  10
  11         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
  12         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
  13         on info).
  14

  51
  52 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
  53
  54         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
  55         that we're using autoconf.
  56
  57 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
  58
  59         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
  60         to proper type of "unsigned int *".
  61
  62 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  63
  64         * configure.in: Use changequote around use of [].
  65
  66 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  67
  68         * Makefile.in (distclean, realclean): Remove config.cache and
  69           config.log.
  70
  71 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  72
  73         * Makefile.in (Makefile): Added config.status to dependency list.
  74           (config.status): New target.
  75           (SHELL): New definition.
  76
  77 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  78
  79         * Makefile.in (install): Depend on "all".
  80
  81 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  82
  83         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
  84         to match configure script.
  85
  86 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  87
  88         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
  89           comment emitted by this script to gen-c-prog.awk.
  90
  91         * Makefile.in, configure.in: Converted to use autoconf.
  92         * configure: New file, generated with autoconf 2.3.
  93         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
  94           mt-tahoe, mt-vax}: Removed.
  95
  96 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  97
  98         * __bb_exit_func.c: New file, from David Mosberger-Tang.
  99
 100         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 101
 102         * All *.c: More cleanup towards GNU format.
 103
 104         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 105         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 106         that bfd_vma is only guaranteed to be at least as big as a pointer.
 107
 108         (GMON_Record_tag): added explicit enumeration values to ensure
 109         compatibility across compilers.
 110
 111         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 112         sizeof(char*).
 113
 114 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 115
 116         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 117         of constructs GNU indent couldn't handle.  Block comments not yet
 118         rewritten in GNU format.
 119
 120         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 121         binutils release.
 122
 123 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 124
 125         * symtab.c (symtab_finalize): ensure globals symbols really
 126         are favored over static ones---even if their name looks less
 127         preferable; this is important for HP-UX; for example, there
 128         is a static label Ltext_something that aliases the global
 129         symbol _start
 130
 131         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 132         output only; also, auto-scaling is now performed based on
 133         per-call, rather than total execution time, which is what it was
 134         meant to be.
 135
 136         * gprof.h (File_Format): new type.
 137
 138         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 139         sync with Cygnus version numbers though...
 140
 141         (long_options): renamed --gmon-info to --file-info, --width added,
 142         renamed --old-file-format to --file-format
 143         (main): dito; also added support to read prof files, but as
 144         mon_out_read() is not implemented, it's #ifdef'd out for now
 145
 146         (usage): update to reflect new options.
 147
 148         * gmon_io.c: replaced "old_file_format" by more general
 149         "file_format" option
 150
 151         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 152
 153         * core.c (core_sym_class): added back check for __gnu_compiled and
 154         ___gnu_compiled for the benefit of systems without
 155         bfd_find_nearest_line() support
 156
 157         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 158         with section-relative addresses
 159
 160         (core_create_function_syms): get_src_info() calls are currently
 161         enabled for OSF/1 only.  It appears to work allright for SunOS
 162         4.1.x as well, but on SPARCs it gets painfully slow with the
 163         current implementation of aout_32_find_nearest_line();
 164         unfortunately, this means that static functions will not have their
 165         filename printed in the call-graph function index; line-level
 166         profiling should still work, but requires some patience
 167
 168         * cg_print.c (cg_print_index): sanitized printing of index when
 169         using FSF-style output; in particular, output width is now controlled
 170         via option --width and the function tries hard to keep columns
 171         aligned even in the presence of (occasional) long names
 172
 173         * NOTES: a first shot at updating the documentation.
 174
 175 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 176
 177         * core.c (core_create_function_syms): fixed computation of min_vma
 178         and max_vma.
 179
 180         * *.c: removed rcsid.
 181
 182 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 183
 184         * Lots of changes from David Mosberger-Tang:
 185
 186         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 187
 188         * gprof.c (main): put parentheses around & within &&.
 189
 190         * basic_blocks.c (bb_read_rec): print warning message (once) when
 191         ignoring basic-block execution counts.
 192
 193         * source.c (source_file_lookup_name): corrected second argument to
 194         strcmp().
 195
 196         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 197         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 198
 199         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 200         supported both for old and new (versioned) gmon.out files.  Old
 201         files are identified as version 0.
 202
 203         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 204         long (instead of 4) because that is what OSF/1 v3.0 uses.
 205
 206         * core.c: minor fixes and debugging info changes.
 207
 208         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 209
 210         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 211         name of the text-section under HP-UX).
 212
 213         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 214         points one past the last sampling bin, so hist_scale should be
 215         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 216         hist_num_bins - 1".
 217
 218         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 219         hist_num_bins.
 220
 221         * configure.in: added alpha-*-*) for per-target config.
 222
 223         * alpha.c, alpha.h: created.
 224
 225         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 226
 227         * core.c (core_create_function_syms, core_create_line_syms):
 228         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 229         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 230         addr) continues to guarantee not to return 0 on any address.  It
 231         also avoids incorrectly crediting the first/last symbol in the
