528 * src/scan-gram.l (pure-parser): Return as a %<flag>.
530 2009-04-06 Joel E. Denny <jdenny@ces.clemson.edu>
532 Fix options documentation.
533 * build-aux/cross-options.pl: As in --help output, write optional
534 arguments as [=ARG] not =[ARG].
535 * doc/bison.texinfo (Bison Options): Add -W/--warnings argument.
537 2009-04-04 Joel E. Denny <jdenny@ces.clemson.edu>
539 Replace BISON_PROG_GNU_M4 with Autoconf's AC_PROG_GNU_M4.
540 If the first m4 in $PATH is wrong, it keeps looking. Moreover, its
541 requirements for a correct m4 are stricter.
542 * m4/m4.m4: Make it a symbolic link to submodules/autoconf/m4/m4.m4.
543 * configure.ac: Update to use AC_PROG_GNU_M4.
544 Reported by Eric Blake.
546 2009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>
548 Help with updating web manual.
549 * HACKING: Incorporate instructions from gnulib/doc/README.
550 * bootstrap.conf (gnulib_modules): Add gendocs.
552 2009-04-03 Akim Demaille <demaille@gostai.com>
555 * src/parse-gram.h, src/parse-gram.c: Regen.
557 2009-04-03 Akim Demaille <demaille@gostai.com>
559 Factor %FLAG at scan level.
560 * src/parse-gram.y (PERCENT_DEBUG, PERCENT_ERROR_VERBOSE): Token
561 definitions and associated rules, replaced by....
562 (PERCENT_FLAG): this new token type, and rule.
563 * src/scan-gram.l (RETURN_PERCENT_FLAG): New.
564 Use it for %debug and %error-verbose.

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

605 and discussed again starting at
606 <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
607 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
608 because location information is bogus.
609 Use angle brackets to delimit fake file name because square brackets
610 look like underexpanded m4. Choose a better fake file name.
611 Use negative line numbers.
612 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
613 * src/location.c (location_print): If line for a boundary is negative,
614 only print that boundary's file name.
615 * src/location.h: Document that.
616 * tests/skeletons.at (%define Boolean variables: invalid skeleton
617 defaults): Update output.
619 2009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>
621 Pacify ./configure --enable-gcc-warnings.
622 * Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS) because many files
623 in lib won't compile with it.
624 * src/local.mk (src_bison_CFLAGS): Use $(WERROR_CFLAGS) here only.
626 2009-03-31 Akim Demaille <demaille@gostai.com>
628 bootstrap: --help to stdout.
629 * bootstrap (usage): Don't send --help to stderr.

654 lalr1.cc: avoid GCC 4.3 warnings.
655 GCC 4.3 now warns about "a || b && c" and asks for explicit

658 * data/location.cc: Update copyright years.
659 (Position::operator==): Use parens to make precedence explicit.
660 Compare lines and columns first, as they are more likely to be
661 different, and they are faster to compare.
663 2009-03-26 Akim Demaille <demaille@gostai.com>
666 * gnulib: Update to latest.

682 2009-03-02 Akim Demaille <demaille@gostai.com>
684 Use locations in the variant example.
685 Yes, this obfuscates the point of this example, variants only.
686 But glr.cc cannot work (yet?) without locations. This change
687 makes it easier to use this example with glr.cc.
689 * examples/variant.yy (assert): %define it.
690 (locations): Request them.
691 (yylex): Bind the location to the stage.

707 b4_symbol_constructor_declare, as it is now done by
708 b4_public_types_define and b4_public_types_declare.
710 2009-03-02 Akim Demaille <demaille@gostai.com>

892 Propagate i18n changes into glr.c.
894 * data/glr.c (yyreportSyntaxError): Use "switch" instead of
895 building the error message format dynamically.
896 * data/lalr1.java: Formatting changes.
898 2008-12-11 Akim Demaille <demaille@gostai.com>
901 * tests/local.mk: Replace "cd && testsuite" by "testsuite -C".
902 Solves problems when top_srcdir is an absolute path.
903 Suggested by Eric Blake.
904 * configure.ac: Require Autoconf 2.62.
906 2008-12-11 Akim Demaille <demaille@gostai.com>
908 Simplify the i18n of the error messages.
909 * data/lalr1.cc: Comment changes.
910 * data/yacc.c (yysyntax_error): Rewrite, using a switch as in

915 Fix portability issue in the test suite.
916 * tests/local.at (AT_MATCHES_CHECK): New.
917 Based on Perl instead of Sed. Sed has too many portability
918 pitfalls, not ever Sed is GNU Sed.
919 * tests/actions.at (Fix user actions without a trailing semicolon):
922 2008-12-08 Akim Demaille <demaille@gostai.com>
925 * data/README: Document glr.cc, lalr1.java, m4sugar and xslt.

948 * tests/local.mk (tests/atconfig): The rule was incorrect, but
949 remove it: now that there is no tests/Makefile.am, the top-level
950 Makefile properly updates atconfig when needed.
952 2008-12-07 Di-an Jan <dianj@freeshell.org>
954 Implement the FIXME that ends an user action with a semicolon
955 if it seems necessary.
956 * src/scan-code.l (flex rules section): Flag cpp directive from
957 any `#' to the first unescaped end-of-line. Semicolon is not
958 needed after `;', `{', '}', or cpp directives and is needed after
959 any other token (whitespaces and comments have no effect).
960 * tests/actions.at (Fix user actions without a trailing semicolon):
962 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
963 to make user actions complete statements.
964 Adjust column numbers in error messages.

971 * gnulib: Update from master.
973 2008-12-05 Eric Blake <ebb9@byu.net>
975 Avoid compiler warning.
976 * src/output.c (muscle_insert_item_number_table): Delete unused
979 2008-12-02 Eric Blake <ebb9@byu.net>
981 Build testsuite with newer autoconf.
982 * tests/output.at (m4_expand): Don't override in newer autoconf,
983 where the underlying implementation changed.
984 * tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
985 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
986 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
987 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
988 since some of them contain unbalanced ')'.
990 2008-12-01 Akim Demaille <demaille@gostai.com>
992 Use b4_symbol for printers and destructors everywhere.
993 * data/bison.m4 (b4_symbol_action_location): New.
994 * data/c.m4 (b4_symbol_actions): Remove.
995 Adjust all callers to use by b4_symbol_foreach and the corresponding
996 b4_symbol_printer/destructor macro.
997 * data/glr.cc: Adjust.
998 * data/lalr1.java: Adjust the %destructor sanity check.
999 * src/output.c (symbol_code_props_output): Remove, we no longer
1000 need the b4_symbol_printers/destructors tables.
1002 2008-12-01 Akim Demaille <demaille@gostai.com>
1004 Use b4_symbol_case_.
1005 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
1008 2008-12-01 Akim Demaille <demaille@gostai.com>
1010 Move b4_symbol based macro to bison.m4.
1011 * data/lalr1.cc (b4_symbol_, b4_symbol, b4_symbol_if)
1012 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
1013 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
1014 (b4_type_foreach): Move to...
1015 * data/bison.m4: Here.
1016 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
1017 b4_symbol_value_template instead of b4_symbol_value.
1019 2008-12-01 Akim Demaille <demaille@gostai.com>
1021 b4_symbol/type_foreach.
1022 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
1025 2008-12-01 Akim Demaille <demaille@gostai.com>
1027 Use the symbol properties to output the printer/destructor for lalr1.cc.
1028 Instead of defining complex list of tuples to define various
1029 properties of the symbols, we now prefer to define symbols as
1030 "structs" in m4: using the symbol key (its number), and the
1031 property name, b4_symbol gives it value. Use this to handle
1032 destructors and printers.
1034 * src/output.c (CODE_PROP): New.
1035 (prepare_symbol_definitions): Use it to define the printer and
1036 destructor related attributes of the symbols.
1037 * data/lalr1.cc (b4_symbol_actions): Rename as...
1038 (b4_symbol_action): this.
1039 Use b4_symbol instead of 6 arguments.
1040 (b4_symbol_printer, b4_symbol_destructor): New.
1041 Use them instead of b4_symbol_actions.
1043 2008-12-01 Akim Demaille <demaille@gostai.com>
1045 Avoid capturing variables too easily.
1046 * src/muscle_tab.h (MUSCLE_INSERT_BOOL, MUSCLE_OBSTACK_SGROW): Use
1047 v__ and p__ instead of v and p.
1049 2008-12-01 Akim Demaille <demaille@gostai.com>
1051 Remove spurious empty line before syncline.
1052 * data/bison.m4 (b4_syncline): Don't output an empty line before
1055 2008-11-26 Akim Demaille <demaille@gostai.com>
1057 Convert lib/Makefile.am into lib/local.mk.
1058 The real problem is rather gnulib.mk, which itself is extracted
1059 from a Makefile.am that gnulib expects to the "recursive". The
1060 tool prefix-gnulib-mk converts such a gnulib.mk to be
1061 non-recursive. Also, some AC_SUBST variables need to be adjusted.
1063 * etc/prefix-gnulib-mk: New.
1064 * bootstrap (slurp): Use it to convert further gnulib.mk.
1065 No longer try to avoid re-creation of lib/gnulib.mk as the changes
1067 * lib/Makefile.am: Rename as...

1132 the order of the tables changed.
1134 2008-11-26 Akim Demaille <demaille@gostai.com>
1136 Get rid of (yy)rhs and (yy)prhs.
1137 These tables are no longer needed in the parsers, and they don't seem to
1138 be useful. They are not documented either.
1140 * src/output.c (prepare_rules): Get rid of rhs and prhs.
1141 Adjust the computation of (yy)r2.
1143 2008-11-26 Akim Demaille <demaille@gostai.com>

1173 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
1174 as an Autotest keyword.

1195 2008-11-25 Akim Demaille <demaille@gostai.com>
1197 Get rid of yyrhs and yyprhs in yacc.c.
1198 They were used to get the symbol types, given a rule number, when
1199 displaying the top of the stack before a reduction. But the
1200 symbol type is available from the state stack. This has two be
1201 benefits: two tables less in the parser (making it smaller), and a
1202 more consistent use of the three stacks which will help to fuse
1205 * data/yacc.c (yyprhs, yyrhs): Remove.
1206 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
1207 (yy_reduce_print): Take yyssp as argument.
1208 Use it, together with yystos, to get the symbol type.

1396 2008-11-15 Akim Demaille <demaille@gostai.com>
1398 Support parametric types.
1400 There are two issues to handle: first scanning nested angle
1401 bracket pairs to support types such as std::pair< std::string,
1402 std::list<std::string> > >.
1404 Another issue is to address idiosyncracies of C++: do not glue two
1405 closing angle brackets together (otherwise it's operator>>), and
1406 avoid sticking blindly a TYPE to the opening <, as it can result
1407 in '<:' which is a digraph for '['.
1409 * src/scan-gram.l (brace_level): Rename as...
1412 Implement support for complex tags.

1426 This is not sufficient, but we test at least that the make_SYMBOL
1427 interface is not affected by token.prefix. A more general test
1428 will be implemented when the support of token.prefix is generalized

1505 Move sc_tight_scope into maint.mk.
1506 It does not work, and I don't know how it was supposed to work: it

1508 it at a better place, fixing it is still required.

1533 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on

1595 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
1597 Using template buys us nothing, and makes it uselessly complex to
1598 construct a symbol. Besides, it could not be generalized to other
1599 languages, while make_FOO would work in C/Java etc.

1602 (b4_symbol): Use it.
1603 (b4_symbol_constructor_declaration_)
1604 (b4_symbol_constructor_definition_): Instead of generating
1605 specializations of an overloaded template function, just generate
1606 several functions whose names are forged from the token names
1607 without the token.prefix.
1608 (b4_symbol_constructor_declarations): Generate them for all the
1609 symbols, not just by class of symbol type, now that instead of
1610 specializing a function template by the token, we generate a
1611 function named after the token.
1612 (b4_symbol_constructor_specialization_)

1619 Provide a means to add a prefix to the name of the tokens as
1620 output in the generated files. Because of name clashes, it is
1621 good to have such a prefix such as TOK_ that protects from names
1622 such as EOF, FILE etc. But it clutters the grammar itself.
1624 * data/bison.m4 (token.prefix): Empty by default.
1625 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
1626 * data/lalr1.cc (b4_symbol): Ditto.
1628 2008-11-13 Akim Demaille <demaille@gostai.com>
1630 Compute at M4 time some of the subtractions.
1631 * data/lalr1.cc (b4_subtract): New.
1632 (b4_rhs_data): Use it.
1634 2008-11-13 Akim Demaille <demaille@gostai.com>
1637 This allows the user to get the type of a token returned by yylex.
1639 * data/lalr1.cc (symbol::token): New.
1640 (yytoknum_): Define when %define lex_symbol, independently of
1642 (yytoken_number_): Move into...
1643 (symbol::token): here, since that's the only use.
1644 The other one is YYPRINT which was not officially supported
1645 by lalr1.cc, and anyway it did not work since YYPRINT uses this
1646 array under a different name (yytoknum).
1648 2008-11-13 Akim Demaille <demaille@gostai.com>
1651 * TODO (YYERRCODE): Mention the case of $undef.
1653 2008-11-13 Akim Demaille <demaille@gostai.com>
1656 * TODO (YYPRINT): New.
1658 2008-11-13 Akim Demaille <demaille@gostai.com>
1661 * data/lalr1.cc, data/yacc.c: Fix the description of the
1662 yytranslate and yytoknum tables.
1664 2008-11-13 Akim Demaille <demaille@gostai.com>
1666 Define make_symbol in the header.
1667 To reach good performances these functions should be inlined (yet
1668 this is to measure precisely). To this end they must be available
1671 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
1672 location_type with the class name.
1673 Since will now be output in the header, declare "inline".
1674 No longer use b4_symbol_constructor_specializations, but
1675 b4_symbol_constructor_definitions in the header.
1676 Don't call it in the *.cc file.
1678 2008-11-13 Akim Demaille <demaille@gostai.com>
1680 Define yytranslate in the header for lex_symbol.
1681 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
1682 into the header file when using %define lex_symbol.
1683 (yytranslate_): Declare inline.
1685 2008-11-13 Akim Demaille <demaille@gostai.com>
1687 Define the constructors of symbol_type in
1688 b4_symbol_constructor_definitions.
1689 The constructors are called by the make_symbol functions, which a
1690 forthcoming patch will move elsewhere. Hence the interest of
1691 putting them together.
1693 The stack_symbol_type does not need to be moved, it is used only
1696 * data/lalr1.cc: Move symbol_type and symbol_base_type
1697 constructors into...
1698 (b4_symbol_constructor_definitions): here.
1701 2008-11-13 Akim Demaille <demaille@gostai.com>
1703 Make it easier to move the definition of yytranslate_.
1704 Forthcoming changes will make it possible to use yytranslate_
1705 from outside the parser implementation file.
1707 * data/lalr1.cc (b4_yytranslate_definition): New.
1710 2008-11-13 Akim Demaille <demaille@gostai.com>
1712 Remove useless class specification.
1713 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
1714 to refer to the class name to use a type defined by the class for
1715 arguments of member functions.
1717 2008-11-13 Akim Demaille <demaille@gostai.com>
1719 Finer input type for yytranslate.
1720 This patch is debatable: the tradition expects yylex to return an int
1721 which happens to correspond to token_number (which is an enum). This
1722 allows for instance to return characters (such as '*' etc.). But this
1723 goes against the stronger typing I am trying to have with the new
1724 lex interface which return a symbol_type. So in this case, feed
1725 yytranslate_ with a token_type.
1727 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
1728 expect a token_type.
1730 2008-11-13 Akim Demaille <demaille@gostai.com>
1732 Honor lex-params in %define lex_symbol mode.
1733 * data/lalr1.cc: Use b4_lex_param.
1735 2008-11-13 Akim Demaille <demaille@gostai.com>
1738 * src/output.c (symbol_definitions_output): Rename symbol
1739 attributes type_name and has_type_name as type and has_type.
1740 * data/lalr1.cc: Adjust uses.
1742 2008-11-13 Akim Demaille <demaille@gostai.com>
1744 Use b4_type_names for the union type.
1745 The union used to compute the size of the variant used to iterate
1746 over the type of all the symbols, with a lot of redundancy. Now
1747 iterate over the lists of symbols having the same type-name.
1749 * data/lalr1.cc (b4_char_sizeof_): New.
1750 (b4_char_sizeof): Use it.
1751 Adjust to be called with a list of numbers instead of a single
1753 Adjust its caller for new-line issues.
1755 2008-11-13 Akim Demaille <demaille@gostai.com>
1757 Define the "identifier" of a symbol.
1758 Symbols may have several string representations, for instance if
1759 they have an alias. What I call its "id" is a string that can be
1760 used as an identifier. May not exist.
1762 Currently the symbols which have the "tag_is_id" flag set are
1763 those that don't have an alias. Look harder for the id.
1765 * src/output.c (is_identifier): Move to...
1766 * src/symtab.c (is_identifier): here.
1767 * src/symtab.h, src/symtab.c (symbol_id_get): New.
1768 * src/output.c (symbol_definitions_output): Use it to define "id"
1770 Remove the definition of "tag_is_id".
1771 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
1772 "tag_is_id" were used to produce code.
1773 We still use "tag" for documentation.
1775 2008-11-11 Akim Demaille <demaille@gostai.com>
1777 Locations are no longer required by lalr1.cc.
1778 * data/lalr1.cc (_b4_args, b4_args): New.
1779 Adjust all uses of locations to make them optional.
1780 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
1781 (AT_CHECK_NAMESPACE): Check the use of locations.
1782 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
1783 without locations with lalr1.cc.
1785 * tests/output.at: Check lalr1.cc with and without location
1787 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
1788 Don't use locations.
1790 2008-11-11 Akim Demaille <demaille@gostai.com>
1793 * tests/local.at (AT_FULL_COMPILE): New.
1794 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
1796 2008-11-11 Akim Demaille <demaille@gostai.com>
1798 Support parens in calc++.
1799 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
1800 * examples/calc++/test (run): Check the expected output.
1804 2008-11-11 Akim Demaille <demaille@gostai.com>
1806 Simplify lalr1.cc since %defines is mandatory.
1807 * data/lalr1.cc: Remove useless calls to b4_defines_if.
1809 2008-11-11 Akim Demaille <demaille@gostai.com>
1812 * TODO (yysyntax_error): New item.
1814 2008-11-11 Akim Demaille <demaille@gostai.com>
1817 * data/lalr1.cc: Use b4_error_verbose_if instead of #if
1820 2008-11-11 Akim Demaille <demaille@gostai.com>
1822 Support i18n of the parse error messages.
1823 * TODO (lalr1.cc/I18n): Remove.
1824 * data/lalr1.cc (yysyntax_error_): Support the translation of the
1825 error messages, as done in yacc.c.
1826 Stay within the yy* pseudo namespace.
1828 2008-11-11 Akim Demaille <demaille@gostai.com>
1831 * TODO (single stack, yysyntax_error): New.
1833 2008-11-11 Akim Demaille <demaille@gostai.com>
1835 Make it possible to return a symbol_type from yylex.
1836 * data/lalr1.cc (b4_lex_symbol_if): New.
1837 (parse): When lex_symbol is defined, expected yylex to return the
1839 * etc/bench.pl.in (generate_grammar_list): Extend to support this
1841 (bench_variant_parser): Exercise it.
1843 2008-11-11 Akim Demaille <demaille@gostai.com>
1845 Remove useless bench case.
1846 * etc/bench.pl.in (bench_variant_parser): VARIANT_DESTROY is
1849 2008-11-11 Akim Demaille <demaille@gostai.com>
1851 Improve display of directives.
1852 * etc/bench.pl.in (parse_term): Don't add useless eol.
1854 2008-11-11 Akim Demaille <demaille@gostai.com>
1856 Use string_cast in the bench.
1857 * etc/bench.pl.in (generate_grammar_list): Define and use
1860 2008-11-11 Akim Demaille <demaille@gostai.com>
1862 Replace yychar with a Boolean.
1863 * data/lalr1.cc (parse::yychar): Replace by...
1864 (parse::yyempty): this.
1866 2008-11-11 Akim Demaille <demaille@gostai.com>
1871 2008-11-11 Akim Demaille <demaille@gostai.com>
1873 Let yytranslate handle the eof case.
1874 * data/lalr1.cc (yytranslate_): Handle the EOF case.
1876 No longer expect yychar to be equal to yyeof_, rather, test the
1877 lookahead's (translated) kind.
1879 2008-11-11 Akim Demaille <demaille@gostai.com>
1881 yychar cannot be empty in yyerrlab.
1882 * TODO (yychar == yyempty_): New.
1883 * data/lalr1.cc: Remove the handling of this case.
1884 This eases forthcoming changes related to yychar and yytranslate.
1886 2008-11-11 Akim Demaille <demaille@gostai.com>
1888 Bench: syntactic sugar for %define/#define.
1889 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
1890 (&bench_push_parser, bench_variant_parser): Use this feature.
1894 2008-11-11 Akim Demaille <demaille@gostai.com>
1896 Less memory pressure on the "list" bench.
1897 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
1898 the values, to limit memory pressure.
1900 2008-11-11 Akim Demaille <demaille@gostai.com>
1902 Introduce make_symbol.
1903 make_symbol provides a means to construct a full symbol (kind,
1904 value, location) in a single shot. It is meant to be a Symbol
1905 constructor, parameterized by the symbol kind so that overloading
1906 would prevent incorrect kind/value pairs. Unfortunately
1907 parameterized constructors do not work well in C++ (unless the
1908 parameter also appears as an argument, which is not acceptable),
1909 hence the use of a function instead of a constructor.
1911 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1912 (b4_symbol_constructor_declarations)
1913 (b4_symbol_constructor_specialization_)
1914 (b4_symbol_constructor_specializations)
1915 (b4_symbol_constructor_definition_)
1916 (b4_symbol_constructor_definitions): New.
1917 Use them where appropriate to generate declaration, declaration of
1918 the specializations, and implementations of the templated
1919 overloaded function "make_symbol".
1920 (variant::variant): Always define a default ctor.
1921 Also provide a copy ctor.
1922 (symbol_base_type, symbol_type): New ctor overloads for value-less
1924 (symbol_type): Now public, so that functions such as yylex can use
1927 2008-11-11 Akim Demaille <demaille@gostai.com>
1929 Inform m4 whether a tag is a valid id.
1930 * src/output.c (is_identifier): New.
1931 (symbol_definitions_output): Use it to define tag_is_id.
1932 But maybe this should be done at m4 level?
1934 2008-11-11 Akim Demaille <demaille@gostai.com>
1936 Test 214 was failing: it greps with a pattern containing [ ]*
1937 which obviously meant to catch spaces and tabs, but contained only
1938 spaces. Tabulations in sources are a nuisance, so to simplify the
1939 matter, get rid of all the tabulations in the Java sources. The
1940 other skeletons will be treated equally later.
1942 * data/java.m4, data/lalr1.java: Untabify.
1943 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1944 tabulations are no longer generated.
1946 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
1948 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
1949 * configure.ac: Adjust usage.
1950 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1951 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1952 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).

