45 (Examples): Don't abbreviate node names.
46 (LocalWords): Remove abbreviations.
47 (Copying): Make description a sentence.
48 (Java Action Features): Remove period to match the rest of menu.

95 Support parametric types.
97 There are two issues to handle: first scanning nested angle
98 bracket pairs to support types such as std::pair< std::string,
99 std::list<std::string> > >.
101 Another issue is to address idiosyncracies of C++: do not glue two
102 closing angle brackets together (otherwise it's operator>>), and
103 avoid sticking blindly a TYPE to the opening <, as it can result
104 in '<:' which is a digraph for '['.
106 * src/scan-gram.l (brace_level): Rename as...
109 Implement support for complex tags.
112 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
113 (b4_symbol_variant): Leave space around types as parameters.

115 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
117 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
118 * tests/c++.at: Test parametric types.
120 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
123 This is not sufficient, but we test at least that the make_SYMBOL
124 interface is not affected by token.prefix. A more general test
125 will be implemented when the support of token.prefix is generalized
128 * tests/c++.at: One more variant test, using token.prefix.
130 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
132 Test the make_TOKEN interface.
133 * tests/c++.at (AT_CHECK_VARIANTS): Require and use locations.

155 Update variant.yy to newest interface.
156 * examples/variant.yy: Define lex_symbol.
159 2008-11-15 Akim Demaille <demaille@gostai.com>
161 Don't use locations in variant.yy.
162 * examples/variant.yy: Adjust to not using locations.

202 Move sc_tight_scope into maint.mk.
203 It does not work, and I don't know how it was supposed to work: it
204 seems to be looking for sources in the build tree. I just moved
205 it at a better place, fixing it is still required.
207 * src/local.mk (echo): Remove.
208 (sc_tight_scope): Move to...

221 Prefix all the paths with src/.
222 (AUTOMAKE_OPTIONS): Build object files in the sub dirs.
223 (AM_CPPFLAGS): Find find in builddir/src.
224 (YACC): Move the flags into...
226 * maint.mk (sc_tight_scope): Disable.
227 It used to bounce to the version in src/Makefile.am which is now
228 part of this very Makefile.
229 * Makefile.am, configure.ac: Adjust.
230 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
231 include "..." to find files "here": we are no longer in src/, so
232 qualify the includes with src/.
233 * doc/Makefile.am (PREPATH): No longer include the top_builddir
235 (.x.1): Adjust to be able to create src/foo from the top level
236 Makefile, instead of going bounce to src/Makefile the creation of

260 2008-11-15 Akim Demaille <demaille@gostai.com>
262 Remove examples/local.mk.
263 examples/calc++/Makefile.am might be interesting to keep as is, since
264 it is an example in itself.
266 * examples/Makefile.am: Rename as...
267 * examples/local.mk: this.
269 * Makefile.am, configure.ac: Adjust.
271 2008-11-15 Akim Demaille <demaille@gostai.com>
273 Remove build-aux/Makefile.am.
274 Recursive Makefiles are really way too slow, let's get rid of some of
277 * build-aux/Makefile.am: Rename as...
278 * build-aux/local.mk: this.
280 * Makefile.am, configure.ac: Adjust.
282 2008-11-15 Akim Demaille <demaille@gostai.com>
284 Provide convenience constructors for locations and positions.
285 * data/location.cc (position::position): Accept file, line and
286 column as arguments with default values.
287 Always qualify initial line and column literals as unsigned.
288 (location::location): Provide convenience constructors.
290 2008-11-15 Akim Demaille <demaille@gostai.com>
292 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
294 Using template buys us nothing, and makes it uselessly complex to
295 construct a symbol. Besides, it could not be generalized to other
296 languages, while make_FOO would work in C/Java etc.
298 * data/lalr1.cc (b4_symbol_): New.
300 (b4_symbol_constructor_declaration_)
301 (b4_symbol_constructor_definition_): Instead of generating
302 specializations of an overloaded template function, just generate
303 several functions whose names are forged from the token names
304 without the token.prefix.
305 (b4_symbol_constructor_declarations): Generate them for all the
306 symbols, not just by class of symbol type, now that instead of
307 specializing a function template by the token, we generate a
308 function named after the token.
309 (b4_symbol_constructor_specialization_)
310 (b4_symbol_constructor_specializations): Remove.
311 * etc/bench.pl.in: Adjust to this new API.
313 2008-11-13 Akim Demaille <demaille@gostai.com>
315 %define token.prefix.
316 Provide a means to add a prefix to the name of the tokens as
317 output in the generated files. Because of name clashes, it is
318 good to have such a prefix such as TOK_ that protects from names
319 such as EOF, FILE etc. But it clutters the grammar itself.
321 * data/bison.m4 (token.prefix): Empty by default.
322 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
323 * data/lalr1.cc (b4_symbol): Ditto.
325 2008-11-13 Akim Demaille <demaille@gostai.com>
327 Compute at M4 time some of the subtractions.
328 * data/lalr1.cc (b4_subtract): New.
329 (b4_rhs_data): Use it.
331 2008-11-13 Akim Demaille <demaille@gostai.com>
334 This allows the user to get the type of a token returned by yylex.
336 * data/lalr1.cc (symbol::token): New.
337 (yytoknum_): Define when %define lex_symbol, independently of
339 (yytoken_number_): Move into...
340 (symbol::token): here, since that's the only use.
341 The other one is YYPRINT which was not officially supported
342 by lalr1.cc, and anyway it did not work since YYPRINT uses this
343 array under a different name (yytoknum).
345 2008-11-13 Akim Demaille <demaille@gostai.com>
348 * TODO (YYERRCODE): Mention the case of $undef.
350 2008-11-13 Akim Demaille <demaille@gostai.com>
353 * TODO (YYPRINT): New.
355 2008-11-13 Akim Demaille <demaille@gostai.com>
358 * data/lalr1.cc, data/yacc.c: Fix the description of the
359 yytranslate and yytoknum tables.
361 2008-11-13 Akim Demaille <demaille@gostai.com>
363 Define make_symbol in the header.
364 To reach good performances these functions should be inlined (yet
365 this is to measure precisely). To this end they must be available
368 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
369 location_type with the class name.
370 Since will now be output in the header, declare "inline".
371 No longer use b4_symbol_constructor_specializations, but
372 b4_symbol_constructor_definitions in the header.
373 Don't call it in the *.cc file.
375 2008-11-13 Akim Demaille <demaille@gostai.com>
377 Define yytranslate in the header for lex_symbol.
378 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
379 into the header file when using %define lex_symbol.
380 (yytranslate_): Declare inline.
382 2008-11-13 Akim Demaille <demaille@gostai.com>
384 Define the constructors of symbol_type in
385 b4_symbol_constructor_definitions.
386 The constructors are called by the make_symbol functions, which a
387 forthcoming patch will move elsewhere. Hence the interest of
388 putting them together.
390 The stack_symbol_type does not need to be moved, it is used only
393 * data/lalr1.cc: Move symbol_type and symbol_base_type
395 (b4_symbol_constructor_definitions): here.
398 2008-11-13 Akim Demaille <demaille@gostai.com>
400 Make it easier to move the definition of yytranslate_.
401 Forthcoming changes will make it possible to use yytranslate_
402 from outside the parser implementation file.
404 * data/lalr1.cc (b4_yytranslate_definition): New.
407 2008-11-13 Akim Demaille <demaille@gostai.com>
409 Remove useless class specification.
410 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
411 to refer to the class name to use a type defined by the class for
412 arguments of member functions.
414 2008-11-13 Akim Demaille <demaille@gostai.com>
416 Finer input type for yytranslate.
417 This patch is debatable: the tradition expects yylex to return an int
418 which happens to correspond to token_number (which is an enum). This
419 allows for instance to return characters (such as '*' etc.). But this
420 goes against the stronger typing I am trying to have with the new
421 lex interface which return a symbol_type. So in this case, feed
422 yytranslate_ with a token_type.
424 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
427 2008-11-13 Akim Demaille <demaille@gostai.com>
429 Honor lex-params in %define lex_symbol mode.
430 * data/lalr1.cc: Use b4_lex_param.
432 2008-11-13 Akim Demaille <demaille@gostai.com>
435 * src/output.c (symbol_definitions_output): Rename symbol
436 attributes type_name and has_type_name as type and has_type.
437 * data/lalr1.cc: Adjust uses.
439 2008-11-13 Akim Demaille <demaille@gostai.com>
441 Use b4_type_names for the union type.
442 The union used to compute the size of the variant used to iterate
443 over the type of all the symbols, with a lot of redundancy. Now
444 iterate over the lists of symbols having the same type-name.
446 * data/lalr1.cc (b4_char_sizeof_): New.
447 (b4_char_sizeof): Use it.
448 Adjust to be called with a list of numbers instead of a single
450 Adjust its caller for new-line issues.
452 2008-11-13 Akim Demaille <demaille@gostai.com>
454 Define the "identifier" of a symbol.
455 Symbols may have several string representations, for instance if
456 they have an alias. What I call its "id" is a string that can be
457 used as an identifier. May not exist.
459 Currently the symbols which have the "tag_is_id" flag set are
460 those that don't have an alias. Look harder for the id.
462 * src/output.c (is_identifier): Move to...
463 * src/symtab.c (is_identifier): here.
464 * src/symtab.h, src/symtab.c (symbol_id_get): New.
465 * src/output.c (symbol_definitions_output): Use it to define "id"
467 Remove the definition of "tag_is_id".
468 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
469 "tag_is_id" were used to produce code.
470 We still use "tag" for documentation.
472 2008-11-11 Akim Demaille <demaille@gostai.com>
474 Locations are no longer required by lalr1.cc.
475 * data/lalr1.cc (_b4_args, b4_args): New.
476 Adjust all uses of locations to make them optional.
477 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
478 (AT_CHECK_NAMESPACE): Check the use of locations.
479 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
480 without locations with lalr1.cc.
482 * tests/output.at: Check lalr1.cc with and without location
484 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
487 2008-11-11 Akim Demaille <demaille@gostai.com>
490 * tests/local.at (AT_FULL_COMPILE): New.
491 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
493 2008-11-11 Akim Demaille <demaille@gostai.com>
495 Support parens in calc++.
496 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
497 * examples/calc++/test (run): Check the expected output.
501 2008-11-11 Akim Demaille <demaille@gostai.com>
503 Simplify lalr1.cc since %defines is mandatory.
504 * data/lalr1.cc: Remove useless calls to b4_defines_if.
506 2008-11-11 Akim Demaille <demaille@gostai.com>
509 * TODO (yysyntax_error): New item.
511 2008-11-11 Akim Demaille <demaille@gostai.com>
514 * data/lalr1.cc: Use b4_error_verbose_if instead of #if
517 2008-11-11 Akim Demaille <demaille@gostai.com>
519 Support i18n of the parse error messages.
520 * TODO (lalr1.cc/I18n): Remove.
521 * data/lalr1.cc (yysyntax_error_): Support the translation of the
522 error messages, as done in yacc.c.
523 Stay within the yy* pseudo namespace.
525 2008-11-11 Akim Demaille <demaille@gostai.com>
528 * TODO (single stack, yysyntax_error): New.
530 2008-11-11 Akim Demaille <demaille@gostai.com>
532 Make it possible to return a symbol_type from yylex.
533 * data/lalr1.cc (b4_lex_symbol_if): New.
534 (parse): When lex_symbol is defined, expected yylex to return the
536 * etc/bench.pl.in (generate_grammar_list): Extend to support this
538 (bench_variant_parser): Exercise it.
540 2008-11-11 Akim Demaille <demaille@gostai.com>
542 Remove useless bench case.

546 2008-11-11 Akim Demaille <demaille@gostai.com>
548 Improve display of directives.
549 * etc/bench.pl.in (parse_term): Don't add useless eol.
551 2008-11-11 Akim Demaille <demaille@gostai.com>
553 Use string_cast in the bench.
554 * etc/bench.pl.in (generate_grammar_list): Define and use
557 2008-11-11 Akim Demaille <demaille@gostai.com>
559 Replace yychar with a Boolean.
560 * data/lalr1.cc (parse::yychar): Replace by...
561 (parse::yyempty): this.

568 2008-11-11 Akim Demaille <demaille@gostai.com>
570 Let yytranslate handle the eof case.
571 * data/lalr1.cc (yytranslate_): Handle the EOF case.
573 No longer expect yychar to be equal to yyeof_, rather, test the
574 lookahead's (translated) kind.
576 2008-11-11 Akim Demaille <demaille@gostai.com>
578 yychar cannot be empty in yyerrlab.
579 * TODO (yychar == yyempty_): New.
580 * data/lalr1.cc: Remove the handling of this case.
581 This eases forthcoming changes related to yychar and yytranslate.
583 2008-11-11 Akim Demaille <demaille@gostai.com>
585 Bench: syntactic sugar for %define/#define.
586 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
587 (&bench_push_parser, bench_variant_parser): Use this feature.
591 2008-11-11 Akim Demaille <demaille@gostai.com>
593 Less memory pressure on the "list" bench.
594 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
595 the values, to limit memory pressure.
597 2008-11-11 Akim Demaille <demaille@gostai.com>
599 Introduce make_symbol.
600 make_symbol provides a means to construct a full symbol (kind,
601 value, location) in a single shot. It is meant to be a Symbol
602 constructor, parameterized by the symbol kind so that overloading
603 would prevent incorrect kind/value pairs. Unfortunately
604 parameterized constructors do not work well in C++ (unless the
605 parameter also appears as an argument, which is not acceptable),
606 hence the use of a function instead of a constructor.
608 * data/lalr1.cc (b4_symbol_constructor_declaration_)

628 (symbol_definitions_output): Use it to define tag_is_id.
629 But maybe this should be done at m4 level?
631 2008-11-11 Akim Demaille <demaille@gostai.com>
633 Test 214 was failing: it greps with a pattern containing [ ]*
634 which obviously meant to catch spaces and tabs, but contained only
635 spaces. Tabulations in sources are a nuisance, so to simplify the
636 matter, get rid of all the tabulations in the Java sources. The
637 other skeletons will be treated equally later.
639 * data/java.m4, data/lalr1.java: Untabify.

819 2008-11-10 Akim Demaille <demaille@gostai.com>
821 Change the handling of the symbols in the skeletons.
822 Before we were using tables which lines were the symbols and which
823 columns were things like number, tag, type-name etc. It is was
824 difficult to extend: each time a column was added, all the numbers had
825 to be updated (you asked for colon $2, not for "tag"). Also, it was
826 hard to filter these tables when only a subset of the symbols (say the
827 tokens, or the nterms, or the tokens that have and external number
828 *and* a type-name) was of interest.
830 Now instead of monolithic tables, we define one macro per cell. For
831 instance "b4_symbol(0, tag)" is a macro name which contents is
832 self-decriptive. The macro "b4_symbol" provides easier access to
835 * src/output.c (type_names_output): Remove.

879 2008-11-10 Akim Demaille <demaille@gostai.com>
881 Add %precedence support.
882 Unfortunately it is not possible to reuse the %prec directive. This
883 is because to please POSIX, we do not require to end the rules with a
884 semicolon. As a result,
888 is ambiguous: either a rule which precedence is that of baz, or a rule,
889 and then a declaration of the precedence of the token baz.
891 * doc/bison.texinfo: Document %precedence.
892 (Precedence Only): New.

1019 Rely on the state stack to display reduction traces.
1020 To display rhs symbols before a reduction, we used information
1021 about the rule reduced, which required the tables yyrhs and
1022 yyprhs. Now use rely only on the state stack to get the same

1151 Add "%define assert" to variants.
1152 This is used to help the user catch cases where some value gets
1153 ovewritten by a new one. This should not happen, as this will
1156 Unfortunately this uncovered a bug in the C++ parser itself: the
1157 lookahead value was not destroyed between two calls to yylex. For
1158 instance if the previous lookahead was a std::string, and then an int,
1159 then the value of the std::string was correctly taken (i.e., the
1160 lookahead was now an empty string), but std::string structure itself
1163 This is now done in variant::build(other&) (which is used to take the
1164 value of the lookahead): other is not only stolen from its value, it
1165 is also destroyed. This incurs a new performance penalty of a few
1166 percent, and union becomes faster again.
1168 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

1447 Fuse the three stacks into a single one.
1449 In order to make it easy to perform benchmarks to ensure that
1450 there are no performance loss, lalr1.cc is forked into
1451 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
1454 Meanwhile, to make sure that lalr1-fusion.cc is correctly
1455 exercized by the test suite, the user must install a symbolic link
1456 from lalr1.cc to it.
1458 Instead of having three stacks (state, value, location), use a
1459 stack of triples. This considerably simplifies the code (and it
1460 will be easier not to require locations as currently does the C++
1461 parser), and also gives a 10% speedup according to
1462 etc/bench (probably mainly since memory allocation is done once
1463 instead of three times).
1465 Another motivation is to make it easier to destruct properly
1466 semantic values: now that they are bound to their state (hence
1467 symbol type) it will be easier to call the appropriate destructor.
1469 These changes should probably benefit the C parser too.
1471 * data/lalr1.cc: Copy as...
1472 * data/lalr1-fusion.cc: this new file.
1473 (b4_rhs_value, b4_rhs_location): New definitions overriding those
1475 (state_stack_type, semantic_stack_type, location_stack_type)
1476 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
1477 (data_type, stack_type, yystack_): New.
1478 (YYLLOC_DEFAULT, yypush_): Adjust.
1479 (yyerror_range): Now based on data_type, not location_type.
1481 2008-11-03 Akim Demaille <demaille@gostai.com>
1483 Push the state, value, and location at the same time.
1484 This is needed to prepare a forthcoming patch that fuses the three
1487 * data/lalr1.cc (parser::yypush_): New.
1488 (parser::yynewstate): Change the semantics: instead of arriving to
1489 this label when value and location have been pushed, but yystate
1490 is to be pushed on the state stack, now the three of them must
1491 have been pushed before. yystate still must be the new state.
1492 This allows to use yypush_ everywhere instead of individual
1493 handling of the stacks.
1495 2008-11-03 Akim Demaille <demaille@gostai.com>
1497 Prefer references to pointers.
1498 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
1499 definition to use references instead of pointers.
1500 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
1501 Take the value and location as references.
1504 2008-11-03 Akim Demaille <demaille@gostai.com>
1506 stack::size instead of stack::height.
1507 * data/lalr1.cc (stack::height): Rename as...
1508 (stack::size): this.
1509 Fix the output type.
1512 2008-11-03 Akim Demaille <demaille@gostai.com>
1514 Use variants to support objects as semantic values.
1515 This patch was inspired by work by Michiel De Wilde. But he used
1516 Boost variants which (i) requires Boost on the user side, (ii) is
1517 slow, and (iii) has useless overhead (the parser knows the type of
1518 the semantic value there is no reason to duplicate this
1519 information as Boost.Variants do).
1521 This implementation reserves a buffer large enough to store the
1522 largest objects. yy::variant implements this buffer. It was
1523 implemented with Quentin Hocquet.
1525 * src/output.c (type_names_output): New.
1526 (output_skeleton): Invoke it.
1527 * data/c++.m4 (b4_variant_if): New.

1530 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
1531 (b4_char_sizeof, yy::variant): New.
1532 (parser::parse): If variants are requested, define
1533 parser::union_type, parser::variant, change the definition of
1534 semantic_type, construct $$ before running the user action instead
1535 of performing a default $$ = $1.
1536 * examples/variant.yy: New.
1537 Based on an example by Michiel De Wilde.
1539 2008-11-03 Akim Demaille <demaille@gostai.com>
1541 Parameterize the extraction of semantic values.
1542 To make future changes easier, no longer rely on ".TYPE" being the
1543 way to get a semantic value.

1547 * data/c++.m4, data/yacc.c: Use it.
1548 * data/glr.c: Use b4_symbol_value.

1843 (m4_prepend): Remove, as it is unused and inherently quadratic,
1844 whereas m4_append is linear in newer m4.

1925 * NEWS (2.3b+): Rename to...
1926 (?.?): ... this because we're dropping the "+" version naming scheme,
1927 but, in general, we still can't be sure of our next release name.
1928 * bootstrap: Add a quick hack to remove from .gitignore the
1929 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
1930 entry. This should really be fixed in gnulib instead.
1931 * bootstrap.conf (gnulib_modules): Add gnumakefile.
1932 * configure.ac (AC_INIT): Set version name by invoking
1933 build-aux/git-version-gen.

1963 Fix some .gitignore and .cvsignore problems.
1964 * bootstrap (insert_sorted_if_absent): Replace all uses with...

1966 .gitignore entries before passing them to insert_sorted_if_absent.
1967 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
1968 .cvsignore files are maintained even though Bison developers run
1969 bootstrap while using Git.
1970 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
1973 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
1974 unneeded. Reported by Eric Blake.

1989 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
1990 the first argument because it may become position-dependent, and unset
1991 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
1992 Add comments explaining these issues in more detail.
1994 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>
1996 Add .gitignore everywhere based on .cvsignore.

2027 2008-05-23 Joel E. Denny <jdenny@ces.clemson.edu>
2029 * HACKING: Don't say don't mention HACKING in the ChangeLog. We've
2030 been doing it for years.
2031 (Test suite): Mention maintainer-push-check and maintainer-xml-check.
2032 (Release Procedure): Add FIXME about make alpha being unmaintained.

2052 * THANKS: Add Eric Blake.
2054 2008-04-23 Eric Blake <ebb9@byu.net>
2056 Revert prior patch, by working around autoconf regression.
2057 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
2058 ("Output file name: ("): Uncomment test.
2059 ("Output file name: )"): Likewise.
2060 Based on an idea from Noah Misch.
2062 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

2076 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2078 Update to the current gnulib CVS repository, and fix trigraph handling
2080 * bootstrap: Update gnulib CVS repository URL.
2081 (symlink_to_dir): Encapsulate the code that guarantees the destination
2082 directory exists into...
2083 (check_dst_dir): ... this new function, and...
2084 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
2085 fail when copying files into lib/uniwidth/.
2086 * src/output.c (prepare_symbols): When writing yytname muscles, where
2087 symbol names will be encoded in C-string literals, tell quotearg to
2088 escape trigraphs. This used to be the default in gnulib.
2089 * tests/regression.at (Token definitions): Because of the change in
2090 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2091 escapes trigraphs in symbol names. Thus, yytname no longer has
2092 trigraphs unnecessarily doubly escaped. Update test case output.
2093 Extend test case to be sure Bison's own error messages will no longer
2094 have trigraphs in symbol names unnecessarily escaped once.
2096 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>

2108 * NEWS (2.3a+): Mention that -g now takes an argument.
2109 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
2110 consistency. Update the -g and -x entries now that they take
2111 arguments. Use brackets to indicate optional arguments.
2112 * src/getargs.c (usage): Explain the relationship between arguments of
2113 long and short options more completely. Document --defines and -d
2114 separately since the former takes an argument but, for POSIX Yacc, the
2116 (short_options): Let -W take an optional argument like --warnings.

2131 -g and -x take optional arguments, just like their long options.

2134 Fix the handling of $opt which resulted in all the argument to be
2135 considered as optional.
2137 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

2143 (Bison Options): In the -L and --language entry, mention Java.

2172 <http://lists.gnu.org/archive/html/help-bison/2008-02/msg00023.html>.
2173 * data/yacc.c: Clean up whitespace in the output a little.
2174 (yypstate_allocated): Define for impure push parsers regardless of
2175 whether the pull interface is also requested.
2176 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
2177 check impure push parsers without the pull interface.
2179 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since
2180 yyerror takes arguments specified by %parse-param while yypstate_new

2773 (C++ Bison Interface): Mention `%define namespace' instead of
2775 (Table of Symbols): Remove the `%define push_pull' entry. The %define

2871 parsing requests here...
2872 * data/yacc.c: ... hack this to switch to push.c any time

2874 will go away when we mv push.c yacc.c.
2875 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
2876 push parsing is not supported since unused %define variables are

3085 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3087 Get rid of broken %no-parser, -n, and --no-parser implementation and
3089 * TODO: Don't mention them.
3090 * doc/bison.1: Likewise.
3091 * doc/bison.texinfo (Decl Summary): Likewise.
3092 (Bison Options): Likewise.
3093 (Option Cross Key): Likewise.
3094 * src/getargs.c (no_parser_flag): Remove global variable.
3095 (usage): Don't print description of -n and --no-parser.
3096 (long_options): Remove --no-parser entry here.
3097 (getargs): Remove -n case in the switch here.
3098 * src/getargs.h (no_parser_flag): Remove extern.
3099 * tests/regression.at (Web2c Actions): Remove comment that mentions
3102 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3104 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
3105 name user variables starting with `yy'. Just pass NULL instead of a
3106 dummy local &yylval to yypush_parse.
3107 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
3110 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
3112 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
3113 true since it's then always used regardless of whether yyoverflow is
3114 defined. Reported by Christian Burger at
3115 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
3116 * THANKS: Add Christian Burger.
3118 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3119 node names: say "Decl Summary" not "Bison Declaration Summary".
3121 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
3123 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
3124 determine whether this function has already complained about an invalid
3125 value for a %define boolean variable, don't check whether Bison has
3126 ever examined the value. As written, the check was a tautology.
3127 Instead, record and check for this complaint using a separate muscle.
3129 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
3131 Fix push parsing memory leak reported by Brandon Lucia at
3132 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
3133 * THANKS: Add Brandon Lucia.
3134 * data/push.c (yypstate_delete): Free the stack if it was reallocated
3135 but the parse never completed and thus freed it.
3136 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
3137 * tests/testsuite.at: Include push.at.
3138 * test/push.at: New.
3139 (Push Parsing: Memory Leak for Early Deletion): New test case.
3141 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3143 Improve handling of multiple S/R conflicts in the same state and of S/R
3144 conflicts involving multiple reductions.
3145 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3146 set for a state here or Bison will abort if it is reassigned on a
3147 later conflicted reduction in the same state.
3148 Similarly, don't finalize and assign the solved conflicts report here
3149 or it will be lost if it is reassigned on a later conflicted reduction
3151 (set_conflicts): Instead, assign them both here after all S/R conflicts
3152 in the state have been fully examined.
3153 * src/print.c (shift_set): Rename to...
3154 (no_reduce_set): ... this.
3155 (print_reductions): Update for rename, and add %nonassoc error action
3156 tokens to no_reduce_set so that, when printing the first remaining
3157 reduction on an error action token, the reduction is enclosed in
3159 (print_results): Update for rename.
3160 * tests/conflicts.at (Solved conflicts report for multiple reductions
3161 in a state): New test case.
3162 (%nonassoc error actions for multiple reductions in a state): New test
3165 * src/main.c (main): Don't depend on C99 features.
3167 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
3169 * build-aux/.cvsignore: Add compile.
3170 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
3173 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
3175 * bootstrap (slurp): Create target directories that don't exist.
3176 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
3178 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3180 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
3182 * closure.c (closure): Likewise.
3183 * state.h (reductions): Comment sorting of rules.
3184 (state): Comment sorting of items.
3186 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
3188 Fix C++ test cases after recent Gnulib changes. Discussed starting at
3189 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
3190 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
3191 definition in order to avoid Gnulib headers since we don't use config.h
3193 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
3194 rather than AT_DATA so that config.h is included.
3196 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
3198 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
3199 instead of fprintf. Guard these functions with #if YYDEBUG instead of
3200 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
3201 and so that YYFPRINTF is guaranteed to be defined here.
3203 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
3205 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
3207 (muscle_percent_define_check_values): ... this more helpful function.
3208 Again, it's not used yet, but it will be.
3209 * src/muscle_tab.h: Likewise.
3211 Improve some comments in parser table construction.
3212 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
3213 (generate_states): Don't mention ruleset, which is internal to closure.
3214 * src/closure.c (closure): Explain sorting of core and itemset, which
3215 is required for this function to behave correctly.
3216 * src/closure.h (closure): Mention sorting.
3218 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
3220 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3221 move the check for disabled transitions to an aver since conflict
3222 resolution hasn't happened yet.
3224 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3225 labels a state as inconsistent just because it has error transitions.
3226 The original form of this check appeared in revision 1.1 of lalr.c,
3227 which was committed on 1991-12-21. Now (at least), changing the
3228 consistency label on such a state appears to have no useful effect in
3229 any of the places it is examined, which I enumerate below. The key
3230 point to understanding each item in this enumeration is that a state
3231 with an error transition is labelled consistent in the first place only
3232 if it has no rules, so the check cannot matter for states that have
3233 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3234 to try to identify its conflicts, and a state must have *rules* to have
3235 conflicts. (2) Labelling a state as inconsistent will affect how
3236 action_row sets the default *rule* for the state. (3) Labelling a
3237 state as inconsistent will cause build_relations to add lookback edges
3238 to *rules* in that state.
3239 * src/state.h (struct state): Word the comment for member consistent
3242 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
3244 Don't depend on C99 features.
3245 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
3246 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
3247 * src/reader.c (check_and_convert_grammar): Fix for-loop.
3248 * src/state.c (state_mark_reachable_states): Fix for-loop.
3249 (state_remove_unreachable_states): Fix for-loop.
3251 Don't widen struct state with member reachable just to temporarily
3252 record reachability. Instead, use a local bitset.
3253 * src/state.h (struct state): Remove member.
3254 * src/state.c (state_new): Don't initialize it.
3255 (state_mark_reachable_states): Rename to...
3256 (state_record_reachable_states): ... this, and use bitset.
3257 (state_remove_unreachable_states): Use bitset.
3259 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
3261 * src/Makefile.am (yacc): Quote target action commands properly so
3262 that the yacc script isn't corrupt. Reported by Hans Aberg at
3263 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
3265 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
3266 the case of pure parsers. Reported by Frans Englich at
3267 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3268 * THANKS: Add Frans Englich.
3270 * NEWS (2.3a+): In the %code entry, reference section `Bison
3271 Declaration Summary' from the manual now since the %code summary has
3273 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3274 in the rules section must be terminated by semicolons.
3276 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3278 Extend the front-end API for %define variables to more completely
3279 mirror the back-end. This will be useful in the future.
3280 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3281 Update comments to mention the new front-end counterparts of these
3283 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

3293 * src/muscle_tab.h (muscle_percent_define_get,
3294 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
3297 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
3299 * NEWS (2.3a+): Mention yesterday's state-removal change.
3300 (2.3a): Remove the %language entry, which was added after 2.3a.
3301 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
3302 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
3303 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
3304 tests/existing.at: Update copyright date.
3306 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3308 If conflict resolution makes states unreachable, remove those states,
3309 report rules that are then unused, and don't report conflicts in those

3326 an unused rule is discovered.
3328 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3330 Minor code cleanup in parser table construction.
3331 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
3332 (new_itemsets, save_reductions): Update for rename to nitemset.
3333 * src/closure.c (nritemset): Rename to...
3334 (nitemset): ... this since the "r" appears to meaningless and isn't
3335 used in the comments.
3336 (closure): Update for rename.
3337 * src/closure.h (nritemset): Update extern to...
3338 (nitemset): ... this.

3435 muscle_percent_define_default): New functions mimicking
3436 b4_percent_define_flag_if and b4_percent_define_default.
3438 For %define variables, report locations for invalid values and

3463 * src/print.c (lookahead_set, state_default_rule): Remove.
3464 (print_reductions): Replace state_default_rule invocation with
3465 equivalent use of yydefact, which was computed in token_actions in
3467 (print_results): Don't allocate lookahead_set.
3469 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
3471 * data/lalr1.java: Prefix all private members with yy.
3473 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
3475 Use YYFPRINTF instead of fprintf where appropriate. Reported by
3476 Sebastien Fricker at
3477 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
3478 * THANKS: Add Sebastien Fricker.

3493 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
3495 Undo my 2007-02-07 change, switching back to the c-strcase module
3496 introduced in the 2007-02-03 change. Bruno Haible reported that
3497 the 2007-02-07 change would be dangerous in Turkish if we add a
3498 language whose name contains "i", since "i" is not lowercase "I"
3500 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
3501 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,

3508 2007-02-11 Bruno Haible <bruno@clisp.org>
3510 Enable the Java related testsuite tests when the only Java compiler
3511 found is a gcj < 4.3. Discussed at
3512 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
3513 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
3515 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
3517 * data/Makefile.am: Update copyright date.
3518 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
3519 yypstate_new returns NULL.
3520 (yypstate_new): Return NULL if malloc does.
3521 * src/reader.c (packgram): Move translation of rule actions from the
3522 beginning of packgram to...
3523 (check_and_convert_grammar): ... here right before packgram is invoked
3524 so it's easier to write more complete comments, and remove redundant
3527 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
3529 As in semantic actions, make @$ in %initial-action, %destructor, and
3530 %printer imply %locations.
3531 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
3533 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
3534 (@$ in %initial-action implies %locations,
3535 @$ in %destructor implies %locations,
3536 @$ in %printer implies %locations): ... these new test cases.
3538 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3540 Undo most of the 2007-02-03 change, switching to the strcase module
3541 now that gnulib strcase has been fixed.
3542 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
3543 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
3544 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
3545 * m4/.cvsignore: Add strcase.m4.
3546 * src/getargs.c: Revert 2007-02-03 change, as follows.
3547 Don't include c-strcase.h.
3548 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
3549 strcasecmp has "unspecified behavior" outside the POSIX locale,
3550 but it works fine in practice if at least one argument is ASCII,
3551 as is the case in Bison.
3553 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
3555 * tests/java.at: Skip tests if only one of javac/java is present.
3556 Reported by Joel E. Denny.
3557 * tests/atlocal.in: Adjust copyright years.
3559 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
3561 * data/lalr1.java (Stack): Work around old verifiers that disallow
3562 access to the private fields of an inner class, from the outer class.
3563 We can make Stack's fields public because user code doesn't have access
3564 to the instance of Stack used by parse(). Reported by Paul Eggert.
3566 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3568 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
3569 the right spot for these files?
3570 * bootstrap.conf (gnulib_modules): Add c-strcase.
3571 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
3573 * src/getargs.c: Include c-strcase.h.
3574 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
3575 to avoid unspecified behavior.
3577 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
3579 * doc/bison.texinfo (Decl Summary): Correct typo.
3581 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
3583 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
3584 Complain if the value does not match empty, "true" or "false".
3585 * data/c++.m4: Adjust default definitions of %define variables.
3586 * data/java.m4: Adjust default definitions of %define variables.
3587 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
3589 * tests/input.at (Boolean %define variables): Test new behavior.
3591 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
3593 * NEWS: Mention java.
3594 * TODO: Remove things that are done.
3595 * bootstrap.conf: Add javacomp-script and javaexec-script.
3596 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
3598 * data/Makefile.am: Add new files.
3599 * data/java-skel.m4: New.
3600 * data/java.m4: New.
3601 * data/lalr1.java: New.
3603 * doc/bison.texinfo: Put "A Complete C++ Example" under
3604 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
3605 under Other Languages.
3607 * src/getargs.c (valid_languages): Add Java.
3608 * src/getargs.h (struct bison_language): Update size of string fields.
3610 * tests/Makefile.am: Add java.at.
3611 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
3612 * tests/java.at: New.
3613 * tests/testsuite.at: Include it.
3615 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
3618 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
3619 at_directive_argv arguments so these no longer have to be global
3620 variables. Also, update the implementation for the following changes.
3621 (fail_for_at_directive_too_many_args,
3622 fail_for_at_directive_too_few_args): Add at_directive_name argument.
3623 (at_directive_name): Remove as at_directive_argv[0] will be used for
3625 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
3626 for the directive name.
3627 (at_directive_argc, at_directive_argv): Make these local within
3628 skel_lex instead of global.
3629 (INITIAL): Update directive start action for above changes.
3630 (SC_AT_DIRECTIVE_ARG): Rename to...
3631 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
3632 (SC_AT_DIRECTIVE_SKIP_WS): Update.
3633 (scan_skel): Move yylex_destroy to...
3634 (skel_scanner_free): ... here.
3635 * tests/skeletons.at (installed skeleton file name): Rename to...
3636 (installed skeleton file names): ... this.
3638 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
3640 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3641 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
3642 Summary" not "Directives".
3643 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
3644 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
3645 since the former is now the more complete one.
3646 (Prologue Alternatives): Likewise and do the same for %defines.
3647 (Table of Symbols): Add summary of %code, add summary of %define, and
3648 move full %code documentation to...
3649 (Decl Summary): ... here for consistency with other entries in these
3651 Move %define entry in order to keep this list alphabetized.
3652 Reword %define entry a little to put less emphasis on the skeleton
3653 concept, which most users shouldn't have to think about.
3655 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
3657 Adjust to recent gnulib changes.
3658 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
3659 Add string.h, string_.h, unistd_.h, wchar_.h.
3660 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
3661 * src/system.h: Don't include <stpcpy.h>; this is now done by
3664 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
3666 Simplify implementation of unqualified %code, implement macros for
3667 uniform treatment of boolean %define flags. Document %define.
3668 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
3669 b4_percent_code_ifdef): New.
3670 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
3671 * data/c++.m4: Define default value for global_tokens_and_yystype.
3672 * data/glr.cc: Likewise.
3673 * data/location.cc: Use b4_percent_define_flag_if.
3675 * doc/bison.texinfo (Decl Summary): Document %define.
3677 * src/parse-gram.y (Unqualified %code): Change muscle name to
3679 (content.opt): Default to empty.
3681 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
3683 Implement support for relative and absolute skeleton file names.
3684 Discussed starting at
3685 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
3686 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
3687 (Bison Options): Document in --skeleton entry.
3688 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
3689 full_skeleton can't necessarily hold all of pkgdatadir.
3690 If the specified skeleton file name contains a `/', don't prepend
3692 * src/parse-gram.y (prologue_declaration): If the specified skeleton
3693 file name contains a `/', prepend the grammar file directory.
3694 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
3695 * skeletons.at: New file.
3696 (relative skeleton file names): New test case.
3697 (installed skeleton file names): New test case.
3698 * tests/testsuite.at: Include skeletons.at.
3700 * bootstrap: Update copyright to 2007.
3702 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
3704 * bootstrap: Remove occurrences of .#bootmp from the files.
3706 2007-01-17 Akim Demaille <akim@epita.fr>
3708 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
3710 Use per-type %printer.
3712 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
3714 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

