  18 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
  19
  20         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
  21         that we're using autoconf.
  22
  23 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
  24
  25         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
  26         to proper type of "unsigned int *".
  27
  28 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  29
  30         * configure.in: Use changequote around use of [].
  31
  32 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  33
  34         * Makefile.in (distclean, realclean): Remove config.cache and
  35           config.log.
  36
  37 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  38
  39         * Makefile.in (Makefile): Added config.status to dependency list.
  40           (config.status): New target.
  41           (SHELL): New definition.
  42
  43 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  44
  45         * Makefile.in (install): Depend on "all".
  46
  47 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  48
  49         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
  50         to match configure script.
  51
  52 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  53
  54         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
  55           comment emitted by this script to gen-c-prog.awk.
  56
  57         * Makefile.in, configure.in: Converted to use autoconf.
  58         * configure: New file, generated with autoconf 2.3.
  59         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
  60           mt-tahoe, mt-vax}: Removed.
  61
  62 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  63
  64         * __bb_exit_func.c: New file, from David Mosberger-Tang.
  65
  66         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  67
  68         * All *.c: More cleanup towards GNU format.
  69
  70         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
  71         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
  72         that bfd_vma is only guaranteed to be at least as big as a pointer.
  73
  74         (GMON_Record_tag): added explicit enumeration values to ensure
  75         compatibility across compilers.
  76
  77         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
  78         sizeof(char*).
  79
  80 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  81
  82         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
  83         of constructs GNU indent couldn't handle.  Block comments not yet
  84         rewritten in GNU format.
  85
  86         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
  87         binutils release.
  88
  89 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  90
  91         * symtab.c (symtab_finalize): ensure globals symbols really
  92         are favored over static ones---even if their name looks less
  93         preferable; this is important for HP-UX; for example, there
  94         is a static label Ltext_something that aliases the global
  95         symbol _start
  96
  97         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
  98         output only; also, auto-scaling is now performed based on
  99         per-call, rather than total execution time, which is what it was
 100         meant to be.
 101
 102         * gprof.h (File_Format): new type.
 103
 104         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 105         sync with Cygnus version numbers though...
 106
 107         (long_options): renamed --gmon-info to --file-info, --width added,
 108         renamed --old-file-format to --file-format
 109         (main): dito; also added support to read prof files, but as
 110         mon_out_read() is not implemented, it's #ifdef'd out for now
 111
 112         (usage): update to reflect new options.
 113
 114         * gmon_io.c: replaced "old_file_format" by more general
 115         "file_format" option
 116
 117         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 118
 119         * core.c (core_sym_class): added back check for __gnu_compiled and
 120         ___gnu_compiled for the benefit of systems without
 121         bfd_find_nearest_line() support
 122
 123         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 124         with section-relative addresses
 125
 126         (core_create_function_syms): get_src_info() calls are currently
 127         enabled for OSF/1 only.  It appears to work allright for SunOS
 128         4.1.x as well, but on SPARCs it gets painfully slow with the
 129         current implementation of aout_32_find_nearest_line();
 130         unfortunately, this means that static functions will not have their
 131         filename printed in the call-graph function index; line-level
 132         profiling should still work, but requires some patience
 133
 134         * cg_print.c (cg_print_index): sanitized printing of index when
 135         using FSF-style output; in particular, output width is now controlled
 136         via option --width and the function tries hard to keep columns
 137         aligned even in the presence of (occasional) long names
 138
 139         * NOTES: a first shot at updating the documentation.
 140
 141 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 142
 143         * core.c (core_create_function_syms): fixed computation of min_vma
 144         and max_vma.
 145
 146         * *.c: removed rcsid.
 147
 148 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 149
 150         * Lots of changes from David Mosberger-Tang:
 151
 152         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 153
 154         * gprof.c (main): put parentheses around & within &&.
 155
 156         * basic_blocks.c (bb_read_rec): print warning message (once) when
 157         ignoring basic-block execution counts.
 158
 159         * source.c (source_file_lookup_name): corrected second argument to
 160         strcmp().
 161
 162         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 163         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 164
 165         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 166         supported both for old and new (versioned) gmon.out files.  Old
 167         files are identified as version 0.
 168
 169         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 170         long (instead of 4) because that is what OSF/1 v3.0 uses.
 171
 172         * core.c: minor fixes and debugging info changes.
 173
 174         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 175
 176         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 177         name of the text-section under HP-UX).
 178
 179         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 180         points one past the last sampling bin, so hist_scale should be
 181         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 182         hist_num_bins - 1".
 183
 184         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 185         hist_num_bins.
 186
 187         * configure.in: added alpha-*-*) for per-target config.
 188
 189         * alpha.c, alpha.h: created.
 190
 191         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 192
 193         * core.c (core_create_function_syms, core_create_line_syms):
 194         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 195         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 196         addr) continues to guarantee not to return 0 on any address.  It
 197         also avoids incorrectly crediting the first/last symbol in the
 198         text-space.
 199
 200         * core.c (core_create_line_syms): always create function symbols
 201         first, then merge in line symbols; this is so that if parts of the
