gprof/ChangeLog

   1 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
   2
   3         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
   4         of constructs GNU indent couldn't handle.  Block comments not yet
   5         rewritten in GNU format.
   6
   7         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
   8         binutils release.
   9
  10 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  11
  12         * symtab.c (symtab_finalize): ensure globals symbols really
  13         are favored over static ones---even if their name looks less
  14         preferable; this is important for HP-UX; for example, there
  15         is a static label Ltext_something that aliases the global
  16         symbol _start
  17
  18         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
  19         output only; also, auto-scaling is now performed based on
  20         per-call, rather than total execution time, which is what it was
  21         meant to be.
  22
  23         * gprof.h (File_Format): new type.
  24
  25         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
  26         sync with Cygnus version numbers though...
  27
  28         (long_options): renamed --gmon-info to --file-info, --width added,
  29         renamed --old-file-format to --file-format
  30         (main): dito; also added support to read prof files, but as
  31         mon_out_read() is not implemented, it's #ifdef'd out for now
  32
  33         (usage): update to reflect new options.
  34
  35         * gmon_io.c: replaced "old_file_format" by more general
  36         "file_format" option
  37
  38         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
  39
  40         * core.c (core_sym_class): added back check for __gnu_compiled and
  41         ___gnu_compiled for the benefit of systems without
  42         bfd_find_nearest_line() support
  43
  44         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
  45         with section-relative addresses
  46
  47         (core_create_function_syms): get_src_info() calls are currently
  48         enabled for OSF/1 only.  It appears to work allright for SunOS
  49         4.1.x as well, but on SPARCs it gets painfully slow with the
  50         current implementation of aout_32_find_nearest_line();
  51         unfortunately, this means that static functions will not have their
  52         filename printed in the call-graph function index; line-level
  53         profiling should still work, but requires some patience
  54
  55         * cg_print.c (cg_print_index): sanitized printing of index when
  56         using FSF-style output; in particular, output width is now controlled
  57         via option --width and the function tries hard to keep columns
  58         aligned even in the presence of (occasional) long names
  59
  60         * NOTES: a first shot at updating the documentation.
  61
  62 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  63
  64         * core.c (core_create_function_syms): fixed computation of min_vma
  65         and max_vma.
  66
  67         * *.c: removed rcsid.
  68
  69 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  70
  71         * Lots of changes from David Mosberger-Tang:
  72
  73         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  74
  75         * gprof.c (main): put parentheses around & within &&.
  76
  77         * basic_blocks.c (bb_read_rec): print warning message (once) when
  78         ignoring basic-block execution counts.
  79
  80         * source.c (source_file_lookup_name): corrected second argument to
  81         strcmp().
  82
  83         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
  84         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
  85
  86         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
  87         supported both for old and new (versioned) gmon.out files.  Old
  88         files are identified as version 0.
  89
  90         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
  91         long (instead of 4) because that is what OSF/1 v3.0 uses.
  92
  93         * core.c: minor fixes and debugging info changes.
  94
  95         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
  96
  97         * core.c (core_init): if .text cannot be found, try $CODE$ (the
  98         name of the text-section under HP-UX).
  99
 100         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 101         points one past the last sampling bin, so hist_scale should be
 102         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 103         hist_num_bins - 1".
 104
 105         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 106         hist_num_bins.
 107
 108         * configure.in: added alpha-*-*) for per-target config.
 109
 110         * alpha.c, alpha.h: created.
 111
 112         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 113
 114         * core.c (core_create_function_syms, core_create_line_syms):
 115         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 116         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 117         addr) continues to guarantee not to return 0 on any address.  It
 118         also avoids incorrectly crediting the first/last symbol in the
 119         text-space.
 120
 121         * core.c (core_create_line_syms): always create function symbols
 122         first, then merge in line symbols; this is so that if parts of the
 123         program were compiled without -g, function-level symbols are
 124         available still.
 125
 126         * utils.c (print_name_only): support for print_path added.
 127
 128         * symtab.c (cmp_addr): also use is_func flag in comparison.
 129         (symtab_finalize): return immediately when table empty; now
 130         more careful about getting rid of the right duplicate symbol.
 131
 132         * sparc.c (find_call): many fixes---this function was rather
 133         botched in binutils-2.4 already; it should work again.
 134
 135         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 136         not good to rely on get_src_info() to return distinct string
 137         pointers).
 138
 139         * search_list.c (search_list_append): added cast for xmalloc().
 140
 141         * hist.c: added explicit initialization to some of the global
 142         variables; fixed SItab (scales were off by a factor of 10).
 143
 144         * hist.h: include of bfd.h added.
 145
 146         * gprof.c, gprof.h (print_path): added.
 147
 148         * gprof.h (MAX): fixed.
 149
 150         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 151
 152         * gmon_io.c: added some casts to (long) so we can always print as %lx
 153
 154         * core.c (core_get_text_space): fixed to make it work.
 155
 156         * cg_print.c (cg_print_index): added support for print_path option.
 157
 158         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 159
 160         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 161         as some compilers complain (e.g., DEC's OSF/1 compiler)
 162
 163         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 164         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 165
 166         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 167
 168         * gprof.c: added "_mcount" to default_excluded_list.
 169         (main): if output_style==0 and there is either a histogram or a
 170         call-graph, always generate flat and call-graph, no matter what
 171         line_granularity is set to.
 172
 173         * source.c (source_file_lookup_name): if searching for sf->name
 174         fails, try again with filename obtained after stripping off any
 175         partial path from sf->name.
 176
 177         * gprof.h (SRCDEBUG): added.
 178
 179         * search_list.c (search_list_append): directories were added in wrong
 180         order.
 181
 182         * reimplemented selection mechanism from ground up; it is now possible
 183         to accurately control what gets included/excluded in each of the
 184         output styles;  a "symbol-specification" (spec) is the basic means
