 140         * Makefile.in (.m.c): Strip out directory name from function
 141         name.
 142
 143         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
 144         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
 145         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
 146
 147         * vax.c: Don't include vax.h here.
 148
 149 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

 163         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 164         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 165         on info).
 166

 178
 179         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 180
 181         * Makefile.in: Add dependecies for $(OBJS) on header files.
 182
 183         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 184         style output format to make it consistent.
 185         * dummy.c (find_call): Fix typo in error message.
 186
 187 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 188
 189         * Makefile.in (maintainer-clean): New target, synonym for
 190         realclean.
 191
 192 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 193

 203
 204 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 205
 206         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 207         that we're using autoconf.
 208
 209 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 210
 211         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line

 214 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 215
 216         * configure.in: Use changequote around use of [].
 217
 218 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 219
 220         * Makefile.in (distclean, realclean): Remove config.cache and
 221           config.log.
 222
 223 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 224
 225         * Makefile.in (Makefile): Added config.status to dependency list.
 226           (config.status): New target.
 227           (SHELL): New definition.
 228
 229 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 230
 231         * Makefile.in (install): Depend on "all".
 232
 233 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 234
 235         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 236         to match configure script.
 237
 238 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 239
 240         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 241           comment emitted by this script to gen-c-prog.awk.
 242
 243         * Makefile.in, configure.in: Converted to use autoconf.

