 187         name.
 188
 189         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 190         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 191         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 192
 193         * vax.c: Don't include vax.h here.

 210         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 211         on info).

 232
 233 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 234

 236         realclean.
 237
 238 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>

 254
 255 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>

 269 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 270

 274

 279 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 280

 282         to match configure script.
 283
 284 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>

 294 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>

 297
 298         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 299
 300         * All *.c: More cleanup towards GNU format.
 301
 302         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 303         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 304         that bfd_vma is only guaranteed to be at least as big as a pointer.
 305
 306         (GMON_Record_tag): added explicit enumeration values to ensure
 307         compatibility across compilers.
 308
 309         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 310         sizeof(char*).
 311
 312 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 313
 314         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 315         of constructs GNU indent couldn't handle.  Block comments not yet
 316         rewritten in GNU format.
 317
 318         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 319         binutils release.
 320
 321 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 322
 323         * symtab.c (symtab_finalize): ensure globals symbols really
 324         are favored over static ones---even if their name looks less
 325         preferable; this is important for HP-UX; for example, there
 326         is a static label Ltext_something that aliases the global
 327         symbol _start
 328
 329         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 330         output only; also, auto-scaling is now performed based on
 331         per-call, rather than total execution time, which is what it was
 332         meant to be.
 333
 334         * gprof.h (File_Format): new type.
 335
 336         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 337         sync with Cygnus version numbers though...
 338
 339         (long_options): renamed --gmon-info to --file-info, --width added,
 340         renamed --old-file-format to --file-format
 341         (main): dito; also added support to read prof files, but as
 342         mon_out_read() is not implemented, it's #ifdef'd out for now
 343
 344         (usage): update to reflect new options.
 345
 346         * gmon_io.c: replaced "old_file_format" by more general
 347         "file_format" option
 348
 349         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 350
 351         * core.c (core_sym_class): added back check for __gnu_compiled and
 352         ___gnu_compiled for the benefit of systems without
 353         bfd_find_nearest_line() support
 354
 355         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 356         with section-relative addresses
 357
 358         (core_create_function_syms): get_src_info() calls are currently
 359         enabled for OSF/1 only.  It appears to work allright for SunOS
 360         4.1.x as well, but on SPARCs it gets painfully slow with the
 361         current implementation of aout_32_find_nearest_line();
 362         unfortunately, this means that static functions will not have their
 363         filename printed in the call-graph function index; line-level
 364         profiling should still work, but requires some patience
 365
 366         * cg_print.c (cg_print_index): sanitized printing of index when
 367         using FSF-style output; in particular, output width is now controlled
 368         via option --width and the function tries hard to keep columns
 369         aligned even in the presence of (occasional) long names
 370
 371         * NOTES: a first shot at updating the documentation.
 372
 373 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 374
 375         * core.c (core_create_function_syms): fixed computation of min_vma
 376         and max_vma.
 377
 378         * *.c: removed rcsid.
 379
 380 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 381
 382         * Lots of changes from David Mosberger-Tang:
 383
 384         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 385
 386         * gprof.c (main): put parentheses around & within &&.
 387
 388         * basic_blocks.c (bb_read_rec): print warning message (once) when
 389         ignoring basic-block execution counts.
 390
 391         * source.c (source_file_lookup_name): corrected second argument to
 392         strcmp().
 393
 394         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 395         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 396
 397         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 398         supported both for old and new (versioned) gmon.out files.  Old
 399         files are identified as version 0.
 400
 401         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 402         long (instead of 4) because that is what OSF/1 v3.0 uses.
 403
 404         * core.c: minor fixes and debugging info changes.
 405
 406         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 407
 408         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 409         name of the text-section under HP-UX).
 410
 411         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 412         points one past the last sampling bin, so hist_scale should be
 413         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 414         hist_num_bins - 1".
 415
 416         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 417         hist_num_bins.
 418
 419         * configure.in: added alpha-*-*) for per-target config.
 420
 421         * alpha.c, alpha.h: created.
 422
 423         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 424
 425         * core.c (core_create_function_syms, core_create_line_syms):
 426         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 427         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 428         addr) continues to guarantee not to return 0 on any address.  It
