 367         compatibility across compilers.
 368
 369         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 370         sizeof(char*).
 371
 372 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 373
 374         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 375         of constructs GNU indent couldn't handle.  Block comments not yet
 376         rewritten in GNU format.
 377
 378         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 379         binutils release.
 380
 381 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 382
 383         * symtab.c (symtab_finalize): ensure globals symbols really
 384         are favored over static ones---even if their name looks less
 385         preferable; this is important for HP-UX; for example, there
 386         is a static label Ltext_something that aliases the global
 387         symbol _start
 388
 389         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 390         output only; also, auto-scaling is now performed based on
 391         per-call, rather than total execution time, which is what it was
 392         meant to be.
 393
 394         * gprof.h (File_Format): new type.
 395
 396         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 397         sync with Cygnus version numbers though...
 398
 399         (long_options): renamed --gmon-info to --file-info, --width added,
 400         renamed --old-file-format to --file-format
 401         (main): dito; also added support to read prof files, but as
 402         mon_out_read() is not implemented, it's #ifdef'd out for now
 403
 404         (usage): update to reflect new options.
 405
 406         * gmon_io.c: replaced "old_file_format" by more general
 407         "file_format" option
 408
 409         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 410
 411         * core.c (core_sym_class): added back check for __gnu_compiled and
 412         ___gnu_compiled for the benefit of systems without
 413         bfd_find_nearest_line() support
 414
 415         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 416         with section-relative addresses
 417
 418         (core_create_function_syms): get_src_info() calls are currently
 419         enabled for OSF/1 only.  It appears to work allright for SunOS
 420         4.1.x as well, but on SPARCs it gets painfully slow with the
 421         current implementation of aout_32_find_nearest_line();
 422         unfortunately, this means that static functions will not have their
 423         filename printed in the call-graph function index; line-level
 424         profiling should still work, but requires some patience
 425
 426         * cg_print.c (cg_print_index): sanitized printing of index when
 427         using FSF-style output; in particular, output width is now controlled
 428         via option --width and the function tries hard to keep columns
 429         aligned even in the presence of (occasional) long names
 430
 431         * NOTES: a first shot at updating the documentation.
 432
 433 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 434
 435         * core.c (core_create_function_syms): fixed computation of min_vma
 436         and max_vma.
 437
 438         * *.c: removed rcsid.
 439
 440 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 441
 442         * Lots of changes from David Mosberger-Tang:
 443
 444         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 445
 446         * gprof.c (main): put parentheses around & within &&.
 447
 448         * basic_blocks.c (bb_read_rec): print warning message (once) when
 449         ignoring basic-block execution counts.
 450
 451         * source.c (source_file_lookup_name): corrected second argument to
 452         strcmp().
 453
 454         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 455         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 456
 457         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 458         supported both for old and new (versioned) gmon.out files.  Old
 459         files are identified as version 0.
 460
 461         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 462         long (instead of 4) because that is what OSF/1 v3.0 uses.
 463
 464         * core.c: minor fixes and debugging info changes.
 465
 466         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 467
 468         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 469         name of the text-section under HP-UX).
 470
 471         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 472         points one past the last sampling bin, so hist_scale should be
 473         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 474         hist_num_bins - 1".
 475
 476         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 477         hist_num_bins.
 478
 479         * configure.in: added alpha-*-*) for per-target config.
 480
 481         * alpha.c, alpha.h: created.
 482
 483         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 484
 485         * core.c (core_create_function_syms, core_create_line_syms):
 486         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 487         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 488         addr) continues to guarantee not to return 0 on any address.  It
 489         also avoids incorrectly crediting the first/last symbol in the
 490         text-space.
 491
 492         * core.c (core_create_line_syms): always create function symbols
 493         first, then merge in line symbols; this is so that if parts of the
 494         program were compiled without -g, function-level symbols are
 495         available still.
 496
 497         * utils.c (print_name_only): support for print_path added.
 498
 499         * symtab.c (cmp_addr): also use is_func flag in comparison.
 500         (symtab_finalize): return immediately when table empty; now
 501         more careful about getting rid of the right duplicate symbol.
 502
 503         * sparc.c (find_call): many fixes---this function was rather
 504         botched in binutils-2.4 already; it should work again.
 505
 506         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 507         not good to rely on get_src_info() to return distinct string
 508         pointers).
 509
 510         * search_list.c (search_list_append): added cast for xmalloc().
 511
 512         * hist.c: added explicit initialization to some of the global
 513         variables; fixed SItab (scales were off by a factor of 10).
 514
 515         * hist.h: include of bfd.h added.
 516
 517         * gprof.c, gprof.h (print_path): added.
 518
 519         * gprof.h (MAX): fixed.
