135 * src/files.c (tr): Move to...

528 If the first m4 in $PATH is wrong, it keeps looking. Moreover, its
529 requirements for a correct m4 are stricter.
530 * m4/m4.m4: Make it a symbolic link to submodules/autoconf/m4/m4.m4.
531 * configure.ac: Update to use AC_PROG_GNU_M4.
532 Reported by Eric Blake.
534 2009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>
536 Help with updating web manual.
537 * HACKING: Incorporate instructions from gnulib/doc/README.
538 * bootstrap.conf (gnulib_modules): Add gendocs.
540 2009-04-03 Akim Demaille <demaille@gostai.com>
543 * src/parse-gram.h, src/parse-gram.c: Regen.
545 2009-04-03 Akim Demaille <demaille@gostai.com>
547 Factor %FLAG at scan level.
548 * src/parse-gram.y (PERCENT_DEBUG, PERCENT_ERROR_VERBOSE): Token
549 definitions and associated rules, replaced by....
550 (PERCENT_FLAG): this new token type, and rule.
551 * src/scan-gram.l (RETURN_PERCENT_FLAG): New.
552 Use it for %debug and %error-verbose.

569 2009-04-03 Akim Demaille <demaille@gostai.com>
571 Treat %error-verbose as %define error_verbose.
572 This allows to pass -Derror_verbose on the command line. Better
573 yet, it allows to pass -Derror_verbose=$(ERROR_VERBOSE), with
574 ERROR_VERBOSE being defined as false or true.
575 * data/bison.m4 (b4_percent_define_if_define): Instead of relying
576 on b4_percent_define_ifdef, for does not check the defined value,
577 but only whether the symbol is defined, rely on
578 b4_percent_define_flag_if, so that a value of "false" is processed
580 If not defined, define the flag to "false".
581 (b4_error_verbose_if): New.
582 * data/glr.c, data/lalr1.cc, data/yacc.c: Use it instead of
583 b4_error_verbose_flag.
584 * src/getargs.h, src/getargs.c (error_verbose_flag): Remove.
585 * src/output.c (prepare): Don't output it.
586 * src/parse-gram.y (%error-verbose): Treat as %define error_verbose.

591 Reported by Akim Demaille at
592 <http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html>
593 and discussed again starting at
594 <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
595 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
596 because location information is bogus.
597 Use angle brackets to delimit fake file name because square brackets
598 look like underexpanded m4. Choose a better fake file name.
599 Use negative line numbers.
600 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
601 * src/location.c (location_print): If line for a boundary is negative,
602 only print that boundary's file name.
603 * src/location.h: Document that.
604 * tests/skeletons.at (%define Boolean variables: invalid skeleton
605 defaults): Update output.
607 2009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>
609 Pacify ./configure --enable-gcc-warnings.
610 * Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS) because many files
611 in lib won't compile with it.
612 * src/local.mk (src_bison_CFLAGS): Use $(WERROR_CFLAGS) here only.
614 2009-03-31 Akim Demaille <demaille@gostai.com>
616 bootstrap: --help to stdout.
617 * bootstrap (usage): Don't send --help to stderr.

642 lalr1.cc: avoid GCC 4.3 warnings.
643 GCC 4.3 now warns about "a || b && c" and asks for explicit
645 Reported by Alexandre Duret-Lutz.
646 * data/location.cc: Update copyright years.
647 (Position::operator==): Use parens to make precedence explicit.
648 Compare lines and columns first, as they are more likely to be
649 different, and they are faster to compare.
651 2009-03-26 Akim Demaille <demaille@gostai.com>
654 * gnulib: Update to latest.

670 2009-03-02 Akim Demaille <demaille@gostai.com>
672 Use locations in the variant example.
673 Yes, this obfuscates the point of this example, variants only.
674 But glr.cc cannot work (yet?) without locations. This change
675 makes it easier to use this example with glr.cc.
677 * examples/variant.yy (assert): %define it.
678 (locations): Request them.
679 (yylex): Bind the location to the stage.

695 b4_symbol_constructor_declare, as it is now done by
696 b4_public_types_define and b4_public_types_declare.
698 2009-03-02 Akim Demaille <demaille@gostai.com>

903 Fix portability issue in the test suite.
904 * tests/local.at (AT_MATCHES_CHECK): New.
905 Based on Perl instead of Sed. Sed has too many portability
906 pitfalls, not ever Sed is GNU Sed.
907 * tests/actions.at (Fix user actions without a trailing semicolon):
910 2008-12-08 Akim Demaille <demaille@gostai.com>
913 * data/README: Document glr.cc, lalr1.java, m4sugar and xslt.

936 * tests/local.mk (tests/atconfig): The rule was incorrect, but
937 remove it: now that there is no tests/Makefile.am, the top-level
938 Makefile properly updates atconfig when needed.
940 2008-12-07 Di-an Jan <dianj@freeshell.org>
942 Implement the FIXME that ends an user action with a semicolon
943 if it seems necessary.
944 * src/scan-code.l (flex rules section): Flag cpp directive from
945 any `#' to the first unescaped end-of-line. Semicolon is not
946 needed after `;', `{', '}', or cpp directives and is needed after
947 any other token (whitespaces and comments have no effect).
948 * tests/actions.at (Fix user actions without a trailing semicolon):
950 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
951 to make user actions complete statements.
952 Adjust column numbers in error messages.
953 * tests/regression.at (Fix user actions without a trailing semicolon):
954 Remove. Covered by new test.
956 2008-12-07 Akim Demaille <demaille@gostai.com>

963 Avoid compiler warning.
964 * src/output.c (muscle_insert_item_number_table): Delete unused
967 2008-12-02 Eric Blake <ebb9@byu.net>
969 Build testsuite with newer autoconf.
970 * tests/output.at (m4_expand): Don't override in newer autoconf,
971 where the underlying implementation changed.
972 * tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
973 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
974 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
975 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
976 since some of them contain unbalanced ')'.
978 2008-12-01 Akim Demaille <demaille@gostai.com>
980 Use b4_symbol for printers and destructors everywhere.
981 * data/bison.m4 (b4_symbol_action_location): New.
982 * data/c.m4 (b4_symbol_actions): Remove.
983 Adjust all callers to use by b4_symbol_foreach and the corresponding
984 b4_symbol_printer/destructor macro.
985 * data/glr.cc: Adjust.
986 * data/lalr1.java: Adjust the %destructor sanity check.
987 * src/output.c (symbol_code_props_output): Remove, we no longer
988 need the b4_symbol_printers/destructors tables.
990 2008-12-01 Akim Demaille <demaille@gostai.com>
993 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
996 2008-12-01 Akim Demaille <demaille@gostai.com>
998 Move b4_symbol based macro to bison.m4.
999 * data/lalr1.cc (b4_symbol_, b4_symbol, b4_symbol_if)
1000 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
1001 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
1002 (b4_type_foreach): Move to...
1003 * data/bison.m4: Here.
1004 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
1005 b4_symbol_value_template instead of b4_symbol_value.
1007 2008-12-01 Akim Demaille <demaille@gostai.com>
1009 b4_symbol/type_foreach.
1010 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
1013 2008-12-01 Akim Demaille <demaille@gostai.com>
1015 Use the symbol properties to output the printer/destructor for lalr1.cc.
1016 Instead of defining complex list of tuples to define various
1017 properties of the symbols, we now prefer to define symbols as
1018 "structs" in m4: using the symbol key (its number), and the
1019 property name, b4_symbol gives it value. Use this to handle
1020 destructors and printers.
1022 * src/output.c (CODE_PROP): New.
1023 (prepare_symbol_definitions): Use it to define the printer and
1024 destructor related attributes of the symbols.
1025 * data/lalr1.cc (b4_symbol_actions): Rename as...
1026 (b4_symbol_action): this.
1027 Use b4_symbol instead of 6 arguments.
1028 (b4_symbol_printer, b4_symbol_destructor): New.
1029 Use them instead of b4_symbol_actions.
1031 2008-12-01 Akim Demaille <demaille@gostai.com>
1033 Avoid capturing variables too easily.
1034 * src/muscle_tab.h (MUSCLE_INSERT_BOOL, MUSCLE_OBSTACK_SGROW): Use
1035 v__ and p__ instead of v and p.
1037 2008-12-01 Akim Demaille <demaille@gostai.com>
1039 Remove spurious empty line before syncline.
1040 * data/bison.m4 (b4_syncline): Don't output an empty line before
1043 2008-11-26 Akim Demaille <demaille@gostai.com>
1045 Convert lib/Makefile.am into lib/local.mk.
1046 The real problem is rather gnulib.mk, which itself is extracted
1047 from a Makefile.am that gnulib expects to the "recursive". The
1048 tool prefix-gnulib-mk converts such a gnulib.mk to be
1049 non-recursive. Also, some AC_SUBST variables need to be adjusted.
1051 * etc/prefix-gnulib-mk: New.
1052 * bootstrap (slurp): Use it to convert further gnulib.mk.
1053 No longer try to avoid re-creation of lib/gnulib.mk as the changes
1055 * lib/Makefile.am: Rename as...
1056 * lib/local.mk: this.
1057 Adjust to be prefixed.
1058 * Makefile.am, configure.ac: Adjust.
1059 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
1061 2008-11-26 Akim Demaille <demaille@gostai.com>
1064 * tests/local.mk (TESTSUITE_FLAGS, AUTOTEST_FLAGS): Rename as...
1065 (TESTSUITEFLAGS, AUTOTESTFLAGS): these to compy with the GCS.
1066 Reported by Eric Blake.

1116 * data/c.m4 (b4_table_define): New.
1117 * data/yacc.c: Use b4_tables_define instead of output the tables
1119 * tests/regression.at (Web2c Actions): Adjust the expected output,
1120 the order of the tables changed.
1122 2008-11-26 Akim Demaille <demaille@gostai.com>
1124 Get rid of (yy)rhs and (yy)prhs.
1125 These tables are no longer needed in the parsers, and they don't seem to
1126 be useful. They are not documented either.
1128 * src/output.c (prepare_rules): Get rid of rhs and prhs.
1129 Adjust the computation of (yy)r2.
1131 2008-11-26 Akim Demaille <demaille@gostai.com>
1133 Rule length is unsigned.
1134 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
1136 2008-11-26 Akim Demaille <demaille@gostai.com>

1139 It was no longer maintainer.
1141 * data/lalr1-split.cc: Remove.
1142 * etc/bench.pl.in (bench_fusion_parser): Remove.
1145 2008-11-26 Akim Demaille <demaille@gostai.com>
1147 Use yy* consistently.

1154 Get rid of yyrhs and yyprhs in glr.c.
1155 * data/glr.c (yyrhs, yyprhs): Remove.
1156 Instead, use the state stack and yystos.
1158 2008-11-25 Akim Demaille <demaille@gostai.com>
1161 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
1162 as an Autotest keyword.
1164 2008-11-25 Akim Demaille <demaille@gostai.com>
1166 Prefer TESTSUITE_FLAGS.
1167 TESTSUITEFLAGS is barely readable.
1169 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)

1183 2008-11-25 Akim Demaille <demaille@gostai.com>
1185 Get rid of yyrhs and yyprhs in yacc.c.
1186 They were used to get the symbol types, given a rule number, when
1187 displaying the top of the stack before a reduction. But the
1188 symbol type is available from the state stack. This has two be
1189 benefits: two tables less in the parser (making it smaller), and a
1190 more consistent use of the three stacks which will help to fuse
1193 * data/yacc.c (yyprhs, yyrhs): Remove.
1194 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
1195 (yy_reduce_print): Take yyssp as argument.
1196 Use it, together with yystos, to get the symbol type.
1197 * tests/regression.at (Web2c Report): Remove these tables from the
1200 2008-11-25 Akim Demaille <demaille@gostai.com>
1203 The point is to factor the generation of the tables across skeletons.
1204 This is language dependant.
1206 * data/c.m4 (b4_comment_): New.
1207 Should be usable to define how to generate tables independently of
1209 (b4_c_comment): New.
1210 (b4_comment): Bounce to b4_c_comment.
1211 Now support $2 = [PREFIX] for indentation.

1213 there is no comment.
1214 Indent it properly when there is one.
1215 Output the ending semicolon.
1216 (b4_table_define): Space changes.
1217 Output the ending semicolon.
1218 (b4_tables_map): New.
1219 Use it twice instead of declaring and defining the (integral)

1225 * data/lalr1.cc (b4_table_declare): New.
1226 Use it to declare the tables defined with b4_table_define.
1227 (b4_table_define): Declare a third arg to match b4_table_declare
1229 Move all the comments around invocations of b4_table_define into
1230 the invocations itselves.

1384 2008-11-15 Akim Demaille <demaille@gostai.com>
1386 Support parametric types.
1388 There are two issues to handle: first scanning nested angle
1389 bracket pairs to support types such as std::pair< std::string,
1390 std::list<std::string> > >.
1392 Another issue is to address idiosyncracies of C++: do not glue two
1393 closing angle brackets together (otherwise it's operator>>), and
1394 avoid sticking blindly a TYPE to the opening <, as it can result
1395 in '<:' which is a digraph for '['.
1397 * src/scan-gram.l (brace_level): Rename as...
1400 Implement support for complex tags.
1403 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
1404 (b4_symbol_variant): Leave space around types as parameters.
1405 * examples/variant.yy: Use nested template types and leading ::.
1406 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
1408 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
1409 * tests/c++.at: Test parametric types.
1411 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
1414 This is not sufficient, but we test at least that the make_SYMBOL
1415 interface is not affected by token.prefix. A more general test
1416 will be implemented when the support of token.prefix is generalized
1419 * tests/c++.at: One more variant test, using token.prefix.
1421 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
1423 Test the make_TOKEN interface.

1455 2008-11-15 Akim Demaille <demaille@gostai.com>
1458 * data/local.mk, etc/local.mk, examples/local.mk: Use Automake
1459 comments for the license.
1461 2008-11-15 Akim Demaille <demaille@gostai.com>
1463 Remove tests/Makefile.am.

1493 Move sc_tight_scope into maint.mk.
1494 It does not work, and I don't know how it was supposed to work: it
1495 seems to be looking for sources in the build tree. I just moved
1496 it at a better place, fixing it is still required.

1518 It used to bounce to the version in src/Makefile.am which is now
1519 part of this very Makefile.
1520 * Makefile.am, configure.ac: Adjust.
1521 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on

1523 qualify the includes with src/.
1524 * doc/Makefile.am (PREPATH): No longer include the top_builddir

1553 Remove examples/local.mk.

1575 Provide convenience constructors for locations and positions.

1577 column as arguments with default values.
1578 Always qualify initial line and column literals as unsigned.
1579 (location::location): Provide convenience constructors.
1581 2008-11-15 Akim Demaille <demaille@gostai.com>
1583 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
1585 Using template buys us nothing, and makes it uselessly complex to
1586 construct a symbol. Besides, it could not be generalized to other
1587 languages, while make_FOO would work in C/Java etc.
1589 * data/lalr1.cc (b4_symbol_): New.
1590 (b4_symbol): Use it.
1591 (b4_symbol_constructor_declaration_)
1592 (b4_symbol_constructor_definition_): Instead of generating
1593 specializations of an overloaded template function, just generate
1594 several functions whose names are forged from the token names
1595 without the token.prefix.
1596 (b4_symbol_constructor_declarations): Generate them for all the
1597 symbols, not just by class of symbol type, now that instead of
1598 specializing a function template by the token, we generate a
1599 function named after the token.
1600 (b4_symbol_constructor_specialization_)
1601 (b4_symbol_constructor_specializations): Remove.
1602 * etc/bench.pl.in: Adjust to this new API.
1604 2008-11-13 Akim Demaille <demaille@gostai.com>
1606 %define token.prefix.
1607 Provide a means to add a prefix to the name of the tokens as
1608 output in the generated files. Because of name clashes, it is
1609 good to have such a prefix such as TOK_ that protects from names
1610 such as EOF, FILE etc. But it clutters the grammar itself.
1612 * data/bison.m4 (token.prefix): Empty by default.
1613 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
1614 * data/lalr1.cc (b4_symbol): Ditto.

1618 Compute at M4 time some of the subtractions.
1619 * data/lalr1.cc (b4_subtract): New.
1620 (b4_rhs_data): Use it.
1622 2008-11-13 Akim Demaille <demaille@gostai.com>
1625 This allows the user to get the type of a token returned by yylex.
1627 * data/lalr1.cc (symbol::token): New.
1628 (yytoknum_): Define when %define lex_symbol, independently of
1630 (yytoken_number_): Move into...
1631 (symbol::token): here, since that's the only use.
1632 The other one is YYPRINT which was not officially supported
1633 by lalr1.cc, and anyway it did not work since YYPRINT uses this
1634 array under a different name (yytoknum).
1636 2008-11-13 Akim Demaille <demaille@gostai.com>
1639 * TODO (YYERRCODE): Mention the case of $undef.
1641 2008-11-13 Akim Demaille <demaille@gostai.com>
1644 * TODO (YYPRINT): New.
1646 2008-11-13 Akim Demaille <demaille@gostai.com>
1649 * data/lalr1.cc, data/yacc.c: Fix the description of the
1650 yytranslate and yytoknum tables.
1652 2008-11-13 Akim Demaille <demaille@gostai.com>
1654 Define make_symbol in the header.
1655 To reach good performances these functions should be inlined (yet
1656 this is to measure precisely). To this end they must be available
1659 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
1660 location_type with the class name.
1661 Since will now be output in the header, declare "inline".
1662 No longer use b4_symbol_constructor_specializations, but
1663 b4_symbol_constructor_definitions in the header.
1664 Don't call it in the *.cc file.
1666 2008-11-13 Akim Demaille <demaille@gostai.com>
1668 Define yytranslate in the header for lex_symbol.
1669 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
1670 into the header file when using %define lex_symbol.
1671 (yytranslate_): Declare inline.
1673 2008-11-13 Akim Demaille <demaille@gostai.com>
1675 Define the constructors of symbol_type in
1676 b4_symbol_constructor_definitions.
1677 The constructors are called by the make_symbol functions, which a
1678 forthcoming patch will move elsewhere. Hence the interest of
1679 putting them together.
1681 The stack_symbol_type does not need to be moved, it is used only
1684 * data/lalr1.cc: Move symbol_type and symbol_base_type
1685 constructors into...
1686 (b4_symbol_constructor_definitions): here.
1689 2008-11-13 Akim Demaille <demaille@gostai.com>
1691 Make it easier to move the definition of yytranslate_.
1692 Forthcoming changes will make it possible to use yytranslate_
1693 from outside the parser implementation file.
1695 * data/lalr1.cc (b4_yytranslate_definition): New.
1698 2008-11-13 Akim Demaille <demaille@gostai.com>
1700 Remove useless class specification.
1701 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
1702 to refer to the class name to use a type defined by the class for
1703 arguments of member functions.
1705 2008-11-13 Akim Demaille <demaille@gostai.com>
1707 Finer input type for yytranslate.
1708 This patch is debatable: the tradition expects yylex to return an int
1709 which happens to correspond to token_number (which is an enum). This
1710 allows for instance to return characters (such as '*' etc.). But this
1711 goes against the stronger typing I am trying to have with the new
1712 lex interface which return a symbol_type. So in this case, feed
1713 yytranslate_ with a token_type.
1715 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
1716 expect a token_type.
1718 2008-11-13 Akim Demaille <demaille@gostai.com>
1720 Honor lex-params in %define lex_symbol mode.
1721 * data/lalr1.cc: Use b4_lex_param.
1723 2008-11-13 Akim Demaille <demaille@gostai.com>
1726 * src/output.c (symbol_definitions_output): Rename symbol
1727 attributes type_name and has_type_name as type and has_type.
1728 * data/lalr1.cc: Adjust uses.
1730 2008-11-13 Akim Demaille <demaille@gostai.com>
1732 Use b4_type_names for the union type.
1733 The union used to compute the size of the variant used to iterate
1734 over the type of all the symbols, with a lot of redundancy. Now
1735 iterate over the lists of symbols having the same type-name.
1737 * data/lalr1.cc (b4_char_sizeof_): New.
1738 (b4_char_sizeof): Use it.
1739 Adjust to be called with a list of numbers instead of a single
1741 Adjust its caller for new-line issues.
1743 2008-11-13 Akim Demaille <demaille@gostai.com>
1745 Define the "identifier" of a symbol.
1746 Symbols may have several string representations, for instance if
1747 they have an alias. What I call its "id" is a string that can be
1748 used as an identifier. May not exist.
1750 Currently the symbols which have the "tag_is_id" flag set are
1751 those that don't have an alias. Look harder for the id.
1753 * src/output.c (is_identifier): Move to...
1754 * src/symtab.c (is_identifier): here.
1755 * src/symtab.h, src/symtab.c (symbol_id_get): New.
1756 * src/output.c (symbol_definitions_output): Use it to define "id"
1758 Remove the definition of "tag_is_id".
1759 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
1760 "tag_is_id" were used to produce code.
1761 We still use "tag" for documentation.
1763 2008-11-11 Akim Demaille <demaille@gostai.com>
1765 Locations are no longer required by lalr1.cc.
1766 * data/lalr1.cc (_b4_args, b4_args): New.
1767 Adjust all uses of locations to make them optional.
1768 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
1769 (AT_CHECK_NAMESPACE): Check the use of locations.
1770 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
1771 without locations with lalr1.cc.
1773 * tests/output.at: Check lalr1.cc with and without location
1775 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
1776 Don't use locations.
1778 2008-11-11 Akim Demaille <demaille@gostai.com>
1781 * tests/local.at (AT_FULL_COMPILE): New.
1782 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
1784 2008-11-11 Akim Demaille <demaille@gostai.com>
1786 Support parens in calc++.
1787 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
1788 * examples/calc++/test (run): Check the expected output.
1792 2008-11-11 Akim Demaille <demaille@gostai.com>
1794 Simplify lalr1.cc since %defines is mandatory.
1795 * data/lalr1.cc: Remove useless calls to b4_defines_if.
1797 2008-11-11 Akim Demaille <demaille@gostai.com>
1800 * TODO (yysyntax_error): New item.
1802 2008-11-11 Akim Demaille <demaille@gostai.com>
1805 * data/lalr1.cc: Use b4_error_verbose_if instead of #if
1808 2008-11-11 Akim Demaille <demaille@gostai.com>
1810 Support i18n of the parse error messages.
1811 * TODO (lalr1.cc/I18n): Remove.
1812 * data/lalr1.cc (yysyntax_error_): Support the translation of the
1813 error messages, as done in yacc.c.
1814 Stay within the yy* pseudo namespace.
1816 2008-11-11 Akim Demaille <demaille@gostai.com>
1819 * TODO (single stack, yysyntax_error): New.
1821 2008-11-11 Akim Demaille <demaille@gostai.com>
1823 Make it possible to return a symbol_type from yylex.
1824 * data/lalr1.cc (b4_lex_symbol_if): New.
1825 (parse): When lex_symbol is defined, expected yylex to return the
1827 * etc/bench.pl.in (generate_grammar_list): Extend to support this
1829 (bench_variant_parser): Exercise it.
1831 2008-11-11 Akim Demaille <demaille@gostai.com>
1833 Remove useless bench case.
1834 * etc/bench.pl.in (bench_variant_parser): VARIANT_DESTROY is
1837 2008-11-11 Akim Demaille <demaille@gostai.com>
1839 Improve display of directives.
1840 * etc/bench.pl.in (parse_term): Don't add useless eol.
1842 2008-11-11 Akim Demaille <demaille@gostai.com>
1844 Use string_cast in the bench.
1845 * etc/bench.pl.in (generate_grammar_list): Define and use
1848 2008-11-11 Akim Demaille <demaille@gostai.com>
1850 Replace yychar with a Boolean.
1851 * data/lalr1.cc (parse::yychar): Replace by...
1852 (parse::yyempty): this.
1854 2008-11-11 Akim Demaille <demaille@gostai.com>
1859 2008-11-11 Akim Demaille <demaille@gostai.com>
1861 Let yytranslate handle the eof case.
1862 * data/lalr1.cc (yytranslate_): Handle the EOF case.
1864 No longer expect yychar to be equal to yyeof_, rather, test the
1865 lookahead's (translated) kind.
1867 2008-11-11 Akim Demaille <demaille@gostai.com>
1869 yychar cannot be empty in yyerrlab.
1870 * TODO (yychar == yyempty_): New.
1871 * data/lalr1.cc: Remove the handling of this case.
1872 This eases forthcoming changes related to yychar and yytranslate.
1874 2008-11-11 Akim Demaille <demaille@gostai.com>
1876 Bench: syntactic sugar for %define/#define.
1877 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
1878 (&bench_push_parser, bench_variant_parser): Use this feature.
1882 2008-11-11 Akim Demaille <demaille@gostai.com>
1884 Less memory pressure on the "list" bench.
1885 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
1886 the values, to limit memory pressure.
1888 2008-11-11 Akim Demaille <demaille@gostai.com>
1890 Introduce make_symbol.
1891 make_symbol provides a means to construct a full symbol (kind,
1892 value, location) in a single shot. It is meant to be a Symbol
1893 constructor, parameterized by the symbol kind so that overloading
1894 would prevent incorrect kind/value pairs. Unfortunately
1895 parameterized constructors do not work well in C++ (unless the
1896 parameter also appears as an argument, which is not acceptable),
1897 hence the use of a function instead of a constructor.
1899 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1900 (b4_symbol_constructor_declarations)
1901 (b4_symbol_constructor_specialization_)
1902 (b4_symbol_constructor_specializations)
1903 (b4_symbol_constructor_definition_)
1904 (b4_symbol_constructor_definitions): New.
1905 Use them where appropriate to generate declaration, declaration of
1906 the specializations, and implementations of the templated
1907 overloaded function "make_symbol".
1908 (variant::variant): Always define a default ctor.
1909 Also provide a copy ctor.
1910 (symbol_base_type, symbol_type): New ctor overloads for value-less
1912 (symbol_type): Now public, so that functions such as yylex can use
1915 2008-11-11 Akim Demaille <demaille@gostai.com>
1917 Inform m4 whether a tag is a valid id.
1918 * src/output.c (is_identifier): New.
1919 (symbol_definitions_output): Use it to define tag_is_id.
1920 But maybe this should be done at m4 level?
1922 2008-11-11 Akim Demaille <demaille@gostai.com>
1924 Test 214 was failing: it greps with a pattern containing [ ]*
1925 which obviously meant to catch spaces and tabs, but contained only
1926 spaces. Tabulations in sources are a nuisance, so to simplify the
1927 matter, get rid of all the tabulations in the Java sources. The
1928 other skeletons will be treated equally later.
1930 * data/java.m4, data/lalr1.java: Untabify.
1931 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1932 tabulations are no longer generated.
1934 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
1936 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
1937 * configure.ac: Adjust usage.
1938 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1939 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1940 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).

1944 Workaround Java's ``code too large'' problem for parser tables
1945 in most cases, by using one function per initialization.
1946 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
1947 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
1948 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_
1949 yyprhs_, yyrline_, yytranslate_table_): Use b4_integral_parser_table.

1956 * NEWS: Document them.
1958 General Java skeleton improvements.
1959 * configure.ac (gt_JAVACOMP): Request target of 1.4, which allows
1960 using gcj < 4.3 in the testsuite, according to comments in
1961 gnulib/m4/javacomp.m4.
1962 * data/java.m4 (stype, parser_class_name, lex_throws, throws,
1963 location_type, position_type): Remove extraneous brackets from
1964 b4_percent_define_default.
1965 (b4_lex_param, b4_parse_param): Remove extraneous brackets from
1966 m4_define and m4_define_default.
1967 * data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
1968 which marks the end of user code with appropriate syncline, like all
1969 the other skeletons.
1970 (b4_user_post_prologue): Add. Don't silently drop.
1972 (parse): Inline yylex.
1973 * doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
1974 (%{...%}): Fix typo of %code imports.
1975 * tests/java.at (AT_JAVA_COMPILE): Add "java" keyword.
1977 Support annotations on parser class with %define annotations.

1994 Move constants for token names to Lexer interface.
1995 * data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.
1996 * data/java.m4 (b4_token_enum): Indent for move to Lexer interface.

2037 including those that don't have a type-name.
2038 (symbol_definitions_output): Define "is_token" and
2040 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
2041 type-name, now that they are defined too in b4_type_names.

2058 Avoid trailing spaces.
2059 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
2060 * data/lalr1.cc: Don't indent before rule and symbol actions, as
2061 they can be empty, and anyway this incorrectly indents the first

2068 2008-11-10 Akim Demaille <demaille@gostai.com>
2070 Use "enum" for integral constants.

2112 Change the handling of the symbols in the skeletons.
2113 Before we were using tables which lines were the symbols and which
2114 columns were things like number, tag, type-name etc. It is was
2115 difficult to extend: each time a column was added, all the numbers had
2116 to be updated (you asked for colon $2, not for "tag"). Also, it was
2117 hard to filter these tables when only a subset of the symbols (say the
2118 tokens, or the nterms, or the tokens that have and external number
2119 *and* a type-name) was of interest.
2121 Now instead of monolithic tables, we define one macro per cell. For
2122 instance "b4_symbol(0, tag)" is a macro name which contents is
2123 self-decriptive. The macro "b4_symbol" provides easier access to
2126 * src/output.c (type_names_output): Remove.
2127 (symbol_numbers_output, symbol_definitions_output): New.
2128 (muscles_output): Call them.
2129 (prepare_symbols): Define b4_symbols_number.

2138 2008-11-10 Akim Demaille <demaille@gostai.com>
2141 * src/output.c (muscles_output): New, extracted from...

2152 * examples/variant.yy: Formatting changes.
2155 2008-11-10 Akim Demaille <demaille@gostai.com>

2170 2008-11-10 Akim Demaille <demaille@gostai.com>
2172 Add %precedence support.
2173 Unfortunately it is not possible to reuse the %prec directive. This
2174 is because to please POSIX, we do not require to end the rules with a
2175 semicolon. As a result,
2179 is ambiguous: either a rule which precedence is that of baz, or a rule,
2180 and then a declaration of the precedence of the token baz.

2308 2008-11-09 Akim Demaille <demaille@gostai.com>
2310 Rely on the state stack to display reduction traces.
2311 To display rhs symbols before a reduction, we used information
2312 about the rule reduced, which required the tables yyrhs and
2313 yyprhs. Now use rely only on the state stack to get the same

2442 Add "%define assert" to variants.
2443 This is used to help the user catch cases where some value gets
2444 ovewritten by a new one. This should not happen, as this will
2447 Unfortunately this uncovered a bug in the C++ parser itself: the
2448 lookahead value was not destroyed between two calls to yylex. For
2449 instance if the previous lookahead was a std::string, and then an int,
2450 then the value of the std::string was correctly taken (i.e., the
2451 lookahead was now an empty string), but std::string structure itself
2454 This is now done in variant::build(other&) (which is used to take the
2455 value of the lookahead): other is not only stolen from its value, it
2456 is also destroyed. This incurs a new performance penalty of a few
2457 percent, and union becomes faster again.
2459 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

2740 In order to make it easy to perform benchmarks to ensure that
2741 there are no performance loss, lalr1.cc is forked into
2742 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2745 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2746 exercized by the test suite, the user must install a symbolic link
2747 from lalr1.cc to it.
2749 Instead of having three stacks (state, value, location), use a
2750 stack of triples. This considerably simplifies the code (and it
2751 will be easier not to require locations as currently does the C++
2752 parser), and also gives a 10% speedup according to
2753 etc/bench (probably mainly since memory allocation is done once
2754 instead of three times).
2756 Another motivation is to make it easier to destruct properly
2757 semantic values: now that they are bound to their state (hence
2758 symbol type) it will be easier to call the appropriate destructor.
2760 These changes should probably benefit the C parser too.
2762 * data/lalr1.cc: Copy as...
2763 * data/lalr1-fusion.cc: this new file.
2764 (b4_rhs_value, b4_rhs_location): New definitions overriding those
2766 (state_stack_type, semantic_stack_type, location_stack_type)
2767 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
2768 (data_type, stack_type, yystack_): New.
2769 (YYLLOC_DEFAULT, yypush_): Adjust.
2770 (yyerror_range): Now based on data_type, not location_type.
2772 2008-11-03 Akim Demaille <demaille@gostai.com>
2774 Push the state, value, and location at the same time.
2775 This is needed to prepare a forthcoming patch that fuses the three
2778 * data/lalr1.cc (parser::yypush_): New.
2779 (parser::yynewstate): Change the semantics: instead of arriving to
2780 this label when value and location have been pushed, but yystate
2781 is to be pushed on the state stack, now the three of them must
2782 have been pushed before. yystate still must be the new state.
2783 This allows to use yypush_ everywhere instead of individual
2784 handling of the stacks.
2786 2008-11-03 Akim Demaille <demaille@gostai.com>
2788 Prefer references to pointers.
2789 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
2790 definition to use references instead of pointers.
2791 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
2792 Take the value and location as references.
2795 2008-11-03 Akim Demaille <demaille@gostai.com>
2797 stack::size instead of stack::height.
2798 * data/lalr1.cc (stack::height): Rename as...
2799 (stack::size): this.
2800 Fix the output type.
2803 2008-11-03 Akim Demaille <demaille@gostai.com>
2805 Use variants to support objects as semantic values.
2806 This patch was inspired by work by Michiel De Wilde. But he used
2807 Boost variants which (i) requires Boost on the user side, (ii) is
2808 slow, and (iii) has useless overhead (the parser knows the type of
2809 the semantic value there is no reason to duplicate this
2810 information as Boost.Variants do).
2812 This implementation reserves a buffer large enough to store the
2813 largest objects. yy::variant implements this buffer. It was
2814 implemented with Quentin Hocquet.
2816 * src/output.c (type_names_output): New.
2817 (output_skeleton): Invoke it.
2818 * data/c++.m4 (b4_variant_if): New.
2819 (b4_symbol_value): If needed, provide a definition for variants.
2820 * data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
2821 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
2822 (b4_char_sizeof, yy::variant): New.
2823 (parser::parse): If variants are requested, define
2824 parser::union_type, parser::variant, change the definition of
2825 semantic_type, construct $$ before running the user action instead
2826 of performing a default $$ = $1.
2827 * examples/variant.yy: New.
2828 Based on an example by Michiel De Wilde.
2830 2008-11-03 Akim Demaille <demaille@gostai.com>
2832 Parameterize the extraction of semantic values.
2833 To make future changes easier, no longer rely on ".TYPE" being the
2834 way to get a semantic value.
2836 * data/c.m4 (b4_symbol_value): New.
2838 * data/c++.m4, data/yacc.c: Use it.
2839 * data/glr.c: Use b4_symbol_value.
2843 2008-11-03 Akim Demaille <demaille@gostai.com>
2845 Prepare easier M4 changes.
2846 * data/lalr1.cc: Use escaped [] instead of literals to prepare

2866 2008-11-02 Joel E. Denny <jdenny@ces.clemson.edu>
2868 Say %language is experimental.
2869 We're thinking of extending it's effect on output file naming. See the
2871 <http://lists.gnu.org/archive/html/bison-patches/2008-10/msg00003.html>.
2872 * NEWS: Say it's experimental.

2948 * src/files.c (compute_file_name_parts): When the user specifies
2949 --output but not --file-prefix, extract the directory prefix from the
2950 file prefix not from the grammar file name. This affects the location

3214 (EXTRA_DIST): Remove GNUmakefile, handled by Gnulib. Add maint.mk,
3215 .prev-version, and .version.
3216 * NEWS (2.3b+): Rename to...
3217 (?.?): ... this because we're dropping the "+" version naming scheme,
3218 but, in general, we still can't be sure of our next release name.
3219 * bootstrap: Add a quick hack to remove from .gitignore the
3220 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile

3254 Fix some .gitignore and .cvsignore problems.
3255 * bootstrap (insert_sorted_if_absent): Replace all uses with...
3256 (insert_vc_ignore): ... this new function, which prepends `/' to all
3257 .gitignore entries before passing them to insert_sorted_if_absent.
3258 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
3259 .cvsignore files are maintained even though Bison developers run
3260 bootstrap while using Git.
3261 * .cvsignore (*.patch *.log log patches applied): Remove, apparently

3282 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
3283 Add comments explaining these issues in more detail.

3369 Update to the current gnulib CVS repository, and fix trigraph handling
3371 * bootstrap: Update gnulib CVS repository URL.
3372 (symlink_to_dir): Encapsulate the code that guarantees the destination
3373 directory exists into...
3374 (check_dst_dir): ... this new function, and...
3375 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
3376 fail when copying files into lib/uniwidth/.
3377 * src/output.c (prepare_symbols): When writing yytname muscles, where
3378 symbol names will be encoded in C-string literals, tell quotearg to
3379 escape trigraphs. This used to be the default in gnulib.
3380 * tests/regression.at (Token definitions): Because of the change in
3381 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
3382 escapes trigraphs in symbol names. Thus, yytname no longer has
3383 trigraphs unnecessarily doubly escaped. Update test case output.
3384 Extend test case to be sure Bison's own error messages will no longer
3385 have trigraphs in symbol names unnecessarily escaped once.

3400 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
3401 consistency. Update the -g and -x entries now that they take
3402 arguments. Use brackets to indicate optional arguments.
3403 * src/getargs.c (usage): Explain the relationship between arguments of
3404 long and short options more completely. Document --defines and -d
3405 separately since the former takes an argument but, for POSIX Yacc, the
3407 (short_options): Let -W take an optional argument like --warnings.

3425 Fix the handling of $opt which resulted in all the argument to be
3426 considered as optional.

4159 * data/push.c: ... to here and compute them from the value of the
4160 %define variable push_pull.
4161 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
4162 parsing requests here...
4163 * data/yacc.c: ... hack this to switch to push.c any time
4164 b4_use_push_pull_flag or the %define variable push_pull is set. This
4165 will go away when we mv push.c yacc.c.
4166 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
4167 push parsing is not supported since unused %define variables are

4205 indent 2 spaces, not 1.
4207 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
4209 Pacify ./configure --enable-gcc-warnings.
4210 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
4211 `char const *' instead of `char *'.
4212 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
4213 local variable `sep'.
4215 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
4217 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
4219 * src/print-xml.c: Prefer "const" after types; that's more consistent.
4220 (xml_printf): Indent just 1 space for level.
4221 (e_char, xlate_char): Remove.
4222 (xml_escape_string): Rewrite to avoid undefined behavior (used
4223 storage that was freed from the stack).

4275 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
4276 Bruno Haible <bruno@clisp.org>
4278 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
4279 and is a script that invokes bison. Tighten the code. Add comments.
4281 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

4289 defaults): Rename to...
4290 (%define Boolean variables: invalid skeleton defaults): ... this and
4293 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
4295 In impure push mode, don't allow more than one yypstate to be allocated
4296 since multiple impure parsers would corrupt yynerrs.
4297 * data/push.c (yypstate_allocated): New static global variable
4299 (yypull_parse): If yypstate_new returns 0, don't report it as memory
4300 exhaustion if yypstate_allocated is 1, but still return 2.
4301 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
4302 already 1. Otherwise, set it to 1.
4303 (yypstate_delete): Set it to 0.
4304 * tests/push.at (Push Parsing: Multiple impure instances): New test
4307 2007-08-17 Bob Rossi <bob@brasko.net>

4378 Get rid of broken %no-parser, -n, and --no-parser implementation and
4380 * TODO: Don't mention them.
4381 * doc/bison.1: Likewise.
4382 * doc/bison.texinfo (Decl Summary): Likewise.
4383 (Bison Options): Likewise.
4384 (Option Cross Key): Likewise.
4385 * src/getargs.c (no_parser_flag): Remove global variable.
4386 (usage): Don't print description of -n and --no-parser.
4387 (long_options): Remove --no-parser entry here.
4388 (getargs): Remove -n case in the switch here.
4389 * src/getargs.h (no_parser_flag): Remove extern.
4390 * tests/regression.at (Web2c Actions): Remove comment that mentions
4393 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
4395 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
4396 name user variables starting with `yy'. Just pass NULL instead of a
4397 dummy local &yylval to yypush_parse.
4398 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
4401 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
4403 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
4404 true since it's then always used regardless of whether yyoverflow is
4405 defined. Reported by Christian Burger at
4406 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
4407 * THANKS: Add Christian Burger.
4409 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4410 node names: say "Decl Summary" not "Bison Declaration Summary".
4412 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
4414 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
4415 determine whether this function has already complained about an invalid
4416 value for a %define boolean variable, don't check whether Bison has
4417 ever examined the value. As written, the check was a tautology.
4418 Instead, record and check for this complaint using a separate muscle.
4420 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
4422 Fix push parsing memory leak reported by Brandon Lucia at
4423 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
4424 * THANKS: Add Brandon Lucia.
4425 * data/push.c (yypstate_delete): Free the stack if it was reallocated
4426 but the parse never completed and thus freed it.
4427 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
4428 * tests/testsuite.at: Include push.at.
4429 * test/push.at: New.
4430 (Push Parsing: Memory Leak for Early Deletion): New test case.
4432 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
4434 Improve handling of multiple S/R conflicts in the same state and of S/R
4435 conflicts involving multiple reductions.
4436 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
4437 set for a state here or Bison will abort if it is reassigned on a
4438 later conflicted reduction in the same state.
4439 Similarly, don't finalize and assign the solved conflicts report here
4440 or it will be lost if it is reassigned on a later conflicted reduction
4442 (set_conflicts): Instead, assign them both here after all S/R conflicts
4443 in the state have been fully examined.
4444 * src/print.c (shift_set): Rename to...
4445 (no_reduce_set): ... this.
4446 (print_reductions): Update for rename, and add %nonassoc error action
4447 tokens to no_reduce_set so that, when printing the first remaining
4448 reduction on an error action token, the reduction is enclosed in
4450 (print_results): Update for rename.
4451 * tests/conflicts.at (Solved conflicts report for multiple reductions
4452 in a state): New test case.
4453 (%nonassoc error actions for multiple reductions in a state): New test
4456 * src/main.c (main): Don't depend on C99 features.
4458 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
4460 * build-aux/.cvsignore: Add compile.
4461 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
4464 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
4466 * bootstrap (slurp): Create target directories that don't exist.
4467 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
4469 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4471 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
4473 * closure.c (closure): Likewise.
4474 * state.h (reductions): Comment sorting of rules.
4475 (state): Comment sorting of items.
4477 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
4479 Fix C++ test cases after recent Gnulib changes. Discussed starting at
4480 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
4481 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
4482 definition in order to avoid Gnulib headers since we don't use config.h
4484 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
4485 rather than AT_DATA so that config.h is included.
4487 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
4489 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
4490 instead of fprintf. Guard these functions with #if YYDEBUG instead of
4491 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
4492 and so that YYFPRINTF is guaranteed to be defined here.
4494 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4496 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
4498 (muscle_percent_define_check_values): ... this more helpful function.
4499 Again, it's not used yet, but it will be.
4500 * src/muscle_tab.h: Likewise.
4502 Improve some comments in parser table construction.
4503 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
4504 (generate_states): Don't mention ruleset, which is internal to closure.
4505 * src/closure.c (closure): Explain sorting of core and itemset, which
4506 is required for this function to behave correctly.
4507 * src/closure.h (closure): Mention sorting.
4509 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
4511 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4512 move the check for disabled transitions to an aver since conflict
4513 resolution hasn't happened yet.
4515 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4516 labels a state as inconsistent just because it has error transitions.
4517 The original form of this check appeared in revision 1.1 of lalr.c,
4518 which was committed on 1991-12-21. Now (at least), changing the
4519 consistency label on such a state appears to have no useful effect in
4520 any of the places it is examined, which I enumerate below. The key
4521 point to understanding each item in this enumeration is that a state
4522 with an error transition is labelled consistent in the first place only
4523 if it has no rules, so the check cannot matter for states that have
4524 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4525 to try to identify its conflicts, and a state must have *rules* to have
4526 conflicts. (2) Labelling a state as inconsistent will affect how
4527 action_row sets the default *rule* for the state. (3) Labelling a
4528 state as inconsistent will cause build_relations to add lookback edges
4529 to *rules* in that state.
4530 * src/state.h (struct state): Word the comment for member consistent
4533 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
4535 Don't depend on C99 features.
4536 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
4537 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
4538 * src/reader.c (check_and_convert_grammar): Fix for-loop.
4539 * src/state.c (state_mark_reachable_states): Fix for-loop.
4540 (state_remove_unreachable_states): Fix for-loop.
4542 Don't widen struct state with member reachable just to temporarily
4543 record reachability. Instead, use a local bitset.
4544 * src/state.h (struct state): Remove member.
4545 * src/state.c (state_new): Don't initialize it.
4546 (state_mark_reachable_states): Rename to...
4547 (state_record_reachable_states): ... this, and use bitset.
4548 (state_remove_unreachable_states): Use bitset.
4550 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
4552 * src/Makefile.am (yacc): Quote target action commands properly so
4553 that the yacc script isn't corrupt. Reported by Hans Aberg at
4554 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
4556 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
4557 the case of pure parsers. Reported by Frans Englich at
4558 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
4559 * THANKS: Add Frans Englich.
4561 * NEWS (2.3a+): In the %code entry, reference section `Bison
4562 Declaration Summary' from the manual now since the %code summary has
4564 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
4565 in the rules section must be terminated by semicolons.
4567 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
4569 Extend the front-end API for %define variables to more completely
4570 mirror the back-end. This will be useful in the future.
4571 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
4572 Update comments to mention the new front-end counterparts of these
4574 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code
4575 for muscle_string_decode and muscle_location_decode.
4576 (muscle_string_decode): New static function.
4577 (muscle_location_decode): Use MUSCLE_COMMON_DECODE.
4578 (muscle_percent_define_get, muscle_percent_define_ifdef): New
4580 (muscle_percent_define_flag_if): Use muscle_percent_define_ifdef and

4786 Undo my 2007-02-07 change, switching back to the c-strcase module
4787 introduced in the 2007-02-03 change. Bruno Haible reported that
4788 the 2007-02-07 change would be dangerous in Turkish if we add a
4789 language whose name contains "i", since "i" is not lowercase "I"
4791 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
4792 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
4793 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
4794 * m4/.cvsignore: Remove strcase.m4.
4795 * src/getargs.c: Revert 2007-02-07 change, as follows.
4796 Include c-strcase.h.
4797 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
4799 2007-02-11 Bruno Haible <bruno@clisp.org>
4801 Enable the Java related testsuite tests when the only Java compiler
4802 found is a gcj < 4.3. Discussed at
4803 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
4804 * configure.ac (gt_JAVACOMP): Don't specify a target_version.