3722 2007-01-16 Akim Demaille <akim@epita.fr>
3724 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
3726 (Calc++ Scanner): Exit with failure if we can't open the input
3728 Accept "-" standing for stdin.
3729 (Calc++ Top Level): Print the result only if the parsing was
3732 2007-01-16 Akim Demaille <akim@epita.fr>
3734 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
3736 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
3737 and Joel E. Denny <jdenny@ces.clemson.edu>
3739 Clean up %define and %code implementation in M4 some. Most
3740 importantly, rename all related macros to be in the b4_percent_define
3741 and b4_percent_code namespaces. Also, complete support for `.' in
3742 %define variable names and %code qualifiers.
3743 * data/bison.m4 (b4_check_user_names): Check for special
3744 "SKELETON-NAMESPACE(name)" macros instead of using two nested
3746 (b4_get_percent_define, b4_get_percent_code): Rename to...
3747 (b4_percent_define_get, b4_percent_code_get): ... these.
3748 Extend documentation with examples.
3749 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
3750 b4_percent_define_skeleton_variables and
3751 b4_percent_code_skeleton_qualifiers.
3752 Expect any value for the %define variable `foo' to be stored in the
3753 macro named `b4_percent_define(foo)'; expect any %code blocks for the
3754 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
3755 expect any unqualified %code blocks to be stored in a macro named
3756 `b4_percent_code_unqualified'.
3757 Use m4_indir so that %define variable names and %code qualifiers can
3758 contain `.', which is allowed by the grammar parser.
3759 (b4_percent_define_default): New macro to set a default value for a
3761 (m4_wrap): Update wrapped code, and fix some underquoting.
3762 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
3763 Expect grammar uses of %define variables and %code qualifiers to be
3764 defined in b4_percent_define_user_variables and
3765 b4_percent_code_user_qualifiers.
3766 * data/c++.m4: Use b4_percent_define_default rather than
3767 m4_define_default. Fix some underquoting. Skeleton usage of %define
3768 variable define_location_comparison now implies skeleton usage of
3769 %define variable filename_type.
3770 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3771 data/push.c, data/yacc.c: Update macro names.
3772 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
3775 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3777 DJGPP specific issues.
3779 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
3780 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
3782 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3784 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
3785 run parsers in all tests so that Valgrind is invoked during
3786 maintainer-check-valgrind.
3787 (Duplicate representation of merged trees): Free all semantic values.
3788 (Duplicated user destructor for lookahead): Likewise.
3790 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3792 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
3793 command-line prefix.
3794 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
3795 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
3796 miss Valgrind messages.
3797 (Exploding the Stack Size with Malloc): Likewise.
3799 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3801 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
3802 locals. Reported by Juan Manuel Guerrero at
3803 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
3804 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
3805 Fix some indentation also.
3806 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
3807 explaining this issue.
3809 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
3810 and Joel E. Denny <jdenny@ces.clemson.edu>
3812 Simplify union and prologue handling, and escape union and lex/parse
3813 params with digraphs.
3814 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
3815 values to the empty string since these are no longer guaranteed
3816 initialized by the front-end.
3817 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
3818 braces around b4_user_stype since this is no longer done by the
3820 * src/files.c, src/files.h (pre_prologue_obstack,
3821 post_prologue_obstack): Remove.
3822 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
3823 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
3824 with digraphs. This fixes lex params and parse params.
3825 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
3826 * src/output.c (prepare): Remove muscle insertion of the prologues.
3827 (output): Remove freeing of pre_prologue_obstack and
3828 post_prologue_obstack.
3829 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
3830 than prologue_augment for prologue parsing so you don't need prologue
3832 (grammar_declaration): For %union RHS, use `braceless' instead of
3833 "{...}" so that braces are already stripped and code is escaped with
3835 * src/reader.c (prologue_augment): Remove.
3836 (reader): Remove initialization of pre_prologue_obstack and
3837 post_prologue_obstack.
3838 * src/reader.h (prologue_augment): Remove.
3840 * data/c.m4: Remove stray parenthesis.
3842 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3844 Remove quotes from variables names in %define directives and from
3845 qualifiers in %code directives, and restrict the characters that are
3846 allowed in them to M4-friendly ones. For %define, continue to support
3847 the quoted form as a deprecated feature. Discussed starting at
3848 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
3849 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
3851 * doc/bison.texinfo (Prologue Alternatives): Update.
3852 (Decl Summary): In %defines entry, update mention of `%code requires'
3853 and `%code provides'.
3854 (C++ Location Values): Update %define uses.
3855 (Calc++ Parser Interface): Likewise.
3856 (Calc++ Parser): Likewise, and update `%code requires' uses.
3857 (Table of Symbols): Update %code documentation.
3858 * src/parse-gram.y (prologue_declaration): For %define variables, use
3859 `variable' instead of `STRING'.
3860 (grammar_declaration): For %code qualifiers, use `ID' instead of
3862 (variable): New nonterminal that takes an `ID' or a `STRING'.
3863 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
3865 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
3866 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
3867 (%define errors): Update %define uses.
3869 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3871 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
3872 instead of muscle_insert for %define values so that M4-special
3873 characters are replaced with digraphs.
3874 * tests/input.at (%define errors): Extend to check weird values.
3876 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3878 Instead of having skeletons declare all valid %define variables and
3879 %code qualifiers, provide macros that retrieve the associated values
3880 and build these lists automatically. Thus Bison will now warn when a
3881 variable or qualifier is not used by the skeleton in the current
3882 invocation regardless of whether it might sometimes be used by that
3883 skeleton in other invocations. Also, move all %define value macros to
3884 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3885 form, which is replaced by %code.
3886 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3887 (b4_check_user_names): ... this, and change the series of valid name
3888 arguments to a single list argument for names used in the skeleton
3889 similar to the existing list argument for names used in the grammar.
3890 Warn instead of complaining.
3891 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3892 values and %code code, to format %code code properly, and to build
3893 lists of all %define variables and %code qualifiers used in the
3894 skeleton: b4_skeleton_percent_define_variables and
3895 b4_skeleton_percent_code_qualifiers.
3896 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
3898 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
3899 the skeleton names lists can finish building first. In place of
3900 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3901 expect the lists b4_user_percent_define_variables and
3902 b4_user_percent_code_qualifiers.
3903 * data/c++.m4: Where setting default values for b4_parser_class_name,
3904 b4_location_type, b4_filename_type, b4_namespace, and
3905 b4_define_location_comparison, update their names to the
3906 b4_percent_define_ namespace.
3907 * data/glr.c: Don't use b4_check_percent_define_variables and
3908 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3909 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
3910 (b4_parser_class_name, b4_namespace): Define these using
3911 b4_get_percent_define for parser_class_name and namespace.
3912 * data/location.cc: Use b4_get_percent_define.
3913 * data/push.c: Don't use b4_check_percent_define_variables and
3914 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3915 * data/yacc.c: Likewise, and don't call m4_exit in
3916 b4_use_push_for_pull_if or m4_wrap code will never execute.
3917 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
3919 (muscle_grow_user_name_list): ... this for consistency with the
3920 terminology used in bison.m4.
3921 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
3922 %define variable names, and rename muscle used_percent_define_variables
3923 to user_percent_define_variables.
3924 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
3925 user_percent_code_qualifiers.
3927 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
3928 {CODE} form is no longer accepted.
3929 * tests/input.at (Reject bad %code qualifiers): Rename to...
3930 (Reject unused %code qualifiers): ... this, and update test output.
3931 (%define error): Update test output.
3933 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
3935 Check for unrecognized %define variables similar to checking for
3936 unrecognized %code qualifiers. Check for redefined %define variables.
3937 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
3939 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
3940 (b4_check_percent_define_variables): New, also wraps it.
3941 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
3942 variables using b4_check_percent_define_variables.
3943 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
3944 all those exercised in the test suite and all those listed in the
3945 `Default values' section of c++.m4. Are there others?
3946 * data/push.c, data/yacc.c: Declare no valid %define variables.
3947 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
3948 similar to muscle_find, but it works even when the muscle stores a
3950 (muscle_grow_used_name_list): New function for constructing the used
3951 name list muscles that b4_check_for_unrecognized_names requires.
3952 * src/parse-gram.y (prologue_declaration): Warn if a variable is
3953 %define'd more than once. Define the b4_used_percent_define_variables
3954 muscle with muscle_grow_used_name_list.
3955 (grammar_declaration): Abbreviate %code code with
3956 muscle_grow_used_name_list.
3957 * tests/input.at (%define errors): New.
3959 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3961 Provide warn_at, complain_at, and fatal_at function callbacks to the
3962 skeletons, and use this for %code qualifier complaints.
3963 * data/bison.m4 (b4_error_at): New, invoked by...
3964 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
3965 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
3966 @fatal_at(...@) directives.
3967 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
3968 qualifiers in b4_used_percent_code_qualifiers and to use
3970 * src/location.c, src/location.h (boundary_set_from_string): New global
3972 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
3974 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
3975 to b4_used_percent_code_qualifiers.
3976 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
3978 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
3979 (lineno): Rename to...
3980 (out_lineno): ... this so I don't misunderstand it again.
3981 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
3982 here; these newlines are in the input but not the output file.
3983 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
3984 (at_directive_perform): ... this new static function, and add handling
3985 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
3987 * tests/input.at (Reject bad %code qualifiers): Update test output with
3988 locations and extend.
3990 * tests/output.at (Output file name: [, Output file name: ]): Remove
3991 bogus comment about these tests failing.
3993 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3995 Clean up b4_check_percent_code_qualifiers a little.
3996 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
3997 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
3998 documentation and add examples.
3999 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
4002 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
4004 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4005 unreliable -- especially when they're hidden inside another macro.
4006 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
4007 data/c.m4: Remove m4_divert(-1).
4008 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4009 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
4010 m4_divert_push(0) and m4_divert_pop(0).
4011 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
4012 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
4013 pushed and popped by m4sugar, should be first on the stack.
4015 Provide warn, complain, and fatal function callbacks to the skeletons.
4016 This provides more flexibility than m4_fatal, improves the error
4017 message format, and captures messages for translation. Discussed
4019 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
4020 * data/bison.m4 (b4_error): New, invoked by...
4021 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
4022 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
4023 directives. Because these M4 macros might be called when the current
4024 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
4025 the previous removal of uses of m4_divert, which caused trouble.
4026 (b4_check_percent_code_qualifiers): Use b4_complain instead of
4027 m4_fatal to report unrecognized %code qualifiers.
4028 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
4029 push parser requests.
4030 * data/glr.c: Use b4_complain instead of m4_fatal to report
4031 non-deterministic push parser requests.
4032 Update @output usage to @output(...@) form.
4033 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
4034 report missing %defines. Update @output usage to @output(...@) form.
4035 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
4037 * src/main.c (main): Invoke skel_scanner_free.
4038 * src/scan-skel.h (skel_scanner_free): Prototype new function.
4039 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
4040 obstack_for_string from flex-scanner.h.
4041 (YY_DECL): Use to declare skel_lex static.
4042 (decode_at_digraphs): Remove; now handled in the new
4043 SC_AT_DIRECTIVE_ARG start condition.
4044 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
4046 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
4047 at_directive_argv): New static globals.
4048 (INITIAL): Use fail_for_invalid_at.
4049 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
4050 recognize the start of a generalized `@directive(...@)' form and
4052 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
4053 directive args (using the new obstack_for_string), to decode the
4054 contained @ diagraphs, and to perform the directive. It recognizes
4055 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
4057 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
4058 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
4060 (scan_skel): Initialize obstack_for_string on the first call.
4061 (skel_scanner_free): New function to free obstack_for_string.
4062 * tests/input.at (Reject bad %code qualifiers): Update test output.
4064 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
4066 Consolidate the 4 prologue alternative directives (%code, %requires,
4067 %provides, and %code-top) into a single %code directive with an
4068 optional qualifier field. Discussed at
4069 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
4070 * NEWS (2.3a+): Rewrite the existing entry for the prologue
4072 * doc/bison.texinfo (Prologue Alternatives): Update.
4073 (Decl Summary): Update to %code "requires" and %code "provides".
4074 (Calc++ Parser): Update to %code "requires".
4075 (Table of Symbols): Remove entries for %requires, %provides, and
4076 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
4077 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
4078 are replaced by b4_percent_code_provides and b4_percent_code_requires,
4079 which are skeleton-specific.
4080 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
4081 declare what %code qualifiers it supports and to complain if any other
4082 qualifiers were used in the grammar.
4083 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
4084 and b4_user_code([b4_percent_code_provides]) in place of
4085 b4_user_requires and b4_user_provides.
4086 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
4087 Add b4_user_code([b4_percent_code_top]) and
4088 b4_user_code([b4_percent_code]).
4089 Invoke b4_check_percent_code_qualifiers.
4090 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4091 PERCENT_REQUIRES): Remove.
4092 (grammar_declaration): Remove RHS's for %code-top, %provides, and
4093 %requires. Rewrite the %code RHS as the unqualified form defining the
4094 muscle b4_percent_code. Add another RHS for the qualified %code form,
4095 which defines muscles of the form b4_percent_code_QUALIFIER and the
4096 b4_used_percent_code_qualifiers muscle.
4097 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4098 PERCENT_REQUIRES): Remove.
4099 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
4100 %code "requires" and %code "provides".
4101 * tests/input.at (Reject bad %code qualifiers): New.
4103 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4105 Use the new code_props interface for destructors and printers.
4106 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
4107 printer_location members, and change the type of the destructor and
4108 printer members to code_props.
4109 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
4110 symbol_printer_get, semantic_type_destructor_set,
4111 semantic_type_printer_set, default_tagged_destructor_set,
4112 default_tagless_destructor_set, default_tagged_printer_set,
4113 default_tagless_printer_set): Use code_props in arguments and return
4114 types in place of char const * and location.
4115 (symbol_destructor_location_get, symbol_printer_location_get): Remove
4116 since the locations are now contained in the return of
4117 symbol_destructor_get and symbol_printer_get.
4118 * src/output.c (symbol_destructors_output, symbol_printers_output):
4120 (symbol_code_props_output): ... this to eliminate duplicate code.
4121 (output_skeleton): Update to use symbol_code_props_output.
4122 * src/reader.c (symbol_should_be_used): Update use of
4123 symbol_destructor_get.
4124 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4125 Update uses of the various _destructor_set and _printer_set functions.
4126 * src/symtab.c: (default_tagged_destructor_location,
4127 default_tagless_destructor_location, default_tagged_printer_location,
4128 default_tagless_printer_location): Remove since we...
4129 (default_tagged_destructor, default_tagless_destructor,
4130 default_tagged_printer, default_tagless_printer): ... change the type
4131 of these to code_props.
4132 (symbol_new, semantic_type_new, symbol_destructor_set,
4133 semantic_type_destructor_set, symbol_destructor_get,
4134 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
4135 symbol_check_alias_consistency, default_tagged_destructor_set,
4136 default_tagless_destructor_set, default_tagged_printer_set,
4137 default_tagless_printer_set): Update.
4138 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4139 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4141 (symbol_print): Use SYMBOL_CODE_PRINT.
4143 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4145 Use the new code_props interface for rule actions.
4146 * src/symlist.h (symbol_list): Replace action, action_location, and
4147 used members with a code_props action_props member.
4148 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4149 grammar_midrule_action, grammar_current_rule_merge_set,
4150 grammar_current_rule_symbol_append, packgram): Update.
4151 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4152 * src/scan-code.l (handle_action_dollar): Update.
4153 (translate_rule_action): Remove, no longer used.
4154 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4156 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4158 Use the new code_props interface in parse-gram.y.
4159 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
4160 Update all uses of translate_* functions to use the new code_props
4161 interface and to use gram_scanner_last_string_free and
4162 code_scanner_last_string_free where possible.
4163 (grammar_declaration): symbol_list_destructor_set and
4164 symbol_list_printer_set now perform the translation, so don't do it
4165 here. Use gram_scanner_last_string_free where possible.
4166 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
4167 translate_code): Remove, no longer used.
4168 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
4169 symbol_list_printer_set): Perform code translation here rather than
4170 depending on the caller to do so.
4172 * src/symlist.h (struct symbol_list): Correct some documentation typos.
4173 * src/scan-gram.h (gram_last_string): Remove declaration.
4174 * src/scan-gram.l (last_string): Declare it static.
4176 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4178 Encapsulate code properties and related functionality for the various
4179 destructors, printers, and actions into a code_props structure and
4180 interface. This patch merely implements code_props in scan-code.h and
4181 scan-code.l. Future patches will rewrite other modules to use it.
4182 Discussed starting at
4183 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4184 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4185 consistently initialize const structs that have an empty location
4187 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4188 to ensure consistency.
4189 * src/scan-code.h (code_props): New structure.
4190 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4191 function, macro, and const global variable for initializing a
4192 code_props with no code.
4193 (code_props_plain_init, code_props_symbol_action_init,
4194 code_props_rule_action_init, code_props_translate_code): The rest of
4195 the new code_props functional interface. Among other things, the init
4196 functions set the code_props kind field so that
4197 code_props_translate_code will know whether to behave like
4198 translate_symbol_action, translate_rule_action, or translate_code.
4199 These old translate functions must remain until all other modules are
4200 updated to use the new code_props interface.
4201 (code_scanner_last_string_free): New function similar to
4202 gram_scanner_last_string_free.
4203 (code_scanner_free): Add documentation.
4204 * src/scan-code.l: Implement the new interface.
4205 (code_lex): Make it static, add a code_props* argument, and remove the
4207 (last_string): New static global similar to the one in scan-gram.l.
4208 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4210 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4211 code_props since Bison may one day use this information for destructors
4213 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4214 (handle_action_dollar): Use symbol_list_n_get and set used flag
4215 directly since symbol_list_n_used_set is removed.
4216 (translate_action): Add a code_props* argument and remove the rule,
4217 action, and location arguments. Pass the code_props* on to code_lex.
4218 (translate_rule_action, translate_symbol_action, translate_code):
4219 Rewrite as wrappers around the new code_props interface.
4220 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
4221 it would eventually need to break the encapsulation of code_props.
4223 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4225 * etc/.cvsignore: New.
4227 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4229 Add maintainer-push-check to run maintainer-check using push parsing in
4230 place of pull parsing where available.
4231 * Makefile.am (maintainer-push-check): New.
4232 * data/bison.m4 (b4_use_push_for_pull_if): New.
4233 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
4234 appropriately based on their existing values.
4235 (yypush_parse): Don't print push-parser-specific diagnostics if push
4236 parsing is being used in place of pull parsing.
4237 * data/yacc.c: If push parsing should replace pull parsing, redirect to
4239 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
4240 variable, and insert b4_use_push_for_pull_flag into muscles.
4241 * tests/Makefile.am (maintainer-push-check): New.
4243 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4245 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
4246 (whether successful or failed) so that yypush_parse can be invoked
4247 again to start a new parse using the same yypstate.
4248 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
4249 check multiple yypull_parse invocations on the same yypstate. For pull
4250 mode, extend to check multiple yyparse invocations.
4251 (Exploding the Stack Size with Alloca): Extend to try with
4253 (Exploding the Stack Size with Malloc): Likewise.
4255 * tests/calc.at (Simple LALR Calculator): Don't specify
4256 %skeleton "push.c" since %push-pull-parser implies that now.
4257 * tests/headers.at (export YYLTYPE): Don't check for the push
4258 declarations. Otherwise, this test case can't be used to see if push
4259 mode can truly emulate pull mode.
4260 * tests/input.at (Torturing the Scanner): Likewise.
4261 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
4262 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
4263 AT_YACC_IF, which now includes the case of push mode since %skeleton
4264 need not be used for push mode. This will be more intuitive once
4265 push.c is renamed to yacc.c.
4267 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4269 For push mode, convert yyparse from a macro to a function, invoke yylex
4270 instead of passing a yylexp argument to yypull_parse, and don't
4271 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4272 Discussed starting at
4273 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4274 * data/bison.m4 (b4_pull_if): New.
4275 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4276 * data/push.c: Improve M4 quoting a little.
4277 (b4_generate_macro_args, b4_parenthesize): Remove.
4278 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4279 any time a pull parser is requested.
4280 Don't #define this as a wrapper around yypull_parse. Instead, when
4281 both push and pull are requested, make it a function that does that
4283 (yypull_parse): If there's a b4_prefix, #define this to
4284 b4_prefix[pull_parse] when both push and pull are requested.
4285 Don't define this as a function unless both push and pull are
4287 Remove the yylexp argument and hard-code yylex invocation instead.
4288 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4290 * src/getargs.c (pull_parser): New global initialized to true.
4291 * getargs.h (pull_parser): extern it.
4292 * src/output.c (prepare): Insert pull_flag muscle.
4293 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4294 (prologue_declaration): Set both push_parser and pull_parser = true for
4295 %push-pull-parser. Set push_parser = true and pull_parser = false for
4297 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4298 %push-parser since there's no backward-compatibility concern here.
4299 Scan %push-pull-parser.
4300 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4301 instead of %push-parser.
4302 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4303 prototype it in the module that calls yyparse.
4304 * tests/input.at (Torturing the Scanner): Likewise.
4305 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4307 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4309 Update etc/bench.pl. Optimize push mode a little (the yyn change
4310 deserves most of the credit).
4311 * Makefile.am (SUBDIRS): Add etc subdirectory.
4312 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4313 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4314 yytoken, yyval, and yyloc declarations to...
4315 (yyparse or yypush_parse): ... here to improve performance. For
4316 yypush_parse invocations after the first, be sure to assign yyn its old
4318 (yypstate_new): Don't bother initializing the yyresult field since the
4319 initial value isn't used.
4320 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4321 remove the #define that, in push mode, set it to yyps->NAME.
4322 * etc/Makefile.am: New.
4323 * etc/bench.pl: Remove and build it instead from...
4324 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4325 "tests/bison" from the build directory by default rather than just
4326 invoking "bison" from $PATH.
4327 (calc_grammar): Update push parser code: don't declare yylval globally,
4328 don't define yyparse_wrapper, and don't #define yyparse.
4329 (bench_grammar): Update to check all working combinations of yacc.c,
4330 push.c, impure, pure, pull, and push.
4332 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4334 For push mode, add pull wrappers around yypush_parse.
4335 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4336 (yypull_parse): New function wrapping yypush_parse.
4337 (yyparse): New #define wrapping yypull_parse.
4338 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4340 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4341 prototype yylex in the module that calls yyparse, and don't prototype
4342 yyparse there. Otherwise, the yyparse expansion won't compile.
4343 * tests/input.at (Torturing the Scanner): Likewise.
4345 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4347 Enable push parsers to operate in impure mode. Thus, %push-parser no
4348 longer implies %pure-parser. The point of this change is to move
4349 towards being able to test the push parser code by running the entire
4350 test suite as if %push-parser had been declared.
4351 * data/push.c (yypush_parse): For impure mode, remove the
4352 yypushed_char, yypushed_val, and yypushed_loc arguments.
4353 Instead, declare these as local variables initialized to the global
4354 yychar, yylval, and yylloc.
4355 For the first yypush_parse invocation only, restore the initial values
4356 of these global variables when it's time to read a token since they
4357 have been overwritten.
4358 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4360 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4361 %pure-parser along with %push-parser since this test case was designed
4362 for pure push parsers.
4363 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4364 (AT_YACC_OR_PUSH_IF): New.
4365 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4366 add a note that it's still wrong for some cases (as it has been for a
4368 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4369 %push-parser no longer implies %pure-parser.
4371 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4373 Remove some unnecessary differences between the pull parser code and
4374 the push parser code. This patch enables yynerrs in push mode.
4375 * data/push.c: Reformat M4 a little.
4376 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4377 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
4378 because push mode is on. Instead, if pure mode is on, move yynerrs
4380 (b4_declare_parser_state_variables): ... here.
4381 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
4382 to yyps->NAME so it can be used in yypush_parse.
4383 (yypush_parse): Don't omit uses of yynerrs in push mode.
4385 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4387 Fix bug such that the first pushed token's value and location are
4388 sometimes overwritten (sometimes by %initial-action) before being used.
4389 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
4390 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4391 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4392 more closely mimic the pull parser logic.
4393 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4394 time to read a token, which is after any initialization of yylval and
4396 (gottoken): Rename label to...
4397 (yyread_pushed_token): ... for clarity and to avoid infringing on the
4400 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4402 Rearrange initialization of the parser state variables so that the
4403 skeleton doesn't have to have a copy for pull mode and another for push
4404 mode. This patch also fixes at least a bug such that yylloc was not
4405 initialized (with b4_location_initial_line and
4406 b4_location_initial_column) upon calling yypush_parse. However, that
4407 initialization now overwrites the first token's location;
4408 %initial-action assigning @$ already did the same thing, and both bugs
4409 will be fixed in a later patch.
4410 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4411 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4412 yyss, yyvs, yyls, and yystacksize.
4413 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4414 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4416 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4417 yyps->NAME so it can be used in yypush_parse.
4418 (yyparse or yypush_parse): For yypush_parse, don't print the
4419 "Starting parse" diagnostic for invocations after the first.
4420 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4421 yypush_parse, only do it for the first invocation.
4422 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4423 initialization to occur in yypush_parse but only on the first
4426 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4428 * data/push.c: Add CPP guards around push parser declarations in both
4429 the header and the code file.
4430 In the code file, move the push parser declarations to the same place
4431 they appear in the header file.
4432 Clean up the M4 some, especially the inconsistent underquoting in
4433 some b4_c_function_def and b4_c_function_decl uses.
4435 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4437 Encapsulate the push parser state variables into an M4 macro so the
4438 push skeleton doesn't have to list them again for pull mode's yyparse.
4439 For push mode, remove yypush_parse's local equivalents of these
4440 variables to eliminate unnecessary copying between the two sets at
4441 run-time. This patch also fixes at least a bug related to multiple
4442 %initial-action invocations in push mode.
4443 * data/push.c (b4_declare_parser_variables): Rename to...
4444 (b4_declare_scanner_communication_variables): ... this for clarity and
4446 (b4_declare_yyparse_variables): Remove and move its contents to the one
4447 spot where it was invoked.
4448 (b4_declare_parser_state_variables): New macro containing the parser
4449 state variables required by push mode.
4450 (struct yypstate): Replace all fields but yynew with
4451 b4_declare_parser_state_variables.
4452 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4453 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4454 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4455 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4456 parser state variable declarations with
4457 b4_declare_parser_state_variables.
4458 Don't initialize parser state variables when calling yypush_parse since
4459 yypstate_new already does that.
4460 Invoke the user's initial action only upon the first yypush_parse
4462 Remove all code that copies between the local parser state variables
4465 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4467 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
4468 prevent a name collision in a future patch where these names will
4469 sometimes be #define'd.
4470 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
4471 since it no longer has the same name as the existing argument.
4472 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
4474 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
4475 and Joel E. Denny <jdenny@ces.clemson.edu>
4477 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
4478 that the argument is case-insensitive, and there's no `=' here.
4479 For the %skeleton entry, mention that %language is better.
4480 (Bison Options): Likewise for --language and --skeleton. Move the
4481 --skeleton entry so that the `Tuning the parser' section is sorted
4482 alphabetically on long options.
4483 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
4484 %language directive in detail here; cross-reference the %language
4485 documentation instead.
4486 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
4487 `%require "2.3b"' so that the example is always up-to-date.
4488 (Table of Symbols): Add entries for %language and %skeleton.
4489 * examples/extexi (normalize): Instead of replacing every %require
4490 argument with the current Bison version, just substitute for
4491 `@value{VERSION}'. This guarantees that we're testing what actually
4492 appears in the documentation.
4493 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
4494 rather than `@VERSION@'.
4496 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4498 * NEWS: Reword the %language news a bit, and put it earlier.
4500 * src/getargs.c (skeleton_arg): Last arg is now location const *.
4501 Rewrite to simplify the logic.
4502 (language_argmatch): Likewise.
4503 (program_name): We now own this var.
4504 * src/getargs.h (struct bison_language): Use char[] rather than
4507 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
4509 * src/complain.c (program_name): Remove decl; no longer needed.
4510 * src/main.c (program_name): Remove; now belongs to getargs.
4512 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
4514 * NEWS: Document %language.
4516 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
4518 * data/c-skel.m4, data/c++-skel.m4: New files.
4519 * data/glr.c: Complain on push parsers.
4521 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
4523 (Decl Summary): Document %language and %skeleton.
4524 (Command line): Document -L.
4526 * examples/extexi: Rewrite %require directive.
4527 * examples/calc++/Makefile.am: Pass VERSION to extexi.
4529 * src/files.c (compute_exts_from_gc): Look in language structure
4531 (compute_file_name_parts): Check whether .tab should be added.
4532 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
4533 (language, skeleton_arg, language_argmatch): New.
4534 (long_options): Add --language.
4535 (getargs): Use skeleton_arg, add -L/--language.
4536 * src/getargs.h: Include location.h.
4537 (struct bison_language, language, skeleton_arg, language_argmatch): New.
4538 * src/output.c (prepare): Pick default skeleton from struct language.
4539 Don't dispatch C skeletons here.
4540 * src/parse-gram.y (PERCENT_LANGUAGE): New.
4541 (prologue_declaration): Add "%language" rule, use skeleton_arg.
4542 * src/scan-gram.l ("%language"): New rule.
4544 * tests/calc.at: Test %skeleton and %language.
4545 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
4546 (AT_GLR_IF): Look for %skeleton "glr.cc".
4547 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
4548 (AT_YACC_IF): Reject %language.
4550 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4552 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
4553 since it wasn't used; only the typedef name 'semantic_type' is needed.
4554 Also, omit trailing white space.
4556 * bootstrap: Sync from coreutils.
4557 (gnulib_extra_files): Add build-aux/announce.gen.
4558 (slurp): Adjust .gitignore files like .cvsignore files.
4559 * build-aux/announce-gen: Remove from CVS, since bootstrap
4562 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
4564 Make %push-parser imply %pure-parser. This fixes several bugs; see
4565 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
4566 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
4568 * data/push.c: Don't bother testing b4_push_if when deciding whether
4569 to expand b4_declare_parser_variables globally.
4570 (yypush_parse): Likewise in here.
4572 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
4573 (yy_reduce_print): Reformat M4 for readability.
4575 2006-12-15 Bob Rossi <bob@brasko.net>
4576 and Joel Denny <jdenny@ces.clemson.edu>
4578 * data/push.c (yypstate): Add typedef, and update all uses of
4579 struct yypstate to just yypstate.
4580 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
4582 2006-12-14 Bob Rossi <bob@brasko.net>
4584 * data/push.c (yypush_parse): Declare prototype regardless of
4587 2006-12-14 Bob Rossi <bob@brasko.net>
4589 * data/push.c (yyparse): Remove the prototype and the #define when in
4592 2006-12-13 Bob Rossi <bob@brasko.net>
4594 * data/push.c (yypstate_init): Rename to...
4595 (yypstate_new): ... this and use b4_c_function_def.
4596 (yypstate_delete): New.
4597 (yypush_parse): Change parameters yynval and yynlloc to be const.
4598 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
4599 yypstate_delete functions.
4601 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
4603 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
4604 strange test case titles. Reported by Bob Rossi.
4606 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
4608 * TODO: Add pointer to Sylvain Schmitz's work on static detection
4609 of potential ambiguities in GLR grammers.
4611 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
4613 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
4614 `bison ', use m4_index instead of m4_substr since chopping up a string
4615 containing M4-special characters causes problems here.
4617 Fix a couple of bugs related to special characters in user-specified
4618 file names, and make it easier for skeletons to compute output file
4619 names with the same file name prefix as Bison-computed output file
4621 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
4622 b4_parser_file_name and b4_spec_defines_file instead of
4623 @output_parser_name@ and @output_header_name@, which are now redundant.
4624 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4625 b4_parser_file_name, b4_spec_defines_file, and the new
4626 @basename(FILENAME@) instead of @output_parser_name@ and
4627 @output_header_name@, which inappropriately escaped the file names as
4629 * src/files.c (all_but_ext): Remove static qualifier.
4630 (compute_output_file_names): Move `free (all_but_ext)' to...
4631 (output_file_names_free): ... here since all_but_ext is needed later.
4632 * src/files.h (all_but_ext): Extern.
4633 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4634 exactly what MUSCLE_INSERT_STRING used to do.
4635 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
4636 characters are escaped properly.
4637 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4639 For pkgdatadir muscle, maintain previous functionality by using
4640 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4641 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4642 digraphs would never be expanded. Hopefully no one has M4-special
4643 characters in his Bison installation path.
4644 * src/scan-skel.l: Don't parse @output_header_name@ and
4645 @output_parser_name@ anymore since they're now redundant.
4646 In @output, use decode_at_digraphs.
4647 Parse a new @basename command that invokes last_component.
4648 (decode_at_digraphs): New.
4649 (BASE_QPUTS): Remove unused.
4650 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
4651 (Output file name): New tests.
4653 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
4655 Warn about output files that are generated by the skeletons and that
4656 conflict with other output files.
4657 * data/glr.c: Don't generate the header file here when glr.cc does.
4658 * src/files.c (file_names, file_names_count): New static globals.
4659 (compute_output_file_names): Invoke output_file_name_check for files
4660 not generated by the skeletons and remove existing checks.
4661 (output_file_name_check): New function that warns about conflicting
4663 (output_file_names_free): Free file_names.
4664 * src/files.h (output_file_name_check): Declare.
4665 * src/scan-skel.l: Invoke output_file_name_check for files generated by
4667 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
4668 (Conflicting output files): New tests.
4670 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4672 * doc/bison.texinfo: Fix a couple of typos.
4674 2006-12-08 Bob Rossi <bob@brasko.net>
4676 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
4678 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
4680 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
4681 (yypush_parse): Rename yypvars argument to yyps and remove redundant
4683 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
4684 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
4686 2006-12-07 Bob Rossi <bob@brasko.net>
4687 and Joel Denny <jdenny@ces.clemson.edu>
4689 * data/push.c (yypvarsinit): Change return type from void* to struct
4690 yypvars*. No longer cast to void* on return.
4691 (struct yypvars): Remove yylen since it need not be remembered between
4692 yypushparse invocations.
4693 (yypushparse): Don't copy between yylen and pv->yylen.
4695 2006-12-05 Bob Rossi <bob@brasko.net>
4697 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
4698 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
4699 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
4700 (struct yypvars): Remove b4_declare_parser_variables.
4701 (yypvarsinit): Remove init code for removed variables.
4702 (global scope): Do not declare b4_declare_parser_variables if
4704 (yypushparse): Add b4_declare_parser_variables.
4705 Init new local variables, and remove init code for removed
4708 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
4709 and yyparse for other modes.
4710 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
4711 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
4712 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
4713 (AT_PURE_LEX_IF): True if pure or push parser.
4715 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

4796 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
4797 later. Reported by Paul Eggert in

4814 --enable-gcc-warnings doesn't produce warnings that the return discards
4815 const. aver that the value and storage are the same since storage
4816 could potentially be NULL when value is not.
4817 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
4820 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4822 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
4823 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
4824 us a slightly cleaner distribution, and also works.
4825 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
4828 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
4829 and Paul Eggert <eggert@cs.ucla.edu>
4831 Don't let Bison leak memory except when it complains.
4832 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
4833 (spec_defines_file, dir_prefix): Now char *, not const char *,
4834 since they are freed.
4835 * src/files.c: Likewise.
4836 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
4838 (tr): Now operates in-place. All uses changed.
4839 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
4841 (compute_file_name_parts, compute_output_file_names): Don't store
4842 read-only data in variables that will be freed.
4843 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
4844 src_extension, and header_extension.
4845 (output_file_names_free): New public function to free
4846 spec_verbose_file, spec_graph_file, spec_defines_file,
4847 parser_file_name, and dir_prefix.
4848 * src/getargs.c (getargs): Don't store read-only data in variables that
4850 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
4851 (which previously existed but was unused), and quotearg_free.
4852 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
4853 * src/muscle_tab.c: Likewise.
4854 (muscle_entry): Make the value char const *,
4855 and add a new storage member that is char * and can be freed.
4856 (muscle_entry_free): New private function.
4857 (muscle_init): Use it instead of free.
4858 (muscle_insert, muscle_grow): Update and use new storage member.
4859 (muscle_code_grow): Free the string passed to muscle_grow
4860 since it's not needed anymore.
4861 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
4862 add a new `char *code' member.
4863 ("{...}"): Declare semantic type as code.
4864 * src/scan-code.h (translate_rule_action):
4865 (translate_symbol_action, translate_code, translate_action): Return
4866 `char const *' rather than `char *' since external code should not free
4868 * src/scan-code.l: Likewise.
4869 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
4870 which is "{...}" in the parser.
4871 * tests/Makefile.am (maintainer-check-valgrind): Set
4872 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
4874 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
4876 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
4877 expecting a non-zero exit status sets --leak-check=summary and
4878 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
4879 this case, and we don't want to hear about it.
4881 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4883 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
4884 instead of from the template, to simplify configuration a bit.
4885 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
4886 and m4/wint_t.m4, as they are needed with the latest gnulib.

4900 declarations): Run tests with and without --warnings=midrule-values.
4902 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
4903 than LIST_FREE directly.
4905 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

4924 empty subargument list. For example: `bison --warnings= parser.y'.
4926 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4928 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
4929 the parser header file so that gcc doesn't warn.
4931 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4933 Split the default %destructor/%printer into two kinds: <*> and <!>.

4979 Don't apply the default %destructor/%printer to an unreferenced midrule
4981 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
4982 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
4983 like $@n instead of just @n so that the default %destructor/%printer
4984 logic doesn't see them as user-defined symbols.
4985 (symbol_is_dummy): Check for both forms of the name.
4986 * src/reader.c (packgram): Remove the `$' from each midrule symbol
4987 name for which the midrule value is referenced in any action.

4998 (packgram): Before invoking grammar_rule_check on any rule, make sure
4999 all actions have already been scanned in order to set `used' flags.
5000 Otherwise, checking that a midrule's $$ is set will not always work
5001 properly because the midrule check must forward-reference the midrule's

5015 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
5017 Similar to the recently removed %before-header, add %code-top as the
5018 alternative to the pre-prologue. Mentioned at
5019 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.

5085 Fix testsuite for ./configure --enable-gcc-warnings:
5086 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.

5123 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
5124 Include <config.h> unconditionally.
5126 * bootstrap: Sync from coreutils, as follows:
5128 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
5130 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
5131 variable was sometimes used without being initialized. This
5132 messed up the installation of the INSTALL file in some cases.
5134 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5136 * bootstrap (usage, main program, symlink_to_gnulib): Add option
5137 --copy. Inspired by a suggestion from Bruno Haible.
5139 2006-10-03 Jim Meyering <jim@meyering.net>
5141 * bootstrap: Undo last change to this file, since now gnulib-tool
5142 sticks with the automake default in generating dependencies.
5144 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5146 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

5237 Fix problems with translating English-language diagnostics.
5238 * bootstrap: Fix bug introduced in recent bootstrap changes, with

5240 wasn't being captured.
5241 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
5242 * po/POTFILES.in: Add src/location.c, src/scan-code.l.

5249 2006-09-28 Jim Meyering <jim@meyering.net>
5251 Automatically generated dependencies are important even
5252 when all of the sources in a directory come from gnulib.
5253 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
5254 option that gnulib-tool adds to what becomes our lib/gnulib.mk.

