 132         * Makefile.in (.m.c): Strip out directory name from function
 133         name.
 134
 135         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 136         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 137         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 138
 139         * vax.c: Don't include vax.h here.
 140
 141 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

 154
 155         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 156         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 157         on info).
 158
 159 Wed Nov  1 15:23:15 1995  Manfred Hollstein KS/EF4A 60/1F/110 #40283  <manfred@lts.sel.alcatel.de>

 166         (mostlyclean):  Don't remove gprof.info*.

 170
 171         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 172
 173         * Makefile.in: Add dependecies for $(OBJS) on header files.
 174
 175         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 176         style output format to make it consistent.
 177         * dummy.c (find_call): Fix typo in error message.
 178
 179 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 180
 181         * Makefile.in (maintainer-clean): New target, synonym for
 182         realclean.
 183
 184 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 185

 195
 196 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 197
 198         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 199         that we're using autoconf.
 200
 201 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 202
 203         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line

 206 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 207
 208         * configure.in: Use changequote around use of [].
 209
 210 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 211
 212         * Makefile.in (distclean, realclean): Remove config.cache and
 213           config.log.
 214
 215 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 216
 217         * Makefile.in (Makefile): Added config.status to dependency list.
 218           (config.status): New target.
 219           (SHELL): New definition.
 220
 221 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 222
 223         * Makefile.in (install): Depend on "all".
 224
 225 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 226
 227         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 228         to match configure script.
 229
 230 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 231
 232         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 233           comment emitted by this script to gen-c-prog.awk.
 234
 235         * Makefile.in, configure.in: Converted to use autoconf.