1956 Workaround Java's ``code too large'' problem for parser tables
1957 in most cases, by using one function per initialization.
1958 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
1959 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
1960 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_
1961 yyprhs_, yyrline_, yytranslate_table_): Use b4_integral_parser_table.

1968 * NEWS: Document them.
1970 General Java skeleton improvements.
1971 * configure.ac (gt_JAVACOMP): Request target of 1.4, which allows
1972 using gcj < 4.3 in the testsuite, according to comments in
1973 gnulib/m4/javacomp.m4.
1974 * data/java.m4 (stype, parser_class_name, lex_throws, throws,
1975 location_type, position_type): Remove extraneous brackets from
1976 b4_percent_define_default.
1977 (b4_lex_param, b4_parse_param): Remove extraneous brackets from
1978 m4_define and m4_define_default.
1979 * data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
1980 which marks the end of user code with appropriate syncline, like all
1981 the other skeletons.
1982 (b4_user_post_prologue): Add. Don't silently drop.
1984 (parse): Inline yylex.
1985 * doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
1986 (%{...%}): Fix typo of %code imports.
1987 * tests/java.at (AT_JAVA_COMPILE): Add "java" keyword.
1989 Support annotations on parser class with %define annotations.

1991 * doc/bison.texinfo (Java Parser Interface): Document
1992 %define annotations.

2003 about %error-verbose having no effect.
2004 (getErrorVerbose, setErrorVerbose): Document.
2006 Move constants for token names to Lexer interface.
2007 * data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.
2008 * data/java.m4 (b4_token_enum): Indent for move to Lexer interface.
2009 (parse): Qualify EOF to Lexer.EOF.
2010 * doc/bison.texinfo (Java Parser Interface): Move documentation of
2011 EOF and token names to Java Lexer Interface.
2012 * tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove Calc qualifier.
2014 Make yyerror public.
2015 * data/lalr1.java (Lexer.yyerror): Use longer parameter name.
2016 (yyerror): Change to public. Add Javadoc comments. Use longer
2017 parameter names. Make the body rather than the declarator
2018 conditional on %locations.
2019 * doc/bison.texinfo (yyerror): Document. Don't mark as protected.
2021 Allow user to add code to the constructor with %code init.

2049 including those that don't have a type-name.
2050 (symbol_definitions_output): Define "is_token" and
2052 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
2053 type-name, now that they are defined too in b4_type_names.

2059 2008-11-10 Akim Demaille <demaille@gostai.com>
2061 Make parser::yytranslate static.
2062 Small speedup (1%) on the list grammar. And makes yytranslate_
2063 available in non member functions.

2070 Avoid trailing spaces.
2071 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
2072 * data/lalr1.cc: Don't indent before rule and symbol actions, as
2073 they can be empty, and anyway this incorrectly indents the first

2080 2008-11-10 Akim Demaille <demaille@gostai.com>
2082 Use "enum" for integral constants.
2083 This is just nicer to read, I observed no speedup.
2085 * data/lalr1.cc (yyeof_, yylast_, yynnts_, yyempty_, yyfinal_)
2086 (yterror_, yyerrcode_, yyntokens_): Define as members of an enum.

2122 2008-11-10 Akim Demaille <demaille@gostai.com>
2124 Change the handling of the symbols in the skeletons.
2125 Before we were using tables which lines were the symbols and which
2126 columns were things like number, tag, type-name etc. It is was
2127 difficult to extend: each time a column was added, all the numbers had
2128 to be updated (you asked for colon $2, not for "tag"). Also, it was
2129 hard to filter these tables when only a subset of the symbols (say the
2130 tokens, or the nterms, or the tokens that have and external number
2131 *and* a type-name) was of interest.
2133 Now instead of monolithic tables, we define one macro per cell. For
2134 instance "b4_symbol(0, tag)" is a macro name which contents is
2135 self-decriptive. The macro "b4_symbol" provides easier access to
2138 * src/output.c (type_names_output): Remove.
2139 (symbol_numbers_output, symbol_definitions_output): New.
2140 (muscles_output): Call them.
2141 (prepare_symbols): Define b4_symbols_number.

2146 * src/getargs.h, src/getargs.c (trace_muscle): New.
2147 (trace_types, trace_args): Support it.

2150 2008-11-10 Akim Demaille <demaille@gostai.com>

2182 2008-11-10 Akim Demaille <demaille@gostai.com>
2184 Add %precedence support.
2185 Unfortunately it is not possible to reuse the %prec directive. This
2186 is because to please POSIX, we do not require to end the rules with a
2187 semicolon. As a result,
2191 is ambiguous: either a rule which precedence is that of baz, or a rule,
2192 and then a declaration of the precedence of the token baz.

2320 2008-11-09 Akim Demaille <demaille@gostai.com>
2322 Rely on the state stack to display reduction traces.
2323 To display rhs symbols before a reduction, we used information
2324 about the rule reduced, which required the tables yyrhs and
2325 yyprhs. Now use rely only on the state stack to get the same

2452 2008-11-07 Akim Demaille <demaille@gostai.com>
2454 Add "%define assert" to variants.
2455 This is used to help the user catch cases where some value gets
2456 ovewritten by a new one. This should not happen, as this will
2459 Unfortunately this uncovered a bug in the C++ parser itself: the
2460 lookahead value was not destroyed between two calls to yylex. For
2461 instance if the previous lookahead was a std::string, and then an int,
2462 then the value of the std::string was correctly taken (i.e., the
2463 lookahead was now an empty string), but std::string structure itself
2466 This is now done in variant::build(other&) (which is used to take the
2467 value of the lookahead): other is not only stolen from its value, it
2468 is also destroyed. This incurs a new performance penalty of a few
2469 percent, and union becomes faster again.
2471 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

2750 Fuse the three stacks into a single one.
2752 In order to make it easy to perform benchmarks to ensure that
2753 there are no performance loss, lalr1.cc is forked into
2754 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2757 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2758 exercized by the test suite, the user must install a symbolic link
2759 from lalr1.cc to it.
2761 Instead of having three stacks (state, value, location), use a
2762 stack of triples. This considerably simplifies the code (and it
2763 will be easier not to require locations as currently does the C++
2764 parser), and also gives a 10% speedup according to
2765 etc/bench (probably mainly since memory allocation is done once
2766 instead of three times).
2768 Another motivation is to make it easier to destruct properly
2769 semantic values: now that they are bound to their state (hence
2770 symbol type) it will be easier to call the appropriate destructor.
2772 These changes should probably benefit the C parser too.
2774 * data/lalr1.cc: Copy as...
2775 * data/lalr1-fusion.cc: this new file.
2776 (b4_rhs_value, b4_rhs_location): New definitions overriding those
2778 (state_stack_type, semantic_stack_type, location_stack_type)
2779 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
2780 (data_type, stack_type, yystack_): New.
2781 (YYLLOC_DEFAULT, yypush_): Adjust.
2782 (yyerror_range): Now based on data_type, not location_type.
2784 2008-11-03 Akim Demaille <demaille@gostai.com>
2786 Push the state, value, and location at the same time.
2787 This is needed to prepare a forthcoming patch that fuses the three
2790 * data/lalr1.cc (parser::yypush_): New.
2791 (parser::yynewstate): Change the semantics: instead of arriving to
2792 this label when value and location have been pushed, but yystate
2793 is to be pushed on the state stack, now the three of them must
2794 have been pushed before. yystate still must be the new state.
2795 This allows to use yypush_ everywhere instead of individual
2796 handling of the stacks.
2798 2008-11-03 Akim Demaille <demaille@gostai.com>
2800 Prefer references to pointers.
2801 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
2802 definition to use references instead of pointers.
2803 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
2804 Take the value and location as references.
2807 2008-11-03 Akim Demaille <demaille@gostai.com>
2809 stack::size instead of stack::height.
2810 * data/lalr1.cc (stack::height): Rename as...
2811 (stack::size): this.
2812 Fix the output type.
2815 2008-11-03 Akim Demaille <demaille@gostai.com>
2817 Use variants to support objects as semantic values.
2818 This patch was inspired by work by Michiel De Wilde. But he used
2819 Boost variants which (i) requires Boost on the user side, (ii) is
2820 slow, and (iii) has useless overhead (the parser knows the type of
2821 the semantic value there is no reason to duplicate this
2822 information as Boost.Variants do).
2824 This implementation reserves a buffer large enough to store the
2825 largest objects. yy::variant implements this buffer. It was
2826 implemented with Quentin Hocquet.
2828 * src/output.c (type_names_output): New.
2829 (output_skeleton): Invoke it.
2830 * data/c++.m4 (b4_variant_if): New.
2831 (b4_symbol_value): If needed, provide a definition for variants.
2832 * data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
2833 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
2834 (b4_char_sizeof, yy::variant): New.
2835 (parser::parse): If variants are requested, define
2836 parser::union_type, parser::variant, change the definition of
2837 semantic_type, construct $$ before running the user action instead
2838 of performing a default $$ = $1.
2839 * examples/variant.yy: New.
2840 Based on an example by Michiel De Wilde.
2842 2008-11-03 Akim Demaille <demaille@gostai.com>
2844 Parameterize the extraction of semantic values.
2845 To make future changes easier, no longer rely on ".TYPE" being the
2846 way to get a semantic value.
2848 * data/c.m4 (b4_symbol_value): New.
2850 * data/c++.m4, data/yacc.c: Use it.
2851 * data/glr.c: Use b4_symbol_value.
2855 2008-11-03 Akim Demaille <demaille@gostai.com>
2857 Prepare easier M4 changes.

2878 2008-11-02 Joel E. Denny <jdenny@ces.clemson.edu>
2880 Say %language is experimental.
2881 We're thinking of extending it's effect on output file naming. See the

2959 Always put auxiliary code files in the same dir as other output files.
2960 * src/files.c (compute_file_name_parts): When the user specifies
2961 --output but not --file-prefix, extract the directory prefix from the
2962 file prefix not from the grammar file name. This affects the location
2963 of files like location.hh generated by the C++ skeleton. The includes

3200 Fix dependence on computed configure variables.
3201 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not

3226 (EXTRA_DIST): Remove GNUmakefile, handled by Gnulib. Add maint.mk,
3227 .prev-version, and .version.
3228 * NEWS (2.3b+): Rename to...
3229 (?.?): ... this because we're dropping the "+" version naming scheme,
3230 but, in general, we still can't be sure of our next release name.
3231 * bootstrap: Add a quick hack to remove from .gitignore the
3232 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
3233 entry. This should really be fixed in gnulib instead.

3267 * bootstrap (insert_sorted_if_absent): Replace all uses with...
3268 (insert_vc_ignore): ... this new function, which prepends `/' to all
3269 .gitignore entries before passing them to insert_sorted_if_absent.
3270 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
3271 .cvsignore files are maintained even though Bison developers run
3272 bootstrap while using Git.
3273 * .cvsignore (*.patch *.log log patches applied): Remove, apparently

3381 Update to the current gnulib CVS repository, and fix trigraph handling
3383 * bootstrap: Update gnulib CVS repository URL.
3384 (symlink_to_dir): Encapsulate the code that guarantees the destination
3385 directory exists into...
3386 (check_dst_dir): ... this new function, and...
3387 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
3388 fail when copying files into lib/uniwidth/.
3389 * src/output.c (prepare_symbols): When writing yytname muscles, where
3390 symbol names will be encoded in C-string literals, tell quotearg to
3391 escape trigraphs. This used to be the default in gnulib.
3392 * tests/regression.at (Token definitions): Because of the change in
3393 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
3394 escapes trigraphs in symbol names. Thus, yytname no longer has
3395 trigraphs unnecessarily doubly escaped. Update test case output.
3396 Extend test case to be sure Bison's own error messages will no longer
3397 have trigraphs in symbol names unnecessarily escaped once.

3415 * src/getargs.c (usage): Explain the relationship between arguments of
3416 long and short options more completely. Document --defines and -d
3417 separately since the former takes an argument but, for POSIX Yacc, the
3419 (short_options): Let -W take an optional argument like --warnings.

