5 2009-05-19 Joel E. Denny <jdenny@ces.clemson.edu>
7 Handle a trailing `:' in a user-supplied C++ namespace better.
8 * data/c++.m4 (b4_namespace_close): Don't let it be printed
9 among the closing braces here. This fix might make the
10 generated code easier to debug, but otherwise it should be
11 insignificant because a trailing `:' is a C++ error already.
13 2009-05-19 Akim Demaille <demaille@gostai.com>
15 remove useless variable.
16 * src/getargs.c (skeleton_arg): Remove now useless variable.

84 * src/files.c (tr): Move to...
85 * src/getargs.c, src/getargs.h (tr): ... here because I can't
86 think of a better place to expose it. My logic is that, for all

523 ERROR_VERBOSE being defined as false or true.
524 * data/bison.m4 (b4_percent_define_if_define): Instead of relying
525 on b4_percent_define_ifdef, for does not check the defined value,

542 and discussed again starting at
543 <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
544 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
545 because location information is bogus.
546 Use angle brackets to delimit fake file name because square brackets
547 look like underexpanded m4. Choose a better fake file name.
548 Use negative line numbers.
549 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
550 * src/location.c (location_print): If line for a boundary is negative,
551 only print that boundary's file name.

595 * data/location.cc: Update copyright years.
596 (Position::operator==): Use parens to make precedence explicit.
597 Compare lines and columns first, as they are more likely to be

621 Use locations in the variant example.
622 Yes, this obfuscates the point of this example, variants only.

741 There is no good reason to keep it private (and it is convenient
742 to use it from the scanner for instance). It is already public in

852 Fix portability issue in the test suite.
853 * tests/local.at (AT_MATCHES_CHECK): New.
854 Based on Perl instead of Sed. Sed has too many portability
855 pitfalls, not ever Sed is GNU Sed.

887 Makefile properly updates atconfig when needed.
889 2008-12-07 Di-an Jan <dianj@freeshell.org>
891 Implement the FIXME that ends an user action with a semicolon
892 if it seems necessary.
893 * src/scan-code.l (flex rules section): Flag cpp directive from
894 any `#' to the first unescaped end-of-line. Semicolon is not
895 needed after `;', `{', '}', or cpp directives and is needed after
896 any other token (whitespaces and comments have no effect).
897 * tests/actions.at (Fix user actions without a trailing semicolon):

925 since some of them contain unbalanced ')'.
927 2008-12-01 Akim Demaille <demaille@gostai.com>
929 Use b4_symbol for printers and destructors everywhere.
930 * data/bison.m4 (b4_symbol_action_location): New.

934 * data/glr.cc: Adjust.
935 * data/lalr1.java: Adjust the %destructor sanity check.
936 * src/output.c (symbol_code_props_output): Remove, we no longer

939 2008-12-01 Akim Demaille <demaille@gostai.com>
942 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use

951 (b4_type_foreach): Move to...
952 * data/bison.m4: Here.
953 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
954 b4_symbol_value_template instead of b4_symbol_value.
956 2008-12-01 Akim Demaille <demaille@gostai.com>
958 b4_symbol/type_foreach.
959 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
962 2008-12-01 Akim Demaille <demaille@gostai.com>
964 Use the symbol properties to output the printer/destructor for lalr1.cc.
965 Instead of defining complex list of tuples to define various
966 properties of the symbols, we now prefer to define symbols as
967 "structs" in m4: using the symbol key (its number), and the
968 property name, b4_symbol gives it value. Use this to handle
969 destructors and printers.
971 * src/output.c (CODE_PROP): New.
972 (prepare_symbol_definitions): Use it to define the printer and
973 destructor related attributes of the symbols.

988 Remove spurious empty line before syncline.
989 * data/bison.m4 (b4_syncline): Don't output an empty line before
992 2008-11-26 Akim Demaille <demaille@gostai.com>
994 Convert lib/Makefile.am into lib/local.mk.
995 The real problem is rather gnulib.mk, which itself is extracted
996 from a Makefile.am that gnulib expects to the "recursive". The
997 tool prefix-gnulib-mk converts such a gnulib.mk to be
998 non-recursive. Also, some AC_SUBST variables need to be adjusted.
1000 * etc/prefix-gnulib-mk: New.
1001 * bootstrap (slurp): Use it to convert further gnulib.mk.
1002 No longer try to avoid re-creation of lib/gnulib.mk as the changes

1019 Use b4_parser_tables_define in glr.cc.
1020 * data/glr.c: Use b4_parser_tables_define instead of defining the
1021 (deterministic integral) tables by hand.
1023 2008-11-26 Akim Demaille <demaille@gostai.com>
1025 Use b4_parser_tables_define in Java.

1027 (b4_typed_parser_table_define): this, for consistency.
1028 Accept a comment as $4.

1048 (yyrline_): Move the comment where it is actually used.
1049 * data/yacc.c: Adjust.
1050 (yyrline): Use b4_integral_parser_table_define.
1052 2008-11-26 Akim Demaille <demaille@gostai.com>
1055 * src/parse-gram.h, src/parse-gram.c: Regen.
1057 2008-11-26 Akim Demaille <demaille@gostai.com>

1071 2008-11-26 Akim Demaille <demaille@gostai.com>
1073 Get rid of (yy)rhs and (yy)prhs.
1074 These tables are no longer needed in the parsers, and they don't seem to
1075 be useful. They are not documented either.
1077 * src/output.c (prepare_rules): Get rid of rhs and prhs.
1078 Adjust the computation of (yy)r2.
1080 2008-11-26 Akim Demaille <demaille@gostai.com>
1082 Rule length is unsigned.
1083 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
1085 2008-11-26 Akim Demaille <demaille@gostai.com>
1087 Get rid of lalr1-split.cc.
1088 It was no longer maintainer.
1090 * data/lalr1-split.cc: Remove.
1091 * etc/bench.pl.in (bench_fusion_parser): Remove.
1094 2008-11-26 Akim Demaille <demaille@gostai.com>
1096 Use yy* consistently.
1097 * data/glr.c: Now that yyrhs no longer exists as a global
1098 variable, rename local "rhs" variables into "yyrhs" for
1101 2008-11-25 Akim Demaille <demaille@gostai.com>
1103 Get rid of yyrhs and yyprhs in glr.c.
1104 * data/glr.c (yyrhs, yyprhs): Remove.
1105 Instead, use the state stack and yystos.
1107 2008-11-25 Akim Demaille <demaille@gostai.com>
1110 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
1111 as an Autotest keyword.
1113 2008-11-25 Akim Demaille <demaille@gostai.com>
1115 Prefer TESTSUITE_FLAGS.
1116 TESTSUITEFLAGS is barely readable.
1118 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
1119 for backward compatibility.
1120 Use the former instead of the latter.
1122 2008-11-25 Akim Demaille <demaille@gostai.com>
1124 Get rid of yyrhs and yyprhs in larl1.java.
1125 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
1126 (yy_reduce_print): Rather, use yystos_ and the state stack.
1128 2008-11-25 Akim Demaille <demaille@gostai.com>
1132 2008-11-25 Akim Demaille <demaille@gostai.com>
1134 Get rid of yyrhs and yyprhs in yacc.c.
1135 They were used to get the symbol types, given a rule number, when
1136 displaying the top of the stack before a reduction. But the
1137 symbol type is available from the state stack. This has two be
1138 benefits: two tables less in the parser (making it smaller), and a
1139 more consistent use of the three stacks which will help to fuse
1142 * data/yacc.c (yyprhs, yyrhs): Remove.
1143 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
1144 (yy_reduce_print): Take yyssp as argument.
1145 Use it, together with yystos, to get the symbol type.
1146 * tests/regression.at (Web2c Report): Remove these tables from the
1149 2008-11-25 Akim Demaille <demaille@gostai.com>
1152 The point is to factor the generation of the tables across skeletons.
1153 This is language dependant.
1155 * data/c.m4 (b4_comment_): New.
1156 Should be usable to define how to generate tables independently of
1158 (b4_c_comment): New.
1159 (b4_comment): Bounce to b4_c_comment.
1160 Now support $2 = [PREFIX] for indentation.
1161 * data/lalr1.cc (b4_table_declare): Don't output a comment if
1162 there is no comment.
1163 Indent it properly when there is one.
1164 Output the ending semicolon.
1165 (b4_table_define): Space changes.
1166 Output the ending semicolon.
1167 (b4_tables_map): New.
1168 Use it twice instead of declaring and defining the (integral)
1171 2008-11-25 Akim Demaille <demaille@gostai.com>
1174 * data/lalr1.cc (b4_table_declare): New.
1175 Use it to declare the tables defined with b4_table_define.
1176 (b4_table_define): Declare a third arg to match b4_table_declare
1178 Move all the comments around invocations of b4_table_define into
1179 the invocations itselves.
1180 Move things around to have the order for declarations and

1186 * data/lalr1.java: here.
1188 2008-11-25 Akim Demaille <demaille@gostai.com>
1190 b4_args is more general than only C++.
1191 * data/lalr1.cc (b4_args, _b4_args): Move to...
1192 * data/bison.m4: here.
1194 2008-11-21 Di-an Jan <dianj@freeshell.org>
1196 Implement no-XXX arguments for --warnings, --report, --trace.
1197 * src/getargs.c (flags_argmatch): Handles no-XXX.
1198 Fix typo in doxygen comment.
1200 2008-11-21 Akim Demaille <demaille@gostai.com>
1202 Display the changes in cross-options.texi.
1203 * build-aux/cross-options.pl ($sep): New, to separate items.
1204 * doc/local.mk ($(CROSS_OPTIONS_TEXI)): Use diff to display the
1207 2008-11-20 Di-an Jan <dianj@freeshell.org>
1209 Improves options in the manual.
1210 * doc/bison.texinfo (-g, -x): Add space before argument.
1211 (Option Cross Key): Implement FIXME: listing directives also.
1212 * build-aux/cross-options.pl: Read from <STDIN> rather than <>.
1213 (Short Option): Special case -d. Put arguments inside @option.
1214 (Bison Directive): Add column, automatically extracted from
1215 src/scan-gram.l (actual name passed as the first argument)
1216 with special case for %define.
1217 * doc/local.mk (doc/cross-options.texi): Pass src/scan-gram.l
1218 to build-aux/cross-options.pl.

1224 Fix unexpanded macros in GLR defines file.
1225 Reported by Csaba Raduly at
1226 <http://lists.gnu.org/archive/html/bug-bison/2008-11/msg00048.html>.
1227 * THANKS (Csaba Raduly): Add.
1228 * data/glr.c: Fix overquoting on b4_prefix for yylval and yylloc.
1229 * tests/calc.at (_AT_DATA_CALC_Y): If %defines is specified, generate
1230 lexer in a separate module that includes the defines file.

1237 (AT_DATA_GRAMMAR_PROLOGUE): Use AT_DATA_SOURCE_PROLOGUE.
1238 (AT_DATA_SOURCE): New.
1239 (AT_FULL_COMPILE): Extend to support an additional source file.
1241 2008-11-18 Akim Demaille <demaille@gostai.com>

1253 Use b4_subtract where possible.
1254 * data/lalr1.cc (b4_subtract): Move to...
1255 * data/bison.m4: here.
1256 * data/glr.c (b4_rhs_data): Use it.
1257 * data/yacc.c (b4_rhs_value, b4_rhs_location): Use it.
1259 2008-11-18 Akim Demaille <demaille@gostai.com>
1261 Remove incorrect mode specification.
1262 * data/glr.cc: Don't pretend it's C code.
1264 2008-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
1266 Simplify last patch slightly.
1267 * src/getargs.c (getargs): Here.

1283 * doc/bison.texinfo: Synchronize ``Detail Node Listing''.
1284 Align menus. Adjust word wrapping. Use node names for menu names.
1285 (Examples): Don't abbreviate node names.
1286 (LocalWords): Remove abbreviations.
1287 (Copying): Make description a sentence.
1288 (Java Action Features): Remove period to match the rest of menu.
1290 2008-11-17 Di-an Jan <dianj@freeshell.org>
1292 Handles several --enable-gcc-warnings.
1293 * src/getargs.c (command_line_location): Set parameters to void.
1294 * src/output.c (symbol_type_name_cmp): Make static.
1295 (symbols_by_type_name): Set parameters to void.
1296 (symbol_definitions_output): Remove unused parameter. Rename as...
1297 (prepare_symbol_definitions): this.
1298 (muscles_output): Move symbol_definitions_output to...
1299 (output): here as prepare_symbol_definitions.
1300 * tests/c++.at (AT_CHECK_VARIANTS): Remove unused parameters of main.
1301 (AT_CHECK_NAMESPACE): Make unused parameter lloc unnamed.
1303 2008-11-17 Di-an Jan <dianj@freeshell.org>
1305 * tests/c++.at (AT_CHECK_VARIANTS): Fixes tests 198-202.
1306 Use AT_DATA_GRAMMAR instead of AT_DATA for compiled tests.
1308 2008-11-16 Akim Demaille <demaille@gostai.com>
1310 Add missing $(EXEEXT).
1311 * doc/local.mk ($(CROSS_OPTIONS_TEXI)): The target is
1312 "src/bison$(EXEEXT)".
1313 Reported by Di-an Jan.

1326 Remove duplicate header inclusion.
1329 2008-11-15 Akim Demaille <demaille@gostai.com>
1331 * src/parse-gram.h, src/parse-gram.c: Regen.
1333 2008-11-15 Akim Demaille <demaille@gostai.com>
1335 Support parametric types.
1337 There are two issues to handle: first scanning nested angle
1338 bracket pairs to support types such as std::pair< std::string,
1339 std::list<std::string> > >.
1341 Another issue is to address idiosyncracies of C++: do not glue two
1342 closing angle brackets together (otherwise it's operator>>), and
1343 avoid sticking blindly a TYPE to the opening <, as it can result
1344 in '<:' which is a digraph for '['.
1346 * src/scan-gram.l (brace_level): Rename as...
1349 Implement support for complex tags.
1352 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
1353 (b4_symbol_variant): Leave space around types as parameters.
1354 * examples/variant.yy: Use nested template types and leading ::.
1355 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
1357 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
1358 * tests/c++.at: Test parametric types.
1360 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
1363 This is not sufficient, but we test at least that the make_SYMBOL
1364 interface is not affected by token.prefix. A more general test
1365 will be implemented when the support of token.prefix is generalized
1368 * tests/c++.at: One more variant test, using token.prefix.
1370 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
1372 Test the make_TOKEN interface.
1373 * tests/c++.at (AT_CHECK_VARIANTS): Require and use locations.
1374 Factor the common code in yylex.
1375 Use it to test "%define lex_symbol".

1395 Update variant.yy to newest interface.
1396 * examples/variant.yy: Define lex_symbol.
1399 2008-11-15 Akim Demaille <demaille@gostai.com>
1401 Don't use locations in variant.yy.
1402 * examples/variant.yy: Adjust to not using locations.
1404 2008-11-15 Akim Demaille <demaille@gostai.com>
1407 * data/local.mk, etc/local.mk, examples/local.mk: Use Automake
1408 comments for the license.
1410 2008-11-15 Akim Demaille <demaille@gostai.com>
1412 Remove tests/Makefile.am.

1440 2008-11-15 Akim Demaille <demaille@gostai.com>
1442 Move sc_tight_scope into maint.mk.
1443 It does not work, and I don't know how it was supposed to work: it
1444 seems to be looking for sources in the build tree. I just moved
1445 it at a better place, fixing it is still required.
1447 * src/local.mk (echo): Remove.

1463 (AM_CPPFLAGS): Find find in builddir/src.
1464 (YACC): Move the flags into...
1466 * maint.mk (sc_tight_scope): Disable.
1467 It used to bounce to the version in src/Makefile.am which is now
1468 part of this very Makefile.
1469 * Makefile.am, configure.ac: Adjust.
1470 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
1471 include "..." to find files "here": we are no longer in src/, so
1472 qualify the includes with src/.
1473 * doc/Makefile.am (PREPATH): No longer include the top_builddir

1502 Remove examples/local.mk.
1503 examples/calc++/Makefile.am might be interesting to keep as is, since
1504 it is an example in itself.

1520 * Makefile.am, configure.ac: Adjust.
1522 2008-11-15 Akim Demaille <demaille@gostai.com>
1524 Provide convenience constructors for locations and positions.
1525 * data/location.cc (position::position): Accept file, line and
1526 column as arguments with default values.
1527 Always qualify initial line and column literals as unsigned.
1528 (location::location): Provide convenience constructors.
1530 2008-11-15 Akim Demaille <demaille@gostai.com>
1532 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
1534 Using template buys us nothing, and makes it uselessly complex to
1535 construct a symbol. Besides, it could not be generalized to other
1536 languages, while make_FOO would work in C/Java etc.
1538 * data/lalr1.cc (b4_symbol_): New.
1539 (b4_symbol): Use it.
1540 (b4_symbol_constructor_declaration_)
1541 (b4_symbol_constructor_definition_): Instead of generating
1542 specializations of an overloaded template function, just generate
1543 several functions whose names are forged from the token names
1544 without the token.prefix.
1545 (b4_symbol_constructor_declarations): Generate them for all the
1546 symbols, not just by class of symbol type, now that instead of
1547 specializing a function template by the token, we generate a
1548 function named after the token.
1549 (b4_symbol_constructor_specialization_)
1550 (b4_symbol_constructor_specializations): Remove.
1551 * etc/bench.pl.in: Adjust to this new API.
1553 2008-11-13 Akim Demaille <demaille@gostai.com>
1555 %define token.prefix.
1556 Provide a means to add a prefix to the name of the tokens as
1557 output in the generated files. Because of name clashes, it is
1558 good to have such a prefix such as TOK_ that protects from names
1559 such as EOF, FILE etc. But it clutters the grammar itself.
1561 * data/bison.m4 (token.prefix): Empty by default.
1562 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
1563 * data/lalr1.cc (b4_symbol): Ditto.
1565 2008-11-13 Akim Demaille <demaille@gostai.com>
1567 Compute at M4 time some of the subtractions.
1568 * data/lalr1.cc (b4_subtract): New.
1569 (b4_rhs_data): Use it.
1571 2008-11-13 Akim Demaille <demaille@gostai.com>
1574 This allows the user to get the type of a token returned by yylex.
1576 * data/lalr1.cc (symbol::token): New.
1577 (yytoknum_): Define when %define lex_symbol, independently of
1579 (yytoken_number_): Move into...
1580 (symbol::token): here, since that's the only use.
1581 The other one is YYPRINT which was not officially supported
1582 by lalr1.cc, and anyway it did not work since YYPRINT uses this
1583 array under a different name (yytoknum).
1585 2008-11-13 Akim Demaille <demaille@gostai.com>
1588 * TODO (YYERRCODE): Mention the case of $undef.
1590 2008-11-13 Akim Demaille <demaille@gostai.com>
1593 * TODO (YYPRINT): New.
1595 2008-11-13 Akim Demaille <demaille@gostai.com>
1598 * data/lalr1.cc, data/yacc.c: Fix the description of the
1599 yytranslate and yytoknum tables.
1601 2008-11-13 Akim Demaille <demaille@gostai.com>
1603 Define make_symbol in the header.
1604 To reach good performances these functions should be inlined (yet
1605 this is to measure precisely). To this end they must be available
1608 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
1609 location_type with the class name.
1610 Since will now be output in the header, declare "inline".
1611 No longer use b4_symbol_constructor_specializations, but
1612 b4_symbol_constructor_definitions in the header.
1613 Don't call it in the *.cc file.
1615 2008-11-13 Akim Demaille <demaille@gostai.com>
1617 Define yytranslate in the header for lex_symbol.
1618 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
1619 into the header file when using %define lex_symbol.
1620 (yytranslate_): Declare inline.
1622 2008-11-13 Akim Demaille <demaille@gostai.com>
1624 Define the constructors of symbol_type in
1625 b4_symbol_constructor_definitions.
1626 The constructors are called by the make_symbol functions, which a
1627 forthcoming patch will move elsewhere. Hence the interest of
1628 putting them together.
1630 The stack_symbol_type does not need to be moved, it is used only
1633 * data/lalr1.cc: Move symbol_type and symbol_base_type
1634 constructors into...
1635 (b4_symbol_constructor_definitions): here.
1638 2008-11-13 Akim Demaille <demaille@gostai.com>
1640 Make it easier to move the definition of yytranslate_.
1641 Forthcoming changes will make it possible to use yytranslate_
1642 from outside the parser implementation file.
1644 * data/lalr1.cc (b4_yytranslate_definition): New.
1647 2008-11-13 Akim Demaille <demaille@gostai.com>
1649 Remove useless class specification.
1650 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
1651 to refer to the class name to use a type defined by the class for
1652 arguments of member functions.
1654 2008-11-13 Akim Demaille <demaille@gostai.com>
1656 Finer input type for yytranslate.
1657 This patch is debatable: the tradition expects yylex to return an int
1658 which happens to correspond to token_number (which is an enum). This
1659 allows for instance to return characters (such as '*' etc.). But this
1660 goes against the stronger typing I am trying to have with the new
1661 lex interface which return a symbol_type. So in this case, feed
1662 yytranslate_ with a token_type.
1664 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
1665 expect a token_type.
1667 2008-11-13 Akim Demaille <demaille@gostai.com>
1669 Honor lex-params in %define lex_symbol mode.
1670 * data/lalr1.cc: Use b4_lex_param.
1672 2008-11-13 Akim Demaille <demaille@gostai.com>
1675 * src/output.c (symbol_definitions_output): Rename symbol
1676 attributes type_name and has_type_name as type and has_type.
1677 * data/lalr1.cc: Adjust uses.
1679 2008-11-13 Akim Demaille <demaille@gostai.com>
1681 Use b4_type_names for the union type.
1682 The union used to compute the size of the variant used to iterate
1683 over the type of all the symbols, with a lot of redundancy. Now
1684 iterate over the lists of symbols having the same type-name.
1686 * data/lalr1.cc (b4_char_sizeof_): New.
1687 (b4_char_sizeof): Use it.
1688 Adjust to be called with a list of numbers instead of a single
1690 Adjust its caller for new-line issues.
1692 2008-11-13 Akim Demaille <demaille@gostai.com>
1694 Define the "identifier" of a symbol.
1695 Symbols may have several string representations, for instance if
1696 they have an alias. What I call its "id" is a string that can be
1697 used as an identifier. May not exist.
1699 Currently the symbols which have the "tag_is_id" flag set are
1700 those that don't have an alias. Look harder for the id.
1702 * src/output.c (is_identifier): Move to...
1703 * src/symtab.c (is_identifier): here.
1704 * src/symtab.h, src/symtab.c (symbol_id_get): New.
1705 * src/output.c (symbol_definitions_output): Use it to define "id"
1707 Remove the definition of "tag_is_id".
1708 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
1709 "tag_is_id" were used to produce code.
1710 We still use "tag" for documentation.
1712 2008-11-11 Akim Demaille <demaille@gostai.com>
1714 Locations are no longer required by lalr1.cc.
1715 * data/lalr1.cc (_b4_args, b4_args): New.
1716 Adjust all uses of locations to make them optional.
1717 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
1718 (AT_CHECK_NAMESPACE): Check the use of locations.
1719 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
1720 without locations with lalr1.cc.
1722 * tests/output.at: Check lalr1.cc with and without location
1724 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
1725 Don't use locations.
1727 2008-11-11 Akim Demaille <demaille@gostai.com>
1730 * tests/local.at (AT_FULL_COMPILE): New.
1731 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
1733 2008-11-11 Akim Demaille <demaille@gostai.com>
1735 Support parens in calc++.
1736 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
1737 * examples/calc++/test (run): Check the expected output.
1741 2008-11-11 Akim Demaille <demaille@gostai.com>
1743 Simplify lalr1.cc since %defines is mandatory.
1744 * data/lalr1.cc: Remove useless calls to b4_defines_if.
1746 2008-11-11 Akim Demaille <demaille@gostai.com>
1749 * TODO (yysyntax_error): New item.
1751 2008-11-11 Akim Demaille <demaille@gostai.com>
1754 * data/lalr1.cc: Use b4_error_verbose_if instead of #if
1757 2008-11-11 Akim Demaille <demaille@gostai.com>
1759 Support i18n of the parse error messages.
1760 * TODO (lalr1.cc/I18n): Remove.
1761 * data/lalr1.cc (yysyntax_error_): Support the translation of the
1762 error messages, as done in yacc.c.
1763 Stay within the yy* pseudo namespace.
1765 2008-11-11 Akim Demaille <demaille@gostai.com>
1768 * TODO (single stack, yysyntax_error): New.
1770 2008-11-11 Akim Demaille <demaille@gostai.com>
1772 Make it possible to return a symbol_type from yylex.
1773 * data/lalr1.cc (b4_lex_symbol_if): New.
1774 (parse): When lex_symbol is defined, expected yylex to return the
1776 * etc/bench.pl.in (generate_grammar_list): Extend to support this
1778 (bench_variant_parser): Exercise it.
1780 2008-11-11 Akim Demaille <demaille@gostai.com>
1782 Remove useless bench case.
1783 * etc/bench.pl.in (bench_variant_parser): VARIANT_DESTROY is
1786 2008-11-11 Akim Demaille <demaille@gostai.com>
1788 Improve display of directives.
1789 * etc/bench.pl.in (parse_term): Don't add useless eol.
1791 2008-11-11 Akim Demaille <demaille@gostai.com>
1793 Use string_cast in the bench.
1794 * etc/bench.pl.in (generate_grammar_list): Define and use
1797 2008-11-11 Akim Demaille <demaille@gostai.com>
1799 Replace yychar with a Boolean.
1800 * data/lalr1.cc (parse::yychar): Replace by...
1801 (parse::yyempty): this.
1803 2008-11-11 Akim Demaille <demaille@gostai.com>
1808 2008-11-11 Akim Demaille <demaille@gostai.com>
1810 Let yytranslate handle the eof case.
1811 * data/lalr1.cc (yytranslate_): Handle the EOF case.
1813 No longer expect yychar to be equal to yyeof_, rather, test the
1814 lookahead's (translated) kind.
1816 2008-11-11 Akim Demaille <demaille@gostai.com>
1818 yychar cannot be empty in yyerrlab.
1819 * TODO (yychar == yyempty_): New.
1820 * data/lalr1.cc: Remove the handling of this case.
1821 This eases forthcoming changes related to yychar and yytranslate.
1823 2008-11-11 Akim Demaille <demaille@gostai.com>
1825 Bench: syntactic sugar for %define/#define.
1826 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
1827 (&bench_push_parser, bench_variant_parser): Use this feature.
1831 2008-11-11 Akim Demaille <demaille@gostai.com>
1833 Less memory pressure on the "list" bench.
1834 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
1835 the values, to limit memory pressure.
1837 2008-11-11 Akim Demaille <demaille@gostai.com>
1839 Introduce make_symbol.
1840 make_symbol provides a means to construct a full symbol (kind,
1841 value, location) in a single shot. It is meant to be a Symbol
1842 constructor, parameterized by the symbol kind so that overloading
1843 would prevent incorrect kind/value pairs. Unfortunately
1844 parameterized constructors do not work well in C++ (unless the
1845 parameter also appears as an argument, which is not acceptable),
1846 hence the use of a function instead of a constructor.
1848 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1849 (b4_symbol_constructor_declarations)
1850 (b4_symbol_constructor_specialization_)
1851 (b4_symbol_constructor_specializations)
1852 (b4_symbol_constructor_definition_)
1853 (b4_symbol_constructor_definitions): New.
1854 Use them where appropriate to generate declaration, declaration of
1855 the specializations, and implementations of the templated
1856 overloaded function "make_symbol".
1857 (variant::variant): Always define a default ctor.
1858 Also provide a copy ctor.
1859 (symbol_base_type, symbol_type): New ctor overloads for value-less
1861 (symbol_type): Now public, so that functions such as yylex can use
1864 2008-11-11 Akim Demaille <demaille@gostai.com>
1866 Inform m4 whether a tag is a valid id.
1867 * src/output.c (is_identifier): New.
1868 (symbol_definitions_output): Use it to define tag_is_id.
1869 But maybe this should be done at m4 level?
1871 2008-11-11 Akim Demaille <demaille@gostai.com>
1873 Test 214 was failing: it greps with a pattern containing [ ]*
1874 which obviously meant to catch spaces and tabs, but contained only
1875 spaces. Tabulations in sources are a nuisance, so to simplify the
1876 matter, get rid of all the tabulations in the Java sources. The
1877 other skeletons will be treated equally later.
1879 * data/java.m4, data/lalr1.java: Untabify.
1880 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1881 tabulations are no longer generated.
1883 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
1885 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
1886 * configure.ac: Adjust usage.
1887 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1888 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1889 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).
1891 2008-11-10 Di-an Jan <dianj@freeshell.org>
1893 Workaround Java's ``code too large'' problem for parser tables
1894 in most cases, by using one function per initialization.
1895 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
1896 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
1897 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_
1898 yyprhs_, yyrline_, yytranslate_table_): Use b4_integral_parser_table.

1905 * NEWS: Document them.
1907 General Java skeleton improvements.
1908 * configure.ac (gt_JAVACOMP): Request target of 1.4, which allows
1909 using gcj < 4.3 in the testsuite, according to comments in
1910 gnulib/m4/javacomp.m4.
1911 * data/java.m4 (stype, parser_class_name, lex_throws, throws,
1912 location_type, position_type): Remove extraneous brackets from
1913 b4_percent_define_default.
1914 (b4_lex_param, b4_parse_param): Remove extraneous brackets from
1915 m4_define and m4_define_default.
1916 * data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
1917 which marks the end of user code with appropriate syncline, like all
1918 the other skeletons.
1919 (b4_user_post_prologue): Add. Don't silently drop.
1921 (parse): Inline yylex.
1922 * doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
1923 (%{...%}): Fix typo of %code imports.
1924 * tests/java.at (AT_JAVA_COMPILE): Add "java" keyword.
1926 Support annotations on parser class with %define annotations.

1928 * doc/bison.texinfo (Java Parser Interface): Document
1929 %define annotations.

1939 * doc/bison.texinfo (Java Bison Interface): Remove the parts
1940 about %error-verbose having no effect.
1941 (getErrorVerbose, setErrorVerbose): Document.
1943 Move constants for token names to Lexer interface.
1944 * data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.
1945 * data/java.m4 (b4_token_enum): Indent for move to Lexer interface.
1946 (parse): Qualify EOF to Lexer.EOF.
1947 * doc/bison.texinfo (Java Parser Interface): Move documentation of
1948 EOF and token names to Java Lexer Interface.
1949 * tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove Calc qualifier.
1951 Make yyerror public.
1952 * data/lalr1.java (Lexer.yyerror): Use longer parameter name.
1953 (yyerror): Change to public. Add Javadoc comments. Use longer
1954 parameter names. Make the body rather than the declarator
1955 conditional on %locations.
1956 * doc/bison.texinfo (yyerror): Document. Don't mark as protected.
1958 Allow user to add code to the constructor with %code init.

1969 2008-11-10 Akim Demaille <demaille@gostai.com>
1972 * TODO (-D): is implemented.
1973 (associativity): Same precedence must have the same associativity.
1974 For instance, how can a * b / c be parsed if * is %left and / is
1976 (YYERRORCODE, YYFAIL, YYBACKUP): New.
1978 2008-11-10 Akim Demaille <demaille@gostai.com>
1982 2008-11-10 Akim Demaille <demaille@gostai.com>
1984 More information about the symbols.
1985 * src/output.c (type_names_output): Document all the symbols,
1986 including those that don't have a type-name.
1987 (symbol_definitions_output): Define "is_token" and
1989 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
1990 type-name, now that they are defined too in b4_type_names.
1992 2008-11-10 Akim Demaille <demaille@gostai.com>
1996 2008-11-10 Akim Demaille <demaille@gostai.com>
1998 Make parser::yytranslate static.
1999 Small speedup (1%) on the list grammar. And makes yytranslate_
2000 available in non member functions.
2002 * data/lalr1.cc (yytranslate_): Does not need to be a instance
2005 2008-11-10 Akim Demaille <demaille@gostai.com>
2007 Avoid trailing spaces.
2008 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
2009 * data/lalr1.cc: Don't indent before rule and symbol actions, as
2010 they can be empty, and anyway this incorrectly indents the first
2013 2008-11-10 Akim Demaille <demaille@gostai.com>
2017 2008-11-10 Akim Demaille <demaille@gostai.com>
2019 Use "enum" for integral constants.
2020 This is just nicer to read, I observed no speedup.
2022 * data/lalr1.cc (yyeof_, yylast_, yynnts_, yyempty_, yyfinal_)
2023 (yterror_, yyerrcode_, yyntokens_): Define as members of an enum.
2024 (yyuser_token_number_max_, yyundef_token_): Move into...
2025 (yytranslate_): here.
2027 2008-11-10 Akim Demaille <demaille@gostai.com>
2029 Shortcuts in bench directives.
2030 * etc/bench.pl.in (parse_dirs): New.

2033 Create the benches in "benches/".
2035 2008-11-10 Akim Demaille <demaille@gostai.com>

2048 2008-11-10 Akim Demaille <demaille@gostai.com>
2050 Classify symbols by type-name.
2051 * src/uniqstr.h (UNIQSTR_CMP): New.
2052 * src/output.c (symbol_type_name_cmp, symbols_by_type_name)
2053 (type_names_output): New.
2054 (muscles_output): Use it.
2055 * data/lalr1.cc (b4_symbol_action_): Remove.
2056 (b4_symbol_case_, b4_type_action_): New.
2057 Adjust uses of b4_symbol_action_ to use b4_type_action_.
2059 2008-11-10 Akim Demaille <demaille@gostai.com>
2061 Change the handling of the symbols in the skeletons.
2062 Before we were using tables which lines were the symbols and which
2063 columns were things like number, tag, type-name etc. It is was
2064 difficult to extend: each time a column was added, all the numbers had
2065 to be updated (you asked for colon $2, not for "tag"). Also, it was
2066 hard to filter these tables when only a subset of the symbols (say the
2067 tokens, or the nterms, or the tokens that have and external number
2068 *and* a type-name) was of interest.
2070 Now instead of monolithic tables, we define one macro per cell. For
2071 instance "b4_symbol(0, tag)" is a macro name which contents is
2072 self-decriptive. The macro "b4_symbol" provides easier access to
2075 * src/output.c (type_names_output): Remove.
2076 (symbol_numbers_output, symbol_definitions_output): New.
2077 (muscles_output): Call them.
2078 (prepare_symbols): Define b4_symbols_number.
2080 2008-11-10 Akim Demaille <demaille@gostai.com>
2083 * src/getargs.h, src/getargs.c (trace_muscle): New.
2084 (trace_types, trace_args): Support it.
2085 * src/output.c (output_skeleton): Use it.
2087 2008-11-10 Akim Demaille <demaille@gostai.com>
2090 * src/output.c (muscles_output): New, extracted from...
2091 (output_skeleton): here.

2098 2008-11-10 Akim Demaille <demaille@gostai.com>
2100 Update the variant example.
2101 * examples/variant.yy: Formatting changes.
2104 2008-11-10 Akim Demaille <demaille@gostai.com>
2106 Support constructor with an argument.
2107 This improves the "list" bench by 2%.
2109 * data/lalr1.cc (variant::build): Add an overloaded version with
2111 * tests/c++.at (AT_CHECK_VARIANT): Check it.
2113 2008-11-10 Akim Demaille <demaille@gostai.com>
2116 * tests/c++.at (AT_CHECK_VARIANTS): New.
2117 Use it with and without %define assert.
2119 2008-11-10 Akim Demaille <demaille@gostai.com>
2121 Add %precedence support.
2122 Unfortunately it is not possible to reuse the %prec directive. This
2123 is because to please POSIX, we do not require to end the rules with a
2124 semicolon. As a result,
2128 is ambiguous: either a rule which precedence is that of baz, or a rule,
2129 and then a declaration of the precedence of the token baz.
2131 * doc/bison.texinfo: Document %precedence.
2132 (Precedence Only): New.
2133 * src/assoc.h, src/assoc.c (precedence_assoc): New.
2134 * src/conflicts.c (resolve_sr_conflict): Support it.
2135 * src/scan-gram.l, src/parse-gram.y (%precedence): New token.
2137 * tests/calc.at: Use %precedence for NEG.
2138 * tests/conflicts.at (%precedence does not suffice)
2139 (%precedence suffices): New tests.
2141 2008-11-09 Akim Demaille <demaille@gostai.com>
2143 Make benches in a sub dirs.

2176 (@token, $grammar, $bench): New.
2177 (generate_grammar_variant): Rename as...
2178 (generate_grammar_list): this.

2391 Add "%define assert" to variants.
2392 This is used to help the user catch cases where some value gets
2393 ovewritten by a new one. This should not happen, as this will
2396 Unfortunately this uncovered a bug in the C++ parser itself: the
2397 lookahead value was not destroyed between two calls to yylex. For
2398 instance if the previous lookahead was a std::string, and then an int,
2399 then the value of the std::string was correctly taken (i.e., the
2400 lookahead was now an empty string), but std::string structure itself
2403 This is now done in variant::build(other&) (which is used to take the
2404 value of the lookahead): other is not only stolen from its value, it
2405 is also destroyed. This incurs a new performance penalty of a few
2406 percent, and union becomes faster again.

2685 2008-11-03 Akim Demaille <demaille@gostai.com>
2687 Fuse the three stacks into a single one.
2689 In order to make it easy to perform benchmarks to ensure that
2690 there are no performance loss, lalr1.cc is forked into
2691 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2694 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2695 exercized by the test suite, the user must install a symbolic link
2696 from lalr1.cc to it.
2698 Instead of having three stacks (state, value, location), use a
2699 stack of triples. This considerably simplifies the code (and it
2700 will be easier not to require locations as currently does the C++
2701 parser), and also gives a 10% speedup according to
2702 etc/bench (probably mainly since memory allocation is done once
2703 instead of three times).
2705 Another motivation is to make it easier to destruct properly
2706 semantic values: now that they are bound to their state (hence
2707 symbol type) it will be easier to call the appropriate destructor.
2709 These changes should probably benefit the C parser too.
2711 * data/lalr1.cc: Copy as...
2712 * data/lalr1-fusion.cc: this new file.
2713 (b4_rhs_value, b4_rhs_location): New definitions overriding those

2724 This is needed to prepare a forthcoming patch that fuses the three
2727 * data/lalr1.cc (parser::yypush_): New.
2728 (parser::yynewstate): Change the semantics: instead of arriving to
2729 this label when value and location have been pushed, but yystate
2730 is to be pushed on the state stack, now the three of them must
2731 have been pushed before. yystate still must be the new state.
2732 This allows to use yypush_ everywhere instead of individual
2733 handling of the stacks.

2752 2008-11-03 Akim Demaille <demaille@gostai.com>
2754 Use variants to support objects as semantic values.
2755 This patch was inspired by work by Michiel De Wilde. But he used
2756 Boost variants which (i) requires Boost on the user side, (ii) is
2757 slow, and (iii) has useless overhead (the parser knows the type of
2758 the semantic value there is no reason to duplicate this
2759 information as Boost.Variants do).
2761 This implementation reserves a buffer large enough to store the
2762 largest objects. yy::variant implements this buffer. It was
2763 implemented with Quentin Hocquet.
2765 * src/output.c (type_names_output): New.
2766 (output_skeleton): Invoke it.
2767 * data/c++.m4 (b4_variant_if): New.

2770 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
2771 (b4_char_sizeof, yy::variant): New.
2772 (parser::parse): If variants are requested, define
2773 parser::union_type, parser::variant, change the definition of
2774 semantic_type, construct $$ before running the user action instead
2775 of performing a default $$ = $1.
2776 * examples/variant.yy: New.
2777 Based on an example by Michiel De Wilde.
2779 2008-11-03 Akim Demaille <demaille@gostai.com>
2781 Parameterize the extraction of semantic values.

2815 2008-11-02 Joel E. Denny <jdenny@ces.clemson.edu>
2817 Say %language is experimental.
2818 We're thinking of extending it's effect on output file naming. See the

2896 Always put auxiliary code files in the same dir as other output files.
2897 * src/files.c (compute_file_name_parts): When the user specifies
2898 --output but not --file-prefix, extract the directory prefix from the

3164 .prev-version, and .version.
3165 * NEWS (2.3b+): Rename to...
3166 (?.?): ... this because we're dropping the "+" version naming scheme,
3167 but, in general, we still can't be sure of our next release name.
3168 * bootstrap: Add a quick hack to remove from .gitignore the
3169 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile

3267 2008-05-23 Joel E. Denny <jdenny@ces.clemson.edu>
3269 * HACKING: Don't say don't mention HACKING in the ChangeLog. We've
3270 been doing it for years.
3271 (Test suite): Mention maintainer-push-check and maintainer-xml-check.
3272 (Release Procedure): Add FIXME about make alpha being unmaintained.

3294 2008-04-23 Eric Blake <ebb9@byu.net>
3296 Revert prior patch, by working around autoconf regression.
3297 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
3298 ("Output file name: ("): Uncomment test.
3299 ("Output file name: )"): Likewise.
3300 Based on an idea from Noah Misch.
3302 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
3304 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
3305 2.61. Reported by Juan Manuel Guerrero at
3306 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
3307 * tests/output.at ("Output file name: ("): Comment out test case for
3309 ("Output file name: )"): Likewise.
3311 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
3313 * GNUmakefile: Update git-version-gen invocation so make dist
3316 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
3318 Update to the current gnulib CVS repository, and fix trigraph handling
3320 * bootstrap: Update gnulib CVS repository URL.
3321 (symlink_to_dir): Encapsulate the code that guarantees the destination
3322 directory exists into...
3323 (check_dst_dir): ... this new function, and...
3324 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
3325 fail when copying files into lib/uniwidth/.
3326 * src/output.c (prepare_symbols): When writing yytname muscles, where
3327 symbol names will be encoded in C-string literals, tell quotearg to
3328 escape trigraphs. This used to be the default in gnulib.
3329 * tests/regression.at (Token definitions): Because of the change in
3330 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
3331 escapes trigraphs in symbol names. Thus, yytname no longer has
3332 trigraphs unnecessarily doubly escaped. Update test case output.
3333 Extend test case to be sure Bison's own error messages will no longer
3334 have trigraphs in symbol names unnecessarily escaped once.

3349 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
3350 consistency. Update the -g and -x entries now that they take
3351 arguments. Use brackets to indicate optional arguments.
3352 * src/getargs.c (usage): Explain the relationship between arguments of
3353 long and short options more completely. Document --defines and -d
3354 separately since the former takes an argument but, for POSIX Yacc, the
3356 (short_options): Let -W take an optional argument like --warnings.

