   2
   3         * cg_print.c (cg_print_function_ordering): Fix __GNUC__ misspelled
   4         as __GNU_C__.

  25         BFDLIB and HLDFLAGS and substitute them.
  26         * configure: Rebuild.
  27         * Makefile.in (LIBS): Use @BFDLIB@.

  59         mappings.
  60         * symtab.h (struct sym): New fields "mapped", "has_been_placed",
  61         "nuses", "prev".
  62         * cg_print.c (cmp_arc_count): New function for sorting arcs.
  63         (cmp_fun_nuses): Likewise for functions.

  71
  72         * core.c (core_sym_class): Ignore symbols without BSF_FUNCTION
  73         set if ignore_non_function is set.

  81
  82         * Makefile.in (.m.c): Strip out directory name from function
  83         name.
  84
  85         * hist.c (scale_and_align_entries): Don't use DEFUN_VOID.  Do
  86         UNITS_TO_CODE adjustment unconditionally; compiler can optimize
  87         away zero-offset case.  Refer to scaled_addr, not aligned_addr.
  88
  89         * vax.c: Don't include vax.h here.
  90
  91 Thu Nov 16 03:41:37 1995  Ken Raeburn  <raeburn@cygnus.com>

 103 Wed Nov  1 12:51:21 1995  Per Bothner  <bothner@kalessin.cygnus.com>
 104
 105         * Makefile.in (DISTSTUFF):  Rename to GEN_FILES, to avoid confusion.
 106         (all):  Depend on $(GEN_FILES), not diststuff (which also depends
 107         on info).
 108
 109 Wed Nov  1 15:23:15 1995  Manfred Hollstein KS/EF4A 60/1F/110 #40283  <manfred@lts.sel.alcatel.de>

 116         (mostlyclean):  Don't remove gprof.info*.
 117         (maintainer-clean realclean):  Also remove *.info*.
 118