4156 2007-09-25 Joel E. Denny <jdenny@ces.clemson.edu>
4158 Replace `%push-parser' and `%push-pull-parser' with
4159 `%define push_pull "push"' and `%define push_pull "both"'.
4160 `%define push_pull "pull"' is the default.

4162 Pull Parser Function, Parser Create Function, Parser Delete Function):
4163 Update declarations.
4164 (Decl Summary, Table of Symbols): Replace %push-parser and

4169 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
4171 * data/push.c: ... to here and compute them from the value of the
4172 %define variable push_pull.
4173 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
4174 parsing requests here...
4175 * data/yacc.c: ... hack this to switch to push.c any time
4176 b4_use_push_pull_flag or the %define variable push_pull is set. This
4177 will go away when we mv push.c yacc.c.
4178 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
4179 push parsing is not supported since unused %define variables are
4181 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.

4214 Problem reported by Wojciech Polak.
4215 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.
4216 (xml_printf): Undo change I made on 21 September; that is,
4217 indent 2 spaces, not 1.
4219 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
4221 Pacify ./configure --enable-gcc-warnings.
4222 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
4223 `char const *' instead of `char *'.
4224 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
4225 local variable `sep'.
4227 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
4229 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
4231 * src/print-xml.c: Prefer "const" after types; that's more consistent.
4232 (xml_printf): Indent just 1 space for level.
4233 (e_char, xlate_char): Remove.
4234 (xml_escape_string): Rewrite to avoid undefined behavior (used
4235 storage that was freed from the stack).
4236 (xml_escape_n): Don't bother checking for subscript error.
4238 2007-09-21 Wojciech Polak <polak@gnu.org>

4283 * README-hacking: Likewise.
4287 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
4288 Bruno Haible <bruno@clisp.org>
4290 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
4291 and is a script that invokes bison. Tighten the code. Add comments.
4293 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

4300 * tests/skeletons.at (%define boolean variables: invalid skeleton
4301 defaults): Rename to...
4302 (%define Boolean variables: invalid skeleton defaults): ... this and
4305 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
4307 In impure push mode, don't allow more than one yypstate to be allocated
4308 since multiple impure parsers would corrupt yynerrs.
4309 * data/push.c (yypstate_allocated): New static global variable
4311 (yypull_parse): If yypstate_new returns 0, don't report it as memory
4312 exhaustion if yypstate_allocated is 1, but still return 2.
4313 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
4314 already 1. Otherwise, set it to 1.
4315 (yypstate_delete): Set it to 0.
4316 * tests/push.at (Push Parsing: Multiple impure instances): New test

4390 Get rid of broken %no-parser, -n, and --no-parser implementation and
4392 * TODO: Don't mention them.
4393 * doc/bison.1: Likewise.
4394 * doc/bison.texinfo (Decl Summary): Likewise.
4395 (Bison Options): Likewise.
4396 (Option Cross Key): Likewise.
4397 * src/getargs.c (no_parser_flag): Remove global variable.
4398 (usage): Don't print description of -n and --no-parser.
4399 (long_options): Remove --no-parser entry here.
4400 (getargs): Remove -n case in the switch here.
4401 * src/getargs.h (no_parser_flag): Remove extern.
4402 * tests/regression.at (Web2c Actions): Remove comment that mentions
4405 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
4407 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
4408 name user variables starting with `yy'. Just pass NULL instead of a
4409 dummy local &yylval to yypush_parse.
4410 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
4413 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
4415 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
4416 true since it's then always used regardless of whether yyoverflow is
4417 defined. Reported by Christian Burger at
4418 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
4419 * THANKS: Add Christian Burger.
4421 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4422 node names: say "Decl Summary" not "Bison Declaration Summary".
4424 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
4426 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
4427 determine whether this function has already complained about an invalid
4428 value for a %define boolean variable, don't check whether Bison has
4429 ever examined the value. As written, the check was a tautology.
4430 Instead, record and check for this complaint using a separate muscle.
4432 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
4434 Fix push parsing memory leak reported by Brandon Lucia at
4435 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
4436 * THANKS: Add Brandon Lucia.
4437 * data/push.c (yypstate_delete): Free the stack if it was reallocated
4438 but the parse never completed and thus freed it.
4439 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
4440 * tests/testsuite.at: Include push.at.
4441 * test/push.at: New.
4442 (Push Parsing: Memory Leak for Early Deletion): New test case.
4444 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
4446 Improve handling of multiple S/R conflicts in the same state and of S/R
4447 conflicts involving multiple reductions.
4448 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
4449 set for a state here or Bison will abort if it is reassigned on a
4450 later conflicted reduction in the same state.
4451 Similarly, don't finalize and assign the solved conflicts report here
4452 or it will be lost if it is reassigned on a later conflicted reduction
4454 (set_conflicts): Instead, assign them both here after all S/R conflicts
4455 in the state have been fully examined.
4456 * src/print.c (shift_set): Rename to...
4457 (no_reduce_set): ... this.
4458 (print_reductions): Update for rename, and add %nonassoc error action
4459 tokens to no_reduce_set so that, when printing the first remaining
4460 reduction on an error action token, the reduction is enclosed in
4462 (print_results): Update for rename.
4463 * tests/conflicts.at (Solved conflicts report for multiple reductions
4464 in a state): New test case.
4465 (%nonassoc error actions for multiple reductions in a state): New test
4468 * src/main.c (main): Don't depend on C99 features.
4470 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
4472 * build-aux/.cvsignore: Add compile.
4473 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
4476 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
4478 * bootstrap (slurp): Create target directories that don't exist.
4479 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
4481 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4483 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
4485 * closure.c (closure): Likewise.
4486 * state.h (reductions): Comment sorting of rules.
4487 (state): Comment sorting of items.
4489 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
4491 Fix C++ test cases after recent Gnulib changes. Discussed starting at
4492 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
4493 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
4494 definition in order to avoid Gnulib headers since we don't use config.h
4496 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
4497 rather than AT_DATA so that config.h is included.
4499 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
4501 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
4502 instead of fprintf. Guard these functions with #if YYDEBUG instead of
4503 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
4504 and so that YYFPRINTF is guaranteed to be defined here.
4506 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4508 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
4510 (muscle_percent_define_check_values): ... this more helpful function.
4511 Again, it's not used yet, but it will be.
4512 * src/muscle_tab.h: Likewise.
4514 Improve some comments in parser table construction.
4515 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
4516 (generate_states): Don't mention ruleset, which is internal to closure.
4517 * src/closure.c (closure): Explain sorting of core and itemset, which
4518 is required for this function to behave correctly.
4519 * src/closure.h (closure): Mention sorting.
4521 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
4523 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4524 move the check for disabled transitions to an aver since conflict
4525 resolution hasn't happened yet.
4527 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4528 labels a state as inconsistent just because it has error transitions.
4529 The original form of this check appeared in revision 1.1 of lalr.c,
4530 which was committed on 1991-12-21. Now (at least), changing the
4531 consistency label on such a state appears to have no useful effect in
4532 any of the places it is examined, which I enumerate below. The key
4533 point to understanding each item in this enumeration is that a state
4534 with an error transition is labelled consistent in the first place only
4535 if it has no rules, so the check cannot matter for states that have
4536 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4537 to try to identify its conflicts, and a state must have *rules* to have
4538 conflicts. (2) Labelling a state as inconsistent will affect how
4539 action_row sets the default *rule* for the state. (3) Labelling a
4540 state as inconsistent will cause build_relations to add lookback edges
4541 to *rules* in that state.
4542 * src/state.h (struct state): Word the comment for member consistent
4545 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
4547 Don't depend on C99 features.
4548 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
4549 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
4550 * src/reader.c (check_and_convert_grammar): Fix for-loop.
4551 * src/state.c (state_mark_reachable_states): Fix for-loop.
4552 (state_remove_unreachable_states): Fix for-loop.
4554 Don't widen struct state with member reachable just to temporarily
4555 record reachability. Instead, use a local bitset.
4556 * src/state.h (struct state): Remove member.
4557 * src/state.c (state_new): Don't initialize it.
4558 (state_mark_reachable_states): Rename to...
4559 (state_record_reachable_states): ... this, and use bitset.
4560 (state_remove_unreachable_states): Use bitset.
4562 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
4564 * src/Makefile.am (yacc): Quote target action commands properly so
4565 that the yacc script isn't corrupt. Reported by Hans Aberg at
4566 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
4568 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
4569 the case of pure parsers. Reported by Frans Englich at
4570 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
4571 * THANKS: Add Frans Englich.
4573 * NEWS (2.3a+): In the %code entry, reference section `Bison
4574 Declaration Summary' from the manual now since the %code summary has
4576 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
4577 in the rules section must be terminated by semicolons.
4579 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
4581 Extend the front-end API for %define variables to more completely
4582 mirror the back-end. This will be useful in the future.

4798 Undo my 2007-02-07 change, switching back to the c-strcase module
4799 introduced in the 2007-02-03 change. Bruno Haible reported that
4800 the 2007-02-07 change would be dangerous in Turkish if we add a
4801 language whose name contains "i", since "i" is not lowercase "I"
4803 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
4804 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
4805 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
4806 * m4/.cvsignore: Remove strcase.m4.
4807 * src/getargs.c: Revert 2007-02-07 change, as follows.

4809 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
4811 2007-02-11 Bruno Haible <bruno@clisp.org>
4813 Enable the Java related testsuite tests when the only Java compiler
4814 found is a gcj < 4.3. Discussed at
4815 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
4816 * configure.ac (gt_JAVACOMP): Don't specify a target_version.

4824 * src/reader.c (packgram): Move translation of rule actions from the
4825 beginning of packgram to...
4826 (check_and_convert_grammar): ... here right before packgram is invoked
4827 so it's easier to write more complete comments, and remove redundant
4830 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
4832 As in semantic actions, make @$ in %initial-action, %destructor, and
4833 %printer imply %locations.
4834 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
4836 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...

4838 @$ in %destructor implies %locations,
4839 @$ in %printer implies %locations): ... these new test cases.
4841 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>

4844 now that gnulib strcase has been fixed.
4845 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
4846 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
4847 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
4848 * m4/.cvsignore: Add strcase.m4.
4849 * src/getargs.c: Revert 2007-02-03 change, as follows.
4850 Don't include c-strcase.h.
4851 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4852 strcasecmp has "unspecified behavior" outside the POSIX locale,
4853 but it works fine in practice if at least one argument is ASCII,
4854 as is the case in Bison.
4856 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
4858 * tests/java.at: Skip tests if only one of javac/java is present.
4859 Reported by Joel E. Denny.

4864 * data/lalr1.java (Stack): Work around old verifiers that disallow
4865 access to the private fields of an inner class, from the outer class.
4866 We can make Stack's fields public because user code doesn't have access
4867 to the instance of Stack used by parse(). Reported by Paul Eggert.
4869 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4871 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4872 the right spot for these files?
4873 * bootstrap.conf (gnulib_modules): Add c-strcase.
4874 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4876 * src/getargs.c: Include c-strcase.h.
4877 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4878 to avoid unspecified behavior.
4880 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>

4888 * data/c++.m4: Adjust default definitions of %define variables.
4889 * data/java.m4: Adjust default definitions of %define variables.
4890 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according

4921 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4922 at_directive_argv arguments so these no longer have to be global
4923 variables. Also, update the implementation for the following changes.
4924 (fail_for_at_directive_too_many_args,
4925 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4926 (at_directive_name): Remove as at_directive_argv[0] will be used for
4928 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4929 for the directive name.

4933 (SC_AT_DIRECTIVE_ARG): Rename to...
4934 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4935 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4936 (scan_skel): Move yylex_destroy to...
4937 (skel_scanner_free): ... here.
4938 * tests/skeletons.at (installed skeleton file name): Rename to...
4939 (installed skeleton file names): ... this.
4941 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4943 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4944 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4945 Summary" not "Directives".
4946 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4947 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4948 since the former is now the more complete one.
4949 (Prologue Alternatives): Likewise and do the same for %defines.
4950 (Table of Symbols): Add summary of %code, add summary of %define, and
4951 move full %code documentation to...
4952 (Decl Summary): ... here for consistency with other entries in these
4954 Move %define entry in order to keep this list alphabetized.
4955 Reword %define entry a little to put less emphasis on the skeleton
4956 concept, which most users shouldn't have to think about.

4969 Simplify implementation of unqualified %code, implement macros for
4970 uniform treatment of boolean %define flags. Document %define.