4812 * src/reader.c (packgram): Move translation of rule actions from the
4813 beginning of packgram to...
4814 (check_and_convert_grammar): ... here right before packgram is invoked
4815 so it's easier to write more complete comments, and remove redundant
4818 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
4820 As in semantic actions, make @$ in %initial-action, %destructor, and
4821 %printer imply %locations.
4822 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
4824 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...

4826 @$ in %destructor implies %locations,
4827 @$ in %printer implies %locations): ... these new test cases.
4829 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>

4832 now that gnulib strcase has been fixed.
4833 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
4834 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
4835 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
4836 * m4/.cvsignore: Add strcase.m4.
4837 * src/getargs.c: Revert 2007-02-03 change, as follows.
4838 Don't include c-strcase.h.
4839 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4840 strcasecmp has "unspecified behavior" outside the POSIX locale,
4841 but it works fine in practice if at least one argument is ASCII,
4842 as is the case in Bison.
4844 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
4846 * tests/java.at: Skip tests if only one of javac/java is present.
4847 Reported by Joel E. Denny.
4848 * tests/atlocal.in: Adjust copyright years.
4850 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
4852 * data/lalr1.java (Stack): Work around old verifiers that disallow
4853 access to the private fields of an inner class, from the outer class.
4854 We can make Stack's fields public because user code doesn't have access
4855 to the instance of Stack used by parse(). Reported by Paul Eggert.
4857 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4859 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4860 the right spot for these files?
4861 * bootstrap.conf (gnulib_modules): Add c-strcase.
4862 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4864 * src/getargs.c: Include c-strcase.h.
4865 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4866 to avoid unspecified behavior.
4868 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>

4876 * data/c++.m4: Adjust default definitions of %define variables.
4877 * data/java.m4: Adjust default definitions of %define variables.
4878 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
4880 * tests/input.at (Boolean %define variables): Test new behavior.

4909 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4910 at_directive_argv arguments so these no longer have to be global
4911 variables. Also, update the implementation for the following changes.
4912 (fail_for_at_directive_too_many_args,
4913 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4914 (at_directive_name): Remove as at_directive_argv[0] will be used for
4916 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4917 for the directive name.

4919 skel_lex instead of global.
4920 (INITIAL): Update directive start action for above changes.
4921 (SC_AT_DIRECTIVE_ARG): Rename to...
4922 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4923 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4924 (scan_skel): Move yylex_destroy to...
4925 (skel_scanner_free): ... here.
4926 * tests/skeletons.at (installed skeleton file name): Rename to...
4927 (installed skeleton file names): ... this.
4929 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4931 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4932 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4933 Summary" not "Directives".
4934 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4935 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4936 since the former is now the more complete one.
4937 (Prologue Alternatives): Likewise and do the same for %defines.
4938 (Table of Symbols): Add summary of %code, add summary of %define, and
4939 move full %code documentation to...
4940 (Decl Summary): ... here for consistency with other entries in these
4942 Move %define entry in order to keep this list alphabetized.
4943 Reword %define entry a little to put less emphasis on the skeleton
4944 concept, which most users shouldn't have to think about.
4946 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
4948 Adjust to recent gnulib changes.
4949 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.

4955 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
4957 Simplify implementation of unqualified %code, implement macros for
4958 uniform treatment of boolean %define flags. Document %define.

5030 Clean up %define and %code implementation in M4 some. Most
5031 importantly, rename all related macros to be in the b4_percent_define
5032 and b4_percent_code namespaces. Also, complete support for `.' in
5033 %define variable names and %code qualifiers.
5034 * data/bison.m4 (b4_check_user_names): Check for special
5035 "SKELETON-NAMESPACE(name)" macros instead of using two nested

5038 (b4_percent_define_get, b4_percent_code_get): ... these.
5039 Extend documentation with examples.
5040 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
5041 b4_percent_define_skeleton_variables and
5042 b4_percent_code_skeleton_qualifiers.
5043 Expect any value for the %define variable `foo' to be stored in the
5044 macro named `b4_percent_define(foo)'; expect any %code blocks for the
5045 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
5046 expect any unqualified %code blocks to be stored in a macro named
5047 `b4_percent_code_unqualified'.
5048 Use m4_indir so that %define variable names and %code qualifiers can
5049 contain `.', which is allowed by the grammar parser.
5050 (b4_percent_define_default): New macro to set a default value for a
5052 (m4_wrap): Update wrapped code, and fix some underquoting.
5053 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
5054 Expect grammar uses of %define variables and %code qualifiers to be
5055 defined in b4_percent_define_user_variables and
5056 b4_percent_code_user_qualifiers.
5057 * data/c++.m4: Use b4_percent_define_default rather than
5058 m4_define_default. Fix some underquoting. Skeleton usage of %define
5059 variable define_location_comparison now implies skeleton usage of
5060 %define variable filename_type.
5061 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5062 data/push.c, data/yacc.c: Update macro names.
5063 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
5066 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5068 DJGPP specific issues.
5070 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
5071 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
5073 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5075 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
5076 run parsers in all tests so that Valgrind is invoked during
5077 maintainer-check-valgrind.
5078 (Duplicate representation of merged trees): Free all semantic values.
5079 (Duplicated user destructor for lookahead): Likewise.
5081 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5083 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
5084 command-line prefix.
5085 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
5086 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
5087 miss Valgrind messages.
5088 (Exploding the Stack Size with Malloc): Likewise.
5090 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5092 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
5093 locals. Reported by Juan Manuel Guerrero at
5094 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
5095 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
5096 Fix some indentation also.
5097 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
5098 explaining this issue.
5100 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
5101 and Joel E. Denny <jdenny@ces.clemson.edu>
5103 Simplify union and prologue handling, and escape union and lex/parse
5104 params with digraphs.
5105 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
5106 values to the empty string since these are no longer guaranteed
5107 initialized by the front-end.
5108 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
5109 braces around b4_user_stype since this is no longer done by the
5111 * src/files.c, src/files.h (pre_prologue_obstack,
5112 post_prologue_obstack): Remove.
5113 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
5114 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
5115 with digraphs. This fixes lex params and parse params.
5116 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
5117 * src/output.c (prepare): Remove muscle insertion of the prologues.
5118 (output): Remove freeing of pre_prologue_obstack and
5119 post_prologue_obstack.
5120 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
5121 than prologue_augment for prologue parsing so you don't need prologue
5123 (grammar_declaration): For %union RHS, use `braceless' instead of
5124 "{...}" so that braces are already stripped and code is escaped with
5126 * src/reader.c (prologue_augment): Remove.
5127 (reader): Remove initialization of pre_prologue_obstack and
5128 post_prologue_obstack.
5129 * src/reader.h (prologue_augment): Remove.
5131 * data/c.m4: Remove stray parenthesis.
5133 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5135 Remove quotes from variables names in %define directives and from
5136 qualifiers in %code directives, and restrict the characters that are
5137 allowed in them to M4-friendly ones. For %define, continue to support
5138 the quoted form as a deprecated feature. Discussed starting at
5139 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
5140 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
5142 * doc/bison.texinfo (Prologue Alternatives): Update.
5143 (Decl Summary): In %defines entry, update mention of `%code requires'
5144 and `%code provides'.
5145 (C++ Location Values): Update %define uses.
5146 (Calc++ Parser Interface): Likewise.
5147 (Calc++ Parser): Likewise, and update `%code requires' uses.
5148 (Table of Symbols): Update %code documentation.
5149 * src/parse-gram.y (prologue_declaration): For %define variables, use
5150 `variable' instead of `STRING'.
5151 (grammar_declaration): For %code qualifiers, use `ID' instead of
5153 (variable): New nonterminal that takes an `ID' or a `STRING'.
5154 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
5156 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
5157 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
5158 (%define errors): Update %define uses.
5160 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5162 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
5163 instead of muscle_insert for %define values so that M4-special
5164 characters are replaced with digraphs.
5165 * tests/input.at (%define errors): Extend to check weird values.
5167 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5169 Instead of having skeletons declare all valid %define variables and
5170 %code qualifiers, provide macros that retrieve the associated values
5171 and build these lists automatically. Thus Bison will now warn when a
5172 variable or qualifier is not used by the skeleton in the current
5173 invocation regardless of whether it might sometimes be used by that
5174 skeleton in other invocations. Also, move all %define value macros to
5175 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
5176 form, which is replaced by %code.
5177 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
5178 (b4_check_user_names): ... this, and change the series of valid name
5179 arguments to a single list argument for names used in the skeleton
5180 similar to the existing list argument for names used in the grammar.
5181 Warn instead of complaining.
5182 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
5183 values and %code code, to format %code code properly, and to build
5184 lists of all %define variables and %code qualifiers used in the
5185 skeleton: b4_skeleton_percent_define_variables and
5186 b4_skeleton_percent_code_qualifiers.
5187 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
5189 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
5190 the skeleton names lists can finish building first. In place of
5191 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
5192 expect the lists b4_user_percent_define_variables and
5193 b4_user_percent_code_qualifiers.
5194 * data/c++.m4: Where setting default values for b4_parser_class_name,
5195 b4_location_type, b4_filename_type, b4_namespace, and
5196 b4_define_location_comparison, update their names to the
5197 b4_percent_define_ namespace.
5198 * data/glr.c: Don't use b4_check_percent_define_variables and
5199 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
5200 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
5201 (b4_parser_class_name, b4_namespace): Define these using
5202 b4_get_percent_define for parser_class_name and namespace.
5203 * data/location.cc: Use b4_get_percent_define.
5204 * data/push.c: Don't use b4_check_percent_define_variables and
5205 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
5206 * data/yacc.c: Likewise, and don't call m4_exit in
5207 b4_use_push_for_pull_if or m4_wrap code will never execute.
5208 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
5210 (muscle_grow_user_name_list): ... this for consistency with the
5211 terminology used in bison.m4.
5212 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
5213 %define variable names, and rename muscle used_percent_define_variables
5214 to user_percent_define_variables.
5215 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
5216 user_percent_code_qualifiers.
5218 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
5219 {CODE} form is no longer accepted.
5220 * tests/input.at (Reject bad %code qualifiers): Rename to...
5221 (Reject unused %code qualifiers): ... this, and update test output.
5222 (%define error): Update test output.
5224 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
5226 Check for unrecognized %define variables similar to checking for
5227 unrecognized %code qualifiers. Check for redefined %define variables.
5228 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
5230 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
5231 (b4_check_percent_define_variables): New, also wraps it.
5232 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
5233 variables using b4_check_percent_define_variables.
5234 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
5235 all those exercised in the test suite and all those listed in the
5236 `Default values' section of c++.m4. Are there others?
5237 * data/push.c, data/yacc.c: Declare no valid %define variables.
5238 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
5239 similar to muscle_find, but it works even when the muscle stores a
5241 (muscle_grow_used_name_list): New function for constructing the used
5242 name list muscles that b4_check_for_unrecognized_names requires.
5243 * src/parse-gram.y (prologue_declaration): Warn if a variable is
5244 %define'd more than once. Define the b4_used_percent_define_variables
5245 muscle with muscle_grow_used_name_list.
5246 (grammar_declaration): Abbreviate %code code with
5247 muscle_grow_used_name_list.
5248 * tests/input.at (%define errors): New.
5250 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5252 Provide warn_at, complain_at, and fatal_at function callbacks to the
5253 skeletons, and use this for %code qualifier complaints.
5254 * data/bison.m4 (b4_error_at): New, invoked by...
5255 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
5256 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
5257 @fatal_at(...@) directives.
5258 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
5259 qualifiers in b4_used_percent_code_qualifiers and to use
5261 * src/location.c, src/location.h (boundary_set_from_string): New global
5263 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
5265 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
5266 to b4_used_percent_code_qualifiers.
5267 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
5269 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
5270 (lineno): Rename to...
5271 (out_lineno): ... this so I don't misunderstand it again.
5272 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
5273 here; these newlines are in the input but not the output file.
5274 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
5275 (at_directive_perform): ... this new static function, and add handling
5276 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
5278 * tests/input.at (Reject bad %code qualifiers): Update test output with
5279 locations and extend.
5281 * tests/output.at (Output file name: [, Output file name: ]): Remove
5282 bogus comment about these tests failing.
5284 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5286 Clean up b4_check_percent_code_qualifiers a little.
5287 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
5288 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
5289 documentation and add examples.
5290 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
5293 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5295 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
5296 unreliable -- especially when they're hidden inside another macro.
5297 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
5298 data/c.m4: Remove m4_divert(-1).
5299 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5300 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
5301 m4_divert_push(0) and m4_divert_pop(0).
5302 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
5303 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
5304 pushed and popped by m4sugar, should be first on the stack.
5306 Provide warn, complain, and fatal function callbacks to the skeletons.
5307 This provides more flexibility than m4_fatal, improves the error
5308 message format, and captures messages for translation. Discussed
5310 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
5311 * data/bison.m4 (b4_error): New, invoked by...
5312 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
5313 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
5314 directives. Because these M4 macros might be called when the current
5315 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
5316 the previous removal of uses of m4_divert, which caused trouble.
5317 (b4_check_percent_code_qualifiers): Use b4_complain instead of
5318 m4_fatal to report unrecognized %code qualifiers.
5319 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
5320 push parser requests.
5321 * data/glr.c: Use b4_complain instead of m4_fatal to report
5322 non-deterministic push parser requests.
5323 Update @output usage to @output(...@) form.
5324 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
5325 report missing %defines. Update @output usage to @output(...@) form.
5326 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
5328 * src/main.c (main): Invoke skel_scanner_free.
5329 * src/scan-skel.h (skel_scanner_free): Prototype new function.
5330 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
5331 obstack_for_string from flex-scanner.h.
5332 (YY_DECL): Use to declare skel_lex static.
5333 (decode_at_digraphs): Remove; now handled in the new
5334 SC_AT_DIRECTIVE_ARG start condition.
5335 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
5337 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
5338 at_directive_argv): New static globals.
5339 (INITIAL): Use fail_for_invalid_at.
5340 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
5341 recognize the start of a generalized `@directive(...@)' form and
5343 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
5344 directive args (using the new obstack_for_string), to decode the
5345 contained @ diagraphs, and to perform the directive. It recognizes
5346 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
5348 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
5349 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
5351 (scan_skel): Initialize obstack_for_string on the first call.
5352 (skel_scanner_free): New function to free obstack_for_string.
5353 * tests/input.at (Reject bad %code qualifiers): Update test output.
5355 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
5357 Consolidate the 4 prologue alternative directives (%code, %requires,
5358 %provides, and %code-top) into a single %code directive with an
5359 optional qualifier field. Discussed at
5360 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
5361 * NEWS (2.3a+): Rewrite the existing entry for the prologue
5363 * doc/bison.texinfo (Prologue Alternatives): Update.
5364 (Decl Summary): Update to %code "requires" and %code "provides".
5365 (Calc++ Parser): Update to %code "requires".
5366 (Table of Symbols): Remove entries for %requires, %provides, and
5367 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
5368 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
5369 are replaced by b4_percent_code_provides and b4_percent_code_requires,
5370 which are skeleton-specific.
5371 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
5372 declare what %code qualifiers it supports and to complain if any other
5373 qualifiers were used in the grammar.
5374 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
5375 and b4_user_code([b4_percent_code_provides]) in place of
5376 b4_user_requires and b4_user_provides.
5377 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
5378 Add b4_user_code([b4_percent_code_top]) and
5379 b4_user_code([b4_percent_code]).
5380 Invoke b4_check_percent_code_qualifiers.
5381 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
5382 PERCENT_REQUIRES): Remove.
5383 (grammar_declaration): Remove RHS's for %code-top, %provides, and
5384 %requires. Rewrite the %code RHS as the unqualified form defining the
5385 muscle b4_percent_code. Add another RHS for the qualified %code form,
5386 which defines muscles of the form b4_percent_code_QUALIFIER and the
5387 b4_used_percent_code_qualifiers muscle.
5388 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
5389 PERCENT_REQUIRES): Remove.
5390 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
5391 %code "requires" and %code "provides".
5392 * tests/input.at (Reject bad %code qualifiers): New.
5394 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
5396 Use the new code_props interface for destructors and printers.
5397 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
5398 printer_location members, and change the type of the destructor and
5399 printer members to code_props.
5400 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
5401 symbol_printer_get, semantic_type_destructor_set,
5402 semantic_type_printer_set, default_tagged_destructor_set,
5403 default_tagless_destructor_set, default_tagged_printer_set,
5404 default_tagless_printer_set): Use code_props in arguments and return
5405 types in place of char const * and location.
5406 (symbol_destructor_location_get, symbol_printer_location_get): Remove
5407 since the locations are now contained in the return of
5408 symbol_destructor_get and symbol_printer_get.
5409 * src/output.c (symbol_destructors_output, symbol_printers_output):
5411 (symbol_code_props_output): ... this to eliminate duplicate code.
5412 (output_skeleton): Update to use symbol_code_props_output.
5413 * src/reader.c (symbol_should_be_used): Update use of
5414 symbol_destructor_get.
5415 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5416 Update uses of the various _destructor_set and _printer_set functions.
5417 * src/symtab.c: (default_tagged_destructor_location,
5418 default_tagless_destructor_location, default_tagged_printer_location,
5419 default_tagless_printer_location): Remove since we...
5420 (default_tagged_destructor, default_tagless_destructor,
5421 default_tagged_printer, default_tagless_printer): ... change the type
5422 of these to code_props.
5423 (symbol_new, semantic_type_new, symbol_destructor_set,
5424 semantic_type_destructor_set, symbol_destructor_get,
5425 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
5426 symbol_check_alias_consistency, default_tagged_destructor_set,
5427 default_tagless_destructor_set, default_tagged_printer_set,
5428 default_tagless_printer_set): Update.
5429 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
5430 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
5432 (symbol_print): Use SYMBOL_CODE_PRINT.
5434 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
5436 Use the new code_props interface for rule actions.
5437 * src/symlist.h (symbol_list): Replace action, action_location, and
5438 used members with a code_props action_props member.
5439 * src/reader.c (symbol_should_be_used, grammar_rule_check,
5440 grammar_midrule_action, grammar_current_rule_merge_set,
5441 grammar_current_rule_symbol_append, packgram): Update.
5442 * src/scan-code.h (translate_rule_action): Remove, no longer used.
5443 * src/scan-code.l (handle_action_dollar): Update.
5444 (translate_rule_action): Remove, no longer used.
5445 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
5447 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5449 Use the new code_props interface in parse-gram.y.
5450 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
5451 Update all uses of translate_* functions to use the new code_props
5452 interface and to use gram_scanner_last_string_free and
5453 code_scanner_last_string_free where possible.
5454 (grammar_declaration): symbol_list_destructor_set and
5455 symbol_list_printer_set now perform the translation, so don't do it
5456 here. Use gram_scanner_last_string_free where possible.
5457 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
5458 translate_code): Remove, no longer used.
5459 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
5460 symbol_list_printer_set): Perform code translation here rather than
5461 depending on the caller to do so.
5463 * src/symlist.h (struct symbol_list): Correct some documentation typos.
5464 * src/scan-gram.h (gram_last_string): Remove declaration.
5465 * src/scan-gram.l (last_string): Declare it static.
5467 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5469 Encapsulate code properties and related functionality for the various
5470 destructors, printers, and actions into a code_props structure and
5471 interface. This patch merely implements code_props in scan-code.h and
5472 scan-code.l. Future patches will rewrite other modules to use it.
5473 Discussed starting at
5474 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
5475 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
5476 consistently initialize const structs that have an empty location
5478 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
5479 to ensure consistency.
5480 * src/scan-code.h (code_props): New structure.
5481 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
5482 function, macro, and const global variable for initializing a
5483 code_props with no code.
5484 (code_props_plain_init, code_props_symbol_action_init,
5485 code_props_rule_action_init, code_props_translate_code): The rest of
5486 the new code_props functional interface. Among other things, the init
5487 functions set the code_props kind field so that
5488 code_props_translate_code will know whether to behave like
5489 translate_symbol_action, translate_rule_action, or translate_code.
5490 These old translate functions must remain until all other modules are
5491 updated to use the new code_props interface.
5492 (code_scanner_last_string_free): New function similar to
5493 gram_scanner_last_string_free.
5494 (code_scanner_free): Add documentation.
5495 * src/scan-code.l: Implement the new interface.
5496 (code_lex): Make it static, add a code_props* argument, and remove the
5498 (last_string): New static global similar to the one in scan-gram.l.
5499 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
5501 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
5502 code_props since Bison may one day use this information for destructors
5504 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
5505 (handle_action_dollar): Use symbol_list_n_get and set used flag
5506 directly since symbol_list_n_used_set is removed.
5507 (translate_action): Add a code_props* argument and remove the rule,
5508 action, and location arguments. Pass the code_props* on to code_lex.
5509 (translate_rule_action, translate_symbol_action, translate_code):
5510 Rewrite as wrappers around the new code_props interface.
5511 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
5512 it would eventually need to break the encapsulation of code_props.
5514 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5516 * etc/.cvsignore: New.
5518 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5520 Add maintainer-push-check to run maintainer-check using push parsing in
5521 place of pull parsing where available.
5522 * Makefile.am (maintainer-push-check): New.
5523 * data/bison.m4 (b4_use_push_for_pull_if): New.
5524 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
5525 appropriately based on their existing values.
5526 (yypush_parse): Don't print push-parser-specific diagnostics if push
5527 parsing is being used in place of pull parsing.
5528 * data/yacc.c: If push parsing should replace pull parsing, redirect to
5530 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
5531 variable, and insert b4_use_push_for_pull_flag into muscles.
5532 * tests/Makefile.am (maintainer-push-check): New.
5534 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5536 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
5537 (whether successful or failed) so that yypush_parse can be invoked
5538 again to start a new parse using the same yypstate.
5539 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
5540 check multiple yypull_parse invocations on the same yypstate. For pull
5541 mode, extend to check multiple yyparse invocations.
5542 (Exploding the Stack Size with Alloca): Extend to try with
5544 (Exploding the Stack Size with Malloc): Likewise.
5546 * tests/calc.at (Simple LALR Calculator): Don't specify
5547 %skeleton "push.c" since %push-pull-parser implies that now.
5548 * tests/headers.at (export YYLTYPE): Don't check for the push
5549 declarations. Otherwise, this test case can't be used to see if push
5550 mode can truly emulate pull mode.
5551 * tests/input.at (Torturing the Scanner): Likewise.
5552 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
5553 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
5554 AT_YACC_IF, which now includes the case of push mode since %skeleton
5555 need not be used for push mode. This will be more intuitive once
5556 push.c is renamed to yacc.c.
5558 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5560 For push mode, convert yyparse from a macro to a function, invoke yylex
5561 instead of passing a yylexp argument to yypull_parse, and don't
5562 generate yypull_parse or yyparse unless %push-pull-parser is declared.
5563 Discussed starting at
5564 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
5565 * data/bison.m4 (b4_pull_if): New.
5566 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
5567 * data/push.c: Improve M4 quoting a little.
5568 (b4_generate_macro_args, b4_parenthesize): Remove.
5569 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
5570 any time a pull parser is requested.
5571 Don't #define this as a wrapper around yypull_parse. Instead, when
5572 both push and pull are requested, make it a function that does that
5574 (yypull_parse): If there's a b4_prefix, #define this to
5575 b4_prefix[pull_parse] when both push and pull are requested.
5576 Don't define this as a function unless both push and pull are
5578 Remove the yylexp argument and hard-code yylex invocation instead.
5579 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
5581 * src/getargs.c (pull_parser): New global initialized to true.
5582 * getargs.h (pull_parser): extern it.
5583 * src/output.c (prepare): Insert pull_flag muscle.
5584 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
5585 (prologue_declaration): Set both push_parser and pull_parser = true for
5586 %push-pull-parser. Set push_parser = true and pull_parser = false for
5588 * src/scan-gram.l: Don't accept %push_parser as an alternative to
5589 %push-parser since there's no backward-compatibility concern here.
5590 Scan %push-pull-parser.
5591 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
5592 instead of %push-parser.
5593 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
5594 prototype it in the module that calls yyparse.
5595 * tests/input.at (Torturing the Scanner): Likewise.
5596 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
5598 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
5600 Update etc/bench.pl. Optimize push mode a little (the yyn change
5601 deserves most of the credit).
5602 * Makefile.am (SUBDIRS): Add etc subdirectory.
5603 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
5604 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
5605 yytoken, yyval, and yyloc declarations to...
5606 (yyparse or yypush_parse): ... here to improve performance. For
5607 yypush_parse invocations after the first, be sure to assign yyn its old
5609 (yypstate_new): Don't bother initializing the yyresult field since the
5610 initial value isn't used.
5611 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
5612 remove the #define that, in push mode, set it to yyps->NAME.
5613 * etc/Makefile.am: New.
5614 * etc/bench.pl: Remove and build it instead from...
5615 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
5616 "tests/bison" from the build directory by default rather than just
5617 invoking "bison" from $PATH.
5618 (calc_grammar): Update push parser code: don't declare yylval globally,
5619 don't define yyparse_wrapper, and don't #define yyparse.
5620 (bench_grammar): Update to check all working combinations of yacc.c,
5621 push.c, impure, pure, pull, and push.
5623 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5625 For push mode, add pull wrappers around yypush_parse.
5626 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
5627 (yypull_parse): New function wrapping yypush_parse.
5628 (yyparse): New #define wrapping yypull_parse.
5629 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
5631 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
5632 prototype yylex in the module that calls yyparse, and don't prototype
5633 yyparse there. Otherwise, the yyparse expansion won't compile.
5634 * tests/input.at (Torturing the Scanner): Likewise.
5636 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5638 Enable push parsers to operate in impure mode. Thus, %push-parser no
5639 longer implies %pure-parser. The point of this change is to move
5640 towards being able to test the push parser code by running the entire
5641 test suite as if %push-parser had been declared.
5642 * data/push.c (yypush_parse): For impure mode, remove the
5643 yypushed_char, yypushed_val, and yypushed_loc arguments.
5644 Instead, declare these as local variables initialized to the global
5645 yychar, yylval, and yylloc.
5646 For the first yypush_parse invocation only, restore the initial values
5647 of these global variables when it's time to read a token since they
5648 have been overwritten.
5649 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
5651 * tests/calc.at (Simple LALR(1) Calculator): Always declare
5652 %pure-parser along with %push-parser since this test case was designed
5653 for pure push parsers.
5654 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
5655 (AT_YACC_OR_PUSH_IF): New.
5656 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
5657 add a note that it's still wrong for some cases (as it has been for a
5659 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
5660 %push-parser no longer implies %pure-parser.
5662 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5664 Remove some unnecessary differences between the pull parser code and
5665 the push parser code. This patch enables yynerrs in push mode.
5666 * data/push.c: Reformat M4 a little.
5667 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
5668 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
5669 because push mode is on. Instead, if pure mode is on, move yynerrs
5671 (b4_declare_parser_state_variables): ... here.
5672 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
5673 to yyps->NAME so it can be used in yypush_parse.
5674 (yypush_parse): Don't omit uses of yynerrs in push mode.
5676 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5678 Fix bug such that the first pushed token's value and location are
5679 sometimes overwritten (sometimes by %initial-action) before being used.
5680 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
5681 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
5682 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
5683 more closely mimic the pull parser logic.
5684 Don't copy the pushed token to yychar, yylval, and yylloc until it's
5685 time to read a token, which is after any initialization of yylval and
5687 (gottoken): Rename label to...
5688 (yyread_pushed_token): ... for clarity and to avoid infringing on the
5691 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5693 Rearrange initialization of the parser state variables so that the
5694 skeleton doesn't have to have a copy for pull mode and another for push
5695 mode. This patch also fixes at least a bug such that yylloc was not
5696 initialized (with b4_location_initial_line and
5697 b4_location_initial_column) upon calling yypush_parse. However, that
5698 initialization now overwrites the first token's location;
5699 %initial-action assigning @$ already did the same thing, and both bugs
5700 will be fixed in a later patch.
5701 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
5702 (b4_declare_parser_state_variables): Remove initialization of yytoken,
5703 yyss, yyvs, yyls, and yystacksize.
5704 (yypstate_new): Remove initialization of some yypstate fields: yystate,
5705 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
5707 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
5708 yyps->NAME so it can be used in yypush_parse.
5709 (yyparse or yypush_parse): For yypush_parse, don't print the
5710 "Starting parse" diagnostic for invocations after the first.
5711 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
5712 yypush_parse, only do it for the first invocation.
5713 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
5714 initialization to occur in yypush_parse but only on the first
5717 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5719 * data/push.c: Add CPP guards around push parser declarations in both
5720 the header and the code file.
5721 In the code file, move the push parser declarations to the same place
5722 they appear in the header file.
5723 Clean up the M4 some, especially the inconsistent underquoting in
5724 some b4_c_function_def and b4_c_function_decl uses.
5726 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5728 Encapsulate the push parser state variables into an M4 macro so the
5729 push skeleton doesn't have to list them again for pull mode's yyparse.
5730 For push mode, remove yypush_parse's local equivalents of these
5731 variables to eliminate unnecessary copying between the two sets at
5732 run-time. This patch also fixes at least a bug related to multiple
5733 %initial-action invocations in push mode.
5734 * data/push.c (b4_declare_parser_variables): Rename to...
5735 (b4_declare_scanner_communication_variables): ... this for clarity and
5737 (b4_declare_yyparse_variables): Remove and move its contents to the one
5738 spot where it was invoked.
5739 (b4_declare_parser_state_variables): New macro containing the parser
5740 state variables required by push mode.
5741 (struct yypstate): Replace all fields but yynew with
5742 b4_declare_parser_state_variables.
5743 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
5744 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
5745 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
5746 (yyparse or yypush_parse): For yyparse in pull mode, replace local
5747 parser state variable declarations with
5748 b4_declare_parser_state_variables.
5749 Don't initialize parser state variables when calling yypush_parse since
5750 yypstate_new already does that.
5751 Invoke the user's initial action only upon the first yypush_parse
5753 Remove all code that copies between the local parser state variables
5756 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5758 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
5759 prevent a name collision in a future patch where these names will
5760 sometimes be #define'd.
5761 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
5762 since it no longer has the same name as the existing argument.
5763 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
5765 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
5766 and Joel E. Denny <jdenny@ces.clemson.edu>
5768 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
5769 that the argument is case-insensitive, and there's no `=' here.
5770 For the %skeleton entry, mention that %language is better.
5771 (Bison Options): Likewise for --language and --skeleton. Move the
5772 --skeleton entry so that the `Tuning the parser' section is sorted
5773 alphabetically on long options.
5774 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
5775 %language directive in detail here; cross-reference the %language
5776 documentation instead.
5777 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
5778 `%require "2.3b"' so that the example is always up-to-date.
5779 (Table of Symbols): Add entries for %language and %skeleton.
5780 * examples/extexi (normalize): Instead of replacing every %require
5781 argument with the current Bison version, just substitute for
5782 `@value{VERSION}'. This guarantees that we're testing what actually
5783 appears in the documentation.
5784 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
5785 rather than `@VERSION@'.
5787 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5789 * NEWS: Reword the %language news a bit, and put it earlier.
5791 * src/getargs.c (skeleton_arg): Last arg is now location const *.
5792 Rewrite to simplify the logic.
5793 (language_argmatch): Likewise.
5794 (program_name): We now own this var.
5795 * src/getargs.h (struct bison_language): Use char[] rather than
5798 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
5800 * src/complain.c (program_name): Remove decl; no longer needed.
5801 * src/main.c (program_name): Remove; now belongs to getargs.
5803 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
5805 * NEWS: Document %language.
5807 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
5809 * data/c-skel.m4, data/c++-skel.m4: New files.
5810 * data/glr.c: Complain on push parsers.
5812 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
5814 (Decl Summary): Document %language and %skeleton.
5815 (Command line): Document -L.
5817 * examples/extexi: Rewrite %require directive.
5818 * examples/calc++/Makefile.am: Pass VERSION to extexi.
5820 * src/files.c (compute_exts_from_gc): Look in language structure
5822 (compute_file_name_parts): Check whether .tab should be added.
5823 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
5824 (language, skeleton_arg, language_argmatch): New.
5825 (long_options): Add --language.
5826 (getargs): Use skeleton_arg, add -L/--language.
5827 * src/getargs.h: Include location.h.
5828 (struct bison_language, language, skeleton_arg, language_argmatch): New.
5829 * src/output.c (prepare): Pick default skeleton from struct language.
5830 Don't dispatch C skeletons here.
5831 * src/parse-gram.y (PERCENT_LANGUAGE): New.
5832 (prologue_declaration): Add "%language" rule, use skeleton_arg.
5833 * src/scan-gram.l ("%language"): New rule.
5835 * tests/calc.at: Test %skeleton and %language.
5836 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
5837 (AT_GLR_IF): Look for %skeleton "glr.cc".
5838 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
5839 (AT_YACC_IF): Reject %language.
5841 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5843 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5844 since it wasn't used; only the typedef name 'semantic_type' is needed.
5845 Also, omit trailing white space.
5847 * bootstrap: Sync from coreutils.
5848 (gnulib_extra_files): Add build-aux/announce.gen.
5849 (slurp): Adjust .gitignore files like .cvsignore files.
5850 * build-aux/announce-gen: Remove from CVS, since bootstrap
5853 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5855 Make %push-parser imply %pure-parser. This fixes several bugs; see
5856 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5857 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5859 * data/push.c: Don't bother testing b4_push_if when deciding whether
5860 to expand b4_declare_parser_variables globally.
5861 (yypush_parse): Likewise in here.
5863 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5864 (yy_reduce_print): Reformat M4 for readability.
5866 2006-12-15 Bob Rossi <bob@brasko.net>
5867 and Joel Denny <jdenny@ces.clemson.edu>
5869 * data/push.c (yypstate): Add typedef, and update all uses of
5870 struct yypstate to just yypstate.
5871 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5873 2006-12-14 Bob Rossi <bob@brasko.net>
5875 * data/push.c (yypush_parse): Declare prototype regardless of
5878 2006-12-14 Bob Rossi <bob@brasko.net>
5880 * data/push.c (yyparse): Remove the prototype and the #define when in
5883 2006-12-13 Bob Rossi <bob@brasko.net>
5885 * data/push.c (yypstate_init): Rename to...
5886 (yypstate_new): ... this and use b4_c_function_def.
5887 (yypstate_delete): New.
5888 (yypush_parse): Change parameters yynval and yynlloc to be const.
5889 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5890 yypstate_delete functions.
5892 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5894 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5895 strange test case titles. Reported by Bob Rossi.
5897 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5899 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5900 of potential ambiguities in GLR grammers.
5902 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5904 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5905 `bison ', use m4_index instead of m4_substr since chopping up a string
5906 containing M4-special characters causes problems here.
5908 Fix a couple of bugs related to special characters in user-specified
5909 file names, and make it easier for skeletons to compute output file
5910 names with the same file name prefix as Bison-computed output file
5912 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5913 b4_parser_file_name and b4_spec_defines_file instead of
5914 @output_parser_name@ and @output_header_name@, which are now redundant.
5915 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5916 b4_parser_file_name, b4_spec_defines_file, and the new
5917 @basename(FILENAME@) instead of @output_parser_name@ and
5918 @output_header_name@, which inappropriately escaped the file names as
5920 * src/files.c (all_but_ext): Remove static qualifier.
5921 (compute_output_file_names): Move `free (all_but_ext)' to...
5922 (output_file_names_free): ... here since all_but_ext is needed later.
5923 * src/files.h (all_but_ext): Extern.
5924 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5925 exactly what MUSCLE_INSERT_STRING used to do.
5926 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5927 characters are escaped properly.
5928 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5930 For pkgdatadir muscle, maintain previous functionality by using
5931 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5932 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5933 digraphs would never be expanded. Hopefully no one has M4-special
5934 characters in his Bison installation path.
5935 * src/scan-skel.l: Don't parse @output_header_name@ and
5936 @output_parser_name@ anymore since they're now redundant.
5937 In @output, use decode_at_digraphs.
5938 Parse a new @basename command that invokes last_component.
5939 (decode_at_digraphs): New.
5940 (BASE_QPUTS): Remove unused.
5941 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
5942 (Output file name): New tests.
5944 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
5946 Warn about output files that are generated by the skeletons and that
5947 conflict with other output files.
5948 * data/glr.c: Don't generate the header file here when glr.cc does.
5949 * src/files.c (file_names, file_names_count): New static globals.
5950 (compute_output_file_names): Invoke output_file_name_check for files
5951 not generated by the skeletons and remove existing checks.
5952 (output_file_name_check): New function that warns about conflicting
5954 (output_file_names_free): Free file_names.
5955 * src/files.h (output_file_name_check): Declare.
5956 * src/scan-skel.l: Invoke output_file_name_check for files generated by
5958 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
5959 (Conflicting output files): New tests.
5961 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5963 * doc/bison.texinfo: Fix a couple of typos.
5965 2006-12-08 Bob Rossi <bob@brasko.net>
5967 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
5969 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
5971 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
5972 (yypush_parse): Rename yypvars argument to yyps and remove redundant
5974 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
5975 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
5977 2006-12-07 Bob Rossi <bob@brasko.net>
5978 and Joel Denny <jdenny@ces.clemson.edu>
5980 * data/push.c (yypvarsinit): Change return type from void* to struct
5981 yypvars*. No longer cast to void* on return.
5982 (struct yypvars): Remove yylen since it need not be remembered between
5983 yypushparse invocations.
5984 (yypushparse): Don't copy between yylen and pv->yylen.
5986 2006-12-05 Bob Rossi <bob@brasko.net>
5988 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
5989 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
5990 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
5991 (struct yypvars): Remove b4_declare_parser_variables.
5992 (yypvarsinit): Remove init code for removed variables.
5993 (global scope): Do not declare b4_declare_parser_variables if
5995 (yypushparse): Add b4_declare_parser_variables.
5996 Init new local variables, and remove init code for removed
5999 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
6000 and yyparse for other modes.
6001 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
6002 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
6003 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
6004 (AT_PURE_LEX_IF): True if pure or push parser.
6006 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
6008 Document Yacc prologue alternatives and default %destructor's and
6009 %printer's as experimental. Don't mention Java yet. Discussed at
6010 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.

6028 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
6029 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
6030 all but one occurrence of %name-prefix.
6031 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
6032 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
6033 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
6034 occurrence of each of %file-prefix and %output. Add check for %defines
6036 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
6037 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
6038 Remove the `=' from %output.
6040 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
6042 Don't escape $ in test case titles since Autoconf 2.61 now does that
6044 * tests/actions.at (Default %printer and %destructor are not for error
6045 or $undefined): Here.
6046 (Default %printer and %destructor are not for $accept): Here.
6047 * tests/input.at (Invalid $n and @n): Here.
6049 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
6051 Rename <!> to <>. Discussed starting at
6052 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.

6061 * tests/actions.at (Default tagless %printer and %destructor,
6062 Default tagged and per-type %printer and %destructor,
6063 Default %printer and %destructor are not for error or $undefined,
6064 Default %printer and %destructor are not for $accept,
6065 Default %printer and %destructor for mid-rule values): Update.
6066 * tests/input.at (Default %printer and %destructor redeclared,
6067 Unused values with default %destructor): Update.
6069 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>

6082 grammar is maintained with Bison's highest standards.
6083 * src/getargs.c: Fix some typos in Doxygen comments.
6085 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
6087 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
6088 later. Reported by Paul Eggert in
6089 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
6090 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
6091 * src/scan-code.l (translate_action): Don't bother invoking
6092 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
6093 (code_scanner_free): Instead of invoking
6094 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

6102 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
6103 has been called previously for the same key.
6104 (muscle_find): Return storage instead of value so that
6105 --enable-gcc-warnings doesn't produce warnings that the return discards
6106 const. aver that the value and storage are the same since storage
6107 could potentially be NULL when value is not.
6108 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
6111 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6113 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
6114 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
6115 us a slightly cleaner distribution, and also works.
6116 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
6119 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
6120 and Paul Eggert <eggert@cs.ucla.edu>

6123 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
6124 (spec_defines_file, dir_prefix): Now char *, not const char *,
6125 since they are freed.
6126 * src/files.c: Likewise.
6127 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
6129 (tr): Now operates in-place. All uses changed.
6130 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
6132 (compute_file_name_parts, compute_output_file_names): Don't store
6133 read-only data in variables that will be freed.
6134 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
6135 src_extension, and header_extension.
6136 (output_file_names_free): New public function to free
6137 spec_verbose_file, spec_graph_file, spec_defines_file,
6138 parser_file_name, and dir_prefix.
6139 * src/getargs.c (getargs): Don't store read-only data in variables that
6141 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
6142 (which previously existed but was unused), and quotearg_free.
6143 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
6144 * src/muscle_tab.c: Likewise.
6145 (muscle_entry): Make the value char const *,
6146 and add a new storage member that is char * and can be freed.
6147 (muscle_entry_free): New private function.
6148 (muscle_init): Use it instead of free.
6149 (muscle_insert, muscle_grow): Update and use new storage member.
6150 (muscle_code_grow): Free the string passed to muscle_grow
6151 since it's not needed anymore.
6152 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
6153 add a new `char *code' member.
6154 ("{...}"): Declare semantic type as code.
6155 * src/scan-code.h (translate_rule_action):
6156 (translate_symbol_action, translate_code, translate_action): Return
6157 `char const *' rather than `char *' since external code should not free
6159 * src/scan-code.l: Likewise.
6160 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
6161 which is "{...}" in the parser.
6162 * tests/Makefile.am (maintainer-check-valgrind): Set
6163 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
6165 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
6167 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
6168 expecting a non-zero exit status sets --leak-check=summary and
6169 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
6170 this case, and we don't want to hear about it.
6172 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6174 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
6175 instead of from the template, to simplify configuration a bit.

6188 the value is a set/used mid-rule value unless
6189 --warnings=midrule-values was specified.
6190 * tests/input.at (Unused values, Unused values before symbol
6191 declarations): Run tests with and without --warnings=midrule-values.
6193 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
6194 than LIST_FREE directly.
6196 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

6215 empty subargument list. For example: `bison --warnings= parser.y'.
6217 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
6219 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
6220 the parser header file so that gcc doesn't warn.
6222 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
6224 Split the default %destructor/%printer into two kinds: <*> and <!>.

6270 Don't apply the default %destructor/%printer to an unreferenced midrule
6272 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
6273 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
6274 like $@n instead of just @n so that the default %destructor/%printer
6275 logic doesn't see them as user-defined symbols.
6276 (symbol_is_dummy): Check for both forms of the name.
6277 * src/reader.c (packgram): Remove the `$' from each midrule symbol
6278 name for which the midrule value is referenced in any action.

6309 alternative to the pre-prologue. Mentioned at
6310 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.

6368 In messages and comments, say e.g., "checked-out sources",
6369 rather than "CVS sources".
6370 (version_controlled_file): New function. Work for git as well as
6371 for CVS. Don't use grep's -q option.
6372 (slurp): Call it here, in place of CVS-specific code.
6374 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
6376 Fix testsuite for ./configure --enable-gcc-warnings:
6377 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
6378 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
6379 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
6380 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.

6421 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
6422 variable was sometimes used without being initialized. This
6423 messed up the installation of the INSTALL file in some cases.
6425 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
6427 * bootstrap (usage, main program, symlink_to_gnulib): Add option
6428 --copy. Inspired by a suggestion from Bruno Haible.
6430 2006-10-03 Jim Meyering <jim@meyering.net>
6432 * bootstrap: Undo last change to this file, since now gnulib-tool
6433 sticks with the automake default in generating dependencies.
6435 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
6437 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
6438 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
6440 * doc/bison.1: Add copyright notice.

6461 * src/print_graph.c: Include graphviz.h rather than vcg.h.
6462 (static_graph, fgraph): Remove. All uses changed to pass
6463 arguments instead of sharing a static var.
6464 (print_core, print_actions, print_state, print_graph):
6465 Output graphviz format rather than VCG format.
6466 * tests/.cvsignore: Remove *.vcg; add *.dot.
6467 * tests/output.at: Expect *.dot files, not *.vcg files.
6469 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
6470 accommodates the 2006-10-08 change.
6472 2006-10-11 Bob Rossi <bob@brasko.net>
6474 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.

6499 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
6500 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
6501 b4_define_user_cde and uses): Remove.

6511 Fix test failure reported by Tom Lane in
6512 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
6513 and try to make such failures easier to catch in the future.
6514 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
6515 that's now the caller's responsibility.
6516 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
6517 Set yychar = YYEOF if it's negative.
6518 * tests/actions.at (yylex): Abort if asked to read past EOF.

