   1 Thu Mar 21 17:02:02 1996  David Mosberger-Tang  <davidm@azstarnet.com>
   2
   3         * gprof.c (default_excluded_list): Add "__mcount".
   4
   5         * gprof.c (main): Change ifdef __osf__ to __alpha__.
   6
   7         * gmon_io.c (gmon_out_read): If BSD44_FORMAT is defined, get the
   8         profiling rate from the header.
   9
  10         * gmon.h (struct raw_phdr): Only include pad if both __alpha__ and
  11         __osf__ are defined.  Add new fields if BSD44_FORMAT is defined.
  12
  13         * alpha.h (MIN_INSN_SIZE): Define.
  14         * core.c (MIN_INSN_SIZE): If not defined, define as 1.
  15         (core_sym_class): Ignore debugging symbols.

  45         * Makefile.in (LIBS): Use @BFDLIB@.
  46         (HLDFLAGS): New variable.

  51         Support for building bfd and opcodes as shared libraries, based on
  52         patches from Alan Modra <alan@spri.levels.unisa.edu.au>:
  53         * Makefile.in (LIBDEPS): New variable.
  54         (LIBS): Use -L../bfd -lbfd.

  77         mappings.
  78         * symtab.h (struct sym): New fields "mapped", "has_been_placed",
  79         "nuses", "prev".
  80         * cg_print.c (cmp_arc_count): New function for sorting arcs.
  81         (cmp_fun_nuses): Likewise for functions.

  89
  90         * core.c (core_sym_class): Ignore symbols without BSF_FUNCTION
  91         set if ignore_non_function is set.

  99
 100         * Makefile.in (.m.c): Strip out directory name from function
 101         name.
 102
 103         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 104         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 105         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 106
 107         * vax.c: Don't include vax.h here.
 108
 109 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

 120
 121 Wed Nov  1 12:51:21 1995  Per Bothner  <bothner@kalessin.cygnus.com>
 122
 123         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 124         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 125         on info).
 126
 127 Wed Nov  1 15:23:15 1995  Manfred Hollstein KS/EF4A 60/1F/110 #40283  <manfred@lts.sel.alcatel.de>
 128

