752009-04-04 Joel E. Denny <jdenny@ces.clemson.edu>
76
77 Replace BISON_PROG_GNU_M4 with Autoconf's AC_PROG_GNU_M4.
78 If the first m4 in $PATH is wrong, it keeps looking. Moreover, its
79 requirements for a correct m4 are stricter.
80 * m4/m4.m4: Make it a symbolic link to submodules/autoconf/m4/m4.m4.
81 * configure.ac: Update to use AC_PROG_GNU_M4.
82 Reported by Eric Blake.
83
842009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>

98 * src/parse-gram.y (PERCENT_DEBUG, PERCENT_ERROR_VERBOSE): Token
99 definitions and associated rules, replaced by....
100 (PERCENT_FLAG): this new token type, and rule.
101 * src/scan-gram.l (RETURN_PERCENT_FLAG): New.

120
121 Treat %error-verbose as %define error_verbose.
122 This allows to pass -Derror_verbose on the command line. Better
123 yet, it allows to pass -Derror_verbose=$(ERROR_VERBOSE), with
124 ERROR_VERBOSE being defined as false or true.
125 * data/bison.m4 (b4_percent_define_if_define): Instead of relying
126 on b4_percent_define_ifdef, for does not check the defined value,
127 but only whether the symbol is defined, rely on
128 b4_percent_define_flag_if, so that a value of "false" is processed
129 as a false.
130 If not defined, define the flag to "false".
131 (b4_error_verbose_if): New.
132 * data/glr.c, data/lalr1.cc, data/yacc.c: Use it instead of
133 b4_error_verbose_flag.
134 * src/getargs.h, src/getargs.c (error_verbose_flag): Remove.

140 Fix strange %define locations for default values.
141 Reported by Akim Demaille at
142 <http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html>
143 and discussed again starting at
144 <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
145 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
146 because location information is bogus.
147 Use angle brackets to delimit fake file name because square brackets
148 look like underexpanded m4. Choose a better fake file name.
149 Use negative line numbers.
150 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
151 * src/location.c (location_print): If line for a boundary is negative,
152 only print that boundary's file name.
153 * src/location.h: Document that.
154 * tests/skeletons.at (%define Boolean variables: invalid skeleton
155 defaults): Update output.
156
1572009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>
158
159 Pacify ./configure --enable-gcc-warnings.
160 * Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS) because many files
161 in lib won't compile with it.
162 * src/local.mk (src_bison_CFLAGS): Use $(WERROR_CFLAGS) here only.
163
1642009-03-31 Akim Demaille <demaille@gostai.com>
165
166 bootstrap: --help to stdout.
167 * bootstrap (usage): Don't send --help to stderr.
168 Use a here doc instead of a long string.
169
1702009-03-31 Akim Demaille <demaille@gostai.com>
171
172 bootstrap: README-hacking no longer exists
173 * bootstrap (checkout_only_file): Set to HACKING.
174

189
1902009-03-26 Akim Demaille <demaille@gostai.com>
191
192 lalr1.cc: avoid GCC 4.3 warnings.
193 GCC 4.3 now warns about "a || b && c" and asks for explicit
194 parentheses.
195 Reported by Alexandre Duret-Lutz.
196 * data/location.cc: Update copyright years.
197 (Position::operator==): Use parens to make precedence explicit.
198 Compare lines and columns first, as they are more likely to be
199 different, and they are faster to compare.
200
2012009-03-26 Akim Demaille <demaille@gostai.com>
202

2202009-03-02 Akim Demaille <demaille@gostai.com>
221
222 Use locations in the variant example.
223 Yes, this obfuscates the point of this example, variants only.
224 But glr.cc cannot work (yet?) without locations. This change
225 makes it easier to use this example with glr.cc.
226
227 * examples/variant.yy (assert): %define it.
228 (locations): Request them.
229 (yylex): Bind the location to the stage.

238 (b4_symbol_constructor_declare_)
239 (b4_symbol_constructor_define_, b4_symbol_constructor_define):
240 Move to...
241 * data/variant.hh: here.
242 Remove the "b4_variant_if" parts, as variant.hh is loaded only if
243 needed.
244 * data/lalr1.cc: No longer invoke b4_symbol_constructor_define and
245 b4_symbol_constructor_declare, as it is now done by
246 b4_public_types_define and b4_public_types_declare.

339
340 Make yyparser::error public.
341 * data/lalr1.cc: here.
342 There is no good reason to keep it private (and it is convenient
343 to use it from the scanner for instance). It is already public in
344 glr.cc.
345

4832008-12-08 Akim Demaille <demaille@gostai.com>
484
485 Fix regeneration of atconfig.
486 * tests/local.mk (tests/atconfig): The rule was incorrect, but
487 remove it: now that there is no tests/Makefile.am, the top-level
488 Makefile properly updates atconfig when needed.
489
4902008-12-07 Di-an Jan <dianj@freeshell.org>
491
492 Implement the FIXME that ends an user action with a semicolon
493 if it seems necessary.
494 * src/scan-code.l (flex rules section): Flag cpp directive from
495 any `#' to the first unescaped end-of-line. Semicolon is not
496 needed after `;', `{', '}', or cpp directives and is needed after
497 any other token (whitespaces and comments have no effect).
498 * tests/actions.at (Fix user actions without a trailing semicolon):
499 New test.
500 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
501 to make user actions complete statements.
502 Adjust column numbers in error messages.
503 * tests/regression.at (Fix user actions without a trailing semicolon):
504 Remove. Covered by new test.

514 * src/output.c (muscle_insert_item_number_table): Delete unused
515 function.
516
5172008-12-02 Eric Blake <ebb9@byu.net>
518
519 Build testsuite with newer autoconf.
520 * tests/output.at (m4_expand): Don't override in newer autoconf,
521 where the underlying implementation changed.
522 * tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
523 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
524 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
525 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
526 since some of them contain unbalanced ')'.

529
530 Use b4_symbol for printers and destructors everywhere.
531 * data/bison.m4 (b4_symbol_action_location): New.
532 * data/c.m4 (b4_symbol_actions): Remove.
533 Adjust all callers to use by b4_symbol_foreach and the corresponding
534 b4_symbol_printer/destructor macro.
535 * data/glr.cc: Adjust.
536 * data/lalr1.java: Adjust the %destructor sanity check.
537 * src/output.c (symbol_code_props_output): Remove, we no longer
538 need the b4_symbol_printers/destructors tables.
539
5402008-12-01 Akim Demaille <demaille@gostai.com>
541
542 Use b4_symbol_case_.
543 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
544 b4_symbol_case_.
545
5462008-12-01 Akim Demaille <demaille@gostai.com>
547
548 Move b4_symbol based macro to bison.m4.
549 * data/lalr1.cc (b4_symbol_, b4_symbol, b4_symbol_if)
550 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
551 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
552 (b4_type_foreach): Move to...
553 * data/bison.m4: Here.
554 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
555 b4_symbol_value_template instead of b4_symbol_value.
556
5572008-12-01 Akim Demaille <demaille@gostai.com>
558
559 b4_symbol/type_foreach.
560 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
561 Use them.
562
5632008-12-01 Akim Demaille <demaille@gostai.com>
564
565 Use the symbol properties to output the printer/destructor for lalr1.cc.
566 Instead of defining complex list of tuples to define various
567 properties of the symbols, we now prefer to define symbols as
568 "structs" in m4: using the symbol key (its number), and the
569 property name, b4_symbol gives it value. Use this to handle
570 destructors and printers.
571
572 * src/output.c (CODE_PROP): New.
573 (prepare_symbol_definitions): Use it to define the printer and
574 destructor related attributes of the symbols.
575 * data/lalr1.cc (b4_symbol_actions): Rename as...
576 (b4_symbol_action): this.
577 Use b4_symbol instead of 6 arguments.
578 (b4_symbol_printer, b4_symbol_destructor): New.
579 Use them instead of b4_symbol_actions.
580
5812008-12-01 Akim Demaille <demaille@gostai.com>
582
583 Avoid capturing variables too easily.
584 * src/muscle_tab.h (MUSCLE_INSERT_BOOL, MUSCLE_OBSTACK_SGROW): Use
585 v__ and p__ instead of v and p.
586
5872008-12-01 Akim Demaille <demaille@gostai.com>
588
589 Remove spurious empty line before syncline.
590 * data/bison.m4 (b4_syncline): Don't output an empty line before
591 the output.
592
5932008-11-26 Akim Demaille <demaille@gostai.com>
594
595 Convert lib/Makefile.am into lib/local.mk.
596 The real problem is rather gnulib.mk, which itself is extracted
597 from a Makefile.am that gnulib expects to the "recursive". The
598 tool prefix-gnulib-mk converts such a gnulib.mk to be
599 non-recursive. Also, some AC_SUBST variables need to be adjusted.
600
601 * etc/prefix-gnulib-mk: New.
602 * bootstrap (slurp): Use it to convert further gnulib.mk.
603 No longer try to avoid re-creation of lib/gnulib.mk as the changes
604 are deeper.
605 * lib/Makefile.am: Rename as...
606 * lib/local.mk: this.
607 Adjust to be prefixed.
608 * Makefile.am, configure.ac: Adjust.
609 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.

613 s/_FLAGS/FLAGS/.
614 * tests/local.mk (TESTSUITE_FLAGS, AUTOTEST_FLAGS): Rename as...
615 (TESTSUITEFLAGS, AUTOTESTFLAGS): these to compy with the GCS.
616 Reported by Eric Blake.
617
6182008-11-26 Akim Demaille <demaille@gostai.com>
619
620 Use b4_parser_tables_define in glr.cc.
621 * data/glr.c: Use b4_parser_tables_define instead of defining the
622 (deterministic integral) tables by hand.
623
6242008-11-26 Akim Demaille <demaille@gostai.com>
625
626 Use b4_parser_tables_define in Java.

639 * data/bison.m4 (b4_tables_map, b4_tables_declare)
640 (b4_tables_define): Rename as...
641 (b4_integral_parser_tables_map, b4_parser_tables_declare)

647 (b4_integral_parser_table_define)
648 (b4_integral_parser_table_declare): these.
649 (yyrline_): Move the comment where it is actually used.
650 * data/yacc.c: Adjust.
651 (yyrline): Use b4_integral_parser_table_define.
652
6532008-11-26 Akim Demaille <demaille@gostai.com>

662 * data/bison.m4: here.
663 Update the comment for yytable during the flight.
664 (b4_tables_declare, b4_tables_define): New.
665 * data/lalr1.cc: Use them.
666 * data/c.m4 (b4_table_define): New.
667 * data/yacc.c: Use b4_tables_define instead of output the tables
668 by hand.
669 * tests/regression.at (Web2c Actions): Adjust the expected output,
670 the order of the tables changed.
671
6722008-11-26 Akim Demaille <demaille@gostai.com>
673
674 Get rid of (yy)rhs and (yy)prhs.
675 These tables are no longer needed in the parsers, and they don't seem to
676 be useful. They are not documented either.
677
678 * src/output.c (prepare_rules): Get rid of rhs and prhs.
679 Adjust the computation of (yy)r2.
680
6812008-11-26 Akim Demaille <demaille@gostai.com>
682
683 Rule length is unsigned.
684 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
685
6862008-11-26 Akim Demaille <demaille@gostai.com>
687
688 Get rid of lalr1-split.cc.
689 It was no longer maintainer.
690
691 * data/lalr1-split.cc: Remove.
692 * etc/bench.pl.in (bench_fusion_parser): Remove.
693 Adjust.
694
6952008-11-26 Akim Demaille <demaille@gostai.com>
696
697 Use yy* consistently.
698 * data/glr.c: Now that yyrhs no longer exists as a global
699 variable, rename local "rhs" variables into "yyrhs" for
700 consistency.
701
7022008-11-25 Akim Demaille <demaille@gostai.com>
703
704 Get rid of yyrhs and yyprhs in glr.c.
705 * data/glr.c (yyrhs, yyprhs): Remove.
706 Instead, use the state stack and yystos.
707
7082008-11-25 Akim Demaille <demaille@gostai.com>
709
710 Flag glr tests.
711 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
712 as an Autotest keyword.
713
7142008-11-25 Akim Demaille <demaille@gostai.com>
715
716 Prefer TESTSUITE_FLAGS.
717 TESTSUITEFLAGS is barely readable.
718
719 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
720 for backward compatibility.
721 Use the former instead of the latter.
722
7232008-11-25 Akim Demaille <demaille@gostai.com>
724
725 Get rid of yyrhs and yyprhs in larl1.java.

730
731 Formatting changes.
732
7332008-11-25 Akim Demaille <demaille@gostai.com>
734
735 Get rid of yyrhs and yyprhs in yacc.c.
736 They were used to get the symbol types, given a rule number, when
737 displaying the top of the stack before a reduction. But the
738 symbol type is available from the state stack. This has two be
739 benefits: two tables less in the parser (making it smaller), and a
740 more consistent use of the three stacks which will help to fuse
741 them.
742
743 * data/yacc.c (yyprhs, yyrhs): Remove.
744 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
745 (yy_reduce_print): Take yyssp as argument.
746 Use it, together with yystos, to get the symbol type.
747 * tests/regression.at (Web2c Report): Remove these tables from the
748 expected output.
749
7502008-11-25 Akim Demaille <demaille@gostai.com>
751
752 b4_tables_map.
753 The point is to factor the generation of the tables across skeletons.
754 This is language dependant.
755
756 * data/c.m4 (b4_comment_): New.
757 Should be usable to define how to generate tables independently of
758 the language.
759 (b4_c_comment): New.
760 (b4_comment): Bounce to b4_c_comment.
761 Now support $2 = [PREFIX] for indentation.
762 * data/lalr1.cc (b4_table_declare): Don't output a comment if
763 there is no comment.
764 Indent it properly when there is one.
765 Output the ending semicolon.
766 (b4_table_define): Space changes.
767 Output the ending semicolon.

778 signature.
779 Move all the comments around invocations of b4_table_define into
780 the invocations itselves.
781 Move things around to have the order for declarations and
782 definitions.

936 Support parametric types.
937
938 There are two issues to handle: first scanning nested angle
939 bracket pairs to support types such as std::pair< std::string,
940 std::list<std::string> > >.
941
942 Another issue is to address idiosyncracies of C++: do not glue two
943 closing angle brackets together (otherwise it's operator>>), and
944 avoid sticking blindly a TYPE to the opening <, as it can result
945 in '<:' which is a digraph for '['.
946
947 * src/scan-gram.l (brace_level): Rename as...

962
963 Test token.prefix.
964 This is not sufficient, but we test at least that the make_SYMBOL
965 interface is not affected by token.prefix. A more general test
966 will be implemented when the support of token.prefix is generalized
967 to more skeletons.
968
969 * tests/c++.at: One more variant test, using token.prefix.

1044 It does not work, and I don't know how it was supposed to work: it

1068 It used to bounce to the version in src/Makefile.am which is now
1069 part of this very Makefile.
1070 * Makefile.am, configure.ac: Adjust.
1071 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
1072 include "..." to find files "here": we are no longer in src/, so
1073 qualify the includes with src/.
1074 * doc/Makefile.am (PREPATH): No longer include the top_builddir
1075 prefix.
1076 (.x.1): Adjust to be able to create src/foo from the top level
1077 Makefile, instead of going bounce to src/Makefile the creation of
1078 foo.

1132
1133 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
1134 token type.
1135 Using template buys us nothing, and makes it uselessly complex to
1136 construct a symbol. Besides, it could not be generalized to other
1137 languages, while make_FOO would work in C/Java etc.
1138

1140 (b4_symbol): Use it.
1141 (b4_symbol_constructor_declaration_)
1142 (b4_symbol_constructor_definition_): Instead of generating
1143 specializations of an overloaded template function, just generate
1144 several functions whose names are forged from the token names
1145 without the token.prefix.
1146 (b4_symbol_constructor_declarations): Generate them for all the
1147 symbols, not just by class of symbol type, now that instead of
1148 specializing a function template by the token, we generate a
1149 function named after the token.
1150 (b4_symbol_constructor_specialization_)
1151 (b4_symbol_constructor_specializations): Remove.
1152 * etc/bench.pl.in: Adjust to this new API.

1156 %define token.prefix.
1157 Provide a means to add a prefix to the name of the tokens as
1158 output in the generated files. Because of name clashes, it is
1159 good to have such a prefix such as TOK_ that protects from names
1160 such as EOF, FILE etc. But it clutters the grammar itself.
1161
1162 * data/bison.m4 (token.prefix): Empty by default.
1163 * data/c.m4 (b4_token_enum, b4_token_define): Use it.

1180 (yytoken_number_): Move into...
1181 (symbol::token): here, since that's the only use.
1182 The other one is YYPRINT which was not officially supported
1183 by lalr1.cc, and anyway it did not work since YYPRINT uses this
1184 array under a different name (yytoknum).

1203
1204 Define make_symbol in the header.
1205 To reach good performances these functions should be inlined (yet
1206 this is to measure precisely). To this end they must be available
1207 to the caller.
1208
1209 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
1210 location_type with the class name.
1211 Since will now be output in the header, declare "inline".
1212 No longer use b4_symbol_constructor_specializations, but
1213 b4_symbol_constructor_definitions in the header.
1214 Don't call it in the *.cc file.
1215
12162008-11-13 Akim Demaille <demaille@gostai.com>
1217
1218 Define yytranslate in the header for lex_symbol.
1219 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
1220 into the header file when using %define lex_symbol.
1221 (yytranslate_): Declare inline.
1222
12232008-11-13 Akim Demaille <demaille@gostai.com>
1224
1225 Define the constructors of symbol_type in
1226 b4_symbol_constructor_definitions.
1227 The constructors are called by the make_symbol functions, which a
1228 forthcoming patch will move elsewhere. Hence the interest of
1229 putting them together.
1230
1231 The stack_symbol_type does not need to be moved, it is used only
1232 by the parser.
1233
1234 * data/lalr1.cc: Move symbol_type and symbol_base_type
1235 constructors into...
1236 (b4_symbol_constructor_definitions): here.
1237 Adjust.
1238
12392008-11-13 Akim Demaille <demaille@gostai.com>
1240
1241 Make it easier to move the definition of yytranslate_.
1242 Forthcoming changes will make it possible to use yytranslate_
1243 from outside the parser implementation file.
1244
1245 * data/lalr1.cc (b4_yytranslate_definition): New.
1246 Use it.
1247
12482008-11-13 Akim Demaille <demaille@gostai.com>
1249
1250 Remove useless class specification.
1251 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
1252 to refer to the class name to use a type defined by the class for
1253 arguments of member functions.
1254
12552008-11-13 Akim Demaille <demaille@gostai.com>
1256
1257 Finer input type for yytranslate.
1258 This patch is debatable: the tradition expects yylex to return an int
1259 which happens to correspond to token_number (which is an enum). This
1260 allows for instance to return characters (such as '*' etc.). But this
1261 goes against the stronger typing I am trying to have with the new
1262 lex interface which return a symbol_type. So in this case, feed
1263 yytranslate_ with a token_type.
1264
1265 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
1266 expect a token_type.
1267
12682008-11-13 Akim Demaille <demaille@gostai.com>
1269
1270 Honor lex-params in %define lex_symbol mode.

1279
12802008-11-13 Akim Demaille <demaille@gostai.com>
1281
1282 Use b4_type_names for the union type.
1283 The union used to compute the size of the variant used to iterate
1284 over the type of all the symbols, with a lot of redundancy. Now
1285 iterate over the lists of symbols having the same type-name.
1286
1287 * data/lalr1.cc (b4_char_sizeof_): New.
1288 (b4_char_sizeof): Use it.
1289 Adjust to be called with a list of numbers instead of a single
1290 number.
1291 Adjust its caller for new-line issues.
1292
12932008-11-13 Akim Demaille <demaille@gostai.com>
1294
1295 Define the "identifier" of a symbol.
1296 Symbols may have several string representations, for instance if
1297 they have an alias. What I call its "id" is a string that can be
1298 used as an identifier. May not exist.
1299
1300 Currently the symbols which have the "tag_is_id" flag set are
1301 those that don't have an alias. Look harder for the id.
1302
1303 * src/output.c (is_identifier): Move to...
1304 * src/symtab.c (is_identifier): here.
1305 * src/symtab.h, src/symtab.c (symbol_id_get): New.
1306 * src/output.c (symbol_definitions_output): Use it to define "id"
1307 and "has_id".
1308 Remove the definition of "tag_is_id".
1309 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
1310 "tag_is_id" were used to produce code.
1311 We still use "tag" for documentation.

1321 without locations with lalr1.cc.
1322 Test these cases.
1323 * tests/output.at: Check lalr1.cc with and without location
1324 support.

1441 make_symbol provides a means to construct a full symbol (kind,
1442 value, location) in a single shot. It is meant to be a Symbol
1443 constructor, parameterized by the symbol kind so that overloading
1444 would prevent incorrect kind/value pairs. Unfortunately
1445 parameterized constructors do not work well in C++ (unless the
1446 parameter also appears as an argument, which is not acceptable),
1447 hence the use of a function instead of a constructor.
1448
1449 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1450 (b4_symbol_constructor_declarations)
1451 (b4_symbol_constructor_specialization_)
1452 (b4_symbol_constructor_specializations)
1453 (b4_symbol_constructor_definition_)
1454 (b4_symbol_constructor_definitions): New.
1455 Use them where appropriate to generate declaration, declaration of
1456 the specializations, and implementations of the templated
1457 overloaded function "make_symbol".
1458 (variant::variant): Always define a default ctor.
1459 Also provide a copy ctor.
1460 (symbol_base_type, symbol_type): New ctor overloads for value-less
1461 symbols.
1462 (symbol_type): Now public, so that functions such as yylex can use
1463 it.

1466
1467 Inform m4 whether a tag is a valid id.
1468 * src/output.c (is_identifier): New.
1469 (symbol_definitions_output): Use it to define tag_is_id.
1470 But maybe this should be done at m4 level?
1471
14722008-11-11 Akim Demaille <demaille@gostai.com>
1473
1474 Test 214 was failing: it greps with a pattern containing [ ]*
1475 which obviously meant to catch spaces and tabs, but contained only
1476 spaces. Tabulations in sources are a nuisance, so to simplify the
1477 matter, get rid of all the tabulations in the Java sources. The
1478 other skeletons will be treated equally later.
1479
1480 * data/java.m4, data/lalr1.java: Untabify.
1481 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1482 tabulations are no longer generated.

1610 * data/lalr1.cc: Don't indent before rule and symbol actions, as
1611 they can be empty, and anyway this incorrectly indents the first

16602008-11-10 Akim Demaille <demaille@gostai.com>
1661
1662 Change the handling of the symbols in the skeletons.
1663 Before we were using tables which lines were the symbols and which
1664 columns were things like number, tag, type-name etc. It is was
1665 difficult to extend: each time a column was added, all the numbers had
1666 to be updated (you asked for colon $2, not for "tag"). Also, it was
1667 hard to filter these tables when only a subset of the symbols (say the
1668 tokens, or the nterms, or the tokens that have and external number
1669 *and* a type-name) was of interest.
1670
1671 Now instead of monolithic tables, we define one macro per cell. For
1672 instance "b4_symbol(0, tag)" is a macro name which contents is
1673 self-decriptive. The macro "b4_symbol" provides easier access to
1674 these cells.
1675
1676 * src/output.c (type_names_output): Remove.
1677 (symbol_numbers_output, symbol_definitions_output): New.
1678 (muscles_output): Call them.
1679 (prepare_symbols): Define b4_symbols_number.

1721
1722 Add %precedence support.
1723 Unfortunately it is not possible to reuse the %prec directive. This
1724 is because to please POSIX, we do not require to end the rules with a
1725 semicolon. As a result,
1726
1727 foo: bar %prec baz
1728
1729 is ambiguous: either a rule which precedence is that of baz, or a rule,
1730 and then a declaration of the precedence of the token baz.
1731

1733 (Precedence Only): New.

19902008-11-07 Akim Demaille <demaille@gostai.com>
1991
1992 Add "%define assert" to variants.
1993 This is used to help the user catch cases where some value gets
1994 ovewritten by a new one. This should not happen, as this will
1995 probably leak.
1996
1997 Unfortunately this uncovered a bug in the C++ parser itself: the
1998 lookahead value was not destroyed between two calls to yylex. For
1999 instance if the previous lookahead was a std::string, and then an int,
2000 then the value of the std::string was correctly taken (i.e., the
2001 lookahead was now an empty string), but std::string structure itself
2002 was not reclaimed.
2003
2004 This is now done in variant::build(other&) (which is used to take the
2005 value of the lookahead): other is not only stolen from its value, it
2006 is also destroyed. This incurs a new performance penalty of a few
2007 percent, and union becomes faster again.
2008
2009 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
2010 (b4_variant_if): New.

2287
2288 Fuse the three stacks into a single one.
2289
2290 In order to make it easy to perform benchmarks to ensure that
2291 there are no performance loss, lalr1.cc is forked into
2292 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2293 lalr1.cc.
2294
2295 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2296 exercized by the test suite, the user must install a symbolic link
2297 from lalr1.cc to it.
2298
2299 Instead of having three stacks (state, value, location), use a
2300 stack of triples. This considerably simplifies the code (and it
2301 will be easier not to require locations as currently does the C++
2302 parser), and also gives a 10% speedup according to
2303 etc/bench (probably mainly since memory allocation is done once
2304 instead of three times).
2305
2306 Another motivation is to make it easier to destruct properly
2307 semantic values: now that they are bound to their state (hence
2308 symbol type) it will be easier to call the appropriate destructor.
2309
2310 These changes should probably benefit the C parser too.
2311
2312 * data/lalr1.cc: Copy as...
2313 * data/lalr1-fusion.cc: this new file.
2314 (b4_rhs_value, b4_rhs_location): New definitions overriding those
2315 from c++.m4.
2316 (state_stack_type, semantic_stack_type, location_stack_type)
2317 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
2318 (data_type, stack_type, yystack_): New.
2319 (YYLLOC_DEFAULT, yypush_): Adjust.
2320 (yyerror_range): Now based on data_type, not location_type.
2321
23222008-11-03 Akim Demaille <demaille@gostai.com>
2323
2324 Push the state, value, and location at the same time.
2325 This is needed to prepare a forthcoming patch that fuses the three
2326 stacks into one.
2327
2328 * data/lalr1.cc (parser::yypush_): New.
2329 (parser::yynewstate): Change the semantics: instead of arriving to
2330 this label when value and location have been pushed, but yystate
2331 is to be pushed on the state stack, now the three of them must
2332 have been pushed before. yystate still must be the new state.
2333 This allows to use yypush_ everywhere instead of individual
2334 handling of the stacks.
2335
23362008-11-03 Akim Demaille <demaille@gostai.com>
2337

2340 definition to use references instead of pointers.
2341 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
2342 Take the value and location as references.
2343 Adjust callers.

2354
2355 Use variants to support objects as semantic values.
2356 This patch was inspired by work by Michiel De Wilde. But he used
2357 Boost variants which (i) requires Boost on the user side, (ii) is
2358 slow, and (iii) has useless overhead (the parser knows the type of
2359 the semantic value there is no reason to duplicate this
2360 information as Boost.Variants do).
2361
2362 This implementation reserves a buffer large enough to store the
2363 largest objects. yy::variant implements this buffer. It was
2364 implemented with Quentin Hocquet.
2365
2366 * src/output.c (type_names_output): New.
2367 (output_skeleton): Invoke it.
2368 * data/c++.m4 (b4_variant_if): New.
2369 (b4_symbol_value): If needed, provide a definition for variants.

2371 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
2372 (b4_char_sizeof, yy::variant): New.
2373 (parser::parse): If variants are requested, define
2374 parser::union_type, parser::variant, change the definition of
2375 semantic_type, construct $$ before running the user action instead
2376 of performing a default $$ = $1.
2377 * examples/variant.yy: New.

2497 Always put auxiliary code files in the same dir as other output files.
2498 * src/files.c (compute_file_name_parts): When the user specifies
2499 --output but not --file-prefix, extract the directory prefix from the

2737
2738 Fix dependence on computed configure variables.
2739 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not

2768 but, in general, we still can't be sure of our next release name.
2769 * bootstrap: Add a quick hack to remove from .gitignore the
2770 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile

2809 .cvsignore files are maintained even though Bison developers run

2812 unneeded by Bison.
2813 (gnulib): Add.
2814 * .gitignore (/*.patch *.log log patches applied): Remove, broken and

28952008-04-23 Eric Blake <ebb9@byu.net>
2896
2897 Revert prior patch, by working around autoconf regression.
2898 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
2899 ("Output file name: ("): Uncomment test.
2900 ("Output file name: )"): Likewise.
2901 Based on an idea from Noah Misch.
2902
29032008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2904
2905 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
2906 2.61. Reported by Juan Manuel Guerrero at
2907 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
2908 * tests/output.at ("Output file name: ("): Comment out test case for
2909 now.
2910 ("Output file name: )"): Likewise.
2911
29122008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

2915 succeeds.
2916
29172008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2918
2919 Update to the current gnulib CVS repository, and fix trigraph handling
2920 in Bison.
2921 * bootstrap: Update gnulib CVS repository URL.
2922 (symlink_to_dir): Encapsulate the code that guarantees the destination
2923 directory exists into...
2924 (check_dst_dir): ... this new function, and...
2925 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
2926 fail when copying files into lib/uniwidth/.
2927 * src/output.c (prepare_symbols): When writing yytname muscles, where
2928 symbol names will be encoded in C-string literals, tell quotearg to
2929 escape trigraphs. This used to be the default in gnulib.
2930 * tests/regression.at (Token definitions): Because of the change in
2931 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2932 escapes trigraphs in symbol names. Thus, yytname no longer has
2933 trigraphs unnecessarily doubly escaped. Update test case output.
2934 Extend test case to be sure Bison's own error messages will no longer
2935 have trigraphs in symbol names unnecessarily escaped once.

2952 arguments. Use brackets to indicate optional arguments.
2953 * src/getargs.c (usage): Explain the relationship between arguments of
2954 long and short options more completely. Document --defines and -d
2955 separately since the former takes an argument but, for POSIX Yacc, the

2973 * build-aux/cross-options.pl: Use /x to make the regexp easier to
2974 understand.
2975 Fix the handling of $opt which resulted in all the argument to be
2976 considered as optional.

3553 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a `&#10;'

3569 * data/xslt/xml2text.xsl: Import bison.xsl.

3596 the comma that follows it.

3599

3607 the above macros.
3608 * data/lalr1.cc (b4_namespace): Likewise.
3609 * data/location.cc (b4_namespace): Likewise.
3610 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
3611 inside a new table in the general %define entry. Document `%define
3612 namespace' there as well. Point the %name-prefix entry to it since it
3613 explains it more completely in the case of C++.
3614 (C++ Bison Interface): Mention `%define namespace' instead of
3615 %name-prefix.
3616 (Table of Symbols): Remove the `%define push_pull' entry. The %define
3617 entry suffices.
3618 * tests/c++.at (Relative namespace references): New test case.
3619 (Absolute namespace references): New test case.
3620 (Syntactically invalid namespace references): New test case.

3651 (Complaining during macro argument expansion): Extend to test
3652 b4_percent_define_get_loc and b4_percent_define_get_syncline errors.
3653
36542007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
3655
3656 Fix some error-reporting macro bugs.
3657 * data/bison.m4 (b4_cat): New.
3658 (b4_error, b4_error_at): Use b4_cat to send error directives directly
3659 to stdout so they don't become arguments to other macros. Update
3660 comments and add examples.
3661 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
3662 add examples.
3663 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
3664 after printing the error directive so that M4 doesn't report subsequent
3665 problems that are induced by this problem.
3666 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
3667 instead of just in them. Recognize @\n in both places. Both expand to
3668 the empty string. Needed by b4_cat.
3669 * tests/skeletons.at (Complaining during macro argument expansion):
3670 New test case.
3671 (Fatal errors make M4 exit immediately): New test case.
3672
36732007-10-04 Joel E. Denny <jdenny@ces.clemson.edu>
3674
3675 Implement --print-datadir.

3677 (PRINT_DATADIR_OPTION): New anonymous enum member.
3678 (long_options): Add entry for it.
3679 (getargs): Add case for it calling compute_pkgdatadir.
3680 * src/output.c (output_skeleton): Encapsulate data directory
3681 computation from here...
3682 (prepare): ... and from here...
3683 (compute_pkgdatadir): ... into this new function.
3684 * src/output.h (compute_pkgdatadir): Prototype.
3685
36862007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>
3687
3688 * src/print-xml.c (escape_bufs): New static global variable
3689 replacing...
3690 (xml_escape_n): ... the static local variable buf here.
3691 (print_xml): Free memory for escape_bufs.
3692 * src/reduce.c (reduce_xml): XML-escape terminal symbol tags.
3693
36942007-09-25 Joel E. Denny <jdenny@ces.clemson.edu>
3695
3696 Replace `%push-parser' and `%push-pull-parser' with
3697 `%define push_pull "push"' and `%define push_pull "both"'.
3698 `%define push_pull "pull"' is the default.
3699 * doc/bison.texinfo (Push Decl, Push Parser Function,
3700 Pull Parser Function, Parser Create Function, Parser Delete Function):
3701 Update declarations.
3702 (Decl Summary, Table of Symbols): Replace %push-parser and
3703 %push-pull-parser entries with a %define push_pull entry.
3704 * data/bison.m4 (b4_percent_define_check_values): New macro.
3705 (b4_pull_if, b4_push_if, b4_use_push_for_pull_if): Move these
3706 definitions...
3707 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
3708 definitions...
3709 * data/push.c: ... to here and compute them from the value of the
3710 %define variable push_pull.
3711 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
3712 parsing requests here...
3713 * data/yacc.c: ... hack this to switch to push.c any time
3714 b4_use_push_pull_flag or the %define variable push_pull is set. This
3715 will go away when we mv push.c yacc.c.
3716 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
3717 push parsing is not supported since unused %define variables are
3718 reported anyway.
3719 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
3720 * src/muscle_tab.h (muscle_percent_define_check_values): Update
3721 comments for consistency with b4_percent_define_check_values.

3731 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Update
3732 declaration.
3733 (Push Parsing: Multiple impure instances): Update declaration.
3734 (Push Parsing: Unsupported Skeletons): New test case.
3735 * tests/torture.at (Exploding the Stack Size with Alloca): Update
3736 declaration.
3737 (Exploding the Stack Size with Malloc): Update declaration.
3738
37392007-09-24 Wojciech Polak <polak@gnu.org>
3740

3752 Problem reported by Wojciech Polak.
3753 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.
3754 (xml_printf): Undo change I made on 21 September; that is,
3755 indent 2 spaces, not 1.
3756
37572007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
3758
3759 Pacify ./configure --enable-gcc-warnings.
3760 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
3761 `char const *' instead of `char *'.
3762 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
3763 local variable `sep'.
3764
37652007-09-21 Paul Eggert <eggert@cs.ucla.edu>
3766
3767 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
3768 elsewhere.
3769 * src/print-xml.c: Prefer "const" after types; that's more consistent.
3770 (xml_printf): Indent just 1 space for level.
3771 (e_char, xlate_char): Remove.
3772 (xml_escape_string): Rewrite to avoid undefined behavior (used
3773 storage that was freed from the stack).
3774 (xml_escape_n): Don't bother checking for subscript error.
3775
37762007-09-21 Wojciech Polak <polak@gnu.org>
3777

3825 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
3826 Bruno Haible <bruno@clisp.org>
3827
3828 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists

3830
38312007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>
3832
3833 Spell "boolean" as "Boolean". Reported by Akim Demaille.

3835 * doc/bison.texinfo (Decl Summary): Fix.
3836 * src/muscle_tab.c (muscle_percent_define_flag_if): Fix complaint.
3837 * tests/input.at (Boolean %define variables): Update output.
3838 * tests/skeletons.at (%define boolean variables: invalid skeleton
3839 defaults): Rename to...

3841 update output.
3842
38432007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
3844
3845 In impure push mode, don't allow more than one yypstate to be allocated
3846 since multiple impure parsers would corrupt yynerrs.
3847 * data/push.c (yypstate_allocated): New static global variable
3848 initialized to 0.
3849 (yypull_parse): If yypstate_new returns 0, don't report it as memory
3850 exhaustion if yypstate_allocated is 1, but still return 2.
3851 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
3852 already 1. Otherwise, set it to 1.
3853 (yypstate_delete): Set it to 0.
3854 * tests/push.at (Push Parsing: Multiple impure instances): New test
3855 case.
3856

3858
3859 * doc/bison.texinfo (Push Decl): Document the push parser.
3860 (Table of Symbols): Ditto.
3861 (Pure Decl): Ditto.
3862 (Decl Summary): Ditto.
3863 (Multiple Parsers, Push Parser Function, Pull Parser Function,
3864 Parser Create Function, Parser Delete Function):
3865 Add new push parser symbols.
3866 (Table of Symbols): Document push-parser, push-pull-parser,
3867 yypush_parse, yypull_parse, yypstate_new and yypstate_delete.
3868
38692007-08-15 Paul Eggert <eggert@cs.ucla.edu>

3925
39262007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3927
3928 Get rid of broken %no-parser, -n, and --no-parser implementation and
3929 documentation.
3930 * TODO: Don't mention them.
3931 * doc/bison.1: Likewise.
3932 * doc/bison.texinfo (Decl Summary): Likewise.
3933 (Bison Options): Likewise.
3934 (Option Cross Key): Likewise.
3935 * src/getargs.c (no_parser_flag): Remove global variable.
3936 (usage): Don't print description of -n and --no-parser.
3937 (long_options): Remove --no-parser entry here.
3938 (getargs): Remove -n case in the switch here.
3939 * src/getargs.h (no_parser_flag): Remove extern.
3940 * tests/regression.at (Web2c Actions): Remove comment that mentions
3941 --no-parser.
3942
39432007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3944
3945 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
3946 name user variables starting with `yy'. Just pass NULL instead of a
3947 dummy local &yylval to yypush_parse.
3948 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
3949 starting with `yy'.
3950
39512007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
3952
3953 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
3954 true since it's then always used regardless of whether yyoverflow is
3955 defined. Reported by Christian Burger at
3956 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
3957 * THANKS: Add Christian Burger.
3958
3959 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3960 node names: say "Decl Summary" not "Bison Declaration Summary".
3961
39622007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
3963
3964 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
3965 determine whether this function has already complained about an invalid
3966 value for a %define boolean variable, don't check whether Bison has
3967 ever examined the value. As written, the check was a tautology.
3968 Instead, record and check for this complaint using a separate muscle.
3969
39702007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
3971
3972 Fix push parsing memory leak reported by Brandon Lucia at
3973 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
3974 * THANKS: Add Brandon Lucia.
3975 * data/push.c (yypstate_delete): Free the stack if it was reallocated
3976 but the parse never completed and thus freed it.
3977 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
3978 * tests/testsuite.at: Include push.at.
3979 * test/push.at: New.
3980 (Push Parsing: Memory Leak for Early Deletion): New test case.
3981
39822007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3983
3984 Improve handling of multiple S/R conflicts in the same state and of S/R
3985 conflicts involving multiple reductions.
3986 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3987 set for a state here or Bison will abort if it is reassigned on a
3988 later conflicted reduction in the same state.
3989 Similarly, don't finalize and assign the solved conflicts report here
3990 or it will be lost if it is reassigned on a later conflicted reduction
3991 in the same state.
3992 (set_conflicts): Instead, assign them both here after all S/R conflicts
3993 in the state have been fully examined.
3994 * src/print.c (shift_set): Rename to...
3995 (no_reduce_set): ... this.
3996 (print_reductions): Update for rename, and add %nonassoc error action
3997 tokens to no_reduce_set so that, when printing the first remaining
3998 reduction on an error action token, the reduction is enclosed in
3999 brackets.
4000 (print_results): Update for rename.
4001 * tests/conflicts.at (Solved conflicts report for multiple reductions
4002 in a state): New test case.
4003 (%nonassoc error actions for multiple reductions in a state): New test
4004 case.
4005
4006 * src/main.c (main): Don't depend on C99 features.
4007
40082007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
4009
4010 * build-aux/.cvsignore: Add compile.
4011 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
4012 uniwidth.
4013
40142007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
4015
4016 * bootstrap (slurp): Create target directories that don't exist.
4017 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
4018
40192007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4020
4021 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
4022 than item number.
4023 * closure.c (closure): Likewise.
4024 * state.h (reductions): Comment sorting of rules.
4025 (state): Comment sorting of items.
4026
40272007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
4028
4029 Fix C++ test cases after recent Gnulib changes. Discussed starting at
4030 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
4031 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
4032 definition in order to avoid Gnulib headers since we don't use config.h
4033 here.
4034 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
4035 rather than AT_DATA so that config.h is included.
4036
40372007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
4038
4039 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
4040 instead of fprintf. Guard these functions with #if YYDEBUG instead of
4041 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
4042 and so that YYFPRINTF is guaranteed to be defined here.
4043
40442007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4045
4046 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
4047 with...
4048 (muscle_percent_define_check_values): ... this more helpful function.
4049 Again, it's not used yet, but it will be.
4050 * src/muscle_tab.h: Likewise.
4051
4052 Improve some comments in parser table construction.
4053 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
4054 (generate_states): Don't mention ruleset, which is internal to closure.
4055 * src/closure.c (closure): Explain sorting of core and itemset, which
4056 is required for this function to behave correctly.
4057 * src/closure.h (closure): Mention sorting.
4058
40592007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
4060
4061 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4062 move the check for disabled transitions to an aver since conflict
4063 resolution hasn't happened yet.
4064
4065 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4066 labels a state as inconsistent just because it has error transitions.
4067 The original form of this check appeared in revision 1.1 of lalr.c,
4068 which was committed on 1991-12-21. Now (at least), changing the
4069 consistency label on such a state appears to have no useful effect in
4070 any of the places it is examined, which I enumerate below. The key
4071 point to understanding each item in this enumeration is that a state
4072 with an error transition is labelled consistent in the first place only
4073 if it has no rules, so the check cannot matter for states that have
4074 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4075 to try to identify its conflicts, and a state must have *rules* to have
4076 conflicts. (2) Labelling a state as inconsistent will affect how
4077 action_row sets the default *rule* for the state. (3) Labelling a
4078 state as inconsistent will cause build_relations to add lookback edges
4079 to *rules* in that state.
4080 * src/state.h (struct state): Word the comment for member consistent
4081 more carefully.
4082
40832007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>

4090 (state_remove_unreachable_states): Fix for-loop.
4091
4092 Don't widen struct state with member reachable just to temporarily
4093 record reachability. Instead, use a local bitset.
4094 * src/state.h (struct state): Remove member.
4095 * src/state.c (state_new): Don't initialize it.
4096 (state_mark_reachable_states): Rename to...
4097 (state_record_reachable_states): ... this, and use bitset.
4098 (state_remove_unreachable_states): Use bitset.

4103 that the yacc script isn't corrupt. Reported by Hans Aberg at
4104 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
4105
4106 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
4107 the case of pure parsers. Reported by Frans Englich at
4108 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
4109 * THANKS: Add Frans Englich.
4110
4111 * NEWS (2.3a+): In the %code entry, reference section `Bison

4118
4119 Extend the front-end API for %define variables to more completely
4120 mirror the back-end. This will be useful in the future.

4149 If conflict resolution makes states unreachable, remove those states,
4150 report rules that are then unused, and don't report conflicts in those
4151 states.

4176 used in the comments.
4177 (closure): Update for rename.
4178 * src/closure.h (nritemset): Update extern to...
4179 (nitemset): ... this.

41852007-04-04 Paul Eggert <eggert@cs.ucla.edu>
4186
4187 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
4188 still sticks to ASCII. Sorry!
4189

42392007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4240
4241 DJGPP spefic issue. Inhibit the use of disallowed characters for
4242 file name genertion on Win98, WinXP, etc. These are |<>":?*\

4262 %define and %code directives.
4263
4264 Make it easy to share %define boolean variables between the front-end
4265 and back-end. Though not used yet, this will be useful in the future.
4266 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
4267 Bison uses of names rather than just skeleton uses of names.
4268 (b4_percent_define_get, b4_percent_define_ifdef): Rename

4281 * data/bison.m4 (b4_percent_define_flag_if): Read
4282 b4_percent_define_loc(VARIABLE) to report the location of an invalid
4283 value for VARIABLE.
4284 (b4_percent_define_default): Save a special location in

4286 must later be reported as invalid.
4287 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
4288 functions.
4289 (muscle_percent_define_insert): Record the location of VARIABLE in
4290 muscle percent_define_loc(VARIABLE), and use it to report the previous
4291 location for a redefinition.
4292 (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
4293 (muscle_percent_define_default): Update like b4_percent_define_default.
4294 (muscle_grow_user_name_list): Rename to...

4303
4304 * src/print.c (lookahead_set, state_default_rule): Remove.
4305 (print_reductions): Replace state_default_rule invocation with
4306 equivalent use of yydefact, which was computed in token_actions in
4307 tables.c.
4308 (print_results): Don't allocate lookahead_set.
4309
43102007-02-27 Paolo Bonzini <bonzini@gnu.org>
4311
4312 * data/lalr1.java: Prefix all private members with yy.
4313
43142007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
4315
4316 Use YYFPRINTF instead of fprintf where appropriate. Reported by
4317 Sebastien Fricker at
4318 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
4319 * THANKS: Add Sebastien Fricker.
4320 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
4321 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must

4325
4326 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.

4333
43342007-02-11 Paul Eggert <eggert@cs.ucla.edu>
4335
4336 Undo my 2007-02-07 change, switching back to the c-strcase module
4337 introduced in the 2007-02-03 change. Bruno Haible reported that
4338 the 2007-02-07 change would be dangerous in Turkish if we add a
4339 language whose name contains "i", since "i" is not lowercase "I"
4340 in Turkish.
4341 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
4342 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
4343 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
4344 * m4/.cvsignore: Remove strcase.m4.
4345 * src/getargs.c: Revert 2007-02-07 change, as follows.
4346 Include c-strcase.h.
4347 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
4348
43492007-02-11 Bruno Haible <bruno@clisp.org>
4350
4351 Enable the Java related testsuite tests when the only Java compiler
4352 found is a gcj < 4.3. Discussed at
4353 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
4354 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
4355
43562007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
4357
4358 * data/Makefile.am: Update copyright date.
4359 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
4360 yypstate_new returns NULL.
4361 (yypstate_new): Return NULL if malloc does.
4362 * src/reader.c (packgram): Move translation of rule actions from the
4363 beginning of packgram to...
4364 (check_and_convert_grammar): ... here right before packgram is invoked
4365 so it's easier to write more complete comments, and remove redundant
4366 code.
4367
43682007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
4369
4370 As in semantic actions, make @$ in %initial-action, %destructor, and
4371 %printer imply %locations.
4372 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
4373 scanning @$.
4374 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
4375 (@$ in %initial-action implies %locations,
4376 @$ in %destructor implies %locations,
4377 @$ in %printer implies %locations): ... these new test cases.
4378
43792007-02-07 Paul Eggert <eggert@cs.ucla.edu>
4380
4381 Undo most of the 2007-02-03 change, switching to the strcase module
4382 now that gnulib strcase has been fixed.
4383 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
4384 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
4385 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
4386 * m4/.cvsignore: Add strcase.m4.
4387 * src/getargs.c: Revert 2007-02-03 change, as follows.
4388 Don't include c-strcase.h.
4389 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4390 strcasecmp has "unspecified behavior" outside the POSIX locale,
4391 but it works fine in practice if at least one argument is ASCII,
4392 as is the case in Bison.
4393
43942007-02-07 Paolo Bonzini <bonzini@gnu.org>
4395
4396 * tests/java.at: Skip tests if only one of javac/java is present.
4397 Reported by Joel E. Denny.
4398 * tests/atlocal.in: Adjust copyright years.
4399
44002007-02-05 Paolo Bonzini <bonzini@gnu.org>
4401
4402 * data/lalr1.java (Stack): Work around old verifiers that disallow
4403 access to the private fields of an inner class, from the outer class.
4404 We can make Stack's fields public because user code doesn't have access
4405 to the instance of Stack used by parse(). Reported by Paul Eggert.
4406
44072007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4408
4409 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4410 the right spot for these files?
4411 * bootstrap.conf (gnulib_modules): Add c-strcase.
4412 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4413 c-strncasecmp.c.
4414 * src/getargs.c: Include c-strcase.h.
4415 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4416 to avoid unspecified behavior.
4417
44182007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
4419
4420 * doc/bison.texinfo (Decl Summary): Correct typo.
4421
44222007-01-30 Paolo Bonzini <bonzini@gnu.org>
4423
4424 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
4425 Complain if the value does not match empty, "true" or "false".
4426 * data/c++.m4: Adjust default definitions of %define variables.
4427 * data/java.m4: Adjust default definitions of %define variables.
4428 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
4429 to above behavior.
4430 * tests/input.at (Boolean %define variables): Test new behavior.
4431
44322007-01-29 Paolo Bonzini <bonzini@gnu.org>
4433
4434 * NEWS: Mention java.
4435 * TODO: Remove things that are done.
4436 * bootstrap.conf: Add javacomp-script and javaexec-script.
4437 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
4438
4439 * data/Makefile.am: Add new files.
4440 * data/java-skel.m4: New.
4441 * data/java.m4: New.
4442 * data/lalr1.java: New.
4443
4444 * doc/bison.texinfo: Put "A Complete C++ Example" under
4445 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
4446 under Other Languages.
4447
4448 * src/getargs.c (valid_languages): Add Java.
4449 * src/getargs.h (struct bison_language): Update size of string fields.
4450
4451 * tests/Makefile.am: Add java.at.
4452 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
4453 * tests/java.at: New.
4454 * tests/testsuite.at: Include it.