6528 Fix problems with translating English-language diagnostics.
6529 * bootstrap: Fix bug introduced in recent bootstrap changes, with
6530 respect to bison-runtime pot generation. The YY_ stuff
6531 wasn't being captured.
6532 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
6533 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
6534 * runtime-po/POTFILES.in: Add data/push.c.
6536 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
6538 Merge bootstrap changes from coreutils.
6540 2006-09-28 Jim Meyering <jim@meyering.net>
6542 Automatically generated dependencies are important even
6543 when all of the sources in a directory come from gnulib.
6544 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
6545 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
6547 2006-09-23 Jim Meyering <jim@meyering.net>
6549 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
6551 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>

6573 Remove config.h, config.hin, intl (no longer created).
6574 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
6577 Sync bootstrap from coreutils, as follows:
6579 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
6581 * bootstrap (symlink_to_gnulib): New function.
6582 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
6583 to copies-of-gnulib.
6584 (cp_mark_as_generated, slurp, gnulib_files):
6585 Avoid making a copy if it's the same as the old version.
6586 (gnulib_files): Add support for this variable (used by Bison).
6588 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6590 * src/getargs.c (usage): Rework to use conventions similar to
6591 coreutils, to make translation a bit easier and the code a bit
6592 smaller. Problem reported by Tim Van Holder.
6594 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
6596 Use some of gnulib's new modules, taken from coreutils.
6598 * bootstrap: Sync from coreutils, except add support for gnulib_files.
6599 * bootstrap.conf: New file.
6600 (gnulib_modules): Add configmake, inttypes, unistd.
6601 (XGETTEXT_OPTIONS): Add complain, complain_at,
6602 fatal, fatal_at, warn, warn_at, unexpected_end.
6603 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
6604 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
6606 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
6608 (GNULIB_AUTOCONF_SNIPPET): Remove.
6609 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
6611 * lib/.cvsignore: Add inttypes_.h.
6612 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
6613 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
6614 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
6615 no-longer-necessary initializations.
6616 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
6617 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
6618 use the unistd module.
6619 * src/system.h: Likewise.
6620 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
6621 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
6622 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
6623 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
6624 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
6625 * src/system.h: Include inttypes.h unconditionally, now that we
6626 use the inttypes module. Don't bother to include stdint.h, since
6627 inttypes.h now does that for us.
6628 (LOCALEDIR): Remove, now that we use the configmake module.
6629 * src/getargs.c: Include configmake.h.
6630 * src/main.c: Likewise.
6631 * src/output.c: Likewise.
6632 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
6633 not from $abs_top_builddir, since config.h moved.
6636 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
6637 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
6639 * src/parse-gram.y (symbol_declaration): Don't put statements
6640 before declarations; it's not portable to C89.
6641 * src/scan-code.l (handle_action_at): Likewise.
6643 * src/scan-code.l: Always initialize braces_level; the old code
6644 left it uninitialized and therefore had undefined behavior.
6646 Don't attempt to redefine 'assert', since it runs afoul of
6647 systems where standard headers (mistakenly) include <assert.h>.
6648 Instead, define and use our own alternative, called 'aver'.
6649 * src/reader.c: Don't include assert.h, since we no longer
6651 * src/scan-code.l: Likewise.
6652 * src/system.h (assert): Remove, replacing with....
6653 (aver): New function, taking a bool arg. All uses changed.
6654 * src/tables.c (pack_vector): Ensure that aver arg is bool,
6655 not merely an integer.
6657 2006-09-15 Bob Rossi <bob@brasko.net>
6659 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
6660 * data/c.m4 (YYPUSH): New.

6663 * src/getargs.h (push_parser): New declaration.
6664 * src/output.c (prepare): Add macro insertion of `push_flag'.
6665 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
6666 (prologue_declaration): Parse %push-parser.
6667 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
6668 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
6669 list of removed lines from the traces observed.
6670 (AT_CHECK_CALC_LALR): Added push parser tests.
6672 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
6674 * NEWS: Version 2.3a.
6675 * configure.ac (AC_INIT): Likewise.
6677 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
6678 "#define YYSTYPE int" that caused "make maintainer-check" to fail
6679 due to header ordering dependencies. I don't know why the #define
6682 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
6683 runtime cost when YYDEBUG is not defined, and so that some tests
6684 that used to fail now work. Problem and initial suggestion by
6686 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
6687 * data/glr.cc (b4_parser_class_name):
6688 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
6689 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
6690 (yydebug_) [YYDEBUG]: New member.
6691 (yycdebug_): Now defined only if YYDEBUG.
6692 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
6693 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
6694 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
6696 (debug_stream, set_debug_stream, debug_level, set_debug_level):
6697 Define only if YYDEBUG.
6698 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
6700 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
6701 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
6702 AT_CHECK_CALC_GLR_CC that are working now.
6704 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
6706 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
6707 We don't need them in glr.cc, and glr.c defines them.
6708 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
6709 assumes that defining it to anything is the same as defining
6710 it to 1. Problem reported by Paolo Bonzini.
6712 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
6714 * data/c.m4 (b4_null, b4_case): Define.
6715 * src/output.c (prepare_symbols): Use b4_null.
6716 (user_actions_output): Use b4_case.
6718 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
6720 * data/glr.c (b4_shared_declarations): Put start-header first,
6721 before any #includes that we generate, so that feature-test
6722 macros work. Problem reported by Michael Deutschmann in
6723 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
6724 * data/lalr1.cc: Likewise.
6725 * doc/bison.texinfo (Prologue): Document that feature-test macros
6726 should be defined before any Bison declarations.
6727 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
6728 that depend on location.hh after, not before, Bison decls, since
6729 we now include location.hh after the first user prologue.
6731 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
6732 Sander Brandenburg in
6733 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
6734 Also, fix minor white space and comment issues.
6735 (Prologue): Mention that it's better to define feature-test macros
6736 before Bison declarations. Problem reported by Michael Deutschmann.
6738 * README-cvs: Fix typo: "&" should be "&&". Problem reported
6740 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
6741 This adjusts to recent gnulib changes.
6743 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>

6751 %destructor/%printer description.
6752 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
6753 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6754 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
6755 list node contains a semantic type.
6756 * src/symtab.c, src/symtab.h: Extend with a table that associates
6757 semantic types with their %destructor's and %printer's.
6758 (semantic_type_from_uniqstr, semantic_type_get,
6759 semantic_type_destructor_set, semantic_type_printer_set): New functions
6760 composing the public interface of that table.
6761 (symbol_destructor_get, symbol_destructor_location_get,
6762 symbol_printer_get, symbol_printer_location_get): If there's no
6763 per-symbol %destructor/%printer, look up the per-type before trying
6765 * tests/actions.at (Per-type %printer and %destructor): New test case.
6766 * tests/input.at (Default %printer and %destructor redeclared):
6767 Extend to check that multiple occurrences of %symbol-default in a
6768 single %destructor/%printer declaration is an error.
6769 (Per-type %printer and %destructor redeclared, Unused values with
6770 per-type %destructor): New test cases.
6772 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6774 Require default %destructor/%printer to be declared using
6775 %symbol-default instead of an empty symbol list, and start working on
6776 new per-type %destructor/%printer. Discussed at
6777 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
6778 * NEWS (2.3+): Add %symbol-default to example.
6779 * bison.texinfo (Freeing Discarded Symbols): Likewise.
6780 (Table of Symbols): Add entry for %symbol-default.
6781 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
6782 (generic_symlist, generic_symlist_item): New nonterminals for creating
6783 a list in which each item is a symbol, semantic type, or
6785 (grammar_declaration): Use generic_symlist in %destructor and %printer
6786 declarations instead of symbols.1 or an empty list.
6787 (symbol_declaration, precedence_declaration, symbols.1): Update actions
6788 for changes to symbol_list.
6789 * src/reader.c: Update for changes to symbol_list.
6790 * src/scan-code.l: Likewise.
6791 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
6792 * src/symlist.c, src/symlist.h: Extend such that a list node may
6793 represent a semantic type or a %symbol-default in addition to just an
6794 ordinary symbol. Add switched functions for setting %destructor's and
6796 * tests/actions.at, tests/input.at: Add %symbol-default to all default
6797 %destructor/%printer declarations.
6799 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
6801 Whether the default %destructor/%printer applies to a particular symbol
6802 isn't a question of whether the user *declares* that symbol (in %token,
6803 for example). It's a question of whether the user by any means
6804 *defines* the symbol at all (by simply using a char token, for
6805 example). $end is defined by Bison whereas any other token with token
6806 number 0 is defined by the user. The error token is always defined by
6807 Bison regardless of whether the user declares it with %token, but we
6808 may one day let the user define error as a nonterminal instead.
6809 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6810 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
6811 the meaning of "user-defined".
6812 * tests/actions.at (Default %printer and %destructor for user-declared
6813 end token): Rename to...
6814 (Default %printer and %destructor for user-defined end token): ...
6817 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
6818 computation of whether to apply the default, don't maintain a list of
6819 every Bison-defined symbol. Instead, just check for a first character
6820 of '$', which a user symbol cannot have, and check for the error token.
6822 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
6824 Don't apply the default %destructor or %printer to the error token,
6825 $undefined, or $accept. This change fits the general rule that the
6826 default %destructor and %printer are only for user-declared symbols,
6827 and it solves several difficulties that are described in the new test
6829 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
6830 * tests/actions.at (Default %printer and %destructor are not for error
6831 or $undefined, Default %printer and %destructor are not for $accept):
6834 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
6836 Allow %start after the first rule.
6837 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
6838 when parsing the first rule.
6839 (check_and_convert_grammar): Search for it here after all grammar
6840 declarations have been parsed. Skip midrules, which have dummy LHS
6842 * src/symtab.c (symbol_is_dummy): New function.
6843 * src/symtab.h (symbol_is_dummy): Declare it.
6844 * tests/input.at (%start after first rule): New test.
6846 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6848 Redo some of the previous commit: add back the ability to use
6849 non-aliased/undeclared string literals since it might be useful to
6850 those declaring %token-table.
6851 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6852 commit: don't worry about complaints from symbols_pack.
6853 * src/symtab.c (symbol_new, symbol_class_set,
6854 symbol_check_alias_consistency): Undo changes in previous commit: count
6855 each string literal as a new symbol and token, assign it a symbol
6856 number, and don't complain about non-aliased string literals.
6857 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6858 and token counts but does still set aliased tokens to the same number,
6859 symbol_pack_processor now leaves empty slots in the symbols array.
6861 * tests/regression.at (Undeclared string literal): Remove test case
6862 added in previous commit since non-aliased string literals are allowed
6864 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6865 remove unnecessary string literal declarations.
6866 * tests/sets.at (Firsts): Likewise.
6868 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6870 Don't allow an undeclared string literal, but allow a string literal to
6871 be used before its declaration.
6872 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6873 symbols_pack complained.
6874 * src/symtab.c (symbol_new): Don't count a string literal as a new
6876 (symbol_class_set): Don't count a string literal as a new token, and
6877 don't assign it a symbol number since symbol_make_alias does that.
6878 (symbol_make_alias): It's not necessary to decrement the symbol and
6879 token counts anymore. Don't assume that an alias declaration occurs
6880 before any uses of the identifier or string, and thus don't assert that
6881 one of them has the highest symbol number so far.
6882 (symbol_check_alias_consistency): Complain if there's a string literal
6883 that wasn't declared as an alias.
6884 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6885 symbol_pack asserts that every token has been assigned a symbol number
6886 although undeclared string literals have not.
6887 * tests/regression.at (String alias declared after use, Undeclared
6888 string literal): New test cases.
6889 (Characters Escapes, Web2c Actions): Declare string literals as
6891 * tests/sets.at (Firsts): Likewise.
6893 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6895 In the grammar scanner, STRING_FINISH unclosed constructs and return
6896 them to the parser in order to improve error messages.
6897 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6898 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6899 * tests/input.at (Unclosed constructs): New test case.
6900 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6903 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6906 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6908 Handle string aliases for character tokens correctly.
6909 * src/symtab.c (symbol_user_token_number_set): If the token has an
6910 alias, check and set its alias's user token number instead of its own,
6911 which is set to indicate the alias. Previously, every occurrence of
6912 the character token in the grammar overwrote that alias indicator with
6914 * tests/input.at (String aliases for character tokens): New test.
6916 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6918 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6920 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6922 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6923 to prevent failures when building on older platforms.
6924 Check for autopoint failure.
6925 Set XGETTEXT_OPTIONS to values that check for C format strings,
6926 so that translators are warned about them (this also helps
6927 prevent core dumps).
6929 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6930 function, since it simplifies our code a bit.
6932 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6933 rather than -W, so we don't get bogus warnings about sign comparisons.
6934 Add -Wpointer-arith, since that warning is useful (it reports code
6935 that does not conform to C89 and that some compilers reject).
6936 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6937 since it's no longer needed.
6939 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6941 Clean up scanners a bit.
6942 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6943 definitions so gcc won't warn when obstack_for_string is unused.
6944 * src/scan-code.l: config.h and system.h are already #include'd by
6945 scan-code-c.c, so get rid of them here.
6946 * src/scan-gram.l: Likewise.
6947 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6948 definitions rather than duplicating the rest of it.
6949 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6951 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6953 Suppress signed/unsigned comparison warnings for yycheck.
6954 * data/c.m4 (b4_safest_int_type): New macro.
6955 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6956 a signed int type, cast it to b4_safest_int_type first.
6957 * data/yacc.c: Likewise.
6958 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6961 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6963 * doc/bison.texinfo: Fix some typos.
6965 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6967 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6968 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6970 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6971 the latest gnulib does this a different way.
6972 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6973 translation was patched, so stop omitting it.
6975 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6977 Enable declaration of default %printer/%destructor. Make the parser
6978 use these for all user-declared grammar symbols for which the user does
6979 not declare a specific %printer/%destructor. Thus, the parser uses it
6980 for token 0 if the user declares it but not if Bison generates it as
6981 $end. Discussed starting at
6982 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6983 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6985 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6986 * NEWS (2.3+): Mention.
6987 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
6988 declare a %destructor for a mid-rule's semantic value. It's just
6989 impossible to declare one specific to it.
6990 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
6991 code. Describe default %destructor form.
6992 * src/parse-gram.y (grammar_declaration): Parse default
6993 %printer/%destructor declarations.
6994 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
6995 and symbol_destructor_location_get rather than accessing the destructor
6996 and destructor_location members of struct symbol.
6997 (symbol_printers_output): Likewise but for %printer's.
6998 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
7000 * src/symtab.c (default_destructor, default_destructor_location,
7001 default_printer, default_printer_location): New static global
7002 variables to record the default %destructor and %printer.
7003 (symbol_destructor_get, symbol_destructor_location_get,
7004 symbol_printer_get, symbol_printer_location_get): New functions to
7005 compute the appropriate %destructor and %printer for a symbol.
7006 (default_destructor_set, default_printer_set): New functions to set the
7007 default %destructor and %printer.
7008 * src/symtab.h: Prototype all those new functions.
7009 * tests/actions.at (Default %printer and %destructor): New test to
7010 check that the right %printer and %destructor are called, that they're
7011 not called for $end, and that $$ and @$ work correctly.
7012 (Default %printer and %destructor for user-declared end token): New
7013 test to check that the default %printer and %destructor are called for
7014 a user-declared end token.
7015 * tests/input.at (Default %printer and %destructor redeclared, Unused
7016 values with default %destructor): New tests to check related grammar
7017 warnings and errors.
7019 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
7021 Clean up handling of %destructor for the end token (token 0).
7022 Discussed starting at
7023 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
7025 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
7027 Make the skeletons consistent in how they pop the end token and invoke
7029 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
7030 state, which has token number 0, since this would invoke the
7031 %destructor for the end token.
7032 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
7033 until after shifting the end token, or else it won't be popped.
7034 * data/yacc.c (yyparse): Likewise.
7036 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
7037 it's the end token. Upon termination, destroy an unshifted lookahead
7038 even when it's the end token.
7039 * data/lalr1.cc (yy::parser::parse): Likewise.
7040 * data/yacc.c (yyparse): Likewise.
7042 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
7043 value warnings for the end token when the user gives the end token a
7046 * tests/actions.at (Printers and Destructors): Test all the above.
7048 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
7050 Update to latest gnulib and gettext versions.
7051 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
7053 (gnulib_files): Add m4/warning.m4. Don't worry about files
7054 overwritten by autopoint.
7055 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
7056 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
7058 Don't use autoreconf; instead, invoke autopoint etc. by hand,
7059 so that we can remove the intl files at a better time.
7060 (intl_files_to_remove): Remove aclocal.m4, since it gets
7061 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
7062 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
7063 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
7064 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
7065 Remove datarootdir hack; no longer needed.
7066 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
7067 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
7068 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
7070 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
7071 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
7073 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7075 * bootstrap: Adjust to today's change to gnulib-tool by invoking
7076 it with --assume-autoconf='latest-stable'.
7078 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
7080 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
7081 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
7083 * src/muscle_tab.h (muscle_grow): Replace the header comments with
7084 those from muscle_tab.c since the old ones are misleading.
7086 2006-07-13 Akim Demaille <akim@epita.fr>
7088 Support %define "KEY" {VALUE}.
7089 * src/scan-code.h, src/scan-code.l (translate_action)
7090 (translate_rule_action, translate_symbol_action, translate_code):
7091 Return char *, not const char *.
7092 * src/parse-gram.y (declaration): Rename as...
7093 (prologue_declaration): this.
7094 (string_content): Remove this nonterminal, use STRING.
7095 (braceless, content, content.opt): New nonterminal.
7097 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
7099 * src/scan-gram.l (getargs.h): Don't include it.
7101 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
7103 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
7104 rather than a for-loop that declares a local bool variable. This
7105 should work around a compatibility problem with a Cray x1e C++
7106 compiler reported by Hung Nguyen in
7107 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
7108 The for-loop was introduced in the 2004-11-17 change but I don't
7109 know why it was needed.
7111 2006-07-12 Akim Demaille <akim@epita.fr>
7113 * data/c.m4: Comment changes.
7115 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
7117 * src/complain.c (error_message, ERROR_MESSAGE): New.
7119 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
7120 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
7122 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
7124 * NEWS: Instead of %union, you can define and use your own union type
7125 YYSTYPE if your grammar contains at least one <type> tag.
7126 Your YYSTYPE need not be a macro; it can be a typedef.
7127 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
7128 (Union Decl, Decl Summary): Document this.
7129 * data/glr.c (YYSTYPE): Implement this.
7130 * data/glr.cc (YYSTYPE): Likewise.
7131 * data/lalr1.cc (YYSTYPE): Likewise.
7132 * data/yacc.c (YYSTYPE): Likewise.
7133 * src/output.c (prepare): Output tag_seen_flag.
7134 * src/parse-gram.y (declaration, grammar_declaration):
7135 Use 'union_seen' rather than 'typed' to determine whether
7136 %union has been seen, since grammars can now be typed without
7138 (symbol_declaration, type.opt, symbol_def):
7139 Keep track of whether a tag has been seen.
7140 * src/reader.c (union_seen, tag_seen): New vars.
7142 * src/reader.h (union_seen, tag_seen, typed): Likewise.
7143 * src/scan-code.l (untyped_var_seen): New variable.
7144 (handle_action_dollar): Adjust to above changes.
7145 (handle_action_dollar, handle_action_at):
7146 Improve overflow checking for outlandish numbers.
7147 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
7148 avoid new diagnostics generated by above changes.
7149 * tests/regression.at (YYSTYPE typedef): Add test to check
7150 for type tags without %union.
7152 * src/symlist.c (symbol_list_length): Return int, not unsigned
7153 int, since callers expect int. This may need to get revisited
7154 once we have proper integer overflow checking.
7156 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
7157 object is now static.
7159 * src/getargs.c (flags_argmatch): Return void, not int,
7160 to pacify ./configure --enable-gcc-warnings.
7162 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
7163 since last_string is already defined to FLEX_PREFIX (last_string).
7165 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
7167 Implement --warnings/-W.
7168 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
7170 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
7172 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
7173 (warnings_args, warnings_types): New.
7174 (getargs, short_options, long_options): Accept -W/--warnings.
7175 Sort the options by alphabetical order, upper case letter right
7176 before its lower case.
7178 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
7180 Change %merge result type clash warnings to errors. Discussed at
7181 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
7182 * src/reader.c (record_merge_function_type): Use complain_at.
7183 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7184 declared later): Update test case results.
7186 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
7188 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
7189 to be in alphabetical order.
7190 (trace_args): Spelling fixes.
7192 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
7194 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
7195 so they don't collide with user-defined macros.
7196 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
7197 this was never guaranteed, and now that we're using gnulib stdint,
7198 which defines int_fast16_t to long int, the problem is exposed.
7200 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
7202 * data/c.m4 (b4_basename): Simplify a bit, since we don't
7203 need the full POSIX semantics (and weren't implementing them
7206 Adjust to Autoconf 2.60 and today's gnulib.
7207 * bootstrap (gnulib_modules): Add stdint.
7208 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
7209 no longer copies it.
7210 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
7211 since stdint needs the former and wcwidth (which is now required
7212 by mbswidth) needs the latter.
7213 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
7214 work around a compatibility glitch between gettext 0.14.6 and
7216 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
7217 Do not check for uintptr_t, since new stdint module does the right
7219 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
7220 Add stdint.h, stdint_.h, wcwidth.h.
7221 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
7222 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
7223 stdint.m4, wchar_t.m4, wcwidth.m4.
7224 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
7225 usual order for ../lib/*.h files.
7226 (file_name_split): Use last_component, not base_name, to adjust
7228 * src/parse-gram.h: Include <strverscmp.h> in the usual order
7229 for ../lib/*.h files.
7230 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
7231 Define unconditionally, since we now assume the stdint module.
7232 * src/scan-skel.l: Include <dirname.h>.
7233 (BASE_QPUTS): Use last_component, not base_name.
7234 * src/system.h: Include <unlocked-io.h> in the usual order
7235 for ../lib/*.h files. Include <stdint.h> unconditionally,
7236 since we now use the stdint module.
7237 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
7238 HAVE_UINTPTR_T, since we now use the stdint module.
7239 (base_name): Remove decl, since files now include <dirname.h>
7242 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
7244 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
7246 * data/yacc.c, data/glr.c, data/location.cc: Use them.
7247 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
7249 * tests/calc.at: Adjust.
7251 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
7253 * data/c.m4 (b4_basename): New.
7254 (b4_syncline): Also output the location of its invocation (from
7256 (b4_user_action, b4_define_user_action, b4_user_actions)
7257 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
7258 (b4_user_stype): New.
7259 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
7261 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
7263 In the grammar file, the first column is 1 not 0 on the first line as
7264 on every other line.
7265 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
7266 * tests/input.at (Torturing the Scanner): Update output.
7268 * src/scan-gram.l (scanner_cursor): Declare it static.
7270 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
7272 In warnings, say "previous declaration" rather than "first
7274 * src/symtab.c (redeclaration): Do that here.
7275 * src/reader.c (record_merge_function_type): In the case of a result
7276 type clash, report the previous declaration rather than the very first
7277 one in the grammar file.
7278 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7279 declared later): Add a third declaration to check this behavior.
7280 * tests/input.at (Incompatible Aliases): Update output.
7282 2006-06-27 Akim Demaille <akim@epita.fr>
7284 * doc/Doxyfile.in: New.
7285 * doc/Makefile.am: Use it.
7286 * src/lalr.h, src/symtab.h: Initial doxygenation.
7288 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7290 Don't miss %merge result type warnings just because the LHS types are
7291 declared after the %merge. This continues the effort of the previous
7293 * src/reader.c (get_merge_function): Don't set the merger type yet.
7294 (record_merge_function_type): New function for setting the merger type
7295 and checking for clashes.
7296 (grammar_current_rule_merge_set): Set the location of the %merge for
7298 (packgram): Invoke record_merge_function_type for each rule now that
7299 all symbol type declarations have been parsed.
7300 * src/reader.h (merger_list.type_declaration_location): New member
7301 storing the location of the first %merge from which the type for this
7302 merging function was derived.
7303 * src/symlist.h (symbol_list.merger_declaration_location): New member
7304 storing the location of a rule's %merge, if any.
7305 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7306 declared later): New test to catch the error fixed by the above patch.
7308 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7310 Get action warnings (grammar_rule_check) right even when symbol
7311 declarations appear after the rules. Discussed at
7312 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
7314 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
7315 Don't mistake the type of $$ in a midrule to be that of its parent
7317 * src/reader.c (grammar_current_rule_end): Don't invoke
7318 grammar_rule_check yet since not all symbol declarations may have been
7320 (grammar_midrule_action): Likewise.
7321 Don't record whether the midrule's $$ has been used yet since actions
7322 haven't been translated yet.
7323 Record the midrule's parent rule and its RHS index within the parent
7325 (grammar_current_rule_action_append): Don't translate the action yet
7326 since not all symbol declarations may have been parsed yet and, thus,
7327 warnings about types for $$, $n, @$, and @n can't be reported yet.
7328 (packgram): Translate the action and invoke grammar_rule_check now that
7329 all symbol declarations have been parsed.
7330 * src/scan-code.l (handle_action_dollar): Now that this is invoked
7331 after parsing the entire grammar file, the symbol list here in the case
7332 of a midrule is actually the midrule's empty RHS, so reference its
7333 parent rule's RHS where necessary.
7334 On the other hand, now that you can already know it's a midrule, you
7335 aren't forced to think $$ has the same type as its parent rule's $$.
7336 (handle_action_at): In the case of a midrule, reference the parent rule
7338 * src/symlist.c (symbol_list_new): Initialize new midrule-related
7340 (symbol_list_length): Now that this is invoked after all rules have
7341 been parsed, a NULL symbol (rather than a NULL symbol list node)
7342 terminates a rule. symbol_list_print already does this correctly.
7343 * src/symlist.h (symbol_list.midrule_parent_rule,
7344 symbol_list.midrule_parent_rhs_index): New members so that midrules can
7345 remember their relationships with their parents.
7346 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
7347 fixed by the above patch.
7348 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
7350 (Unused values): ... this old test case and...
7351 (Unused values before symbol declarations): ... this new test case.
7352 This one is the same as `Unused values' except that all symbol
7353 declarations appear after the rules in order to catch the rest of the
7354 errors fixed by the above patch.
7356 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7359 * src/reader.c (current_rule): Declare it static since it's no longer
7360 used outside this file.
7361 (grammar_current_rule_action_append): Remove redundant arguments from
7362 translate_rule_action invocation.
7363 * src/reader.h (current_rule): Remove this unused extern.
7364 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
7365 * src/scan-code.l (translate_rule_action): Likewise.
7367 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
7369 Clean up yesterday's patch.
7370 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
7372 * src/reader.c (grammar_current_rule_action_append): ... here for
7373 consistency with grammar_current_rule_symbol_append.
7374 * tests/regression.at (Braced code in declaration in rules section):
7375 Make yyerror and yylex static as usual.
7377 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
7379 Fix bug that mistakes braced code in a declaration in the rules section
7380 to be a rule action. Mentioned at
7381 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
7382 * src/scan-gram.l: Move midrule action detection from the start of the
7383 scanning of any braced code to...
7384 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
7385 action. For readability, use $2 and @2 rather than the equivalent
7387 * tests/regression.at (Braced code in declaration in rules section):
7388 New test to catch the error fixed by the above patch.
7390 Work on code readability some.
7391 * src/scan-code.l (current_rule): Get rid of this misleading and
7392 redundant declaration: it's actually extern'ed in reader.h.
7393 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
7394 translate_action): Add a rule argument and use it instead of the global
7396 (translate_rule_action): This already receives current_rule through an
7397 argument, so pass it on to translate_action instead of assigning
7398 current_rule to current_rule.
7399 (translate_symbol_action, translate_code): Pass rule = NULL to
7402 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
7404 Rename %before-definitions to %start-header and %after-definitions to
7405 %end-header. Don't use these declarations to separate pre-prologue
7406 blocks from post-prologue blocks. Add new order-independent
7407 declarations %before-header and %after-header as alternatives to the
7408 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
7409 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
7410 * NEWS (2.3+): Update for these changes.
7411 * data/glr.c (b4_before_definitions): Update to...
7412 (b4_start_header): ... this.
7413 (b4_after_definitions): Update to...
7414 (b4_end_header): ... this.
7415 * data/glr.cc: Likewise.
7416 * data/lalr1.cc: Likewise.
7417 * data/yacc.c: Likewise.
7418 * doc/bison.texinfo (The prologue): Update names, and replace remaining
7419 prologue blocks with %*-header declarations.
7420 (Calc++ Parser): Likewise.
7421 (Decl Summary): Update names.
7422 (Table of Symbols): Update description.
7423 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
7424 (PERCENT_END_HEADER): ... this.
7425 (PERCENT_BEFORE_DEFINITIONS): Update to...
7426 (PERCENT_START_HEADER): ... this.
7427 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
7428 (declaration): Update token names and m4 macro names.
7429 When parsing %end-header and %start-header, invoke translate_code
7430 before muscle_code_grow, and no longer set global booleans to remember
7431 whether these declarations have been seen.
7432 Parse new %after-header and %before-header.
7433 * src/reader.c (before_definitions, after_definitions): Remove.
7434 (prologue_augment): Accept a new bool argument to specify whether to
7435 augment the pre-prologue or post-prologue.
7436 * src/reader.h (before_definitions, after_definitions): Remove these
7438 (prologue_augment): Add new bool argument.
7439 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
7440 (PERCENT_END_HEADER): ... this.
7441 (PERCENT_BEFORE_DEFINITIONS): Update to...
7442 (PERCENT_START_HEADER): ... this.
7443 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
7444 * tests/actions.at (Printers and Destructors): Update names.
7446 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
7448 Add comparison operators for C++ location classes. Discussed at
7449 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
7450 * data/c++.m4 (b4_define_location_comparison): New boolean %define
7451 declaration indicating whether filename_type has an operator==. If
7452 filename_type is `std::string', it defaults to `1', `0' otherwise.
7453 * data/location.cc: Iff b4_define_location_comparison is `1', add
7454 operator== and operator!= for class position and for class location.
7457 * src/scan-action.l: Remove unused file.
7458 * src/symtab.c (symbol_printer_set): Use printer_location not
7459 destructor_location.
7460 * src/symtab.h (struct symbol): Replace incorrect source comment for
7462 * tests/input.at (Incompatible Aliases): Update output with correct
7465 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
7467 Don't put the pre-prologue in the header file. For the yacc.c code
7468 file and the glr.c header and code files, move the pre-prologue before
7469 the token definitions. Add new %before-definitions and
7470 %after-definitions to declare code that will go in both the header file
7471 and code file. Discussed at
7472 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
7473 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
7475 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
7476 * NEWS (2.3+): Describe these changes.
7477 * data/glr.c (b4_pre_prologue): Move from within to before...
7478 (b4_shared_declarations): ... this.
7479 Add new b4_before_definitions before b4_token_enums.
7480 Add new b4_after_definitions at the end.
7481 * data/glr.cc (b4_pre_prologue): Replace with...
7482 (b4_before_definitions): ... this in the header file.
7483 (b4_after_definitions): New near the end of the header file.
7484 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
7485 code file right before including the header file.
7486 (b4_before_definitions): New in the previous position of
7487 b4_pre_prologue in the header file.
7488 (b4_after_definitions): New near the end of the header file.
7489 * data/yacc.c: Clean up some m4 quoting especially in the header file.
7490 (b4_token_enums_defines): In the code file, move to right before
7491 YYSTYPE for consistency with the header file.
7492 (b4_before_definitions): New right before b4_token_enums_defines in
7493 both the header and code file.
7494 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
7495 header and code file.
7496 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
7497 of prologues for %union dependencies.
7498 (Decl Summary): In %defines description, mention the effect of
7499 %before-definitions and %after-definitions on the header file.
7500 (Calc++ Parser): Forward declare driver in a %before-definitions rather
7501 than in the pre-prologue so that make check succeeds.
7502 (Table of Symbols): Add entries for %before-definitions and
7504 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
7505 %before-definitions.
7506 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
7507 (declaration): Parse those declarations and append to
7508 b4_before_definitions and b4_after_definitions, respectively.
7509 * src/reader.c (before_definitions, after_definitions): New bools to
7510 track whether those declarations have been seen.
7511 (prologue_augment): Add to the post-prologue if %union,
7512 %before-definitions, or %after-definitions has been seen.
7513 * src/reader.h (before_definitions, after_definitions): New extern's.
7514 * src/scan-gram.l: Scan the new declarations.
7515 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
7516 prologue block in a %before-definitions or a %after-definitions based
7517 on whether the %union is declared.
7518 * tests/regression.at (Early token definitions with --yacc, Early token
7519 definitions without --yacc): Move tests for token definitions into the
7520 post-prologue since token names are no longer defined in the
7523 2006-06-20 Akim Demaille <akim@epita.fr>
7525 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
7526 (symbol_get): Use it.
7527 * src/parse-gram.y: Use it.
7529 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
7531 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
7532 build succeeds when configured with --enable-gcc-warnings.
7534 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7536 * src/parse-gram.y (char_name): New function.
7537 (CHAR, STRING, string_content): For %printer, properly escape.
7538 (ID): Prefer fputs to fprintf.
7539 (id): Reindent to be consistent with other rules.
7540 Properly quote char.
7542 The Translation Project changed its way of publishing translations
7543 to maintainers. I haven't received any responses to my request
7544 for supporting the old way, or for documenting the new way. I
7545 have modified 'bootstrap' to use screen scraping
7546 (in this case, HTML scraping). This is unreliable and inelegant,
7547 but I don't see any better way. Yuck.
7548 * bootstrap (TP_URL, WGET_COMMAND): New vars.
7549 (get_translations): New function, which uses HTML scraping to
7550 deduce locations of latest translations.
7551 Use this function to grab both bison and bison-runtime .po files.
7552 Don't bother priming the pump for the runtime-po domain any more,
7553 as it's now translated better than bison is.
7555 2006-06-19 Akim Demaille <akim@epita.fr>
7557 * src/scan-gram.l: No longer "parse" things after `%union' until
7558 `{'. Rather, return a single "%union" token.
7559 No longer make symbols: return strings, and leave the conversion
7560 to symbols to the parser.
7561 (SC_PRE_CODE, token_type): Remove.
7562 * src/parse-gram.y (%union): New field `character'.
7565 (ID, ID_COLON): Now that the scanner no longer makes them
7566 identifiers, adjust all uses to invoke symbol_get.
7567 (id_colon): New, wraps the conversion from string to symbol.
7568 (%union): Accept a possible union_name.
7569 (symbol): Now can be a char.
7570 * data/c.m4 (b4_union_name): Leave a default value.
7571 * data/glr.c, data/yacc.c: Use it.
7573 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
7575 For associating token numbers with token names for "yacc.c", don't use
7576 #define statements unless `--yacc' is specified; always use enum
7577 yytokentype. Most important discussions start at:
7578 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
7579 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
7581 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
7582 * NEWS (2.3+): Mention.
7583 * data/c.m4 (b4_yacc_if): New.
7584 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
7586 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
7587 on token name definitions.
7588 * src/getargs.c (usage): Capitalize `Yacc' in English.
7589 * src/output.c (prepare): Define b4_yacc_flag.
7590 * tests/regression.at (Early token definitions): Test that tokens names
7591 are defined before the pre-prologue not just before the post-prologue.
7592 Remove this test case and copy to...
7593 (Early token definitions with --yacc): ... this to test #define's.
7594 (Early token definitions without --yacc): ... and this to test enums.
7596 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
7598 * NEWS: Reword the post-2.3 change to not be so optimistic about
7599 removing the old "look-ahead" spelling.
7600 Update previous look-ahead/lookahead change reports.
7601 * REFERENCES: look-ahead -> lookahead (since that's
7602 what he actually wrote).
7603 * doc/refcard.tex: look ahead -> lookahead,
7604 look-ahead -> lookahead
7606 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
7608 For consistency, use `lookahead' instead of `look-ahead' or
7609 `look_ahead'. Discussed starting at
7610 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
7612 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.
7613 * NEWS: For the next release, note the change to `--report'.
7614 * TODO, doc/bison.1: Update English.
7615 * doc/bison.texinfo: Update English.
7616 (Understanding Your Parser, Bison Options): Document as
7617 `--report=lookahead' rather than `--report=look-ahead'.
7618 * src/conflicts.c: Update English in comments.
7619 (lookahead_set): Rename from look_ahead_set.
7620 (flush_reduce): Rename argument look_ahead_tokens to lookahead_tokens.
7621 (resolve_sr_conflict): Rename local look_ahead_tokens to
7622 lookahead_tokens, and update other uses.
7623 (flush_shift, set_conflicts, conflicts_solve, count_sr_conflicts,
7624 count_rr_conflicts, conflicts_free): Update uses.
7625 * src/getargs.c (report_args): Move "lookahead" before alternate
7627 (report_types): Update uses.
7628 (usage): For `--report' usage description, state `lookahead' spelling
7629 rather than `look-ahead'.
7630 * src/getargs.h (report.report_lookahead_tokens): Rename from
7631 report_look_ahead_tokens.
7632 * src/lalr.c: Update English in comments.
7633 (compute_lookahead_tokens): Rename from compute_look_ahead_tokens.
7634 (state_lookahead_tokens_count): Rename from
7635 state_look_ahead_tokens_count.
7636 Rename local n_look_ahead_tokens to n_lookahead_tokens.
7637 (lookahead_tokens_print): Rename from look_ahead_tokens_print.

7683 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7685 * TODO: Add request from Nelson H. F. Beebe to be able to install
7686 Bison without installing the yacc script.
7688 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
7690 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
7691 and yytext if they're already #define'd.
7692 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
7693 * src/scan-code-c.c: ... here.

7700 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
7702 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
7703 loc argument as it shadows a global.
7704 * src/scan-gram.l: Remove stray comma that prevents boundary_set
7707 * src/.cvsignore: Add scan-code.c.
7709 2006-06-07 Akim Demaille <akim@epita.fr>
7711 * src/scan-gram.l: Move the "add a trailing ; to actions" code
7713 * src/scan-code.l: here.

7717 2006-06-07 Akim Demaille <akim@epita.fr>
7719 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
7721 2006-06-06 Akim Demaille <akim@epita.fr>
7723 Extract the parsing of user actions from the grammar scanner.
7724 As a consequence, the relation between the grammar scanner and
7725 parser is much simpler. We can also split "composite tokens" back
7727 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
7728 * src/scan-gram.l (add_column_width, adjust_location): Move to and
7730 * src/location.h, src/location.c (add_column_width)
7731 (location_compute): these.
7732 Fix the column count: the initial column is 0.
7733 (location_print): Be robust to ending column being 0.
7734 * src/location.h (boundary_set): New.
7735 * src/main.c: Adjust to scanner_free being renamed as
7737 * src/output.c: Include scan-code.h.
7738 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
7740 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
7741 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
7742 which is now, again, a separate token.
7743 Adjust all dependencies.
7744 Whereever actions with $ and @ are used, use translate_code.
7745 (action): Remove this nonterminal which is now useless.
7746 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
7747 (grammar_current_rule_action_append): Use translate_code.

7753 * src/scan-gram.h: this new file.
7754 (YY_DECL): Rename as...
7756 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
7757 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7758 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7759 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

7765 (increment_rule_length): Remove.
7766 (last_braced_code_loc): Rename as...
7767 (gram_last_braced_code_loc): this.
7768 Adjust to the changes of the parser.
7769 Move all the handling of $ and @ into...
7770 * src/scan-code.l: here.
7771 * src/scan-gram.l (handle_dollar, handle_at): Remove.

7784 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7786 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7787 Use Akim's wording from
7788 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
7790 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7792 Between Bison releases, manually append `+' to the previous Bison
7793 release number, and use that as a signal to automatically print the
7794 ChangeLog's CVS Id keyword from --version. Discussed starting at
7795 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
7796 * ChangeLog: Add Id header.
7797 * configure.ac (AC_INIT): Append `+' to `2.3'.
7798 * src/.cvsignore: Add revision.c.
7799 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
7800 (BUILT_SOURCES): Add revision.c.
7801 (revision.c): New target rule. This file defines a new global variable
7802 named revision. It initializes it with either the Id from ChangeLog
7803 or, if VERSION doesn't contain `+', with the empty string.
7804 * src/getargs.c (version): Print the value of revision.
7805 * src/revision.h: Extern revision.
7807 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7809 * NEWS: Version 2.3.
7810 * configure.ac (AC_INIT): Likewise.
7812 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7814 * data/glr.c (YYRECOVERING): Define to be a function-like macro
7815 with no arguments, not as an object-like macro. This is for
7816 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
7817 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
7818 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
7821 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
7823 * src/getargs.c (usage): Back out yesterday's modification of the
7824 --help output so that we don't have to wait for translation before
7827 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7829 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
7830 Problem reported by Akim Demaille.
7832 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
7834 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7836 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7838 * data/yacc.c (yy_reduce_print): Omit trailing white space in
7839 generated source code. Problem reported by Frans Englich in
7840 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7842 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7844 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7845 shell, not within 'make', so that 'make' by an ordinary builder
7846 (using GNU make) does not worry about configuring gzip. This also
7847 works around a bug reported independently by Keith Thompson and by
7848 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7849 stderr rather than stdout, messing up the build logs.
7851 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7853 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7854 to make sure that YYID will never be unused. This fixes a 'make
7855 maintainer-check' failure caused by the recent changes to the 'Trivial
7856 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7858 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7860 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7862 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7863 state before an empty RHS is always resolved here. Only the location
7864 of that state is guaranteed to be resolved, and that's enough. This
7865 fixes the remaining bug reported by Derek M. Jones in
7866 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7867 * tests/glr-regression.at (Uninitialized location when reporting
7868 ambiguity): Test the above case.
7869 Also, the embedded comments in this test case claim it checks the case
7870 of an empty RHS that has inherited the initial location. However, the
7871 corresponding LHS was already resolved, so yyresolveLocations didn't
7872 actually have reason to modify it. Fix this by forcing
7873 nondeterministic operation at the beginning of the parse.
7875 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7877 * data/c.m4 (b4_yy_symbol_print_generate):
7878 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7879 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7880 of the bugs reported today by Derek M Jones in
7881 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7882 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7883 defined to be a type name without parens or brackets.
7884 (Location Type): Similarly for YYLTYPE.
7885 * tests/regression.at (Trivial grammars): Put in a test for this
7886 bug that will be caught by 'make maintainer-check' (though not,
7887 alas, by 'make check' unless your compiler is picky).
7889 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
7891 * NEWS: Version 2.2.
7892 * configure.ac (AC_INIT): Likewise.
7894 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
7896 * data/glr.c (yyreportTree): Make room in yystates for the state
7897 preceding the RHS. This fixes the segmentation fault reported by Derek
7899 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7900 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7901 to the user. Reported for yyreportTree by Derek M. Jones later in the
7903 * THANKS: Add Derek M. Jones.
7904 Update my email address.
7905 Fix typo in Steve Murphy's name.
7907 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7909 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7910 checking against YYLAST that caused the parser to miss a potential
7911 alternative in its diagnostic.
7912 Problem reported by Maria Jose Moron Fernandez in
7913 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
7914 * data/lalr1.cc (yysyntax_error_): Likewise.
7915 * data/yacc.c (yysyntax_error): Likewise.
7916 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7917 tokens, in case we run into an older C compiler.
7918 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7919 Use them to check for the off-by-one error fixed above.
7921 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7922 YYSIZE_T, not size_t.
7923 * tests/regression.at (Trivial grammars): New test, to catch
7924 the error fixed by the above patch.
7926 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7928 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7930 Reported by Steve Murphy.
7932 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7934 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7935 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7937 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7939 Implement --trace=m4.
7940 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7941 * src/output.c (output_skeleton): When set, pass -dV to m4.
7943 Factor the handling of flags in m4.
7944 * src/output.c (prepare): Rename the muscle names debug, defines,
7945 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7946 * data/c.m4: Adjust.
7947 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7948 Use b4_define_flag_if to define other b4_FLAG_if macros.
7949 (b4_location_if): As a consequence, rename as...
7950 (b4_locations_if): this, for consistency.
7951 Adjust all the skeletons.
7953 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7955 * etc/bench.pm: Shorten bench names.
7957 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7959 * src/output.h, src/output.c (error_verbose): Move to...
7960 * src/getargs.h, src/getargs.c: here.
7962 Adjust dependencies.
7964 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7966 * data/c.m4 (b4_copyright): Put the special exception for Bison
7967 skeletons here, so we don't have to put it in each skeleton. All
7968 uses changed. Suggested by Akim Demaille. Also, wrap the
7969 copyright notice, in case it is longer than 80 columns. Replace
7970 comma by newline after title.
7972 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7974 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7975 incompatibility, not a bug. Mention that it wasn't fixed as of
7978 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7980 * examples/extexi: Enforce the precedence of concatenation over
7982 Reported by Tommy Nordgren.
7984 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7986 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7987 with the member "token".
7988 Reported by Martin Nylin.
7990 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
7992 * data/glr.c: Switch to Bison 2.2 special-exception language in
7993 the copyright notice. Use more-regular format for titles and
7995 * data/glr.cc: Likewise.
7996 * data/location.cc: Likewise.
7997 * data/yacc.cc: Likewise.
7998 * doc/bison.texinfo (Conditions): Document this.
7999 * NEWS: likewise. Upgrade version to 2.2.
8001 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
8003 * data/glr.cc: Remove dead code.
8005 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8007 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
8008 that variable and the line breaks the bootstrap. Problem reported
8009 by Juan M. Guerrero.
8011 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
8013 * doc/bison.texinfo (Multiple start-symbols): New.
8015 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
8017 * etc/README, etc/bench.pl: New.
8019 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
8021 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
8023 Reported by Mickael Labau.
8024 * tests/input.at (Torturing the Scanner): Test it.
8026 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
8028 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
8029 Problem reported by Bob Rossi.
8031 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
8033 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
8034 and didn't really work.
8035 For the index, use @ifnotinfo, not @iftex.
8036 Minor cleanups of spacing and terminology.
8038 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
8040 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
8041 of AT_NAME_PREFIX when %name-prefix is not used.
8043 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
8045 Apply --prefix to C++ skeletons too: they change the namespace.
8046 The test suite already exercize these cases.
8047 * data/c++.m4 (b4_namespace): New.
8048 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
8049 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
8050 * data/yacc.c, data/glr.c: Remove a useless `[]'.
8051 * doc/bison.texinfo: Document it.
8052 (Option Cross Key): Use @multitable in all formats. It looks
8053 nicer, even in TeX outputs.
8054 (Rules): Use the same code whatever the output type is.
8055 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
8056 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
8057 * tests/calc.at: Use it, instead of hard coding `yy'.