 247
 248 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 249
 250         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 251
 252         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 253
 254         * All *.c: More cleanup towards GNU format.
 255
 256         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 257         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 258         that bfd_vma is only guaranteed to be at least as big as a pointer.
 259
 260         (GMON_Record_tag): added explicit enumeration values to ensure
 261         compatibility across compilers.
 262
 263         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 264         sizeof(char*).
 265
 266 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 267
 268         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 269         of constructs GNU indent couldn't handle.  Block comments not yet
 270         rewritten in GNU format.
 271
 272         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 273         binutils release.
 274
 275 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 276
 277         * symtab.c (symtab_finalize): ensure globals symbols really
 278         are favored over static ones---even if their name looks less
 279         preferable; this is important for HP-UX; for example, there
 280         is a static label Ltext_something that aliases the global
 281         symbol _start
 282
 283         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 284         output only; also, auto-scaling is now performed based on
 285         per-call, rather than total execution time, which is what it was
 286         meant to be.
 287
 288         * gprof.h (File_Format): new type.
 289
 290         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 291         sync with Cygnus version numbers though...
 292
 293         (long_options): renamed --gmon-info to --file-info, --width added,
 294         renamed --old-file-format to --file-format
 295         (main): dito; also added support to read prof files, but as
 296         mon_out_read() is not implemented, it's #ifdef'd out for now
 297
 298         (usage): update to reflect new options.
 299
 300         * gmon_io.c: replaced "old_file_format" by more general
 301         "file_format" option
 302
 303         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 304
 305         * core.c (core_sym_class): added back check for __gnu_compiled and
 306         ___gnu_compiled for the benefit of systems without
 307         bfd_find_nearest_line() support
 308
 309         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 310         with section-relative addresses
 311
 312         (core_create_function_syms): get_src_info() calls are currently
 313         enabled for OSF/1 only.  It appears to work allright for SunOS
 314         4.1.x as well, but on SPARCs it gets painfully slow with the
 315         current implementation of aout_32_find_nearest_line();
 316         unfortunately, this means that static functions will not have their
 317         filename printed in the call-graph function index; line-level
 318         profiling should still work, but requires some patience
 319
 320         * cg_print.c (cg_print_index): sanitized printing of index when
 321         using FSF-style output; in particular, output width is now controlled
 322         via option --width and the function tries hard to keep columns
 323         aligned even in the presence of (occasional) long names
 324
 325         * NOTES: a first shot at updating the documentation.
 326
 327 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 328
 329         * core.c (core_create_function_syms): fixed computation of min_vma
 330         and max_vma.
 331
 332         * *.c: removed rcsid.
 333
 334 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 335
 336         * Lots of changes from David Mosberger-Tang:
 337
 338         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 339
 340         * gprof.c (main): put parentheses around & within &&.
 341
 342         * basic_blocks.c (bb_read_rec): print warning message (once) when
 343         ignoring basic-block execution counts.
 344
 345         * source.c (source_file_lookup_name): corrected second argument to
 346         strcmp().
 347
 348         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 349         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 350
 351         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 352         supported both for old and new (versioned) gmon.out files.  Old
 353         files are identified as version 0.
 354
 355         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 356         long (instead of 4) because that is what OSF/1 v3.0 uses.
 357
 358         * core.c: minor fixes and debugging info changes.
 359
 360         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 361
 362         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 363         name of the text-section under HP-UX).
 364
 365         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 366         points one past the last sampling bin, so hist_scale should be
 367         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 368         hist_num_bins - 1".
 369
 370         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 371         hist_num_bins.
 372
 373         * configure.in: added alpha-*-*) for per-target config.
 374
 375         * alpha.c, alpha.h: created.
 376
 377         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 378
 379         * core.c (core_create_function_syms, core_create_line_syms):
 380         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 381         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 382         addr) continues to guarantee not to return 0 on any address.  It
 383         also avoids incorrectly crediting the first/last symbol in the
 384         text-space.
 385
 386         * core.c (core_create_line_syms): always create function symbols
 387         first, then merge in line symbols; this is so that if parts of the
 388         program were compiled without -g, function-level symbols are
 389         available still.
 390
 391         * utils.c (print_name_only): support for print_path added.
 392
 393         * symtab.c (cmp_addr): also use is_func flag in comparison.
 394         (symtab_finalize): return immediately when table empty; now
 395         more careful about getting rid of the right duplicate symbol.
 396
 397         * sparc.c (find_call): many fixes---this function was rather
 398         botched in binutils-2.4 already; it should work again.
 399
 400         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 401         not good to rely on get_src_info() to return distinct string
 402         pointers).
 403
 404         * search_list.c (search_list_append): added cast for xmalloc().
 405
 406         * hist.c: added explicit initialization to some of the global
 407         variables; fixed SItab (scales were off by a factor of 10).
 408
 409         * hist.h: include of bfd.h added.
 410
 411         * gprof.c, gprof.h (print_path): added.
 412
 413         * gprof.h (MAX): fixed.
 414
 415         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 416
 417         * gmon_io.c: added some casts to (long) so we can always print as %lx
 418
 419         * core.c (core_get_text_space): fixed to make it work.
 420
 421         * cg_print.c (cg_print_index): added support for print_path option.
 422
 423         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 424
 425         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 426         as some compilers complain (e.g., DEC's OSF/1 compiler)
 427
 428         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 429         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 430
 431         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 432
 433         * gprof.c: added "_mcount" to default_excluded_list.
 434         (main): if output_style==0 and there is either a histogram or a
 435         call-graph, always generate flat and call-graph, no matter what
