   2
   3         * core.c (core_sym_class): Ignore symbols without BSF_FUNCTION
   4         set if ignore_non_function is set.
   5         * gprof.h (ignore_non_functions): Declare.
   6         * gprof.c (ignore_non_functions): Define.
   7         (long_options): Add "ignore-non-functions".
   8         (usage): Add new options.
   9         (main): Recognize "-D" and "--ignore-non-functions" option.

  11 Tue Nov 21 13:24:39 1995  Ken Raeburn  <raeburn@cygnus.com>
  12
  13         * Makefile.in (.m.c): Strip out directory name from function
  14         name.
  15
  16         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
  17         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
  18         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
  19
  20         * vax.c: Don't include vax.h here.
  21
  22 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

  33
  34 Wed Nov  1 12:51:21 1995  Per Bothner  <bothner@kalessin.cygnus.com>
  35
  36         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
  37         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
  38         on info).
  39
  40 Wed Nov  1 15:23:15 1995  Manfred Hollstein KS/EF4A 60/1F/110 #40283  <manfred@lts.sel.alcatel.de>
  41
  42         * sym_ids.c: Include <ctype.h>.
  43
  44 Wed Oct 25 13:24:31 1995  Per Bothner  <bothner@kalessin.cygnus.com>
  45
  46         * Makefile.in (diststuff):  Also make info.
  47         (mostlyclean):  Don't remove gprof.info*.
  48         (maintainer-clean realclean):  Also remove *.info*.