 429         also avoids incorrectly crediting the first/last symbol in the
 430         text-space.
 431
 432         * core.c (core_create_line_syms): always create function symbols
 433         first, then merge in line symbols; this is so that if parts of the
 434         program were compiled without -g, function-level symbols are
 435         available still.
 436
 437         * utils.c (print_name_only): support for print_path added.
 438
 439         * symtab.c (cmp_addr): also use is_func flag in comparison.
 440         (symtab_finalize): return immediately when table empty; now
 441         more careful about getting rid of the right duplicate symbol.
 442
 443         * sparc.c (find_call): many fixes---this function was rather
 444         botched in binutils-2.4 already; it should work again.
 445
 446         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 447         not good to rely on get_src_info() to return distinct string
 448         pointers).
 449
 450         * search_list.c (search_list_append): added cast for xmalloc().
 451
 452         * hist.c: added explicit initialization to some of the global
 453         variables; fixed SItab (scales were off by a factor of 10).
 454
 455         * hist.h: include of bfd.h added.
 456
 457         * gprof.c, gprof.h (print_path): added.
 458
 459         * gprof.h (MAX): fixed.
 460
 461         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 462
 463         * gmon_io.c: added some casts to (long) so we can always print as %lx
 464
 465         * core.c (core_get_text_space): fixed to make it work.
 466
 467         * cg_print.c (cg_print_index): added support for print_path option.
 468
 469         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 470
 471         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 472         as some compilers complain (e.g., DEC's OSF/1 compiler)
 473
 474         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 475         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 476
 477         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 478
 479         * gprof.c: added "_mcount" to default_excluded_list.
 480         (main): if output_style==0 and there is either a histogram or a
 481         call-graph, always generate flat and call-graph, no matter what
 482         line_granularity is set to.
 483
 484         * source.c (source_file_lookup_name): if searching for sf->name
 485         fails, try again with filename obtained after stripping off any
 486         partial path from sf->name.
 487
 488         * gprof.h (SRCDEBUG): added.
 489
 490         * search_list.c (search_list_append): directories were added in wrong
 491         order.
 492
 493         * reimplemented selection mechanism from ground up; it is now possible
 494         to accurately control what gets included/excluded in each of the
 495         output styles;  a "symbol-specification" (spec) is the basic means
 496         to select a set of symbols; a spec has the syntax:
 497
 498           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 499           arc == spec/spec.
 500
 501         any of the terminal symbols can be empty, in which case they
 502         match anything (wildcards).  NAME is interpreted as a FILENAME
 503         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 504         with a digit, and as FUNCNAME otherwise.
 505
 506         For example, to get a call-graph display that ignores arcs
 507         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 508         show only arcs into bar() (no matter what the caller),
 509         you'd say "--graph=/bar"; and to get a call-graph without
 510         any arc info, you'd say "--graph=/";  similarly, to
 511         get a flat profile without mcount, you'd say "--no-flat=mcount"
 512         and to get a flat profile that shows includes all functions
 513         you'd say "--flat=""" (i.e., an empty spec)
 514
 515         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 516
 517         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 518
 519         * gmon_out.h: all headers now declared in terms of characters
 520           to avoid getting into trouble with different compilers introducing
 521           different amount of padding; the code already accessed the fields
 522           through bfd functions, so that didn't have to change.
 523
 524         * hist.c (hist_read_rec, hist_write_rec): added support for
 525           collection pc histograms measuring quantities other than time;
 526           the histogram header now includes a field that specifies the
 527           dimension of the quantity measured by the histogram bins
 528           (normally, this is "seconds", but other meaningful dimensions
 529            include such things as "I-cache misses", "instruction issue stalls"
 530            etc.); there is also a field to specify a one-character
 531           abbreviation for the dimension; in the case of time, this would
 532           be 's'; in most other cases it probably would be '1' (not a physical
 533           dimension).
 534
 535         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 536
 537         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 538           has become old_file_version; gmon_io.c now always supports old-style
 539           gmon.out files; it first tries to read gmon.out as a new version
 540           file, if that fails, it tries to read it in the old format;
 541           although not very likely, it is possible for gprof to mistake an
 542           old-style file as a new one (the first 4 bytes would have to
 543           be "gmon"---including the trailing '\0'); in that case, it is
 544           necessary to specify --old-file-version
 545
 546         * gprof.h: removed dependency on SYSV; the code now always uses
 547           strrchr(), memset(), and memcpy() and does not include either
 548           of string.h or strings.h; this should make gprof compile on
 549           any (Unix) system without configuration (per suggestion of
 550           raeburn@cygnus.com)
 551
 552         * gprof.c (usage): fixed location of --new-file-format option.
 553
 554         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 555
 556         * flat_bl.m: removed formfeed at end of file; the form-feed
 557           is now printed cg_print.c only when necessary.
 558
 559         * major rewrite of gprof---too many changes to mention all of
 560           them.  new features:
 561
 562         + -l now requests profiling at the line level (as opposed