5040 and Joel E. Denny <jdenny@ces.clemson.edu>
5042 Clean up %define and %code implementation in M4 some. Most
5043 importantly, rename all related macros to be in the b4_percent_define
5044 and b4_percent_code namespaces. Also, complete support for `.' in
5045 %define variable names and %code qualifiers.
5046 * data/bison.m4 (b4_check_user_names): Check for special
5047 "SKELETON-NAMESPACE(name)" macros instead of using two nested
5049 (b4_get_percent_define, b4_get_percent_code): Rename to...
5050 (b4_percent_define_get, b4_percent_code_get): ... these.
5051 Extend documentation with examples.
5052 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
5053 b4_percent_define_skeleton_variables and
5054 b4_percent_code_skeleton_qualifiers.
5055 Expect any value for the %define variable `foo' to be stored in the
5056 macro named `b4_percent_define(foo)'; expect any %code blocks for the
5057 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
5058 expect any unqualified %code blocks to be stored in a macro named
5059 `b4_percent_code_unqualified'.
5060 Use m4_indir so that %define variable names and %code qualifiers can
5061 contain `.', which is allowed by the grammar parser.
5062 (b4_percent_define_default): New macro to set a default value for a
5064 (m4_wrap): Update wrapped code, and fix some underquoting.
5065 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
5066 Expect grammar uses of %define variables and %code qualifiers to be
5067 defined in b4_percent_define_user_variables and
5068 b4_percent_code_user_qualifiers.
5069 * data/c++.m4: Use b4_percent_define_default rather than
5070 m4_define_default. Fix some underquoting. Skeleton usage of %define
5071 variable define_location_comparison now implies skeleton usage of
5072 %define variable filename_type.
5073 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5074 data/push.c, data/yacc.c: Update macro names.
5075 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
5078 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5080 DJGPP specific issues.
5082 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
5083 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
5085 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5087 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
5088 run parsers in all tests so that Valgrind is invoked during
5089 maintainer-check-valgrind.
5090 (Duplicate representation of merged trees): Free all semantic values.
5091 (Duplicated user destructor for lookahead): Likewise.
5093 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5095 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
5096 command-line prefix.
5097 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
5098 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
5099 miss Valgrind messages.
5100 (Exploding the Stack Size with Malloc): Likewise.
5102 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5104 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
5105 locals. Reported by Juan Manuel Guerrero at
5106 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
5107 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
5108 Fix some indentation also.
5109 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
5110 explaining this issue.
5112 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
5113 and Joel E. Denny <jdenny@ces.clemson.edu>
5115 Simplify union and prologue handling, and escape union and lex/parse
5116 params with digraphs.
5117 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
5118 values to the empty string since these are no longer guaranteed
5119 initialized by the front-end.
5120 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
5121 braces around b4_user_stype since this is no longer done by the
5123 * src/files.c, src/files.h (pre_prologue_obstack,
5124 post_prologue_obstack): Remove.
5125 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
5126 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
5127 with digraphs. This fixes lex params and parse params.
5128 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
5129 * src/output.c (prepare): Remove muscle insertion of the prologues.
5130 (output): Remove freeing of pre_prologue_obstack and
5131 post_prologue_obstack.
5132 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
5133 than prologue_augment for prologue parsing so you don't need prologue
5135 (grammar_declaration): For %union RHS, use `braceless' instead of
5136 "{...}" so that braces are already stripped and code is escaped with
5138 * src/reader.c (prologue_augment): Remove.
5139 (reader): Remove initialization of pre_prologue_obstack and
5140 post_prologue_obstack.
5141 * src/reader.h (prologue_augment): Remove.
5143 * data/c.m4: Remove stray parenthesis.
5145 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5147 Remove quotes from variables names in %define directives and from
5148 qualifiers in %code directives, and restrict the characters that are
5149 allowed in them to M4-friendly ones. For %define, continue to support
5150 the quoted form as a deprecated feature. Discussed starting at
5151 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
5152 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
5154 * doc/bison.texinfo (Prologue Alternatives): Update.
5155 (Decl Summary): In %defines entry, update mention of `%code requires'
5156 and `%code provides'.
5157 (C++ Location Values): Update %define uses.
5158 (Calc++ Parser Interface): Likewise.
5159 (Calc++ Parser): Likewise, and update `%code requires' uses.
5160 (Table of Symbols): Update %code documentation.
5161 * src/parse-gram.y (prologue_declaration): For %define variables, use
5162 `variable' instead of `STRING'.
5163 (grammar_declaration): For %code qualifiers, use `ID' instead of
5165 (variable): New nonterminal that takes an `ID' or a `STRING'.
5166 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
5168 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
5169 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
5170 (%define errors): Update %define uses.
5172 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5174 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
5175 instead of muscle_insert for %define values so that M4-special
5176 characters are replaced with digraphs.
5177 * tests/input.at (%define errors): Extend to check weird values.
5179 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5181 Instead of having skeletons declare all valid %define variables and
5182 %code qualifiers, provide macros that retrieve the associated values
5183 and build these lists automatically. Thus Bison will now warn when a
5184 variable or qualifier is not used by the skeleton in the current
5185 invocation regardless of whether it might sometimes be used by that
5186 skeleton in other invocations. Also, move all %define value macros to
5187 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
5188 form, which is replaced by %code.
5189 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
5190 (b4_check_user_names): ... this, and change the series of valid name
5191 arguments to a single list argument for names used in the skeleton
5192 similar to the existing list argument for names used in the grammar.
5193 Warn instead of complaining.
5194 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
5195 values and %code code, to format %code code properly, and to build
5196 lists of all %define variables and %code qualifiers used in the
5197 skeleton: b4_skeleton_percent_define_variables and
5198 b4_skeleton_percent_code_qualifiers.
5199 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
5201 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
5202 the skeleton names lists can finish building first. In place of
5203 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
5204 expect the lists b4_user_percent_define_variables and
5205 b4_user_percent_code_qualifiers.
5206 * data/c++.m4: Where setting default values for b4_parser_class_name,
5207 b4_location_type, b4_filename_type, b4_namespace, and
5208 b4_define_location_comparison, update their names to the
5209 b4_percent_define_ namespace.
5210 * data/glr.c: Don't use b4_check_percent_define_variables and
5211 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
5212 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
5213 (b4_parser_class_name, b4_namespace): Define these using
5214 b4_get_percent_define for parser_class_name and namespace.
5215 * data/location.cc: Use b4_get_percent_define.
5216 * data/push.c: Don't use b4_check_percent_define_variables and
5217 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
5218 * data/yacc.c: Likewise, and don't call m4_exit in
5219 b4_use_push_for_pull_if or m4_wrap code will never execute.
5220 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
5222 (muscle_grow_user_name_list): ... this for consistency with the
5223 terminology used in bison.m4.
5224 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
5225 %define variable names, and rename muscle used_percent_define_variables
5226 to user_percent_define_variables.
5227 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
5228 user_percent_code_qualifiers.
5230 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
5231 {CODE} form is no longer accepted.
5232 * tests/input.at (Reject bad %code qualifiers): Rename to...
5233 (Reject unused %code qualifiers): ... this, and update test output.
5234 (%define error): Update test output.
5236 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
5238 Check for unrecognized %define variables similar to checking for
5239 unrecognized %code qualifiers. Check for redefined %define variables.
5240 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
5242 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
5243 (b4_check_percent_define_variables): New, also wraps it.
5244 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
5245 variables using b4_check_percent_define_variables.
5246 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
5247 all those exercised in the test suite and all those listed in the
5248 `Default values' section of c++.m4. Are there others?
5249 * data/push.c, data/yacc.c: Declare no valid %define variables.
5250 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
5251 similar to muscle_find, but it works even when the muscle stores a
5253 (muscle_grow_used_name_list): New function for constructing the used
5254 name list muscles that b4_check_for_unrecognized_names requires.
5255 * src/parse-gram.y (prologue_declaration): Warn if a variable is
5256 %define'd more than once. Define the b4_used_percent_define_variables
5257 muscle with muscle_grow_used_name_list.
5258 (grammar_declaration): Abbreviate %code code with
5259 muscle_grow_used_name_list.
5260 * tests/input.at (%define errors): New.
5262 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5264 Provide warn_at, complain_at, and fatal_at function callbacks to the
5265 skeletons, and use this for %code qualifier complaints.
5266 * data/bison.m4 (b4_error_at): New, invoked by...
5267 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
5268 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
5269 @fatal_at(...@) directives.
5270 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
5271 qualifiers in b4_used_percent_code_qualifiers and to use
5273 * src/location.c, src/location.h (boundary_set_from_string): New global
5275 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
5277 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
5278 to b4_used_percent_code_qualifiers.
5279 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
5281 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
5282 (lineno): Rename to...
5283 (out_lineno): ... this so I don't misunderstand it again.
5284 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
5285 here; these newlines are in the input but not the output file.
5286 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
5287 (at_directive_perform): ... this new static function, and add handling
5288 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
5290 * tests/input.at (Reject bad %code qualifiers): Update test output with
5291 locations and extend.
5293 * tests/output.at (Output file name: [, Output file name: ]): Remove
5294 bogus comment about these tests failing.
5296 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5298 Clean up b4_check_percent_code_qualifiers a little.
5299 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
5300 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
5301 documentation and add examples.
5302 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
5305 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5307 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
5308 unreliable -- especially when they're hidden inside another macro.
5309 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
5310 data/c.m4: Remove m4_divert(-1).
5311 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5312 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
5313 m4_divert_push(0) and m4_divert_pop(0).
5314 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
5315 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
5316 pushed and popped by m4sugar, should be first on the stack.
5318 Provide warn, complain, and fatal function callbacks to the skeletons.
5319 This provides more flexibility than m4_fatal, improves the error
5320 message format, and captures messages for translation. Discussed
5322 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
5323 * data/bison.m4 (b4_error): New, invoked by...
5324 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
5325 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
5326 directives. Because these M4 macros might be called when the current
5327 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
5328 the previous removal of uses of m4_divert, which caused trouble.
5329 (b4_check_percent_code_qualifiers): Use b4_complain instead of
5330 m4_fatal to report unrecognized %code qualifiers.
5331 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
5332 push parser requests.
5333 * data/glr.c: Use b4_complain instead of m4_fatal to report
5334 non-deterministic push parser requests.
5335 Update @output usage to @output(...@) form.
5336 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
5337 report missing %defines. Update @output usage to @output(...@) form.
5338 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
5340 * src/main.c (main): Invoke skel_scanner_free.
5341 * src/scan-skel.h (skel_scanner_free): Prototype new function.
5342 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
5343 obstack_for_string from flex-scanner.h.
5344 (YY_DECL): Use to declare skel_lex static.
5345 (decode_at_digraphs): Remove; now handled in the new
5346 SC_AT_DIRECTIVE_ARG start condition.
5347 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
5349 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
5350 at_directive_argv): New static globals.
5351 (INITIAL): Use fail_for_invalid_at.
5352 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
5353 recognize the start of a generalized `@directive(...@)' form and
5355 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
5356 directive args (using the new obstack_for_string), to decode the
5357 contained @ diagraphs, and to perform the directive. It recognizes
5358 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
5360 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
5361 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
5363 (scan_skel): Initialize obstack_for_string on the first call.
5364 (skel_scanner_free): New function to free obstack_for_string.
5365 * tests/input.at (Reject bad %code qualifiers): Update test output.
5367 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
5369 Consolidate the 4 prologue alternative directives (%code, %requires,
5370 %provides, and %code-top) into a single %code directive with an
5371 optional qualifier field. Discussed at
5372 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
5373 * NEWS (2.3a+): Rewrite the existing entry for the prologue
5375 * doc/bison.texinfo (Prologue Alternatives): Update.
5376 (Decl Summary): Update to %code "requires" and %code "provides".
5377 (Calc++ Parser): Update to %code "requires".
5378 (Table of Symbols): Remove entries for %requires, %provides, and
5379 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
5380 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
5381 are replaced by b4_percent_code_provides and b4_percent_code_requires,
5382 which are skeleton-specific.
5383 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
5384 declare what %code qualifiers it supports and to complain if any other
5385 qualifiers were used in the grammar.
5386 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
5387 and b4_user_code([b4_percent_code_provides]) in place of
5388 b4_user_requires and b4_user_provides.
5389 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
5390 Add b4_user_code([b4_percent_code_top]) and
5391 b4_user_code([b4_percent_code]).
5392 Invoke b4_check_percent_code_qualifiers.
5393 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
5394 PERCENT_REQUIRES): Remove.
5395 (grammar_declaration): Remove RHS's for %code-top, %provides, and
5396 %requires. Rewrite the %code RHS as the unqualified form defining the
5397 muscle b4_percent_code. Add another RHS for the qualified %code form,
5398 which defines muscles of the form b4_percent_code_QUALIFIER and the
5399 b4_used_percent_code_qualifiers muscle.
5400 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
5401 PERCENT_REQUIRES): Remove.
5402 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
5403 %code "requires" and %code "provides".
5404 * tests/input.at (Reject bad %code qualifiers): New.
5406 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
5408 Use the new code_props interface for destructors and printers.
5409 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
5410 printer_location members, and change the type of the destructor and
5411 printer members to code_props.
5412 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
5413 symbol_printer_get, semantic_type_destructor_set,
5414 semantic_type_printer_set, default_tagged_destructor_set,
5415 default_tagless_destructor_set, default_tagged_printer_set,
5416 default_tagless_printer_set): Use code_props in arguments and return
5417 types in place of char const * and location.
5418 (symbol_destructor_location_get, symbol_printer_location_get): Remove
5419 since the locations are now contained in the return of
5420 symbol_destructor_get and symbol_printer_get.
5421 * src/output.c (symbol_destructors_output, symbol_printers_output):
5423 (symbol_code_props_output): ... this to eliminate duplicate code.
5424 (output_skeleton): Update to use symbol_code_props_output.
5425 * src/reader.c (symbol_should_be_used): Update use of
5426 symbol_destructor_get.
5427 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5428 Update uses of the various _destructor_set and _printer_set functions.
5429 * src/symtab.c: (default_tagged_destructor_location,
5430 default_tagless_destructor_location, default_tagged_printer_location,
5431 default_tagless_printer_location): Remove since we...
5432 (default_tagged_destructor, default_tagless_destructor,
5433 default_tagged_printer, default_tagless_printer): ... change the type
5434 of these to code_props.
5435 (symbol_new, semantic_type_new, symbol_destructor_set,
5436 semantic_type_destructor_set, symbol_destructor_get,
5437 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
5438 symbol_check_alias_consistency, default_tagged_destructor_set,
5439 default_tagless_destructor_set, default_tagged_printer_set,
5440 default_tagless_printer_set): Update.
5441 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
5442 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
5444 (symbol_print): Use SYMBOL_CODE_PRINT.
5446 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
5448 Use the new code_props interface for rule actions.
5449 * src/symlist.h (symbol_list): Replace action, action_location, and
5450 used members with a code_props action_props member.
5451 * src/reader.c (symbol_should_be_used, grammar_rule_check,
5452 grammar_midrule_action, grammar_current_rule_merge_set,
5453 grammar_current_rule_symbol_append, packgram): Update.
5454 * src/scan-code.h (translate_rule_action): Remove, no longer used.
5455 * src/scan-code.l (handle_action_dollar): Update.
5456 (translate_rule_action): Remove, no longer used.
5457 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
5459 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5461 Use the new code_props interface in parse-gram.y.
5462 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
5463 Update all uses of translate_* functions to use the new code_props
5464 interface and to use gram_scanner_last_string_free and
5465 code_scanner_last_string_free where possible.
5466 (grammar_declaration): symbol_list_destructor_set and
5467 symbol_list_printer_set now perform the translation, so don't do it
5468 here. Use gram_scanner_last_string_free where possible.
5469 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
5470 translate_code): Remove, no longer used.
5471 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
5472 symbol_list_printer_set): Perform code translation here rather than
5473 depending on the caller to do so.
5475 * src/symlist.h (struct symbol_list): Correct some documentation typos.
5476 * src/scan-gram.h (gram_last_string): Remove declaration.
5477 * src/scan-gram.l (last_string): Declare it static.
5479 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5481 Encapsulate code properties and related functionality for the various
5482 destructors, printers, and actions into a code_props structure and
5483 interface. This patch merely implements code_props in scan-code.h and
5484 scan-code.l. Future patches will rewrite other modules to use it.
5485 Discussed starting at
5486 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
5487 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
5488 consistently initialize const structs that have an empty location
5490 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
5491 to ensure consistency.
5492 * src/scan-code.h (code_props): New structure.
5493 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
5494 function, macro, and const global variable for initializing a
5495 code_props with no code.
5496 (code_props_plain_init, code_props_symbol_action_init,
5497 code_props_rule_action_init, code_props_translate_code): The rest of
5498 the new code_props functional interface. Among other things, the init
5499 functions set the code_props kind field so that
5500 code_props_translate_code will know whether to behave like
5501 translate_symbol_action, translate_rule_action, or translate_code.
5502 These old translate functions must remain until all other modules are
5503 updated to use the new code_props interface.
5504 (code_scanner_last_string_free): New function similar to
5505 gram_scanner_last_string_free.
5506 (code_scanner_free): Add documentation.
5507 * src/scan-code.l: Implement the new interface.
5508 (code_lex): Make it static, add a code_props* argument, and remove the
5510 (last_string): New static global similar to the one in scan-gram.l.
5511 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
5513 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
5514 code_props since Bison may one day use this information for destructors
5516 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
5517 (handle_action_dollar): Use symbol_list_n_get and set used flag
5518 directly since symbol_list_n_used_set is removed.
5519 (translate_action): Add a code_props* argument and remove the rule,
5520 action, and location arguments. Pass the code_props* on to code_lex.
5521 (translate_rule_action, translate_symbol_action, translate_code):
5522 Rewrite as wrappers around the new code_props interface.
5523 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
5524 it would eventually need to break the encapsulation of code_props.
5526 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5528 * etc/.cvsignore: New.
5530 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5532 Add maintainer-push-check to run maintainer-check using push parsing in
5533 place of pull parsing where available.
5534 * Makefile.am (maintainer-push-check): New.
5535 * data/bison.m4 (b4_use_push_for_pull_if): New.
5536 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
5537 appropriately based on their existing values.
5538 (yypush_parse): Don't print push-parser-specific diagnostics if push
5539 parsing is being used in place of pull parsing.
5540 * data/yacc.c: If push parsing should replace pull parsing, redirect to
5542 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
5543 variable, and insert b4_use_push_for_pull_flag into muscles.
5544 * tests/Makefile.am (maintainer-push-check): New.
5546 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5548 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
5549 (whether successful or failed) so that yypush_parse can be invoked
5550 again to start a new parse using the same yypstate.
5551 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
5552 check multiple yypull_parse invocations on the same yypstate. For pull
5553 mode, extend to check multiple yyparse invocations.
5554 (Exploding the Stack Size with Alloca): Extend to try with
5556 (Exploding the Stack Size with Malloc): Likewise.
5558 * tests/calc.at (Simple LALR Calculator): Don't specify
5559 %skeleton "push.c" since %push-pull-parser implies that now.
5560 * tests/headers.at (export YYLTYPE): Don't check for the push
5561 declarations. Otherwise, this test case can't be used to see if push
5562 mode can truly emulate pull mode.
5563 * tests/input.at (Torturing the Scanner): Likewise.
5564 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
5565 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
5566 AT_YACC_IF, which now includes the case of push mode since %skeleton
5567 need not be used for push mode. This will be more intuitive once
5568 push.c is renamed to yacc.c.
5570 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5572 For push mode, convert yyparse from a macro to a function, invoke yylex
5573 instead of passing a yylexp argument to yypull_parse, and don't
5574 generate yypull_parse or yyparse unless %push-pull-parser is declared.
5575 Discussed starting at
5576 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
5577 * data/bison.m4 (b4_pull_if): New.
5578 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
5579 * data/push.c: Improve M4 quoting a little.
5580 (b4_generate_macro_args, b4_parenthesize): Remove.
5581 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
5582 any time a pull parser is requested.
5583 Don't #define this as a wrapper around yypull_parse. Instead, when
5584 both push and pull are requested, make it a function that does that
5586 (yypull_parse): If there's a b4_prefix, #define this to
5587 b4_prefix[pull_parse] when both push and pull are requested.
5588 Don't define this as a function unless both push and pull are
5590 Remove the yylexp argument and hard-code yylex invocation instead.
5591 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
5593 * src/getargs.c (pull_parser): New global initialized to true.
5594 * getargs.h (pull_parser): extern it.
5595 * src/output.c (prepare): Insert pull_flag muscle.
5596 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
5597 (prologue_declaration): Set both push_parser and pull_parser = true for
5598 %push-pull-parser. Set push_parser = true and pull_parser = false for
5600 * src/scan-gram.l: Don't accept %push_parser as an alternative to
5601 %push-parser since there's no backward-compatibility concern here.
5602 Scan %push-pull-parser.
5603 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
5604 instead of %push-parser.
5605 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
5606 prototype it in the module that calls yyparse.
5607 * tests/input.at (Torturing the Scanner): Likewise.
5608 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
5610 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
5612 Update etc/bench.pl. Optimize push mode a little (the yyn change
5613 deserves most of the credit).
5614 * Makefile.am (SUBDIRS): Add etc subdirectory.
5615 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
5616 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
5617 yytoken, yyval, and yyloc declarations to...
5618 (yyparse or yypush_parse): ... here to improve performance. For
5619 yypush_parse invocations after the first, be sure to assign yyn its old
5621 (yypstate_new): Don't bother initializing the yyresult field since the
5622 initial value isn't used.
5623 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
5624 remove the #define that, in push mode, set it to yyps->NAME.
5625 * etc/Makefile.am: New.
5626 * etc/bench.pl: Remove and build it instead from...
5627 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
5628 "tests/bison" from the build directory by default rather than just
5629 invoking "bison" from $PATH.
5630 (calc_grammar): Update push parser code: don't declare yylval globally,
5631 don't define yyparse_wrapper, and don't #define yyparse.
5632 (bench_grammar): Update to check all working combinations of yacc.c,
5633 push.c, impure, pure, pull, and push.
5635 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5637 For push mode, add pull wrappers around yypush_parse.
5638 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
5639 (yypull_parse): New function wrapping yypush_parse.
5640 (yyparse): New #define wrapping yypull_parse.
5641 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
5643 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
5644 prototype yylex in the module that calls yyparse, and don't prototype
5645 yyparse there. Otherwise, the yyparse expansion won't compile.
5646 * tests/input.at (Torturing the Scanner): Likewise.
5648 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5650 Enable push parsers to operate in impure mode. Thus, %push-parser no
5651 longer implies %pure-parser. The point of this change is to move
5652 towards being able to test the push parser code by running the entire
5653 test suite as if %push-parser had been declared.
5654 * data/push.c (yypush_parse): For impure mode, remove the
5655 yypushed_char, yypushed_val, and yypushed_loc arguments.
5656 Instead, declare these as local variables initialized to the global
5657 yychar, yylval, and yylloc.
5658 For the first yypush_parse invocation only, restore the initial values
5659 of these global variables when it's time to read a token since they
5660 have been overwritten.
5661 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
5663 * tests/calc.at (Simple LALR(1) Calculator): Always declare
5664 %pure-parser along with %push-parser since this test case was designed
5665 for pure push parsers.
5666 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
5667 (AT_YACC_OR_PUSH_IF): New.
5668 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
5669 add a note that it's still wrong for some cases (as it has been for a
5671 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
5672 %push-parser no longer implies %pure-parser.
5674 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5676 Remove some unnecessary differences between the pull parser code and
5677 the push parser code. This patch enables yynerrs in push mode.
5678 * data/push.c: Reformat M4 a little.
5679 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
5680 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
5681 because push mode is on. Instead, if pure mode is on, move yynerrs
5683 (b4_declare_parser_state_variables): ... here.
5684 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
5685 to yyps->NAME so it can be used in yypush_parse.
5686 (yypush_parse): Don't omit uses of yynerrs in push mode.
5688 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5690 Fix bug such that the first pushed token's value and location are
5691 sometimes overwritten (sometimes by %initial-action) before being used.
5692 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
5693 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
5694 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
5695 more closely mimic the pull parser logic.
5696 Don't copy the pushed token to yychar, yylval, and yylloc until it's
5697 time to read a token, which is after any initialization of yylval and
5699 (gottoken): Rename label to...
5700 (yyread_pushed_token): ... for clarity and to avoid infringing on the
5703 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5705 Rearrange initialization of the parser state variables so that the
5706 skeleton doesn't have to have a copy for pull mode and another for push
5707 mode. This patch also fixes at least a bug such that yylloc was not
5708 initialized (with b4_location_initial_line and
5709 b4_location_initial_column) upon calling yypush_parse. However, that
5710 initialization now overwrites the first token's location;
5711 %initial-action assigning @$ already did the same thing, and both bugs
5712 will be fixed in a later patch.
5713 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
5714 (b4_declare_parser_state_variables): Remove initialization of yytoken,
5715 yyss, yyvs, yyls, and yystacksize.
5716 (yypstate_new): Remove initialization of some yypstate fields: yystate,
5717 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
5719 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
5720 yyps->NAME so it can be used in yypush_parse.
5721 (yyparse or yypush_parse): For yypush_parse, don't print the
5722 "Starting parse" diagnostic for invocations after the first.
5723 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
5724 yypush_parse, only do it for the first invocation.
5725 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
5726 initialization to occur in yypush_parse but only on the first
5729 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5731 * data/push.c: Add CPP guards around push parser declarations in both
5732 the header and the code file.
5733 In the code file, move the push parser declarations to the same place
5734 they appear in the header file.
5735 Clean up the M4 some, especially the inconsistent underquoting in
5736 some b4_c_function_def and b4_c_function_decl uses.
5738 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5740 Encapsulate the push parser state variables into an M4 macro so the
5741 push skeleton doesn't have to list them again for pull mode's yyparse.
5742 For push mode, remove yypush_parse's local equivalents of these
5743 variables to eliminate unnecessary copying between the two sets at
5744 run-time. This patch also fixes at least a bug related to multiple
5745 %initial-action invocations in push mode.
5746 * data/push.c (b4_declare_parser_variables): Rename to...
5747 (b4_declare_scanner_communication_variables): ... this for clarity and
5749 (b4_declare_yyparse_variables): Remove and move its contents to the one
5750 spot where it was invoked.
5751 (b4_declare_parser_state_variables): New macro containing the parser
5752 state variables required by push mode.
5753 (struct yypstate): Replace all fields but yynew with
5754 b4_declare_parser_state_variables.
5755 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
5756 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
5757 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
5758 (yyparse or yypush_parse): For yyparse in pull mode, replace local
5759 parser state variable declarations with
5760 b4_declare_parser_state_variables.
5761 Don't initialize parser state variables when calling yypush_parse since
5762 yypstate_new already does that.
5763 Invoke the user's initial action only upon the first yypush_parse
5765 Remove all code that copies between the local parser state variables
5768 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5770 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
5771 prevent a name collision in a future patch where these names will
5772 sometimes be #define'd.
5773 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
5774 since it no longer has the same name as the existing argument.
5775 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
5777 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
5778 and Joel E. Denny <jdenny@ces.clemson.edu>
5780 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
5781 that the argument is case-insensitive, and there's no `=' here.
5782 For the %skeleton entry, mention that %language is better.
5783 (Bison Options): Likewise for --language and --skeleton. Move the
5784 --skeleton entry so that the `Tuning the parser' section is sorted
5785 alphabetically on long options.
5786 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
5787 %language directive in detail here; cross-reference the %language
5788 documentation instead.
5789 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
5790 `%require "2.3b"' so that the example is always up-to-date.
5791 (Table of Symbols): Add entries for %language and %skeleton.
5792 * examples/extexi (normalize): Instead of replacing every %require
5793 argument with the current Bison version, just substitute for
5794 `@value{VERSION}'. This guarantees that we're testing what actually
5795 appears in the documentation.
5796 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
5797 rather than `@VERSION@'.
5799 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5801 * NEWS: Reword the %language news a bit, and put it earlier.
5803 * src/getargs.c (skeleton_arg): Last arg is now location const *.
5804 Rewrite to simplify the logic.
5805 (language_argmatch): Likewise.
5806 (program_name): We now own this var.
5807 * src/getargs.h (struct bison_language): Use char[] rather than
5810 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
5812 * src/complain.c (program_name): Remove decl; no longer needed.
5813 * src/main.c (program_name): Remove; now belongs to getargs.
5815 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
5817 * NEWS: Document %language.
5819 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
5821 * data/c-skel.m4, data/c++-skel.m4: New files.
5822 * data/glr.c: Complain on push parsers.
5824 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
5826 (Decl Summary): Document %language and %skeleton.
5827 (Command line): Document -L.
5829 * examples/extexi: Rewrite %require directive.
5830 * examples/calc++/Makefile.am: Pass VERSION to extexi.
5832 * src/files.c (compute_exts_from_gc): Look in language structure
5834 (compute_file_name_parts): Check whether .tab should be added.
5835 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
5836 (language, skeleton_arg, language_argmatch): New.
5837 (long_options): Add --language.
5838 (getargs): Use skeleton_arg, add -L/--language.
5839 * src/getargs.h: Include location.h.
5840 (struct bison_language, language, skeleton_arg, language_argmatch): New.
5841 * src/output.c (prepare): Pick default skeleton from struct language.
5842 Don't dispatch C skeletons here.
5843 * src/parse-gram.y (PERCENT_LANGUAGE): New.
5844 (prologue_declaration): Add "%language" rule, use skeleton_arg.
5845 * src/scan-gram.l ("%language"): New rule.
5847 * tests/calc.at: Test %skeleton and %language.
5848 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
5849 (AT_GLR_IF): Look for %skeleton "glr.cc".
5850 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
5851 (AT_YACC_IF): Reject %language.
5853 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5855 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5856 since it wasn't used; only the typedef name 'semantic_type' is needed.
5857 Also, omit trailing white space.
5859 * bootstrap: Sync from coreutils.
5860 (gnulib_extra_files): Add build-aux/announce.gen.
5861 (slurp): Adjust .gitignore files like .cvsignore files.
5862 * build-aux/announce-gen: Remove from CVS, since bootstrap
5865 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5867 Make %push-parser imply %pure-parser. This fixes several bugs; see
5868 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5869 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5871 * data/push.c: Don't bother testing b4_push_if when deciding whether
5872 to expand b4_declare_parser_variables globally.
5873 (yypush_parse): Likewise in here.
5875 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5876 (yy_reduce_print): Reformat M4 for readability.
5878 2006-12-15 Bob Rossi <bob@brasko.net>
5879 and Joel Denny <jdenny@ces.clemson.edu>
5881 * data/push.c (yypstate): Add typedef, and update all uses of
5882 struct yypstate to just yypstate.
5883 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5885 2006-12-14 Bob Rossi <bob@brasko.net>
5887 * data/push.c (yypush_parse): Declare prototype regardless of
5890 2006-12-14 Bob Rossi <bob@brasko.net>
5892 * data/push.c (yyparse): Remove the prototype and the #define when in
5895 2006-12-13 Bob Rossi <bob@brasko.net>
5897 * data/push.c (yypstate_init): Rename to...
5898 (yypstate_new): ... this and use b4_c_function_def.
5899 (yypstate_delete): New.
5900 (yypush_parse): Change parameters yynval and yynlloc to be const.
5901 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5902 yypstate_delete functions.
5904 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5906 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5907 strange test case titles. Reported by Bob Rossi.
5909 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5911 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5912 of potential ambiguities in GLR grammers.
5914 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5916 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5917 `bison ', use m4_index instead of m4_substr since chopping up a string
5918 containing M4-special characters causes problems here.
5920 Fix a couple of bugs related to special characters in user-specified
5921 file names, and make it easier for skeletons to compute output file
5922 names with the same file name prefix as Bison-computed output file
5924 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5925 b4_parser_file_name and b4_spec_defines_file instead of
5926 @output_parser_name@ and @output_header_name@, which are now redundant.
5927 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5928 b4_parser_file_name, b4_spec_defines_file, and the new
5929 @basename(FILENAME@) instead of @output_parser_name@ and
5930 @output_header_name@, which inappropriately escaped the file names as
5932 * src/files.c (all_but_ext): Remove static qualifier.
5933 (compute_output_file_names): Move `free (all_but_ext)' to...
5934 (output_file_names_free): ... here since all_but_ext is needed later.
5935 * src/files.h (all_but_ext): Extern.
5936 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5937 exactly what MUSCLE_INSERT_STRING used to do.
5938 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5939 characters are escaped properly.
5940 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5942 For pkgdatadir muscle, maintain previous functionality by using
5943 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5944 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5945 digraphs would never be expanded. Hopefully no one has M4-special
5946 characters in his Bison installation path.
5947 * src/scan-skel.l: Don't parse @output_header_name@ and
5948 @output_parser_name@ anymore since they're now redundant.
5949 In @output, use decode_at_digraphs.
5950 Parse a new @basename command that invokes last_component.
5951 (decode_at_digraphs): New.
5952 (BASE_QPUTS): Remove unused.
5953 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
5954 (Output file name): New tests.
5956 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
5958 Warn about output files that are generated by the skeletons and that
5959 conflict with other output files.
5960 * data/glr.c: Don't generate the header file here when glr.cc does.
5961 * src/files.c (file_names, file_names_count): New static globals.
5962 (compute_output_file_names): Invoke output_file_name_check for files
5963 not generated by the skeletons and remove existing checks.
5964 (output_file_name_check): New function that warns about conflicting
5966 (output_file_names_free): Free file_names.
5967 * src/files.h (output_file_name_check): Declare.
5968 * src/scan-skel.l: Invoke output_file_name_check for files generated by
5970 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
5971 (Conflicting output files): New tests.
5973 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5975 * doc/bison.texinfo: Fix a couple of typos.
5977 2006-12-08 Bob Rossi <bob@brasko.net>
5979 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
5981 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
5983 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
5984 (yypush_parse): Rename yypvars argument to yyps and remove redundant
5986 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
5987 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
5989 2006-12-07 Bob Rossi <bob@brasko.net>
5990 and Joel Denny <jdenny@ces.clemson.edu>
5992 * data/push.c (yypvarsinit): Change return type from void* to struct
5993 yypvars*. No longer cast to void* on return.
5994 (struct yypvars): Remove yylen since it need not be remembered between
5995 yypushparse invocations.
5996 (yypushparse): Don't copy between yylen and pv->yylen.
5998 2006-12-05 Bob Rossi <bob@brasko.net>
6000 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
6001 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
6002 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
6003 (struct yypvars): Remove b4_declare_parser_variables.
6004 (yypvarsinit): Remove init code for removed variables.
6005 (global scope): Do not declare b4_declare_parser_variables if
6007 (yypushparse): Add b4_declare_parser_variables.
6008 Init new local variables, and remove init code for removed
6011 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
6012 and yyparse for other modes.
6013 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
6014 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
6015 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
6016 (AT_PURE_LEX_IF): True if pure or push parser.
6018 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
6020 Document Yacc prologue alternatives and default %destructor's and
6021 %printer's as experimental. Don't mention Java yet. Discussed at