 120
 121         Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
 122
 123         * Makefile.in: Add dependecies for $(OBJS) on header files.
 124
 125         * cg_print.c (print_cycle, print_members, cg_print_index): Fix new
 126         style output format to make it consistent.
 127         * dummy.c (find_call): Fix typo in error message.
 128
 129 Wed Sep 20 13:21:02 1995  Ian Lance Taylor  <ian@cygnus.com>
 130
 131         * Makefile.in (maintainer-clean): New target, synonym for
 132         realclean.
 133
 134 Fri Sep  8 14:38:08 1995  Ian Lance Taylor  <ian@cygnus.com>
 135
 136         * Makefile.in (install): Don't install in $(tooldir).
 137
 138 Fri Aug 25 15:30:05 1995  Ken Raeburn  <raeburn@cygnus.com>
 139
 140         NS32K changes from Ian Dall:
 141         * configure.in: Use ns32k, not ns532.
 142         * ns532.c: Include symtab.h.
 143         (find_call): Renamed from findcall.  Print a message.
 144         * ns532.h: Remove dummy.h comments.
 145
 146 Tue Aug 22 10:00:45 1995  Jeffrey A. Law  <law@rtl.cygnus.com>
 147
 148         * Makefile.in (install): Remove "brokensed" hack, unnecessary now
 149         that we're using autoconf.
 150
 151 Wed Jul 19 18:46:13 1995  Fred Fish  <fnf@cygnus.com>
 152
 153         * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
 154         to proper type of "unsigned int *".
 155
 156 Fri Jun 16 15:29:36 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 157
 158         * configure.in: Use changequote around use of [].
 159
 160 Mon Jun 12 12:14:52 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 161
 162         * Makefile.in (distclean, realclean): Remove config.cache and
 163           config.log.
 164
 165 Wed May 17 17:56:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 166
 167         * Makefile.in (Makefile): Added config.status to dependency list.
 168           (config.status): New target.
 169           (SHELL): New definition.
 170
 171 Tue Apr 25 21:11:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 172
 173         * Makefile.in (install): Depend on "all".
 174
 175 Thu Apr 20 17:29:07 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 176
 177         * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
 178         to match configure script.
 179
 180 Wed Apr 19 11:19:37 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 181
 182         * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
 183           comment emitted by this script to gen-c-prog.awk.
 184
 185         * Makefile.in, configure.in: Converted to use autoconf.
 186         * configure: New file, generated with autoconf 2.3.
 187         * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
 188           mt-tahoe, mt-vax}: Removed.
 189
 190 Mon Mar 13 21:44:24 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 191
 192         * __bb_exit_func.c: New file, from David Mosberger-Tang.
 193
 194         Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 195
 196         * All *.c: More cleanup towards GNU format.
 197
 198         * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
 199         replaced sizeof (bfd_vma) by size (char*) because Ken tells me
 200         that bfd_vma is only guaranteed to be at least as big as a pointer.
 201
 202         (GMON_Record_tag): added explicit enumeration values to ensure
 203         compatibility across compilers.
 204
 205         * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
 206         sizeof(char*).
 207
 208 Tue Feb  7 17:24:12 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 209
 210         * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
 211         of constructs GNU indent couldn't handle.  Block comments not yet
 212         rewritten in GNU format.
 213
 214         * gprof.c (VERSION): Changed to 2.6, to get in sync for next
 215         binutils release.
 216
 217 Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 218
 219         * symtab.c (symtab_finalize): ensure globals symbols really
 220         are favored over static ones---even if their name looks less
 221         preferable; this is important for HP-UX; for example, there
 222         is a static label Ltext_something that aliases the global
 223         symbol _start
 224
 225         * hist.c (hist_print): auto-scaling is now in effect for FSF-style
 226         output only; also, auto-scaling is now performed based on
 227         per-call, rather than total execution time, which is what it was
 228         meant to be.
 229
 230         * gprof.h (File_Format): new type.
 231
 232         * gprof.c (VERSION): upped to 2.7---seems to be completely out of
 233         sync with Cygnus version numbers though...
 234
 235         (long_options): renamed --gmon-info to --file-info, --width added,
 236         renamed --old-file-format to --file-format
 237         (main): dito; also added support to read prof files, but as
 238         mon_out_read() is not implemented, it's #ifdef'd out for now
 239
 240         (usage): update to reflect new options.
 241
 242         * gmon_io.c: replaced "old_file_format" by more general
 243         "file_format" option
 244
 245         * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
 246
 247         * core.c (core_sym_class): added back check for __gnu_compiled and
 248         ___gnu_compiled for the benefit of systems without
 249         bfd_find_nearest_line() support
 250
 251         (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
 252         with section-relative addresses
 253
 254         (core_create_function_syms): get_src_info() calls are currently
 255         enabled for OSF/1 only.  It appears to work allright for SunOS
 256         4.1.x as well, but on SPARCs it gets painfully slow with the
 257         current implementation of aout_32_find_nearest_line();
 258         unfortunately, this means that static functions will not have their
 259         filename printed in the call-graph function index; line-level
 260         profiling should still work, but requires some patience
 261
 262         * cg_print.c (cg_print_index): sanitized printing of index when
 263         using FSF-style output; in particular, output width is now controlled
 264         via option --width and the function tries hard to keep columns
 265         aligned even in the presence of (occasional) long names
 266
 267         * NOTES: a first shot at updating the documentation.
 268
 269 Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 270
 271         * core.c (core_create_function_syms): fixed computation of min_vma
 272         and max_vma.
 273
 274         * *.c: removed rcsid.
 275
 276 Tue Jan 31 16:18:18 1995  Ken Raeburn  <raeburn@cujo.cygnus.com>
 277
 278         * Lots of changes from David Mosberger-Tang:
 279
 280         Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>
 281
 282         * gprof.c (main): put parentheses around & within &&.
 283
 284         * basic_blocks.c (bb_read_rec): print warning message (once) when
