2
3 * etc/bench.pm: Shorten bench names.
4
5 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6
7 * src/output.h, src/output.c (error_verbose): Move to...
8 * src/getargs.h, src/getargs.c: here.
9 Sort the flags.
10 Adjust dependencies.
11
12 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
13
14 * data/c.m4 (b4_copyright): Put the special exception for Bison
15 skeletons here, so we don't have to put it in each skeleton. All
16 uses changed. Suggested by Akim Demaille. Also, wrap the
17 copyright notice, in case it is longer than 80 columns. Replace
18 comma by newline after title.
19
20 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
21
22 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
23 incompatibility, not a bug. Mention that it wasn't fixed as of
24 flex 2.5.33.
25
26 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
27
28 * examples/extexi: Enforce the precedence of concatenation over
29 >>.
30 Reported by Tommy Nordgren.
31
32 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
33
34 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
35 with the member "token".
36 Reported by Martin Nylin.
37
38 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
39
40 * data/glr.c: Switch to Bison 2.2 special-exception language in
41 the copyright notice. Use more-regular format for titles and
42 copyright notices.
43 * data/glr.cc: Likewise.
44 * data/location.cc: Likewise.
45 * data/yacc.cc: Likewise.
46 * doc/bison.texinfo (Conditions): Document this.

48
49 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
50
51 * data/glr.cc: Remove dead code.
52
53 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
54
55 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
56 that variable and the line breaks the bootstrap. Problem reported
57 by Juan M. Guerrero.
58
59 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
60
61 * doc/bison.texinfo (Multiple start-symbols): New.
62
63 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
64
65 * etc/README, etc/bench.pl: New.
66
67 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
68
69 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
70 rule.
71 Reported by Mickael Labau.
72 * tests/input.at (Torturing the Scanner): Test it.
73
74 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
75
76 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
77 Problem reported by Bob Rossi.
78
79 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
80
81 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
82 and didn't really work.
83 For the index, use @ifnotinfo, not @iftex.
84 Minor cleanups of spacing and terminology.
85
86 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
87
88 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
89 of AT_NAME_PREFIX when %name-prefix is not used.
90
91 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
92
93 Apply --prefix to C++ skeletons too: they change the namespace.
94 The test suite already exercize these cases.
95 * data/c++.m4 (b4_namespace): New.
96 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
97 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
98 * data/yacc.c, data/glr.c: Remove a useless `[]'.
99 * doc/bison.texinfo: Document it.
100 (Option Cross Key): Use @multitable in all formats. It looks
101 nicer, even in TeX outputs.
102 (Rules): Use the same code whatever the output type is.
103 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
104 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
105 * tests/calc.at: Use it, instead of hard coding `yy'.
106
107 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
108
109 * TODO: Remove dead items.
110
111 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
112
113 * doc/FAQ: Remove, merged into...
114 * doc/bison.texinfo (FAQ): this.
115 * doc/Makefile.am (EXTRA_DIST): Adjust.
116
117 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
118
119 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
120 even if empty.
121 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
122 * doc/bison.texinfo (Calc++ Scanner): Use it.
123
124 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
125
126 Fix two nits reported by twlevo, plus one more that I discovered.
127
128 * src/assoc.h (assoc_to_string): Give a name to the arg, as
129 this is the usual Bison style.
130 * src/location.h (location_print): Likewise.
131
132 * src/reader.h (token_name): Likewise.
133
134 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
135
136 Fix some nits reported by twlevo.
137 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
138 and "POSIX". Use more-modern syntax for URLs. Mention C++
139 and ask for Java. Don't hardwire OS version numbers. Add
140 copyright notice.
141 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
142 * src/conflicts.c (solved_conflicts_obstack): Now static.
143
144 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
145
146 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
147 page. Say "you can use it" not "you may use it" as on the web page;
148 we're describing capabilities not granting permission.
149
150 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
151
152 * data/glr.c (yyresolveLocations): Rename local variables to avoid
153 shadowing warnings. Use usual patter for iterating through RHS.
154 * tests/glr-regression.at
155 (Uninitialized location when reporting ambiguity):
156 Modify yylex so that it uses its argument, rather than trying
157 to rely on ARGSUSED (which doesn't work for gcc with warnings).
158 const char -> char const.
159
160 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
161 Don't use tabs inside commands; it messes up 'ps'.
162 Problem reported by twlevo.
163
164 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
165
166 * tests/glr-regression.at (Uninitialized location when reporting
167 ambiguity): New test case.
168 * data/glr.c (yyresolveLocations): New function, which uses
169 YYLLOC_DEFAULT.
170 (yyresolveValue): Invoke yyresolveLocations before reporting an
171 ambiguity.
172 * doc/bison.texinfo (Default Action for Locations): Note
173 YYLLOC_DEFAULT's usage for ambiguity locations.
174 (GLR Semantic Actions): Cross-reference those notes.
175
176 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
177
178 * tests/glr-regression.at (Leaked semantic values when reporting
179 ambiguity): Remove unnecessary union and type declarations.
180 (Leaked lookahead after nondeterministic parse syntax error): New test
181 case.
182 * data/glr.c (yyparse): Check for zero stacks remaining before
183 attempting to shift the lookahead so that you don't lose it.
184
185 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
186
187 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
188 * tests/glr-regression.at (Leaked semantic values when reporting
189 ambiguity): New test case.
190 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
191 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
192 now unnecessary yystackp parameter.
193 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
194 destructors can be called.
195
196 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
197 in existing testcases.
198
199 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
200
201 Don't leak semantic values for parent RHS when a user action cuts the
202 parser, and clean up related code a bit.
203 * tests/glr-regression.at (Leaked merged semantic value if user action
204 cuts parse): Rename to...
205 (Leaked semantic values if user action cuts parse): ... this. Add check
206 for leaked parent RHS values.
207 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
208 between an unresolved state (non-empty chain of semantic options) and
209 an incomplete one (signaled by an empty chain).
210 (yyresolveStates): Document the interface. Move all manipulation of a
211 successfully or unsuccessfully resolved yyGLRState to...
212 (yyresolveValue): ... here so that yyresolveValue always leaves a
213 yyGLRState with consistent data and thus is easier to understand.
214 Remove the yyvalp and yylocp parameters since they are always just
215 taken from the yys parameter. When reporting a discarded merged value
216 in debugging output, note that it is incompletely merged. Document the
217 interface.
218 (yyresolveAction): If resolving any of the RHS states fails, destroy
219 them all rather than leaking them. Thus, as long as user actions are
220 written to clean up the RHS correctly, yyresolveAction always cleans up
221 the RHS of a semantic option. Document the interface.
222
223 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
224
225 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
226 led to a segmentation fault in GNU Pascal. Problem reported
227 by Waldek Hebisch.
228
229 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
230
231 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
232 mid-rule action inside a nonterminal symbol in order to declare a
233 destructor for its semantic value.
234
235 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
236
237 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
238 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
239 __cplusplus && ! defined _STDLIB_H && !
240 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
241 defined free))]: Include <stdlib.h> rather than rolling our own
242 declarations of malloc and free, to avoid problems with
243 incompatible declarations (using 'throw') C++'s stdlib.h. This
244 should fix Debian bug 340012
245 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
246 reported by Guillaume Melquiond.
247
248 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
249
250 * NEWS: Clarify symbols versus types in unused-value warnings.
251
252 * configure.ac (AC_INIT): Bump version number.
253
254 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
255
256 * NEWS: Version 2.1a.
257 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
258 since C99 requires this.
259
260 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
261
262 * m4/c-working.m4: New file.
263 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
264
265 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
266
267 * Makefile.maint: Merge from coreutils.
268
269 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
270
271 More portability fixes for problems summarized by Nelson H. F. Beebe.
272
273 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
274 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
275 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
276 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
277 messes up because C++ code is compiled in 32-bit mode but linked
278 in 64-bit mode.
279
280 2006-02-08 Paul Eggert <eggert@cs.ucla.edu>
281
282 More portability fixes for problems summarized by Nelson H. F. Beebe.
283
284 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
285 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
286
287 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
288 nodist_PROGRAMS, since we don't need to actually compile the
289 example if we're just doing a plain 'make'. This avoids bothering
290 the installer unnecessarily about problems due to weird C++
291 compilers.
292
293 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
294
295 More portability fixes for problems summarized by Nelson H. F. Beebe.
296
297 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
298 than #include "...", and compile with -I'.'. The old method was
299 not portable, according to Posix and the C standard, and it does
300 not work with Sun C 5.7, where previous #line directives affect
301 the working directory used in later #include "..." directives.
302
303 2006-02-06 Juan Manuel Guerrero <juan.guerrero@gmx.de>
304
305 Various DJGGP specific issues in /djgpp
306
307 2006-02-02 Paul Eggert <eggert@cs.ucla.edu>
308
309 More portability fixes for problems summarized by Nelson H. F. Beebe.
310
311 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
312 '#include <map>' works and that you can apply ++ to iterators.
313
314 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
315
316 Work around portability problems summarized by Nelson H. F. Beebe in
317 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
318
319 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
320 that '#include <string>' works.
321
322 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
323 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
324 "warning: sorry: semantics of inline function static data `const
325 unsigned char translate_table[262]' are wrong (you'll wind up with
326 multiple copies)".
327
328 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
329 or, xor to not_, and_, or_, and xor_, respectively. This works
330 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
331 random system header somewhere that includes the equivalent of
332 <iso646.h>.
333
334 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
335 -E" works; it apparently doesn't work with PathScale EKO Compiler
336 Suite Version 2.0.
337
338 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
339
340 During deterministic GLR operation, user actions should be able to
341 influence the parse by changing yychar. To make this easier to fix and
342 to make glr.c easier to evolve in general, don't maintain yytoken in
343 parallel with yychar; just compute yytoken when needed.
344 * tests/glr-regression.at (Incorrect lookahead during deterministic
345 GLR): Check that setting yychar in a user action has the intended
346 effect.
347 * data/glr.c (yyGLRStack): Remove yytokenp member.
348 (yyclearin): Don't set *yytokenp.
349 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
350 yychar rather than *yytokenp to determine the current lookahead.
351 Compute yytoken locally when needed.
352 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
353 point to.
354
355 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
356 after `--report' documentation.
357
358 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
359
360 * src/parse-gram.y (grammar_declaration): Location of printer
361 symbol is @1, not list->location. Bug reported by twlevo.
362 * tests/input.at (Incompatible Aliases): Adjust to above change.
363
364 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
365
366 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
367 all the test at once. This makes the output easier to read in the
368 normal case.
369
370 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
371 got from <http://bro-ids.org/download.html>. The bug is that
372 when two actions appeared in succession, the second one was
373 scanned before the first one was added to the grammar rule
374 as a midrule action. Bison then output the incorrect warning
375 "parse.y:905.17-906.36: warning: unused value: $3".
376 * src/parse-gram.y (BRACED_CODE, action): These are no longer
377 associated with a value.
378 (rhs): Don't invoke grammar_current_rule_action_append.
379 (action): Invoke it here instead.
380 * src/reader.c (grammar_midrule_action): Now extern.
381 (grammar_current_rule_action_append): Don't invoke
382 grammar_midrule_action; that is now the scanner's job.
383 * src/reader.h (last_string, last_braced_code_loc):
384 (grammar_midrule_action): New decls.
385 * src/scan-gram.l (last_string): Now extern, sigh.
386 (last_braced_code_loc): New extern variable.
387 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
388 rule already has an action.
389 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
390 * tests/input.at (AT_CHECK_UNUSED_VALUES):
391 Add some tests to check that the above changes fixed the bug.
392
393 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
394
395 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
396 All used changed. Check whether the symbol has a destructor,
397 not whether it is typed.
398 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
399 that the values are still reported as unused. All line numbers
400 adjusted.
401
402 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
403
404 Work around a bug in bro 0.8, which underparenthesizes its
405 definition of YYLLOC_DEFAULT.
406 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
407 their arguments.
408 * data/lalr1.cc: Likewise.
409 * data/yacc.cc: Likewise.
410
411 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
412
413 Work around a bug in Pike 7.0, and give the Pike folks a
414 better way to override the usual int widths.
415 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
416 user can override the types.
417 (short): #undef, to work around a bug in Pike 7.0.
418 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
419 (union yyalloc.yyss): Use yytype_int16 rather than short.
420 All uses changed.
421 (yysigned_char): Remove.
422 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
423 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
424 * tests/regression.at (Web2c Actions): Adjust to above changes.
425
426 * src/reader.c (check_and_convert_grammar): New function.
427 (reader): Close the input file even if something went wrong during
428 parsing. Minor file descriptor leak reported by twlevo.
429
430 * src/assoc.c (assoc_to_string): Use a default: abort (); case
431 to pacify gcc -Wswitch-default.
432 * src/scan-gram.l (adjust_location): Use a default: break; case
433 to pacify gcc -Wswitch-default.
434 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
435 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
436 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
437 Move these decls to scan-skel.l, since they don't need to be
438 visible elsewhere.
439 * src/scan-skel.l: Accept the above decls.
440 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
441 is used.
442
443 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
444
445 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
446 since we don't want to insist on a version number at the start
447 of the changelog every time.
448 * Makefile.maint: Sync from coreutils a bit better.
449 (sc_trailing_blank): Renamed from sc_trailing_space.
450 All uses changed.
451 (sc_no_if_have_config_h, sc_require_config_h):
452 (sc_prohibit_assert_without_use): New rules.
453 (sc_obsolete_symbols): Don't catch Makefile.maint itself.
454 (sc_dd_max_sym_length): Fix leading spaces in rule.
455 (sc_system_h_headers): Prefix with @.
456 (sc_useless_cpp_parens, m4-check): Output line numbers.

544 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
545 that '#include <cstdlib>' works.

552
553 Minor fixups to get 'make maintainer-check' to work.

598 (changelog-check): Don't require version number near head.
599 (copyright-check): Use current year instead of hardwiring 2005.

602
603 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
604 with "file system".

625 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
626
627 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
628
629 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
630
631 * doc/bison.texinfo: Fix some typos.
632 (GLR Semantic Actions): New subsection discussing special
633 considerations because GLR semantic actions might be deferred.
634 (Actions): Mention look-ahead usage of yylval.
635 (Actions and Locations): Mention look-ahead usage of yylloc.
636 (Special Features for Use in Actions): Add YYEOF entry and mention it
637 in the yychar entry.
638 In the yychar entry, remove mention of the local yychar case (pure
639 parser) since this is irrelevant information when writing semantic
640 actions and since it's already discussed in `Bison Symbols' where
641 yychar is otherwise described as an external variable.
642 In the yychar entry, don't call it the `current' look-ahead since it
643 isn't when semantic actions are deferred.
644 In the yychar and yyclearin entries, add note about deferred semantic
645 actions.
646 Add yylloc and yylval entries discussing look-ahead usage.
647 (Look-Ahead Tokens): When discussing yychar, don't call it the
648 `current' look-ahead, and do mention yylval and yylloc.
649 (Error Recovery): Cross-reference `Action Features' when mentioning
650 yyclearin.
651 (Bison Symbols): In the yychar entry, don't call it the `current'
652 look-ahead.
653 In the yylloc and yylval entries, mention look-ahead usage.
654
655 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
656
657 * tests/glr-regression.at: Update copyright year to 2006.
658
659 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
660
661 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
662 use during nondeterministic operation to track which stacks have
663 actually needed the current lookahead.
664 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
665 Allocate, deallocate, resize, and otherwise shuffle space for
666 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
667 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
668 appropriately during nondeterministic operation.
669 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
670 members to store the current lookahead to be used by the deferred
671 user action.
672 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
673 from which the RHS is taken. Set the lookahead members of the new
674 yySemanticOption according to the lookahead status for stack yyk.
675 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
676 yyaddDeferredAction.
677 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
678 members of yySemanticOption before invoking yyuserAction, and then set
679 them back to their current values afterward.
680 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
681 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
682 * tests/glr-regression.at: Remove `.' from the ends of recent test case
683 titles for consistency.
684 (Leaked merged semantic value if user action cuts parse): In order to
685 suppress lint warnings, use arguments in merge function, and assign
686 char value < 128 in main.
687 (Incorrect lookahead during deterministic GLR): New test case.
688 (Incorrect lookahead during nondeterministic GLR): New test case.
689
690 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
691
692 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
693 !yyvaluep as signal that no semantic value is available to print.
694 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
695 to print a semantic value.

698
699 * tests/glr-regression.at: For consistency with my newer test cases,
700 don't thank myself.
701
702 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
703
704 * data/glr.c (yyresolveValue): When merging semantic options, if at
705 least one user action succeeds but a later one cuts the parse, then
706 destroy the semantic value before returning rather than leaking it.
707 (yyresolveStates): If a user action cuts the parse and thus
708 yyresolveValue fails, ignore the (unset) semantic value rather than
709 corrupting the yyGLRState, and empty the semantic options list since
710 the user actions should have called all necessary destructors.
711 Simplify code with YYCHK.
712 * tests/glr-regression.at (Corrupted semantic options if user action
713 cuts parse): New test case.
714 (Undesirable destructors if user action cuts parse): New test case.
715 Before applying any of this patch, this test case never actually failed
716 for me... but only because the corrupted semantic options usually
717 masked this bug.
718 (Leaked merged semantic value if user action cuts parse): New test
719 case.
720
721 2006-01-05 Akim Demaille <akim@epita.fr>
722
723 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/.

748
749 2006-01-04 Akim Demaille <akim@epita.fr>
750
751 * src/reader.c (grammar_midrule_action): If $$ is set in a
752 mid-rule, move the `used' bit to its lhs.
753 * tests/input.at (Unused values): New.
754 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
755
756 2006-01-03 Paul Eggert <eggert@cs.ucla.edu>
757

759 --yacc does.
760 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
761 about declarations in the grammar when in Yacc mode, as POSIX does
762 not require a diagnostic when the grammar uses extensions.
763
764 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
765
766 Warn about dubious constructions like "%token T T".
767 Reported by twlevo.

781
782 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:

790 (b4_parse_param): Improve its definition, and bound it more
791 clearly in the skeleton.
792 (b4_epilogue): Append, instead of prepending, in order to keep
793 #line consistency.
794 Simplify the generation of auxiliary functions: locations and
795 purity are mandated.
796 (b4_global_tokens_and_yystype): Honor it.
797 * data/location.cc (c++.m4): Don't include it.
798 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
799 and AT_SKEL_CC_IF.

807
808 2006-01-02 Akim Demaille <akim@epita.fr>
809
810 * src/output.c (output_skeleton): Don't hard wire the inclusion of

824
825 Let glr.cc catch up with symbol_value_print.

864 Rename as...
865 (grammar_rule_begin, grammar_rule_end): these, for consistency.
866 (grammar_midrule_action, grammar_symbol_append): Now static.
867 * tests/torture.at (input): Don't rely on the default action
868 being always performed.
869 * tests/calc.at: "Set" $$ even when the action is "cut" with
870 YYERROR or other.
871 * tests/actions.at (Exotic Dollars): Instead of using unused
872 values, check that the warning is issued.
873
874 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
875
876 * NEWS: Improve wording for unused-value warnings.
877
878 2005-12-22 Akim Demaille <akim@epita.fr>

896 * src/symtab.c (symbol_print): Accept 0.
897 * tests/existing.at: Remove the type information.
898 Empty the actions.
899 Remove useless actions (beware of mid-rule actions: perl -000
900 -pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
901 * tests/actions.at (Exotic Dollars): Use unused values.
902 * tests/calc.at: Likewise.
903 * tests/glr-regression.at (No users destructors if stack 0 deleted):
904 Likewise.

910
911 Undo 2005-12-01 tentative license wording change. The wording is
912 still being reviewed by the lawyers, and we don't want to wait for
913 them before publishing a test release. For now, revert to the
914 previous wording.
915 * NEWS: Undo 2005-12-01 change.
916 * data/glr.c: Revert to previous license wording.
917 * data/glr.cc: Likewise.
918 * data/lalr1.cc: Likewise.
919 * data/location.cc: Likewise.
920 * data/yacc.c: Likewise.
921
922 * NEWS: Reword %destructor vs YYABORT etc.
923 * data/glr.c: Use American spacing, for consistency.
924 * data/glr.cc: Likewise.
925 * data/lalr1.cc: Likewise.
926 * data/yacc.c: Likewise.
927 * data/yacc.c: Reformat comments slightly.
928 * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
929 for consistency. Fix some spelling errors and reword recently-included
930 text slightly.
931 * tests/cxx-type.at: Cast results of malloc, for C++.
932
933 2005-12-21 Joel E. Denny <address@hidden>
934
935 * tests/cxx-type.at: Construct a tree, count the parents of shared
936 nodes, and free each node once and only once. Previously, the memory
937 for semantic values was leaked instead.
938
939 2005-12-21 Joel E. Denny <address@hidden>
940
941 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
942 (yylval, yylloc): If pure, #define to yystackp->yyval and
943 yystackp->yyloc similar to yychar and yynerrs.
944 (yyparse): If pure, remove local yylval and yylloc. Add local
945 yystackp to accommodate pure definitions of yylval and yylloc.
946 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
947 yylvalp and yyllocp to &yylval and &yylloc.
948 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]

950 weren't necessary.
951 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
952 yylvalp and yyllocp parameters since, if pure, these are now always
953 accessible through yystackp. If not pure, they are still accessible
954 globally.
955 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
956 `if (YYID (N))' to pacify lint.
957
958 2005-12-21 Akim Demaille <akim@epita.fr>
959
960 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
961 destroy the RHS symbols of a rule.
962 * data/yacc.c (yylen): Initialize to 0.
963 Keep its value to the number of items to possibly shift.
964 In particular, a regular successful parse that ends on YYFINAL by
965 a (internal) YYACCEPT must not have yylen != 0.
966 (yyerrorlab, yyreturn): Pop the RHS.
967 Reorder a bit to emphasize the `shifting' bits of code.
968 (YYPOPSTACK): Now accept a number of items to pop.

977 * djgpp/Makefile.maint: Fix PACKAGE variable computation.
978 * djgpp/config.bat: Replace every occurence of the file name
979 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
980 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
981 * djgpp/config.sed: Replace every occurence of the file name
982 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
983 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
984 * djgpp/djunpack.bat: DJGPP specific file.
985 * djgpp/fnchange.lst: DJGPP specific file.
986 * djgpp/README.in: Add new information about how to unpack the bison
987 source on MSDOS and other systems which have 8.3 file name restrictions
988 using djunpack.bat and fnchange.lst.
989

996 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
997
998 * data/glr.c: Reorder typedef declarations for structs to match order
999 of struct declarations.
1000 Rename yystack everywhere to yystackp except in yyparse where it's not
1001 a pointer.
1002 (yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
1003 consistency.
1004 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
1005 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
1006 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
1007 lint.
1008
1009 2005-12-09 Paul Eggert <eggert@cs.ucla.edu>
1010
1011 * tests/sets.at (Accept): Fix typos in regular expression used to
1012 sed out the final state number.
1013
1014 Work around portability problem on Solaris 10: flex-generated
1015 files include <stdio.h> before <config.h>, which messes up
1016 because the latter defines __EXTENSIONS__. Address the problem
1017 by creating two new little files that include <config.h> first,
1018 then include the flex-generated files. Rewrite everyone else
1019 to include <config.h> first, as well.
1020 * lib/timevar.c: Always include "config.h".
1021 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

1056 (current_assoc): Remove unused variable.
1057
1058 Cleanups so that Bison-generated parsers have less lint.
1059 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
1060 Prepend /*ARGSUSED*/, for lint's sake.
1061 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
1062 definition if 'lint' is defined.
1063 (YYID): New macro (or function, if lint).
1064 All uses of /*CONSTCOND*/0 replaced by YYID(0).
1065 * data/yacc.c: Likewise.
1066 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
1067 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
1068 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
1069 is C++ only.
1070 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
1071 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
1072 Use YYID(0) rather than 0, for lint.
1073 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
1074 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

1088 New test case.
1089 (Duplicated user destructor for lookahead): This test now is expected
1090 to succeed.
1091
1092 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
1093
1094 * NEWS: Document the following change.
1095 * data/yacc.c: Say "parser skeleton" rather than "file", since
1096 it's no longer just a file.
1097 * data/glr.c: Grant a special exception for C GLR parsers, that
1098 reads like the already-existing exception for C LALR(1) parsers.
1099 * data/glr.cc: Likewise.
1100 * data/lalr1.cc: Likewise.
1101 * data/location.cc: Likewise.
1102 * data/yacc.c: Reword the "written by" statement to clarify that
1103 it was the parser skeleton, not the entire output file.
1104 * data/glr.c: Written by Paul Hilfinger.
1105 * data/glr.cc: Written by Akim Demaille.
1106 * data/lalr1.cc: Likewise.

1109
1110 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
1111 Fix typos in previous change that broke 'make check'.
1112 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
1113 supported in C.
1114 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
1115 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
1116 We can revert this once things settle down.
1117
1118 * src/conflicts.c (conflicts_print): Don't print file name twice
1119 when %expect fails because there were no conflicts.
1120 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
1121 change.
1122 * tests/conflicts.at (%expect not enough, %expect too much):
1123 (%expect with reduce conflicts): Adjust to new behavior.

1147 2005-11-14 Akim Demaille <akim@epita.fr>
1148
1149 * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
1150 from 1 to N, while values and location start at 0.
1151 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
1152

1255
1256 * bootstrap (cleanup_gnulib): New function. Use it to clean up
1257 gnulib when interrupted. This fixes some race conditions and
1258 works around some portability problems (one noted by Paul
1259 Hilfinger).

1303 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
1304
1305 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
1306 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
1307 Problem reported by John P. Hartmann.
1308 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
1309 already defined it.

1337
1338 * data/c.m4 (yydestruct, yysymprint):
1339 Use YYUSE instead of casting to void.
1340 * data/glr.c (YYUSE): New macro.
1341 (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
1342 Use it instead of rolling our own.
1343 (YYLLOC_DEFAULT, YYCHK, YYDPRINTF, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
1344 (YYCHK1):
1345 Use /*CONSTCOND*/ to suppress lint warnings.
1346 * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
1347 (YY_STACK_PRINT): Use 'false' not '0'.

1358
1359 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
1360
1361 Undo the parts of the unlocked-I/O change that substituted
1362 putc or puts for printf. This might hurt performance a bit,
1363 but some people prefer the printf style.
1364 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
1365 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.
1366 All uses replaced by YYFPRINTF and YYDPRINTF.
1367 * data/yacc.c: Likewise.
1368 * lib/bitset.c (bitset_print): Likewise.
1369 * lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer printf to

1375 * src/output.c (escaped_output): Likewise.
1376 (user_actions_output): Break apart two printfs.

1380 * src/system.h: Include unlocked-io.h rathe than stdio.h.
1381
1382 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
1383 Use assignments rather than casts-to-void to suppress
1384 unused-variable warnings. This pacifies 'lint'.
1385 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
1386 unused-variable warnings.
1387
1388 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
1389
1390 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
1391
1392 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
1393
1394 Use unlocked I/O for a minor performance improvement on hosts like
1395 GNU/Linux and Solaris that support unlocked I/O. The basic idea
1396 is to use the gnlib unlocked-io module, and to prefer putc and
1397 puts to printf when either will work (since the latter doesn't
1398 come in an unlocked flavor).
1399 * bootstrap (gnulib_modules): Add unlocked-io.
1400 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
1401 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

1403 and similarly for puts and putc and printf.
1404 * data/yacc.c: Likewise.
1405 * lib/bitset.c (bitset_print): Likewise.
1406 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.

1410 * src/closure.c (print_firsts, print_fderives): Likewise.
1411 * src/gram.c (grammar_dump): Likewise.
1412 * src/lalr.c (look_ahead_tokens_print): Likewise.
1413 * src/output.c (escaped_output): Likewise.
1414 (user_actions_output): Coalesce two printfs.

1417 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
1418 * src/system.h: Include unlocked-io.h rather than stdio.h.
1419
1420 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
1421 this confuses xgettext.

1464
1465 * lib/subpipe.c: New function end_of_output_subpipe() added
1466 to allow support for non-posix systems. This is a no-op function
1467 for posix systems.
1468
1469 * lib/subpipe.h: New function end_of_output_subpipe() added
1470 to allow support for non-posix systems. This is a no-op function
1471 for posix systems.
1472
1473 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
1474 handle the lack of pipe/fork functionality on non-posix systems.

1495 * data/lalr1.cc: here.
1496 (location.hh): Include it after the user prologue, in case the
1497 filename type is defined by the user.
1498 Forward declation location and position before the pre-prologue.
1499 (yyresult_): Rename as...
1500 (yyresult): this, it's a local variable, not an attribute.
1501 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
1502
1503 2005-10-01 Akim Demaille <akim@epita.fr>

1538 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
1539 parser members, replaced by...
1540 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
1541 local variables.
1542 (yysyntax_error_): Takes the state number as argument.
1543 (yyreduce_print_): Use the argument yyrule, not the former
1544 attribute yyn_.
1545
1546 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
1547
1548 * bootstrap (gnulib_modules): Add verify.

1559 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1560 Trivial changes from Joel E. Denny.
1561
1562 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
1563 it itself.
1564 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
1565 don't use alloca any more.
1566
1567 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
1568 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
1569 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
1570 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
1571 to match yacc.c, to test more hosts.
1572
1573 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
1574
1575 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
1576 doesn't affect behavior.
1577 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
1578 Solaris, AIX, MSC.
1579 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
1580 This works a bit better with glibc, if user code has already included
1581 stdlib.h.
1582 * doc/bison.texinfo (Bison Parser): Document that users can't
1583 arbitrarily use malloc and free for other purposes. Document
1584 that <alloca.h> and <malloc.h> might be included.
1585 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
1586 user must declare alloca.

1597 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
1598 (YYSTACK_ALLOC_MAXIMUM): Use it.
1599 (yysyntax_error): New function.
1600 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
1601 multiple syntax errors are reported, and alloca is being used.
1602 Instead, reallocate buffers twice as big each time, so that
1603 we waste at most half the allocated memory. Start with a small
1604 (128-byte) buffer that will suffice in most cases anyway.
1605 Use yysyntax_error to do most of the work.
1606
1607 * doc/bison.texinfo (Error Reporting, Table of Symbols):
1608 yynerrs is the number of errors reported, not the number of
1609 errors encountered.
1610
1611 * tests/glr-regression.at (Duplicated user destructor for lookahead):
1612 Mark it as expected to fail.
1613 Cast result of malloc; problem reported by twlevo@xs4all.nl.
1614 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
1615 Don't start user-code symbols with "yy", to avoid name space problems.
1616
1617 2005-09-19 Akim Demaille <akim@epita.fr>
1618
1619 Remove the traits, failed experiment.
1620 It never proved useful, and anyway because of the current
1621 definition, it was not possible to have several specialization of
1622 this traits, making it useless.
1623 * data/lalr1.cc (yy:traits): Remove.
1624 Inline its definitions in the parser class.
1625
1626 2005-09-19 Akim Demaille <akim@epita.fr>

1647 diagnostic.
1648 * src/output.c (prepare): Likewise.
1649 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
1650 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
1651 is not defined. This is an awful hack, but it's enough for now.
1652 All callers changed.
1653 * tests/glr-regression-at (make_value): Args are const pointers now,
1654 to avoid GCC warning.
1655 (Duplicated user destructor for lookahead): New test. Currently
1656 skipped. It fails on my host but I'm not sure it'll always fail.
1657
1658 2005-09-16 Akim Demaille <akim@epita.fr>
1659
1660 * src/symtab.h (struct symbol): Declare the printer and destructor

1679 (yyreport_syntax_error_): Remove, replaced by...
1680 (yysyntax_error_): this which returns a string and leaves to the
1681 caller the call to the users' error function.
1682 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
1683 Move from members of the parser object...
1684 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
1685 to local variables of the parse function.
1686
1687 2005-09-16 Akim Demaille <akim@epita.fr>
1688

1693
1694 * data/glr.c (yyresolveValue): Add default case to pacify

1706 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
1707
1708 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
1709 do anything if $@ exists. This reverts part of the 2005-07-07
1710 patch.
1711
1712 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
1713
1714 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
1715 contains obsolete information and isn't worth distributing as a
1716 separate file anyway.
1717 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
1718 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

1724
1725 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
1726 Suggested by twlevo@xs4all.nl.
1727
1728 * data/glr.c (YYCHK1): Do not assume YYE is in range.
1729 This avoids a diagnostic from gcc -Wswitch-enum.
1730 Problem reported by twlevo@xs4all.nl.
1731
1732 * doc/bison.texinfo: Don't use "filename", as per GNU coding
1733 standards. Use "file name" or "file" or "name", depending on
1734 the context.
1735 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
1736 not to hack/foo.tab.c.
1737 (Calc++ Top Level): 2nd arg of main is not const.
1738 * data/glr.c: b4_filename -> b4_file_name.
1739 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

