  28 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
  29
  30         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
  31         that we're using autoconf.
  32
  33 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
  34
  35         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
  36         to proper type of "unsigned int *".
  37
  38 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  39
  40         * configure.in: Use changequote around use of [].
  41
  42 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  43
  44         * Makefile.in (distclean, realclean): Remove config.cache and

  52
  53 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  54
  55         * Makefile.in (install): Depend on "all".
  56
  57 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  58
  59         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
  60         to match configure script.
  61
  62 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  63
  64         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
  65           comment emitted by this script to gen-c-prog.awk.
  66
  67         * Makefile.in, configure.in: Converted to use autoconf.
  68         * configure: New file, generated with autoconf 2.3.
  69         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
  70           mt-tahoe, mt-vax}: Removed.
  71
  72 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  73
  74         * __bb_exit_func.c: New file, from David Mosberger-Tang.
  75
  76         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  77
  78         * All *.c: More cleanup towards GNU format.
  79
  80         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
  81         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
  82         that bfd_vma is only guaranteed to be at least as big as a pointer.
  83
  84         (GMON_Record_tag): added explicit enumeration values to ensure
  85         compatibility across compilers.
  86
  87         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
  88         sizeof(char*).
  89
  90 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  91
  92         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
  93         of constructs GNU indent couldn't handle.  Block comments not yet
  94         rewritten in GNU format.
  95
  96         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
  97         binutils release.
  98
  99 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 100
 101         * symtab.c (symtab_finalize): ensure globals symbols really
 102         are favored over static ones---even if their name looks less
 103         preferable; this is important for HP-UX; for example, there
 104         is a static label Ltext_something that aliases the global
 105         symbol _start
 106
 107         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 108         output only; also, auto-scaling is now performed based on
 109         per-call, rather than total execution time, which is what it was
 110         meant to be.
 111
 112         * gprof.h (File_Format): new type.
 113
 114         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 115         sync with Cygnus version numbers though...
 116
 117         (long_options): renamed --gmon-info to --file-info, --width added,
 118         renamed --old-file-format to --file-format
 119         (main): dito; also added support to read prof files, but as
 120         mon_out_read() is not implemented, it's #ifdef'd out for now
 121
 122         (usage): update to reflect new options.
 123
 124         * gmon_io.c: replaced "old_file_format" by more general
 125         "file_format" option
 126
 127         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 128
 129         * core.c (core_sym_class): added back check for __gnu_compiled and
 130         ___gnu_compiled for the benefit of systems without
 131         bfd_find_nearest_line() support
 132
 133         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 134         with section-relative addresses
 135
 136         (core_create_function_syms): get_src_info() calls are currently
 137         enabled for OSF/1 only.  It appears to work allright for SunOS
 138         4.1.x as well, but on SPARCs it gets painfully slow with the
 139         current implementation of aout_32_find_nearest_line();
 140         unfortunately, this means that static functions will not have their
 141         filename printed in the call-graph function index; line-level
 142         profiling should still work, but requires some patience
 143
 144         * cg_print.c (cg_print_index): sanitized printing of index when
 145         using FSF-style output; in particular, output width is now controlled
 146         via option --width and the function tries hard to keep columns
 147         aligned even in the presence of (occasional) long names
 148
 149         * NOTES: a first shot at updating the documentation.
 150
 151 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 152
 153         * core.c (core_create_function_syms): fixed computation of min_vma
 154         and max_vma.
 155
 156         * *.c: removed rcsid.
 157
 158 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 159
 160         * Lots of changes from David Mosberger-Tang:
 161
 162         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 163
 164         * gprof.c (main): put parentheses around & within &&.
 165
 166         * basic_blocks.c (bb_read_rec): print warning message (once) when
 167         ignoring basic-block execution counts.
 168
 169         * source.c (source_file_lookup_name): corrected second argument to
 170         strcmp().
 171
 172         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 173         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 174