8061 * TODO: Remove dead items.
8063 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
8065 * doc/FAQ: Remove, merged into...
8066 * doc/bison.texinfo (FAQ): this.

8074 * doc/bison.texinfo (Calc++ Scanner): Use it.
8076 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
8078 Fix two nits reported by twlevo, plus one more that I discovered.
8080 * src/assoc.h (assoc_to_string): Give a name to the arg, as
8081 this is the usual Bison style.
8082 * src/location.h (location_print): Likewise.
8084 * src/reader.h (token_name): Likewise.
8086 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
8088 Fix some nits reported by twlevo.
8089 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
8090 and "POSIX". Use more-modern syntax for URLs. Mention C++
8091 and ask for Java. Don't hardwire OS version numbers. Add
8093 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
8094 * src/conflicts.c (solved_conflicts_obstack): Now static.
8096 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
8098 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
8099 page. Say "you can use it" not "you may use it" as on the web page;
8100 we're describing capabilities not granting permission.
8102 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
8104 * data/glr.c (yyresolveLocations): Rename local variables to avoid
8105 shadowing warnings. Use usual patter for iterating through RHS.
8106 * tests/glr-regression.at
8107 (Uninitialized location when reporting ambiguity):
8108 Modify yylex so that it uses its argument, rather than trying
8109 to rely on ARGSUSED (which doesn't work for gcc with warnings).
8110 const char -> char const.
8112 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):

8122 (yyresolveValue): Invoke yyresolveLocations before reporting an
8124 * doc/bison.texinfo (Default Action for Locations): Note
8125 YYLLOC_DEFAULT's usage for ambiguity locations.

8128 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
8130 * tests/glr-regression.at (Leaked semantic values when reporting
8131 ambiguity): Remove unnecessary union and type declarations.
8132 (Leaked lookahead after nondeterministic parse syntax error): New test
8134 * data/glr.c (yyparse): Check for zero stacks remaining before
8135 attempting to shift the lookahead so that you don't lose it.

8139 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
8140 * tests/glr-regression.at (Leaked semantic values when reporting
8141 ambiguity): New test case.
8142 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
8143 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
8144 now unnecessary yystackp parameter.
8145 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
8146 destructors can be called.

8153 Don't leak semantic values for parent RHS when a user action cuts the
8154 parser, and clean up related code a bit.
8155 * tests/glr-regression.at (Leaked merged semantic value if user action
8156 cuts parse): Rename to...
8157 (Leaked semantic values if user action cuts parse): ... this. Add check
8158 for leaked parent RHS values.
8159 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
8160 between an unresolved state (non-empty chain of semantic options) and
8161 an incomplete one (signaled by an empty chain).
8162 (yyresolveStates): Document the interface. Move all manipulation of a
8163 successfully or unsuccessfully resolved yyGLRState to...
8164 (yyresolveValue): ... here so that yyresolveValue always leaves a
8165 yyGLRState with consistent data and thus is easier to understand.
8166 Remove the yyvalp and yylocp parameters since they are always just
8167 taken from the yys parameter. When reporting a discarded merged value
8168 in debugging output, note that it is incompletely merged. Document the
8170 (yyresolveAction): If resolving any of the RHS states fails, destroy
8171 them all rather than leaking them. Thus, as long as user actions are
8172 written to clean up the RHS correctly, yyresolveAction always cleans up
8173 the RHS of a semantic option. Document the interface.

8292 During deterministic GLR operation, user actions should be able to
8293 influence the parse by changing yychar. To make this easier to fix and
8294 to make glr.c easier to evolve in general, don't maintain yytoken in

8322 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
8323 got from <http://bro-ids.org/download.html>. The bug is that
8324 when two actions appeared in succession, the second one was
8325 scanned before the first one was added to the grammar rule
8326 as a midrule action. Bison then output the incorrect warning
8327 "parse.y:905.17-906.36: warning: unused value: $3".

8575 * data/glr.c (yysplitStack): A little stylistic rewrite.
8577 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>

8581 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
8583 * doc/bison.texinfo: Fix some typos.
8584 (GLR Semantic Actions): New subsection discussing special
8585 considerations because GLR semantic actions might be deferred.
8586 (Actions): Mention look-ahead usage of yylval.
8587 (Actions and Locations): Mention look-ahead usage of yylloc.
8588 (Special Features for Use in Actions): Add YYEOF entry and mention it
8589 in the yychar entry.
8590 In the yychar entry, remove mention of the local yychar case (pure
8591 parser) since this is irrelevant information when writing semantic
8592 actions and since it's already discussed in `Table of Symbols' where
8593 yychar is otherwise described as an external variable.
8594 In the yychar entry, don't call it the `current' look-ahead since it
8595 isn't when semantic actions are deferred.
8596 In the yychar and yyclearin entries, add note about deferred semantic
8598 Add yylloc and yylval entries discussing look-ahead usage.
8599 (Look-Ahead Tokens): When discussing yychar, don't call it the
8600 `current' look-ahead, and do mention yylval and yylloc.
8601 (Error Recovery): Cross-reference `Action Features' when mentioning
8603 (Table of Symbols): In the yychar entry, don't call it the `current'
8605 In the yylloc and yylval entries, mention look-ahead usage.

8609 * tests/glr-regression.at: Update copyright year to 2006.
8611 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
8613 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
8614 use during nondeterministic operation to track which stacks have
8615 actually needed the current lookahead.
8616 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
8617 Allocate, deallocate, resize, and otherwise shuffle space for
8618 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
8619 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
8620 appropriately during nondeterministic operation.
8621 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
8622 members to store the current lookahead to be used by the deferred
8624 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
8625 from which the RHS is taken. Set the lookahead members of the new
8626 yySemanticOption according to the lookahead status for stack yyk.
8627 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
8628 yyaddDeferredAction.
8629 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
8630 members of yySemanticOption before invoking yyuserAction, and then set

8633 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
8634 * tests/glr-regression.at: Remove `.' from the ends of recent test case
8635 titles for consistency.
8636 (Leaked merged semantic value if user action cuts parse): In order to
8637 suppress lint warnings, use arguments in merge function, and assign
8638 char value < 128 in main.
8639 (Incorrect lookahead during deterministic GLR): New test case.
8640 (Incorrect lookahead during nondeterministic GLR): New test case.
8642 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

8651 * tests/glr-regression.at: For consistency with my newer test cases,
8654 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
8656 * data/glr.c (yyresolveValue): When merging semantic options, if at
8657 least one user action succeeds but a later one cuts the parse, then
8658 destroy the semantic value before returning rather than leaking it.
8659 (yyresolveStates): If a user action cuts the parse and thus
8660 yyresolveValue fails, ignore the (unset) semantic value rather than
8661 corrupting the yyGLRState, and empty the semantic options list since
8662 the user actions should have called all necessary destructors.
8663 Simplify code with YYCHK.
8664 * tests/glr-regression.at (Corrupted semantic options if user action
8665 cuts parse): New test case.
8666 (Undesirable destructors if user action cuts parse): New test case.
8667 Before applying any of this patch, this test case never actually failed
8668 for me... but only because the corrupted semantic options usually

8964 sed out the final state number.
8966 Work around portability problem on Solaris 10: flex-generated
8967 files include <stdio.h> before <config.h>, which messes up
8968 because the latter defines __EXTENSIONS__. Address the problem
8969 by creating two new little files that include <config.h> first,
8970 then include the flex-generated files. Rewrite everyone else
8971 to include <config.h> first, as well.
8972 * lib/timevar.c: Always include "config.h".

9067 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
9068 We can revert this once things settle down.

9311 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
9313 Undo the parts of the unlocked-I/O change that substituted
9314 putc or puts for printf. This might hurt performance a bit,
9315 but some people prefer the printf style.

9317 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

9346 Use unlocked I/O for a minor performance improvement on hosts like
9347 GNU/Linux and Solaris that support unlocked I/O. The basic idea
9348 is to use the gnlib unlocked-io module, and to prefer putc and

9531 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
9532 This works a bit better with glibc, if user code has already included
9534 * doc/bison.texinfo (Bison Parser): Document that users can't
9535 arbitrarily use malloc and free for other purposes. Document
9536 that <alloca.h> and <malloc.h> might be included.
9537 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
9538 user must declare alloca.
9540 * HACKING (release): Forwarn the Translation Project about
9543 2005-09-20 Akim Demaille <akim@epita.fr>
9545 * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
9547 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
9549 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
9550 (YYSTACK_ALLOC_MAXIMUM): Use it.
9551 (yysyntax_error): New function.
9552 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
9553 multiple syntax errors are reported, and alloca is being used.
9554 Instead, reallocate buffers twice as big each time, so that
9555 we waste at most half the allocated memory. Start with a small
9556 (128-byte) buffer that will suffice in most cases anyway.
9557 Use yysyntax_error to do most of the work.
9559 * doc/bison.texinfo (Error Reporting, Table of Symbols):
9560 yynerrs is the number of errors reported, not the number of
9563 * tests/glr-regression.at (Duplicated user destructor for lookahead):
9564 Mark it as expected to fail.
9565 Cast result of malloc; problem reported by twlevo@xs4all.nl.
9566 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
9567 Don't start user-code symbols with "yy", to avoid name space problems.
9569 2005-09-19 Akim Demaille <akim@epita.fr>
9571 Remove the traits, failed experiment.
9572 It never proved useful, and anyway because of the current
9573 definition, it was not possible to have several specialization of
9574 this traits, making it useless.
9575 * data/lalr1.cc (yy:traits): Remove.
9576 Inline its definitions in the parser class.
9578 2005-09-19 Akim Demaille <akim@epita.fr>

9585 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
9586 and yytoken for similarity with the other skeletons.

9600 * src/output.c (prepare): Likewise.
9601 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
9602 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
9603 is not defined. This is an awful hack, but it's enough for now.
9604 All callers changed.
9605 * tests/glr-regression-at (make_value): Args are const pointers now,
9606 to avoid GCC warning.
9607 (Duplicated user destructor for lookahead): New test. Currently
9608 skipped. It fails on my host but I'm not sure it'll always fail.
9610 2005-09-16 Akim Demaille <akim@epita.fr>
9612 * src/symtab.h (struct symbol): Declare the printer and destructor
9613 as const, to avoid accidental calls to free.
9614 (symbol_destructor_set, symbol_printer_set): Adjust.
9615 * src/symtab.c: Adjust.
9617 2005-09-16 Akim Demaille <akim@epita.fr>
9619 * data/c.m4 (b4_token_enums): New.
9620 (b4_token_defines): Rename as...
9621 (b4_token_enums_defines): this.
9622 (b4_token_defines): New, output only the #defines.
9623 * data/yacc.c, data/glr.c: Adjust.
9624 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
9625 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
9628 2005-09-16 Akim Demaille <akim@epita.fr>
9630 * data/lalr1.cc (yylex_): Remove, inline its code.
9631 (yyreport_syntax_error_): Remove, replaced by...
9632 (yysyntax_error_): this which returns a string and leaves to the
9633 caller the call to the users' error function.
9634 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
9635 Move from members of the parser object...
9636 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
9637 to local variables of the parse function.
9639 2005-09-16 Akim Demaille <akim@epita.fr>
9641 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
9642 since it's in Bison's name space.
9644 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
9646 * data/glr.c (yyresolveValue): Add default case to pacify
9647 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
9649 * NEWS: Document when yyparse started to return 2.
9650 * doc/bison.texinfo (Parser Function): Document when yyparse
9653 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
9654 (b4_filename_type): Renamed back from b4_file_name_type. All uses
9656 (class position): file_name -> filename (reverting). All uses changed.
9658 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
9660 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
9661 do anything if $@ exists. This reverts part of the 2005-07-07
9664 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
9666 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
9667 contains obsolete information and isn't worth distributing as a
9668 separate file anyway.
9669 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
9670 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
9671 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
9672 (yyparse): Abort if user code uses longjmp to throw an unexpected
9675 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
9677 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
9678 Suggested by twlevo@xs4all.nl.
9680 * data/glr.c (YYCHK1): Do not assume YYE is in range.
9681 This avoids a diagnostic from gcc -Wswitch-enum.
9682 Problem reported by twlevo@xs4all.nl.
9684 * doc/bison.texinfo: Don't use "filename", as per GNU coding
9685 standards. Use "file name" or "file" or "name", depending on
9687 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
9688 not to hack/foo.tab.c.
9689 (Calc++ Top Level): 2nd arg of main is not const.
9690 * data/glr.c: b4_filename -> b4_file_name.
9691 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
9693 (class position): filename -> file_name. All uses changed.

9708 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
9710 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
9713 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
9715 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
9716 All uses changed. Invoke user destructor after an error during a
9717 split parse (trivial change from Joel E. Denny).
9719 * tests/glr-regression.at
9720 (User destructor after an error during a split parse): New test case.
9721 Problem reported by Joel E. Denny in:
9722 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
9724 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9726 * README-cvs: Give URLs for recommended tools.
9727 Mention Gzip version problem, and bootstrapping issues.
9728 Remove troubleshooting section, as it's somewhat obsolete.
9730 * bootstrap (no_cache): New var, to accommodate different wget
9731 variants. Use it instead of '-C off'. Problem reported by
9734 * data/glr.c (yydestroyStackItem): New function.
9735 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
9736 debugging information. Problem reported by Joel E. Denny.

9746 * tests/glr-regression.at
9747 (User destructor for unresolved GLR semantic value): New test case.
9748 Problem reported by Joel E. Denny in:
9749 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
9751 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
9753 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
9755 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
9756 lib-prefix.m4, po.m4.
9758 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
9759 in yydestruct diagnostic, since it might not be an error.
9760 Problem reported by Joel Denny near end of
9761 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9762 * data/lalr1.cc (yyerturn): Likewise.
9763 * data/yacc.c (yyreturn): Likewise.
9764 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
9766 * src/files.c: Remove obsolete FIXME comment.
9768 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
9769 with the other templates, and to fix bogus run-on messages such
9770 as the one reported at the end of
9771 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9772 All callers changed to avoid the newline.
9773 (yyprocessOneStack): Output two lines rather than one, to accommodate
9774 the above change. This changes the debug output format slightly.
9776 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
9777 reported by Joel E. Denny in
9778 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
9780 * tests/glr-regression.at (Duplicate representation of merged trees):
9781 New test, from Joel E. Denny in:
9782 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
9783 * THANKS: Add Joel E. Denny.
9785 * configure.ac (AC_INIT): Bump to 2.0c.
9787 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
9789 * NEWS: Version 2.0b.
9791 * Makefile.am (SUBDIRS): Put examples before tests, so that
9792 "make check" doesn't finish with "All 1 tests passed".
9794 * tests/regression.at (Token definitions): Don't rely on
9795 AT_PARSER_CHECK for data that contains backslashes. It currently
9796 uses 'echo', and 'echo' isn't portable if its argument contains
9797 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9798 that the byte '\0xff' is not printable in the C locale; it is,
9799 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9800 not printable, so use '\0x81' to test.
9802 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
9803 version of GCC, since the macro is used with non-GCC compilers.
9805 Fix core dump reported by Pablo De Napoli in
9806 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
9807 * tests/regression.at (Invalid inputs with {}): New test.
9808 * src/parse-gram.y (token_name): Translate type before using
9811 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
9812 the user's name space. All uses changed to __attribute__
9814 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
9815 Add __attribute__ ((__noreturn__)).
9817 * etc/clcommit: Remove. We weren't using it, and it failed
9818 "make maintainer-distcheck".
9819 * Makefile.maint: Merge from coreutils.
9820 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
9821 (syntax-check-rules): Change list of rules as described below.
9822 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
9823 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
9824 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):

9828 (sc_space_tab, sc_error_exit_success, sc_changelog):
9829 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
9830 (makefile-check, po-check, author_mark_check):
9831 (makefile_path_separator_check, copyright-check):
9832 Use grep -n, to make it easier to find violations.
9833 Use CVS_LIST and CVS_LIST_EXCEPT.
9834 (header_regexp, h_re): Remove.
9836 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
9837 (my-distcheck): Use more-modern GCC flags.
9838 (signatures, %.asc): Remove.
9839 (rel-files, announcement): Remove signatures.
9840 Restore old updating code, even though we don't use it, so
9841 that we're the same as coreutils.
9842 (alpha, beta, major): Depend on news-date-check.
9843 Make the upload commands.
9845 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
9846 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
9847 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.

9852 * tests/sets.at: Likewise.
9854 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9855 we comment out the Autoconf version number.
9856 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9857 it's error-prone and "make maintainer-distcheck" rejects it.
9859 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9860 Indent calls to "error" to pacify "make maintainer-distcheck",
9861 when the calls are not intended to be translated.
9862 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9864 * src/Makefile.am (DEFS): Use +=, to pacify
9865 "make maintainer-distcheck".
9866 (bison_SOURCES): Add scan-skel.h.
9867 (sc_tight_scope): New rule, from coreutils.
9869 * src/files.c (src_extension, header_extension):
9870 Now static, not extern.
9871 * src/getargs.c (short_options): Likewise.
9872 * src/muscle_tab.c (muscle_table): Likewise.
9873 * src/parse-gram.y (current_class, current_type, current_prec):
9875 * src/reader.c (grammar_end, previous_rule_end): Likewise.
9876 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9877 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9878 void, to avoid warning when NLS is disabled.
9879 * src/output.c: Include scan-skel.h.
9880 (scan_skel): Remove decl, since scan-skel.h does this.
9882 Indent calls to "error" to pacify "make maintainer-distcheck".
9883 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9884 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9885 "make maintainer-distcheck".
9886 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
9887 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
9888 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
9889 (skel_lex_destroy, scan_skel): Move these decls to...
9890 * src/scan-skel.h: New file.
9891 * src/uniqstr.c (uniqstr_assert):
9892 Indent calls to "error" to pacify "make maintainer-distcheck".
9894 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9897 * tests/torture.at: Revamp to avoid misuse of atoi that
9898 "make maintainer-distcheck" complained about.
9900 * examples/extexi (message): Don't print a message more than once,
9901 and omit line-number decoration that makes Emacs compile think
9902 that informative messages are worth worrying about.
9904 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9906 * configure.ac: Update version number.
9908 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9910 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9911 autogenerated by the maintainer.
9912 * examples/calc++/.cvsignore: Add *.yy.
9914 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9915 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9916 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9918 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9920 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9921 from maintainer-distcheck about casting the argument of 'free'.
9923 * NEWS: Mention recent yytname changes.
9924 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9926 * bootstrap: For translations that have not yet been upgraded to
9927 the new runtime-po domain, prime the pump by extracting the
9928 relevant strings from the obsolete translations. This code can be
9929 removed once the bison-runtime domain has been translated by each
9932 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9933 now that token names are already quoted.
9935 Fix problem reported by Anthony Heading.
9936 * data/glr.c (YYTOKEN_TABLE): New macro.
9937 (yytname): Define if YYTOKEN_TABLE.
9938 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
9939 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
9940 (YYERROR_VERBOSE): Define the same way the other skeletons do.
9941 * src/output.c (prepare_symbols): Output token_table_flag.
9943 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9945 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9946 again if the first call fails.
9948 * data/glr.c (yytnamerr): New function.
9949 (yyreportSyntaxError): Use it to dequote most string literals.
9950 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9951 with other skeletons. All uses changed.
9952 (yytnameerr_): New function.
9953 (yyreport_syntax_error): Use it to dequote most string literals.
9954 * data/yacc.c (yytnamerr): New function.
9955 (yyerrlab): Use it to decode most string literals.
9956 * doc/bison.texinfo (Decl Summary, Calling Convention):
9957 Clarify quoting convention of yytname.
9958 * src/output.c (prepare_symbols): Quote all names. This undoes
9959 the 2005-04-17 change, which is now accomplished (mostly) via
9960 changes in the parsers as described above.
9961 * tests/regression.at (Token definitions, Web2c Actions):
9962 Undo most 2005-04-17 change here, too.
9964 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9966 Fix more problems reported by twlevo@xs4all.nl.
9967 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9968 remove trailing spaces. This loses the exit status of ./types,
9969 and isn't needed since ./types shouldn't be emitting trailing
9971 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9972 as the stack isn't valid in that case.
9974 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9975 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9976 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9977 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9979 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):

9981 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9984 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9985 overly-picky compilers that reject 'char *foo = "bar";'.
9987 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9988 to FILE * parameter, not to stderr. This fixes a typo introduced
9989 in the 2005-07-12 change.
9991 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
9992 warnings from GCC 4.
9994 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
9995 (yyglrShiftDefer, yysplitStack):
9996 Remove unused parameters b4_pure_formals. All uses changed.
9997 (yyglrShift): Remove unused parameters b4_user_formals.
9999 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
10001 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
10003 Destructor cleanups and regularization among the three skeletons.
10004 * NEWS: Document the behavior changes.
10005 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
10006 stack before failing, as the cleanup code will do it for us now.
10007 * data/lalr1.cc (yyerrlab): Likewise.
10008 * data/glr.c (yyparse): Pop everything off the stack before
10009 freeing it, so that destructors get called properly.
10010 * data/lalr1.cc (yyreturn): Likewise.
10011 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
10012 This is more consistent.
10013 * doc/bison.texinfo (Destructor Decl): Mention more reasons
10014 why destructors might be called. 1.875 -> 2.1.
10015 (Destructor Decl, Decl Summary, Table of Symbols):
10016 Some English-language cleanups for %destructor.
10017 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10018 Add output line for destructor of start symbol.
10019 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
10020 because of that same extra output line.
10022 * NEWS: Document minor wording changes in diagnostics of
10023 Bison-generated parsers.
10024 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
10025 Remove unused formals. All uses changed.
10026 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
10027 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
10028 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
10029 Rename yyoverflowab to yyexhaustedlab.
10030 When memory exhaustion occurs during syntax-error reporting,
10031 report it separately rather than in a single diagnostic; this
10033 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
10034 (Memory Exhausted): Renamed from Parser Stack Overflow.
10035 Revamp wording slightly to prefer "memory exhaustion".
10036 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
10038 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
10040 Add i18n support to the GLR skeleton. Partially fix the C++
10041 skeleton; a C++ expert needs to finish this. Remove debugging
10042 msgids; there's little point to having them translated, since they
10043 can be understood only by someone who can read the
10044 (English-language) source code.
10046 Generate runtime-po/bison-runtime.pot automatically, so that we
10047 don't have to worry about garbage getting in that file. We'll
10048 make sure after the next official release that old msgids don't
10050 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
10052 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10053 Now auto-generated.
10054 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10055 Fix typos in explanations of the runtime file.
10056 * bootstrap: Change gettext keyword from YYI18N to YY_.
10057 Use standard Makefile.in.in in runtime-po, since we'll arrange
10058 for backward-compatible bison-runtime.po files in a different way.
10059 * data/glr.c (YY_): New macro, from yacc.c.
10060 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10061 Translate messages intended for users.
10062 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10063 the wording in the other skeletons. We don't know that the memory
10065 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10066 Use same method that yacc.c uses.
10067 Don't translate debugging messages.
10068 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10069 it doesn't work (yet), and requires C++ expertise to fix.
10070 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10071 Move defn to a more logical place, to be consistent with other
10073 Don't translate debugging messages.
10074 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10075 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10076 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10077 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
10079 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
10080 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
10082 * tests/glr-regression.at (Badly Collapsed GLR States):
10084 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
10085 yylex should return 0 at EOF rather than aborting.
10087 Improve tests for stack overflow in GLR parser.
10088 Problem reported by twlevo@xs4all.nl.
10089 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
10091 (yyStackOverflow): Just longjmp, but with value 2 so that caller
10092 can handle the problem.
10093 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
10094 (yyparse): New local variable yyresult to record the result.
10095 Use result of setjmp to set it, rather than storing itinto
10097 (yyDone): Remove label.
10098 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
10099 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
10100 if YYABORT is used).
10101 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
10102 yyparse status; put status > 1 into diagnostic.
10103 Check that status==2 works.
10104 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
10105 Use exit status 3 for failure to open (which shouldn't happen).
10107 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
10109 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
10110 1 on syntax error; just let yyparse do its thing.
10111 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
10112 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
10113 (Exploding the Stack Size with Alloca):
10114 (Exploding the Stack Size with Malloc):
10115 Expect exit status 2, not 1, since the parser is supposed to blow
10116 its stack. Problem reported by twlevo@xs4all.nl.
10118 * data/glr.c (yyparse): Don't assume that the initial calls
10119 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
10120 Print a stack-overflow message and fail instead.
10121 Initialize the line-number information before creating the stack,
10122 so that the stack-overflow message can report line zero safely.
10124 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
10126 Fix problems reported by twlevo@xs4all.nl.
10127 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
10128 (yyuserMerge): Provide a default case if b4_mergers is empty.
10129 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
10130 * tests/glr-regression.at
10131 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
10132 Add casts to pacify C++ compilers.
10133 * tests/glr-regression.at (Improper merging of GLR delayed action
10134 sets): Declare yylex before using it.
10135 * tests/Makefile.am (maintainer-check-g++): Fix a stray
10136 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
10137 test for valgrind; valgrind is independent of g++.
10138 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
10139 for compatibility with POSIX 1003.1-2001 (if running coreutils).
10140 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
10141 Use a destructor, so that we can expand the stack. Change
10142 YYSTYPE to char * so that we can free it. Cast result of malloc.
10144 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10146 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
10147 a valgrind failure. Problem reported by twlevo@xs4all.nl.
10149 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
10151 * PACKAGING: New file, suggested by Bruno Haible and taken from
10152 similar wording in gettext's PACKAGING file.
10153 * NEWS: Mention PACKAGING.
10154 * Makefile.am (EXTRA_DIST): Add PACKAGING.
10156 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
10158 * NEWS: Document recent i18n improvements.
10159 * bootstrap: Get runtime translations into runtime-po.
10160 Create runtime-po files automatically, if possible.
10161 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
10162 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
10163 does not infringe on the user's name space.
10164 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
10165 * doc/bison.texinfo (Internationalization): Revamp the English
10166 and Texinfo syntax a bit, to try to make it clearer.
10167 (Bison Options, Option Cross Key): Mention --print-localedir.
10168 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
10169 YYENABLE_NLS. Quote a bit more.
10170 * runtime-po/.cvsignore: New file.
10171 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
10172 * runtime-po/Rules-quot: Remove; now created by bootstrap.
10173 * runtime-po/quot.sed: Likewise.
10174 * runtime-po/boldquot.sed: Likewise.
10175 * runtime-po/en@quot.header: Likewise.
10176 * runtime-po/en@boldquot.header: Likewise.
10177 * runtime-po/insert-header.sin: Likewise.
10178 * runtime-po/remove-potcdate.sin: Likewise.
10179 * runtime-po/Makevars: Likewise.
10180 * runtime-po/LINGUAS: Likewise.
10181 * runtime-po/de.po: Likewise; we will rely on the translation project
10182 to maintain this, so "bootstrap" should get it.
10183 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
10185 * src/main.c (main): Bind the bison-runtime domain, too.
10187 2005-07-12 Bruno Haible <bruno@clisp.org>
10189 * data/yacc.c: Include <libintl.h> when NLS is enabled.
10190 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
10191 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
10192 * runtime-po: New directory.
10193 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
10194 $(DOMAIN).pot-update rule, so that old messages are never dropped.
10195 * runtime-po/Rules-quot: New file, copied from po/.
10196 * runtime-po/quot.sed: Likewise.
10197 * runtime-po/boldquot.sed: Likewise.
10198 * runtime-po/en@quot.header: Likewise.
10199 * runtime-po/en@boldquot.header: Likewise.
10200 * runtime-po/insert-header.sin: Likewise.
10201 * runtime-po/remove-potcdate.sin: Likewise.
10202 * runtime-po/Makevars: New file.
10203 * runtime-po/POTFILES.in: New file.
10204 * runtime-po/LINGUAS: New file.
10205 * runtime-po/bison-runtime.pot: New file.
10206 * runtime-po/de.po: New file.
10207 * m4/bison.m4: New file.
10208 * Makefile.am (SUBDIRS): Add runtime-po.
10209 (aclocaldir, aclocal_DATA): New variables.
10210 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
10212 * src/getargs.c (usage): Document --print-localedir option.
10213 (PRINT_LOCALEDIR_OPTION): New enum item.
10214 (long_options): Add --print-localedir option.
10215 (getargs): Handle --print-localedir option.
10216 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
10217 (Internationalization): New section.
10219 2005-07-12 Akim Demaille <akim@epita.fr>
10221 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
10222 for consistency with the rest of the code.
10223 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
10226 2005-07-12 Akim Demaille <akim@epita.fr>
10228 * src/parse-gram.y: Use %printer instead of YYPRINT.
10230 2005-07-12 Akim Demaille <akim@epita.fr>
10232 * src/symtab.h, src/symtab.c (symbol_print): New.
10233 * src/symlist.h, src/symlist.c (symbol_list_print): New.
10234 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
10236 2005-07-12 Akim Demaille <akim@epita.fr>
10238 * data/glr.c (b4_syncline): Fix (swap) the definitions of
10239 b4_at_dollar and b4_dollar_dollar.
10241 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
10243 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
10244 and Pennello's paper.
10246 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
10248 * data/yacc.c (yyparse): Undo previous patch. Instead,
10249 set yylsp[0] and yyvsp[0] only if the initial action
10250 sets yylloc and yylval, respectively.
10252 * data/yacc.c (yyparse): In the initial action, set
10253 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
10254 This avoids the use of undefined variables if the initial
10255 action does not set yylloc and/or yylval.
10257 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10259 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
10260 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
10261 Remove from CVS. These files are automatically generated.
10262 * examples/extexi: Clarify that this file is now part of Bison,
10263 not GNU M4, and that it works with any POSIX-compatible Awk.
10264 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
10265 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
10266 so that we also get calc++-parser.yy. Geneate it.
10267 Use $(AWK), not gawk, since any conforming Awk will do.
10268 Put comment before action, since older 'make' can't handle comment
10270 $(BUILT_SOURCES): List all built sources, not just some of them.
10271 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
10272 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
10273 $($(calc_sources_generated)): Remove unnecessary test for existence
10274 of target. (This had a shell syntax error anyway; a stray "x".)
10275 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
10277 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
10279 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
10280 implied by the other modules.
10282 2005-07-06 Akim Demaille <akim@epita.fr>
10284 Bind examples/calc++ to the package.
10285 * examples/calc++/Makefile: Remove, replaced by...

10287 * examples/calc++/test: Remove input.
10288 * examples/calc++/compile: Remove.
10289 * examples/Makefile.am: New.
10290 * configure.ac, Makefile.am: Adjust.

10293 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
10295 * data/glr.c (yyFail): Drastically simplify; since the format argument
10296 never had any % directives, we can simply pass it to yyerror.
10297 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
10298 be modified later, as that is the usual style in glr.c.
10299 Problems reported by Paul Hilfinger.
10301 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
10302 and size overflow errors.
10303 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
10304 in case the user prolog sets feature-test macros like _GNU_SOURCE.
10305 (YYSIZEMAX): New macro.
10306 (yystpcpy): New function, taken from yacc.c.
10307 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
10308 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
10309 so that we don't have to maintain their signatures.
10310 (yyFail): Check for buffer overflow, by using vsnprintf rather
10311 than vsprintf. Allocate a bigger buffer if possible.
10312 Report an error if buffer allocation fails.
10313 (yyStackOverflow): New function.
10314 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
10315 the initialization was successful. It might fail if storage was
10317 (yyexpandGLRStack): Add more checks for storage allocation failure.
10318 Use yyStackOverflow to report failures.
10319 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
10320 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
10321 Don't assume stack number fits in int.
10322 (yysplitStack): Check for storage allocation failure.
10323 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
10324 can print diagnostics on storage allocation failure. All callers
10326 (yyresolveValue): Use yybool for boolean.
10327 (yyreportSyntaxError): Check for size-calculation overflow.
10328 This code is taken from yacc.c.
10329 (yyparse): Check for storage allocation errors when allocating
10332 2005-07-05 Akim Demaille <akim@epita.fr>
10334 Extract calc++ from the documentation.
10335 * doc/bison.texinfo (Calc++): Add the extraction marks.
10336 * examples/extexi: New, from the aborted GNU Programming 2E.
10337 Separate the different paragraph of a file with empty lines.
10338 * examples/Makefile: Use it to extract the whole calc++ example.
10340 2005-06-24 Akim Demaille <akim@epita.fr>
10342 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
10345 2005-06-22 Akim Demaille <akim@epita.fr>
10347 * doc/bison.texinfo (C++ Language Interface): First stab.
10348 (C++ Parsers): Remove.
10350 2005-06-22 Akim Demaille <akim@epita.fr>
10352 * data/lalr1.cc (yylex_): Honor %lex-param.
10354 2005-06-22 Akim Demaille <akim@epita.fr>
10356 Start a set of simple examples.
10357 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
10358 * examples/calc++/calc++-driver.hh,
10359 * examples/calc++/calc++-parser.yy,
10360 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
10361 * examples/calc++/compile, examples/calc++/test: New.
10363 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
10365 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
10366 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
10367 which stems from the 2005-05-27 patch.
10369 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
10371 * data/glr.c: Modify treatment of unused parameters to permit use
10372 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
10374 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
10376 Fix infringement on user name space reported by Janos Zoltan Szabo.
10377 * data/yacc.c (yyparse): strlen -> yystrlen.
10379 2005-05-30 Akim Demaille <akim@epita.fr>
10381 * data/lalr1.cc (_): New.
10382 Translate the various messages.
10384 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
10386 Fix infringement on user name space reported by Bruno Haible.
10387 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
10388 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
10389 the user's name space.
10390 (alloca): Include <stdlib.h> to get it, if it's not built in.
10391 (YYMALLOC, YYFREE): Define only if needed.
10392 (malloc, free): Declare, but only if needed, as this infringes on
10393 the user name space.
10395 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10397 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
10398 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
10400 * lib/ebitset.c (min, max): Undef before defining.
10401 * lib/vbitset.c (min, max): Likewise.
10402 * lib/subpipe.c (create_subpipe): Save local variables in case
10403 vfork clobbers them.
10405 2005-05-24 Bruno Haible <bruno@clisp.org>
10407 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
10408 error message syntax used by gcc-4.0.
10410 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
10412 * README: Mention m4 1.4.3. Remove obsolete advice about
10413 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
10415 * bootstrap: Remove workaround for problem I encountered with
10416 gettext 0.14.1; it seems to be fixed now.
10418 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
10420 * NEWS: Version 2.0a.
10422 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
10423 the previous change.
10425 Various maintainer cleanups.
10426 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
10427 conftest*, for benefit of CVS commands run at the same time as
10428 "configure". Add build-aux, since "bootstrap" now creates it and
10430 * Makefile.cfg (move_if_change): Remove.
10431 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
10432 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
10433 (po_repo, do-po-update, po-update, wget_files, get-targets):
10434 (config.guess-url_prefix, config.sub-url_prefix):
10435 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
10436 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
10437 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
10439 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
10440 this is now the recommended name.
10441 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
10442 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
10443 ylwrap. These files now go into build-aux.
10444 * config/move-if-change: Remove.
10445 * config/prev-version.txt: Bump from 1.75 to 2.0.
10447 * bootstrap: Add stdio-safer, unistd-safer modules.
10448 Remove m4/glibc2.m4 (introduced by latest gnulib, but
10450 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
10451 fopen-safer.c, stdio-safer.h, unistd-safer.h.
10452 * lib/subpipe.c: Include "unistd-safer.h".
10453 (create_subpipe): Make sure all the newly-created
10454 file descriptors are > 2, so that diagnostics don't
10455 get sent down them (which might cause Bison to hang, in theory).
10456 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
10457 * src/files.c (xfopen): Use fopen_safer, not fopen.
10459 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
10460 yesterday's yacc.c fix.
10462 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
10464 * data/glr.c, data/lalr1.cc: Update copyright date.
10466 Fix a destructor bug reported by Wolfgang Spraul in
10467 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
10468 * data/yacc.c (yyabortlab): Don't call destructor, and
10469 don't set yychar to EMPTY.
10470 (yyoverflowlab): Don't call destructor.
10471 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
10472 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
10473 since we no longer output the message "discarding lookahead token
10476 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10478 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
10479 fix a small glitch in debugging output.
10480 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
10481 after YY_SYMBOL_PRINT where needed.
10483 (struct yyGLRState): Add some comments.
10484 (struct yySemanticOption): Add some comments.
10485 (union yyGLRStackItem): Add comment.
10487 (yymergeOptionSets): Correct this to properly perform the union,
10488 avoiding infinite reported by Michael Rosien.
10491 * tests/glr-regression.at: Add test for GLR merging error reported

10532 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
10534 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
10535 Problem reported by Ralf Menzel.
10537 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10539 * tests/actions.at: Test that stack overflow invokes destructors.
10540 From Marcus Holland-Moritz.
10541 * data/yacc.c (yyerrlab): Move the code that destroys the stack
10543 (yyreturn): to here. That way, destructors are called properly
10544 even if the stack overflows, or the user calls YYACCEPT or
10545 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
10546 (yyoverflowlab): Destroy the lookahead.
10548 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
10550 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
10552 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
10554 * NEWS: Bison-generated C parsers no longer quote literal strings
10555 associated with tokens.
10556 * src/output.c (prepare_symbols): Don't escape strings,
10557 since users don't want to see C escapes.
10558 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
10560 * tests/input.at (Torturing the Scanner): Likewise.
10561 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
10563 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
10565 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
10566 the data size is known to be too small and we can't increase it.
10567 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
10569 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
10571 * src/parse-gram.y: Include quotearg.h.
10572 (string_as_id): Quote $1 before using it as a key, since the
10573 lexer no longer quotes it for us.
10574 (string_content): Don't strip quotes, since lexer no longer
10576 * src/scan-gram.l: Include quotearg.h.
10577 ("\""): Omit quote.
10578 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
10579 a key, since the rest of the lexer doesn't quote it.
10580 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
10581 * tests/regression.at (Token definitions): Check for backslashes
10584 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
10585 (YYSIZE_T): Define to unsigned long int when using an older compiler.
10586 (yyparse): Revamp code to generate long syntax error message, to
10587 make it easier to translate, and to avoid problems with arithmetic
10588 overflow. Change "virtual memory" to "memory" in diagnostic, since
10589 we don't know whether the memory is virtual.
10591 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10593 * NEWS: Bison-generated C parsers now use the _ macro to
10595 * data/yacc.c (_) [!defined _]: New macro.
10596 All English strings wrapped inside this macro.
10597 * doc/bison.texinfo (Bison Parser): Document _.
10598 * po/POTFILES.in: Include src/parse-gram.c, since it now
10599 includes translateable strings that parse-gram.y doesn't.
10601 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
10603 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
10604 reverting the 2004-10-11 change to this function.
10605 (symbol_check_alias_consistency): Don't call symbol_type_set
10606 if the type name is already correct.
10607 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
10609 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
10611 * tests/regression.at (Token definitions): Don't use a token named
10612 c, as that generates a "#define c ..." that runs afoul of buggy
10613 stdlib.h that uses the identifier c as a member of struct
10614 drand48_data. Problem reported by Horst Wente.
10616 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
10618 * bootstrap: Change translation URL from
10619 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
10620 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
10621 redirection glitches. Problem reported by twlevo@xs4all.nl.
10623 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
10625 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
10626 after operands; POSIX says this isn't portable for the c99 command.
10628 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
10630 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
10631 immediately if a data overrun has occurred; this may help us track
10632 down what may be a spurious failure on MacOS.
10634 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
10636 Respond to problems reported by twlevo@xs4all.nl.
10638 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
10640 * src/vcg.h: Comment fix.
10641 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
10642 (G_CMAX): Change to -1 instead of INT_MAX.
10644 * data/yacc.c (yyparse): Omit spaces before #line.
10646 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
10648 * src/tables.c (state_number_to_vector_number): Put it inside an
10649 "#if 0", since it's not currently used. Problem reported by
10652 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
10654 * src/output.c (escaped_output): Renamed from
10655 escaped_file_name_output, since we now use it for symbol tags as
10656 well. All uses changed.
10657 (symbol_destructors_output, symbol_printers_output):
10658 Escape symbol tags too.
10659 Problem reported by Matyas Forstner in
10660 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
10662 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
10664 * src/output.c (user_actions_output, token_definitions_output,
10665 symbol_destructors_output, symbol_printers_output): Likewise.
10666 * src/reader.c (prologue_augment): Likewise.
10667 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
10669 * src/vcg.c (output_edge): Don't quote linestyle arg.
10670 Problem reported by twlevo@xs4all.nl.
10672 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
10674 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
10675 example, reported by Derek M Jones. Also, make the example even
10676 more outrageous, to better illustrate how bad the problem is.
10678 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
10680 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
10681 putsym. Typo reported by Sebastian Piping.
10683 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10685 * doc/bison.texinfo (Language and Grammar): some -> same
10686 (Epilogue): int he -> in the
10687 Typos reported by Sebastian Piping via Justin Pence.
10689 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10691 * tests/glr-regression.at (Improper handling of embedded actions
10692 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
10693 embedded actions and $-N in GLR parsers", work around an Autoconf bug
10694 with dollar signs in test names.
10695 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
10696 for a similar reason.
10698 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
10700 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
10701 wants to redefine G_VIEW.
10703 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
10705 * src/vcg.c (get_view_str): Remove case for normal_view.
10706 Problem reported by twlevo@xs4all.nl.
10708 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
10710 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
10711 Problem reported by twlevo@xs4all.nl.
10713 * doc/bison.texinfo: Change @dircategory from "GNU programming
10714 tools" to "Software development". Requested by Richard Stallman
10717 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
10719 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
10720 Problem reported by twlevo@xs4all.nl.
10722 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
10724 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
10725 keyword; it's not needed with modern compilers, and it doesn't
10726 affect correctness with older compilers. Suggested by
10729 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
10731 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
10732 gcc -Wswitch-default.
10733 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10734 * data/yacc.c (yyparse): Likewise.
10736 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
10738 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
10739 already. Let config.h define any nonstandard values.
10741 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
10743 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
10744 for the benefit of slower hosts. Problem reported by
10745 Nelson H. F. Beebe.
10747 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
10749 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
10750 being defined and not used.
10751 * data/lalr1.cc (yyparse): Likewise.
10752 Use "if (false)" rather than "if (0)".
10754 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
10756 * TODO: Mention that we should allow NUL bytes in tokens.
10758 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
10760 * src/scan-skel.l (<<EOF>>): Don't close standard output.
10761 Problem reported by Hans Aberg.
10763 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
10765 * src/getargs.c (version): Happy new year; update overall
10766 program copyright date from 2004 to 2005.
10768 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
10769 Problem reported by Hans Aberg.
10770 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
10771 (Output file names.): Add a test for the case when standard output
10774 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
10776 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
10777 to fix an oversight in the Bison 2.0 manual.
10779 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
10781 * NEWS: Version 2.0. Reformat the existing news items since
10782 1.875, so that related items are grouped together.
10783 * configure.ac (AC_INIT): Bump version to 2.0.
10784 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
10786 * tests/torture.at (Exploding the Stack Size with Alloca): Set
10787 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
10788 otherwise, we're not testing alloca. Unfortunately there's no
10789 simple way to consult HAVE_ALLOCA here.
10791 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
10794 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
10795 hand. This avoids a warning about comparing int to size_t when
10796 GCC warnings are enabled.
10798 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
10800 * NEWS: Bison-generated parsers no longer default to using the
10801 alloca function (when available) to extend the parser stack, due
10802 to widespread problems in unchecked stack-overflow detection.
10803 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
10804 responsibility to set it to a positive value. This lets the user
10805 specify a value that is not a preprocessor constant.
10806 * data/yacc.c (YYMAXDEPTH): Likewise.
10807 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
10808 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
10809 to be a compile-time constant. However, explain the constraints on it.
10810 Also, explain the constraints on YYINITDEPTH.
10811 (Table of Symbols): Explain that alloca is no longer the default.
10812 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
10815 * doc/bison.texinfo (Location Default Action): Mention that n must
10816 be zero when k is zero. Suggested by Frank Heckenbach.
10818 2004-12-22 Akim Demaille <akim@epita.fr>
10820 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
10821 (parser::state_type, parser::semantic_type, parser::location_type):
10822 Private, not public.
10823 (parser::parse): Return ints, not bool.
10824 Returning a bool introduces a problem: 0 corresponds to false, and
10825 it seems weird to return false on success. Returning true changes
10826 the conventions for yyparse.
10827 Alternatively we could return void and send an exception.
10828 There is no clear consensus (yet?).
10829 (state_stack, semantic_stack, location_stack): Rename as...
10830 (state_stack_type, semantic_stack_type, location_stack_type): these.
10831 Private, not public.
10832 * tests/c++.at: New.
10833 * tests/testsuite.at, tests/Makefile.am: Adjust.
10835 2004-12-21 Akim Demaille <akim@epita.fr>
10837 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
10839 2004-12-21 Akim Demaille <akim@epita.fr>
10841 Don't impose std::string for filenames.
10843 * data/lalr1.cc (b4_filename_type): New.
10844 (position::filename): Use it.
10845 (parser.hh): Move the inclusion of stack.hh and location.hh below
10846 the user code, so that needed headers for the filename type can be
10848 Forward declare them before the user code.
10849 * tests/Makefile.am (check-local, installcheck-local): Pass
10850 TESTSUITEFLAGS to the TESTSUITE.
10852 2004-12-20 Akim Demaille <akim@epita.fr>
10854 Use more STL like names: my_class instead of MyClass.
10856 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
10857 (SemanticStack, SemanticType, StateStack, StateType)
10858 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10859 (Parser::value): Rename as...