 232         text-space.
 233
 234         * core.c (core_create_line_syms): always create function symbols
 235         first, then merge in line symbols; this is so that if parts of the
 236         program were compiled without -g, function-level symbols are
 237         available still.
 238
 239         * utils.c (print_name_only): support for print_path added.
 240
 241         * symtab.c (cmp_addr): also use is_func flag in comparison.
 242         (symtab_finalize): return immediately when table empty; now
 243         more careful about getting rid of the right duplicate symbol.
 244
 245         * sparc.c (find_call): many fixes---this function was rather
 246         botched in binutils-2.4 already; it should work again.
 247
 248         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 249         not good to rely on get_src_info() to return distinct string
 250         pointers).
 251
 252         * search_list.c (search_list_append): added cast for xmalloc().
 253
 254         * hist.c: added explicit initialization to some of the global
 255         variables; fixed SItab (scales were off by a factor of 10).
 256
 257         * hist.h: include of bfd.h added.
 258
 259         * gprof.c, gprof.h (print_path): added.
 260
 261         * gprof.h (MAX): fixed.
 262
 263         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 264
 265         * gmon_io.c: added some casts to (long) so we can always print as %lx
 266
 267         * core.c (core_get_text_space): fixed to make it work.
 268
 269         * cg_print.c (cg_print_index): added support for print_path option.
 270
 271         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 272
 273         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 274         as some compilers complain (e.g., DEC's OSF/1 compiler)
 275
 276         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 277         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 278
 279         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 280
 281         * gprof.c: added "_mcount" to default_excluded_list.
 282         (main): if output_style==0 and there is either a histogram or a
 283         call-graph, always generate flat and call-graph, no matter what
 284         line_granularity is set to.
 285
 286         * source.c (source_file_lookup_name): if searching for sf->name
 287         fails, try again with filename obtained after stripping off any
 288         partial path from sf->name.
 289
 290         * gprof.h (SRCDEBUG): added.
 291
 292         * search_list.c (search_list_append): directories were added in wrong
 293         order.
 294
 295         * reimplemented selection mechanism from ground up; it is now possible
 296         to accurately control what gets included/excluded in each of the
 297         output styles;  a "symbol-specification" (spec) is the basic means
 298         to select a set of symbols; a spec has the syntax:
 299
 300           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 301           arc == spec/spec.
 302
 303         any of the terminal symbols can be empty, in which case they
 304         match anything (wildcards).  NAME is interpreted as a FILENAME
 305         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 306         with a digit, and as FUNCNAME otherwise.
 307
 308         For example, to get a call-graph display that ignores arcs
 309         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 310         show only arcs into bar() (no matter what the caller),
 311         you'd say "--graph=/bar"; and to get a call-graph without
 312         any arc info, you'd say "--graph=/";  similarly, to
 313         get a flat profile without mcount, you'd say "--no-flat=mcount"
 314         and to get a flat profile that shows includes all functions
 315         you'd say "--flat=""" (i.e., an empty spec)
 316
 317         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 318
 319         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 320
 321         * gmon_out.h: all headers now declared in terms of characters
 322           to avoid getting into trouble with different compilers introducing
 323           different amount of padding; the code already accessed the fields
 324           through bfd functions, so that didn't have to change.
 325
 326         * hist.c (hist_read_rec, hist_write_rec): added support for
 327           collection pc histograms measuring quantities other than time;
 328           the histogram header now includes a field that specifies the
 329           dimension of the quantity measured by the histogram bins
 330           (normally, this is "seconds", but other meaningful dimensions
 331            include such things as "I-cache misses", "instruction issue stalls"
 332            etc.); there is also a field to specify a one-character
 333           abbreviation for the dimension; in the case of time, this would
 334           be 's'; in most other cases it probably would be '1' (not a physical
 335           dimension).
 336
 337         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 338
 339         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 340           has become old_file_version; gmon_io.c now always supports old-style
 341           gmon.out files; it first tries to read gmon.out as a new version
 342           file, if that fails, it tries to read it in the old format;
 343           although not very likely, it is possible for gprof to mistake an
 344           old-style file as a new one (the first 4 bytes would have to
 345           be "gmon"---including the trailing '\0'); in that case, it is
 346           necessary to specify --old-file-version
 347
 348         * gprof.h: removed dependency on SYSV; the code now always uses
 349           strrchr(), memset(), and memcpy() and does not include either
 350           of string.h or strings.h; this should make gprof compile on
 351           any (Unix) system without configuration (per suggestion of
 352           raeburn@cygnus.com)
 353
 354         * gprof.c (usage): fixed location of --new-file-format option.
 355
 356         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 357
 358         * flat_bl.m: removed formfeed at end of file; the form-feed
 359           is now printed cg_print.c only when necessary.
 360
 361         * major rewrite of gprof---too many changes to mention all of
 362           them.  new features:
 363
 364         + -l now requests profiling at the line level (as opposed
 365           to function level); in this mode, gprof creates a "symbol"
 366           (aka name-list entry) for each line of source code, instead
 367            of one per function)
 368
 369         + support for a new gmon.out file format; the new format
 370           consists of a header with a magic and a version number,
 371           followed by a sequence of profile data; profile data
 372           can any of: (a) PC histogram, (b) call-graph arcs, or
 373           (c) basic-block execution counts; the version number makes
 374           it possible to extend gmon.out in a backwards compatible
 375           fashion
 376
 377         + support for tcov style annotated output: if the gmon.out file
 378           contains basic-block execution counts, the user can request
 379           the generation of annotated source files, much like Sun's
 380           tcov used to do
 381
 382         + long options
 383
 384         + new scheme to suppress symbols that aren't function names
 385           (e.g., avoids mistaking a goto label as a function)
 386
 387         + reorganized source code to make it more managable; as a
 388           side effect, gprof now compiles cleanly with "gcc -Wall"