 185         to select a set of symbols; a spec has the syntax:
 186
 187           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 188           arc == spec/spec.
 189
 190         any of the terminal symbols can be empty, in which case they
 191         match anything (wildcards).  NAME is interpreted as a FILENAME
 192         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 193         with a digit, and as FUNCNAME otherwise.
 194
 195         For example, to get a call-graph display that ignores arcs
 196         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 197         show only arcs into bar() (no matter what the caller),
 198         you'd say "--graph=/bar"; and to get a call-graph without
 199         any arc info, you'd say "--graph=/";  similarly, to
 200         get a flat profile without mcount, you'd say "--no-flat=mcount"
 201         and to get a flat profile that shows includes all functions
 202         you'd say "--flat=""" (i.e., an empty spec)
 203
 204         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 205
 206         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 207
 208         * gmon_out.h: all headers now declared in terms of characters
 209           to avoid getting into trouble with different compilers introducing
 210           different amount of padding; the code already accessed the fields
 211           through bfd functions, so that didn't have to change.
 212
 213         * hist.c (hist_read_rec, hist_write_rec): added support for
 214           collection pc histograms measuring quantities other than time;
 215           the histogram header now includes a field that specifies the
 216           dimension of the quantity measured by the histogram bins
 217           (normally, this is "seconds", but other meaningful dimensions
 218            include such things as "I-cache misses", "instruction issue stalls"
 219            etc.); there is also a field to specify a one-character
 220           abbreviation for the dimension; in the case of time, this would
 221           be 's'; in most other cases it probably would be '1' (not a physical
 222           dimension).
 223
 224         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 225
 226         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 227           has become old_file_version; gmon_io.c now always supports old-style
 228           gmon.out files; it first tries to read gmon.out as a new version
 229           file, if that fails, it tries to read it in the old format;
 230           although not very likely, it is possible for gprof to mistake an
 231           old-style file as a new one (the first 4 bytes would have to
 232           be "gmon"---including the trailing '\0'); in that case, it is
 233           necessary to specify --old-file-version
 234
 235         * gprof.h: removed dependency on SYSV; the code now always uses
 236           strrchr(), memset(), and memcpy() and does not include either
 237           of string.h or strings.h; this should make gprof compile on
 238           any (Unix) system without configuration (per suggestion of
 239           raeburn@cygnus.com)
 240
 241         * gprof.c (usage): fixed location of --new-file-format option.
 242
 243         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 244
 245         * flat_bl.m: removed formfeed at end of file; the form-feed
 246           is now printed cg_print.c only when necessary.
 247
 248         * major rewrite of gprof---too many changes to mention all of
 249           them.  new features:
 250
 251         + -l now requests profiling at the line level (as opposed
 252           to function level); in this mode, gprof creates a "symbol"
 253           (aka name-list entry) for each line of source code, instead
 254            of one per function)
 255
 256         + support for a new gmon.out file format; the new format
 257           consists of a header with a magic and a version number,
 258           followed by a sequence of profile data; profile data
 259           can any of: (a) PC histogram, (b) call-graph arcs, or
 260           (c) basic-block execution counts; the version number makes
 261           it possible to extend gmon.out in a backwards compatible
 262           fashion
 263
 264         + support for tcov style annotated output: if the gmon.out file
 265           contains basic-block execution counts, the user can request
 266           the generation of annotated source files, much like Sun's
 267           tcov used to do
 268
 269         + long options
 270
 271         + new scheme to suppress symbols that aren't function names
 272           (e.g., avoids mistaking a goto label as a function)
 273
 274         + reorganized source code to make it more managable; as a
 275           side effect, gprof now compiles cleanly with "gcc -Wall"
 276
 277         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 278
 279         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 280         final cross-check to determine whether a static symbol should be
 281         considered as a function-name.
 282
 283         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 284
 285         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 286         stdin; this is useful if you wanna keep gmon.out files compressed;
 287         this way you can "gzcat" the compressed file into gprof.
 288
 289         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 290
 291         * basic_blocks.c (bb_annotate_source): added support for creating
 292         .tcov files when option flag_annotate_make_files is TRUE.
 293         (annotate_with_count): all counts less than the minimum count
 294         specified by -m are now annotated with hash-marks.
 295
 296         * gprof.c (main): -A is now followed by a string of option chars.
 297
 298         * basic_blocks.c (annotate_with_count): replaced b->count with
 299         cnt.
 300
 301         * source.c: flag_annotate_source replaced by source_lock_map.
 302
 303         * source.h: source_lock_map added.
 304
 305         * gprof.c (main): new command-line syntax: -S simply specifies
 306         which source-files user is interested in; -A requests annotated
 307         source files and -AA requests that all lines in a source file
 308         are annotated.
 309
 310         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 311
 312         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 313
 314         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 315         so s_lowpc etc. get declared.
 316
 317         * arcs.h (doarcs): created.
 318
 319         * arcs.c: reordered static functions such that they get defined
 320         before use.
 321
 322         * gprof.c (main): added options:
 323            -A: request annotation of all source lines (with -S)
 324            -m: minimum execution count (with default basic-block display)
 325            -N: force new file format (only if BSD_COMPATIBLE is defined)
 326            -S: annotate source file
 327            -t: set table length (with -S)
 328
 329         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 330         source.o time_hist.o
 331
 332         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 333
 334         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 335         on the fact being able to store a long in a double without loss of
 336         precision; this does not hold on machines with 64 bit longs and 64
 337         bit doubles.
 338
 339 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 340
 341         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 342         greater than 0.0.  Suggested by Harold Assink
 343         <carlo@sg.tn.tudelft.nl>.
 344
 345 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 346
 347         * printgprof.c (printprof): Use free, not cfree.
 348         (printgprof, printindex): Ditto.
 349
 350 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 351
 352         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 353         decls extern to keep native HP compiler quiet.
 354
 355 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)