1751
1752 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
1753 to accommodate latest gnulib.
1754
1755 * tests/glr-regression.at (Duplicate representation of merged trees):
1756 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
1757
1758 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
1759 needed.
1760
1761 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1762
1763 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
1764 All uses changed. Invoke user destructor after an error during a
1765 split parse (trivial change from Joel E. Denny).
1766
1767 * tests/glr-regression.at
1768 (User destructor after an error during a split parse): New test case.
1769 Problem reported by Joel E. Denny in:
1770 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
1771
1772 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
1773
1774 * README-cvs: Give URLs for recommended tools.
1775 Mention Gzip version problem, and bootstrapping issues.
1776 Remove troubleshooting section, as it's somewhat obsolete.
1777
1778 * bootstrap (no_cache): New var, to accommodate different wget
1779 variants. Use it instead of '-C off'. Problem reported by
1780 twlevo@xs4all.nl.
1781
1782 * data/glr.c (yydestroyStackItem): New function.
1783 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
1784 debugging information. Problem reported by Joel E. Denny.
1785
1786 2005-08-25 Akim Demaille <akim@epita.fr>
1787
1788 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
1789
1790 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
1791
1792 * data/glr.c (yyrecoverSyntaxError, yyreturn):
1793 Don't invoke destructor on unresolved entries.
1794 * tests/glr-regression.at
1795 (User destructor for unresolved GLR semantic value): New test case.
1796 Problem reported by Joel E. Denny in:
1797 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
1798
1799 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
1800
1801 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
1802 Add strnlen.c.
1803 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
1804 lib-prefix.m4, po.m4.
1805
1806 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
1807 in yydestruct diagnostic, since it might not be an error.
1808 Problem reported by Joel Denny near end of
1809 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1810 * data/lalr1.cc (yyerturn): Likewise.
1811 * data/yacc.c (yyreturn): Likewise.
1812 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
1813
1814 * src/files.c: Remove obsolete FIXME comment.
1815
1816 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
1817 with the other templates, and to fix bogus run-on messages such
1818 as the one reported at the end of
1819 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1820 All callers changed to avoid the newline.
1821 (yyprocessOneStack): Output two lines rather than one, to accommodate
1822 the above change. This changes the debug output format slightly.
1823
1824 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
1825 reported by Joel E. Denny in
1826 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
1827 (trivial change).
1828 * tests/glr-regression.at (Duplicate representation of merged trees):
1829 New test, from Joel E. Denny in:
1830 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
1831 * THANKS: Add Joel E. Denny.
1832
1833 * configure.ac (AC_INIT): Bump to 2.0c.
1834
1835 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
1836
1837 * NEWS: Version 2.0b.
1838
1839 * Makefile.am (SUBDIRS): Put examples before tests, so that
1840 "make check" doesn't finish with "All 1 tests passed".
1841
1842 * tests/regression.at (Token definitions): Don't rely on
1843 AT_PARSER_CHECK for data that contains backslashes. It currently
1844 uses 'echo', and 'echo' isn't portable if its argument contains
1845 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
1846 that the byte '\0xff' is not printable in the C locale; it is,
1847 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
1848 not printable, so use '\0x81' to test.
1849
1850 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
1851 version of GCC, since the macro is used with non-GCC compilers.
1852
1853 Fix core dump reported by Pablo De Napoli in
1854 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
1855 * tests/regression.at (Invalid inputs with {}): New test.
1856 * src/parse-gram.y (token_name): Translate type before using
1857 it as an index.
1858
1859 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
1860 the user's name space. All uses changed to __attribute__
1861 ((__unused__)).
1862 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
1863 Add __attribute__ ((__noreturn__)).
1864
1865 * etc/clcommit: Remove. We weren't using it, and it failed
1866 "make maintainer-distcheck".
1867 * Makefile.maint: Merge from coreutils.
1868 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
1869 (syntax-check-rules): Change list of rules as described below.
1870 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
1871 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
1872 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
1873 (sc_trailing_space): New rules.
1874 (sc_xalloc_h_in_src): Remove.
1875 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
1876 (sc_space_tab, sc_error_exit_success, sc_changelog):
1877 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
1878 (makefile-check, po-check, author_mark_check):
1879 (makefile_path_separator_check, copyright-check):
1880 Use grep -n, to make it easier to find violations.
1881 Use CVS_LIST and CVS_LIST_EXCEPT.
1882 (header_regexp, h_re): Remove.
1883 (dd_c): New macro.
1884 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
1885 (my-distcheck): Use more-modern GCC flags.
1886 (signatures, %.asc): Remove.
1887 (rel-files, announcement): Remove signatures.
1888 Restore old updating code, even though we don't use it, so
1889 that we're the same as coreutils.
1890 (alpha, beta, major): Depend on news-date-check.
1891 Make the upload commands.
1892
1893 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
1894 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
1895 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
1896 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
1897 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
1898 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
1899 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
1900 * tests/sets.at: Likewise.
1901
1902 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
1903 we comment out the Autoconf version number.
1904 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
1905 it's error-prone and "make maintainer-distcheck" rejects it.
1906
1907 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
1908 Indent calls to "error" to pacify "make maintainer-distcheck",
1909 when the calls are not intended to be translated.
1910 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
1911
1912 * src/Makefile.am (DEFS): Use +=, to pacify
1913 "make maintainer-distcheck".
1914 (bison_SOURCES): Add scan-skel.h.
1915 (sc_tight_scope): New rule, from coreutils.
1916
1917 * src/files.c (src_extension, header_extension):
1918 Now static, not extern.
1919 * src/getargs.c (short_options): Likewise.
1920 * src/muscle_tab.c (muscle_table): Likewise.
1921 * src/parse-gram.y (current_class, current_type, current_prec):
1922 Likewise.
1923 * src/reader.c (grammar_end, previous_rule_end): Likewise.
1924 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
1925 * src/main.c (main): Cast bindtextdomain and textdomain calls to
1926 void, to avoid warning when NLS is disabled.
1927 * src/output.c: Include scan-skel.h.
1928 (scan_skel): Remove decl, since scan-skel.h does this.
1929 (output_skeleton):
1930 Indent calls to "error" to pacify "make maintainer-distcheck".
1931 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
1932 * src/reader.h (gram_end, gram_lineno): New decls to pacify
1933 "make maintainer-distcheck".
1934 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
1935 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
1936 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
1937 (skel_lex_destroy, scan_skel): Move these decls to...
1938 * src/scan-skel.h: New file.
1939 * src/uniqstr.c (uniqstr_assert):
1940 Indent calls to "error" to pacify "make maintainer-distcheck".
1941
1942 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
1943 not @VAR@.
1944
1945 * tests/torture.at: Revamp to avoid misuse of atoi that
1946 "make maintainer-distcheck" complained about.
1947
1948 * examples/extexi (message): Don't print a message more than once,
1949 and omit line-number decoration that makes Emacs compile think
1950 that informative messages are worth worrying about.
1951
1952 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
1953
1954 * configure.ac: Update version number.
1955
1956 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
1957 accidentally.
1958 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
1959 autogenerated by the maintainer.
1960 * examples/calc++/.cvsignore: Add *.yy.
1961
1962 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
1963 * lib/bitset_stats.c (bitset_stats_init): Likewise.
1964 * lib/bitsetv.c (bitsetv_alloc): Likewise.
1965
1966 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
1967
1968 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
1969 from maintainer-distcheck about casting the argument of 'free'.
1970
1971 * NEWS: Mention recent yytname changes.
1972 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
1973
1974 * bootstrap: For translations that have not yet been upgraded to
1975 the new runtime-po domain, prime the pump by extracting the
1976 relevant strings from the obsolete translations. This code can be
1977 removed once the bison-runtime domain has been translated by each
1978 team.
1979
1980 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
1981 now that token names are already quoted.
1982
1983 Fix problem reported by Anthony Heading.
1984 * data/glr.c (YYTOKEN_TABLE): New macro.
1985 (yytname): Define if YYTOKEN_TABLE.
1986 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
1987 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
1988 (YYERROR_VERBOSE): Define the same way the other skeletons do.
1989 * src/output.c (prepare_symbols): Output token_table_flag.
1990
1991 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
1992
1993 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
1994 again if the first call fails.
1995
1996 * data/glr.c (yytnamerr): New function.
1997 (yyreportSyntaxError): Use it to dequote most string literals.
1998 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
1999 with other skeletons. All uses changed.
2000 (yytnameerr_): New function.
2001 (yyreport_syntax_error): Use it to dequote most string literals.
2002 * data/yacc.c (yytnamerr): New function.
2003 (yyerrlab): Use it to decode most string literals.
2004 * doc/bison.texinfo (Decl Summary, Calling Convention):
2005 Clarify quoting convention of yytname.
2006 * src/output.c (prepare_symbols): Quote all names. This undoes
2007 the 2005-04-17 change, which is now accomplished (mostly) via
2008 changes in the parsers as described above.
2009 * tests/regression.at (Token definitions, Web2c Actions):
2010 Undo most 2005-04-17 change here, too.
2011
2012 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
2013
2014 Fix more problems reported by twlevo@xs4all.nl.
2015 * tests/cxx-type.at: Don't pipe output of ./types through sed to
2016 remove trailing spaces. This loses the exit status of ./types,
2017 and isn't needed since ./types shouldn't be emitting trailing
2018 spaces.
2019 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
2020 as the stack isn't valid in that case.
2021
2022 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
2023 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
2024 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
2025 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
2026 is used.
2027 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
2028 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
2029 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
2030 Likewise.
2031
2032 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
2033 overly-picky compilers that reject 'char *foo = "bar";'.
2034
2035 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
2036 to FILE * parameter, not to stderr. This fixes a typo introduced
2037 in the 2005-07-12 change.
2038
2039 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
2040 warnings from GCC 4.
2041
2042 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
2043 (yyglrShiftDefer, yysplitStack):
2044 Remove unused parameters b4_pure_formals. All uses changed.
2045 (yyglrShift): Remove unused parameters b4_user_formals.
2046 All uses changed.
2047 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
2048
2049 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
2050
2051 Destructor cleanups and regularization among the three skeletons.
2052 * NEWS: Document the behavior changes.
2053 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
2054 stack before failing, as the cleanup code will do it for us now.
2055 * data/lalr1.cc (yyerrlab): Likewise.
2056 * data/glr.c (yyparse): Pop everything off the stack before
2057 freeing it, so that destructors get called properly.
2058 * data/lalr1.cc (yyreturn): Likewise.
2059 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
2060 This is more consistent.
2061 * doc/bison.texinfo (Destructor Decl): Mention more reasons
2062 why destructors might be called. 1.875 -> 2.1.
2063 (Destructor Decl, Decl Summary, Table of Symbols):
2064 Some English-language cleanups for %destructor.
2065 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
2066 Add output line for destructor of start symbol.
2067 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
2068 because of that same extra output line.
2069
2070 * NEWS: Document minor wording changes in diagnostics of
2071 Bison-generated parsers.
2072 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
2073 Remove unused formals. All uses changed.
2074 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
2075 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
2076 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
2077 Rename yyoverflowab to yyexhaustedlab.
2078 When memory exhaustion occurs during syntax-error reporting,
2079 report it separately rather than in a single diagnostic; this
2080 eases translation.
2081 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
2082 (Memory Exhausted): Renamed from Parser Stack Overflow.
2083 Revamp wording slightly to prefer "memory exhaustion".
2084 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
2085
2086 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
2087
2088 Add i18n support to the GLR skeleton. Partially fix the C++
2089 skeleton; a C++ expert needs to finish this. Remove debugging
2090 msgids; there's little point to having them translated, since they
2091 can be understood only by someone who can read the
2092 (English-language) source code.
2093
2094 Generate runtime-po/bison-runtime.pot automatically, so that we
2095 don't have to worry about garbage getting in that file. We'll
2096 make sure after the next official release that old msgids don't
2097 get lost. See
2098 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
2099
2100 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
2101 Now auto-generated.
2102 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
2103 Fix typos in explanations of the runtime file.
2104 * bootstrap: Change gettext keyword from YYI18N to YY_.
2105 Use standard Makefile.in.in in runtime-po, since we'll arrange
2106 for backward-compatible bison-runtime.po files in a different way.
2107 * data/glr.c (YY_): New macro, from yacc.c.
2108 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
2109 Translate messages intended for users.
2110 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
2111 the wording in the other skeletons. We don't know that the memory
2112 is virtual.
2113 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
2114 Use same method that yacc.c uses.
2115 Don't translate debugging messages.
2116 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
2117 it doesn't work (yet), and requires C++ expertise to fix.
2118 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
2119 Move defn to a more logical place, to be consistent with other
2120 skeletons.
2121 Don't translate debugging messages.
2122 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
2123 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
2124 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
2125 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
2126
2127 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
2128 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
2129 void, not int.
2130 * tests/glr-regression.at (Badly Collapsed GLR States):
2131 Likewise.
2132 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
2133 yylex should return 0 at EOF rather than aborting.
2134
2135 Improve tests for stack overflow in GLR parser.
2136 Problem reported by twlevo@xs4all.nl.
2137 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
2138 All uses removed.
2139 (yyStackOverflow): Just longjmp, but with value 2 so that caller
2140 can handle the problem.
2141 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
2142 (yyparse): New local variable yyresult to record the result.
2143 Use result of setjmp to set it, rather than storing itinto
2144 struct.
2145 (yyDone): Remove label.
2146 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
2147 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
2148 if YYABORT is used).
2149 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
2150 yyparse status; put status > 1 into diagnostic.
2151 Check that status==2 works.
2152 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
2153 Use exit status 3 for failure to open (which shouldn't happen).
2154
2155 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
2156
2157 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
2158 1 on syntax error; just let yyparse do its thing.
2159 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
2160 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
2161 (Exploding the Stack Size with Alloca):
2162 (Exploding the Stack Size with Malloc):
2163 Expect exit status 2, not 1, since the parser is supposed to blow
2164 its stack. Problem reported by twlevo@xs4all.nl.
2165
2166 * data/glr.c (yyparse): Don't assume that the initial calls
2167 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
2168 Print a stack-overflow message and fail instead.
2169 Initialize the line-number information before creating the stack,
2170 so that the stack-overflow message can report line zero safely.
2171
2172 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
2173
2174 Fix problems reported by twlevo@xs4all.nl.
2175 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
2176 (yyuserMerge): Provide a default case if b4_mergers is empty.
2177 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
2178 * tests/glr-regression.at
2179 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
2180 Add casts to pacify C++ compilers.
2181 * tests/glr-regression.at (Improper merging of GLR delayed action
2182 sets): Declare yylex before using it.
2183 * tests/Makefile.am (maintainer-check-g++): Fix a stray
2184 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
2185 test for valgrind; valgrind is independent of g++.
2186 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
2187 for compatibility with POSIX 1003.1-2001 (if running coreutils).
2188 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
2189 Use a destructor, so that we can expand the stack. Change
2190 YYSTYPE to char * so that we can free it. Cast result of malloc.
2191
2192 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2193
2194 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
2195 a valgrind failure. Problem reported by twlevo@xs4all.nl.
2196
2197 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
2198
2199 * PACKAGING: New file, suggested by Bruno Haible and taken from
2200 similar wording in gettext's PACKAGING file.
2201 * NEWS: Mention PACKAGING.
2202 * Makefile.am (EXTRA_DIST): Add PACKAGING.
2203
2204 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
2205
2206 * NEWS: Document recent i18n improvements.
2207 * bootstrap: Get runtime translations into runtime-po.
2208 Create runtime-po files automatically, if possible.
2209 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
2210 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
2211 does not infringe on the user's name space.
2212 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
2213 * doc/bison.texinfo (Internationalization): Revamp the English
2214 and Texinfo syntax a bit, to try to make it clearer.
2215 (Bison Options, Option Cross Key): Mention --print-localedir.
2216 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
2217 YYENABLE_NLS. Quote a bit more.
2218 * runtime-po/.cvsignore: New file.
2219 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
2220 * runtime-po/Rules-quot: Remove; now created by bootstrap.
2221 * runtime-po/quot.sed: Likewise.
2222 * runtime-po/boldquot.sed: Likewise.

2227 * runtime-po/Makevars: Likewise.
2228 * runtime-po/LINGUAS: Likewise.
2229 * runtime-po/de.po: Likewise; we will rely on the translation project
2230 to maintain this, so "bootstrap" should get it.
2231 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
2232 its value.
2233 * src/main.c (main): Bind the bison-runtime domain, too.
2234
2235 2005-07-12 Bruno Haible <bruno@clisp.org>
2236
2237 * data/yacc.c: Include <libintl.h> when NLS is enabled.
2238 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
2239 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
2240 * runtime-po: New directory.
2241 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
2242 $(DOMAIN).pot-update rule, so that old messages are never dropped.
2243 * runtime-po/Rules-quot: New file, copied from po/.
2244 * runtime-po/quot.sed: Likewise.
2245 * runtime-po/boldquot.sed: Likewise.
2246 * runtime-po/en@quot.header: Likewise.
2247 * runtime-po/en@boldquot.header: Likewise.
2248 * runtime-po/insert-header.sin: Likewise.
2249 * runtime-po/remove-potcdate.sin: Likewise.
2250 * runtime-po/Makevars: New file.
2251 * runtime-po/POTFILES.in: New file.
2252 * runtime-po/LINGUAS: New file.
2253 * runtime-po/bison-runtime.pot: New file.
2254 * runtime-po/de.po: New file.
2255 * m4/bison.m4: New file.
2256 * Makefile.am (SUBDIRS): Add runtime-po.
2257 (aclocaldir, aclocal_DATA): New variables.
2258 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
2259 Define aclocaldir.
2260 * src/getargs.c (usage): Document --print-localedir option.
2261 (PRINT_LOCALEDIR_OPTION): New enum item.
2262 (long_options): Add --print-localedir option.
2263 (getargs): Handle --print-localedir option.
2264 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
2265 (Internationalization): New section.
2266
2267 2005-07-12 Akim Demaille <akim@epita.fr>
2268
2269 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
2270 for consistency with the rest of the code.
2271 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
2272 Add separators.
2273
2274 2005-07-12 Akim Demaille <akim@epita.fr>
2275
2276 * src/parse-gram.y: Use %printer instead of YYPRINT.
2277
2278 2005-07-12 Akim Demaille <akim@epita.fr>
2279
2280 * src/symtab.h, src/symtab.c (symbol_print): New.
2281 * src/symlist.h, src/symlist.c (symbol_list_print): New.
2282 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
2283
2284 2005-07-12 Akim Demaille <akim@epita.fr>
2285
2286 * data/glr.c (b4_syncline): Fix (swap) the definitions of
2287 b4_at_dollar and b4_dollar_dollar.
2288
2289 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
2290
2291 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
2292 and Pennello's paper.
2293
2294 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
2295
2296 * data/yacc.c (yyparse): Undo previous patch. Instead,
2297 set yylsp[0] and yyvsp[0] only if the initial action
2298 sets yylloc and yylval, respectively.
2299
2300 * data/yacc.c (yyparse): In the initial action, set
2301 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
2302 This avoids the use of undefined variables if the initial
2303 action does not set yylloc and/or yylval.
2304
2305 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2306
2307 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
2308 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
2309 Remove from CVS. These files are automatically generated.
2310 * examples/extexi: Clarify that this file is now part of Bison,
2311 not GNU M4, and that it works with any POSIX-compatible Awk.
2312 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
2313 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
2314 so that we also get calc++-parser.yy. Geneate it.
2315 Use $(AWK), not gawk, since any conforming Awk will do.
2316 Put comment before action, since older 'make' can't handle comment
2317 in action.
2318 $(BUILT_SOURCES): List all built sources, not just some of them.
2319 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
2320 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
2321 $($(calc_sources_generated)): Remove unnecessary test for existence
2322 of target. (This had a shell syntax error anyway; a stray "x".)
2323 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
2324 calc++-parser.yy.
2325 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
2326
2327 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
2328 implied by the other modules.
2329
2330 2005-07-06 Akim Demaille <akim@epita.fr>
2331
2332 Bind examples/calc++ to the package.
2333 * examples/calc++/Makefile: Remove, replaced by...
2334 * examples/calc++/Makefile.am: ... this new file.
2335 * examples/calc++/test: Remove input.
2336 * examples/calc++/compile: Remove.
2337 * examples/Makefile.am: New.
2338 * configure.ac, Makefile.am: Adjust.
2339 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
2340
2341 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
2342
2343 * data/glr.c (yyFail): Drastically simplify; since the format argument
2344 never had any % directives, we can simply pass it to yyerror.
2345 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
2346 be modified later, as that is the usual style in glr.c.
2347 Problems reported by Paul Hilfinger.
2348
2349 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
2350 and size overflow errors.
2351 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
2352 in case the user prolog sets feature-test macros like _GNU_SOURCE.
2353 (YYSIZEMAX): New macro.
2354 (yystpcpy): New function, taken from yacc.c.
2355 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
2356 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
2357 so that we don't have to maintain their signatures.
2358 (yyFail): Check for buffer overflow, by using vsnprintf rather
2359 than vsprintf. Allocate a bigger buffer if possible.
2360 Report an error if buffer allocation fails.
2361 (yyStackOverflow): New function.
2362 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
2363 the initialization was successful. It might fail if storage was
2364 exhausted.
2365 (yyexpandGLRStack): Add more checks for storage allocation failure.
2366 Use yyStackOverflow to report failures.
2367 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
2368 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
2369 Don't assume stack number fits in int.
2370 (yysplitStack): Check for storage allocation failure.
2371 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
2372 can print diagnostics on storage allocation failure. All callers
2373 changed.
2374 (yyresolveValue): Use yybool for boolean.
2375 (yyreportSyntaxError): Check for size-calculation overflow.
2376 This code is taken from yacc.c.
2377 (yyparse): Check for storage allocation errors when allocating
2378 the initial stack.
2379
2380 2005-07-05 Akim Demaille <akim@epita.fr>
2381
2382 Extract calc++ from the documentation.
2383 * doc/bison.texinfo (Calc++): Add the extraction marks.
2384 * examples/extexi: New, from the aborted GNU Programming 2E.
2385 Separate the different paragraph of a file with empty lines.
2386 * examples/Makefile: Use it to extract the whole calc++ example.
2387
2388 2005-06-24 Akim Demaille <akim@epita.fr>
2389
2390 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
2391 class typedefs.
2392
2393 2005-06-22 Akim Demaille <akim@epita.fr>
2394
2395 * doc/bison.texinfo (C++ Language Interface): First stab.
2396 (C++ Parsers): Remove.
2397
2398 2005-06-22 Akim Demaille <akim@epita.fr>
2399
2400 * data/lalr1.cc (yylex_): Honor %lex-param.
2401
2402 2005-06-22 Akim Demaille <akim@epita.fr>
2403
2404 Start a set of simple examples.
2405 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
2406 * examples/calc++/calc++-driver.hh,
2407 * examples/calc++/calc++-parser.yy,
2408 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
2409 * examples/calc++/compile, examples/calc++/test: New.
2410
2411 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
2412
2413 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
2414 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
2415 which stems from the 2005-05-27 patch.
2416
2417 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2418
2419 * data/glr.c: Modify treatment of unused parameters to permit use
2420 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
2421
2422 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
2423
2424 Fix infringement on user name space reported by Janos Zoltan Szabo.
2425 * data/yacc.c (yyparse): strlen -> yystrlen.
2426
2427 2005-05-30 Akim Demaille <akim@epita.fr>
2428
2429 * data/lalr1.cc (_): New.
2430 Translate the various messages.
2431
2432 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2433
2434 Fix infringement on user name space reported by Bruno Haible.
2435 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
2436 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
2437 the user's name space.
2438 (alloca): Include <stdlib.h> to get it, if it's not built in.
2439 (YYMALLOC, YYFREE): Define only if needed.
2440 (malloc, free): Declare, but only if needed, as this infringes on
2441 the user name space.
2442
2443 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2444
2445 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
2446 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
2447 with %d format.
2448 * lib/ebitset.c (min, max): Undef before defining.
2449 * lib/vbitset.c (min, max): Likewise.
2450 * lib/subpipe.c (create_subpipe): Save local variables in case
2451 vfork clobbers them.
2452
2453 2005-05-24 Bruno Haible <bruno@clisp.org>
2454
2455 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
2456 error message syntax used by gcc-4.0.
2457
2458 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
2459
2460 * README: Mention m4 1.4.3. Remove obsolete advice about
2461 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
2462
2463 * bootstrap: Remove workaround for problem I encountered with
2464 gettext 0.14.1; it seems to be fixed now.
2465
2466 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
2467
2468 * NEWS: Version 2.0a.
2469
2470 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
2471 the previous change.
2472
2473 Various maintainer cleanups.
2474 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
2475 conftest*, for benefit of CVS commands run at the same time as
2476 "configure". Add build-aux, since "bootstrap" now creates it and
2477 its subfiles.
2478 * Makefile.cfg (move_if_change): Remove.
2479 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
2480 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
2481 (po_repo, do-po-update, po-update, wget_files, get-targets):
2482 (config.guess-url_prefix, config.sub-url_prefix):

2485 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
2486 Remove.
2487 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
2488 this is now the recommended name.
2489 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
2490 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
2491 ylwrap. These files now go into build-aux.
2492 * config/move-if-change: Remove.
2493 * config/prev-version.txt: Bump from 1.75 to 2.0.
2494
2495 * bootstrap: Add stdio-safer, unistd-safer modules.
2496 Remove m4/glibc2.m4 (introduced by latest gnulib, but
2497 we don't need it).
2498 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
2499 fopen-safer.c, stdio-safer.h, unistd-safer.h.
2500 * lib/subpipe.c: Include "unistd-safer.h".
2501 (create_subpipe): Make sure all the newly-created
2502 file descriptors are > 2, so that diagnostics don't
2503 get sent down them (which might cause Bison to hang, in theory).
2504 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
2505 * src/files.c (xfopen): Use fopen_safer, not fopen.
2506
2507 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
2508 yesterday's yacc.c fix.
2509
2510 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
2511
2512 * data/glr.c, data/lalr1.cc: Update copyright date.
2513
2514 Fix a destructor bug reported by Wolfgang Spraul in
2515 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
2516 * data/yacc.c (yyabortlab): Don't call destructor, and
2517 don't set yychar to EMPTY.
2518 (yyoverflowlab): Don't call destructor.
2519 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
2520 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
2521 since we no longer output the message "discarding lookahead token
2522 end of input ()".
2523
2524 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2525
2526 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
2527 fix a small glitch in debugging output.
2528 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
2529 after YY_SYMBOL_PRINT where needed.
2530
2531 (struct yyGLRState): Add some comments.
2532 (struct yySemanticOption): Add some comments.
2533 (union yyGLRStackItem): Add comment.
2534
2535 (yymergeOptionSets): Correct this to properly perform the union,
2536 avoiding infinite reported by Michael Rosien.
2537 Update comment.
2538
2539 * tests/glr-regression.at: Add test for GLR merging error reported
2540 by M. Rosien.
2541

2580 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
2581
2582 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
2583 Problem reported by Ralf Menzel.
2584
2585 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2586
2587 * tests/actions.at: Test that stack overflow invokes destructors.
2588 From Marcus Holland-Moritz.
2589 * data/yacc.c (yyerrlab): Move the code that destroys the stack
2590 from here....
2591 (yyreturn): to here. That way, destructors are called properly
2592 even if the stack overflows, or the user calls YYACCEPT or
2593 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
2594 (yyoverflowlab): Destroy the lookahead.
2595
2596 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
2597
2598 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
2599
2600 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
2601
2602 * NEWS: Bison-generated C parsers no longer quote literal strings
2603 associated with tokens.
2604 * src/output.c (prepare_symbols): Don't escape strings,
2605 since users don't want to see C escapes.
2606 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
2607 in diagnostics.
2608 * tests/input.at (Torturing the Scanner): Likewise.
2609 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
2610
2611 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
2612
2613 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
2614 the data size is known to be too small and we can't increase it.
2615 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
2616
2617 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
2618
2619 * src/parse-gram.y: Include quotearg.h.
2620 (string_as_id): Quote $1 before using it as a key, since the
2621 lexer no longer quotes it for us.
2622 (string_content): Don't strip quotes, since lexer no longer
2623 quotes it for us.
2624 * src/scan-gram.l: Include quotearg.h.
2625 ("\""): Omit quote.
2626 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
2627 a key, since the rest of the lexer doesn't quote it.
2628 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
2629 * tests/regression.at (Token definitions): Check for backslashes
2630 in token strings.
2631
2632 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
2633 (YYSIZE_T): Define to unsigned long int when using an older compiler.
2634 (yyparse): Revamp code to generate long syntax error message, to
2635 make it easier to translate, and to avoid problems with arithmetic
2636 overflow. Change "virtual memory" to "memory" in diagnostic, since
2637 we don't know whether the memory is virtual.
2638
2639 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2640
2641 * NEWS: Bison-generated C parsers now use the _ macro to
2642 translate strings.
2643 * data/yacc.c (_) [!defined _]: New macro.
2644 All English strings wrapped inside this macro.
2645 * doc/bison.texinfo (Bison Parser): Document _.
2646 * po/POTFILES.in: Include src/parse-gram.c, since it now
2647 includes translateable strings that parse-gram.y doesn't.
2648
2649 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
2650
2651 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
2652 reverting the 2004-10-11 change to this function.
2653 (symbol_check_alias_consistency): Don't call symbol_type_set
2654 if the type name is already correct.
2655 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
2656
2657 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
2658
2659 * tests/regression.at (Token definitions): Don't use a token named
2660 c, as that generates a "#define c ..." that runs afoul of buggy
2661 stdlib.h that uses the identifier c as a member of struct
2662 drand48_data. Problem reported by Horst Wente.
2663
2664 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
2665
2666 * bootstrap: Change translation URL from
2667 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
2668 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
2669 redirection glitches. Problem reported by twlevo@xs4all.nl.
2670
2671 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
2672
2673 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
2674 after operands; POSIX says this isn't portable for the c99 command.
2675
2676 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
2677
2678 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
2679 immediately if a data overrun has occurred; this may help us track
2680 down what may be a spurious failure on MacOS.
2681
2682 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
2683
2684 Respond to problems reported by twlevo@xs4all.nl.
2685
2686 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
2687
2688 * src/vcg.h: Comment fix.
2689 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
2690 (G_CMAX): Change to -1 instead of INT_MAX.
2691
2692 * data/yacc.c (yyparse): Omit spaces before #line.
2693
2694 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
2695
2696 * src/tables.c (state_number_to_vector_number): Put it inside an
2697 "#if 0", since it's not currently used. Problem reported by
2698 Roland McGrath.
2699
2700 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
2701
2702 * src/output.c (escaped_output): Renamed from
2703 escaped_file_name_output, since we now use it for symbol tags as
2704 well. All uses changed.
2705 (symbol_destructors_output, symbol_printers_output):
2706 Escape symbol tags too.
2707 Problem reported by Matyas Forstner in
2708 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
2709
2710 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
2711 not needed.
2712 * src/output.c (user_actions_output, token_definitions_output,
2713 symbol_destructors_output, symbol_printers_output): Likewise.
2714 * src/reader.c (prologue_augment): Likewise.
2715 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
2716
2717 * src/vcg.c (output_edge): Don't quote linestyle arg.
2718 Problem reported by twlevo@xs4all.nl.
2719
2720 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
2721
2722 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
2723 example, reported by Derek M Jones. Also, make the example even
2724 more outrageous, to better illustrate how bad the problem is.
2725
2726 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
2727
2728 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
2729 putsym. Typo reported by Sebastian Piping.
2730
2731 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2732
2733 * doc/bison.texinfo (Language and Grammar): some -> same
2734 (Epilogue): int he -> in the
2735 Typos reported by Sebastian Piping via Justin Pence.
2736
2737 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2738
2739 * tests/glr-regression.at (Improper handling of embedded actions
2740 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
2741 embedded actions and $-N in GLR parsers", work around an Autoconf bug
2742 with dollar signs in test names.
2743 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
2744 for a similar reason.
2745
2746 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2747
2748 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
2749 wants to redefine G_VIEW.
2750
2751 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
2752
2753 * src/vcg.c (get_view_str): Remove case for normal_view.
2754 Problem reported by twlevo@xs4all.nl.
2755
2756 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
2757
2758 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
2759 Problem reported by twlevo@xs4all.nl.
2760
2761 * doc/bison.texinfo: Change @dircategory from "GNU programming
2762 tools" to "Software development". Requested by Richard Stallman
2763 via Karl Berry.
2764
2765 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
2766
2767 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
2768 Problem reported by twlevo@xs4all.nl.
2769
2770 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2771
2772 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
2773 keyword; it's not needed with modern compilers, and it doesn't
2774 affect correctness with older compilers. Suggested by
2775 twlevo@xs4all.nl.
2776
2777 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
2778
2779 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
2780 gcc -Wswitch-default.
2781 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
2782 * data/yacc.c (yyparse): Likewise.
2783
2784 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
2785
2786 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
2787 already. Let config.h define any nonstandard values.
2788
2789 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
2790
2791 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
2792 for the benefit of slower hosts. Problem reported by
2793 Nelson H. F. Beebe.
2794
2795 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
2796
2797 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
2798 being defined and not used.
2799 * data/lalr1.cc (yyparse): Likewise.
2800 Use "if (false)" rather than "if (0)".
2801
2802 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
2803
2804 * TODO: Mention that we should allow NUL bytes in tokens.
2805
2806 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
2807
2808 * src/scan-skel.l (<<EOF>>): Don't close standard output.
2809 Problem reported by Hans Aberg.
2810
2811 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
2812
2813 * src/getargs.c (version): Happy new year; update overall
2814 program copyright date from 2004 to 2005.
2815
2816 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
2817 Problem reported by Hans Aberg.
2818 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
2819 (Output file names.): Add a test for the case when standard output
2820 is closed.
2821
2822 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
2823
2824 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
2825 to fix an oversight in the Bison 2.0 manual.
2826
2827 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
2828
2829 * NEWS: Version 2.0. Reformat the existing news items since
2830 1.875, so that related items are grouped together.
2831 * configure.ac (AC_INIT): Bump version to 2.0.
2832 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
2833
2834 * tests/torture.at (Exploding the Stack Size with Alloca): Set
2835 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
2836 otherwise, we're not testing alloca. Unfortunately there's no
2837 simple way to consult HAVE_ALLOCA here.
2838
2839 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
2840 for yymsg, too.
2841
2842 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
2843 hand. This avoids a warning about comparing int to size_t when
2844 GCC warnings are enabled.
2845
2846 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
2847
2848 * NEWS: Bison-generated parsers no longer default to using the
2849 alloca function (when available) to extend the parser stack, due
2850 to widespread problems in unchecked stack-overflow detection.
2851 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
2852 responsibility to set it to a positive value. This lets the user
2853 specify a value that is not a preprocessor constant.
2854 * data/yacc.c (YYMAXDEPTH): Likewise.
2855 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
2856 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
2857 to be a compile-time constant. However, explain the constraints on it.
2858 Also, explain the constraints on YYINITDEPTH.
2859 (Table of Symbols): Explain that alloca is no longer the default.
2860 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
2861 to 1.
2862
2863 * doc/bison.texinfo (Location Default Action): Mention that n must
2864 be zero when k is zero. Suggested by Frank Heckenbach.
2865
2866 2004-12-22 Akim Demaille <akim@epita.fr>
2867
2868 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
2869 (parser::state_type, parser::semantic_type, parser::location_type):
2870 Private, not public.
2871 (parser::parse): Return ints, not bool.
2872 Returning a bool introduces a problem: 0 corresponds to false, and
2873 it seems weird to return false on success. Returning true changes
2874 the conventions for yyparse.
2875 Alternatively we could return void and send an exception.
2876 There is no clear consensus (yet?).
2877 (state_stack, semantic_stack, location_stack): Rename as...
2878 (state_stack_type, semantic_stack_type, location_stack_type): these.
2879 Private, not public.
2880 * tests/c++.at: New.
2881 * tests/testsuite.at, tests/Makefile.am: Adjust.
2882
2883 2004-12-21 Akim Demaille <akim@epita.fr>
2884
2885 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
2886
2887 2004-12-21 Akim Demaille <akim@epita.fr>
2888
2889 Don't impose std::string for filenames.
2890
2891 * data/lalr1.cc (b4_filename_type): New.
2892 (position::filename): Use it.
2893 (parser.hh): Move the inclusion of stack.hh and location.hh below
2894 the user code, so that needed headers for the filename type can be
2895 included first.
2896 Forward declare them before the user code.
2897 * tests/Makefile.am (check-local, installcheck-local): Pass
2898 TESTSUITEFLAGS to the TESTSUITE.
2899
2900 2004-12-20 Akim Demaille <akim@epita.fr>
2901
2902 Use more STL like names: my_class instead of MyClass.
2903
2904 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
2905 (SemanticStack, SemanticType, StateStack, StateType)
2906 (TokenNumberType, Stack, Slice, Traits, Parser::location)
2907 (Parser::value): Rename as...
2908 (location_stack, location_type, rhs_number_type, semantic_stack)
2909 (semantic_type, state_stack, state_type, token_number_type, stack)
2910 (slice, traits, parser::yylloc, parser::yylval): these.
2911
2912 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
2913
2914 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
2915
2916 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
2917 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
2918
2919 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
2920
2921 Remove uses of 'short int' and 'unsigned short int'. This raises
2922 some arbitrary limits. It uses more memory but nowadays that's
2923 not much of an issue.
2924
2925 This change does not affect the generated parsers; that's a different
2926 task, as some users will want to conserve memory there.
2927
2928 Ideally we should use size_t to represent all object counts, and
2929 something like ptrdiff_t to represent signed differences of object
2930 counts; but that will require more code-cleanup than I have the
2931 time to do right now.
2932
2933 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
2934 Use size_t, not int or short int, to count objects.
2935 * src/closure.c (nritemset, closure): Likewise.
2936 * src/closure.h (nritemset, closure): Likewise.
2937 * src/nullable.c (nullable_compute): Likewise.
2938 * src/print.c (print_core): Likewise.
2939 * src/print_graph.c (print_core): Likewise.
2940 * src/state.c (state_compare, state_hash): Likewise.
2941 * src/state.h (struct state): Likewise.
2942 * src/tables.c (default_goto, goto_actions): Likewise.
2943
2944 * src/gram.h (rule_number, rule): Use int, not short int.
2945 * src/output.c (prepare_rules): Likewise.
2946 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
2947 errs, reductions): Likewise.
2948 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
2949 Likewise.
2950 * src/tables.c (vector_number, tally, action_number,
2951 ACTION_NUMBER_MINIMUM): Likewise.
2952 * src/output.c (muscle_insert_short_int_table): Remove.
2953
2954 2004-12-17 Akim Demaille <akim@epita.fr>
2955
2956 * data/lalr1.cc: Extensive Doxygenation.
2957 (error_): Rename as...
2958 (error): this, since it is visible to the user.
2959 Adjust callers.
2960 (Parser::message): Now an automatic variable from...
2961 (Parser::yyreport_syntax_error_): here.
2962 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
2963 Parser::error.
2964 * tests/input.at: Escape $.
2965
2966 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
2967
2968 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
2969 Parenthesize rhs to avoid obscure problems with mistakes like
2970 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
2971 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2972 b4_rhs_location): Likewise.
2973 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2974 b4_rhs_location): Likewise.
2975
2976 2004-12-16 Akim Demaille <akim@epita.fr>
2977
2978 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
2979 yacc.c: be sure to stay within yycheck_.
2980 * tests/actions.at: Re-enable C++ tests.
2981
2982 2004-12-16 Akim Demaille <akim@epita.fr>
2983
2984 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
2985 real.
2986
2987 2004-12-16 Akim Demaille <akim@epita.fr>
2988
2989 Use #define to handle the %name-prefix.
2990
2991 * data/glr.c, data/yacc.c: Comment changes.
2992 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
2993 so that one can refer to yylex in the parser file, and have it
2994 renamed, as is the case with other skeletons.
2995
2996 2004-12-16 Akim Demaille <akim@epita.fr>
2997
2998 Move lalr1.cc internals into yy*.