3374 Fix the handling of $opt which resulted in all the argument to be
3375 considered as optional.

4158 Pacify ./configure --enable-gcc-warnings.
4159 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument

4161 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
4162 local variable `sep'.
4164 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
4166 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
4168 * src/print-xml.c: Prefer "const" after types; that's more consistent.
4169 (xml_printf): Indent just 1 space for level.
4170 (e_char, xlate_char): Remove.
4171 (xml_escape_string): Rewrite to avoid undefined behavior (used
4172 storage that was freed from the stack).
4173 (xml_escape_n): Don't bother checking for subscript error.
4175 2007-09-21 Wojciech Polak <polak@gnu.org>

4224 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
4225 Bruno Haible <bruno@clisp.org>
4227 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
4228 and is a script that invokes bison. Tighten the code. Add comments.
4230 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

4242 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
4244 In impure push mode, don't allow more than one yypstate to be allocated
4245 since multiple impure parsers would corrupt yynerrs.
4246 * data/push.c (yypstate_allocated): New static global variable
4248 (yypull_parse): If yypstate_new returns 0, don't report it as memory
4249 exhaustion if yypstate_allocated is 1, but still return 2.
4250 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
4251 already 1. Otherwise, set it to 1.
4252 (yypstate_delete): Set it to 0.
4253 * tests/push.at (Push Parsing: Multiple impure instances): New test
4256 2007-08-17 Bob Rossi <bob@brasko.net>

4327 Get rid of broken %no-parser, -n, and --no-parser implementation and
4329 * TODO: Don't mention them.
4330 * doc/bison.1: Likewise.
4331 * doc/bison.texinfo (Decl Summary): Likewise.
4332 (Bison Options): Likewise.
4333 (Option Cross Key): Likewise.
4334 * src/getargs.c (no_parser_flag): Remove global variable.
4335 (usage): Don't print description of -n and --no-parser.
4336 (long_options): Remove --no-parser entry here.
4337 (getargs): Remove -n case in the switch here.
4338 * src/getargs.h (no_parser_flag): Remove extern.
4339 * tests/regression.at (Web2c Actions): Remove comment that mentions
4342 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
4344 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
4345 name user variables starting with `yy'. Just pass NULL instead of a
4346 dummy local &yylval to yypush_parse.
4347 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
4350 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
4352 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
4353 true since it's then always used regardless of whether yyoverflow is
4354 defined. Reported by Christian Burger at
4355 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
4356 * THANKS: Add Christian Burger.
4358 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4359 node names: say "Decl Summary" not "Bison Declaration Summary".
4361 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
4363 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
4364 determine whether this function has already complained about an invalid
4365 value for a %define boolean variable, don't check whether Bison has
4366 ever examined the value. As written, the check was a tautology.
4367 Instead, record and check for this complaint using a separate muscle.
4369 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
4371 Fix push parsing memory leak reported by Brandon Lucia at
4372 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
4373 * THANKS: Add Brandon Lucia.
4374 * data/push.c (yypstate_delete): Free the stack if it was reallocated
4375 but the parse never completed and thus freed it.
4376 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
4377 * tests/testsuite.at: Include push.at.
4378 * test/push.at: New.
4379 (Push Parsing: Memory Leak for Early Deletion): New test case.
4381 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
4383 Improve handling of multiple S/R conflicts in the same state and of S/R
4384 conflicts involving multiple reductions.
4385 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
4386 set for a state here or Bison will abort if it is reassigned on a
4387 later conflicted reduction in the same state.
4388 Similarly, don't finalize and assign the solved conflicts report here
4389 or it will be lost if it is reassigned on a later conflicted reduction
4391 (set_conflicts): Instead, assign them both here after all S/R conflicts
4392 in the state have been fully examined.
4393 * src/print.c (shift_set): Rename to...
4394 (no_reduce_set): ... this.
4395 (print_reductions): Update for rename, and add %nonassoc error action
4396 tokens to no_reduce_set so that, when printing the first remaining
4397 reduction on an error action token, the reduction is enclosed in
4399 (print_results): Update for rename.
4400 * tests/conflicts.at (Solved conflicts report for multiple reductions
4401 in a state): New test case.
4402 (%nonassoc error actions for multiple reductions in a state): New test
4405 * src/main.c (main): Don't depend on C99 features.
4407 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
4409 * build-aux/.cvsignore: Add compile.
4410 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
4413 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
4415 * bootstrap (slurp): Create target directories that don't exist.
4416 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
4418 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4420 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
4422 * closure.c (closure): Likewise.
4423 * state.h (reductions): Comment sorting of rules.
4424 (state): Comment sorting of items.
4426 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
4428 Fix C++ test cases after recent Gnulib changes. Discussed starting at
4429 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
4430 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
4431 definition in order to avoid Gnulib headers since we don't use config.h
4433 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
4434 rather than AT_DATA so that config.h is included.
4436 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
4438 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
4439 instead of fprintf. Guard these functions with #if YYDEBUG instead of
4440 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
4441 and so that YYFPRINTF is guaranteed to be defined here.
4443 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4445 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
4447 (muscle_percent_define_check_values): ... this more helpful function.
4448 Again, it's not used yet, but it will be.
4449 * src/muscle_tab.h: Likewise.
4451 Improve some comments in parser table construction.
4452 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
4453 (generate_states): Don't mention ruleset, which is internal to closure.
4454 * src/closure.c (closure): Explain sorting of core and itemset, which
4455 is required for this function to behave correctly.
4456 * src/closure.h (closure): Mention sorting.
4458 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
4460 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4461 move the check for disabled transitions to an aver since conflict
4462 resolution hasn't happened yet.
4464 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4465 labels a state as inconsistent just because it has error transitions.
4466 The original form of this check appeared in revision 1.1 of lalr.c,
4467 which was committed on 1991-12-21. Now (at least), changing the
4468 consistency label on such a state appears to have no useful effect in
4469 any of the places it is examined, which I enumerate below. The key
4470 point to understanding each item in this enumeration is that a state
4471 with an error transition is labelled consistent in the first place only
4472 if it has no rules, so the check cannot matter for states that have
4473 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4474 to try to identify its conflicts, and a state must have *rules* to have
4475 conflicts. (2) Labelling a state as inconsistent will affect how
4476 action_row sets the default *rule* for the state. (3) Labelling a
4477 state as inconsistent will cause build_relations to add lookback edges
4478 to *rules* in that state.
4479 * src/state.h (struct state): Word the comment for member consistent
4482 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
4484 Don't depend on C99 features.
4485 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
4486 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
4487 * src/reader.c (check_and_convert_grammar): Fix for-loop.
4488 * src/state.c (state_mark_reachable_states): Fix for-loop.
4489 (state_remove_unreachable_states): Fix for-loop.
4491 Don't widen struct state with member reachable just to temporarily
4492 record reachability. Instead, use a local bitset.
4493 * src/state.h (struct state): Remove member.
4494 * src/state.c (state_new): Don't initialize it.
4495 (state_mark_reachable_states): Rename to...
4496 (state_record_reachable_states): ... this, and use bitset.
4497 (state_remove_unreachable_states): Use bitset.
4499 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
4501 * src/Makefile.am (yacc): Quote target action commands properly so
4502 that the yacc script isn't corrupt. Reported by Hans Aberg at
4503 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
4505 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
4506 the case of pure parsers. Reported by Frans Englich at
4507 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
4508 * THANKS: Add Frans Englich.
4510 * NEWS (2.3a+): In the %code entry, reference section `Bison
4511 Declaration Summary' from the manual now since the %code summary has
4513 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
4514 in the rules section must be terminated by semicolons.
4516 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
4518 Extend the front-end API for %define variables to more completely
4519 mirror the back-end. This will be useful in the future.
4520 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
4521 Update comments to mention the new front-end counterparts of these
4523 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code
4524 for muscle_string_decode and muscle_location_decode.
4525 (muscle_string_decode): New static function.
4526 (muscle_location_decode): Use MUSCLE_COMMON_DECODE.
4527 (muscle_percent_define_get, muscle_percent_define_ifdef): New
4529 (muscle_percent_define_flag_if): Use muscle_percent_define_ifdef and
4530 muscle_percent_define_get to mimic the b4_percent_define_flag_if
4531 implementation more closely.
4532 (muscle_percent_define_invalid_value): New function.
4533 * src/muscle_tab.h (muscle_percent_define_get,
4534 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
4537 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
4539 * NEWS (2.3a+): Mention yesterday's state-removal change.
4540 (2.3a): Remove the %language entry, which was added after 2.3a.
4541 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
4542 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
4543 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
4544 tests/existing.at: Update copyright date.
4546 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
4548 If conflict resolution makes states unreachable, remove those states,
4549 report rules that are then unused, and don't report conflicts in those
4551 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
4552 New global function.
4553 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global

4566 an unused rule is discovered.
4568 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
4570 Minor code cleanup in parser table construction.
4571 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
4572 (new_itemsets, save_reductions): Update for rename to nitemset.
4573 * src/closure.c (nritemset): Rename to...
4574 (nitemset): ... this since the "r" appears to meaningless and isn't
4575 used in the comments.
4576 (closure): Update for rename.
4577 * src/closure.h (nritemset): Update extern to...
4578 (nitemset): ... this.

4586 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
4587 still sticks to ASCII. Sorry!

4640 DJGPP spefic issue. Inhibit the use of disallowed characters for
4641 file name genertion on Win98, WinXP, etc. These are |<>":?*\
4642 and concern testsuite case 46.

4661 %define and %code directives.
4663 Make it easy to share %define boolean variables between the front-end
4664 and back-end. Though not used yet, this will be useful in the future.
4665 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
4666 Bison uses of names rather than just skeleton uses of names.
4667 (b4_percent_define_get, b4_percent_define_ifdef): Rename

4674 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
4675 muscle_percent_define_default): New functions mimicking
4676 b4_percent_define_flag_if and b4_percent_define_default.
4678 For %define variables, report locations for invalid values and
4680 * data/bison.m4 (b4_percent_define_flag_if): Read
4681 b4_percent_define_loc(VARIABLE) to report the location of an invalid
4683 (b4_percent_define_default): Save a special location in
4684 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE

4709 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
4711 * data/lalr1.java: Prefix all private members with yy.
4713 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
4715 Use YYFPRINTF instead of fprintf where appropriate. Reported by
4716 Sebastien Fricker at
4717 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
4718 * THANKS: Add Sebastien Fricker.
4719 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
4720 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must

4733 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
4735 Undo my 2007-02-07 change, switching back to the c-strcase module
4736 introduced in the 2007-02-03 change. Bruno Haible reported that
4737 the 2007-02-07 change would be dangerous in Turkish if we add a
4738 language whose name contains "i", since "i" is not lowercase "I"
4740 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
4741 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
4742 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
4743 * m4/.cvsignore: Remove strcase.m4.
4744 * src/getargs.c: Revert 2007-02-07 change, as follows.
4745 Include c-strcase.h.
4746 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
4748 2007-02-11 Bruno Haible <bruno@clisp.org>
4750 Enable the Java related testsuite tests when the only Java compiler
4751 found is a gcj < 4.3. Discussed at
4752 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
4753 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
4755 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
4757 * data/Makefile.am: Update copyright date.
4758 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
4759 yypstate_new returns NULL.
4760 (yypstate_new): Return NULL if malloc does.
4761 * src/reader.c (packgram): Move translation of rule actions from the
4762 beginning of packgram to...
4763 (check_and_convert_grammar): ... here right before packgram is invoked
4764 so it's easier to write more complete comments, and remove redundant
4767 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
4769 As in semantic actions, make @$ in %initial-action, %destructor, and
4770 %printer imply %locations.
4771 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
4773 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
4774 (@$ in %initial-action implies %locations,
4775 @$ in %destructor implies %locations,
4776 @$ in %printer implies %locations): ... these new test cases.
4778 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
4780 Undo most of the 2007-02-03 change, switching to the strcase module
4781 now that gnulib strcase has been fixed.
4782 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
4783 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
4784 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
4785 * m4/.cvsignore: Add strcase.m4.
4786 * src/getargs.c: Revert 2007-02-03 change, as follows.
4787 Don't include c-strcase.h.
4788 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4789 strcasecmp has "unspecified behavior" outside the POSIX locale,
4790 but it works fine in practice if at least one argument is ASCII,
4791 as is the case in Bison.
4793 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
4795 * tests/java.at: Skip tests if only one of javac/java is present.
4796 Reported by Joel E. Denny.
4797 * tests/atlocal.in: Adjust copyright years.
4799 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
4801 * data/lalr1.java (Stack): Work around old verifiers that disallow
4802 access to the private fields of an inner class, from the outer class.
4803 We can make Stack's fields public because user code doesn't have access
4804 to the instance of Stack used by parse(). Reported by Paul Eggert.
4806 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4808 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4809 the right spot for these files?
4810 * bootstrap.conf (gnulib_modules): Add c-strcase.
4811 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4813 * src/getargs.c: Include c-strcase.h.
4814 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4815 to avoid unspecified behavior.
4817 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
4819 * doc/bison.texinfo (Decl Summary): Correct typo.
4821 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
4823 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
4824 Complain if the value does not match empty, "true" or "false".
4825 * data/c++.m4: Adjust default definitions of %define variables.
4826 * data/java.m4: Adjust default definitions of %define variables.
4827 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
4829 * tests/input.at (Boolean %define variables): Test new behavior.
4831 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
4833 * NEWS: Mention java.
4834 * TODO: Remove things that are done.
4835 * bootstrap.conf: Add javacomp-script and javaexec-script.
4836 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
4838 * data/Makefile.am: Add new files.
4839 * data/java-skel.m4: New.
4840 * data/java.m4: New.
4841 * data/lalr1.java: New.
4843 * doc/bison.texinfo: Put "A Complete C++ Example" under
4844 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
4845 under Other Languages.
4847 * src/getargs.c (valid_languages): Add Java.
4848 * src/getargs.h (struct bison_language): Update size of string fields.
4850 * tests/Makefile.am: Add java.at.
4851 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
4852 * tests/java.at: New.
4853 * tests/testsuite.at: Include it.
4855 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
4858 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4859 at_directive_argv arguments so these no longer have to be global
4860 variables. Also, update the implementation for the following changes.
4861 (fail_for_at_directive_too_many_args,
4862 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4863 (at_directive_name): Remove as at_directive_argv[0] will be used for
4865 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4866 for the directive name.
4867 (at_directive_argc, at_directive_argv): Make these local within
4868 skel_lex instead of global.
4869 (INITIAL): Update directive start action for above changes.
4870 (SC_AT_DIRECTIVE_ARG): Rename to...
4871 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4872 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4873 (scan_skel): Move yylex_destroy to...
4874 (skel_scanner_free): ... here.
4875 * tests/skeletons.at (installed skeleton file name): Rename to...
4876 (installed skeleton file names): ... this.
4878 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4880 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4881 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4882 Summary" not "Directives".
4883 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4884 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4885 since the former is now the more complete one.
4886 (Prologue Alternatives): Likewise and do the same for %defines.
4887 (Table of Symbols): Add summary of %code, add summary of %define, and
4888 move full %code documentation to...
4889 (Decl Summary): ... here for consistency with other entries in these
4891 Move %define entry in order to keep this list alphabetized.
4892 Reword %define entry a little to put less emphasis on the skeleton
4893 concept, which most users shouldn't have to think about.
4895 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
4897 Adjust to recent gnulib changes.
4898 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
4899 Add string.h, string_.h, unistd_.h, wchar_.h.
4900 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
4901 * src/system.h: Don't include <stpcpy.h>; this is now done by
4904 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
4906 Simplify implementation of unqualified %code, implement macros for
4907 uniform treatment of boolean %define flags. Document %define.
4908 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
4909 b4_percent_code_ifdef): New.
4910 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
4911 * data/c++.m4: Define default value for global_tokens_and_yystype.
4912 * data/glr.cc: Likewise.
4913 * data/location.cc: Use b4_percent_define_flag_if.
4915 * doc/bison.texinfo (Decl Summary): Document %define.
4917 * src/parse-gram.y (Unqualified %code): Change muscle name to
4919 (content.opt): Default to empty.
4921 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4923 Implement support for relative and absolute skeleton file names.
4924 Discussed starting at
4925 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
4926 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
4927 (Bison Options): Document in --skeleton entry.
4928 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
4929 full_skeleton can't necessarily hold all of pkgdatadir.
4930 If the specified skeleton file name contains a `/', don't prepend
4932 * src/parse-gram.y (prologue_declaration): If the specified skeleton
4933 file name contains a `/', prepend the grammar file directory.
4934 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
4935 * skeletons.at: New file.
4936 (relative skeleton file names): New test case.
4937 (installed skeleton file names): New test case.
4938 * tests/testsuite.at: Include skeletons.at.
4940 * bootstrap: Update copyright to 2007.
4942 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
4944 * bootstrap: Remove occurrences of .#bootmp from the files.
4946 2007-01-17 Akim Demaille <akim@epita.fr>
4948 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
4950 Use per-type %printer.
4952 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4954 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

4962 2007-01-16 Akim Demaille <akim@epita.fr>
4964 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
4966 (Calc++ Scanner): Exit with failure if we can't open the input
4968 Accept "-" standing for stdin.
4969 (Calc++ Top Level): Print the result only if the parsing was
4972 2007-01-16 Akim Demaille <akim@epita.fr>
4974 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
4976 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
4977 and Joel E. Denny <jdenny@ces.clemson.edu>
4979 Clean up %define and %code implementation in M4 some. Most
4980 importantly, rename all related macros to be in the b4_percent_define
4981 and b4_percent_code namespaces. Also, complete support for `.' in
4982 %define variable names and %code qualifiers.
4983 * data/bison.m4 (b4_check_user_names): Check for special
4984 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4986 (b4_get_percent_define, b4_get_percent_code): Rename to...
4987 (b4_percent_define_get, b4_percent_code_get): ... these.
4988 Extend documentation with examples.
4989 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4990 b4_percent_define_skeleton_variables and
4991 b4_percent_code_skeleton_qualifiers.
4992 Expect any value for the %define variable `foo' to be stored in the
4993 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4994 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4995 expect any unqualified %code blocks to be stored in a macro named
4996 `b4_percent_code_unqualified'.
4997 Use m4_indir so that %define variable names and %code qualifiers can
4998 contain `.', which is allowed by the grammar parser.
4999 (b4_percent_define_default): New macro to set a default value for a
5001 (m4_wrap): Update wrapped code, and fix some underquoting.
5002 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
5003 Expect grammar uses of %define variables and %code qualifiers to be
5004 defined in b4_percent_define_user_variables and
5005 b4_percent_code_user_qualifiers.
5006 * data/c++.m4: Use b4_percent_define_default rather than
5007 m4_define_default. Fix some underquoting. Skeleton usage of %define
5008 variable define_location_comparison now implies skeleton usage of
5009 %define variable filename_type.
5010 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5011 data/push.c, data/yacc.c: Update macro names.
5012 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
5015 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5017 DJGPP specific issues.
5019 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
5020 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
5022 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5024 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
5025 run parsers in all tests so that Valgrind is invoked during
5026 maintainer-check-valgrind.
5027 (Duplicate representation of merged trees): Free all semantic values.
5028 (Duplicated user destructor for lookahead): Likewise.
5030 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5032 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
5033 command-line prefix.
5034 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
5035 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
5036 miss Valgrind messages.
5037 (Exploding the Stack Size with Malloc): Likewise.
5039 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5041 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
5042 locals. Reported by Juan Manuel Guerrero at
5043 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
5044 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
5045 Fix some indentation also.
5046 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
5047 explaining this issue.
5049 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
5050 and Joel E. Denny <jdenny@ces.clemson.edu>
5052 Simplify union and prologue handling, and escape union and lex/parse
5053 params with digraphs.
5054 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
5055 values to the empty string since these are no longer guaranteed
5056 initialized by the front-end.
5057 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
5058 braces around b4_user_stype since this is no longer done by the
5060 * src/files.c, src/files.h (pre_prologue_obstack,
5061 post_prologue_obstack): Remove.
5062 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
5063 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
5064 with digraphs. This fixes lex params and parse params.
5065 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
5066 * src/output.c (prepare): Remove muscle insertion of the prologues.
5067 (output): Remove freeing of pre_prologue_obstack and
5068 post_prologue_obstack.
5069 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
5070 than prologue_augment for prologue parsing so you don't need prologue
5072 (grammar_declaration): For %union RHS, use `braceless' instead of
5073 "{...}" so that braces are already stripped and code is escaped with
5075 * src/reader.c (prologue_augment): Remove.
5076 (reader): Remove initialization of pre_prologue_obstack and
5077 post_prologue_obstack.
5078 * src/reader.h (prologue_augment): Remove.
5080 * data/c.m4: Remove stray parenthesis.
5082 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5084 Remove quotes from variables names in %define directives and from
5085 qualifiers in %code directives, and restrict the characters that are
5086 allowed in them to M4-friendly ones. For %define, continue to support
5087 the quoted form as a deprecated feature. Discussed starting at
5088 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
5089 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
5091 * doc/bison.texinfo (Prologue Alternatives): Update.
5092 (Decl Summary): In %defines entry, update mention of `%code requires'
5093 and `%code provides'.
5094 (C++ Location Values): Update %define uses.
5095 (Calc++ Parser Interface): Likewise.
5096 (Calc++ Parser): Likewise, and update `%code requires' uses.
5097 (Table of Symbols): Update %code documentation.
5098 * src/parse-gram.y (prologue_declaration): For %define variables, use
5099 `variable' instead of `STRING'.
5100 (grammar_declaration): For %code qualifiers, use `ID' instead of
5102 (variable): New nonterminal that takes an `ID' or a `STRING'.
5103 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
5105 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
5106 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
5107 (%define errors): Update %define uses.
5109 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5111 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
5112 instead of muscle_insert for %define values so that M4-special
5113 characters are replaced with digraphs.
5114 * tests/input.at (%define errors): Extend to check weird values.
5116 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5118 Instead of having skeletons declare all valid %define variables and
5119 %code qualifiers, provide macros that retrieve the associated values
5120 and build these lists automatically. Thus Bison will now warn when a
5121 variable or qualifier is not used by the skeleton in the current
5122 invocation regardless of whether it might sometimes be used by that
5123 skeleton in other invocations. Also, move all %define value macros to
5124 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
5125 form, which is replaced by %code.
5126 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
5127 (b4_check_user_names): ... this, and change the series of valid name
5128 arguments to a single list argument for names used in the skeleton
5129 similar to the existing list argument for names used in the grammar.
5130 Warn instead of complaining.
5131 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
5132 values and %code code, to format %code code properly, and to build
5133 lists of all %define variables and %code qualifiers used in the
5134 skeleton: b4_skeleton_percent_define_variables and
5135 b4_skeleton_percent_code_qualifiers.
5136 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
5138 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
5139 the skeleton names lists can finish building first. In place of
5140 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
5141 expect the lists b4_user_percent_define_variables and
5142 b4_user_percent_code_qualifiers.
5143 * data/c++.m4: Where setting default values for b4_parser_class_name,
5144 b4_location_type, b4_filename_type, b4_namespace, and
5145 b4_define_location_comparison, update their names to the
5146 b4_percent_define_ namespace.
5147 * data/glr.c: Don't use b4_check_percent_define_variables and
5148 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
5149 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
5150 (b4_parser_class_name, b4_namespace): Define these using
5151 b4_get_percent_define for parser_class_name and namespace.
5152 * data/location.cc: Use b4_get_percent_define.
5153 * data/push.c: Don't use b4_check_percent_define_variables and
5154 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
5155 * data/yacc.c: Likewise, and don't call m4_exit in
5156 b4_use_push_for_pull_if or m4_wrap code will never execute.
5157 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
5159 (muscle_grow_user_name_list): ... this for consistency with the
5160 terminology used in bison.m4.
5161 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
5162 %define variable names, and rename muscle used_percent_define_variables
5163 to user_percent_define_variables.
5164 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
5165 user_percent_code_qualifiers.
5167 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
5168 {CODE} form is no longer accepted.
5169 * tests/input.at (Reject bad %code qualifiers): Rename to...
5170 (Reject unused %code qualifiers): ... this, and update test output.
5171 (%define error): Update test output.
5173 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
5175 Check for unrecognized %define variables similar to checking for
5176 unrecognized %code qualifiers. Check for redefined %define variables.
5177 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
5179 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
5180 (b4_check_percent_define_variables): New, also wraps it.
5181 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
5182 variables using b4_check_percent_define_variables.
5183 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
5184 all those exercised in the test suite and all those listed in the
5185 `Default values' section of c++.m4. Are there others?
5186 * data/push.c, data/yacc.c: Declare no valid %define variables.
5187 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
5188 similar to muscle_find, but it works even when the muscle stores a
5190 (muscle_grow_used_name_list): New function for constructing the used
5191 name list muscles that b4_check_for_unrecognized_names requires.
5192 * src/parse-gram.y (prologue_declaration): Warn if a variable is
5193 %define'd more than once. Define the b4_used_percent_define_variables
5194 muscle with muscle_grow_used_name_list.
5195 (grammar_declaration): Abbreviate %code code with
5196 muscle_grow_used_name_list.
5197 * tests/input.at (%define errors): New.
5199 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5201 Provide warn_at, complain_at, and fatal_at function callbacks to the
5202 skeletons, and use this for %code qualifier complaints.
5203 * data/bison.m4 (b4_error_at): New, invoked by...
5204 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
5205 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
5206 @fatal_at(...@) directives.
5207 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
5208 qualifiers in b4_used_percent_code_qualifiers and to use
5210 * src/location.c, src/location.h (boundary_set_from_string): New global
5212 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
5214 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
5215 to b4_used_percent_code_qualifiers.
5216 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
5218 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
5219 (lineno): Rename to...
5220 (out_lineno): ... this so I don't misunderstand it again.
5221 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
5222 here; these newlines are in the input but not the output file.
5223 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
5224 (at_directive_perform): ... this new static function, and add handling
5225 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
5227 * tests/input.at (Reject bad %code qualifiers): Update test output with
5228 locations and extend.
5230 * tests/output.at (Output file name: [, Output file name: ]): Remove
5231 bogus comment about these tests failing.
5233 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5235 Clean up b4_check_percent_code_qualifiers a little.
5236 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
5237 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
5238 documentation and add examples.
5239 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
5242 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5244 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
5245 unreliable -- especially when they're hidden inside another macro.
5246 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
5247 data/c.m4: Remove m4_divert(-1).
5248 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5249 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
5250 m4_divert_push(0) and m4_divert_pop(0).
5251 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
5252 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
5253 pushed and popped by m4sugar, should be first on the stack.
5255 Provide warn, complain, and fatal function callbacks to the skeletons.
5256 This provides more flexibility than m4_fatal, improves the error
5257 message format, and captures messages for translation. Discussed
5259 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
5260 * data/bison.m4 (b4_error): New, invoked by...
5261 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
5262 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
5263 directives. Because these M4 macros might be called when the current
5264 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
5265 the previous removal of uses of m4_divert, which caused trouble.
5266 (b4_check_percent_code_qualifiers): Use b4_complain instead of
5267 m4_fatal to report unrecognized %code qualifiers.
5268 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
5269 push parser requests.
5270 * data/glr.c: Use b4_complain instead of m4_fatal to report
5271 non-deterministic push parser requests.
5272 Update @output usage to @output(...@) form.
5273 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
5274 report missing %defines. Update @output usage to @output(...@) form.
5275 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
5277 * src/main.c (main): Invoke skel_scanner_free.
5278 * src/scan-skel.h (skel_scanner_free): Prototype new function.
5279 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
5280 obstack_for_string from flex-scanner.h.
5281 (YY_DECL): Use to declare skel_lex static.
5282 (decode_at_digraphs): Remove; now handled in the new
5283 SC_AT_DIRECTIVE_ARG start condition.
5284 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
5286 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
5287 at_directive_argv): New static globals.
5288 (INITIAL): Use fail_for_invalid_at.
5289 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
5290 recognize the start of a generalized `@directive(...@)' form and
5292 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
5293 directive args (using the new obstack_for_string), to decode the
5294 contained @ diagraphs, and to perform the directive. It recognizes
5295 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
5297 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
5298 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
5300 (scan_skel): Initialize obstack_for_string on the first call.
5301 (skel_scanner_free): New function to free obstack_for_string.
5302 * tests/input.at (Reject bad %code qualifiers): Update test output.
5304 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
5306 Consolidate the 4 prologue alternative directives (%code, %requires,
5307 %provides, and %code-top) into a single %code directive with an
5308 optional qualifier field. Discussed at
5309 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
5310 * NEWS (2.3a+): Rewrite the existing entry for the prologue
5312 * doc/bison.texinfo (Prologue Alternatives): Update.
5313 (Decl Summary): Update to %code "requires" and %code "provides".
5314 (Calc++ Parser): Update to %code "requires".
5315 (Table of Symbols): Remove entries for %requires, %provides, and
5316 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
5317 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
5318 are replaced by b4_percent_code_provides and b4_percent_code_requires,
5319 which are skeleton-specific.
5320 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
5321 declare what %code qualifiers it supports and to complain if any other
5322 qualifiers were used in the grammar.
5323 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
5324 and b4_user_code([b4_percent_code_provides]) in place of
5325 b4_user_requires and b4_user_provides.
5326 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
5327 Add b4_user_code([b4_percent_code_top]) and
5328 b4_user_code([b4_percent_code]).
5329 Invoke b4_check_percent_code_qualifiers.
5330 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
5331 PERCENT_REQUIRES): Remove.
5332 (grammar_declaration): Remove RHS's for %code-top, %provides, and
5333 %requires. Rewrite the %code RHS as the unqualified form defining the
5334 muscle b4_percent_code. Add another RHS for the qualified %code form,
5335 which defines muscles of the form b4_percent_code_QUALIFIER and the
5336 b4_used_percent_code_qualifiers muscle.
5337 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
5338 PERCENT_REQUIRES): Remove.
5339 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
5340 %code "requires" and %code "provides".
5341 * tests/input.at (Reject bad %code qualifiers): New.
5343 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
5345 Use the new code_props interface for destructors and printers.
5346 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
5347 printer_location members, and change the type of the destructor and
5348 printer members to code_props.
5349 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
5350 symbol_printer_get, semantic_type_destructor_set,
5351 semantic_type_printer_set, default_tagged_destructor_set,
5352 default_tagless_destructor_set, default_tagged_printer_set,
5353 default_tagless_printer_set): Use code_props in arguments and return
5354 types in place of char const * and location.
5355 (symbol_destructor_location_get, symbol_printer_location_get): Remove
5356 since the locations are now contained in the return of
5357 symbol_destructor_get and symbol_printer_get.
5358 * src/output.c (symbol_destructors_output, symbol_printers_output):
5360 (symbol_code_props_output): ... this to eliminate duplicate code.
5361 (output_skeleton): Update to use symbol_code_props_output.
5362 * src/reader.c (symbol_should_be_used): Update use of
5363 symbol_destructor_get.
5364 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5365 Update uses of the various _destructor_set and _printer_set functions.
5366 * src/symtab.c: (default_tagged_destructor_location,
5367 default_tagless_destructor_location, default_tagged_printer_location,
5368 default_tagless_printer_location): Remove since we...
5369 (default_tagged_destructor, default_tagless_destructor,
5370 default_tagged_printer, default_tagless_printer): ... change the type
5371 of these to code_props.
5372 (symbol_new, semantic_type_new, symbol_destructor_set,
5373 semantic_type_destructor_set, symbol_destructor_get,
5374 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
5375 symbol_check_alias_consistency, default_tagged_destructor_set,
5376 default_tagless_destructor_set, default_tagged_printer_set,
5377 default_tagless_printer_set): Update.
5378 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
5379 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
5381 (symbol_print): Use SYMBOL_CODE_PRINT.
5383 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
5385 Use the new code_props interface for rule actions.
5386 * src/symlist.h (symbol_list): Replace action, action_location, and
5387 used members with a code_props action_props member.
5388 * src/reader.c (symbol_should_be_used, grammar_rule_check,
5389 grammar_midrule_action, grammar_current_rule_merge_set,
5390 grammar_current_rule_symbol_append, packgram): Update.
5391 * src/scan-code.h (translate_rule_action): Remove, no longer used.
5392 * src/scan-code.l (handle_action_dollar): Update.
5393 (translate_rule_action): Remove, no longer used.
5394 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
5396 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5398 Use the new code_props interface in parse-gram.y.
5399 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
5400 Update all uses of translate_* functions to use the new code_props
5401 interface and to use gram_scanner_last_string_free and
5402 code_scanner_last_string_free where possible.
5403 (grammar_declaration): symbol_list_destructor_set and
5404 symbol_list_printer_set now perform the translation, so don't do it
5405 here. Use gram_scanner_last_string_free where possible.
5406 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
5407 translate_code): Remove, no longer used.
5408 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
5409 symbol_list_printer_set): Perform code translation here rather than
5410 depending on the caller to do so.
5412 * src/symlist.h (struct symbol_list): Correct some documentation typos.
5413 * src/scan-gram.h (gram_last_string): Remove declaration.
5414 * src/scan-gram.l (last_string): Declare it static.
5416 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5418 Encapsulate code properties and related functionality for the various
5419 destructors, printers, and actions into a code_props structure and
5420 interface. This patch merely implements code_props in scan-code.h and
5421 scan-code.l. Future patches will rewrite other modules to use it.
5422 Discussed starting at
5423 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
5424 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
5425 consistently initialize const structs that have an empty location
5427 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
5428 to ensure consistency.
5429 * src/scan-code.h (code_props): New structure.
5430 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
5431 function, macro, and const global variable for initializing a
5432 code_props with no code.
5433 (code_props_plain_init, code_props_symbol_action_init,
5434 code_props_rule_action_init, code_props_translate_code): The rest of
5435 the new code_props functional interface. Among other things, the init
5436 functions set the code_props kind field so that
5437 code_props_translate_code will know whether to behave like
5438 translate_symbol_action, translate_rule_action, or translate_code.
5439 These old translate functions must remain until all other modules are
5440 updated to use the new code_props interface.
5441 (code_scanner_last_string_free): New function similar to
5442 gram_scanner_last_string_free.
5443 (code_scanner_free): Add documentation.
5444 * src/scan-code.l: Implement the new interface.
5445 (code_lex): Make it static, add a code_props* argument, and remove the
5447 (last_string): New static global similar to the one in scan-gram.l.
5448 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
5450 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
5451 code_props since Bison may one day use this information for destructors
5453 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
5454 (handle_action_dollar): Use symbol_list_n_get and set used flag
5455 directly since symbol_list_n_used_set is removed.
5456 (translate_action): Add a code_props* argument and remove the rule,
5457 action, and location arguments. Pass the code_props* on to code_lex.
5458 (translate_rule_action, translate_symbol_action, translate_code):
5459 Rewrite as wrappers around the new code_props interface.
5460 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
5461 it would eventually need to break the encapsulation of code_props.
5463 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5465 * etc/.cvsignore: New.
5467 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5469 Add maintainer-push-check to run maintainer-check using push parsing in
5470 place of pull parsing where available.
5471 * Makefile.am (maintainer-push-check): New.
5472 * data/bison.m4 (b4_use_push_for_pull_if): New.
5473 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
5474 appropriately based on their existing values.
5475 (yypush_parse): Don't print push-parser-specific diagnostics if push
5476 parsing is being used in place of pull parsing.
5477 * data/yacc.c: If push parsing should replace pull parsing, redirect to
5479 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
5480 variable, and insert b4_use_push_for_pull_flag into muscles.
5481 * tests/Makefile.am (maintainer-push-check): New.
5483 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5485 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
5486 (whether successful or failed) so that yypush_parse can be invoked
5487 again to start a new parse using the same yypstate.
5488 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
5489 check multiple yypull_parse invocations on the same yypstate. For pull
5490 mode, extend to check multiple yyparse invocations.
5491 (Exploding the Stack Size with Alloca): Extend to try with
5493 (Exploding the Stack Size with Malloc): Likewise.
5495 * tests/calc.at (Simple LALR Calculator): Don't specify
5496 %skeleton "push.c" since %push-pull-parser implies that now.
5497 * tests/headers.at (export YYLTYPE): Don't check for the push
5498 declarations. Otherwise, this test case can't be used to see if push
5499 mode can truly emulate pull mode.
5500 * tests/input.at (Torturing the Scanner): Likewise.
5501 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
5502 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
5503 AT_YACC_IF, which now includes the case of push mode since %skeleton
5504 need not be used for push mode. This will be more intuitive once
5505 push.c is renamed to yacc.c.
5507 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5509 For push mode, convert yyparse from a macro to a function, invoke yylex
5510 instead of passing a yylexp argument to yypull_parse, and don't
5511 generate yypull_parse or yyparse unless %push-pull-parser is declared.
5512 Discussed starting at
5513 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
5514 * data/bison.m4 (b4_pull_if): New.
5515 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
5516 * data/push.c: Improve M4 quoting a little.
5517 (b4_generate_macro_args, b4_parenthesize): Remove.
5518 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
5519 any time a pull parser is requested.
5520 Don't #define this as a wrapper around yypull_parse. Instead, when
5521 both push and pull are requested, make it a function that does that
5523 (yypull_parse): If there's a b4_prefix, #define this to
5524 b4_prefix[pull_parse] when both push and pull are requested.
5525 Don't define this as a function unless both push and pull are
5527 Remove the yylexp argument and hard-code yylex invocation instead.
5528 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
5530 * src/getargs.c (pull_parser): New global initialized to true.
5531 * getargs.h (pull_parser): extern it.
5532 * src/output.c (prepare): Insert pull_flag muscle.
5533 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
5534 (prologue_declaration): Set both push_parser and pull_parser = true for
5535 %push-pull-parser. Set push_parser = true and pull_parser = false for
5537 * src/scan-gram.l: Don't accept %push_parser as an alternative to
5538 %push-parser since there's no backward-compatibility concern here.
5539 Scan %push-pull-parser.
5540 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
5541 instead of %push-parser.
5542 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
5543 prototype it in the module that calls yyparse.
5544 * tests/input.at (Torturing the Scanner): Likewise.
5545 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
5547 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
5549 Update etc/bench.pl. Optimize push mode a little (the yyn change
5550 deserves most of the credit).
5551 * Makefile.am (SUBDIRS): Add etc subdirectory.
5552 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
5553 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
5554 yytoken, yyval, and yyloc declarations to...
5555 (yyparse or yypush_parse): ... here to improve performance. For
5556 yypush_parse invocations after the first, be sure to assign yyn its old
5558 (yypstate_new): Don't bother initializing the yyresult field since the
5559 initial value isn't used.
5560 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
5561 remove the #define that, in push mode, set it to yyps->NAME.
5562 * etc/Makefile.am: New.
5563 * etc/bench.pl: Remove and build it instead from...
5564 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
5565 "tests/bison" from the build directory by default rather than just
5566 invoking "bison" from $PATH.
5567 (calc_grammar): Update push parser code: don't declare yylval globally,
5568 don't define yyparse_wrapper, and don't #define yyparse.
5569 (bench_grammar): Update to check all working combinations of yacc.c,
5570 push.c, impure, pure, pull, and push.
5572 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5574 For push mode, add pull wrappers around yypush_parse.
5575 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
5576 (yypull_parse): New function wrapping yypush_parse.
5577 (yyparse): New #define wrapping yypull_parse.
5578 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
5580 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
5581 prototype yylex in the module that calls yyparse, and don't prototype
5582 yyparse there. Otherwise, the yyparse expansion won't compile.
5583 * tests/input.at (Torturing the Scanner): Likewise.
5585 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5587 Enable push parsers to operate in impure mode. Thus, %push-parser no
5588 longer implies %pure-parser. The point of this change is to move
5589 towards being able to test the push parser code by running the entire
5590 test suite as if %push-parser had been declared.
5591 * data/push.c (yypush_parse): For impure mode, remove the
5592 yypushed_char, yypushed_val, and yypushed_loc arguments.
5593 Instead, declare these as local variables initialized to the global
5594 yychar, yylval, and yylloc.
5595 For the first yypush_parse invocation only, restore the initial values
5596 of these global variables when it's time to read a token since they
5597 have been overwritten.
5598 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
5600 * tests/calc.at (Simple LALR(1) Calculator): Always declare
5601 %pure-parser along with %push-parser since this test case was designed
5602 for pure push parsers.
5603 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
5604 (AT_YACC_OR_PUSH_IF): New.
5605 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
5606 add a note that it's still wrong for some cases (as it has been for a
5608 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
5609 %push-parser no longer implies %pure-parser.
5611 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5613 Remove some unnecessary differences between the pull parser code and
5614 the push parser code. This patch enables yynerrs in push mode.
5615 * data/push.c: Reformat M4 a little.
5616 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
5617 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
5618 because push mode is on. Instead, if pure mode is on, move yynerrs
5620 (b4_declare_parser_state_variables): ... here.
5621 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
5622 to yyps->NAME so it can be used in yypush_parse.
5623 (yypush_parse): Don't omit uses of yynerrs in push mode.
5625 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5627 Fix bug such that the first pushed token's value and location are
5628 sometimes overwritten (sometimes by %initial-action) before being used.
5629 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
5630 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
5631 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
5632 more closely mimic the pull parser logic.
5633 Don't copy the pushed token to yychar, yylval, and yylloc until it's
5634 time to read a token, which is after any initialization of yylval and
5636 (gottoken): Rename label to...
5637 (yyread_pushed_token): ... for clarity and to avoid infringing on the
5640 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5642 Rearrange initialization of the parser state variables so that the
5643 skeleton doesn't have to have a copy for pull mode and another for push
5644 mode. This patch also fixes at least a bug such that yylloc was not
5645 initialized (with b4_location_initial_line and
5646 b4_location_initial_column) upon calling yypush_parse. However, that
5647 initialization now overwrites the first token's location;
5648 %initial-action assigning @$ already did the same thing, and both bugs
5649 will be fixed in a later patch.
5650 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
5651 (b4_declare_parser_state_variables): Remove initialization of yytoken,
5652 yyss, yyvs, yyls, and yystacksize.
5653 (yypstate_new): Remove initialization of some yypstate fields: yystate,
5654 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
5656 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
5657 yyps->NAME so it can be used in yypush_parse.
5658 (yyparse or yypush_parse): For yypush_parse, don't print the
5659 "Starting parse" diagnostic for invocations after the first.
5660 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
5661 yypush_parse, only do it for the first invocation.
5662 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
5663 initialization to occur in yypush_parse but only on the first
5666 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5668 * data/push.c: Add CPP guards around push parser declarations in both
5669 the header and the code file.
5670 In the code file, move the push parser declarations to the same place
5671 they appear in the header file.
5672 Clean up the M4 some, especially the inconsistent underquoting in
5673 some b4_c_function_def and b4_c_function_decl uses.
5675 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5677 Encapsulate the push parser state variables into an M4 macro so the
5678 push skeleton doesn't have to list them again for pull mode's yyparse.
5679 For push mode, remove yypush_parse's local equivalents of these
5680 variables to eliminate unnecessary copying between the two sets at
5681 run-time. This patch also fixes at least a bug related to multiple
5682 %initial-action invocations in push mode.
5683 * data/push.c (b4_declare_parser_variables): Rename to...
5684 (b4_declare_scanner_communication_variables): ... this for clarity and
5686 (b4_declare_yyparse_variables): Remove and move its contents to the one
5687 spot where it was invoked.
5688 (b4_declare_parser_state_variables): New macro containing the parser
5689 state variables required by push mode.
5690 (struct yypstate): Replace all fields but yynew with
5691 b4_declare_parser_state_variables.
5692 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
5693 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
5694 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
5695 (yyparse or yypush_parse): For yyparse in pull mode, replace local
5696 parser state variable declarations with
5697 b4_declare_parser_state_variables.
5698 Don't initialize parser state variables when calling yypush_parse since
5699 yypstate_new already does that.
5700 Invoke the user's initial action only upon the first yypush_parse
5702 Remove all code that copies between the local parser state variables
5705 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5707 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
5708 prevent a name collision in a future patch where these names will
5709 sometimes be #define'd.
5710 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
5711 since it no longer has the same name as the existing argument.
5712 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
5714 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
5715 and Joel E. Denny <jdenny@ces.clemson.edu>
5717 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
5718 that the argument is case-insensitive, and there's no `=' here.
5719 For the %skeleton entry, mention that %language is better.
5720 (Bison Options): Likewise for --language and --skeleton. Move the
5721 --skeleton entry so that the `Tuning the parser' section is sorted
5722 alphabetically on long options.
5723 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
5724 %language directive in detail here; cross-reference the %language
5725 documentation instead.
5726 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
5727 `%require "2.3b"' so that the example is always up-to-date.
5728 (Table of Symbols): Add entries for %language and %skeleton.
5729 * examples/extexi (normalize): Instead of replacing every %require
5730 argument with the current Bison version, just substitute for
5731 `@value{VERSION}'. This guarantees that we're testing what actually
5732 appears in the documentation.
5733 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
5734 rather than `@VERSION@'.
5736 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5738 * NEWS: Reword the %language news a bit, and put it earlier.
5740 * src/getargs.c (skeleton_arg): Last arg is now location const *.
5741 Rewrite to simplify the logic.
5742 (language_argmatch): Likewise.
5743 (program_name): We now own this var.
5744 * src/getargs.h (struct bison_language): Use char[] rather than
5747 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
5749 * src/complain.c (program_name): Remove decl; no longer needed.
5750 * src/main.c (program_name): Remove; now belongs to getargs.
5752 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
5754 * NEWS: Document %language.
5756 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
5758 * data/c-skel.m4, data/c++-skel.m4: New files.
5759 * data/glr.c: Complain on push parsers.
5761 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
5763 (Decl Summary): Document %language and %skeleton.
5764 (Command line): Document -L.
5766 * examples/extexi: Rewrite %require directive.
5767 * examples/calc++/Makefile.am: Pass VERSION to extexi.
5769 * src/files.c (compute_exts_from_gc): Look in language structure
5771 (compute_file_name_parts): Check whether .tab should be added.
5772 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
5773 (language, skeleton_arg, language_argmatch): New.
5774 (long_options): Add --language.
5775 (getargs): Use skeleton_arg, add -L/--language.
5776 * src/getargs.h: Include location.h.
5777 (struct bison_language, language, skeleton_arg, language_argmatch): New.
5778 * src/output.c (prepare): Pick default skeleton from struct language.
5779 Don't dispatch C skeletons here.
5780 * src/parse-gram.y (PERCENT_LANGUAGE): New.
5781 (prologue_declaration): Add "%language" rule, use skeleton_arg.
5782 * src/scan-gram.l ("%language"): New rule.
5784 * tests/calc.at: Test %skeleton and %language.
5785 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
5786 (AT_GLR_IF): Look for %skeleton "glr.cc".
5787 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
5788 (AT_YACC_IF): Reject %language.
5790 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5792 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5793 since it wasn't used; only the typedef name 'semantic_type' is needed.
5794 Also, omit trailing white space.
5796 * bootstrap: Sync from coreutils.
5797 (gnulib_extra_files): Add build-aux/announce.gen.
5798 (slurp): Adjust .gitignore files like .cvsignore files.
5799 * build-aux/announce-gen: Remove from CVS, since bootstrap
5802 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5804 Make %push-parser imply %pure-parser. This fixes several bugs; see
5805 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5806 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5808 * data/push.c: Don't bother testing b4_push_if when deciding whether
5809 to expand b4_declare_parser_variables globally.
5810 (yypush_parse): Likewise in here.
5812 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5813 (yy_reduce_print): Reformat M4 for readability.
5815 2006-12-15 Bob Rossi <bob@brasko.net>
5816 and Joel Denny <jdenny@ces.clemson.edu>
5818 * data/push.c (yypstate): Add typedef, and update all uses of
5819 struct yypstate to just yypstate.
5820 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5822 2006-12-14 Bob Rossi <bob@brasko.net>
5824 * data/push.c (yypush_parse): Declare prototype regardless of
5827 2006-12-14 Bob Rossi <bob@brasko.net>
5829 * data/push.c (yyparse): Remove the prototype and the #define when in
5832 2006-12-13 Bob Rossi <bob@brasko.net>
5834 * data/push.c (yypstate_init): Rename to...
5835 (yypstate_new): ... this and use b4_c_function_def.
5836 (yypstate_delete): New.
5837 (yypush_parse): Change parameters yynval and yynlloc to be const.
5838 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5839 yypstate_delete functions.
5841 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5843 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5844 strange test case titles. Reported by Bob Rossi.
5846 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5848 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5849 of potential ambiguities in GLR grammers.
5851 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5853 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5854 `bison ', use m4_index instead of m4_substr since chopping up a string
5855 containing M4-special characters causes problems here.
5857 Fix a couple of bugs related to special characters in user-specified
5858 file names, and make it easier for skeletons to compute output file
5859 names with the same file name prefix as Bison-computed output file
5861 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5862 b4_parser_file_name and b4_spec_defines_file instead of
5863 @output_parser_name@ and @output_header_name@, which are now redundant.
5864 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5865 b4_parser_file_name, b4_spec_defines_file, and the new
5866 @basename(FILENAME@) instead of @output_parser_name@ and
5867 @output_header_name@, which inappropriately escaped the file names as
5869 * src/files.c (all_but_ext): Remove static qualifier.
5870 (compute_output_file_names): Move `free (all_but_ext)' to...
5871 (output_file_names_free): ... here since all_but_ext is needed later.
5872 * src/files.h (all_but_ext): Extern.
5873 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5874 exactly what MUSCLE_INSERT_STRING used to do.

5876 characters are escaped properly.
5877 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5879 For pkgdatadir muscle, maintain previous functionality by using
5880 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5881 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5882 digraphs would never be expanded. Hopefully no one has M4-special
5883 characters in his Bison installation path.
5884 * src/scan-skel.l: Don't parse @output_header_name@ and
5885 @output_parser_name@ anymore since they're now redundant.

5896 conflict with other output files.
5897 * data/glr.c: Don't generate the header file here when glr.cc does.
5898 * src/files.c (file_names, file_names_count): New static globals.
5899 (compute_output_file_names): Invoke output_file_name_check for files
5900 not generated by the skeletons and remove existing checks.
5901 (output_file_name_check): New function that warns about conflicting
5903 (output_file_names_free): Free file_names.
5904 * src/files.h (output_file_name_check): Declare.

5927 and Joel Denny <jdenny@ces.clemson.edu>
5929 * data/push.c (yypvarsinit): Change return type from void* to struct
5930 yypvars*. No longer cast to void* on return.
5931 (struct yypvars): Remove yylen since it need not be remembered between
5932 yypushparse invocations.
5933 (yypushparse): Don't copy between yylen and pv->yylen.
5935 2006-12-05 Bob Rossi <bob@brasko.net>
5937 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.

5985 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
5986 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
5987 Remove the `=' from %output.
5989 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>

6031 grammar is maintained with Bison's highest standards.
6032 * src/getargs.c: Fix some typos in Doxygen comments.

6037 later. Reported by Paul Eggert in
6038 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
6039 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
6040 * src/scan-code.l (translate_action): Don't bother invoking
6041 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
6042 (code_scanner_free): Instead of invoking

6051 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
6052 has been called previously for the same key.
6053 (muscle_find): Return storage instead of value so that
6054 --enable-gcc-warnings doesn't produce warnings that the return discards
6055 const. aver that the value and storage are the same since storage
6056 could potentially be NULL when value is not.
6057 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
6060 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6062 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
6063 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives

6084 src_extension, and header_extension.

