 367 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 368
 369         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 370         to match configure script.
 371
 372 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 373
 374         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 375           comment emitted by this script to gen-c-prog.awk.
 376
 377         * Makefile.in, configure.in: Converted to use autoconf.
 378         * configure: New file, generated with autoconf 2.3.
 379         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 380           mt-tahoe, mt-vax}: Removed.
 381
 382 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 383
 384         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 385
 386         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 387
 388         * All *.c: More cleanup towards GNU format.
 389
 390         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 391         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 392         that bfd_vma is only guaranteed to be at least as big as a pointer.
 393
 394         (GMON_Record_tag): added explicit enumeration values to ensure
 395         compatibility across compilers.
 396
 397         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 398         sizeof(char*).
 399
 400 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 401
 402         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 403         of constructs GNU indent couldn't handle.  Block comments not yet
 404         rewritten in GNU format.
 405
 406         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 407         binutils release.
 408
 409 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 410
 411         * symtab.c (symtab_finalize): ensure globals symbols really
 412         are favored over static ones---even if their name looks less
 413         preferable; this is important for HP-UX; for example, there
 414         is a static label Ltext_something that aliases the global
 415         symbol _start
 416
 417         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 418         output only; also, auto-scaling is now performed based on
 419         per-call, rather than total execution time, which is what it was
 420         meant to be.
 421
 422         * gprof.h (File_Format): new type.
 423
 424         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 425         sync with Cygnus version numbers though...
 426
 427         (long_options): renamed --gmon-info to --file-info, --width added,
 428         renamed --old-file-format to --file-format
 429         (main): dito; also added support to read prof files, but as
 430         mon_out_read() is not implemented, it's #ifdef'd out for now
 431
 432         (usage): update to reflect new options.
 433
 434         * gmon_io.c: replaced "old_file_format" by more general
 435         "file_format" option
 436
 437         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 438
 439         * core.c (core_sym_class): added back check for __gnu_compiled and
 440         ___gnu_compiled for the benefit of systems without
 441         bfd_find_nearest_line() support
 442
 443         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 444         with section-relative addresses
 445
 446         (core_create_function_syms): get_src_info() calls are currently
 447         enabled for OSF/1 only.  It appears to work allright for SunOS
 448         4.1.x as well, but on SPARCs it gets painfully slow with the
 449         current implementation of aout_32_find_nearest_line();
 450         unfortunately, this means that static functions will not have their
 451         filename printed in the call-graph function index; line-level
 452         profiling should still work, but requires some patience
 453
 454         * cg_print.c (cg_print_index): sanitised printing of index when
 455         using FSF-style output; in particular, output width is now controlled
 456         via option --width and the function tries hard to keep columns
 457         aligned even in the presence of (occasional) long names
 458
 459         * NOTES: a first shot at updating the documentation.
 460
 461 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 462
 463         * core.c (core_create_function_syms): fixed computation of min_vma
 464         and max_vma.
 465
 466         * *.c: removed rcsid.
 467
 468 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 469
 470         * Lots of changes from David Mosberger-Tang:
 471
 472         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 473
 474         * gprof.c (main): put parentheses around & within &&.
 475
 476         * basic_blocks.c (bb_read_rec): print warning message (once) when
 477         ignoring basic-block execution counts.
 478
 479         * source.c (source_file_lookup_name): corrected second argument to
 480         strcmp().
 481
 482         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 483         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 484
 485         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 486         supported both for old and new (versioned) gmon.out files.  Old
 487         files are identified as version 0.
 488
 489         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 490         long (instead of 4) because that is what OSF/1 v3.0 uses.
 491
 492         * core.c: minor fixes and debugging info changes.
 493
 494         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 495
 496         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 497         name of the text-section under HP-UX).
 498
 499         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 500         points one past the last sampling bin, so hist_scale should be
 501         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 502         hist_num_bins - 1".
 503
 504         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 505         hist_num_bins.
 506
 507         * configure.in: added alpha-*-*) for per-target config.
 508
 509         * alpha.c, alpha.h: created.
 510
 511         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 512
 513         * core.c (core_create_function_syms, core_create_line_syms):
 514         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 515         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 516         addr) continues to guarantee not to return 0 on any address.  It
 517         also avoids incorrectly crediting the first/last symbol in the
 518         text-space.
 519
 520         * core.c (core_create_line_syms): always create function symbols
 521         first, then merge in line symbols; this is so that if parts of the
 522         program were compiled without -g, function-level symbols are
 523         available still.
 524
 525         * utils.c (print_name_only): support for print_path added.
 526
 527         * symtab.c (cmp_addr): also use is_func flag in comparison.
 528         (symtab_finalize): return immediately when table empty; now
 529         more careful about getting rid of the right duplicate symbol.
