gprof/ChangeLog

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

 366
 367         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 368         on the fact being able to store a long in a double without loss of
 369         precision; this does not hold on machines with 64 bit longs and 64
 370         bit doubles.

 546
 547 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 548
 549         * gprof.1: updated SYNOPSIS to match actual behavior.
 550
 551 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 552
 553         * gen-c-prog.awk:  New awk script, lightly changed from
 554         previously deleted make-c-prog.awk.  Converts a text file
 555         to a c function that prints that text.
 556         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 557         Inputs to gen-c-prog.awk, containing text describing
 558         gprof output.
 559         * blurbs.c:  Removed.  Use *_bl.c instead.
 560         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 561         from *_bl.m files.  Also, improve *clean rules.
 562         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 563
 564
 565 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 566
 567         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 568         output styles:  The default is similar to the old FSF gprof,
 569         while -T sets the variable bsd_style_output, which causes
 570         output matching Berkeley's gprof.  The biggest differences
 571         are that with the FSF style output, the flat profile comes
 572         before the call graph; numbers come before explanations;
 573         and there is less gratuitous white space.
 574         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 575         variable causes discarding of initial underscores when
 576         printing symbol names.  It is set unless there is a "main"
 577         symbol (without an underscore).
 578         * printfgprof.c:  New function printnameonly(), called
 579         by printname().  It handles stripping of initial '_',
 580         as well as C++ name-demangling.
 581         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 582         It is just as convenient to edit blurbs.c directly.
 583         * Makefile.in:  Removed rule for making blurbs.c.
 584         * blurbs.c:  This is now a true source file (as opposed
 585         to being generated from gprof.callg and gprof.flat).
 586         Change style to use one long string literal, instead of
 587         one literal per output line.  Add FSF-style blurb for call graph.
 588
 589 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 590
 591         * Makefile.in: always create installation directories.

 600         call.{flag,callg} files.
 601
 602         * gprof.1: now uses the standard man macros instead of the new BSD
 603         mandoc macros.
 604
 605 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 606
 607         * configure.in:  Remove host section, expand target section.
 608         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 609         * config/tmake-*:  Remove leftover crud.
 610
 611         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 612         * make-c-prog.awk:  which processes text files into C programs.
 613         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 614         to print blurbs.
 615         (printblurb):  Remove.
 616         * Makefile.in:  Infrastructure to build blurbs.
 617         * pathnames.h:  has been removed.  Gprof now has no filename
 618         dependencies in it.
 619         * gprof.c:  Lint.

 629 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 630
 631         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 632         help in debugging the problem (with -DDEBUG)
 633         * gprof.c: symbol values are now real values, don't add the vma
 634         anymore. (done for solaris; should verify this on other platforms)
 635         * ChangeLog: created.