3002 (pgoto_, defgoto_, table_, table_ninf_, check_, stos_, r1_, r2_)
3003 (name_, rhs_, prhs_, rline_, token_number_, eof_, last_, nnts_)
3004 (empty_, final_, terror_, errcode_, ntokens_)
3005 (user_token_number_max_, undef_token_, n_, len_, state_, nerrs_)
3006 (looka_, ilooka_, error_range_, nerrs_):
3007 Rename as...

3016 these.
3017
3018 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
3019
3020 Fix some problems reported by twlevo at xs4all.
3021 * src/symtab.c (symbol_new): Report an error if the input grammar
3022 contains too many symbols. This is better than calling abort() later.
3023 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
3024 (struct node, struct graph):
3025 Rename member expand to stretch. All uses changed.
3026 (struct graph): Remove member layoutalgorithm. All uses removed.
3027 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
3028 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
3029 All uses changed.

3031
3032 2004-12-15 Akim Demaille <akim@epita.fr>
3033
3034 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
3035 Add more Doxygen comments.
3036 (symprint_, stack_print_, reduce_print_, destruct_, pop)
3037 (report_syntax_error_, translate_): Rename as...
3038 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
3039 (yypop_, yyreport_syntax_error_, yytranslate_): this.
3040
3041 2004-12-15 Akim Demaille <akim@epita.fr>
3042
3043 * data/lalr1.cc (lex_): Rename as...
3044 (yylex_): this.
3045 Move the trace here.
3046 Take the %name-prefix into account.
3047 Reported by Alexandre Duret-Lutz.
3048
3049 2004-12-15 Akim Demaille <akim@epita.fr>
3050
3051 Simplify the C++ parser constructor.
3052
3053 * data/lalr1.cc (debug_): Rename as...
3054 (yydebug_): so that the parser's internals are always in the yy*
3055 pseudo namespace.
3056 Adjust uses.
3057 (b4_parse_param_decl): Remove the leading comma as it is now only
3058 called as unique argument list.
3059 (Parser::Parser): Remove the constructor accepting a location and
3060 an initial debugging level.
3061 Remove from the other ctor the argument for the debugging level.
3062 (debug_level_type, debug_level, set_debug_level): New.
3063
3064 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
3065 constructor calls.
3066
3067 2004-12-15 Akim Demaille <akim@epita.fr>
3068
3069 Remove b4_root related material: failure experiment
3070 (which goal was to allow to derive from a class).
3071
3072 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
3073 definitions and uses.
3074
3075 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
3076
3077 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
3078 not 2, since it's not portable to subtract 1 from the start of an
3079 array. The new item 0 is never set or used. All uses changed.
3080
3081 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
3082 the default definition of YYLLOC_DEFAULT. Problem reported
3083 by Frank Heckenbach.
3084
3085 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
3086
3087 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
3088 the normal case and one for the error case. Just use the
3089 first one uniformly. Problem reported by Frank Heckenbach.
3090 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
3091 use exactly the same macro in both places.
3092 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
3093 so that the normal-case YYRHSLOC works for the error case too.
3094 All uses changed.
3095 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
3096 (YYLLOC_DEFAULT): Use the same macro as glr.c.
3097 * doc/bison.texinfo (Location Default Action): Don't claim that
3098 we have an array of locations. Use the same macro for both glr
3099 and lalr parsers. Mention YYRHSLOC. Mention what happens when
3100 the index is 0.
3101
3102 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
3103
3104 * HACKING: Update email addresses to send announcements to.

3111 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
3112
3113 * src/scan-skel.l: Include "complain.h", for "fatal".
3114
3115 * src/relation.h (relation_print, relation_digraph):
3116 Relation sizes are of type relation_node, not size_t (this is
3117 merely a doc fix, since the two types are equivalent).
3118 (relation_transpose): Relation sizes are of type relation_node,
3119 not int.
3120 * src/relation.c: Likewise.
3121 (top, infinity): Now of type relation_node, not int.
3122 (traverse, relation_transpose): Use relation_node, not int.
3123
3124 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
3125 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
3126 (yyparse): Remove unused local introduced in 2004-10-25 patch.
3127
3128 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
3129 specifying whether the test should be skipped. Use it tp
3130 specify that the [%defines %skeleton "lalr1.cc"] tests currently
3131 fail on some hosts, and should be skipped.
3132
3133 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
3134
3135 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
3136 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
3137 unless otherwise specified below.
3138
3139 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
3140 to allocate kernel_base, kernel_items, kernel_size, since
3141 they needn't be initialized to 0.
3142 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
3143 * src/closure.c (new_closure): Likewise, for itemset.
3144 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
3145 * src/lalr.c (set_goto_map): Likewise, for temp_map.
3146 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
3147 (build_relations): Likewise for edge, states1, includes.
3148 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
3149 * src/reader.c (packgram): Likewise, for ritem, rules.

3152 (relation_transpose): Likewise for new_R, end_R.
3153 * src/symtab.c (symbols_token_translations_init): Likewise for
3154 token_translations.
3155 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
3156 (token_actions): Likewise for yydefact, actrow, conflrow,
3157 conflict_list.
3158 (save_column): Likewise for froms[symno], tos[symno].
3159 (goto_actions): Likewise for state_count.
3160 (pack_table): Likewise for base, pos, check.
3161 (tables_generate): Likewise for width.
3162
3163 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
3164 for initial core. Just have a separate core, so we needn't worry
3165 about whether kernel_size and kernel_base are initialized.
3166
3167 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
3168 kernel_size, kernel_items): Remove unnecessary initialization.
3169 * src/conflicts.c (conflicts): Likewise.
3170 * src/derives.c (derives): Likewise.
3171 * src/muscle_tablc (muscle_insert): Likewise.
3172 * src/relation.c (relation_digraph): Likewise.
3173 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
3174 conflrow, conflict_table, conflict_list, table, check):
3175 Likewise.
3176
3177 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
3178 This is because all callers pass unsigned int.
3179 * src/closure.h (new_closure): Likewise.
3180
3181 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
3182 (build_relations): Initialize includes[i] in all cases.
3183 * src/reader.c (packgram): Always initialize rules[ruleno].prec
3184 and rules[ruleno].precsym. Initialize members in order.
3185 * src/relation.c (relation_transpose): Always initialize new_R[i]
3186 and end_R[i].
3187 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
3188
3189 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
3190 conflict_list[0] was always 0, but now it isn't initialized.
3191
3192 * src/table.c (table_grow): When conflict_table grew, the grown
3193 area wasn't cleared. Fix this.
3194
3195 * lib/.cvsignore: Add strdup.c, strdup.h.
3196 * m4/.cvsignore: Add strdup.m4.
3197
3198 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
3199
3200 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
3201 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
3202 GOTO_NUMBER_MAXIMUM, since we occasionally compute
3203 ngotos + 1 without checking for overflow.
3204 (build_relations): Use END_NODE, not -1, to denote end of edges.
3205 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
3206 build_relations): Use goto_number, not int, for goto numbers.
3207 * src/tables.c (save_column, default_goto): Likewise.
3208
3209 2004-11-23 Akim Demaille <akim@epita.fr>
3210
3211 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
3212 of #defining from yystype.
3213 Don't typedef yystype, C++ does not need it.
3214 This lets it possible to forward declare it as union.
3215
3216 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
3217
3218 * bootstrap (gnulib_modules): Add extensions.
3219 Problem reported by Jim Meyering.
3220
3221 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
3222
3223 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
3224 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
3225 src/system.h, src/tables.c: XFREE -> free, to accommodate
3226 recent change to gnulib xalloc.h.
3227 Problem reported by Jim Meyering.
3228
3229 2004-11-17 Akim Demaille <akim@epita.fr>
3230
3231 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
3232
3233 2004-10-28 Akim Demaille <akim@epita.fr>,
3234 Alexandre Duret-Lutz <adl@gnu.org>
3235
3236 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
3237 changes.
3238 (YYCDEBUG): Adjust.
3239 Use it instead of cdebug_.
3240 (Parser::debug_stream, Parser::set_debug_stream): New.
3241 (Parser::symprint_): Define cdebug_ for temporary backward
3242 compatibility.
3243 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
3244 debug_stream ().
3245
3246 2004-11-17 Akim Demaille <akim@epita.fr>
3247
3248 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
3249 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
3250 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
3251 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
3252
3253 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
3254
3255 * data/glr.c (yyloc_default): Remove; not used.
3256 Problem reported by Frank Heckenbach.
3257
3258 2004-10-25 Akim Demaille <akim@epita.fr>
3259
3260 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
3261 Introduce another definition to address simple location arrays.
3262 (yyGLRStack): New member: yyerror_range.
3263 (yyrecoverSyntaxError, yyparse): Update it.
3264 (yyrecoverSyntaxError): Use it when shifting the error token to
3265 have an accurate range, equivalent to the one computed by both
3266 yacc.c and lalr1.cc.
3267 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
3268 that column numbers start at column 0, as per GNU Coding
3269 Standards, the others tests, and the doc.
3270 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
3271 Adjust to the above change (first column is 0).
3272 And adjust the location of the "<error>", now covering the whole
3273 line.
3274
3275 2004-10-22 Akim Demaille <akim@epita.fr>
3276 and Paul Eggert <eggert@cs.ucla.edu>
3277
3278 Remove some arbitrary limits on goto numbers and relations.
3279 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
3280 initial values, since they're never used.
3281 (set_goto_map): ngotos is now unsigned, so test for overflow
3282 by seeing whether it wraps around to zero.
3283 * src/lalr.h (goto_number): Now size_t, not short int.
3284 (GOTO_NUMBER_MAXIMUM): Remove.
3285 * src/relation.c (relation_print, traverse, relation_transpose):
3286 Check for END_NODE rather than looking at sign.
3287 * src/relation.h (END_NODE): New macro.
3288 (relation_node): Now size_t, not short int.
3289
3290 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
3291
3292 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
3293 keyword, not an identifier. Problem reported by Baron Schwartz in
3294 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
3295
3296 2004-10-11 Akim Demaille <akim@epita.fr>
3297
3298 * src/symtab.c (symbol_check_alias_consistency): Also check
3299 type names, destructors, and printers.
3300 Reported by Alexandre Duret-Lutz.
3301 Recode the handling of associativity and precedence in terms
3302 of symbol_precedence_set.
3303 Accept no redeclaration at all, not even equal to the previous
3304 value.
3305 (redeclaration): New.
3306 Use it to factor redeclaration complaints.
3307 (symbol_make_alias): Don't set the type of the alias, let
3308 symbol_check_alias_consistency do it as for other features.
3309 * src/symtab.h (symbol): Add new member prec_location, and
3310 type_location.
3311 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
3312 * tests/input.at (Incompatible Aliases): New.
3313
3314 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
3315
3316 .cvsignore fixes to accommodate gnulib changes,
3317 and the practice of naming build directories "_build".
3318 * .cvsignore: Add "_*". Sort.
3319 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
3320 * m4/.cvsignore: Add "*_gl.m4".
3321
3322 2004-10-06 Akim Demaille <akim@epita.fr>
3323
3324 * src/parse-gram.y (add_param): Fix the truncation of trailing
3325 spaces.
3326
3327 2004-10-05 Akim Demaille <akim@epita.fr>
3328
3329 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
3330 whether the reducion was empty or not. This leaves room to
3331 improve the use of YYLLOC_DEFAULT in such a case.
3332 lalr1.cc is still experimental, so changing this is acceptable.
3333 And finally, there are probably not many users who changed the
3334 handling of locations in GLR, so changing is admissible too.
3335
3336 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
3337 empty reduction, set @$ to an empty location ending the previously
3338 stacked symbol.
3339 Adjust uses to make sure the code is triggered on empty
3340 reductions.
3341 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
3342 expected output: empty reductions have empty locations.
3343
3344 2004-09-29 Akim Demaille <akim@epita.fr>
3345
3346 * data/lalr1.cc: Move towards a more standard C++ coding style
3347 for templates: Class < T > -> Class<T>.
3348
3349 2004-09-29 Akim Demaille <akim@epita.fr>
3350
3351 * data/lalr1.cc: Reinstall the former ctor, for sake of
3352 compatibility, but warn it will be removed.
3353 Move towards a more standard C++ coding style (i.e., type *var ->
3354 type* var).
3355
3356 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
3357
3358 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
3359 since it's less likely to work if NULs are involved in the future.
3360
3361 2004-09-27 Akim Demaille <akim@epita.fr>
3362
3363 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
3364
3365 2004-09-27 Akim Demaille <akim@epita.fr>
3366
3367 * data/lalr1.cc (b4_parse_param_decl_1): New.
3368 (b4_parse_param_decl): Use it to have different names between attribute
3369 and argument names.
3370 (b4_cc_constructor_call): Likewise.
3371
3372 2004-09-24 Akim Demaille <akim@epita.fr>
3373
3374 * src/parse-gram.y (add_param): Strip the leading and trailing
3375 blanks from a formal argument declaration.
3376 (YY_LOCATION_PRINT): New.
3377
3378 2004-09-24 Akim Demaille <akim@epita.fr>
3379
3380 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
3381 after the location.
3382
3383 2004-09-24 Akim Demaille <akim@epita.fr>
3384
3385 * doc/bison.texinfo (Table of Symbols): Sort.
3386
3387 2004-09-21 Akim Demaille <akim@epita.fr>
3388
3389 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
3390 the useless parentheses.
3391 Suggested by Paul Eggert.
3392
3393 2004-09-20 Akim Demaille <akim@epita.fr>
3394
3395 Let the initial-action act on the look-ahead, and use it for the
3396 "initial push" (corresponding to an hypothetical beginning-of-file).
3397 And let lalr1.cc honor %initial-action.
3398
3399 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
3400 example.
3401 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
3402 (Parser::Parser): Remove the ctor that used to initialize it.
3403 (Parser::parse): Like in the other skeletons, issue the "starting
3404 parse" message before any action.
3405 Honor %initial-action.
3406 Initialize the stacks with the lookahead.
3407 * data/yacc.c: Let $$ and @$ in %initial-action designate the
3408 look-ahead.
3409 Push them in the stacks.
3410 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
3411
3412 2004-09-20 Akim Demaille <akim@epita.fr>
3413
3414 * doc/bison.texinfo (Initial Action Decl): New.
3415
3416 2004-09-20 Akim Demaille <akim@epita.fr>
3417
3418 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
3419 clearer criterion to define it.
3420 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
3421 When reducing on an empty RHS, use the latest stacked location as
3422 location.
3423 yylloc is not always available.
3424 * data/glr.c: Likewise.
3425 Also, honor initial-actions.
3426
3427 2004-09-20 Akim Demaille <akim@epita.fr>
3428
3429 * data/yacc.c (YY_LOCATION_PRINT): New.
3430 Define when we know YYLTYPE's structure, i.e., when the default
3431 YYLLOC_DEFAULT is used.
3432 * data/c.m4 (b4_yysymprint_generate): Use it.
3433 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
3434 value of the result.
3435 (error_start_): Replace with...
3436 (error_range_): this location array.
3437 This allows to replace code relying on the implementation of
3438 locations by portable code.
3439 * data/yacc.c (yylerrsp): Replace with...
3440 (yyerror_range): this.
3441 Every time a token is popped, update yyerror_range[0], to have an
3442 accurate location for the error token.
3443 * data/glr.c (YY_LOCATION_PRINT): New.
3444 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
3445 deference a pointer.
3446 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
3447 report the location in %printers.
3448
3449 * src/scan-skel.l: Instead of abort, report error messages to ease
3450 understanding skeleton scanning failures.
3451
3452 2004-09-16 Akim Demaille <akim@epita.fr>
3453
3454 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
3455 (iterator, const_iterator): these, to be more in the C++ spirit.
3456 Also, return reverse iterators so that when displaying the stack
3457 we display its bottom first.
3458 (Parser::stack_print_, Parser::reduce_print_): Match the messages
3459 from yacc.c.
3460 We should probably use vector here though.
3461
3462 2004-09-16 Akim Demaille <akim@epita.fr>
3463
3464 Have more complete shift traces.
3465
3466 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
3467 to report Shifts instead of ad hoc YYDPRINTF invocations,
3468 including for the error token.
3469 * data/lalr1.cc (symprint_): Output the location.
3470 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
3471 output the location within the %printer.
3472 Activate GLR tests, at least to make sure they compile properly.
3473 They still don't pass though.
3474 * tests/calc.at: Adjust expect verbose output, since now "Entering
3475 state..." is on a different line than the "Shifting" message.
3476
3477 2004-09-08 Akim Demaille <akim@epita.fr>
3478
3479 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
3480 Bison directive from the Bison file to the invocation of this
3481 macro, so that these directives are passed to
3482 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3483 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3484 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3485 the extra Bison directives instead of the whole series.
3486 Change the grammar so that there are recoverable errors, and
3487 unrecoverable errors. Now we can have the parser give up before
3488 consuming the whole input. As a result we now can observe that
3489 the lookahead is freed when needed.
3490 Change the parser source to parse argv[1] instead of a hard coded
3491 string.
3492 Simplify yylex, and give a value and location to EOF.
3493 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3494 passed directives already coded in the file.
3495 Add some tests to check the location of "error".
3496 For some tests, the C++ parser is correct, and not yacc.c.
3497 For other tests, they provide different, but unsatisfying, values,
3498 so keep the C++ value so that at least one parser is "correct"
3499 according to the test suite.
3500 (Actions after errors): Remove, this is subsumed by the
3501 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
3502
3503 2004-09-06 Akim Demaille <akim@epita.fr>
3504
3505 * data/lalr1.cc: Adjust the indentation of the labels.
3506 (Parser::pop): New.
3507 Use it.
3508
3509 2004-09-06 Akim Demaille <akim@epita.fr>
3510
3511 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
3512 argument, an informative message.
3513 Call YY_SYMBOL_PRINT.
3514 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
3515 * data/lalr1.cc (destruct_): Likewise.
3516 In addition, no longer depend on b4_yysymprint_generate and
3517 b4_yydestruct_generate to generate these functions, do it "by
3518 hand".
3519
3520 2004-09-03 Akim Demaille <akim@epita.fr>
3521
3522 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
3523 invoked, yydestruct the lookahead.
3524 * tests/calc.at (Calculator $1): Update the expected lengths of
3525 traces: there is an added line for the discarded lookahead.
3526 * doc/bison.texinfo (Destructor Decl): Some rewording.
3527 Define "discarded" symbols.
3528
3529 2004-09-02 Akim Demaille <akim@epita.fr>
3530
3531 * data/lalr1.cc (translate_, destruct_): No reason to be static.
3532
3533 2004-09-02 Akim Demaille <akim@epita.fr>
3534
3535 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
3536 (YYDSYMPRINTF): Rename as...
3537 (YY_SYMBOL_PRINT): this.
3538 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
3539 two.
3540 Use it instead of direct symprint_ calls.
3541 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
3542 one.
3543
3544 2004-09-02 Akim Demaille <akim@epita.fr>
3545
3546 * data/lalr1.cc (b4_yysymprint_generate): New.
3547 (symprint_): New member function, defined when YYDEBUG.
3548 Use it consistently instead of token/nterm debugging output by
3549 hand.
3550 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
3551 %printer calls to use cdebug_ when using lalr1.cc.
3552
3553 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
3554
3555 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
3556 with #ifdef YYDEBUG.
3557
3558 2004-08-26 Akim Demaille <akim@epita.fr>
3559
3560 * doc/bison.texinfo (Implementing Loops): Rename as...
3561 (Implementing Gotos/Loops): this.
3562
3563 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
3564
3565 Adjust to latest gnulib.
3566 * bootstrap (gnulib_modules): Add xalloc-die.
3567 Set LC_ALL=C so that file names sort consistently.
3568 Prefer the gnulib copies of gettext.m4, glibc21.m4,
3569 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
3570 uintmax_t.m4, ulonglong.m4.
3571 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
3572 po.m4 since we are now using _gl.m4 instead.
3573
3574 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
3575
3576 * src/scan-action.l: Remove. Scanning of semantic actions is
3577 handled in scan-gram.l.
3578
3579 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
3580
3581 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
3582
3583 * src/location.h (struct): The file member is a uniqstr.
3584 (equal_boundaries): Use UNIQSTR_EQ for comparison.
3585
3586 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
3587
3588 Fix bug with non-%union parsers that have printers or destructors,
3589 which led to a Bison core dump. Reported by Peter Fales in
3590 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
3591
3592 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
3593 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
3594 not to our own type.
3595 * src/output.c (symbol_destructors_output, symbol_printers_output):
3596 Don't assume %union.
3597 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
3598 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
3599 UNION-FLAG. All callers changed.
3600 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
3601 Use type char, not unsigned int, when declaring an array of char;
3602 this lets us remove a cast.
3603 (Printers and Destructors): Add non-%union test cases.
3604
3605 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3606
3607 * doc/bison.texinfo: Minor editorial changes, mostly to the new
3608 GLR writeups. E.g., avoid frenchspacing and the future tense,
3609 change "lookahead" to "look-ahead", and change "wrt" to "with
3610 respect to".
3611
3612 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3613
3614 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
3615 New sections, split off from the GLR Parsers section. Put the new
3616 Simple GLR Parser near the start of the GLR section, for clarity.
3617 Rewrite connective text.
3618
3619 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
3620
3621 * doc/bison.texinfo (Simple GLR Parsers): New section.
3622
3623 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3624
3625 * NEWS, TODO, doc/bison.texinfo:
3626 Use "look-ahead" instead of "lookahead", to be consistent.
3627 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
3628 while we're fixing "look-ahead".
3629 * src/conflicts.c (shift_set): Renamed from shiftset.
3630 (look_ahead_set): Renamed from lookaheadset.
3631 * src/print.c: Likewise.

3650 * README: Update location of patched M4 distribution.
3651
3652 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
3653
3654 Don't assume the C++ compiler takes the same arguments as the C compiler
3655 (trivial change).
3656 * configure.ac (O0CXXFLAGS): New var.
3657 * tests/atlocal.in (CXXFLAGS): Use it.
3658
3659 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
3660
3661 Fix some "make check" problems with C++ reported by
3662 Albert Chin-A-Young for Tru64 C++ in this thread:
3663 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
3664
3665 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
3666 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
3667 Output to a .cc file for C++, not to a .c file.
3668 * tests/calc.at (AT_CHECK_CALC): Likewise.
3669 * tests/regression.at (AT_CHECK_DANCER): Likewise.
3670 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.

3676
3677 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
3678
3679 Spent a few hours checking out which prerequisite versions the
3680 current sources actually require. I went all the way back to
3681 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3682 a seemingly endless set of combinations of versions more recent
3683 than that. The bottom line is that the current sources require
3684 fairly recent versions of the build tools, and it'll be some work
3685 to change this.
3686 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3687 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3688 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3689 Add comments explaining why those particular versions are
3690 currently needed.
3691
3692 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
3693 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
3694 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
3695
3696 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
3697 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
3698
3699 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3700
3701 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
3702 0.11.5. Suggested by Bruno Haible.
3703 * bootstrap: Remove gettext version checking.
3704
3705 * doc/bison.texinfo (Decl Summary): Also mention that %union
3706 can depend on prerequisite types. Problem reported by Tim
3707 Van Holder.
3708
3709 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3710
3711 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
3712 * README-alpha: Don't tell people not to package this.
3713
3714 * bootstrap: Don't assume $(...) works; use `...` instead.
3715 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
3716 gettext better.
3717
3718 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
3719 put into the -d output file, and mention what to do if YYSTYPE is
3720 defined as a macro.
3721
3722 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3723
3724 Undo change made earlier today: it caused autopoint to not bring
3725 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
3726 autopoint's.
3727
3728 * bootstrap: Check that gettext version matches what's in
3729 configure.ac. Warn users to ignore robots.txt ERROR 404.
3730 * bootstrap: Undo today's earlier change (logged below).
3731 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
3732
3733 The gettext version checking is causing more trouble than it's
3734 curing; remove it. Problem reported by Paul Hilfinger.
3735
3736 * bootstrap: Issue a warning that one can expect a message
3737 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
3738 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
3739
3740 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
3741
3742 Ensure that the C++ compiler used for testing actually works on a
3743 simple test program; if not, skip the C++-related tests. Problem
3744 reported by Vin Shelton in:
3745 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
3746
3747 * m4/cxx.m4: New file.
3748 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
3749 * tests/atlocal.in (BISON_CXX_WORKS): Add.
3750 * tests/local.at (AT_COMPILE_CXX): Use it.
3751
3752 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
3753
3754 * data/glr.c (yylloc): Output this macro even if locations are not
3755 being generated, as the GLR parser needs it even in that case.
3756 Problem reported by Troy A. Johnson
3757 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
3758
3759 * configure.ac (AC_INIT): Update to 1.875e.
3760
3761 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
3762
3763 * NEWS: Version 1.875d.
3764 * configure.ac (AC_INIT): Likewise.
3765 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
3766
3767 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
3768 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
3769 lalr1.cc runs afoul of the first, and the last two are no longer
3770 supported by GCC 3.4.0.
3771 * README: Mention GNU m4 1.4 or later; mention m4 patches.
3772 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
3773
3774 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
3775
3776 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
3777 unsigned int, for compatibility with latest gnulib hash module.
3778 * src/state.c (state_hash, state_hasher): Likewise.
3779 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
3780 * src/uniqstr.c (hash_uniqstr): Likewise.
3781
3782 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3783
3784 * NEWS: Unescaped newlines are no longer allowed in char & strings.
3785
3786 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
3787 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
3788 character and string literals.
3789 (unexpected_end): New function.
3790 (unexpected_eof): Use it.
3791 (unexpected_newline): New function.
3792 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
3793 actions.
3794
3795 * NEWS: Document %expect-rr.
3796
3797 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
3798 Fix typo by replacing $1 with $option.
3799 Remove more 'intl'-related files.
3800 Don't DEFUN AM_INTL_SUBDIR twice.
3801
3802 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
3803 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
3804 strtoul.c.
3805 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
3806 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
3807 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
3808 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
3809 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
3810 * src/.cvsignore: Add *.output.
3811
3812 * src/parse-gram.y: Put copyright notice inside %{ %} so it
3813 gets copied to the output file.
3814
3815 2004-04-28 Paul Eggert <eggert@twinsun.com>
3816
3817 Get files from the gnulib and po repositories, instead of relying
3818 on them being in our CVS. Upgrade to latest versions of gnulib
3819 and Automake.
3820
3821 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
3822 * bootstrap: Bootstrap from gnulib and po repositories.
3823 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
3824 * README-cvs: Document these changes. Remove version numbers from
3825 mentions of build tools, since they change so often. Mention Flex.
3826
3827 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
3828 (gl_USE_SYSTEM_EXTENSIONS): Add.
3829 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
3830 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
3831 does this for us.
3832 (AC_ISC_POSIX): Remove; we no longer support this
3833 ancient OS, as it gets in the way of latest Autoconf & gnulib.
3834 (AC_HEADER_STDC): Remove: we now assume C89 or better.
3835 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
3836 Do not check for C89 headers, except for locale.h which is used
3837 by the Yacc library and must port to K&R hosts.
3838 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
3839 Do not check for C89 functions, except for setlocale which is
3840 used by the Yacc library.

3846 AM_GNU_GETTEXT): Remove; now done by:
3847 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
3848 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
3849 for us.
3850
3851 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
3852 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
3853 Define to empty, as gnulib.mk will do the rest for us.

3889 by bootstrap or automake.
3890
3891 * po/ChangeLog: Remove: all but one entry was a duplicate
3892 of this file, and I moved that 2000-11-02 entry here.

3914 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
3915 support it. (The latest stable gzip doesn't.)
3916
3917 2004-04-27 Paul Eggert <eggert@twinsun.com>
3918
3919 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
3920 case, as stos_ is now used by destructors due to the 2004-02-09
3921 change.
3922
3923 Remove more K&R C support.
3924 * lib/libiberty.y (PARAMS): Remove. All uses removed.

3941 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
3942 with latest obstack.h.
3943 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
3944 to procedure types, as obstack.h now does that for us.
3945 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
3946
3947 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
3948 so that this include file can stand alone.
3949 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
3950 does this now. Include subpipe.h first after config.h, to
3951 test whether it can stand alone.
3952
3953 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
3954 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
3955 unused declaration.
3956
3957 * tests/synclines.at (%union synch line): Put a dummy member in
3958 the union, because empty unions aren't allowed in C. Caught

3961 2004-04-13 Jim Meyering <jim@meyering.net>
3962

3966 2004-03-30 Paul Eggert <eggert@twinsun.com>
3967
3968 * src/getargs.c (version): Update copyright year to 2004.
3969
3970 * data/c.m4 (b4_int_type): Use 'short int' rather than
3971 'short', and similarly for 'long', 'unsigned', etc.

4026
4027 * doc/bison.texinfo: Add documentation for %expect-rr.
4028
4029 2004-03-08 Paul Eggert <eggert@gnu.org>
4030
4031 Add support for hex token numbers. Suggested by Odd Arild Olsen in
4032 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
4033
4034 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
4035 in lalr1.cc.
4036 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
4037 * src/scan-gram.l (scan_integer): New function.
4038 ({int}): Use it.
4039 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
4040 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
4041 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
4042 Say "long int", not "long", for uniformity with GNU style.
4043
4044 2004-02-25 Paul Eggert <eggert@twinsun.com>
4045
4046 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
4047 compilers. This fixes a problem with Intel's C++ compiler being
4048 chatty, reported by Guido Trentalancia in
4049 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
4050
4051 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
4052
4053 Support %destructor and merge error locations in lalr1.cc.

4060 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
4061 token which are discarded.
4062 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
4063 error_start_ when erroneous token are discarded.
4064 (Parser::parse) <yyerrlab1>: Compute the location of the error
4065 token so that it covers all the discarded tokens.
4066 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
4067 it can be called with `%skeleton "lalr1.cc"', and do that.
4068
4069 2004-02-02 Paul Eggert <eggert@twinsun.com>
4070
4071 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
4072 $(top_srcdir)/lib and ../lib. This fixes a bug reported
4073 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
4074 There's no need to mention top_builddir since Automake does that
4075 for us.
4076 (INCLUDES): Remove, as Automake says it's obsolescent.
4077 Contents migrated into AM_CPPFLAGS as described above.
4078 * lib/Makefile.am (INCLUDES): Remove; obsolescent.

4083 (yyreportSyntaxError): Handle case where lookahead token is
4084 YYEMPTY.
4085
4086 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4087
4088 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
4089 resulting parsers are compilable with C++.
4090
4091 2003-12-23 Paul Eggert <eggert@twinsun.com>
4092
4093 * config/depcomp, config/install-sh: Sync with Automake 1.8.
4094 * src/output.c (output_skeleton): Rename local var.
4095 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
4096 Bison tokens, as this runs afoul of the 2003-10-07 change that
4097 disallowed NUL bytes in character constants or string literals.
4098
4099 * tests/local.at: Require Autoconf 2.59's Autotest.
4100 * tests/testsuite.at: Don't include local.at, since we now assume
4101 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
4102 including it.
4103 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
4104 multiple inclusion warnings.
4105
4106 2003-12-02 Akim Demaille <akim@epita.fr>
4107
4108 * doc/bison.texinfo (How Can I Reset the Parser): More about start
4109 conditions.

4115
4116 2003-10-07 Paul Eggert <eggert@twinsun.com>
4117
4118 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
4119 if testsuite doesn't exist.
4120
4121 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
4122 literals, unfortunately.
4123 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
4124 Complain about NUL bytes in character constants or string literals.
4125
4126 2003-10-05 Paul Eggert <eggert@twinsun.com>
4127
4128 * NEWS: Don't document %no-default-prec, as it's still
4129 too experimental.
4130 * doc/bison.texinfo: Document %no-default-prec only if
4131 the defaultprec flag is set. Normally it's not.
4132
4133 2003-10-04 Paul Eggert <eggert@twinsun.com>
4134
4135 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
4136 non-modifiable lvalue, instead of a modifiable one.
4137 * doc/bison.texinfo (Actions): Document that $$ can
4138 be assigned to. Do not claim that $$ and $N are
4139 array element references: user code should not rely on this.
4140
4141 2003-10-01 Paul Eggert <eggert@twinsun.com>
4142
4143 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
4144 (grammar_declaration): Use it.
4145 * src/scan-gram.l: New token %no-default-prec.
4146 * tests/conflicts.at: Revamp tests to use %no-default-prec.
4147 * NEWS, doc/bison.texinfo: Document the above.
4148
4149 2003-10-01 Akim Demaille <akim@epita.fr>
4150
4151 VCG no longer supports long_straight_phase.
4152
4153 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
4154 * src/print_graph.c (print_graph): Adjust.
4155
4156 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
4157 and Paul Eggert <eggert@twinsun.com>
4158
4159 * doc/bison.texinfo (Decl Summary, Contextual Precedence,

4168 %default-prec with %prec, %default-prec 1): New tests.
4169
4170 2003-09-30 Paul Eggert <eggert@twinsun.com>
4171
4172 * tests/testsuite.at: Include local.at, not input.at, fixing
4173 a typo in the 2003-08-25 patch.
4174
4175 2003-08-27 Akim Demaille <akim@epita.fr>
4176
4177 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
4178 GCC warnings.
4179
4180 2003-08-26 Akim Demaille <akim@epita.fr>
4181
4182 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
4183 "<\#" to avoid magic from Gnus when posting parts of this script.
4184
4185 2003-08-26 Akim Demaille <akim@epita.fr>
4186
4187 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
4188 (Parser::parse): here.
4189 Adjust: nerrs and errstatus is now replaced by...
4190 (Parser::nerrs_, Parser::errstatus_): New.
4191

4193
4194 * config/announce-gen, Makefile.cfg: New.
4195 * Makefile.am: Adjust.

