 222
 223         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do

 338         that bfd_vma is only guaranteed to be at least as big as a pointer.
 339
 340         (GMON_Record_tag): added explicit enumeration values to ensure
 341         compatibility across compilers.
 342
 343         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by

 355 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 356
 357         * symtab.c (symtab_finalize): ensure globals symbols really
 358         are favored over static ones---even if their name looks less
 359         preferable; this is important for HP-UX; for example, there
 360         is a static label Ltext_something that aliases the global
 361         symbol _start
 362
 363         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 364         output only; also, auto-scaling is now performed based on
 365         per-call, rather than total execution time, which is what it was
 366         meant to be.
 367
 368         * gprof.h (File_Format): new type.
 369
 370         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 371         sync with Cygnus version numbers though...
 372
 373         (long_options): renamed --gmon-info to --file-info, --width added,
 374         renamed --old-file-format to --file-format
 375         (main): dito; also added support to read prof files, but as
 376         mon_out_read() is not implemented, it's #ifdef'd out for now
 377
 378         (usage): update to reflect new options.
 379
 380         * gmon_io.c: replaced "old_file_format" by more general
 381         "file_format" option
 382
 383         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 384
 385         * core.c (core_sym_class): added back check for __gnu_compiled and
 386         ___gnu_compiled for the benefit of systems without
 387         bfd_find_nearest_line() support
 388
 389         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 390         with section-relative addresses
 391
 392         (core_create_function_syms): get_src_info() calls are currently
 393         enabled for OSF/1 only.  It appears to work allright for SunOS
 394         4.1.x as well, but on SPARCs it gets painfully slow with the
 395         current implementation of aout_32_find_nearest_line();
 396         unfortunately, this means that static functions will not have their
 397         filename printed in the call-graph function index; line-level
 398         profiling should still work, but requires some patience
 399
 400         * cg_print.c (cg_print_index): sanitized printing of index when
 401         using FSF-style output; in particular, output width is now controlled
 402         via option --width and the function tries hard to keep columns
 403         aligned even in the presence of (occasional) long names
 404
 405         * NOTES: a first shot at updating the documentation.
 406
 407 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 408
 409         * core.c (core_create_function_syms): fixed computation of min_vma
 410         and max_vma.
 411
 412         * *.c: removed rcsid.
 413
 414 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 415
 416         * Lots of changes from David Mosberger-Tang:
 417
 418         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 419
 420         * gprof.c (main): put parentheses around & within &&.
 421
 422         * basic_blocks.c (bb_read_rec): print warning message (once) when
 423         ignoring basic-block execution counts.
 424
 425         * source.c (source_file_lookup_name): corrected second argument to
 426         strcmp().
 427
 428         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 429         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 430
 431         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 432         supported both for old and new (versioned) gmon.out files.  Old
 433         files are identified as version 0.
 434
 435         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 436         long (instead of 4) because that is what OSF/1 v3.0 uses.
 437
 438         * core.c: minor fixes and debugging info changes.
 439
 440         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 441
 442         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 443         name of the text-section under HP-UX).
 444
 445         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 446         points one past the last sampling bin, so hist_scale should be
 447         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 448         hist_num_bins - 1".
 449
 450         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 451         hist_num_bins.
 452
 453         * configure.in: added alpha-*-*) for per-target config.
 454
 455         * alpha.c, alpha.h: created.
 456
 457         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 458
 459         * core.c (core_create_function_syms, core_create_line_syms):
 460         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 461         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 462         addr) continues to guarantee not to return 0 on any address.  It
 463         also avoids incorrectly crediting the first/last symbol in the
 464         text-space.
 465
 466         * core.c (core_create_line_syms): always create function symbols
 467         first, then merge in line symbols; this is so that if parts of the
 468         program were compiled without -g, function-level symbols are
 469         available still.
 470
 471         * utils.c (print_name_only): support for print_path added.
 472
 473         * symtab.c (cmp_addr): also use is_func flag in comparison.
 474         (symtab_finalize): return immediately when table empty; now
 475         more careful about getting rid of the right duplicate symbol.
 476
 477         * sparc.c (find_call): many fixes---this function was rather
 478         botched in binutils-2.4 already; it should work again.
 479
 480         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 481         not good to rely on get_src_info() to return distinct string
 482         pointers).
 483
 484         * search_list.c (search_list_append): added cast for xmalloc().
 485
 486         * hist.c: added explicit initialization to some of the global
 487         variables; fixed SItab (scales were off by a factor of 10).
 488
 489         * hist.h: include of bfd.h added.
 490
 491         * gprof.c, gprof.h (print_path): added.
 492
 493         * gprof.h (MAX): fixed.
 494
 495         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 496
 497         * gmon_io.c: added some casts to (long) so we can always print as %lx
 498
 499         * core.c (core_get_text_space): fixed to make it work.
 500
 501         * cg_print.c (cg_print_index): added support for print_path option.
 502
 503         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 504
 505         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 506         as some compilers complain (e.g., DEC's OSF/1 compiler)
 507
 508         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 509         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 510
 511         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 512
 513         * gprof.c: added "_mcount" to default_excluded_list.
 514         (main): if output_style==0 and there is either a histogram or a
 515         call-graph, always generate flat and call-graph, no matter what
 516         line_granularity is set to.
 517
 518         * source.c (source_file_lookup_name): if searching for sf->name
 519         fails, try again with filename obtained after stripping off any
 520         partial path from sf->name.
 521
 522         * gprof.h (SRCDEBUG): added.
 523
 524         * search_list.c (search_list_append): directories were added in wrong
 525         order.
 526
 527         * reimplemented selection mechanism from ground up; it is now possible
 528         to accurately control what gets included/excluded in each of the
 529         output styles;  a "symbol-specification" (spec) is the basic means
 530         to select a set of symbols; a spec has the syntax:
 531
 532           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 533           arc == spec/spec.
 534
 535         any of the terminal symbols can be empty, in which case they
 536         match anything (wildcards).  NAME is interpreted as a FILENAME
