gprof/ChangeLog

   1 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
   2
   3         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
   4         binutils release.
   5
   6 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
   7
   8         * symtab.c (symtab_finalize): ensure globals symbols really
   9         are favored over static ones---even if their name looks less
  10         preferable; this is important for HP-UX; for example, there
  11         is a static label Ltext_something that aliases the global
  12         symbol _start
  13
  14         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
  15         output only; also, auto-scaling is now performed based on
  16         per-call, rather than total execution time, which is what it was
  17         meant to be.
  18
  19         * gprof.h (File_Format): new type.
  20
  21         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
  22         sync with Cygnus version numbers though...
  23
  24         (long_options): renamed --gmon-info to --file-info, --width added,
  25         renamed --old-file-format to --file-format
  26         (main): dito; also added support to read prof files, but as
  27         mon_out_read() is not implemented, it's #ifdef'd out for now
  28
  29         (usage): update to reflect new options.
  30
  31         * gmon_io.c: replaced "old_file_format" by more general
  32         "file_format" option
  33
  34         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
  35
  36         * core.c (core_sym_class): added back check for __gnu_compiled and
  37         ___gnu_compiled for the benefit of systems without
  38         bfd_find_nearest_line() support
  39
  40         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
  41         with section-relative addresses
  42
  43         (core_create_function_syms): get_src_info() calls are currently
  44         enabled for OSF/1 only.  It appears to work allright for SunOS
  45         4.1.x as well, but on SPARCs it gets painfully slow with the
  46         current implementation of aout_32_find_nearest_line();
  47         unfortunately, this means that static functions will not have their
  48         filename printed in the call-graph function index; line-level
  49         profiling should still work, but requires some patience
  50
  51         * cg_print.c (cg_print_index): sanitized printing of index when
  52         using FSF-style output; in particular, output width is now controlled
  53         via option --width and the function tries hard to keep columns
  54         aligned even in the presence of (occasional) long names
  55
  56         * NOTES: a first shot at updating the documentation.
  57
  58 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  59
  60         * core.c (core_create_function_syms): fixed computation of min_vma
  61         and max_vma.
  62
  63         * *.c: removed rcsid.
  64
  65 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  66
  67         * Lots of changes from David Mosberger-Tang:
  68
  69         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
  70
  71         * gprof.c (main): put parentheses around & within &&.
  72
  73         * basic_blocks.c (bb_read_rec): print warning message (once) when
  74         ignoring basic-block execution counts.
  75
  76         * source.c (source_file_lookup_name): corrected second argument to
  77         strcmp().
  78
  79         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
  80         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
  81
  82         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
  83         supported both for old and new (versioned) gmon.out files.  Old
  84         files are identified as version 0.
  85
  86         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
  87         long (instead of 4) because that is what OSF/1 v3.0 uses.
  88
  89         * core.c: minor fixes and debugging info changes.
  90
  91         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
  92
  93         * core.c (core_init): if .text cannot be found, try $CODE$ (the
  94         name of the text-section under HP-UX).
  95
  96         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
  97         points one past the last sampling bin, so hist_scale should be
  98         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
  99         hist_num_bins - 1".
 100
 101         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 102         hist_num_bins.
 103
 104         * configure.in: added alpha-*-*) for per-target config.
 105
 106         * alpha.c, alpha.h: created.
 107
 108         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 109
 110         * core.c (core_create_function_syms, core_create_line_syms):
 111         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 112         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 113         addr) continues to guarantee not to return 0 on any address.  It
 114         also avoids incorrectly crediting the first/last symbol in the
 115         text-space.
 116
 117         * core.c (core_create_line_syms): always create function symbols
 118         first, then merge in line symbols; this is so that if parts of the
 119         program were compiled without -g, function-level symbols are
 120         available still.
 121
 122         * utils.c (print_name_only): support for print_path added.
 123
 124         * symtab.c (cmp_addr): also use is_func flag in comparison.
 125         (symtab_finalize): return immediately when table empty; now
 126         more careful about getting rid of the right duplicate symbol.
 127
 128         * sparc.c (find_call): many fixes---this function was rather
 129         botched in binutils-2.4 already; it should work again.
 130
 131         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 132         not good to rely on get_src_info() to return distinct string
 133         pointers).
 134
 135         * search_list.c (search_list_append): added cast for xmalloc().
 136
 137         * hist.c: added explicit initialization to some of the global
 138         variables; fixed SItab (scales were off by a factor of 10).
 139
 140         * hist.h: include of bfd.h added.
 141
 142         * gprof.c, gprof.h (print_path): added.
 143
 144         * gprof.h (MAX): fixed.
 145
 146         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 147
 148         * gmon_io.c: added some casts to (long) so we can always print as %lx
 149
 150         * core.c (core_get_text_space): fixed to make it work.