5270 Adjust white space and comments to match GNU style better.
5272 2006-09-20 Bob Rossi <bob@brasko.net>
5274 * data/push.c (yyresult_get): Remove function.
5275 (YYPUSH_MORE): Add #define.
5276 (yypushparse): Modify return value.
5278 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5280 * stamp-h.in: Remove; no longer needed.
5281 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
5282 Remove config.h, config.hin, intl (no longer created).
5283 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
5286 Sync bootstrap from coreutils, as follows:
5288 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
5290 * bootstrap (symlink_to_gnulib): New function.
5291 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
5292 to copies-of-gnulib.
5293 (cp_mark_as_generated, slurp, gnulib_files):
5294 Avoid making a copy if it's the same as the old version.
5295 (gnulib_files): Add support for this variable (used by Bison).
5297 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5299 * src/getargs.c (usage): Rework to use conventions similar to
5300 coreutils, to make translation a bit easier and the code a bit
5301 smaller. Problem reported by Tim Van Holder.
5303 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
5305 Use some of gnulib's new modules, taken from coreutils.
5307 * bootstrap: Sync from coreutils, except add support for gnulib_files.
5308 * bootstrap.conf: New file.
5309 (gnulib_modules): Add configmake, inttypes, unistd.
5310 (XGETTEXT_OPTIONS): Add complain, complain_at,
5311 fatal, fatal_at, warn, warn_at, unexpected_end.
5312 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
5313 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
5315 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
5317 (GNULIB_AUTOCONF_SNIPPET): Remove.
5318 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
5320 * lib/.cvsignore: Add inttypes_.h.
5321 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
5322 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
5323 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
5324 no-longer-necessary initializations.
5325 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
5326 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
5327 use the unistd module.
5328 * src/system.h: Likewise.
5329 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5330 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5331 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5332 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5333 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5334 * src/system.h: Include inttypes.h unconditionally, now that we
5335 use the inttypes module. Don't bother to include stdint.h, since
5336 inttypes.h now does that for us.
5337 (LOCALEDIR): Remove, now that we use the configmake module.
5338 * src/getargs.c: Include configmake.h.
5339 * src/main.c: Likewise.
5340 * src/output.c: Likewise.
5341 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5342 not from $abs_top_builddir, since config.h moved.
5345 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5346 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5348 * src/parse-gram.y (symbol_declaration): Don't put statements
5349 before declarations; it's not portable to C89.
5350 * src/scan-code.l (handle_action_at): Likewise.
5352 * src/scan-code.l: Always initialize braces_level; the old code
5353 left it uninitialized and therefore had undefined behavior.
5355 Don't attempt to redefine 'assert', since it runs afoul of
5356 systems where standard headers (mistakenly) include <assert.h>.
5357 Instead, define and use our own alternative, called 'aver'.
5358 * src/reader.c: Don't include assert.h, since we no longer
5360 * src/scan-code.l: Likewise.
5361 * src/system.h (assert): Remove, replacing with....
5362 (aver): New function, taking a bool arg. All uses changed.
5363 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5364 not merely an integer.
5366 2006-09-15 Bob Rossi <bob@brasko.net>
5368 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5369 * data/c.m4 (YYPUSH): New.
5370 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
5371 * src/getargs.c (push_parser): New var.
5372 * src/getargs.h (push_parser): New declaration.
5373 * src/output.c (prepare): Add macro insertion of `push_flag'.
5374 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5375 (prologue_declaration): Parse %push-parser.
5376 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5377 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
5378 list of removed lines from the traces observed.
5379 (AT_CHECK_CALC_LALR): Added push parser tests.
5381 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
5383 * NEWS: Version 2.3a.
5384 * configure.ac (AC_INIT): Likewise.
5386 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
5387 "#define YYSTYPE int" that caused "make maintainer-check" to fail
5388 due to header ordering dependencies. I don't know why the #define
5391 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
5392 runtime cost when YYDEBUG is not defined, and so that some tests
5393 that used to fail now work. Problem and initial suggestion by
5395 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
5396 * data/glr.cc (b4_parser_class_name):
5397 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
5398 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
5399 (yydebug_) [YYDEBUG]: New member.
5400 (yycdebug_): Now defined only if YYDEBUG.
5401 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
5402 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
5403 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
5405 (debug_stream, set_debug_stream, debug_level, set_debug_level):
5406 Define only if YYDEBUG.
5407 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
5409 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
5410 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
5411 AT_CHECK_CALC_GLR_CC that are working now.
5413 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5415 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
5416 We don't need them in glr.cc, and glr.c defines them.
5417 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
5418 assumes that defining it to anything is the same as defining
5419 it to 1. Problem reported by Paolo Bonzini.
5421 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
5423 * data/c.m4 (b4_null, b4_case): Define.
5424 * src/output.c (prepare_symbols): Use b4_null.
5425 (user_actions_output): Use b4_case.
5427 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
5429 * data/glr.c (b4_shared_declarations): Put start-header first,
5430 before any #includes that we generate, so that feature-test
5431 macros work. Problem reported by Michael Deutschmann in
5432 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
5433 * data/lalr1.cc: Likewise.
5434 * doc/bison.texinfo (Prologue): Document that feature-test macros
5435 should be defined before any Bison declarations.
5436 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
5437 that depend on location.hh after, not before, Bison decls, since
5438 we now include location.hh after the first user prologue.
5440 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
5441 Sander Brandenburg in
5442 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
5443 Also, fix minor white space and comment issues.
5444 (Prologue): Mention that it's better to define feature-test macros
5445 before Bison declarations. Problem reported by Michael Deutschmann.
5447 * README-cvs: Fix typo: "&" should be "&&". Problem reported
5449 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
5450 This adjusts to recent gnulib changes.
5452 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5454 Finish implementation of per-type %destructor/%printer. Discussed
5456 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
5458 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
5459 * NEWS (2.3+): Add a description of this feature to the default
5460 %destructor/%printer description.
5461 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
5462 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5463 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
5464 list node contains a semantic type.
5465 * src/symtab.c, src/symtab.h: Extend with a table that associates
5466 semantic types with their %destructor's and %printer's.
5467 (semantic_type_from_uniqstr, semantic_type_get,
5468 semantic_type_destructor_set, semantic_type_printer_set): New functions
5469 composing the public interface of that table.
5470 (symbol_destructor_get, symbol_destructor_location_get,
5471 symbol_printer_get, symbol_printer_location_get): If there's no
5472 per-symbol %destructor/%printer, look up the per-type before trying
5474 * tests/actions.at (Per-type %printer and %destructor): New test case.
5475 * tests/input.at (Default %printer and %destructor redeclared):
5476 Extend to check that multiple occurrences of %symbol-default in a
5477 single %destructor/%printer declaration is an error.
5478 (Per-type %printer and %destructor redeclared, Unused values with
5479 per-type %destructor): New test cases.
5481 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5483 Require default %destructor/%printer to be declared using
5484 %symbol-default instead of an empty symbol list, and start working on
5485 new per-type %destructor/%printer. Discussed at
5486 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
5487 * NEWS (2.3+): Add %symbol-default to example.
5488 * bison.texinfo (Freeing Discarded Symbols): Likewise.
5489 (Table of Symbols): Add entry for %symbol-default.
5490 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
5491 (generic_symlist, generic_symlist_item): New nonterminals for creating
5492 a list in which each item is a symbol, semantic type, or
5494 (grammar_declaration): Use generic_symlist in %destructor and %printer
5495 declarations instead of symbols.1 or an empty list.
5496 (symbol_declaration, precedence_declaration, symbols.1): Update actions
5497 for changes to symbol_list.
5498 * src/reader.c: Update for changes to symbol_list.
5499 * src/scan-code.l: Likewise.
5500 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
5501 * src/symlist.c, src/symlist.h: Extend such that a list node may
5502 represent a semantic type or a %symbol-default in addition to just an
5503 ordinary symbol. Add switched functions for setting %destructor's and
5505 * tests/actions.at, tests/input.at: Add %symbol-default to all default
5506 %destructor/%printer declarations.
5508 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
5510 Whether the default %destructor/%printer applies to a particular symbol
5511 isn't a question of whether the user *declares* that symbol (in %token,
5512 for example). It's a question of whether the user by any means
5513 *defines* the symbol at all (by simply using a char token, for
5514 example). $end is defined by Bison whereas any other token with token
5515 number 0 is defined by the user. The error token is always defined by
5516 Bison regardless of whether the user declares it with %token, but we
5517 may one day let the user define error as a nonterminal instead.
5518 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
5519 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
5520 the meaning of "user-defined".
5521 * tests/actions.at (Default %printer and %destructor for user-declared
5522 end token): Rename to...
5523 (Default %printer and %destructor for user-defined end token): ...
5526 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
5527 computation of whether to apply the default, don't maintain a list of
5528 every Bison-defined symbol. Instead, just check for a first character
5529 of '$', which a user symbol cannot have, and check for the error token.
5531 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
5533 Don't apply the default %destructor or %printer to the error token,
5534 $undefined, or $accept. This change fits the general rule that the
5535 default %destructor and %printer are only for user-declared symbols,
5536 and it solves several difficulties that are described in the new test
5538 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
5539 * tests/actions.at (Default %printer and %destructor are not for error
5540 or $undefined, Default %printer and %destructor are not for $accept):
5543 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
5545 Allow %start after the first rule.
5546 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
5547 when parsing the first rule.
5548 (check_and_convert_grammar): Search for it here after all grammar
5549 declarations have been parsed. Skip midrules, which have dummy LHS
5551 * src/symtab.c (symbol_is_dummy): New function.
5552 * src/symtab.h (symbol_is_dummy): Declare it.
5553 * tests/input.at (%start after first rule): New test.
5555 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5557 Redo some of the previous commit: add back the ability to use
5558 non-aliased/undeclared string literals since it might be useful to
5559 those declaring %token-table.
5560 * src/reader.c (check_and_convert_grammar): Undo changes in previous
5561 commit: don't worry about complaints from symbols_pack.
5562 * src/symtab.c (symbol_new, symbol_class_set,
5563 symbol_check_alias_consistency): Undo changes in previous commit: count
5564 each string literal as a new symbol and token, assign it a symbol
5565 number, and don't complain about non-aliased string literals.
5566 (symbols_pack): Since symbol_make_alias still does not decrement symbol
5567 and token counts but does still set aliased tokens to the same number,
5568 symbol_pack_processor now leaves empty slots in the symbols array.
5570 * tests/regression.at (Undeclared string literal): Remove test case
5571 added in previous commit since non-aliased string literals are allowed
5573 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
5574 remove unnecessary string literal declarations.
5575 * tests/sets.at (Firsts): Likewise.
5577 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5579 Don't allow an undeclared string literal, but allow a string literal to
5580 be used before its declaration.
5581 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
5582 symbols_pack complained.
5583 * src/symtab.c (symbol_new): Don't count a string literal as a new
5585 (symbol_class_set): Don't count a string literal as a new token, and
5586 don't assign it a symbol number since symbol_make_alias does that.
5587 (symbol_make_alias): It's not necessary to decrement the symbol and
5588 token counts anymore. Don't assume that an alias declaration occurs
5589 before any uses of the identifier or string, and thus don't assert that
5590 one of them has the highest symbol number so far.
5591 (symbol_check_alias_consistency): Complain if there's a string literal
5592 that wasn't declared as an alias.
5593 (symbols_pack): Bail if symbol_check_alias_consistency failed since
5594 symbol_pack asserts that every token has been assigned a symbol number
5595 although undeclared string literals have not.
5596 * tests/regression.at (String alias declared after use, Undeclared
5597 string literal): New test cases.
5598 (Characters Escapes, Web2c Actions): Declare string literals as
5600 * tests/sets.at (Firsts): Likewise.
5602 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
5604 In the grammar scanner, STRING_FINISH unclosed constructs and return
5605 them to the parser in order to improve error messages.
5606 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
5607 SC_BRACED_CODE, SC_PROLOGUE): Implement.
5608 * tests/input.at (Unclosed constructs): New test case.
5609 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
5612 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
5615 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
5617 Handle string aliases for character tokens correctly.
5618 * src/symtab.c (symbol_user_token_number_set): If the token has an
5619 alias, check and set its alias's user token number instead of its own,
5620 which is set to indicate the alias. Previously, every occurrence of
5621 the character token in the grammar overwrote that alias indicator with
5623 * tests/input.at (String aliases for character tokens): New test.
5625 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
5627 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
5629 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
5631 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
5632 to prevent failures when building on older platforms.
5633 Check for autopoint failure.
5634 Set XGETTEXT_OPTIONS to values that check for C format strings,
5635 so that translators are warned about them (this also helps
5636 prevent core dumps).
5638 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
5639 function, since it simplifies our code a bit.
5641 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
5642 rather than -W, so we don't get bogus warnings about sign comparisons.
5643 Add -Wpointer-arith, since that warning is useful (it reports code
5644 that does not conform to C89 and that some compilers reject).
5645 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
5646 since it's no longer needed.
5648 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
5650 Clean up scanners a bit.
5651 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
5652 definitions so gcc won't warn when obstack_for_string is unused.
5653 * src/scan-code.l: config.h and system.h are already #include'd by
5654 scan-code-c.c, so get rid of them here.
5655 * src/scan-gram.l: Likewise.
5656 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
5657 definitions rather than duplicating the rest of it.
5658 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
5660 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
5662 Suppress signed/unsigned comparison warnings for yycheck.
5663 * data/c.m4 (b4_safest_int_type): New macro.
5664 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
5665 a signed int type, cast it to b4_safest_int_type first.
5666 * data/yacc.c: Likewise.
5667 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
5670 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
5672 * doc/bison.texinfo: Fix some typos.
5674 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
5676 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
5677 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
5679 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
5680 the latest gnulib does this a different way.
5681 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
5682 translation was patched, so stop omitting it.
5684 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5686 Enable declaration of default %printer/%destructor. Make the parser
5687 use these for all user-declared grammar symbols for which the user does
5688 not declare a specific %printer/%destructor. Thus, the parser uses it
5689 for token 0 if the user declares it but not if Bison generates it as
5690 $end. Discussed starting at
5691 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
5692 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
5694 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
5695 * NEWS (2.3+): Mention.
5696 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
5697 declare a %destructor for a mid-rule's semantic value. It's just
5698 impossible to declare one specific to it.
5699 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
5700 code. Describe default %destructor form.
5701 * src/parse-gram.y (grammar_declaration): Parse default
5702 %printer/%destructor declarations.
5703 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
5704 and symbol_destructor_location_get rather than accessing the destructor
5705 and destructor_location members of struct symbol.
5706 (symbol_printers_output): Likewise but for %printer's.
5707 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
5709 * src/symtab.c (default_destructor, default_destructor_location,
5710 default_printer, default_printer_location): New static global
5711 variables to record the default %destructor and %printer.
5712 (symbol_destructor_get, symbol_destructor_location_get,
5713 symbol_printer_get, symbol_printer_location_get): New functions to
5714 compute the appropriate %destructor and %printer for a symbol.
5715 (default_destructor_set, default_printer_set): New functions to set the
5716 default %destructor and %printer.
5717 * src/symtab.h: Prototype all those new functions.
5718 * tests/actions.at (Default %printer and %destructor): New test to
5719 check that the right %printer and %destructor are called, that they're
5720 not called for $end, and that $$ and @$ work correctly.
5721 (Default %printer and %destructor for user-declared end token): New
5722 test to check that the default %printer and %destructor are called for
5723 a user-declared end token.
5724 * tests/input.at (Default %printer and %destructor redeclared, Unused
5725 values with default %destructor): New tests to check related grammar
5726 warnings and errors.
5728 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5730 Clean up handling of %destructor for the end token (token 0).
5731 Discussed starting at
5732 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
5734 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
5736 Make the skeletons consistent in how they pop the end token and invoke
5738 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
5739 state, which has token number 0, since this would invoke the
5740 %destructor for the end token.
5741 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
5742 until after shifting the end token, or else it won't be popped.
5743 * data/yacc.c (yyparse): Likewise.
5745 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
5746 it's the end token. Upon termination, destroy an unshifted lookahead
5747 even when it's the end token.
5748 * data/lalr1.cc (yy::parser::parse): Likewise.
5749 * data/yacc.c (yyparse): Likewise.
5751 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
5752 value warnings for the end token when the user gives the end token a
5755 * tests/actions.at (Printers and Destructors): Test all the above.
5757 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5759 Update to latest gnulib and gettext versions.
5760 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
5762 (gnulib_files): Add m4/warning.m4. Don't worry about files
5763 overwritten by autopoint.
5764 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
5765 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
5767 Don't use autoreconf; instead, invoke autopoint etc. by hand,
5768 so that we can remove the intl files at a better time.
5769 (intl_files_to_remove): Remove aclocal.m4, since it gets
5770 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
5771 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
5772 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
5773 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
5774 Remove datarootdir hack; no longer needed.
5775 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
5776 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
5777 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
5779 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
5780 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
5782 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5784 * bootstrap: Adjust to today's change to gnulib-tool by invoking
5785 it with --assume-autoconf='latest-stable'.
5787 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
5789 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
5790 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
5792 * src/muscle_tab.h (muscle_grow): Replace the header comments with
5793 those from muscle_tab.c since the old ones are misleading.
5795 2006-07-13 Akim Demaille <akim@epita.fr>
5797 Support %define "KEY" {VALUE}.
5798 * src/scan-code.h, src/scan-code.l (translate_action)
5799 (translate_rule_action, translate_symbol_action, translate_code):
5800 Return char *, not const char *.
5801 * src/parse-gram.y (declaration): Rename as...
5802 (prologue_declaration): this.
5803 (string_content): Remove this nonterminal, use STRING.
5804 (braceless, content, content.opt): New nonterminal.
5806 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
5808 * src/scan-gram.l (getargs.h): Don't include it.
5810 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
5812 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
5813 rather than a for-loop that declares a local bool variable. This
5814 should work around a compatibility problem with a Cray x1e C++
5815 compiler reported by Hung Nguyen in
5816 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
5817 The for-loop was introduced in the 2004-11-17 change but I don't
5818 know why it was needed.
5820 2006-07-12 Akim Demaille <akim@epita.fr>
5822 * data/c.m4: Comment changes.
5824 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
5826 * src/complain.c (error_message, ERROR_MESSAGE): New.
5828 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
5829 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
5831 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5833 * NEWS: Instead of %union, you can define and use your own union type
5834 YYSTYPE if your grammar contains at least one <type> tag.
5835 Your YYSTYPE need not be a macro; it can be a typedef.
5836 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
5837 (Union Decl, Decl Summary): Document this.
5838 * data/glr.c (YYSTYPE): Implement this.
5839 * data/glr.cc (YYSTYPE): Likewise.
5840 * data/lalr1.cc (YYSTYPE): Likewise.
5841 * data/yacc.c (YYSTYPE): Likewise.
5842 * src/output.c (prepare): Output tag_seen_flag.
5843 * src/parse-gram.y (declaration, grammar_declaration):
5844 Use 'union_seen' rather than 'typed' to determine whether
5845 %union has been seen, since grammars can now be typed without
5847 (symbol_declaration, type.opt, symbol_def):
5848 Keep track of whether a tag has been seen.
5849 * src/reader.c (union_seen, tag_seen): New vars.
5851 * src/reader.h (union_seen, tag_seen, typed): Likewise.
5852 * src/scan-code.l (untyped_var_seen): New variable.
5853 (handle_action_dollar): Adjust to above changes.
5854 (handle_action_dollar, handle_action_at):
5855 Improve overflow checking for outlandish numbers.
5856 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
5857 avoid new diagnostics generated by above changes.
5858 * tests/regression.at (YYSTYPE typedef): Add test to check
5859 for type tags without %union.
5861 * src/symlist.c (symbol_list_length): Return int, not unsigned
5862 int, since callers expect int. This may need to get revisited
5863 once we have proper integer overflow checking.
5865 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
5866 object is now static.
5868 * src/getargs.c (flags_argmatch): Return void, not int,
5869 to pacify ./configure --enable-gcc-warnings.
5871 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
5872 since last_string is already defined to FLEX_PREFIX (last_string).
5874 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5876 Implement --warnings/-W.
5877 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
5879 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
5881 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
5882 (warnings_args, warnings_types): New.
5883 (getargs, short_options, long_options): Accept -W/--warnings.
5884 Sort the options by alphabetical order, upper case letter right
5885 before its lower case.
5887 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5889 Change %merge result type clash warnings to errors. Discussed at
5890 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
5891 * src/reader.c (record_merge_function_type): Use complain_at.
5892 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5893 declared later): Update test case results.
5895 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5897 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
5898 to be in alphabetical order.
5899 (trace_args): Spelling fixes.
5901 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5903 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
5904 so they don't collide with user-defined macros.
5905 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
5906 this was never guaranteed, and now that we're using gnulib stdint,
5907 which defines int_fast16_t to long int, the problem is exposed.
5909 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
5911 * data/c.m4 (b4_basename): Simplify a bit, since we don't
5912 need the full POSIX semantics (and weren't implementing them
5915 Adjust to Autoconf 2.60 and today's gnulib.
5916 * bootstrap (gnulib_modules): Add stdint.
5917 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
5918 no longer copies it.
5919 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
5920 since stdint needs the former and wcwidth (which is now required
5921 by mbswidth) needs the latter.
5922 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
5923 work around a compatibility glitch between gettext 0.14.6 and
5925 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
5926 Do not check for uintptr_t, since new stdint module does the right
5928 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
5929 Add stdint.h, stdint_.h, wcwidth.h.
5930 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
5931 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
5932 stdint.m4, wchar_t.m4, wcwidth.m4.
5933 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
5934 usual order for ../lib/*.h files.
5935 (file_name_split): Use last_component, not base_name, to adjust
5937 * src/parse-gram.h: Include <strverscmp.h> in the usual order
5938 for ../lib/*.h files.
5939 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
5940 Define unconditionally, since we now assume the stdint module.
5941 * src/scan-skel.l: Include <dirname.h>.
5942 (BASE_QPUTS): Use last_component, not base_name.
5943 * src/system.h: Include <unlocked-io.h> in the usual order
5944 for ../lib/*.h files. Include <stdint.h> unconditionally,
5945 since we now use the stdint module.
5946 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
5947 HAVE_UINTPTR_T, since we now use the stdint module.
5948 (base_name): Remove decl, since files now include <dirname.h>
5951 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5953 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
5955 * data/yacc.c, data/glr.c, data/location.cc: Use them.
5956 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
5958 * tests/calc.at: Adjust.
5960 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5962 * data/c.m4 (b4_basename): New.
5963 (b4_syncline): Also output the location of its invocation (from
5965 (b4_user_action, b4_define_user_action, b4_user_actions)
5966 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
5967 (b4_user_stype): New.
5968 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
5970 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5972 In the grammar file, the first column is 1 not 0 on the first line as
5973 on every other line.
5974 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
5975 * tests/input.at (Torturing the Scanner): Update output.
5977 * src/scan-gram.l (scanner_cursor): Declare it static.
5979 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5981 In warnings, say "previous declaration" rather than "first
5983 * src/symtab.c (redeclaration): Do that here.
5984 * src/reader.c (record_merge_function_type): In the case of a result
5985 type clash, report the previous declaration rather than the very first
5986 one in the grammar file.
5987 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5988 declared later): Add a third declaration to check this behavior.
5989 * tests/input.at (Incompatible Aliases): Update output.
5991 2006-06-27 Akim Demaille <akim@epita.fr>
5993 * doc/Doxyfile.in: New.
5994 * doc/Makefile.am: Use it.
5995 * src/lalr.h, src/symtab.h: Initial doxygenation.
5997 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5999 Don't miss %merge result type warnings just because the LHS types are
6000 declared after the %merge. This continues the effort of the previous
6002 * src/reader.c (get_merge_function): Don't set the merger type yet.
6003 (record_merge_function_type): New function for setting the merger type
6004 and checking for clashes.
6005 (grammar_current_rule_merge_set): Set the location of the %merge for
6007 (packgram): Invoke record_merge_function_type for each rule now that
6008 all symbol type declarations have been parsed.
6009 * src/reader.h (merger_list.type_declaration_location): New member
6010 storing the location of the first %merge from which the type for this
6011 merging function was derived.
6012 * src/symlist.h (symbol_list.merger_declaration_location): New member
6013 storing the location of a rule's %merge, if any.
6014 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6015 declared later): New test to catch the error fixed by the above patch.
6017 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6019 Get action warnings (grammar_rule_check) right even when symbol
6020 declarations appear after the rules. Discussed at
6021 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
6023 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
6024 Don't mistake the type of $$ in a midrule to be that of its parent
6026 * src/reader.c (grammar_current_rule_end): Don't invoke
6027 grammar_rule_check yet since not all symbol declarations may have been
6029 (grammar_midrule_action): Likewise.
6030 Don't record whether the midrule's $$ has been used yet since actions
6031 haven't been translated yet.
6032 Record the midrule's parent rule and its RHS index within the parent
6034 (grammar_current_rule_action_append): Don't translate the action yet
6035 since not all symbol declarations may have been parsed yet and, thus,
6036 warnings about types for $$, $n, @$, and @n can't be reported yet.
6037 (packgram): Translate the action and invoke grammar_rule_check now that
6038 all symbol declarations have been parsed.
6039 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6040 after parsing the entire grammar file, the symbol list here in the case
6041 of a midrule is actually the midrule's empty RHS, so reference its
6042 parent rule's RHS where necessary.
6043 On the other hand, now that you can already know it's a midrule, you
6044 aren't forced to think $$ has the same type as its parent rule's $$.
6045 (handle_action_at): In the case of a midrule, reference the parent rule
6047 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6049 (symbol_list_length): Now that this is invoked after all rules have
6050 been parsed, a NULL symbol (rather than a NULL symbol list node)
6051 terminates a rule. symbol_list_print already does this correctly.
6052 * src/symlist.h (symbol_list.midrule_parent_rule,
6053 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6054 remember their relationships with their parents.
6055 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6056 fixed by the above patch.
6057 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6059 (Unused values): ... this old test case and...
6060 (Unused values before symbol declarations): ... this new test case.
6061 This one is the same as `Unused values' except that all symbol
6062 declarations appear after the rules in order to catch the rest of the
6063 errors fixed by the above patch.
6065 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6068 * src/reader.c (current_rule): Declare it static since it's no longer
6069 used outside this file.
6070 (grammar_current_rule_action_append): Remove redundant arguments from
6071 translate_rule_action invocation.
6072 * src/reader.h (current_rule): Remove this unused extern.
6073 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
6074 * src/scan-code.l (translate_rule_action): Likewise.
6076 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
6078 Clean up yesterday's patch.
6079 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
6081 * src/reader.c (grammar_current_rule_action_append): ... here for
6082 consistency with grammar_current_rule_symbol_append.
6083 * tests/regression.at (Braced code in declaration in rules section):
6084 Make yyerror and yylex static as usual.
6086 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
6088 Fix bug that mistakes braced code in a declaration in the rules section
6089 to be a rule action. Mentioned at
6090 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
6091 * src/scan-gram.l: Move midrule action detection from the start of the
6092 scanning of any braced code to...
6093 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
6094 action. For readability, use $2 and @2 rather than the equivalent
6096 * tests/regression.at (Braced code in declaration in rules section):
6097 New test to catch the error fixed by the above patch.
6099 Work on code readability some.
6100 * src/scan-code.l (current_rule): Get rid of this misleading and
6101 redundant declaration: it's actually extern'ed in reader.h.
6102 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
6103 translate_action): Add a rule argument and use it instead of the global
6105 (translate_rule_action): This already receives current_rule through an
6106 argument, so pass it on to translate_action instead of assigning
6107 current_rule to current_rule.
6108 (translate_symbol_action, translate_code): Pass rule = NULL to
6111 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
6113 Rename %before-definitions to %start-header and %after-definitions to
6114 %end-header. Don't use these declarations to separate pre-prologue
6115 blocks from post-prologue blocks. Add new order-independent
6116 declarations %before-header and %after-header as alternatives to the
6117 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
6118 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
6119 * NEWS (2.3+): Update for these changes.
6120 * data/glr.c (b4_before_definitions): Update to...
6121 (b4_start_header): ... this.
6122 (b4_after_definitions): Update to...
6123 (b4_end_header): ... this.
6124 * data/glr.cc: Likewise.
6125 * data/lalr1.cc: Likewise.
6126 * data/yacc.c: Likewise.
6127 * doc/bison.texinfo (The prologue): Update names, and replace remaining
6128 prologue blocks with %*-header declarations.
6129 (Calc++ Parser): Likewise.
6130 (Decl Summary): Update names.
6131 (Table of Symbols): Update description.
6132 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
6133 (PERCENT_END_HEADER): ... this.
6134 (PERCENT_BEFORE_DEFINITIONS): Update to...
6135 (PERCENT_START_HEADER): ... this.
6136 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6137 (declaration): Update token names and m4 macro names.
6138 When parsing %end-header and %start-header, invoke translate_code
6139 before muscle_code_grow, and no longer set global booleans to remember
6140 whether these declarations have been seen.
6141 Parse new %after-header and %before-header.
6142 * src/reader.c (before_definitions, after_definitions): Remove.
6143 (prologue_augment): Accept a new bool argument to specify whether to
6144 augment the pre-prologue or post-prologue.
6145 * src/reader.h (before_definitions, after_definitions): Remove these
6147 (prologue_augment): Add new bool argument.
6148 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
6149 (PERCENT_END_HEADER): ... this.
6150 (PERCENT_BEFORE_DEFINITIONS): Update to...
6151 (PERCENT_START_HEADER): ... this.
6152 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6153 * tests/actions.at (Printers and Destructors): Update names.
6155 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
6157 Add comparison operators for C++ location classes. Discussed at
6158 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
6159 * data/c++.m4 (b4_define_location_comparison): New boolean %define
6160 declaration indicating whether filename_type has an operator==. If
6161 filename_type is `std::string', it defaults to `1', `0' otherwise.
6162 * data/location.cc: Iff b4_define_location_comparison is `1', add
6163 operator== and operator!= for class position and for class location.
6166 * src/scan-action.l: Remove unused file.
6167 * src/symtab.c (symbol_printer_set): Use printer_location not
6168 destructor_location.
6169 * src/symtab.h (struct symbol): Replace incorrect source comment for
6171 * tests/input.at (Incompatible Aliases): Update output with correct
6174 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
6176 Don't put the pre-prologue in the header file. For the yacc.c code
6177 file and the glr.c header and code files, move the pre-prologue before
6178 the token definitions. Add new %before-definitions and
6179 %after-definitions to declare code that will go in both the header file
6180 and code file. Discussed at
6181 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
6182 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
6184 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
6185 * NEWS (2.3+): Describe these changes.
6186 * data/glr.c (b4_pre_prologue): Move from within to before...
6187 (b4_shared_declarations): ... this.
6188 Add new b4_before_definitions before b4_token_enums.
6189 Add new b4_after_definitions at the end.
6190 * data/glr.cc (b4_pre_prologue): Replace with...
6191 (b4_before_definitions): ... this in the header file.
6192 (b4_after_definitions): New near the end of the header file.
6193 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
6194 code file right before including the header file.
6195 (b4_before_definitions): New in the previous position of
6196 b4_pre_prologue in the header file.
6197 (b4_after_definitions): New near the end of the header file.
6198 * data/yacc.c: Clean up some m4 quoting especially in the header file.
6199 (b4_token_enums_defines): In the code file, move to right before
6200 YYSTYPE for consistency with the header file.
6201 (b4_before_definitions): New right before b4_token_enums_defines in
6202 both the header and code file.
6203 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
6204 header and code file.
6205 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
6206 of prologues for %union dependencies.
6207 (Decl Summary): In %defines description, mention the effect of
6208 %before-definitions and %after-definitions on the header file.
6209 (Calc++ Parser): Forward declare driver in a %before-definitions rather
6210 than in the pre-prologue so that make check succeeds.
6211 (Table of Symbols): Add entries for %before-definitions and
6213 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
6214 %before-definitions.
6215 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
6216 (declaration): Parse those declarations and append to
6217 b4_before_definitions and b4_after_definitions, respectively.
6218 * src/reader.c (before_definitions, after_definitions): New bools to
6219 track whether those declarations have been seen.
6220 (prologue_augment): Add to the post-prologue if %union,
6221 %before-definitions, or %after-definitions has been seen.
6222 * src/reader.h (before_definitions, after_definitions): New extern's.
6223 * src/scan-gram.l: Scan the new declarations.
6224 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
6225 prologue block in a %before-definitions or a %after-definitions based
6226 on whether the %union is declared.
6227 * tests/regression.at (Early token definitions with --yacc, Early token
6228 definitions without --yacc): Move tests for token definitions into the
6229 post-prologue since token names are no longer defined in the
6232 2006-06-20 Akim Demaille <akim@epita.fr>
6234 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
6235 (symbol_get): Use it.
6236 * src/parse-gram.y: Use it.
6238 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
6240 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
6241 build succeeds when configured with --enable-gcc-warnings.
6243 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6245 * src/parse-gram.y (char_name): New function.
6246 (CHAR, STRING, string_content): For %printer, properly escape.
6247 (ID): Prefer fputs to fprintf.
6248 (id): Reindent to be consistent with other rules.
6249 Properly quote char.
6251 The Translation Project changed its way of publishing translations
6252 to maintainers. I haven't received any responses to my request
6253 for supporting the old way, or for documenting the new way. I
6254 have modified 'bootstrap' to use screen scraping
6255 (in this case, HTML scraping). This is unreliable and inelegant,
6256 but I don't see any better way. Yuck.
6257 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6258 (get_translations): New function, which uses HTML scraping to
6259 deduce locations of latest translations.
6260 Use this function to grab both bison and bison-runtime .po files.
6261 Don't bother priming the pump for the runtime-po domain any more,
6262 as it's now translated better than bison is.
6264 2006-06-19 Akim Demaille <akim@epita.fr>
6266 * src/scan-gram.l: No longer "parse" things after `%union' until
6267 `{'. Rather, return a single "%union" token.
6268 No longer make symbols: return strings, and leave the conversion
6269 to symbols to the parser.
6270 (SC_PRE_CODE, token_type): Remove.
6271 * src/parse-gram.y (%union): New field `character'.
6274 (ID, ID_COLON): Now that the scanner no longer makes them
6275 identifiers, adjust all uses to invoke symbol_get.
6276 (id_colon): New, wraps the conversion from string to symbol.
6277 (%union): Accept a possible union_name.
6278 (symbol): Now can be a char.
6279 * data/c.m4 (b4_union_name): Leave a default value.
6280 * data/glr.c, data/yacc.c: Use it.
6282 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6284 For associating token numbers with token names for "yacc.c", don't use
6285 #define statements unless `--yacc' is specified; always use enum
6286 yytokentype. Most important discussions start at:
6287 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6288 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6290 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6291 * NEWS (2.3+): Mention.
6292 * data/c.m4 (b4_yacc_if): New.
6293 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6295 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6296 on token name definitions.
6297 * src/getargs.c (usage): Capitalize `Yacc' in English.
6298 * src/output.c (prepare): Define b4_yacc_flag.
6299 * tests/regression.at (Early token definitions): Test that tokens names
6300 are defined before the pre-prologue not just before the post-prologue.
6301 Remove this test case and copy to...
6302 (Early token definitions with --yacc): ... this to test #define's.
6303 (Early token definitions without --yacc): ... and this to test enums.
6305 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6307 * NEWS: Reword the post-2.3 change to not be so optimistic about
6308 removing the old "look-ahead" spelling.
6309 Update previous look-ahead/lookahead change reports.
6310 * REFERENCES: look-ahead -> lookahead (since that's
6311 what he actually wrote).
6312 * doc/refcard.tex: look ahead -> lookahead,
6313 look-ahead -> lookahead
6315 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6317 For consistency, use `lookahead' instead of `look-ahead' or
6318 `look_ahead'. Discussed starting at
6319 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>

6388 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
6390 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
6392 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
6394 * TODO: Add request from Nelson H. F. Beebe to be able to install
6395 Bison without installing the yacc script.
6397 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6399 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
6400 and yytext if they're already #define'd.
6401 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
6402 * src/scan-code-c.c: ... here.
6403 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
6406 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6408 Get Bison to build again when configured with --enable-gcc-warnings.
6409 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
6411 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
6412 loc argument as it shadows a global.
6413 * src/scan-gram.l: Remove stray comma that prevents boundary_set
6416 * src/.cvsignore: Add scan-code.c.
6418 2006-06-07 Akim Demaille <akim@epita.fr>
6420 * src/scan-gram.l: Move the "add a trailing ; to actions" code
6422 * src/scan-code.l: here.
6423 * tests/input.at (Torturing the Scanner): Fix another location
6426 2006-06-07 Akim Demaille <akim@epita.fr>
6428 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
6430 2006-06-06 Akim Demaille <akim@epita.fr>
6432 Extract the parsing of user actions from the grammar scanner.
6433 As a consequence, the relation between the grammar scanner and
6434 parser is much simpler. We can also split "composite tokens" back
6436 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
6437 * src/scan-gram.l (add_column_width, adjust_location): Move to and
6439 * src/location.h, src/location.c (add_column_width)
6440 (location_compute): these.
6441 Fix the column count: the initial column is 0.
6442 (location_print): Be robust to ending column being 0.
6443 * src/location.h (boundary_set): New.
6444 * src/main.c: Adjust to scanner_free being renamed as
6446 * src/output.c: Include scan-code.h.
6447 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
6449 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
6450 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
6451 which is now, again, a separate token.
6452 Adjust all dependencies.
6453 Whereever actions with $ and @ are used, use translate_code.
6454 (action): Remove this nonterminal which is now useless.
6455 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
6456 (grammar_current_rule_action_append): Use translate_code.
6457 (packgram): Bound check ruleno, itemno, and rule_length.
6458 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
6459 (last_string, last_braced_code_loc, max_left_semantic_context)
6460 (scanner_initialize, scanner_free, scanner_last_string_free)
6461 (gram_out, gram_lineno, YY_DECL_): Move to...
6462 * src/scan-gram.h: this new file.
6463 (YY_DECL): Rename as...
6465 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
6466 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6467 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6468 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6469 Move these declarations, and...
6470 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
6472 * src/flex-scanner.h: this new file.
6473 * src/scan-gram.l (rule_length, rule_length_overflow)
6474 (increment_rule_length): Remove.
6475 (last_braced_code_loc): Rename as...
6476 (gram_last_braced_code_loc): this.
6477 Adjust to the changes of the parser.
6478 Move all the handling of $ and @ into...
6479 * src/scan-code.l: here.
6480 * src/scan-gram.l (handle_dollar, handle_at): Remove.
6481 (handle_action_dollar, handle_action_at): Move to...
6482 * src/scan-code.l: here.

6493 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6495 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6496 Use Akim's wording from
6497 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
6499 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6501 Between Bison releases, manually append `+' to the previous Bison
6502 release number, and use that as a signal to automatically print the
6503 ChangeLog's CVS Id keyword from --version. Discussed starting at
6504 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
6505 * ChangeLog: Add Id header.
6506 * configure.ac (AC_INIT): Append `+' to `2.3'.
6507 * src/.cvsignore: Add revision.c.
6508 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
6509 (BUILT_SOURCES): Add revision.c.
6510 (revision.c): New target rule. This file defines a new global variable
6511 named revision. It initializes it with either the Id from ChangeLog
6512 or, if VERSION doesn't contain `+', with the empty string.
6513 * src/getargs.c (version): Print the value of revision.
6514 * src/revision.h: Extern revision.
6516 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
6518 * NEWS: Version 2.3.
6519 * configure.ac (AC_INIT): Likewise.
6521 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
6523 * data/glr.c (YYRECOVERING): Define to be a function-like macro
6524 with no arguments, not as an object-like macro. This is for
6525 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
6526 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
6527 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
6530 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
6532 * src/getargs.c (usage): Back out yesterday's modification of the
6533 --help output so that we don't have to wait for translation before
6536 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
6538 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
6539 Problem reported by Akim Demaille.
6541 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6543 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6545 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6547 * data/yacc.c (yy_reduce_print): Omit trailing white space in
6548 generated source code. Problem reported by Frans Englich in
6549 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
6551 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
6553 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
6554 shell, not within 'make', so that 'make' by an ordinary builder
6555 (using GNU make) does not worry about configuring gzip. This also
6556 works around a bug reported independently by Keith Thompson and by
6557 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
6558 stderr rather than stdout, messing up the build logs.
6560 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6562 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
6563 to make sure that YYID will never be unused. This fixes a 'make
6564 maintainer-check' failure caused by the recent changes to the 'Trivial
6565 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
6567 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
6569 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6571 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
6572 state before an empty RHS is always resolved here. Only the location
6573 of that state is guaranteed to be resolved, and that's enough. This
6574 fixes the remaining bug reported by Derek M. Jones in
6575 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6576 * tests/glr-regression.at (Uninitialized location when reporting
6577 ambiguity): Test the above case.
6578 Also, the embedded comments in this test case claim it checks the case
6579 of an empty RHS that has inherited the initial location. However, the
6580 corresponding LHS was already resolved, so yyresolveLocations didn't
6581 actually have reason to modify it. Fix this by forcing
6582 nondeterministic operation at the beginning of the parse.
6584 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6586 * data/c.m4 (b4_yy_symbol_print_generate):
6587 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
6588 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
6589 of the bugs reported today by Derek M Jones in
6590 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6591 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
6592 defined to be a type name without parens or brackets.
6593 (Location Type): Similarly for YYLTYPE.
6594 * tests/regression.at (Trivial grammars): Put in a test for this
6595 bug that will be caught by 'make maintainer-check' (though not,
6596 alas, by 'make check' unless your compiler is picky).
6598 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>

6603 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
6605 * data/glr.c (yyreportTree): Make room in yystates for the state
6606 preceding the RHS. This fixes the segmentation fault reported by Derek
6608 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
6609 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
6610 to the user. Reported for yyreportTree by Derek M. Jones later in the

6614 Fix typo in Steve Murphy's name.
6616 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6618 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
6619 checking against YYLAST that caused the parser to miss a potential
6620 alternative in its diagnostic.
6621 Problem reported by Maria Jose Moron Fernandez in
6622 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
6623 * data/lalr1.cc (yysyntax_error_): Likewise.
6624 * data/yacc.c (yysyntax_error): Likewise.
6625 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
6626 tokens, in case we run into an older C compiler.
6627 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
6628 Use them to check for the off-by-one error fixed above.
6630 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
6631 YYSIZE_T, not size_t.
6632 * tests/regression.at (Trivial grammars): New test, to catch
6633 the error fixed by the above patch.
6635 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6637 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
6639 Reported by Steve Murphy.
6641 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6643 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
6644 * data/glr.cc: b4_location_flag is now b4_locations_flag.
6646 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6648 Implement --trace=m4.
6649 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
6650 * src/output.c (output_skeleton): When set, pass -dV to m4.
6652 Factor the handling of flags in m4.
6653 * src/output.c (prepare): Rename the muscle names debug, defines,
6654 error_verbose to debug_flag, defines_flag, error_verbose_flag.
6655 * data/c.m4: Adjust.
6656 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
6657 Use b4_define_flag_if to define other b4_FLAG_if macros.
6658 (b4_location_if): As a consequence, rename as...
6659 (b4_locations_if): this, for consistency.
6660 Adjust all the skeletons.
6662 2006-05-14 Akim Demaille <akim@lrde.epita.fr>

6671 Adjust dependencies.
6673 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6675 * data/c.m4 (b4_copyright): Put the special exception for Bison
6676 skeletons here, so we don't have to put it in each skeleton. All
6677 uses changed. Suggested by Akim Demaille. Also, wrap the
6678 copyright notice, in case it is longer than 80 columns. Replace
6679 comma by newline after title.
6681 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6683 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
6684 incompatibility, not a bug. Mention that it wasn't fixed as of
6687 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6689 * examples/extexi: Enforce the precedence of concatenation over
6691 Reported by Tommy Nordgren.
6693 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6695 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
6696 with the member "token".
6697 Reported by Martin Nylin.
6699 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
6701 * data/glr.c: Switch to Bison 2.2 special-exception language in
6702 the copyright notice. Use more-regular format for titles and

6712 * data/glr.cc: Remove dead code.
6714 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6716 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
6717 that variable and the line breaks the bootstrap. Problem reported
6718 by Juan M. Guerrero.
6720 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

6738 Problem reported by Bob Rossi.
6740 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
6742 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
6743 and didn't really work.
6744 For the index, use @ifnotinfo, not @iftex.
6745 Minor cleanups of spacing and terminology.
6747 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6749 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
6750 of AT_NAME_PREFIX when %name-prefix is not used.
6752 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6754 Apply --prefix to C++ skeletons too: they change the namespace.
6755 The test suite already exercize these cases.
6756 * data/c++.m4 (b4_namespace): New.
6757 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
6758 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
6759 * data/yacc.c, data/glr.c: Remove a useless `[]'.
6760 * doc/bison.texinfo: Document it.
6761 (Option Cross Key): Use @multitable in all formats. It looks
6762 nicer, even in TeX outputs.
6763 (Rules): Use the same code whatever the output type is.
6764 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
6765 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
6766 * tests/calc.at: Use it, instead of hard coding `yy'.

6783 * doc/bison.texinfo (Calc++ Scanner): Use it.
6785 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
6787 Fix two nits reported by twlevo, plus one more that I discovered.
6789 * src/assoc.h (assoc_to_string): Give a name to the arg, as
6790 this is the usual Bison style.
6791 * src/location.h (location_print): Likewise.
6793 * src/reader.h (token_name): Likewise.
6795 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
6797 Fix some nits reported by twlevo.
6798 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
6799 and "POSIX". Use more-modern syntax for URLs. Mention C++
6800 and ask for Java. Don't hardwire OS version numbers. Add
6802 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
6803 * src/conflicts.c (solved_conflicts_obstack): Now static.
6805 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
6807 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
6808 page. Say "you can use it" not "you may use it" as on the web page;
6809 we're describing capabilities not granting permission.
6811 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
6813 * data/glr.c (yyresolveLocations): Rename local variables to avoid
6814 shadowing warnings. Use usual patter for iterating through RHS.
6815 * tests/glr-regression.at
6816 (Uninitialized location when reporting ambiguity):
6817 Modify yylex so that it uses its argument, rather than trying
6818 to rely on ARGSUSED (which doesn't work for gcc with warnings).
6819 const char -> char const.
6821 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
6822 Don't use tabs inside commands; it messes up 'ps'.
6823 Problem reported by twlevo.
6825 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
6827 * tests/glr-regression.at (Uninitialized location when reporting
6828 ambiguity): New test case.
6829 * data/glr.c (yyresolveLocations): New function, which uses
6831 (yyresolveValue): Invoke yyresolveLocations before reporting an
6833 * doc/bison.texinfo (Default Action for Locations): Note
6834 YYLLOC_DEFAULT's usage for ambiguity locations.
6835 (GLR Semantic Actions): Cross-reference those notes.
6837 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
6839 * tests/glr-regression.at (Leaked semantic values when reporting
6840 ambiguity): Remove unnecessary union and type declarations.
6841 (Leaked lookahead after nondeterministic parse syntax error): New test
6843 * data/glr.c (yyparse): Check for zero stacks remaining before
6844 attempting to shift the lookahead so that you don't lose it.
6846 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6848 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
6849 * tests/glr-regression.at (Leaked semantic values when reporting
6850 ambiguity): New test case.
6851 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
6852 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
6853 now unnecessary yystackp parameter.
6854 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
6855 destructors can be called.
6857 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
6858 in existing testcases.
6860 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6862 Don't leak semantic values for parent RHS when a user action cuts the
6863 parser, and clean up related code a bit.
6864 * tests/glr-regression.at (Leaked merged semantic value if user action
6865 cuts parse): Rename to...
6866 (Leaked semantic values if user action cuts parse): ... this. Add check
6867 for leaked parent RHS values.
6868 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
6869 between an unresolved state (non-empty chain of semantic options) and
6870 an incomplete one (signaled by an empty chain).
6871 (yyresolveStates): Document the interface. Move all manipulation of a
6872 successfully or unsuccessfully resolved yyGLRState to...
6873 (yyresolveValue): ... here so that yyresolveValue always leaves a
6874 yyGLRState with consistent data and thus is easier to understand.
6875 Remove the yyvalp and yylocp parameters since they are always just
6876 taken from the yys parameter. When reporting a discarded merged value
6877 in debugging output, note that it is incompletely merged. Document the
6879 (yyresolveAction): If resolving any of the RHS states fails, destroy
6880 them all rather than leaking them. Thus, as long as user actions are
6881 written to clean up the RHS correctly, yyresolveAction always cleans up
6882 the RHS of a semantic option. Document the interface.
6884 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
6886 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
6887 led to a segmentation fault in GNU Pascal. Problem reported
6890 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
6892 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
6893 mid-rule action inside a nonterminal symbol in order to declare a
6894 destructor for its semantic value.