4198
4199 2003-08-25 Akim Demaille <akim@epita.fr>
4200
4201 When reducing initial empty rules, Bison parser read an initial
4202 location that is not defined. This results in garbage, and that
4203 affects Bison's own parser. Therefore we need (i) to extend Bison
4204 to support a means to initialize this location, and (ii) to use
4205 this CVS Bison to fix CVS Bison's parser.
4206
4207 * src/reader.h, reader.c (epilogue_augment): Remove, replace
4208 with...
4209 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
4210 * src/parse-gram.y: Adjust.
4211 (%initial-action): New.
4212 (%error-verbose): Since we require CVS Bison, there is no reason
4213 not to use it.
4214 * src/scan-gram.l: Adjust.
4215 * src/Makefile.am (YACC): New, to make sure we use our own parser.
4216 * data/yacc.c (yyparse): Use b4_initial_action.
4217
4218 2003-08-25 Akim Demaille <akim@epita.fr>
4219
4220 * doc/bison.texinfo: Don't promote stdout for error messages.
4221
4222 2003-08-25 Akim Demaille <akim@epita.fr>
4223
4224 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
4225 From Alexandre Duret-Lutz.
4226
4227 2003-08-25 Akim Demaille <akim@epita.fr>
4228
4229 Version 1.875c.
4230
4231 2003-08-25 Akim Demaille <akim@epita.fr>
4232
4233 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
4234 Use them.
4235
4236 2003-08-25 Akim Demaille <akim@epita.fr>
4237
4238 * data/lalr1.cc (Parser::reduce_print_): New.
4239 Use it.
4240
4241 2003-08-25 Akim Demaille <akim@epita.fr>
4242
4243 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
4244 error recovery loops. This patch is based on
4245 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
4246 Also, augment the similarity between lalr1.cc and yacc.c.
4247 Note: the locations of error recovery rules are not correct yet.
4248
4249 * data/lalr1.cc: Comment changes to augment the similarity between
4250 lalr1.cc and yacc.c.
4251 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
4252 (yyerrlab1): Remove, but where it used to be (now the bottom part of
4253 yyerrlab), when hitting EOF, pop the whole stack here instead of
4254 merely falling thru the default error handling mechanism.
4255 (yyerrorlab): New label, with the old contents of YYERROR,
4256 plus the following change: pop the stack of rhs corresponding
4257 to the production that invoked YYERROR. That is how Yacc
4258 behaves (required by POSIX).
4259 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
4260 fail.
4261
4262 2003-08-25 Akim Demaille <akim@epita.fr>
4263
4264 Tune local.at so that people can "autom4te -l autotest calc.at -o
4265 calc" for instance, to extract a sub test suite.
4266
4267 * tests/testsuite.at: Move the initialization, Autotest version
4268 requirement, and AT_TESTED invocation into...
4269 * tests/local.at: here.
4270 * tests/testsuite.at: Include it for compatibility with Autoconf
4271 2.57.
4272 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
4273 be ignore.
4274
4275 2003-08-04 Paul Eggert <eggert@twinsun.com>
4276
4277 Rework code slightly to avoid gcc -Wtraditional warnings.
4278 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
4279 The returned value is now stored in *YY0. All callers changed.
4280 * src/output.c (merge_output): Adjust to the above change.
4281
4282 2003-07-26 Paul Eggert <eggert@twinsun.com>
4283
4284 * data/glr.c (YYASSERT): New macro.
4285 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
4286 yyresolveStates, yyprocessOneStack):
4287 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
4288 Derived from a suggestion by Frank Heckenbach.
4289
4290 2003-07-25 Paul Eggert <eggert@twinsun.com>
4291
4292 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
4293 for portability to K&R C (after ansi2knr, presumably). See
4294 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
4295 by Frank Heckenbach, though I have omitted the structure-initialization
4296 part of his glr-knr.diff patch since I recall that the Portable
4297 C Compiler didn't require that change.
4298
4299 Let the user specify how to allocate and free memory.
4300 Derived from a suggestion by Frank Heckenbach in
4301 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
4302 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
4303 All uses of free, malloc, realloc changed to use these macros,
4304 and unnecessary casts removed.
4305 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
4306
4307 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
4308
4309 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
4310 use s.empty() rather than s == "" to test for empty string; see
4311 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
4312 (trivial change)
4313
4314 2003-06-25 Akim Demaille <akim@epita.fr>
4315
4316 * config/depcomp, config/install-sh: Update from masters.
4317
4318 2003-06-20 Paul Eggert <eggert@twinsun.com>
4319
4320 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
4321 and return properly parenthesized result.
4322 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
4323 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
4324 Remove unnecessary parentheses from uses.
4325 * doc/bison.texinfo (Location Default Action): Describe the
4326 conventions for parentheses.
4327
4328 2003-06-19 Paul Eggert <eggert@twinsun.com>
4329
4330 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
4331 yyreportTree): Do not assume that size_t is the same width as int,
4332 when printing sizes. Print sizes using an unsigned format.
4333 Problem reported by Frank Heckenbach in
4334 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
4335
4336 Port to Forte Developer 7 C compiler.
4337 * data/glr.c (struct YYLTYPE): If locations are not being used,
4338 declare a single dummy member, as empty structs do not conform
4339 to the C standard.
4340 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
4341 the Forte Developer 7 C compiler complains that end-of-loop
4342 code is not reached.
4343
4344 2003-06-17 Paul Eggert <eggert@twinsun.com>
4345
4346 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
4347 avoid warnings from picky compilers about redefinition of PARAMS.
4348
4349 2003-06-17 Paul Eggert <eggert@twinsun.com>
4350
4351 Version 1.875b.
4352
4353 * NEWS: Document 1.875b.
4354
4355 * lib/bbitset.h: Do not include config.h; that's the includer's job.
4356 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
4357 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
4358 Don't use 'index' in comments, as it's a builtin fn on some hosts.
4359 * lib/bitset_stats.c: Include gettext.h unconditionally, as
4360 per recent gettext manual's suggestion.
4361 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
4362 Use prototypes, not old-style definitions.
4363 * lib/lbitset.c (lbitset_unused_clear): Likewise.
4364 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
4365 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
4366 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
4367 vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,
4368 vbitset_xor, vbitset_xor_cmp, vbitset_and_or, vbitset_and_or_cmp,
4369 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
4370 vbitset_or_and_cmp, vbitset_copy): Likewise.
4371
4372 * lib/libiberty.h: Do not include config.h; that's the includer's job.
4373 Do not include <stdlib.h>.
4374 (PARAMS): Define unconditionally for C89.
4375 (ATTRIBUTE_NORETURN): Remove.
4376 (ATTRIBUTE_UNUSED): Define unconditionally.
4377
4378 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
4379 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
4380 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
4381 * lib/vbitset.c, lib/vbitset.h: New files.
4382 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
4383 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
4384 from libbitset.
4385
4386 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
4387 `How Can I Reset @code{yyparse}', since texinfo does not allow
4388 arbitrary @ in node names.
4389
4390 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
4391 shouldn't be needed according to the gettext 0.12.1 documentation
4392 but which seem to be needed anyway: codeset.m4 glibc21.m4
4393 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
4394 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
4395 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
4396
4397 * lib/.cvsignore: Add stdbool.h.
4398 * m4/.cvsignore: Add nls.m4, po.m4.
4399
4400 Upgrade to CVS gnulib.
4401 * stdbool_.h: File renamed from stdbool.h.in.
4402 * configure.ac (AM_STDBOOL_H): Invoke this instead of
4403 AC_HEADER_STDBOOL.
4404 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
4405 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
4406 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
4407 (MOSTLYCLEANFILES): New var.
4408 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
4409 (stdbool.h): New rule.
4410 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
4411 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
4412 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
4413 m4/quote.m4: Upgrade to today's gnulib.
4414
4415 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
4416 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
4417 the tests right now.
4418 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
4419 yyerror are declared before use; C99 requires this.
4420
4421 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4422
4423 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
4424 first.
4425 (yyrecoverSyntaxError): Correct the logic for setting and testing
4426 yyerrState.
4427 Correct comment on handling EOF.
4428 Allow states with only a default reduction, rather than failing
4429 (I can't quite reconstruct why these were not allowed before).
4430
4431 Fixes to avoid problem that $-N rules in GLR parsers can cause
4432 buffer overruns, corrupting state.
4433
4434 * src/output.c (prepare_rules): Output max_left_semantic_context
4435 definition.
4436 * src/reader.h (max_left_semantic_context): New variable declaration.
4437 * src/scan-gram.l (max_left_semantic_context): Define.
4438 (handle_action_dollar): Update max_left_semantic_context.
4439 * data/glr.c (YYMAXLEFT): New definition.
4440 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
4441 (yyresolveAction): Ditto.
4442
4443 Fixes to problems with location handling in GLR parsers reported by
4444 Frank Heckenbach (2003/06/05).
4445
4446 * data/glr.c (YYLTYPE): Make trivial if locations not used.
4447 (YYRHSLOC): Add parentheses, and define only if locations used.
4448 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
4449 locations not used.
4450 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
4451 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
4452
4453 * tests/cxx-type.at: Exercise location information; update tests
4454 to differentiate output with and without locations.
4455 Remove forward declarations of yylex and yyerror---caused errors
4456 because default YYLTYPE not yet defined.
4457 Change semantic actions to compute strings, rather than printing
4458 them directly (to test proper passing of semantics values). Change
4459 output to prefix notation and update test data and expected results.
4460 (yylex): Track locations.
4461 (stmtMerge): Return value rather than printing, and include arguments
4462 in value.
4463
4464 2003-06-03 Paul Eggert <eggert@twinsun.com>
4465
4466 Avoid warnings generated by GCC 2.95.4 when Bison is
4467 configured with --enable-gcc-warnings.
4468 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
4469 yy::]b4_parser_class_name[::translate_,
4470 yy::Stack::operator[] (unsigned),
4471 yy::Stack::operator[] (unsigned) const,
4472 yy::Slice::operator[] (unsigned),
4473 yy::Slice::operator[] (unsigned) const):
4474 Rename local vars to avoid warnings.
4475 * tests/glr-regression.at (Improper handling of embedded actions
4476 and $-N in GLR parsers): Remove unused local variable from yylex.
4477 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
4478 (void) as arg when not pure, since we now assume C89 when building
4479 Bison. Pacify GCC by using parameter.
4480
4481 2003-06-02 Paul Eggert <eggert@twinsun.com>
4482
4483 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
4484 yy::Location::lines, yy::Location::columns): Rename arguments
4485 to avoid shadowing; this removes a warning generated by GCC 3.3.
4486
4487 2003-06-01 Paul Eggert <eggert@twinsun.com>
4488
4489 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
4490 to g++, as GCC 3.3 complains if you do it.
4491 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
4492 everything that WARNING_CFLAGS has, except omit warnings
4493 not suitable for C++.
4494 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
4495 * tests/atlocal.in (CXXFLAGS): New var.
4496 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
4497
4498 Fix a GLR parser bug I reported in February; see
4499 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
4500 The problem was that GLR parsers did not conform to the C standard,
4501 because actions like { $1 = $2 + $3; } expanded to expressions
4502 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4503 to a local variable. The C standard says that expressions
4504 like (var = f ()) + (var = f ()) have undefined behavior.
4505 Another problem was that GCC sometimes issues warnings that
4506 yyfill and its parameters are unused.
4507
4508 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4509 as possibly unused.
4510 (yyfill): New function.
4511 (YYFILL): Use it.
4512 (yyuserAction): Change type of yynormal to bool, so that it matches
4513 the new yyfill signature. Mark it as possibly unused.
4514
4515
4516 Follow up on a bug I reported in February, where a Bison-generated
4517 parser can loop. Provide a test case and a fix for yacc.c. I
4518 don't have a fix for lalr1.cc or for glr.c, unfortunately.
4519 The original bug report is in:
4520 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
4521
4522 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4523 macro's size was becoming unwieldy.
4524 (yyerrlab): Do not discard an empty lookahead symbol, as this
4525 might destroy garbage.
4526 (yyerrorlab): New label, with the old contents of YYERROR,
4527 plus the following change: pop the stack of rhs corresponding
4528 to the production that invoked YYERROR. That is how Yacc
4529 behaves, and POSIX requires this behavior.
4530 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4531 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4532 Define 'alarm' to do nothing if unistd.h is not available.
4533 Add a new rule "exp: '-' error;" to test the above change to
4534 data/yacc.c. Use 'alarm' to abort any test taking longer than
4535 10 seconds, as it's probably looping.
4536 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4537 Also, the new yacc.c generates two fewer diagnostics for an
4538 existing test.
4539
4540 2003-05-24 Paul Eggert <eggert@twinsun.com>
4541
4542 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
4543 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
4544 This fixes a problem reported by John Bowman when the Compaq/HP
4545 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
4546 -ansi -Wall -gall).
4547 * data/yacc.c (union yyalloc): Likewise.
4548 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
4549
4550 Switch from 'int' to 'bool' where that makes sense.
4551

4555 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
4556 Return or accept bool, not int. All callers changed.

4566 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
4567 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
4568 bitset_stats_or_and_cmp): Likewise.

4571 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
4572 ebitset_xor_cmp): Likewise.
4573 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
4574 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
4575 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
4576 lbitset_xor_cmp): Likewise.
4577 * lib/bbitset.h: Include <stdbool.h>.
4578 (struct bitset_vtable): The following members now return bool, not
4579 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
4580 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
4581 or_and_cmp).
4582 * src/conflicts.c (count_rr_conflicts): Likewise.
4583 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
4584 All uses changed.
4585 * lib/ebitset.c (ebitset_obstack_init): Likewise.

4606 symbol_destructors_output, symbol_destructors_output): Use string,
4607 not boolean integer, to keep track of whether to output separator.
4608 * src/print_graph.c (print_core): Likewise.
4609 * src/state.c (state_rule_lookaheads_print): Likewise.
4610
4611 * config/install-sh: Sync from automake 1.7.5.
4612
4613 2003-05-14 Paul Eggert <eggert@twinsun.com>
4614
4615 * src/parse-gram.y (rules_or_grammar_declaration): Require a
4616 semicolon after a grammar declaration, in the interest of possible
4617 future changes to the Bison input language.
4618 Do not allow a stray semicolon at the start of the grammar.
4619 (rhses.1): Allow one or more semicolons after any rule, including
4620 just before "|" as required by POSIX.
4621 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
4622 grammar.
4623
4624 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4625
4626 %parse-param support for lalr1.cc.
4627
4628 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
4629 b4_cc_constructor_calls, b4_cc_constructor_call,
4630 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
4631 definitions.
4632 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
4633 parse-param arguments.
4634 (yy::b4_parser_class_name): Declare instance variables to
4635 hold parse-param arguments.
4636 * tests/calc.at: s/value/semantic_value/ because value clashes
4637 with a member of yy::b4_parser_class_name. Adjust C++ code
4638 to handle %parse-param. Enable %parse-param test in C++.
4639
4640 2003-05-12 Paul Eggert <eggert@twinsun.com>
4641
4642 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
4643 English a bit. Fix fclose typo. Change "const char" to "char
4644 const", and use ANSI C rather than K&R for "main". Suggest
4645 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
4646 and suggest yy_switch_to_buffer.
4647
4648 2003-05-05 Paul Eggert <eggert@twinsun.com>
4649
4650 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
4651 C89. This avoids a diagnostic on compilers that define __STDC__
4652 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
4653 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4654
4655 2003-05-03 Paul Eggert <eggert@twinsun.com>
4656
4657 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
4658 Do not overrun array bounds.
4659 This should fix a bug reported today by Olatunji Oluwabukunmi in
4660 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
4661
4662 2003-04-29 Akim Demaille <akim@epita.fr>
4663
4664 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
4665 * src/getargs.c, src/getargs.h: here, as bool, not int.
4666 (nondeterministic_parser): New.
4667 * src/parse-gram.y, src/scan-gram.l: Support
4668 %nondeterministic-parser.
4669 * src/output.c (prepare): Use nondeterministic_parser instead
4670 of glr_parser where appropriate.
4671 * src/tables.c (conflict_row, action_row, save_row)
4672 (token_actions, token_actions, pack_vector): Ditto.
4673
4674 2003-04-29 Akim Demaille <akim@epita.fr>
4675
4676 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
4677
4678 2003-04-29 Akim Demaille <akim@epita.fr>
4679
4680 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
4681 with %pure-parser and %locations to exercise the patch from Yakov
4682 Markovitch below.
4683
4684 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
4685
4686 * data/yacc.c: (b4_lex_param): Corrected for the case where
4687 %lex-param is provided and %pure-parser isn't.
4688
4689 2003-04-27 Paul Eggert <eggert@twinsun.com>
4690
4691 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
4692 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
4693 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
4694 if it is not defined.
4695 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
4696
4697 2003-04-26 Paul Eggert <eggert@twinsun.com>
4698
4699 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
4700 Declare to be of type suitable for the ninf value itself, not of
4701 type suitable for the corresponding table, since the latter might
4702 be unsigned but the ninf value might be negative. This fixes a
4703 bug reported by Alexandre Duret-Lutz in
4704 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
4705
4706 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
4707 invokes it. We shouldn't invoke it twice because it will attempt
4708 to put error.o in the archive twice. This fixes a glitch reported
4709 by Martin Mokrejs in
4710 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4711
4712 2003-04-21 Paul Eggert <eggert@twinsun.com>
4713
4714 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
4715 to gnulib.
4716
4717 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
4718
4719 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
4720 Fix obvious typo that results in uncompilable GLR parsers
4721 when both %pure-parser and %locations are used. (trivial change)
4722
4723 2003-04-17 Paul Eggert <eggert@twinsun.com>
4724
4725 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
4726 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
4727 Do not insert the expected token via unput, as this runs afoul
4728 of a POSIX-compatibility bug in flex 2.5.31.
4729 All uses changed to BEGIN the parent state,
4730 since we no longer insert the expected token via unput.
4731 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
4732 that is no longer emitted after the above change.
4733
4734 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
4735 the first one. This change is from Paul Hilfinger, and it fixes
4736 regression reported by Werner Lemberg in
4737 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
4738
4739 (resolve_sr_conflict): Don't invoke state_errs_set
4740 unless one or more tokens have been explicitly made errors.
4741 Otherwise, the above change causes Bison to abort.
4742
4743 * tests/existing.at (GNU pic Grammar): New test case, taken from
4744 Lemberg's email.
4745
4746 2003-03-31 Akim Demaille <akim@epita.fr>
4747
4748 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
4749
4750 2003-03-31 Akim Demaille <akim@epita.fr>
4751
4752 * src/output.c (prepare_symbols): Avoid trailing spaces in the
4753 output.
4754
4755 2003-03-31 Akim Demaille <akim@epita.fr>
4756
4757 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
4758 From Paul Hilfinger.
4759
4760 2003-03-29 Akim Demaille <akim@epita.fr>
4761
4762 * m4/error.m4: Do not put under dynamic conditions some code which
4763 expansion is under static control.
4764
4765 2003-03-29 Akim Demaille <akim@epita.fr>
4766
4767 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
4768
4769 2003-03-29 Akim Demaille <akim@epita.fr>
4770
4771 * doc/bison.texinfo (Strings are Destroyed): New.
4772
4773 2003-03-13 Paul Eggert <eggert@twinsun.com>
4774
4775 * .cvsignore: Add configure.lineno.
4776 * src/.cvsignore: Add yacc.
4777 * tests/.cvsignore: Add testsuite.log.
4778 * doc/fdl.texi: Sync with latest FSF version.
4779
4780 2003-03-12 Paul Eggert <eggert@twinsun.com>
4781
4782 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
4783 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
4784 cursor, instead of leaving it undefined. This fixes a bug
4785 reported by Tim Van Holder in
4786 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
4787 * tests/input.at (Torturing the Scanner): Test the scanner on
4788 an empty input file, which was Tim Van Holder's test case.
4789
4790 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
4791 <sys/resource.h> can be included, include sys/time.h and
4792 sys/times.h first, if available. This works around the SunOS
4793 4.1.4 porting bug reported by Bruce Becker in
4794 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
4795
4796 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
4797 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
4798 AC_HEADER_SYS_WAIT.
4799
4800 Merge changes from gnulib. This was prompted because the CVS
4801 snapshot didn't build on Solaris 7 due to strnlen problems.
4802
4803 These changes need to be merged back into gnulib:
4804 * lib/hash.c: Include <stdbool.h> unconditionally.
4805 * m4/onceonly.m4 (m4_quote): New macro.
4806 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
4807 Quote AC_FOREACH variable-expansions properly.
4808 The 2003-01-03 obstack.h change also needs merging.
4809 {end of changes requiring merging}
4810
4811 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
4812 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
4813 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
4814 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
4815 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
4816 New files, imported from gnulib.
4817 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
4818 above.
4819
4820 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
4821 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
4822 gnulib sources.
4823
4824 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
4825 Add.
4826 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
4827 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
4828 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
4829 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
4830 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
4831 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
4832 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
4833 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
4834 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
4835 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
4836 (jm_PREREQ_ARGMATCH): Remove.
4837 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
4838 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
4839
4840 * src/system.h: Include <stdbool.h> unconditionally.
4841
4842 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
4843 assuming at least C89 in the bitset code for some time now.
4844
4845 2003-03-03 Akim Demaille <akim@epita.fr>
4846
4847 * ro.po: New.
4848
4849 2003-03-02 Akim Demaille <akim@epita.fr>
4850
4851 * doc/bison.texinfo (Table of Symbols): Reactivate the
4852 documentation for %lex-param, and %parse-param.
4853
4854 2003-03-02 Akim Demaille <akim@epita.fr>
4855
4856 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
4857 generate verbose error messages.
4858 Use the number of tokens as an upper bound in yytname, as it
4859 cannot be a non terminal.
4860
4861 2003-03-02 Akim Demaille <akim@epita.fr>
4862
4863 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
4864 message.
4865
4866 2003-03-02 Akim Demaille <akim@epita.fr>
4867
4868 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
4869 Use them to exercise yycheck overrun.
4870 Based on Andrew Suffield's grammar.
4871
4872 2003-03-02 Akim Demaille <akim@epita.fr>
4873
4874 Create tests/local.at for Bison generic testing macros.
4875
4876 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
4877 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
4878 This new file.
4879 * tests/calc.at (AT_CHECK_CALC): Adjust.
4880 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
4881 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
4882 * tests/local.at: here.
4883 (AT_COMPILE_CXX): Tags the tests using it as c++.
4884 Ignore the test if CXX is not functional.
4885
4886 2003-03-01 Paul Eggert <eggert@twinsun.com>
4887
4888 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
4889 not loc->end, since loc->end might contain garbage and this leads
4890 to undefined behavior on some platforms.
4891 (id_loc, token_start): Use (IF_LINTed) initial values that do not
4892 depend on *loc, so that the reader doesn't give the the false
4893 impression that *loc is initialized.
4894 (<INITIAL>"%%"): Do not bother setting code_start, since its value
4895 does not survive the return.
4896
4897 2003-03-01 Akim Demaille <akim@epita.fr>
4898
4899 * src/scan-gram.l (code_start): Always initialize it when entering
4900 into yylex, as SC_EPILOGUE is activated *before* the corresponding
4901 yylex invocation. An alternative would be making it static, but
4902 then it starts with the second %%'s beginning, instead of its end.
4903
4904 2003-02-28 Paul Eggert <eggert@twinsun.com>
4905
4906 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
4907 around a UnixWare 7.1.1 porting bug reported by John Hughes in
4908 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
4909
4910 2003-02-26 Paul Eggert <eggert@twinsun.com>
4911
4912 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
4913 Remove Sequent/Pyramid discussion (nobody uses them any more).
4914 Merge VMS and MS-DOS discussion; these ports may well be dead
4915 but let's keep mentioning them for now. Put <> around email
4916 addresses. Add copyright notice.
4917
4918 2003-02-24 Paul Eggert <eggert@twinsun.com>
4919
4920 * data/glr.c (yy_reduce_print): yylineno -> yylno,
4921 to avoid collision with flex use of yylineno.
4922 Problem reported by Bruce Lilly in
4923 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
4924 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
4925 * data/yacc.c (yy_reduce_print): Likewise.
4926
4927 * config/depcomp: Sync with Automake 1.7.3.
4928
4929 2003-02-21 Akim Demaille <akim@epita.fr>
4930
4931 * data/lalr1.cc: Use temporary variables instead of casts to
4932 change integer types.
4933 Suggested by Paul Eggert.
4934
4935 2003-02-21 Akim Demaille <akim@epita.fr>
4936
4937 * doc/bison.texinfo: Use "location" consistently to refer to @n,
4938 to avoid confusions with lalr1.cc's notion of Position.
4939 Suggested by Paul Eggert.
4940
4941 2003-02-20 Akim Demaille <akim@epita.fr>
4942
4943 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
4944 before initial_columns.
4945 (location.hh): Use consistent variable names when defining the
4946 operator<<.
4947 Use "last" so that we subtract from Positions, not from unsigned.
4948
4949 2003-02-20 Akim Demaille <akim@epita.fr>
4950
4951 * data/lalr1.cc (position.hh): New subfile, including the extended
4952 and Doxygen'ed documentation of class Position.
4953 (location.hh): Use it.
4954 Document a` la Doxygen.
4955 With the help of Benoit Perrot.
4956
4957 2003-02-20 Akim Demaille <akim@epita.fr>
4958
4959 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
4960 AT_YACC_IF.
4961 Redefine AT_YYERROR_SEES_LOC_IF using it.
4962 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
4963 not defined.
4964 Don't use the location in yy::Parser::error_ and
4965 yy::Parser::print_ when not %locations.
4966 Activate more lalr1.cc tests.
4967
4968 2003-02-19 Akim Demaille <akim@epita.fr>
4969
4970 * data/lalr1.cc: When displaying a line number, be sure to make it
4971 an int.
4972
4973 2003-02-19 Akim Demaille <akim@epita.fr>
4974
4975 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
4976 Remove, useless.
4977 (YYABORT, YYACCEPT, YYERROR): New.
4978 * tests/calc.at: Renable the lalr1.cc test.
4979
4980 2003-02-19 Akim Demaille <akim@epita.fr>
4981
4982 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
4983 error recovery, mixing with/without pops and discarding of the
4984 lookahead.
4985 Exercise YYERROR.
4986 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
4987
4988 2003-02-17 Paul Eggert <eggert@twinsun.com>
4989
4990 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
4991 * tests/testsuite.at (AT_COMPILE): Use them.
4992 This fixes the testsuite problem reported by Robert Lentz in
4993 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
4994
4995 2003-02-12 Paul Eggert <eggert@twinsun.com>
4996
4997 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
4998 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
4999 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
5000 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
5001 Check for malloc failure, for consistency with yacc.c.
5002 (yytname_size): Remove, for consistency with yacc.c.
5003
5004 The bug still remains in data/lalr1.cc, as I didn't have time
5005 to fix it there.
5006
5007 2003-02-06 Akim Demaille <akim@epita.fr>
5008
5009 * configure.ac (GXX): Rename as...
5010 (CXX): this, to keep the original Autoconf semantics.
5011 Require 2.57.
5012 * data/lalr1.cc: Fix b4_copyright invocations.
5013 If YYDEBUG is not defined, don't depend upon name_ being defined.
5014 (location.hh): Include string and iostream.
5015 (Position::filename): New member.
5016 (Position::Position ()): New.
5017 (operator<< (Position)): New.
5018 (operator- (Position, int)): New.
5019 (Location::first, Location::last): Rename as...
5020 (Location::begin, Location::end): these, to mock the conventional
5021 iterator names.
5022 (operator<< (Location)): New.
5023 * tests/atlocal.in (CXX): New.
5024 * tests/testsuite.at (AT_COMPILE_CXX): New.
5025 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
5026 locations in a more synthetic way.
5027 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
5028 lalr1.cc is used.
5029 Adjust the C locations to match those from Emacs: first column is
5030 column 0.
5031 Change all the expected results.
5032 Conform to the GCS: simplify the locations when applicable.
5033 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
5034 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
5035 these CPP macros with the m4 macros new defined by...
5036 (AT_CHECK_PUSHDEFS): this, i.e.:
5037 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
5038 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
5039 New macros.
5040 (AT_CHECK_POPDEFS): Undefine them.
5041 (AT_CHECK_CALC_LALR1_CC): New.
5042 Use it for the first lalr1.cc test.
5043
5044 2003-02-04 Akim Demaille <akim@epita.fr>
5045
5046 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
5047 Location as is defined.
5048
5049 2003-02-04 Akim Demaille <akim@epita.fr>
5050
5051 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
5052 name_ being defined.
5053
5054 2003-02-03 Paul Eggert <eggert@twinsun.com>
5055
5056 * src/gram.h (start_symbol): Remove unused decl.
5057
5058 Use more-consistent naming conventions for local vars.
5059
5060 * src/derives.c (derives_compute): Change type of local var from
5061 int to rule_number.
5062 * src/gram.c (grammar_rules_partial_print): Likewise.
5063 * src/print.c (print_core): Likewise.
5064 * src/reduce.c (reduce_grammar_tables): Likewise.
5065
5066 * src/gram.c (grammar_dump): Change name of item_number *
5067 local var from r to rp.
5068 * src/nullable.c (nullable_compute): Likewise.
5069
5070 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
5071
5072 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
5073 for symbol or symbol_number var.
5074 * src/reader.c (grammar_start_symbol_set): Likewise.
5075 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
5076 Likewise.
5077 * src/state.c (transitions_to): Likewise.
5078 * src/state.h: Likewise.
5079 * src/tables.c (symbol_number_to_vector_number): Likewise.
5080
5081 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
5082 char * var.
5083
5084 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
5085 var.
5086
5087 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
5088 var.
5089
5090 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
5091 Use str, not s, for char * var. Use ch, not c, for character var.
5092 Use size for size var.
5093
5094 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
5095 char * var.
5096 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
5097 uniqstr var.
5098 * src/uniqstr.h: Likewise.
5099
5100 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
5101 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
5102 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
5103 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
5104 param to have same name as that of enum, so that we don't use
5105 "s" to stand for a non-state.
5106
5107 2003-02-02 Akim Demaille <akim@epita.fr>
5108
5109 * src/scan-skel.l: Scan more than one inert character per yylex
5110 invocation.
5111
5112 2003-02-01 Paul Eggert <eggert@twinsun.com>
5113
5114 Version 1.875a.
5115
5116 * po/LINGUAS: Add ms.
5117
5118 2003-01-30 Akim Demaille <akim@epita.fr>
5119
5120 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
5121
5122 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5123
5124 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
5125 of $1.
5126
5127 Changes in response to error report by S. Eken: GLR mode does not
5128 handle negative $ indices or $ indices in embedded rules correctly.
5129 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
5130
5131 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
5132 (b4_rhs_location): Ditto.
5133 (yyfill): New function to copy from stack tree into array
5134 incrementally.
5135 (yyuserAction): Modify to allow incremental move of semantic values
5136 to rhs array when in GLR mode.
5137 Define YYFILL to use in user-defined actions to fill semantic array
5138 as needed.
5139 Remove dummy use of yystack, as there is now a guaranteed use.
5140 (yydoAction): Modify to allow incremental move of semantic values
5141 to rhs array when in GLR mode.
5142 (yyresolveAction): Ditto.
5143 (yyglrShiftDefer): Update comment.
5144 (yyresolveStates): Use X == NULL for pointers, not !X.
5145 (yyglrReduce): Ditto.
5146 (yydoAction): Ditto
5147
5148 * tests/glr-regr1.at: Rename to ...
5149 * tests/glr-regression.at: Add new regression test for the problems
5150 described above (adapted from S. Eken).
5151 Update copyright notice.
5152 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
5153 * tests/Makefile.am: Ditto.
5154
5155 2003-01-28 Paul Eggert <eggert@twinsun.com>
5156
5157 * data/lalr1.cc: Do not use @output_header_name@ unless
5158 b4_defines_flag is set. This fixes two bugs reported by
5159 Tim Van Holder in
5160 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
5161 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
5162
5163 2003-01-21 Paul Eggert <eggert@twinsun.com>
5164
5165 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
5166 we don't need to worry about yyerrlab1 being reported as an
5167 "unused label" by non-GCC C compilers. The downside is that if
5168 locations are used then a couple of statements are duplicated each
5169 time YYERROR is invoked, but the upside is that the warnings
5170 should vanish.
5171 (yyerrlab1): Move code to YERROR.
5172 (yyerrlab2): Remove. Change uses back to yyerrlab1.
5173 This reverts some of the 2002-12-27 change.
5174
5175 2003-01-17 Paul Eggert <eggert@twinsun.com>
5176
5177 * src/output.c (symbol_printers_output): Fix typo that led
5178 to core dump. Problem reported by Antonio Rus in
5179 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
5180
5181 2003-01-13 Akim Demaille <akim@epita.fr>,
5182 Quoc Peyrot <chojin@lrde.epita.fr>,
5183 Robert Anisko <anisko_r@lrde.epita.fr>
5184
5185 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
5186 when the stacks contain one element, as the loop would otherwise
5187 free the last state, and then use the top state (the one we just
5188 popped). This means that the initial elements will not be freed
5189 explicitly, as is the case in yacc.c; it is not a problem, as
5190 these elements have fake values.
5191
5192 2003-01-11 Paul Eggert <eggert@twinsun.com>
5193
5194 * NEWS: %expect-violations are now just warnings, reverting
5195 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
5196 bootstrapping problem reported by Matthias Klose; see
5197 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
5198 * src/conflicts.c (conflicts_print): Likewise.
5199 * tests/conflicts.at (%expect not enough, %expect too much,
5200 %expect with reduce conflicts): Likewise.
5201 * doc/bison.texinfo (Expect Decl): Document this. Also mention
5202 that the warning is enabled if the number of conflicts changes
5203 (not necessarily increases).
5204
5205 * src/getargs.c (version): Update copyright year.
5206
5207 2003-01-09 Akim Demaille <akim@epita.fr>
5208
5209 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
5210
5211 2003-01-08 Paul Eggert <eggert@twinsun.com>
5212
5213 * Makefile.maint (WGETFLAGS):
5214 New macro, containing "-C off" to disable proxy caches.
5215 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
5216 (rel-check): Use $(WGET) instead of wget.
5217
5218 2003-01-06 Paul Eggert <eggert@twinsun.com>
5219
5220 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
5221 the GLR paper of Scott, Johnstone and Hussain.
5222
5223 2003-01-04 Paul Eggert <eggert@twinsun.com>
5224
5225 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
5226 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
5227 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
5228 (EXTRA_LIBRARIES): New var, for liby.a.
5229 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
5230 (EXTRA_SCRIPTS): New var, for yacc.
5231
5232 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
5233 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
5234 Problem reported by Nelson H. F. Beebe.
5235
5236 2003-01-03 Paul Eggert <eggert@twinsun.com>
5237
5238 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
5239 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
5240 when compiling Bison 1.875's `bitset bset = obstack_alloc
5241 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
5242
5243 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
5244 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
5245 grow to a huge size with typical invocation.
5246
5247 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
5248 Use the pattern recommended by Autoconf 2.57, except also protect
5249 against double-definition.
5250 * src/system.h: Likewise.
5251 Portability issues reported by Nelson H. F. Beebe.
5252
5253 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
5254 All uses changed. Provide a definition in both C and C++.
5255 (yytrue, yyfalse): Define even if defined (__cplusplus).
5256
5257 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
5258 Reported by Nelson H. F. Beebe.
5259
5260 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
5261
5262 2003-01-02 Paul Eggert <eggert@twinsun.com>
5263
5264 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
5265 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
5266 Bug reported by Nelson H. F. Beebe.
5267
5268 2003-01-01 Paul Eggert <eggert@twinsun.com>
5269
5270 * Version 1.875.
5271
5272 2002-12-30 Paul Eggert <eggert@twinsun.com>
5273
5274 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
5275 Moved here from...
5276 (<INITIAL>","): Here. This causes stray "," to be treated
5277 more uniformly.
5278
5279 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
5280 last brace in braced code when not in Yacc mode, for compatibility
5281 with Bison 1.35. This resurrects the 2001-12-15 patch to
5282 src/reader.c.
5283
5284 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
5285 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
5286
5287 2002-12-28 Paul Eggert <eggert@twinsun.com>
5288
5289 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
5290 that of SYM's type. This fixes Debian bug 168069, reported by
5291 Thomas Olsson.
5292
5293 2002-12-28 Paul Eggert <eggert@twinsun.com>
5294
5295 Version 1.75f.
5296
5297 Switch back to the Yacc style of conflict reports, undoing some
5298 of the 2002-07-30 change.
5299 * doc/bison.texinfo (Understanding): Use Yacc style for
5300 conflict reports. Also, use new way of locating rules.
5301 * src/conflicts.c (conflict_report):
5302 Renamed from conflict_report_yacc, removing the old
5303 'conflict_report'. Translate the entire conflict report at once,
5304 so that we don't assume that "," has the same interpretation in
5305 all languages.
5306 (conflicts_output): Use Yacc-style conflict report for each state,
5307 instead of our more-complicated style.
5308 (conflicts_print): Use Yacc-style conflict report, except print
5309 the input file name when not emulating Yacc.
5310 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
5311 Conflicted Reduction, %expect not enough, %expect too much,
5312 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
5313 * tests/existing.at (GNU Cim Grammar): Likewise.
5314 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
5315
5316 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
5317 fatal): Don't invoke fflush; it's not needed and it might even be
5318 harmful for stdout, as stdout might not be open.
5319 * src/reduce.c (reduce_print): Likewise.
5320
5321 2002-12-27 Paul Eggert <eggert@twinsun.com>
5322
5323 Fix a bug where error locations were not being recorded correctly.
5324 This problem was originally reported by Paul Hilfinger in
5325 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
5326
5327 * data/yacc.c (yyparse): New local var yylerrsp, to record the
5328 top of the location stack's error locations.
5329 (yyerrlab): Set it. When discarding a token, push its location
5330 onto yylerrsp so that we don't lose track of the error's end.
5331 (yyerrlab1): Now is only the target of YYERROR, so that we can
5332 properly record the location of the action that failed. For GCC
5333 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
5334 GCC warning about yyerrlab1 being unused if YYERROR is unused.
5335 (yyerrlab2): New label, which yyerrlab now falls through to.
5336 Compute the error's location by applying YYLLOC_DEFAULT to
5337 the locations of all the symbols that went into the error.
5338 * doc/bison.texinfo (Location Default Action): Mention that
5339 YYLLOC_DEFAULT is also invoked for syntax errors.
5340 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
5341 Error locations include the locations of all the tokens that were
5342 discarded, not just the last token.
5343
5344 2002-12-26 Paul Eggert <eggert@twinsun.com>
5345
5346 * src/files.c: Include quote.h.
5347 (compute_output_file_names): Warn if we detect conflicting
5348 outputs to the same file. This should catch the misunderstanding
5349 exemplified by Debian Bug 165349, reported by Bruce Stephens..
5350
5351 * src/conflicts.c (conflicts_print): If the user specifies
5352 "%expect N", report an error if there are any reduce/reduce
5353 conflicts. This is what the manual says should happen.
5354 This fixes Debian bug 130890, reported by Anthony DeRobertis.
5355 * tests/conflicts.at (%expect with reduce conflicts): New test.
5356
5357 Don't use m4_include on relative file names, as it doesn't work as
5358 desired if there happens to be a file with that name under ".".
5359
5360 * m4sugar/version.m4: Remove; it was included but it wasn't used.
5361 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
5362 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
5363 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
5364 * src/output.c (output_skeleton): Use full path names when
5365 specifying a file to include; don't rely on include path, as
5366 it's unreliable when the working file contains a file with
5367 that name.
5368
5369 2002-12-25 Paul Eggert <eggert@twinsun.com>
5370
5371 Remove obsolete references to bison.simple and bison.hairy.
5372 Problem mentioned by Aubin Mahe in
5373 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
5374 * data/glr.c: Comment fix.
5375 * doc/bison.1: Remove references. Also, mention "yacc".
5376
5377 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
5378 with -g option.
5379
5380 * src/parse-gram.y (declaration): Use enum "report_states" rather
5381 than its numeric value 1.
5382
5383 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
5384 opening a new one. This fixes Debian bug 165349, reported by
5385 Bruce Stephens.
5386
5387 2002-12-24 Paul Eggert <eggert@twinsun.com>
5388
5389 Version 1.75e.
5390
5391 * Makefile.maint (cvs-update): Don't assume that the shell
5392 supports $(...), as Solaris sh doesn't.
5393
5394 * src/parse-gram.y (lloc_default): Remove test for empty
5395 nonterminals at the end, since it didn't change the result.
5396
5397 2002-12-24 Paul Eggert <eggert@twinsun.com>
5398
5399 If the user does not define YYSTYPE as a macro, Bison now declares it
5400 using typedef instead of defining it as a macro. POSIX requires this.
5401 For consistency, YYLTYPE is also declared instead of defined.
5402
5403 %union directives can now have a tag before the `{', e.g., the
5404 directive `%union foo {...}' now generates the C code
5405 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5406 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5407 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5408 instead of `yyltype'.
5409
5410 `yystype' and `yyltype' are now obsolescent macros instead of being
5411 typedefs or tags; they are no longer documented and will be
5412 withdrawn in a future release.
5413
5414 * data/glr.c (b4_location_type): Remove.
5415 (YYSTYPE): Renamed from yystype.
5416 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
5417 (struct YYLTYPE): Renamed from struct yyltype.
5418 (YYLTYPE): Renamed from yyltype.
5419 (yyltype, yystype): New (and obsolescent) macros,
5420 for backward compatibility.
5421 * data/yacc.c: Likewise.
5422
5423 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
5424 does not specify a union tag. This is for compatibility with
5425 Solaris 9 yacc.
5426
5427 * src/parse-gram.y (add_param): 2nd arg is now char * not char
5428 const *, since it is now modified by stripping surrounding { }.
5429 (current_braced_code): Remove.
5430 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
5431 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
5432 trailing " {...}". Now of type <chars>.
5433 (grammar_declaration): Adjust to bundled tokens.
5434 (code_content): Remove; stripping is now done by add_param.
5435 (print_token_value): Print contents of bundled tokens.
5436 (token_name): New function.
5437
5438 * src/reader.h (braced_code, current_braced_code): Remove.
5439 (token_name): New decl.
5440
5441 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
5442 token_type, not braced_code code_kind. All uses changed.
5443 (SC_PRE_CODE): New state, for scanning after a keyword that
5444 has (or usually has) an immediately-following braced code.
5445 (token_type): New local var, to keep track of which token type
5446 to return when scanning braced code.
5447 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
5448 <INITIAL>"%parse-param", <INITIAL>"%printer",
5449 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
5450 instead of returning a token type immediately.
5451 (<INITIAL>"{"): Set token type.
5452 (<SC_BRACED_CODE>"}"): Use it.
5453 (handle_action_dollar, handle_action_at): Now returns bool
5454 indicating success. Fail if ! current_rule; this prevents a core dump.
5455 (handle_symbol_code_dollar, handle_symbol_code_at):
5456 Remove; merge body into caller.
5457 (handle_dollar, handle_at): Complain in invalid contexts.
5458
5459 * NEWS, doc/bison.texinfo: Document the above.
5460 * NEWS: Fix years and program names in copyright notice.

