 362
 363         * symtab.c (symtab_finalize): ensure globals symbols really
 364         are favored over static ones---even if their name looks less
 365         preferable; this is important for HP-UX; for example, there
 366         is a static label Ltext_something that aliases the global
 367         symbol _start
 368
 369         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 370         output only; also, auto-scaling is now performed based on
 371         per-call, rather than total execution time, which is what it was
 372         meant to be.
 373
 374         * gprof.h (File_Format): new type.
 375
 376         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 377         sync with Cygnus version numbers though...
 378
 379         (long_options): renamed --gmon-info to --file-info, --width added,
 380         renamed --old-file-format to --file-format
 381         (main): dito; also added support to read prof files, but as
 382         mon_out_read() is not implemented, it's #ifdef'd out for now
 383
 384         (usage): update to reflect new options.
 385
 386         * gmon_io.c: replaced "old_file_format" by more general
 387         "file_format" option
 388
 389         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 390
 391         * core.c (core_sym_class): added back check for __gnu_compiled and
 392         ___gnu_compiled for the benefit of systems without
 393         bfd_find_nearest_line() support
 394
 395         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 396         with section-relative addresses
 397
 398         (core_create_function_syms): get_src_info() calls are currently
 399         enabled for OSF/1 only.  It appears to work allright for SunOS
 400         4.1.x as well, but on SPARCs it gets painfully slow with the
 401         current implementation of aout_32_find_nearest_line();
 402         unfortunately, this means that static functions will not have their
 403         filename printed in the call-graph function index; line-level
 404         profiling should still work, but requires some patience
 405
 406         * cg_print.c (cg_print_index): sanitized printing of index when
 407         using FSF-style output; in particular, output width is now controlled
 408         via option --width and the function tries hard to keep columns
 409         aligned even in the presence of (occasional) long names
 410
 411         * NOTES: a first shot at updating the documentation.
 412
 413 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 414
 415         * core.c (core_create_function_syms): fixed computation of min_vma
 416         and max_vma.
 417
 418         * *.c: removed rcsid.
 419
 420 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 421
 422         * Lots of changes from David Mosberger-Tang:
 423
 424         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 425
 426         * gprof.c (main): put parentheses around & within &&.
 427
 428         * basic_blocks.c (bb_read_rec): print warning message (once) when
 429         ignoring basic-block execution counts.
 430
 431         * source.c (source_file_lookup_name): corrected second argument to
 432         strcmp().
 433
 434         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 435         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 436
 437         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 438         supported both for old and new (versioned) gmon.out files.  Old
 439         files are identified as version 0.
 440
 441         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 442         long (instead of 4) because that is what OSF/1 v3.0 uses.
 443
 444         * core.c: minor fixes and debugging info changes.
 445
 446         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 447
 448         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 449         name of the text-section under HP-UX).
 450
 451         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 452         points one past the last sampling bin, so hist_scale should be
 453         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 454         hist_num_bins - 1".
 455
 456         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 457         hist_num_bins.
 458
 459         * configure.in: added alpha-*-*) for per-target config.
 460
 461         * alpha.c, alpha.h: created.
 462
 463         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 464
 465         * core.c (core_create_function_syms, core_create_line_syms):
 466         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 467         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 468         addr) continues to guarantee not to return 0 on any address.  It
 469         also avoids incorrectly crediting the first/last symbol in the
 470         text-space.
 471
 472         * core.c (core_create_line_syms): always create function symbols
 473         first, then merge in line symbols; this is so that if parts of the
 474         program were compiled without -g, function-level symbols are
 475         available still.
 476
 477         * utils.c (print_name_only): support for print_path added.
 478
 479         * symtab.c (cmp_addr): also use is_func flag in comparison.
 480         (symtab_finalize): return immediately when table empty; now
 481         more careful about getting rid of the right duplicate symbol.
 482
 483         * sparc.c (find_call): many fixes---this function was rather
 484         botched in binutils-2.4 already; it should work again.
 485
 486         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 487         not good to rely on get_src_info() to return distinct string
 488         pointers).
 489
 490         * search_list.c (search_list_append): added cast for xmalloc().
 491
 492         * hist.c: added explicit initialization to some of the global
 493         variables; fixed SItab (scales were off by a factor of 10).
 494
 495         * hist.h: include of bfd.h added.
 496
 497         * gprof.c, gprof.h (print_path): added.
 498
 499         * gprof.h (MAX): fixed.
 500
 501         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 502
 503         * gmon_io.c: added some casts to (long) so we can always print as %lx
 504
 505         * core.c (core_get_text_space): fixed to make it work.
 506
 507         * cg_print.c (cg_print_index): added support for print_path option.
 508
 509         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 510
 511         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 512         as some compilers complain (e.g., DEC's OSF/1 compiler)
 513
 514         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 515         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 516
 517         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 518
 519         * gprof.c: added "_mcount" to default_excluded_list.
