 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.
 370
 371         (GMON_Record_tag): added explicit enumeration values to ensure
 372         compatibility across compilers.
 373
 374         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 375         sizeof(char*).
 376
 377 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 378
 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.
 382
 383         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 384         binutils release.
 385
 386 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 387
 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
 392         symbol _start
 393
 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
 397         meant to be.
 398
 399         * gprof.h (File_Format): new type.
 400
 401         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 402         sync with Cygnus version numbers though...
 403
 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
 408
 409         (usage): update to reflect new options.
 410
 411         * gmon_io.c: replaced "old_file_format" by more general
 412         "file_format" option
 413
 414         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 415
 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
 419
 420         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 421         with section-relative addresses
 422
 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
 430
 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
 435
 436         * NOTES: a first shot at updating the documentation.
 437
 438 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 439
 440         * core.c (core_create_function_syms): fixed computation of min_vma
 441         and max_vma.
 442
 443         * *.c: removed rcsid.
 444
 445 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 446
 447         * Lots of changes from David Mosberger-Tang:
 448
 449         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 450
 451         * gprof.c (main): put parentheses around & within &&.
 452
 453         * basic_blocks.c (bb_read_rec): print warning message (once) when
 454         ignoring basic-block execution counts.
 455
 456         * source.c (source_file_lookup_name): corrected second argument to
 457         strcmp().
 458
 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.
 461
 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.
 465
 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.
 468
 469         * core.c: minor fixes and debugging info changes.
 470
 471         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 472
 473         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 474         name of the text-section under HP-UX).
 475
 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 /=
 479         hist_num_bins - 1".
 480
 481         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 482         hist_num_bins.
 483
 484         * configure.in: added alpha-*-*) for per-target config.
 485
 486         * alpha.c, alpha.h: created.
 487
 488         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 489
 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
 495         text-space.
 496
 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
 500         available still.
 501
 502         * utils.c (print_name_only): support for print_path added.
 503
 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.
 507
 508         * sparc.c (find_call): many fixes---this function was rather
 509         botched in binutils-2.4 already; it should work again.
 510
 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
 513         pointers).
 514
 515         * search_list.c (search_list_append): added cast for xmalloc().
 516
 517         * hist.c: added explicit initialization to some of the global
 518         variables; fixed SItab (scales were off by a factor of 10).
 519
 520         * hist.h: include of bfd.h added.
 521
 522         * gprof.c, gprof.h (print_path): added.
 523
 524         * gprof.h (MAX): fixed.
 525
 526         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 527
 528         * gmon_io.c: added some casts to (long) so we can always print as %lx
 529
 530         * core.c (core_get_text_space): fixed to make it work.
 531
 532         * cg_print.c (cg_print_index): added support for print_path option.
 533
 534         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 535
 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)
 538
 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.
 541
 542         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 543
 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.
 548
 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.
 552
 553         * gprof.h (SRCDEBUG): added.
 554
 555         * search_list.c (search_list_append): directories were added in wrong
 556         order.
 557
 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:
 562
 563           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 564           arc == spec/spec.
 565
 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.
 570
 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)
 579
 580         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 581
 582         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 583
 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.
 588
 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
 598           dimension).
 599
 600         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 601
 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
 610
 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
 615           raeburn@cygnus.com)
 616
 617         * gprof.c (usage): fixed location of --new-file-format option.
 618
 619         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 620
 621         * flat_bl.m: removed formfeed at end of file; the form-feed
 622           is now printed cg_print.c only when necessary.
 623
 624         * major rewrite of gprof---too many changes to mention all of
 625           them.  new features:
 626
 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
 630            of one per function)
 631
 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
 638           fashion
 639
 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
 643           tcov used to do
 644
 645         + long options
 646
 647         + new scheme to suppress symbols that aren't function names
 648           (e.g., avoids mistaking a goto label as a function)
 649
 650         + reorganized source code to make it more managable; as a
 651           side effect, gprof now compiles cleanly with "gcc -Wall"
 652
 653         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 654
 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.
 658
 659         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 660
 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.
 664
 665         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 666
 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.
 671
 672         * gprof.c (main): -A is now followed by a string of option chars.
 673
 674         * basic_blocks.c (annotate_with_count): replaced b->count with
 675         cnt.
 676
 677         * source.c: flag_annotate_source replaced by source_lock_map.
 678
 679         * source.h: source_lock_map added.
 680
 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
 684         are annotated.
 685
 686         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 687
 688         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 689
 690         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 691         so s_lowpc etc. get declared.
 692
 693         * arcs.h (doarcs): created.
 694
 695         * arcs.c: reordered static functions such that they get defined
 696         before use.
 697
 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)
 704
 705         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 706         source.o time_hist.o
 707
 708         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 709
 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
 713         bit doubles.
 714
 715 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 716
 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>.
 720
 721 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>

 889
 890 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 891
 892         * gprof.1: updated SYNOPSIS to match actual behavior.
 893
 894 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 895
 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
 901         gprof output.
 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.
 906
 907
 908 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 909
 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.
 931
 932 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 933
 934         * Makefile.in: always create installation directories.

 936 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)

 943         call.{flag,callg} files.
 944
 945         * gprof.1: now uses the standard man macros instead of the new BSD
 946         mandoc macros.
 947
 948 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 949
 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.
 953
 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
 957         to print blurbs.
 958         (printblurb):  Remove.
 959         * Makefile.in:  Infrastructure to build blurbs.
 960         * pathnames.h:  has been removed.  Gprof now has no filename
 961         dependencies in it.
 962         * gprof.c:  Lint.
 963

 971
 972 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 973
 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.