 202         program were compiled without -g, function-level symbols are
 203         available still.
 204
 205         * utils.c (print_name_only): support for print_path added.
 206
 207         * symtab.c (cmp_addr): also use is_func flag in comparison.
 208         (symtab_finalize): return immediately when table empty; now
 209         more careful about getting rid of the right duplicate symbol.
 210
 211         * sparc.c (find_call): many fixes---this function was rather
 212         botched in binutils-2.4 already; it should work again.
 213
 214         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 215         not good to rely on get_src_info() to return distinct string
 216         pointers).
 217
 218         * search_list.c (search_list_append): added cast for xmalloc().
 219
 220         * hist.c: added explicit initialization to some of the global
 221         variables; fixed SItab (scales were off by a factor of 10).
 222
 223         * hist.h: include of bfd.h added.
 224
 225         * gprof.c, gprof.h (print_path): added.
 226
 227         * gprof.h (MAX): fixed.
 228
 229         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 230
 231         * gmon_io.c: added some casts to (long) so we can always print as %lx
 232
 233         * core.c (core_get_text_space): fixed to make it work.
 234
 235         * cg_print.c (cg_print_index): added support for print_path option.
 236
 237         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 238
 239         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 240         as some compilers complain (e.g., DEC's OSF/1 compiler)
 241
 242         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 243         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 244
 245         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 246
 247         * gprof.c: added "_mcount" to default_excluded_list.
 248         (main): if output_style==0 and there is either a histogram or a
 249         call-graph, always generate flat and call-graph, no matter what
 250         line_granularity is set to.
 251
 252         * source.c (source_file_lookup_name): if searching for sf->name
 253         fails, try again with filename obtained after stripping off any
 254         partial path from sf->name.
 255
 256         * gprof.h (SRCDEBUG): added.
 257
 258         * search_list.c (search_list_append): directories were added in wrong
 259         order.
 260
 261         * reimplemented selection mechanism from ground up; it is now possible
 262         to accurately control what gets included/excluded in each of the
 263         output styles;  a "symbol-specification" (spec) is the basic means
 264         to select a set of symbols; a spec has the syntax:
 265
 266           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 267           arc == spec/spec.
 268
 269         any of the terminal symbols can be empty, in which case they
 270         match anything (wildcards).  NAME is interpreted as a FILENAME
 271         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 272         with a digit, and as FUNCNAME otherwise.
 273
 274         For example, to get a call-graph display that ignores arcs
 275         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 276         show only arcs into bar() (no matter what the caller),
 277         you'd say "--graph=/bar"; and to get a call-graph without
 278         any arc info, you'd say "--graph=/";  similarly, to
 279         get a flat profile without mcount, you'd say "--no-flat=mcount"
 280         and to get a flat profile that shows includes all functions
 281         you'd say "--flat=""" (i.e., an empty spec)
 282
 283         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 284
 285         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 286
 287         * gmon_out.h: all headers now declared in terms of characters
 288           to avoid getting into trouble with different compilers introducing
 289           different amount of padding; the code already accessed the fields
 290           through bfd functions, so that didn't have to change.
 291
 292         * hist.c (hist_read_rec, hist_write_rec): added support for
 293           collection pc histograms measuring quantities other than time;
 294           the histogram header now includes a field that specifies the
 295           dimension of the quantity measured by the histogram bins
 296           (normally, this is "seconds", but other meaningful dimensions
 297            include such things as "I-cache misses", "instruction issue stalls"
 298            etc.); there is also a field to specify a one-character
 299           abbreviation for the dimension; in the case of time, this would
 300           be 's'; in most other cases it probably would be '1' (not a physical
 301           dimension).
 302
 303         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 304
 305         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 306           has become old_file_version; gmon_io.c now always supports old-style
 307           gmon.out files; it first tries to read gmon.out as a new version
 308           file, if that fails, it tries to read it in the old format;
 309           although not very likely, it is possible for gprof to mistake an
 310           old-style file as a new one (the first 4 bytes would have to
 311           be "gmon"---including the trailing '\0'); in that case, it is
 312           necessary to specify --old-file-version
 313
 314         * gprof.h: removed dependency on SYSV; the code now always uses
 315           strrchr(), memset(), and memcpy() and does not include either
 316           of string.h or strings.h; this should make gprof compile on
 317           any (Unix) system without configuration (per suggestion of
 318           raeburn@cygnus.com)
 319
 320         * gprof.c (usage): fixed location of --new-file-format option.
 321
 322         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 323
 324         * flat_bl.m: removed formfeed at end of file; the form-feed
 325           is now printed cg_print.c only when necessary.
 326
 327         * major rewrite of gprof---too many changes to mention all of
 328           them.  new features:
 329
 330         + -l now requests profiling at the line level (as opposed
 331           to function level); in this mode, gprof creates a "symbol"
 332           (aka name-list entry) for each line of source code, instead
 333            of one per function)
 334
 335         + support for a new gmon.out file format; the new format
 336           consists of a header with a magic and a version number,
 337           followed by a sequence of profile data; profile data
 338           can any of: (a) PC histogram, (b) call-graph arcs, or
 339           (c) basic-block execution counts; the version number makes
 340           it possible to extend gmon.out in a backwards compatible
 341           fashion
 342
 343         + support for tcov style annotated output: if the gmon.out file
 344           contains basic-block execution counts, the user can request
 345           the generation of annotated source files, much like Sun's
 346           tcov used to do
 347
 348         + long options
 349
 350         + new scheme to suppress symbols that aren't function names
 351           (e.g., avoids mistaking a goto label as a function)
 352
 353         + reorganized source code to make it more managable; as a
 354           side effect, gprof now compiles cleanly with "gcc -Wall"
 355
 356         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 357
 358         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 359         final cross-check to determine whether a static symbol should be
 360         considered as a function-name.

