[bison.git] / ChangeLog
1 2008-11-25 Akim Demaille <demaille@gostai.com>
2
3 b4_tables_map.
4 The point is to factor the generation of the tables across skeletons.
5 This is language dependant.
6
7 * data/c.m4 (b4_comment_): New.
8 Should be usable to define how to generate tables independently of
9 the language.
10 (b4_c_comment): New.
11 (b4_comment): Bounce to b4_c_comment.
12 Now support $2 = [PREFIX] for indentation.
13 * data/lalr1.cc (b4_table_declare): Don't output a comment if
14 there is no comment.
15 Indent it properly when there is one.
16 Output the ending semicolon.
17 (b4_table_define): Space changes.
18 Output the ending semicolon.
19 (b4_tables_map): New.
20 Use it twice instead of declaring and defining the (integral)
21 tables by hand.
22
23 2008-11-25 Akim Demaille <demaille@gostai.com>
24
25 b4_table_declare.
26 * data/lalr1.cc (b4_table_declare): New.
27 Use it to declare the tables defined with b4_table_define.
28 (b4_table_define): Declare a third arg to match b4_table_declare
29 signature.
30 Move all the comments around invocations of b4_table_define into
31 the invocations itselves.
32 Move things around to have the order for declarations and
33 definitions.

63 (Option Cross Key): Implement FIXME: listing directives also.
64 * build-aux/cross-options.pl: Read from <STDIN> rather than <>.
65 (Short Option): Special case -d. Put arguments inside @option.
66 (Bison Directive): Add column, automatically extracted from
67 src/scan-gram.l (actual name passed as the first argument)
68 with special case for %define.

99
100 Regen.
101 * src/parse-gram.h, src/parse-gram.c: Regen.
102
103 2008-11-18 Akim Demaille <demaille@gostai.com>
104
105 Use b4_subtract where possible.
106 * data/lalr1.cc (b4_subtract): Move to...
107 * data/bison.m4: here.
108 * data/glr.c (b4_rhs_data): Use it.
109 * data/yacc.c (b4_rhs_value, b4_rhs_location): Use it.

117
118 Simplify last patch slightly.

125 pointer.
126
127 2008-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
128
129 Don't let maintainer-*-check targets force a version update.
130 * cfg.mk (_is-dist-target): Implement. maintainer-check* was already
131 handled.
132
133 2008-11-17 Di-an Jan <dianj@freeshell.org>
134
135 * doc/bison.texinfo: Synchronize ``Detail Node Listing''.
136 Align menus. Adjust word wrapping. Use node names for menu names.

138 (LocalWords): Remove abbreviations.
139 (Copying): Make description a sentence.
140 (Java Action Features): Remove period to match the rest of menu.
141
142 2008-11-17 Di-an Jan <dianj@freeshell.org>
143
144 Handles several --enable-gcc-warnings.
145 * src/getargs.c (command_line_location): Set parameters to void.
146 * src/output.c (symbol_type_name_cmp): Make static.

154
155 2008-11-17 Di-an Jan <dianj@freeshell.org>
156
157 * tests/c++.at (AT_CHECK_VARIANTS): Fixes tests 198-202.

159
160 2008-11-16 Akim Demaille <demaille@gostai.com>
161
162 Add missing $(EXEEXT).
163 * doc/local.mk ($(CROSS_OPTIONS_TEXI)): The target is
164 "src/bison$(EXEEXT)".
165 Reported by Di-an Jan.
166
167 2008-11-15 Akim Demaille <demaille@gostai.com>
168
169 * TODO: Update.
170
171 2008-11-15 Akim Demaille <demaille@gostai.com>
172
173 Formatting changes.
174 * tests/input.at: here.
175
176 2008-11-15 Akim Demaille <demaille@gostai.com>
177
178 Remove duplicate header inclusion.
179 * src/LR0.c: here.
180
181 2008-11-15 Akim Demaille <demaille@gostai.com>
182
183 * src/parse-gram.h, src/parse-gram.c: Regen.
184
185 2008-11-15 Akim Demaille <demaille@gostai.com>
186
187 Support parametric types.
188
189 There are two issues to handle: first scanning nested angle
190 bracket pairs to support types such as std::pair< std::string,
191 std::list<std::string> > >.
192
193 Another issue is to address idiosyncracies of C++: do not glue two
194 closing angle brackets together (otherwise it's operator>>), and
195 avoid sticking blindly a TYPE to the opening <, as it can result
196 in '<:' which is a digraph for '['.
197
198 * src/scan-gram.l (brace_level): Rename as...
199 (nesting): this.
200 (SC_TAG): New.
201 Implement support for complex tags.
202 (tag): Accept
203 , but not <.
204 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
205 (b4_symbol_variant): Leave space around types as parameters.
206 * examples/variant.yy: Use nested template types and leading ::.
207 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
208 Rename as...
209 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
210 * tests/c++.at: Test parametric types.
211
212 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
213
214 Test token.prefix.
215 This is not sufficient, but we test at least that the make_SYMBOL
216 interface is not affected by token.prefix. A more general test
217 will be implemented when the support of token.prefix is generalized
218 to more skeletons.
219
220 * tests/c++.at: One more variant test, using token.prefix.
221
222 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
223
224 Test the make_TOKEN interface.
225 * tests/c++.at (AT_CHECK_VARIANTS): Require and use locations.
226 Factor the common code in yylex.
227 Use it to test "%define lex_symbol".
228
229 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
230
231 Formatting change.
232
233 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
234
235 Simplify code for variants bench marks.
236 * etc/bench.pl.in (&generate_grammar_list): Define and use
237 location_type.
238 Factor the common code in yylex.
239
240 2008-11-15 Akim Demaille <demaille@gostai.com>
241
242 Better error message.
243 * bootstrap (find_tool): Fix the error message.
244
245 2008-11-15 Akim Demaille <demaille@gostai.com>
246
247 Update variant.yy to newest interface.
248 * examples/variant.yy: Define lex_symbol.
249 Adjust.
250
251 2008-11-15 Akim Demaille <demaille@gostai.com>
252
253 Don't use locations in variant.yy.
254 * examples/variant.yy: Adjust to not using locations.
255
256 2008-11-15 Akim Demaille <demaille@gostai.com>
257
258 Comment changes.
259 * data/local.mk, etc/local.mk, examples/local.mk: Use Automake
260 comments for the license.
261
262 2008-11-15 Akim Demaille <demaille@gostai.com>
263
264 Remove tests/Makefile.am.
265 * tests/Makefile.am: Rename as...
266 * tests/local.mk: this.
267 * Makefile.am, configure.ac: Adjust.
268 * Makefile.am (DISTCLEANFILES): Define.
269 (maintainer-check, maintainer-xml-check, maintainer-push-check):
270 Remove, we no longer need to bounce to the real targets.
271
272 2008-11-15 Akim Demaille <demaille@gostai.com>
273
274 Comment changes.
275
276 2008-11-15 Akim Demaille <demaille@gostai.com>
277
278 djgpp/local.mk.
279 * Makefile.am (EXTRA_DIST): Move djgpp related part to...
280 * djgpp/local.mk: this new file.
281
282 2008-11-15 Akim Demaille <demaille@gostai.com>
283
284 Remove doc/Makefile.am.
285 * doc/Makefile.am: Rename as...
286 * doc/local.mk: this.
287 Adjust paths
288 * Makefile.am, configure.ac: Adjust.
289 * Makefile.am (MOSTLYCLEANFILES): New.
290 * src/local.mk: Adjust.
291
292 2008-11-15 Akim Demaille <demaille@gostai.com>
293
294 Move sc_tight_scope into maint.mk.
295 It does not work, and I don't know how it was supposed to work: it
296 seems to be looking for sources in the build tree. I just moved
297 it at a better place, fixing it is still required.
298
299 * src/local.mk (echo): Remove.
300 (sc_tight_scope): Move to...
301 * maint.mk: here.
302
303 2008-11-15 Akim Demaille <demaille@gostai.com>
304
305 Regen.
306 * src/parse-gram.h, src/parse-gram.h: Regen.
307
308 2008-11-15 Akim Demaille <demaille@gostai.com>
309
310 Remove src/Makefile.am.
311 * src/Makefile.am: Rename as...
312 * src/local.mk: this.
313 Prefix all the paths with src/.
314 (AUTOMAKE_OPTIONS): Build object files in the sub dirs.
315 (AM_CPPFLAGS): Find find in builddir/src.
316 (YACC): Move the flags into...
317 (AM_YFLAGS): here.
318 * maint.mk (sc_tight_scope): Disable.
319 It used to bounce to the version in src/Makefile.am which is now
320 part of this very Makefile.
321 * Makefile.am, configure.ac: Adjust.
322 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
323 include "..." to find files "here": we are no longer in src/, so
324 qualify the includes with src/.
325 * doc/Makefile.am (PREPATH): No longer include the top_builddir
326 prefix.
327 (.x.1): Adjust to be able to create src/foo from the top level
328 Makefile, instead of going bounce to src/Makefile the creation of
329 foo.
330
331 2008-11-15 Akim Demaille <demaille@gostai.com>
332
333 Remove useless variable.
334 * doc/Makefile.am (srcsrcdir): Remove.
335
336 2008-11-15 Akim Demaille <demaille@gostai.com>
337
338 Remove data/Makefile.am.
339 * data/Makefile.am: Rename as...
340 * data/local.mk: this.
341 Adjust paths.
342 * Makefile.am, configure.ac: Adjust.
343
344 2008-11-15 Akim Demaille <demaille@gostai.com>
345
346 Remove etc/Makefile.am.
347 * etc/Makefile.am: Rename as...
348 * etc/local.mk: this.
349 Adjust.
350 * Makefile.am, configure.ac: Adjust.
351
352 2008-11-15 Akim Demaille <demaille@gostai.com>
353
354 Remove examples/local.mk.
355 examples/calc++/Makefile.am might be interesting to keep as is, since
356 it is an example in itself.
357
358 * examples/Makefile.am: Rename as...
359 * examples/local.mk: this.
360 Adjust.
361 * Makefile.am, configure.ac: Adjust.
362
363 2008-11-15 Akim Demaille <demaille@gostai.com>
364
365 Remove build-aux/Makefile.am.
366 Recursive Makefiles are really way too slow, let's get rid of some of
367 them.
368
369 * build-aux/Makefile.am: Rename as...
370 * build-aux/local.mk: this.
371 Adjust paths.
372 * Makefile.am, configure.ac: Adjust.
373
374 2008-11-15 Akim Demaille <demaille@gostai.com>
375
376 Provide convenience constructors for locations and positions.
377 * data/location.cc (position::position): Accept file, line and
378 column as arguments with default values.
379 Always qualify initial line and column literals as unsigned.
380 (location::location): Provide convenience constructors.
381
382 2008-11-15 Akim Demaille <demaille@gostai.com>
383
384 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
385 token type.
386 Using template buys us nothing, and makes it uselessly complex to
387 construct a symbol. Besides, it could not be generalized to other
388 languages, while make_FOO would work in C/Java etc.
389
390 * data/lalr1.cc (b4_symbol_): New.
391 (b4_symbol): Use it.
392 (b4_symbol_constructor_declaration_)
393 (b4_symbol_constructor_definition_): Instead of generating
394 specializations of an overloaded template function, just generate
395 several functions whose names are forged from the token names
396 without the token.prefix.
397 (b4_symbol_constructor_declarations): Generate them for all the
398 symbols, not just by class of symbol type, now that instead of
399 specializing a function template by the token, we generate a
400 function named after the token.
401 (b4_symbol_constructor_specialization_)
402 (b4_symbol_constructor_specializations): Remove.
403 * etc/bench.pl.in: Adjust to this new API.
404
405 2008-11-13 Akim Demaille <demaille@gostai.com>
406
407 %define token.prefix.
408 Provide a means to add a prefix to the name of the tokens as
409 output in the generated files. Because of name clashes, it is
410 good to have such a prefix such as TOK_ that protects from names
411 such as EOF, FILE etc. But it clutters the grammar itself.
412
413 * data/bison.m4 (token.prefix): Empty by default.
414 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
415 * data/lalr1.cc (b4_symbol): Ditto.
416
417 2008-11-13 Akim Demaille <demaille@gostai.com>
418
419 Compute at M4 time some of the subtractions.
420 * data/lalr1.cc (b4_subtract): New.
421 (b4_rhs_data): Use it.
422
423 2008-11-13 Akim Demaille <demaille@gostai.com>
424
425 symbol::token.
426 This allows the user to get the type of a token returned by yylex.
427
428 * data/lalr1.cc (symbol::token): New.
429 (yytoknum_): Define when %define lex_symbol, independently of
430 %debug.
431 (yytoken_number_): Move into...
432 (symbol::token): here, since that's the only use.
433 The other one is YYPRINT which was not officially supported
434 by lalr1.cc, and anyway it did not work since YYPRINT uses this
435 array under a different name (yytoknum).
436
437 2008-11-13 Akim Demaille <demaille@gostai.com>
438
439 YYERRCODE.
440 * TODO (YYERRCODE): Mention the case of $undef.
441
442 2008-11-13 Akim Demaille <demaille@gostai.com>
443
444 TODO: YYPRINT.
445 * TODO (YYPRINT): New.
446
447 2008-11-13 Akim Demaille <demaille@gostai.com>
448
449 Comment changes.
450 * data/lalr1.cc, data/yacc.c: Fix the description of the
451 yytranslate and yytoknum tables.
452
453 2008-11-13 Akim Demaille <demaille@gostai.com>
454
455 Define make_symbol in the header.
456 To reach good performances these functions should be inlined (yet
457 this is to measure precisely). To this end they must be available
458 to the caller.
459
460 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
461 location_type with the class name.
462 Since will now be output in the header, declare "inline".
463 No longer use b4_symbol_constructor_specializations, but
464 b4_symbol_constructor_definitions in the header.
465 Don't call it in the *.cc file.
466
467 2008-11-13 Akim Demaille <demaille@gostai.com>
468
469 Define yytranslate in the header for lex_symbol.
470 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
471 into the header file when using %define lex_symbol.
472 (yytranslate_): Declare inline.
473
474 2008-11-13 Akim Demaille <demaille@gostai.com>
475
476 Define the constructors of symbol_type in
477 b4_symbol_constructor_definitions.
478 The constructors are called by the make_symbol functions, which a
479 forthcoming patch will move elsewhere. Hence the interest of
480 putting them together.
481
482 The stack_symbol_type does not need to be moved, it is used only
483 by the parser.
484
485 * data/lalr1.cc: Move symbol_type and symbol_base_type
486 constructors into...
487 (b4_symbol_constructor_definitions): here.
488 Adjust.
489
490 2008-11-13 Akim Demaille <demaille@gostai.com>
491
492 Make it easier to move the definition of yytranslate_.
493 Forthcoming changes will make it possible to use yytranslate_
494 from outside the parser implementation file.
495
496 * data/lalr1.cc (b4_yytranslate_definition): New.
497 Use it.
498
499 2008-11-13 Akim Demaille <demaille@gostai.com>
500
501 Remove useless class specification.
502 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
503 to refer to the class name to use a type defined by the class for
504 arguments of member functions.
505
506 2008-11-13 Akim Demaille <demaille@gostai.com>

508 Finer input type for yytranslate.
509 This patch is debatable: the tradition expects yylex to return an int
510 which happens to correspond to token_number (which is an enum). This
511 allows for instance to return characters (such as '*' etc.). But this
512 goes against the stronger typing I am trying to have with the new
513 lex interface which return a symbol_type. So in this case, feed
514 yytranslate_ with a token_type.
515
516 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
517 expect a token_type.
518

520
521 Honor lex-params in %define lex_symbol mode.
522 * data/lalr1.cc: Use b4_lex_param.

525
526 Simplify names.
527 * src/output.c (symbol_definitions_output): Rename symbol
528 attributes type_name and has_type_name as type and has_type.
529 * data/lalr1.cc: Adjust uses.
530
531 2008-11-13 Akim Demaille <demaille@gostai.com>
532
533 Use b4_type_names for the union type.
534 The union used to compute the size of the variant used to iterate
535 over the type of all the symbols, with a lot of redundancy. Now
536 iterate over the lists of symbols having the same type-name.
537
538 * data/lalr1.cc (b4_char_sizeof_): New.
539 (b4_char_sizeof): Use it.
540 Adjust to be called with a list of numbers instead of a single
541 number.
542 Adjust its caller for new-line issues.
543
544 2008-11-13 Akim Demaille <demaille@gostai.com>
545
546 Define the "identifier" of a symbol.
547 Symbols may have several string representations, for instance if
548 they have an alias. What I call its "id" is a string that can be
549 used as an identifier. May not exist.
550
551 Currently the symbols which have the "tag_is_id" flag set are
552 those that don't have an alias. Look harder for the id.
553
554 * src/output.c (is_identifier): Move to...
555 * src/symtab.c (is_identifier): here.
556 * src/symtab.h, src/symtab.c (symbol_id_get): New.
557 * src/output.c (symbol_definitions_output): Use it to define "id"
558 and "has_id".
559 Remove the definition of "tag_is_id".
560 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
561 "tag_is_id" were used to produce code.
562 We still use "tag" for documentation.

570 (AT_CHECK_NAMESPACE): Check the use of locations.
571 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
572 without locations with lalr1.cc.
573 Test these cases.
574 * tests/output.at: Check lalr1.cc with and without location

691 Introduce make_symbol.
692 make_symbol provides a means to construct a full symbol (kind,
693 value, location) in a single shot. It is meant to be a Symbol
694 constructor, parameterized by the symbol kind so that overloading
695 would prevent incorrect kind/value pairs. Unfortunately
696 parameterized constructors do not work well in C++ (unless the
697 parameter also appears as an argument, which is not acceptable),
698 hence the use of a function instead of a constructor.
699
700 * data/lalr1.cc (b4_symbol_constructor_declaration_)

705 (b4_symbol_constructor_definitions): New.
706 Use them where appropriate to generate declaration, declaration of
707 the specializations, and implementations of the templated
708 overloaded function "make_symbol".
709 (variant::variant): Always define a default ctor.
710 Also provide a copy ctor.
711 (symbol_base_type, symbol_type): New ctor overloads for value-less
712 symbols.
713 (symbol_type): Now public, so that functions such as yylex can use
714 it.

725 Test 214 was failing: it greps with a pattern containing [ ]*
726 which obviously meant to catch spaces and tabs, but contained only
727 spaces. Tabulations in sources are a nuisance, so to simplify the
728 matter, get rid of all the tabulations in the Java sources. The
729 other skeletons will be treated equally later.
730
731 * data/java.m4, data/lalr1.java: Untabify.

913 Change the handling of the symbols in the skeletons.
914 Before we were using tables which lines were the symbols and which
915 columns were things like number, tag, type-name etc. It is was
916 difficult to extend: each time a column was added, all the numbers had
917 to be updated (you asked for colon $2, not for "tag"). Also, it was
918 hard to filter these tables when only a subset of the symbols (say the
919 tokens, or the nterms, or the tokens that have and external number
920 *and* a type-name) was of interest.
921
922 Now instead of monolithic tables, we define one macro per cell. For
923 instance "b4_symbol(0, tag)" is a macro name which contents is
924 self-decriptive. The macro "b4_symbol" provides easier access to
925 these cells.
926
927 * src/output.c (type_names_output): Remove.
928 (symbol_numbers_output, symbol_definitions_output): New.

974 Unfortunately it is not possible to reuse the %prec directive. This
975 is because to please POSIX, we do not require to end the rules with a

977
978 foo: bar %prec baz

1111 Rely on the state stack to display reduction traces.
1112 To display rhs symbols before a reduction, we used information

1227
1228 Handle more general types of option arguments.
1229 * build-aux/cross-options.pl: The argument ends at the first
1230 space, not the first non-symbol character.
1231 Use @var for each word appearing the argument description.
1232
1233 2008-11-07 Akim Demaille <demaille@gostai.com>

1240
1241 2008-11-07 Akim Demaille <demaille@gostai.com>
1242
1243 Add "%define assert" to variants.
1244 This is used to help the user catch cases where some value gets
1245 ovewritten by a new one. This should not happen, as this will
1246 probably leak.
1247
1248 Unfortunately this uncovered a bug in the C++ parser itself: the
1249 lookahead value was not destroyed between two calls to yylex. For
1250 instance if the previous lookahead was a std::string, and then an int,
1251 then the value of the std::string was correctly taken (i.e., the
1252 lookahead was now an empty string), but std::string structure itself
1253 was not reclaimed.
1254
1255 This is now done in variant::build(other&) (which is used to take the
1256 value of the lookahead): other is not only stolen from its value, it
1257 is also destroyed. This incurs a new performance penalty of a few
1258 percent, and union becomes faster again.
1259
1260 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
1261 (b4_variant_if): New.
1262 (variant::built): New.
1263 Use it whereever the status of the variant changes.
1264 * etc/bench.pl.in: Check the penalty of %define assert.
1265
1266 2008-11-07 Akim Demaille <demaille@gostai.com>
1267
1268 Use "%define variant" in bench.pl.
1269 * etc/bench.pl.in: No longer use the pseudo directive %variants,
1270 just use %define variants.
1271
1272 2008-11-07 Akim Demaille <demaille@gostai.com>

1538
1539 Fuse the three stacks into a single one.
1540
1541 In order to make it easy to perform benchmarks to ensure that
1542 there are no performance loss, lalr1.cc is forked into
1543 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
1544 lalr1.cc.
1545
1546 Meanwhile, to make sure that lalr1-fusion.cc is correctly
1547 exercized by the test suite, the user must install a symbolic link
1548 from lalr1.cc to it.
1549
1550 Instead of having three stacks (state, value, location), use a
1551 stack of triples. This considerably simplifies the code (and it
1552 will be easier not to require locations as currently does the C++
1553 parser), and also gives a 10% speedup according to
1554 etc/bench (probably mainly since memory allocation is done once
1555 instead of three times).
1556
1557 Another motivation is to make it easier to destruct properly
1558 semantic values: now that they are bound to their state (hence
1559 symbol type) it will be easier to call the appropriate destructor.
1560
1561 These changes should probably benefit the C parser too.
1562
1563 * data/lalr1.cc: Copy as...
1564 * data/lalr1-fusion.cc: this new file.
1565 (b4_rhs_value, b4_rhs_location): New definitions overriding those
1566 from c++.m4.
1567 (state_stack_type, semantic_stack_type, location_stack_type)
1568 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
1569 (data_type, stack_type, yystack_): New.
1570 (YYLLOC_DEFAULT, yypush_): Adjust.
1571 (yyerror_range): Now based on data_type, not location_type.
1572
1573 2008-11-03 Akim Demaille <demaille@gostai.com>
1574
1575 Push the state, value, and location at the same time.
1576 This is needed to prepare a forthcoming patch that fuses the three
1577 stacks into one.
1578
1579 * data/lalr1.cc (parser::yypush_): New.
1580 (parser::yynewstate): Change the semantics: instead of arriving to
1581 this label when value and location have been pushed, but yystate
1582 is to be pushed on the state stack, now the three of them must
1583 have been pushed before. yystate still must be the new state.
1584 This allows to use yypush_ everywhere instead of individual
1585 handling of the stacks.
1586
1587 2008-11-03 Akim Demaille <demaille@gostai.com>
1588
1589 Prefer references to pointers.
1590 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
1591 definition to use references instead of pointers.
1592 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
1593 Take the value and location as references.
1594 Adjust callers.
1595
1596 2008-11-03 Akim Demaille <demaille@gostai.com>
1597
1598 stack::size instead of stack::height.
1599 * data/lalr1.cc (stack::height): Rename as...
1600 (stack::size): this.
1601 Fix the output type.
1602 Comment changes.
1603
1604 2008-11-03 Akim Demaille <demaille@gostai.com>
1605
1606 Use variants to support objects as semantic values.
1607 This patch was inspired by work by Michiel De Wilde. But he used
1608 Boost variants which (i) requires Boost on the user side, (ii) is
1609 slow, and (iii) has useless overhead (the parser knows the type of
1610 the semantic value there is no reason to duplicate this
1611 information as Boost.Variants do).
1612
1613 This implementation reserves a buffer large enough to store the
1614 largest objects. yy::variant implements this buffer. It was
1615 implemented with Quentin Hocquet.
1616
1617 * src/output.c (type_names_output): New.
1618 (output_skeleton): Invoke it.
1619 * data/c++.m4 (b4_variant_if): New.
1620 (b4_symbol_value): If needed, provide a definition for variants.
1621 * data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
1622 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
1623 (b4_char_sizeof, yy::variant): New.
1624 (parser::parse): If variants are requested, define
1625 parser::union_type, parser::variant, change the definition of
1626 semantic_type, construct $$ before running the user action instead
1627 of performing a default $$ = $1.
1628 * examples/variant.yy: New.
1629 Based on an example by Michiel De Wilde.
1630
1631 2008-11-03 Akim Demaille <demaille@gostai.com>
1632
1633 Parameterize the extraction of semantic values.
1634 To make future changes easier, no longer rely on ".TYPE" being the
1635 way to get a semantic value.
1636
1637 * data/c.m4 (b4_symbol_value): New.
1638 Use it.
1639 * data/c++.m4, data/yacc.c: Use it.
1640 * data/glr.c: Use b4_symbol_value.
1641 (b4_rhs_data): New.
1642 Use it.
1643
1644 2008-11-03 Akim Demaille <demaille@gostai.com>
1645
1646 Prepare easier M4 changes.
1647 * data/lalr1.cc: Use escaped [] instead of literals to prepare
1648 future changes.

1747
1748 Always put auxiliary code files in the same dir as other output files.
1749 * src/files.c (compute_file_name_parts): When the user specifies
1750 --output but not --file-prefix, extract the directory prefix from the
1751 file prefix not from the grammar file name. This affects the location
1752 of files like location.hh generated by the C++ skeleton. The includes
1753 in the other output files require this fix.

1826 * Makefile.maint: Remove, previously replaced by maint.mk.
1827 * Makefile.cfg: Remove, and migrate settings to...
1828 * cfg.mk: ... here for the sake of `make announcement'.

1904 declares it.
1905
1906 2008-08-07 Joel E. Denny <jdenny@ces.clemson.edu>
1907
1908 Keep .version and PACKAGE_VERSION in sync.
1909 * Makefile.am ($(top_srcdir)/.version): Declare configure as a
1910 dependency, and add comments justifying this in more detail. Discussed

1936 whereas m4_append is linear in newer m4.
1937 (m4_mkstemp): New builtin.
1938 (m4_symbols): Make rename conditional.
1939 (m4_version_prereq): Ensure fatal error if used in bison, which

1987 2008-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
1988
1989 Fix dependence on computed configure variables.
1990 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
1991 $(top_srcdir)/configure.ac so that changes to computed variables, such

2015 (EXTRA_DIST): Remove GNUmakefile, handled by Gnulib. Add maint.mk,
2016 .prev-version, and .version.
2017 * NEWS (2.3b+): Rename to...
2018 (?.?): ... this because we're dropping the "+" version naming scheme,
2019 but, in general, we still can't be sure of our next release name.
2020 * bootstrap: Add a quick hack to remove from .gitignore the
2021 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
2022 entry. This should really be fixed in gnulib instead.
2023 * bootstrap.conf (gnulib_modules): Add gnumakefile.
2024 * configure.ac (AC_INIT): Set version name by invoking

2043 Uddeborg at
2044 <http://lists.gnu.org/archive/html/bug-bison/2008-06/msg00000.html>.

2058 .gitignore entries before passing them to insert_sorted_if_absent.
2059 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
2060 .cvsignore files are maintained even though Bison developers run
2061 bootstrap while using Git.
2062 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
2063 unneeded by Bison.
2064 (gnulib): Add.
2065 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
2066 unneeded. Reported by Eric Blake.
2067 * lib/.gitignore (/*~): Add.
2068 * po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore.
2069 * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric
2070 Blake.
2071 * src/.gitignore (/bison.exe): Add. Reported by Eric Blake.

2080 (/setenv.m4): Add.
2081 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
2082 the first argument because it may become position-dependent, and unset
2083 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
2084 Add comments explaining these issues in more detail.
2085
2086 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

2147
2148 Revert prior patch, by working around autoconf regression.
2149 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
2150 ("Output file name: ("): Uncomment test.
2151 ("Output file name: )"): Likewise.
2152 Based on an idea from Noah Misch.
2153
2154 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2155
2156 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
2157 2.61. Reported by Juan Manuel Guerrero at
2158 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
2159 * tests/output.at ("Output file name: ("): Comment out test case for
2160 now.
2161 ("Output file name: )"): Likewise.
2162
2163 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

2166 succeeds.
2167
2168 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2169
2170 Update to the current gnulib CVS repository, and fix trigraph handling
2171 in Bison.
2172 * bootstrap: Update gnulib CVS repository URL.
2173 (symlink_to_dir): Encapsulate the code that guarantees the destination
2174 directory exists into...
2175 (check_dst_dir): ... this new function, and...
2176 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
2177 fail when copying files into lib/uniwidth/.
2178 * src/output.c (prepare_symbols): When writing yytname muscles, where
2179 symbol names will be encoded in C-string literals, tell quotearg to
2180 escape trigraphs. This used to be the default in gnulib.
2181 * tests/regression.at (Token definitions): Because of the change in
2182 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2183 escapes trigraphs in symbol names. Thus, yytname no longer has
2184 trigraphs unnecessarily doubly escaped. Update test case output.
2185 Extend test case to be sure Bison's own error messages will no longer
2186 have trigraphs in symbol names unnecessarily escaped once.

2200 * NEWS (2.3a+): Mention that -g now takes an argument.
2201 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
2202 consistency. Update the -g and -x entries now that they take
2203 arguments. Use brackets to indicate optional arguments.
2204 * src/getargs.c (usage): Explain the relationship between arguments of
2205 long and short options more completely. Document --defines and -d
2206 separately since the former takes an argument but, for POSIX Yacc, the
2207 latter does not.
2208 (short_options): Let -W take an optional argument like --warnings.
2209 (getargs): Sort cases.
2210

2221
2222 * src/getargs.c (short_options): Split and sort for readability.
2223 -g and -x take optional arguments, just like their long options.
2224 * build-aux/cross-options.pl: Use /x to make the regexp easier to
2225 understand.
2226 Fix the handling of $opt which resulted in all the argument to be
2227 considered as optional.
2228
2229 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

2753 2007-10-19 Joel E. Denny <jdenny@ces.clemson.edu>
2754
2755 * NEWS (2.3a+): Add entry for recent .output file lookahead set fix.
2756 * doc/bison.texinfo (Understanding): Remove a bogus lookahead set in
2757 the example .output text.
2758 * tests/regression.at (Extra lookahead sets in report): Improve wording
2759 of comments.
2760
2761 2007-10-17 Wojciech Polak <polak@gnu.org>
2762
2763 * src/print-xml.c (print_grammar): Renamed
2764 <terminal> and <nonterminal> attributes:
2765 "type" to "number" and "symbol" to "name".
2766 * data/xslt/xml2text.xsl (xsl:template match="terminal"):
2767 Use new attribute names.
2768 (xsl:template match="nonterminal"): Likewise.
2769 * data/xslt/xml2xhtml.xsl: Likewise.
2770
2771 2007-10-17 Joel E. Denny <jdenny@ces.clemson.edu>
2772
2773 * doc/bison.texinfo (Bison Options): Add entry for --print-datadir.
2774 (Option Cross Key): Likewise.
2775
2776 * src/print-xml.c (print_core): Don't print a reduction's lookahead set
2777 next to an item whose dot is not at the end of the RHS even if it
2778 happens to be associated with the same rule.
2779 * src/print.c (print_core): Likewise.
2780 * tests/conflicts.at (Unresolved SR Conflicts): Update output.
2781 (Resolved SR Conflicts): Update output.
2782 * tests/regression.at (Extra lookahead sets in report): New test case.
2783
2784 2007-10-11 Wojciech Polak <polak@gnu.org>
2785
2786 * src/print-xml.c (print_core): Remove item set
2787 redundancy.
2788 * data/xslt/bison.xsl (bison:ruleNumber): New key.
2789 Improve processing time. Suggested by Joel E. Denny.
2790 * data/xslt/xml2dot.xsl (xsl:template name="escape"):
2791 Write xsl:param "required" attribute as comment.
2792 * data/xslt/xml2text.xsl (xsl:template match="item"): New.
2793 (xsl:template match="rule"): Support new reduced itemset.
2794 (xsl:template match="point"): Remove.
2795 * data/xslt/xml2xhtml.xsl: Likewise.
2796

2800
2801 2007-10-09 Joel E. Denny <jdenny@ces.clemson.edu>
2802
2803 Make xml2dot.xsl and --graph produce the same output.
2804 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a `&#10;'
2805 instead of a `\n'. That is, don't add escapes yet or they'll be doubly
2806 escaped later.
2807 (xsl:template name="output-node"): Use the new escape template instead
2808 of the string-replace template directly.
2809 (xsl:template name="output-edge"): Likewise.

2811 addition to quotation marks.
2812 * src/graphviz.c (start_graph, output_node, output_edge): Add
2813 whitespace to output for legibility.
2814
2815 Make xml2text.xsl and --report produce the same output, and remove the
2816 XML "conflicts" element since a conflict summary is easily extracted
2817 from the automaton.
2818 * data/xslt/bison.xsl: New.
2819 (xsl:template match="state" mode="bison:count-conflicts): New.
2820 * data/xslt/xml2text.xsl: Import bison.xsl.
2821 (xsl:template match="bison-xml-report"): Instead of styling the
2822 "conflicts" element, style the "automaton" element with mode

2824 conflicts for a state on the same line.
2825 (xsl:template match="conflicts"): Remove.
2826 (xsl:template match="conflict"): Remove.
2827 (xsl:template match="terminal"): Line-wrap the list of rules in which

2831 (xsl:template match="state" mode="conflicts"): New.
2832 (xsl:template name="line-wrap"): New.
2833 (xsl:template name="ws-search"): New.
2834 * data/xslt/xml2xhtml.xsl: Import bison.xsl.
2835 (xsl:template match="bison-xml-report"): Instead of styling the
2836 "conflicts" element, style the "automaton" element with mode

2839 (xsl:template match="conflict"): Remove.
2840 (xsl:template match="automaton" mode="conflicts"): New.
2841 (xsl:template match="state" mode="conflicts): New.
2842 * src/conflicts.c (conflicts_output_xml): Remove.
2843 * src/conflicts.h (conflicts_output_xml): Remove prototype.
2844 * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml.
2845 * src/print.c (print_grammar): Consistently wrap at the 66th column so
2846 the corresponding XSLT is easier. Also, never wrap between a word and
2847 the comma that follows it.
2848
2849 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>
2850
2851 Improve C++ namespace support. Discussed starting at
2852 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
2853 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
2854 b4_namespace_close): New macros that interpret the %define variable
2855 "namespace" so its value can contain "::" to indicate nested
2856 namespaces.
2857 * data/glr.cc (b4_namespace): Don't define, and replace all uses with
2858 the above macros.
2859 * data/lalr1.cc (b4_namespace): Likewise.
2860 * data/location.cc (b4_namespace): Likewise.
2861 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
2862 inside a new table in the general %define entry. Document `%define
2863 namespace' there as well. Point the %name-prefix entry to it since it
2864 explains it more completely in the case of C++.
2865 (C++ Bison Interface): Mention `%define namespace' instead of
2866 %name-prefix.
2867 (Table of Symbols): Remove the `%define push_pull' entry. The %define
2868 entry suffices.
2869 * tests/c++.at (Relative namespace references): New test case.
2870 (Absolute namespace references): New test case.
2871 (Syntactically invalid namespace references): New test case.
2872 * tests/input.at (C++ namespace reference errors): New test case.

2879 (b4_percent_define_get_syncline): New.
2880 (b4_percent_define_flag_if): Use b4_percent_define_get_loc.
2881 (b4_percent_define_default): Record defining location as line 1 rather
2882 than 0 for the sake of synchronizing #line's, and define
2883 b4_percent_define_syncline(VARIABLE).
2884 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
2885 * src/muscle_tab.c (muscle_syncline_grow): New.
2886 (muscle_code_grow): Use muscle_syncline_grow.
2887 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and
2888 define b4_percent_define_syncline(VARIABLE).
2889 (muscle_percent_define_get_loc): New.
2890 (muscle_percent_define_get_syncline): New.
2891 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
2892 remove some unused variables.
2893 (muscle_percent_define_default): Record defining location as line 1
2894 rather than 0 for the sake of synchronizing #line's, and define
2895 b4_percent_define_syncline(VARIABLE).
2896 (muscle_percent_define_check_values): Use
2897 muscle_percent_define_get_loc.
2898 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
2899 (muscle_percent_define_get_syncline): Prototype.

2903 b4_percent_define_get_loc and b4_percent_define_get_syncline errors.
2904
2905 2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
2906
2907 Fix some error-reporting macro bugs.
2908 * data/bison.m4 (b4_cat): New.
2909 (b4_error, b4_error_at): Use b4_cat to send error directives directly
2910 to stdout so they don't become arguments to other macros. Update
2911 comments and add examples.
2912 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
2913 add examples.
2914 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
2915 after printing the error directive so that M4 doesn't report subsequent
2916 problems that are induced by this problem.
2917 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
2918 instead of just in them. Recognize @\n in both places. Both expand to
2919 the empty string. Needed by b4_cat.
2920 * tests/skeletons.at (Complaining during macro argument expansion):
2921 New test case.
2922 (Fatal errors make M4 exit immediately): New test case.
2923

2932 computation from here...
2933 (prepare): ... and from here...
2934 (compute_pkgdatadir): ... into this new function.
2935 * src/output.h (compute_pkgdatadir): Prototype.
2936
2937 2007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>
2938
2939 * src/print-xml.c (escape_bufs): New static global variable

2946
2947 Replace `%push-parser' and `%push-pull-parser' with
2948 `%define push_pull "push"' and `%define push_pull "both"'.

2951 Pull Parser Function, Parser Create Function, Parser Delete Function):
2952 Update declarations.
2953 (Decl Summary, Table of Symbols): Replace %push-parser and

2957 definitions...
2958 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
2959 definitions...
2960 * data/push.c: ... to here and compute them from the value of the
2961 %define variable push_pull.
2962 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
2963 parsing requests here...
2964 * data/yacc.c: ... hack this to switch to push.c any time
2965 b4_use_push_pull_flag or the %define variable push_pull is set. This
2966 will go away when we mv push.c yacc.c.
2967 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
2968 push parsing is not supported since unused %define variables are
2969 reported anyway.
2970 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
2971 * src/muscle_tab.h (muscle_percent_define_check_values): Update

3011 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
3012 `char const *' instead of `char *'.
3013 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
3014 local variable `sep'.
3015
3016 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
3017
3018 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
3019 elsewhere.
3020 * src/print-xml.c: Prefer "const" after types; that's more consistent.
3021 (xml_printf): Indent just 1 space for level.
3022 (e_char, xlate_char): Remove.
3023 (xml_escape_string): Rewrite to avoid undefined behavior (used

3099 initialized to 0.
3100 (yypull_parse): If yypstate_new returns 0, don't report it as memory

3177 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3178
3179 Get rid of broken %no-parser, -n, and --no-parser implementation and
3180 documentation.
3181 * TODO: Don't mention them.
3182 * doc/bison.1: Likewise.
3183 * doc/bison.texinfo (Decl Summary): Likewise.
3184 (Bison Options): Likewise.
3185 (Option Cross Key): Likewise.
3186 * src/getargs.c (no_parser_flag): Remove global variable.
3187 (usage): Don't print description of -n and --no-parser.
3188 (long_options): Remove --no-parser entry here.
3189 (getargs): Remove -n case in the switch here.
3190 * src/getargs.h (no_parser_flag): Remove extern.
3191 * tests/regression.at (Web2c Actions): Remove comment that mentions
3192 --no-parser.
3193
3194 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3195
3196 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
3197 name user variables starting with `yy'. Just pass NULL instead of a
3198 dummy local &yylval to yypush_parse.
3199 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
3200 starting with `yy'.
3201
3202 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
3203
3204 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
3205 true since it's then always used regardless of whether yyoverflow is
3206 defined. Reported by Christian Burger at
3207 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
3208 * THANKS: Add Christian Burger.
3209
3210 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3211 node names: say "Decl Summary" not "Bison Declaration Summary".
3212
3213 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
3214
3215 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
3216 determine whether this function has already complained about an invalid
3217 value for a %define boolean variable, don't check whether Bison has
3218 ever examined the value. As written, the check was a tautology.
3219 Instead, record and check for this complaint using a separate muscle.
3220
3221 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
3222
3223 Fix push parsing memory leak reported by Brandon Lucia at
3224 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
3225 * THANKS: Add Brandon Lucia.
3226 * data/push.c (yypstate_delete): Free the stack if it was reallocated
3227 but the parse never completed and thus freed it.
3228 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
3229 * tests/testsuite.at: Include push.at.
3230 * test/push.at: New.
3231 (Push Parsing: Memory Leak for Early Deletion): New test case.
3232
3233 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3234
3235 Improve handling of multiple S/R conflicts in the same state and of S/R
3236 conflicts involving multiple reductions.
3237 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3238 set for a state here or Bison will abort if it is reassigned on a
3239 later conflicted reduction in the same state.
3240 Similarly, don't finalize and assign the solved conflicts report here
3241 or it will be lost if it is reassigned on a later conflicted reduction
3242 in the same state.
3243 (set_conflicts): Instead, assign them both here after all S/R conflicts
3244 in the state have been fully examined.
3245 * src/print.c (shift_set): Rename to...
3246 (no_reduce_set): ... this.
3247 (print_reductions): Update for rename, and add %nonassoc error action
3248 tokens to no_reduce_set so that, when printing the first remaining
3249 reduction on an error action token, the reduction is enclosed in
3250 brackets.
3251 (print_results): Update for rename.
3252 * tests/conflicts.at (Solved conflicts report for multiple reductions
3253 in a state): New test case.
3254 (%nonassoc error actions for multiple reductions in a state): New test
3255 case.
3256
3257 * src/main.c (main): Don't depend on C99 features.
3258
3259 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
3260
3261 * build-aux/.cvsignore: Add compile.
3262 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
3263 uniwidth.
3264
3265 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
3266
3267 * bootstrap (slurp): Create target directories that don't exist.
3268 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
3269
3270 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3271
3272 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
3273 than item number.
3274 * closure.c (closure): Likewise.
3275 * state.h (reductions): Comment sorting of rules.
3276 (state): Comment sorting of items.
3277
3278 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
3279
3280 Fix C++ test cases after recent Gnulib changes. Discussed starting at
3281 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
3282 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
3283 definition in order to avoid Gnulib headers since we don't use config.h
3284 here.
3285 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
3286 rather than AT_DATA so that config.h is included.
3287
3288 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
3289
3290 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
3291 instead of fprintf. Guard these functions with #if YYDEBUG instead of
3292 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
3293 and so that YYFPRINTF is guaranteed to be defined here.
3294
3295 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
3296
3297 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
3298 with...
3299 (muscle_percent_define_check_values): ... this more helpful function.
3300 Again, it's not used yet, but it will be.
3301 * src/muscle_tab.h: Likewise.
3302
3303 Improve some comments in parser table construction.
3304 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
3305 (generate_states): Don't mention ruleset, which is internal to closure.
3306 * src/closure.c (closure): Explain sorting of core and itemset, which
3307 is required for this function to behave correctly.
3308 * src/closure.h (closure): Mention sorting.
3309
3310 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
3311
3312 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3313 move the check for disabled transitions to an aver since conflict
3314 resolution hasn't happened yet.
3315
3316 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3317 labels a state as inconsistent just because it has error transitions.
3318 The original form of this check appeared in revision 1.1 of lalr.c,
3319 which was committed on 1991-12-21. Now (at least), changing the
3320 consistency label on such a state appears to have no useful effect in
3321 any of the places it is examined, which I enumerate below. The key
3322 point to understanding each item in this enumeration is that a state
3323 with an error transition is labelled consistent in the first place only
3324 if it has no rules, so the check cannot matter for states that have
3325 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3326 to try to identify its conflicts, and a state must have *rules* to have
3327 conflicts. (2) Labelling a state as inconsistent will affect how
3328 action_row sets the default *rule* for the state. (3) Labelling a
3329 state as inconsistent will cause build_relations to add lookback edges
3330 to *rules* in that state.
3331 * src/state.h (struct state): Word the comment for member consistent
3332 more carefully.
3333
3334 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
3335
3336 Don't depend on C99 features.
3337 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
3338 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
3339 * src/reader.c (check_and_convert_grammar): Fix for-loop.
3340 * src/state.c (state_mark_reachable_states): Fix for-loop.
3341 (state_remove_unreachable_states): Fix for-loop.
3342
3343 Don't widen struct state with member reachable just to temporarily
3344 record reachability. Instead, use a local bitset.
3345 * src/state.h (struct state): Remove member.
3346 * src/state.c (state_new): Don't initialize it.
3347 (state_mark_reachable_states): Rename to...
3348 (state_record_reachable_states): ... this, and use bitset.
3349 (state_remove_unreachable_states): Use bitset.
3350
3351 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
3352
3353 * src/Makefile.am (yacc): Quote target action commands properly so
3354 that the yacc script isn't corrupt. Reported by Hans Aberg at
3355 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
3356
3357 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
3358 the case of pure parsers. Reported by Frans Englich at
3359 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3360 * THANKS: Add Frans Englich.
3361
3362 * NEWS (2.3a+): In the %code entry, reference section `Bison
3363 Declaration Summary' from the manual now since the %code summary has
3364 moved there.
3365 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3366 in the rules section must be terminated by semicolons.
3367
3368 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3369
3370 Extend the front-end API for %define variables to more completely
3371 mirror the back-end. This will be useful in the future.
3372 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3373 Update comments to mention the new front-end counterparts of these
3374 macros.
3375 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

3383 implementation more closely.
3384 (muscle_percent_define_invalid_value): New function.
3385 * src/muscle_tab.h (muscle_percent_define_get,
3386 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
3387 Prototype.
3388
3389 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
3390
3391 * NEWS (2.3a+): Mention yesterday's state-removal change.
3392 (2.3a): Remove the %language entry, which was added after 2.3a.
3393 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
3394 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
3395 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
3396 tests/existing.at: Update copyright date.
3397
3398 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3399
3400 If conflict resolution makes states unreachable, remove those states,
3401 report rules that are then unused, and don't report conflicts in those
3402 states.
3403 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
3404 New global function.
3405 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global
3406 function.

3410 false.
3411 (state_mark_reachable_states): New static function.
3412 (state_remove_unreachable_states): New global function.
3413 * src/state.h (struct state): Add member bool reachable.
3414 (state_remove_unreachable_states): Prototype.
3415 * tests/conflicts.at (Unreachable States After Conflict Resolution):
3416 New test case.
3417 * tests/existing.at (GNU pic Grammar): Update test case output now that
3418 an unused rule is discovered.
3419
3420 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3421
3422 Minor code cleanup in parser table construction.
3423 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
3424 (new_itemsets, save_reductions): Update for rename to nitemset.
3425 * src/closure.c (nritemset): Rename to...

3427 used in the comments.
3428 (closure): Update for rename.
3429 * src/closure.h (nritemset): Update extern to...
3430 (nitemset): ... this.

3435
3436 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
3437
3438 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
3439 still sticks to ASCII. Sorry!
3440
3441 * README-hacking: New file, taken mostly from coreutils, with changes
3442 for Bison. Contains much of the contents of:
3443 * README-cvs: Remove.
3444 * bootstrap: Sync from gnulib.

3492 DJGPP spefic issue. Inhibit the use of disallowed characters for
3493 file name genertion on Win98, WinXP, etc. These are |<>":?*\
3494 and concern testsuite case 46.

3496 * djgpp/testsuite.sed: Inhibit the use of disallowed characters.
3497 * djgpp/config.bat: Inhibit the use of disallowed characters.
3498
3499 2007-03-02 Joel E. Denny <jdenny@ces.clemson.edu>

3508 functions/macros.
3509 * src/muscle_tab.h (muscle_percent_define_insert,
3510 muscle_percent_code_grow): Prototype.
3511 * src/parse-gram.y (prologue_declaration): Use
3512 muscle_percent_define_insert and muscle_percent_code_grow when parsing
3513 %define and %code directives.
3514
3515 Make it easy to share %define boolean variables between the front-end
3516 and back-end. Though not used yet, this will be useful in the future.
3517 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
3518 Bison uses of names rather than just skeleton uses of names.
3519 (b4_percent_define_get, b4_percent_define_ifdef): Rename

3528 b4_percent_define_flag_if and b4_percent_define_default.
3529
3530 For %define variables, report locations for invalid values and
3531 redefinitions.
3532 * data/bison.m4 (b4_percent_define_flag_if): Read
3533 b4_percent_define_loc(VARIABLE) to report the location of an invalid
3534 value for VARIABLE.
3535 (b4_percent_define_default): Save a special location in
3536 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
3537 must later be reported as invalid.
3538 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
3539 functions.
3540 (muscle_percent_define_insert): Record the location of VARIABLE in
3541 muscle percent_define_loc(VARIABLE), and use it to report the previous
3542 location for a redefinition.
3543 (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
3544 (muscle_percent_define_default): Update like b4_percent_define_default.
3545 (muscle_grow_user_name_list): Rename to...
3546 (muscle_user_name_list_grow): ... this for consistency and use
3547 muscle_location_grow.
3548 * src/muscle_tab.h (muscle_location_grow): Prototype.
3549 * tests/input.at (%define errors): Update expected output.
3550 * tests/skeletons.at (%define boolean variables: invalid skeleton
3551 defaults): New test case.
3552
3553 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
3554
3555 * src/print.c (lookahead_set, state_default_rule): Remove.
3556 (print_reductions): Replace state_default_rule invocation with
3557 equivalent use of yydefact, which was computed in token_actions in
3558 tables.c.
3559 (print_results): Don't allocate lookahead_set.
3560
3561 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
3562
3563 * data/lalr1.java: Prefix all private members with yy.
3564
3565 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
3566
3567 Use YYFPRINTF instead of fprintf where appropriate. Reported by
3568 Sebastien Fricker at
3569 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
3570 * THANKS: Add Sebastien Fricker.
3571 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
3572 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must
3573 accept a variable number of arguments.
3574
3575 2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
3576
3577 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.
3578
3579 2007-02-13 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3580
3581 * djgpp/config.bat: Adjustments concerning the use of autoconf 2.61.
3582 * djgpp/config.sed: Adjustments concerning the use of autoconf 2.61.
3583 * djgpp/config.site: Adjustments concerning the use of autoconf 2.61.
3584
3585 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
3586
3587 Undo my 2007-02-07 change, switching back to the c-strcase module
3588 introduced in the 2007-02-03 change. Bruno Haible reported that
3589 the 2007-02-07 change would be dangerous in Turkish if we add a
3590 language whose name contains "i", since "i" is not lowercase "I"
3591 in Turkish.
3592 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
3593 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
3594 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
3595 * m4/.cvsignore: Remove strcase.m4.
3596 * src/getargs.c: Revert 2007-02-07 change, as follows.
3597 Include c-strcase.h.
3598 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
3599
3600 2007-02-11 Bruno Haible <bruno@clisp.org>
3601
3602 Enable the Java related testsuite tests when the only Java compiler
3603 found is a gcj < 4.3. Discussed at
3604 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
3605 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
3606
3607 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
3608
3609 * data/Makefile.am: Update copyright date.
3610 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
3611 yypstate_new returns NULL.
3612 (yypstate_new): Return NULL if malloc does.
3613 * src/reader.c (packgram): Move translation of rule actions from the
3614 beginning of packgram to...
3615 (check_and_convert_grammar): ... here right before packgram is invoked
3616 so it's easier to write more complete comments, and remove redundant
3617 code.
3618
3619 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
3620
3621 As in semantic actions, make @$ in %initial-action, %destructor, and
3622 %printer imply %locations.
3623 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
3624 scanning @$.
3625 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
3626 (@$ in %initial-action implies %locations,
3627 @$ in %destructor implies %locations,
3628 @$ in %printer implies %locations): ... these new test cases.
3629
3630 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3631
3632 Undo most of the 2007-02-03 change, switching to the strcase module
3633 now that gnulib strcase has been fixed.
3634 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
3635 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
3636 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
3637 * m4/.cvsignore: Add strcase.m4.
3638 * src/getargs.c: Revert 2007-02-03 change, as follows.
3639 Don't include c-strcase.h.
3640 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
3641 strcasecmp has "unspecified behavior" outside the POSIX locale,
3642 but it works fine in practice if at least one argument is ASCII,
3643 as is the case in Bison.
3644
3645 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
3646
3647 * tests/java.at: Skip tests if only one of javac/java is present.
3648 Reported by Joel E. Denny.
3649 * tests/atlocal.in: Adjust copyright years.
3650
3651 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
3652
3653 * data/lalr1.java (Stack): Work around old verifiers that disallow
3654 access to the private fields of an inner class, from the outer class.
3655 We can make Stack's fields public because user code doesn't have access
3656 to the instance of Stack used by parse(). Reported by Paul Eggert.
3657
3658 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3659
3660 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
3661 the right spot for these files?
3662 * bootstrap.conf (gnulib_modules): Add c-strcase.
3663 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
3664 c-strncasecmp.c.
3665 * src/getargs.c: Include c-strcase.h.
3666 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
3667 to avoid unspecified behavior.
3668
3669 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
3670
3671 * doc/bison.texinfo (Decl Summary): Correct typo.
3672
3673 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
3674
3675 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
3676 Complain if the value does not match empty, "true" or "false".
3677 * data/c++.m4: Adjust default definitions of %define variables.
3678 * data/java.m4: Adjust default definitions of %define variables.
3679 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
3680 to above behavior.
3681 * tests/input.at (Boolean %define variables): Test new behavior.
3682
3683 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
3684
3685 * NEWS: Mention java.
3686 * TODO: Remove things that are done.
3687 * bootstrap.conf: Add javacomp-script and javaexec-script.
3688 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
3689
3690 * data/Makefile.am: Add new files.
3691 * data/java-skel.m4: New.
3692 * data/java.m4: New.
3693 * data/lalr1.java: New.
3694
3695 * doc/bison.texinfo: Put "A Complete C++ Example" under
3696 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
3697 under Other Languages.
3698
3699 * src/getargs.c (valid_languages): Add Java.
3700 * src/getargs.h (struct bison_language): Update size of string fields.
3701
3702 * tests/Makefile.am: Add java.at.
3703 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
3704 * tests/java.at: New.
3705 * tests/testsuite.at: Include it.
3706
3707 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
3708
3709 Clean up.
3710 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
3711 at_directive_argv arguments so these no longer have to be global
3712 variables. Also, update the implementation for the following changes.
3713 (fail_for_at_directive_too_many_args,
3714 fail_for_at_directive_too_few_args): Add at_directive_name argument.
3715 (at_directive_name): Remove as at_directive_argv[0] will be used for
3716 this now.
3717 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
3718 for the directive name.
3719 (at_directive_argc, at_directive_argv): Make these local within
3720 skel_lex instead of global.
3721 (INITIAL): Update directive start action for above changes.
3722 (SC_AT_DIRECTIVE_ARG): Rename to...
3723 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
3724 (SC_AT_DIRECTIVE_SKIP_WS): Update.
3725 (scan_skel): Move yylex_destroy to...
3726 (skel_scanner_free): ... here.
3727 * tests/skeletons.at (installed skeleton file name): Rename to...
3728 (installed skeleton file names): ... this.
3729
3730 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
3731
3732 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3733 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
3734 Summary" not "Directives".
3735 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
3736 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
3737 since the former is now the more complete one.
3738 (Prologue Alternatives): Likewise and do the same for %defines.
3739 (Table of Symbols): Add summary of %code, add summary of %define, and
3740 move full %code documentation to...
3741 (Decl Summary): ... here for consistency with other entries in these
3742 sections.
3743 Move %define entry in order to keep this list alphabetized.
3744 Reword %define entry a little to put less emphasis on the skeleton
3745 concept, which most users shouldn't have to think about.
3746
3747 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
3748
3749 Adjust to recent gnulib changes.
3750 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
3751 Add string.h, string_.h, unistd_.h, wchar_.h.
3752 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
3753 * src/system.h: Don't include <stpcpy.h>; this is now done by
3754 <string.h>.
3755
3756 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
3757
3758 Simplify implementation of unqualified %code, implement macros for
3759 uniform treatment of boolean %define flags. Document %define.
3760 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
3761 b4_percent_code_ifdef): New.
3762 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
3763 * data/c++.m4: Define default value for global_tokens_and_yystype.
3764 * data/glr.cc: Likewise.
3765 * data/location.cc: Use b4_percent_define_flag_if.
3766
3767 * doc/bison.texinfo (Decl Summary): Document %define.
3768
3769 * src/parse-gram.y (Unqualified %code): Change muscle name to
3770 b4_percent_code().
3771 (content.opt): Default to empty.
3772
3773 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
3774
3775 Implement support for relative and absolute skeleton file names.
3776 Discussed starting at
3777 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
3778 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
3779 (Bison Options): Document in --skeleton entry.
3780 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
3781 full_skeleton can't necessarily hold all of pkgdatadir.
3782 If the specified skeleton file name contains a `/', don't prepend
3783 pkgdatadir.
3784 * src/parse-gram.y (prologue_declaration): If the specified skeleton
3785 file name contains a `/', prepend the grammar file directory.
3786 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
3787 * skeletons.at: New file.
3788 (relative skeleton file names): New test case.
3789 (installed skeleton file names): New test case.
3790 * tests/testsuite.at: Include skeletons.at.
3791
3792 * bootstrap: Update copyright to 2007.
3793
3794 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
3795
3796 * bootstrap: Remove occurrences of .#bootmp from the files.
3797
3798 2007-01-17 Akim Demaille <akim@epita.fr>
3799
3800 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
3801 nonterminals.
3802 Use per-type %printer.
3803
3804 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
3805
3806 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,
3807 data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,

3813
3814 2007-01-16 Akim Demaille <akim@epita.fr>
3815
3816 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
3817 error code.
3818 (Calc++ Scanner): Exit with failure if we can't open the input
3819 file.
3820 Accept "-" standing for stdin.
3821 (Calc++ Top Level): Print the result only if the parsing was
3822 successful.
3823
3824 2007-01-16 Akim Demaille <akim@epita.fr>
3825
3826 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
3827
3828 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
3829 and Joel E. Denny <jdenny@ces.clemson.edu>
3830
3831 Clean up %define and %code implementation in M4 some. Most
3832 importantly, rename all related macros to be in the b4_percent_define
3833 and b4_percent_code namespaces. Also, complete support for `.' in
3834 %define variable names and %code qualifiers.
3835 * data/bison.m4 (b4_check_user_names): Check for special
3836 "SKELETON-NAMESPACE(name)" macros instead of using two nested
3837 m4_foreach loops.
3838 (b4_get_percent_define, b4_get_percent_code): Rename to...
3839 (b4_percent_define_get, b4_percent_code_get): ... these.
3840 Extend documentation with examples.
3841 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
3842 b4_percent_define_skeleton_variables and
3843 b4_percent_code_skeleton_qualifiers.
3844 Expect any value for the %define variable `foo' to be stored in the
3845 macro named `b4_percent_define(foo)'; expect any %code blocks for the
3846 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
3847 expect any unqualified %code blocks to be stored in a macro named
3848 `b4_percent_code_unqualified'.
3849 Use m4_indir so that %define variable names and %code qualifiers can
3850 contain `.', which is allowed by the grammar parser.
3851 (b4_percent_define_default): New macro to set a default value for a
3852 %define variable.
3853 (m4_wrap): Update wrapped code, and fix some underquoting.
3854 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
3855 Expect grammar uses of %define variables and %code qualifiers to be
3856 defined in b4_percent_define_user_variables and
3857 b4_percent_code_user_qualifiers.
3858 * data/c++.m4: Use b4_percent_define_default rather than
3859 m4_define_default. Fix some underquoting. Skeleton usage of %define
3860 variable define_location_comparison now implies skeleton usage of
3861 %define variable filename_type.
3862 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3863 data/push.c, data/yacc.c: Update macro names.
3864 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
3865 muscle names.
3866
3867 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3868
3869 DJGPP specific issues.
3870
3871 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
3872 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
3873
3874 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3875
3876 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
3877 run parsers in all tests so that Valgrind is invoked during
3878 maintainer-check-valgrind.
3879 (Duplicate representation of merged trees): Free all semantic values.
3880 (Duplicated user destructor for lookahead): Likewise.
3881
3882 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3883
3884 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
3885 command-line prefix.
3886 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
3887 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
3888 miss Valgrind messages.
3889 (Exploding the Stack Size with Malloc): Likewise.
3890
3891 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3892
3893 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
3894 locals. Reported by Juan Manuel Guerrero at
3895 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
3896 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
3897 Fix some indentation also.
3898 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
3899 explaining this issue.
3900
3901 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
3902 and Joel E. Denny <jdenny@ces.clemson.edu>
3903
3904 Simplify union and prologue handling, and escape union and lex/parse
3905 params with digraphs.
3906 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
3907 values to the empty string since these are no longer guaranteed
3908 initialized by the front-end.
3909 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
3910 braces around b4_user_stype since this is no longer done by the
3911 front-end.
3912 * src/files.c, src/files.h (pre_prologue_obstack,
3913 post_prologue_obstack): Remove.
3914 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
3915 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
3916 with digraphs. This fixes lex params and parse params.
3917 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
3918 * src/output.c (prepare): Remove muscle insertion of the prologues.
3919 (output): Remove freeing of pre_prologue_obstack and
3920 post_prologue_obstack.
3921 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
3922 than prologue_augment for prologue parsing so you don't need prologue
3923 obstacks.
3924 (grammar_declaration): For %union RHS, use `braceless' instead of
3925 "{...}" so that braces are already stripped and code is escaped with
3926 digraphs.
3927 * src/reader.c (prologue_augment): Remove.
3928 (reader): Remove initialization of pre_prologue_obstack and
3929 post_prologue_obstack.
3930 * src/reader.h (prologue_augment): Remove.
3931
3932 * data/c.m4: Remove stray parenthesis.
3933
3934 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3935
3936 Remove quotes from variables names in %define directives and from
3937 qualifiers in %code directives, and restrict the characters that are
3938 allowed in them to M4-friendly ones. For %define, continue to support
3939 the quoted form as a deprecated feature. Discussed starting at
3940 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
3941 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
3942 %code.
3943 * doc/bison.texinfo (Prologue Alternatives): Update.
3944 (Decl Summary): In %defines entry, update mention of `%code requires'
3945 and `%code provides'.
3946 (C++ Location Values): Update %define uses.
3947 (Calc++ Parser Interface): Likewise.
3948 (Calc++ Parser): Likewise, and update `%code requires' uses.
3949 (Table of Symbols): Update %code documentation.
3950 * src/parse-gram.y (prologue_declaration): For %define variables, use
3951 `variable' instead of `STRING'.
3952 (grammar_declaration): For %code qualifiers, use `ID' instead of
3953 `STRING'.
3954 (variable): New nonterminal that takes an `ID' or a `STRING'.
3955 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
3956 and %define uses.
3957 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
3958 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
3959 (%define errors): Update %define uses.

