   2
   3         * configure.in: Don't set CC.  Look for --enable-shared.  Set
   4         BFDLIB and HLDFLAGS and substitute them.
   5         * configure: Rebuild.
   6         * Makefile.in (LIBS): Use @BFDLIB@.
   7         (HLDFLAGS): New variable.
   8         (gprof): Use $(HLDFLAGS).

  10 Mon Feb  5 16:34:44 1996  Ian Lance Taylor  <ian@cygnus.com>
  11
  12         Support for building bfd and opcodes as shared libraries, based on

  48
  49 Sun Dec 24 21:32:27 1995  Jeffrey A Law  (law@cygnus.com)
  50
  51         * core.c (core_sym_class): Ignore symbols without BSF_FUNCTION
  52         set if ignore_non_function is set.

  60
  61         * Makefile.in (.m.c): Strip out directory name from function
  62         name.
  63
  64         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
  65         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
  66         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
  67
  68         * vax.c: Don't include vax.h here.
  69
  70 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

  82 Wed Nov  1 12:51:21 1995  Per Bothner  <bothner@kalessin.cygnus.com>
  83
  84         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
  85         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
  86         on info).
  87
  88 Wed Nov  1 15:23:15 1995  Manfred Hollstein KS/EF4A 60/1F/110 #40283  <manfred@lts.sel.alcatel.de>

  95         (mostlyclean):  Don't remove gprof.info*.

  99
 100         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 101
 102         * Makefile.in: Add dependecies for $(OBJS) on header files.
 103
 104         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 105         style output format to make it consistent.
 106         * dummy.c (find_call): Fix typo in error message.
 107
 108 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 109
 110         * Makefile.in (maintainer-clean): New target, synonym for
 111         realclean.
 112
 113 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 114
 115         * Makefile.in (install): Don't install in $(tooldir).