  51
  52         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
  53
  54         * Makefile.in: Add dependecies for $(OBJS) on header files.
  55
  56         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
  57         style output format to make it consistent.
  58         * dummy.c (find_call): Fix typo in error message.
  59
  60 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
  61
  62         * Makefile.in (maintainer-clean): New target, synonym for
  63         realclean.
  64
  65 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
  66
  67         * Makefile.in (install): Don't install in $(tooldir).
  68
  69 Fri Aug 25 15:30:05 1995  Ken Raeburn  <raeburn@cygnus.com>
  70
  71         NS32K changes from Ian Dall:
  72         * configure.in: Use ns32k, not ns532.
  73         * ns532.c: Include symtab.h.
  74         (find_call): Renamed from findcall.  Print a message.
  75         * ns532.h: Remove dummy.h comments.
  76
  77 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
  78
  79         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
  80         that we're using autoconf.
  81
  82 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
  83
  84         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
  85         to proper type of "unsigned int *".
  86
  87 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
  88
  89         * configure.in: Use changequote around use of [].
  90
  91 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  92
  93         * Makefile.in (distclean, realclean): Remove config.cache and
  94           config.log.
  95
  96 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
  97
  98         * Makefile.in (Makefile): Added config.status to dependency list.
  99           (config.status): New target.
 100           (SHELL): New definition.
 101
 102 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 103
 104         * Makefile.in (install): Depend on "all".
 105
 106 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 107
 108         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 109         to match configure script.
 110
 111 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 112
 113         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 114           comment emitted by this script to gen-c-prog.awk.
 115
 116         * Makefile.in, configure.in: Converted to use autoconf.
 117         * configure: New file, generated with autoconf 2.3.
 118         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 119           mt-tahoe, mt-vax}: Removed.
 120
 121 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 122
 123         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 124
 125         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 126
 127         * All *.c: More cleanup towards GNU format.
 128
 129         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 130         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 131         that bfd_vma is only guaranteed to be at least as big as a pointer.
 132
 133         (GMON_Record_tag): added explicit enumeration values to ensure
 134         compatibility across compilers.
 135
 136         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 137         sizeof(char*).
 138
 139 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 140
 141         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 142         of constructs GNU indent couldn't handle.  Block comments not yet
 143         rewritten in GNU format.
 144
 145         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 146         binutils release.
 147
 148 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 149
 150         * symtab.c (symtab_finalize): ensure globals symbols really
 151         are favored over static ones---even if their name looks less
 152         preferable; this is important for HP-UX; for example, there
 153         is a static label Ltext_something that aliases the global
 154         symbol _start
 155
 156         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 157         output only; also, auto-scaling is now performed based on
 158         per-call, rather than total execution time, which is what it was
 159         meant to be.
 160
 161         * gprof.h (File_Format): new type.
 162
 163         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 164         sync with Cygnus version numbers though...
 165
 166         (long_options): renamed --gmon-info to --file-info, --width added,
 167         renamed --old-file-format to --file-format
 168         (main): dito; also added support to read prof files, but as
 169         mon_out_read() is not implemented, it's #ifdef'd out for now
 170
 171         (usage): update to reflect new options.
 172
 173         * gmon_io.c: replaced "old_file_format" by more general
 174         "file_format" option
 175
 176         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 177
 178         * core.c (core_sym_class): added back check for __gnu_compiled and
 179         ___gnu_compiled for the benefit of systems without
 180         bfd_find_nearest_line() support
 181
 182         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 183         with section-relative addresses
 184
 185         (core_create_function_syms): get_src_info() calls are currently
 186         enabled for OSF/1 only.  It appears to work allright for SunOS
 187         4.1.x as well, but on SPARCs it gets painfully slow with the
 188         current implementation of aout_32_find_nearest_line();
 189         unfortunately, this means that static functions will not have their
 190         filename printed in the call-graph function index; line-level
 191         profiling should still work, but requires some patience
 192
 193         * cg_print.c (cg_print_index): sanitized printing of index when
 194         using FSF-style output; in particular, output width is now controlled
 195         via option --width and the function tries hard to keep columns
 196         aligned even in the presence of (occasional) long names
 197
 198         * NOTES: a first shot at updating the documentation.
 199
 200 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 201
 202         * core.c (core_create_function_syms): fixed computation of min_vma
 203         and max_vma.
 204
 205         * *.c: removed rcsid.
 206
 207 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 208
 209         * Lots of changes from David Mosberger-Tang:
 210
 211         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 212
 213         * gprof.c (main): put parentheses around & within &&.
 214
 215         * basic_blocks.c (bb_read_rec): print warning message (once) when
 216         ignoring basic-block execution counts.
 217
 218         * source.c (source_file_lookup_name): corrected second argument to
 219         strcmp().
 220
 221         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 222         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 223
 224         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 225         supported both for old and new (versioned) gmon.out files.  Old
 226         files are identified as version 0.
 227
 228         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 229         long (instead of 4) because that is what OSF/1 v3.0 uses.
 230
 231         * core.c: minor fixes and debugging info changes.
 232
 233         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 234
 235         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 236         name of the text-section under HP-UX).
 237
 238         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 239         points one past the last sampling bin, so hist_scale should be
 240         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 241         hist_num_bins - 1".
 242
 243         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 244         hist_num_bins.
 245
 246         * configure.in: added alpha-*-*) for per-target config.
 247
 248         * alpha.c, alpha.h: created.
 249
 250         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 251
 252         * core.c (core_create_function_syms, core_create_line_syms):
 253         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 254         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 255         addr) continues to guarantee not to return 0 on any address.  It
 256         also avoids incorrectly crediting the first/last symbol in the
 257         text-space.
 258
 259         * core.c (core_create_line_syms): always create function symbols
 260         first, then merge in line symbols; this is so that if parts of the
 261         program were compiled without -g, function-level symbols are
 262         available still.
 263
 264         * utils.c (print_name_only): support for print_path added.
 265
 266         * symtab.c (cmp_addr): also use is_func flag in comparison.
 267         (symtab_finalize): return immediately when table empty; now
 268         more careful about getting rid of the right duplicate symbol.
 269
 270         * sparc.c (find_call): many fixes---this function was rather
 271         botched in binutils-2.4 already; it should work again.
 272
 273         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 274         not good to rely on get_src_info() to return distinct string
 275         pointers).
 276
 277         * search_list.c (search_list_append): added cast for xmalloc().
 278
 279         * hist.c: added explicit initialization to some of the global
 280         variables; fixed SItab (scales were off by a factor of 10).
 281
 282         * hist.h: include of bfd.h added.
 283
 284         * gprof.c, gprof.h (print_path): added.
 285
 286         * gprof.h (MAX): fixed.
 287
 288         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 289
 290         * gmon_io.c: added some casts to (long) so we can always print as %lx
 291
 292         * core.c (core_get_text_space): fixed to make it work.
 293
 294         * cg_print.c (cg_print_index): added support for print_path option.
 295
 296         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 297
 298         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 299         as some compilers complain (e.g., DEC's OSF/1 compiler)
 300
 301         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 302         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 303
 304         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 305
 306         * gprof.c: added "_mcount" to default_excluded_list.
 307         (main): if output_style==0 and there is either a histogram or a
 308         call-graph, always generate flat and call-graph, no matter what
 309         line_granularity is set to.
 310
 311         * source.c (source_file_lookup_name): if searching for sf->name
 312         fails, try again with filename obtained after stripping off any
 313         partial path from sf->name.
 314
 315         * gprof.h (SRCDEBUG): added.
 316
 317         * search_list.c (search_list_append): directories were added in wrong
 318         order.
 319
 320         * reimplemented selection mechanism from ground up; it is now possible
 321         to accurately control what gets included/excluded in each of the
 322         output styles;  a "symbol-specification" (spec) is the basic means
 323         to select a set of symbols; a spec has the syntax:
 324
 325           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 326           arc == spec/spec.
 327
 328         any of the terminal symbols can be empty, in which case they
 329         match anything (wildcards).  NAME is interpreted as a FILENAME
 330         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 331         with a digit, and as FUNCNAME otherwise.
 332
 333         For example, to get a call-graph display that ignores arcs
 334         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 335         show only arcs into bar() (no matter what the caller),
 336         you'd say "--graph=/bar"; and to get a call-graph without
 337         any arc info, you'd say "--graph=/";  similarly, to
 338         get a flat profile without mcount, you'd say "--no-flat=mcount"
 339         and to get a flat profile that shows includes all functions
 340         you'd say "--flat=""" (i.e., an empty spec)
 341
 342         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 343
 344         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 345
 346         * gmon_out.h: all headers now declared in terms of characters
 347           to avoid getting into trouble with different compilers introducing
 348           different amount of padding; the code already accessed the fields
 349           through bfd functions, so that didn't have to change.
 350
 351         * hist.c (hist_read_rec, hist_write_rec): added support for
 352           collection pc histograms measuring quantities other than time;
 353           the histogram header now includes a field that specifies the
 354           dimension of the quantity measured by the histogram bins
 355           (normally, this is "seconds", but other meaningful dimensions
 356            include such things as "I-cache misses", "instruction issue stalls"
 357            etc.); there is also a field to specify a one-character
 358           abbreviation for the dimension; in the case of time, this would
 359           be 's'; in most other cases it probably would be '1' (not a physical
 360           dimension).