3963 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
3964 instead of muscle_insert for %define values so that M4-special
3965 characters are replaced with digraphs.
3966 * tests/input.at (%define errors): Extend to check weird values.
3967
3968 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3969
3970 Instead of having skeletons declare all valid %define variables and
3971 %code qualifiers, provide macros that retrieve the associated values
3972 and build these lists automatically. Thus Bison will now warn when a
3973 variable or qualifier is not used by the skeleton in the current
3974 invocation regardless of whether it might sometimes be used by that
3975 skeleton in other invocations. Also, move all %define value macros to
3976 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3977 form, which is replaced by %code.
3978 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3979 (b4_check_user_names): ... this, and change the series of valid name
3980 arguments to a single list argument for names used in the skeleton
3981 similar to the existing list argument for names used in the grammar.
3982 Warn instead of complaining.
3983 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3984 values and %code code, to format %code code properly, and to build
3985 lists of all %define variables and %code qualifiers used in the
3986 skeleton: b4_skeleton_percent_define_variables and
3987 b4_skeleton_percent_code_qualifiers.
3988 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
3989 Remove, and...
3990 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
3991 the skeleton names lists can finish building first. In place of
3992 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3993 expect the lists b4_user_percent_define_variables and
3994 b4_user_percent_code_qualifiers.
3995 * data/c++.m4: Where setting default values for b4_parser_class_name,
3996 b4_location_type, b4_filename_type, b4_namespace, and
3997 b4_define_location_comparison, update their names to the
3998 b4_percent_define_ namespace.
3999 * data/glr.c: Don't use b4_check_percent_define_variables and
4000 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4001 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
4002 (b4_parser_class_name, b4_namespace): Define these using
4003 b4_get_percent_define for parser_class_name and namespace.
4004 * data/location.cc: Use b4_get_percent_define.
4005 * data/push.c: Don't use b4_check_percent_define_variables and
4006 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4007 * data/yacc.c: Likewise, and don't call m4_exit in
4008 b4_use_push_for_pull_if or m4_wrap code will never execute.
4009 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
4010 Rename to...
4011 (muscle_grow_user_name_list): ... this for consistency with the
4012 terminology used in bison.m4.
4013 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
4014 %define variable names, and rename muscle used_percent_define_variables
4015 to user_percent_define_variables.
4016 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
4017 user_percent_code_qualifiers.
4018 (content): Remove.
4019 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
4020 {CODE} form is no longer accepted.
4021 * tests/input.at (Reject bad %code qualifiers): Rename to...
4022 (Reject unused %code qualifiers): ... this, and update test output.
4023 (%define error): Update test output.
4024
4025 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
4026
4027 Check for unrecognized %define variables similar to checking for
4028 unrecognized %code qualifiers. Check for redefined %define variables.
4029 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
4030 generalizes...
4031 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
4032 (b4_check_percent_define_variables): New, also wraps it.
4033 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
4034 variables using b4_check_percent_define_variables.
4035 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
4036 all those exercised in the test suite and all those listed in the
4037 `Default values' section of c++.m4. Are there others?
4038 * data/push.c, data/yacc.c: Declare no valid %define variables.
4039 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
4040 similar to muscle_find, but it works even when the muscle stores a
4041 const value.
4042 (muscle_grow_used_name_list): New function for constructing the used
4043 name list muscles that b4_check_for_unrecognized_names requires.
4044 * src/parse-gram.y (prologue_declaration): Warn if a variable is
4045 %define'd more than once. Define the b4_used_percent_define_variables
4046 muscle with muscle_grow_used_name_list.
4047 (grammar_declaration): Abbreviate %code code with
4048 muscle_grow_used_name_list.
4049 * tests/input.at (%define errors): New.
4050
4051 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4052
4053 Provide warn_at, complain_at, and fatal_at function callbacks to the
4054 skeletons, and use this for %code qualifier complaints.
4055 * data/bison.m4 (b4_error_at): New, invoked by...
4056 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
4057 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
4058 @fatal_at(...@) directives.
4059 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
4060 qualifiers in b4_used_percent_code_qualifiers and to use
4061 b4_complain_at.
4062 * src/location.c, src/location.h (boundary_set_from_string): New global
4063 function.
4064 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
4065 function.
4066 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
4067 to b4_used_percent_code_qualifiers.
4068 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
4069 function.
4070 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
4071 (lineno): Rename to...
4072 (out_lineno): ... this so I don't misunderstand it again.
4073 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
4074 here; these newlines are in the input but not the output file.
4075 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
4076 (at_directive_perform): ... this new static function, and add handling
4077 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
4078 directives.
4079 * tests/input.at (Reject bad %code qualifiers): Update test output with
4080 locations and extend.
4081
4082 * tests/output.at (Output file name: [, Output file name: ]): Remove
4083 bogus comment about these tests failing.
4084
4085 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4086
4087 Clean up b4_check_percent_code_qualifiers a little.
4088 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
4089 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
4090 documentation and add examples.
4091 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
4092 qualifiers here.
4093
4094 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
4095
4096 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4097 unreliable -- especially when they're hidden inside another macro.
4098 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
4099 data/c.m4: Remove m4_divert(-1).
4100 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4101 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
4102 m4_divert_push(0) and m4_divert_pop(0).
4103 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
4104 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
4105 pushed and popped by m4sugar, should be first on the stack.
4106
4107 Provide warn, complain, and fatal function callbacks to the skeletons.
4108 This provides more flexibility than m4_fatal, improves the error
4109 message format, and captures messages for translation. Discussed
4110 starting at
4111 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
4112 * data/bison.m4 (b4_error): New, invoked by...
4113 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
4114 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
4115 directives. Because these M4 macros might be called when the current
4116 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
4117 the previous removal of uses of m4_divert, which caused trouble.
4118 (b4_check_percent_code_qualifiers): Use b4_complain instead of
4119 m4_fatal to report unrecognized %code qualifiers.
4120 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
4121 push parser requests.
4122 * data/glr.c: Use b4_complain instead of m4_fatal to report
4123 non-deterministic push parser requests.
4124 Update @output usage to @output(...@) form.
4125 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
4126 report missing %defines. Update @output usage to @output(...@) form.
4127 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
4128 @output(...@) form.
4129 * src/main.c (main): Invoke skel_scanner_free.
4130 * src/scan-skel.h (skel_scanner_free): Prototype new function.
4131 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
4132 obstack_for_string from flex-scanner.h.
4133 (YY_DECL): Use to declare skel_lex static.
4134 (decode_at_digraphs): Remove; now handled in the new
4135 SC_AT_DIRECTIVE_ARG start condition.
4136 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
4137 functions.
4138 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
4139 at_directive_argv): New static globals.
4140 (INITIAL): Use fail_for_invalid_at.
4141 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
4142 recognize the start of a generalized `@directive(...@)' form and
4143 start...
4144 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
4145 directive args (using the new obstack_for_string), to decode the
4146 contained @ diagraphs, and to perform the directive. It recognizes
4147 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
4148 @output(...@).
4149 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
4150 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
4151 `@,'.
4152 (scan_skel): Initialize obstack_for_string on the first call.
4153 (skel_scanner_free): New function to free obstack_for_string.
4154 * tests/input.at (Reject bad %code qualifiers): Update test output.
4155
4156 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
4157
4158 Consolidate the 4 prologue alternative directives (%code, %requires,
4159 %provides, and %code-top) into a single %code directive with an
4160 optional qualifier field. Discussed at
4161 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
4162 * NEWS (2.3a+): Rewrite the existing entry for the prologue
4163 alternatives.
4164 * doc/bison.texinfo (Prologue Alternatives): Update.
4165 (Decl Summary): Update to %code "requires" and %code "provides".
4166 (Calc++ Parser): Update to %code "requires".
4167 (Table of Symbols): Remove entries for %requires, %provides, and
4168 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
4169 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
4170 are replaced by b4_percent_code_provides and b4_percent_code_requires,
4171 which are skeleton-specific.
4172 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
4173 declare what %code qualifiers it supports and to complain if any other
4174 qualifiers were used in the grammar.
4175 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
4176 and b4_user_code([b4_percent_code_provides]) in place of
4177 b4_user_requires and b4_user_provides.
4178 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
4179 Add b4_user_code([b4_percent_code_top]) and
4180 b4_user_code([b4_percent_code]).
4181 Invoke b4_check_percent_code_qualifiers.
4182 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4183 PERCENT_REQUIRES): Remove.
4184 (grammar_declaration): Remove RHS's for %code-top, %provides, and
4185 %requires. Rewrite the %code RHS as the unqualified form defining the
4186 muscle b4_percent_code. Add another RHS for the qualified %code form,
4187 which defines muscles of the form b4_percent_code_QUALIFIER and the
4188 b4_used_percent_code_qualifiers muscle.
4189 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4190 PERCENT_REQUIRES): Remove.
4191 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
4192 %code "requires" and %code "provides".
4193 * tests/input.at (Reject bad %code qualifiers): New.
4194
4195 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4196
4197 Use the new code_props interface for destructors and printers.
4198 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
4199 printer_location members, and change the type of the destructor and
4200 printer members to code_props.
4201 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
4202 symbol_printer_get, semantic_type_destructor_set,
4203 semantic_type_printer_set, default_tagged_destructor_set,
4204 default_tagless_destructor_set, default_tagged_printer_set,
4205 default_tagless_printer_set): Use code_props in arguments and return
4206 types in place of char const * and location.
4207 (symbol_destructor_location_get, symbol_printer_location_get): Remove
4208 since the locations are now contained in the return of
4209 symbol_destructor_get and symbol_printer_get.
4210 * src/output.c (symbol_destructors_output, symbol_printers_output):
4211 Replace with...
4212 (symbol_code_props_output): ... this to eliminate duplicate code.
4213 (output_skeleton): Update to use symbol_code_props_output.
4214 * src/reader.c (symbol_should_be_used): Update use of
4215 symbol_destructor_get.
4216 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4217 Update uses of the various _destructor_set and _printer_set functions.
4218 * src/symtab.c: (default_tagged_destructor_location,
4219 default_tagless_destructor_location, default_tagged_printer_location,
4220 default_tagless_printer_location): Remove since we...
4221 (default_tagged_destructor, default_tagless_destructor,
4222 default_tagged_printer, default_tagless_printer): ... change the type
4223 of these to code_props.
4224 (symbol_new, semantic_type_new, symbol_destructor_set,
4225 semantic_type_destructor_set, symbol_destructor_get,
4226 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
4227 symbol_check_alias_consistency, default_tagged_destructor_set,
4228 default_tagless_destructor_set, default_tagged_printer_set,
4229 default_tagless_printer_set): Update.
4230 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4231 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4232 code_props members.
4233 (symbol_print): Use SYMBOL_CODE_PRINT.
4234
4235 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4236
4237 Use the new code_props interface for rule actions.
4238 * src/symlist.h (symbol_list): Replace action, action_location, and
4239 used members with a code_props action_props member.
4240 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4241 grammar_midrule_action, grammar_current_rule_merge_set,
4242 grammar_current_rule_symbol_append, packgram): Update.
4243 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4244 * src/scan-code.l (handle_action_dollar): Update.
4245 (translate_rule_action): Remove, no longer used.
4246 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4247
4248 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4249
4250 Use the new code_props interface in parse-gram.y.
4251 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
4252 Update all uses of translate_* functions to use the new code_props
4253 interface and to use gram_scanner_last_string_free and
4254 code_scanner_last_string_free where possible.
4255 (grammar_declaration): symbol_list_destructor_set and
4256 symbol_list_printer_set now perform the translation, so don't do it
4257 here. Use gram_scanner_last_string_free where possible.
4258 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
4259 translate_code): Remove, no longer used.
4260 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
4261 symbol_list_printer_set): Perform code translation here rather than
4262 depending on the caller to do so.
4263
4264 * src/symlist.h (struct symbol_list): Correct some documentation typos.
4265 * src/scan-gram.h (gram_last_string): Remove declaration.
4266 * src/scan-gram.l (last_string): Declare it static.
4267
4268 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4269
4270 Encapsulate code properties and related functionality for the various
4271 destructors, printers, and actions into a code_props structure and
4272 interface. This patch merely implements code_props in scan-code.h and
4273 scan-code.l. Future patches will rewrite other modules to use it.
4274 Discussed starting at
4275 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4276 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4277 consistently initialize const structs that have an empty location
4278 field.
4279 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4280 to ensure consistency.
4281 * src/scan-code.h (code_props): New structure.
4282 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4283 function, macro, and const global variable for initializing a
4284 code_props with no code.
4285 (code_props_plain_init, code_props_symbol_action_init,
4286 code_props_rule_action_init, code_props_translate_code): The rest of
4287 the new code_props functional interface. Among other things, the init
4288 functions set the code_props kind field so that
4289 code_props_translate_code will know whether to behave like
4290 translate_symbol_action, translate_rule_action, or translate_code.
4291 These old translate functions must remain until all other modules are
4292 updated to use the new code_props interface.
4293 (code_scanner_last_string_free): New function similar to
4294 gram_scanner_last_string_free.
4295 (code_scanner_free): Add documentation.
4296 * src/scan-code.l: Implement the new interface.
4297 (code_lex): Make it static, add a code_props* argument, and remove the
4298 rule argument.
4299 (last_string): New static global similar to the one in scan-gram.l.
4300 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4301 instead of rule.
4302 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4303 code_props since Bison may one day use this information for destructors
4304 and printers.
4305 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4306 (handle_action_dollar): Use symbol_list_n_get and set used flag
4307 directly since symbol_list_n_used_set is removed.
4308 (translate_action): Add a code_props* argument and remove the rule,
4309 action, and location arguments. Pass the code_props* on to code_lex.
4310 (translate_rule_action, translate_symbol_action, translate_code):
4311 Rewrite as wrappers around the new code_props interface.
4312 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
4313 it would eventually need to break the encapsulation of code_props.
4314
4315 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4316
4317 * etc/.cvsignore: New.
4318
4319 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4320
4321 Add maintainer-push-check to run maintainer-check using push parsing in
4322 place of pull parsing where available.
4323 * Makefile.am (maintainer-push-check): New.
4324 * data/bison.m4 (b4_use_push_for_pull_if): New.
4325 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
4326 appropriately based on their existing values.
4327 (yypush_parse): Don't print push-parser-specific diagnostics if push
4328 parsing is being used in place of pull parsing.
4329 * data/yacc.c: If push parsing should replace pull parsing, redirect to
4330 push.c.
4331 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
4332 variable, and insert b4_use_push_for_pull_flag into muscles.
4333 * tests/Makefile.am (maintainer-push-check): New.
4334

4337 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
4338 (whether successful or failed) so that yypush_parse can be invoked
4339 again to start a new parse using the same yypstate.
4340 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
4341 check multiple yypull_parse invocations on the same yypstate. For pull
4342 mode, extend to check multiple yyparse invocations.
4343 (Exploding the Stack Size with Alloca): Extend to try with
4344 %push-pull-parser.
4345 (Exploding the Stack Size with Malloc): Likewise.
4346
4347 * tests/calc.at (Simple LALR Calculator): Don't specify
4348 %skeleton "push.c" since %push-pull-parser implies that now.
4349 * tests/headers.at (export YYLTYPE): Don't check for the push
4350 declarations. Otherwise, this test case can't be used to see if push
4351 mode can truly emulate pull mode.
4352 * tests/input.at (Torturing the Scanner): Likewise.
4353 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
4354 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
4355 AT_YACC_IF, which now includes the case of push mode since %skeleton
4356 need not be used for push mode. This will be more intuitive once
4357 push.c is renamed to yacc.c.
4358
4359 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4360
4361 For push mode, convert yyparse from a macro to a function, invoke yylex
4362 instead of passing a yylexp argument to yypull_parse, and don't
4363 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4364 Discussed starting at
4365 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4366 * data/bison.m4 (b4_pull_if): New.
4367 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4368 * data/push.c: Improve M4 quoting a little.
4369 (b4_generate_macro_args, b4_parenthesize): Remove.
4370 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4371 any time a pull parser is requested.
4372 Don't #define this as a wrapper around yypull_parse. Instead, when
4373 both push and pull are requested, make it a function that does that
4374 same thing.
4375 (yypull_parse): If there's a b4_prefix, #define this to
4376 b4_prefix[pull_parse] when both push and pull are requested.
4377 Don't define this as a function unless both push and pull are
4378 requested.
4379 Remove the yylexp argument and hard-code yylex invocation instead.
4380 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4381 %push-parser.
4382 * src/getargs.c (pull_parser): New global initialized to true.
4383 * getargs.h (pull_parser): extern it.
4384 * src/output.c (prepare): Insert pull_flag muscle.
4385 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4386 (prologue_declaration): Set both push_parser and pull_parser = true for
4387 %push-pull-parser. Set push_parser = true and pull_parser = false for
4388 %push-parser.
4389 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4390 %push-parser since there's no backward-compatibility concern here.
4391 Scan %push-pull-parser.
4392 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4393 instead of %push-parser.
4394 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4395 prototype it in the module that calls yyparse.
4396 * tests/input.at (Torturing the Scanner): Likewise.
4397 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4398
4399 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4400
4401 Update etc/bench.pl. Optimize push mode a little (the yyn change
4402 deserves most of the credit).
4403 * Makefile.am (SUBDIRS): Add etc subdirectory.
4404 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4405 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4406 yytoken, yyval, and yyloc declarations to...
4407 (yyparse or yypush_parse): ... here to improve performance. For
4408 yypush_parse invocations after the first, be sure to assign yyn its old
4409 value again.
4410 (yypstate_new): Don't bother initializing the yyresult field since the
4411 initial value isn't used.
4412 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4413 remove the #define that, in push mode, set it to yyps->NAME.
4414 * etc/Makefile.am: New.
4415 * etc/bench.pl: Remove and build it instead from...
4416 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4417 "tests/bison" from the build directory by default rather than just
4418 invoking "bison" from $PATH.
4419 (calc_grammar): Update push parser code: don't declare yylval globally,
4420 don't define yyparse_wrapper, and don't #define yyparse.
4421 (bench_grammar): Update to check all working combinations of yacc.c,
4422 push.c, impure, pure, pull, and push.
4423
4424 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4425
4426 For push mode, add pull wrappers around yypush_parse.
4427 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4428 (yypull_parse): New function wrapping yypush_parse.
4429 (yyparse): New #define wrapping yypull_parse.
4430 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4431 is declared.
4432 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4433 prototype yylex in the module that calls yyparse, and don't prototype
4434 yyparse there. Otherwise, the yyparse expansion won't compile.
4435 * tests/input.at (Torturing the Scanner): Likewise.
4436
4437 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4438
4439 Enable push parsers to operate in impure mode. Thus, %push-parser no
4440 longer implies %pure-parser. The point of this change is to move
4441 towards being able to test the push parser code by running the entire
4442 test suite as if %push-parser had been declared.
4443 * data/push.c (yypush_parse): For impure mode, remove the
4444 yypushed_char, yypushed_val, and yypushed_loc arguments.
4445 Instead, declare these as local variables initialized to the global
4446 yychar, yylval, and yylloc.
4447 For the first yypush_parse invocation only, restore the initial values
4448 of these global variables when it's time to read a token since they
4449 have been overwritten.
4450 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4451 %push-parser.
4452 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4453 %pure-parser along with %push-parser since this test case was designed
4454 for pure push parsers.
4455 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4456 (AT_YACC_OR_PUSH_IF): New.
4457 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4458 add a note that it's still wrong for some cases (as it has been for a
4459 while).
4460 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4461 %push-parser no longer implies %pure-parser.
4462
4463 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4464
4465 Remove some unnecessary differences between the pull parser code and
4466 the push parser code. This patch enables yynerrs in push mode.
4467 * data/push.c: Reformat M4 a little.
4468 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4469 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
4470 because push mode is on. Instead, if pure mode is on, move yynerrs
4471 to...
4472 (b4_declare_parser_state_variables): ... here.
4473 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
4474 to yyps->NAME so it can be used in yypush_parse.
4475 (yypush_parse): Don't omit uses of yynerrs in push mode.
4476
4477 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4478
4479 Fix bug such that the first pushed token's value and location are
4480 sometimes overwritten (sometimes by %initial-action) before being used.
4481 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
4482 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4483 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4484 more closely mimic the pull parser logic.
4485 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4486 time to read a token, which is after any initialization of yylval and
4487 yylloc.
4488 (gottoken): Rename label to...
4489 (yyread_pushed_token): ... for clarity and to avoid infringing on the
4490 user namespace.
4491
4492 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4493
4494 Rearrange initialization of the parser state variables so that the
4495 skeleton doesn't have to have a copy for pull mode and another for push
4496 mode. This patch also fixes at least a bug such that yylloc was not
4497 initialized (with b4_location_initial_line and
4498 b4_location_initial_column) upon calling yypush_parse. However, that
4499 initialization now overwrites the first token's location;
4500 %initial-action assigning @$ already did the same thing, and both bugs
4501 will be fixed in a later patch.
4502 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4503 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4504 yyss, yyvs, yyls, and yystacksize.
4505 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4506 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4507 yylsp.
4508 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4509 yyps->NAME so it can be used in yypush_parse.
4510 (yyparse or yypush_parse): For yypush_parse, don't print the
4511 "Starting parse" diagnostic for invocations after the first.
4512 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4513 yypush_parse, only do it for the first invocation.
4514 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4515 initialization to occur in yypush_parse but only on the first
4516 invocation.
4517
4518 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4519
4520 * data/push.c: Add CPP guards around push parser declarations in both
4521 the header and the code file.
4522 In the code file, move the push parser declarations to the same place
4523 they appear in the header file.
4524 Clean up the M4 some, especially the inconsistent underquoting in
4525 some b4_c_function_def and b4_c_function_decl uses.
4526
4527 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4528
4529 Encapsulate the push parser state variables into an M4 macro so the
4530 push skeleton doesn't have to list them again for pull mode's yyparse.
4531 For push mode, remove yypush_parse's local equivalents of these
4532 variables to eliminate unnecessary copying between the two sets at
4533 run-time. This patch also fixes at least a bug related to multiple
4534 %initial-action invocations in push mode.
4535 * data/push.c (b4_declare_parser_variables): Rename to...
4536 (b4_declare_scanner_communication_variables): ... this for clarity and
4537 update both uses.
4538 (b4_declare_yyparse_variables): Remove and move its contents to the one
4539 spot where it was invoked.
4540 (b4_declare_parser_state_variables): New macro containing the parser
4541 state variables required by push mode.
4542 (struct yypstate): Replace all fields but yynew with
4543 b4_declare_parser_state_variables.
4544 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4545 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4546 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4547 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4548 parser state variable declarations with
4549 b4_declare_parser_state_variables.
4550 Don't initialize parser state variables when calling yypush_parse since
4551 yypstate_new already does that.
4552 Invoke the user's initial action only upon the first yypush_parse
4553 invocation.
4554 Remove all code that copies between the local parser state variables
4555 and the yypstate.
4556
4557 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4558
4559 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
4560 prevent a name collision in a future patch where these names will
4561 sometimes be #define'd.
4562 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
4563 since it no longer has the same name as the existing argument.
4564 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
4565
4566 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
4567 and Joel E. Denny <jdenny@ces.clemson.edu>
4568
4569 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
4570 that the argument is case-insensitive, and there's no `=' here.
4571 For the %skeleton entry, mention that %language is better.
4572 (Bison Options): Likewise for --language and --skeleton. Move the
4573 --skeleton entry so that the `Tuning the parser' section is sorted
4574 alphabetically on long options.
4575 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
4576 %language directive in detail here; cross-reference the %language
4577 documentation instead.
4578 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
4579 `%require "2.3b"' so that the example is always up-to-date.
4580 (Table of Symbols): Add entries for %language and %skeleton.
4581 * examples/extexi (normalize): Instead of replacing every %require
4582 argument with the current Bison version, just substitute for
4583 `@value{VERSION}'. This guarantees that we're testing what actually
4584 appears in the documentation.
4585 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
4586 rather than `@VERSION@'.
4587
4588 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4589
4590 * NEWS: Reword the %language news a bit, and put it earlier.
4591
4592 * src/getargs.c (skeleton_arg): Last arg is now location const *.
4593 Rewrite to simplify the logic.
4594 (language_argmatch): Likewise.
4595 (program_name): We now own this var.
4596 * src/getargs.h (struct bison_language): Use char[] rather than
4597 const char *.
4598
4599 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
4600 Java is supported.
4601 * src/complain.c (program_name): Remove decl; no longer needed.
4602 * src/main.c (program_name): Remove; now belongs to getargs.
4603
4604 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
4605
4606 * NEWS: Document %language.
4607
4608 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
4609
4610 * data/c-skel.m4, data/c++-skel.m4: New files.
4611 * data/glr.c: Complain on push parsers.
4612
4613 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
4614 over %skeleton.
4615 (Decl Summary): Document %language and %skeleton.
4616 (Command line): Document -L.
4617
4618 * examples/extexi: Rewrite %require directive.
4619 * examples/calc++/Makefile.am: Pass VERSION to extexi.
4620
4621 * src/files.c (compute_exts_from_gc): Look in language structure
4622 for .y extension.
4623 (compute_file_name_parts): Check whether .tab should be added.
4624 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
4625 (language, skeleton_arg, language_argmatch): New.
4626 (long_options): Add --language.
4627 (getargs): Use skeleton_arg, add -L/--language.
4628 * src/getargs.h: Include location.h.
4629 (struct bison_language, language, skeleton_arg, language_argmatch): New.
4630 * src/output.c (prepare): Pick default skeleton from struct language.
4631 Don't dispatch C skeletons here.
4632 * src/parse-gram.y (PERCENT_LANGUAGE): New.
4633 (prologue_declaration): Add "%language" rule, use skeleton_arg.
4634 * src/scan-gram.l ("%language"): New rule.
4635
4636 * tests/calc.at: Test %skeleton and %language.
4637 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
4638 (AT_GLR_IF): Look for %skeleton "glr.cc".
4639 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
4640 (AT_YACC_IF): Reject %language.
4641
4642 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4643
4644 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
4645 since it wasn't used; only the typedef name 'semantic_type' is needed.
4646 Also, omit trailing white space.
4647
4648 * bootstrap: Sync from coreutils.
4649 (gnulib_extra_files): Add build-aux/announce.gen.
4650 (slurp): Adjust .gitignore files like .cvsignore files.
4651 * build-aux/announce-gen: Remove from CVS, since bootstrap
4652 now creates this.
4653
4654 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
4655
4656 Make %push-parser imply %pure-parser. This fixes several bugs; see
4657 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
4658 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
4659 pure_parser = true.
4660 * data/push.c: Don't bother testing b4_push_if when deciding whether
4661 to expand b4_declare_parser_variables globally.
4662 (yypush_parse): Likewise in here.
4663
4664 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
4665 (yy_reduce_print): Reformat M4 for readability.
4666
4667 2006-12-15 Bob Rossi <bob@brasko.net>
4668 and Joel Denny <jdenny@ces.clemson.edu>
4669
4670 * data/push.c (yypstate): Add typedef, and update all uses of
4671 struct yypstate to just yypstate.
4672 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
4673
4674 2006-12-14 Bob Rossi <bob@brasko.net>
4675
4676 * data/push.c (yypush_parse): Declare prototype regardless of
4677 %locations option.
4678
4679 2006-12-14 Bob Rossi <bob@brasko.net>
4680
4681 * data/push.c (yyparse): Remove the prototype and the #define when in
4682 push-parser mode.
4683
4684 2006-12-13 Bob Rossi <bob@brasko.net>
4685
4686 * data/push.c (yypstate_init): Rename to...
4687 (yypstate_new): ... this and use b4_c_function_def.
4688 (yypstate_delete): New.
4689 (yypush_parse): Change parameters yynval and yynlloc to be const.
4690 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
4691 yypstate_delete functions.
4692
4693 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
4694
4695 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
4696 strange test case titles. Reported by Bob Rossi.
4697
4698 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
4699
4700 * TODO: Add pointer to Sylvain Schmitz's work on static detection
4701 of potential ambiguities in GLR grammers.
4702
4703 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
4704
4705 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
4706 `bison ', use m4_index instead of m4_substr since chopping up a string
4707 containing M4-special characters causes problems here.
4708
4709 Fix a couple of bugs related to special characters in user-specified
4710 file names, and make it easier for skeletons to compute output file
4711 names with the same file name prefix as Bison-computed output file
4712 names.
4713 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
4714 b4_parser_file_name and b4_spec_defines_file instead of
4715 @output_parser_name@ and @output_header_name@, which are now redundant.
4716 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4717 b4_parser_file_name, b4_spec_defines_file, and the new
4718 @basename(FILENAME@) instead of @output_parser_name@ and
4719 @output_header_name@, which inappropriately escaped the file names as
4720 C string literals.
4721 * src/files.c (all_but_ext): Remove static qualifier.
4722 (compute_output_file_names): Move `free (all_but_ext)' to...
4723 (output_file_names_free): ... here since all_but_ext is needed later.
4724 * src/files.h (all_but_ext): Extern.
4725 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4726 exactly what MUSCLE_INSERT_STRING used to do.
4727 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
4728 characters are escaped properly.
4729 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4730 all_but_ext.
4731 For pkgdatadir muscle, maintain previous functionality by using
4732 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4733 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4734 digraphs would never be expanded. Hopefully no one has M4-special
4735 characters in his Bison installation path.
4736 * src/scan-skel.l: Don't parse @output_header_name@ and
4737 @output_parser_name@ anymore since they're now redundant.
4738 In @output, use decode_at_digraphs.
4739 Parse a new @basename command that invokes last_component.
4740 (decode_at_digraphs): New.
4741 (BASE_QPUTS): Remove unused.
4742 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
4743 (Output file name): New tests.
4744

4746
4747 Warn about output files that are generated by the skeletons and that
4748 conflict with other output files.
4749 * data/glr.c: Don't generate the header file here when glr.cc does.
4750 * src/files.c (file_names, file_names_count): New static globals.
4751 (compute_output_file_names): Invoke output_file_name_check for files
4752 not generated by the skeletons and remove existing checks.
4753 (output_file_name_check): New function that warns about conflicting
4754 output file names.
4755 (output_file_names_free): Free file_names.
4756 * src/files.h (output_file_name_check): Declare.
4757 * src/scan-skel.l: Invoke output_file_name_check for files generated by
4758 the skeletons.
4759 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
4760 (Conflicting output files): New tests.
4761

4767
4768 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
4769 Rename to...
4770 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
4771 update all uses.
4772 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
4773 (yypush_parse): Rename yypvars argument to yyps and remove redundant
4774 local pv.
4775 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
4776 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
4777
4778 2006-12-07 Bob Rossi <bob@brasko.net>
4779 and Joel Denny <jdenny@ces.clemson.edu>
4780
4781 * data/push.c (yypvarsinit): Change return type from void* to struct
4782 yypvars*. No longer cast to void* on return.
4783 (struct yypvars): Remove yylen since it need not be remembered between
4784 yypushparse invocations.
4785 (yypushparse): Don't copy between yylen and pv->yylen.
4786
4787 2006-12-05 Bob Rossi <bob@brasko.net>
4788
4789 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.

4795 push or pure mode.
4796 (yypushparse): Add b4_declare_parser_variables.
4797 Init new local variables, and remove init code for removed
4798 yypvars variables.
4799 (yyparse): Delete.
4800 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
4801 and yyparse for other modes.
4802 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
4803 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
4804 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
4805 (AT_PURE_LEX_IF): True if pure or push parser.
4806

4810 %printer's as experimental. Don't mention Java yet. Discussed at
4811 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
4812 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
4813 (2.3a): Annotate this entry to say the old forms of these features were
4814 also experimental.
4815 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,
4816 Table of Symbols): Say they're experimental. Comment out any mention
4817 of Java (we'll want this back eventually).
4818
4819 2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
4820
4821 Support a file name argument to %defines. Deprecate `=' in
4822 %file-prefix, %name-prefix, and %output. Discussed at
4823 <http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
4824 * NEWS (2.3a+): Mention.
4825 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
4826 form of %defines, and remove `=' from entries for %file-prefix,
4827 %name-prefix, and %output.
4828 * src/parse-gram.y (prologue_declaration): Implement.
4829 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
4830 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from

4834 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
4835 occurrence of each of %file-prefix and %output. Add check for %defines
4836 with argument.
4837 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
4838 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
4839 Remove the `=' from %output.
4840
4841 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
4842
4843 Don't escape $ in test case titles since Autoconf 2.61 now does that
4844 correctly.
4845 * tests/actions.at (Default %printer and %destructor are not for error
4846 or $undefined): Here.
4847 (Default %printer and %destructor are not for $accept): Here.
4848 * tests/input.at (Invalid $n and @n): Here.
4849
4850 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
4851
4852 Rename <!> to <>. Discussed starting at
4853 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
4854 * NEWS (2.3a+): Update.
4855 * doc/bison.texinfo (Freeing Discarded Symbols, Table of Symbols):
4856 Update.
4857 * src/parse-gram.y (TYPE_TAG_NONE, generic_symlist_item): Implement.
4858 * src/scan-gram.l (INITIAL): Implement.
4859 * src/symlist.c (symbol_list_default_tagless_new): Update comment.
4860 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
4861 comment.
4862 * tests/actions.at (Default tagless %printer and %destructor,
4863 Default tagged and per-type %printer and %destructor,
4864 Default %printer and %destructor are not for error or $undefined,
4865 Default %printer and %destructor are not for $accept,
4866 Default %printer and %destructor for mid-rule values): Update.
4867 * tests/input.at (Default %printer and %destructor redeclared,
4868 Unused values with default %destructor): Update.
4869
4870 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
4871
4872 Don't let %prec take a nonterminal.
4873 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
4874 token.
4875 * tests/input.at (%prec takes a token): New test checking that %prec
4876 won't take a nonterminal.
4877
4878 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
4879
4880 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
4881 it was double-quoted.
4882 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
4883 grammar is maintained with Bison's highest standards.
4884 * src/getargs.c: Fix some typos in Doxygen comments.
4885
4886 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
4887
4888 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
4889 later. Reported by Paul Eggert in
4890 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
4891 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
4892 * src/scan-code.l (translate_action): Don't bother invoking
4893 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
4894 (code_scanner_free): Instead of invoking
4895 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
4896 which frees more.
4897 * src/scan-gram.l (gram_scanner_free): Likewise.
4898 * src/scan-skel.l (scan_skel): Likewise.
4899
4900 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
4901
4902 * src/files.c (tr): Change return type to void.
4903 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
4904 has been called previously for the same key.
4905 (muscle_find): Return storage instead of value so that
4906 --enable-gcc-warnings doesn't produce warnings that the return discards
4907 const. aver that the value and storage are the same since storage
4908 could potentially be NULL when value is not.
4909 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
4910 same as 0.
4911
4912 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4913
4914 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
4915 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
4916 us a slightly cleaner distribution, and also works.
4917 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
4918 gnulib changes.
4919
4920 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
4921 and Paul Eggert <eggert@cs.ucla.edu>
4922
4923 Don't let Bison leak memory except when it complains.
4924 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
4925 (spec_defines_file, dir_prefix): Now char *, not const char *,
4926 since they are freed.
4927 * src/files.c: Likewise.
4928 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
4929 Likewise.
4930 (tr): Now operates in-place. All uses changed.
4931 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
4932 values.
4933 (compute_file_name_parts, compute_output_file_names): Don't store
4934 read-only data in variables that will be freed.
4935 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
4936 src_extension, and header_extension.
4937 (output_file_names_free): New public function to free
4938 spec_verbose_file, spec_graph_file, spec_defines_file,
4939 parser_file_name, and dir_prefix.
4940 * src/getargs.c (getargs): Don't store read-only data in variables that
4941 will be freed.
4942 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
4943 (which previously existed but was unused), and quotearg_free.
4944 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
4945 * src/muscle_tab.c: Likewise.
4946 (muscle_entry): Make the value char const *,
4947 and add a new storage member that is char * and can be freed.
4948 (muscle_entry_free): New private function.
4949 (muscle_init): Use it instead of free.
4950 (muscle_insert, muscle_grow): Update and use new storage member.
4951 (muscle_code_grow): Free the string passed to muscle_grow
4952 since it's not needed anymore.
4953 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
4954 add a new `char *code' member.
4955 ("{...}"): Declare semantic type as code.
4956 * src/scan-code.h (translate_rule_action):
4957 (translate_symbol_action, translate_code, translate_action): Return
4958 `char const *' rather than `char *' since external code should not free
4959 these strings.
4960 * src/scan-code.l: Likewise.
4961 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
4962 which is "{...}" in the parser.
4963 * tests/Makefile.am (maintainer-check-valgrind): Set
4964 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
4965 Valgrind.
4966 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
4967 complain.
4968 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
4969 expecting a non-zero exit status sets --leak-check=summary and
4970 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
4971 this case, and we don't want to hear about it.
4972
4973 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4974
4975 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
4976 instead of from the template, to simplify configuration a bit.
4977 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
4978 and m4/wint_t.m4, as they are needed with the latest gnulib.
4979
4980 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
4981
4982 Disable unset/unused mid-rule value warnings by default, and recognize
4983 --warnings=midrule-values to enable them. Discussed starting at
4984 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
4985 * NEWS (2.3a+): Mention.
4986 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum
4987 warnings): Add entry for midrule-values subargument.
4988 * src/reader.c (symbol_should_be_used): Don't return true just because
4989 the value is a set/used mid-rule value unless
4990 --warnings=midrule-values was specified.
4991 * tests/input.at (Unused values, Unused values before symbol
4992 declarations): Run tests with and without --warnings=midrule-values.
4993
4994 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
4995 than LIST_FREE directly.
4996
4997 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
4998
4999 Finish implementing --warnings=error, which should not be implied by
5000 --warnings=all (or by its synonyms -W and --warnings without
5001 subarguments).
5002 * src/complain.c (set_warning_issued): New function to report that
5003 warnings are being treated as errors and to record an error if so.
5004 Invoke...
5005 (warn_at, warn): ... here.
5006 * src/getargs.c (warnings_args, warnings_types): Reorder so that
5007 "error - warnings are errors" does not appear above "all - all of the
5008 above".
5009 (getargs): For -W and --warnings without subarguments, don't let
5010 FLAGS_ARGMATCH set warnings_error in warnings_flag.
5011 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
5012
5013 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
5014
5015 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
5016 empty subargument list. For example: `bison --warnings= parser.y'.
5017
5018 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5019
5020 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
5021 the parser header file so that gcc doesn't warn.
5022
5023 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5024
5025 Split the default %destructor/%printer into two kinds: <*> and <!>.
5026 Discussed starting at
5027 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
5028 * NEWS (2.3a+): Mention.
5029 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
5030 previous change today related to mid-rules.
5031 (Table of Symbols): Remove %symbol-default and add <*> and <!>.
5032 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
5033 (TYPE_TAG_ANY): Add as <*>.
5034 (TYPE_TAG_NONE): Add as <!>.
5035 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
5036 for <*> and <!>.
5037 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
5038 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
5039 * src/symlist.c (symbol_list_default_new): Split into tagged and
5040 tagless versions.
5041 (symbol_list_destructor_set, symbol_list_printer_set): Split
5042 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
5043 SYMLIST_DEFAULT_TAGLESS.
5044 * src/symlist.h: Update symbol_list_default*_new prototypes.
5045 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
5046 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
5047 * src/symtab.c (default_destructor, default_destructor_location,
5048 default_printer, default_printer_location): Split each into tagged and
5049 tagless versions.
5050 (symbol_destructor_get, symbol_destructor_location_get,
5051 symbol_printer_get, symbol_printer_location_get): Implement tagged
5052 default and tagless default cases.
5053 (default_destructor_set, default_printer_set): Split each into tagged
5054 and tagless versions.
5055 * src/symtab.h: Update prototypes.
5056 * tests/actions.at (Default %printer and %destructor): Rename to...
5057 (Default tagless %printer and %destructor): ... this, and extend.
5058 (Per-type %printer and %destructor): Rename to...
5059 (Default tagged and per-type %printer and %destructor): ... this, and
5060 extend.
5061 (Default %printer and %destructor for user-defined end token): Extend.
5062 (Default %printer and %destructor are not for error or $undefined):
5063 Update.
5064 (Default %printer and %destructor are not for $accept): Update.
5065 (Default %printer and %destructor for mid-rule values): Extend.
5066 * tests/input.at (Default %printer and %destructor redeclared): Extend.
5067 (Unused values with default %destructor): Extend.
5068
5069 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5070
5071 Don't apply the default %destructor/%printer to an unreferenced midrule
5072 value. Mentioned at
5073 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
5074 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
5075 like $@n instead of just @n so that the default %destructor/%printer
5076 logic doesn't see them as user-defined symbols.
5077 (symbol_is_dummy): Check for both forms of the name.
5078 * src/reader.c (packgram): Remove the `$' from each midrule symbol
5079 name for which the midrule value is referenced in any action.
5080 * tests/actions.at (Default %printer and %destructor for mid-rule
5081 values): New test.
5082 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
5083 for change to dummy symbol names.
5084
5085 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
5086
5087 Warn about unset midrule $$ if the corresponding $n is used.
5088 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
5089 $n usage.
5090 (packgram): Before invoking grammar_rule_check on any rule, make sure
5091 all actions have already been scanned in order to set `used' flags.
5092 Otherwise, checking that a midrule's $$ is set will not always work
5093 properly because the midrule check must forward-reference the midrule's
5094 parent rule.
5095 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
5096 warning.
5097
5098 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
5099
5100 More improvements to the documentation of the prologue alternatives:
5101 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
5102 Bison manual.
5103 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
5104 some text to clarify the relative importance of the new directives and
5105 to show how these directives may be viewed as code labels.
5106
5107 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
5108
5109 Similar to the recently removed %before-header, add %code-top as the
5110 alternative to the pre-prologue. Mentioned at
5111 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
5112 Also, let the prologue alternatives appear in the grammar section.
5113 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
5114 (prologue_declaration): Move the existing prologue alternatives to...
5115 (grammar_declaration): ... here and add %code-top.
5116 * src/scan-gram.l (PERCENT_CODE_TOP): New token.
5117
5118 Clean up and extend documentation for the prologue alternatives.
5119 * NEWS (2.3a+): Describe prologue alternatives.
5120 * doc/bison.texinfo (Prologue): Move discussion of prologue
5121 alternatives to...
5122 (Prologue Alternatives): ... this new section, and extend it to discuss
5123 all 4 directives in detail.
5124 (Table of Symbols): Clean up discussion of prologue alternatives and
5125 add %code-top.
5126
5127 2006-10-16 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5128
5129 DJGPP specific issues.
5130

5137
5138 Replace %*-header with %provides, %requires, %code. See discussion at
5139 http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00002.html
5140
5141 * data/bison.m4 (b4_user_requires, b4_user_provides): New.
5142 (b4_user_start_header): Remove.
5143 * data/glr.c: Use new macros instead of b4_*start_header
5144 and b4_*end_header.
5145 * data/glr.cc: Likewise.
5146 * data/lalr1.cc: Likewise.
5147 * data/push.c: Likewise.
5148 * data/yacc.c: Likewise.
5149
5150 * doc/bison.texinfo: Remove %before-header, rename
5151 %{start,end,after}-header to %requires, %provides, %code.
5152
5153 * src/parse-gram.y: Likewise (also rename token names accordingly).
5154 * src/scan-gram.l: Likewise.
5155 * tests/actions.at: Likewise.
5156
5157 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
5158
5159 * lib/Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS).
5160 Problem reported by Joel E. Denny.
5161
5162 2006-10-14 Jim Meyering <jim@meyering.net>
5163
5164 (Sync from coreutils.)
5165 Work also when the working directory (with e.g. coreutils sources)
5166 is version controlled with git, rather than CVS.
5167 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
5168 rather than CVS.
5169 In messages and comments, say e.g., "checked-out sources",
5170 rather than "CVS sources".
5171 (version_controlled_file): New function. Work for git as well as
5172 for CVS. Don't use grep's -q option.
5173 (slurp): Call it here, in place of CVS-specific code.
5174
5175 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
5176
5177 Fix testsuite for ./configure --enable-gcc-warnings:
5178 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
5179 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
5180 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
5181 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
5182 * test/regression.at (Diagnostic that expects two alternatives):
5183 Likewise.
5184
5185 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5186
5187 * bootstrap.conf (gnulib_modules): Add config-h.
5188 * djgpp/subpipe.c: Include <config.h> unconditionally; don't
5189 worry about HAVE_CONFIG_H.
5190 * lib/abitset.c: Likewise.
5191 * lib/bitset.c: Likewise.
5192 * lib/bitset_stats.c: Likewise.
5193 * lib/bitsetv-print.c: Likewise.

5198 * lib/subpipe.c: Likewise.
5199 * lib/timevar.c: Likewise.
5200 * lib/vbitset.c: Likewise.
5201 * lib/bitset.c: Include "bitset.h" first, to test interface.
5202 * lib/bitset_stats.c: Include "bitset_stats.h" first.
5203 * lib/bitsetv-print.c: Include "bitsetv-print.h" first.
5204 * lib/bitsetv.c: Include "bitsetv.h" first.
5205 * lib/get-errno.c: Include "get-errno.h" first.
5206 * m4/.cvsignore: Add config-h.m4.
5207 * tests/actions.at (Default %printer and %destructor for ...):
5208 Adjust expected line numbers in output to reflect removal of #if
5209 HAVE_CONFIG_H lines.
5210 * tests/glr-regression.at (Missed %merge type warnings when ...):
5211 Likewise.
5212 * tests/regression.at (Braced code in declaration in rules section):
5213 Likewise.
5214 * tests/atlocal.in (CPPFLAGS): Don't define HAVE_CONFIG_H.
5215 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
5216 Include <config.h> unconditionally.
5217
5218 * bootstrap: Sync from coreutils, as follows:
5219
5220 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
5221
5222 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
5223 variable was sometimes used without being initialized. This
5224 messed up the installation of the INSTALL file in some cases.
5225
5226 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5227
5228 * bootstrap (usage, main program, symlink_to_gnulib): Add option
5229 --copy. Inspired by a suggestion from Bruno Haible.
5230
5231 2006-10-03 Jim Meyering <jim@meyering.net>
5232
5233 * bootstrap: Undo last change to this file, since now gnulib-tool
5234 sticks with the automake default in generating dependencies.
5235
5236 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5237
5238 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
5239 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
5240
5241 * doc/bison.1: Add copyright notice.
5242
5243 * data/glr.c: Don't include <stdarg.h>; not used.
5244
5245 * NEWS: The -g and --graph options now output graphs in Graphviz
5246 DOT format, not VCG format.
5247 * doc/bison.1: Likewise.
5248 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
5249 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
5250 of this change in
5251 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
5252 * TODO: Remove Graphviz entry.
5253 * src/Makefile.am (bison_SOURCES): Add graphviz.c and graphviz.h;
5254 remove vcg.c, vcg.h, vcg_defaults.h.

5260 * src/print_graph.h: Likewise.
5261 * src/getargs.c (usage): Make usage description more generic.
5262 * src/print_graph.c: Include graphviz.h rather than vcg.h.
5263 (static_graph, fgraph): Remove. All uses changed to pass
5264 arguments instead of sharing a static var.
5265 (print_core, print_actions, print_state, print_graph):
5266 Output graphviz format rather than VCG format.
5267 * tests/.cvsignore: Remove *.vcg; add *.dot.
5268 * tests/output.at: Expect *.dot files, not *.vcg files.
5269
5270 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
5271 accommodates the 2006-10-08 change.
5272
5273 2006-10-11 Bob Rossi <bob@brasko.net>
5274
5275 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.

