 161         * Makefile.in (.m.c): Strip out directory name from function
 162         name.
 163
 164         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 165         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 166         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 167
 168         * vax.c: Don't include vax.h here.
 169
 170 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

 184         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 185         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 186         on info).

 201
 202         * Makefile.in: Add dependecies for $(OBJS) on header files.
 203
 204         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 205         style output format to make it consistent.
 206         * dummy.c (find_call): Fix typo in error message.
 207
 208 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 209

 211         realclean.
 212
 213 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>

 224
 225 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 226
 227         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 228         that we're using autoconf.
 229
 230 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 231
 232         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line

 236
 237         * configure.in: Use changequote around use of [].

 239 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 240
 241         * Makefile.in (distclean, realclean): Remove config.cache and
 242           config.log.
 243
 244 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 245
 246         * Makefile.in (Makefile): Added config.status to dependency list.
 247           (config.status): New target.
 248           (SHELL): New definition.
 249
 250 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 251

 253
 254 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 255
 256         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 257         to match configure script.
 258
 259 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>

 268
 269 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 270
 271         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 272
 273         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 274
 275         * All *.c: More cleanup towards GNU format.
 276
 277         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 278         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 279         that bfd_vma is only guaranteed to be at least as big as a pointer.
 280
 281         (GMON_Record_tag): added explicit enumeration values to ensure
 282         compatibility across compilers.
 283
 284         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 285         sizeof(char*).
 286
 287 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 288
 289         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 290         of constructs GNU indent couldn't handle.  Block comments not yet
 291         rewritten in GNU format.
 292
 293         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 294         binutils release.
 295
 296 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 297
 298         * symtab.c (symtab_finalize): ensure globals symbols really
 299         are favored over static ones---even if their name looks less
 300         preferable; this is important for HP-UX; for example, there
 301         is a static label Ltext_something that aliases the global
 302         symbol _start
 303
 304         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 305         output only; also, auto-scaling is now performed based on
 306         per-call, rather than total execution time, which is what it was
 307         meant to be.
 308
 309         * gprof.h (File_Format): new type.
 310
 311         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 312         sync with Cygnus version numbers though...
 313
 314         (long_options): renamed --gmon-info to --file-info, --width added,
 315         renamed --old-file-format to --file-format
 316         (main): dito; also added support to read prof files, but as
 317         mon_out_read() is not implemented, it's #ifdef'd out for now
 318
 319         (usage): update to reflect new options.
 320
 321         * gmon_io.c: replaced "old_file_format" by more general
 322         "file_format" option
 323
 324         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 325
 326         * core.c (core_sym_class): added back check for __gnu_compiled and
 327         ___gnu_compiled for the benefit of systems without
 328         bfd_find_nearest_line() support
 329
 330         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 331         with section-relative addresses
 332
 333         (core_create_function_syms): get_src_info() calls are currently
 334         enabled for OSF/1 only.  It appears to work allright for SunOS
 335         4.1.x as well, but on SPARCs it gets painfully slow with the
 336         current implementation of aout_32_find_nearest_line();
 337         unfortunately, this means that static functions will not have their
 338         filename printed in the call-graph function index; line-level
 339         profiling should still work, but requires some patience
 340
 341         * cg_print.c (cg_print_index): sanitized printing of index when
 342         using FSF-style output; in particular, output width is now controlled
 343         via option --width and the function tries hard to keep columns
 344         aligned even in the presence of (occasional) long names
 345
 346         * NOTES: a first shot at updating the documentation.
 347
 348 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 349
 350         * core.c (core_create_function_syms): fixed computation of min_vma
 351         and max_vma.
 352
 353         * *.c: removed rcsid.
 354
 355 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 356
 357         * Lots of changes from David Mosberger-Tang:
 358
 359         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 360
 361         * gprof.c (main): put parentheses around & within &&.
 362
 363         * basic_blocks.c (bb_read_rec): print warning message (once) when