 285         ignoring basic-block execution counts.
 286
 287         * source.c (source_file_lookup_name): corrected second argument to
 288         strcmp().
 289
 290         * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
 291         Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
 292
 293         * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
 294         supported both for old and new (versioned) gmon.out files.  Old
 295         files are identified as version 0.
 296
 297         * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
 298         long (instead of 4) because that is what OSF/1 v3.0 uses.
 299
 300         * core.c: minor fixes and debugging info changes.
 301
 302         Sun Sep 11 18:47:47 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 303
 304         * core.c (core_init): if .text cannot be found, try $CODE$ (the
 305         name of the text-section under HP-UX).
 306
 307         * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
 308         points one past the last sampling bin, so hist_scale should be
 309         computed as "hist_scale /= hist_num_bins", not "hist_scale /=
 310         hist_num_bins - 1".
 311
 312         * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
 313         hist_num_bins.
 314
 315         * configure.in: added alpha-*-*) for per-target config.
 316
 317         * alpha.c, alpha.h: created.
 318
 319         * gprof.c (default_excluded_list): <locore>, <hicore> added.
 320
 321         * core.c (core_create_function_syms, core_create_line_syms):
 322         explicitly keep two sentinels "<locore>" and "<hicore>" that catch
 323         all addresses outside the text-space.  Thus, sym_lookup(&symtab,
 324         addr) continues to guarantee not to return 0 on any address.  It
 325         also avoids incorrectly crediting the first/last symbol in the
 326         text-space.
 327
 328         * core.c (core_create_line_syms): always create function symbols
 329         first, then merge in line symbols; this is so that if parts of the
 330         program were compiled without -g, function-level symbols are
 331         available still.
 332
 333         * utils.c (print_name_only): support for print_path added.
 334
 335         * symtab.c (cmp_addr): also use is_func flag in comparison.
 336         (symtab_finalize): return immediately when table empty; now
 337         more careful about getting rid of the right duplicate symbol.
 338
 339         * sparc.c (find_call): many fixes---this function was rather
 340         botched in binutils-2.4 already; it should work again.
 341
 342         * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
 343         not good to rely on get_src_info() to return distinct string
 344         pointers).
 345
 346         * search_list.c (search_list_append): added cast for xmalloc().
 347
 348         * hist.c: added explicit initialization to some of the global
 349         variables; fixed SItab (scales were off by a factor of 10).
 350
 351         * hist.h: include of bfd.h added.
 352
 353         * gprof.c, gprof.h (print_path): added.
 354
 355         * gprof.h (MAX): fixed.
 356
 357         * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
 358
 359         * gmon_io.c: added some casts to (long) so we can always print as %lx
 360
 361         * core.c (core_get_text_space): fixed to make it work.
 362
 363         * cg_print.c (cg_print_index): added support for print_path option.
 364
 365         * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
 366
 367         * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
 368         as some compilers complain (e.g., DEC's OSF/1 compiler)
 369
 370         * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
 371         symtab.c: calls to memset() had 2nd and 3rd args reversed.
 372
 373         Sat Sep 10 21:53:13 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 374
 375         * gprof.c: added "_mcount" to default_excluded_list.
 376         (main): if output_style==0 and there is either a histogram or a
 377         call-graph, always generate flat and call-graph, no matter what
 378         line_granularity is set to.
 379
 380         * source.c (source_file_lookup_name): if searching for sf->name
 381         fails, try again with filename obtained after stripping off any
 382         partial path from sf->name.
 383
 384         * gprof.h (SRCDEBUG): added.
 385
 386         * search_list.c (search_list_append): directories were added in wrong
 387         order.
 388
 389         * reimplemented selection mechanism from ground up; it is now possible
 390         to accurately control what gets included/excluded in each of the
 391         output styles;  a "symbol-specification" (spec) is the basic means
 392         to select a set of symbols; a spec has the syntax:
 393
 394           spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
 395           arc == spec/spec.
 396
 397         any of the terminal symbols can be empty, in which case they
 398         match anything (wildcards).  NAME is interpreted as a FILENAME
 399         if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
 400         with a digit, and as FUNCNAME otherwise.
 401
 402         For example, to get a call-graph display that ignores arcs
 403         from foo() to bar(), you'd say "--no-graph=foo/bar"; to
 404         show only arcs into bar() (no matter what the caller),
 405         you'd say "--graph=/bar"; and to get a call-graph without
 406         any arc info, you'd say "--graph=/";  similarly, to
 407         get a flat profile without mcount, you'd say "--no-flat=mcount"
 408         and to get a flat profile that shows includes all functions
 409         you'd say "--flat=""" (i.e., an empty spec)
 410
 411         * hist.c (hist_print): top_time wasn't initialized to 0.0.
 412
 413         Fri Sep  9 01:10:21 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 414
 415         * gmon_out.h: all headers now declared in terms of characters
 416           to avoid getting into trouble with different compilers introducing
 417           different amount of padding; the code already accessed the fields
 418           through bfd functions, so that didn't have to change.
 419
 420         * hist.c (hist_read_rec, hist_write_rec): added support for
 421           collection pc histograms measuring quantities other than time;
 422           the histogram header now includes a field that specifies the
 423           dimension of the quantity measured by the histogram bins
 424           (normally, this is "seconds", but other meaningful dimensions
 425            include such things as "I-cache misses", "instruction issue stalls"
 426            etc.); there is also a field to specify a one-character
 427           abbreviation for the dimension; in the case of time, this would
 428           be 's'; in most other cases it probably would be '1' (not a physical
 429           dimension).