5277 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
5278 (yypvarsinit): Remove init of removed fields.
5279 (yypushparse): Remove use of removed fields; use new macros instead.
5280
5281 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
5282
5283 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
5284 in a push parser. Reindent slightly to match yacc.c better.
5285
5286 2006-10-11 Bob Rossi <bob@brasko.net>
5287
5288 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
5289 yymsg_alloc fields.
5290 (yypvarsinit, yypushparse): Remove init of removed fields.
5291 (yypushparse): Use yymsgbuf instead of yymsgbuf_ptr.
5292
5293 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5294
5295 * THANKS: Add Paolo Bonzini and Bob Rossi.
5296
5297 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
5298
5299 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
5300 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
5301 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
5302 b4_define_user_cde and uses): Remove.
5303 (b4_comment, b4_prefix, b4_sync_start): New.
5304 * data/bison.m4: New file, with most of the content removed from c.m4.
5305 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
5306 * src/output.c (output_skeleton): Pass bison.m4.
5307 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
5308 only if specified.
5309
5310 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
5311
5312 Fix test failure reported by Tom Lane in
5313 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
5314 and try to make such failures easier to catch in the future.
5315 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
5316 that's now the caller's responsibility.
5317 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
5318 Set yychar = YYEOF if it's negative.
5319 * tests/actions.at (yylex): Abort if asked to read past EOF.
5320 * tests/conflicts.at (yylex): Likewise.
5321 * tests/cxx-type.at (yylex): Likewise.
5322 * tests/glr-regression.at (yylex): Likewise.
5323 * tests/input.at (yylex): Likewise.
5324 * tests/regression.at (yylex): Likewise.
5325 * tests/torture.at (yylex): Likewise.
5326
5327 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
5328
5329 Fix problems with translating English-language diagnostics.
5330 * bootstrap: Fix bug introduced in recent bootstrap changes, with
5331 respect to bison-runtime pot generation. The YY_ stuff
5332 wasn't being captured.
5333 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
5334 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
5335 * runtime-po/POTFILES.in: Add data/push.c.
5336
5337 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
5338
5339 Merge bootstrap changes from coreutils.
5340
5341 2006-09-28 Jim Meyering <jim@meyering.net>
5342
5343 Automatically generated dependencies are important even
5344 when all of the sources in a directory come from gnulib.
5345 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
5346 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
5347
5348 2006-09-23 Jim Meyering <jim@meyering.net>
5349
5350 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
5351
5352 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5353
5354 * bootstrap: Add support for --force.
5355 (usage): New function. Describe usage less tersely.
5356 (CVS_only_file): New var.
5357
5358 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
5359
5360 * data/push.c (YYPUSH_MORE): Make it an enum instead.
5361 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
5362 Adjust white space and comments to match GNU style better.
5363
5364 2006-09-20 Bob Rossi <bob@brasko.net>
5365
5366 * data/push.c (yyresult_get): Remove function.
5367 (YYPUSH_MORE): Add #define.
5368 (yypushparse): Modify return value.
5369
5370 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5371
5372 * stamp-h.in: Remove; no longer needed.
5373 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
5374 Remove config.h, config.hin, intl (no longer created).
5375 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
5376 stamp-h1.
5377
5378 Sync bootstrap from coreutils, as follows:
5379
5380 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
5381
5382 * bootstrap (symlink_to_gnulib): New function.
5383 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
5384 to copies-of-gnulib.
5385 (cp_mark_as_generated, slurp, gnulib_files):
5386 Avoid making a copy if it's the same as the old version.
5387 (gnulib_files): Add support for this variable (used by Bison).
5388
5389 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5390
5391 * src/getargs.c (usage): Rework to use conventions similar to
5392 coreutils, to make translation a bit easier and the code a bit
5393 smaller. Problem reported by Tim Van Holder.
5394
5395 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
5396
5397 Use some of gnulib's new modules, taken from coreutils.
5398
5399 * bootstrap: Sync from coreutils, except add support for gnulib_files.
5400 * bootstrap.conf: New file.
5401 (gnulib_modules): Add configmake, inttypes, unistd.
5402 (XGETTEXT_OPTIONS): Add complain, complain_at,
5403 fatal, fatal_at, warn, warn_at, unexpected_end.
5404 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
5405 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
5406 (gl_EARLY): Add.
5407 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
5408 (gl_INIT): Add
5409 (GNULIB_AUTOCONF_SNIPPET): Remove.
5410 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
5411 the pickiest.
5412 * lib/.cvsignore: Add inttypes_.h.
5413 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
5414 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
5415 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
5416 no-longer-necessary initializations.
5417 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
5418 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
5419 use the unistd module.
5420 * src/system.h: Likewise.
5421 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5422 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5423 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5424 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5425 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5426 * src/system.h: Include inttypes.h unconditionally, now that we
5427 use the inttypes module. Don't bother to include stdint.h, since
5428 inttypes.h now does that for us.
5429 (LOCALEDIR): Remove, now that we use the configmake module.
5430 * src/getargs.c: Include configmake.h.
5431 * src/main.c: Likewise.
5432 * src/output.c: Likewise.
5433 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5434 not from $abs_top_builddir, since config.h moved.
5435
5436
5437 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5438 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5439
5440 * src/parse-gram.y (symbol_declaration): Don't put statements
5441 before declarations; it's not portable to C89.
5442 * src/scan-code.l (handle_action_at): Likewise.
5443
5444 * src/scan-code.l: Always initialize braces_level; the old code
5445 left it uninitialized and therefore had undefined behavior.
5446
5447 Don't attempt to redefine 'assert', since it runs afoul of
5448 systems where standard headers (mistakenly) include <assert.h>.
5449 Instead, define and use our own alternative, called 'aver'.
5450 * src/reader.c: Don't include assert.h, since we no longer
5451 use assert.
5452 * src/scan-code.l: Likewise.
5453 * src/system.h (assert): Remove, replacing with....
5454 (aver): New function, taking a bool arg. All uses changed.
5455 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5456 not merely an integer.
5457
5458 2006-09-15 Bob Rossi <bob@brasko.net>
5459
5460 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5461 * data/c.m4 (YYPUSH): New.
5462 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
5463 * src/getargs.c (push_parser): New var.
5464 * src/getargs.h (push_parser): New declaration.
5465 * src/output.c (prepare): Add macro insertion of `push_flag'.
5466 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5467 (prologue_declaration): Parse %push-parser.
5468 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5469 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
5470 list of removed lines from the traces observed.
5471 (AT_CHECK_CALC_LALR): Added push parser tests.
5472
5473 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
5474
5475 * NEWS: Version 2.3a.
5476 * configure.ac (AC_INIT): Likewise.
5477
5478 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
5479 "#define YYSTYPE int" that caused "make maintainer-check" to fail
5480 due to header ordering dependencies. I don't know why the #define
5481 was there.
5482
5483 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
5484 runtime cost when YYDEBUG is not defined, and so that some tests
5485 that used to fail now work. Problem and initial suggestion by
5486 Paolo Bonzini.
5487 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
5488 * data/glr.cc (b4_parser_class_name):
5489 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
5490 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
5491 (yydebug_) [YYDEBUG]: New member.
5492 (yycdebug_): Now defined only if YYDEBUG.
5493 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
5494 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
5495 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
5496 if YYYDEBUG.
5497 (debug_stream, set_debug_stream, debug_level, set_debug_level):
5498 Define only if YYDEBUG.
5499 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
5500 set_debug_level.
5501 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
5502 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
5503 AT_CHECK_CALC_GLR_CC that are working now.
5504
5505 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5506
5507 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
5508 We don't need them in glr.cc, and glr.c defines them.
5509 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
5510 assumes that defining it to anything is the same as defining
5511 it to 1. Problem reported by Paolo Bonzini.
5512
5513 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
5514
5515 * data/c.m4 (b4_null, b4_case): Define.
5516 * src/output.c (prepare_symbols): Use b4_null.
5517 (user_actions_output): Use b4_case.
5518
5519 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
5520
5521 * data/glr.c (b4_shared_declarations): Put start-header first,
5522 before any #includes that we generate, so that feature-test
5523 macros work. Problem reported by Michael Deutschmann in
5524 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
5525 * data/lalr1.cc: Likewise.
5526 * doc/bison.texinfo (Prologue): Document that feature-test macros
5527 should be defined before any Bison declarations.
5528 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
5529 that depend on location.hh after, not before, Bison decls, since
5530 we now include location.hh after the first user prologue.
5531
5532 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
5533 Sander Brandenburg in
5534 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
5535 Also, fix minor white space and comment issues.
5536 (Prologue): Mention that it's better to define feature-test macros
5537 before Bison declarations. Problem reported by Michael Deutschmann.
5538
5539 * README-cvs: Fix typo: "&" should be "&&". Problem reported
5540 by Jim Meyering.
5541 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
5542 This adjusts to recent gnulib changes.
5543
5544 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5545
5546 Finish implementation of per-type %destructor/%printer. Discussed
5547 starting at
5548 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
5549 and
5550 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
5551 * NEWS (2.3+): Add a description of this feature to the default
5552 %destructor/%printer description.
5553 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
5554 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5555 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
5556 list node contains a semantic type.
5557 * src/symtab.c, src/symtab.h: Extend with a table that associates
5558 semantic types with their %destructor's and %printer's.
5559 (semantic_type_from_uniqstr, semantic_type_get,
5560 semantic_type_destructor_set, semantic_type_printer_set): New functions
5561 composing the public interface of that table.
5562 (symbol_destructor_get, symbol_destructor_location_get,
5563 symbol_printer_get, symbol_printer_location_get): If there's no
5564 per-symbol %destructor/%printer, look up the per-type before trying
5565 the default.
5566 * tests/actions.at (Per-type %printer and %destructor): New test case.
5567 * tests/input.at (Default %printer and %destructor redeclared):
5568 Extend to check that multiple occurrences of %symbol-default in a
5569 single %destructor/%printer declaration is an error.
5570 (Per-type %printer and %destructor redeclared, Unused values with
5571 per-type %destructor): New test cases.
5572
5573 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5574
5575 Require default %destructor/%printer to be declared using
5576 %symbol-default instead of an empty symbol list, and start working on
5577 new per-type %destructor/%printer. Discussed at
5578 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
5579 * NEWS (2.3+): Add %symbol-default to example.
5580 * bison.texinfo (Freeing Discarded Symbols): Likewise.
5581 (Table of Symbols): Add entry for %symbol-default.
5582 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
5583 (generic_symlist, generic_symlist_item): New nonterminals for creating
5584 a list in which each item is a symbol, semantic type, or
5585 %symbol-default.
5586 (grammar_declaration): Use generic_symlist in %destructor and %printer
5587 declarations instead of symbols.1 or an empty list.
5588 (symbol_declaration, precedence_declaration, symbols.1): Update actions
5589 for changes to symbol_list.
5590 * src/reader.c: Update for changes to symbol_list.
5591 * src/scan-code.l: Likewise.
5592 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
5593 * src/symlist.c, src/symlist.h: Extend such that a list node may
5594 represent a semantic type or a %symbol-default in addition to just an
5595 ordinary symbol. Add switched functions for setting %destructor's and
5596 %printer's.
5597 * tests/actions.at, tests/input.at: Add %symbol-default to all default
5598 %destructor/%printer declarations.
5599
5600 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
5601
5602 Whether the default %destructor/%printer applies to a particular symbol
5603 isn't a question of whether the user *declares* that symbol (in %token,
5604 for example). It's a question of whether the user by any means
5605 *defines* the symbol at all (by simply using a char token, for
5606 example). $end is defined by Bison whereas any other token with token
5607 number 0 is defined by the user. The error token is always defined by
5608 Bison regardless of whether the user declares it with %token, but we
5609 may one day let the user define error as a nonterminal instead.
5610 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
5611 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
5612 the meaning of "user-defined".
5613 * tests/actions.at (Default %printer and %destructor for user-declared
5614 end token): Rename to...
5615 (Default %printer and %destructor for user-defined end token): ...
5616 this.
5617
5618 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
5619 computation of whether to apply the default, don't maintain a list of
5620 every Bison-defined symbol. Instead, just check for a first character
5621 of '$', which a user symbol cannot have, and check for the error token.
5622
5623 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
5624
5625 Don't apply the default %destructor or %printer to the error token,
5626 $undefined, or $accept. This change fits the general rule that the
5627 default %destructor and %printer are only for user-declared symbols,
5628 and it solves several difficulties that are described in the new test
5629 cases listed below.
5630 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
5631 * tests/actions.at (Default %printer and %destructor are not for error
5632 or $undefined, Default %printer and %destructor are not for $accept):
5633 New test cases.
5634
5635 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
5636
5637 Allow %start after the first rule.
5638 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
5639 when parsing the first rule.
5640 (check_and_convert_grammar): Search for it here after all grammar
5641 declarations have been parsed. Skip midrules, which have dummy LHS
5642 nonterminals.
5643 * src/symtab.c (symbol_is_dummy): New function.
5644 * src/symtab.h (symbol_is_dummy): Declare it.
5645 * tests/input.at (%start after first rule): New test.
5646
5647 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5648
5649 Redo some of the previous commit: add back the ability to use
5650 non-aliased/undeclared string literals since it might be useful to
5651 those declaring %token-table.
5652 * src/reader.c (check_and_convert_grammar): Undo changes in previous
5653 commit: don't worry about complaints from symbols_pack.
5654 * src/symtab.c (symbol_new, symbol_class_set,
5655 symbol_check_alias_consistency): Undo changes in previous commit: count
5656 each string literal as a new symbol and token, assign it a symbol
5657 number, and don't complain about non-aliased string literals.
5658 (symbols_pack): Since symbol_make_alias still does not decrement symbol
5659 and token counts but does still set aliased tokens to the same number,
5660 symbol_pack_processor now leaves empty slots in the symbols array.
5661 Remove those slots.
5662 * tests/regression.at (Undeclared string literal): Remove test case
5663 added in previous commit since non-aliased string literals are allowed
5664 again.
5665 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
5666 remove unnecessary string literal declarations.
5667 * tests/sets.at (Firsts): Likewise.
5668
5669 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5670
5671 Don't allow an undeclared string literal, but allow a string literal to
5672 be used before its declaration.
5673 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
5674 symbols_pack complained.
5675 * src/symtab.c (symbol_new): Don't count a string literal as a new
5676 symbol.
5677 (symbol_class_set): Don't count a string literal as a new token, and
5678 don't assign it a symbol number since symbol_make_alias does that.
5679 (symbol_make_alias): It's not necessary to decrement the symbol and
5680 token counts anymore. Don't assume that an alias declaration occurs
5681 before any uses of the identifier or string, and thus don't assert that
5682 one of them has the highest symbol number so far.
5683 (symbol_check_alias_consistency): Complain if there's a string literal
5684 that wasn't declared as an alias.
5685 (symbols_pack): Bail if symbol_check_alias_consistency failed since
5686 symbol_pack asserts that every token has been assigned a symbol number
5687 although undeclared string literals have not.
5688 * tests/regression.at (String alias declared after use, Undeclared
5689 string literal): New test cases.
5690 (Characters Escapes, Web2c Actions): Declare string literals as
5691 aliases.
5692 * tests/sets.at (Firsts): Likewise.
5693
5694 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
5695
5696 In the grammar scanner, STRING_FINISH unclosed constructs and return
5697 them to the parser in order to improve error messages.
5698 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
5699 SC_BRACED_CODE, SC_PROLOGUE): Implement.
5700 * tests/input.at (Unclosed constructs): New test case.
5701 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
5702 seen.
5703
5704 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
5705 unused global.
5706
5707 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
5708
5709 Handle string aliases for character tokens correctly.
5710 * src/symtab.c (symbol_user_token_number_set): If the token has an
5711 alias, check and set its alias's user token number instead of its own,
5712 which is set to indicate the alias. Previously, every occurrence of
5713 the character token in the grammar overwrote that alias indicator with
5714 the character code.
5715 * tests/input.at (String aliases for character tokens): New test.
5716
5717 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
5718
5719 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
5720
5721 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
5722
5723 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
5724 to prevent failures when building on older platforms.
5725 Check for autopoint failure.
5726 Set XGETTEXT_OPTIONS to values that check for C format strings,
5727 so that translators are warned about them (this also helps
5728 prevent core dumps).
5729
5730 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
5731 function, since it simplifies our code a bit.
5732
5733 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
5734 rather than -W, so we don't get bogus warnings about sign comparisons.
5735 Add -Wpointer-arith, since that warning is useful (it reports code
5736 that does not conform to C89 and that some compilers reject).
5737 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
5738 since it's no longer needed.
5739
5740 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
5741
5742 Clean up scanners a bit.
5743 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
5744 definitions so gcc won't warn when obstack_for_string is unused.
5745 * src/scan-code.l: config.h and system.h are already #include'd by
5746 scan-code-c.c, so get rid of them here.
5747 * src/scan-gram.l: Likewise.
5748 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
5749 definitions rather than duplicating the rest of it.
5750 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
5751
5752 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
5753
5754 Suppress signed/unsigned comparison warnings for yycheck.
5755 * data/c.m4 (b4_safest_int_type): New macro.
5756 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
5757 a signed int type, cast it to b4_safest_int_type first.
5758 * data/yacc.c: Likewise.
5759 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
5760 also overwritten.
5761
5762 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
5763
5764 * doc/bison.texinfo: Fix some typos.
5765
5766 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
5767
5768 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
5769 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
5770
5771 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
5772 the latest gnulib does this a different way.
5773 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
5774 translation was patched, so stop omitting it.
5775
5776 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5777
5778 Enable declaration of default %printer/%destructor. Make the parser
5779 use these for all user-declared grammar symbols for which the user does
5780 not declare a specific %printer/%destructor. Thus, the parser uses it
5781 for token 0 if the user declares it but not if Bison generates it as
5782 $end. Discussed starting at
5783 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
5784 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
5785 and
5786 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
5787 * NEWS (2.3+): Mention.
5788 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
5789 declare a %destructor for a mid-rule's semantic value. It's just
5790 impossible to declare one specific to it.
5791 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
5792 code. Describe default %destructor form.
5793 * src/parse-gram.y (grammar_declaration): Parse default
5794 %printer/%destructor declarations.
5795 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
5796 and symbol_destructor_location_get rather than accessing the destructor
5797 and destructor_location members of struct symbol.
5798 (symbol_printers_output): Likewise but for %printer's.
5799 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
5800 again.
5801 * src/symtab.c (default_destructor, default_destructor_location,
5802 default_printer, default_printer_location): New static global
5803 variables to record the default %destructor and %printer.
5804 (symbol_destructor_get, symbol_destructor_location_get,
5805 symbol_printer_get, symbol_printer_location_get): New functions to
5806 compute the appropriate %destructor and %printer for a symbol.
5807 (default_destructor_set, default_printer_set): New functions to set the
5808 default %destructor and %printer.
5809 * src/symtab.h: Prototype all those new functions.
5810 * tests/actions.at (Default %printer and %destructor): New test to
5811 check that the right %printer and %destructor are called, that they're
5812 not called for $end, and that $$ and @$ work correctly.
5813 (Default %printer and %destructor for user-declared end token): New
5814 test to check that the default %printer and %destructor are called for
5815 a user-declared end token.
5816 * tests/input.at (Default %printer and %destructor redeclared, Unused
5817 values with default %destructor): New tests to check related grammar
5818 warnings and errors.
5819
5820 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5821
5822 Clean up handling of %destructor for the end token (token 0).
5823 Discussed starting at
5824 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
5825 and
5826 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
5827
5828 Make the skeletons consistent in how they pop the end token and invoke
5829 its %destructor.
5830 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
5831 state, which has token number 0, since this would invoke the
5832 %destructor for the end token.
5833 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
5834 until after shifting the end token, or else it won't be popped.
5835 * data/yacc.c (yyparse): Likewise.
5836
5837 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
5838 it's the end token. Upon termination, destroy an unshifted lookahead
5839 even when it's the end token.
5840 * data/lalr1.cc (yy::parser::parse): Likewise.
5841 * data/yacc.c (yyparse): Likewise.
5842
5843 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
5844 value warnings for the end token when the user gives the end token a
5845 %destructor.
5846
5847 * tests/actions.at (Printers and Destructors): Test all the above.
5848
5849 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5850
5851 Update to latest gnulib and gettext versions.
5852 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
5853 Add fopen-safer.
5854 (gnulib_files): Add m4/warning.m4. Don't worry about files
5855 overwritten by autopoint.
5856 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
5857 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
5858 rejects them.
5859 Don't use autoreconf; instead, invoke autopoint etc. by hand,
5860 so that we can remove the intl files at a better time.
5861 (intl_files_to_remove): Remove aclocal.m4, since it gets
5862 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
5863 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
5864 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
5865 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
5866 Remove datarootdir hack; no longer needed.
5867 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
5868 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
5869 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
5870 strdup.h.
5871 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
5872 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
5873
5874 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5875
5876 * bootstrap: Adjust to today's change to gnulib-tool by invoking
5877 it with --assume-autoconf='latest-stable'.
5878
5879 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
5880
5881 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
5882 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
5883 YYSTYPE' and `{'.
5884 * src/muscle_tab.h (muscle_grow): Replace the header comments with
5885 those from muscle_tab.c since the old ones are misleading.
5886
5887 2006-07-13 Akim Demaille <akim@epita.fr>
5888
5889 Support %define "KEY" {VALUE}.
5890 * src/scan-code.h, src/scan-code.l (translate_action)
5891 (translate_rule_action, translate_symbol_action, translate_code):
5892 Return char *, not const char *.
5893 * src/parse-gram.y (declaration): Rename as...
5894 (prologue_declaration): this.
5895 (string_content): Remove this nonterminal, use STRING.
5896 (braceless, content, content.opt): New nonterminal.
5897 Use them.
5898 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
5899 as value.
5900 * src/scan-gram.l (getargs.h): Don't include it.
5901
5902 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
5903
5904 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
5905 rather than a for-loop that declares a local bool variable. This
5906 should work around a compatibility problem with a Cray x1e C++
5907 compiler reported by Hung Nguyen in
5908 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
5909 The for-loop was introduced in the 2004-11-17 change but I don't
5910 know why it was needed.
5911
5912 2006-07-12 Akim Demaille <akim@epita.fr>
5913
5914 * data/c.m4: Comment changes.
5915
5916 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
5917
5918 * src/complain.c (error_message, ERROR_MESSAGE): New.
5919 To factor...
5920 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
5921 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
5922
5923 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5924
5925 * NEWS: Instead of %union, you can define and use your own union type
5926 YYSTYPE if your grammar contains at least one <type> tag.
5927 Your YYSTYPE need not be a macro; it can be a typedef.
5928 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
5929 (Union Decl, Decl Summary): Document this.
5930 * data/glr.c (YYSTYPE): Implement this.
5931 * data/glr.cc (YYSTYPE): Likewise.
5932 * data/lalr1.cc (YYSTYPE): Likewise.
5933 * data/yacc.c (YYSTYPE): Likewise.
5934 * src/output.c (prepare): Output tag_seen_flag.
5935 * src/parse-gram.y (declaration, grammar_declaration):
5936 Use 'union_seen' rather than 'typed' to determine whether
5937 %union has been seen, since grammars can now be typed without
5938 %union.
5939 (symbol_declaration, type.opt, symbol_def):
5940 Keep track of whether a tag has been seen.
5941 * src/reader.c (union_seen, tag_seen): New vars.
5942 (typed): remove.
5943 * src/reader.h (union_seen, tag_seen, typed): Likewise.
5944 * src/scan-code.l (untyped_var_seen): New variable.
5945 (handle_action_dollar): Adjust to above changes.
5946 (handle_action_dollar, handle_action_at):
5947 Improve overflow checking for outlandish numbers.
5948 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
5949 avoid new diagnostics generated by above changes.
5950 * tests/regression.at (YYSTYPE typedef): Add test to check
5951 for type tags without %union.
5952
5953 * src/symlist.c (symbol_list_length): Return int, not unsigned
5954 int, since callers expect int. This may need to get revisited
5955 once we have proper integer overflow checking.
5956
5957 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
5958 object is now static.
5959
5960 * src/getargs.c (flags_argmatch): Return void, not int,
5961 to pacify ./configure --enable-gcc-warnings.
5962
5963 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
5964 since last_string is already defined to FLEX_PREFIX (last_string).
5965
5966 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5967
5968 Implement --warnings/-W.
5969 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
5970 replaced by...
5971 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
5972 Adjust callers.
5973 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
5974 (warnings_args, warnings_types): New.
5975 (getargs, short_options, long_options): Accept -W/--warnings.
5976 Sort the options by alphabetical order, upper case letter right
5977 before its lower case.
5978
5979 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5980
5981 Change %merge result type clash warnings to errors. Discussed at
5982 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
5983 * src/reader.c (record_merge_function_type): Use complain_at.
5984 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5985 declared later): Update test case results.
5986
5987 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5988
5989 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
5990 to be in alphabetical order.
5991 (trace_args): Spelling fixes.
5992
5993 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5994
5995 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
5996 so they don't collide with user-defined macros.
5997 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
5998 this was never guaranteed, and now that we're using gnulib stdint,
5999 which defines int_fast16_t to long int, the problem is exposed.
6000
6001 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
6002
6003 * data/c.m4 (b4_basename): Simplify a bit, since we don't
6004 need the full POSIX semantics (and weren't implementing them
6005 anyway).
6006
6007 Adjust to Autoconf 2.60 and today's gnulib.
6008 * bootstrap (gnulib_modules): Add stdint.
6009 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
6010 no longer copies it.
6011 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6012 since stdint needs the former and wcwidth (which is now required
6013 by mbswidth) needs the latter.
6014 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6015 work around a compatibility glitch between gettext 0.14.6 and
6016 Autoconf 2.60.
6017 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
6018 Do not check for uintptr_t, since new stdint module does the right
6019 thing.
6020 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
6021 Add stdint.h, stdint_.h, wcwidth.h.
6022 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
6023 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
6024 stdint.m4, wchar_t.m4, wcwidth.m4.
6025 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
6026 usual order for ../lib/*.h files.
6027 (file_name_split): Use last_component, not base_name, to adjust
6028 to gnulib changes.
6029 * src/parse-gram.h: Include <strverscmp.h> in the usual order
6030 for ../lib/*.h files.
6031 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
6032 Define unconditionally, since we now assume the stdint module.
6033 * src/scan-skel.l: Include <dirname.h>.
6034 (BASE_QPUTS): Use last_component, not base_name.
6035 * src/system.h: Include <unlocked-io.h> in the usual order
6036 for ../lib/*.h files. Include <stdint.h> unconditionally,
6037 since we now use the stdint module.
6038 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
6039 HAVE_UINTPTR_T, since we now use the stdint module.
6040 (base_name): Remove decl, since files now include <dirname.h>
6041 to get the decl.
6042
6043 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6044
6045 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
6046 New, default to 1.
6047 * data/yacc.c, data/glr.c, data/location.cc: Use them.
6048 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
6049 default.
6050 * tests/calc.at: Adjust.
6051
6052 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6053
6054 * data/c.m4 (b4_basename): New.
6055 (b4_syncline): Also output the location of its invocation (from
6056 the skeleton).
6057 (b4_user_action, b4_define_user_action, b4_user_actions)
6058 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
6059 (b4_user_stype): New.
6060 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
6061
6062 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6063
6064 In the grammar file, the first column is 1 not 0 on the first line as
6065 on every other line.
6066 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
6067 * tests/input.at (Torturing the Scanner): Update output.
6068
6069 * src/scan-gram.l (scanner_cursor): Declare it static.
6070
6071 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6072
6073 In warnings, say "previous declaration" rather than "first
6074 declaration".
6075 * src/symtab.c (redeclaration): Do that here.
6076 * src/reader.c (record_merge_function_type): In the case of a result
6077 type clash, report the previous declaration rather than the very first
6078 one in the grammar file.
6079 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6080 declared later): Add a third declaration to check this behavior.
6081 * tests/input.at (Incompatible Aliases): Update output.
6082
6083 2006-06-27 Akim Demaille <akim@epita.fr>
6084
6085 * doc/Doxyfile.in: New.
6086 * doc/Makefile.am: Use it.
6087 * src/lalr.h, src/symtab.h: Initial doxygenation.
6088
6089 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6090
6091 Don't miss %merge result type warnings just because the LHS types are
6092 declared after the %merge. This continues the effort of the previous
6093 patch.
6094 * src/reader.c (get_merge_function): Don't set the merger type yet.
6095 (record_merge_function_type): New function for setting the merger type
6096 and checking for clashes.
6097 (grammar_current_rule_merge_set): Set the location of the %merge for
6098 the current rule.
6099 (packgram): Invoke record_merge_function_type for each rule now that
6100 all symbol type declarations have been parsed.
6101 * src/reader.h (merger_list.type_declaration_location): New member
6102 storing the location of the first %merge from which the type for this
6103 merging function was derived.
6104 * src/symlist.h (symbol_list.merger_declaration_location): New member
6105 storing the location of a rule's %merge, if any.
6106 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6107 declared later): New test to catch the error fixed by the above patch.
6108
6109 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6110
6111 Get action warnings (grammar_rule_check) right even when symbol
6112 declarations appear after the rules. Discussed at
6113 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
6114 and
6115 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
6116 Don't mistake the type of $$ in a midrule to be that of its parent
6117 rule's $$.
6118 * src/reader.c (grammar_current_rule_end): Don't invoke
6119 grammar_rule_check yet since not all symbol declarations may have been
6120 parsed yet.
6121 (grammar_midrule_action): Likewise.
6122 Don't record whether the midrule's $$ has been used yet since actions
6123 haven't been translated yet.
6124 Record the midrule's parent rule and its RHS index within the parent
6125 rule.
6126 (grammar_current_rule_action_append): Don't translate the action yet
6127 since not all symbol declarations may have been parsed yet and, thus,
6128 warnings about types for $$, $n, @$, and @n can't be reported yet.
6129 (packgram): Translate the action and invoke grammar_rule_check now that
6130 all symbol declarations have been parsed.
6131 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6132 after parsing the entire grammar file, the symbol list here in the case
6133 of a midrule is actually the midrule's empty RHS, so reference its
6134 parent rule's RHS where necessary.
6135 On the other hand, now that you can already know it's a midrule, you
6136 aren't forced to think $$ has the same type as its parent rule's $$.
6137 (handle_action_at): In the case of a midrule, reference the parent rule
6138 where necessary.
6139 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6140 members.
6141 (symbol_list_length): Now that this is invoked after all rules have
6142 been parsed, a NULL symbol (rather than a NULL symbol list node)
6143 terminates a rule. symbol_list_print already does this correctly.
6144 * src/symlist.h (symbol_list.midrule_parent_rule,
6145 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6146 remember their relationships with their parents.
6147 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6148 fixed by the above patch.
6149 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6150 implementing...
6151 (Unused values): ... this old test case and...
6152 (Unused values before symbol declarations): ... this new test case.
6153 This one is the same as `Unused values' except that all symbol
6154 declarations appear after the rules in order to catch the rest of the
6155 errors fixed by the above patch.
6156
6157 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6158
6159 More cleanup.
6160 * src/reader.c (current_rule): Declare it static since it's no longer
6161 used outside this file.
6162 (grammar_current_rule_action_append): Remove redundant arguments from
6163 translate_rule_action invocation.
6164 * src/reader.h (current_rule): Remove this unused extern.
6165 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
6166 * src/scan-code.l (translate_rule_action): Likewise.
6167
6168 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
6169
6170 Clean up yesterday's patch.
6171 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
6172 to...
6173 * src/reader.c (grammar_current_rule_action_append): ... here for
6174 consistency with grammar_current_rule_symbol_append.
6175 * tests/regression.at (Braced code in declaration in rules section):
6176 Make yyerror and yylex static as usual.
6177
6178 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
6179
6180 Fix bug that mistakes braced code in a declaration in the rules section
6181 to be a rule action. Mentioned at
6182 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
6183 * src/scan-gram.l: Move midrule action detection from the start of the
6184 scanning of any braced code to...
6185 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
6186 action. For readability, use $2 and @2 rather than the equivalent
6187 global variables.
6188 * tests/regression.at (Braced code in declaration in rules section):
6189 New test to catch the error fixed by the above patch.
6190
6191 Work on code readability some.
6192 * src/scan-code.l (current_rule): Get rid of this misleading and
6193 redundant declaration: it's actually extern'ed in reader.h.
6194 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
6195 translate_action): Add a rule argument and use it instead of the global
6196 current_rule.
6197 (translate_rule_action): This already receives current_rule through an
6198 argument, so pass it on to translate_action instead of assigning
6199 current_rule to current_rule.
6200 (translate_symbol_action, translate_code): Pass rule = NULL to
6201 translate_action.
6202
6203 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
6204
6205 Rename %before-definitions to %start-header and %after-definitions to
6206 %end-header. Don't use these declarations to separate pre-prologue
6207 blocks from post-prologue blocks. Add new order-independent
6208 declarations %before-header and %after-header as alternatives to the
6209 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
6210 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
6211 * NEWS (2.3+): Update for these changes.
6212 * data/glr.c (b4_before_definitions): Update to...
6213 (b4_start_header): ... this.
6214 (b4_after_definitions): Update to...
6215 (b4_end_header): ... this.
6216 * data/glr.cc: Likewise.
6217 * data/lalr1.cc: Likewise.
6218 * data/yacc.c: Likewise.
6219 * doc/bison.texinfo (The prologue): Update names, and replace remaining
6220 prologue blocks with %*-header declarations.
6221 (Calc++ Parser): Likewise.
6222 (Decl Summary): Update names.
6223 (Table of Symbols): Update description.
6224 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
6225 (PERCENT_END_HEADER): ... this.
6226 (PERCENT_BEFORE_DEFINITIONS): Update to...
6227 (PERCENT_START_HEADER): ... this.
6228 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6229 (declaration): Update token names and m4 macro names.
6230 When parsing %end-header and %start-header, invoke translate_code
6231 before muscle_code_grow, and no longer set global booleans to remember
6232 whether these declarations have been seen.
6233 Parse new %after-header and %before-header.
6234 * src/reader.c (before_definitions, after_definitions): Remove.
6235 (prologue_augment): Accept a new bool argument to specify whether to
6236 augment the pre-prologue or post-prologue.
6237 * src/reader.h (before_definitions, after_definitions): Remove these
6238 extern's.
6239 (prologue_augment): Add new bool argument.
6240 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
6241 (PERCENT_END_HEADER): ... this.
6242 (PERCENT_BEFORE_DEFINITIONS): Update to...
6243 (PERCENT_START_HEADER): ... this.
6244 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6245 * tests/actions.at (Printers and Destructors): Update names.
6246
6247 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
6248
6249 Add comparison operators for C++ location classes. Discussed at
6250 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
6251 * data/c++.m4 (b4_define_location_comparison): New boolean %define
6252 declaration indicating whether filename_type has an operator==. If
6253 filename_type is `std::string', it defaults to `1', `0' otherwise.
6254 * data/location.cc: Iff b4_define_location_comparison is `1', add
6255 operator== and operator!= for class position and for class location.
6256
6257 Some minor fixes.
6258 * src/scan-action.l: Remove unused file.
6259 * src/symtab.c (symbol_printer_set): Use printer_location not
6260 destructor_location.
6261 * src/symtab.h (struct symbol): Replace incorrect source comment for
6262 printer members.
6263 * tests/input.at (Incompatible Aliases): Update output with correct
6264 printer location.
6265
6266 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
6267
6268 Don't put the pre-prologue in the header file. For the yacc.c code
6269 file and the glr.c header and code files, move the pre-prologue before
6270 the token definitions. Add new %before-definitions and
6271 %after-definitions to declare code that will go in both the header file
6272 and code file. Discussed at
6273 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
6274 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
6275 and
6276 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
6277 * NEWS (2.3+): Describe these changes.
6278 * data/glr.c (b4_pre_prologue): Move from within to before...
6279 (b4_shared_declarations): ... this.
6280 Add new b4_before_definitions before b4_token_enums.
6281 Add new b4_after_definitions at the end.
6282 * data/glr.cc (b4_pre_prologue): Replace with...
6283 (b4_before_definitions): ... this in the header file.
6284 (b4_after_definitions): New near the end of the header file.
6285 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
6286 code file right before including the header file.
6287 (b4_before_definitions): New in the previous position of
6288 b4_pre_prologue in the header file.
6289 (b4_after_definitions): New near the end of the header file.
6290 * data/yacc.c: Clean up some m4 quoting especially in the header file.
6291 (b4_token_enums_defines): In the code file, move to right before
6292 YYSTYPE for consistency with the header file.
6293 (b4_before_definitions): New right before b4_token_enums_defines in
6294 both the header and code file.
6295 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
6296 header and code file.
6297 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
6298 of prologues for %union dependencies.
6299 (Decl Summary): In %defines description, mention the effect of
6300 %before-definitions and %after-definitions on the header file.
6301 (Calc++ Parser): Forward declare driver in a %before-definitions rather
6302 than in the pre-prologue so that make check succeeds.
6303 (Table of Symbols): Add entries for %before-definitions and
6304 %after-definitions.
6305 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
6306 %before-definitions.
6307 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
6308 (declaration): Parse those declarations and append to
6309 b4_before_definitions and b4_after_definitions, respectively.
6310 * src/reader.c (before_definitions, after_definitions): New bools to
6311 track whether those declarations have been seen.
6312 (prologue_augment): Add to the post-prologue if %union,
6313 %before-definitions, or %after-definitions has been seen.
6314 * src/reader.h (before_definitions, after_definitions): New extern's.
6315 * src/scan-gram.l: Scan the new declarations.
6316 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
6317 prologue block in a %before-definitions or a %after-definitions based
6318 on whether the %union is declared.
6319 * tests/regression.at (Early token definitions with --yacc, Early token
6320 definitions without --yacc): Move tests for token definitions into the
6321 post-prologue since token names are no longer defined in the
6322 pre-prologue.
6323
6324 2006-06-20 Akim Demaille <akim@epita.fr>
6325
6326 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
6327 (symbol_get): Use it.
6328 * src/parse-gram.y: Use it.
6329
6330 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
6331
6332 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
6333 build succeeds when configured with --enable-gcc-warnings.
6334
6335 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6336
6337 * src/parse-gram.y (char_name): New function.
6338 (CHAR, STRING, string_content): For %printer, properly escape.
6339 (ID): Prefer fputs to fprintf.
6340 (id): Reindent to be consistent with other rules.
6341 Properly quote char.
6342
6343 The Translation Project changed its way of publishing translations
6344 to maintainers. I haven't received any responses to my request
6345 for supporting the old way, or for documenting the new way. I
6346 have modified 'bootstrap' to use screen scraping
6347 (in this case, HTML scraping). This is unreliable and inelegant,
6348 but I don't see any better way. Yuck.
6349 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6350 (get_translations): New function, which uses HTML scraping to
6351 deduce locations of latest translations.
6352 Use this function to grab both bison and bison-runtime .po files.
6353 Don't bother priming the pump for the runtime-po domain any more,
6354 as it's now translated better than bison is.
6355
6356 2006-06-19 Akim Demaille <akim@epita.fr>
6357
6358 * src/scan-gram.l: No longer "parse" things after `%union' until
6359 `{'. Rather, return a single "%union" token.
6360 No longer make symbols: return strings, and leave the conversion
6361 to symbols to the parser.
6362 (SC_PRE_CODE, token_type): Remove.
6363 * src/parse-gram.y (%union): New field `character'.
6364 Sort tokens.
6365 (CHAR): New token.
6366 (ID, ID_COLON): Now that the scanner no longer makes them
6367 identifiers, adjust all uses to invoke symbol_get.
6368 (id_colon): New, wraps the conversion from string to symbol.
6369 (%union): Accept a possible union_name.
6370 (symbol): Now can be a char.
6371 * data/c.m4 (b4_union_name): Leave a default value.
6372 * data/glr.c, data/yacc.c: Use it.
6373
6374 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6375
6376 For associating token numbers with token names for "yacc.c", don't use
6377 #define statements unless `--yacc' is specified; always use enum
6378 yytokentype. Most important discussions start at:
6379 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6380 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6381 and
6382 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6383 * NEWS (2.3+): Mention.
6384 * data/c.m4 (b4_yacc_if): New.
6385 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6386 token #define's.
6387 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6388 on token name definitions.
6389 * src/getargs.c (usage): Capitalize `Yacc' in English.
6390 * src/output.c (prepare): Define b4_yacc_flag.
6391 * tests/regression.at (Early token definitions): Test that tokens names
6392 are defined before the pre-prologue not just before the post-prologue.
6393 Remove this test case and copy to...
6394 (Early token definitions with --yacc): ... this to test #define's.
6395 (Early token definitions without --yacc): ... and this to test enums.
6396
6397 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6398
6399 * NEWS: Reword the post-2.3 change to not be so optimistic about
6400 removing the old "look-ahead" spelling.
6401 Update previous look-ahead/lookahead change reports.
6402 * REFERENCES: look-ahead -> lookahead (since that's
6403 what he actually wrote).
6404 * doc/refcard.tex: look ahead -> lookahead,
6405 look-ahead -> lookahead
6406
6407 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6408
6409 For consistency, use `lookahead' instead of `look-ahead' or
6410 `look_ahead'. Discussed starting at
6411 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
6412 and then at
6413 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.
6414 * NEWS: For the next release, note the change to `--report'.

6479
6480 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
6481
6482 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
6483
6484 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
6485
6486 * TODO: Add request from Nelson H. F. Beebe to be able to install
6487 Bison without installing the yacc script.
6488
6489 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6490
6491 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
6492 and yytext if they're already #define'd.
6493 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
6494 * src/scan-code-c.c: ... here.
6495 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
6496 <config.h>.
6497
6498 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6499
6500 Get Bison to build again when configured with --enable-gcc-warnings.
6501 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
6502 missing #include's.
6503 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
6504 loc argument as it shadows a global.
6505 * src/scan-gram.l: Remove stray comma that prevents boundary_set
6506 invocation.
6507
6508 * src/.cvsignore: Add scan-code.c.
6509
6510 2006-06-07 Akim Demaille <akim@epita.fr>
6511
6512 * src/scan-gram.l: Move the "add a trailing ; to actions" code
6513 to...
6514 * src/scan-code.l: here.
6515 * tests/input.at (Torturing the Scanner): Fix another location
6516 error.
6517
6518 2006-06-07 Akim Demaille <akim@epita.fr>
6519
6520 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
6521
6522 2006-06-06 Akim Demaille <akim@epita.fr>
6523
6524 Extract the parsing of user actions from the grammar scanner.
6525 As a consequence, the relation between the grammar scanner and
6526 parser is much simpler. We can also split "composite tokens" back
6527 into simple tokens.
6528 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
6529 * src/scan-gram.l (add_column_width, adjust_location): Move to and
6530 rename as...
6531 * src/location.h, src/location.c (add_column_width)
6532 (location_compute): these.
6533 Fix the column count: the initial column is 0.
6534 (location_print): Be robust to ending column being 0.
6535 * src/location.h (boundary_set): New.
6536 * src/main.c: Adjust to scanner_free being renamed as
6537 gram_scanner_free.
6538 * src/output.c: Include scan-code.h.
6539 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
6540 Use boundary_set.
6541 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
6542 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
6543 which is now, again, a separate token.
6544 Adjust all dependencies.
6545 Whereever actions with $ and @ are used, use translate_code.
6546 (action): Remove this nonterminal which is now useless.
6547 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
6548 (grammar_current_rule_action_append): Use translate_code.
6549 (packgram): Bound check ruleno, itemno, and rule_length.
6550 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
6551 (last_string, last_braced_code_loc, max_left_semantic_context)
6552 (scanner_initialize, scanner_free, scanner_last_string_free)
6553 (gram_out, gram_lineno, YY_DECL_): Move to...
6554 * src/scan-gram.h: this new file.
6555 (YY_DECL): Rename as...
6556 (GRAM_DECL): this.
6557 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
6558 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6559 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6560 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6561 Move these declarations, and...
6562 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
6563 these to...
6564 * src/flex-scanner.h: this new file.
6565 * src/scan-gram.l (rule_length, rule_length_overflow)
6566 (increment_rule_length): Remove.
6567 (last_braced_code_loc): Rename as...
6568 (gram_last_braced_code_loc): this.
6569 Adjust to the changes of the parser.
6570 Move all the handling of $ and @ into...
6571 * src/scan-code.l: here.
6572 * src/scan-gram.l (handle_dollar, handle_at): Remove.
6573 (handle_action_dollar, handle_action_at): Move to...
6574 * src/scan-code.l: here.
6575 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
6576 scan-code.h, scan-code-c.c, scan-gram.h.
6577 (EXTRA_bison_SOURCES): Add scan-code.l.
6578 (BUILT_SOURCES): Add scan-code.c.
6579 (yacc): Be robust to white spaces.
6580
6581 * tests/conflicts.at, tests/input.at, tests/reduce.at,
6582 * tests/regression.at: Adjust the column numbers.
6583 * tests/regression.at: Adjust the error message.
6584
6585 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6586
6587 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6588 Use Akim's wording from
6589 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
6590
6591 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6592
6593 Between Bison releases, manually append `+' to the previous Bison
6594 release number, and use that as a signal to automatically print the
6595 ChangeLog's CVS Id keyword from --version. Discussed starting at
6596 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
6597 * ChangeLog: Add Id header.
6598 * configure.ac (AC_INIT): Append `+' to `2.3'.
6599 * src/.cvsignore: Add revision.c.
6600 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
6601 (BUILT_SOURCES): Add revision.c.
6602 (revision.c): New target rule. This file defines a new global variable
6603 named revision. It initializes it with either the Id from ChangeLog
6604 or, if VERSION doesn't contain `+', with the empty string.
6605 * src/getargs.c (version): Print the value of revision.
6606 * src/revision.h: Extern revision.
6607
6608 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
6609
6610 * NEWS: Version 2.3.
6611 * configure.ac (AC_INIT): Likewise.
6612
6613 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
6614
6615 * data/glr.c (YYRECOVERING): Define to be a function-like macro
6616 with no arguments, not as an object-like macro. This is for
6617 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
6618 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
6619 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
6620 Document this.
6621
6622 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
6623
6624 * src/getargs.c (usage): Back out yesterday's modification of the
6625 --help output so that we don't have to wait for translation before
6626 releasing 2.3.
6627
6628 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
6629
6630 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
6631 Problem reported by Akim Demaille.
6632
6633 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6634
6635 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6636
6637 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6638
6639 * data/yacc.c (yy_reduce_print): Omit trailing white space in
6640 generated source code. Problem reported by Frans Englich in
6641 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
6642
6643 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
6644
6645 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
6646 shell, not within 'make', so that 'make' by an ordinary builder
6647 (using GNU make) does not worry about configuring gzip. This also
6648 works around a bug reported independently by Keith Thompson and by
6649 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
6650 stderr rather than stdout, messing up the build logs.
6651
6652 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6653
6654 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
6655 to make sure that YYID will never be unused. This fixes a 'make
6656 maintainer-check' failure caused by the recent changes to the 'Trivial
6657 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
6658 not used.
6659 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
6660
6661 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6662
6663 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
6664 state before an empty RHS is always resolved here. Only the location
6665 of that state is guaranteed to be resolved, and that's enough. This
6666 fixes the remaining bug reported by Derek M. Jones in
6667 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6668 * tests/glr-regression.at (Uninitialized location when reporting
6669 ambiguity): Test the above case.
6670 Also, the embedded comments in this test case claim it checks the case
6671 of an empty RHS that has inherited the initial location. However, the
6672 corresponding LHS was already resolved, so yyresolveLocations didn't
6673 actually have reason to modify it. Fix this by forcing
6674 nondeterministic operation at the beginning of the parse.
6675
6676 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6677
6678 * data/c.m4 (b4_yy_symbol_print_generate):
6679 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
6680 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
6681 of the bugs reported today by Derek M Jones in
6682 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6683 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
6684 defined to be a type name without parens or brackets.
6685 (Location Type): Similarly for YYLTYPE.
6686 * tests/regression.at (Trivial grammars): Put in a test for this
6687 bug that will be caught by 'make maintainer-check' (though not,
6688 alas, by 'make check' unless your compiler is picky).
6689
6690 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6691
6692 * NEWS: Version 2.2.
6693 * configure.ac (AC_INIT): Likewise.
6694
6695 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
6696
6697 * data/glr.c (yyreportTree): Make room in yystates for the state
6698 preceding the RHS. This fixes the segmentation fault reported by Derek
6699 M. Jones in
6700 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
6701 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
6702 to the user. Reported for yyreportTree by Derek M. Jones later in the
6703 same thread.
6704 * THANKS: Add Derek M. Jones.
6705 Update my email address.
6706 Fix typo in Steve Murphy's name.
6707
6708 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6709
6710 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
6711 checking against YYLAST that caused the parser to miss a potential
6712 alternative in its diagnostic.
6713 Problem reported by Maria Jose Moron Fernandez in
6714 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
6715 * data/lalr1.cc (yysyntax_error_): Likewise.
6716 * data/yacc.c (yysyntax_error): Likewise.
6717 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
6718 tokens, in case we run into an older C compiler.
6719 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
6720 Use them to check for the off-by-one error fixed above.
6721
6722 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
6723 YYSIZE_T, not size_t.
6724 * tests/regression.at (Trivial grammars): New test, to catch
6725 the error fixed by the above patch.
6726
6727 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6728
6729 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
6730 scheme.
6731 Reported by Steve Murphy.
6732
6733 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6734
6735 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
6736 * data/glr.cc: b4_location_flag is now b4_locations_flag.
6737
6738 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6739
6740 Implement --trace=m4.
6741 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
6742 * src/output.c (output_skeleton): When set, pass -dV to m4.
6743
6744 Factor the handling of flags in m4.
6745 * src/output.c (prepare): Rename the muscle names debug, defines,
6746 error_verbose to debug_flag, defines_flag, error_verbose_flag.
6747 * data/c.m4: Adjust.
6748 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
6749 Use b4_define_flag_if to define other b4_FLAG_if macros.
6750 (b4_location_if): As a consequence, rename as...
6751 (b4_locations_if): this, for consistency.
6752 Adjust all the skeletons.

6756 * etc/bench.pm: Shorten bench names.
6757
6758 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6759
6760 * src/output.h, src/output.c (error_verbose): Move to...
6761 * src/getargs.h, src/getargs.c: here.
6762 Sort the flags.
6763 Adjust dependencies.
6764
6765 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6766
6767 * data/c.m4 (b4_copyright): Put the special exception for Bison
6768 skeletons here, so we don't have to put it in each skeleton. All
6769 uses changed. Suggested by Akim Demaille. Also, wrap the
6770 copyright notice, in case it is longer than 80 columns. Replace
6771 comma by newline after title.
6772
6773 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6774
6775 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
6776 incompatibility, not a bug. Mention that it wasn't fixed as of
6777 flex 2.5.33.
6778
6779 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6780
6781 * examples/extexi: Enforce the precedence of concatenation over
6782 >>.
6783 Reported by Tommy Nordgren.
6784
6785 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6786
6787 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
6788 with the member "token".
6789 Reported by Martin Nylin.
6790
6791 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
6792
6793 * data/glr.c: Switch to Bison 2.2 special-exception language in
6794 the copyright notice. Use more-regular format for titles and
6795 copyright notices.
6796 * data/glr.cc: Likewise.
6797 * data/location.cc: Likewise.
6798 * data/yacc.cc: Likewise.
6799 * doc/bison.texinfo (Conditions): Document this.
6800 * NEWS: likewise. Upgrade version to 2.2.
6801
6802 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
6803
6804 * data/glr.cc: Remove dead code.
6805
6806 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6807
6808 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
6809 that variable and the line breaks the bootstrap. Problem reported
6810 by Juan M. Guerrero.
6811
6812 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
6813

6819
6820 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
6821
6822 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
6823 rule.
6824 Reported by Mickael Labau.
6825 * tests/input.at (Torturing the Scanner): Test it.
6826
6827 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
6828
6829 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
6830 Problem reported by Bob Rossi.
6831
6832 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
6833
6834 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
6835 and didn't really work.
6836 For the index, use @ifnotinfo, not @iftex.
6837 Minor cleanups of spacing and terminology.
6838
6839 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6840
6841 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
6842 of AT_NAME_PREFIX when %name-prefix is not used.
6843
6844 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6845
6846 Apply --prefix to C++ skeletons too: they change the namespace.
6847 The test suite already exercize these cases.
6848 * data/c++.m4 (b4_namespace): New.
6849 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
6850 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
6851 * data/yacc.c, data/glr.c: Remove a useless `[]'.
6852 * doc/bison.texinfo: Document it.
6853 (Option Cross Key): Use @multitable in all formats. It looks
6854 nicer, even in TeX outputs.
6855 (Rules): Use the same code whatever the output type is.
6856 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
6857 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
6858 * tests/calc.at: Use it, instead of hard coding `yy'.

6865
6866 * doc/FAQ: Remove, merged into...

6868 * doc/Makefile.am (EXTRA_DIST): Adjust.
6869
6870 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
6871
6872 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
6873 even if empty.
6874 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
6875 * doc/bison.texinfo (Calc++ Scanner): Use it.
6876
6877 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
6878
6879 Fix two nits reported by twlevo, plus one more that I discovered.
6880
6881 * src/assoc.h (assoc_to_string): Give a name to the arg, as
6882 this is the usual Bison style.
6883 * src/location.h (location_print): Likewise.
6884
6885 * src/reader.h (token_name): Likewise.
6886
6887 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
6888
6889 Fix some nits reported by twlevo.
6890 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
6891 and "POSIX". Use more-modern syntax for URLs. Mention C++
6892 and ask for Java. Don't hardwire OS version numbers. Add
6893 copyright notice.
6894 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
6895 * src/conflicts.c (solved_conflicts_obstack): Now static.
6896
6897 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
6898
6899 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
6900 page. Say "you can use it" not "you may use it" as on the web page;
6901 we're describing capabilities not granting permission.
6902
6903 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
6904
6905 * data/glr.c (yyresolveLocations): Rename local variables to avoid
6906 shadowing warnings. Use usual patter for iterating through RHS.
6907 * tests/glr-regression.at
6908 (Uninitialized location when reporting ambiguity):
6909 Modify yylex so that it uses its argument, rather than trying
6910 to rely on ARGSUSED (which doesn't work for gcc with warnings).
6911 const char -> char const.
6912
6913 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
6914 Don't use tabs inside commands; it messes up 'ps'.
6915 Problem reported by twlevo.
6916
6917 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
6918
6919 * tests/glr-regression.at (Uninitialized location when reporting
6920 ambiguity): New test case.
6921 * data/glr.c (yyresolveLocations): New function, which uses
6922 YYLLOC_DEFAULT.
6923 (yyresolveValue): Invoke yyresolveLocations before reporting an
6924 ambiguity.
6925 * doc/bison.texinfo (Default Action for Locations): Note
6926 YYLLOC_DEFAULT's usage for ambiguity locations.
6927 (GLR Semantic Actions): Cross-reference those notes.
6928
6929 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
6930
6931 * tests/glr-regression.at (Leaked semantic values when reporting
6932 ambiguity): Remove unnecessary union and type declarations.
6933 (Leaked lookahead after nondeterministic parse syntax error): New test
6934 case.
6935 * data/glr.c (yyparse): Check for zero stacks remaining before
6936 attempting to shift the lookahead so that you don't lose it.
6937
6938 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6939
6940 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
6941 * tests/glr-regression.at (Leaked semantic values when reporting
6942 ambiguity): New test case.
6943 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
6944 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
6945 now unnecessary yystackp parameter.
6946 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
6947 destructors can be called.
6948
6949 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
6950 in existing testcases.
6951
6952 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6953
6954 Don't leak semantic values for parent RHS when a user action cuts the
6955 parser, and clean up related code a bit.
6956 * tests/glr-regression.at (Leaked merged semantic value if user action
6957 cuts parse): Rename to...
6958 (Leaked semantic values if user action cuts parse): ... this. Add check
6959 for leaked parent RHS values.
6960 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
6961 between an unresolved state (non-empty chain of semantic options) and
6962 an incomplete one (signaled by an empty chain).
6963 (yyresolveStates): Document the interface. Move all manipulation of a
6964 successfully or unsuccessfully resolved yyGLRState to...
6965 (yyresolveValue): ... here so that yyresolveValue always leaves a
6966 yyGLRState with consistent data and thus is easier to understand.
6967 Remove the yyvalp and yylocp parameters since they are always just
6968 taken from the yys parameter. When reporting a discarded merged value
6969 in debugging output, note that it is incompletely merged. Document the
6970 interface.
6971 (yyresolveAction): If resolving any of the RHS states fails, destroy
6972 them all rather than leaking them. Thus, as long as user actions are
6973 written to clean up the RHS correctly, yyresolveAction always cleans up
6974 the RHS of a semantic option. Document the interface.
6975
6976 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
6977
6978 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
6979 led to a segmentation fault in GNU Pascal. Problem reported
6980 by Waldek Hebisch.
6981
6982 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
6983
6984 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
6985 mid-rule action inside a nonterminal symbol in order to declare a
6986 destructor for its semantic value.
6987
6988 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>

6992 __cplusplus && ! defined _STDLIB_H && !
6993 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
6994 defined free))]: Include <stdlib.h> rather than rolling our own
6995 declarations of malloc and free, to avoid problems with
6996 incompatible declarations (using 'throw') C++'s stdlib.h. This
6997 should fix Debian bug 340012
6998 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,

7028 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
7029 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
7030 messes up because C++ code is compiled in 32-bit mode but linked
7031 in 64-bit mode.

7038 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
7039
7040 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
7041 nodist_PROGRAMS, since we don't need to actually compile the
7042 example if we're just doing a plain 'make'. This avoids bothering
7043 the installer unnecessarily about problems due to weird C++
7044 compilers.

7047
7048 More portability fixes for problems summarized by Nelson H. F. Beebe.
7049
7050 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
7051 than #include "...", and compile with -I'.'. The old method was
7052 not portable, according to Posix and the C standard, and it does
7053 not work with Sun C 5.7, where previous #line directives affect
7054 the working directory used in later #include "..." directives.

7073 that '#include <string>' works.
7074
7075 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
7076 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
7077 "warning: sorry: semantics of inline function static data `const
7078 unsigned char translate_table[262]' are wrong (you'll wind up with
7079 multiple copies)".
7080
7081 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
7082 or, xor to not_, and_, or_, and xor_, respectively. This works
7083 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
7084 random system header somewhere that includes the equivalent of
7085 <iso646.h>.
7086
7087 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
7088 -E" works; it apparently doesn't work with PathScale EKO Compiler
7089 Suite Version 2.0.

7092
7093 During deterministic GLR operation, user actions should be able to
7094 influence the parse by changing yychar. To make this easier to fix and
7095 to make glr.c easier to evolve in general, don't maintain yytoken in
7096 parallel with yychar; just compute yytoken when needed.
7097 * tests/glr-regression.at (Incorrect lookahead during deterministic
7098 GLR): Check that setting yychar in a user action has the intended
7099 effect.
7100 * data/glr.c (yyGLRStack): Remove yytokenp member.
7101 (yyclearin): Don't set *yytokenp.
7102 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
7103 yychar rather than *yytokenp to determine the current lookahead.
7104 Compute yytoken locally when needed.
7105 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
7106 point to.
7107
7108 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
7109 after `--report' documentation.

7111 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
7112
7113 * src/parse-gram.y (grammar_declaration): Location of printer
7114 symbol is @1, not list->location. Bug reported by twlevo.
7115 * tests/input.at (Incompatible Aliases): Adjust to above change.
7116
7117 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
7118
7119 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
7120 all the test at once. This makes the output easier to read in the
7121 normal case.
7122
7123 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7124 got from <http://bro-ids.org/download.html>. The bug is that
7125 when two actions appeared in succession, the second one was
7126 scanned before the first one was added to the grammar rule
7127 as a midrule action. Bison then output the incorrect warning
7128 "parse.y:905.17-906.36: warning: unused value: $3".
7129 * src/parse-gram.y (BRACED_CODE, action): These are no longer
7130 associated with a value.
7131 (rhs): Don't invoke grammar_current_rule_action_append.
7132 (action): Invoke it here instead.
7133 * src/reader.c (grammar_midrule_action): Now extern.
7134 (grammar_current_rule_action_append): Don't invoke
7135 grammar_midrule_action; that is now the scanner's job.
7136 * src/reader.h (last_string, last_braced_code_loc):
7137 (grammar_midrule_action): New decls.
7138 * src/scan-gram.l (last_string): Now extern, sigh.
7139 (last_braced_code_loc): New extern variable.
7140 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
7141 rule already has an action.
7142 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
7143 * tests/input.at (AT_CHECK_UNUSED_VALUES):
7144 Add some tests to check that the above changes fixed the bug.
7145
7146 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
7147
7148 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
7149 All used changed. Check whether the symbol has a destructor,
7150 not whether it is typed.
7151 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
7152 that the values are still reported as unused. All line numbers
7153 adjusted.
7154
7155 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
7156
7157 Work around a bug in bro 0.8, which underparenthesizes its
7158 definition of YYLLOC_DEFAULT.
7159 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
7160 their arguments.
7161 * data/lalr1.cc: Likewise.
7162 * data/yacc.cc: Likewise.
7163
7164 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
7165
7166 Work around a bug in Pike 7.0, and give the Pike folks a
7167 better way to override the usual int widths.
7168 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
7169 user can override the types.
7170 (short): #undef, to work around a bug in Pike 7.0.
7171 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
7172 (union yyalloc.yyss): Use yytype_int16 rather than short.
7173 All uses changed.
7174 (yysigned_char): Remove.
7175 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
7176 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
7177 * tests/regression.at (Web2c Actions): Adjust to above changes.
7178
7179 * src/reader.c (check_and_convert_grammar): New function.
7180 (reader): Close the input file even if something went wrong during
7181 parsing. Minor file descriptor leak reported by twlevo.
7182
7183 * src/assoc.c (assoc_to_string): Use a default: abort (); case
7184 to pacify gcc -Wswitch-default.
7185 * src/scan-gram.l (adjust_location): Use a default: break; case

7197

7253

7300 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
7301 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
7302 for the benefit of some pre-C99 compilers.
7303
7304 * bootstrap: Undo changes to gnulib files that autoreconf made.
7305
7306 Minor fixups to get 'make maintainer-check' to work.
7307 * configure.ac: Don't use -Wnested-externs, as it's incompatible
7308 with the new verify.h implementation.