 175         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 176         supported both for old and new (versioned) gmon.out files.  Old
 177         files are identified as version 0.
 178
 179         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 180         long (instead of 4) because that is what OSF/1 v3.0 uses.
 181
 182         * core.c: minor fixes and debugging info changes.
 183
 184         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 185
 186         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 187         name of the text-section under HP-UX).
 188
 189         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 190         points one past the last sampling bin, so hist_scale should be
 191         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 192         hist_num_bins - 1".
 193
 194         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 195         hist_num_bins.
 196
 197         * configure.in: added alpha-*-*) for per-target config.
 198
 199         * alpha.c, alpha.h: created.
 200
 201         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 202
 203         * core.c (core_create_function_syms, core_create_line_syms):
 204         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 205         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 206         addr) continues to guarantee not to return 0 on any address.  It
 207         also avoids incorrectly crediting the first/last symbol in the
 208         text-space.
 209
 210         * core.c (core_create_line_syms): always create function symbols
 211         first, then merge in line symbols; this is so that if parts of the
 212         program were compiled without -g, function-level symbols are
 213         available still.
 214
 215         * utils.c (print_name_only): support for print_path added.
 216
 217         * symtab.c (cmp_addr): also use is_func flag in comparison.
 218         (symtab_finalize): return immediately when table empty; now
 219         more careful about getting rid of the right duplicate symbol.
 220
 221         * sparc.c (find_call): many fixes---this function was rather
 222         botched in binutils-2.4 already; it should work again.
 223
 224         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 225         not good to rely on get_src_info() to return distinct string
 226         pointers).
 227
 228         * search_list.c (search_list_append): added cast for xmalloc().
 229
 230         * hist.c: added explicit initialization to some of the global
 231         variables; fixed SItab (scales were off by a factor of 10).
 232
 233         * hist.h: include of bfd.h added.
 234
 235         * gprof.c, gprof.h (print_path): added.
 236
 237         * gprof.h (MAX): fixed.
 238
 239         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 240
 241         * gmon_io.c: added some casts to (long) so we can always print as %lx
 242
 243         * core.c (core_get_text_space): fixed to make it work.
 244
 245         * cg_print.c (cg_print_index): added support for print_path option.
 246
 247         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 248
 249         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 250         as some compilers complain (e.g., DEC's OSF/1 compiler)
 251
 252         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 253         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 254
 255         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 256
 257         * gprof.c: added "_mcount" to default_excluded_list.
 258         (main): if output_style==0 and there is either a histogram or a
 259         call-graph, always generate flat and call-graph, no matter what
 260         line_granularity is set to.
 261
 262         * source.c (source_file_lookup_name): if searching for sf->name
 263         fails, try again with filename obtained after stripping off any
 264         partial path from sf->name.
 265
 266         * gprof.h (SRCDEBUG): added.
 267
 268         * search_list.c (search_list_append): directories were added in wrong
 269         order.
 270
 271         * reimplemented selection mechanism from ground up; it is now possible
 272         to accurately control what gets included/excluded in each of the
 273         output styles;  a "symbol-specification" (spec) is the basic means
 274         to select a set of symbols; a spec has the syntax:
 275
 276           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 277           arc == spec/spec.
 278
 279         any of the terminal symbols can be empty, in which case they
 280         match anything (wildcards).  NAME is interpreted as a FILENAME
 281         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 282         with a digit, and as FUNCNAME otherwise.
 283
 284         For example, to get a call-graph display that ignores arcs
 285         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 286         show only arcs into bar() (no matter what the caller),
 287         you'd say "--graph=/bar"; and to get a call-graph without
 288         any arc info, you'd say "--graph=/";  similarly, to
 289         get a flat profile without mcount, you'd say "--no-flat=mcount"
 290         and to get a flat profile that shows includes all functions
 291         you'd say "--flat=""" (i.e., an empty spec)
 292
 293         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 294
 295         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 296
 297         * gmon_out.h: all headers now declared in terms of characters
 298           to avoid getting into trouble with different compilers introducing
 299           different amount of padding; the code already accessed the fields
 300           through bfd functions, so that didn't have to change.