6040 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
6041 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
6042 all but one occurrence of %name-prefix.
6043 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
6044 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
6045 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
6046 occurrence of each of %file-prefix and %output. Add check for %defines
6048 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
6049 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
6050 Remove the `=' from %output.
6052 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
6054 Don't escape $ in test case titles since Autoconf 2.61 now does that
6056 * tests/actions.at (Default %printer and %destructor are not for error
6057 or $undefined): Here.
6058 (Default %printer and %destructor are not for $accept): Here.
6059 * tests/input.at (Invalid $n and @n): Here.
6061 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
6063 Rename <!> to <>. Discussed starting at
6064 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.

6070 * src/symlist.c (symbol_list_default_tagless_new): Update comment.
6071 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
6073 * tests/actions.at (Default tagless %printer and %destructor,
6074 Default tagged and per-type %printer and %destructor,
6075 Default %printer and %destructor are not for error or $undefined,
6076 Default %printer and %destructor are not for $accept,
6077 Default %printer and %destructor for mid-rule values): Update.
6078 * tests/input.at (Default %printer and %destructor redeclared,
6079 Unused values with default %destructor): Update.
6081 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>

6094 grammar is maintained with Bison's highest standards.
6095 * src/getargs.c: Fix some typos in Doxygen comments.
6097 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
6099 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
6100 later. Reported by Paul Eggert in
6101 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
6102 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
6103 * src/scan-code.l (translate_action): Don't bother invoking
6104 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
6105 (code_scanner_free): Instead of invoking
6106 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

6111 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
6113 * src/files.c (tr): Change return type to void.
6114 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
6115 has been called previously for the same key.
6116 (muscle_find): Return storage instead of value so that
6117 --enable-gcc-warnings doesn't produce warnings that the return discards
6118 const. aver that the value and storage are the same since storage
6119 could potentially be NULL when value is not.
6120 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
6123 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6125 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
6126 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
6127 us a slightly cleaner distribution, and also works.
6128 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
6131 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
6132 and Paul Eggert <eggert@cs.ucla.edu>
6134 Don't let Bison leak memory except when it complains.
6135 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
6136 (spec_defines_file, dir_prefix): Now char *, not const char *,
6137 since they are freed.
6138 * src/files.c: Likewise.
6139 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
6141 (tr): Now operates in-place. All uses changed.
6142 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
6144 (compute_file_name_parts, compute_output_file_names): Don't store
6145 read-only data in variables that will be freed.
6146 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
6147 src_extension, and header_extension.
6148 (output_file_names_free): New public function to free
6149 spec_verbose_file, spec_graph_file, spec_defines_file,
6150 parser_file_name, and dir_prefix.
6151 * src/getargs.c (getargs): Don't store read-only data in variables that
6153 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
6154 (which previously existed but was unused), and quotearg_free.
6155 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
6156 * src/muscle_tab.c: Likewise.
6157 (muscle_entry): Make the value char const *,
6158 and add a new storage member that is char * and can be freed.
6159 (muscle_entry_free): New private function.
6160 (muscle_init): Use it instead of free.
6161 (muscle_insert, muscle_grow): Update and use new storage member.
6162 (muscle_code_grow): Free the string passed to muscle_grow
6163 since it's not needed anymore.
6164 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
6165 add a new `char *code' member.
6166 ("{...}"): Declare semantic type as code.
6167 * src/scan-code.h (translate_rule_action):
6168 (translate_symbol_action, translate_code, translate_action): Return
6169 `char const *' rather than `char *' since external code should not free
6171 * src/scan-code.l: Likewise.
6172 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
6173 which is "{...}" in the parser.
6174 * tests/Makefile.am (maintainer-check-valgrind): Set
6175 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
6177 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
6179 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
6180 expecting a non-zero exit status sets --leak-check=summary and
6181 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
6182 this case, and we don't want to hear about it.
6184 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6186 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
6187 instead of from the template, to simplify configuration a bit.
6188 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
6189 and m4/wint_t.m4, as they are needed with the latest gnulib.

6200 the value is a set/used mid-rule value unless
6201 --warnings=midrule-values was specified.
6202 * tests/input.at (Unused values, Unused values before symbol
6203 declarations): Run tests with and without --warnings=midrule-values.
6205 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
6206 than LIST_FREE directly.
6208 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
6210 Finish implementing --warnings=error, which should not be implied by
6211 --warnings=all (or by its synonyms -W and --warnings without

6218 "error - warnings are errors" does not appear above "all - all of the
6220 (getargs): For -W and --warnings without subarguments, don't let
6221 FLAGS_ARGMATCH set warnings_error in warnings_flag.

6227 empty subargument list. For example: `bison --warnings= parser.y'.
6229 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
6231 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
6232 the parser header file so that gcc doesn't warn.
6234 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
6236 Split the default %destructor/%printer into two kinds: <*> and <!>.
6237 Discussed starting at

6261 (symbol_destructor_get, symbol_destructor_location_get,
6262 symbol_printer_get, symbol_printer_location_get): Implement tagged
6263 default and tagless default cases.