 117 Fri Aug 25 15:30:05 1995  Ken Raeburn  <raeburn@cygnus.com>
 118
 119         NS32K changes from Ian Dall:
 120         * configure.in: Use ns32k, not ns532.
 121         * ns532.c: Include symtab.h.
 122         (find_call): Renamed from findcall.  Print a message.
 123         * ns532.h: Remove dummy.h comments.
 124
 125 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 126
 127         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 128         that we're using autoconf.
 129
 130 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 131
 132         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
 133         to proper type of "unsigned int *".
 134
 135 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 136
 137         * configure.in: Use changequote around use of [].
 138
 139 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 140
 141         * Makefile.in (distclean, realclean): Remove config.cache and
 142           config.log.
 143
 144 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 145
 146         * Makefile.in (Makefile): Added config.status to dependency list.
 147           (config.status): New target.
 148           (SHELL): New definition.
 149
 150 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 151
 152         * Makefile.in (install): Depend on "all".
 153
 154 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 155
 156         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 157         to match configure script.
 158
 159 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 160
 161         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 162           comment emitted by this script to gen-c-prog.awk.
 163
 164         * Makefile.in, configure.in: Converted to use autoconf.
 165         * configure: New file, generated with autoconf 2.3.
 166         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 167           mt-tahoe, mt-vax}: Removed.
 168
 169 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 170
 171         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 172
 173         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 174
 175         * All *.c: More cleanup towards GNU format.
 176
 177         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 178         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 179         that bfd_vma is only guaranteed to be at least as big as a pointer.
 180
 181         (GMON_Record_tag): added explicit enumeration values to ensure
 182         compatibility across compilers.
 183
 184         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 185         sizeof(char*).
 186
 187 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 188
 189         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 190         of constructs GNU indent couldn't handle.  Block comments not yet
 191         rewritten in GNU format.
 192
 193         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 194         binutils release.
 195
 196 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 197
 198         * symtab.c (symtab_finalize): ensure globals symbols really
 199         are favored over static ones---even if their name looks less
 200         preferable; this is important for HP-UX; for example, there
 201         is a static label Ltext_something that aliases the global
 202         symbol _start
 203
 204         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 205         output only; also, auto-scaling is now performed based on
 206         per-call, rather than total execution time, which is what it was
 207         meant to be.
 208
 209         * gprof.h (File_Format): new type.
 210
 211         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 212         sync with Cygnus version numbers though...
 213
 214         (long_options): renamed --gmon-info to --file-info, --width added,
 215         renamed --old-file-format to --file-format
 216         (main): dito; also added support to read prof files, but as
 217         mon_out_read() is not implemented, it's #ifdef'd out for now
 218
 219         (usage): update to reflect new options.
 220
 221         * gmon_io.c: replaced "old_file_format" by more general
 222         "file_format" option
 223
 224         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 225
 226         * core.c (core_sym_class): added back check for __gnu_compiled and
 227         ___gnu_compiled for the benefit of systems without
 228         bfd_find_nearest_line() support
 229
 230         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 231         with section-relative addresses
 232
 233         (core_create_function_syms): get_src_info() calls are currently
 234         enabled for OSF/1 only.  It appears to work allright for SunOS
 235         4.1.x as well, but on SPARCs it gets painfully slow with the
 236         current implementation of aout_32_find_nearest_line();
 237         unfortunately, this means that static functions will not have their
 238         filename printed in the call-graph function index; line-level
 239         profiling should still work, but requires some patience
 240
 241         * cg_print.c (cg_print_index): sanitized printing of index when
 242         using FSF-style output; in particular, output width is now controlled
 243         via option --width and the function tries hard to keep columns
 244         aligned even in the presence of (occasional) long names
 245
 246         * NOTES: a first shot at updating the documentation.
 247
 248 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 249
 250         * core.c (core_create_function_syms): fixed computation of min_vma
 251         and max_vma.
 252
 253         * *.c: removed rcsid.
 254
 255 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 256
 257         * Lots of changes from David Mosberger-Tang:
 258
 259         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 260
 261         * gprof.c (main): put parentheses around & within &&.
 262
 263         * basic_blocks.c (bb_read_rec): print warning message (once) when
 264         ignoring basic-block execution counts.
 265
 266         * source.c (source_file_lookup_name): corrected second argument to
 267         strcmp().
 268
 269         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 270         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 271
 272         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 273         supported both for old and new (versioned) gmon.out files.  Old
 274         files are identified as version 0.
 275
 276         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 277         long (instead of 4) because that is what OSF/1 v3.0 uses.
 278
 279         * core.c: minor fixes and debugging info changes.
 280
 281         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 282
 283         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 284         name of the text-section under HP-UX).
 285
 286         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 287         points one past the last sampling bin, so hist_scale should be
 288         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 289         hist_num_bins - 1".
 290
 291         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 292         hist_num_bins.
 293
 294         * configure.in: added alpha-*-*) for per-target config.
 295
 296         * alpha.c, alpha.h: created.
 297
 298         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 299
 300         * core.c (core_create_function_syms, core_create_line_syms):
 301         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 302         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 303         addr) continues to guarantee not to return 0 on any address.  It
 304         also avoids incorrectly crediting the first/last symbol in the
 305         text-space.
 306
 307         * core.c (core_create_line_syms): always create function symbols
 308         first, then merge in line symbols; this is so that if parts of the
 309         program were compiled without -g, function-level symbols are
 310         available still.
 311
 312         * utils.c (print_name_only): support for print_path added.
 313
 314         * symtab.c (cmp_addr): also use is_func flag in comparison.
 315         (symtab_finalize): return immediately when table empty; now
 316         more careful about getting rid of the right duplicate symbol.
 317
 318         * sparc.c (find_call): many fixes---this function was rather
 319         botched in binutils-2.4 already; it should work again.
 320
 321         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 322         not good to rely on get_src_info() to return distinct string
 323         pointers).
 324
 325         * search_list.c (search_list_append): added cast for xmalloc().
 326
 327         * hist.c: added explicit initialization to some of the global
 328         variables; fixed SItab (scales were off by a factor of 10).