 130
 131 Wed Oct 25 13:24:31 1995  Per Bothner  <bothner@kalessin.cygnus.com>
 132
 133         * Makefile.in (diststuff):  Also make info.
 134         (mostlyclean):  Don't remove gprof.info*.
 135         (maintainer-clean realclean):  Also remove *.info*.
 136
 137 Fri Oct  6 16:25:32 1995  Ken Raeburn  <raeburn@cygnus.com>
 138
 139         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 140
 141         * Makefile.in: Add dependecies for $(OBJS) on header files.
 142
 143         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 144         style output format to make it consistent.
 145         * dummy.c (find_call): Fix typo in error message.
 146
 147 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 148
 149         * Makefile.in (maintainer-clean): New target, synonym for
 150         realclean.
 151
 152 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 153
 154         * Makefile.in (install): Don't install in $(tooldir).
 155
 156 Fri Aug 25 15:30:05 1995  Ken Raeburn  <raeburn@cygnus.com>
 157
 158         NS32K changes from Ian Dall:
 159         * configure.in: Use ns32k, not ns532.
 160         * ns532.c: Include symtab.h.
 161         (find_call): Renamed from findcall.  Print a message.
 162         * ns532.h: Remove dummy.h comments.
 163
 164 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 165
 166         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 167         that we're using autoconf.
 168
 169 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 170
 171         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
 172         to proper type of "unsigned int *".
 173
 174 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 175
 176         * configure.in: Use changequote around use of [].
 177
 178 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 179
 180         * Makefile.in (distclean, realclean): Remove config.cache and
 181           config.log.
 182
 183 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 184
 185         * Makefile.in (Makefile): Added config.status to dependency list.
 186           (config.status): New target.
 187           (SHELL): New definition.
 188
 189 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 190
 191         * Makefile.in (install): Depend on "all".
 192
 193 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 194
 195         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 196         to match configure script.
 197
 198 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 199
 200         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 201           comment emitted by this script to gen-c-prog.awk.
 202
 203         * Makefile.in, configure.in: Converted to use autoconf.
 204         * configure: New file, generated with autoconf 2.3.
 205         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 206           mt-tahoe, mt-vax}: Removed.
 207
 208 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 209
 210         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 211
 212         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 213
 214         * All *.c: More cleanup towards GNU format.
 215
 216         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 217         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 218         that bfd_vma is only guaranteed to be at least as big as a pointer.
 219
 220         (GMON_Record_tag): added explicit enumeration values to ensure
 221         compatibility across compilers.
 222
 223         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 224         sizeof(char*).
 225
 226 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 227
 228         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 229         of constructs GNU indent couldn't handle.  Block comments not yet
 230         rewritten in GNU format.
 231
 232         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 233         binutils release.
 234
 235 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 236
 237         * symtab.c (symtab_finalize): ensure globals symbols really
 238         are favored over static ones---even if their name looks less
 239         preferable; this is important for HP-UX; for example, there
 240         is a static label Ltext_something that aliases the global
 241         symbol _start
 242
 243         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 244         output only; also, auto-scaling is now performed based on
 245         per-call, rather than total execution time, which is what it was
 246         meant to be.
 247
 248         * gprof.h (File_Format): new type.
 249
 250         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 251         sync with Cygnus version numbers though...
 252
 253         (long_options): renamed --gmon-info to --file-info, --width added,
 254         renamed --old-file-format to --file-format
 255         (main): dito; also added support to read prof files, but as
 256         mon_out_read() is not implemented, it's #ifdef'd out for now
 257
 258         (usage): update to reflect new options.
 259
 260         * gmon_io.c: replaced "old_file_format" by more general
 261         "file_format" option
 262
 263         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 264
 265         * core.c (core_sym_class): added back check for __gnu_compiled and
 266         ___gnu_compiled for the benefit of systems without
 267         bfd_find_nearest_line() support
 268
 269         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 270         with section-relative addresses
 271
 272         (core_create_function_syms): get_src_info() calls are currently
 273         enabled for OSF/1 only.  It appears to work allright for SunOS
 274         4.1.x as well, but on SPARCs it gets painfully slow with the
 275         current implementation of aout_32_find_nearest_line();
 276         unfortunately, this means that static functions will not have their
 277         filename printed in the call-graph function index; line-level
 278         profiling should still work, but requires some patience
 279
 280         * cg_print.c (cg_print_index): sanitized printing of index when
 281         using FSF-style output; in particular, output width is now controlled
 282         via option --width and the function tries hard to keep columns
 283         aligned even in the presence of (occasional) long names