6901 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||

6903 declarations of malloc and free, to avoid problems with
6904 incompatible declarations (using 'throw') C++'s stdlib.h. This
6905 should fix Debian bug 340012

6948 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
6949 nodist_PROGRAMS, since we don't need to actually compile the
6950 example if we're just doing a plain 'make'. This avoids bothering
6951 the installer unnecessarily about problems due to weird C++

6960 not portable, according to Posix and the C standard, and it does
6961 not work with Sun C 5.7, where previous #line directives affect

6985 "warning: sorry: semantics of inline function static data `const

6992 random system header somewhere that includes the equivalent of

7001 During deterministic GLR operation, user actions should be able to
7002 influence the parse by changing yychar. To make this easier to fix and
7003 to make glr.c easier to evolve in general, don't maintain yytoken in
7004 parallel with yychar; just compute yytoken when needed.

7011 yychar rather than *yytokenp to determine the current lookahead.
7012 Compute yytoken locally when needed.

7031 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7032 got from <http://bro-ids.org/download.html>. The bug is that
7033 when two actions appeared in succession, the second one was
7034 scanned before the first one was added to the grammar rule
7035 as a midrule action. Bison then output the incorrect warning
7036 "parse.y:905.17-906.36: warning: unused value: $3".
7037 * src/parse-gram.y (BRACED_CODE, action): These are no longer
7038 associated with a value.
7039 (rhs): Don't invoke grammar_current_rule_action_append.

7041 * src/reader.c (grammar_midrule_action): Now extern.
7042 (grammar_current_rule_action_append): Don't invoke
7043 grammar_midrule_action; that is now the scanner's job.

7057 All used changed. Check whether the symbol has a destructor,
7058 not whether it is typed.

7078 (short): #undef, to work around a bug in Pike 7.0.
7079 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
7080 (union yyalloc.yyss): Use yytype_int16 rather than short.
7082 (yysigned_char): Remove.

7298 in the yychar entry.
7299 In the yychar entry, remove mention of the local yychar case (pure
7300 parser) since this is irrelevant information when writing semantic
7301 actions and since it's already discussed in `Table of Symbols' where
7302 yychar is otherwise described as an external variable.
7303 In the yychar entry, don't call it the `current' look-ahead since it
7304 isn't when semantic actions are deferred.
7305 In the yychar and yyclearin entries, add note about deferred semantic
7307 Add yylloc and yylval entries discussing look-ahead usage.
7308 (Look-Ahead Tokens): When discussing yychar, don't call it the

7331 members to store the current lookahead to be used by the deferred
7333 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
7334 from which the RHS is taken. Set the lookahead members of the new
7335 yySemanticOption according to the lookahead status for stack yyk.

7337 yyaddDeferredAction.
7338 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

7349 (Incorrect lookahead during nondeterministic GLR): New test case.
7351 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

7363 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7365 * data/glr.c (yyresolveValue): When merging semantic options, if at
7366 least one user action succeeds but a later one cuts the parse, then
7367 destroy the semantic value before returning rather than leaking it.
7368 (yyresolveStates): If a user action cuts the parse and thus
7369 yyresolveValue fails, ignore the (unset) semantic value rather than
7370 corrupting the yyGLRState, and empty the semantic options list since
7371 the user actions should have called all necessary destructors.
7372 Simplify code with YYCHK.
7373 * tests/glr-regression.at (Corrupted semantic options if user action
7374 cuts parse): New test case.
7375 (Undesirable destructors if user action cuts parse): New test case.

7572 Undo 2005-12-01 tentative license wording change. The wording is
7573 still being reviewed by the lawyers, and we don't want to wait for
7574 them before publishing a test release. For now, revert to the

7598 for semantic values was leaked instead.
7600 2005-12-21 Joel E. Denny <address@hidden>
7602 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.

7622 destroy the RHS symbols of a rule.
7623 * data/yacc.c (yylen): Initialize to 0.

7641 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
7642 * djgpp/config.sed: Replace every occurence of the file name
7643 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

7673 sed out the final state number.
7675 Work around portability problem on Solaris 10: flex-generated
7676 files include <stdio.h> before <config.h>, which messes up
7677 because the latter defines __EXTENSIONS__. Address the problem
7678 by creating two new little files that include <config.h> first,
7679 then include the flex-generated files. Rewrite everyone else
7680 to include <config.h> first, as well.
7681 * lib/timevar.c: Always include "config.h".

7723 definition if 'lint' is defined.
7724 (YYID): New macro (or function, if lint).
7725 All uses of /*CONSTCOND*/0 replaced by YYID(0).
7726 * data/yacc.c: Likewise.
7727 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
7728 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
7729 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
7731 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
7732 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
7733 Use YYID(0) rather than 0, for lint.
7734 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

7755 * NEWS: Document the following change.
7756 * data/yacc.c: Say "parser skeleton" rather than "file", since
7757 it's no longer just a file.
7758 * data/glr.c: Grant a special exception for C GLR parsers, that
7759 reads like the already-existing exception for C LALR(1) parsers.

7761 * data/lalr1.cc: Likewise.
7762 * data/location.cc: Likewise.

8024 but some people prefer the printf style.
8025 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
8026 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

8047 unused-variable warnings.
8049 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

8053 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
8055 Use unlocked I/O for a minor performance improvement on hosts like
8056 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8057 is to use the gnlib unlocked-io module, and to prefer putc and
8058 puts to printf when either will work (since the latter doesn't
8059 come in an unlocked flavor).
8060 * bootstrap (gnulib_modules): Add unlocked-io.

8079 * src/system.h: Include unlocked-io.h rather than stdio.h.
8081 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

8131 to allow support for non-posix systems. This is a no-op function
8134 * src/output.c (output_skeleton): Use end_of_output_subpipe() to

8219 local variables whose names begin with 'yy'.
8220 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8221 Trivial changes from Joel E. Denny.
8223 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
8225 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
8226 don't use alloca any more.
8228 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
8229 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
8230 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

8241 This works a bit better with glibc, if user code has already included
8243 * doc/bison.texinfo (Bison Parser): Document that users can't
8244 arbitrarily use malloc and free for other purposes. Document
8245 that <alloca.h> and <malloc.h> might be included.

8260 (yysyntax_error): New function.
8261 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
8262 multiple syntax errors are reported, and alloca is being used.
8263 Instead, reallocate buffers twice as big each time, so that
8264 we waste at most half the allocated memory. Start with a small
8265 (128-byte) buffer that will suffice in most cases anyway.
8266 Use yysyntax_error to do most of the work.
8268 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8269 yynerrs is the number of errors reported, not the number of

8278 2005-09-19 Akim Demaille <akim@epita.fr>
8280 Remove the traits, failed experiment.
8281 It never proved useful, and anyway because of the current
8282 definition, it was not possible to have several specialization of
8283 this traits, making it useless.
8284 * data/lalr1.cc (yy:traits): Remove.
8285 Inline its definitions in the parser class.
8287 2005-09-19 Akim Demaille <akim@epita.fr>

8310 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8311 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8312 is not defined. This is an awful hack, but it's enough for now.
8313 All callers changed.
8314 * tests/glr-regression-at (make_value): Args are const pointers now,
8315 to avoid GCC warning.
8316 (Duplicated user destructor for lookahead): New test. Currently
8317 skipped. It fails on my host but I'm not sure it'll always fail.
8319 2005-09-16 Akim Demaille <akim@epita.fr>
8321 * src/symtab.h (struct symbol): Declare the printer and destructor
8322 as const, to avoid accidental calls to free.

8337 2005-09-16 Akim Demaille <akim@epita.fr>
8339 * data/lalr1.cc (yylex_): Remove, inline its code.
8340 (yyreport_syntax_error_): Remove, replaced by...
8341 (yysyntax_error_): this which returns a string and leaves to the
8342 caller the call to the users' error function.
8343 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8344 Move from members of the parser object...
8345 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

8369 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8370 do anything if $@ exists. This reverts part of the 2005-07-07
8373 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8375 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8376 contains obsolete information and isn't worth distributing as a
8377 separate file anyway.
8378 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
8379 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

8386 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
8387 Suggested by twlevo@xs4all.nl.
8389 * data/glr.c (YYCHK1): Do not assume YYE is in range.

8391 Problem reported by twlevo@xs4all.nl.
8393 * doc/bison.texinfo: Don't use "filename", as per GNU coding
8394 standards. Use "file name" or "file" or "name", depending on
8396 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
8397 not to hack/foo.tab.c.
8398 (Calc++ Top Level): 2nd arg of main is not const.
8399 * data/glr.c: b4_filename -> b4_file_name.

8501 "make check" doesn't finish with "All 1 tests passed".
8503 * tests/regression.at (Token definitions): Don't rely on
8504 AT_PARSER_CHECK for data that contains backslashes. It currently
8505 uses 'echo', and 'echo' isn't portable if its argument contains
8506 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
8507 that the byte '\0xff' is not printable in the C locale; it is,
8508 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
8509 not printable, so use '\0x81' to test.
8511 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
8512 version of GCC, since the macro is used with non-GCC compilers.
8514 Fix core dump reported by Pablo De Napoli in
8515 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
8516 * tests/regression.at (Invalid inputs with {}): New test.
8517 * src/parse-gram.y (token_name): Translate type before using
8520 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
8521 the user's name space. All uses changed to __attribute__
8523 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
8524 Add __attribute__ ((__noreturn__)).
8526 * etc/clcommit: Remove. We weren't using it, and it failed
8527 "make maintainer-distcheck".
8528 * Makefile.maint: Merge from coreutils.
8529 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
8530 (syntax-check-rules): Change list of rules as described below.
8531 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

8541 Use grep -n, to make it easier to find violations.
8542 Use CVS_LIST and CVS_LIST_EXCEPT.
8543 (header_regexp, h_re): Remove.
8545 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
8546 (my-distcheck): Use more-modern GCC flags.
8547 (signatures, %.asc): Remove.
8548 (rel-files, announcement): Remove signatures.
8549 Restore old updating code, even though we don't use it, so
8550 that we're the same as coreutils.
8551 (alpha, beta, major): Depend on news-date-check.
8552 Make the upload commands.
8554 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
8555 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
8556 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
8557 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

8559 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
8560 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
8561 * tests/sets.at: Likewise.
8563 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
8564 we comment out the Autoconf version number.
8565 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
8566 it's error-prone and "make maintainer-distcheck" rejects it.
8568 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
8569 Indent calls to "error" to pacify "make maintainer-distcheck",
8570 when the calls are not intended to be translated.
8571 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
8573 * src/Makefile.am (DEFS): Use +=, to pacify
8574 "make maintainer-distcheck".
8575 (bison_SOURCES): Add scan-skel.h.
8576 (sc_tight_scope): New rule, from coreutils.
8578 * src/files.c (src_extension, header_extension):
8579 Now static, not extern.
8580 * src/getargs.c (short_options): Likewise.
8581 * src/muscle_tab.c (muscle_table): Likewise.
8582 * src/parse-gram.y (current_class, current_type, current_prec):
8584 * src/reader.c (grammar_end, previous_rule_end): Likewise.
8585 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
8586 * src/main.c (main): Cast bindtextdomain and textdomain calls to
8587 void, to avoid warning when NLS is disabled.
8588 * src/output.c: Include scan-skel.h.
8589 (scan_skel): Remove decl, since scan-skel.h does this.
8591 Indent calls to "error" to pacify "make maintainer-distcheck".
8592 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
8593 * src/reader.h (gram_end, gram_lineno): New decls to pacify
8594 "make maintainer-distcheck".
8595 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
8596 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
8597 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
8598 (skel_lex_destroy, scan_skel): Move these decls to...
8599 * src/scan-skel.h: New file.
8600 * src/uniqstr.c (uniqstr_assert):
8601 Indent calls to "error" to pacify "make maintainer-distcheck".
8603 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
8606 * tests/torture.at: Revamp to avoid misuse of atoi that
8607 "make maintainer-distcheck" complained about.
8609 * examples/extexi (message): Don't print a message more than once,
8610 and omit line-number decoration that makes Emacs compile think
8611 that informative messages are worth worrying about.
8613 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
8615 * configure.ac: Update version number.
8617 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
8619 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
8620 autogenerated by the maintainer.
8621 * examples/calc++/.cvsignore: Add *.yy.
8623 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
8624 * lib/bitset_stats.c (bitset_stats_init): Likewise.
8625 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8627 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
8629 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
8630 from maintainer-distcheck about casting the argument of 'free'.
8632 * NEWS: Mention recent yytname changes.
8633 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
8635 * bootstrap: For translations that have not yet been upgraded to
8636 the new runtime-po domain, prime the pump by extracting the
8637 relevant strings from the obsolete translations. This code can be
8638 removed once the bison-runtime domain has been translated by each
8641 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
8642 now that token names are already quoted.
8644 Fix problem reported by Anthony Heading.
8645 * data/glr.c (YYTOKEN_TABLE): New macro.
8646 (yytname): Define if YYTOKEN_TABLE.
8647 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
8648 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
8649 (YYERROR_VERBOSE): Define the same way the other skeletons do.
8650 * src/output.c (prepare_symbols): Output token_table_flag.
8652 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
8654 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
8655 again if the first call fails.
8657 * data/glr.c (yytnamerr): New function.
8658 (yyreportSyntaxError): Use it to dequote most string literals.
8659 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
8660 with other skeletons. All uses changed.
8661 (yytnameerr_): New function.
8662 (yyreport_syntax_error): Use it to dequote most string literals.
8663 * data/yacc.c (yytnamerr): New function.
8664 (yyerrlab): Use it to decode most string literals.
8665 * doc/bison.texinfo (Decl Summary, Calling Convention):
8666 Clarify quoting convention of yytname.
8667 * src/output.c (prepare_symbols): Quote all names. This undoes
8668 the 2005-04-17 change, which is now accomplished (mostly) via
8669 changes in the parsers as described above.
8670 * tests/regression.at (Token definitions, Web2c Actions):
8671 Undo most 2005-04-17 change here, too.
8673 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
8675 Fix more problems reported by twlevo@xs4all.nl.
8676 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8677 remove trailing spaces. This loses the exit status of ./types,
8678 and isn't needed since ./types shouldn't be emitting trailing
8680 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8681 as the stack isn't valid in that case.
8683 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8684 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8685 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8686 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
8688 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
8689 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
8690 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
8693 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
8694 overly-picky compilers that reject 'char *foo = "bar";'.
8696 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8697 to FILE * parameter, not to stderr. This fixes a typo introduced
8698 in the 2005-07-12 change.
8700 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
8701 warnings from GCC 4.
8703 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
8704 (yyglrShiftDefer, yysplitStack):
8705 Remove unused parameters b4_pure_formals. All uses changed.
8706 (yyglrShift): Remove unused parameters b4_user_formals.
8708 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
8710 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
8712 Destructor cleanups and regularization among the three skeletons.
8713 * NEWS: Document the behavior changes.
8714 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8715 stack before failing, as the cleanup code will do it for us now.
8716 * data/lalr1.cc (yyerrlab): Likewise.
8717 * data/glr.c (yyparse): Pop everything off the stack before
8718 freeing it, so that destructors get called properly.
8719 * data/lalr1.cc (yyreturn): Likewise.
8720 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8721 This is more consistent.
8722 * doc/bison.texinfo (Destructor Decl): Mention more reasons
8723 why destructors might be called. 1.875 -> 2.1.
8724 (Destructor Decl, Decl Summary, Table of Symbols):
8725 Some English-language cleanups for %destructor.
8726 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8727 Add output line for destructor of start symbol.
8728 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
8729 because of that same extra output line.
8731 * NEWS: Document minor wording changes in diagnostics of
8732 Bison-generated parsers.
8733 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
8734 Remove unused formals. All uses changed.
8735 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
8736 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
8737 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
8738 Rename yyoverflowab to yyexhaustedlab.
8739 When memory exhaustion occurs during syntax-error reporting,
8740 report it separately rather than in a single diagnostic; this
8742 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
8743 (Memory Exhausted): Renamed from Parser Stack Overflow.
8744 Revamp wording slightly to prefer "memory exhaustion".
8745 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
8747 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
8749 Add i18n support to the GLR skeleton. Partially fix the C++
8750 skeleton; a C++ expert needs to finish this. Remove debugging
8751 msgids; there's little point to having them translated, since they
8752 can be understood only by someone who can read the
8753 (English-language) source code.
8755 Generate runtime-po/bison-runtime.pot automatically, so that we
8756 don't have to worry about garbage getting in that file. We'll
8757 make sure after the next official release that old msgids don't
8759 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
8761 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
8763 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8764 Fix typos in explanations of the runtime file.
8765 * bootstrap: Change gettext keyword from YYI18N to YY_.
8766 Use standard Makefile.in.in in runtime-po, since we'll arrange
8767 for backward-compatible bison-runtime.po files in a different way.
8768 * data/glr.c (YY_): New macro, from yacc.c.
8769 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8770 Translate messages intended for users.
8771 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8772 the wording in the other skeletons. We don't know that the memory
8774 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8775 Use same method that yacc.c uses.
8776 Don't translate debugging messages.
8777 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8778 it doesn't work (yet), and requires C++ expertise to fix.
8779 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8780 Move defn to a more logical place, to be consistent with other
8782 Don't translate debugging messages.
8783 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8784 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8785 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8786 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
8788 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
8789 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
8791 * tests/glr-regression.at (Badly Collapsed GLR States):
8793 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8794 yylex should return 0 at EOF rather than aborting.
8796 Improve tests for stack overflow in GLR parser.
8797 Problem reported by twlevo@xs4all.nl.
8798 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
8800 (yyStackOverflow): Just longjmp, but with value 2 so that caller
8801 can handle the problem.
8802 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8803 (yyparse): New local variable yyresult to record the result.
8804 Use result of setjmp to set it, rather than storing itinto
8806 (yyDone): Remove label.
8807 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
8808 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
8809 if YYABORT is used).
8810 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
8811 yyparse status; put status > 1 into diagnostic.
8812 Check that status==2 works.
8813 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
8814 Use exit status 3 for failure to open (which shouldn't happen).
8816 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
8818 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
8819 1 on syntax error; just let yyparse do its thing.
8820 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
8821 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
8822 (Exploding the Stack Size with Alloca):
8823 (Exploding the Stack Size with Malloc):
8824 Expect exit status 2, not 1, since the parser is supposed to blow
8825 its stack. Problem reported by twlevo@xs4all.nl.
8827 * data/glr.c (yyparse): Don't assume that the initial calls
8828 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
8829 Print a stack-overflow message and fail instead.
8830 Initialize the line-number information before creating the stack,
8831 so that the stack-overflow message can report line zero safely.
8833 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
8835 Fix problems reported by twlevo@xs4all.nl.
8836 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
8837 (yyuserMerge): Provide a default case if b4_mergers is empty.
8838 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
8839 * tests/glr-regression.at
8840 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8841 Add casts to pacify C++ compilers.
8842 * tests/glr-regression.at (Improper merging of GLR delayed action
8843 sets): Declare yylex before using it.
8844 * tests/Makefile.am (maintainer-check-g++): Fix a stray
8845 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
8846 test for valgrind; valgrind is independent of g++.
8847 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
8848 for compatibility with POSIX 1003.1-2001 (if running coreutils).
8849 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
8850 Use a destructor, so that we can expand the stack. Change
8851 YYSTYPE to char * so that we can free it. Cast result of malloc.
8853 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8855 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
8856 a valgrind failure. Problem reported by twlevo@xs4all.nl.
8858 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
8860 * PACKAGING: New file, suggested by Bruno Haible and taken from
8861 similar wording in gettext's PACKAGING file.
8862 * NEWS: Mention PACKAGING.
8863 * Makefile.am (EXTRA_DIST): Add PACKAGING.

8867 * NEWS: Document recent i18n improvements.
8868 * bootstrap: Get runtime translations into runtime-po.
8869 Create runtime-po files automatically, if possible.
8870 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
8871 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
8872 does not infringe on the user's name space.
8873 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
8874 * doc/bison.texinfo (Internationalization): Revamp the English
8875 and Texinfo syntax a bit, to try to make it clearer.
8876 (Bison Options, Option Cross Key): Mention --print-localedir.
8877 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
8878 YYENABLE_NLS. Quote a bit more.

8888 * runtime-po/Makevars: Likewise.
8889 * runtime-po/LINGUAS: Likewise.
8890 * runtime-po/de.po: Likewise; we will rely on the translation project
8891 to maintain this, so "bootstrap" should get it.
8892 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
8894 * src/main.c (main): Bind the bison-runtime domain, too.
8896 2005-07-12 Bruno Haible <bruno@clisp.org>
8898 * data/yacc.c: Include <libintl.h> when NLS is enabled.
8899 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
8900 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
8901 * runtime-po: New directory.
8902 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
8903 $(DOMAIN).pot-update rule, so that old messages are never dropped.
8904 * runtime-po/Rules-quot: New file, copied from po/.
8905 * runtime-po/quot.sed: Likewise.
8906 * runtime-po/boldquot.sed: Likewise.

8917 * Makefile.am (SUBDIRS): Add runtime-po.
8918 (aclocaldir, aclocal_DATA): New variables.
8919 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
8921 * src/getargs.c (usage): Document --print-localedir option.
8922 (PRINT_LOCALEDIR_OPTION): New enum item.
8923 (long_options): Add --print-localedir option.
8924 (getargs): Handle --print-localedir option.
8925 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
8926 (Internationalization): New section.
8928 2005-07-12 Akim Demaille <akim@epita.fr>
8930 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
8931 for consistency with the rest of the code.
8932 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
8935 2005-07-12 Akim Demaille <akim@epita.fr>
8937 * src/parse-gram.y: Use %printer instead of YYPRINT.
8939 2005-07-12 Akim Demaille <akim@epita.fr>
8941 * src/symtab.h, src/symtab.c (symbol_print): New.
8942 * src/symlist.h, src/symlist.c (symbol_list_print): New.
8943 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
8945 2005-07-12 Akim Demaille <akim@epita.fr>
8947 * data/glr.c (b4_syncline): Fix (swap) the definitions of
8948 b4_at_dollar and b4_dollar_dollar.
8950 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
8952 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
8953 and Pennello's paper.
8955 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
8957 * data/yacc.c (yyparse): Undo previous patch. Instead,
8958 set yylsp[0] and yyvsp[0] only if the initial action
8959 sets yylloc and yylval, respectively.
8961 * data/yacc.c (yyparse): In the initial action, set
8962 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
8963 This avoids the use of undefined variables if the initial
8964 action does not set yylloc and/or yylval.
8966 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8968 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
8969 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
8970 Remove from CVS. These files are automatically generated.
8971 * examples/extexi: Clarify that this file is now part of Bison,
8972 not GNU M4, and that it works with any POSIX-compatible Awk.
8973 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
8974 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
8975 so that we also get calc++-parser.yy. Geneate it.
8976 Use $(AWK), not gawk, since any conforming Awk will do.
8977 Put comment before action, since older 'make' can't handle comment
8979 $(BUILT_SOURCES): List all built sources, not just some of them.
8980 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
8981 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
8982 $($(calc_sources_generated)): Remove unnecessary test for existence
8983 of target. (This had a shell syntax error anyway; a stray "x".)
8984 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
8986 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
8988 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
8989 implied by the other modules.
8991 2005-07-06 Akim Demaille <akim@epita.fr>
8993 Bind examples/calc++ to the package.
8994 * examples/calc++/Makefile: Remove, replaced by...
8995 * examples/calc++/Makefile.am: ... this new file.
8996 * examples/calc++/test: Remove input.
8997 * examples/calc++/compile: Remove.
8998 * examples/Makefile.am: New.
8999 * configure.ac, Makefile.am: Adjust.
9000 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
9002 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
9004 * data/glr.c (yyFail): Drastically simplify; since the format argument
9005 never had any % directives, we can simply pass it to yyerror.
9006 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
9007 be modified later, as that is the usual style in glr.c.
9008 Problems reported by Paul Hilfinger.
9010 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
9011 and size overflow errors.
9012 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
9013 in case the user prolog sets feature-test macros like _GNU_SOURCE.
9014 (YYSIZEMAX): New macro.
9015 (yystpcpy): New function, taken from yacc.c.
9016 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9017 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9018 so that we don't have to maintain their signatures.
9019 (yyFail): Check for buffer overflow, by using vsnprintf rather
9020 than vsprintf. Allocate a bigger buffer if possible.
9021 Report an error if buffer allocation fails.
9022 (yyStackOverflow): New function.
9023 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9024 the initialization was successful. It might fail if storage was
9026 (yyexpandGLRStack): Add more checks for storage allocation failure.
9027 Use yyStackOverflow to report failures.
9028 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
9029 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
9030 Don't assume stack number fits in int.
9031 (yysplitStack): Check for storage allocation failure.
9032 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
9033 can print diagnostics on storage allocation failure. All callers
9035 (yyresolveValue): Use yybool for boolean.
9036 (yyreportSyntaxError): Check for size-calculation overflow.
9037 This code is taken from yacc.c.
9038 (yyparse): Check for storage allocation errors when allocating
9041 2005-07-05 Akim Demaille <akim@epita.fr>
9043 Extract calc++ from the documentation.
9044 * doc/bison.texinfo (Calc++): Add the extraction marks.
9045 * examples/extexi: New, from the aborted GNU Programming 2E.
9046 Separate the different paragraph of a file with empty lines.
9047 * examples/Makefile: Use it to extract the whole calc++ example.
9049 2005-06-24 Akim Demaille <akim@epita.fr>
9051 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
9054 2005-06-22 Akim Demaille <akim@epita.fr>
9056 * doc/bison.texinfo (C++ Language Interface): First stab.
9057 (C++ Parsers): Remove.
9059 2005-06-22 Akim Demaille <akim@epita.fr>
9061 * data/lalr1.cc (yylex_): Honor %lex-param.
9063 2005-06-22 Akim Demaille <akim@epita.fr>
9065 Start a set of simple examples.
9066 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
9067 * examples/calc++/calc++-driver.hh,
9068 * examples/calc++/calc++-parser.yy,
9069 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
9070 * examples/calc++/compile, examples/calc++/test: New.
9072 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
9074 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
9075 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
9076 which stems from the 2005-05-27 patch.
9078 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9080 * data/glr.c: Modify treatment of unused parameters to permit use
9081 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
9083 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
9085 Fix infringement on user name space reported by Janos Zoltan Szabo.
9086 * data/yacc.c (yyparse): strlen -> yystrlen.
9088 2005-05-30 Akim Demaille <akim@epita.fr>
9090 * data/lalr1.cc (_): New.
9091 Translate the various messages.
9093 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
9095 Fix infringement on user name space reported by Bruno Haible.
9096 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9097 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9098 the user's name space.
9099 (alloca): Include <stdlib.h> to get it, if it's not built in.
9100 (YYMALLOC, YYFREE): Define only if needed.
9101 (malloc, free): Declare, but only if needed, as this infringes on
9102 the user name space.
9104 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
9106 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
9107 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
9109 * lib/ebitset.c (min, max): Undef before defining.
9110 * lib/vbitset.c (min, max): Likewise.
9111 * lib/subpipe.c (create_subpipe): Save local variables in case
9112 vfork clobbers them.
9114 2005-05-24 Bruno Haible <bruno@clisp.org>
9116 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
9117 error message syntax used by gcc-4.0.
9119 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
9121 * README: Mention m4 1.4.3. Remove obsolete advice about
9122 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
9124 * bootstrap: Remove workaround for problem I encountered with
9125 gettext 0.14.1; it seems to be fixed now.
9127 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
9129 * NEWS: Version 2.0a.
9131 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
9132 the previous change.
9134 Various maintainer cleanups.
9135 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9136 conftest*, for benefit of CVS commands run at the same time as
9137 "configure". Add build-aux, since "bootstrap" now creates it and
9139 * Makefile.cfg (move_if_change): Remove.
9140 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9141 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

9146 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
9148 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
9149 this is now the recommended name.
9150 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
9151 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9152 ylwrap. These files now go into build-aux.
9153 * config/move-if-change: Remove.
9154 * config/prev-version.txt: Bump from 1.75 to 2.0.
9156 * bootstrap: Add stdio-safer, unistd-safer modules.
9157 Remove m4/glibc2.m4 (introduced by latest gnulib, but
9159 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
9160 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9161 * lib/subpipe.c: Include "unistd-safer.h".
9162 (create_subpipe): Make sure all the newly-created
9163 file descriptors are > 2, so that diagnostics don't
9164 get sent down them (which might cause Bison to hang, in theory).
9165 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
9166 * src/files.c (xfopen): Use fopen_safer, not fopen.
9168 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
9169 yesterday's yacc.c fix.
9171 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
9173 * data/glr.c, data/lalr1.cc: Update copyright date.
9175 Fix a destructor bug reported by Wolfgang Spraul in
9176 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
9177 * data/yacc.c (yyabortlab): Don't call destructor, and
9178 don't set yychar to EMPTY.
9179 (yyoverflowlab): Don't call destructor.
9180 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
9181 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
9182 since we no longer output the message "discarding lookahead token
9185 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9187 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
9188 fix a small glitch in debugging output.
9189 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
9190 after YY_SYMBOL_PRINT where needed.
9192 (struct yyGLRState): Add some comments.
9193 (struct yySemanticOption): Add some comments.
9194 (union yyGLRStackItem): Add comment.
9196 (yymergeOptionSets): Correct this to properly perform the union,
9197 avoiding infinite reported by Michael Rosien.

9241 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
9243 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
9244 Problem reported by Ralf Menzel.
9246 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9248 * tests/actions.at: Test that stack overflow invokes destructors.
9249 From Marcus Holland-Moritz.
9250 * data/yacc.c (yyerrlab): Move the code that destroys the stack
9252 (yyreturn): to here. That way, destructors are called properly
9253 even if the stack overflows, or the user calls YYACCEPT or
9254 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
9255 (yyoverflowlab): Destroy the lookahead.
9257 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
9259 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
9261 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
9263 * NEWS: Bison-generated C parsers no longer quote literal strings
9264 associated with tokens.
9265 * src/output.c (prepare_symbols): Don't escape strings,
9266 since users don't want to see C escapes.
9267 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9269 * tests/input.at (Torturing the Scanner): Likewise.
9270 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9272 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9274 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9275 the data size is known to be too small and we can't increase it.
9276 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9278 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9280 * src/parse-gram.y: Include quotearg.h.
9281 (string_as_id): Quote $1 before using it as a key, since the
9282 lexer no longer quotes it for us.
9283 (string_content): Don't strip quotes, since lexer no longer
9285 * src/scan-gram.l: Include quotearg.h.
9287 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9288 a key, since the rest of the lexer doesn't quote it.
9289 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9290 * tests/regression.at (Token definitions): Check for backslashes
9293 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9294 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9295 (yyparse): Revamp code to generate long syntax error message, to
9296 make it easier to translate, and to avoid problems with arithmetic
9297 overflow. Change "virtual memory" to "memory" in diagnostic, since
9298 we don't know whether the memory is virtual.
9300 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9302 * NEWS: Bison-generated C parsers now use the _ macro to
9304 * data/yacc.c (_) [!defined _]: New macro.
9305 All English strings wrapped inside this macro.
9306 * doc/bison.texinfo (Bison Parser): Document _.
9307 * po/POTFILES.in: Include src/parse-gram.c, since it now
9308 includes translateable strings that parse-gram.y doesn't.
9310 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9312 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9313 reverting the 2004-10-11 change to this function.
9314 (symbol_check_alias_consistency): Don't call symbol_type_set
9315 if the type name is already correct.
9316 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9318 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9320 * tests/regression.at (Token definitions): Don't use a token named
9321 c, as that generates a "#define c ..." that runs afoul of buggy
9322 stdlib.h that uses the identifier c as a member of struct
9323 drand48_data. Problem reported by Horst Wente.
9325 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9327 * bootstrap: Change translation URL from
9328 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
9329 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
9330 redirection glitches. Problem reported by twlevo@xs4all.nl.
9332 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9334 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9335 after operands; POSIX says this isn't portable for the c99 command.
9337 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9339 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9340 immediately if a data overrun has occurred; this may help us track
9341 down what may be a spurious failure on MacOS.
9343 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9345 Respond to problems reported by twlevo@xs4all.nl.
9347 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9349 * src/vcg.h: Comment fix.
9350 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9351 (G_CMAX): Change to -1 instead of INT_MAX.
9353 * data/yacc.c (yyparse): Omit spaces before #line.
9355 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9357 * src/tables.c (state_number_to_vector_number): Put it inside an
9358 "#if 0", since it's not currently used. Problem reported by
9361 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9363 * src/output.c (escaped_output): Renamed from
9364 escaped_file_name_output, since we now use it for symbol tags as
9365 well. All uses changed.
9366 (symbol_destructors_output, symbol_printers_output):
9367 Escape symbol tags too.
9368 Problem reported by Matyas Forstner in
9369 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9371 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9373 * src/output.c (user_actions_output, token_definitions_output,
9374 symbol_destructors_output, symbol_printers_output): Likewise.
9375 * src/reader.c (prologue_augment): Likewise.
9376 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
9378 * src/vcg.c (output_edge): Don't quote linestyle arg.
9379 Problem reported by twlevo@xs4all.nl.
9381 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
9383 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
9384 example, reported by Derek M Jones. Also, make the example even
9385 more outrageous, to better illustrate how bad the problem is.
9387 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
9389 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
9390 putsym. Typo reported by Sebastian Piping.
9392 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9394 * doc/bison.texinfo (Language and Grammar): some -> same
9395 (Epilogue): int he -> in the
9396 Typos reported by Sebastian Piping via Justin Pence.
9398 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9400 * tests/glr-regression.at (Improper handling of embedded actions
9401 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
9402 embedded actions and $-N in GLR parsers", work around an Autoconf bug
9403 with dollar signs in test names.
9404 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
9405 for a similar reason.
9407 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9409 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
9410 wants to redefine G_VIEW.
9412 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
9414 * src/vcg.c (get_view_str): Remove case for normal_view.
9415 Problem reported by twlevo@xs4all.nl.
9417 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
9419 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
9420 Problem reported by twlevo@xs4all.nl.
9422 * doc/bison.texinfo: Change @dircategory from "GNU programming
9423 tools" to "Software development". Requested by Richard Stallman
9426 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
9428 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
9429 Problem reported by twlevo@xs4all.nl.
9431 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9433 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
9434 keyword; it's not needed with modern compilers, and it doesn't
9435 affect correctness with older compilers. Suggested by
9438 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
9440 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
9441 gcc -Wswitch-default.
9442 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9443 * data/yacc.c (yyparse): Likewise.
9445 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
9447 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
9448 already. Let config.h define any nonstandard values.
9450 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
9452 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
9453 for the benefit of slower hosts. Problem reported by
9456 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
9458 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
9459 being defined and not used.
9460 * data/lalr1.cc (yyparse): Likewise.
9461 Use "if (false)" rather than "if (0)".
9463 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
9465 * TODO: Mention that we should allow NUL bytes in tokens.
9467 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
9469 * src/scan-skel.l (<<EOF>>): Don't close standard output.
9470 Problem reported by Hans Aberg.
9472 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
9474 * src/getargs.c (version): Happy new year; update overall
9475 program copyright date from 2004 to 2005.
9477 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
9478 Problem reported by Hans Aberg.
9479 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
9480 (Output file names.): Add a test for the case when standard output
9483 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
9485 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
9486 to fix an oversight in the Bison 2.0 manual.
9488 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
9490 * NEWS: Version 2.0. Reformat the existing news items since
9491 1.875, so that related items are grouped together.
9492 * configure.ac (AC_INIT): Bump version to 2.0.
9493 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
9495 * tests/torture.at (Exploding the Stack Size with Alloca): Set
9496 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
9497 otherwise, we're not testing alloca. Unfortunately there's no
9498 simple way to consult HAVE_ALLOCA here.
9500 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
9503 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
9504 hand. This avoids a warning about comparing int to size_t when
9505 GCC warnings are enabled.
9507 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
9509 * NEWS: Bison-generated parsers no longer default to using the
9510 alloca function (when available) to extend the parser stack, due
9511 to widespread problems in unchecked stack-overflow detection.
9512 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
9513 responsibility to set it to a positive value. This lets the user
9514 specify a value that is not a preprocessor constant.
9515 * data/yacc.c (YYMAXDEPTH): Likewise.
9516 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
9517 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
9518 to be a compile-time constant. However, explain the constraints on it.
9519 Also, explain the constraints on YYINITDEPTH.
9520 (Table of Symbols): Explain that alloca is no longer the default.
9521 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
9524 * doc/bison.texinfo (Location Default Action): Mention that n must
9525 be zero when k is zero. Suggested by Frank Heckenbach.
9527 2004-12-22 Akim Demaille <akim@epita.fr>
9529 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
9530 (parser::state_type, parser::semantic_type, parser::location_type):
9531 Private, not public.
9532 (parser::parse): Return ints, not bool.
9533 Returning a bool introduces a problem: 0 corresponds to false, and
9534 it seems weird to return false on success. Returning true changes
9535 the conventions for yyparse.
9536 Alternatively we could return void and send an exception.
9537 There is no clear consensus (yet?).
9538 (state_stack, semantic_stack, location_stack): Rename as...
9539 (state_stack_type, semantic_stack_type, location_stack_type): these.
9540 Private, not public.
9541 * tests/c++.at: New.
9542 * tests/testsuite.at, tests/Makefile.am: Adjust.
9544 2004-12-21 Akim Demaille <akim@epita.fr>
9546 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
9548 2004-12-21 Akim Demaille <akim@epita.fr>
9550 Don't impose std::string for filenames.
9552 * data/lalr1.cc (b4_filename_type): New.
9553 (position::filename): Use it.
9554 (parser.hh): Move the inclusion of stack.hh and location.hh below
9555 the user code, so that needed headers for the filename type can be
9557 Forward declare them before the user code.
9558 * tests/Makefile.am (check-local, installcheck-local): Pass
9559 TESTSUITEFLAGS to the TESTSUITE.
9561 2004-12-20 Akim Demaille <akim@epita.fr>
9563 Use more STL like names: my_class instead of MyClass.
9565 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
9566 (SemanticStack, SemanticType, StateStack, StateType)
9567 (TokenNumberType, Stack, Slice, Traits, Parser::location)
9568 (Parser::value): Rename as...
9569 (location_stack, location_type, rhs_number_type, semantic_stack)
9570 (semantic_type, state_stack, state_type, token_number_type, stack)
9571 (slice, traits, parser::yylloc, parser::yylval): these.
9573 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
9575 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
9577 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
9578 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
9580 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
9582 Remove uses of 'short int' and 'unsigned short int'. This raises
9583 some arbitrary limits. It uses more memory but nowadays that's
9584 not much of an issue.
9586 This change does not affect the generated parsers; that's a different
9587 task, as some users will want to conserve memory there.
9589 Ideally we should use size_t to represent all object counts, and
9590 something like ptrdiff_t to represent signed differences of object
9591 counts; but that will require more code-cleanup than I have the
9592 time to do right now.
9594 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
9595 Use size_t, not int or short int, to count objects.
9596 * src/closure.c (nritemset, closure): Likewise.
9597 * src/closure.h (nritemset, closure): Likewise.
9598 * src/nullable.c (nullable_compute): Likewise.
9599 * src/print.c (print_core): Likewise.
9600 * src/print_graph.c (print_core): Likewise.

9603 * src/tables.c (default_goto, goto_actions): Likewise.
9605 * src/gram.h (rule_number, rule): Use int, not short int.
9606 * src/output.c (prepare_rules): Likewise.
9607 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
9608 errs, reductions): Likewise.
9609 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
9611 * src/tables.c (vector_number, tally, action_number,
9612 ACTION_NUMBER_MINIMUM): Likewise.
9613 * src/output.c (muscle_insert_short_int_table): Remove.
9615 2004-12-17 Akim Demaille <akim@epita.fr>
9617 * data/lalr1.cc: Extensive Doxygenation.
9618 (error_): Rename as...
9619 (error): this, since it is visible to the user.
9621 (Parser::message): Now an automatic variable from...
9622 (Parser::yyreport_syntax_error_): here.
9623 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
9625 * tests/input.at: Escape $.
9627 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
9629 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
9630 Parenthesize rhs to avoid obscure problems with mistakes like
9631 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
9632 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9633 b4_rhs_location): Likewise.
9634 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9635 b4_rhs_location): Likewise.
9637 2004-12-16 Akim Demaille <akim@epita.fr>
9639 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
9640 yacc.c: be sure to stay within yycheck_.
9641 * tests/actions.at: Re-enable C++ tests.
9643 2004-12-16 Akim Demaille <akim@epita.fr>
9645 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
9648 2004-12-16 Akim Demaille <akim@epita.fr>
9650 Use #define to handle the %name-prefix.
9652 * data/glr.c, data/yacc.c: Comment changes.
9653 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
9654 so that one can refer to yylex in the parser file, and have it
9655 renamed, as is the case with other skeletons.
9657 2004-12-16 Akim Demaille <akim@epita.fr>
9659 Move lalr1.cc internals into yy*.