 530
 531         * sparc.c (find_call): many fixes---this function was rather
 532         botched in binutils-2.4 already; it should work again.
 533
 534         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 535         not good to rely on get_src_info() to return distinct string
 536         pointers).
 537
 538         * search_list.c (search_list_append): added cast for xmalloc().
 539
 540         * hist.c: added explicit initialization to some of the global
 541         variables; fixed SItab (scales were off by a factor of 10).
 542
 543         * hist.h: include of bfd.h added.
 544
 545         * gprof.c, gprof.h (print_path): added.
 546
 547         * gprof.h (MAX): fixed.
 548
 549         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 550
 551         * gmon_io.c: added some casts to (long) so we can always print as %lx
 552
 553         * core.c (core_get_text_space): fixed to make it work.
 554
 555         * cg_print.c (cg_print_index): added support for print_path option.
 556
 557         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 558
 559         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 560         as some compilers complain (e.g., DEC's OSF/1 compiler)
 561
 562         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 563         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 564
 565         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 566
 567         * gprof.c: added "_mcount" to default_excluded_list.
 568         (main): if output_style==0 and there is either a histogram or a
 569         call-graph, always generate flat and call-graph, no matter what
 570         line_granularity is set to.
 571
 572         * source.c (source_file_lookup_name): if searching for sf->name
 573         fails, try again with filename obtained after stripping off any
 574         partial path from sf->name.
 575
 576         * gprof.h (SRCDEBUG): added.
 577
 578         * search_list.c (search_list_append): directories were added in wrong
 579         order.
 580
 581         * reimplemented selection mechanism from ground up; it is now possible
 582         to accurately control what gets included/excluded in each of the
 583         output styles;  a "symbol-specification" (spec) is the basic means
 584         to select a set of symbols; a spec has the syntax:
 585
 586           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 587           arc == spec/spec.
 588
 589         any of the terminal symbols can be empty, in which case they
 590         match anything (wildcards).  NAME is interpreted as a FILENAME
 591         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 592         with a digit, and as FUNCNAME otherwise.
 593
 594         For example, to get a call-graph display that ignores arcs
 595         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 596         show only arcs into bar() (no matter what the caller),
 597         you'd say "--graph=/bar"; and to get a call-graph without
 598         any arc info, you'd say "--graph=/";  similarly, to
 599         get a flat profile without mcount, you'd say "--no-flat=mcount"
 600         and to get a flat profile that shows includes all functions
 601         you'd say "--flat=""" (i.e., an empty spec)
 602
 603         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 604
 605         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 606
 607         * gmon_out.h: all headers now declared in terms of characters
 608           to avoid getting into trouble with different compilers introducing
 609           different amount of padding; the code already accessed the fields
 610           through bfd functions, so that didn't have to change.
 611
 612         * hist.c (hist_read_rec, hist_write_rec): added support for
 613           collection pc histograms measuring quantities other than time;
 614           the histogram header now includes a field that specifies the
 615           dimension of the quantity measured by the histogram bins
 616           (normally, this is "seconds", but other meaningful dimensions
 617            include such things as "I-cache misses", "instruction issue stalls"
 618            etc.); there is also a field to specify a one-character
 619           abbreviation for the dimension; in the case of time, this would
 620           be 's'; in most other cases it probably would be '1' (not a physical
 621           dimension).
 622
 623         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 624
 625         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 626           has become old_file_version; gmon_io.c now always supports old-style
 627           gmon.out files; it first tries to read gmon.out as a new version
 628           file, if that fails, it tries to read it in the old format;
 629           although not very likely, it is possible for gprof to mistake an
 630           old-style file as a new one (the first 4 bytes would have to
 631           be "gmon"---including the trailing '\0'); in that case, it is
 632           necessary to specify --old-file-version
 633
 634         * gprof.h: removed dependency on SYSV; the code now always uses
 635           strrchr(), memset(), and memcpy() and does not include either
 636           of string.h or strings.h; this should make gprof compile on
 637           any (Unix) system without configuration (per suggestion of
 638           raeburn@cygnus.com)
 639
 640         * gprof.c (usage): fixed location of --new-file-format option.
 641
 642         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 643
 644         * flat_bl.m: removed formfeed at end of file; the form-feed
 645           is now printed cg_print.c only when necessary.