 151
 152         * cg_print.c (cg_print_index): added support for print_path option.
 153
 154         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 155
 156         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 157         as some compilers complain (e.g., DEC's OSF/1 compiler)
 158
 159         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 160         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 161
 162         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 163
 164         * gprof.c: added "_mcount" to default_excluded_list.
 165         (main): if output_style==0 and there is either a histogram or a
 166         call-graph, always generate flat and call-graph, no matter what
 167         line_granularity is set to.
 168
 169         * source.c (source_file_lookup_name): if searching for sf->name
 170         fails, try again with filename obtained after stripping off any
 171         partial path from sf->name.
 172
 173         * gprof.h (SRCDEBUG): added.
 174
 175         * search_list.c (search_list_append): directories were added in wrong
 176         order.
 177
 178         * reimplemented selection mechanism from ground up; it is now possible
 179         to accurately control what gets included/excluded in each of the
 180         output styles;  a "symbol-specification" (spec) is the basic means
 181         to select a set of symbols; a spec has the syntax:
 182
 183           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 184           arc == spec/spec.
 185
 186         any of the terminal symbols can be empty, in which case they
 187         match anything (wildcards).  NAME is interpreted as a FILENAME
 188         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 189         with a digit, and as FUNCNAME otherwise.
 190
 191         For example, to get a call-graph display that ignores arcs
 192         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 193         show only arcs into bar() (no matter what the caller),
 194         you'd say "--graph=/bar"; and to get a call-graph without
 195         any arc info, you'd say "--graph=/";  similarly, to
 196         get a flat profile without mcount, you'd say "--no-flat=mcount"
 197         and to get a flat profile that shows includes all functions
 198         you'd say "--flat=""" (i.e., an empty spec)
 199
 200         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 201
 202         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 203
 204         * gmon_out.h: all headers now declared in terms of characters
 205           to avoid getting into trouble with different compilers introducing
 206           different amount of padding; the code already accessed the fields
 207           through bfd functions, so that didn't have to change.
 208
 209         * hist.c (hist_read_rec, hist_write_rec): added support for
 210           collection pc histograms measuring quantities other than time;
 211           the histogram header now includes a field that specifies the
 212           dimension of the quantity measured by the histogram bins
 213           (normally, this is "seconds", but other meaningful dimensions
 214            include such things as "I-cache misses", "instruction issue stalls"
 215            etc.); there is also a field to specify a one-character
 216           abbreviation for the dimension; in the case of time, this would
 217           be 's'; in most other cases it probably would be '1' (not a physical
 218           dimension).
 219
 220         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 221
 222         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 223           has become old_file_version; gmon_io.c now always supports old-style
 224           gmon.out files; it first tries to read gmon.out as a new version
 225           file, if that fails, it tries to read it in the old format;
 226           although not very likely, it is possible for gprof to mistake an
 227           old-style file as a new one (the first 4 bytes would have to
 228           be "gmon"---including the trailing '\0'); in that case, it is
 229           necessary to specify --old-file-version
 230
 231         * gprof.h: removed dependency on SYSV; the code now always uses
 232           strrchr(), memset(), and memcpy() and does not include either
 233           of string.h or strings.h; this should make gprof compile on
 234           any (Unix) system without configuration (per suggestion of
 235           raeburn@cygnus.com)
 236
 237         * gprof.c (usage): fixed location of --new-file-format option.
 238
 239         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 240
 241         * flat_bl.m: removed formfeed at end of file; the form-feed
 242           is now printed cg_print.c only when necessary.
 243
 244         * major rewrite of gprof---too many changes to mention all of
 245           them.  new features:
 246
 247         + -l now requests profiling at the line level (as opposed
 248           to function level); in this mode, gprof creates a "symbol"
 249           (aka name-list entry) for each line of source code, instead
 250            of one per function)
 251
 252         + support for a new gmon.out file format; the new format
 253           consists of a header with a magic and a version number,
 254           followed by a sequence of profile data; profile data
 255           can any of: (a) PC histogram, (b) call-graph arcs, or
 256           (c) basic-block execution counts; the version number makes
 257           it possible to extend gmon.out in a backwards compatible
 258           fashion
 259
 260         + support for tcov style annotated output: if the gmon.out file
 261           contains basic-block execution counts, the user can request
 262           the generation of annotated source files, much like Sun's
 263           tcov used to do
 264
 265         + long options
 266
 267         + new scheme to suppress symbols that aren't function names
 268           (e.g., avoids mistaking a goto label as a function)
 269
 270         + reorganized source code to make it more managable; as a
 271           side effect, gprof now compiles cleanly with "gcc -Wall"
 272
 273         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 274
 275         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 276         final cross-check to determine whether a static symbol should be
 277         considered as a function-name.
 278
 279         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 280
 281         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 282         stdin; this is useful if you wanna keep gmon.out files compressed;
 283         this way you can "gzcat" the compressed file into gprof.
