  24
  25         * gmon.h (struct raw_phdr): Only include pad if both __alpha__ and

  56
  57         * configure.in: Don't set CC.  Look for --enable-shared.  Set
  58         BFDLIB and HLDFLAGS and substitute them.

  94         "nuses", "prev".
  95         * cg_print.c (cmp_arc_count): New function for sorting arcs.
  96         (cmp_fun_nuses): Likewise for functions.

 114
 115         * Makefile.in (.m.c): Strip out directory name from function
 116         name.
 117
 118         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 119         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 120         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 121
 122         * vax.c: Don't include vax.h here.
 123
 124 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

 136 Wed Nov  1 12:51:21 1995  Per Bothner  <bothner@kalessin.cygnus.com>
 137
 138         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 139         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 140         on info).
 141
 142 Wed Nov  1 15:23:15 1995  Manfred Hollstein KS/EF4A 60/1F/110 #40283  <manfred@lts.sel.alcatel.de>
 143

 148         * Makefile.in (diststuff):  Also make info.
 149         (mostlyclean):  Don't remove gprof.info*.
 150         (maintainer-clean realclean):  Also remove *.info*.
 151
 152 Fri Oct  6 16:25:32 1995  Ken Raeburn  <raeburn@cygnus.com>
 153
 154         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 155
 156         * Makefile.in: Add dependecies for $(OBJS) on header files.
 157
 158         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 159         style output format to make it consistent.
 160         * dummy.c (find_call): Fix typo in error message.
 161
 162 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 163
 164         * Makefile.in (maintainer-clean): New target, synonym for
 165         realclean.
 166
 167 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 168
 169         * Makefile.in (install): Don't install in $(tooldir).