4457
4458 Clean up.
4459 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4460 at_directive_argv arguments so these no longer have to be global
4461 variables. Also, update the implementation for the following changes.
4462 (fail_for_at_directive_too_many_args,
4463 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4464 (at_directive_name): Remove as at_directive_argv[0] will be used for
4465 this now.
4466 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4467 for the directive name.
4468 (at_directive_argc, at_directive_argv): Make these local within
4469 skel_lex instead of global.
4470 (INITIAL): Update directive start action for above changes.
4471 (SC_AT_DIRECTIVE_ARG): Rename to...
4472 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4473 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4474 (scan_skel): Move yylex_destroy to...
4475 (skel_scanner_free): ... here.
4476 * tests/skeletons.at (installed skeleton file name): Rename to...
4477 (installed skeleton file names): ... this.
4478
44792007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4480
4481 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4482 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4483 Summary" not "Directives".
4484 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4485 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4486 since the former is now the more complete one.
4487 (Prologue Alternatives): Likewise and do the same for %defines.
4488 (Table of Symbols): Add summary of %code, add summary of %define, and
4489 move full %code documentation to...
4490 (Decl Summary): ... here for consistency with other entries in these
4491 sections.
4492 Move %define entry in order to keep this list alphabetized.
4493 Reword %define entry a little to put less emphasis on the skeleton
4494 concept, which most users shouldn't have to think about.
4495
44962007-01-26 Paul Eggert <eggert@cs.ucla.edu>
4497
4498 Adjust to recent gnulib changes.
4499 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
4500 Add string.h, string_.h, unistd_.h, wchar_.h.
4501 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
4502 * src/system.h: Don't include <stpcpy.h>; this is now done by
4503 <string.h>.
4504
45052007-01-23 Paolo Bonzini <bonzini@gnu.org>
4506
4507 Simplify implementation of unqualified %code, implement macros for
4508 uniform treatment of boolean %define flags. Document %define.
4509 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
4510 b4_percent_code_ifdef): New.
4511 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
4512 * data/c++.m4: Define default value for global_tokens_and_yystype.
4513 * data/glr.cc: Likewise.
4514 * data/location.cc: Use b4_percent_define_flag_if.
4515
4516 * doc/bison.texinfo (Decl Summary): Document %define.
4517
4518 * src/parse-gram.y (Unqualified %code): Change muscle name to
4519 b4_percent_code().
4520 (content.opt): Default to empty.
4521
45222007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4523
4524 Implement support for relative and absolute skeleton file names.
4525 Discussed starting at
4526 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
4527 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
4528 (Bison Options): Document in --skeleton entry.
4529 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
4530 full_skeleton can't necessarily hold all of pkgdatadir.
4531 If the specified skeleton file name contains a `/', don't prepend
4532 pkgdatadir.
4533 * src/parse-gram.y (prologue_declaration): If the specified skeleton
4534 file name contains a `/', prepend the grammar file directory.
4535 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
4536 * skeletons.at: New file.
4537 (relative skeleton file names): New test case.
4538 (installed skeleton file names): New test case.
4539 * tests/testsuite.at: Include skeletons.at.
4540
4541 * bootstrap: Update copyright to 2007.
4542
45432007-01-17 Paolo Bonzini <bonzini@gnu.org>
4544
4545 * bootstrap: Remove occurrences of .#bootmp from the files.
4546
45472007-01-17 Akim Demaille <akim@epita.fr>
4548
4549 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
4550 nonterminals.
4551 Use per-type %printer.
4552
45532007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4554
4555 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

4562
45632007-01-16 Akim Demaille <akim@epita.fr>
4564
4565 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
4566 error code.
4567 (Calc++ Scanner): Exit with failure if we can't open the input
4568 file.
4569 Accept "-" standing for stdin.
4570 (Calc++ Top Level): Print the result only if the parsing was
4571 successful.
4572
45732007-01-16 Akim Demaille <akim@epita.fr>
4574
4575 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
4576
45772007-01-15 Paolo Bonzini <bonzini@gnu.org>
4578 and Joel E. Denny <jdenny@ces.clemson.edu>
4579
4580 Clean up %define and %code implementation in M4 some. Most
4581 importantly, rename all related macros to be in the b4_percent_define
4582 and b4_percent_code namespaces. Also, complete support for `.' in
4583 %define variable names and %code qualifiers.
4584 * data/bison.m4 (b4_check_user_names): Check for special
4585 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4586 m4_foreach loops.
4587 (b4_get_percent_define, b4_get_percent_code): Rename to...
4588 (b4_percent_define_get, b4_percent_code_get): ... these.
4589 Extend documentation with examples.
4590 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4591 b4_percent_define_skeleton_variables and
4592 b4_percent_code_skeleton_qualifiers.
4593 Expect any value for the %define variable `foo' to be stored in the
4594 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4595 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4596 expect any unqualified %code blocks to be stored in a macro named
4597 `b4_percent_code_unqualified'.
4598 Use m4_indir so that %define variable names and %code qualifiers can
4599 contain `.', which is allowed by the grammar parser.
4600 (b4_percent_define_default): New macro to set a default value for a
4601 %define variable.
4602 (m4_wrap): Update wrapped code, and fix some underquoting.
4603 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4604 Expect grammar uses of %define variables and %code qualifiers to be
4605 defined in b4_percent_define_user_variables and
4606 b4_percent_code_user_qualifiers.
4607 * data/c++.m4: Use b4_percent_define_default rather than
4608 m4_define_default. Fix some underquoting. Skeleton usage of %define
4609 variable define_location_comparison now implies skeleton usage of
4610 %define variable filename_type.
4611 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4612 data/push.c, data/yacc.c: Update macro names.
4613 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
4614 muscle names.
4615
46162007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4617
4618 DJGPP specific issues.
4619
4620 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
4621 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
4622
46232007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4624
4625 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
4626 run parsers in all tests so that Valgrind is invoked during
4627 maintainer-check-valgrind.
4628 (Duplicate representation of merged trees): Free all semantic values.
4629 (Duplicated user destructor for lookahead): Likewise.
4630
46312007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4632
4633 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
4634 command-line prefix.
4635 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
4636 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
4637 miss Valgrind messages.
4638 (Exploding the Stack Size with Malloc): Likewise.
4639
46402007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4641
4642 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
4643 locals. Reported by Juan Manuel Guerrero at
4644 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
4645 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
4646 Fix some indentation also.
4647 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
4648 explaining this issue.
4649
46502007-01-09 Paolo Bonzini <bonzini@gnu.org>
4651 and Joel E. Denny <jdenny@ces.clemson.edu>
4652
4653 Simplify union and prologue handling, and escape union and lex/parse
4654 params with digraphs.
4655 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
4656 values to the empty string since these are no longer guaranteed
4657 initialized by the front-end.
4658 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
4659 braces around b4_user_stype since this is no longer done by the
4660 front-end.
4661 * src/files.c, src/files.h (pre_prologue_obstack,
4662 post_prologue_obstack): Remove.
4663 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
4664 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
4665 with digraphs. This fixes lex params and parse params.
4666 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
4667 * src/output.c (prepare): Remove muscle insertion of the prologues.
4668 (output): Remove freeing of pre_prologue_obstack and
4669 post_prologue_obstack.
4670 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
4671 than prologue_augment for prologue parsing so you don't need prologue
4672 obstacks.
4673 (grammar_declaration): For %union RHS, use `braceless' instead of
4674 "{...}" so that braces are already stripped and code is escaped with
4675 digraphs.
4676 * src/reader.c (prologue_augment): Remove.
4677 (reader): Remove initialization of pre_prologue_obstack and
4678 post_prologue_obstack.
4679 * src/reader.h (prologue_augment): Remove.
4680
4681 * data/c.m4: Remove stray parenthesis.
4682
46832007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4684
4685 Remove quotes from variables names in %define directives and from
4686 qualifiers in %code directives, and restrict the characters that are
4687 allowed in them to M4-friendly ones. For %define, continue to support
4688 the quoted form as a deprecated feature. Discussed starting at
4689 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
4690 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
4691 %code.
4692 * doc/bison.texinfo (Prologue Alternatives): Update.
4693 (Decl Summary): In %defines entry, update mention of `%code requires'
4694 and `%code provides'.
4695 (C++ Location Values): Update %define uses.
4696 (Calc++ Parser Interface): Likewise.
4697 (Calc++ Parser): Likewise, and update `%code requires' uses.
4698 (Table of Symbols): Update %code documentation.
4699 * src/parse-gram.y (prologue_declaration): For %define variables, use
4700 `variable' instead of `STRING'.
4701 (grammar_declaration): For %code qualifiers, use `ID' instead of
4702 `STRING'.
4703 (variable): New nonterminal that takes an `ID' or a `STRING'.
4704 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
4705 and %define uses.
4706 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
4707 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
4708 (%define errors): Update %define uses.
4709
47102007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4711
4712 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
4713 instead of muscle_insert for %define values so that M4-special
4714 characters are replaced with digraphs.
4715 * tests/input.at (%define errors): Extend to check weird values.
4716
47172007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4718
4719 Instead of having skeletons declare all valid %define variables and
4720 %code qualifiers, provide macros that retrieve the associated values
4721 and build these lists automatically. Thus Bison will now warn when a
4722 variable or qualifier is not used by the skeleton in the current
4723 invocation regardless of whether it might sometimes be used by that
4724 skeleton in other invocations. Also, move all %define value macros to
4725 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4726 form, which is replaced by %code.
4727 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
4728 (b4_check_user_names): ... this, and change the series of valid name
4729 arguments to a single list argument for names used in the skeleton
4730 similar to the existing list argument for names used in the grammar.
4731 Warn instead of complaining.
4732 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
4733 values and %code code, to format %code code properly, and to build
4734 lists of all %define variables and %code qualifiers used in the
4735 skeleton: b4_skeleton_percent_define_variables and
4736 b4_skeleton_percent_code_qualifiers.
4737 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
4738 Remove, and...
4739 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
4740 the skeleton names lists can finish building first. In place of
4741 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
4742 expect the lists b4_user_percent_define_variables and
4743 b4_user_percent_code_qualifiers.
4744 * data/c++.m4: Where setting default values for b4_parser_class_name,
4745 b4_location_type, b4_filename_type, b4_namespace, and
4746 b4_define_location_comparison, update their names to the
4747 b4_percent_define_ namespace.
4748 * data/glr.c: Don't use b4_check_percent_define_variables and
4749 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4750 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
4751 (b4_parser_class_name, b4_namespace): Define these using
4752 b4_get_percent_define for parser_class_name and namespace.
4753 * data/location.cc: Use b4_get_percent_define.
4754 * data/push.c: Don't use b4_check_percent_define_variables and
4755 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4756 * data/yacc.c: Likewise, and don't call m4_exit in
4757 b4_use_push_for_pull_if or m4_wrap code will never execute.
4758 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
4759 Rename to...
4760 (muscle_grow_user_name_list): ... this for consistency with the
4761 terminology used in bison.m4.
4762 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
4763 %define variable names, and rename muscle used_percent_define_variables
4764 to user_percent_define_variables.
4765 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
4766 user_percent_code_qualifiers.
4767 (content): Remove.
4768 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
4769 {CODE} form is no longer accepted.
4770 * tests/input.at (Reject bad %code qualifiers): Rename to...
4771 (Reject unused %code qualifiers): ... this, and update test output.
4772 (%define error): Update test output.
4773
47742007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
4775
4776 Check for unrecognized %define variables similar to checking for
4777 unrecognized %code qualifiers. Check for redefined %define variables.
4778 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
4779 generalizes...
4780 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
4781 (b4_check_percent_define_variables): New, also wraps it.
4782 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
4783 variables using b4_check_percent_define_variables.
4784 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
4785 all those exercised in the test suite and all those listed in the
4786 `Default values' section of c++.m4. Are there others?
4787 * data/push.c, data/yacc.c: Declare no valid %define variables.
4788 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
4789 similar to muscle_find, but it works even when the muscle stores a
4790 const value.
4791 (muscle_grow_used_name_list): New function for constructing the used
4792 name list muscles that b4_check_for_unrecognized_names requires.
4793 * src/parse-gram.y (prologue_declaration): Warn if a variable is
4794 %define'd more than once. Define the b4_used_percent_define_variables
4795 muscle with muscle_grow_used_name_list.
4796 (grammar_declaration): Abbreviate %code code with
4797 muscle_grow_used_name_list.
4798 * tests/input.at (%define errors): New.
4799
48002007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4801
4802 Provide warn_at, complain_at, and fatal_at function callbacks to the
4803 skeletons, and use this for %code qualifier complaints.
4804 * data/bison.m4 (b4_error_at): New, invoked by...
4805 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
4806 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
4807 @fatal_at(...@) directives.
4808 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
4809 qualifiers in b4_used_percent_code_qualifiers and to use
4810 b4_complain_at.
4811 * src/location.c, src/location.h (boundary_set_from_string): New global
4812 function.
4813 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
4814 function.
4815 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
4816 to b4_used_percent_code_qualifiers.
4817 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
4818 function.
4819 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
4820 (lineno): Rename to...
4821 (out_lineno): ... this so I don't misunderstand it again.
4822 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
4823 here; these newlines are in the input but not the output file.
4824 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
4825 (at_directive_perform): ... this new static function, and add handling
4826 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
4827 directives.
4828 * tests/input.at (Reject bad %code qualifiers): Update test output with
4829 locations and extend.
4830
4831 * tests/output.at (Output file name: [, Output file name: ]): Remove
4832 bogus comment about these tests failing.
4833
48342007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4835
4836 Clean up b4_check_percent_code_qualifiers a little.
4837 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
4838 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
4839 documentation and add examples.
4840 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
4841 qualifiers here.
4842
48432007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
4844
4845 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4846 unreliable -- especially when they're hidden inside another macro.
4847 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
4848 data/c.m4: Remove m4_divert(-1).
4849 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4850 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
4851 m4_divert_push(0) and m4_divert_pop(0).
4852 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
4853 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
4854 pushed and popped by m4sugar, should be first on the stack.
4855
4856 Provide warn, complain, and fatal function callbacks to the skeletons.
4857 This provides more flexibility than m4_fatal, improves the error
4858 message format, and captures messages for translation. Discussed
4859 starting at
4860 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
4861 * data/bison.m4 (b4_error): New, invoked by...
4862 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
4863 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
4864 directives. Because these M4 macros might be called when the current
4865 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
4866 the previous removal of uses of m4_divert, which caused trouble.
4867 (b4_check_percent_code_qualifiers): Use b4_complain instead of
4868 m4_fatal to report unrecognized %code qualifiers.
4869 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
4870 push parser requests.
4871 * data/glr.c: Use b4_complain instead of m4_fatal to report
4872 non-deterministic push parser requests.
4873 Update @output usage to @output(...@) form.
4874 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
4875 report missing %defines. Update @output usage to @output(...@) form.
4876 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
4877 @output(...@) form.
4878 * src/main.c (main): Invoke skel_scanner_free.
4879 * src/scan-skel.h (skel_scanner_free): Prototype new function.
4880 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
4881 obstack_for_string from flex-scanner.h.
4882 (YY_DECL): Use to declare skel_lex static.
4883 (decode_at_digraphs): Remove; now handled in the new
4884 SC_AT_DIRECTIVE_ARG start condition.
4885 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
4886 functions.
4887 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
4888 at_directive_argv): New static globals.
4889 (INITIAL): Use fail_for_invalid_at.
4890 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
4891 recognize the start of a generalized `@directive(...@)' form and
4892 start...
4893 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
4894 directive args (using the new obstack_for_string), to decode the
4895 contained @ diagraphs, and to perform the directive. It recognizes
4896 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
4897 @output(...@).
4898 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
4899 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
4900 `@,'.
4901 (scan_skel): Initialize obstack_for_string on the first call.
4902 (skel_scanner_free): New function to free obstack_for_string.
4903 * tests/input.at (Reject bad %code qualifiers): Update test output.
4904
49052007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
4906
4907 Consolidate the 4 prologue alternative directives (%code, %requires,
4908 %provides, and %code-top) into a single %code directive with an
4909 optional qualifier field. Discussed at
4910 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
4911 * NEWS (2.3a+): Rewrite the existing entry for the prologue
4912 alternatives.
4913 * doc/bison.texinfo (Prologue Alternatives): Update.
4914 (Decl Summary): Update to %code "requires" and %code "provides".
4915 (Calc++ Parser): Update to %code "requires".
4916 (Table of Symbols): Remove entries for %requires, %provides, and
4917 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
4918 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
4919 are replaced by b4_percent_code_provides and b4_percent_code_requires,
4920 which are skeleton-specific.
4921 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
4922 declare what %code qualifiers it supports and to complain if any other
4923 qualifiers were used in the grammar.
4924 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
4925 and b4_user_code([b4_percent_code_provides]) in place of
4926 b4_user_requires and b4_user_provides.
4927 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
4928 Add b4_user_code([b4_percent_code_top]) and
4929 b4_user_code([b4_percent_code]).
4930 Invoke b4_check_percent_code_qualifiers.
4931 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4932 PERCENT_REQUIRES): Remove.
4933 (grammar_declaration): Remove RHS's for %code-top, %provides, and
4934 %requires. Rewrite the %code RHS as the unqualified form defining the
4935 muscle b4_percent_code. Add another RHS for the qualified %code form,
4936 which defines muscles of the form b4_percent_code_QUALIFIER and the
4937 b4_used_percent_code_qualifiers muscle.
4938 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4939 PERCENT_REQUIRES): Remove.
4940 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
4941 %code "requires" and %code "provides".
4942 * tests/input.at (Reject bad %code qualifiers): New.
4943
49442007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4945
4946 Use the new code_props interface for destructors and printers.
4947 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
4948 printer_location members, and change the type of the destructor and
4949 printer members to code_props.
4950 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
4951 symbol_printer_get, semantic_type_destructor_set,
4952 semantic_type_printer_set, default_tagged_destructor_set,
4953 default_tagless_destructor_set, default_tagged_printer_set,
4954 default_tagless_printer_set): Use code_props in arguments and return
4955 types in place of char const * and location.
4956 (symbol_destructor_location_get, symbol_printer_location_get): Remove
4957 since the locations are now contained in the return of
4958 symbol_destructor_get and symbol_printer_get.
4959 * src/output.c (symbol_destructors_output, symbol_printers_output):
4960 Replace with...
4961 (symbol_code_props_output): ... this to eliminate duplicate code.
4962 (output_skeleton): Update to use symbol_code_props_output.
4963 * src/reader.c (symbol_should_be_used): Update use of
4964 symbol_destructor_get.
4965 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4966 Update uses of the various _destructor_set and _printer_set functions.
4967 * src/symtab.c: (default_tagged_destructor_location,
4968 default_tagless_destructor_location, default_tagged_printer_location,
4969 default_tagless_printer_location): Remove since we...
4970 (default_tagged_destructor, default_tagless_destructor,
4971 default_tagged_printer, default_tagless_printer): ... change the type
4972 of these to code_props.
4973 (symbol_new, semantic_type_new, symbol_destructor_set,
4974 semantic_type_destructor_set, symbol_destructor_get,
4975 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
4976 symbol_check_alias_consistency, default_tagged_destructor_set,
4977 default_tagless_destructor_set, default_tagged_printer_set,
4978 default_tagless_printer_set): Update.
4979 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4980 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4981 code_props members.
4982 (symbol_print): Use SYMBOL_CODE_PRINT.
4983
49842007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4985
4986 Use the new code_props interface for rule actions.
4987 * src/symlist.h (symbol_list): Replace action, action_location, and
4988 used members with a code_props action_props member.
4989 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4990 grammar_midrule_action, grammar_current_rule_merge_set,
4991 grammar_current_rule_symbol_append, packgram): Update.
4992 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4993 * src/scan-code.l (handle_action_dollar): Update.
4994 (translate_rule_action): Remove, no longer used.
4995 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4996
49972007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4998
4999 Use the new code_props interface in parse-gram.y.
5000 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
5001 Update all uses of translate_* functions to use the new code_props
5002 interface and to use gram_scanner_last_string_free and
5003 code_scanner_last_string_free where possible.
5004 (grammar_declaration): symbol_list_destructor_set and
5005 symbol_list_printer_set now perform the translation, so don't do it
5006 here. Use gram_scanner_last_string_free where possible.
5007 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
5008 translate_code): Remove, no longer used.
5009 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
5010 symbol_list_printer_set): Perform code translation here rather than
5011 depending on the caller to do so.
5012
5013 * src/symlist.h (struct symbol_list): Correct some documentation typos.
5014 * src/scan-gram.h (gram_last_string): Remove declaration.
5015 * src/scan-gram.l (last_string): Declare it static.
5016
50172007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5018
5019 Encapsulate code properties and related functionality for the various
5020 destructors, printers, and actions into a code_props structure and
5021 interface. This patch merely implements code_props in scan-code.h and
5022 scan-code.l. Future patches will rewrite other modules to use it.
5023 Discussed starting at
5024 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
5025 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
5026 consistently initialize const structs that have an empty location
5027 field.
5028 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
5029 to ensure consistency.
5030 * src/scan-code.h (code_props): New structure.
5031 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
5032 function, macro, and const global variable for initializing a
5033 code_props with no code.
5034 (code_props_plain_init, code_props_symbol_action_init,
5035 code_props_rule_action_init, code_props_translate_code): The rest of
5036 the new code_props functional interface. Among other things, the init
5037 functions set the code_props kind field so that
5038 code_props_translate_code will know whether to behave like
5039 translate_symbol_action, translate_rule_action, or translate_code.
5040 These old translate functions must remain until all other modules are
5041 updated to use the new code_props interface.
5042 (code_scanner_last_string_free): New function similar to
5043 gram_scanner_last_string_free.
5044 (code_scanner_free): Add documentation.
5045 * src/scan-code.l: Implement the new interface.
5046 (code_lex): Make it static, add a code_props* argument, and remove the
5047 rule argument.
5048 (last_string): New static global similar to the one in scan-gram.l.
5049 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
5050 instead of rule.
5051 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
5052 code_props since Bison may one day use this information for destructors
5053 and printers.
5054 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
5055 (handle_action_dollar): Use symbol_list_n_get and set used flag
5056 directly since symbol_list_n_used_set is removed.
5057 (translate_action): Add a code_props* argument and remove the rule,
5058 action, and location arguments. Pass the code_props* on to code_lex.
5059 (translate_rule_action, translate_symbol_action, translate_code):
5060 Rewrite as wrappers around the new code_props interface.
5061 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
5062 it would eventually need to break the encapsulation of code_props.
5063
50642007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5065
5066 * etc/.cvsignore: New.
5067
50682007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5069
5070 Add maintainer-push-check to run maintainer-check using push parsing in
5071 place of pull parsing where available.
5072 * Makefile.am (maintainer-push-check): New.
5073 * data/bison.m4 (b4_use_push_for_pull_if): New.
5074 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
5075 appropriately based on their existing values.
5076 (yypush_parse): Don't print push-parser-specific diagnostics if push
5077 parsing is being used in place of pull parsing.
5078 * data/yacc.c: If push parsing should replace pull parsing, redirect to
5079 push.c.
5080 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
5081 variable, and insert b4_use_push_for_pull_flag into muscles.
5082 * tests/Makefile.am (maintainer-push-check): New.
5083
50842006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5085
5086 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
5087 (whether successful or failed) so that yypush_parse can be invoked
5088 again to start a new parse using the same yypstate.
5089 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
5090 check multiple yypull_parse invocations on the same yypstate. For pull
5091 mode, extend to check multiple yyparse invocations.
5092 (Exploding the Stack Size with Alloca): Extend to try with
5093 %push-pull-parser.
5094 (Exploding the Stack Size with Malloc): Likewise.
5095
5096 * tests/calc.at (Simple LALR Calculator): Don't specify
5097 %skeleton "push.c" since %push-pull-parser implies that now.
5098 * tests/headers.at (export YYLTYPE): Don't check for the push
5099 declarations. Otherwise, this test case can't be used to see if push
5100 mode can truly emulate pull mode.
5101 * tests/input.at (Torturing the Scanner): Likewise.
5102 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
5103 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
5104 AT_YACC_IF, which now includes the case of push mode since %skeleton
5105 need not be used for push mode. This will be more intuitive once
5106 push.c is renamed to yacc.c.
5107
51082006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5109
5110 For push mode, convert yyparse from a macro to a function, invoke yylex
5111 instead of passing a yylexp argument to yypull_parse, and don't
5112 generate yypull_parse or yyparse unless %push-pull-parser is declared.
5113 Discussed starting at
5114 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
5115 * data/bison.m4 (b4_pull_if): New.
5116 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
5117 * data/push.c: Improve M4 quoting a little.
5118 (b4_generate_macro_args, b4_parenthesize): Remove.
5119 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
5120 any time a pull parser is requested.
5121 Don't #define this as a wrapper around yypull_parse. Instead, when
5122 both push and pull are requested, make it a function that does that
5123 same thing.
5124 (yypull_parse): If there's a b4_prefix, #define this to
5125 b4_prefix[pull_parse] when both push and pull are requested.
5126 Don't define this as a function unless both push and pull are
5127 requested.
5128 Remove the yylexp argument and hard-code yylex invocation instead.
5129 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
5130 %push-parser.
5131 * src/getargs.c (pull_parser): New global initialized to true.
5132 * getargs.h (pull_parser): extern it.
5133 * src/output.c (prepare): Insert pull_flag muscle.
5134 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
5135 (prologue_declaration): Set both push_parser and pull_parser = true for
5136 %push-pull-parser. Set push_parser = true and pull_parser = false for
5137 %push-parser.
5138 * src/scan-gram.l: Don't accept %push_parser as an alternative to
5139 %push-parser since there's no backward-compatibility concern here.
5140 Scan %push-pull-parser.
5141 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
5142 instead of %push-parser.
5143 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
5144 prototype it in the module that calls yyparse.
5145 * tests/input.at (Torturing the Scanner): Likewise.
5146 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
5147
51482006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
5149
5150 Update etc/bench.pl. Optimize push mode a little (the yyn change
5151 deserves most of the credit).
5152 * Makefile.am (SUBDIRS): Add etc subdirectory.
5153 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
5154 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
5155 yytoken, yyval, and yyloc declarations to...
5156 (yyparse or yypush_parse): ... here to improve performance. For
5157 yypush_parse invocations after the first, be sure to assign yyn its old
5158 value again.
5159 (yypstate_new): Don't bother initializing the yyresult field since the
5160 initial value isn't used.
5161 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
5162 remove the #define that, in push mode, set it to yyps->NAME.
5163 * etc/Makefile.am: New.
5164 * etc/bench.pl: Remove and build it instead from...
5165 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
5166 "tests/bison" from the build directory by default rather than just
5167 invoking "bison" from $PATH.
5168 (calc_grammar): Update push parser code: don't declare yylval globally,
5169 don't define yyparse_wrapper, and don't #define yyparse.
5170 (bench_grammar): Update to check all working combinations of yacc.c,
5171 push.c, impure, pure, pull, and push.
5172
51732006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5174
5175 For push mode, add pull wrappers around yypush_parse.
5176 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
5177 (yypull_parse): New function wrapping yypush_parse.
5178 (yyparse): New #define wrapping yypull_parse.
5179 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
5180 is declared.
5181 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
5182 prototype yylex in the module that calls yyparse, and don't prototype
5183 yyparse there. Otherwise, the yyparse expansion won't compile.
5184 * tests/input.at (Torturing the Scanner): Likewise.
5185
51862006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5187
5188 Enable push parsers to operate in impure mode. Thus, %push-parser no
5189 longer implies %pure-parser. The point of this change is to move
5190 towards being able to test the push parser code by running the entire
5191 test suite as if %push-parser had been declared.
5192 * data/push.c (yypush_parse): For impure mode, remove the
5193 yypushed_char, yypushed_val, and yypushed_loc arguments.
5194 Instead, declare these as local variables initialized to the global
5195 yychar, yylval, and yylloc.
5196 For the first yypush_parse invocation only, restore the initial values
5197 of these global variables when it's time to read a token since they
5198 have been overwritten.
5199 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
5200 %push-parser.
5201 * tests/calc.at (Simple LALR(1) Calculator): Always declare
5202 %pure-parser along with %push-parser since this test case was designed
5203 for pure push parsers.
5204 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
5205 (AT_YACC_OR_PUSH_IF): New.
5206 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
5207 add a note that it's still wrong for some cases (as it has been for a
5208 while).
5209 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
5210 %push-parser no longer implies %pure-parser.
5211
52122006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5213
5214 Remove some unnecessary differences between the pull parser code and
5215 the push parser code. This patch enables yynerrs in push mode.
5216 * data/push.c: Reformat M4 a little.
5217 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
5218 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
5219 because push mode is on. Instead, if pure mode is on, move yynerrs
5220 to...
5221 (b4_declare_parser_state_variables): ... here.
5222 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
5223 to yyps->NAME so it can be used in yypush_parse.
5224 (yypush_parse): Don't omit uses of yynerrs in push mode.
5225
52262006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5227
5228 Fix bug such that the first pushed token's value and location are
5229 sometimes overwritten (sometimes by %initial-action) before being used.
5230 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
5231 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
5232 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
5233 more closely mimic the pull parser logic.
5234 Don't copy the pushed token to yychar, yylval, and yylloc until it's
5235 time to read a token, which is after any initialization of yylval and
5236 yylloc.
5237 (gottoken): Rename label to...
5238 (yyread_pushed_token): ... for clarity and to avoid infringing on the
5239 user namespace.
5240
52412006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5242
5243 Rearrange initialization of the parser state variables so that the
5244 skeleton doesn't have to have a copy for pull mode and another for push
5245 mode. This patch also fixes at least a bug such that yylloc was not
5246 initialized (with b4_location_initial_line and
5247 b4_location_initial_column) upon calling yypush_parse. However, that
5248 initialization now overwrites the first token's location;
5249 %initial-action assigning @$ already did the same thing, and both bugs
5250 will be fixed in a later patch.
5251 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
5252 (b4_declare_parser_state_variables): Remove initialization of yytoken,
5253 yyss, yyvs, yyls, and yystacksize.
5254 (yypstate_new): Remove initialization of some yypstate fields: yystate,
5255 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
5256 yylsp.
5257 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
5258 yyps->NAME so it can be used in yypush_parse.
5259 (yyparse or yypush_parse): For yypush_parse, don't print the
5260 "Starting parse" diagnostic for invocations after the first.
5261 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
5262 yypush_parse, only do it for the first invocation.
5263 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
5264 initialization to occur in yypush_parse but only on the first
5265 invocation.
5266
52672006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5268
5269 * data/push.c: Add CPP guards around push parser declarations in both
5270 the header and the code file.
5271 In the code file, move the push parser declarations to the same place
5272 they appear in the header file.
5273 Clean up the M4 some, especially the inconsistent underquoting in
5274 some b4_c_function_def and b4_c_function_decl uses.
5275
52762006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5277
5278 Encapsulate the push parser state variables into an M4 macro so the
5279 push skeleton doesn't have to list them again for pull mode's yyparse.
5280 For push mode, remove yypush_parse's local equivalents of these
5281 variables to eliminate unnecessary copying between the two sets at
5282 run-time. This patch also fixes at least a bug related to multiple
5283 %initial-action invocations in push mode.
5284 * data/push.c (b4_declare_parser_variables): Rename to...
5285 (b4_declare_scanner_communication_variables): ... this for clarity and
5286 update both uses.
5287 (b4_declare_yyparse_variables): Remove and move its contents to the one
5288 spot where it was invoked.
5289 (b4_declare_parser_state_variables): New macro containing the parser
5290 state variables required by push mode.
5291 (struct yypstate): Replace all fields but yynew with
5292 b4_declare_parser_state_variables.
5293 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
5294 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
5295 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
5296 (yyparse or yypush_parse): For yyparse in pull mode, replace local
5297 parser state variable declarations with
5298 b4_declare_parser_state_variables.
5299 Don't initialize parser state variables when calling yypush_parse since
5300 yypstate_new already does that.
5301 Invoke the user's initial action only upon the first yypush_parse
5302 invocation.
5303 Remove all code that copies between the local parser state variables
5304 and the yypstate.
5305
53062006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5307
5308 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
5309 prevent a name collision in a future patch where these names will
5310 sometimes be #define'd.
5311 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
5312 since it no longer has the same name as the existing argument.
5313 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
5314
53152006-12-19 Paolo Bonzini <bonzini@gnu.org>
5316 and Joel E. Denny <jdenny@ces.clemson.edu>
5317
5318 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
5319 that the argument is case-insensitive, and there's no `=' here.
5320 For the %skeleton entry, mention that %language is better.
5321 (Bison Options): Likewise for --language and --skeleton. Move the
5322 --skeleton entry so that the `Tuning the parser' section is sorted
5323 alphabetically on long options.
5324 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
5325 %language directive in detail here; cross-reference the %language
5326 documentation instead.
5327 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
5328 `%require "2.3b"' so that the example is always up-to-date.
5329 (Table of Symbols): Add entries for %language and %skeleton.
5330 * examples/extexi (normalize): Instead of replacing every %require
5331 argument with the current Bison version, just substitute for
5332 `@value{VERSION}'. This guarantees that we're testing what actually
5333 appears in the documentation.
5334 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
5335 rather than `@VERSION@'.
5336
53372006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5338
5339 * NEWS: Reword the %language news a bit, and put it earlier.
5340
5341 * src/getargs.c (skeleton_arg): Last arg is now location const *.
5342 Rewrite to simplify the logic.
5343 (language_argmatch): Likewise.
5344 (program_name): We now own this var.
5345 * src/getargs.h (struct bison_language): Use char[] rather than
5346 const char *.
5347
5348 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
5349 Java is supported.
5350 * src/complain.c (program_name): Remove decl; no longer needed.
5351 * src/main.c (program_name): Remove; now belongs to getargs.
5352
53532006-12-18 Paolo Bonzini <bonzini@gnu.org>
5354
5355 * NEWS: Document %language.
5356
5357 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
5358
5359 * data/c-skel.m4, data/c++-skel.m4: New files.
5360 * data/glr.c: Complain on push parsers.
5361
5362 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
5363 over %skeleton.
5364 (Decl Summary): Document %language and %skeleton.
5365 (Command line): Document -L.
5366
5367 * examples/extexi: Rewrite %require directive.
5368 * examples/calc++/Makefile.am: Pass VERSION to extexi.
5369
5370 * src/files.c (compute_exts_from_gc): Look in language structure
5371 for .y extension.
5372 (compute_file_name_parts): Check whether .tab should be added.
5373 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
5374 (language, skeleton_arg, language_argmatch): New.
5375 (long_options): Add --language.
5376 (getargs): Use skeleton_arg, add -L/--language.
5377 * src/getargs.h: Include location.h.
5378 (struct bison_language, language, skeleton_arg, language_argmatch): New.
5379 * src/output.c (prepare): Pick default skeleton from struct language.
5380 Don't dispatch C skeletons here.
5381 * src/parse-gram.y (PERCENT_LANGUAGE): New.
5382 (prologue_declaration): Add "%language" rule, use skeleton_arg.
5383 * src/scan-gram.l ("%language"): New rule.
5384
5385 * tests/calc.at: Test %skeleton and %language.
5386 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
5387 (AT_GLR_IF): Look for %skeleton "glr.cc".
5388 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
5389 (AT_YACC_IF): Reject %language.
5390
53912006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5392
5393 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5394 since it wasn't used; only the typedef name 'semantic_type' is needed.
5395 Also, omit trailing white space.
5396
5397 * bootstrap: Sync from coreutils.
5398 (gnulib_extra_files): Add build-aux/announce.gen.
5399 (slurp): Adjust .gitignore files like .cvsignore files.
5400 * build-aux/announce-gen: Remove from CVS, since bootstrap
5401 now creates this.
5402
54032006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5404
5405 Make %push-parser imply %pure-parser. This fixes several bugs; see
5406 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5407 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5408 pure_parser = true.
5409 * data/push.c: Don't bother testing b4_push_if when deciding whether
5410 to expand b4_declare_parser_variables globally.
5411 (yypush_parse): Likewise in here.
5412
5413 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5414 (yy_reduce_print): Reformat M4 for readability.
5415
54162006-12-15 Bob Rossi <bob@brasko.net>
5417 and Joel Denny <jdenny@ces.clemson.edu>
5418
5419 * data/push.c (yypstate): Add typedef, and update all uses of
5420 struct yypstate to just yypstate.
5421 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5422
54232006-12-14 Bob Rossi <bob@brasko.net>
5424
5425 * data/push.c (yypush_parse): Declare prototype regardless of
5426 %locations option.
5427
54282006-12-14 Bob Rossi <bob@brasko.net>
5429
5430 * data/push.c (yyparse): Remove the prototype and the #define when in
5431 push-parser mode.
5432
54332006-12-13 Bob Rossi <bob@brasko.net>
5434
5435 * data/push.c (yypstate_init): Rename to...
5436 (yypstate_new): ... this and use b4_c_function_def.
5437 (yypstate_delete): New.
5438 (yypush_parse): Change parameters yynval and yynlloc to be const.
5439 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5440 yypstate_delete functions.
5441
54422006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5443
5444 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5445 strange test case titles. Reported by Bob Rossi.
5446
54472006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5448
5449 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5450 of potential ambiguities in GLR grammers.
5451
54522006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5453
5454 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5455 `bison ', use m4_index instead of m4_substr since chopping up a string
5456 containing M4-special characters causes problems here.
5457
5458 Fix a couple of bugs related to special characters in user-specified
5459 file names, and make it easier for skeletons to compute output file
5460 names with the same file name prefix as Bison-computed output file
5461 names.
5462 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5463 b4_parser_file_name and b4_spec_defines_file instead of
5464 @output_parser_name@ and @output_header_name@, which are now redundant.
5465 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5466 b4_parser_file_name, b4_spec_defines_file, and the new
5467 @basename(FILENAME@) instead of @output_parser_name@ and
5468 @output_header_name@, which inappropriately escaped the file names as
5469 C string literals.
5470 * src/files.c (all_but_ext): Remove static qualifier.
5471 (compute_output_file_names): Move `free (all_but_ext)' to...
5472 (output_file_names_free): ... here since all_but_ext is needed later.
5473 * src/files.h (all_but_ext): Extern.
5474 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5475 exactly what MUSCLE_INSERT_STRING used to do.
5476 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5477 characters are escaped properly.
5478 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5479 all_but_ext.
5480 For pkgdatadir muscle, maintain previous functionality by using
5481 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5482 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5483 digraphs would never be expanded. Hopefully no one has M4-special
5484 characters in his Bison installation path.
5485 * src/scan-skel.l: Don't parse @output_header_name@ and
5486 @output_parser_name@ anymore since they're now redundant.
5487 In @output, use decode_at_digraphs.
5488 Parse a new @basename command that invokes last_component.
5489 (decode_at_digraphs): New.
5490 (BASE_QPUTS): Remove unused.
5491 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
5492 (Output file name): New tests.
5493
54942006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
5495
5496 Warn about output files that are generated by the skeletons and that
5497 conflict with other output files.
5498 * data/glr.c: Don't generate the header file here when glr.cc does.
5499 * src/files.c (file_names, file_names_count): New static globals.
5500 (compute_output_file_names): Invoke output_file_name_check for files
5501 not generated by the skeletons and remove existing checks.
5502 (output_file_name_check): New function that warns about conflicting
5503 output file names.
5504 (output_file_names_free): Free file_names.
5505 * src/files.h (output_file_name_check): Declare.
5506 * src/scan-skel.l: Invoke output_file_name_check for files generated by
5507 the skeletons.
5508 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
5509 (Conflicting output files): New tests.
5510
55112006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5512
5513 * doc/bison.texinfo: Fix a couple of typos.
5514
55152006-12-08 Bob Rossi <bob@brasko.net>
5516
5517 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
5518 Rename to...
5519 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
5520 update all uses.
5521 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
5522 (yypush_parse): Rename yypvars argument to yyps and remove redundant
5523 local pv.
5524 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
5525 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
5526
55272006-12-07 Bob Rossi <bob@brasko.net>
5528 and Joel Denny <jdenny@ces.clemson.edu>
5529
5530 * data/push.c (yypvarsinit): Change return type from void* to struct
5531 yypvars*. No longer cast to void* on return.
5532 (struct yypvars): Remove yylen since it need not be remembered between
5533 yypushparse invocations.
5534 (yypushparse): Don't copy between yylen and pv->yylen.
5535
55362006-12-05 Bob Rossi <bob@brasko.net>
5537
5538 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
5539 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
5540 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
5541 (struct yypvars): Remove b4_declare_parser_variables.
5542 (yypvarsinit): Remove init code for removed variables.
5543 (global scope): Do not declare b4_declare_parser_variables if
5544 push or pure mode.
5545 (yypushparse): Add b4_declare_parser_variables.
5546 Init new local variables, and remove init code for removed
5547 yypvars variables.
5548 (yyparse): Delete.
5549 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
5550 and yyparse for other modes.
5551 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
5552 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
5553 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
5554 (AT_PURE_LEX_IF): True if pure or push parser.
5555

5633 * src/getargs.c: Fix some typos in Doxygen comments.
5634
56352006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
5636
5637 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
5638 later. Reported by Paul Eggert in
5639 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
5640 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
5641 * src/scan-code.l (translate_action): Don't bother invoking
5642 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
5643 (code_scanner_free): Instead of invoking
5644 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
5645 which frees more.
5646 * src/scan-gram.l (gram_scanner_free): Likewise.
5647 * src/scan-skel.l (scan_skel): Likewise.
5648
56492006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
5650
5651 * src/files.c (tr): Change return type to void.
5652 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
5653 has been called previously for the same key.
5654 (muscle_find): Return storage instead of value so that
5655 --enable-gcc-warnings doesn't produce warnings that the return discards
5656 const. aver that the value and storage are the same since storage
5657 could potentially be NULL when value is not.
5658 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
5659 same as 0.
5660
56612006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5662
5663 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
5664 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
5665 us a slightly cleaner distribution, and also works.
5666 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
5667 gnulib changes.
5668
56692006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
5670 and Paul Eggert <eggert@cs.ucla.edu>
5671
5672 Don't let Bison leak memory except when it complains.
5673 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
5674 (spec_defines_file, dir_prefix): Now char *, not const char *,
5675 since they are freed.
5676 * src/files.c: Likewise.
5677 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
5678 Likewise.
5679 (tr): Now operates in-place. All uses changed.
5680 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
5681 values.
5682 (compute_file_name_parts, compute_output_file_names): Don't store
5683 read-only data in variables that will be freed.
5684 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
5685 src_extension, and header_extension.
5686 (output_file_names_free): New public function to free
5687 spec_verbose_file, spec_graph_file, spec_defines_file,
5688 parser_file_name, and dir_prefix.
5689 * src/getargs.c (getargs): Don't store read-only data in variables that
5690 will be freed.
5691 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
5692 (which previously existed but was unused), and quotearg_free.
5693 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
5694 * src/muscle_tab.c: Likewise.
5695 (muscle_entry): Make the value char const *,
5696 and add a new storage member that is char * and can be freed.
5697 (muscle_entry_free): New private function.
5698 (muscle_init): Use it instead of free.
5699 (muscle_insert, muscle_grow): Update and use new storage member.
5700 (muscle_code_grow): Free the string passed to muscle_grow
5701 since it's not needed anymore.
5702 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
5703 add a new `char *code' member.
5704 ("{...}"): Declare semantic type as code.
5705 * src/scan-code.h (translate_rule_action):
5706 (translate_symbol_action, translate_code, translate_action): Return
5707 `char const *' rather than `char *' since external code should not free
5708 these strings.
5709 * src/scan-code.l: Likewise.
5710 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
5711 which is "{...}" in the parser.
5712 * tests/Makefile.am (maintainer-check-valgrind): Set
5713 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
5714 Valgrind.
5715 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
5716 complain.
5717 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
5718 expecting a non-zero exit status sets --leak-check=summary and
5719 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
5720 this case, and we don't want to hear about it.
5721
57222006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5723
5724 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
5725 instead of from the template, to simplify configuration a bit.
5726 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
5727 and m4/wint_t.m4, as they are needed with the latest gnulib.
5728
57292006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
5730
5731 Disable unset/unused mid-rule value warnings by default, and recognize
5732 --warnings=midrule-values to enable them. Discussed starting at
5733 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
5734 * NEWS (2.3a+): Mention.
5735 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum
5736 warnings): Add entry for midrule-values subargument.
5737 * src/reader.c (symbol_should_be_used): Don't return true just because
5738 the value is a set/used mid-rule value unless
5739 --warnings=midrule-values was specified.
5740 * tests/input.at (Unused values, Unused values before symbol
5741 declarations): Run tests with and without --warnings=midrule-values.
5742
5743 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
5744 than LIST_FREE directly.
5745
57462006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
5747
5748 Finish implementing --warnings=error, which should not be implied by
5749 --warnings=all (or by its synonyms -W and --warnings without
5750 subarguments).
5751 * src/complain.c (set_warning_issued): New function to report that
5752 warnings are being treated as errors and to record an error if so.
5753 Invoke...
5754 (warn_at, warn): ... here.
5755 * src/getargs.c (warnings_args, warnings_types): Reorder so that
5756 "error - warnings are errors" does not appear above "all - all of the
5757 above".
5758 (getargs): For -W and --warnings without subarguments, don't let
5759 FLAGS_ARGMATCH set warnings_error in warnings_flag.
5760 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
5761
57622006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
5763
5764 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
5765 empty subargument list. For example: `bison --warnings= parser.y'.
5766
57672006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5768
5769 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
5770 the parser header file so that gcc doesn't warn.
5771
57722006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5773
5774 Split the default %destructor/%printer into two kinds: <*> and <!>.
5775 Discussed starting at
5776 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
5777 * NEWS (2.3a+): Mention.
5778 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
5779 previous change today related to mid-rules.
5780 (Table of Symbols): Remove %symbol-default and add <*> and <!>.
5781 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
5782 (TYPE_TAG_ANY): Add as <*>.
5783 (TYPE_TAG_NONE): Add as <!>.
5784 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
5785 for <*> and <!>.
5786 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
5787 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
5788 * src/symlist.c (symbol_list_default_new): Split into tagged and
5789 tagless versions.
5790 (symbol_list_destructor_set, symbol_list_printer_set): Split
5791 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
5792 SYMLIST_DEFAULT_TAGLESS.
5793 * src/symlist.h: Update symbol_list_default*_new prototypes.
5794 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
5795 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
5796 * src/symtab.c (default_destructor, default_destructor_location,
5797 default_printer, default_printer_location): Split each into tagged and
5798 tagless versions.
5799 (symbol_destructor_get, symbol_destructor_location_get,
5800 symbol_printer_get, symbol_printer_location_get): Implement tagged
5801 default and tagless default cases.
5802 (default_destructor_set, default_printer_set): Split each into tagged
5803 and tagless versions.
5804 * src/symtab.h: Update prototypes.
5805 * tests/actions.at (Default %printer and %destructor): Rename to...
5806 (Default tagless %printer and %destructor): ... this, and extend.
5807 (Per-type %printer and %destructor): Rename to...
5808 (Default tagged and per-type %printer and %destructor): ... this, and
5809 extend.
5810 (Default %printer and %destructor for user-defined end token): Extend.
5811 (Default %printer and %destructor are not for error or $undefined):
5812 Update.
5813 (Default %printer and %destructor are not for $accept): Update.
5814 (Default %printer and %destructor for mid-rule values): Extend.
5815 * tests/input.at (Default %printer and %destructor redeclared): Extend.
5816 (Unused values with default %destructor): Extend.
5817
58182006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5819
5820 Don't apply the default %destructor/%printer to an unreferenced midrule
5821 value. Mentioned at
5822 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
5823 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
5824 like $@n instead of just @n so that the default %destructor/%printer
5825 logic doesn't see them as user-defined symbols.
5826 (symbol_is_dummy): Check for both forms of the name.
5827 * src/reader.c (packgram): Remove the `$' from each midrule symbol
5828 name for which the midrule value is referenced in any action.
5829 * tests/actions.at (Default %printer and %destructor for mid-rule
5830 values): New test.
5831 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
5832 for change to dummy symbol names.
5833
58342006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
5835
5836 Warn about unset midrule $$ if the corresponding $n is used.
5837 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
5838 $n usage.
5839 (packgram): Before invoking grammar_rule_check on any rule, make sure
5840 all actions have already been scanned in order to set `used' flags.
5841 Otherwise, checking that a midrule's $$ is set will not always work
5842 properly because the midrule check must forward-reference the midrule's
5843 parent rule.
5844 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
5845 warning.
5846
58472006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
5848
5849 More improvements to the documentation of the prologue alternatives:
5850 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
5851 Bison manual.
5852 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
5853 some text to clarify the relative importance of the new directives and
5854 to show how these directives may be viewed as code labels.
5855
58562006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
5857
5858 Similar to the recently removed %before-header, add %code-top as the
5859 alternative to the pre-prologue. Mentioned at
5860 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
5861 Also, let the prologue alternatives appear in the grammar section.
5862 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
5863 (prologue_declaration): Move the existing prologue alternatives to...
5864 (grammar_declaration): ... here and add %code-top.
5865 * src/scan-gram.l (PERCENT_CODE_TOP): New token.
5866
5867 Clean up and extend documentation for the prologue alternatives.
5868 * NEWS (2.3a+): Describe prologue alternatives.
5869 * doc/bison.texinfo (Prologue): Move discussion of prologue
5870 alternatives to...
5871 (Prologue Alternatives): ... this new section, and extend it to discuss
5872 all 4 directives in detail.
5873 (Table of Symbols): Clean up discussion of prologue alternatives and
5874 add %code-top.
5875
58762006-10-16 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5877
5878 DJGPP specific issues.
5879

5881 config.bat accordingly.
5882 * djgpp/config.sed: Adjust config.sed for the use of autoconf 2.60.
5883 * djgpp/config.site: Likewise.
5884
58852006-10-16 Paolo Bonzini <bonzini@gnu.org>

5888 http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00002.html
5889
5890 * data/bison.m4 (b4_user_requires, b4_user_provides): New.
5891 (b4_user_start_header): Remove.
5892 * data/glr.c: Use new macros instead of b4_*start_header
5893 and b4_*end_header.
5894 * data/glr.cc: Likewise.
5895 * data/lalr1.cc: Likewise.
5896 * data/push.c: Likewise.

5909 Problem reported by Joel E. Denny.
5910
59112006-10-14 Jim Meyering <jim@meyering.net>
5912
5913 (Sync from coreutils.)
5914 Work also when the working directory (with e.g. coreutils sources)
5915 is version controlled with git, rather than CVS.
5916 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
5917 rather than CVS.
5918 In messages and comments, say e.g., "checked-out sources",
5919 rather than "CVS sources".
5920 (version_controlled_file): New function. Work for git as well as
5921 for CVS. Don't use grep's -q option.
5922 (slurp): Call it here, in place of CVS-specific code.
5923
59242006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
5925
5926 Fix testsuite for ./configure --enable-gcc-warnings:
5927 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
5928 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
5929 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
5930 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
5931 * test/regression.at (Diagnostic that expects two alternatives):
5932 Likewise.
5933
59342006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5935
5936 * bootstrap.conf (gnulib_modules): Add config-h.
5937 * djgpp/subpipe.c: Include <config.h> unconditionally; don't
5938 worry about HAVE_CONFIG_H.
5939 * lib/abitset.c: Likewise.
5940 * lib/bitset.c: Likewise.
5941 * lib/bitset_stats.c: Likewise.
5942 * lib/bitsetv-print.c: Likewise.
5943 * lib/bitsetv.c: Likewise.

5947 * lib/subpipe.c: Likewise.
5948 * lib/timevar.c: Likewise.
5949 * lib/vbitset.c: Likewise.
5950 * lib/bitset.c: Include "bitset.h" first, to test interface.
5951 * lib/bitset_stats.c: Include "bitset_stats.h" first.
5952 * lib/bitsetv-print.c: Include "bitsetv-print.h" first.
5953 * lib/bitsetv.c: Include "bitsetv.h" first.
5954 * lib/get-errno.c: Include "get-errno.h" first.
5955 * m4/.cvsignore: Add config-h.m4.
5956 * tests/actions.at (Default %printer and %destructor for ...):
5957 Adjust expected line numbers in output to reflect removal of #if
5958 HAVE_CONFIG_H lines.
5959 * tests/glr-regression.at (Missed %merge type warnings when ...):
5960 Likewise.
5961 * tests/regression.at (Braced code in declaration in rules section):
5962 Likewise.
5963 * tests/atlocal.in (CPPFLAGS): Don't define HAVE_CONFIG_H.
5964 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
5965 Include <config.h> unconditionally.
5966
5967 * bootstrap: Sync from coreutils, as follows:
5968
5969 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
5970
5971 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
5972 variable was sometimes used without being initialized. This
5973 messed up the installation of the INSTALL file in some cases.
5974
5975 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5976
5977 * bootstrap (usage, main program, symlink_to_gnulib): Add option
5978 --copy. Inspired by a suggestion from Bruno Haible.
5979
5980 2006-10-03 Jim Meyering <jim@meyering.net>
5981
5982 * bootstrap: Undo last change to this file, since now gnulib-tool
5983 sticks with the automake default in generating dependencies.
5984
59852006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5986
5987 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
5988 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
5989
5990 * doc/bison.1: Add copyright notice.
5991
5992 * data/glr.c: Don't include <stdarg.h>; not used.
5993
5994 * NEWS: The -g and --graph options now output graphs in Graphviz
5995 DOT format, not VCG format.
5996 * doc/bison.1: Likewise.
5997 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
5998 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
5999 of this change in
6000 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
6001 * TODO: Remove Graphviz entry.
6002 * src/Makefile.am (bison_SOURCES): Add graphviz.c and graphviz.h;
6003 remove vcg.c, vcg.h, vcg_defaults.h.
6004 * src/vcg.c, src/vcg.h, src/vcg_defaults.h: Remove.
6005 * src/graphviz.c, src/graphviz.h: New files.

6009 * src/print_graph.h: Likewise.
6010 * src/getargs.c (usage): Make usage description more generic.
6011 * src/print_graph.c: Include graphviz.h rather than vcg.h.
6012 (static_graph, fgraph): Remove. All uses changed to pass
6013 arguments instead of sharing a static var.
6014 (print_core, print_actions, print_state, print_graph):
6015 Output graphviz format rather than VCG format.
6016 * tests/.cvsignore: Remove *.vcg; add *.dot.
6017 * tests/output.at: Expect *.dot files, not *.vcg files.
6018
6019 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
6020 accommodates the 2006-10-08 change.
6021
60222006-10-11 Bob Rossi <bob@brasko.net>
6023
6024 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.
6025 (b4_yyssa, b4_yyerror_range): New macros.
6026 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
6027 (yypvarsinit): Remove init of removed fields.
6028 (yypushparse): Remove use of removed fields; use new macros instead.
6029
60302006-10-11 Paul Eggert <eggert@cs.ucla.edu>
6031
6032 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
6033 in a push parser. Reindent slightly to match yacc.c better.
6034
60352006-10-11 Bob Rossi <bob@brasko.net>
6036
6037 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
6038 yymsg_alloc fields.
6039 (yypvarsinit, yypushparse): Remove init of removed fields.

