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

 870
 871         * gprof.1: updated SYNOPSIS to match actual behavior.
 872
 873 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 874
 875         * gen-c-prog.awk:  New awk script, lightly changed from
 876         previously deleted make-c-prog.awk.  Converts a text file
 877         to a c function that prints that text.
 878         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 879         Inputs to gen-c-prog.awk, containing text describing
 880         gprof output.
 881         * blurbs.c:  Removed.  Use *_bl.c instead.
 882         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 883         from *_bl.m files.  Also, improve *clean rules.
 884         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 885
 886
 887 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 888
 889         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 890         output styles:  The default is similar to the old FSF gprof,
 891         while -T sets the variable bsd_style_output, which causes
 892         output matching Berkeley's gprof.  The biggest differences
 893         are that with the FSF style output, the flat profile comes
 894         before the call graph; numbers come before explanations;
 895         and there is less gratuitous white space.
 896         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 897         variable causes discarding of initial underscores when
 898         printing symbol names.  It is set unless there is a "main"
 899         symbol (without an underscore).
 900         * printfgprof.c:  New function printnameonly(), called
 901         by printname().  It handles stripping of initial '_',
 902         as well as C++ name-demangling.
 903         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 904         It is just as convenient to edit blurbs.c directly.
 905         * Makefile.in:  Removed rule for making blurbs.c.
 906         * blurbs.c:  This is now a true source file (as opposed
 907         to being generated from gprof.callg and gprof.flat).
 908         Change style to use one long string literal, instead of
 909         one literal per output line.  Add FSF-style blurb for call graph.
 910
 911 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 912
 913         * Makefile.in: always create installation directories.
 914
 915 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 916
 917         * Makefile.in: change ${MACHINE} to $(MACHINE).

 920
 921         * Makefile.in:  removed installation of the now useless
 922         call.{flag,callg} files.
 923
 924         * gprof.1: now uses the standard man macros instead of the new BSD
 925         mandoc macros.
 926
 927 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 928
 929         * configure.in:  Remove host section, expand target section.
 930         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 931         * config/tmake-*:  Remove leftover crud.
 932
 933         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 934         * make-c-prog.awk:  which processes text files into C programs.
 935         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 936         to print blurbs.
 937         (printblurb):  Remove.
 938         * Makefile.in:  Infrastructure to build blurbs.
 939         * pathnames.h:  has been removed.  Gprof now has no filename
 940         dependencies in it.
 941         * gprof.c:  Lint.
 942

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