do.
764 * gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
766 * gprof.h: #include sysdep.h instead of a bunch of stuff.

769 Thu Mar 25 19:00:37 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
771 * gprof.texi: add INFO-DIR-ENTRY
773 Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
775 * Makefile.in: add installcheck target
777 Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)

790 Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
792 * Makefile.in: fix install rule for $(PROG)
794 Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
796 * gprof.1: updated SYNOPSIS to match actual behavior.
798 Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
800 * gen-c-prog.awk: New awk script, lightly changed from
801 previously deleted make-c-prog.awk. Converts a text file
802 to a c function that prints that text.
803 * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
804 Inputs to gen-c-prog.awk, containing text describing
806 * blurbs.c: Removed. Use *_bl.c instead.
807 * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
808 from *_bl.m files. Also, improve *clean rules.
809 * printgprof.c (printgprof): Usw new function names from *_bl.c.
812 Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
814 * gprof.h, gprof.c, printfgprof.c: Add support for two
815 output styles: The default is similar to the old FSF gprof,
816 while -T sets the variable bsd_style_output, which causes
817 output matching Berkeley's gprof. The biggest differences
818 are that with the FSF style output, the flat profile comes
819 before the call graph; numbers come before explanations;
820 and there is less gratuitous white space.
821 * gprof.h, gprof.c, printfgprof.c: New discard_underscores
822 variable causes discarding of initial underscores when
823 printing symbol names. It is set unless there is a "main"
824 symbol (without an underscore).
825 * printfgprof.c: New function printnameonly(), called
826 by printname(). It handles stripping of initial '_',
827 as well as C++ name-demangling.
828 * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
829 It is just as convenient to edit blurbs.c directly.
830 * Makefile.in: Removed rule for making blurbs.c.
831 * blurbs.c: This is now a true source file (as opposed
832 to being generated from gprof.callg and gprof.flat).
833 Change style to use one long string literal, instead of
834 one literal per output line. Add FSF-style blurb for call graph.
836 Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
838 * Makefile.in: always create installation directories.
840 Wed Aug 12 15:14:14 1992 Mark Eichin (eichin@cygnus.com)
842 * Makefile.in: change ${MACHINE} to $(MACHINE).
844 Sun Jul 19 17:34:01 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
846 * Makefile.in: removed installation of the now useless
847 call.{flag,callg} files.
849 * gprof.1: now uses the standard man macros instead of the new BSD
852 Sun Jul 12 19:06:00 1992 John Gilmore (gnu at cygnus.com)
854 * configure.in: Remove host section, expand target section.
855 * config/mt-{tahoe,vax}: Add, to match existing support files.
856 * config/tmake-*: Remove leftover crud.
858 * blurbs.c: New file, created from gprof.flat and gprof.callg by
859 * make-c-prog.awk: which processes text files into C programs.
860 * printgprof.c (flatprofheader, gprofheader): Call new functions
862 (printblurb): Remove.
863 * Makefile.in: Infrastructure to build blurbs.
864 * pathnames.h: has been removed. Gprof now has no filename
868 Sat Jul 11 18:07:21 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
870 * Makefile.in: define man1dir and install the man page
872 Fri Jul 10 21:14:08 1992 david d `zoo' zuhn (zoo@cygnus.com)
874 * Makefile.in: added dummy info and install-info targets
876 Thu Jun 4 11:34:02 1992 Mark Eichin (eichin at cygnus.com)
878 * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
879 help in debugging the problem (with -DDEBUG)
880 * gprof.c: symbol values are now real values, don't add the vma
881 anymore. (done for solaris; should verify this on other platforms)
882 * ChangeLog: created.