 364         ignoring basic-block execution counts.
 365
 366         * source.c (source_file_lookup_name): corrected second argument to
 367         strcmp().
 368
 369         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 370         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 371
 372         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 373         supported both for old and new (versioned) gmon.out files.  Old
 374         files are identified as version 0.
 375
 376         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 377         long (instead of 4) because that is what OSF/1 v3.0 uses.
 378
 379         * core.c: minor fixes and debugging info changes.
 380
 381         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 382
 383         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 384         name of the text-section under HP-UX).
 385
 386         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 387         points one past the last sampling bin, so hist_scale should be
 388         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 389         hist_num_bins - 1".
 390
 391         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 392         hist_num_bins.
 393
 394         * configure.in: added alpha-*-*) for per-target config.
 395
 396         * alpha.c, alpha.h: created.
 397
 398         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 399
 400         * core.c (core_create_function_syms, core_create_line_syms):
 401         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 402         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 403         addr) continues to guarantee not to return 0 on any address.  It
 404         also avoids incorrectly crediting the first/last symbol in the
 405         text-space.
 406
 407         * core.c (core_create_line_syms): always create function symbols
 408         first, then merge in line symbols; this is so that if parts of the
 409         program were compiled without -g, function-level symbols are
 410         available still.
 411
 412         * utils.c (print_name_only): support for print_path added.
 413
 414         * symtab.c (cmp_addr): also use is_func flag in comparison.
 415         (symtab_finalize): return immediately when table empty; now
 416         more careful about getting rid of the right duplicate symbol.
 417
 418         * sparc.c (find_call): many fixes---this function was rather
 419         botched in binutils-2.4 already; it should work again.
 420
 421         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 422         not good to rely on get_src_info() to return distinct string
 423         pointers).
 424
 425         * search_list.c (search_list_append): added cast for xmalloc().
 426
 427         * hist.c: added explicit initialization to some of the global
 428         variables; fixed SItab (scales were off by a factor of 10).
 429
 430         * hist.h: include of bfd.h added.
 431
 432         * gprof.c, gprof.h (print_path): added.
 433
 434         * gprof.h (MAX): fixed.
 435
 436         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 437
 438         * gmon_io.c: added some casts to (long) so we can always print as %lx
 439
 440         * core.c (core_get_text_space): fixed to make it work.
 441
 442         * cg_print.c (cg_print_index): added support for print_path option.
 443
 444         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 445
 446         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 447         as some compilers complain (e.g., DEC's OSF/1 compiler)
 448
 449         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 450         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 451
 452         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 453
 454         * gprof.c: added "_mcount" to default_excluded_list.
 455         (main): if output_style==0 and there is either a histogram or a
 456         call-graph, always generate flat and call-graph, no matter what
 457         line_granularity is set to.
 458
 459         * source.c (source_file_lookup_name): if searching for sf->name
 460         fails, try again with filename obtained after stripping off any
 461         partial path from sf->name.
 462
 463         * gprof.h (SRCDEBUG): added.
 464
 465         * search_list.c (search_list_append): directories were added in wrong
 466         order.
 467
 468         * reimplemented selection mechanism from ground up; it is now possible
 469         to accurately control what gets included/excluded in each of the
 470         output styles;  a "symbol-specification" (spec) is the basic means
 471         to select a set of symbols; a spec has the syntax:
 472
 473           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 474           arc == spec/spec.
 475
 476         any of the terminal symbols can be empty, in which case they
 477         match anything (wildcards).  NAME is interpreted as a FILENAME
 478         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 479         with a digit, and as FUNCNAME otherwise.
 480
 481         For example, to get a call-graph display that ignores arcs
 482         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 483         show only arcs into bar() (no matter what the caller),
 484         you'd say "--graph=/bar"; and to get a call-graph without
 485         any arc info, you'd say "--graph=/";  similarly, to
 486         get a flat profile without mcount, you'd say "--no-flat=mcount"
 487         and to get a flat profile that shows includes all functions
 488         you'd say "--flat=""" (i.e., an empty spec)
 489
 490         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 491
 492         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 493
 494         * gmon_out.h: all headers now declared in terms of characters
 495           to avoid getting into trouble with different compilers introducing
 496           different amount of padding; the code already accessed the fields
 497           through bfd functions, so that didn't have to change.
 498
 499         * hist.c (hist_read_rec, hist_write_rec): added support for