 436         line_granularity is set to.
 437
 438         * source.c (source_file_lookup_name): if searching for sf->name
 439         fails, try again with filename obtained after stripping off any
 440         partial path from sf->name.
 441
 442         * gprof.h (SRCDEBUG): added.
 443
 444         * search_list.c (search_list_append): directories were added in wrong
 445         order.
 446
 447         * reimplemented selection mechanism from ground up; it is now possible
 448         to accurately control what gets included/excluded in each of the
 449         output styles;  a "symbol-specification" (spec) is the basic means
 450         to select a set of symbols; a spec has the syntax:
 451
 452           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 453           arc == spec/spec.
 454
 455         any of the terminal symbols can be empty, in which case they
 456         match anything (wildcards).  NAME is interpreted as a FILENAME
 457         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 458         with a digit, and as FUNCNAME otherwise.
 459
 460         For example, to get a call-graph display that ignores arcs
 461         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 462         show only arcs into bar() (no matter what the caller),
 463         you'd say "--graph=/bar"; and to get a call-graph without
 464         any arc info, you'd say "--graph=/";  similarly, to
 465         get a flat profile without mcount, you'd say "--no-flat=mcount"
 466         and to get a flat profile that shows includes all functions
 467         you'd say "--flat=""" (i.e., an empty spec)
 468
 469         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 470
 471         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 472
 473         * gmon_out.h: all headers now declared in terms of characters
 474           to avoid getting into trouble with different compilers introducing
 475           different amount of padding; the code already accessed the fields
 476           through bfd functions, so that didn't have to change.
 477
 478         * hist.c (hist_read_rec, hist_write_rec): added support for
 479           collection pc histograms measuring quantities other than time;
 480           the histogram header now includes a field that specifies the
 481           dimension of the quantity measured by the histogram bins
 482           (normally, this is "seconds", but other meaningful dimensions
 483            include such things as "I-cache misses", "instruction issue stalls"
 484            etc.); there is also a field to specify a one-character
 485           abbreviation for the dimension; in the case of time, this would
 486           be 's'; in most other cases it probably would be '1' (not a physical
 487           dimension).
 488
 489         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 490
 491         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 492           has become old_file_version; gmon_io.c now always supports old-style
 493           gmon.out files; it first tries to read gmon.out as a new version
 494           file, if that fails, it tries to read it in the old format;
 495           although not very likely, it is possible for gprof to mistake an
 496           old-style file as a new one (the first 4 bytes would have to
 497           be "gmon"---including the trailing '\0'); in that case, it is
 498           necessary to specify --old-file-version
 499
 500         * gprof.h: removed dependency on SYSV; the code now always uses
 501           strrchr(), memset(), and memcpy() and does not include either
 502           of string.h or strings.h; this should make gprof compile on
 503           any (Unix) system without configuration (per suggestion of
 504           raeburn@cygnus.com)
 505
 506         * gprof.c (usage): fixed location of --new-file-format option.
 507
 508         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 509
 510         * flat_bl.m: removed formfeed at end of file; the form-feed
 511           is now printed cg_print.c only when necessary.
 512
 513         * major rewrite of gprof---too many changes to mention all of
 514           them.  new features:
 515
 516         + -l now requests profiling at the line level (as opposed
 517           to function level); in this mode, gprof creates a "symbol"
 518           (aka name-list entry) for each line of source code, instead
 519            of one per function)
 520
 521         + support for a new gmon.out file format; the new format
 522           consists of a header with a magic and a version number,
 523           followed by a sequence of profile data; profile data
 524           can any of: (a) PC histogram, (b) call-graph arcs, or
 525           (c) basic-block execution counts; the version number makes
 526           it possible to extend gmon.out in a backwards compatible
 527           fashion
 528
 529         + support for tcov style annotated output: if the gmon.out file
 530           contains basic-block execution counts, the user can request
 531           the generation of annotated source files, much like Sun's
 532           tcov used to do
 533
 534         + long options
 535
 536         + new scheme to suppress symbols that aren't function names
 537           (e.g., avoids mistaking a goto label as a function)
 538
 539         + reorganized source code to make it more managable; as a
 540           side effect, gprof now compiles cleanly with "gcc -Wall"
 541
 542         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 543
 544         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 545         final cross-check to determine whether a static symbol should be
 546         considered as a function-name.
 547
 548         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 549
 550         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 551         stdin; this is useful if you wanna keep gmon.out files compressed;
 552         this way you can "gzcat" the compressed file into gprof.
 553
 554         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 555
 556         * basic_blocks.c (bb_annotate_source): added support for creating
 557         .tcov files when option flag_annotate_make_files is TRUE.
 558         (annotate_with_count): all counts less than the minimum count
 559         specified by -m are now annotated with hash-marks.
 560
 561         * gprof.c (main): -A is now followed by a string of option chars.
 562
 563         * basic_blocks.c (annotate_with_count): replaced b->count with
 564         cnt.
 565
 566         * source.c: flag_annotate_source replaced by source_lock_map.
 567
 568         * source.h: source_lock_map added.
 569
 570         * gprof.c (main): new command-line syntax: -S simply specifies
 571         which source-files user is interested in; -A requests annotated
 572         source files and -AA requests that all lines in a source file
 573         are annotated.
 574
 575         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 576
 577         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 578
 579         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 580         so s_lowpc etc. get declared.
 581
 582         * arcs.h (doarcs): created.
 583
 584         * arcs.c: reordered static functions such that they get defined
 585         before use.
 586
 587         * gprof.c (main): added options:
 588            -A: request annotation of all source lines (with -S)
 589            -m: minimum execution count (with default basic-block display)
 590            -N: force new file format (only if BSD_COMPATIBLE is defined)
 591            -S: annotate source file
 592            -t: set table length (with -S)
 593
 594         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 595         source.o time_hist.o
 596
 597         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 598
 599         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 600         on the fact being able to store a long in a double without loss of
 601         precision; this does not hold on machines with 64 bit longs and 64
 602         bit doubles.