 329
 330         * hist.h: include of bfd.h added.
 331
 332         * gprof.c, gprof.h (print_path): added.
 333
 334         * gprof.h (MAX): fixed.
 335
 336         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 337
 338         * gmon_io.c: added some casts to (long) so we can always print as %lx
 339
 340         * core.c (core_get_text_space): fixed to make it work.
 341
 342         * cg_print.c (cg_print_index): added support for print_path option.
 343
 344         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 345
 346         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 347         as some compilers complain (e.g., DEC's OSF/1 compiler)
 348
 349         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 350         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 351
 352         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 353
 354         * gprof.c: added "_mcount" to default_excluded_list.
 355         (main): if output_style==0 and there is either a histogram or a
 356         call-graph, always generate flat and call-graph, no matter what
 357         line_granularity is set to.
 358
 359         * source.c (source_file_lookup_name): if searching for sf->name
 360         fails, try again with filename obtained after stripping off any
 361         partial path from sf->name.
 362
 363         * gprof.h (SRCDEBUG): added.
 364
 365         * search_list.c (search_list_append): directories were added in wrong
 366         order.
 367
 368         * reimplemented selection mechanism from ground up; it is now possible
 369         to accurately control what gets included/excluded in each of the
 370         output styles;  a "symbol-specification" (spec) is the basic means
 371         to select a set of symbols; a spec has the syntax:
 372
 373           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 374           arc == spec/spec.
 375
 376         any of the terminal symbols can be empty, in which case they
 377         match anything (wildcards).  NAME is interpreted as a FILENAME
 378         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 379         with a digit, and as FUNCNAME otherwise.
 380
 381         For example, to get a call-graph display that ignores arcs
 382         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 383         show only arcs into bar() (no matter what the caller),
 384         you'd say "--graph=/bar"; and to get a call-graph without
 385         any arc info, you'd say "--graph=/";  similarly, to
 386         get a flat profile without mcount, you'd say "--no-flat=mcount"
 387         and to get a flat profile that shows includes all functions
 388         you'd say "--flat=""" (i.e., an empty spec)
 389
 390         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 391
 392         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 393
 394         * gmon_out.h: all headers now declared in terms of characters
 395           to avoid getting into trouble with different compilers introducing
 396           different amount of padding; the code already accessed the fields
 397           through bfd functions, so that didn't have to change.
 398
 399         * hist.c (hist_read_rec, hist_write_rec): added support for
 400           collection pc histograms measuring quantities other than time;
 401           the histogram header now includes a field that specifies the
 402           dimension of the quantity measured by the histogram bins
 403           (normally, this is "seconds", but other meaningful dimensions
 404            include such things as "I-cache misses", "instruction issue stalls"
 405            etc.); there is also a field to specify a one-character
 406           abbreviation for the dimension; in the case of time, this would
 407           be 's'; in most other cases it probably would be '1' (not a physical
 408           dimension).
 409
 410         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 411
 412         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 413           has become old_file_version; gmon_io.c now always supports old-style
 414           gmon.out files; it first tries to read gmon.out as a new version
 415           file, if that fails, it tries to read it in the old format;
 416           although not very likely, it is possible for gprof to mistake an
 417           old-style file as a new one (the first 4 bytes would have to
 418           be "gmon"---including the trailing '\0'); in that case, it is
 419           necessary to specify --old-file-version
 420
 421         * gprof.h: removed dependency on SYSV; the code now always uses
 422           strrchr(), memset(), and memcpy() and does not include either
 423           of string.h or strings.h; this should make gprof compile on
 424           any (Unix) system without configuration (per suggestion of
 425           raeburn@cygnus.com)
 426
 427         * gprof.c (usage): fixed location of --new-file-format option.
 428
 429         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 430
 431         * flat_bl.m: removed formfeed at end of file; the form-feed
 432           is now printed cg_print.c only when necessary.
 433
 434         * major rewrite of gprof---too many changes to mention all of
 435           them.  new features:
 436
 437         + -l now requests profiling at the line level (as opposed
 438           to function level); in this mode, gprof creates a "symbol"
 439           (aka name-list entry) for each line of source code, instead
 440            of one per function)
 441
 442         + support for a new gmon.out file format; the new format
 443           consists of a header with a magic and a version number,
 444           followed by a sequence of profile data; profile data
 445           can any of: (a) PC histogram, (b) call-graph arcs, or
 446           (c) basic-block execution counts; the version number makes
 447           it possible to extend gmon.out in a backwards compatible
 448           fashion
 449
 450         + support for tcov style annotated output: if the gmon.out file
 451           contains basic-block execution counts, the user can request
 452           the generation of annotated source files, much like Sun's
 453           tcov used to do
 454
 455         + long options
 456
 457         + new scheme to suppress symbols that aren't function names
 458           (e.g., avoids mistaking a goto label as a function)
 459
 460         + reorganized source code to make it more managable; as a
 461           side effect, gprof now compiles cleanly with "gcc -Wall"
 462
 463         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 464
 465         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 466         final cross-check to determine whether a static symbol should be
 467         considered as a function-name.
 468
 469         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 470
 471         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 472         stdin; this is useful if you wanna keep gmon.out files compressed;
 473         this way you can "gzcat" the compressed file into gprof.
 474
 475         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 476
 477         * basic_blocks.c (bb_annotate_source): added support for creating
 478         .tcov files when option flag_annotate_make_files is TRUE.
 479         (annotate_with_count): all counts less than the minimum count
 480         specified by -m are now annotated with hash-marks.
 481
 482         * gprof.c (main): -A is now followed by a string of option chars.
 483
 484         * basic_blocks.c (annotate_with_count): replaced b->count with
 485         cnt.
 486
 487         * source.c: flag_annotate_source replaced by source_lock_map.
 488
 489         * source.h: source_lock_map added.
 490
 491         * gprof.c (main): new command-line syntax: -S simply specifies
 492         which source-files user is interested in; -A requests annotated
 493         source files and -AA requests that all lines in a source file
 494         are annotated.
 495
 496         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 497
 498         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 499
 500         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 501         so s_lowpc etc. get declared.
 502
 503         * arcs.h (doarcs): created.
 504
 505         * arcs.c: reordered static functions such that they get defined
 506         before use.
 507
 508         * gprof.c (main): added options:
 509            -A: request annotation of all source lines (with -S)
 510            -m: minimum execution count (with default basic-block display)
 511            -N: force new file format (only if BSD_COMPATIBLE is defined)
 512            -S: annotate source file
 513            -t: set table length (with -S)
 514
 515         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 516         source.o time_hist.o
 517

