 148         * Makefile.in (.m.c): Strip out directory name from function
 149         name.
 150
 151         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 152         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 153         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 154
 155         * vax.c: Don't include vax.h here.
 156
 157 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

 171         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 172         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 173         on info).
 174

 186
 187         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 188
 189         * Makefile.in: Add dependecies for $(OBJS) on header files.
 190
 191         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 192         style output format to make it consistent.
 193         * dummy.c (find_call): Fix typo in error message.
 194
 195 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 196
 197         * Makefile.in (maintainer-clean): New target, synonym for
 198         realclean.
 199
 200 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 201

 211
 212 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 213
 214         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 215         that we're using autoconf.
 216
 217 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 218
 219         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line

 223
 224         * configure.in: Use changequote around use of [].

 226 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 227
 228         * Makefile.in (distclean, realclean): Remove config.cache and
 229           config.log.
 230
 231 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 232
 233         * Makefile.in (Makefile): Added config.status to dependency list.
 234           (config.status): New target.
 235           (SHELL): New definition.
 236
 237 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 238
 239         * Makefile.in (install): Depend on "all".
 240
 241 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 242
 243         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 244         to match configure script.
 245
 246 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 247
 248         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in

 255
 256 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 257
 258         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 259
 260         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 261
 262         * All *.c: More cleanup towards GNU format.
 263
 264         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 265         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 266         that bfd_vma is only guaranteed to be at least as big as a pointer.
 267
 268         (GMON_Record_tag): added explicit enumeration values to ensure
 269         compatibility across compilers.
 270
 271         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 272         sizeof(char*).
 273
 274 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 275
 276         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 277         of constructs GNU indent couldn't handle.  Block comments not yet
 278         rewritten in GNU format.
 279
 280         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 281         binutils release.
 282
 283 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 284
 285         * symtab.c (symtab_finalize): ensure globals symbols really
 286         are favored over static ones---even if their name looks less
 287         preferable; this is important for HP-UX; for example, there
 288         is a static label Ltext_something that aliases the global
 289         symbol _start
 290
 291         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 292         output only; also, auto-scaling is now performed based on
 293         per-call, rather than total execution time, which is what it was
 294         meant to be.
 295
 296         * gprof.h (File_Format): new type.
 297
 298         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 299         sync with Cygnus version numbers though...
 300
 301         (long_options): renamed --gmon-info to --file-info, --width added,
 302         renamed --old-file-format to --file-format
 303         (main): dito; also added support to read prof files, but as
 304         mon_out_read() is not implemented, it's #ifdef'd out for now
 305
 306         (usage): update to reflect new options.
 307
 308         * gmon_io.c: replaced "old_file_format" by more general
 309         "file_format" option
 310
 311         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 312
 313         * core.c (core_sym_class): added back check for __gnu_compiled and
 314         ___gnu_compiled for the benefit of systems without
 315         bfd_find_nearest_line() support
 316
 317         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 318         with section-relative addresses
 319
 320         (core_create_function_syms): get_src_info() calls are currently
 321         enabled for OSF/1 only.  It appears to work allright for SunOS
 322         4.1.x as well, but on SPARCs it gets painfully slow with the
 323         current implementation of aout_32_find_nearest_line();
 324         unfortunately, this means that static functions will not have their
 325         filename printed in the call-graph function index; line-level
 326         profiling should still work, but requires some patience
 327
 328         * cg_print.c (cg_print_index): sanitized printing of index when
 329         using FSF-style output; in particular, output width is now controlled
 330         via option --width and the function tries hard to keep columns
 331         aligned even in the presence of (occasional) long names
 332
 333         * NOTES: a first shot at updating the documentation.
 334
 335 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 336
 337         * core.c (core_create_function_syms): fixed computation of min_vma
 338         and max_vma.
 339
 340         * *.c: removed rcsid.
 341
 342 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 343