 431         Thu Sep  8 16:05:08 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 432
 433         * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
 434           has become old_file_version; gmon_io.c now always supports old-style
 435           gmon.out files; it first tries to read gmon.out as a new version
 436           file, if that fails, it tries to read it in the old format;
 437           although not very likely, it is possible for gprof to mistake an
 438           old-style file as a new one (the first 4 bytes would have to
 439           be "gmon"---including the trailing '\0'); in that case, it is
 440           necessary to specify --old-file-version
 441
 442         * gprof.h: removed dependency on SYSV; the code now always uses
 443           strrchr(), memset(), and memcpy() and does not include either
 444           of string.h or strings.h; this should make gprof compile on
 445           any (Unix) system without configuration (per suggestion of
 446           raeburn@cygnus.com)
 447
 448         * gprof.c (usage): fixed location of --new-file-format option.
 449
 450         * cg_arcs.c (propagate_flags): fixed typo in declaration.
 451
 452         * flat_bl.m: removed formfeed at end of file; the form-feed
 453           is now printed cg_print.c only when necessary.
 454
 455         * major rewrite of gprof---too many changes to mention all of
 456           them.  new features:
 457
 458         + -l now requests profiling at the line level (as opposed
 459           to function level); in this mode, gprof creates a "symbol"
 460           (aka name-list entry) for each line of source code, instead
 461            of one per function)
 462
 463         + support for a new gmon.out file format; the new format
 464           consists of a header with a magic and a version number,
 465           followed by a sequence of profile data; profile data
 466           can any of: (a) PC histogram, (b) call-graph arcs, or
 467           (c) basic-block execution counts; the version number makes
 468           it possible to extend gmon.out in a backwards compatible
 469           fashion
 470
 471         + support for tcov style annotated output: if the gmon.out file
 472           contains basic-block execution counts, the user can request
 473           the generation of annotated source files, much like Sun's
 474           tcov used to do
 475
 476         + long options
 477
 478         + new scheme to suppress symbols that aren't function names
 479           (e.g., avoids mistaking a goto label as a function)
 480
 481         + reorganized source code to make it more managable; as a
 482           side effect, gprof now compiles cleanly with "gcc -Wall"
 483
 484         Thu Sep  1 15:46:49 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 485
 486         * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
 487         final cross-check to determine whether a static symbol should be
 488         considered as a function-name.
 489
 490         Fri Aug  5 19:32:36 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 491
 492         * gmon_io.c (gmon_out_read): recognize "-" as the filename for
 493         stdin; this is useful if you wanna keep gmon.out files compressed;
 494         this way you can "gzcat" the compressed file into gprof.
 495
 496         * gprof.c: flag_min_count now initialized with 1 instead of 0.
 497
 498         * basic_blocks.c (bb_annotate_source): added support for creating
 499         .tcov files when option flag_annotate_make_files is TRUE.
 500         (annotate_with_count): all counts less than the minimum count
 501         specified by -m are now annotated with hash-marks.
 502
 503         * gprof.c (main): -A is now followed by a string of option chars.
 504
 505         * basic_blocks.c (annotate_with_count): replaced b->count with
 506         cnt.
 507
 508         * source.c: flag_annotate_source replaced by source_lock_map.
 509
 510         * source.h: source_lock_map added.
 511
 512         * gprof.c (main): new command-line syntax: -S simply specifies
 513         which source-files user is interested in; -A requests annotated
 514         source files and -AA requests that all lines in a source file
 515         are annotated.
 516
 517         Thu Aug  4 23:27:03 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 518
 519         * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
 520
 521         * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
 522         so s_lowpc etc. get declared.
 523
 524         * arcs.h (doarcs): created.
 525
 526         * arcs.c: reordered static functions such that they get defined
 527         before use.
 528
 529         * gprof.c (main): added options:
 530            -A: request annotation of all source lines (with -S)
 531            -m: minimum execution count (with default basic-block display)
 532            -N: force new file format (only if BSD_COMPATIBLE is defined)
 533            -S: annotate source file
 534            -t: set table length (with -S)
 535
 536         * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
 537         source.o time_hist.o
 538
 539         Fri Jul  1 15:23:50 1994  David Mosberger-Tang  (davidm@piston.cs.arizona.edu)
 540
 541         * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
 542         on the fact being able to store a long in a double without loss of
 543         precision; this does not hold on machines with 64 bit longs and 64
 544         bit doubles.