7329
7330 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial

7351 (changelog-check): Don't require version number near head.
7352 (copyright-check): Use current year instead of hardwiring 2005.
7353 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
7354 (announcement): Add --gpg-key-ID.
7355
7356 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
7357 with "file system".
7358
7359 Avoid undefined behavior that addressed just before the start of an
7360 array. Problem reported by twlevo.
7361 * src/reader.c (packgram): Prepend a new sentinel before ritem.
7362 * src/lalr.c (build_relations): Rely on new sentinel.
7363 * src/gram.c (gram_free): Adjust to new sentinel.
7364

7373
7374 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7375
7376 * data/glr.c (yysplitStack): A little stylistic rewrite.
7377
7378 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7379
7380 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
7381
7382 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
7383
7384 * doc/bison.texinfo: Fix some typos.
7385 (GLR Semantic Actions): New subsection discussing special
7386 considerations because GLR semantic actions might be deferred.
7387 (Actions): Mention look-ahead usage of yylval.
7388 (Actions and Locations): Mention look-ahead usage of yylloc.
7389 (Special Features for Use in Actions): Add YYEOF entry and mention it
7390 in the yychar entry.
7391 In the yychar entry, remove mention of the local yychar case (pure
7392 parser) since this is irrelevant information when writing semantic
7393 actions and since it's already discussed in `Table of Symbols' where
7394 yychar is otherwise described as an external variable.
7395 In the yychar entry, don't call it the `current' look-ahead since it
7396 isn't when semantic actions are deferred.
7397 In the yychar and yyclearin entries, add note about deferred semantic
7398 actions.
7399 Add yylloc and yylval entries discussing look-ahead usage.
7400 (Look-Ahead Tokens): When discussing yychar, don't call it the
7401 `current' look-ahead, and do mention yylval and yylloc.
7402 (Error Recovery): Cross-reference `Action Features' when mentioning
7403 yyclearin.
7404 (Table of Symbols): In the yychar entry, don't call it the `current'
7405 look-ahead.
7406 In the yylloc and yylval entries, mention look-ahead usage.
7407
7408 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7409
7410 * tests/glr-regression.at: Update copyright year to 2006.
7411
7412 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7413
7414 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
7415 use during nondeterministic operation to track which stacks have
7416 actually needed the current lookahead.
7417 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
7418 Allocate, deallocate, resize, and otherwise shuffle space for
7419 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
7420 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
7421 appropriately during nondeterministic operation.
7422 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
7423 members to store the current lookahead to be used by the deferred
7424 user action.
7425 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
7426 from which the RHS is taken. Set the lookahead members of the new
7427 yySemanticOption according to the lookahead status for stack yyk.
7428 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
7429 yyaddDeferredAction.
7430 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
7431 members of yySemanticOption before invoking yyuserAction, and then set
7432 them back to their current values afterward.
7433 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
7434 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
7435 * tests/glr-regression.at: Remove `.' from the ends of recent test case
7436 titles for consistency.
7437 (Leaked merged semantic value if user action cuts parse): In order to
7438 suppress lint warnings, use arguments in merge function, and assign
7439 char value < 128 in main.
7440 (Incorrect lookahead during deterministic GLR): New test case.
7441 (Incorrect lookahead during nondeterministic GLR): New test case.
7442
7443 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7444
7445 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
7446 !yyvaluep as signal that no semantic value is available to print.
7447 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
7448 to print a semantic value.
7449
7450 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7451
7452 * tests/glr-regression.at: For consistency with my newer test cases,
7453 don't thank myself.
7454
7455 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7456
7457 * data/glr.c (yyresolveValue): When merging semantic options, if at
7458 least one user action succeeds but a later one cuts the parse, then
7459 destroy the semantic value before returning rather than leaking it.
7460 (yyresolveStates): If a user action cuts the parse and thus
7461 yyresolveValue fails, ignore the (unset) semantic value rather than
7462 corrupting the yyGLRState, and empty the semantic options list since
7463 the user actions should have called all necessary destructors.
7464 Simplify code with YYCHK.
7465 * tests/glr-regression.at (Corrupted semantic options if user action
7466 cuts parse): New test case.
7467 (Undesirable destructors if user action cuts parse): New test case.
7468 Before applying any of this patch, this test case never actually failed
7469 for me... but only because the corrupted semantic options usually
7470 masked this bug.
7471 (Leaked merged semantic value if user action cuts parse): New test
7472 case.
7473
7474 2006-01-05 Akim Demaille <akim@epita.fr>
7475
7476 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/.

7479
7480 * data/c.m4 (b4_c_modern): New macro, with a new provision for

7483 * data/yacc.c (YYMODERN_C): Remove. All uses replaced by
7484 b4_c_modern.
7485 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
7486 than rolling our own.
7487
7488 2006-01-04 Akim Demaille <akim@epita.fr>
7489
7490 Also warn about non-used mid-rule values.

7492 member.
7493 (symbol_list_new): Adjust.

7495 (grammar_rule_check): Use it.
7496 (grammar_midrule_action): Bind a mid-rule LHS to its rule.

7499 Use it.
7500 * tests/actions.at (Exotic Dollars): Adjust.
7501
7502 2006-01-04 Akim Demaille <akim@epita.fr>
7503
7504 * src/reader.c (grammar_midrule_action): If $$ is set in a
7505 mid-rule, move the `used' bit to its lhs.
7506 * tests/input.at (Unused values): New.
7507 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
7508
7509 2006-01-03 Paul Eggert <eggert@cs.ucla.edu>
7510
7511 * doc/bison.texinfo (Bison Options): Say more accurately what
7512 --yacc does.
7513 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
7514 about declarations in the grammar when in Yacc mode, as POSIX does
7515 not require a diagnostic when the grammar uses extensions.
7516
7517 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
7518
7519 Warn about dubious constructions like "%token T T".
7520 Reported by twlevo.
7521 * src/symtab.h (struct symbol.declared): New member.
7522 * src/symtab.c (symbol_new): Initialize it to false.
7523 (symbol_class_set): New arg DECLARING, specifying whether
7524 this is a declaration that we want to warn about, if there
7525 is more than one of them. All uses changed.
7526
7527 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
7528 Allow multiple %union directives, whose contents concatenate.
7529 * src/parse-gram.y (grammar_declaration): Likewise.
7530 Use muscle_code_grow, so that we don't need stype_line any more.
7531 All uses changed.
7532
7533 * src/muscle_tab.c (muscle_grow): Fix comment.
7534
7535 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:
7536 * data/yacc.c, src/getargs.c, src/output.c, tests/cxx-type.at:
7537 Update copyright year to 2006.
7538
7539 2006-01-03 Akim Demaille <akim@epita.fr>
7540
7541 Have glr.cc pass (some of) the calc.at tests.
7542 * data/glr.cc (b4_parse_param_orig): New.
7543 (b4_parse_param): Improve its definition, and bound it more
7544 clearly in the skeleton.
7545 (b4_epilogue): Append, instead of prepending, in order to keep
7546 #line consistency.
7547 Simplify the generation of auxiliary functions: locations and
7548 purity are mandated.
7549 (b4_global_tokens_and_yystype): Honor it.
7550 * data/location.cc (c++.m4): Don't include it.
7551 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF

7555 Be sure to initialize the first position's filename.
7556 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
7557 mandated anyway.
7558 (AT_CHECK_CALC_GLR_CC): New.
7559 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
7560
7561 2006-01-02 Akim Demaille <akim@epita.fr>
7562
7563 * src/output.c (output_skeleton): Don't hard wire the inclusion of
7564 c.m4.
7565 * data/c++.m4, data/glr.c, data/yacc.c: Include c.m4.
7566 * data/glr.cc: Do not include stack.hh.

7572 * tests/cxx-type.at: Reformat whitespace with tabs.
7573 (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo

7575
7576 2005-12-29 Akim <akim@sulaco.local>
7577
7578 Let glr.cc catch up with symbol_value_print.

7582
7583 2005-12-28 Paul Eggert <eggert@cs.ucla.edu>
7584
7585 * src/location.h (boundary): Note that a line or column equal
7586 to INT_MAX indicates an overflow.
7587 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
7588 (rule_length_overflow, increment_rule_length, add_column_width):
7589 New functions.
7590 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
7591 (<SC_BRACED_CODE>"}"):
7592 Use increment_rule_length rather than incrementing it by hand.
7593 (adjust_location, handle_syncline): Diagnose overflow.
7594 (handle_action_dollar, handle_action_at):
7595 Fix bug with monstrosities like $-2147483648.

7609
7610 2005-12-27 Akim Demaille <akim@epita.fr>
7611
7612 * src/reader.c (grammar_current_rule_check): Also check that $$
7613 is used.
7614 Take the rule to check as argument, hence rename as...
7615 (grammar_rule_check): this.
7616 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
7617 Rename as...
7618 (grammar_rule_begin, grammar_rule_end): these, for consistency.
7619 (grammar_midrule_action, grammar_symbol_append): Now static.
7620 * tests/torture.at (input): Don't rely on the default action
7621 being always performed.

7662 2005-12-21 Paul Eggert <eggert@cs.ucla.edu>
7663
7664 Undo 2005-12-01 tentative license wording change. The wording is
7665 still being reviewed by the lawyers, and we don't want to wait for
7666 them before publishing a test release. For now, revert to the
7667 previous wording.
7668 * NEWS: Undo 2005-12-01 change.
7669 * data/glr.c: Revert to previous license wording.
7670 * data/glr.cc: Likewise.
7671 * data/lalr1.cc: Likewise.
7672 * data/location.cc: Likewise.
7673 * data/yacc.c: Likewise.
7674

7678 * data/lalr1.cc: Likewise.
7679 * data/yacc.c: Likewise.
7680 * data/yacc.c: Reformat comments slightly.

7685
7686 2005-12-21 Joel E. Denny <address@hidden>
7687
7688 * tests/cxx-type.at: Construct a tree, count the parents of shared
7689 nodes, and free each node once and only once. Previously, the memory
7690 for semantic values was leaked instead.
7691
7692 2005-12-21 Joel E. Denny <address@hidden>
7693
7694 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
7695 (yylval, yylloc): If pure, #define to yystackp->yyval and
7696 yystackp->yyloc similar to yychar and yynerrs.
7697 (yyparse): If pure, remove local yylval and yylloc. Add local
7698 yystackp to accommodate pure definitions of yylval and yylloc.
7699 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
7700 yylvalp and yyllocp to &yylval and &yylloc.
7701 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
7702 namespace. Previously, nerrs and char were missing, but lval and lloc
7703 weren't necessary.
7704 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
7705 yylvalp and yyllocp parameters since, if pure, these are now always
7706 accessible through yystackp. If not pure, they are still accessible
7707 globally.
7708 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
7709 `if (YYID (N))' to pacify lint.
7710
7711 2005-12-21 Akim Demaille <akim@epita.fr>
7712
7713 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
7714 destroy the RHS symbols of a rule.
7715 * data/yacc.c (yylen): Initialize to 0.
7716 Keep its value to the number of items to possibly shift.
7717 In particular, a regular successful parse that ends on YYFINAL by
7718 a (internal) YYACCEPT must not have yylen != 0.
7719 (yyerrorlab, yyreturn): Pop the RHS.
7720 Reorder a bit to emphasize the `shifting' bits of code.
7721 (YYPOPSTACK): Now accept a number of items to pop.

7731 * djgpp/config.bat: Replace every occurence of the file name
7732 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
7733 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
7734 * djgpp/config.sed: Replace every occurence of the file name
7735 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

7737 * djgpp/djunpack.bat: DJGPP specific file.
7738 * djgpp/fnchange.lst: DJGPP specific file.
7739 * djgpp/README.in: Add new information about how to unpack the bison

7750
7751 * data/glr.c: Reorder typedef declarations for structs to match order
7752 of struct declarations.
7753 Rename yystack everywhere to yystackp except in yyparse where it's not

7756 consistency.
7757 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
7758 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
7759 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
7760 lint.

7763
7764 * tests/sets.at (Accept): Fix typos in regular expression used to
7765 sed out the final state number.
7766
7767 Work around portability problem on Solaris 10: flex-generated
7768 files include <stdio.h> before <config.h>, which messes up
7769 because the latter defines __EXTENSIONS__. Address the problem
7770 by creating two new little files that include <config.h> first,
7771 then include the flex-generated files. Rewrite everyone else
7772 to include <config.h> first, as well.
7773 * lib/timevar.c: Always include "config.h".
7774 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

7810
7811 Cleanups so that Bison-generated parsers have less lint.
7812 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
7813 Prepend /*ARGSUSED*/, for lint's sake.
7814 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
7815 definition if 'lint' is defined.
7816 (YYID): New macro (or function, if lint).
7817 All uses of /*CONSTCOND*/0 replaced by YYID(0).
7818 * data/yacc.c: Likewise.
7819 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
7820 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
7821 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
7822 is C++ only.
7823 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.

7841 New test case.
7842 (Duplicated user destructor for lookahead): This test now is expected
7843 to succeed.
7844
7845 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
7846
7847 * NEWS: Document the following change.
7848 * data/yacc.c: Say "parser skeleton" rather than "file", since
7849 it's no longer just a file.
7850 * data/glr.c: Grant a special exception for C GLR parsers, that
7851 reads like the already-existing exception for C LALR(1) parsers.
7852 * data/glr.cc: Likewise.
7853 * data/lalr1.cc: Likewise.
7854 * data/location.cc: Likewise.

7862
7863 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
7864 Fix typos in previous change that broke 'make check'.
7865 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
7866 supported in C.
7867 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
7868 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
7869 We can revert this once things settle down.
7870
7871 * src/conflicts.c (conflicts_print): Don't print file name twice
7872 when %expect fails because there were no conflicts.
7873 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
7874 change.
7875 * tests/conflicts.at (%expect not enough, %expect too much):
7876 (%expect with reduce conflicts): Adjust to new behavior.

7899
7900 2005-11-14 Akim Demaille <akim@epita.fr>
7901
7902 * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
7903 from 1 to N, while values and location start at 0.
7904 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
7905

7933 * data/lalr1.cc (b4_location_constructors): Define it for backward
7934 compatibility.

7944
7945 Have glr.c include its header file when created.

8008
8009 * bootstrap (cleanup_gnulib): New function. Use it to clean up
8010 gnulib when interrupted. This fixes some race conditions and
8011 works around some portability problems (one noted by Paul
8012 Hilfinger).

8031 Finish the transition config -> build-aux.
8032 * configure.ac, Makefile.am: Use build-aux.
8033 * config/prev-version, config/announce-gen, config/Makefile.am:
8034 Move to...
8035 * build-aux/prev-version, build-aux/announce-gen,
8036 * build-aux/Makefile.am: here.
8037
8038 2005-10-14 Akim Demaille <akim@epita.fr>
8039
8040 * examples/calc++/test: Use set -x only when VERBOSE.
8041
8042 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
8043
8044 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
8045 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
8046
8047 2005-10-13 Akim Demaille <akim@epita.fr>
8048
8049 * src/scan-skel.l: Output the base name parts of the parser and
8050 header file names.
8051 * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
8052 additional checks.
8053 Use this to exercise C++ outputs in subdirs.
8054 Reported by Oleg Smolsky.
8055
8056 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
8057
8058 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
8059 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
8060 Problem reported by John P. Hartmann.
8061 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
8062 already defined it.
8063
8064 2005-10-12 Akim Demaille <akim@epita.fr>
8065
8066 * src/parse-gram.y (version_check): Exit 63 to please missing
8067 (stands for "version mismatch).
8068 * tests/input.at, doc/bison.texinfo: Adjust.

8073 (xlc and xlC_r) reported by John P. Hartmann.
8074 * data/location.cc (initial_column, initial_line): Remove.
8075 All uses replaced by 0 and 1.
8076 * src/scan-gram.l (gram_wrap): Redefine to avoid bug in flex 2.5.31
8077 that xlc complains about.
8078 * src/scan-skel.l (skel_wrap): Likewise.
8079 * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
8080 as __STDC__.
8081 * data/yacc.c (YYMODERN_C): New macro, which also looks at
8082 __STDC_VERSION__. Use it everywhere instead of looking at
8083 __STDC__ and __cplusplus.
8084
8085 2005-10-10 Akim Demaille <akim@epita.fr>
8086
8087 * examples/calc++/test: Be quiet unless VERBOSE.

8092 Use YYUSE instead of casting to void.
8093 * data/glr.c (YYUSE): New macro.
8094 (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
8095 Use it instead of rolling our own.

8097 (YYCHK1):
8098 Use /*CONSTCOND*/ to suppress lint warnings.
8099 * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
8100 (YY_STACK_PRINT): Use 'false' not '0'.

8105 (YYDPRINTF, YY_SYMBOL_PRINT, YY_STACK_PRINT, YY_REDUCE_PRINT):
8106 (yyerrorlab): Use /*CONSTCOND*/ to suppress lint warnings.
8107
8108
8109 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.
8110 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
8111
8112 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
8113
8114 Undo the parts of the unlocked-I/O change that substituted
8115 putc or puts for printf. This might hurt performance a bit,
8116 but some people prefer the printf style.
8117 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
8118 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.
8119 All uses replaced by YYFPRINTF and YYDPRINTF.
8120 * data/yacc.c: Likewise.

8128 * src/output.c (escaped_output): Likewise.
8129 (user_actions_output): Break apart two printfs.
8130 * src/parse-gram.y (%printer): Prefer printf to putc and puts.
8131 * src/reduce.c (reduce_print): Likewise.
8132 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
8133 * src/system.h: Include unlocked-io.h rathe than stdio.h.
8134
8135 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
8136 Use assignments rather than casts-to-void to suppress
8137 unused-variable warnings. This pacifies 'lint'.
8138 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
8139 unused-variable warnings.
8140
8141 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
8142
8143 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
8144
8145 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
8146
8147 Use unlocked I/O for a minor performance improvement on hosts like
8148 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8149 is to use the gnlib unlocked-io module, and to prefer putc and
8150 puts to printf when either will work (since the latter doesn't
8151 come in an unlocked flavor).
8152 * bootstrap (gnulib_modules): Add unlocked-io.
8153 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
8154 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
8155 Prefer them to YYFPRINTF and YYDPRINTF if either will do,
8156 and similarly for puts and putc and printf.
8157 * data/yacc.c: Likewise.
8158 * lib/bitset.c (bitset_print): Likewise.
8159 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.
8160 * lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer putc and puts
8161 to printf.
8162 * lib/lbitset.c (debug_lbitset): Likewise.
8163 * src/closure.c (print_firsts, print_fderives): Likewise.
8164 * src/gram.c (grammar_dump): Likewise.
8165 * src/lalr.c (look_ahead_tokens_print): Likewise.
8166 * src/output.c (escaped_output): Likewise.
8167 (user_actions_output): Coalesce two printfs.
8168 * src/parse-gram.y (%printer): Prefer putc and puts to printf.
8169 * src/reduce.c (reduce_print): Likewise.
8170 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
8171 * src/system.h: Include unlocked-io.h rather than stdio.h.
8172
8173 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
8174 this confuses xgettext.
8175

8177
8178 * bootstrap (gnulib_modules): Add strverscmp.

8215
8216 2005-10-02 Juan Manuel Guerrero <juan.guerrero@gmx.de>
8217
8218 * lib/subpipe.c: New function end_of_output_subpipe() added
8219 to allow support for non-posix systems. This is a no-op function
8220 for posix systems.
8221
8222 * lib/subpipe.h: New function end_of_output_subpipe() added
8223 to allow support for non-posix systems. This is a no-op function
8224 for posix systems.
8225
8226 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
8227 handle the lack of pipe/fork functionality on non-posix systems.

8245 2005-10-02 Akim Demaille <akim@epita.fr>
8246
8247 * data/location.cc: New, extract from...
8248 * data/lalr1.cc: here.
8249 (location.hh): Include it after the user prologue, in case the
8250 filename type is defined by the user.
8251 Forward declation location and position before the pre-prologue.
8252 (yyresult_): Rename as...
8253 (yyresult): this, it's a local variable, not an attribute.
8254 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
8255
8256 2005-10-01 Akim Demaille <akim@epita.fr>

8265 (parser::token): New, from the moved free definition of tokens.
8266 (parser::semantic_value): Now a full definition instead of an
8267 indirection to YYSTYPE.

8291 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
8292 parser members, replaced by...
8293 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
8294 local variables.
8295 (yysyntax_error_): Takes the state number as argument.
8296 (yyreduce_print_): Use the argument yyrule, not the former
8297 attribute yyn_.
8298
8299 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
8300
8301 * bootstrap (gnulib_modules): Add verify.

8309
8310 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
8311 local variables whose names begin with 'yy'.
8312 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8313 Trivial changes from Joel E. Denny.
8314
8315 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
8316 it itself.
8317 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
8318 don't use alloca any more.
8319
8320 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
8321 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
8322 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
8323 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
8324 to match yacc.c, to test more hosts.
8325
8326 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
8327
8328 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
8329 doesn't affect behavior.
8330 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
8331 Solaris, AIX, MSC.
8332 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
8333 This works a bit better with glibc, if user code has already included
8334 stdlib.h.
8335 * doc/bison.texinfo (Bison Parser): Document that users can't
8336 arbitrarily use malloc and free for other purposes. Document
8337 that <alloca.h> and <malloc.h> might be included.
8338 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
8339 user must declare alloca.

8350 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
8351 (YYSTACK_ALLOC_MAXIMUM): Use it.
8352 (yysyntax_error): New function.
8353 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
8354 multiple syntax errors are reported, and alloca is being used.
8355 Instead, reallocate buffers twice as big each time, so that
8356 we waste at most half the allocated memory. Start with a small
8357 (128-byte) buffer that will suffice in most cases anyway.
8358 Use yysyntax_error to do most of the work.
8359
8360 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8361 yynerrs is the number of errors reported, not the number of
8362 errors encountered.
8363
8364 * tests/glr-regression.at (Duplicated user destructor for lookahead):
8365 Mark it as expected to fail.
8366 Cast result of malloc; problem reported by twlevo@xs4all.nl.
8367 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
8368 Don't start user-code symbols with "yy", to avoid name space problems.
8369
8370 2005-09-19 Akim Demaille <akim@epita.fr>
8371
8372 Remove the traits, failed experiment.
8373 It never proved useful, and anyway because of the current
8374 definition, it was not possible to have several specialization of
8375 this traits, making it useless.
8376 * data/lalr1.cc (yy:traits): Remove.
8377 Inline its definitions in the parser class.
8378
8379 2005-09-19 Akim Demaille <akim@epita.fr>

8401 * src/output.c (prepare): Likewise.
8402 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8403 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8404 is not defined. This is an awful hack, but it's enough for now.
8405 All callers changed.
8406 * tests/glr-regression-at (make_value): Args are const pointers now,
8407 to avoid GCC warning.
8408 (Duplicated user destructor for lookahead): New test. Currently
8409 skipped. It fails on my host but I'm not sure it'll always fail.
8410
8411 2005-09-16 Akim Demaille <akim@epita.fr>
8412
8413 * src/symtab.h (struct symbol): Declare the printer and destructor

8427 as default values.
8428
8429 2005-09-16 Akim Demaille <akim@epita.fr>
8430
8431 * data/lalr1.cc (yylex_): Remove, inline its code.
8432 (yyreport_syntax_error_): Remove, replaced by...
8433 (yysyntax_error_): this which returns a string and leaves to the
8434 caller the call to the users' error function.
8435 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8436 Move from members of the parser object...
8437 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
8438 to local variables of the parse function.
8439
8440 2005-09-16 Akim Demaille <akim@epita.fr>
8441
8442 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
8443 since it's in Bison's name space.

8446
8447 * data/glr.c (yyresolveValue): Add default case to pacify
8448 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.

8452 returns 2.
8453
8454 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
8455 (b4_filename_type): Renamed back from b4_file_name_type. All uses
8456 changed.
8457 (class position): file_name -> filename (reverting). All uses changed.
8458
8459 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
8460
8461 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8462 do anything if $@ exists. This reverts part of the 2005-07-07
8463 patch.
8464
8465 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8466
8467 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8468 contains obsolete information and isn't worth distributing as a
8469 separate file anyway.
8470 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
8471 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
8472 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
8473 (yyparse): Abort if user code uses longjmp to throw an unexpected
8474 value.
8475
8476 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
8477
8478 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
8479 Suggested by twlevo@xs4all.nl.
8480
8481 * data/glr.c (YYCHK1): Do not assume YYE is in range.
8482 This avoids a diagnostic from gcc -Wswitch-enum.
8483 Problem reported by twlevo@xs4all.nl.
8484
8485 * doc/bison.texinfo: Don't use "filename", as per GNU coding
8486 standards. Use "file name" or "file" or "name", depending on
8487 the context.
8488 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
8489 not to hack/foo.tab.c.
8490 (Calc++ Top Level): 2nd arg of main is not const.
8491 * data/glr.c: b4_filename -> b4_file_name.
8492 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
8493 All uses changed.
8494 (class position): filename -> file_name. All uses changed.
8495 * data/yacc.c: b4_filename -> b4_file_name.
8496 * lib/bitset.h: filename -> file_name in local vars.
8497 * lib/bitset_stats.c: Likewise.
8498 * src/files.c: Likewise.
8499 * src/scan-skel.l ("@output ".*\n): Likewise.
8500 * src/files.c (file_name_split): Renamed from filename_split.
8501 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
8502
8503 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
8504
8505 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
8506 to accommodate latest gnulib.
8507
8508 * tests/glr-regression.at (Duplicate representation of merged trees):
8509 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
8510
8511 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
8512 needed.
8513
8514 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
8515
8516 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
8517 All uses changed. Invoke user destructor after an error during a
8518 split parse (trivial change from Joel E. Denny).
8519
8520 * tests/glr-regression.at
8521 (User destructor after an error during a split parse): New test case.
8522 Problem reported by Joel E. Denny in:
8523 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
8524
8525 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
8526
8527 * README-cvs: Give URLs for recommended tools.
8528 Mention Gzip version problem, and bootstrapping issues.
8529 Remove troubleshooting section, as it's somewhat obsolete.
8530
8531 * bootstrap (no_cache): New var, to accommodate different wget
8532 variants. Use it instead of '-C off'. Problem reported by
8533 twlevo@xs4all.nl.
8534
8535 * data/glr.c (yydestroyStackItem): New function.
8536 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
8537 debugging information. Problem reported by Joel E. Denny.
8538
8539 2005-08-25 Akim Demaille <akim@epita.fr>
8540
8541 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
8542
8543 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
8544
8545 * data/glr.c (yyrecoverSyntaxError, yyreturn):
8546 Don't invoke destructor on unresolved entries.
8547 * tests/glr-regression.at
8548 (User destructor for unresolved GLR semantic value): New test case.
8549 Problem reported by Joel E. Denny in:
8550 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
8551
8552 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
8553
8554 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
8555 Add strnlen.c.
8556 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
8557 lib-prefix.m4, po.m4.
8558
8559 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
8560 in yydestruct diagnostic, since it might not be an error.
8561 Problem reported by Joel Denny near end of
8562 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
8563 * data/lalr1.cc (yyerturn): Likewise.
8564 * data/yacc.c (yyreturn): Likewise.
8565 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
8566
8567 * src/files.c: Remove obsolete FIXME comment.
8568
8569 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
8570 with the other templates, and to fix bogus run-on messages such
8571 as the one reported at the end of
8572 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
8573 All callers changed to avoid the newline.
8574 (yyprocessOneStack): Output two lines rather than one, to accommodate
8575 the above change. This changes the debug output format slightly.
8576
8577 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
8578 reported by Joel E. Denny in
8579 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
8580 (trivial change).
8581 * tests/glr-regression.at (Duplicate representation of merged trees):
8582 New test, from Joel E. Denny in:
8583 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
8584 * THANKS: Add Joel E. Denny.
8585
8586 * configure.ac (AC_INIT): Bump to 2.0c.
8587
8588 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
8589
8590 * NEWS: Version 2.0b.
8591
8592 * Makefile.am (SUBDIRS): Put examples before tests, so that
8593 "make check" doesn't finish with "All 1 tests passed".
8594
8595 * tests/regression.at (Token definitions): Don't rely on
8596 AT_PARSER_CHECK for data that contains backslashes. It currently
8597 uses 'echo', and 'echo' isn't portable if its argument contains
8598 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
8599 that the byte '\0xff' is not printable in the C locale; it is,
8600 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
8601 not printable, so use '\0x81' to test.
8602
8603 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
8604 version of GCC, since the macro is used with non-GCC compilers.
8605
8606 Fix core dump reported by Pablo De Napoli in
8607 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
8608 * tests/regression.at (Invalid inputs with {}): New test.
8609 * src/parse-gram.y (token_name): Translate type before using
8610 it as an index.
8611
8612 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
8613 the user's name space. All uses changed to __attribute__
8614 ((__unused__)).
8615 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
8616 Add __attribute__ ((__noreturn__)).
8617
8618 * etc/clcommit: Remove. We weren't using it, and it failed
8619 "make maintainer-distcheck".
8620 * Makefile.maint: Merge from coreutils.
8621 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
8622 (syntax-check-rules): Change list of rules as described below.
8623 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
8624 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
8625 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
8626 (sc_trailing_space): New rules.
8627 (sc_xalloc_h_in_src): Remove.
8628 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
8629 (sc_space_tab, sc_error_exit_success, sc_changelog):
8630 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
8631 (makefile-check, po-check, author_mark_check):
8632 (makefile_path_separator_check, copyright-check):
8633 Use grep -n, to make it easier to find violations.
8634 Use CVS_LIST and CVS_LIST_EXCEPT.
8635 (header_regexp, h_re): Remove.
8636 (dd_c): New macro.
8637 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
8638 (my-distcheck): Use more-modern GCC flags.
8639 (signatures, %.asc): Remove.
8640 (rel-files, announcement): Remove signatures.
8641 Restore old updating code, even though we don't use it, so
8642 that we're the same as coreutils.
8643 (alpha, beta, major): Depend on news-date-check.
8644 Make the upload commands.
8645
8646 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
8647 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
8648 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
8649 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
8650 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
8651 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
8652 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
8653 * tests/sets.at: Likewise.
8654
8655 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
8656 we comment out the Autoconf version number.
8657 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
8658 it's error-prone and "make maintainer-distcheck" rejects it.
8659
8660 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
8661 Indent calls to "error" to pacify "make maintainer-distcheck",
8662 when the calls are not intended to be translated.
8663 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
8664
8665 * src/Makefile.am (DEFS): Use +=, to pacify
8666 "make maintainer-distcheck".
8667 (bison_SOURCES): Add scan-skel.h.
8668 (sc_tight_scope): New rule, from coreutils.
8669
8670 * src/files.c (src_extension, header_extension):
8671 Now static, not extern.
8672 * src/getargs.c (short_options): Likewise.
8673 * src/muscle_tab.c (muscle_table): Likewise.
8674 * src/parse-gram.y (current_class, current_type, current_prec):
8675 Likewise.
8676 * src/reader.c (grammar_end, previous_rule_end): Likewise.
8677 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
8678 * src/main.c (main): Cast bindtextdomain and textdomain calls to
8679 void, to avoid warning when NLS is disabled.
8680 * src/output.c: Include scan-skel.h.
8681 (scan_skel): Remove decl, since scan-skel.h does this.
8682 (output_skeleton):
8683 Indent calls to "error" to pacify "make maintainer-distcheck".
8684 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
8685 * src/reader.h (gram_end, gram_lineno): New decls to pacify
8686 "make maintainer-distcheck".
8687 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
8688 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
8689 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
8690 (skel_lex_destroy, scan_skel): Move these decls to...
8691 * src/scan-skel.h: New file.
8692 * src/uniqstr.c (uniqstr_assert):
8693 Indent calls to "error" to pacify "make maintainer-distcheck".
8694
8695 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
8696 not @VAR@.
8697
8698 * tests/torture.at: Revamp to avoid misuse of atoi that
8699 "make maintainer-distcheck" complained about.
8700
8701 * examples/extexi (message): Don't print a message more than once,
8702 and omit line-number decoration that makes Emacs compile think
8703 that informative messages are worth worrying about.
8704
8705 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
8706
8707 * configure.ac: Update version number.
8708
8709 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
8710 accidentally.
8711 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
8712 autogenerated by the maintainer.
8713 * examples/calc++/.cvsignore: Add *.yy.
8714
8715 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
8716 * lib/bitset_stats.c (bitset_stats_init): Likewise.
8717 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8718
8719 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
8720
8721 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
8722 from maintainer-distcheck about casting the argument of 'free'.
8723
8724 * NEWS: Mention recent yytname changes.
8725 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
8726
8727 * bootstrap: For translations that have not yet been upgraded to
8728 the new runtime-po domain, prime the pump by extracting the
8729 relevant strings from the obsolete translations. This code can be
8730 removed once the bison-runtime domain has been translated by each
8731 team.
8732
8733 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
8734 now that token names are already quoted.
8735
8736 Fix problem reported by Anthony Heading.
8737 * data/glr.c (YYTOKEN_TABLE): New macro.
8738 (yytname): Define if YYTOKEN_TABLE.
8739 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
8740 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
8741 (YYERROR_VERBOSE): Define the same way the other skeletons do.
8742 * src/output.c (prepare_symbols): Output token_table_flag.
8743
8744 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
8745
8746 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
8747 again if the first call fails.
8748
8749 * data/glr.c (yytnamerr): New function.
8750 (yyreportSyntaxError): Use it to dequote most string literals.
8751 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
8752 with other skeletons. All uses changed.
8753 (yytnameerr_): New function.
8754 (yyreport_syntax_error): Use it to dequote most string literals.
8755 * data/yacc.c (yytnamerr): New function.
8756 (yyerrlab): Use it to decode most string literals.
8757 * doc/bison.texinfo (Decl Summary, Calling Convention):
8758 Clarify quoting convention of yytname.
8759 * src/output.c (prepare_symbols): Quote all names. This undoes
8760 the 2005-04-17 change, which is now accomplished (mostly) via
8761 changes in the parsers as described above.
8762 * tests/regression.at (Token definitions, Web2c Actions):
8763 Undo most 2005-04-17 change here, too.
8764
8765 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
8766
8767 Fix more problems reported by twlevo@xs4all.nl.
8768 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8769 remove trailing spaces. This loses the exit status of ./types,
8770 and isn't needed since ./types shouldn't be emitting trailing
8771 spaces.
8772 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8773 as the stack isn't valid in that case.
8774
8775 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8776 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8777 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8778 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
8779 is used.
8780 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
8781 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
8782 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
8783 Likewise.
8784
8785 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
8786 overly-picky compilers that reject 'char *foo = "bar";'.
8787
8788 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8789 to FILE * parameter, not to stderr. This fixes a typo introduced
8790 in the 2005-07-12 change.
8791
8792 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
8793 warnings from GCC 4.
8794
8795 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
8796 (yyglrShiftDefer, yysplitStack):
8797 Remove unused parameters b4_pure_formals. All uses changed.
8798 (yyglrShift): Remove unused parameters b4_user_formals.
8799 All uses changed.
8800 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
8801
8802 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
8803
8804 Destructor cleanups and regularization among the three skeletons.
8805 * NEWS: Document the behavior changes.
8806 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8807 stack before failing, as the cleanup code will do it for us now.
8808 * data/lalr1.cc (yyerrlab): Likewise.
8809 * data/glr.c (yyparse): Pop everything off the stack before
8810 freeing it, so that destructors get called properly.
8811 * data/lalr1.cc (yyreturn): Likewise.
8812 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8813 This is more consistent.
8814 * doc/bison.texinfo (Destructor Decl): Mention more reasons
8815 why destructors might be called. 1.875 -> 2.1.
8816 (Destructor Decl, Decl Summary, Table of Symbols):
8817 Some English-language cleanups for %destructor.
8818 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8819 Add output line for destructor of start symbol.
8820 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
8821 because of that same extra output line.
8822
8823 * NEWS: Document minor wording changes in diagnostics of
8824 Bison-generated parsers.
8825 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
8826 Remove unused formals. All uses changed.
8827 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
8828 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
8829 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
8830 Rename yyoverflowab to yyexhaustedlab.
8831 When memory exhaustion occurs during syntax-error reporting,
8832 report it separately rather than in a single diagnostic; this
8833 eases translation.
8834 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
8835 (Memory Exhausted): Renamed from Parser Stack Overflow.
8836 Revamp wording slightly to prefer "memory exhaustion".
8837 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
8838
8839 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
8840
8841 Add i18n support to the GLR skeleton. Partially fix the C++
8842 skeleton; a C++ expert needs to finish this. Remove debugging
8843 msgids; there's little point to having them translated, since they
8844 can be understood only by someone who can read the
8845 (English-language) source code.
8846
8847 Generate runtime-po/bison-runtime.pot automatically, so that we
8848 don't have to worry about garbage getting in that file. We'll
8849 make sure after the next official release that old msgids don't
8850 get lost. See
8851 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
8852
8853 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
8854 Now auto-generated.
8855 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8856 Fix typos in explanations of the runtime file.
8857 * bootstrap: Change gettext keyword from YYI18N to YY_.
8858 Use standard Makefile.in.in in runtime-po, since we'll arrange
8859 for backward-compatible bison-runtime.po files in a different way.
8860 * data/glr.c (YY_): New macro, from yacc.c.
8861 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8862 Translate messages intended for users.
8863 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8864 the wording in the other skeletons. We don't know that the memory
8865 is virtual.
8866 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8867 Use same method that yacc.c uses.
8868 Don't translate debugging messages.
8869 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8870 it doesn't work (yet), and requires C++ expertise to fix.
8871 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8872 Move defn to a more logical place, to be consistent with other
8873 skeletons.
8874 Don't translate debugging messages.
8875 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8876 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8877 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8878 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
8879
8880 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
8881 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
8882 void, not int.
8883 * tests/glr-regression.at (Badly Collapsed GLR States):
8884 Likewise.
8885 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8886 yylex should return 0 at EOF rather than aborting.
8887
8888 Improve tests for stack overflow in GLR parser.
8889 Problem reported by twlevo@xs4all.nl.
8890 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
8891 All uses removed.
8892 (yyStackOverflow): Just longjmp, but with value 2 so that caller
8893 can handle the problem.
8894 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8895 (yyparse): New local variable yyresult to record the result.
8896 Use result of setjmp to set it, rather than storing itinto
8897 struct.
8898 (yyDone): Remove label.
8899 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
8900 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
8901 if YYABORT is used).
8902 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
8903 yyparse status; put status > 1 into diagnostic.
8904 Check that status==2 works.
8905 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
8906 Use exit status 3 for failure to open (which shouldn't happen).
8907
8908 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
8909
8910 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
8911 1 on syntax error; just let yyparse do its thing.
8912 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
8913 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
8914 (Exploding the Stack Size with Alloca):
8915 (Exploding the Stack Size with Malloc):
8916 Expect exit status 2, not 1, since the parser is supposed to blow
8917 its stack. Problem reported by twlevo@xs4all.nl.
8918
8919 * data/glr.c (yyparse): Don't assume that the initial calls
8920 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
8921 Print a stack-overflow message and fail instead.
8922 Initialize the line-number information before creating the stack,
8923 so that the stack-overflow message can report line zero safely.
8924
8925 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
8926
8927 Fix problems reported by twlevo@xs4all.nl.
8928 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
8929 (yyuserMerge): Provide a default case if b4_mergers is empty.
8930 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
8931 * tests/glr-regression.at
8932 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8933 Add casts to pacify C++ compilers.
8934 * tests/glr-regression.at (Improper merging of GLR delayed action
8935 sets): Declare yylex before using it.
8936 * tests/Makefile.am (maintainer-check-g++): Fix a stray
8937 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
8938 test for valgrind; valgrind is independent of g++.
8939 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
8940 for compatibility with POSIX 1003.1-2001 (if running coreutils).
8941 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
8942 Use a destructor, so that we can expand the stack. Change
8943 YYSTYPE to char * so that we can free it. Cast result of malloc.
8944
8945 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8946
8947 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
8948 a valgrind failure. Problem reported by twlevo@xs4all.nl.
8949
8950 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
8951
8952 * PACKAGING: New file, suggested by Bruno Haible and taken from
8953 similar wording in gettext's PACKAGING file.
8954 * NEWS: Mention PACKAGING.
8955 * Makefile.am (EXTRA_DIST): Add PACKAGING.
8956
8957 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
8958
8959 * NEWS: Document recent i18n improvements.
8960 * bootstrap: Get runtime translations into runtime-po.
8961 Create runtime-po files automatically, if possible.
8962 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
8963 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
8964 does not infringe on the user's name space.
8965 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
8966 * doc/bison.texinfo (Internationalization): Revamp the English
8967 and Texinfo syntax a bit, to try to make it clearer.
8968 (Bison Options, Option Cross Key): Mention --print-localedir.
8969 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
8970 YYENABLE_NLS. Quote a bit more.
8971 * runtime-po/.cvsignore: New file.
8972 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
8973 * runtime-po/Rules-quot: Remove; now created by bootstrap.
8974 * runtime-po/quot.sed: Likewise.
8975 * runtime-po/boldquot.sed: Likewise.
8976 * runtime-po/en@quot.header: Likewise.
8977 * runtime-po/en@boldquot.header: Likewise.
8978 * runtime-po/insert-header.sin: Likewise.
8979 * runtime-po/remove-potcdate.sin: Likewise.
8980 * runtime-po/Makevars: Likewise.
8981 * runtime-po/LINGUAS: Likewise.
8982 * runtime-po/de.po: Likewise; we will rely on the translation project
8983 to maintain this, so "bootstrap" should get it.
8984 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
8985 its value.
8986 * src/main.c (main): Bind the bison-runtime domain, too.
8987
8988 2005-07-12 Bruno Haible <bruno@clisp.org>
8989
8990 * data/yacc.c: Include <libintl.h> when NLS is enabled.
8991 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
8992 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
8993 * runtime-po: New directory.
8994 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
8995 $(DOMAIN).pot-update rule, so that old messages are never dropped.
8996 * runtime-po/Rules-quot: New file, copied from po/.
8997 * runtime-po/quot.sed: Likewise.
8998 * runtime-po/boldquot.sed: Likewise.
8999 * runtime-po/en@quot.header: Likewise.
9000 * runtime-po/en@boldquot.header: Likewise.
9001 * runtime-po/insert-header.sin: Likewise.
9002 * runtime-po/remove-potcdate.sin: Likewise.
9003 * runtime-po/Makevars: New file.
9004 * runtime-po/POTFILES.in: New file.
9005 * runtime-po/LINGUAS: New file.
9006 * runtime-po/bison-runtime.pot: New file.
9007 * runtime-po/de.po: New file.
9008 * m4/bison.m4: New file.
9009 * Makefile.am (SUBDIRS): Add runtime-po.
9010 (aclocaldir, aclocal_DATA): New variables.
9011 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
9012 Define aclocaldir.
9013 * src/getargs.c (usage): Document --print-localedir option.
9014 (PRINT_LOCALEDIR_OPTION): New enum item.
9015 (long_options): Add --print-localedir option.
9016 (getargs): Handle --print-localedir option.
9017 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
9018 (Internationalization): New section.
9019
9020 2005-07-12 Akim Demaille <akim@epita.fr>
9021
9022 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
9023 for consistency with the rest of the code.
9024 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
9025 Add separators.
9026
9027 2005-07-12 Akim Demaille <akim@epita.fr>
9028
9029 * src/parse-gram.y: Use %printer instead of YYPRINT.
9030
9031 2005-07-12 Akim Demaille <akim@epita.fr>
9032
9033 * src/symtab.h, src/symtab.c (symbol_print): New.
9034 * src/symlist.h, src/symlist.c (symbol_list_print): New.
9035 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
9036
9037 2005-07-12 Akim Demaille <akim@epita.fr>
9038
9039 * data/glr.c (b4_syncline): Fix (swap) the definitions of
9040 b4_at_dollar and b4_dollar_dollar.
9041
9042 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
9043
9044 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
9045 and Pennello's paper.
9046
9047 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
9048
9049 * data/yacc.c (yyparse): Undo previous patch. Instead,
9050 set yylsp[0] and yyvsp[0] only if the initial action
9051 sets yylloc and yylval, respectively.
9052
9053 * data/yacc.c (yyparse): In the initial action, set
9054 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
9055 This avoids the use of undefined variables if the initial
9056 action does not set yylloc and/or yylval.
9057
9058 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
9059
9060 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
9061 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
9062 Remove from CVS. These files are automatically generated.
9063 * examples/extexi: Clarify that this file is now part of Bison,
9064 not GNU M4, and that it works with any POSIX-compatible Awk.
9065 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
9066 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
9067 so that we also get calc++-parser.yy. Geneate it.
9068 Use $(AWK), not gawk, since any conforming Awk will do.
9069 Put comment before action, since older 'make' can't handle comment
9070 in action.
9071 $(BUILT_SOURCES): List all built sources, not just some of them.
9072 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
9073 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
9074 $($(calc_sources_generated)): Remove unnecessary test for existence
9075 of target. (This had a shell syntax error anyway; a stray "x".)
9076 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
9077 calc++-parser.yy.
9078 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
9079
9080 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
9081 implied by the other modules.
9082
9083 2005-07-06 Akim Demaille <akim@epita.fr>
9084
9085 Bind examples/calc++ to the package.
9086 * examples/calc++/Makefile: Remove, replaced by...
9087 * examples/calc++/Makefile.am: ... this new file.
9088 * examples/calc++/test: Remove input.
9089 * examples/calc++/compile: Remove.
9090 * examples/Makefile.am: New.
9091 * configure.ac, Makefile.am: Adjust.
9092 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
9093
9094 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
9095
9096 * data/glr.c (yyFail): Drastically simplify; since the format argument
9097 never had any % directives, we can simply pass it to yyerror.
9098 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
9099 be modified later, as that is the usual style in glr.c.
9100 Problems reported by Paul Hilfinger.
9101
9102 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
9103 and size overflow errors.
9104 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
9105 in case the user prolog sets feature-test macros like _GNU_SOURCE.
9106 (YYSIZEMAX): New macro.
9107 (yystpcpy): New function, taken from yacc.c.
9108 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9109 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9110 so that we don't have to maintain their signatures.
9111 (yyFail): Check for buffer overflow, by using vsnprintf rather
9112 than vsprintf. Allocate a bigger buffer if possible.
9113 Report an error if buffer allocation fails.
9114 (yyStackOverflow): New function.
9115 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9116 the initialization was successful. It might fail if storage was
9117 exhausted.
9118 (yyexpandGLRStack): Add more checks for storage allocation failure.
9119 Use yyStackOverflow to report failures.
9120 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
9121 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
9122 Don't assume stack number fits in int.
9123 (yysplitStack): Check for storage allocation failure.
9124 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
9125 can print diagnostics on storage allocation failure. All callers
9126 changed.
9127 (yyresolveValue): Use yybool for boolean.
9128 (yyreportSyntaxError): Check for size-calculation overflow.
9129 This code is taken from yacc.c.
9130 (yyparse): Check for storage allocation errors when allocating
9131 the initial stack.
9132
9133 2005-07-05 Akim Demaille <akim@epita.fr>
9134
9135 Extract calc++ from the documentation.
9136 * doc/bison.texinfo (Calc++): Add the extraction marks.
9137 * examples/extexi: New, from the aborted GNU Programming 2E.
9138 Separate the different paragraph of a file with empty lines.
9139 * examples/Makefile: Use it to extract the whole calc++ example.
9140
9141 2005-06-24 Akim Demaille <akim@epita.fr>
9142
9143 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
9144 class typedefs.
9145
9146 2005-06-22 Akim Demaille <akim@epita.fr>
9147
9148 * doc/bison.texinfo (C++ Language Interface): First stab.
9149 (C++ Parsers): Remove.
9150
9151 2005-06-22 Akim Demaille <akim@epita.fr>
9152
9153 * data/lalr1.cc (yylex_): Honor %lex-param.
9154
9155 2005-06-22 Akim Demaille <akim@epita.fr>
9156
9157 Start a set of simple examples.
9158 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
9159 * examples/calc++/calc++-driver.hh,
9160 * examples/calc++/calc++-parser.yy,
9161 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
9162 * examples/calc++/compile, examples/calc++/test: New.
9163
9164 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
9165
9166 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
9167 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
9168 which stems from the 2005-05-27 patch.
9169
9170 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9171
9172 * data/glr.c: Modify treatment of unused parameters to permit use
9173 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
9174
9175 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
9176
9177 Fix infringement on user name space reported by Janos Zoltan Szabo.
9178 * data/yacc.c (yyparse): strlen -> yystrlen.
9179
9180 2005-05-30 Akim Demaille <akim@epita.fr>
9181
9182 * data/lalr1.cc (_): New.
9183 Translate the various messages.
9184
9185 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
9186
9187 Fix infringement on user name space reported by Bruno Haible.
9188 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9189 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9190 the user's name space.
9191 (alloca): Include <stdlib.h> to get it, if it's not built in.
9192 (YYMALLOC, YYFREE): Define only if needed.
9193 (malloc, free): Declare, but only if needed, as this infringes on
9194 the user name space.
9195
9196 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
9197
9198 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
9199 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
9200 with %d format.
9201 * lib/ebitset.c (min, max): Undef before defining.
9202 * lib/vbitset.c (min, max): Likewise.
9203 * lib/subpipe.c (create_subpipe): Save local variables in case
9204 vfork clobbers them.
9205
9206 2005-05-24 Bruno Haible <bruno@clisp.org>
9207
9208 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
9209 error message syntax used by gcc-4.0.
9210
9211 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
9212
9213 * README: Mention m4 1.4.3. Remove obsolete advice about
9214 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
9215
9216 * bootstrap: Remove workaround for problem I encountered with
9217 gettext 0.14.1; it seems to be fixed now.
9218
9219 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
9220
9221 * NEWS: Version 2.0a.
9222
9223 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
9224 the previous change.
9225
9226 Various maintainer cleanups.
9227 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9228 conftest*, for benefit of CVS commands run at the same time as
9229 "configure". Add build-aux, since "bootstrap" now creates it and
9230 its subfiles.
9231 * Makefile.cfg (move_if_change): Remove.
9232 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9233 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
9234 (po_repo, do-po-update, po-update, wget_files, get-targets):
9235 (config.guess-url_prefix, config.sub-url_prefix):
9236 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
9237 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
9238 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
9239 Remove.
9240 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
9241 this is now the recommended name.
9242 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
9243 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9244 ylwrap. These files now go into build-aux.
9245 * config/move-if-change: Remove.
9246 * config/prev-version.txt: Bump from 1.75 to 2.0.
9247
9248 * bootstrap: Add stdio-safer, unistd-safer modules.
9249 Remove m4/glibc2.m4 (introduced by latest gnulib, but
9250 we don't need it).
9251 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
9252 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9253 * lib/subpipe.c: Include "unistd-safer.h".
9254 (create_subpipe): Make sure all the newly-created
9255 file descriptors are > 2, so that diagnostics don't
9256 get sent down them (which might cause Bison to hang, in theory).
9257 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
9258 * src/files.c (xfopen): Use fopen_safer, not fopen.
9259
9260 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
9261 yesterday's yacc.c fix.
9262
9263 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
9264
9265 * data/glr.c, data/lalr1.cc: Update copyright date.

9267 Fix a destructor bug reported by Wolfgang Spraul in
9268 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
9269 * data/yacc.c (yyabortlab): Don't call destructor, and
9270 don't set yychar to EMPTY.
9271 (yyoverflowlab): Don't call destructor.
9272 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
9273 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
9274 since we no longer output the message "discarding lookahead token
9275 end of input ()".
9276
9277 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9278
9279 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
9280 fix a small glitch in debugging output.
9281 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
9282 after YY_SYMBOL_PRINT where needed.
9283
9284 (struct yyGLRState): Add some comments.
9285 (struct yySemanticOption): Add some comments.
9286 (union yyGLRStackItem): Add comment.
9287
9288 (yymergeOptionSets): Correct this to properly perform the union,
9289 avoiding infinite reported by Michael Rosien.
9290 Update comment.
9291
9292 * tests/glr-regression.at: Add test for GLR merging error reported
9293 by M. Rosien.

9333 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
9334
9335 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
9336 Problem reported by Ralf Menzel.
9337
9338 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9339
9340 * tests/actions.at: Test that stack overflow invokes destructors.
9341 From Marcus Holland-Moritz.
9342 * data/yacc.c (yyerrlab): Move the code that destroys the stack
9343 from here....
9344 (yyreturn): to here. That way, destructors are called properly
9345 even if the stack overflows, or the user calls YYACCEPT or
9346 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
9347 (yyoverflowlab): Destroy the lookahead.
9348
9349 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
9350
9351 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
9352
9353 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
9354
9355 * NEWS: Bison-generated C parsers no longer quote literal strings
9356 associated with tokens.
9357 * src/output.c (prepare_symbols): Don't escape strings,
9358 since users don't want to see C escapes.
9359 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9360 in diagnostics.
9361 * tests/input.at (Torturing the Scanner): Likewise.
9362 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9363
9364 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9365
9366 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9367 the data size is known to be too small and we can't increase it.
9368 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9369
9370 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9371
9372 * src/parse-gram.y: Include quotearg.h.
9373 (string_as_id): Quote $1 before using it as a key, since the
9374 lexer no longer quotes it for us.
9375 (string_content): Don't strip quotes, since lexer no longer
9376 quotes it for us.
9377 * src/scan-gram.l: Include quotearg.h.
9378 ("\""): Omit quote.
9379 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9380 a key, since the rest of the lexer doesn't quote it.
9381 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9382 * tests/regression.at (Token definitions): Check for backslashes
9383 in token strings.
9384
9385 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9386 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9387 (yyparse): Revamp code to generate long syntax error message, to
9388 make it easier to translate, and to avoid problems with arithmetic
9389 overflow. Change "virtual memory" to "memory" in diagnostic, since
9390 we don't know whether the memory is virtual.
9391
9392 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9393
9394 * NEWS: Bison-generated C parsers now use the _ macro to
9395 translate strings.
9396 * data/yacc.c (_) [!defined _]: New macro.
9397 All English strings wrapped inside this macro.
9398 * doc/bison.texinfo (Bison Parser): Document _.
9399 * po/POTFILES.in: Include src/parse-gram.c, since it now
9400 includes translateable strings that parse-gram.y doesn't.
9401
9402 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9403
9404 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9405 reverting the 2004-10-11 change to this function.
9406 (symbol_check_alias_consistency): Don't call symbol_type_set
9407 if the type name is already correct.
9408 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9409
9410 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9411
9412 * tests/regression.at (Token definitions): Don't use a token named
9413 c, as that generates a "#define c ..." that runs afoul of buggy
9414 stdlib.h that uses the identifier c as a member of struct
9415 drand48_data. Problem reported by Horst Wente.
9416
9417 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9418
9419 * bootstrap: Change translation URL from
9420 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
9421 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
9422 redirection glitches. Problem reported by twlevo@xs4all.nl.
9423
9424 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9425
9426 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9427 after operands; POSIX says this isn't portable for the c99 command.
9428
9429 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9430
9431 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9432 immediately if a data overrun has occurred; this may help us track
9433 down what may be a spurious failure on MacOS.
9434
9435 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9436
9437 Respond to problems reported by twlevo@xs4all.nl.
9438
9439 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9440
9441 * src/vcg.h: Comment fix.
9442 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9443 (G_CMAX): Change to -1 instead of INT_MAX.
9444
9445 * data/yacc.c (yyparse): Omit spaces before #line.
9446
9447 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9448
9449 * src/tables.c (state_number_to_vector_number): Put it inside an
9450 "#if 0", since it's not currently used. Problem reported by
9451 Roland McGrath.
9452
9453 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9454
9455 * src/output.c (escaped_output): Renamed from
9456 escaped_file_name_output, since we now use it for symbol tags as
9457 well. All uses changed.
9458 (symbol_destructors_output, symbol_printers_output):
9459 Escape symbol tags too.
9460 Problem reported by Matyas Forstner in
9461 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9462
9463 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9464 not needed.
9465 * src/output.c (user_actions_output, token_definitions_output,
9466 symbol_destructors_output, symbol_printers_output): Likewise.
9467 * src/reader.c (prologue_augment): Likewise.
9468 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
9469
9470 * src/vcg.c (output_edge): Don't quote linestyle arg.
9471 Problem reported by twlevo@xs4all.nl.
9472
9473 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
9474
9475 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
9476 example, reported by Derek M Jones. Also, make the example even
9477 more outrageous, to better illustrate how bad the problem is.
9478
9479 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
9480
9481 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
9482 putsym. Typo reported by Sebastian Piping.
9483
9484 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9485
9486 * doc/bison.texinfo (Language and Grammar): some -> same
9487 (Epilogue): int he -> in the
9488 Typos reported by Sebastian Piping via Justin Pence.
9489
9490 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9491
9492 * tests/glr-regression.at (Improper handling of embedded actions
9493 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
9494 embedded actions and $-N in GLR parsers", work around an Autoconf bug
9495 with dollar signs in test names.
9496 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
9497 for a similar reason.
9498
9499 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9500
9501 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
9502 wants to redefine G_VIEW.
9503
9504 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
9505
9506 * src/vcg.c (get_view_str): Remove case for normal_view.
9507 Problem reported by twlevo@xs4all.nl.
9508
9509 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
9510
9511 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
9512 Problem reported by twlevo@xs4all.nl.
9513
9514 * doc/bison.texinfo: Change @dircategory from "GNU programming
9515 tools" to "Software development". Requested by Richard Stallman
9516 via Karl Berry.
9517
9518 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
9519
9520 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
9521 Problem reported by twlevo@xs4all.nl.
9522
9523 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9524
9525 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
9526 keyword; it's not needed with modern compilers, and it doesn't
9527 affect correctness with older compilers. Suggested by
9528 twlevo@xs4all.nl.
9529
9530 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
9531
9532 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
9533 gcc -Wswitch-default.
9534 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9535 * data/yacc.c (yyparse): Likewise.
9536
9537 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
9538
9539 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
9540 already. Let config.h define any nonstandard values.
9541
9542 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
9543
9544 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
9545 for the benefit of slower hosts. Problem reported by
9546 Nelson H. F. Beebe.
9547
9548 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
9549
9550 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
9551 being defined and not used.
9552 * data/lalr1.cc (yyparse): Likewise.
9553 Use "if (false)" rather than "if (0)".
9554
9555 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
9556
9557 * TODO: Mention that we should allow NUL bytes in tokens.
9558
9559 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
9560
9561 * src/scan-skel.l (<<EOF>>): Don't close standard output.
9562 Problem reported by Hans Aberg.
9563
9564 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
9565
9566 * src/getargs.c (version): Happy new year; update overall
9567 program copyright date from 2004 to 2005.
9568
9569 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
9570 Problem reported by Hans Aberg.
9571 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
9572 (Output file names.): Add a test for the case when standard output
9573 is closed.
9574
9575 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
9576
9577 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
9578 to fix an oversight in the Bison 2.0 manual.
9579
9580 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
9581
9582 * NEWS: Version 2.0. Reformat the existing news items since
9583 1.875, so that related items are grouped together.
9584 * configure.ac (AC_INIT): Bump version to 2.0.
9585 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
9586
9587 * tests/torture.at (Exploding the Stack Size with Alloca): Set
9588 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
9589 otherwise, we're not testing alloca. Unfortunately there's no
9590 simple way to consult HAVE_ALLOCA here.
9591
9592 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
9593 for yymsg, too.
9594
9595 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
9596 hand. This avoids a warning about comparing int to size_t when
9597 GCC warnings are enabled.
9598
9599 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
9600
9601 * NEWS: Bison-generated parsers no longer default to using the
9602 alloca function (when available) to extend the parser stack, due
9603 to widespread problems in unchecked stack-overflow detection.
9604 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
9605 responsibility to set it to a positive value. This lets the user
9606 specify a value that is not a preprocessor constant.
9607 * data/yacc.c (YYMAXDEPTH): Likewise.
9608 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
9609 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
9610 to be a compile-time constant. However, explain the constraints on it.
9611 Also, explain the constraints on YYINITDEPTH.
9612 (Table of Symbols): Explain that alloca is no longer the default.
9613 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
9614 to 1.
9615
9616 * doc/bison.texinfo (Location Default Action): Mention that n must
9617 be zero when k is zero. Suggested by Frank Heckenbach.
9618
9619 2004-12-22 Akim Demaille <akim@epita.fr>
9620
9621 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
9622 (parser::state_type, parser::semantic_type, parser::location_type):
9623 Private, not public.
9624 (parser::parse): Return ints, not bool.
9625 Returning a bool introduces a problem: 0 corresponds to false, and
9626 it seems weird to return false on success. Returning true changes
9627 the conventions for yyparse.
9628 Alternatively we could return void and send an exception.
9629 There is no clear consensus (yet?).
9630 (state_stack, semantic_stack, location_stack): Rename as...
9631 (state_stack_type, semantic_stack_type, location_stack_type): these.
9632 Private, not public.
9633 * tests/c++.at: New.
9634 * tests/testsuite.at, tests/Makefile.am: Adjust.
9635
9636 2004-12-21 Akim Demaille <akim@epita.fr>
9637
9638 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
9639
9640 2004-12-21 Akim Demaille <akim@epita.fr>
9641
9642 Don't impose std::string for filenames.
9643
9644 * data/lalr1.cc (b4_filename_type): New.
9645 (position::filename): Use it.
9646 (parser.hh): Move the inclusion of stack.hh and location.hh below
9647 the user code, so that needed headers for the filename type can be
9648 included first.
9649 Forward declare them before the user code.
9650 * tests/Makefile.am (check-local, installcheck-local): Pass
9651 TESTSUITEFLAGS to the TESTSUITE.
9652
9653 2004-12-20 Akim Demaille <akim@epita.fr>
9654
9655 Use more STL like names: my_class instead of MyClass.
9656
9657 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
9658 (SemanticStack, SemanticType, StateStack, StateType)
9659 (TokenNumberType, Stack, Slice, Traits, Parser::location)
9660 (Parser::value): Rename as...
9661 (location_stack, location_type, rhs_number_type, semantic_stack)
9662 (semantic_type, state_stack, state_type, token_number_type, stack)
9663 (slice, traits, parser::yylloc, parser::yylval): these.
9664
9665 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
9666
9667 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
9668
9669 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
9670 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
9671
9672 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
9673
9674 Remove uses of 'short int' and 'unsigned short int'. This raises
9675 some arbitrary limits. It uses more memory but nowadays that's
9676 not much of an issue.
9677
9678 This change does not affect the generated parsers; that's a different
9679 task, as some users will want to conserve memory there.
9680
9681 Ideally we should use size_t to represent all object counts, and
9682 something like ptrdiff_t to represent signed differences of object
9683 counts; but that will require more code-cleanup than I have the
9684 time to do right now.
9685
9686 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
9687 Use size_t, not int or short int, to count objects.
9688 * src/closure.c (nritemset, closure): Likewise.
9689 * src/closure.h (nritemset, closure): Likewise.