 344         * Lots of changes from David Mosberger-Tang:
 345
 346         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 347
 348         * gprof.c (main): put parentheses around & within &&.
 349
 350         * basic_blocks.c (bb_read_rec): print warning message (once) when
 351         ignoring basic-block execution counts.
 352
 353         * source.c (source_file_lookup_name): corrected second argument to
 354         strcmp().
 355
 356         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 357         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 358
 359         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 360         supported both for old and new (versioned) gmon.out files.  Old
 361         files are identified as version 0.
 362
 363         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 364         long (instead of 4) because that is what OSF/1 v3.0 uses.
 365
 366         * core.c: minor fixes and debugging info changes.
 367
 368         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 369
 370         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 371         name of the text-section under HP-UX).
 372
 373         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 374         points one past the last sampling bin, so hist_scale should be
 375         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 376         hist_num_bins - 1".
 377
 378         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 379         hist_num_bins.
 380
 381         * configure.in: added alpha-*-*) for per-target config.
 382
 383         * alpha.c, alpha.h: created.
 384
 385         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 386
 387         * core.c (core_create_function_syms, core_create_line_syms):
 388         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 389         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 390         addr) continues to guarantee not to return 0 on any address.  It
 391         also avoids incorrectly crediting the first/last symbol in the
 392         text-space.
 393
 394         * core.c (core_create_line_syms): always create function symbols
 395         first, then merge in line symbols; this is so that if parts of the
 396         program were compiled without -g, function-level symbols are
 397         available still.
 398
 399         * utils.c (print_name_only): support for print_path added.
 400
 401         * symtab.c (cmp_addr): also use is_func flag in comparison.
 402         (symtab_finalize): return immediately when table empty; now
 403         more careful about getting rid of the right duplicate symbol.
 404
 405         * sparc.c (find_call): many fixes---this function was rather
 406         botched in binutils-2.4 already; it should work again.
 407
 408         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 409         not good to rely on get_src_info() to return distinct string
 410         pointers).
 411
 412         * search_list.c (search_list_append): added cast for xmalloc().
 413
 414         * hist.c: added explicit initialization to some of the global
 415         variables; fixed SItab (scales were off by a factor of 10).
 416
 417         * hist.h: include of bfd.h added.
 418
 419         * gprof.c, gprof.h (print_path): added.
 420
 421         * gprof.h (MAX): fixed.
 422
 423         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 424
 425         * gmon_io.c: added some casts to (long) so we can always print as %lx
 426
 427         * core.c (core_get_text_space): fixed to make it work.
 428
 429         * cg_print.c (cg_print_index): added support for print_path option.
 430
 431         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 432
 433         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 434         as some compilers complain (e.g., DEC's OSF/1 compiler)
 435
 436         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 437         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 438
 439         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 440
 441         * gprof.c: added "_mcount" to default_excluded_list.
 442         (main): if output_style==0 and there is either a histogram or a
 443         call-graph, always generate flat and call-graph, no matter what
 444         line_granularity is set to.
 445
 446         * source.c (source_file_lookup_name): if searching for sf->name
 447         fails, try again with filename obtained after stripping off any
 448         partial path from sf->name.
 449
 450         * gprof.h (SRCDEBUG): added.
 451
 452         * search_list.c (search_list_append): directories were added in wrong
 453         order.
 454
 455         * reimplemented selection mechanism from ground up; it is now possible
 456         to accurately control what gets included/excluded in each of the
 457         output styles;  a "symbol-specification" (spec) is the basic means
 458         to select a set of symbols; a spec has the syntax:
 459
 460           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 461           arc == spec/spec.
 462
 463         any of the terminal symbols can be empty, in which case they
 464         match anything (wildcards).  NAME is interpreted as a FILENAME
 465         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 466         with a digit, and as FUNCNAME otherwise.
 467
 468         For example, to get a call-graph display that ignores arcs
 469         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 470         show only arcs into bar() (no matter what the caller),
 471         you'd say "--graph=/bar"; and to get a call-graph without
 472         any arc info, you'd say "--graph=/";  similarly, to
 473         get a flat profile without mcount, you'd say "--no-flat=mcount"
 474         and to get a flat profile that shows includes all functions
 475         you'd say "--flat=""" (i.e., an empty spec)
 476
 477         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 478
 479         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 480
 481         * gmon_out.h: all headers now declared in terms of characters
 482           to avoid getting into trouble with different compilers introducing