6102 add a new `char *code' member.
6103 ("{...}"): Declare semantic type as code.
6104 * src/scan-code.h (translate_rule_action):
6105 (translate_symbol_action, translate_code, translate_action): Return
6106 `char const *' rather than `char *' since external code should not free
6108 * src/scan-code.l: Likewise.
6109 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
6110 which is "{...}" in the parser.

6116 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
6117 expecting a non-zero exit status sets --leak-check=summary and
6118 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
6119 this case, and we don't want to hear about it.
6121 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6123 * bootstrap (runtime-po/Makevars): Derive from po/Makevars

6166 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
6168 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
6169 the parser header file so that gcc doesn't warn.
6171 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

6221 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
6222 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
6223 like $@n instead of just @n so that the default %destructor/%printer
6224 logic doesn't see them as user-defined symbols.
6225 (symbol_is_dummy): Check for both forms of the name.
6226 * src/reader.c (packgram): Remove the `$' from each midrule symbol

6321 (slurp): Call it here, in place of CVS-specific code.
6323 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
6325 Fix testsuite for ./configure --enable-gcc-warnings:
6326 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
6327 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
6328 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
6329 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
6330 * test/regression.at (Diagnostic that expects two alternatives):
6333 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
6335 * bootstrap.conf (gnulib_modules): Add config-h.
6336 * djgpp/subpipe.c: Include <config.h> unconditionally; don't
6337 worry about HAVE_CONFIG_H.
6338 * lib/abitset.c: Likewise.
6339 * lib/bitset.c: Likewise.
6340 * lib/bitset_stats.c: Likewise.
6341 * lib/bitsetv-print.c: Likewise.
6342 * lib/bitsetv.c: Likewise.

6352 * lib/bitsetv.c: Include "bitsetv.h" first.
6353 * lib/get-errno.c: Include "get-errno.h" first.
6354 * m4/.cvsignore: Add config-h.m4.
6355 * tests/actions.at (Default %printer and %destructor for ...):
6356 Adjust expected line numbers in output to reflect removal of #if
6357 HAVE_CONFIG_H lines.
6358 * tests/glr-regression.at (Missed %merge type warnings when ...):
6360 * tests/regression.at (Braced code in declaration in rules section):

6363 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
6364 Include <config.h> unconditionally.
6366 * bootstrap: Sync from coreutils, as follows:
6368 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
6370 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
6371 variable was sometimes used without being initialized. This
6372 messed up the installation of the INSTALL file in some cases.
6374 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
6376 * bootstrap (usage, main program, symlink_to_gnulib): Add option
6377 --copy. Inspired by a suggestion from Bruno Haible.
6379 2006-10-03 Jim Meyering <jim@meyering.net>
6381 * bootstrap: Undo last change to this file, since now gnulib-tool
6382 sticks with the automake default in generating dependencies.
6384 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
6386 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
6387 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
6389 * doc/bison.1: Add copyright notice.
6391 * data/glr.c: Don't include <stdarg.h>; not used.

6395 * doc/bison.1: Likewise.
6396 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
6397 * THANKS: Add Satya Kiran Popuri, who proposed the initial version

6410 * src/print_graph.c: Include graphviz.h rather than vcg.h.
6411 (static_graph, fgraph): Remove. All uses changed to pass
6412 arguments instead of sharing a static var.
6413 (print_core, print_actions, print_state, print_graph):
6414 Output graphviz format rather than VCG format.
6415 * tests/.cvsignore: Remove *.vcg; add *.dot.
6416 * tests/output.at: Expect *.dot files, not *.vcg files.
6418 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
6419 accommodates the 2006-10-08 change.
6421 2006-10-11 Bob Rossi <bob@brasko.net>
6423 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.
6424 (b4_yyssa, b4_yyerror_range): New macros.
6425 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
6426 (yypvarsinit): Remove init of removed fields.
6427 (yypushparse): Remove use of removed fields; use new macros instead.
6429 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
6431 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
6432 in a push parser. Reindent slightly to match yacc.c better.
6434 2006-10-11 Bob Rossi <bob@brasko.net>
6436 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
6438 (yypvarsinit, yypushparse): Remove init of removed fields.

6441 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
6443 * THANKS: Add Paolo Bonzini and Bob Rossi.
6445 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
6447 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
6448 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
6449 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
6450 b4_define_user_cde and uses): Remove.
6451 (b4_comment, b4_prefix, b4_sync_start): New.
6452 * data/bison.m4: New file, with most of the content removed from c.m4.
6453 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
6454 * src/output.c (output_skeleton): Pass bison.m4.
6455 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
6458 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
6460 Fix test failure reported by Tom Lane in
6461 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
6462 and try to make such failures easier to catch in the future.
6463 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
6464 that's now the caller's responsibility.
6465 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
6466 Set yychar = YYEOF if it's negative.
6467 * tests/actions.at (yylex): Abort if asked to read past EOF.

6473 * tests/torture.at (yylex): Likewise.
6475 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
6477 Fix problems with translating English-language diagnostics.
6478 * bootstrap: Fix bug introduced in recent bootstrap changes, with
6479 respect to bison-runtime pot generation. The YY_ stuff
6480 wasn't being captured.
6481 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
6482 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
6483 * runtime-po/POTFILES.in: Add data/push.c.
6485 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
6487 Merge bootstrap changes from coreutils.
6489 2006-09-28 Jim Meyering <jim@meyering.net>
6491 Automatically generated dependencies are important even
6492 when all of the sources in a directory come from gnulib.
6493 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
6494 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
6496 2006-09-23 Jim Meyering <jim@meyering.net>
6498 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
6500 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6502 * bootstrap: Add support for --force.
6503 (usage): New function. Describe usage less tersely.
6504 (CVS_only_file): New var.

6508 * data/push.c (YYPUSH_MORE): Make it an enum instead.
6509 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.

6512 2006-09-20 Bob Rossi <bob@brasko.net>
6514 * data/push.c (yyresult_get): Remove function.
6515 (YYPUSH_MORE): Add #define.
6516 (yypushparse): Modify return value.
6518 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6520 * stamp-h.in: Remove; no longer needed.
6521 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
6522 Remove config.h, config.hin, intl (no longer created).
6523 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
6526 Sync bootstrap from coreutils, as follows:
6528 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
6530 * bootstrap (symlink_to_gnulib): New function.
6531 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
6532 to copies-of-gnulib.
6533 (cp_mark_as_generated, slurp, gnulib_files):
6534 Avoid making a copy if it's the same as the old version.
6535 (gnulib_files): Add support for this variable (used by Bison).
6537 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6539 * src/getargs.c (usage): Rework to use conventions similar to
6540 coreutils, to make translation a bit easier and the code a bit
6541 smaller. Problem reported by Tim Van Holder.
6543 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
6545 Use some of gnulib's new modules, taken from coreutils.
6547 * bootstrap: Sync from coreutils, except add support for gnulib_files.
6548 * bootstrap.conf: New file.
6549 (gnulib_modules): Add configmake, inttypes, unistd.
6550 (XGETTEXT_OPTIONS): Add complain, complain_at,
6551 fatal, fatal_at, warn, warn_at, unexpected_end.
6552 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
6553 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
6555 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
6557 (GNULIB_AUTOCONF_SNIPPET): Remove.
6558 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
6560 * lib/.cvsignore: Add inttypes_.h.
6561 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
6562 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
6563 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
6564 no-longer-necessary initializations.
6565 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
6566 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
6567 use the unistd module.
6568 * src/system.h: Likewise.
6569 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
6570 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
6571 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
6572 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
6573 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
6574 * src/system.h: Include inttypes.h unconditionally, now that we
6575 use the inttypes module. Don't bother to include stdint.h, since
6576 inttypes.h now does that for us.
6577 (LOCALEDIR): Remove, now that we use the configmake module.
6578 * src/getargs.c: Include configmake.h.
6579 * src/main.c: Likewise.
6580 * src/output.c: Likewise.
6581 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
6582 not from $abs_top_builddir, since config.h moved.
6585 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
6586 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
6588 * src/parse-gram.y (symbol_declaration): Don't put statements
6589 before declarations; it's not portable to C89.
6590 * src/scan-code.l (handle_action_at): Likewise.
6592 * src/scan-code.l: Always initialize braces_level; the old code
6593 left it uninitialized and therefore had undefined behavior.
6595 Don't attempt to redefine 'assert', since it runs afoul of
6596 systems where standard headers (mistakenly) include <assert.h>.
6597 Instead, define and use our own alternative, called 'aver'.
6598 * src/reader.c: Don't include assert.h, since we no longer
6600 * src/scan-code.l: Likewise.
6601 * src/system.h (assert): Remove, replacing with....
6602 (aver): New function, taking a bool arg. All uses changed.
6603 * src/tables.c (pack_vector): Ensure that aver arg is bool,
6604 not merely an integer.
6606 2006-09-15 Bob Rossi <bob@brasko.net>
6608 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
6609 * data/c.m4 (YYPUSH): New.
6610 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
6611 * src/getargs.c (push_parser): New var.
6612 * src/getargs.h (push_parser): New declaration.
6613 * src/output.c (prepare): Add macro insertion of `push_flag'.
6614 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
6615 (prologue_declaration): Parse %push-parser.
6616 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
6617 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
6618 list of removed lines from the traces observed.
6619 (AT_CHECK_CALC_LALR): Added push parser tests.
6621 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
6623 * NEWS: Version 2.3a.
6624 * configure.ac (AC_INIT): Likewise.
6626 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
6627 "#define YYSTYPE int" that caused "make maintainer-check" to fail
6628 due to header ordering dependencies. I don't know why the #define
6631 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
6632 runtime cost when YYDEBUG is not defined, and so that some tests
6633 that used to fail now work. Problem and initial suggestion by
6635 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
6636 * data/glr.cc (b4_parser_class_name):
6637 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
6638 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
6639 (yydebug_) [YYDEBUG]: New member.
6640 (yycdebug_): Now defined only if YYDEBUG.
6641 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
6642 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
6643 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
6645 (debug_stream, set_debug_stream, debug_level, set_debug_level):
6646 Define only if YYDEBUG.
6647 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
6649 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
6650 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
6651 AT_CHECK_CALC_GLR_CC that are working now.
6653 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
6655 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
6656 We don't need them in glr.cc, and glr.c defines them.
6657 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
6658 assumes that defining it to anything is the same as defining
6659 it to 1. Problem reported by Paolo Bonzini.
6661 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
6663 * data/c.m4 (b4_null, b4_case): Define.
6664 * src/output.c (prepare_symbols): Use b4_null.
6665 (user_actions_output): Use b4_case.
6667 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
6669 * data/glr.c (b4_shared_declarations): Put start-header first,
6670 before any #includes that we generate, so that feature-test
6671 macros work. Problem reported by Michael Deutschmann in
6672 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
6673 * data/lalr1.cc: Likewise.
6674 * doc/bison.texinfo (Prologue): Document that feature-test macros
6675 should be defined before any Bison declarations.
6676 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
6677 that depend on location.hh after, not before, Bison decls, since
6678 we now include location.hh after the first user prologue.
6680 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
6681 Sander Brandenburg in
6682 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
6683 Also, fix minor white space and comment issues.
6684 (Prologue): Mention that it's better to define feature-test macros
6685 before Bison declarations. Problem reported by Michael Deutschmann.
6687 * README-cvs: Fix typo: "&" should be "&&". Problem reported
6689 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
6690 This adjusts to recent gnulib changes.
6692 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6694 Finish implementation of per-type %destructor/%printer. Discussed
6696 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
6698 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
6699 * NEWS (2.3+): Add a description of this feature to the default
6700 %destructor/%printer description.
6701 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
6702 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6703 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
6704 list node contains a semantic type.
6705 * src/symtab.c, src/symtab.h: Extend with a table that associates
6706 semantic types with their %destructor's and %printer's.
6707 (semantic_type_from_uniqstr, semantic_type_get,
6708 semantic_type_destructor_set, semantic_type_printer_set): New functions
6709 composing the public interface of that table.
6710 (symbol_destructor_get, symbol_destructor_location_get,
6711 symbol_printer_get, symbol_printer_location_get): If there's no
6712 per-symbol %destructor/%printer, look up the per-type before trying
6714 * tests/actions.at (Per-type %printer and %destructor): New test case.
6715 * tests/input.at (Default %printer and %destructor redeclared):
6716 Extend to check that multiple occurrences of %symbol-default in a
6717 single %destructor/%printer declaration is an error.
6718 (Per-type %printer and %destructor redeclared, Unused values with
6719 per-type %destructor): New test cases.
6721 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6723 Require default %destructor/%printer to be declared using
6724 %symbol-default instead of an empty symbol list, and start working on
6725 new per-type %destructor/%printer. Discussed at
6726 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
6727 * NEWS (2.3+): Add %symbol-default to example.
6728 * bison.texinfo (Freeing Discarded Symbols): Likewise.
6729 (Table of Symbols): Add entry for %symbol-default.
6730 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
6731 (generic_symlist, generic_symlist_item): New nonterminals for creating
6732 a list in which each item is a symbol, semantic type, or
6734 (grammar_declaration): Use generic_symlist in %destructor and %printer
6735 declarations instead of symbols.1 or an empty list.
6736 (symbol_declaration, precedence_declaration, symbols.1): Update actions
6737 for changes to symbol_list.
6738 * src/reader.c: Update for changes to symbol_list.
6739 * src/scan-code.l: Likewise.
6740 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
6741 * src/symlist.c, src/symlist.h: Extend such that a list node may
6742 represent a semantic type or a %symbol-default in addition to just an
6743 ordinary symbol. Add switched functions for setting %destructor's and
6745 * tests/actions.at, tests/input.at: Add %symbol-default to all default
6746 %destructor/%printer declarations.
6748 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
6750 Whether the default %destructor/%printer applies to a particular symbol
6751 isn't a question of whether the user *declares* that symbol (in %token,
6752 for example). It's a question of whether the user by any means
6753 *defines* the symbol at all (by simply using a char token, for
6754 example). $end is defined by Bison whereas any other token with token
6755 number 0 is defined by the user. The error token is always defined by
6756 Bison regardless of whether the user declares it with %token, but we
6757 may one day let the user define error as a nonterminal instead.
6758 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6759 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
6760 the meaning of "user-defined".
6761 * tests/actions.at (Default %printer and %destructor for user-declared
6762 end token): Rename to...
6763 (Default %printer and %destructor for user-defined end token): ...
6766 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
6767 computation of whether to apply the default, don't maintain a list of
6768 every Bison-defined symbol. Instead, just check for a first character
6769 of '$', which a user symbol cannot have, and check for the error token.
6771 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
6773 Don't apply the default %destructor or %printer to the error token,
6774 $undefined, or $accept. This change fits the general rule that the
6775 default %destructor and %printer are only for user-declared symbols,
6776 and it solves several difficulties that are described in the new test
6778 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
6779 * tests/actions.at (Default %printer and %destructor are not for error
6780 or $undefined, Default %printer and %destructor are not for $accept):
6783 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
6785 Allow %start after the first rule.
6786 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
6787 when parsing the first rule.
6788 (check_and_convert_grammar): Search for it here after all grammar
6789 declarations have been parsed. Skip midrules, which have dummy LHS
6791 * src/symtab.c (symbol_is_dummy): New function.
6792 * src/symtab.h (symbol_is_dummy): Declare it.
6793 * tests/input.at (%start after first rule): New test.
6795 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6797 Redo some of the previous commit: add back the ability to use
6798 non-aliased/undeclared string literals since it might be useful to
6799 those declaring %token-table.
6800 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6801 commit: don't worry about complaints from symbols_pack.
6802 * src/symtab.c (symbol_new, symbol_class_set,
6803 symbol_check_alias_consistency): Undo changes in previous commit: count
6804 each string literal as a new symbol and token, assign it a symbol
6805 number, and don't complain about non-aliased string literals.
6806 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6807 and token counts but does still set aliased tokens to the same number,
6808 symbol_pack_processor now leaves empty slots in the symbols array.
6810 * tests/regression.at (Undeclared string literal): Remove test case
6811 added in previous commit since non-aliased string literals are allowed
6813 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6814 remove unnecessary string literal declarations.
6815 * tests/sets.at (Firsts): Likewise.
6817 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6819 Don't allow an undeclared string literal, but allow a string literal to
6820 be used before its declaration.
6821 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6822 symbols_pack complained.
6823 * src/symtab.c (symbol_new): Don't count a string literal as a new
6825 (symbol_class_set): Don't count a string literal as a new token, and
6826 don't assign it a symbol number since symbol_make_alias does that.
6827 (symbol_make_alias): It's not necessary to decrement the symbol and
6828 token counts anymore. Don't assume that an alias declaration occurs
6829 before any uses of the identifier or string, and thus don't assert that
6830 one of them has the highest symbol number so far.
6831 (symbol_check_alias_consistency): Complain if there's a string literal
6832 that wasn't declared as an alias.
6833 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6834 symbol_pack asserts that every token has been assigned a symbol number
6835 although undeclared string literals have not.
6836 * tests/regression.at (String alias declared after use, Undeclared
6837 string literal): New test cases.
6838 (Characters Escapes, Web2c Actions): Declare string literals as
6840 * tests/sets.at (Firsts): Likewise.
6842 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6844 In the grammar scanner, STRING_FINISH unclosed constructs and return
6845 them to the parser in order to improve error messages.
6846 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6847 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6848 * tests/input.at (Unclosed constructs): New test case.
6849 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6852 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6855 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6857 Handle string aliases for character tokens correctly.
6858 * src/symtab.c (symbol_user_token_number_set): If the token has an
6859 alias, check and set its alias's user token number instead of its own,
6860 which is set to indicate the alias. Previously, every occurrence of
6861 the character token in the grammar overwrote that alias indicator with
6863 * tests/input.at (String aliases for character tokens): New test.
6865 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6867 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6869 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6871 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6872 to prevent failures when building on older platforms.
6873 Check for autopoint failure.
6874 Set XGETTEXT_OPTIONS to values that check for C format strings,
6875 so that translators are warned about them (this also helps
6876 prevent core dumps).
6878 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6879 function, since it simplifies our code a bit.
6881 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6882 rather than -W, so we don't get bogus warnings about sign comparisons.
6883 Add -Wpointer-arith, since that warning is useful (it reports code
6884 that does not conform to C89 and that some compilers reject).
6885 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6886 since it's no longer needed.
6888 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6890 Clean up scanners a bit.
6891 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6892 definitions so gcc won't warn when obstack_for_string is unused.
6893 * src/scan-code.l: config.h and system.h are already #include'd by
6894 scan-code-c.c, so get rid of them here.
6895 * src/scan-gram.l: Likewise.
6896 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6897 definitions rather than duplicating the rest of it.
6898 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6900 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6902 Suppress signed/unsigned comparison warnings for yycheck.
6903 * data/c.m4 (b4_safest_int_type): New macro.
6904 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6905 a signed int type, cast it to b4_safest_int_type first.
6906 * data/yacc.c: Likewise.
6907 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6910 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6912 * doc/bison.texinfo: Fix some typos.
6914 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6916 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6917 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6919 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6920 the latest gnulib does this a different way.
6921 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6922 translation was patched, so stop omitting it.
6924 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6926 Enable declaration of default %printer/%destructor. Make the parser
6927 use these for all user-declared grammar symbols for which the user does
6928 not declare a specific %printer/%destructor. Thus, the parser uses it
6929 for token 0 if the user declares it but not if Bison generates it as
6930 $end. Discussed starting at
6931 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6932 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6934 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6935 * NEWS (2.3+): Mention.
6936 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
6937 declare a %destructor for a mid-rule's semantic value. It's just
6938 impossible to declare one specific to it.
6939 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
6940 code. Describe default %destructor form.
6941 * src/parse-gram.y (grammar_declaration): Parse default
6942 %printer/%destructor declarations.
6943 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
6944 and symbol_destructor_location_get rather than accessing the destructor
6945 and destructor_location members of struct symbol.
6946 (symbol_printers_output): Likewise but for %printer's.
6947 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
6949 * src/symtab.c (default_destructor, default_destructor_location,
6950 default_printer, default_printer_location): New static global
6951 variables to record the default %destructor and %printer.
6952 (symbol_destructor_get, symbol_destructor_location_get,
6953 symbol_printer_get, symbol_printer_location_get): New functions to
6954 compute the appropriate %destructor and %printer for a symbol.
6955 (default_destructor_set, default_printer_set): New functions to set the
6956 default %destructor and %printer.
6957 * src/symtab.h: Prototype all those new functions.
6958 * tests/actions.at (Default %printer and %destructor): New test to
6959 check that the right %printer and %destructor are called, that they're
6960 not called for $end, and that $$ and @$ work correctly.
6961 (Default %printer and %destructor for user-declared end token): New
6962 test to check that the default %printer and %destructor are called for
6963 a user-declared end token.
6964 * tests/input.at (Default %printer and %destructor redeclared, Unused
6965 values with default %destructor): New tests to check related grammar
6966 warnings and errors.
6968 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6970 Clean up handling of %destructor for the end token (token 0).
6971 Discussed starting at
6972 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
6974 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
6976 Make the skeletons consistent in how they pop the end token and invoke
6978 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
6979 state, which has token number 0, since this would invoke the
6980 %destructor for the end token.
6981 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
6982 until after shifting the end token, or else it won't be popped.
6983 * data/yacc.c (yyparse): Likewise.
6985 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
6986 it's the end token. Upon termination, destroy an unshifted lookahead
6987 even when it's the end token.
6988 * data/lalr1.cc (yy::parser::parse): Likewise.
6989 * data/yacc.c (yyparse): Likewise.
6991 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
6992 value warnings for the end token when the user gives the end token a
6995 * tests/actions.at (Printers and Destructors): Test all the above.
6997 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
6999 Update to latest gnulib and gettext versions.
7000 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
7002 (gnulib_files): Add m4/warning.m4. Don't worry about files
7003 overwritten by autopoint.
7004 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
7005 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
7007 Don't use autoreconf; instead, invoke autopoint etc. by hand,
7008 so that we can remove the intl files at a better time.
7009 (intl_files_to_remove): Remove aclocal.m4, since it gets
7010 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
7011 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
7012 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
7013 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
7014 Remove datarootdir hack; no longer needed.
7015 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
7016 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
7017 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
7019 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
7020 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
7022 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7024 * bootstrap: Adjust to today's change to gnulib-tool by invoking
7025 it with --assume-autoconf='latest-stable'.
7027 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
7029 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
7030 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
7032 * src/muscle_tab.h (muscle_grow): Replace the header comments with
7033 those from muscle_tab.c since the old ones are misleading.
7035 2006-07-13 Akim Demaille <akim@epita.fr>
7037 Support %define "KEY" {VALUE}.
7038 * src/scan-code.h, src/scan-code.l (translate_action)
7039 (translate_rule_action, translate_symbol_action, translate_code):
7040 Return char *, not const char *.
7041 * src/parse-gram.y (declaration): Rename as...
7042 (prologue_declaration): this.
7043 (string_content): Remove this nonterminal, use STRING.
7044 (braceless, content, content.opt): New nonterminal.
7046 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
7048 * src/scan-gram.l (getargs.h): Don't include it.
7050 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
7052 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
7053 rather than a for-loop that declares a local bool variable. This
7054 should work around a compatibility problem with a Cray x1e C++
7055 compiler reported by Hung Nguyen in
7056 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
7057 The for-loop was introduced in the 2004-11-17 change but I don't
7058 know why it was needed.
7060 2006-07-12 Akim Demaille <akim@epita.fr>
7062 * data/c.m4: Comment changes.
7064 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
7066 * src/complain.c (error_message, ERROR_MESSAGE): New.
7068 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
7069 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
7071 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
7073 * NEWS: Instead of %union, you can define and use your own union type
7074 YYSTYPE if your grammar contains at least one <type> tag.
7075 Your YYSTYPE need not be a macro; it can be a typedef.
7076 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
7077 (Union Decl, Decl Summary): Document this.
7078 * data/glr.c (YYSTYPE): Implement this.
7079 * data/glr.cc (YYSTYPE): Likewise.
7080 * data/lalr1.cc (YYSTYPE): Likewise.
7081 * data/yacc.c (YYSTYPE): Likewise.
7082 * src/output.c (prepare): Output tag_seen_flag.
7083 * src/parse-gram.y (declaration, grammar_declaration):
7084 Use 'union_seen' rather than 'typed' to determine whether
7085 %union has been seen, since grammars can now be typed without
7087 (symbol_declaration, type.opt, symbol_def):
7088 Keep track of whether a tag has been seen.
7089 * src/reader.c (union_seen, tag_seen): New vars.
7091 * src/reader.h (union_seen, tag_seen, typed): Likewise.
7092 * src/scan-code.l (untyped_var_seen): New variable.
7093 (handle_action_dollar): Adjust to above changes.
7094 (handle_action_dollar, handle_action_at):
7095 Improve overflow checking for outlandish numbers.
7096 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
7097 avoid new diagnostics generated by above changes.
7098 * tests/regression.at (YYSTYPE typedef): Add test to check
7099 for type tags without %union.
7101 * src/symlist.c (symbol_list_length): Return int, not unsigned
7102 int, since callers expect int. This may need to get revisited
7103 once we have proper integer overflow checking.
7105 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
7106 object is now static.
7108 * src/getargs.c (flags_argmatch): Return void, not int,
7109 to pacify ./configure --enable-gcc-warnings.
7111 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
7112 since last_string is already defined to FLEX_PREFIX (last_string).
7114 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
7116 Implement --warnings/-W.
7117 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
7119 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
7121 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
7122 (warnings_args, warnings_types): New.
7123 (getargs, short_options, long_options): Accept -W/--warnings.
7124 Sort the options by alphabetical order, upper case letter right
7125 before its lower case.
7127 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
7129 Change %merge result type clash warnings to errors. Discussed at
7130 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
7131 * src/reader.c (record_merge_function_type): Use complain_at.
7132 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7133 declared later): Update test case results.
7135 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
7137 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
7138 to be in alphabetical order.
7139 (trace_args): Spelling fixes.
7141 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
7143 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
7144 so they don't collide with user-defined macros.
7145 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
7146 this was never guaranteed, and now that we're using gnulib stdint,
7147 which defines int_fast16_t to long int, the problem is exposed.
7149 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
7151 * data/c.m4 (b4_basename): Simplify a bit, since we don't
7152 need the full POSIX semantics (and weren't implementing them
7155 Adjust to Autoconf 2.60 and today's gnulib.
7156 * bootstrap (gnulib_modules): Add stdint.
7157 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
7158 no longer copies it.
7159 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
7160 since stdint needs the former and wcwidth (which is now required
7161 by mbswidth) needs the latter.
7162 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
7163 work around a compatibility glitch between gettext 0.14.6 and
7165 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
7166 Do not check for uintptr_t, since new stdint module does the right
7168 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
7169 Add stdint.h, stdint_.h, wcwidth.h.
7170 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
7171 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
7172 stdint.m4, wchar_t.m4, wcwidth.m4.
7173 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
7174 usual order for ../lib/*.h files.
7175 (file_name_split): Use last_component, not base_name, to adjust
7177 * src/parse-gram.h: Include <strverscmp.h> in the usual order
7178 for ../lib/*.h files.
7179 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
7180 Define unconditionally, since we now assume the stdint module.
7181 * src/scan-skel.l: Include <dirname.h>.
7182 (BASE_QPUTS): Use last_component, not base_name.
7183 * src/system.h: Include <unlocked-io.h> in the usual order
7184 for ../lib/*.h files. Include <stdint.h> unconditionally,
7185 since we now use the stdint module.
7186 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
7187 HAVE_UINTPTR_T, since we now use the stdint module.
7188 (base_name): Remove decl, since files now include <dirname.h>
7191 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
7193 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
7195 * data/yacc.c, data/glr.c, data/location.cc: Use them.
7196 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
7198 * tests/calc.at: Adjust.
7200 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
7202 * data/c.m4 (b4_basename): New.
7203 (b4_syncline): Also output the location of its invocation (from
7205 (b4_user_action, b4_define_user_action, b4_user_actions)
7206 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
7207 (b4_user_stype): New.
7208 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
7210 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
7212 In the grammar file, the first column is 1 not 0 on the first line as
7213 on every other line.
7214 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
7215 * tests/input.at (Torturing the Scanner): Update output.
7217 * src/scan-gram.l (scanner_cursor): Declare it static.
7219 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
7221 In warnings, say "previous declaration" rather than "first
7223 * src/symtab.c (redeclaration): Do that here.
7224 * src/reader.c (record_merge_function_type): In the case of a result
7225 type clash, report the previous declaration rather than the very first
7226 one in the grammar file.
7227 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7228 declared later): Add a third declaration to check this behavior.
7229 * tests/input.at (Incompatible Aliases): Update output.
7231 2006-06-27 Akim Demaille <akim@epita.fr>
7233 * doc/Doxyfile.in: New.
7234 * doc/Makefile.am: Use it.
7235 * src/lalr.h, src/symtab.h: Initial doxygenation.
7237 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7239 Don't miss %merge result type warnings just because the LHS types are
7240 declared after the %merge. This continues the effort of the previous
7242 * src/reader.c (get_merge_function): Don't set the merger type yet.
7243 (record_merge_function_type): New function for setting the merger type
7244 and checking for clashes.
7245 (grammar_current_rule_merge_set): Set the location of the %merge for
7247 (packgram): Invoke record_merge_function_type for each rule now that
7248 all symbol type declarations have been parsed.
7249 * src/reader.h (merger_list.type_declaration_location): New member
7250 storing the location of the first %merge from which the type for this
7251 merging function was derived.
7252 * src/symlist.h (symbol_list.merger_declaration_location): New member
7253 storing the location of a rule's %merge, if any.
7254 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7255 declared later): New test to catch the error fixed by the above patch.
7257 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7259 Get action warnings (grammar_rule_check) right even when symbol
7260 declarations appear after the rules. Discussed at
7261 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
7263 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
7264 Don't mistake the type of $$ in a midrule to be that of its parent
7266 * src/reader.c (grammar_current_rule_end): Don't invoke
7267 grammar_rule_check yet since not all symbol declarations may have been
7269 (grammar_midrule_action): Likewise.
7270 Don't record whether the midrule's $$ has been used yet since actions
7271 haven't been translated yet.
7272 Record the midrule's parent rule and its RHS index within the parent
7274 (grammar_current_rule_action_append): Don't translate the action yet
7275 since not all symbol declarations may have been parsed yet and, thus,
7276 warnings about types for $$, $n, @$, and @n can't be reported yet.
7277 (packgram): Translate the action and invoke grammar_rule_check now that
7278 all symbol declarations have been parsed.
7279 * src/scan-code.l (handle_action_dollar): Now that this is invoked
7280 after parsing the entire grammar file, the symbol list here in the case
7281 of a midrule is actually the midrule's empty RHS, so reference its
7282 parent rule's RHS where necessary.
7283 On the other hand, now that you can already know it's a midrule, you
7284 aren't forced to think $$ has the same type as its parent rule's $$.
7285 (handle_action_at): In the case of a midrule, reference the parent rule
7287 * src/symlist.c (symbol_list_new): Initialize new midrule-related
7289 (symbol_list_length): Now that this is invoked after all rules have
7290 been parsed, a NULL symbol (rather than a NULL symbol list node)
7291 terminates a rule. symbol_list_print already does this correctly.
7292 * src/symlist.h (symbol_list.midrule_parent_rule,
7293 symbol_list.midrule_parent_rhs_index): New members so that midrules can
7294 remember their relationships with their parents.
7295 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
7296 fixed by the above patch.
7297 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
7299 (Unused values): ... this old test case and...
7300 (Unused values before symbol declarations): ... this new test case.
7301 This one is the same as `Unused values' except that all symbol
7302 declarations appear after the rules in order to catch the rest of the
7303 errors fixed by the above patch.
7305 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7308 * src/reader.c (current_rule): Declare it static since it's no longer
7309 used outside this file.
7310 (grammar_current_rule_action_append): Remove redundant arguments from
7311 translate_rule_action invocation.
7312 * src/reader.h (current_rule): Remove this unused extern.
7313 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
7314 * src/scan-code.l (translate_rule_action): Likewise.
7316 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
7318 Clean up yesterday's patch.
7319 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
7321 * src/reader.c (grammar_current_rule_action_append): ... here for
7322 consistency with grammar_current_rule_symbol_append.
7323 * tests/regression.at (Braced code in declaration in rules section):
7324 Make yyerror and yylex static as usual.
7326 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
7328 Fix bug that mistakes braced code in a declaration in the rules section
7329 to be a rule action. Mentioned at
7330 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
7331 * src/scan-gram.l: Move midrule action detection from the start of the
7332 scanning of any braced code to...
7333 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
7334 action. For readability, use $2 and @2 rather than the equivalent
7336 * tests/regression.at (Braced code in declaration in rules section):
7337 New test to catch the error fixed by the above patch.
7339 Work on code readability some.
7340 * src/scan-code.l (current_rule): Get rid of this misleading and
7341 redundant declaration: it's actually extern'ed in reader.h.
7342 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
7343 translate_action): Add a rule argument and use it instead of the global
7345 (translate_rule_action): This already receives current_rule through an
7346 argument, so pass it on to translate_action instead of assigning
7347 current_rule to current_rule.
7348 (translate_symbol_action, translate_code): Pass rule = NULL to
7351 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
7353 Rename %before-definitions to %start-header and %after-definitions to
7354 %end-header. Don't use these declarations to separate pre-prologue
7355 blocks from post-prologue blocks. Add new order-independent
7356 declarations %before-header and %after-header as alternatives to the
7357 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
7358 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
7359 * NEWS (2.3+): Update for these changes.
7360 * data/glr.c (b4_before_definitions): Update to...
7361 (b4_start_header): ... this.
7362 (b4_after_definitions): Update to...
7363 (b4_end_header): ... this.
7364 * data/glr.cc: Likewise.
7365 * data/lalr1.cc: Likewise.
7366 * data/yacc.c: Likewise.
7367 * doc/bison.texinfo (The prologue): Update names, and replace remaining
7368 prologue blocks with %*-header declarations.
7369 (Calc++ Parser): Likewise.
7370 (Decl Summary): Update names.
7371 (Table of Symbols): Update description.
7372 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
7373 (PERCENT_END_HEADER): ... this.
7374 (PERCENT_BEFORE_DEFINITIONS): Update to...
7375 (PERCENT_START_HEADER): ... this.
7376 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
7377 (declaration): Update token names and m4 macro names.
7378 When parsing %end-header and %start-header, invoke translate_code
7379 before muscle_code_grow, and no longer set global booleans to remember
7380 whether these declarations have been seen.
7381 Parse new %after-header and %before-header.
7382 * src/reader.c (before_definitions, after_definitions): Remove.
7383 (prologue_augment): Accept a new bool argument to specify whether to
7384 augment the pre-prologue or post-prologue.
7385 * src/reader.h (before_definitions, after_definitions): Remove these
7387 (prologue_augment): Add new bool argument.
7388 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
7389 (PERCENT_END_HEADER): ... this.
7390 (PERCENT_BEFORE_DEFINITIONS): Update to...
7391 (PERCENT_START_HEADER): ... this.
7392 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
7393 * tests/actions.at (Printers and Destructors): Update names.
7395 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
7397 Add comparison operators for C++ location classes. Discussed at
7398 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
7399 * data/c++.m4 (b4_define_location_comparison): New boolean %define
7400 declaration indicating whether filename_type has an operator==. If
7401 filename_type is `std::string', it defaults to `1', `0' otherwise.
7402 * data/location.cc: Iff b4_define_location_comparison is `1', add
7403 operator== and operator!= for class position and for class location.
7406 * src/scan-action.l: Remove unused file.
7407 * src/symtab.c (symbol_printer_set): Use printer_location not
7408 destructor_location.
7409 * src/symtab.h (struct symbol): Replace incorrect source comment for
7411 * tests/input.at (Incompatible Aliases): Update output with correct
7414 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
7416 Don't put the pre-prologue in the header file. For the yacc.c code
7417 file and the glr.c header and code files, move the pre-prologue before
7418 the token definitions. Add new %before-definitions and
7419 %after-definitions to declare code that will go in both the header file
7420 and code file. Discussed at
7421 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
7422 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
7424 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
7425 * NEWS (2.3+): Describe these changes.
7426 * data/glr.c (b4_pre_prologue): Move from within to before...
7427 (b4_shared_declarations): ... this.
7428 Add new b4_before_definitions before b4_token_enums.
7429 Add new b4_after_definitions at the end.
7430 * data/glr.cc (b4_pre_prologue): Replace with...
7431 (b4_before_definitions): ... this in the header file.
7432 (b4_after_definitions): New near the end of the header file.
7433 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
7434 code file right before including the header file.
7435 (b4_before_definitions): New in the previous position of
7436 b4_pre_prologue in the header file.
7437 (b4_after_definitions): New near the end of the header file.
7438 * data/yacc.c: Clean up some m4 quoting especially in the header file.
7439 (b4_token_enums_defines): In the code file, move to right before
7440 YYSTYPE for consistency with the header file.
7441 (b4_before_definitions): New right before b4_token_enums_defines in
7442 both the header and code file.
7443 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
7444 header and code file.
7445 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
7446 of prologues for %union dependencies.
7447 (Decl Summary): In %defines description, mention the effect of
7448 %before-definitions and %after-definitions on the header file.
7449 (Calc++ Parser): Forward declare driver in a %before-definitions rather
7450 than in the pre-prologue so that make check succeeds.
7451 (Table of Symbols): Add entries for %before-definitions and
7453 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
7454 %before-definitions.
7455 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
7456 (declaration): Parse those declarations and append to
7457 b4_before_definitions and b4_after_definitions, respectively.
7458 * src/reader.c (before_definitions, after_definitions): New bools to
7459 track whether those declarations have been seen.
7460 (prologue_augment): Add to the post-prologue if %union,
7461 %before-definitions, or %after-definitions has been seen.
7462 * src/reader.h (before_definitions, after_definitions): New extern's.
7463 * src/scan-gram.l: Scan the new declarations.
7464 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
7465 prologue block in a %before-definitions or a %after-definitions based
7466 on whether the %union is declared.
7467 * tests/regression.at (Early token definitions with --yacc, Early token
7468 definitions without --yacc): Move tests for token definitions into the
7469 post-prologue since token names are no longer defined in the
7472 2006-06-20 Akim Demaille <akim@epita.fr>
7474 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
7475 (symbol_get): Use it.
7476 * src/parse-gram.y: Use it.
7478 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
7480 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
7481 build succeeds when configured with --enable-gcc-warnings.
7483 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7485 * src/parse-gram.y (char_name): New function.
7486 (CHAR, STRING, string_content): For %printer, properly escape.
7487 (ID): Prefer fputs to fprintf.
7488 (id): Reindent to be consistent with other rules.
7489 Properly quote char.
7491 The Translation Project changed its way of publishing translations
7492 to maintainers. I haven't received any responses to my request
7493 for supporting the old way, or for documenting the new way. I
7494 have modified 'bootstrap' to use screen scraping
7495 (in this case, HTML scraping). This is unreliable and inelegant,
7496 but I don't see any better way. Yuck.
7497 * bootstrap (TP_URL, WGET_COMMAND): New vars.
7498 (get_translations): New function, which uses HTML scraping to
7499 deduce locations of latest translations.
7500 Use this function to grab both bison and bison-runtime .po files.
7501 Don't bother priming the pump for the runtime-po domain any more,
7502 as it's now translated better than bison is.
7504 2006-06-19 Akim Demaille <akim@epita.fr>
7506 * src/scan-gram.l: No longer "parse" things after `%union' until
7507 `{'. Rather, return a single "%union" token.
7508 No longer make symbols: return strings, and leave the conversion
7509 to symbols to the parser.
7510 (SC_PRE_CODE, token_type): Remove.
7511 * src/parse-gram.y (%union): New field `character'.
7514 (ID, ID_COLON): Now that the scanner no longer makes them
7515 identifiers, adjust all uses to invoke symbol_get.
7516 (id_colon): New, wraps the conversion from string to symbol.
7517 (%union): Accept a possible union_name.
7518 (symbol): Now can be a char.
7519 * data/c.m4 (b4_union_name): Leave a default value.
7520 * data/glr.c, data/yacc.c: Use it.
7522 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
7524 For associating token numbers with token names for "yacc.c", don't use
7525 #define statements unless `--yacc' is specified; always use enum
7526 yytokentype. Most important discussions start at:
7527 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
7528 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
7530 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
7531 * NEWS (2.3+): Mention.
7532 * data/c.m4 (b4_yacc_if): New.
7533 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
7535 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
7536 on token name definitions.
7537 * src/getargs.c (usage): Capitalize `Yacc' in English.
7538 * src/output.c (prepare): Define b4_yacc_flag.
7539 * tests/regression.at (Early token definitions): Test that tokens names
7540 are defined before the pre-prologue not just before the post-prologue.
7541 Remove this test case and copy to...
7542 (Early token definitions with --yacc): ... this to test #define's.
7543 (Early token definitions without --yacc): ... and this to test enums.
7545 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
7547 * NEWS: Reword the post-2.3 change to not be so optimistic about
7548 removing the old "look-ahead" spelling.
7549 Update previous look-ahead/lookahead change reports.
7550 * REFERENCES: look-ahead -> lookahead (since that's
7551 what he actually wrote).
7552 * doc/refcard.tex: look ahead -> lookahead,
7553 look-ahead -> lookahead
7555 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
7557 For consistency, use `lookahead' instead of `look-ahead' or
7558 `look_ahead'. Discussed starting at

7634 * TODO: Add request from Nelson H. F. Beebe to be able to install
7635 Bison without installing the yacc script.
7637 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>

