 367           (SHELL): New definition.
 368
 369 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 370
 371         * Makefile.in (install): Depend on "all".
 372
 373 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 374
 375         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 376         to match configure script.
 377
 378 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 379
 380         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 381           comment emitted by this script to gen-c-prog.awk.
 382
 383         * Makefile.in, configure.in: Converted to use autoconf.
 384         * configure: New file, generated with autoconf 2.3.
 385         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 386           mt-tahoe, mt-vax}: Removed.
 387
 388 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 389
 390         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 391
 392         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 393
 394         * All *.c: More cleanup towards GNU format.
 395
 396         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 397         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 398         that bfd_vma is only guaranteed to be at least as big as a pointer.
 399
 400         (GMON_Record_tag): added explicit enumeration values to ensure
 401         compatibility across compilers.
 402
 403         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 404         sizeof(char*).
 405
 406 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 407
 408         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 409         of constructs GNU indent couldn't handle.  Block comments not yet
 410         rewritten in GNU format.
 411
 412         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 413         binutils release.
 414
 415 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 416
 417         * symtab.c (symtab_finalize): ensure globals symbols really
 418         are favored over static ones---even if their name looks less
 419         preferable; this is important for HP-UX; for example, there
 420         is a static label Ltext_something that aliases the global
 421         symbol _start
 422
 423         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 424         output only; also, auto-scaling is now performed based on
 425         per-call, rather than total execution time, which is what it was
 426         meant to be.
 427
 428         * gprof.h (File_Format): new type.
 429
 430         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 431         sync with Cygnus version numbers though...
 432
 433         (long_options): renamed --gmon-info to --file-info, --width added,
 434         renamed --old-file-format to --file-format
 435         (main): dito; also added support to read prof files, but as
 436         mon_out_read() is not implemented, it's #ifdef'd out for now
 437
 438         (usage): update to reflect new options.
 439
 440         * gmon_io.c: replaced "old_file_format" by more general
 441         "file_format" option
 442
 443         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 444
 445         * core.c (core_sym_class): added back check for __gnu_compiled and
 446         ___gnu_compiled for the benefit of systems without
 447         bfd_find_nearest_line() support
 448
 449         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 450         with section-relative addresses
 451
 452         (core_create_function_syms): get_src_info() calls are currently
 453         enabled for OSF/1 only.  It appears to work allright for SunOS
 454         4.1.x as well, but on SPARCs it gets painfully slow with the
 455         current implementation of aout_32_find_nearest_line();
 456         unfortunately, this means that static functions will not have their
 457         filename printed in the call-graph function index; line-level
 458         profiling should still work, but requires some patience
 459
 460         * cg_print.c (cg_print_index): sanitised printing of index when
 461         using FSF-style output; in particular, output width is now controlled
 462         via option --width and the function tries hard to keep columns
 463         aligned even in the presence of (occasional) long names
 464
 465         * NOTES: a first shot at updating the documentation.
 466
 467 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 468
 469         * core.c (core_create_function_syms): fixed computation of min_vma
 470         and max_vma.
 471
 472         * *.c: removed rcsid.
 473
 474 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 475
 476         * Lots of changes from David Mosberger-Tang:
 477
 478         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 479
 480         * gprof.c (main): put parentheses around & within &&.
 481
 482         * basic_blocks.c (bb_read_rec): print warning message (once) when
 483         ignoring basic-block execution counts.
 484
 485         * source.c (source_file_lookup_name): corrected second argument to
 486         strcmp().
 487
 488         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 489         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 490
 491         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 492         supported both for old and new (versioned) gmon.out files.  Old
 493         files are identified as version 0.
 494
 495         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 496         long (instead of 4) because that is what OSF/1 v3.0 uses.
 497
 498         * core.c: minor fixes and debugging info changes.
 499
 500         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 501
 502         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 503         name of the text-section under HP-UX).
 504
 505         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 506         points one past the last sampling bin, so hist_scale should be
 507         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 508         hist_num_bins - 1".
 509
 510         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 511         hist_num_bins.
 512
 513         * configure.in: added alpha-*-*) for per-target config.
 514
 515         * alpha.c, alpha.h: created.
 516
 517         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 518
 519         * core.c (core_create_function_syms, core_create_line_syms):
 520         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 521         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 522         addr) continues to guarantee not to return 0 on any address.  It
 523         also avoids incorrectly crediting the first/last symbol in the
 524         text-space.
 525
 526         * core.c (core_create_line_syms): always create function symbols
 527         first, then merge in line symbols; this is so that if parts of the
 528         program were compiled without -g, function-level symbols are
 529         available still.
