  31
  32 Sun Dec 24 21:32:27 1995  Jeffrey A Law  (law@cygnus.com)
  33
  34         * core.c (core_sym_class): Ignore symbols without BSF_FUNCTION

  45         name.
  46
  47         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
  48         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
  49         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
  50
  51         * vax.c: Don't include vax.h here.
  52

  65 Wed Nov  1 12:51:21 1995  Per Bothner  <bothner@kalessin.cygnus.com>
  66
  67         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
  68         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
  69         on info).
  70
  71 Wed Nov  1 15:23:15 1995  Manfred Hollstein KS/EF4A 60/1F/110 #40283  <manfred@lts.sel.alcatel.de>

  86
  87         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
  88         style output format to make it consistent.
  89         * dummy.c (find_call): Fix typo in error message.
  90
  91 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
  92

  94         realclean.
  95

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

 376
 377         * gmon_out.h: all headers now declared in terms of characters
 378           to avoid getting into trouble with different compilers introducing
 379           different amount of padding; the code already accessed the fields
 380           through bfd functions, so that didn't have to change.
 381
 382         * hist.c (hist_read_rec, hist_write_rec): added support for
 383           collection pc histograms measuring quantities other than time;
 384           the histogram header now includes a field that specifies the
 385           dimension of the quantity measured by the histogram bins
 386           (normally, this is "seconds", but other meaningful dimensions
 387            include such things as "I-cache misses", "instruction issue stalls"
 388            etc.); there is also a field to specify a one-character
 389           abbreviation for the dimension; in the case of time, this would
 390           be 's'; in most other cases it probably would be '1' (not a physical
 391           dimension).

 393         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 394
 395         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 396           has become old_file_version; gmon_io.c now always supports old-style
 397           gmon.out files; it first tries to read gmon.out as a new version
 398           file, if that fails, it tries to read it in the old format;
 399           although not very likely, it is possible for gprof to mistake an
 400           old-style file as a new one (the first 4 bytes would have to
 401           be "gmon"---including the trailing '\0'); in that case, it is
 402           necessary to specify --old-file-version
 403
 404         * gprof.h: removed dependency on SYSV; the code now always uses
 405           strrchr(), memset(), and memcpy() and does not include either
 406           of string.h or strings.h; this should make gprof compile on
 407           any (Unix) system without configuration (per suggestion of
 408           raeburn@cygnus.com)
 409
 410         * gprof.c (usage): fixed location of --new-file-format option.
 411
 412         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 413
 414         * flat_bl.m: removed formfeed at end of file; the form-feed
 415           is now printed cg_print.c only when necessary.
 416
 417         * major rewrite of gprof---too many changes to mention all of
 418           them.  new features:
 419
 420         + -l now requests profiling at the line level (as opposed
 421           to function level); in this mode, gprof creates a "symbol"
 422           (aka name-list entry) for each line of source code, instead
 423            of one per function)
 424
 425         + support for a new gmon.out file format; the new format
 426           consists of a header with a magic and a version number,
 427           followed by a sequence of profile data; profile data
 428           can any of: (a) PC histogram, (b) call-graph arcs, or
 429           (c) basic-block execution counts; the version number makes
 430           it possible to extend gmon.out in a backwards compatible
 431           fashion
 432
 433         + support for tcov style annotated output: if the gmon.out file
 434           contains basic-block execution counts, the user can request
 435           the generation of annotated source files, much like Sun's
 436           tcov used to do
 437
 438         + long options
 439
 440         + new scheme to suppress symbols that aren't function names
 441           (e.g., avoids mistaking a goto label as a function)
 442
 443         + reorganized source code to make it more managable; as a
 444           side effect, gprof now compiles cleanly with "gcc -Wall"
 445
 446         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 447
 448         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 449         final cross-check to determine whether a static symbol should be
 450         considered as a function-name.
 451
 452         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 453
 454         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 455         stdin; this is useful if you wanna keep gmon.out files compressed;
 456         this way you can "gzcat" the compressed file into gprof.
 457
 458         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 459
 460         * basic_blocks.c (bb_annotate_source): added support for creating
 461         .tcov files when option flag_annotate_make_files is TRUE.
 462         (annotate_with_count): all counts less than the minimum count
 463         specified by -m are now annotated with hash-marks.
 464
 465         * gprof.c (main): -A is now followed by a string of option chars.
 466
 467         * basic_blocks.c (annotate_with_count): replaced b->count with
 468         cnt.
 469
 470         * source.c: flag_annotate_source replaced by source_lock_map.
 471
 472         * source.h: source_lock_map added.
 473
 474         * gprof.c (main): new command-line syntax: -S simply specifies
 475         which source-files user is interested in; -A requests annotated
 476         source files and -AA requests that all lines in a source file
 477         are annotated.
 478
 479         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 480
 481         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 482
 483         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 484         so s_lowpc etc. get declared.
 485
 486         * arcs.h (doarcs): created.
 487
 488         * arcs.c: reordered static functions such that they get defined
 489         before use.
 490
 491         * gprof.c (main): added options:
 492            -A: request annotation of all source lines (with -S)
 493            -m: minimum execution count (with default basic-block display)
 494            -N: force new file format (only if BSD_COMPATIBLE is defined)
 495            -S: annotate source file
 496            -t: set table length (with -S)
 497
 498         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 499         source.o time_hist.o