10861 (semantic_type, state_stack, state_type, token_number_type, stack)
10862 (slice, traits, parser::yylloc, parser::yylval): these.
10864 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10866 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10868 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10869 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10871 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10873 Remove uses of 'short int' and 'unsigned short int'. This raises
10874 some arbitrary limits. It uses more memory but nowadays that's
10875 not much of an issue.
10877 This change does not affect the generated parsers; that's a different
10878 task, as some users will want to conserve memory there.
10880 Ideally we should use size_t to represent all object counts, and
10881 something like ptrdiff_t to represent signed differences of object
10882 counts; but that will require more code-cleanup than I have the
10883 time to do right now.
10885 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10886 Use size_t, not int or short int, to count objects.

10906 2004-12-17 Akim Demaille <akim@epita.fr>
10908 * data/lalr1.cc: Extensive Doxygenation.
10909 (error_): Rename as...
10910 (error): this, since it is visible to the user.
10912 (Parser::message): Now an automatic variable from...
10913 (Parser::yyreport_syntax_error_): here.
10914 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10916 * tests/input.at: Escape $.

10920 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10921 Parenthesize rhs to avoid obscure problems with mistakes like
10922 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10923 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10924 b4_rhs_location): Likewise.

10928 2004-12-16 Akim Demaille <akim@epita.fr>
10930 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10931 yacc.c: be sure to stay within yycheck_.
10932 * tests/actions.at: Re-enable C++ tests.
10934 2004-12-16 Akim Demaille <akim@epita.fr>
10936 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for

10941 Use #define to handle the %name-prefix.
10943 * data/glr.c, data/yacc.c: Comment changes.
10944 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10945 so that one can refer to yylex in the parser file, and have it
10946 renamed, as is the case with other skeletons.
10948 2004-12-16 Akim Demaille <akim@epita.fr>

10970 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10972 Fix some problems reported by twlevo at xs4all.
10973 * src/symtab.c (symbol_new): Report an error if the input grammar
10974 contains too many symbols. This is better than calling abort() later.
10975 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10976 (struct node, struct graph):
10977 Rename member expand to stretch. All uses changed.

10989 (report_syntax_error_, translate_): Rename as...
10990 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)

10997 Move the trace here.
10998 Take the %name-prefix into account.
10999 Reported by Alexandre Duret-Lutz.
11001 2004-12-15 Akim Demaille <akim@epita.fr>
11003 Simplify the C++ parser constructor.
11005 * data/lalr1.cc (debug_): Rename as...
11006 (yydebug_): so that the parser's internals are always in the yy*
11009 (b4_parse_param_decl): Remove the leading comma as it is now only
11010 called as unique argument list.
11011 (Parser::Parser): Remove the constructor accepting a location and
11012 an initial debugging level.
11013 Remove from the other ctor the argument for the debugging level.
11014 (debug_level_type, debug_level, set_debug_level): New.
11016 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
11019 2004-12-15 Akim Demaille <akim@epita.fr>
11021 Remove b4_root related material: failure experiment
11022 (which goal was to allow to derive from a class).
11024 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
11025 definitions and uses.
11027 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
11029 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
11030 not 2, since it's not portable to subtract 1 from the start of an
11031 array. The new item 0 is never set or used. All uses changed.
11033 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
11034 the default definition of YYLLOC_DEFAULT. Problem reported
11035 by Frank Heckenbach.
11037 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
11039 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
11040 the normal case and one for the error case. Just use the
11041 first one uniformly. Problem reported by Frank Heckenbach.
11042 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
11043 use exactly the same macro in both places.
11044 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
11045 so that the normal-case YYRHSLOC works for the error case too.
11047 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
11048 (YYLLOC_DEFAULT): Use the same macro as glr.c.
11049 * doc/bison.texinfo (Location Default Action): Don't claim that
11050 we have an array of locations. Use the same macro for both glr
11051 and lalr parsers. Mention YYRHSLOC. Mention what happens when
11054 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11056 * HACKING: Update email addresses to send announcements to.
11058 * configure.ac (AC_INIT): Bump version to 1.875f.
11060 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11062 * NEWS: Version 1.875e.
11063 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
11065 * src/scan-skel.l: Include "complain.h", for "fatal".
11067 * src/relation.h (relation_print, relation_digraph):
11068 Relation sizes are of type relation_node, not size_t (this is
11069 merely a doc fix, since the two types are equivalent).
11070 (relation_transpose): Relation sizes are of type relation_node,
11072 * src/relation.c: Likewise.
11073 (top, infinity): Now of type relation_node, not int.
11074 (traverse, relation_transpose): Use relation_node, not int.
11076 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
11077 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
11078 (yyparse): Remove unused local introduced in 2004-10-25 patch.
11080 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
11081 specifying whether the test should be skipped. Use it tp
11082 specify that the [%defines %skeleton "lalr1.cc"] tests currently
11083 fail on some hosts, and should be skipped.
11085 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
11087 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
11088 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
11089 unless otherwise specified below.
11091 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
11092 to allocate kernel_base, kernel_items, kernel_size, since
11093 they needn't be initialized to 0.
11094 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
11095 * src/closure.c (new_closure): Likewise, for itemset.
11096 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

11104 (relation_transpose): Likewise for new_R, end_R.
11105 * src/symtab.c (symbols_token_translations_init): Likewise for
11106 token_translations.
11107 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
11108 (token_actions): Likewise for yydefact, actrow, conflrow,
11110 (save_column): Likewise for froms[symno], tos[symno].
11111 (goto_actions): Likewise for state_count.
11112 (pack_table): Likewise for base, pos, check.
11113 (tables_generate): Likewise for width.
11115 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
11116 for initial core. Just have a separate core, so we needn't worry
11117 about whether kernel_size and kernel_base are initialized.
11119 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
11120 kernel_size, kernel_items): Remove unnecessary initialization.
11121 * src/conflicts.c (conflicts): Likewise.
11122 * src/derives.c (derives): Likewise.

11125 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
11126 conflrow, conflict_table, conflict_list, table, check):
11129 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
11130 This is because all callers pass unsigned int.
11131 * src/closure.h (new_closure): Likewise.
11133 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
11134 (build_relations): Initialize includes[i] in all cases.
11135 * src/reader.c (packgram): Always initialize rules[ruleno].prec
11136 and rules[ruleno].precsym. Initialize members in order.
11137 * src/relation.c (relation_transpose): Always initialize new_R[i]
11139 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
11141 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
11142 conflict_list[0] was always 0, but now it isn't initialized.
11144 * src/table.c (table_grow): When conflict_table grew, the grown
11145 area wasn't cleared. Fix this.
11147 * lib/.cvsignore: Add strdup.c, strdup.h.
11148 * m4/.cvsignore: Add strdup.m4.
11150 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
11152 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
11153 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
11154 GOTO_NUMBER_MAXIMUM, since we occasionally compute
11155 ngotos + 1 without checking for overflow.
11156 (build_relations): Use END_NODE, not -1, to denote end of edges.
11157 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
11158 build_relations): Use goto_number, not int, for goto numbers.
11159 * src/tables.c (save_column, default_goto): Likewise.
11161 2004-11-23 Akim Demaille <akim@epita.fr>
11163 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
11164 of #defining from yystype.
11165 Don't typedef yystype, C++ does not need it.
11166 This lets it possible to forward declare it as union.
11168 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
11170 * bootstrap (gnulib_modules): Add extensions.
11171 Problem reported by Jim Meyering.
11173 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
11175 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
11176 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
11177 src/system.h, src/tables.c: XFREE -> free, to accommodate
11178 recent change to gnulib xalloc.h.
11179 Problem reported by Jim Meyering.
11181 2004-11-17 Akim Demaille <akim@epita.fr>
11183 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
11185 2004-11-17 Akim Demaille <akim@epita.fr>,
11186 Alexandre Duret-Lutz <adl@gnu.org>
11188 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
11190 (YYCDEBUG): Adjust.
11191 Use it instead of cdebug_.
11192 (Parser::debug_stream, Parser::set_debug_stream): New.
11193 (Parser::symprint_): Define cdebug_ for temporary backward
11195 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
11198 2004-11-17 Akim Demaille <akim@epita.fr>
11200 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
11201 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
11202 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
11203 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11205 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
11207 * data/glr.c (yyloc_default): Remove; not used.
11208 Problem reported by Frank Heckenbach.
11210 2004-10-25 Akim Demaille <akim@epita.fr>
11212 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
11213 Introduce another definition to address simple location arrays.
11214 (yyGLRStack): New member: yyerror_range.
11215 (yyrecoverSyntaxError, yyparse): Update it.
11216 (yyrecoverSyntaxError): Use it when shifting the error token to
11217 have an accurate range, equivalent to the one computed by both
11218 yacc.c and lalr1.cc.
11219 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
11220 that column numbers start at column 0, as per GNU Coding
11221 Standards, the others tests, and the doc.
11222 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
11223 Adjust to the above change (first column is 0).
11224 And adjust the location of the "<error>", now covering the whole
11227 2004-10-22 Akim Demaille <akim@epita.fr>
11228 and Paul Eggert <eggert@cs.ucla.edu>
11230 Remove some arbitrary limits on goto numbers and relations.
11231 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
11232 initial values, since they're never used.
11233 (set_goto_map): ngotos is now unsigned, so test for overflow
11234 by seeing whether it wraps around to zero.
11235 * src/lalr.h (goto_number): Now size_t, not short int.
11236 (GOTO_NUMBER_MAXIMUM): Remove.
11237 * src/relation.c (relation_print, traverse, relation_transpose):
11238 Check for END_NODE rather than looking at sign.
11239 * src/relation.h (END_NODE): New macro.
11240 (relation_node): Now size_t, not short int.
11242 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
11244 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
11245 keyword, not an identifier. Problem reported by Baron Schwartz in
11246 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
11248 2004-10-11 Akim Demaille <akim@epita.fr>
11250 * src/symtab.c (symbol_check_alias_consistency): Also check
11251 type names, destructors, and printers.
11252 Reported by Alexandre Duret-Lutz.
11253 Recode the handling of associativity and precedence in terms
11254 of symbol_precedence_set.
11255 Accept no redeclaration at all, not even equal to the previous
11257 (redeclaration): New.
11258 Use it to factor redeclaration complaints.
11259 (symbol_make_alias): Don't set the type of the alias, let
11260 symbol_check_alias_consistency do it as for other features.
11261 * src/symtab.h (symbol): Add new member prec_location, and
11263 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
11264 * tests/input.at (Incompatible Aliases): New.
11266 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
11268 .cvsignore fixes to accommodate gnulib changes,
11269 and the practice of naming build directories "_build".
11270 * .cvsignore: Add "_*". Sort.
11271 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
11272 * m4/.cvsignore: Add "*_gl.m4".
11274 2004-10-06 Akim Demaille <akim@epita.fr>
11276 * src/parse-gram.y (add_param): Fix the truncation of trailing
11279 2004-10-05 Akim Demaille <akim@epita.fr>
11281 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11282 whether the reducion was empty or not. This leaves room to
11283 improve the use of YYLLOC_DEFAULT in such a case.
11284 lalr1.cc is still experimental, so changing this is acceptable.
11285 And finally, there are probably not many users who changed the
11286 handling of locations in GLR, so changing is admissible too.
11288 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
11289 empty reduction, set @$ to an empty location ending the previously
11291 Adjust uses to make sure the code is triggered on empty
11293 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
11294 expected output: empty reductions have empty locations.
11296 2004-09-29 Akim Demaille <akim@epita.fr>
11298 * data/lalr1.cc: Move towards a more standard C++ coding style
11299 for templates: Class < T > -> Class<T>.
11301 2004-09-29 Akim Demaille <akim@epita.fr>
11303 * data/lalr1.cc: Reinstall the former ctor, for sake of
11304 compatibility, but warn it will be removed.
11305 Move towards a more standard C++ coding style (i.e., type *var ->
11308 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
11310 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
11311 since it's less likely to work if NULs are involved in the future.
11313 2004-09-27 Akim Demaille <akim@epita.fr>
11315 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
11317 2004-09-27 Akim Demaille <akim@epita.fr>
11319 * data/lalr1.cc (b4_parse_param_decl_1): New.
11320 (b4_parse_param_decl): Use it to have different names between attribute
11321 and argument names.
11322 (b4_cc_constructor_call): Likewise.
11324 2004-09-24 Akim Demaille <akim@epita.fr>
11326 * src/parse-gram.y (add_param): Strip the leading and trailing
11327 blanks from a formal argument declaration.
11328 (YY_LOCATION_PRINT): New.
11330 2004-09-24 Akim Demaille <akim@epita.fr>
11332 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
11333 after the location.
11335 2004-09-24 Akim Demaille <akim@epita.fr>
11337 * doc/bison.texinfo (Table of Symbols): Sort.
11339 2004-09-21 Akim Demaille <akim@epita.fr>
11341 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
11342 the useless parentheses.
11343 Suggested by Paul Eggert.
11345 2004-09-20 Akim Demaille <akim@epita.fr>
11347 Let the initial-action act on the look-ahead, and use it for the
11348 "initial push" (corresponding to an hypothetical beginning-of-file).
11349 And let lalr1.cc honor %initial-action.
11351 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
11353 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
11354 (Parser::Parser): Remove the ctor that used to initialize it.
11355 (Parser::parse): Like in the other skeletons, issue the "starting
11356 parse" message before any action.
11357 Honor %initial-action.
11358 Initialize the stacks with the lookahead.
11359 * data/yacc.c: Let $$ and @$ in %initial-action designate the
11361 Push them in the stacks.
11362 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
11364 2004-09-20 Akim Demaille <akim@epita.fr>
11366 * doc/bison.texinfo (Initial Action Decl): New.
11368 2004-09-20 Akim Demaille <akim@epita.fr>
11370 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
11371 clearer criterion to define it.
11372 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
11373 When reducing on an empty RHS, use the latest stacked location as
11375 yylloc is not always available.
11376 * data/glr.c: Likewise.
11377 Also, honor initial-actions.
11379 2004-09-20 Akim Demaille <akim@epita.fr>
11381 * data/yacc.c (YY_LOCATION_PRINT): New.
11382 Define when we know YYLTYPE's structure, i.e., when the default
11383 YYLLOC_DEFAULT is used.
11384 * data/c.m4 (b4_yysymprint_generate): Use it.
11385 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
11386 value of the result.
11387 (error_start_): Replace with...
11388 (error_range_): this location array.
11389 This allows to replace code relying on the implementation of
11390 locations by portable code.
11391 * data/yacc.c (yylerrsp): Replace with...
11392 (yyerror_range): this.
11393 Every time a token is popped, update yyerror_range[0], to have an
11394 accurate location for the error token.
11395 * data/glr.c (YY_LOCATION_PRINT): New.
11396 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
11397 deference a pointer.
11398 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
11399 report the location in %printers.
11401 * src/scan-skel.l: Instead of abort, report error messages to ease
11402 understanding skeleton scanning failures.
11404 2004-09-16 Akim Demaille <akim@epita.fr>
11406 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
11407 (iterator, const_iterator): these, to be more in the C++ spirit.
11408 Also, return reverse iterators so that when displaying the stack
11409 we display its bottom first.
11410 (Parser::stack_print_, Parser::reduce_print_): Match the messages
11412 We should probably use vector here though.
11414 2004-09-16 Akim Demaille <akim@epita.fr>
11416 Have more complete shift traces.
11418 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
11419 to report Shifts instead of ad hoc YYDPRINTF invocations,
11420 including for the error token.
11421 * data/lalr1.cc (symprint_): Output the location.
11422 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
11423 output the location within the %printer.
11424 Activate GLR tests, at least to make sure they compile properly.
11425 They still don't pass though.
11426 * tests/calc.at: Adjust expect verbose output, since now "Entering
11427 state..." is on a different line than the "Shifting" message.
11429 2004-09-08 Akim Demaille <akim@epita.fr>
11431 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
11432 Bison directive from the Bison file to the invocation of this
11433 macro, so that these directives are passed to
11434 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
11435 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
11436 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11437 the extra Bison directives instead of the whole series.
11438 Change the grammar so that there are recoverable errors, and
11439 unrecoverable errors. Now we can have the parser give up before
11440 consuming the whole input. As a result we now can observe that
11441 the lookahead is freed when needed.
11442 Change the parser source to parse argv[1] instead of a hard coded
11444 Simplify yylex, and give a value and location to EOF.
11445 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11446 passed directives already coded in the file.
11447 Add some tests to check the location of "error".
11448 For some tests, the C++ parser is correct, and not yacc.c.
11449 For other tests, they provide different, but unsatisfying, values,
11450 so keep the C++ value so that at least one parser is "correct"
11451 according to the test suite.
11452 (Actions after errors): Remove, this is subsumed by the
11453 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
11455 2004-09-06 Akim Demaille <akim@epita.fr>
11457 * data/lalr1.cc: Adjust the indentation of the labels.
11458 (Parser::pop): New.
11461 2004-09-06 Akim Demaille <akim@epita.fr>
11463 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
11464 argument, an informative message.
11465 Call YY_SYMBOL_PRINT.
11466 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
11467 * data/lalr1.cc (destruct_): Likewise.
11468 In addition, no longer depend on b4_yysymprint_generate and
11469 b4_yydestruct_generate to generate these functions, do it "by
11472 2004-09-03 Akim Demaille <akim@epita.fr>
11474 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
11475 invoked, yydestruct the lookahead.
11476 * tests/calc.at (Calculator $1): Update the expected lengths of
11477 traces: there is an added line for the discarded lookahead.
11478 * doc/bison.texinfo (Destructor Decl): Some rewording.
11479 Define "discarded" symbols.
11481 2004-09-02 Akim Demaille <akim@epita.fr>
11483 * data/lalr1.cc (translate_, destruct_): No reason to be static.
11485 2004-09-02 Akim Demaille <akim@epita.fr>
11487 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
11488 (YYDSYMPRINTF): Rename as...
11489 (YY_SYMBOL_PRINT): this.
11490 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
11492 Use it instead of direct symprint_ calls.
11493 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
11496 2004-09-02 Akim Demaille <akim@epita.fr>
11498 * data/lalr1.cc (b4_yysymprint_generate): New.
11499 (symprint_): New member function, defined when YYDEBUG.
11500 Use it consistently instead of token/nterm debugging output by
11502 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
11503 %printer calls to use cdebug_ when using lalr1.cc.
11505 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
11507 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
11508 with #ifdef YYDEBUG.
11510 2004-08-26 Akim Demaille <akim@epita.fr>
11512 * doc/bison.texinfo (Implementing Loops): Rename as...
11513 (Implementing Gotos/Loops): this.
11515 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
11517 Adjust to latest gnulib.
11518 * bootstrap (gnulib_modules): Add xalloc-die.
11519 Set LC_ALL=C so that file names sort consistently.
11520 Prefer the gnulib copies of gettext.m4, glibc21.m4,
11521 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
11522 uintmax_t.m4, ulonglong.m4.
11523 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
11524 po.m4 since we are now using _gl.m4 instead.
11526 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
11528 * src/scan-action.l: Remove. Scanning of semantic actions is
11529 handled in scan-gram.l.
11531 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
11533 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
11535 * src/location.h (struct): The file member is a uniqstr.
11536 (equal_boundaries): Use UNIQSTR_EQ for comparison.
11538 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
11540 Fix bug with non-%union parsers that have printers or destructors,
11541 which led to a Bison core dump. Reported by Peter Fales in
11542 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
11544 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
11545 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
11546 not to our own type.
11547 * src/output.c (symbol_destructors_output, symbol_printers_output):
11548 Don't assume %union.
11549 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
11550 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
11551 UNION-FLAG. All callers changed.
11552 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
11553 Use type char, not unsigned int, when declaring an array of char;
11554 this lets us remove a cast.
11555 (Printers and Destructors): Add non-%union test cases.
11557 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11559 * doc/bison.texinfo: Minor editorial changes, mostly to the new
11560 GLR writeups. E.g., avoid frenchspacing and the future tense,
11561 change "lookahead" to "look-ahead", and change "wrt" to "with
11564 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11566 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
11567 New sections, split off from the GLR Parsers section. Put the new
11568 Simple GLR Parser near the start of the GLR section, for clarity.
11569 Rewrite connective text.
11571 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
11573 * doc/bison.texinfo (Simple GLR Parsers): New section.
11575 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11577 * NEWS, TODO, doc/bison.texinfo:

11609 * tests/atlocal.in (CXXFLAGS): Use it.
11611 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>

11627 C++ compiler. (trivial change)
11629 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
11631 Spent a few hours checking out which prerequisite versions the
11632 current sources actually require. I went all the way back to
11633 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
11634 a seemingly endless set of combinations of versions more recent
11635 than that. The bottom line is that the current sources require
11636 fairly recent versions of the build tools, and it'll be some work
11638 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
11639 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
11640 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
11641 Add comments explaining why those particular versions are
11644 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
11645 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
11646 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
11648 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
11649 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
11651 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11653 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
11654 0.11.5. Suggested by Bruno Haible.
11655 * bootstrap: Remove gettext version checking.
11657 * doc/bison.texinfo (Decl Summary): Also mention that %union
11658 can depend on prerequisite types. Problem reported by Tim
11661 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11663 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
11664 * README-alpha: Don't tell people not to package this.
11666 * bootstrap: Don't assume $(...) works; use `...` instead.
11667 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
11670 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
11671 put into the -d output file, and mention what to do if YYSTYPE is
11672 defined as a macro.
11674 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11676 Undo change made earlier today: it caused autopoint to not bring
11677 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
11680 * bootstrap: Check that gettext version matches what's in
11681 configure.ac. Warn users to ignore robots.txt ERROR 404.
11682 * bootstrap: Undo today's earlier change (logged below).
11683 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
11685 The gettext version checking is causing more trouble than it's
11686 curing; remove it. Problem reported by Paul Hilfinger.
11688 * bootstrap: Issue a warning that one can expect a message
11689 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
11690 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
11692 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
11694 Ensure that the C++ compiler used for testing actually works on a
11695 simple test program; if not, skip the C++-related tests. Problem
11696 reported by Vin Shelton in:
11697 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
11699 * m4/cxx.m4: New file.

11704 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
11706 * data/glr.c (yylloc): Output this macro even if locations are not
11707 being generated, as the GLR parser needs it even in that case.
11708 Problem reported by Troy A. Johnson
11709 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
11711 * configure.ac (AC_INIT): Update to 1.875e.

11715 * NEWS: Version 1.875d.
11716 * configure.ac (AC_INIT): Likewise.
11717 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
11719 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
11720 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
11721 lalr1.cc runs afoul of the first, and the last two are no longer
11722 supported by GCC 3.4.0.
11723 * README: Mention GNU m4 1.4 or later; mention m4 patches.
11724 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
11726 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
11728 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
11729 unsigned int, for compatibility with latest gnulib hash module.

11739 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
11740 character and string literals.
11741 (unexpected_end): New function.
11742 (unexpected_eof): Use it.
11743 (unexpected_newline): New function.
11744 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
11747 * NEWS: Document %expect-rr.
11749 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
11750 Fix typo by replacing $1 with $option.
11751 Remove more 'intl'-related files.
11752 Don't DEFUN AM_INTL_SUBDIR twice.
11754 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
11755 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
11757 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
11758 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
11759 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
11760 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
11761 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
11762 * src/.cvsignore: Add *.output.
11764 * src/parse-gram.y: Put copyright notice inside %{ %} so it
11765 gets copied to the output file.
11767 2004-04-28 Paul Eggert <eggert@twinsun.com>
11769 Get files from the gnulib and po repositories, instead of relying
11770 on them being in our CVS. Upgrade to latest versions of gnulib
11773 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
11774 * bootstrap: Bootstrap from gnulib and po repositories.
11775 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11776 * README-cvs: Document these changes. Remove version numbers from
11777 mentions of build tools, since they change so often. Mention Flex.
11779 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
11780 (gl_USE_SYSTEM_EXTENSIONS): Add.
11781 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
11782 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
11784 (AC_ISC_POSIX): Remove; we no longer support this
11785 ancient OS, as it gets in the way of latest Autoconf & gnulib.
11786 (AC_HEADER_STDC): Remove: we now assume C89 or better.
11787 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
11788 Do not check for C89 headers, except for locale.h which is used
11789 by the Yacc library and must port to K&R hosts.
11790 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
11791 Do not check for C89 functions, except for setlocale which is
11792 used by the Yacc library.

11798 AM_GNU_GETTEXT): Remove; now done by:
11799 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
11800 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
11803 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
11804 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
11805 Define to empty, as gnulib.mk will do the rest for us.

11840 Remove, as these files are now generated automatically
11841 by bootstrap or automake.
11843 * po/ChangeLog: Remove: all but one entry was a duplicate
11844 of this file, and I moved that 2000-11-02 entry here.

11869 2004-04-27 Paul Eggert <eggert@twinsun.com>
11871 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
11872 case, as stos_ is now used by destructors due to the 2004-02-09
11875 Remove more K&R C support.
11876 * lib/libiberty.y (PARAMS): Remove. All uses removed.

11894 with latest obstack.h.
11895 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
11896 to procedure types, as obstack.h now does that for us.
11897 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
11899 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
11900 so that this include file can stand alone.
11901 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
11902 does this now. Include subpipe.h first after config.h, to
11903 test whether it can stand alone.
11905 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
11906 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
11907 unused declaration.
11909 * tests/synclines.at (%union synch line): Put a dummy member in
11910 the union, because empty unions aren't allowed in C. Caught
11913 2004-04-13 Jim Meyering <jim@meyering.net>
11915 * src/conflicts.c (conflicts_print): Correct format string typo:

11974 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
11976 Use expected_sr_conflicts in place of expected_conflicts.
11977 Warn if expected_rr_conflicts used in non-GLR parser.
11979 * doc/bison.texinfo: Add documentation for %expect-rr.
11981 2004-03-08 Paul Eggert <eggert@gnu.org>
11983 Add support for hex token numbers. Suggested by Odd Arild Olsen in
11984 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
11986 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
11988 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
11989 * src/scan-gram.l (scan_integer): New function.

11998 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
11999 compilers. This fixes a problem with Intel's C++ compiler being
12000 chatty, reported by Guido Trentalancia in
12001 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
12003 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
12005 Support %destructor and merge error locations in lalr1.cc.
12007 * data/lalr1.cc (b4_cxx_destruct_def): New macro.

12017 token so that it covers all the discarded tokens.
12018 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
12019 it can be called with `%skeleton "lalr1.cc"', and do that.
12021 2004-02-02 Paul Eggert <eggert@twinsun.com>
12023 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
12024 $(top_srcdir)/lib and ../lib. This fixes a bug reported
12025 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
12026 There's no need to mention top_builddir since Automake does that
12028 (INCLUDES): Remove, as Automake says it's obsolescent.
12029 Contents migrated into AM_CPPFLAGS as described above.
12030 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
12032 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12034 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
12035 (yyreportSyntaxError): Handle case where lookahead token is
12038 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12040 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
12041 resulting parsers are compilable with C++.
12043 2003-12-23 Paul Eggert <eggert@twinsun.com>
12045 * config/depcomp, config/install-sh: Sync with Automake 1.8.
12046 * src/output.c (output_skeleton): Rename local var.
12047 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
12048 Bison tokens, as this runs afoul of the 2003-10-07 change that
12049 disallowed NUL bytes in character constants or string literals.
12051 * tests/local.at: Require Autoconf 2.59's Autotest.
12052 * tests/testsuite.at: Don't include local.at, since we now assume
12053 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
12055 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
12056 multiple inclusion warnings.

12070 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
12071 if testsuite doesn't exist.
12073 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
12074 literals, unfortunately.
12075 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
12076 Complain about NUL bytes in character constants or string literals.
12078 2003-10-05 Paul Eggert <eggert@twinsun.com>
12080 * NEWS: Don't document %no-default-prec, as it's still
12082 * doc/bison.texinfo: Document %no-default-prec only if
12083 the defaultprec flag is set. Normally it's not.
12085 2003-10-04 Paul Eggert <eggert@twinsun.com>
12087 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
12088 non-modifiable lvalue, instead of a modifiable one.
12089 * doc/bison.texinfo (Actions): Document that $$ can
12090 be assigned to. Do not claim that $$ and $N are
12091 array element references: user code should not rely on this.

12105 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
12106 * src/print_graph.c (print_graph): Adjust.
12108 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
12109 and Paul Eggert <eggert@twinsun.com>

12129 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
12132 2003-08-26 Akim Demaille <akim@epita.fr>
12134 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
12135 "<\#" to avoid magic from Gnus when posting parts of this script.
12137 2003-08-26 Akim Demaille <akim@epita.fr>
12139 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
12140 (Parser::parse): here.
12141 Adjust: nerrs and errstatus is now replaced by...
12142 (Parser::nerrs_, Parser::errstatus_): New.
12144 2003-08-25 Akim Demaille <akim@epita.fr>
12146 * config/announce-gen, Makefile.cfg: New.
12147 * Makefile.am: Adjust.
12148 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
12149 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
12151 2003-08-25 Akim Demaille <akim@epita.fr>
12153 When reducing initial empty rules, Bison parser read an initial
12154 location that is not defined. This results in garbage, and that
12155 affects Bison's own parser. Therefore we need (i) to extend Bison
12156 to support a means to initialize this location, and (ii) to use
12157 this CVS Bison to fix CVS Bison's parser.
12159 * src/reader.h, reader.c (epilogue_augment): Remove, replace
12161 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.

12163 (%initial-action): New.
12164 (%error-verbose): Since we require CVS Bison, there is no reason
12166 * src/scan-gram.l: Adjust.
12167 * src/Makefile.am (YACC): New, to make sure we use our own parser.
12168 * data/yacc.c (yyparse): Use b4_initial_action.
12170 2003-08-25 Akim Demaille <akim@epita.fr>
12172 * doc/bison.texinfo: Don't promote stdout for error messages.
12174 2003-08-25 Akim Demaille <akim@epita.fr>
12176 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
12177 From Alexandre Duret-Lutz.

12193 2003-08-25 Akim Demaille <akim@epita.fr>
12195 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
12196 error recovery loops. This patch is based on
12197 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
12198 Also, augment the similarity between lalr1.cc and yacc.c.
12199 Note: the locations of error recovery rules are not correct yet.
12201 * data/lalr1.cc: Comment changes to augment the similarity between
12202 lalr1.cc and yacc.c.
12203 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
12204 (yyerrlab1): Remove, but where it used to be (now the bottom part of
12205 yyerrlab), when hitting EOF, pop the whole stack here instead of
12206 merely falling thru the default error handling mechanism.
12207 (yyerrorlab): New label, with the old contents of YYERROR,
12208 plus the following change: pop the stack of rhs corresponding
12209 to the production that invoked YYERROR. That is how Yacc
12210 behaves (required by POSIX).
12211 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
12214 2003-08-25 Akim Demaille <akim@epita.fr>
12216 Tune local.at so that people can "autom4te -l autotest calc.at -o
12217 calc" for instance, to extract a sub test suite.
12219 * tests/testsuite.at: Move the initialization, Autotest version
12220 requirement, and AT_TESTED invocation into...
12221 * tests/local.at: here.
12222 * tests/testsuite.at: Include it for compatibility with Autoconf
12224 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
12227 2003-08-04 Paul Eggert <eggert@twinsun.com>
12229 Rework code slightly to avoid gcc -Wtraditional warnings.
12230 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
12231 The returned value is now stored in *YY0. All callers changed.
12232 * src/output.c (merge_output): Adjust to the above change.
12234 2003-07-26 Paul Eggert <eggert@twinsun.com>
12236 * data/glr.c (YYASSERT): New macro.
12237 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
12238 yyresolveStates, yyprocessOneStack):
12239 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
12240 Derived from a suggestion by Frank Heckenbach.
12242 2003-07-25 Paul Eggert <eggert@twinsun.com>
12244 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
12245 for portability to K&R C (after ansi2knr, presumably). See
12246 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
12247 by Frank Heckenbach, though I have omitted the structure-initialization
12248 part of his glr-knr.diff patch since I recall that the Portable
12249 C Compiler didn't require that change.
12251 Let the user specify how to allocate and free memory.
12252 Derived from a suggestion by Frank Heckenbach in
12253 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
12254 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
12255 All uses of free, malloc, realloc changed to use these macros,
12256 and unnecessary casts removed.
12257 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
12259 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
12261 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
12262 use s.empty() rather than s == "" to test for empty string; see
12263 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
12266 2003-06-25 Akim Demaille <akim@epita.fr>
12268 * config/depcomp, config/install-sh: Update from masters.
12270 2003-06-20 Paul Eggert <eggert@twinsun.com>
12272 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
12273 and return properly parenthesized result.
12274 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
12275 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
12276 Remove unnecessary parentheses from uses.
12277 * doc/bison.texinfo (Location Default Action): Describe the
12278 conventions for parentheses.
12280 2003-06-19 Paul Eggert <eggert@twinsun.com>
12282 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
12283 yyreportTree): Do not assume that size_t is the same width as int,
12284 when printing sizes. Print sizes using an unsigned format.
12285 Problem reported by Frank Heckenbach in
12286 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
12288 Port to Forte Developer 7 C compiler.
12289 * data/glr.c (struct YYLTYPE): If locations are not being used,
12290 declare a single dummy member, as empty structs do not conform
12292 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
12293 the Forte Developer 7 C compiler complains that end-of-loop
12294 code is not reached.
12296 2003-06-17 Paul Eggert <eggert@twinsun.com>
12298 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
12299 avoid warnings from picky compilers about redefinition of PARAMS.
12301 2003-06-17 Paul Eggert <eggert@twinsun.com>
12305 * NEWS: Document 1.875b.
12307 * lib/bbitset.h: Do not include config.h; that's the includer's job.
12308 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
12309 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
12310 Don't use 'index' in comments, as it's a builtin fn on some hosts.
12311 * lib/bitset_stats.c: Include gettext.h unconditionally, as
12312 per recent gettext manual's suggestion.
12313 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
12314 Use prototypes, not old-style definitions.
12315 * lib/lbitset.c (lbitset_unused_clear): Likewise.

12327 (ATTRIBUTE_NORETURN): Remove.
12328 (ATTRIBUTE_UNUSED): Define unconditionally.
12330 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
12331 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
12332 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
12333 * lib/vbitset.c, lib/vbitset.h: New files.
12334 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
12335 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
12338 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
12339 `How Can I Reset @code{yyparse}', since texinfo does not allow
12340 arbitrary @ in node names.
12342 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
12343 shouldn't be needed according to the gettext 0.12.1 documentation
12344 but which seem to be needed anyway: codeset.m4 glibc21.m4
12345 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
12346 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

12350 * m4/.cvsignore: Add nls.m4, po.m4.
12352 Upgrade to CVS gnulib.
12353 * stdbool_.h: File renamed from stdbool.h.in.
12354 * configure.ac (AM_STDBOOL_H): Invoke this instead of
12356 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
12357 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
12358 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
12359 (MOSTLYCLEANFILES): New var.
12360 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
12361 (stdbool.h): New rule.

12367 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
12368 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
12369 the tests right now.
12370 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
12371 yyerror are declared before use; C99 requires this.
12373 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12375 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
12377 (yyrecoverSyntaxError): Correct the logic for setting and testing
12379 Correct comment on handling EOF.
12380 Allow states with only a default reduction, rather than failing
12381 (I can't quite reconstruct why these were not allowed before).
12383 Fixes to avoid problem that $-N rules in GLR parsers can cause
12384 buffer overruns, corrupting state.
12386 * src/output.c (prepare_rules): Output max_left_semantic_context
12388 * src/reader.h (max_left_semantic_context): New variable declaration.
12389 * src/scan-gram.l (max_left_semantic_context): Define.
12390 (handle_action_dollar): Update max_left_semantic_context.
12391 * data/glr.c (YYMAXLEFT): New definition.
12392 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
12393 (yyresolveAction): Ditto.
12395 Fixes to problems with location handling in GLR parsers reported by
12396 Frank Heckenbach (2003/06/05).
12398 * data/glr.c (YYLTYPE): Make trivial if locations not used.
12399 (YYRHSLOC): Add parentheses, and define only if locations used.
12400 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
12401 locations not used.
12402 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
12403 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
12405 * tests/cxx-type.at: Exercise location information; update tests
12406 to differentiate output with and without locations.
12407 Remove forward declarations of yylex and yyerror---caused errors
12408 because default YYLTYPE not yet defined.
12409 Change semantic actions to compute strings, rather than printing
12410 them directly (to test proper passing of semantics values). Change
12411 output to prefix notation and update test data and expected results.
12412 (yylex): Track locations.
12413 (stmtMerge): Return value rather than printing, and include arguments
12416 2003-06-03 Paul Eggert <eggert@twinsun.com>
12418 Avoid warnings generated by GCC 2.95.4 when Bison is
12419 configured with --enable-gcc-warnings.
12420 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,

12422 yy::Stack::operator[] (unsigned),
12423 yy::Stack::operator[] (unsigned) const,
12424 yy::Slice::operator[] (unsigned),
12425 yy::Slice::operator[] (unsigned) const):
12426 Rename local vars to avoid warnings.
12427 * tests/glr-regression.at (Improper handling of embedded actions
12428 and $-N in GLR parsers): Remove unused local variable from yylex.
12429 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
12430 (void) as arg when not pure, since we now assume C89 when building
12431 Bison. Pacify GCC by using parameter.
12433 2003-06-02 Paul Eggert <eggert@twinsun.com>
12435 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
12436 yy::Location::lines, yy::Location::columns): Rename arguments
12437 to avoid shadowing; this removes a warning generated by GCC 3.3.
12439 2003-06-01 Paul Eggert <eggert@twinsun.com>
12441 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
12442 to g++, as GCC 3.3 complains if you do it.
12443 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
12444 everything that WARNING_CFLAGS has, except omit warnings
12445 not suitable for C++.
12446 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
12447 * tests/atlocal.in (CXXFLAGS): New var.
12448 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
12450 Fix a GLR parser bug I reported in February; see
12451 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
12452 The problem was that GLR parsers did not conform to the C standard,
12453 because actions like { $1 = $2 + $3; } expanded to expressions
12454 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12455 to a local variable. The C standard says that expressions
12456 like (var = f ()) + (var = f ()) have undefined behavior.
12457 Another problem was that GCC sometimes issues warnings that
12458 yyfill and its parameters are unused.
12460 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12461 as possibly unused.
12462 (yyfill): New function.
12464 (yyuserAction): Change type of yynormal to bool, so that it matches
12465 the new yyfill signature. Mark it as possibly unused.
12468 Follow up on a bug I reported in February, where a Bison-generated
12469 parser can loop. Provide a test case and a fix for yacc.c. I
12470 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12471 The original bug report is in:
12472 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
12474 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12475 macro's size was becoming unwieldy.
12476 (yyerrlab): Do not discard an empty lookahead symbol, as this
12477 might destroy garbage.
12478 (yyerrorlab): New label, with the old contents of YYERROR,
12479 plus the following change: pop the stack of rhs corresponding
12480 to the production that invoked YYERROR. That is how Yacc
12481 behaves, and POSIX requires this behavior.
12482 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12483 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12484 Define 'alarm' to do nothing if unistd.h is not available.
12485 Add a new rule "exp: '-' error;" to test the above change to
12486 data/yacc.c. Use 'alarm' to abort any test taking longer than
12487 10 seconds, as it's probably looping.
12488 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12489 Also, the new yacc.c generates two fewer diagnostics for an
12492 2003-05-24 Paul Eggert <eggert@twinsun.com>
12494 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
12495 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
12496 This fixes a problem reported by John Bowman when the Compaq/HP
12497 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
12498 -ansi -Wall -gall).
12499 * data/yacc.c (union yyalloc): Likewise.
12500 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
12502 Switch from 'int' to 'bool' where that makes sense.

12565 2003-05-14 Paul Eggert <eggert@twinsun.com>
12567 * src/parse-gram.y (rules_or_grammar_declaration): Require a
12568 semicolon after a grammar declaration, in the interest of possible
12569 future changes to the Bison input language.
12570 Do not allow a stray semicolon at the start of the grammar.
12571 (rhses.1): Allow one or more semicolons after any rule, including
12572 just before "|" as required by POSIX.
12573 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
12576 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
12578 %parse-param support for lalr1.cc.
12580 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
12581 b4_cc_constructor_calls, b4_cc_constructor_call,
12582 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4

12586 (yy::b4_parser_class_name): Declare instance variables to

12588 * tests/calc.at: s/value/semantic_value/ because value clashes
12589 with a member of yy::b4_parser_class_name. Adjust C++ code

12592 2003-05-12 Paul Eggert <eggert@twinsun.com>
12594 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
12595 English a bit. Fix fclose typo. Change "const char" to "char
12596 const", and use ANSI C rather than K&R for "main". Suggest
12597 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
12598 and suggest yy_switch_to_buffer.
12600 2003-05-05 Paul Eggert <eggert@twinsun.com>
12602 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
12603 C89. This avoids a diagnostic on compilers that define __STDC__
12604 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
12605 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12607 2003-05-03 Paul Eggert <eggert@twinsun.com>
12609 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
12610 Do not overrun array bounds.
12611 This should fix a bug reported today by Olatunji Oluwabukunmi in
12612 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
12614 2003-04-29 Akim Demaille <akim@epita.fr>
12616 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
12617 * src/getargs.c, src/getargs.h: here, as bool, not int.
12618 (nondeterministic_parser): New.
12619 * src/parse-gram.y, src/scan-gram.l: Support
12620 %nondeterministic-parser.
12621 * src/output.c (prepare): Use nondeterministic_parser instead
12622 of glr_parser where appropriate.
12623 * src/tables.c (conflict_row, action_row, save_row)
12624 (token_actions, token_actions, pack_vector): Ditto.
12626 2003-04-29 Akim Demaille <akim@epita.fr>
12628 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
12630 2003-04-29 Akim Demaille <akim@epita.fr>
12632 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
12633 with %pure-parser and %locations to exercise the patch from Yakov
12636 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
12638 * data/yacc.c: (b4_lex_param): Corrected for the case where
12639 %lex-param is provided and %pure-parser isn't.
12641 2003-04-27 Paul Eggert <eggert@twinsun.com>
12643 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
12644 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
12645 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
12646 if it is not defined.
12647 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
12649 2003-04-26 Paul Eggert <eggert@twinsun.com>
12651 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
12652 Declare to be of type suitable for the ninf value itself, not of
12653 type suitable for the corresponding table, since the latter might
12654 be unsigned but the ninf value might be negative. This fixes a
12655 bug reported by Alexandre Duret-Lutz in
12656 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
12658 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
12659 invokes it. We shouldn't invoke it twice because it will attempt
12660 to put error.o in the archive twice. This fixes a glitch reported
12661 by Martin Mokrejs in
12662 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12664 2003-04-21 Paul Eggert <eggert@twinsun.com>
12666 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
12669 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
12671 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
12672 Fix obvious typo that results in uncompilable GLR parsers
12673 when both %pure-parser and %locations are used. (trivial change)
12675 2003-04-17 Paul Eggert <eggert@twinsun.com>
12677 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
12678 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
12679 Do not insert the expected token via unput, as this runs afoul
12680 of a POSIX-compatibility bug in flex 2.5.31.
12681 All uses changed to BEGIN the parent state,
12682 since we no longer insert the expected token via unput.
12683 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
12684 that is no longer emitted after the above change.
12686 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
12687 the first one. This change is from Paul Hilfinger, and it fixes
12688 regression reported by Werner Lemberg in
12689 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
12691 (resolve_sr_conflict): Don't invoke state_errs_set
12692 unless one or more tokens have been explicitly made errors.
12693 Otherwise, the above change causes Bison to abort.
12695 * tests/existing.at (GNU pic Grammar): New test case, taken from
12698 2003-03-31 Akim Demaille <akim@epita.fr>
12700 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
12702 2003-03-31 Akim Demaille <akim@epita.fr>
12704 * src/output.c (prepare_symbols): Avoid trailing spaces in the
12707 2003-03-31 Akim Demaille <akim@epita.fr>
12709 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
12710 From Paul Hilfinger.
12712 2003-03-29 Akim Demaille <akim@epita.fr>
12714 * m4/error.m4: Do not put under dynamic conditions some code which
12715 expansion is under static control.
12717 2003-03-29 Akim Demaille <akim@epita.fr>
12719 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
12721 2003-03-29 Akim Demaille <akim@epita.fr>
12723 * doc/bison.texinfo (Strings are Destroyed): New.
12725 2003-03-13 Paul Eggert <eggert@twinsun.com>
12727 * .cvsignore: Add configure.lineno.
12728 * src/.cvsignore: Add yacc.
12729 * tests/.cvsignore: Add testsuite.log.
12730 * doc/fdl.texi: Sync with latest FSF version.
12732 2003-03-12 Paul Eggert <eggert@twinsun.com>
12734 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
12735 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
12736 cursor, instead of leaving it undefined. This fixes a bug
12737 reported by Tim Van Holder in
12738 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
12739 * tests/input.at (Torturing the Scanner): Test the scanner on
12740 an empty input file, which was Tim Van Holder's test case.
12742 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
12743 <sys/resource.h> can be included, include sys/time.h and
12744 sys/times.h first, if available. This works around the SunOS
12745 4.1.4 porting bug reported by Bruce Becker in
12746 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
12748 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
12749 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
12750 AC_HEADER_SYS_WAIT.
12752 Merge changes from gnulib. This was prompted because the CVS
12753 snapshot didn't build on Solaris 7 due to strnlen problems.
12755 These changes need to be merged back into gnulib:
12756 * lib/hash.c: Include <stdbool.h> unconditionally.
12757 * m4/onceonly.m4 (m4_quote): New macro.
12758 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
12759 Quote AC_FOREACH variable-expansions properly.
12760 The 2003-01-03 obstack.h change also needs merging.
12761 {end of changes requiring merging}
12763 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
12764 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
12765 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
12766 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
12767 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
12768 New files, imported from gnulib.
12769 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
12772 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
12773 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
12776 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
12778 (gl_ERROR): New, replacing jm_PREREQ_ERROR.

