 173         * Makefile.in (.m.c): Strip out directory name from function
 174         name.
 175
 176         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 177         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 178         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 179
 180         * vax.c: Don't include vax.h here.
 181
 182 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

 196         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 197         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 198         on info).
 199

 212         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 213
 214         * Makefile.in: Add dependecies for $(OBJS) on header files.
 215
 216         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 217         style output format to make it consistent.
 218         * dummy.c (find_call): Fix typo in error message.
 219
 220 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 221
 222         * Makefile.in (maintainer-clean): New target, synonym for
 223         realclean.
 224
 225 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 226

 236
 237 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 238
 239         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 240         that we're using autoconf.
 241
 242 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 243
 244         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line

 256 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 257

 261
 262 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>

 265
 266 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 267
 268         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 269         to match configure script.
 270
 271 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>

 280
 281 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 282

 284
 285         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 286
 287         * All *.c: More cleanup towards GNU format.
 288
 289         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 290         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 291         that bfd_vma is only guaranteed to be at least as big as a pointer.
 292
 293         (GMON_Record_tag): added explicit enumeration values to ensure
 294         compatibility across compilers.
 295
 296         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 297         sizeof(char*).
 298
 299 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 300
 301         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 302         of constructs GNU indent couldn't handle.  Block comments not yet
 303         rewritten in GNU format.
 304
 305         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 306         binutils release.
 307
 308 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 309
 310         * symtab.c (symtab_finalize): ensure globals symbols really
 311         are favored over static ones---even if their name looks less
 312         preferable; this is important for HP-UX; for example, there
 313         is a static label Ltext_something that aliases the global
 314         symbol _start
 315
 316         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 317         output only; also, auto-scaling is now performed based on
 318         per-call, rather than total execution time, which is what it was
 319         meant to be.
 320
 321         * gprof.h (File_Format): new type.
 322
 323         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 324         sync with Cygnus version numbers though...
 325
 326         (long_options): renamed --gmon-info to --file-info, --width added,
 327         renamed --old-file-format to --file-format
 328         (main): dito; also added support to read prof files, but as
 329         mon_out_read() is not implemented, it's #ifdef'd out for now
 330
 331         (usage): update to reflect new options.
 332
 333         * gmon_io.c: replaced "old_file_format" by more general
 334         "file_format" option
 335
 336         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 337
 338         * core.c (core_sym_class): added back check for __gnu_compiled and
 339         ___gnu_compiled for the benefit of systems without
 340         bfd_find_nearest_line() support
 341
 342         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 343         with section-relative addresses
 344
 345         (core_create_function_syms): get_src_info() calls are currently
 346         enabled for OSF/1 only.  It appears to work allright for SunOS
 347         4.1.x as well, but on SPARCs it gets painfully slow with the
 348         current implementation of aout_32_find_nearest_line();
 349         unfortunately, this means that static functions will not have their
 350         filename printed in the call-graph function index; line-level
 351         profiling should still work, but requires some patience
 352
 353         * cg_print.c (cg_print_index): sanitized printing of index when
 354         using FSF-style output; in particular, output width is now controlled
 355         via option --width and the function tries hard to keep columns
 356         aligned even in the presence of (occasional) long names
 357
 358         * NOTES: a first shot at updating the documentation.
 359
 360 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 361
 362         * core.c (core_create_function_syms): fixed computation of min_vma
 363         and max_vma.
 364
 365         * *.c: removed rcsid.
 366
 367 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 368
 369         * Lots of changes from David Mosberger-Tang:
 370
 371         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 372
 373         * gprof.c (main): put parentheses around & within &&.
 374
 375         * basic_blocks.c (bb_read_rec): print warning message (once) when
 376         ignoring basic-block execution counts.
 377
 378         * source.c (source_file_lookup_name): corrected second argument to
 379         strcmp().
 380
 381         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 382         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 383
 384         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 385         supported both for old and new (versioned) gmon.out files.  Old
 386         files are identified as version 0.
 387
 388         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 389         long (instead of 4) because that is what OSF/1 v3.0 uses.
 390
 391         * core.c: minor fixes and debugging info changes.
 392
 393         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 394
 395         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 396         name of the text-section under HP-UX).
 397
 398         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 399         points one past the last sampling bin, so hist_scale should be
 400         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 401         hist_num_bins - 1".
 402
 403         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 404         hist_num_bins.