 563           to function level); in this mode, gprof creates a "symbol"
 564           (aka name-list entry) for each line of source code, instead
 565            of one per function)
 566
 567         + support for a new gmon.out file format; the new format
 568           consists of a header with a magic and a version number,
 569           followed by a sequence of profile data; profile data
 570           can any of: (a) PC histogram, (b) call-graph arcs, or
 571           (c) basic-block execution counts; the version number makes
 572           it possible to extend gmon.out in a backwards compatible
 573           fashion
 574
 575         + support for tcov style annotated output: if the gmon.out file
 576           contains basic-block execution counts, the user can request
 577           the generation of annotated source files, much like Sun's
 578           tcov used to do
 579
 580         + long options
 581
 582         + new scheme to suppress symbols that aren't function names
 583           (e.g., avoids mistaking a goto label as a function)
 584
 585         + reorganized source code to make it more managable; as a
 586           side effect, gprof now compiles cleanly with "gcc -Wall"
 587
 588         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 589
 590         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 591         final cross-check to determine whether a static symbol should be
 592         considered as a function-name.
 593
 594         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 595
 596         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 597         stdin; this is useful if you wanna keep gmon.out files compressed;
 598         this way you can "gzcat" the compressed file into gprof.
 599
 600         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 601
 602         * basic_blocks.c (bb_annotate_source): added support for creating
 603         .tcov files when option flag_annotate_make_files is TRUE.
 604         (annotate_with_count): all counts less than the minimum count
 605         specified by -m are now annotated with hash-marks.
 606
 607         * gprof.c (main): -A is now followed by a string of option chars.
 608
 609         * basic_blocks.c (annotate_with_count): replaced b->count with
 610         cnt.
 611
 612         * source.c: flag_annotate_source replaced by source_lock_map.
 613
 614         * source.h: source_lock_map added.
 615
 616         * gprof.c (main): new command-line syntax: -S simply specifies
 617         which source-files user is interested in; -A requests annotated
 618         source files and -AA requests that all lines in a source file
 619         are annotated.
 620
 621         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 622
 623         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 624
 625         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 626         so s_lowpc etc. get declared.
 627
 628         * arcs.h (doarcs): created.
 629
 630         * arcs.c: reordered static functions such that they get defined
 631         before use.
 632
 633         * gprof.c (main): added options:
 634            -A: request annotation of all source lines (with -S)
 635            -m: minimum execution count (with default basic-block display)
 636            -N: force new file format (only if BSD_COMPATIBLE is defined)
 637            -S: annotate source file
 638            -t: set table length (with -S)
 639
 640         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 641         source.o time_hist.o
 642
 643         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 644
 645         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 646         on the fact being able to store a long in a double without loss of
 647         precision; this does not hold on machines with 64 bit longs and 64
 648         bit doubles.
 649
 650 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 651
 652         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 653         greater than 0.0.  Suggested by Harold Assink
 654         <carlo@sg.tn.tudelft.nl>.
 655
 656 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 657
 658         * printgprof.c (printprof): Use free, not cfree.
 659         (printgprof, printindex): Ditto.
 660
 661 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 662
 663         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 664         decls extern to keep native HP compiler quiet.
 665
 666 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 667
 668         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 669         __gnu_compiled, for the benefit of systems which add a leading
 670         underscore.
 671
 672 Wed Aug 24 12:49:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 673
 674         * configure.in: Change i386-*-* to i[345]86-*-*.
 675
 676 Sun Jul 10 00:35:31 1994  Ian Dall  (dall@hfrd.dsto.gov.au)
 677
 678         * ns532.c, ns532.h: New Files. ns532 support.
 679
 680         * config/mt-ns532: New File. ns532 support.
 681
 682         * gprof.c: user register int i instead of defaulting the int.
 683         Allows compilation with -Dregister= for debugging.
 684
 685         * configure.in: Add ns532 support.
 686
 687 Thu Jun 23 11:22:41 1994  Jeff Law  (law@snake.cs.utah.edu)
 688
 689         * Makefile.in (gprof): Depend on $(LIBS).
 690
 691 Fri May 27 12:24:57 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 692
 693         From binutils-2.4 release:
 694
 695         Wed May 11 22:32:00 1994  DJ Delorie (dj@ctron.com)
 696
 697         * configure.bat: [new] build makefile from makefile.in (dos)
 698         * hertz.c: allow static HERTZ (msdos needs it)
 699         * gprof.c: allow target to select "r" or "rb" for fopen
 700         * gprof.c: ignore __gnu_compiled symbols
 701         * i386.h: dfine FOPEN_RB to "rb" for dos.
 702
 703 Tue May 17 15:30:22 1994  E. Michael Smith (ems@cygnus.com)
 704
 705         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 706         so flat_bl.c would make from flat_bl.m file.
 707
 708 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 709
 710         * Makefile.in (install-info): Check for gprof.info in build dir,
 711         fall back to srcdir.  Depend on it.
 712
 713         * gprof.h (TRUE, FALSE): Always use undef before defining them.
 714
 715 Mon Apr  4 23:47:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 716
 717         * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
 718         makes (osf1) in which the value of MACHINE can not be changed.
 719         * config/*.mt: Changed appropriately.