 301
 302         * hist.c (hist_read_rec, hist_write_rec): added support for
 303           collection pc histograms measuring quantities other than time;
 304           the histogram header now includes a field that specifies the
 305           dimension of the quantity measured by the histogram bins
 306           (normally, this is "seconds", but other meaningful dimensions
 307            include such things as "I-cache misses", "instruction issue stalls"
 308            etc.); there is also a field to specify a one-character
 309           abbreviation for the dimension; in the case of time, this would
 310           be 's'; in most other cases it probably would be '1' (not a physical
 311           dimension).
 312
 313         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 314
 315         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 316           has become old_file_version; gmon_io.c now always supports old-style
 317           gmon.out files; it first tries to read gmon.out as a new version
 318           file, if that fails, it tries to read it in the old format;
 319           although not very likely, it is possible for gprof to mistake an
 320           old-style file as a new one (the first 4 bytes would have to
 321           be "gmon"---including the trailing '\0'); in that case, it is
 322           necessary to specify --old-file-version
 323
 324         * gprof.h: removed dependency on SYSV; the code now always uses
 325           strrchr(), memset(), and memcpy() and does not include either
 326           of string.h or strings.h; this should make gprof compile on
 327           any (Unix) system without configuration (per suggestion of
 328           raeburn@cygnus.com)
 329
 330         * gprof.c (usage): fixed location of --new-file-format option.
 331
 332         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 333
 334         * flat_bl.m: removed formfeed at end of file; the form-feed
 335           is now printed cg_print.c only when necessary.
 336
 337         * major rewrite of gprof---too many changes to mention all of
 338           them.  new features:
 339
 340         + -l now requests profiling at the line level (as opposed
 341           to function level); in this mode, gprof creates a "symbol"
 342           (aka name-list entry) for each line of source code, instead
 343            of one per function)
 344
 345         + support for a new gmon.out file format; the new format
 346           consists of a header with a magic and a version number,
 347           followed by a sequence of profile data; profile data
 348           can any of: (a) PC histogram, (b) call-graph arcs, or
 349           (c) basic-block execution counts; the version number makes
 350           it possible to extend gmon.out in a backwards compatible
 351           fashion
 352
 353         + support for tcov style annotated output: if the gmon.out file
 354           contains basic-block execution counts, the user can request
 355           the generation of annotated source files, much like Sun's
 356           tcov used to do
 357
 358         + long options
 359
 360         + new scheme to suppress symbols that aren't function names
 361           (e.g., avoids mistaking a goto label as a function)
 362
 363         + reorganized source code to make it more managable; as a
 364           side effect, gprof now compiles cleanly with "gcc -Wall"
 365
 366         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 367
 368         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 369         final cross-check to determine whether a static symbol should be
 370         considered as a function-name.
 371
 372         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 373
 374         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 375         stdin; this is useful if you wanna keep gmon.out files compressed;
 376         this way you can "gzcat" the compressed file into gprof.
 377
 378         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 379
 380         * basic_blocks.c (bb_annotate_source): added support for creating
 381         .tcov files when option flag_annotate_make_files is TRUE.
 382         (annotate_with_count): all counts less than the minimum count
 383         specified by -m are now annotated with hash-marks.
 384
 385         * gprof.c (main): -A is now followed by a string of option chars.
 386
 387         * basic_blocks.c (annotate_with_count): replaced b->count with
 388         cnt.
 389
 390         * source.c: flag_annotate_source replaced by source_lock_map.
 391
 392         * source.h: source_lock_map added.
 393
 394         * gprof.c (main): new command-line syntax: -S simply specifies
 395         which source-files user is interested in; -A requests annotated
 396         source files and -AA requests that all lines in a source file
 397         are annotated.
 398
 399         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 400
 401         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 402
 403         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 404         so s_lowpc etc. get declared.
 405
 406         * arcs.h (doarcs): created.
 407
 408         * arcs.c: reordered static functions such that they get defined
 409         before use.
 410
 411         * gprof.c (main): added options:
 412            -A: request annotation of all source lines (with -S)
 413            -m: minimum execution count (with default basic-block display)
 414            -N: force new file format (only if BSD_COMPATIBLE is defined)
 415            -S: annotate source file
 416            -t: set table length (with -S)
 417
 418         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 419         source.o time_hist.o
 420