7649 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
7651 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
7652 loc argument as it shadows a global.
7653 * src/scan-gram.l: Remove stray comma that prevents boundary_set
7656 * src/.cvsignore: Add scan-code.c.
7658 2006-06-07 Akim Demaille <akim@epita.fr>
7660 * src/scan-gram.l: Move the "add a trailing ; to actions" code
7662 * src/scan-code.l: here.
7663 * tests/input.at (Torturing the Scanner): Fix another location
7666 2006-06-07 Akim Demaille <akim@epita.fr>
7668 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
7670 2006-06-06 Akim Demaille <akim@epita.fr>
7672 Extract the parsing of user actions from the grammar scanner.
7673 As a consequence, the relation between the grammar scanner and
7674 parser is much simpler. We can also split "composite tokens" back
7676 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
7677 * src/scan-gram.l (add_column_width, adjust_location): Move to and
7679 * src/location.h, src/location.c (add_column_width)
7680 (location_compute): these.
7681 Fix the column count: the initial column is 0.
7682 (location_print): Be robust to ending column being 0.
7683 * src/location.h (boundary_set): New.
7684 * src/main.c: Adjust to scanner_free being renamed as
7686 * src/output.c: Include scan-code.h.
7687 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
7689 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
7690 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
7691 which is now, again, a separate token.
7692 Adjust all dependencies.
7693 Whereever actions with $ and @ are used, use translate_code.
7694 (action): Remove this nonterminal which is now useless.
7695 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
7696 (grammar_current_rule_action_append): Use translate_code.
7697 (packgram): Bound check ruleno, itemno, and rule_length.
7698 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
7699 (last_string, last_braced_code_loc, max_left_semantic_context)
7700 (scanner_initialize, scanner_free, scanner_last_string_free)
7701 (gram_out, gram_lineno, YY_DECL_): Move to...
7702 * src/scan-gram.h: this new file.
7703 (YY_DECL): Rename as...
7705 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
7706 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7707 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7708 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7709 Move these declarations, and...
7710 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
7712 * src/flex-scanner.h: this new file.
7713 * src/scan-gram.l (rule_length, rule_length_overflow)
7714 (increment_rule_length): Remove.
7715 (last_braced_code_loc): Rename as...
7716 (gram_last_braced_code_loc): this.
7717 Adjust to the changes of the parser.
7718 Move all the handling of $ and @ into...
7719 * src/scan-code.l: here.
7720 * src/scan-gram.l (handle_dollar, handle_at): Remove.
7721 (handle_action_dollar, handle_action_at): Move to...
7722 * src/scan-code.l: here.
7723 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
7724 scan-code.h, scan-code-c.c, scan-gram.h.
7725 (EXTRA_bison_SOURCES): Add scan-code.l.
7726 (BUILT_SOURCES): Add scan-code.c.
7727 (yacc): Be robust to white spaces.
7729 * tests/conflicts.at, tests/input.at, tests/reduce.at,
7730 * tests/regression.at: Adjust the column numbers.
7731 * tests/regression.at: Adjust the error message.
7733 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7735 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7736 Use Akim's wording from
7737 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
7739 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7741 Between Bison releases, manually append `+' to the previous Bison
7742 release number, and use that as a signal to automatically print the
7743 ChangeLog's CVS Id keyword from --version. Discussed starting at
7744 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
7745 * ChangeLog: Add Id header.
7746 * configure.ac (AC_INIT): Append `+' to `2.3'.
7747 * src/.cvsignore: Add revision.c.
7748 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
7749 (BUILT_SOURCES): Add revision.c.
7750 (revision.c): New target rule. This file defines a new global variable
7751 named revision. It initializes it with either the Id from ChangeLog
7752 or, if VERSION doesn't contain `+', with the empty string.
7753 * src/getargs.c (version): Print the value of revision.
7754 * src/revision.h: Extern revision.
7756 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7758 * NEWS: Version 2.3.
7759 * configure.ac (AC_INIT): Likewise.
7761 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7763 * data/glr.c (YYRECOVERING): Define to be a function-like macro
7764 with no arguments, not as an object-like macro. This is for
7765 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
7766 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
7767 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
7770 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
7772 * src/getargs.c (usage): Back out yesterday's modification of the
7773 --help output so that we don't have to wait for translation before
7776 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7778 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
7779 Problem reported by Akim Demaille.
7781 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
7783 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7785 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7787 * data/yacc.c (yy_reduce_print): Omit trailing white space in
7788 generated source code. Problem reported by Frans Englich in
7789 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7791 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7793 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7794 shell, not within 'make', so that 'make' by an ordinary builder
7795 (using GNU make) does not worry about configuring gzip. This also
7796 works around a bug reported independently by Keith Thompson and by
7797 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7798 stderr rather than stdout, messing up the build logs.
7800 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7802 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7803 to make sure that YYID will never be unused. This fixes a 'make
7804 maintainer-check' failure caused by the recent changes to the 'Trivial
7805 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7807 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7809 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7811 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7812 state before an empty RHS is always resolved here. Only the location
7813 of that state is guaranteed to be resolved, and that's enough. This
7814 fixes the remaining bug reported by Derek M. Jones in
7815 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7816 * tests/glr-regression.at (Uninitialized location when reporting
7817 ambiguity): Test the above case.
7818 Also, the embedded comments in this test case claim it checks the case
7819 of an empty RHS that has inherited the initial location. However, the
7820 corresponding LHS was already resolved, so yyresolveLocations didn't
7821 actually have reason to modify it. Fix this by forcing
7822 nondeterministic operation at the beginning of the parse.
7824 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7826 * data/c.m4 (b4_yy_symbol_print_generate):
7827 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7828 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7829 of the bugs reported today by Derek M Jones in
7830 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7831 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7832 defined to be a type name without parens or brackets.
7833 (Location Type): Similarly for YYLTYPE.
7834 * tests/regression.at (Trivial grammars): Put in a test for this
7835 bug that will be caught by 'make maintainer-check' (though not,
7836 alas, by 'make check' unless your compiler is picky).
7838 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
7840 * NEWS: Version 2.2.
7841 * configure.ac (AC_INIT): Likewise.
7843 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
7845 * data/glr.c (yyreportTree): Make room in yystates for the state
7846 preceding the RHS. This fixes the segmentation fault reported by Derek
7848 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7849 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7850 to the user. Reported for yyreportTree by Derek M. Jones later in the
7852 * THANKS: Add Derek M. Jones.
7853 Update my email address.
7854 Fix typo in Steve Murphy's name.
7856 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7858 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7859 checking against YYLAST that caused the parser to miss a potential
7860 alternative in its diagnostic.
7861 Problem reported by Maria Jose Moron Fernandez in
7862 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
7863 * data/lalr1.cc (yysyntax_error_): Likewise.
7864 * data/yacc.c (yysyntax_error): Likewise.
7865 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7866 tokens, in case we run into an older C compiler.
7867 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7868 Use them to check for the off-by-one error fixed above.
7870 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7871 YYSIZE_T, not size_t.
7872 * tests/regression.at (Trivial grammars): New test, to catch
7873 the error fixed by the above patch.
7875 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7877 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7879 Reported by Steve Murphy.
7881 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7883 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7884 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7886 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7888 Implement --trace=m4.
7889 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7890 * src/output.c (output_skeleton): When set, pass -dV to m4.
7892 Factor the handling of flags in m4.
7893 * src/output.c (prepare): Rename the muscle names debug, defines,
7894 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7895 * data/c.m4: Adjust.
7896 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7897 Use b4_define_flag_if to define other b4_FLAG_if macros.
7898 (b4_location_if): As a consequence, rename as...
7899 (b4_locations_if): this, for consistency.
7900 Adjust all the skeletons.
7902 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7904 * etc/bench.pm: Shorten bench names.
7906 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7908 * src/output.h, src/output.c (error_verbose): Move to...
7909 * src/getargs.h, src/getargs.c: here.
7911 Adjust dependencies.
7913 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7915 * data/c.m4 (b4_copyright): Put the special exception for Bison
7916 skeletons here, so we don't have to put it in each skeleton. All
7917 uses changed. Suggested by Akim Demaille. Also, wrap the
7918 copyright notice, in case it is longer than 80 columns. Replace
7919 comma by newline after title.
7921 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7923 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7924 incompatibility, not a bug. Mention that it wasn't fixed as of
7927 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7929 * examples/extexi: Enforce the precedence of concatenation over
7931 Reported by Tommy Nordgren.
7933 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7935 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7936 with the member "token".
7937 Reported by Martin Nylin.
7939 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
7941 * data/glr.c: Switch to Bison 2.2 special-exception language in
7942 the copyright notice. Use more-regular format for titles and
7944 * data/glr.cc: Likewise.
7945 * data/location.cc: Likewise.
7946 * data/yacc.cc: Likewise.
7947 * doc/bison.texinfo (Conditions): Document this.
7948 * NEWS: likewise. Upgrade version to 2.2.
7950 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
7952 * data/glr.cc: Remove dead code.
7954 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
7956 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
7957 that variable and the line breaks the bootstrap. Problem reported
7958 by Juan M. Guerrero.
7960 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
7962 * doc/bison.texinfo (Multiple start-symbols): New.
7964 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
7966 * etc/README, etc/bench.pl: New.
7968 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
7970 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
7972 Reported by Mickael Labau.
7973 * tests/input.at (Torturing the Scanner): Test it.
7975 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
7977 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
7978 Problem reported by Bob Rossi.
7980 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
7982 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
7983 and didn't really work.
7984 For the index, use @ifnotinfo, not @iftex.
7985 Minor cleanups of spacing and terminology.
7987 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7989 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
7990 of AT_NAME_PREFIX when %name-prefix is not used.
7992 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7994 Apply --prefix to C++ skeletons too: they change the namespace.
7995 The test suite already exercize these cases.
7996 * data/c++.m4 (b4_namespace): New.
7997 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
7998 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
7999 * data/yacc.c, data/glr.c: Remove a useless `[]'.
8000 * doc/bison.texinfo: Document it.
8001 (Option Cross Key): Use @multitable in all formats. It looks
8002 nicer, even in TeX outputs.
8003 (Rules): Use the same code whatever the output type is.
8004 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
8005 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
8006 * tests/calc.at: Use it, instead of hard coding `yy'.
8008 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
8010 * TODO: Remove dead items.
8012 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
8014 * doc/FAQ: Remove, merged into...
8015 * doc/bison.texinfo (FAQ): this.
8016 * doc/Makefile.am (EXTRA_DIST): Adjust.
8018 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
8020 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
8022 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
8023 * doc/bison.texinfo (Calc++ Scanner): Use it.
8025 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
8027 Fix two nits reported by twlevo, plus one more that I discovered.
8029 * src/assoc.h (assoc_to_string): Give a name to the arg, as
8030 this is the usual Bison style.
8031 * src/location.h (location_print): Likewise.
8033 * src/reader.h (token_name): Likewise.
8035 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
8037 Fix some nits reported by twlevo.
8038 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
8039 and "POSIX". Use more-modern syntax for URLs. Mention C++
8040 and ask for Java. Don't hardwire OS version numbers. Add
8042 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
8043 * src/conflicts.c (solved_conflicts_obstack): Now static.
8045 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
8047 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
8048 page. Say "you can use it" not "you may use it" as on the web page;
8049 we're describing capabilities not granting permission.
8051 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
8053 * data/glr.c (yyresolveLocations): Rename local variables to avoid
8054 shadowing warnings. Use usual patter for iterating through RHS.
8055 * tests/glr-regression.at
8056 (Uninitialized location when reporting ambiguity):
8057 Modify yylex so that it uses its argument, rather than trying
8058 to rely on ARGSUSED (which doesn't work for gcc with warnings).
8059 const char -> char const.
8061 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
8062 Don't use tabs inside commands; it messes up 'ps'.
8063 Problem reported by twlevo.
8065 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
8067 * tests/glr-regression.at (Uninitialized location when reporting
8068 ambiguity): New test case.
8069 * data/glr.c (yyresolveLocations): New function, which uses
8071 (yyresolveValue): Invoke yyresolveLocations before reporting an
8073 * doc/bison.texinfo (Default Action for Locations): Note
8074 YYLLOC_DEFAULT's usage for ambiguity locations.
8075 (GLR Semantic Actions): Cross-reference those notes.
8077 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
8079 * tests/glr-regression.at (Leaked semantic values when reporting
8080 ambiguity): Remove unnecessary union and type declarations.
8081 (Leaked lookahead after nondeterministic parse syntax error): New test
8083 * data/glr.c (yyparse): Check for zero stacks remaining before
8084 attempting to shift the lookahead so that you don't lose it.
8086 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
8088 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
8089 * tests/glr-regression.at (Leaked semantic values when reporting
8090 ambiguity): New test case.
8091 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
8092 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
8093 now unnecessary yystackp parameter.
8094 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
8095 destructors can be called.
8097 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
8098 in existing testcases.
8100 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
8102 Don't leak semantic values for parent RHS when a user action cuts the
8103 parser, and clean up related code a bit.
8104 * tests/glr-regression.at (Leaked merged semantic value if user action
8105 cuts parse): Rename to...
8106 (Leaked semantic values if user action cuts parse): ... this. Add check
8107 for leaked parent RHS values.
8108 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
8109 between an unresolved state (non-empty chain of semantic options) and
8110 an incomplete one (signaled by an empty chain).
8111 (yyresolveStates): Document the interface. Move all manipulation of a
8112 successfully or unsuccessfully resolved yyGLRState to...
8113 (yyresolveValue): ... here so that yyresolveValue always leaves a
8114 yyGLRState with consistent data and thus is easier to understand.
8115 Remove the yyvalp and yylocp parameters since they are always just
8116 taken from the yys parameter. When reporting a discarded merged value
8117 in debugging output, note that it is incompletely merged. Document the
8119 (yyresolveAction): If resolving any of the RHS states fails, destroy
8120 them all rather than leaking them. Thus, as long as user actions are

8188 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
8189 nodist_PROGRAMS, since we don't need to actually compile the

8241 During deterministic GLR operation, user actions should be able to
8242 influence the parse by changing yychar. To make this easier to fix and
8243 to make glr.c easier to evolve in general, don't maintain yytoken in
8244 parallel with yychar; just compute yytoken when needed.

8271 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
8272 got from <http://bro-ids.org/download.html>. The bug is that
8273 when two actions appeared in succession, the second one was
8274 scanned before the first one was added to the grammar rule
8275 as a midrule action. Bison then output the incorrect warning
8276 "parse.y:905.17-906.36: warning: unused value: $3".

8538 in the yychar entry.
8539 In the yychar entry, remove mention of the local yychar case (pure
8540 parser) since this is irrelevant information when writing semantic
8541 actions and since it's already discussed in `Table of Symbols' where

8584 titles for consistency.
8585 (Leaked merged semantic value if user action cuts parse): In order to
8586 suppress lint warnings, use arguments in merge function, and assign

8600 * tests/glr-regression.at: For consistency with my newer test cases,
8603 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
8605 * data/glr.c (yyresolveValue): When merging semantic options, if at
8606 least one user action succeeds but a later one cuts the parse, then
8607 destroy the semantic value before returning rather than leaking it.
8608 (yyresolveStates): If a user action cuts the parse and thus
8609 yyresolveValue fails, ignore the (unset) semantic value rather than
8610 corrupting the yyGLRState, and empty the semantic options list since
8611 the user actions should have called all necessary destructors.
8612 Simplify code with YYCHK.
8613 * tests/glr-regression.at (Corrupted semantic options if user action
8614 cuts parse): New test case.
8615 (Undesirable destructors if user action cuts parse): New test case.

8699 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF

8738 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):

8740 Use increment_rule_length rather than incrementing it by hand.
8741 (adjust_location, handle_syncline): Diagnose overflow.

8743 Fix bug with monstrosities like $-2147483648.

8838 for semantic values was leaked instead.
8840 2005-12-21 Joel E. Denny <address@hidden>
8842 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.

8883 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

8913 sed out the final state number.
8915 Work around portability problem on Solaris 10: flex-generated
8916 files include <stdio.h> before <config.h>, which messes up
8917 because the latter defines __EXTENSIONS__. Address the problem
8918 by creating two new little files that include <config.h> first,
8919 then include the flex-generated files. Rewrite everyone else
8920 to include <config.h> first, as well.
8921 * lib/timevar.c: Always include "config.h".

8997 it's no longer just a file.
8998 * data/glr.c: Grant a special exception for C GLR parsers, that
8999 reads like the already-existing exception for C LALR(1) parsers.

9157 * bootstrap (cleanup_gnulib): New function. Use it to clean up
9158 gnulib when interrupted. This fixes some race conditions and
9159 works around some portability problems (one noted by Paul
9162 2005-10-22 Akim <akim@epita.fr>

9258 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
9260 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
9262 Undo the parts of the unlocked-I/O change that substituted
9263 putc or puts for printf. This might hurt performance a bit,
9264 but some people prefer the printf style.
9265 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
9266 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

9287 unused-variable warnings.
9289 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

9293 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
9295 Use unlocked I/O for a minor performance improvement on hosts like
9296 GNU/Linux and Solaris that support unlocked I/O. The basic idea
9297 is to use the gnlib unlocked-io module, and to prefer putc and
9298 puts to printf when either will work (since the latter doesn't
9299 come in an unlocked flavor).
9300 * bootstrap (gnulib_modules): Add unlocked-io.
9301 * data/c.m4 (yysymprint): Prefer puts and putc to printf.

9319 * src/system.h: Include unlocked-io.h rather than stdio.h.
9321 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

9371 to allow support for non-posix systems. This is a no-op function
9374 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
9375 handle the lack of pipe/fork functionality on non-posix systems.

9414 (parser::semantic_value): Now a full definition instead of an
9415 indirection to YYSTYPE.

9459 local variables whose names begin with 'yy'.
9460 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
9461 Trivial changes from Joel E. Denny.
9463 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
9465 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
9466 don't use alloca any more.
9468 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
9469 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
9470 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

9481 This works a bit better with glibc, if user code has already included
9483 * doc/bison.texinfo (Bison Parser): Document that users can't
9484 arbitrarily use malloc and free for other purposes. Document

9503 Instead, reallocate buffers twice as big each time, so that
9504 we waste at most half the allocated memory. Start with a small
9505 (128-byte) buffer that will suffice in most cases anyway.
9506 Use yysyntax_error to do most of the work.
9508 * doc/bison.texinfo (Error Reporting, Table of Symbols):
9509 yynerrs is the number of errors reported, not the number of

9516 Don't start user-code symbols with "yy", to avoid name space problems.
9518 2005-09-19 Akim Demaille <akim@epita.fr>
9520 Remove the traits, failed experiment.
9521 It never proved useful, and anyway because of the current
9522 definition, it was not possible to have several specialization of
9523 this traits, making it useless.
9524 * data/lalr1.cc (yy:traits): Remove.
9525 Inline its definitions in the parser class.
9527 2005-09-19 Akim Demaille <akim@epita.fr>

9547 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
9549 * src/output.c (prepare): Likewise.
9550 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
9551 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
9552 is not defined. This is an awful hack, but it's enough for now.
9553 All callers changed.
9554 * tests/glr-regression-at (make_value): Args are const pointers now,
9555 to avoid GCC warning.
9556 (Duplicated user destructor for lookahead): New test. Currently
9557 skipped. It fails on my host but I'm not sure it'll always fail.
9559 2005-09-16 Akim Demaille <akim@epita.fr>
9561 * src/symtab.h (struct symbol): Declare the printer and destructor
9562 as const, to avoid accidental calls to free.
9563 (symbol_destructor_set, symbol_printer_set): Adjust.
9564 * src/symtab.c: Adjust.
9566 2005-09-16 Akim Demaille <akim@epita.fr>
9568 * data/c.m4 (b4_token_enums): New.
9569 (b4_token_defines): Rename as...
9570 (b4_token_enums_defines): this.
9571 (b4_token_defines): New, output only the #defines.
9572 * data/yacc.c, data/glr.c: Adjust.
9573 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
9574 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
9577 2005-09-16 Akim Demaille <akim@epita.fr>
9579 * data/lalr1.cc (yylex_): Remove, inline its code.
9580 (yyreport_syntax_error_): Remove, replaced by...
9581 (yysyntax_error_): this which returns a string and leaves to the
9582 caller the call to the users' error function.
9583 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
9584 Move from members of the parser object...
9585 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
9586 to local variables of the parse function.
9588 2005-09-16 Akim Demaille <akim@epita.fr>
9590 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
9591 since it's in Bison's name space.
9593 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
9595 * data/glr.c (yyresolveValue): Add default case to pacify
9596 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
9598 * NEWS: Document when yyparse started to return 2.
9599 * doc/bison.texinfo (Parser Function): Document when yyparse
9602 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
9603 (b4_filename_type): Renamed back from b4_file_name_type. All uses
9605 (class position): file_name -> filename (reverting). All uses changed.
9607 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
9609 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
9610 do anything if $@ exists. This reverts part of the 2005-07-07
9613 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
9615 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
9616 contains obsolete information and isn't worth distributing as a
9617 separate file anyway.
9618 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
9619 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
9620 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
9621 (yyparse): Abort if user code uses longjmp to throw an unexpected
9624 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
9626 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
9627 Suggested by twlevo@xs4all.nl.
9629 * data/glr.c (YYCHK1): Do not assume YYE is in range.
9630 This avoids a diagnostic from gcc -Wswitch-enum.
9631 Problem reported by twlevo@xs4all.nl.
9633 * doc/bison.texinfo: Don't use "filename", as per GNU coding
9634 standards. Use "file name" or "file" or "name", depending on
9636 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
9637 not to hack/foo.tab.c.
9638 (Calc++ Top Level): 2nd arg of main is not const.
9639 * data/glr.c: b4_filename -> b4_file_name.
9640 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

9648 * src/files.c (file_name_split): Renamed from filename_split.
9649 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.

9657 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
9659 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
9662 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
9664 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
9665 All uses changed. Invoke user destructor after an error during a
9666 split parse (trivial change from Joel E. Denny).
9668 * tests/glr-regression.at
9669 (User destructor after an error during a split parse): New test case.
9670 Problem reported by Joel E. Denny in:
9671 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
9673 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9675 * README-cvs: Give URLs for recommended tools.
9676 Mention Gzip version problem, and bootstrapping issues.
9677 Remove troubleshooting section, as it's somewhat obsolete.
9679 * bootstrap (no_cache): New var, to accommodate different wget
9680 variants. Use it instead of '-C off'. Problem reported by
9683 * data/glr.c (yydestroyStackItem): New function.
9684 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
9685 debugging information. Problem reported by Joel E. Denny.
9687 2005-08-25 Akim Demaille <akim@epita.fr>
9689 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
9691 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

9695 * tests/glr-regression.at
9696 (User destructor for unresolved GLR semantic value): New test case.
9697 Problem reported by Joel E. Denny in:
9698 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
9700 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
9702 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
9704 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
9705 lib-prefix.m4, po.m4.
9707 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
9708 in yydestruct diagnostic, since it might not be an error.
9709 Problem reported by Joel Denny near end of
9710 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9711 * data/lalr1.cc (yyerturn): Likewise.
9712 * data/yacc.c (yyreturn): Likewise.
9713 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
9715 * src/files.c: Remove obsolete FIXME comment.
9717 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
9718 with the other templates, and to fix bogus run-on messages such
9719 as the one reported at the end of
9720 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9721 All callers changed to avoid the newline.
9722 (yyprocessOneStack): Output two lines rather than one, to accommodate
9723 the above change. This changes the debug output format slightly.
9725 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
9726 reported by Joel E. Denny in
9727 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
9729 * tests/glr-regression.at (Duplicate representation of merged trees):
9730 New test, from Joel E. Denny in:
9731 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
9732 * THANKS: Add Joel E. Denny.
9734 * configure.ac (AC_INIT): Bump to 2.0c.
9736 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
9738 * NEWS: Version 2.0b.
9740 * Makefile.am (SUBDIRS): Put examples before tests, so that
9741 "make check" doesn't finish with "All 1 tests passed".
9743 * tests/regression.at (Token definitions): Don't rely on
9744 AT_PARSER_CHECK for data that contains backslashes. It currently
9745 uses 'echo', and 'echo' isn't portable if its argument contains
9746 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9747 that the byte '\0xff' is not printable in the C locale; it is,
9748 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9749 not printable, so use '\0x81' to test.
9751 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
9752 version of GCC, since the macro is used with non-GCC compilers.
9754 Fix core dump reported by Pablo De Napoli in
9755 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
9756 * tests/regression.at (Invalid inputs with {}): New test.
9757 * src/parse-gram.y (token_name): Translate type before using
9760 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
9761 the user's name space. All uses changed to __attribute__
9763 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
9764 Add __attribute__ ((__noreturn__)).
9766 * etc/clcommit: Remove. We weren't using it, and it failed
9767 "make maintainer-distcheck".
9768 * Makefile.maint: Merge from coreutils.
9769 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
9770 (syntax-check-rules): Change list of rules as described below.
9771 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
9772 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
9773 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
9774 (sc_trailing_space): New rules.
9775 (sc_xalloc_h_in_src): Remove.
9776 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
9777 (sc_space_tab, sc_error_exit_success, sc_changelog):
9778 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
9779 (makefile-check, po-check, author_mark_check):
9780 (makefile_path_separator_check, copyright-check):
9781 Use grep -n, to make it easier to find violations.
9782 Use CVS_LIST and CVS_LIST_EXCEPT.
9783 (header_regexp, h_re): Remove.
9785 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
9786 (my-distcheck): Use more-modern GCC flags.
9787 (signatures, %.asc): Remove.
9788 (rel-files, announcement): Remove signatures.
9789 Restore old updating code, even though we don't use it, so
9790 that we're the same as coreutils.
9791 (alpha, beta, major): Depend on news-date-check.
9792 Make the upload commands.
9794 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
9795 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
9796 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
9797 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
9798 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
9799 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
9800 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
9801 * tests/sets.at: Likewise.
9803 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9804 we comment out the Autoconf version number.
9805 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9806 it's error-prone and "make maintainer-distcheck" rejects it.
9808 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9809 Indent calls to "error" to pacify "make maintainer-distcheck",
9810 when the calls are not intended to be translated.
9811 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9813 * src/Makefile.am (DEFS): Use +=, to pacify
9814 "make maintainer-distcheck".
9815 (bison_SOURCES): Add scan-skel.h.
9816 (sc_tight_scope): New rule, from coreutils.
9818 * src/files.c (src_extension, header_extension):
9819 Now static, not extern.
9820 * src/getargs.c (short_options): Likewise.
9821 * src/muscle_tab.c (muscle_table): Likewise.
9822 * src/parse-gram.y (current_class, current_type, current_prec):
9824 * src/reader.c (grammar_end, previous_rule_end): Likewise.
9825 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9826 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9827 void, to avoid warning when NLS is disabled.
9828 * src/output.c: Include scan-skel.h.
9829 (scan_skel): Remove decl, since scan-skel.h does this.
9831 Indent calls to "error" to pacify "make maintainer-distcheck".
9832 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9833 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9834 "make maintainer-distcheck".
9835 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
9836 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
9837 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
9838 (skel_lex_destroy, scan_skel): Move these decls to...
9839 * src/scan-skel.h: New file.
9840 * src/uniqstr.c (uniqstr_assert):
9841 Indent calls to "error" to pacify "make maintainer-distcheck".
9843 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9846 * tests/torture.at: Revamp to avoid misuse of atoi that
9847 "make maintainer-distcheck" complained about.
9849 * examples/extexi (message): Don't print a message more than once,
9850 and omit line-number decoration that makes Emacs compile think
9851 that informative messages are worth worrying about.
9853 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9855 * configure.ac: Update version number.
9857 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9859 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9860 autogenerated by the maintainer.
9861 * examples/calc++/.cvsignore: Add *.yy.
9863 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9864 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9865 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9867 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9869 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9870 from maintainer-distcheck about casting the argument of 'free'.
9872 * NEWS: Mention recent yytname changes.
9873 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9875 * bootstrap: For translations that have not yet been upgraded to
9876 the new runtime-po domain, prime the pump by extracting the
9877 relevant strings from the obsolete translations. This code can be
9878 removed once the bison-runtime domain has been translated by each
9881 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9882 now that token names are already quoted.
9884 Fix problem reported by Anthony Heading.
9885 * data/glr.c (YYTOKEN_TABLE): New macro.
9886 (yytname): Define if YYTOKEN_TABLE.
9887 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
9888 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
9889 (YYERROR_VERBOSE): Define the same way the other skeletons do.
9890 * src/output.c (prepare_symbols): Output token_table_flag.
9892 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9894 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9895 again if the first call fails.
9897 * data/glr.c (yytnamerr): New function.
9898 (yyreportSyntaxError): Use it to dequote most string literals.
9899 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9900 with other skeletons. All uses changed.
9901 (yytnameerr_): New function.
9902 (yyreport_syntax_error): Use it to dequote most string literals.
9903 * data/yacc.c (yytnamerr): New function.
9904 (yyerrlab): Use it to decode most string literals.
9905 * doc/bison.texinfo (Decl Summary, Calling Convention):
9906 Clarify quoting convention of yytname.
9907 * src/output.c (prepare_symbols): Quote all names. This undoes
9908 the 2005-04-17 change, which is now accomplished (mostly) via
9909 changes in the parsers as described above.
9910 * tests/regression.at (Token definitions, Web2c Actions):
9911 Undo most 2005-04-17 change here, too.
9913 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9915 Fix more problems reported by twlevo@xs4all.nl.
9916 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9917 remove trailing spaces. This loses the exit status of ./types,
9918 and isn't needed since ./types shouldn't be emitting trailing
9920 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9921 as the stack isn't valid in that case.
9923 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9924 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9925 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9926 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9928 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
9929 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9930 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9933 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9934 overly-picky compilers that reject 'char *foo = "bar";'.
9936 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9937 to FILE * parameter, not to stderr. This fixes a typo introduced
9938 in the 2005-07-12 change.
9940 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
9941 warnings from GCC 4.
9943 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
9944 (yyglrShiftDefer, yysplitStack):
9945 Remove unused parameters b4_pure_formals. All uses changed.
9946 (yyglrShift): Remove unused parameters b4_user_formals.
9948 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
9950 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
9952 Destructor cleanups and regularization among the three skeletons.
9953 * NEWS: Document the behavior changes.
9954 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9955 stack before failing, as the cleanup code will do it for us now.
9956 * data/lalr1.cc (yyerrlab): Likewise.
9957 * data/glr.c (yyparse): Pop everything off the stack before
9958 freeing it, so that destructors get called properly.
9959 * data/lalr1.cc (yyreturn): Likewise.
9960 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9961 This is more consistent.
9962 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9963 why destructors might be called. 1.875 -> 2.1.
9964 (Destructor Decl, Decl Summary, Table of Symbols):
9965 Some English-language cleanups for %destructor.
9966 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9967 Add output line for destructor of start symbol.
9968 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
9969 because of that same extra output line.
9971 * NEWS: Document minor wording changes in diagnostics of
9972 Bison-generated parsers.
9973 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
9974 Remove unused formals. All uses changed.
9975 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9976 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9977 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9978 Rename yyoverflowab to yyexhaustedlab.
9979 When memory exhaustion occurs during syntax-error reporting,
9980 report it separately rather than in a single diagnostic; this
9982 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
9983 (Memory Exhausted): Renamed from Parser Stack Overflow.
9984 Revamp wording slightly to prefer "memory exhaustion".
9985 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
9987 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
9989 Add i18n support to the GLR skeleton. Partially fix the C++
9990 skeleton; a C++ expert needs to finish this. Remove debugging
9991 msgids; there's little point to having them translated, since they
9992 can be understood only by someone who can read the
9993 (English-language) source code.
9995 Generate runtime-po/bison-runtime.pot automatically, so that we
9996 don't have to worry about garbage getting in that file. We'll
9997 make sure after the next official release that old msgids don't
9999 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
10001 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10002 Now auto-generated.
10003 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10004 Fix typos in explanations of the runtime file.
10005 * bootstrap: Change gettext keyword from YYI18N to YY_.
10006 Use standard Makefile.in.in in runtime-po, since we'll arrange
10007 for backward-compatible bison-runtime.po files in a different way.
10008 * data/glr.c (YY_): New macro, from yacc.c.
10009 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10010 Translate messages intended for users.
10011 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10012 the wording in the other skeletons. We don't know that the memory
10014 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10015 Use same method that yacc.c uses.
10016 Don't translate debugging messages.
10017 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10018 it doesn't work (yet), and requires C++ expertise to fix.
10019 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10020 Move defn to a more logical place, to be consistent with other
10022 Don't translate debugging messages.
10023 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10024 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10025 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10026 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
10028 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
10029 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
10031 * tests/glr-regression.at (Badly Collapsed GLR States):
10033 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
10034 yylex should return 0 at EOF rather than aborting.
10036 Improve tests for stack overflow in GLR parser.
10037 Problem reported by twlevo@xs4all.nl.
10038 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
10040 (yyStackOverflow): Just longjmp, but with value 2 so that caller
10041 can handle the problem.
10042 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
10043 (yyparse): New local variable yyresult to record the result.
10044 Use result of setjmp to set it, rather than storing itinto
10046 (yyDone): Remove label.
10047 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
10048 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
10049 if YYABORT is used).
10050 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
10051 yyparse status; put status > 1 into diagnostic.
10052 Check that status==2 works.
10053 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
10054 Use exit status 3 for failure to open (which shouldn't happen).
10056 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
10058 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
10059 1 on syntax error; just let yyparse do its thing.
10060 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
10061 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
10062 (Exploding the Stack Size with Alloca):
10063 (Exploding the Stack Size with Malloc):
10064 Expect exit status 2, not 1, since the parser is supposed to blow
10065 its stack. Problem reported by twlevo@xs4all.nl.
10067 * data/glr.c (yyparse): Don't assume that the initial calls
10068 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
10069 Print a stack-overflow message and fail instead.
10070 Initialize the line-number information before creating the stack,
10071 so that the stack-overflow message can report line zero safely.
10073 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
10075 Fix problems reported by twlevo@xs4all.nl.
10076 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
10077 (yyuserMerge): Provide a default case if b4_mergers is empty.
10078 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
10079 * tests/glr-regression.at
10080 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
10081 Add casts to pacify C++ compilers.
10082 * tests/glr-regression.at (Improper merging of GLR delayed action
10083 sets): Declare yylex before using it.
10084 * tests/Makefile.am (maintainer-check-g++): Fix a stray
10085 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
10086 test for valgrind; valgrind is independent of g++.
10087 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
10088 for compatibility with POSIX 1003.1-2001 (if running coreutils).
10089 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
10090 Use a destructor, so that we can expand the stack. Change
10091 YYSTYPE to char * so that we can free it. Cast result of malloc.
10093 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10095 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
10096 a valgrind failure. Problem reported by twlevo@xs4all.nl.
10098 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
10100 * PACKAGING: New file, suggested by Bruno Haible and taken from
10101 similar wording in gettext's PACKAGING file.
10102 * NEWS: Mention PACKAGING.
10103 * Makefile.am (EXTRA_DIST): Add PACKAGING.
10105 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
10107 * NEWS: Document recent i18n improvements.
10108 * bootstrap: Get runtime translations into runtime-po.
10109 Create runtime-po files automatically, if possible.
10110 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
10111 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
10112 does not infringe on the user's name space.
10113 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
10114 * doc/bison.texinfo (Internationalization): Revamp the English
10115 and Texinfo syntax a bit, to try to make it clearer.
10116 (Bison Options, Option Cross Key): Mention --print-localedir.
10117 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
10118 YYENABLE_NLS. Quote a bit more.
10119 * runtime-po/.cvsignore: New file.
10120 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
10121 * runtime-po/Rules-quot: Remove; now created by bootstrap.
10122 * runtime-po/quot.sed: Likewise.
10123 * runtime-po/boldquot.sed: Likewise.
10124 * runtime-po/en@quot.header: Likewise.
10125 * runtime-po/en@boldquot.header: Likewise.
10126 * runtime-po/insert-header.sin: Likewise.
10127 * runtime-po/remove-potcdate.sin: Likewise.
10128 * runtime-po/Makevars: Likewise.
10129 * runtime-po/LINGUAS: Likewise.
10130 * runtime-po/de.po: Likewise; we will rely on the translation project
10131 to maintain this, so "bootstrap" should get it.
10132 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
10134 * src/main.c (main): Bind the bison-runtime domain, too.
10136 2005-07-12 Bruno Haible <bruno@clisp.org>
10138 * data/yacc.c: Include <libintl.h> when NLS is enabled.
10139 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
10140 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
10141 * runtime-po: New directory.
10142 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
10143 $(DOMAIN).pot-update rule, so that old messages are never dropped.
10144 * runtime-po/Rules-quot: New file, copied from po/.
10145 * runtime-po/quot.sed: Likewise.
10146 * runtime-po/boldquot.sed: Likewise.
10147 * runtime-po/en@quot.header: Likewise.
10148 * runtime-po/en@boldquot.header: Likewise.
10149 * runtime-po/insert-header.sin: Likewise.
10150 * runtime-po/remove-potcdate.sin: Likewise.
10151 * runtime-po/Makevars: New file.
10152 * runtime-po/POTFILES.in: New file.
10153 * runtime-po/LINGUAS: New file.
10154 * runtime-po/bison-runtime.pot: New file.
10155 * runtime-po/de.po: New file.
10156 * m4/bison.m4: New file.
10157 * Makefile.am (SUBDIRS): Add runtime-po.
10158 (aclocaldir, aclocal_DATA): New variables.
10159 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
10161 * src/getargs.c (usage): Document --print-localedir option.
10162 (PRINT_LOCALEDIR_OPTION): New enum item.
10163 (long_options): Add --print-localedir option.
10164 (getargs): Handle --print-localedir option.
10165 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
10166 (Internationalization): New section.
10168 2005-07-12 Akim Demaille <akim@epita.fr>
10170 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
10171 for consistency with the rest of the code.
10172 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
10175 2005-07-12 Akim Demaille <akim@epita.fr>
10177 * src/parse-gram.y: Use %printer instead of YYPRINT.
10179 2005-07-12 Akim Demaille <akim@epita.fr>
10181 * src/symtab.h, src/symtab.c (symbol_print): New.
10182 * src/symlist.h, src/symlist.c (symbol_list_print): New.
10183 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
10185 2005-07-12 Akim Demaille <akim@epita.fr>
10187 * data/glr.c (b4_syncline): Fix (swap) the definitions of
10188 b4_at_dollar and b4_dollar_dollar.
10190 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
10192 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
10193 and Pennello's paper.
10195 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
10197 * data/yacc.c (yyparse): Undo previous patch. Instead,
10198 set yylsp[0] and yyvsp[0] only if the initial action
10199 sets yylloc and yylval, respectively.
10201 * data/yacc.c (yyparse): In the initial action, set
10202 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
10203 This avoids the use of undefined variables if the initial
10204 action does not set yylloc and/or yylval.
10206 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10208 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
10209 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
10210 Remove from CVS. These files are automatically generated.
10211 * examples/extexi: Clarify that this file is now part of Bison,
10212 not GNU M4, and that it works with any POSIX-compatible Awk.
10213 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
10214 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
10215 so that we also get calc++-parser.yy. Geneate it.
10216 Use $(AWK), not gawk, since any conforming Awk will do.
10217 Put comment before action, since older 'make' can't handle comment
10219 $(BUILT_SOURCES): List all built sources, not just some of them.
10220 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
10221 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
10222 $($(calc_sources_generated)): Remove unnecessary test for existence
10223 of target. (This had a shell syntax error anyway; a stray "x".)
10224 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
10226 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
10228 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
10229 implied by the other modules.
10231 2005-07-06 Akim Demaille <akim@epita.fr>
10233 Bind examples/calc++ to the package.
10234 * examples/calc++/Makefile: Remove, replaced by...

10236 * examples/calc++/test: Remove input.
10237 * examples/calc++/compile: Remove.
10238 * examples/Makefile.am: New.

10242 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
10244 * data/glr.c (yyFail): Drastically simplify; since the format argument
10245 never had any % directives, we can simply pass it to yyerror.
10246 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
10247 be modified later, as that is the usual style in glr.c.
10248 Problems reported by Paul Hilfinger.
10250 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
10251 and size overflow errors.
10252 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
10253 in case the user prolog sets feature-test macros like _GNU_SOURCE.
10254 (YYSIZEMAX): New macro.
10255 (yystpcpy): New function, taken from yacc.c.
10256 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
10257 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
10258 so that we don't have to maintain their signatures.
10259 (yyFail): Check for buffer overflow, by using vsnprintf rather
10260 than vsprintf. Allocate a bigger buffer if possible.
10261 Report an error if buffer allocation fails.
10262 (yyStackOverflow): New function.
10263 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
10264 the initialization was successful. It might fail if storage was
10266 (yyexpandGLRStack): Add more checks for storage allocation failure.
10267 Use yyStackOverflow to report failures.
10268 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
10269 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
10270 Don't assume stack number fits in int.
10271 (yysplitStack): Check for storage allocation failure.
10272 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
10273 can print diagnostics on storage allocation failure. All callers
10275 (yyresolveValue): Use yybool for boolean.
10276 (yyreportSyntaxError): Check for size-calculation overflow.
10277 This code is taken from yacc.c.
10278 (yyparse): Check for storage allocation errors when allocating
10281 2005-07-05 Akim Demaille <akim@epita.fr>
10283 Extract calc++ from the documentation.
10284 * doc/bison.texinfo (Calc++): Add the extraction marks.
10285 * examples/extexi: New, from the aborted GNU Programming 2E.
10286 Separate the different paragraph of a file with empty lines.
10287 * examples/Makefile: Use it to extract the whole calc++ example.
10289 2005-06-24 Akim Demaille <akim@epita.fr>
10291 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
10294 2005-06-22 Akim Demaille <akim@epita.fr>
10296 * doc/bison.texinfo (C++ Language Interface): First stab.
10297 (C++ Parsers): Remove.
10299 2005-06-22 Akim Demaille <akim@epita.fr>
10301 * data/lalr1.cc (yylex_): Honor %lex-param.
10303 2005-06-22 Akim Demaille <akim@epita.fr>
10305 Start a set of simple examples.
10306 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
10307 * examples/calc++/calc++-driver.hh,
10308 * examples/calc++/calc++-parser.yy,
10309 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
10310 * examples/calc++/compile, examples/calc++/test: New.
10312 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
10314 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
10315 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
10316 which stems from the 2005-05-27 patch.
10318 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
10320 * data/glr.c: Modify treatment of unused parameters to permit use
10321 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
10323 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
10325 Fix infringement on user name space reported by Janos Zoltan Szabo.
10326 * data/yacc.c (yyparse): strlen -> yystrlen.
10328 2005-05-30 Akim Demaille <akim@epita.fr>
10330 * data/lalr1.cc (_): New.
10331 Translate the various messages.
10333 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
10335 Fix infringement on user name space reported by Bruno Haible.
10336 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
10337 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
10338 the user's name space.
10339 (alloca): Include <stdlib.h> to get it, if it's not built in.
10340 (YYMALLOC, YYFREE): Define only if needed.
10341 (malloc, free): Declare, but only if needed, as this infringes on
10342 the user name space.
10344 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10346 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
10347 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
10349 * lib/ebitset.c (min, max): Undef before defining.
10350 * lib/vbitset.c (min, max): Likewise.
10351 * lib/subpipe.c (create_subpipe): Save local variables in case
10352 vfork clobbers them.
10354 2005-05-24 Bruno Haible <bruno@clisp.org>
10356 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
10357 error message syntax used by gcc-4.0.
10359 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
10361 * README: Mention m4 1.4.3. Remove obsolete advice about
10362 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
10364 * bootstrap: Remove workaround for problem I encountered with
10365 gettext 0.14.1; it seems to be fixed now.
10367 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
10369 * NEWS: Version 2.0a.
10371 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
10372 the previous change.
10374 Various maintainer cleanups.
10375 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
10376 conftest*, for benefit of CVS commands run at the same time as
10377 "configure". Add build-aux, since "bootstrap" now creates it and
10379 * Makefile.cfg (move_if_change): Remove.
10380 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
10381 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
10382 (po_repo, do-po-update, po-update, wget_files, get-targets):
10383 (config.guess-url_prefix, config.sub-url_prefix):
10384 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
10385 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
10386 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
10388 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
10389 this is now the recommended name.
10390 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
10391 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
10392 ylwrap. These files now go into build-aux.
10393 * config/move-if-change: Remove.
10394 * config/prev-version.txt: Bump from 1.75 to 2.0.
10396 * bootstrap: Add stdio-safer, unistd-safer modules.

10400 fopen-safer.c, stdio-safer.h, unistd-safer.h.
10401 * lib/subpipe.c: Include "unistd-safer.h".
10402 (create_subpipe): Make sure all the newly-created
10403 file descriptors are > 2, so that diagnostics don't
10404 get sent down them (which might cause Bison to hang, in theory).
10405 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
10406 * src/files.c (xfopen): Use fopen_safer, not fopen.
10408 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
10409 yesterday's yacc.c fix.
10411 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
10413 * data/glr.c, data/lalr1.cc: Update copyright date.
10415 Fix a destructor bug reported by Wolfgang Spraul in
10416 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
10417 * data/yacc.c (yyabortlab): Don't call destructor, and
10418 don't set yychar to EMPTY.
10419 (yyoverflowlab): Don't call destructor.
10420 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
10421 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
10422 since we no longer output the message "discarding lookahead token
10425 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10427 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
10428 fix a small glitch in debugging output.
10429 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
10430 after YY_SYMBOL_PRINT where needed.
10432 (struct yyGLRState): Add some comments.
10433 (struct yySemanticOption): Add some comments.
10434 (union yyGLRStackItem): Add comment.
10436 (yymergeOptionSets): Correct this to properly perform the union,
10437 avoiding infinite reported by Michael Rosien.
10440 * tests/glr-regression.at: Add test for GLR merging error reported

10481 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
10483 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
10484 Problem reported by Ralf Menzel.
10486 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10488 * tests/actions.at: Test that stack overflow invokes destructors.
10489 From Marcus Holland-Moritz.
10490 * data/yacc.c (yyerrlab): Move the code that destroys the stack
10492 (yyreturn): to here. That way, destructors are called properly
10493 even if the stack overflows, or the user calls YYACCEPT or
10494 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
10495 (yyoverflowlab): Destroy the lookahead.
10497 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
10499 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
10501 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
10503 * NEWS: Bison-generated C parsers no longer quote literal strings
10504 associated with tokens.
10505 * src/output.c (prepare_symbols): Don't escape strings,
10506 since users don't want to see C escapes.
10507 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
10509 * tests/input.at (Torturing the Scanner): Likewise.
10510 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
10512 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
10514 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
10515 the data size is known to be too small and we can't increase it.
10516 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
10518 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
10520 * src/parse-gram.y: Include quotearg.h.
10521 (string_as_id): Quote $1 before using it as a key, since the
10522 lexer no longer quotes it for us.
10523 (string_content): Don't strip quotes, since lexer no longer
10525 * src/scan-gram.l: Include quotearg.h.
10526 ("\""): Omit quote.
10527 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
10528 a key, since the rest of the lexer doesn't quote it.
10529 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
10530 * tests/regression.at (Token definitions): Check for backslashes
10533 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
10534 (YYSIZE_T): Define to unsigned long int when using an older compiler.
10535 (yyparse): Revamp code to generate long syntax error message, to
10536 make it easier to translate, and to avoid problems with arithmetic
10537 overflow. Change "virtual memory" to "memory" in diagnostic, since
10538 we don't know whether the memory is virtual.
10540 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10542 * NEWS: Bison-generated C parsers now use the _ macro to
10544 * data/yacc.c (_) [!defined _]: New macro.
10545 All English strings wrapped inside this macro.
10546 * doc/bison.texinfo (Bison Parser): Document _.
10547 * po/POTFILES.in: Include src/parse-gram.c, since it now
10548 includes translateable strings that parse-gram.y doesn't.
10550 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
10552 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
10553 reverting the 2004-10-11 change to this function.
10554 (symbol_check_alias_consistency): Don't call symbol_type_set
10555 if the type name is already correct.
10556 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
10558 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
10560 * tests/regression.at (Token definitions): Don't use a token named
10561 c, as that generates a "#define c ..." that runs afoul of buggy
10562 stdlib.h that uses the identifier c as a member of struct
10563 drand48_data. Problem reported by Horst Wente.
10565 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
10567 * bootstrap: Change translation URL from
10568 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
10569 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
10570 redirection glitches. Problem reported by twlevo@xs4all.nl.
10572 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
10574 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
10575 after operands; POSIX says this isn't portable for the c99 command.
10577 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
10579 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
10580 immediately if a data overrun has occurred; this may help us track
10581 down what may be a spurious failure on MacOS.
10583 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
10585 Respond to problems reported by twlevo@xs4all.nl.
10587 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
10589 * src/vcg.h: Comment fix.
10590 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
10591 (G_CMAX): Change to -1 instead of INT_MAX.
10593 * data/yacc.c (yyparse): Omit spaces before #line.
10595 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
10597 * src/tables.c (state_number_to_vector_number): Put it inside an
10598 "#if 0", since it's not currently used. Problem reported by
10601 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
10603 * src/output.c (escaped_output): Renamed from
10604 escaped_file_name_output, since we now use it for symbol tags as
10605 well. All uses changed.
10606 (symbol_destructors_output, symbol_printers_output):
10607 Escape symbol tags too.
10608 Problem reported by Matyas Forstner in
10609 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
10611 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
10613 * src/output.c (user_actions_output, token_definitions_output,
10614 symbol_destructors_output, symbol_printers_output): Likewise.
10615 * src/reader.c (prologue_augment): Likewise.
10616 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
10618 * src/vcg.c (output_edge): Don't quote linestyle arg.
10619 Problem reported by twlevo@xs4all.nl.
10621 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
10623 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
10624 example, reported by Derek M Jones. Also, make the example even
10625 more outrageous, to better illustrate how bad the problem is.
10627 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
10629 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
10630 putsym. Typo reported by Sebastian Piping.
10632 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10634 * doc/bison.texinfo (Language and Grammar): some -> same
10635 (Epilogue): int he -> in the
10636 Typos reported by Sebastian Piping via Justin Pence.
10638 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10640 * tests/glr-regression.at (Improper handling of embedded actions
10641 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
10642 embedded actions and $-N in GLR parsers", work around an Autoconf bug
10643 with dollar signs in test names.
10644 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
10645 for a similar reason.
10647 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
10649 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
10650 wants to redefine G_VIEW.
10652 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
10654 * src/vcg.c (get_view_str): Remove case for normal_view.
10655 Problem reported by twlevo@xs4all.nl.
10657 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
10659 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
10660 Problem reported by twlevo@xs4all.nl.
10662 * doc/bison.texinfo: Change @dircategory from "GNU programming
10663 tools" to "Software development". Requested by Richard Stallman
10666 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
10668 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
10669 Problem reported by twlevo@xs4all.nl.
10671 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
10673 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
10674 keyword; it's not needed with modern compilers, and it doesn't
10675 affect correctness with older compilers. Suggested by
10678 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
10680 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
10681 gcc -Wswitch-default.
10682 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10683 * data/yacc.c (yyparse): Likewise.
10685 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
10687 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
10688 already. Let config.h define any nonstandard values.
10690 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
10692 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
10693 for the benefit of slower hosts. Problem reported by
10694 Nelson H. F. Beebe.
10696 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
10698 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
10699 being defined and not used.
10700 * data/lalr1.cc (yyparse): Likewise.
10701 Use "if (false)" rather than "if (0)".
10703 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
10705 * TODO: Mention that we should allow NUL bytes in tokens.
10707 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
10709 * src/scan-skel.l (<<EOF>>): Don't close standard output.
10710 Problem reported by Hans Aberg.
10712 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
10714 * src/getargs.c (version): Happy new year; update overall
10715 program copyright date from 2004 to 2005.
10717 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
10718 Problem reported by Hans Aberg.
10719 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
10720 (Output file names.): Add a test for the case when standard output
10723 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
10725 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
10726 to fix an oversight in the Bison 2.0 manual.
10728 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
10730 * NEWS: Version 2.0. Reformat the existing news items since
10731 1.875, so that related items are grouped together.
10732 * configure.ac (AC_INIT): Bump version to 2.0.
10733 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
10735 * tests/torture.at (Exploding the Stack Size with Alloca): Set
10736 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
10737 otherwise, we're not testing alloca. Unfortunately there's no
10738 simple way to consult HAVE_ALLOCA here.
10740 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
10743 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
10744 hand. This avoids a warning about comparing int to size_t when
10745 GCC warnings are enabled.
10747 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
10749 * NEWS: Bison-generated parsers no longer default to using the
10750 alloca function (when available) to extend the parser stack, due
10751 to widespread problems in unchecked stack-overflow detection.
10752 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
10753 responsibility to set it to a positive value. This lets the user
10754 specify a value that is not a preprocessor constant.
10755 * data/yacc.c (YYMAXDEPTH): Likewise.
10756 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
10757 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
10758 to be a compile-time constant. However, explain the constraints on it.
10759 Also, explain the constraints on YYINITDEPTH.
10760 (Table of Symbols): Explain that alloca is no longer the default.
10761 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
10764 * doc/bison.texinfo (Location Default Action): Mention that n must
10765 be zero when k is zero. Suggested by Frank Heckenbach.
10767 2004-12-22 Akim Demaille <akim@epita.fr>
10769 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
10770 (parser::state_type, parser::semantic_type, parser::location_type):
10771 Private, not public.
10772 (parser::parse): Return ints, not bool.
10773 Returning a bool introduces a problem: 0 corresponds to false, and
10774 it seems weird to return false on success. Returning true changes
10775 the conventions for yyparse.
10776 Alternatively we could return void and send an exception.
10777 There is no clear consensus (yet?).
10778 (state_stack, semantic_stack, location_stack): Rename as...
10779 (state_stack_type, semantic_stack_type, location_stack_type): these.
10780 Private, not public.
10781 * tests/c++.at: New.
10782 * tests/testsuite.at, tests/Makefile.am: Adjust.
10784 2004-12-21 Akim Demaille <akim@epita.fr>
10786 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
10788 2004-12-21 Akim Demaille <akim@epita.fr>
10790 Don't impose std::string for filenames.
10792 * data/lalr1.cc (b4_filename_type): New.
10793 (position::filename): Use it.
10794 (parser.hh): Move the inclusion of stack.hh and location.hh below
10795 the user code, so that needed headers for the filename type can be
10797 Forward declare them before the user code.
10798 * tests/Makefile.am (check-local, installcheck-local): Pass
10799 TESTSUITEFLAGS to the TESTSUITE.
10801 2004-12-20 Akim Demaille <akim@epita.fr>
10803 Use more STL like names: my_class instead of MyClass.
10805 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
10806 (SemanticStack, SemanticType, StateStack, StateType)
10807 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10808 (Parser::value): Rename as...
10809 (location_stack, location_type, rhs_number_type, semantic_stack)
10810 (semantic_type, state_stack, state_type, token_number_type, stack)
10811 (slice, traits, parser::yylloc, parser::yylval): these.
10813 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10815 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10817 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10818 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10820 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10822 Remove uses of 'short int' and 'unsigned short int'. This raises
10823 some arbitrary limits. It uses more memory but nowadays that's
10824 not much of an issue.
10826 This change does not affect the generated parsers; that's a different
10827 task, as some users will want to conserve memory there.
10829 Ideally we should use size_t to represent all object counts, and
10830 something like ptrdiff_t to represent signed differences of object
10831 counts; but that will require more code-cleanup than I have the
10832 time to do right now.
10834 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10835 Use size_t, not int or short int, to count objects.
10836 * src/closure.c (nritemset, closure): Likewise.
10837 * src/closure.h (nritemset, closure): Likewise.
10838 * src/nullable.c (nullable_compute): Likewise.
10839 * src/print.c (print_core): Likewise.
10840 * src/print_graph.c (print_core): Likewise.
10841 * src/state.c (state_compare, state_hash): Likewise.
10842 * src/state.h (struct state): Likewise.
10843 * src/tables.c (default_goto, goto_actions): Likewise.
10845 * src/gram.h (rule_number, rule): Use int, not short int.
10846 * src/output.c (prepare_rules): Likewise.
10847 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
10848 errs, reductions): Likewise.
10849 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
10851 * src/tables.c (vector_number, tally, action_number,
10852 ACTION_NUMBER_MINIMUM): Likewise.
10853 * src/output.c (muscle_insert_short_int_table): Remove.
10855 2004-12-17 Akim Demaille <akim@epita.fr>
10857 * data/lalr1.cc: Extensive Doxygenation.
10858 (error_): Rename as...
10859 (error): this, since it is visible to the user.
10861 (Parser::message): Now an automatic variable from...
10862 (Parser::yyreport_syntax_error_): here.
10863 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10865 * tests/input.at: Escape $.
10867 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
10869 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10870 Parenthesize rhs to avoid obscure problems with mistakes like
10871 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10872 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10873 b4_rhs_location): Likewise.
10874 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10875 b4_rhs_location): Likewise.
10877 2004-12-16 Akim Demaille <akim@epita.fr>
10879 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10880 yacc.c: be sure to stay within yycheck_.
10881 * tests/actions.at: Re-enable C++ tests.
10883 2004-12-16 Akim Demaille <akim@epita.fr>
10885 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
10888 2004-12-16 Akim Demaille <akim@epita.fr>
10890 Use #define to handle the %name-prefix.
10892 * data/glr.c, data/yacc.c: Comment changes.
10893 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10894 so that one can refer to yylex in the parser file, and have it
10895 renamed, as is the case with other skeletons.
10897 2004-12-16 Akim Demaille <akim@epita.fr>
10899 Move lalr1.cc internals into yy*.