 502
 503         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 504         on the fact being able to store a long in a double without loss of
 505         precision; this does not hold on machines with 64 bit longs and 64
 506         bit doubles.

 582         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
 583         errors from bfd_get_symtab_upper_bound and

 686
 687 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 688
 689         * gen-c-prog.awk:  New awk script, lightly changed from
 690         previously deleted make-c-prog.awk.  Converts a text file
 691         to a c function that prints that text.
 692         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 693         Inputs to gen-c-prog.awk, containing text describing
 694         gprof output.
 695         * blurbs.c:  Removed.  Use *_bl.c instead.
 696         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 697         from *_bl.m files.  Also, improve *clean rules.
 698         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 701 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 702
 703         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 704         output styles:  The default is similar to the old FSF gprof,
 705         while -T sets the variable bsd_style_output, which causes
 706         output matching Berkeley's gprof.  The biggest differences
 707         are that with the FSF style output, the flat profile comes
 708         before the call graph; numbers come before explanations;
 709         and there is less gratuitous white space.
 710         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 711         variable causes discarding of initial underscores when
 712         printing symbol names.  It is set unless there is a "main"
 713         symbol (without an underscore).
 714         * printfgprof.c:  New function printnameonly(), called
 715         by printname().  It handles stripping of initial '_',
 716         as well as C++ name-demangling.
 717         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 718         It is just as convenient to edit blurbs.c directly.
 719         * Makefile.in:  Removed rule for making blurbs.c.
 720         * blurbs.c:  This is now a true source file (as opposed
 721         to being generated from gprof.callg and gprof.flat).
 722         Change style to use one long string literal, instead of
 723         one literal per output line.  Add FSF-style blurb for call graph.

 726
 727         * Makefile.in: always create installation directories.

 730
 731         * Makefile.in: change ${MACHINE} to $(MACHINE).

 734
 735         * Makefile.in:  removed installation of the now useless
 736         call.{flag,callg} files.
 737
 738         * gprof.1: now uses the standard man macros instead of the new BSD
 739         mandoc macros.

 741 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 742
 743         * configure.in:  Remove host section, expand target section.
 744         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 745         * config/tmake-*:  Remove leftover crud.
 746
 747         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 748         * make-c-prog.awk:  which processes text files into C programs.
 749         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 750         to print blurbs.
 751         (printblurb):  Remove.
 752         * Makefile.in:  Infrastructure to build blurbs.
 753         * pathnames.h:  has been removed.  Gprof now has no filename
 754         dependencies in it.
 755         * gprof.c:  Lint.

 765 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 766
 767         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 768         help in debugging the problem (with -DDEBUG)
 769         * gprof.c: symbol values are now real values, don't add the vma
 770         anymore. (done for solaris; should verify this on other platforms)
 771         * ChangeLog: created.