5463
5464 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
5465 Reporting, Table of Symbols): Omit mentions of %lex-param and
5466 %parse-param from the documentation for now.
5467
5468 2002-12-15 Paul Eggert <eggert@twinsun.com>
5469
5470 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
5471 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
5472 lookahead symbol, and which sets yychar in parser actions) and it
5473 disagreed with the Bison documentation. Bug
5474 reported by Andrew Walrond.
5475
5476 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
5477 as the caller now does that.
5478 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
5479 (YYEMPTY): Parenthesize right hand side, since others use it.
5480 (yyparse): Don't assume that our generated code is the only code
5481 that sets yychar.
5482
5483 2002-12-13 Paul Eggert <eggert@twinsun.com>
5484

5493
5494 * po/LINGUAS: Add da.
5495

5507 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
5508 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5509 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
5510 locations are requested.
5511 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
5512 locations are requested.
5513
5514 2002-12-12 Paul Eggert <eggert@twinsun.com>
5515
5516 Remove unportable casts and storage allocation tricks.
5517 While we're at it, remove almost all casts, since they
5518 usually aren't needed and are a sign of trouble.
5519
5520 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
5521
5522 * src/derives.c (derives_compute): Do not subtract NTOKENS from
5523 the pointer DSET returned by malloc; this isn't portable.
5524 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
5525 Similarly for DERIVES.
5526 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
5527 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
5528 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
5529
5530 * src/derives.c (derives_compute): Do not bother invoking
5531 int_of_rule_number, since rule numbers are integers.
5532
5533 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
5534 rather than XMALLOC (char, N).
5535

5537
5538 * src/gram.h (symbol_number_as_item_number,
5539 item_number_as_symbol_number, rule_number_as_item_number,
5540 item_number_as_rule_number):
5541 Now inline functions rather than macros, to avoid casts.
5542 * src/state.h (state_number_as_int): Likewise.
5543 * src/tables.c (state_number_to_vector_number,
5544 symbol_number_to_vector_number): Likewise.
5545
5546 * src/gram.h (int_of_rule_number): Remove; no longer used.
5547
5548 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
5549 since the resulting storage is always stored into.
5550
5551 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
5552 where it's needed.
5553
5554 * src/muscle_tab.c (muscle_m4_output):
5555 Now inline. Return bool, not int.
5556 * src/state.c (state_compare): Likewise.

5563 New function, to avoid casts.
5564 * src/state.c (state_comparator, stage_hasher): Likewise.
5565 * src/symtab.c (symbol_check_defined_processor,
5566 symbol_check_alias_consistency_processor, symbol_pack_processor,
5567 symbol_translation_processor, hash_symbol_comparator,
5568 hash_symbol_hasher): Likewise.
5569 * src/uniqstr.c (uniqstr_print_processor): Likewise.
5570 * src/muscle_tab.c (muscles_m4_output):
5571 Use new functions instead of casting old functions unportably.
5572 * src/state.c (state_hash_new): Likewise.
5573 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
5574 symbols_token_translations_init):
5575 Likewise.
5576 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
5577
5578 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
5579 var instead of casting to long, to avoid casts.
5580 (prepare_states): Use MALLOC rather than alloca, so that we don't
5581 have to worry about alloca.
5582 * src/state.c (state_hash_lookup): Likewise.
5583
5584 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
5585 local var instead of casting to unsigned char, to avoid casts.
5586
5587 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
5588 STATE_ALLOC): Remove.
5589 (transitions_new, errs_new, reductions_new, state_new): Use malloc
5590 rather than calloc, and use offsetof to avoid allocating slightly
5591 too much storage.
5592 (state_new): Initialize all members.
5593
5594 * src/state.c (state_hash): Use unsigned accumulator, not signed.
5595
5596 * src/symtab.c (symbol_free): Remove; unused.
5597 (symbol_get): Remove cast in lhs of assignment.
5598 (symbols_do): Now static. Accept generic arguments, not
5599 hashing-related ones.
5600
5601 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
5602 (symbol_processor): Remove.
5603 (symbols_do): Remove decl; now static.
5604
5605 * src/system.h (alloca): Remove; decl no longer needed.
5606 (<stddef.h>): Include, for offsetof.
5607 (<inttypes.>, <stdint.h>): Include if available.
5608 (uintptr_t): New type, if system lacks it.
5609 (CALLOC, MALLOC, REALLOC): New macros.
5610 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
5611 new macros.
5612
5613 * src/tables.c (table_size): Now int, to pacify GCC.
5614 (table_grow, table_ninf_remap): Use signed table size.
5615 (save_row): Don't bother initializing locals when not needed.
5616 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
5617 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
5618
5619 * src/vcg.h: Correct misspellings.
5620
5621 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
5622
5623
5624 * src/getargs.c (getargs): Don't assume EOF == -1.
5625
5626 2002-12-09 Paul Eggert <eggert@twinsun.com>
5627
5628 Change identifier spellings to avoid collisions with names
5629 that are reserved by POSIX.
5630
5631 Don't use names ending in _t, since POSIX reserves them.
5632 For consistency, remove _e and _s endings -- they're weren't
5633 needed to remove ambiguity. All uses changed.
5634 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
5635 turn was just renamed from struniq_t.
5636 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
5637 which in turn was just renamed from struniq_processor_t.
5638 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
5639 in turn was renamed from hash_compare_struniq_t.

5708 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
5709 value_t_as_yystype -> value_as_yystype.
5710
5711 Don't include <errno.h> in the mainstream code, since it
5712 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
5713 * lib/get-errno.c, lib/get-errno.h: New files.
5714 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
5715 get-errno.c.

5717 * src/output.c (output_skeleton): Likewise.
5718 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno

5724 (TAB_EXT): Renamed from EXT_TAB.
5725 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
5726
5727 Avoid str[a-z]*, since <string.h> reserves that name space.
5728 Change all instances of "struniq" in names to "uniqstr", and
5729 likewise for "STRUNIQ" and "UNIQSTR".
5730 * src/uniqstr.c: Renamed from src/struniq.c.
5731 * src/uniqstr.h: Renamed from src/struniq.h.
5732 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

5742 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
5743 (N_EXPAND): Renamed from N_STRETCH.
5744
5745 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
5746 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
5747 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

5762 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
5763 G_NODE_ALIGNEMENT.
5764
5765
5766 * lib/timevar.c (timevar_report): Renamed from time_report,
5767 for consistency with other names.
5768 * lib/timevar.h (timevar_report): New decl.
5769 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
5770
5771
5772 Sort include-file uses.
5773
5774 Reorder all include files under src to be in the order "system.h".
5775 then the ../lib include files in angle brackets (alphabetized),
5776 then the . include files in double-quotes (alphabetized). Fix
5777 dependency breakages encountered in this process, as follows:
5778 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
5779 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
5780 * src/state.h: Include "symtab.h".
5781
5782 2002-12-08 Paul Eggert <eggert@twinsun.com>
5783
5784 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
5785 since this causes problems when __file__ contains character
5786 sequences like "@" that are treated specially by src/scan-skel.l.
5787 Instead, just use the file's basename. This fixes the bug
5788 reported by Martin Mokrejs in
5789 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
5790
5791 2002-12-06 Paul Eggert <eggert@twinsun.com>
5792
5793 Add support for rules that do not have trailing semicolons, as
5794 POSIX requires. Improve the quality of locations in Bison
5795 diagnostics.
5796
5797 * src/location.c: Include <quotearg.h>.
5798 (empty_location): Now const.
5799 (location_print): New function. Follow the recommendation of the
5800 GNU Coding Standards for locations that span file boundaries.
5801 * src/location.h: Do not include <quotearg.h>; no longer needed.
5802 (boundary): New type.
5803 (location_t): Use it. This allows locations to span file boundaries.
5804 All member uses changed: file -> start.file or end.file (as needed),
5805 first_line -> start.line, first_column -> start.column,
5806 last_line -> end.line, last_column -> end.column.
5807 (equal_boundaries): New function.
5808 (LOCATION_RESET, LOCATION_STEP): Remove.
5809 (LOCATION_PRINT): Remove. All callers changed to use location_print.
5810 (empty_location): Now const.
5811 (location_print): New decl.
5812 * src/parse-gram.y (lloc_default): New function, which handles
5813 empty locations more accurately.
5814 (YYLLOC_DEFAULT): Use it.
5815 (%token COLON): Remove.
5816 (%token ID_COLON): New token.
5817 (rules): Use it.
5818 (declarations, rules): Remove trailing semicolon.

5821 (symbol_def): Remove empty actions; no longer needed.
5822 (rules_or_grammar_declaration): Remove trailing semicolon.
5823 (semi_colon.opt): Remove.
5824 * src/reader.h: Include location.h.
5825 (scanner_cursor): New decl.

5827 rolling our own.
5828 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
5829 of *loc.
5830 (STEP): Remove. No longer needed, now that adjust_location does
5831 the work. All uses removed.
5832 (scanner_cursor): New var.
5833 (adjust_location): Renamed from extend_location. It now sets
5834 *loc and adjusts the scanner cursor. All uses changed.
5835 Don't bother testing for CR.
5836 (handle_syncline): Remove location arg; now updates scanner cursor.
5837 All callers changed.
5838 (unexpected_end_of_file): Now accepts start boundary of token or
5839 comment, not location. All callers changed. Update scanner cursor,
5840 not the location.
5841 (SC_AFTER_IDENTIFIER): New state.
5842 (context_state): Renamed from c_context. All uses changed.
5843 (id_loc, code_start, token_start): New local vars.
5844 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
5845 processing of Yacc white space and equivalents here.
5846 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
5847 instead of returning ID immediately, since we need to search for
5848 a subsequent colon.
5849 (<INITIAL>"'", "\""): Save token_start.
5850 (<INITIAL>"%{", "{", "%%"): Save code_start.
5851 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
5852 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
5853 BEGIN context_state at end, not INITIAL.
5854 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
5855 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
5856 Return correct token start.
5857 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
5858 the start of a character, string or multiline comment is found.
5859 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
5860 Reduction): Adjust reported locations to match the more-precise
5861 results now expected.
5862 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
5863 * tests/reduce.at (Useless Rules, Reduced Automaton,
5864 Underivable Rules): Likewise.
5865 * tests/regression.at (Invalid inputs): No longer `expecting ";"
5866 or "|"' now that so many other tokens are allowed by the new grammar.
5867
5868 * src/complain.h (current_file): Remove duplicate decl;
5869 current_file is now owned by files.h.
5870 * src/complain.c, src/scan-gram.l: Include files.h.
5871
5872 2002-12-06 Paul Eggert <eggert@twinsun.com>
5873
5874 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
5875 promotes to int; it might be unsigned int.
5876 * data/yacc.c (yy_reduce_print): Likewise.
5877
5878 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
5879 be #defined in the prologue, not in the Bison declarations.
5880 This fixes Debian Bug 102878, reported by Shaul Karl.
5881
5882 2002-12-02 Paul Eggert <eggert@twinsun.com>
5883
5884 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
5885 * lib/strtoul.c: New file, from gnulib.
5886 This fixes a porting bug reported by Peter Klein in
5887 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
5888
5889 2002-11-30 Paul Eggert <eggert@twinsun.com>
5890
5891 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
5892 and put only a forward declaration in the prologue. This is for
5893 consistency with the other scanner helper functions.
5894
5895 Type clashes now generate warnings, not errors, since it
5896 appears that POSIX may allow some grammars with type clashes.
5897 * src/reader.c (grammar_current_rule_check): Warn about
5898 type clashes instead of complaining.
5899 * tests/input.at (Type Clashes): Expect warnings, not complaints.
5900
5901 Add Yacc library, since POSIX requires it.
5902 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
5903 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
5904 * lib/main.c, lib/yyerror.c: New files.
5905
5906 gram_error can be static; it need not be extern.
5907 * src/reader.h (gram_error): Remove decl.
5908 * src/parse-gram.y (gram_error): Now static. Add static decl.
5909 (print_token_value): Omit parameter names from forward decl,
5910 for consistency.
5911
5912 2002-11-29 Paul Eggert <eggert@twinsun.com>
5913
5914 * doc/bison.texinfo: Emphasize that yylex and yyerror must
5915 be declared before being used. E.g., one should typically
5916 declare them in the prologue. Use GNU coding style in examples.
5917 Put "const" consistently after the type it modifies. Mention
5918 that C99 supports "inline". Mention that yyerror traditionally
5919 returns "int".
5920
5921 %parse-param and %lex-param now take just one argument, the
5922 declaration; the argument name is deduced from the declaration.
5923
5924 * doc/bison.texinfo (Parser Function, Pure Calling, Error
5925 Reporting, Table of Symbols): Document this.
5926 * src/parse-gram.y (add_param): New function.
5927 (COMMA): Remove.
5928 (declaration): Implement new rule for %parse-param and %lex-param.
5929 * src/scan-gram.l: "," now elicits a warning, rather than being
5930 a token; this is more compatible with byacc.
5931 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
5932
5933 2002-11-27 Paul Eggert <eggert@twinsun.com>
5934
5935 Rename identifiers to avoid real and potential collisions.
5936
5937 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
5938 to avoid collision with lex macro described by Bruce Lilly in
5939 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5940 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
5941 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
5942 * src/parse-gram.y (print_token_value): Renamed from yyprint.
5943 All uses changed.
5944 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
5945 The name "yycontrol" violates the name space rules, and this stuff
5946 wasn't being used anyway.
5947 (input): Remove action; this stuff wasn't being used.
5948 (gram_error): Rename local variable yylloc -> loc.
5949 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
5950 (YY_DECL): Don't use "yy" at start of local variables.
5951 All uses changed, e.g., yylloc -> loc.
5952 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
5953 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
5954 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
5955 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
5956
5957 * src/parse-gram.y (gram_error): loc is now const *.
5958 * src/reader.h (gram_error): Likewise.
5959
5960 2002-11-24 Paul Eggert <eggert@twinsun.com>
5961
5962 Version 1.75c.
5963
5964 * tests/actions.at (Actions after errors): Use an output format
5965 more similar to that of the Printers and Destructors test.
5966 Test the position of the ';' token too.
5967 (Printers and Destructors): Likewise.
5968 (Printers and Destructors: %glr-parser): Remove for now, to avoid
5969 unnecessarily alarming people when the test fails.
5970
5971 * data/yacc.c (yyerrlab1): Move this label down, so that the
5972 parser does not discard the lookahead token if the user code
5973 invokes YYERROR. This change is required for POSIX conformance.
5974
5975 * lib/error.c: Sync with gnulib.
5976
5977 2002-11-22 Paul Eggert <eggert@twinsun.com>
5978
5979 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
5980 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
5981 * lib/xmalloc.c: Likewise.
5982
5983 2002-11-20 Paul Eggert <eggert@twinsun.com>
5984
5985 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
5986
5987 2002-11-20 Paul Eggert <eggert@twinsun.com>
5988
5989 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
5990 should use `if (! x) abort ();' rather than `assert (x);', and
5991 anyway it's one less thing to worry about configuring.
5992
5993 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
5994 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
5995 and replace all instances of assert with abort.
5996 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
5997 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
5998
5999 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
6000 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
6001 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
6002 hash_find_entry, hash_rehash, hash_insert): Likewise.
6003 * src/conflicts.c (resolve_sr_conflict): Likewise.
6004 * src/lalr.c (set_goto_map, map_goto): Likewise.
6005 * src/nullable.c (nullable_compute): Likewise.
6006 * src/output.c (prepare_rules, token_definitions_output): Likewise.
6007 * src/reader.c (packgram, reader): Likewise.
6008 * src/state.c (state_new, state_free, state_transitions_set,
6009 state_reduction_find): Likewise.
6010 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
6011 symbol_pack): Likewise.
6012 * src/tables.c (conflict_row, pack_vector): Likewise.
6013 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
6014 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
6015 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
6016 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
6017
6018 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
6019 (ARGMATCH_CONSTRAINT): New macro.
6020 (ARGMATCH_ASSERT): Use it.
6021
6022 * src/system.h (verify): New macro.
6023 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
6024 rather than assert.
6025 * src/tables.c (tables_generate): Likewise.
6026
6027 * src/struniq.c (struniq_assert): Now returns void, and aborts
6028 if the assertion is false.
6029 (struniq_assert_p): Remove.
6030 * src/struniq.h: Likewise.
6031
6032 2002-11-18 Paul Eggert <eggert@twinsun.com>
6033
6034 * data/glr.c (yygetLRActions): Replace `yyindex' with
6035 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
6036 This fixes the regression with Sun ONE Studio 7 cc that I reported in
6037 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
6038
6039 2002-11-18 Akim Demaille <akim@epita.fr>
6040
6041 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
6042 space.
6043 From Tim Van Holder.
6044
6045 2002-11-17 Paul Eggert <eggert@twinsun.com>
6046
6047 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
6048 to "SyntaxError" for consistency with my 2002-11-15 change.
6049
6050 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
6051 not define to {}, since this breaks the common use of `YYDPRINTF
6052 ((...));' if a single statement is desired (e.g. before `else').
6053 Work around GCC warnings by surrounding corresponding calls with
6054 {} if needed.
6055 (yyhasResolvedValue): Remove unused function.
6056 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
6057 loop body.
6058 (yyreportSyntaxError): Renamed from yyreportParseError.
6059 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
6060 All uses changed.
6061 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
6062 extern when possible. Remove unused initializations.
6063
6064 2002-11-16 Akim Demaille <akim@epita.fr>
6065
6066 Augment the similarity between GLR and LALR traces.
6067
6068 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
6069 (YY_REDUCE_PRINT): New.
6070 (yyparse): Use them.
6071 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
6072 YYDPRINT here.
6073 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
6074 state reached after the reduction/recovery, since...
6075 (yyparse, yyprocessOneStack): Report the state we are entering in.
6076
6077 2002-11-16 Akim Demaille <akim@epita.fr>
6078
6079 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
6080 Add support for --trace=skeleton.
6081 * src/scan-skel.l: %option debug.
6082 Scan strings of non-@ or \n instead of character by character.
6083 (scan_skel): Handle trace_skeleton.
6084 (QPUTS): New.
6085 (@output_parser_name@, @output_header_name@): ``Restore'' their
6086 support (used to be M4 macros).
6087 * data/yacc.c: Quote larger chunks, a la glr.c.
6088 * data/lalr1.cc: Likewise.
6089 The header guards are no longer available, so use some other
6090 string than `YYLSP_NEEDED'.
6091
6092 2002-11-16 Akim Demaille <akim@epita.fr>
6093
6094 Make the ``Printers and Destructors'' test more verbose, taking
6095 `yacc.c''s behavior as (possibly wrong) reference.
6096
6097 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
6098 instead of fprint on stdout.
6099 Set and report the last_line of the symbols.
6100 Consistently display values and locations.
6101
6102 2002-11-16 Paul Eggert <eggert@twinsun.com>
6103
6104 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
6105
6106 2002-11-15 Paul Eggert <eggert@twinsun.com>
6107
6108 * tests/actions.at (Actions after errors): New test case.
6109
6110 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
6111 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
6112 tests/action.at, tests/calc.at, tests/conflicts.at,
6113 tests/cxx-type.at, tests/regression.at:
6114 "parse error" -> "syntax error" for POSIX compatibility.
6115 "parsing stack overflow..." -> "parser stack overflow" so
6116 that code matches Bison documentation.
6117
6118 2002-11-15 Akim Demaille <akim@epita.fr>
6119
6120 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
6121 take two BRACED_CODE, not two string_content.
6122 Free the scanner's obstack when we are done.
6123 (code_content): New.
6124 * tests/calc.at: Adjust.
6125 * doc/bison.texinfo: Adjust.
6126 Also, make sure to include the `,' for these declarations.
6127
6128 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
6129
6130 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
6131 definition; avoids potential autoreconf problems.
6132
6133 2002-11-15 Akim Demaille <akim@epita.fr>
6134
6135 Always check the value returned by yyparse.
6136
6137 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
6138 returned by yyparse.
6139 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
6140 Adjust calls.
6141 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
6142 returned by yyparse.
6143
6144 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6145
6146 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
6147 on input.at test.
6148
6149 2002-11-14 Paul Eggert <eggert@twinsun.com>
6150
6151 * src/output.c (output_skeleton): Call xfopen instead of
6152 duplicating xfopen's body.
6153
6154 Fix bugs reported by Nelson H. F. Beebe in
6155 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
6156
6157 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
6158 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
6159 Group compiler. Instead, use "$CC -E bar.c". Include the .h
6160 file twice in the grammar, as an extra check.
6161
6162 * tests/input.at (Torturing the Scanner): Surround the
6163 backslash-newline tests with "#if 0", to make it less likely that
6164 we'll run into compiler bugs. Bring back solitary \ inside
6165 comment, but add a closing comment to work around HP C bug. Don't
6166 test backslash-newline in C character constant.
6167
6168 2002-11-14 Akim Demaille <akim@epita.fr>
6169
6170 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
6171 status of the compiler.
6172 Calling `exit 1' is no longer needed.
6173 Reported by Nelson H. F. Beebe.
6174
6175 2002-11-14 Akim Demaille <akim@epita.fr>
6176
6177 * tests/atlocal.in (CPPFLAGS): We have config.h.
6178 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
6179 New.
6180 * tests/actions.at, tests/calc.at, tests/conflicts.at,
6181 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
6182 * tests/regression.at, tests/torture.at: Use them for all the
6183 grammars that are to be compiled.
6184 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
6185 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
6186 * doc/bison.texinfo (GLR Parsers): Document `inline'.
6187
6188 2002-11-14 Akim Demaille <akim@epita.fr>
6189
6190 * doc/bison.texinfo: Various formatting changes (alignments in
6191 samples, additional @group/@end group, GCS in samples.
6192 Use @deffn instead of simple @table to define the directives,
6193 macros, variables etc.
6194
6195 2002-11-13 Paul Eggert <eggert@twinsun.com>
6196
6197 Fix some bugs reported by Albert Chin-A-Young in
6198 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
6199
6200 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
6201 -o c"; the HP C compiler chatters during compilation.
6202 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
6203 * tests/headers.at (export YYLTYPE): Likewise.
6204
6205 * tests/input.at (Torturing the Scanner): Remove lines containing
6206 solitary backslashes, as they tickle a bug in the HP C compiler.
6207
6208 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
6209 comments, since they're not portable. Use GNU coding style.
6210
6211 2002-11-13 Akim Demaille <akim@epita.fr>
6212
6213 * data/yacc.c: Leave bigger chunks of quoted text.
6214 (YYDSYMPRINTF): New.
6215 Use it to report symbol activities.
6216 * data/glr.c (YYDSYMPRINTF): New.
6217 Use it.
6218
6219 2002-11-12 Paul Eggert <eggert@twinsun.com>
6220
6221 Version 1.75b.
6222
6223 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
6224 (yyglrReduce): Return yyok, not 0.
6225 This should avoid the enumerated-type warnings reported
6226 by Nelson H. F. Beebe in
6227 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
6228
6229 * lib/bbitset.h (BITSET_INLINE): Remove.
6230 * lib/bitset.h [! BITSET_INLINE]: Remove.
6231 (bitset_set, bitset_reset, bitset_test): Rename local vars
6232 to avoid shadowing warnings by GCC.
6233
6234 * data/glr.c (inline): Remove #define. It's the user's
6235 responsibility to #define it away, just like 'const'.
6236 This fixes one of the bugs reported by Nelson H. F. Beebe in
6237 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
6238
6239 * Makefile.maint (po-check): Scan .l and .y files instead of the
6240 .c and the .h files that they generate. This fixes the bug
6241 reported by Tim Van Holder in:
6242 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
6243 Look for N_ as well as for _. Try to avoid matching #define for
6244 N_ and _.
6245 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
6246 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
6247 * src/scan-gram.l: Revamp regular expressions so that " and '
6248 do not confuse xgettext.
6249
6250 * src/struniq.h (struniq_new): Do not declare the return type
6251 to be 'const'; this violates the C standard.
6252 * src/struniq.c (struniq_new): Likewise.
6253
6254 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
6255
6256 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
6257 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
6258 linker.
6259
6260 2002-11-12 Akim Demaille <akim@epita.fr>
6261
6262 * Makefile.maint: Sync with Autoconf:
6263 (local_updates): New.
6264
6265 2002-11-12 Akim Demaille <akim@epita.fr>
6266
6267 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
6268
6269 2002-11-12 Akim Demaille <akim@epita.fr>
6270
6271 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the

6397
6398 2002-11-11 Paul Eggert <eggert@twinsun.com>
6399
6400 Revamp to fix many (but not all) of the C- and M4-related quoting
6401 problems. Among other things, this fixes the Bison bug reported
6402 by Jan Hubicka when processing the Bash grammar; see:
6403 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
6404
6405 Use new @ escapes consistently. Represent brackets with @{ and @}
6406 rather than @<:@ and @:>@, since this works a bit better with dumb
6407 editors like vi. Represent @ with @@, since @ is now consistently
6408 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6409 __ofile__, to avoid unexpected expansions. Similarly, use @output
6410 rather than #output.
6411
6412 * data/c.m4 (b4_copyright): Omit file name from comment, since
6413 the file name could contain "*/".
6414 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6415 be quoted. All uses changed.
6416
6417 * data/glr.c: Use new @ escapes consistently.
6418 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
6419 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
6420 Remove, since they couldn't handle arbitrary characters in file
6421 names.
6422 * data/lalr1.cc: Likewise.
6423 * data/yacc.c: Likewise.
6424
6425 * src/files.c (output_infix): Remove; all uses removed.
6426 * src/files.h: Likewise.
6427
6428 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
6429 mishandled funny characters in file names, and anyway it isn't
6430 needed any more.
6431 * data/yacc.c: Likewise.
6432 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
6433
6434 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
6435 * data/yacc.c: Likewise.
6436
6437 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
6438 strings now.
6439 (muscle_init): Quote filename as a C string.
6440 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
6441 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
6442 * src/output.c (escaped_file_name_output): New function.
6443 (prepare_symbols): Quote tokens for M4.
6444 (prepare): Don't insert output_infix, output_prefix,
6445 output_parser_name, output_header_name; this is now down by scan-skel.
6446 Insert skeleton as a C string.
6447
6448 * src/output.c (user_actions_output, symbol_destructors_output,
6449 symbol_printers_output): Quote filenames for C and M4.
6450 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6451
6452 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
6453 escapes other than \\ and \'; this simplifies the code.
6454 (<SC_STRING>): Likewise, for \\ and \".
6455 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6456 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6457 Use new escapes @{ and @} for [ and ].
6458
6459 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6460 them with auto vars.
6461 Switch to new escape scheme, where @ is the escape character uniformly.
6462 Abort if a stray escape character is found. Avoid unbounded input
6463 buffer when parsing non-escaped text.
6464
6465 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
6466 __oline__, #output, $@, and @{ do not have unintended meanings.
6467
6468 2002-11-09 Paul Eggert <eggert@twinsun.com>
6469
6470 Fix the test failure due to GCC warnings described in
6471 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
6472 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
6473 evaluate to 0 if it's impossible for NINF to be in the respective
6474 table.
6475 (yygetLRActions, yyrecoverParseError): Use them.
6476
6477 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6478 counted in the token inserted at end of file. Now takes
6479 location_t *, not location_t, so that the location can be
6480 adjusted. All uses changed.
6481
6482 * tests/regression.at (Invalid inputs): Adjust wording in
6483 diagnostic to match the new behavior.
6484
6485 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
6486 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
6487 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
6488 abort ();'. This reduces the runtime of the "Many lookaheads"
6489 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
6490 GCC 3.2.
6491
6492 2002-11-07 Paul Eggert <eggert@twinsun.com>
6493
6494 * src/parse-gram.y (CHARACTER): Remove unused token.
6495 All uses removed.
6496
6497 * src/scan-gram.l: Remove stack option. We no longer use the
6498 stack, since the stack was never deeper than 1; instead, use the
6499 new auto var c_context to record the stacked value.
6500
6501 Remove nounput option. At an unexpected end of file, we now unput
6502 the minimal input necessary to end cleanly; this simplifies the
6503 code.
6504
6505 Avoid unbounded token sizes where this is easy.
6506
6507 (unexpected_end_of_file): New function.
6508 Use it to systematize the error message on unexpected EOF.
6509 (last-string): Now auto, not static.
6510 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
6511 (scanner_last_string_free): Remove; not used.
6512 (percent_percent_count): Move decl to just before use.
6513 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
6514 not the (never otherwised-used) CHARACTER.
6515
6516 2002-11-07 Akim Demaille <akim@epita.fr>
6517
6518 Let yyerror always receive the msg as last argument, so that
6519 yyerror can be variadic.
6520
6521 * data/yacc.c (b4_yyerror_args): New.
6522 Use it when calling yyerror.
6523 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
6524 Use it when calling yyerror.

6531 #line should have quoted strings.
6532 Ideally, this should be done by m4_quotearg.
6533
6534 * src/scan-skel.l: Include quotearg.h.
6535 Quote __ofile__.
6536 * src/output.c (symbol_printers_output)
6537 (symbol_destructors_output): Quote the file name.
6538
6539 2002-11-06 Akim Demaille <akim@epita.fr>
6540
6541 * tests/regression.at (Invalid inputs): Adjust to the recent
6542 messages.
6543
6544 2002-11-06 Akim Demaille <akim@epita.fr>
6545
6546 Restore --no-lines.
6547 Reported by Jim Kent.
6548
6549 * data/c.m4 (b4_syncline): New.
6550 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
6551 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
6552 * src/output.c (user_actions_output): Likewise.
6553 (prepare): Define 'b4_synclines_flag'.
6554 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
6555
6556 2002-11-06 Akim Demaille <akim@epita.fr>
6557
6558 * src/main.c (main): Free `infile'.
6559 * src/scan-gram.l (handle_syncline): New.
6560 Recognize `#line'.
6561 * src/output.c (user_actions_output, symbol_destructors_output)
6562 (symbol_printers_output): Use the location's file name, not
6563 infile.
6564 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6565
6566 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6567
6568 * src/tables.c (matching_state): Don't allow states to match if
6569 either has GLR conflict entries.
6570
6571 2002-11-05 Paul Eggert <eggert@twinsun.com>
6572
6573 * src/scan-gram.l: Use more accurate diagnostics, e.g.
6574 "integer out of range" rather than "invalid value".
6575 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
6576 accordingly.
6577
6578 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
6579 Also, remove one static variable in the scanner.
6580
6581 * src/scan-gram.l (braces_level): Now auto, not static.
6582 Initialize to zero if the compiler is being picky.
6583 (INITIAL): Clear braces_level instead of incrementing it.
6584 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
6585 as POSIX 1003.1-2001 requires.
6586 * src/system.h (IF_LINT): New macro, taken from coreutils.
6587 * configure.ac: Define "lint" if --enable-gcc-warnings.
6588
6589 2002-11-05 Akim Demaille <akim@epita.fr>
6590
6591 * src/scan-gram.l: When it starts with `%', complain about the
6592 whole directive, not just that `invalid character: %'.
6593
6594 2002-11-04 Akim Demaille <akim@epita.fr>
6595
6596 * Makefile.maint: Update from Autoconf.

6602 and yyerror.
6603 Have yyerror `use' its arguments.

6605 returns true when location & yacc & pure & parse-param.
6606 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
6607
6608 2002-11-04 Akim Demaille <akim@epita.fr>
6609
6610 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
6611 clashes.
6612 * src/scan-gram.l: Use [\'] instead of ['] to pacify
6613 font-lock-mode.
6614 Use complain_at.
6615 Use quote, not quote_n since LOCATION_PRINT no longer uses the
6616 slot 0.