 513
 514 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 515
 516         * gprof.1: updated SYNOPSIS to match actual behavior.
 517
 518 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 519
 520         * gen-c-prog.awk:  New awk script, lightly changed from
 521         previously deleted make-c-prog.awk.  Converts a text file
 522         to a c function that prints that text.
 523         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 524         Inputs to gen-c-prog.awk, containing text describing
 525         gprof output.
 526         * blurbs.c:  Removed.  Use *_bl.c instead.
 527         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 528         from *_bl.m files.  Also, improve *clean rules.
 529         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 530
 531
 532 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 533
 534         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 535         output styles:  The default is similar to the old FSF gprof,
 536         while -T sets the variable bsd_style_output, which causes
 537         output matching Berkeley's gprof.  The biggest differences
 538         are that with the FSF style output, the flat profile comes
 539         before the call graph; numbers come before explanations;
 540         and there is less gratuitous white space.
 541         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 542         variable causes discarding of initial underscores when
 543         printing symbol names.  It is set unless there is a "main"
 544         symbol (without an underscore).
 545         * printfgprof.c:  New function printnameonly(), called
 546         by printname().  It handles stripping of initial '_',
 547         as well as C++ name-demangling.
 548         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 549         It is just as convenient to edit blurbs.c directly.
 550         * Makefile.in:  Removed rule for making blurbs.c.
 551         * blurbs.c:  This is now a true source file (as opposed
 552         to being generated from gprof.callg and gprof.flat).
 553         Change style to use one long string literal, instead of
 554         one literal per output line.  Add FSF-style blurb for call graph.
 555
 556 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 557
 558         * Makefile.in: always create installation directories.

 560 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)

 567         call.{flag,callg} files.
 568
 569         * gprof.1: now uses the standard man macros instead of the new BSD
 570         mandoc macros.
 571
 572 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 573
 574         * configure.in:  Remove host section, expand target section.
 575         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 576         * config/tmake-*:  Remove leftover crud.
 577
 578         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 579         * make-c-prog.awk:  which processes text files into C programs.
 580         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 581         to print blurbs.
 582         (printblurb):  Remove.
 583         * Makefile.in:  Infrastructure to build blurbs.
 584         * pathnames.h:  has been removed.  Gprof now has no filename
 585         dependencies in it.
 586         * gprof.c:  Lint.
 587

 595
 596 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 597
 598         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 599         help in debugging the problem (with -DDEBUG)
 600         * gprof.c: symbol values are now real values, don't add the vma
 601         anymore. (done for solaris; should verify this on other platforms)
 602         * ChangeLog: created.