12782 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
12783 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
12784 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
12785 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
12786 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
12787 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
12788 (jm_PREREQ_ARGMATCH): Remove.
12789 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
12790 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
12792 * src/system.h: Include <stdbool.h> unconditionally.
12794 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
12795 assuming at least C89 in the bitset code for some time now.
12797 2003-03-03 Akim Demaille <akim@epita.fr>
12801 2003-03-02 Akim Demaille <akim@epita.fr>
12803 * doc/bison.texinfo (Table of Symbols): Reactivate the
12804 documentation for %lex-param, and %parse-param.
12806 2003-03-02 Akim Demaille <akim@epita.fr>
12808 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
12809 generate verbose error messages.
12810 Use the number of tokens as an upper bound in yytname, as it
12811 cannot be a non terminal.
12813 2003-03-02 Akim Demaille <akim@epita.fr>
12815 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
12818 2003-03-02 Akim Demaille <akim@epita.fr>
12820 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
12821 Use them to exercise yycheck overrun.
12822 Based on Andrew Suffield's grammar.
12824 2003-03-02 Akim Demaille <akim@epita.fr>
12826 Create tests/local.at for Bison generic testing macros.
12828 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
12829 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):

12832 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
12833 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
12834 * tests/local.at: here.
12835 (AT_COMPILE_CXX): Tags the tests using it as c++.
12836 Ignore the test if CXX is not functional.
12838 2003-03-01 Paul Eggert <eggert@twinsun.com>
12840 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12841 not loc->end, since loc->end might contain garbage and this leads
12842 to undefined behavior on some platforms.
12843 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12844 depend on *loc, so that the reader doesn't give the the false
12845 impression that *loc is initialized.
12846 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12847 does not survive the return.
12849 2003-03-01 Akim Demaille <akim@epita.fr>
12851 * src/scan-gram.l (code_start): Always initialize it when entering
12852 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12853 yylex invocation. An alternative would be making it static, but
12854 then it starts with the second %%'s beginning, instead of its end.
12856 2003-02-28 Paul Eggert <eggert@twinsun.com>
12858 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12859 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12860 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12862 2003-02-26 Paul Eggert <eggert@twinsun.com>
12864 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12865 Remove Sequent/Pyramid discussion (nobody uses them any more).
12866 Merge VMS and MS-DOS discussion; these ports may well be dead
12867 but let's keep mentioning them for now. Put <> around email
12868 addresses. Add copyright notice.
12870 2003-02-24 Paul Eggert <eggert@twinsun.com>
12872 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12873 to avoid collision with flex use of yylineno.
12874 Problem reported by Bruce Lilly in
12875 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

12877 * data/yacc.c (yy_reduce_print): Likewise.
12879 * config/depcomp: Sync with Automake 1.7.3.
12881 2003-02-21 Akim Demaille <akim@epita.fr>
12883 * data/lalr1.cc: Use temporary variables instead of casts to
12884 change integer types.
12885 Suggested by Paul Eggert.
12887 2003-02-21 Akim Demaille <akim@epita.fr>
12889 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12890 to avoid confusions with lalr1.cc's notion of Position.
12891 Suggested by Paul Eggert.
12893 2003-02-20 Akim Demaille <akim@epita.fr>
12895 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12896 before initial_columns.
12897 (location.hh): Use consistent variable names when defining the
12899 Use "last" so that we subtract from Positions, not from unsigned.
12901 2003-02-20 Akim Demaille <akim@epita.fr>
12903 * data/lalr1.cc (position.hh): New subfile, including the extended
12904 and Doxygen'ed documentation of class Position.
12905 (location.hh): Use it.
12906 Document a` la Doxygen.
12907 With the help of Benoit Perrot.

12913 Redefine AT_YYERROR_SEES_LOC_IF using it.
12914 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
12916 Don't use the location in yy::Parser::error_ and
12917 yy::Parser::print_ when not %locations.
12918 Activate more lalr1.cc tests.
12920 2003-02-19 Akim Demaille <akim@epita.fr>
12922 * data/lalr1.cc: When displaying a line number, be sure to make it
12925 2003-02-19 Akim Demaille <akim@epita.fr>
12927 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12929 (YYABORT, YYACCEPT, YYERROR): New.
12930 * tests/calc.at: Renable the lalr1.cc test.
12932 2003-02-19 Akim Demaille <akim@epita.fr>
12934 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12935 error recovery, mixing with/without pops and discarding of the
12938 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
12940 2003-02-17 Paul Eggert <eggert@twinsun.com>
12942 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
12943 * tests/testsuite.at (AT_COMPILE): Use them.
12944 This fixes the testsuite problem reported by Robert Lentz in
12945 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
12947 2003-02-12 Paul Eggert <eggert@twinsun.com>
12949 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
12950 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in

12952 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12953 Check for malloc failure, for consistency with yacc.c.
12954 (yytname_size): Remove, for consistency with yacc.c.
12956 The bug still remains in data/lalr1.cc, as I didn't have time
12959 2003-02-06 Akim Demaille <akim@epita.fr>
12961 * configure.ac (GXX): Rename as...
12962 (CXX): this, to keep the original Autoconf semantics.

12981 Adjust the C locations to match those from Emacs: first column is
12983 Change all the expected results.
12984 Conform to the GCS: simplify the locations when applicable.
12985 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
12986 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
12987 these CPP macros with the m4 macros new defined by...

12992 (AT_CHECK_POPDEFS): Undefine them.
12993 (AT_CHECK_CALC_LALR1_CC): New.

13052 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13053 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13054 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
13055 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
13056 param to have same name as that of enum, so that we don't use
13057 "s" to stand for a non-state.
13059 2003-02-02 Akim Demaille <akim@epita.fr>
13061 * src/scan-skel.l: Scan more than one inert character per yylex
13064 2003-02-01 Paul Eggert <eggert@twinsun.com>
13068 * po/LINGUAS: Add ms.
13070 2003-01-30 Akim Demaille <akim@epita.fr>
13072 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
13074 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13076 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
13079 Changes in response to error report by S. Eken: GLR mode does not
13080 handle negative $ indices or $ indices in embedded rules correctly.
13081 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
13083 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
13084 (b4_rhs_location): Ditto.
13085 (yyfill): New function to copy from stack tree into array
13087 (yyuserAction): Modify to allow incremental move of semantic values
13088 to rhs array when in GLR mode.
13089 Define YYFILL to use in user-defined actions to fill semantic array
13091 Remove dummy use of yystack, as there is now a guaranteed use.
13092 (yydoAction): Modify to allow incremental move of semantic values
13093 to rhs array when in GLR mode.
13094 (yyresolveAction): Ditto.
13095 (yyglrShiftDefer): Update comment.
13096 (yyresolveStates): Use X == NULL for pointers, not !X.
13097 (yyglrReduce): Ditto.
13098 (yydoAction): Ditto
13100 * tests/glr-regr1.at: Rename to ...
13101 * tests/glr-regression.at: Add new regression test for the problems
13102 described above (adapted from S. Eken).
13103 Update copyright notice.
13104 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
13105 * tests/Makefile.am: Ditto.
13107 2003-01-28 Paul Eggert <eggert@twinsun.com>
13109 * data/lalr1.cc: Do not use @output_header_name@ unless
13110 b4_defines_flag is set. This fixes two bugs reported by
13112 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
13113 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
13115 2003-01-21 Paul Eggert <eggert@twinsun.com>
13117 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
13118 we don't need to worry about yyerrlab1 being reported as an
13119 "unused label" by non-GCC C compilers. The downside is that if
13120 locations are used then a couple of statements are duplicated each
13121 time YYERROR is invoked, but the upside is that the warnings
13123 (yyerrlab1): Move code to YERROR.
13124 (yyerrlab2): Remove. Change uses back to yyerrlab1.
13125 This reverts some of the 2002-12-27 change.
13127 2003-01-17 Paul Eggert <eggert@twinsun.com>
13129 * src/output.c (symbol_printers_output): Fix typo that led
13130 to core dump. Problem reported by Antonio Rus in
13131 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
13133 2003-01-13 Akim Demaille <akim@epita.fr>,
13134 Quoc Peyrot <chojin@lrde.epita.fr>,
13135 Robert Anisko <anisko_r@lrde.epita.fr>
13137 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
13138 when the stacks contain one element, as the loop would otherwise
13139 free the last state, and then use the top state (the one we just
13140 popped). This means that the initial elements will not be freed
13141 explicitly, as is the case in yacc.c; it is not a problem, as
13142 these elements have fake values.
13144 2003-01-11 Paul Eggert <eggert@twinsun.com>
13146 * NEWS: %expect-violations are now just warnings, reverting
13147 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
13148 bootstrapping problem reported by Matthias Klose; see
13149 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
13150 * src/conflicts.c (conflicts_print): Likewise.
13151 * tests/conflicts.at (%expect not enough, %expect too much,
13152 %expect with reduce conflicts): Likewise.
13153 * doc/bison.texinfo (Expect Decl): Document this. Also mention
13154 that the warning is enabled if the number of conflicts changes
13155 (not necessarily increases).
13157 * src/getargs.c (version): Update copyright year.
13159 2003-01-09 Akim Demaille <akim@epita.fr>
13161 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
13163 2003-01-08 Paul Eggert <eggert@twinsun.com>
13165 * Makefile.maint (WGETFLAGS):
13166 New macro, containing "-C off" to disable proxy caches.
13167 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
13168 (rel-check): Use $(WGET) instead of wget.
13170 2003-01-06 Paul Eggert <eggert@twinsun.com>
13172 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
13173 the GLR paper of Scott, Johnstone and Hussain.
13175 2003-01-04 Paul Eggert <eggert@twinsun.com>
13177 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
13178 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
13179 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
13180 (EXTRA_LIBRARIES): New var, for liby.a.
13181 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
13182 (EXTRA_SCRIPTS): New var, for yacc.
13184 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
13185 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
13186 Problem reported by Nelson H. F. Beebe.
13188 2003-01-03 Paul Eggert <eggert@twinsun.com>
13190 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
13191 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
13192 when compiling Bison 1.875's `bitset bset = obstack_alloc
13193 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
13195 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
13196 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
13197 grow to a huge size with typical invocation.
13199 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
13200 Use the pattern recommended by Autoconf 2.57, except also protect
13201 against double-definition.
13202 * src/system.h: Likewise.
13203 Portability issues reported by Nelson H. F. Beebe.
13205 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
13206 All uses changed. Provide a definition in both C and C++.
13207 (yytrue, yyfalse): Define even if defined (__cplusplus).
13209 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
13210 Reported by Nelson H. F. Beebe.
13212 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
13214 2003-01-02 Paul Eggert <eggert@twinsun.com>
13216 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
13217 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
13218 Bug reported by Nelson H. F. Beebe.
13220 2003-01-01 Paul Eggert <eggert@twinsun.com>
13224 2002-12-30 Paul Eggert <eggert@twinsun.com>
13226 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
13228 (<INITIAL>","): Here. This causes stray "," to be treated
13231 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
13232 last brace in braced code when not in Yacc mode, for compatibility
13233 with Bison 1.35. This resurrects the 2001-12-15 patch to
13236 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
13237 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
13239 2002-12-28 Paul Eggert <eggert@twinsun.com>
13241 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
13242 that of SYM's type. This fixes Debian bug 168069, reported by
13245 2002-12-28 Paul Eggert <eggert@twinsun.com>
13249 Switch back to the Yacc style of conflict reports, undoing some
13250 of the 2002-07-30 change.
13251 * doc/bison.texinfo (Understanding): Use Yacc style for
13252 conflict reports. Also, use new way of locating rules.
13253 * src/conflicts.c (conflict_report):
13254 Renamed from conflict_report_yacc, removing the old
13255 'conflict_report'. Translate the entire conflict report at once,
13256 so that we don't assume that "," has the same interpretation in
13258 (conflicts_output): Use Yacc-style conflict report for each state,
13259 instead of our more-complicated style.
13260 (conflicts_print): Use Yacc-style conflict report, except print
13261 the input file name when not emulating Yacc.
13262 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
13263 Conflicted Reduction, %expect not enough, %expect too much,
13264 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
13265 * tests/existing.at (GNU Cim Grammar): Likewise.
13266 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
13268 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
13269 fatal): Don't invoke fflush; it's not needed and it might even be
13270 harmful for stdout, as stdout might not be open.
13271 * src/reduce.c (reduce_print): Likewise.
13273 2002-12-27 Paul Eggert <eggert@twinsun.com>
13275 Fix a bug where error locations were not being recorded correctly.
13276 This problem was originally reported by Paul Hilfinger in
13277 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
13279 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13280 top of the location stack's error locations.
13281 (yyerrlab): Set it. When discarding a token, push its location
13282 onto yylerrsp so that we don't lose track of the error's end.
13283 (yyerrlab1): Now is only the target of YYERROR, so that we can
13284 properly record the location of the action that failed. For GCC
13285 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13286 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13287 (yyerrlab2): New label, which yyerrlab now falls through to.
13288 Compute the error's location by applying YYLLOC_DEFAULT to
13289 the locations of all the symbols that went into the error.
13290 * doc/bison.texinfo (Location Default Action): Mention that
13291 YYLLOC_DEFAULT is also invoked for syntax errors.
13292 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13293 Error locations include the locations of all the tokens that were
13294 discarded, not just the last token.
13296 2002-12-26 Paul Eggert <eggert@twinsun.com>
13298 * src/files.c: Include quote.h.
13299 (compute_output_file_names): Warn if we detect conflicting
13300 outputs to the same file. This should catch the misunderstanding
13301 exemplified by Debian Bug 165349, reported by Bruce Stephens..
13303 * src/conflicts.c (conflicts_print): If the user specifies
13304 "%expect N", report an error if there are any reduce/reduce
13305 conflicts. This is what the manual says should happen.
13306 This fixes Debian bug 130890, reported by Anthony DeRobertis.
13307 * tests/conflicts.at (%expect with reduce conflicts): New test.
13309 Don't use m4_include on relative file names, as it doesn't work as
13310 desired if there happens to be a file with that name under ".".
13312 * m4sugar/version.m4: Remove; it was included but it wasn't used.
13313 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
13314 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
13315 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
13316 * src/output.c (output_skeleton): Use full path names when
13317 specifying a file to include; don't rely on include path, as
13318 it's unreliable when the working file contains a file with
13321 2002-12-25 Paul Eggert <eggert@twinsun.com>
13323 Remove obsolete references to bison.simple and bison.hairy.
13324 Problem mentioned by Aubin Mahe in
13325 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
13326 * data/glr.c: Comment fix.
13327 * doc/bison.1: Remove references. Also, mention "yacc".
13329 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
13332 * src/parse-gram.y (declaration): Use enum "report_states" rather
13333 than its numeric value 1.
13335 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
13336 opening a new one. This fixes Debian bug 165349, reported by
13339 2002-12-24 Paul Eggert <eggert@twinsun.com>
13343 * Makefile.maint (cvs-update): Don't assume that the shell
13344 supports $(...), as Solaris sh doesn't.
13346 * src/parse-gram.y (lloc_default): Remove test for empty
13347 nonterminals at the end, since it didn't change the result.
13349 2002-12-24 Paul Eggert <eggert@twinsun.com>
13351 If the user does not define YYSTYPE as a macro, Bison now declares it
13352 using typedef instead of defining it as a macro. POSIX requires this.
13353 For consistency, YYLTYPE is also declared instead of defined.
13355 %union directives can now have a tag before the `{', e.g., the
13356 directive `%union foo {...}' now generates the C code
13357 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13358 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13359 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13360 instead of `yyltype'.
13362 `yystype' and `yyltype' are now obsolescent macros instead of being
13363 typedefs or tags; they are no longer documented and will be
13364 withdrawn in a future release.
13366 * data/glr.c (b4_location_type): Remove.
13367 (YYSTYPE): Renamed from yystype.
13368 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
13369 (struct YYLTYPE): Renamed from struct yyltype.
13370 (YYLTYPE): Renamed from yyltype.
13371 (yyltype, yystype): New (and obsolescent) macros,
13372 for backward compatibility.
13373 * data/yacc.c: Likewise.
13375 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13376 does not specify a union tag. This is for compatibility with
13379 * src/parse-gram.y (add_param): 2nd arg is now char * not char
13380 const *, since it is now modified by stripping surrounding { }.
13381 (current_braced_code): Remove.
13382 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
13383 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
13384 trailing " {...}". Now of type <chars>.
13385 (grammar_declaration): Adjust to bundled tokens.
13386 (code_content): Remove; stripping is now done by add_param.
13387 (print_token_value): Print contents of bundled tokens.
13388 (token_name): New function.
13390 * src/reader.h (braced_code, current_braced_code): Remove.
13391 (token_name): New decl.
13393 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
13394 token_type, not braced_code code_kind. All uses changed.
13395 (SC_PRE_CODE): New state, for scanning after a keyword that
13396 has (or usually has) an immediately-following braced code.
13397 (token_type): New local var, to keep track of which token type
13398 to return when scanning braced code.
13399 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
13400 <INITIAL>"%parse-param", <INITIAL>"%printer",
13401 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
13402 instead of returning a token type immediately.
13403 (<INITIAL>"{"): Set token type.
13404 (<SC_BRACED_CODE>"}"): Use it.
13405 (handle_action_dollar, handle_action_at): Now returns bool
13406 indicating success. Fail if ! current_rule; this prevents a core dump.
13407 (handle_symbol_code_dollar, handle_symbol_code_at):
13408 Remove; merge body into caller.
13409 (handle_dollar, handle_at): Complain in invalid contexts.
13411 * NEWS, doc/bison.texinfo: Document the above.
13412 * NEWS: Fix years and program names in copyright notice.
13414 2002-12-17 Paul Eggert <eggert@twinsun.com>
13416 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
13417 Reporting, Table of Symbols): Omit mentions of %lex-param and
13418 %parse-param from the documentation for now.
13420 2002-12-15 Paul Eggert <eggert@twinsun.com>
13422 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
13423 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
13424 lookahead symbol, and which sets yychar in parser actions) and it
13425 disagreed with the Bison documentation. Bug
13426 reported by Andrew Walrond.
13428 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
13429 as the caller now does that.
13430 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
13431 (YYEMPTY): Parenthesize right hand side, since others use it.
13432 (yyparse): Don't assume that our generated code is the only code
13435 2002-12-13 Paul Eggert <eggert@twinsun.com>
13439 POSIX requires a "yacc" command.
13440 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
13441 (MOSTLYCLEANFILES): Add yacc.
13443 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
13444 as an alias for bison y.
13446 * po/LINGUAS: Add da.
13448 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
13449 problem with latest <getopt.h>.
13450 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
13452 * doc/fdl.texi: Upgrade to 1.2.
13453 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
13454 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
13455 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
13457 * config/install-sh: Sync with autotools.
13459 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
13460 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13461 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
13462 locations are requested.
13463 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
13464 locations are requested.
13466 2002-12-12 Paul Eggert <eggert@twinsun.com>
13468 Remove unportable casts and storage allocation tricks.
13469 While we're at it, remove almost all casts, since they
13470 usually aren't needed and are a sign of trouble.
13472 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13474 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13475 the pointer DSET returned by malloc; this isn't portable.
13476 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13477 Similarly for DERIVES.
13478 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
13479 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
13480 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
13482 * src/derives.c (derives_compute): Do not bother invoking
13483 int_of_rule_number, since rule numbers are integers.
13485 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
13486 rather than XMALLOC (char, N).
13488 * src/files.c (filename_split): Rewrite to avoid cast.
13490 * src/gram.h (symbol_number_as_item_number,
13491 item_number_as_symbol_number, rule_number_as_item_number,
13492 item_number_as_rule_number):
13493 Now inline functions rather than macros, to avoid casts.
13494 * src/state.h (state_number_as_int): Likewise.
13495 * src/tables.c (state_number_to_vector_number,
13496 symbol_number_to_vector_number): Likewise.
13498 * src/gram.h (int_of_rule_number): Remove; no longer used.
13500 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
13501 since the resulting storage is always stored into.
13503 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
13506 * src/muscle_tab.c (muscle_m4_output):
13507 Now inline. Return bool, not int.
13508 * src/state.c (state_compare): Likewise.

13521 * src/uniqstr.c (uniqstr_print_processor): Likewise.
13522 * src/muscle_tab.c (muscles_m4_output):
13523 Use new functions instead of casting old functions unportably.

13526 symbols_token_translations_init):
13528 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
13530 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13531 var instead of casting to long, to avoid casts.
13532 (prepare_states): Use MALLOC rather than alloca, so that we don't
13533 have to worry about alloca.
13534 * src/state.c (state_hash_lookup): Likewise.
13536 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
13537 local var instead of casting to unsigned char, to avoid casts.

13540 STATE_ALLOC): Remove.
13541 (transitions_new, errs_new, reductions_new, state_new): Use malloc

13546 * src/state.c (state_hash): Use unsigned accumulator, not signed.
13548 * src/symtab.c (symbol_free): Remove; unused.

13554 (symbol_processor): Remove.
13555 (symbols_do): Remove decl; now static.

13559 (<inttypes.>, <stdint.h>): Include if available.
13560 (uintptr_t): New type, if system lacks it.
13561 (CALLOC, MALLOC, REALLOC): New macros.
13562 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
13565 * src/tables.c (table_size): Now int, to pacify GCC.

13578 2002-12-09 Paul Eggert <eggert@twinsun.com>
13580 Change identifier spellings to avoid collisions with names
13581 that are reserved by POSIX.
13583 Don't use names ending in _t, since POSIX reserves them.
13584 For consistency, remove _e and _s endings -- they're weren't
13585 needed to remove ambiguity. All uses changed.
13586 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
13587 turn was just renamed from struniq_t.
13588 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
13589 which in turn was just renamed from struniq_processor_t.

13661 value_t_as_yystype -> value_as_yystype.
13663 Don't include <errno.h> in the mainstream code, since it
13664 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
13665 * lib/get-errno.c, lib/get-errno.h: New files.
13666 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

13676 (TAB_EXT): Renamed from EXT_TAB.

13681 likewise for "STRUNIQ" and "UNIQSTR".
13682 * src/uniqstr.c: Renamed from src/struniq.c.
13683 * src/uniqstr.h: Renamed from src/struniq.h.
13684 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

13694 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.

13707 (ACTION_MAX): Remove; unused.
13708 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
13709 Unnecessary casts removed from above defines.
13712 Fix misspelling in names.
13713 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
13714 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
13718 * lib/timevar.c (timevar_report): Renamed from time_report,
13719 for consistency with other names.

13721 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
13724 Sort include-file uses.
13726 Reorder all include files under src to be in the order "system.h".
13727 then the ../lib include files in angle brackets (alphabetized),
13728 then the . include files in double-quotes (alphabetized). Fix
13729 dependency breakages encountered in this process, as follows:
13730 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
13731 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
13732 * src/state.h: Include "symtab.h".
13734 2002-12-08 Paul Eggert <eggert@twinsun.com>
13736 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
13737 since this causes problems when __file__ contains character
13738 sequences like "@" that are treated specially by src/scan-skel.l.
13739 Instead, just use the file's basename. This fixes the bug
13740 reported by Martin Mokrejs in
13741 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
13743 2002-12-06 Paul Eggert <eggert@twinsun.com>
13745 Add support for rules that do not have trailing semicolons, as
13746 POSIX requires. Improve the quality of locations in Bison
13749 * src/location.c: Include <quotearg.h>.
13750 (empty_location): Now const.
13751 (location_print): New function. Follow the recommendation of the
13752 GNU Coding Standards for locations that span file boundaries.
13753 * src/location.h: Do not include <quotearg.h>; no longer needed.
13754 (boundary): New type.
13755 (location_t): Use it. This allows locations to span file boundaries.
13756 All member uses changed: file -> start.file or end.file (as needed),
13757 first_line -> start.line, first_column -> start.column,
13758 last_line -> end.line, last_column -> end.column.
13759 (equal_boundaries): New function.
13760 (LOCATION_RESET, LOCATION_STEP): Remove.
13761 (LOCATION_PRINT): Remove. All callers changed to use location_print.
13762 (empty_location): Now const.
13763 (location_print): New decl.
13764 * src/parse-gram.y (lloc_default): New function, which handles
13765 empty locations more accurately.
13766 (YYLLOC_DEFAULT): Use it.
13767 (%token COLON): Remove.
13768 (%token ID_COLON): New token.
13770 (declarations, rules): Remove trailing semicolon.
13771 (declaration, rules_or_grammar_declaration):
13772 Allow empty (";") declaration.
13773 (symbol_def): Remove empty actions; no longer needed.
13774 (rules_or_grammar_declaration): Remove trailing semicolon.
13775 (semi_colon.opt): Remove.
13776 * src/reader.h: Include location.h.
13777 (scanner_cursor): New decl.
13778 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
13780 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
13782 (STEP): Remove. No longer needed, now that adjust_location does
13783 the work. All uses removed.
13784 (scanner_cursor): New var.
13785 (adjust_location): Renamed from extend_location. It now sets
13786 *loc and adjusts the scanner cursor. All uses changed.
13787 Don't bother testing for CR.
13788 (handle_syncline): Remove location arg; now updates scanner cursor.
13789 All callers changed.
13790 (unexpected_end_of_file): Now accepts start boundary of token or
13791 comment, not location. All callers changed. Update scanner cursor,
13793 (SC_AFTER_IDENTIFIER): New state.
13794 (context_state): Renamed from c_context. All uses changed.
13795 (id_loc, code_start, token_start): New local vars.
13796 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
13797 processing of Yacc white space and equivalents here.
13798 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
13799 instead of returning ID immediately, since we need to search for
13800 a subsequent colon.
13801 (<INITIAL>"'", "\""): Save token_start.
13802 (<INITIAL>"%{", "{", "%%"): Save code_start.
13803 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
13804 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
13805 BEGIN context_state at end, not INITIAL.
13806 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
13807 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
13808 Return correct token start.
13809 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
13810 the start of a character, string or multiline comment is found.
13811 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
13812 Reduction): Adjust reported locations to match the more-precise
13813 results now expected.
13814 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
13815 * tests/reduce.at (Useless Rules, Reduced Automaton,
13816 Underivable Rules): Likewise.
13817 * tests/regression.at (Invalid inputs): No longer `expecting ";"
13818 or "|"' now that so many other tokens are allowed by the new grammar.
13820 * src/complain.h (current_file): Remove duplicate decl;
13821 current_file is now owned by files.h.
13822 * src/complain.c, src/scan-gram.l: Include files.h.
13824 2002-12-06 Paul Eggert <eggert@twinsun.com>
13826 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
13827 promotes to int; it might be unsigned int.
13828 * data/yacc.c (yy_reduce_print): Likewise.
13830 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
13831 be #defined in the prologue, not in the Bison declarations.
13832 This fixes Debian Bug 102878, reported by Shaul Karl.
13834 2002-12-02 Paul Eggert <eggert@twinsun.com>
13836 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
13837 * lib/strtoul.c: New file, from gnulib.
13838 This fixes a porting bug reported by Peter Klein in
13839 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13841 2002-11-30 Paul Eggert <eggert@twinsun.com>
13843 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13844 and put only a forward declaration in the prologue. This is for
13845 consistency with the other scanner helper functions.
13847 Type clashes now generate warnings, not errors, since it
13848 appears that POSIX may allow some grammars with type clashes.
13849 * src/reader.c (grammar_current_rule_check): Warn about
13850 type clashes instead of complaining.
13851 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13853 Add Yacc library, since POSIX requires it.
13854 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13855 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13856 * lib/main.c, lib/yyerror.c: New files.
13858 gram_error can be static; it need not be extern.
13859 * src/reader.h (gram_error): Remove decl.
13860 * src/parse-gram.y (gram_error): Now static. Add static decl.
13861 (print_token_value): Omit parameter names from forward decl,
13864 2002-11-29 Paul Eggert <eggert@twinsun.com>
13866 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13867 be declared before being used. E.g., one should typically
13868 declare them in the prologue. Use GNU coding style in examples.
13869 Put "const" consistently after the type it modifies. Mention
13870 that C99 supports "inline". Mention that yyerror traditionally
13873 %parse-param and %lex-param now take just one argument, the
13874 declaration; the argument name is deduced from the declaration.
13876 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13877 Reporting, Table of Symbols): Document this.
13878 * src/parse-gram.y (add_param): New function.
13880 (declaration): Implement new rule for %parse-param and %lex-param.
13881 * src/scan-gram.l: "," now elicits a warning, rather than being
13882 a token; this is more compatible with byacc.
13883 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13885 2002-11-27 Paul Eggert <eggert@twinsun.com>
13887 Rename identifiers to avoid real and potential collisions.
13889 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13890 to avoid collision with lex macro described by Bruce Lilly in
13891 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13892 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13893 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13894 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13896 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13897 The name "yycontrol" violates the name space rules, and this stuff
13898 wasn't being used anyway.
13899 (input): Remove action; this stuff wasn't being used.
13900 (gram_error): Rename local variable yylloc -> loc.
13901 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13902 (YY_DECL): Don't use "yy" at start of local variables.
13903 All uses changed, e.g., yylloc -> loc.
13904 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
13905 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
13906 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
13907 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
13909 * src/parse-gram.y (gram_error): loc is now const *.
13910 * src/reader.h (gram_error): Likewise.
13912 2002-11-24 Paul Eggert <eggert@twinsun.com>
13916 * tests/actions.at (Actions after errors): Use an output format
13917 more similar to that of the Printers and Destructors test.
13918 Test the position of the ';' token too.
13919 (Printers and Destructors): Likewise.
13920 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13921 unnecessarily alarming people when the test fails.
13923 * data/yacc.c (yyerrlab1): Move this label down, so that the
13924 parser does not discard the lookahead token if the user code
13925 invokes YYERROR. This change is required for POSIX conformance.
13927 * lib/error.c: Sync with gnulib.
13929 2002-11-22 Paul Eggert <eggert@twinsun.com>
13931 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
13932 * lib/mbswidth.c, lib/mbswidth.h: Likewise.

13935 2002-11-20 Paul Eggert <eggert@twinsun.com>
13937 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13939 2002-11-20 Paul Eggert <eggert@twinsun.com>
13941 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13942 should use `if (! x) abort ();' rather than `assert (x);', and
13943 anyway it's one less thing to worry about configuring.
13945 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13946 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13947 and replace all instances of assert with abort.
13948 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.

13976 rather than assert.
13977 * src/tables.c (tables_generate): Likewise.
13979 * src/struniq.c (struniq_assert): Now returns void, and aborts
13980 if the assertion is false.
13981 (struniq_assert_p): Remove.
13982 * src/struniq.h: Likewise.
13984 2002-11-18 Paul Eggert <eggert@twinsun.com>
13986 * data/glr.c (yygetLRActions): Replace `yyindex' with
13987 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
13988 This fixes the regression with Sun ONE Studio 7 cc that I reported in
13989 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
13991 2002-11-18 Akim Demaille <akim@epita.fr>
13993 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
13995 From Tim Van Holder.
13997 2002-11-17 Paul Eggert <eggert@twinsun.com>
13999 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
14000 to "SyntaxError" for consistency with my 2002-11-15 change.
14002 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
14003 not define to {}, since this breaks the common use of `YYDPRINTF
14004 ((...));' if a single statement is desired (e.g. before `else').
14005 Work around GCC warnings by surrounding corresponding calls with
14007 (yyhasResolvedValue): Remove unused function.
14008 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
14010 (yyreportSyntaxError): Renamed from yyreportParseError.
14011 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
14013 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
14014 extern when possible. Remove unused initializations.
14016 2002-11-16 Akim Demaille <akim@epita.fr>
14018 Augment the similarity between GLR and LALR traces.
14020 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
14021 (YY_REDUCE_PRINT): New.
14022 (yyparse): Use them.
14023 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
14025 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
14026 state reached after the reduction/recovery, since...
14027 (yyparse, yyprocessOneStack): Report the state we are entering in.
14029 2002-11-16 Akim Demaille <akim@epita.fr>
14031 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
14032 Add support for --trace=skeleton.
14033 * src/scan-skel.l: %option debug.
14034 Scan strings of non-@ or \n instead of character by character.
14035 (scan_skel): Handle trace_skeleton.
14037 (@output_parser_name@, @output_header_name@): ``Restore'' their
14038 support (used to be M4 macros).
14039 * data/yacc.c: Quote larger chunks, a la glr.c.
14040 * data/lalr1.cc: Likewise.
14041 The header guards are no longer available, so use some other
14042 string than `YYLSP_NEEDED'.
14044 2002-11-16 Akim Demaille <akim@epita.fr>
14046 Make the ``Printers and Destructors'' test more verbose, taking
14047 `yacc.c''s behavior as (possibly wrong) reference.
14049 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
14050 instead of fprint on stdout.
14051 Set and report the last_line of the symbols.
14052 Consistently display values and locations.
14054 2002-11-16 Paul Eggert <eggert@twinsun.com>
14056 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
14058 2002-11-15 Paul Eggert <eggert@twinsun.com>
14060 * tests/actions.at (Actions after errors): New test case.
14062 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
14063 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
14064 tests/action.at, tests/calc.at, tests/conflicts.at,
14065 tests/cxx-type.at, tests/regression.at:
14066 "parse error" -> "syntax error" for POSIX compatibility.
14067 "parsing stack overflow..." -> "parser stack overflow" so
14068 that code matches Bison documentation.
14070 2002-11-15 Akim Demaille <akim@epita.fr>
14072 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
14073 take two BRACED_CODE, not two string_content.
14074 Free the scanner's obstack when we are done.
14075 (code_content): New.
14076 * tests/calc.at: Adjust.
14077 * doc/bison.texinfo: Adjust.
14078 Also, make sure to include the `,' for these declarations.
14080 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
14082 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
14083 definition; avoids potential autoreconf problems.
14085 2002-11-15 Akim Demaille <akim@epita.fr>
14087 Always check the value returned by yyparse.
14089 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
14090 returned by yyparse.
14091 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
14093 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
14094 returned by yyparse.
14096 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14098 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
14101 2002-11-14 Paul Eggert <eggert@twinsun.com>
14103 * src/output.c (output_skeleton): Call xfopen instead of
14104 duplicating xfopen's body.
14106 Fix bugs reported by Nelson H. F. Beebe in
14107 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
14109 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
14110 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
14111 Group compiler. Instead, use "$CC -E bar.c". Include the .h
14112 file twice in the grammar, as an extra check.
14114 * tests/input.at (Torturing the Scanner): Surround the
14115 backslash-newline tests with "#if 0", to make it less likely that
14116 we'll run into compiler bugs. Bring back solitary \ inside
14117 comment, but add a closing comment to work around HP C bug. Don't
14118 test backslash-newline in C character constant.
14120 2002-11-14 Akim Demaille <akim@epita.fr>
14122 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
14123 status of the compiler.
14124 Calling `exit 1' is no longer needed.
14125 Reported by Nelson H. F. Beebe.
14127 2002-11-14 Akim Demaille <akim@epita.fr>
14129 * tests/atlocal.in (CPPFLAGS): We have config.h.
14130 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
14132 * tests/actions.at, tests/calc.at, tests/conflicts.at,
14133 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
14134 * tests/regression.at, tests/torture.at: Use them for all the
14135 grammars that are to be compiled.
14136 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
14137 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
14138 * doc/bison.texinfo (GLR Parsers): Document `inline'.
14140 2002-11-14 Akim Demaille <akim@epita.fr>
14142 * doc/bison.texinfo: Various formatting changes (alignments in
14143 samples, additional @group/@end group, GCS in samples.
14144 Use @deffn instead of simple @table to define the directives,
14145 macros, variables etc.
14147 2002-11-13 Paul Eggert <eggert@twinsun.com>
14149 Fix some bugs reported by Albert Chin-A-Young in
14150 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
14152 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
14153 -o c"; the HP C compiler chatters during compilation.
14154 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
14155 * tests/headers.at (export YYLTYPE): Likewise.
14157 * tests/input.at (Torturing the Scanner): Remove lines containing
14158 solitary backslashes, as they tickle a bug in the HP C compiler.
14160 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
14161 comments, since they're not portable. Use GNU coding style.
14163 2002-11-13 Akim Demaille <akim@epita.fr>
14165 * data/yacc.c: Leave bigger chunks of quoted text.
14166 (YYDSYMPRINTF): New.
14167 Use it to report symbol activities.
14168 * data/glr.c (YYDSYMPRINTF): New.
14171 2002-11-12 Paul Eggert <eggert@twinsun.com>
14175 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
14176 (yyglrReduce): Return yyok, not 0.
14177 This should avoid the enumerated-type warnings reported
14178 by Nelson H. F. Beebe in
14179 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
14181 * lib/bbitset.h (BITSET_INLINE): Remove.
14182 * lib/bitset.h [! BITSET_INLINE]: Remove.
14183 (bitset_set, bitset_reset, bitset_test): Rename local vars
14184 to avoid shadowing warnings by GCC.
14186 * data/glr.c (inline): Remove #define. It's the user's
14187 responsibility to #define it away, just like 'const'.
14188 This fixes one of the bugs reported by Nelson H. F. Beebe in
14189 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
14191 * Makefile.maint (po-check): Scan .l and .y files instead of the
14192 .c and the .h files that they generate. This fixes the bug
14193 reported by Tim Van Holder in:
14194 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
14195 Look for N_ as well as for _. Try to avoid matching #define for
14197 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
14198 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
14199 * src/scan-gram.l: Revamp regular expressions so that " and '
14200 do not confuse xgettext.
14202 * src/struniq.h (struniq_new): Do not declare the return type
14203 to be 'const'; this violates the C standard.
14204 * src/struniq.c (struniq_new): Likewise.
14206 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
14208 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
14209 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
14212 2002-11-12 Akim Demaille <akim@epita.fr>
14214 * Makefile.maint: Sync with Autoconf:
14215 (local_updates): New.
14217 2002-11-12 Akim Demaille <akim@epita.fr>
14219 * po/POTFILES.in (src/lalr.c, src/state.c): Remove

14231 2002-11-12 Akim Demaille <akim@epita.fr>
14233 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
14234 Use it to test the GLR parser.
14236 2002-11-12 Akim Demaille <akim@epita.fr>
14238 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
14240 * data/glr.c (yystos): New.
14241 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
14242 (YYDSYMPRINT): New.
14243 (yyval): Don't define it, it is handled via M4.
14244 (yyrecoverParseError): Free verbosely the discarded symbols.
14245 * data/yacc.c (yysymprint): Remove, rather...
14246 (b4_yysymprint_generate): invoke.
14247 * data/c.m4 (b4_yysymprint_generate): New.
14248 Accept pointers as arguments, as opposed to the version from
14250 (b4_yydestruct_generate): Likewise.
14251 * tests/cations.at (Printers and Destructors): Use Bison directives
14252 instead of CPP macros.
14253 Don't rely on internal details.
14255 2002-11-12 Akim Demaille <akim@epita.fr>
14257 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
14258 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
14259 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
14260 it against YYEMPTY and so forth), work on yytoken (i.e., set
14261 it to YYEMPTY etc.).
14262 (yydestruct): Replace with a b4_yydestruct_generate invocation.
14263 (b4_symbol_actions): Remove.
14264 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
14265 for 0, end-of-input.
14267 2002-11-12 Akim Demaille <akim@epita.fr>
14269 * doc/bison.texinfo (Destructor Decl): New.
14271 2002-11-12 Akim Demaille <akim@epita.fr>
14273 * src/tables.c (tables_generate): Use free for pointers that
14274 cannot be NULL, not XFREE.
14275 (pack_vector): Use assert, not fatal, for bound violations.
14276 * src/state.c (state_new): Likewise.
14277 * src/reader.c (reader): Likewise.
14278 * src/lalr.c (set_goto_map): Likewise.
14279 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
14282 2002-11-12 Akim Demaille <akim@epita.fr>
14284 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
14286 * src/scan-gram.l (last_string): Is global to the file, not to
14288 * src/parse-gram.y (input): Don't append the epilogue here,
14289 (epilogue.opt): do it here, and free the scanner's obstack.
14290 * src/reader.c (epilogue_set): Rename as...
14291 (epilogue_augment): this.
14292 * data/c.m4 (b4_epilogue): Defaults to empty.

14350 2002-11-11 Paul Eggert <eggert@twinsun.com>
14352 Revamp to fix many (but not all) of the C- and M4-related quoting
14353 problems. Among other things, this fixes the Bison bug reported
14354 by Jan Hubicka when processing the Bash grammar; see:
14355 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
14357 Use new @ escapes consistently. Represent brackets with @{ and @}
14358 rather than @<:@ and @:>@, since this works a bit better with dumb
14359 editors like vi. Represent @ with @@, since @ is now consistently
14360 an escape. Use @oline@ and @ofile@ rather than __oline__ and
14361 __ofile__, to avoid unexpected expansions. Similarly, use @output
14362 rather than #output.
14364 * data/c.m4 (b4_copyright): Omit file name from comment, since
14365 the file name could contain "*/".
14366 (b4_synclines_flag): Don't quote the 2nd argument; it should already
14367 be quoted. All uses changed.
14369 * data/glr.c: Use new @ escapes consistently.
14370 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
14371 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
14372 Remove, since they couldn't handle arbitrary characters in file
14374 * data/lalr1.cc: Likewise.
14375 * data/yacc.c: Likewise.
14377 * src/files.c (output_infix): Remove; all uses removed.
14378 * src/files.h: Likewise.
14380 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
14381 mishandled funny characters in file names, and anyway it isn't
14383 * data/yacc.c: Likewise.
14384 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
14386 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
14387 * data/yacc.c: Likewise.
14389 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
14391 (muscle_init): Quote filename as a C string.
14392 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
14393 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
14394 * src/output.c (escaped_file_name_output): New function.
14395 (prepare_symbols): Quote tokens for M4.
14396 (prepare): Don't insert output_infix, output_prefix,
14397 output_parser_name, output_header_name; this is now down by scan-skel.
14398 Insert skeleton as a C string.
14400 * src/output.c (user_actions_output, symbol_destructors_output,
14401 symbol_printers_output): Quote filenames for C and M4.
14402 * src/reader.c (prologue_augment, epilogue_set): Likewise.
14404 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
14405 escapes other than \\ and \'; this simplifies the code.
14406 (<SC_STRING>): Likewise, for \\ and \".
14407 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
14408 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
14409 Use new escapes @{ and @} for [ and ].
14411 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
14412 them with auto vars.
14413 Switch to new escape scheme, where @ is the escape character uniformly.
14414 Abort if a stray escape character is found. Avoid unbounded input
14415 buffer when parsing non-escaped text.
14417 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
14418 __oline__, #output, $@, and @{ do not have unintended meanings.
14420 2002-11-09 Paul Eggert <eggert@twinsun.com>
14422 Fix the test failure due to GCC warnings described in
14423 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
14424 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
14425 evaluate to 0 if it's impossible for NINF to be in the respective
14427 (yygetLRActions, yyrecoverParseError): Use them.
14429 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
14430 counted in the token inserted at end of file. Now takes
14431 location_t *, not location_t, so that the location can be
14432 adjusted. All uses changed.
14434 * tests/regression.at (Invalid inputs): Adjust wording in
14435 diagnostic to match the new behavior.
14437 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
14438 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
14439 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
14440 abort ();'. This reduces the runtime of the "Many lookaheads"
14441 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
14444 2002-11-07 Paul Eggert <eggert@twinsun.com>
14446 * src/parse-gram.y (CHARACTER): Remove unused token.
14449 * src/scan-gram.l: Remove stack option. We no longer use the
14450 stack, since the stack was never deeper than 1; instead, use the
14451 new auto var c_context to record the stacked value.
14453 Remove nounput option. At an unexpected end of file, we now unput
14454 the minimal input necessary to end cleanly; this simplifies the
14457 Avoid unbounded token sizes where this is easy.
14459 (unexpected_end_of_file): New function.
14460 Use it to systematize the error message on unexpected EOF.
14461 (last-string): Now auto, not static.