9679 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
9681 Fix some problems reported by twlevo at xs4all.
9682 * src/symtab.c (symbol_new): Report an error if the input grammar
9683 contains too many symbols. This is better than calling abort() later.
9684 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
9685 (struct node, struct graph):
9686 Rename member expand to stretch. All uses changed.
9687 (struct graph): Remove member layoutalgorithm. All uses removed.

9693 2004-12-15 Akim Demaille <akim@epita.fr>
9695 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
9696 Add more Doxygen comments.
9697 (symprint_, stack_print_, reduce_print_, destruct_, pop)
9698 (report_syntax_error_, translate_): Rename as...
9699 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
9700 (yypop_, yyreport_syntax_error_, yytranslate_): this.
9702 2004-12-15 Akim Demaille <akim@epita.fr>
9704 * data/lalr1.cc (lex_): Rename as...
9706 Move the trace here.
9707 Take the %name-prefix into account.
9708 Reported by Alexandre Duret-Lutz.
9710 2004-12-15 Akim Demaille <akim@epita.fr>
9712 Simplify the C++ parser constructor.
9714 * data/lalr1.cc (debug_): Rename as...
9715 (yydebug_): so that the parser's internals are always in the yy*
9718 (b4_parse_param_decl): Remove the leading comma as it is now only
9719 called as unique argument list.
9720 (Parser::Parser): Remove the constructor accepting a location and
9721 an initial debugging level.
9722 Remove from the other ctor the argument for the debugging level.
9723 (debug_level_type, debug_level, set_debug_level): New.
9725 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
9728 2004-12-15 Akim Demaille <akim@epita.fr>
9730 Remove b4_root related material: failure experiment
9731 (which goal was to allow to derive from a class).
9733 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
9734 definitions and uses.
9736 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
9738 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
9739 not 2, since it's not portable to subtract 1 from the start of an
9740 array. The new item 0 is never set or used. All uses changed.
9742 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
9743 the default definition of YYLLOC_DEFAULT. Problem reported
9744 by Frank Heckenbach.
9746 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
9748 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
9749 the normal case and one for the error case. Just use the
9750 first one uniformly. Problem reported by Frank Heckenbach.
9751 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
9752 use exactly the same macro in both places.
9753 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
9754 so that the normal-case YYRHSLOC works for the error case too.
9756 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
9757 (YYLLOC_DEFAULT): Use the same macro as glr.c.
9758 * doc/bison.texinfo (Location Default Action): Don't claim that
9759 we have an array of locations. Use the same macro for both glr
9760 and lalr parsers. Mention YYRHSLOC. Mention what happens when
9763 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9765 * HACKING: Update email addresses to send announcements to.
9767 * configure.ac (AC_INIT): Bump version to 1.875f.
9769 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9771 * NEWS: Version 1.875e.
9772 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
9774 * src/scan-skel.l: Include "complain.h", for "fatal".
9776 * src/relation.h (relation_print, relation_digraph):
9777 Relation sizes are of type relation_node, not size_t (this is
9778 merely a doc fix, since the two types are equivalent).
9779 (relation_transpose): Relation sizes are of type relation_node,
9781 * src/relation.c: Likewise.
9782 (top, infinity): Now of type relation_node, not int.
9783 (traverse, relation_transpose): Use relation_node, not int.
9785 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
9786 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
9787 (yyparse): Remove unused local introduced in 2004-10-25 patch.
9789 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
9790 specifying whether the test should be skipped. Use it tp
9791 specify that the [%defines %skeleton "lalr1.cc"] tests currently
9792 fail on some hosts, and should be skipped.
9794 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9796 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
9797 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
9798 unless otherwise specified below.
9800 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
9801 to allocate kernel_base, kernel_items, kernel_size, since
9802 they needn't be initialized to 0.
9803 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
9804 * src/closure.c (new_closure): Likewise, for itemset.
9805 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

9820 (goto_actions): Likewise for state_count.
9821 (pack_table): Likewise for base, pos, check.
9822 (tables_generate): Likewise for width.
9824 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
9825 for initial core. Just have a separate core, so we needn't worry
9826 about whether kernel_size and kernel_base are initialized.
9828 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
9829 kernel_size, kernel_items): Remove unnecessary initialization.
9830 * src/conflicts.c (conflicts): Likewise.

9834 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
9835 conflrow, conflict_table, conflict_list, table, check):
9838 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
9839 This is because all callers pass unsigned int.
9840 * src/closure.h (new_closure): Likewise.
9842 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
9843 (build_relations): Initialize includes[i] in all cases.
9844 * src/reader.c (packgram): Always initialize rules[ruleno].prec
9845 and rules[ruleno].precsym. Initialize members in order.
9846 * src/relation.c (relation_transpose): Always initialize new_R[i]
9848 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
9850 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
9851 conflict_list[0] was always 0, but now it isn't initialized.
9853 * src/table.c (table_grow): When conflict_table grew, the grown
9854 area wasn't cleared. Fix this.
9856 * lib/.cvsignore: Add strdup.c, strdup.h.
9857 * m4/.cvsignore: Add strdup.m4.
9859 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
9861 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
9862 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
9863 GOTO_NUMBER_MAXIMUM, since we occasionally compute
9864 ngotos + 1 without checking for overflow.
9865 (build_relations): Use END_NODE, not -1, to denote end of edges.
9866 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
9867 build_relations): Use goto_number, not int, for goto numbers.
9868 * src/tables.c (save_column, default_goto): Likewise.
9870 2004-11-23 Akim Demaille <akim@epita.fr>
9872 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
9873 of #defining from yystype.
9874 Don't typedef yystype, C++ does not need it.
9875 This lets it possible to forward declare it as union.
9877 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
9879 * bootstrap (gnulib_modules): Add extensions.
9880 Problem reported by Jim Meyering.
9882 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
9884 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
9885 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
9886 src/system.h, src/tables.c: XFREE -> free, to accommodate
9887 recent change to gnulib xalloc.h.
9888 Problem reported by Jim Meyering.
9890 2004-11-17 Akim Demaille <akim@epita.fr>
9892 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
9894 2004-11-17 Akim Demaille <akim@epita.fr>,
9895 Alexandre Duret-Lutz <adl@gnu.org>
9897 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
9900 Use it instead of cdebug_.
9901 (Parser::debug_stream, Parser::set_debug_stream): New.
9902 (Parser::symprint_): Define cdebug_ for temporary backward
9904 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
9907 2004-11-17 Akim Demaille <akim@epita.fr>
9909 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
9910 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
9911 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
9912 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
9914 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
9916 * data/glr.c (yyloc_default): Remove; not used.
9917 Problem reported by Frank Heckenbach.
9919 2004-10-25 Akim Demaille <akim@epita.fr>
9921 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
9922 Introduce another definition to address simple location arrays.
9923 (yyGLRStack): New member: yyerror_range.
9924 (yyrecoverSyntaxError, yyparse): Update it.
9925 (yyrecoverSyntaxError): Use it when shifting the error token to
9926 have an accurate range, equivalent to the one computed by both
9927 yacc.c and lalr1.cc.
9928 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
9929 that column numbers start at column 0, as per GNU Coding
9930 Standards, the others tests, and the doc.
9931 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
9932 Adjust to the above change (first column is 0).
9933 And adjust the location of the "<error>", now covering the whole
9936 2004-10-22 Akim Demaille <akim@epita.fr>
9937 and Paul Eggert <eggert@cs.ucla.edu>
9939 Remove some arbitrary limits on goto numbers and relations.
9940 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
9941 initial values, since they're never used.
9942 (set_goto_map): ngotos is now unsigned, so test for overflow
9943 by seeing whether it wraps around to zero.
9944 * src/lalr.h (goto_number): Now size_t, not short int.
9945 (GOTO_NUMBER_MAXIMUM): Remove.
9946 * src/relation.c (relation_print, traverse, relation_transpose):
9947 Check for END_NODE rather than looking at sign.
9948 * src/relation.h (END_NODE): New macro.
9949 (relation_node): Now size_t, not short int.
9951 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
9953 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
9954 keyword, not an identifier. Problem reported by Baron Schwartz in
9955 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
9957 2004-10-11 Akim Demaille <akim@epita.fr>
9959 * src/symtab.c (symbol_check_alias_consistency): Also check
9960 type names, destructors, and printers.
9961 Reported by Alexandre Duret-Lutz.
9962 Recode the handling of associativity and precedence in terms
9963 of symbol_precedence_set.
9964 Accept no redeclaration at all, not even equal to the previous
9966 (redeclaration): New.
9967 Use it to factor redeclaration complaints.
9968 (symbol_make_alias): Don't set the type of the alias, let
9969 symbol_check_alias_consistency do it as for other features.
9970 * src/symtab.h (symbol): Add new member prec_location, and
9972 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
9973 * tests/input.at (Incompatible Aliases): New.
9975 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
9977 .cvsignore fixes to accommodate gnulib changes,
9978 and the practice of naming build directories "_build".
9979 * .cvsignore: Add "_*". Sort.
9980 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
9981 * m4/.cvsignore: Add "*_gl.m4".
9983 2004-10-06 Akim Demaille <akim@epita.fr>
9985 * src/parse-gram.y (add_param): Fix the truncation of trailing
9988 2004-10-05 Akim Demaille <akim@epita.fr>
9990 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9991 whether the reducion was empty or not. This leaves room to
9992 improve the use of YYLLOC_DEFAULT in such a case.
9993 lalr1.cc is still experimental, so changing this is acceptable.
9994 And finally, there are probably not many users who changed the
9995 handling of locations in GLR, so changing is admissible too.
9997 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
9998 empty reduction, set @$ to an empty location ending the previously
10000 Adjust uses to make sure the code is triggered on empty
10002 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
10003 expected output: empty reductions have empty locations.
10005 2004-09-29 Akim Demaille <akim@epita.fr>
10007 * data/lalr1.cc: Move towards a more standard C++ coding style
10008 for templates: Class < T > -> Class<T>.
10010 2004-09-29 Akim Demaille <akim@epita.fr>
10012 * data/lalr1.cc: Reinstall the former ctor, for sake of
10013 compatibility, but warn it will be removed.
10014 Move towards a more standard C++ coding style (i.e., type *var ->
10017 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
10019 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
10020 since it's less likely to work if NULs are involved in the future.
10022 2004-09-27 Akim Demaille <akim@epita.fr>
10024 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
10026 2004-09-27 Akim Demaille <akim@epita.fr>
10028 * data/lalr1.cc (b4_parse_param_decl_1): New.
10029 (b4_parse_param_decl): Use it to have different names between attribute
10030 and argument names.
10031 (b4_cc_constructor_call): Likewise.
10033 2004-09-24 Akim Demaille <akim@epita.fr>
10035 * src/parse-gram.y (add_param): Strip the leading and trailing
10036 blanks from a formal argument declaration.
10037 (YY_LOCATION_PRINT): New.
10039 2004-09-24 Akim Demaille <akim@epita.fr>
10041 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
10042 after the location.
10044 2004-09-24 Akim Demaille <akim@epita.fr>
10046 * doc/bison.texinfo (Table of Symbols): Sort.
10048 2004-09-21 Akim Demaille <akim@epita.fr>
10050 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
10051 the useless parentheses.
10052 Suggested by Paul Eggert.
10054 2004-09-20 Akim Demaille <akim@epita.fr>
10056 Let the initial-action act on the look-ahead, and use it for the
10057 "initial push" (corresponding to an hypothetical beginning-of-file).
10058 And let lalr1.cc honor %initial-action.
10060 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
10062 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10063 (Parser::Parser): Remove the ctor that used to initialize it.
10064 (Parser::parse): Like in the other skeletons, issue the "starting
10065 parse" message before any action.
10066 Honor %initial-action.
10067 Initialize the stacks with the lookahead.
10068 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10070 Push them in the stacks.
10071 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
10073 2004-09-20 Akim Demaille <akim@epita.fr>
10075 * doc/bison.texinfo (Initial Action Decl): New.
10077 2004-09-20 Akim Demaille <akim@epita.fr>
10079 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
10080 clearer criterion to define it.
10081 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
10082 When reducing on an empty RHS, use the latest stacked location as
10084 yylloc is not always available.
10085 * data/glr.c: Likewise.
10086 Also, honor initial-actions.
10088 2004-09-20 Akim Demaille <akim@epita.fr>
10090 * data/yacc.c (YY_LOCATION_PRINT): New.
10091 Define when we know YYLTYPE's structure, i.e., when the default
10092 YYLLOC_DEFAULT is used.
10093 * data/c.m4 (b4_yysymprint_generate): Use it.
10094 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
10095 value of the result.
10096 (error_start_): Replace with...
10097 (error_range_): this location array.
10098 This allows to replace code relying on the implementation of
10099 locations by portable code.
10100 * data/yacc.c (yylerrsp): Replace with...
10101 (yyerror_range): this.
10102 Every time a token is popped, update yyerror_range[0], to have an
10103 accurate location for the error token.
10104 * data/glr.c (YY_LOCATION_PRINT): New.
10105 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
10106 deference a pointer.
10107 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
10108 report the location in %printers.
10110 * src/scan-skel.l: Instead of abort, report error messages to ease
10111 understanding skeleton scanning failures.
10113 2004-09-16 Akim Demaille <akim@epita.fr>
10115 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
10116 (iterator, const_iterator): these, to be more in the C++ spirit.
10117 Also, return reverse iterators so that when displaying the stack
10118 we display its bottom first.
10119 (Parser::stack_print_, Parser::reduce_print_): Match the messages
10121 We should probably use vector here though.
10123 2004-09-16 Akim Demaille <akim@epita.fr>
10125 Have more complete shift traces.
10127 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
10128 to report Shifts instead of ad hoc YYDPRINTF invocations,
10129 including for the error token.
10130 * data/lalr1.cc (symprint_): Output the location.
10131 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10132 output the location within the %printer.
10133 Activate GLR tests, at least to make sure they compile properly.
10134 They still don't pass though.
10135 * tests/calc.at: Adjust expect verbose output, since now "Entering
10136 state..." is on a different line than the "Shifting" message.
10138 2004-09-08 Akim Demaille <akim@epita.fr>
10140 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10141 Bison directive from the Bison file to the invocation of this
10142 macro, so that these directives are passed to
10143 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10144 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10145 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10146 the extra Bison directives instead of the whole series.
10147 Change the grammar so that there are recoverable errors, and
10148 unrecoverable errors. Now we can have the parser give up before
10149 consuming the whole input. As a result we now can observe that
10150 the lookahead is freed when needed.
10151 Change the parser source to parse argv[1] instead of a hard coded
10153 Simplify yylex, and give a value and location to EOF.
10154 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10155 passed directives already coded in the file.
10156 Add some tests to check the location of "error".
10157 For some tests, the C++ parser is correct, and not yacc.c.
10158 For other tests, they provide different, but unsatisfying, values,
10159 so keep the C++ value so that at least one parser is "correct"
10160 according to the test suite.
10161 (Actions after errors): Remove, this is subsumed by the
10162 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
10164 2004-09-06 Akim Demaille <akim@epita.fr>
10166 * data/lalr1.cc: Adjust the indentation of the labels.
10167 (Parser::pop): New.
10170 2004-09-06 Akim Demaille <akim@epita.fr>
10172 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
10173 argument, an informative message.
10174 Call YY_SYMBOL_PRINT.
10175 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
10176 * data/lalr1.cc (destruct_): Likewise.
10177 In addition, no longer depend on b4_yysymprint_generate and
10178 b4_yydestruct_generate to generate these functions, do it "by
10181 2004-09-03 Akim Demaille <akim@epita.fr>
10183 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
10184 invoked, yydestruct the lookahead.
10185 * tests/calc.at (Calculator $1): Update the expected lengths of
10186 traces: there is an added line for the discarded lookahead.
10187 * doc/bison.texinfo (Destructor Decl): Some rewording.
10188 Define "discarded" symbols.
10190 2004-09-02 Akim Demaille <akim@epita.fr>
10192 * data/lalr1.cc (translate_, destruct_): No reason to be static.
10194 2004-09-02 Akim Demaille <akim@epita.fr>
10196 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
10197 (YYDSYMPRINTF): Rename as...
10198 (YY_SYMBOL_PRINT): this.
10199 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
10201 Use it instead of direct symprint_ calls.
10202 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
10205 2004-09-02 Akim Demaille <akim@epita.fr>
10207 * data/lalr1.cc (b4_yysymprint_generate): New.
10208 (symprint_): New member function, defined when YYDEBUG.
10209 Use it consistently instead of token/nterm debugging output by
10211 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
10212 %printer calls to use cdebug_ when using lalr1.cc.
10214 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
10216 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
10217 with #ifdef YYDEBUG.
10219 2004-08-26 Akim Demaille <akim@epita.fr>
10221 * doc/bison.texinfo (Implementing Loops): Rename as...
10222 (Implementing Gotos/Loops): this.
10224 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
10226 Adjust to latest gnulib.
10227 * bootstrap (gnulib_modules): Add xalloc-die.
10228 Set LC_ALL=C so that file names sort consistently.
10229 Prefer the gnulib copies of gettext.m4, glibc21.m4,
10230 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
10231 uintmax_t.m4, ulonglong.m4.
10232 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
10233 po.m4 since we are now using _gl.m4 instead.
10235 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
10237 * src/scan-action.l: Remove. Scanning of semantic actions is
10238 handled in scan-gram.l.
10240 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
10242 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
10244 * src/location.h (struct): The file member is a uniqstr.
10245 (equal_boundaries): Use UNIQSTR_EQ for comparison.
10247 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
10249 Fix bug with non-%union parsers that have printers or destructors,
10250 which led to a Bison core dump. Reported by Peter Fales in
10251 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
10253 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
10254 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
10255 not to our own type.
10256 * src/output.c (symbol_destructors_output, symbol_printers_output):
10257 Don't assume %union.
10258 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
10259 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
10260 UNION-FLAG. All callers changed.
10261 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
10262 Use type char, not unsigned int, when declaring an array of char;
10263 this lets us remove a cast.
10264 (Printers and Destructors): Add non-%union test cases.
10266 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10268 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10269 GLR writeups. E.g., avoid frenchspacing and the future tense,
10270 change "lookahead" to "look-ahead", and change "wrt" to "with
10273 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10275 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
10276 New sections, split off from the GLR Parsers section. Put the new
10277 Simple GLR Parser near the start of the GLR section, for clarity.
10278 Rewrite connective text.
10280 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
10282 * doc/bison.texinfo (Simple GLR Parsers): New section.
10284 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10286 * NEWS, TODO, doc/bison.texinfo:

10302 * src/state.c (state_rule_look_ahead_tokens_print): Renamed from
10303 state_rule_lookaheads_print.
10304 * src/state.h: Likewise.
10305 (reductions.look_ahead_tokens): Renamed from lookaheads.
10306 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from
10307 AT_DATA_LOOKAHEADS_GRAMMAR.
10309 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
10311 * README: Update location of patched M4 distribution.
10313 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>

10324 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
10326 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
10327 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

10333 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
10335 * tests/calc.at, tests/actions.at: Workaround for SGI
10336 C++ compiler. (trivial change)
10338 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10340 Spent a few hours checking out which prerequisite versions the
10341 current sources actually require. I went all the way back to
10342 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10343 a seemingly endless set of combinations of versions more recent
10344 than that. The bottom line is that the current sources require
10345 fairly recent versions of the build tools, and it'll be some work
10347 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10348 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10349 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10350 Add comments explaining why those particular versions are
10353 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
10354 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10355 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10357 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10358 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10360 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10362 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10363 0.11.5. Suggested by Bruno Haible.
10364 * bootstrap: Remove gettext version checking.
10366 * doc/bison.texinfo (Decl Summary): Also mention that %union
10367 can depend on prerequisite types. Problem reported by Tim
10370 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10372 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10373 * README-alpha: Don't tell people not to package this.
10375 * bootstrap: Don't assume $(...) works; use `...` instead.
10376 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
10379 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
10380 put into the -d output file, and mention what to do if YYSTYPE is
10381 defined as a macro.
10383 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10385 Undo change made earlier today: it caused autopoint to not bring
10386 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
10389 * bootstrap: Check that gettext version matches what's in
10390 configure.ac. Warn users to ignore robots.txt ERROR 404.
10391 * bootstrap: Undo today's earlier change (logged below).
10392 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
10394 The gettext version checking is causing more trouble than it's
10395 curing; remove it. Problem reported by Paul Hilfinger.
10397 * bootstrap: Issue a warning that one can expect a message
10398 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
10399 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
10401 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
10403 Ensure that the C++ compiler used for testing actually works on a
10404 simple test program; if not, skip the C++-related tests. Problem
10405 reported by Vin Shelton in:
10406 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

10415 * data/glr.c (yylloc): Output this macro even if locations are not
10416 being generated, as the GLR parser needs it even in that case.
10417 Problem reported by Troy A. Johnson
10418 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
10420 * configure.ac (AC_INIT): Update to 1.875e.

10425 * configure.ac (AC_INIT): Likewise.
10426 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
10428 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
10429 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
10430 lalr1.cc runs afoul of the first, and the last two are no longer
10431 supported by GCC 3.4.0.
10432 * README: Mention GNU m4 1.4 or later; mention m4 patches.
10433 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
10435 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>

10452 (unexpected_newline): New function.
10453 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate

10458 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
10459 Fix typo by replacing $1 with $option.
10460 Remove more 'intl'-related files.
10461 Don't DEFUN AM_INTL_SUBDIR twice.

10471 * src/.cvsignore: Add *.output.
10473 * src/parse-gram.y: Put copyright notice inside %{ %} so it
10474 gets copied to the output file.
10476 2004-04-28 Paul Eggert <eggert@twinsun.com>
10478 Get files from the gnulib and po repositories, instead of relying
10479 on them being in our CVS. Upgrade to latest versions of gnulib
10482 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
10483 * bootstrap: Bootstrap from gnulib and po repositories.
10484 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
10485 * README-cvs: Document these changes. Remove version numbers from
10486 mentions of build tools, since they change so often. Mention Flex.
10488 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
10489 (gl_USE_SYSTEM_EXTENSIONS): Add.
10490 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
10491 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
10493 (AC_ISC_POSIX): Remove; we no longer support this
10494 ancient OS, as it gets in the way of latest Autoconf & gnulib.
10495 (AC_HEADER_STDC): Remove: we now assume C89 or better.
10496 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
10497 Do not check for C89 headers, except for locale.h which is used
10498 by the Yacc library and must port to K&R hosts.
10499 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
10500 Do not check for C89 functions, except for setlocale which is
10501 used by the Yacc library.

10506 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
10507 AM_GNU_GETTEXT): Remove; now done by:
10508 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
10509 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
10512 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
10513 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
10514 Define to empty, as gnulib.mk will do the rest for us.

10525 (strnlen, memrchr): Remove decls; functions no longer used.
10526 Include <stpcpy.h>.

10549 Remove, as these files are now generated automatically
10550 by bootstrap or automake.
10552 * po/ChangeLog: Remove: all but one entry was a duplicate
10553 of this file, and I moved that 2000-11-02 entry here.
10555 * config/.cvsignore: Add Makefile, depcomp, install-sh.
10556 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

10576 support it. (The latest stable gzip doesn't.)
10578 2004-04-27 Paul Eggert <eggert@twinsun.com>
10580 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
10581 case, as stos_ is now used by destructors due to the 2004-02-09
10584 Remove more K&R C support.
10585 * lib/libiberty.y (PARAMS): Remove. All uses removed.

10603 with latest obstack.h.
10604 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args

10619 the union, because empty unions aren't allowed in C. Caught

10726 token so that it covers all the discarded tokens.
10727 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
10728 it can be called with `%skeleton "lalr1.cc"', and do that.
10730 2004-02-02 Paul Eggert <eggert@twinsun.com>
10732 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
10733 $(top_srcdir)/lib and ../lib. This fixes a bug reported
10734 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
10735 There's no need to mention top_builddir since Automake does that
10737 (INCLUDES): Remove, as Automake says it's obsolescent.
10738 Contents migrated into AM_CPPFLAGS as described above.
10739 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
10741 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10743 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
10744 (yyreportSyntaxError): Handle case where lookahead token is
10747 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10749 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
10750 resulting parsers are compilable with C++.
10752 2003-12-23 Paul Eggert <eggert@twinsun.com>
10754 * config/depcomp, config/install-sh: Sync with Automake 1.8.
10755 * src/output.c (output_skeleton): Rename local var.
10756 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
10757 Bison tokens, as this runs afoul of the 2003-10-07 change that
10758 disallowed NUL bytes in character constants or string literals.
10760 * tests/local.at: Require Autoconf 2.59's Autotest.
10761 * tests/testsuite.at: Don't include local.at, since we now assume
10762 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
10764 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
10765 multiple inclusion warnings.

10775 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
10777 2003-10-07 Paul Eggert <eggert@twinsun.com>
10779 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
10780 if testsuite doesn't exist.
10782 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
10783 literals, unfortunately.
10784 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
10785 Complain about NUL bytes in character constants or string literals.
10787 2003-10-05 Paul Eggert <eggert@twinsun.com>
10789 * NEWS: Don't document %no-default-prec, as it's still
10791 * doc/bison.texinfo: Document %no-default-prec only if
10792 the defaultprec flag is set. Normally it's not.
10794 2003-10-04 Paul Eggert <eggert@twinsun.com>
10796 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
10797 non-modifiable lvalue, instead of a modifiable one.
10798 * doc/bison.texinfo (Actions): Document that $$ can
10799 be assigned to. Do not claim that $$ and $N are
10800 array element references: user code should not rely on this.
10802 2003-10-01 Paul Eggert <eggert@twinsun.com>
10804 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

10814 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
10815 * src/print_graph.c (print_graph): Adjust.

10834 a typo in the 2003-08-25 patch.
10836 2003-08-27 Akim Demaille <akim@epita.fr>
10838 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
10841 2003-08-26 Akim Demaille <akim@epita.fr>
10843 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
10844 "<\#" to avoid magic from Gnus when posting parts of this script.

10850 Adjust: nerrs and errstatus is now replaced by...
10851 (Parser::nerrs_, Parser::errstatus_): New.
10853 2003-08-25 Akim Demaille <akim@epita.fr>
10855 * config/announce-gen, Makefile.cfg: New.

10858 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
10860 2003-08-25 Akim Demaille <akim@epita.fr>
10862 When reducing initial empty rules, Bison parser read an initial
10863 location that is not defined. This results in garbage, and that
10864 affects Bison's own parser. Therefore we need (i) to extend Bison
10865 to support a means to initialize this location, and (ii) to use
10866 this CVS Bison to fix CVS Bison's parser.
10868 * src/reader.h, reader.c (epilogue_augment): Remove, replace
10870 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
10871 * src/parse-gram.y: Adjust.
10872 (%initial-action): New.
10873 (%error-verbose): Since we require CVS Bison, there is no reason
10875 * src/scan-gram.l: Adjust.
10876 * src/Makefile.am (YACC): New, to make sure we use our own parser.
10877 * data/yacc.c (yyparse): Use b4_initial_action.
10879 2003-08-25 Akim Demaille <akim@epita.fr>
10881 * doc/bison.texinfo: Don't promote stdout for error messages.
10883 2003-08-25 Akim Demaille <akim@epita.fr>
10885 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
10886 From Alexandre Duret-Lutz.

10897 2003-08-25 Akim Demaille <akim@epita.fr>
10899 * data/lalr1.cc (Parser::reduce_print_): New.
10902 2003-08-25 Akim Demaille <akim@epita.fr>
10904 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
10905 error recovery loops. This patch is based on
10906 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
10907 Also, augment the similarity between lalr1.cc and yacc.c.
10908 Note: the locations of error recovery rules are not correct yet.
10910 * data/lalr1.cc: Comment changes to augment the similarity between
10911 lalr1.cc and yacc.c.
10912 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
10913 (yyerrlab1): Remove, but where it used to be (now the bottom part of
10914 yyerrlab), when hitting EOF, pop the whole stack here instead of
10915 merely falling thru the default error handling mechanism.
10916 (yyerrorlab): New label, with the old contents of YYERROR,
10917 plus the following change: pop the stack of rhs corresponding
10918 to the production that invoked YYERROR. That is how Yacc
10919 behaves (required by POSIX).
10920 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
10923 2003-08-25 Akim Demaille <akim@epita.fr>
10925 Tune local.at so that people can "autom4te -l autotest calc.at -o
10926 calc" for instance, to extract a sub test suite.
10928 * tests/testsuite.at: Move the initialization, Autotest version
10929 requirement, and AT_TESTED invocation into...
10930 * tests/local.at: here.
10931 * tests/testsuite.at: Include it for compatibility with Autoconf
10933 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
10936 2003-08-04 Paul Eggert <eggert@twinsun.com>
10938 Rework code slightly to avoid gcc -Wtraditional warnings.
10939 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
10940 The returned value is now stored in *YY0. All callers changed.
10941 * src/output.c (merge_output): Adjust to the above change.
10943 2003-07-26 Paul Eggert <eggert@twinsun.com>
10945 * data/glr.c (YYASSERT): New macro.
10946 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
10947 yyresolveStates, yyprocessOneStack):
10948 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
10949 Derived from a suggestion by Frank Heckenbach.
10951 2003-07-25 Paul Eggert <eggert@twinsun.com>
10953 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
10954 for portability to K&R C (after ansi2knr, presumably). See
10955 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
10956 by Frank Heckenbach, though I have omitted the structure-initialization
10957 part of his glr-knr.diff patch since I recall that the Portable
10958 C Compiler didn't require that change.
10960 Let the user specify how to allocate and free memory.
10961 Derived from a suggestion by Frank Heckenbach in
10962 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
10963 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
10964 All uses of free, malloc, realloc changed to use these macros,
10965 and unnecessary casts removed.
10966 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
10968 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
10970 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
10971 use s.empty() rather than s == "" to test for empty string; see
10972 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
10975 2003-06-25 Akim Demaille <akim@epita.fr>
10977 * config/depcomp, config/install-sh: Update from masters.
10979 2003-06-20 Paul Eggert <eggert@twinsun.com>
10981 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
10982 and return properly parenthesized result.
10983 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
10984 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10985 Remove unnecessary parentheses from uses.

10987 conventions for parentheses.
10989 2003-06-19 Paul Eggert <eggert@twinsun.com>
10991 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
10992 yyreportTree): Do not assume that size_t is the same width as int,
10993 when printing sizes. Print sizes using an unsigned format.
10994 Problem reported by Frank Heckenbach in
10995 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
10997 Port to Forte Developer 7 C compiler.
10998 * data/glr.c (struct YYLTYPE): If locations are not being used,
10999 declare a single dummy member, as empty structs do not conform
11001 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
11002 the Forte Developer 7 C compiler complains that end-of-loop
11003 code is not reached.
11005 2003-06-17 Paul Eggert <eggert@twinsun.com>

11017 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
11018 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
11019 Don't use 'index' in comments, as it's a builtin fn on some hosts.
11020 * lib/bitset_stats.c: Include gettext.h unconditionally, as
11021 per recent gettext manual's suggestion.
11022 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
11023 Use prototypes, not old-style definitions.

11047 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
11048 `How Can I Reset @code{yyparse}', since texinfo does not allow
11049 arbitrary @ in node names.
11051 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
11052 shouldn't be needed according to the gettext 0.12.1 documentation
11053 but which seem to be needed anyway: codeset.m4 glibc21.m4
11054 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
11055 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

11076 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
11077 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
11078 the tests right now.
11079 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
11080 yyerror are declared before use; C99 requires this.
11082 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11084 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
11086 (yyrecoverSyntaxError): Correct the logic for setting and testing
11088 Correct comment on handling EOF.
11089 Allow states with only a default reduction, rather than failing
11090 (I can't quite reconstruct why these were not allowed before).
11092 Fixes to avoid problem that $-N rules in GLR parsers can cause
11093 buffer overruns, corrupting state.
11095 * src/output.c (prepare_rules): Output max_left_semantic_context
11097 * src/reader.h (max_left_semantic_context): New variable declaration.
11098 * src/scan-gram.l (max_left_semantic_context): Define.
11099 (handle_action_dollar): Update max_left_semantic_context.
11100 * data/glr.c (YYMAXLEFT): New definition.
11101 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
11102 (yyresolveAction): Ditto.
11104 Fixes to problems with location handling in GLR parsers reported by
11105 Frank Heckenbach (2003/06/05).
11107 * data/glr.c (YYLTYPE): Make trivial if locations not used.
11108 (YYRHSLOC): Add parentheses, and define only if locations used.
11109 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
11110 locations not used.

11112 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
11114 * tests/cxx-type.at: Exercise location information; update tests
11115 to differentiate output with and without locations.
11116 Remove forward declarations of yylex and yyerror---caused errors
11117 because default YYLTYPE not yet defined.
11118 Change semantic actions to compute strings, rather than printing
11119 them directly (to test proper passing of semantics values). Change
11120 output to prefix notation and update test data and expected results.
11121 (yylex): Track locations.
11122 (stmtMerge): Return value rather than printing, and include arguments
11125 2003-06-03 Paul Eggert <eggert@twinsun.com>
11127 Avoid warnings generated by GCC 2.95.4 when Bison is
11128 configured with --enable-gcc-warnings.
11129 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
11130 yy::]b4_parser_class_name[::translate_,
11131 yy::Stack::operator[] (unsigned),
11132 yy::Stack::operator[] (unsigned) const,
11133 yy::Slice::operator[] (unsigned),
11134 yy::Slice::operator[] (unsigned) const):
11135 Rename local vars to avoid warnings.
11136 * tests/glr-regression.at (Improper handling of embedded actions
11137 and $-N in GLR parsers): Remove unused local variable from yylex.
11138 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11139 (void) as arg when not pure, since we now assume C89 when building
11140 Bison. Pacify GCC by using parameter.
11142 2003-06-02 Paul Eggert <eggert@twinsun.com>
11144 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11145 yy::Location::lines, yy::Location::columns): Rename arguments
11146 to avoid shadowing; this removes a warning generated by GCC 3.3.
11148 2003-06-01 Paul Eggert <eggert@twinsun.com>
11150 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11151 to g++, as GCC 3.3 complains if you do it.
11152 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11153 everything that WARNING_CFLAGS has, except omit warnings
11154 not suitable for C++.
11155 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11156 * tests/atlocal.in (CXXFLAGS): New var.
11157 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11159 Fix a GLR parser bug I reported in February; see
11160 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
11161 The problem was that GLR parsers did not conform to the C standard,
11162 because actions like { $1 = $2 + $3; } expanded to expressions
11163 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11164 to a local variable. The C standard says that expressions
11165 like (var = f ()) + (var = f ()) have undefined behavior.
11166 Another problem was that GCC sometimes issues warnings that
11167 yyfill and its parameters are unused.
11169 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11170 as possibly unused.
11171 (yyfill): New function.
11173 (yyuserAction): Change type of yynormal to bool, so that it matches
11174 the new yyfill signature. Mark it as possibly unused.
11177 Follow up on a bug I reported in February, where a Bison-generated
11178 parser can loop. Provide a test case and a fix for yacc.c. I
11179 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11180 The original bug report is in:

11183 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11184 macro's size was becoming unwieldy.
11185 (yyerrlab): Do not discard an empty lookahead symbol, as this
11186 might destroy garbage.
11187 (yyerrorlab): New label, with the old contents of YYERROR,
11188 plus the following change: pop the stack of rhs corresponding
11189 to the production that invoked YYERROR. That is how Yacc
11190 behaves, and POSIX requires this behavior.
11191 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11192 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11193 Define 'alarm' to do nothing if unistd.h is not available.
11194 Add a new rule "exp: '-' error;" to test the above change to
11195 data/yacc.c. Use 'alarm' to abort any test taking longer than
11196 10 seconds, as it's probably looping.
11197 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11198 Also, the new yacc.c generates two fewer diagnostics for an
11201 2003-05-24 Paul Eggert <eggert@twinsun.com>
11203 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
11204 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
11205 This fixes a problem reported by John Bowman when the Compaq/HP
11206 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
11207 -ansi -Wall -gall).
11208 * data/yacc.c (union yyalloc): Likewise.
11209 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
11211 Switch from 'int' to 'bool' where that makes sense.
11213 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
11214 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
11215 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
11216 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
11217 Return or accept bool, not int. All callers changed.
11218 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
11219 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
11220 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,
11221 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
11222 bitset_or_and_cmp_): Likewise.
11223 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
11224 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
11225 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
11226 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
11227 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
11228 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
11229 bitset_stats_or_and_cmp): Likewise.
11230 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
11231 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
11232 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
11233 ebitset_xor_cmp): Likewise.
11234 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
11235 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
11236 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
11237 lbitset_xor_cmp): Likewise.
11238 * lib/bbitset.h: Include <stdbool.h>.
11239 (struct bitset_vtable): The following members now return bool, not
11240 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
11241 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
11243 * src/conflicts.c (count_rr_conflicts): Likewise.
11244 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
11246 * lib/ebitset.c (ebitset_obstack_init): Likewise.
11247 * lib/lbitset.c (lbitset_obstack_init): Likewise.
11248 * src/getargs.c (debug_flag, defines_flag, locations_flag,
11249 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
11250 graph_flag): Likewise.
11251 * src/getargs.h (debug_flag, defines_flag, locations_flag,
11252 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
11253 graph_flag): Likewise.
11254 * src/output.c (error_verbose): Likewise.
11255 * src/output.h (error_verbose): Likewise.
11256 * src/reader.c (start_flag, typed): Likewise.
11257 * src/reader.h (typed): Likewise.
11258 * src/getargs.c (LOCATIONS_OPTION): New constant.
11259 (long_options, getargs): Use it.
11260 * src/lalr.c (build_relations): Use bool, not int.
11261 * src/nullable.c (nullable_compute): Likewise.
11262 * src/print.c (print_reductions): Likewise.
11263 * src/tables.c (action_row, pack_vector): Likewise.
11264 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
11265 * src/output.c (prepare): Use it.
11266 * src/output.c (token_definitions_output,
11267 symbol_destructors_output, symbol_destructors_output): Use string,
11268 not boolean integer, to keep track of whether to output separator.
11269 * src/print_graph.c (print_core): Likewise.
11270 * src/state.c (state_rule_lookaheads_print): Likewise.
11272 * config/install-sh: Sync from automake 1.7.5.
11274 2003-05-14 Paul Eggert <eggert@twinsun.com>
11276 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11277 semicolon after a grammar declaration, in the interest of possible
11278 future changes to the Bison input language.
11279 Do not allow a stray semicolon at the start of the grammar.
11280 (rhses.1): Allow one or more semicolons after any rule, including
11281 just before "|" as required by POSIX.
11282 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11285 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11287 %parse-param support for lalr1.cc.
11289 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11290 b4_cc_constructor_calls, b4_cc_constructor_call,
11291 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11293 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11294 parse-param arguments.
11295 (yy::b4_parser_class_name): Declare instance variables to
11296 hold parse-param arguments.
11297 * tests/calc.at: s/value/semantic_value/ because value clashes
11298 with a member of yy::b4_parser_class_name. Adjust C++ code
11299 to handle %parse-param. Enable %parse-param test in C++.
11301 2003-05-12 Paul Eggert <eggert@twinsun.com>
11303 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11304 English a bit. Fix fclose typo. Change "const char" to "char
11305 const", and use ANSI C rather than K&R for "main". Suggest
11306 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11307 and suggest yy_switch_to_buffer.
11309 2003-05-05 Paul Eggert <eggert@twinsun.com>
11311 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11312 C89. This avoids a diagnostic on compilers that define __STDC__
11313 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11314 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11316 2003-05-03 Paul Eggert <eggert@twinsun.com>
11318 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11319 Do not overrun array bounds.
11320 This should fix a bug reported today by Olatunji Oluwabukunmi in
11321 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11323 2003-04-29 Akim Demaille <akim@epita.fr>
11325 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11326 * src/getargs.c, src/getargs.h: here, as bool, not int.
11327 (nondeterministic_parser): New.
11328 * src/parse-gram.y, src/scan-gram.l: Support
11329 %nondeterministic-parser.
11330 * src/output.c (prepare): Use nondeterministic_parser instead
11331 of glr_parser where appropriate.
11332 * src/tables.c (conflict_row, action_row, save_row)
11333 (token_actions, token_actions, pack_vector): Ditto.
11335 2003-04-29 Akim Demaille <akim@epita.fr>
11337 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11339 2003-04-29 Akim Demaille <akim@epita.fr>
11341 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11342 with %pure-parser and %locations to exercise the patch from Yakov
11345 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11347 * data/yacc.c: (b4_lex_param): Corrected for the case where
11348 %lex-param is provided and %pure-parser isn't.
11350 2003-04-27 Paul Eggert <eggert@twinsun.com>
11352 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11353 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11354 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11355 if it is not defined.
11356 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11358 2003-04-26 Paul Eggert <eggert@twinsun.com>
11360 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11361 Declare to be of type suitable for the ninf value itself, not of
11362 type suitable for the corresponding table, since the latter might
11363 be unsigned but the ninf value might be negative. This fixes a
11364 bug reported by Alexandre Duret-Lutz in
11365 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11367 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11368 invokes it. We shouldn't invoke it twice because it will attempt
11369 to put error.o in the archive twice. This fixes a glitch reported
11370 by Martin Mokrejs in
11371 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11373 2003-04-21 Paul Eggert <eggert@twinsun.com>
11375 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
11378 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
11380 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
11381 Fix obvious typo that results in uncompilable GLR parsers
11382 when both %pure-parser and %locations are used. (trivial change)
11384 2003-04-17 Paul Eggert <eggert@twinsun.com>
11386 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
11387 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
11388 Do not insert the expected token via unput, as this runs afoul
11389 of a POSIX-compatibility bug in flex 2.5.31.
11390 All uses changed to BEGIN the parent state,
11391 since we no longer insert the expected token via unput.
11392 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
11393 that is no longer emitted after the above change.
11395 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
11396 the first one. This change is from Paul Hilfinger, and it fixes
11397 regression reported by Werner Lemberg in
11398 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
11400 (resolve_sr_conflict): Don't invoke state_errs_set
11401 unless one or more tokens have been explicitly made errors.
11402 Otherwise, the above change causes Bison to abort.
11404 * tests/existing.at (GNU pic Grammar): New test case, taken from
11407 2003-03-31 Akim Demaille <akim@epita.fr>
11409 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
11411 2003-03-31 Akim Demaille <akim@epita.fr>
11413 * src/output.c (prepare_symbols): Avoid trailing spaces in the
11416 2003-03-31 Akim Demaille <akim@epita.fr>
11418 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
11419 From Paul Hilfinger.
11421 2003-03-29 Akim Demaille <akim@epita.fr>
11423 * m4/error.m4: Do not put under dynamic conditions some code which
11424 expansion is under static control.
11426 2003-03-29 Akim Demaille <akim@epita.fr>
11428 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
11430 2003-03-29 Akim Demaille <akim@epita.fr>
11432 * doc/bison.texinfo (Strings are Destroyed): New.
11434 2003-03-13 Paul Eggert <eggert@twinsun.com>
11436 * .cvsignore: Add configure.lineno.
11437 * src/.cvsignore: Add yacc.
11438 * tests/.cvsignore: Add testsuite.log.
11439 * doc/fdl.texi: Sync with latest FSF version.
11441 2003-03-12 Paul Eggert <eggert@twinsun.com>
11443 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
11444 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
11445 cursor, instead of leaving it undefined. This fixes a bug
11446 reported by Tim Van Holder in
11447 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
11448 * tests/input.at (Torturing the Scanner): Test the scanner on
11449 an empty input file, which was Tim Van Holder's test case.
11451 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
11452 <sys/resource.h> can be included, include sys/time.h and
11453 sys/times.h first, if available. This works around the SunOS
11454 4.1.4 porting bug reported by Bruce Becker in
11455 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
11457 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
11458 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
11459 AC_HEADER_SYS_WAIT.
11461 Merge changes from gnulib. This was prompted because the CVS
11462 snapshot didn't build on Solaris 7 due to strnlen problems.
11464 These changes need to be merged back into gnulib:
11465 * lib/hash.c: Include <stdbool.h> unconditionally.
11466 * m4/onceonly.m4 (m4_quote): New macro.
11467 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
11468 Quote AC_FOREACH variable-expansions properly.
11469 The 2003-01-03 obstack.h change also needs merging.
11470 {end of changes requiring merging}
11472 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
11473 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
11474 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
11475 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
11476 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
11477 New files, imported from gnulib.
11478 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
11481 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
11482 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
11485 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
11487 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
11488 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
11489 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
11490 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
11491 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
11492 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
11493 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
11494 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
11495 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
11496 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
11497 (jm_PREREQ_ARGMATCH): Remove.
11498 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
11499 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
11501 * src/system.h: Include <stdbool.h> unconditionally.
11503 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
11504 assuming at least C89 in the bitset code for some time now.
11506 2003-03-03 Akim Demaille <akim@epita.fr>
11510 2003-03-02 Akim Demaille <akim@epita.fr>
11512 * doc/bison.texinfo (Table of Symbols): Reactivate the
11513 documentation for %lex-param, and %parse-param.
11515 2003-03-02 Akim Demaille <akim@epita.fr>
11517 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
11518 generate verbose error messages.
11519 Use the number of tokens as an upper bound in yytname, as it
11520 cannot be a non terminal.
11522 2003-03-02 Akim Demaille <akim@epita.fr>
11524 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
11527 2003-03-02 Akim Demaille <akim@epita.fr>
11529 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
11530 Use them to exercise yycheck overrun.
11531 Based on Andrew Suffield's grammar.
11533 2003-03-02 Akim Demaille <akim@epita.fr>
11535 Create tests/local.at for Bison generic testing macros.
11537 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
11538 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
11540 * tests/calc.at (AT_CHECK_CALC): Adjust.
11541 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
11542 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
11543 * tests/local.at: here.
11544 (AT_COMPILE_CXX): Tags the tests using it as c++.
11545 Ignore the test if CXX is not functional.
11547 2003-03-01 Paul Eggert <eggert@twinsun.com>
11549 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
11550 not loc->end, since loc->end might contain garbage and this leads
11551 to undefined behavior on some platforms.
11552 (id_loc, token_start): Use (IF_LINTed) initial values that do not
11553 depend on *loc, so that the reader doesn't give the the false
11554 impression that *loc is initialized.
11555 (<INITIAL>"%%"): Do not bother setting code_start, since its value
11556 does not survive the return.
11558 2003-03-01 Akim Demaille <akim@epita.fr>
11560 * src/scan-gram.l (code_start): Always initialize it when entering
11561 into yylex, as SC_EPILOGUE is activated *before* the corresponding
11562 yylex invocation. An alternative would be making it static, but
11563 then it starts with the second %%'s beginning, instead of its end.
11565 2003-02-28 Paul Eggert <eggert@twinsun.com>
11567 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
11568 around a UnixWare 7.1.1 porting bug reported by John Hughes in
11569 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
11571 2003-02-26 Paul Eggert <eggert@twinsun.com>
11573 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
11574 Remove Sequent/Pyramid discussion (nobody uses them any more).
11575 Merge VMS and MS-DOS discussion; these ports may well be dead
11576 but let's keep mentioning them for now. Put <> around email
11577 addresses. Add copyright notice.
11579 2003-02-24 Paul Eggert <eggert@twinsun.com>
11581 * data/glr.c (yy_reduce_print): yylineno -> yylno,
11582 to avoid collision with flex use of yylineno.
11583 Problem reported by Bruce Lilly in
11584 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
11585 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
11586 * data/yacc.c (yy_reduce_print): Likewise.
11588 * config/depcomp: Sync with Automake 1.7.3.
11590 2003-02-21 Akim Demaille <akim@epita.fr>
11592 * data/lalr1.cc: Use temporary variables instead of casts to
11593 change integer types.
11594 Suggested by Paul Eggert.
11596 2003-02-21 Akim Demaille <akim@epita.fr>
11598 * doc/bison.texinfo: Use "location" consistently to refer to @n,
11599 to avoid confusions with lalr1.cc's notion of Position.
11600 Suggested by Paul Eggert.
11602 2003-02-20 Akim Demaille <akim@epita.fr>
11604 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
11605 before initial_columns.
11606 (location.hh): Use consistent variable names when defining the
11608 Use "last" so that we subtract from Positions, not from unsigned.
11610 2003-02-20 Akim Demaille <akim@epita.fr>
11612 * data/lalr1.cc (position.hh): New subfile, including the extended
11613 and Doxygen'ed documentation of class Position.
11614 (location.hh): Use it.
11615 Document a` la Doxygen.
11616 With the help of Benoit Perrot.
11618 2003-02-20 Akim Demaille <akim@epita.fr>
11620 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
11622 Redefine AT_YYERROR_SEES_LOC_IF using it.
11623 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
11625 Don't use the location in yy::Parser::error_ and
11626 yy::Parser::print_ when not %locations.
11627 Activate more lalr1.cc tests.
11629 2003-02-19 Akim Demaille <akim@epita.fr>
11631 * data/lalr1.cc: When displaying a line number, be sure to make it
11634 2003-02-19 Akim Demaille <akim@epita.fr>
11636 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
11638 (YYABORT, YYACCEPT, YYERROR): New.
11639 * tests/calc.at: Renable the lalr1.cc test.
11641 2003-02-19 Akim Demaille <akim@epita.fr>
11643 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
11644 error recovery, mixing with/without pops and discarding of the
11647 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
11649 2003-02-17 Paul Eggert <eggert@twinsun.com>
11651 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
11652 * tests/testsuite.at (AT_COMPILE): Use them.
11653 This fixes the testsuite problem reported by Robert Lentz in
11654 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
11656 2003-02-12 Paul Eggert <eggert@twinsun.com>
11658 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
11659 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
11660 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
11661 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
11662 Check for malloc failure, for consistency with yacc.c.
11663 (yytname_size): Remove, for consistency with yacc.c.
11665 The bug still remains in data/lalr1.cc, as I didn't have time
11668 2003-02-06 Akim Demaille <akim@epita.fr>
11670 * configure.ac (GXX): Rename as...
11671 (CXX): this, to keep the original Autoconf semantics.
11673 * data/lalr1.cc: Fix b4_copyright invocations.
11674 If YYDEBUG is not defined, don't depend upon name_ being defined.
11675 (location.hh): Include string and iostream.
11676 (Position::filename): New member.
11677 (Position::Position ()): New.
11678 (operator<< (Position)): New.
11679 (operator- (Position, int)): New.
11680 (Location::first, Location::last): Rename as...
11681 (Location::begin, Location::end): these, to mock the conventional
11683 (operator<< (Location)): New.
11684 * tests/atlocal.in (CXX): New.
11685 * tests/testsuite.at (AT_COMPILE_CXX): New.
11686 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
11687 locations in a more synthetic way.
11688 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
11690 Adjust the C locations to match those from Emacs: first column is
11692 Change all the expected results.
11693 Conform to the GCS: simplify the locations when applicable.
11694 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
11695 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
11696 these CPP macros with the m4 macros new defined by...
11697 (AT_CHECK_PUSHDEFS): this, i.e.:
11698 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
11699 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
11701 (AT_CHECK_POPDEFS): Undefine them.
11702 (AT_CHECK_CALC_LALR1_CC): New.
11703 Use it for the first lalr1.cc test.
11705 2003-02-04 Akim Demaille <akim@epita.fr>
11707 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
11708 Location as is defined.
11710 2003-02-04 Akim Demaille <akim@epita.fr>
11712 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
11713 name_ being defined.
11715 2003-02-03 Paul Eggert <eggert@twinsun.com>
11717 * src/gram.h (start_symbol): Remove unused decl.
11719 Use more-consistent naming conventions for local vars.
11721 * src/derives.c (derives_compute): Change type of local var from
11722 int to rule_number.
11723 * src/gram.c (grammar_rules_partial_print): Likewise.
11724 * src/print.c (print_core): Likewise.
11725 * src/reduce.c (reduce_grammar_tables): Likewise.
11727 * src/gram.c (grammar_dump): Change name of item_number *
11728 local var from r to rp.
11729 * src/nullable.c (nullable_compute): Likewise.
11731 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
11733 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
11734 for symbol or symbol_number var.
11735 * src/reader.c (grammar_start_symbol_set): Likewise.
11736 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
11738 * src/state.c (transitions_to): Likewise.
11739 * src/state.h: Likewise.
11740 * src/tables.c (symbol_number_to_vector_number): Likewise.
11742 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
11745 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
11748 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
11751 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
11752 Use str, not s, for char * var. Use ch, not c, for character var.
11753 Use size for size var.
11755 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
11757 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
11759 * src/uniqstr.h: Likewise.
11761 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
11762 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
11763 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
11764 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
11765 param to have same name as that of enum, so that we don't use
11766 "s" to stand for a non-state.
11768 2003-02-02 Akim Demaille <akim@epita.fr>
11770 * src/scan-skel.l: Scan more than one inert character per yylex
11773 2003-02-01 Paul Eggert <eggert@twinsun.com>
11777 * po/LINGUAS: Add ms.
11779 2003-01-30 Akim Demaille <akim@epita.fr>
11781 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
11783 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11785 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
11788 Changes in response to error report by S. Eken: GLR mode does not
11789 handle negative $ indices or $ indices in embedded rules correctly.
11790 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
11792 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
11793 (b4_rhs_location): Ditto.
11794 (yyfill): New function to copy from stack tree into array
11796 (yyuserAction): Modify to allow incremental move of semantic values
11797 to rhs array when in GLR mode.
11798 Define YYFILL to use in user-defined actions to fill semantic array
11800 Remove dummy use of yystack, as there is now a guaranteed use.
11801 (yydoAction): Modify to allow incremental move of semantic values
11802 to rhs array when in GLR mode.
11803 (yyresolveAction): Ditto.
11804 (yyglrShiftDefer): Update comment.
11805 (yyresolveStates): Use X == NULL for pointers, not !X.
11806 (yyglrReduce): Ditto.
11807 (yydoAction): Ditto
11809 * tests/glr-regr1.at: Rename to ...
11810 * tests/glr-regression.at: Add new regression test for the problems
11811 described above (adapted from S. Eken).
11812 Update copyright notice.
11813 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
11814 * tests/Makefile.am: Ditto.
11816 2003-01-28 Paul Eggert <eggert@twinsun.com>
11818 * data/lalr1.cc: Do not use @output_header_name@ unless
11819 b4_defines_flag is set. This fixes two bugs reported by
11821 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
11822 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
11824 2003-01-21 Paul Eggert <eggert@twinsun.com>
11826 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
11827 we don't need to worry about yyerrlab1 being reported as an
11828 "unused label" by non-GCC C compilers. The downside is that if
11829 locations are used then a couple of statements are duplicated each
11830 time YYERROR is invoked, but the upside is that the warnings
11832 (yyerrlab1): Move code to YERROR.
11833 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11834 This reverts some of the 2002-12-27 change.
11836 2003-01-17 Paul Eggert <eggert@twinsun.com>
11838 * src/output.c (symbol_printers_output): Fix typo that led
11839 to core dump. Problem reported by Antonio Rus in
11840 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
11842 2003-01-13 Akim Demaille <akim@epita.fr>,
11843 Quoc Peyrot <chojin@lrde.epita.fr>,
11844 Robert Anisko <anisko_r@lrde.epita.fr>
11846 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
11847 when the stacks contain one element, as the loop would otherwise
11848 free the last state, and then use the top state (the one we just
11849 popped). This means that the initial elements will not be freed
11850 explicitly, as is the case in yacc.c; it is not a problem, as
11851 these elements have fake values.
11853 2003-01-11 Paul Eggert <eggert@twinsun.com>
11855 * NEWS: %expect-violations are now just warnings, reverting
11856 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
11857 bootstrapping problem reported by Matthias Klose; see
11858 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
11859 * src/conflicts.c (conflicts_print): Likewise.
11860 * tests/conflicts.at (%expect not enough, %expect too much,
11861 %expect with reduce conflicts): Likewise.
11862 * doc/bison.texinfo (Expect Decl): Document this. Also mention
11863 that the warning is enabled if the number of conflicts changes
11864 (not necessarily increases).
11866 * src/getargs.c (version): Update copyright year.
11868 2003-01-09 Akim Demaille <akim@epita.fr>
11870 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
11872 2003-01-08 Paul Eggert <eggert@twinsun.com>
11874 * Makefile.maint (WGETFLAGS):
11875 New macro, containing "-C off" to disable proxy caches.
11876 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
11877 (rel-check): Use $(WGET) instead of wget.
11879 2003-01-06 Paul Eggert <eggert@twinsun.com>
11881 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
11882 the GLR paper of Scott, Johnstone and Hussain.
11884 2003-01-04 Paul Eggert <eggert@twinsun.com>
11886 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
11887 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
11888 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
11889 (EXTRA_LIBRARIES): New var, for liby.a.
11890 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
11891 (EXTRA_SCRIPTS): New var, for yacc.
11893 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
11894 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
11895 Problem reported by Nelson H. F. Beebe.
11897 2003-01-03 Paul Eggert <eggert@twinsun.com>
11899 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
11900 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
11901 when compiling Bison 1.875's `bitset bset = obstack_alloc
11902 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
11904 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
11905 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
11906 grow to a huge size with typical invocation.
11908 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
11909 Use the pattern recommended by Autoconf 2.57, except also protect
11910 against double-definition.
11911 * src/system.h: Likewise.
11912 Portability issues reported by Nelson H. F. Beebe.
11914 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
11915 All uses changed. Provide a definition in both C and C++.
11916 (yytrue, yyfalse): Define even if defined (__cplusplus).
11918 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
11919 Reported by Nelson H. F. Beebe.
11921 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
11923 2003-01-02 Paul Eggert <eggert@twinsun.com>
11925 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
11926 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
11927 Bug reported by Nelson H. F. Beebe.
11929 2003-01-01 Paul Eggert <eggert@twinsun.com>
11933 2002-12-30 Paul Eggert <eggert@twinsun.com>
11935 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
11937 (<INITIAL>","): Here. This causes stray "," to be treated
11940 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
11941 last brace in braced code when not in Yacc mode, for compatibility
11942 with Bison 1.35. This resurrects the 2001-12-15 patch to
11945 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
11946 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
11948 2002-12-28 Paul Eggert <eggert@twinsun.com>
11950 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
11951 that of SYM's type. This fixes Debian bug 168069, reported by
11954 2002-12-28 Paul Eggert <eggert@twinsun.com>
11958 Switch back to the Yacc style of conflict reports, undoing some
11959 of the 2002-07-30 change.
11960 * doc/bison.texinfo (Understanding): Use Yacc style for
11961 conflict reports. Also, use new way of locating rules.
11962 * src/conflicts.c (conflict_report):
11963 Renamed from conflict_report_yacc, removing the old
11964 'conflict_report'. Translate the entire conflict report at once,
11965 so that we don't assume that "," has the same interpretation in
11967 (conflicts_output): Use Yacc-style conflict report for each state,
11968 instead of our more-complicated style.
11969 (conflicts_print): Use Yacc-style conflict report, except print
11970 the input file name when not emulating Yacc.
11971 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11972 Conflicted Reduction, %expect not enough, %expect too much,
11973 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
11974 * tests/existing.at (GNU Cim Grammar): Likewise.
11975 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
11977 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
11978 fatal): Don't invoke fflush; it's not needed and it might even be
11979 harmful for stdout, as stdout might not be open.
11980 * src/reduce.c (reduce_print): Likewise.
11982 2002-12-27 Paul Eggert <eggert@twinsun.com>
11984 Fix a bug where error locations were not being recorded correctly.
11985 This problem was originally reported by Paul Hilfinger in
11986 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
11988 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11989 top of the location stack's error locations.
11990 (yyerrlab): Set it. When discarding a token, push its location
11991 onto yylerrsp so that we don't lose track of the error's end.
11992 (yyerrlab1): Now is only the target of YYERROR, so that we can
11993 properly record the location of the action that failed. For GCC
11994 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11995 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11996 (yyerrlab2): New label, which yyerrlab now falls through to.
11997 Compute the error's location by applying YYLLOC_DEFAULT to
11998 the locations of all the symbols that went into the error.
11999 * doc/bison.texinfo (Location Default Action): Mention that
12000 YYLLOC_DEFAULT is also invoked for syntax errors.
12001 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12002 Error locations include the locations of all the tokens that were
12003 discarded, not just the last token.
12005 2002-12-26 Paul Eggert <eggert@twinsun.com>
12007 * src/files.c: Include quote.h.
12008 (compute_output_file_names): Warn if we detect conflicting
12009 outputs to the same file. This should catch the misunderstanding
12010 exemplified by Debian Bug 165349, reported by Bruce Stephens..
12012 * src/conflicts.c (conflicts_print): If the user specifies
12013 "%expect N", report an error if there are any reduce/reduce
12014 conflicts. This is what the manual says should happen.
12015 This fixes Debian bug 130890, reported by Anthony DeRobertis.
12016 * tests/conflicts.at (%expect with reduce conflicts): New test.
12018 Don't use m4_include on relative file names, as it doesn't work as
12019 desired if there happens to be a file with that name under ".".
12021 * m4sugar/version.m4: Remove; it was included but it wasn't used.
12022 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
12023 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
12024 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
12025 * src/output.c (output_skeleton): Use full path names when
12026 specifying a file to include; don't rely on include path, as
12027 it's unreliable when the working file contains a file with
12030 2002-12-25 Paul Eggert <eggert@twinsun.com>
12032 Remove obsolete references to bison.simple and bison.hairy.
12033 Problem mentioned by Aubin Mahe in
12034 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
12035 * data/glr.c: Comment fix.
12036 * doc/bison.1: Remove references. Also, mention "yacc".
12038 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
12041 * src/parse-gram.y (declaration): Use enum "report_states" rather
12042 than its numeric value 1.
12044 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
12045 opening a new one. This fixes Debian bug 165349, reported by
12048 2002-12-24 Paul Eggert <eggert@twinsun.com>
12052 * Makefile.maint (cvs-update): Don't assume that the shell
12053 supports $(...), as Solaris sh doesn't.
12055 * src/parse-gram.y (lloc_default): Remove test for empty
12056 nonterminals at the end, since it didn't change the result.
12058 2002-12-24 Paul Eggert <eggert@twinsun.com>
12060 If the user does not define YYSTYPE as a macro, Bison now declares it
12061 using typedef instead of defining it as a macro. POSIX requires this.
12062 For consistency, YYLTYPE is also declared instead of defined.
12064 %union directives can now have a tag before the `{', e.g., the
12065 directive `%union foo {...}' now generates the C code
12066 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12067 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12068 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12069 instead of `yyltype'.
12071 `yystype' and `yyltype' are now obsolescent macros instead of being
12072 typedefs or tags; they are no longer documented and will be
12073 withdrawn in a future release.
12075 * data/glr.c (b4_location_type): Remove.
12076 (YYSTYPE): Renamed from yystype.
12077 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
12078 (struct YYLTYPE): Renamed from struct yyltype.
12079 (YYLTYPE): Renamed from yyltype.
12080 (yyltype, yystype): New (and obsolescent) macros,
12081 for backward compatibility.
12082 * data/yacc.c: Likewise.
12084 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12085 does not specify a union tag. This is for compatibility with
12088 * src/parse-gram.y (add_param): 2nd arg is now char * not char
12089 const *, since it is now modified by stripping surrounding { }.
12090 (current_braced_code): Remove.
12091 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
12092 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
12093 trailing " {...}". Now of type <chars>.
12094 (grammar_declaration): Adjust to bundled tokens.
12095 (code_content): Remove; stripping is now done by add_param.
12096 (print_token_value): Print contents of bundled tokens.
12097 (token_name): New function.
12099 * src/reader.h (braced_code, current_braced_code): Remove.
12100 (token_name): New decl.
12102 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
12103 token_type, not braced_code code_kind. All uses changed.
12104 (SC_PRE_CODE): New state, for scanning after a keyword that
12105 has (or usually has) an immediately-following braced code.
12106 (token_type): New local var, to keep track of which token type
12107 to return when scanning braced code.
12108 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
12109 <INITIAL>"%parse-param", <INITIAL>"%printer",
12110 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
12111 instead of returning a token type immediately.
12112 (<INITIAL>"{"): Set token type.
12113 (<SC_BRACED_CODE>"}"): Use it.
12114 (handle_action_dollar, handle_action_at): Now returns bool
12115 indicating success. Fail if ! current_rule; this prevents a core dump.
12116 (handle_symbol_code_dollar, handle_symbol_code_at):
12117 Remove; merge body into caller.
12118 (handle_dollar, handle_at): Complain in invalid contexts.
12120 * NEWS, doc/bison.texinfo: Document the above.
12121 * NEWS: Fix years and program names in copyright notice.
12123 2002-12-17 Paul Eggert <eggert@twinsun.com>
12125 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
12126 Reporting, Table of Symbols): Omit mentions of %lex-param and
12127 %parse-param from the documentation for now.
12129 2002-12-15 Paul Eggert <eggert@twinsun.com>
12131 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
12132 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
12133 lookahead symbol, and which sets yychar in parser actions) and it
12134 disagreed with the Bison documentation. Bug
12135 reported by Andrew Walrond.
12137 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12138 as the caller now does that.
12139 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12140 (YYEMPTY): Parenthesize right hand side, since others use it.
12141 (yyparse): Don't assume that our generated code is the only code
12144 2002-12-13 Paul Eggert <eggert@twinsun.com>
12148 POSIX requires a "yacc" command.
12149 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
12150 (MOSTLYCLEANFILES): Add yacc.
12152 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
12153 as an alias for bison y.
12155 * po/LINGUAS: Add da.
12157 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
12158 problem with latest <getopt.h>.
12159 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
12161 * doc/fdl.texi: Upgrade to 1.2.
12162 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
12163 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
12164 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
12166 * config/install-sh: Sync with autotools.
12168 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
12169 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12170 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
12171 locations are requested.
12172 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
12173 locations are requested.
12175 2002-12-12 Paul Eggert <eggert@twinsun.com>
12177 Remove unportable casts and storage allocation tricks.
12178 While we're at it, remove almost all casts, since they
12179 usually aren't needed and are a sign of trouble.
12181 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12183 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12184 the pointer DSET returned by malloc; this isn't portable.
12185 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12186 Similarly for DERIVES.
12187 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12188 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
12189 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
12191 * src/derives.c (derives_compute): Do not bother invoking

12195 rather than XMALLOC (char, N).
12197 * src/files.c (filename_split): Rewrite to avoid cast.
12199 * src/gram.h (symbol_number_as_item_number,
12200 item_number_as_symbol_number, rule_number_as_item_number,
12201 item_number_as_rule_number):
12202 Now inline functions rather than macros, to avoid casts.
12203 * src/state.h (state_number_as_int): Likewise.

12205 symbol_number_to_vector_number): Likewise.
12207 * src/gram.h (int_of_rule_number): Remove; no longer used.
12209 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,

12212 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12215 * src/muscle_tab.c (muscle_m4_output):
12216 Now inline. Return bool, not int.
12217 * src/state.c (state_compare): Likewise.
12218 * src/symtab.c (symbol_check_defined,
12219 symbol_check_alias_consistency, symbol_pack, symbol_translation,

12227 symbol_check_alias_consistency_processor, symbol_pack_processor,
12228 symbol_translation_processor, hash_symbol_comparator,
12229 hash_symbol_hasher): Likewise.
12230 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12231 * src/muscle_tab.c (muscles_m4_output):
12232 Use new functions instead of casting old functions unportably.
12233 * src/state.c (state_hash_new): Likewise.
12234 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12235 symbols_token_translations_init):
12237 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12239 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12240 var instead of casting to long, to avoid casts.
12241 (prepare_states): Use MALLOC rather than alloca, so that we don't
12242 have to worry about alloca.
12243 * src/state.c (state_hash_lookup): Likewise.
12245 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12246 local var instead of casting to unsigned char, to avoid casts.
12248 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12249 STATE_ALLOC): Remove.
12250 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12251 rather than calloc, and use offsetof to avoid allocating slightly
12253 (state_new): Initialize all members.
12255 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12257 * src/symtab.c (symbol_free): Remove; unused.
12258 (symbol_get): Remove cast in lhs of assignment.

12260 hashing-related ones.
12262 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12263 (symbol_processor): Remove.
12264 (symbols_do): Remove decl; now static.
12266 * src/system.h (alloca): Remove; decl no longer needed.
12267 (<stddef.h>): Include, for offsetof.
12268 (<inttypes.>, <stdint.h>): Include if available.
12269 (uintptr_t): New type, if system lacks it.
12270 (CALLOC, MALLOC, REALLOC): New macros.
12271 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these

12287 2002-12-09 Paul Eggert <eggert@twinsun.com>
12289 Change identifier spellings to avoid collisions with names
12290 that are reserved by POSIX.
12292 Don't use names ending in _t, since POSIX reserves them.
12293 For consistency, remove _e and _s endings -- they're weren't
12294 needed to remove ambiguity. All uses changed.
12295 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12296 turn was just renamed from struniq_t.
12297 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12298 which in turn was just renamed from struniq_processor_t.
12299 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

12370 value_t_as_yystype -> value_as_yystype.
12372 Don't include <errno.h> in the mainstream code, since it

12374 * lib/get-errno.c, lib/get-errno.h: New files.
12375 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

12389 Change all instances of "struniq" in names to "uniqstr", and
12390 likewise for "STRUNIQ" and "UNIQSTR".
12391 * src/uniqstr.c: Renamed from src/struniq.c.
12392 * src/uniqstr.h: Renamed from src/struniq.h.

12403 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
12404 (N_EXPAND): Renamed from N_STRETCH.
12406 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.

12428 for consistency with other names.
12429 * lib/timevar.h (timevar_report): New decl.
12430 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
12433 Sort include-file uses.
12435 Reorder all include files under src to be in the order "system.h".
12436 then the ../lib include files in angle brackets (alphabetized),
12437 then the . include files in double-quotes (alphabetized). Fix
12438 dependency breakages encountered in this process, as follows:
12439 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
12440 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
12441 * src/state.h: Include "symtab.h".
12443 2002-12-08 Paul Eggert <eggert@twinsun.com>
12445 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
12446 since this causes problems when __file__ contains character
12447 sequences like "@" that are treated specially by src/scan-skel.l.
12448 Instead, just use the file's basename. This fixes the bug
12449 reported by Martin Mokrejs in
12450 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
12452 2002-12-06 Paul Eggert <eggert@twinsun.com>
12454 Add support for rules that do not have trailing semicolons, as

12462 * src/location.h: Do not include <quotearg.h>; no longer needed.
12463 (boundary): New type.

12489 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
12491 (STEP): Remove. No longer needed, now that adjust_location does
12492 the work. All uses removed.
12493 (scanner_cursor): New var.
12494 (adjust_location): Renamed from extend_location. It now sets
12495 *loc and adjusts the scanner cursor. All uses changed.
12496 Don't bother testing for CR.
12497 (handle_syncline): Remove location arg; now updates scanner cursor.
12498 All callers changed.
12499 (unexpected_end_of_file): Now accepts start boundary of token or
12500 comment, not location. All callers changed. Update scanner cursor,
12502 (SC_AFTER_IDENTIFIER): New state.
12503 (context_state): Renamed from c_context. All uses changed.
12504 (id_loc, code_start, token_start): New local vars.
12505 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
12506 processing of Yacc white space and equivalents here.
12507 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
12508 instead of returning ID immediately, since we need to search for
12509 a subsequent colon.
12510 (<INITIAL>"'", "\""): Save token_start.
12511 (<INITIAL>"%{", "{", "%%"): Save code_start.
12512 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
12513 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
12514 BEGIN context_state at end, not INITIAL.
12515 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
12516 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
12517 Return correct token start.
12518 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
12519 the start of a character, string or multiline comment is found.
12520 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
12521 Reduction): Adjust reported locations to match the more-precise
12522 results now expected.
12523 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
12524 * tests/reduce.at (Useless Rules, Reduced Automaton,
12525 Underivable Rules): Likewise.
12526 * tests/regression.at (Invalid inputs): No longer `expecting ";"
12527 or "|"' now that so many other tokens are allowed by the new grammar.
12529 * src/complain.h (current_file): Remove duplicate decl;
12530 current_file is now owned by files.h.
12531 * src/complain.c, src/scan-gram.l: Include files.h.
12533 2002-12-06 Paul Eggert <eggert@twinsun.com>
12535 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
12536 promotes to int; it might be unsigned int.
12537 * data/yacc.c (yy_reduce_print): Likewise.
12539 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
12540 be #defined in the prologue, not in the Bison declarations.
12541 This fixes Debian Bug 102878, reported by Shaul Karl.
12543 2002-12-02 Paul Eggert <eggert@twinsun.com>
12545 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
12546 * lib/strtoul.c: New file, from gnulib.
12547 This fixes a porting bug reported by Peter Klein in
12548 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
12550 2002-11-30 Paul Eggert <eggert@twinsun.com>
12552 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
12553 and put only a forward declaration in the prologue. This is for
12554 consistency with the other scanner helper functions.
12556 Type clashes now generate warnings, not errors, since it
12557 appears that POSIX may allow some grammars with type clashes.
12558 * src/reader.c (grammar_current_rule_check): Warn about
12559 type clashes instead of complaining.
12560 * tests/input.at (Type Clashes): Expect warnings, not complaints.
12562 Add Yacc library, since POSIX requires it.
12563 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
12564 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
12565 * lib/main.c, lib/yyerror.c: New files.
12567 gram_error can be static; it need not be extern.
12568 * src/reader.h (gram_error): Remove decl.
12569 * src/parse-gram.y (gram_error): Now static. Add static decl.
12570 (print_token_value): Omit parameter names from forward decl,
12573 2002-11-29 Paul Eggert <eggert@twinsun.com>
12575 * doc/bison.texinfo: Emphasize that yylex and yyerror must
12576 be declared before being used. E.g., one should typically
12577 declare them in the prologue. Use GNU coding style in examples.
12578 Put "const" consistently after the type it modifies. Mention
12579 that C99 supports "inline". Mention that yyerror traditionally
12582 %parse-param and %lex-param now take just one argument, the
12583 declaration; the argument name is deduced from the declaration.
12585 * doc/bison.texinfo (Parser Function, Pure Calling, Error
12586 Reporting, Table of Symbols): Document this.
12587 * src/parse-gram.y (add_param): New function.
12589 (declaration): Implement new rule for %parse-param and %lex-param.
12590 * src/scan-gram.l: "," now elicits a warning, rather than being
12591 a token; this is more compatible with byacc.
12592 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
12594 2002-11-27 Paul Eggert <eggert@twinsun.com>
12596 Rename identifiers to avoid real and potential collisions.
12598 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
12599 to avoid collision with lex macro described by Bruce Lilly in
12600 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12601 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
12602 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
12603 * src/parse-gram.y (print_token_value): Renamed from yyprint.
12605 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
12606 The name "yycontrol" violates the name space rules, and this stuff
12607 wasn't being used anyway.
12608 (input): Remove action; this stuff wasn't being used.
12609 (gram_error): Rename local variable yylloc -> loc.
12610 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
12611 (YY_DECL): Don't use "yy" at start of local variables.
12612 All uses changed, e.g., yylloc -> loc.
12613 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
12614 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
12615 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
12616 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
12618 * src/parse-gram.y (gram_error): loc is now const *.
12619 * src/reader.h (gram_error): Likewise.
12621 2002-11-24 Paul Eggert <eggert@twinsun.com>
12625 * tests/actions.at (Actions after errors): Use an output format
12626 more similar to that of the Printers and Destructors test.
12627 Test the position of the ';' token too.
12628 (Printers and Destructors): Likewise.
12629 (Printers and Destructors: %glr-parser): Remove for now, to avoid
12630 unnecessarily alarming people when the test fails.
12632 * data/yacc.c (yyerrlab1): Move this label down, so that the
12633 parser does not discard the lookahead token if the user code
12634 invokes YYERROR. This change is required for POSIX conformance.
12636 * lib/error.c: Sync with gnulib.
12638 2002-11-22 Paul Eggert <eggert@twinsun.com>
12640 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
12641 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
12642 * lib/xmalloc.c: Likewise.
12644 2002-11-20 Paul Eggert <eggert@twinsun.com>
12646 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
12648 2002-11-20 Paul Eggert <eggert@twinsun.com>
12650 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
12651 should use `if (! x) abort ();' rather than `assert (x);', and
12652 anyway it's one less thing to worry about configuring.
12654 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
12655 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
12656 and replace all instances of assert with abort.
12657 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
12658 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
12660 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
12661 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
12662 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
12663 hash_find_entry, hash_rehash, hash_insert): Likewise.
12664 * src/conflicts.c (resolve_sr_conflict): Likewise.
12665 * src/lalr.c (set_goto_map, map_goto): Likewise.
12666 * src/nullable.c (nullable_compute): Likewise.
12667 * src/output.c (prepare_rules, token_definitions_output): Likewise.
12668 * src/reader.c (packgram, reader): Likewise.
12669 * src/state.c (state_new, state_free, state_transitions_set,
12670 state_reduction_find): Likewise.
12671 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
12672 symbol_pack): Likewise.
12673 * src/tables.c (conflict_row, pack_vector): Likewise.
12674 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12675 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12676 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
12677 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
12679 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
12680 (ARGMATCH_CONSTRAINT): New macro.
12681 (ARGMATCH_ASSERT): Use it.
12683 * src/system.h (verify): New macro.
12684 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
12685 rather than assert.
12686 * src/tables.c (tables_generate): Likewise.
12688 * src/struniq.c (struniq_assert): Now returns void, and aborts
12689 if the assertion is false.
12690 (struniq_assert_p): Remove.
12691 * src/struniq.h: Likewise.
12693 2002-11-18 Paul Eggert <eggert@twinsun.com>
12695 * data/glr.c (yygetLRActions): Replace `yyindex' with
12696 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
12697 This fixes the regression with Sun ONE Studio 7 cc that I reported in
12698 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
12700 2002-11-18 Akim Demaille <akim@epita.fr>
12702 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
12704 From Tim Van Holder.
12706 2002-11-17 Paul Eggert <eggert@twinsun.com>
12708 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
12709 to "SyntaxError" for consistency with my 2002-11-15 change.
12711 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
12712 not define to {}, since this breaks the common use of `YYDPRINTF
12713 ((...));' if a single statement is desired (e.g. before `else').
12714 Work around GCC warnings by surrounding corresponding calls with
12716 (yyhasResolvedValue): Remove unused function.
12717 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
12719 (yyreportSyntaxError): Renamed from yyreportParseError.
12720 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
12722 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
12723 extern when possible. Remove unused initializations.
12725 2002-11-16 Akim Demaille <akim@epita.fr>
12727 Augment the similarity between GLR and LALR traces.
12729 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
12730 (YY_REDUCE_PRINT): New.
12731 (yyparse): Use them.
12732 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
12734 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
12735 state reached after the reduction/recovery, since...
12736 (yyparse, yyprocessOneStack): Report the state we are entering in.
12738 2002-11-16 Akim Demaille <akim@epita.fr>
12740 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
12741 Add support for --trace=skeleton.
12742 * src/scan-skel.l: %option debug.
12743 Scan strings of non-@ or \n instead of character by character.
12744 (scan_skel): Handle trace_skeleton.
12746 (@output_parser_name@, @output_header_name@): ``Restore'' their
12747 support (used to be M4 macros).
12748 * data/yacc.c: Quote larger chunks, a la glr.c.
12749 * data/lalr1.cc: Likewise.
12750 The header guards are no longer available, so use some other
12751 string than `YYLSP_NEEDED'.
12753 2002-11-16 Akim Demaille <akim@epita.fr>
12755 Make the ``Printers and Destructors'' test more verbose, taking
12756 `yacc.c''s behavior as (possibly wrong) reference.
12758 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
12759 instead of fprint on stdout.
12760 Set and report the last_line of the symbols.
12761 Consistently display values and locations.
12763 2002-11-16 Paul Eggert <eggert@twinsun.com>
12765 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
12767 2002-11-15 Paul Eggert <eggert@twinsun.com>
12769 * tests/actions.at (Actions after errors): New test case.
12771 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
12772 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
12773 tests/action.at, tests/calc.at, tests/conflicts.at,
12774 tests/cxx-type.at, tests/regression.at:
12775 "parse error" -> "syntax error" for POSIX compatibility.
12776 "parsing stack overflow..." -> "parser stack overflow" so
12777 that code matches Bison documentation.
12779 2002-11-15 Akim Demaille <akim@epita.fr>
12781 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
12782 take two BRACED_CODE, not two string_content.
12783 Free the scanner's obstack when we are done.
12784 (code_content): New.
12785 * tests/calc.at: Adjust.
12786 * doc/bison.texinfo: Adjust.
12787 Also, make sure to include the `,' for these declarations.
12789 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
12791 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
12792 definition; avoids potential autoreconf problems.
12794 2002-11-15 Akim Demaille <akim@epita.fr>
12796 Always check the value returned by yyparse.
12798 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
12799 returned by yyparse.
12800 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
12802 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
12803 returned by yyparse.
12805 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12807 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
12810 2002-11-14 Paul Eggert <eggert@twinsun.com>
12812 * src/output.c (output_skeleton): Call xfopen instead of
12813 duplicating xfopen's body.
12815 Fix bugs reported by Nelson H. F. Beebe in
12816 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
12818 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
12819 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
12820 Group compiler. Instead, use "$CC -E bar.c". Include the .h
12821 file twice in the grammar, as an extra check.
12823 * tests/input.at (Torturing the Scanner): Surround the
12824 backslash-newline tests with "#if 0", to make it less likely that
12825 we'll run into compiler bugs. Bring back solitary \ inside
12826 comment, but add a closing comment to work around HP C bug. Don't
12827 test backslash-newline in C character constant.
12829 2002-11-14 Akim Demaille <akim@epita.fr>
12831 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
12832 status of the compiler.
12833 Calling `exit 1' is no longer needed.
12834 Reported by Nelson H. F. Beebe.
12836 2002-11-14 Akim Demaille <akim@epita.fr>
12838 * tests/atlocal.in (CPPFLAGS): We have config.h.
12839 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
12841 * tests/actions.at, tests/calc.at, tests/conflicts.at,
12842 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
12843 * tests/regression.at, tests/torture.at: Use them for all the
12844 grammars that are to be compiled.
12845 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
12846 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
12847 * doc/bison.texinfo (GLR Parsers): Document `inline'.
12849 2002-11-14 Akim Demaille <akim@epita.fr>
12851 * doc/bison.texinfo: Various formatting changes (alignments in
12852 samples, additional @group/@end group, GCS in samples.
12853 Use @deffn instead of simple @table to define the directives,
12854 macros, variables etc.
12856 2002-11-13 Paul Eggert <eggert@twinsun.com>
12858 Fix some bugs reported by Albert Chin-A-Young in
12859 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
12861 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
12862 -o c"; the HP C compiler chatters during compilation.
12863 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
12864 * tests/headers.at (export YYLTYPE): Likewise.
12866 * tests/input.at (Torturing the Scanner): Remove lines containing
12867 solitary backslashes, as they tickle a bug in the HP C compiler.
12869 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
12870 comments, since they're not portable. Use GNU coding style.
12872 2002-11-13 Akim Demaille <akim@epita.fr>
12874 * data/yacc.c: Leave bigger chunks of quoted text.
12875 (YYDSYMPRINTF): New.
12876 Use it to report symbol activities.
12877 * data/glr.c (YYDSYMPRINTF): New.
12880 2002-11-12 Paul Eggert <eggert@twinsun.com>
12884 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
12885 (yyglrReduce): Return yyok, not 0.
12886 This should avoid the enumerated-type warnings reported
12887 by Nelson H. F. Beebe in
12888 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
12890 * lib/bbitset.h (BITSET_INLINE): Remove.
12891 * lib/bitset.h [! BITSET_INLINE]: Remove.
12892 (bitset_set, bitset_reset, bitset_test): Rename local vars
12893 to avoid shadowing warnings by GCC.
12895 * data/glr.c (inline): Remove #define. It's the user's
12896 responsibility to #define it away, just like 'const'.
12897 This fixes one of the bugs reported by Nelson H. F. Beebe in
12898 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
12900 * Makefile.maint (po-check): Scan .l and .y files instead of the
12901 .c and the .h files that they generate. This fixes the bug
12902 reported by Tim Van Holder in:
12903 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
12904 Look for N_ as well as for _. Try to avoid matching #define for
12906 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
12907 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
12908 * src/scan-gram.l: Revamp regular expressions so that " and '
12909 do not confuse xgettext.
12911 * src/struniq.h (struniq_new): Do not declare the return type
12912 to be 'const'; this violates the C standard.
12913 * src/struniq.c (struniq_new): Likewise.
12915 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
12917 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
12918 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
12921 2002-11-12 Akim Demaille <akim@epita.fr>
12923 * Makefile.maint: Sync with Autoconf:
12924 (local_updates): New.
12926 2002-11-12 Akim Demaille <akim@epita.fr>
12928 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
12930 2002-11-12 Akim Demaille <akim@epita.fr>
12932 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
12935 2002-11-12 Akim Demaille <akim@epita.fr>
12937 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
12940 2002-11-12 Akim Demaille <akim@epita.fr>
12942 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.