 500           collection pc histograms measuring quantities other than time;
 501           the histogram header now includes a field that specifies the
 502           dimension of the quantity measured by the histogram bins
 503           (normally, this is "seconds", but other meaningful dimensions
 504            include such things as "I-cache misses", "instruction issue stalls"
 505            etc.); there is also a field to specify a one-character
 506           abbreviation for the dimension; in the case of time, this would
 507           be 's'; in most other cases it probably would be '1' (not a physical
 508           dimension).
 509
 510         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 511
 512         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 513           has become old_file_version; gmon_io.c now always supports old-style
 514           gmon.out files; it first tries to read gmon.out as a new version
 515           file, if that fails, it tries to read it in the old format;
 516           although not very likely, it is possible for gprof to mistake an
 517           old-style file as a new one (the first 4 bytes would have to
 518           be "gmon"---including the trailing '\0'); in that case, it is
 519           necessary to specify --old-file-version
 520
 521         * gprof.h: removed dependency on SYSV; the code now always uses
 522           strrchr(), memset(), and memcpy() and does not include either
 523           of string.h or strings.h; this should make gprof compile on
 524           any (Unix) system without configuration (per suggestion of
 525           raeburn@cygnus.com)
 526
 527         * gprof.c (usage): fixed location of --new-file-format option.
 528
 529         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 530
 531         * flat_bl.m: removed formfeed at end of file; the form-feed
 532           is now printed cg_print.c only when necessary.
 533
 534         * major rewrite of gprof---too many changes to mention all of
 535           them.  new features:
 536
 537         + -l now requests profiling at the line level (as opposed
 538           to function level); in this mode, gprof creates a "symbol"
 539           (aka name-list entry) for each line of source code, instead
 540            of one per function)
 541
 542         + support for a new gmon.out file format; the new format
 543           consists of a header with a magic and a version number,
 544           followed by a sequence of profile data; profile data
 545           can any of: (a) PC histogram, (b) call-graph arcs, or
 546           (c) basic-block execution counts; the version number makes
 547           it possible to extend gmon.out in a backwards compatible
 548           fashion
 549
 550         + support for tcov style annotated output: if the gmon.out file
 551           contains basic-block execution counts, the user can request
 552           the generation of annotated source files, much like Sun's
 553           tcov used to do
 554
 555         + long options
 556
 557         + new scheme to suppress symbols that aren't function names
 558           (e.g., avoids mistaking a goto label as a function)
 559
 560         + reorganized source code to make it more managable; as a
 561           side effect, gprof now compiles cleanly with "gcc -Wall"
 562
 563         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 564
 565         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 566         final cross-check to determine whether a static symbol should be
 567         considered as a function-name.
 568
 569         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 570
 571         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 572         stdin; this is useful if you wanna keep gmon.out files compressed;
 573         this way you can "gzcat" the compressed file into gprof.
 574
 575         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 576
 577         * basic_blocks.c (bb_annotate_source): added support for creating
 578         .tcov files when option flag_annotate_make_files is TRUE.
 579         (annotate_with_count): all counts less than the minimum count
 580         specified by -m are now annotated with hash-marks.
 581
 582         * gprof.c (main): -A is now followed by a string of option chars.
 583
 584         * basic_blocks.c (annotate_with_count): replaced b->count with
 585         cnt.
 586
 587         * source.c: flag_annotate_source replaced by source_lock_map.
 588
 589         * source.h: source_lock_map added.
 590
 591         * gprof.c (main): new command-line syntax: -S simply specifies
 592         which source-files user is interested in; -A requests annotated
 593         source files and -AA requests that all lines in a source file
 594         are annotated.
 595
 596         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 597
 598         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 599
 600         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 601         so s_lowpc etc. get declared.
 602
 603         * arcs.h (doarcs): created.
 604
 605         * arcs.c: reordered static functions such that they get defined
 606         before use.
 607
 608         * gprof.c (main): added options:
 609            -A: request annotation of all source lines (with -S)
 610            -m: minimum execution count (with default basic-block display)
 611            -N: force new file format (only if BSD_COMPATIBLE is defined)
 612            -S: annotate source file
 613            -t: set table length (with -S)
 614
 615         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 616         source.o time_hist.o
 617
 618         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 619
 620         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 621         on the fact being able to store a long in a double without loss of
 622         precision; this does not hold on machines with 64 bit longs and 64
 623         bit doubles.
 624
 625 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 626
 627         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 628         greater than 0.0.  Suggested by Harold Assink
 629         <carlo@sg.tn.tudelft.nl>.