 519
 520         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 521         on the fact being able to store a long in a double without loss of
 522         precision; this does not hold on machines with 64 bit longs and 64
 523         bit doubles.

 720         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 721         output styles:  The default is similar to the old FSF gprof,
 722         while -T sets the variable bsd_style_output, which causes
 723         output matching Berkeley's gprof.  The biggest differences
 724         are that with the FSF style output, the flat profile comes
 725         before the call graph; numbers come before explanations;
 726         and there is less gratuitous white space.
 727         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 728         variable causes discarding of initial underscores when
 729         printing symbol names.  It is set unless there is a "main"
 730         symbol (without an underscore).
 731         * printfgprof.c:  New function printnameonly(), called
 732         by printname().  It handles stripping of initial '_',
 733         as well as C++ name-demangling.
 734         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 735         It is just as convenient to edit blurbs.c directly.
 736         * Makefile.in:  Removed rule for making blurbs.c.
 737         * blurbs.c:  This is now a true source file (as opposed
 738         to being generated from gprof.callg and gprof.flat).
 739         Change style to use one long string literal, instead of
 740         one literal per output line.  Add FSF-style blurb for call graph.

 743
 744         * Makefile.in: always create installation directories.
 745
 746 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 747
 748         * Makefile.in: change ${MACHINE} to $(MACHINE).

 751
 752         * Makefile.in:  removed installation of the now useless
 753         call.{flag,callg} files.
 754
 755         * gprof.1: now uses the standard man macros instead of the new BSD
 756         mandoc macros.
 757
 758 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 759
 760         * configure.in:  Remove host section, expand target section.
 761         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 762         * config/tmake-*:  Remove leftover crud.
 763
 764         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 765         * make-c-prog.awk:  which processes text files into C programs.
 766         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 767         to print blurbs.
 768         (printblurb):  Remove.
 769         * Makefile.in:  Infrastructure to build blurbs.
 770         * pathnames.h:  has been removed.  Gprof now has no filename
 771         dependencies in it.
 772         * gprof.c:  Lint.

 775
 776         * Makefile.in: define man1dir and install the man page

 779
 780         * Makefile.in: added dummy info and install-info targets
 781
 782 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 783
 784         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 785         help in debugging the problem (with -DDEBUG)
 786         * gprof.c: symbol values are now real values, don't add the vma
 787         anymore. (done for solaris; should verify this on other platforms)
 788         * ChangeLog: created.