10919 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10921 Fix some problems reported by twlevo at xs4all.
10922 * src/symtab.c (symbol_new): Report an error if the input grammar
10923 contains too many symbols. This is better than calling abort() later.
10924 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10925 (struct node, struct graph):
10926 Rename member expand to stretch. All uses changed.
10927 (struct graph): Remove member layoutalgorithm. All uses removed.
10928 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
10929 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
10931 (N_STRETCH): Rename from N_EXPAND. All uses changed.
10933 2004-12-15 Akim Demaille <akim@epita.fr>
10935 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
10936 Add more Doxygen comments.
10937 (symprint_, stack_print_, reduce_print_, destruct_, pop)
10938 (report_syntax_error_, translate_): Rename as...
10939 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
10940 (yypop_, yyreport_syntax_error_, yytranslate_): this.
10942 2004-12-15 Akim Demaille <akim@epita.fr>
10944 * data/lalr1.cc (lex_): Rename as...
10946 Move the trace here.
10947 Take the %name-prefix into account.
10948 Reported by Alexandre Duret-Lutz.
10950 2004-12-15 Akim Demaille <akim@epita.fr>
10952 Simplify the C++ parser constructor.
10954 * data/lalr1.cc (debug_): Rename as...
10955 (yydebug_): so that the parser's internals are always in the yy*
10958 (b4_parse_param_decl): Remove the leading comma as it is now only
10959 called as unique argument list.
10960 (Parser::Parser): Remove the constructor accepting a location and
10961 an initial debugging level.
10962 Remove from the other ctor the argument for the debugging level.
10963 (debug_level_type, debug_level, set_debug_level): New.
10965 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
10968 2004-12-15 Akim Demaille <akim@epita.fr>
10970 Remove b4_root related material: failure experiment
10971 (which goal was to allow to derive from a class).
10973 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
10974 definitions and uses.
10976 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
10978 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
10979 not 2, since it's not portable to subtract 1 from the start of an
10980 array. The new item 0 is never set or used. All uses changed.
10982 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
10983 the default definition of YYLLOC_DEFAULT. Problem reported
10984 by Frank Heckenbach.
10986 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
10988 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
10989 the normal case and one for the error case. Just use the
10990 first one uniformly. Problem reported by Frank Heckenbach.
10991 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
10992 use exactly the same macro in both places.
10993 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
10994 so that the normal-case YYRHSLOC works for the error case too.
10996 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
10997 (YYLLOC_DEFAULT): Use the same macro as glr.c.
10998 * doc/bison.texinfo (Location Default Action): Don't claim that
10999 we have an array of locations. Use the same macro for both glr
11000 and lalr parsers. Mention YYRHSLOC. Mention what happens when
11003 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11005 * HACKING: Update email addresses to send announcements to.
11007 * configure.ac (AC_INIT): Bump version to 1.875f.
11009 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11011 * NEWS: Version 1.875e.
11012 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
11014 * src/scan-skel.l: Include "complain.h", for "fatal".
11016 * src/relation.h (relation_print, relation_digraph):
11017 Relation sizes are of type relation_node, not size_t (this is
11018 merely a doc fix, since the two types are equivalent).
11019 (relation_transpose): Relation sizes are of type relation_node,
11021 * src/relation.c: Likewise.
11022 (top, infinity): Now of type relation_node, not int.
11023 (traverse, relation_transpose): Use relation_node, not int.
11025 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
11026 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
11027 (yyparse): Remove unused local introduced in 2004-10-25 patch.
11029 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
11030 specifying whether the test should be skipped. Use it tp
11031 specify that the [%defines %skeleton "lalr1.cc"] tests currently
11032 fail on some hosts, and should be skipped.
11034 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
11036 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
11037 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
11038 unless otherwise specified below.
11040 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
11041 to allocate kernel_base, kernel_items, kernel_size, since
11042 they needn't be initialized to 0.
11043 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
11044 * src/closure.c (new_closure): Likewise, for itemset.
11045 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

11047 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
11048 (build_relations): Likewise for edge, states1, includes.
11049 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
11050 * src/reader.c (packgram): Likewise, for ritem, rules.
11051 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
11052 * src/relation.c (relation_digraph): Likewise for VERTICES.
11053 (relation_transpose): Likewise for new_R, end_R.
11054 * src/symtab.c (symbols_token_translations_init): Likewise for
11055 token_translations.
11056 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
11057 (token_actions): Likewise for yydefact, actrow, conflrow,
11059 (save_column): Likewise for froms[symno], tos[symno].
11060 (goto_actions): Likewise for state_count.
11061 (pack_table): Likewise for base, pos, check.
11062 (tables_generate): Likewise for width.
11064 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
11065 for initial core. Just have a separate core, so we needn't worry
11066 about whether kernel_size and kernel_base are initialized.
11068 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
11069 kernel_size, kernel_items): Remove unnecessary initialization.
11070 * src/conflicts.c (conflicts): Likewise.
11071 * src/derives.c (derives): Likewise.
11072 * src/muscle_tablc (muscle_insert): Likewise.
11073 * src/relation.c (relation_digraph): Likewise.
11074 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
11075 conflrow, conflict_table, conflict_list, table, check):
11078 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
11079 This is because all callers pass unsigned int.
11080 * src/closure.h (new_closure): Likewise.
11082 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
11083 (build_relations): Initialize includes[i] in all cases.
11084 * src/reader.c (packgram): Always initialize rules[ruleno].prec
11085 and rules[ruleno].precsym. Initialize members in order.
11086 * src/relation.c (relation_transpose): Always initialize new_R[i]
11088 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
11090 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
11091 conflict_list[0] was always 0, but now it isn't initialized.
11093 * src/table.c (table_grow): When conflict_table grew, the grown
11094 area wasn't cleared. Fix this.
11096 * lib/.cvsignore: Add strdup.c, strdup.h.
11097 * m4/.cvsignore: Add strdup.m4.
11099 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
11101 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
11102 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
11103 GOTO_NUMBER_MAXIMUM, since we occasionally compute
11104 ngotos + 1 without checking for overflow.
11105 (build_relations): Use END_NODE, not -1, to denote end of edges.
11106 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
11107 build_relations): Use goto_number, not int, for goto numbers.
11108 * src/tables.c (save_column, default_goto): Likewise.
11110 2004-11-23 Akim Demaille <akim@epita.fr>
11112 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
11113 of #defining from yystype.
11114 Don't typedef yystype, C++ does not need it.
11115 This lets it possible to forward declare it as union.
11117 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
11119 * bootstrap (gnulib_modules): Add extensions.
11120 Problem reported by Jim Meyering.
11122 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
11124 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
11125 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
11126 src/system.h, src/tables.c: XFREE -> free, to accommodate
11127 recent change to gnulib xalloc.h.
11128 Problem reported by Jim Meyering.
11130 2004-11-17 Akim Demaille <akim@epita.fr>
11132 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
11134 2004-11-17 Akim Demaille <akim@epita.fr>,
11135 Alexandre Duret-Lutz <adl@gnu.org>
11137 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
11139 (YYCDEBUG): Adjust.
11140 Use it instead of cdebug_.
11141 (Parser::debug_stream, Parser::set_debug_stream): New.
11142 (Parser::symprint_): Define cdebug_ for temporary backward
11144 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
11147 2004-11-17 Akim Demaille <akim@epita.fr>
11149 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
11150 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
11151 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
11152 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11154 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
11156 * data/glr.c (yyloc_default): Remove; not used.
11157 Problem reported by Frank Heckenbach.
11159 2004-10-25 Akim Demaille <akim@epita.fr>
11161 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
11162 Introduce another definition to address simple location arrays.
11163 (yyGLRStack): New member: yyerror_range.
11164 (yyrecoverSyntaxError, yyparse): Update it.
11165 (yyrecoverSyntaxError): Use it when shifting the error token to
11166 have an accurate range, equivalent to the one computed by both
11167 yacc.c and lalr1.cc.
11168 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
11169 that column numbers start at column 0, as per GNU Coding
11170 Standards, the others tests, and the doc.
11171 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
11172 Adjust to the above change (first column is 0).
11173 And adjust the location of the "<error>", now covering the whole
11176 2004-10-22 Akim Demaille <akim@epita.fr>
11177 and Paul Eggert <eggert@cs.ucla.edu>
11179 Remove some arbitrary limits on goto numbers and relations.
11180 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
11181 initial values, since they're never used.
11182 (set_goto_map): ngotos is now unsigned, so test for overflow
11183 by seeing whether it wraps around to zero.
11184 * src/lalr.h (goto_number): Now size_t, not short int.
11185 (GOTO_NUMBER_MAXIMUM): Remove.
11186 * src/relation.c (relation_print, traverse, relation_transpose):
11187 Check for END_NODE rather than looking at sign.
11188 * src/relation.h (END_NODE): New macro.
11189 (relation_node): Now size_t, not short int.
11191 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
11193 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
11194 keyword, not an identifier. Problem reported by Baron Schwartz in
11195 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
11197 2004-10-11 Akim Demaille <akim@epita.fr>
11199 * src/symtab.c (symbol_check_alias_consistency): Also check
11200 type names, destructors, and printers.
11201 Reported by Alexandre Duret-Lutz.
11202 Recode the handling of associativity and precedence in terms
11203 of symbol_precedence_set.
11204 Accept no redeclaration at all, not even equal to the previous
11206 (redeclaration): New.
11207 Use it to factor redeclaration complaints.
11208 (symbol_make_alias): Don't set the type of the alias, let
11209 symbol_check_alias_consistency do it as for other features.
11210 * src/symtab.h (symbol): Add new member prec_location, and
11212 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
11213 * tests/input.at (Incompatible Aliases): New.
11215 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
11217 .cvsignore fixes to accommodate gnulib changes,
11218 and the practice of naming build directories "_build".
11219 * .cvsignore: Add "_*". Sort.
11220 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
11221 * m4/.cvsignore: Add "*_gl.m4".
11223 2004-10-06 Akim Demaille <akim@epita.fr>
11225 * src/parse-gram.y (add_param): Fix the truncation of trailing
11228 2004-10-05 Akim Demaille <akim@epita.fr>
11230 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11231 whether the reducion was empty or not. This leaves room to
11232 improve the use of YYLLOC_DEFAULT in such a case.
11233 lalr1.cc is still experimental, so changing this is acceptable.
11234 And finally, there are probably not many users who changed the
11235 handling of locations in GLR, so changing is admissible too.
11237 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
11238 empty reduction, set @$ to an empty location ending the previously
11240 Adjust uses to make sure the code is triggered on empty
11242 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
11243 expected output: empty reductions have empty locations.
11245 2004-09-29 Akim Demaille <akim@epita.fr>
11247 * data/lalr1.cc: Move towards a more standard C++ coding style
11248 for templates: Class < T > -> Class<T>.
11250 2004-09-29 Akim Demaille <akim@epita.fr>
11252 * data/lalr1.cc: Reinstall the former ctor, for sake of
11253 compatibility, but warn it will be removed.
11254 Move towards a more standard C++ coding style (i.e., type *var ->
11257 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
11259 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
11260 since it's less likely to work if NULs are involved in the future.
11262 2004-09-27 Akim Demaille <akim@epita.fr>
11264 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
11266 2004-09-27 Akim Demaille <akim@epita.fr>
11268 * data/lalr1.cc (b4_parse_param_decl_1): New.
11269 (b4_parse_param_decl): Use it to have different names between attribute
11270 and argument names.
11271 (b4_cc_constructor_call): Likewise.
11273 2004-09-24 Akim Demaille <akim@epita.fr>
11275 * src/parse-gram.y (add_param): Strip the leading and trailing
11276 blanks from a formal argument declaration.
11277 (YY_LOCATION_PRINT): New.
11279 2004-09-24 Akim Demaille <akim@epita.fr>
11281 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
11282 after the location.
11284 2004-09-24 Akim Demaille <akim@epita.fr>
11286 * doc/bison.texinfo (Table of Symbols): Sort.
11288 2004-09-21 Akim Demaille <akim@epita.fr>
11290 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
11291 the useless parentheses.
11292 Suggested by Paul Eggert.
11294 2004-09-20 Akim Demaille <akim@epita.fr>
11296 Let the initial-action act on the look-ahead, and use it for the
11297 "initial push" (corresponding to an hypothetical beginning-of-file).
11298 And let lalr1.cc honor %initial-action.
11300 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
11302 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
11303 (Parser::Parser): Remove the ctor that used to initialize it.
11304 (Parser::parse): Like in the other skeletons, issue the "starting
11305 parse" message before any action.
11306 Honor %initial-action.
11307 Initialize the stacks with the lookahead.
11308 * data/yacc.c: Let $$ and @$ in %initial-action designate the
11310 Push them in the stacks.
11311 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
11313 2004-09-20 Akim Demaille <akim@epita.fr>
11315 * doc/bison.texinfo (Initial Action Decl): New.
11317 2004-09-20 Akim Demaille <akim@epita.fr>
11319 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
11320 clearer criterion to define it.
11321 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
11322 When reducing on an empty RHS, use the latest stacked location as
11324 yylloc is not always available.
11325 * data/glr.c: Likewise.
11326 Also, honor initial-actions.
11328 2004-09-20 Akim Demaille <akim@epita.fr>
11330 * data/yacc.c (YY_LOCATION_PRINT): New.
11331 Define when we know YYLTYPE's structure, i.e., when the default
11332 YYLLOC_DEFAULT is used.
11333 * data/c.m4 (b4_yysymprint_generate): Use it.
11334 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
11335 value of the result.
11336 (error_start_): Replace with...
11337 (error_range_): this location array.
11338 This allows to replace code relying on the implementation of
11339 locations by portable code.
11340 * data/yacc.c (yylerrsp): Replace with...
11341 (yyerror_range): this.
11342 Every time a token is popped, update yyerror_range[0], to have an
11343 accurate location for the error token.
11344 * data/glr.c (YY_LOCATION_PRINT): New.
11345 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
11346 deference a pointer.
11347 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
11348 report the location in %printers.
11350 * src/scan-skel.l: Instead of abort, report error messages to ease
11351 understanding skeleton scanning failures.
11353 2004-09-16 Akim Demaille <akim@epita.fr>
11355 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
11356 (iterator, const_iterator): these, to be more in the C++ spirit.
11357 Also, return reverse iterators so that when displaying the stack
11358 we display its bottom first.
11359 (Parser::stack_print_, Parser::reduce_print_): Match the messages
11361 We should probably use vector here though.
11363 2004-09-16 Akim Demaille <akim@epita.fr>
11365 Have more complete shift traces.
11367 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
11368 to report Shifts instead of ad hoc YYDPRINTF invocations,
11369 including for the error token.
11370 * data/lalr1.cc (symprint_): Output the location.
11371 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
11372 output the location within the %printer.
11373 Activate GLR tests, at least to make sure they compile properly.
11374 They still don't pass though.
11375 * tests/calc.at: Adjust expect verbose output, since now "Entering
11376 state..." is on a different line than the "Shifting" message.
11378 2004-09-08 Akim Demaille <akim@epita.fr>
11380 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
11381 Bison directive from the Bison file to the invocation of this
11382 macro, so that these directives are passed to
11383 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
11384 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
11385 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11386 the extra Bison directives instead of the whole series.
11387 Change the grammar so that there are recoverable errors, and
11388 unrecoverable errors. Now we can have the parser give up before
11389 consuming the whole input. As a result we now can observe that
11390 the lookahead is freed when needed.
11391 Change the parser source to parse argv[1] instead of a hard coded
11393 Simplify yylex, and give a value and location to EOF.
11394 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11395 passed directives already coded in the file.
11396 Add some tests to check the location of "error".
11397 For some tests, the C++ parser is correct, and not yacc.c.
11398 For other tests, they provide different, but unsatisfying, values,
11399 so keep the C++ value so that at least one parser is "correct"
11400 according to the test suite.
11401 (Actions after errors): Remove, this is subsumed by the
11402 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
11404 2004-09-06 Akim Demaille <akim@epita.fr>
11406 * data/lalr1.cc: Adjust the indentation of the labels.
11407 (Parser::pop): New.
11410 2004-09-06 Akim Demaille <akim@epita.fr>
11412 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
11413 argument, an informative message.
11414 Call YY_SYMBOL_PRINT.
11415 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
11416 * data/lalr1.cc (destruct_): Likewise.
11417 In addition, no longer depend on b4_yysymprint_generate and
11418 b4_yydestruct_generate to generate these functions, do it "by
11421 2004-09-03 Akim Demaille <akim@epita.fr>
11423 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
11424 invoked, yydestruct the lookahead.
11425 * tests/calc.at (Calculator $1): Update the expected lengths of
11426 traces: there is an added line for the discarded lookahead.
11427 * doc/bison.texinfo (Destructor Decl): Some rewording.
11428 Define "discarded" symbols.
11430 2004-09-02 Akim Demaille <akim@epita.fr>
11432 * data/lalr1.cc (translate_, destruct_): No reason to be static.
11434 2004-09-02 Akim Demaille <akim@epita.fr>
11436 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
11437 (YYDSYMPRINTF): Rename as...
11438 (YY_SYMBOL_PRINT): this.
11439 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
11441 Use it instead of direct symprint_ calls.
11442 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
11445 2004-09-02 Akim Demaille <akim@epita.fr>
11447 * data/lalr1.cc (b4_yysymprint_generate): New.
11448 (symprint_): New member function, defined when YYDEBUG.
11449 Use it consistently instead of token/nterm debugging output by
11451 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
11452 %printer calls to use cdebug_ when using lalr1.cc.
11454 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
11456 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
11457 with #ifdef YYDEBUG.
11459 2004-08-26 Akim Demaille <akim@epita.fr>
11461 * doc/bison.texinfo (Implementing Loops): Rename as...
11462 (Implementing Gotos/Loops): this.
11464 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
11466 Adjust to latest gnulib.
11467 * bootstrap (gnulib_modules): Add xalloc-die.
11468 Set LC_ALL=C so that file names sort consistently.
11469 Prefer the gnulib copies of gettext.m4, glibc21.m4,
11470 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
11471 uintmax_t.m4, ulonglong.m4.
11472 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
11473 po.m4 since we are now using _gl.m4 instead.
11475 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
11477 * src/scan-action.l: Remove. Scanning of semantic actions is
11478 handled in scan-gram.l.
11480 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
11482 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
11484 * src/location.h (struct): The file member is a uniqstr.
11485 (equal_boundaries): Use UNIQSTR_EQ for comparison.
11487 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
11489 Fix bug with non-%union parsers that have printers or destructors,
11490 which led to a Bison core dump. Reported by Peter Fales in
11491 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
11493 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
11494 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
11495 not to our own type.
11496 * src/output.c (symbol_destructors_output, symbol_printers_output):
11497 Don't assume %union.
11498 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
11499 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
11500 UNION-FLAG. All callers changed.
11501 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
11502 Use type char, not unsigned int, when declaring an array of char;
11503 this lets us remove a cast.
11504 (Printers and Destructors): Add non-%union test cases.
11506 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11508 * doc/bison.texinfo: Minor editorial changes, mostly to the new
11509 GLR writeups. E.g., avoid frenchspacing and the future tense,
11510 change "lookahead" to "look-ahead", and change "wrt" to "with
11513 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11515 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
11516 New sections, split off from the GLR Parsers section. Put the new
11517 Simple GLR Parser near the start of the GLR section, for clarity.
11518 Rewrite connective text.
11520 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
11522 * doc/bison.texinfo (Simple GLR Parsers): New section.
11524 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11526 * NEWS, TODO, doc/bison.texinfo:

11555 Don't assume the C++ compiler takes the same arguments as the C compiler
11557 * configure.ac (O0CXXFLAGS): New var.
11558 * tests/atlocal.in (CXXFLAGS): Use it.
11560 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
11562 Fix some "make check" problems with C++ reported by
11563 Albert Chin-A-Young for Tru64 C++ in this thread:

11576 C++ compiler. (trivial change)
11578 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
11580 Spent a few hours checking out which prerequisite versions the
11581 current sources actually require. I went all the way back to
11582 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
11583 a seemingly endless set of combinations of versions more recent
11584 than that. The bottom line is that the current sources require
11585 fairly recent versions of the build tools, and it'll be some work
11587 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
11588 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
11589 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
11590 Add comments explaining why those particular versions are
11593 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
11594 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
11595 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
11597 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
11598 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
11600 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11602 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
11603 0.11.5. Suggested by Bruno Haible.
11604 * bootstrap: Remove gettext version checking.
11606 * doc/bison.texinfo (Decl Summary): Also mention that %union
11607 can depend on prerequisite types. Problem reported by Tim
11610 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11612 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
11613 * README-alpha: Don't tell people not to package this.
11615 * bootstrap: Don't assume $(...) works; use `...` instead.
11616 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
11619 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
11620 put into the -d output file, and mention what to do if YYSTYPE is
11621 defined as a macro.
11623 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11625 Undo change made earlier today: it caused autopoint to not bring
11626 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
11629 * bootstrap: Check that gettext version matches what's in
11630 configure.ac. Warn users to ignore robots.txt ERROR 404.
11631 * bootstrap: Undo today's earlier change (logged below).
11632 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
11634 The gettext version checking is causing more trouble than it's
11635 curing; remove it. Problem reported by Paul Hilfinger.
11637 * bootstrap: Issue a warning that one can expect a message
11638 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
11639 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
11641 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
11643 Ensure that the C++ compiler used for testing actually works on a
11644 simple test program; if not, skip the C++-related tests. Problem
11645 reported by Vin Shelton in:
11646 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
11648 * m4/cxx.m4: New file.

11653 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
11655 * data/glr.c (yylloc): Output this macro even if locations are not
11656 being generated, as the GLR parser needs it even in that case.
11657 Problem reported by Troy A. Johnson
11658 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
11660 * configure.ac (AC_INIT): Update to 1.875e.

11664 * NEWS: Version 1.875d.
11665 * configure.ac (AC_INIT): Likewise.
11666 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
11668 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
11669 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
11670 lalr1.cc runs afoul of the first, and the last two are no longer
11671 supported by GCC 3.4.0.
11672 * README: Mention GNU m4 1.4 or later; mention m4 patches.
11673 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
11675 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
11677 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
11678 unsigned int, for compatibility with latest gnulib hash module.
11679 * src/state.c (state_hash, state_hasher): Likewise.
11680 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
11681 * src/uniqstr.c (hash_uniqstr): Likewise.
11683 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
11685 * NEWS: Unescaped newlines are no longer allowed in char & strings.
11687 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
11688 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
11689 character and string literals.
11690 (unexpected_end): New function.
11691 (unexpected_eof): Use it.
11692 (unexpected_newline): New function.
11693 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
11696 * NEWS: Document %expect-rr.
11698 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
11699 Fix typo by replacing $1 with $option.
11700 Remove more 'intl'-related files.
11701 Don't DEFUN AM_INTL_SUBDIR twice.
11703 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
11704 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
11706 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
11707 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
11708 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
11709 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
11710 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
11711 * src/.cvsignore: Add *.output.
11713 * src/parse-gram.y: Put copyright notice inside %{ %} so it
11714 gets copied to the output file.
11716 2004-04-28 Paul Eggert <eggert@twinsun.com>
11718 Get files from the gnulib and po repositories, instead of relying
11719 on them being in our CVS. Upgrade to latest versions of gnulib
11722 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
11723 * bootstrap: Bootstrap from gnulib and po repositories.
11724 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11725 * README-cvs: Document these changes. Remove version numbers from
11726 mentions of build tools, since they change so often. Mention Flex.
11728 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
11729 (gl_USE_SYSTEM_EXTENSIONS): Add.
11730 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
11731 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
11733 (AC_ISC_POSIX): Remove; we no longer support this
11734 ancient OS, as it gets in the way of latest Autoconf & gnulib.
11735 (AC_HEADER_STDC): Remove: we now assume C89 or better.
11736 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
11737 Do not check for C89 headers, except for locale.h which is used
11738 by the Yacc library and must port to K&R hosts.
11739 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
11740 Do not check for C89 functions, except for setlocale which is
11741 used by the Yacc library.
11742 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
11743 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
11744 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,

11746 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
11747 AM_GNU_GETTEXT): Remove; now done by:
11748 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
11749 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
11752 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
11753 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
11754 Define to empty, as gnulib.mk will do the rest for us.
11755 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
11757 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
11758 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
11760 * src/files.c: Include gnulib's xstrndup.h.
11762 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
11763 (REALLOC): Use xnrealloc, for likewise.
11764 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
11765 (strnlen, memrchr): Remove decls; functions no longer used.

11790 by bootstrap or automake.
11792 * po/ChangeLog: Remove: all but one entry was a duplicate
11793 of this file, and I moved that 2000-11-02 entry here.

11818 2004-04-27 Paul Eggert <eggert@twinsun.com>
11820 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
11821 case, as stos_ is now used by destructors due to the 2004-02-09
11824 Remove more K&R C support.
11825 * lib/libiberty.y (PARAMS): Remove. All uses removed.

11843 with latest obstack.h.
11844 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args

11848 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,

11852 test whether it can stand alone.

11858 * tests/synclines.at (%union synch line): Put a dummy member in
11859 the union, because empty unions aren't allowed in C. Caught
11862 2004-04-13 Jim Meyering <jim@meyering.net>
11864 * src/conflicts.c (conflicts_print): Correct format string typo:

11921 expected_conflicts.
11922 (expected_rr_conflicts): Define.
11923 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
11925 Use expected_sr_conflicts in place of expected_conflicts.
11926 Warn if expected_rr_conflicts used in non-GLR parser.
11928 * doc/bison.texinfo: Add documentation for %expect-rr.
11930 2004-03-08 Paul Eggert <eggert@gnu.org>
11932 Add support for hex token numbers. Suggested by Odd Arild Olsen in
11933 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
11935 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
11937 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
11938 * src/scan-gram.l (scan_integer): New function.
11940 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
11941 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
11942 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
11943 Say "long int", not "long", for uniformity with GNU style.
11945 2004-02-25 Paul Eggert <eggert@twinsun.com>
11947 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
11948 compilers. This fixes a problem with Intel's C++ compiler being
11949 chatty, reported by Guido Trentalancia in
11950 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
11952 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
11954 Support %destructor and merge error locations in lalr1.cc.
11956 * data/lalr1.cc (b4_cxx_destruct_def): New macro.

11966 token so that it covers all the discarded tokens.
11967 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
11968 it can be called with `%skeleton "lalr1.cc"', and do that.
11970 2004-02-02 Paul Eggert <eggert@twinsun.com>
11972 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
11973 $(top_srcdir)/lib and ../lib. This fixes a bug reported
11974 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
11975 There's no need to mention top_builddir since Automake does that
11977 (INCLUDES): Remove, as Automake says it's obsolescent.
11978 Contents migrated into AM_CPPFLAGS as described above.
11979 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
11981 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11983 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
11984 (yyreportSyntaxError): Handle case where lookahead token is
11987 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11989 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
11990 resulting parsers are compilable with C++.
11992 2003-12-23 Paul Eggert <eggert@twinsun.com>
11994 * config/depcomp, config/install-sh: Sync with Automake 1.8.
11995 * src/output.c (output_skeleton): Rename local var.
11996 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
11997 Bison tokens, as this runs afoul of the 2003-10-07 change that
11998 disallowed NUL bytes in character constants or string literals.
12000 * tests/local.at: Require Autoconf 2.59's Autotest.
12001 * tests/testsuite.at: Don't include local.at, since we now assume
12002 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
12004 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
12005 multiple inclusion warnings.
12007 2003-12-02 Akim Demaille <akim@epita.fr>
12009 * doc/bison.texinfo (How Can I Reset the Parser): More about start
12013 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>

12017 2003-10-07 Paul Eggert <eggert@twinsun.com>
12019 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
12020 if testsuite doesn't exist.
12022 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
12023 literals, unfortunately.
12024 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
12025 Complain about NUL bytes in character constants or string literals.
12027 2003-10-05 Paul Eggert <eggert@twinsun.com>
12029 * NEWS: Don't document %no-default-prec, as it's still
12031 * doc/bison.texinfo: Document %no-default-prec only if
12032 the defaultprec flag is set. Normally it's not.
12034 2003-10-04 Paul Eggert <eggert@twinsun.com>
12036 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
12037 non-modifiable lvalue, instead of a modifiable one.
12038 * doc/bison.texinfo (Actions): Document that $$ can
12039 be assigned to. Do not claim that $$ and $N are
12040 array element references: user code should not rely on this.
12042 2003-10-01 Paul Eggert <eggert@twinsun.com>
12044 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

12050 2003-10-01 Akim Demaille <akim@epita.fr>
12052 VCG no longer supports long_straight_phase.
12054 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
12055 * src/print_graph.c (print_graph): Adjust.
12057 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
12058 and Paul Eggert <eggert@twinsun.com>
12060 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
12061 Table of Symbols): Document %default-prec.
12062 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.

12067 (packgram): Handle it.
12068 * tests/conflicts.at (%default-prec without %prec,
12069 %default-prec with %prec, %default-prec 1): New tests.
12071 2003-09-30 Paul Eggert <eggert@twinsun.com>

12074 a typo in the 2003-08-25 patch.
12076 2003-08-27 Akim Demaille <akim@epita.fr>
12078 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
12081 2003-08-26 Akim Demaille <akim@epita.fr>
12083 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
12084 "<\#" to avoid magic from Gnus when posting parts of this script.
12086 2003-08-26 Akim Demaille <akim@epita.fr>
12088 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
12089 (Parser::parse): here.
12090 Adjust: nerrs and errstatus is now replaced by...
12091 (Parser::nerrs_, Parser::errstatus_): New.
12093 2003-08-25 Akim Demaille <akim@epita.fr>
12095 * config/announce-gen, Makefile.cfg: New.
12096 * Makefile.am: Adjust.
12097 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
12098 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
12100 2003-08-25 Akim Demaille <akim@epita.fr>
12102 When reducing initial empty rules, Bison parser read an initial
12103 location that is not defined. This results in garbage, and that
12104 affects Bison's own parser. Therefore we need (i) to extend Bison
12105 to support a means to initialize this location, and (ii) to use
12106 this CVS Bison to fix CVS Bison's parser.
12108 * src/reader.h, reader.c (epilogue_augment): Remove, replace
12110 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
12111 * src/parse-gram.y: Adjust.
12112 (%initial-action): New.
12113 (%error-verbose): Since we require CVS Bison, there is no reason
12115 * src/scan-gram.l: Adjust.
12116 * src/Makefile.am (YACC): New, to make sure we use our own parser.
12117 * data/yacc.c (yyparse): Use b4_initial_action.
12119 2003-08-25 Akim Demaille <akim@epita.fr>
12121 * doc/bison.texinfo: Don't promote stdout for error messages.
12123 2003-08-25 Akim Demaille <akim@epita.fr>
12125 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
12126 From Alexandre Duret-Lutz.
12128 2003-08-25 Akim Demaille <akim@epita.fr>
12132 2003-08-25 Akim Demaille <akim@epita.fr>
12134 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
12137 2003-08-25 Akim Demaille <akim@epita.fr>
12139 * data/lalr1.cc (Parser::reduce_print_): New.
12142 2003-08-25 Akim Demaille <akim@epita.fr>
12144 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
12145 error recovery loops. This patch is based on
12146 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
12147 Also, augment the similarity between lalr1.cc and yacc.c.
12148 Note: the locations of error recovery rules are not correct yet.
12150 * data/lalr1.cc: Comment changes to augment the similarity between
12151 lalr1.cc and yacc.c.
12152 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
12153 (yyerrlab1): Remove, but where it used to be (now the bottom part of
12154 yyerrlab), when hitting EOF, pop the whole stack here instead of
12155 merely falling thru the default error handling mechanism.
12156 (yyerrorlab): New label, with the old contents of YYERROR,
12157 plus the following change: pop the stack of rhs corresponding
12158 to the production that invoked YYERROR. That is how Yacc
12159 behaves (required by POSIX).
12160 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
12163 2003-08-25 Akim Demaille <akim@epita.fr>
12165 Tune local.at so that people can "autom4te -l autotest calc.at -o
12166 calc" for instance, to extract a sub test suite.
12168 * tests/testsuite.at: Move the initialization, Autotest version
12169 requirement, and AT_TESTED invocation into...
12170 * tests/local.at: here.
12171 * tests/testsuite.at: Include it for compatibility with Autoconf
12173 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
12176 2003-08-04 Paul Eggert <eggert@twinsun.com>
12178 Rework code slightly to avoid gcc -Wtraditional warnings.
12179 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
12180 The returned value is now stored in *YY0. All callers changed.
12181 * src/output.c (merge_output): Adjust to the above change.
12183 2003-07-26 Paul Eggert <eggert@twinsun.com>
12185 * data/glr.c (YYASSERT): New macro.
12186 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
12187 yyresolveStates, yyprocessOneStack):
12188 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
12189 Derived from a suggestion by Frank Heckenbach.
12191 2003-07-25 Paul Eggert <eggert@twinsun.com>
12193 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
12194 for portability to K&R C (after ansi2knr, presumably). See
12195 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
12196 by Frank Heckenbach, though I have omitted the structure-initialization
12197 part of his glr-knr.diff patch since I recall that the Portable
12198 C Compiler didn't require that change.
12200 Let the user specify how to allocate and free memory.
12201 Derived from a suggestion by Frank Heckenbach in
12202 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
12203 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
12204 All uses of free, malloc, realloc changed to use these macros,
12205 and unnecessary casts removed.
12206 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
12208 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
12210 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
12211 use s.empty() rather than s == "" to test for empty string; see
12212 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
12215 2003-06-25 Akim Demaille <akim@epita.fr>
12217 * config/depcomp, config/install-sh: Update from masters.
12219 2003-06-20 Paul Eggert <eggert@twinsun.com>
12221 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
12222 and return properly parenthesized result.
12223 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
12224 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
12225 Remove unnecessary parentheses from uses.

12227 conventions for parentheses.
12229 2003-06-19 Paul Eggert <eggert@twinsun.com>
12231 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
12232 yyreportTree): Do not assume that size_t is the same width as int,
12233 when printing sizes. Print sizes using an unsigned format.
12234 Problem reported by Frank Heckenbach in
12235 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
12237 Port to Forte Developer 7 C compiler.
12238 * data/glr.c (struct YYLTYPE): If locations are not being used,
12239 declare a single dummy member, as empty structs do not conform
12241 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
12242 the Forte Developer 7 C compiler complains that end-of-loop
12243 code is not reached.
12245 2003-06-17 Paul Eggert <eggert@twinsun.com>
12247 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
12248 avoid warnings from picky compilers about redefinition of PARAMS.
12250 2003-06-17 Paul Eggert <eggert@twinsun.com>
12254 * NEWS: Document 1.875b.
12256 * lib/bbitset.h: Do not include config.h; that's the includer's job.
12257 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
12258 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
12259 Don't use 'index' in comments, as it's a builtin fn on some hosts.
12260 * lib/bitset_stats.c: Include gettext.h unconditionally, as
12261 per recent gettext manual's suggestion.
12262 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
12263 Use prototypes, not old-style definitions.
12264 * lib/lbitset.c (lbitset_unused_clear): Likewise.
12265 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,

12270 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
12271 vbitset_or_and_cmp, vbitset_copy): Likewise.
12273 * lib/libiberty.h: Do not include config.h; that's the includer's job.
12274 Do not include <stdlib.h>.
12275 (PARAMS): Define unconditionally for C89.
12276 (ATTRIBUTE_NORETURN): Remove.
12277 (ATTRIBUTE_UNUSED): Define unconditionally.
12279 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
12280 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
12281 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
12282 * lib/vbitset.c, lib/vbitset.h: New files.
12283 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
12284 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
12287 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
12288 `How Can I Reset @code{yyparse}', since texinfo does not allow
12289 arbitrary @ in node names.
12291 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
12292 shouldn't be needed according to the gettext 0.12.1 documentation
12293 but which seem to be needed anyway: codeset.m4 glibc21.m4
12294 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
12295 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
12296 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
12298 * lib/.cvsignore: Add stdbool.h.
12299 * m4/.cvsignore: Add nls.m4, po.m4.
12301 Upgrade to CVS gnulib.
12302 * stdbool_.h: File renamed from stdbool.h.in.
12303 * configure.ac (AM_STDBOOL_H): Invoke this instead of
12305 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
12306 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
12307 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
12308 (MOSTLYCLEANFILES): New var.
12309 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
12310 (stdbool.h): New rule.
12311 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
12312 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
12313 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
12314 m4/quote.m4: Upgrade to today's gnulib.
12316 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
12317 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
12318 the tests right now.
12319 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
12320 yyerror are declared before use; C99 requires this.
12322 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12324 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
12326 (yyrecoverSyntaxError): Correct the logic for setting and testing
12328 Correct comment on handling EOF.
12329 Allow states with only a default reduction, rather than failing
12330 (I can't quite reconstruct why these were not allowed before).
12332 Fixes to avoid problem that $-N rules in GLR parsers can cause
12333 buffer overruns, corrupting state.
12335 * src/output.c (prepare_rules): Output max_left_semantic_context
12337 * src/reader.h (max_left_semantic_context): New variable declaration.
12338 * src/scan-gram.l (max_left_semantic_context): Define.
12339 (handle_action_dollar): Update max_left_semantic_context.
12340 * data/glr.c (YYMAXLEFT): New definition.
12341 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
12342 (yyresolveAction): Ditto.
12344 Fixes to problems with location handling in GLR parsers reported by
12345 Frank Heckenbach (2003/06/05).
12347 * data/glr.c (YYLTYPE): Make trivial if locations not used.
12348 (YYRHSLOC): Add parentheses, and define only if locations used.
12349 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
12350 locations not used.
12351 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
12352 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
12354 * tests/cxx-type.at: Exercise location information; update tests
12355 to differentiate output with and without locations.
12356 Remove forward declarations of yylex and yyerror---caused errors
12357 because default YYLTYPE not yet defined.
12358 Change semantic actions to compute strings, rather than printing
12359 them directly (to test proper passing of semantics values). Change
12360 output to prefix notation and update test data and expected results.
12361 (yylex): Track locations.
12362 (stmtMerge): Return value rather than printing, and include arguments
12365 2003-06-03 Paul Eggert <eggert@twinsun.com>
12367 Avoid warnings generated by GCC 2.95.4 when Bison is
12368 configured with --enable-gcc-warnings.
12369 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
12370 yy::]b4_parser_class_name[::translate_,
12371 yy::Stack::operator[] (unsigned),
12372 yy::Stack::operator[] (unsigned) const,
12373 yy::Slice::operator[] (unsigned),
12374 yy::Slice::operator[] (unsigned) const):
12375 Rename local vars to avoid warnings.
12376 * tests/glr-regression.at (Improper handling of embedded actions
12377 and $-N in GLR parsers): Remove unused local variable from yylex.
12378 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
12379 (void) as arg when not pure, since we now assume C89 when building
12380 Bison. Pacify GCC by using parameter.
12382 2003-06-02 Paul Eggert <eggert@twinsun.com>
12384 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
12385 yy::Location::lines, yy::Location::columns): Rename arguments
12386 to avoid shadowing; this removes a warning generated by GCC 3.3.
12388 2003-06-01 Paul Eggert <eggert@twinsun.com>
12390 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
12391 to g++, as GCC 3.3 complains if you do it.
12392 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
12393 everything that WARNING_CFLAGS has, except omit warnings
12394 not suitable for C++.
12395 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
12396 * tests/atlocal.in (CXXFLAGS): New var.
12397 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
12399 Fix a GLR parser bug I reported in February; see
12400 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
12401 The problem was that GLR parsers did not conform to the C standard,
12402 because actions like { $1 = $2 + $3; } expanded to expressions
12403 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12404 to a local variable. The C standard says that expressions
12405 like (var = f ()) + (var = f ()) have undefined behavior.
12406 Another problem was that GCC sometimes issues warnings that
12407 yyfill and its parameters are unused.
12409 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12410 as possibly unused.
12411 (yyfill): New function.
12413 (yyuserAction): Change type of yynormal to bool, so that it matches
12414 the new yyfill signature. Mark it as possibly unused.
12417 Follow up on a bug I reported in February, where a Bison-generated
12418 parser can loop. Provide a test case and a fix for yacc.c. I
12419 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12420 The original bug report is in:
12421 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
12423 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12424 macro's size was becoming unwieldy.
12425 (yyerrlab): Do not discard an empty lookahead symbol, as this
12426 might destroy garbage.
12427 (yyerrorlab): New label, with the old contents of YYERROR,
12428 plus the following change: pop the stack of rhs corresponding
12429 to the production that invoked YYERROR. That is how Yacc
12430 behaves, and POSIX requires this behavior.
12431 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12432 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12433 Define 'alarm' to do nothing if unistd.h is not available.
12434 Add a new rule "exp: '-' error;" to test the above change to
12435 data/yacc.c. Use 'alarm' to abort any test taking longer than
12436 10 seconds, as it's probably looping.
12437 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12438 Also, the new yacc.c generates two fewer diagnostics for an
12441 2003-05-24 Paul Eggert <eggert@twinsun.com>
12443 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
12444 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
12445 This fixes a problem reported by John Bowman when the Compaq/HP
12446 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
12447 -ansi -Wall -gall).
12448 * data/yacc.c (union yyalloc): Likewise.
12449 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
12451 Switch from 'int' to 'bool' where that makes sense.
12453 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,

12456 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
12457 Return or accept bool, not int. All callers changed.