 239
 240 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 241
 242         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 243
 244         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 245
 246         * All *.c: More cleanup towards GNU format.
 247
 248         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 249         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 250         that bfd_vma is only guaranteed to be at least as big as a pointer.
 251
 252         (GMON_Record_tag): added explicit enumeration values to ensure
 253         compatibility across compilers.
 254
 255         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 256         sizeof(char*).
 257
 258 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 259
 260         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 261         of constructs GNU indent couldn't handle.  Block comments not yet
 262         rewritten in GNU format.
 263
 264         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 265         binutils release.
 266
 267 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 268
 269         * symtab.c (symtab_finalize): ensure globals symbols really
 270         are favored over static ones---even if their name looks less
 271         preferable; this is important for HP-UX; for example, there
 272         is a static label Ltext_something that aliases the global
 273         symbol _start
 274
 275         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 276         output only; also, auto-scaling is now performed based on
 277         per-call, rather than total execution time, which is what it was
 278         meant to be.
 279
 280         * gprof.h (File_Format): new type.
 281
 282         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 283         sync with Cygnus version numbers though...
 284
 285         (long_options): renamed --gmon-info to --file-info, --width added,
 286         renamed --old-file-format to --file-format
 287         (main): dito; also added support to read prof files, but as
 288         mon_out_read() is not implemented, it's #ifdef'd out for now
 289
 290         (usage): update to reflect new options.
 291
 292         * gmon_io.c: replaced "old_file_format" by more general
 293         "file_format" option
 294
 295         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 296
 297         * core.c (core_sym_class): added back check for __gnu_compiled and
 298         ___gnu_compiled for the benefit of systems without
 299         bfd_find_nearest_line() support
 300
 301         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 302         with section-relative addresses
 303
 304         (core_create_function_syms): get_src_info() calls are currently
 305         enabled for OSF/1 only.  It appears to work allright for SunOS
 306         4.1.x as well, but on SPARCs it gets painfully slow with the
 307         current implementation of aout_32_find_nearest_line();
 308         unfortunately, this means that static functions will not have their
 309         filename printed in the call-graph function index; line-level
 310         profiling should still work, but requires some patience
 311
 312         * cg_print.c (cg_print_index): sanitized printing of index when
 313         using FSF-style output; in particular, output width is now controlled
 314         via option --width and the function tries hard to keep columns
 315         aligned even in the presence of (occasional) long names
 316
 317         * NOTES: a first shot at updating the documentation.
 318
 319 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 320
 321         * core.c (core_create_function_syms): fixed computation of min_vma
 322         and max_vma.
 323
 324         * *.c: removed rcsid.
 325
 326 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 327
 328         * Lots of changes from David Mosberger-Tang:
 329
 330         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 331
 332         * gprof.c (main): put parentheses around & within &&.
 333
 334         * basic_blocks.c (bb_read_rec): print warning message (once) when
 335         ignoring basic-block execution counts.
 336
 337         * source.c (source_file_lookup_name): corrected second argument to
 338         strcmp().
 339
 340         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 341         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 342
 343         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 344         supported both for old and new (versioned) gmon.out files.  Old
 345         files are identified as version 0.
 346
 347         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 348         long (instead of 4) because that is what OSF/1 v3.0 uses.
 349
 350         * core.c: minor fixes and debugging info changes.
 351
 352         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 353
 354         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 355         name of the text-section under HP-UX).
 356
 357         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 358         points one past the last sampling bin, so hist_scale should be
 359         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 360         hist_num_bins - 1".
 361
 362         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 363         hist_num_bins.
 364
 365         * configure.in: added alpha-*-*) for per-target config.
 366
 367         * alpha.c, alpha.h: created.
 368
 369         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 370
 371         * core.c (core_create_function_syms, core_create_line_syms):
 372         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 373         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 374         addr) continues to guarantee not to return 0 on any address.  It
 375         also avoids incorrectly crediting the first/last symbol in the
 376         text-space.
 377
 378         * core.c (core_create_line_syms): always create function symbols
 379         first, then merge in line symbols; this is so that if parts of the
 380         program were compiled without -g, function-level symbols are
 381         available still.
 382
 383         * utils.c (print_name_only): support for print_path added.
 384
 385         * symtab.c (cmp_addr): also use is_func flag in comparison.
 386         (symtab_finalize): return immediately when table empty; now
 387         more careful about getting rid of the right duplicate symbol.
 388
 389         * sparc.c (find_call): many fixes---this function was rather
 390         botched in binutils-2.4 already; it should work again.
 391
 392         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 393         not good to rely on get_src_info() to return distinct string
 394         pointers).
 395
 396         * search_list.c (search_list_append): added cast for xmalloc().
 397
 398         * hist.c: added explicit initialization to some of the global
 399         variables; fixed SItab (scales were off by a factor of 10).
 400
 401         * hist.h: include of bfd.h added.
 402
 403         * gprof.c, gprof.h (print_path): added.
 404
 405         * gprof.h (MAX): fixed.
 406
 407         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 408
 409         * gmon_io.c: added some casts to (long) so we can always print as %lx
 410
 411         * core.c (core_get_text_space): fixed to make it work.
 412
 413         * cg_print.c (cg_print_index): added support for print_path option.
 414
 415         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 416
 417         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 418         as some compilers complain (e.g., DEC's OSF/1 compiler)
 419
 420         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 421         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 422
 423         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 424
 425         * gprof.c: added "_mcount" to default_excluded_list.
 426         (main): if output_style==0 and there is either a histogram or a
 427         call-graph, always generate flat and call-graph, no matter what