6690 Use {splice} wherever C allows backslash-newline.
6691 YY_STEP after space, newline, vertical-tab.

6701 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
6702 as well as \000. Check for UCHAR_MAX, not 255.
6703 Allow \x with an arbitrary positive number of digits, as in C.
6704 Check for overflow here.
6705 Allow \? and UCNs, for compatibility with C.
6706
6707 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
6708 with quote slot used by complain_at.
6709
6710 * tests/input.at: Add tests for backslash-newline, m4 quotes
6711 in symbols, long literals, and funny escapes in strings.
6712
6713 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
6714 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
6715 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
6716 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
6717 * m4/mbswidth.m4: New file, from GNU coreutils.
6718
6719 * doc/bison.texinfo (Grammar Outline): Document // comments.
6720 (Symbols): Document that trigraphs have no special meaning in Bison,
6721 nor is backslash-newline allowed.
6722 (Actions): Document that trigraphs have no special meaning.
6723
6724 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
6725 no longer used.
6726
6727 2002-11-02 Paul Eggert <eggert@twinsun.com>
6728
6729 * src/reader.c: Don't include quote.h; not needed.
6730 (get_merge_function): Reword warning to be consistent with
6731 type clash diagnostic in grammar_current_rule_check.
6732
6733 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
6734 bug in trigraph handling.
6735
6736 * src/output.c (prepare_symbols): When printing token names,
6737 escape "[" as "@<:@" and likewise for "]".
6738
6739 * src/system.h (errno): Remove declaration, as we are now
6740 assuming C89 or better, and C89 guarantees errno.
6741
6742 2002-10-30 Paul Eggert <eggert@twinsun.com>
6743
6744 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
6745 Check for close failures.
6746 * src/files.h (xfclose): Return void, not int, since it always
6747 returned zero.
6748 * src/files.c (xfclose): Likewise. Report I/O error if ferror
6749 indicates one.
6750 * src/output.c (output_skeleton): Use xfclose rather than fclose
6751 and ferror. xfclose now checks ferror.
6752
6753 * data/glr.c (YYLEFTMOST_STATE): Remove.
6754 (yyreportTree): Use a stack-based leftmost state. This avoids
6755 our continuing battles with bogus warnings about initializers.
6756
6757 2002-10-30 Akim Demaille <akim@epita.fr>
6758
6759 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
6760 #if.
6761
6762 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6763
6764 * tests/glr-regr1.at: New test for reported regressions.
6765 * tests/testsuite.at: Add glr-regr1.at test.
6766 * tests/Makefile.am: Add glr-regr1.at test.
6767
6768 2002-10-24 Paul Eggert <eggert@twinsun.com>
6769
6770 Version 1.75a.
6771
6772 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
6773 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
6774 we use malloc. Don't assume 'A' through 'Z' are contiguous.
6775 Don't assume strdup exists; POSIX says its an XSI extension.
6776 Check for buffer overflow on input.
6777
6778 2002-10-24 Akim Demaille <akim@epita.fr>
6779
6780 * src/output.c (output_skeleton): Don't disable M4sugar comments
6781 too soon: it results in comments being expanded.
6782 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
6783 first output.
6784
6785 2002-10-24 Akim Demaille <akim@epita.fr>
6786
6787 * data/yacc.c (m4_int_type): New.
6788 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
6789 char' as only yacc.c wants K&R portability.
6790 * data/glr.c (yysigned_char): Remove.
6791 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
6792 Reported by Quoc Peyrot.
6793
6794 2002-10-23 Paul Eggert <eggert@twinsun.com>
6795
6796 * src/main.c (main): With --trace=time, report times even if a
6797 non-fatal error occurs. Formerly, the times were reported in some
6798 such cases but not in others.
6799 * src/reader.c (reader): Just return if a complaint has been issued,
6800 instead of exiting, so that 'main' can report times.
6801
6802 2002-10-22 Akim Demaille <akim@epita.fr>
6803
6804 * src/system.h: Include sys/types.
6805 Reported by Bert Deknuydt.
6806
6807 2002-10-23 Paul Eggert <eggert@twinsun.com>
6808
6809 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
6810 Suggested by Art Haas.
6811
6812 2002-10-22 Paul Eggert <eggert@twinsun.com>
6813
6814 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
6815 decl; not needed any more.
6816 * src/main.c (main): Use return to exit, undoing yesterday's change.
6817 The last OS that we could find where this wouldn't work is
6818 SunOS 3.5, and that's too old to worry about now.
6819
6820 * data/glr.c (struct yyltype): Define members even when not
6821 doing locations. This is more consistent with yacc.c, and it
6822 works around the following bug reports:
6823 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
6824 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
6825
6826 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
6827 @acronym consistently. Standardize on "Yacc" instead of "YACC",
6828 "Algol" instead of "ALGOL". Give a bit more history about BNF.
6829
6830 2002-10-22 Akim Demaille <akim@epita.fr>
6831
6832 * data/README: New.
6833
6834 2002-10-21 Paul Eggert <eggert@twinsun.com>
6835
6836 Be consistent about 'bool'; the old code used an enum in one
6837 module and an int in another, and this violates the C standard.
6838 * m4/stdbool.m4: New file, from coreutils 4.5.3.
6839 * configure.ac (AC_HEADER_STDBOOL): Add.
6840 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
6841 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
6842 * src/symtab.c (hash_compare_symbol_t): Likewise.
6843 * src/system.h (bool, false, true): Use a definition consistent
6844 with ../lib/hash.c. All uses changed.
6845
6846 * src/complain.c (warning_issued): Renamed from warn_message_count,
6847 so that we needn't worry about integer overflow (!).
6848 Now of type bool. All uses changed.
6849 (complaint_issued): Renamed from complain_message_count; likewise.
6850
6851 * src/main.c (main): Use exit to exit with failure.
6852
6853 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
6854 rather than 1 and 0.
6855 * src/main.c (main): Likewise.
6856 * src/getargs.c (getargs): Likewise.
6857 * src/reader.c (reader): Likewise.
6858
6859 * src/getarg.c (getargs): Remove duplicate code for
6860 "Try `bison --help'".
6861
6862 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
6863 What was that "2" for?
6864
6865 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
6866 * src/getargs.c (usage): Likewise.
6867
6868 * src/getargs.c (getargs): When there are too few operands, report
6869 the last one. When there are too many, report the first extra
6870 one. This is how diffutils does it.
6871
6872 2002-10-20 Paul Eggert <eggert@twinsun.com>
6873
6874 Remove K&R vestiges.
6875 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
6876 * src/complain.c (VA_START): Remove. Assume prototypes.
6877 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
6878 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
6879 fatal): Assume prototypes.
6880 * src/complain.h: Assume prototypes.
6881 * src/system.h (PARAMS): Remove.
6882 Include <limits.h> unconditionally, since it's guaranteeed even
6883 for a freestanding C89 compiler.
6884 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
6885 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
6886
6887 2002-10-20 Akim Demaille <akim@epita.fr>
6888
6889 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
6890 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
6891 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
6892 (yyresolveStates, yyresolveAction, yyresolveStack)
6893 (yyprocessOneStack): Use them.
6894 (yy_reduce_print): New.
6895 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
6896
6897 2002-10-20 Akim Demaille <akim@epita.fr>
6898
6899 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
6900 arguments and output `void'.
6901 (b4_c_function): Rename as...
6902 (b4_c_function_def): this.
6903 (b4_c_function_decl, b4_c_ansi_function_def)
6904 (b4_c_ansi_function_decl): New.
6905 Change the interpretation of the arguments: before `int, foo', now
6906 `int foo, foo'.
6907 * data/yacc.c (yyparse): Prototype and define thanks to these.
6908 Adjust b4_c_function_def uses.
6909 * data/glr.c (yyparse): Likewise, but ANSI only.
6910
6911 2002-10-20 Akim Demaille <akim@epita.fr>
6912
6913 * src/output.c (prepare): Move the definition of `tokens_number',
6914 `nterms_number', `undef_token_number', `user_token_number_max'
6915 to...
6916 (prepare_tokens): Here.
6917 (prepare_tokens): Rename as...
6918 (prepare_symbols): this.
6919 (prepare): Move the definition of `rules_number' to...
6920 (prepare_rules): here.
6921 (prepare): Move the definition of `last', `final_state_number',
6922 `states_number' to...
6923 (prepare_states): here.
6924 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
6925
6926 2002-10-20 Akim Demaille <akim@epita.fr>
6927
6928 * src/tables.h, src/tables.c, src/output.c: Comment changes.
6929
6930 2002-10-20 Akim Demaille <akim@epita.fr>
6931
6932 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
6933 * data/c.m4: here.
6934
6935 2002-10-20 Akim Demaille <akim@epita.fr>
6936
6937 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
6938 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
6939 `pair'.
6940 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
6941 `name' to...
6942 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
6943 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
6944 These.
6945
6946 2002-10-19 Paul Eggert <eggert@twinsun.com>
6947
6948 Do not create a temporary file, as that involves security and
6949 cleanup headaches. Instead, use a pair of pipes.
6950 Derived from a suggestion by Florian Krohm.
6951 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
6952 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
6953 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
6954 (BISON_PREREQ_SUBPIPE): Add.
6955 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
6956 Add subpipe.h, subpipe.c.
6957 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
6958 * po/POTFILES.in: Add lib/subpipe.c.
6959 * src/output.c: Include "subpipe.h".
6960 (m4_invoke): Remove decl.
6961 (scan_skel): New decl.
6962 (output_skeleton): Use pipe rather than temporary file for m4 input.
6963 Check that m4sugar.m4 is readable, to avoid deadlock.
6964 Check for pipe I/O error.
6965 * src/scan-skel.l (readpipe): Remove decl.
6966 (scan_skel): New function, to be used in place of m4_invoke.
6967 Read from stream rather than file.
6968
6969 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
6970 float, as this generates a warning on Solaris 8 + GCC 3.2 with
6971 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
6972 this generates a more-accurate value anyway.
6973
6974 * lib/timevar.c (timervar_accumulate): Rename locals to
6975 avoid confusion with similarly-named more-global.
6976 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
6977
6978 * src/output.c (prepare): Use xstrdup to convert char const *
6979 to char *, to avoid GCC warning.
6980
6981 2002-10-19 Akim Demaille <akim@epita.fr>
6982
6983 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
6984 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
6985 Use them to have `calc.y' ready for %pure-parser.
6986 * data/yacc.c (YYLEX): Pass a yylex return type to
6987 b4_c_function_call.
6988
6989 2002-10-19 Akim Demaille <akim@epita.fr>
6990
6991 Prototype support of %lex-param and %parse-param.
6992
6993 * src/parse-gram.y: Add the definition of the %lex-param and
6994 %parse-param tokens, plus their rules.
6995 Drop the `_' version of %glr-parser.
6996 Add the "," token.
6997 * src/scan-gram.l (INITIAL): Scan them.
6998 * src/muscle_tab.c: Comment changes.
6999 (muscle_insert, muscle_find): Rename `pair' as `probe'.
7000 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
7001 (muscle_entry_s): The `value' member is no longer const.
7002 Adjust all dependencies.
7003 * src/muscle_tab.c (muscle_init): Adjust: use
7004 MUSCLE_INSERT_STRING.
7005 Initialize the obstack earlier.
7006 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
7007 (muscle_pair_list_grow): New.
7008 * data/c.m4 (b4_c_function_call, b4_c_args): New.
7009 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
7010 * tests/calc.at: Use %locations, not --locations.
7011 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
7012
7013 2002-10-19 Akim Demaille <akim@epita.fr>
7014
7015 * src/getargs.c (usage): Take status as argument and exit
7016 accordingly.
7017 Report the traditional `Try ... --help' message when status != 0.
7018 (usage, version): Don't take a FILE * as arg, it is pointless.
7019 (getargs): When there is an incorrect number of arguments, make it
7020 an error, and report it GNUlically thanks to `usage ()'.
7021
7022 2002-10-18 Paul Eggert <eggert@twinsun.com>
7023
7024 * data/glr.c (yyreportParseError): Don't assume that sprintf
7025 yields the length of the printed string, as this is not true
7026 on SunOS 4.1.4. Reported by Peter Klein.
7027
7028 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
7029 * tests/conflicts.at (%nonassoc and eof): Likewise.
7030 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
7031
7032 2002-10-17 Akim Demaille <akim@epita.fr>
7033
7034 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
7035 * src/getargs.c (trace_types, trace_args): Adjust.
7036 * src/reader.c (grammar_current_rule_prec_set)
7037 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
7038 Standardize error messages.
7039 And s/@prec/%prec/!
7040 (reader): Use trace_flag to enable scanner/parser debugging,
7041 instead of an adhoc scheme.
7042 * src/scan-gram.l: Remove trailing debugging code.
7043
7044 2002-10-16 Paul Eggert <eggert@twinsun.com>
7045
7046 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
7047 MUSCLE_TAB_H.
7048
7049 * NEWS: Officially drop support for building Bison with K&R C,
7050 since it didn't work anyway and it's not worth worrying about.
7051 * Makefile.maint (wget_files): Remove ansi2knr.c.
7052 (ansi2knr.c-url_prefix): Remove.
7053 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
7054 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
7055 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
7056
7057 2002-10-15 Paul Eggert <eggert@twinsun.com>
7058
7059 Stop using the "enum_" trick for K&R-style function definitions;
7060 it confused me, and I was the author! Instead, assume that people
7061 who want to use K&R C compilers (when using these modules in GCC,
7062 perhaps?) will run ansi2knr.
7063
7064 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
7065 All uses of "enum_" changed to "enum ".
7066 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
7067 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
7068
7069 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,
7070 abitset_and_or_cmp, abitset_andn, abitset_andn_cmp,
7071 abitset_andn_or, abitset_andn_or_cmp, abitset_bytes, abitset_copy,
7072 abitset_copy1, abitset_disjoint_p, abitset_empty_p,
7073 abitset_equal_p, abitset_init, abitset_list, abitset_list_reverse,
7074 abitset_not, abitset_ones, abitset_or, abitset_or_and,
7075 abitset_or_and_cmp, abitset_or_cmp, abitset_reset, abitset_set,
7076 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
7077 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
7078 Use function prototypes; this removes the need for declaring
7079 static functions simply to provide their prototypes.
7080 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,
7081 bitset_andn_or_, bitset_andn_or_cmp_, bitset_bytes, bitset_copy_,
7082 bitset_count_, bitset_create, bitset_dump, bitset_first,

7086 bitset_print, bitset_release_memory, bitset_toggle_,
7087 bitset_type_choose, bitset_type_get, bitset_type_name_get,
7088 debug_bitset): Likewise.
7089 * lib/bitset.h (bitset_set, bitset_reset, bitset_test): Likewise.
7090 * lib/bitset_stats.c (bitset_log_histogram_print,
7091 bitset_percent_histogram_print, bitset_stats_and,
7092 bitset_stats_and_cmp, bitset_stats_and_or,

7133 2002-10-14 Akim Demaille <akim@epita.fr>
7134
7135 Version 1.75.
7136
7137 2002-10-14 Akim Demaille <akim@epita.fr>
7138
7139 * tests/Makefile.am (maintainer-check-posix): New.
7140
7141 2002-10-14 Akim Demaille <akim@epita.fr>
7142
7143 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
7144 member.
7145
7146 2002-10-14 Akim Demaille <akim@epita.fr>
7147
7148 * src/tables.c (table_ninf_remap): base -> tab.
7149 Reported by Matt Rosing.
7150
7151 2002-10-14 Paul Eggert <eggert@twinsun.com>
7152
7153 * tests/action.at, tests/calc.at, tests/conflicts.at,
7154 tests/cxx-type.at, tests/headers.at, tests/input.at,
7155 tests/regression.at, tests/synclines.at, tests/torture.at:
7156 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
7157 so that the tests still work even if POSIXLY_CORRECT is set.
7158 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
7159
7160 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
7161 for portability to K&R hosts. Fix typo: signed char is guaranteed
7162 only to 127, not to 128.
7163 * data/glr.c (yysigned_char): New type.
7164 * data/yacc.c (yysigned_char): Likewise.
7165 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
7166
7167 2002-10-13 Paul Eggert <eggert@twinsun.com>
7168
7169 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
7170 true due to limited range of data type" warning from GCC.
7171
7172 * data/c.m4 (b4_token_defines): Protect against double-inclusion
7173 by wrapping enum yytokentype's definition inside #ifndef
7174 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
7175
7176 2002-10-13 Akim Demaille <akim@epita.fr>
7177
7178 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
7179 Un yy- yyrhs to avoid the name clash with the global YYRHS.
7180
7181 2002-10-13 Akim Demaille <akim@epita.fr>
7182
7183 * Makefile.maint: Update from Autoconf 2.54.
7184 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
7185
7186 2002-10-13 Akim Demaille <akim@epita.fr>
7187
7188 * src/print.c (print_state): Separate the list of solved conflicts
7189 from the other items.
7190 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
7191
7192 2002-10-13 Akim Demaille <akim@epita.fr>
7193
7194 Let nondeterministic skeletons be usable with deterministic
7195 tables.
7196
7197 With the patch, GAWK compiled by GCC without -O2 passes its test
7198 suite using a GLR parser driven by LALR tables. It fails with -O2
7199 because `struct stat' gives two different answers on my machine:
7200 88 (definition of an auto var) and later 96 (memset on this var).
7201 Hence the stack is badly corrumpted. The headers inclusion is to
7202 blame: if I move the awk.h inclusion before GLR's system header
7203 inclusion, the two struct stat have the same size.
7204
7205 * src/tables.c (pack_table): Always create conflict_table.
7206 (token_actions): Always create conflict_list.
7207 * data/glr.c (YYFLAG): Remove, unused.
7208
7209 2002-10-13 Akim Demaille <akim@epita.fr>
7210
7211 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
7212 (O0FLAGS): New.
7213 (VALGRIND, GXX): New.
7214 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
7215 * tests/bison.in: Run $PREBISON a pre-command.
7216 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
7217 (maintainer-check-g++): New.
7218 * Makefile.am (maintainer-check): New.
7219
7220 2002-10-13 Akim Demaille <akim@epita.fr>
7221
7222 * data/glr.c: Formatting changes.
7223 Tweak some trace messages to match yacc.c's.
7224
7225 2002-10-13 Akim Demaille <akim@epita.fr>
7226
7227 GLR parsers sometimes raise parse errors instead of performing the
7228 default reduction.
7229 Reported by Charles-Henry de Boysson.
7230
7231 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
7232 check the length of the traces when %glr.
7233 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
7234 GLR's traces.
7235 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
7236 Test GLR parsers.
7237 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
7238 (yyltype): Remove the yy prefix from the member names.
7239 (yytable): Complete its comment.
7240 (yygetLRActions): Map error action number from YYTABLE from
7241 YYTABLE_NINF to 0.
7242 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
7243 (which was a bug: it should have been YYTABEL_NINF, and yet it was
7244 not satisfying as we could compare an YYACTION computed from
7245 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
7246 only value for error actions.
7247 (yyreportParseError): In verbose parse error messages, don't issue
7248 `error' in the list of expected tokens.
7249 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
7250 next action to perform to match glr.c's decoding.
7251 (yytable): Complete its comment.
7252
7253 2002-10-13 Paul Eggert <eggert@twinsun.com>
7254
7255 Fix problem reported by Henrik Grubbstroem in
7256 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
7257 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
7258 because the Bison parser reads the second action before reducing
7259 the first one.
7260 * src/scan-gram.l (rule_length): New static var.
7261 Use it to keep track of the rule length in the scanner, since
7262 we can't expect the parser to be in lock-step sync with the scanner.
7263 (handle_action_dollar, handle_action_at): Use this var.
7264 * tests/actions.at (Exotic Dollars): Test for the problem.
7265
7266 2002-10-12 Paul Eggert <eggert@twinsun.com>
7267
7268 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
7269 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
7270 Include <sys/time.h> when checking for clock_t and struct tms.
7271 Use same include order as source.
7272 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
7273 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
7274
7275 * lib/timevar.c: Update copyright date and clarify comments.
7276 (get_time) [IN_GCC]: Keep the GCC version for reference.
7277
7278 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
7279 GCC version as of today, then merge Bison's changes.
7280 Change "GCC" to "Bison" in copyright notice. timevar.def's
7281 author is Akim, so change that too.
7282
7283 * src/reader.c (grammar_current_rule_check):
7284 Don't worry about the default action if $$ is untyped.
7285 Prevents bogus warnings reported by Jim Gifford in
7286 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
7287
7288 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
7289 * data/glr.c, data/lalr1.cc, data/yacc.c:
7290 Output token definitions before the first part of user declarations.
7291 Fixes compatibility problem reported by Jim Gifford for kbd in
7292 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
7293
7294 2002-10-11 Paul Eggert <eggert@twinsun.com>
7295
7296 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
7297 (yyparse): here. This undoes some of the 2002-07-25 change.
7298 Compatibility problem reported by Ralf S. Engelschall with
7299 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
7300
7301 2002-10-11 Akim Demaille <akim@epita.fr>
7302
7303 * tests/regression.at Characters Escapes): New.
7304 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
7305 characters.
7306 Reported by Jan Nieuwenhuizen.
7307
7308 2002-10-11 Akim Demaille <akim@epita.fr>

7312 2002-10-10 Paul Eggert <eggert@twinsun.com>
7313
7314 Portability fixes for bitsets; this also avoids several GCC
7315 warnings.
7316
7317 * lib/abitset.c: Include <stddef.h>, for offsetof.
7318 * lib/lbitset.c: Likewise.
7319
7320 * lib/abitset.c (abitset_bytes): Return a size that is aligned
7321 properly for vectors of objects. Do not assume that adding a
7322 header size to a multiple of a word size yields a value that is
7323 properly aligned for the whole union.
7324 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7325
7326 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
7327 unique names for structures.
7328 * lib/ebitset.c (ebitset_bytes): Likewise.
7329 * lib/lbitset.c (lbitset_bytes): Likewise.
7330
7331 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
7332 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
7333 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
7334 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
7335 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
7336 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
7337 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
7338 to improve the type-checking that GCC can do.
7339 * lib/bitset.c (bitset_op4_cmp): Likewise.
7340 * lib/bitset_stats.c (bitset_stats_count,
7341 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
7342 bitset_stats_copy, bitset_stats_disjoint_p,
7343 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
7344 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
7345 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
7346 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
7347 bitset_stats_and_or_cmp, bitset_stats_andn_or,
7348 bitset_stats_andn_or_cmp, bitset_stats_or_and,
7349 bitset_stats_or_and_cmp): Likewise.
7350 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
7351 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
7352 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
7353 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
7354
7355 * lib/abitset.h: Include bitset.h, not bbitset.h.
7356 * lib/ebitset.h: Likewise.
7357 * lib/lbitset.h: Likewise.
7358
7359 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
7360 All instances of parameters of type enum bitset_opts are now of
7361 type enum_bitset_opts, to conform to the C Standard, and similarly
7362 for enum_bitset_type.
7363 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
7364 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
7365
7366 Do not use "struct bitset_struct" to mean different things in
7367 different modules. Not only is this confusing, it violates
7368 the C Standard, which requires that structure types in different
7369 modules must be compatible if one is to be passed to the other.
7370 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
7371 All instances of "struct bitset_struct *" replaced with "bitset".
7372 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
7373 (union bitset_union, struct abitset_struct, struct ebitset_struct,
7374 struct lbitset_struct, struct bitset_stats_struct): New types.
7375 All uses of struct bitset_struct changed to union bitset_union,
7376 etc.
7377 * lib/abitset.c (struct abitset_struct, abitset,
7378 struct bitset_struct): Remove.
7379 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
7380 struct bitset_struct): Remove.
7381 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
7382 bitset_struct): Remove.
7383 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
7384 Likewise.
7385
7386 Do not call a function of type T using a call that assumes the
7387 function is of a different type U. Standard C requires that a
7388 function must be called with a type that is compatible with its
7389 definition.
7390 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
7391 New decls.
7392 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
7393 New functions.
7394 * lib/ebitset.c (PFV): Remove.
7395 * lib/lbitset.c (PFV): Likewise.
7396 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
7397 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
7398 decls.
7399 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
7400 (ebitset_vtable): Use them.
7401 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
7402 lbitset_xor): New functions.
7403 (lbitset_vtable): Use them.
7404
7405 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
7406 Declare.
7407
7408 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
7409 GCC warning.
7410 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
7411 Use offsetof, for simplicity.
7412
7413 2002-10-06 Paul Eggert <eggert@twinsun.com>
7414
7415 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
7416 the same width as int. This reapplies a hunk of the 2002-08-12 patch
7417 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
7418 which was inadvertently undone by the 2002-09-30 patch.
7419 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
7420 the same width as int.
7421
7422 2002-10-04 Paul Eggert <eggert@twinsun.com>
7423
7424 Version 1.50.
7425
7426 * configure.ac (AC_INIT), NEWS: Increment version number.
7427
7428 * doc/bison.texinfo: Minor spelling, grammar, and white space
7429 fixes.
7430 (Symbols): Mention that any negative value returned from yylex
7431 signifies end-of-input. Warn about negative chars. Mention
7432 the portable Standard C character set.
7433
7434 The GNU coding standard says CFLAGS and YFLAGS are reserved
7435 for the installer to set.
7436 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
7437 * src/Makefile.am (AM_CFLAGS): Likewise.
7438 (AM_YFLAGS): Renamed from YFLAGS.
7439
7440 Fix some MAX and MIN problems.
7441 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
7442 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
7443 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
7444 * src/reader.c (reader): Use it.
7445
7446 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
7447 POSIX 1003.1-2001 has removed fgrep.
7448
7449 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
7450
7451 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
7452 interpreted as signed.
7453 * lib/ebitset.c (ebitset_list): Fix bug.
7454
7455 2002-10-01 Paul Eggert <eggert@twinsun.com>
7456
7457 More fixes for 64-bit hosts and large bitsets.
7458
7459 * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
7460 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
7461 Use bitset_bindex, not int or unsigned int or size_t, to count bits.
7462 * lib/bbitset.h (struct bitset_vtable.size, struct bitset_vtable.count,
7463 struct bitset_vtable.list, struct bitset_vtable.list_reverse,
7464 bitset_count_, bitset_next, bitset_prev, bitset_first, bitset_last,
7465 bitset_count_): Likewise.
7466 * lib/bitset.h (bitset_iterator.num, bitset_iterator.i,
7467 bitset_first, bitset_last): Likewise.
7468 * lib/bitset_stats.c (bitset_stats_size, bitset_stats_list,

7480 Likewise.
7481
7482 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
7483 Use size_t, not unsigned int, to count bytes.
7484 * lib/abitset.h (abitset_bytes): Likewise.
7485 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):
7486 Likewise.

7500 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
7501 abitset_or_and, abitset_or_and_cmp):
7502 Use bitset_windex instead of unsigned int.
7503 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
7504 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,

7521 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
7522 to BITSET_WINDEX_MAX.
7523
7524 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
7525 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

7625
7626 * doc/bison.texinfo (Conditions): Make explicit that the GPL
7627 exception applies only to yacc.c. This is a modification of a
7628 patch originally suggested by Akim Demaille.
7629
7630 2002-09-06 Akim Demaille <akim@epita.fr>
7631

7639
7640 2002-09-04 Jim Meyering <jim@meyering.net>

7642 * data/yacc.c: Guard the declaration of yytoknum also with
7643 `#ifdef YYPRINT', so it is declared only when used.

7660
7661 * Makefile.am (SUBDIRS): Remove intl.

7677 functions are not portable. Do not assume size_t is the
7678 same width as int.
7679 (yypstates): Do not assume that ptrdiff_t is the same width
7680 as int, and similarly for yyposn and YYINDEX.
7681
7682 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
7683
7684 * lib/Makefile.am (INCLUDES): Do not include from the intl
7685 directory, which has been removed.
7686 * src/Makefile.am (INCLUDES): Likewise.

7719 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
7720
7721 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
7722 PROTOTYPES to check for prototypes, and "defined __STDC__" to
7723 check for void *.
7724
7725 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
7726 size_t; the old version tried to do this but casted improperly.
7727 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
7728 (bitset_test): Now returns int, not unsigned long.
7729
7730 * lib/bitset_stats.c: Include "gettext.h".
7731 (_): New macro.
7732 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
7733 name locals "index", as it generates unnecessary warnings on some
7734 hosts that have an "index" function.

7737 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

7751 glibc21.m4, isc-posix.m4 lcmessage.m4, stage.m4.
7752 * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.

7758 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
7759 lib/timevar.c.
7760 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
7761 manual recommends.
7762 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
7763
7764 * src/complain.c (strerror_r): Remove decl; not needed.
7765 (strerror): Use same pattern as ../lib/error.c.
7766
7767 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
7768
7769 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
7770
7771 * src/main.c (main): Cast result of bindtextdomain and textdomain
7772 to void, to avoid a GCC warning when --disable-nls is in effect.
7773
7774 * src/scan-gram.l: Use strings rather than escapes when possible,
7775 to minimize the number of warnings from xgettext.
7776 (handle_action_dollar, handle_action_at): Don't use isdigit,
7777 as it mishandles negative chars and it may not work as expected
7778 outside the C locale.
7779
7780 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
7781 this is a GCC extension and is not portable to other compilers.
7782
7783 * src/system.h (alloca): Use same pattern as ../lib/error.c.
7784 Do not include <ctype.h>; no longer needed.
7785 Do not include <malloc.h>; no longer needed (and generates
7786 warnings on OpenBSD 3.0).
7787
7788 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
7789 it's not portable.
7790
7791 * tests/regression.at: Do not use 'cc -c input.c -o input';
7792 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
7793
7794 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
7795 exit status as failure, not just exit status 1. Sun C exits
7796 with status 2 sometimes.
7797
7798 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
7799 Use it for the two large tests.
7800
7801 2002-08-02 Akim Demaille <akim@epita.fr>
7802
7803 * src/conflicts.c (conflicts_output): Don't output rules never
7804 reduced here, since anyway that computation doesn't work.

7811 * src/tables.c (action_row): Move the computation of rules never
7812 reduced to...
7813 (token_actions): here.

7815 that rules never reduced are computed.
7816 Call grammar_rules_never_reduced_report.
7817 * src/print.c (print_results): Report rules never reduced.
7818 * tests/conflicts.at, tests/reduce.at: Adjust.
7819
7820 2002-08-01 Akim Demaille <akim@epita.fr>
7821
7822 Instead of attaching lookaheads and duplicating the rules being
7823 reduced by a state, attach the lookaheads to the reductions.
7824
7825 * src/state.h (state_t): Remove the `lookaheads',
7826 `lookaheads_rule' member.
7827 (reductions_t): Add a `lookaheads' member.
7828 Use a regular array for the `rules'.

7830 to 0.

7839 (initialize_LA): this.
7840 (lalr_free): Adjust.
7841 * src/main.c (main): Don't free nullable and derives too early: it
7842 is used by --verbose.
7843 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
7844
7845 2002-08-01 Akim Demaille <akim@epita.fr>
7846
7847 * src/derives.h, src/derives.c (derives): A `rule_t***' instead of

7851 Adjust all dependencies.
7852 * src/nullable.c (set_nullable, free_nullable): Rename as...
7853 (nullable_compute, nullable_free): these.
7854 (rule_list_t): Store rule_t *, not rule_number_t.
7855 * src/state.c (state_rule_lookaheads_print): Directly compare rule
7856 pointers, instead of their numbers.
7857 * src/main.c (main): Call nullable_free, and derives_free earlier,
7858 as they were lo longer used.
7859
7860 2002-08-01 Akim Demaille <akim@epita.fr>
7861
7862 * lib/timevar.c (get_time): Include children time.

7864 state_t.
7865 * src/lalr.c (LA, LArule): Static.

7867 * src/main.c (main): Call it.
7868 * src/tables.c (pack_vector): Check whether loc is >= to the
7869 table_size, not >.
7870 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
7871 (tables_generate): do it, since that's also it which allocates
7872 them.
7873 Don't free LA and LArule, main does.
7874
7875 2002-07-31 Akim Demaille <akim@epita.fr>

7911 * src/getargs.h, src/getargs.c: Support trace_time for
7912 --trace=time.
7913 * src/main.c (stage): Remove.
7914 (main): Replace `stage' invocations with timevar calls.
7915 * src/output.c: Insert pertinent timevar calls.
7916

7922 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
7923 (long_options, short_options): --trace/-T takes an optional
7924 argument.
7925 Change all the uses of trace_flag to reflect the new flags.
7926 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
7927
7928 Strengthen `stage' portability.
7929
7930 * m4/stage.m4 (BISON_PREREQ_STAGE): New.
7931 * configure.in: Use it.
7932 Don't check for malloc.h and sys/times.h.
7933 * src/system.h: Include them when appropriate.
7934 * src/main.c (stage): Compile only when mallinfo, struct mallinfo,

7960 by conflicts.
7961
7962 * src/LR0.c (save_reductions): Don't make the final state too
7963 different: save its reduction (accept) instead of having a state
7964 without any action (no shift or goto, no reduce).
7965 Note: the final state is now a ``regular'' state, i.e., the
7966 parsers now contain `reduce 0' as default reduction.
7967 Nevertheless, since they decide to `accept' when yystate =
7968 final_state, they still will not reduce rule 0.
7969 * src/print.c (print_actions, print_reduction): Adjust.
7970 * src/output.c (action_row): Track reduced rules.

8011 2002-07-26 Akim Demaille <akim@epita.fr>
8012
8013 * src/reader.h, src/reader.c (gram_error): ... can't get
8014 yycontrol without making too strong assumptions on the parser
8015 itself.
8016 * src/output.c (prepare_tokens): Use the real 0th value of
8017 token_translations instead of `0'.
8018 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
8019 visible here.
8020 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
8021 for the time being: %locations ought to provide it to yyerror.
8022
8023 2002-07-25 Akim Demaille <akim@epita.fr>
8024
8025 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

8034 * src/nullable.c, src/output.c, src/print.c, src/reader.c
8035 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
8036 Iterate from 0 to nrules.
8037 Use rule_number_as_item_number and item_number_as_rule_number.
8038 Adjust to `derive' now containing possibly 0.
8039 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
8040 Handle the `- 1' part in rule numbers from/to item numbers.

9667 2002-04-22 Akim Demaille <akim@epita.fr>
9668
9669 * data/bison.simple (yyr1): Its type is that of a token number.
9670 * data/bison.c++ (r1_): Likewise.
9671 * tests/regression.at (Web2c Actions): Adjust.
9672
9673 2002-04-22 Akim Demaille <akim@epita.fr>
9674
9675 * src/reader.c (token_translations_init): 256 is now the default
9676 value for the error token, i.e., it will be assigned another
9677 number if the user assigned 256 to one of her tokens.
9678 (reader): Don't force 256 to error.
9679 * doc/bison.texinfo (Symbols): Adjust.
9680 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
9681 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
9682 etc. instead of 10, 20, 30 (which was used to `jump' over error
9683 (256) and undefined (2)).
9684
9685 2002-04-22 Akim Demaille <akim@epita.fr>
9686
9687 Propagate more token_number_t.
9688
9689 * src/gram.h (token_number_as_item_number)
9690 (item_number_as_token_number): New.
9691 * src/output.c (GENERATE_OUTPUT_TABLE): New.
9692 Use it to create output_item_number_table and
9693 output_token_number_table.
9694 * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c,
9695 * src/lex.c, src/nullable.c, src/output.c, src/print.c,
9696 * src/print_graph.c, src/reader.c, src/reduce.c, src/state.h,
9697 * src/symtab.c, src/symtab.h: Use token_number_t instead of shorts.

9699 2002-04-22 Akim Demaille <akim@epita.fr>
9700
9701 * src/output.h, src/output.c (get_lines_number): Remove.
9702
9703 2002-04-19 Akim Demaille <akim@epita.fr>
9704
9705 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
9706 as Lex/Flex'.
9707 (Debugging): More details about enabling the debugging features.
9708 (Table of Symbols): Describe $$, $n, @$, and @n.
9709 Suggested by Tim Josling.
9710
9711 2002-04-19 Akim Demaille <akim@epita.fr>
9712
9713 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
9714
9715 2002-04-10 Akim Demaille <akim@epita.fr>
9716
9717 * src/system.h: Rely on HAVE_LIMITS_H.
9718 Suggested by Paul Eggert.
9719
9720 2002-04-09 Akim Demaille <akim@epita.fr>
9721
9722 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
9723 full stderr, and strip it according to the bison options, instead
9724 of composing the error message from different bits.
9725 This makes it easier to check for several error messages.
9726 Adjust all the invocations.
9727 Add an invocation exercising the error token.
9728 Add an invocation demonstrating a stupid error message.
9729 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
9730 Adjust the tests.
9731 Error message are for stderr, not stdout.
9732
9733 2002-04-09 Akim Demaille <akim@epita.fr>
9734
9735 * src/gram.h, src/gram.c (error_token_number): Remove, use
9736 errtoken->number.
9737 * src/reader.c (reader): Don't specify the user token number (2)
9738 for $undefined, as it uselessly prevents using it.
9739 * src/gram.h (token_number_t): Move to...
9740 * src/symtab.h: here.
9741 (state_t.number): Is a token_number_t.
9742 * src/print.c, src/reader.c: Use undeftoken->number instead of
9743 hard coded 2.
9744 (Even though this 2 is not the same as above: the number of the
9745 undeftoken remains being 2, it is its user token number which
9746 might not be 2).
9747 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
9748 `user_token_number_max'.
9749 Output `undef_token_number'.
9750 * data/bison.simple, data/bison.c++: Use them.
9751 Be sure to map invalid yylex return values to
9752 `undef_token_number'. This saves us from gratuitous SEGV.
9753
9754 * tests/conflicts.at (Solved SR Conflicts)
9755 (Unresolved SR Conflicts): Adjust.
9756 * tests/regression.at (Web2c Actions): Adjust.
9757

9759
9760 * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
9761 Adding #line.
9762 Remove the duplicate `typedefs'.
9763 (RhsNumberType): Fix the declaration and various other typos.
9764 Use __ofile__.
9765 * data/bison.simple: Use __ofile__.
9766 * src/scan-skel.l: Handle __ofile__.