 284
 285         * NOTES: a first shot at updating the documentation.
 286
 287 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 288
 289         * core.c (core_create_function_syms): fixed computation of min_vma
 290         and max_vma.
 291
 292         * *.c: removed rcsid.
 293
 294 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 295
 296         * Lots of changes from David Mosberger-Tang:
 297
 298         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 299
 300         * gprof.c (main): put parentheses around & within &&.
 301
 302         * basic_blocks.c (bb_read_rec): print warning message (once) when
 303         ignoring basic-block execution counts.
 304
 305         * source.c (source_file_lookup_name): corrected second argument to
 306         strcmp().
 307
 308         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 309         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 310
 311         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 312         supported both for old and new (versioned) gmon.out files.  Old
 313         files are identified as version 0.
 314
 315         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 316         long (instead of 4) because that is what OSF/1 v3.0 uses.
 317
 318         * core.c: minor fixes and debugging info changes.
 319
 320         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 321
 322         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 323         name of the text-section under HP-UX).
 324
 325         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 326         points one past the last sampling bin, so hist_scale should be
 327         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 328         hist_num_bins - 1".
 329
 330         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 331         hist_num_bins.
 332
 333         * configure.in: added alpha-*-*) for per-target config.
 334
 335         * alpha.c, alpha.h: created.
 336
 337         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 338
 339         * core.c (core_create_function_syms, core_create_line_syms):
 340         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 341         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 342         addr) continues to guarantee not to return 0 on any address.  It
 343         also avoids incorrectly crediting the first/last symbol in the
 344         text-space.
 345
 346         * core.c (core_create_line_syms): always create function symbols
 347         first, then merge in line symbols; this is so that if parts of the
 348         program were compiled without -g, function-level symbols are
 349         available still.
 350
 351         * utils.c (print_name_only): support for print_path added.
 352
 353         * symtab.c (cmp_addr): also use is_func flag in comparison.
 354         (symtab_finalize): return immediately when table empty; now
 355         more careful about getting rid of the right duplicate symbol.
 356
 357         * sparc.c (find_call): many fixes---this function was rather
 358         botched in binutils-2.4 already; it should work again.
 359
 360         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 361         not good to rely on get_src_info() to return distinct string
 362         pointers).
 363
 364         * search_list.c (search_list_append): added cast for xmalloc().
 365
 366         * hist.c: added explicit initialization to some of the global
 367         variables; fixed SItab (scales were off by a factor of 10).
 368
 369         * hist.h: include of bfd.h added.
 370
 371         * gprof.c, gprof.h (print_path): added.
 372
 373         * gprof.h (MAX): fixed.
 374
 375         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 376
 377         * gmon_io.c: added some casts to (long) so we can always print as %lx
 378
 379         * core.c (core_get_text_space): fixed to make it work.
 380
 381         * cg_print.c (cg_print_index): added support for print_path option.
 382
 383         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 384
 385         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 386         as some compilers complain (e.g., DEC's OSF/1 compiler)
 387
 388         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 389         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 390
 391         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 392
 393         * gprof.c: added "_mcount" to default_excluded_list.
 394         (main): if output_style==0 and there is either a histogram or a
 395         call-graph, always generate flat and call-graph, no matter what
 396         line_granularity is set to.
 397
 398         * source.c (source_file_lookup_name): if searching for sf->name
 399         fails, try again with filename obtained after stripping off any
 400         partial path from sf->name.
 401
 402         * gprof.h (SRCDEBUG): added.
 403
 404         * search_list.c (search_list_append): directories were added in wrong
 405         order.
 406
 407         * reimplemented selection mechanism from ground up; it is now possible
 408         to accurately control what gets included/excluded in each of the
 409         output styles;  a "symbol-specification" (spec) is the basic means
 410         to select a set of symbols; a spec has the syntax:
 411
 412           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 413           arc == spec/spec.
 414
 415         any of the terminal symbols can be empty, in which case they
 416         match anything (wildcards).  NAME is interpreted as a FILENAME
 417         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 418         with a digit, and as FUNCNAME otherwise.
 419
 420         For example, to get a call-graph display that ignores arcs
 421         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 422         show only arcs into bar() (no matter what the caller),
 423         you'd say "--graph=/bar"; and to get a call-graph without
 424         any arc info, you'd say "--graph=/";  similarly, to
 425         get a flat profile without mcount, you'd say "--no-flat=mcount"
 426         and to get a flat profile that shows includes all functions
 427         you'd say "--flat=""" (i.e., an empty spec)
 428
 429         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 430
 431         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 432