 428         line_granularity is set to.
 429
 430         * source.c (source_file_lookup_name): if searching for sf->name
 431         fails, try again with filename obtained after stripping off any
 432         partial path from sf->name.
 433
 434         * gprof.h (SRCDEBUG): added.
 435
 436         * search_list.c (search_list_append): directories were added in wrong
 437         order.
 438
 439         * reimplemented selection mechanism from ground up; it is now possible
 440         to accurately control what gets included/excluded in each of the
 441         output styles;  a "symbol-specification" (spec) is the basic means
 442         to select a set of symbols; a spec has the syntax:
 443
 444           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 445           arc == spec/spec.
 446
 447         any of the terminal symbols can be empty, in which case they
 448         match anything (wildcards).  NAME is interpreted as a FILENAME
 449         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 450         with a digit, and as FUNCNAME otherwise.
 451
 452         For example, to get a call-graph display that ignores arcs
 453         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 454         show only arcs into bar() (no matter what the caller),
 455         you'd say "--graph=/bar"; and to get a call-graph without
 456         any arc info, you'd say "--graph=/";  similarly, to
 457         get a flat profile without mcount, you'd say "--no-flat=mcount"
 458         and to get a flat profile that shows includes all functions
 459         you'd say "--flat=""" (i.e., an empty spec)
 460
 461         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 462
 463         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 464
 465         * gmon_out.h: all headers now declared in terms of characters
 466           to avoid getting into trouble with different compilers introducing
 467           different amount of padding; the code already accessed the fields
 468           through bfd functions, so that didn't have to change.
 469
 470         * hist.c (hist_read_rec, hist_write_rec): added support for
 471           collection pc histograms measuring quantities other than time;
 472           the histogram header now includes a field that specifies the
 473           dimension of the quantity measured by the histogram bins
 474           (normally, this is "seconds", but other meaningful dimensions
 475            include such things as "I-cache misses", "instruction issue stalls"
 476            etc.); there is also a field to specify a one-character
 477           abbreviation for the dimension; in the case of time, this would
 478           be 's'; in most other cases it probably would be '1' (not a physical
 479           dimension).
 480
 481         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 482
 483         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 484           has become old_file_version; gmon_io.c now always supports old-style
 485           gmon.out files; it first tries to read gmon.out as a new version
 486           file, if that fails, it tries to read it in the old format;
 487           although not very likely, it is possible for gprof to mistake an
 488           old-style file as a new one (the first 4 bytes would have to
 489           be "gmon"---including the trailing '\0'); in that case, it is
 490           necessary to specify --old-file-version
 491
 492         * gprof.h: removed dependency on SYSV; the code now always uses
 493           strrchr(), memset(), and memcpy() and does not include either
 494           of string.h or strings.h; this should make gprof compile on
 495           any (Unix) system without configuration (per suggestion of
 496           raeburn@cygnus.com)
 497
 498         * gprof.c (usage): fixed location of --new-file-format option.
 499
 500         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 501
 502         * flat_bl.m: removed formfeed at end of file; the form-feed
 503           is now printed cg_print.c only when necessary.
 504
 505         * major rewrite of gprof---too many changes to mention all of
 506           them.  new features:
 507
 508         + -l now requests profiling at the line level (as opposed
 509           to function level); in this mode, gprof creates a "symbol"
 510           (aka name-list entry) for each line of source code, instead
 511            of one per function)
 512
 513         + support for a new gmon.out file format; the new format
 514           consists of a header with a magic and a version number,
 515           followed by a sequence of profile data; profile data
 516           can any of: (a) PC histogram, (b) call-graph arcs, or
 517           (c) basic-block execution counts; the version number makes
 518           it possible to extend gmon.out in a backwards compatible
 519           fashion
 520
 521         + support for tcov style annotated output: if the gmon.out file
 522           contains basic-block execution counts, the user can request
 523           the generation of annotated source files, much like Sun's
 524           tcov used to do
 525
 526         + long options
 527
 528         + new scheme to suppress symbols that aren't function names
 529           (e.g., avoids mistaking a goto label as a function)
 530
 531         + reorganized source code to make it more managable; as a
 532           side effect, gprof now compiles cleanly with "gcc -Wall"
 533
 534         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 535
 536         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 537         final cross-check to determine whether a static symbol should be
 538         considered as a function-name.
 539
 540         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 541
 542         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 543         stdin; this is useful if you wanna keep gmon.out files compressed;
 544         this way you can "gzcat" the compressed file into gprof.
 545
 546         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 547
 548         * basic_blocks.c (bb_annotate_source): added support for creating
 549         .tcov files when option flag_annotate_make_files is TRUE.
 550         (annotate_with_count): all counts less than the minimum count
 551         specified by -m are now annotated with hash-marks.
 552
 553         * gprof.c (main): -A is now followed by a string of option chars.
 554
 555         * basic_blocks.c (annotate_with_count): replaced b->count with
 556         cnt.
 557
 558         * source.c: flag_annotate_source replaced by source_lock_map.
 559
 560         * source.h: source_lock_map added.
 561
 562         * gprof.c (main): new command-line syntax: -S simply specifies
 563         which source-files user is interested in; -A requests annotated
 564         source files and -AA requests that all lines in a source file
 565         are annotated.
 566
 567         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 568
 569         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 570
 571         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 572         so s_lowpc etc. get declared.
 573
 574         * arcs.h (doarcs): created.
 575
 576         * arcs.c: reordered static functions such that they get defined
 577         before use.
 578
 579         * gprof.c (main): added options:
 580            -A: request annotation of all source lines (with -S)
 581            -m: minimum execution count (with default basic-block display)
 582            -N: force new file format (only if BSD_COMPATIBLE is defined)
 583            -S: annotate source file
 584            -t: set table length (with -S)
 585
 586         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 587         source.o time_hist.o
 588
 589         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 590
 591         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 592         on the fact being able to store a long in a double without loss of
 593         precision; this does not hold on machines with 64 bit longs and 64
 594         bit doubles.