9697 * src/gram.h (rule_number, rule): Use int, not short int.
9698 * src/output.c (prepare_rules): Likewise.
9699 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
9700 errs, reductions): Likewise.
9701 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
9702 Likewise.
9703 * src/tables.c (vector_number, tally, action_number,
9704 ACTION_NUMBER_MINIMUM): Likewise.
9705 * src/output.c (muscle_insert_short_int_table): Remove.

9707 2004-12-17 Akim Demaille <akim@epita.fr>
9708
9709 * data/lalr1.cc: Extensive Doxygenation.
9710 (error_): Rename as...
9711 (error): this, since it is visible to the user.
9712 Adjust callers.
9713 (Parser::message): Now an automatic variable from...

9718
9719 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
9720
9721 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
9722 Parenthesize rhs to avoid obscure problems with mistakes like
9723 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
9724 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9725 b4_rhs_location): Likewise.
9726 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9727 b4_rhs_location): Likewise.
9728
9729 2004-12-16 Akim Demaille <akim@epita.fr>
9730
9731 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
9732 yacc.c: be sure to stay within yycheck_.
9733 * tests/actions.at: Re-enable C++ tests.
9734
9735 2004-12-16 Akim Demaille <akim@epita.fr>
9736
9737 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
9738 real.
9739
9740 2004-12-16 Akim Demaille <akim@epita.fr>
9741
9742 Use #define to handle the %name-prefix.
9743
9744 * data/glr.c, data/yacc.c: Comment changes.
9745 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
9746 so that one can refer to yylex in the parser file, and have it
9747 renamed, as is the case with other skeletons.
9748
9749 2004-12-16 Akim Demaille <akim@epita.fr>
9750
9751 Move lalr1.cc internals into yy*.

9758 (user_token_number_max_, undef_token_, n_, len_, state_, nerrs_)
9759 (looka_, ilooka_, error_range_, nerrs_):

9769 these.
9770
9771 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
9772
9773 Fix some problems reported by twlevo at xs4all.
9774 * src/symtab.c (symbol_new): Report an error if the input grammar
9775 contains too many symbols. This is better than calling abort() later.
9776 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
9777 (struct node, struct graph):
9778 Rename member expand to stretch. All uses changed.
9779 (struct graph): Remove member layoutalgorithm. All uses removed.
9780 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
9781 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
9782 All uses changed.

9793
9794 2004-12-15 Akim Demaille <akim@epita.fr>
9795
9796 * data/lalr1.cc (lex_): Rename as...
9797 (yylex_): this.
9798 Move the trace here.
9799 Take the %name-prefix into account.
9800 Reported by Alexandre Duret-Lutz.
9801
9802 2004-12-15 Akim Demaille <akim@epita.fr>
9803
9804 Simplify the C++ parser constructor.
9805
9806 * data/lalr1.cc (debug_): Rename as...
9807 (yydebug_): so that the parser's internals are always in the yy*
9808 pseudo namespace.
9809 Adjust uses.
9810 (b4_parse_param_decl): Remove the leading comma as it is now only
9811 called as unique argument list.
9812 (Parser::Parser): Remove the constructor accepting a location and
9813 an initial debugging level.
9814 Remove from the other ctor the argument for the debugging level.
9815 (debug_level_type, debug_level, set_debug_level): New.
9816
9817 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
9818 constructor calls.
9819
9820 2004-12-15 Akim Demaille <akim@epita.fr>
9821
9822 Remove b4_root related material: failure experiment
9823 (which goal was to allow to derive from a class).
9824
9825 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
9826 definitions and uses.
9827
9828 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
9829
9830 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
9831 not 2, since it's not portable to subtract 1 from the start of an
9832 array. The new item 0 is never set or used. All uses changed.
9833
9834 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
9835 the default definition of YYLLOC_DEFAULT. Problem reported
9836 by Frank Heckenbach.
9837
9838 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
9839
9840 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
9841 the normal case and one for the error case. Just use the
9842 first one uniformly. Problem reported by Frank Heckenbach.
9843 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
9844 use exactly the same macro in both places.
9845 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
9846 so that the normal-case YYRHSLOC works for the error case too.
9847 All uses changed.
9848 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
9849 (YYLLOC_DEFAULT): Use the same macro as glr.c.
9850 * doc/bison.texinfo (Location Default Action): Don't claim that
9851 we have an array of locations. Use the same macro for both glr
9852 and lalr parsers. Mention YYRHSLOC. Mention what happens when
9853 the index is 0.
9854
9855 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9856

9865
9866 * src/scan-skel.l: Include "complain.h", for "fatal".
9867
9868 * src/relation.h (relation_print, relation_digraph):
9869 Relation sizes are of type relation_node, not size_t (this is
9870 merely a doc fix, since the two types are equivalent).
9871 (relation_transpose): Relation sizes are of type relation_node,
9872 not int.
9873 * src/relation.c: Likewise.
9874 (top, infinity): Now of type relation_node, not int.
9875 (traverse, relation_transpose): Use relation_node, not int.
9876
9877 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
9878 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
9879 (yyparse): Remove unused local introduced in 2004-10-25 patch.
9880
9881 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
9882 specifying whether the test should be skipped. Use it tp
9883 specify that the [%defines %skeleton "lalr1.cc"] tests currently
9884 fail on some hosts, and should be skipped.
9885
9886 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9887
9888 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
9889 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
9890 unless otherwise specified below.
9891
9892 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
9893 to allocate kernel_base, kernel_items, kernel_size, since
9894 they needn't be initialized to 0.
9895 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
9896 * src/closure.c (new_closure): Likewise, for itemset.
9897 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
9898 * src/lalr.c (set_goto_map): Likewise, for temp_map.
9899 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
9900 (build_relations): Likewise for edge, states1, includes.
9901 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
9902 * src/reader.c (packgram): Likewise, for ritem, rules.

9905 (relation_transpose): Likewise for new_R, end_R.
9906 * src/symtab.c (symbols_token_translations_init): Likewise for
9907 token_translations.
9908 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.

9912 (goto_actions): Likewise for state_count.
9913 (pack_table): Likewise for base, pos, check.
9914 (tables_generate): Likewise for width.
9915
9916 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
9917 for initial core. Just have a separate core, so we needn't worry
9918 about whether kernel_size and kernel_base are initialized.
9919
9920 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
9921 kernel_size, kernel_items): Remove unnecessary initialization.
9922 * src/conflicts.c (conflicts): Likewise.
9923 * src/derives.c (derives): Likewise.
9924 * src/muscle_tablc (muscle_insert): Likewise.
9925 * src/relation.c (relation_digraph): Likewise.
9926 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
9927 conflrow, conflict_table, conflict_list, table, check):
9928 Likewise.
9929
9930 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
9931 This is because all callers pass unsigned int.
9932 * src/closure.h (new_closure): Likewise.
9933
9934 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
9935 (build_relations): Initialize includes[i] in all cases.
9936 * src/reader.c (packgram): Always initialize rules[ruleno].prec
9937 and rules[ruleno].precsym. Initialize members in order.
9938 * src/relation.c (relation_transpose): Always initialize new_R[i]
9939 and end_R[i].
9940 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
9941
9942 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
9943 conflict_list[0] was always 0, but now it isn't initialized.
9944
9945 * src/table.c (table_grow): When conflict_table grew, the grown
9946 area wasn't cleared. Fix this.
9947
9948 * lib/.cvsignore: Add strdup.c, strdup.h.
9949 * m4/.cvsignore: Add strdup.m4.
9950
9951 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
9952
9953 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
9954 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
9955 GOTO_NUMBER_MAXIMUM, since we occasionally compute
9956 ngotos + 1 without checking for overflow.
9957 (build_relations): Use END_NODE, not -1, to denote end of edges.
9958 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
9959 build_relations): Use goto_number, not int, for goto numbers.
9960 * src/tables.c (save_column, default_goto): Likewise.
9961
9962 2004-11-23 Akim Demaille <akim@epita.fr>
9963
9964 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
9965 of #defining from yystype.
9966 Don't typedef yystype, C++ does not need it.
9967 This lets it possible to forward declare it as union.
9968
9969 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
9970
9971 * bootstrap (gnulib_modules): Add extensions.
9972 Problem reported by Jim Meyering.
9973
9974 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
9975
9976 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
9977 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
9978 src/system.h, src/tables.c: XFREE -> free, to accommodate
9979 recent change to gnulib xalloc.h.
9980 Problem reported by Jim Meyering.
9981
9982 2004-11-17 Akim Demaille <akim@epita.fr>
9983
9984 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
9985
9986 2004-11-17 Akim Demaille <akim@epita.fr>,
9987 Alexandre Duret-Lutz <adl@gnu.org>
9988
9989 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
9990 changes.
9991 (YYCDEBUG): Adjust.
9992 Use it instead of cdebug_.
9993 (Parser::debug_stream, Parser::set_debug_stream): New.
9994 (Parser::symprint_): Define cdebug_ for temporary backward
9995 compatibility.
9996 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
9997 debug_stream ().
9998
9999 2004-11-17 Akim Demaille <akim@epita.fr>
10000
10001 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
10002 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
10003 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
10004 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10005
10006 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
10007
10008 * data/glr.c (yyloc_default): Remove; not used.
10009 Problem reported by Frank Heckenbach.
10010
10011 2004-10-25 Akim Demaille <akim@epita.fr>
10012
10013 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
10014 Introduce another definition to address simple location arrays.
10015 (yyGLRStack): New member: yyerror_range.
10016 (yyrecoverSyntaxError, yyparse): Update it.
10017 (yyrecoverSyntaxError): Use it when shifting the error token to
10018 have an accurate range, equivalent to the one computed by both
10019 yacc.c and lalr1.cc.
10020 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
10021 that column numbers start at column 0, as per GNU Coding
10022 Standards, the others tests, and the doc.
10023 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
10024 Adjust to the above change (first column is 0).
10025 And adjust the location of the "<error>", now covering the whole
10026 line.
10027
10028 2004-10-22 Akim Demaille <akim@epita.fr>
10029 and Paul Eggert <eggert@cs.ucla.edu>
10030
10031 Remove some arbitrary limits on goto numbers and relations.
10032 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
10033 initial values, since they're never used.
10034 (set_goto_map): ngotos is now unsigned, so test for overflow
10035 by seeing whether it wraps around to zero.
10036 * src/lalr.h (goto_number): Now size_t, not short int.
10037 (GOTO_NUMBER_MAXIMUM): Remove.
10038 * src/relation.c (relation_print, traverse, relation_transpose):
10039 Check for END_NODE rather than looking at sign.
10040 * src/relation.h (END_NODE): New macro.
10041 (relation_node): Now size_t, not short int.
10042
10043 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
10044
10045 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
10046 keyword, not an identifier. Problem reported by Baron Schwartz in
10047 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
10048
10049 2004-10-11 Akim Demaille <akim@epita.fr>
10050
10051 * src/symtab.c (symbol_check_alias_consistency): Also check
10052 type names, destructors, and printers.
10053 Reported by Alexandre Duret-Lutz.
10054 Recode the handling of associativity and precedence in terms
10055 of symbol_precedence_set.
10056 Accept no redeclaration at all, not even equal to the previous
10057 value.
10058 (redeclaration): New.
10059 Use it to factor redeclaration complaints.
10060 (symbol_make_alias): Don't set the type of the alias, let
10061 symbol_check_alias_consistency do it as for other features.
10062 * src/symtab.h (symbol): Add new member prec_location, and
10063 type_location.
10064 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
10065 * tests/input.at (Incompatible Aliases): New.
10066
10067 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
10068
10069 .cvsignore fixes to accommodate gnulib changes,
10070 and the practice of naming build directories "_build".
10071 * .cvsignore: Add "_*". Sort.
10072 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
10073 * m4/.cvsignore: Add "*_gl.m4".
10074
10075 2004-10-06 Akim Demaille <akim@epita.fr>
10076
10077 * src/parse-gram.y (add_param): Fix the truncation of trailing
10078 spaces.
10079
10080 2004-10-05 Akim Demaille <akim@epita.fr>
10081
10082 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10083 whether the reducion was empty or not. This leaves room to
10084 improve the use of YYLLOC_DEFAULT in such a case.
10085 lalr1.cc is still experimental, so changing this is acceptable.
10086 And finally, there are probably not many users who changed the
10087 handling of locations in GLR, so changing is admissible too.
10088
10089 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
10090 empty reduction, set @$ to an empty location ending the previously
10091 stacked symbol.
10092 Adjust uses to make sure the code is triggered on empty
10093 reductions.
10094 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
10095 expected output: empty reductions have empty locations.
10096
10097 2004-09-29 Akim Demaille <akim@epita.fr>
10098
10099 * data/lalr1.cc: Move towards a more standard C++ coding style
10100 for templates: Class < T > -> Class<T>.
10101
10102 2004-09-29 Akim Demaille <akim@epita.fr>
10103
10104 * data/lalr1.cc: Reinstall the former ctor, for sake of
10105 compatibility, but warn it will be removed.
10106 Move towards a more standard C++ coding style (i.e., type *var ->
10107 type* var).
10108
10109 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
10110
10111 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
10112 since it's less likely to work if NULs are involved in the future.
10113
10114 2004-09-27 Akim Demaille <akim@epita.fr>
10115
10116 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
10117
10118 2004-09-27 Akim Demaille <akim@epita.fr>
10119
10120 * data/lalr1.cc (b4_parse_param_decl_1): New.
10121 (b4_parse_param_decl): Use it to have different names between attribute
10122 and argument names.
10123 (b4_cc_constructor_call): Likewise.
10124
10125 2004-09-24 Akim Demaille <akim@epita.fr>
10126
10127 * src/parse-gram.y (add_param): Strip the leading and trailing
10128 blanks from a formal argument declaration.
10129 (YY_LOCATION_PRINT): New.
10130
10131 2004-09-24 Akim Demaille <akim@epita.fr>
10132
10133 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
10134 after the location.
10135
10136 2004-09-24 Akim Demaille <akim@epita.fr>
10137
10138 * doc/bison.texinfo (Table of Symbols): Sort.
10139
10140 2004-09-21 Akim Demaille <akim@epita.fr>
10141
10142 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
10143 the useless parentheses.
10144 Suggested by Paul Eggert.
10145
10146 2004-09-20 Akim Demaille <akim@epita.fr>
10147
10148 Let the initial-action act on the look-ahead, and use it for the
10149 "initial push" (corresponding to an hypothetical beginning-of-file).
10150 And let lalr1.cc honor %initial-action.
10151
10152 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
10153 example.
10154 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10155 (Parser::Parser): Remove the ctor that used to initialize it.
10156 (Parser::parse): Like in the other skeletons, issue the "starting
10157 parse" message before any action.
10158 Honor %initial-action.
10159 Initialize the stacks with the lookahead.
10160 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10161 look-ahead.
10162 Push them in the stacks.
10163 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
10164
10165 2004-09-20 Akim Demaille <akim@epita.fr>
10166
10167 * doc/bison.texinfo (Initial Action Decl): New.
10168
10169 2004-09-20 Akim Demaille <akim@epita.fr>
10170
10171 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
10172 clearer criterion to define it.
10173 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
10174 When reducing on an empty RHS, use the latest stacked location as
10175 location.
10176 yylloc is not always available.
10177 * data/glr.c: Likewise.
10178 Also, honor initial-actions.
10179
10180 2004-09-20 Akim Demaille <akim@epita.fr>
10181
10182 * data/yacc.c (YY_LOCATION_PRINT): New.
10183 Define when we know YYLTYPE's structure, i.e., when the default
10184 YYLLOC_DEFAULT is used.
10185 * data/c.m4 (b4_yysymprint_generate): Use it.
10186 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
10187 value of the result.
10188 (error_start_): Replace with...
10189 (error_range_): this location array.
10190 This allows to replace code relying on the implementation of
10191 locations by portable code.
10192 * data/yacc.c (yylerrsp): Replace with...
10193 (yyerror_range): this.
10194 Every time a token is popped, update yyerror_range[0], to have an
10195 accurate location for the error token.
10196 * data/glr.c (YY_LOCATION_PRINT): New.
10197 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
10198 deference a pointer.
10199 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
10200 report the location in %printers.
10201
10202 * src/scan-skel.l: Instead of abort, report error messages to ease
10203 understanding skeleton scanning failures.
10204
10205 2004-09-16 Akim Demaille <akim@epita.fr>
10206
10207 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
10208 (iterator, const_iterator): these, to be more in the C++ spirit.
10209 Also, return reverse iterators so that when displaying the stack
10210 we display its bottom first.
10211 (Parser::stack_print_, Parser::reduce_print_): Match the messages
10212 from yacc.c.
10213 We should probably use vector here though.
10214
10215 2004-09-16 Akim Demaille <akim@epita.fr>
10216
10217 Have more complete shift traces.
10218
10219 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
10220 to report Shifts instead of ad hoc YYDPRINTF invocations,
10221 including for the error token.
10222 * data/lalr1.cc (symprint_): Output the location.
10223 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10224 output the location within the %printer.
10225 Activate GLR tests, at least to make sure they compile properly.
10226 They still don't pass though.
10227 * tests/calc.at: Adjust expect verbose output, since now "Entering
10228 state..." is on a different line than the "Shifting" message.
10229
10230 2004-09-08 Akim Demaille <akim@epita.fr>
10231
10232 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10233 Bison directive from the Bison file to the invocation of this
10234 macro, so that these directives are passed to
10235 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10236 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10237 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10238 the extra Bison directives instead of the whole series.
10239 Change the grammar so that there are recoverable errors, and
10240 unrecoverable errors. Now we can have the parser give up before
10241 consuming the whole input. As a result we now can observe that
10242 the lookahead is freed when needed.
10243 Change the parser source to parse argv[1] instead of a hard coded
10244 string.
10245 Simplify yylex, and give a value and location to EOF.
10246 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10247 passed directives already coded in the file.
10248 Add some tests to check the location of "error".
10249 For some tests, the C++ parser is correct, and not yacc.c.
10250 For other tests, they provide different, but unsatisfying, values,
10251 so keep the C++ value so that at least one parser is "correct"
10252 according to the test suite.
10253 (Actions after errors): Remove, this is subsumed by the
10254 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
10255
10256 2004-09-06 Akim Demaille <akim@epita.fr>
10257
10258 * data/lalr1.cc: Adjust the indentation of the labels.
10259 (Parser::pop): New.
10260 Use it.
10261
10262 2004-09-06 Akim Demaille <akim@epita.fr>
10263
10264 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
10265 argument, an informative message.
10266 Call YY_SYMBOL_PRINT.
10267 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
10268 * data/lalr1.cc (destruct_): Likewise.
10269 In addition, no longer depend on b4_yysymprint_generate and
10270 b4_yydestruct_generate to generate these functions, do it "by
10271 hand".
10272
10273 2004-09-03 Akim Demaille <akim@epita.fr>
10274
10275 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
10276 invoked, yydestruct the lookahead.
10277 * tests/calc.at (Calculator $1): Update the expected lengths of
10278 traces: there is an added line for the discarded lookahead.
10279 * doc/bison.texinfo (Destructor Decl): Some rewording.
10280 Define "discarded" symbols.
10281
10282 2004-09-02 Akim Demaille <akim@epita.fr>
10283
10284 * data/lalr1.cc (translate_, destruct_): No reason to be static.
10285
10286 2004-09-02 Akim Demaille <akim@epita.fr>
10287
10288 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
10289 (YYDSYMPRINTF): Rename as...
10290 (YY_SYMBOL_PRINT): this.
10291 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
10292 two.
10293 Use it instead of direct symprint_ calls.
10294 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
10295 one.
10296
10297 2004-09-02 Akim Demaille <akim@epita.fr>
10298
10299 * data/lalr1.cc (b4_yysymprint_generate): New.
10300 (symprint_): New member function, defined when YYDEBUG.
10301 Use it consistently instead of token/nterm debugging output by
10302 hand.
10303 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
10304 %printer calls to use cdebug_ when using lalr1.cc.
10305
10306 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
10307
10308 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
10309 with #ifdef YYDEBUG.
10310
10311 2004-08-26 Akim Demaille <akim@epita.fr>
10312
10313 * doc/bison.texinfo (Implementing Loops): Rename as...
10314 (Implementing Gotos/Loops): this.
10315
10316 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
10317
10318 Adjust to latest gnulib.
10319 * bootstrap (gnulib_modules): Add xalloc-die.
10320 Set LC_ALL=C so that file names sort consistently.
10321 Prefer the gnulib copies of gettext.m4, glibc21.m4,
10322 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
10323 uintmax_t.m4, ulonglong.m4.
10324 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
10325 po.m4 since we are now using _gl.m4 instead.
10326
10327 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
10328
10329 * src/scan-action.l: Remove. Scanning of semantic actions is
10330 handled in scan-gram.l.
10331
10332 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
10333
10334 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
10335
10336 * src/location.h (struct): The file member is a uniqstr.
10337 (equal_boundaries): Use UNIQSTR_EQ for comparison.
10338
10339 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
10340
10341 Fix bug with non-%union parsers that have printers or destructors,
10342 which led to a Bison core dump. Reported by Peter Fales in
10343 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
10344
10345 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
10346 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
10347 not to our own type.
10348 * src/output.c (symbol_destructors_output, symbol_printers_output):
10349 Don't assume %union.
10350 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
10351 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
10352 UNION-FLAG. All callers changed.
10353 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
10354 Use type char, not unsigned int, when declaring an array of char;
10355 this lets us remove a cast.
10356 (Printers and Destructors): Add non-%union test cases.
10357
10358 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10359
10360 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10361 GLR writeups. E.g., avoid frenchspacing and the future tense,
10362 change "lookahead" to "look-ahead", and change "wrt" to "with
10363 respect to".
10364
10365 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10366
10367 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
10368 New sections, split off from the GLR Parsers section. Put the new
10369 Simple GLR Parser near the start of the GLR section, for clarity.
10370 Rewrite connective text.
10371
10372 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
10373
10374 * doc/bison.texinfo (Simple GLR Parsers): New section.
10375
10376 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10377
10378 * NEWS, TODO, doc/bison.texinfo:
10379 Use "look-ahead" instead of "lookahead", to be consistent.
10380 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
10381 while we're fixing "look-ahead".
10382 * src/conflicts.c (shift_set): Renamed from shiftset.
10383 (look_ahead_set): Renamed from lookaheadset.
10384 * src/print.c: Likewise.
10385 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
10386 name for "lookahead".

10400
10401 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
10402
10403 * README: Update location of patched M4 distribution.
10404
10405 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
10406
10407 Don't assume the C++ compiler takes the same arguments as the C compiler
10408 (trivial change).
10409 * configure.ac (O0CXXFLAGS): New var.
10410 * tests/atlocal.in (CXXFLAGS): Use it.
10411
10412 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
10413
10414 Fix some "make check" problems with C++ reported by
10415 Albert Chin-A-Young for Tru64 C++ in this thread:
10416 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
10417
10418 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
10419 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10420 Output to a .cc file for C++, not to a .c file.
10421 * tests/calc.at (AT_CHECK_CALC): Likewise.
10422 * tests/regression.at (AT_CHECK_DANCER): Likewise.
10423 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
10424
10425 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
10426
10427 * tests/calc.at, tests/actions.at: Workaround for SGI

10429
10430 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10431
10432 Spent a few hours checking out which prerequisite versions the
10433 current sources actually require. I went all the way back to
10434 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10435 a seemingly endless set of combinations of versions more recent
10436 than that. The bottom line is that the current sources require
10437 fairly recent versions of the build tools, and it'll be some work
10438 to change this.
10439 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10440 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10441 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10442 Add comments explaining why those particular versions are
10443 currently needed.
10444
10445 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
10446 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10447 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10448
10449 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10450 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10451
10452 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10453
10454 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10455 0.11.5. Suggested by Bruno Haible.
10456 * bootstrap: Remove gettext version checking.
10457
10458 * doc/bison.texinfo (Decl Summary): Also mention that %union
10459 can depend on prerequisite types. Problem reported by Tim
10460 Van Holder.
10461
10462 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10463
10464 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10465 * README-alpha: Don't tell people not to package this.
10466
10467 * bootstrap: Don't assume $(...) works; use `...` instead.
10468 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
10469 gettext better.
10470
10471 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
10472 put into the -d output file, and mention what to do if YYSTYPE is
10473 defined as a macro.
10474
10475 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10476
10477 Undo change made earlier today: it caused autopoint to not bring
10478 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
10479 autopoint's.
10480
10481 * bootstrap: Check that gettext version matches what's in
10482 configure.ac. Warn users to ignore robots.txt ERROR 404.
10483 * bootstrap: Undo today's earlier change (logged below).
10484 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
10485
10486 The gettext version checking is causing more trouble than it's
10487 curing; remove it. Problem reported by Paul Hilfinger.
10488
10489 * bootstrap: Issue a warning that one can expect a message
10490 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
10491 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
10492
10493 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
10494
10495 Ensure that the C++ compiler used for testing actually works on a
10496 simple test program; if not, skip the C++-related tests. Problem
10497 reported by Vin Shelton in:
10498 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
10499
10500 * m4/cxx.m4: New file.
10501 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
10502 * tests/atlocal.in (BISON_CXX_WORKS): Add.
10503 * tests/local.at (AT_COMPILE_CXX): Use it.
10504
10505 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10506
10507 * data/glr.c (yylloc): Output this macro even if locations are not
10508 being generated, as the GLR parser needs it even in that case.
10509 Problem reported by Troy A. Johnson
10510 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
10511
10512 * configure.ac (AC_INIT): Update to 1.875e.
10513
10514 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10515
10516 * NEWS: Version 1.875d.
10517 * configure.ac (AC_INIT): Likewise.
10518 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
10519
10520 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
10521 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
10522 lalr1.cc runs afoul of the first, and the last two are no longer
10523 supported by GCC 3.4.0.
10524 * README: Mention GNU m4 1.4 or later; mention m4 patches.
10525 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
10526
10527 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
10528
10529 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
10530 unsigned int, for compatibility with latest gnulib hash module.
10531 * src/state.c (state_hash, state_hasher): Likewise.
10532 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.

10534
10535 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
10536
10537 * NEWS: Unescaped newlines are no longer allowed in char & strings.
10538
10539 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
10540 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
10541 character and string literals.
10542 (unexpected_end): New function.
10543 (unexpected_eof): Use it.
10544 (unexpected_newline): New function.
10545 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
10546 actions.
10547
10548 * NEWS: Document %expect-rr.
10549
10550 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):

10552 Remove more 'intl'-related files.
10553 Don't DEFUN AM_INTL_SUBDIR twice.
10554
10555 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
10556 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
10557 strtoul.c.
10558 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
10559 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
10560 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
10561 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
10562 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
10563 * src/.cvsignore: Add *.output.
10564
10565 * src/parse-gram.y: Put copyright notice inside %{ %} so it
10566 gets copied to the output file.
10567
10568 2004-04-28 Paul Eggert <eggert@twinsun.com>
10569
10570 Get files from the gnulib and po repositories, instead of relying
10571 on them being in our CVS. Upgrade to latest versions of gnulib
10572 and Automake.
10573
10574 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
10575 * bootstrap: Bootstrap from gnulib and po repositories.
10576 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
10577 * README-cvs: Document these changes. Remove version numbers from
10578 mentions of build tools, since they change so often. Mention Flex.
10579
10580 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
10581 (gl_USE_SYSTEM_EXTENSIONS): Add.
10582 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
10583 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
10584 does this for us.
10585 (AC_ISC_POSIX): Remove; we no longer support this
10586 ancient OS, as it gets in the way of latest Autoconf & gnulib.
10587 (AC_HEADER_STDC): Remove: we now assume C89 or better.
10588 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
10589 Do not check for C89 headers, except for locale.h which is used
10590 by the Yacc library and must port to K&R hosts.
10591 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
10592 Do not check for C89 functions, except for setlocale which is
10593 used by the Yacc library.
10594 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
10595 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

10598 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
10599 AM_GNU_GETTEXT): Remove; now done by:
10600 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
10601 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
10602 for us.
10603
10604 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
10605 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
10606 Define to empty, as gnulib.mk will do the rest for us.
10607 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
10608 for us.
10609 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
10610 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
10611
10612 * src/files.c: Include gnulib's xstrndup.h.
10613
10614 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
10615 (REALLOC): Use xnrealloc, for likewise.
10616 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
10617 (strnlen, memrchr): Remove decls; functions no longer used.
10618 Include <stpcpy.h>.
10619
10620 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

10640 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
10641 Remove, as these files are now generated automatically
10642 by bootstrap or automake.
10643
10644 * po/ChangeLog: Remove: all but one entry was a duplicate
10645 of this file, and I moved that 2000-11-02 entry here.
10646
10647 * config/.cvsignore: Add Makefile, depcomp, install-sh.
10648 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

10657 unlocked-io.h, xalloc.h, xmalloc.c, xstrdup.c, xstrndup.c,
10658 xstrndup.h.
10659 * m4/.cvsignore: Remove Makefile, Makefile.in. Add alloca.m4,
10660 dirname.m4, dos.m4, error.m4, getopt.m4, hash.m4, mbrtowc.m4,

10664 * src/.cvsignore: Remove *_.c.
10665
10666
10667 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
10668 support it. (The latest stable gzip doesn't.)
10669
10670 2004-04-27 Paul Eggert <eggert@twinsun.com>
10671
10672 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
10673 case, as stos_ is now used by destructors due to the 2004-02-09
10674 change.
10675
10676 Remove more K&R C support.
10677 * lib/libiberty.y (PARAMS): Remove. All uses removed.
10678 * lib/subpipe.c (errno): Remove decl.
10679 Include <stdlib.h> unconditionally.
10680 (EXIT_FAILURE): Remove macro.
10681 * src/complain.c (vfprintf, strerror): Remove.
10682 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
10683 unconditionally.
10684 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
10685 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
10686 (strchr, strspn, memchr): Remove decls.

10689 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
10690 unconditionally.
10691
10692 * src/complain.c (_): Remove useless defn, as system.h defines this.
10693
10694 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
10695 with latest obstack.h.
10696 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
10697 to procedure types, as obstack.h now does that for us.
10698 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
10699
10700 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
10701 so that this include file can stand alone.
10702 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
10703 does this now. Include subpipe.h first after config.h, to
10704 test whether it can stand alone.
10705
10706 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
10707 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
10708 unused declaration.
10709
10710 * tests/synclines.at (%union synch line): Put a dummy member in
10711 the union, because empty unions aren't allowed in C. Caught
10712 by GCC 3.4.0.
10713
10714 2004-04-13 Jim Meyering <jim@meyering.net>
10715
10716 * src/conflicts.c (conflicts_print): Correct format string typo:
10717 use `%%' to produce literal `%'. (trivial change)
10718
10719 2004-03-30 Paul Eggert <eggert@twinsun.com>
10720
10721 * src/getargs.c (version): Update copyright year to 2004.
10722
10723 * data/c.m4 (b4_int_type): Use 'short int' rather than
10724 'short', and similarly for 'long', 'unsigned', etc.
10725 * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum,
10726 yygetLRActions, yyprocessOneStack, yyrecoverSyntaxError,
10727 yy_yypstack, yydumpstack): Likewise.
10728 * data/lalr1.cc (user_token_number_max_, user_token_number_max_,
10729 translate_, seq_, [], pop, Slice, range_, operator+, operator+=):
10730 Likewise.
10731 * data/yacc.c (b4_int_type, yyss, YYSTACK_BYTES, yysigned_char,
10732 yy_stack_print, yyparse): Likewise.
10733 * doc/bison.texinfo (Prologue, Multiple Types): Likewise.

10748 * src/relation.h (relation_node): Likewise.
10749 * src/state.h (state_number, transitions, errs, reductions,
10750 struct state): Likewise.
10751 * src/symtab.h (symbol_number, struct symbol): Likewise.
10752 * src/tables.c (vector_number, tally, action_number,
10753 default_goto, goto_actions): Likewise.
10754 * tests/existing.at (GNU Cim Grammar): Likewise.
10755 * tests/regression.at (Web2c Actions): Likewise.
10756
10757 * src/output.c (muscle_insert_short_int_table): Renamed from

10759
10760 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
10761
10762 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
10763 (declaration): Replace expected_conflicts with expected_sr_conflicts.
10764 Add %expect-rr rule.
10765
10766 * src/scan-gram.l: Recognize %expect-rr.
10767
10768 * src/conflicts.h (expected_sr_conflicts): Rename from
10769 expected_conflicts.
10770 (expected_rr_conflicts): Declare.
10771
10772 * src/conflicts.c (expected_sr_conflicts): Rename from
10773 expected_conflicts.
10774 (expected_rr_conflicts): Define.
10775 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
10776 for GLR parsers.
10777 Use expected_sr_conflicts in place of expected_conflicts.
10778 Warn if expected_rr_conflicts used in non-GLR parser.
10779
10780 * doc/bison.texinfo: Add documentation for %expect-rr.
10781
10782 2004-03-08 Paul Eggert <eggert@gnu.org>
10783
10784 Add support for hex token numbers. Suggested by Odd Arild Olsen in
10785 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
10786
10787 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
10788 in lalr1.cc.
10789 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
10790 * src/scan-gram.l (scan_integer): New function.
10791 ({int}): Use it.
10792 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
10793 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
10794 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
10795 Say "long int", not "long", for uniformity with GNU style.
10796
10797 2004-02-25 Paul Eggert <eggert@twinsun.com>
10798
10799 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
10800 compilers. This fixes a problem with Intel's C++ compiler being
10801 chatty, reported by Guido Trentalancia in
10802 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
10803
10804 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
10805
10806 Support %destructor and merge error locations in lalr1.cc.
10807
10808 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
10809 (Parser::stos_): Define unconditionally.
10810 (Parser::destruct_): New method. Generate its body with
10811 b4_yydestruct_generate.
10812 (Parser::error_start_): New attribute.
10813 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
10814 token which are discarded.
10815 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
10816 error_start_ when erroneous token are discarded.
10817 (Parser::parse) <yyerrlab1>: Compute the location of the error
10818 token so that it covers all the discarded tokens.
10819 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
10820 it can be called with `%skeleton "lalr1.cc"', and do that.
10821
10822 2004-02-02 Paul Eggert <eggert@twinsun.com>
10823
10824 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
10825 $(top_srcdir)/lib and ../lib. This fixes a bug reported
10826 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
10827 There's no need to mention top_builddir since Automake does that
10828 for us.
10829 (INCLUDES): Remove, as Automake says it's obsolescent.
10830 Contents migrated into AM_CPPFLAGS as described above.
10831 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
10832
10833 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10834
10835 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
10836 (yyreportSyntaxError): Handle case where lookahead token is
10837 YYEMPTY.
10838
10839 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10840
10841 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
10842 resulting parsers are compilable with C++.
10843
10844 2003-12-23 Paul Eggert <eggert@twinsun.com>
10845
10846 * config/depcomp, config/install-sh: Sync with Automake 1.8.
10847 * src/output.c (output_skeleton): Rename local var.
10848 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
10849 Bison tokens, as this runs afoul of the 2003-10-07 change that
10850 disallowed NUL bytes in character constants or string literals.
10851
10852 * tests/local.at: Require Autoconf 2.59's Autotest.
10853 * tests/testsuite.at: Don't include local.at, since we now assume
10854 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
10855 including it.
10856 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
10857 multiple inclusion warnings.
10858
10859 2003-12-02 Akim Demaille <akim@epita.fr>
10860
10861 * doc/bison.texinfo (How Can I Reset the Parser): More about start
10862 conditions.

10869 2003-10-07 Paul Eggert <eggert@twinsun.com>
10870
10871 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
10872 if testsuite doesn't exist.
10873
10874 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
10875 literals, unfortunately.
10876 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
10877 Complain about NUL bytes in character constants or string literals.

10879 2003-10-05 Paul Eggert <eggert@twinsun.com>
10880
10881 * NEWS: Don't document %no-default-prec, as it's still
10882 too experimental.
10883 * doc/bison.texinfo: Document %no-default-prec only if
10884 the defaultprec flag is set. Normally it's not.
10885
10886 2003-10-04 Paul Eggert <eggert@twinsun.com>
10887
10888 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
10889 non-modifiable lvalue, instead of a modifiable one.
10890 * doc/bison.texinfo (Actions): Document that $$ can
10891 be assigned to. Do not claim that $$ and $N are
10892 array element references: user code should not rely on this.

10931 GCC warnings.
10932
10933 2003-08-26 Akim Demaille <akim@epita.fr>
10934
10935 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
10936 "<\#" to avoid magic from Gnus when posting parts of this script.
10937
10938 2003-08-26 Akim Demaille <akim@epita.fr>
10939
10940 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
10941 (Parser::parse): here.
10942 Adjust: nerrs and errstatus is now replaced by...
10943 (Parser::nerrs_, Parser::errstatus_): New.
10944

10953
10954 When reducing initial empty rules, Bison parser read an initial
10955 location that is not defined. This results in garbage, and that
10956 affects Bison's own parser. Therefore we need (i) to extend Bison
10957 to support a means to initialize this location, and (ii) to use
10958 this CVS Bison to fix CVS Bison's parser.
10959
10960 * src/reader.h, reader.c (epilogue_augment): Remove, replace
10961 with...
10962 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
10963 * src/parse-gram.y: Adjust.
10964 (%initial-action): New.
10965 (%error-verbose): Since we require CVS Bison, there is no reason
10966 not to use it.
10967 * src/scan-gram.l: Adjust.
10968 * src/Makefile.am (YACC): New, to make sure we use our own parser.
10969 * data/yacc.c (yyparse): Use b4_initial_action.
10970
10971 2003-08-25 Akim Demaille <akim@epita.fr>
10972
10973 * doc/bison.texinfo: Don't promote stdout for error messages.
10974
10975 2003-08-25 Akim Demaille <akim@epita.fr>
10976
10977 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
10978 From Alexandre Duret-Lutz.
10979
10980 2003-08-25 Akim Demaille <akim@epita.fr>
10981
10982 Version 1.875c.
10983
10984 2003-08-25 Akim Demaille <akim@epita.fr>
10985
10986 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
10987 Use them.
10988
10989 2003-08-25 Akim Demaille <akim@epita.fr>
10990
10991 * data/lalr1.cc (Parser::reduce_print_): New.
10992 Use it.
10993
10994 2003-08-25 Akim Demaille <akim@epita.fr>
10995
10996 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
10997 error recovery loops. This patch is based on
10998 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
10999 Also, augment the similarity between lalr1.cc and yacc.c.
11000 Note: the locations of error recovery rules are not correct yet.
11001
11002 * data/lalr1.cc: Comment changes to augment the similarity between
11003 lalr1.cc and yacc.c.
11004 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
11005 (yyerrlab1): Remove, but where it used to be (now the bottom part of
11006 yyerrlab), when hitting EOF, pop the whole stack here instead of
11007 merely falling thru the default error handling mechanism.
11008 (yyerrorlab): New label, with the old contents of YYERROR,
11009 plus the following change: pop the stack of rhs corresponding
11010 to the production that invoked YYERROR. That is how Yacc
11011 behaves (required by POSIX).
11012 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
11013 fail.
11014
11015 2003-08-25 Akim Demaille <akim@epita.fr>
11016
11017 Tune local.at so that people can "autom4te -l autotest calc.at -o
11018 calc" for instance, to extract a sub test suite.
11019
11020 * tests/testsuite.at: Move the initialization, Autotest version
11021 requirement, and AT_TESTED invocation into...
11022 * tests/local.at: here.
11023 * tests/testsuite.at: Include it for compatibility with Autoconf
11024 2.57.
11025 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
11026 be ignore.
11027
11028 2003-08-04 Paul Eggert <eggert@twinsun.com>
11029
11030 Rework code slightly to avoid gcc -Wtraditional warnings.
11031 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
11032 The returned value is now stored in *YY0. All callers changed.
11033 * src/output.c (merge_output): Adjust to the above change.
11034
11035 2003-07-26 Paul Eggert <eggert@twinsun.com>
11036
11037 * data/glr.c (YYASSERT): New macro.
11038 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
11039 yyresolveStates, yyprocessOneStack):
11040 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
11041 Derived from a suggestion by Frank Heckenbach.
11042
11043 2003-07-25 Paul Eggert <eggert@twinsun.com>
11044
11045 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
11046 for portability to K&R C (after ansi2knr, presumably). See
11047 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
11048 by Frank Heckenbach, though I have omitted the structure-initialization
11049 part of his glr-knr.diff patch since I recall that the Portable
11050 C Compiler didn't require that change.
11051
11052 Let the user specify how to allocate and free memory.
11053 Derived from a suggestion by Frank Heckenbach in
11054 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
11055 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
11056 All uses of free, malloc, realloc changed to use these macros,
11057 and unnecessary casts removed.
11058 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
11059
11060 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
11061
11062 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
11063 use s.empty() rather than s == "" to test for empty string; see
11064 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
11065 (trivial change)
11066
11067 2003-06-25 Akim Demaille <akim@epita.fr>
11068
11069 * config/depcomp, config/install-sh: Update from masters.
11070
11071 2003-06-20 Paul Eggert <eggert@twinsun.com>
11072
11073 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
11074 and return properly parenthesized result.
11075 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
11076 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
11077 Remove unnecessary parentheses from uses.
11078 * doc/bison.texinfo (Location Default Action): Describe the
11079 conventions for parentheses.
11080
11081 2003-06-19 Paul Eggert <eggert@twinsun.com>
11082
11083 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
11084 yyreportTree): Do not assume that size_t is the same width as int,
11085 when printing sizes. Print sizes using an unsigned format.
11086 Problem reported by Frank Heckenbach in
11087 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
11088
11089 Port to Forte Developer 7 C compiler.
11090 * data/glr.c (struct YYLTYPE): If locations are not being used,
11091 declare a single dummy member, as empty structs do not conform
11092 to the C standard.
11093 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
11094 the Forte Developer 7 C compiler complains that end-of-loop
11095 code is not reached.
11096
11097 2003-06-17 Paul Eggert <eggert@twinsun.com>
11098
11099 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
11100 avoid warnings from picky compilers about redefinition of PARAMS.
11101
11102 2003-06-17 Paul Eggert <eggert@twinsun.com>
11103
11104 Version 1.875b.
11105
11106 * NEWS: Document 1.875b.
11107
11108 * lib/bbitset.h: Do not include config.h; that's the includer's job.
11109 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
11110 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
11111 Don't use 'index' in comments, as it's a builtin fn on some hosts.
11112 * lib/bitset_stats.c: Include gettext.h unconditionally, as
11113 per recent gettext manual's suggestion.
11114 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
11115 Use prototypes, not old-style definitions.
11116 * lib/lbitset.c (lbitset_unused_clear): Likewise.
11117 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
11118 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
11119 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

11122 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
11123 vbitset_or_and_cmp, vbitset_copy): Likewise.

11128 (ATTRIBUTE_NORETURN): Remove.
11129 (ATTRIBUTE_UNUSED): Define unconditionally.
11130
11131 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
11132 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>

11137 from libbitset.
11138
11139 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
11140 `How Can I Reset @code{yyparse}', since texinfo does not allow
11141 arbitrary @ in node names.
11142
11143 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
11144 shouldn't be needed according to the gettext 0.12.1 documentation
11145 but which seem to be needed anyway: codeset.m4 glibc21.m4
11146 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
11147 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
11148 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
11149
11150 * lib/.cvsignore: Add stdbool.h.
11151 * m4/.cvsignore: Add nls.m4, po.m4.
11152
11153 Upgrade to CVS gnulib.
11154 * stdbool_.h: File renamed from stdbool.h.in.
11155 * configure.ac (AM_STDBOOL_H): Invoke this instead of
11156 AC_HEADER_STDBOOL.
11157 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
11158 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
11159 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
11160 (MOSTLYCLEANFILES): New var.
11161 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
11162 (stdbool.h): New rule.
11163 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
11164 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
11165 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
11166 m4/quote.m4: Upgrade to today's gnulib.
11167
11168 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
11169 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
11170 the tests right now.
11171 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
11172 yyerror are declared before use; C99 requires this.
11173
11174 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11175
11176 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
11177 first.
11178 (yyrecoverSyntaxError): Correct the logic for setting and testing
11179 yyerrState.
11180 Correct comment on handling EOF.
11181 Allow states with only a default reduction, rather than failing
11182 (I can't quite reconstruct why these were not allowed before).
11183
11184 Fixes to avoid problem that $-N rules in GLR parsers can cause
11185 buffer overruns, corrupting state.
11186
11187 * src/output.c (prepare_rules): Output max_left_semantic_context
11188 definition.
11189 * src/reader.h (max_left_semantic_context): New variable declaration.
11190 * src/scan-gram.l (max_left_semantic_context): Define.
11191 (handle_action_dollar): Update max_left_semantic_context.
11192 * data/glr.c (YYMAXLEFT): New definition.
11193 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
11194 (yyresolveAction): Ditto.
11195
11196 Fixes to problems with location handling in GLR parsers reported by
11197 Frank Heckenbach (2003/06/05).
11198
11199 * data/glr.c (YYLTYPE): Make trivial if locations not used.
11200 (YYRHSLOC): Add parentheses, and define only if locations used.
11201 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
11202 locations not used.
11203 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
11204 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
11205
11206 * tests/cxx-type.at: Exercise location information; update tests
11207 to differentiate output with and without locations.
11208 Remove forward declarations of yylex and yyerror---caused errors
11209 because default YYLTYPE not yet defined.
11210 Change semantic actions to compute strings, rather than printing
11211 them directly (to test proper passing of semantics values). Change
11212 output to prefix notation and update test data and expected results.
11213 (yylex): Track locations.
11214 (stmtMerge): Return value rather than printing, and include arguments
11215 in value.
11216
11217 2003-06-03 Paul Eggert <eggert@twinsun.com>
11218
11219 Avoid warnings generated by GCC 2.95.4 when Bison is
11220 configured with --enable-gcc-warnings.
11221 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
11222 yy::]b4_parser_class_name[::translate_,
11223 yy::Stack::operator[] (unsigned),
11224 yy::Stack::operator[] (unsigned) const,
11225 yy::Slice::operator[] (unsigned),
11226 yy::Slice::operator[] (unsigned) const):
11227 Rename local vars to avoid warnings.
11228 * tests/glr-regression.at (Improper handling of embedded actions
11229 and $-N in GLR parsers): Remove unused local variable from yylex.
11230 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11231 (void) as arg when not pure, since we now assume C89 when building
11232 Bison. Pacify GCC by using parameter.
11233
11234 2003-06-02 Paul Eggert <eggert@twinsun.com>
11235
11236 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11237 yy::Location::lines, yy::Location::columns): Rename arguments
11238 to avoid shadowing; this removes a warning generated by GCC 3.3.
11239
11240 2003-06-01 Paul Eggert <eggert@twinsun.com>
11241
11242 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11243 to g++, as GCC 3.3 complains if you do it.
11244 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11245 everything that WARNING_CFLAGS has, except omit warnings
11246 not suitable for C++.
11247 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11248 * tests/atlocal.in (CXXFLAGS): New var.
11249 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11250
11251 Fix a GLR parser bug I reported in February; see
11252 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
11253 The problem was that GLR parsers did not conform to the C standard,
11254 because actions like { $1 = $2 + $3; } expanded to expressions
11255 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11256 to a local variable. The C standard says that expressions
11257 like (var = f ()) + (var = f ()) have undefined behavior.
11258 Another problem was that GCC sometimes issues warnings that
11259 yyfill and its parameters are unused.
11260
11261 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11262 as possibly unused.
11263 (yyfill): New function.
11264 (YYFILL): Use it.
11265 (yyuserAction): Change type of yynormal to bool, so that it matches
11266 the new yyfill signature. Mark it as possibly unused.
11267
11268
11269 Follow up on a bug I reported in February, where a Bison-generated
11270 parser can loop. Provide a test case and a fix for yacc.c. I
11271 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11272 The original bug report is in:
11273 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
11274
11275 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11276 macro's size was becoming unwieldy.
11277 (yyerrlab): Do not discard an empty lookahead symbol, as this
11278 might destroy garbage.
11279 (yyerrorlab): New label, with the old contents of YYERROR,
11280 plus the following change: pop the stack of rhs corresponding
11281 to the production that invoked YYERROR. That is how Yacc
11282 behaves, and POSIX requires this behavior.
11283 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11284 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11285 Define 'alarm' to do nothing if unistd.h is not available.
11286 Add a new rule "exp: '-' error;" to test the above change to
11287 data/yacc.c. Use 'alarm' to abort any test taking longer than
11288 10 seconds, as it's probably looping.
11289 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11290 Also, the new yacc.c generates two fewer diagnostics for an
11291 existing test.
11292
11293 2003-05-24 Paul Eggert <eggert@twinsun.com>
11294
11295 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
11296 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
11297 This fixes a problem reported by John Bowman when the Compaq/HP
11298 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
11299 -ansi -Wall -gall).
11300 * data/yacc.c (union yyalloc): Likewise.
11301 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
11302
11303 Switch from 'int' to 'bool' where that makes sense.
11304
11305 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
11306 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
11307 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,

11318 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
11319 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
11320 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
11321 bitset_stats_or_and_cmp): Likewise.
11322 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
11323 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
11324 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
11325 ebitset_xor_cmp): Likewise.
11326 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
11327 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
11328 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
11329 lbitset_xor_cmp): Likewise.
11330 * lib/bbitset.h: Include <stdbool.h>.
11331 (struct bitset_vtable): The following members now return bool, not
11332 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
11333 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
11334 or_and_cmp).
11335 * src/conflicts.c (count_rr_conflicts): Likewise.
11336 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
11337 All uses changed.
11338 * lib/ebitset.c (ebitset_obstack_init): Likewise.
11339 * lib/lbitset.c (lbitset_obstack_init): Likewise.
11340 * src/getargs.c (debug_flag, defines_flag, locations_flag,
11341 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
11342 graph_flag): Likewise.
11343 * src/getargs.h (debug_flag, defines_flag, locations_flag,
11344 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
11345 graph_flag): Likewise.
11346 * src/output.c (error_verbose): Likewise.