6043
6044 * THANKS: Add Paolo Bonzini and Bob Rossi.
6045
60462006-10-08 Paolo Bonzini <bonzini@gnu.org>
6047
6048 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
6049 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
6050 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
6051 b4_define_user_cde and uses): Remove.
6052 (b4_comment, b4_prefix, b4_sync_start): New.
6053 * data/bison.m4: New file, with most of the content removed from c.m4.
6054 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
6055 * src/output.c (output_skeleton): Pass bison.m4.
6056 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
6057 only if specified.
6058
60592006-10-05 Paul Eggert <eggert@cs.ucla.edu>
6060
6061 Fix test failure reported by Tom Lane in
6062 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
6063 and try to make such failures easier to catch in the future.
6064 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
6065 that's now the caller's responsibility.
6066 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
6067 Set yychar = YYEOF if it's negative.
6068 * tests/actions.at (yylex): Abort if asked to read past EOF.
6069 * tests/conflicts.at (yylex): Likewise.
6070 * tests/cxx-type.at (yylex): Likewise.
6071 * tests/glr-regression.at (yylex): Likewise.
6072 * tests/input.at (yylex): Likewise.
6073 * tests/regression.at (yylex): Likewise.
6074 * tests/torture.at (yylex): Likewise.
6075
60762006-10-01 Paul Eggert <eggert@cs.ucla.edu>
6077
6078 Fix problems with translating English-language diagnostics.
6079 * bootstrap: Fix bug introduced in recent bootstrap changes, with
6080 respect to bison-runtime pot generation. The YY_ stuff
6081 wasn't being captured.
6082 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
6083 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
6084 * runtime-po/POTFILES.in: Add data/push.c.
6085
60862006-09-29 Paul Eggert <eggert@cs.ucla.edu>
6087
6088 Merge bootstrap changes from coreutils.
6089
6090 2006-09-28 Jim Meyering <jim@meyering.net>
6091
6092 Automatically generated dependencies are important even
6093 when all of the sources in a directory come from gnulib.
6094 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
6095 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
6096
6097 2006-09-23 Jim Meyering <jim@meyering.net>
6098
6099 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
6100
6101 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6102
6103 * bootstrap: Add support for --force.
6104 (usage): New function. Describe usage less tersely.
6105 (CVS_only_file): New var.
6106
61072006-09-21 Paul Eggert <eggert@cs.ucla.edu>
6108
6109 * data/push.c (YYPUSH_MORE): Make it an enum instead.
6110 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
6111 Adjust white space and comments to match GNU style better.
6112
61132006-09-20 Bob Rossi <bob@brasko.net>
6114
6115 * data/push.c (yyresult_get): Remove function.
6116 (YYPUSH_MORE): Add #define.
6117 (yypushparse): Modify return value.
6118
61192006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6120
6121 * stamp-h.in: Remove; no longer needed.
6122 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
6123 Remove config.h, config.hin, intl (no longer created).
6124 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
6125 stamp-h1.
6126
6127 Sync bootstrap from coreutils, as follows:
6128
6129 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
6130
6131 * bootstrap (symlink_to_gnulib): New function.
6132 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
6133 to copies-of-gnulib.
6134 (cp_mark_as_generated, slurp, gnulib_files):
6135 Avoid making a copy if it's the same as the old version.
6136 (gnulib_files): Add support for this variable (used by Bison).
6137
61382006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6139
6140 * src/getargs.c (usage): Rework to use conventions similar to
6141 coreutils, to make translation a bit easier and the code a bit
6142 smaller. Problem reported by Tim Van Holder.
6143
61442006-09-15 Paul Eggert <eggert@cs.ucla.edu>
6145
6146 Use some of gnulib's new modules, taken from coreutils.
6147
6148 * bootstrap: Sync from coreutils, except add support for gnulib_files.
6149 * bootstrap.conf: New file.
6150 (gnulib_modules): Add configmake, inttypes, unistd.
6151 (XGETTEXT_OPTIONS): Add complain, complain_at,
6152 fatal, fatal_at, warn, warn_at, unexpected_end.
6153 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
6154 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
6155 (gl_EARLY): Add.
6156 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
6157 (gl_INIT): Add
6158 (GNULIB_AUTOCONF_SNIPPET): Remove.
6159 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
6160 the pickiest.
6161 * lib/.cvsignore: Add inttypes_.h.
6162 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
6163 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
6164 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
6165 no-longer-necessary initializations.
6166 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
6167 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
6168 use the unistd module.
6169 * src/system.h: Likewise.
6170 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
6171 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
6172 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
6173 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
6174 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
6175 * src/system.h: Include inttypes.h unconditionally, now that we
6176 use the inttypes module. Don't bother to include stdint.h, since
6177 inttypes.h now does that for us.
6178 (LOCALEDIR): Remove, now that we use the configmake module.
6179 * src/getargs.c: Include configmake.h.
6180 * src/main.c: Likewise.
6181 * src/output.c: Likewise.
6182 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
6183 not from $abs_top_builddir, since config.h moved.
6184
6185
6186 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
6187 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
6188
6189 * src/parse-gram.y (symbol_declaration): Don't put statements
6190 before declarations; it's not portable to C89.
6191 * src/scan-code.l (handle_action_at): Likewise.
6192
6193 * src/scan-code.l: Always initialize braces_level; the old code
6194 left it uninitialized and therefore had undefined behavior.
6195
6196 Don't attempt to redefine 'assert', since it runs afoul of
6197 systems where standard headers (mistakenly) include <assert.h>.
6198 Instead, define and use our own alternative, called 'aver'.
6199 * src/reader.c: Don't include assert.h, since we no longer
6200 use assert.
6201 * src/scan-code.l: Likewise.
6202 * src/system.h (assert): Remove, replacing with....
6203 (aver): New function, taking a bool arg. All uses changed.
6204 * src/tables.c (pack_vector): Ensure that aver arg is bool,
6205 not merely an integer.
6206
62072006-09-15 Bob Rossi <bob@brasko.net>
6208
6209 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
6210 * data/c.m4 (YYPUSH): New.
6211 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
6212 * src/getargs.c (push_parser): New var.
6213 * src/getargs.h (push_parser): New declaration.
6214 * src/output.c (prepare): Add macro insertion of `push_flag'.
6215 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
6216 (prologue_declaration): Parse %push-parser.
6217 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
6218 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
6219 list of removed lines from the traces observed.
6220 (AT_CHECK_CALC_LALR): Added push parser tests.
6221
62222006-09-13 Paul Eggert <eggert@cs.ucla.edu>
6223
6224 * NEWS: Version 2.3a.
6225 * configure.ac (AC_INIT): Likewise.
6226
6227 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
6228 "#define YYSTYPE int" that caused "make maintainer-check" to fail
6229 due to header ordering dependencies. I don't know why the #define
6230 was there.
6231
6232 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
6233 runtime cost when YYDEBUG is not defined, and so that some tests
6234 that used to fail now work. Problem and initial suggestion by
6235 Paolo Bonzini.
6236 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
6237 * data/glr.cc (b4_parser_class_name):
6238 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
6239 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
6240 (yydebug_) [YYDEBUG]: New member.
6241 (yycdebug_): Now defined only if YYDEBUG.
6242 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
6243 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
6244 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
6245 if YYYDEBUG.
6246 (debug_stream, set_debug_stream, debug_level, set_debug_level):
6247 Define only if YYDEBUG.
6248 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
6249 set_debug_level.
6250 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
6251 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
6252 AT_CHECK_CALC_GLR_CC that are working now.
6253
62542006-09-12 Paul Eggert <eggert@cs.ucla.edu>
6255
6256 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
6257 We don't need them in glr.cc, and glr.c defines them.
6258 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
6259 assumes that defining it to anything is the same as defining
6260 it to 1. Problem reported by Paolo Bonzini.
6261
62622006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
6263
6264 * data/c.m4 (b4_null, b4_case): Define.
6265 * src/output.c (prepare_symbols): Use b4_null.
6266 (user_actions_output): Use b4_case.
6267
62682006-09-11 Paul Eggert <eggert@cs.ucla.edu>
6269
6270 * data/glr.c (b4_shared_declarations): Put start-header first,
6271 before any #includes that we generate, so that feature-test
6272 macros work. Problem reported by Michael Deutschmann in
6273 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
6274 * data/lalr1.cc: Likewise.
6275 * doc/bison.texinfo (Prologue): Document that feature-test macros
6276 should be defined before any Bison declarations.
6277 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
6278 that depend on location.hh after, not before, Bison decls, since
6279 we now include location.hh after the first user prologue.
6280
6281 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
6282 Sander Brandenburg in
6283 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
6284 Also, fix minor white space and comment issues.
6285 (Prologue): Mention that it's better to define feature-test macros
6286 before Bison declarations. Problem reported by Michael Deutschmann.
6287
6288 * README-cvs: Fix typo: "&" should be "&&". Problem reported
6289 by Jim Meyering.
6290 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
6291 This adjusts to recent gnulib changes.
6292
62932006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6294
6295 Finish implementation of per-type %destructor/%printer. Discussed
6296 starting at
6297 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
6298 and
6299 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
6300 * NEWS (2.3+): Add a description of this feature to the default
6301 %destructor/%printer description.
6302 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
6303 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6304 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
6305 list node contains a semantic type.
6306 * src/symtab.c, src/symtab.h: Extend with a table that associates
6307 semantic types with their %destructor's and %printer's.
6308 (semantic_type_from_uniqstr, semantic_type_get,
6309 semantic_type_destructor_set, semantic_type_printer_set): New functions
6310 composing the public interface of that table.
6311 (symbol_destructor_get, symbol_destructor_location_get,
6312 symbol_printer_get, symbol_printer_location_get): If there's no
6313 per-symbol %destructor/%printer, look up the per-type before trying
6314 the default.
6315 * tests/actions.at (Per-type %printer and %destructor): New test case.
6316 * tests/input.at (Default %printer and %destructor redeclared):
6317 Extend to check that multiple occurrences of %symbol-default in a
6318 single %destructor/%printer declaration is an error.
6319 (Per-type %printer and %destructor redeclared, Unused values with
6320 per-type %destructor): New test cases.
6321
63222006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6323
6324 Require default %destructor/%printer to be declared using
6325 %symbol-default instead of an empty symbol list, and start working on
6326 new per-type %destructor/%printer. Discussed at
6327 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
6328 * NEWS (2.3+): Add %symbol-default to example.
6329 * bison.texinfo (Freeing Discarded Symbols): Likewise.
6330 (Table of Symbols): Add entry for %symbol-default.
6331 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
6332 (generic_symlist, generic_symlist_item): New nonterminals for creating
6333 a list in which each item is a symbol, semantic type, or
6334 %symbol-default.
6335 (grammar_declaration): Use generic_symlist in %destructor and %printer
6336 declarations instead of symbols.1 or an empty list.
6337 (symbol_declaration, precedence_declaration, symbols.1): Update actions
6338 for changes to symbol_list.
6339 * src/reader.c: Update for changes to symbol_list.
6340 * src/scan-code.l: Likewise.
6341 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
6342 * src/symlist.c, src/symlist.h: Extend such that a list node may
6343 represent a semantic type or a %symbol-default in addition to just an
6344 ordinary symbol. Add switched functions for setting %destructor's and
6345 %printer's.
6346 * tests/actions.at, tests/input.at: Add %symbol-default to all default
6347 %destructor/%printer declarations.
6348
63492006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
6350
6351 Whether the default %destructor/%printer applies to a particular symbol
6352 isn't a question of whether the user *declares* that symbol (in %token,
6353 for example). It's a question of whether the user by any means
6354 *defines* the symbol at all (by simply using a char token, for
6355 example). $end is defined by Bison whereas any other token with token
6356 number 0 is defined by the user. The error token is always defined by
6357 Bison regardless of whether the user declares it with %token, but we
6358 may one day let the user define error as a nonterminal instead.
6359 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6360 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
6361 the meaning of "user-defined".
6362 * tests/actions.at (Default %printer and %destructor for user-declared
6363 end token): Rename to...
6364 (Default %printer and %destructor for user-defined end token): ...
6365 this.
6366
6367 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
6368 computation of whether to apply the default, don't maintain a list of
6369 every Bison-defined symbol. Instead, just check for a first character
6370 of '$', which a user symbol cannot have, and check for the error token.
6371
63722006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
6373
6374 Don't apply the default %destructor or %printer to the error token,
6375 $undefined, or $accept. This change fits the general rule that the
6376 default %destructor and %printer are only for user-declared symbols,
6377 and it solves several difficulties that are described in the new test
6378 cases listed below.
6379 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
6380 * tests/actions.at (Default %printer and %destructor are not for error
6381 or $undefined, Default %printer and %destructor are not for $accept):
6382 New test cases.
6383
63842006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
6385
6386 Allow %start after the first rule.
6387 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
6388 when parsing the first rule.
6389 (check_and_convert_grammar): Search for it here after all grammar
6390 declarations have been parsed. Skip midrules, which have dummy LHS
6391 nonterminals.
6392 * src/symtab.c (symbol_is_dummy): New function.
6393 * src/symtab.h (symbol_is_dummy): Declare it.
6394 * tests/input.at (%start after first rule): New test.
6395
63962006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6397
6398 Redo some of the previous commit: add back the ability to use
6399 non-aliased/undeclared string literals since it might be useful to
6400 those declaring %token-table.
6401 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6402 commit: don't worry about complaints from symbols_pack.
6403 * src/symtab.c (symbol_new, symbol_class_set,
6404 symbol_check_alias_consistency): Undo changes in previous commit: count
6405 each string literal as a new symbol and token, assign it a symbol
6406 number, and don't complain about non-aliased string literals.
6407 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6408 and token counts but does still set aliased tokens to the same number,
6409 symbol_pack_processor now leaves empty slots in the symbols array.
6410 Remove those slots.
6411 * tests/regression.at (Undeclared string literal): Remove test case
6412 added in previous commit since non-aliased string literals are allowed
6413 again.
6414 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6415 remove unnecessary string literal declarations.
6416 * tests/sets.at (Firsts): Likewise.
6417
64182006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6419
6420 Don't allow an undeclared string literal, but allow a string literal to
6421 be used before its declaration.
6422 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6423 symbols_pack complained.
6424 * src/symtab.c (symbol_new): Don't count a string literal as a new
6425 symbol.
6426 (symbol_class_set): Don't count a string literal as a new token, and
6427 don't assign it a symbol number since symbol_make_alias does that.
6428 (symbol_make_alias): It's not necessary to decrement the symbol and
6429 token counts anymore. Don't assume that an alias declaration occurs
6430 before any uses of the identifier or string, and thus don't assert that
6431 one of them has the highest symbol number so far.
6432 (symbol_check_alias_consistency): Complain if there's a string literal
6433 that wasn't declared as an alias.
6434 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6435 symbol_pack asserts that every token has been assigned a symbol number
6436 although undeclared string literals have not.
6437 * tests/regression.at (String alias declared after use, Undeclared
6438 string literal): New test cases.
6439 (Characters Escapes, Web2c Actions): Declare string literals as
6440 aliases.
6441 * tests/sets.at (Firsts): Likewise.
6442
64432006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6444
6445 In the grammar scanner, STRING_FINISH unclosed constructs and return
6446 them to the parser in order to improve error messages.
6447 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6448 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6449 * tests/input.at (Unclosed constructs): New test case.
6450 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6451 seen.
6452
6453 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6454 unused global.
6455
64562006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6457
6458 Handle string aliases for character tokens correctly.
6459 * src/symtab.c (symbol_user_token_number_set): If the token has an
6460 alias, check and set its alias's user token number instead of its own,
6461 which is set to indicate the alias. Previously, every occurrence of
6462 the character token in the grammar overwrote that alias indicator with
6463 the character code.
6464 * tests/input.at (String aliases for character tokens): New test.
6465
64662006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6467
6468 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6469
64702006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6471
6472 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6473 to prevent failures when building on older platforms.
6474 Check for autopoint failure.
6475 Set XGETTEXT_OPTIONS to values that check for C format strings,
6476 so that translators are warned about them (this also helps
6477 prevent core dumps).
6478
6479 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6480 function, since it simplifies our code a bit.
6481
6482 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6483 rather than -W, so we don't get bogus warnings about sign comparisons.
6484 Add -Wpointer-arith, since that warning is useful (it reports code
6485 that does not conform to C89 and that some compilers reject).
6486 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6487 since it's no longer needed.
6488
64892006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6490
6491 Clean up scanners a bit.
6492 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6493 definitions so gcc won't warn when obstack_for_string is unused.
6494 * src/scan-code.l: config.h and system.h are already #include'd by
6495 scan-code-c.c, so get rid of them here.
6496 * src/scan-gram.l: Likewise.
6497 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6498 definitions rather than duplicating the rest of it.
6499 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6500
65012006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6502
6503 Suppress signed/unsigned comparison warnings for yycheck.
6504 * data/c.m4 (b4_safest_int_type): New macro.
6505 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6506 a signed int type, cast it to b4_safest_int_type first.
6507 * data/yacc.c: Likewise.
6508 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6509 also overwritten.
6510
65112006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6512
6513 * doc/bison.texinfo: Fix some typos.
6514
65152006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6516
6517 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6518 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6519
6520 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6521 the latest gnulib does this a different way.
6522 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6523 translation was patched, so stop omitting it.
6524
65252006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6526
6527 Enable declaration of default %printer/%destructor. Make the parser
6528 use these for all user-declared grammar symbols for which the user does
6529 not declare a specific %printer/%destructor. Thus, the parser uses it
6530 for token 0 if the user declares it but not if Bison generates it as
6531 $end. Discussed starting at
6532 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6533 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6534 and
6535 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6536 * NEWS (2.3+): Mention.
6537 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
6538 declare a %destructor for a mid-rule's semantic value. It's just
6539 impossible to declare one specific to it.
6540 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
6541 code. Describe default %destructor form.
6542 * src/parse-gram.y (grammar_declaration): Parse default
6543 %printer/%destructor declarations.
6544 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
6545 and symbol_destructor_location_get rather than accessing the destructor
6546 and destructor_location members of struct symbol.
6547 (symbol_printers_output): Likewise but for %printer's.
6548 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
6549 again.
6550 * src/symtab.c (default_destructor, default_destructor_location,
6551 default_printer, default_printer_location): New static global
6552 variables to record the default %destructor and %printer.
6553 (symbol_destructor_get, symbol_destructor_location_get,
6554 symbol_printer_get, symbol_printer_location_get): New functions to
6555 compute the appropriate %destructor and %printer for a symbol.
6556 (default_destructor_set, default_printer_set): New functions to set the
6557 default %destructor and %printer.
6558 * src/symtab.h: Prototype all those new functions.
6559 * tests/actions.at (Default %printer and %destructor): New test to
6560 check that the right %printer and %destructor are called, that they're
6561 not called for $end, and that $$ and @$ work correctly.
6562 (Default %printer and %destructor for user-declared end token): New
6563 test to check that the default %printer and %destructor are called for
6564 a user-declared end token.
6565 * tests/input.at (Default %printer and %destructor redeclared, Unused
6566 values with default %destructor): New tests to check related grammar
6567 warnings and errors.
6568
65692006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6570
6571 Clean up handling of %destructor for the end token (token 0).
6572 Discussed starting at
6573 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
6574 and
6575 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
6576
6577 Make the skeletons consistent in how they pop the end token and invoke
6578 its %destructor.
6579 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
6580 state, which has token number 0, since this would invoke the
6581 %destructor for the end token.
6582 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
6583 until after shifting the end token, or else it won't be popped.
6584 * data/yacc.c (yyparse): Likewise.
6585
6586 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
6587 it's the end token. Upon termination, destroy an unshifted lookahead
6588 even when it's the end token.
6589 * data/lalr1.cc (yy::parser::parse): Likewise.
6590 * data/yacc.c (yyparse): Likewise.
6591
6592 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
6593 value warnings for the end token when the user gives the end token a
6594 %destructor.
6595
6596 * tests/actions.at (Printers and Destructors): Test all the above.
6597
65982006-07-24 Paul Eggert <eggert@cs.ucla.edu>
6599
6600 Update to latest gnulib and gettext versions.
6601 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
6602 Add fopen-safer.
6603 (gnulib_files): Add m4/warning.m4. Don't worry about files
6604 overwritten by autopoint.
6605 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
6606 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
6607 rejects them.
6608 Don't use autoreconf; instead, invoke autopoint etc. by hand,
6609 so that we can remove the intl files at a better time.
6610 (intl_files_to_remove): Remove aclocal.m4, since it gets
6611 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
6612 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
6613 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
6614 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
6615 Remove datarootdir hack; no longer needed.
6616 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
6617 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
6618 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
6619 strdup.h.
6620 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
6621 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
6622
66232006-07-20 Paul Eggert <eggert@cs.ucla.edu>
6624
6625 * bootstrap: Adjust to today's change to gnulib-tool by invoking
6626 it with --assume-autoconf='latest-stable'.
6627
66282006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
6629
6630 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
6631 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
6632 YYSTYPE' and `{'.
6633 * src/muscle_tab.h (muscle_grow): Replace the header comments with
6634 those from muscle_tab.c since the old ones are misleading.
6635
66362006-07-13 Akim Demaille <akim@epita.fr>
6637
6638 Support %define "KEY" {VALUE}.
6639 * src/scan-code.h, src/scan-code.l (translate_action)
6640 (translate_rule_action, translate_symbol_action, translate_code):
6641 Return char *, not const char *.
6642 * src/parse-gram.y (declaration): Rename as...
6643 (prologue_declaration): this.
6644 (string_content): Remove this nonterminal, use STRING.
6645 (braceless, content, content.opt): New nonterminal.
6646 Use them.
6647 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
6648 as value.
6649 * src/scan-gram.l (getargs.h): Don't include it.
6650
66512006-07-12 Paul Eggert <eggert@cs.ucla.edu>
6652
6653 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
6654 rather than a for-loop that declares a local bool variable. This
6655 should work around a compatibility problem with a Cray x1e C++
6656 compiler reported by Hung Nguyen in
6657 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
6658 The for-loop was introduced in the 2004-11-17 change but I don't
6659 know why it was needed.
6660
66612006-07-12 Akim Demaille <akim@epita.fr>
6662
6663 * data/c.m4: Comment changes.
6664
66652006-07-10 Akim Demaille <akim@lrde.epita.fr>
6666
6667 * src/complain.c (error_message, ERROR_MESSAGE): New.
6668 To factor...
6669 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
6670 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
6671
66722006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6673
6674 * NEWS: Instead of %union, you can define and use your own union type
6675 YYSTYPE if your grammar contains at least one <type> tag.
6676 Your YYSTYPE need not be a macro; it can be a typedef.
6677 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
6678 (Union Decl, Decl Summary): Document this.
6679 * data/glr.c (YYSTYPE): Implement this.
6680 * data/glr.cc (YYSTYPE): Likewise.
6681 * data/lalr1.cc (YYSTYPE): Likewise.
6682 * data/yacc.c (YYSTYPE): Likewise.
6683 * src/output.c (prepare): Output tag_seen_flag.
6684 * src/parse-gram.y (declaration, grammar_declaration):
6685 Use 'union_seen' rather than 'typed' to determine whether
6686 %union has been seen, since grammars can now be typed without
6687 %union.
6688 (symbol_declaration, type.opt, symbol_def):
6689 Keep track of whether a tag has been seen.
6690 * src/reader.c (union_seen, tag_seen): New vars.
6691 (typed): remove.
6692 * src/reader.h (union_seen, tag_seen, typed): Likewise.
6693 * src/scan-code.l (untyped_var_seen): New variable.
6694 (handle_action_dollar): Adjust to above changes.
6695 (handle_action_dollar, handle_action_at):
6696 Improve overflow checking for outlandish numbers.
6697 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
6698 avoid new diagnostics generated by above changes.
6699 * tests/regression.at (YYSTYPE typedef): Add test to check
6700 for type tags without %union.
6701
6702 * src/symlist.c (symbol_list_length): Return int, not unsigned
6703 int, since callers expect int. This may need to get revisited
6704 once we have proper integer overflow checking.
6705
6706 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
6707 object is now static.
6708
6709 * src/getargs.c (flags_argmatch): Return void, not int,
6710 to pacify ./configure --enable-gcc-warnings.
6711
6712 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
6713 since last_string is already defined to FLEX_PREFIX (last_string).
6714
67152006-07-09 Akim Demaille <akim@lrde.epita.fr>
6716
6717 Implement --warnings/-W.
6718 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
6719 replaced by...
6720 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
6721 Adjust callers.
6722 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
6723 (warnings_args, warnings_types): New.
6724 (getargs, short_options, long_options): Accept -W/--warnings.
6725 Sort the options by alphabetical order, upper case letter right
6726 before its lower case.
6727
67282006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6729
6730 Change %merge result type clash warnings to errors. Discussed at
6731 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
6732 * src/reader.c (record_merge_function_type): Use complain_at.
6733 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6734 declared later): Update test case results.
6735
67362006-07-09 Akim Demaille <akim@lrde.epita.fr>
6737
6738 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
6739 to be in alphabetical order.
6740 (trace_args): Spelling fixes.
6741
67422006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6743
6744 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
6745 so they don't collide with user-defined macros.
6746 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
6747 this was never guaranteed, and now that we're using gnulib stdint,
6748 which defines int_fast16_t to long int, the problem is exposed.
6749
67502006-07-08 Paul Eggert <eggert@cs.ucla.edu>
6751
6752 * data/c.m4 (b4_basename): Simplify a bit, since we don't
6753 need the full POSIX semantics (and weren't implementing them
6754 anyway).
6755
6756 Adjust to Autoconf 2.60 and today's gnulib.
6757 * bootstrap (gnulib_modules): Add stdint.
6758 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
6759 no longer copies it.
6760 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6761 since stdint needs the former and wcwidth (which is now required
6762 by mbswidth) needs the latter.
6763 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6764 work around a compatibility glitch between gettext 0.14.6 and
6765 Autoconf 2.60.
6766 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
6767 Do not check for uintptr_t, since new stdint module does the right
6768 thing.
6769 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
6770 Add stdint.h, stdint_.h, wcwidth.h.
6771 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
6772 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
6773 stdint.m4, wchar_t.m4, wcwidth.m4.
6774 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
6775 usual order for ../lib/*.h files.
6776 (file_name_split): Use last_component, not base_name, to adjust
6777 to gnulib changes.
6778 * src/parse-gram.h: Include <strverscmp.h> in the usual order
6779 for ../lib/*.h files.
6780 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
6781 Define unconditionally, since we now assume the stdint module.
6782 * src/scan-skel.l: Include <dirname.h>.
6783 (BASE_QPUTS): Use last_component, not base_name.
6784 * src/system.h: Include <unlocked-io.h> in the usual order
6785 for ../lib/*.h files. Include <stdint.h> unconditionally,
6786 since we now use the stdint module.
6787 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
6788 HAVE_UINTPTR_T, since we now use the stdint module.
6789 (base_name): Remove decl, since files now include <dirname.h>
6790 to get the decl.
6791
67922006-07-08 Akim Demaille <akim@lrde.epita.fr>
6793
6794 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
6795 New, default to 1.
6796 * data/yacc.c, data/glr.c, data/location.cc: Use them.
6797 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
6798 default.
6799 * tests/calc.at: Adjust.
6800
68012006-07-08 Akim Demaille <akim@lrde.epita.fr>
6802
6803 * data/c.m4 (b4_basename): New.
6804 (b4_syncline): Also output the location of its invocation (from
6805 the skeleton).
6806 (b4_user_action, b4_define_user_action, b4_user_actions)
6807 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
6808 (b4_user_stype): New.
6809 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
6810
68112006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6812
6813 In the grammar file, the first column is 1 not 0 on the first line as
6814 on every other line.
6815 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
6816 * tests/input.at (Torturing the Scanner): Update output.
6817
6818 * src/scan-gram.l (scanner_cursor): Declare it static.
6819
68202006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6821
6822 In warnings, say "previous declaration" rather than "first
6823 declaration".
6824 * src/symtab.c (redeclaration): Do that here.
6825 * src/reader.c (record_merge_function_type): In the case of a result
6826 type clash, report the previous declaration rather than the very first
6827 one in the grammar file.
6828 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6829 declared later): Add a third declaration to check this behavior.
6830 * tests/input.at (Incompatible Aliases): Update output.
6831
68322006-06-27 Akim Demaille <akim@epita.fr>
6833
6834 * doc/Doxyfile.in: New.
6835 * doc/Makefile.am: Use it.
6836 * src/lalr.h, src/symtab.h: Initial doxygenation.
6837
68382006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6839
6840 Don't miss %merge result type warnings just because the LHS types are
6841 declared after the %merge. This continues the effort of the previous
6842 patch.
6843 * src/reader.c (get_merge_function): Don't set the merger type yet.
6844 (record_merge_function_type): New function for setting the merger type
6845 and checking for clashes.
6846 (grammar_current_rule_merge_set): Set the location of the %merge for
6847 the current rule.
6848 (packgram): Invoke record_merge_function_type for each rule now that
6849 all symbol type declarations have been parsed.
6850 * src/reader.h (merger_list.type_declaration_location): New member
6851 storing the location of the first %merge from which the type for this
6852 merging function was derived.
6853 * src/symlist.h (symbol_list.merger_declaration_location): New member
6854 storing the location of a rule's %merge, if any.
6855 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6856 declared later): New test to catch the error fixed by the above patch.
6857
68582006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6859
6860 Get action warnings (grammar_rule_check) right even when symbol
6861 declarations appear after the rules. Discussed at
6862 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
6863 and
6864 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
6865 Don't mistake the type of $$ in a midrule to be that of its parent
6866 rule's $$.
6867 * src/reader.c (grammar_current_rule_end): Don't invoke
6868 grammar_rule_check yet since not all symbol declarations may have been
6869 parsed yet.
6870 (grammar_midrule_action): Likewise.
6871 Don't record whether the midrule's $$ has been used yet since actions
6872 haven't been translated yet.
6873 Record the midrule's parent rule and its RHS index within the parent
6874 rule.
6875 (grammar_current_rule_action_append): Don't translate the action yet
6876 since not all symbol declarations may have been parsed yet and, thus,
6877 warnings about types for $$, $n, @$, and @n can't be reported yet.
6878 (packgram): Translate the action and invoke grammar_rule_check now that
6879 all symbol declarations have been parsed.
6880 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6881 after parsing the entire grammar file, the symbol list here in the case
6882 of a midrule is actually the midrule's empty RHS, so reference its
6883 parent rule's RHS where necessary.
6884 On the other hand, now that you can already know it's a midrule, you
6885 aren't forced to think $$ has the same type as its parent rule's $$.
6886 (handle_action_at): In the case of a midrule, reference the parent rule
6887 where necessary.
6888 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6889 members.
6890 (symbol_list_length): Now that this is invoked after all rules have
6891 been parsed, a NULL symbol (rather than a NULL symbol list node)
6892 terminates a rule. symbol_list_print already does this correctly.
6893 * src/symlist.h (symbol_list.midrule_parent_rule,
6894 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6895 remember their relationships with their parents.
6896 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6897 fixed by the above patch.
6898 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6899 implementing...
6900 (Unused values): ... this old test case and...
6901 (Unused values before symbol declarations): ... this new test case.
6902 This one is the same as `Unused values' except that all symbol
6903 declarations appear after the rules in order to catch the rest of the
6904 errors fixed by the above patch.
6905
69062006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6907
6908 More cleanup.
6909 * src/reader.c (current_rule): Declare it static since it's no longer
6910 used outside this file.
6911 (grammar_current_rule_action_append): Remove redundant arguments from
6912 translate_rule_action invocation.
6913 * src/reader.h (current_rule): Remove this unused extern.
6914 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
6915 * src/scan-code.l (translate_rule_action): Likewise.
6916
69172006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
6918
6919 Clean up yesterday's patch.
6920 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
6921 to...
6922 * src/reader.c (grammar_current_rule_action_append): ... here for
6923 consistency with grammar_current_rule_symbol_append.
6924 * tests/regression.at (Braced code in declaration in rules section):
6925 Make yyerror and yylex static as usual.
6926
69272006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
6928
6929 Fix bug that mistakes braced code in a declaration in the rules section
6930 to be a rule action. Mentioned at
6931 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
6932 * src/scan-gram.l: Move midrule action detection from the start of the
6933 scanning of any braced code to...
6934 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
6935 action. For readability, use $2 and @2 rather than the equivalent
6936 global variables.
6937 * tests/regression.at (Braced code in declaration in rules section):
6938 New test to catch the error fixed by the above patch.
6939
6940 Work on code readability some.
6941 * src/scan-code.l (current_rule): Get rid of this misleading and
6942 redundant declaration: it's actually extern'ed in reader.h.
6943 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
6944 translate_action): Add a rule argument and use it instead of the global
6945 current_rule.
6946 (translate_rule_action): This already receives current_rule through an
6947 argument, so pass it on to translate_action instead of assigning
6948 current_rule to current_rule.
6949 (translate_symbol_action, translate_code): Pass rule = NULL to
6950 translate_action.
6951
69522006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
6953
6954 Rename %before-definitions to %start-header and %after-definitions to
6955 %end-header. Don't use these declarations to separate pre-prologue
6956 blocks from post-prologue blocks. Add new order-independent
6957 declarations %before-header and %after-header as alternatives to the
6958 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
6959 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
6960 * NEWS (2.3+): Update for these changes.
6961 * data/glr.c (b4_before_definitions): Update to...
6962 (b4_start_header): ... this.
6963 (b4_after_definitions): Update to...

6965 * data/glr.cc: Likewise.
6966 * data/lalr1.cc: Likewise.
6967 * data/yacc.c: Likewise.
6968 * doc/bison.texinfo (The prologue): Update names, and replace remaining
6969 prologue blocks with %*-header declarations.
6970 (Calc++ Parser): Likewise.
6971 (Decl Summary): Update names.
6972 (Table of Symbols): Update description.
6973 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
6974 (PERCENT_END_HEADER): ... this.
6975 (PERCENT_BEFORE_DEFINITIONS): Update to...
6976 (PERCENT_START_HEADER): ... this.
6977 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6978 (declaration): Update token names and m4 macro names.
6979 When parsing %end-header and %start-header, invoke translate_code
6980 before muscle_code_grow, and no longer set global booleans to remember
6981 whether these declarations have been seen.
6982 Parse new %after-header and %before-header.
6983 * src/reader.c (before_definitions, after_definitions): Remove.
6984 (prologue_augment): Accept a new bool argument to specify whether to
6985 augment the pre-prologue or post-prologue.
6986 * src/reader.h (before_definitions, after_definitions): Remove these
6987 extern's.
6988 (prologue_augment): Add new bool argument.
6989 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
6990 (PERCENT_END_HEADER): ... this.
6991 (PERCENT_BEFORE_DEFINITIONS): Update to...
6992 (PERCENT_START_HEADER): ... this.
6993 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6994 * tests/actions.at (Printers and Destructors): Update names.
6995
69962006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
6997
6998 Add comparison operators for C++ location classes. Discussed at
6999 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
7000 * data/c++.m4 (b4_define_location_comparison): New boolean %define
7001 declaration indicating whether filename_type has an operator==. If
7002 filename_type is `std::string', it defaults to `1', `0' otherwise.
7003 * data/location.cc: Iff b4_define_location_comparison is `1', add
7004 operator== and operator!= for class position and for class location.
7005
7006 Some minor fixes.
7007 * src/scan-action.l: Remove unused file.
7008 * src/symtab.c (symbol_printer_set): Use printer_location not
7009 destructor_location.
7010 * src/symtab.h (struct symbol): Replace incorrect source comment for
7011 printer members.
7012 * tests/input.at (Incompatible Aliases): Update output with correct
7013 printer location.
7014
70152006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
7016
7017 Don't put the pre-prologue in the header file. For the yacc.c code
7018 file and the glr.c header and code files, move the pre-prologue before
7019 the token definitions. Add new %before-definitions and
7020 %after-definitions to declare code that will go in both the header file
7021 and code file. Discussed at
7022 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
7023 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
7024 and
7025 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
7026 * NEWS (2.3+): Describe these changes.
7027 * data/glr.c (b4_pre_prologue): Move from within to before...
7028 (b4_shared_declarations): ... this.
7029 Add new b4_before_definitions before b4_token_enums.
7030 Add new b4_after_definitions at the end.
7031 * data/glr.cc (b4_pre_prologue): Replace with...
7032 (b4_before_definitions): ... this in the header file.
7033 (b4_after_definitions): New near the end of the header file.
7034 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
7035 code file right before including the header file.
7036 (b4_before_definitions): New in the previous position of
7037 b4_pre_prologue in the header file.
7038 (b4_after_definitions): New near the end of the header file.
7039 * data/yacc.c: Clean up some m4 quoting especially in the header file.
7040 (b4_token_enums_defines): In the code file, move to right before
7041 YYSTYPE for consistency with the header file.
7042 (b4_before_definitions): New right before b4_token_enums_defines in
7043 both the header and code file.
7044 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
7045 header and code file.
7046 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
7047 of prologues for %union dependencies.
7048 (Decl Summary): In %defines description, mention the effect of
7049 %before-definitions and %after-definitions on the header file.
7050 (Calc++ Parser): Forward declare driver in a %before-definitions rather
7051 than in the pre-prologue so that make check succeeds.
7052 (Table of Symbols): Add entries for %before-definitions and
7053 %after-definitions.
7054 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
7055 %before-definitions.
7056 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
7057 (declaration): Parse those declarations and append to
7058 b4_before_definitions and b4_after_definitions, respectively.
7059 * src/reader.c (before_definitions, after_definitions): New bools to
7060 track whether those declarations have been seen.
7061 (prologue_augment): Add to the post-prologue if %union,
7062 %before-definitions, or %after-definitions has been seen.
7063 * src/reader.h (before_definitions, after_definitions): New extern's.
7064 * src/scan-gram.l: Scan the new declarations.
7065 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
7066 prologue block in a %before-definitions or a %after-definitions based
7067 on whether the %union is declared.
7068 * tests/regression.at (Early token definitions with --yacc, Early token
7069 definitions without --yacc): Move tests for token definitions into the
7070 post-prologue since token names are no longer defined in the
7071 pre-prologue.
7072
70732006-06-20 Akim Demaille <akim@epita.fr>
7074
7075 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
7076 (symbol_get): Use it.
7077 * src/parse-gram.y: Use it.
7078
70792006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
7080
7081 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
7082 build succeeds when configured with --enable-gcc-warnings.
7083
70842006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7085
7086 * src/parse-gram.y (char_name): New function.
7087 (CHAR, STRING, string_content): For %printer, properly escape.
7088 (ID): Prefer fputs to fprintf.
7089 (id): Reindent to be consistent with other rules.
7090 Properly quote char.
7091
7092 The Translation Project changed its way of publishing translations
7093 to maintainers. I haven't received any responses to my request
7094 for supporting the old way, or for documenting the new way. I
7095 have modified 'bootstrap' to use screen scraping
7096 (in this case, HTML scraping). This is unreliable and inelegant,
7097 but I don't see any better way. Yuck.
7098 * bootstrap (TP_URL, WGET_COMMAND): New vars.
7099 (get_translations): New function, which uses HTML scraping to
7100 deduce locations of latest translations.
7101 Use this function to grab both bison and bison-runtime .po files.
7102 Don't bother priming the pump for the runtime-po domain any more,
7103 as it's now translated better than bison is.
7104
71052006-06-19 Akim Demaille <akim@epita.fr>
7106
7107 * src/scan-gram.l: No longer "parse" things after `%union' until
7108 `{'. Rather, return a single "%union" token.
7109 No longer make symbols: return strings, and leave the conversion
7110 to symbols to the parser.
7111 (SC_PRE_CODE, token_type): Remove.
7112 * src/parse-gram.y (%union): New field `character'.
7113 Sort tokens.
7114 (CHAR): New token.
7115 (ID, ID_COLON): Now that the scanner no longer makes them
7116 identifiers, adjust all uses to invoke symbol_get.
7117 (id_colon): New, wraps the conversion from string to symbol.
7118 (%union): Accept a possible union_name.
7119 (symbol): Now can be a char.
7120 * data/c.m4 (b4_union_name): Leave a default value.
7121 * data/glr.c, data/yacc.c: Use it.
7122
71232006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
7124
7125 For associating token numbers with token names for "yacc.c", don't use
7126 #define statements unless `--yacc' is specified; always use enum
7127 yytokentype. Most important discussions start at:
7128 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
7129 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
7130 and
7131 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
7132 * NEWS (2.3+): Mention.
7133 * data/c.m4 (b4_yacc_if): New.
7134 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
7135 token #define's.
7136 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
7137 on token name definitions.
7138 * src/getargs.c (usage): Capitalize `Yacc' in English.
7139 * src/output.c (prepare): Define b4_yacc_flag.
7140 * tests/regression.at (Early token definitions): Test that tokens names
7141 are defined before the pre-prologue not just before the post-prologue.
7142 Remove this test case and copy to...
7143 (Early token definitions with --yacc): ... this to test #define's.
7144 (Early token definitions without --yacc): ... and this to test enums.
7145
71462006-06-11 Paul Eggert <eggert@cs.ucla.edu>
7147
7148 * NEWS: Reword the post-2.3 change to not be so optimistic about
7149 removing the old "look-ahead" spelling.
7150 Update previous look-ahead/lookahead change reports.
7151 * REFERENCES: look-ahead -> lookahead (since that's
7152 what he actually wrote).
7153 * doc/refcard.tex: look ahead -> lookahead,
7154 look-ahead -> lookahead
7155
71562006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
7157
7158 For consistency, use `lookahead' instead of `look-ahead' or
7159 `look_ahead'. Discussed starting at
7160 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
7161 and then at
7162 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

7234
7235 * TODO: Add request from Nelson H. F. Beebe to be able to install
7236 Bison without installing the yacc script.
7237
72382006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
7239
7240 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
7241 and yytext if they're already #define'd.
7242 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
7243 * src/scan-code-c.c: ... here.

7245 <config.h>.
7246
72472006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
7248
7249 Get Bison to build again when configured with --enable-gcc-warnings.
7250 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
7251 missing #include's.
7252 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
7253 loc argument as it shadows a global.
7254 * src/scan-gram.l: Remove stray comma that prevents boundary_set
7255 invocation.
7256
7257 * src/.cvsignore: Add scan-code.c.
7258
72592006-06-07 Akim Demaille <akim@epita.fr>
7260
7261 * src/scan-gram.l: Move the "add a trailing ; to actions" code
7262 to...
7263 * src/scan-code.l: here.
7264 * tests/input.at (Torturing the Scanner): Fix another location
7265 error.
7266
72672006-06-07 Akim Demaille <akim@epita.fr>
7268
7269 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
7270
72712006-06-06 Akim Demaille <akim@epita.fr>
7272
7273 Extract the parsing of user actions from the grammar scanner.
7274 As a consequence, the relation between the grammar scanner and
7275 parser is much simpler. We can also split "composite tokens" back
7276 into simple tokens.
7277 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
7278 * src/scan-gram.l (add_column_width, adjust_location): Move to and
7279 rename as...
7280 * src/location.h, src/location.c (add_column_width)
7281 (location_compute): these.
7282 Fix the column count: the initial column is 0.
7283 (location_print): Be robust to ending column being 0.
7284 * src/location.h (boundary_set): New.
7285 * src/main.c: Adjust to scanner_free being renamed as
7286 gram_scanner_free.
7287 * src/output.c: Include scan-code.h.
7288 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
7289 Use boundary_set.
7290 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
7291 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
7292 which is now, again, a separate token.
7293 Adjust all dependencies.
7294 Whereever actions with $ and @ are used, use translate_code.
7295 (action): Remove this nonterminal which is now useless.
7296 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
7297 (grammar_current_rule_action_append): Use translate_code.
7298 (packgram): Bound check ruleno, itemno, and rule_length.
7299 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
7300 (last_string, last_braced_code_loc, max_left_semantic_context)
7301 (scanner_initialize, scanner_free, scanner_last_string_free)
7302 (gram_out, gram_lineno, YY_DECL_): Move to...
7303 * src/scan-gram.h: this new file.
7304 (YY_DECL): Rename as...
7305 (GRAM_DECL): this.
7306 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
7307 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7308 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7309 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7310 Move these declarations, and...
7311 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
7312 these to...
7313 * src/flex-scanner.h: this new file.
7314 * src/scan-gram.l (rule_length, rule_length_overflow)
7315 (increment_rule_length): Remove.
7316 (last_braced_code_loc): Rename as...
7317 (gram_last_braced_code_loc): this.
7318 Adjust to the changes of the parser.
7319 Move all the handling of $ and @ into...
7320 * src/scan-code.l: here.
7321 * src/scan-gram.l (handle_dollar, handle_at): Remove.
7322 (handle_action_dollar, handle_action_at): Move to...
7323 * src/scan-code.l: here.
7324 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
7325 scan-code.h, scan-code-c.c, scan-gram.h.
7326 (EXTRA_bison_SOURCES): Add scan-code.l.
7327 (BUILT_SOURCES): Add scan-code.c.
7328 (yacc): Be robust to white spaces.

7331 * tests/regression.at: Adjust the column numbers.
7332 * tests/regression.at: Adjust the error message.
7333
73342006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7335
7336 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7337 Use Akim's wording from
7338 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
7339
73402006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7341
7342 Between Bison releases, manually append `+' to the previous Bison
7343 release number, and use that as a signal to automatically print the
7344 ChangeLog's CVS Id keyword from --version. Discussed starting at
7345 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
7346 * ChangeLog: Add Id header.
7347 * configure.ac (AC_INIT): Append `+' to `2.3'.
7348 * src/.cvsignore: Add revision.c.
7349 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
7350 (BUILT_SOURCES): Add revision.c.
7351 (revision.c): New target rule. This file defines a new global variable
7352 named revision. It initializes it with either the Id from ChangeLog
7353 or, if VERSION doesn't contain `+', with the empty string.
7354 * src/getargs.c (version): Print the value of revision.
7355 * src/revision.h: Extern revision.

7359 * NEWS: Version 2.3.
7360 * configure.ac (AC_INIT): Likewise.
7361
73622006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7363
7364 * data/glr.c (YYRECOVERING): Define to be a function-like macro
7365 with no arguments, not as an object-like macro. This is for
7366 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
7367 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
7368 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
7369 Document this.
7370
73712006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
7372
7373 * src/getargs.c (usage): Back out yesterday's modification of the
7374 --help output so that we don't have to wait for translation before
7375 releasing 2.3.
7376
73772006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7378
7379 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
7380 Problem reported by Akim Demaille.
7381
73822006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
7383
7384 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7385
73862006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7387
7388 * data/yacc.c (yy_reduce_print): Omit trailing white space in
7389 generated source code. Problem reported by Frans Englich in
7390 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7391
73922006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7393
7394 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7395 shell, not within 'make', so that 'make' by an ordinary builder
7396 (using GNU make) does not worry about configuring gzip. This also
7397 works around a bug reported independently by Keith Thompson and by
7398 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7399 stderr rather than stdout, messing up the build logs.
7400
74012006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7402
7403 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7404 to make sure that YYID will never be unused. This fixes a 'make
7405 maintainer-check' failure caused by the recent changes to the 'Trivial
7406 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7407 not used.
7408 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7409
74102006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7411
7412 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7413 state before an empty RHS is always resolved here. Only the location
7414 of that state is guaranteed to be resolved, and that's enough. This
7415 fixes the remaining bug reported by Derek M. Jones in
7416 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7417 * tests/glr-regression.at (Uninitialized location when reporting
7418 ambiguity): Test the above case.
7419 Also, the embedded comments in this test case claim it checks the case
7420 of an empty RHS that has inherited the initial location. However, the
7421 corresponding LHS was already resolved, so yyresolveLocations didn't
7422 actually have reason to modify it. Fix this by forcing
7423 nondeterministic operation at the beginning of the parse.
7424
74252006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7426
7427 * data/c.m4 (b4_yy_symbol_print_generate):
7428 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7429 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7430 of the bugs reported today by Derek M Jones in
7431 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7432 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7433 defined to be a type name without parens or brackets.
7434 (Location Type): Similarly for YYLTYPE.
7435 * tests/regression.at (Trivial grammars): Put in a test for this
7436 bug that will be caught by 'make maintainer-check' (though not,
7437 alas, by 'make check' unless your compiler is picky).
7438
74392006-05-19 Paul Eggert <eggert@cs.ucla.edu>
7440
7441 * NEWS: Version 2.2.
7442 * configure.ac (AC_INIT): Likewise.
7443
74442006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
7445
7446 * data/glr.c (yyreportTree): Make room in yystates for the state
7447 preceding the RHS. This fixes the segmentation fault reported by Derek
7448 M. Jones in
7449 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7450 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7451 to the user. Reported for yyreportTree by Derek M. Jones later in the
7452 same thread.
7453 * THANKS: Add Derek M. Jones.
7454 Update my email address.
7455 Fix typo in Steve Murphy's name.
7456
74572006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7458
7459 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7460 checking against YYLAST that caused the parser to miss a potential
7461 alternative in its diagnostic.
7462 Problem reported by Maria Jose Moron Fernandez in
7463 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
7464 * data/lalr1.cc (yysyntax_error_): Likewise.
7465 * data/yacc.c (yysyntax_error): Likewise.
7466 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7467 tokens, in case we run into an older C compiler.
7468 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7469 Use them to check for the off-by-one error fixed above.
7470
7471 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7472 YYSIZE_T, not size_t.
7473 * tests/regression.at (Trivial grammars): New test, to catch
7474 the error fixed by the above patch.
7475
74762006-05-14 Akim Demaille <akim@lrde.epita.fr>
7477
7478 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7479 scheme.
7480 Reported by Steve Murphy.
7481
74822006-05-14 Akim Demaille <akim@lrde.epita.fr>
7483
7484 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7485 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7486
74872006-05-14 Akim Demaille <akim@lrde.epita.fr>
7488
7489 Implement --trace=m4.
7490 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7491 * src/output.c (output_skeleton): When set, pass -dV to m4.
7492
7493 Factor the handling of flags in m4.
7494 * src/output.c (prepare): Rename the muscle names debug, defines,
7495 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7496 * data/c.m4: Adjust.
7497 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7498 Use b4_define_flag_if to define other b4_FLAG_if macros.
7499 (b4_location_if): As a consequence, rename as...
7500 (b4_locations_if): this, for consistency.
7501 Adjust all the skeletons.
7502
75032006-05-14 Akim Demaille <akim@lrde.epita.fr>
7504
7505 * etc/bench.pm: Shorten bench names.

75072006-05-14 Akim Demaille <akim@lrde.epita.fr>
7508
7509 * src/output.h, src/output.c (error_verbose): Move to...
7510 * src/getargs.h, src/getargs.c: here.
7511 Sort the flags.
7512 Adjust dependencies.
7513
75142006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7515
7516 * data/c.m4 (b4_copyright): Put the special exception for Bison
7517 skeletons here, so we don't have to put it in each skeleton. All
7518 uses changed. Suggested by Akim Demaille. Also, wrap the
7519 copyright notice, in case it is longer than 80 columns. Replace
7520 comma by newline after title.
7521
75222006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7523
7524 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7525 incompatibility, not a bug. Mention that it wasn't fixed as of
7526 flex 2.5.33.
7527
75282006-05-11 Akim Demaille <akim@lrde.epita.fr>
7529
7530 * examples/extexi: Enforce the precedence of concatenation over
7531 >>.
7532 Reported by Tommy Nordgren.
7533
75342006-05-11 Akim Demaille <akim@lrde.epita.fr>
7535
7536 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7537 with the member "token".
7538 Reported by Martin Nylin.
7539
75402006-05-08 Paul Eggert <eggert@cs.ucla.edu>
7541
7542 * data/glr.c: Switch to Bison 2.2 special-exception language in
7543 the copyright notice. Use more-regular format for titles and
7544 copyright notices.
7545 * data/glr.cc: Likewise.
7546 * data/location.cc: Likewise.
7547 * data/yacc.cc: Likewise.

7553 * data/glr.cc: Remove dead code.
7554
75552006-04-25 Paul Eggert <eggert@cs.ucla.edu>
7556
7557 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
7558 that variable and the line breaks the bootstrap. Problem reported
7559 by Juan M. Guerrero.
7560
75612006-04-24 Akim Demaille <akim@lrde.epita.fr>
7562

7572 rule.
7573 Reported by Mickael Labau.

75812006-03-13 Paul Eggert <eggert@cs.ucla.edu>
7582
7583 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
7584 and didn't really work.
7585 For the index, use @ifnotinfo, not @iftex.
7586 Minor cleanups of spacing and terminology.
7587

7592
75932006-03-12 Akim Demaille <akim@lrde.epita.fr>
7594
7595 Apply --prefix to C++ skeletons too: they change the namespace.
7596 The test suite already exercize these cases.
7597 * data/c++.m4 (b4_namespace): New.
7598 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.

7600 * data/yacc.c, data/glr.c: Remove a useless `[]'.
7601 * doc/bison.texinfo: Document it.
7602 (Option Cross Key): Use @multitable in all formats. It looks
7603 nicer, even in TeX outputs.
7604 (Rules): Use the same code whatever the output type is.

7627
7628 Fix two nits reported by twlevo, plus one more that I discovered.
7629
7630 * src/assoc.h (assoc_to_string): Give a name to the arg, as
7631 this is the usual Bison style.
7632 * src/location.h (location_print): Likewise.

7637
7638 Fix some nits reported by twlevo.
7639 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
7640 and "POSIX". Use more-modern syntax for URLs. Mention C++
7641 and ask for Java. Don't hardwire OS version numbers. Add
7642 copyright notice.
7643 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
7644 * src/conflicts.c (solved_conflicts_obstack): Now static.
7645

7647
7648 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
7649 page. Say "you can use it" not "you may use it" as on the web page;
7650 we're describing capabilities not granting permission.
7651
76522006-03-06 Paul Eggert <eggert@cs.ucla.edu>
7653
7654 * data/glr.c (yyresolveLocations): Rename local variables to avoid
7655 shadowing warnings. Use usual patter for iterating through RHS.
7656 * tests/glr-regression.at
7657 (Uninitialized location when reporting ambiguity):
7658 Modify yylex so that it uses its argument, rather than trying
7659 to rely on ARGSUSED (which doesn't work for gcc with warnings).
7660 const char -> char const.
7661
7662 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
7663 Don't use tabs inside commands; it messes up 'ps'.

7671 YYLLOC_DEFAULT.
7672 (yyresolveValue): Invoke yyresolveLocations before reporting an
7673 ambiguity.
7674 * doc/bison.texinfo (Default Action for Locations): Note
7675 YYLLOC_DEFAULT's usage for ambiguity locations.
7676 (GLR Semantic Actions): Cross-reference those notes.
7677
76782006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
7679
7680 * tests/glr-regression.at (Leaked semantic values when reporting
7681 ambiguity): Remove unnecessary union and type declarations.
7682 (Leaked lookahead after nondeterministic parse syntax error): New test
7683 case.
7684 * data/glr.c (yyparse): Check for zero stacks remaining before
7685 attempting to shift the lookahead so that you don't lose it.

7689 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
7690 * tests/glr-regression.at (Leaked semantic values when reporting
7691 ambiguity): New test case.
7692 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
7693 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
7694 now unnecessary yystackp parameter.
7695 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
7696 destructors can be called.
7697
7698 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
7699 in existing testcases.

7702
7703 Don't leak semantic values for parent RHS when a user action cuts the
7704 parser, and clean up related code a bit.
7705 * tests/glr-regression.at (Leaked merged semantic value if user action
7706 cuts parse): Rename to...
7707 (Leaked semantic values if user action cuts parse): ... this. Add check
7708 for leaked parent RHS values.
7709 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
7710 between an unresolved state (non-empty chain of semantic options) and
7711 an incomplete one (signaled by an empty chain).
7712 (yyresolveStates): Document the interface. Move all manipulation of a
7713 successfully or unsuccessfully resolved yyGLRState to...
7714 (yyresolveValue): ... here so that yyresolveValue always leaves a
7715 yyGLRState with consistent data and thus is easier to understand.
7716 Remove the yyvalp and yylocp parameters since they are always just
7717 taken from the yys parameter. When reporting a discarded merged value
7718 in debugging output, note that it is incompletely merged. Document the
7719 interface.
7720 (yyresolveAction): If resolving any of the RHS states fails, destroy
7721 them all rather than leaking them. Thus, as long as user actions are
7722 written to clean up the RHS correctly, yyresolveAction always cleans up
7723 the RHS of a semantic option. Document the interface.

7742 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||

7778 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

7788
7789 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
7790 nodist_PROGRAMS, since we don't need to actually compile the
7791 example if we're just doing a plain 'make'. This avoids bothering
7792 the installer unnecessarily about problems due to weird C++
7793 compilers.

7800 than #include "...", and compile with -I'.'. The old method was
7801 not portable, according to Posix and the C standard, and it does
7802 not work with Sun C 5.7, where previous #line directives affect
7803 the working directory used in later #include "..." directives.

7822 that '#include <string>' works.
7823
7824 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
7825 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
7826 "warning: sorry: semantics of inline function static data `const
7827 unsigned char translate_table[262]' are wrong (you'll wind up with
7828 multiple copies)".
7829
7830 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
7831 or, xor to not_, and_, or_, and xor_, respectively. This works
7832 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
7833 random system header somewhere that includes the equivalent of
7834 <iso646.h>.
7835

7841
7842 During deterministic GLR operation, user actions should be able to
7843 influence the parse by changing yychar. To make this easier to fix and
7844 to make glr.c easier to evolve in general, don't maintain yytoken in
7845 parallel with yychar; just compute yytoken when needed.
7846 * tests/glr-regression.at (Incorrect lookahead during deterministic
7847 GLR): Check that setting yychar in a user action has the intended
7848 effect.
7849 * data/glr.c (yyGLRStack): Remove yytokenp member.
7850 (yyclearin): Don't set *yytokenp.
7851 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
7852 yychar rather than *yytokenp to determine the current lookahead.
7853 Compute yytoken locally when needed.
7854 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
7855 point to.
7856
7857 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
7858 after `--report' documentation.

7862 * src/parse-gram.y (grammar_declaration): Location of printer
7863 symbol is @1, not list->location. Bug reported by twlevo.
7864 * tests/input.at (Incompatible Aliases): Adjust to above change.
7865
78662006-01-29 Paul Eggert <eggert@cs.ucla.edu>
7867
7868 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
7869 all the test at once. This makes the output easier to read in the
7870 normal case.
7871
7872 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7873 got from <http://bro-ids.org/download.html>. The bug is that
7874 when two actions appeared in succession, the second one was
7875 scanned before the first one was added to the grammar rule
7876 as a midrule action. Bison then output the incorrect warning
7877 "parse.y:905.17-906.36: warning: unused value: $3".
7878 * src/parse-gram.y (BRACED_CODE, action): These are no longer
7879 associated with a value.
7880 (rhs): Don't invoke grammar_current_rule_action_append.
7881 (action): Invoke it here instead.
7882 * src/reader.c (grammar_midrule_action): Now extern.
7883 (grammar_current_rule_action_append): Don't invoke
7884 grammar_midrule_action; that is now the scanner's job.
7885 * src/reader.h (last_string, last_braced_code_loc):
7886 (grammar_midrule_action): New decls.
7887 * src/scan-gram.l (last_string): Now extern, sigh.
7888 (last_braced_code_loc): New extern variable.
7889 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
7890 rule already has an action.
7891 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
7892 * tests/input.at (AT_CHECK_UNUSED_VALUES):
7893 Add some tests to check that the above changes fixed the bug.
7894
78952006-01-27 Paul Eggert <eggert@cs.ucla.edu>
7896
7897 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
7898 All used changed. Check whether the symbol has a destructor,
7899 not whether it is typed.
7900 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
7901 that the values are still reported as unused. All line numbers
7902 adjusted.

7915 Work around a bug in Pike 7.0, and give the Pike folks a
7916 better way to override the usual int widths.
7917 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
7918 user can override the types.
7919 (short): #undef, to work around a bug in Pike 7.0.
7920 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
7921 (union yyalloc.yyss): Use yytype_int16 rather than short.
7922 All uses changed.
7923 (yysigned_char): Remove.
7924 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
7925 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
7926 * tests/regression.at (Web2c Actions): Adjust to above changes.
7927
7928 * src/reader.c (check_and_convert_grammar): New function.
7929 (reader): Close the input file even if something went wrong during
7930 parsing. Minor file descriptor leak reported by twlevo.
7931
7932 * src/assoc.c (assoc_to_string): Use a default: abort (); case
7933 to pacify gcc -Wswitch-default.
7934 * src/scan-gram.l (adjust_location): Use a default: break; case
7935 to pacify gcc -Wswitch-default.
7936 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
7937 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
7938 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
7939 Move these decls to scan-skel.l, since they don't need to be
7940 visible elsewhere.
7941 * src/scan-skel.l: Accept the above decls.
7942 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
7943 is used.

7947 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
7948 since we don't want to insist on a version number at the start
7949 of the changelog every time.
7950 * Makefile.maint: Sync from coreutils a bit better.
7951 (sc_trailing_blank): Renamed from sc_trailing_space.

8018 * src/conflicts.c (resolve_sr_conflict):
8019 Use a default case rather than one for the one remaining enum
8020 value, to catch invalid enum values as well.
8021 * src/lalr.c (set_goto_map, map_goto):
8022 Prefer "assert (FOO);" to "if (!FOO) abort ();".