 405
 406         * configure.in: added alpha-*-*) for per-target config.
 407
 408         * alpha.c, alpha.h: created.
 409
 410         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 411
 412         * core.c (core_create_function_syms, core_create_line_syms):
 413         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 414         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 415         addr) continues to guarantee not to return 0 on any address.  It
 416         also avoids incorrectly crediting the first/last symbol in the
 417         text-space.
 418
 419         * core.c (core_create_line_syms): always create function symbols
 420         first, then merge in line symbols; this is so that if parts of the
 421         program were compiled without -g, function-level symbols are
 422         available still.
 423
 424         * utils.c (print_name_only): support for print_path added.
 425
 426         * symtab.c (cmp_addr): also use is_func flag in comparison.
 427         (symtab_finalize): return immediately when table empty; now
 428         more careful about getting rid of the right duplicate symbol.
 429
 430         * sparc.c (find_call): many fixes---this function was rather
 431         botched in binutils-2.4 already; it should work again.
 432
 433         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 434         not good to rely on get_src_info() to return distinct string
 435         pointers).
 436
 437         * search_list.c (search_list_append): added cast for xmalloc().
 438
 439         * hist.c: added explicit initialization to some of the global
 440         variables; fixed SItab (scales were off by a factor of 10).
 441
 442         * hist.h: include of bfd.h added.
 443
 444         * gprof.c, gprof.h (print_path): added.
 445
 446         * gprof.h (MAX): fixed.
 447
 448         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 449
 450         * gmon_io.c: added some casts to (long) so we can always print as %lx
 451
 452         * core.c (core_get_text_space): fixed to make it work.
 453
 454         * cg_print.c (cg_print_index): added support for print_path option.
 455
 456         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 457
 458         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 459         as some compilers complain (e.g., DEC's OSF/1 compiler)
 460
 461         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 462         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 463
 464         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 465
 466         * gprof.c: added "_mcount" to default_excluded_list.
 467         (main): if output_style==0 and there is either a histogram or a
 468         call-graph, always generate flat and call-graph, no matter what
 469         line_granularity is set to.
 470
 471         * source.c (source_file_lookup_name): if searching for sf->name
 472         fails, try again with filename obtained after stripping off any
 473         partial path from sf->name.
 474
 475         * gprof.h (SRCDEBUG): added.
 476
 477         * search_list.c (search_list_append): directories were added in wrong
 478         order.
 479
 480         * reimplemented selection mechanism from ground up; it is now possible
 481         to accurately control what gets included/excluded in each of the
 482         output styles;  a "symbol-specification" (spec) is the basic means
 483         to select a set of symbols; a spec has the syntax:
 484
 485           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 486           arc == spec/spec.
 487
 488         any of the terminal symbols can be empty, in which case they
 489         match anything (wildcards).  NAME is interpreted as a FILENAME
 490         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 491         with a digit, and as FUNCNAME otherwise.
 492
 493         For example, to get a call-graph display that ignores arcs
 494         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 495         show only arcs into bar() (no matter what the caller),
 496         you'd say "--graph=/bar"; and to get a call-graph without
 497         any arc info, you'd say "--graph=/";  similarly, to
 498         get a flat profile without mcount, you'd say "--no-flat=mcount"
 499         and to get a flat profile that shows includes all functions
 500         you'd say "--flat=""" (i.e., an empty spec)
 501
 502         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 503
 504         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 505
 506         * gmon_out.h: all headers now declared in terms of characters
 507           to avoid getting into trouble with different compilers introducing
 508           different amount of padding; the code already accessed the fields
 509           through bfd functions, so that didn't have to change.
 510
 511         * hist.c (hist_read_rec, hist_write_rec): added support for
 512           collection pc histograms measuring quantities other than time;
 513           the histogram header now includes a field that specifies the
 514           dimension of the quantity measured by the histogram bins
 515           (normally, this is "seconds", but other meaningful dimensions
 516            include such things as "I-cache misses", "instruction issue stalls"
 517            etc.); there is also a field to specify a one-character
 518           abbreviation for the dimension; in the case of time, this would
 519           be 's'; in most other cases it probably would be '1' (not a physical
 520           dimension).
 521
 522         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 523
 524         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 525           has become old_file_version; gmon_io.c now always supports old-style
 526           gmon.out files; it first tries to read gmon.out as a new version
 527           file, if that fails, it tries to read it in the old format;
 528           although not very likely, it is possible for gprof to mistake an
 529           old-style file as a new one (the first 4 bytes would have to
 530           be "gmon"---including the trailing '\0'); in that case, it is
 531           necessary to specify --old-file-version
 532
 533         * gprof.h: removed dependency on SYSV; the code now always uses
 534           strrchr(), memset(), and memcpy() and does not include either
 535           of string.h or strings.h; this should make gprof compile on
 536           any (Unix) system without configuration (per suggestion of
 537           raeburn@cygnus.com)
 538
 539         * gprof.c (usage): fixed location of --new-file-format option.
 540
 541         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 542
 543         * flat_bl.m: removed formfeed at end of file; the form-feed
 544           is now printed cg_print.c only when necessary.
 545
 546         * major rewrite of gprof---too many changes to mention all of
 547           them.  new features:
 548
 549         + -l now requests profiling at the line level (as opposed