 364         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 365           has become old_file_version; gmon_io.c now always supports old-style
 366           gmon.out files; it first tries to read gmon.out as a new version
 367           file, if that fails, it tries to read it in the old format;
 368           although not very likely, it is possible for gprof to mistake an
 369           old-style file as a new one (the first 4 bytes would have to
 370           be "gmon"---including the trailing '\0'); in that case, it is
 371           necessary to specify --old-file-version
 372
 373         * gprof.h: removed dependency on SYSV; the code now always uses
 374           strrchr(), memset(), and memcpy() and does not include either
 375           of string.h or strings.h; this should make gprof compile on
 376           any (Unix) system without configuration (per suggestion of
 377           raeburn@cygnus.com)
 378
 379         * gprof.c (usage): fixed location of --new-file-format option.
 380
 381         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 382
 383         * flat_bl.m: removed formfeed at end of file; the form-feed
 384           is now printed cg_print.c only when necessary.
 385
 386         * major rewrite of gprof---too many changes to mention all of
 387           them.  new features:
 388
 389         + -l now requests profiling at the line level (as opposed
 390           to function level); in this mode, gprof creates a "symbol"
 391           (aka name-list entry) for each line of source code, instead
 392            of one per function)
 393
 394         + support for a new gmon.out file format; the new format
 395           consists of a header with a magic and a version number,
 396           followed by a sequence of profile data; profile data
 397           can any of: (a) PC histogram, (b) call-graph arcs, or
 398           (c) basic-block execution counts; the version number makes
 399           it possible to extend gmon.out in a backwards compatible
 400           fashion
 401
 402         + support for tcov style annotated output: if the gmon.out file
 403           contains basic-block execution counts, the user can request
 404           the generation of annotated source files, much like Sun's
 405           tcov used to do
 406
 407         + long options
 408
 409         + new scheme to suppress symbols that aren't function names
 410           (e.g., avoids mistaking a goto label as a function)
 411
 412         + reorganized source code to make it more managable; as a
 413           side effect, gprof now compiles cleanly with "gcc -Wall"
 414
 415         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 416
 417         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 418         final cross-check to determine whether a static symbol should be
 419         considered as a function-name.
 420
 421         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 422
 423         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 424         stdin; this is useful if you wanna keep gmon.out files compressed;
 425         this way you can "gzcat" the compressed file into gprof.
 426
 427         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 428
 429         * basic_blocks.c (bb_annotate_source): added support for creating
 430         .tcov files when option flag_annotate_make_files is TRUE.
 431         (annotate_with_count): all counts less than the minimum count
 432         specified by -m are now annotated with hash-marks.
 433
 434         * gprof.c (main): -A is now followed by a string of option chars.
 435
 436         * basic_blocks.c (annotate_with_count): replaced b->count with
 437         cnt.
 438
 439         * source.c: flag_annotate_source replaced by source_lock_map.
 440
 441         * source.h: source_lock_map added.
 442
 443         * gprof.c (main): new command-line syntax: -S simply specifies
 444         which source-files user is interested in; -A requests annotated
 445         source files and -AA requests that all lines in a source file
 446         are annotated.
 447
 448         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 449
 450         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 451
 452         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 453         so s_lowpc etc. get declared.
 454
 455         * arcs.h (doarcs): created.
 456
 457         * arcs.c: reordered static functions such that they get defined
 458         before use.
 459
 460         * gprof.c (main): added options:
 461            -A: request annotation of all source lines (with -S)
 462            -m: minimum execution count (with default basic-block display)
 463            -N: force new file format (only if BSD_COMPATIBLE is defined)
 464            -S: annotate source file
 465            -t: set table length (with -S)
 466
 467         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 468         source.o time_hist.o
 469
 470         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 471
 472         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 473         on the fact being able to store a long in a double without loss of
 474         precision; this does not hold on machines with 64 bit longs and 64
 475         bit doubles.