 422
 423         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 424         on the fact being able to store a long in a double without loss of
 425         precision; this does not hold on machines with 64 bit longs and 64
 426         bit doubles.

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

 434 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 435
 436         * printgprof.c (printprof): Use free, not cfree.
 437         (printgprof, printindex): Ditto.
 438
 439 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 440
 441         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 442         decls extern to keep native HP compiler quiet.
 443
 444 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 445
 446         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 447         __gnu_compiled, for the benefit of systems which add a leading
 448         underscore.

 461         Allows compilation with -Dregister= for debugging.
 462
 463         * configure.in: Add ns532 support.

 482
 483         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 484         so flat_bl.c would make from flat_bl.m file.
 485
 486 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 487
 488         * Makefile.in (install-info): Check for gprof.info in build dir,

 496         makes (osf1) in which the value of MACHINE can not be changed.
 497         * config/*.mt: Changed appropriately.
 498
 499 Wed Mar 30 16:12:40 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 500
 501         * gprof.c (getsymtab): Change nosyms to long.  Rename
 502         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for

 601         * Makefile.in: fix install rule for $(PROG)
 602
 603 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 604
 605         * gprof.1: updated SYNOPSIS to match actual behavior.
 606
 607 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 608
 609         * gen-c-prog.awk:  New awk script, lightly changed from
 610         previously deleted make-c-prog.awk.  Converts a text file
 611         to a c function that prints that text.
 612         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 613         Inputs to gen-c-prog.awk, containing text describing
 614         gprof output.
 615         * blurbs.c:  Removed.  Use *_bl.c instead.
 616         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 617         from *_bl.m files.  Also, improve *clean rules.
 618         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 619
 620
 621 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 622
 623         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 624         output styles:  The default is similar to the old FSF gprof,
 625         while -T sets the variable bsd_style_output, which causes
 626         output matching Berkeley's gprof.  The biggest differences
 627         are that with the FSF style output, the flat profile comes
 628         before the call graph; numbers come before explanations;
 629         and there is less gratuitous white space.
 630         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 631         variable causes discarding of initial underscores when
 632         printing symbol names.  It is set unless there is a "main"
 633         symbol (without an underscore).
 634         * printfgprof.c:  New function printnameonly(), called
 635         by printname().  It handles stripping of initial '_',
 636         as well as C++ name-demangling.
 637         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 638         It is just as convenient to edit blurbs.c directly.
 639         * Makefile.in:  Removed rule for making blurbs.c.
 640         * blurbs.c:  This is now a true source file (as opposed
 641         to being generated from gprof.callg and gprof.flat).
 642         Change style to use one long string literal, instead of
 643         one literal per output line.  Add FSF-style blurb for call graph.
 644
 645 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 646
 647         * Makefile.in: always create installation directories.

 654
 655         * Makefile.in:  removed installation of the now useless
 656         call.{flag,callg} files.
 657
 658         * gprof.1: now uses the standard man macros instead of the new BSD
 659         mandoc macros.
 660
 661 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 662
 663         * configure.in:  Remove host section, expand target section.
 664         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 665         * config/tmake-*:  Remove leftover crud.
 666
 667         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 668         * make-c-prog.awk:  which processes text files into C programs.
 669         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 670         to print blurbs.
 671         (printblurb):  Remove.
 672         * Makefile.in:  Infrastructure to build blurbs.
 673         * pathnames.h:  has been removed.  Gprof now has no filename
 674         dependencies in it.
 675         * gprof.c:  Lint.
 676

 685 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 686
 687         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 688         help in debugging the problem (with -DDEBUG)
 689         * gprof.c: symbol values are now real values, don't add the vma
 690         anymore. (done for solaris; should verify this on other platforms)
 691         * ChangeLog: created.