 550           to function level); in this mode, gprof creates a "symbol"
 551           (aka name-list entry) for each line of source code, instead
 552            of one per function)
 553
 554         + support for a new gmon.out file format; the new format
 555           consists of a header with a magic and a version number,
 556           followed by a sequence of profile data; profile data
 557           can any of: (a) PC histogram, (b) call-graph arcs, or
 558           (c) basic-block execution counts; the version number makes
 559           it possible to extend gmon.out in a backwards compatible
 560           fashion
 561
 562         + support for tcov style annotated output: if the gmon.out file
 563           contains basic-block execution counts, the user can request
 564           the generation of annotated source files, much like Sun's
 565           tcov used to do
 566
 567         + long options
 568
 569         + new scheme to suppress symbols that aren't function names
 570           (e.g., avoids mistaking a goto label as a function)
 571
 572         + reorganized source code to make it more managable; as a
 573           side effect, gprof now compiles cleanly with "gcc -Wall"
 574
 575         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 576
 577         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 578         final cross-check to determine whether a static symbol should be
 579         considered as a function-name.
 580
 581         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 582
 583         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 584         stdin; this is useful if you wanna keep gmon.out files compressed;
 585         this way you can "gzcat" the compressed file into gprof.
 586
 587         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 588
 589         * basic_blocks.c (bb_annotate_source): added support for creating
 590         .tcov files when option flag_annotate_make_files is TRUE.
 591         (annotate_with_count): all counts less than the minimum count
 592         specified by -m are now annotated with hash-marks.
 593
 594         * gprof.c (main): -A is now followed by a string of option chars.
 595
 596         * basic_blocks.c (annotate_with_count): replaced b->count with
 597         cnt.
 598
 599         * source.c: flag_annotate_source replaced by source_lock_map.
 600
 601         * source.h: source_lock_map added.
 602
 603         * gprof.c (main): new command-line syntax: -S simply specifies
 604         which source-files user is interested in; -A requests annotated
 605         source files and -AA requests that all lines in a source file
 606         are annotated.
 607
 608         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 609
 610         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 611
 612         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 613         so s_lowpc etc. get declared.
 614
 615         * arcs.h (doarcs): created.
 616
 617         * arcs.c: reordered static functions such that they get defined
 618         before use.
 619
 620         * gprof.c (main): added options:
 621            -A: request annotation of all source lines (with -S)
 622            -m: minimum execution count (with default basic-block display)
 623            -N: force new file format (only if BSD_COMPATIBLE is defined)
 624            -S: annotate source file
 625            -t: set table length (with -S)
 626
 627         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 628         source.o time_hist.o
 629
 630         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 631
 632         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 633         on the fact being able to store a long in a double without loss of
 634         precision; this does not hold on machines with 64 bit longs and 64
 635         bit doubles.
 636
 637 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 638
 639         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 640         greater than 0.0.  Suggested by Harold Assink
 641         <carlo@sg.tn.tudelft.nl>.
 642
 643 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 644
 645         * printgprof.c (printprof): Use free, not cfree.
 646         (printgprof, printindex): Ditto.
 647
 648 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 649
 650         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 651         decls extern to keep native HP compiler quiet.
 652
 653 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 654
 655         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 656         __gnu_compiled, for the benefit of systems which add a leading
 657         underscore.
 658
 659 Wed Aug 24 12:49:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 660
 661         * configure.in: Change i386-*-* to i[345]86-*-*.
 662
 663 Sun Jul 10 00:35:31 1994  Ian Dall  (dall@hfrd.dsto.gov.au)
 664
 665         * ns532.c, ns532.h: New Files. ns532 support.
 666
 667         * config/mt-ns532: New File. ns532 support.
 668
 669         * gprof.c: user register int i instead of defaulting the int.
 670         Allows compilation with -Dregister= for debugging.
 671
 672         * configure.in: Add ns532 support.
 673
 674 Thu Jun 23 11:22:41 1994  Jeff Law  (law@snake.cs.utah.edu)
 675
 676         * Makefile.in (gprof): Depend on $(LIBS).
 677
 678 Fri May 27 12:24:57 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 679
 680         From binutils-2.4 release:
 681
 682         Wed May 11 22:32:00 1994  DJ Delorie (dj@ctron.com)
 683
 684         * configure.bat: [new] build makefile from makefile.in (dos)
 685         * hertz.c: allow static HERTZ (msdos needs it)
 686         * gprof.c: allow target to select "r" or "rb" for fopen
 687         * gprof.c: ignore __gnu_compiled symbols
 688         * i386.h: dfine FOPEN_RB to "rb" for dos.
 689
 690 Tue May 17 15:30:22 1994  E. Michael Smith (ems@cygnus.com)
 691
 692         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 693         so flat_bl.c would make from flat_bl.m file.
 694
 695 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 696
 697         * Makefile.in (install-info): Check for gprof.info in build dir,
 698         fall back to srcdir.  Depend on it.
 699
 700         * gprof.h (TRUE, FALSE): Always use undef before defining them.
 701
 702 Mon Apr  4 23:47:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 703
 704         * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
 705         makes (osf1) in which the value of MACHINE can not be changed.
 706         * config/*.mt: Changed appropriately.
 707
 708 Wed Mar 30 16:12:40 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 709
 710         * gprof.c (getsymtab): Change nosyms to long.  Rename
 711         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
 712         errors from bfd_get_symtab_upper_bound and
 713         bfd_canonicalize_symtab.
 714
 715 Tue Mar 22 10:50:52 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 716
 717         * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of