 520
 521         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 522
 523         * gmon_io.c: added some casts to (long) so we can always print as %lx
 524
 525         * core.c (core_get_text_space): fixed to make it work.
 526
 527         * cg_print.c (cg_print_index): added support for print_path option.
 528
 529         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 530
 531         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 532         as some compilers complain (e.g., DEC's OSF/1 compiler)
 533
 534         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 535         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 536
 537         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 538
 539         * gprof.c: added "_mcount" to default_excluded_list.
 540         (main): if output_style==0 and there is either a histogram or a
 541         call-graph, always generate flat and call-graph, no matter what
 542         line_granularity is set to.
 543
 544         * source.c (source_file_lookup_name): if searching for sf->name
 545         fails, try again with filename obtained after stripping off any
 546         partial path from sf->name.
 547
 548         * gprof.h (SRCDEBUG): added.
 549
 550         * search_list.c (search_list_append): directories were added in wrong
 551         order.
 552
 553         * reimplemented selection mechanism from ground up; it is now possible
 554         to accurately control what gets included/excluded in each of the
 555         output styles;  a "symbol-specification" (spec) is the basic means
 556         to select a set of symbols; a spec has the syntax:
 557
 558           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 559           arc == spec/spec.
 560
 561         any of the terminal symbols can be empty, in which case they
 562         match anything (wildcards).  NAME is interpreted as a FILENAME
 563         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 564         with a digit, and as FUNCNAME otherwise.
 565
 566         For example, to get a call-graph display that ignores arcs
 567         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 568         show only arcs into bar() (no matter what the caller),
 569         you'd say "--graph=/bar"; and to get a call-graph without
 570         any arc info, you'd say "--graph=/";  similarly, to
 571         get a flat profile without mcount, you'd say "--no-flat=mcount"
 572         and to get a flat profile that shows includes all functions
 573         you'd say "--flat=""" (i.e., an empty spec)
 574
 575         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 576
 577         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 578
 579         * gmon_out.h: all headers now declared in terms of characters
 580           to avoid getting into trouble with different compilers introducing
 581           different amount of padding; the code already accessed the fields
 582           through bfd functions, so that didn't have to change.
 583
 584         * hist.c (hist_read_rec, hist_write_rec): added support for
 585           collection pc histograms measuring quantities other than time;
 586           the histogram header now includes a field that specifies the
 587           dimension of the quantity measured by the histogram bins
 588           (normally, this is "seconds", but other meaningful dimensions
 589            include such things as "I-cache misses", "instruction issue stalls"
 590            etc.); there is also a field to specify a one-character
 591           abbreviation for the dimension; in the case of time, this would
 592           be 's'; in most other cases it probably would be '1' (not a physical
 593           dimension).
 594
 595         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 596
 597         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 598           has become old_file_version; gmon_io.c now always supports old-style
 599           gmon.out files; it first tries to read gmon.out as a new version
 600           file, if that fails, it tries to read it in the old format;
 601           although not very likely, it is possible for gprof to mistake an
 602           old-style file as a new one (the first 4 bytes would have to
 603           be "gmon"---including the trailing '\0'); in that case, it is
 604           necessary to specify --old-file-version
 605
 606         * gprof.h: removed dependency on SYSV; the code now always uses
 607           strrchr(), memset(), and memcpy() and does not include either
 608           of string.h or strings.h; this should make gprof compile on
 609           any (Unix) system without configuration (per suggestion of
 610           raeburn@cygnus.com)
 611
 612         * gprof.c (usage): fixed location of --new-file-format option.
 613
 614         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 615
 616         * flat_bl.m: removed formfeed at end of file; the form-feed
 617           is now printed cg_print.c only when necessary.
 618
 619         * major rewrite of gprof---too many changes to mention all of
 620           them.  new features:
 621
 622         + -l now requests profiling at the line level (as opposed
 623           to function level); in this mode, gprof creates a "symbol"
 624           (aka name-list entry) for each line of source code, instead
 625            of one per function)
 626
 627         + support for a new gmon.out file format; the new format
 628           consists of a header with a magic and a version number,
 629           followed by a sequence of profile data; profile data
 630           can any of: (a) PC histogram, (b) call-graph arcs, or
 631           (c) basic-block execution counts; the version number makes
 632           it possible to extend gmon.out in a backwards compatible
 633           fashion
 634
 635         + support for tcov style annotated output: if the gmon.out file
 636           contains basic-block execution counts, the user can request
 637           the generation of annotated source files, much like Sun's
 638           tcov used to do
 639
 640         + long options
 641
 642         + new scheme to suppress symbols that aren't function names
 643           (e.g., avoids mistaking a goto label as a function)
 644
 645         + reorganized source code to make it more managable; as a
 646           side effect, gprof now compiles cleanly with "gcc -Wall"
 647
 648         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 649
 650         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 651         final cross-check to determine whether a static symbol should be
 652         considered as a function-name.