14464 (percent_percent_count): Move decl to just before use.
14465 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
14466 not the (never otherwised-used) CHARACTER.
14468 2002-11-07 Akim Demaille <akim@epita.fr>
14470 Let yyerror always receive the msg as last argument, so that
14471 yyerror can be variadic.
14473 * data/yacc.c (b4_yyerror_args): New.
14474 Use it when calling yyerror.
14475 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

14481 2002-11-06 Akim Demaille <akim@epita.fr>
14483 #line should have quoted strings.
14484 Ideally, this should be done by m4_quotearg.
14486 * src/scan-skel.l: Include quotearg.h.
14488 * src/output.c (symbol_printers_output)
14489 (symbol_destructors_output): Quote the file name.

14504 * src/output.c (user_actions_output): Likewise.
14505 (prepare): Define 'b4_synclines_flag'.
14506 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
14508 2002-11-06 Akim Demaille <akim@epita.fr>
14510 * src/main.c (main): Free `infile'.

14513 * src/output.c (user_actions_output, symbol_destructors_output)
14514 (symbol_printers_output): Use the location's file name, not

14518 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14520 * src/tables.c (matching_state): Don't allow states to match if
14521 either has GLR conflict entries.
14523 2002-11-05 Paul Eggert <eggert@twinsun.com>
14525 * src/scan-gram.l: Use more accurate diagnostics, e.g.
14526 "integer out of range" rather than "invalid value".
14527 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
14530 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
14531 Also, remove one static variable in the scanner.
14533 * src/scan-gram.l (braces_level): Now auto, not static.
14534 Initialize to zero if the compiler is being picky.
14535 (INITIAL): Clear braces_level instead of incrementing it.
14536 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
14537 as POSIX 1003.1-2001 requires.
14538 * src/system.h (IF_LINT): New macro, taken from coreutils.
14539 * configure.ac: Define "lint" if --enable-gcc-warnings.
14541 2002-11-05 Akim Demaille <akim@epita.fr>
14543 * src/scan-gram.l: When it starts with `%', complain about the
14544 whole directive, not just that `invalid character: %'.
14546 2002-11-04 Akim Demaille <akim@epita.fr>
14548 * Makefile.maint: Update from Autoconf.
14549 (update, cvs-update, po-update, do-po-update): New.
14551 2002-11-04 Akim Demaille <akim@epita.fr>
14553 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
14555 Have yyerror `use' its arguments.
14556 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
14557 returns true when location & yacc & pure & parse-param.
14558 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
14560 2002-11-04 Akim Demaille <akim@epita.fr>
14562 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
14564 * src/scan-gram.l: Use [\'] instead of ['] to pacify
14567 Use quote, not quote_n since LOCATION_PRINT no longer uses the
14570 2002-11-03 Paul Eggert <eggert@twinsun.com>
14572 * src/reader.c (get_merge_function, grammar_current_rule_check):
14573 Use consistent diagnostics for reporting type name clashes.
14574 Quote the types with <>, for consistency with Yacc.
14575 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
14577 2002-11-03 Akim Demaille <akim@epita.fr>
14579 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
14581 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
14582 (b4_parse_param): Remove.
14583 Use b4_identification.
14584 Propagate b4_pure_args where needed to pass them to yyerror.
14585 * data/glr.m4 (b4_parse_param): Remove.
14586 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

14589 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
14590 b4_user_formals and b4_user_args.
14591 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
14592 (yyreportAmbiguity): When using a pure parser, also need
14593 the location, and the parse-params.
14595 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
14596 When using a pure parser, also need the parse-params.
14598 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
14599 (%pure-parser + %parse-param) LALR and GLR parsers.
14600 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
14601 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
14602 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
14603 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

14606 * doc/bison.texinfo: Untabify the whole file.
14607 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
14608 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
14609 (Error Reporting): Adjust to these new directives.
14610 Document %error-verbose, deprecate YYERROR_VERBOSE.
14612 2002-11-03 Akim Demaille <akim@epita.fr>
14614 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
14615 AT_CHECK_CALC_GLR invocations to use % directives, instead of
14616 command line options.
14617 * tests/cxx-type.at: Formatting changes.
14619 2002-11-03 Paul Eggert <eggert@twinsun.com>
14621 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
14622 to count columns correctly, and to check for invalid inputs.
14624 Use mbsnwidth to count columns correctly. Account for tabs, too.
14625 Include mbswidth.h.
14626 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
14627 (extend_location): New function.
14628 (YY_LINES): Remove.
14630 Handle CRLF in C code rather than in Lex code.
14631 (YY_INPUT): New macro.
14632 (no_cr_read): New function.
14634 Scan UCNs, even though we don't fully handle them yet.

14637 Handle backslash-newline correctly in C code.
14638 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
14639 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
14641 (tag, splice): New EREs. Do not allow NUL or newline in tags.
14642 Use {splice} wherever C allows backslash-newline.
14643 YY_STEP after space, newline, vertical-tab.
14644 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
14646 (letter, id): Don't assume ASCII; e.g., spell out a-z.
14648 ({int}, handle_action_dollar, handle_action_at): Check for integer
14651 (YY_STEP): Omit trailing semicolon, so that it's more like C.
14653 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
14654 as well as \000. Check for UCHAR_MAX, not 255.
14655 Allow \x with an arbitrary positive number of digits, as in C.
14656 Check for overflow here.
14657 Allow \? and UCNs, for compatibility with C.
14659 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
14660 with quote slot used by complain_at.
14662 * tests/input.at: Add tests for backslash-newline, m4 quotes
14663 in symbols, long literals, and funny escapes in strings.
14665 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
14666 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
14667 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
14668 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
14669 * m4/mbswidth.m4: New file, from GNU coreutils.
14671 * doc/bison.texinfo (Grammar Outline): Document // comments.
14672 (Symbols): Document that trigraphs have no special meaning in Bison,
14673 nor is backslash-newline allowed.
14674 (Actions): Document that trigraphs have no special meaning.

14679 2002-11-02 Paul Eggert <eggert@twinsun.com>
14681 * src/reader.c: Don't include quote.h; not needed.
14682 (get_merge_function): Reword warning to be consistent with
14683 type clash diagnostic in grammar_current_rule_check.
14685 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
14686 bug in trigraph handling.
14688 * src/output.c (prepare_symbols): When printing token names,
14689 escape "[" as "@<:@" and likewise for "]".
14691 * src/system.h (errno): Remove declaration, as we are now
14692 assuming C89 or better, and C89 guarantees errno.
14694 2002-10-30 Paul Eggert <eggert@twinsun.com>
14696 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
14697 Check for close failures.
14698 * src/files.h (xfclose): Return void, not int, since it always
14700 * src/files.c (xfclose): Likewise. Report I/O error if ferror
14702 * src/output.c (output_skeleton): Use xfclose rather than fclose
14703 and ferror. xfclose now checks ferror.
14705 * data/glr.c (YYLEFTMOST_STATE): Remove.
14706 (yyreportTree): Use a stack-based leftmost state. This avoids
14707 our continuing battles with bogus warnings about initializers.
14709 2002-10-30 Akim Demaille <akim@epita.fr>
14711 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

14724 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
14725 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
14726 we use malloc. Don't assume 'A' through 'Z' are contiguous.
14727 Don't assume strdup exists; POSIX says its an XSI extension.
14728 Check for buffer overflow on input.
14730 2002-10-24 Akim Demaille <akim@epita.fr>
14732 * src/output.c (output_skeleton): Don't disable M4sugar comments
14733 too soon: it results in comments being expanded.
14734 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
14737 2002-10-24 Akim Demaille <akim@epita.fr>
14739 * data/yacc.c (m4_int_type): New.
14740 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
14741 char' as only yacc.c wants K&R portability.
14742 * data/glr.c (yysigned_char): Remove.
14743 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
14744 Reported by Quoc Peyrot.
14746 2002-10-23 Paul Eggert <eggert@twinsun.com>
14748 * src/main.c (main): With --trace=time, report times even if a
14749 non-fatal error occurs. Formerly, the times were reported in some
14750 such cases but not in others.
14751 * src/reader.c (reader): Just return if a complaint has been issued,
14752 instead of exiting, so that 'main' can report times.
14754 2002-10-22 Akim Demaille <akim@epita.fr>
14756 * src/system.h: Include sys/types.
14757 Reported by Bert Deknuydt.
14759 2002-10-23 Paul Eggert <eggert@twinsun.com>
14761 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
14762 Suggested by Art Haas.
14764 2002-10-22 Paul Eggert <eggert@twinsun.com>
14766 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14767 decl; not needed any more.
14768 * src/main.c (main): Use return to exit, undoing yesterday's change.
14769 The last OS that we could find where this wouldn't work is
14770 SunOS 3.5, and that's too old to worry about now.
14772 * data/glr.c (struct yyltype): Define members even when not
14773 doing locations. This is more consistent with yacc.c, and it
14774 works around the following bug reports:
14775 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
14776 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
14778 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
14779 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14780 "Algol" instead of "ALGOL". Give a bit more history about BNF.
14782 2002-10-22 Akim Demaille <akim@epita.fr>
14784 * data/README: New.
14786 2002-10-21 Paul Eggert <eggert@twinsun.com>
14788 Be consistent about 'bool'; the old code used an enum in one
14789 module and an int in another, and this violates the C standard.
14790 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14791 * configure.ac (AC_HEADER_STDBOOL): Add.
14792 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14793 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14794 * src/symtab.c (hash_compare_symbol_t): Likewise.
14795 * src/system.h (bool, false, true): Use a definition consistent
14796 with ../lib/hash.c. All uses changed.
14798 * src/complain.c (warning_issued): Renamed from warn_message_count,
14799 so that we needn't worry about integer overflow (!).
14800 Now of type bool. All uses changed.
14801 (complaint_issued): Renamed from complain_message_count; likewise.
14803 * src/main.c (main): Use exit to exit with failure.
14805 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
14806 rather than 1 and 0.
14807 * src/main.c (main): Likewise.
14808 * src/getargs.c (getargs): Likewise.
14809 * src/reader.c (reader): Likewise.
14811 * src/getarg.c (getargs): Remove duplicate code for
14812 "Try `bison --help'".
14814 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
14815 What was that "2" for?
14817 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14818 * src/getargs.c (usage): Likewise.
14820 * src/getargs.c (getargs): When there are too few operands, report
14821 the last one. When there are too many, report the first extra
14822 one. This is how diffutils does it.
14824 2002-10-20 Paul Eggert <eggert@twinsun.com>
14826 Remove K&R vestiges.
14827 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
14828 * src/complain.c (VA_START): Remove. Assume prototypes.
14829 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
14830 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
14831 fatal): Assume prototypes.
14832 * src/complain.h: Assume prototypes.
14833 * src/system.h (PARAMS): Remove.
14834 Include <limits.h> unconditionally, since it's guaranteeed even
14835 for a freestanding C89 compiler.
14836 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
14837 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
14839 2002-10-20 Akim Demaille <akim@epita.fr>
14841 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
14842 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
14843 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
14844 (yyresolveStates, yyresolveAction, yyresolveStack)
14845 (yyprocessOneStack): Use them.
14846 (yy_reduce_print): New.
14847 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
14849 2002-10-20 Akim Demaille <akim@epita.fr>
14851 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14852 arguments and output `void'.
14853 (b4_c_function): Rename as...

14855 (b4_c_function_decl, b4_c_ansi_function_def)
14856 (b4_c_ansi_function_decl): New.
14857 Change the interpretation of the arguments: before `int, foo', now
14859 * data/yacc.c (yyparse): Prototype and define thanks to these.
14860 Adjust b4_c_function_def uses.
14861 * data/glr.c (yyparse): Likewise, but ANSI only.
14863 2002-10-20 Akim Demaille <akim@epita.fr>
14865 * src/output.c (prepare): Move the definition of `tokens_number',
14866 `nterms_number', `undef_token_number', `user_token_number_max'
14868 (prepare_tokens): Here.

14873 (prepare): Move the definition of `last', `final_state_number',
14874 `states_number' to...
14875 (prepare_states): here.
14876 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
14878 2002-10-20 Akim Demaille <akim@epita.fr>

14898 2002-10-19 Paul Eggert <eggert@twinsun.com>
14900 Do not create a temporary file, as that involves security and
14901 cleanup headaches. Instead, use a pair of pipes.
14902 Derived from a suggestion by Florian Krohm.
14903 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14904 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
14905 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
14906 (BISON_PREREQ_SUBPIPE): Add.
14907 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
14908 Add subpipe.h, subpipe.c.

14913 (scan_skel): New decl.
14914 (output_skeleton): Use pipe rather than temporary file for m4 input.

14916 Check for pipe I/O error.
14917 * src/scan-skel.l (readpipe): Remove decl.
14918 (scan_skel): New function, to be used in place of m4_invoke.
14919 Read from stream rather than file.
14921 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14922 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14923 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14924 this generates a more-accurate value anyway.
14926 * lib/timevar.c (timervar_accumulate): Rename locals to
14927 avoid confusion with similarly-named more-global.
14928 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14930 * src/output.c (prepare): Use xstrdup to convert char const *
14931 to char *, to avoid GCC warning.
14933 2002-10-19 Akim Demaille <akim@epita.fr>
14935 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14936 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14937 Use them to have `calc.y' ready for %pure-parser.
14938 * data/yacc.c (YYLEX): Pass a yylex return type to
14939 b4_c_function_call.
14941 2002-10-19 Akim Demaille <akim@epita.fr>
14943 Prototype support of %lex-param and %parse-param.
14945 * src/parse-gram.y: Add the definition of the %lex-param and
14946 %parse-param tokens, plus their rules.
14947 Drop the `_' version of %glr-parser.
14949 * src/scan-gram.l (INITIAL): Scan them.
14950 * src/muscle_tab.c: Comment changes.
14951 (muscle_insert, muscle_find): Rename `pair' as `probe'.
14952 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
14953 (muscle_entry_s): The `value' member is no longer const.
14954 Adjust all dependencies.
14955 * src/muscle_tab.c (muscle_init): Adjust: use
14956 MUSCLE_INSERT_STRING.
14957 Initialize the obstack earlier.
14958 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14959 (muscle_pair_list_grow): New.
14960 * data/c.m4 (b4_c_function_call, b4_c_args): New.
14961 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
14962 * tests/calc.at: Use %locations, not --locations.
14963 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14965 2002-10-19 Akim Demaille <akim@epita.fr>
14967 * src/getargs.c (usage): Take status as argument and exit
14969 Report the traditional `Try ... --help' message when status != 0.
14970 (usage, version): Don't take a FILE * as arg, it is pointless.
14971 (getargs): When there is an incorrect number of arguments, make it
14972 an error, and report it GNUlically thanks to `usage ()'.
14974 2002-10-18 Paul Eggert <eggert@twinsun.com>
14976 * data/glr.c (yyreportParseError): Don't assume that sprintf
14977 yields the length of the printed string, as this is not true
14978 on SunOS 4.1.4. Reported by Peter Klein.
14980 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14981 * tests/conflicts.at (%nonassoc and eof): Likewise.
14982 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14984 2002-10-17 Akim Demaille <akim@epita.fr>
14986 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14987 * src/getargs.c (trace_types, trace_args): Adjust.
14988 * src/reader.c (grammar_current_rule_prec_set)
14989 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
14990 Standardize error messages.
14991 And s/@prec/%prec/!
14992 (reader): Use trace_flag to enable scanner/parser debugging,
14993 instead of an adhoc scheme.
14994 * src/scan-gram.l: Remove trailing debugging code.
14996 2002-10-16 Paul Eggert <eggert@twinsun.com>
14998 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
15001 * NEWS: Officially drop support for building Bison with K&R C,
15002 since it didn't work anyway and it's not worth worrying about.
15003 * Makefile.maint (wget_files): Remove ansi2knr.c.
15004 (ansi2knr.c-url_prefix): Remove.
15005 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
15006 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15007 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15009 2002-10-15 Paul Eggert <eggert@twinsun.com>
15011 Stop using the "enum_" trick for K&R-style function definitions;
15012 it confused me, and I was the author! Instead, assume that people
15013 who want to use K&R C compilers (when using these modules in GCC,
15014 perhaps?) will run ansi2knr.
15016 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
15017 All uses of "enum_" changed to "enum ".
15018 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15019 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15021 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

15029 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
15030 Use function prototypes; this removes the need for declaring
15031 static functions simply to provide their prototypes.
15032 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

15098 2002-10-14 Akim Demaille <akim@epita.fr>
15100 * src/tables.c (table_ninf_remap): base -> tab.
15101 Reported by Matt Rosing.
15103 2002-10-14 Paul Eggert <eggert@twinsun.com>
15105 * tests/action.at, tests/calc.at, tests/conflicts.at,
15106 tests/cxx-type.at, tests/headers.at, tests/input.at,
15107 tests/regression.at, tests/synclines.at, tests/torture.at:
15108 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
15109 so that the tests still work even if POSIXLY_CORRECT is set.
15110 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
15112 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
15113 for portability to K&R hosts. Fix typo: signed char is guaranteed
15114 only to 127, not to 128.
15115 * data/glr.c (yysigned_char): New type.
15116 * data/yacc.c (yysigned_char): Likewise.
15117 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
15119 2002-10-13 Paul Eggert <eggert@twinsun.com>
15121 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
15122 true due to limited range of data type" warning from GCC.
15124 * data/c.m4 (b4_token_defines): Protect against double-inclusion
15125 by wrapping enum yytokentype's definition inside #ifndef
15126 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
15128 2002-10-13 Akim Demaille <akim@epita.fr>
15130 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
15131 Un yy- yyrhs to avoid the name clash with the global YYRHS.
15133 2002-10-13 Akim Demaille <akim@epita.fr>
15135 * Makefile.maint: Update from Autoconf 2.54.
15136 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
15138 2002-10-13 Akim Demaille <akim@epita.fr>
15140 * src/print.c (print_state): Separate the list of solved conflicts
15141 from the other items.
15142 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
15144 2002-10-13 Akim Demaille <akim@epita.fr>
15146 Let nondeterministic skeletons be usable with deterministic
15149 With the patch, GAWK compiled by GCC without -O2 passes its test
15150 suite using a GLR parser driven by LALR tables. It fails with -O2
15151 because `struct stat' gives two different answers on my machine:
15152 88 (definition of an auto var) and later 96 (memset on this var).
15153 Hence the stack is badly corrumpted. The headers inclusion is to
15154 blame: if I move the awk.h inclusion before GLR's system header
15155 inclusion, the two struct stat have the same size.
15157 * src/tables.c (pack_table): Always create conflict_table.
15158 (token_actions): Always create conflict_list.
15159 * data/glr.c (YYFLAG): Remove, unused.
15161 2002-10-13 Akim Demaille <akim@epita.fr>
15163 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
15165 (VALGRIND, GXX): New.
15166 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
15167 * tests/bison.in: Run $PREBISON a pre-command.
15168 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
15169 (maintainer-check-g++): New.
15170 * Makefile.am (maintainer-check): New.
15172 2002-10-13 Akim Demaille <akim@epita.fr>
15174 * data/glr.c: Formatting changes.
15175 Tweak some trace messages to match yacc.c's.
15177 2002-10-13 Akim Demaille <akim@epita.fr>
15179 GLR parsers sometimes raise parse errors instead of performing the
15181 Reported by Charles-Henry de Boysson.
15183 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
15184 check the length of the traces when %glr.
15185 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
15187 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
15189 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
15190 (yyltype): Remove the yy prefix from the member names.
15191 (yytable): Complete its comment.
15192 (yygetLRActions): Map error action number from YYTABLE from
15194 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
15195 (which was a bug: it should have been YYTABEL_NINF, and yet it was
15196 not satisfying as we could compare an YYACTION computed from
15197 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
15198 only value for error actions.
15199 (yyreportParseError): In verbose parse error messages, don't issue
15200 `error' in the list of expected tokens.
15201 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
15202 next action to perform to match glr.c's decoding.
15203 (yytable): Complete its comment.
15205 2002-10-13 Paul Eggert <eggert@twinsun.com>
15207 Fix problem reported by Henrik Grubbstroem in
15208 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
15209 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
15210 because the Bison parser reads the second action before reducing
15212 * src/scan-gram.l (rule_length): New static var.
15213 Use it to keep track of the rule length in the scanner, since
15214 we can't expect the parser to be in lock-step sync with the scanner.
15215 (handle_action_dollar, handle_action_at): Use this var.
15216 * tests/actions.at (Exotic Dollars): Test for the problem.
15218 2002-10-12 Paul Eggert <eggert@twinsun.com>
15220 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
15221 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
15222 Include <sys/time.h> when checking for clock_t and struct tms.
15223 Use same include order as source.
15224 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
15225 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
15227 * lib/timevar.c: Update copyright date and clarify comments.
15228 (get_time) [IN_GCC]: Keep the GCC version for reference.
15230 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
15231 GCC version as of today, then merge Bison's changes.
15232 Change "GCC" to "Bison" in copyright notice. timevar.def's
15233 author is Akim, so change that too.
15235 * src/reader.c (grammar_current_rule_check):
15236 Don't worry about the default action if $$ is untyped.
15237 Prevents bogus warnings reported by Jim Gifford in
15238 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
15240 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
15241 * data/glr.c, data/lalr1.cc, data/yacc.c:
15242 Output token definitions before the first part of user declarations.
15243 Fixes compatibility problem reported by Jim Gifford for kbd in
15244 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
15246 2002-10-11 Paul Eggert <eggert@twinsun.com>
15248 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
15249 (yyparse): here. This undoes some of the 2002-07-25 change.
15250 Compatibility problem reported by Ralf S. Engelschall with
15251 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
15253 2002-10-11 Akim Demaille <akim@epita.fr>

15264 2002-10-10 Paul Eggert <eggert@twinsun.com>
15266 Portability fixes for bitsets; this also avoids several GCC
15269 * lib/abitset.c: Include <stddef.h>, for offsetof.
15270 * lib/lbitset.c: Likewise.
15272 * lib/abitset.c (abitset_bytes): Return a size that is aligned
15273 properly for vectors of objects. Do not assume that adding a
15274 header size to a multiple of a word size yields a value that is
15275 properly aligned for the whole union.
15276 * lib/bitsetv.c (bitsetv_alloc): Likewise.
15278 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
15279 unique names for structures.
15280 * lib/ebitset.c (ebitset_bytes): Likewise.
15281 * lib/lbitset.c (lbitset_bytes): Likewise.
15283 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
15284 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
15285 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,

15288 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
15289 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
15290 to improve the type-checking that GCC can do.
15291 * lib/bitset.c (bitset_op4_cmp): Likewise.
15292 * lib/bitset_stats.c (bitset_stats_count,
15293 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
15294 bitset_stats_copy, bitset_stats_disjoint_p,

15308 * lib/ebitset.h: Likewise.
15309 * lib/lbitset.h: Likewise.
15311 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
15312 All instances of parameters of type enum bitset_opts are now of
15313 type enum_bitset_opts, to conform to the C Standard, and similarly
15314 for enum_bitset_type.
15315 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15316 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15318 Do not use "struct bitset_struct" to mean different things in
15319 different modules. Not only is this confusing, it violates
15320 the C Standard, which requires that structure types in different
15321 modules must be compatible if one is to be passed to the other.
15322 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
15323 All instances of "struct bitset_struct *" replaced with "bitset".
15324 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
15325 (union bitset_union, struct abitset_struct, struct ebitset_struct,
15326 struct lbitset_struct, struct bitset_stats_struct): New types.
15327 All uses of struct bitset_struct changed to union bitset_union,
15329 * lib/abitset.c (struct abitset_struct, abitset,

15331 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
15332 struct bitset_struct): Remove.
15333 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
15334 bitset_struct): Remove.
15335 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
15338 Do not call a function of type T using a call that assumes the
15339 function is of a different type U. Standard C requires that a
15340 function must be called with a type that is compatible with its
15342 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
15344 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
15346 * lib/ebitset.c (PFV): Remove.
15347 * lib/lbitset.c (PFV): Likewise.

15357 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
15360 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
15362 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
15363 Use offsetof, for simplicity.
15365 2002-10-06 Paul Eggert <eggert@twinsun.com>
15367 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
15368 the same width as int. This reapplies a hunk of the 2002-08-12 patch
15369 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
15370 which was inadvertently undone by the 2002-09-30 patch.
15371 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
15372 the same width as int.
15374 2002-10-04 Paul Eggert <eggert@twinsun.com>
15378 * configure.ac (AC_INIT), NEWS: Increment version number.
15380 * doc/bison.texinfo: Minor spelling, grammar, and white space
15382 (Symbols): Mention that any negative value returned from yylex
15383 signifies end-of-input. Warn about negative chars. Mention
15384 the portable Standard C character set.
15386 The GNU coding standard says CFLAGS and YFLAGS are reserved
15387 for the installer to set.
15388 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
15389 * src/Makefile.am (AM_CFLAGS): Likewise.
15390 (AM_YFLAGS): Renamed from YFLAGS.
15392 Fix some MAX and MIN problems.

15394 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
15395 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
15396 * src/reader.c (reader): Use it.
15398 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
15399 POSIX 1003.1-2001 has removed fgrep.
15401 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

15746 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
15747 exit status as failure, not just exit status 1. Sun C exits
15748 with status 2 sometimes.

15918 parsers now contain `reduce 0' as default reduction.

15969 token_translations instead of `0'.
15970 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
15972 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
15973 for the time being: %locations ought to provide it to yyerror.

15977 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

15992 Handle the `- 1' part in rule numbers from/to item numbers.

17622 * data/bison.c++ (r1_): Likewise.
17623 * tests/regression.at (Web2c Actions): Adjust.
17625 2002-04-22 Akim Demaille <akim@epita.fr>
17627 * src/reader.c (token_translations_init): 256 is now the default
17628 value for the error token, i.e., it will be assigned another
17629 number if the user assigned 256 to one of her tokens.
17630 (reader): Don't force 256 to error.
17631 * doc/bison.texinfo (Symbols): Adjust.
17632 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
17633 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
17634 etc. instead of 10, 20, 30 (which was used to `jump' over error
17635 (256) and undefined (2)).
17637 2002-04-22 Akim Demaille <akim@epita.fr>
17639 Propagate more token_number_t.

17674 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
17675 full stderr, and strip it according to the bison options, instead
17676 of composing the error message from different bits.
17677 This makes it easier to check for several error messages.
17678 Adjust all the invocations.
17679 Add an invocation exercising the error token.
17680 Add an invocation demonstrating a stupid error message.
17681 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

17687 * src/gram.h, src/gram.c (error_token_number): Remove, use
17689 * src/reader.c (reader): Don't specify the user token number (2)

17692 * src/symtab.h: here.
17693 (state_t.number): Is a token_number_t.

17697 undeftoken remains being 2, it is its user token number which
17699 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
17700 `user_token_number_max'.
17701 Output `undef_token_number'.

17722 * src/gram.h (item_number_t): New, the type of item numbers in
17723 RITEM. Note that it must be able to code symbol numbers as
17724 positive number, and the negation of rule numbers as negative

17741 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
17742 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
17743 passes, but produces negative #line number, once fixed, GCC is
17744 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of

17944 2002-04-07 Akim Demaille <akim@epita.fr>
17946 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
17947 lacking `+ 1' to nrules, Bison reported as useless a token if it
17948 was used solely to set the precedence of the last rule...
17950 2002-04-07 Akim Demaille <akim@epita.fr>
17952 * data/bison.c++, data/bison.simple: Don't output the current file
17953 name in #line, to avoid useless diffs between two identical
17954 outputs under different names.
17956 2002-04-07 Akim Demaille <akim@epita.fr>
17958 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

17974 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
17975 RHS, instead of being an index in RITEMS.
17977 2002-04-04 Paul Eggert <eggert@twinsun.com>
17979 * doc/bison.texinfo: Update copyright date.
17980 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

18119 * src/reduce.c: Remove the `bitset_zero's following the
18120 `bitset_create's, as now it is performed by the latter.

18206 notice in each output file.
18208 2002-02-28 Akim Demaille <akim@epita.fr>
18210 * data/bison.c++: Copy the prologue of bison.simple to fetch
18211 useful M4 definitions, such as b4_header_guard.
18213 2002-02-25 Akim Demaille <akim@epita.fr>
18215 * src/getargs.c (version): Give the name of the authors, and use a

18244 2002-02-14 Paul Eggert <eggert@twinsun.com>
18246 Remove the support for C++ namespace cleanliness; it was
18247 causing more problems than it was curing, since it didn't work
18248 properly on some nonstandard C++ compilers. This can wait
18249 for a proper C++ parser.
18251 * NEWS: Document this.
18252 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
18253 of C++, as it's treated like C now.

18267 2002-02-13 Andreas Schwab <schwab@suse.de>
18269 * src/output.c (output_rule_data): Don't output NULL, it might
18270 not be defined yet.
18272 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
18274 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
18275 (Copyright notice): Update.

18289 * tests/input.at: New.
18291 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18293 * data/bison.c++: Replace some direct m4 expansions by constants. Be
18294 more consistent when naming methods and variables. Put preprocessor
18295 directives around tables only needed for debugging.
18297 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18299 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
18301 (yy::b4_name::parse): Use print_.
18303 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18305 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
18307 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18309 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
18311 (yy::b4_name::parse): Build verbose error messages, and use error_.
18313 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
18315 * data/bison.c++: Fix m4 quoting in comments.
18317 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
18319 * data/bison.c++: Adjust the parser code. Fix some muscles that were
18320 not expanded by m4.
18322 2002-02-05 Akim Demaille <akim@epita.fr>
18324 * data/bison.c++: Adjust to the M4 back end.
18325 More is certainly needed.
18327 2002-02-05 Akim Demaille <akim@epita.fr>
18329 Give a try to M4 as a back end.
18331 * lib/readpipe.c: New, from wdiff.
18332 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
18334 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
18335 specific values. Now it is m4 that performs the lookup.
18336 * src/parse-skel.y: Remove.
18337 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
18338 * src/output.c (actions_output, guards_output)
18339 (token_definitions_output): No longer keeps track of the output
18340 line number, hence remove the second argument.
18341 (guards_output): Check against the guard member of a rule, not the
18344 (output_skeleton): Don't look for the skeleton location, let m4 do
18346 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
18348 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
18349 (prepare): Given that for the time being changesyntax is not
18350 usable in M4, rename the muscles using `-' to `_'.
18351 Define `defines_flag', `output_parser_name' and `output_header_name'.
18352 * src/output.h (actions_output, guards_output)
18353 (token_definitions_output): Adjust prototypes.
18354 * src/scan-skel.l: Instead of scanning the skeletons, it now
18355 processes the output of m4: `__oline__' and `#output'.
18356 * data/bison.simple: Adjust to be used by M4(sugar).
18357 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
18359 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
18360 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
18361 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
18362 shamelessly stolen from CVS Autoconf.
18364 2002-02-05 Akim Demaille <akim@epita.fr>
18366 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
18367 * configure.in: Check for the declarations of free and malloc.
18368 * src/muscle_tab.c: Adjust.
18370 2002-02-05 Akim Demaille <akim@epita.fr>
18372 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
18373 which have no values.
18375 2002-02-05 Akim Demaille <akim@epita.fr>
18377 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
18380 2002-01-29 Paul Eggert <eggert@twinsun.com>
18382 * src/bison.simple (YYSIZE_T): Do not define merely because
18383 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
18384 On some platforms, <alloca.h> does not declare YYSTD (size_t).
18386 2002-01-27 Akim Demaille <akim@epita.fr>
18388 Fix `%nonassoc and eof'.
18390 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
18391 which were not properly copied! Replace
18392 memcpy (res->errs, src->errs, src->nerrs);
18394 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
18396 * tests/regression.at (%nonassoc and eof): Adjust to newest
18397 Autotest: `.' is not in the PATH.
18399 2002-01-27 Akim Demaille <akim@epita.fr>
18401 * tests/sets.at (AT_EXTRACT_SETS): New.
18402 (Nullable): Use it.
18405 2002-01-26 Akim Demaille <akim@epita.fr>
18407 * tests/actions.at, tests/calc.at, tests/headers.at,
18408 * tests/torture.at: Adjust to the newest Autotest which no longer
18409 forces `.' in the PATH.
18411 2002-01-25 Akim Demaille <akim@epita.fr>
18413 * tests/regression.at (%nonassoc and eof): New.
18414 Suggested by Robert Anisko.
18416 2002-01-24 Akim Demaille <akim@epita.fr>
18418 Bison dumps core when trying to complain about broken input files.
18419 Reported by Cris van Pelt.
18421 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
18422 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
18424 (Invalid inputs): Strengthen: exercise parse_percent_token.
18426 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
18428 * src/Makefile.am: Add bison.c++.
18429 * src/bison.c++: New skeleton.
18431 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
18435 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
18437 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
18439 2002-01-20 Marc Autret <marc@gnu.org>
18441 * src/files.c (compute_output_file_names): Fix
18443 2002-01-20 Marc Autret <marc@gnu.org>
18445 * tests/output.at: New test.
18446 * src/files.c (compute_base_names): Don't map extensions when
18447 the YACC flag is set, use defaults.
18448 Reported by Evgeny Stambulchik.
18450 2002-01-20 Marc Autret <marc@gnu.org>
18452 * src/system.h: Need to define __attribute__ away for non-GCC
18453 compilers as well (i.e., the vendor C compiler).
18454 Suggested by Albert Chin-A-Young.
18456 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
18458 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
18459 canonical definition.
18460 * src/system.h: Use the canonical definition for PARAMS (avoids
18461 a conflict with the macro from lib/hash.h).
18463 2002-01-11 Akim Demaille <akim@epita.fr>
18465 * configure.in: Use AC_FUNC_STRNLEN.
18466 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
18468 2002-01-09 Akim Demaille <akim@epita.fr>
18470 * src/files.c, src/files.h (output_infix): New.
18471 (tab_extension): Remove.
18472 (compute_base_names): Compute the former, drop the latter.
18473 * src/output.c (prepare): Insert the muscles `output-infix', and
18475 * src/parse-skel.y (string, string.1): New.
18476 (section.header): Use it.
18477 (section.yacc): Remove.
18478 (prefix): Remove too.
18479 * src/scan-skel.l: Adjust.
18480 * src/bison.simple, src/bison.hairy: Adjust.
18482 2002-01-09 Akim Demaille <akim@epita.fr>
18484 * configure.in (WERROR_CFLAGS): Compute it.
18485 * src/Makefile.am (CFLAGS): Pass it.
18486 * tests/atlocal.in (CFLAGS): Idem.
18487 * src/files.c: Fix a few warnings.
18488 (get_extension_index): Remove, unused.
18490 2002-01-08 Akim Demaille <akim@epita.fr>
18492 * src/getargs.c (AS_FILE_NAME): New.
18493 (getargs): Use it to convert DOSish file names.
18494 * src/files.c (base_name): Rename as full_base_name to avoid
18495 clashes with `base_name ()'.
18496 (filename_split): New.
18497 (compute_base_names): N-th rewrite, using filename_split.
18499 2002-01-08 Akim Demaille <akim@epita.fr>
18501 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
18502 New, stolen from the Fileutils 4.1.
18503 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
18504 * configure.in: Check for the presence of memrchr, and of its
18507 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
18509 * lib/hash.h (__P): Added definition for this macro.
18510 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
18511 BUILT_SOURCES, to ensure they are generated first.
18512 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
18513 %error-verbose to allow bootstrapping with bison 1.30x.
18515 2002-01-06 Akim Demaille <akim@epita.fr>
18517 * src/reader.c (parse_braces): Don't fetch the next char, the
18518 convention is to fetch on entry.
18519 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
18520 'switch' without a following semicolon.
18521 * tests/regression.at (braces parsing): New.
18523 2002-01-06 Akim Demaille <akim@epita.fr>
18525 Bison is dead wrong in its RR conflict reports.
18527 * tests/torture.at (GNU Cim Grammar): New.
18528 * src/conflicts.c (count_rr_conflicts): Fix.
18530 2002-01-06 Akim Demaille <akim@epita.fr>
18532 Creating package.m4 from configure.ac causes too many problems.
18534 * tests/Makefile.am (package.m4): Create it by hand,
18535 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
18537 2002-01-06 Akim Demaille <akim@epita.fr>
18539 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
18542 2002-01-04 Paul Eggert <eggert@twinsun.com>
18544 * doc/bison.texinfo (Debugging):
18545 Remove YYSTDERR; it's no longer defined or used.
18546 Also, s/cstdio.h/cstdio/.
18548 2002-01-03 Akim Demaille <akim@epita.fr>
18550 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
18552 2002-01-03 Akim Demaille <akim@epita.fr>
18554 * src/parse-skel.y (process_skeleton): Don't bind the parser's
18555 tracing code to --trace, wait for a better --trace option, with
18558 2002-01-03 Akim Demaille <akim@epita.fr>
18560 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
18561 The ISO C++ standard is extremely clear about it: stderr is
18562 considered a macro, not a regular symbol (see table 94 `Header
18563 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
18564 Therefore std:: does not apply to it. It still does with fprintf.
18565 Also, s/cstdio.h/cstdio/.
18567 2002-01-03 Akim Demaille <akim@epita.fr>
18569 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
18570 for non system headers.
18572 2002-01-02 Akim Demaille <akim@epita.fr>
18574 Equip the skeleton chain with location tracking, runtime trace,
18575 pure parser and scanner.
18577 * src/parse-skel.y: Request a pure parser, locations, and prefix
18579 (%union): Having several members with the same type does not help
18580 type mismatches, simplify.
18581 (YYPRINT, yyprint): New.
18582 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
18583 (skel_error): this.
18585 * src/scan-skel.l: Adjust to these changes.
18586 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
18587 (LOCATION_PRINT, skel_control_t): New.
18589 2001-12-30 Akim Demaille <akim@epita.fr>
18591 * src/parse-skel.y: Get rid of the shift/reduce conflict:
18592 replace `gb' with BLANKS.
18593 * src/scan-skel.l: Adjust.
18595 2001-12-30 Akim Demaille <akim@epita.fr>
18597 * src/system.h: We don't need nor want bcopy.
18598 Throw away MS-DOS crap: we don't need getpid.
18599 * configure.in: We don't need strndup. It was even causing
18600 problems: because Flex includes the headers *before* us,
18601 _GNU_SOURCE is not defined by config.h, and therefore strndup was
18603 * lib/xstrndup.c: New.
18604 * src/scan-skel.l: Use it.
18605 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
18606 * src/parse-skel.y: Use %directives instead of #defines.
18608 2001-12-30 Akim Demaille <akim@epita.fr>
18610 * src/skeleton.h: New.
18611 * src/output.c (output_parser, output_master_parser): Remove, dead
18613 * src/output.h (get_lines_number, actions_output, guards_output)
18614 (token_definitions_output): Prototype them.
18615 * src/parse-skel.y: Add the license notice.
18616 Include output.h and skeleton.h.
18617 (process_skeleton): Returns void, and takes a single parameter.
18618 * src/scan-skel.l: Add the license notice.
18619 Include skeleton.h.
18620 Don't use %option yylineno: it seems that then Flex imagines
18621 REJECT has been used, and therefore it won't reallocate its
18622 buffers (which makes no other sense to me than a bug). It results
18623 in warnings for `unused: yy_flex_realloc'.
18625 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
18627 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)

18630 (MUSCLE_INSERT_PREFIX): Move from here...
18632 * src/bison.hairy: Add a section directive. Put braces around muscle
18633 names. This parser skeleton is still broken, but Bison should not
18634 choke on a bad muscle 'syntax'.

18638 * src/files.h (strsuffix, stringappend): Add declarations.
18639 (tab_extension): Add declaration.
18640 (short_base_name): Add declaration.
18642 * src/files.c (strsuffix, stringappend): No longer static. These
18643 functions are used in the skeleton parser.
18644 (tab_extension): New.
18645 (compute_base_names): Use the computations done in this function
18646 to guess if the generated parsers should have '.tab' in their
18648 (short_base_name): No longer static.
18650 * src/output.c (output_skeleton): New.
18651 (output): Disable call to output_master_parser, and give a try to
18652 a new skeleton handling system.

18654 (token_definitions_output, get_lines_number): No longer static.
18656 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
18658 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
18661 * src/parse-skel.y: New file.
18662 * src/scan-skel.l: New file.
18664 2001-12-29 Akim Demaille <akim@epita.fr>
18666 %name-prefix is broken.
18668 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
18669 Adjust all dependencies.
18670 * tests/headers.at (export YYLTYPE): Strengthen this test: use
18673 Renaming yylval but not yylloc is not consistent. Now we do.
18675 * src/bison.simple: Prefix yylloc if used.
18676 * doc/bison.texinfo (Decl Summary): Document that.
18678 2001-12-29 Akim Demaille <akim@epita.fr>
18680 * doc/bison.texinfo: Promote `%long-directive' over
18682 Remove all references to fixed-output-files, yacc is enough.
18684 2001-12-29 Akim Demaille <akim@epita.fr>
18686 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
18687 user prologue. These are defaults.
18688 * tests/actions.at (Mid-rule actions): Make sure the user can
18689 define YYDEBUG and YYERROR_VERBOSE.
18691 2001-12-29 Akim Demaille <akim@epita.fr>
18693 * src/output.c (header_output): Don't forget to export YYLTYPE and
18695 * tests/headers.at (export YYLTYPE): New, make sure it does.
18696 * tests/regression.at (%union and --defines, Invalid CPP headers):
18698 * tests/headers.at: here.
18700 2001-12-29 Akim Demaille <akim@epita.fr>
18702 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
18704 2001-12-29 Akim Demaille <akim@epita.fr>
18706 * tests/actions.at (Mid-rule actions): Output on a single line
18707 instead of several.
18709 2001-12-29 Akim Demaille <akim@epita.fr>
18711 * doc/bison.texinfo: Formatting changes.
18713 2001-12-29 Akim Demaille <akim@epita.fr>
18715 Don't store the token defs in a muscle, just be ready to output it
18716 on command. Now possible via `symbols'. Fixes a memory leak.
18718 * src/output.c (token_definitions_output): New.
18719 (output_parser, header_output): Use it.
18720 * src/reader.c (symbols_save): Remove.
18722 2001-12-29 Akim Demaille <akim@epita.fr>
18724 * src/bison.simple: Do not provide a default for YYSTYPE and
18725 YYLTYPE before the user's prologue. Otherwise it's hardly... a
18728 2001-12-29 Akim Demaille <akim@epita.fr>
18730 Mid-rule actions are simply... ignored!
18732 * src/reader.c (readgram): Be sure to attach mid-rule actions to
18733 the empty-rule associated to the dummy symbol, not to the host
18735 * tests/actions.at (Mid-rule actions): New.
18737 2001-12-29 Akim Demaille <akim@epita.fr>
18741 * src/reader.c (reader): Free grammar.
18743 2001-12-29 Akim Demaille <akim@epita.fr>
18747 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
18748 since it allocates it for each state, although only one is needed.
18749 (allocate_storage): Do it here.
18751 2001-12-29 Akim Demaille <akim@epita.fr>
18753 * src/options.h, src/options.c (create_long_option_table): Rename
18755 (long_option_table_new): this, with a clearer prototype.
18756 (percent_table): Remove, unused,
18757 * src/getargs.c (getargs): Adjust.
18759 2001-12-29 Akim Demaille <akim@epita.fr>
18761 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

18765 2001-12-29 Akim Demaille <akim@epita.fr>
18767 * src/lalr.c (build_relations): Rename `states' as `states1'.
18768 Sorry, I don't understand exactly what it is, no better name...
18770 2001-12-29 Akim Demaille <akim@epita.fr>
18772 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
18773 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

18789 * src/gram.c, src/gram.h (sprec, sassoc): Remove.