 537         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 538         with a digit, and as FUNCNAME otherwise.
 539
 540         For example, to get a call-graph display that ignores arcs
 541         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 542         show only arcs into bar() (no matter what the caller),
 543         you'd say "--graph=/bar"; and to get a call-graph without
 544         any arc info, you'd say "--graph=/";  similarly, to
 545         get a flat profile without mcount, you'd say "--no-flat=mcount"
 546         and to get a flat profile that shows includes all functions
 547         you'd say "--flat=""" (i.e., an empty spec)
 548
 549         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 550
 551         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 552
 553         * gmon_out.h: all headers now declared in terms of characters
 554           to avoid getting into trouble with different compilers introducing
 555           different amount of padding; the code already accessed the fields
 556           through bfd functions, so that didn't have to change.
 557
 558         * hist.c (hist_read_rec, hist_write_rec): added support for
 559           collection pc histograms measuring quantities other than time;
 560           the histogram header now includes a field that specifies the
 561           dimension of the quantity measured by the histogram bins
 562           (normally, this is "seconds", but other meaningful dimensions
 563            include such things as "I-cache misses", "instruction issue stalls"
 564            etc.); there is also a field to specify a one-character
 565           abbreviation for the dimension; in the case of time, this would
 566           be 's'; in most other cases it probably would be '1' (not a physical
 567           dimension).
 568
 569         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 570
 571         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 572           has become old_file_version; gmon_io.c now always supports old-style
 573           gmon.out files; it first tries to read gmon.out as a new version
 574           file, if that fails, it tries to read it in the old format;
 575           although not very likely, it is possible for gprof to mistake an
 576           old-style file as a new one (the first 4 bytes would have to
 577           be "gmon"---including the trailing '\0'); in that case, it is
 578           necessary to specify --old-file-version
 579
 580         * gprof.h: removed dependency on SYSV; the code now always uses
 581           strrchr(), memset(), and memcpy() and does not include either
 582           of string.h or strings.h; this should make gprof compile on
 583           any (Unix) system without configuration (per suggestion of
 584           raeburn@cygnus.com)
 585
 586         * gprof.c (usage): fixed location of --new-file-format option.
 587
 588         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 589
 590         * flat_bl.m: removed formfeed at end of file; the form-feed
 591           is now printed cg_print.c only when necessary.
 592
 593         * major rewrite of gprof---too many changes to mention all of
 594           them.  new features:
 595
 596         + -l now requests profiling at the line level (as opposed
 597           to function level); in this mode, gprof creates a "symbol"
 598           (aka name-list entry) for each line of source code, instead
 599            of one per function)
 600
 601         + support for a new gmon.out file format; the new format
 602           consists of a header with a magic and a version number,
 603           followed by a sequence of profile data; profile data
 604           can any of: (a) PC histogram, (b) call-graph arcs, or
 605           (c) basic-block execution counts; the version number makes
 606           it possible to extend gmon.out in a backwards compatible
 607           fashion
 608
 609         + support for tcov style annotated output: if the gmon.out file
 610           contains basic-block execution counts, the user can request
 611           the generation of annotated source files, much like Sun's
 612           tcov used to do
 613
 614         + long options
 615
 616         + new scheme to suppress symbols that aren't function names
 617           (e.g., avoids mistaking a goto label as a function)
 618
 619         + reorganized source code to make it more managable; as a
 620           side effect, gprof now compiles cleanly with "gcc -Wall"
 621
 622         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 623
 624         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 625         final cross-check to determine whether a static symbol should be
 626         considered as a function-name.
 627
 628         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 629
 630         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 631         stdin; this is useful if you wanna keep gmon.out files compressed;
 632         this way you can "gzcat" the compressed file into gprof.
 633
 634         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 635
 636         * basic_blocks.c (bb_annotate_source): added support for creating
 637         .tcov files when option flag_annotate_make_files is TRUE.
 638         (annotate_with_count): all counts less than the minimum count
 639         specified by -m are now annotated with hash-marks.
 640
 641         * gprof.c (main): -A is now followed by a string of option chars.
 642
 643         * basic_blocks.c (annotate_with_count): replaced b->count with
 644         cnt.
 645
 646         * source.c: flag_annotate_source replaced by source_lock_map.
 647
 648         * source.h: source_lock_map added.
 649
 650         * gprof.c (main): new command-line syntax: -S simply specifies
 651         which source-files user is interested in; -A requests annotated
 652         source files and -AA requests that all lines in a source file
 653         are annotated.
 654
 655         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 656
 657         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 658
 659         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 660         so s_lowpc etc. get declared.
 661
 662         * arcs.h (doarcs): created.
 663
 664         * arcs.c: reordered static functions such that they get defined
 665         before use.
 666
 667         * gprof.c (main): added options:
 668            -A: request annotation of all source lines (with -S)
 669            -m: minimum execution count (with default basic-block display)
 670            -N: force new file format (only if BSD_COMPATIBLE is defined)
 671            -S: annotate source file
 672            -t: set table length (with -S)
 673
 674         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 675         source.o time_hist.o
 676
 677         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 678
 679         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 680         on the fact being able to store a long in a double without loss of
 681         precision; this does not hold on machines with 64 bit longs and 64
 682         bit doubles.
 683
 684 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 685
 686         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 687         greater than 0.0.  Suggested by Harold Assink
 688         <carlo@sg.tn.tudelft.nl>.
 689
 690 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 691
 692         * printgprof.c (printprof): Use free, not cfree.
 693         (printgprof, printindex): Ditto.
 694
 695 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 696
 697         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 698         decls extern to keep native HP compiler quiet.
 699
 700 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 701
 702         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 703         __gnu_compiled, for the benefit of systems which add a leading
 704         underscore.
 705
 706 Wed Aug 24 12:49:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 707
 708         * configure.in: Change i386-*-* to i[345]86-*-*.
 709
 710 Sun Jul 10 00:35:31 1994  Ian Dall  (dall@hfrd.dsto.gov.au)
 711
 712         * ns532.c, ns532.h: New Files. ns532 support.
 713
 714         * config/mt-ns532: New File. ns532 support.
 715
 716         * gprof.c: user register int i instead of defaulting the int.
 717         Allows compilation with -Dregister= for debugging.
 718