 631 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 632
 633         * printgprof.c (printprof): Use free, not cfree.
 634         (printgprof, printindex): Ditto.
 635
 636 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 637
 638         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 639         decls extern to keep native HP compiler quiet.
 640
 641 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 642
 643         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 644         __gnu_compiled, for the benefit of systems which add a leading
 645         underscore.
 646
 647 Wed Aug 24 12:49:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 648
 649         * configure.in: Change i386-*-* to i[345]86-*-*.

 651 Sun Jul 10 00:35:31 1994  Ian Dall  (dall@hfrd.dsto.gov.au)
 652
 653         * ns532.c, ns532.h: New Files. ns532 support.
 654
 655         * config/mt-ns532: New File. ns532 support.
 656
 657         * gprof.c: user register int i instead of defaulting the int.
 658         Allows compilation with -Dregister= for debugging.
 659
 660         * configure.in: Add ns532 support.

 671
 672         * configure.bat: [new] build makefile from makefile.in (dos)
 673         * hertz.c: allow static HERTZ (msdos needs it)
 674         * gprof.c: allow target to select "r" or "rb" for fopen
 675         * gprof.c: ignore __gnu_compiled symbols

 679
 680         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 681         so flat_bl.c would make from flat_bl.m file.
 682
 683 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 684
 685         * Makefile.in (install-info): Check for gprof.info in build dir,
 686         fall back to srcdir.  Depend on it.
 687
 688         * gprof.h (TRUE, FALSE): Always use undef before defining them.

 690 Mon Apr  4 23:47:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 691
 692         * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
 693         makes (osf1) in which the value of MACHINE can not be changed.
 694         * config/*.mt: Changed appropriately.
 695
 696 Wed Mar 30 16:12:40 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 697
 698         * gprof.c (getsymtab): Change nosyms to long.  Rename
 699         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
 700         errors from bfd_get_symtab_upper_bound and
 701         bfd_canonicalize_symtab.

 802         * gprof.1: updated SYNOPSIS to match actual behavior.
 803
 804 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 805
 806         * gen-c-prog.awk:  New awk script, lightly changed from
 807         previously deleted make-c-prog.awk.  Converts a text file
 808         to a c function that prints that text.
 809         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 810         Inputs to gen-c-prog.awk, containing text describing
 811         gprof output.
 812         * blurbs.c:  Removed.  Use *_bl.c instead.
 813         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 814         from *_bl.m files.  Also, improve *clean rules.
 815         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 818 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 819
 820         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 821         output styles:  The default is similar to the old FSF gprof,
 822         while -T sets the variable bsd_style_output, which causes
 823         output matching Berkeley's gprof.  The biggest differences
 824         are that with the FSF style output, the flat profile comes
 825         before the call graph; numbers come before explanations;
 826         and there is less gratuitous white space.
 827         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 828         variable causes discarding of initial underscores when
 829         printing symbol names.  It is set unless there is a "main"
 830         symbol (without an underscore).
 831         * printfgprof.c:  New function printnameonly(), called
 832         by printname().  It handles stripping of initial '_',
 833         as well as C++ name-demangling.
 834         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 835         It is just as convenient to edit blurbs.c directly.
 836         * Makefile.in:  Removed rule for making blurbs.c.
 837         * blurbs.c:  This is now a true source file (as opposed
 838         to being generated from gprof.callg and gprof.flat).
 839         Change style to use one long string literal, instead of
 840         one literal per output line.  Add FSF-style blurb for call graph.
 841
 842 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 843
 844         * Makefile.in: always create installation directories.
 845
 846 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 847
 848         * Makefile.in: change ${MACHINE} to $(MACHINE).

 851
 852         * Makefile.in:  removed installation of the now useless
 853         call.{flag,callg} files.
 854
 855         * gprof.1: now uses the standard man macros instead of the new BSD
 856         mandoc macros.
 857
 858 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 859
 860         * configure.in:  Remove host section, expand target section.
 861         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 862         * config/tmake-*:  Remove leftover crud.
 863
 864         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 865         * make-c-prog.awk:  which processes text files into C programs.
 866         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 867         to print blurbs.
 868         (printblurb):  Remove.
 869         * Makefile.in:  Infrastructure to build blurbs.
 870         * pathnames.h:  has been removed.  Gprof now has no filename
 871         dependencies in it.
 872         * gprof.c:  Lint.

 881
 882 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 883
 884         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 885         help in debugging the problem (with -DDEBUG)
 886         * gprof.c: symbol values are now real values, don't add the vma
 887         anymore. (done for solaris; should verify this on other platforms)
 888         * ChangeLog: created.