11348 * src/reader.c (start_flag, typed): Likewise.
11349 * src/reader.h (typed): Likewise.
11350 * src/getargs.c (LOCATIONS_OPTION): New constant.
11351 (long_options, getargs): Use it.
11352 * src/lalr.c (build_relations): Use bool, not int.
11353 * src/nullable.c (nullable_compute): Likewise.
11354 * src/print.c (print_reductions): Likewise.
11355 * src/tables.c (action_row, pack_vector): Likewise.
11356 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
11357 * src/output.c (prepare): Use it.
11358 * src/output.c (token_definitions_output,
11359 symbol_destructors_output, symbol_destructors_output): Use string,
11360 not boolean integer, to keep track of whether to output separator.
11361 * src/print_graph.c (print_core): Likewise.
11362 * src/state.c (state_rule_lookaheads_print): Likewise.
11363
11364 * config/install-sh: Sync from automake 1.7.5.
11365
11366 2003-05-14 Paul Eggert <eggert@twinsun.com>
11367
11368 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11369 semicolon after a grammar declaration, in the interest of possible
11370 future changes to the Bison input language.
11371 Do not allow a stray semicolon at the start of the grammar.
11372 (rhses.1): Allow one or more semicolons after any rule, including
11373 just before "|" as required by POSIX.
11374 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11375 grammar.
11376
11377 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11378
11379 %parse-param support for lalr1.cc.
11380
11381 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11382 b4_cc_constructor_calls, b4_cc_constructor_call,
11383 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11384 definitions.
11385 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11386 parse-param arguments.
11387 (yy::b4_parser_class_name): Declare instance variables to
11388 hold parse-param arguments.
11389 * tests/calc.at: s/value/semantic_value/ because value clashes
11390 with a member of yy::b4_parser_class_name. Adjust C++ code
11391 to handle %parse-param. Enable %parse-param test in C++.
11392
11393 2003-05-12 Paul Eggert <eggert@twinsun.com>
11394
11395 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11396 English a bit. Fix fclose typo. Change "const char" to "char
11397 const", and use ANSI C rather than K&R for "main". Suggest
11398 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11399 and suggest yy_switch_to_buffer.
11400
11401 2003-05-05 Paul Eggert <eggert@twinsun.com>
11402
11403 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11404 C89. This avoids a diagnostic on compilers that define __STDC__
11405 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11406 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11407
11408 2003-05-03 Paul Eggert <eggert@twinsun.com>
11409
11410 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11411 Do not overrun array bounds.
11412 This should fix a bug reported today by Olatunji Oluwabukunmi in
11413 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11414
11415 2003-04-29 Akim Demaille <akim@epita.fr>
11416
11417 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11418 * src/getargs.c, src/getargs.h: here, as bool, not int.
11419 (nondeterministic_parser): New.
11420 * src/parse-gram.y, src/scan-gram.l: Support
11421 %nondeterministic-parser.
11422 * src/output.c (prepare): Use nondeterministic_parser instead
11423 of glr_parser where appropriate.
11424 * src/tables.c (conflict_row, action_row, save_row)
11425 (token_actions, token_actions, pack_vector): Ditto.
11426
11427 2003-04-29 Akim Demaille <akim@epita.fr>
11428
11429 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11430
11431 2003-04-29 Akim Demaille <akim@epita.fr>
11432
11433 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11434 with %pure-parser and %locations to exercise the patch from Yakov
11435 Markovitch below.
11436
11437 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11438
11439 * data/yacc.c: (b4_lex_param): Corrected for the case where
11440 %lex-param is provided and %pure-parser isn't.
11441
11442 2003-04-27 Paul Eggert <eggert@twinsun.com>
11443
11444 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11445 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11446 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11447 if it is not defined.
11448 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11449
11450 2003-04-26 Paul Eggert <eggert@twinsun.com>
11451
11452 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11453 Declare to be of type suitable for the ninf value itself, not of
11454 type suitable for the corresponding table, since the latter might
11455 be unsigned but the ninf value might be negative. This fixes a
11456 bug reported by Alexandre Duret-Lutz in
11457 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11458
11459 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11460 invokes it. We shouldn't invoke it twice because it will attempt
11461 to put error.o in the archive twice. This fixes a glitch reported
11462 by Martin Mokrejs in
11463 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11464
11465 2003-04-21 Paul Eggert <eggert@twinsun.com>
11466
11467 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
11468 to gnulib.
11469
11470 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
11471
11472 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
11473 Fix obvious typo that results in uncompilable GLR parsers
11474 when both %pure-parser and %locations are used. (trivial change)
11475
11476 2003-04-17 Paul Eggert <eggert@twinsun.com>
11477
11478 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
11479 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
11480 Do not insert the expected token via unput, as this runs afoul
11481 of a POSIX-compatibility bug in flex 2.5.31.
11482 All uses changed to BEGIN the parent state,
11483 since we no longer insert the expected token via unput.
11484 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
11485 that is no longer emitted after the above change.
11486
11487 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
11488 the first one. This change is from Paul Hilfinger, and it fixes
11489 regression reported by Werner Lemberg in
11490 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
11491
11492 (resolve_sr_conflict): Don't invoke state_errs_set
11493 unless one or more tokens have been explicitly made errors.
11494 Otherwise, the above change causes Bison to abort.
11495
11496 * tests/existing.at (GNU pic Grammar): New test case, taken from
11497 Lemberg's email.
11498
11499 2003-03-31 Akim Demaille <akim@epita.fr>
11500
11501 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
11502
11503 2003-03-31 Akim Demaille <akim@epita.fr>
11504
11505 * src/output.c (prepare_symbols): Avoid trailing spaces in the
11506 output.
11507
11508 2003-03-31 Akim Demaille <akim@epita.fr>
11509
11510 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
11511 From Paul Hilfinger.
11512
11513 2003-03-29 Akim Demaille <akim@epita.fr>
11514
11515 * m4/error.m4: Do not put under dynamic conditions some code which
11516 expansion is under static control.
11517
11518 2003-03-29 Akim Demaille <akim@epita.fr>
11519
11520 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
11521
11522 2003-03-29 Akim Demaille <akim@epita.fr>
11523
11524 * doc/bison.texinfo (Strings are Destroyed): New.
11525
11526 2003-03-13 Paul Eggert <eggert@twinsun.com>
11527
11528 * .cvsignore: Add configure.lineno.
11529 * src/.cvsignore: Add yacc.
11530 * tests/.cvsignore: Add testsuite.log.
11531 * doc/fdl.texi: Sync with latest FSF version.
11532
11533 2003-03-12 Paul Eggert <eggert@twinsun.com>
11534
11535 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
11536 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
11537 cursor, instead of leaving it undefined. This fixes a bug
11538 reported by Tim Van Holder in
11539 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
11540 * tests/input.at (Torturing the Scanner): Test the scanner on
11541 an empty input file, which was Tim Van Holder's test case.
11542
11543 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
11544 <sys/resource.h> can be included, include sys/time.h and
11545 sys/times.h first, if available. This works around the SunOS
11546 4.1.4 porting bug reported by Bruce Becker in
11547 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
11548
11549 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
11550 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
11551 AC_HEADER_SYS_WAIT.
11552
11553 Merge changes from gnulib. This was prompted because the CVS
11554 snapshot didn't build on Solaris 7 due to strnlen problems.
11555
11556 These changes need to be merged back into gnulib:
11557 * lib/hash.c: Include <stdbool.h> unconditionally.
11558 * m4/onceonly.m4 (m4_quote): New macro.
11559 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
11560 Quote AC_FOREACH variable-expansions properly.
11561 The 2003-01-03 obstack.h change also needs merging.
11562 {end of changes requiring merging}
11563
11564 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
11565 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

11568 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
11569 New files, imported from gnulib.
11570 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
11571 above.
11572
11573 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
11574 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
11575 gnulib sources.
11576
11577 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
11578 Add.
11579 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
11580 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
11581 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
11582 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
11583 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
11584 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
11585 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
11586 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
11587 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
11588 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
11589 (jm_PREREQ_ARGMATCH): Remove.
11590 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
11591 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
11592
11593 * src/system.h: Include <stdbool.h> unconditionally.
11594
11595 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
11596 assuming at least C89 in the bitset code for some time now.
11597
11598 2003-03-03 Akim Demaille <akim@epita.fr>
11599
11600 * ro.po: New.
11601
11602 2003-03-02 Akim Demaille <akim@epita.fr>
11603
11604 * doc/bison.texinfo (Table of Symbols): Reactivate the
11605 documentation for %lex-param, and %parse-param.
11606
11607 2003-03-02 Akim Demaille <akim@epita.fr>
11608
11609 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
11610 generate verbose error messages.
11611 Use the number of tokens as an upper bound in yytname, as it
11612 cannot be a non terminal.
11613
11614 2003-03-02 Akim Demaille <akim@epita.fr>
11615
11616 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
11617 message.
11618
11619 2003-03-02 Akim Demaille <akim@epita.fr>
11620
11621 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
11622 Use them to exercise yycheck overrun.
11623 Based on Andrew Suffield's grammar.
11624
11625 2003-03-02 Akim Demaille <akim@epita.fr>
11626
11627 Create tests/local.at for Bison generic testing macros.
11628
11629 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
11630 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
11631 This new file.
11632 * tests/calc.at (AT_CHECK_CALC): Adjust.
11633 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
11634 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
11635 * tests/local.at: here.
11636 (AT_COMPILE_CXX): Tags the tests using it as c++.
11637 Ignore the test if CXX is not functional.
11638
11639 2003-03-01 Paul Eggert <eggert@twinsun.com>
11640
11641 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
11642 not loc->end, since loc->end might contain garbage and this leads
11643 to undefined behavior on some platforms.
11644 (id_loc, token_start): Use (IF_LINTed) initial values that do not
11645 depend on *loc, so that the reader doesn't give the the false
11646 impression that *loc is initialized.
11647 (<INITIAL>"%%"): Do not bother setting code_start, since its value
11648 does not survive the return.
11649
11650 2003-03-01 Akim Demaille <akim@epita.fr>
11651
11652 * src/scan-gram.l (code_start): Always initialize it when entering
11653 into yylex, as SC_EPILOGUE is activated *before* the corresponding
11654 yylex invocation. An alternative would be making it static, but
11655 then it starts with the second %%'s beginning, instead of its end.
11656
11657 2003-02-28 Paul Eggert <eggert@twinsun.com>
11658
11659 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
11660 around a UnixWare 7.1.1 porting bug reported by John Hughes in
11661 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
11662
11663 2003-02-26 Paul Eggert <eggert@twinsun.com>
11664
11665 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
11666 Remove Sequent/Pyramid discussion (nobody uses them any more).
11667 Merge VMS and MS-DOS discussion; these ports may well be dead
11668 but let's keep mentioning them for now. Put <> around email
11669 addresses. Add copyright notice.
11670
11671 2003-02-24 Paul Eggert <eggert@twinsun.com>
11672
11673 * data/glr.c (yy_reduce_print): yylineno -> yylno,
11674 to avoid collision with flex use of yylineno.
11675 Problem reported by Bruce Lilly in
11676 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

11682 2003-02-21 Akim Demaille <akim@epita.fr>
11683
11684 * data/lalr1.cc: Use temporary variables instead of casts to
11685 change integer types.
11686 Suggested by Paul Eggert.
11687
11688 2003-02-21 Akim Demaille <akim@epita.fr>
11689
11690 * doc/bison.texinfo: Use "location" consistently to refer to @n,
11691 to avoid confusions with lalr1.cc's notion of Position.
11692 Suggested by Paul Eggert.
11693
11694 2003-02-20 Akim Demaille <akim@epita.fr>
11695
11696 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
11697 before initial_columns.
11698 (location.hh): Use consistent variable names when defining the
11699 operator<<.
11700 Use "last" so that we subtract from Positions, not from unsigned.
11701
11702 2003-02-20 Akim Demaille <akim@epita.fr>
11703
11704 * data/lalr1.cc (position.hh): New subfile, including the extended

11711
11712 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
11713 AT_YACC_IF.
11714 Redefine AT_YYERROR_SEES_LOC_IF using it.
11715 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
11716 not defined.
11717 Don't use the location in yy::Parser::error_ and
11718 yy::Parser::print_ when not %locations.
11719 Activate more lalr1.cc tests.
11720
11721 2003-02-19 Akim Demaille <akim@epita.fr>
11722
11723 * data/lalr1.cc: When displaying a line number, be sure to make it
11724 an int.
11725
11726 2003-02-19 Akim Demaille <akim@epita.fr>
11727
11728 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
11729 Remove, useless.
11730 (YYABORT, YYACCEPT, YYERROR): New.
11731 * tests/calc.at: Renable the lalr1.cc test.
11732
11733 2003-02-19 Akim Demaille <akim@epita.fr>
11734
11735 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
11736 error recovery, mixing with/without pops and discarding of the
11737 lookahead.
11738 Exercise YYERROR.
11739 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
11740
11741 2003-02-17 Paul Eggert <eggert@twinsun.com>
11742
11743 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
11744 * tests/testsuite.at (AT_COMPILE): Use them.
11745 This fixes the testsuite problem reported by Robert Lentz in
11746 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
11747
11748 2003-02-12 Paul Eggert <eggert@twinsun.com>
11749
11750 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
11751 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
11752 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
11753 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
11754 Check for malloc failure, for consistency with yacc.c.
11755 (yytname_size): Remove, for consistency with yacc.c.
11756
11757 The bug still remains in data/lalr1.cc, as I didn't have time
11758 to fix it there.
11759
11760 2003-02-06 Akim Demaille <akim@epita.fr>
11761
11762 * configure.ac (GXX): Rename as...
11763 (CXX): this, to keep the original Autoconf semantics.
11764 Require 2.57.
11765 * data/lalr1.cc: Fix b4_copyright invocations.
11766 If YYDEBUG is not defined, don't depend upon name_ being defined.
11767 (location.hh): Include string and iostream.
11768 (Position::filename): New member.
11769 (Position::Position ()): New.
11770 (operator<< (Position)): New.
11771 (operator- (Position, int)): New.
11772 (Location::first, Location::last): Rename as...
11773 (Location::begin, Location::end): these, to mock the conventional
11774 iterator names.
11775 (operator<< (Location)): New.
11776 * tests/atlocal.in (CXX): New.
11777 * tests/testsuite.at (AT_COMPILE_CXX): New.
11778 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
11779 locations in a more synthetic way.
11780 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
11781 lalr1.cc is used.
11782 Adjust the C locations to match those from Emacs: first column is
11783 column 0.
11784 Change all the expected results.
11785 Conform to the GCS: simplify the locations when applicable.
11786 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
11787 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
11788 these CPP macros with the m4 macros new defined by...
11789 (AT_CHECK_PUSHDEFS): this, i.e.:
11790 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
11791 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
11792 New macros.
11793 (AT_CHECK_POPDEFS): Undefine them.
11794 (AT_CHECK_CALC_LALR1_CC): New.
11795 Use it for the first lalr1.cc test.
11796
11797 2003-02-04 Akim Demaille <akim@epita.fr>
11798
11799 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
11800 Location as is defined.
11801
11802 2003-02-04 Akim Demaille <akim@epita.fr>
11803
11804 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
11805 name_ being defined.
11806
11807 2003-02-03 Paul Eggert <eggert@twinsun.com>
11808
11809 * src/gram.h (start_symbol): Remove unused decl.
11810
11811 Use more-consistent naming conventions for local vars.
11812
11813 * src/derives.c (derives_compute): Change type of local var from
11814 int to rule_number.
11815 * src/gram.c (grammar_rules_partial_print): Likewise.
11816 * src/print.c (print_core): Likewise.
11817 * src/reduce.c (reduce_grammar_tables): Likewise.
11818
11819 * src/gram.c (grammar_dump): Change name of item_number *
11820 local var from r to rp.
11821 * src/nullable.c (nullable_compute): Likewise.
11822
11823 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.

11826 for symbol or symbol_number var.
11827 * src/reader.c (grammar_start_symbol_set): Likewise.
11828 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
11829 Likewise.

11834 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
11835 char * var.
11836
11837 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
11838 var.
11839
11840 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
11841 var.
11842
11843 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
11844 Use str, not s, for char * var. Use ch, not c, for character var.
11845 Use size for size var.
11846

11855 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
11856 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
11857 param to have same name as that of enum, so that we don't use
11858 "s" to stand for a non-state.
11859
11860 2003-02-02 Akim Demaille <akim@epita.fr>
11861
11862 * src/scan-skel.l: Scan more than one inert character per yylex
11863 invocation.
11864
11865 2003-02-01 Paul Eggert <eggert@twinsun.com>
11866
11867 Version 1.875a.
11868
11869 * po/LINGUAS: Add ms.
11870
11871 2003-01-30 Akim Demaille <akim@epita.fr>
11872
11873 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
11874
11875 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11876
11877 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
11878 of $1.
11879
11880 Changes in response to error report by S. Eken: GLR mode does not
11881 handle negative $ indices or $ indices in embedded rules correctly.
11882 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
11883
11884 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
11885 (b4_rhs_location): Ditto.
11886 (yyfill): New function to copy from stack tree into array
11887 incrementally.
11888 (yyuserAction): Modify to allow incremental move of semantic values
11889 to rhs array when in GLR mode.
11890 Define YYFILL to use in user-defined actions to fill semantic array
11891 as needed.
11892 Remove dummy use of yystack, as there is now a guaranteed use.
11893 (yydoAction): Modify to allow incremental move of semantic values
11894 to rhs array when in GLR mode.
11895 (yyresolveAction): Ditto.
11896 (yyglrShiftDefer): Update comment.
11897 (yyresolveStates): Use X == NULL for pointers, not !X.
11898 (yyglrReduce): Ditto.
11899 (yydoAction): Ditto
11900
11901 * tests/glr-regr1.at: Rename to ...
11902 * tests/glr-regression.at: Add new regression test for the problems
11903 described above (adapted from S. Eken).
11904 Update copyright notice.
11905 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
11906 * tests/Makefile.am: Ditto.
11907
11908 2003-01-28 Paul Eggert <eggert@twinsun.com>
11909
11910 * data/lalr1.cc: Do not use @output_header_name@ unless
11911 b4_defines_flag is set. This fixes two bugs reported by
11912 Tim Van Holder in
11913 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
11914 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
11915
11916 2003-01-21 Paul Eggert <eggert@twinsun.com>
11917
11918 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
11919 we don't need to worry about yyerrlab1 being reported as an
11920 "unused label" by non-GCC C compilers. The downside is that if
11921 locations are used then a couple of statements are duplicated each
11922 time YYERROR is invoked, but the upside is that the warnings
11923 should vanish.
11924 (yyerrlab1): Move code to YERROR.
11925 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11926 This reverts some of the 2002-12-27 change.
11927
11928 2003-01-17 Paul Eggert <eggert@twinsun.com>
11929
11930 * src/output.c (symbol_printers_output): Fix typo that led
11931 to core dump. Problem reported by Antonio Rus in
11932 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
11933
11934 2003-01-13 Akim Demaille <akim@epita.fr>,
11935 Quoc Peyrot <chojin@lrde.epita.fr>,
11936 Robert Anisko <anisko_r@lrde.epita.fr>
11937
11938 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
11939 when the stacks contain one element, as the loop would otherwise
11940 free the last state, and then use the top state (the one we just
11941 popped). This means that the initial elements will not be freed
11942 explicitly, as is the case in yacc.c; it is not a problem, as
11943 these elements have fake values.
11944
11945 2003-01-11 Paul Eggert <eggert@twinsun.com>
11946
11947 * NEWS: %expect-violations are now just warnings, reverting
11948 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
11949 bootstrapping problem reported by Matthias Klose; see
11950 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
11951 * src/conflicts.c (conflicts_print): Likewise.
11952 * tests/conflicts.at (%expect not enough, %expect too much,
11953 %expect with reduce conflicts): Likewise.
11954 * doc/bison.texinfo (Expect Decl): Document this. Also mention
11955 that the warning is enabled if the number of conflicts changes
11956 (not necessarily increases).
11957
11958 * src/getargs.c (version): Update copyright year.
11959
11960 2003-01-09 Akim Demaille <akim@epita.fr>
11961
11962 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
11963
11964 2003-01-08 Paul Eggert <eggert@twinsun.com>
11965
11966 * Makefile.maint (WGETFLAGS):
11967 New macro, containing "-C off" to disable proxy caches.
11968 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
11969 (rel-check): Use $(WGET) instead of wget.
11970
11971 2003-01-06 Paul Eggert <eggert@twinsun.com>
11972
11973 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
11974 the GLR paper of Scott, Johnstone and Hussain.
11975
11976 2003-01-04 Paul Eggert <eggert@twinsun.com>
11977
11978 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
11979 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
11980 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
11981 (EXTRA_LIBRARIES): New var, for liby.a.
11982 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
11983 (EXTRA_SCRIPTS): New var, for yacc.
11984
11985 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
11986 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
11987 Problem reported by Nelson H. F. Beebe.
11988
11989 2003-01-03 Paul Eggert <eggert@twinsun.com>
11990
11991 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
11992 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
11993 when compiling Bison 1.875's `bitset bset = obstack_alloc
11994 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
11995
11996 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
11997 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
11998 grow to a huge size with typical invocation.
11999
12000 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
12001 Use the pattern recommended by Autoconf 2.57, except also protect
12002 against double-definition.
12003 * src/system.h: Likewise.
12004 Portability issues reported by Nelson H. F. Beebe.
12005
12006 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
12007 All uses changed. Provide a definition in both C and C++.
12008 (yytrue, yyfalse): Define even if defined (__cplusplus).
12009
12010 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
12011 Reported by Nelson H. F. Beebe.
12012
12013 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
12014
12015 2003-01-02 Paul Eggert <eggert@twinsun.com>
12016
12017 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
12018 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
12019 Bug reported by Nelson H. F. Beebe.
12020
12021 2003-01-01 Paul Eggert <eggert@twinsun.com>
12022
12023 * Version 1.875.
12024
12025 2002-12-30 Paul Eggert <eggert@twinsun.com>
12026
12027 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
12028 Moved here from...
12029 (<INITIAL>","): Here. This causes stray "," to be treated
12030 more uniformly.
12031
12032 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
12033 last brace in braced code when not in Yacc mode, for compatibility
12034 with Bison 1.35. This resurrects the 2001-12-15 patch to
12035 src/reader.c.
12036
12037 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
12038 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
12039
12040 2002-12-28 Paul Eggert <eggert@twinsun.com>
12041
12042 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
12043 that of SYM's type. This fixes Debian bug 168069, reported by
12044 Thomas Olsson.
12045
12046 2002-12-28 Paul Eggert <eggert@twinsun.com>
12047
12048 Version 1.75f.
12049
12050 Switch back to the Yacc style of conflict reports, undoing some
12051 of the 2002-07-30 change.
12052 * doc/bison.texinfo (Understanding): Use Yacc style for
12053 conflict reports. Also, use new way of locating rules.
12054 * src/conflicts.c (conflict_report):
12055 Renamed from conflict_report_yacc, removing the old
12056 'conflict_report'. Translate the entire conflict report at once,
12057 so that we don't assume that "," has the same interpretation in
12058 all languages.
12059 (conflicts_output): Use Yacc-style conflict report for each state,
12060 instead of our more-complicated style.
12061 (conflicts_print): Use Yacc-style conflict report, except print
12062 the input file name when not emulating Yacc.
12063 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
12064 Conflicted Reduction, %expect not enough, %expect too much,
12065 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
12066 * tests/existing.at (GNU Cim Grammar): Likewise.
12067 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
12068
12069 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
12070 fatal): Don't invoke fflush; it's not needed and it might even be
12071 harmful for stdout, as stdout might not be open.
12072 * src/reduce.c (reduce_print): Likewise.
12073
12074 2002-12-27 Paul Eggert <eggert@twinsun.com>
12075
12076 Fix a bug where error locations were not being recorded correctly.
12077 This problem was originally reported by Paul Hilfinger in
12078 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
12079
12080 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12081 top of the location stack's error locations.
12082 (yyerrlab): Set it. When discarding a token, push its location
12083 onto yylerrsp so that we don't lose track of the error's end.
12084 (yyerrlab1): Now is only the target of YYERROR, so that we can
12085 properly record the location of the action that failed. For GCC
12086 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12087 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12088 (yyerrlab2): New label, which yyerrlab now falls through to.
12089 Compute the error's location by applying YYLLOC_DEFAULT to
12090 the locations of all the symbols that went into the error.
12091 * doc/bison.texinfo (Location Default Action): Mention that
12092 YYLLOC_DEFAULT is also invoked for syntax errors.
12093 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12094 Error locations include the locations of all the tokens that were
12095 discarded, not just the last token.
12096
12097 2002-12-26 Paul Eggert <eggert@twinsun.com>
12098
12099 * src/files.c: Include quote.h.
12100 (compute_output_file_names): Warn if we detect conflicting
12101 outputs to the same file. This should catch the misunderstanding
12102 exemplified by Debian Bug 165349, reported by Bruce Stephens..
12103
12104 * src/conflicts.c (conflicts_print): If the user specifies
12105 "%expect N", report an error if there are any reduce/reduce
12106 conflicts. This is what the manual says should happen.
12107 This fixes Debian bug 130890, reported by Anthony DeRobertis.
12108 * tests/conflicts.at (%expect with reduce conflicts): New test.
12109
12110 Don't use m4_include on relative file names, as it doesn't work as
12111 desired if there happens to be a file with that name under ".".
12112
12113 * m4sugar/version.m4: Remove; it was included but it wasn't used.
12114 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
12115 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
12116 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
12117 * src/output.c (output_skeleton): Use full path names when
12118 specifying a file to include; don't rely on include path, as
12119 it's unreliable when the working file contains a file with
12120 that name.
12121
12122 2002-12-25 Paul Eggert <eggert@twinsun.com>
12123
12124 Remove obsolete references to bison.simple and bison.hairy.
12125 Problem mentioned by Aubin Mahe in
12126 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
12127 * data/glr.c: Comment fix.
12128 * doc/bison.1: Remove references. Also, mention "yacc".
12129
12130 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
12131 with -g option.
12132
12133 * src/parse-gram.y (declaration): Use enum "report_states" rather
12134 than its numeric value 1.
12135
12136 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
12137 opening a new one. This fixes Debian bug 165349, reported by
12138 Bruce Stephens.
12139
12140 2002-12-24 Paul Eggert <eggert@twinsun.com>
12141
12142 Version 1.75e.
12143
12144 * Makefile.maint (cvs-update): Don't assume that the shell
12145 supports $(...), as Solaris sh doesn't.
12146
12147 * src/parse-gram.y (lloc_default): Remove test for empty
12148 nonterminals at the end, since it didn't change the result.
12149
12150 2002-12-24 Paul Eggert <eggert@twinsun.com>
12151
12152 If the user does not define YYSTYPE as a macro, Bison now declares it
12153 using typedef instead of defining it as a macro. POSIX requires this.
12154 For consistency, YYLTYPE is also declared instead of defined.
12155
12156 %union directives can now have a tag before the `{', e.g., the
12157 directive `%union foo {...}' now generates the C code
12158 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12159 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12160 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12161 instead of `yyltype'.
12162
12163 `yystype' and `yyltype' are now obsolescent macros instead of being
12164 typedefs or tags; they are no longer documented and will be
12165 withdrawn in a future release.
12166
12167 * data/glr.c (b4_location_type): Remove.
12168 (YYSTYPE): Renamed from yystype.
12169 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
12170 (struct YYLTYPE): Renamed from struct yyltype.
12171 (YYLTYPE): Renamed from yyltype.
12172 (yyltype, yystype): New (and obsolescent) macros,
12173 for backward compatibility.
12174 * data/yacc.c: Likewise.
12175
12176 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12177 does not specify a union tag. This is for compatibility with
12178 Solaris 9 yacc.
12179
12180 * src/parse-gram.y (add_param): 2nd arg is now char * not char
12181 const *, since it is now modified by stripping surrounding { }.
12182 (current_braced_code): Remove.
12183 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
12184 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
12185 trailing " {...}". Now of type <chars>.
12186 (grammar_declaration): Adjust to bundled tokens.
12187 (code_content): Remove; stripping is now done by add_param.
12188 (print_token_value): Print contents of bundled tokens.
12189 (token_name): New function.
12190
12191 * src/reader.h (braced_code, current_braced_code): Remove.
12192 (token_name): New decl.
12193
12194 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
12195 token_type, not braced_code code_kind. All uses changed.
12196 (SC_PRE_CODE): New state, for scanning after a keyword that
12197 has (or usually has) an immediately-following braced code.
12198 (token_type): New local var, to keep track of which token type
12199 to return when scanning braced code.
12200 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
12201 <INITIAL>"%parse-param", <INITIAL>"%printer",
12202 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
12203 instead of returning a token type immediately.
12204 (<INITIAL>"{"): Set token type.
12205 (<SC_BRACED_CODE>"}"): Use it.
12206 (handle_action_dollar, handle_action_at): Now returns bool
12207 indicating success. Fail if ! current_rule; this prevents a core dump.
12208 (handle_symbol_code_dollar, handle_symbol_code_at):
12209 Remove; merge body into caller.
12210 (handle_dollar, handle_at): Complain in invalid contexts.
12211
12212 * NEWS, doc/bison.texinfo: Document the above.
12213 * NEWS: Fix years and program names in copyright notice.
12214
12215 2002-12-17 Paul Eggert <eggert@twinsun.com>
12216
12217 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
12218 Reporting, Table of Symbols): Omit mentions of %lex-param and
12219 %parse-param from the documentation for now.
12220
12221 2002-12-15 Paul Eggert <eggert@twinsun.com>
12222
12223 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
12224 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
12225 lookahead symbol, and which sets yychar in parser actions) and it
12226 disagreed with the Bison documentation. Bug
12227 reported by Andrew Walrond.
12228
12229 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12230 as the caller now does that.
12231 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12232 (YYEMPTY): Parenthesize right hand side, since others use it.
12233 (yyparse): Don't assume that our generated code is the only code
12234 that sets yychar.
12235
12236 2002-12-13 Paul Eggert <eggert@twinsun.com>
12237
12238 Version 1.75d.
12239
12240 POSIX requires a "yacc" command.
12241 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
12242 (MOSTLYCLEANFILES): Add yacc.
12243 (yacc): New rule.
12244 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
12245 as an alias for bison y.
12246
12247 * po/LINGUAS: Add da.
12248
12249 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
12250 problem with latest <getopt.h>.
12251 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
12252
12253 * doc/fdl.texi: Upgrade to 1.2.
12254 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
12255 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
12256 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
12257 gnulib.
12258 * config/install-sh: Sync with autotools.
12259
12260 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
12261 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12262 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
12263 locations are requested.
12264 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
12265 locations are requested.
12266
12267 2002-12-12 Paul Eggert <eggert@twinsun.com>
12268
12269 Remove unportable casts and storage allocation tricks.
12270 While we're at it, remove almost all casts, since they
12271 usually aren't needed and are a sign of trouble.
12272
12273 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12274
12275 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12276 the pointer DSET returned by malloc; this isn't portable.
12277 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12278 Similarly for DERIVES.
12279 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12280 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
12281 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
12282
12283 * src/derives.c (derives_compute): Do not bother invoking
12284 int_of_rule_number, since rule numbers are integers.
12285
12286 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
12287 rather than XMALLOC (char, N).
12288
12289 * src/files.c (filename_split): Rewrite to avoid cast.
12290
12291 * src/gram.h (symbol_number_as_item_number,
12292 item_number_as_symbol_number, rule_number_as_item_number,
12293 item_number_as_rule_number):
12294 Now inline functions rather than macros, to avoid casts.
12295 * src/state.h (state_number_as_int): Likewise.
12296 * src/tables.c (state_number_to_vector_number,
12297 symbol_number_to_vector_number): Likewise.
12298
12299 * src/gram.h (int_of_rule_number): Remove; no longer used.
12300
12301 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
12302 since the resulting storage is always stored into.
12303
12304 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12305 where it's needed.
12306
12307 * src/muscle_tab.c (muscle_m4_output):
12308 Now inline. Return bool, not int.
12309 * src/state.c (state_compare): Likewise.
12310 * src/symtab.c (symbol_check_defined,
12311 symbol_check_alias_consistency, symbol_pack, symbol_translation,
12312 hash_compare_symbol, hash_symbol):
12313 Likewise.
12314 * src/uniqstr.c (uniqstr_print): Likewise.
12315 * src/muscle_tab.c (muscle_m4_output_processor):
12316 New function, to avoid casts.
12317 * src/state.c (state_comparator, stage_hasher): Likewise.
12318 * src/symtab.c (symbol_check_defined_processor,
12319 symbol_check_alias_consistency_processor, symbol_pack_processor,
12320 symbol_translation_processor, hash_symbol_comparator,
12321 hash_symbol_hasher): Likewise.
12322 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12323 * src/muscle_tab.c (muscles_m4_output):
12324 Use new functions instead of casting old functions unportably.
12325 * src/state.c (state_hash_new): Likewise.
12326 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12327 symbols_token_translations_init):
12328 Likewise.
12329 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12330
12331 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12332 var instead of casting to long, to avoid casts.
12333 (prepare_states): Use MALLOC rather than alloca, so that we don't
12334 have to worry about alloca.
12335 * src/state.c (state_hash_lookup): Likewise.
12336
12337 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12338 local var instead of casting to unsigned char, to avoid casts.
12339
12340 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12341 STATE_ALLOC): Remove.
12342 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12343 rather than calloc, and use offsetof to avoid allocating slightly
12344 too much storage.
12345 (state_new): Initialize all members.
12346
12347 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12348
12349 * src/symtab.c (symbol_free): Remove; unused.
12350 (symbol_get): Remove cast in lhs of assignment.
12351 (symbols_do): Now static. Accept generic arguments, not
12352 hashing-related ones.
12353
12354 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12355 (symbol_processor): Remove.
12356 (symbols_do): Remove decl; now static.
12357
12358 * src/system.h (alloca): Remove; decl no longer needed.
12359 (<stddef.h>): Include, for offsetof.
12360 (<inttypes.>, <stdint.h>): Include if available.
12361 (uintptr_t): New type, if system lacks it.
12362 (CALLOC, MALLOC, REALLOC): New macros.
12363 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
12364 new macros.
12365
12366 * src/tables.c (table_size): Now int, to pacify GCC.
12367 (table_grow, table_ninf_remap): Use signed table size.
12368 (save_row): Don't bother initializing locals when not needed.
12369 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
12370 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
12371
12372 * src/vcg.h: Correct misspellings.
12373
12374 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
12375
12376
12377 * src/getargs.c (getargs): Don't assume EOF == -1.
12378
12379 2002-12-09 Paul Eggert <eggert@twinsun.com>
12380
12381 Change identifier spellings to avoid collisions with names
12382 that are reserved by POSIX.
12383
12384 Don't use names ending in _t, since POSIX reserves them.
12385 For consistency, remove _e and _s endings -- they're weren't
12386 needed to remove ambiguity. All uses changed.
12387 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12388 turn was just renamed from struniq_t.
12389 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12390 which in turn was just renamed from struniq_processor_t.
12391 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
12392 in turn was renamed from hash_compare_struniq_t.

12405 (rule): Renamed from rule_t.
12406 (rule_filter): Renamed from rule_filter_t.
12407 * src/lalr.c (struct goto_list): Renamed from struct goto_list_s.

12409 * src/lalr.h (goto_number): Renamed from goto_number_t.
12410 * src/location.h (location): Renamed from location_t.
12411 * src/muscle_tab.c (muscle_entry): Renamed from muscle_entry_t,

12415 (rule_list): Renamed from rule_list_t.
12416 * src/print_graph.c (static_graph): Renamed from graph.

12421 (relation): Renamed from relation_t.
12422 * src/state.h (state_number): Renamed from state_number_t.
12423 (struct state): Renamed from struct state_s.
12424 (state): Renamed from state_t.
12425 (transitions): Renamed from transitions_t. Unused (and
12426 misspelled) transtion_s tag removed.
12427 (errs): Renamed from errs_t. Unused errs_s tag removed.
12428 (reductions): Renamed from reductions_t. Unused tag
12429 reductions_s removed.
12430 * src/symlist.h (symbol_list): Renamed from symbol_list_t.

12461 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
12462 value_t_as_yystype -> value_as_yystype.
12463
12464 Don't include <errno.h> in the mainstream code, since it
12465 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
12466 * lib/get-errno.c, lib/get-errno.h: New files.
12467 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
12468 get-errno.c.
12469 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
12470 * src/output.c (output_skeleton): Likewise.
12471 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
12472 instead of errno.
12473 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>\\x[0-9abcdefABCDEF]+):
12474 Likewise.
12475 (handle_action_dollar, handle_action_at): Likewise.
12476 * src/system.h: Do not include <errno.h>.
12477 (TAB_EXT): Renamed from EXT_TAB.
12478 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
12479
12480 Avoid str[a-z]*, since <string.h> reserves that name space.
12481 Change all instances of "struniq" in names to "uniqstr", and
12482 likewise for "STRUNIQ" and "UNIQSTR".
12483 * src/uniqstr.c: Renamed from src/struniq.c.
12484 * src/uniqstr.h: Renamed from src/struniq.h.
12485 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

12496 (N_EXPAND): Renamed from N_STRETCH.
12497
12498 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
12499 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
12500 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

12508 (ACTION_MAX): Remove; unused.
12509 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
12510 Unnecessary casts removed from above defines.
12511
12512
12513 Fix misspelling in names.

12515 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
12516 G_NODE_ALIGNEMENT.
12517
12518
12519 * lib/timevar.c (timevar_report): Renamed from time_report,
12520 for consistency with other names.
12521 * lib/timevar.h (timevar_report): New decl.
12522 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
12523
12524
12525 Sort include-file uses.
12526
12527 Reorder all include files under src to be in the order "system.h".
12528 then the ../lib include files in angle brackets (alphabetized),
12529 then the . include files in double-quotes (alphabetized). Fix
12530 dependency breakages encountered in this process, as follows:
12531 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
12532 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
12533 * src/state.h: Include "symtab.h".
12534
12535 2002-12-08 Paul Eggert <eggert@twinsun.com>
12536
12537 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
12538 since this causes problems when __file__ contains character
12539 sequences like "@" that are treated specially by src/scan-skel.l.
12540 Instead, just use the file's basename. This fixes the bug
12541 reported by Martin Mokrejs in
12542 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
12543
12544 2002-12-06 Paul Eggert <eggert@twinsun.com>
12545
12546 Add support for rules that do not have trailing semicolons, as
12547 POSIX requires. Improve the quality of locations in Bison
12548 diagnostics.
12549
12550 * src/location.c: Include <quotearg.h>.
12551 (empty_location): Now const.
12552 (location_print): New function. Follow the recommendation of the
12553 GNU Coding Standards for locations that span file boundaries.
12554 * src/location.h: Do not include <quotearg.h>; no longer needed.
12555 (boundary): New type.
12556 (location_t): Use it. This allows locations to span file boundaries.
12557 All member uses changed: file -> start.file or end.file (as needed),
12558 first_line -> start.line, first_column -> start.column,
12559 last_line -> end.line, last_column -> end.column.
12560 (equal_boundaries): New function.
12561 (LOCATION_RESET, LOCATION_STEP): Remove.
12562 (LOCATION_PRINT): Remove. All callers changed to use location_print.
12563 (empty_location): Now const.
12564 (location_print): New decl.
12565 * src/parse-gram.y (lloc_default): New function, which handles
12566 empty locations more accurately.
12567 (YYLLOC_DEFAULT): Use it.
12568 (%token COLON): Remove.
12569 (%token ID_COLON): New token.
12570 (rules): Use it.
12571 (declarations, rules): Remove trailing semicolon.
12572 (declaration, rules_or_grammar_declaration):
12573 Allow empty (";") declaration.
12574 (symbol_def): Remove empty actions; no longer needed.
12575 (rules_or_grammar_declaration): Remove trailing semicolon.
12576 (semi_colon.opt): Remove.
12577 * src/reader.h: Include location.h.
12578 (scanner_cursor): New decl.
12579 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
12580 rolling our own.
12581 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
12582 of *loc.
12583 (STEP): Remove. No longer needed, now that adjust_location does
12584 the work. All uses removed.
12585 (scanner_cursor): New var.
12586 (adjust_location): Renamed from extend_location. It now sets
12587 *loc and adjusts the scanner cursor. All uses changed.
12588 Don't bother testing for CR.
12589 (handle_syncline): Remove location arg; now updates scanner cursor.
12590 All callers changed.
12591 (unexpected_end_of_file): Now accepts start boundary of token or
12592 comment, not location. All callers changed. Update scanner cursor,
12593 not the location.
12594 (SC_AFTER_IDENTIFIER): New state.
12595 (context_state): Renamed from c_context. All uses changed.
12596 (id_loc, code_start, token_start): New local vars.
12597 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
12598 processing of Yacc white space and equivalents here.
12599 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
12600 instead of returning ID immediately, since we need to search for
12601 a subsequent colon.
12602 (<INITIAL>"'", "\""): Save token_start.
12603 (<INITIAL>"%{", "{", "%%"): Save code_start.
12604 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
12605 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
12606 BEGIN context_state at end, not INITIAL.
12607 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
12608 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
12609 Return correct token start.
12610 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
12611 the start of a character, string or multiline comment is found.
12612 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
12613 Reduction): Adjust reported locations to match the more-precise
12614 results now expected.
12615 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
12616 * tests/reduce.at (Useless Rules, Reduced Automaton,
12617 Underivable Rules): Likewise.
12618 * tests/regression.at (Invalid inputs): No longer `expecting ";"
12619 or "|"' now that so many other tokens are allowed by the new grammar.
12620
12621 * src/complain.h (current_file): Remove duplicate decl;
12622 current_file is now owned by files.h.
12623 * src/complain.c, src/scan-gram.l: Include files.h.
12624
12625 2002-12-06 Paul Eggert <eggert@twinsun.com>
12626
12627 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
12628 promotes to int; it might be unsigned int.
12629 * data/yacc.c (yy_reduce_print): Likewise.
12630
12631 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
12632 be #defined in the prologue, not in the Bison declarations.
12633 This fixes Debian Bug 102878, reported by Shaul Karl.
12634
12635 2002-12-02 Paul Eggert <eggert@twinsun.com>
12636
12637 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
12638 * lib/strtoul.c: New file, from gnulib.
12639 This fixes a porting bug reported by Peter Klein in
12640 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
12641
12642 2002-11-30 Paul Eggert <eggert@twinsun.com>
12643
12644 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
12645 and put only a forward declaration in the prologue. This is for
12646 consistency with the other scanner helper functions.
12647
12648 Type clashes now generate warnings, not errors, since it
12649 appears that POSIX may allow some grammars with type clashes.
12650 * src/reader.c (grammar_current_rule_check): Warn about
12651 type clashes instead of complaining.
12652 * tests/input.at (Type Clashes): Expect warnings, not complaints.
12653
12654 Add Yacc library, since POSIX requires it.
12655 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
12656 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
12657 * lib/main.c, lib/yyerror.c: New files.
12658
12659 gram_error can be static; it need not be extern.
12660 * src/reader.h (gram_error): Remove decl.
12661 * src/parse-gram.y (gram_error): Now static. Add static decl.
12662 (print_token_value): Omit parameter names from forward decl,
12663 for consistency.
12664
12665 2002-11-29 Paul Eggert <eggert@twinsun.com>
12666
12667 * doc/bison.texinfo: Emphasize that yylex and yyerror must
12668 be declared before being used. E.g., one should typically
12669 declare them in the prologue. Use GNU coding style in examples.
12670 Put "const" consistently after the type it modifies. Mention
12671 that C99 supports "inline". Mention that yyerror traditionally
12672 returns "int".
12673
12674 %parse-param and %lex-param now take just one argument, the
12675 declaration; the argument name is deduced from the declaration.
12676
12677 * doc/bison.texinfo (Parser Function, Pure Calling, Error
12678 Reporting, Table of Symbols): Document this.
12679 * src/parse-gram.y (add_param): New function.
12680 (COMMA): Remove.
12681 (declaration): Implement new rule for %parse-param and %lex-param.
12682 * src/scan-gram.l: "," now elicits a warning, rather than being
12683 a token; this is more compatible with byacc.
12684 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
12685
12686 2002-11-27 Paul Eggert <eggert@twinsun.com>
12687
12688 Rename identifiers to avoid real and potential collisions.
12689
12690 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
12691 to avoid collision with lex macro described by Bruce Lilly in
12692 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12693 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
12694 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
12695 * src/parse-gram.y (print_token_value): Renamed from yyprint.
12696 All uses changed.
12697 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
12698 The name "yycontrol" violates the name space rules, and this stuff
12699 wasn't being used anyway.
12700 (input): Remove action; this stuff wasn't being used.
12701 (gram_error): Rename local variable yylloc -> loc.
12702 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
12703 (YY_DECL): Don't use "yy" at start of local variables.
12704 All uses changed, e.g., yylloc -> loc.
12705 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
12706 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
12707 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
12708 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
12709
12710 * src/parse-gram.y (gram_error): loc is now const *.
12711 * src/reader.h (gram_error): Likewise.
12712
12713 2002-11-24 Paul Eggert <eggert@twinsun.com>
12714
12715 Version 1.75c.
12716
12717 * tests/actions.at (Actions after errors): Use an output format
12718 more similar to that of the Printers and Destructors test.
12719 Test the position of the ';' token too.
12720 (Printers and Destructors): Likewise.
12721 (Printers and Destructors: %glr-parser): Remove for now, to avoid
12722 unnecessarily alarming people when the test fails.
12723
12724 * data/yacc.c (yyerrlab1): Move this label down, so that the
12725 parser does not discard the lookahead token if the user code
12726 invokes YYERROR. This change is required for POSIX conformance.
12727
12728 * lib/error.c: Sync with gnulib.
12729
12730 2002-11-22 Paul Eggert <eggert@twinsun.com>
12731
12732 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
12733 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
12734 * lib/xmalloc.c: Likewise.
12735
12736 2002-11-20 Paul Eggert <eggert@twinsun.com>
12737
12738 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
12739
12740 2002-11-20 Paul Eggert <eggert@twinsun.com>
12741
12742 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
12743 should use `if (! x) abort ();' rather than `assert (x);', and
12744 anyway it's one less thing to worry about configuring.
12745
12746 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
12747 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
12748 and replace all instances of assert with abort.
12749 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
12750 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
12751
12752 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
12753 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
12754 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
12755 hash_find_entry, hash_rehash, hash_insert): Likewise.
12756 * src/conflicts.c (resolve_sr_conflict): Likewise.
12757 * src/lalr.c (set_goto_map, map_goto): Likewise.
12758 * src/nullable.c (nullable_compute): Likewise.
12759 * src/output.c (prepare_rules, token_definitions_output): Likewise.
12760 * src/reader.c (packgram, reader): Likewise.
12761 * src/state.c (state_new, state_free, state_transitions_set,
12762 state_reduction_find): Likewise.
12763 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
12764 symbol_pack): Likewise.
12765 * src/tables.c (conflict_row, pack_vector): Likewise.
12766 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12767 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12768 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
12769 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
12770
12771 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
12772 (ARGMATCH_CONSTRAINT): New macro.
12773 (ARGMATCH_ASSERT): Use it.
12774
12775 * src/system.h (verify): New macro.
12776 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
12777 rather than assert.
12778 * src/tables.c (tables_generate): Likewise.
12779
12780 * src/struniq.c (struniq_assert): Now returns void, and aborts
12781 if the assertion is false.
12782 (struniq_assert_p): Remove.
12783 * src/struniq.h: Likewise.
12784
12785 2002-11-18 Paul Eggert <eggert@twinsun.com>
12786
12787 * data/glr.c (yygetLRActions): Replace `yyindex' with
12788 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
12789 This fixes the regression with Sun ONE Studio 7 cc that I reported in
12790 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
12791
12792 2002-11-18 Akim Demaille <akim@epita.fr>
12793
12794 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
12795 space.
12796 From Tim Van Holder.
12797
12798 2002-11-17 Paul Eggert <eggert@twinsun.com>
12799
12800 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
12801 to "SyntaxError" for consistency with my 2002-11-15 change.
12802
12803 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
12804 not define to {}, since this breaks the common use of `YYDPRINTF
12805 ((...));' if a single statement is desired (e.g. before `else').
12806 Work around GCC warnings by surrounding corresponding calls with
12807 {} if needed.
12808 (yyhasResolvedValue): Remove unused function.
12809 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
12810 loop body.
12811 (yyreportSyntaxError): Renamed from yyreportParseError.
12812 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
12813 All uses changed.
12814 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
12815 extern when possible. Remove unused initializations.
12816
12817 2002-11-16 Akim Demaille <akim@epita.fr>
12818
12819 Augment the similarity between GLR and LALR traces.
12820
12821 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
12822 (YY_REDUCE_PRINT): New.
12823 (yyparse): Use them.
12824 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
12825 YYDPRINT here.
12826 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
12827 state reached after the reduction/recovery, since...
12828 (yyparse, yyprocessOneStack): Report the state we are entering in.
12829
12830 2002-11-16 Akim Demaille <akim@epita.fr>
12831
12832 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
12833 Add support for --trace=skeleton.
12834 * src/scan-skel.l: %option debug.
12835 Scan strings of non-@ or \n instead of character by character.
12836 (scan_skel): Handle trace_skeleton.
12837 (QPUTS): New.
12838 (@output_parser_name@, @output_header_name@): ``Restore'' their
12839 support (used to be M4 macros).
12840 * data/yacc.c: Quote larger chunks, a la glr.c.
12841 * data/lalr1.cc: Likewise.
12842 The header guards are no longer available, so use some other
12843 string than `YYLSP_NEEDED'.
12844
12845 2002-11-16 Akim Demaille <akim@epita.fr>
12846
12847 Make the ``Printers and Destructors'' test more verbose, taking
12848 `yacc.c''s behavior as (possibly wrong) reference.
12849
12850 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
12851 instead of fprint on stdout.
12852 Set and report the last_line of the symbols.
12853 Consistently display values and locations.
12854
12855 2002-11-16 Paul Eggert <eggert@twinsun.com>
12856
12857 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
12858
12859 2002-11-15 Paul Eggert <eggert@twinsun.com>
12860
12861 * tests/actions.at (Actions after errors): New test case.
12862
12863 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
12864 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
12865 tests/action.at, tests/calc.at, tests/conflicts.at,
12866 tests/cxx-type.at, tests/regression.at:
12867 "parse error" -> "syntax error" for POSIX compatibility.
12868 "parsing stack overflow..." -> "parser stack overflow" so
12869 that code matches Bison documentation.
12870
12871 2002-11-15 Akim Demaille <akim@epita.fr>
12872
12873 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
12874 take two BRACED_CODE, not two string_content.
12875 Free the scanner's obstack when we are done.
12876 (code_content): New.
12877 * tests/calc.at: Adjust.
12878 * doc/bison.texinfo: Adjust.
12879 Also, make sure to include the `,' for these declarations.
12880
12881 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
12882
12883 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
12884 definition; avoids potential autoreconf problems.
12885
12886 2002-11-15 Akim Demaille <akim@epita.fr>
12887
12888 Always check the value returned by yyparse.
12889
12890 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
12891 returned by yyparse.
12892 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
12893 Adjust calls.
12894 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
12895 returned by yyparse.
12896
12897 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12898
12899 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
12900 on input.at test.
12901
12902 2002-11-14 Paul Eggert <eggert@twinsun.com>
12903
12904 * src/output.c (output_skeleton): Call xfopen instead of
12905 duplicating xfopen's body.
12906
12907 Fix bugs reported by Nelson H. F. Beebe in
12908 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
12909
12910 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
12911 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
12912 Group compiler. Instead, use "$CC -E bar.c". Include the .h
12913 file twice in the grammar, as an extra check.
12914
12915 * tests/input.at (Torturing the Scanner): Surround the
12916 backslash-newline tests with "#if 0", to make it less likely that
12917 we'll run into compiler bugs. Bring back solitary \ inside
12918 comment, but add a closing comment to work around HP C bug. Don't
12919 test backslash-newline in C character constant.
12920
12921 2002-11-14 Akim Demaille <akim@epita.fr>
12922
12923 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
12924 status of the compiler.
12925 Calling `exit 1' is no longer needed.
12926 Reported by Nelson H. F. Beebe.
12927
12928 2002-11-14 Akim Demaille <akim@epita.fr>
12929
12930 * tests/atlocal.in (CPPFLAGS): We have config.h.
12931 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
12932 New.
12933 * tests/actions.at, tests/calc.at, tests/conflicts.at,
12934 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
12935 * tests/regression.at, tests/torture.at: Use them for all the
12936 grammars that are to be compiled.
12937 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
12938 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
12939 * doc/bison.texinfo (GLR Parsers): Document `inline'.
12940
12941 2002-11-14 Akim Demaille <akim@epita.fr>
12942
12943 * doc/bison.texinfo: Various formatting changes (alignments in
12944 samples, additional @group/@end group, GCS in samples.
12945 Use @deffn instead of simple @table to define the directives,
12946 macros, variables etc.
12947
12948 2002-11-13 Paul Eggert <eggert@twinsun.com>
12949
12950 Fix some bugs reported by Albert Chin-A-Young in
12951 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
12952
12953 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
12954 -o c"; the HP C compiler chatters during compilation.
12955 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
12956 * tests/headers.at (export YYLTYPE): Likewise.
12957
12958 * tests/input.at (Torturing the Scanner): Remove lines containing
12959 solitary backslashes, as they tickle a bug in the HP C compiler.
12960
12961 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
12962 comments, since they're not portable. Use GNU coding style.
12963
12964 2002-11-13 Akim Demaille <akim@epita.fr>
12965
12966 * data/yacc.c: Leave bigger chunks of quoted text.
12967 (YYDSYMPRINTF): New.
12968 Use it to report symbol activities.

12970 Use it.
12971
12972 2002-11-12 Paul Eggert <eggert@twinsun.com>
12973
12974 Version 1.75b.
12975
12976 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
12977 (yyglrReduce): Return yyok, not 0.
12978 This should avoid the enumerated-type warnings reported
12979 by Nelson H. F. Beebe in
12980 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
12981
12982 * lib/bbitset.h (BITSET_INLINE): Remove.
12983 * lib/bitset.h [! BITSET_INLINE]: Remove.
12984 (bitset_set, bitset_reset, bitset_test): Rename local vars
12985 to avoid shadowing warnings by GCC.
12986
12987 * data/glr.c (inline): Remove #define. It's the user's
12988 responsibility to #define it away, just like 'const'.
12989 This fixes one of the bugs reported by Nelson H. F. Beebe in
12990 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
12991
12992 * Makefile.maint (po-check): Scan .l and .y files instead of the
12993 .c and the .h files that they generate. This fixes the bug
12994 reported by Tim Van Holder in:
12995 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
12996 Look for N_ as well as for _. Try to avoid matching #define for
12997 N_ and _.
12998 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
12999 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
13000 * src/scan-gram.l: Revamp regular expressions so that " and '
13001 do not confuse xgettext.
13002
13003 * src/struniq.h (struniq_new): Do not declare the return type
13004 to be 'const'; this violates the C standard.
13005 * src/struniq.c (struniq_new): Likewise.
13006
13007 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
13008
13009 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
13010 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
13011 linker.
13012
13013 2002-11-12 Akim Demaille <akim@epita.fr>
13014
13015 * Makefile.maint: Sync with Autoconf:
13016 (local_updates): New.
13017
13018 2002-11-12 Akim Demaille <akim@epita.fr>
13019
13020 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
13021
13022 2002-11-12 Akim Demaille <akim@epita.fr>
13023
13024 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
13025 locations.
13026
13027 2002-11-12 Akim Demaille <akim@epita.fr>
13028
13029 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
13030 not yyvalue.
13031
13032 2002-11-12 Akim Demaille <akim@epita.fr>
13033
13034 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
13035 Use it to test the GLR parser.

13037 2002-11-12 Akim Demaille <akim@epita.fr>
13038
13039 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
13040 defines it.
13041 * data/glr.c (yystos): New.
13042 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
13043 (YYDSYMPRINT): New.
13044 (yyval): Don't define it, it is handled via M4.
13045 (yyrecoverParseError): Free verbosely the discarded symbols.
13046 * data/yacc.c (yysymprint): Remove, rather...
13047 (b4_yysymprint_generate): invoke.
13048 * data/c.m4 (b4_yysymprint_generate): New.
13049 Accept pointers as arguments, as opposed to the version from
13050 yacc.c.
13051 (b4_yydestruct_generate): Likewise.
13052 * tests/cations.at (Printers and Destructors): Use Bison directives
13053 instead of CPP macros.
13054 Don't rely on internal details.
13055
13056 2002-11-12 Akim Demaille <akim@epita.fr>
13057
13058 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
13059 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
13060 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
13061 it against YYEMPTY and so forth), work on yytoken (i.e., set
13062 it to YYEMPTY etc.).
13063 (yydestruct): Replace with a b4_yydestruct_generate invocation.
13064 (b4_symbol_actions): Remove.
13065 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
13066 for 0, end-of-input.
13067
13068 2002-11-12 Akim Demaille <akim@epita.fr>
13069
13070 * doc/bison.texinfo (Destructor Decl): New.
13071
13072 2002-11-12 Akim Demaille <akim@epita.fr>
13073
13074 * src/tables.c (tables_generate): Use free for pointers that
13075 cannot be NULL, not XFREE.
13076 (pack_vector): Use assert, not fatal, for bound violations.
13077 * src/state.c (state_new): Likewise.
13078 * src/reader.c (reader): Likewise.
13079 * src/lalr.c (set_goto_map): Likewise.
13080 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
13081 the file name.
13082
13083 2002-11-12 Akim Demaille <akim@epita.fr>
13084
13085 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
13086 Restore.
13087 * src/scan-gram.l (last_string): Is global to the file, not to
13088 yylex.
13089 * src/parse-gram.y (input): Don't append the epilogue here,
13090 (epilogue.opt): do it here, and free the scanner's obstack.
13091 * src/reader.c (epilogue_set): Rename as...
13092 (epilogue_augment): this.
13093 * data/c.m4 (b4_epilogue): Defaults to empty.
13094
13095 2002-11-12 Akim Demaille <akim@epita.fr>
13096

13102
13103 2002-11-12 Akim Demaille <akim@epita.fr>
13104
13105 * src/struniq.h, src/struniq.c (struniq_t): Is const.
13106 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
13107
13108 Use struniq for symbols.
13109
13110 * src/symtab.h (symbol_t): The tag member is a struniq.
13111 (symbol_type_set): Adjust.