 483           different amount of padding; the code already accessed the fields
 484           through bfd functions, so that didn't have to change.
 485
 486         * hist.c (hist_read_rec, hist_write_rec): added support for
 487           collection pc histograms measuring quantities other than time;
 488           the histogram header now includes a field that specifies the
 489           dimension of the quantity measured by the histogram bins
 490           (normally, this is "seconds", but other meaningful dimensions
 491            include such things as "I-cache misses", "instruction issue stalls"
 492            etc.); there is also a field to specify a one-character
 493           abbreviation for the dimension; in the case of time, this would
 494           be 's'; in most other cases it probably would be '1' (not a physical
 495           dimension).
 496
 497         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 498
 499         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 500           has become old_file_version; gmon_io.c now always supports old-style
 501           gmon.out files; it first tries to read gmon.out as a new version
 502           file, if that fails, it tries to read it in the old format;
 503           although not very likely, it is possible for gprof to mistake an
 504           old-style file as a new one (the first 4 bytes would have to
 505           be "gmon"---including the trailing '\0'); in that case, it is
 506           necessary to specify --old-file-version
 507
 508         * gprof.h: removed dependency on SYSV; the code now always uses
 509           strrchr(), memset(), and memcpy() and does not include either
 510           of string.h or strings.h; this should make gprof compile on
 511           any (Unix) system without configuration (per suggestion of
 512           raeburn@cygnus.com)
 513
 514         * gprof.c (usage): fixed location of --new-file-format option.
 515
 516         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 517
 518         * flat_bl.m: removed formfeed at end of file; the form-feed
 519           is now printed cg_print.c only when necessary.
 520
 521         * major rewrite of gprof---too many changes to mention all of
 522           them.  new features:
 523
 524         + -l now requests profiling at the line level (as opposed
 525           to function level); in this mode, gprof creates a "symbol"
 526           (aka name-list entry) for each line of source code, instead
 527            of one per function)
 528
 529         + support for a new gmon.out file format; the new format
 530           consists of a header with a magic and a version number,
 531           followed by a sequence of profile data; profile data
 532           can any of: (a) PC histogram, (b) call-graph arcs, or
 533           (c) basic-block execution counts; the version number makes
 534           it possible to extend gmon.out in a backwards compatible
 535           fashion
 536
 537         + support for tcov style annotated output: if the gmon.out file
 538           contains basic-block execution counts, the user can request
 539           the generation of annotated source files, much like Sun's
 540           tcov used to do
 541
 542         + long options
 543
 544         + new scheme to suppress symbols that aren't function names
 545           (e.g., avoids mistaking a goto label as a function)
 546
 547         + reorganized source code to make it more managable; as a
 548           side effect, gprof now compiles cleanly with "gcc -Wall"
 549
 550         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 551
 552         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 553         final cross-check to determine whether a static symbol should be
 554         considered as a function-name.
 555
 556         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 557
 558         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 559         stdin; this is useful if you wanna keep gmon.out files compressed;
 560         this way you can "gzcat" the compressed file into gprof.
 561
 562         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 563
 564         * basic_blocks.c (bb_annotate_source): added support for creating
 565         .tcov files when option flag_annotate_make_files is TRUE.
 566         (annotate_with_count): all counts less than the minimum count
 567         specified by -m are now annotated with hash-marks.
 568
 569         * gprof.c (main): -A is now followed by a string of option chars.
 570
 571         * basic_blocks.c (annotate_with_count): replaced b->count with
 572         cnt.
 573
 574         * source.c: flag_annotate_source replaced by source_lock_map.
 575
 576         * source.h: source_lock_map added.
 577
 578         * gprof.c (main): new command-line syntax: -S simply specifies
 579         which source-files user is interested in; -A requests annotated
 580         source files and -AA requests that all lines in a source file
 581         are annotated.
 582
 583         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 584
 585         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 586
 587         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 588         so s_lowpc etc. get declared.
 589
 590         * arcs.h (doarcs): created.
 591
 592         * arcs.c: reordered static functions such that they get defined
 593         before use.
 594
 595         * gprof.c (main): added options:
 596            -A: request annotation of all source lines (with -S)
 597            -m: minimum execution count (with default basic-block display)
 598            -N: force new file format (only if BSD_COMPATIBLE is defined)
 599            -S: annotate source file
 600            -t: set table length (with -S)
 601
 602         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 603         source.o time_hist.o
 604
 605         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 606
 607         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 608         on the fact being able to store a long in a double without loss of
 609         precision; this does not hold on machines with 64 bit longs and 64
 610         bit doubles.