8045 * src/state.c (transitions_to): Likewise.

8049 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
8050 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
8051 for the benefit of some pre-C99 compilers.
8052
8053 * bootstrap: Undo changes to gnulib files that autoreconf made.
8054
8055 Minor fixups to get 'make maintainer-check' to work.
8056 * configure.ac: Don't use -Wnested-externs, as it's incompatible
8057 with the new verify.h implementation.
8058 * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
8059 * data/glr.c (YYUSE): Depend on __GNUC__ as well.

8065 about the constant value.
8066 * src/reader.c (symbol_typed_p): Add parens to pacify GCC.

8097 (sc_unmarked_diagnostics): Look in all files, not just *.c.
8098 (sc_useless_cpp_parens): New rule.
8099 (news-date-check): Look for version or today's date.
8100 (changelog-check): Don't require version number near head.
8101 (copyright-check): Use current year instead of hardwiring 2005.
8102 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
8103 (announcement): Add --gpg-key-ID.
8104
8105 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
8106 with "file system".
8107
8108 Avoid undefined behavior that addressed just before the start of an
8109 array. Problem reported by twlevo.
8110 * src/reader.c (packgram): Prepend a new sentinel before ritem.
8111 * src/lalr.c (build_relations): Rely on new sentinel.
8112 * src/gram.c (gram_free): Adjust to new sentinel.
8113
81142006-01-12 Joel E. Denny <jdenny@ces.clemson.edu>
8115
8116 * data/glr.c (yyGLRStateSet): Rename yylookaheadStatuses to
8117 yylookaheadNeeds. All uses updated.
8118 (yysplitStack): Rename local yynewLookaheadStatuses to
8119 yynewLookaheadNeeds.
8120 * data/glr-regression.at (Incorrect lookahead during nondeterministic
8121 GLR): In comments, change `lookahead status' to `lookahead need'.
8122
81232006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
8124
8125 * data/glr.c (yysplitStack): A little stylistic rewrite.
8126
81272006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
8128
8129 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
8130
81312006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
8132
8133 * doc/bison.texinfo: Fix some typos.
8134 (GLR Semantic Actions): New subsection discussing special
8135 considerations because GLR semantic actions might be deferred.
8136 (Actions): Mention look-ahead usage of yylval.
8137 (Actions and Locations): Mention look-ahead usage of yylloc.
8138 (Special Features for Use in Actions): Add YYEOF entry and mention it
8139 in the yychar entry.
8140 In the yychar entry, remove mention of the local yychar case (pure
8141 parser) since this is irrelevant information when writing semantic
8142 actions and since it's already discussed in `Table of Symbols' where
8143 yychar is otherwise described as an external variable.
8144 In the yychar entry, don't call it the `current' look-ahead since it
8145 isn't when semantic actions are deferred.
8146 In the yychar and yyclearin entries, add note about deferred semantic
8147 actions.
8148 Add yylloc and yylval entries discussing look-ahead usage.
8149 (Look-Ahead Tokens): When discussing yychar, don't call it the
8150 `current' look-ahead, and do mention yylval and yylloc.
8151 (Error Recovery): Cross-reference `Action Features' when mentioning
8152 yyclearin.
8153 (Table of Symbols): In the yychar entry, don't call it the `current'
8154 look-ahead.
8155 In the yylloc and yylval entries, mention look-ahead usage.
8156
81572006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
8158
8159 * tests/glr-regression.at: Update copyright year to 2006.
8160
81612006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
8162
8163 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
8164 use during nondeterministic operation to track which stacks have
8165 actually needed the current lookahead.
8166 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
8167 Allocate, deallocate, resize, and otherwise shuffle space for
8168 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
8169 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
8170 appropriately during nondeterministic operation.
8171 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
8172 members to store the current lookahead to be used by the deferred
8173 user action.
8174 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
8175 from which the RHS is taken. Set the lookahead members of the new
8176 yySemanticOption according to the lookahead status for stack yyk.
8177 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
8178 yyaddDeferredAction.
8179 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
8180 members of yySemanticOption before invoking yyuserAction, and then set
8181 them back to their current values afterward.
8182 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
8183 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
8184 * tests/glr-regression.at: Remove `.' from the ends of recent test case
8185 titles for consistency.
8186 (Leaked merged semantic value if user action cuts parse): In order to
8187 suppress lint warnings, use arguments in merge function, and assign
8188 char value < 128 in main.
8189 (Incorrect lookahead during deterministic GLR): New test case.
8190 (Incorrect lookahead during nondeterministic GLR): New test case.
8191
81922006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
8193
8194 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
8195 !yyvaluep as signal that no semantic value is available to print.
8196 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
8197 to print a semantic value.
8198
81992006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
8200
8201 * tests/glr-regression.at: For consistency with my newer test cases,
8202 don't thank myself.
8203
82042006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
8205
8206 * data/glr.c (yyresolveValue): When merging semantic options, if at
8207 least one user action succeeds but a later one cuts the parse, then
8208 destroy the semantic value before returning rather than leaking it.
8209 (yyresolveStates): If a user action cuts the parse and thus
8210 yyresolveValue fails, ignore the (unset) semantic value rather than
8211 corrupting the yyGLRState, and empty the semantic options list since
8212 the user actions should have called all necessary destructors.
8213 Simplify code with YYCHK.
8214 * tests/glr-regression.at (Corrupted semantic options if user action
8215 cuts parse): New test case.
8216 (Undesirable destructors if user action cuts parse): New test case.
8217 Before applying any of this patch, this test case never actually failed
8218 for me... but only because the corrupted semantic options usually
8219 masked this bug.
8220 (Leaked merged semantic value if user action cuts parse): New test
8221 case.
8222
82232006-01-05 Akim Demaille <akim@epita.fr>
8224
8225 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/.

8232 * data/yacc.c (YYMODERN_C): Remove. All uses replaced by
8233 b4_c_modern.
8234 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
8235 than rolling our own.
8236
82372006-01-04 Akim Demaille <akim@epita.fr>
8238
8239 Also warn about non-used mid-rule values.

8244 (grammar_rule_check): Use it.
8245 (grammar_midrule_action): Bind a mid-rule LHS to its rule.

8250
82512006-01-04 Akim Demaille <akim@epita.fr>
8252
8253 * src/reader.c (grammar_midrule_action): If $$ is set in a
8254 mid-rule, move the `used' bit to its lhs.
8255 * tests/input.at (Unused values): New.
8256 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
8257
82582006-01-03 Paul Eggert <eggert@cs.ucla.edu>
8259
8260 * doc/bison.texinfo (Bison Options): Say more accurately what
8261 --yacc does.
8262 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
8263 about declarations in the grammar when in Yacc mode, as POSIX does
8264 not require a diagnostic when the grammar uses extensions.
8265
8266 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
8267
8268 Warn about dubious constructions like "%token T T".
8269 Reported by twlevo.
8270 * src/symtab.h (struct symbol.declared): New member.
8271 * src/symtab.c (symbol_new): Initialize it to false.
8272 (symbol_class_set): New arg DECLARING, specifying whether
8273 this is a declaration that we want to warn about, if there
8274 is more than one of them. All uses changed.
8275
8276 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
8277 Allow multiple %union directives, whose contents concatenate.
8278 * src/parse-gram.y (grammar_declaration): Likewise.
8279 Use muscle_code_grow, so that we don't need stype_line any more.
8280 All uses changed.
8281
8282 * src/muscle_tab.c (muscle_grow): Fix comment.
8283
8284 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:
8285 * data/yacc.c, src/getargs.c, src/output.c, tests/cxx-type.at:
8286 Update copyright year to 2006.
8287
82882006-01-03 Akim Demaille <akim@epita.fr>
8289
8290 Have glr.cc pass (some of) the calc.at tests.
8291 * data/glr.cc (b4_parse_param_orig): New.
8292 (b4_parse_param): Improve its definition, and bound it more
8293 clearly in the skeleton.
8294 (b4_epilogue): Append, instead of prepending, in order to keep
8295 #line consistency.
8296 Simplify the generation of auxiliary functions: locations and
8297 purity are mandated.
8298 (b4_global_tokens_and_yystype): Honor it.
8299 * data/location.cc (c++.m4): Don't include it.
8300 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
8301 and AT_SKEL_CC_IF.
8302 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
8303 AT_LALR1_CC_IF.
8304 Be sure to initialize the first position's filename.
8305 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
8306 mandated anyway.
8307 (AT_CHECK_CALC_GLR_CC): New.
8308 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
8309
83102006-01-02 Akim Demaille <akim@epita.fr>
8311
8312 * src/output.c (output_skeleton): Don't hard wire the inclusion of
8313 c.m4.
8314 * data/c++.m4, data/glr.c, data/yacc.c: Include c.m4.

8321 * tests/cxx-type.at: Reformat whitespace with tabs.
8322 (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo
8323 since it's a member. Rename type to isNterm for clarity.
8324
83252005-12-29 Akim <akim@sulaco.local>
8326
8327 Let glr.cc catch up with symbol_value_print.

8330 (yy_symbol_print, yy_symbol_value_print): Declare them.
8331
83322005-12-28 Paul Eggert <eggert@cs.ucla.edu>
8333
8334 * src/location.h (boundary): Note that a line or column equal
8335 to INT_MAX indicates an overflow.
8336 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
8337 (rule_length_overflow, increment_rule_length, add_column_width):
8338 New functions.
8339 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
8340 (<SC_BRACED_CODE>"}"):
8341 Use increment_rule_length rather than incrementing it by hand.
8342 (adjust_location, handle_syncline): Diagnose overflow.
8343 (handle_action_dollar, handle_action_at):
8344 Fix bug with monstrosities like $-2147483648.

8352 GCC warnings.
8353
83542005-12-27 Paul Eggert <eggert@cs.ucla.edu>
8355

8357 Remove unnecessary forward static decls.
8358
83592005-12-27 Akim Demaille <akim@epita.fr>
8360
8361 * src/reader.c (grammar_current_rule_check): Also check that $$
8362 is used.
8363 Take the rule to check as argument, hence rename as...
8364 (grammar_rule_check): this.
8365 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
8366 Rename as...
8367 (grammar_rule_begin, grammar_rule_end): these, for consistency.
8368 (grammar_midrule_action, grammar_symbol_append): Now static.
8369 * tests/torture.at (input): Don't rely on the default action
8370 being always performed.
8371 * tests/calc.at: "Set" $$ even when the action is "cut" with
8372 YYERROR or other.
8373 * tests/actions.at (Exotic Dollars): Instead of using unused
8374 values, check that the warning is issued.
8375
83762005-12-22 Paul Eggert <eggert@cs.ucla.edu>
8377

8402 -pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
8403 * tests/actions.at (Exotic Dollars): Use unused values.
8404 * tests/calc.at: Likewise.

84112005-12-21 Paul Eggert <eggert@cs.ucla.edu>
8412
8413 Undo 2005-12-01 tentative license wording change. The wording is
8414 still being reviewed by the lawyers, and we don't want to wait for
8415 them before publishing a test release. For now, revert to the
8416 previous wording.
8417 * NEWS: Undo 2005-12-01 change.
8418 * data/glr.c: Revert to previous license wording.
8419 * data/glr.cc: Likewise.
8420 * data/lalr1.cc: Likewise.
8421 * data/location.cc: Likewise.
8422 * data/yacc.c: Likewise.
8423
8424 * NEWS: Reword %destructor vs YYABORT etc.
8425 * data/glr.c: Use American spacing, for consistency.
8426 * data/glr.cc: Likewise.
8427 * data/lalr1.cc: Likewise.
8428 * data/yacc.c: Likewise.
8429 * data/yacc.c: Reformat comments slightly.
8430 * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
8431 for consistency. Fix some spelling errors and reword recently-included
8432 text slightly.
8433 * tests/cxx-type.at: Cast results of malloc, for C++.
8434
84352005-12-21 Joel E. Denny <address@hidden>
8436
8437 * tests/cxx-type.at: Construct a tree, count the parents of shared
8438 nodes, and free each node once and only once. Previously, the memory
8439 for semantic values was leaked instead.
8440
84412005-12-21 Joel E. Denny <address@hidden>
8442
8443 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
8444 (yylval, yylloc): If pure, #define to yystackp->yyval and
8445 yystackp->yyloc similar to yychar and yynerrs.
8446 (yyparse): If pure, remove local yylval and yylloc. Add local
8447 yystackp to accommodate pure definitions of yylval and yylloc.
8448 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
8449 yylvalp and yyllocp to &yylval and &yylloc.
8450 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
8451 namespace. Previously, nerrs and char were missing, but lval and lloc
8452 weren't necessary.
8453 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
8454 yylvalp and yyllocp parameters since, if pure, these are now always
8455 accessible through yystackp. If not pure, they are still accessible
8456 globally.
8457 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
8458 `if (YYID (N))' to pacify lint.
8459
84602005-12-21 Akim Demaille <akim@epita.fr>
8461
8462 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
8463 destroy the RHS symbols of a rule.
8464 * data/yacc.c (yylen): Initialize to 0.
8465 Keep its value to the number of items to possibly shift.
8466 In particular, a regular successful parse that ends on YYFINAL by
8467 a (internal) YYACCEPT must not have yylen != 0.
8468 (yyerrorlab, yyreturn): Pop the RHS.
8469 Reorder a bit to emphasize the `shifting' bits of code.
8470 (YYPOPSTACK): Now accept a number of items to pop.
8471 * data/lalr1.cc: Likewise.
8472 * data/glr.c: Formatting changes.
8473 Use goto instead of fall through.
8474 * doc/bison.texinfo (Destructor Decl): Complete.
8475

8480 * djgpp/config.bat: Replace every occurence of the file name
8481 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
8482 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
8483 * djgpp/config.sed: Replace every occurence of the file name
8484 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
8485 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
8486 * djgpp/djunpack.bat: DJGPP specific file.
8487 * djgpp/fnchange.lst: DJGPP specific file.
8488 * djgpp/README.in: Add new information about how to unpack the bison
8489 source on MSDOS and other systems which have 8.3 file name restrictions
8490 using djunpack.bat and fnchange.lst.

8500 * data/glr.c: Reorder typedef declarations for structs to match order
8501 of struct declarations.
8502 Rename yystack everywhere to yystackp except in yyparse where it's not
8503 a pointer.

8505 consistency.
8506 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
8507 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
8508 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
8509 lint.

8512
8513 * tests/sets.at (Accept): Fix typos in regular expression used to
8514 sed out the final state number.

8517 files include <stdio.h> before <config.h>, which messes up
8518 because the latter defines __EXTENSIONS__. Address the problem
8519 by creating two new little files that include <config.h> first,
8520 then include the flex-generated files. Rewrite everyone else
8521 to include <config.h> first, as well.
8522 * lib/timevar.c: Always include "config.h".
8523 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

8559
8560 Cleanups so that Bison-generated parsers have less lint.
8561 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
8562 Prepend /*ARGSUSED*/, for lint's sake.
8563 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
8564 definition if 'lint' is defined.

8566 All uses of /*CONSTCOND*/0 replaced by YYID(0).
8567 * data/yacc.c: Likewise.
8568 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
8569 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
8570 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
8571 is C++ only.
8572 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
8573 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:

8592 to succeed.
8593
85942005-12-01 Paul Eggert <eggert@cs.ucla.edu>
8595
8596 * NEWS: Document the following change.
8597 * data/yacc.c: Say "parser skeleton" rather than "file", since
8598 it's no longer just a file.
8599 * data/glr.c: Grant a special exception for C GLR parsers, that
8600 reads like the already-existing exception for C LALR(1) parsers.
8601 * data/glr.cc: Likewise.
8602 * data/lalr1.cc: Likewise.
8603 * data/location.cc: Likewise.
8604 * data/yacc.c: Reword the "written by" statement to clarify that
8605 it was the parser skeleton, not the entire output file.
8606 * data/glr.c: Written by Paul Hilfinger.
8607 * data/glr.cc: Written by Akim Demaille.
8608 * data/lalr1.cc: Likewise.

8611
8612 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
8613 Fix typos in previous change that broke 'make check'.
8614 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
8615 supported in C.
8616 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
8617 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
8618 We can revert this once things settle down.
8619
8620 * src/conflicts.c (conflicts_print): Don't print file name twice
8621 when %expect fails because there were no conflicts.
8622 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
8623 change.

8648
86492005-11-14 Akim Demaille <akim@epita.fr>
8650
8651 * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
8652 from 1 to N, while values and location start at 0.
8653 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
8654
86552005-11-14 Akim Demaille <akim@epita.fr>
8656

8729
87302005-11-03 Akim Demaille <akim@epita.fr>
8731
8732 In some (weird) cases, the final state number is incorrect.
8733 Reported by Alexandre Duret-Lutz.

8735 final_state.
8736 (save_reductions): Do it here.

8754 New test.
8755
87562005-10-30 Paul Eggert <eggert@cs.ucla.edu>
8757
8758 * bootstrap (cleanup_gnulib): New function. Use it to clean up
8759 gnulib when interrupted. This fixes some race conditions and
8760 works around some portability problems (one noted by Paul
8761 Hilfinger).
8762
87632005-10-22 Akim <akim@epita.fr>
8764
8765 * Makefile.cfg: Adjust to config -> build-aux.

8794 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
8795
87962005-10-13 Akim Demaille <akim@epita.fr>
8797
8798 * src/scan-skel.l: Output the base name parts of the parser and
8799 header file names.
8800 * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
8801 additional checks.

88052005-10-12 Paul Eggert <eggert@cs.ucla.edu>
8806
8807 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
8808 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
8809 Problem reported by John P. Hartmann.
8810 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
8811 already defined it.
8812
88132005-10-12 Akim Demaille <akim@epita.fr>
8814
8815 * src/parse-gram.y (version_check): Exit 63 to please missing

88612005-10-04 Paul Eggert <eggert@cs.ucla.edu>
8862
8863 Undo the parts of the unlocked-I/O change that substituted
8864 putc or puts for printf. This might hurt performance a bit,
8865 but some people prefer the printf style.
8866 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
8867 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

8888 unused-variable warnings.
8889
88902005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

8895
8896 Use unlocked I/O for a minor performance improvement on hosts like
8897 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8898 is to use the gnlib unlocked-io module, and to prefer putc and
8899 puts to printf when either will work (since the latter doesn't
8900 come in an unlocked flavor).
8901 * bootstrap (gnulib_modules): Add unlocked-io.
8902 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
8903 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

8919 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
8920 * src/system.h: Include unlocked-io.h rather than stdio.h.
8921
8922 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
8923 this confuses xgettext.
8924

8926
8927 * bootstrap (gnulib_modules): Add strverscmp.

8969 for posix systems.
8970

8995
8996 * data/location.cc: New, extract from...
8997 * data/lalr1.cc: here.
8998 (location.hh): Include it after the user prologue, in case the
8999 filename type is defined by the user.
9000 Forward declation location and position before the pre-prologue.
9001 (yyresult_): Rename as...
9002 (yyresult): this, it's a local variable, not an attribute.
9003 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
9004
90052005-10-01 Akim Demaille <akim@epita.fr>
9006
9007 * examples/extexi: Restore the #line generation.
9008
90092005-09-30 Akim Demaille <akim@epita.fr>,
9010 Alexandre Duret-Lutz <adl@gnu.org>
9011
9012 Move the token type and YYSTYPE in the parser class.
9013 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
9014 (parser::token): New, from the moved free definition of tokens.
9015 (parser::semantic_value): Now a full definition instead of an
9016 indirection to YYSTYPE.

9025 to simplify the code.
9026
90272005-09-29 Paul Eggert <eggert@cs.ucla.edu>
9028
9029 Port to SunOS 4.1.4, which lacks strtoul and strerror.

9039 (YYERROR_VERBOSE_IF): Remove.
9040 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
9041 parser members, replaced by...
9042 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
9043 local variables.
9044 (yysyntax_error_): Takes the state number as argument.
9045 (yyreduce_print_): Use the argument yyrule, not the former
9046 attribute yyn_.
9047
90482005-09-26 Paul Eggert <eggert@cs.ucla.edu>
9049
9050 * bootstrap (gnulib_modules): Add verify.
9051 * lib/.cvsignore: Add verify.h.

9053 * src/system.h (verify): Remove.
9054 Include verify.h instead.

9056
90572005-09-21 Paul Eggert <eggert@cs.ucla.edu>
9058
9059 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
9060 local variables whose names begin with 'yy'.
9061 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
9062 Trivial changes from Joel E. Denny.
9063
9064 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
9065 it itself.
9066 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
9067 don't use alloca any more.
9068
9069 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
9070 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
9071 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
9072 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
9073 to match yacc.c, to test more hosts.
9074
90752005-09-20 Paul Eggert <eggert@cs.ucla.edu>
9076
9077 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
9078 doesn't affect behavior.
9079 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
9080 Solaris, AIX, MSC.
9081 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
9082 This works a bit better with glibc, if user code has already included
9083 stdlib.h.
9084 * doc/bison.texinfo (Bison Parser): Document that users can't
9085 arbitrarily use malloc and free for other purposes. Document
9086 that <alloca.h> and <malloc.h> might be included.
9087 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
9088 user must declare alloca.

9098
9099 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
9100 (YYSTACK_ALLOC_MAXIMUM): Use it.
9101 (yysyntax_error): New function.
9102 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
9103 multiple syntax errors are reported, and alloca is being used.
9104 Instead, reallocate buffers twice as big each time, so that
9105 we waste at most half the allocated memory. Start with a small
9106 (128-byte) buffer that will suffice in most cases anyway.
9107 Use yysyntax_error to do most of the work.
9108
9109 * doc/bison.texinfo (Error Reporting, Table of Symbols):
9110 yynerrs is the number of errors reported, not the number of
9111 errors encountered.
9112
9113 * tests/glr-regression.at (Duplicated user destructor for lookahead):
9114 Mark it as expected to fail.
9115 Cast result of malloc; problem reported by twlevo@xs4all.nl.
9116 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
9117 Don't start user-code symbols with "yy", to avoid name space problems.
9118
91192005-09-19 Akim Demaille <akim@epita.fr>
9120
9121 Remove the traits, failed experiment.
9122 It never proved useful, and anyway because of the current
9123 definition, it was not possible to have several specialization of
9124 this traits, making it useless.
9125 * data/lalr1.cc (yy:traits): Remove.
9126 Inline its definitions in the parser class.
9127
91282005-09-19 Akim Demaille <akim@epita.fr>
9129
9130 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at

91332005-09-19 Akim Demaille <akim@epita.fr>
9134
9135 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
9136 and yytoken for similarity with the other skeletons.

9149 diagnostic.
9150 * src/output.c (prepare): Likewise.
9151 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
9152 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
9153 is not defined. This is an awful hack, but it's enough for now.
9154 All callers changed.
9155 * tests/glr-regression-at (make_value): Args are const pointers now,
9156 to avoid GCC warning.
9157 (Duplicated user destructor for lookahead): New test. Currently
9158 skipped. It fails on my host but I'm not sure it'll always fail.
9159
91602005-09-16 Akim Demaille <akim@epita.fr>
9161
9162 * src/symtab.h (struct symbol): Declare the printer and destructor
9163 as const, to avoid accidental calls to free.

9165 * src/symtab.c: Adjust.
9166
91672005-09-16 Akim Demaille <akim@epita.fr>
9168
9169 * data/c.m4 (b4_token_enums): New.
9170 (b4_token_defines): Rename as...
9171 (b4_token_enums_defines): this.
9172 (b4_token_defines): New, output only the #defines.
9173 * data/yacc.c, data/glr.c: Adjust.
9174 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
9175 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
9176 as default values.
9177
91782005-09-16 Akim Demaille <akim@epita.fr>
9179
9180 * data/lalr1.cc (yylex_): Remove, inline its code.
9181 (yyreport_syntax_error_): Remove, replaced by...
9182 (yysyntax_error_): this which returns a string and leaves to the
9183 caller the call to the users' error function.
9184 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
9185 Move from members of the parser object...
9186 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
9187 to local variables of the parse function.
9188
91892005-09-16 Akim Demaille <akim@epita.fr>
9190
9191 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
9192 since it's in Bison's name space.
9193
91942005-09-15 Paul Eggert <eggert@cs.ucla.edu>
9195
9196 * data/glr.c (yyresolveValue): Add default case to pacify
9197 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
9198
9199 * NEWS: Document when yyparse started to return 2.
9200 * doc/bison.texinfo (Parser Function): Document when yyparse
9201 returns 2.
9202
9203 * data/lalr1.cc: Revert part of previous change, as it's incompatible.

92082005-09-14 Paul Eggert <eggert@cs.ucla.edu>
9209
9210 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
9211 do anything if $@ exists. This reverts part of the 2005-07-07
9212 patch.
9213
92142005-09-11 Paul Eggert <eggert@cs.ucla.edu>
9215
9216 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
9217 contains obsolete information and isn't worth distributing as a
9218 separate file anyway.
9219 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
9220 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
9221 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
9222 (yyparse): Abort if user code uses longjmp to throw an unexpected
9223 value.
9224
92252005-09-09 Paul Eggert <eggert@cs.ucla.edu>
9226
9227 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
9228 Suggested by twlevo@xs4all.nl.
9229
9230 * data/glr.c (YYCHK1): Do not assume YYE is in range.
9231 This avoids a diagnostic from gcc -Wswitch-enum.
9232 Problem reported by twlevo@xs4all.nl.
9233
9234 * doc/bison.texinfo: Don't use "filename", as per GNU coding
9235 standards. Use "file name" or "file" or "name", depending on
9236 the context.
9237 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
9238 not to hack/foo.tab.c.
9239 (Calc++ Top Level): 2nd arg of main is not const.
9240 * data/glr.c: b4_filename -> b4_file_name.
9241 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
9242 All uses changed.
9243 (class position): filename -> file_name. All uses changed.
9244 * data/yacc.c: b4_filename -> b4_file_name.
9245 * lib/bitset.h: filename -> file_name in local vars.
9246 * lib/bitset_stats.c: Likewise.
9247 * src/files.c: Likewise.
9248 * src/scan-skel.l ("@output ".*\n): Likewise.
9249 * src/files.c (file_name_split): Renamed from filename_split.
9250 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
9251
92522005-09-08 Paul Eggert <eggert@cs.ucla.edu>
9253
9254 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
9255 to accommodate latest gnulib.
9256
9257 * tests/glr-regression.at (Duplicate representation of merged trees):
9258 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
9259
9260 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
9261 needed.
9262
92632005-08-26 Paul Eggert <eggert@cs.ucla.edu>
9264
9265 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
9266 All uses changed. Invoke user destructor after an error during a
9267 split parse (trivial change from Joel E. Denny).
9268
9269 * tests/glr-regression.at
9270 (User destructor after an error during a split parse): New test case.
9271 Problem reported by Joel E. Denny in:
9272 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
9273
92742005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9275
9276 * README-cvs: Give URLs for recommended tools.
9277 Mention Gzip version problem, and bootstrapping issues.
9278 Remove troubleshooting section, as it's somewhat obsolete.
9279
9280 * bootstrap (no_cache): New var, to accommodate different wget
9281 variants. Use it instead of '-C off'. Problem reported by
9282 twlevo@xs4all.nl.
9283
9284 * data/glr.c (yydestroyStackItem): New function.
9285 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of

9287
92882005-08-25 Akim Demaille <akim@epita.fr>
9289
9290 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
9291
92922005-08-24 Paul Eggert <eggert@cs.ucla.edu>
9293

9299 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
9300
93012005-08-21 Paul Eggert <eggert@cs.ucla.edu>
9302
9303 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
9304 Add strnlen.c.
9305 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
9306 lib-prefix.m4, po.m4.
9307
9308 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
9309 in yydestruct diagnostic, since it might not be an error.
9310 Problem reported by Joel Denny near end of
9311 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9312 * data/lalr1.cc (yyerturn): Likewise.
9313 * data/yacc.c (yyreturn): Likewise.
9314 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
9315
9316 * src/files.c: Remove obsolete FIXME comment.
9317
9318 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
9319 with the other templates, and to fix bogus run-on messages such
9320 as the one reported at the end of
9321 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9322 All callers changed to avoid the newline.
9323 (yyprocessOneStack): Output two lines rather than one, to accommodate
9324 the above change. This changes the debug output format slightly.
9325
9326 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
9327 reported by Joel E. Denny in
9328 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
9329 (trivial change).
9330 * tests/glr-regression.at (Duplicate representation of merged trees):
9331 New test, from Joel E. Denny in:
9332 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
9333 * THANKS: Add Joel E. Denny.
9334
9335 * configure.ac (AC_INIT): Bump to 2.0c.
9336
93372005-07-24 Paul Eggert <eggert@cs.ucla.edu>
9338
9339 * NEWS: Version 2.0b.
9340
9341 * Makefile.am (SUBDIRS): Put examples before tests, so that
9342 "make check" doesn't finish with "All 1 tests passed".
9343
9344 * tests/regression.at (Token definitions): Don't rely on
9345 AT_PARSER_CHECK for data that contains backslashes. It currently
9346 uses 'echo', and 'echo' isn't portable if its argument contains
9347 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9348 that the byte '\0xff' is not printable in the C locale; it is,
9349 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9350 not printable, so use '\0x81' to test.
9351
9352 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
9353 version of GCC, since the macro is used with non-GCC compilers.
9354
9355 Fix core dump reported by Pablo De Napoli in
9356 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
9357 * tests/regression.at (Invalid inputs with {}): New test.
9358 * src/parse-gram.y (token_name): Translate type before using
9359 it as an index.
9360
9361 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
9362 the user's name space. All uses changed to __attribute__
9363 ((__unused__)).
9364 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
9365 Add __attribute__ ((__noreturn__)).
9366
9367 * etc/clcommit: Remove. We weren't using it, and it failed
9368 "make maintainer-distcheck".
9369 * Makefile.maint: Merge from coreutils.
9370 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
9371 (syntax-check-rules): Change list of rules as described below.

9385 (dd_c): New macro.
9386 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
9387 (my-distcheck): Use more-modern GCC flags.
9388 (signatures, %.asc): Remove.
9389 (rel-files, announcement): Remove signatures.
9390 Restore old updating code, even though we don't use it, so
9391 that we're the same as coreutils.
9392 (alpha, beta, major): Depend on news-date-check.
9393 Make the upload commands.
9394
9395 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

9402 * tests/sets.at: Likewise.
9403
9404 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9405 we comment out the Autoconf version number.
9406 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9407 it's error-prone and "make maintainer-distcheck" rejects it.
9408
9409 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9410 Indent calls to "error" to pacify "make maintainer-distcheck",
9411 when the calls are not intended to be translated.
9412 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9413
9414 * src/Makefile.am (DEFS): Use +=, to pacify
9415 "make maintainer-distcheck".
9416 (bison_SOURCES): Add scan-skel.h.
9417 (sc_tight_scope): New rule, from coreutils.
9418

9426 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9427 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9428 void, to avoid warning when NLS is disabled.
9429 * src/output.c: Include scan-skel.h.
9430 (scan_skel): Remove decl, since scan-skel.h does this.
9431 (output_skeleton):
9432 Indent calls to "error" to pacify "make maintainer-distcheck".
9433 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9434 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9435 "make maintainer-distcheck".
9436 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):

9442 Indent calls to "error" to pacify "make maintainer-distcheck".

9444 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9445 not @VAR@.
9446
9447 * tests/torture.at: Revamp to avoid misuse of atoi that
9448 "make maintainer-distcheck" complained about.
9449
9450 * examples/extexi (message): Don't print a message more than once,
9451 and omit line-number decoration that makes Emacs compile think
9452 that informative messages are worth worrying about.
9453
94542005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9455
9456 * configure.ac: Update version number.
9457
9458 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9459 accidentally.
9460 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9461 autogenerated by the maintainer.
9462 * examples/calc++/.cvsignore: Add *.yy.
9463
9464 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9465 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9466 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9467
9468 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9469
9470 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9471 from maintainer-distcheck about casting the argument of 'free'.
9472
9473 * NEWS: Mention recent yytname changes.
9474 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9475
9476 * bootstrap: For translations that have not yet been upgraded to
9477 the new runtime-po domain, prime the pump by extracting the
9478 relevant strings from the obsolete translations. This code can be
9479 removed once the bison-runtime domain has been translated by each
9480 team.
9481
9482 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9483 now that token names are already quoted.
9484
9485 Fix problem reported by Anthony Heading.
9486 * data/glr.c (YYTOKEN_TABLE): New macro.
9487 (yytname): Define if YYTOKEN_TABLE.
9488 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
9489 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
9490 (YYERROR_VERBOSE): Define the same way the other skeletons do.
9491 * src/output.c (prepare_symbols): Output token_table_flag.
9492
94932005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9494
9495 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9496 again if the first call fails.
9497
9498 * data/glr.c (yytnamerr): New function.
9499 (yyreportSyntaxError): Use it to dequote most string literals.
9500 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9501 with other skeletons. All uses changed.
9502 (yytnameerr_): New function.
9503 (yyreport_syntax_error): Use it to dequote most string literals.
9504 * data/yacc.c (yytnamerr): New function.
9505 (yyerrlab): Use it to decode most string literals.
9506 * doc/bison.texinfo (Decl Summary, Calling Convention):
9507 Clarify quoting convention of yytname.
9508 * src/output.c (prepare_symbols): Quote all names. This undoes
9509 the 2005-04-17 change, which is now accomplished (mostly) via
9510 changes in the parsers as described above.
9511 * tests/regression.at (Token definitions, Web2c Actions):
9512 Undo most 2005-04-17 change here, too.
9513
95142005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9515
9516 Fix more problems reported by twlevo@xs4all.nl.
9517 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9518 remove trailing spaces. This loses the exit status of ./types,
9519 and isn't needed since ./types shouldn't be emitting trailing
9520 spaces.
9521 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9522 as the stack isn't valid in that case.
9523
9524 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9525 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9526 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9527 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9528 is used.
9529 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
9530 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9531 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9532 Likewise.
9533
9534 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9535 overly-picky compilers that reject 'char *foo = "bar";'.
9536
9537 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9538 to FILE * parameter, not to stderr. This fixes a typo introduced
9539 in the 2005-07-12 change.
9540
9541 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
9542 warnings from GCC 4.
9543
9544 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
9545 (yyglrShiftDefer, yysplitStack):
9546 Remove unused parameters b4_pure_formals. All uses changed.
9547 (yyglrShift): Remove unused parameters b4_user_formals.
9548 All uses changed.
9549 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
9550
95512005-07-18 Paul Eggert <eggert@cs.ucla.edu>
9552
9553 Destructor cleanups and regularization among the three skeletons.
9554 * NEWS: Document the behavior changes.
9555 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9556 stack before failing, as the cleanup code will do it for us now.
9557 * data/lalr1.cc (yyerrlab): Likewise.
9558 * data/glr.c (yyparse): Pop everything off the stack before
9559 freeing it, so that destructors get called properly.
9560 * data/lalr1.cc (yyreturn): Likewise.
9561 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9562 This is more consistent.
9563 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9564 why destructors might be called. 1.875 -> 2.1.
9565 (Destructor Decl, Decl Summary, Table of Symbols):
9566 Some English-language cleanups for %destructor.
9567 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9568 Add output line for destructor of start symbol.
9569 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
9570 because of that same extra output line.
9571
9572 * NEWS: Document minor wording changes in diagnostics of
9573 Bison-generated parsers.
9574 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
9575 Remove unused formals. All uses changed.
9576 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9577 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9578 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9579 Rename yyoverflowab to yyexhaustedlab.
9580 When memory exhaustion occurs during syntax-error reporting,
9581 report it separately rather than in a single diagnostic; this
9582 eases translation.
9583 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
9584 (Memory Exhausted): Renamed from Parser Stack Overflow.
9585 Revamp wording slightly to prefer "memory exhaustion".
9586 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
9587
9588 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
9589
9590 Add i18n support to the GLR skeleton. Partially fix the C++
9591 skeleton; a C++ expert needs to finish this. Remove debugging
9592 msgids; there's little point to having them translated, since they
9593 can be understood only by someone who can read the
9594 (English-language) source code.
9595
9596 Generate runtime-po/bison-runtime.pot automatically, so that we
9597 don't have to worry about garbage getting in that file. We'll
9598 make sure after the next official release that old msgids don't
9599 get lost. See
9600 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
9601
9602 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
9603 Now auto-generated.
9604 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9605 Fix typos in explanations of the runtime file.
9606 * bootstrap: Change gettext keyword from YYI18N to YY_.
9607 Use standard Makefile.in.in in runtime-po, since we'll arrange
9608 for backward-compatible bison-runtime.po files in a different way.
9609 * data/glr.c (YY_): New macro, from yacc.c.
9610 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9611 Translate messages intended for users.
9612 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9613 the wording in the other skeletons. We don't know that the memory
9614 is virtual.
9615 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9616 Use same method that yacc.c uses.
9617 Don't translate debugging messages.
9618 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9619 it doesn't work (yet), and requires C++ expertise to fix.
9620 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9621 Move defn to a more logical place, to be consistent with other
9622 skeletons.
9623 Don't translate debugging messages.
9624 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9625 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9626 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9627 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
9628
9629 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
9630 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
9631 void, not int.
9632 * tests/glr-regression.at (Badly Collapsed GLR States):
9633 Likewise.
9634 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9635 yylex should return 0 at EOF rather than aborting.
9636
9637 Improve tests for stack overflow in GLR parser.
9638 Problem reported by twlevo@xs4all.nl.
9639 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
9640 All uses removed.
9641 (yyStackOverflow): Just longjmp, but with value 2 so that caller
9642 can handle the problem.
9643 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
9644 (yyparse): New local variable yyresult to record the result.
9645 Use result of setjmp to set it, rather than storing itinto
9646 struct.
9647 (yyDone): Remove label.
9648 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
9649 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
9650 if YYABORT is used).
9651 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
9652 yyparse status; put status > 1 into diagnostic.
9653 Check that status==2 works.
9654 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
9655 Use exit status 3 for failure to open (which shouldn't happen).
9656
96572005-07-17 Paul Eggert <eggert@cs.ucla.edu>
9658
9659 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
9660 1 on syntax error; just let yyparse do its thing.
9661 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
9662 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
9663 (Exploding the Stack Size with Alloca):
9664 (Exploding the Stack Size with Malloc):
9665 Expect exit status 2, not 1, since the parser is supposed to blow
9666 its stack. Problem reported by twlevo@xs4all.nl.
9667
9668 * data/glr.c (yyparse): Don't assume that the initial calls
9669 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
9670 Print a stack-overflow message and fail instead.
9671 Initialize the line-number information before creating the stack,
9672 so that the stack-overflow message can report line zero safely.
9673
96742005-07-14 Paul Eggert <eggert@cs.ucla.edu>
9675
9676 Fix problems reported by twlevo@xs4all.nl.
9677 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
9678 (yyuserMerge): Provide a default case if b4_mergers is empty.
9679 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
9680 * tests/glr-regression.at
9681 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9682 Add casts to pacify C++ compilers.
9683 * tests/glr-regression.at (Improper merging of GLR delayed action
9684 sets): Declare yylex before using it.
9685 * tests/Makefile.am (maintainer-check-g++): Fix a stray
9686 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
9687 test for valgrind; valgrind is independent of g++.
9688 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
9689 for compatibility with POSIX 1003.1-2001 (if running coreutils).
9690 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
9691 Use a destructor, so that we can expand the stack. Change
9692 YYSTYPE to char * so that we can free it. Cast result of malloc.
9693
96942005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9695
9696 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
9697 a valgrind failure. Problem reported by twlevo@xs4all.nl.
9698
96992005-07-13 Paul Eggert <eggert@cs.ucla.edu>
9700
9701 * PACKAGING: New file, suggested by Bruno Haible and taken from
9702 similar wording in gettext's PACKAGING file.
9703 * NEWS: Mention PACKAGING.
9704 * Makefile.am (EXTRA_DIST): Add PACKAGING.
9705
97062005-07-12 Paul Eggert <eggert@cs.ucla.edu>
9707
9708 * NEWS: Document recent i18n improvements.
9709 * bootstrap: Get runtime translations into runtime-po.
9710 Create runtime-po files automatically, if possible.
9711 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
9712 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
9713 does not infringe on the user's name space.
9714 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
9715 * doc/bison.texinfo (Internationalization): Revamp the English
9716 and Texinfo syntax a bit, to try to make it clearer.
9717 (Bison Options, Option Cross Key): Mention --print-localedir.
9718 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
9719 YYENABLE_NLS. Quote a bit more.
9720 * runtime-po/.cvsignore: New file.
9721 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
9722 * runtime-po/Rules-quot: Remove; now created by bootstrap.
9723 * runtime-po/quot.sed: Likewise.
9724 * runtime-po/boldquot.sed: Likewise.
9725 * runtime-po/en@quot.header: Likewise.
9726 * runtime-po/en@boldquot.header: Likewise.
9727 * runtime-po/insert-header.sin: Likewise.
9728 * runtime-po/remove-potcdate.sin: Likewise.
9729 * runtime-po/Makevars: Likewise.
9730 * runtime-po/LINGUAS: Likewise.
9731 * runtime-po/de.po: Likewise; we will rely on the translation project
9732 to maintain this, so "bootstrap" should get it.
9733 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
9734 its value.
9735 * src/main.c (main): Bind the bison-runtime domain, too.
9736
97372005-07-12 Bruno Haible <bruno@clisp.org>
9738
9739 * data/yacc.c: Include <libintl.h> when NLS is enabled.
9740 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
9741 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
9742 * runtime-po: New directory.
9743 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
9744 $(DOMAIN).pot-update rule, so that old messages are never dropped.
9745 * runtime-po/Rules-quot: New file, copied from po/.
9746 * runtime-po/quot.sed: Likewise.
9747 * runtime-po/boldquot.sed: Likewise.

9771 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
9772 for consistency with the rest of the code.
9773 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
9774 Add separators.
9775
97762005-07-12 Akim Demaille <akim@epita.fr>
9777
9778 * src/parse-gram.y: Use %printer instead of YYPRINT.
9779
97802005-07-12 Akim Demaille <akim@epita.fr>
9781
9782 * src/symtab.h, src/symtab.c (symbol_print): New.
9783 * src/symlist.h, src/symlist.c (symbol_list_print): New.
9784 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
9785
97862005-07-12 Akim Demaille <akim@epita.fr>
9787
9788 * data/glr.c (b4_syncline): Fix (swap) the definitions of
9789 b4_at_dollar and b4_dollar_dollar.
9790
97912005-07-11 Paul Eggert <eggert@cs.ucla.edu>
9792
9793 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
9794 and Pennello's paper.
9795
97962005-07-09 Paul Eggert <eggert@cs.ucla.edu>
9797
9798 * data/yacc.c (yyparse): Undo previous patch. Instead,
9799 set yylsp[0] and yyvsp[0] only if the initial action
9800 sets yylloc and yylval, respectively.
9801
9802 * data/yacc.c (yyparse): In the initial action, set
9803 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
9804 This avoids the use of undefined variables if the initial
9805 action does not set yylloc and/or yylval.
9806
98072005-07-07 Paul Eggert <eggert@cs.ucla.edu>
9808
9809 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
9810 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
9811 Remove from CVS. These files are automatically generated.
9812 * examples/extexi: Clarify that this file is now part of Bison,
9813 not GNU M4, and that it works with any POSIX-compatible Awk.
9814 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
9815 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
9816 so that we also get calc++-parser.yy. Geneate it.
9817 Use $(AWK), not gawk, since any conforming Awk will do.
9818 Put comment before action, since older 'make' can't handle comment
9819 in action.
9820 $(BUILT_SOURCES): List all built sources, not just some of them.
9821 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
9822 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
9823 $($(calc_sources_generated)): Remove unnecessary test for existence
9824 of target. (This had a shell syntax error anyway; a stray "x".)
9825 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
9826 calc++-parser.yy.
9827 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
9828
9829 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
9830 implied by the other modules.
9831
98322005-07-06 Akim Demaille <akim@epita.fr>
9833
9834 Bind examples/calc++ to the package.
9835 * examples/calc++/Makefile: Remove, replaced by...
9836 * examples/calc++/Makefile.am: ... this new file.
9837 * examples/calc++/test: Remove input.
9838 * examples/calc++/compile: Remove.
9839 * examples/Makefile.am: New.
9840 * configure.ac, Makefile.am: Adjust.
9841 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
9842
98432005-07-05 Paul Eggert <eggert@cs.ucla.edu>
9844
9845 * data/glr.c (yyFail): Drastically simplify; since the format argument
9846 never had any % directives, we can simply pass it to yyerror.
9847 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
9848 be modified later, as that is the usual style in glr.c.
9849 Problems reported by Paul Hilfinger.
9850
9851 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
9852 and size overflow errors.
9853 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
9854 in case the user prolog sets feature-test macros like _GNU_SOURCE.
9855 (YYSIZEMAX): New macro.
9856 (yystpcpy): New function, taken from yacc.c.
9857 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9858 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9859 so that we don't have to maintain their signatures.
9860 (yyFail): Check for buffer overflow, by using vsnprintf rather
9861 than vsprintf. Allocate a bigger buffer if possible.
9862 Report an error if buffer allocation fails.
9863 (yyStackOverflow): New function.
9864 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9865 the initialization was successful. It might fail if storage was
9866 exhausted.
9867 (yyexpandGLRStack): Add more checks for storage allocation failure.
9868 Use yyStackOverflow to report failures.
9869 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
9870 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
9871 Don't assume stack number fits in int.
9872 (yysplitStack): Check for storage allocation failure.
9873 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
9874 can print diagnostics on storage allocation failure. All callers
9875 changed.
9876 (yyresolveValue): Use yybool for boolean.
9877 (yyreportSyntaxError): Check for size-calculation overflow.
9878 This code is taken from yacc.c.
9879 (yyparse): Check for storage allocation errors when allocating
9880 the initial stack.
9881
98822005-07-05 Akim Demaille <akim@epita.fr>
9883
9884 Extract calc++ from the documentation.
9885 * doc/bison.texinfo (Calc++): Add the extraction marks.
9886 * examples/extexi: New, from the aborted GNU Programming 2E.
9887 Separate the different paragraph of a file with empty lines.
9888 * examples/Makefile: Use it to extract the whole calc++ example.
9889
98902005-06-24 Akim Demaille <akim@epita.fr>
9891
9892 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
9893 class typedefs.
9894
98952005-06-22 Akim Demaille <akim@epita.fr>
9896
9897 * doc/bison.texinfo (C++ Language Interface): First stab.
9898 (C++ Parsers): Remove.
9899
99002005-06-22 Akim Demaille <akim@epita.fr>
9901
9902 * data/lalr1.cc (yylex_): Honor %lex-param.
9903
99042005-06-22 Akim Demaille <akim@epita.fr>
9905
9906 Start a set of simple examples.
9907 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
9908 * examples/calc++/calc++-driver.hh,
9909 * examples/calc++/calc++-parser.yy,
9910 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
9911 * examples/calc++/compile, examples/calc++/test: New.
9912
99132005-06-09 Paul Eggert <eggert@cs.ucla.edu>
9914
9915 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
9916 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
9917 which stems from the 2005-05-27 patch.
9918
99192005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9920
9921 * data/glr.c: Modify treatment of unused parameters to permit use
9922 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
9923
99242005-05-30 Paul Eggert <eggert@cs.ucla.edu>
9925
9926 Fix infringement on user name space reported by Janos Zoltan Szabo.
9927 * data/yacc.c (yyparse): strlen -> yystrlen.
9928
99292005-05-30 Akim Demaille <akim@epita.fr>
9930
9931 * data/lalr1.cc (_): New.
9932 Translate the various messages.
9933
99342005-05-27 Paul Eggert <eggert@cs.ucla.edu>
9935
9936 Fix infringement on user name space reported by Bruno Haible.
9937 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9938 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9939 the user's name space.
9940 (alloca): Include <stdlib.h> to get it, if it's not built in.
9941 (YYMALLOC, YYFREE): Define only if needed.
9942 (malloc, free): Declare, but only if needed, as this infringes on
9943 the user name space.
9944
99452005-05-25 Paul Eggert <eggert@cs.ucla.edu>
9946
9947 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
9948 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
9949 with %d format.
9950 * lib/ebitset.c (min, max): Undef before defining.
9951 * lib/vbitset.c (min, max): Likewise.
9952 * lib/subpipe.c (create_subpipe): Save local variables in case
9953 vfork clobbers them.
9954
99552005-05-24 Bruno Haible <bruno@clisp.org>
9956
9957 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
9958 error message syntax used by gcc-4.0.
9959
99602005-05-23 Paul Eggert <eggert@cs.ucla.edu>
9961
9962 * README: Mention m4 1.4.3. Remove obsolete advice about
9963 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
9964
9965 * bootstrap: Remove workaround for problem I encountered with
9966 gettext 0.14.1; it seems to be fixed now.
9967
99682005-05-22 Paul Eggert <eggert@cs.ucla.edu>
9969
9970 * NEWS: Version 2.0a.
9971
9972 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
9973 the previous change.
9974
9975 Various maintainer cleanups.
9976 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9977 conftest*, for benefit of CVS commands run at the same time as
9978 "configure". Add build-aux, since "bootstrap" now creates it and
9979 its subfiles.
9980 * Makefile.cfg (move_if_change): Remove.
9981 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9982 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
9983 (po_repo, do-po-update, po-update, wget_files, get-targets):
9984 (config.guess-url_prefix, config.sub-url_prefix):
9985 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
9986 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
9987 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
9988 Remove.
9989 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
9990 this is now the recommended name.
9991 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
9992 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9993 ylwrap. These files now go into build-aux.
9994 * config/move-if-change: Remove.
9995 * config/prev-version.txt: Bump from 1.75 to 2.0.
9996
9997 * bootstrap: Add stdio-safer, unistd-safer modules.
9998 Remove m4/glibc2.m4 (introduced by latest gnulib, but
9999 we don't need it).
10000 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
10001 fopen-safer.c, stdio-safer.h, unistd-safer.h.
10002 * lib/subpipe.c: Include "unistd-safer.h".
10003 (create_subpipe): Make sure all the newly-created
10004 file descriptors are > 2, so that diagnostics don't
10005 get sent down them (which might cause Bison to hang, in theory).
10006 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
10007 * src/files.c (xfopen): Use fopen_safer, not fopen.
10008
10009 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
10010 yesterday's yacc.c fix.
10011
100122005-05-21 Paul Eggert <eggert@cs.ucla.edu>
10013
10014 * data/glr.c, data/lalr1.cc: Update copyright date.
10015
10016 Fix a destructor bug reported by Wolfgang Spraul in
10017 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
10018 * data/yacc.c (yyabortlab): Don't call destructor, and
10019 don't set yychar to EMPTY.
10020 (yyoverflowlab): Don't call destructor.
10021 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
10022 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
10023 since we no longer output the message "discarding lookahead token
10024 end of input ()".
10025
100262005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10027
10028 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
10029 fix a small glitch in debugging output.
10030 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
10031 after YY_SYMBOL_PRINT where needed.
10032
10033 (struct yyGLRState): Add some comments.
10034 (struct yySemanticOption): Add some comments.
10035 (union yyGLRStackItem): Add comment.
10036
10037 (yymergeOptionSets): Correct this to properly perform the union,
10038 avoiding infinite reported by Michael Rosien.
10039 Update comment.
10040
10041 * tests/glr-regression.at: Add test for GLR merging error reported
10042 by M. Rosien.
10043

10081
100822005-05-11 Paul Eggert <eggert@cs.ucla.edu>
10083
10084 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
10085 Problem reported by Ralf Menzel.
10086
100872005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10088
10089 * tests/actions.at: Test that stack overflow invokes destructors.
10090 From Marcus Holland-Moritz.
10091 * data/yacc.c (yyerrlab): Move the code that destroys the stack
10092 from here....
10093 (yyreturn): to here. That way, destructors are called properly
10094 even if the stack overflows, or the user calls YYACCEPT or
10095 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
10096 (yyoverflowlab): Destroy the lookahead.
10097
100982005-04-24 Paul Eggert <eggert@cs.ucla.edu>
10099
10100 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
10101
101022005-04-17 Paul Eggert <eggert@cs.ucla.edu>
10103
10104 * NEWS: Bison-generated C parsers no longer quote literal strings
10105 associated with tokens.
10106 * src/output.c (prepare_symbols): Don't escape strings,
10107 since users don't want to see C escapes.
10108 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
10109 in diagnostics.
10110 * tests/input.at (Torturing the Scanner): Likewise.
10111 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
10112
101132005-04-16 Paul Eggert <eggert@cs.ucla.edu>
10114
10115 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
10116 the data size is known to be too small and we can't increase it.
10117 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
10118
101192005-04-15 Paul Eggert <eggert@cs.ucla.edu>
10120
10121 * src/parse-gram.y: Include quotearg.h.
10122 (string_as_id): Quote $1 before using it as a key, since the
10123 lexer no longer quotes it for us.
10124 (string_content): Don't strip quotes, since lexer no longer
10125 quotes it for us.
10126 * src/scan-gram.l: Include quotearg.h.
10127 ("\""): Omit quote.
10128 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
10129 a key, since the rest of the lexer doesn't quote it.
10130 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
10131 * tests/regression.at (Token definitions): Check for backslashes
10132 in token strings.
10133
10134 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
10135 (YYSIZE_T): Define to unsigned long int when using an older compiler.
10136 (yyparse): Revamp code to generate long syntax error message, to
10137 make it easier to translate, and to avoid problems with arithmetic
10138 overflow. Change "virtual memory" to "memory" in diagnostic, since
10139 we don't know whether the memory is virtual.
10140
101412005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10142
10143 * NEWS: Bison-generated C parsers now use the _ macro to
10144 translate strings.
10145 * data/yacc.c (_) [!defined _]: New macro.
10146 All English strings wrapped inside this macro.
10147 * doc/bison.texinfo (Bison Parser): Document _.
10148 * po/POTFILES.in: Include src/parse-gram.c, since it now
10149 includes translateable strings that parse-gram.y doesn't.
10150
101512005-04-12 Paul Eggert <eggert@cs.ucla.edu>
10152
10153 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
10154 reverting the 2004-10-11 change to this function.
10155 (symbol_check_alias_consistency): Don't call symbol_type_set
10156 if the type name is already correct.
10157 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
10158
101592005-03-25 Paul Eggert <eggert@cs.ucla.edu>
10160
10161 * tests/regression.at (Token definitions): Don't use a token named
10162 c, as that generates a "#define c ..." that runs afoul of buggy
10163 stdlib.h that uses the identifier c as a member of struct
10164 drand48_data. Problem reported by Horst Wente.
10165
101662005-03-21 Paul Eggert <eggert@cs.ucla.edu>
10167
10168 * bootstrap: Change translation URL from
10169 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
10170 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
10171 redirection glitches. Problem reported by twlevo@xs4all.nl.
10172
101732005-03-20 Paul Eggert <eggert@cs.ucla.edu>
10174
10175 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
10176 after operands; POSIX says this isn't portable for the c99 command.
10177
101782005-03-18 Paul Eggert <eggert@cs.ucla.edu>
10179
10180 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
10181 immediately if a data overrun has occurred; this may help us track
10182 down what may be a spurious failure on MacOS.
10183
101842005-03-17 Paul Eggert <eggert@cs.ucla.edu>
10185
10186 Respond to problems reported by twlevo@xs4all.nl.
10187
10188 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
10189
10190 * src/vcg.h: Comment fix.
10191 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
10192 (G_CMAX): Change to -1 instead of INT_MAX.
10193
10194 * data/yacc.c (yyparse): Omit spaces before #line.
10195
101962005-03-15 Paul Eggert <eggert@cs.ucla.edu>
10197
10198 * src/tables.c (state_number_to_vector_number): Put it inside an
10199 "#if 0", since it's not currently used. Problem reported by
10200 Roland McGrath.
10201
102022005-03-06 Paul Eggert <eggert@cs.ucla.edu>
10203
10204 * src/output.c (escaped_output): Renamed from
10205 escaped_file_name_output, since we now use it for symbol tags as
10206 well. All uses changed.
10207 (symbol_destructors_output, symbol_printers_output):
10208 Escape symbol tags too.
10209 Problem reported by Matyas Forstner in
10210 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
10211
10212 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
10213 not needed.
10214 * src/output.c (user_actions_output, token_definitions_output,
10215 symbol_destructors_output, symbol_printers_output): Likewise.
10216 * src/reader.c (prologue_augment): Likewise.
10217 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
10218

102222005-02-28 Paul Eggert <eggert@cs.ucla.edu>
10223
10224 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
10225 example, reported by Derek M Jones. Also, make the example even
10226 more outrageous, to better illustrate how bad the problem is.
10227
102282005-02-24 Paul Eggert <eggert@cs.ucla.edu>
10229
10230 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
10231 putsym. Typo reported by Sebastian Piping.
10232
102332005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10234
10235 * doc/bison.texinfo (Language and Grammar): some -> same
10236 (Epilogue): int he -> in the
10237 Typos reported by Sebastian Piping via Justin Pence.
10238
102392005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10240
10241 * tests/glr-regression.at (Improper handling of embedded actions
10242 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
10243 embedded actions and $-N in GLR parsers", work around an Autoconf bug
10244 with dollar signs in test names.
10245 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
10246 for a similar reason.
10247
102482005-01-28 Paul Eggert <eggert@cs.ucla.edu>
10249
10250 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
10251 wants to redefine G_VIEW.
10252
102532005-01-27 Paul Eggert <eggert@cs.ucla.edu>
10254

10260 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
10261 Problem reported by twlevo@xs4all.nl.
10262
10263 * doc/bison.texinfo: Change @dircategory from "GNU programming
10264 tools" to "Software development". Requested by Richard Stallman
10265 via Karl Berry.
10266
102672005-01-23 Paul Eggert <eggert@cs.ucla.edu>
10268
10269 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
10270 Problem reported by twlevo@xs4all.nl.
10271
102722005-01-21 Paul Eggert <eggert@cs.ucla.edu>
10273
10274 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
10275 keyword; it's not needed with modern compilers, and it doesn't
10276 affect correctness with older compilers. Suggested by
10277 twlevo@xs4all.nl.
10278
102792005-01-17 Paul Eggert <eggert@cs.ucla.edu>
10280
10281 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
10282 gcc -Wswitch-default.