12477 lbitset_xor_cmp): Likewise.
12478 * lib/bbitset.h: Include <stdbool.h>.
12479 (struct bitset_vtable): The following members now return bool, not
12480 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
12481 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,

12514 2003-05-14 Paul Eggert <eggert@twinsun.com>
12516 * src/parse-gram.y (rules_or_grammar_declaration): Require a
12517 semicolon after a grammar declaration, in the interest of possible
12518 future changes to the Bison input language.
12519 Do not allow a stray semicolon at the start of the grammar.
12520 (rhses.1): Allow one or more semicolons after any rule, including
12521 just before "|" as required by POSIX.
12522 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
12525 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
12527 %parse-param support for lalr1.cc.
12529 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
12530 b4_cc_constructor_calls, b4_cc_constructor_call,
12531 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
12533 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
12534 parse-param arguments.
12535 (yy::b4_parser_class_name): Declare instance variables to
12536 hold parse-param arguments.
12537 * tests/calc.at: s/value/semantic_value/ because value clashes
12538 with a member of yy::b4_parser_class_name. Adjust C++ code
12539 to handle %parse-param. Enable %parse-param test in C++.
12541 2003-05-12 Paul Eggert <eggert@twinsun.com>
12543 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
12544 English a bit. Fix fclose typo. Change "const char" to "char
12545 const", and use ANSI C rather than K&R for "main". Suggest
12546 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
12547 and suggest yy_switch_to_buffer.
12549 2003-05-05 Paul Eggert <eggert@twinsun.com>
12551 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
12552 C89. This avoids a diagnostic on compilers that define __STDC__
12553 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
12554 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12556 2003-05-03 Paul Eggert <eggert@twinsun.com>
12558 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
12559 Do not overrun array bounds.
12560 This should fix a bug reported today by Olatunji Oluwabukunmi in
12561 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
12563 2003-04-29 Akim Demaille <akim@epita.fr>
12565 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
12566 * src/getargs.c, src/getargs.h: here, as bool, not int.
12567 (nondeterministic_parser): New.
12568 * src/parse-gram.y, src/scan-gram.l: Support
12569 %nondeterministic-parser.
12570 * src/output.c (prepare): Use nondeterministic_parser instead
12571 of glr_parser where appropriate.
12572 * src/tables.c (conflict_row, action_row, save_row)
12573 (token_actions, token_actions, pack_vector): Ditto.

12582 with %pure-parser and %locations to exercise the patch from Yakov
12585 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
12587 * data/yacc.c: (b4_lex_param): Corrected for the case where
12588 %lex-param is provided and %pure-parser isn't.
12590 2003-04-27 Paul Eggert <eggert@twinsun.com>
12592 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
12593 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
12594 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
12595 if it is not defined.
12596 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
12598 2003-04-26 Paul Eggert <eggert@twinsun.com>
12600 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
12601 Declare to be of type suitable for the ninf value itself, not of
12602 type suitable for the corresponding table, since the latter might
12603 be unsigned but the ninf value might be negative. This fixes a
12604 bug reported by Alexandre Duret-Lutz in
12605 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
12607 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
12608 invokes it. We shouldn't invoke it twice because it will attempt
12609 to put error.o in the archive twice. This fixes a glitch reported
12610 by Martin Mokrejs in
12611 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12613 2003-04-21 Paul Eggert <eggert@twinsun.com>
12615 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
12618 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
12620 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
12621 Fix obvious typo that results in uncompilable GLR parsers
12622 when both %pure-parser and %locations are used. (trivial change)
12624 2003-04-17 Paul Eggert <eggert@twinsun.com>
12626 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
12627 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
12628 Do not insert the expected token via unput, as this runs afoul
12629 of a POSIX-compatibility bug in flex 2.5.31.
12630 All uses changed to BEGIN the parent state,
12631 since we no longer insert the expected token via unput.
12632 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
12633 that is no longer emitted after the above change.
12635 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
12636 the first one. This change is from Paul Hilfinger, and it fixes
12637 regression reported by Werner Lemberg in
12638 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
12640 (resolve_sr_conflict): Don't invoke state_errs_set
12641 unless one or more tokens have been explicitly made errors.
12642 Otherwise, the above change causes Bison to abort.
12644 * tests/existing.at (GNU pic Grammar): New test case, taken from
12647 2003-03-31 Akim Demaille <akim@epita.fr>
12649 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
12651 2003-03-31 Akim Demaille <akim@epita.fr>
12653 * src/output.c (prepare_symbols): Avoid trailing spaces in the
12656 2003-03-31 Akim Demaille <akim@epita.fr>
12658 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
12659 From Paul Hilfinger.
12661 2003-03-29 Akim Demaille <akim@epita.fr>
12663 * m4/error.m4: Do not put under dynamic conditions some code which
12664 expansion is under static control.
12666 2003-03-29 Akim Demaille <akim@epita.fr>
12668 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
12670 2003-03-29 Akim Demaille <akim@epita.fr>
12672 * doc/bison.texinfo (Strings are Destroyed): New.
12674 2003-03-13 Paul Eggert <eggert@twinsun.com>
12676 * .cvsignore: Add configure.lineno.
12677 * src/.cvsignore: Add yacc.
12678 * tests/.cvsignore: Add testsuite.log.
12679 * doc/fdl.texi: Sync with latest FSF version.
12681 2003-03-12 Paul Eggert <eggert@twinsun.com>
12683 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
12684 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
12685 cursor, instead of leaving it undefined. This fixes a bug
12686 reported by Tim Van Holder in
12687 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
12688 * tests/input.at (Torturing the Scanner): Test the scanner on
12689 an empty input file, which was Tim Van Holder's test case.
12691 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
12692 <sys/resource.h> can be included, include sys/time.h and
12693 sys/times.h first, if available. This works around the SunOS
12694 4.1.4 porting bug reported by Bruce Becker in
12695 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
12697 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
12698 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
12699 AC_HEADER_SYS_WAIT.
12701 Merge changes from gnulib. This was prompted because the CVS
12702 snapshot didn't build on Solaris 7 due to strnlen problems.
12704 These changes need to be merged back into gnulib:
12705 * lib/hash.c: Include <stdbool.h> unconditionally.
12706 * m4/onceonly.m4 (m4_quote): New macro.
12707 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
12708 Quote AC_FOREACH variable-expansions properly.
12709 The 2003-01-03 obstack.h change also needs merging.
12710 {end of changes requiring merging}
12712 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
12713 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

12717 New files, imported from gnulib.
12718 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
12721 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
12722 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current

12731 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
12732 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
12733 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
12734 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
12735 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
12736 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
12737 (jm_PREREQ_ARGMATCH): Remove.
12738 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
12739 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
12741 * src/system.h: Include <stdbool.h> unconditionally.
12743 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
12744 assuming at least C89 in the bitset code for some time now.
12746 2003-03-03 Akim Demaille <akim@epita.fr>
12750 2003-03-02 Akim Demaille <akim@epita.fr>
12752 * doc/bison.texinfo (Table of Symbols): Reactivate the
12753 documentation for %lex-param, and %parse-param.
12755 2003-03-02 Akim Demaille <akim@epita.fr>
12757 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
12758 generate verbose error messages.
12759 Use the number of tokens as an upper bound in yytname, as it
12760 cannot be a non terminal.
12762 2003-03-02 Akim Demaille <akim@epita.fr>
12764 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
12767 2003-03-02 Akim Demaille <akim@epita.fr>
12769 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
12770 Use them to exercise yycheck overrun.
12771 Based on Andrew Suffield's grammar.
12773 2003-03-02 Akim Demaille <akim@epita.fr>
12775 Create tests/local.at for Bison generic testing macros.
12777 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...

12781 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
12782 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
12783 * tests/local.at: here.
12784 (AT_COMPILE_CXX): Tags the tests using it as c++.
12785 Ignore the test if CXX is not functional.
12787 2003-03-01 Paul Eggert <eggert@twinsun.com>
12789 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12790 not loc->end, since loc->end might contain garbage and this leads
12791 to undefined behavior on some platforms.
12792 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12793 depend on *loc, so that the reader doesn't give the the false
12794 impression that *loc is initialized.
12795 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12796 does not survive the return.
12798 2003-03-01 Akim Demaille <akim@epita.fr>
12800 * src/scan-gram.l (code_start): Always initialize it when entering
12801 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12802 yylex invocation. An alternative would be making it static, but
12803 then it starts with the second %%'s beginning, instead of its end.
12805 2003-02-28 Paul Eggert <eggert@twinsun.com>
12807 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12808 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12809 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12811 2003-02-26 Paul Eggert <eggert@twinsun.com>
12813 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12814 Remove Sequent/Pyramid discussion (nobody uses them any more).
12815 Merge VMS and MS-DOS discussion; these ports may well be dead
12816 but let's keep mentioning them for now. Put <> around email
12817 addresses. Add copyright notice.
12819 2003-02-24 Paul Eggert <eggert@twinsun.com>
12821 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12822 to avoid collision with flex use of yylineno.

12833 change integer types.
12834 Suggested by Paul Eggert.
12836 2003-02-21 Akim Demaille <akim@epita.fr>
12838 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12839 to avoid confusions with lalr1.cc's notion of Position.
12840 Suggested by Paul Eggert.
12842 2003-02-20 Akim Demaille <akim@epita.fr>
12844 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12845 before initial_columns.
12846 (location.hh): Use consistent variable names when defining the
12848 Use "last" so that we subtract from Positions, not from unsigned.
12850 2003-02-20 Akim Demaille <akim@epita.fr>
12852 * data/lalr1.cc (position.hh): New subfile, including the extended
12853 and Doxygen'ed documentation of class Position.
12854 (location.hh): Use it.
12855 Document a` la Doxygen.
12856 With the help of Benoit Perrot.

12865 Don't use the location in yy::Parser::error_ and
12866 yy::Parser::print_ when not %locations.
12867 Activate more lalr1.cc tests.
12869 2003-02-19 Akim Demaille <akim@epita.fr>
12871 * data/lalr1.cc: When displaying a line number, be sure to make it
12874 2003-02-19 Akim Demaille <akim@epita.fr>
12876 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12878 (YYABORT, YYACCEPT, YYERROR): New.
12879 * tests/calc.at: Renable the lalr1.cc test.
12881 2003-02-19 Akim Demaille <akim@epita.fr>
12883 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12884 error recovery, mixing with/without pops and discarding of the
12887 Disable the lalr1.cc tests as currently it doesn't support YYERROR.

12901 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12902 Check for malloc failure, for consistency with yacc.c.
12903 (yytname_size): Remove, for consistency with yacc.c.
12905 The bug still remains in data/lalr1.cc, as I didn't have time
12908 2003-02-06 Akim Demaille <akim@epita.fr>

13058 * data/lalr1.cc: Do not use @output_header_name@ unless
13059 b4_defines_flag is set. This fixes two bugs reported by
13061 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
13062 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
13064 2003-01-21 Paul Eggert <eggert@twinsun.com>
13066 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
13067 we don't need to worry about yyerrlab1 being reported as an
13068 "unused label" by non-GCC C compilers. The downside is that if
13069 locations are used then a couple of statements are duplicated each
13070 time YYERROR is invoked, but the upside is that the warnings
13072 (yyerrlab1): Move code to YERROR.
13073 (yyerrlab2): Remove. Change uses back to yyerrlab1.
13074 This reverts some of the 2002-12-27 change.
13076 2003-01-17 Paul Eggert <eggert@twinsun.com>
13078 * src/output.c (symbol_printers_output): Fix typo that led
13079 to core dump. Problem reported by Antonio Rus in
13080 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
13082 2003-01-13 Akim Demaille <akim@epita.fr>,
13083 Quoc Peyrot <chojin@lrde.epita.fr>,
13084 Robert Anisko <anisko_r@lrde.epita.fr>
13086 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
13087 when the stacks contain one element, as the loop would otherwise
13088 free the last state, and then use the top state (the one we just
13089 popped). This means that the initial elements will not be freed
13090 explicitly, as is the case in yacc.c; it is not a problem, as
13091 these elements have fake values.
13093 2003-01-11 Paul Eggert <eggert@twinsun.com>
13095 * NEWS: %expect-violations are now just warnings, reverting
13096 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
13097 bootstrapping problem reported by Matthias Klose; see
13098 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
13099 * src/conflicts.c (conflicts_print): Likewise.
13100 * tests/conflicts.at (%expect not enough, %expect too much,
13101 %expect with reduce conflicts): Likewise.
13102 * doc/bison.texinfo (Expect Decl): Document this. Also mention
13103 that the warning is enabled if the number of conflicts changes
13104 (not necessarily increases).
13106 * src/getargs.c (version): Update copyright year.
13108 2003-01-09 Akim Demaille <akim@epita.fr>
13110 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
13112 2003-01-08 Paul Eggert <eggert@twinsun.com>
13114 * Makefile.maint (WGETFLAGS):
13115 New macro, containing "-C off" to disable proxy caches.
13116 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
13117 (rel-check): Use $(WGET) instead of wget.
13119 2003-01-06 Paul Eggert <eggert@twinsun.com>
13121 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
13122 the GLR paper of Scott, Johnstone and Hussain.
13124 2003-01-04 Paul Eggert <eggert@twinsun.com>
13126 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
13127 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
13128 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
13129 (EXTRA_LIBRARIES): New var, for liby.a.
13130 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
13131 (EXTRA_SCRIPTS): New var, for yacc.
13133 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
13134 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
13135 Problem reported by Nelson H. F. Beebe.
13137 2003-01-03 Paul Eggert <eggert@twinsun.com>
13139 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
13140 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
13141 when compiling Bison 1.875's `bitset bset = obstack_alloc
13142 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
13144 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
13145 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
13146 grow to a huge size with typical invocation.
13148 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
13149 Use the pattern recommended by Autoconf 2.57, except also protect
13150 against double-definition.
13151 * src/system.h: Likewise.
13152 Portability issues reported by Nelson H. F. Beebe.
13154 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
13155 All uses changed. Provide a definition in both C and C++.
13156 (yytrue, yyfalse): Define even if defined (__cplusplus).
13158 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
13159 Reported by Nelson H. F. Beebe.
13161 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
13163 2003-01-02 Paul Eggert <eggert@twinsun.com>
13165 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
13166 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
13167 Bug reported by Nelson H. F. Beebe.
13169 2003-01-01 Paul Eggert <eggert@twinsun.com>
13173 2002-12-30 Paul Eggert <eggert@twinsun.com>
13175 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
13177 (<INITIAL>","): Here. This causes stray "," to be treated
13180 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
13181 last brace in braced code when not in Yacc mode, for compatibility
13182 with Bison 1.35. This resurrects the 2001-12-15 patch to
13185 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
13186 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
13188 2002-12-28 Paul Eggert <eggert@twinsun.com>
13190 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
13191 that of SYM's type. This fixes Debian bug 168069, reported by
13194 2002-12-28 Paul Eggert <eggert@twinsun.com>
13198 Switch back to the Yacc style of conflict reports, undoing some
13199 of the 2002-07-30 change.
13200 * doc/bison.texinfo (Understanding): Use Yacc style for
13201 conflict reports. Also, use new way of locating rules.
13202 * src/conflicts.c (conflict_report):
13203 Renamed from conflict_report_yacc, removing the old
13204 'conflict_report'. Translate the entire conflict report at once,
13205 so that we don't assume that "," has the same interpretation in
13207 (conflicts_output): Use Yacc-style conflict report for each state,
13208 instead of our more-complicated style.
13209 (conflicts_print): Use Yacc-style conflict report, except print
13210 the input file name when not emulating Yacc.
13211 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
13212 Conflicted Reduction, %expect not enough, %expect too much,
13213 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
13214 * tests/existing.at (GNU Cim Grammar): Likewise.
13215 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
13217 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
13218 fatal): Don't invoke fflush; it's not needed and it might even be
13219 harmful for stdout, as stdout might not be open.
13220 * src/reduce.c (reduce_print): Likewise.
13222 2002-12-27 Paul Eggert <eggert@twinsun.com>
13224 Fix a bug where error locations were not being recorded correctly.
13225 This problem was originally reported by Paul Hilfinger in
13226 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
13228 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13229 top of the location stack's error locations.
13230 (yyerrlab): Set it. When discarding a token, push its location
13231 onto yylerrsp so that we don't lose track of the error's end.
13232 (yyerrlab1): Now is only the target of YYERROR, so that we can
13233 properly record the location of the action that failed. For GCC
13234 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13235 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13236 (yyerrlab2): New label, which yyerrlab now falls through to.
13237 Compute the error's location by applying YYLLOC_DEFAULT to
13238 the locations of all the symbols that went into the error.
13239 * doc/bison.texinfo (Location Default Action): Mention that
13240 YYLLOC_DEFAULT is also invoked for syntax errors.
13241 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13242 Error locations include the locations of all the tokens that were
13243 discarded, not just the last token.
13245 2002-12-26 Paul Eggert <eggert@twinsun.com>
13247 * src/files.c: Include quote.h.
13248 (compute_output_file_names): Warn if we detect conflicting
13249 outputs to the same file. This should catch the misunderstanding
13250 exemplified by Debian Bug 165349, reported by Bruce Stephens..
13252 * src/conflicts.c (conflicts_print): If the user specifies
13253 "%expect N", report an error if there are any reduce/reduce
13254 conflicts. This is what the manual says should happen.
13255 This fixes Debian bug 130890, reported by Anthony DeRobertis.
13256 * tests/conflicts.at (%expect with reduce conflicts): New test.
13258 Don't use m4_include on relative file names, as it doesn't work as
13259 desired if there happens to be a file with that name under ".".
13261 * m4sugar/version.m4: Remove; it was included but it wasn't used.
13262 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
13263 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
13264 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
13265 * src/output.c (output_skeleton): Use full path names when
13266 specifying a file to include; don't rely on include path, as
13267 it's unreliable when the working file contains a file with
13270 2002-12-25 Paul Eggert <eggert@twinsun.com>
13272 Remove obsolete references to bison.simple and bison.hairy.
13273 Problem mentioned by Aubin Mahe in
13274 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
13275 * data/glr.c: Comment fix.
13276 * doc/bison.1: Remove references. Also, mention "yacc".
13278 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
13281 * src/parse-gram.y (declaration): Use enum "report_states" rather
13282 than its numeric value 1.
13284 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
13285 opening a new one. This fixes Debian bug 165349, reported by
13288 2002-12-24 Paul Eggert <eggert@twinsun.com>
13292 * Makefile.maint (cvs-update): Don't assume that the shell
13293 supports $(...), as Solaris sh doesn't.
13295 * src/parse-gram.y (lloc_default): Remove test for empty
13296 nonterminals at the end, since it didn't change the result.
13298 2002-12-24 Paul Eggert <eggert@twinsun.com>
13300 If the user does not define YYSTYPE as a macro, Bison now declares it
13301 using typedef instead of defining it as a macro. POSIX requires this.
13302 For consistency, YYLTYPE is also declared instead of defined.
13304 %union directives can now have a tag before the `{', e.g., the
13305 directive `%union foo {...}' now generates the C code
13306 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13307 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13308 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13309 instead of `yyltype'.
13311 `yystype' and `yyltype' are now obsolescent macros instead of being
13312 typedefs or tags; they are no longer documented and will be
13313 withdrawn in a future release.
13315 * data/glr.c (b4_location_type): Remove.
13316 (YYSTYPE): Renamed from yystype.
13317 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
13318 (struct YYLTYPE): Renamed from struct yyltype.
13319 (YYLTYPE): Renamed from yyltype.
13320 (yyltype, yystype): New (and obsolescent) macros,
13321 for backward compatibility.
13322 * data/yacc.c: Likewise.
13324 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13325 does not specify a union tag. This is for compatibility with
13328 * src/parse-gram.y (add_param): 2nd arg is now char * not char
13329 const *, since it is now modified by stripping surrounding { }.
13330 (current_braced_code): Remove.
13331 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
13332 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
13333 trailing " {...}". Now of type <chars>.
13334 (grammar_declaration): Adjust to bundled tokens.
13335 (code_content): Remove; stripping is now done by add_param.
13336 (print_token_value): Print contents of bundled tokens.
13337 (token_name): New function.
13339 * src/reader.h (braced_code, current_braced_code): Remove.
13340 (token_name): New decl.
13342 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
13343 token_type, not braced_code code_kind. All uses changed.
13344 (SC_PRE_CODE): New state, for scanning after a keyword that
13345 has (or usually has) an immediately-following braced code.
13346 (token_type): New local var, to keep track of which token type
13347 to return when scanning braced code.
13348 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
13349 <INITIAL>"%parse-param", <INITIAL>"%printer",
13350 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
13351 instead of returning a token type immediately.
13352 (<INITIAL>"{"): Set token type.
13353 (<SC_BRACED_CODE>"}"): Use it.
13354 (handle_action_dollar, handle_action_at): Now returns bool
13355 indicating success. Fail if ! current_rule; this prevents a core dump.
13356 (handle_symbol_code_dollar, handle_symbol_code_at):
13357 Remove; merge body into caller.
13358 (handle_dollar, handle_at): Complain in invalid contexts.
13360 * NEWS, doc/bison.texinfo: Document the above.
13361 * NEWS: Fix years and program names in copyright notice.
13363 2002-12-17 Paul Eggert <eggert@twinsun.com>
13365 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
13366 Reporting, Table of Symbols): Omit mentions of %lex-param and
13367 %parse-param from the documentation for now.
13369 2002-12-15 Paul Eggert <eggert@twinsun.com>
13371 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
13372 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
13373 lookahead symbol, and which sets yychar in parser actions) and it
13374 disagreed with the Bison documentation. Bug
13375 reported by Andrew Walrond.
13377 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
13378 as the caller now does that.
13379 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
13380 (YYEMPTY): Parenthesize right hand side, since others use it.
13381 (yyparse): Don't assume that our generated code is the only code
13384 2002-12-13 Paul Eggert <eggert@twinsun.com>
13388 POSIX requires a "yacc" command.
13389 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
13390 (MOSTLYCLEANFILES): Add yacc.
13392 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
13393 as an alias for bison y.
13395 * po/LINGUAS: Add da.
13397 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
13398 problem with latest <getopt.h>.
13399 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
13401 * doc/fdl.texi: Upgrade to 1.2.
13402 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
13403 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
13404 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
13406 * config/install-sh: Sync with autotools.
13408 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
13409 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13410 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
13411 locations are requested.
13412 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
13413 locations are requested.
13415 2002-12-12 Paul Eggert <eggert@twinsun.com>
13417 Remove unportable casts and storage allocation tricks.
13418 While we're at it, remove almost all casts, since they
13419 usually aren't needed and are a sign of trouble.
13421 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13423 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13424 the pointer DSET returned by malloc; this isn't portable.
13425 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13426 Similarly for DERIVES.
13427 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
13428 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
13429 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
13431 * src/derives.c (derives_compute): Do not bother invoking
13432 int_of_rule_number, since rule numbers are integers.
13434 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
13435 rather than XMALLOC (char, N).
13437 * src/files.c (filename_split): Rewrite to avoid cast.
13439 * src/gram.h (symbol_number_as_item_number,
13440 item_number_as_symbol_number, rule_number_as_item_number,
13441 item_number_as_rule_number):
13442 Now inline functions rather than macros, to avoid casts.
13443 * src/state.h (state_number_as_int): Likewise.
13444 * src/tables.c (state_number_to_vector_number,
13445 symbol_number_to_vector_number): Likewise.
13447 * src/gram.h (int_of_rule_number): Remove; no longer used.
13449 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
13450 since the resulting storage is always stored into.
13452 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
13455 * src/muscle_tab.c (muscle_m4_output):
13456 Now inline. Return bool, not int.
13457 * src/state.c (state_compare): Likewise.
13458 * src/symtab.c (symbol_check_defined,
13459 symbol_check_alias_consistency, symbol_pack, symbol_translation,
13460 hash_compare_symbol, hash_symbol):
13462 * src/uniqstr.c (uniqstr_print): Likewise.
13463 * src/muscle_tab.c (muscle_m4_output_processor):
13464 New function, to avoid casts.
13465 * src/state.c (state_comparator, stage_hasher): Likewise.
13466 * src/symtab.c (symbol_check_defined_processor,
13467 symbol_check_alias_consistency_processor, symbol_pack_processor,
13468 symbol_translation_processor, hash_symbol_comparator,
13469 hash_symbol_hasher): Likewise.
13470 * src/uniqstr.c (uniqstr_print_processor): Likewise.
13471 * src/muscle_tab.c (muscles_m4_output):
13472 Use new functions instead of casting old functions unportably.
13473 * src/state.c (state_hash_new): Likewise.
13474 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
13475 symbols_token_translations_init):
13477 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
13479 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13480 var instead of casting to long, to avoid casts.
13481 (prepare_states): Use MALLOC rather than alloca, so that we don't
13482 have to worry about alloca.
13483 * src/state.c (state_hash_lookup): Likewise.
13485 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
13486 local var instead of casting to unsigned char, to avoid casts.
13488 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
13489 STATE_ALLOC): Remove.
13490 (transitions_new, errs_new, reductions_new, state_new): Use malloc
13491 rather than calloc, and use offsetof to avoid allocating slightly
13493 (state_new): Initialize all members.
13495 * src/state.c (state_hash): Use unsigned accumulator, not signed.
13497 * src/symtab.c (symbol_free): Remove; unused.
13498 (symbol_get): Remove cast in lhs of assignment.
13499 (symbols_do): Now static. Accept generic arguments, not
13500 hashing-related ones.
13502 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
13503 (symbol_processor): Remove.
13504 (symbols_do): Remove decl; now static.
13506 * src/system.h (alloca): Remove; decl no longer needed.
13507 (<stddef.h>): Include, for offsetof.
13508 (<inttypes.>, <stdint.h>): Include if available.
13509 (uintptr_t): New type, if system lacks it.
13510 (CALLOC, MALLOC, REALLOC): New macros.
13511 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
13514 * src/tables.c (table_size): Now int, to pacify GCC.
13515 (table_grow, table_ninf_remap): Use signed table size.
13516 (save_row): Don't bother initializing locals when not needed.

13527 2002-12-09 Paul Eggert <eggert@twinsun.com>
13529 Change identifier spellings to avoid collisions with names
13530 that are reserved by POSIX.
13532 Don't use names ending in _t, since POSIX reserves them.
13533 For consistency, remove _e and _s endings -- they're weren't
13534 needed to remove ambiguity. All uses changed.
13535 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
13536 turn was just renamed from struniq_t.
13537 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
13538 which in turn was just renamed from struniq_processor_t.
13539 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
13540 in turn was renamed from hash_compare_struniq_t.

13609 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
13610 value_t_as_yystype -> value_as_yystype.
13612 Don't include <errno.h> in the mainstream code, since it
13613 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
13614 * lib/get-errno.c, lib/get-errno.h: New files.
13615 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
13617 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
13618 * src/output.c (output_skeleton): Likewise.

13624 * src/system.h: Do not include <errno.h>.
13625 (TAB_EXT): Renamed from EXT_TAB.
13626 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
13628 Avoid str[a-z]*, since <string.h> reserves that name space.
13629 Change all instances of "struniq" in names to "uniqstr", and
13630 likewise for "STRUNIQ" and "UNIQSTR".
13631 * src/uniqstr.c: Renamed from src/struniq.c.
13632 * src/uniqstr.h: Renamed from src/struniq.h.
13633 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
13634 * src/files.c (strsuffix): Remove; unused.
13635 (concat2): Renamed from stringappend. Now static.
13636 * src/files.h (strsuffix, stringappend): Remove; unused.
13637 * src/parse-gram.y (<chars>): Renamed from <string>.

13643 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
13644 (N_EXPAND): Renamed from N_STRETCH.

13647 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
13648 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
13650 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.
13651 * src/state.h (STATE_NUMBER_MAXIMUM): Renamed from STATE_NUMBER_MAX.
13652 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.

13654 (BASE_MAXIMUM): Renamed from BASE_MAX.
13655 (BASE_MINIMUM): Renamed from BASE_MIN.
13656 (ACTION_MAX): Remove; unused.
13657 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
13658 Unnecessary casts removed from above defines.
13661 Fix misspelling in names.
13662 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
13663 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
13667 * lib/timevar.c (timevar_report): Renamed from time_report,
13668 for consistency with other names.
13669 * lib/timevar.h (timevar_report): New decl.
13670 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
13673 Sort include-file uses.
13675 Reorder all include files under src to be in the order "system.h".
13676 then the ../lib include files in angle brackets (alphabetized),
13677 then the . include files in double-quotes (alphabetized). Fix
13678 dependency breakages encountered in this process, as follows:
13679 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
13680 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
13681 * src/state.h: Include "symtab.h".
13683 2002-12-08 Paul Eggert <eggert@twinsun.com>
13685 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
13686 since this causes problems when __file__ contains character
13687 sequences like "@" that are treated specially by src/scan-skel.l.
13688 Instead, just use the file's basename. This fixes the bug
13689 reported by Martin Mokrejs in
13690 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
13692 2002-12-06 Paul Eggert <eggert@twinsun.com>
13694 Add support for rules that do not have trailing semicolons, as
13695 POSIX requires. Improve the quality of locations in Bison
13698 * src/location.c: Include <quotearg.h>.
13699 (empty_location): Now const.
13700 (location_print): New function. Follow the recommendation of the
13701 GNU Coding Standards for locations that span file boundaries.
13702 * src/location.h: Do not include <quotearg.h>; no longer needed.
13703 (boundary): New type.
13704 (location_t): Use it. This allows locations to span file boundaries.
13705 All member uses changed: file -> start.file or end.file (as needed),
13706 first_line -> start.line, first_column -> start.column,
13707 last_line -> end.line, last_column -> end.column.
13708 (equal_boundaries): New function.
13709 (LOCATION_RESET, LOCATION_STEP): Remove.
13710 (LOCATION_PRINT): Remove. All callers changed to use location_print.
13711 (empty_location): Now const.
13712 (location_print): New decl.
13713 * src/parse-gram.y (lloc_default): New function, which handles
13714 empty locations more accurately.
13715 (YYLLOC_DEFAULT): Use it.
13716 (%token COLON): Remove.
13717 (%token ID_COLON): New token.
13719 (declarations, rules): Remove trailing semicolon.
13720 (declaration, rules_or_grammar_declaration):
13721 Allow empty (";") declaration.
13722 (symbol_def): Remove empty actions; no longer needed.
13723 (rules_or_grammar_declaration): Remove trailing semicolon.
13724 (semi_colon.opt): Remove.
13725 * src/reader.h: Include location.h.
13726 (scanner_cursor): New decl.
13727 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
13729 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
13731 (STEP): Remove. No longer needed, now that adjust_location does
13732 the work. All uses removed.
13733 (scanner_cursor): New var.
13734 (adjust_location): Renamed from extend_location. It now sets
13735 *loc and adjusts the scanner cursor. All uses changed.
13736 Don't bother testing for CR.
13737 (handle_syncline): Remove location arg; now updates scanner cursor.
13738 All callers changed.
13739 (unexpected_end_of_file): Now accepts start boundary of token or
13740 comment, not location. All callers changed. Update scanner cursor,
13742 (SC_AFTER_IDENTIFIER): New state.
13743 (context_state): Renamed from c_context. All uses changed.
13744 (id_loc, code_start, token_start): New local vars.
13745 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
13746 processing of Yacc white space and equivalents here.
13747 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
13748 instead of returning ID immediately, since we need to search for
13749 a subsequent colon.
13750 (<INITIAL>"'", "\""): Save token_start.
13751 (<INITIAL>"%{", "{", "%%"): Save code_start.
13752 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
13753 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
13754 BEGIN context_state at end, not INITIAL.
13755 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
13756 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
13757 Return correct token start.
13758 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
13759 the start of a character, string or multiline comment is found.
13760 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
13761 Reduction): Adjust reported locations to match the more-precise
13762 results now expected.
13763 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
13764 * tests/reduce.at (Useless Rules, Reduced Automaton,
13765 Underivable Rules): Likewise.
13766 * tests/regression.at (Invalid inputs): No longer `expecting ";"
13767 or "|"' now that so many other tokens are allowed by the new grammar.
13769 * src/complain.h (current_file): Remove duplicate decl;
13770 current_file is now owned by files.h.
13771 * src/complain.c, src/scan-gram.l: Include files.h.
13773 2002-12-06 Paul Eggert <eggert@twinsun.com>
13775 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
13776 promotes to int; it might be unsigned int.
13777 * data/yacc.c (yy_reduce_print): Likewise.
13779 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
13780 be #defined in the prologue, not in the Bison declarations.
13781 This fixes Debian Bug 102878, reported by Shaul Karl.
13783 2002-12-02 Paul Eggert <eggert@twinsun.com>
13785 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
13786 * lib/strtoul.c: New file, from gnulib.
13787 This fixes a porting bug reported by Peter Klein in
13788 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13790 2002-11-30 Paul Eggert <eggert@twinsun.com>
13792 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13793 and put only a forward declaration in the prologue. This is for
13794 consistency with the other scanner helper functions.
13796 Type clashes now generate warnings, not errors, since it
13797 appears that POSIX may allow some grammars with type clashes.
13798 * src/reader.c (grammar_current_rule_check): Warn about
13799 type clashes instead of complaining.
13800 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13802 Add Yacc library, since POSIX requires it.
13803 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13804 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13805 * lib/main.c, lib/yyerror.c: New files.
13807 gram_error can be static; it need not be extern.
13808 * src/reader.h (gram_error): Remove decl.
13809 * src/parse-gram.y (gram_error): Now static. Add static decl.
13810 (print_token_value): Omit parameter names from forward decl,
13813 2002-11-29 Paul Eggert <eggert@twinsun.com>
13815 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13816 be declared before being used. E.g., one should typically
13817 declare them in the prologue. Use GNU coding style in examples.
13818 Put "const" consistently after the type it modifies. Mention
13819 that C99 supports "inline". Mention that yyerror traditionally
13822 %parse-param and %lex-param now take just one argument, the
13823 declaration; the argument name is deduced from the declaration.
13825 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13826 Reporting, Table of Symbols): Document this.
13827 * src/parse-gram.y (add_param): New function.
13829 (declaration): Implement new rule for %parse-param and %lex-param.
13830 * src/scan-gram.l: "," now elicits a warning, rather than being
13831 a token; this is more compatible with byacc.
13832 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13834 2002-11-27 Paul Eggert <eggert@twinsun.com>
13836 Rename identifiers to avoid real and potential collisions.
13838 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13839 to avoid collision with lex macro described by Bruce Lilly in
13840 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13841 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13842 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13843 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13845 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13846 The name "yycontrol" violates the name space rules, and this stuff
13847 wasn't being used anyway.
13848 (input): Remove action; this stuff wasn't being used.
13849 (gram_error): Rename local variable yylloc -> loc.
13850 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13851 (YY_DECL): Don't use "yy" at start of local variables.
13852 All uses changed, e.g., yylloc -> loc.
13853 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
13854 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
13855 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
13856 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
13858 * src/parse-gram.y (gram_error): loc is now const *.
13859 * src/reader.h (gram_error): Likewise.
13861 2002-11-24 Paul Eggert <eggert@twinsun.com>
13865 * tests/actions.at (Actions after errors): Use an output format
13866 more similar to that of the Printers and Destructors test.
13867 Test the position of the ';' token too.
13868 (Printers and Destructors): Likewise.
13869 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13870 unnecessarily alarming people when the test fails.
13872 * data/yacc.c (yyerrlab1): Move this label down, so that the
13873 parser does not discard the lookahead token if the user code
13874 invokes YYERROR. This change is required for POSIX conformance.
13876 * lib/error.c: Sync with gnulib.
13878 2002-11-22 Paul Eggert <eggert@twinsun.com>
13880 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
13881 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
13882 * lib/xmalloc.c: Likewise.
13884 2002-11-20 Paul Eggert <eggert@twinsun.com>
13886 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13888 2002-11-20 Paul Eggert <eggert@twinsun.com>
13890 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13891 should use `if (! x) abort ();' rather than `assert (x);', and
13892 anyway it's one less thing to worry about configuring.
13894 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13895 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13896 and replace all instances of assert with abort.
13897 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
13898 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
13900 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
13901 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
13902 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
13903 hash_find_entry, hash_rehash, hash_insert): Likewise.
13904 * src/conflicts.c (resolve_sr_conflict): Likewise.
13905 * src/lalr.c (set_goto_map, map_goto): Likewise.
13906 * src/nullable.c (nullable_compute): Likewise.
13907 * src/output.c (prepare_rules, token_definitions_output): Likewise.
13908 * src/reader.c (packgram, reader): Likewise.
13909 * src/state.c (state_new, state_free, state_transitions_set,
13910 state_reduction_find): Likewise.
13911 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
13912 symbol_pack): Likewise.
13913 * src/tables.c (conflict_row, pack_vector): Likewise.
13914 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13915 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13916 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
13917 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
13919 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
13920 (ARGMATCH_CONSTRAINT): New macro.
13921 (ARGMATCH_ASSERT): Use it.
13923 * src/system.h (verify): New macro.
13924 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
13925 rather than assert.
13926 * src/tables.c (tables_generate): Likewise.
13928 * src/struniq.c (struniq_assert): Now returns void, and aborts
13929 if the assertion is false.
13930 (struniq_assert_p): Remove.
13931 * src/struniq.h: Likewise.
13933 2002-11-18 Paul Eggert <eggert@twinsun.com>
13935 * data/glr.c (yygetLRActions): Replace `yyindex' with
13936 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
13937 This fixes the regression with Sun ONE Studio 7 cc that I reported in
13938 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
13940 2002-11-18 Akim Demaille <akim@epita.fr>
13942 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
13944 From Tim Van Holder.
13946 2002-11-17 Paul Eggert <eggert@twinsun.com>
13948 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
13949 to "SyntaxError" for consistency with my 2002-11-15 change.
13951 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
13952 not define to {}, since this breaks the common use of `YYDPRINTF
13953 ((...));' if a single statement is desired (e.g. before `else').
13954 Work around GCC warnings by surrounding corresponding calls with
13956 (yyhasResolvedValue): Remove unused function.
13957 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
13959 (yyreportSyntaxError): Renamed from yyreportParseError.
13960 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
13962 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
13963 extern when possible. Remove unused initializations.
13965 2002-11-16 Akim Demaille <akim@epita.fr>
13967 Augment the similarity between GLR and LALR traces.
13969 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
13970 (YY_REDUCE_PRINT): New.
13971 (yyparse): Use them.
13972 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
13974 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
13975 state reached after the reduction/recovery, since...
13976 (yyparse, yyprocessOneStack): Report the state we are entering in.
13978 2002-11-16 Akim Demaille <akim@epita.fr>
13980 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
13981 Add support for --trace=skeleton.
13982 * src/scan-skel.l: %option debug.
13983 Scan strings of non-@ or \n instead of character by character.
13984 (scan_skel): Handle trace_skeleton.
13986 (@output_parser_name@, @output_header_name@): ``Restore'' their
13987 support (used to be M4 macros).
13988 * data/yacc.c: Quote larger chunks, a la glr.c.
13989 * data/lalr1.cc: Likewise.
13990 The header guards are no longer available, so use some other
13991 string than `YYLSP_NEEDED'.
13993 2002-11-16 Akim Demaille <akim@epita.fr>
13995 Make the ``Printers and Destructors'' test more verbose, taking
13996 `yacc.c''s behavior as (possibly wrong) reference.
13998 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
13999 instead of fprint on stdout.
14000 Set and report the last_line of the symbols.
14001 Consistently display values and locations.
14003 2002-11-16 Paul Eggert <eggert@twinsun.com>
14005 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
14007 2002-11-15 Paul Eggert <eggert@twinsun.com>
14009 * tests/actions.at (Actions after errors): New test case.
14011 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
14012 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
14013 tests/action.at, tests/calc.at, tests/conflicts.at,
14014 tests/cxx-type.at, tests/regression.at:
14015 "parse error" -> "syntax error" for POSIX compatibility.
14016 "parsing stack overflow..." -> "parser stack overflow" so
14017 that code matches Bison documentation.
14019 2002-11-15 Akim Demaille <akim@epita.fr>
14021 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
14022 take two BRACED_CODE, not two string_content.
14023 Free the scanner's obstack when we are done.
14024 (code_content): New.
14025 * tests/calc.at: Adjust.
14026 * doc/bison.texinfo: Adjust.
14027 Also, make sure to include the `,' for these declarations.
14029 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
14031 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
14032 definition; avoids potential autoreconf problems.
14034 2002-11-15 Akim Demaille <akim@epita.fr>
14036 Always check the value returned by yyparse.
14038 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
14039 returned by yyparse.
14040 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
14042 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
14043 returned by yyparse.
14045 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14047 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
14050 2002-11-14 Paul Eggert <eggert@twinsun.com>
14052 * src/output.c (output_skeleton): Call xfopen instead of
14053 duplicating xfopen's body.
14055 Fix bugs reported by Nelson H. F. Beebe in
14056 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
14058 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
14059 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
14060 Group compiler. Instead, use "$CC -E bar.c". Include the .h
14061 file twice in the grammar, as an extra check.
14063 * tests/input.at (Torturing the Scanner): Surround the
14064 backslash-newline tests with "#if 0", to make it less likely that
14065 we'll run into compiler bugs. Bring back solitary \ inside
14066 comment, but add a closing comment to work around HP C bug. Don't
14067 test backslash-newline in C character constant.
14069 2002-11-14 Akim Demaille <akim@epita.fr>
14071 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
14072 status of the compiler.
14073 Calling `exit 1' is no longer needed.
14074 Reported by Nelson H. F. Beebe.
14076 2002-11-14 Akim Demaille <akim@epita.fr>
14078 * tests/atlocal.in (CPPFLAGS): We have config.h.
14079 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
14081 * tests/actions.at, tests/calc.at, tests/conflicts.at,
14082 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
14083 * tests/regression.at, tests/torture.at: Use them for all the
14084 grammars that are to be compiled.
14085 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
14086 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
14087 * doc/bison.texinfo (GLR Parsers): Document `inline'.
14089 2002-11-14 Akim Demaille <akim@epita.fr>
14091 * doc/bison.texinfo: Various formatting changes (alignments in
14092 samples, additional @group/@end group, GCS in samples.
14093 Use @deffn instead of simple @table to define the directives,
14094 macros, variables etc.
14096 2002-11-13 Paul Eggert <eggert@twinsun.com>
14098 Fix some bugs reported by Albert Chin-A-Young in
14099 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
14101 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
14102 -o c"; the HP C compiler chatters during compilation.
14103 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
14104 * tests/headers.at (export YYLTYPE): Likewise.
14106 * tests/input.at (Torturing the Scanner): Remove lines containing
14107 solitary backslashes, as they tickle a bug in the HP C compiler.
14109 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
14110 comments, since they're not portable. Use GNU coding style.
14112 2002-11-13 Akim Demaille <akim@epita.fr>
14114 * data/yacc.c: Leave bigger chunks of quoted text.
14115 (YYDSYMPRINTF): New.
14116 Use it to report symbol activities.
14117 * data/glr.c (YYDSYMPRINTF): New.
14120 2002-11-12 Paul Eggert <eggert@twinsun.com>
14124 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
14125 (yyglrReduce): Return yyok, not 0.
14126 This should avoid the enumerated-type warnings reported
14127 by Nelson H. F. Beebe in
14128 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
14130 * lib/bbitset.h (BITSET_INLINE): Remove.
14131 * lib/bitset.h [! BITSET_INLINE]: Remove.
14132 (bitset_set, bitset_reset, bitset_test): Rename local vars
14133 to avoid shadowing warnings by GCC.
14135 * data/glr.c (inline): Remove #define. It's the user's
14136 responsibility to #define it away, just like 'const'.
14137 This fixes one of the bugs reported by Nelson H. F. Beebe in
14138 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
14140 * Makefile.maint (po-check): Scan .l and .y files instead of the
14141 .c and the .h files that they generate. This fixes the bug
14142 reported by Tim Van Holder in:
14143 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
14144 Look for N_ as well as for _. Try to avoid matching #define for
14146 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
14147 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
14148 * src/scan-gram.l: Revamp regular expressions so that " and '
14149 do not confuse xgettext.
14151 * src/struniq.h (struniq_new): Do not declare the return type
14152 to be 'const'; this violates the C standard.
14153 * src/struniq.c (struniq_new): Likewise.
14155 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
14157 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
14158 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
14161 2002-11-12 Akim Demaille <akim@epita.fr>
14163 * Makefile.maint: Sync with Autoconf:
14164 (local_updates): New.
14166 2002-11-12 Akim Demaille <akim@epita.fr>
14168 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
14170 2002-11-12 Akim Demaille <akim@epita.fr>
14172 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
14175 2002-11-12 Akim Demaille <akim@epita.fr>
14177 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
14180 2002-11-12 Akim Demaille <akim@epita.fr>
14182 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
14183 Use it to test the GLR parser.
14185 2002-11-12 Akim Demaille <akim@epita.fr>
14187 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
14189 * data/glr.c (yystos): New.
14190 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
14191 (YYDSYMPRINT): New.
14192 (yyval): Don't define it, it is handled via M4.
14193 (yyrecoverParseError): Free verbosely the discarded symbols.
14194 * data/yacc.c (yysymprint): Remove, rather...
14195 (b4_yysymprint_generate): invoke.
14196 * data/c.m4 (b4_yysymprint_generate): New.
14197 Accept pointers as arguments, as opposed to the version from
14199 (b4_yydestruct_generate): Likewise.
14200 * tests/cations.at (Printers and Destructors): Use Bison directives
14201 instead of CPP macros.
14202 Don't rely on internal details.
14204 2002-11-12 Akim Demaille <akim@epita.fr>
14206 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
14207 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
14208 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
14209 it against YYEMPTY and so forth), work on yytoken (i.e., set
14210 it to YYEMPTY etc.).
14211 (yydestruct): Replace with a b4_yydestruct_generate invocation.
14212 (b4_symbol_actions): Remove.
14213 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
14214 for 0, end-of-input.
14216 2002-11-12 Akim Demaille <akim@epita.fr>
14218 * doc/bison.texinfo (Destructor Decl): New.
14220 2002-11-12 Akim Demaille <akim@epita.fr>
14222 * src/tables.c (tables_generate): Use free for pointers that
14223 cannot be NULL, not XFREE.
14224 (pack_vector): Use assert, not fatal, for bound violations.
14225 * src/state.c (state_new): Likewise.
14226 * src/reader.c (reader): Likewise.
14227 * src/lalr.c (set_goto_map): Likewise.
14228 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
14231 2002-11-12 Akim Demaille <akim@epita.fr>
14233 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
14235 * src/scan-gram.l (last_string): Is global to the file, not to
14237 * src/parse-gram.y (input): Don't append the epilogue here,
14238 (epilogue.opt): do it here, and free the scanner's obstack.
14239 * src/reader.c (epilogue_set): Rename as...
14240 (epilogue_augment): this.
14241 * data/c.m4 (b4_epilogue): Defaults to empty.
14243 2002-11-12 Akim Demaille <akim@epita.fr>
14245 * src/getargs.c (long_options): Remove duplicates.
14246 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
14248 * doc/bison.rnh: Remove.
14249 * doc/bison.texinfo (VMS Invocation): Remove.
14251 2002-11-12 Akim Demaille <akim@epita.fr>
14253 * src/struniq.h, src/struniq.c (struniq_t): Is const.
14254 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
14256 Use struniq for symbols.
14258 * src/symtab.h (symbol_t): The tag member is a struniq.
14259 (symbol_type_set): Adjust.
14260 * src/symtab.c (symbol_new): Takes a struniq.
14261 (symbol_free): Don't free the tag member.
14262 (hash_compare_symbol_t, hash_symbol_t): Rename as...
14263 (hash_compare_symbol, hash_symbol): these.
14264 Use the fact that tags as struniqs.
14265 (symbol_get): Use struniq_new.
14266 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
14268 * src/reader.h (merger_list, grammar_currentmerge_set): The name
14269 and type members are struniqs.
14270 * src/reader.c (get_merge_function)
14271 (grammar_current_rule_merge_set): Adjust.
14272 (TYPE, current_type): Are struniq.
14274 Use struniq for file names.
14276 * src/files.h, src/files.c (infile): Split into...
14277 (grammar_file, current_file): these.
14278 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.

