   1 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
   2
   3         * Makefile.in (install): Depend on "all".
   4
   5 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
   6
   7         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
   8         to match configure script.
   9
  10 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  11
  12         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
  13           comment emitted by this script to gen-c-prog.awk.
  14
  15         * Makefile.in, configure.in: Converted to use autoconf.
  16         * configure: New file, generated with autoconf 2.3.
  17         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
  18           mt-tahoe, mt-vax}: Removed.
  19
  20 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  21
  22         * __bb_exit_func.c: New file, from David Mosberger-Tang.
  23
  24         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  25
  26         * All *.c: More cleanup towards GNU format.
  27
  28         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
  29         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
  30         that bfd_vma is only guaranteed to be at least as big as a pointer.
  31
  32         (GMON_Record_tag): added explicit enumeration values to ensure
  33         compatibility across compilers.
  34
  35         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
  36         sizeof(char*).
  37
  38 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  39
  40         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
  41         of constructs GNU indent couldn't handle.  Block comments not yet
  42         rewritten in GNU format.
  43
  44         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
  45         binutils release.
  46
  47 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  48
  49         * symtab.c (symtab_finalize): ensure globals symbols really
  50         are favored over static ones---even if their name looks less
  51         preferable; this is important for HP-UX; for example, there
  52         is a static label Ltext_something that aliases the global
  53         symbol _start
  54
  55         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
  56         output only; also, auto-scaling is now performed based on
  57         per-call, rather than total execution time, which is what it was
  58         meant to be.
  59
  60         * gprof.h (File_Format): new type.
  61
  62         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
  63         sync with Cygnus version numbers though...
  64
  65         (long_options): renamed --gmon-info to --file-info, --width added,
  66         renamed --old-file-format to --file-format
  67         (main): dito; also added support to read prof files, but as
  68         mon_out_read() is not implemented, it's #ifdef'd out for now
  69
  70         (usage): update to reflect new options.
  71
  72         * gmon_io.c: replaced "old_file_format" by more general
  73         "file_format" option
  74
  75         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
  76
  77         * core.c (core_sym_class): added back check for __gnu_compiled and
  78         ___gnu_compiled for the benefit of systems without
  79         bfd_find_nearest_line() support
  80
  81         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
  82         with section-relative addresses
  83
  84         (core_create_function_syms): get_src_info() calls are currently
  85         enabled for OSF/1 only.  It appears to work allright for SunOS
  86         4.1.x as well, but on SPARCs it gets painfully slow with the
  87         current implementation of aout_32_find_nearest_line();
  88         unfortunately, this means that static functions will not have their
  89         filename printed in the call-graph function index; line-level
  90         profiling should still work, but requires some patience
  91
  92         * cg_print.c (cg_print_index): sanitized printing of index when
  93         using FSF-style output; in particular, output width is now controlled
  94         via option --width and the function tries hard to keep columns
  95         aligned even in the presence of (occasional) long names
  96
  97         * NOTES: a first shot at updating the documentation.
  98
  99 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 100
 101         * core.c (core_create_function_syms): fixed computation of min_vma
 102         and max_vma.
 103
 104         * *.c: removed rcsid.
 105
 106 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 107
 108         * Lots of changes from David Mosberger-Tang:
 109
 110         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 111
 112         * gprof.c (main): put parentheses around & within &&.
 113
 114         * basic_blocks.c (bb_read_rec): print warning message (once) when
 115         ignoring basic-block execution counts.
 116
 117         * source.c (source_file_lookup_name): corrected second argument to
 118         strcmp().
 119
 120         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 121         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 122
 123         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 124         supported both for old and new (versioned) gmon.out files.  Old
 125         files are identified as version 0.
 126
 127         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 128         long (instead of 4) because that is what OSF/1 v3.0 uses.
 129
 130         * core.c: minor fixes and debugging info changes.
 131
 132         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 133
 134         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 135         name of the text-section under HP-UX).
 136
 137         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 138         points one past the last sampling bin, so hist_scale should be
 139         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 140         hist_num_bins - 1".
 141
 142         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 143         hist_num_bins.
 144
 145         * configure.in: added alpha-*-*) for per-target config.
 146
 147         * alpha.c, alpha.h: created.
 148
 149         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 150
 151         * core.c (core_create_function_syms, core_create_line_syms):
 152         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 153         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 154         addr) continues to guarantee not to return 0 on any address.  It
 155         also avoids incorrectly crediting the first/last symbol in the
 156         text-space.
 157
 158         * core.c (core_create_line_syms): always create function symbols
 159         first, then merge in line symbols; this is so that if parts of the
 160         program were compiled without -g, function-level symbols are
 161         available still.
 162
 163         * utils.c (print_name_only): support for print_path added.
 164
 165         * symtab.c (cmp_addr): also use is_func flag in comparison.
 166         (symtab_finalize): return immediately when table empty; now
 167         more careful about getting rid of the right duplicate symbol.
 168
 169         * sparc.c (find_call): many fixes---this function was rather
 170         botched in binutils-2.4 already; it should work again.
 171
 172         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 173         not good to rely on get_src_info() to return distinct string
 174         pointers).
 175
 176         * search_list.c (search_list_append): added cast for xmalloc().
 177
 178         * hist.c: added explicit initialization to some of the global
 179         variables; fixed SItab (scales were off by a factor of 10).
 180
 181         * hist.h: include of bfd.h added.
 182
 183         * gprof.c, gprof.h (print_path): added.
 184
 185         * gprof.h (MAX): fixed.
 186
 187         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 188
 189         * gmon_io.c: added some casts to (long) so we can always print as %lx
 190
 191         * core.c (core_get_text_space): fixed to make it work.
 192
 193         * cg_print.c (cg_print_index): added support for print_path option.