 175         * ns532.c: Include symtab.h.
 176         (find_call): Renamed from findcall.  Print a message.
 177         * ns532.h: Remove dummy.h comments.
 178
 179 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 180
 181         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 182         that we're using autoconf.
 183
 184 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 185
 186         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
 187         to proper type of "unsigned int *".
 188
 189 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 190
 191         * configure.in: Use changequote around use of [].
 192
 193 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 194
 195         * Makefile.in (distclean, realclean): Remove config.cache and
 196           config.log.
 197
 198 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 199
 200         * Makefile.in (Makefile): Added config.status to dependency list.
 201           (config.status): New target.
 202           (SHELL): New definition.
 203
 204 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 205
 206         * Makefile.in (install): Depend on "all".
 207
 208 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 209
 210         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 211         to match configure script.
 212
 213 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 214
 215         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 216           comment emitted by this script to gen-c-prog.awk.
 217
 218         * Makefile.in, configure.in: Converted to use autoconf.
 219         * configure: New file, generated with autoconf 2.3.
 220         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 221           mt-tahoe, mt-vax}: Removed.
 222
 223 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 224
 225         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 226
 227         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 228
 229         * All *.c: More cleanup towards GNU format.
 230
 231         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 232         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 233         that bfd_vma is only guaranteed to be at least as big as a pointer.
 234
 235         (GMON_Record_tag): added explicit enumeration values to ensure
 236         compatibility across compilers.
 237
 238         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 239         sizeof(char*).
 240
 241 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 242
 243         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 244         of constructs GNU indent couldn't handle.  Block comments not yet
 245         rewritten in GNU format.
 246
 247         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 248         binutils release.
 249
 250 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 251
 252         * symtab.c (symtab_finalize): ensure globals symbols really
 253         are favored over static ones---even if their name looks less
 254         preferable; this is important for HP-UX; for example, there
 255         is a static label Ltext_something that aliases the global
 256         symbol _start
 257
 258         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 259         output only; also, auto-scaling is now performed based on
 260         per-call, rather than total execution time, which is what it was
 261         meant to be.
 262
 263         * gprof.h (File_Format): new type.
 264
 265         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 266         sync with Cygnus version numbers though...
 267
 268         (long_options): renamed --gmon-info to --file-info, --width added,
 269         renamed --old-file-format to --file-format
 270         (main): dito; also added support to read prof files, but as
 271         mon_out_read() is not implemented, it's #ifdef'd out for now
 272
 273         (usage): update to reflect new options.
 274
 275         * gmon_io.c: replaced "old_file_format" by more general
 276         "file_format" option
 277
 278         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 279
 280         * core.c (core_sym_class): added back check for __gnu_compiled and
 281         ___gnu_compiled for the benefit of systems without
 282         bfd_find_nearest_line() support
 283
 284         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 285         with section-relative addresses
 286
 287         (core_create_function_syms): get_src_info() calls are currently
 288         enabled for OSF/1 only.  It appears to work allright for SunOS
 289         4.1.x as well, but on SPARCs it gets painfully slow with the
 290         current implementation of aout_32_find_nearest_line();
 291         unfortunately, this means that static functions will not have their
 292         filename printed in the call-graph function index; line-level
 293         profiling should still work, but requires some patience
 294
 295         * cg_print.c (cg_print_index): sanitized printing of index when
 296         using FSF-style output; in particular, output width is now controlled
 297         via option --width and the function tries hard to keep columns
 298         aligned even in the presence of (occasional) long names
 299
 300         * NOTES: a first shot at updating the documentation.
 301
 302 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 303
 304         * core.c (core_create_function_syms): fixed computation of min_vma
 305         and max_vma.
 306
 307         * *.c: removed rcsid.
 308
 309 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 310
 311         * Lots of changes from David Mosberger-Tang:
 312
 313         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 314
 315         * gprof.c (main): put parentheses around & within &&.
 316
 317         * basic_blocks.c (bb_read_rec): print warning message (once) when
 318         ignoring basic-block execution counts.
 319
 320         * source.c (source_file_lookup_name): corrected second argument to
 321         strcmp().
 322
 323         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 324         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 325
 326         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 327         supported both for old and new (versioned) gmon.out files.  Old
 328         files are identified as version 0.
 329
 330         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 331         long (instead of 4) because that is what OSF/1 v3.0 uses.
 332
 333         * core.c: minor fixes and debugging info changes.
 334
 335         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 336
 337         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 338         name of the text-section under HP-UX).
 339
 340         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 341         points one past the last sampling bin, so hist_scale should be
 342         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 343         hist_num_bins - 1".
 344
 345         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 346         hist_num_bins.
 347
 348         * configure.in: added alpha-*-*) for per-target config.
 349
 350         * alpha.c, alpha.h: created.
 351
 352         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 353
 354         * core.c (core_create_function_syms, core_create_line_syms):
 355         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 356         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 357         addr) continues to guarantee not to return 0 on any address.  It
 358         also avoids incorrectly crediting the first/last symbol in the
 359         text-space.
 360
 361         * core.c (core_create_line_syms): always create function symbols
 362         first, then merge in line symbols; this is so that if parts of the
 363         program were compiled without -g, function-level symbols are
 364         available still.
 365
 366         * utils.c (print_name_only): support for print_path added.
 367
 368         * symtab.c (cmp_addr): also use is_func flag in comparison.
 369         (symtab_finalize): return immediately when table empty; now
 370         more careful about getting rid of the right duplicate symbol.
 371
 372         * sparc.c (find_call): many fixes---this function was rather
 373         botched in binutils-2.4 already; it should work again.
 374
 375         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 376         not good to rely on get_src_info() to return distinct string
 377         pointers).
 378
 379         * search_list.c (search_list_append): added cast for xmalloc().
 380
 381         * hist.c: added explicit initialization to some of the global
 382         variables; fixed SItab (scales were off by a factor of 10).
 383
 384         * hist.h: include of bfd.h added.
 385
 386         * gprof.c, gprof.h (print_path): added.
 387
 388         * gprof.h (MAX): fixed.
 389
 390         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 391