14280 * src/getargs.c (getargs): Likewise.
14281 * src/complain.h, src/complain.c: Likewise.
14282 * src/main.c (main): Call struniqs_new early enough to use it for
14284 Don't free the input file name.
14286 2002-11-12 Akim Demaille <akim@epita.fr>
14288 * src/symtab.c (symbol_free): Remove dead deactivated code:

14299 2002-11-11 Paul Eggert <eggert@twinsun.com>
14301 Revamp to fix many (but not all) of the C- and M4-related quoting
14302 problems. Among other things, this fixes the Bison bug reported
14303 by Jan Hubicka when processing the Bash grammar; see:
14304 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
14306 Use new @ escapes consistently. Represent brackets with @{ and @}
14307 rather than @<:@ and @:>@, since this works a bit better with dumb
14308 editors like vi. Represent @ with @@, since @ is now consistently
14309 an escape. Use @oline@ and @ofile@ rather than __oline__ and
14310 __ofile__, to avoid unexpected expansions. Similarly, use @output
14311 rather than #output.
14313 * data/c.m4 (b4_copyright): Omit file name from comment, since
14314 the file name could contain "*/".
14315 (b4_synclines_flag): Don't quote the 2nd argument; it should already
14316 be quoted. All uses changed.
14318 * data/glr.c: Use new @ escapes consistently.
14319 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
14320 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
14321 Remove, since they couldn't handle arbitrary characters in file
14323 * data/lalr1.cc: Likewise.
14324 * data/yacc.c: Likewise.
14326 * src/files.c (output_infix): Remove; all uses removed.
14327 * src/files.h: Likewise.
14329 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
14330 mishandled funny characters in file names, and anyway it isn't
14332 * data/yacc.c: Likewise.
14333 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
14335 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
14336 * data/yacc.c: Likewise.
14338 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
14340 (muscle_init): Quote filename as a C string.
14341 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
14342 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
14343 * src/output.c (escaped_file_name_output): New function.
14344 (prepare_symbols): Quote tokens for M4.
14345 (prepare): Don't insert output_infix, output_prefix,
14346 output_parser_name, output_header_name; this is now down by scan-skel.
14347 Insert skeleton as a C string.
14349 * src/output.c (user_actions_output, symbol_destructors_output,
14350 symbol_printers_output): Quote filenames for C and M4.
14351 * src/reader.c (prologue_augment, epilogue_set): Likewise.
14353 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
14354 escapes other than \\ and \'; this simplifies the code.
14355 (<SC_STRING>): Likewise, for \\ and \".
14356 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
14357 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
14358 Use new escapes @{ and @} for [ and ].
14360 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
14361 them with auto vars.
14362 Switch to new escape scheme, where @ is the escape character uniformly.
14363 Abort if a stray escape character is found. Avoid unbounded input
14364 buffer when parsing non-escaped text.
14366 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
14367 __oline__, #output, $@, and @{ do not have unintended meanings.
14369 2002-11-09 Paul Eggert <eggert@twinsun.com>
14371 Fix the test failure due to GCC warnings described in
14372 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
14373 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
14374 evaluate to 0 if it's impossible for NINF to be in the respective
14376 (yygetLRActions, yyrecoverParseError): Use them.
14378 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
14379 counted in the token inserted at end of file. Now takes
14380 location_t *, not location_t, so that the location can be
14381 adjusted. All uses changed.
14383 * tests/regression.at (Invalid inputs): Adjust wording in
14384 diagnostic to match the new behavior.
14386 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
14387 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
14388 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))

14395 * src/parse-gram.y (CHARACTER): Remove unused token.
14398 * src/scan-gram.l: Remove stack option. We no longer use the
14399 stack, since the stack was never deeper than 1; instead, use the
14400 new auto var c_context to record the stacked value.
14402 Remove nounput option. At an unexpected end of file, we now unput
14403 the minimal input necessary to end cleanly; this simplifies the
14406 Avoid unbounded token sizes where this is easy.
14408 (unexpected_end_of_file): New function.
14409 Use it to systematize the error message on unexpected EOF.
14410 (last-string): Now auto, not static.

14420 yyerror can be variadic.
14422 * data/yacc.c (b4_yyerror_args): New.
14423 Use it when calling yyerror.
14424 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

14474 * src/scan-gram.l: Use more accurate diagnostics, e.g.
14475 "integer out of range" rather than "invalid value".
14476 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
14479 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
14480 Also, remove one static variable in the scanner.
14482 * src/scan-gram.l (braces_level): Now auto, not static.
14483 Initialize to zero if the compiler is being picky.
14484 (INITIAL): Clear braces_level instead of incrementing it.
14485 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

14487 * src/system.h (IF_LINT): New macro, taken from coreutils.
14488 * configure.ac: Define "lint" if --enable-gcc-warnings.
14490 2002-11-05 Akim Demaille <akim@epita.fr>
14492 * src/scan-gram.l: When it starts with `%', complain about the
14493 whole directive, not just that `invalid character: %'.
14495 2002-11-04 Akim Demaille <akim@epita.fr>
14497 * Makefile.maint: Update from Autoconf.
14498 (update, cvs-update, po-update, do-po-update): New.

14516 Use quote, not quote_n since LOCATION_PRINT no longer uses the
14519 2002-11-03 Paul Eggert <eggert@twinsun.com>
14521 * src/reader.c (get_merge_function, grammar_current_rule_check):
14522 Use consistent diagnostics for reporting type name clashes.
14523 Quote the types with <>, for consistency with Yacc.
14524 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
14526 2002-11-03 Akim Demaille <akim@epita.fr>
14528 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
14530 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
14531 (b4_parse_param): Remove.

14540 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
14541 (yyreportAmbiguity): When using a pure parser, also need
14542 the location, and the parse-params.
14544 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
14545 When using a pure parser, also need the parse-params.
14547 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
14548 (%pure-parser + %parse-param) LALR and GLR parsers.
14549 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
14550 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

14561 2002-11-03 Akim Demaille <akim@epita.fr>
14563 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
14564 AT_CHECK_CALC_GLR invocations to use % directives, instead of
14565 command line options.
14566 * tests/cxx-type.at: Formatting changes.
14568 2002-11-03 Paul Eggert <eggert@twinsun.com>
14570 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
14571 to count columns correctly, and to check for invalid inputs.
14573 Use mbsnwidth to count columns correctly. Account for tabs, too.
14574 Include mbswidth.h.
14575 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
14576 (extend_location): New function.
14577 (YY_LINES): Remove.

14586 Handle backslash-newline correctly in C code.
14587 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
14588 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
14590 (tag, splice): New EREs. Do not allow NUL or newline in tags.
14591 Use {splice} wherever C allows backslash-newline.
14592 YY_STEP after space, newline, vertical-tab.
14593 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
14595 (letter, id): Don't assume ASCII; e.g., spell out a-z.
14597 ({int}, handle_action_dollar, handle_action_at): Check for integer
14600 (YY_STEP): Omit trailing semicolon, so that it's more like C.
14602 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
14603 as well as \000. Check for UCHAR_MAX, not 255.
14604 Allow \x with an arbitrary positive number of digits, as in C.
14605 Check for overflow here.
14606 Allow \? and UCNs, for compatibility with C.
14608 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
14609 with quote slot used by complain_at.
14611 * tests/input.at: Add tests for backslash-newline, m4 quotes
14612 in symbols, long literals, and funny escapes in strings.
14614 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
14615 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

14620 * doc/bison.texinfo (Grammar Outline): Document // comments.
14621 (Symbols): Document that trigraphs have no special meaning in Bison,

14628 2002-11-02 Paul Eggert <eggert@twinsun.com>
14630 * src/reader.c: Don't include quote.h; not needed.
14631 (get_merge_function): Reword warning to be consistent with
14632 type clash diagnostic in grammar_current_rule_check.
14634 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
14635 bug in trigraph handling.
14637 * src/output.c (prepare_symbols): When printing token names,
14638 escape "[" as "@<:@" and likewise for "]".
14640 * src/system.h (errno): Remove declaration, as we are now
14641 assuming C89 or better, and C89 guarantees errno.
14643 2002-10-30 Paul Eggert <eggert@twinsun.com>
14645 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
14646 Check for close failures.
14647 * src/files.h (xfclose): Return void, not int, since it always
14649 * src/files.c (xfclose): Likewise. Report I/O error if ferror
14651 * src/output.c (output_skeleton): Use xfclose rather than fclose
14652 and ferror. xfclose now checks ferror.
14654 * data/glr.c (YYLEFTMOST_STATE): Remove.
14655 (yyreportTree): Use a stack-based leftmost state. This avoids
14656 our continuing battles with bogus warnings about initializers.
14658 2002-10-30 Akim Demaille <akim@epita.fr>
14660 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

14665 * tests/glr-regr1.at: New test for reported regressions.
14666 * tests/testsuite.at: Add glr-regr1.at test.

14673 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
14674 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
14675 we use malloc. Don't assume 'A' through 'Z' are contiguous.
14676 Don't assume strdup exists; POSIX says its an XSI extension.
14677 Check for buffer overflow on input.
14679 2002-10-24 Akim Demaille <akim@epita.fr>
14681 * src/output.c (output_skeleton): Don't disable M4sugar comments
14682 too soon: it results in comments being expanded.
14683 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
14686 2002-10-24 Akim Demaille <akim@epita.fr>
14688 * data/yacc.c (m4_int_type): New.
14689 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
14690 char' as only yacc.c wants K&R portability.
14691 * data/glr.c (yysigned_char): Remove.
14692 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
14693 Reported by Quoc Peyrot.
14695 2002-10-23 Paul Eggert <eggert@twinsun.com>
14697 * src/main.c (main): With --trace=time, report times even if a
14698 non-fatal error occurs. Formerly, the times were reported in some
14699 such cases but not in others.
14700 * src/reader.c (reader): Just return if a complaint has been issued,
14701 instead of exiting, so that 'main' can report times.
14703 2002-10-22 Akim Demaille <akim@epita.fr>
14705 * src/system.h: Include sys/types.
14706 Reported by Bert Deknuydt.
14708 2002-10-23 Paul Eggert <eggert@twinsun.com>
14710 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
14711 Suggested by Art Haas.
14713 2002-10-22 Paul Eggert <eggert@twinsun.com>
14715 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14716 decl; not needed any more.
14717 * src/main.c (main): Use return to exit, undoing yesterday's change.
14718 The last OS that we could find where this wouldn't work is
14719 SunOS 3.5, and that's too old to worry about now.
14721 * data/glr.c (struct yyltype): Define members even when not
14722 doing locations. This is more consistent with yacc.c, and it
14723 works around the following bug reports:
14724 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
14725 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
14727 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
14728 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14729 "Algol" instead of "ALGOL". Give a bit more history about BNF.
14731 2002-10-22 Akim Demaille <akim@epita.fr>
14733 * data/README: New.
14735 2002-10-21 Paul Eggert <eggert@twinsun.com>
14737 Be consistent about 'bool'; the old code used an enum in one
14738 module and an int in another, and this violates the C standard.
14739 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14740 * configure.ac (AC_HEADER_STDBOOL): Add.
14741 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14742 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14743 * src/symtab.c (hash_compare_symbol_t): Likewise.
14744 * src/system.h (bool, false, true): Use a definition consistent
14745 with ../lib/hash.c. All uses changed.
14747 * src/complain.c (warning_issued): Renamed from warn_message_count,
14748 so that we needn't worry about integer overflow (!).
14749 Now of type bool. All uses changed.
14750 (complaint_issued): Renamed from complain_message_count; likewise.
14752 * src/main.c (main): Use exit to exit with failure.
14754 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
14755 rather than 1 and 0.
14756 * src/main.c (main): Likewise.
14757 * src/getargs.c (getargs): Likewise.
14758 * src/reader.c (reader): Likewise.
14760 * src/getarg.c (getargs): Remove duplicate code for
14761 "Try `bison --help'".
14763 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
14764 What was that "2" for?
14766 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14767 * src/getargs.c (usage): Likewise.
14769 * src/getargs.c (getargs): When there are too few operands, report
14770 the last one. When there are too many, report the first extra
14771 one. This is how diffutils does it.
14773 2002-10-20 Paul Eggert <eggert@twinsun.com>
14775 Remove K&R vestiges.
14776 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
14777 * src/complain.c (VA_START): Remove. Assume prototypes.
14778 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
14779 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
14780 fatal): Assume prototypes.
14781 * src/complain.h: Assume prototypes.
14782 * src/system.h (PARAMS): Remove.
14783 Include <limits.h> unconditionally, since it's guaranteeed even
14784 for a freestanding C89 compiler.
14785 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
14786 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
14788 2002-10-20 Akim Demaille <akim@epita.fr>
14790 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
14791 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.

14795 (yy_reduce_print): New.
14796 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.

14800 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14801 arguments and output `void'.
14802 (b4_c_function): Rename as...
14803 (b4_c_function_def): this.
14804 (b4_c_function_decl, b4_c_ansi_function_def)
14805 (b4_c_ansi_function_decl): New.
14806 Change the interpretation of the arguments: before `int, foo', now
14808 * data/yacc.c (yyparse): Prototype and define thanks to these.
14809 Adjust b4_c_function_def uses.
14810 * data/glr.c (yyparse): Likewise, but ANSI only.
14812 2002-10-20 Akim Demaille <akim@epita.fr>
14814 * src/output.c (prepare): Move the definition of `tokens_number',
14815 `nterms_number', `undef_token_number', `user_token_number_max'
14817 (prepare_tokens): Here.
14818 (prepare_tokens): Rename as...
14819 (prepare_symbols): this.
14820 (prepare): Move the definition of `rules_number' to...
14821 (prepare_rules): here.
14822 (prepare): Move the definition of `last', `final_state_number',
14823 `states_number' to...
14824 (prepare_states): here.
14825 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
14827 2002-10-20 Akim Demaille <akim@epita.fr>
14829 * src/tables.h, src/tables.c, src/output.c: Comment changes.
14831 2002-10-20 Akim Demaille <akim@epita.fr>
14833 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
14836 2002-10-20 Akim Demaille <akim@epita.fr>
14838 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
14839 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
14841 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
14843 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
14844 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
14847 2002-10-19 Paul Eggert <eggert@twinsun.com>
14849 Do not create a temporary file, as that involves security and
14850 cleanup headaches. Instead, use a pair of pipes.
14851 Derived from a suggestion by Florian Krohm.
14852 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14853 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

14859 * po/POTFILES.in: Add lib/subpipe.c.
14860 * src/output.c: Include "subpipe.h".
14861 (m4_invoke): Remove decl.
14862 (scan_skel): New decl.
14863 (output_skeleton): Use pipe rather than temporary file for m4 input.
14864 Check that m4sugar.m4 is readable, to avoid deadlock.
14865 Check for pipe I/O error.
14866 * src/scan-skel.l (readpipe): Remove decl.
14867 (scan_skel): New function, to be used in place of m4_invoke.
14868 Read from stream rather than file.
14870 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14871 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14872 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14873 this generates a more-accurate value anyway.
14875 * lib/timevar.c (timervar_accumulate): Rename locals to
14876 avoid confusion with similarly-named more-global.
14877 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14879 * src/output.c (prepare): Use xstrdup to convert char const *
14880 to char *, to avoid GCC warning.
14882 2002-10-19 Akim Demaille <akim@epita.fr>
14884 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14885 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14886 Use them to have `calc.y' ready for %pure-parser.
14887 * data/yacc.c (YYLEX): Pass a yylex return type to
14888 b4_c_function_call.
14890 2002-10-19 Akim Demaille <akim@epita.fr>
14892 Prototype support of %lex-param and %parse-param.
14894 * src/parse-gram.y: Add the definition of the %lex-param and
14895 %parse-param tokens, plus their rules.
14896 Drop the `_' version of %glr-parser.
14898 * src/scan-gram.l (INITIAL): Scan them.
14899 * src/muscle_tab.c: Comment changes.
14900 (muscle_insert, muscle_find): Rename `pair' as `probe'.
14901 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
14902 (muscle_entry_s): The `value' member is no longer const.
14903 Adjust all dependencies.
14904 * src/muscle_tab.c (muscle_init): Adjust: use
14905 MUSCLE_INSERT_STRING.
14906 Initialize the obstack earlier.
14907 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14908 (muscle_pair_list_grow): New.
14909 * data/c.m4 (b4_c_function_call, b4_c_args): New.
14910 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
14911 * tests/calc.at: Use %locations, not --locations.
14912 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14914 2002-10-19 Akim Demaille <akim@epita.fr>
14916 * src/getargs.c (usage): Take status as argument and exit
14918 Report the traditional `Try ... --help' message when status != 0.
14919 (usage, version): Don't take a FILE * as arg, it is pointless.
14920 (getargs): When there is an incorrect number of arguments, make it
14921 an error, and report it GNUlically thanks to `usage ()'.
14923 2002-10-18 Paul Eggert <eggert@twinsun.com>
14925 * data/glr.c (yyreportParseError): Don't assume that sprintf
14926 yields the length of the printed string, as this is not true
14927 on SunOS 4.1.4. Reported by Peter Klein.
14929 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14930 * tests/conflicts.at (%nonassoc and eof): Likewise.
14931 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14933 2002-10-17 Akim Demaille <akim@epita.fr>
14935 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14936 * src/getargs.c (trace_types, trace_args): Adjust.
14937 * src/reader.c (grammar_current_rule_prec_set)
14938 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
14939 Standardize error messages.
14940 And s/@prec/%prec/!
14941 (reader): Use trace_flag to enable scanner/parser debugging,
14942 instead of an adhoc scheme.
14943 * src/scan-gram.l: Remove trailing debugging code.
14945 2002-10-16 Paul Eggert <eggert@twinsun.com>
14947 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
14950 * NEWS: Officially drop support for building Bison with K&R C,
14951 since it didn't work anyway and it's not worth worrying about.
14952 * Makefile.maint (wget_files): Remove ansi2knr.c.
14953 (ansi2knr.c-url_prefix): Remove.
14954 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
14955 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14956 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14958 2002-10-15 Paul Eggert <eggert@twinsun.com>
14960 Stop using the "enum_" trick for K&R-style function definitions;
14961 it confused me, and I was the author! Instead, assume that people
14962 who want to use K&R C compilers (when using these modules in GCC,
14963 perhaps?) will run ansi2knr.
14965 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
14966 All uses of "enum_" changed to "enum ".
14967 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14968 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14970 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

14978 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
14979 Use function prototypes; this removes the need for declaring
14980 static functions simply to provide their prototypes.
14981 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

15040 * tests/Makefile.am (maintainer-check-posix): New.
15042 2002-10-14 Akim Demaille <akim@epita.fr>
15044 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
15047 2002-10-14 Akim Demaille <akim@epita.fr>
15049 * src/tables.c (table_ninf_remap): base -> tab.
15050 Reported by Matt Rosing.
15052 2002-10-14 Paul Eggert <eggert@twinsun.com>
15054 * tests/action.at, tests/calc.at, tests/conflicts.at,
15055 tests/cxx-type.at, tests/headers.at, tests/input.at,
15056 tests/regression.at, tests/synclines.at, tests/torture.at:
15057 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
15058 so that the tests still work even if POSIXLY_CORRECT is set.
15059 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
15061 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
15062 for portability to K&R hosts. Fix typo: signed char is guaranteed
15063 only to 127, not to 128.
15064 * data/glr.c (yysigned_char): New type.
15065 * data/yacc.c (yysigned_char): Likewise.
15066 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
15068 2002-10-13 Paul Eggert <eggert@twinsun.com>
15070 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
15071 true due to limited range of data type" warning from GCC.
15073 * data/c.m4 (b4_token_defines): Protect against double-inclusion
15074 by wrapping enum yytokentype's definition inside #ifndef
15075 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
15077 2002-10-13 Akim Demaille <akim@epita.fr>
15079 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
15080 Un yy- yyrhs to avoid the name clash with the global YYRHS.
15082 2002-10-13 Akim Demaille <akim@epita.fr>
15084 * Makefile.maint: Update from Autoconf 2.54.
15085 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
15087 2002-10-13 Akim Demaille <akim@epita.fr>
15089 * src/print.c (print_state): Separate the list of solved conflicts
15090 from the other items.
15091 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
15093 2002-10-13 Akim Demaille <akim@epita.fr>
15095 Let nondeterministic skeletons be usable with deterministic
15098 With the patch, GAWK compiled by GCC without -O2 passes its test
15099 suite using a GLR parser driven by LALR tables. It fails with -O2
15100 because `struct stat' gives two different answers on my machine:
15101 88 (definition of an auto var) and later 96 (memset on this var).
15102 Hence the stack is badly corrumpted. The headers inclusion is to
15103 blame: if I move the awk.h inclusion before GLR's system header
15104 inclusion, the two struct stat have the same size.
15106 * src/tables.c (pack_table): Always create conflict_table.
15107 (token_actions): Always create conflict_list.
15108 * data/glr.c (YYFLAG): Remove, unused.
15110 2002-10-13 Akim Demaille <akim@epita.fr>
15112 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
15114 (VALGRIND, GXX): New.
15115 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
15116 * tests/bison.in: Run $PREBISON a pre-command.
15117 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
15118 (maintainer-check-g++): New.
15119 * Makefile.am (maintainer-check): New.
15121 2002-10-13 Akim Demaille <akim@epita.fr>
15123 * data/glr.c: Formatting changes.
15124 Tweak some trace messages to match yacc.c's.
15126 2002-10-13 Akim Demaille <akim@epita.fr>
15128 GLR parsers sometimes raise parse errors instead of performing the
15130 Reported by Charles-Henry de Boysson.
15132 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
15133 check the length of the traces when %glr.
15134 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
15136 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
15138 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
15139 (yyltype): Remove the yy prefix from the member names.
15140 (yytable): Complete its comment.
15141 (yygetLRActions): Map error action number from YYTABLE from
15143 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
15144 (which was a bug: it should have been YYTABEL_NINF, and yet it was
15145 not satisfying as we could compare an YYACTION computed from
15146 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
15147 only value for error actions.
15148 (yyreportParseError): In verbose parse error messages, don't issue
15149 `error' in the list of expected tokens.
15150 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
15151 next action to perform to match glr.c's decoding.
15152 (yytable): Complete its comment.
15154 2002-10-13 Paul Eggert <eggert@twinsun.com>
15156 Fix problem reported by Henrik Grubbstroem in
15157 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
15158 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
15159 because the Bison parser reads the second action before reducing
15161 * src/scan-gram.l (rule_length): New static var.
15162 Use it to keep track of the rule length in the scanner, since
15163 we can't expect the parser to be in lock-step sync with the scanner.
15164 (handle_action_dollar, handle_action_at): Use this var.
15165 * tests/actions.at (Exotic Dollars): Test for the problem.
15167 2002-10-12 Paul Eggert <eggert@twinsun.com>
15169 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
15170 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
15171 Include <sys/time.h> when checking for clock_t and struct tms.
15172 Use same include order as source.
15173 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
15174 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
15176 * lib/timevar.c: Update copyright date and clarify comments.
15177 (get_time) [IN_GCC]: Keep the GCC version for reference.
15179 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
15180 GCC version as of today, then merge Bison's changes.
15181 Change "GCC" to "Bison" in copyright notice. timevar.def's
15182 author is Akim, so change that too.
15184 * src/reader.c (grammar_current_rule_check):
15185 Don't worry about the default action if $$ is untyped.
15186 Prevents bogus warnings reported by Jim Gifford in
15187 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
15189 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
15190 * data/glr.c, data/lalr1.cc, data/yacc.c:
15191 Output token definitions before the first part of user declarations.
15192 Fixes compatibility problem reported by Jim Gifford for kbd in
15193 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
15195 2002-10-11 Paul Eggert <eggert@twinsun.com>
15197 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
15198 (yyparse): here. This undoes some of the 2002-07-25 change.
15199 Compatibility problem reported by Ralf S. Engelschall with
15200 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

15219 * lib/lbitset.c: Likewise.
15221 * lib/abitset.c (abitset_bytes): Return a size that is aligned
15222 properly for vectors of objects. Do not assume that adding a

15224 properly aligned for the whole union.

15264 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15265 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15267 Do not use "struct bitset_struct" to mean different things in
15268 different modules. Not only is this confusing, it violates
15269 the C Standard, which requires that structure types in different
15270 modules must be compatible if one is to be passed to the other.
15271 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
15272 All instances of "struct bitset_struct *" replaced with "bitset".

15287 Do not call a function of type T using a call that assumes the
15288 function is of a different type U. Standard C requires that a
15289 function must be called with a type that is compatible with its

15314 2002-10-06 Paul Eggert <eggert@twinsun.com>
15316 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
15317 the same width as int. This reapplies a hunk of the 2002-08-12 patch
15318 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
15319 which was inadvertently undone by the 2002-09-30 patch.
15320 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
15321 the same width as int.

15345 * src/reader.c (reader): Use it.
15347 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
15348 POSIX 1003.1-2001 has removed fgrep.

15423 to BITSET_WINDEX_MAX.
15425 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
15426 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

15623 PROTOTYPES to check for prototypes, and "defined __STDC__" to

15672 * src/main.c (main): Cast result of bindtextdomain and textdomain
15673 to void, to avoid a GCC warning when --disable-nls is in effect.
15675 * src/scan-gram.l: Use strings rather than escapes when possible,
15676 to minimize the number of warnings from xgettext.
15677 (handle_action_dollar, handle_action_at): Don't use isdigit,
15678 as it mishandles negative chars and it may not work as expected
15679 outside the C locale.
15681 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
15682 this is a GCC extension and is not portable to other compilers.

15921 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
15922 for the time being: %locations ought to provide it to yyerror.

17901 * data/bison.c++, data/bison.simple: Don't output the current file
17902 name in #line, to avoid useless diffs between two identical

17907 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

18118 * src/L0.c, src/LR0.h (nstates): Be size_t.
18119 Adjust comparisons (signed vs unsigned).
18120 * src/conflics.c, src/lalr.c, src/lalr.h, src/output.c (LA): Now a

18124 2002-03-04 Akim Demaille <akim@epita.fr>
18126 * src/closure.c (firsts): Now, also a bitset.
18127 Adjust all dependencies.
18128 (varsetsize): Remove, now unused.
18129 * src/warshall.h, src/warshall.c: Now work on arrays of bitsets.
18131 2002-03-04 Akim Demaille <akim@epita.fr>
18133 * src/print.c: Convert to use bitset.h, not hand coded iterations
18136 2002-03-04 Akim Demaille <akim@epita.fr>
18138 * src/reduce.c: Convert to use bitset.h, not hand coded BSet.
18140 2002-03-04 Akim Demaille <akim@epita.fr>
18142 * src/closure.c (ruleset): Be a bitset.
18143 (rulesetsize): Remove.
18145 2002-03-04 Akim Demaille <akim@epita.fr>
18147 * lib/bitset-int.h, lib/bitset.c, lib/bitset.h, lib/bitsetv.c,

18149 * lib/lbitset.h, lib/sbitset.c, lib/sbitset.h: New.
18150 * src/closure.c (fderives): Be an array of bitsets.
18152 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
18154 * data/bison.c++: Merge the two generated headers. Insert a copyright
18155 notice in each output file.
18157 2002-02-28 Akim Demaille <akim@epita.fr>
18159 * data/bison.c++: Copy the prologue of bison.simple to fetch
18160 useful M4 definitions, such as b4_header_guard.
18162 2002-02-25 Akim Demaille <akim@epita.fr>
18164 * src/getargs.c (version): Give the name of the authors, and use a
18165 translator friendly scheme for the bgr
18168 2002-02-25 Akim Demaille <akim@epita.fr>
18170 * src/output.c (header_output): Remove, now handled completely via
18173 2002-02-25 Akim Demaille <akim@epita.fr>
18175 * m4/m4.m4: New, from CVS Autoconf.
18176 * configure.in: Invoke it.
18177 * src/output.c (output_skeleton): Use its result instead of the
18180 2002-02-25 Akim Demaille <akim@epita.fr>
18182 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
18184 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
18185 * src/output.c (output_skeleton): Use mkstemp to create a real
18187 Move the filling of `skeleton' and its muscle to...
18189 (output): Move the definition of the prologue muscle to...
18191 * src/system.h (DEFAULT_TMPDIR): New.
18193 2002-02-14 Paul Eggert <eggert@twinsun.com>
18195 Remove the support for C++ namespace cleanliness; it was
18196 causing more problems than it was curing, since it didn't work
18197 properly on some nonstandard C++ compilers. This can wait
18198 for a proper C++ parser.
18200 * NEWS: Document this.
18201 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
18202 of C++, as it's treated like C now.
18203 * src/bison.simple (YYSTD): Remove.
18204 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
18205 Treat C++ just like Standard C instead of trying to support
18206 namespace cleanliness.
18208 2002-02-14 Akim Demaille <akim@epita.fr>
18210 * tests/regression.at (else): Adjust to Andreas' change.
18212 2002-02-14 Akim Demaille <akim@epita.fr>
18214 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
18216 2002-02-13 Andreas Schwab <schwab@suse.de>
18218 * src/output.c (output_rule_data): Don't output NULL, it might
18219 not be defined yet.
18221 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
18223 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
18224 (Copyright notice): Update.
18226 2002-02-11 Akim Demaille <akim@epita.fr>
18228 * tests/regression.at (%nonassoc and eof): Don't include
18229 nonportable headers.
18231 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
18233 * data/bison.c++: Correct error recovery. Make the user able to
18234 initialize the starting location.
18236 2002-02-07 Akim Demaille <akim@epita.fr>
18238 * tests/input.at: New.
18240 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18242 * data/bison.c++: Replace some direct m4 expansions by constants. Be
18243 more consistent when naming methods and variables. Put preprocessor
18244 directives around tables only needed for debugging.
18246 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18248 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
18250 (yy::b4_name::parse): Use print_.
18252 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18254 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
18256 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18258 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
18260 (yy::b4_name::parse): Build verbose error messages, and use error_.
18262 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
18264 * data/bison.c++: Fix m4 quoting in comments.
18266 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
18268 * data/bison.c++: Adjust the parser code. Fix some muscles that were
18269 not expanded by m4.
18271 2002-02-05 Akim Demaille <akim@epita.fr>
18273 * data/bison.c++: Adjust to the M4 back end.
18274 More is certainly needed.
18276 2002-02-05 Akim Demaille <akim@epita.fr>
18278 Give a try to M4 as a back end.
18280 * lib/readpipe.c: New, from wdiff.
18281 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
18283 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
18284 specific values. Now it is m4 that performs the lookup.
18285 * src/parse-skel.y: Remove.
18286 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
18287 * src/output.c (actions_output, guards_output)
18288 (token_definitions_output): No longer keeps track of the output
18289 line number, hence remove the second argument.
18290 (guards_output): Check against the guard member of a rule, not the
18293 (output_skeleton): Don't look for the skeleton location, let m4 do
18295 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
18297 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
18298 (prepare): Given that for the time being changesyntax is not
18299 usable in M4, rename the muscles using `-' to `_'.
18300 Define `defines_flag', `output_parser_name' and `output_header_name'.
18301 * src/output.h (actions_output, guards_output)
18302 (token_definitions_output): Adjust prototypes.
18303 * src/scan-skel.l: Instead of scanning the skeletons, it now
18304 processes the output of m4: `__oline__' and `#output'.
18305 * data/bison.simple: Adjust to be used by M4(sugar).
18306 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
18308 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
18309 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
18310 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
18311 shamelessly stolen from CVS Autoconf.
18313 2002-02-05 Akim Demaille <akim@epita.fr>
18315 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
18316 * configure.in: Check for the declarations of free and malloc.
18317 * src/muscle_tab.c: Adjust.
18319 2002-02-05 Akim Demaille <akim@epita.fr>
18321 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
18322 which have no values.
18324 2002-02-05 Akim Demaille <akim@epita.fr>
18326 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
18329 2002-01-29 Paul Eggert <eggert@twinsun.com>
18331 * src/bison.simple (YYSIZE_T): Do not define merely because
18332 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
18333 On some platforms, <alloca.h> does not declare YYSTD (size_t).
18335 2002-01-27 Akim Demaille <akim@epita.fr>
18337 Fix `%nonassoc and eof'.
18339 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
18340 which were not properly copied! Replace
18341 memcpy (res->errs, src->errs, src->nerrs);
18343 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
18345 * tests/regression.at (%nonassoc and eof): Adjust to newest
18346 Autotest: `.' is not in the PATH.
18348 2002-01-27 Akim Demaille <akim@epita.fr>
18350 * tests/sets.at (AT_EXTRACT_SETS): New.
18351 (Nullable): Use it.
18354 2002-01-26 Akim Demaille <akim@epita.fr>
18356 * tests/actions.at, tests/calc.at, tests/headers.at,
18357 * tests/torture.at: Adjust to the newest Autotest which no longer
18358 forces `.' in the PATH.
18360 2002-01-25 Akim Demaille <akim@epita.fr>
18362 * tests/regression.at (%nonassoc and eof): New.
18363 Suggested by Robert Anisko.
18365 2002-01-24 Akim Demaille <akim@epita.fr>
18367 Bison dumps core when trying to complain about broken input files.
18368 Reported by Cris van Pelt.
18370 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
18371 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
18373 (Invalid inputs): Strengthen: exercise parse_percent_token.
18375 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
18377 * src/Makefile.am: Add bison.c++.
18378 * src/bison.c++: New skeleton.
18380 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
18384 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
18386 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
18388 2002-01-20 Marc Autret <marc@gnu.org>
18390 * src/files.c (compute_output_file_names): Fix
18392 2002-01-20 Marc Autret <marc@gnu.org>
18394 * tests/output.at: New test.
18395 * src/files.c (compute_base_names): Don't map extensions when
18396 the YACC flag is set, use defaults.
18397 Reported by Evgeny Stambulchik.
18399 2002-01-20 Marc Autret <marc@gnu.org>
18401 * src/system.h: Need to define __attribute__ away for non-GCC
18402 compilers as well (i.e., the vendor C compiler).
18403 Suggested by Albert Chin-A-Young.
18405 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
18407 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
18408 canonical definition.
18409 * src/system.h: Use the canonical definition for PARAMS (avoids
18410 a conflict with the macro from lib/hash.h).
18412 2002-01-11 Akim Demaille <akim@epita.fr>
18414 * configure.in: Use AC_FUNC_STRNLEN.
18415 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
18417 2002-01-09 Akim Demaille <akim@epita.fr>
18419 * src/files.c, src/files.h (output_infix): New.
18420 (tab_extension): Remove.
18421 (compute_base_names): Compute the former, drop the latter.
18422 * src/output.c (prepare): Insert the muscles `output-infix', and
18424 * src/parse-skel.y (string, string.1): New.
18425 (section.header): Use it.
18426 (section.yacc): Remove.
18427 (prefix): Remove too.
18428 * src/scan-skel.l: Adjust.
18429 * src/bison.simple, src/bison.hairy: Adjust.
18431 2002-01-09 Akim Demaille <akim@epita.fr>
18433 * configure.in (WERROR_CFLAGS): Compute it.
18434 * src/Makefile.am (CFLAGS): Pass it.
18435 * tests/atlocal.in (CFLAGS): Idem.
18436 * src/files.c: Fix a few warnings.
18437 (get_extension_index): Remove, unused.
18439 2002-01-08 Akim Demaille <akim@epita.fr>
18441 * src/getargs.c (AS_FILE_NAME): New.
18442 (getargs): Use it to convert DOSish file names.
18443 * src/files.c (base_name): Rename as full_base_name to avoid
18444 clashes with `base_name ()'.
18445 (filename_split): New.
18446 (compute_base_names): N-th rewrite, using filename_split.
18448 2002-01-08 Akim Demaille <akim@epita.fr>
18450 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
18451 New, stolen from the Fileutils 4.1.
18452 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
18453 * configure.in: Check for the presence of memrchr, and of its
18456 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
18458 * lib/hash.h (__P): Added definition for this macro.
18459 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
18460 BUILT_SOURCES, to ensure they are generated first.
18461 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
18462 %error-verbose to allow bootstrapping with bison 1.30x.
18464 2002-01-06 Akim Demaille <akim@epita.fr>
18466 * src/reader.c (parse_braces): Don't fetch the next char, the
18467 convention is to fetch on entry.
18468 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
18469 'switch' without a following semicolon.
18470 * tests/regression.at (braces parsing): New.
18472 2002-01-06 Akim Demaille <akim@epita.fr>
18474 Bison is dead wrong in its RR conflict reports.
18476 * tests/torture.at (GNU Cim Grammar): New.
18477 * src/conflicts.c (count_rr_conflicts): Fix.
18479 2002-01-06 Akim Demaille <akim@epita.fr>
18481 Creating package.m4 from configure.ac causes too many problems.
18483 * tests/Makefile.am (package.m4): Create it by hand,
18484 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
18486 2002-01-06 Akim Demaille <akim@epita.fr>
18488 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
18491 2002-01-04 Paul Eggert <eggert@twinsun.com>
18493 * doc/bison.texinfo (Debugging):
18494 Remove YYSTDERR; it's no longer defined or used.
18495 Also, s/cstdio.h/cstdio/.
18497 2002-01-03 Akim Demaille <akim@epita.fr>
18499 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
18501 2002-01-03 Akim Demaille <akim@epita.fr>
18503 * src/parse-skel.y (process_skeleton): Don't bind the parser's
18504 tracing code to --trace, wait for a better --trace option, with
18507 2002-01-03 Akim Demaille <akim@epita.fr>
18509 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
18510 The ISO C++ standard is extremely clear about it: stderr is
18511 considered a macro, not a regular symbol (see table 94 `Header
18512 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
18513 Therefore std:: does not apply to it. It still does with fprintf.
18514 Also, s/cstdio.h/cstdio/.
18516 2002-01-03 Akim Demaille <akim@epita.fr>
18518 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
18519 for non system headers.
18521 2002-01-02 Akim Demaille <akim@epita.fr>
18523 Equip the skeleton chain with location tracking, runtime trace,
18524 pure parser and scanner.
18526 * src/parse-skel.y: Request a pure parser, locations, and prefix
18528 (%union): Having several members with the same type does not help
18529 type mismatches, simplify.
18530 (YYPRINT, yyprint): New.
18531 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
18532 (skel_error): this.
18534 * src/scan-skel.l: Adjust to these changes.
18535 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
18536 (LOCATION_PRINT, skel_control_t): New.
18538 2001-12-30 Akim Demaille <akim@epita.fr>
18540 * src/parse-skel.y: Get rid of the shift/reduce conflict:
18541 replace `gb' with BLANKS.
18542 * src/scan-skel.l: Adjust.
18544 2001-12-30 Akim Demaille <akim@epita.fr>
18546 * src/system.h: We don't need nor want bcopy.
18547 Throw away MS-DOS crap: we don't need getpid.
18548 * configure.in: We don't need strndup. It was even causing
18549 problems: because Flex includes the headers *before* us,
18550 _GNU_SOURCE is not defined by config.h, and therefore strndup was
18552 * lib/xstrndup.c: New.
18553 * src/scan-skel.l: Use it.
18554 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
18555 * src/parse-skel.y: Use %directives instead of #defines.
18557 2001-12-30 Akim Demaille <akim@epita.fr>
18559 * src/skeleton.h: New.
18560 * src/output.c (output_parser, output_master_parser): Remove, dead
18562 * src/output.h (get_lines_number, actions_output, guards_output)
18563 (token_definitions_output): Prototype them.
18564 * src/parse-skel.y: Add the license notice.
18565 Include output.h and skeleton.h.
18566 (process_skeleton): Returns void, and takes a single parameter.
18567 * src/scan-skel.l: Add the license notice.
18568 Include skeleton.h.
18569 Don't use %option yylineno: it seems that then Flex imagines
18570 REJECT has been used, and therefore it won't reallocate its
18571 buffers (which makes no other sense to me than a bug). It results
18572 in warnings for `unused: yy_flex_realloc'.
18574 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
18576 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
18577 (MUSCLE_INSERT_PREFIX): ...to there.
18578 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
18579 (MUSCLE_INSERT_PREFIX): Move from here...
18581 * src/bison.hairy: Add a section directive. Put braces around muscle
18582 names. This parser skeleton is still broken, but Bison should not
18583 choke on a bad muscle 'syntax'.
18584 * src/bison.simple: Add a section directive. Put braces around muscle
18587 * src/files.h (strsuffix, stringappend): Add declarations.
18588 (tab_extension): Add declaration.
18589 (short_base_name): Add declaration.
18591 * src/files.c (strsuffix, stringappend): No longer static. These
18592 functions are used in the skeleton parser.
18593 (tab_extension): New.
18594 (compute_base_names): Use the computations done in this function
18595 to guess if the generated parsers should have '.tab' in their
18597 (short_base_name): No longer static.
18599 * src/output.c (output_skeleton): New.
18600 (output): Disable call to output_master_parser, and give a try to
18601 a new skeleton handling system.
18602 (guards_output, actions_output): No longer static.
18603 (token_definitions_output, get_lines_number): No longer static.
18605 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
18607 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
18610 * src/parse-skel.y: New file.
18611 * src/scan-skel.l: New file.
18613 2001-12-29 Akim Demaille <akim@epita.fr>
18615 %name-prefix is broken.
18617 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
18618 Adjust all dependencies.
18619 * tests/headers.at (export YYLTYPE): Strengthen this test: use
18622 Renaming yylval but not yylloc is not consistent. Now we do.
18624 * src/bison.simple: Prefix yylloc if used.
18625 * doc/bison.texinfo (Decl Summary): Document that.
18627 2001-12-29 Akim Demaille <akim@epita.fr>
18629 * doc/bison.texinfo: Promote `%long-directive' over
18631 Remove all references to fixed-output-files, yacc is enough.
18633 2001-12-29 Akim Demaille <akim@epita.fr>
18635 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
18636 user prologue. These are defaults.
18637 * tests/actions.at (Mid-rule actions): Make sure the user can
18638 define YYDEBUG and YYERROR_VERBOSE.
18640 2001-12-29 Akim Demaille <akim@epita.fr>
18642 * src/output.c (header_output): Don't forget to export YYLTYPE and
18644 * tests/headers.at (export YYLTYPE): New, make sure it does.
18645 * tests/regression.at (%union and --defines, Invalid CPP headers):
18647 * tests/headers.at: here.
18649 2001-12-29 Akim Demaille <akim@epita.fr>
18651 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
18653 2001-12-29 Akim Demaille <akim@epita.fr>
18655 * tests/actions.at (Mid-rule actions): Output on a single line
18656 instead of several.
18658 2001-12-29 Akim Demaille <akim@epita.fr>
18660 * doc/bison.texinfo: Formatting changes.
18662 2001-12-29 Akim Demaille <akim@epita.fr>
18664 Don't store the token defs in a muscle, just be ready to output it
18665 on command. Now possible via `symbols'. Fixes a memory leak.
18667 * src/output.c (token_definitions_output): New.
18668 (output_parser, header_output): Use it.
18669 * src/reader.c (symbols_save): Remove.
18671 2001-12-29 Akim Demaille <akim@epita.fr>
18673 * src/bison.simple: Do not provide a default for YYSTYPE and
18674 YYLTYPE before the user's prologue. Otherwise it's hardly... a
18677 2001-12-29 Akim Demaille <akim@epita.fr>
18679 Mid-rule actions are simply... ignored!
18681 * src/reader.c (readgram): Be sure to attach mid-rule actions to
18682 the empty-rule associated to the dummy symbol, not to the host
18684 * tests/actions.at (Mid-rule actions): New.
18686 2001-12-29 Akim Demaille <akim@epita.fr>
18690 * src/reader.c (reader): Free grammar.
18692 2001-12-29 Akim Demaille <akim@epita.fr>
18696 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
18697 since it allocates it for each state, although only one is needed.
18698 (allocate_storage): Do it here.
18700 2001-12-29 Akim Demaille <akim@epita.fr>
18702 * src/options.h, src/options.c (create_long_option_table): Rename
18704 (long_option_table_new): this, with a clearer prototype.
18705 (percent_table): Remove, unused,
18706 * src/getargs.c (getargs): Adjust.
18708 2001-12-29 Akim Demaille <akim@epita.fr>
18710 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
18711 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
18714 2001-12-29 Akim Demaille <akim@epita.fr>
18716 * src/lalr.c (build_relations): Rename `states' as `states1'.
18717 Sorry, I don't understand exactly what it is, no better name...
18719 2001-12-29 Akim Demaille <akim@epita.fr>
18721 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
18722 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

18738 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
18739 Adjust all users to use symbols[i]->prec or ->assoc.