 194
 195         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 196
 197         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 198         as some compilers complain (e.g., DEC's OSF/1 compiler)
 199
 200         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 201         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 202
 203         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 204
 205         * gprof.c: added "_mcount" to default_excluded_list.
 206         (main): if output_style==0 and there is either a histogram or a
 207         call-graph, always generate flat and call-graph, no matter what
 208         line_granularity is set to.
 209
 210         * source.c (source_file_lookup_name): if searching for sf->name
 211         fails, try again with filename obtained after stripping off any
 212         partial path from sf->name.
 213
 214         * gprof.h (SRCDEBUG): added.
 215
 216         * search_list.c (search_list_append): directories were added in wrong
 217         order.
 218
 219         * reimplemented selection mechanism from ground up; it is now possible
 220         to accurately control what gets included/excluded in each of the
 221         output styles;  a "symbol-specification" (spec) is the basic means
 222         to select a set of symbols; a spec has the syntax:
 223
 224           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 225           arc == spec/spec.
 226
 227         any of the terminal symbols can be empty, in which case they
 228         match anything (wildcards).  NAME is interpreted as a FILENAME
 229         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 230         with a digit, and as FUNCNAME otherwise.
 231
 232         For example, to get a call-graph display that ignores arcs
 233         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 234         show only arcs into bar() (no matter what the caller),
 235         you'd say "--graph=/bar"; and to get a call-graph without
 236         any arc info, you'd say "--graph=/";  similarly, to
 237         get a flat profile without mcount, you'd say "--no-flat=mcount"
 238         and to get a flat profile that shows includes all functions
 239         you'd say "--flat=""" (i.e., an empty spec)
 240
 241         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 242
 243         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 244
 245         * gmon_out.h: all headers now declared in terms of characters
 246           to avoid getting into trouble with different compilers introducing
 247           different amount of padding; the code already accessed the fields
 248           through bfd functions, so that didn't have to change.
 249
 250         * hist.c (hist_read_rec, hist_write_rec): added support for
 251           collection pc histograms measuring quantities other than time;
 252           the histogram header now includes a field that specifies the
 253           dimension of the quantity measured by the histogram bins
 254           (normally, this is "seconds", but other meaningful dimensions
 255            include such things as "I-cache misses", "instruction issue stalls"
 256            etc.); there is also a field to specify a one-character
 257           abbreviation for the dimension; in the case of time, this would
 258           be 's'; in most other cases it probably would be '1' (not a physical
 259           dimension).
 260
 261         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 262
 263         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 264           has become old_file_version; gmon_io.c now always supports old-style
 265           gmon.out files; it first tries to read gmon.out as a new version
 266           file, if that fails, it tries to read it in the old format;
 267           although not very likely, it is possible for gprof to mistake an
 268           old-style file as a new one (the first 4 bytes would have to
 269           be "gmon"---including the trailing '\0'); in that case, it is
 270           necessary to specify --old-file-version
 271
 272         * gprof.h: removed dependency on SYSV; the code now always uses
 273           strrchr(), memset(), and memcpy() and does not include either
 274           of string.h or strings.h; this should make gprof compile on
 275           any (Unix) system without configuration (per suggestion of
 276           raeburn@cygnus.com)
 277
 278         * gprof.c (usage): fixed location of --new-file-format option.
 279
 280         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 281
 282         * flat_bl.m: removed formfeed at end of file; the form-feed
 283           is now printed cg_print.c only when necessary.
 284
 285         * major rewrite of gprof---too many changes to mention all of
 286           them.  new features:
 287
 288         + -l now requests profiling at the line level (as opposed
 289           to function level); in this mode, gprof creates a "symbol"
 290           (aka name-list entry) for each line of source code, instead
 291            of one per function)
 292
 293         + support for a new gmon.out file format; the new format
 294           consists of a header with a magic and a version number,
 295           followed by a sequence of profile data; profile data
 296           can any of: (a) PC histogram, (b) call-graph arcs, or
 297           (c) basic-block execution counts; the version number makes
 298           it possible to extend gmon.out in a backwards compatible
 299           fashion
 300
 301         + support for tcov style annotated output: if the gmon.out file
 302           contains basic-block execution counts, the user can request
 303           the generation of annotated source files, much like Sun's
 304           tcov used to do
 305
 306         + long options
 307
 308         + new scheme to suppress symbols that aren't function names
 309           (e.g., avoids mistaking a goto label as a function)
 310
 311         + reorganized source code to make it more managable; as a
 312           side effect, gprof now compiles cleanly with "gcc -Wall"
 313
 314         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 315
 316         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 317         final cross-check to determine whether a static symbol should be
 318         considered as a function-name.
 319
 320         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 321
 322         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 323         stdin; this is useful if you wanna keep gmon.out files compressed;
 324         this way you can "gzcat" the compressed file into gprof.
 325
 326         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 327
 328         * basic_blocks.c (bb_annotate_source): added support for creating
 329         .tcov files when option flag_annotate_make_files is TRUE.
 330         (annotate_with_count): all counts less than the minimum count
 331         specified by -m are now annotated with hash-marks.
 332
 333         * gprof.c (main): -A is now followed by a string of option chars.
 334
 335         * basic_blocks.c (annotate_with_count): replaced b->count with
 336         cnt.
 337
 338         * source.c: flag_annotate_source replaced by source_lock_map.
 339
 340         * source.h: source_lock_map added.
 341
 342         * gprof.c (main): new command-line syntax: -S simply specifies
 343         which source-files user is interested in; -A requests annotated
 344         source files and -AA requests that all lines in a source file
 345         are annotated.
 346
 347         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 348
 349         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 350
 351         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 352         so s_lowpc etc. get declared.
 353
 354         * arcs.h (doarcs): created.
 355
 356         * arcs.c: reordered static functions such that they get defined
 357         before use.
 358
 359         * gprof.c (main): added options:
 360            -A: request annotation of all source lines (with -S)
 361            -m: minimum execution count (with default basic-block display)