 392         * gmon_io.c: added some casts to (long) so we can always print as %lx
 393
 394         * core.c (core_get_text_space): fixed to make it work.
 395
 396         * cg_print.c (cg_print_index): added support for print_path option.
 397
 398         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 399
 400         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 401         as some compilers complain (e.g., DEC's OSF/1 compiler)
 402
 403         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 404         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 405
 406         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 407
 408         * gprof.c: added "_mcount" to default_excluded_list.
 409         (main): if output_style==0 and there is either a histogram or a
 410         call-graph, always generate flat and call-graph, no matter what
 411         line_granularity is set to.
 412
 413         * source.c (source_file_lookup_name): if searching for sf->name
 414         fails, try again with filename obtained after stripping off any
 415         partial path from sf->name.
 416
 417         * gprof.h (SRCDEBUG): added.
 418
 419         * search_list.c (search_list_append): directories were added in wrong
 420         order.
 421
 422         * reimplemented selection mechanism from ground up; it is now possible
 423         to accurately control what gets included/excluded in each of the
 424         output styles;  a "symbol-specification" (spec) is the basic means
 425         to select a set of symbols; a spec has the syntax:
 426
 427           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 428           arc == spec/spec.
 429
 430         any of the terminal symbols can be empty, in which case they
 431         match anything (wildcards).  NAME is interpreted as a FILENAME
 432         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 433         with a digit, and as FUNCNAME otherwise.
 434
 435         For example, to get a call-graph display that ignores arcs
 436         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 437         show only arcs into bar() (no matter what the caller),
 438         you'd say "--graph=/bar"; and to get a call-graph without
 439         any arc info, you'd say "--graph=/";  similarly, to
 440         get a flat profile without mcount, you'd say "--no-flat=mcount"
 441         and to get a flat profile that shows includes all functions
 442         you'd say "--flat=""" (i.e., an empty spec)
 443
 444         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 445
 446         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 447
 448         * gmon_out.h: all headers now declared in terms of characters
 449           to avoid getting into trouble with different compilers introducing
 450           different amount of padding; the code already accessed the fields
 451           through bfd functions, so that didn't have to change.
 452
 453         * hist.c (hist_read_rec, hist_write_rec): added support for
 454           collection pc histograms measuring quantities other than time;
 455           the histogram header now includes a field that specifies the
 456           dimension of the quantity measured by the histogram bins
 457           (normally, this is "seconds", but other meaningful dimensions
 458            include such things as "I-cache misses", "instruction issue stalls"
 459            etc.); there is also a field to specify a one-character
 460           abbreviation for the dimension; in the case of time, this would
 461           be 's'; in most other cases it probably would be '1' (not a physical
 462           dimension).
 463
 464         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 465
 466         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 467           has become old_file_version; gmon_io.c now always supports old-style
 468           gmon.out files; it first tries to read gmon.out as a new version
 469           file, if that fails, it tries to read it in the old format;
 470           although not very likely, it is possible for gprof to mistake an
 471           old-style file as a new one (the first 4 bytes would have to
 472           be "gmon"---including the trailing '\0'); in that case, it is
 473           necessary to specify --old-file-version
 474
 475         * gprof.h: removed dependency on SYSV; the code now always uses
 476           strrchr(), memset(), and memcpy() and does not include either
 477           of string.h or strings.h; this should make gprof compile on
 478           any (Unix) system without configuration (per suggestion of
 479           raeburn@cygnus.com)
 480
 481         * gprof.c (usage): fixed location of --new-file-format option.
 482
 483         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 484
 485         * flat_bl.m: removed formfeed at end of file; the form-feed
 486           is now printed cg_print.c only when necessary.
 487
 488         * major rewrite of gprof---too many changes to mention all of
 489           them.  new features:
 490
 491         + -l now requests profiling at the line level (as opposed
 492           to function level); in this mode, gprof creates a "symbol"
 493           (aka name-list entry) for each line of source code, instead
 494            of one per function)
 495
 496         + support for a new gmon.out file format; the new format
 497           consists of a header with a magic and a version number,
 498           followed by a sequence of profile data; profile data
 499           can any of: (a) PC histogram, (b) call-graph arcs, or
 500           (c) basic-block execution counts; the version number makes
 501           it possible to extend gmon.out in a backwards compatible
 502           fashion
 503
 504         + support for tcov style annotated output: if the gmon.out file
 505           contains basic-block execution counts, the user can request
 506           the generation of annotated source files, much like Sun's
 507           tcov used to do
 508
 509         + long options
 510
 511         + new scheme to suppress symbols that aren't function names
 512           (e.g., avoids mistaking a goto label as a function)
 513
 514         + reorganized source code to make it more managable; as a
 515           side effect, gprof now compiles cleanly with "gcc -Wall"
 516
 517         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 518
 519         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 520         final cross-check to determine whether a static symbol should be
 521         considered as a function-name.
 522
 523         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 524
 525         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 526         stdin; this is useful if you wanna keep gmon.out files compressed;
 527         this way you can "gzcat" the compressed file into gprof.
 528
 529         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 530
 531         * basic_blocks.c (bb_annotate_source): added support for creating
 532         .tcov files when option flag_annotate_make_files is TRUE.
 533         (annotate_with_count): all counts less than the minimum count
 534         specified by -m are now annotated with hash-marks.
 535
 536         * gprof.c (main): -A is now followed by a string of option chars.
 537
 538         * basic_blocks.c (annotate_with_count): replaced b->count with
 539         cnt.
 540
 541         * source.c: flag_annotate_source replaced by source_lock_map.
 542
 543         * source.h: source_lock_map added.
 544
 545         * gprof.c (main): new command-line syntax: -S simply specifies
 546         which source-files user is interested in; -A requests annotated
 547         source files and -AA requests that all lines in a source file
 548         are annotated.
 549
 550         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 551
 552         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 553
 554         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 555         so s_lowpc etc. get declared.
 556
 557         * arcs.h (doarcs): created.
 558
 559         * arcs.c: reordered static functions such that they get defined
 560         before use.
 561
 562         * gprof.c (main): added options:
 563            -A: request annotation of all source lines (with -S)
 564            -m: minimum execution count (with default basic-block display)
 565            -N: force new file format (only if BSD_COMPATIBLE is defined)
 566            -S: annotate source file
 567            -t: set table length (with -S)
 568
 569         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 570         source.o time_hist.o
 571
 572         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 573
 574         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 575         on the fact being able to store a long in a double without loss of
 576         precision; this does not hold on machines with 64 bit longs and 64
 577         bit doubles.