6282 Don't apply the default %destructor/%printer to an unreferenced midrule
6284 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
6285 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
6286 like $@n instead of just @n so that the default %destructor/%printer
6287 logic doesn't see them as user-defined symbols.
6288 (symbol_is_dummy): Check for both forms of the name.
6289 * src/reader.c (packgram): Remove the `$' from each midrule symbol
6290 name for which the midrule value is referenced in any action.
6291 * tests/actions.at (Default %printer and %destructor for mid-rule

6299 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
6301 (packgram): Before invoking grammar_rule_check on any rule, make sure
6302 all actions have already been scanned in order to set `used' flags.
6303 Otherwise, checking that a midrule's $$ is set will not always work

6311 More improvements to the documentation of the prologue alternatives:
6312 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
6314 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
6315 some text to clarify the relative importance of the new directives and
6316 to show how these directives may be viewed as code labels.
6318 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
6320 Similar to the recently removed %before-header, add %code-top as the
6321 alternative to the pre-prologue. Mentioned at
6322 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
6323 Also, let the prologue alternatives appear in the grammar section.
6324 * src/parse-gram.y (PERCENT_CODE_TOP): New token.

6380 In messages and comments, say e.g., "checked-out sources",
6381 rather than "CVS sources".
6382 (version_controlled_file): New function. Work for git as well as
6383 for CVS. Don't use grep's -q option.
6384 (slurp): Call it here, in place of CVS-specific code.
6386 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
6388 Fix testsuite for ./configure --enable-gcc-warnings:
6389 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
6390 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
6391 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
6392 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.

6431 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
6433 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
6434 variable was sometimes used without being initialized. This
6435 messed up the installation of the INSTALL file in some cases.
6437 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
6439 * bootstrap (usage, main program, symlink_to_gnulib): Add option
6440 --copy. Inspired by a suggestion from Bruno Haible.
6442 2006-10-03 Jim Meyering <jim@meyering.net>
6444 * bootstrap: Undo last change to this file, since now gnulib-tool
6445 sticks with the automake default in generating dependencies.
6447 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
6449 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
6450 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
6452 * doc/bison.1: Add copyright notice.

6473 * src/print_graph.c: Include graphviz.h rather than vcg.h.
6474 (static_graph, fgraph): Remove. All uses changed to pass
6475 arguments instead of sharing a static var.
6476 (print_core, print_actions, print_state, print_graph):
6477 Output graphviz format rather than VCG format.
6478 * tests/.cvsignore: Remove *.vcg; add *.dot.
6479 * tests/output.at: Expect *.dot files, not *.vcg files.

6482 accommodates the 2006-10-08 change.
6484 2006-10-11 Bob Rossi <bob@brasko.net>
6486 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.

6494 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
6495 in a push parser. Reindent slightly to match yacc.c better.
6497 2006-10-11 Bob Rossi <bob@brasko.net>

6511 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
6512 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
6513 b4_define_user_cde and uses): Remove.
6514 (b4_comment, b4_prefix, b4_sync_start): New.
6515 * data/bison.m4: New file, with most of the content removed from c.m4.
6516 * src/muscle_tab.h: Use "do {...} while(0)" throughout.

6523 Fix test failure reported by Tom Lane in
6524 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
6525 and try to make such failures easier to catch in the future.
6526 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
6527 that's now the caller's responsibility.
6528 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
6529 Set yychar = YYEOF if it's negative.
6530 * tests/actions.at (yylex): Abort if asked to read past EOF.

6540 Fix problems with translating English-language diagnostics.
6541 * bootstrap: Fix bug introduced in recent bootstrap changes, with
6542 respect to bison-runtime pot generation. The YY_ stuff
6543 wasn't being captured.
6544 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
6545 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
6546 * runtime-po/POTFILES.in: Add data/push.c.
6548 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
6550 Merge bootstrap changes from coreutils.
6552 2006-09-28 Jim Meyering <jim@meyering.net>
6554 Automatically generated dependencies are important even
6555 when all of the sources in a directory come from gnulib.
6556 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
6557 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
6559 2006-09-23 Jim Meyering <jim@meyering.net>
6561 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
6563 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>

6578 (YYPUSH_MORE): Add #define.
6579 (yypushparse): Modify return value.
6581 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6583 * stamp-h.in: Remove; no longer needed.
6584 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
6585 Remove config.h, config.hin, intl (no longer created).
6586 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
6589 Sync bootstrap from coreutils, as follows:
6591 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
6593 * bootstrap (symlink_to_gnulib): New function.
6594 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
6595 to copies-of-gnulib.
6596 (cp_mark_as_generated, slurp, gnulib_files):
6597 Avoid making a copy if it's the same as the old version.
6598 (gnulib_files): Add support for this variable (used by Bison).
6600 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6602 * src/getargs.c (usage): Rework to use conventions similar to
6603 coreutils, to make translation a bit easier and the code a bit
6604 smaller. Problem reported by Tim Van Holder.
6606 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
6608 Use some of gnulib's new modules, taken from coreutils.
6610 * bootstrap: Sync from coreutils, except add support for gnulib_files.
6611 * bootstrap.conf: New file.
6612 (gnulib_modules): Add configmake, inttypes, unistd.
6613 (XGETTEXT_OPTIONS): Add complain, complain_at,
6614 fatal, fatal_at, warn, warn_at, unexpected_end.
6615 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
6616 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
6618 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
6620 (GNULIB_AUTOCONF_SNIPPET): Remove.
6621 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
6623 * lib/.cvsignore: Add inttypes_.h.
6624 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
6625 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
6626 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
6627 no-longer-necessary initializations.
6628 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
6629 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
6630 use the unistd module.
6631 * src/system.h: Likewise.
6632 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
6633 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
6634 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
6635 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
6636 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
6637 * src/system.h: Include inttypes.h unconditionally, now that we
6638 use the inttypes module. Don't bother to include stdint.h, since
6639 inttypes.h now does that for us.
6640 (LOCALEDIR): Remove, now that we use the configmake module.
6641 * src/getargs.c: Include configmake.h.
6642 * src/main.c: Likewise.
6643 * src/output.c: Likewise.
6644 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
6645 not from $abs_top_builddir, since config.h moved.
6648 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
6649 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
6651 * src/parse-gram.y (symbol_declaration): Don't put statements
6652 before declarations; it's not portable to C89.
6653 * src/scan-code.l (handle_action_at): Likewise.
6655 * src/scan-code.l: Always initialize braces_level; the old code
6656 left it uninitialized and therefore had undefined behavior.
6658 Don't attempt to redefine 'assert', since it runs afoul of
6659 systems where standard headers (mistakenly) include <assert.h>.
6660 Instead, define and use our own alternative, called 'aver'.
6661 * src/reader.c: Don't include assert.h, since we no longer
6663 * src/scan-code.l: Likewise.
6664 * src/system.h (assert): Remove, replacing with....
6665 (aver): New function, taking a bool arg. All uses changed.
6666 * src/tables.c (pack_vector): Ensure that aver arg is bool,
6667 not merely an integer.
6669 2006-09-15 Bob Rossi <bob@brasko.net>
6671 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
6672 * data/c.m4 (YYPUSH): New.
6673 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.

6675 * src/getargs.h (push_parser): New declaration.
6676 * src/output.c (prepare): Add macro insertion of `push_flag'.
6677 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
6678 (prologue_declaration): Parse %push-parser.
6679 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
6680 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
6681 list of removed lines from the traces observed.
6682 (AT_CHECK_CALC_LALR): Added push parser tests.
6684 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
6686 * NEWS: Version 2.3a.
6687 * configure.ac (AC_INIT): Likewise.
6689 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
6690 "#define YYSTYPE int" that caused "make maintainer-check" to fail
6691 due to header ordering dependencies. I don't know why the #define
6694 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
6695 runtime cost when YYDEBUG is not defined, and so that some tests
6696 that used to fail now work. Problem and initial suggestion by
6698 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
6699 * data/glr.cc (b4_parser_class_name):
6700 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
6701 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
6702 (yydebug_) [YYDEBUG]: New member.
6703 (yycdebug_): Now defined only if YYDEBUG.
6704 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
6705 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
6706 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
6708 (debug_stream, set_debug_stream, debug_level, set_debug_level):
6709 Define only if YYDEBUG.
6710 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
6712 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
6713 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
6714 AT_CHECK_CALC_GLR_CC that are working now.
6716 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
6718 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
6719 We don't need them in glr.cc, and glr.c defines them.
6720 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
6721 assumes that defining it to anything is the same as defining
6722 it to 1. Problem reported by Paolo Bonzini.
6724 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
6726 * data/c.m4 (b4_null, b4_case): Define.
6727 * src/output.c (prepare_symbols): Use b4_null.
6728 (user_actions_output): Use b4_case.
6730 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
6732 * data/glr.c (b4_shared_declarations): Put start-header first,
6733 before any #includes that we generate, so that feature-test
6734 macros work. Problem reported by Michael Deutschmann in
6735 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
6736 * data/lalr1.cc: Likewise.
6737 * doc/bison.texinfo (Prologue): Document that feature-test macros
6738 should be defined before any Bison declarations.
6739 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
6740 that depend on location.hh after, not before, Bison decls, since
6741 we now include location.hh after the first user prologue.
6743 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
6744 Sander Brandenburg in
6745 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
6746 Also, fix minor white space and comment issues.
6747 (Prologue): Mention that it's better to define feature-test macros
6748 before Bison declarations. Problem reported by Michael Deutschmann.
6750 * README-cvs: Fix typo: "&" should be "&&". Problem reported
6752 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
6753 This adjusts to recent gnulib changes.
6755 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6757 Finish implementation of per-type %destructor/%printer. Discussed