10284 * data/yacc.c (yyparse): Likewise.
10285
102862005-01-12 Paul Eggert <eggert@cs.ucla.edu>
10287
10288 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
10289 already. Let config.h define any nonstandard values.
10290
102912005-01-10 Paul Eggert <eggert@cs.ucla.edu>
10292
10293 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
10294 for the benefit of slower hosts. Problem reported by
10295 Nelson H. F. Beebe.
10296
102972005-01-07 Paul Eggert <eggert@cs.ucla.edu>
10298
10299 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
10300 being defined and not used.
10301 * data/lalr1.cc (yyparse): Likewise.
10302 Use "if (false)" rather than "if (0)".
10303
103042005-01-05 Paul Eggert <eggert@cs.ucla.edu>
10305
10306 * TODO: Mention that we should allow NUL bytes in tokens.
10307
103082005-01-02 Paul Eggert <eggert@cs.ucla.edu>
10309
10310 * src/scan-skel.l (<<EOF>>): Don't close standard output.
10311 Problem reported by Hans Aberg.
10312
103132005-01-01 Paul Eggert <eggert@cs.ucla.edu>
10314
10315 * src/getargs.c (version): Happy new year; update overall
10316 program copyright date from 2004 to 2005.
10317
10318 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
10319 Problem reported by Hans Aberg.
10320 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
10321 (Output file names.): Add a test for the case when standard output
10322 is closed.
10323
103242004-12-26 Paul Eggert <eggert@cs.ucla.edu>
10325
10326 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
10327 to fix an oversight in the Bison 2.0 manual.
10328
103292004-12-25 Paul Eggert <eggert@cs.ucla.edu>
10330
10331 * NEWS: Version 2.0. Reformat the existing news items since
10332 1.875, so that related items are grouped together.
10333 * configure.ac (AC_INIT): Bump version to 2.0.
10334 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
10335
10336 * tests/torture.at (Exploding the Stack Size with Alloca): Set
10337 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
10338 otherwise, we're not testing alloca. Unfortunately there's no
10339 simple way to consult HAVE_ALLOCA here.
10340
10341 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
10342 for yymsg, too.
10343
10344 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
10345 hand. This avoids a warning about comparing int to size_t when
10346 GCC warnings are enabled.
10347
103482004-12-22 Paul Eggert <eggert@cs.ucla.edu>
10349
10350 * NEWS: Bison-generated parsers no longer default to using the
10351 alloca function (when available) to extend the parser stack, due
10352 to widespread problems in unchecked stack-overflow detection.
10353 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
10354 responsibility to set it to a positive value. This lets the user
10355 specify a value that is not a preprocessor constant.
10356 * data/yacc.c (YYMAXDEPTH): Likewise.
10357 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
10358 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
10359 to be a compile-time constant. However, explain the constraints on it.
10360 Also, explain the constraints on YYINITDEPTH.
10361 (Table of Symbols): Explain that alloca is no longer the default.
10362 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
10363 to 1.
10364
10365 * doc/bison.texinfo (Location Default Action): Mention that n must
10366 be zero when k is zero. Suggested by Frank Heckenbach.
10367
103682004-12-22 Akim Demaille <akim@epita.fr>
10369
10370 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
10371 (parser::state_type, parser::semantic_type, parser::location_type):
10372 Private, not public.
10373 (parser::parse): Return ints, not bool.
10374 Returning a bool introduces a problem: 0 corresponds to false, and
10375 it seems weird to return false on success. Returning true changes
10376 the conventions for yyparse.
10377 Alternatively we could return void and send an exception.
10378 There is no clear consensus (yet?).
10379 (state_stack, semantic_stack, location_stack): Rename as...
10380 (state_stack_type, semantic_stack_type, location_stack_type): these.
10381 Private, not public.
10382 * tests/c++.at: New.
10383 * tests/testsuite.at, tests/Makefile.am: Adjust.
10384
103852004-12-21 Akim Demaille <akim@epita.fr>
10386
10387 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
10388
103892004-12-21 Akim Demaille <akim@epita.fr>
10390
10391 Don't impose std::string for filenames.
10392
10393 * data/lalr1.cc (b4_filename_type): New.
10394 (position::filename): Use it.
10395 (parser.hh): Move the inclusion of stack.hh and location.hh below
10396 the user code, so that needed headers for the filename type can be
10397 included first.
10398 Forward declare them before the user code.
10399 * tests/Makefile.am (check-local, installcheck-local): Pass
10400 TESTSUITEFLAGS to the TESTSUITE.
10401
104022004-12-20 Akim Demaille <akim@epita.fr>
10403
10404 Use more STL like names: my_class instead of MyClass.
10405
10406 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
10407 (SemanticStack, SemanticType, StateStack, StateType)
10408 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10409 (Parser::value): Rename as...
10410 (location_stack, location_type, rhs_number_type, semantic_stack)
10411 (semantic_type, state_stack, state_type, token_number_type, stack)
10412 (slice, traits, parser::yylloc, parser::yylval): these.
10413
10414 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10415
104162004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10417
10418 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10419 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10420
104212004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10422
10423 Remove uses of 'short int' and 'unsigned short int'. This raises
10424 some arbitrary limits. It uses more memory but nowadays that's
10425 not much of an issue.
10426
10427 This change does not affect the generated parsers; that's a different
10428 task, as some users will want to conserve memory there.
10429
10430 Ideally we should use size_t to represent all object counts, and
10431 something like ptrdiff_t to represent signed differences of object
10432 counts; but that will require more code-cleanup than I have the
10433 time to do right now.
10434
10435 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10436 Use size_t, not int or short int, to count objects.
10437 * src/closure.c (nritemset, closure): Likewise.
10438 * src/closure.h (nritemset, closure): Likewise.
10439 * src/nullable.c (nullable_compute): Likewise.

10445
10446 * src/gram.h (rule_number, rule): Use int, not short int.
10447 * src/output.c (prepare_rules): Likewise.
10448 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
10449 errs, reductions): Likewise.
10450 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
10451 Likewise.
10452 * src/tables.c (vector_number, tally, action_number,
10453 ACTION_NUMBER_MINIMUM): Likewise.
10454 * src/output.c (muscle_insert_short_int_table): Remove.
10455
104562004-12-17 Akim Demaille <akim@epita.fr>
10457
10458 * data/lalr1.cc: Extensive Doxygenation.
10459 (error_): Rename as...
10460 (error): this, since it is visible to the user.
10461 Adjust callers.
10462 (Parser::message): Now an automatic variable from...
10463 (Parser::yyreport_syntax_error_): here.
10464 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10465 Parser::error.
10466 * tests/input.at: Escape $.
10467
104682004-12-16 Paul Eggert <eggert@cs.ucla.edu>
10469
10470 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10471 Parenthesize rhs to avoid obscure problems with mistakes like
10472 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10473 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10474 b4_rhs_location): Likewise.
10475 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10476 b4_rhs_location): Likewise.
10477
104782004-12-16 Akim Demaille <akim@epita.fr>
10479
10480 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10481 yacc.c: be sure to stay within yycheck_.
10482 * tests/actions.at: Re-enable C++ tests.
10483
104842004-12-16 Akim Demaille <akim@epita.fr>

10487 real.
10488
104892004-12-16 Akim Demaille <akim@epita.fr>
10490
10491 Use #define to handle the %name-prefix.
10492
10493 * data/glr.c, data/yacc.c: Comment changes.
10494 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10495 so that one can refer to yylex in the parser file, and have it
10496 renamed, as is the case with other skeletons.
10497
104982004-12-16 Akim Demaille <akim@epita.fr>
10499
10500 Move lalr1.cc internals into yy*.

105202004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10521
10522 Fix some problems reported by twlevo at xs4all.
10523 * src/symtab.c (symbol_new): Report an error if the input grammar
10524 contains too many symbols. This is better than calling abort() later.
10525 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10526 (struct node, struct graph):
10527 Rename member expand to stretch. All uses changed.

10548 Take the %name-prefix into account.
10549 Reported by Alexandre Duret-Lutz.
10550
105512004-12-15 Akim Demaille <akim@epita.fr>
10552
10553 Simplify the C++ parser constructor.
10554
10555 * data/lalr1.cc (debug_): Rename as...
10556 (yydebug_): so that the parser's internals are always in the yy*
10557 pseudo namespace.
10558 Adjust uses.
10559 (b4_parse_param_decl): Remove the leading comma as it is now only
10560 called as unique argument list.
10561 (Parser::Parser): Remove the constructor accepting a location and
10562 an initial debugging level.
10563 Remove from the other ctor the argument for the debugging level.
10564 (debug_level_type, debug_level, set_debug_level): New.
10565
10566 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
10567 constructor calls.
10568
105692004-12-15 Akim Demaille <akim@epita.fr>

10571 Remove b4_root related material: failure experiment
10572 (which goal was to allow to derive from a class).
10573
10574 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
10575 definitions and uses.
10576
105772004-12-14 Paul Eggert <eggert@cs.ucla.edu>
10578
10579 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
10580 not 2, since it's not portable to subtract 1 from the start of an
10581 array. The new item 0 is never set or used. All uses changed.
10582
10583 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
10584 the default definition of YYLLOC_DEFAULT. Problem reported
10585 by Frank Heckenbach.
10586
105872004-12-12 Paul Eggert <eggert@cs.ucla.edu>
10588
10589 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
10590 the normal case and one for the error case. Just use the
10591 first one uniformly. Problem reported by Frank Heckenbach.
10592 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
10593 use exactly the same macro in both places.
10594 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
10595 so that the normal-case YYRHSLOC works for the error case too.
10596 All uses changed.
10597 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
10598 (YYLLOC_DEFAULT): Use the same macro as glr.c.
10599 * doc/bison.texinfo (Location Default Action): Don't claim that
10600 we have an array of locations. Use the same macro for both glr
10601 and lalr parsers. Mention YYRHSLOC. Mention what happens when
10602 the index is 0.
10603
106042004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10605
10606 * HACKING: Update email addresses to send announcements to.
10607
10608 * configure.ac (AC_INIT): Bump version to 1.875f.
10609
106102004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10611
10612 * NEWS: Version 1.875e.
10613 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
10614
10615 * src/scan-skel.l: Include "complain.h", for "fatal".
10616
10617 * src/relation.h (relation_print, relation_digraph):
10618 Relation sizes are of type relation_node, not size_t (this is
10619 merely a doc fix, since the two types are equivalent).
10620 (relation_transpose): Relation sizes are of type relation_node,
10621 not int.
10622 * src/relation.c: Likewise.
10623 (top, infinity): Now of type relation_node, not int.
10624 (traverse, relation_transpose): Use relation_node, not int.
10625
10626 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
10627 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
10628 (yyparse): Remove unused local introduced in 2004-10-25 patch.
10629
10630 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
10631 specifying whether the test should be skipped. Use it tp
10632 specify that the [%defines %skeleton "lalr1.cc"] tests currently
10633 fail on some hosts, and should be skipped.
10634
106352004-12-08 Paul Eggert <eggert@cs.ucla.edu>
10636
10637 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
10638 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
10639 unless otherwise specified below.
10640
10641 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
10642 to allocate kernel_base, kernel_items, kernel_size, since
10643 they needn't be initialized to 0.
10644 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
10645 * src/closure.c (new_closure): Likewise, for itemset.
10646 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
10647 * src/lalr.c (set_goto_map): Likewise, for temp_map.
10648 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
10649 (build_relations): Likewise for edge, states1, includes.
10650 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
10651 * src/reader.c (packgram): Likewise, for ritem, rules.
10652 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
10653 * src/relation.c (relation_digraph): Likewise for VERTICES.
10654 (relation_transpose): Likewise for new_R, end_R.
10655 * src/symtab.c (symbols_token_translations_init): Likewise for
10656 token_translations.
10657 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
10658 (token_actions): Likewise for yydefact, actrow, conflrow,
10659 conflict_list.
10660 (save_column): Likewise for froms[symno], tos[symno].
10661 (goto_actions): Likewise for state_count.
10662 (pack_table): Likewise for base, pos, check.
10663 (tables_generate): Likewise for width.
10664
10665 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
10666 for initial core. Just have a separate core, so we needn't worry
10667 about whether kernel_size and kernel_base are initialized.
10668
10669 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
10670 kernel_size, kernel_items): Remove unnecessary initialization.
10671 * src/conflicts.c (conflicts): Likewise.
10672 * src/derives.c (derives): Likewise.
10673 * src/muscle_tablc (muscle_insert): Likewise.
10674 * src/relation.c (relation_digraph): Likewise.
10675 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
10676 conflrow, conflict_table, conflict_list, table, check):
10677 Likewise.
10678
10679 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
10680 This is because all callers pass unsigned int.
10681 * src/closure.h (new_closure): Likewise.
10682
10683 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
10684 (build_relations): Initialize includes[i] in all cases.
10685 * src/reader.c (packgram): Always initialize rules[ruleno].prec
10686 and rules[ruleno].precsym. Initialize members in order.
10687 * src/relation.c (relation_transpose): Always initialize new_R[i]
10688 and end_R[i].
10689 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
10690
10691 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
10692 conflict_list[0] was always 0, but now it isn't initialized.
10693
10694 * src/table.c (table_grow): When conflict_table grew, the grown
10695 area wasn't cleared. Fix this.
10696
10697 * lib/.cvsignore: Add strdup.c, strdup.h.
10698 * m4/.cvsignore: Add strdup.m4.
10699
107002004-12-07 Paul Eggert <eggert@cs.ucla.edu>
10701
10702 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
10703 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
10704 GOTO_NUMBER_MAXIMUM, since we occasionally compute
10705 ngotos + 1 without checking for overflow.
10706 (build_relations): Use END_NODE, not -1, to denote end of edges.
10707 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
10708 build_relations): Use goto_number, not int, for goto numbers.
10709 * src/tables.c (save_column, default_goto): Likewise.
10710
107112004-11-23 Akim Demaille <akim@epita.fr>
10712
10713 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
10714 of #defining from yystype.
10715 Don't typedef yystype, C++ does not need it.
10716 This lets it possible to forward declare it as union.
10717
107182004-11-23 Paul Eggert <eggert@cs.ucla.edu>
10719
10720 * bootstrap (gnulib_modules): Add extensions.
10721 Problem reported by Jim Meyering.
10722
107232004-11-22 Paul Eggert <eggert@cs.ucla.edu>
10724
10725 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
10726 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
10727 src/system.h, src/tables.c: XFREE -> free, to accommodate
10728 recent change to gnulib xalloc.h.
10729 Problem reported by Jim Meyering.
10730
107312004-11-17 Akim Demaille <akim@epita.fr>
10732
10733 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
10734
107352004-11-17 Akim Demaille <akim@epita.fr>,
10736 Alexandre Duret-Lutz <adl@gnu.org>
10737
10738 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
10739 changes.
10740 (YYCDEBUG): Adjust.
10741 Use it instead of cdebug_.
10742 (Parser::debug_stream, Parser::set_debug_stream): New.
10743 (Parser::symprint_): Define cdebug_ for temporary backward
10744 compatibility.
10745 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
10746 debug_stream ().
10747
107482004-11-17 Akim Demaille <akim@epita.fr>
10749
10750 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
10751 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
10752 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
10753 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

107552004-10-27 Paul Eggert <eggert@cs.ucla.edu>
10756
10757 * data/glr.c (yyloc_default): Remove; not used.
10758 Problem reported by Frank Heckenbach.
10759
107602004-10-25 Akim Demaille <akim@epita.fr>
10761
10762 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
10763 Introduce another definition to address simple location arrays.
10764 (yyGLRStack): New member: yyerror_range.
10765 (yyrecoverSyntaxError, yyparse): Update it.
10766 (yyrecoverSyntaxError): Use it when shifting the error token to
10767 have an accurate range, equivalent to the one computed by both
10768 yacc.c and lalr1.cc.
10769 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
10770 that column numbers start at column 0, as per GNU Coding
10771 Standards, the others tests, and the doc.
10772 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
10773 Adjust to the above change (first column is 0).
10774 And adjust the location of the "<error>", now covering the whole
10775 line.
10776
107772004-10-22 Akim Demaille <akim@epita.fr>
10778 and Paul Eggert <eggert@cs.ucla.edu>
10779
10780 Remove some arbitrary limits on goto numbers and relations.
10781 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
10782 initial values, since they're never used.
10783 (set_goto_map): ngotos is now unsigned, so test for overflow
10784 by seeing whether it wraps around to zero.
10785 * src/lalr.h (goto_number): Now size_t, not short int.
10786 (GOTO_NUMBER_MAXIMUM): Remove.
10787 * src/relation.c (relation_print, traverse, relation_transpose):
10788 Check for END_NODE rather than looking at sign.
10789 * src/relation.h (END_NODE): New macro.
10790 (relation_node): Now size_t, not short int.
10791
107922004-10-22 Paul Eggert <eggert@cs.ucla.edu>
10793
10794 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
10795 keyword, not an identifier. Problem reported by Baron Schwartz in
10796 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
10797
107982004-10-11 Akim Demaille <akim@epita.fr>
10799
10800 * src/symtab.c (symbol_check_alias_consistency): Also check
10801 type names, destructors, and printers.
10802 Reported by Alexandre Duret-Lutz.
10803 Recode the handling of associativity and precedence in terms
10804 of symbol_precedence_set.
10805 Accept no redeclaration at all, not even equal to the previous
10806 value.
10807 (redeclaration): New.
10808 Use it to factor redeclaration complaints.
10809 (symbol_make_alias): Don't set the type of the alias, let
10810 symbol_check_alias_consistency do it as for other features.
10811 * src/symtab.h (symbol): Add new member prec_location, and
10812 type_location.
10813 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
10814 * tests/input.at (Incompatible Aliases): New.
10815
108162004-10-09 Paul Eggert <eggert@cs.ucla.edu>
10817
10818 .cvsignore fixes to accommodate gnulib changes,
10819 and the practice of naming build directories "_build".
10820 * .cvsignore: Add "_*". Sort.
10821 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
10822 * m4/.cvsignore: Add "*_gl.m4".
10823
108242004-10-06 Akim Demaille <akim@epita.fr>
10825
10826 * src/parse-gram.y (add_param): Fix the truncation of trailing
10827 spaces.
10828
108292004-10-05 Akim Demaille <akim@epita.fr>
10830
10831 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10832 whether the reducion was empty or not. This leaves room to
10833 improve the use of YYLLOC_DEFAULT in such a case.
10834 lalr1.cc is still experimental, so changing this is acceptable.
10835 And finally, there are probably not many users who changed the
10836 handling of locations in GLR, so changing is admissible too.
10837
10838 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
10839 empty reduction, set @$ to an empty location ending the previously
10840 stacked symbol.
10841 Adjust uses to make sure the code is triggered on empty
10842 reductions.
10843 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
10844 expected output: empty reductions have empty locations.
10845
108462004-09-29 Akim Demaille <akim@epita.fr>
10847
10848 * data/lalr1.cc: Move towards a more standard C++ coding style
10849 for templates: Class < T > -> Class<T>.
10850
108512004-09-29 Akim Demaille <akim@epita.fr>
10852
10853 * data/lalr1.cc: Reinstall the former ctor, for sake of
10854 compatibility, but warn it will be removed.
10855 Move towards a more standard C++ coding style (i.e., type *var ->
10856 type* var).
10857
108582004-09-27 Paul Eggert <eggert@cs.ucla.edu>
10859
10860 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
10861 since it's less likely to work if NULs are involved in the future.
10862
108632004-09-27 Akim Demaille <akim@epita.fr>
10864
10865 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
10866
108672004-09-27 Akim Demaille <akim@epita.fr>
10868
10869 * data/lalr1.cc (b4_parse_param_decl_1): New.
10870 (b4_parse_param_decl): Use it to have different names between attribute
10871 and argument names.
10872 (b4_cc_constructor_call): Likewise.
10873
108742004-09-24 Akim Demaille <akim@epita.fr>
10875
10876 * src/parse-gram.y (add_param): Strip the leading and trailing
10877 blanks from a formal argument declaration.
10878 (YY_LOCATION_PRINT): New.
10879
108802004-09-24 Akim Demaille <akim@epita.fr>
10881
10882 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
10883 after the location.
10884
108852004-09-24 Akim Demaille <akim@epita.fr>
10886
10887 * doc/bison.texinfo (Table of Symbols): Sort.
10888
108892004-09-21 Akim Demaille <akim@epita.fr>
10890
10891 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
10892 the useless parentheses.
10893 Suggested by Paul Eggert.
10894
108952004-09-20 Akim Demaille <akim@epita.fr>
10896
10897 Let the initial-action act on the look-ahead, and use it for the
10898 "initial push" (corresponding to an hypothetical beginning-of-file).
10899 And let lalr1.cc honor %initial-action.
10900
10901 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
10902 example.
10903 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10904 (Parser::Parser): Remove the ctor that used to initialize it.
10905 (Parser::parse): Like in the other skeletons, issue the "starting
10906 parse" message before any action.
10907 Honor %initial-action.
10908 Initialize the stacks with the lookahead.
10909 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10910 look-ahead.
10911 Push them in the stacks.
10912 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
10913
109142004-09-20 Akim Demaille <akim@epita.fr>
10915
10916 * doc/bison.texinfo (Initial Action Decl): New.
10917
109182004-09-20 Akim Demaille <akim@epita.fr>
10919
10920 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
10921 clearer criterion to define it.
10922 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
10923 When reducing on an empty RHS, use the latest stacked location as
10924 location.
10925 yylloc is not always available.
10926 * data/glr.c: Likewise.
10927 Also, honor initial-actions.
10928
109292004-09-20 Akim Demaille <akim@epita.fr>
10930
10931 * data/yacc.c (YY_LOCATION_PRINT): New.
10932 Define when we know YYLTYPE's structure, i.e., when the default
10933 YYLLOC_DEFAULT is used.
10934 * data/c.m4 (b4_yysymprint_generate): Use it.
10935 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
10936 value of the result.
10937 (error_start_): Replace with...
10938 (error_range_): this location array.
10939 This allows to replace code relying on the implementation of
10940 locations by portable code.
10941 * data/yacc.c (yylerrsp): Replace with...
10942 (yyerror_range): this.
10943 Every time a token is popped, update yyerror_range[0], to have an
10944 accurate location for the error token.
10945 * data/glr.c (YY_LOCATION_PRINT): New.
10946 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
10947 deference a pointer.
10948 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
10949 report the location in %printers.
10950
10951 * src/scan-skel.l: Instead of abort, report error messages to ease
10952 understanding skeleton scanning failures.
10953
109542004-09-16 Akim Demaille <akim@epita.fr>
10955
10956 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
10957 (iterator, const_iterator): these, to be more in the C++ spirit.
10958 Also, return reverse iterators so that when displaying the stack
10959 we display its bottom first.
10960 (Parser::stack_print_, Parser::reduce_print_): Match the messages
10961 from yacc.c.
10962 We should probably use vector here though.
10963
109642004-09-16 Akim Demaille <akim@epita.fr>
10965
10966 Have more complete shift traces.
10967
10968 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
10969 to report Shifts instead of ad hoc YYDPRINTF invocations,
10970 including for the error token.
10971 * data/lalr1.cc (symprint_): Output the location.
10972 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10973 output the location within the %printer.
10974 Activate GLR tests, at least to make sure they compile properly.
10975 They still don't pass though.
10976 * tests/calc.at: Adjust expect verbose output, since now "Entering
10977 state..." is on a different line than the "Shifting" message.
10978
109792004-09-08 Akim Demaille <akim@epita.fr>
10980
10981 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10982 Bison directive from the Bison file to the invocation of this
10983 macro, so that these directives are passed to
10984 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10985 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10986 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10987 the extra Bison directives instead of the whole series.
10988 Change the grammar so that there are recoverable errors, and
10989 unrecoverable errors. Now we can have the parser give up before
10990 consuming the whole input. As a result we now can observe that
10991 the lookahead is freed when needed.
10992 Change the parser source to parse argv[1] instead of a hard coded
10993 string.
10994 Simplify yylex, and give a value and location to EOF.
10995 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10996 passed directives already coded in the file.
10997 Add some tests to check the location of "error".
10998 For some tests, the C++ parser is correct, and not yacc.c.
10999 For other tests, they provide different, but unsatisfying, values,
11000 so keep the C++ value so that at least one parser is "correct"
11001 according to the test suite.
11002 (Actions after errors): Remove, this is subsumed by the
11003 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

11068 * bootstrap (gnulib_modules): Add xalloc-die.
11069 Set LC_ALL=C so that file names sort consistently.

11071 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
11072 uintmax_t.m4, ulonglong.m4.
11073 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
11074 po.m4 since we are now using _gl.m4 instead.
11075
110762004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
11077
11078 * src/scan-action.l: Remove. Scanning of semantic actions is

11089
11090 Fix bug with non-%union parsers that have printers or destructors,
11091 which led to a Bison core dump. Reported by Peter Fales in
11092 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
11093
11094 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
11095 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
11096 not to our own type.

11098 Don't assume %union.
11099 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
11100 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
11101 UNION-FLAG. All callers changed.
11102 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
11103 Use type char, not unsigned int, when declaring an array of char;
11104 this lets us remove a cast.

11106
111072004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11108
11109 * doc/bison.texinfo: Minor editorial changes, mostly to the new
11110 GLR writeups. E.g., avoid frenchspacing and the future tense,
11111 change "lookahead" to "look-ahead", and change "wrt" to "with
11112 respect to".
11113
111142004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11115
11116 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
11117 New sections, split off from the GLR Parsers section. Put the new
11118 Simple GLR Parser near the start of the GLR section, for clarity.
11119 Rewrite connective text.
11120
111212004-06-21 Frank Heckenbach <frank@g-n-u.de>

11180
11181 Spent a few hours checking out which prerequisite versions the
11182 current sources actually require. I went all the way back to
11183 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
11184 a seemingly endless set of combinations of versions more recent
11185 than that. The bottom line is that the current sources require
11186 fairly recent versions of the build tools, and it'll be some work
11187 to change this.
11188 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
11189 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
11190 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
11191 Add comments explaining why those particular versions are
11192 currently needed.
11193
11194 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
11195 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
11196 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
11197
11198 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
11199 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
11200
112012004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11202
11203 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
11204 0.11.5. Suggested by Bruno Haible.
11205 * bootstrap: Remove gettext version checking.
11206
11207 * doc/bison.texinfo (Decl Summary): Also mention that %union
11208 can depend on prerequisite types. Problem reported by Tim
11209 Van Holder.
11210
112112004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11212
11213 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
11214 * README-alpha: Don't tell people not to package this.
11215
11216 * bootstrap: Don't assume $(...) works; use `...` instead.
11217 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
11218 gettext better.
11219
11220 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
11221 put into the -d output file, and mention what to do if YYSTYPE is
11222 defined as a macro.
11223
112242004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11225
11226 Undo change made earlier today: it caused autopoint to not bring
11227 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
11228 autopoint's.
11229
11230 * bootstrap: Check that gettext version matches what's in
11231 configure.ac. Warn users to ignore robots.txt ERROR 404.
11232 * bootstrap: Undo today's earlier change (logged below).
11233 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
11234
11235 The gettext version checking is causing more trouble than it's
11236 curing; remove it. Problem reported by Paul Hilfinger.
11237
11238 * bootstrap: Issue a warning that one can expect a message
11239 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
11240 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
11241
112422004-05-23 Paul Eggert <eggert@cs.ucla.edu>
11243
11244 Ensure that the C++ compiler used for testing actually works on a
11245 simple test program; if not, skip the C++-related tests. Problem
11246 reported by Vin Shelton in:
11247 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

11253
112542004-05-21 Paul Eggert <eggert@cs.ucla.edu>
11255
11256 * data/glr.c (yylloc): Output this macro even if locations are not
11257 being generated, as the GLR parser needs it even in that case.
11258 Problem reported by Troy A. Johnson
11259 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
11260
11261 * configure.ac (AC_INIT): Update to 1.875e.
11262
112632004-05-21 Paul Eggert <eggert@cs.ucla.edu>
11264
11265 * NEWS: Version 1.875d.
11266 * configure.ac (AC_INIT): Likewise.
11267 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
11268
11269 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
11270 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
11271 lalr1.cc runs afoul of the first, and the last two are no longer
11272 supported by GCC 3.4.0.
11273 * README: Mention GNU m4 1.4 or later; mention m4 patches.
11274 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
11275
112762004-05-06 Paul Eggert <eggert@cs.ucla.edu>
11277
11278 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
11279 unsigned int, for compatibility with latest gnulib hash module.
11280 * src/state.c (state_hash, state_hasher): Likewise.
11281 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.

11290 character and string literals.
11291 (unexpected_end): New function.
11292 (unexpected_eof): Use it.

11301 Remove more 'intl'-related files.
11302 Don't DEFUN AM_INTL_SUBDIR twice.
11303
11304 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
11305 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
11306 strtoul.c.
11307 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
11308 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
11309 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
11310 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
11311 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
11312 * src/.cvsignore: Add *.output.
11313
11314 * src/parse-gram.y: Put copyright notice inside %{ %} so it
11315 gets copied to the output file.
11316
113172004-04-28 Paul Eggert <eggert@twinsun.com>
11318
11319 Get files from the gnulib and po repositories, instead of relying
11320 on them being in our CVS. Upgrade to latest versions of gnulib
11321 and Automake.
11322
11323 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
11324 * bootstrap: Bootstrap from gnulib and po repositories.
11325 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11326 * README-cvs: Document these changes. Remove version numbers from
11327 mentions of build tools, since they change so often. Mention Flex.
11328
11329 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
11330 (gl_USE_SYSTEM_EXTENSIONS): Add.
11331 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
11332 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
11333 does this for us.
11334 (AC_ISC_POSIX): Remove; we no longer support this
11335 ancient OS, as it gets in the way of latest Autoconf & gnulib.
11336 (AC_HEADER_STDC): Remove: we now assume C89 or better.
11337 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
11338 Do not check for C89 headers, except for locale.h which is used
11339 by the Yacc library and must port to K&R hosts.
11340 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
11341 Do not check for C89 functions, except for setlocale which is
11342 used by the Yacc library.
11343 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
11344 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

11348 AM_GNU_GETTEXT): Remove; now done by:
11349 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
11350 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
11351 for us.
11352
11353 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
11354 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
11355 Define to empty, as gnulib.mk will do the rest for us.
11356 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
11357 for us.
11358 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
11359 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
11360
11361 * src/files.c: Include gnulib's xstrndup.h.
11362
11363 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
11364 (REALLOC): Use xnrealloc, for likewise.
11365 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
11366 (strnlen, memrchr): Remove decls; functions no longer used.
11367 Include <stpcpy.h>.
11368
11369 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

11390 Remove, as these files are now generated automatically
11391 by bootstrap or automake.
11392
11393 * po/ChangeLog: Remove: all but one entry was a duplicate
11394 of this file, and I moved that 2000-11-02 entry here.
11395
11396 * config/.cvsignore: Add Makefile, depcomp, install-sh.
11397 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

11407 xstrndup.h.
11408 * m4/.cvsignore: Remove Makefile, Makefile.in. Add alloca.m4,
11409 dirname.m4, dos.m4, error.m4, getopt.m4, hash.m4, mbrtowc.m4,

11414
11415
11416 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
11417 support it. (The latest stable gzip doesn't.)
11418
114192004-04-27 Paul Eggert <eggert@twinsun.com>
11420
11421 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
11422 case, as stos_ is now used by destructors due to the 2004-02-09
11423 change.
11424
11425 Remove more K&R C support.
11426 * lib/libiberty.y (PARAMS): Remove. All uses removed.
11427 * lib/subpipe.c (errno): Remove decl.
11428 Include <stdlib.h> unconditionally.
11429 (EXIT_FAILURE): Remove macro.
11430 * src/complain.c (vfprintf, strerror): Remove.
11431 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
11432 unconditionally.
11433 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
11434 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
11435 (strchr, strspn, memchr): Remove decls.
11436 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
11437 unconditionally. Do not declare perror.
11438 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
11439 unconditionally.
11440
11441 * src/complain.c (_): Remove useless defn, as system.h defines this.
11442
11443 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
11444 with latest obstack.h.
11445 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
11446 to procedure types, as obstack.h now does that for us.
11447 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
11448
11449 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
11450 so that this include file can stand alone.
11451 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
11452 does this now. Include subpipe.h first after config.h, to
11453 test whether it can stand alone.
11454
11455 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
11456 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
11457 unused declaration.
11458
11459 * tests/synclines.at (%union synch line): Put a dummy member in
11460 the union, because empty unions aren't allowed in C. Caught
11461 by GCC 3.4.0.
11462
114632004-04-13 Jim Meyering <jim@meyering.net>
11464
11465 * src/conflicts.c (conflicts_print): Correct format string typo:
11466 use `%%' to produce literal `%'. (trivial change)
11467
114682004-03-30 Paul Eggert <eggert@twinsun.com>
11469
11470 * src/getargs.c (version): Update copyright year to 2004.
11471
11472 * data/c.m4 (b4_int_type): Use 'short int' rather than
11473 'short', and similarly for 'long', 'unsigned', etc.
11474 * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum,
11475 yygetLRActions, yyprocessOneStack, yyrecoverSyntaxError,
11476 yy_yypstack, yydumpstack): Likewise.
11477 * data/lalr1.cc (user_token_number_max_, user_token_number_max_,
11478 translate_, seq_, [], pop, Slice, range_, operator+, operator+=):
11479 Likewise.
11480 * data/yacc.c (b4_int_type, yyss, YYSTACK_BYTES, yysigned_char,
11481 yy_stack_print, yyparse): Likewise.

11498 * src/state.h (state_number, transitions, errs, reductions,
11499 struct state): Likewise.
11500 * src/symtab.h (symbol_number, struct symbol): Likewise.
11501 * src/tables.c (vector_number, tally, action_number,
11502 default_goto, goto_actions): Likewise.
11503 * tests/existing.at (GNU Cim Grammar): Likewise.
11504 * tests/regression.at (Web2c Actions): Likewise.
11505

11508
115092004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
11510
11511 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
11512 (declaration): Replace expected_conflicts with expected_sr_conflicts.
11513 Add %expect-rr rule.
11514
11515 * src/scan-gram.l: Recognize %expect-rr.
11516
11517 * src/conflicts.h (expected_sr_conflicts): Rename from
11518 expected_conflicts.
11519 (expected_rr_conflicts): Declare.
11520
11521 * src/conflicts.c (expected_sr_conflicts): Rename from
11522 expected_conflicts.
11523 (expected_rr_conflicts): Define.
11524 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
11525 for GLR parsers.
11526 Use expected_sr_conflicts in place of expected_conflicts.
11527 Warn if expected_rr_conflicts used in non-GLR parser.
11528
11529 * doc/bison.texinfo: Add documentation for %expect-rr.
11530
115312004-03-08 Paul Eggert <eggert@gnu.org>
11532
11533 Add support for hex token numbers. Suggested by Odd Arild Olsen in
11534 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
11535
11536 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
11537 in lalr1.cc.
11538 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
11539 * src/scan-gram.l (scan_integer): New function.
11540 ({int}): Use it.
11541 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
11542 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
11543 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
11544 Say "long int", not "long", for uniformity with GNU style.
11545
115462004-02-25 Paul Eggert <eggert@twinsun.com>
11547
11548 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
11549 compilers. This fixes a problem with Intel's C++ compiler being
11550 chatty, reported by Guido Trentalancia in
11551 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
11552
115532004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
11554
11555 Support %destructor and merge error locations in lalr1.cc.
11556
11557 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
11558 (Parser::stos_): Define unconditionally.
11559 (Parser::destruct_): New method. Generate its body with
11560 b4_yydestruct_generate.
11561 (Parser::error_start_): New attribute.
11562 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
11563 token which are discarded.
11564 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
11565 error_start_ when erroneous token are discarded.
11566 (Parser::parse) <yyerrlab1>: Compute the location of the error
11567 token so that it covers all the discarded tokens.
11568 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
11569 it can be called with `%skeleton "lalr1.cc"', and do that.
11570
115712004-02-02 Paul Eggert <eggert@twinsun.com>
11572
11573 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
11574 $(top_srcdir)/lib and ../lib. This fixes a bug reported
11575 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
11576 There's no need to mention top_builddir since Automake does that
11577 for us.
11578 (INCLUDES): Remove, as Automake says it's obsolescent.
11579 Contents migrated into AM_CPPFLAGS as described above.
11580 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
11581
115822004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11583
11584 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
11585 (yyreportSyntaxError): Handle case where lookahead token is
11586 YYEMPTY.
11587
115882004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11589
11590 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
11591 resulting parsers are compilable with C++.
11592
115932003-12-23 Paul Eggert <eggert@twinsun.com>
11594
11595 * config/depcomp, config/install-sh: Sync with Automake 1.8.
11596 * src/output.c (output_skeleton): Rename local var.
11597 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
11598 Bison tokens, as this runs afoul of the 2003-10-07 change that
11599 disallowed NUL bytes in character constants or string literals.
11600
11601 * tests/local.at: Require Autoconf 2.59's Autotest.
11602 * tests/testsuite.at: Don't include local.at, since we now assume
11603 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
11604 including it.
11605 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
11606 multiple inclusion warnings.
11607
116082003-12-02 Akim Demaille <akim@epita.fr>
11609
11610 * doc/bison.texinfo (How Can I Reset the Parser): More about start
11611 conditions.
11612 From Bruno Haible.
11613
116142003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
11615
11616 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
11617
116182003-10-07 Paul Eggert <eggert@twinsun.com>
11619
11620 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
11621 if testsuite doesn't exist.
11622
11623 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
11624 literals, unfortunately.
11625 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
11626 Complain about NUL bytes in character constants or string literals.
11627
116282003-10-05 Paul Eggert <eggert@twinsun.com>
11629
11630 * NEWS: Don't document %no-default-prec, as it's still
11631 too experimental.
11632 * doc/bison.texinfo: Document %no-default-prec only if
11633 the defaultprec flag is set. Normally it's not.
11634
116352003-10-04 Paul Eggert <eggert@twinsun.com>
11636
11637 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
11638 non-modifiable lvalue, instead of a modifiable one.
11639 * doc/bison.texinfo (Actions): Document that $$ can
11640 be assigned to. Do not claim that $$ and $N are
11641 array element references: user code should not rely on this.
11642
116432003-10-01 Paul Eggert <eggert@twinsun.com>
11644
11645 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
11646 (grammar_declaration): Use it.
11647 * src/scan-gram.l: New token %no-default-prec.
11648 * tests/conflicts.at: Revamp tests to use %no-default-prec.
11649 * NEWS, doc/bison.texinfo: Document the above.
11650
116512003-10-01 Akim Demaille <akim@epita.fr>
11652
11653 VCG no longer supports long_straight_phase.
11654
11655 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
11656 * src/print_graph.c (print_graph): Adjust.
11657
116582003-09-30 Frank Heckenbach <frank@g-n-u.de>
11659 and Paul Eggert <eggert@twinsun.com>
11660
11661 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
11662 Table of Symbols): Document %default-prec.
11663 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
11664 (grammar_declaration): Set default_prec on %default-prec.
11665 * src/scan-gram.l (%default-prec): New token.
11666 * src/reader.h (default_prec): New flag.
11667 * src/reader.c: Likewise.
11668 (packgram): Handle it.
11669 * tests/conflicts.at (%default-prec without %prec,
11670 %default-prec with %prec, %default-prec 1): New tests.
11671
116722003-09-30 Paul Eggert <eggert@twinsun.com>
11673
11674 * tests/testsuite.at: Include local.at, not input.at, fixing
11675 a typo in the 2003-08-25 patch.
11676
116772003-08-27 Akim Demaille <akim@epita.fr>
11678
11679 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
11680 GCC warnings.
11681
116822003-08-26 Akim Demaille <akim@epita.fr>
11683
11684 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
11685 "<\#" to avoid magic from Gnus when posting parts of this script.
11686
116872003-08-26 Akim Demaille <akim@epita.fr>
11688
11689 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
11690 (Parser::parse): here.
11691 Adjust: nerrs and errstatus is now replaced by...
11692 (Parser::nerrs_, Parser::errstatus_): New.
11693
116942003-08-25 Akim Demaille <akim@epita.fr>
11695
11696 * config/announce-gen, Makefile.cfg: New.
11697 * Makefile.am: Adjust.
11698 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
11699 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
11700
117012003-08-25 Akim Demaille <akim@epita.fr>
11702
11703 When reducing initial empty rules, Bison parser read an initial
11704 location that is not defined. This results in garbage, and that
11705 affects Bison's own parser. Therefore we need (i) to extend Bison
11706 to support a means to initialize this location, and (ii) to use
11707 this CVS Bison to fix CVS Bison's parser.
11708
11709 * src/reader.h, reader.c (epilogue_augment): Remove, replace
11710 with...
11711 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
11712 * src/parse-gram.y: Adjust.
11713 (%initial-action): New.
11714 (%error-verbose): Since we require CVS Bison, there is no reason
11715 not to use it.
11716 * src/scan-gram.l: Adjust.
11717 * src/Makefile.am (YACC): New, to make sure we use our own parser.
11718 * data/yacc.c (yyparse): Use b4_initial_action.
11719
117202003-08-25 Akim Demaille <akim@epita.fr>
11721
11722 * doc/bison.texinfo: Don't promote stdout for error messages.
11723
117242003-08-25 Akim Demaille <akim@epita.fr>
11725
11726 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
11727 From Alexandre Duret-Lutz.

11736 Use them.
11737
117382003-08-25 Akim Demaille <akim@epita.fr>
11739
11740 * data/lalr1.cc (Parser::reduce_print_): New.

11742
117432003-08-25 Akim Demaille <akim@epita.fr>
11744
11745 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
11746 error recovery loops. This patch is based on
11747 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
11748 Also, augment the similarity between lalr1.cc and yacc.c.
11749 Note: the locations of error recovery rules are not correct yet.
11750
11751 * data/lalr1.cc: Comment changes to augment the similarity between
11752 lalr1.cc and yacc.c.
11753 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
11754 (yyerrlab1): Remove, but where it used to be (now the bottom part of
11755 yyerrlab), when hitting EOF, pop the whole stack here instead of
11756 merely falling thru the default error handling mechanism.
11757 (yyerrorlab): New label, with the old contents of YYERROR,
11758 plus the following change: pop the stack of rhs corresponding
11759 to the production that invoked YYERROR. That is how Yacc
11760 behaves (required by POSIX).
11761 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
11762 fail.
11763
117642003-08-25 Akim Demaille <akim@epita.fr>
11765
11766 Tune local.at so that people can "autom4te -l autotest calc.at -o
11767 calc" for instance, to extract a sub test suite.
11768
11769 * tests/testsuite.at: Move the initialization, Autotest version
11770 requirement, and AT_TESTED invocation into...
11771 * tests/local.at: here.
11772 * tests/testsuite.at: Include it for compatibility with Autoconf
11773 2.57.
11774 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
11775 be ignore.
11776
117772003-08-04 Paul Eggert <eggert@twinsun.com>
11778
11779 Rework code slightly to avoid gcc -Wtraditional warnings.
11780 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
11781 The returned value is now stored in *YY0. All callers changed.
11782 * src/output.c (merge_output): Adjust to the above change.
11783
117842003-07-26 Paul Eggert <eggert@twinsun.com>
11785
11786 * data/glr.c (YYASSERT): New macro.
11787 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
11788 yyresolveStates, yyprocessOneStack):
11789 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
11790 Derived from a suggestion by Frank Heckenbach.
11791
117922003-07-25 Paul Eggert <eggert@twinsun.com>
11793
11794 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
11795 for portability to K&R C (after ansi2knr, presumably). See
11796 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
11797 by Frank Heckenbach, though I have omitted the structure-initialization
11798 part of his glr-knr.diff patch since I recall that the Portable
11799 C Compiler didn't require that change.
11800
11801 Let the user specify how to allocate and free memory.
11802 Derived from a suggestion by Frank Heckenbach in
11803 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
11804 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
11805 All uses of free, malloc, realloc changed to use these macros,
11806 and unnecessary casts removed.
11807 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
11808
118092003-07-06 Matthias Mann <MatthiasMann@gmx.de>
11810
11811 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
11812 use s.empty() rather than s == "" to test for empty string; see
11813 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
11814 (trivial change)
11815
118162003-06-25 Akim Demaille <akim@epita.fr>
11817
11818 * config/depcomp, config/install-sh: Update from masters.
11819
118202003-06-20 Paul Eggert <eggert@twinsun.com>
11821
11822 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
11823 and return properly parenthesized result.
11824 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
11825 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
11826 Remove unnecessary parentheses from uses.
11827 * doc/bison.texinfo (Location Default Action): Describe the
11828 conventions for parentheses.
11829
118302003-06-19 Paul Eggert <eggert@twinsun.com>
11831
11832 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
11833 yyreportTree): Do not assume that size_t is the same width as int,
11834 when printing sizes. Print sizes using an unsigned format.
11835 Problem reported by Frank Heckenbach in
11836 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
11837
11838 Port to Forte Developer 7 C compiler.
11839 * data/glr.c (struct YYLTYPE): If locations are not being used,
11840 declare a single dummy member, as empty structs do not conform
11841 to the C standard.
11842 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
11843 the Forte Developer 7 C compiler complains that end-of-loop
11844 code is not reached.
11845
118462003-06-17 Paul Eggert <eggert@twinsun.com>
11847
11848 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
11849 avoid warnings from picky compilers about redefinition of PARAMS.
11850
118512003-06-17 Paul Eggert <eggert@twinsun.com>
11852
11853 Version 1.875b.
11854
11855 * NEWS: Document 1.875b.
11856
11857 * lib/bbitset.h: Do not include config.h; that's the includer's job.
11858 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
11859 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
11860 Don't use 'index' in comments, as it's a builtin fn on some hosts.
11861 * lib/bitset_stats.c: Include gettext.h unconditionally, as
11862 per recent gettext manual's suggestion.
11863 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
11864 Use prototypes, not old-style definitions.
11865 * lib/lbitset.c (lbitset_unused_clear): Likewise.
11866 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
11867 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
11868 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

11871 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
11872 vbitset_or_and_cmp, vbitset_copy): Likewise.
11873

11878 (ATTRIBUTE_UNUSED): Define unconditionally.
11879
11880 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
11881 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>

11885 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
11886 from libbitset.
11887
11888 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
11889 `How Can I Reset @code{yyparse}', since texinfo does not allow
11890 arbitrary @ in node names.
11891
11892 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
11893 shouldn't be needed according to the gettext 0.12.1 documentation
11894 but which seem to be needed anyway: codeset.m4 glibc21.m4
11895 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
11896 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
11897 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
11898
11899 * lib/.cvsignore: Add stdbool.h.
11900 * m4/.cvsignore: Add nls.m4, po.m4.
11901
11902 Upgrade to CVS gnulib.
11903 * stdbool_.h: File renamed from stdbool.h.in.
11904 * configure.ac (AM_STDBOOL_H): Invoke this instead of
11905 AC_HEADER_STDBOOL.
11906 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
11907 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
11908 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
11909 (MOSTLYCLEANFILES): New var.
11910 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
11911 (stdbool.h): New rule.
11912 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
11913 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
11914 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
11915 m4/quote.m4: Upgrade to today's gnulib.
11916
11917 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
11918 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
11919 the tests right now.
11920 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
11921 yyerror are declared before use; C99 requires this.
11922
119232003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11924
11925 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
11926 first.
11927 (yyrecoverSyntaxError): Correct the logic for setting and testing
11928 yyerrState.
11929 Correct comment on handling EOF.
11930 Allow states with only a default reduction, rather than failing
11931 (I can't quite reconstruct why these were not allowed before).
11932
11933 Fixes to avoid problem that $-N rules in GLR parsers can cause
11934 buffer overruns, corrupting state.
11935
11936 * src/output.c (prepare_rules): Output max_left_semantic_context
11937 definition.
11938 * src/reader.h (max_left_semantic_context): New variable declaration.
11939 * src/scan-gram.l (max_left_semantic_context): Define.
11940 (handle_action_dollar): Update max_left_semantic_context.
11941 * data/glr.c (YYMAXLEFT): New definition.
11942 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
11943 (yyresolveAction): Ditto.
11944
11945 Fixes to problems with location handling in GLR parsers reported by
11946 Frank Heckenbach (2003/06/05).
11947
11948 * data/glr.c (YYLTYPE): Make trivial if locations not used.
11949 (YYRHSLOC): Add parentheses, and define only if locations used.
11950 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
11951 locations not used.
11952 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
11953 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
11954
11955 * tests/cxx-type.at: Exercise location information; update tests
11956 to differentiate output with and without locations.
11957 Remove forward declarations of yylex and yyerror---caused errors
11958 because default YYLTYPE not yet defined.
11959 Change semantic actions to compute strings, rather than printing
11960 them directly (to test proper passing of semantics values). Change
11961 output to prefix notation and update test data and expected results.
11962 (yylex): Track locations.
11963 (stmtMerge): Return value rather than printing, and include arguments
11964 in value.
11965
119662003-06-03 Paul Eggert <eggert@twinsun.com>
11967
11968 Avoid warnings generated by GCC 2.95.4 when Bison is
11969 configured with --enable-gcc-warnings.
11970 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
11971 yy::]b4_parser_class_name[::translate_,
11972 yy::Stack::operator[] (unsigned),
11973 yy::Stack::operator[] (unsigned) const,
11974 yy::Slice::operator[] (unsigned),
11975 yy::Slice::operator[] (unsigned) const):
11976 Rename local vars to avoid warnings.
11977 * tests/glr-regression.at (Improper handling of embedded actions
11978 and $-N in GLR parsers): Remove unused local variable from yylex.
11979 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11980 (void) as arg when not pure, since we now assume C89 when building
11981 Bison. Pacify GCC by using parameter.
11982
119832003-06-02 Paul Eggert <eggert@twinsun.com>
11984
11985 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11986 yy::Location::lines, yy::Location::columns): Rename arguments
11987 to avoid shadowing; this removes a warning generated by GCC 3.3.
11988
119892003-06-01 Paul Eggert <eggert@twinsun.com>
11990
11991 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11992 to g++, as GCC 3.3 complains if you do it.
11993 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11994 everything that WARNING_CFLAGS has, except omit warnings
11995 not suitable for C++.
11996 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11997 * tests/atlocal.in (CXXFLAGS): New var.
11998 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11999
12000 Fix a GLR parser bug I reported in February; see
12001 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
12002 The problem was that GLR parsers did not conform to the C standard,
12003 because actions like { $1 = $2 + $3; } expanded to expressions
12004 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12005 to a local variable. The C standard says that expressions
12006 like (var = f ()) + (var = f ()) have undefined behavior.
12007 Another problem was that GCC sometimes issues warnings that
12008 yyfill and its parameters are unused.
12009
12010 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12011 as possibly unused.
12012 (yyfill): New function.
12013 (YYFILL): Use it.
12014 (yyuserAction): Change type of yynormal to bool, so that it matches
12015 the new yyfill signature. Mark it as possibly unused.
12016
12017
12018 Follow up on a bug I reported in February, where a Bison-generated
12019 parser can loop. Provide a test case and a fix for yacc.c. I
12020 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12021 The original bug report is in:
12022 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
12023
12024 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12025 macro's size was becoming unwieldy.
12026 (yyerrlab): Do not discard an empty lookahead symbol, as this
12027 might destroy garbage.
12028 (yyerrorlab): New label, with the old contents of YYERROR,
12029 plus the following change: pop the stack of rhs corresponding
12030 to the production that invoked YYERROR. That is how Yacc
12031 behaves, and POSIX requires this behavior.
12032 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12033 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12034 Define 'alarm' to do nothing if unistd.h is not available.
12035 Add a new rule "exp: '-' error;" to test the above change to
12036 data/yacc.c. Use 'alarm' to abort any test taking longer than
12037 10 seconds, as it's probably looping.
12038 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12039 Also, the new yacc.c generates two fewer diagnostics for an
12040 existing test.
12041
120422003-05-24 Paul Eggert <eggert@twinsun.com>
12043
12044 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
12045 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
12046 This fixes a problem reported by John Bowman when the Compaq/HP
12047 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
12048 -ansi -Wall -gall).
12049 * data/yacc.c (union yyalloc): Likewise.
12050 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
12051
12052 Switch from 'int' to 'bool' where that makes sense.

12057 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
12058 Return or accept bool, not int. All callers changed.