 477 Fri Oct 21 18:58:02 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>

 480         greater than 0.0.  Suggested by Harold Assink
 481         <carlo@sg.tn.tudelft.nl>.

 483 Fri Sep 23 15:06:45 1994  Ken Raeburn  <raeburn@cujo.cygnus.com>
 484
 485         * printgprof.c (printprof): Use free, not cfree.
 486         (printgprof, printindex): Ditto.

 488 Thu Sep  1 10:40:45 1994  Jeff Law  (law@snake.cs.utah.edu)
 489
 490         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 491         decls extern to keep native HP compiler quiet.
 492
 493 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)
 494
 495         * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
 496         __gnu_compiled, for the benefit of systems which add a leading
 497         underscore.

 589
 590         * gmon.h, gprof.h: structs of chars used to hold external

 642         and realloc to PTR.
 643
 644 Wed Feb  3 13:55:33 1993  Jeffrey Osier  (jeffrey@fowanton.cygnus.com)
 645
 646         * Makefile.in: created info, install-info, dvi
 647
 648 Wed Jan  6 00:58:09 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)
 649
 650         * Makefile.in: fix install rule for $(PROG)
 651
 652 Fri Oct  9 11:25:41 1992  Mark Eichin  (eichin@cygnus.com)
 653
 654         * gprof.1: updated SYNOPSIS to match actual behavior.
 655
 656 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 657
 658         * gen-c-prog.awk:  New awk script, lightly changed from
 659         previously deleted make-c-prog.awk.  Converts a text file
 660         to a c function that prints that text.
 661         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 662         Inputs to gen-c-prog.awk, containing text describing
 663         gprof output.
 664         * blurbs.c:  Removed.  Use *_bl.c instead.
 665         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 666         from *_bl.m files.  Also, improve *clean rules.
 667         * printgprof.c (printgprof):  Usw new function names from *_bl.c.
 668
 669
 670 Sun Aug 30 19:54:53 1992  Per Bothner  (bothner@rtl.cygnus.com)
 671
 672         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 673         output styles:  The default is similar to the old FSF gprof,
 674         while -T sets the variable bsd_style_output, which causes
 675         output matching Berkeley's gprof.  The biggest differences
 676         are that with the FSF style output, the flat profile comes
 677         before the call graph; numbers come before explanations;
 678         and there is less gratuitous white space.
 679         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 680         variable causes discarding of initial underscores when
 681         printing symbol names.  It is set unless there is a "main"
 682         symbol (without an underscore).
 683         * printfgprof.c:  New function printnameonly(), called
 684         by printname().  It handles stripping of initial '_',
 685         as well as C++ name-demangling.
 686         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 687         It is just as convenient to edit blurbs.c directly.
 688         * Makefile.in:  Removed rule for making blurbs.c.
 689         * blurbs.c:  This is now a true source file (as opposed
 690         to being generated from gprof.callg and gprof.flat).
 691         Change style to use one long string literal, instead of
 692         one literal per output line.  Add FSF-style blurb for call graph.
 693
 694 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 695
 696         * Makefile.in: always create installation directories.

 698 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 699
 700         * Makefile.in: change ${MACHINE} to $(MACHINE).
 701
 702 Sun Jul 19 17:34:01 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)
 703
 704         * Makefile.in:  removed installation of the now useless
 705         call.{flag,callg} files.
 706
 707         * gprof.1: now uses the standard man macros instead of the new BSD
 708         mandoc macros.
 709
 710 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 711
 712         * configure.in:  Remove host section, expand target section.
 713         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 714         * config/tmake-*:  Remove leftover crud.
 715