 370
 371         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 372         on the fact being able to store a long in a double without loss of
 373         precision; this does not hold on machines with 64 bit longs and 64
 374         bit doubles.

 430
 431         * Makefile.in (.m.c:):  Added .SUFFIXES : .m

 433
 434 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)

 550
 551 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 552
 553         * gprof.1: updated SYNOPSIS to match actual behavior.
 554
 555 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 556
 557         * gen-c-prog.awk:  New awk script, lightly changed from
 558         previously deleted make-c-prog.awk.  Converts a text file
 559         to a c function that prints that text.
 560         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 561         Inputs to gen-c-prog.awk, containing text describing
 562         gprof output.
 563         * blurbs.c:  Removed.  Use *_bl.c instead.
 564         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 565         from *_bl.m files.  Also, improve *clean rules.
 566         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 567
 568
 569 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 570
 571         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 572         output styles:  The default is similar to the old FSF gprof,
 573         while -T sets the variable bsd_style_output, which causes
 574         output matching Berkeley's gprof.  The biggest differences
 575         are that with the FSF style output, the flat profile comes
 576         before the call graph; numbers come before explanations;
 577         and there is less gratuitous white space.
 578         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 579         variable causes discarding of initial underscores when
 580         printing symbol names.  It is set unless there is a "main"
 581         symbol (without an underscore).
 582         * printfgprof.c:  New function printnameonly(), called
 583         by printname().  It handles stripping of initial '_',
 584         as well as C++ name-demangling.
 585         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 586         It is just as convenient to edit blurbs.c directly.
 587         * Makefile.in:  Removed rule for making blurbs.c.
 588         * blurbs.c:  This is now a true source file (as opposed
 589         to being generated from gprof.callg and gprof.flat).
 590         Change style to use one long string literal, instead of
 591         one literal per output line.  Add FSF-style blurb for call graph.
 592
 593 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 594
 595         * Makefile.in: always create installation directories.

 604         call.{flag,callg} files.
 605
 606         * gprof.1: now uses the standard man macros instead of the new BSD
 607         mandoc macros.
 608
 609 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 610
 611         * configure.in:  Remove host section, expand target section.
 612         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 613         * config/tmake-*:  Remove leftover crud.
 614
 615         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 616         * make-c-prog.awk:  which processes text files into C programs.
 617         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 618         to print blurbs.
 619         (printblurb):  Remove.
 620         * Makefile.in:  Infrastructure to build blurbs.
 621         * pathnames.h:  has been removed.  Gprof now has no filename
 622         dependencies in it.
 623         * gprof.c:  Lint.
 624

 632
 633 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 634
 635         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 636         help in debugging the problem (with -DDEBUG)
 637         * gprof.c: symbol values are now real values, don't add the vma
 638         anymore. (done for solaris; should verify this on other platforms)
 639         * ChangeLog: created.