 362         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 363
 364         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 365         stdin; this is useful if you wanna keep gmon.out files compressed;
 366         this way you can "gzcat" the compressed file into gprof.
 367
 368         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 369
 370         * basic_blocks.c (bb_annotate_source): added support for creating
 371         .tcov files when option flag_annotate_make_files is TRUE.
 372         (annotate_with_count): all counts less than the minimum count
 373         specified by -m are now annotated with hash-marks.
 374
 375         * gprof.c (main): -A is now followed by a string of option chars.
 376
 377         * basic_blocks.c (annotate_with_count): replaced b->count with
 378         cnt.
 379
 380         * source.c: flag_annotate_source replaced by source_lock_map.
 381
 382         * source.h: source_lock_map added.
 383
 384         * gprof.c (main): new command-line syntax: -S simply specifies
 385         which source-files user is interested in; -A requests annotated
 386         source files and -AA requests that all lines in a source file
 387         are annotated.
 388
 389         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 390
 391         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 392
 393         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 394         so s_lowpc etc. get declared.
 395
 396         * arcs.h (doarcs): created.
 397
 398         * arcs.c: reordered static functions such that they get defined
 399         before use.
 400
 401         * gprof.c (main): added options:
 402            -A: request annotation of all source lines (with -S)
 403            -m: minimum execution count (with default basic-block display)
 404            -N: force new file format (only if BSD_COMPATIBLE is defined)
 405            -S: annotate source file
 406            -t: set table length (with -S)
 407
 408         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 409         source.o time_hist.o