 815
 816 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 817
 818         * gen-c-prog.awk:  New awk script, lightly changed from
 819         previously deleted make-c-prog.awk.  Converts a text file
 820         to a c function that prints that text.
 821         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 822         Inputs to gen-c-prog.awk, containing text describing
 823         gprof output.
 824         * blurbs.c:  Removed.  Use *_bl.c instead.
 825         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 826         from *_bl.m files.  Also, improve *clean rules.
 827         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 830 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 831
 832         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 833         output styles:  The default is similar to the old FSF gprof,
 834         while -T sets the variable bsd_style_output, which causes
 835         output matching Berkeley's gprof.  The biggest differences
 836         are that with the FSF style output, the flat profile comes
 837         before the call graph; numbers come before explanations;
 838         and there is less gratuitous white space.
 839         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 840         variable causes discarding of initial underscores when
 841         printing symbol names.  It is set unless there is a "main"
 842         symbol (without an underscore).
 843         * printfgprof.c:  New function printnameonly(), called
 844         by printname().  It handles stripping of initial '_',
 845         as well as C++ name-demangling.
 846         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 847         It is just as convenient to edit blurbs.c directly.
 848         * Makefile.in:  Removed rule for making blurbs.c.
 849         * blurbs.c:  This is now a true source file (as opposed
 850         to being generated from gprof.callg and gprof.flat).
 851         Change style to use one long string literal, instead of
 852         one literal per output line.  Add FSF-style blurb for call graph.
 853
 854 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 855
 856         * Makefile.in: always create installation directories.

 858 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)

 863
 864         * Makefile.in:  removed installation of the now useless
 865         call.{flag,callg} files.
 866
 867         * gprof.1: now uses the standard man macros instead of the new BSD
 868         mandoc macros.
 869
 870 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 871
 872         * configure.in:  Remove host section, expand target section.
 873         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 874         * config/tmake-*:  Remove leftover crud.
 875
 876         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 877         * make-c-prog.awk:  which processes text files into C programs.
 878         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 879         to print blurbs.
 880         (printblurb):  Remove.
 881         * Makefile.in:  Infrastructure to build blurbs.
 882         * pathnames.h:  has been removed.  Gprof now has no filename
 883         dependencies in it.
 884         * gprof.c:  Lint.

 893
 894 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 895
 896         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 897         help in debugging the problem (with -DDEBUG)
 898         * gprof.c: symbol values are now real values, don't add the vma
 899         anymore. (done for solaris; should verify this on other platforms)
 900         * ChangeLog: created.