6761 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
6762 * NEWS (2.3+): Add a description of this feature to the default
6763 %destructor/%printer description.
6764 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
6765 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6766 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
6767 list node contains a semantic type.
6768 * src/symtab.c, src/symtab.h: Extend with a table that associates
6769 semantic types with their %destructor's and %printer's.
6770 (semantic_type_from_uniqstr, semantic_type_get,
6771 semantic_type_destructor_set, semantic_type_printer_set): New functions
6772 composing the public interface of that table.
6773 (symbol_destructor_get, symbol_destructor_location_get,
6774 symbol_printer_get, symbol_printer_location_get): If there's no
6775 per-symbol %destructor/%printer, look up the per-type before trying
6777 * tests/actions.at (Per-type %printer and %destructor): New test case.
6778 * tests/input.at (Default %printer and %destructor redeclared):
6779 Extend to check that multiple occurrences of %symbol-default in a
6780 single %destructor/%printer declaration is an error.
6781 (Per-type %printer and %destructor redeclared, Unused values with
6782 per-type %destructor): New test cases.
6784 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6786 Require default %destructor/%printer to be declared using
6787 %symbol-default instead of an empty symbol list, and start working on
6788 new per-type %destructor/%printer. Discussed at
6789 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
6790 * NEWS (2.3+): Add %symbol-default to example.
6791 * bison.texinfo (Freeing Discarded Symbols): Likewise.
6792 (Table of Symbols): Add entry for %symbol-default.
6793 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
6794 (generic_symlist, generic_symlist_item): New nonterminals for creating
6795 a list in which each item is a symbol, semantic type, or
6797 (grammar_declaration): Use generic_symlist in %destructor and %printer
6798 declarations instead of symbols.1 or an empty list.
6799 (symbol_declaration, precedence_declaration, symbols.1): Update actions
6800 for changes to symbol_list.
6801 * src/reader.c: Update for changes to symbol_list.
6802 * src/scan-code.l: Likewise.
6803 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
6804 * src/symlist.c, src/symlist.h: Extend such that a list node may
6805 represent a semantic type or a %symbol-default in addition to just an
6806 ordinary symbol. Add switched functions for setting %destructor's and
6808 * tests/actions.at, tests/input.at: Add %symbol-default to all default
6809 %destructor/%printer declarations.
6811 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
6813 Whether the default %destructor/%printer applies to a particular symbol
6814 isn't a question of whether the user *declares* that symbol (in %token,
6815 for example). It's a question of whether the user by any means
6816 *defines* the symbol at all (by simply using a char token, for
6817 example). $end is defined by Bison whereas any other token with token
6818 number 0 is defined by the user. The error token is always defined by
6819 Bison regardless of whether the user declares it with %token, but we
6820 may one day let the user define error as a nonterminal instead.
6821 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6822 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
6823 the meaning of "user-defined".
6824 * tests/actions.at (Default %printer and %destructor for user-declared
6825 end token): Rename to...
6826 (Default %printer and %destructor for user-defined end token): ...
6829 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
6830 computation of whether to apply the default, don't maintain a list of
6831 every Bison-defined symbol. Instead, just check for a first character
6832 of '$', which a user symbol cannot have, and check for the error token.
6834 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
6836 Don't apply the default %destructor or %printer to the error token,
6837 $undefined, or $accept. This change fits the general rule that the
6838 default %destructor and %printer are only for user-declared symbols,
6839 and it solves several difficulties that are described in the new test
6841 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
6842 * tests/actions.at (Default %printer and %destructor are not for error
6843 or $undefined, Default %printer and %destructor are not for $accept):
6846 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
6848 Allow %start after the first rule.
6849 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
6850 when parsing the first rule.
6851 (check_and_convert_grammar): Search for it here after all grammar
6852 declarations have been parsed. Skip midrules, which have dummy LHS
6854 * src/symtab.c (symbol_is_dummy): New function.
6855 * src/symtab.h (symbol_is_dummy): Declare it.
6856 * tests/input.at (%start after first rule): New test.
6858 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6860 Redo some of the previous commit: add back the ability to use
6861 non-aliased/undeclared string literals since it might be useful to
6862 those declaring %token-table.
6863 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6864 commit: don't worry about complaints from symbols_pack.
6865 * src/symtab.c (symbol_new, symbol_class_set,
6866 symbol_check_alias_consistency): Undo changes in previous commit: count
6867 each string literal as a new symbol and token, assign it a symbol
6868 number, and don't complain about non-aliased string literals.
6869 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6870 and token counts but does still set aliased tokens to the same number,
6871 symbol_pack_processor now leaves empty slots in the symbols array.
6873 * tests/regression.at (Undeclared string literal): Remove test case
6874 added in previous commit since non-aliased string literals are allowed
6876 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6877 remove unnecessary string literal declarations.
6878 * tests/sets.at (Firsts): Likewise.
6880 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6882 Don't allow an undeclared string literal, but allow a string literal to
6883 be used before its declaration.
6884 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6885 symbols_pack complained.
6886 * src/symtab.c (symbol_new): Don't count a string literal as a new
6888 (symbol_class_set): Don't count a string literal as a new token, and
6889 don't assign it a symbol number since symbol_make_alias does that.
6890 (symbol_make_alias): It's not necessary to decrement the symbol and
6891 token counts anymore. Don't assume that an alias declaration occurs
6892 before any uses of the identifier or string, and thus don't assert that
6893 one of them has the highest symbol number so far.
6894 (symbol_check_alias_consistency): Complain if there's a string literal
6895 that wasn't declared as an alias.
6896 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6897 symbol_pack asserts that every token has been assigned a symbol number
6898 although undeclared string literals have not.
6899 * tests/regression.at (String alias declared after use, Undeclared
6900 string literal): New test cases.
6901 (Characters Escapes, Web2c Actions): Declare string literals as
6903 * tests/sets.at (Firsts): Likewise.
6905 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6907 In the grammar scanner, STRING_FINISH unclosed constructs and return
6908 them to the parser in order to improve error messages.
6909 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6910 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6911 * tests/input.at (Unclosed constructs): New test case.
6912 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6915 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6918 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6920 Handle string aliases for character tokens correctly.
6921 * src/symtab.c (symbol_user_token_number_set): If the token has an
6922 alias, check and set its alias's user token number instead of its own,
6923 which is set to indicate the alias. Previously, every occurrence of
6924 the character token in the grammar overwrote that alias indicator with
6926 * tests/input.at (String aliases for character tokens): New test.
6928 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6930 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6932 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6934 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6935 to prevent failures when building on older platforms.
6936 Check for autopoint failure.
6937 Set XGETTEXT_OPTIONS to values that check for C format strings,
6938 so that translators are warned about them (this also helps
6939 prevent core dumps).
6941 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6942 function, since it simplifies our code a bit.
6944 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6945 rather than -W, so we don't get bogus warnings about sign comparisons.
6946 Add -Wpointer-arith, since that warning is useful (it reports code
6947 that does not conform to C89 and that some compilers reject).
6948 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6949 since it's no longer needed.
6951 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6953 Clean up scanners a bit.
6954 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6955 definitions so gcc won't warn when obstack_for_string is unused.
6956 * src/scan-code.l: config.h and system.h are already #include'd by
6957 scan-code-c.c, so get rid of them here.
6958 * src/scan-gram.l: Likewise.
6959 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6960 definitions rather than duplicating the rest of it.
6961 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6963 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6965 Suppress signed/unsigned comparison warnings for yycheck.
6966 * data/c.m4 (b4_safest_int_type): New macro.
6967 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6968 a signed int type, cast it to b4_safest_int_type first.
6969 * data/yacc.c: Likewise.
6970 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6973 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6975 * doc/bison.texinfo: Fix some typos.
6977 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6979 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6980 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6982 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6983 the latest gnulib does this a different way.
6984 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6985 translation was patched, so stop omitting it.
6987 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6989 Enable declaration of default %printer/%destructor. Make the parser
6990 use these for all user-declared grammar symbols for which the user does
6991 not declare a specific %printer/%destructor. Thus, the parser uses it
6992 for token 0 if the user declares it but not if Bison generates it as
6993 $end. Discussed starting at
6994 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6995 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6997 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6998 * NEWS (2.3+): Mention.
6999 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
7000 declare a %destructor for a mid-rule's semantic value. It's just
7001 impossible to declare one specific to it.
7002 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
7003 code. Describe default %destructor form.
7004 * src/parse-gram.y (grammar_declaration): Parse default
7005 %printer/%destructor declarations.
7006 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
7007 and symbol_destructor_location_get rather than accessing the destructor
7008 and destructor_location members of struct symbol.
7009 (symbol_printers_output): Likewise but for %printer's.
7010 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
7012 * src/symtab.c (default_destructor, default_destructor_location,
7013 default_printer, default_printer_location): New static global
7014 variables to record the default %destructor and %printer.
7015 (symbol_destructor_get, symbol_destructor_location_get,
7016 symbol_printer_get, symbol_printer_location_get): New functions to
7017 compute the appropriate %destructor and %printer for a symbol.
7018 (default_destructor_set, default_printer_set): New functions to set the
7019 default %destructor and %printer.
7020 * src/symtab.h: Prototype all those new functions.
7021 * tests/actions.at (Default %printer and %destructor): New test to
7022 check that the right %printer and %destructor are called, that they're
7023 not called for $end, and that $$ and @$ work correctly.
7024 (Default %printer and %destructor for user-declared end token): New
7025 test to check that the default %printer and %destructor are called for
7026 a user-declared end token.
7027 * tests/input.at (Default %printer and %destructor redeclared, Unused
7028 values with default %destructor): New tests to check related grammar
7029 warnings and errors.
7031 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
7033 Clean up handling of %destructor for the end token (token 0).
7034 Discussed starting at
7035 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
7037 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
7039 Make the skeletons consistent in how they pop the end token and invoke
7041 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
7042 state, which has token number 0, since this would invoke the
7043 %destructor for the end token.
7044 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
7045 until after shifting the end token, or else it won't be popped.
7046 * data/yacc.c (yyparse): Likewise.
7048 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
7049 it's the end token. Upon termination, destroy an unshifted lookahead
7050 even when it's the end token.
7051 * data/lalr1.cc (yy::parser::parse): Likewise.
7052 * data/yacc.c (yyparse): Likewise.
7054 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
7055 value warnings for the end token when the user gives the end token a
7058 * tests/actions.at (Printers and Destructors): Test all the above.
7060 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
7062 Update to latest gnulib and gettext versions.
7063 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
7065 (gnulib_files): Add m4/warning.m4. Don't worry about files
7066 overwritten by autopoint.
7067 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
7068 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
7070 Don't use autoreconf; instead, invoke autopoint etc. by hand,
7071 so that we can remove the intl files at a better time.
7072 (intl_files_to_remove): Remove aclocal.m4, since it gets
7073 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
7074 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
7075 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
7076 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
7077 Remove datarootdir hack; no longer needed.
7078 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
7079 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
7080 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
7082 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
7083 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
7085 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7087 * bootstrap: Adjust to today's change to gnulib-tool by invoking
7088 it with --assume-autoconf='latest-stable'.
7090 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
7092 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
7093 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
7095 * src/muscle_tab.h (muscle_grow): Replace the header comments with
7096 those from muscle_tab.c since the old ones are misleading.
7098 2006-07-13 Akim Demaille <akim@epita.fr>
7100 Support %define "KEY" {VALUE}.
7101 * src/scan-code.h, src/scan-code.l (translate_action)
7102 (translate_rule_action, translate_symbol_action, translate_code):
7103 Return char *, not const char *.
7104 * src/parse-gram.y (declaration): Rename as...
7105 (prologue_declaration): this.
7106 (string_content): Remove this nonterminal, use STRING.
7107 (braceless, content, content.opt): New nonterminal.
7109 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
7111 * src/scan-gram.l (getargs.h): Don't include it.
7113 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
7115 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
7116 rather than a for-loop that declares a local bool variable. This
7117 should work around a compatibility problem with a Cray x1e C++
7118 compiler reported by Hung Nguyen in
7119 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
7120 The for-loop was introduced in the 2004-11-17 change but I don't
7121 know why it was needed.
7123 2006-07-12 Akim Demaille <akim@epita.fr>
7125 * data/c.m4: Comment changes.
7127 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
7129 * src/complain.c (error_message, ERROR_MESSAGE): New.
7131 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
7132 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
7134 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
7136 * NEWS: Instead of %union, you can define and use your own union type
7137 YYSTYPE if your grammar contains at least one <type> tag.
7138 Your YYSTYPE need not be a macro; it can be a typedef.
7139 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
7140 (Union Decl, Decl Summary): Document this.
7141 * data/glr.c (YYSTYPE): Implement this.
7142 * data/glr.cc (YYSTYPE): Likewise.
7143 * data/lalr1.cc (YYSTYPE): Likewise.
7144 * data/yacc.c (YYSTYPE): Likewise.
7145 * src/output.c (prepare): Output tag_seen_flag.
7146 * src/parse-gram.y (declaration, grammar_declaration):
7147 Use 'union_seen' rather than 'typed' to determine whether
7148 %union has been seen, since grammars can now be typed without
7150 (symbol_declaration, type.opt, symbol_def):
7151 Keep track of whether a tag has been seen.
7152 * src/reader.c (union_seen, tag_seen): New vars.
7154 * src/reader.h (union_seen, tag_seen, typed): Likewise.
7155 * src/scan-code.l (untyped_var_seen): New variable.
7156 (handle_action_dollar): Adjust to above changes.
7157 (handle_action_dollar, handle_action_at):
7158 Improve overflow checking for outlandish numbers.
7159 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
7160 avoid new diagnostics generated by above changes.
7161 * tests/regression.at (YYSTYPE typedef): Add test to check
7162 for type tags without %union.
7164 * src/symlist.c (symbol_list_length): Return int, not unsigned
7165 int, since callers expect int. This may need to get revisited
7166 once we have proper integer overflow checking.
7168 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
7169 object is now static.
7171 * src/getargs.c (flags_argmatch): Return void, not int,
7172 to pacify ./configure --enable-gcc-warnings.
7174 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
7175 since last_string is already defined to FLEX_PREFIX (last_string).
7177 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
7179 Implement --warnings/-W.
7180 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
7182 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
7184 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
7185 (warnings_args, warnings_types): New.
7186 (getargs, short_options, long_options): Accept -W/--warnings.
7187 Sort the options by alphabetical order, upper case letter right
7188 before its lower case.
7190 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
7192 Change %merge result type clash warnings to errors. Discussed at
7193 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
7194 * src/reader.c (record_merge_function_type): Use complain_at.
7195 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7196 declared later): Update test case results.
7198 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
7200 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
7201 to be in alphabetical order.
7202 (trace_args): Spelling fixes.
7204 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
7206 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
7207 so they don't collide with user-defined macros.
7208 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
7209 this was never guaranteed, and now that we're using gnulib stdint,
7210 which defines int_fast16_t to long int, the problem is exposed.
7212 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
7214 * data/c.m4 (b4_basename): Simplify a bit, since we don't
7215 need the full POSIX semantics (and weren't implementing them
7218 Adjust to Autoconf 2.60 and today's gnulib.
7219 * bootstrap (gnulib_modules): Add stdint.
7220 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
7221 no longer copies it.
7222 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
7223 since stdint needs the former and wcwidth (which is now required
7224 by mbswidth) needs the latter.
7225 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
7226 work around a compatibility glitch between gettext 0.14.6 and
7228 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
7229 Do not check for uintptr_t, since new stdint module does the right
7231 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
7232 Add stdint.h, stdint_.h, wcwidth.h.
7233 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
7234 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
7235 stdint.m4, wchar_t.m4, wcwidth.m4.
7236 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
7237 usual order for ../lib/*.h files.
7238 (file_name_split): Use last_component, not base_name, to adjust
7240 * src/parse-gram.h: Include <strverscmp.h> in the usual order
7241 for ../lib/*.h files.
7242 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
7243 Define unconditionally, since we now assume the stdint module.
7244 * src/scan-skel.l: Include <dirname.h>.
7245 (BASE_QPUTS): Use last_component, not base_name.
7246 * src/system.h: Include <unlocked-io.h> in the usual order
7247 for ../lib/*.h files. Include <stdint.h> unconditionally,
7248 since we now use the stdint module.
7249 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
7250 HAVE_UINTPTR_T, since we now use the stdint module.
7251 (base_name): Remove decl, since files now include <dirname.h>
7254 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
7256 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
7258 * data/yacc.c, data/glr.c, data/location.cc: Use them.
7259 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
7261 * tests/calc.at: Adjust.
7263 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
7265 * data/c.m4 (b4_basename): New.
7266 (b4_syncline): Also output the location of its invocation (from
7268 (b4_user_action, b4_define_user_action, b4_user_actions)
7269 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
7270 (b4_user_stype): New.
7271 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
7273 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
7275 In the grammar file, the first column is 1 not 0 on the first line as
7276 on every other line.
7277 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
7278 * tests/input.at (Torturing the Scanner): Update output.
7280 * src/scan-gram.l (scanner_cursor): Declare it static.
7282 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
7284 In warnings, say "previous declaration" rather than "first
7286 * src/symtab.c (redeclaration): Do that here.
7287 * src/reader.c (record_merge_function_type): In the case of a result
7288 type clash, report the previous declaration rather than the very first
7289 one in the grammar file.
7290 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7291 declared later): Add a third declaration to check this behavior.
7292 * tests/input.at (Incompatible Aliases): Update output.
7294 2006-06-27 Akim Demaille <akim@epita.fr>
7296 * doc/Doxyfile.in: New.
7297 * doc/Makefile.am: Use it.
7298 * src/lalr.h, src/symtab.h: Initial doxygenation.
7300 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7302 Don't miss %merge result type warnings just because the LHS types are
7303 declared after the %merge. This continues the effort of the previous
7305 * src/reader.c (get_merge_function): Don't set the merger type yet.
7306 (record_merge_function_type): New function for setting the merger type
7307 and checking for clashes.
7308 (grammar_current_rule_merge_set): Set the location of the %merge for
7310 (packgram): Invoke record_merge_function_type for each rule now that
7311 all symbol type declarations have been parsed.
7312 * src/reader.h (merger_list.type_declaration_location): New member
7313 storing the location of the first %merge from which the type for this
7314 merging function was derived.
7315 * src/symlist.h (symbol_list.merger_declaration_location): New member
7316 storing the location of a rule's %merge, if any.
7317 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7318 declared later): New test to catch the error fixed by the above patch.
7320 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7322 Get action warnings (grammar_rule_check) right even when symbol
7323 declarations appear after the rules. Discussed at
7324 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
7326 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
7327 Don't mistake the type of $$ in a midrule to be that of its parent
7329 * src/reader.c (grammar_current_rule_end): Don't invoke
7330 grammar_rule_check yet since not all symbol declarations may have been
7332 (grammar_midrule_action): Likewise.
7333 Don't record whether the midrule's $$ has been used yet since actions
7334 haven't been translated yet.
7335 Record the midrule's parent rule and its RHS index within the parent
7337 (grammar_current_rule_action_append): Don't translate the action yet
7338 since not all symbol declarations may have been parsed yet and, thus,
7339 warnings about types for $$, $n, @$, and @n can't be reported yet.
7340 (packgram): Translate the action and invoke grammar_rule_check now that
7341 all symbol declarations have been parsed.
7342 * src/scan-code.l (handle_action_dollar): Now that this is invoked
7343 after parsing the entire grammar file, the symbol list here in the case
7344 of a midrule is actually the midrule's empty RHS, so reference its
7345 parent rule's RHS where necessary.
7346 On the other hand, now that you can already know it's a midrule, you
7347 aren't forced to think $$ has the same type as its parent rule's $$.
7348 (handle_action_at): In the case of a midrule, reference the parent rule
7350 * src/symlist.c (symbol_list_new): Initialize new midrule-related
7352 (symbol_list_length): Now that this is invoked after all rules have
7353 been parsed, a NULL symbol (rather than a NULL symbol list node)
7354 terminates a rule. symbol_list_print already does this correctly.
7355 * src/symlist.h (symbol_list.midrule_parent_rule,
7356 symbol_list.midrule_parent_rhs_index): New members so that midrules can
7357 remember their relationships with their parents.
7358 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
7359 fixed by the above patch.
7360 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
7362 (Unused values): ... this old test case and...
7363 (Unused values before symbol declarations): ... this new test case.
7364 This one is the same as `Unused values' except that all symbol
7365 declarations appear after the rules in order to catch the rest of the
7366 errors fixed by the above patch.
7368 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7371 * src/reader.c (current_rule): Declare it static since it's no longer
7372 used outside this file.
7373 (grammar_current_rule_action_append): Remove redundant arguments from
7374 translate_rule_action invocation.
7375 * src/reader.h (current_rule): Remove this unused extern.
7376 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
7377 * src/scan-code.l (translate_rule_action): Likewise.
7379 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
7381 Clean up yesterday's patch.
7382 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
7384 * src/reader.c (grammar_current_rule_action_append): ... here for
7385 consistency with grammar_current_rule_symbol_append.
7386 * tests/regression.at (Braced code in declaration in rules section):
7387 Make yyerror and yylex static as usual.
7389 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
7391 Fix bug that mistakes braced code in a declaration in the rules section
7392 to be a rule action. Mentioned at
7393 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
7394 * src/scan-gram.l: Move midrule action detection from the start of the
7395 scanning of any braced code to...
7396 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
7397 action. For readability, use $2 and @2 rather than the equivalent
7399 * tests/regression.at (Braced code in declaration in rules section):
7400 New test to catch the error fixed by the above patch.
7402 Work on code readability some.
7403 * src/scan-code.l (current_rule): Get rid of this misleading and
7404 redundant declaration: it's actually extern'ed in reader.h.
7405 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
7406 translate_action): Add a rule argument and use it instead of the global
7408 (translate_rule_action): This already receives current_rule through an
7409 argument, so pass it on to translate_action instead of assigning
7410 current_rule to current_rule.
7411 (translate_symbol_action, translate_code): Pass rule = NULL to
7414 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
7416 Rename %before-definitions to %start-header and %after-definitions to
7417 %end-header. Don't use these declarations to separate pre-prologue
7418 blocks from post-prologue blocks. Add new order-independent
7419 declarations %before-header and %after-header as alternatives to the
7420 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
7421 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
7422 * NEWS (2.3+): Update for these changes.
7423 * data/glr.c (b4_before_definitions): Update to...
7424 (b4_start_header): ... this.
7425 (b4_after_definitions): Update to...
7426 (b4_end_header): ... this.
7427 * data/glr.cc: Likewise.
7428 * data/lalr1.cc: Likewise.
7429 * data/yacc.c: Likewise.
7430 * doc/bison.texinfo (The prologue): Update names, and replace remaining
7431 prologue blocks with %*-header declarations.
7432 (Calc++ Parser): Likewise.
7433 (Decl Summary): Update names.
7434 (Table of Symbols): Update description.
7435 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
7436 (PERCENT_END_HEADER): ... this.
7437 (PERCENT_BEFORE_DEFINITIONS): Update to...
7438 (PERCENT_START_HEADER): ... this.
7439 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
7440 (declaration): Update token names and m4 macro names.
7441 When parsing %end-header and %start-header, invoke translate_code
7442 before muscle_code_grow, and no longer set global booleans to remember
7443 whether these declarations have been seen.
7444 Parse new %after-header and %before-header.
7445 * src/reader.c (before_definitions, after_definitions): Remove.
7446 (prologue_augment): Accept a new bool argument to specify whether to
7447 augment the pre-prologue or post-prologue.
7448 * src/reader.h (before_definitions, after_definitions): Remove these
7450 (prologue_augment): Add new bool argument.
7451 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
7452 (PERCENT_END_HEADER): ... this.
7453 (PERCENT_BEFORE_DEFINITIONS): Update to...
7454 (PERCENT_START_HEADER): ... this.
7455 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
7456 * tests/actions.at (Printers and Destructors): Update names.
7458 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
7460 Add comparison operators for C++ location classes. Discussed at
7461 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
7462 * data/c++.m4 (b4_define_location_comparison): New boolean %define
7463 declaration indicating whether filename_type has an operator==. If
7464 filename_type is `std::string', it defaults to `1', `0' otherwise.
7465 * data/location.cc: Iff b4_define_location_comparison is `1', add
7466 operator== and operator!= for class position and for class location.
7469 * src/scan-action.l: Remove unused file.
7470 * src/symtab.c (symbol_printer_set): Use printer_location not
7471 destructor_location.
7472 * src/symtab.h (struct symbol): Replace incorrect source comment for
7474 * tests/input.at (Incompatible Aliases): Update output with correct
7477 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
7479 Don't put the pre-prologue in the header file. For the yacc.c code
7480 file and the glr.c header and code files, move the pre-prologue before
7481 the token definitions. Add new %before-definitions and
7482 %after-definitions to declare code that will go in both the header file
7483 and code file. Discussed at
7484 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
7485 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
7487 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
7488 * NEWS (2.3+): Describe these changes.
7489 * data/glr.c (b4_pre_prologue): Move from within to before...
7490 (b4_shared_declarations): ... this.
7491 Add new b4_before_definitions before b4_token_enums.
7492 Add new b4_after_definitions at the end.
7493 * data/glr.cc (b4_pre_prologue): Replace with...
7494 (b4_before_definitions): ... this in the header file.
7495 (b4_after_definitions): New near the end of the header file.
7496 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
7497 code file right before including the header file.
7498 (b4_before_definitions): New in the previous position of
7499 b4_pre_prologue in the header file.
7500 (b4_after_definitions): New near the end of the header file.
7501 * data/yacc.c: Clean up some m4 quoting especially in the header file.
7502 (b4_token_enums_defines): In the code file, move to right before
7503 YYSTYPE for consistency with the header file.
7504 (b4_before_definitions): New right before b4_token_enums_defines in
7505 both the header and code file.
7506 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
7507 header and code file.
7508 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
7509 of prologues for %union dependencies.
7510 (Decl Summary): In %defines description, mention the effect of
7511 %before-definitions and %after-definitions on the header file.
7512 (Calc++ Parser): Forward declare driver in a %before-definitions rather
7513 than in the pre-prologue so that make check succeeds.
7514 (Table of Symbols): Add entries for %before-definitions and
7516 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
7517 %before-definitions.
7518 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
7519 (declaration): Parse those declarations and append to
7520 b4_before_definitions and b4_after_definitions, respectively.
7521 * src/reader.c (before_definitions, after_definitions): New bools to
7522 track whether those declarations have been seen.
7523 (prologue_augment): Add to the post-prologue if %union,
7524 %before-definitions, or %after-definitions has been seen.
7525 * src/reader.h (before_definitions, after_definitions): New extern's.
7526 * src/scan-gram.l: Scan the new declarations.
7527 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
7528 prologue block in a %before-definitions or a %after-definitions based
7529 on whether the %union is declared.
7530 * tests/regression.at (Early token definitions with --yacc, Early token
7531 definitions without --yacc): Move tests for token definitions into the
7532 post-prologue since token names are no longer defined in the
7535 2006-06-20 Akim Demaille <akim@epita.fr>
7537 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
7538 (symbol_get): Use it.
7539 * src/parse-gram.y: Use it.
7541 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
7543 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
7544 build succeeds when configured with --enable-gcc-warnings.
7546 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7548 * src/parse-gram.y (char_name): New function.
7549 (CHAR, STRING, string_content): For %printer, properly escape.
7550 (ID): Prefer fputs to fprintf.
7551 (id): Reindent to be consistent with other rules.
7552 Properly quote char.
7554 The Translation Project changed its way of publishing translations
7555 to maintainers. I haven't received any responses to my request
7556 for supporting the old way, or for documenting the new way. I
7557 have modified 'bootstrap' to use screen scraping
7558 (in this case, HTML scraping). This is unreliable and inelegant,
7559 but I don't see any better way. Yuck.
7560 * bootstrap (TP_URL, WGET_COMMAND): New vars.
7561 (get_translations): New function, which uses HTML scraping to
7562 deduce locations of latest translations.
7563 Use this function to grab both bison and bison-runtime .po files.
7564 Don't bother priming the pump for the runtime-po domain any more,
7565 as it's now translated better than bison is.
7567 2006-06-19 Akim Demaille <akim@epita.fr>
7569 * src/scan-gram.l: No longer "parse" things after `%union' until
7570 `{'. Rather, return a single "%union" token.
7571 No longer make symbols: return strings, and leave the conversion
7572 to symbols to the parser.
7573 (SC_PRE_CODE, token_type): Remove.
7574 * src/parse-gram.y (%union): New field `character'.
7577 (ID, ID_COLON): Now that the scanner no longer makes them
7578 identifiers, adjust all uses to invoke symbol_get.
7579 (id_colon): New, wraps the conversion from string to symbol.
7580 (%union): Accept a possible union_name.
7581 (symbol): Now can be a char.
7582 * data/c.m4 (b4_union_name): Leave a default value.
7583 * data/glr.c, data/yacc.c: Use it.
7585 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
7587 For associating token numbers with token names for "yacc.c", don't use
7588 #define statements unless `--yacc' is specified; always use enum
7589 yytokentype. Most important discussions start at:
7590 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
7591 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
7593 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
7594 * NEWS (2.3+): Mention.
7595 * data/c.m4 (b4_yacc_if): New.
7596 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
7598 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
7599 on token name definitions.
7600 * src/getargs.c (usage): Capitalize `Yacc' in English.
7601 * src/output.c (prepare): Define b4_yacc_flag.
7602 * tests/regression.at (Early token definitions): Test that tokens names
7603 are defined before the pre-prologue not just before the post-prologue.
7604 Remove this test case and copy to...
7605 (Early token definitions with --yacc): ... this to test #define's.
7606 (Early token definitions without --yacc): ... and this to test enums.
7608 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
7610 * NEWS: Reword the post-2.3 change to not be so optimistic about
7611 removing the old "look-ahead" spelling.
7612 Update previous look-ahead/lookahead change reports.
7613 * REFERENCES: look-ahead -> lookahead (since that's
7614 what he actually wrote).
7615 * doc/refcard.tex: look ahead -> lookahead,
7616 look-ahead -> lookahead
7618 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
7620 For consistency, use `lookahead' instead of `look-ahead' or
7621 `look_ahead'. Discussed starting at
7622 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
7624 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.
7625 * NEWS: For the next release, note the change to `--report'.
7626 * TODO, doc/bison.1: Update English.
7627 * doc/bison.texinfo: Update English.
7628 (Understanding Your Parser, Bison Options): Document as
7629 `--report=lookahead' rather than `--report=look-ahead'.
7630 * src/conflicts.c: Update English in comments.
7631 (lookahead_set): Rename from look_ahead_set.
7632 (flush_reduce): Rename argument look_ahead_tokens to lookahead_tokens.
7633 (resolve_sr_conflict): Rename local look_ahead_tokens to
7634 lookahead_tokens, and update other uses.
7635 (flush_shift, set_conflicts, conflicts_solve, count_sr_conflicts,
7636 count_rr_conflicts, conflicts_free): Update uses.
7637 * src/getargs.c (report_args): Move "lookahead" before alternate
7639 (report_types): Update uses.
7640 (usage): For `--report' usage description, state `lookahead' spelling