9769
9770 * src/gram.h (item_number_t): New, the type of item numbers in
9771 RITEM. Note that it must be able to code symbol numbers as
9772 positive number, and the negation of rule numbers as negative
9773 numbers.
9774 Adjust all dependencies (pretty many).
9775 * src/reduce.c (rule): Remove this `short *' pointer: use
9776 item_number_t.
9777 * src/system.h (MINSHORT, MAXSHORT): Remove.
9778 Include `limits.h'.
9779 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
9780 (shortcpy): Remove.
9781 (MAXTABLE): Move to...
9782 * src/output.c (MAXTABLE): here.
9783 (prepare_rules): Use output_int_table to output rhs.

9785 * tests/torture.at (Big triangle): Move the limit from 254 to
9786 500.
9787 * tests/regression.at (Web2c Actions): Ajust.
9788
9789 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
9790 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
9791 passes, but produces negative #line number, once fixed, GCC is
9792 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
9793 C), it passes.
9794 * src/state.h (state_h): Code input lines on ints, not shorts.
9795
9796 2002-04-08 Akim Demaille <akim@epita.fr>
9797
9798 * src/reduce.c (reduce_grammar): First reduce the nonterminals,

9811 New.
9812 Use them to define yy_token_number_type/TokenNumberType.
9813 Use this type for yytranslate.

9815 253.
9816 * tests/regression.at (Web2c Actions): Adjust.

9823
9824 2002-04-07 Akim Demaille <akim@epita.fr>
9825
9826 * src/gram.h, src/gram.c (nitems): Remove, it is an alias of
9827 nritems.
9828 Adjust dependencies.

9892
9893 2002-04-07 Akim Demaille <akim@epita.fr>

9921
9922 2002-04-07 Akim Demaille <akim@epita.fr>

9924 Be sure never to walk through RITEMS, but use only data related to
9925 the rules themselves. RITEMS should be banished.
9926
9927 * src/output.c (output_token_translations): Rename as...
9928 (prepare_tokens): this.
9929 In addition to `translate', prepare the muscles `tname' and

9942

9948 new_state.
9949 * src/closure.c (closure): Now that the initial state has its
9950 items properly set, there is no need for a special case when
9951 creating `ruleset'.
9952
9953 As a result, now the rule 0, reducing to $axiom, is visible in the
9954 outputs. Adjust the test suite.

9992 2002-04-07 Akim Demaille <akim@epita.fr>
9993
9994 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
9995 lacking `+ 1' to nrules, Bison reported as useless a token if it
9996 was used solely to set the precedence of the last rule...
9997
9998 2002-04-07 Akim Demaille <akim@epita.fr>
9999
10000 * data/bison.c++, data/bison.simple: Don't output the current file
10001 name in #line, to avoid useless diffs between two identical
10002 outputs under different names.

10005

10021 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
10022 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
10023 RHS, instead of being an index in RITEMS.

10291
10292 2002-02-14 Paul Eggert <eggert@twinsun.com>
10293
10294 Remove the support for C++ namespace cleanliness; it was
10295 causing more problems than it was curing, since it didn't work
10296 properly on some nonstandard C++ compilers. This can wait
10297 for a proper C++ parser.
10298
10299 * NEWS: Document this.
10300 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention

10342 more consistent when naming methods and variables. Put preprocessor
10343 directives around tables only needed for debugging.
10344
10345 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10346
10347 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

10373 More is certainly needed.
10374

10387 (token_definitions_output): No longer keeps track of the output
10388 line number, hence remove the second argument.
10389 (guards_output): Check against the guard member of a rule, not the
10390 action member.
10391 Adjust callers.
10392 (output_skeleton): Don't look for the skeleton location, let m4 do
10393 that.
10394 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
10395 file will be used.
10396 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
10397 (prepare): Given that for the time being changesyntax is not
10398 usable in M4, rename the muscles using `-' to `_'.
10399 Define `defines_flag', `output_parser_name' and `output_header_name'.
10400 * src/output.h (actions_output, guards_output)
10401 (token_definitions_output): Adjust prototypes.
10402 * src/scan-skel.l: Instead of scanning the skeletons, it now
10403 processes the output of m4: `__oline__' and `#output'.

10405 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
10406 to date.

10429
10430 * src/bison.simple (YYSIZE_T): Do not define merely because
10431 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

10433
10434 2002-01-27 Akim Demaille <akim@epita.fr>
10435
10436 Fix `%nonassoc and eof'.
10437
10438 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
10439 which were not properly copied! Replace
10440 memcpy (res->errs, src->errs, src->nerrs);
10441 with
10442 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
10443 !!!
10444 * tests/regression.at (%nonassoc and eof): Adjust to newest
10445 Autotest: `.' is not in the PATH.
10446

10523 * src/parse-skel.y (string, string.1): New.
10524 (section.header): Use it.
10525 (section.yacc): Remove.
10526 (prefix): Remove too.
10527 * src/scan-skel.l: Adjust.
10528 * src/bison.simple, src/bison.hairy: Adjust.
10529
10530 2002-01-09 Akim Demaille <akim@epita.fr>
10531
10532 * configure.in (WERROR_CFLAGS): Compute it.
10533 * src/Makefile.am (CFLAGS): Pass it.
10534 * tests/atlocal.in (CFLAGS): Idem.
10535 * src/files.c: Fix a few warnings.
10536 (get_extension_index): Remove, unused.
10537
10538 2002-01-08 Akim Demaille <akim@epita.fr>
10539
10540 * src/getargs.c (AS_FILE_NAME): New.
10541 (getargs): Use it to convert DOSish file names.
10542 * src/files.c (base_name): Rename as full_base_name to avoid
10543 clashes with `base_name ()'.
10544 (filename_split): New.
10545 (compute_base_names): N-th rewrite, using filename_split.
10546
10547 2002-01-08 Akim Demaille <akim@epita.fr>
10548
10549 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
10550 New, stolen from the Fileutils 4.1.
10551 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
10552 * configure.in: Check for the presence of memrchr, and of its
10553 prototype.
10554
10555 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
10556
10557 * lib/hash.h (__P): Added definition for this macro.
10558 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
10559 BUILT_SOURCES, to ensure they are generated first.
10560 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
10561 %error-verbose to allow bootstrapping with bison 1.30x.
10562
10563 2002-01-06 Akim Demaille <akim@epita.fr>
10564
10565 * src/reader.c (parse_braces): Don't fetch the next char, the
10566 convention is to fetch on entry.
10567 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
10568 'switch' without a following semicolon.
10569 * tests/regression.at (braces parsing): New.
10570
10571 2002-01-06 Akim Demaille <akim@epita.fr>
10572
10573 Bison is dead wrong in its RR conflict reports.
10574
10575 * tests/torture.at (GNU Cim Grammar): New.
10576 * src/conflicts.c (count_rr_conflicts): Fix.
10577
10578 2002-01-06 Akim Demaille <akim@epita.fr>
10579
10580 Creating package.m4 from configure.ac causes too many problems.
10581
10582 * tests/Makefile.am (package.m4): Create it by hand,
10583 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
10584
10585 2002-01-06 Akim Demaille <akim@epita.fr>
10586
10587 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
10588 skeleton.h.
10589
10590 2002-01-04 Paul Eggert <eggert@twinsun.com>
10591
10592 * doc/bison.texinfo (Debugging):
10593 Remove YYSTDERR; it's no longer defined or used.
10594 Also, s/cstdio.h/cstdio/.
10595
10596 2002-01-03 Akim Demaille <akim@epita.fr>
10597
10598 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
10599
10600 2002-01-03 Akim Demaille <akim@epita.fr>
10601
10602 * src/parse-skel.y (process_skeleton): Don't bind the parser's
10603 tracing code to --trace, wait for a better --trace option, with
10604 args.
10605
10606 2002-01-03 Akim Demaille <akim@epita.fr>
10607
10608 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
10609 The ISO C++ standard is extremely clear about it: stderr is
10610 considered a macro, not a regular symbol (see table 94 `Header
10611 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
10612 Therefore std:: does not apply to it. It still does with fprintf.
10613 Also, s/cstdio.h/cstdio/.
10614
10615 2002-01-03 Akim Demaille <akim@epita.fr>
10616
10617 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
10618 for non system headers.
10619
10620 2002-01-02 Akim Demaille <akim@epita.fr>
10621
10622 Equip the skeleton chain with location tracking, runtime trace,
10623 pure parser and scanner.
10624
10625 * src/parse-skel.y: Request a pure parser, locations, and prefix
10626 renaming.
10627 (%union): Having several members with the same type does not help
10628 type mismatches, simplify.
10629 (YYPRINT, yyprint): New.
10630 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
10631 (skel_error): this.
10632 Handle locations.
10633 * src/scan-skel.l: Adjust to these changes.
10634 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
10635 (LOCATION_PRINT, skel_control_t): New.
10636
10637 2001-12-30 Akim Demaille <akim@epita.fr>
10638
10639 * src/parse-skel.y: Get rid of the shift/reduce conflict:
10640 replace `gb' with BLANKS.
10641 * src/scan-skel.l: Adjust.
10642
10643 2001-12-30 Akim Demaille <akim@epita.fr>
10644
10645 * src/system.h: We don't need nor want bcopy.
10646 Throw away MS-DOS crap: we don't need getpid.
10647 * configure.in: We don't need strndup. It was even causing
10648 problems: because Flex includes the headers *before* us,
10649 _GNU_SOURCE is not defined by config.h, and therefore strndup was
10650 not visible.
10651 * lib/xstrndup.c: New.
10652 * src/scan-skel.l: Use it.
10653 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
10654 * src/parse-skel.y: Use %directives instead of #defines.
10655
10656 2001-12-30 Akim Demaille <akim@epita.fr>
10657
10658 * src/skeleton.h: New.
10659 * src/output.c (output_parser, output_master_parser): Remove, dead
10660 code.
10661 * src/output.h (get_lines_number, actions_output, guards_output)
10662 (token_definitions_output): Prototype them.
10663 * src/parse-skel.y: Add the license notice.
10664 Include output.h and skeleton.h.
10665 (process_skeleton): Returns void, and takes a single parameter.
10666 * src/scan-skel.l: Add the license notice.
10667 Include skeleton.h.
10668 Don't use %option yylineno: it seems that then Flex imagines
10669 REJECT has been used, and therefore it won't reallocate its
10670 buffers (which makes no other sense to me than a bug). It results
10671 in warnings for `unused: yy_flex_realloc'.
10672
10673 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
10674
10675 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10676 (MUSCLE_INSERT_PREFIX): ...to there.
10677 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10678 (MUSCLE_INSERT_PREFIX): Move from here...
10679
10680 * src/bison.hairy: Add a section directive. Put braces around muscle
10681 names. This parser skeleton is still broken, but Bison should not
10682 choke on a bad muscle 'syntax'.
10683 * src/bison.simple: Add a section directive. Put braces around muscle
10684 names.
10685
10686 * src/files.h (strsuffix, stringappend): Add declarations.
10687 (tab_extension): Add declaration.
10688 (short_base_name): Add declaration.
10689
10690 * src/files.c (strsuffix, stringappend): No longer static. These
10691 functions are used in the skeleton parser.
10692 (tab_extension): New.
10693 (compute_base_names): Use the computations done in this function
10694 to guess if the generated parsers should have '.tab' in their
10695 names.
10696 (short_base_name): No longer static.
10697
10698 * src/output.c (output_skeleton): New.
10699 (output): Disable call to output_master_parser, and give a try to
10700 a new skeleton handling system.
10701 (guards_output, actions_output): No longer static.
10702 (token_definitions_output, get_lines_number): No longer static.
10703
10704 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
10705
10706 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
10707 parse-skel.y.
10708
10709 * src/parse-skel.y: New file.
10710 * src/scan-skel.l: New file.
10711
10712 2001-12-29 Akim Demaille <akim@epita.fr>
10713
10714 %name-prefix is broken.
10715
10716 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
10717 Adjust all dependencies.
10718 * tests/headers.at (export YYLTYPE): Strengthen this test: use
10719 %name-prefix.
10720
10721 Renaming yylval but not yylloc is not consistent. Now we do.
10722
10723 * src/bison.simple: Prefix yylloc if used.
10724 * doc/bison.texinfo (Decl Summary): Document that.
10725
10726 2001-12-29 Akim Demaille <akim@epita.fr>
10727
10728 * doc/bison.texinfo: Promote `%long-directive' over
10729 `%long_directive'.
10730 Remove all references to fixed-output-files, yacc is enough.
10731
10732 2001-12-29 Akim Demaille <akim@epita.fr>
10733
10734 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
10735 user prologue. These are defaults.
10736 * tests/actions.at (Mid-rule actions): Make sure the user can
10737 define YYDEBUG and YYERROR_VERBOSE.
10738
10739 2001-12-29 Akim Demaille <akim@epita.fr>
10740
10741 * src/output.c (header_output): Don't forget to export YYLTYPE and
10742 yylloc.
10743 * tests/headers.at (export YYLTYPE): New, make sure it does.
10744 * tests/regression.at (%union and --defines, Invalid CPP headers):
10745 Move to...
10746 * tests/headers.at: here.
10747
10748 2001-12-29 Akim Demaille <akim@epita.fr>
10749
10750 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
10751
10752 2001-12-29 Akim Demaille <akim@epita.fr>
10753
10754 * tests/actions.at (Mid-rule actions): Output on a single line
10755 instead of several.
10756
10757 2001-12-29 Akim Demaille <akim@epita.fr>
10758
10759 * doc/bison.texinfo: Formatting changes.
10760
10761 2001-12-29 Akim Demaille <akim@epita.fr>
10762
10763 Don't store the token defs in a muscle, just be ready to output it
10764 on command. Now possible via `symbols'. Fixes a memory leak.
10765
10766 * src/output.c (token_definitions_output): New.
10767 (output_parser, header_output): Use it.
10768 * src/reader.c (symbols_save): Remove.
10769
10770 2001-12-29 Akim Demaille <akim@epita.fr>
10771
10772 * src/bison.simple: Do not provide a default for YYSTYPE and
10773 YYLTYPE before the user's prologue. Otherwise it's hardly... a
10774 default.
10775
10776 2001-12-29 Akim Demaille <akim@epita.fr>
10777
10778 Mid-rule actions are simply... ignored!
10779
10780 * src/reader.c (readgram): Be sure to attach mid-rule actions to
10781 the empty-rule associated to the dummy symbol, not to the host
10782 rule.
10783 * tests/actions.at (Mid-rule actions): New.
10784
10785 2001-12-29 Akim Demaille <akim@epita.fr>
10786
10787 Memory leak.
10788
10789 * src/reader.c (reader): Free grammar.
10790
10791 2001-12-29 Akim Demaille <akim@epita.fr>
10792
10793 Memory leak.
10794
10795 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
10796 since it allocates it for each state, although only one is needed.
10797 (allocate_storage): Do it here.
10798
10799 2001-12-29 Akim Demaille <akim@epita.fr>
10800
10801 * src/options.h, src/options.c (create_long_option_table): Rename
10802 as...
10803 (long_option_table_new): this, with a clearer prototype.
10804 (percent_table): Remove, unused,
10805 * src/getargs.c (getargs): Adjust.
10806
10807 2001-12-29 Akim Demaille <akim@epita.fr>
10808
10809 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
10810 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
10811 as states.
10812
10813 2001-12-29 Akim Demaille <akim@epita.fr>
10814
10815 * src/lalr.c (build_relations): Rename `states' as `states1'.
10816 Sorry, I don't understand exactly what it is, no better name...
10817
10818 2001-12-29 Akim Demaille <akim@epita.fr>
10819
10820 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
10821 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
10822 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
10823 as rules.
10824
10825 2001-12-29 Akim Demaille <akim@epita.fr>
10826
10827 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
10828 ago.
10829
10830 2001-12-29 Akim Demaille <akim@epita.fr>
10831
10832 * src/reader.c, src/reader.h (user_toknums): Remove.
10833 Adjust all users to use symbols[i]->user_token_number.
10834
10835 2001-12-29 Akim Demaille <akim@epita.fr>
10836
10837 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
10838 Adjust all users to use symbols[i]->prec or ->assoc.
10839
10840 2001-12-29 Akim Demaille <akim@epita.fr>
10841
10842 * src/reader.c, src/reader.h (tags): Remove.
10843 Adjust all users to use symbols[i]->tag.
10844
10845 2001-12-29 Akim Demaille <akim@epita.fr>
10846
10847 * src/gram.h, src/gram.c (symbols): New, similar to state_table
10848 and rule_table.
10849 * src/reader.c (packsymbols): Fill this table.
10850 Drop sprec.
10851 * src/conflicts.c (resolve_sr_conflict): Adjust.
10852 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
10853 single table.
10854 Use symbols[i]->tag instead of tags[i].
10855
10856 2001-12-29 Akim Demaille <akim@epita.fr>
10857
10858 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
10859 In addition, put a comment in there, to replace...
10860 * tests/regression.at (%union and C comments): Remove.
10861
10862 2001-12-29 Akim Demaille <akim@epita.fr>
10863
10864 * tests/regression.at (Web2c Actions): Blindly move the actual
10865 output as expected output. The contents *seem* right to me, but I
10866 can't pretend reading perfectly parser tables... Nonetheless, all
10867 the other tests pass correctly, the table look OK, even though the
10868 presence of `$axiom' is to be noted: AFAICS it is useless (but
10869 harmless).
10870
10871 2001-12-29 Akim Demaille <akim@epita.fr>
10872
10873 * src/reader.c (readgram): Don't add the rule 0 if there were no
10874 rules read. In other words, add it _after_ having performed
10875 grammar sanity checks.
10876 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
10877
10878 2001-12-29 Akim Demaille <akim@epita.fr>
10879
10880 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
10881 visible, and some states have now a different number.
10882
10883 2001-12-29 Akim Demaille <akim@epita.fr>
10884
10885 * src/reader.c (readgram): Bind the initial rule's lineno to that
10886 of the first rule.
10887 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
10888 (Solved SR Conflicts): Adjust rule 0's line number.
10889
10890 2001-12-29 Akim Demaille <akim@epita.fr>
10891
10892 Fix the `GAWK Grammar' failure.
10893
10894 * src/LR0.c (final_state): Initialize to -1 so that we do compute
10895 the reductions of the first state which was mistakenly confused
10896 with the final state because precisely final_state was initialized
10897 to 0.
10898 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
10899 now noticed by Bison.
10900 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
10901 have a reduction on $default.
10902
10903 2001-12-29 Akim Demaille <akim@epita.fr>
10904
10905 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
10906 rule line numbers.
10907 * src/closure.c (print_closure): Likewise.
10908 * src/derives.c (print_derives): Likewise.
10909 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
10910 now.
10911
10912 2001-12-29 Akim Demaille <akim@epita.fr>
10913
10914 * src/lalr.c (lookaheads_print): New.
10915 (lalr): Call it when --trace-flag.
10916 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
10917 are dumped.
10918
10919 2001-12-29 Akim Demaille <akim@epita.fr>
10920
10921 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
10922 when walking through ritem, even via rule->rhs.
10923 * src/reduce.c (dump_grammar, useful_production, reduce_output)
10924 (useful_production, useless_nonterminals): Likewise.
10925 (reduce_grammar_tables): Likewise, plus update nritems.
10926 * src/nullable.c (set_nullable): Likewise.
10927 * src/lalr.c (build_relations): Likewise.
10928 * tests/sets.at (Nullable): Adjust.
10929 Fortunately, now, the $axiom is no longer nullable.
10930
10931 2001-12-29 Akim Demaille <akim@epita.fr>
10932
10933 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
10934 the 0-sentinel.
10935 * src/gram.c (ritem_longest_rhs): Likewise.
10936 * src/reduce.c (nonterminals_reduce): Likewise.
10937 * src/print_graph.c (print_graph): Likewise.
10938 * src/output.c (output_rule_data): Likewise.
10939 * src/nullable.c (set_nullable): Likewise.
10940
10941 2001-12-29 Akim Demaille <akim@epita.fr>
10942
10943 * src/output.c: Comment changes.
10944
10945 2001-12-27 Paul Eggert <eggert@twinsun.com>
10946
10947 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
10948 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
10949 Sparc, as they were causing more porting problems than the
10950 (minor) performance improvement was worth.
10951
10952 Also, catch up with 1.31's YYSTD.
10953
10954 2001-12-27 Akim Demaille <akim@epita.fr>
10955
10956 * src/output.c (output_gram): Rely on nritems, not the
10957 0-sentinel. See below.
10958 Use -1 as separator, not 0.
10959 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
10960 Rely on -1 as separator in yyrhs, instead of 0.
10961 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
10962 twice `Now at end of input', therefore there are two lines less to
10963 expect.
10964
10965 2001-12-27 Akim Demaille <akim@epita.fr>
10966
10967 * tests/regression.at (Unresolved SR Conflicts):
10968 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
10969 below.
10970
10971 2001-12-27 Akim Demaille <akim@epita.fr>
10972
10973 * src/LR0.c (new_state): Recognize the final state by the fact it
10974 is reached by eoftoken.
10975 (insert_start_shifting_state, insert_eof_shifting_state)
10976 (insert_accepting_state, augment_automaton): Remove, since now
10977 these states are automatically computed from the initial state.
10978 (generate_states): Adjust.
10979 * src/print.c: When reporting a rule number to the user, substract
10980 1, so that the axiom rule is rule 0, and the first user rule is 1.
10981 * src/reduce.c: Likewise.
10982 * src/print_graph.c (print_core): For the time being, just as for
10983 the report, depend upon --trace-flags to dump the full set of
10984 items.
10985 * src/reader.c (readgram): Once the grammar read, insert the rule
10986 0: `$axiom: START-SYMBOL $'.
10987 * tests/set.at: Adjust: rule 0 is now displayed, and since the
10988 number of the states has changed (the final state is no longer
10989 necessarily the last), catch up.
10990
10991 2001-12-27 Akim Demaille <akim@epita.fr>
10992
10993 Try to make the use of the eoftoken valid. Given that its value
10994 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
10995 is used instead of > 0 where appropriate, (ii), depend upon nritems
10996 instead of the 0-sentinel.
10997
10998 * src/gram.h, src/gram.c (nritems): New.
10999 Expected to be duplication of nitems, but for the time being...
11000 * src/reader.c (packgram): Assert nritems and nitems are equal.
11001 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
11002 * src/closure.c (print_closure, print_fderives): Likewise.
11003 * src/gram.c (ritem_print): Likewise.
11004 * src/print.c (print_core, print_grammar): Likewise.
11005 * src/print_graph.c: Likewise.
11006
11007 2001-12-27 Akim Demaille <akim@epita.fr>
11008
11009 * src/main.c (main): If there are complains after grammar
11010 reductions, then output the report anyway if requested, then die.
11011 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
11012 * src/reader.c (eoftoken): New.
11013 (parse_token_decl): If the token being defined has value `0', it
11014 is the eoftoken.
11015 (packsymbols): No longer hack `tags' to insert `$' by hand.
11016 Be sure to preserve the value of the eoftoken.
11017 (reader): Make sure eoftoken is defined.
11018 Initialize nsyms to 0: now eoftoken is created just like the others.
11019 * src/print.c (print_grammar): Don't special case the eof token.
11020 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
11021 lie anyway, albeit pleasant.
11022 * tests/calc.at: Exercise error messages with eoftoken.
11023 Change the grammar so that empty input is invalid.
11024 Adjust expectations.
11025 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
11026
11027 2001-12-27 Akim Demaille <akim@epita.fr>
11028
11029 * configure.in: Check the protos of strchr ans strspn.
11030 Replace strchr if needed.
11031 * src/system.h: Provide the protos of strchr, strspn and memchr if
11032 missing.
11033 * lib/strchr.c: New.
11034 * src/reader.c (symbols_save): Use strchr.
11035
11036 2001-12-27 Akim Demaille <akim@epita.fr>
11037
11038 * src/print.c, src/print_graph.c (escape): New.
11039 Use it to quote the TAGS outputs.
11040 * src/print_graph.c (print_state): Now errors are in red, and
11041 reductions in green.
11042 Prefer high to wide: output the state number on a line of its own.
11043
11044 2001-12-27 Akim Demaille <akim@epita.fr>
11045
11046 * src/state.h, src/state.c (reductions_new): New.
11047 * src/LR0.c (set_state_table): Let all the states have a
11048 `reductions', even if reduced to 0.
11049 (save_reductions): Adjust.
11050 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
11051 * src/print.c (print_reductions, print_actions): Adjust.
11052 * src/output.c (action_row): Adjust.
11053
11054 2001-12-27 Akim Demaille <akim@epita.fr>
11055
11056 * src/state.h, src/state.c (errs_new, errs_dup): New.
11057 * src/LR0.c (set_state_table): Let all the states have an errs,
11058 even if reduced to 0.
11059 * src/print.c (print_errs, print_reductions): Adjust.
11060 * src/output.c (output_actions, action_row): Adjust.
11061 * src/conflicts.c (resolve_sr_conflict): Adjust.
11062
11063 2001-12-27 Akim Demaille <akim@epita.fr>
11064
11065 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
11066
11067 2001-12-27 Akim Demaille <akim@epita.fr>
11068
11069 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
11070 * src/print.c: here.
11071 (lookaheadset, shiftset): New, used as additional storage by
11072 print_reductions.
11073 (print_results): Adjust.
11074 (print_shifts, print_gotos, print_errs): New, extracted from...
11075 (print_actions): here.
11076 * src/print_graph.c (print_actions): Remove dead code.
11077
11078 2001-12-27 Akim Demaille <akim@epita.fr>
11079
11080 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
11081 `$n' and `@n'.
11082
11083 2001-12-27 Akim Demaille <akim@epita.fr>
11084
11085 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
11086 (build_relations): Adjust.
11087
11088 2001-12-27 Akim Demaille <akim@epita.fr>
11089
11090 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
11091 duplication.
11092
11093 2001-12-27 Akim Demaille <akim@epita.fr>
11094
11095 * src/reader.c (packgram): Catch nitems overflows.
11096
11097 2001-12-27 Akim Demaille <akim@epita.fr>
11098
11099 * src/files.c, src/files.h (guard_obstack): Remove.
11100 * src/output.c (output): Adjust.
11101 * src/reader.c (parse_braces): New, factoring...
11102 (copy_action, copy_guard): these two which are renamed as...
11103 (parse_action, parse_guard): these.
11104 As a voluntary consequence, using braces around guards is now
11105 mandatory.
11106
11107 2001-12-27 Akim Demaille <akim@epita.fr>
11108
11109 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
11110 * src/reader.c (symbol_list): `guard' and `guard_line' are new
11111 members.
11112 (symbol_list_new): Adjust.
11113 (copy_action): action_line is the first line, not the last.
11114 (copy_guard): Just as for actions, store the `action' only, not
11115 the switch/case/break flesh.
11116 Don't parse the user action that might follow the guard, let...
11117 (readgram): do it, i.e., now, there can be an action after a
11118 guard.
11119 In other words the guard is just explicitly optional.
11120 (packgram): Adjust.
11121 * src/output.c (guards_output): New.
11122 (output_parser): Call it when needed.
11123 (output): Also free the guard and attrs obstacks.
11124 * src/files.c, src/files.h (obstack_save): Remove.
11125 (output_files): Remove.
11126 As a result, if one needs the former `.act' file, using an
11127 appropriate skeleton which requires actions and guards is now
11128 required.
11129 * src/main.c (main): Adjust.
11130 * tests/semantic.at: New.
11131 * tests/regression.at: Use `input.y' as input file name.
11132 Avoid 8+3 problems by requiring input.c when the test needs the
11133 parser.
11134
11135 2001-12-27 Akim Demaille <akim@epita.fr>
11136
11137 * src/reader.c (symbol_list_new): Be sure to initialize all the
11138 fields.
11139
11140 2001-12-27 Akim Demaille <akim@epita.fr>
11141
11142 All the hacks using a final pseudo state are now useless.
11143
11144 * src/LR0.c (set_state_table): state_table holds exactly nstates.
11145 * src/lalr.c (nLA): New.
11146 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
11147 instead of lookaheadsp from the pseudo state (nstate + 1).
11148
11149 2001-12-27 Akim Demaille <akim@epita.fr>
11150
11151 * src/output.c (action_row, token_actions): Use a state_t instead
11152 of a integer, and nlookaheads instead of the following state's
11153 lookaheadsp.
11154
11155 2001-12-27 Akim Demaille <akim@epita.fr>
11156
11157 * src/conflicts.c (log_resolution, flush_shift)
11158 (resolve_sr_conflict, set_conflicts, solve_conflicts)
11159 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
11160 (conflicts_print, print_reductions): Use a state_t instead of an
11161 integer when referring to a state.
11162 As much as possible, depend upon nlookaheads, instead of the
11163 `lookaheadsp' member of the following state (since lookaheads of
11164 successive states are successive, the difference between state n + 1
11165 and n served as the number of lookaheads for state n).
11166 * src/lalr.c (add_lookback_edge): Likewise.
11167 * src/print.c (print_core, print_actions, print_state)
11168 (print_results): Likewise.
11169 * src/print_graph.c (print_core, print_actions, print_state)
11170 (print_graph): Likewise.
11171 * src/conflicts.h: Adjust.
11172
11173 2001-12-27 Akim Demaille <akim@epita.fr>
11174
11175 * src/bison.hairy: Formatting/comment changes.
11176 ANSIfy.
11177 Remove `register' indications.
11178 Add plenty of `static'.
11179
11180 2001-12-27 Akim Demaille <akim@epita.fr>
11181
11182 * src/output.c (prepare): Drop the muscle `ntbase' which
11183 duplicates ntokens.
11184 * src/bison.simple: Formatting/comment changes.
11185 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
11186 is an undocumented synonym.
11187
11188 2001-12-22 Akim Demaille <akim@epita.fr>
11189
11190 * src/output.c (output_table_data): Change the prototype to use
11191 `int' for array ranges: some invocations do pass an int, not a
11192 short.
11193 Reported by Wayne Green.
11194
11195 2001-12-22 Akim Demaille <akim@epita.fr>
11196
11197 Some actions of web2c.y are improperly triggered.
11198 Reported by Mike Castle.
11199
11200 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
11201 * tests/regression.at (Web2c): Rename as...
11202 (Web2c Report): this.
11203 (Web2c Actions): New.
11204
11205 2001-12-22 Akim Demaille <akim@epita.fr>
11206
11207 Reductions in web2c.y are improperly reported.
11208 Reported by Mike Castle.
11209
11210 * src/conflicts.c (print_reductions): Fix.
11211 * tests/regression.at (Web2c): New.
11212
11213 2001-12-18 Akim Demaille <akim@epita.fr>
11214
11215 Some host fail on `assert (!"foo")', which expands to
11216 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
11217 Reported by Nelson Beebee.
11218
11219 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
11220 `#define it_succeeded 0' and `assert (it_succeeded)'.
11221
11222 2001-12-17 Marc Autret <autret_m@epita.fr>
11223
11224 * src/bison.simple: Don't hard code the skeleton line and filename.
11225 * src/output.c (output_parser): Rename 'line' as 'output_line'.
11226 New line counter 'skeleton_line' (skeleton-line muscle).
11227
11228 2001-12-17 Paul Eggert <eggert@twinsun.com>
11229
11230 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
11231 YYDEBUG must be defined to a nonzero value.
11232
11233 * src/bison.simple (yytname): Do not assume that the user defines
11234 YYDEBUG to a properly parenthesized expression.
11235
11236 2001-12-17 Akim Demaille <akim@epita.fr>
11237
11238 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
11239 nlookaheads is a new member.
11240 Adjust all users.
11241 * src/lalr.h (nlookaheads): Remove this orphan declaration.
11242 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
11243 state.
11244
11245 2001-12-17 Akim Demaille <akim@epita.fr>
11246
11247 * src/files.h, src/files.c (open_files, close_files): Remove.
11248 * src/main.c (main): Don't open/close files, nor invoke lex_free,
11249 let...
11250 * src/reader.c (reader): Do it.
11251
11252 2001-12-17 Akim Demaille <akim@epita.fr>
11253
11254 * src/conflicts.c (print_reductions): Formatting changes.
11255
11256 2001-12-17 Akim Demaille <akim@epita.fr>
11257
11258 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
11259 (flush_reduce): New.
11260 (resolve_sr_conflict): Adjust.
11261
11262 2001-12-17 Akim Demaille <akim@epita.fr>
11263
11264 * src/output.c (output_obstack): Be static and rename as...
11265 (format_obstack): this, to avoid any confusion with files.c's
11266 output_obstack.
11267 * src/reader.h (muscle_obstack): Move to...
11268 * src/output.h: here, since it's defined in output.c.
11269
11270 2001-12-17 Akim Demaille <akim@epita.fr>
11271
11272 * src/output.c (action_row, save_column, default_goto)
11273 (sort_actions, matching_state, pack_vector): Better variable
11274 locality.
11275
11276 2001-12-17 Akim Demaille <akim@epita.fr>
11277
11278 * src/output.c: Various formatting changes.
11279
11280 2001-12-17 Akim Demaille <akim@epita.fr>
11281
11282 * src/files.c (output_files): Free the output_obstack.
11283 * src/main.c (main): Call print and print_graph conditionally.
11284 * src/print.c (print): Work unconditionally.
11285 * src/print_graph.c (print_graph): Work unconditionally.
11286 * src/conflicts.c (log_resolution): Output only if verbose_flag.
11287
11288 2001-12-16 Marc Autret <autret_m@epita.fr>
11289
11290 * src/output.c (actions_output): Fix. When we use %no-lines,
11291 there is one less line per action.
11292
11293 2001-12-16 Marc Autret <autret_m@epita.fr>
11294
11295 * src/bison.simple: Remove a useless #line directive.
11296 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
11297 * src/output.c (get_lines_number): New.
11298 (output_parser): Adjust, now takes care about the lines of a
11299 output muscles.
11300 Fix line numbering.
11301 (actions_output): Computes the number of lines taken by actions.
11302 (output_master_parser): Insert new skeleton which is the name of
11303 the output parser file name.
11304
11305 2001-12-15 Marc Autret <autret_m@epita.fr>
11306
11307 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
11308
11309 2001-12-15 Marc Autret <autret_m@epita.fr>
11310
11311 * src/output.c (output_gram): Keep track of the hairy one.
11312
11313 2001-12-15 Akim Demaille <akim@epita.fr>
11314
11315 Make `make distcheck' work.
11316
11317 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
11318 system.h which uses libgettext.h.
11319
11320 2001-12-15 Akim Demaille <akim@epita.fr>
11321
11322 * src/nullable.c (set_nullable): Useless rules must be skipped,
11323 otherwise, since we range over their symbols, we might look at a
11324 nonterminal which no longer ``exists'', i.e., it is not counted in
11325 `nvars', hence we overflow our arrays.
11326
11327 2001-12-15 Akim Demaille <akim@epita.fr>
11328
11329 The header can also be produced directly, without any obstack!
11330 Yahoo!
11331
11332 * src/files.c, src/files.h (defines_obstack): Remove.
11333 (compute_header_macro): Global.
11334 (defines_obstack_save): Remove.
11335 * src/reader.c (parse_union_decl): No longer output to
11336 defines_obstack: its content can be found in the `stype' muscle
11337 anyway.
11338 (output_token_translations): Merge into...
11339 (symbols_output): this.
11340 Rename as...
11341 (symbols_save): this.
11342 (reader): Adjust.
11343 * src/output.c (header_output): New.
11344 (output): Call it.
11345
11346 2001-12-15 Akim Demaille <akim@epita.fr>
11347
11348 * src/reader.c (parse_union_decl): Instead of handling two obstack
11349 simultaneously, use one to define the `stype' muscle, and use the
11350 value of the latter to fill defines_obstack.
11351 (copy_comment): Remove.
11352 (copy_comment2): Work for a single obstack.
11353 Rename as...
11354 (copy_comment): this.
11355
11356 2001-12-15 Akim Demaille <akim@epita.fr>
11357
11358 * src/lex.c, src/lex.h (xgetc): No longer static.
11359 * src/reader.c (parse_union_decl): Revamp.
11360
11361 2001-12-15 Akim Demaille <akim@epita.fr>
11362
11363 Still making progress in separating Bison into (i) input, (ii)
11364 process, (iii) output: now we can directly output the parser file
11365 without using table_obstack at all.
11366
11367 * src/files.c, src/files.h (table_obstack): Bye bye.
11368 (parser_file_name): New.
11369 * src/files.c (compute_output_file_names): Compute it.
11370 * src/output.c (actions_output, output_parser)
11371 (output_master_parser): To a file instead of an obstack.
11372
11373 2001-12-15 Akim Demaille <akim@epita.fr>
11374
11375 Attach actions to rules, instead of pre-outputting them to
11376 actions_obstack.
11377
11378 * src/gram.h (rule_t): action and action_line are new members.
11379 * src/reader.c (symbol_list): Likewise.
11380 (copy_action): Save the actions within the rule.
11381 (packgram): Save them in rule_table.
11382 * src/output.c (actions_output): New.
11383 (output_parser): Use it on `%%actions'.
11384 (output_rule_data): Don't free rule_table.
11385 (output): Do it.
11386 (prepare): Don't save the `action' muscle.
11387 * src/bison.simple: s/%%action/%%actions/.
11388
11389 2001-12-15 Akim Demaille <akim@epita.fr>
11390
11391 * src/reader.c (copy_action): When --yacc, don't append a `;'
11392 to the user action: let it fail if lacking.
11393 Suggested by Arnold Robbins and Tom Tromey.
11394
11395 2001-12-14 Akim Demaille <akim@epita.fr>
11396
11397 * src/lex.c (literalchar): Simply return the char you decoded, non
11398 longer mess around with obstacks and int pointers.
11399 Adjust all callers.
11400
11401 2001-12-14 Akim Demaille <akim@epita.fr>
11402
11403 * src/lex.c (literalchar): Don't escape the special characters,
11404 just decode them, and keep them as char (before, eol was output as
11405 the 2 char string `\n' etc.).
11406 * src/output.c (output_rule_data): Use quotearg to output the
11407 token strings.
11408
11409 2001-12-13 Paul Eggert <eggert@twinsun.com>
11410
11411 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
11412 Do not infringe on the global user namespace when using C++.
11413 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
11414 All uses of `fprintf' and `stderr' changed.
11415
11416 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
11417
11418 2001-12-13 Akim Demaille <akim@epita.fr>
11419
11420 The computation of nullable is broken: it doesn't handle empty
11421 RHS's properly.
11422
11423 * tests/torture.at (GNU AWK Grammar): New.
11424 * tests/sets.at (Nullable): New.
11425 * src/nullable.c (set_nullable): Instead of blindly looping over
11426 `ritems', loop over the rules, and then over their rhs's.
11427
11428 Work around Autotest bugs.
11429
11430 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
11431 frame, because Autotest understand lines starting with a `+' as
11432 traces from the shell. Then, they are not processed properly.
11433 Admittedly an Autotest bug, but we don't have time to wait for
11434 Autotest to catch up.
11435 * tests/regression.at (Broken Closure): Adjust to the new table
11436 frames.
11437 Move to...
11438 * tests/sets.at: here.
11439
11440 2001-12-13 Akim Demaille <akim@epita.fr>
11441
11442 * src/closure.c (closure): Use nrules instead of playing tricks
11443 with BITS_PER_WORD.
11444
11445 2001-12-13 Akim Demaille <akim@epita.fr>
11446
11447 * src/print.c (print_actions): Output the handling of `$' as the
11448 traces do: shifting the token EOF. Before EOF was treated as a
11449 nonterminal.
11450 * tests/regression.at: Adjust some tests.
11451 * src/print_graph.c (print_core): Complete the set of items via
11452 closure. The next-to-final and final states are still unsatisfying,
11453 but that's to be addressed elsewhere.
11454 No longer output the rule numbers, but do output the state number.
11455 A single loop for the shifts + gotos is enough, but picked a
11456 distinct color for each.
11457 (print_graph): Initialize and finalize closure.
11458
11459 2001-12-13 Akim Demaille <akim@epita.fr>
11460
11461 * src/reader.c (readgram): Remove dead code, an strip useless
11462 braces.
11463 (get_type): Remove, unused.
11464
11465 2001-12-12 Akim Demaille <akim@epita.fr>
11466
11467 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
11468 on that of lib/error.c.
11469
11470 2001-12-12 Akim Demaille <akim@epita.fr>
11471
11472 Some hosts don't like `/' in includes.
11473
11474 * src/system.h: Include libgettext.h without qualifying the path.
11475 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
11476 $(top_srcdir).
11477
11478 2001-12-11 Marc Autret <autret_m@epita.fr>
11479
11480 * src/output.c (output_parser): Remove useless muscle.
11481
11482 2001-12-11 Marc Autret <autret_m@epita.fr>
11483
11484 * src/bison.simple: Remove #line just before %%epilogue. It
11485 is now handled in ...
11486 * src/reader.c (read_additionnal_code): Add the output of a
11487 #line for the epilogue.
11488
11489 2001-12-10 Marc Autret <autret_m@epita.fr>
11490
11491 * src/reader.c (copy_definition): Re-use CPP-outed code which
11492 replace precedent remove.
11493 * src/bison.simple: Remove #line before %%prologue because
11494 %%input-line is wrong at this time.
11495
11496 2001-12-10 Marc Autret <autret_m@epita.fr>
11497
11498 * src/reader.c (symbols_output): Clean up.
11499 * src/output.c (output_gram, output): Clean up.
11500
11501 2001-12-10 Akim Demaille <akim@epita.fr>
11502
11503 * src/lalr.c (initialize_lookaheads): New. Extracted from...
11504 * src/LR0.c (set_state_table): here.
11505 * src/lalr.c (lalr): Call it.
11506
11507 2001-12-10 Akim Demaille <akim@epita.fr>
11508
11509 * src/state.h (shifts): Remove the `number' member: shifts are
11510 attached to state, hence no longer need to be labelled with a
11511 state number.
11512
11513 2001-12-10 Akim Demaille <akim@epita.fr>
11514
11515 Now that states have a complete set of members, the linked list of
11516 shifts is useless: just fill directly the state's shifts member.
11517
11518 * src/state.h (shifts): Remove the `next' member.
11519 * src/LR0.c (first_state, last_state): Remove.
11520 Adjust the callers.
11521 (augment_automaton): Don't look for the shifts that must be added
11522 a shift on EOF: it is those of the state we looked for! But now,
11523 since shifts are attached, it is no longer needed to looking
11524 merely by its id: its number.
11525
11526 2001-12-10 Akim Demaille <akim@epita.fr>
11527
11528 * src/LR0.c (augment_automaton): Better variable locality.
11529 Remove an impossible branch: if there is a state corresponding to
11530 the start symbol being shifted, then there is shift for the start
11531 symbol from the initial state.
11532
11533 2001-12-10 Akim Demaille <akim@epita.fr>
11534
11535 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
11536 only when appropriate: when insert_start_shifting_state' is not
11537 invoked.
11538 * tests/regression.at (Rule Line Numbers): Adjust.
11539
11540 2001-12-10 Akim Demaille <akim@epita.fr>
11541
11542 * src/LR0.c (augment_automaton): Now that all states have shifts,
11543 merge the two cases addition shifts to the initial state.
11544
11545 2001-12-10 Akim Demaille <akim@epita.fr>
11546
11547 * src/lalr.c (set_state_table): Move to...
11548 * src/LR0.c: here.
11549 * src/lalr.c (lalr): Don't call it...
11550 * src/LR0.c (generate_states): do it.
11551 * src/LR0.h (first_state): Remove, only the table is used.
11552
11553 2001-12-10 Akim Demaille <akim@epita.fr>
11554
11555 * src/LR0.h (first_shift, first_reduction): Remove.
11556 * src/lalr.c: Don't use first_shift: find shifts through the
11557 states.
11558
11559 2001-12-10 Akim Demaille <akim@epita.fr>
11560
11561 * src/LR0.c: Attach shifts to states as soon as they are
11562 computed.
11563 * src/lalr.c (set_state_table): Instead of assigning shifts to
11564 state, just assert that the mapping was properly done.
11565
11566 2001-12-10 Akim Demaille <akim@epita.fr>
11567
11568 * src/LR0.c (insert_start_shift): Rename as...
11569 (insert_start_shifting_state): this.
11570 (insert_eof_shifting_state, insert_accepting_state): New.
11571 (augment_automaton): Adjust.
11572 Better locality of the variables.
11573 When looking if the start_symbol is shifted from the initial
11574 state, using `while (... symbol != start_symbol ...)' sounds
11575 better than `while (... symbol < start_symbol ...)': If fail
11576 to see how the order between symbols could be relevant!
11577
11578 2001-12-10 Akim Demaille <akim@epita.fr>
11579
11580 * src/getargs.h: Don't declare `spec_name_prefix' and
11581 `spec_file_prefix', declared by src/files.h.
11582 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
11583 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
11584 * src/output.c (prepare): Adjust.
11585 * src/reader.c (symbols_output): Likewise.
11586 * src/vmsgetargs.c: Vaguely adjust, but who cares?
11587
11588 2001-12-10 Akim Demaille <akim@epita.fr>
11589
11590 * src/muscle_tab.c (muscle_init): NULL is a better default than
11591 `"0"'.
11592
11593 2001-12-10 Akim Demaille <akim@epita.fr>
11594
11595 * src/reader.c (reader): Calling symbols_output once is enough.
11596
11597 2001-12-10 Akim Demaille <akim@epita.fr>
11598
11599 Now that states have a complete set of members, the linked list of
11600 reductions is useless: just fill directly the state's reductions
11601 member.
11602
11603 * src/state.h (struct reductions): Remove member `number' and
11604 `next'.
11605 * src/LR0.c (first_reduction, last_reduction): Remove.
11606 (save_reductions): Don't link the new reductions, store them in
11607 this_state.
11608 * src/lalr.c (set_state_table): No need to attach reductions to
11609 states, it's already done.
11610 * src/output.c (output_actions): No longer free the shifts, then
11611 the reductions, then the states: free all the states and their
11612 members.
11613
11614 2001-12-10 Akim Demaille <akim@epita.fr>
11615
11616 * src/options.c (OPTN, DRTV, BOTH): New.
11617 (option_table): Use them.
11618
11619 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
11620 the job of system.h.
11621 * src/options.c: Don't include stdio.h and xalloc.h for the same
11622 reasons.
11623
11624 2001-12-10 Akim Demaille <akim@epita.fr>
11625
11626 * src/output.c (output, prepare): Make sure the values of the
11627 muscles `action' and `prologue' are 0-terminated.
11628
11629 2001-12-10 Akim Demaille <akim@epita.fr>
11630
11631 Clean up GCC warnings.
11632
11633 * src/reader.c (copy_action): `buf' is not used.
11634 (parse_skel_decl): Be static.
11635 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
11636 * src/options.h (create_long_option_table): Have a real prototype.
11637 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
11638 (hash_delete_at): Return const void *.
11639 Adjust casts to preserve the const.
11640
11641 2001-12-10 Akim Demaille <akim@epita.fr>
11642
11643 * configure.in: Require 2.52g.
11644 M4 is not needed, but AUTOM4TE is.
11645 * m4/m4.m4: Remove.
11646 * tests/Makefile.am: Adjust.
11647
11648 2001-12-10 Akim Demaille <akim@epita.fr>
11649
11650 One structure for states is enough, even though theoretically
11651 there are LR(0) states and LALR(1) states.
11652
11653 * src/lalr.h (state_t): Remove.
11654 (state_table): Be state_t **, not state_t *.
11655 * src/state.h (core, CORE_ALLOC): Rename as...
11656 (state_t, STATE_ALLOC): this.
11657 Add the LALR(1) members: shifts, reductions, errs.
11658 * src/LR0.c (state_table): Rename as...
11659 (state_hash): this, to avoid name clashes with the global
11660 `state_table'.
11661 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
11662 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
11663
11664 2001-12-10 Akim Demaille <akim@epita.fr>
11665
11666 Bison dumps core on bash.y.
11667 Reported by Pascal Bart.
11668
11669 * src/warshall.c (bitmatrix_print): New.
11670 (TC): Use it.
11671 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
11672 j must be the outer loop.
11673 * tests/regression.at (Broken Closure): New.
11674
11675 2001-12-05 Akim Demaille <akim@epita.fr>
11676
11677 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
11678 its argument.
11679 Reported by Peter Hamorsky.
11680
11681 2001-12-05 Akim Demaille <akim@epita.fr>
11682
11683 * src/conflicts.c (err_table): Remove.
11684 (resolve_sr_conflict): Adjust.
11685 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
11686 Rename as...
11687 (state_t.reductions, state_t.shifts): this.
11688
11689 2001-12-05 Akim Demaille <akim@epita.fr>
11690
11691 * src/reduce.c (reduce_grammar_tables): No longer disable the
11692 removal of useless rules via CPP but via `if (0)', so that the
11693 compiler still check the code is valid.
11694 For instance, it should have noticed `rline' no longer exists: use
11695 the `line' member of rule_t.
11696 * src/gram.c (dummy, rline): Remove, unused.
11697
11698 2001-12-05 Akim Demaille <akim@epita.fr>
11699
11700 * src/output.c (pack_vector): Use assert, not berror.
11701 * src/main.c (berror): Remove, unused.
11702
11703 2001-12-05 Akim Demaille <akim@epita.fr>
11704
11705 New experimental feature: if --verbose --trace output all the
11706 items of a state, not only its kernel.
11707
11708 * src/print.c (print_core): If `trace_flag', then invoke closure
11709 before outputting the items of the state (print_core is no longer
11710 a correct name them).
11711 (print_results): Invoke new_closure/free_closure if needed.
11712
11713 2001-12-05 Akim Demaille <akim@epita.fr>
11714
11715 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
11716 * src/closure.c, src/closure.h (itemsetsize): Rename as...
11717 (nitemset): for consistency with the rest of the project.
11718
11719 2001-12-05 Akim Demaille <akim@epita.fr>
11720
11721 * src/closure.c (print_closure): Improve.
11722 (closure): Use it for printing input and output.
11723
11724 2001-12-05 Akim Demaille <akim@epita.fr>
11725
11726 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
11727 indexed by nonterminals.
11728
11729 2001-12-05 Akim Demaille <akim@epita.fr>
11730
11731 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
11732 what it was!).
11733 * src/warshall.h: Remove accidental duplication of the content.
11734
11735 2001-12-05 Akim Demaille <akim@epita.fr>
11736
11737 * src/closure.c (set_fderives): De-obfuscate.
11738
11739 2001-12-05 Akim Demaille <akim@epita.fr>
11740
11741 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
11742
11743 2001-12-05 Akim Demaille <akim@epita.fr>
11744
11745 * src/closure.c (set_firsts): De-obfuscate.
11746
11747 2001-12-05 Akim Demaille <akim@epita.fr>
11748
11749 * src/output.c (action_row): De-obfuscate
11750 using the good o' techniques: arrays not pointers, variable
11751 locality, BITISSET, RESETBIT etc.
11752
11753 2001-12-05 Akim Demaille <akim@epita.fr>
11754
11755 Pessimize the code to simplify it: from now on, all the states
11756 have a valid SHIFTS, which NSHIFTS is possibly 0.
11757
11758 * src/LR0.c (shifts_new): Be global and move to..
11759 * src/state.c, src/state.h: here.
11760 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
11761 * src/print_graph: Adjust.
11762
11763 2001-12-05 Akim Demaille <akim@epita.fr>
11764
11765 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
11766 * src/conflicts.c: Use it.
11767 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
11768 incorrectly ``simplified''.
11769
11770 2001-12-05 Akim Demaille <akim@epita.fr>
11771
11772 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
11773 using the good o' techniques: arrays not pointers, variable
11774 locality, BITISSET, RESETBIT etc.
11775
11776 2001-12-05 Akim Demaille <akim@epita.fr>
11777
11778 * src/state.h (SHIFT_SYMBOL): New.
11779 * src/conflicts.c: Use it to deobfuscate.
11780
11781 2001-12-05 Akim Demaille <akim@epita.fr>
11782
11783 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
11784 (print_reductions): De-obfuscate using the good o' techniques:
11785 arrays not pointers, variable locality, BITISSET.
11786
11787 2001-12-05 Akim Demaille <akim@epita.fr>
11788
11789 * src/conflicts.c (print_reductions): Arrays, not pointers.
11790 Use BITISSET.
11791
11792 2001-12-05 Akim Demaille <akim@epita.fr>
11793
11794 * src/conflicts.c (print_reductions): Pessimize, but clarify.
11795
11796 2001-12-05 Akim Demaille <akim@epita.fr>
11797
11798 * src/conflicts.c (print_reductions): Improve variable locality.
11799
11800 2001-12-05 Akim Demaille <akim@epita.fr>
11801
11802 * src/conflicts.c (print_reductions): Pessimize, but clarify.
11803
11804 2001-12-05 Akim Demaille <akim@epita.fr>
11805