 433         * gmon_out.h: all headers now declared in terms of characters
 434           to avoid getting into trouble with different compilers introducing
 435           different amount of padding; the code already accessed the fields
 436           through bfd functions, so that didn't have to change.
 437
 438         * hist.c (hist_read_rec, hist_write_rec): added support for
 439           collection pc histograms measuring quantities other than time;
 440           the histogram header now includes a field that specifies the
 441           dimension of the quantity measured by the histogram bins
 442           (normally, this is "seconds", but other meaningful dimensions
 443            include such things as "I-cache misses", "instruction issue stalls"
 444            etc.); there is also a field to specify a one-character
 445           abbreviation for the dimension; in the case of time, this would
 446           be 's'; in most other cases it probably would be '1' (not a physical
 447           dimension).
 448
 449         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 450
 451         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 452           has become old_file_version; gmon_io.c now always supports old-style
 453           gmon.out files; it first tries to read gmon.out as a new version
 454           file, if that fails, it tries to read it in the old format;
 455           although not very likely, it is possible for gprof to mistake an
 456           old-style file as a new one (the first 4 bytes would have to
 457           be "gmon"---including the trailing '\0'); in that case, it is
 458           necessary to specify --old-file-version
 459
 460         * gprof.h: removed dependency on SYSV; the code now always uses
 461           strrchr(), memset(), and memcpy() and does not include either
 462           of string.h or strings.h; this should make gprof compile on
 463           any (Unix) system without configuration (per suggestion of
 464           raeburn@cygnus.com)
 465
 466         * gprof.c (usage): fixed location of --new-file-format option.
 467
 468         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 469
 470         * flat_bl.m: removed formfeed at end of file; the form-feed
 471           is now printed cg_print.c only when necessary.
 472
 473         * major rewrite of gprof---too many changes to mention all of
 474           them.  new features:
 475
 476         + -l now requests profiling at the line level (as opposed
 477           to function level); in this mode, gprof creates a "symbol"
 478           (aka name-list entry) for each line of source code, instead
 479            of one per function)
 480
 481         + support for a new gmon.out file format; the new format
 482           consists of a header with a magic and a version number,
 483           followed by a sequence of profile data; profile data
 484           can any of: (a) PC histogram, (b) call-graph arcs, or
 485           (c) basic-block execution counts; the version number makes
 486           it possible to extend gmon.out in a backwards compatible
 487           fashion
 488
 489         + support for tcov style annotated output: if the gmon.out file
 490           contains basic-block execution counts, the user can request
 491           the generation of annotated source files, much like Sun's
 492           tcov used to do
 493
 494         + long options
 495
 496         + new scheme to suppress symbols that aren't function names
 497           (e.g., avoids mistaking a goto label as a function)
 498
 499         + reorganized source code to make it more managable; as a
 500           side effect, gprof now compiles cleanly with "gcc -Wall"
 501
 502         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 503
 504         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 505         final cross-check to determine whether a static symbol should be
 506         considered as a function-name.
 507
 508         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 509
 510         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 511         stdin; this is useful if you wanna keep gmon.out files compressed;
 512         this way you can "gzcat" the compressed file into gprof.
 513
 514         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 515
 516         * basic_blocks.c (bb_annotate_source): added support for creating
 517         .tcov files when option flag_annotate_make_files is TRUE.
 518         (annotate_with_count): all counts less than the minimum count
 519         specified by -m are now annotated with hash-marks.
 520
 521         * gprof.c (main): -A is now followed by a string of option chars.
 522
 523         * basic_blocks.c (annotate_with_count): replaced b->count with
 524         cnt.
 525
 526         * source.c: flag_annotate_source replaced by source_lock_map.
 527
 528         * source.h: source_lock_map added.
 529
 530         * gprof.c (main): new command-line syntax: -S simply specifies
 531         which source-files user is interested in; -A requests annotated
 532         source files and -AA requests that all lines in a source file
 533         are annotated.
 534
 535         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 536
 537         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 538
 539         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 540         so s_lowpc etc. get declared.
 541
 542         * arcs.h (doarcs): created.
 543
 544         * arcs.c: reordered static functions such that they get defined
 545         before use.
 546
 547         * gprof.c (main): added options:
 548            -A: request annotation of all source lines (with -S)
 549            -m: minimum execution count (with default basic-block display)
 550            -N: force new file format (only if BSD_COMPATIBLE is defined)
 551            -S: annotate source file
 552            -t: set table length (with -S)
 553
 554         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 555         source.o time_hist.o
 556
 557         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 558
 559         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 560         on the fact being able to store a long in a double without loss of
 561         precision; this does not hold on machines with 64 bit longs and 64
 562         bit doubles.