13151 2002-11-11 Paul Eggert <eggert@twinsun.com>
13152
13153 Revamp to fix many (but not all) of the C- and M4-related quoting
13154 problems. Among other things, this fixes the Bison bug reported
13155 by Jan Hubicka when processing the Bash grammar; see:
13156 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
13157
13158 Use new @ escapes consistently. Represent brackets with @{ and @}
13159 rather than @<:@ and @:>@, since this works a bit better with dumb
13160 editors like vi. Represent @ with @@, since @ is now consistently
13161 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13162 __ofile__, to avoid unexpected expansions. Similarly, use @output
13163 rather than #output.
13164
13165 * data/c.m4 (b4_copyright): Omit file name from comment, since
13166 the file name could contain "*/".
13167 (b4_synclines_flag): Don't quote the 2nd argument; it should already
13168 be quoted. All uses changed.
13169
13170 * data/glr.c: Use new @ escapes consistently.
13171 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
13172 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
13173 Remove, since they couldn't handle arbitrary characters in file
13174 names.
13175 * data/lalr1.cc: Likewise.
13176 * data/yacc.c: Likewise.
13177
13178 * src/files.c (output_infix): Remove; all uses removed.
13179 * src/files.h: Likewise.
13180
13181 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
13182 mishandled funny characters in file names, and anyway it isn't
13183 needed any more.
13184 * data/yacc.c: Likewise.
13185 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
13186
13187 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
13188 * data/yacc.c: Likewise.
13189
13190 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
13191 strings now.
13192 (muscle_init): Quote filename as a C string.
13193 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
13194 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
13195 * src/output.c (escaped_file_name_output): New function.
13196 (prepare_symbols): Quote tokens for M4.
13197 (prepare): Don't insert output_infix, output_prefix,
13198 output_parser_name, output_header_name; this is now down by scan-skel.
13199 Insert skeleton as a C string.
13200
13201 * src/output.c (user_actions_output, symbol_destructors_output,
13202 symbol_printers_output): Quote filenames for C and M4.
13203 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13204
13205 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
13206 escapes other than \\ and \'; this simplifies the code.
13207 (<SC_STRING>): Likewise, for \\ and \".
13208 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13209 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13210 Use new escapes @{ and @} for [ and ].
13211
13212 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13213 them with auto vars.
13214 Switch to new escape scheme, where @ is the escape character uniformly.
13215 Abort if a stray escape character is found. Avoid unbounded input
13216 buffer when parsing non-escaped text.
13217
13218 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
13219 __oline__, #output, $@, and @{ do not have unintended meanings.
13220
13221 2002-11-09 Paul Eggert <eggert@twinsun.com>
13222
13223 Fix the test failure due to GCC warnings described in
13224 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
13225 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
13226 evaluate to 0 if it's impossible for NINF to be in the respective
13227 table.
13228 (yygetLRActions, yyrecoverParseError): Use them.
13229
13230 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13231 counted in the token inserted at end of file. Now takes
13232 location_t *, not location_t, so that the location can be
13233 adjusted. All uses changed.
13234
13235 * tests/regression.at (Invalid inputs): Adjust wording in
13236 diagnostic to match the new behavior.
13237
13238 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13239 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13240 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13241 abort ();'. This reduces the runtime of the "Many lookaheads"
13242 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13243 GCC 3.2.
13244
13245 2002-11-07 Paul Eggert <eggert@twinsun.com>
13246
13247 * src/parse-gram.y (CHARACTER): Remove unused token.
13248 All uses removed.
13249
13250 * src/scan-gram.l: Remove stack option. We no longer use the
13251 stack, since the stack was never deeper than 1; instead, use the
13252 new auto var c_context to record the stacked value.
13253
13254 Remove nounput option. At an unexpected end of file, we now unput
13255 the minimal input necessary to end cleanly; this simplifies the
13256 code.
13257
13258 Avoid unbounded token sizes where this is easy.
13259
13260 (unexpected_end_of_file): New function.
13261 Use it to systematize the error message on unexpected EOF.
13262 (last-string): Now auto, not static.
13263 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
13264 (scanner_last_string_free): Remove; not used.
13265 (percent_percent_count): Move decl to just before use.
13266 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
13267 not the (never otherwised-used) CHARACTER.
13268
13269 2002-11-07 Akim Demaille <akim@epita.fr>
13270
13271 Let yyerror always receive the msg as last argument, so that
13272 yyerror can be variadic.
13273
13274 * data/yacc.c (b4_yyerror_args): New.
13275 Use it when calling yyerror.
13276 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
13277 Use it when calling yyerror.
13278 * doc/bison.texinfo (Error Reporting): Adjust.
13279 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
13280 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
13281
13282 2002-11-06 Akim Demaille <akim@epita.fr>
13283
13284 #line should have quoted strings.
13285 Ideally, this should be done by m4_quotearg.
13286
13287 * src/scan-skel.l: Include quotearg.h.
13288 Quote __ofile__.
13289 * src/output.c (symbol_printers_output)
13290 (symbol_destructors_output): Quote the file name.
13291
13292 2002-11-06 Akim Demaille <akim@epita.fr>
13293
13294 * tests/regression.at (Invalid inputs): Adjust to the recent
13295 messages.
13296
13297 2002-11-06 Akim Demaille <akim@epita.fr>
13298
13299 Restore --no-lines.
13300 Reported by Jim Kent.
13301
13302 * data/c.m4 (b4_syncline): New.
13303 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
13304 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
13305 * src/output.c (user_actions_output): Likewise.
13306 (prepare): Define 'b4_synclines_flag'.
13307 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
13308
13309 2002-11-06 Akim Demaille <akim@epita.fr>
13310
13311 * src/main.c (main): Free `infile'.
13312 * src/scan-gram.l (handle_syncline): New.
13313 Recognize `#line'.
13314 * src/output.c (user_actions_output, symbol_destructors_output)
13315 (symbol_printers_output): Use the location's file name, not
13316 infile.
13317 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13318
13319 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13320
13321 * src/tables.c (matching_state): Don't allow states to match if
13322 either has GLR conflict entries.
13323
13324 2002-11-05 Paul Eggert <eggert@twinsun.com>
13325
13326 * src/scan-gram.l: Use more accurate diagnostics, e.g.
13327 "integer out of range" rather than "invalid value".
13328 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
13329 accordingly.
13330
13331 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
13332 Also, remove one static variable in the scanner.
13333
13334 * src/scan-gram.l (braces_level): Now auto, not static.
13335 Initialize to zero if the compiler is being picky.
13336 (INITIAL): Clear braces_level instead of incrementing it.
13337 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
13338 as POSIX 1003.1-2001 requires.
13339 * src/system.h (IF_LINT): New macro, taken from coreutils.
13340 * configure.ac: Define "lint" if --enable-gcc-warnings.
13341
13342 2002-11-05 Akim Demaille <akim@epita.fr>
13343
13344 * src/scan-gram.l: When it starts with `%', complain about the
13345 whole directive, not just that `invalid character: %'.
13346
13347 2002-11-04 Akim Demaille <akim@epita.fr>
13348
13349 * Makefile.maint: Update from Autoconf.
13350 (update, cvs-update, po-update, do-po-update): New.
13351
13352 2002-11-04 Akim Demaille <akim@epita.fr>
13353
13354 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
13355 and yyerror.
13356 Have yyerror `use' its arguments.
13357 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
13358 returns true when location & yacc & pure & parse-param.
13359 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
13360
13361 2002-11-04 Akim Demaille <akim@epita.fr>
13362
13363 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
13364 clashes.
13365 * src/scan-gram.l: Use [\'] instead of ['] to pacify
13366 font-lock-mode.
13367 Use complain_at.
13368 Use quote, not quote_n since LOCATION_PRINT no longer uses the
13369 slot 0.
13370
13371 2002-11-03 Paul Eggert <eggert@twinsun.com>
13372
13373 * src/reader.c (get_merge_function, grammar_current_rule_check):
13374 Use consistent diagnostics for reporting type name clashes.
13375 Quote the types with <>, for consistency with Yacc.
13376 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
13377
13378 2002-11-03 Akim Demaille <akim@epita.fr>
13379
13380 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
13381 New.
13382 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
13383 (b4_parse_param): Remove.
13384 Use b4_identification.
13385 Propagate b4_pure_args where needed to pass them to yyerror.
13386 * data/glr.m4 (b4_parse_param): Remove.
13387 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
13388 (b4_lpure_formals): New.
13389 Use b4_identification.
13390 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
13391 b4_user_formals and b4_user_args.
13392 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
13393 (yyreportAmbiguity): When using a pure parser, also need
13394 the location, and the parse-params.
13395 Adjust callers.
13396 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
13397 When using a pure parser, also need the parse-params.
13398 Adjust callers.
13399 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
13400 (%pure-parser + %parse-param) LALR and GLR parsers.
13401 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
13402 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
13403 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
13404 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

13406 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
13407 * doc/bison.texinfo: Untabify the whole file.
13408 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
13409 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
13410 (Error Reporting): Adjust to these new directives.
13411 Document %error-verbose, deprecate YYERROR_VERBOSE.
13412
13413 2002-11-03 Akim Demaille <akim@epita.fr>
13414
13415 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
13416 AT_CHECK_CALC_GLR invocations to use % directives, instead of
13417 command line options.
13418 * tests/cxx-type.at: Formatting changes.
13419
13420 2002-11-03 Paul Eggert <eggert@twinsun.com>
13421
13422 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
13423 to count columns correctly, and to check for invalid inputs.
13424
13425 Use mbsnwidth to count columns correctly. Account for tabs, too.
13426 Include mbswidth.h.
13427 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
13428 (extend_location): New function.
13429 (YY_LINES): Remove.
13430
13431 Handle CRLF in C code rather than in Lex code.
13432 (YY_INPUT): New macro.
13433 (no_cr_read): New function.
13434
13435 Scan UCNs, even though we don't fully handle them yet.
13436 (convert_ucn_to_byte): New function.
13437
13438 Handle backslash-newline correctly in C code.
13439 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
13440 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
13441 all uses changed.
13442 (tag, splice): New EREs. Do not allow NUL or newline in tags.
13443 Use {splice} wherever C allows backslash-newline.
13444 YY_STEP after space, newline, vertical-tab.
13445 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
13446
13447 (letter, id): Don't assume ASCII; e.g., spell out a-z.
13448
13449 ({int}, handle_action_dollar, handle_action_at): Check for integer
13450 overflow.
13451
13452 (YY_STEP): Omit trailing semicolon, so that it's more like C.
13453
13454 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
13455 as well as \000. Check for UCHAR_MAX, not 255.
13456 Allow \x with an arbitrary positive number of digits, as in C.
13457 Check for overflow here.
13458 Allow \? and UCNs, for compatibility with C.
13459
13460 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
13461 with quote slot used by complain_at.
13462
13463 * tests/input.at: Add tests for backslash-newline, m4 quotes
13464 in symbols, long literals, and funny escapes in strings.
13465
13466 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
13467 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
13468 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
13469 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
13470 * m4/mbswidth.m4: New file, from GNU coreutils.
13471
13472 * doc/bison.texinfo (Grammar Outline): Document // comments.
13473 (Symbols): Document that trigraphs have no special meaning in Bison,
13474 nor is backslash-newline allowed.
13475 (Actions): Document that trigraphs have no special meaning.
13476
13477 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
13478 no longer used.
13479
13480 2002-11-02 Paul Eggert <eggert@twinsun.com>
13481
13482 * src/reader.c: Don't include quote.h; not needed.
13483 (get_merge_function): Reword warning to be consistent with
13484 type clash diagnostic in grammar_current_rule_check.
13485
13486 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
13487 bug in trigraph handling.
13488
13489 * src/output.c (prepare_symbols): When printing token names,
13490 escape "[" as "@<:@" and likewise for "]".
13491
13492 * src/system.h (errno): Remove declaration, as we are now
13493 assuming C89 or better, and C89 guarantees errno.
13494
13495 2002-10-30 Paul Eggert <eggert@twinsun.com>
13496
13497 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
13498 Check for close failures.
13499 * src/files.h (xfclose): Return void, not int, since it always
13500 returned zero.
13501 * src/files.c (xfclose): Likewise. Report I/O error if ferror
13502 indicates one.
13503 * src/output.c (output_skeleton): Use xfclose rather than fclose
13504 and ferror. xfclose now checks ferror.
13505
13506 * data/glr.c (YYLEFTMOST_STATE): Remove.
13507 (yyreportTree): Use a stack-based leftmost state. This avoids
13508 our continuing battles with bogus warnings about initializers.
13509
13510 2002-10-30 Akim Demaille <akim@epita.fr>
13511
13512 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
13513 #if.
13514
13515 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13516
13517 * tests/glr-regr1.at: New test for reported regressions.
13518 * tests/testsuite.at: Add glr-regr1.at test.
13519 * tests/Makefile.am: Add glr-regr1.at test.
13520
13521 2002-10-24 Paul Eggert <eggert@twinsun.com>
13522
13523 Version 1.75a.
13524
13525 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
13526 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
13527 we use malloc. Don't assume 'A' through 'Z' are contiguous.
13528 Don't assume strdup exists; POSIX says its an XSI extension.
13529 Check for buffer overflow on input.
13530
13531 2002-10-24 Akim Demaille <akim@epita.fr>
13532
13533 * src/output.c (output_skeleton): Don't disable M4sugar comments
13534 too soon: it results in comments being expanded.
13535 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
13536 first output.
13537
13538 2002-10-24 Akim Demaille <akim@epita.fr>
13539
13540 * data/yacc.c (m4_int_type): New.
13541 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
13542 char' as only yacc.c wants K&R portability.
13543 * data/glr.c (yysigned_char): Remove.
13544 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
13545 Reported by Quoc Peyrot.
13546
13547 2002-10-23 Paul Eggert <eggert@twinsun.com>
13548
13549 * src/main.c (main): With --trace=time, report times even if a
13550 non-fatal error occurs. Formerly, the times were reported in some
13551 such cases but not in others.
13552 * src/reader.c (reader): Just return if a complaint has been issued,
13553 instead of exiting, so that 'main' can report times.
13554
13555 2002-10-22 Akim Demaille <akim@epita.fr>
13556
13557 * src/system.h: Include sys/types.
13558 Reported by Bert Deknuydt.
13559
13560 2002-10-23 Paul Eggert <eggert@twinsun.com>
13561
13562 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
13563 Suggested by Art Haas.
13564
13565 2002-10-22 Paul Eggert <eggert@twinsun.com>
13566
13567 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
13568 decl; not needed any more.
13569 * src/main.c (main): Use return to exit, undoing yesterday's change.
13570 The last OS that we could find where this wouldn't work is
13571 SunOS 3.5, and that's too old to worry about now.
13572
13573 * data/glr.c (struct yyltype): Define members even when not
13574 doing locations. This is more consistent with yacc.c, and it
13575 works around the following bug reports:
13576 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
13577 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
13578
13579 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
13580 @acronym consistently. Standardize on "Yacc" instead of "YACC",
13581 "Algol" instead of "ALGOL". Give a bit more history about BNF.
13582
13583 2002-10-22 Akim Demaille <akim@epita.fr>
13584
13585 * data/README: New.
13586
13587 2002-10-21 Paul Eggert <eggert@twinsun.com>
13588
13589 Be consistent about 'bool'; the old code used an enum in one
13590 module and an int in another, and this violates the C standard.
13591 * m4/stdbool.m4: New file, from coreutils 4.5.3.
13592 * configure.ac (AC_HEADER_STDBOOL): Add.
13593 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
13594 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
13595 * src/symtab.c (hash_compare_symbol_t): Likewise.
13596 * src/system.h (bool, false, true): Use a definition consistent
13597 with ../lib/hash.c. All uses changed.
13598
13599 * src/complain.c (warning_issued): Renamed from warn_message_count,
13600 so that we needn't worry about integer overflow (!).
13601 Now of type bool. All uses changed.
13602 (complaint_issued): Renamed from complain_message_count; likewise.
13603
13604 * src/main.c (main): Use exit to exit with failure.
13605
13606 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
13607 rather than 1 and 0.
13608 * src/main.c (main): Likewise.
13609 * src/getargs.c (getargs): Likewise.
13610 * src/reader.c (reader): Likewise.
13611
13612 * src/getarg.c (getargs): Remove duplicate code for
13613 "Try `bison --help'".
13614
13615 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
13616 What was that "2" for?
13617
13618 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
13619 * src/getargs.c (usage): Likewise.
13620
13621 * src/getargs.c (getargs): When there are too few operands, report
13622 the last one. When there are too many, report the first extra
13623 one. This is how diffutils does it.
13624
13625 2002-10-20 Paul Eggert <eggert@twinsun.com>
13626
13627 Remove K&R vestiges.
13628 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
13629 * src/complain.c (VA_START): Remove. Assume prototypes.
13630 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
13631 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
13632 fatal): Assume prototypes.
13633 * src/complain.h: Assume prototypes.
13634 * src/system.h (PARAMS): Remove.
13635 Include <limits.h> unconditionally, since it's guaranteeed even
13636 for a freestanding C89 compiler.
13637 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
13638 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.

13656 (b4_c_function_decl, b4_c_ansi_function_def)
13657 (b4_c_ansi_function_decl): New.
13658 Change the interpretation of the arguments: before `int, foo', now

13661 Adjust b4_c_function_def uses.
13662 * data/glr.c (yyparse): Likewise, but ANSI only.

13699 2002-10-19 Paul Eggert <eggert@twinsun.com>
13700
13701 Do not create a temporary file, as that involves security and
13702 cleanup headaches. Instead, use a pair of pipes.
13703 Derived from a suggestion by Florian Krohm.
13704 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
13705 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
13706 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
13707 (BISON_PREREQ_SUBPIPE): Add.
13708 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
13709 Add subpipe.h, subpipe.c.

13712 * src/output.c: Include "subpipe.h".
13713 (m4_invoke): Remove decl.
13714 (scan_skel): New decl.
13715 (output_skeleton): Use pipe rather than temporary file for m4 input.
13716 Check that m4sugar.m4 is readable, to avoid deadlock.
13717 Check for pipe I/O error.
13718 * src/scan-skel.l (readpipe): Remove decl.
13719 (scan_skel): New function, to be used in place of m4_invoke.
13720 Read from stream rather than file.
13721
13722 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
13723 float, as this generates a warning on Solaris 8 + GCC 3.2 with
13724 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
13725 this generates a more-accurate value anyway.
13726
13727 * lib/timevar.c (timervar_accumulate): Rename locals to
13728 avoid confusion with similarly-named more-global.
13729 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
13730
13731 * src/output.c (prepare): Use xstrdup to convert char const *
13732 to char *, to avoid GCC warning.
13733
13734 2002-10-19 Akim Demaille <akim@epita.fr>
13735
13736 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
13737 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
13738 Use them to have `calc.y' ready for %pure-parser.
13739 * data/yacc.c (YYLEX): Pass a yylex return type to
13740 b4_c_function_call.
13741
13742 2002-10-19 Akim Demaille <akim@epita.fr>
13743
13744 Prototype support of %lex-param and %parse-param.
13745
13746 * src/parse-gram.y: Add the definition of the %lex-param and
13747 %parse-param tokens, plus their rules.
13748 Drop the `_' version of %glr-parser.
13749 Add the "," token.
13750 * src/scan-gram.l (INITIAL): Scan them.
13751 * src/muscle_tab.c: Comment changes.
13752 (muscle_insert, muscle_find): Rename `pair' as `probe'.
13753 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
13754 (muscle_entry_s): The `value' member is no longer const.
13755 Adjust all dependencies.
13756 * src/muscle_tab.c (muscle_init): Adjust: use
13757 MUSCLE_INSERT_STRING.
13758 Initialize the obstack earlier.
13759 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
13760 (muscle_pair_list_grow): New.
13761 * data/c.m4 (b4_c_function_call, b4_c_args): New.
13762 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
13763 * tests/calc.at: Use %locations, not --locations.
13764 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
13765
13766 2002-10-19 Akim Demaille <akim@epita.fr>
13767
13768 * src/getargs.c (usage): Take status as argument and exit
13769 accordingly.
13770 Report the traditional `Try ... --help' message when status != 0.
13771 (usage, version): Don't take a FILE * as arg, it is pointless.
13772 (getargs): When there is an incorrect number of arguments, make it
13773 an error, and report it GNUlically thanks to `usage ()'.
13774
13775 2002-10-18 Paul Eggert <eggert@twinsun.com>
13776
13777 * data/glr.c (yyreportParseError): Don't assume that sprintf
13778 yields the length of the printed string, as this is not true
13779 on SunOS 4.1.4. Reported by Peter Klein.
13780
13781 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
13782 * tests/conflicts.at (%nonassoc and eof): Likewise.
13783 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
13784
13785 2002-10-17 Akim Demaille <akim@epita.fr>
13786
13787 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
13788 * src/getargs.c (trace_types, trace_args): Adjust.
13789 * src/reader.c (grammar_current_rule_prec_set)
13790 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
13791 Standardize error messages.
13792 And s/@prec/%prec/!
13793 (reader): Use trace_flag to enable scanner/parser debugging,
13794 instead of an adhoc scheme.
13795 * src/scan-gram.l: Remove trailing debugging code.
13796
13797 2002-10-16 Paul Eggert <eggert@twinsun.com>
13798
13799 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
13800 MUSCLE_TAB_H.
13801
13802 * NEWS: Officially drop support for building Bison with K&R C,
13803 since it didn't work anyway and it's not worth worrying about.
13804 * Makefile.maint (wget_files): Remove ansi2knr.c.
13805 (ansi2knr.c-url_prefix): Remove.
13806 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
13807 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13808 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13809
13810 2002-10-15 Paul Eggert <eggert@twinsun.com>
13811
13812 Stop using the "enum_" trick for K&R-style function definitions;
13813 it confused me, and I was the author! Instead, assume that people
13814 who want to use K&R C compilers (when using these modules in GCC,
13815 perhaps?) will run ansi2knr.
13816
13817 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
13818 All uses of "enum_" changed to "enum ".
13819 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

13829 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
13830 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
13831 Use function prototypes; this removes the need for declaring
13832 static functions simply to provide their prototypes.
13833 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

13890 2002-10-14 Akim Demaille <akim@epita.fr>
13891
13892 * tests/Makefile.am (maintainer-check-posix): New.
13893
13894 2002-10-14 Akim Demaille <akim@epita.fr>
13895
13896 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
13897 member.
13898
13899 2002-10-14 Akim Demaille <akim@epita.fr>
13900
13901 * src/tables.c (table_ninf_remap): base -> tab.
13902 Reported by Matt Rosing.
13903
13904 2002-10-14 Paul Eggert <eggert@twinsun.com>
13905
13906 * tests/action.at, tests/calc.at, tests/conflicts.at,
13907 tests/cxx-type.at, tests/headers.at, tests/input.at,
13908 tests/regression.at, tests/synclines.at, tests/torture.at:
13909 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
13910 so that the tests still work even if POSIXLY_CORRECT is set.
13911 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
13912
13913 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
13914 for portability to K&R hosts. Fix typo: signed char is guaranteed
13915 only to 127, not to 128.
13916 * data/glr.c (yysigned_char): New type.
13917 * data/yacc.c (yysigned_char): Likewise.
13918 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
13919
13920 2002-10-13 Paul Eggert <eggert@twinsun.com>
13921
13922 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
13923 true due to limited range of data type" warning from GCC.
13924
13925 * data/c.m4 (b4_token_defines): Protect against double-inclusion
13926 by wrapping enum yytokentype's definition inside #ifndef
13927 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
13928
13929 2002-10-13 Akim Demaille <akim@epita.fr>
13930
13931 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
13932 Un yy- yyrhs to avoid the name clash with the global YYRHS.
13933
13934 2002-10-13 Akim Demaille <akim@epita.fr>
13935
13936 * Makefile.maint: Update from Autoconf 2.54.

13938
13939 2002-10-13 Akim Demaille <akim@epita.fr>
13940
13941 * src/print.c (print_state): Separate the list of solved conflicts
13942 from the other items.

13944
13945 2002-10-13 Akim Demaille <akim@epita.fr>
13946
13947 Let nondeterministic skeletons be usable with deterministic
13948 tables.
13949
13950 With the patch, GAWK compiled by GCC without -O2 passes its test
13951 suite using a GLR parser driven by LALR tables. It fails with -O2
13952 because `struct stat' gives two different answers on my machine:
13953 88 (definition of an auto var) and later 96 (memset on this var).
13954 Hence the stack is badly corrumpted. The headers inclusion is to
13955 blame: if I move the awk.h inclusion before GLR's system header
13956 inclusion, the two struct stat have the same size.
13957
13958 * src/tables.c (pack_table): Always create conflict_table.
13959 (token_actions): Always create conflict_list.
13960 * data/glr.c (YYFLAG): Remove, unused.
13961
13962 2002-10-13 Akim Demaille <akim@epita.fr>
13963
13964 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
13965 (O0FLAGS): New.
13966 (VALGRIND, GXX): New.
13967 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
13968 * tests/bison.in: Run $PREBISON a pre-command.
13969 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
13970 (maintainer-check-g++): New.
13971 * Makefile.am (maintainer-check): New.
13972
13973 2002-10-13 Akim Demaille <akim@epita.fr>
13974
13975 * data/glr.c: Formatting changes.
13976 Tweak some trace messages to match yacc.c's.
13977
13978 2002-10-13 Akim Demaille <akim@epita.fr>
13979
13980 GLR parsers sometimes raise parse errors instead of performing the
13981 default reduction.
13982 Reported by Charles-Henry de Boysson.
13983
13984 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
13985 check the length of the traces when %glr.
13986 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
13987 GLR's traces.
13988 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
13989 Test GLR parsers.
13990 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
13991 (yyltype): Remove the yy prefix from the member names.
13992 (yytable): Complete its comment.
13993 (yygetLRActions): Map error action number from YYTABLE from
13994 YYTABLE_NINF to 0.
13995 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
13996 (which was a bug: it should have been YYTABEL_NINF, and yet it was
13997 not satisfying as we could compare an YYACTION computed from
13998 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
13999 only value for error actions.
14000 (yyreportParseError): In verbose parse error messages, don't issue
14001 `error' in the list of expected tokens.
14002 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
14003 next action to perform to match glr.c's decoding.
14004 (yytable): Complete its comment.
14005

14007
14008 Fix problem reported by Henrik Grubbstroem in
14009 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
14010 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
14011 because the Bison parser reads the second action before reducing
14012 the first one.
14013 * src/scan-gram.l (rule_length): New static var.
14014 Use it to keep track of the rule length in the scanner, since
14015 we can't expect the parser to be in lock-step sync with the scanner.
14016 (handle_action_dollar, handle_action_at): Use this var.
14017 * tests/actions.at (Exotic Dollars): Test for the problem.
14018
14019 2002-10-12 Paul Eggert <eggert@twinsun.com>
14020
14021 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
14022 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
14023 Include <sys/time.h> when checking for clock_t and struct tms.
14024 Use same include order as source.
14025 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
14026 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
14027
14028 * lib/timevar.c: Update copyright date and clarify comments.
14029 (get_time) [IN_GCC]: Keep the GCC version for reference.
14030
14031 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
14032 GCC version as of today, then merge Bison's changes.
14033 Change "GCC" to "Bison" in copyright notice. timevar.def's
14034 author is Akim, so change that too.
14035
14036 * src/reader.c (grammar_current_rule_check):
14037 Don't worry about the default action if $$ is untyped.
14038 Prevents bogus warnings reported by Jim Gifford in
14039 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
14040
14041 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
14042 * data/glr.c, data/lalr1.cc, data/yacc.c:
14043 Output token definitions before the first part of user declarations.
14044 Fixes compatibility problem reported by Jim Gifford for kbd in
14045 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
14046
14047 2002-10-11 Paul Eggert <eggert@twinsun.com>
14048
14049 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
14050 (yyparse): here. This undoes some of the 2002-07-25 change.
14051 Compatibility problem reported by Ralf S. Engelschall with
14052 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
14053
14054 2002-10-11 Akim Demaille <akim@epita.fr>
14055
14056 * tests/regression.at Characters Escapes): New.
14057 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
14058 characters.
14059 Reported by Jan Nieuwenhuizen.
14060
14061 2002-10-11 Akim Demaille <akim@epita.fr>

14064
14065 2002-10-10 Paul Eggert <eggert@twinsun.com>
14066
14067 Portability fixes for bitsets; this also avoids several GCC
14068 warnings.
14069
14070 * lib/abitset.c: Include <stddef.h>, for offsetof.
14071 * lib/lbitset.c: Likewise.
14072
14073 * lib/abitset.c (abitset_bytes): Return a size that is aligned
14074 properly for vectors of objects. Do not assume that adding a
14075 header size to a multiple of a word size yields a value that is
14076 properly aligned for the whole union.
14077 * lib/bitsetv.c (bitsetv_alloc): Likewise.
14078
14079 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
14080 unique names for structures.
14081 * lib/ebitset.c (ebitset_bytes): Likewise.
14082 * lib/lbitset.c (lbitset_bytes): Likewise.
14083
14084 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
14085 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
14086 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
14087 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
14088 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
14089 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
14090 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
14091 to improve the type-checking that GCC can do.
14092 * lib/bitset.c (bitset_op4_cmp): Likewise.
14093 * lib/bitset_stats.c (bitset_stats_count,
14094 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
14095 bitset_stats_copy, bitset_stats_disjoint_p,
14096 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
14097 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
14098 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
14099 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
14100 bitset_stats_and_or_cmp, bitset_stats_andn_or,
14101 bitset_stats_andn_or_cmp, bitset_stats_or_and,
14102 bitset_stats_or_and_cmp): Likewise.
14103 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
14104 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
14105 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
14106 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
14107
14108 * lib/abitset.h: Include bitset.h, not bbitset.h.
14109 * lib/ebitset.h: Likewise.
14110 * lib/lbitset.h: Likewise.
14111
14112 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
14113 All instances of parameters of type enum bitset_opts are now of
14114 type enum_bitset_opts, to conform to the C Standard, and similarly
14115 for enum_bitset_type.
14116 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14117 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14118
14119 Do not use "struct bitset_struct" to mean different things in
14120 different modules. Not only is this confusing, it violates
14121 the C Standard, which requires that structure types in different
14122 modules must be compatible if one is to be passed to the other.
14123 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
14124 All instances of "struct bitset_struct *" replaced with "bitset".
14125 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
14126 (union bitset_union, struct abitset_struct, struct ebitset_struct,
14127 struct lbitset_struct, struct bitset_stats_struct): New types.
14128 All uses of struct bitset_struct changed to union bitset_union,
14129 etc.
14130 * lib/abitset.c (struct abitset_struct, abitset,
14131 struct bitset_struct): Remove.
14132 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
14133 struct bitset_struct): Remove.
14134 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
14135 bitset_struct): Remove.
14136 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
14137 Likewise.
14138
14139 Do not call a function of type T using a call that assumes the
14140 function is of a different type U. Standard C requires that a
14141 function must be called with a type that is compatible with its
14142 definition.
14143 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
14144 New decls.
14145 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
14146 New functions.
14147 * lib/ebitset.c (PFV): Remove.
14148 * lib/lbitset.c (PFV): Likewise.
14149 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
14150 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
14151 decls.
14152 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
14153 (ebitset_vtable): Use them.
14154 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
14155 lbitset_xor): New functions.
14156 (lbitset_vtable): Use them.
14157
14158 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
14159 Declare.
14160
14161 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
14162 GCC warning.
14163 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
14164 Use offsetof, for simplicity.
14165
14166 2002-10-06 Paul Eggert <eggert@twinsun.com>
14167
14168 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
14169 the same width as int. This reapplies a hunk of the 2002-08-12 patch
14170 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
14171 which was inadvertently undone by the 2002-09-30 patch.
14172 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
14173 the same width as int.
14174
14175 2002-10-04 Paul Eggert <eggert@twinsun.com>
14176

14178
14179 * configure.ac (AC_INIT), NEWS: Increment version number.
14180
14181 * doc/bison.texinfo: Minor spelling, grammar, and white space
14182 fixes.
14183 (Symbols): Mention that any negative value returned from yylex
14184 signifies end-of-input. Warn about negative chars. Mention
14185 the portable Standard C character set.
14186
14187 The GNU coding standard says CFLAGS and YFLAGS are reserved
14188 for the installer to set.
14189 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
14190 * src/Makefile.am (AM_CFLAGS): Likewise.
14191 (AM_YFLAGS): Renamed from YFLAGS.
14192
14193 Fix some MAX and MIN problems.
14194 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
14195 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
14196 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
14197 * src/reader.c (reader): Use it.
14198
14199 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
14200 POSIX 1003.1-2001 has removed fgrep.
14201
14202 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
14203
14204 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
14205 interpreted as signed.
14206 * lib/ebitset.c (ebitset_list): Fix bug.
14207
14208 2002-10-01 Paul Eggert <eggert@twinsun.com>

14214 Use bitset_bindex, not int or unsigned int or size_t, to count bits.
14215 * lib/bbitset.h (struct bitset_vtable.size, struct bitset_vtable.count,
14216 struct bitset_vtable.list, struct bitset_vtable.list_reverse,

14231 Likewise.
14232 * lib/lbitset.c (lbitset_size, lbitset_list, lbitset_list_merge):
14233 Likewise.
14234
14235 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
14236 Use size_t, not unsigned int, to count bytes.
14237 * lib/abitset.h (abitset_bytes): Likewise.
14238 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):
14239 Likewise.

14253 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
14254 abitset_or_and, abitset_or_and_cmp):
14255 Use bitset_windex instead of unsigned int.
14256 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
14257 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
14258 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,
14259 ebitset_elt_find, ebitset_list_reverse, ebitset_list, ebitset_init):

14272 BITSET_SIZE_MAX): New macros.
14273 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
14274 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
14275 to BITSET_WINDEX_MAX.
14276
14277 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
14278 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

14377 2002-09-06 Paul Eggert <eggert@twinsun.com>
14378
14379 * doc/bison.texinfo (Conditions): Make explicit that the GPL
14380 exception applies only to yacc.c. This is a modification of a
14381 patch originally suggested by Akim Demaille.
14382
14383 2002-09-06 Akim Demaille <akim@epita.fr>
14384
14385 * data/c.m4 (b4_copyright): Move the GPL exception comment from
14386 here to...
14387 * data/yacc.c: here.
14388
14389 * data/lalr1.cc (struct yyltype): Don't define it, since we use
14390 LocationType.
14391 (b4_ltype): Default to yy::Location from location.hh.
14392
14393 2002-09-04 Jim Meyering <jim@meyering.net>
14394
14395 * data/yacc.c: Guard the declaration of yytoknum also with
14396 `#ifdef YYPRINT', so it is declared only when used.
14397
14398 2002-09-04 Akim Demaille <akim@epita.fr>
14399
14400 * configure.in: Rename as...
14401 * configure.ac: this.
14402 Bump to 1.49c.
14403
14404 2002-09-04 Akim Demaille <akim@epita.fr>
14405

14407 * src/lalr.c, src/LR0.c, src/relation.c, src/tables.c: Don't
14408 translate maintainer only messages.
14409
14410 2002-08-12 Paul Eggert <eggert@twinsun.com>
14411

14413
14414 * Makefile.am (SUBDIRS): Remove intl.
14415 (DISTCLEANFILES): Remove.
14416 * NEWS: Mention that GNU M4 is now required. Clarify what is

14428 (yyreportParseError): Use size_t for yysize.
14429 (yy_yypstack): No longer nested inside yypstates, as nested
14430 functions are not portable. Do not assume size_t is the
14431 same width as int.
14432 (yypstates): Do not assume that ptrdiff_t is the same width
14433 as int, and similarly for yyposn and YYINDEX.
14434
14435 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
14436
14437 * lib/Makefile.am (INCLUDES): Do not include from the intl
14438 directory, which has been removed.
14439 * src/Makefile.am (INCLUDES): Likewise.
14440

14445 * lib/Makefile.am (libbison_a_SOURCES): Avoid +=, a GNU make extension.
14446 * tests/Makefile.am (EXTRA_DIST): Likewise.
14447
14448 * lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):
14449 Do not assume that bitset_windex is the same width as unsigned.

14470
14471 * lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
14472 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
14473
14474 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
14475 PROTOTYPES to check for prototypes, and "defined __STDC__" to
14476 check for void *.
14477
14478 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
14479 size_t; the old version tried to do this but casted improperly.
14480 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
14481 (bitset_test): Now returns int, not unsigned long.
14482
14483 * lib/bitset_stats.c: Include "gettext.h".
14484 (_): New macro.
14485 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
14486 name locals "index", as it generates unnecessary warnings on some
14487 hosts that have an "index" function.
14488
14489 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
14490 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

14495 * src/closure.c (print_closure, set_firsts, closure): Likewise.
14496 * src/gram.c (grammar_dump): Likewise.
14497 * src/injections.c (injections_compute): Likewise.
14498 * src/lalr.c (lookaheads_print): Likewise.
14499 * src/relation.c (relation_transpose): Likewise.
14500 * src/scan-gram.l: Likewise.
14501 * src/tables.c (table_grow, pack_vector): Likewise.
14502
14503 * m4/Makefile.am (EXTRA_DIST): Remove codeset.m4,
14504 glibc21.m4, isc-posix.m4 lcmessage.m4, stage.m4.
14505 * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.
14506 * m4/mbstate_t.m4: Sync with fileutils.
14507 * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.

14511 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
14512 lib/timevar.c.
14513 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
14514 manual recommends.
14515 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
14516
14517 * src/complain.c (strerror_r): Remove decl; not needed.
14518 (strerror): Use same pattern as ../lib/error.c.
14519
14520 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
14521
14522 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
14523
14524 * src/main.c (main): Cast result of bindtextdomain and textdomain
14525 to void, to avoid a GCC warning when --disable-nls is in effect.
14526
14527 * src/scan-gram.l: Use strings rather than escapes when possible,
14528 to minimize the number of warnings from xgettext.
14529 (handle_action_dollar, handle_action_at): Don't use isdigit,
14530 as it mishandles negative chars and it may not work as expected
14531 outside the C locale.
14532
14533 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14534 this is a GCC extension and is not portable to other compilers.
14535
14536 * src/system.h (alloca): Use same pattern as ../lib/error.c.
14537 Do not include <ctype.h>; no longer needed.
14538 Do not include <malloc.h>; no longer needed (and generates
14539 warnings on OpenBSD 3.0).
14540
14541 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
14542 it's not portable.
14543
14544 * tests/regression.at: Do not use 'cc -c input.c -o input';
14545 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
14546
14547 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
14548 exit status as failure, not just exit status 1. Sun C exits
14549 with status 2 sometimes.
14550
14551 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
14552 Use it for the two large tests.
14553
14554 2002-08-02 Akim Demaille <akim@epita.fr>
14555
14556 * src/conflicts.c (conflicts_output): Don't output rules never
14557 reduced here, since anyway that computation doesn't work.
14558 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
14559 (rule_useless_p, rule_never_reduced_p): New.
14560 (grammar_rules_partial_print): Use a filter instead of a range.
14561 Display the title only if needed.
14562 (grammar_rules_print): Adjust.
14563 (grammar_rules_never_reduced_report): New.
14564 * src/tables.c (action_row): Move the computation of rules never
14565 reduced to...
14566 (token_actions): here.
14567 * src/main.c (main): Make the parser before making the report, so
14568 that rules never reduced are computed.
14569 Call grammar_rules_never_reduced_report.
14570 * src/print.c (print_results): Report rules never reduced.
14571 * tests/conflicts.at, tests/reduce.at: Adjust.
14572
14573 2002-08-01 Akim Demaille <akim@epita.fr>
14574
14575 Instead of attaching lookaheads and duplicating the rules being
14576 reduced by a state, attach the lookaheads to the reductions.
14577
14578 * src/state.h (state_t): Remove the `lookaheads',
14579 `lookaheads_rule' member.
14580 (reductions_t): Add a `lookaheads' member.
14581 Use a regular array for the `rules'.
14582 * src/state.c (reductions_new): Initialize the lookaheads member
14583 to 0.
14584 (state_rule_lookaheads_print): Adjust.

14589 (add_lookback_edge): Adjust.
14590 (state_lookaheads_count): New.
14591 (states_lookaheads_initialize): Merge into...
14592 (initialize_LA): this.
14593 (lalr_free): Adjust.
14594 * src/main.c (main): Don't free nullable and derives too early: it
14595 is used by --verbose.
14596 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
14597
14598 2002-08-01 Akim Demaille <akim@epita.fr>
14599
14600 * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
14601 `rule_number_t**'.

14604 Adjust all dependencies.
14605 * src/nullable.c (set_nullable, free_nullable): Rename as...
14606 (nullable_compute, nullable_free): these.
14607 (rule_list_t): Store rule_t *, not rule_number_t.
14608 * src/state.c (state_rule_lookaheads_print): Directly compare rule
14609 pointers, instead of their numbers.
14610 * src/main.c (main): Call nullable_free, and derives_free earlier,
14611 as they were lo longer used.
14612
14613 2002-08-01 Akim Demaille <akim@epita.fr>
14614
14615 * lib/timevar.c (get_time): Include children time.
14616 * src/lalr.h (LA, LArule): Don't export them: used with the
14617 state_t.
14618 * src/lalr.c (LA, LArule): Static.
14619 * src/lalr.h, src/lalr.c (lalr_free): New.
14620 * src/main.c (main): Call it.
14621 * src/tables.c (pack_vector): Check whether loc is >= to the
14622 table_size, not >.
14623 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
14624 (tables_generate): do it, since that's also it which allocates
14625 them.
14626 Don't free LA and LArule, main does.
14627
14628 2002-07-31 Akim Demaille <akim@epita.fr>
14629
14630 Separate parser tables computation and output.
14631

14633 (conflict_list, conflict_list_cnt, table, check, table_ninf)
14634 (yydefgoto, yydefact, high): Move to...
14635 * src/tables.h, src/tables.c: here.

14641 (conflict_list_free, table_size, lowzero, table_grow, conflict_row)
14642 (action_row, save_row, token_actions, save_column, default_goto)
14643 (goto_actions, sort_actions, matching_state, pack_vector)
14644 (table_ninf_remap, pack_table, prepare_actions): Move to...

14664 * src/getargs.h, src/getargs.c: Support trace_time for
14665 --trace=time.
14666 * src/main.c (stage): Remove.
14667 (main): Replace `stage' invocations with timevar calls.
14668 * src/output.c: Insert pertinent timevar calls.
14669
14670 2002-07-31 Akim Demaille <akim@epita.fr>
14671
14672 Let --trace have arguments.
14673
14674 * src/getargs.h (enum trace_e): New.
14675 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
14676 (long_options, short_options): --trace/-T takes an optional
14677 argument.
14678 Change all the uses of trace_flag to reflect the new flags.
14679 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
14680
14681 Strengthen `stage' portability.
14682
14683 * m4/stage.m4 (BISON_PREREQ_STAGE): New.
14684 * configure.in: Use it.
14685 Don't check for malloc.h and sys/times.h.
14686 * src/system.h: Include them when appropriate.
14687 * src/main.c (stage): Compile only when mallinfo, struct mallinfo,
14688 times and struct tms are available.
14689
14690 2002-07-30 Akim Demaille <akim@epita.fr>
14691
14692 In verbose parse error message, don't report `error' as an
14693 expected token.
14694 * tests/actions.at (Printers and Destructors): Adjust.
14695 * tests/calc.at (Calculator $1): Adjust.
14696 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
14697 error message, do not report the parser accepts the error token in
14698 that state.
14699
14700 2002-07-30 Akim Demaille <akim@epita.fr>
14701

14712 Report rules which are never reduced by the parser: those hidden
14713 by conflicts.
14714
14715 * src/LR0.c (save_reductions): Don't make the final state too
14716 different: save its reduction (accept) instead of having a state
14717 without any action (no shift or goto, no reduce).
14718 Note: the final state is now a ``regular'' state, i.e., the
14719 parsers now contain `reduce 0' as default reduction.
14720 Nevertheless, since they decide to `accept' when yystate =
14721 final_state, they still will not reduce rule 0.
14722 * src/print.c (print_actions, print_reduction): Adjust.
14723 * src/output.c (action_row): Track reduced rules.
14724 (token_actions): Report rules never reduced.

14726
14727 2002-07-30 Akim Demaille <akim@epita.fr>

14730 Initiate its autoconfiscation.
14731
14732 * configure.in: Look for malloc.h and sys/times.h.
14733 * src/main.c (stage): Adjust.
14734 Report only when trace_flag.
14735
14736 2002-07-29 Akim Demaille <akim@epita.fr>
14737
14738 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not
14739 state_number_t.
14740 (errs_t): symbol_t*, not symbol_number_t.
14741 (reductions_t): rule_t*, not rule_number_t.

14743 * src/LR0.c, src/conflicts.c, src/lalr.c, src/output.c
14744 * src/print.c, src/print_graph.c: Adjust.
14745
14746 2002-07-29 Akim Demaille <akim@epita.fr>
14747
14748 Use $accept and $end, as BYacc and BTYacc do, instead of $axiom and $.
14749
14750 * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
14751 (endtoken, accept): these.
14752 * src/reader.c (reader): Set endtoken's default tag to "$end".
14753 Set undeftoken's tag to "$undefined" instead of "$undefined.".
14754 * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
14755 Adjust.
14756
14757 2002-07-29 Akim Demaille <akim@epita.fr>
14758
14759 * src/reduce.c (reduce_grammar): When the language is empty,
14760 complain about the start symbol, not the axiom.
14761 Use its location.
14762 * tests/reduce.at (Empty Language): New.
14763
14764 2002-07-26 Akim Demaille <akim@epita.fr>
14765
14766 * src/reader.h, src/reader.c (gram_error): ... can't get
14767 yycontrol without making too strong assumptions on the parser
14768 itself.
14769 * src/output.c (prepare_tokens): Use the real 0th value of
14770 token_translations instead of `0'.
14771 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
14772 visible here.
14773 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
14774 for the time being: %locations ought to provide it to yyerror.
14775
14776 2002-07-25 Akim Demaille <akim@epita.fr>
14777
14778 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
14779 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.

15938
15939 Remove `%thong' support as it is undocumented, unused, duplicates
15940 `%token's job, and creates useless e-mail traffic with people who

16448 * src/lex.c, src/nullable.c, src/output.c, src/print.c,
16449 * src/print_graph.c, src/reader.c, src/reduce.c, src/state.h,
16450 * src/symtab.c, src/symtab.h: Use token_number_t instead of shorts.
16451
16452 2002-04-22 Akim Demaille <akim@epita.fr>
16453
16454 * src/output.h, src/output.c (get_lines_number): Remove.
16455
16456 2002-04-19 Akim Demaille <akim@epita.fr>
16457
16458 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
16459 as Lex/Flex'.
16460 (Debugging): More details about enabling the debugging features.
16461 (Table of Symbols): Describe $$, $n, @$, and @n.
16462 Suggested by Tim Josling.
16463
16464 2002-04-19 Akim Demaille <akim@epita.fr>
16465
16466 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
16467
16468 2002-04-10 Akim Demaille <akim@epita.fr>
16469
16470 * src/system.h: Rely on HAVE_LIMITS_H.
16471 Suggested by Paul Eggert.
16472
16473 2002-04-09 Akim Demaille <akim@epita.fr>
16474
16475 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
16476 full stderr, and strip it according to the bison options, instead
16477 of composing the error message from different bits.
16478 This makes it easier to check for several error messages.
16479 Adjust all the invocations.
16480 Add an invocation exercising the error token.
16481 Add an invocation demonstrating a stupid error message.
16482 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
16483 Adjust the tests.
16484 Error message are for stderr, not stdout.
16485
16486 2002-04-09 Akim Demaille <akim@epita.fr>
16487
16488 * src/gram.h, src/gram.c (error_token_number): Remove, use
16489 errtoken->number.
16490 * src/reader.c (reader): Don't specify the user token number (2)
16491 for $undefined, as it uselessly prevents using it.
16492 * src/gram.h (token_number_t): Move to...
16493 * src/symtab.h: here.
16494 (state_t.number): Is a token_number_t.
16495 * src/print.c, src/reader.c: Use undeftoken->number instead of
16496 hard coded 2.
16497 (Even though this 2 is not the same as above: the number of the
16498 undeftoken remains being 2, it is its user token number which
16499 might not be 2).
16500 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
16501 `user_token_number_max'.
16502 Output `undef_token_number'.
16503 * data/bison.simple, data/bison.c++: Use them.
16504 Be sure to map invalid yylex return values to
16505 `undef_token_number'. This saves us from gratuitous SEGV.
16506
16507 * tests/conflicts.at (Solved SR Conflicts)
16508 (Unresolved SR Conflicts): Adjust.
16509 * tests/regression.at (Web2c Actions): Adjust.

16514 Adding #line.
16515 Remove the duplicate `typedefs'.
16516 (RhsNumberType): Fix the declaration and various other typos.
16517 Use __ofile__.
16518 * data/bison.simple: Use __ofile__.
16519 * src/scan-skel.l: Handle __ofile__.
16520
16521 2002-04-08 Akim Demaille <akim@epita.fr>
16522
16523 * src/gram.h (item_number_t): New, the type of item numbers in
16524 RITEM. Note that it must be able to code symbol numbers as
16525 positive number, and the negation of rule numbers as negative
16526 numbers.
16527 Adjust all dependencies (pretty many).
16528 * src/reduce.c (rule): Remove this `short *' pointer: use
16529 item_number_t.
16530 * src/system.h (MINSHORT, MAXSHORT): Remove.
16531 Include `limits.h'.
16532 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
16533 (shortcpy): Remove.

16538 * tests/torture.at (Big triangle): Move the limit from 254 to
16539 500.
16540 * tests/regression.at (Web2c Actions): Ajust.
16541
16542 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
16543 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
16544 passes, but produces negative #line number, once fixed, GCC is
16545 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
16546 C), it passes.
16547 * src/state.h (state_h): Code input lines on ints, not shorts.
16548
16549 2002-04-08 Akim Demaille <akim@epita.fr>
16550
16551 * src/reduce.c (reduce_grammar): First reduce the nonterminals,

16561 * src/output.c (output_table_data): Return the longest number.
16562 (prepare_tokens): Output `token_number_max').
16563 * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
16564 New.
16565 Use them to define yy_token_number_type/TokenNumberType.
16566 Use this type for yytranslate.
16567 * tests/torture.at (Big triangle): Push the limit from 124 to
16568 253.
16569 * tests/regression.at (Web2c Actions): Adjust.
16570
16571 2002-04-07 Akim Demaille <akim@epita.fr>
16572
16573 * tests/torture.at (Big triangle): New.
16574 (GNU AWK Grammar, GNU Cim Grammar): Move to...

16640
16641 * src/gram.h (rule_s): prec and precsym are now pointers
16642 to the bucket giving the priority/associativity.

16674
16675 2002-04-07 Akim Demaille <akim@epita.fr>

16681 (prepare_tokens): this.

16701 new_state.
16702 * src/closure.c (closure): Now that the initial state has its
16703 items properly set, there is no need for a special case when
16704 creating `ruleset'.
16705
16706 As a result, now the rule 0, reducing to $axiom, is visible in the
16707 outputs. Adjust the test suite.

16723 bucket.

16726 `number' of the buckets too.
16727 * src/gram.h: Include `symtab.h'.
16728 (associativity): Move to...

16742 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

16745 2002-04-07 Akim Demaille <akim@epita.fr>
16746
16747 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
16748 lacking `+ 1' to nrules, Bison reported as useless a token if it
16749 was used solely to set the precedence of the last rule...
16750
16751 2002-04-07 Akim Demaille <akim@epita.fr>
16752
16753 * data/bison.c++, data/bison.simple: Don't output the current file
16754 name in #line, to avoid useless diffs between two identical
16755 outputs under different names.

16758

16850
16851 * src/reader.c (read_additionnal_code): `c' should be an integer, not

17045 2002-02-14 Paul Eggert <eggert@twinsun.com>
17046
17047 Remove the support for C++ namespace cleanliness; it was
17048 causing more problems than it was curing, since it didn't work
17049 properly on some nonstandard C++ compilers. This can wait
17050 for a proper C++ parser.
17051
17052 * NEWS: Document this.
17053 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention

17092 2002-02-07 Robert Anisko <robert@lrde.epita.fr>

17095 more consistent when naming methods and variables. Put preprocessor
17096 directives around tables only needed for debugging.
17097
17098 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
17099

17140 (token_definitions_output): No longer keeps track of the output
17141 line number, hence remove the second argument.
17142 (guards_output): Check against the guard member of a rule, not the
17143 action member.
17144 Adjust callers.
17145 (output_skeleton): Don't look for the skeleton location, let m4 do
17146 that.
17147 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
17148 file will be used.
17149 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
17150 (prepare): Given that for the time being changesyntax is not
17151 usable in M4, rename the muscles using `-' to `_'.
17152 Define `defines_flag', `output_parser_name' and `output_header_name'.
17153 * src/output.h (actions_output, guards_output)
17154 (token_definitions_output): Adjust prototypes.
17155 * src/scan-skel.l: Instead of scanning the skeletons, it now
17156 processes the output of m4: `__oline__' and `#output'.

17158 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
17159 to date.

17182
17183 * src/bison.simple (YYSIZE_T): Do not define merely because
17184 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

17187 2002-01-27 Akim Demaille <akim@epita.fr>
17188
17189 Fix `%nonassoc and eof'.
17190
17191 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
17192 which were not properly copied! Replace
17193 memcpy (res->errs, src->errs, src->nerrs);
17194 with
17195 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
17196 !!!
17197 * tests/regression.at (%nonassoc and eof): Adjust to newest
17198 Autotest: `.' is not in the PATH.