 858
 859 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 860
 861         * gprof.1: updated SYNOPSIS to match actual behavior.
 862
 863 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 864
 865         * gen-c-prog.awk:  New awk script, lightly changed from
 866         previously deleted make-c-prog.awk.  Converts a text file
 867         to a c function that prints that text.
 868         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 869         Inputs to gen-c-prog.awk, containing text describing
 870         gprof output.
 871         * blurbs.c:  Removed.  Use *_bl.c instead.
 872         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 873         from *_bl.m files.  Also, improve *clean rules.
 874         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 875
 876
 877 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 878
 879         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 880         output styles:  The default is similar to the old FSF gprof,
 881         while -T sets the variable bsd_style_output, which causes
 882         output matching Berkeley's gprof.  The biggest differences
 883         are that with the FSF style output, the flat profile comes
 884         before the call graph; numbers come before explanations;
 885         and there is less gratuitous white space.
 886         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 887         variable causes discarding of initial underscores when
 888         printing symbol names.  It is set unless there is a "main"
 889         symbol (without an underscore).
 890         * printfgprof.c:  New function printnameonly(), called
 891         by printname().  It handles stripping of initial '_',
 892         as well as C++ name-demangling.
 893         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 894         It is just as convenient to edit blurbs.c directly.
 895         * Makefile.in:  Removed rule for making blurbs.c.
 896         * blurbs.c:  This is now a true source file (as opposed
 897         to being generated from gprof.callg and gprof.flat).
 898         Change style to use one long string literal, instead of
 899         one literal per output line.  Add FSF-style blurb for call graph.
 900
 901 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 902
 903         * Makefile.in: always create installation directories.
 904
 905 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 906
 907         * Makefile.in: change ${MACHINE} to $(MACHINE).

 910
 911         * Makefile.in:  removed installation of the now useless
 912         call.{flag,callg} files.
 913
 914         * gprof.1: now uses the standard man macros instead of the new BSD
 915         mandoc macros.
 916
 917 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 918
 919         * configure.in:  Remove host section, expand target section.
 920         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 921         * config/tmake-*:  Remove leftover crud.
 922
 923         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 924         * make-c-prog.awk:  which processes text files into C programs.
 925         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 926         to print blurbs.
 927         (printblurb):  Remove.
 928         * Makefile.in:  Infrastructure to build blurbs.
 929         * pathnames.h:  has been removed.  Gprof now has no filename
 930         dependencies in it.
 931         * gprof.c:  Lint.
 932

 939         * Makefile.in: added dummy info and install-info targets
 940
 941 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 942
 943         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 944         help in debugging the problem (with -DDEBUG)
 945         * gprof.c: symbol values are now real values, don't add the vma
 946         anymore. (done for solaris; should verify this on other platforms)
 947         * ChangeLog: created.