 567         greater than 0.0.  Suggested by Harold Assink
 568         <carlo@sg.tn.tudelft.nl>.

 572         * printgprof.c (printprof): Use free, not cfree.
 573         (printgprof, printindex): Ditto.

 575 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 576
 577         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 578         decls extern to keep native HP compiler quiet.
 579
 580 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 581
 582         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 583         __gnu_compiled, for the benefit of systems which add a leading
 584         underscore.

 597         Allows compilation with -Dregister= for debugging.
 598
 599         * configure.in: Add ns532 support.

 636
 637         * gprof.c (getsymtab): Change nosyms to long.  Rename
 638         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
 639         errors from bfd_get_symtab_upper_bound and
 640         bfd_canonicalize_symtab.

 727
 728         * printgprof (xmalloc, xrealloc):  Cast results of malloc
 729         and realloc to PTR.

 741         * gprof.1: updated SYNOPSIS to match actual behavior.
 742
 743 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 744
 745         * gen-c-prog.awk:  New awk script, lightly changed from
 746         previously deleted make-c-prog.awk.  Converts a text file
 747         to a c function that prints that text.
 748         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 749         Inputs to gen-c-prog.awk, containing text describing
 750         gprof output.
 751         * blurbs.c:  Removed.  Use *_bl.c instead.
 752         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 753         from *_bl.m files.  Also, improve *clean rules.
 754         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 758
 759         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 760         output styles:  The default is similar to the old FSF gprof,
 761         while -T sets the variable bsd_style_output, which causes
 762         output matching Berkeley's gprof.  The biggest differences
 763         are that with the FSF style output, the flat profile comes
 764         before the call graph; numbers come before explanations;
 765         and there is less gratuitous white space.
 766         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 767         variable causes discarding of initial underscores when
 768         printing symbol names.  It is set unless there is a "main"
 769         symbol (without an underscore).
 770         * printfgprof.c:  New function printnameonly(), called
 771         by printname().  It handles stripping of initial '_',
 772         as well as C++ name-demangling.
 773         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 774         It is just as convenient to edit blurbs.c directly.
 775         * Makefile.in:  Removed rule for making blurbs.c.
 776         * blurbs.c:  This is now a true source file (as opposed
 777         to being generated from gprof.callg and gprof.flat).
 778         Change style to use one long string literal, instead of
 779         one literal per output line.  Add FSF-style blurb for call graph.
 780
 781 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 782
 783         * Makefile.in: always create installation directories.
 784
 785 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 786
 787         * Makefile.in: change ${MACHINE} to $(MACHINE).

 790
 791         * Makefile.in:  removed installation of the now useless
 792         call.{flag,callg} files.
 793
 794         * gprof.1: now uses the standard man macros instead of the new BSD
 795         mandoc macros.
 796
 797 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 798
 799         * configure.in:  Remove host section, expand target section.
 800         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 801         * config/tmake-*:  Remove leftover crud.
 802
 803         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 804         * make-c-prog.awk:  which processes text files into C programs.
 805         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 806         to print blurbs.
 807         (printblurb):  Remove.
 808         * Makefile.in:  Infrastructure to build blurbs.
 809         * pathnames.h:  has been removed.  Gprof now has no filename
 810         dependencies in it.
 811         * gprof.c:  Lint.

 818
 819         * Makefile.in: added dummy info and install-info targets
 820
 821 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 822
 823         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 824         help in debugging the problem (with -DDEBUG)
 825         * gprof.c: symbol values are now real values, don't add the vma
 826         anymore. (done for solaris; should verify this on other platforms)
 827         * ChangeLog: created.