 530
 531         * utils.c (print_name_only): support for print_path added.
 532
 533         * symtab.c (cmp_addr): also use is_func flag in comparison.
 534         (symtab_finalize): return immediately when table empty; now
 535         more careful about getting rid of the right duplicate symbol.
 536
 537         * sparc.c (find_call): many fixes---this function was rather
 538         botched in binutils-2.4 already; it should work again.
 539
 540         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 541         not good to rely on get_src_info() to return distinct string
 542         pointers).
 543
 544         * search_list.c (search_list_append): added cast for xmalloc().
 545
 546         * hist.c: added explicit initialization to some of the global
 547         variables; fixed SItab (scales were off by a factor of 10).
 548
 549         * hist.h: include of bfd.h added.
 550
 551         * gprof.c, gprof.h (print_path): added.
 552
 553         * gprof.h (MAX): fixed.
 554
 555         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 556
 557         * gmon_io.c: added some casts to (long) so we can always print as %lx
 558
 559         * core.c (core_get_text_space): fixed to make it work.
 560
 561         * cg_print.c (cg_print_index): added support for print_path option.
 562
 563         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 564
 565         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 566         as some compilers complain (e.g., DEC's OSF/1 compiler)
 567
 568         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 569         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 570
 571         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 572
 573         * gprof.c: added "_mcount" to default_excluded_list.
 574         (main): if output_style==0 and there is either a histogram or a
 575         call-graph, always generate flat and call-graph, no matter what
 576         line_granularity is set to.
 577
 578         * source.c (source_file_lookup_name): if searching for sf->name
 579         fails, try again with filename obtained after stripping off any
 580         partial path from sf->name.
 581
 582         * gprof.h (SRCDEBUG): added.
 583
 584         * search_list.c (search_list_append): directories were added in wrong
 585         order.
 586
 587         * reimplemented selection mechanism from ground up; it is now possible
 588         to accurately control what gets included/excluded in each of the
 589         output styles;  a "symbol-specification" (spec) is the basic means
 590         to select a set of symbols; a spec has the syntax:
 591
 592           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 593           arc == spec/spec.
 594
 595         any of the terminal symbols can be empty, in which case they
 596         match anything (wildcards).  NAME is interpreted as a FILENAME
 597         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 598         with a digit, and as FUNCNAME otherwise.
 599
 600         For example, to get a call-graph display that ignores arcs
 601         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 602         show only arcs into bar() (no matter what the caller),
 603         you'd say "--graph=/bar"; and to get a call-graph without
 604         any arc info, you'd say "--graph=/";  similarly, to
 605         get a flat profile without mcount, you'd say "--no-flat=mcount"
 606         and to get a flat profile that shows includes all functions
 607         you'd say "--flat=""" (i.e., an empty spec)
 608
 609         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 610
 611         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 612
 613         * gmon_out.h: all headers now declared in terms of characters
 614           to avoid getting into trouble with different compilers introducing
 615           different amount of padding; the code already accessed the fields
 616           through bfd functions, so that didn't have to change.
 617
 618         * hist.c (hist_read_rec, hist_write_rec): added support for
 619           collection pc histograms measuring quantities other than time;
 620           the histogram header now includes a field that specifies the
 621           dimension of the quantity measured by the histogram bins
 622           (normally, this is "seconds", but other meaningful dimensions
 623            include such things as "I-cache misses", "instruction issue stalls"
 624            etc.); there is also a field to specify a one-character
 625           abbreviation for the dimension; in the case of time, this would
 626           be 's'; in most other cases it probably would be '1' (not a physical
 627           dimension).
 628
 629         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 630
 631         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 632           has become old_file_version; gmon_io.c now always supports old-style
 633           gmon.out files; it first tries to read gmon.out as a new version
 634           file, if that fails, it tries to read it in the old format;
 635           although not very likely, it is possible for gprof to mistake an
 636           old-style file as a new one (the first 4 bytes would have to
 637           be "gmon"---including the trailing '\0'); in that case, it is
 638           necessary to specify --old-file-version
 639
 640         * gprof.h: removed dependency on SYSV; the code now always uses
 641           strrchr(), memset(), and memcpy() and does not include either
 642           of string.h or strings.h; this should make gprof compile on
 643           any (Unix) system without configuration (per suggestion of
 644           raeburn@cygnus.com)
 645
 646         * gprof.c (usage): fixed location of --new-file-format option.
 647
 648         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 649
 650         * flat_bl.m: removed formfeed at end of file; the form-feed
 651           is now printed cg_print.c only when necessary.