 604 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 605
 606         * printgprof.c (flatprofheader): Always set totime to 1.0 if not
 607         greater than 0.0.  Suggested by Harold Assink
 608         <carlo@sg.tn.tudelft.nl>.

 610 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 611
 612         * printgprof.c (printprof): Use free, not cfree.
 613         (printgprof, printindex): Ditto.
 614
 615 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 616
 617         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 618         decls extern to keep native HP compiler quiet.
 619
 620 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 621
 622         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 623         __gnu_compiled, for the benefit of systems which add a leading
 624         underscore.
 625

 630 Sun Jul 10 00:35:31 1994  Ian Dall  (dall@hfrd.dsto.gov.au)
 631
 632         * ns532.c, ns532.h: New Files. ns532 support.
 633
 634         * config/mt-ns532: New File. ns532 support.
 635
 636         * gprof.c: user register int i instead of defaulting the int.
 637         Allows compilation with -Dregister= for debugging.
 638
 639         * configure.in: Add ns532 support.

 658
 659         * Makefile.in (.m.c:):  Added .SUFFIXES : .m
 660         so flat_bl.c would make from flat_bl.m file.
 661
 662 Thu May  5 19:23:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
 663

 665         fall back to srcdir.  Depend on it.
 666
 667         * gprof.h (TRUE, FALSE): Always use undef before defining them.

 670
 671         * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
 672         makes (osf1) in which the value of MACHINE can not be changed.
 673         * config/*.mt: Changed appropriately.

 675 Wed Mar 30 16:12:40 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 676
 677         * gprof.c (getsymtab): Change nosyms to long.  Rename
 678         get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
 679         errors from bfd_get_symtab_upper_bound and
 680         bfd_canonicalize_symtab.

 716
 717         * gmon.h, gprof.h: structs of chars used to hold external
 718         representations.

 744
 745         * M Makefile.in:  Add -g to CFLAGS.
 746         Ads LDFLAGS and use in place of CFLAGS where appropriate.
 747         * configure.in:  Make a sysdep.hlink in the same way other
 748         bfd-based directories do.
 749         * gprof.h (UNIT):  Replace non-standard 'u_short' by 'unsigned
 750         short'.
 751         * gprof.h:  #include sysdep.h instead of a bunch of stuff.
 752         * gprof.c (main):  Fix typo gproff->gprof.

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

 797 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 798
 799         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 800         output styles:  The default is similar to the old FSF gprof,
 801         while -T sets the variable bsd_style_output, which causes
 802         output matching Berkeley's gprof.  The biggest differences
 803         are that with the FSF style output, the flat profile comes
 804         before the call graph; numbers come before explanations;
 805         and there is less gratuitous white space.
 806         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 807         variable causes discarding of initial underscores when
 808         printing symbol names.  It is set unless there is a "main"
 809         symbol (without an underscore).
 810         * printfgprof.c:  New function printnameonly(), called
 811         by printname().  It handles stripping of initial '_',
 812         as well as C++ name-demangling.
 813         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 814         It is just as convenient to edit blurbs.c directly.
 815         * Makefile.in:  Removed rule for making blurbs.c.
 816         * blurbs.c:  This is now a true source file (as opposed
 817         to being generated from gprof.callg and gprof.flat).
 818         Change style to use one long string literal, instead of
 819         one literal per output line.  Add FSF-style blurb for call graph.
 820
 821 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 822
 823         * Makefile.in: always create installation directories.
 824
 825 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 826
 827         * Makefile.in: change ${MACHINE} to $(MACHINE).

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

 860
 861 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 862
 863         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 864         help in debugging the problem (with -DDEBUG)
 865         * gprof.c: symbol values are now real values, don't add the vma
 866         anymore. (done for solaris; should verify this on other platforms)
 867         * ChangeLog: created.