 828
 829 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 830
 831         * gen-c-prog.awk:  New awk script, lightly changed from
 832         previously deleted make-c-prog.awk.  Converts a text file
 833         to a c function that prints that text.
 834         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 835         Inputs to gen-c-prog.awk, containing text describing
 836         gprof output.
 837         * blurbs.c:  Removed.  Use *_bl.c instead.
 838         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 839         from *_bl.m files.  Also, improve *clean rules.
 840         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 843 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 844
 845         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 846         output styles:  The default is similar to the old FSF gprof,
 847         while -T sets the variable bsd_style_output, which causes
 848         output matching Berkeley's gprof.  The biggest differences
 849         are that with the FSF style output, the flat profile comes
 850         before the call graph; numbers come before explanations;
 851         and there is less gratuitous white space.
 852         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 853         variable causes discarding of initial underscores when
 854         printing symbol names.  It is set unless there is a "main"
 855         symbol (without an underscore).
 856         * printfgprof.c:  New function printnameonly(), called
 857         by printname().  It handles stripping of initial '_',
 858         as well as C++ name-demangling.
 859         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 860         It is just as convenient to edit blurbs.c directly.
 861         * Makefile.in:  Removed rule for making blurbs.c.
 862         * blurbs.c:  This is now a true source file (as opposed
 863         to being generated from gprof.callg and gprof.flat).
 864         Change style to use one long string literal, instead of
 865         one literal per output line.  Add FSF-style blurb for call graph.
 866
 867 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 868
 869         * Makefile.in: always create installation directories.

 871 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)

 876
 877         * Makefile.in:  removed installation of the now useless
 878         call.{flag,callg} files.
 879
 880         * gprof.1: now uses the standard man macros instead of the new BSD
 881         mandoc macros.
 882
 883 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 884
 885         * configure.in:  Remove host section, expand target section.
 886         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 887         * config/tmake-*:  Remove leftover crud.
 888
 889         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 890         * make-c-prog.awk:  which processes text files into C programs.
 891         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 892         to print blurbs.
 893         (printblurb):  Remove.
 894         * Makefile.in:  Infrastructure to build blurbs.
 895         * pathnames.h:  has been removed.  Gprof now has no filename
 896         dependencies in it.
 897         * gprof.c:  Lint.

 906
 907 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 908
 909         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 910         help in debugging the problem (with -DDEBUG)
 911         * gprof.c: symbol values are now real values, don't add the vma
 912         anymore. (done for solaris; should verify this on other platforms)
 913         * ChangeLog: created.