 412
 413         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 414         on the fact being able to store a long in a double without loss of
 415         precision; this does not hold on machines with 64 bit longs and 64
 416         bit doubles.

 435
 436         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as

 472
 473         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 474         so flat_bl.c would make from flat_bl.m file.
 475
 476 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)

 489 Wed Mar 30 16:12:40 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 490
 491         * gprof.c (getsymtab): Change nosyms to long.  Rename
 492         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for

 592
 593 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 594
 595         * gprof.1: updated SYNOPSIS to match actual behavior.
 596
 597 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 598
 599         * gen-c-prog.awk:  New awk script, lightly changed from
 600         previously deleted make-c-prog.awk.  Converts a text file
 601         to a c function that prints that text.
 602         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 603         Inputs to gen-c-prog.awk, containing text describing
 604         gprof output.
 605         * blurbs.c:  Removed.  Use *_bl.c instead.
 606         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 607         from *_bl.m files.  Also, improve *clean rules.
 608         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 609
 610
 611 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 612
 613         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 614         output styles:  The default is similar to the old FSF gprof,
 615         while -T sets the variable bsd_style_output, which causes
 616         output matching Berkeley's gprof.  The biggest differences
 617         are that with the FSF style output, the flat profile comes
 618         before the call graph; numbers come before explanations;
 619         and there is less gratuitous white space.
 620         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 621         variable causes discarding of initial underscores when
 622         printing symbol names.  It is set unless there is a "main"
 623         symbol (without an underscore).
 624         * printfgprof.c:  New function printnameonly(), called
 625         by printname().  It handles stripping of initial '_',
 626         as well as C++ name-demangling.
 627         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 628         It is just as convenient to edit blurbs.c directly.
 629         * Makefile.in:  Removed rule for making blurbs.c.
 630         * blurbs.c:  This is now a true source file (as opposed
 631         to being generated from gprof.callg and gprof.flat).
 632         Change style to use one long string literal, instead of
 633         one literal per output line.  Add FSF-style blurb for call graph.
 634
 635 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 636
 637         * Makefile.in: always create installation directories.

 644
 645         * Makefile.in:  removed installation of the now useless
 646         call.{flag,callg} files.
 647
 648         * gprof.1: now uses the standard man macros instead of the new BSD
 649         mandoc macros.
 650
 651 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 652
 653         * configure.in:  Remove host section, expand target section.
 654         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 655         * config/tmake-*:  Remove leftover crud.
 656
 657         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 658         * make-c-prog.awk:  which processes text files into C programs.
 659         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 660         to print blurbs.
 661         (printblurb):  Remove.
 662         * Makefile.in:  Infrastructure to build blurbs.
 663         * pathnames.h:  has been removed.  Gprof now has no filename
 664         dependencies in it.
 665         * gprof.c:  Lint.
 666

 675 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 676
 677         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 678         help in debugging the problem (with -DDEBUG)
 679         * gprof.c: symbol values are now real values, don't add the vma
 680         anymore. (done for solaris; should verify this on other platforms)
 681         * ChangeLog: created.