13061 Revamp to fix many (but not all) of the C- and M4-related quoting
13062 problems. Among other things, this fixes the Bison bug reported
13063 by Jan Hubicka when processing the Bash grammar; see:
13064 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
13066 Use new @ escapes consistently. Represent brackets with @{ and @}
13067 rather than @<:@ and @:>@, since this works a bit better with dumb
13068 editors like vi. Represent @ with @@, since @ is now consistently
13069 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13070 __ofile__, to avoid unexpected expansions. Similarly, use @output
13071 rather than #output.
13073 * data/c.m4 (b4_copyright): Omit file name from comment, since
13074 the file name could contain "*/".
13075 (b4_synclines_flag): Don't quote the 2nd argument; it should already
13076 be quoted. All uses changed.
13078 * data/glr.c: Use new @ escapes consistently.
13079 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
13080 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
13081 Remove, since they couldn't handle arbitrary characters in file
13083 * data/lalr1.cc: Likewise.
13084 * data/yacc.c: Likewise.
13086 * src/files.c (output_infix): Remove; all uses removed.
13087 * src/files.h: Likewise.
13089 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
13090 mishandled funny characters in file names, and anyway it isn't
13092 * data/yacc.c: Likewise.
13093 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
13095 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
13096 * data/yacc.c: Likewise.
13098 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
13100 (muscle_init): Quote filename as a C string.
13101 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
13102 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
13103 * src/output.c (escaped_file_name_output): New function.
13104 (prepare_symbols): Quote tokens for M4.
13105 (prepare): Don't insert output_infix, output_prefix,
13106 output_parser_name, output_header_name; this is now down by scan-skel.
13107 Insert skeleton as a C string.
13109 * src/output.c (user_actions_output, symbol_destructors_output,
13110 symbol_printers_output): Quote filenames for C and M4.
13111 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13113 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
13114 escapes other than \\ and \'; this simplifies the code.
13115 (<SC_STRING>): Likewise, for \\ and \".
13116 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13117 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13118 Use new escapes @{ and @} for [ and ].
13120 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13121 them with auto vars.
13122 Switch to new escape scheme, where @ is the escape character uniformly.
13123 Abort if a stray escape character is found. Avoid unbounded input
13124 buffer when parsing non-escaped text.
13126 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
13127 __oline__, #output, $@, and @{ do not have unintended meanings.
13129 2002-11-09 Paul Eggert <eggert@twinsun.com>
13131 Fix the test failure due to GCC warnings described in
13132 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
13133 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
13134 evaluate to 0 if it's impossible for NINF to be in the respective
13136 (yygetLRActions, yyrecoverParseError): Use them.
13138 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13139 counted in the token inserted at end of file. Now takes
13140 location_t *, not location_t, so that the location can be
13141 adjusted. All uses changed.
13143 * tests/regression.at (Invalid inputs): Adjust wording in
13144 diagnostic to match the new behavior.
13146 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13147 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13148 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13149 abort ();'. This reduces the runtime of the "Many lookaheads"
13150 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13153 2002-11-07 Paul Eggert <eggert@twinsun.com>
13155 * src/parse-gram.y (CHARACTER): Remove unused token.
13158 * src/scan-gram.l: Remove stack option. We no longer use the
13159 stack, since the stack was never deeper than 1; instead, use the
13160 new auto var c_context to record the stacked value.
13162 Remove nounput option. At an unexpected end of file, we now unput
13163 the minimal input necessary to end cleanly; this simplifies the
13166 Avoid unbounded token sizes where this is easy.
13168 (unexpected_end_of_file): New function.
13169 Use it to systematize the error message on unexpected EOF.
13170 (last-string): Now auto, not static.

13174 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
13175 not the (never otherwised-used) CHARACTER.
13177 2002-11-07 Akim Demaille <akim@epita.fr>

13407 * src/files.h (xfclose): Return void, not int, since it always
13409 * src/files.c (xfclose): Likewise. Report I/O error if ferror
13411 * src/output.c (output_skeleton): Use xfclose rather than fclose
13412 and ferror. xfclose now checks ferror.
13414 * data/glr.c (YYLEFTMOST_STATE): Remove.
13415 (yyreportTree): Use a stack-based leftmost state. This avoids
13416 our continuing battles with bogus warnings about initializers.
13418 2002-10-30 Akim Demaille <akim@epita.fr>
13420 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
13423 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13425 * tests/glr-regr1.at: New test for reported regressions.
13426 * tests/testsuite.at: Add glr-regr1.at test.
13427 * tests/Makefile.am: Add glr-regr1.at test.
13429 2002-10-24 Paul Eggert <eggert@twinsun.com>
13433 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
13434 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
13435 we use malloc. Don't assume 'A' through 'Z' are contiguous.
13436 Don't assume strdup exists; POSIX says its an XSI extension.
13437 Check for buffer overflow on input.
13439 2002-10-24 Akim Demaille <akim@epita.fr>
13441 * src/output.c (output_skeleton): Don't disable M4sugar comments
13442 too soon: it results in comments being expanded.
13443 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
13446 2002-10-24 Akim Demaille <akim@epita.fr>
13448 * data/yacc.c (m4_int_type): New.
13449 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
13450 char' as only yacc.c wants K&R portability.
13451 * data/glr.c (yysigned_char): Remove.
13452 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
13453 Reported by Quoc Peyrot.
13455 2002-10-23 Paul Eggert <eggert@twinsun.com>
13457 * src/main.c (main): With --trace=time, report times even if a
13458 non-fatal error occurs. Formerly, the times were reported in some
13459 such cases but not in others.
13460 * src/reader.c (reader): Just return if a complaint has been issued,
13461 instead of exiting, so that 'main' can report times.
13463 2002-10-22 Akim Demaille <akim@epita.fr>
13465 * src/system.h: Include sys/types.
13466 Reported by Bert Deknuydt.
13468 2002-10-23 Paul Eggert <eggert@twinsun.com>
13470 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
13471 Suggested by Art Haas.
13473 2002-10-22 Paul Eggert <eggert@twinsun.com>
13475 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
13476 decl; not needed any more.
13477 * src/main.c (main): Use return to exit, undoing yesterday's change.
13478 The last OS that we could find where this wouldn't work is
13479 SunOS 3.5, and that's too old to worry about now.
13481 * data/glr.c (struct yyltype): Define members even when not
13482 doing locations. This is more consistent with yacc.c, and it
13483 works around the following bug reports:
13484 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
13485 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
13487 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
13488 @acronym consistently. Standardize on "Yacc" instead of "YACC",
13489 "Algol" instead of "ALGOL". Give a bit more history about BNF.
13491 2002-10-22 Akim Demaille <akim@epita.fr>
13493 * data/README: New.
13495 2002-10-21 Paul Eggert <eggert@twinsun.com>
13497 Be consistent about 'bool'; the old code used an enum in one
13498 module and an int in another, and this violates the C standard.
13499 * m4/stdbool.m4: New file, from coreutils 4.5.3.
13500 * configure.ac (AC_HEADER_STDBOOL): Add.
13501 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
13502 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
13503 * src/symtab.c (hash_compare_symbol_t): Likewise.
13504 * src/system.h (bool, false, true): Use a definition consistent
13505 with ../lib/hash.c. All uses changed.
13507 * src/complain.c (warning_issued): Renamed from warn_message_count,
13508 so that we needn't worry about integer overflow (!).
13509 Now of type bool. All uses changed.
13510 (complaint_issued): Renamed from complain_message_count; likewise.
13512 * src/main.c (main): Use exit to exit with failure.
13514 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
13515 rather than 1 and 0.
13516 * src/main.c (main): Likewise.
13517 * src/getargs.c (getargs): Likewise.
13518 * src/reader.c (reader): Likewise.
13520 * src/getarg.c (getargs): Remove duplicate code for
13521 "Try `bison --help'".
13523 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
13524 What was that "2" for?
13526 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
13527 * src/getargs.c (usage): Likewise.
13529 * src/getargs.c (getargs): When there are too few operands, report
13530 the last one. When there are too many, report the first extra
13531 one. This is how diffutils does it.
13533 2002-10-20 Paul Eggert <eggert@twinsun.com>
13535 Remove K&R vestiges.
13536 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
13537 * src/complain.c (VA_START): Remove. Assume prototypes.
13538 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
13539 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
13540 fatal): Assume prototypes.
13541 * src/complain.h: Assume prototypes.
13542 * src/system.h (PARAMS): Remove.
13543 Include <limits.h> unconditionally, since it's guaranteeed even
13544 for a freestanding C89 compiler.
13545 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
13546 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
13548 2002-10-20 Akim Demaille <akim@epita.fr>
13550 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
13551 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
13552 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
13553 (yyresolveStates, yyresolveAction, yyresolveStack)
13554 (yyprocessOneStack): Use them.
13555 (yy_reduce_print): New.
13556 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
13558 2002-10-20 Akim Demaille <akim@epita.fr>
13560 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
13561 arguments and output `void'.
13562 (b4_c_function): Rename as...
13563 (b4_c_function_def): this.
13564 (b4_c_function_decl, b4_c_ansi_function_def)
13565 (b4_c_ansi_function_decl): New.
13566 Change the interpretation of the arguments: before `int, foo', now
13568 * data/yacc.c (yyparse): Prototype and define thanks to these.
13569 Adjust b4_c_function_def uses.
13570 * data/glr.c (yyparse): Likewise, but ANSI only.
13572 2002-10-20 Akim Demaille <akim@epita.fr>
13574 * src/output.c (prepare): Move the definition of `tokens_number',
13575 `nterms_number', `undef_token_number', `user_token_number_max'
13577 (prepare_tokens): Here.
13578 (prepare_tokens): Rename as...
13579 (prepare_symbols): this.
13580 (prepare): Move the definition of `rules_number' to...
13581 (prepare_rules): here.
13582 (prepare): Move the definition of `last', `final_state_number',
13583 `states_number' to...
13584 (prepare_states): here.
13585 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
13587 2002-10-20 Akim Demaille <akim@epita.fr>
13589 * src/tables.h, src/tables.c, src/output.c: Comment changes.
13591 2002-10-20 Akim Demaille <akim@epita.fr>
13593 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
13596 2002-10-20 Akim Demaille <akim@epita.fr>
13598 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
13599 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
13601 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
13603 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
13604 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
13607 2002-10-19 Paul Eggert <eggert@twinsun.com>
13609 Do not create a temporary file, as that involves security and
13610 cleanup headaches. Instead, use a pair of pipes.
13611 Derived from a suggestion by Florian Krohm.
13612 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
13613 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
13614 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
13615 (BISON_PREREQ_SUBPIPE): Add.
13616 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
13617 Add subpipe.h, subpipe.c.
13618 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
13619 * po/POTFILES.in: Add lib/subpipe.c.
13620 * src/output.c: Include "subpipe.h".
13621 (m4_invoke): Remove decl.
13622 (scan_skel): New decl.
13623 (output_skeleton): Use pipe rather than temporary file for m4 input.
13624 Check that m4sugar.m4 is readable, to avoid deadlock.
13625 Check for pipe I/O error.
13626 * src/scan-skel.l (readpipe): Remove decl.
13627 (scan_skel): New function, to be used in place of m4_invoke.
13628 Read from stream rather than file.
13630 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
13631 float, as this generates a warning on Solaris 8 + GCC 3.2 with
13632 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
13633 this generates a more-accurate value anyway.
13635 * lib/timevar.c (timervar_accumulate): Rename locals to
13636 avoid confusion with similarly-named more-global.
13637 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
13639 * src/output.c (prepare): Use xstrdup to convert char const *
13640 to char *, to avoid GCC warning.
13642 2002-10-19 Akim Demaille <akim@epita.fr>
13644 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
13645 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
13646 Use them to have `calc.y' ready for %pure-parser.
13647 * data/yacc.c (YYLEX): Pass a yylex return type to
13648 b4_c_function_call.
13650 2002-10-19 Akim Demaille <akim@epita.fr>
13652 Prototype support of %lex-param and %parse-param.
13654 * src/parse-gram.y: Add the definition of the %lex-param and
13655 %parse-param tokens, plus their rules.
13656 Drop the `_' version of %glr-parser.
13658 * src/scan-gram.l (INITIAL): Scan them.
13659 * src/muscle_tab.c: Comment changes.
13660 (muscle_insert, muscle_find): Rename `pair' as `probe'.
13661 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
13662 (muscle_entry_s): The `value' member is no longer const.
13663 Adjust all dependencies.
13664 * src/muscle_tab.c (muscle_init): Adjust: use
13665 MUSCLE_INSERT_STRING.
13666 Initialize the obstack earlier.
13667 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
13668 (muscle_pair_list_grow): New.
13669 * data/c.m4 (b4_c_function_call, b4_c_args): New.
13670 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
13671 * tests/calc.at: Use %locations, not --locations.
13672 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
13674 2002-10-19 Akim Demaille <akim@epita.fr>
13676 * src/getargs.c (usage): Take status as argument and exit
13678 Report the traditional `Try ... --help' message when status != 0.
13679 (usage, version): Don't take a FILE * as arg, it is pointless.
13680 (getargs): When there is an incorrect number of arguments, make it
13681 an error, and report it GNUlically thanks to `usage ()'.
13683 2002-10-18 Paul Eggert <eggert@twinsun.com>
13685 * data/glr.c (yyreportParseError): Don't assume that sprintf
13686 yields the length of the printed string, as this is not true
13687 on SunOS 4.1.4. Reported by Peter Klein.
13689 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
13690 * tests/conflicts.at (%nonassoc and eof): Likewise.
13691 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
13693 2002-10-17 Akim Demaille <akim@epita.fr>
13695 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
13696 * src/getargs.c (trace_types, trace_args): Adjust.
13697 * src/reader.c (grammar_current_rule_prec_set)
13698 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
13699 Standardize error messages.
13700 And s/@prec/%prec/!
13701 (reader): Use trace_flag to enable scanner/parser debugging,
13702 instead of an adhoc scheme.
13703 * src/scan-gram.l: Remove trailing debugging code.
13705 2002-10-16 Paul Eggert <eggert@twinsun.com>
13707 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
13710 * NEWS: Officially drop support for building Bison with K&R C,
13711 since it didn't work anyway and it's not worth worrying about.
13712 * Makefile.maint (wget_files): Remove ansi2knr.c.
13713 (ansi2knr.c-url_prefix): Remove.
13714 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
13715 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13716 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13718 2002-10-15 Paul Eggert <eggert@twinsun.com>
13720 Stop using the "enum_" trick for K&R-style function definitions;
13721 it confused me, and I was the author! Instead, assume that people
13722 who want to use K&R C compilers (when using these modules in GCC,
13723 perhaps?) will run ansi2knr.
13725 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
13726 All uses of "enum_" changed to "enum ".
13727 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
13728 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.

13738 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
13739 Use function prototypes; this removes the need for declaring
13740 static functions simply to provide their prototypes.

13819 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
13821 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
13822 for portability to K&R hosts. Fix typo: signed char is guaranteed
13823 only to 127, not to 128.
13824 * data/glr.c (yysigned_char): New type.
13825 * data/yacc.c (yysigned_char): Likewise.
13826 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
13828 2002-10-13 Paul Eggert <eggert@twinsun.com>
13830 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
13831 true due to limited range of data type" warning from GCC.
13833 * data/c.m4 (b4_token_defines): Protect against double-inclusion
13834 by wrapping enum yytokentype's definition inside #ifndef
13835 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
13837 2002-10-13 Akim Demaille <akim@epita.fr>
13839 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
13840 Un yy- yyrhs to avoid the name clash with the global YYRHS.
13842 2002-10-13 Akim Demaille <akim@epita.fr>
13844 * Makefile.maint: Update from Autoconf 2.54.
13845 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
13847 2002-10-13 Akim Demaille <akim@epita.fr>
13849 * src/print.c (print_state): Separate the list of solved conflicts
13850 from the other items.
13851 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
13853 2002-10-13 Akim Demaille <akim@epita.fr>
13855 Let nondeterministic skeletons be usable with deterministic
13858 With the patch, GAWK compiled by GCC without -O2 passes its test
13859 suite using a GLR parser driven by LALR tables. It fails with -O2
13860 because `struct stat' gives two different answers on my machine:
13861 88 (definition of an auto var) and later 96 (memset on this var).
13862 Hence the stack is badly corrumpted. The headers inclusion is to
13863 blame: if I move the awk.h inclusion before GLR's system header
13864 inclusion, the two struct stat have the same size.
13866 * src/tables.c (pack_table): Always create conflict_table.
13867 (token_actions): Always create conflict_list.
13868 * data/glr.c (YYFLAG): Remove, unused.
13870 2002-10-13 Akim Demaille <akim@epita.fr>
13872 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
13874 (VALGRIND, GXX): New.
13875 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
13876 * tests/bison.in: Run $PREBISON a pre-command.
13877 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
13878 (maintainer-check-g++): New.
13879 * Makefile.am (maintainer-check): New.
13881 2002-10-13 Akim Demaille <akim@epita.fr>
13883 * data/glr.c: Formatting changes.
13884 Tweak some trace messages to match yacc.c's.
13886 2002-10-13 Akim Demaille <akim@epita.fr>
13888 GLR parsers sometimes raise parse errors instead of performing the
13890 Reported by Charles-Henry de Boysson.
13892 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
13893 check the length of the traces when %glr.
13894 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
13896 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
13898 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
13899 (yyltype): Remove the yy prefix from the member names.
13900 (yytable): Complete its comment.
13901 (yygetLRActions): Map error action number from YYTABLE from
13903 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
13904 (which was a bug: it should have been YYTABEL_NINF, and yet it was
13905 not satisfying as we could compare an YYACTION computed from
13906 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
13907 only value for error actions.
13908 (yyreportParseError): In verbose parse error messages, don't issue
13909 `error' in the list of expected tokens.
13910 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
13911 next action to perform to match glr.c's decoding.
13912 (yytable): Complete its comment.
13914 2002-10-13 Paul Eggert <eggert@twinsun.com>
13916 Fix problem reported by Henrik Grubbstroem in
13917 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
13918 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
13919 because the Bison parser reads the second action before reducing
13921 * src/scan-gram.l (rule_length): New static var.
13922 Use it to keep track of the rule length in the scanner, since
13923 we can't expect the parser to be in lock-step sync with the scanner.
13924 (handle_action_dollar, handle_action_at): Use this var.
13925 * tests/actions.at (Exotic Dollars): Test for the problem.
13927 2002-10-12 Paul Eggert <eggert@twinsun.com>
13929 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
13930 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
13931 Include <sys/time.h> when checking for clock_t and struct tms.
13932 Use same include order as source.
13933 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
13934 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
13936 * lib/timevar.c: Update copyright date and clarify comments.
13937 (get_time) [IN_GCC]: Keep the GCC version for reference.
13939 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
13940 GCC version as of today, then merge Bison's changes.
13941 Change "GCC" to "Bison" in copyright notice. timevar.def's
13942 author is Akim, so change that too.
13944 * src/reader.c (grammar_current_rule_check):
13945 Don't worry about the default action if $$ is untyped.
13946 Prevents bogus warnings reported by Jim Gifford in
13947 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
13949 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
13950 * data/glr.c, data/lalr1.cc, data/yacc.c:
13951 Output token definitions before the first part of user declarations.
13952 Fixes compatibility problem reported by Jim Gifford for kbd in
13953 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
13955 2002-10-11 Paul Eggert <eggert@twinsun.com>
13957 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
13958 (yyparse): here. This undoes some of the 2002-07-25 change.
13959 Compatibility problem reported by Ralf S. Engelschall with
13960 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
13962 2002-10-11 Akim Demaille <akim@epita.fr>
13964 * tests/regression.at Characters Escapes): New.
13965 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
13967 Reported by Jan Nieuwenhuizen.

13973 2002-10-10 Paul Eggert <eggert@twinsun.com>
13975 Portability fixes for bitsets; this also avoids several GCC
13978 * lib/abitset.c: Include <stddef.h>, for offsetof.
13979 * lib/lbitset.c: Likewise.
13981 * lib/abitset.c (abitset_bytes): Return a size that is aligned
13982 properly for vectors of objects. Do not assume that adding a
13983 header size to a multiple of a word size yields a value that is
13984 properly aligned for the whole union.
13985 * lib/bitsetv.c (bitsetv_alloc): Likewise.
13987 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
13988 unique names for structures.
13989 * lib/ebitset.c (ebitset_bytes): Likewise.
13990 * lib/lbitset.c (lbitset_bytes): Likewise.
13992 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

13997 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
13998 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
13999 to improve the type-checking that GCC can do.
14000 * lib/bitset.c (bitset_op4_cmp): Likewise.
14001 * lib/bitset_stats.c (bitset_stats_count,
14002 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

14009 bitset_stats_andn_or_cmp, bitset_stats_or_and,
14010 bitset_stats_or_and_cmp): Likewise.
14011 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
14012 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,

14017 * lib/ebitset.h: Likewise.
14018 * lib/lbitset.h: Likewise.
14020 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
14021 All instances of parameters of type enum bitset_opts are now of
14022 type enum_bitset_opts, to conform to the C Standard, and similarly
14023 for enum_bitset_type.
14024 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14025 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14027 Do not use "struct bitset_struct" to mean different things in
14028 different modules. Not only is this confusing, it violates
14029 the C Standard, which requires that structure types in different
14030 modules must be compatible if one is to be passed to the other.
14031 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
14032 All instances of "struct bitset_struct *" replaced with "bitset".
14033 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
14034 (union bitset_union, struct abitset_struct, struct ebitset_struct,
14035 struct lbitset_struct, struct bitset_stats_struct): New types.
14036 All uses of struct bitset_struct changed to union bitset_union,

14041 struct bitset_struct): Remove.
14042 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
14043 bitset_struct): Remove.
14044 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
14047 Do not call a function of type T using a call that assumes the
14048 function is of a different type U. Standard C requires that a
14049 function must be called with a type that is compatible with its
14051 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
14053 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
14055 * lib/ebitset.c (PFV): Remove.
14056 * lib/lbitset.c (PFV): Likewise.

14063 lbitset_xor): New functions.
14064 (lbitset_vtable): Use them.
14066 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
14069 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
14071 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
14072 Use offsetof, for simplicity.
14074 2002-10-06 Paul Eggert <eggert@twinsun.com>
14076 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
14077 the same width as int. This reapplies a hunk of the 2002-08-12 patch
14078 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
14079 which was inadvertently undone by the 2002-09-30 patch.
14080 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
14081 the same width as int.
14083 2002-10-04 Paul Eggert <eggert@twinsun.com>
14087 * configure.ac (AC_INIT), NEWS: Increment version number.
14089 * doc/bison.texinfo: Minor spelling, grammar, and white space
14091 (Symbols): Mention that any negative value returned from yylex
14092 signifies end-of-input. Warn about negative chars. Mention
14093 the portable Standard C character set.
14095 The GNU coding standard says CFLAGS and YFLAGS are reserved
14096 for the installer to set.
14097 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
14098 * src/Makefile.am (AM_CFLAGS): Likewise.
14099 (AM_YFLAGS): Renamed from YFLAGS.
14101 Fix some MAX and MIN problems.

14104 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
14105 * src/reader.c (reader): Use it.
14107 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
14108 POSIX 1003.1-2001 has removed fgrep.
14110 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
14112 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
14113 interpreted as signed.

14183 to BITSET_WINDEX_MAX.
14185 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
14186 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

14285 2002-09-06 Paul Eggert <eggert@twinsun.com>
14287 * doc/bison.texinfo (Conditions): Make explicit that the GPL
14288 exception applies only to yacc.c. This is a modification of a
14289 patch originally suggested by Akim Demaille.

14341 as int, and similarly for yyposn and YYINDEX.

14383 PROTOTYPES to check for prototypes, and "defined __STDC__" to

14387 size_t; the old version tried to do this but casted improperly.
14388 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
14389 (bitset_test): Now returns int, not unsigned long.
14391 * lib/bitset_stats.c: Include "gettext.h".

14437 (handle_action_dollar, handle_action_at): Don't use isdigit,
14438 as it mishandles negative chars and it may not work as expected
14439 outside the C locale.
14441 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14442 this is a GCC extension and is not portable to other compilers.

14449 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
14452 * tests/regression.at: Do not use 'cc -c input.c -o input';
14453 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
14455 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
14456 exit status as failure, not just exit status 1. Sun C exits
14457 with status 2 sometimes.
14459 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
14460 Use it for the two large tests.

14479 * tests/conflicts.at, tests/reduce.at: Adjust.

14624 different: save its reduction (accept) instead of having a state
14625 without any action (no shift or goto, no reduce).
14626 Note: the final state is now a ``regular'' state, i.e., the
14627 parsers now contain `reduce 0' as default reduction.
14628 Nevertheless, since they decide to `accept' when yystate =
14629 final_state, they still will not reduce rule 0.

14675 yycontrol without making too strong assumptions on the parser
14677 * src/output.c (prepare_tokens): Use the real 0th value of
14678 token_translations instead of `0'.
14679 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
14681 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
14682 for the time being: %locations ought to provide it to yyerror.
14684 2002-07-25 Akim Demaille <akim@epita.fr>
14686 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
14687 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
14688 * tests/regression.at (Web2c Actions): Adjust.
14690 2002-07-25 Akim Demaille <akim@epita.fr>

14695 * src/nullable.c, src/output.c, src/print.c, src/reader.c
14696 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
14697 Iterate from 0 to nrules.
14698 Use rule_number_as_item_number and item_number_as_rule_number.
14699 Adjust to `derive' now containing possibly 0.
14700 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
14701 Handle the `- 1' part in rule numbers from/to item numbers.

16226 b4_lhs_location, b4_rhs_value, and b4_rhs_location.

16383 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
16384 full stderr, and strip it according to the bison options, instead

16388 Add an invocation exercising the error token.
16389 Add an invocation demonstrating a stupid error message.
16390 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

17058 (prepare): Given that for the time being changesyntax is not
17059 usable in M4, rename the muscles using `-' to `_'.

17161 * src/system.h: Need to define __attribute__ away for non-GCC
17162 compilers as well (i.e., the vendor C compiler).
17163 Suggested by Albert Chin-A-Young.
17165 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
17167 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
17168 canonical definition.
17169 * src/system.h: Use the canonical definition for PARAMS (avoids
17170 a conflict with the macro from lib/hash.h).
17172 2002-01-11 Akim Demaille <akim@epita.fr>
17174 * configure.in: Use AC_FUNC_STRNLEN.
17175 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
17177 2002-01-09 Akim Demaille <akim@epita.fr>
17179 * src/files.c, src/files.h (output_infix): New.
17180 (tab_extension): Remove.
17181 (compute_base_names): Compute the former, drop the latter.
17182 * src/output.c (prepare): Insert the muscles `output-infix', and
17184 * src/parse-skel.y (string, string.1): New.
17185 (section.header): Use it.
17186 (section.yacc): Remove.
17187 (prefix): Remove too.
17188 * src/scan-skel.l: Adjust.
17189 * src/bison.simple, src/bison.hairy: Adjust.
17191 2002-01-09 Akim Demaille <akim@epita.fr>
17193 * configure.in (WERROR_CFLAGS): Compute it.
17194 * src/Makefile.am (CFLAGS): Pass it.
17195 * tests/atlocal.in (CFLAGS): Idem.
17196 * src/files.c: Fix a few warnings.
17197 (get_extension_index): Remove, unused.
17199 2002-01-08 Akim Demaille <akim@epita.fr>
17201 * src/getargs.c (AS_FILE_NAME): New.
17202 (getargs): Use it to convert DOSish file names.
17203 * src/files.c (base_name): Rename as full_base_name to avoid
17204 clashes with `base_name ()'.
17205 (filename_split): New.
17206 (compute_base_names): N-th rewrite, using filename_split.
17208 2002-01-08 Akim Demaille <akim@epita.fr>
17210 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
17211 New, stolen from the Fileutils 4.1.
17212 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
17213 * configure.in: Check for the presence of memrchr, and of its
17216 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
17218 * lib/hash.h (__P): Added definition for this macro.
17219 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
17220 BUILT_SOURCES, to ensure they are generated first.
17221 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
17222 %error-verbose to allow bootstrapping with bison 1.30x.
17224 2002-01-06 Akim Demaille <akim@epita.fr>
17226 * src/reader.c (parse_braces): Don't fetch the next char, the
17227 convention is to fetch on entry.
17228 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
17229 'switch' without a following semicolon.
17230 * tests/regression.at (braces parsing): New.
17232 2002-01-06 Akim Demaille <akim@epita.fr>
17234 Bison is dead wrong in its RR conflict reports.
17236 * tests/torture.at (GNU Cim Grammar): New.
17237 * src/conflicts.c (count_rr_conflicts): Fix.
17239 2002-01-06 Akim Demaille <akim@epita.fr>
17241 Creating package.m4 from configure.ac causes too many problems.
17243 * tests/Makefile.am (package.m4): Create it by hand,
17244 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
17246 2002-01-06 Akim Demaille <akim@epita.fr>
17248 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
17251 2002-01-04 Paul Eggert <eggert@twinsun.com>
17253 * doc/bison.texinfo (Debugging):
17254 Remove YYSTDERR; it's no longer defined or used.
17255 Also, s/cstdio.h/cstdio/.
17257 2002-01-03 Akim Demaille <akim@epita.fr>
17259 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
17261 2002-01-03 Akim Demaille <akim@epita.fr>
17263 * src/parse-skel.y (process_skeleton): Don't bind the parser's
17264 tracing code to --trace, wait for a better --trace option, with
17267 2002-01-03 Akim Demaille <akim@epita.fr>
17269 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17270 The ISO C++ standard is extremely clear about it: stderr is
17271 considered a macro, not a regular symbol (see table 94 `Header
17272 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17273 Therefore std:: does not apply to it. It still does with fprintf.
17274 Also, s/cstdio.h/cstdio/.
17276 2002-01-03 Akim Demaille <akim@epita.fr>
17278 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17279 for non system headers.
17281 2002-01-02 Akim Demaille <akim@epita.fr>
17283 Equip the skeleton chain with location tracking, runtime trace,
17284 pure parser and scanner.
17286 * src/parse-skel.y: Request a pure parser, locations, and prefix
17288 (%union): Having several members with the same type does not help
17289 type mismatches, simplify.
17290 (YYPRINT, yyprint): New.
17291 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17292 (skel_error): this.
17294 * src/scan-skel.l: Adjust to these changes.
17295 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17296 (LOCATION_PRINT, skel_control_t): New.
17298 2001-12-30 Akim Demaille <akim@epita.fr>
17300 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17301 replace `gb' with BLANKS.
17302 * src/scan-skel.l: Adjust.
17304 2001-12-30 Akim Demaille <akim@epita.fr>
17306 * src/system.h: We don't need nor want bcopy.
17307 Throw away MS-DOS crap: we don't need getpid.
17308 * configure.in: We don't need strndup. It was even causing
17309 problems: because Flex includes the headers *before* us,
17310 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17312 * lib/xstrndup.c: New.
17313 * src/scan-skel.l: Use it.
17314 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17315 * src/parse-skel.y: Use %directives instead of #defines.
17317 2001-12-30 Akim Demaille <akim@epita.fr>
17319 * src/skeleton.h: New.
17320 * src/output.c (output_parser, output_master_parser): Remove, dead
17322 * src/output.h (get_lines_number, actions_output, guards_output)
17323 (token_definitions_output): Prototype them.
17324 * src/parse-skel.y: Add the license notice.
17325 Include output.h and skeleton.h.
17326 (process_skeleton): Returns void, and takes a single parameter.
17327 * src/scan-skel.l: Add the license notice.
17328 Include skeleton.h.
17329 Don't use %option yylineno: it seems that then Flex imagines
17330 REJECT has been used, and therefore it won't reallocate its
17331 buffers (which makes no other sense to me than a bug). It results
17332 in warnings for `unused: yy_flex_realloc'.
17334 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17336 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17337 (MUSCLE_INSERT_PREFIX): ...to there.
17338 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17339 (MUSCLE_INSERT_PREFIX): Move from here...
17341 * src/bison.hairy: Add a section directive. Put braces around muscle
17342 names. This parser skeleton is still broken, but Bison should not
17343 choke on a bad muscle 'syntax'.
17344 * src/bison.simple: Add a section directive. Put braces around muscle
17347 * src/files.h (strsuffix, stringappend): Add declarations.
17348 (tab_extension): Add declaration.
17349 (short_base_name): Add declaration.
17351 * src/files.c (strsuffix, stringappend): No longer static. These
17352 functions are used in the skeleton parser.
17353 (tab_extension): New.
17354 (compute_base_names): Use the computations done in this function
17355 to guess if the generated parsers should have '.tab' in their
17357 (short_base_name): No longer static.
17359 * src/output.c (output_skeleton): New.
17360 (output): Disable call to output_master_parser, and give a try to
17361 a new skeleton handling system.
17362 (guards_output, actions_output): No longer static.
17363 (token_definitions_output, get_lines_number): No longer static.
17365 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17367 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17370 * src/parse-skel.y: New file.
17371 * src/scan-skel.l: New file.
17373 2001-12-29 Akim Demaille <akim@epita.fr>
17375 %name-prefix is broken.
17377 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
17378 Adjust all dependencies.
17379 * tests/headers.at (export YYLTYPE): Strengthen this test: use
17382 Renaming yylval but not yylloc is not consistent. Now we do.
17384 * src/bison.simple: Prefix yylloc if used.
17385 * doc/bison.texinfo (Decl Summary): Document that.
17387 2001-12-29 Akim Demaille <akim@epita.fr>
17389 * doc/bison.texinfo: Promote `%long-directive' over
17391 Remove all references to fixed-output-files, yacc is enough.
17393 2001-12-29 Akim Demaille <akim@epita.fr>
17395 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
17396 user prologue. These are defaults.
17397 * tests/actions.at (Mid-rule actions): Make sure the user can
17398 define YYDEBUG and YYERROR_VERBOSE.
17400 2001-12-29 Akim Demaille <akim@epita.fr>
17402 * src/output.c (header_output): Don't forget to export YYLTYPE and
17404 * tests/headers.at (export YYLTYPE): New, make sure it does.
17405 * tests/regression.at (%union and --defines, Invalid CPP headers):
17407 * tests/headers.at: here.
17409 2001-12-29 Akim Demaille <akim@epita.fr>
17411 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
17413 2001-12-29 Akim Demaille <akim@epita.fr>
17415 * tests/actions.at (Mid-rule actions): Output on a single line
17416 instead of several.
17418 2001-12-29 Akim Demaille <akim@epita.fr>
17420 * doc/bison.texinfo: Formatting changes.
17422 2001-12-29 Akim Demaille <akim@epita.fr>
17424 Don't store the token defs in a muscle, just be ready to output it
17425 on command. Now possible via `symbols'. Fixes a memory leak.
17427 * src/output.c (token_definitions_output): New.
17428 (output_parser, header_output): Use it.
17429 * src/reader.c (symbols_save): Remove.
17431 2001-12-29 Akim Demaille <akim@epita.fr>
17433 * src/bison.simple: Do not provide a default for YYSTYPE and
17434 YYLTYPE before the user's prologue. Otherwise it's hardly... a
17437 2001-12-29 Akim Demaille <akim@epita.fr>
17439 Mid-rule actions are simply... ignored!
17441 * src/reader.c (readgram): Be sure to attach mid-rule actions to
17442 the empty-rule associated to the dummy symbol, not to the host
17444 * tests/actions.at (Mid-rule actions): New.
17446 2001-12-29 Akim Demaille <akim@epita.fr>
17450 * src/reader.c (reader): Free grammar.
17452 2001-12-29 Akim Demaille <akim@epita.fr>
17456 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
17457 since it allocates it for each state, although only one is needed.
17458 (allocate_storage): Do it here.
17460 2001-12-29 Akim Demaille <akim@epita.fr>
17462 * src/options.h, src/options.c (create_long_option_table): Rename
17464 (long_option_table_new): this, with a clearer prototype.
17465 (percent_table): Remove, unused,
17466 * src/getargs.c (getargs): Adjust.
17468 2001-12-29 Akim Demaille <akim@epita.fr>
17470 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
17471 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
17474 2001-12-29 Akim Demaille <akim@epita.fr>
17476 * src/lalr.c (build_relations): Rename `states' as `states1'.
17477 Sorry, I don't understand exactly what it is, no better name...
17479 2001-12-29 Akim Demaille <akim@epita.fr>
17481 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
17482 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
17483 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
17486 2001-12-29 Akim Demaille <akim@epita.fr>
17488 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
17491 2001-12-29 Akim Demaille <akim@epita.fr>
17493 * src/reader.c, src/reader.h (user_toknums): Remove.
17494 Adjust all users to use symbols[i]->user_token_number.
17496 2001-12-29 Akim Demaille <akim@epita.fr>
17498 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
17499 Adjust all users to use symbols[i]->prec or ->assoc.
17501 2001-12-29 Akim Demaille <akim@epita.fr>
17503 * src/reader.c, src/reader.h (tags): Remove.
17504 Adjust all users to use symbols[i]->tag.
17506 2001-12-29 Akim Demaille <akim@epita.fr>
17508 * src/gram.h, src/gram.c (symbols): New, similar to state_table
17510 * src/reader.c (packsymbols): Fill this table.
17512 * src/conflicts.c (resolve_sr_conflict): Adjust.
17513 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
17515 Use symbols[i]->tag instead of tags[i].
17517 2001-12-29 Akim Demaille <akim@epita.fr>
17519 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
17520 In addition, put a comment in there, to replace...
17521 * tests/regression.at (%union and C comments): Remove.
17523 2001-12-29 Akim Demaille <akim@epita.fr>
17525 * tests/regression.at (Web2c Actions): Blindly move the actual
17526 output as expected output. The contents *seem* right to me, but I
17527 can't pretend reading perfectly parser tables... Nonetheless, all
17528 the other tests pass correctly, the table look OK, even though the
17529 presence of `$axiom' is to be noted: AFAICS it is useless (but
17532 2001-12-29 Akim Demaille <akim@epita.fr>
17534 * src/reader.c (readgram): Don't add the rule 0 if there were no
17535 rules read. In other words, add it _after_ having performed
17536 grammar sanity checks.
17537 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
17539 2001-12-29 Akim Demaille <akim@epita.fr>
17541 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
17542 visible, and some states have now a different number.
17544 2001-12-29 Akim Demaille <akim@epita.fr>
17546 * src/reader.c (readgram): Bind the initial rule's lineno to that
17548 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
17549 (Solved SR Conflicts): Adjust rule 0's line number.
17551 2001-12-29 Akim Demaille <akim@epita.fr>
17553 Fix the `GAWK Grammar' failure.
17555 * src/LR0.c (final_state): Initialize to -1 so that we do compute
17556 the reductions of the first state which was mistakenly confused
17557 with the final state because precisely final_state was initialized
17559 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
17560 now noticed by Bison.
17561 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
17562 have a reduction on $default.
17564 2001-12-29 Akim Demaille <akim@epita.fr>
17566 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
17568 * src/closure.c (print_closure): Likewise.
17569 * src/derives.c (print_derives): Likewise.
17570 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
17573 2001-12-29 Akim Demaille <akim@epita.fr>
17575 * src/lalr.c (lookaheads_print): New.
17576 (lalr): Call it when --trace-flag.
17577 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
17580 2001-12-29 Akim Demaille <akim@epita.fr>
17582 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
17583 when walking through ritem, even via rule->rhs.
17584 * src/reduce.c (dump_grammar, useful_production, reduce_output)
17585 (useful_production, useless_nonterminals): Likewise.
17586 (reduce_grammar_tables): Likewise, plus update nritems.
17587 * src/nullable.c (set_nullable): Likewise.
17588 * src/lalr.c (build_relations): Likewise.
17589 * tests/sets.at (Nullable): Adjust.
17590 Fortunately, now, the $axiom is no longer nullable.
17592 2001-12-29 Akim Demaille <akim@epita.fr>
17594 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
17596 * src/gram.c (ritem_longest_rhs): Likewise.
17597 * src/reduce.c (nonterminals_reduce): Likewise.
17598 * src/print_graph.c (print_graph): Likewise.
17599 * src/output.c (output_rule_data): Likewise.
17600 * src/nullable.c (set_nullable): Likewise.
17602 2001-12-29 Akim Demaille <akim@epita.fr>
17604 * src/output.c: Comment changes.
17606 2001-12-27 Paul Eggert <eggert@twinsun.com>
17608 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
17609 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
17610 Sparc, as they were causing more porting problems than the
17611 (minor) performance improvement was worth.
17613 Also, catch up with 1.31's YYSTD.
17615 2001-12-27 Akim Demaille <akim@epita.fr>
17617 * src/output.c (output_gram): Rely on nritems, not the
17618 0-sentinel. See below.
17619 Use -1 as separator, not 0.
17620 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
17621 Rely on -1 as separator in yyrhs, instead of 0.
17622 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
17623 twice `Now at end of input', therefore there are two lines less to
17626 2001-12-27 Akim Demaille <akim@epita.fr>
17628 * tests/regression.at (Unresolved SR Conflicts):
17629 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
17632 2001-12-27 Akim Demaille <akim@epita.fr>
17634 * src/LR0.c (new_state): Recognize the final state by the fact it
17635 is reached by eoftoken.
17636 (insert_start_shifting_state, insert_eof_shifting_state)
17637 (insert_accepting_state, augment_automaton): Remove, since now
17638 these states are automatically computed from the initial state.
17639 (generate_states): Adjust.
17640 * src/print.c: When reporting a rule number to the user, substract
17641 1, so that the axiom rule is rule 0, and the first user rule is 1.
17642 * src/reduce.c: Likewise.
17643 * src/print_graph.c (print_core): For the time being, just as for
17644 the report, depend upon --trace-flags to dump the full set of
17646 * src/reader.c (readgram): Once the grammar read, insert the rule
17647 0: `$axiom: START-SYMBOL $'.
17648 * tests/set.at: Adjust: rule 0 is now displayed, and since the
17649 number of the states has changed (the final state is no longer
17650 necessarily the last), catch up.
17652 2001-12-27 Akim Demaille <akim@epita.fr>
17654 Try to make the use of the eoftoken valid. Given that its value
17655 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
17656 is used instead of > 0 where appropriate, (ii), depend upon nritems
17657 instead of the 0-sentinel.
17659 * src/gram.h, src/gram.c (nritems): New.
17660 Expected to be duplication of nitems, but for the time being...
17661 * src/reader.c (packgram): Assert nritems and nitems are equal.
17662 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
17663 * src/closure.c (print_closure, print_fderives): Likewise.
17664 * src/gram.c (ritem_print): Likewise.
17665 * src/print.c (print_core, print_grammar): Likewise.
17666 * src/print_graph.c: Likewise.
17668 2001-12-27 Akim Demaille <akim@epita.fr>
17670 * src/main.c (main): If there are complains after grammar
17671 reductions, then output the report anyway if requested, then die.
17672 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
17673 * src/reader.c (eoftoken): New.
17674 (parse_token_decl): If the token being defined has value `0', it
17676 (packsymbols): No longer hack `tags' to insert `$' by hand.
17677 Be sure to preserve the value of the eoftoken.
17678 (reader): Make sure eoftoken is defined.
17679 Initialize nsyms to 0: now eoftoken is created just like the others.
17680 * src/print.c (print_grammar): Don't special case the eof token.
17681 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17682 lie anyway, albeit pleasant.
17683 * tests/calc.at: Exercise error messages with eoftoken.
17684 Change the grammar so that empty input is invalid.
17685 Adjust expectations.
17686 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
17688 2001-12-27 Akim Demaille <akim@epita.fr>
17690 * configure.in: Check the protos of strchr ans strspn.
17691 Replace strchr if needed.
17692 * src/system.h: Provide the protos of strchr, strspn and memchr if
17694 * lib/strchr.c: New.
17695 * src/reader.c (symbols_save): Use strchr.
17697 2001-12-27 Akim Demaille <akim@epita.fr>
17699 * src/print.c, src/print_graph.c (escape): New.
17700 Use it to quote the TAGS outputs.
17701 * src/print_graph.c (print_state): Now errors are in red, and
17702 reductions in green.
17703 Prefer high to wide: output the state number on a line of its own.
17705 2001-12-27 Akim Demaille <akim@epita.fr>
17707 * src/state.h, src/state.c (reductions_new): New.
17708 * src/LR0.c (set_state_table): Let all the states have a
17709 `reductions', even if reduced to 0.