18795 Adjust all users to use symbols[i]->tag.
18797 2001-12-29 Akim Demaille <akim@epita.fr>
18799 * src/gram.h, src/gram.c (symbols): New, similar to state_table
18801 * src/reader.c (packsymbols): Fill this table.
18803 * src/conflicts.c (resolve_sr_conflict): Adjust.
18804 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
18806 Use symbols[i]->tag instead of tags[i].
18808 2001-12-29 Akim Demaille <akim@epita.fr>
18810 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
18811 In addition, put a comment in there, to replace...
18812 * tests/regression.at (%union and C comments): Remove.
18814 2001-12-29 Akim Demaille <akim@epita.fr>
18816 * tests/regression.at (Web2c Actions): Blindly move the actual
18817 output as expected output. The contents *seem* right to me, but I
18818 can't pretend reading perfectly parser tables... Nonetheless, all
18819 the other tests pass correctly, the table look OK, even though the
18820 presence of `$axiom' is to be noted: AFAICS it is useless (but
18823 2001-12-29 Akim Demaille <akim@epita.fr>
18825 * src/reader.c (readgram): Don't add the rule 0 if there were no
18826 rules read. In other words, add it _after_ having performed
18827 grammar sanity checks.
18828 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
18830 2001-12-29 Akim Demaille <akim@epita.fr>
18832 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
18833 visible, and some states have now a different number.
18835 2001-12-29 Akim Demaille <akim@epita.fr>
18837 * src/reader.c (readgram): Bind the initial rule's lineno to that
18839 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18840 (Solved SR Conflicts): Adjust rule 0's line number.
18842 2001-12-29 Akim Demaille <akim@epita.fr>
18844 Fix the `GAWK Grammar' failure.
18846 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18847 the reductions of the first state which was mistakenly confused
18848 with the final state because precisely final_state was initialized
18850 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18851 now noticed by Bison.
18852 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18853 have a reduction on $default.
18855 2001-12-29 Akim Demaille <akim@epita.fr>
18857 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18859 * src/closure.c (print_closure): Likewise.
18860 * src/derives.c (print_derives): Likewise.
18861 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18864 2001-12-29 Akim Demaille <akim@epita.fr>
18866 * src/lalr.c (lookaheads_print): New.
18867 (lalr): Call it when --trace-flag.
18868 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18871 2001-12-29 Akim Demaille <akim@epita.fr>
18873 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18874 when walking through ritem, even via rule->rhs.
18875 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18876 (useful_production, useless_nonterminals): Likewise.
18877 (reduce_grammar_tables): Likewise, plus update nritems.
18878 * src/nullable.c (set_nullable): Likewise.
18879 * src/lalr.c (build_relations): Likewise.
18880 * tests/sets.at (Nullable): Adjust.
18881 Fortunately, now, the $axiom is no longer nullable.
18883 2001-12-29 Akim Demaille <akim@epita.fr>
18885 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

18893 2001-12-29 Akim Demaille <akim@epita.fr>
18895 * src/output.c: Comment changes.
18897 2001-12-27 Paul Eggert <eggert@twinsun.com>
18899 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18900 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18901 Sparc, as they were causing more porting problems than the
18902 (minor) performance improvement was worth.
18904 Also, catch up with 1.31's YYSTD.
18906 2001-12-27 Akim Demaille <akim@epita.fr>
18908 * src/output.c (output_gram): Rely on nritems, not the
18909 0-sentinel. See below.
18910 Use -1 as separator, not 0.
18911 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18912 Rely on -1 as separator in yyrhs, instead of 0.
18913 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18914 twice `Now at end of input', therefore there are two lines less to
18917 2001-12-27 Akim Demaille <akim@epita.fr>
18919 * tests/regression.at (Unresolved SR Conflicts):
18920 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18923 2001-12-27 Akim Demaille <akim@epita.fr>
18925 * src/LR0.c (new_state): Recognize the final state by the fact it
18926 is reached by eoftoken.
18927 (insert_start_shifting_state, insert_eof_shifting_state)
18928 (insert_accepting_state, augment_automaton): Remove, since now
18929 these states are automatically computed from the initial state.
18930 (generate_states): Adjust.
18931 * src/print.c: When reporting a rule number to the user, substract
18932 1, so that the axiom rule is rule 0, and the first user rule is 1.
18933 * src/reduce.c: Likewise.
18934 * src/print_graph.c (print_core): For the time being, just as for
18935 the report, depend upon --trace-flags to dump the full set of
18937 * src/reader.c (readgram): Once the grammar read, insert the rule
18938 0: `$axiom: START-SYMBOL $'.
18939 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18940 number of the states has changed (the final state is no longer
18941 necessarily the last), catch up.
18943 2001-12-27 Akim Demaille <akim@epita.fr>
18945 Try to make the use of the eoftoken valid. Given that its value
18946 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18947 is used instead of > 0 where appropriate, (ii), depend upon nritems
18948 instead of the 0-sentinel.
18950 * src/gram.h, src/gram.c (nritems): New.
18951 Expected to be duplication of nitems, but for the time being...
18952 * src/reader.c (packgram): Assert nritems and nitems are equal.
18953 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18954 * src/closure.c (print_closure, print_fderives): Likewise.

18961 * src/main.c (main): If there are complains after grammar
18962 reductions, then output the report anyway if requested, then die.
18963 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18964 * src/reader.c (eoftoken): New.
18965 (parse_token_decl): If the token being defined has value `0', it
18967 (packsymbols): No longer hack `tags' to insert `$' by hand.
18968 Be sure to preserve the value of the eoftoken.
18969 (reader): Make sure eoftoken is defined.
18970 Initialize nsyms to 0: now eoftoken is created just like the others.
18971 * src/print.c (print_grammar): Don't special case the eof token.
18972 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18973 lie anyway, albeit pleasant.
18974 * tests/calc.at: Exercise error messages with eoftoken.
18975 Change the grammar so that empty input is invalid.
18976 Adjust expectations.
18977 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18979 2001-12-27 Akim Demaille <akim@epita.fr>
18981 * configure.in: Check the protos of strchr ans strspn.
18982 Replace strchr if needed.
18983 * src/system.h: Provide the protos of strchr, strspn and memchr if
18985 * lib/strchr.c: New.
18986 * src/reader.c (symbols_save): Use strchr.

18990 * src/print.c, src/print_graph.c (escape): New.
18991 Use it to quote the TAGS outputs.
18992 * src/print_graph.c (print_state): Now errors are in red, and
18993 reductions in green.
18994 Prefer high to wide: output the state number on a line of its own.
18996 2001-12-27 Akim Demaille <akim@epita.fr>
18998 * src/state.h, src/state.c (reductions_new): New.

19052 * src/output.c (output): Adjust.
19053 * src/reader.c (parse_braces): New, factoring...
19054 (copy_action, copy_guard): these two which are renamed as...
19055 (parse_action, parse_guard): these.
19056 As a voluntary consequence, using braces around guards is now
19059 2001-12-27 Akim Demaille <akim@epita.fr>
19061 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
19062 * src/reader.c (symbol_list): `guard' and `guard_line' are new
19064 (symbol_list_new): Adjust.
19065 (copy_action): action_line is the first line, not the last.
19066 (copy_guard): Just as for actions, store the `action' only, not
19067 the switch/case/break flesh.
19068 Don't parse the user action that might follow the guard, let...
19069 (readgram): do it, i.e., now, there can be an action after a
19071 In other words the guard is just explicitly optional.
19072 (packgram): Adjust.
19073 * src/output.c (guards_output): New.
19074 (output_parser): Call it when needed.
19075 (output): Also free the guard and attrs obstacks.
19076 * src/files.c, src/files.h (obstack_save): Remove.
19077 (output_files): Remove.
19078 As a result, if one needs the former `.act' file, using an
19079 appropriate skeleton which requires actions and guards is now
19081 * src/main.c (main): Adjust.
19082 * tests/semantic.at: New.
19083 * tests/regression.at: Use `input.y' as input file name.

19089 * src/reader.c (symbol_list_new): Be sure to initialize all the
19092 2001-12-27 Akim Demaille <akim@epita.fr>
19094 All the hacks using a final pseudo state are now useless.
19096 * src/LR0.c (set_state_table): state_table holds exactly nstates.
19097 * src/lalr.c (nLA): New.
19098 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
19099 instead of lookaheadsp from the pseudo state (nstate + 1).
19101 2001-12-27 Akim Demaille <akim@epita.fr>
19103 * src/output.c (action_row, token_actions): Use a state_t instead
19104 of a integer, and nlookaheads instead of the following state's

19111 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
19112 (conflicts_print, print_reductions): Use a state_t instead of an
19113 integer when referring to a state.
19114 As much as possible, depend upon nlookaheads, instead of the
19115 `lookaheadsp' member of the following state (since lookaheads of
19116 successive states are successive, the difference between state n + 1
19117 and n served as the number of lookaheads for state n).
19118 * src/lalr.c (add_lookback_edge): Likewise.
19119 * src/print.c (print_core, print_actions, print_state)
19120 (print_results): Likewise.
19121 * src/print_graph.c (print_core, print_actions, print_state)
19122 (print_graph): Likewise.
19123 * src/conflicts.h: Adjust.
19125 2001-12-27 Akim Demaille <akim@epita.fr>
19127 * src/bison.hairy: Formatting/comment changes.
19129 Remove `register' indications.
19130 Add plenty of `static'.
19132 2001-12-27 Akim Demaille <akim@epita.fr>
19134 * src/output.c (prepare): Drop the muscle `ntbase' which
19135 duplicates ntokens.
19136 * src/bison.simple: Formatting/comment changes.
19137 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
19138 is an undocumented synonym.
19140 2001-12-22 Akim Demaille <akim@epita.fr>
19142 * src/output.c (output_table_data): Change the prototype to use
19143 `int' for array ranges: some invocations do pass an int, not a
19145 Reported by Wayne Green.
19147 2001-12-22 Akim Demaille <akim@epita.fr>
19149 Some actions of web2c.y are improperly triggered.
19150 Reported by Mike Castle.
19152 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
19153 * tests/regression.at (Web2c): Rename as...
19154 (Web2c Report): this.
19155 (Web2c Actions): New.
19157 2001-12-22 Akim Demaille <akim@epita.fr>
19159 Reductions in web2c.y are improperly reported.
19160 Reported by Mike Castle.
19162 * src/conflicts.c (print_reductions): Fix.
19163 * tests/regression.at (Web2c): New.
19165 2001-12-18 Akim Demaille <akim@epita.fr>
19167 Some host fail on `assert (!"foo")', which expands to
19168 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
19169 Reported by Nelson Beebee.
19171 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
19172 `#define it_succeeded 0' and `assert (it_succeeded)'.
19174 2001-12-17 Marc Autret <autret_m@epita.fr>
19176 * src/bison.simple: Don't hard code the skeleton line and filename.
19177 * src/output.c (output_parser): Rename 'line' as 'output_line'.
19178 New line counter 'skeleton_line' (skeleton-line muscle).
19180 2001-12-17 Paul Eggert <eggert@twinsun.com>
19182 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
19183 YYDEBUG must be defined to a nonzero value.
19185 * src/bison.simple (yytname): Do not assume that the user defines
19186 YYDEBUG to a properly parenthesized expression.
19188 2001-12-17 Akim Demaille <akim@epita.fr>
19190 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
19191 nlookaheads is a new member.
19193 * src/lalr.h (nlookaheads): Remove this orphan declaration.
19194 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
19197 2001-12-17 Akim Demaille <akim@epita.fr>
19199 * src/files.h, src/files.c (open_files, close_files): Remove.
19200 * src/main.c (main): Don't open/close files, nor invoke lex_free,
19202 * src/reader.c (reader): Do it.
19204 2001-12-17 Akim Demaille <akim@epita.fr>
19206 * src/conflicts.c (print_reductions): Formatting changes.
19208 2001-12-17 Akim Demaille <akim@epita.fr>
19210 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
19211 (flush_reduce): New.
19212 (resolve_sr_conflict): Adjust.
19214 2001-12-17 Akim Demaille <akim@epita.fr>
19216 * src/output.c (output_obstack): Be static and rename as...
19217 (format_obstack): this, to avoid any confusion with files.c's
19219 * src/reader.h (muscle_obstack): Move to...
19220 * src/output.h: here, since it's defined in output.c.
19222 2001-12-17 Akim Demaille <akim@epita.fr>
19224 * src/output.c (action_row, save_column, default_goto)
19225 (sort_actions, matching_state, pack_vector): Better variable
19228 2001-12-17 Akim Demaille <akim@epita.fr>
19230 * src/output.c: Various formatting changes.
19232 2001-12-17 Akim Demaille <akim@epita.fr>
19234 * src/files.c (output_files): Free the output_obstack.
19235 * src/main.c (main): Call print and print_graph conditionally.
19236 * src/print.c (print): Work unconditionally.
19237 * src/print_graph.c (print_graph): Work unconditionally.
19238 * src/conflicts.c (log_resolution): Output only if verbose_flag.
19240 2001-12-16 Marc Autret <autret_m@epita.fr>
19242 * src/output.c (actions_output): Fix. When we use %no-lines,
19243 there is one less line per action.
19245 2001-12-16 Marc Autret <autret_m@epita.fr>
19247 * src/bison.simple: Remove a useless #line directive.
19248 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
19249 * src/output.c (get_lines_number): New.
19250 (output_parser): Adjust, now takes care about the lines of a
19252 Fix line numbering.
19253 (actions_output): Computes the number of lines taken by actions.
19254 (output_master_parser): Insert new skeleton which is the name of
19255 the output parser file name.
19257 2001-12-15 Marc Autret <autret_m@epita.fr>
19259 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
19261 2001-12-15 Marc Autret <autret_m@epita.fr>
19263 * src/output.c (output_gram): Keep track of the hairy one.
19265 2001-12-15 Akim Demaille <akim@epita.fr>
19267 Make `make distcheck' work.
19269 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
19270 system.h which uses libgettext.h.
19272 2001-12-15 Akim Demaille <akim@epita.fr>
19274 * src/nullable.c (set_nullable): Useless rules must be skipped,
19275 otherwise, since we range over their symbols, we might look at a
19276 nonterminal which no longer ``exists'', i.e., it is not counted in
19277 `nvars', hence we overflow our arrays.
19279 2001-12-15 Akim Demaille <akim@epita.fr>
19281 The header can also be produced directly, without any obstack!
19284 * src/files.c, src/files.h (defines_obstack): Remove.
19285 (compute_header_macro): Global.
19286 (defines_obstack_save): Remove.
19287 * src/reader.c (parse_union_decl): No longer output to
19288 defines_obstack: its content can be found in the `stype' muscle
19290 (output_token_translations): Merge into...
19291 (symbols_output): this.
19293 (symbols_save): this.
19295 * src/output.c (header_output): New.
19298 2001-12-15 Akim Demaille <akim@epita.fr>
19300 * src/reader.c (parse_union_decl): Instead of handling two obstack
19301 simultaneously, use one to define the `stype' muscle, and use the
19302 value of the latter to fill defines_obstack.
19303 (copy_comment): Remove.
19304 (copy_comment2): Work for a single obstack.
19306 (copy_comment): this.
19308 2001-12-15 Akim Demaille <akim@epita.fr>
19310 * src/lex.c, src/lex.h (xgetc): No longer static.
19311 * src/reader.c (parse_union_decl): Revamp.
19313 2001-12-15 Akim Demaille <akim@epita.fr>
19315 Still making progress in separating Bison into (i) input, (ii)
19316 process, (iii) output: now we can directly output the parser file
19317 without using table_obstack at all.
19319 * src/files.c, src/files.h (table_obstack): Bye bye.
19320 (parser_file_name): New.
19321 * src/files.c (compute_output_file_names): Compute it.
19322 * src/output.c (actions_output, output_parser)
19323 (output_master_parser): To a file instead of an obstack.
19325 2001-12-15 Akim Demaille <akim@epita.fr>
19327 Attach actions to rules, instead of pre-outputting them to
19330 * src/gram.h (rule_t): action and action_line are new members.
19331 * src/reader.c (symbol_list): Likewise.
19332 (copy_action): Save the actions within the rule.
19333 (packgram): Save them in rule_table.
19334 * src/output.c (actions_output): New.
19335 (output_parser): Use it on `%%actions'.
19336 (output_rule_data): Don't free rule_table.
19338 (prepare): Don't save the `action' muscle.
19339 * src/bison.simple: s/%%action/%%actions/.
19341 2001-12-15 Akim Demaille <akim@epita.fr>
19343 * src/reader.c (copy_action): When --yacc, don't append a `;'
19344 to the user action: let it fail if lacking.
19345 Suggested by Arnold Robbins and Tom Tromey.
19347 2001-12-14 Akim Demaille <akim@epita.fr>
19349 * src/lex.c (literalchar): Simply return the char you decoded, non
19350 longer mess around with obstacks and int pointers.
19351 Adjust all callers.
19353 2001-12-14 Akim Demaille <akim@epita.fr>
19355 * src/lex.c (literalchar): Don't escape the special characters,
19356 just decode them, and keep them as char (before, eol was output as
19357 the 2 char string `\n' etc.).
19358 * src/output.c (output_rule_data): Use quotearg to output the
19361 2001-12-13 Paul Eggert <eggert@twinsun.com>
19363 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
19364 Do not infringe on the global user namespace when using C++.
19365 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
19366 All uses of `fprintf' and `stderr' changed.
19368 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
19370 2001-12-13 Akim Demaille <akim@epita.fr>
19372 The computation of nullable is broken: it doesn't handle empty
19375 * tests/torture.at (GNU AWK Grammar): New.
19376 * tests/sets.at (Nullable): New.
19377 * src/nullable.c (set_nullable): Instead of blindly looping over
19378 `ritems', loop over the rules, and then over their rhs's.
19380 Work around Autotest bugs.
19382 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
19383 frame, because Autotest understand lines starting with a `+' as
19384 traces from the shell. Then, they are not processed properly.
19385 Admittedly an Autotest bug, but we don't have time to wait for
19386 Autotest to catch up.
19387 * tests/regression.at (Broken Closure): Adjust to the new table
19390 * tests/sets.at: here.
19392 2001-12-13 Akim Demaille <akim@epita.fr>
19394 * src/closure.c (closure): Use nrules instead of playing tricks
19395 with BITS_PER_WORD.
19397 2001-12-13 Akim Demaille <akim@epita.fr>
19399 * src/print.c (print_actions): Output the handling of `$' as the
19400 traces do: shifting the token EOF. Before EOF was treated as a
19402 * tests/regression.at: Adjust some tests.
19403 * src/print_graph.c (print_core): Complete the set of items via
19404 closure. The next-to-final and final states are still unsatisfying,
19405 but that's to be addressed elsewhere.
19406 No longer output the rule numbers, but do output the state number.
19407 A single loop for the shifts + gotos is enough, but picked a
19408 distinct color for each.
19409 (print_graph): Initialize and finalize closure.
19411 2001-12-13 Akim Demaille <akim@epita.fr>
19413 * src/reader.c (readgram): Remove dead code, an strip useless
19415 (get_type): Remove, unused.
19417 2001-12-12 Akim Demaille <akim@epita.fr>
19419 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
19420 on that of lib/error.c.
19422 2001-12-12 Akim Demaille <akim@epita.fr>
19424 Some hosts don't like `/' in includes.
19426 * src/system.h: Include libgettext.h without qualifying the path.
19427 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
19430 2001-12-11 Marc Autret <autret_m@epita.fr>
19432 * src/output.c (output_parser): Remove useless muscle.
19434 2001-12-11 Marc Autret <autret_m@epita.fr>
19436 * src/bison.simple: Remove #line just before %%epilogue. It
19437 is now handled in ...
19438 * src/reader.c (read_additionnal_code): Add the output of a
19439 #line for the epilogue.
19441 2001-12-10 Marc Autret <autret_m@epita.fr>
19443 * src/reader.c (copy_definition): Re-use CPP-outed code which
19444 replace precedent remove.
19445 * src/bison.simple: Remove #line before %%prologue because
19446 %%input-line is wrong at this time.
19448 2001-12-10 Marc Autret <autret_m@epita.fr>
19450 * src/reader.c (symbols_output): Clean up.
19451 * src/output.c (output_gram, output): Clean up.
19453 2001-12-10 Akim Demaille <akim@epita.fr>
19455 * src/lalr.c (initialize_lookaheads): New. Extracted from...
19456 * src/LR0.c (set_state_table): here.
19457 * src/lalr.c (lalr): Call it.
19459 2001-12-10 Akim Demaille <akim@epita.fr>
19461 * src/state.h (shifts): Remove the `number' member: shifts are
19462 attached to state, hence no longer need to be labelled with a
19465 2001-12-10 Akim Demaille <akim@epita.fr>
19467 Now that states have a complete set of members, the linked list of
19468 shifts is useless: just fill directly the state's shifts member.
19470 * src/state.h (shifts): Remove the `next' member.
19471 * src/LR0.c (first_state, last_state): Remove.
19472 Adjust the callers.
19473 (augment_automaton): Don't look for the shifts that must be added
19474 a shift on EOF: it is those of the state we looked for! But now,
19475 since shifts are attached, it is no longer needed to looking
19476 merely by its id: its number.
19478 2001-12-10 Akim Demaille <akim@epita.fr>
19480 * src/LR0.c (augment_automaton): Better variable locality.
19481 Remove an impossible branch: if there is a state corresponding to
19482 the start symbol being shifted, then there is shift for the start
19483 symbol from the initial state.
19485 2001-12-10 Akim Demaille <akim@epita.fr>
19487 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
19488 only when appropriate: when insert_start_shifting_state' is not
19490 * tests/regression.at (Rule Line Numbers): Adjust.
19492 2001-12-10 Akim Demaille <akim@epita.fr>
19494 * src/LR0.c (augment_automaton): Now that all states have shifts,
19495 merge the two cases addition shifts to the initial state.
19497 2001-12-10 Akim Demaille <akim@epita.fr>
19499 * src/lalr.c (set_state_table): Move to...
19501 * src/lalr.c (lalr): Don't call it...
19502 * src/LR0.c (generate_states): do it.
19503 * src/LR0.h (first_state): Remove, only the table is used.
19505 2001-12-10 Akim Demaille <akim@epita.fr>
19507 * src/LR0.h (first_shift, first_reduction): Remove.
19508 * src/lalr.c: Don't use first_shift: find shifts through the
19511 2001-12-10 Akim Demaille <akim@epita.fr>
19513 * src/LR0.c: Attach shifts to states as soon as they are
19515 * src/lalr.c (set_state_table): Instead of assigning shifts to
19516 state, just assert that the mapping was properly done.
19518 2001-12-10 Akim Demaille <akim@epita.fr>
19520 * src/LR0.c (insert_start_shift): Rename as...
19521 (insert_start_shifting_state): this.
19522 (insert_eof_shifting_state, insert_accepting_state): New.
19523 (augment_automaton): Adjust.
19524 Better locality of the variables.
19525 When looking if the start_symbol is shifted from the initial
19526 state, using `while (... symbol != start_symbol ...)' sounds
19527 better than `while (... symbol < start_symbol ...)': If fail
19528 to see how the order between symbols could be relevant!
19530 2001-12-10 Akim Demaille <akim@epita.fr>
19532 * src/getargs.h: Don't declare `spec_name_prefix' and
19533 `spec_file_prefix', declared by src/files.h.
19534 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
19535 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
19536 * src/output.c (prepare): Adjust.
19537 * src/reader.c (symbols_output): Likewise.
19538 * src/vmsgetargs.c: Vaguely adjust, but who cares?
19540 2001-12-10 Akim Demaille <akim@epita.fr>
19542 * src/muscle_tab.c (muscle_init): NULL is a better default than
19545 2001-12-10 Akim Demaille <akim@epita.fr>
19547 * src/reader.c (reader): Calling symbols_output once is enough.
19549 2001-12-10 Akim Demaille <akim@epita.fr>
19551 Now that states have a complete set of members, the linked list of
19552 reductions is useless: just fill directly the state's reductions
19555 * src/state.h (struct reductions): Remove member `number' and
19557 * src/LR0.c (first_reduction, last_reduction): Remove.
19558 (save_reductions): Don't link the new reductions, store them in
19560 * src/lalr.c (set_state_table): No need to attach reductions to
19561 states, it's already done.
19562 * src/output.c (output_actions): No longer free the shifts, then
19563 the reductions, then the states: free all the states and their
19566 2001-12-10 Akim Demaille <akim@epita.fr>
19568 * src/options.c (OPTN, DRTV, BOTH): New.
19569 (option_table): Use them.
19571 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
19572 the job of system.h.
19573 * src/options.c: Don't include stdio.h and xalloc.h for the same
19576 2001-12-10 Akim Demaille <akim@epita.fr>
19578 * src/output.c (output, prepare): Make sure the values of the
19579 muscles `action' and `prologue' are 0-terminated.
19581 2001-12-10 Akim Demaille <akim@epita.fr>
19583 Clean up GCC warnings.
19585 * src/reader.c (copy_action): `buf' is not used.
19586 (parse_skel_decl): Be static.
19587 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
19588 * src/options.h (create_long_option_table): Have a real prototype.
19589 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
19590 (hash_delete_at): Return const void *.
19591 Adjust casts to preserve the const.
19593 2001-12-10 Akim Demaille <akim@epita.fr>
19595 * configure.in: Require 2.52g.
19596 M4 is not needed, but AUTOM4TE is.
19597 * m4/m4.m4: Remove.
19598 * tests/Makefile.am: Adjust.
19600 2001-12-10 Akim Demaille <akim@epita.fr>
19602 One structure for states is enough, even though theoretically
19603 there are LR(0) states and LALR(1) states.
19605 * src/lalr.h (state_t): Remove.
19606 (state_table): Be state_t **, not state_t *.
19607 * src/state.h (core, CORE_ALLOC): Rename as...
19608 (state_t, STATE_ALLOC): this.
19609 Add the LALR(1) members: shifts, reductions, errs.
19610 * src/LR0.c (state_table): Rename as...
19611 (state_hash): this, to avoid name clashes with the global
19613 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
19614 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
19616 2001-12-10 Akim Demaille <akim@epita.fr>
19618 Bison dumps core on bash.y.
19619 Reported by Pascal Bart.
19621 * src/warshall.c (bitmatrix_print): New.
19623 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
19624 j must be the outer loop.
19625 * tests/regression.at (Broken Closure): New.
19627 2001-12-05 Akim Demaille <akim@epita.fr>
19629 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
19631 Reported by Peter Hamorsky.
19633 2001-12-05 Akim Demaille <akim@epita.fr>
19635 * src/conflicts.c (err_table): Remove.
19636 (resolve_sr_conflict): Adjust.
19637 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
19639 (state_t.reductions, state_t.shifts): this.
19641 2001-12-05 Akim Demaille <akim@epita.fr>
19643 * src/reduce.c (reduce_grammar_tables): No longer disable the
19644 removal of useless rules via CPP but via `if (0)', so that the
19645 compiler still check the code is valid.
19646 For instance, it should have noticed `rline' no longer exists: use
19647 the `line' member of rule_t.
19648 * src/gram.c (dummy, rline): Remove, unused.
19650 2001-12-05 Akim Demaille <akim@epita.fr>
19652 * src/output.c (pack_vector): Use assert, not berror.
19653 * src/main.c (berror): Remove, unused.
19655 2001-12-05 Akim Demaille <akim@epita.fr>
19657 New experimental feature: if --verbose --trace output all the
19658 items of a state, not only its kernel.
19660 * src/print.c (print_core): If `trace_flag', then invoke closure
19661 before outputting the items of the state (print_core is no longer
19662 a correct name them).
19663 (print_results): Invoke new_closure/free_closure if needed.
19665 2001-12-05 Akim Demaille <akim@epita.fr>
19667 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
19668 * src/closure.c, src/closure.h (itemsetsize): Rename as...
19669 (nitemset): for consistency with the rest of the project.

19674 (closure): Use it for printing input and output.
19676 2001-12-05 Akim Demaille <akim@epita.fr>
19678 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
19679 indexed by nonterminals.
19681 2001-12-05 Akim Demaille <akim@epita.fr>
19683 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

19699 2001-12-05 Akim Demaille <akim@epita.fr>
19701 * src/output.c (action_row): De-obfuscate
19702 using the good o' techniques: arrays not pointers, variable
19703 locality, BITISSET, RESETBIT etc.
19705 2001-12-05 Akim Demaille <akim@epita.fr>
19707 Pessimize the code to simplify it: from now on, all the states
19708 have a valid SHIFTS, which NSHIFTS is possibly 0.
19710 * src/LR0.c (shifts_new): Be global and move to..
19711 * src/state.c, src/state.h: here.
19712 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
19713 * src/print_graph: Adjust.
19715 2001-12-05 Akim Demaille <akim@epita.fr>
19717 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
19718 * src/conflicts.c: Use it.
19719 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
19720 incorrectly ``simplified''.
19722 2001-12-05 Akim Demaille <akim@epita.fr>
19724 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
19725 using the good o' techniques: arrays not pointers, variable
19726 locality, BITISSET, RESETBIT etc.
19728 2001-12-05 Akim Demaille <akim@epita.fr>
19730 * src/state.h (SHIFT_SYMBOL): New.
19731 * src/conflicts.c: Use it to deobfuscate.
19733 2001-12-05 Akim Demaille <akim@epita.fr>
19735 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
19736 (print_reductions): De-obfuscate using the good o' techniques:

19760 2001-12-05 Akim Demaille <akim@epita.fr>
19762 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
19763 * src/lalr.c: Use them.
19765 2001-12-05 Akim Demaille <akim@epita.fr>
19767 * src/LR0.c (augment_automaton): Formatting changes.
19768 Better variable locality.

19772 * src/lalr.c (matrix_print): New.
19773 (transpose): Use it.

19778 * src/lalr.c (maxrhs): Move to...
19779 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
19780 * src/lalr.c (build_relations): Adjust.
19782 2001-12-05 Akim Demaille <akim@epita.fr>
19784 * src/lalr.c (transpose): Free the memory allocated to the
19785 argument, as it is replaced by the results by the unique caller.
19786 (build_relations): Merely invoke transpose: it handles the memory
19788 Improve variable locality.
19789 Avoid variables used as mere abbreviations.
19790 (compute_lookaheads): Use arrays instead of pointers.
19792 2001-12-05 Akim Demaille <akim@epita.fr>
19794 * src/lalr.c (initialize_F): Improve variable locality.
19795 Avoid variables used as mere abbreviations.
19797 2001-12-05 Akim Demaille <akim@epita.fr>
19799 * src/derives.c (print_derives): Display the ruleno.
19800 * src/lalr.c (initialize_F, transpose): Better variable locality

19808 2001-12-05 Akim Demaille <akim@epita.fr>
19810 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
19811 the handling of squeue.
19812 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19814 2001-12-05 Akim Demaille <akim@epita.fr>
19816 Because useless nonterminals are now kept alive (instead of being
19817 `destroyed'), we now sometimes examine them, and store information
19818 related to them. Hence we need to know their number, and adjust
19819 memory allocations.
19821 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19823 * src/LR0.c (allocate_itemsets): The memory allocated to
19824 `symbol_count' was used for two different purpose: once to count
19825 the number of occurrences of each symbol, and later reassigned to
19826 `shift_symbol', containing the symbol that can be shifted from a
19828 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19830 (new_itemsets): Allocate `shift_symbol' here.
19831 (allocate_itemsets): symbol_count includes useless nonterminals.
19832 Make room for them.
19833 (free_storage): Use `free', not `XFREE', for pointers that cannot
19836 2001-12-05 Akim Demaille <akim@epita.fr>
19838 * src/nullable.c (set_nullable): Deobfuscate the handling of
19840 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19842 2001-12-05 Akim Demaille <akim@epita.fr>
19844 * src/gram.c, src/gram.h (ritem_print): New.
19845 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19846 (This useless function was defined only to work around VMS linkers
19847 that can't handle compilation units with variables only).
19848 * src/reduce.c (dump_grammar): Use it to trace the construction of
19851 2001-12-04 Paul Eggert <eggert@twinsun.com>
19853 * src/bison.simple (union yyalloc): Change member names
19854 to be the same as the stack names.
19855 (yyparse): yyptr is now union yyalloc *, not char *.
19856 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19857 and may generate better code on some machines.
19858 (yystpcpy): Use prototype if __STDC__ is defined, not just
19859 if __cplusplus is defined.
19861 2001-11-30 Akim Demaille <akim@epita.fr>
19863 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19864 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
19865 Gettext doesn't compile cleanly, and dies with -Werror.
19866 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
19867 Include WARNING_CFLAGS here.
19868 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
19869 before being defined.
19871 2001-11-27 Paul Eggert <eggert@twinsun.com>
19873 * lib/quotearg.h (quotearg_n, quotearg_n_style):
19874 First arg is int, not unsigned.
19875 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
19876 (SIZE_MAX, UINT_MAX): New macros.
19877 (quotearg_n_options): Abort if N is negative.
19878 Avoid overflow check on hosts where size_t is 64 bits and int
19879 is 32 bits, as overflow is impossible there.
19880 Fix off-by-one typo that caused unnecessary reallocation.
19882 2001-11-29 Paul Eggert <eggert@twinsun.com>
19884 Name space cleanup in generated parser.
19886 * doc/bison.texinfo (Bison Parser): Discuss system headers
19887 and their effect on the user name space.
19889 * src/bison.simple:
19890 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19891 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19892 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19894 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
19895 on user names when possible.
19897 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
19898 Simplify test for whather <alloca.h> exists.
19900 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
19902 (<stdio.h>): Include if YYDEBUG.
19904 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
19905 ! defined (yyoverflow) && ! defined (yymemcpy).
19907 (yymemcpy, yyparse): Rename local variables as needed so that
19908 they all begin with 'yy'.
19910 (yystrlen, yystpcpy): New functions.
19912 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
19915 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
19916 instead of relying on string.h functions. Use YYSTACK_ALLOC
19917 and YYSTACK_FREE instead of malloc and free.
19919 2001-11-30 Akim Demaille <akim@epita.fr>
19921 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
19922 before their first uses.

19929 2001-11-30 Akim Demaille <akim@epita.fr>
19931 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
19932 if body instead of `;' to pacify GCC's warnings.
19934 2001-11-30 Akim Demaille <akim@epita.fr>
19936 Instead of mapping the LHS of unused rules to -1, keep the LHS
19937 valid, but flag the rules as invalid.
19939 * src/gram.h (rule_t): `useful' is a new member.
19940 * src/print.c (print_grammar): Adjust.
19941 * src/derives.c (set_derives): Likewise.
19942 * src/reader.c (packgram, reduce_output): Likewise.
19943 * src/reduce.c (reduce_grammar_tables): Likewise.
19944 * tests/reduce.at (Underivable Rules, Useless Rules): New.
19946 2001-11-30 Akim Demaille <akim@epita.fr>

19957 (reduce_output): Adjust.
19958 * tests/reduce.at (Useless Nonterminals): Adjust.
19960 2001-11-30 Akim Demaille <akim@epita.fr>

19970 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
19971 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
19973 (union yyalloc): New type.
19974 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
19975 an arbitrary restriction on hosts where size_t is wider than int.
19977 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19978 a parser stack overflow. Allocate just one block of memory for all
19979 three stacks, instead of allocating three blocks; this typically is
19980 faster and reduces fragmentation.
19982 Do not limit the number of items in the stack to a value that fits
19983 in 'int', as this is an arbitrary limit on hosts with 64-bit
19984 size_t and 32-bit int.
19986 2001-11-29 Marc Autret <autret_m@epita.fr>
19988 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
19989 of defining YYERROR_VERBOSE.

20039 2001-11-28 Akim Demaille <akim@epita.fr>
20041 * src/closure.c (closure): Instead of looping over word in array
20042 then bits in words, loop over bits in array.
20044 2001-11-28 Akim Demaille <akim@epita.fr>
20046 * src/closure.c (closure): No longer optimize the special case
20047 where all the bits of `ruleset[r]' are set to 0, to make the code
20050 2001-11-28 Akim Demaille <akim@epita.fr>
20052 * src/closure.c (closure): `r' and `c' are new variables, used to

20069 From Enrico Scholz.
20071 2001-11-27 Paul Eggert <eggert@twinsun.com>
20073 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
20074 use alloca when we didn't want to, and vice versa.

21795 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
21796 New, from fileutils 4.0.37.
21797 * configure.in: Require Autoconf 2.49c. I took some time before
21798 making this decision. This is the only way out for portability
21799 issues in Bison, it would mean way too much duplicate effort to
21800 import in Bison features implemented in 2.49c since 2.13.

21848 introduces a guaranteed SEGV for semantic parsers.

22212 The location tracking mechanism is precious for parse error
22213 messages. Nevertheless, it is enabled only when `@n' is used in
22214 the grammar, which is a different issue (you can use it in error
22215 message, but not in the grammar per se). Therefore, there should
22216 be another means to enable it.
22218 * src/getargs.c (getargs): Support `--locations'.
22219 (usage): Report it.
22220 * src/getargs.h (locationsflag): Export it.
22221 * src/lex.c (percent_table): Support `%locations'.
22222 * src/reader.c (yylsp_needed): Remove this variable, now replaced
22223 with `locationsflag'.
22224 * doc/bison.texinfo: Document `--locations' and `%locations'.
22226 * tests/calc.m4: Test it.
22228 For regularity of the names, replace each
22229 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
22230 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
22231 In addition replace each `flag' with `_flag'.
22233 2000-10-02 Akim Demaille <akim@epita.fr>
22235 Also test parse error messages, including with YYERROR_VERBOSE.
22237 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
22239 Use it to check the computations.
22240 Use it to check `nonassoc' is honored.
22241 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
22242 `--yyerror-verbose'.
22243 (_AT_CHECK_CALC): Adjust to this option.
22244 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
22246 2000-10-02 Akim Demaille <akim@epita.fr>
22248 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22249 the latter demonstrates a flaw in the handling of non debugging
22250 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22251 was used in order to simplify:
22267 unfortunately this leads to a CPP conflict when
22268 `--name-prefix=foo' is used since it produces `#define yydebug
22271 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
22272 (YYDPRINTF): New macro.
22274 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
22276 Also test `--verbose', `--defines' and `--name-prefix'.
22278 2000-10-02 Akim Demaille <akim@epita.fr>
22280 Improve the readability of the produced parsers.
22282 * src/bison.s1: Formatting changes.
22283 Improve the comment related to the `$' mark.
22284 (yydefault): Don't fall through to `yyresume': `goto' there.
22285 * src/output.c (output_parser): When the `$' is met, skip the end
22287 New variable, `number_of_dollar_signs', to check there's exactly
22288 one `$' in the parser skeleton.
22290 2000-10-02 Akim Demaille <akim@epita.fr>
22292 * lib/xstrdup.c: New file, from the fileutils.
22293 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
22294 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
22295 instead of strlen + xmalloc + strcpy.
22296 * src/symtab.c (copys): Remove, use xstrdup instead.
22298 2000-10-02 Akim Demaille <akim@epita.fr>
22300 * src/gram.h (associativity): New enum type which replaces the
22301 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
22302 `right_assoc', `left_assoc' and `non_assoc'.
22303 Adjust all dependencies.
22304 * src/reader.c: Formatting changes.
22305 (LTYPESTR): Don't define it, use it as a literal in
22306 `reader_output_yylsp'.
22307 * src/symtab.h (symbol_class): New enum type which replaces the
22308 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
22309 `sunknown', `stoken and `snterm'.
22311 2000-10-02 Akim Demaille <akim@epita.fr>
22313 * src/getargs.c (fixed_outfiles): Rename as...
22314 (yaccflag): for consistency and accuracy.
22315 Adjust dependencies.
22317 2000-10-02 Akim Demaille <akim@epita.fr>
22319 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22320 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22321 difficult and introduced a lot of core dump. It turns out that
22322 Bison used an implementation of `xmalloc' based on `calloc', and
22323 at various places it does depend upon the initialization to 0. I
22324 have not tried to isolate the pertinent places, and all the former
22325 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
22326 someone should address this issue.
22328 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
22329 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
22331 Adjust dependencies.
22332 * src/warshall.h: New file.
22335 2000-10-02 Akim Demaille <akim@epita.fr>
22337 Various anti-`extern in *.c' changes.
22339 * src/system.h: Include `assert.h'.
22341 2000-10-02 Akim Demaille <akim@epita.fr>
22343 * src/state.h (nstates, final_state, first_state, first_shift)
22344 (first_reduction): Move their exportation from here...
22345 * src/LR0.h: to here.
22346 Adjust dependencies.
22347 * src/getargs.c (statisticsflag): New variable.
22348 Add support for `--statistics'.
22349 Adjust dependencies.
22351 Remove a lot of now useless `extern' statements in most files.
22353 2000-10-02 Akim Demaille <akim@epita.fr>
22355 * src/LR0.h: New file.
22358 2000-10-02 Akim Demaille <akim@epita.fr>

22384 * src/reduce.h: New file.
22385 Propagate its inclusion.
22386 * src/reduce.c: Topological sort and other formatting changes.
22387 (bool, TRUE, FALSE): Move their definition to...
22388 * src/system.h: here.
22390 2000-10-02 Akim Demaille <akim@epita.fr>
22392 * src/files.c: Formatting changes.
22393 (tryopen, tryclose, openfiles): Rename as...
22394 (xfopen, xfclose, open_files): this.
22395 (stringappend): static.

22419 * src/lalr.c: Formatting changes, topological sorting etc.
22421 2000-10-02 Akim Demaille <akim@epita.fr>
22423 * src/output.c (token_actions): Introduce a temporary array,
22424 YYDEFACT, that makes it possible for this function to use
22425 output_short_table.
22427 2000-10-02 Akim Demaille <akim@epita.fr>
22429 `user_toknums' is output as a `short[]' in `output.c', while it is
22430 defined as a `int[]' in `reader.c'. For consistency with the
22431 other output tables, `user_toknums' is now defined as a table of
22434 * src/reader.c (user_toknums): Be a short table instead of an int
22436 Adjust dependencies.

22447 order to get rid of the `static' prototypes.
22448 No longer use `register'.

22450 Propagate its inclusion in files explicitly prototyping functions
22453 2000-09-21 Akim Demaille <akim@epita.fr>

22461 functions, use of closure.h.
22462 (initialize_closure, finalize_closure): Rename as...
22463 (new_closure, free_closure): these. Adjust dependencies.
22464 * src/LR0.c: Formatting changes, topological sort, use of
22466 (initialize_states): Rename as...
22467 (new_states): this.

22474 Don't define PARAMS.
22475 * src/system.h: Define PARAMS.
22476 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
22477 purpose of config.h. system.h must not try to fix wrong
22478 definitions in config.h.
22480 2000-09-20 Akim Demaille <akim@epita.fr>
22482 * src/derives.h: New file.

22607 * src/main.c (main): Register `done' to `atexit'.

22675 (copy_comment): Likewise.
22677 2000-03-17 Akim Demaille <akim@epita.fr>
22679 * src/reader.c (packsymbols): Formatting changes.

22694 2000-03-17 Akim Demaille <akim@epita.fr>
22696 Change the handling of @s so that they behave exactly like $s.
22697 There is now a pseudo variable @$ (readble and writable), location
22698 of the lhs of the rule (by default ranging from the location of
22699 the first symbol of the rhs, to the location of the last symbol,
22700 or, if the rhs is empty, YYLLOC).
22702 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
22704 (yyparse): When providing a default semantic action, provide a
22705 default location action.
22706 (after the $): No longer change `*YYLSP', just stack YYLOC the
22707 same way you stack YYVAL.
22708 * src/reader.c (read_declarations): Use warns.
22709 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
22710 (copy_action, case '@'): Likewise.
22711 Use a standard error message, to save useless work from
22714 2000-03-17 Akim Demaille <akim@epita.fr>

22732 2000-03-16 Akim Demaille <akim@epita.fr>
22734 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
22735 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
22736 One `#if YYDEBUG' remains, since it uses variables which are
22737 defined only if `YYDEBUG != 0'.
22739 2000-03-16 Akim Demaille <akim@epita.fr>
22741 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
22742 and related variables so that the similarities are highlighted.

23394 1995-10-15 Richard Stallman <rms@gnu.org>
23396 * src/vmsgetargs.c, src/getargs.c:
23397 Added -n, -k, and -raw switches.

23405 Revise error message.
23406 (print_notices): Remove final `.' from error message.
23408 * src/reader.c (reader_output_yylsp):
23410 (readgram): Use `#if 0' around code that accepted %command
23411 inside grammar rules: The documentation doesn't allow it,
23412 and it will fail since the %command processors scan for the next %.
23413 (parse_token_decl): Extended the %token
23414 declaration to allow a multi-character symbol as an alias.
23415 (parse_thong_decl): New function.
23416 (read_declarations): Added %thong declarations.
23417 (read_declarations): Handle NOOP to deal with allowing
23418 % declarations as another means to specify the flags.
23419 (readgram): Allow %prec prior to semantics embedded in a rule.
23420 (skip_to_char, read_declarations, copy_definition)
23421 (parse_token_decl, parse_start_decl, parse_type_decl)
23422 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
23423 (get_type_name, copy_guard, copy_action, readgram)
23424 (get_type, packsymbols): Revised most error messages.
23425 Changed `fatal' to `warnxxx' to avoid aborting for error.
23426 Revised and use multiple warnxxx functions to avoid using VARARGS1.
23427 (read_declarations): Improve the error message for
23428 an invalid character. Do not abort.
23429 (read_declarations, copy_guard, copy_action): Use
23430 printable_version to avoid unprintable characters in printed output.
23431 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
23432 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
23433 Allow the type of a non-terminal can be given
23434 more than once, as long as all specifications give the same type.
23437 (output_headers, output_trailers, output, output_gram)
23438 (output_rule_data): Implement noparserflag variable.
23439 Implement toknumflag variable.
23440 (output): Call reader_output_yylsp to output LTYPESTR.
23442 * src/main.c (main):
23443 If reader sees an error, don't process the grammar.
23444 (fatals): Updated to not use VARARGS1.
23445 (printable_version, int_to_string, warn, warni, warns, warnss)
23446 (warnsss): New error reporting functions. Avoid abort for error.
23449 Added THONG and NOOP for alias processing.
23450 Added SETOPT for the new code that allows setting options with %flags.
23453 Include getopt.h. Add some extern decls.
23454 (safegetc): New function to deal with EOF gracefully.
23455 (literalchar); new function to deal with reading \ escapes.
23456 (lex): Use literalchar.
23457 (lex): Implemented "..." tokens.
23458 (literalchar, lex, parse_percent_token): Made tokenbuffer
23459 always contain the token. This includes growing the token
23460 buffer while reading an integer.
23461 (parse_percent_token): Replaced if-else statement with percent_table.
23462 (parse_percent_token): Added % declarations as another
23463 way to specify the flags -n, -l, and -r. Also added hooks for
23464 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
23465 major changes to files.c.
23466 (lex) Retain in the incoming stream a character following
23468 (skip_white_space, lex): Revised most error messages
23469 and changed fatal to warn to avoid aborting.
23470 (percent_table): Added %thong declarations.
23472 * src/gram.h: Comment changes.
23474 * src/files.c (openfiles, open_extra_files, done):
23476 and actfile file. Handle noparserflag. Both for -n switch.
23478 * src/conflicts.c (resolve_sr_conflict):
23479 Remove use of alloca.