17293 * src/getargs.c (AS_FILE_NAME): New.
17294 (getargs): Use it to convert DOSish file names.
17295 * src/files.c (base_name): Rename as full_base_name to avoid
17296 clashes with `base_name ()'.
17297 (filename_split): New.
17298 (compute_base_names): N-th rewrite, using filename_split.
17299
17300 2002-01-08 Akim Demaille <akim@epita.fr>
17301
17302 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
17303 New, stolen from the Fileutils 4.1.
17304 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
17305 * configure.in: Check for the presence of memrchr, and of its
17306 prototype.
17307
17308 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
17309
17310 * lib/hash.h (__P): Added definition for this macro.
17311 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
17312 BUILT_SOURCES, to ensure they are generated first.
17313 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
17314 %error-verbose to allow bootstrapping with bison 1.30x.
17315
17316 2002-01-06 Akim Demaille <akim@epita.fr>
17317
17318 * src/reader.c (parse_braces): Don't fetch the next char, the
17319 convention is to fetch on entry.
17320 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
17321 'switch' without a following semicolon.
17322 * tests/regression.at (braces parsing): New.
17323
17324 2002-01-06 Akim Demaille <akim@epita.fr>
17325
17326 Bison is dead wrong in its RR conflict reports.
17327
17328 * tests/torture.at (GNU Cim Grammar): New.
17329 * src/conflicts.c (count_rr_conflicts): Fix.
17330
17331 2002-01-06 Akim Demaille <akim@epita.fr>
17332
17333 Creating package.m4 from configure.ac causes too many problems.
17334
17335 * tests/Makefile.am (package.m4): Create it by hand,
17336 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
17337
17338 2002-01-06 Akim Demaille <akim@epita.fr>
17339
17340 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
17341 skeleton.h.
17342
17343 2002-01-04 Paul Eggert <eggert@twinsun.com>
17344
17345 * doc/bison.texinfo (Debugging):
17346 Remove YYSTDERR; it's no longer defined or used.
17347 Also, s/cstdio.h/cstdio/.
17348
17349 2002-01-03 Akim Demaille <akim@epita.fr>
17350
17351 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
17352
17353 2002-01-03 Akim Demaille <akim@epita.fr>
17354
17355 * src/parse-skel.y (process_skeleton): Don't bind the parser's
17356 tracing code to --trace, wait for a better --trace option, with
17357 args.
17358
17359 2002-01-03 Akim Demaille <akim@epita.fr>
17360
17361 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17362 The ISO C++ standard is extremely clear about it: stderr is
17363 considered a macro, not a regular symbol (see table 94 `Header
17364 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17365 Therefore std:: does not apply to it. It still does with fprintf.
17366 Also, s/cstdio.h/cstdio/.
17367
17368 2002-01-03 Akim Demaille <akim@epita.fr>
17369
17370 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17371 for non system headers.
17372
17373 2002-01-02 Akim Demaille <akim@epita.fr>
17374
17375 Equip the skeleton chain with location tracking, runtime trace,
17376 pure parser and scanner.
17377
17378 * src/parse-skel.y: Request a pure parser, locations, and prefix
17379 renaming.
17380 (%union): Having several members with the same type does not help
17381 type mismatches, simplify.
17382 (YYPRINT, yyprint): New.
17383 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17384 (skel_error): this.
17385 Handle locations.
17386 * src/scan-skel.l: Adjust to these changes.
17387 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17388 (LOCATION_PRINT, skel_control_t): New.
17389
17390 2001-12-30 Akim Demaille <akim@epita.fr>
17391
17392 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17393 replace `gb' with BLANKS.
17394 * src/scan-skel.l: Adjust.
17395
17396 2001-12-30 Akim Demaille <akim@epita.fr>
17397
17398 * src/system.h: We don't need nor want bcopy.
17399 Throw away MS-DOS crap: we don't need getpid.
17400 * configure.in: We don't need strndup. It was even causing
17401 problems: because Flex includes the headers *before* us,
17402 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17403 not visible.
17404 * lib/xstrndup.c: New.
17405 * src/scan-skel.l: Use it.
17406 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17407 * src/parse-skel.y: Use %directives instead of #defines.
17408
17409 2001-12-30 Akim Demaille <akim@epita.fr>
17410
17411 * src/skeleton.h: New.
17412 * src/output.c (output_parser, output_master_parser): Remove, dead
17413 code.
17414 * src/output.h (get_lines_number, actions_output, guards_output)
17415 (token_definitions_output): Prototype them.
17416 * src/parse-skel.y: Add the license notice.
17417 Include output.h and skeleton.h.
17418 (process_skeleton): Returns void, and takes a single parameter.
17419 * src/scan-skel.l: Add the license notice.
17420 Include skeleton.h.
17421 Don't use %option yylineno: it seems that then Flex imagines
17422 REJECT has been used, and therefore it won't reallocate its
17423 buffers (which makes no other sense to me than a bug). It results
17424 in warnings for `unused: yy_flex_realloc'.
17425
17426 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17427
17428 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17429 (MUSCLE_INSERT_PREFIX): ...to there.
17430 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17431 (MUSCLE_INSERT_PREFIX): Move from here...
17432
17433 * src/bison.hairy: Add a section directive. Put braces around muscle
17434 names. This parser skeleton is still broken, but Bison should not
17435 choke on a bad muscle 'syntax'.
17436 * src/bison.simple: Add a section directive. Put braces around muscle
17437 names.
17438
17439 * src/files.h (strsuffix, stringappend): Add declarations.
17440 (tab_extension): Add declaration.
17441 (short_base_name): Add declaration.
17442
17443 * src/files.c (strsuffix, stringappend): No longer static. These
17444 functions are used in the skeleton parser.
17445 (tab_extension): New.
17446 (compute_base_names): Use the computations done in this function
17447 to guess if the generated parsers should have '.tab' in their
17448 names.
17449 (short_base_name): No longer static.
17450
17451 * src/output.c (output_skeleton): New.
17452 (output): Disable call to output_master_parser, and give a try to
17453 a new skeleton handling system.
17454 (guards_output, actions_output): No longer static.
17455 (token_definitions_output, get_lines_number): No longer static.
17456
17457 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17458
17459 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17460 parse-skel.y.
17461
17462 * src/parse-skel.y: New file.
17463 * src/scan-skel.l: New file.
17464
17465 2001-12-29 Akim Demaille <akim@epita.fr>
17466
17467 %name-prefix is broken.
17468
17469 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
17470 Adjust all dependencies.
17471 * tests/headers.at (export YYLTYPE): Strengthen this test: use
17472 %name-prefix.
17473
17474 Renaming yylval but not yylloc is not consistent. Now we do.
17475
17476 * src/bison.simple: Prefix yylloc if used.
17477 * doc/bison.texinfo (Decl Summary): Document that.
17478
17479 2001-12-29 Akim Demaille <akim@epita.fr>
17480
17481 * doc/bison.texinfo: Promote `%long-directive' over
17482 `%long_directive'.
17483 Remove all references to fixed-output-files, yacc is enough.
17484
17485 2001-12-29 Akim Demaille <akim@epita.fr>
17486
17487 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
17488 user prologue. These are defaults.
17489 * tests/actions.at (Mid-rule actions): Make sure the user can
17490 define YYDEBUG and YYERROR_VERBOSE.
17491
17492 2001-12-29 Akim Demaille <akim@epita.fr>
17493
17494 * src/output.c (header_output): Don't forget to export YYLTYPE and
17495 yylloc.
17496 * tests/headers.at (export YYLTYPE): New, make sure it does.
17497 * tests/regression.at (%union and --defines, Invalid CPP headers):
17498 Move to...
17499 * tests/headers.at: here.
17500
17501 2001-12-29 Akim Demaille <akim@epita.fr>
17502
17503 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
17504
17505 2001-12-29 Akim Demaille <akim@epita.fr>
17506
17507 * tests/actions.at (Mid-rule actions): Output on a single line
17508 instead of several.
17509
17510 2001-12-29 Akim Demaille <akim@epita.fr>
17511
17512 * doc/bison.texinfo: Formatting changes.
17513
17514 2001-12-29 Akim Demaille <akim@epita.fr>
17515
17516 Don't store the token defs in a muscle, just be ready to output it
17517 on command. Now possible via `symbols'. Fixes a memory leak.
17518
17519 * src/output.c (token_definitions_output): New.
17520 (output_parser, header_output): Use it.
17521 * src/reader.c (symbols_save): Remove.
17522
17523 2001-12-29 Akim Demaille <akim@epita.fr>
17524
17525 * src/bison.simple: Do not provide a default for YYSTYPE and
17526 YYLTYPE before the user's prologue. Otherwise it's hardly... a
17527 default.
17528
17529 2001-12-29 Akim Demaille <akim@epita.fr>
17530
17531 Mid-rule actions are simply... ignored!
17532
17533 * src/reader.c (readgram): Be sure to attach mid-rule actions to
17534 the empty-rule associated to the dummy symbol, not to the host
17535 rule.
17536 * tests/actions.at (Mid-rule actions): New.
17537
17538 2001-12-29 Akim Demaille <akim@epita.fr>
17539
17540 Memory leak.
17541
17542 * src/reader.c (reader): Free grammar.
17543
17544 2001-12-29 Akim Demaille <akim@epita.fr>
17545
17546 Memory leak.
17547
17548 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
17549 since it allocates it for each state, although only one is needed.
17550 (allocate_storage): Do it here.
17551
17552 2001-12-29 Akim Demaille <akim@epita.fr>
17553
17554 * src/options.h, src/options.c (create_long_option_table): Rename
17555 as...
17556 (long_option_table_new): this, with a clearer prototype.
17557 (percent_table): Remove, unused,
17558 * src/getargs.c (getargs): Adjust.
17559
17560 2001-12-29 Akim Demaille <akim@epita.fr>
17561
17562 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
17563 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
17564 as states.
17565
17566 2001-12-29 Akim Demaille <akim@epita.fr>
17567
17568 * src/lalr.c (build_relations): Rename `states' as `states1'.
17569 Sorry, I don't understand exactly what it is, no better name...
17570
17571 2001-12-29 Akim Demaille <akim@epita.fr>
17572
17573 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
17574 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
17575 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
17576 as rules.
17577
17578 2001-12-29 Akim Demaille <akim@epita.fr>
17579
17580 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
17581 ago.
17582
17583 2001-12-29 Akim Demaille <akim@epita.fr>
17584
17585 * src/reader.c, src/reader.h (user_toknums): Remove.
17586 Adjust all users to use symbols[i]->user_token_number.
17587
17588 2001-12-29 Akim Demaille <akim@epita.fr>
17589
17590 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
17591 Adjust all users to use symbols[i]->prec or ->assoc.
17592
17593 2001-12-29 Akim Demaille <akim@epita.fr>
17594
17595 * src/reader.c, src/reader.h (tags): Remove.
17596 Adjust all users to use symbols[i]->tag.
17597
17598 2001-12-29 Akim Demaille <akim@epita.fr>
17599
17600 * src/gram.h, src/gram.c (symbols): New, similar to state_table
17601 and rule_table.
17602 * src/reader.c (packsymbols): Fill this table.
17603 Drop sprec.
17604 * src/conflicts.c (resolve_sr_conflict): Adjust.
17605 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
17606 single table.
17607 Use symbols[i]->tag instead of tags[i].
17608
17609 2001-12-29 Akim Demaille <akim@epita.fr>
17610
17611 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
17612 In addition, put a comment in there, to replace...
17613 * tests/regression.at (%union and C comments): Remove.
17614
17615 2001-12-29 Akim Demaille <akim@epita.fr>
17616
17617 * tests/regression.at (Web2c Actions): Blindly move the actual
17618 output as expected output. The contents *seem* right to me, but I
17619 can't pretend reading perfectly parser tables... Nonetheless, all
17620 the other tests pass correctly, the table look OK, even though the
17621 presence of `$axiom' is to be noted: AFAICS it is useless (but
17622 harmless).
17623
17624 2001-12-29 Akim Demaille <akim@epita.fr>
17625
17626 * src/reader.c (readgram): Don't add the rule 0 if there were no
17627 rules read. In other words, add it _after_ having performed
17628 grammar sanity checks.
17629 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
17630
17631 2001-12-29 Akim Demaille <akim@epita.fr>
17632
17633 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
17634 visible, and some states have now a different number.
17635
17636 2001-12-29 Akim Demaille <akim@epita.fr>
17637
17638 * src/reader.c (readgram): Bind the initial rule's lineno to that
17639 of the first rule.
17640 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
17641 (Solved SR Conflicts): Adjust rule 0's line number.
17642
17643 2001-12-29 Akim Demaille <akim@epita.fr>
17644
17645 Fix the `GAWK Grammar' failure.
17646
17647 * src/LR0.c (final_state): Initialize to -1 so that we do compute
17648 the reductions of the first state which was mistakenly confused
17649 with the final state because precisely final_state was initialized
17650 to 0.
17651 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
17652 now noticed by Bison.
17653 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
17654 have a reduction on $default.
17655
17656 2001-12-29 Akim Demaille <akim@epita.fr>
17657
17658 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
17659 rule line numbers.
17660 * src/closure.c (print_closure): Likewise.
17661 * src/derives.c (print_derives): Likewise.
17662 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
17663 now.
17664
17665 2001-12-29 Akim Demaille <akim@epita.fr>
17666
17667 * src/lalr.c (lookaheads_print): New.
17668 (lalr): Call it when --trace-flag.
17669 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
17670 are dumped.
17671
17672 2001-12-29 Akim Demaille <akim@epita.fr>
17673
17674 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
17675 when walking through ritem, even via rule->rhs.
17676 * src/reduce.c (dump_grammar, useful_production, reduce_output)
17677 (useful_production, useless_nonterminals): Likewise.
17678 (reduce_grammar_tables): Likewise, plus update nritems.
17679 * src/nullable.c (set_nullable): Likewise.
17680 * src/lalr.c (build_relations): Likewise.
17681 * tests/sets.at (Nullable): Adjust.
17682 Fortunately, now, the $axiom is no longer nullable.
17683
17684 2001-12-29 Akim Demaille <akim@epita.fr>
17685
17686 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
17687 the 0-sentinel.
17688 * src/gram.c (ritem_longest_rhs): Likewise.
17689 * src/reduce.c (nonterminals_reduce): Likewise.
17690 * src/print_graph.c (print_graph): Likewise.
17691 * src/output.c (output_rule_data): Likewise.
17692 * src/nullable.c (set_nullable): Likewise.
17693
17694 2001-12-29 Akim Demaille <akim@epita.fr>
17695
17696 * src/output.c: Comment changes.
17697
17698 2001-12-27 Paul Eggert <eggert@twinsun.com>
17699
17700 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
17701 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
17702 Sparc, as they were causing more porting problems than the
17703 (minor) performance improvement was worth.
17704
17705 Also, catch up with 1.31's YYSTD.
17706
17707 2001-12-27 Akim Demaille <akim@epita.fr>
17708
17709 * src/output.c (output_gram): Rely on nritems, not the
17710 0-sentinel. See below.
17711 Use -1 as separator, not 0.
17712 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
17713 Rely on -1 as separator in yyrhs, instead of 0.
17714 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
17715 twice `Now at end of input', therefore there are two lines less to
17716 expect.
17717
17718 2001-12-27 Akim Demaille <akim@epita.fr>
17719
17720 * tests/regression.at (Unresolved SR Conflicts):
17721 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
17722 below.
17723
17724 2001-12-27 Akim Demaille <akim@epita.fr>
17725
17726 * src/LR0.c (new_state): Recognize the final state by the fact it
17727 is reached by eoftoken.
17728 (insert_start_shifting_state, insert_eof_shifting_state)
17729 (insert_accepting_state, augment_automaton): Remove, since now
17730 these states are automatically computed from the initial state.
17731 (generate_states): Adjust.
17732 * src/print.c: When reporting a rule number to the user, substract
17733 1, so that the axiom rule is rule 0, and the first user rule is 1.
17734 * src/reduce.c: Likewise.
17735 * src/print_graph.c (print_core): For the time being, just as for
17736 the report, depend upon --trace-flags to dump the full set of
17737 items.
17738 * src/reader.c (readgram): Once the grammar read, insert the rule
17739 0: `$axiom: START-SYMBOL $'.
17740 * tests/set.at: Adjust: rule 0 is now displayed, and since the
17741 number of the states has changed (the final state is no longer
17742 necessarily the last), catch up.
17743
17744 2001-12-27 Akim Demaille <akim@epita.fr>
17745
17746 Try to make the use of the eoftoken valid. Given that its value
17747 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
17748 is used instead of > 0 where appropriate, (ii), depend upon nritems
17749 instead of the 0-sentinel.
17750
17751 * src/gram.h, src/gram.c (nritems): New.
17752 Expected to be duplication of nitems, but for the time being...
17753 * src/reader.c (packgram): Assert nritems and nitems are equal.
17754 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
17755 * src/closure.c (print_closure, print_fderives): Likewise.
17756 * src/gram.c (ritem_print): Likewise.
17757 * src/print.c (print_core, print_grammar): Likewise.
17758 * src/print_graph.c: Likewise.
17759
17760 2001-12-27 Akim Demaille <akim@epita.fr>
17761
17762 * src/main.c (main): If there are complains after grammar
17763 reductions, then output the report anyway if requested, then die.
17764 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
17765 * src/reader.c (eoftoken): New.
17766 (parse_token_decl): If the token being defined has value `0', it
17767 is the eoftoken.
17768 (packsymbols): No longer hack `tags' to insert `$' by hand.
17769 Be sure to preserve the value of the eoftoken.
17770 (reader): Make sure eoftoken is defined.
17771 Initialize nsyms to 0: now eoftoken is created just like the others.
17772 * src/print.c (print_grammar): Don't special case the eof token.
17773 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17774 lie anyway, albeit pleasant.
17775 * tests/calc.at: Exercise error messages with eoftoken.
17776 Change the grammar so that empty input is invalid.
17777 Adjust expectations.
17778 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
17779
17780 2001-12-27 Akim Demaille <akim@epita.fr>
17781
17782 * configure.in: Check the protos of strchr ans strspn.
17783 Replace strchr if needed.
17784 * src/system.h: Provide the protos of strchr, strspn and memchr if
17785 missing.
17786 * lib/strchr.c: New.
17787 * src/reader.c (symbols_save): Use strchr.
17788
17789 2001-12-27 Akim Demaille <akim@epita.fr>
17790
17791 * src/print.c, src/print_graph.c (escape): New.
17792 Use it to quote the TAGS outputs.
17793 * src/print_graph.c (print_state): Now errors are in red, and
17794 reductions in green.
17795 Prefer high to wide: output the state number on a line of its own.
17796
17797 2001-12-27 Akim Demaille <akim@epita.fr>
17798
17799 * src/state.h, src/state.c (reductions_new): New.
17800 * src/LR0.c (set_state_table): Let all the states have a
17801 `reductions', even if reduced to 0.
17802 (save_reductions): Adjust.
17803 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
17804 * src/print.c (print_reductions, print_actions): Adjust.
17805 * src/output.c (action_row): Adjust.
17806
17807 2001-12-27 Akim Demaille <akim@epita.fr>
17808
17809 * src/state.h, src/state.c (errs_new, errs_dup): New.
17810 * src/LR0.c (set_state_table): Let all the states have an errs,
17811 even if reduced to 0.
17812 * src/print.c (print_errs, print_reductions): Adjust.
17813 * src/output.c (output_actions, action_row): Adjust.
17814 * src/conflicts.c (resolve_sr_conflict): Adjust.
17815
17816 2001-12-27 Akim Demaille <akim@epita.fr>
17817
17818 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
17819
17820 2001-12-27 Akim Demaille <akim@epita.fr>
17821
17822 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
17823 * src/print.c: here.
17824 (lookaheadset, shiftset): New, used as additional storage by
17825 print_reductions.
17826 (print_results): Adjust.
17827 (print_shifts, print_gotos, print_errs): New, extracted from...
17828 (print_actions): here.
17829 * src/print_graph.c (print_actions): Remove dead code.
17830
17831 2001-12-27 Akim Demaille <akim@epita.fr>
17832
17833 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
17834 `$n' and `@n'.
17835
17836 2001-12-27 Akim Demaille <akim@epita.fr>
17837
17838 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
17839 (build_relations): Adjust.
17840
17841 2001-12-27 Akim Demaille <akim@epita.fr>
17842
17843 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
17844 duplication.
17845
17846 2001-12-27 Akim Demaille <akim@epita.fr>
17847
17848 * src/reader.c (packgram): Catch nitems overflows.
17849
17850 2001-12-27 Akim Demaille <akim@epita.fr>
17851
17852 * src/files.c, src/files.h (guard_obstack): Remove.
17853 * src/output.c (output): Adjust.
17854 * src/reader.c (parse_braces): New, factoring...
17855 (copy_action, copy_guard): these two which are renamed as...
17856 (parse_action, parse_guard): these.
17857 As a voluntary consequence, using braces around guards is now
17858 mandatory.
17859
17860 2001-12-27 Akim Demaille <akim@epita.fr>
17861
17862 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
17863 * src/reader.c (symbol_list): `guard' and `guard_line' are new
17864 members.
17865 (symbol_list_new): Adjust.
17866 (copy_action): action_line is the first line, not the last.
17867 (copy_guard): Just as for actions, store the `action' only, not
17868 the switch/case/break flesh.
17869 Don't parse the user action that might follow the guard, let...
17870 (readgram): do it, i.e., now, there can be an action after a
17871 guard.
17872 In other words the guard is just explicitly optional.
17873 (packgram): Adjust.
17874 * src/output.c (guards_output): New.
17875 (output_parser): Call it when needed.
17876 (output): Also free the guard and attrs obstacks.
17877 * src/files.c, src/files.h (obstack_save): Remove.
17878 (output_files): Remove.
17879 As a result, if one needs the former `.act' file, using an
17880 appropriate skeleton which requires actions and guards is now
17881 required.
17882 * src/main.c (main): Adjust.
17883 * tests/semantic.at: New.
17884 * tests/regression.at: Use `input.y' as input file name.
17885 Avoid 8+3 problems by requiring input.c when the test needs the
17886 parser.
17887
17888 2001-12-27 Akim Demaille <akim@epita.fr>
17889
17890 * src/reader.c (symbol_list_new): Be sure to initialize all the
17891 fields.
17892
17893 2001-12-27 Akim Demaille <akim@epita.fr>
17894
17895 All the hacks using a final pseudo state are now useless.
17896
17897 * src/LR0.c (set_state_table): state_table holds exactly nstates.
17898 * src/lalr.c (nLA): New.
17899 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
17900 instead of lookaheadsp from the pseudo state (nstate + 1).
17901
17902 2001-12-27 Akim Demaille <akim@epita.fr>
17903
17904 * src/output.c (action_row, token_actions): Use a state_t instead
17905 of a integer, and nlookaheads instead of the following state's
17906 lookaheadsp.
17907
17908 2001-12-27 Akim Demaille <akim@epita.fr>
17909
17910 * src/conflicts.c (log_resolution, flush_shift)
17911 (resolve_sr_conflict, set_conflicts, solve_conflicts)
17912 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
17913 (conflicts_print, print_reductions): Use a state_t instead of an
17914 integer when referring to a state.
17915 As much as possible, depend upon nlookaheads, instead of the
17916 `lookaheadsp' member of the following state (since lookaheads of
17917 successive states are successive, the difference between state n + 1
17918 and n served as the number of lookaheads for state n).
17919 * src/lalr.c (add_lookback_edge): Likewise.
17920 * src/print.c (print_core, print_actions, print_state)
17921 (print_results): Likewise.
17922 * src/print_graph.c (print_core, print_actions, print_state)
17923 (print_graph): Likewise.
17924 * src/conflicts.h: Adjust.
17925
17926 2001-12-27 Akim Demaille <akim@epita.fr>
17927
17928 * src/bison.hairy: Formatting/comment changes.
17929 ANSIfy.
17930 Remove `register' indications.
17931 Add plenty of `static'.
17932
17933 2001-12-27 Akim Demaille <akim@epita.fr>
17934
17935 * src/output.c (prepare): Drop the muscle `ntbase' which
17936 duplicates ntokens.
17937 * src/bison.simple: Formatting/comment changes.
17938 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
17939 is an undocumented synonym.
17940
17941 2001-12-22 Akim Demaille <akim@epita.fr>
17942
17943 * src/output.c (output_table_data): Change the prototype to use
17944 `int' for array ranges: some invocations do pass an int, not a
17945 short.
17946 Reported by Wayne Green.
17947
17948 2001-12-22 Akim Demaille <akim@epita.fr>
17949
17950 Some actions of web2c.y are improperly triggered.
17951 Reported by Mike Castle.
17952
17953 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
17954 * tests/regression.at (Web2c): Rename as...
17955 (Web2c Report): this.
17956 (Web2c Actions): New.
17957
17958 2001-12-22 Akim Demaille <akim@epita.fr>
17959
17960 Reductions in web2c.y are improperly reported.
17961 Reported by Mike Castle.
17962
17963 * src/conflicts.c (print_reductions): Fix.
17964 * tests/regression.at (Web2c): New.
17965
17966 2001-12-18 Akim Demaille <akim@epita.fr>
17967
17968 Some host fail on `assert (!"foo")', which expands to
17969 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
17970 Reported by Nelson Beebee.
17971
17972 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
17973 `#define it_succeeded 0' and `assert (it_succeeded)'.
17974
17975 2001-12-17 Marc Autret <autret_m@epita.fr>
17976
17977 * src/bison.simple: Don't hard code the skeleton line and filename.
17978 * src/output.c (output_parser): Rename 'line' as 'output_line'.

17980
17981 2001-12-17 Paul Eggert <eggert@twinsun.com>
17982
17983 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
17984 YYDEBUG must be defined to a nonzero value.
17985
17986 * src/bison.simple (yytname): Do not assume that the user defines
17987 YYDEBUG to a properly parenthesized expression.
17988
17989 2001-12-17 Akim Demaille <akim@epita.fr>
17990
17991 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
17992 nlookaheads is a new member.
17993 Adjust all users.
17994 * src/lalr.h (nlookaheads): Remove this orphan declaration.
17995 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
17996 state.
17997
17998 2001-12-17 Akim Demaille <akim@epita.fr>
17999
18000 * src/files.h, src/files.c (open_files, close_files): Remove.
18001 * src/main.c (main): Don't open/close files, nor invoke lex_free,
18002 let...

18005 2001-12-17 Akim Demaille <akim@epita.fr>
18006

18012 (flush_reduce): New.
18013 (resolve_sr_conflict): Adjust.
18014
18015 2001-12-17 Akim Demaille <akim@epita.fr>
18016
18017 * src/output.c (output_obstack): Be static and rename as...
18018 (format_obstack): this, to avoid any confusion with files.c's
18019 output_obstack.
18020 * src/reader.h (muscle_obstack): Move to...
18021 * src/output.h: here, since it's defined in output.c.
18022
18023 2001-12-17 Akim Demaille <akim@epita.fr>
18024
18025 * src/output.c (action_row, save_column, default_goto)
18026 (sort_actions, matching_state, pack_vector): Better variable
18027 locality.
18028

18039 * src/conflicts.c (log_resolution): Output only if verbose_flag.
18040
18041 2001-12-16 Marc Autret <autret_m@epita.fr>
18042
18043 * src/output.c (actions_output): Fix. When we use %no-lines,
18044 there is one less line per action.
18045
18046 2001-12-16 Marc Autret <autret_m@epita.fr>
18047
18048 * src/bison.simple: Remove a useless #line directive.
18049 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18050 * src/output.c (get_lines_number): New.
18051 (output_parser): Adjust, now takes care about the lines of a
18052 output muscles.
18053 Fix line numbering.
18054 (actions_output): Computes the number of lines taken by actions.
18055 (output_master_parser): Insert new skeleton which is the name of
18056 the output parser file name.
18057
18058 2001-12-15 Marc Autret <autret_m@epita.fr>
18059

18063
18064 * src/output.c (output_gram): Keep track of the hairy one.
18065
18066 2001-12-15 Akim Demaille <akim@epita.fr>
18067
18068 Make `make distcheck' work.
18069
18070 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
18071 system.h which uses libgettext.h.
18072
18073 2001-12-15 Akim Demaille <akim@epita.fr>
18074
18075 * src/nullable.c (set_nullable): Useless rules must be skipped,
18076 otherwise, since we range over their symbols, we might look at a
18077 nonterminal which no longer ``exists'', i.e., it is not counted in
18078 `nvars', hence we overflow our arrays.
18079
18080 2001-12-15 Akim Demaille <akim@epita.fr>
18081
18082 The header can also be produced directly, without any obstack!
18083 Yahoo!
18084
18085 * src/files.c, src/files.h (defines_obstack): Remove.
18086 (compute_header_macro): Global.
18087 (defines_obstack_save): Remove.
18088 * src/reader.c (parse_union_decl): No longer output to
18089 defines_obstack: its content can be found in the `stype' muscle
18090 anyway.
18091 (output_token_translations): Merge into...
18092 (symbols_output): this.
18093 Rename as...
18094 (symbols_save): this.
18095 (reader): Adjust.
18096 * src/output.c (header_output): New.
18097 (output): Call it.
18098
18099 2001-12-15 Akim Demaille <akim@epita.fr>
18100
18101 * src/reader.c (parse_union_decl): Instead of handling two obstack
18102 simultaneously, use one to define the `stype' muscle, and use the
18103 value of the latter to fill defines_obstack.
18104 (copy_comment): Remove.
18105 (copy_comment2): Work for a single obstack.
18106 Rename as...
18107 (copy_comment): this.
18108
18109 2001-12-15 Akim Demaille <akim@epita.fr>
18110
18111 * src/lex.c, src/lex.h (xgetc): No longer static.
18112 * src/reader.c (parse_union_decl): Revamp.
18113
18114 2001-12-15 Akim Demaille <akim@epita.fr>
18115
18116 Still making progress in separating Bison into (i) input, (ii)
18117 process, (iii) output: now we can directly output the parser file
18118 without using table_obstack at all.
18119
18120 * src/files.c, src/files.h (table_obstack): Bye bye.
18121 (parser_file_name): New.
18122 * src/files.c (compute_output_file_names): Compute it.
18123 * src/output.c (actions_output, output_parser)
18124 (output_master_parser): To a file instead of an obstack.
18125
18126 2001-12-15 Akim Demaille <akim@epita.fr>
18127
18128 Attach actions to rules, instead of pre-outputting them to
18129 actions_obstack.
18130
18131 * src/gram.h (rule_t): action and action_line are new members.
18132 * src/reader.c (symbol_list): Likewise.
18133 (copy_action): Save the actions within the rule.
18134 (packgram): Save them in rule_table.
18135 * src/output.c (actions_output): New.
18136 (output_parser): Use it on `%%actions'.
18137 (output_rule_data): Don't free rule_table.
18138 (output): Do it.
18139 (prepare): Don't save the `action' muscle.
18140 * src/bison.simple: s/%%action/%%actions/.
18141
18142 2001-12-15 Akim Demaille <akim@epita.fr>
18143
18144 * src/reader.c (copy_action): When --yacc, don't append a `;'
18145 to the user action: let it fail if lacking.
18146 Suggested by Arnold Robbins and Tom Tromey.
18147
18148 2001-12-14 Akim Demaille <akim@epita.fr>
18149
18150 * src/lex.c (literalchar): Simply return the char you decoded, non
18151 longer mess around with obstacks and int pointers.
18152 Adjust all callers.
18153
18154 2001-12-14 Akim Demaille <akim@epita.fr>
18155
18156 * src/lex.c (literalchar): Don't escape the special characters,
18157 just decode them, and keep them as char (before, eol was output as
18158 the 2 char string `\n' etc.).
18159 * src/output.c (output_rule_data): Use quotearg to output the
18160 token strings.
18161
18162 2001-12-13 Paul Eggert <eggert@twinsun.com>
18163
18164 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
18165 Do not infringe on the global user namespace when using C++.
18166 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
18167 All uses of `fprintf' and `stderr' changed.
18168
18169 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
18170
18171 2001-12-13 Akim Demaille <akim@epita.fr>
18172
18173 The computation of nullable is broken: it doesn't handle empty
18174 RHS's properly.
18175
18176 * tests/torture.at (GNU AWK Grammar): New.
18177 * tests/sets.at (Nullable): New.
18178 * src/nullable.c (set_nullable): Instead of blindly looping over
18179 `ritems', loop over the rules, and then over their rhs's.
18180
18181 Work around Autotest bugs.
18182
18183 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
18184 frame, because Autotest understand lines starting with a `+' as
18185 traces from the shell. Then, they are not processed properly.
18186 Admittedly an Autotest bug, but we don't have time to wait for
18187 Autotest to catch up.
18188 * tests/regression.at (Broken Closure): Adjust to the new table
18189 frames.
18190 Move to...
18191 * tests/sets.at: here.
18192
18193 2001-12-13 Akim Demaille <akim@epita.fr>
18194
18195 * src/closure.c (closure): Use nrules instead of playing tricks
18196 with BITS_PER_WORD.
18197
18198 2001-12-13 Akim Demaille <akim@epita.fr>
18199
18200 * src/print.c (print_actions): Output the handling of `$' as the
18201 traces do: shifting the token EOF. Before EOF was treated as a
18202 nonterminal.
18203 * tests/regression.at: Adjust some tests.
18204 * src/print_graph.c (print_core): Complete the set of items via
18205 closure. The next-to-final and final states are still unsatisfying,
18206 but that's to be addressed elsewhere.
18207 No longer output the rule numbers, but do output the state number.
18208 A single loop for the shifts + gotos is enough, but picked a
18209 distinct color for each.
18210 (print_graph): Initialize and finalize closure.
18211
18212 2001-12-13 Akim Demaille <akim@epita.fr>
18213
18214 * src/reader.c (readgram): Remove dead code, an strip useless
18215 braces.
18216 (get_type): Remove, unused.
18217
18218 2001-12-12 Akim Demaille <akim@epita.fr>
18219
18220 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
18221 on that of lib/error.c.
18222
18223 2001-12-12 Akim Demaille <akim@epita.fr>
18224
18225 Some hosts don't like `/' in includes.
18226
18227 * src/system.h: Include libgettext.h without qualifying the path.
18228 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18229 $(top_srcdir).
18230
18231 2001-12-11 Marc Autret <autret_m@epita.fr>
18232
18233 * src/output.c (output_parser): Remove useless muscle.
18234
18235 2001-12-11 Marc Autret <autret_m@epita.fr>
18236
18237 * src/bison.simple: Remove #line just before %%epilogue. It
18238 is now handled in ...
18239 * src/reader.c (read_additionnal_code): Add the output of a
18240 #line for the epilogue.
18241
18242 2001-12-10 Marc Autret <autret_m@epita.fr>
18243
18244 * src/reader.c (copy_definition): Re-use CPP-outed code which
18245 replace precedent remove.
18246 * src/bison.simple: Remove #line before %%prologue because
18247 %%input-line is wrong at this time.
18248
18249 2001-12-10 Marc Autret <autret_m@epita.fr>
18250
18251 * src/reader.c (symbols_output): Clean up.
18252 * src/output.c (output_gram, output): Clean up.
18253
18254 2001-12-10 Akim Demaille <akim@epita.fr>
18255
18256 * src/lalr.c (initialize_lookaheads): New. Extracted from...
18257 * src/LR0.c (set_state_table): here.
18258 * src/lalr.c (lalr): Call it.
18259
18260 2001-12-10 Akim Demaille <akim@epita.fr>
18261
18262 * src/state.h (shifts): Remove the `number' member: shifts are
18263 attached to state, hence no longer need to be labelled with a
18264 state number.
18265
18266 2001-12-10 Akim Demaille <akim@epita.fr>
18267
18268 Now that states have a complete set of members, the linked list of
18269 shifts is useless: just fill directly the state's shifts member.
18270
18271 * src/state.h (shifts): Remove the `next' member.
18272 * src/LR0.c (first_state, last_state): Remove.
18273 Adjust the callers.
18274 (augment_automaton): Don't look for the shifts that must be added
18275 a shift on EOF: it is those of the state we looked for! But now,
18276 since shifts are attached, it is no longer needed to looking
18277 merely by its id: its number.
18278
18279 2001-12-10 Akim Demaille <akim@epita.fr>
18280
18281 * src/LR0.c (augment_automaton): Better variable locality.
18282 Remove an impossible branch: if there is a state corresponding to
18283 the start symbol being shifted, then there is shift for the start
18284 symbol from the initial state.
18285
18286 2001-12-10 Akim Demaille <akim@epita.fr>
18287
18288 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
18289 only when appropriate: when insert_start_shifting_state' is not
18290 invoked.
18291 * tests/regression.at (Rule Line Numbers): Adjust.
18292
18293 2001-12-10 Akim Demaille <akim@epita.fr>
18294
18295 * src/LR0.c (augment_automaton): Now that all states have shifts,
18296 merge the two cases addition shifts to the initial state.
18297
18298 2001-12-10 Akim Demaille <akim@epita.fr>
18299
18300 * src/lalr.c (set_state_table): Move to...
18301 * src/LR0.c: here.
18302 * src/lalr.c (lalr): Don't call it...
18303 * src/LR0.c (generate_states): do it.
18304 * src/LR0.h (first_state): Remove, only the table is used.
18305
18306 2001-12-10 Akim Demaille <akim@epita.fr>
18307
18308 * src/LR0.h (first_shift, first_reduction): Remove.
18309 * src/lalr.c: Don't use first_shift: find shifts through the
18310 states.
18311
18312 2001-12-10 Akim Demaille <akim@epita.fr>
18313
18314 * src/LR0.c: Attach shifts to states as soon as they are
18315 computed.
18316 * src/lalr.c (set_state_table): Instead of assigning shifts to
18317 state, just assert that the mapping was properly done.
18318
18319 2001-12-10 Akim Demaille <akim@epita.fr>
18320
18321 * src/LR0.c (insert_start_shift): Rename as...
18322 (insert_start_shifting_state): this.
18323 (insert_eof_shifting_state, insert_accepting_state): New.
18324 (augment_automaton): Adjust.
18325 Better locality of the variables.
18326 When looking if the start_symbol is shifted from the initial
18327 state, using `while (... symbol != start_symbol ...)' sounds
18328 better than `while (... symbol < start_symbol ...)': If fail
18329 to see how the order between symbols could be relevant!
18330
18331 2001-12-10 Akim Demaille <akim@epita.fr>
18332
18333 * src/getargs.h: Don't declare `spec_name_prefix' and
18334 `spec_file_prefix', declared by src/files.h.
18335 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18336 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
18337 * src/output.c (prepare): Adjust.
18338 * src/reader.c (symbols_output): Likewise.
18339 * src/vmsgetargs.c: Vaguely adjust, but who cares?
18340
18341 2001-12-10 Akim Demaille <akim@epita.fr>
18342
18343 * src/muscle_tab.c (muscle_init): NULL is a better default than
18344 `"0"'.
18345
18346 2001-12-10 Akim Demaille <akim@epita.fr>
18347
18348 * src/reader.c (reader): Calling symbols_output once is enough.
18349
18350 2001-12-10 Akim Demaille <akim@epita.fr>
18351
18352 Now that states have a complete set of members, the linked list of
18353 reductions is useless: just fill directly the state's reductions
18354 member.
18355
18356 * src/state.h (struct reductions): Remove member `number' and
18357 `next'.
18358 * src/LR0.c (first_reduction, last_reduction): Remove.
18359 (save_reductions): Don't link the new reductions, store them in
18360 this_state.
18361 * src/lalr.c (set_state_table): No need to attach reductions to
18362 states, it's already done.
18363 * src/output.c (output_actions): No longer free the shifts, then
18364 the reductions, then the states: free all the states and their
18365 members.
18366
18367 2001-12-10 Akim Demaille <akim@epita.fr>
18368
18369 * src/options.c (OPTN, DRTV, BOTH): New.
18370 (option_table): Use them.
18371
18372 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18373 the job of system.h.
18374 * src/options.c: Don't include stdio.h and xalloc.h for the same
18375 reasons.
18376
18377 2001-12-10 Akim Demaille <akim@epita.fr>
18378
18379 * src/output.c (output, prepare): Make sure the values of the
18380 muscles `action' and `prologue' are 0-terminated.
18381
18382 2001-12-10 Akim Demaille <akim@epita.fr>
18383
18384 Clean up GCC warnings.
18385
18386 * src/reader.c (copy_action): `buf' is not used.
18387 (parse_skel_decl): Be static.
18388 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18389 * src/options.h (create_long_option_table): Have a real prototype.
18390 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18391 (hash_delete_at): Return const void *.
18392 Adjust casts to preserve the const.
18393
18394 2001-12-10 Akim Demaille <akim@epita.fr>
18395
18396 * configure.in: Require 2.52g.
18397 M4 is not needed, but AUTOM4TE is.
18398 * m4/m4.m4: Remove.
18399 * tests/Makefile.am: Adjust.
18400
18401 2001-12-10 Akim Demaille <akim@epita.fr>
18402
18403 One structure for states is enough, even though theoretically
18404 there are LR(0) states and LALR(1) states.
18405
18406 * src/lalr.h (state_t): Remove.
18407 (state_table): Be state_t **, not state_t *.
18408 * src/state.h (core, CORE_ALLOC): Rename as...
18409 (state_t, STATE_ALLOC): this.
18410 Add the LALR(1) members: shifts, reductions, errs.
18411 * src/LR0.c (state_table): Rename as...
18412 (state_hash): this, to avoid name clashes with the global
18413 `state_table'.
18414 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18415 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18416
18417 2001-12-10 Akim Demaille <akim@epita.fr>
18418
18419 Bison dumps core on bash.y.
18420 Reported by Pascal Bart.
18421
18422 * src/warshall.c (bitmatrix_print): New.
18423 (TC): Use it.
18424 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18425 j must be the outer loop.
18426 * tests/regression.at (Broken Closure): New.
18427
18428 2001-12-05 Akim Demaille <akim@epita.fr>
18429
18430 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18431 its argument.
18432 Reported by Peter Hamorsky.
18433
18434 2001-12-05 Akim Demaille <akim@epita.fr>
18435
18436 * src/conflicts.c (err_table): Remove.
18437 (resolve_sr_conflict): Adjust.
18438 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18439 Rename as...
18440 (state_t.reductions, state_t.shifts): this.
18441
18442 2001-12-05 Akim Demaille <akim@epita.fr>
18443
18444 * src/reduce.c (reduce_grammar_tables): No longer disable the
18445 removal of useless rules via CPP but via `if (0)', so that the
18446 compiler still check the code is valid.
18447 For instance, it should have noticed `rline' no longer exists: use
18448 the `line' member of rule_t.
18449 * src/gram.c (dummy, rline): Remove, unused.
18450
18451 2001-12-05 Akim Demaille <akim@epita.fr>
18452
18453 * src/output.c (pack_vector): Use assert, not berror.
18454 * src/main.c (berror): Remove, unused.
18455
18456 2001-12-05 Akim Demaille <akim@epita.fr>
18457
18458 New experimental feature: if --verbose --trace output all the
18459 items of a state, not only its kernel.
18460
18461 * src/print.c (print_core): If `trace_flag', then invoke closure
18462 before outputting the items of the state (print_core is no longer
18463 a correct name them).
18464 (print_results): Invoke new_closure/free_closure if needed.
18465
18466 2001-12-05 Akim Demaille <akim@epita.fr>
18467
18468 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18469 * src/closure.c, src/closure.h (itemsetsize): Rename as...
18470 (nitemset): for consistency with the rest of the project.
18471
18472 2001-12-05 Akim Demaille <akim@epita.fr>
18473
18474 * src/closure.c (print_closure): Improve.
18475 (closure): Use it for printing input and output.
18476
18477 2001-12-05 Akim Demaille <akim@epita.fr>
18478
18479 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
18480 indexed by nonterminals.
18481
18482 2001-12-05 Akim Demaille <akim@epita.fr>
18483
18484 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
18485 what it was!).
18486 * src/warshall.h: Remove accidental duplication of the content.
18487
18488 2001-12-05 Akim Demaille <akim@epita.fr>
18489
18490 * src/closure.c (set_fderives): De-obfuscate.
18491
18492 2001-12-05 Akim Demaille <akim@epita.fr>
18493
18494 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
18495
18496 2001-12-05 Akim Demaille <akim@epita.fr>
18497
18498 * src/closure.c (set_firsts): De-obfuscate.
18499
18500 2001-12-05 Akim Demaille <akim@epita.fr>
18501
18502 * src/output.c (action_row): De-obfuscate
18503 using the good o' techniques: arrays not pointers, variable
18504 locality, BITISSET, RESETBIT etc.
18505
18506 2001-12-05 Akim Demaille <akim@epita.fr>
18507
18508 Pessimize the code to simplify it: from now on, all the states
18509 have a valid SHIFTS, which NSHIFTS is possibly 0.
18510
18511 * src/LR0.c (shifts_new): Be global and move to..
18512 * src/state.c, src/state.h: here.
18513 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
18514 * src/print_graph: Adjust.
18515
18516 2001-12-05 Akim Demaille <akim@epita.fr>
18517
18518 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
18519 * src/conflicts.c: Use it.
18520 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
18521 incorrectly ``simplified''.
18522
18523 2001-12-05 Akim Demaille <akim@epita.fr>
18524
18525 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
18526 using the good o' techniques: arrays not pointers, variable
18527 locality, BITISSET, RESETBIT etc.
18528
18529 2001-12-05 Akim Demaille <akim@epita.fr>
18530
18531 * src/state.h (SHIFT_SYMBOL): New.
18532 * src/conflicts.c: Use it to deobfuscate.
18533
18534 2001-12-05 Akim Demaille <akim@epita.fr>
18535
18536 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
18537 (print_reductions): De-obfuscate using the good o' techniques:
18538 arrays not pointers, variable locality, BITISSET.
18539
18540 2001-12-05 Akim Demaille <akim@epita.fr>
18541
18542 * src/conflicts.c (print_reductions): Arrays, not pointers.
18543 Use BITISSET.
18544
18545 2001-12-05 Akim Demaille <akim@epita.fr>
18546
18547 * src/conflicts.c (print_reductions): Pessimize, but clarify.
18548
18549 2001-12-05 Akim Demaille <akim@epita.fr>
18550
18551 * src/conflicts.c (print_reductions): Improve variable locality.
18552
18553 2001-12-05 Akim Demaille <akim@epita.fr>
18554
18555 * src/conflicts.c (print_reductions): Pessimize, but clarify.
18556
18557 2001-12-05 Akim Demaille <akim@epita.fr>
18558
18559 * src/conflicts.c (print_reductions): Improve variable locality.
18560
18561 2001-12-05 Akim Demaille <akim@epita.fr>
18562
18563 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
18564 * src/lalr.c: Use them.
18565
18566 2001-12-05 Akim Demaille <akim@epita.fr>
18567
18568 * src/LR0.c (augment_automaton): Formatting changes.
18569 Better variable locality.
18570
18571 2001-12-05 Akim Demaille <akim@epita.fr>
18572
18573 * src/lalr.c (matrix_print): New.
18574 (transpose): Use it.
18575 Use arrays instead of pointers.
18576
18577 2001-12-05 Akim Demaille <akim@epita.fr>
18578
18579 * src/lalr.c (maxrhs): Move to...
18580 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
18581 * src/lalr.c (build_relations): Adjust.
18582
18583 2001-12-05 Akim Demaille <akim@epita.fr>
18584
18585 * src/lalr.c (transpose): Free the memory allocated to the
18586 argument, as it is replaced by the results by the unique caller.
18587 (build_relations): Merely invoke transpose: it handles the memory
18588 deallocation.
18589 Improve variable locality.
18590 Avoid variables used as mere abbreviations.
18591 (compute_lookaheads): Use arrays instead of pointers.
18592
18593 2001-12-05 Akim Demaille <akim@epita.fr>
18594
18595 * src/lalr.c (initialize_F): Improve variable locality.
18596 Avoid variables used as mere abbreviations.
18597
18598 2001-12-05 Akim Demaille <akim@epita.fr>
18599
18600 * src/derives.c (print_derives): Display the ruleno.
18601 * src/lalr.c (initialize_F, transpose): Better variable locality
18602 to improve readability.
18603 Avoid variables used as mere abbreviations.
18604
18605 2001-12-05 Akim Demaille <akim@epita.fr>
18606
18607 * src/lalr.c (traverse): Use arrays instead of pointers.
18608
18609 2001-12-05 Akim Demaille <akim@epita.fr>
18610
18611 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
18612 the handling of squeue.
18613 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18614
18615 2001-12-05 Akim Demaille <akim@epita.fr>
18616
18617 Because useless nonterminals are now kept alive (instead of being
18618 `destroyed'), we now sometimes examine them, and store information
18619 related to them. Hence we need to know their number, and adjust
18620 memory allocations.
18621
18622 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18623 static.
18624 * src/LR0.c (allocate_itemsets): The memory allocated to
18625 `symbol_count' was used for two different purpose: once to count
18626 the number of occurrences of each symbol, and later reassigned to
18627 `shift_symbol', containing the symbol that can be shifted from a
18628 given state.
18629 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18630 only, and...
18631 (new_itemsets): Allocate `shift_symbol' here.
18632 (allocate_itemsets): symbol_count includes useless nonterminals.
18633 Make room for them.
18634 (free_storage): Use `free', not `XFREE', for pointers that cannot
18635 be null.
18636
18637 2001-12-05 Akim Demaille <akim@epita.fr>
18638
18639 * src/nullable.c (set_nullable): Deobfuscate the handling of
18640 ritem.
18641 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18642
18643 2001-12-05 Akim Demaille <akim@epita.fr>
18644
18645 * src/gram.c, src/gram.h (ritem_print): New.
18646 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
18647 (This useless function was defined only to work around VMS linkers
18648 that can't handle compilation units with variables only).
18649 * src/reduce.c (dump_grammar): Use it to trace the construction of
18650 ritem.
18651
18652 2001-12-04 Paul Eggert <eggert@twinsun.com>
18653
18654 * src/bison.simple (union yyalloc): Change member names
18655 to be the same as the stack names.
18656 (yyparse): yyptr is now union yyalloc *, not char *.
18657 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
18658 and may generate better code on some machines.
18659 (yystpcpy): Use prototype if __STDC__ is defined, not just
18660 if __cplusplus is defined.
18661
18662 2001-11-30 Akim Demaille <akim@epita.fr>
18663
18664 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
18665 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
18666 Gettext doesn't compile cleanly, and dies with -Werror.
18667 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
18668 Include WARNING_CFLAGS here.
18669 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
18670 before being defined.
18671
18672 2001-11-27 Paul Eggert <eggert@twinsun.com>
18673
18674 * lib/quotearg.h (quotearg_n, quotearg_n_style):
18675 First arg is int, not unsigned.
18676 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
18677 (SIZE_MAX, UINT_MAX): New macros.
18678 (quotearg_n_options): Abort if N is negative.
18679 Avoid overflow check on hosts where size_t is 64 bits and int
18680 is 32 bits, as overflow is impossible there.
18681 Fix off-by-one typo that caused unnecessary reallocation.
18682
18683 2001-11-29 Paul Eggert <eggert@twinsun.com>
18684
18685 Name space cleanup in generated parser.

18687 * doc/bison.texinfo (Bison Parser): Discuss system headers
18688 and their effect on the user name space.
18689
18690 * src/bison.simple:
18691 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
18692 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
18693 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
18694
18695 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
18696 on user names when possible.
18697
18698 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
18699 Simplify test for whather <alloca.h> exists.
18700
18701 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
18702
18703 (<stdio.h>): Include if YYDEBUG.
18704
18705 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
18706 ! defined (yyoverflow) && ! defined (yymemcpy).
18707
18708 (yymemcpy, yyparse): Rename local variables as needed so that
18709 they all begin with 'yy'.
18710
18711 (yystrlen, yystpcpy): New functions.
18712
18713 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
18714 All uses changed.
18715
18716 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
18717 instead of relying on string.h functions. Use YYSTACK_ALLOC
18718 and YYSTACK_FREE instead of malloc and free.
18719
18720 2001-11-30 Akim Demaille <akim@epita.fr>
18721
18722 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
18723 before their first uses.
18724 (YYBISON, YYPURE): Move to the top of the output.
18725

18728 * tests/reduce.at (Useless Nonterminals): Fix.
18729
18730 2001-11-30 Akim Demaille <akim@epita.fr>
18731
18732 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
18733 if body instead of `;' to pacify GCC's warnings.
18734
18735 2001-11-30 Akim Demaille <akim@epita.fr>
18736
18737 Instead of mapping the LHS of unused rules to -1, keep the LHS
18738 valid, but flag the rules as invalid.
18739
18740 * src/gram.h (rule_t): `useful' is a new member.
18741 * src/print.c (print_grammar): Adjust.
18742 * src/derives.c (set_derives): Likewise.
18743 * src/reader.c (packgram, reduce_output): Likewise.
18744 * src/reduce.c (reduce_grammar_tables): Likewise.

18748
18749 * src/reduce.c (reduce_output): Formatting changes.
18750 * src/print.c (print_results, print_grammar): Likewise.
18751 * tests/regression.at (Rule Line Numbers)
18752 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
18753
18754 2001-11-30 Akim Demaille <akim@epita.fr>
18755
18756 * src/reduce.c (nonterminals_reduce): Instead of throwing away
18757 useless nonterminals, move them at the end of the symbol arrays.
18758 (reduce_output): Adjust.
18759 * tests/reduce.at (Useless Nonterminals): Adjust.
18760
18761 2001-11-30 Akim Demaille <akim@epita.fr>
18762
18763 * src/reduce.c: Various comment/formatting changes.
18764 (nonterminals_reduce): New, extracted from...
18765 (reduce_grammar_tables): here.
18766 (reduce_grammar): Call nonterminals_reduce.
18767
18768 2001-11-29 Paul Eggert <eggert@twinsun.com>
18769
18770 * src/bison.simple (YYSTACK_REALLOC): Remove.
18771 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
18772 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
18773 New macros.
18774 (union yyalloc): New type.
18775 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
18776 an arbitrary restriction on hosts where size_t is wider than int.
18777
18778 (yyparse): Don't dump core if alloca or malloc fails; instead, report
18779 a parser stack overflow. Allocate just one block of memory for all
18780 three stacks, instead of allocating three blocks; this typically is
18781 faster and reduces fragmentation.
18782
18783 Do not limit the number of items in the stack to a value that fits
18784 in 'int', as this is an arbitrary limit on hosts with 64-bit
18785 size_t and 32-bit int.
18786
18787 2001-11-29 Marc Autret <autret_m@epita.fr>
18788
18789 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

18825 2001-11-28 Marc Autret <autret_m@epita.fr>
18826
18827 * src/bison.simple: Fix debug.

18846
18847 * src/closure.c (closure): No longer optimize the special case
18848 where all the bits of `ruleset[r]' are set to 0, to make the code
18849 clearer.
18850
18851 2001-11-28 Akim Demaille <akim@epita.fr>
18852
18853 * src/closure.c (closure): `r' and `c' are new variables, used to
18854 de-obfuscate accesses to RULESET and CORE.

18933
18934 2001-11-26 Akim Demaille <akim@epita.fr>
18935
18936 * src/LR0.c (allocate_itemsets): kernel_size contains ints, not

18938
18939 2001-11-26 Akim Demaille <akim@epita.fr>
18940
18941 * src/complain.c, src/complain.h (error): Remove, provided by

18983
18984 2001-11-23 Akim Demaille <akim@epita.fr>
18985
18986 Attaching lineno to buckets is stupid, since only one copy of each

19212 * tests/calc.at, tests/output.at, tests/regression.at,
19213 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
19214 now the tests are run in private dirs, therefore AC_CLEANUP and

19217 use abs. path to find config.h.
19218 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

19224

19240 braces to pacify GCC's warnings for `if () if () {} else {}'.
19241 * src/lex.c (parse_percent_token): Replace equal_offset with
19242 arg_offset.

19342 with yyltype/YYLTYPE. This allows inclusion of the generated

20643 * src/reader.c (read_declarations): Adjust.
20644 * src/files.c (open_files): Don't call `compute_base_names', don't
20645 compute `attrsfile' since they depend upon data which might be
20646 *in* the input file now.
20647 (output_files): Do it here.
20648 * src/output.c (output_headers): Document the fact that this patch

20751 2000-12-19 Akim Demaille <akim@epita.fr>
20752
20753 * src/files.c (open_files): Yipee! We no longer need all the code
20754 looking for `/tmp' since we have no tmp file.
20755
20756 2000-12-19 Akim Demaille <akim@epita.fr>
20757
20758 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
20759 New macros.

20786 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
20787 prevents type checking.
20788 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
20789 cast the value to (void *): assigning a `foo *' to a `void *'
20790 variable is valid.
20791 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
20792 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
20793 append characters.

20836 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
20837 argument `data' for consistency with the prototypes.
20838 Qualify it `const'.
20839 (obstack_copy, obstack_copy0): Rename the second argument as
20840 `address' for consistency. Qualify it `const'.
20841 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)

20843 `const' their input argument (`data' or `address').
20844 Adjust the corresponding macros to include `const' in casts.
20845
20846 2000-11-03 Akim Demaille <akim@epita.fr>
20847
20848 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

20851
20852 2000-11-03 Akim Demaille <akim@epita.fr>
20853
20854 For some reason, this was not applied.
20855
20856 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

20870 (output_files): this.
20871 Use `obstack_save'.
20872 * src/main.c (main): Don't use `atexit' to register `done', since
20873 it no longer has to remove tmp files, just call `output_files'
20874 when there are no errors.

20897 2000-11-01 Akim Demaille <akim@epita.fr>
20898

20908
20909 Introduce obstacks.

20945
20946 * src/reader.c (copy_comment2): Expect the input stream to be on
20947 the `/' which is suspected to open a comment, instead of being
20948 called after `//' or `/*' was read.
20949 (copy_comment, copy_definition, parse_union_decl, copy_action)
20950 (copy_guard): Adjust.
20951
20952 2000-10-16 Akim Demaille <akim@epita.fr>
20953
20954 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
20955 `read_signed_integer'.
20956
20957 2000-10-16 Akim Demaille <akim@epita.fr>
20958
20959 * src/reader.c (copy_dollar): New function.

20977
20978 2000-10-04 Akim Demaille <akim@epita.fr>
20979
20980 When a literal string is used to define two different tokens,
20981 `bison -v' segfaults.
20982 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
20983

20992 of `buffer'.
20993 From Neil Booth.
20994
20995 2000-10-02 Paul Eggert <eggert@twinsun.com>
20996
20997 * bison.s1 (yyparse): Assign the default value
20998 unconditionally, to avoid a GCC warning and make the parser a
20999 tad smaller.
21000
21001 2000-10-02 Akim Demaille <akim@epita.fr>
21002
21003 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
21004 options.
21005
21006 2000-10-02 Akim Demaille <akim@epita.fr>
21007
21008 * src/derives.c, src/print.c, src/reduce.c: To ease the
21009 translation, move some `\n' out of the translated strings.
21010
21011 2000-10-02 Akim Demaille <akim@epita.fr>
21012
21013 The location tracking mechanism is precious for parse error
21014 messages. Nevertheless, it is enabled only when `@n' is used in
21015 the grammar, which is a different issue (you can use it in error
21016 message, but not in the grammar per se). Therefore, there should
21017 be another means to enable it.
21018
21019 * src/getargs.c (getargs): Support `--locations'.
21020 (usage): Report it.
21021 * src/getargs.h (locationsflag): Export it.
21022 * src/lex.c (percent_table): Support `%locations'.
21023 * src/reader.c (yylsp_needed): Remove this variable, now replaced
21024 with `locationsflag'.
21025 * doc/bison.texinfo: Document `--locations' and `%locations'.
21026 Sort the options.
21027 * tests/calc.m4: Test it.
21028
21029 For regularity of the names, replace each
21030 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
21031 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
21032 In addition replace each `flag' with `_flag'.
21033
21034 2000-10-02 Akim Demaille <akim@epita.fr>
21035
21036 Also test parse error messages, including with YYERROR_VERBOSE.
21037
21038 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
21039 associative).
21040 Use it to check the computations.
21041 Use it to check `nonassoc' is honored.
21042 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
21043 `--yyerror-verbose'.
21044 (_AT_CHECK_CALC): Adjust to this option.
21045 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
21046
21047 2000-10-02 Akim Demaille <akim@epita.fr>
21048
21049 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21050 the latter demonstrates a flaw in the handling of non debugging
21051 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21052 was used in order to simplify:
21053
21054 #if YYDEBUG
21055 if (yydebug)
21056 {
21057 ...
21058 }
21059 #endif
21060
21061 into
21062
21063 if (yydebug)
21064 {
21065 ...
21066 }
21067
21068 unfortunately this leads to a CPP conflict when
21069 `--name-prefix=foo' is used since it produces `#define yydebug
21070 foodebug'.
21071
21072 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
21073 (YYDPRINTF): New macro.
21074 Spread its use.
21075 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
21076 the bison options.
21077 Also test `--verbose', `--defines' and `--name-prefix'.
21078
21079 2000-10-02 Akim Demaille <akim@epita.fr>
21080
21081 Improve the readability of the produced parsers.
21082
21083 * src/bison.s1: Formatting changes.
21084 Improve the comment related to the `$' mark.
21085 (yydefault): Don't fall through to `yyresume': `goto' there.
21086 * src/output.c (output_parser): When the `$' is met, skip the end
21087 of its line.
21088 New variable, `number_of_dollar_signs', to check there's exactly
21089 one `$' in the parser skeleton.
21090
21091 2000-10-02 Akim Demaille <akim@epita.fr>
21092
21093 * lib/xstrdup.c: New file, from the fileutils.
21094 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
21095 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
21096 instead of strlen + xmalloc + strcpy.
21097 * src/symtab.c (copys): Remove, use xstrdup instead.
21098
21099 2000-10-02 Akim Demaille <akim@epita.fr>
21100
21101 * src/gram.h (associativity): New enum type which replaces the
21102 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
21103 `right_assoc', `left_assoc' and `non_assoc'.
21104 Adjust all dependencies.
21105 * src/reader.c: Formatting changes.
21106 (LTYPESTR): Don't define it, use it as a literal in
21107 `reader_output_yylsp'.
21108 * src/symtab.h (symbol_class): New enum type which replaces the
21109 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
21110 `sunknown', `stoken and `snterm'.
21111
21112 2000-10-02 Akim Demaille <akim@epita.fr>
21113
21114 * src/getargs.c (fixed_outfiles): Rename as...
21115 (yaccflag): for consistency and accuracy.
21116 Adjust dependencies.
21117
21118 2000-10-02 Akim Demaille <akim@epita.fr>
21119
21120 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21121 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21122 difficult and introduced a lot of core dump. It turns out that
21123 Bison used an implementation of `xmalloc' based on `calloc', and
21124 at various places it does depend upon the initialization to 0. I
21125 have not tried to isolate the pertinent places, and all the former
21126 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21127 someone should address this issue.
21128
21129 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
21130 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

21137
21138 Various anti-`extern in *.c' changes.
21139
21140 * src/system.h: Include `assert.h'.
21141
21142 2000-10-02 Akim Demaille <akim@epita.fr>
21143
21144 * src/state.h (nstates, final_state, first_state, first_shift)
21145 (first_reduction): Move their exportation from here...
21146 * src/LR0.h: to here.
21147 Adjust dependencies.
21148 * src/getargs.c (statisticsflag): New variable.
21149 Add support for `--statistics'.

21161 * src/print.h: New file.
21162 Propagate its use.

21164 (verbose, terse): Replace with...
21165 (print_results): this new function.

21174 * src/conflicts.h: New file.
21175 Propagate its inclusion.
21176
21177 2000-10-02 Akim Demaille <akim@epita.fr>

21229
21230 `user_toknums' is output as a `short[]' in `output.c', while it is

21279 definitions in config.h.
21280
21281 2000-09-20 Akim Demaille <akim@epita.fr>
21282

21497 Change the handling of @s so that they behave exactly like $s.
21498 There is now a pseudo variable @$ (readble and writable), location
21499 of the lhs of the rule (by default ranging from the location of
21500 the first symbol of the rhs, to the location of the last symbol,

21536 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

22215 declaration to allow a multi-character symbol as an alias.
22216 (parse_thong_decl): New function.

22227 Revised and use multiple warnxxx functions to avoid using VARARGS1.
22228 (read_declarations): Improve the error message for
22229 an invalid character. Do not abort.
22230 (read_declarations, copy_guard, copy_action): Use
22231 printable_version to avoid unprintable characters in printed output.

22255 (safegetc): New function to deal with EOF gracefully.
22256 (literalchar); new function to deal with reading \ escapes.
22257 (lex): Use literalchar.
22258 (lex): Implemented "..." tokens.
22259 (literalchar, lex, parse_percent_token): Made tokenbuffer
22260 always contain the token. This includes growing the token
22261 buffer while reading an integer.
22262 (parse_percent_token): Replaced if-else statement with percent_table.
22263 (parse_percent_token): Added % declarations as another
22264 way to specify the flags -n, -l, and -r. Also added hooks for
22265 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22266 major changes to files.c.
22267 (lex) Retain in the incoming stream a character following
22268 an incorrect '/'.
22269 (skip_white_space, lex): Revised most error messages