 652
 653         * major rewrite of gprof---too many changes to mention all of
 654           them.  new features:
 655
 656         + -l now requests profiling at the line level (as opposed
 657           to function level); in this mode, gprof creates a "symbol"
 658           (aka name-list entry) for each line of source code, instead
 659            of one per function)
 660
 661         + support for a new gmon.out file format; the new format
 662           consists of a header with a magic and a version number,
 663           followed by a sequence of profile data; profile data
 664           can any of: (a) PC histogram, (b) call-graph arcs, or
 665           (c) basic-block execution counts; the version number makes
 666           it possible to extend gmon.out in a backwards compatible
 667           fashion
 668
 669         + support for tcov style annotated output: if the gmon.out file
 670           contains basic-block execution counts, the user can request
 671           the generation of annotated source files, much like Sun's
 672           tcov used to do
 673
 674         + long options
 675
 676         + new scheme to suppress symbols that aren't function names
 677           (e.g., avoids mistaking a goto label as a function)
 678
 679         + reorganized source code to make it more managable; as a
 680           side effect, gprof now compiles cleanly with "gcc -Wall"
 681
 682         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 683
 684         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 685         final cross-check to determine whether a static symbol should be
 686         considered as a function-name.
 687
 688         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 689
 690         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 691         stdin; this is useful if you wanna keep gmon.out files compressed;
 692         this way you can "gzcat" the compressed file into gprof.
 693
 694         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 695
 696         * basic_blocks.c (bb_annotate_source): added support for creating
 697         .tcov files when option flag_annotate_make_files is TRUE.
 698         (annotate_with_count): all counts less than the minimum count
 699         specified by -m are now annotated with hash-marks.
 700
 701         * gprof.c (main): -A is now followed by a string of option chars.
 702
 703         * basic_blocks.c (annotate_with_count): replaced b->count with
 704         cnt.
 705
 706         * source.c: flag_annotate_source replaced by source_lock_map.
 707
 708         * source.h: source_lock_map added.
 709
 710         * gprof.c (main): new command-line syntax: -S simply specifies
 711         which source-files user is interested in; -A requests annotated
 712         source files and -AA requests that all lines in a source file
 713         are annotated.
 714
 715         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 716
 717         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 718
 719         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 720         so s_lowpc etc. get declared.
 721
 722         * arcs.h (doarcs): created.
 723
 724         * arcs.c: reordered static functions such that they get defined
 725         before use.
 726
 727         * gprof.c (main): added options:
 728            -A: request annotation of all source lines (with -S)
 729            -m: minimum execution count (with default basic-block display)

 738
 739         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 740         on the fact being able to store a long in a double without loss of
 741         precision; this does not hold on machines with 64 bit longs and 64
 742         bit doubles.

 918
 919 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 920
 921         * gprof.1: updated SYNOPSIS to match actual behavior.
 922
 923 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 924
 925         * gen-c-prog.awk:  New awk script, lightly changed from
 926         previously deleted make-c-prog.awk.  Converts a text file
 927         to a c function that prints that text.
 928         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 929         Inputs to gen-c-prog.awk, containing text describing
 930         gprof output.
 931         * blurbs.c:  Removed.  Use *_bl.c instead.
 932         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 933         from *_bl.m files.  Also, improve *clean rules.
 934         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 935
 936
 937 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 938
 939         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 940         output styles:  The default is similar to the old FSF gprof,
 941         while -T sets the variable bsd_style_output, which causes
 942         output matching Berkeley's gprof.  The biggest differences
 943         are that with the FSF style output, the flat profile comes
 944         before the call graph; numbers come before explanations;
 945         and there is less gratuitous white space.
 946         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 947         variable causes discarding of initial underscores when
 948         printing symbol names.  It is set unless there is a "main"
 949         symbol (without an underscore).
 950         * printfgprof.c:  New function printnameonly(), called
 951         by printname().  It handles stripping of initial '_',
 952         as well as C++ name-demangling.
 953         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 954         It is just as convenient to edit blurbs.c directly.
 955         * Makefile.in:  Removed rule for making blurbs.c.
 956         * blurbs.c:  This is now a true source file (as opposed
 957         to being generated from gprof.callg and gprof.flat).
 958         Change style to use one long string literal, instead of
 959         one literal per output line.  Add FSF-style blurb for call graph.
 960
 961 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 962
 963         * Makefile.in: always create installation directories.

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

1001 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
1002
1003         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
1004         help in debugging the problem (with -DDEBUG)
1005         * gprof.c: symbol values are now real values, don't add the vma
1006         anymore. (done for solaris; should verify this on other platforms)
1007         * ChangeLog: created.