11807
11808 2001-12-05 Akim Demaille <akim@epita.fr>
11809
11810 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
11811 * src/lalr.c: Use them.
11812
11813 2001-12-05 Akim Demaille <akim@epita.fr>
11814
11815 * src/LR0.c (augment_automaton): Formatting changes.
11816 Better variable locality.
11817
11818 2001-12-05 Akim Demaille <akim@epita.fr>
11819
11820 * src/lalr.c (matrix_print): New.
11821 (transpose): Use it.
11822 Use arrays instead of pointers.
11823
11824 2001-12-05 Akim Demaille <akim@epita.fr>
11825
11826 * src/lalr.c (maxrhs): Move to...
11827 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
11828 * src/lalr.c (build_relations): Adjust.
11829
11830 2001-12-05 Akim Demaille <akim@epita.fr>
11831
11832 * src/lalr.c (transpose): Free the memory allocated to the
11833 argument, as it is replaced by the results by the unique caller.
11834 (build_relations): Merely invoke transpose: it handles the memory
11835 deallocation.
11836 Improve variable locality.
11837 Avoid variables used as mere abbreviations.
11838 (compute_lookaheads): Use arrays instead of pointers.
11839
11840 2001-12-05 Akim Demaille <akim@epita.fr>

11856 2001-12-05 Akim Demaille <akim@epita.fr>
11857
11858 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
11859 the handling of squeue.
11860 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11861
11862 2001-12-05 Akim Demaille <akim@epita.fr>
11863
11864 Because useless nonterminals are now kept alive (instead of being
11865 `destroyed'), we now sometimes examine them, and store information
11866 related to them. Hence we need to know their number, and adjust
11867 memory allocations.
11868
11869 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
11870 static.
11871 * src/LR0.c (allocate_itemsets): The memory allocated to
11872 `symbol_count' was used for two different purpose: once to count
11873 the number of occurrences of each symbol, and later reassigned to
11874 `shift_symbol', containing the symbol that can be shifted from a
11875 given state.
11876 Deobfuscate, i.e., allocate, use and free `symbol_count' here
11877 only, and...
11878 (new_itemsets): Allocate `shift_symbol' here.
11879 (allocate_itemsets): symbol_count includes useless nonterminals.
11880 Make room for them.
11881 (free_storage): Use `free', not `XFREE', for pointers that cannot
11882 be null.
11883
11884 2001-12-05 Akim Demaille <akim@epita.fr>
11885
11886 * src/nullable.c (set_nullable): Deobfuscate the handling of
11887 ritem.
11888 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11889
11890 2001-12-05 Akim Demaille <akim@epita.fr>
11891
11892 * src/gram.c, src/gram.h (ritem_print): New.
11893 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
11894 (This useless function was defined only to work around VMS linkers
11895 that can't handle compilation units with variables only).
11896 * src/reduce.c (dump_grammar): Use it to trace the construction of
11897 ritem.
11898
11899 2001-12-04 Paul Eggert <eggert@twinsun.com>
11900
11901 * src/bison.simple (union yyalloc): Change member names
11902 to be the same as the stack names.
11903 (yyparse): yyptr is now union yyalloc *, not char *.
11904 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
11905 and may generate better code on some machines.
11906 (yystpcpy): Use prototype if __STDC__ is defined, not just
11907 if __cplusplus is defined.
11908
11909 2001-11-30 Akim Demaille <akim@epita.fr>
11910
11911 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
11912 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
11913 Gettext doesn't compile cleanly, and dies with -Werror.
11914 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
11915 Include WARNING_CFLAGS here.
11916 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
11917 before being defined.
11918
11919 2001-11-27 Paul Eggert <eggert@twinsun.com>
11920
11921 * lib/quotearg.h (quotearg_n, quotearg_n_style):
11922 First arg is int, not unsigned.
11923 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
11924 (SIZE_MAX, UINT_MAX): New macros.
11925 (quotearg_n_options): Abort if N is negative.
11926 Avoid overflow check on hosts where size_t is 64 bits and int
11927 is 32 bits, as overflow is impossible there.
11928 Fix off-by-one typo that caused unnecessary reallocation.
11929
11930 2001-11-29 Paul Eggert <eggert@twinsun.com>
11931
11932 Name space cleanup in generated parser.

11934 * doc/bison.texinfo (Bison Parser): Discuss system headers
11935 and their effect on the user name space.
11936
11937 * src/bison.simple:
11938 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
11939 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
11940 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
11941
11942 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
11943 on user names when possible.
11944
11945 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
11946 Simplify test for whather <alloca.h> exists.
11947
11948 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
11949
11950 (<stdio.h>): Include if YYDEBUG.
11951
11952 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
11953 ! defined (yyoverflow) && ! defined (yymemcpy).
11954
11955 (yymemcpy, yyparse): Rename local variables as needed so that
11956 they all begin with 'yy'.
11957
11958 (yystrlen, yystpcpy): New functions.
11959
11960 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
11961 All uses changed.
11962
11963 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
11964 instead of relying on string.h functions. Use YYSTACK_ALLOC
11965 and YYSTACK_FREE instead of malloc and free.
11966
11967 2001-11-30 Akim Demaille <akim@epita.fr>
11968
11969 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

11976
11977 2001-11-30 Akim Demaille <akim@epita.fr>
11978
11979 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
11980 if body instead of `;' to pacify GCC's warnings.
11981
11982 2001-11-30 Akim Demaille <akim@epita.fr>
11983
11984 Instead of mapping the LHS of unused rules to -1, keep the LHS
11985 valid, but flag the rules as invalid.
11986
11987 * src/gram.h (rule_t): `useful' is a new member.
11988 * src/print.c (print_grammar): Adjust.
11989 * src/derives.c (set_derives): Likewise.
11990 * src/reader.c (packgram, reduce_output): Likewise.
11991 * src/reduce.c (reduce_grammar_tables): Likewise.

11997 * src/print.c (print_results, print_grammar): Likewise.
11998 * tests/regression.at (Rule Line Numbers)
11999 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
12000
12001 2001-11-30 Akim Demaille <akim@epita.fr>
12002
12003 * src/reduce.c (nonterminals_reduce): Instead of throwing away
12004 useless nonterminals, move them at the end of the symbol arrays.
12005 (reduce_output): Adjust.
12006 * tests/reduce.at (Useless Nonterminals): Adjust.
12007
12008 2001-11-30 Akim Demaille <akim@epita.fr>
12009
12010 * src/reduce.c: Various comment/formatting changes.
12011 (nonterminals_reduce): New, extracted from...
12012 (reduce_grammar_tables): here.
12013 (reduce_grammar): Call nonterminals_reduce.
12014
12015 2001-11-29 Paul Eggert <eggert@twinsun.com>
12016

12018 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
12019 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
12020 New macros.
12021 (union yyalloc): New type.
12022 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
12023 an arbitrary restriction on hosts where size_t is wider than int.
12024
12025 (yyparse): Don't dump core if alloca or malloc fails; instead, report
12026 a parser stack overflow. Allocate just one block of memory for all
12027 three stacks, instead of allocating three blocks; this typically is
12028 faster and reduces fragmentation.
12029
12030 Do not limit the number of items in the stack to a value that fits
12031 in 'int', as this is an arbitrary limit on hosts with 64-bit
12032 size_t and 32-bit int.
12033
12034 2001-11-29 Marc Autret <autret_m@epita.fr>
12035
12036 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

12071
12072 2001-11-28 Marc Autret <autret_m@epita.fr>
12073
12074 * src/bison.simple: Fix debug.
12075 [YYERROR_VERBOSE]: Re-integrate as an internal macro.
12076
12077 2001-11-28 Akim Demaille <akim@epita.fr>

12081
12082 2001-11-28 Akim Demaille <akim@epita.fr>
12083
12084 * src/closure.c (closure): `b' and `ruleno' denote the same value:

12088
12089 * src/closure.c (closure): Instead of looping over word in array

12093
12094 * src/closure.c (closure): No longer optimize the special case
12095 where all the bits of `ruleset[r]' are set to 0, to make the code
12096 clearer.
12097
12098 2001-11-28 Akim Demaille <akim@epita.fr>
12099
12100 * src/closure.c (closure): `r' and `c' are new variables, used to
12101 de-obfuscate accesses to RULESET and CORE.
12102

12180
12181 2001-11-26 Akim Demaille <akim@epita.fr>
12182
12183 * src/LR0.c (allocate_itemsets): kernel_size contains ints, not
12184 size_ts.
12185
12186 2001-11-26 Akim Demaille <akim@epita.fr>
12187
12188 * src/complain.c, src/complain.h (error): Remove, provided by

12197
12198 2001-11-26 Akim Demaille <akim@epita.fr>

12230
12231 2001-11-23 Akim Demaille <akim@epita.fr>
12232
12233 Attaching lineno to buckets is stupid, since only one copy of each

12460 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:

12488 * src/lex.c (parse_percent_token): Replace equal_offset with

13890 * src/reader.c (read_declarations): Adjust.
13891 * src/files.c (open_files): Don't call `compute_base_names', don't
13892 compute `attrsfile' since they depend upon data which might be
13893 *in* the input file now.
13894 (output_files): Do it here.
13895 * src/output.c (output_headers): Document the fact that this patch

13973 * src/output.c (output_parser): Compute the `#line' lines when
13974 there are.
13975 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
13976 Suggested by Hans Aberg.
13977
13978 2000-12-19 Akim Demaille <akim@epita.fr>
13979
13980 Let the handling of the skeleton files be local to the procedures
13981 that use it.
13982

13984 longer static.

13987 * src/files.h: Adjust.
13988 * src/output.c (output_parser): Open and close the file to the
13989 skeleton.
13990 * src/reader.c (read_declarations): When %semantic_parser, open

13997
13998 2000-12-19 Akim Demaille <akim@epita.fr>
13999
14000 * src/files.c (open_files): Yipee! We no longer need all the code
14001 looking for `/tmp' since we have no tmp file.
14002
14003 2000-12-19 Akim Demaille <akim@epita.fr>
14004
14005 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

14015 `timestamp' and `text' in the default YYLTYPE.
14016
14017 2000-12-12 Akim Demaille <akim@epita.fr>

14031
14032 * lib/obstack.h: Formatting changes.
14033 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
14034 prevents type checking.
14035 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
14036 cast the value to (void *): assigning a `foo *' to a `void *'
14037 variable is valid.
14038 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
14039 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
14040 append characters.

14042 2000-11-17 Akim Demaille <akim@epita.fr>
14043

14055
14056 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
14057 macros.

14082 * src/output.c (output): Remove useless variables.
14083 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
14084 argument `data' for consistency with the prototypes.
14085 Qualify it `const'.
14086 (obstack_copy, obstack_copy0): Rename the second argument as
14087 `address' for consistency. Qualify it `const'.
14088 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
14089 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
14090 `const' their input argument (`data' or `address').
14091 Adjust the corresponding macros to include `const' in casts.
14092
14093 2000-11-03 Akim Demaille <akim@epita.fr>
14094
14095 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

14098
14099 2000-11-03 Akim Demaille <akim@epita.fr>
14100
14101 For some reason, this was not applied.
14102
14103 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

14117 (output_files): this.
14118 Use `obstack_save'.
14119 * src/main.c (main): Don't use `atexit' to register `done', since
14120 it no longer has to remove tmp files, just call `output_files'
14121 when there are no errors.

14143
14144 2000-11-01 Akim Demaille <akim@epita.fr>
14145

14155
14156 Introduce obstacks.

14192
14193 * src/reader.c (copy_comment2): Expect the input stream to be on
14194 the `/' which is suspected to open a comment, instead of being
14195 called after `//' or `/*' was read.
14196 (copy_comment, copy_definition, parse_union_decl, copy_action)
14197 (copy_guard): Adjust.
14198
14199 2000-10-16 Akim Demaille <akim@epita.fr>
14200
14201 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
14202 `read_signed_integer'.
14203
14204 2000-10-16 Akim Demaille <akim@epita.fr>
14205
14206 * src/reader.c (copy_dollar): New function.
14207 (copy_guard, copy_action): Use it.
14208
14209 2000-10-16 Akim Demaille <akim@epita.fr>
14210

14220
14221 2000-10-04 Akim Demaille <akim@epita.fr>
14222
14223 * doc/bison.texinfo: Various typos spotted by Neil Booth.
14224
14225 2000-10-04 Akim Demaille <akim@epita.fr>
14226
14227 When a literal string is used to define two different tokens,
14228 `bison -v' segfaults.
14229 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
14230
14231 * tests/regression.m4: New file.
14232 Include the core of the sample provided by Piotr Gackiewicz.

14234 properly.
14235
14236 2000-10-04 Akim Demaille <akim@epita.fr>
14237
14238 * src/reader.c (parse_expect_decl): Keep `count' within the size
14239 of `buffer'.
14240 From Neil Booth.
14241
14242 2000-10-02 Paul Eggert <eggert@twinsun.com>
14243
14244 * bison.s1 (yyparse): Assign the default value
14245 unconditionally, to avoid a GCC warning and make the parser a
14246 tad smaller.
14247
14248 2000-10-02 Akim Demaille <akim@epita.fr>
14249
14250 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
14251 options.
14252
14253 2000-10-02 Akim Demaille <akim@epita.fr>
14254
14255 * src/derives.c, src/print.c, src/reduce.c: To ease the
14256 translation, move some `\n' out of the translated strings.
14257
14258 2000-10-02 Akim Demaille <akim@epita.fr>
14259
14260 The location tracking mechanism is precious for parse error
14261 messages. Nevertheless, it is enabled only when `@n' is used in
14262 the grammar, which is a different issue (you can use it in error
14263 message, but not in the grammar per se). Therefore, there should
14264 be another means to enable it.
14265
14266 * src/getargs.c (getargs): Support `--locations'.
14267 (usage): Report it.
14268 * src/getargs.h (locationsflag): Export it.
14269 * src/lex.c (percent_table): Support `%locations'.
14270 * src/reader.c (yylsp_needed): Remove this variable, now replaced
14271 with `locationsflag'.
14272 * doc/bison.texinfo: Document `--locations' and `%locations'.
14273 Sort the options.
14274 * tests/calc.m4: Test it.
14275
14276 For regularity of the names, replace each
14277 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
14278 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
14279 In addition replace each `flag' with `_flag'.
14280
14281 2000-10-02 Akim Demaille <akim@epita.fr>
14282
14283 Also test parse error messages, including with YYERROR_VERBOSE.
14284
14285 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
14286 associative).
14287 Use it to check the computations.
14288 Use it to check `nonassoc' is honored.
14289 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
14290 `--yyerror-verbose'.
14291 (_AT_CHECK_CALC): Adjust to this option.
14292 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
14293
14294 2000-10-02 Akim Demaille <akim@epita.fr>
14295
14296 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14297 the latter demonstrates a flaw in the handling of non debugging
14298 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14299 was used in order to simplify:
14300
14301 #if YYDEBUG
14302 if (yydebug)
14303 {
14304 ...
14305 }
14306 #endif
14307
14308 into
14309
14310 if (yydebug)
14311 {
14312 ...
14313 }
14314
14315 unfortunately this leads to a CPP conflict when
14316 `--name-prefix=foo' is used since it produces `#define yydebug
14317 foodebug'.
14318
14319 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
14320 (YYDPRINTF): New macro.
14321 Spread its use.
14322 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
14323 the bison options.
14324 Also test `--verbose', `--defines' and `--name-prefix'.
14325
14326 2000-10-02 Akim Demaille <akim@epita.fr>
14327
14328 Improve the readability of the produced parsers.
14329
14330 * src/bison.s1: Formatting changes.
14331 Improve the comment related to the `$' mark.
14332 (yydefault): Don't fall through to `yyresume': `goto' there.
14333 * src/output.c (output_parser): When the `$' is met, skip the end
14334 of its line.
14335 New variable, `number_of_dollar_signs', to check there's exactly
14336 one `$' in the parser skeleton.
14337
14338 2000-10-02 Akim Demaille <akim@epita.fr>
14339
14340 * lib/xstrdup.c: New file, from the fileutils.
14341 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
14342 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
14343 instead of strlen + xmalloc + strcpy.
14344 * src/symtab.c (copys): Remove, use xstrdup instead.
14345
14346 2000-10-02 Akim Demaille <akim@epita.fr>
14347
14348 * src/gram.h (associativity): New enum type which replaces the
14349 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
14350 `right_assoc', `left_assoc' and `non_assoc'.
14351 Adjust all dependencies.
14352 * src/reader.c: Formatting changes.
14353 (LTYPESTR): Don't define it, use it as a literal in
14354 `reader_output_yylsp'.
14355 * src/symtab.h (symbol_class): New enum type which replaces the
14356 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
14357 `sunknown', `stoken and `snterm'.
14358
14359 2000-10-02 Akim Demaille <akim@epita.fr>
14360
14361 * src/getargs.c (fixed_outfiles): Rename as...
14362 (yaccflag): for consistency and accuracy.
14363 Adjust dependencies.
14364
14365 2000-10-02 Akim Demaille <akim@epita.fr>
14366
14367 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
14368 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
14369 difficult and introduced a lot of core dump. It turns out that
14370 Bison used an implementation of `xmalloc' based on `calloc', and
14371 at various places it does depend upon the initialization to 0. I
14372 have not tried to isolate the pertinent places, and all the former
14373 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
14374 someone should address this issue.
14375
14376 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
14377 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
14378 files.
14379 Adjust dependencies.

14381 Propagate.
14382
14383 2000-10-02 Akim Demaille <akim@epita.fr>
14384
14385 Various anti-`extern in *.c' changes.
14386
14387 * src/system.h: Include `assert.h'.
14388
14389 2000-10-02 Akim Demaille <akim@epita.fr>
14390
14391 * src/state.h (nstates, final_state, first_state, first_shift)
14392 (first_reduction): Move their exportation from here...
14393 * src/LR0.h: to here.
14394 Adjust dependencies.
14395 * src/getargs.c (statisticsflag): New variable.
14396 Add support for `--statistics'.
14397 Adjust dependencies.
14398
14399 Remove a lot of now useless `extern' statements in most files.
14400
14401 2000-10-02 Akim Demaille <akim@epita.fr>
14402
14403 * src/LR0.h: New file.
14404 Propagate its use.
14405
14406 2000-10-02 Akim Demaille <akim@epita.fr>
14407
14408 * src/print.h: New file.
14409 Propagate its use.
14410 * src/print.c: Formatting and ordering changes.
14411 (verbose, terse): Replace with...
14412 (print_results): this new function.

14476
14477 `user_toknums' is output as a `short[]' in `output.c', while it is

14526 definitions in config.h.
14527
14528 2000-09-20 Akim Demaille <akim@epita.fr>
14529

14744 Change the handling of @s so that they behave exactly like $s.
14745 There is now a pseudo variable @$ (readble and writable), location
14746 of the lhs of the rule (by default ranging from the location of
14747 the first symbol of the rhs, to the location of the last symbol,

14783 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

15462 declaration to allow a multi-character symbol as an alias.
15463 (parse_thong_decl): New function.

15474 Revised and use multiple warnxxx functions to avoid using VARARGS1.
15475 (read_declarations): Improve the error message for
15476 an invalid character. Do not abort.

15504 (lex): Use literalchar.
15505 (lex): Implemented "..." tokens.
15506 (literalchar, lex, parse_percent_token): Made tokenbuffer
15507 always contain the token. This includes growing the token
15508 buffer while reading an integer.
15509 (parse_percent_token): Replaced if-else statement with percent_table.
15510 (parse_percent_token): Added % declarations as another
15511 way to specify the flags -n, -l, and -r. Also added hooks for
15512 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
15513 major changes to files.c.
15514 (lex) Retain in the incoming stream a character following
15515 an incorrect '/'.
15516 (skip_white_space, lex): Revised most error messages