18743 * src/reader.c, src/reader.h (tags): Remove.
18744 Adjust all users to use symbols[i]->tag.
18746 2001-12-29 Akim Demaille <akim@epita.fr>
18748 * src/gram.h, src/gram.c (symbols): New, similar to state_table
18750 * src/reader.c (packsymbols): Fill this table.
18752 * src/conflicts.c (resolve_sr_conflict): Adjust.
18753 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
18755 Use symbols[i]->tag instead of tags[i].
18757 2001-12-29 Akim Demaille <akim@epita.fr>
18759 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
18760 In addition, put a comment in there, to replace...
18761 * tests/regression.at (%union and C comments): Remove.
18763 2001-12-29 Akim Demaille <akim@epita.fr>
18765 * tests/regression.at (Web2c Actions): Blindly move the actual
18766 output as expected output. The contents *seem* right to me, but I
18767 can't pretend reading perfectly parser tables... Nonetheless, all
18768 the other tests pass correctly, the table look OK, even though the
18769 presence of `$axiom' is to be noted: AFAICS it is useless (but
18772 2001-12-29 Akim Demaille <akim@epita.fr>
18774 * src/reader.c (readgram): Don't add the rule 0 if there were no
18775 rules read. In other words, add it _after_ having performed
18776 grammar sanity checks.
18777 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
18779 2001-12-29 Akim Demaille <akim@epita.fr>
18781 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
18782 visible, and some states have now a different number.
18784 2001-12-29 Akim Demaille <akim@epita.fr>
18786 * src/reader.c (readgram): Bind the initial rule's lineno to that
18788 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18789 (Solved SR Conflicts): Adjust rule 0's line number.
18791 2001-12-29 Akim Demaille <akim@epita.fr>
18793 Fix the `GAWK Grammar' failure.
18795 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18796 the reductions of the first state which was mistakenly confused
18797 with the final state because precisely final_state was initialized
18799 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18800 now noticed by Bison.
18801 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18802 have a reduction on $default.
18804 2001-12-29 Akim Demaille <akim@epita.fr>
18806 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18808 * src/closure.c (print_closure): Likewise.
18809 * src/derives.c (print_derives): Likewise.
18810 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18813 2001-12-29 Akim Demaille <akim@epita.fr>
18815 * src/lalr.c (lookaheads_print): New.
18816 (lalr): Call it when --trace-flag.
18817 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18820 2001-12-29 Akim Demaille <akim@epita.fr>
18822 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18823 when walking through ritem, even via rule->rhs.
18824 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18825 (useful_production, useless_nonterminals): Likewise.
18826 (reduce_grammar_tables): Likewise, plus update nritems.
18827 * src/nullable.c (set_nullable): Likewise.
18828 * src/lalr.c (build_relations): Likewise.
18829 * tests/sets.at (Nullable): Adjust.
18830 Fortunately, now, the $axiom is no longer nullable.
18832 2001-12-29 Akim Demaille <akim@epita.fr>
18834 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

18837 * src/reduce.c (nonterminals_reduce): Likewise.
18838 * src/print_graph.c (print_graph): Likewise.
18839 * src/output.c (output_rule_data): Likewise.
18840 * src/nullable.c (set_nullable): Likewise.
18842 2001-12-29 Akim Demaille <akim@epita.fr>
18844 * src/output.c: Comment changes.
18846 2001-12-27 Paul Eggert <eggert@twinsun.com>
18848 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18849 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18850 Sparc, as they were causing more porting problems than the
18851 (minor) performance improvement was worth.
18853 Also, catch up with 1.31's YYSTD.
18855 2001-12-27 Akim Demaille <akim@epita.fr>
18857 * src/output.c (output_gram): Rely on nritems, not the
18858 0-sentinel. See below.
18859 Use -1 as separator, not 0.
18860 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18861 Rely on -1 as separator in yyrhs, instead of 0.
18862 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18863 twice `Now at end of input', therefore there are two lines less to
18866 2001-12-27 Akim Demaille <akim@epita.fr>
18868 * tests/regression.at (Unresolved SR Conflicts):
18869 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18872 2001-12-27 Akim Demaille <akim@epita.fr>
18874 * src/LR0.c (new_state): Recognize the final state by the fact it
18875 is reached by eoftoken.
18876 (insert_start_shifting_state, insert_eof_shifting_state)
18877 (insert_accepting_state, augment_automaton): Remove, since now
18878 these states are automatically computed from the initial state.
18879 (generate_states): Adjust.
18880 * src/print.c: When reporting a rule number to the user, substract
18881 1, so that the axiom rule is rule 0, and the first user rule is 1.
18882 * src/reduce.c: Likewise.
18883 * src/print_graph.c (print_core): For the time being, just as for
18884 the report, depend upon --trace-flags to dump the full set of
18886 * src/reader.c (readgram): Once the grammar read, insert the rule
18887 0: `$axiom: START-SYMBOL $'.
18888 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18889 number of the states has changed (the final state is no longer
18890 necessarily the last), catch up.
18892 2001-12-27 Akim Demaille <akim@epita.fr>
18894 Try to make the use of the eoftoken valid. Given that its value
18895 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18896 is used instead of > 0 where appropriate, (ii), depend upon nritems
18897 instead of the 0-sentinel.
18899 * src/gram.h, src/gram.c (nritems): New.
18900 Expected to be duplication of nitems, but for the time being...
18901 * src/reader.c (packgram): Assert nritems and nitems are equal.
18902 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18903 * src/closure.c (print_closure, print_fderives): Likewise.

18905 * src/print.c (print_core, print_grammar): Likewise.
18906 * src/print_graph.c: Likewise.
18908 2001-12-27 Akim Demaille <akim@epita.fr>
18910 * src/main.c (main): If there are complains after grammar
18911 reductions, then output the report anyway if requested, then die.
18912 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18913 * src/reader.c (eoftoken): New.
18914 (parse_token_decl): If the token being defined has value `0', it
18916 (packsymbols): No longer hack `tags' to insert `$' by hand.
18917 Be sure to preserve the value of the eoftoken.
18918 (reader): Make sure eoftoken is defined.
18919 Initialize nsyms to 0: now eoftoken is created just like the others.
18920 * src/print.c (print_grammar): Don't special case the eof token.
18921 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18922 lie anyway, albeit pleasant.
18923 * tests/calc.at: Exercise error messages with eoftoken.
18924 Change the grammar so that empty input is invalid.
18925 Adjust expectations.
18926 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18928 2001-12-27 Akim Demaille <akim@epita.fr>
18930 * configure.in: Check the protos of strchr ans strspn.
18931 Replace strchr if needed.
18932 * src/system.h: Provide the protos of strchr, strspn and memchr if
18934 * lib/strchr.c: New.
18935 * src/reader.c (symbols_save): Use strchr.
18937 2001-12-27 Akim Demaille <akim@epita.fr>
18939 * src/print.c, src/print_graph.c (escape): New.
18940 Use it to quote the TAGS outputs.
18941 * src/print_graph.c (print_state): Now errors are in red, and
18942 reductions in green.
18943 Prefer high to wide: output the state number on a line of its own.
18945 2001-12-27 Akim Demaille <akim@epita.fr>
18947 * src/state.h, src/state.c (reductions_new): New.
18948 * src/LR0.c (set_state_table): Let all the states have a
18949 `reductions', even if reduced to 0.
18950 (save_reductions): Adjust.
18951 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.

18968 2001-12-27 Akim Demaille <akim@epita.fr>
18970 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
18971 * src/print.c: here.
18972 (lookaheadset, shiftset): New, used as additional storage by
18974 (print_results): Adjust.
18975 (print_shifts, print_gotos, print_errs): New, extracted from...
18976 (print_actions): here.
18977 * src/print_graph.c (print_actions): Remove dead code.
18979 2001-12-27 Akim Demaille <akim@epita.fr>
18981 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
18984 2001-12-27 Akim Demaille <akim@epita.fr>
18986 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
18987 (build_relations): Adjust.
18989 2001-12-27 Akim Demaille <akim@epita.fr>
18991 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
18994 2001-12-27 Akim Demaille <akim@epita.fr>
18996 * src/reader.c (packgram): Catch nitems overflows.
18998 2001-12-27 Akim Demaille <akim@epita.fr>
19000 * src/files.c, src/files.h (guard_obstack): Remove.
19001 * src/output.c (output): Adjust.
19002 * src/reader.c (parse_braces): New, factoring...
19003 (copy_action, copy_guard): these two which are renamed as...
19004 (parse_action, parse_guard): these.
19005 As a voluntary consequence, using braces around guards is now
19008 2001-12-27 Akim Demaille <akim@epita.fr>
19010 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
19011 * src/reader.c (symbol_list): `guard' and `guard_line' are new
19013 (symbol_list_new): Adjust.
19014 (copy_action): action_line is the first line, not the last.
19015 (copy_guard): Just as for actions, store the `action' only, not
19016 the switch/case/break flesh.
19017 Don't parse the user action that might follow the guard, let...
19018 (readgram): do it, i.e., now, there can be an action after a
19020 In other words the guard is just explicitly optional.
19021 (packgram): Adjust.
19022 * src/output.c (guards_output): New.
19023 (output_parser): Call it when needed.
19024 (output): Also free the guard and attrs obstacks.
19025 * src/files.c, src/files.h (obstack_save): Remove.
19026 (output_files): Remove.
19027 As a result, if one needs the former `.act' file, using an
19028 appropriate skeleton which requires actions and guards is now
19030 * src/main.c (main): Adjust.
19031 * tests/semantic.at: New.
19032 * tests/regression.at: Use `input.y' as input file name.
19033 Avoid 8+3 problems by requiring input.c when the test needs the

19038 * src/reader.c (symbol_list_new): Be sure to initialize all the
19041 2001-12-27 Akim Demaille <akim@epita.fr>
19043 All the hacks using a final pseudo state are now useless.
19045 * src/LR0.c (set_state_table): state_table holds exactly nstates.
19046 * src/lalr.c (nLA): New.
19047 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
19048 instead of lookaheadsp from the pseudo state (nstate + 1).
19050 2001-12-27 Akim Demaille <akim@epita.fr>
19052 * src/output.c (action_row, token_actions): Use a state_t instead
19053 of a integer, and nlookaheads instead of the following state's

19060 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
19061 (conflicts_print, print_reductions): Use a state_t instead of an
19062 integer when referring to a state.
19063 As much as possible, depend upon nlookaheads, instead of the
19064 `lookaheadsp' member of the following state (since lookaheads of
19065 successive states are successive, the difference between state n + 1
19066 and n served as the number of lookaheads for state n).
19067 * src/lalr.c (add_lookback_edge): Likewise.
19068 * src/print.c (print_core, print_actions, print_state)
19069 (print_results): Likewise.

19079 Add plenty of `static'.
19081 2001-12-27 Akim Demaille <akim@epita.fr>
19083 * src/output.c (prepare): Drop the muscle `ntbase' which
19084 duplicates ntokens.
19085 * src/bison.simple: Formatting/comment changes.
19086 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
19087 is an undocumented synonym.
19089 2001-12-22 Akim Demaille <akim@epita.fr>
19091 * src/output.c (output_table_data): Change the prototype to use
19092 `int' for array ranges: some invocations do pass an int, not a
19094 Reported by Wayne Green.
19096 2001-12-22 Akim Demaille <akim@epita.fr>
19098 Some actions of web2c.y are improperly triggered.
19099 Reported by Mike Castle.
19101 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
19102 * tests/regression.at (Web2c): Rename as...
19103 (Web2c Report): this.
19104 (Web2c Actions): New.
19106 2001-12-22 Akim Demaille <akim@epita.fr>
19108 Reductions in web2c.y are improperly reported.
19109 Reported by Mike Castle.
19111 * src/conflicts.c (print_reductions): Fix.
19112 * tests/regression.at (Web2c): New.
19114 2001-12-18 Akim Demaille <akim@epita.fr>
19116 Some host fail on `assert (!"foo")', which expands to
19117 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
19118 Reported by Nelson Beebee.
19120 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
19121 `#define it_succeeded 0' and `assert (it_succeeded)'.
19123 2001-12-17 Marc Autret <autret_m@epita.fr>
19125 * src/bison.simple: Don't hard code the skeleton line and filename.
19126 * src/output.c (output_parser): Rename 'line' as 'output_line'.
19127 New line counter 'skeleton_line' (skeleton-line muscle).

19131 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
19132 YYDEBUG must be defined to a nonzero value.
19134 * src/bison.simple (yytname): Do not assume that the user defines
19135 YYDEBUG to a properly parenthesized expression.
19137 2001-12-17 Akim Demaille <akim@epita.fr>
19139 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
19140 nlookaheads is a new member.
19142 * src/lalr.h (nlookaheads): Remove this orphan declaration.
19143 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
19146 2001-12-17 Akim Demaille <akim@epita.fr>
19148 * src/files.h, src/files.c (open_files, close_files): Remove.
19149 * src/main.c (main): Don't open/close files, nor invoke lex_free,
19151 * src/reader.c (reader): Do it.
19153 2001-12-17 Akim Demaille <akim@epita.fr>
19155 * src/conflicts.c (print_reductions): Formatting changes.
19157 2001-12-17 Akim Demaille <akim@epita.fr>
19159 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
19160 (flush_reduce): New.
19161 (resolve_sr_conflict): Adjust.
19163 2001-12-17 Akim Demaille <akim@epita.fr>
19165 * src/output.c (output_obstack): Be static and rename as...
19166 (format_obstack): this, to avoid any confusion with files.c's
19168 * src/reader.h (muscle_obstack): Move to...
19169 * src/output.h: here, since it's defined in output.c.
19171 2001-12-17 Akim Demaille <akim@epita.fr>
19173 * src/output.c (action_row, save_column, default_goto)
19174 (sort_actions, matching_state, pack_vector): Better variable
19177 2001-12-17 Akim Demaille <akim@epita.fr>
19179 * src/output.c: Various formatting changes.
19181 2001-12-17 Akim Demaille <akim@epita.fr>
19183 * src/files.c (output_files): Free the output_obstack.
19184 * src/main.c (main): Call print and print_graph conditionally.
19185 * src/print.c (print): Work unconditionally.
19186 * src/print_graph.c (print_graph): Work unconditionally.
19187 * src/conflicts.c (log_resolution): Output only if verbose_flag.
19189 2001-12-16 Marc Autret <autret_m@epita.fr>
19191 * src/output.c (actions_output): Fix. When we use %no-lines,
19192 there is one less line per action.
19194 2001-12-16 Marc Autret <autret_m@epita.fr>
19196 * src/bison.simple: Remove a useless #line directive.
19197 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
19198 * src/output.c (get_lines_number): New.
19199 (output_parser): Adjust, now takes care about the lines of a
19201 Fix line numbering.
19202 (actions_output): Computes the number of lines taken by actions.
19203 (output_master_parser): Insert new skeleton which is the name of
19204 the output parser file name.
19206 2001-12-15 Marc Autret <autret_m@epita.fr>
19208 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
19210 2001-12-15 Marc Autret <autret_m@epita.fr>
19212 * src/output.c (output_gram): Keep track of the hairy one.
19214 2001-12-15 Akim Demaille <akim@epita.fr>
19216 Make `make distcheck' work.
19218 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
19219 system.h which uses libgettext.h.
19221 2001-12-15 Akim Demaille <akim@epita.fr>
19223 * src/nullable.c (set_nullable): Useless rules must be skipped,
19224 otherwise, since we range over their symbols, we might look at a
19225 nonterminal which no longer ``exists'', i.e., it is not counted in
19226 `nvars', hence we overflow our arrays.
19228 2001-12-15 Akim Demaille <akim@epita.fr>
19230 The header can also be produced directly, without any obstack!
19233 * src/files.c, src/files.h (defines_obstack): Remove.
19234 (compute_header_macro): Global.
19235 (defines_obstack_save): Remove.
19236 * src/reader.c (parse_union_decl): No longer output to
19237 defines_obstack: its content can be found in the `stype' muscle
19239 (output_token_translations): Merge into...
19240 (symbols_output): this.
19242 (symbols_save): this.
19244 * src/output.c (header_output): New.
19247 2001-12-15 Akim Demaille <akim@epita.fr>
19249 * src/reader.c (parse_union_decl): Instead of handling two obstack
19250 simultaneously, use one to define the `stype' muscle, and use the
19251 value of the latter to fill defines_obstack.
19252 (copy_comment): Remove.
19253 (copy_comment2): Work for a single obstack.
19255 (copy_comment): this.
19257 2001-12-15 Akim Demaille <akim@epita.fr>
19259 * src/lex.c, src/lex.h (xgetc): No longer static.
19260 * src/reader.c (parse_union_decl): Revamp.
19262 2001-12-15 Akim Demaille <akim@epita.fr>
19264 Still making progress in separating Bison into (i) input, (ii)
19265 process, (iii) output: now we can directly output the parser file
19266 without using table_obstack at all.
19268 * src/files.c, src/files.h (table_obstack): Bye bye.
19269 (parser_file_name): New.
19270 * src/files.c (compute_output_file_names): Compute it.
19271 * src/output.c (actions_output, output_parser)
19272 (output_master_parser): To a file instead of an obstack.
19274 2001-12-15 Akim Demaille <akim@epita.fr>
19276 Attach actions to rules, instead of pre-outputting them to
19279 * src/gram.h (rule_t): action and action_line are new members.
19280 * src/reader.c (symbol_list): Likewise.
19281 (copy_action): Save the actions within the rule.
19282 (packgram): Save them in rule_table.
19283 * src/output.c (actions_output): New.
19284 (output_parser): Use it on `%%actions'.
19285 (output_rule_data): Don't free rule_table.
19287 (prepare): Don't save the `action' muscle.
19288 * src/bison.simple: s/%%action/%%actions/.
19290 2001-12-15 Akim Demaille <akim@epita.fr>
19292 * src/reader.c (copy_action): When --yacc, don't append a `;'
19293 to the user action: let it fail if lacking.
19294 Suggested by Arnold Robbins and Tom Tromey.
19296 2001-12-14 Akim Demaille <akim@epita.fr>
19298 * src/lex.c (literalchar): Simply return the char you decoded, non
19299 longer mess around with obstacks and int pointers.
19300 Adjust all callers.
19302 2001-12-14 Akim Demaille <akim@epita.fr>
19304 * src/lex.c (literalchar): Don't escape the special characters,
19305 just decode them, and keep them as char (before, eol was output as
19306 the 2 char string `\n' etc.).
19307 * src/output.c (output_rule_data): Use quotearg to output the
19310 2001-12-13 Paul Eggert <eggert@twinsun.com>
19312 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
19313 Do not infringe on the global user namespace when using C++.
19314 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
19315 All uses of `fprintf' and `stderr' changed.
19317 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
19319 2001-12-13 Akim Demaille <akim@epita.fr>
19321 The computation of nullable is broken: it doesn't handle empty
19324 * tests/torture.at (GNU AWK Grammar): New.
19325 * tests/sets.at (Nullable): New.
19326 * src/nullable.c (set_nullable): Instead of blindly looping over
19327 `ritems', loop over the rules, and then over their rhs's.
19329 Work around Autotest bugs.
19331 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
19332 frame, because Autotest understand lines starting with a `+' as
19333 traces from the shell. Then, they are not processed properly.
19334 Admittedly an Autotest bug, but we don't have time to wait for
19335 Autotest to catch up.
19336 * tests/regression.at (Broken Closure): Adjust to the new table
19339 * tests/sets.at: here.
19341 2001-12-13 Akim Demaille <akim@epita.fr>
19343 * src/closure.c (closure): Use nrules instead of playing tricks
19344 with BITS_PER_WORD.
19346 2001-12-13 Akim Demaille <akim@epita.fr>
19348 * src/print.c (print_actions): Output the handling of `$' as the
19349 traces do: shifting the token EOF. Before EOF was treated as a
19351 * tests/regression.at: Adjust some tests.
19352 * src/print_graph.c (print_core): Complete the set of items via
19353 closure. The next-to-final and final states are still unsatisfying,
19354 but that's to be addressed elsewhere.
19355 No longer output the rule numbers, but do output the state number.
19356 A single loop for the shifts + gotos is enough, but picked a
19357 distinct color for each.
19358 (print_graph): Initialize and finalize closure.
19360 2001-12-13 Akim Demaille <akim@epita.fr>
19362 * src/reader.c (readgram): Remove dead code, an strip useless
19364 (get_type): Remove, unused.
19366 2001-12-12 Akim Demaille <akim@epita.fr>
19368 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
19369 on that of lib/error.c.
19371 2001-12-12 Akim Demaille <akim@epita.fr>
19373 Some hosts don't like `/' in includes.
19375 * src/system.h: Include libgettext.h without qualifying the path.
19376 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
19379 2001-12-11 Marc Autret <autret_m@epita.fr>
19381 * src/output.c (output_parser): Remove useless muscle.
19383 2001-12-11 Marc Autret <autret_m@epita.fr>
19385 * src/bison.simple: Remove #line just before %%epilogue. It
19386 is now handled in ...
19387 * src/reader.c (read_additionnal_code): Add the output of a
19388 #line for the epilogue.
19390 2001-12-10 Marc Autret <autret_m@epita.fr>
19392 * src/reader.c (copy_definition): Re-use CPP-outed code which
19393 replace precedent remove.
19394 * src/bison.simple: Remove #line before %%prologue because
19395 %%input-line is wrong at this time.
19397 2001-12-10 Marc Autret <autret_m@epita.fr>
19399 * src/reader.c (symbols_output): Clean up.
19400 * src/output.c (output_gram, output): Clean up.
19402 2001-12-10 Akim Demaille <akim@epita.fr>
19404 * src/lalr.c (initialize_lookaheads): New. Extracted from...
19405 * src/LR0.c (set_state_table): here.
19406 * src/lalr.c (lalr): Call it.
19408 2001-12-10 Akim Demaille <akim@epita.fr>
19410 * src/state.h (shifts): Remove the `number' member: shifts are
19411 attached to state, hence no longer need to be labelled with a
19414 2001-12-10 Akim Demaille <akim@epita.fr>
19416 Now that states have a complete set of members, the linked list of
19417 shifts is useless: just fill directly the state's shifts member.
19419 * src/state.h (shifts): Remove the `next' member.
19420 * src/LR0.c (first_state, last_state): Remove.
19421 Adjust the callers.
19422 (augment_automaton): Don't look for the shifts that must be added
19423 a shift on EOF: it is those of the state we looked for! But now,
19424 since shifts are attached, it is no longer needed to looking
19425 merely by its id: its number.
19427 2001-12-10 Akim Demaille <akim@epita.fr>
19429 * src/LR0.c (augment_automaton): Better variable locality.
19430 Remove an impossible branch: if there is a state corresponding to
19431 the start symbol being shifted, then there is shift for the start
19432 symbol from the initial state.
19434 2001-12-10 Akim Demaille <akim@epita.fr>
19436 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
19437 only when appropriate: when insert_start_shifting_state' is not
19439 * tests/regression.at (Rule Line Numbers): Adjust.
19441 2001-12-10 Akim Demaille <akim@epita.fr>
19443 * src/LR0.c (augment_automaton): Now that all states have shifts,
19444 merge the two cases addition shifts to the initial state.
19446 2001-12-10 Akim Demaille <akim@epita.fr>
19448 * src/lalr.c (set_state_table): Move to...
19450 * src/lalr.c (lalr): Don't call it...
19451 * src/LR0.c (generate_states): do it.
19452 * src/LR0.h (first_state): Remove, only the table is used.
19454 2001-12-10 Akim Demaille <akim@epita.fr>
19456 * src/LR0.h (first_shift, first_reduction): Remove.
19457 * src/lalr.c: Don't use first_shift: find shifts through the
19460 2001-12-10 Akim Demaille <akim@epita.fr>
19462 * src/LR0.c: Attach shifts to states as soon as they are
19464 * src/lalr.c (set_state_table): Instead of assigning shifts to
19465 state, just assert that the mapping was properly done.
19467 2001-12-10 Akim Demaille <akim@epita.fr>
19469 * src/LR0.c (insert_start_shift): Rename as...
19470 (insert_start_shifting_state): this.
19471 (insert_eof_shifting_state, insert_accepting_state): New.
19472 (augment_automaton): Adjust.
19473 Better locality of the variables.
19474 When looking if the start_symbol is shifted from the initial
19475 state, using `while (... symbol != start_symbol ...)' sounds
19476 better than `while (... symbol < start_symbol ...)': If fail
19477 to see how the order between symbols could be relevant!
19479 2001-12-10 Akim Demaille <akim@epita.fr>
19481 * src/getargs.h: Don't declare `spec_name_prefix' and
19482 `spec_file_prefix', declared by src/files.h.
19483 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
19484 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
19485 * src/output.c (prepare): Adjust.
19486 * src/reader.c (symbols_output): Likewise.
19487 * src/vmsgetargs.c: Vaguely adjust, but who cares?
19489 2001-12-10 Akim Demaille <akim@epita.fr>
19491 * src/muscle_tab.c (muscle_init): NULL is a better default than
19494 2001-12-10 Akim Demaille <akim@epita.fr>
19496 * src/reader.c (reader): Calling symbols_output once is enough.
19498 2001-12-10 Akim Demaille <akim@epita.fr>
19500 Now that states have a complete set of members, the linked list of
19501 reductions is useless: just fill directly the state's reductions
19504 * src/state.h (struct reductions): Remove member `number' and
19506 * src/LR0.c (first_reduction, last_reduction): Remove.
19507 (save_reductions): Don't link the new reductions, store them in
19509 * src/lalr.c (set_state_table): No need to attach reductions to
19510 states, it's already done.
19511 * src/output.c (output_actions): No longer free the shifts, then
19512 the reductions, then the states: free all the states and their
19515 2001-12-10 Akim Demaille <akim@epita.fr>
19517 * src/options.c (OPTN, DRTV, BOTH): New.
19518 (option_table): Use them.
19520 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
19521 the job of system.h.
19522 * src/options.c: Don't include stdio.h and xalloc.h for the same
19525 2001-12-10 Akim Demaille <akim@epita.fr>
19527 * src/output.c (output, prepare): Make sure the values of the
19528 muscles `action' and `prologue' are 0-terminated.
19530 2001-12-10 Akim Demaille <akim@epita.fr>
19532 Clean up GCC warnings.
19534 * src/reader.c (copy_action): `buf' is not used.
19535 (parse_skel_decl): Be static.
19536 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
19537 * src/options.h (create_long_option_table): Have a real prototype.
19538 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
19539 (hash_delete_at): Return const void *.
19540 Adjust casts to preserve the const.
19542 2001-12-10 Akim Demaille <akim@epita.fr>
19544 * configure.in: Require 2.52g.
19545 M4 is not needed, but AUTOM4TE is.
19546 * m4/m4.m4: Remove.
19547 * tests/Makefile.am: Adjust.
19549 2001-12-10 Akim Demaille <akim@epita.fr>
19551 One structure for states is enough, even though theoretically
19552 there are LR(0) states and LALR(1) states.
19554 * src/lalr.h (state_t): Remove.
19555 (state_table): Be state_t **, not state_t *.
19556 * src/state.h (core, CORE_ALLOC): Rename as...
19557 (state_t, STATE_ALLOC): this.
19558 Add the LALR(1) members: shifts, reductions, errs.
19559 * src/LR0.c (state_table): Rename as...
19560 (state_hash): this, to avoid name clashes with the global
19562 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
19563 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
19565 2001-12-10 Akim Demaille <akim@epita.fr>
19567 Bison dumps core on bash.y.
19568 Reported by Pascal Bart.
19570 * src/warshall.c (bitmatrix_print): New.
19572 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
19573 j must be the outer loop.
19574 * tests/regression.at (Broken Closure): New.
19576 2001-12-05 Akim Demaille <akim@epita.fr>
19578 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
19580 Reported by Peter Hamorsky.
19582 2001-12-05 Akim Demaille <akim@epita.fr>
19584 * src/conflicts.c (err_table): Remove.
19585 (resolve_sr_conflict): Adjust.
19586 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
19588 (state_t.reductions, state_t.shifts): this.
19590 2001-12-05 Akim Demaille <akim@epita.fr>
19592 * src/reduce.c (reduce_grammar_tables): No longer disable the
19593 removal of useless rules via CPP but via `if (0)', so that the
19594 compiler still check the code is valid.
19595 For instance, it should have noticed `rline' no longer exists: use
19596 the `line' member of rule_t.
19597 * src/gram.c (dummy, rline): Remove, unused.
19599 2001-12-05 Akim Demaille <akim@epita.fr>
19601 * src/output.c (pack_vector): Use assert, not berror.
19602 * src/main.c (berror): Remove, unused.
19604 2001-12-05 Akim Demaille <akim@epita.fr>
19606 New experimental feature: if --verbose --trace output all the
19607 items of a state, not only its kernel.
19609 * src/print.c (print_core): If `trace_flag', then invoke closure
19610 before outputting the items of the state (print_core is no longer
19611 a correct name them).
19612 (print_results): Invoke new_closure/free_closure if needed.
19614 2001-12-05 Akim Demaille <akim@epita.fr>
19616 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
19617 * src/closure.c, src/closure.h (itemsetsize): Rename as...
19618 (nitemset): for consistency with the rest of the project.
19620 2001-12-05 Akim Demaille <akim@epita.fr>
19622 * src/closure.c (print_closure): Improve.
19623 (closure): Use it for printing input and output.
19625 2001-12-05 Akim Demaille <akim@epita.fr>
19627 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
19628 indexed by nonterminals.
19630 2001-12-05 Akim Demaille <akim@epita.fr>
19632 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
19634 * src/warshall.h: Remove accidental duplication of the content.
19636 2001-12-05 Akim Demaille <akim@epita.fr>
19638 * src/closure.c (set_fderives): De-obfuscate.

19650 * src/output.c (action_row): De-obfuscate
19651 using the good o' techniques: arrays not pointers, variable
19652 locality, BITISSET, RESETBIT etc.
19654 2001-12-05 Akim Demaille <akim@epita.fr>
19656 Pessimize the code to simplify it: from now on, all the states
19657 have a valid SHIFTS, which NSHIFTS is possibly 0.
19659 * src/LR0.c (shifts_new): Be global and move to..
19660 * src/state.c, src/state.h: here.
19661 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

19666 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
19667 * src/conflicts.c: Use it.
19668 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
19669 incorrectly ``simplified''.

19673 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
19674 using the good o' techniques: arrays not pointers, variable
19675 locality, BITISSET, RESETBIT etc.
19677 2001-12-05 Akim Demaille <akim@epita.fr>
19679 * src/state.h (SHIFT_SYMBOL): New.

19709 2001-12-05 Akim Demaille <akim@epita.fr>
19711 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

19727 * src/lalr.c (maxrhs): Move to...
19728 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
19729 * src/lalr.c (build_relations): Adjust.
19731 2001-12-05 Akim Demaille <akim@epita.fr>
19733 * src/lalr.c (transpose): Free the memory allocated to the
19734 argument, as it is replaced by the results by the unique caller.
19735 (build_relations): Merely invoke transpose: it handles the memory
19737 Improve variable locality.
19738 Avoid variables used as mere abbreviations.
19739 (compute_lookaheads): Use arrays instead of pointers.
19741 2001-12-05 Akim Demaille <akim@epita.fr>
19743 * src/lalr.c (initialize_F): Improve variable locality.
19744 Avoid variables used as mere abbreviations.

19757 2001-12-05 Akim Demaille <akim@epita.fr>
19759 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
19760 the handling of squeue.
19761 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19763 2001-12-05 Akim Demaille <akim@epita.fr>
19765 Because useless nonterminals are now kept alive (instead of being
19766 `destroyed'), we now sometimes examine them, and store information
19767 related to them. Hence we need to know their number, and adjust
19768 memory allocations.
19770 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19772 * src/LR0.c (allocate_itemsets): The memory allocated to
19773 `symbol_count' was used for two different purpose: once to count
19774 the number of occurrences of each symbol, and later reassigned to
19775 `shift_symbol', containing the symbol that can be shifted from a
19777 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19779 (new_itemsets): Allocate `shift_symbol' here.
19780 (allocate_itemsets): symbol_count includes useless nonterminals.
19781 Make room for them.
19782 (free_storage): Use `free', not `XFREE', for pointers that cannot
19785 2001-12-05 Akim Demaille <akim@epita.fr>

19793 * src/gram.c, src/gram.h (ritem_print): New.
19794 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19795 (This useless function was defined only to work around VMS linkers
19796 that can't handle compilation units with variables only).
19797 * src/reduce.c (dump_grammar): Use it to trace the construction of
19800 2001-12-04 Paul Eggert <eggert@twinsun.com>
19802 * src/bison.simple (union yyalloc): Change member names
19803 to be the same as the stack names.
19804 (yyparse): yyptr is now union yyalloc *, not char *.
19805 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19806 and may generate better code on some machines.
19807 (yystpcpy): Use prototype if __STDC__ is defined, not just
19808 if __cplusplus is defined.
19810 2001-11-30 Akim Demaille <akim@epita.fr>
19812 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19813 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
19814 Gettext doesn't compile cleanly, and dies with -Werror.
19815 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
19816 Include WARNING_CFLAGS here.
19817 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
19818 before being defined.

19822 * lib/quotearg.h (quotearg_n, quotearg_n_style):
19823 First arg is int, not unsigned.
19824 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
19825 (SIZE_MAX, UINT_MAX): New macros.
19826 (quotearg_n_options): Abort if N is negative.
19827 Avoid overflow check on hosts where size_t is 64 bits and int
19828 is 32 bits, as overflow is impossible there.
19829 Fix off-by-one typo that caused unnecessary reallocation.
19831 2001-11-29 Paul Eggert <eggert@twinsun.com>
19833 Name space cleanup in generated parser.
19835 * doc/bison.texinfo (Bison Parser): Discuss system headers
19836 and their effect on the user name space.
19838 * src/bison.simple:
19839 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19840 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19841 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19843 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
19844 on user names when possible.
19846 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
19847 Simplify test for whather <alloca.h> exists.
19849 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
19851 (<stdio.h>): Include if YYDEBUG.
19853 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
19854 ! defined (yyoverflow) && ! defined (yymemcpy).
19856 (yymemcpy, yyparse): Rename local variables as needed so that
19857 they all begin with 'yy'.
19859 (yystrlen, yystpcpy): New functions.
19861 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
19864 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
19865 instead of relying on string.h functions. Use YYSTACK_ALLOC
19866 and YYSTACK_FREE instead of malloc and free.
19868 2001-11-30 Akim Demaille <akim@epita.fr>
19870 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
19871 before their first uses.

19881 if body instead of `;' to pacify GCC's warnings.
19883 2001-11-30 Akim Demaille <akim@epita.fr>
19885 Instead of mapping the LHS of unused rules to -1, keep the LHS
19886 valid, but flag the rules as invalid.
19888 * src/gram.h (rule_t): `useful' is a new member.
19889 * src/print.c (print_grammar): Adjust.
19890 * src/derives.c (set_derives): Likewise.
19891 * src/reader.c (packgram, reduce_output): Likewise.
19892 * src/reduce.c (reduce_grammar_tables): Likewise.
19893 * tests/reduce.at (Underivable Rules, Useless Rules): New.

19902 2001-11-30 Akim Demaille <akim@epita.fr>
19904 * src/reduce.c (nonterminals_reduce): Instead of throwing away
19905 useless nonterminals, move them at the end of the symbol arrays.
19906 (reduce_output): Adjust.
19907 * tests/reduce.at (Useless Nonterminals): Adjust.
19909 2001-11-30 Akim Demaille <akim@epita.fr>

19919 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
19920 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
19922 (union yyalloc): New type.
19923 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
19924 an arbitrary restriction on hosts where size_t is wider than int.
19926 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19927 a parser stack overflow. Allocate just one block of memory for all
19928 three stacks, instead of allocating three blocks; this typically is
19929 faster and reduces fragmentation.
19931 Do not limit the number of items in the stack to a value that fits
19932 in 'int', as this is an arbitrary limit on hosts with 64-bit
19933 size_t and 32-bit int.
19935 2001-11-29 Marc Autret <autret_m@epita.fr>
19937 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
19938 of defining YYERROR_VERBOSE.
19939 [AT_DATA]: $4 is now out of C declarations in the prologue.
19941 2001-11-28 Marc Autret <autret_m@epita.fr>

19983 2001-11-28 Akim Demaille <akim@epita.fr>
19985 * src/closure.c (closure): `b' and `ruleno' denote the same value:
19988 2001-11-28 Akim Demaille <akim@epita.fr>
19990 * src/closure.c (closure): Instead of looping over word in array
19991 then bits in words, loop over bits in array.
19993 2001-11-28 Akim Demaille <akim@epita.fr>
19995 * src/closure.c (closure): No longer optimize the special case
19996 where all the bits of `ruleset[r]' are set to 0, to make the code
19999 2001-11-28 Akim Demaille <akim@epita.fr>
20001 * src/closure.c (closure): `r' and `c' are new variables, used to
20002 de-obfuscate accesses to RULESET and CORE.

20013 2001-11-28 Akim Demaille <akim@epita.fr>
20015 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
20016 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

20020 2001-11-27 Paul Eggert <eggert@twinsun.com>
20022 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
20023 use alloca when we didn't want to, and vice versa.

20106 * src/conflicts.c (conflicts_print): Don't complain at all when
20107 there are no reduce/reduce conflicts, and as many shift/reduce
20108 conflicts as expected.
20109 * tests/regression.at (%expect right): Adjust.
20111 2001-11-23 Akim Demaille <akim@epita.fr>
20113 * lib/alloca.c: Update, from fileutils.

20132 2001-11-23 Akim Demaille <akim@epita.fr>
20134 Attaching lineno to buckets is stupid, since only one copy of each

20138 * src/reader.c (rline_allocated): Remove, unused.

21738 * src/conflicts.c (conflict_report): Be sure not to append to res
21739 between two calls, which could happen if both first sprintf were
21740 skipped, but not the first cp += strlen.
21742 2001-02-08 Akim Demaille <akim@epita.fr>
21744 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
21745 New, from fileutils 4.0.37.
21746 * configure.in: Require Autoconf 2.49c. I took some time before
21747 making this decision. This is the only way out for portability
21748 issues in Bison, it would mean way too much duplicate effort to
21749 import in Bison features implemented in 2.49c since 2.13.
21750 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
21752 2001-02-02 Akim Demaille <akim@epita.fr>

21769 * src/lex.h: Rename all the tokens:
21770 s/\bENDFILE\b/tok_eof/g;
21771 s/\bIDENTIFIER\b/tok_identifier/g;
21773 Let them be enums, not #define, to ease debugging.

21781 2001-01-18 Akim Demaille <akim@epita.fr>
21783 Since we now use obstacks, more % directives can be enabled.
21785 * src/lex.c (percent_table): Also accept `%yacc',
21786 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

21791 * src/reader.c (read_declarations): Adjust.
21792 * src/files.c (open_files): Don't call `compute_base_names', don't

21796 * src/output.c (output_headers): Document the fact that this patch
21797 introduces a guaranteed SEGV for semantic parsers.
21798 * doc/bison.texinfo: Document them.
21799 * tests/suite.at: Exercise these %options.
21801 2000-12-20 Akim Demaille <akim@epita.fr>

21811 (obstack_fgrow4): New.
21813 2000-12-20 Akim Demaille <akim@epita.fr>
21815 * src/files.c (open_files): Fix the computation of short_base_name

21866 (obstack_grow_string): this.
21867 * src/output.c (output_parser): Recognize `%% actions' instead of
21869 * src/bison.s1: s/$/%% actions/.
21870 * src/bison.hairy: Likewise.
21872 2000-12-19 Akim Demaille <akim@epita.fr>
21874 * src/output.c (output_parser): Compute the `#line' lines when
21876 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

21901 * src/files.c (open_files): Yipee! We no longer need all the code

21906 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

21931 2000-11-17 Akim Demaille <akim@epita.fr>
21933 * lib/obstack.h: Formatting changes.
21934 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
21935 prevents type checking.
21936 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
21937 cast the value to (void *): assigning a `foo *' to a `void *'

21959 Use them to declare the variables which are global or local to
21962 2000-11-17 Akim Demaille <akim@epita.fr>
21964 * acconfig.h: Remove, no longer used.
21966 2000-11-07 Akim Demaille <akim@epita.fr>
21968 * src: s/Copyright (C)/Copyright/g.
21970 2000-11-07 Akim Demaille <akim@epita.fr>
21972 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
21974 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

21990 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
21991 `const' their input argument (`data' or `address').
21992 Adjust the corresponding macros to include `const' in casts.
21994 2000-11-03 Akim Demaille <akim@epita.fr>
21996 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
21997 s/PFILE1/BISON_HAIRY/.
21998 Adjust dependencies.
22000 2000-11-03 Akim Demaille <akim@epita.fr>
22002 For some reason, this was not applied.
22004 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
22005 `unlink': it's no longer used.
22007 2000-11-03 Akim Demaille <akim@epita.fr>
22009 * src/files.c (skeleton_find): New function, eved out of...

22014 Don't use `atexit'.
22016 * src/files.c (obstack_save): New function.
22017 (done): Rename as...
22018 (output_files): this.
22019 Use `obstack_save'.
22020 * src/main.c (main): Don't use `atexit' to register `done', since
22021 it no longer has to remove tmp files, just call `output_files'
22022 when there are no errors.
22024 2000-11-02 Akim Demaille <akim@epita.fr>
22026 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
22027 `unlink': it's no longer used.
22028 * src/files.h: Formatting changes.
22030 2000-11-02 Akim Demaille <akim@epita.fr>
22032 Remove the last uses of mktemp and unlink/delete.
22034 * src/files.c (fdefines, ftable): Removed.
22035 (defines_ostack, table_obstack): New.
22036 Adjust dependencies of the former into uses of the latter.
22037 * src/output.c (output_short_or_char_table, output_short_table):
22038 Convert to using obstacks.

22094 * src/reader.c (copy_comment2): Expect the input stream to be on
22095 the `/' which is suspected to open a comment, instead of being
22096 called after `//' or `/*' was read.
22097 (copy_comment, copy_definition, parse_union_decl, copy_action)
22098 (copy_guard): Adjust.
22100 2000-10-16 Akim Demaille <akim@epita.fr>
22102 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
22103 `read_signed_integer'.
22105 2000-10-16 Akim Demaille <akim@epita.fr>
22107 * src/reader.c (copy_dollar): New function.
22108 (copy_guard, copy_action): Use it.
22110 2000-10-16 Akim Demaille <akim@epita.fr>
22112 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
22113 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
22114 New files, from Fileutils 4.0.27.
22115 * src/main.c (printable_version): Remove.
22116 * src/lex.c, src/reader.c: Use `quote'.
22118 2000-10-04 Akim Demaille <akim@epita.fr>
22120 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
22122 2000-10-04 Akim Demaille <akim@epita.fr>
22124 * doc/bison.texinfo: Various typos spotted by Neil Booth.
22126 2000-10-04 Akim Demaille <akim@epita.fr>
22128 When a literal string is used to define two different tokens,
22129 `bison -v' segfaults.
22130 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
22132 * tests/regression.m4: New file.
22133 Include the core of the sample provided by Piotr Gackiewicz.
22134 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
22137 2000-10-04 Akim Demaille <akim@epita.fr>
22139 * src/reader.c (parse_expect_decl): Keep `count' within the size
22143 2000-10-02 Paul Eggert <eggert@twinsun.com>
22145 * bison.s1 (yyparse): Assign the default value
22146 unconditionally, to avoid a GCC warning and make the parser a
22149 2000-10-02 Akim Demaille <akim@epita.fr>
22151 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
22154 2000-10-02 Akim Demaille <akim@epita.fr>
22156 * src/derives.c, src/print.c, src/reduce.c: To ease the
22157 translation, move some `\n' out of the translated strings.
22159 2000-10-02 Akim Demaille <akim@epita.fr>
22161 The location tracking mechanism is precious for parse error
22162 messages. Nevertheless, it is enabled only when `@n' is used in
22163 the grammar, which is a different issue (you can use it in error
22164 message, but not in the grammar per se). Therefore, there should
22165 be another means to enable it.
22167 * src/getargs.c (getargs): Support `--locations'.
22168 (usage): Report it.
22169 * src/getargs.h (locationsflag): Export it.
22170 * src/lex.c (percent_table): Support `%locations'.
22171 * src/reader.c (yylsp_needed): Remove this variable, now replaced
22172 with `locationsflag'.
22173 * doc/bison.texinfo: Document `--locations' and `%locations'.
22175 * tests/calc.m4: Test it.
22177 For regularity of the names, replace each
22178 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
22179 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
22180 In addition replace each `flag' with `_flag'.
22182 2000-10-02 Akim Demaille <akim@epita.fr>
22184 Also test parse error messages, including with YYERROR_VERBOSE.
22186 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
22188 Use it to check the computations.
22189 Use it to check `nonassoc' is honored.
22190 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
22191 `--yyerror-verbose'.
22192 (_AT_CHECK_CALC): Adjust to this option.
22193 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
22195 2000-10-02 Akim Demaille <akim@epita.fr>
22197 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22198 the latter demonstrates a flaw in the handling of non debugging
22199 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22200 was used in order to simplify:
22216 unfortunately this leads to a CPP conflict when
22217 `--name-prefix=foo' is used since it produces `#define yydebug
22220 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
22221 (YYDPRINTF): New macro.
22223 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
22225 Also test `--verbose', `--defines' and `--name-prefix'.
22227 2000-10-02 Akim Demaille <akim@epita.fr>
22229 Improve the readability of the produced parsers.
22231 * src/bison.s1: Formatting changes.
22232 Improve the comment related to the `$' mark.
22233 (yydefault): Don't fall through to `yyresume': `goto' there.
22234 * src/output.c (output_parser): When the `$' is met, skip the end
22236 New variable, `number_of_dollar_signs', to check there's exactly
22237 one `$' in the parser skeleton.
22239 2000-10-02 Akim Demaille <akim@epita.fr>
22241 * lib/xstrdup.c: New file, from the fileutils.
22242 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
22243 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
22244 instead of strlen + xmalloc + strcpy.
22245 * src/symtab.c (copys): Remove, use xstrdup instead.
22247 2000-10-02 Akim Demaille <akim@epita.fr>
22249 * src/gram.h (associativity): New enum type which replaces the
22250 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with

22252 Adjust all dependencies.
22253 * src/reader.c: Formatting changes.
22254 (LTYPESTR): Don't define it, use it as a literal in
22255 `reader_output_yylsp'.
22256 * src/symtab.h (symbol_class): New enum type which replaces the
22257 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

22266 2000-10-02 Akim Demaille <akim@epita.fr>
22268 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22269 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22270 difficult and introduced a lot of core dump. It turns out that
22271 Bison used an implementation of `xmalloc' based on `calloc', and
22272 at various places it does depend upon the initialization to 0. I
22273 have not tried to isolate the pertinent places, and all the former
22274 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
22275 someone should address this issue.
22277 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
22278 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

22372 * src/output.c (token_actions): Introduce a temporary array,
22373 YYDEFACT, that makes it possible for this function to use
22374 output_short_table.
22376 2000-10-02 Akim Demaille <akim@epita.fr>
22378 `user_toknums' is output as a `short[]' in `output.c', while it is
22379 defined as a `int[]' in `reader.c'. For consistency with the
22380 other output tables, `user_toknums' is now defined as a table of

22423 Don't define PARAMS.
22424 * src/system.h: Define PARAMS.
22425 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

22645 Change the handling of @s so that they behave exactly like $s.
22646 There is now a pseudo variable @$ (readble and writable), location
22647 of the lhs of the rule (by default ranging from the location of
22648 the first symbol of the rhs, to the location of the last symbol,
22649 or, if the rhs is empty, YYLLOC).
22651 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
22653 (yyparse): When providing a default semantic action, provide a

22656 same way you stack YYVAL.

22658 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

22684 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

23375 Revised and use multiple warnxxx functions to avoid using VARARGS1.
23376 (read_declarations): Improve the error message for
23377 an invalid character. Do not abort.
23378 (read_declarations, copy_guard, copy_action): Use
23379 printable_version to avoid unprintable characters in printed output.
23380 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.

23411 (parse_percent_token): Added % declarations as another
23412 way to specify the flags -n, -l, and -r. Also added hooks for
23413 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
23414 major changes to files.c.
23415 (lex) Retain in the incoming stream a character following