 391
 392         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 393         final cross-check to determine whether a static symbol should be
 394         considered as a function-name.
 395
 396         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 397
 398         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 399         stdin; this is useful if you wanna keep gmon.out files compressed;
 400         this way you can "gzcat" the compressed file into gprof.
 401
 402         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 403
 404         * basic_blocks.c (bb_annotate_source): added support for creating
 405         .tcov files when option flag_annotate_make_files is TRUE.
 406         (annotate_with_count): all counts less than the minimum count
 407         specified by -m are now annotated with hash-marks.
 408
 409         * gprof.c (main): -A is now followed by a string of option chars.
 410
 411         * basic_blocks.c (annotate_with_count): replaced b->count with
 412         cnt.
 413
 414         * source.c: flag_annotate_source replaced by source_lock_map.
 415
 416         * source.h: source_lock_map added.
 417
 418         * gprof.c (main): new command-line syntax: -S simply specifies
 419         which source-files user is interested in; -A requests annotated
 420         source files and -AA requests that all lines in a source file
 421         are annotated.
 422
 423         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 424
 425         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 426
 427         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 428         so s_lowpc etc. get declared.
 429
 430         * arcs.h (doarcs): created.
 431
 432         * arcs.c: reordered static functions such that they get defined
 433         before use.
 434
 435         * gprof.c (main): added options:
 436            -A: request annotation of all source lines (with -S)
 437            -m: minimum execution count (with default basic-block display)
 438            -N: force new file format (only if BSD_COMPATIBLE is defined)
 439            -S: annotate source file
 440            -t: set table length (with -S)
 441
 442         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 443         source.o time_hist.o
 444
 445         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 446
 447         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 448         on the fact being able to store a long in a double without loss of
 449         precision; this does not hold on machines with 64 bit longs and 64
 450         bit doubles.