12068 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
12069 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
12070 bitset_stats_or_and_cmp): Likewise.
12071 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
12072 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
12073 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
12074 ebitset_xor_cmp): Likewise.
12075 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
12076 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
12077 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
12078 lbitset_xor_cmp): Likewise.
12079 * lib/bbitset.h: Include <stdbool.h>.
12080 (struct bitset_vtable): The following members now return bool, not
12081 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
12082 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
12083 or_and_cmp).
12084 * src/conflicts.c (count_rr_conflicts): Likewise.
12085 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
12086 All uses changed.
12087 * lib/ebitset.c (ebitset_obstack_init): Likewise.
12088 * lib/lbitset.c (lbitset_obstack_init): Likewise.
12089 * src/getargs.c (debug_flag, defines_flag, locations_flag,

12093 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
12094 graph_flag): Likewise.

12100 (long_options, getargs): Use it.
12101 * src/lalr.c (build_relations): Use bool, not int.
12102 * src/nullable.c (nullable_compute): Likewise.
12103 * src/print.c (print_reductions): Likewise.

12106 * src/output.c (prepare): Use it.
12107 * src/output.c (token_definitions_output,
12108 symbol_destructors_output, symbol_destructors_output): Use string,
12109 not boolean integer, to keep track of whether to output separator.

12114
121152003-05-14 Paul Eggert <eggert@twinsun.com>
12116
12117 * src/parse-gram.y (rules_or_grammar_declaration): Require a
12118 semicolon after a grammar declaration, in the interest of possible
12119 future changes to the Bison input language.
12120 Do not allow a stray semicolon at the start of the grammar.
12121 (rhses.1): Allow one or more semicolons after any rule, including
12122 just before "|" as required by POSIX.
12123 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
12124 grammar.
12125
121262003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
12127
12128 %parse-param support for lalr1.cc.
12129
12130 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
12131 b4_cc_constructor_calls, b4_cc_constructor_call,
12132 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
12133 definitions.
12134 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
12135 parse-param arguments.
12136 (yy::b4_parser_class_name): Declare instance variables to
12137 hold parse-param arguments.
12138 * tests/calc.at: s/value/semantic_value/ because value clashes
12139 with a member of yy::b4_parser_class_name. Adjust C++ code
12140 to handle %parse-param. Enable %parse-param test in C++.
12141
121422003-05-12 Paul Eggert <eggert@twinsun.com>
12143
12144 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
12145 English a bit. Fix fclose typo. Change "const char" to "char
12146 const", and use ANSI C rather than K&R for "main". Suggest
12147 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
12148 and suggest yy_switch_to_buffer.
12149
121502003-05-05 Paul Eggert <eggert@twinsun.com>
12151
12152 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
12153 C89. This avoids a diagnostic on compilers that define __STDC__
12154 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
12155 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12156
121572003-05-03 Paul Eggert <eggert@twinsun.com>
12158
12159 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
12160 Do not overrun array bounds.
12161 This should fix a bug reported today by Olatunji Oluwabukunmi in
12162 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
12163
121642003-04-29 Akim Demaille <akim@epita.fr>
12165
12166 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
12167 * src/getargs.c, src/getargs.h: here, as bool, not int.
12168 (nondeterministic_parser): New.
12169 * src/parse-gram.y, src/scan-gram.l: Support
12170 %nondeterministic-parser.
12171 * src/output.c (prepare): Use nondeterministic_parser instead
12172 of glr_parser where appropriate.
12173 * src/tables.c (conflict_row, action_row, save_row)
12174 (token_actions, token_actions, pack_vector): Ditto.
12175
121762003-04-29 Akim Demaille <akim@epita.fr>
12177
12178 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
12179
121802003-04-29 Akim Demaille <akim@epita.fr>
12181
12182 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
12183 with %pure-parser and %locations to exercise the patch from Yakov
12184 Markovitch below.
12185
121862003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
12187
12188 * data/yacc.c: (b4_lex_param): Corrected for the case where
12189 %lex-param is provided and %pure-parser isn't.
12190
121912003-04-27 Paul Eggert <eggert@twinsun.com>
12192
12193 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
12194 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
12195 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
12196 if it is not defined.
12197 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
12198
121992003-04-26 Paul Eggert <eggert@twinsun.com>
12200
12201 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
12202 Declare to be of type suitable for the ninf value itself, not of
12203 type suitable for the corresponding table, since the latter might
12204 be unsigned but the ninf value might be negative. This fixes a
12205 bug reported by Alexandre Duret-Lutz in
12206 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
12207
12208 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
12209 invokes it. We shouldn't invoke it twice because it will attempt
12210 to put error.o in the archive twice. This fixes a glitch reported
12211 by Martin Mokrejs in
12212 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12213
122142003-04-21 Paul Eggert <eggert@twinsun.com>
12215
12216 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
12217 to gnulib.
12218
122192003-04-21 Yakov Markovitch <Markovitch@iso.ru>
12220
12221 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
12222 Fix obvious typo that results in uncompilable GLR parsers
12223 when both %pure-parser and %locations are used. (trivial change)
12224
122252003-04-17 Paul Eggert <eggert@twinsun.com>
12226
12227 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
12228 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
12229 Do not insert the expected token via unput, as this runs afoul
12230 of a POSIX-compatibility bug in flex 2.5.31.
12231 All uses changed to BEGIN the parent state,
12232 since we no longer insert the expected token via unput.
12233 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
12234 that is no longer emitted after the above change.
12235
12236 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
12237 the first one. This change is from Paul Hilfinger, and it fixes
12238 regression reported by Werner Lemberg in
12239 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
12240
12241 (resolve_sr_conflict): Don't invoke state_errs_set
12242 unless one or more tokens have been explicitly made errors.
12243 Otherwise, the above change causes Bison to abort.
12244
12245 * tests/existing.at (GNU pic Grammar): New test case, taken from
12246 Lemberg's email.
12247
122482003-03-31 Akim Demaille <akim@epita.fr>
12249
12250 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
12251
122522003-03-31 Akim Demaille <akim@epita.fr>
12253
12254 * src/output.c (prepare_symbols): Avoid trailing spaces in the
12255 output.
12256
122572003-03-31 Akim Demaille <akim@epita.fr>
12258
12259 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
12260 From Paul Hilfinger.
12261
122622003-03-29 Akim Demaille <akim@epita.fr>
12263
12264 * m4/error.m4: Do not put under dynamic conditions some code which
12265 expansion is under static control.
12266
122672003-03-29 Akim Demaille <akim@epita.fr>
12268
12269 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
12270
122712003-03-29 Akim Demaille <akim@epita.fr>
12272
12273 * doc/bison.texinfo (Strings are Destroyed): New.
12274
122752003-03-13 Paul Eggert <eggert@twinsun.com>
12276
12277 * .cvsignore: Add configure.lineno.
12278 * src/.cvsignore: Add yacc.
12279 * tests/.cvsignore: Add testsuite.log.
12280 * doc/fdl.texi: Sync with latest FSF version.
12281
122822003-03-12 Paul Eggert <eggert@twinsun.com>
12283
12284 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
12285 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
12286 cursor, instead of leaving it undefined. This fixes a bug
12287 reported by Tim Van Holder in
12288 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
12289 * tests/input.at (Torturing the Scanner): Test the scanner on
12290 an empty input file, which was Tim Van Holder's test case.
12291
12292 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
12293 <sys/resource.h> can be included, include sys/time.h and
12294 sys/times.h first, if available. This works around the SunOS
12295 4.1.4 porting bug reported by Bruce Becker in
12296 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
12297
12298 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
12299 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
12300 AC_HEADER_SYS_WAIT.
12301
12302 Merge changes from gnulib. This was prompted because the CVS
12303 snapshot didn't build on Solaris 7 due to strnlen problems.
12304
12305 These changes need to be merged back into gnulib:
12306 * lib/hash.c: Include <stdbool.h> unconditionally.
12307 * m4/onceonly.m4 (m4_quote): New macro.
12308 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
12309 Quote AC_FOREACH variable-expansions properly.
12310 The 2003-01-03 obstack.h change also needs merging.
12311 {end of changes requiring merging}
12312
12313 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
12314 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
12315 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
12316 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
12317 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
12318 New files, imported from gnulib.
12319 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
12320 above.
12321
12322 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
12323 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
12324 gnulib sources.
12325
12326 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
12327 Add.
12328 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
12329 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
12330 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
12331 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
12332 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
12333 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
12334 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
12335 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
12336 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
12337 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
12338 (jm_PREREQ_ARGMATCH): Remove.
12339 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
12340 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
12341
12342 * src/system.h: Include <stdbool.h> unconditionally.
12343
12344 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
12345 assuming at least C89 in the bitset code for some time now.
12346
123472003-03-03 Akim Demaille <akim@epita.fr>
12348
12349 * ro.po: New.
12350
123512003-03-02 Akim Demaille <akim@epita.fr>
12352
12353 * doc/bison.texinfo (Table of Symbols): Reactivate the
12354 documentation for %lex-param, and %parse-param.
12355
123562003-03-02 Akim Demaille <akim@epita.fr>
12357
12358 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
12359 generate verbose error messages.
12360 Use the number of tokens as an upper bound in yytname, as it
12361 cannot be a non terminal.
12362
123632003-03-02 Akim Demaille <akim@epita.fr>
12364
12365 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
12366 message.
12367
123682003-03-02 Akim Demaille <akim@epita.fr>
12369
12370 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
12371 Use them to exercise yycheck overrun.
12372 Based on Andrew Suffield's grammar.
12373
123742003-03-02 Akim Demaille <akim@epita.fr>
12375
12376 Create tests/local.at for Bison generic testing macros.
12377
12378 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
12379 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
12380 This new file.
12381 * tests/calc.at (AT_CHECK_CALC): Adjust.
12382 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
12383 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
12384 * tests/local.at: here.
12385 (AT_COMPILE_CXX): Tags the tests using it as c++.
12386 Ignore the test if CXX is not functional.
12387
123882003-03-01 Paul Eggert <eggert@twinsun.com>
12389
12390 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12391 not loc->end, since loc->end might contain garbage and this leads
12392 to undefined behavior on some platforms.
12393 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12394 depend on *loc, so that the reader doesn't give the the false
12395 impression that *loc is initialized.
12396 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12397 does not survive the return.
12398
123992003-03-01 Akim Demaille <akim@epita.fr>
12400
12401 * src/scan-gram.l (code_start): Always initialize it when entering
12402 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12403 yylex invocation. An alternative would be making it static, but
12404 then it starts with the second %%'s beginning, instead of its end.
12405
124062003-02-28 Paul Eggert <eggert@twinsun.com>
12407
12408 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12409 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12410 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12411
124122003-02-26 Paul Eggert <eggert@twinsun.com>
12413
12414 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12415 Remove Sequent/Pyramid discussion (nobody uses them any more).
12416 Merge VMS and MS-DOS discussion; these ports may well be dead
12417 but let's keep mentioning them for now. Put <> around email
12418 addresses. Add copyright notice.
12419
124202003-02-24 Paul Eggert <eggert@twinsun.com>
12421
12422 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12423 to avoid collision with flex use of yylineno.
12424 Problem reported by Bruce Lilly in
12425 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
12426 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
12427 * data/yacc.c (yy_reduce_print): Likewise.
12428
12429 * config/depcomp: Sync with Automake 1.7.3.
12430
124312003-02-21 Akim Demaille <akim@epita.fr>
12432
12433 * data/lalr1.cc: Use temporary variables instead of casts to
12434 change integer types.
12435 Suggested by Paul Eggert.
12436
124372003-02-21 Akim Demaille <akim@epita.fr>
12438
12439 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12440 to avoid confusions with lalr1.cc's notion of Position.
12441 Suggested by Paul Eggert.
12442
124432003-02-20 Akim Demaille <akim@epita.fr>
12444
12445 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12446 before initial_columns.
12447 (location.hh): Use consistent variable names when defining the
12448 operator<<.
12449 Use "last" so that we subtract from Positions, not from unsigned.
12450
124512003-02-20 Akim Demaille <akim@epita.fr>
12452
12453 * data/lalr1.cc (position.hh): New subfile, including the extended
12454 and Doxygen'ed documentation of class Position.
12455 (location.hh): Use it.
12456 Document a` la Doxygen.
12457 With the help of Benoit Perrot.
12458
124592003-02-20 Akim Demaille <akim@epita.fr>
12460
12461 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
12462 AT_YACC_IF.
12463 Redefine AT_YYERROR_SEES_LOC_IF using it.
12464 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
12465 not defined.
12466 Don't use the location in yy::Parser::error_ and
12467 yy::Parser::print_ when not %locations.
12468 Activate more lalr1.cc tests.
12469
124702003-02-19 Akim Demaille <akim@epita.fr>
12471
12472 * data/lalr1.cc: When displaying a line number, be sure to make it
12473 an int.
12474
124752003-02-19 Akim Demaille <akim@epita.fr>
12476
12477 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12478 Remove, useless.
12479 (YYABORT, YYACCEPT, YYERROR): New.
12480 * tests/calc.at: Renable the lalr1.cc test.
12481
124822003-02-19 Akim Demaille <akim@epita.fr>
12483
12484 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12485 error recovery, mixing with/without pops and discarding of the
12486 lookahead.
12487 Exercise YYERROR.
12488 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
12489
124902003-02-17 Paul Eggert <eggert@twinsun.com>
12491
12492 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
12493 * tests/testsuite.at (AT_COMPILE): Use them.
12494 This fixes the testsuite problem reported by Robert Lentz in
12495 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
12496
124972003-02-12 Paul Eggert <eggert@twinsun.com>
12498
12499 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
12500 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
12501 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
12502 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12503 Check for malloc failure, for consistency with yacc.c.
12504 (yytname_size): Remove, for consistency with yacc.c.
12505
12506 The bug still remains in data/lalr1.cc, as I didn't have time
12507 to fix it there.
12508
125092003-02-06 Akim Demaille <akim@epita.fr>
12510
12511 * configure.ac (GXX): Rename as...
12512 (CXX): this, to keep the original Autoconf semantics.
12513 Require 2.57.
12514 * data/lalr1.cc: Fix b4_copyright invocations.
12515 If YYDEBUG is not defined, don't depend upon name_ being defined.
12516 (location.hh): Include string and iostream.
12517 (Position::filename): New member.
12518 (Position::Position ()): New.
12519 (operator<< (Position)): New.
12520 (operator- (Position, int)): New.
12521 (Location::first, Location::last): Rename as...
12522 (Location::begin, Location::end): these, to mock the conventional
12523 iterator names.
12524 (operator<< (Location)): New.
12525 * tests/atlocal.in (CXX): New.
12526 * tests/testsuite.at (AT_COMPILE_CXX): New.
12527 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
12528 locations in a more synthetic way.
12529 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
12530 lalr1.cc is used.
12531 Adjust the C locations to match those from Emacs: first column is
12532 column 0.
12533 Change all the expected results.
12534 Conform to the GCS: simplify the locations when applicable.
12535 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
12536 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
12537 these CPP macros with the m4 macros new defined by...
12538 (AT_CHECK_PUSHDEFS): this, i.e.:
12539 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
12540 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)

12544 Use it for the first lalr1.cc test.
12545
125462003-02-04 Akim Demaille <akim@epita.fr>
12547
12548 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
12549 Location as is defined.
12550
125512003-02-04 Akim Demaille <akim@epita.fr>
12552
12553 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
12554 name_ being defined.
12555
125562003-02-03 Paul Eggert <eggert@twinsun.com>
12557
12558 * src/gram.h (start_symbol): Remove unused decl.
12559
12560 Use more-consistent naming conventions for local vars.
12561
12562 * src/derives.c (derives_compute): Change type of local var from
12563 int to rule_number.
12564 * src/gram.c (grammar_rules_partial_print): Likewise.
12565 * src/print.c (print_core): Likewise.
12566 * src/reduce.c (reduce_grammar_tables): Likewise.
12567
12568 * src/gram.c (grammar_dump): Change name of item_number *
12569 local var from r to rp.
12570 * src/nullable.c (nullable_compute): Likewise.
12571
12572 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
12573
12574 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
12575 for symbol or symbol_number var.
12576 * src/reader.c (grammar_start_symbol_set): Likewise.
12577 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
12578 Likewise.
12579 * src/state.c (transitions_to): Likewise.
12580 * src/state.h: Likewise.
12581 * src/tables.c (symbol_number_to_vector_number): Likewise.
12582
12583 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
12584 char * var.
12585
12586 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
12587 var.
12588
12589 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
12590 var.
12591
12592 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
12593 Use str, not s, for char * var. Use ch, not c, for character var.
12594 Use size for size var.
12595
12596 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
12597 char * var.
12598 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
12599 uniqstr var.
12600 * src/uniqstr.h: Likewise.

12602 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12603 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12604 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
12605 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
12606 param to have same name as that of enum, so that we don't use
12607 "s" to stand for a non-state.
12608
126092003-02-02 Akim Demaille <akim@epita.fr>
12610
12611 * src/scan-skel.l: Scan more than one inert character per yylex
12612 invocation.
12613
126142003-02-01 Paul Eggert <eggert@twinsun.com>
12615
12616 Version 1.875a.
12617
12618 * po/LINGUAS: Add ms.
12619
126202003-01-30 Akim Demaille <akim@epita.fr>
12621
12622 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
12623
126242003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12625
12626 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
12627 of $1.
12628
12629 Changes in response to error report by S. Eken: GLR mode does not
12630 handle negative $ indices or $ indices in embedded rules correctly.
12631 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
12632
12633 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
12634 (b4_rhs_location): Ditto.
12635 (yyfill): New function to copy from stack tree into array
12636 incrementally.
12637 (yyuserAction): Modify to allow incremental move of semantic values
12638 to rhs array when in GLR mode.
12639 Define YYFILL to use in user-defined actions to fill semantic array
12640 as needed.
12641 Remove dummy use of yystack, as there is now a guaranteed use.
12642 (yydoAction): Modify to allow incremental move of semantic values
12643 to rhs array when in GLR mode.
12644 (yyresolveAction): Ditto.
12645 (yyglrShiftDefer): Update comment.
12646 (yyresolveStates): Use X == NULL for pointers, not !X.
12647 (yyglrReduce): Ditto.
12648 (yydoAction): Ditto
12649
12650 * tests/glr-regr1.at: Rename to ...
12651 * tests/glr-regression.at: Add new regression test for the problems
12652 described above (adapted from S. Eken).
12653 Update copyright notice.
12654 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
12655 * tests/Makefile.am: Ditto.
12656
126572003-01-28 Paul Eggert <eggert@twinsun.com>
12658
12659 * data/lalr1.cc: Do not use @output_header_name@ unless
12660 b4_defines_flag is set. This fixes two bugs reported by
12661 Tim Van Holder in
12662 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
12663 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
12664
126652003-01-21 Paul Eggert <eggert@twinsun.com>
12666
12667 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
12668 we don't need to worry about yyerrlab1 being reported as an
12669 "unused label" by non-GCC C compilers. The downside is that if
12670 locations are used then a couple of statements are duplicated each
12671 time YYERROR is invoked, but the upside is that the warnings
12672 should vanish.
12673 (yyerrlab1): Move code to YERROR.
12674 (yyerrlab2): Remove. Change uses back to yyerrlab1.
12675 This reverts some of the 2002-12-27 change.
12676
126772003-01-17 Paul Eggert <eggert@twinsun.com>
12678
12679 * src/output.c (symbol_printers_output): Fix typo that led
12680 to core dump. Problem reported by Antonio Rus in
12681 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
12682
126832003-01-13 Akim Demaille <akim@epita.fr>,
12684 Quoc Peyrot <chojin@lrde.epita.fr>,
12685 Robert Anisko <anisko_r@lrde.epita.fr>
12686
12687 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
12688 when the stacks contain one element, as the loop would otherwise
12689 free the last state, and then use the top state (the one we just
12690 popped). This means that the initial elements will not be freed
12691 explicitly, as is the case in yacc.c; it is not a problem, as
12692 these elements have fake values.
12693
126942003-01-11 Paul Eggert <eggert@twinsun.com>
12695
12696 * NEWS: %expect-violations are now just warnings, reverting
12697 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
12698 bootstrapping problem reported by Matthias Klose; see
12699 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
12700 * src/conflicts.c (conflicts_print): Likewise.
12701 * tests/conflicts.at (%expect not enough, %expect too much,
12702 %expect with reduce conflicts): Likewise.
12703 * doc/bison.texinfo (Expect Decl): Document this. Also mention
12704 that the warning is enabled if the number of conflicts changes
12705 (not necessarily increases).
12706
12707 * src/getargs.c (version): Update copyright year.
12708
127092003-01-09 Akim Demaille <akim@epita.fr>
12710
12711 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
12712
127132003-01-08 Paul Eggert <eggert@twinsun.com>
12714
12715 * Makefile.maint (WGETFLAGS):
12716 New macro, containing "-C off" to disable proxy caches.
12717 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
12718 (rel-check): Use $(WGET) instead of wget.
12719
127202003-01-06 Paul Eggert <eggert@twinsun.com>
12721
12722 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
12723 the GLR paper of Scott, Johnstone and Hussain.
12724
127252003-01-04 Paul Eggert <eggert@twinsun.com>
12726
12727 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
12728 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
12729 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
12730 (EXTRA_LIBRARIES): New var, for liby.a.
12731 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
12732 (EXTRA_SCRIPTS): New var, for yacc.
12733
12734 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
12735 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
12736 Problem reported by Nelson H. F. Beebe.
12737
127382003-01-03 Paul Eggert <eggert@twinsun.com>
12739
12740 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
12741 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
12742 when compiling Bison 1.875's `bitset bset = obstack_alloc
12743 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
12744
12745 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
12746 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
12747 grow to a huge size with typical invocation.
12748
12749 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
12750 Use the pattern recommended by Autoconf 2.57, except also protect
12751 against double-definition.
12752 * src/system.h: Likewise.
12753 Portability issues reported by Nelson H. F. Beebe.
12754
12755 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
12756 All uses changed. Provide a definition in both C and C++.
12757 (yytrue, yyfalse): Define even if defined (__cplusplus).
12758
12759 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
12760 Reported by Nelson H. F. Beebe.
12761
12762 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
12763
127642003-01-02 Paul Eggert <eggert@twinsun.com>
12765
12766 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
12767 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
12768 Bug reported by Nelson H. F. Beebe.
12769
127702003-01-01 Paul Eggert <eggert@twinsun.com>
12771
12772 * Version 1.875.
12773
127742002-12-30 Paul Eggert <eggert@twinsun.com>
12775
12776 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
12777 Moved here from...
12778 (<INITIAL>","): Here. This causes stray "," to be treated
12779 more uniformly.
12780
12781 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
12782 last brace in braced code when not in Yacc mode, for compatibility
12783 with Bison 1.35. This resurrects the 2001-12-15 patch to
12784 src/reader.c.
12785
12786 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
12787 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
12788
127892002-12-28 Paul Eggert <eggert@twinsun.com>
12790
12791 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
12792 that of SYM's type. This fixes Debian bug 168069, reported by
12793 Thomas Olsson.
12794
127952002-12-28 Paul Eggert <eggert@twinsun.com>
12796
12797 Version 1.75f.
12798
12799 Switch back to the Yacc style of conflict reports, undoing some
12800 of the 2002-07-30 change.
12801 * doc/bison.texinfo (Understanding): Use Yacc style for
12802 conflict reports. Also, use new way of locating rules.
12803 * src/conflicts.c (conflict_report):
12804 Renamed from conflict_report_yacc, removing the old
12805 'conflict_report'. Translate the entire conflict report at once,
12806 so that we don't assume that "," has the same interpretation in
12807 all languages.
12808 (conflicts_output): Use Yacc-style conflict report for each state,
12809 instead of our more-complicated style.
12810 (conflicts_print): Use Yacc-style conflict report, except print
12811 the input file name when not emulating Yacc.
12812 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
12813 Conflicted Reduction, %expect not enough, %expect too much,
12814 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
12815 * tests/existing.at (GNU Cim Grammar): Likewise.
12816 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
12817
12818 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
12819 fatal): Don't invoke fflush; it's not needed and it might even be
12820 harmful for stdout, as stdout might not be open.
12821 * src/reduce.c (reduce_print): Likewise.
12822
128232002-12-27 Paul Eggert <eggert@twinsun.com>
12824
12825 Fix a bug where error locations were not being recorded correctly.
12826 This problem was originally reported by Paul Hilfinger in
12827 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
12828
12829 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12830 top of the location stack's error locations.
12831 (yyerrlab): Set it. When discarding a token, push its location
12832 onto yylerrsp so that we don't lose track of the error's end.
12833 (yyerrlab1): Now is only the target of YYERROR, so that we can
12834 properly record the location of the action that failed. For GCC
12835 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12836 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12837 (yyerrlab2): New label, which yyerrlab now falls through to.
12838 Compute the error's location by applying YYLLOC_DEFAULT to
12839 the locations of all the symbols that went into the error.
12840 * doc/bison.texinfo (Location Default Action): Mention that
12841 YYLLOC_DEFAULT is also invoked for syntax errors.
12842 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12843 Error locations include the locations of all the tokens that were
12844 discarded, not just the last token.
12845
128462002-12-26 Paul Eggert <eggert@twinsun.com>
12847
12848 * src/files.c: Include quote.h.
12849 (compute_output_file_names): Warn if we detect conflicting
12850 outputs to the same file. This should catch the misunderstanding
12851 exemplified by Debian Bug 165349, reported by Bruce Stephens..
12852
12853 * src/conflicts.c (conflicts_print): If the user specifies
12854 "%expect N", report an error if there are any reduce/reduce
12855 conflicts. This is what the manual says should happen.
12856 This fixes Debian bug 130890, reported by Anthony DeRobertis.
12857 * tests/conflicts.at (%expect with reduce conflicts): New test.
12858
12859 Don't use m4_include on relative file names, as it doesn't work as
12860 desired if there happens to be a file with that name under ".".
12861
12862 * m4sugar/version.m4: Remove; it was included but it wasn't used.
12863 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
12864 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
12865 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
12866 * src/output.c (output_skeleton): Use full path names when
12867 specifying a file to include; don't rely on include path, as
12868 it's unreliable when the working file contains a file with
12869 that name.
12870
128712002-12-25 Paul Eggert <eggert@twinsun.com>
12872
12873 Remove obsolete references to bison.simple and bison.hairy.
12874 Problem mentioned by Aubin Mahe in
12875 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
12876 * data/glr.c: Comment fix.
12877 * doc/bison.1: Remove references. Also, mention "yacc".
12878
12879 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
12880 with -g option.
12881
12882 * src/parse-gram.y (declaration): Use enum "report_states" rather
12883 than its numeric value 1.
12884
12885 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
12886 opening a new one. This fixes Debian bug 165349, reported by
12887 Bruce Stephens.
12888
128892002-12-24 Paul Eggert <eggert@twinsun.com>
12890
12891 Version 1.75e.
12892
12893 * Makefile.maint (cvs-update): Don't assume that the shell
12894 supports $(...), as Solaris sh doesn't.
12895
12896 * src/parse-gram.y (lloc_default): Remove test for empty
12897 nonterminals at the end, since it didn't change the result.
12898
128992002-12-24 Paul Eggert <eggert@twinsun.com>
12900
12901 If the user does not define YYSTYPE as a macro, Bison now declares it
12902 using typedef instead of defining it as a macro. POSIX requires this.
12903 For consistency, YYLTYPE is also declared instead of defined.
12904
12905 %union directives can now have a tag before the `{', e.g., the
12906 directive `%union foo {...}' now generates the C code
12907 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12908 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12909 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12910 instead of `yyltype'.
12911
12912 `yystype' and `yyltype' are now obsolescent macros instead of being
12913 typedefs or tags; they are no longer documented and will be
12914 withdrawn in a future release.
12915
12916 * data/glr.c (b4_location_type): Remove.
12917 (YYSTYPE): Renamed from yystype.
12918 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
12919 (struct YYLTYPE): Renamed from struct yyltype.
12920 (YYLTYPE): Renamed from yyltype.
12921 (yyltype, yystype): New (and obsolescent) macros,

12923 * data/yacc.c: Likewise.
12924
12925 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12926 does not specify a union tag. This is for compatibility with
12927 Solaris 9 yacc.
12928
12929 * src/parse-gram.y (add_param): 2nd arg is now char * not char
12930 const *, since it is now modified by stripping surrounding { }.
12931 (current_braced_code): Remove.
12932 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
12933 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
12934 trailing " {...}". Now of type <chars>.
12935 (grammar_declaration): Adjust to bundled tokens.

12939
12940 * src/reader.h (braced_code, current_braced_code): Remove.

12945 (SC_PRE_CODE): New state, for scanning after a keyword that
12946 has (or usually has) an immediately-following braced code.
12947 (token_type): New local var, to keep track of which token type
12948 to return when scanning braced code.
12949 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
12950 <INITIAL>"%parse-param", <INITIAL>"%printer",
12951 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
12952 instead of returning a token type immediately.
12953 (<INITIAL>"{"): Set token type.
12954 (<SC_BRACED_CODE>"}"): Use it.
12955 (handle_action_dollar, handle_action_at): Now returns bool
12956 indicating success. Fail if ! current_rule; this prevents a core dump.
12957 (handle_symbol_code_dollar, handle_symbol_code_at):
12958 Remove; merge body into caller.
12959 (handle_dollar, handle_at): Complain in invalid contexts.

12971
12972 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
12973 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
12974 lookahead symbol, and which sets yychar in parser actions) and it
12975 disagreed with the Bison documentation. Bug
12976 reported by Andrew Walrond.
12977
12978 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12979 as the caller now does that.
12980 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12981 (YYEMPTY): Parenthesize right hand side, since others use it.
12982 (yyparse): Don't assume that our generated code is the only code
12983 that sets yychar.
12984
129852002-12-13 Paul Eggert <eggert@twinsun.com>
12986

12997
12998 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around

13015
130162002-12-12 Paul Eggert <eggert@twinsun.com>
13017
13018 Remove unportable casts and storage allocation tricks.
13019 While we're at it, remove almost all casts, since they
13020 usually aren't needed and are a sign of trouble.
13021
13022 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13023
13024 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13025 the pointer DSET returned by malloc; this isn't portable.
13026 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13027 Similarly for DERIVES.
13028 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
13029 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.

13031
13032 * src/derives.c (derives_compute): Do not bother invoking
13033 int_of_rule_number, since rule numbers are integers.
13034
13035 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
13036 rather than XMALLOC (char, N).

13039
13040 * src/gram.h (symbol_number_as_item_number,
13041 item_number_as_symbol_number, rule_number_as_item_number,
13042 item_number_as_rule_number):
13043 Now inline functions rather than macros, to avoid casts.
13044 * src/state.h (state_number_as_int): Likewise.
13045 * src/tables.c (state_number_to_vector_number,
13046 symbol_number_to_vector_number): Likewise.

13048 * src/gram.h (int_of_rule_number): Remove; no longer used.
13049
13050 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
13051 since the resulting storage is always stored into.
13052
13053 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
13054 where it's needed.
13055
13056 * src/muscle_tab.c (muscle_m4_output):
13057 Now inline. Return bool, not int.

13063 * src/uniqstr.c (uniqstr_print): Likewise.
13064 * src/muscle_tab.c (muscle_m4_output_processor):

13067 * src/symtab.c (symbol_check_defined_processor,
13068 symbol_check_alias_consistency_processor, symbol_pack_processor,
13069 symbol_translation_processor, hash_symbol_comparator,
13070 hash_symbol_hasher): Likewise.
13071 * src/uniqstr.c (uniqstr_print_processor): Likewise.
13072 * src/muscle_tab.c (muscles_m4_output):
13073 Use new functions instead of casting old functions unportably.

13076 symbols_token_translations_init):
13077 Likewise.
13078 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
13079
13080 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13081 var instead of casting to long, to avoid casts.
13082 (prepare_states): Use MALLOC rather than alloca, so that we don't
13083 have to worry about alloca.
13084 * src/state.c (state_hash_lookup): Likewise.
13085
13086 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
13087 local var instead of casting to unsigned char, to avoid casts.
13088
13089 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
13090 STATE_ALLOC): Remove.
13091 (transitions_new, errs_new, reductions_new, state_new): Use malloc
13092 rather than calloc, and use offsetof to avoid allocating slightly
13093 too much storage.
13094 (state_new): Initialize all members.
13095
13096 * src/state.c (state_hash): Use unsigned accumulator, not signed.
13097
13098 * src/symtab.c (symbol_free): Remove; unused.
13099 (symbol_get): Remove cast in lhs of assignment.
13100 (symbols_do): Now static. Accept generic arguments, not
13101 hashing-related ones.
13102
13103 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
13104 (symbol_processor): Remove.
13105 (symbols_do): Remove decl; now static.

13109 (<inttypes.>, <stdint.h>): Include if available.
13110 (uintptr_t): New type, if system lacks it.
13111 (CALLOC, MALLOC, REALLOC): New macros.
13112 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
13113 new macros.

13118 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
13119 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
13120
13121 * src/vcg.h: Correct misspellings.
13122
13123 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
13124
13125
13126 * src/getargs.c (getargs): Don't assume EOF == -1.
13127
131282002-12-09 Paul Eggert <eggert@twinsun.com>
13129
13130 Change identifier spellings to avoid collisions with names
13131 that are reserved by POSIX.
13132
13133 Don't use names ending in _t, since POSIX reserves them.
13134 For consistency, remove _e and _s endings -- they're weren't
13135 needed to remove ambiguity. All uses changed.
13136 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
13137 turn was just renamed from struniq_t.
13138 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
13139 which in turn was just renamed from struniq_processor_t.
13140 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

13211 value_t_as_yystype -> value_as_yystype.
13212
13213 Don't include <errno.h> in the mainstream code, since it
13214 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
13215 * lib/get-errno.c, lib/get-errno.h: New files.
13216 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

13226 (TAB_EXT): Renamed from EXT_TAB.
13227 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
13228
13229 Avoid str[a-z]*, since <string.h> reserves that name space.
13230 Change all instances of "struniq" in names to "uniqstr", and
13231 likewise for "STRUNIQ" and "UNIQSTR".
13232 * src/uniqstr.c: Renamed from src/struniq.c.
13233 * src/uniqstr.h: Renamed from src/struniq.h.

13245 (N_EXPAND): Renamed from N_STRETCH.
13246
13247 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.

13249 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
13250 Remove; unused.

13253 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.

13264 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
13265 G_NODE_ALIGNEMENT.
13266
13267
13268 * lib/timevar.c (timevar_report): Renamed from time_report,
13269 for consistency with other names.
13270 * lib/timevar.h (timevar_report): New decl.
13271 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
13272
13273
13274 Sort include-file uses.
13275
13276 Reorder all include files under src to be in the order "system.h".
13277 then the ../lib include files in angle brackets (alphabetized),
13278 then the . include files in double-quotes (alphabetized). Fix
13279 dependency breakages encountered in this process, as follows:
13280 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
13281 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
13282 * src/state.h: Include "symtab.h".
13283
132842002-12-08 Paul Eggert <eggert@twinsun.com>
13285
13286 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
13287 since this causes problems when __file__ contains character
13288 sequences like "@" that are treated specially by src/scan-skel.l.
13289 Instead, just use the file's basename. This fixes the bug
13290 reported by Martin Mokrejs in
13291 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
13292

13294
13295 Add support for rules that do not have trailing semicolons, as

13300 (empty_location): Now const.
13301 (location_print): New function. Follow the recommendation of the

13303 * src/location.h: Do not include <quotearg.h>; no longer needed.
13304 (boundary): New type.
13305 (location_t): Use it. This allows locations to span file boundaries.
13306 All member uses changed: file -> start.file or end.file (as needed),
13307 first_line -> start.line, first_column -> start.column,
13308 last_line -> end.line, last_column -> end.column.
13309 (equal_boundaries): New function.
13310 (LOCATION_RESET, LOCATION_STEP): Remove.
13311 (LOCATION_PRINT): Remove. All callers changed to use location_print.

13313 (location_print): New decl.
13314 * src/parse-gram.y (lloc_default): New function, which handles
13315 empty locations more accurately.
13316 (YYLLOC_DEFAULT): Use it.
13317 (%token COLON): Remove.
13318 (%token ID_COLON): New token.
13319 (rules): Use it.
13320 (declarations, rules): Remove trailing semicolon.
13321 (declaration, rules_or_grammar_declaration):
13322 Allow empty (";") declaration.
13323 (symbol_def): Remove empty actions; no longer needed.
13324 (rules_or_grammar_declaration): Remove trailing semicolon.
13325 (semi_colon.opt): Remove.
13326 * src/reader.h: Include location.h.
13327 (scanner_cursor): New decl.
13328 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
13329 rolling our own.
13330 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
13331 of *loc.
13332 (STEP): Remove. No longer needed, now that adjust_location does
13333 the work. All uses removed.
13334 (scanner_cursor): New var.
13335 (adjust_location): Renamed from extend_location. It now sets
13336 *loc and adjusts the scanner cursor. All uses changed.
13337 Don't bother testing for CR.
13338 (handle_syncline): Remove location arg; now updates scanner cursor.
13339 All callers changed.
13340 (unexpected_end_of_file): Now accepts start boundary of token or
13341 comment, not location. All callers changed. Update scanner cursor,
13342 not the location.
13343 (SC_AFTER_IDENTIFIER): New state.
13344 (context_state): Renamed from c_context. All uses changed.
13345 (id_loc, code_start, token_start): New local vars.
13346 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
13347 processing of Yacc white space and equivalents here.
13348 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
13349 instead of returning ID immediately, since we need to search for
13350 a subsequent colon.
13351 (<INITIAL>"'", "\""): Save token_start.
13352 (<INITIAL>"%{", "{", "%%"): Save code_start.
13353 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
13354 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
13355 BEGIN context_state at end, not INITIAL.
13356 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
13357 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
13358 Return correct token start.
13359 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
13360 the start of a character, string or multiline comment is found.
13361 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
13362 Reduction): Adjust reported locations to match the more-precise
13363 results now expected.
13364 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
13365 * tests/reduce.at (Useless Rules, Reduced Automaton,
13366 Underivable Rules): Likewise.
13367 * tests/regression.at (Invalid inputs): No longer `expecting ";"
13368 or "|"' now that so many other tokens are allowed by the new grammar.
13369
13370 * src/complain.h (current_file): Remove duplicate decl;
13371 current_file is now owned by files.h.
13372 * src/complain.c, src/scan-gram.l: Include files.h.
13373
133742002-12-06 Paul Eggert <eggert@twinsun.com>
13375
13376 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
13377 promotes to int; it might be unsigned int.
13378 * data/yacc.c (yy_reduce_print): Likewise.
13379
13380 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
13381 be #defined in the prologue, not in the Bison declarations.
13382 This fixes Debian Bug 102878, reported by Shaul Karl.
13383
133842002-12-02 Paul Eggert <eggert@twinsun.com>
13385
13386 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
13387 * lib/strtoul.c: New file, from gnulib.
13388 This fixes a porting bug reported by Peter Klein in
13389 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13390
133912002-11-30 Paul Eggert <eggert@twinsun.com>
13392
13393 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13394 and put only a forward declaration in the prologue. This is for
13395 consistency with the other scanner helper functions.
13396
13397 Type clashes now generate warnings, not errors, since it
13398 appears that POSIX may allow some grammars with type clashes.
13399 * src/reader.c (grammar_current_rule_check): Warn about
13400 type clashes instead of complaining.
13401 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13402
13403 Add Yacc library, since POSIX requires it.
13404 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13405 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13406 * lib/main.c, lib/yyerror.c: New files.
13407
13408 gram_error can be static; it need not be extern.
13409 * src/reader.h (gram_error): Remove decl.
13410 * src/parse-gram.y (gram_error): Now static. Add static decl.
13411 (print_token_value): Omit parameter names from forward decl,
13412 for consistency.
13413
134142002-11-29 Paul Eggert <eggert@twinsun.com>
13415
13416 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13417 be declared before being used. E.g., one should typically
13418 declare them in the prologue. Use GNU coding style in examples.
13419 Put "const" consistently after the type it modifies. Mention
13420 that C99 supports "inline". Mention that yyerror traditionally
13421 returns "int".
13422
13423 %parse-param and %lex-param now take just one argument, the
13424 declaration; the argument name is deduced from the declaration.
13425
13426 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13427 Reporting, Table of Symbols): Document this.
13428 * src/parse-gram.y (add_param): New function.
13429 (COMMA): Remove.
13430 (declaration): Implement new rule for %parse-param and %lex-param.
13431 * src/scan-gram.l: "," now elicits a warning, rather than being
13432 a token; this is more compatible with byacc.
13433 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13434
134352002-11-27 Paul Eggert <eggert@twinsun.com>
13436
13437 Rename identifiers to avoid real and potential collisions.
13438
13439 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13440 to avoid collision with lex macro described by Bruce Lilly in
13441 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13442 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13443 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13444 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13445 All uses changed.
13446 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13447 The name "yycontrol" violates the name space rules, and this stuff
13448 wasn't being used anyway.
13449 (input): Remove action; this stuff wasn't being used.
13450 (gram_error): Rename local variable yylloc -> loc.
13451 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13452 (YY_DECL): Don't use "yy" at start of local variables.
13453 All uses changed, e.g., yylloc -> loc.
13454 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
13455 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
13456 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
13457 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
13458
13459 * src/parse-gram.y (gram_error): loc is now const *.
13460 * src/reader.h (gram_error): Likewise.
13461
134622002-11-24 Paul Eggert <eggert@twinsun.com>
13463
13464 Version 1.75c.
13465
13466 * tests/actions.at (Actions after errors): Use an output format
13467 more similar to that of the Printers and Destructors test.
13468 Test the position of the ';' token too.
13469 (Printers and Destructors): Likewise.
13470 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13471 unnecessarily alarming people when the test fails.
13472
13473 * data/yacc.c (yyerrlab1): Move this label down, so that the
13474 parser does not discard the lookahead token if the user code
13475 invokes YYERROR. This change is required for POSIX conformance.
13476
13477 * lib/error.c: Sync with gnulib.
13478
134792002-11-22 Paul Eggert <eggert@twinsun.com>
13480
13481 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
13482 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
13483 * lib/xmalloc.c: Likewise.
13484
134852002-11-20 Paul Eggert <eggert@twinsun.com>
13486
13487 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13488
134892002-11-20 Paul Eggert <eggert@twinsun.com>
13490
13491 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13492 should use `if (! x) abort ();' rather than `assert (x);', and
13493 anyway it's one less thing to worry about configuring.
13494
13495 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13496 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13497 and replace all instances of assert with abort.
13498 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
13499 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
13500

13503 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
13504 hash_find_entry, hash_rehash, hash_insert): Likewise.
13505 * src/conflicts.c (resolve_sr_conflict): Likewise.
13506 * src/lalr.c (set_goto_map, map_goto): Likewise.
13507 * src/nullable.c (nullable_compute): Likewise.
13508 * src/output.c (prepare_rules, token_definitions_output): Likewise.
13509 * src/reader.c (packgram, reader): Likewise.
13510 * src/state.c (state_new, state_free, state_transitions_set,
13511 state_reduction_find): Likewise.
13512 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
13513 symbol_pack): Likewise.
13514 * src/tables.c (conflict_row, pack_vector): Likewise.
13515 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13516 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13517 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
13518 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
13519
13520 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
13521 (ARGMATCH_CONSTRAINT): New macro.
13522 (ARGMATCH_ASSERT): Use it.
13523
13524 * src/system.h (verify): New macro.
13525 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
13526 rather than assert.
13527 * src/tables.c (tables_generate): Likewise.
13528
13529 * src/struniq.c (struniq_assert): Now returns void, and aborts
13530 if the assertion is false.
13531 (struniq_assert_p): Remove.
13532 * src/struniq.h: Likewise.
13533
135342002-11-18 Paul Eggert <eggert@twinsun.com>
13535
13536 * data/glr.c (yygetLRActions): Replace `yyindex' with
13537 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
13538 This fixes the regression with Sun ONE Studio 7 cc that I reported in
13539 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
13540
135412002-11-18 Akim Demaille <akim@epita.fr>
13542
13543 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
13544 space.
13545 From Tim Van Holder.
13546
135472002-11-17 Paul Eggert <eggert@twinsun.com>
13548
13549 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
13550 to "SyntaxError" for consistency with my 2002-11-15 change.
13551
13552 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
13553 not define to {}, since this breaks the common use of `YYDPRINTF
13554 ((...));' if a single statement is desired (e.g. before `else').
13555 Work around GCC warnings by surrounding corresponding calls with
13556 {} if needed.
13557 (yyhasResolvedValue): Remove unused function.
13558 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
13559 loop body.
13560 (yyreportSyntaxError): Renamed from yyreportParseError.
13561 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
13562 All uses changed.
13563 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
13564 extern when possible. Remove unused initializations.
13565
135662002-11-16 Akim Demaille <akim@epita.fr>
13567
13568 Augment the similarity between GLR and LALR traces.
13569
13570 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
13571 (YY_REDUCE_PRINT): New.
13572 (yyparse): Use them.
13573 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
13574 YYDPRINT here.
13575 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
13576 state reached after the reduction/recovery, since...
13577 (yyparse, yyprocessOneStack): Report the state we are entering in.
13578
135792002-11-16 Akim Demaille <akim@epita.fr>
13580
13581 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
13582 Add support for --trace=skeleton.
13583 * src/scan-skel.l: %option debug.
13584 Scan strings of non-@ or \n instead of character by character.
13585 (scan_skel): Handle trace_skeleton.
13586 (QPUTS): New.
13587 (@output_parser_name@, @output_header_name@): ``Restore'' their
13588 support (used to be M4 macros).
13589 * data/yacc.c: Quote larger chunks, a la glr.c.
13590 * data/lalr1.cc: Likewise.
13591 The header guards are no longer available, so use some other
13592 string than `YYLSP_NEEDED'.
13593
135942002-11-16 Akim Demaille <akim@epita.fr>
13595
13596 Make the ``Printers and Destructors'' test more verbose, taking
13597 `yacc.c''s behavior as (possibly wrong) reference.
13598
13599 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
13600 instead of fprint on stdout.
13601 Set and report the last_line of the symbols.
13602 Consistently display values and locations.
13603
136042002-11-16 Paul Eggert <eggert@twinsun.com>
13605
13606 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
13607
136082002-11-15 Paul Eggert <eggert@twinsun.com>
13609
13610 * tests/actions.at (Actions after errors): New test case.
13611
13612 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
13613 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
13614 tests/action.at, tests/calc.at, tests/conflicts.at,
13615 tests/cxx-type.at, tests/regression.at:
13616 "parse error" -> "syntax error" for POSIX compatibility.
13617 "parsing stack overflow..." -> "parser stack overflow" so
13618 that code matches Bison documentation.
13619
136202002-11-15 Akim Demaille <akim@epita.fr>
13621
13622 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
13623 take two BRACED_CODE, not two string_content.
13624 Free the scanner's obstack when we are done.
13625 (code_content): New.
13626 * tests/calc.at: Adjust.
13627 * doc/bison.texinfo: Adjust.
13628 Also, make sure to include the `,' for these declarations.
13629
136302002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
13631
13632 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
13633 definition; avoids potential autoreconf problems.
13634
136352002-11-15 Akim Demaille <akim@epita.fr>
13636
13637 Always check the value returned by yyparse.
13638
13639 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
13640 returned by yyparse.
13641 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
13642 Adjust calls.
13643 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
13644 returned by yyparse.
13645
136462002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13647
13648 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
13649 on input.at test.
13650
136512002-11-14 Paul Eggert <eggert@twinsun.com>
13652
13653 * src/output.c (output_skeleton): Call xfopen instead of
13654 duplicating xfopen's body.
13655
13656 Fix bugs reported by Nelson H. F. Beebe in
13657 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
13658
13659 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
13660 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
13661 Group compiler. Instead, use "$CC -E bar.c". Include the .h
13662 file twice in the grammar, as an extra check.
13663
13664 * tests/input.at (Torturing the Scanner): Surround the
13665 backslash-newline tests with "#if 0", to make it less likely that
13666 we'll run into compiler bugs. Bring back solitary \ inside
13667 comment, but add a closing comment to work around HP C bug. Don't
13668 test backslash-newline in C character constant.
13669
136702002-11-14 Akim Demaille <akim@epita.fr>
13671
13672 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
13673 status of the compiler.
13674 Calling `exit 1' is no longer needed.
13675 Reported by Nelson H. F. Beebe.
13676
136772002-11-14 Akim Demaille <akim@epita.fr>
13678
13679 * tests/atlocal.in (CPPFLAGS): We have config.h.
13680 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
13681 New.
13682 * tests/actions.at, tests/calc.at, tests/conflicts.at,
13683 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
13684 * tests/regression.at, tests/torture.at: Use them for all the
13685 grammars that are to be compiled.
13686 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
13687 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
13688 * doc/bison.texinfo (GLR Parsers): Document `inline'.
13689
136902002-11-14 Akim Demaille <akim@epita.fr>
13691
13692 * doc/bison.texinfo: Various formatting changes (alignments in
13693 samples, additional @group/@end group, GCS in samples.
13694 Use @deffn instead of simple @table to define the directives,
13695 macros, variables etc.
13696
136972002-11-13 Paul Eggert <eggert@twinsun.com>
13698
13699 Fix some bugs reported by Albert Chin-A-Young in
13700 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
13701
13702 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
13703 -o c"; the HP C compiler chatters during compilation.
13704 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
13705 * tests/headers.at (export YYLTYPE): Likewise.
13706
13707 * tests/input.at (Torturing the Scanner): Remove lines containing
13708 solitary backslashes, as they tickle a bug in the HP C compiler.
13709
13710 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //

137132002-11-13 Akim Demaille <akim@epita.fr>
13714
13715 * data/yacc.c: Leave bigger chunks of quoted text.
13716 (YYDSYMPRINTF): New.
13717 Use it to report symbol activities.
13718 * data/glr.c (YYDSYMPRINTF): New.
13719 Use it.

137212002-11-12 Paul Eggert <eggert@twinsun.com>
13722
13723 Version 1.75b.
13724
13725 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
13726 (yyglrReduce): Return yyok, not 0.
13727 This should avoid the enumerated-type warnings reported
13728 by Nelson H. F. Beebe in
13729 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
13730
13731 * lib/bbitset.h (BITSET_INLINE): Remove.
13732 * lib/bitset.h [! BITSET_INLINE]: Remove.
13733 (bitset_set, bitset_reset, bitset_test): Rename local vars
13734 to avoid shadowing warnings by GCC.
13735
13736 * data/glr.c (inline): Remove #define. It's the user's
13737 responsibility to #define it away, just like 'const'.
13738 This fixes one of the bugs reported by Nelson H. F. Beebe in
13739 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
13740
13741 * Makefile.maint (po-check): Scan .l and .y files instead of the
13742 .c and the .h files that they generate. This fixes the bug
13743 reported by Tim Van Holder in:
13744 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
13745 Look for N_ as well as for _. Try to avoid matching #define for
13746 N_ and _.
13747 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
13748 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
13749 * src/scan-gram.l: Revamp regular expressions so that " and '
13750 do not confuse xgettext.
13751
13752 * src/struniq.h (struniq_new): Do not declare the return type
13753 to be 'const'; this violates the C standard.
13754 * src/struniq.c (struniq_new): Likewise.
13755
137562002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
13757
13758 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
13759 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
13760 linker.
13761
137622002-11-12 Akim Demaille <akim@epita.fr>
13763

13768
13769 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
13770
137712002-11-12 Akim Demaille <akim@epita.fr>
13772
13773 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
13774 locations.
13775
137762002-11-12 Akim Demaille <akim@epita.fr>
13777
13778 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
13779 not yyvalue.
13780
137812002-11-12 Akim Demaille <akim@epita.fr>
13782
13783 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
13784 Use it to test the GLR parser.

137862002-11-12 Akim Demaille <akim@epita.fr>
13787
13788 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
13789 defines it.
13790 * data/glr.c (yystos): New.
13791 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
13792 (YYDSYMPRINT): New.
13793 (yyval): Don't define it, it is handled via M4.
13794 (yyrecoverParseError): Free verbosely the discarded symbols.
13795 * data/yacc.c (yysymprint): Remove, rather...
13796 (b4_yysymprint_generate): invoke.
13797 * data/c.m4 (b4_yysymprint_generate): New.
13798 Accept pointers as arguments, as opposed to the version from
13799 yacc.c.
13800 (b4_yydestruct_generate): Likewise.
13801 * tests/cations.at (Printers and Destructors): Use Bison directives
13802 instead of CPP macros.
13803 Don't rely on internal details.
13804
138052002-11-12 Akim Demaille <akim@epita.fr>
13806
13807 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
13808 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
13809 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
13810 it against YYEMPTY and so forth), work on yytoken (i.e., set
13811 it to YYEMPTY etc.).
13812 (yydestruct): Replace with a b4_yydestruct_generate invocation.
13813 (b4_symbol_actions): Remove.
13814 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
13815 for 0, end-of-input.
13816
138172002-11-12 Akim Demaille <akim@epita.fr>
13818
13819 * doc/bison.texinfo (Destructor Decl): New.
13820
138212002-11-12 Akim Demaille <akim@epita.fr>
13822
13823 * src/tables.c (tables_generate): Use free for pointers that
13824 cannot be NULL, not XFREE.
13825 (pack_vector): Use assert, not fatal, for bound violations.
13826 * src/state.c (state_new): Likewise.
13827 * src/reader.c (reader): Likewise.
13828 * src/lalr.c (set_goto_map): Likewise.
13829 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
13830 the file name.
13831
138322002-11-12 Akim Demaille <akim@epita.fr>
13833
13834 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
13835 Restore.
13836 * src/scan-gram.l (last_string): Is global to the file, not to
13837 yylex.
13838 * src/parse-gram.y (input): Don't append the epilogue here,
13839 (epilogue.opt): do it here, and free the scanner's obstack.
13840 * src/reader.c (epilogue_set): Rename as...
13841 (epilogue_augment): this.
13842 * data/c.m4 (b4_epilogue): Defaults to empty.
13843
138442002-11-12 Akim Demaille <akim@epita.fr>
13845
13846 * src/getargs.c (long_options): Remove duplicates.
13847 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
13848 Remove.

13850 * doc/bison.texinfo (VMS Invocation): Remove.
13851
138522002-11-12 Akim Demaille <akim@epita.fr>
13853
13854 * src/struniq.h, src/struniq.c (struniq_t): Is const.
13855 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
13856
13857 Use struniq for symbols.
13858
13859 * src/symtab.h (symbol_t): The tag member is a struniq.
13860 (symbol_type_set): Adjust.
13861 * src/symtab.c (symbol_new): Takes a struniq.
13862 (symbol_free): Don't free the tag member.
13863 (hash_compare_symbol_t, hash_symbol_t): Rename as...
13864 (hash_compare_symbol, hash_symbol): these.
13865 Use the fact that tags as struniqs.
13866 (symbol_get): Use struniq_new.
13867 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
13868 Returns a strniq.
13869 * src/reader.h (merger_list, grammar_currentmerge_set): The name
13870 and type members are struniqs.
13871 * src/reader.c (get_merge_function)
13872 (grammar_current_rule_merge_set): Adjust.
13873 (TYPE, current_type): Are struniq.
13874
13875 Use struniq for file names.
13876
13877 * src/files.h, src/files.c (infile): Split into...
13878 (grammar_file, current_file): these.
13879 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.
13880 * src/reduce.c (reduce_print): Likewise.
13881 * src/getargs.c (getargs): Likewise.
13882 * src/complain.h, src/complain.c: Likewise.
13883 * src/main.c (main): Call struniqs_new early enough to use it for
13884 file names.
13885 Don't free the input file name.
13886
138872002-11-12 Akim Demaille <akim@epita.fr>
13888
13889 * src/symtab.c (symbol_free): Remove dead deactivated code:
13890 type_name are properly removed.
13891 Don't use XFREE to free items that cannot be NULL.
13892 * src/struniq.h, src/struniq.c: New.