17728 2001-12-27 Akim Demaille <akim@epita.fr>
17730 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
17731 * src/print.c: here.
17732 (lookaheadset, shiftset): New, used as additional storage by
17734 (print_results): Adjust.
17735 (print_shifts, print_gotos, print_errs): New, extracted from...
17736 (print_actions): here.
17737 * src/print_graph.c (print_actions): Remove dead code.
17739 2001-12-27 Akim Demaille <akim@epita.fr>
17741 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
17744 2001-12-27 Akim Demaille <akim@epita.fr>
17746 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
17747 (build_relations): Adjust.
17749 2001-12-27 Akim Demaille <akim@epita.fr>
17751 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
17754 2001-12-27 Akim Demaille <akim@epita.fr>
17756 * src/reader.c (packgram): Catch nitems overflows.
17758 2001-12-27 Akim Demaille <akim@epita.fr>
17760 * src/files.c, src/files.h (guard_obstack): Remove.
17761 * src/output.c (output): Adjust.
17762 * src/reader.c (parse_braces): New, factoring...
17763 (copy_action, copy_guard): these two which are renamed as...
17764 (parse_action, parse_guard): these.
17765 As a voluntary consequence, using braces around guards is now
17768 2001-12-27 Akim Demaille <akim@epita.fr>
17770 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
17771 * src/reader.c (symbol_list): `guard' and `guard_line' are new
17773 (symbol_list_new): Adjust.
17774 (copy_action): action_line is the first line, not the last.
17775 (copy_guard): Just as for actions, store the `action' only, not
17776 the switch/case/break flesh.
17777 Don't parse the user action that might follow the guard, let...
17778 (readgram): do it, i.e., now, there can be an action after a
17780 In other words the guard is just explicitly optional.
17781 (packgram): Adjust.
17782 * src/output.c (guards_output): New.
17783 (output_parser): Call it when needed.
17784 (output): Also free the guard and attrs obstacks.
17785 * src/files.c, src/files.h (obstack_save): Remove.
17786 (output_files): Remove.
17787 As a result, if one needs the former `.act' file, using an
17788 appropriate skeleton which requires actions and guards is now
17790 * src/main.c (main): Adjust.
17791 * tests/semantic.at: New.
17792 * tests/regression.at: Use `input.y' as input file name.
17793 Avoid 8+3 problems by requiring input.c when the test needs the

17798 * src/reader.c (symbol_list_new): Be sure to initialize all the
17801 2001-12-27 Akim Demaille <akim@epita.fr>
17803 All the hacks using a final pseudo state are now useless.
17805 * src/LR0.c (set_state_table): state_table holds exactly nstates.
17806 * src/lalr.c (nLA): New.
17807 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
17808 instead of lookaheadsp from the pseudo state (nstate + 1).
17810 2001-12-27 Akim Demaille <akim@epita.fr>
17812 * src/output.c (action_row, token_actions): Use a state_t instead
17813 of a integer, and nlookaheads instead of the following state's

17820 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
17821 (conflicts_print, print_reductions): Use a state_t instead of an
17822 integer when referring to a state.
17823 As much as possible, depend upon nlookaheads, instead of the
17824 `lookaheadsp' member of the following state (since lookaheads of
17825 successive states are successive, the difference between state n + 1
17826 and n served as the number of lookaheads for state n).
17827 * src/lalr.c (add_lookback_edge): Likewise.
17828 * src/print.c (print_core, print_actions, print_state)
17829 (print_results): Likewise.
17830 * src/print_graph.c (print_core, print_actions, print_state)

17843 * src/output.c (prepare): Drop the muscle `ntbase' which
17844 duplicates ntokens.
17845 * src/bison.simple: Formatting/comment changes.
17846 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
17847 is an undocumented synonym.
17849 2001-12-22 Akim Demaille <akim@epita.fr>
17851 * src/output.c (output_table_data): Change the prototype to use
17852 `int' for array ranges: some invocations do pass an int, not a
17854 Reported by Wayne Green.
17856 2001-12-22 Akim Demaille <akim@epita.fr>
17858 Some actions of web2c.y are improperly triggered.
17859 Reported by Mike Castle.
17861 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
17862 * tests/regression.at (Web2c): Rename as...
17863 (Web2c Report): this.
17864 (Web2c Actions): New.
17866 2001-12-22 Akim Demaille <akim@epita.fr>

17872 * tests/regression.at (Web2c): New.
17874 2001-12-18 Akim Demaille <akim@epita.fr>
17876 Some host fail on `assert (!"foo")', which expands to
17877 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
17878 Reported by Nelson Beebee.
17880 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
17881 `#define it_succeeded 0' and `assert (it_succeeded)'.
17883 2001-12-17 Marc Autret <autret_m@epita.fr>
17885 * src/bison.simple: Don't hard code the skeleton line and filename.
17886 * src/output.c (output_parser): Rename 'line' as 'output_line'.
17887 New line counter 'skeleton_line' (skeleton-line muscle).
17889 2001-12-17 Paul Eggert <eggert@twinsun.com>
17891 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
17892 YYDEBUG must be defined to a nonzero value.
17894 * src/bison.simple (yytname): Do not assume that the user defines
17895 YYDEBUG to a properly parenthesized expression.
17897 2001-12-17 Akim Demaille <akim@epita.fr>
17899 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
17900 nlookaheads is a new member.
17902 * src/lalr.h (nlookaheads): Remove this orphan declaration.
17903 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each

17908 * src/files.h, src/files.c (open_files, close_files): Remove.
17909 * src/main.c (main): Don't open/close files, nor invoke lex_free,
17911 * src/reader.c (reader): Do it.
17913 2001-12-17 Akim Demaille <akim@epita.fr>
17915 * src/conflicts.c (print_reductions): Formatting changes.
17917 2001-12-17 Akim Demaille <akim@epita.fr>
17919 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
17920 (flush_reduce): New.
17921 (resolve_sr_conflict): Adjust.
17923 2001-12-17 Akim Demaille <akim@epita.fr>
17925 * src/output.c (output_obstack): Be static and rename as...
17926 (format_obstack): this, to avoid any confusion with files.c's
17928 * src/reader.h (muscle_obstack): Move to...
17929 * src/output.h: here, since it's defined in output.c.
17931 2001-12-17 Akim Demaille <akim@epita.fr>
17933 * src/output.c (action_row, save_column, default_goto)
17934 (sort_actions, matching_state, pack_vector): Better variable
17937 2001-12-17 Akim Demaille <akim@epita.fr>
17939 * src/output.c: Various formatting changes.
17941 2001-12-17 Akim Demaille <akim@epita.fr>
17943 * src/files.c (output_files): Free the output_obstack.
17944 * src/main.c (main): Call print and print_graph conditionally.
17945 * src/print.c (print): Work unconditionally.
17946 * src/print_graph.c (print_graph): Work unconditionally.
17947 * src/conflicts.c (log_resolution): Output only if verbose_flag.
17949 2001-12-16 Marc Autret <autret_m@epita.fr>
17951 * src/output.c (actions_output): Fix. When we use %no-lines,
17952 there is one less line per action.
17954 2001-12-16 Marc Autret <autret_m@epita.fr>
17956 * src/bison.simple: Remove a useless #line directive.
17957 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
17958 * src/output.c (get_lines_number): New.
17959 (output_parser): Adjust, now takes care about the lines of a
17961 Fix line numbering.
17962 (actions_output): Computes the number of lines taken by actions.
17963 (output_master_parser): Insert new skeleton which is the name of
17964 the output parser file name.
17966 2001-12-15 Marc Autret <autret_m@epita.fr>
17968 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
17970 2001-12-15 Marc Autret <autret_m@epita.fr>
17972 * src/output.c (output_gram): Keep track of the hairy one.
17974 2001-12-15 Akim Demaille <akim@epita.fr>
17976 Make `make distcheck' work.
17978 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
17979 system.h which uses libgettext.h.
17981 2001-12-15 Akim Demaille <akim@epita.fr>
17983 * src/nullable.c (set_nullable): Useless rules must be skipped,
17984 otherwise, since we range over their symbols, we might look at a
17985 nonterminal which no longer ``exists'', i.e., it is not counted in
17986 `nvars', hence we overflow our arrays.
17988 2001-12-15 Akim Demaille <akim@epita.fr>
17990 The header can also be produced directly, without any obstack!
17993 * src/files.c, src/files.h (defines_obstack): Remove.
17994 (compute_header_macro): Global.
17995 (defines_obstack_save): Remove.
17996 * src/reader.c (parse_union_decl): No longer output to
17997 defines_obstack: its content can be found in the `stype' muscle
17999 (output_token_translations): Merge into...
18000 (symbols_output): this.
18002 (symbols_save): this.
18004 * src/output.c (header_output): New.
18007 2001-12-15 Akim Demaille <akim@epita.fr>
18009 * src/reader.c (parse_union_decl): Instead of handling two obstack
18010 simultaneously, use one to define the `stype' muscle, and use the
18011 value of the latter to fill defines_obstack.
18012 (copy_comment): Remove.
18013 (copy_comment2): Work for a single obstack.
18015 (copy_comment): this.
18017 2001-12-15 Akim Demaille <akim@epita.fr>
18019 * src/lex.c, src/lex.h (xgetc): No longer static.
18020 * src/reader.c (parse_union_decl): Revamp.
18022 2001-12-15 Akim Demaille <akim@epita.fr>
18024 Still making progress in separating Bison into (i) input, (ii)
18025 process, (iii) output: now we can directly output the parser file
18026 without using table_obstack at all.
18028 * src/files.c, src/files.h (table_obstack): Bye bye.
18029 (parser_file_name): New.
18030 * src/files.c (compute_output_file_names): Compute it.
18031 * src/output.c (actions_output, output_parser)
18032 (output_master_parser): To a file instead of an obstack.
18034 2001-12-15 Akim Demaille <akim@epita.fr>
18036 Attach actions to rules, instead of pre-outputting them to
18039 * src/gram.h (rule_t): action and action_line are new members.
18040 * src/reader.c (symbol_list): Likewise.
18041 (copy_action): Save the actions within the rule.
18042 (packgram): Save them in rule_table.
18043 * src/output.c (actions_output): New.
18044 (output_parser): Use it on `%%actions'.
18045 (output_rule_data): Don't free rule_table.
18047 (prepare): Don't save the `action' muscle.
18048 * src/bison.simple: s/%%action/%%actions/.
18050 2001-12-15 Akim Demaille <akim@epita.fr>
18052 * src/reader.c (copy_action): When --yacc, don't append a `;'
18053 to the user action: let it fail if lacking.
18054 Suggested by Arnold Robbins and Tom Tromey.
18056 2001-12-14 Akim Demaille <akim@epita.fr>
18058 * src/lex.c (literalchar): Simply return the char you decoded, non
18059 longer mess around with obstacks and int pointers.
18060 Adjust all callers.
18062 2001-12-14 Akim Demaille <akim@epita.fr>
18064 * src/lex.c (literalchar): Don't escape the special characters,
18065 just decode them, and keep them as char (before, eol was output as
18066 the 2 char string `\n' etc.).
18067 * src/output.c (output_rule_data): Use quotearg to output the
18070 2001-12-13 Paul Eggert <eggert@twinsun.com>
18072 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
18073 Do not infringe on the global user namespace when using C++.
18074 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
18075 All uses of `fprintf' and `stderr' changed.
18077 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
18079 2001-12-13 Akim Demaille <akim@epita.fr>
18081 The computation of nullable is broken: it doesn't handle empty
18084 * tests/torture.at (GNU AWK Grammar): New.
18085 * tests/sets.at (Nullable): New.
18086 * src/nullable.c (set_nullable): Instead of blindly looping over
18087 `ritems', loop over the rules, and then over their rhs's.
18089 Work around Autotest bugs.
18091 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
18092 frame, because Autotest understand lines starting with a `+' as
18093 traces from the shell. Then, they are not processed properly.
18094 Admittedly an Autotest bug, but we don't have time to wait for
18095 Autotest to catch up.
18096 * tests/regression.at (Broken Closure): Adjust to the new table
18099 * tests/sets.at: here.
18101 2001-12-13 Akim Demaille <akim@epita.fr>
18103 * src/closure.c (closure): Use nrules instead of playing tricks
18104 with BITS_PER_WORD.
18106 2001-12-13 Akim Demaille <akim@epita.fr>
18108 * src/print.c (print_actions): Output the handling of `$' as the
18109 traces do: shifting the token EOF. Before EOF was treated as a
18111 * tests/regression.at: Adjust some tests.
18112 * src/print_graph.c (print_core): Complete the set of items via
18113 closure. The next-to-final and final states are still unsatisfying,
18114 but that's to be addressed elsewhere.
18115 No longer output the rule numbers, but do output the state number.
18116 A single loop for the shifts + gotos is enough, but picked a
18117 distinct color for each.
18118 (print_graph): Initialize and finalize closure.
18120 2001-12-13 Akim Demaille <akim@epita.fr>
18122 * src/reader.c (readgram): Remove dead code, an strip useless
18124 (get_type): Remove, unused.
18126 2001-12-12 Akim Demaille <akim@epita.fr>
18128 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
18129 on that of lib/error.c.
18131 2001-12-12 Akim Demaille <akim@epita.fr>
18133 Some hosts don't like `/' in includes.
18135 * src/system.h: Include libgettext.h without qualifying the path.
18136 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18139 2001-12-11 Marc Autret <autret_m@epita.fr>
18141 * src/output.c (output_parser): Remove useless muscle.
18143 2001-12-11 Marc Autret <autret_m@epita.fr>
18145 * src/bison.simple: Remove #line just before %%epilogue. It
18146 is now handled in ...
18147 * src/reader.c (read_additionnal_code): Add the output of a
18148 #line for the epilogue.
18150 2001-12-10 Marc Autret <autret_m@epita.fr>
18152 * src/reader.c (copy_definition): Re-use CPP-outed code which
18153 replace precedent remove.
18154 * src/bison.simple: Remove #line before %%prologue because
18155 %%input-line is wrong at this time.
18157 2001-12-10 Marc Autret <autret_m@epita.fr>
18159 * src/reader.c (symbols_output): Clean up.
18160 * src/output.c (output_gram, output): Clean up.
18162 2001-12-10 Akim Demaille <akim@epita.fr>
18164 * src/lalr.c (initialize_lookaheads): New. Extracted from...
18165 * src/LR0.c (set_state_table): here.
18166 * src/lalr.c (lalr): Call it.
18168 2001-12-10 Akim Demaille <akim@epita.fr>
18170 * src/state.h (shifts): Remove the `number' member: shifts are
18171 attached to state, hence no longer need to be labelled with a
18174 2001-12-10 Akim Demaille <akim@epita.fr>
18176 Now that states have a complete set of members, the linked list of
18177 shifts is useless: just fill directly the state's shifts member.
18179 * src/state.h (shifts): Remove the `next' member.
18180 * src/LR0.c (first_state, last_state): Remove.
18181 Adjust the callers.
18182 (augment_automaton): Don't look for the shifts that must be added
18183 a shift on EOF: it is those of the state we looked for! But now,
18184 since shifts are attached, it is no longer needed to looking
18185 merely by its id: its number.
18187 2001-12-10 Akim Demaille <akim@epita.fr>
18189 * src/LR0.c (augment_automaton): Better variable locality.
18190 Remove an impossible branch: if there is a state corresponding to
18191 the start symbol being shifted, then there is shift for the start
18192 symbol from the initial state.
18194 2001-12-10 Akim Demaille <akim@epita.fr>
18196 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
18197 only when appropriate: when insert_start_shifting_state' is not
18199 * tests/regression.at (Rule Line Numbers): Adjust.
18201 2001-12-10 Akim Demaille <akim@epita.fr>
18203 * src/LR0.c (augment_automaton): Now that all states have shifts,
18204 merge the two cases addition shifts to the initial state.
18206 2001-12-10 Akim Demaille <akim@epita.fr>
18208 * src/lalr.c (set_state_table): Move to...
18210 * src/lalr.c (lalr): Don't call it...
18211 * src/LR0.c (generate_states): do it.
18212 * src/LR0.h (first_state): Remove, only the table is used.
18214 2001-12-10 Akim Demaille <akim@epita.fr>
18216 * src/LR0.h (first_shift, first_reduction): Remove.
18217 * src/lalr.c: Don't use first_shift: find shifts through the
18220 2001-12-10 Akim Demaille <akim@epita.fr>
18222 * src/LR0.c: Attach shifts to states as soon as they are
18224 * src/lalr.c (set_state_table): Instead of assigning shifts to
18225 state, just assert that the mapping was properly done.
18227 2001-12-10 Akim Demaille <akim@epita.fr>
18229 * src/LR0.c (insert_start_shift): Rename as...
18230 (insert_start_shifting_state): this.
18231 (insert_eof_shifting_state, insert_accepting_state): New.
18232 (augment_automaton): Adjust.
18233 Better locality of the variables.
18234 When looking if the start_symbol is shifted from the initial
18235 state, using `while (... symbol != start_symbol ...)' sounds
18236 better than `while (... symbol < start_symbol ...)': If fail
18237 to see how the order between symbols could be relevant!
18239 2001-12-10 Akim Demaille <akim@epita.fr>
18241 * src/getargs.h: Don't declare `spec_name_prefix' and
18242 `spec_file_prefix', declared by src/files.h.
18243 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18244 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
18245 * src/output.c (prepare): Adjust.
18246 * src/reader.c (symbols_output): Likewise.
18247 * src/vmsgetargs.c: Vaguely adjust, but who cares?
18249 2001-12-10 Akim Demaille <akim@epita.fr>
18251 * src/muscle_tab.c (muscle_init): NULL is a better default than
18254 2001-12-10 Akim Demaille <akim@epita.fr>
18256 * src/reader.c (reader): Calling symbols_output once is enough.
18258 2001-12-10 Akim Demaille <akim@epita.fr>
18260 Now that states have a complete set of members, the linked list of
18261 reductions is useless: just fill directly the state's reductions
18264 * src/state.h (struct reductions): Remove member `number' and
18266 * src/LR0.c (first_reduction, last_reduction): Remove.
18267 (save_reductions): Don't link the new reductions, store them in
18269 * src/lalr.c (set_state_table): No need to attach reductions to
18270 states, it's already done.
18271 * src/output.c (output_actions): No longer free the shifts, then
18272 the reductions, then the states: free all the states and their
18275 2001-12-10 Akim Demaille <akim@epita.fr>
18277 * src/options.c (OPTN, DRTV, BOTH): New.
18278 (option_table): Use them.
18280 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18281 the job of system.h.
18282 * src/options.c: Don't include stdio.h and xalloc.h for the same
18285 2001-12-10 Akim Demaille <akim@epita.fr>
18287 * src/output.c (output, prepare): Make sure the values of the
18288 muscles `action' and `prologue' are 0-terminated.
18290 2001-12-10 Akim Demaille <akim@epita.fr>
18292 Clean up GCC warnings.
18294 * src/reader.c (copy_action): `buf' is not used.
18295 (parse_skel_decl): Be static.
18296 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18297 * src/options.h (create_long_option_table): Have a real prototype.
18298 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18299 (hash_delete_at): Return const void *.
18300 Adjust casts to preserve the const.
18302 2001-12-10 Akim Demaille <akim@epita.fr>
18304 * configure.in: Require 2.52g.
18305 M4 is not needed, but AUTOM4TE is.
18306 * m4/m4.m4: Remove.
18307 * tests/Makefile.am: Adjust.
18309 2001-12-10 Akim Demaille <akim@epita.fr>
18311 One structure for states is enough, even though theoretically
18312 there are LR(0) states and LALR(1) states.
18314 * src/lalr.h (state_t): Remove.
18315 (state_table): Be state_t **, not state_t *.
18316 * src/state.h (core, CORE_ALLOC): Rename as...
18317 (state_t, STATE_ALLOC): this.
18318 Add the LALR(1) members: shifts, reductions, errs.
18319 * src/LR0.c (state_table): Rename as...
18320 (state_hash): this, to avoid name clashes with the global
18322 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18323 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18325 2001-12-10 Akim Demaille <akim@epita.fr>
18327 Bison dumps core on bash.y.
18328 Reported by Pascal Bart.
18330 * src/warshall.c (bitmatrix_print): New.
18332 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18333 j must be the outer loop.
18334 * tests/regression.at (Broken Closure): New.
18336 2001-12-05 Akim Demaille <akim@epita.fr>
18338 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18340 Reported by Peter Hamorsky.
18342 2001-12-05 Akim Demaille <akim@epita.fr>
18344 * src/conflicts.c (err_table): Remove.
18345 (resolve_sr_conflict): Adjust.
18346 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18348 (state_t.reductions, state_t.shifts): this.
18350 2001-12-05 Akim Demaille <akim@epita.fr>
18352 * src/reduce.c (reduce_grammar_tables): No longer disable the
18353 removal of useless rules via CPP but via `if (0)', so that the
18354 compiler still check the code is valid.
18355 For instance, it should have noticed `rline' no longer exists: use
18356 the `line' member of rule_t.
18357 * src/gram.c (dummy, rline): Remove, unused.
18359 2001-12-05 Akim Demaille <akim@epita.fr>
18361 * src/output.c (pack_vector): Use assert, not berror.
18362 * src/main.c (berror): Remove, unused.
18364 2001-12-05 Akim Demaille <akim@epita.fr>
18366 New experimental feature: if --verbose --trace output all the
18367 items of a state, not only its kernel.
18369 * src/print.c (print_core): If `trace_flag', then invoke closure
18370 before outputting the items of the state (print_core is no longer
18371 a correct name them).
18372 (print_results): Invoke new_closure/free_closure if needed.
18374 2001-12-05 Akim Demaille <akim@epita.fr>
18376 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18377 * src/closure.c, src/closure.h (itemsetsize): Rename as...
18378 (nitemset): for consistency with the rest of the project.
18380 2001-12-05 Akim Demaille <akim@epita.fr>
18382 * src/closure.c (print_closure): Improve.
18383 (closure): Use it for printing input and output.
18385 2001-12-05 Akim Demaille <akim@epita.fr>
18387 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
18388 indexed by nonterminals.
18390 2001-12-05 Akim Demaille <akim@epita.fr>
18392 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
18394 * src/warshall.h: Remove accidental duplication of the content.

18408 2001-12-05 Akim Demaille <akim@epita.fr>
18410 * src/output.c (action_row): De-obfuscate
18411 using the good o' techniques: arrays not pointers, variable
18412 locality, BITISSET, RESETBIT etc.
18414 2001-12-05 Akim Demaille <akim@epita.fr>
18416 Pessimize the code to simplify it: from now on, all the states
18417 have a valid SHIFTS, which NSHIFTS is possibly 0.
18419 * src/LR0.c (shifts_new): Be global and move to..
18420 * src/state.c, src/state.h: here.
18421 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
18422 * src/print_graph: Adjust.
18424 2001-12-05 Akim Demaille <akim@epita.fr>
18426 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
18427 * src/conflicts.c: Use it.
18428 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
18429 incorrectly ``simplified''.
18431 2001-12-05 Akim Demaille <akim@epita.fr>
18433 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
18434 using the good o' techniques: arrays not pointers, variable
18435 locality, BITISSET, RESETBIT etc.
18437 2001-12-05 Akim Demaille <akim@epita.fr>
18439 * src/state.h (SHIFT_SYMBOL): New.
18440 * src/conflicts.c: Use it to deobfuscate.

18444 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
18445 (print_reductions): De-obfuscate using the good o' techniques:
18446 arrays not pointers, variable locality, BITISSET.

18450 * src/conflicts.c (print_reductions): Arrays, not pointers.

18469 2001-12-05 Akim Demaille <akim@epita.fr>
18471 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
18472 * src/lalr.c: Use them.
18474 2001-12-05 Akim Demaille <akim@epita.fr>
18476 * src/LR0.c (augment_automaton): Formatting changes.
18477 Better variable locality.

18481 * src/lalr.c (matrix_print): New.
18482 (transpose): Use it.

18485 2001-12-05 Akim Demaille <akim@epita.fr>
18487 * src/lalr.c (maxrhs): Move to...
18488 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
18489 * src/lalr.c (build_relations): Adjust.
18491 2001-12-05 Akim Demaille <akim@epita.fr>
18493 * src/lalr.c (transpose): Free the memory allocated to the
18494 argument, as it is replaced by the results by the unique caller.
18495 (build_relations): Merely invoke transpose: it handles the memory
18497 Improve variable locality.
18498 Avoid variables used as mere abbreviations.
18499 (compute_lookaheads): Use arrays instead of pointers.
18501 2001-12-05 Akim Demaille <akim@epita.fr>
18503 * src/lalr.c (initialize_F): Improve variable locality.
18504 Avoid variables used as mere abbreviations.

18517 2001-12-05 Akim Demaille <akim@epita.fr>
18519 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
18520 the handling of squeue.
18521 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18523 2001-12-05 Akim Demaille <akim@epita.fr>
18525 Because useless nonterminals are now kept alive (instead of being
18526 `destroyed'), we now sometimes examine them, and store information
18527 related to them. Hence we need to know their number, and adjust
18528 memory allocations.
18530 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18532 * src/LR0.c (allocate_itemsets): The memory allocated to
18533 `symbol_count' was used for two different purpose: once to count
18534 the number of occurrences of each symbol, and later reassigned to
18535 `shift_symbol', containing the symbol that can be shifted from a
18537 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18539 (new_itemsets): Allocate `shift_symbol' here.
18540 (allocate_itemsets): symbol_count includes useless nonterminals.
18541 Make room for them.
18542 (free_storage): Use `free', not `XFREE', for pointers that cannot
18545 2001-12-05 Akim Demaille <akim@epita.fr>
18547 * src/nullable.c (set_nullable): Deobfuscate the handling of
18549 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18551 2001-12-05 Akim Demaille <akim@epita.fr>
18553 * src/gram.c, src/gram.h (ritem_print): New.
18554 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
18555 (This useless function was defined only to work around VMS linkers
18556 that can't handle compilation units with variables only).
18557 * src/reduce.c (dump_grammar): Use it to trace the construction of
18560 2001-12-04 Paul Eggert <eggert@twinsun.com>
18562 * src/bison.simple (union yyalloc): Change member names
18563 to be the same as the stack names.
18564 (yyparse): yyptr is now union yyalloc *, not char *.
18565 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
18566 and may generate better code on some machines.
18567 (yystpcpy): Use prototype if __STDC__ is defined, not just
18568 if __cplusplus is defined.
18570 2001-11-30 Akim Demaille <akim@epita.fr>
18572 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
18573 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
18574 Gettext doesn't compile cleanly, and dies with -Werror.
18575 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
18576 Include WARNING_CFLAGS here.
18577 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
18578 before being defined.
18580 2001-11-27 Paul Eggert <eggert@twinsun.com>
18582 * lib/quotearg.h (quotearg_n, quotearg_n_style):
18583 First arg is int, not unsigned.
18584 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
18585 (SIZE_MAX, UINT_MAX): New macros.
18586 (quotearg_n_options): Abort if N is negative.
18587 Avoid overflow check on hosts where size_t is 64 bits and int
18588 is 32 bits, as overflow is impossible there.
18589 Fix off-by-one typo that caused unnecessary reallocation.
18591 2001-11-29 Paul Eggert <eggert@twinsun.com>
18593 Name space cleanup in generated parser.

18600 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
18601 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
18603 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
18604 on user names when possible.
18606 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
18607 Simplify test for whather <alloca.h> exists.
18609 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
18611 (<stdio.h>): Include if YYDEBUG.
18613 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
18614 ! defined (yyoverflow) && ! defined (yymemcpy).
18616 (yymemcpy, yyparse): Rename local variables as needed so that
18617 they all begin with 'yy'.
18619 (yystrlen, yystpcpy): New functions.
18621 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
18624 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
18625 instead of relying on string.h functions. Use YYSTACK_ALLOC
18626 and YYSTACK_FREE instead of malloc and free.
18628 2001-11-30 Akim Demaille <akim@epita.fr>
18630 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
18631 before their first uses.

18640 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
18641 if body instead of `;' to pacify GCC's warnings.
18643 2001-11-30 Akim Demaille <akim@epita.fr>
18645 Instead of mapping the LHS of unused rules to -1, keep the LHS
18646 valid, but flag the rules as invalid.
18648 * src/gram.h (rule_t): `useful' is a new member.
18649 * src/print.c (print_grammar): Adjust.
18650 * src/derives.c (set_derives): Likewise.
18651 * src/reader.c (packgram, reduce_output): Likewise.

18665 useless nonterminals, move them at the end of the symbol arrays.
18666 (reduce_output): Adjust.
18667 * tests/reduce.at (Useless Nonterminals): Adjust.
18669 2001-11-30 Akim Demaille <akim@epita.fr>

18672 (nonterminals_reduce): New, extracted from...
18673 (reduce_grammar_tables): here.
18674 (reduce_grammar): Call nonterminals_reduce.
18676 2001-11-29 Paul Eggert <eggert@twinsun.com>

18683 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
18684 an arbitrary restriction on hosts where size_t is wider than int.
18686 (yyparse): Don't dump core if alloca or malloc fails; instead, report
18687 a parser stack overflow. Allocate just one block of memory for all
18688 three stacks, instead of allocating three blocks; this typically is
18689 faster and reduces fragmentation.
18691 Do not limit the number of items in the stack to a value that fits
18692 in 'int', as this is an arbitrary limit on hosts with 64-bit
18693 size_t and 32-bit int.

20756 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
20757 s/PFILE1/BISON_HAIRY/.
20758 Adjust dependencies.
20760 2000-11-03 Akim Demaille <akim@epita.fr>
20762 For some reason, this was not applied.
20764 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

20777 (done): Rename as...
20778 (output_files): this.
20779 Use `obstack_save'.
20780 * src/main.c (main): Don't use `atexit' to register `done', since
20781 it no longer has to remove tmp files, just call `output_files'
20782 when there are no errors.
20784 2000-11-02 Akim Demaille <akim@epita.fr>
20786 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

20788 * src/files.h: Formatting changes.
20790 2000-11-02 Akim Demaille <akim@epita.fr>
20792 Remove the last uses of mktemp and unlink/delete.
20794 * src/files.c (fdefines, ftable): Removed.

20858 (copy_guard): Adjust.
20860 2000-10-16 Akim Demaille <akim@epita.fr>
20862 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

20886 2000-10-04 Akim Demaille <akim@epita.fr>
20888 When a literal string is used to define two different tokens,
20889 `bison -v' segfaults.
20890 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
20892 * tests/regression.m4: New file.
20893 Include the core of the sample provided by Piotr Gackiewicz.
20894 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
20897 2000-10-04 Akim Demaille <akim@epita.fr>
20899 * src/reader.c (parse_expect_decl): Keep `count' within the size
20903 2000-10-02 Paul Eggert <eggert@twinsun.com>

20914 2000-10-02 Akim Demaille <akim@epita.fr>
20916 * src/derives.c, src/print.c, src/reduce.c: To ease the
20917 translation, move some `\n' out of the translated strings.
20919 2000-10-02 Akim Demaille <akim@epita.fr>
20921 The location tracking mechanism is precious for parse error
20922 messages. Nevertheless, it is enabled only when `@n' is used in
20923 the grammar, which is a different issue (you can use it in error
20924 message, but not in the grammar per se). Therefore, there should
20925 be another means to enable it.
20927 * src/getargs.c (getargs): Support `--locations'.
20928 (usage): Report it.
20929 * src/getargs.h (locationsflag): Export it.
20930 * src/lex.c (percent_table): Support `%locations'.
20931 * src/reader.c (yylsp_needed): Remove this variable, now replaced
20932 with `locationsflag'.
20933 * doc/bison.texinfo: Document `--locations' and `%locations'.
20935 * tests/calc.m4: Test it.
20937 For regularity of the names, replace each
20938 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
20939 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
20940 In addition replace each `flag' with `_flag'.
20942 2000-10-02 Akim Demaille <akim@epita.fr>
20944 Also test parse error messages, including with YYERROR_VERBOSE.
20946 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
20948 Use it to check the computations.
20949 Use it to check `nonassoc' is honored.
20950 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
20951 `--yyerror-verbose'.
20952 (_AT_CHECK_CALC): Adjust to this option.

20955 2000-10-02 Akim Demaille <akim@epita.fr>
20957 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20958 the latter demonstrates a flaw in the handling of non debugging
20959 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20960 was used in order to simplify:
20976 unfortunately this leads to a CPP conflict when
20977 `--name-prefix=foo' is used since it produces `#define yydebug
20980 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
20981 (YYDPRINTF): New macro.
20983 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
20985 Also test `--verbose', `--defines' and `--name-prefix'.

20989 Improve the readability of the produced parsers.
20991 * src/bison.s1: Formatting changes.
20992 Improve the comment related to the `$' mark.
20993 (yydefault): Don't fall through to `yyresume': `goto' there.
20994 * src/output.c (output_parser): When the `$' is met, skip the end
20996 New variable, `number_of_dollar_signs', to check there's exactly
20997 one `$' in the parser skeleton.
20999 2000-10-02 Akim Demaille <akim@epita.fr>
21001 * lib/xstrdup.c: New file, from the fileutils.
21002 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
21003 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
21004 instead of strlen + xmalloc + strcpy.
21005 * src/symtab.c (copys): Remove, use xstrdup instead.
21007 2000-10-02 Akim Demaille <akim@epita.fr>
21009 * src/gram.h (associativity): New enum type which replaces the
21010 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
21011 `right_assoc', `left_assoc' and `non_assoc'.
21012 Adjust all dependencies.
21013 * src/reader.c: Formatting changes.
21014 (LTYPESTR): Don't define it, use it as a literal in
21015 `reader_output_yylsp'.
21016 * src/symtab.h (symbol_class): New enum type which replaces the
21017 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
21018 `sunknown', `stoken and `snterm'.
21020 2000-10-02 Akim Demaille <akim@epita.fr>
21022 * src/getargs.c (fixed_outfiles): Rename as...
21023 (yaccflag): for consistency and accuracy.
21024 Adjust dependencies.
21026 2000-10-02 Akim Demaille <akim@epita.fr>
21028 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21029 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21030 difficult and introduced a lot of core dump. It turns out that
21031 Bison used an implementation of `xmalloc' based on `calloc', and
21032 at various places it does depend upon the initialization to 0. I
21033 have not tried to isolate the pertinent places, and all the former
21034 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21035 someone should address this issue.
21037 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
21038 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

21048 * src/system.h: Include `assert.h'.
21050 2000-10-02 Akim Demaille <akim@epita.fr>
21052 * src/state.h (nstates, final_state, first_state, first_shift)
21053 (first_reduction): Move their exportation from here...
21054 * src/LR0.h: to here.
21055 Adjust dependencies.
21056 * src/getargs.c (statisticsflag): New variable.
21057 Add support for `--statistics'.

21094 Propagate its inclusion.
21095 * src/reduce.c: Topological sort and other formatting changes.
21096 (bool, TRUE, FALSE): Move their definition to...
21097 * src/system.h: here.
21099 2000-10-02 Akim Demaille <akim@epita.fr>
21101 * src/files.c: Formatting changes.
21102 (tryopen, tryclose, openfiles): Rename as...
21103 (xfopen, xfclose, open_files): this.
21104 (stringappend): static.

21128 * src/lalr.c: Formatting changes, topological sorting etc.
21130 2000-10-02 Akim Demaille <akim@epita.fr>
21132 * src/output.c (token_actions): Introduce a temporary array,
21133 YYDEFACT, that makes it possible for this function to use
21134 output_short_table.
21136 2000-10-02 Akim Demaille <akim@epita.fr>
21138 `user_toknums' is output as a `short[]' in `output.c', while it is
21139 defined as a `int[]' in `reader.c'. For consistency with the
21140 other output tables, `user_toknums' is now defined as a table of

21184 * src/system.h: Define PARAMS.

21406 There is now a pseudo variable @$ (readble and writable), location
21407 of the lhs of the rule (by default ranging from the location of
21408 the first symbol of the rhs, to the location of the last symbol,

21444 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
21445 One `#if YYDEBUG' remains, since it uses variables which are

21470 Bump to bison 1.28a, 1.29 has never been released.
21471 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are

22137 an invalid character. Do not abort.
22138 (read_declarations, copy_guard, copy_action): Use
22139 printable_version to avoid unprintable characters in printed output.

22168 always contain the token. This includes growing the token
22169 buffer while reading an integer.
22170 (parse_percent_token): Replaced if-else statement with percent_table.
22171 (parse_percent_token): Added % declarations as another
22172 way to specify the flags -n, -l, and -r. Also added hooks for
22173 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22174 major changes to files.c.
22175 (lex) Retain in the incoming stream a character following