 579 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>

 581         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 582         greater than 0.0.  Suggested by Harold Assink
 583         <carlo@sg.tn.tudelft.nl>.

 585 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 586
 587         * printgprof.c (printprof): Use free, not cfree.
 588         (printgprof, printindex): Ditto.
 589
 590 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 591
 592         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 593         decls extern to keep native HP compiler quiet.
 594
 595 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 596
 597         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 598         __gnu_compiled, for the benefit of systems which add a leading
 599         underscore.

 612         Allows compilation with -Dregister= for debugging.
 613
 614         * configure.in: Add ns532 support.

 653         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
 654         errors from bfd_get_symtab_upper_bound and
 655         bfd_canonicalize_symtab.

 721         Ads LDFLAGS and use in place of CFLAGS where appropriate.
 722         * configure.in:  Make a sysdep.hlink in the same way other
 723         bfd-based directories do.
 724         * gprof.h (UNIT):  Replace non-standard 'u_short' by 'unsigned
 725         short'.
 726         * gprof.h:  #include sysdep.h instead of a bunch of stuff.
 727         * gprof.c (main):  Fix typo gproff->gprof.

 754 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 755
 756         * gprof.1: updated SYNOPSIS to match actual behavior.
 757
 758 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 759
 760         * gen-c-prog.awk:  New awk script, lightly changed from
 761         previously deleted make-c-prog.awk.  Converts a text file
 762         to a c function that prints that text.
 763         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 764         Inputs to gen-c-prog.awk, containing text describing
 765         gprof output.
 766         * blurbs.c:  Removed.  Use *_bl.c instead.
 767         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 768         from *_bl.m files.  Also, improve *clean rules.
 769         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 773
 774         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 775         output styles:  The default is similar to the old FSF gprof,
 776         while -T sets the variable bsd_style_output, which causes
 777         output matching Berkeley's gprof.  The biggest differences
 778         are that with the FSF style output, the flat profile comes
 779         before the call graph; numbers come before explanations;
 780         and there is less gratuitous white space.
 781         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 782         variable causes discarding of initial underscores when
 783         printing symbol names.  It is set unless there is a "main"
 784         symbol (without an underscore).
 785         * printfgprof.c:  New function printnameonly(), called
 786         by printname().  It handles stripping of initial '_',
 787         as well as C++ name-demangling.
 788         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 789         It is just as convenient to edit blurbs.c directly.
 790         * Makefile.in:  Removed rule for making blurbs.c.
 791         * blurbs.c:  This is now a true source file (as opposed
 792         to being generated from gprof.callg and gprof.flat).
 793         Change style to use one long string literal, instead of
 794         one literal per output line.  Add FSF-style blurb for call graph.
 795
 796 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 797
 798         * Makefile.in: always create installation directories.

 805
 806         * Makefile.in:  removed installation of the now useless
 807         call.{flag,callg} files.
 808
 809         * gprof.1: now uses the standard man macros instead of the new BSD
 810         mandoc macros.
 811
 812 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 813
 814         * configure.in:  Remove host section, expand target section.
 815         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 816         * config/tmake-*:  Remove leftover crud.
 817
 818         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 819         * make-c-prog.awk:  which processes text files into C programs.
 820         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 821         to print blurbs.
 822         (printblurb):  Remove.
 823         * Makefile.in:  Infrastructure to build blurbs.
 824         * pathnames.h:  has been removed.  Gprof now has no filename
 825         dependencies in it.
 826         * gprof.c:  Lint.

 836 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 837
 838         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 839         help in debugging the problem (with -DDEBUG)
 840         * gprof.c: symbol values are now real values, don't add the vma
 841         anymore. (done for solaris; should verify this on other platforms)
 842         * ChangeLog: created.