 612 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 613
 614         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 615         greater than 0.0.  Suggested by Harold Assink
 616         <carlo@sg.tn.tudelft.nl>.

 618 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 619
 620         * printgprof.c (printprof): Use free, not cfree.
 621         (printgprof, printindex): Ditto.
 622
 623 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 624
 625         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 626         decls extern to keep native HP compiler quiet.
 627
 628 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 629
 630         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 631         __gnu_compiled, for the benefit of systems which add a leading
 632         underscore.
 633
 634 Wed Aug 24 12:49:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 635
 636         * configure.in: Change i386-*-* to i[345]86-*-*.
 637
 638 Sun Jul 10 00:35:31 1994  Ian Dall  (dall@hfrd.dsto.gov.au)
 639
 640         * ns532.c, ns532.h: New Files. ns532 support.
 641
 642         * config/mt-ns532: New File. ns532 support.
 643
 644         * gprof.c: user register int i instead of defaulting the int.
 645         Allows compilation with -Dregister= for debugging.
 646
 647         * configure.in: Add ns532 support.

 658
 659         * configure.bat: [new] build makefile from makefile.in (dos)
 660         * hertz.c: allow static HERTZ (msdos needs it)
 661         * gprof.c: allow target to select "r" or "rb" for fopen
 662         * gprof.c: ignore __gnu_compiled symbols

 666
 667         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 668         so flat_bl.c would make from flat_bl.m file.
 669
 670 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 671
 672         * Makefile.in (install-info): Check for gprof.info in build dir,
 673         fall back to srcdir.  Depend on it.
 674
 675         * gprof.h (TRUE, FALSE): Always use undef before defining them.

 677 Mon Apr  4 23:47:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 678
 679         * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
 680         makes (osf1) in which the value of MACHINE can not be changed.
 681         * config/*.mt: Changed appropriately.
 682
 683 Wed Mar 30 16:12:40 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 684
 685         * gprof.c (getsymtab): Change nosyms to long.  Rename
 686         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
 687         errors from bfd_get_symtab_upper_bound and
 688         bfd_canonicalize_symtab.

 756         bfd-based directories do.
 757         * gprof.h (UNIT):  Replace non-standard 'u_short' by 'unsigned

 788
 789         * gprof.1: updated SYNOPSIS to match actual behavior.
 790
 791 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 792
 793         * gen-c-prog.awk:  New awk script, lightly changed from
 794         previously deleted make-c-prog.awk.  Converts a text file
 795         to a c function that prints that text.
 796         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 797         Inputs to gen-c-prog.awk, containing text describing
 798         gprof output.
 799         * blurbs.c:  Removed.  Use *_bl.c instead.
 800         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 801         from *_bl.m files.  Also, improve *clean rules.
 802         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 805 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 806
 807         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 808         output styles:  The default is similar to the old FSF gprof,
 809         while -T sets the variable bsd_style_output, which causes
 810         output matching Berkeley's gprof.  The biggest differences
 811         are that with the FSF style output, the flat profile comes
 812         before the call graph; numbers come before explanations;
 813         and there is less gratuitous white space.
 814         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 815         variable causes discarding of initial underscores when
 816         printing symbol names.  It is set unless there is a "main"
 817         symbol (without an underscore).
 818         * printfgprof.c:  New function printnameonly(), called
 819         by printname().  It handles stripping of initial '_',
 820         as well as C++ name-demangling.
 821         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 822         It is just as convenient to edit blurbs.c directly.
 823         * Makefile.in:  Removed rule for making blurbs.c.
 824         * blurbs.c:  This is now a true source file (as opposed
 825         to being generated from gprof.callg and gprof.flat).
 826         Change style to use one long string literal, instead of
 827         one literal per output line.  Add FSF-style blurb for call graph.
 828
 829 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 830
 831         * Makefile.in: always create installation directories.

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

 838
 839         * Makefile.in:  removed installation of the now useless
 840         call.{flag,callg} files.
 841
 842         * gprof.1: now uses the standard man macros instead of the new BSD
 843         mandoc macros.
 844
 845 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 846
 847         * configure.in:  Remove host section, expand target section.
 848         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 849         * config/tmake-*:  Remove leftover crud.
 850
 851         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 852         * make-c-prog.awk:  which processes text files into C programs.
 853         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 854         to print blurbs.
 855         (printblurb):  Remove.
 856         * Makefile.in:  Infrastructure to build blurbs.
 857         * pathnames.h:  has been removed.  Gprof now has no filename
 858         dependencies in it.
 859         * gprof.c:  Lint.

 869 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 870
 871         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 872         help in debugging the problem (with -DDEBUG)
 873         * gprof.c: symbol values are now real values, don't add the vma
 874         anymore. (done for solaris; should verify this on other platforms)
 875         * ChangeLog: created.