 520         (main): if output_style==0 and there is either a histogram or a
 521         call-graph, always generate flat and call-graph, no matter what
 522         line_granularity is set to.
 523
 524         * source.c (source_file_lookup_name): if searching for sf->name
 525         fails, try again with filename obtained after stripping off any
 526         partial path from sf->name.
 527
 528         * gprof.h (SRCDEBUG): added.
 529
 530         * search_list.c (search_list_append): directories were added in wrong
 531         order.
 532
 533         * reimplemented selection mechanism from ground up; it is now possible
 534         to accurately control what gets included/excluded in each of the
 535         output styles;  a "symbol-specification" (spec) is the basic means
 536         to select a set of symbols; a spec has the syntax:
 537
 538           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 539           arc == spec/spec.
 540
 541         any of the terminal symbols can be empty, in which case they
 542         match anything (wildcards).  NAME is interpreted as a FILENAME
 543         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 544         with a digit, and as FUNCNAME otherwise.
 545
 546         For example, to get a call-graph display that ignores arcs
 547         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 548         show only arcs into bar() (no matter what the caller),
 549         you'd say "--graph=/bar"; and to get a call-graph without
 550         any arc info, you'd say "--graph=/";  similarly, to
 551         get a flat profile without mcount, you'd say "--no-flat=mcount"
 552         and to get a flat profile that shows includes all functions
 553         you'd say "--flat=""" (i.e., an empty spec)
 554
 555         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 556
 557         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 558
 559         * gmon_out.h: all headers now declared in terms of characters
 560           to avoid getting into trouble with different compilers introducing
 561           different amount of padding; the code already accessed the fields
 562           through bfd functions, so that didn't have to change.
 563
 564         * hist.c (hist_read_rec, hist_write_rec): added support for
 565           collection pc histograms measuring quantities other than time;
 566           the histogram header now includes a field that specifies the
 567           dimension of the quantity measured by the histogram bins
 568           (normally, this is "seconds", but other meaningful dimensions
 569            include such things as "I-cache misses", "instruction issue stalls"
 570            etc.); there is also a field to specify a one-character
 571           abbreviation for the dimension; in the case of time, this would
 572           be 's'; in most other cases it probably would be '1' (not a physical
 573           dimension).
 574
 575         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 576
 577         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 578           has become old_file_version; gmon_io.c now always supports old-style
 579           gmon.out files; it first tries to read gmon.out as a new version
 580           file, if that fails, it tries to read it in the old format;
 581           although not very likely, it is possible for gprof to mistake an
 582           old-style file as a new one (the first 4 bytes would have to
 583           be "gmon"---including the trailing '\0'); in that case, it is
 584           necessary to specify --old-file-version
 585
 586         * gprof.h: removed dependency on SYSV; the code now always uses
 587           strrchr(), memset(), and memcpy() and does not include either
 588           of string.h or strings.h; this should make gprof compile on
 589           any (Unix) system without configuration (per suggestion of
 590           raeburn@cygnus.com)
 591
 592         * gprof.c (usage): fixed location of --new-file-format option.
 593
 594         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 595
 596         * flat_bl.m: removed formfeed at end of file; the form-feed
 597           is now printed cg_print.c only when necessary.
 598
 599         * major rewrite of gprof---too many changes to mention all of
 600           them.  new features:
 601
 602         + -l now requests profiling at the line level (as opposed
 603           to function level); in this mode, gprof creates a "symbol"
 604           (aka name-list entry) for each line of source code, instead
 605            of one per function)
 606
 607         + support for a new gmon.out file format; the new format
 608           consists of a header with a magic and a version number,
 609           followed by a sequence of profile data; profile data
 610           can any of: (a) PC histogram, (b) call-graph arcs, or
 611           (c) basic-block execution counts; the version number makes
 612           it possible to extend gmon.out in a backwards compatible
 613           fashion
 614
 615         + support for tcov style annotated output: if the gmon.out file
 616           contains basic-block execution counts, the user can request
 617           the generation of annotated source files, much like Sun's
 618           tcov used to do
 619
 620         + long options
 621
 622         + new scheme to suppress symbols that aren't function names
 623           (e.g., avoids mistaking a goto label as a function)
 624
 625         + reorganized source code to make it more managable; as a
 626           side effect, gprof now compiles cleanly with "gcc -Wall"
 627
 628         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 629
 630         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 631         final cross-check to determine whether a static symbol should be
 632         considered as a function-name.
 633
 634         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 635
 636         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 637         stdin; this is useful if you wanna keep gmon.out files compressed;
 638         this way you can "gzcat" the compressed file into gprof.
 639
 640         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 641
 642         * basic_blocks.c (bb_annotate_source): added support for creating
 643         .tcov files when option flag_annotate_make_files is TRUE.
 644         (annotate_with_count): all counts less than the minimum count
 645         specified by -m are now annotated with hash-marks.