13899
139002002-11-11 Paul Eggert <eggert@twinsun.com>
13901
13902 Revamp to fix many (but not all) of the C- and M4-related quoting
13903 problems. Among other things, this fixes the Bison bug reported
13904 by Jan Hubicka when processing the Bash grammar; see:
13905 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
13906
13907 Use new @ escapes consistently. Represent brackets with @{ and @}
13908 rather than @<:@ and @:>@, since this works a bit better with dumb
13909 editors like vi. Represent @ with @@, since @ is now consistently
13910 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13911 __ofile__, to avoid unexpected expansions. Similarly, use @output
13912 rather than #output.
13913
13914 * data/c.m4 (b4_copyright): Omit file name from comment, since
13915 the file name could contain "*/".
13916 (b4_synclines_flag): Don't quote the 2nd argument; it should already
13917 be quoted. All uses changed.
13918
13919 * data/glr.c: Use new @ escapes consistently.
13920 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
13921 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
13922 Remove, since they couldn't handle arbitrary characters in file
13923 names.
13924 * data/lalr1.cc: Likewise.
13925 * data/yacc.c: Likewise.
13926
13927 * src/files.c (output_infix): Remove; all uses removed.
13928 * src/files.h: Likewise.
13929
13930 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
13931 mishandled funny characters in file names, and anyway it isn't
13932 needed any more.
13933 * data/yacc.c: Likewise.
13934 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
13935
13936 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
13937 * data/yacc.c: Likewise.
13938
13939 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
13940 strings now.
13941 (muscle_init): Quote filename as a C string.
13942 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
13943 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
13944 * src/output.c (escaped_file_name_output): New function.
13945 (prepare_symbols): Quote tokens for M4.
13946 (prepare): Don't insert output_infix, output_prefix,
13947 output_parser_name, output_header_name; this is now down by scan-skel.
13948 Insert skeleton as a C string.
13949
13950 * src/output.c (user_actions_output, symbol_destructors_output,
13951 symbol_printers_output): Quote filenames for C and M4.
13952 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13953
13954 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
13955 escapes other than \\ and \'; this simplifies the code.
13956 (<SC_STRING>): Likewise, for \\ and \".
13957 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13958 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13959 Use new escapes @{ and @} for [ and ].
13960
13961 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13962 them with auto vars.
13963 Switch to new escape scheme, where @ is the escape character uniformly.
13964 Abort if a stray escape character is found. Avoid unbounded input
13965 buffer when parsing non-escaped text.
13966
13967 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
13968 __oline__, #output, $@, and @{ do not have unintended meanings.
13969
139702002-11-09 Paul Eggert <eggert@twinsun.com>
13971
13972 Fix the test failure due to GCC warnings described in
13973 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
13974 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
13975 evaluate to 0 if it's impossible for NINF to be in the respective
13976 table.
13977 (yygetLRActions, yyrecoverParseError): Use them.
13978
13979 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13980 counted in the token inserted at end of file. Now takes
13981 location_t *, not location_t, so that the location can be
13982 adjusted. All uses changed.
13983
13984 * tests/regression.at (Invalid inputs): Adjust wording in
13985 diagnostic to match the new behavior.
13986
13987 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13988 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13989 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13990 abort ();'. This reduces the runtime of the "Many lookaheads"
13991 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13992 GCC 3.2.
13993
139942002-11-07 Paul Eggert <eggert@twinsun.com>
13995
13996 * src/parse-gram.y (CHARACTER): Remove unused token.
13997 All uses removed.
13998
13999 * src/scan-gram.l: Remove stack option. We no longer use the
14000 stack, since the stack was never deeper than 1; instead, use the
14001 new auto var c_context to record the stacked value.
14002
14003 Remove nounput option. At an unexpected end of file, we now unput
14004 the minimal input necessary to end cleanly; this simplifies the
14005 code.
14006
14007 Avoid unbounded token sizes where this is easy.
14008
14009 (unexpected_end_of_file): New function.
14010 Use it to systematize the error message on unexpected EOF.
14011 (last-string): Now auto, not static.
14012 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
14013 (scanner_last_string_free): Remove; not used.
14014 (percent_percent_count): Move decl to just before use.
14015 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
14016 not the (never otherwised-used) CHARACTER.
14017
140182002-11-07 Akim Demaille <akim@epita.fr>
14019
14020 Let yyerror always receive the msg as last argument, so that
14021 yyerror can be variadic.
14022
14023 * data/yacc.c (b4_yyerror_args): New.
14024 Use it when calling yyerror.
14025 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
14026 Use it when calling yyerror.
14027 * doc/bison.texinfo (Error Reporting): Adjust.
14028 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
14029 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
14030
140312002-11-06 Akim Demaille <akim@epita.fr>
14032
14033 #line should have quoted strings.
14034 Ideally, this should be done by m4_quotearg.
14035
14036 * src/scan-skel.l: Include quotearg.h.
14037 Quote __ofile__.
14038 * src/output.c (symbol_printers_output)
14039 (symbol_destructors_output): Quote the file name.
14040
140412002-11-06 Akim Demaille <akim@epita.fr>
14042
14043 * tests/regression.at (Invalid inputs): Adjust to the recent
14044 messages.
14045
140462002-11-06 Akim Demaille <akim@epita.fr>
14047
14048 Restore --no-lines.
14049 Reported by Jim Kent.
14050
14051 * data/c.m4 (b4_syncline): New.
14052 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
14053 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
14054 * src/output.c (user_actions_output): Likewise.
14055 (prepare): Define 'b4_synclines_flag'.
14056 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
14057
140582002-11-06 Akim Demaille <akim@epita.fr>
14059
14060 * src/main.c (main): Free `infile'.
14061 * src/scan-gram.l (handle_syncline): New.
14062 Recognize `#line'.
14063 * src/output.c (user_actions_output, symbol_destructors_output)
14064 (symbol_printers_output): Use the location's file name, not
14065 infile.
14066 * src/reader.c (prologue_augment, epilogue_set): Likewise.
14067
140682002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14069
14070 * src/tables.c (matching_state): Don't allow states to match if
14071 either has GLR conflict entries.
14072
140732002-11-05 Paul Eggert <eggert@twinsun.com>
14074
14075 * src/scan-gram.l: Use more accurate diagnostics, e.g.
14076 "integer out of range" rather than "invalid value".
14077 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
14078 accordingly.
14079
14080 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
14081 Also, remove one static variable in the scanner.
14082
14083 * src/scan-gram.l (braces_level): Now auto, not static.
14084 Initialize to zero if the compiler is being picky.
14085 (INITIAL): Clear braces_level instead of incrementing it.
14086 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
14087 as POSIX 1003.1-2001 requires.
14088 * src/system.h (IF_LINT): New macro, taken from coreutils.
14089 * configure.ac: Define "lint" if --enable-gcc-warnings.
14090
140912002-11-05 Akim Demaille <akim@epita.fr>
14092
14093 * src/scan-gram.l: When it starts with `%', complain about the
14094 whole directive, not just that `invalid character: %'.
14095
140962002-11-04 Akim Demaille <akim@epita.fr>
14097
14098 * Makefile.maint: Update from Autoconf.

14100
141012002-11-04 Akim Demaille <akim@epita.fr>
14102
14103 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
14104 and yyerror.
14105 Have yyerror `use' its arguments.
14106 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
14107 returns true when location & yacc & pure & parse-param.
14108 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
14109
141102002-11-04 Akim Demaille <akim@epita.fr>
14111
14112 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
14113 clashes.
14114 * src/scan-gram.l: Use [\'] instead of ['] to pacify
14115 font-lock-mode.
14116 Use complain_at.
14117 Use quote, not quote_n since LOCATION_PRINT no longer uses the
14118 slot 0.
14119
141202002-11-03 Paul Eggert <eggert@twinsun.com>
14121
14122 * src/reader.c (get_merge_function, grammar_current_rule_check):

14140 b4_user_formals and b4_user_args.
14141 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
14142 (yyreportAmbiguity): When using a pure parser, also need
14143 the location, and the parse-params.
14144 Adjust callers.
14145 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
14146 When using a pure parser, also need the parse-params.
14147 Adjust callers.
14148 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
14149 (%pure-parser + %parse-param) LALR and GLR parsers.
14150 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
14151 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

14160 Document %error-verbose, deprecate YYERROR_VERBOSE.
14161
141622002-11-03 Akim Demaille <akim@epita.fr>
14163
14164 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
14165 AT_CHECK_CALC_GLR invocations to use % directives, instead of
14166 command line options.
14167 * tests/cxx-type.at: Formatting changes.
14168
141692002-11-03 Paul Eggert <eggert@twinsun.com>
14170
14171 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
14172 to count columns correctly, and to check for invalid inputs.
14173
14174 Use mbsnwidth to count columns correctly. Account for tabs, too.
14175 Include mbswidth.h.
14176 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
14177 (extend_location): New function.
14178 (YY_LINES): Remove.
14179
14180 Handle CRLF in C code rather than in Lex code.
14181 (YY_INPUT): New macro.
14182 (no_cr_read): New function.
14183
14184 Scan UCNs, even though we don't fully handle them yet.
14185 (convert_ucn_to_byte): New function.
14186
14187 Handle backslash-newline correctly in C code.
14188 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
14189 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
14190 all uses changed.
14191 (tag, splice): New EREs. Do not allow NUL or newline in tags.
14192 Use {splice} wherever C allows backslash-newline.
14193 YY_STEP after space, newline, vertical-tab.
14194 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
14195
14196 (letter, id): Don't assume ASCII; e.g., spell out a-z.
14197
14198 ({int}, handle_action_dollar, handle_action_at): Check for integer
14199 overflow.
14200
14201 (YY_STEP): Omit trailing semicolon, so that it's more like C.
14202
14203 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
14204 as well as \000. Check for UCHAR_MAX, not 255.
14205 Allow \x with an arbitrary positive number of digits, as in C.
14206 Check for overflow here.
14207 Allow \? and UCNs, for compatibility with C.
14208
14209 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
14210 with quote slot used by complain_at.
14211
14212 * tests/input.at: Add tests for backslash-newline, m4 quotes
14213 in symbols, long literals, and funny escapes in strings.
14214
14215 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
14216 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
14217 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
14218 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
14219 * m4/mbswidth.m4: New file, from GNU coreutils.
14220
14221 * doc/bison.texinfo (Grammar Outline): Document // comments.
14222 (Symbols): Document that trigraphs have no special meaning in Bison,
14223 nor is backslash-newline allowed.
14224 (Actions): Document that trigraphs have no special meaning.
14225
14226 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
14227 no longer used.
14228
142292002-11-02 Paul Eggert <eggert@twinsun.com>
14230
14231 * src/reader.c: Don't include quote.h; not needed.
14232 (get_merge_function): Reword warning to be consistent with
14233 type clash diagnostic in grammar_current_rule_check.
14234
14235 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
14236 bug in trigraph handling.
14237
14238 * src/output.c (prepare_symbols): When printing token names,
14239 escape "[" as "@<:@" and likewise for "]".
14240
14241 * src/system.h (errno): Remove declaration, as we are now
14242 assuming C89 or better, and C89 guarantees errno.
14243
142442002-10-30 Paul Eggert <eggert@twinsun.com>
14245
14246 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
14247 Check for close failures.
14248 * src/files.h (xfclose): Return void, not int, since it always
14249 returned zero.
14250 * src/files.c (xfclose): Likewise. Report I/O error if ferror
14251 indicates one.
14252 * src/output.c (output_skeleton): Use xfclose rather than fclose
14253 and ferror. xfclose now checks ferror.
14254
14255 * data/glr.c (YYLEFTMOST_STATE): Remove.
14256 (yyreportTree): Use a stack-based leftmost state. This avoids
14257 our continuing battles with bogus warnings about initializers.
14258
142592002-10-30 Akim Demaille <akim@epita.fr>
14260
14261 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
14262 #if.
14263
142642002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14265
14266 * tests/glr-regr1.at: New test for reported regressions.
14267 * tests/testsuite.at: Add glr-regr1.at test.
14268 * tests/Makefile.am: Add glr-regr1.at test.
14269
142702002-10-24 Paul Eggert <eggert@twinsun.com>
14271
14272 Version 1.75a.
14273
14274 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
14275 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
14276 we use malloc. Don't assume 'A' through 'Z' are contiguous.
14277 Don't assume strdup exists; POSIX says its an XSI extension.
14278 Check for buffer overflow on input.
14279
142802002-10-24 Akim Demaille <akim@epita.fr>
14281
14282 * src/output.c (output_skeleton): Don't disable M4sugar comments
14283 too soon: it results in comments being expanded.
14284 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
14285 first output.
14286
142872002-10-24 Akim Demaille <akim@epita.fr>
14288
14289 * data/yacc.c (m4_int_type): New.
14290 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
14291 char' as only yacc.c wants K&R portability.
14292 * data/glr.c (yysigned_char): Remove.
14293 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
14294 Reported by Quoc Peyrot.
14295
142962002-10-23 Paul Eggert <eggert@twinsun.com>
14297
14298 * src/main.c (main): With --trace=time, report times even if a
14299 non-fatal error occurs. Formerly, the times were reported in some
14300 such cases but not in others.
14301 * src/reader.c (reader): Just return if a complaint has been issued,
14302 instead of exiting, so that 'main' can report times.
14303
143042002-10-22 Akim Demaille <akim@epita.fr>
14305
14306 * src/system.h: Include sys/types.
14307 Reported by Bert Deknuydt.
14308
143092002-10-23 Paul Eggert <eggert@twinsun.com>
14310
14311 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
14312 Suggested by Art Haas.
14313
143142002-10-22 Paul Eggert <eggert@twinsun.com>
14315
14316 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14317 decl; not needed any more.
14318 * src/main.c (main): Use return to exit, undoing yesterday's change.
14319 The last OS that we could find where this wouldn't work is
14320 SunOS 3.5, and that's too old to worry about now.
14321
14322 * data/glr.c (struct yyltype): Define members even when not
14323 doing locations. This is more consistent with yacc.c, and it
14324 works around the following bug reports:
14325 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
14326 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
14327
14328 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
14329 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14330 "Algol" instead of "ALGOL". Give a bit more history about BNF.
14331
143322002-10-22 Akim Demaille <akim@epita.fr>
14333
14334 * data/README: New.
14335
143362002-10-21 Paul Eggert <eggert@twinsun.com>
14337
14338 Be consistent about 'bool'; the old code used an enum in one
14339 module and an int in another, and this violates the C standard.
14340 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14341 * configure.ac (AC_HEADER_STDBOOL): Add.
14342 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14343 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14344 * src/symtab.c (hash_compare_symbol_t): Likewise.
14345 * src/system.h (bool, false, true): Use a definition consistent
14346 with ../lib/hash.c. All uses changed.
14347
14348 * src/complain.c (warning_issued): Renamed from warn_message_count,
14349 so that we needn't worry about integer overflow (!).
14350 Now of type bool. All uses changed.
14351 (complaint_issued): Renamed from complain_message_count; likewise.
14352
14353 * src/main.c (main): Use exit to exit with failure.
14354
14355 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
14356 rather than 1 and 0.
14357 * src/main.c (main): Likewise.
14358 * src/getargs.c (getargs): Likewise.
14359 * src/reader.c (reader): Likewise.
14360
14361 * src/getarg.c (getargs): Remove duplicate code for
14362 "Try `bison --help'".
14363
14364 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
14365 What was that "2" for?
14366
14367 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14368 * src/getargs.c (usage): Likewise.
14369
14370 * src/getargs.c (getargs): When there are too few operands, report
14371 the last one. When there are too many, report the first extra
14372 one. This is how diffutils does it.
14373
143742002-10-20 Paul Eggert <eggert@twinsun.com>
14375
14376 Remove K&R vestiges.
14377 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
14378 * src/complain.c (VA_START): Remove. Assume prototypes.
14379 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
14380 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
14381 fatal): Assume prototypes.
14382 * src/complain.h: Assume prototypes.
14383 * src/system.h (PARAMS): Remove.
14384 Include <limits.h> unconditionally, since it's guaranteeed even
14385 for a freestanding C89 compiler.
14386 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
14387 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
14388
143892002-10-20 Akim Demaille <akim@epita.fr>
14390
14391 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
14392 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
14393 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
14394 (yyresolveStates, yyresolveAction, yyresolveStack)
14395 (yyprocessOneStack): Use them.
14396 (yy_reduce_print): New.
14397 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
14398
143992002-10-20 Akim Demaille <akim@epita.fr>
14400
14401 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14402 arguments and output `void'.
14403 (b4_c_function): Rename as...
14404 (b4_c_function_def): this.
14405 (b4_c_function_decl, b4_c_ansi_function_def)
14406 (b4_c_ansi_function_decl): New.
14407 Change the interpretation of the arguments: before `int, foo', now
14408 `int foo, foo'.
14409 * data/yacc.c (yyparse): Prototype and define thanks to these.
14410 Adjust b4_c_function_def uses.
14411 * data/glr.c (yyparse): Likewise, but ANSI only.
14412
144132002-10-20 Akim Demaille <akim@epita.fr>
14414
14415 * src/output.c (prepare): Move the definition of `tokens_number',
14416 `nterms_number', `undef_token_number', `user_token_number_max'
14417 to...
14418 (prepare_tokens): Here.
14419 (prepare_tokens): Rename as...
14420 (prepare_symbols): this.
14421 (prepare): Move the definition of `rules_number' to...
14422 (prepare_rules): here.
14423 (prepare): Move the definition of `last', `final_state_number',
14424 `states_number' to...
14425 (prepare_states): here.
14426 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
14427
144282002-10-20 Akim Demaille <akim@epita.fr>
14429
14430 * src/tables.h, src/tables.c, src/output.c: Comment changes.
14431
144322002-10-20 Akim Demaille <akim@epita.fr>
14433
14434 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
14435 * data/c.m4: here.
14436
144372002-10-20 Akim Demaille <akim@epita.fr>
14438
14439 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
14440 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
14441 `pair'.
14442 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
14443 `name' to...
14444 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
14445 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
14446 These.
14447
144482002-10-19 Paul Eggert <eggert@twinsun.com>
14449
14450 Do not create a temporary file, as that involves security and
14451 cleanup headaches. Instead, use a pair of pipes.
14452 Derived from a suggestion by Florian Krohm.
14453 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14454 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
14455 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
14456 (BISON_PREREQ_SUBPIPE): Add.
14457 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
14458 Add subpipe.h, subpipe.c.
14459 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
14460 * po/POTFILES.in: Add lib/subpipe.c.
14461 * src/output.c: Include "subpipe.h".
14462 (m4_invoke): Remove decl.
14463 (scan_skel): New decl.
14464 (output_skeleton): Use pipe rather than temporary file for m4 input.
14465 Check that m4sugar.m4 is readable, to avoid deadlock.
14466 Check for pipe I/O error.
14467 * src/scan-skel.l (readpipe): Remove decl.
14468 (scan_skel): New function, to be used in place of m4_invoke.
14469 Read from stream rather than file.
14470
14471 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14472 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14473 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14474 this generates a more-accurate value anyway.
14475
14476 * lib/timevar.c (timervar_accumulate): Rename locals to
14477 avoid confusion with similarly-named more-global.
14478 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14479
14480 * src/output.c (prepare): Use xstrdup to convert char const *
14481 to char *, to avoid GCC warning.
14482
144832002-10-19 Akim Demaille <akim@epita.fr>
14484
14485 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14486 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14487 Use them to have `calc.y' ready for %pure-parser.
14488 * data/yacc.c (YYLEX): Pass a yylex return type to
14489 b4_c_function_call.
14490
144912002-10-19 Akim Demaille <akim@epita.fr>
14492
14493 Prototype support of %lex-param and %parse-param.
14494
14495 * src/parse-gram.y: Add the definition of the %lex-param and
14496 %parse-param tokens, plus their rules.
14497 Drop the `_' version of %glr-parser.
14498 Add the "," token.
14499 * src/scan-gram.l (INITIAL): Scan them.
14500 * src/muscle_tab.c: Comment changes.
14501 (muscle_insert, muscle_find): Rename `pair' as `probe'.
14502 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
14503 (muscle_entry_s): The `value' member is no longer const.
14504 Adjust all dependencies.
14505 * src/muscle_tab.c (muscle_init): Adjust: use
14506 MUSCLE_INSERT_STRING.
14507 Initialize the obstack earlier.
14508 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14509 (muscle_pair_list_grow): New.
14510 * data/c.m4 (b4_c_function_call, b4_c_args): New.
14511 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
14512 * tests/calc.at: Use %locations, not --locations.
14513 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14514
145152002-10-19 Akim Demaille <akim@epita.fr>
14516
14517 * src/getargs.c (usage): Take status as argument and exit
14518 accordingly.
14519 Report the traditional `Try ... --help' message when status != 0.
14520 (usage, version): Don't take a FILE * as arg, it is pointless.
14521 (getargs): When there is an incorrect number of arguments, make it
14522 an error, and report it GNUlically thanks to `usage ()'.

14525
14526 * data/glr.c (yyreportParseError): Don't assume that sprintf
14527 yields the length of the printed string, as this is not true
14528 on SunOS 4.1.4. Reported by Peter Klein.
14529
14530 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14531 * tests/conflicts.at (%nonassoc and eof): Likewise.
14532 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14533
145342002-10-17 Akim Demaille <akim@epita.fr>
14535
14536 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14537 * src/getargs.c (trace_types, trace_args): Adjust.
14538 * src/reader.c (grammar_current_rule_prec_set)
14539 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
14540 Standardize error messages.
14541 And s/@prec/%prec/!
14542 (reader): Use trace_flag to enable scanner/parser debugging,
14543 instead of an adhoc scheme.
14544 * src/scan-gram.l: Remove trailing debugging code.

145462002-10-16 Paul Eggert <eggert@twinsun.com>

14549 MUSCLE_TAB_H.
14550
14551 * NEWS: Officially drop support for building Bison with K&R C,
14552 since it didn't work anyway and it's not worth worrying about.
14553 * Makefile.maint (wget_files): Remove ansi2knr.c.
14554 (ansi2knr.c-url_prefix): Remove.

14560
14561 Stop using the "enum_" trick for K&R-style function definitions;
14562 it confused me, and I was the author! Instead, assume that people
14563 who want to use K&R C compilers (when using these modules in GCC,
14564 perhaps?) will run ansi2knr.
14565
14566 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
14567 All uses of "enum_" changed to "enum ".

146432002-10-14 Akim Demaille <akim@epita.fr>
14644
14645 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
14646 member.

146482002-10-14 Akim Demaille <akim@epita.fr>

14654
14655 * tests/action.at, tests/calc.at, tests/conflicts.at,
14656 tests/cxx-type.at, tests/headers.at, tests/input.at,
14657 tests/regression.at, tests/synclines.at, tests/torture.at:
14658 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
14659 so that the tests still work even if POSIXLY_CORRECT is set.
14660 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
14661
14662 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
14663 for portability to K&R hosts. Fix typo: signed char is guaranteed
14664 only to 127, not to 128.
14665 * data/glr.c (yysigned_char): New type.
14666 * data/yacc.c (yysigned_char): Likewise.
14667 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
14668
146692002-10-13 Paul Eggert <eggert@twinsun.com>
14670
14671 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
14672 true due to limited range of data type" warning from GCC.
14673
14674 * data/c.m4 (b4_token_defines): Protect against double-inclusion
14675 by wrapping enum yytokentype's definition inside #ifndef
14676 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
14677
146782002-10-13 Akim Demaille <akim@epita.fr>
14679

14695
14696 Let nondeterministic skeletons be usable with deterministic
14697 tables.
14698
14699 With the patch, GAWK compiled by GCC without -O2 passes its test
14700 suite using a GLR parser driven by LALR tables. It fails with -O2
14701 because `struct stat' gives two different answers on my machine:
14702 88 (definition of an auto var) and later 96 (memset on this var).
14703 Hence the stack is badly corrumpted. The headers inclusion is to
14704 blame: if I move the awk.h inclusion before GLR's system header
14705 inclusion, the two struct stat have the same size.
14706
14707 * src/tables.c (pack_table): Always create conflict_table.
14708 (token_actions): Always create conflict_list.
14709 * data/glr.c (YYFLAG): Remove, unused.
14710
147112002-10-13 Akim Demaille <akim@epita.fr>
14712
14713 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
14714 (O0FLAGS): New.
14715 (VALGRIND, GXX): New.
14716 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
14717 * tests/bison.in: Run $PREBISON a pre-command.
14718 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
14719 (maintainer-check-g++): New.
14720 * Makefile.am (maintainer-check): New.
14721
147222002-10-13 Akim Demaille <akim@epita.fr>
14723
14724 * data/glr.c: Formatting changes.
14725 Tweak some trace messages to match yacc.c's.
14726
147272002-10-13 Akim Demaille <akim@epita.fr>
14728
14729 GLR parsers sometimes raise parse errors instead of performing the
14730 default reduction.
14731 Reported by Charles-Henry de Boysson.
14732
14733 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
14734 check the length of the traces when %glr.
14735 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
14736 GLR's traces.
14737 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
14738 Test GLR parsers.
14739 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
14740 (yyltype): Remove the yy prefix from the member names.
14741 (yytable): Complete its comment.
14742 (yygetLRActions): Map error action number from YYTABLE from
14743 YYTABLE_NINF to 0.
14744 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
14745 (which was a bug: it should have been YYTABEL_NINF, and yet it was
14746 not satisfying as we could compare an YYACTION computed from
14747 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
14748 only value for error actions.
14749 (yyreportParseError): In verbose parse error messages, don't issue
14750 `error' in the list of expected tokens.
14751 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
14752 next action to perform to match glr.c's decoding.
14753 (yytable): Complete its comment.
14754
147552002-10-13 Paul Eggert <eggert@twinsun.com>
14756
14757 Fix problem reported by Henrik Grubbstroem in
14758 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
14759 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
14760 because the Bison parser reads the second action before reducing
14761 the first one.
14762 * src/scan-gram.l (rule_length): New static var.
14763 Use it to keep track of the rule length in the scanner, since
14764 we can't expect the parser to be in lock-step sync with the scanner.
14765 (handle_action_dollar, handle_action_at): Use this var.
14766 * tests/actions.at (Exotic Dollars): Test for the problem.
14767
147682002-10-12 Paul Eggert <eggert@twinsun.com>
14769
14770 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
14771 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
14772 Include <sys/time.h> when checking for clock_t and struct tms.
14773 Use same include order as source.
14774 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
14775 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
14776
14777 * lib/timevar.c: Update copyright date and clarify comments.
14778 (get_time) [IN_GCC]: Keep the GCC version for reference.
14779
14780 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
14781 GCC version as of today, then merge Bison's changes.
14782 Change "GCC" to "Bison" in copyright notice. timevar.def's
14783 author is Akim, so change that too.
14784
14785 * src/reader.c (grammar_current_rule_check):
14786 Don't worry about the default action if $$ is untyped.
14787 Prevents bogus warnings reported by Jim Gifford in
14788 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
14789
14790 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
14791 * data/glr.c, data/lalr1.cc, data/yacc.c:
14792 Output token definitions before the first part of user declarations.
14793 Fixes compatibility problem reported by Jim Gifford for kbd in
14794 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
14795
147962002-10-11 Paul Eggert <eggert@twinsun.com>
14797
14798 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
14799 (yyparse): here. This undoes some of the 2002-07-25 change.
14800 Compatibility problem reported by Ralf S. Engelschall with
14801 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

148142002-10-10 Paul Eggert <eggert@twinsun.com>
14815
14816 Portability fixes for bitsets; this also avoids several GCC
14817 warnings.
14818
14819 * lib/abitset.c: Include <stddef.h>, for offsetof.
14820 * lib/lbitset.c: Likewise.
14821
14822 * lib/abitset.c (abitset_bytes): Return a size that is aligned
14823 properly for vectors of objects. Do not assume that adding a
14824 header size to a multiple of a word size yields a value that is
14825 properly aligned for the whole union.
14826 * lib/bitsetv.c (bitsetv_alloc): Likewise.
14827
14828 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
14829 unique names for structures.
14830 * lib/ebitset.c (ebitset_bytes): Likewise.
14831 * lib/lbitset.c (lbitset_bytes): Likewise.

14858 * lib/ebitset.h: Likewise.
14859 * lib/lbitset.h: Likewise.
14860
14861 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
14862 All instances of parameters of type enum bitset_opts are now of
14863 type enum_bitset_opts, to conform to the C Standard, and similarly
14864 for enum_bitset_type.
14865 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14866 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14867
14868 Do not use "struct bitset_struct" to mean different things in
14869 different modules. Not only is this confusing, it violates
14870 the C Standard, which requires that structure types in different
14871 modules must be compatible if one is to be passed to the other.
14872 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
14873 All instances of "struct bitset_struct *" replaced with "bitset".
14874 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
14875 (union bitset_union, struct abitset_struct, struct ebitset_struct,
14876 struct lbitset_struct, struct bitset_stats_struct): New types.
14877 All uses of struct bitset_struct changed to union bitset_union,
14878 etc.

14888 Do not call a function of type T using a call that assumes the
14889 function is of a different type U. Standard C requires that a
14890 function must be called with a type that is compatible with its
14891 definition.

14916
14917 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
14918 the same width as int. This reapplies a hunk of the 2002-08-12 patch
14919 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
14920 which was inadvertently undone by the 2002-09-30 patch.
14921 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
14922 the same width as int.

14931 fixes.
14932 (Symbols): Mention that any negative value returned from yylex
14933 signifies end-of-input. Warn about negative chars. Mention
14934 the portable Standard C character set.
14935
14936 The GNU coding standard says CFLAGS and YFLAGS are reserved
14937 for the installer to set.
14938 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
14939 * src/Makefile.am (AM_CFLAGS): Likewise.

15021 BITSET_SIZE_MAX): New macros.
15022 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
15023 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
15024 to BITSET_WINDEX_MAX.
15025
15026 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
15027 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

15127
15128 * doc/bison.texinfo (Conditions): Make explicit that the GPL
15129 exception applies only to yacc.c. This is a modification of a

15179 functions are not portable. Do not assume size_t is the
15180 same width as int.
15181 (yypstates): Do not assume that ptrdiff_t is the same width
15182 as int, and similarly for yyposn and YYINDEX.
15183

15222
15223 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use

15225 check for void *.
15226
15227 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
15228 size_t; the old version tried to do this but casted improperly.

15233 (_): New macro.
15234 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
15235 name locals "index", as it generates unnecessary warnings on some
15236 hosts that have an "index" function.
15237
15238 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
15239 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

15266 * src/complain.c (strerror_r): Remove decl; not needed.
15267 (strerror): Use same pattern as ../lib/error.c.

15274 to void, to avoid a GCC warning when --disable-nls is in effect.
15275

15277 to minimize the number of warnings from xgettext.
15278 (handle_action_dollar, handle_action_at): Don't use isdigit,
15279 as it mishandles negative chars and it may not work as expected
15280 outside the C locale.
15281
15282 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
15283 this is a GCC extension and is not portable to other compilers.

15286 Do not include <ctype.h>; no longer needed.

15297 exit status as failure, not just exit status 1. Sun C exits
15298 with status 2 sometimes.

15314 reduced to...
15315 (token_actions): here.
15316 * src/main.c (main): Make the parser before making the report, so
15317 that rules never reduced are computed.
15318 Call grammar_rules_never_reduced_report.
15319 * src/print.c (print_results): Report rules never reduced.
15320 * tests/conflicts.at, tests/reduce.at: Adjust.

15323
15324 Instead of attaching lookaheads and duplicating the rules being
15325 reduced by a state, attach the lookaheads to the reductions.
15326
15327 * src/state.h (state_t): Remove the `lookaheads',
15328 `lookaheads_rule' member.
15329 (reductions_t): Add a `lookaheads' member.

15341 (initialize_LA): this.
15342 (lalr_free): Adjust.
15343 * src/main.c (main): Don't free nullable and derives too early: it

15360 as they were lo longer used.
15361
153622002-08-01 Akim Demaille <akim@epita.fr>
15363
15364 * lib/timevar.c (get_time): Include children time.
15365 * src/lalr.h (LA, LArule): Don't export them: used with the
15366 state_t.
15367 * src/lalr.c (LA, LArule): Static.
15368 * src/lalr.h, src/lalr.c (lalr_free): New.

15416 (main): Replace `stage' invocations with timevar calls.
15417 * src/output.c: Insert pertinent timevar calls.
15418

15422
15423 * src/getargs.h (enum trace_e): New.
15424 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
15425 (long_options, short_options): --trace/-T takes an optional

15427 Change all the uses of trace_flag to reflect the new flags.
15428 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.

15462 by conflicts.
15463
15464 * src/LR0.c (save_reductions): Don't make the final state too
15465 different: save its reduction (accept) instead of having a state
15466 without any action (no shift or goto, no reduce).
15467 Note: the final state is now a ``regular'' state, i.e., the
15468 parsers now contain `reduce 0' as default reduction.
15469 Nevertheless, since they decide to `accept' when yystate =
15470 final_state, they still will not reduce rule 0.
15471 * src/print.c (print_actions, print_reduction): Adjust.
15472 * src/output.c (action_row): Track reduced rules.
15473 (token_actions): Report rules never reduced.

15508 * src/reduce.c (reduce_grammar): When the language is empty,
15509 complain about the start symbol, not the axiom.
15510 Use its location.
15511 * tests/reduce.at (Empty Language): New.
15512
155132002-07-26 Akim Demaille <akim@epita.fr>
15514
15515 * src/reader.h, src/reader.c (gram_error): ... can't get
15516 yycontrol without making too strong assumptions on the parser
15517 itself.
15518 * src/output.c (prepare_tokens): Use the real 0th value of
15519 token_translations instead of `0'.
15520 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
15521 visible here.
15522 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
15523 for the time being: %locations ought to provide it to yyerror.

15526
15527 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

15536 * src/nullable.c, src/output.c, src/print.c, src/reader.c
15537 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].

15540 Adjust to `derive' now containing possibly 0.
15541 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):

16596 grammar.
16597 Use more modest sizes, as for the time being the parser does not

16601 * tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the
16602 stricter %token grammar.

16685
166862002-06-10 Akim Demaille <akim@epita.fr>
16687
16688 Remove `%thong' support as it is undocumented, unused, duplicates
16689 `%token's job, and creates useless e-mail traffic with people who
16690 want to know what it is, why it is undocumented, unused, and
16691 duplicates `%token's job.
16692
16693 * src/reader.c (parse_thong_decl): Remove.

16883 Kill GCC warnings.
16884
16885 * src/reduce.c (nonterminals_reduce): Don't loop over RITEM: loop

16911 * src/LR0.c (new_state, get_state): Instead of using the global

16914 Adjust callers.
16915
169162002-05-06 Akim Demaille <akim@epita.fr>
16917
16918 * src/reader.c (packgram): No longer end `ritem' with a 0
16919 sentinel: it is not used.
16920
169212002-05-05 Akim Demaille <akim@epita.fr>
16922
16923 New experimental feature: display the lookaheads in the report and

17066 values of $$, $n and so forth, output invocation to b4_lhs_value,
17067 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
17068 Note: this patch partially drops `semantic-parser' support: it
17069 always does `rule_length - n', where semantic parsers ought to
17070 always use `-n'.
17071 * data/bison.simple, data/bison.c++ (b4_lhs_value)
17072 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

17136
17137 * data/bison.simple: Remove unnecessary commentary and white
17138 space differences from 1_29-branch.

17142 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
17143 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
17144 constructors or destructors.

17174
171752002-04-22 Akim Demaille <akim@epita.fr>
17176
17177 * src/reader.c (token_translations_init): 256 is now the default
17178 value for the error token, i.e., it will be assigned another
17179 number if the user assigned 256 to one of her tokens.
17180 (reader): Don't force 256 to error.
17181 * doc/bison.texinfo (Symbols): Adjust.
17182 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
17183 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
17184 etc. instead of 10, 20, 30 (which was used to `jump' over error

17186
171872002-04-22 Akim Demaille <akim@epita.fr>
17188
17189 Propagate more token_number_t.

17206
17207 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
17208 as Lex/Flex'.
17209 (Debugging): More details about enabling the debugging features.
17210 (Table of Symbols): Describe $$, $n, @$, and @n.
17211 Suggested by Tim Josling.
17212
172132002-04-19 Akim Demaille <akim@epita.fr>
17214
17215 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
17216

172222002-04-09 Akim Demaille <akim@epita.fr>
17223
17224 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
17225 full stderr, and strip it according to the bison options, instead
17226 of composing the error message from different bits.
17227 This makes it easier to check for several error messages.
17228 Adjust all the invocations.
17229 Add an invocation exercising the error token.
17230 Add an invocation demonstrating a stupid error message.
17231 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

17238 errtoken->number.
17239 * src/reader.c (reader): Don't specify the user token number (2)

17241 * src/gram.h (token_number_t): Move to...
17242 * src/symtab.h: here.
17243 (state_t.number): Is a token_number_t.
17244 * src/print.c, src/reader.c: Use undeftoken->number instead of
17245 hard coded 2.
17246 (Even though this 2 is not the same as above: the number of the
17247 undeftoken remains being 2, it is its user token number which
17248 might not be 2).
17249 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
17250 `user_token_number_max'.
17251 Output `undef_token_number'.
17252 * data/bison.simple, data/bison.c++: Use them.
17253 Be sure to map invalid yylex return values to
17254 `undef_token_number'. This saves us from gratuitous SEGV.

17257 (Unresolved SR Conflicts): Adjust.
17258 * tests/regression.at (Web2c Actions): Adjust.

17271
17272 * src/gram.h (item_number_t): New, the type of item numbers in
17273 RITEM. Note that it must be able to code symbol numbers as
17274 positive number, and the negation of rule numbers as negative
17275 numbers.
17276 Adjust all dependencies (pretty many).
17277 * src/reduce.c (rule): Remove this `short *' pointer: use
17278 item_number_t.
17279 * src/system.h (MINSHORT, MAXSHORT): Remove.
17280 Include `limits.h'.
17281 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
17282 (shortcpy): Remove.

17287 * tests/torture.at (Big triangle): Move the limit from 254 to
17288 500.
17289 * tests/regression.at (Web2c Actions): Ajust.
17290
17291 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
17292 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
17293 passes, but produces negative #line number, once fixed, GCC is
17294 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
17295 C), it passes.
17296 * src/state.h (state_h): Code input lines on ints, not shorts.

17422 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
17423
174242002-04-07 Akim Demaille <akim@epita.fr>

17452 items properly set, there is no need for a special case when
17453 creating `ruleset'.
17454
17455 As a result, now the rule 0, reducing to $axiom, is visible in the
17456 outputs. Adjust the test suite.

174942002-04-07 Akim Demaille <akim@epita.fr>
17495

17497 lacking `+ 1' to nrules, Bison reported as useless a token if it
17498 was used solely to set the precedence of the last rule...
17499
175002002-04-07 Akim Demaille <akim@epita.fr>
17501
17502 * data/bison.c++, data/bison.simple: Don't output the current file
17503 name in #line, to avoid useless diffs between two identical
17504 outputs under different names.