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

 559         * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
 560         decls extern to keep native HP compiler quiet.
 561
 562 Tue Aug 30 11:12:13 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)

 566         underscore.

 723         * gprof.1: updated SYNOPSIS to match actual behavior.
 724
 725 Mon Oct  5 17:50:16 1992  Per Bothner  (bothner@cygnus.com)
 726
 727         * gen-c-prog.awk:  New awk script, lightly changed from
 728         previously deleted make-c-prog.awk.  Converts a text file
 729         to a c function that prints that text.
 730         * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
 731         Inputs to gen-c-prog.awk, containing text describing
 732         gprof output.
 733         * blurbs.c:  Removed.  Use *_bl.c instead.
 734         * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
 735         from *_bl.m files.  Also, improve *clean rules.
 736         * printgprof.c (printgprof):  Usw new function names from *_bl.c.

 740
 741         * gprof.h, gprof.c, printfgprof.c:  Add support for two
 742         output styles:  The default is similar to the old FSF gprof,
 743         while -T sets the variable bsd_style_output, which causes
 744         output matching Berkeley's gprof.  The biggest differences
 745         are that with the FSF style output, the flat profile comes
 746         before the call graph; numbers come before explanations;
 747         and there is less gratuitous white space.
 748         * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
 749         variable causes discarding of initial underscores when
 750         printing symbol names.  It is set unless there is a "main"
 751         symbol (without an underscore).
 752         * printfgprof.c:  New function printnameonly(), called
 753         by printname().  It handles stripping of initial '_',
 754         as well as C++ name-demangling.
 755         * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
 756         It is just as convenient to edit blurbs.c directly.
 757         * Makefile.in:  Removed rule for making blurbs.c.
 758         * blurbs.c:  This is now a true source file (as opposed
 759         to being generated from gprof.callg and gprof.flat).
 760         Change style to use one long string literal, instead of
 761         one literal per output line.  Add FSF-style blurb for call graph.

 763 Wed Aug 19 14:36:39 1992  Ian Lance Taylor  (ian@cygnus.com)
 764
 765         * Makefile.in: always create installation directories.
 766
 767 Wed Aug 12 15:14:14 1992  Mark Eichin  (eichin@cygnus.com)
 768
 769         * Makefile.in: change ${MACHINE} to $(MACHINE).

 772
 773         * Makefile.in:  removed installation of the now useless
 774         call.{flag,callg} files.
 775
 776         * gprof.1: now uses the standard man macros instead of the new BSD
 777         mandoc macros.
 778
 779 Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)
 780
 781         * configure.in:  Remove host section, expand target section.
 782         * config/mt-{tahoe,vax}:  Add, to match existing support files.
 783         * config/tmake-*:  Remove leftover crud.
 784
 785         * blurbs.c:  New file, created from gprof.flat and gprof.callg by
 786         * make-c-prog.awk:  which processes text files into C programs.
 787         * printgprof.c (flatprofheader, gprofheader):  Call new functions
 788         to print blurbs.
 789         (printblurb):  Remove.
 790         * Makefile.in:  Infrastructure to build blurbs.
 791         * pathnames.h:  has been removed.  Gprof now has no filename
 792         dependencies in it.
 793         * gprof.c:  Lint.

 796
 797         * Makefile.in: define man1dir and install the man page

 801         * Makefile.in: added dummy info and install-info targets
 802
 803 Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)
 804
 805         * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
 806         help in debugging the problem (with -DDEBUG)
 807         * gprof.c: symbol values are now real values, don't add the vma
 808         anymore. (done for solaris; should verify this on other platforms)
 809         * ChangeLog: created.