 452 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>

 460         * printgprof.c (printprof): Use free, not cfree.
 461         (printgprof, printindex): Ditto.

 463 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 464
 465         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 466         decls extern to keep native HP compiler quiet.

 468 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 469
 470         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as

 486
 487         * configure.in: Add ns532 support.

 507         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 508         so flat_bl.c would make from flat_bl.m file.
 509
 510 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 511

 626
 627 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 628
 629         * gprof.1: updated SYNOPSIS to match actual behavior.
 630
 631 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 632
 633         * gen-c-prog.awk:  New awk script, lightly changed from
 634         previously deleted make-c-prog.awk.  Converts a text file
 635         to a c function that prints that text.
 636         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 637         Inputs to gen-c-prog.awk, containing text describing
 638         gprof output.
 639         * blurbs.c:  Removed.  Use *_bl.c instead.
 640         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 641         from *_bl.m files.  Also, improve *clean rules.
 642         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 643
 644
 645 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 646
 647         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 648         output styles:  The default is similar to the old FSF gprof,
 649         while -T sets the variable bsd_style_output, which causes
 650         output matching Berkeley's gprof.  The biggest differences
 651         are that with the FSF style output, the flat profile comes
 652         before the call graph; numbers come before explanations;
 653         and there is less gratuitous white space.
 654         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 655         variable causes discarding of initial underscores when
 656         printing symbol names.  It is set unless there is a "main"
 657         symbol (without an underscore).
 658         * printfgprof.c:  New function printnameonly(), called
 659         by printname().  It handles stripping of initial '_',
 660         as well as C++ name-demangling.
 661         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 662         It is just as convenient to edit blurbs.c directly.
 663         * Makefile.in:  Removed rule for making blurbs.c.
 664         * blurbs.c:  This is now a true source file (as opposed
 665         to being generated from gprof.callg and gprof.flat).
 666         Change style to use one long string literal, instead of
 667         one literal per output line.  Add FSF-style blurb for call graph.
 668
 669 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 670
 671         * Makefile.in: always create installation directories.

 678
 679         * Makefile.in:  removed installation of the now useless
 680         call.{flag,callg} files.
 681
 682         * gprof.1: now uses the standard man macros instead of the new BSD
 683         mandoc macros.
 684
 685 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 686
 687         * configure.in:  Remove host section, expand target section.
 688         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 689         * config/tmake-*:  Remove leftover crud.
 690
 691         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 692         * make-c-prog.awk:  which processes text files into C programs.
 693         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 694         to print blurbs.
 695         (printblurb):  Remove.
 696         * Makefile.in:  Infrastructure to build blurbs.
 697         * pathnames.h:  has been removed.  Gprof now has no filename
 698         dependencies in it.
 699         * gprof.c:  Lint.

 709 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 710
 711         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 712         help in debugging the problem (with -DDEBUG)
 713         * gprof.c: symbol values are now real values, don't add the vma
 714         anymore. (done for solaris; should verify this on other platforms)
 715         * ChangeLog: created.