17507

17778 * src/output.c (output_skeleton): Use its result instead of the
17779 hard coded name.
17780
177812002-02-25 Akim Demaille <akim@epita.fr>
17782
17783 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
17784 Fileutils 4.1.5.
17785 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
17786 * src/output.c (output_skeleton): Use mkstemp to create a real
17787 temporary file.
17788 Move the filling of `skeleton' and its muscle to...
17789 (prepare): here.
17790 (output): Move the definition of the prologue muscle to...
17791 (prepare): here.
17792 * src/system.h (DEFAULT_TMPDIR): New.
17793
177942002-02-14 Paul Eggert <eggert@twinsun.com>
17795
17796 Remove the support for C++ namespace cleanliness; it was
17797 causing more problems than it was curing, since it didn't work
17798 properly on some nonstandard C++ compilers. This can wait
17799 for a proper C++ parser.
17800
17801 * NEWS: Document this.
17802 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
17803 of C++, as it's treated like C now.
17804 * src/bison.simple (YYSTD): Remove.
17805 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
17806 Treat C++ just like Standard C instead of trying to support
17807 namespace cleanliness.
17808
178092002-02-14 Akim Demaille <akim@epita.fr>
17810
17811 * tests/regression.at (else): Adjust to Andreas' change.
17812
178132002-02-14 Akim Demaille <akim@epita.fr>
17814
17815 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
17816
178172002-02-13 Andreas Schwab <schwab@suse.de>
17818
17819 * src/output.c (output_rule_data): Don't output NULL, it might
17820 not be defined yet.
17821
178222002-02-11 Robert Anisko <robert@lrde.epita.fr>
17823
17824 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
17825 (Copyright notice): Update.
17826
178272002-02-11 Akim Demaille <akim@epita.fr>
17828
17829 * tests/regression.at (%nonassoc and eof): Don't include
17830 nonportable headers.
17831
178322002-02-08 Robert Anisko <robert@lrde.epita.fr>
17833
17834 * data/bison.c++: Correct error recovery. Make the user able to
17835 initialize the starting location.
17836
178372002-02-07 Akim Demaille <akim@epita.fr>
17838
17839 * tests/input.at: New.
17840
178412002-02-07 Robert Anisko <robert@lrde.epita.fr>
17842
17843 * data/bison.c++: Replace some direct m4 expansions by constants. Be
17844 more consistent when naming methods and variables. Put preprocessor
17845 directives around tables only needed for debugging.
17846
178472002-02-07 Robert Anisko <robert@lrde.epita.fr>
17848
17849 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
17850 C++ parsers.
17851 (yy::b4_name::parse): Use print_.
17852
178532002-02-07 Robert Anisko <robert@lrde.epita.fr>
17854
17855 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
17856
178572002-02-07 Robert Anisko <robert@lrde.epita.fr>
17858
17859 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
17860 C++ parsers.
17861 (yy::b4_name::parse): Build verbose error messages, and use error_.
17862
178632002-02-06 Robert Anisko <robert@lrde.epita.fr>
17864
17865 * data/bison.c++: Fix m4 quoting in comments.
17866
178672002-02-06 Robert Anisko <robert@lrde.epita.fr>
17868
17869 * data/bison.c++: Adjust the parser code. Fix some muscles that were
17870 not expanded by m4.
17871
178722002-02-05 Akim Demaille <akim@epita.fr>
17873
17874 * data/bison.c++: Adjust to the M4 back end.
17875 More is certainly needed.
17876
178772002-02-05 Akim Demaille <akim@epita.fr>
17878
17879 Give a try to M4 as a back end.
17880
17881 * lib/readpipe.c: New, from wdiff.
17882 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
17883 BISON_HAIRY.
17884 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
17885 specific values. Now it is m4 that performs the lookup.
17886 * src/parse-skel.y: Remove.
17887 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
17888 * src/output.c (actions_output, guards_output)
17889 (token_definitions_output): No longer keeps track of the output
17890 line number, hence remove the second argument.
17891 (guards_output): Check against the guard member of a rule, not the
17892 action member.
17893 Adjust callers.
17894 (output_skeleton): Don't look for the skeleton location, let m4 do
17895 that.
17896 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
17897 file will be used.
17898 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
17899 (prepare): Given that for the time being changesyntax is not
17900 usable in M4, rename the muscles using `-' to `_'.
17901 Define `defines_flag', `output_parser_name' and `output_header_name'.
17902 * src/output.h (actions_output, guards_output)
17903 (token_definitions_output): Adjust prototypes.
17904 * src/scan-skel.l: Instead of scanning the skeletons, it now
17905 processes the output of m4: `__oline__' and `#output'.
17906 * data/bison.simple: Adjust to be used by M4(sugar).
17907 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
17908 to date.
17909 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
17910 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
17911 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
17912 shamelessly stolen from CVS Autoconf.
17913
179142002-02-05 Akim Demaille <akim@epita.fr>
17915
17916 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
17917 * configure.in: Check for the declarations of free and malloc.
17918 * src/muscle_tab.c: Adjust.
17919
179202002-02-05 Akim Demaille <akim@epita.fr>
17921
17922 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
17923 which have no values.
17924
179252002-02-05 Akim Demaille <akim@epita.fr>
17926
17927 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
17928 * data/: here.
17929
179302002-01-29 Paul Eggert <eggert@twinsun.com>
17931
17932 * src/bison.simple (YYSIZE_T): Do not define merely because
17933 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
17934 On some platforms, <alloca.h> does not declare YYSTD (size_t).
17935
179362002-01-27 Akim Demaille <akim@epita.fr>
17937
17938 Fix `%nonassoc and eof'.
17939
17940 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
17941 which were not properly copied! Replace
17942 memcpy (res->errs, src->errs, src->nerrs);
17943 with
17944 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
17945 !!!
17946 * tests/regression.at (%nonassoc and eof): Adjust to newest
17947 Autotest: `.' is not in the PATH.
17948
179492002-01-27 Akim Demaille <akim@epita.fr>
17950
17951 * tests/sets.at (AT_EXTRACT_SETS): New.
17952 (Nullable): Use it.
17953 (Firsts): New.
17954
179552002-01-26 Akim Demaille <akim@epita.fr>
17956
17957 * tests/actions.at, tests/calc.at, tests/headers.at,
17958 * tests/torture.at: Adjust to the newest Autotest which no longer
17959 forces `.' in the PATH.
17960
179612002-01-25 Akim Demaille <akim@epita.fr>
17962
17963 * tests/regression.at (%nonassoc and eof): New.
17964 Suggested by Robert Anisko.
17965
179662002-01-24 Akim Demaille <akim@epita.fr>
17967
17968 Bison dumps core when trying to complain about broken input files.
17969 Reported by Cris van Pelt.
17970
17971 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
17972 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
17973 into...
17974 (Invalid inputs): Strengthen: exercise parse_percent_token.
17975
179762002-01-24 Robert Anisko <robert.anisko@epita.fr>
17977
17978 * src/Makefile.am: Add bison.c++.
17979 * src/bison.c++: New skeleton.
17980
179812002-01-21 Paolo Bonzini <bonzini@gnu.org>
17982
17983 * po/it.po: New.
17984
179852002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
17986
17987 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
17988
179892002-01-20 Marc Autret <marc@gnu.org>
17990
17991 * src/files.c (compute_output_file_names): Fix
17992
179932002-01-20 Marc Autret <marc@gnu.org>
17994
17995 * tests/output.at: New test.
17996 * src/files.c (compute_base_names): Don't map extensions when
17997 the YACC flag is set, use defaults.
17998 Reported by Evgeny Stambulchik.
17999
180002002-01-20 Marc Autret <marc@gnu.org>
18001
18002 * src/system.h: Need to define __attribute__ away for non-GCC
18003 compilers as well (i.e., the vendor C compiler).
18004 Suggested by Albert Chin-A-Young.
18005
180062002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
18007
18008 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
18009 canonical definition.
18010 * src/system.h: Use the canonical definition for PARAMS (avoids
18011 a conflict with the macro from lib/hash.h).
18012
180132002-01-11 Akim Demaille <akim@epita.fr>
18014
18015 * configure.in: Use AC_FUNC_STRNLEN.
18016 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
18017
180182002-01-09 Akim Demaille <akim@epita.fr>
18019
18020 * src/files.c, src/files.h (output_infix): New.
18021 (tab_extension): Remove.
18022 (compute_base_names): Compute the former, drop the latter.
18023 * src/output.c (prepare): Insert the muscles `output-infix', and
18024 `output-suffix'.
18025 * src/parse-skel.y (string, string.1): New.
18026 (section.header): Use it.
18027 (section.yacc): Remove.
18028 (prefix): Remove too.
18029 * src/scan-skel.l: Adjust.
18030 * src/bison.simple, src/bison.hairy: Adjust.
18031
180322002-01-09 Akim Demaille <akim@epita.fr>
18033
18034 * configure.in (WERROR_CFLAGS): Compute it.
18035 * src/Makefile.am (CFLAGS): Pass it.
18036 * tests/atlocal.in (CFLAGS): Idem.
18037 * src/files.c: Fix a few warnings.
18038 (get_extension_index): Remove, unused.
18039
180402002-01-08 Akim Demaille <akim@epita.fr>
18041
18042 * src/getargs.c (AS_FILE_NAME): New.
18043 (getargs): Use it to convert DOSish file names.
18044 * src/files.c (base_name): Rename as full_base_name to avoid
18045 clashes with `base_name ()'.
18046 (filename_split): New.
18047 (compute_base_names): N-th rewrite, using filename_split.
18048
180492002-01-08 Akim Demaille <akim@epita.fr>
18050
18051 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
18052 New, stolen from the Fileutils 4.1.
18053 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
18054 * configure.in: Check for the presence of memrchr, and of its
18055 prototype.
18056
180572002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
18058
18059 * lib/hash.h (__P): Added definition for this macro.
18060 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
18061 BUILT_SOURCES, to ensure they are generated first.
18062 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
18063 %error-verbose to allow bootstrapping with bison 1.30x.
18064
180652002-01-06 Akim Demaille <akim@epita.fr>
18066
18067 * src/reader.c (parse_braces): Don't fetch the next char, the
18068 convention is to fetch on entry.
18069 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
18070 'switch' without a following semicolon.
18071 * tests/regression.at (braces parsing): New.
18072
180732002-01-06 Akim Demaille <akim@epita.fr>
18074
18075 Bison is dead wrong in its RR conflict reports.
18076
18077 * tests/torture.at (GNU Cim Grammar): New.
18078 * src/conflicts.c (count_rr_conflicts): Fix.
18079
180802002-01-06 Akim Demaille <akim@epita.fr>
18081
18082 Creating package.m4 from configure.ac causes too many problems.
18083
18084 * tests/Makefile.am (package.m4): Create it by hand,
18085 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
18086
180872002-01-06 Akim Demaille <akim@epita.fr>
18088
18089 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
18090 skeleton.h.
18091
180922002-01-04 Paul Eggert <eggert@twinsun.com>
18093
18094 * doc/bison.texinfo (Debugging):
18095 Remove YYSTDERR; it's no longer defined or used.
18096 Also, s/cstdio.h/cstdio/.
18097
180982002-01-03 Akim Demaille <akim@epita.fr>
18099
18100 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
18101
181022002-01-03 Akim Demaille <akim@epita.fr>
18103
18104 * src/parse-skel.y (process_skeleton): Don't bind the parser's
18105 tracing code to --trace, wait for a better --trace option, with
18106 args.
18107
181082002-01-03 Akim Demaille <akim@epita.fr>
18109
18110 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
18111 The ISO C++ standard is extremely clear about it: stderr is
18112 considered a macro, not a regular symbol (see table 94 `Header
18113 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
18114 Therefore std:: does not apply to it. It still does with fprintf.
18115 Also, s/cstdio.h/cstdio/.
18116
181172002-01-03 Akim Demaille <akim@epita.fr>
18118
18119 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
18120 for non system headers.
18121
181222002-01-02 Akim Demaille <akim@epita.fr>
18123
18124 Equip the skeleton chain with location tracking, runtime trace,
18125 pure parser and scanner.
18126
18127 * src/parse-skel.y: Request a pure parser, locations, and prefix
18128 renaming.
18129 (%union): Having several members with the same type does not help
18130 type mismatches, simplify.
18131 (YYPRINT, yyprint): New.
18132 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
18133 (skel_error): this.
18134 Handle locations.
18135 * src/scan-skel.l: Adjust to these changes.
18136 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
18137 (LOCATION_PRINT, skel_control_t): New.
18138
181392001-12-30 Akim Demaille <akim@epita.fr>
18140
18141 * src/parse-skel.y: Get rid of the shift/reduce conflict:
18142 replace `gb' with BLANKS.
18143 * src/scan-skel.l: Adjust.
18144
181452001-12-30 Akim Demaille <akim@epita.fr>
18146
18147 * src/system.h: We don't need nor want bcopy.
18148 Throw away MS-DOS crap: we don't need getpid.
18149 * configure.in: We don't need strndup. It was even causing
18150 problems: because Flex includes the headers *before* us,
18151 _GNU_SOURCE is not defined by config.h, and therefore strndup was
18152 not visible.
18153 * lib/xstrndup.c: New.
18154 * src/scan-skel.l: Use it.
18155 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
18156 * src/parse-skel.y: Use %directives instead of #defines.
18157
181582001-12-30 Akim Demaille <akim@epita.fr>
18159
18160 * src/skeleton.h: New.
18161 * src/output.c (output_parser, output_master_parser): Remove, dead
18162 code.
18163 * src/output.h (get_lines_number, actions_output, guards_output)
18164 (token_definitions_output): Prototype them.
18165 * src/parse-skel.y: Add the license notice.
18166 Include output.h and skeleton.h.
18167 (process_skeleton): Returns void, and takes a single parameter.
18168 * src/scan-skel.l: Add the license notice.
18169 Include skeleton.h.
18170 Don't use %option yylineno: it seems that then Flex imagines
18171 REJECT has been used, and therefore it won't reallocate its
18172 buffers (which makes no other sense to me than a bug). It results
18173 in warnings for `unused: yy_flex_realloc'.
18174
181752001-12-30 Robert Anisko <robert.anisko@epita.fr>
18176
18177 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
18178 (MUSCLE_INSERT_PREFIX): ...to there.
18179 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
18180 (MUSCLE_INSERT_PREFIX): Move from here...
18181
18182 * src/bison.hairy: Add a section directive. Put braces around muscle
18183 names. This parser skeleton is still broken, but Bison should not
18184 choke on a bad muscle 'syntax'.
18185 * src/bison.simple: Add a section directive. Put braces around muscle
18186 names.
18187
18188 * src/files.h (strsuffix, stringappend): Add declarations.
18189 (tab_extension): Add declaration.
18190 (short_base_name): Add declaration.
18191
18192 * src/files.c (strsuffix, stringappend): No longer static. These
18193 functions are used in the skeleton parser.
18194 (tab_extension): New.
18195 (compute_base_names): Use the computations done in this function
18196 to guess if the generated parsers should have '.tab' in their
18197 names.
18198 (short_base_name): No longer static.
18199
18200 * src/output.c (output_skeleton): New.
18201 (output): Disable call to output_master_parser, and give a try to
18202 a new skeleton handling system.
18203 (guards_output, actions_output): No longer static.
18204 (token_definitions_output, get_lines_number): No longer static.
18205
18206 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
18207
18208 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
18209 parse-skel.y.
18210
18211 * src/parse-skel.y: New file.
18212 * src/scan-skel.l: New file.
18213
182142001-12-29 Akim Demaille <akim@epita.fr>
18215
18216 %name-prefix is broken.
18217
18218 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
18219 Adjust all dependencies.
18220 * tests/headers.at (export YYLTYPE): Strengthen this test: use
18221 %name-prefix.
18222
18223 Renaming yylval but not yylloc is not consistent. Now we do.
18224
18225 * src/bison.simple: Prefix yylloc if used.
18226 * doc/bison.texinfo (Decl Summary): Document that.
18227
182282001-12-29 Akim Demaille <akim@epita.fr>
18229
18230 * doc/bison.texinfo: Promote `%long-directive' over
18231 `%long_directive'.
18232 Remove all references to fixed-output-files, yacc is enough.
18233
182342001-12-29 Akim Demaille <akim@epita.fr>
18235
18236 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
18237 user prologue. These are defaults.
18238 * tests/actions.at (Mid-rule actions): Make sure the user can
18239 define YYDEBUG and YYERROR_VERBOSE.
18240
182412001-12-29 Akim Demaille <akim@epita.fr>
18242
18243 * src/output.c (header_output): Don't forget to export YYLTYPE and
18244 yylloc.
18245 * tests/headers.at (export YYLTYPE): New, make sure it does.
18246 * tests/regression.at (%union and --defines, Invalid CPP headers):
18247 Move to...
18248 * tests/headers.at: here.
18249
182502001-12-29 Akim Demaille <akim@epita.fr>
18251
18252 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
18253
182542001-12-29 Akim Demaille <akim@epita.fr>
18255
18256 * tests/actions.at (Mid-rule actions): Output on a single line
18257 instead of several.
18258
182592001-12-29 Akim Demaille <akim@epita.fr>
18260
18261 * doc/bison.texinfo: Formatting changes.
18262
182632001-12-29 Akim Demaille <akim@epita.fr>
18264
18265 Don't store the token defs in a muscle, just be ready to output it
18266 on command. Now possible via `symbols'. Fixes a memory leak.
18267
18268 * src/output.c (token_definitions_output): New.
18269 (output_parser, header_output): Use it.
18270 * src/reader.c (symbols_save): Remove.
18271
182722001-12-29 Akim Demaille <akim@epita.fr>
18273
18274 * src/bison.simple: Do not provide a default for YYSTYPE and
18275 YYLTYPE before the user's prologue. Otherwise it's hardly... a
18276 default.
18277
182782001-12-29 Akim Demaille <akim@epita.fr>
18279
18280 Mid-rule actions are simply... ignored!
18281
18282 * src/reader.c (readgram): Be sure to attach mid-rule actions to
18283 the empty-rule associated to the dummy symbol, not to the host
18284 rule.
18285 * tests/actions.at (Mid-rule actions): New.
18286
182872001-12-29 Akim Demaille <akim@epita.fr>
18288
18289 Memory leak.
18290
18291 * src/reader.c (reader): Free grammar.
18292
182932001-12-29 Akim Demaille <akim@epita.fr>
18294
18295 Memory leak.
18296
18297 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
18298 since it allocates it for each state, although only one is needed.
18299 (allocate_storage): Do it here.
18300
183012001-12-29 Akim Demaille <akim@epita.fr>
18302
18303 * src/options.h, src/options.c (create_long_option_table): Rename
18304 as...
18305 (long_option_table_new): this, with a clearer prototype.
18306 (percent_table): Remove, unused,
18307 * src/getargs.c (getargs): Adjust.
18308
183092001-12-29 Akim Demaille <akim@epita.fr>
18310
18311 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
18312 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
18313 as states.
18314
183152001-12-29 Akim Demaille <akim@epita.fr>
18316
18317 * src/lalr.c (build_relations): Rename `states' as `states1'.
18318 Sorry, I don't understand exactly what it is, no better name...
18319
183202001-12-29 Akim Demaille <akim@epita.fr>
18321
18322 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
18323 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
18324 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
18325 as rules.
18326
183272001-12-29 Akim Demaille <akim@epita.fr>
18328
18329 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
18330 ago.
18331
183322001-12-29 Akim Demaille <akim@epita.fr>
18333
18334 * src/reader.c, src/reader.h (user_toknums): Remove.
18335 Adjust all users to use symbols[i]->user_token_number.
18336
183372001-12-29 Akim Demaille <akim@epita.fr>
18338
18339 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
18340 Adjust all users to use symbols[i]->prec or ->assoc.
18341
183422001-12-29 Akim Demaille <akim@epita.fr>
18343
18344 * src/reader.c, src/reader.h (tags): Remove.
18345 Adjust all users to use symbols[i]->tag.
18346
183472001-12-29 Akim Demaille <akim@epita.fr>
18348
18349 * src/gram.h, src/gram.c (symbols): New, similar to state_table
18350 and rule_table.
18351 * src/reader.c (packsymbols): Fill this table.
18352 Drop sprec.
18353 * src/conflicts.c (resolve_sr_conflict): Adjust.
18354 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
18355 single table.
18356 Use symbols[i]->tag instead of tags[i].
18357
183582001-12-29 Akim Demaille <akim@epita.fr>
18359
18360 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
18361 In addition, put a comment in there, to replace...
18362 * tests/regression.at (%union and C comments): Remove.
18363
183642001-12-29 Akim Demaille <akim@epita.fr>
18365
18366 * tests/regression.at (Web2c Actions): Blindly move the actual
18367 output as expected output. The contents *seem* right to me, but I
18368 can't pretend reading perfectly parser tables... Nonetheless, all
18369 the other tests pass correctly, the table look OK, even though the
18370 presence of `$axiom' is to be noted: AFAICS it is useless (but
18371 harmless).
18372
183732001-12-29 Akim Demaille <akim@epita.fr>
18374
18375 * src/reader.c (readgram): Don't add the rule 0 if there were no
18376 rules read. In other words, add it _after_ having performed
18377 grammar sanity checks.
18378 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
18379
183802001-12-29 Akim Demaille <akim@epita.fr>
18381
18382 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
18383 visible, and some states have now a different number.
18384
183852001-12-29 Akim Demaille <akim@epita.fr>
18386
18387 * src/reader.c (readgram): Bind the initial rule's lineno to that
18388 of the first rule.
18389 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18390 (Solved SR Conflicts): Adjust rule 0's line number.
18391
183922001-12-29 Akim Demaille <akim@epita.fr>
18393
18394 Fix the `GAWK Grammar' failure.
18395
18396 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18397 the reductions of the first state which was mistakenly confused
18398 with the final state because precisely final_state was initialized
18399 to 0.
18400 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18401 now noticed by Bison.
18402 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18403 have a reduction on $default.
18404
184052001-12-29 Akim Demaille <akim@epita.fr>
18406
18407 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18408 rule line numbers.
18409 * src/closure.c (print_closure): Likewise.
18410 * src/derives.c (print_derives): Likewise.
18411 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18412 now.
18413
184142001-12-29 Akim Demaille <akim@epita.fr>
18415
18416 * src/lalr.c (lookaheads_print): New.
18417 (lalr): Call it when --trace-flag.
18418 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18419 are dumped.
18420
184212001-12-29 Akim Demaille <akim@epita.fr>
18422
18423 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18424 when walking through ritem, even via rule->rhs.
18425 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18426 (useful_production, useless_nonterminals): Likewise.
18427 (reduce_grammar_tables): Likewise, plus update nritems.
18428 * src/nullable.c (set_nullable): Likewise.
18429 * src/lalr.c (build_relations): Likewise.
18430 * tests/sets.at (Nullable): Adjust.
18431 Fortunately, now, the $axiom is no longer nullable.
18432
184332001-12-29 Akim Demaille <akim@epita.fr>
18434
18435 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
18436 the 0-sentinel.
18437 * src/gram.c (ritem_longest_rhs): Likewise.
18438 * src/reduce.c (nonterminals_reduce): Likewise.
18439 * src/print_graph.c (print_graph): Likewise.
18440 * src/output.c (output_rule_data): Likewise.
18441 * src/nullable.c (set_nullable): Likewise.
18442
184432001-12-29 Akim Demaille <akim@epita.fr>
18444
18445 * src/output.c: Comment changes.
18446
184472001-12-27 Paul Eggert <eggert@twinsun.com>
18448
18449 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18450 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18451 Sparc, as they were causing more porting problems than the
18452 (minor) performance improvement was worth.
18453
18454 Also, catch up with 1.31's YYSTD.
18455
184562001-12-27 Akim Demaille <akim@epita.fr>
18457
18458 * src/output.c (output_gram): Rely on nritems, not the
18459 0-sentinel. See below.
18460 Use -1 as separator, not 0.
18461 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18462 Rely on -1 as separator in yyrhs, instead of 0.
18463 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18464 twice `Now at end of input', therefore there are two lines less to
18465 expect.
18466
184672001-12-27 Akim Demaille <akim@epita.fr>
18468
18469 * tests/regression.at (Unresolved SR Conflicts):
18470 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18471 below.
18472
184732001-12-27 Akim Demaille <akim@epita.fr>
18474
18475 * src/LR0.c (new_state): Recognize the final state by the fact it
18476 is reached by eoftoken.
18477 (insert_start_shifting_state, insert_eof_shifting_state)
18478 (insert_accepting_state, augment_automaton): Remove, since now
18479 these states are automatically computed from the initial state.
18480 (generate_states): Adjust.
18481 * src/print.c: When reporting a rule number to the user, substract
18482 1, so that the axiom rule is rule 0, and the first user rule is 1.
18483 * src/reduce.c: Likewise.
18484 * src/print_graph.c (print_core): For the time being, just as for
18485 the report, depend upon --trace-flags to dump the full set of
18486 items.
18487 * src/reader.c (readgram): Once the grammar read, insert the rule
18488 0: `$axiom: START-SYMBOL $'.
18489 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18490 number of the states has changed (the final state is no longer
18491 necessarily the last), catch up.
18492
184932001-12-27 Akim Demaille <akim@epita.fr>
18494
18495 Try to make the use of the eoftoken valid. Given that its value
18496 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18497 is used instead of > 0 where appropriate, (ii), depend upon nritems
18498 instead of the 0-sentinel.
18499
18500 * src/gram.h, src/gram.c (nritems): New.
18501 Expected to be duplication of nitems, but for the time being...
18502 * src/reader.c (packgram): Assert nritems and nitems are equal.
18503 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18504 * src/closure.c (print_closure, print_fderives): Likewise.
18505 * src/gram.c (ritem_print): Likewise.
18506 * src/print.c (print_core, print_grammar): Likewise.
18507 * src/print_graph.c: Likewise.
18508
185092001-12-27 Akim Demaille <akim@epita.fr>
18510
18511 * src/main.c (main): If there are complains after grammar
18512 reductions, then output the report anyway if requested, then die.
18513 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18514 * src/reader.c (eoftoken): New.
18515 (parse_token_decl): If the token being defined has value `0', it
18516 is the eoftoken.
18517 (packsymbols): No longer hack `tags' to insert `$' by hand.
18518 Be sure to preserve the value of the eoftoken.
18519 (reader): Make sure eoftoken is defined.
18520 Initialize nsyms to 0: now eoftoken is created just like the others.
18521 * src/print.c (print_grammar): Don't special case the eof token.
18522 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18523 lie anyway, albeit pleasant.
18524 * tests/calc.at: Exercise error messages with eoftoken.
18525 Change the grammar so that empty input is invalid.
18526 Adjust expectations.
18527 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18528
185292001-12-27 Akim Demaille <akim@epita.fr>
18530
18531 * configure.in: Check the protos of strchr ans strspn.
18532 Replace strchr if needed.
18533 * src/system.h: Provide the protos of strchr, strspn and memchr if
18534 missing.
18535 * lib/strchr.c: New.
18536 * src/reader.c (symbols_save): Use strchr.
18537
185382001-12-27 Akim Demaille <akim@epita.fr>
18539
18540 * src/print.c, src/print_graph.c (escape): New.
18541 Use it to quote the TAGS outputs.
18542 * src/print_graph.c (print_state): Now errors are in red, and
18543 reductions in green.
18544 Prefer high to wide: output the state number on a line of its own.
18545
185462001-12-27 Akim Demaille <akim@epita.fr>
18547
18548 * src/state.h, src/state.c (reductions_new): New.
18549 * src/LR0.c (set_state_table): Let all the states have a
18550 `reductions', even if reduced to 0.
18551 (save_reductions): Adjust.
18552 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
18553 * src/print.c (print_reductions, print_actions): Adjust.
18554 * src/output.c (action_row): Adjust.
18555
185562001-12-27 Akim Demaille <akim@epita.fr>
18557
18558 * src/state.h, src/state.c (errs_new, errs_dup): New.
18559 * src/LR0.c (set_state_table): Let all the states have an errs,
18560 even if reduced to 0.
18561 * src/print.c (print_errs, print_reductions): Adjust.
18562 * src/output.c (output_actions, action_row): Adjust.
18563 * src/conflicts.c (resolve_sr_conflict): Adjust.
18564
185652001-12-27 Akim Demaille <akim@epita.fr>
18566
18567 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
18568
185692001-12-27 Akim Demaille <akim@epita.fr>
18570
18571 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
18572 * src/print.c: here.
18573 (lookaheadset, shiftset): New, used as additional storage by
18574 print_reductions.
18575 (print_results): Adjust.
18576 (print_shifts, print_gotos, print_errs): New, extracted from...
18577 (print_actions): here.
18578 * src/print_graph.c (print_actions): Remove dead code.
18579
185802001-12-27 Akim Demaille <akim@epita.fr>
18581
18582 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
18583 `$n' and `@n'.
18584
185852001-12-27 Akim Demaille <akim@epita.fr>
18586
18587 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
18588 (build_relations): Adjust.
18589
185902001-12-27 Akim Demaille <akim@epita.fr>
18591
18592 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
18593 duplication.
18594
185952001-12-27 Akim Demaille <akim@epita.fr>
18596
18597 * src/reader.c (packgram): Catch nitems overflows.
18598
185992001-12-27 Akim Demaille <akim@epita.fr>
18600
18601 * src/files.c, src/files.h (guard_obstack): Remove.
18602 * src/output.c (output): Adjust.
18603 * src/reader.c (parse_braces): New, factoring...
18604 (copy_action, copy_guard): these two which are renamed as...
18605 (parse_action, parse_guard): these.
18606 As a voluntary consequence, using braces around guards is now
18607 mandatory.
18608
186092001-12-27 Akim Demaille <akim@epita.fr>
18610
18611 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
18612 * src/reader.c (symbol_list): `guard' and `guard_line' are new
18613 members.
18614 (symbol_list_new): Adjust.
18615 (copy_action): action_line is the first line, not the last.
18616 (copy_guard): Just as for actions, store the `action' only, not
18617 the switch/case/break flesh.
18618 Don't parse the user action that might follow the guard, let...
18619 (readgram): do it, i.e., now, there can be an action after a
18620 guard.
18621 In other words the guard is just explicitly optional.
18622 (packgram): Adjust.
18623 * src/output.c (guards_output): New.
18624 (output_parser): Call it when needed.
18625 (output): Also free the guard and attrs obstacks.
18626 * src/files.c, src/files.h (obstack_save): Remove.
18627 (output_files): Remove.
18628 As a result, if one needs the former `.act' file, using an
18629 appropriate skeleton which requires actions and guards is now
18630 required.
18631 * src/main.c (main): Adjust.
18632 * tests/semantic.at: New.
18633 * tests/regression.at: Use `input.y' as input file name.
18634 Avoid 8+3 problems by requiring input.c when the test needs the
18635 parser.
18636
186372001-12-27 Akim Demaille <akim@epita.fr>
18638
18639 * src/reader.c (symbol_list_new): Be sure to initialize all the
18640 fields.
18641
186422001-12-27 Akim Demaille <akim@epita.fr>
18643
18644 All the hacks using a final pseudo state are now useless.
18645
18646 * src/LR0.c (set_state_table): state_table holds exactly nstates.
18647 * src/lalr.c (nLA): New.
18648 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
18649 instead of lookaheadsp from the pseudo state (nstate + 1).
18650
186512001-12-27 Akim Demaille <akim@epita.fr>
18652
18653 * src/output.c (action_row, token_actions): Use a state_t instead
18654 of a integer, and nlookaheads instead of the following state's
18655 lookaheadsp.
18656
186572001-12-27 Akim Demaille <akim@epita.fr>
18658
18659 * src/conflicts.c (log_resolution, flush_shift)
18660 (resolve_sr_conflict, set_conflicts, solve_conflicts)
18661 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
18662 (conflicts_print, print_reductions): Use a state_t instead of an
18663 integer when referring to a state.
18664 As much as possible, depend upon nlookaheads, instead of the
18665 `lookaheadsp' member of the following state (since lookaheads of
18666 successive states are successive, the difference between state n + 1
18667 and n served as the number of lookaheads for state n).
18668 * src/lalr.c (add_lookback_edge): Likewise.
18669 * src/print.c (print_core, print_actions, print_state)
18670 (print_results): Likewise.
18671 * src/print_graph.c (print_core, print_actions, print_state)
18672 (print_graph): Likewise.
18673 * src/conflicts.h: Adjust.
18674
186752001-12-27 Akim Demaille <akim@epita.fr>
18676
18677 * src/bison.hairy: Formatting/comment changes.
18678 ANSIfy.
18679 Remove `register' indications.
18680 Add plenty of `static'.
18681
186822001-12-27 Akim Demaille <akim@epita.fr>
18683
18684 * src/output.c (prepare): Drop the muscle `ntbase' which
18685 duplicates ntokens.
18686 * src/bison.simple: Formatting/comment changes.
18687 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
18688 is an undocumented synonym.
18689
186902001-12-22 Akim Demaille <akim@epita.fr>
18691
18692 * src/output.c (output_table_data): Change the prototype to use
18693 `int' for array ranges: some invocations do pass an int, not a
18694 short.
18695 Reported by Wayne Green.
18696
186972001-12-22 Akim Demaille <akim@epita.fr>
18698
18699 Some actions of web2c.y are improperly triggered.
18700 Reported by Mike Castle.
18701
18702 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
18703 * tests/regression.at (Web2c): Rename as...
18704 (Web2c Report): this.
18705 (Web2c Actions): New.
18706
187072001-12-22 Akim Demaille <akim@epita.fr>
18708
18709 Reductions in web2c.y are improperly reported.
18710 Reported by Mike Castle.
18711
18712 * src/conflicts.c (print_reductions): Fix.
18713 * tests/regression.at (Web2c): New.
18714
187152001-12-18 Akim Demaille <akim@epita.fr>
18716
18717 Some host fail on `assert (!"foo")', which expands to
18718 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
18719 Reported by Nelson Beebee.
18720
18721 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
18722 `#define it_succeeded 0' and `assert (it_succeeded)'.
18723
187242001-12-17 Marc Autret <autret_m@epita.fr>
18725
18726 * src/bison.simple: Don't hard code the skeleton line and filename.
18727 * src/output.c (output_parser): Rename 'line' as 'output_line'.
18728 New line counter 'skeleton_line' (skeleton-line muscle).
18729
187302001-12-17 Paul Eggert <eggert@twinsun.com>
18731
18732 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
18733 YYDEBUG must be defined to a nonzero value.
18734
18735 * src/bison.simple (yytname): Do not assume that the user defines
18736 YYDEBUG to a properly parenthesized expression.
18737
187382001-12-17 Akim Demaille <akim@epita.fr>
18739
18740 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
18741 nlookaheads is a new member.
18742 Adjust all users.
18743 * src/lalr.h (nlookaheads): Remove this orphan declaration.
18744 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
18745 state.
18746
187472001-12-17 Akim Demaille <akim@epita.fr>
18748
18749 * src/files.h, src/files.c (open_files, close_files): Remove.
18750 * src/main.c (main): Don't open/close files, nor invoke lex_free,
18751 let...
18752 * src/reader.c (reader): Do it.
18753
187542001-12-17 Akim Demaille <akim@epita.fr>
18755
18756 * src/conflicts.c (print_reductions): Formatting changes.
18757
187582001-12-17 Akim Demaille <akim@epita.fr>
18759
18760 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
18761 (flush_reduce): New.
18762 (resolve_sr_conflict): Adjust.
18763
187642001-12-17 Akim Demaille <akim@epita.fr>
18765
18766 * src/output.c (output_obstack): Be static and rename as...
18767 (format_obstack): this, to avoid any confusion with files.c's
18768 output_obstack.
18769 * src/reader.h (muscle_obstack): Move to...
18770 * src/output.h: here, since it's defined in output.c.
18771
187722001-12-17 Akim Demaille <akim@epita.fr>
18773
18774 * src/output.c (action_row, save_column, default_goto)
18775 (sort_actions, matching_state, pack_vector): Better variable
18776 locality.
18777
187782001-12-17 Akim Demaille <akim@epita.fr>
18779
18780 * src/output.c: Various formatting changes.
18781
187822001-12-17 Akim Demaille <akim@epita.fr>
18783
18784 * src/files.c (output_files): Free the output_obstack.
18785 * src/main.c (main): Call print and print_graph conditionally.
18786 * src/print.c (print): Work unconditionally.
18787 * src/print_graph.c (print_graph): Work unconditionally.
18788 * src/conflicts.c (log_resolution): Output only if verbose_flag.
18789
187902001-12-16 Marc Autret <autret_m@epita.fr>
18791
18792 * src/output.c (actions_output): Fix. When we use %no-lines,
18793 there is one less line per action.
18794
187952001-12-16 Marc Autret <autret_m@epita.fr>
18796
18797 * src/bison.simple: Remove a useless #line directive.
18798 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18799 * src/output.c (get_lines_number): New.
18800 (output_parser): Adjust, now takes care about the lines of a
18801 output muscles.
18802 Fix line numbering.
18803 (actions_output): Computes the number of lines taken by actions.
18804 (output_master_parser): Insert new skeleton which is the name of
18805 the output parser file name.
18806
188072001-12-15 Marc Autret <autret_m@epita.fr>
18808
18809 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
18810
188112001-12-15 Marc Autret <autret_m@epita.fr>
18812
18813 * src/output.c (output_gram): Keep track of the hairy one.
18814
188152001-12-15 Akim Demaille <akim@epita.fr>
18816
18817 Make `make distcheck' work.
18818
18819 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
18820 system.h which uses libgettext.h.
18821
188222001-12-15 Akim Demaille <akim@epita.fr>
18823
18824 * src/nullable.c (set_nullable): Useless rules must be skipped,
18825 otherwise, since we range over their symbols, we might look at a
18826 nonterminal which no longer ``exists'', i.e., it is not counted in
18827 `nvars', hence we overflow our arrays.
18828
188292001-12-15 Akim Demaille <akim@epita.fr>
18830
18831 The header can also be produced directly, without any obstack!
18832 Yahoo!
18833
18834 * src/files.c, src/files.h (defines_obstack): Remove.
18835 (compute_header_macro): Global.
18836 (defines_obstack_save): Remove.
18837 * src/reader.c (parse_union_decl): No longer output to
18838 defines_obstack: its content can be found in the `stype' muscle
18839 anyway.
18840 (output_token_translations): Merge into...
18841 (symbols_output): this.
18842 Rename as...
18843 (symbols_save): this.
18844 (reader): Adjust.
18845 * src/output.c (header_output): New.
18846 (output): Call it.
18847
188482001-12-15 Akim Demaille <akim@epita.fr>
18849
18850 * src/reader.c (parse_union_decl): Instead of handling two obstack
18851 simultaneously, use one to define the `stype' muscle, and use the
18852 value of the latter to fill defines_obstack.
18853 (copy_comment): Remove.
18854 (copy_comment2): Work for a single obstack.
18855 Rename as...
18856 (copy_comment): this.
18857
188582001-12-15 Akim Demaille <akim@epita.fr>
18859
18860 * src/lex.c, src/lex.h (xgetc): No longer static.
18861 * src/reader.c (parse_union_decl): Revamp.
18862
188632001-12-15 Akim Demaille <akim@epita.fr>
18864
18865 Still making progress in separating Bison into (i) input, (ii)
18866 process, (iii) output: now we can directly output the parser file
18867 without using table_obstack at all.
18868
18869 * src/files.c, src/files.h (table_obstack): Bye bye.
18870 (parser_file_name): New.
18871 * src/files.c (compute_output_file_names): Compute it.
18872 * src/output.c (actions_output, output_parser)
18873 (output_master_parser): To a file instead of an obstack.
18874
188752001-12-15 Akim Demaille <akim@epita.fr>
18876
18877 Attach actions to rules, instead of pre-outputting them to
18878 actions_obstack.
18879
18880 * src/gram.h (rule_t): action and action_line are new members.
18881 * src/reader.c (symbol_list): Likewise.
18882 (copy_action): Save the actions within the rule.
18883 (packgram): Save them in rule_table.
18884 * src/output.c (actions_output): New.
18885 (output_parser): Use it on `%%actions'.
18886 (output_rule_data): Don't free rule_table.
18887 (output): Do it.
18888 (prepare): Don't save the `action' muscle.
18889 * src/bison.simple: s/%%action/%%actions/.
18890
188912001-12-15 Akim Demaille <akim@epita.fr>
18892
18893 * src/reader.c (copy_action): When --yacc, don't append a `;'
18894 to the user action: let it fail if lacking.
18895 Suggested by Arnold Robbins and Tom Tromey.
18896
188972001-12-14 Akim Demaille <akim@epita.fr>
18898
18899 * src/lex.c (literalchar): Simply return the char you decoded, non
18900 longer mess around with obstacks and int pointers.
18901 Adjust all callers.
18902
189032001-12-14 Akim Demaille <akim@epita.fr>
18904
18905 * src/lex.c (literalchar): Don't escape the special characters,
18906 just decode them, and keep them as char (before, eol was output as
18907 the 2 char string `\n' etc.).
18908 * src/output.c (output_rule_data): Use quotearg to output the
18909 token strings.
18910
189112001-12-13 Paul Eggert <eggert@twinsun.com>
18912
18913 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
18914 Do not infringe on the global user namespace when using C++.
18915 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
18916 All uses of `fprintf' and `stderr' changed.
18917
18918 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
18919
189202001-12-13 Akim Demaille <akim@epita.fr>
18921
18922 The computation of nullable is broken: it doesn't handle empty
18923 RHS's properly.
18924
18925 * tests/torture.at (GNU AWK Grammar): New.
18926 * tests/sets.at (Nullable): New.
18927 * src/nullable.c (set_nullable): Instead of blindly looping over
18928 `ritems', loop over the rules, and then over their rhs's.
18929
18930 Work around Autotest bugs.
18931
18932 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
18933 frame, because Autotest understand lines starting with a `+' as
18934 traces from the shell. Then, they are not processed properly.
18935 Admittedly an Autotest bug, but we don't have time to wait for
18936 Autotest to catch up.
18937 * tests/regression.at (Broken Closure): Adjust to the new table
18938 frames.
18939 Move to...
18940 * tests/sets.at: here.
18941
189422001-12-13 Akim Demaille <akim@epita.fr>
18943
18944 * src/closure.c (closure): Use nrules instead of playing tricks
18945 with BITS_PER_WORD.
18946
189472001-12-13 Akim Demaille <akim@epita.fr>
18948
18949 * src/print.c (print_actions): Output the handling of `$' as the
18950 traces do: shifting the token EOF. Before EOF was treated as a
18951 nonterminal.
18952 * tests/regression.at: Adjust some tests.
18953 * src/print_graph.c (print_core): Complete the set of items via
18954 closure. The next-to-final and final states are still unsatisfying,
18955 but that's to be addressed elsewhere.
18956 No longer output the rule numbers, but do output the state number.
18957 A single loop for the shifts + gotos is enough, but picked a
18958 distinct color for each.
18959 (print_graph): Initialize and finalize closure.
18960
189612001-12-13 Akim Demaille <akim@epita.fr>
18962
18963 * src/reader.c (readgram): Remove dead code, an strip useless
18964 braces.
18965 (get_type): Remove, unused.
18966
189672001-12-12 Akim Demaille <akim@epita.fr>
18968
18969 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
18970 on that of lib/error.c.
18971
189722001-12-12 Akim Demaille <akim@epita.fr>
18973
18974 Some hosts don't like `/' in includes.
18975
18976 * src/system.h: Include libgettext.h without qualifying the path.
18977 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18978 $(top_srcdir).
18979
189802001-12-11 Marc Autret <autret_m@epita.fr>
18981
18982 * src/output.c (output_parser): Remove useless muscle.
18983
189842001-12-11 Marc Autret <autret_m@epita.fr>
18985
18986 * src/bison.simple: Remove #line just before %%epilogue. It
18987 is now handled in ...
18988 * src/reader.c (read_additionnal_code): Add the output of a
18989 #line for the epilogue.
18990
189912001-12-10 Marc Autret <autret_m@epita.fr>
18992
18993 * src/reader.c (copy_definition): Re-use CPP-outed code which
18994 replace precedent remove.
18995 * src/bison.simple: Remove #line before %%prologue because
18996 %%input-line is wrong at this time.
18997
189982001-12-10 Marc Autret <autret_m@epita.fr>
18999
19000 * src/reader.c (symbols_output): Clean up.
19001 * src/output.c (output_gram, output): Clean up.
19002
190032001-12-10 Akim Demaille <akim@epita.fr>
19004
19005 * src/lalr.c (initialize_lookaheads): New. Extracted from...
19006 * src/LR0.c (set_state_table): here.
19007 * src/lalr.c (lalr): Call it.
19008
190092001-12-10 Akim Demaille <akim@epita.fr>
19010
19011 * src/state.h (shifts): Remove the `number' member: shifts are
19012 attached to state, hence no longer need to be labelled with a
19013 state number.
19014
190152001-12-10 Akim Demaille <akim@epita.fr>
19016
19017 Now that states have a complete set of members, the linked list of
19018 shifts is useless: just fill directly the state's shifts member.
19019
19020 * src/state.h (shifts): Remove the `next' member.
19021 * src/LR0.c (first_state, last_state): Remove.
19022 Adjust the callers.
19023 (augment_automaton): Don't look for the shifts that must be added
19024 a shift on EOF: it is those of the state we looked for! But now,
19025 since shifts are attached, it is no longer needed to looking
19026 merely by its id: its number.
19027
190282001-12-10 Akim Demaille <akim@epita.fr>
19029
19030 * src/LR0.c (augment_automaton): Better variable locality.
19031 Remove an impossible branch: if there is a state corresponding to
19032 the start symbol being shifted, then there is shift for the start
19033 symbol from the initial state.
19034
190352001-12-10 Akim Demaille <akim@epita.fr>
19036
19037 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
19038 only when appropriate: when insert_start_shifting_state' is not
19039 invoked.
19040 * tests/regression.at (Rule Line Numbers): Adjust.
19041
190422001-12-10 Akim Demaille <akim@epita.fr>
19043
19044 * src/LR0.c (augment_automaton): Now that all states have shifts,
19045 merge the two cases addition shifts to the initial state.
19046
190472001-12-10 Akim Demaille <akim@epita.fr>
19048
19049 * src/lalr.c (set_state_table): Move to...
19050 * src/LR0.c: here.
19051 * src/lalr.c (lalr): Don't call it...
19052 * src/LR0.c (generate_states): do it.
19053 * src/LR0.h (first_state): Remove, only the table is used.
19054
190552001-12-10 Akim Demaille <akim@epita.fr>
19056
19057 * src/LR0.h (first_shift, first_reduction): Remove.
19058 * src/lalr.c: Don't use first_shift: find shifts through the
19059 states.
19060
190612001-12-10 Akim Demaille <akim@epita.fr>
19062
19063 * src/LR0.c: Attach shifts to states as soon as they are
19064 computed.
19065 * src/lalr.c (set_state_table): Instead of assigning shifts to
19066 state, just assert that the mapping was properly done.
19067
190682001-12-10 Akim Demaille <akim@epita.fr>
19069
19070 * src/LR0.c (insert_start_shift): Rename as...
19071 (insert_start_shifting_state): this.
19072 (insert_eof_shifting_state, insert_accepting_state): New.
19073 (augment_automaton): Adjust.
19074 Better locality of the variables.
19075 When looking if the start_symbol is shifted from the initial
19076 state, using `while (... symbol != start_symbol ...)' sounds
19077 better than `while (... symbol < start_symbol ...)': If fail
19078 to see how the order between symbols could be relevant!
19079
190802001-12-10 Akim Demaille <akim@epita.fr>
19081
19082 * src/getargs.h: Don't declare `spec_name_prefix' and
19083 `spec_file_prefix', declared by src/files.h.
19084 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
19085 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
19086 * src/output.c (prepare): Adjust.
19087 * src/reader.c (symbols_output): Likewise.
19088 * src/vmsgetargs.c: Vaguely adjust, but who cares?
19089
190902001-12-10 Akim Demaille <akim@epita.fr>
19091
19092 * src/muscle_tab.c (muscle_init): NULL is a better default than
19093 `"0"'.
19094
190952001-12-10 Akim Demaille <akim@epita.fr>
19096
19097 * src/reader.c (reader): Calling symbols_output once is enough.
19098
190992001-12-10 Akim Demaille <akim@epita.fr>
19100
19101 Now that states have a complete set of members, the linked list of
19102 reductions is useless: just fill directly the state's reductions
19103 member.
19104
19105 * src/state.h (struct reductions): Remove member `number' and
19106 `next'.
19107 * src/LR0.c (first_reduction, last_reduction): Remove.
19108 (save_reductions): Don't link the new reductions, store them in
19109 this_state.
19110 * src/lalr.c (set_state_table): No need to attach reductions to
19111 states, it's already done.
19112 * src/output.c (output_actions): No longer free the shifts, then
19113 the reductions, then the states: free all the states and their
19114 members.
19115
191162001-12-10 Akim Demaille <akim@epita.fr>
19117
19118 * src/options.c (OPTN, DRTV, BOTH): New.
19119 (option_table): Use them.
19120
19121 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
19122 the job of system.h.
19123 * src/options.c: Don't include stdio.h and xalloc.h for the same
19124 reasons.
19125
191262001-12-10 Akim Demaille <akim@epita.fr>
19127
19128 * src/output.c (output, prepare): Make sure the values of the
19129 muscles `action' and `prologue' are 0-terminated.
19130
191312001-12-10 Akim Demaille <akim@epita.fr>
19132
19133 Clean up GCC warnings.
19134
19135 * src/reader.c (copy_action): `buf' is not used.
19136 (parse_skel_decl): Be static.
19137 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
19138 * src/options.h (create_long_option_table): Have a real prototype.
19139 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
19140 (hash_delete_at): Return const void *.
19141 Adjust casts to preserve the const.
19142
191432001-12-10 Akim Demaille <akim@epita.fr>
19144
19145 * configure.in: Require 2.52g.
19146 M4 is not needed, but AUTOM4TE is.
19147 * m4/m4.m4: Remove.
19148 * tests/Makefile.am: Adjust.
19149
191502001-12-10 Akim Demaille <akim@epita.fr>
19151
19152 One structure for states is enough, even though theoretically
19153 there are LR(0) states and LALR(1) states.
19154
19155 * src/lalr.h (state_t): Remove.
19156 (state_table): Be state_t **, not state_t *.
19157 * src/state.h (core, CORE_ALLOC): Rename as...
19158 (state_t, STATE_ALLOC): this.
19159 Add the LALR(1) members: shifts, reductions, errs.
19160 * src/LR0.c (state_table): Rename as...
19161 (state_hash): this, to avoid name clashes with the global
19162 `state_table'.
19163 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
19164 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
19165
191662001-12-10 Akim Demaille <akim@epita.fr>
19167
19168 Bison dumps core on bash.y.
19169 Reported by Pascal Bart.
19170
19171 * src/warshall.c (bitmatrix_print): New.
19172 (TC): Use it.
19173 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
19174 j must be the outer loop.
19175 * tests/regression.at (Broken Closure): New.
19176
191772001-12-05 Akim Demaille <akim@epita.fr>
19178
19179 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
19180 its argument.
19181 Reported by Peter Hamorsky.
19182
191832001-12-05 Akim Demaille <akim@epita.fr>
19184
19185 * src/conflicts.c (err_table): Remove.
19186 (resolve_sr_conflict): Adjust.
19187 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
19188 Rename as...
19189 (state_t.reductions, state_t.shifts): this.
19190
191912001-12-05 Akim Demaille <akim@epita.fr>
19192
19193 * src/reduce.c (reduce_grammar_tables): No longer disable the
19194 removal of useless rules via CPP but via `if (0)', so that the
19195 compiler still check the code is valid.
19196 For instance, it should have noticed `rline' no longer exists: use
19197 the `line' member of rule_t.
19198 * src/gram.c (dummy, rline): Remove, unused.
19199
192002001-12-05 Akim Demaille <akim@epita.fr>
19201
19202 * src/output.c (pack_vector): Use assert, not berror.
19203 * src/main.c (berror): Remove, unused.
19204
192052001-12-05 Akim Demaille <akim@epita.fr>
19206
19207 New experimental feature: if --verbose --trace output all the
19208 items of a state, not only its kernel.
19209
19210 * src/print.c (print_core): If `trace_flag', then invoke closure
19211 before outputting the items of the state (print_core is no longer
19212 a correct name them).
19213 (print_results): Invoke new_closure/free_closure if needed.
19214
192152001-12-05 Akim Demaille <akim@epita.fr>
19216
19217 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
19218 * src/closure.c, src/closure.h (itemsetsize): Rename as...
19219 (nitemset): for consistency with the rest of the project.
19220
192212001-12-05 Akim Demaille <akim@epita.fr>
19222
19223 * src/closure.c (print_closure): Improve.
19224 (closure): Use it for printing input and output.
19225
192262001-12-05 Akim Demaille <akim@epita.fr>
19227
19228 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
19229 indexed by nonterminals.
19230
192312001-12-05 Akim Demaille <akim@epita.fr>
19232
19233 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
19234 what it was!).
19235 * src/warshall.h: Remove accidental duplication of the content.
19236
192372001-12-05 Akim Demaille <akim@epita.fr>
19238
19239 * src/closure.c (set_fderives): De-obfuscate.
19240
192412001-12-05 Akim Demaille <akim@epita.fr>
19242
19243 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
19244
192452001-12-05 Akim Demaille <akim@epita.fr>
19246
19247 * src/closure.c (set_firsts): De-obfuscate.
19248
192492001-12-05 Akim Demaille <akim@epita.fr>
19250
19251 * src/output.c (action_row): De-obfuscate
19252 using the good o' techniques: arrays not pointers, variable
19253 locality, BITISSET, RESETBIT etc.
19254
192552001-12-05 Akim Demaille <akim@epita.fr>
19256
19257 Pessimize the code to simplify it: from now on, all the states
19258 have a valid SHIFTS, which NSHIFTS is possibly 0.
19259
19260 * src/LR0.c (shifts_new): Be global and move to..
19261 * src/state.c, src/state.h: here.
19262 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
19263 * src/print_graph: Adjust.
19264
192652001-12-05 Akim Demaille <akim@epita.fr>
19266
19267 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
19268 * src/conflicts.c: Use it.
19269 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
19270 incorrectly ``simplified''.
19271
192722001-12-05 Akim Demaille <akim@epita.fr>
19273
19274 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
19275 using the good o' techniques: arrays not pointers, variable
19276 locality, BITISSET, RESETBIT etc.
19277
192782001-12-05 Akim Demaille <akim@epita.fr>
19279
19280 * src/state.h (SHIFT_SYMBOL): New.
19281 * src/conflicts.c: Use it to deobfuscate.
19282
192832001-12-05 Akim Demaille <akim@epita.fr>
19284
19285 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
19286 (print_reductions): De-obfuscate using the good o' techniques:
19287 arrays not pointers, variable locality, BITISSET.
19288
192892001-12-05 Akim Demaille <akim@epita.fr>
19290
19291 * src/conflicts.c (print_reductions): Arrays, not pointers.
19292 Use BITISSET.
19293
192942001-12-05 Akim Demaille <akim@epita.fr>
19295
19296 * src/conflicts.c (print_reductions): Pessimize, but clarify.
19297
192982001-12-05 Akim Demaille <akim@epita.fr>
19299
19300 * src/conflicts.c (print_reductions): Improve variable locality.
19301
193022001-12-05 Akim Demaille <akim@epita.fr>
19303
19304 * src/conflicts.c (print_reductions): Pessimize, but clarify.
19305
193062001-12-05 Akim Demaille <akim@epita.fr>
19307
19308 * src/conflicts.c (print_reductions): Improve variable locality.
19309
193102001-12-05 Akim Demaille <akim@epita.fr>
19311
19312 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
19313 * src/lalr.c: Use them.
19314
193152001-12-05 Akim Demaille <akim@epita.fr>
19316
19317 * src/LR0.c (augment_automaton): Formatting changes.
19318 Better variable locality.
19319
193202001-12-05 Akim Demaille <akim@epita.fr>
19321
19322 * src/lalr.c (matrix_print): New.
19323 (transpose): Use it.
19324 Use arrays instead of pointers.
19325
193262001-12-05 Akim Demaille <akim@epita.fr>
19327
19328 * src/lalr.c (maxrhs): Move to...
19329 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
19330 * src/lalr.c (build_relations): Adjust.
19331
193322001-12-05 Akim Demaille <akim@epita.fr>
19333
19334 * src/lalr.c (transpose): Free the memory allocated to the
19335 argument, as it is replaced by the results by the unique caller.
19336 (build_relations): Merely invoke transpose: it handles the memory
19337 deallocation.
19338 Improve variable locality.
19339 Avoid variables used as mere abbreviations.
19340 (compute_lookaheads): Use arrays instead of pointers.
19341
193422001-12-05 Akim Demaille <akim@epita.fr>
19343
19344 * src/lalr.c (initialize_F): Improve variable locality.
19345 Avoid variables used as mere abbreviations.
19346
193472001-12-05 Akim Demaille <akim@epita.fr>
19348
19349 * src/derives.c (print_derives): Display the ruleno.
19350 * src/lalr.c (initialize_F, transpose): Better variable locality
19351 to improve readability.
19352 Avoid variables used as mere abbreviations.
19353
193542001-12-05 Akim Demaille <akim@epita.fr>
19355
19356 * src/lalr.c (traverse): Use arrays instead of pointers.
19357
193582001-12-05 Akim Demaille <akim@epita.fr>
19359
19360 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
19361 the handling of squeue.
19362 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19363
193642001-12-05 Akim Demaille <akim@epita.fr>
19365
19366 Because useless nonterminals are now kept alive (instead of being
19367 `destroyed'), we now sometimes examine them, and store information
19368 related to them. Hence we need to know their number, and adjust
19369 memory allocations.
19370
19371 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19372 static.
19373 * src/LR0.c (allocate_itemsets): The memory allocated to
19374 `symbol_count' was used for two different purpose: once to count
19375 the number of occurrences of each symbol, and later reassigned to
19376 `shift_symbol', containing the symbol that can be shifted from a
19377 given state.
19378 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19379 only, and...
19380 (new_itemsets): Allocate `shift_symbol' here.
19381 (allocate_itemsets): symbol_count includes useless nonterminals.
19382 Make room for them.
19383 (free_storage): Use `free', not `XFREE', for pointers that cannot
19384 be null.
19385
193862001-12-05 Akim Demaille <akim@epita.fr>
19387
19388 * src/nullable.c (set_nullable): Deobfuscate the handling of
19389 ritem.
19390 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19391
193922001-12-05 Akim Demaille <akim@epita.fr>
19393
19394 * src/gram.c, src/gram.h (ritem_print): New.
19395 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19396 (This useless function was defined only to work around VMS linkers
19397 that can't handle compilation units with variables only).
19398 * src/reduce.c (dump_grammar): Use it to trace the construction of
19399 ritem.
19400
194012001-12-04 Paul Eggert <eggert@twinsun.com>
19402
19403 * src/bison.simple (union yyalloc): Change member names
19404 to be the same as the stack names.
19405 (yyparse): yyptr is now union yyalloc *, not char *.
19406 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19407 and may generate better code on some machines.
19408 (yystpcpy): Use prototype if __STDC__ is defined, not just
19409 if __cplusplus is defined.
19410
194112001-11-30 Akim Demaille <akim@epita.fr>
19412
19413 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19414 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
19415 Gettext doesn't compile cleanly, and dies with -Werror.
19416 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
19417 Include WARNING_CFLAGS here.
19418 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
19419 before being defined.
19420
194212001-11-27 Paul Eggert <eggert@twinsun.com>
19422
19423 * lib/quotearg.h (quotearg_n, quotearg_n_style):
19424 First arg is int, not unsigned.
19425 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
19426 (SIZE_MAX, UINT_MAX): New macros.
19427 (quotearg_n_options): Abort if N is negative.
19428 Avoid overflow check on hosts where size_t is 64 bits and int
19429 is 32 bits, as overflow is impossible there.
19430 Fix off-by-one typo that caused unnecessary reallocation.
19431
194322001-11-29 Paul Eggert <eggert@twinsun.com>
19433
19434 Name space cleanup in generated parser.
19435
19436 * doc/bison.texinfo (Bison Parser): Discuss system headers
19437 and their effect on the user name space.
19438
19439 * src/bison.simple:
19440 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19441 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19442 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19443
19444 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
19445 on user names when possible.
19446
19447 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
19448 Simplify test for whather <alloca.h> exists.
19449
19450 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
19451
19452 (<stdio.h>): Include if YYDEBUG.
19453
19454 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
19455 ! defined (yyoverflow) && ! defined (yymemcpy).
19456
19457 (yymemcpy, yyparse): Rename local variables as needed so that
19458 they all begin with 'yy'.
19459
19460 (yystrlen, yystpcpy): New functions.
19461
19462 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
19463 All uses changed.
19464
19465 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
19466 instead of relying on string.h functions. Use YYSTACK_ALLOC
19467 and YYSTACK_FREE instead of malloc and free.
19468
194692001-11-30 Akim Demaille <akim@epita.fr>
19470
19471 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
19472 before their first uses.
19473 (YYBISON, YYPURE): Move to the top of the output.
19474
194752001-11-30 Akim Demaille <akim@epita.fr>
19476
19477 * tests/reduce.at (Useless Nonterminals): Fix.
19478
194792001-11-30 Akim Demaille <akim@epita.fr>
19480
19481 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
19482 if body instead of `;' to pacify GCC's warnings.
19483
194842001-11-30 Akim Demaille <akim@epita.fr>
19485
19486 Instead of mapping the LHS of unused rules to -1, keep the LHS
19487 valid, but flag the rules as invalid.
19488
19489 * src/gram.h (rule_t): `useful' is a new member.
19490 * src/print.c (print_grammar): Adjust.
19491 * src/derives.c (set_derives): Likewise.
19492 * src/reader.c (packgram, reduce_output): Likewise.
19493 * src/reduce.c (reduce_grammar_tables): Likewise.
19494 * tests/reduce.at (Underivable Rules, Useless Rules): New.
19495
194962001-11-30 Akim Demaille <akim@epita.fr>
19497
19498 * src/reduce.c (reduce_output): Formatting changes.
19499 * src/print.c (print_results, print_grammar): Likewise.
19500 * tests/regression.at (Rule Line Numbers)
19501 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
19502
195032001-11-30 Akim Demaille <akim@epita.fr>
19504
19505 * src/reduce.c (nonterminals_reduce): Instead of throwing away
19506 useless nonterminals, move them at the end of the symbol arrays.

19522 New macros.
19523 (union yyalloc): New type.
19524 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
19525 an arbitrary restriction on hosts where size_t is wider than int.
19526
19527 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19528 a parser stack overflow. Allocate just one block of memory for all
19529 three stacks, instead of allocating three blocks; this typically is
19530 faster and reduces fragmentation.
19531
19532 Do not limit the number of items in the stack to a value that fits
19533 in 'int', as this is an arbitrary limit on hosts with 64-bit
19534 size_t and 32-bit int.

19961 * tests/calc.at, tests/output.at, tests/regression.at,
19962 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
19963 now the tests are run in private dirs, therefore AC_CLEANUP and

19966 use abs. path to find config.h.
19967 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

19990 * src/lex.c (parse_percent_token): Replace equal_offset with
19991 arg_offset.
19992 arg is const.

20921 obstack. It was done too late here.

21338

21346 New, from fileutils 4.0.37.
21347 * configure.in: Require Autoconf 2.49c. I took some time before
21348 making this decision. This is the only way out for portability
21349 issues in Bison, it would mean way too much duplicate effort to
21350 import in Bison features implemented in 2.49c since 2.13.
21351 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

213682001-01-19 Akim Demaille <akim@epita.fr>
21369
21370 * src/lex.h: Rename all the tokens:
21371 s/\bENDFILE\b/tok_eof/g;
21372 s/\bIDENTIFIER\b/tok_identifier/g;
21373 etc.

21387 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

21390 instead of returning a token.
21391 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
21392 * src/reader.c (read_declarations): Adjust.
21393 * src/files.c (open_files): Don't call `compute_base_names', don't
21394 compute `attrsfile' since they depend upon data which might be
21395 *in* the input file now.
21396 (output_files): Do it here.
21397 * src/output.c (output_headers): Document the fact that this patch
21398 introduces a guaranteed SEGV for semantic parsers.

214252000-12-20 Akim Demaille <akim@epita.fr>
21426
21427 * src/files.c (open_files): Actually the `.output' file is based

21430
214312000-12-20 Akim Demaille <akim@epita.fr>

21457 (stringappend): Be just like strcat but allocate.

21462 * tests/suite.at (Checking output file names): New test.
21463

215002000-12-19 Akim Demaille <akim@epita.fr>
21501
21502 * src/files.c (open_files): Yipee! We no longer need all the code
21503 looking for `/tmp' since we have no tmp file.
21504
215052000-12-19 Akim Demaille <akim@epita.fr>
21506

21536 prevents type checking.
21537 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

21587 Qualify it `const'.
21588 (obstack_copy, obstack_copy0): Rename the second argument as

21694
21695 * src/reader.c (copy_comment2): Expect the input stream to be on
21696 the `/' which is suspected to open a comment, instead of being
21697 called after `//' or `/*' was read.
21698 (copy_comment, copy_definition, parse_union_decl, copy_action)
21699 (copy_guard): Adjust.
21700

21729 When a literal string is used to define two different tokens,
21730 `bison -v' segfaults.
21731 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
21732

21742 From Neil Booth.
21743
217442000-10-02 Paul Eggert <eggert@twinsun.com>
21745
21746 * bison.s1 (yyparse): Assign the default value
21747 unconditionally, to avoid a GCC warning and make the parser a
21748 tad smaller.
21749
217502000-10-02 Akim Demaille <akim@epita.fr>
21751
21752 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
21753 options.
21754
217552000-10-02 Akim Demaille <akim@epita.fr>
21756
21757 * src/derives.c, src/print.c, src/reduce.c: To ease the
21758 translation, move some `\n' out of the translated strings.
21759
217602000-10-02 Akim Demaille <akim@epita.fr>
21761
21762 The location tracking mechanism is precious for parse error
21763 messages. Nevertheless, it is enabled only when `@n' is used in
21764 the grammar, which is a different issue (you can use it in error
21765 message, but not in the grammar per se). Therefore, there should
21766 be another means to enable it.
21767
21768 * src/getargs.c (getargs): Support `--locations'.
21769 (usage): Report it.
21770 * src/getargs.h (locationsflag): Export it.
21771 * src/lex.c (percent_table): Support `%locations'.
21772 * src/reader.c (yylsp_needed): Remove this variable, now replaced
21773 with `locationsflag'.
21774 * doc/bison.texinfo: Document `--locations' and `%locations'.
21775 Sort the options.
21776 * tests/calc.m4: Test it.
21777
21778 For regularity of the names, replace each
21779 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
21780 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
21781 In addition replace each `flag' with `_flag'.
21782
217832000-10-02 Akim Demaille <akim@epita.fr>
21784
21785 Also test parse error messages, including with YYERROR_VERBOSE.
21786
21787 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
21788 associative).
21789 Use it to check the computations.
21790 Use it to check `nonassoc' is honored.
21791 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
21792 `--yyerror-verbose'.
21793 (_AT_CHECK_CALC): Adjust to this option.
21794 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
21795
217962000-10-02 Akim Demaille <akim@epita.fr>
21797
21798 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21799 the latter demonstrates a flaw in the handling of non debugging
21800 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21801 was used in order to simplify:
21802
21803 #if YYDEBUG
21804 if (yydebug)
21805 {
21806 ...
21807 }
21808 #endif
21809
21810 into
21811
21812 if (yydebug)
21813 {
21814 ...
21815 }
21816
21817 unfortunately this leads to a CPP conflict when
21818 `--name-prefix=foo' is used since it produces `#define yydebug
21819 foodebug'.
21820
21821 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
21822 (YYDPRINTF): New macro.
21823 Spread its use.
21824 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
21825 the bison options.
21826 Also test `--verbose', `--defines' and `--name-prefix'.
21827
218282000-10-02 Akim Demaille <akim@epita.fr>
21829
21830 Improve the readability of the produced parsers.
21831
21832 * src/bison.s1: Formatting changes.
21833 Improve the comment related to the `$' mark.
21834 (yydefault): Don't fall through to `yyresume': `goto' there.
21835 * src/output.c (output_parser): When the `$' is met, skip the end
21836 of its line.
21837 New variable, `number_of_dollar_signs', to check there's exactly
21838 one `$' in the parser skeleton.
21839
218402000-10-02 Akim Demaille <akim@epita.fr>
21841
21842 * lib/xstrdup.c: New file, from the fileutils.
21843 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
21844 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
21845 instead of strlen + xmalloc + strcpy.
21846 * src/symtab.c (copys): Remove, use xstrdup instead.
21847
218482000-10-02 Akim Demaille <akim@epita.fr>
21849
21850 * src/gram.h (associativity): New enum type which replaces the
21851 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
21852 `right_assoc', `left_assoc' and `non_assoc'.
21853 Adjust all dependencies.
21854 * src/reader.c: Formatting changes.
21855 (LTYPESTR): Don't define it, use it as a literal in
21856 `reader_output_yylsp'.
21857 * src/symtab.h (symbol_class): New enum type which replaces the
21858 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
21859 `sunknown', `stoken and `snterm'.
21860
218612000-10-02 Akim Demaille <akim@epita.fr>
21862
21863 * src/getargs.c (fixed_outfiles): Rename as...
21864 (yaccflag): for consistency and accuracy.
21865 Adjust dependencies.
21866
218672000-10-02 Akim Demaille <akim@epita.fr>
21868
21869 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21870 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21871 difficult and introduced a lot of core dump. It turns out that
21872 Bison used an implementation of `xmalloc' based on `calloc', and
21873 at various places it does depend upon the initialization to 0. I
21874 have not tried to isolate the pertinent places, and all the former
21875 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21876 someone should address this issue.
21877
21878 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
21879 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

21923 * src/conflicts.h: New file.
21924 Propagate its inclusion.

21975 output_short_table.
21976
219772000-10-02 Akim Demaille <akim@epita.fr>
21978
21979 `user_toknums' is output as a `short[]' in `output.c', while it is
21980 defined as a `int[]' in `reader.c'. For consistency with the
21981 other output tables, `user_toknums' is now defined as a table of
21982 shorts.
21983
21984 * src/reader.c (user_toknums): Be a short table instead of an int
21985 table.
21986 Adjust dependencies.

22164 * Makefile.am (SUBDIRS): Adjust.
22165 * configure.in: Adjust.

22245
22246 Change the handling of @s so that they behave exactly like $s.
22247 There is now a pseudo variable @$ (readble and writable), location
22248 of the lhs of the rule (by default ranging from the location of
22249 the first symbol of the rhs, to the location of the last symbol,
22250 or, if the rhs is empty, YYLLOC).

22254 (yyparse): When providing a default semantic action, provide a

22285 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
22286 One `#if YYDEBUG' remains, since it uses variables which are
22287 defined only if `YYDEBUG != 0'.
22288
222892000-03-16 Akim Demaille <akim@epita.fr>
22290

22327 * m4/Makefile.am (EXTRA_DIST): New variable.

23013 way to specify the flags -n, -l, and -r. Also added hooks for