 646
 647         * gprof.c (main): -A is now followed by a string of option chars.
 648
 649         * basic_blocks.c (annotate_with_count): replaced b->count with
 650         cnt.
 651
 652         * source.c: flag_annotate_source replaced by source_lock_map.
 653
 654         * source.h: source_lock_map added.
 655
 656         * gprof.c (main): new command-line syntax: -S simply specifies
 657         which source-files user is interested in; -A requests annotated
 658         source files and -AA requests that all lines in a source file
 659         are annotated.
 660
 661         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 662
 663         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 664
 665         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 666         so s_lowpc etc. get declared.
 667
 668         * arcs.h (doarcs): created.
 669
 670         * arcs.c: reordered static functions such that they get defined
 671         before use.
 672
 673         * gprof.c (main): added options:
 674            -A: request annotation of all source lines (with -S)
 675            -m: minimum execution count (with default basic-block display)
 676            -N: force new file format (only if BSD_COMPATIBLE is defined)
 677            -S: annotate source file
 678            -t: set table length (with -S)
 679
 680         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 681         source.o time_hist.o
 682
 683         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 684
 685         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 686         on the fact being able to store a long in a double without loss of
 687         precision; this does not hold on machines with 64 bit longs and 64
 688         bit doubles.
 689
 690 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 691
 692         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 693         greater than 0.0.  Suggested by Harold Assink
 694         <carlo@sg.tn.tudelft.nl>.
 695
 696 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 697
 698         * printgprof.c (printprof): Use free, not cfree.
 699         (printgprof, printindex): Ditto.
 700
 701 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 702
 703         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 704         decls extern to keep native HP compiler quiet.
 705
 706 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 707
 708         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 709         __gnu_compiled, for the benefit of systems which add a leading
 710         underscore.
 711
 712 Wed Aug 24 12:49:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 713
 714         * configure.in: Change i386-*-* to i[345]86-*-*.
 715
 716 Sun Jul 10 00:35:31 1994  Ian Dall  (dall@hfrd.dsto.gov.au)
 717
 718         * ns532.c, ns532.h: New Files. ns532 support.
 719

 866
 867         * gprof.1: updated SYNOPSIS to match actual behavior.
 868
 869 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 870
 871         * gen-c-prog.awk:  New awk script, lightly changed from
 872         previously deleted make-c-prog.awk.  Converts a text file
 873         to a c function that prints that text.
 874         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 875         Inputs to gen-c-prog.awk, containing text describing
 876         gprof output.
 877         * blurbs.c:  Removed.  Use *_bl.c instead.
 878         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 879         from *_bl.m files.  Also, improve *clean rules.
 880         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 881
 882
 883 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 884
 885         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 886         output styles:  The default is similar to the old FSF gprof,
 887         while -T sets the variable bsd_style_output, which causes
 888         output matching Berkeley's gprof.  The biggest differences
 889         are that with the FSF style output, the flat profile comes
 890         before the call graph; numbers come before explanations;
 891         and there is less gratuitous white space.
 892         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 893         variable causes discarding of initial underscores when
 894         printing symbol names.  It is set unless there is a "main"
 895         symbol (without an underscore).
 896         * printfgprof.c:  New function printnameonly(), called
 897         by printname().  It handles stripping of initial '_',
 898         as well as C++ name-demangling.
 899         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 900         It is just as convenient to edit blurbs.c directly.
 901         * Makefile.in:  Removed rule for making blurbs.c.
 902         * blurbs.c:  This is now a true source file (as opposed
 903         to being generated from gprof.callg and gprof.flat).
 904         Change style to use one long string literal, instead of
 905         one literal per output line.  Add FSF-style blurb for call graph.
 906
 907 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 908
 909         * Makefile.in: always create installation directories.
 910
 911 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 912
 913         * Makefile.in: change ${MACHINE} to $(MACHINE).

 916
 917         * Makefile.in:  removed installation of the now useless
 918         call.{flag,callg} files.
 919
 920         * gprof.1: now uses the standard man macros instead of the new BSD
 921         mandoc macros.
 922
 923 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 924
 925         * configure.in:  Remove host section, expand target section.
 926         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 927         * config/tmake-*:  Remove leftover crud.
 928
 929         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 930         * make-c-prog.awk:  which processes text files into C programs.
 931         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 932         to print blurbs.
 933         (printblurb):  Remove.
 934         * Makefile.in:  Infrastructure to build blurbs.
 935         * pathnames.h:  has been removed.  Gprof now has no filename
 936         dependencies in it.
 937         * gprof.c:  Lint.
 938

 946
 947 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 948
 949         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 950         help in debugging the problem (with -DDEBUG)
 951         * gprof.c: symbol values are now real values, don't add the vma
 952         anymore. (done for solaris; should verify this on other platforms)
 953         * ChangeLog: created.