 596 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 597
 598         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 599         greater than 0.0.  Suggested by Harold Assink
 600         <carlo@sg.tn.tudelft.nl>.

 602 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 603
 604         * printgprof.c (printprof): Use free, not cfree.
 605         (printgprof, printindex): Ditto.
 606
 607 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 608
 609         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 610         decls extern to keep native HP compiler quiet.
 611
 612 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 613
 614         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 615         __gnu_compiled, for the benefit of systems which add a leading
 616         underscore.
 617
 618 Wed Aug 24 12:49:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)

 622 Sun Jul 10 00:35:31 1994  Ian Dall  (dall@hfrd.dsto.gov.au)
 623
 624         * ns532.c, ns532.h: New Files. ns532 support.
 625
 626         * config/mt-ns532: New File. ns532 support.
 627
 628         * gprof.c: user register int i instead of defaulting the int.
 629         Allows compilation with -Dregister= for debugging.
 630
 631         * configure.in: Add ns532 support.

 650
 651         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 652         so flat_bl.c would make from flat_bl.m file.

 662
 663         * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
 664         makes (osf1) in which the value of MACHINE can not be changed.
 665         * config/*.mt: Changed appropriately.

 667 Wed Mar 30 16:12:40 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 668
 669         * gprof.c (getsymtab): Change nosyms to long.  Rename
 670         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
 671         errors from bfd_get_symtab_upper_bound and
 672         bfd_canonicalize_symtab.

 738         Ads LDFLAGS and use in place of CFLAGS where appropriate.
 739         * configure.in:  Make a sysdep.hlink in the same way other
 740         bfd-based directories do.
 741         * gprof.h (UNIT):  Replace non-standard 'u_short' by 'unsigned
 742         short'.
 743         * gprof.h:  #include sysdep.h instead of a bunch of stuff.
 744         * gprof.c (main):  Fix typo gproff->gprof.

 771 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 772
 773         * gprof.1: updated SYNOPSIS to match actual behavior.
 774
 775 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 776
 777         * gen-c-prog.awk:  New awk script, lightly changed from
 778         previously deleted make-c-prog.awk.  Converts a text file
 779         to a c function that prints that text.
 780         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 781         Inputs to gen-c-prog.awk, containing text describing
 782         gprof output.
 783         * blurbs.c:  Removed.  Use *_bl.c instead.
 784         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 785         from *_bl.m files.  Also, improve *clean rules.
 786         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 790
 791         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 792         output styles:  The default is similar to the old FSF gprof,
 793         while -T sets the variable bsd_style_output, which causes
 794         output matching Berkeley's gprof.  The biggest differences
 795         are that with the FSF style output, the flat profile comes
 796         before the call graph; numbers come before explanations;
 797         and there is less gratuitous white space.
 798         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 799         variable causes discarding of initial underscores when
 800         printing symbol names.  It is set unless there is a "main"
 801         symbol (without an underscore).
 802         * printfgprof.c:  New function printnameonly(), called
 803         by printname().  It handles stripping of initial '_',
 804         as well as C++ name-demangling.
 805         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 806         It is just as convenient to edit blurbs.c directly.
 807         * Makefile.in:  Removed rule for making blurbs.c.
 808         * blurbs.c:  This is now a true source file (as opposed
 809         to being generated from gprof.callg and gprof.flat).
 810         Change style to use one long string literal, instead of
 811         one literal per output line.  Add FSF-style blurb for call graph.
 812
 813 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 814
 815         * Makefile.in: always create installation directories.
 816
 817 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 818
 819         * Makefile.in: change ${MACHINE} to $(MACHINE).

 822
 823         * Makefile.in:  removed installation of the now useless
 824         call.{flag,callg} files.
 825
 826         * gprof.1: now uses the standard man macros instead of the new BSD
 827         mandoc macros.
 828
 829 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 830
 831         * configure.in:  Remove host section, expand target section.
 832         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 833         * config/tmake-*:  Remove leftover crud.
 834
 835         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 836         * make-c-prog.awk:  which processes text files into C programs.
 837         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 838         to print blurbs.
 839         (printblurb):  Remove.
 840         * Makefile.in:  Infrastructure to build blurbs.
 841         * pathnames.h:  has been removed.  Gprof now has no filename
 842         dependencies in it.
 843         * gprof.c:  Lint.

 851         * Makefile.in: added dummy info and install-info targets
 852
 853 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 854
 855         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 856         help in debugging the problem (with -DDEBUG)
 857         * gprof.c: symbol values are now real values, don't add the vma
 858         anymore. (done for solaris; should verify this on other platforms)
 859         * ChangeLog: created.