 284
 285         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 286
 287         * basic_blocks.c (bb_annotate_source): added support for creating
 288         .tcov files when option flag_annotate_make_files is TRUE.
 289         (annotate_with_count): all counts less than the minimum count
 290         specified by -m are now annotated with hash-marks.
 291
 292         * gprof.c (main): -A is now followed by a string of option chars.
 293
 294         * basic_blocks.c (annotate_with_count): replaced b->count with
 295         cnt.
 296
 297         * source.c: flag_annotate_source replaced by source_lock_map.
 298
 299         * source.h: source_lock_map added.
 300
 301         * gprof.c (main): new command-line syntax: -S simply specifies
 302         which source-files user is interested in; -A requests annotated
 303         source files and -AA requests that all lines in a source file
 304         are annotated.
 305
 306         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 307
 308         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 309
 310         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 311         so s_lowpc etc. get declared.
 312
 313         * arcs.h (doarcs): created.
 314
 315         * arcs.c: reordered static functions such that they get defined
 316         before use.
 317
 318         * gprof.c (main): added options:
 319            -A: request annotation of all source lines (with -S)
 320            -m: minimum execution count (with default basic-block display)
 321            -N: force new file format (only if BSD_COMPATIBLE is defined)
 322            -S: annotate source file
 323            -t: set table length (with -S)
 324
 325         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 326         source.o time_hist.o
 327
 328         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 329
 330         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 331         on the fact being able to store a long in a double without loss of
 332         precision; this does not hold on machines with 64 bit longs and 64
 333         bit doubles.
 334
 335 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 336
 337         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 338         greater than 0.0.  Suggested by Harold Assink
 339         <carlo@sg.tn.tudelft.nl>.
 340
 341 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 342
 343         * printgprof.c (printprof): Use free, not cfree.
 344         (printgprof, printindex): Ditto.
 345
 346 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 347
 348         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 349         decls extern to keep native HP compiler quiet.
 350
 351 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 352
 353         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 354         __gnu_compiled, for the benefit of systems which add a leading
 355         underscore.
 356

 511
 512         * gprof.1: updated SYNOPSIS to match actual behavior.
 513
 514 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 515
 516         * gen-c-prog.awk:  New awk script, lightly changed from
 517         previously deleted make-c-prog.awk.  Converts a text file
 518         to a c function that prints that text.
 519         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 520         Inputs to gen-c-prog.awk, containing text describing
 521         gprof output.
 522         * blurbs.c:  Removed.  Use *_bl.c instead.
 523         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 524         from *_bl.m files.  Also, improve *clean rules.
 525         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 526
 527
 528 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 529
 530         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 531         output styles:  The default is similar to the old FSF gprof,
 532         while -T sets the variable bsd_style_output, which causes
 533         output matching Berkeley's gprof.  The biggest differences
 534         are that with the FSF style output, the flat profile comes
 535         before the call graph; numbers come before explanations;
 536         and there is less gratuitous white space.
 537         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 538         variable causes discarding of initial underscores when
 539         printing symbol names.  It is set unless there is a "main"
 540         symbol (without an underscore).
 541         * printfgprof.c:  New function printnameonly(), called
 542         by printname().  It handles stripping of initial '_',
 543         as well as C++ name-demangling.
 544         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 545         It is just as convenient to edit blurbs.c directly.
 546         * Makefile.in:  Removed rule for making blurbs.c.
 547         * blurbs.c:  This is now a true source file (as opposed
 548         to being generated from gprof.callg and gprof.flat).
 549         Change style to use one long string literal, instead of
 550         one literal per output line.  Add FSF-style blurb for call graph.
 551
 552 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 553
 554         * Makefile.in: always create installation directories.
 555
 556 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 557
 558         * Makefile.in: change ${MACHINE} to $(MACHINE).

 561
 562         * Makefile.in:  removed installation of the now useless
 563         call.{flag,callg} files.
 564
 565         * gprof.1: now uses the standard man macros instead of the new BSD
 566         mandoc macros.
 567
 568 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 569
 570         * configure.in:  Remove host section, expand target section.
 571         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 572         * config/tmake-*:  Remove leftover crud.
 573
 574         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 575         * make-c-prog.awk:  which processes text files into C programs.
 576         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 577         to print blurbs.
 578         (printblurb):  Remove.
 579         * Makefile.in:  Infrastructure to build blurbs.
 580         * pathnames.h:  has been removed.  Gprof now has no filename
 581         dependencies in it.
 582         * gprof.c:  Lint.
 583

 591
 592 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 593
 594         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 595         help in debugging the problem (with -DDEBUG)
 596         * gprof.c: symbol values are now real values, don't add the vma
 597         anymore. (done for solaris; should verify this on other platforms)
 598         * ChangeLog: created.