 653
 654         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 655
 656         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 657         stdin; this is useful if you wanna keep gmon.out files compressed;
 658         this way you can "gzcat" the compressed file into gprof.
 659
 660         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 661
 662         * basic_blocks.c (bb_annotate_source): added support for creating
 663         .tcov files when option flag_annotate_make_files is TRUE.
 664         (annotate_with_count): all counts less than the minimum count
 665         specified by -m are now annotated with hash-marks.
 666
 667         * gprof.c (main): -A is now followed by a string of option chars.
 668
 669         * basic_blocks.c (annotate_with_count): replaced b->count with
 670         cnt.
 671
 672         * source.c: flag_annotate_source replaced by source_lock_map.
 673
 674         * source.h: source_lock_map added.
 675
 676         * gprof.c (main): new command-line syntax: -S simply specifies
 677         which source-files user is interested in; -A requests annotated
 678         source files and -AA requests that all lines in a source file
 679         are annotated.
 680
 681         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 682
 683         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 684
 685         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 686         so s_lowpc etc. get declared.
 687
 688         * arcs.h (doarcs): created.
 689
 690         * arcs.c: reordered static functions such that they get defined
 691         before use.
 692
 693         * gprof.c (main): added options:
 694            -A: request annotation of all source lines (with -S)
 695            -m: minimum execution count (with default basic-block display)
 696            -N: force new file format (only if BSD_COMPATIBLE is defined)
 697            -S: annotate source file
 698            -t: set table length (with -S)
 699
 700         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 701         source.o time_hist.o
 702
 703         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 704
 705         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 706         on the fact being able to store a long in a double without loss of
 707         precision; this does not hold on machines with 64 bit longs and 64
 708         bit doubles.
 709
 710 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 711
 712         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 713         greater than 0.0.  Suggested by Harold Assink
 714         <carlo@sg.tn.tudelft.nl>.
 715
 716 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 717
 718         * printgprof.c (printprof): Use free, not cfree.
 719         (printgprof, printindex): Ditto.
 720
 721 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)

 884
 885 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 886
 887         * gprof.1: updated SYNOPSIS to match actual behavior.
 888
 889 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 890
 891         * gen-c-prog.awk:  New awk script, lightly changed from
 892         previously deleted make-c-prog.awk.  Converts a text file
 893         to a c function that prints that text.
 894         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 895         Inputs to gen-c-prog.awk, containing text describing
 896         gprof output.
 897         * blurbs.c:  Removed.  Use *_bl.c instead.
 898         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 899         from *_bl.m files.  Also, improve *clean rules.
 900         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 901
 902
 903 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 904
 905         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 906         output styles:  The default is similar to the old FSF gprof,
 907         while -T sets the variable bsd_style_output, which causes
 908         output matching Berkeley's gprof.  The biggest differences
 909         are that with the FSF style output, the flat profile comes
 910         before the call graph; numbers come before explanations;
 911         and there is less gratuitous white space.
 912         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 913         variable causes discarding of initial underscores when
 914         printing symbol names.  It is set unless there is a "main"
 915         symbol (without an underscore).
 916         * printfgprof.c:  New function printnameonly(), called
 917         by printname().  It handles stripping of initial '_',
 918         as well as C++ name-demangling.
 919         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 920         It is just as convenient to edit blurbs.c directly.
 921         * Makefile.in:  Removed rule for making blurbs.c.
 922         * blurbs.c:  This is now a true source file (as opposed
 923         to being generated from gprof.callg and gprof.flat).
 924         Change style to use one long string literal, instead of
 925         one literal per output line.  Add FSF-style blurb for call graph.
 926
 927 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 928
 929         * Makefile.in: always create installation directories.
 930
 931 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 932
 933         * Makefile.in: change ${MACHINE} to $(MACHINE).

 938         call.{flag,callg} files.
 939
 940         * gprof.1: now uses the standard man macros instead of the new BSD
 941         mandoc macros.
 942
 943 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 944
 945         * configure.in:  Remove host section, expand target section.
 946         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 947         * config/tmake-*:  Remove leftover crud.
 948
 949         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 950         * make-c-prog.awk:  which processes text files into C programs.
 951         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 952         to print blurbs.
 953         (printblurb):  Remove.
 954         * Makefile.in:  Infrastructure to build blurbs.
 955         * pathnames.h:  has been removed.  Gprof now has no filename
 956         dependencies in it.
 957         * gprof.c:  Lint.
 958

 966
 967 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 968
 969         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 970         help in debugging the problem (with -DDEBUG)
 971         * gprof.c: symbol values are now real values, don't add the vma
 972         anymore. (done for solaris; should verify this on other platforms)
 973         * ChangeLog: created.