 646
 647         * major rewrite of gprof---too many changes to mention all of
 648           them.  new features:
 649
 650         + -l now requests profiling at the line level (as opposed
 651           to function level); in this mode, gprof creates a "symbol"
 652           (aka name-list entry) for each line of source code, instead
 653            of one per function)
 654
 655         + support for a new gmon.out file format; the new format
 656           consists of a header with a magic and a version number,
 657           followed by a sequence of profile data; profile data
 658           can any of: (a) PC histogram, (b) call-graph arcs, or
 659           (c) basic-block execution counts; the version number makes
 660           it possible to extend gmon.out in a backwards compatible
 661           fashion
 662
 663         + support for tcov style annotated output: if the gmon.out file
 664           contains basic-block execution counts, the user can request
 665           the generation of annotated source files, much like Sun's
 666           tcov used to do
 667
 668         + long options
 669
 670         + new scheme to suppress symbols that aren't function names
 671           (e.g., avoids mistaking a goto label as a function)
 672
 673         + reorganized source code to make it more managable; as a
 674           side effect, gprof now compiles cleanly with "gcc -Wall"
 675
 676         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 677
 678         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 679         final cross-check to determine whether a static symbol should be
 680         considered as a function-name.
 681
 682         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 683
 684         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 685         stdin; this is useful if you wanna keep gmon.out files compressed;
 686         this way you can "gzcat" the compressed file into gprof.
 687
 688         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 689
 690         * basic_blocks.c (bb_annotate_source): added support for creating
 691         .tcov files when option flag_annotate_make_files is TRUE.
 692         (annotate_with_count): all counts less than the minimum count
 693         specified by -m are now annotated with hash-marks.
 694
 695         * gprof.c (main): -A is now followed by a string of option chars.
 696
 697         * basic_blocks.c (annotate_with_count): replaced b->count with
 698         cnt.
 699
 700         * source.c: flag_annotate_source replaced by source_lock_map.
 701
 702         * source.h: source_lock_map added.
 703
 704         * gprof.c (main): new command-line syntax: -S simply specifies
 705         which source-files user is interested in; -A requests annotated
 706         source files and -AA requests that all lines in a source file
 707         are annotated.
 708
 709         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 710
 711         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 712
 713         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 714         so s_lowpc etc. get declared.
 715
 716         * arcs.h (doarcs): created.
 717
 718         * arcs.c: reordered static functions such that they get defined
 719         before use.
 720
 721         * gprof.c (main): added options:
 722            -A: request annotation of all source lines (with -S)
 723            -m: minimum execution count (with default basic-block display)

 732
 733         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 734         on the fact being able to store a long in a double without loss of
 735         precision; this does not hold on machines with 64 bit longs and 64
 736         bit doubles.

 912
 913 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 914
 915         * gprof.1: updated SYNOPSIS to match actual behavior.
 916
 917 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 918
 919         * gen-c-prog.awk:  New awk script, lightly changed from
 920         previously deleted make-c-prog.awk.  Converts a text file
 921         to a c function that prints that text.
 922         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 923         Inputs to gen-c-prog.awk, containing text describing
 924         gprof output.
 925         * blurbs.c:  Removed.  Use *_bl.c instead.
 926         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 927         from *_bl.m files.  Also, improve *clean rules.
 928         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 929
 930
 931 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 932
 933         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 934         output styles:  The default is similar to the old FSF gprof,
 935         while -T sets the variable bsd_style_output, which causes
 936         output matching Berkeley's gprof.  The biggest differences
 937         are that with the FSF style output, the flat profile comes
 938         before the call graph; numbers come before explanations;
 939         and there is less gratuitous white space.
 940         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 941         variable causes discarding of initial underscores when
 942         printing symbol names.  It is set unless there is a "main"
 943         symbol (without an underscore).
 944         * printfgprof.c:  New function printnameonly(), called
 945         by printname().  It handles stripping of initial '_',
 946         as well as C++ name-demangling.
 947         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 948         It is just as convenient to edit blurbs.c directly.
 949         * Makefile.in:  Removed rule for making blurbs.c.
 950         * blurbs.c:  This is now a true source file (as opposed
 951         to being generated from gprof.callg and gprof.flat).
 952         Change style to use one long string literal, instead of
 953         one literal per output line.  Add FSF-style blurb for call graph.
 954
 955 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 956
 957         * Makefile.in: always create installation directories.

 966         call.{flag,callg} files.
 967
 968         * gprof.1: now uses the standard man macros instead of the new BSD
 969         mandoc macros.
 970
 971 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 972
 973         * configure.in:  Remove host section, expand target section.
 974         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 975         * config/tmake-*:  Remove leftover crud.
 976
 977         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 978         * make-c-prog.awk:  which processes text files into C programs.
 979         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 980         to print blurbs.
 981         (printblurb):  Remove.
 982         * Makefile.in:  Infrastructure to build blurbs.
 983         * pathnames.h:  has been removed.  Gprof now has no filename
 984         dependencies in it.
 985         * gprof.c:  Lint.
 986

 994
 995 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 996
 997         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 998         help in debugging the problem (with -DDEBUG)
 999         * gprof.c: symbol values are now real values, don't add the vma
1000         anymore. (done for solaris; should verify this on other platforms)
1001         * ChangeLog: created.