7695 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7697 * TODO: Add request from Nelson H. F. Beebe to be able to install
7698 Bison without installing the yacc script.
7700 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
7702 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
7703 and yytext if they're already #define'd.
7704 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...

7714 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
7715 loc argument as it shadows a global.
7716 * src/scan-gram.l: Remove stray comma that prevents boundary_set
7719 * src/.cvsignore: Add scan-code.c.
7721 2006-06-07 Akim Demaille <akim@epita.fr>
7723 * src/scan-gram.l: Move the "add a trailing ; to actions" code
7725 * src/scan-code.l: here.

7733 2006-06-06 Akim Demaille <akim@epita.fr>
7735 Extract the parsing of user actions from the grammar scanner.
7736 As a consequence, the relation between the grammar scanner and
7737 parser is much simpler. We can also split "composite tokens" back
7739 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
7740 * src/scan-gram.l (add_column_width, adjust_location): Move to and
7742 * src/location.h, src/location.c (add_column_width)
7743 (location_compute): these.
7744 Fix the column count: the initial column is 0.
7745 (location_print): Be robust to ending column being 0.
7746 * src/location.h (boundary_set): New.
7747 * src/main.c: Adjust to scanner_free being renamed as
7749 * src/output.c: Include scan-code.h.
7750 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
7752 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
7753 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
7754 which is now, again, a separate token.
7755 Adjust all dependencies.
7756 Whereever actions with $ and @ are used, use translate_code.
7757 (action): Remove this nonterminal which is now useless.
7758 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
7759 (grammar_current_rule_action_append): Use translate_code.

7777 (increment_rule_length): Remove.
7778 (last_braced_code_loc): Rename as...
7779 (gram_last_braced_code_loc): this.
7780 Adjust to the changes of the parser.
7781 Move all the handling of $ and @ into...
7782 * src/scan-code.l: here.
7783 * src/scan-gram.l (handle_dollar, handle_at): Remove.

7796 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7798 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7799 Use Akim's wording from
7800 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
7802 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7804 Between Bison releases, manually append `+' to the previous Bison
7805 release number, and use that as a signal to automatically print the
7806 ChangeLog's CVS Id keyword from --version. Discussed starting at
7807 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
7808 * ChangeLog: Add Id header.
7809 * configure.ac (AC_INIT): Append `+' to `2.3'.
7810 * src/.cvsignore: Add revision.c.
7811 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
7812 (BUILT_SOURCES): Add revision.c.
7813 (revision.c): New target rule. This file defines a new global variable
7814 named revision. It initializes it with either the Id from ChangeLog
7815 or, if VERSION doesn't contain `+', with the empty string.
7816 * src/getargs.c (version): Print the value of revision.
7817 * src/revision.h: Extern revision.
7819 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7821 * NEWS: Version 2.3.
7822 * configure.ac (AC_INIT): Likewise.
7824 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7826 * data/glr.c (YYRECOVERING): Define to be a function-like macro
7827 with no arguments, not as an object-like macro. This is for
7828 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
7829 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
7830 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
7833 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
7835 * src/getargs.c (usage): Back out yesterday's modification of the
7836 --help output so that we don't have to wait for translation before
7839 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7841 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
7842 Problem reported by Akim Demaille.
7844 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
7846 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7848 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7850 * data/yacc.c (yy_reduce_print): Omit trailing white space in
7851 generated source code. Problem reported by Frans Englich in
7852 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7854 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7856 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7857 shell, not within 'make', so that 'make' by an ordinary builder
7858 (using GNU make) does not worry about configuring gzip. This also
7859 works around a bug reported independently by Keith Thompson and by
7860 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7861 stderr rather than stdout, messing up the build logs.
7863 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7865 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7866 to make sure that YYID will never be unused. This fixes a 'make
7867 maintainer-check' failure caused by the recent changes to the 'Trivial
7868 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7870 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7872 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7874 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7875 state before an empty RHS is always resolved here. Only the location
7876 of that state is guaranteed to be resolved, and that's enough. This
7877 fixes the remaining bug reported by Derek M. Jones in
7878 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7879 * tests/glr-regression.at (Uninitialized location when reporting
7880 ambiguity): Test the above case.
7881 Also, the embedded comments in this test case claim it checks the case
7882 of an empty RHS that has inherited the initial location. However, the
7883 corresponding LHS was already resolved, so yyresolveLocations didn't
7884 actually have reason to modify it. Fix this by forcing
7885 nondeterministic operation at the beginning of the parse.
7887 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7889 * data/c.m4 (b4_yy_symbol_print_generate):
7890 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7891 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7892 of the bugs reported today by Derek M Jones in
7893 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7894 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7895 defined to be a type name without parens or brackets.
7896 (Location Type): Similarly for YYLTYPE.
7897 * tests/regression.at (Trivial grammars): Put in a test for this
7898 bug that will be caught by 'make maintainer-check' (though not,
7899 alas, by 'make check' unless your compiler is picky).
7901 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
7903 * NEWS: Version 2.2.
7904 * configure.ac (AC_INIT): Likewise.
7906 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
7908 * data/glr.c (yyreportTree): Make room in yystates for the state
7909 preceding the RHS. This fixes the segmentation fault reported by Derek
7911 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7912 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7913 to the user. Reported for yyreportTree by Derek M. Jones later in the
7915 * THANKS: Add Derek M. Jones.
7916 Update my email address.
7917 Fix typo in Steve Murphy's name.
7919 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7921 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7922 checking against YYLAST that caused the parser to miss a potential
7923 alternative in its diagnostic.
7924 Problem reported by Maria Jose Moron Fernandez in
7925 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
7926 * data/lalr1.cc (yysyntax_error_): Likewise.
7927 * data/yacc.c (yysyntax_error): Likewise.
7928 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7929 tokens, in case we run into an older C compiler.
7930 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7931 Use them to check for the off-by-one error fixed above.
7933 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7934 YYSIZE_T, not size_t.
7935 * tests/regression.at (Trivial grammars): New test, to catch
7936 the error fixed by the above patch.
7938 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7940 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7942 Reported by Steve Murphy.
7944 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7946 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7947 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7949 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7951 Implement --trace=m4.
7952 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7953 * src/output.c (output_skeleton): When set, pass -dV to m4.
7955 Factor the handling of flags in m4.
7956 * src/output.c (prepare): Rename the muscle names debug, defines,
7957 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7958 * data/c.m4: Adjust.
7959 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7960 Use b4_define_flag_if to define other b4_FLAG_if macros.
7961 (b4_location_if): As a consequence, rename as...
7962 (b4_locations_if): this, for consistency.
7963 Adjust all the skeletons.
7965 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7967 * etc/bench.pm: Shorten bench names.
7969 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7971 * src/output.h, src/output.c (error_verbose): Move to...
7972 * src/getargs.h, src/getargs.c: here.
7974 Adjust dependencies.
7976 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7978 * data/c.m4 (b4_copyright): Put the special exception for Bison
7979 skeletons here, so we don't have to put it in each skeleton. All
7980 uses changed. Suggested by Akim Demaille. Also, wrap the
7981 copyright notice, in case it is longer than 80 columns. Replace
7982 comma by newline after title.
7984 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7986 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7987 incompatibility, not a bug. Mention that it wasn't fixed as of
7990 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7992 * examples/extexi: Enforce the precedence of concatenation over
7994 Reported by Tommy Nordgren.
7996 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7998 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7999 with the member "token".
8000 Reported by Martin Nylin.
8002 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
8004 * data/glr.c: Switch to Bison 2.2 special-exception language in
8005 the copyright notice. Use more-regular format for titles and
8007 * data/glr.cc: Likewise.
8008 * data/location.cc: Likewise.

8015 * data/glr.cc: Remove dead code.
8017 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8019 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
8020 that variable and the line breaks the bootstrap. Problem reported
8021 by Juan M. Guerrero.
8023 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
8025 * doc/bison.texinfo (Multiple start-symbols): New.

8038 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
8040 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
8041 Problem reported by Bob Rossi.
8043 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
8045 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
8046 and didn't really work.
8047 For the index, use @ifnotinfo, not @iftex.
8048 Minor cleanups of spacing and terminology.
8050 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
8052 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
8053 of AT_NAME_PREFIX when %name-prefix is not used.
8055 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
8057 Apply --prefix to C++ skeletons too: they change the namespace.
8058 The test suite already exercize these cases.
8059 * data/c++.m4 (b4_namespace): New.
8060 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
8061 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
8062 * data/yacc.c, data/glr.c: Remove a useless `[]'.
8063 * doc/bison.texinfo: Document it.
8064 (Option Cross Key): Use @multitable in all formats. It looks
8065 nicer, even in TeX outputs.
8066 (Rules): Use the same code whatever the output type is.
8067 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
8068 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
8069 * tests/calc.at: Use it, instead of hard coding `yy'.

8102 and "POSIX". Use more-modern syntax for URLs. Mention C++
8103 and ask for Java. Don't hardwire OS version numbers. Add

8106 * src/conflicts.c (solved_conflicts_obstack): Now static.
8108 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
8110 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
8111 page. Say "you can use it" not "you may use it" as on the web page;
8112 we're describing capabilities not granting permission.

8116 * data/glr.c (yyresolveLocations): Rename local variables to avoid
8117 shadowing warnings. Use usual patter for iterating through RHS.
8118 * tests/glr-regression.at
8119 (Uninitialized location when reporting ambiguity):
8120 Modify yylex so that it uses its argument, rather than trying
8121 to rely on ARGSUSED (which doesn't work for gcc with warnings).
8122 const char -> char const.
8124 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
8125 Don't use tabs inside commands; it messes up 'ps'.
8126 Problem reported by twlevo.
8128 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
8130 * tests/glr-regression.at (Uninitialized location when reporting
8131 ambiguity): New test case.
8132 * data/glr.c (yyresolveLocations): New function, which uses
8134 (yyresolveValue): Invoke yyresolveLocations before reporting an
8136 * doc/bison.texinfo (Default Action for Locations): Note
8137 YYLLOC_DEFAULT's usage for ambiguity locations.
8138 (GLR Semantic Actions): Cross-reference those notes.
8140 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
8142 * tests/glr-regression.at (Leaked semantic values when reporting
8143 ambiguity): Remove unnecessary union and type declarations.
8144 (Leaked lookahead after nondeterministic parse syntax error): New test
8146 * data/glr.c (yyparse): Check for zero stacks remaining before
8147 attempting to shift the lookahead so that you don't lose it.
8149 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
8151 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
8152 * tests/glr-regression.at (Leaked semantic values when reporting
8153 ambiguity): New test case.
8154 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
8155 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
8156 now unnecessary yystackp parameter.
8157 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
8158 destructors can be called.
8160 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
8161 in existing testcases.
8163 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
8165 Don't leak semantic values for parent RHS when a user action cuts the
8166 parser, and clean up related code a bit.
8167 * tests/glr-regression.at (Leaked merged semantic value if user action
8168 cuts parse): Rename to...
8169 (Leaked semantic values if user action cuts parse): ... this. Add check
8170 for leaked parent RHS values.
8171 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
8172 between an unresolved state (non-empty chain of semantic options) and
8173 an incomplete one (signaled by an empty chain).
8174 (yyresolveStates): Document the interface. Move all manipulation of a
8175 successfully or unsuccessfully resolved yyGLRState to...
8176 (yyresolveValue): ... here so that yyresolveValue always leaves a
8177 yyGLRState with consistent data and thus is easier to understand.
8178 Remove the yyvalp and yylocp parameters since they are always just
8179 taken from the yys parameter. When reporting a discarded merged value
8180 in debugging output, note that it is incompletely merged. Document the
8182 (yyresolveAction): If resolving any of the RHS states fails, destroy
8183 them all rather than leaking them. Thus, as long as user actions are
8184 written to clean up the RHS correctly, yyresolveAction always cleans up
8185 the RHS of a semantic option. Document the interface.

8195 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
8196 mid-rule action inside a nonterminal symbol in order to declare a
8197 destructor for its semantic value.

8206 declarations of malloc and free, to avoid problems with
8207 incompatible declarations (using 'throw') C++'s stdlib.h. This
8208 should fix Debian bug 340012

8248 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
8249 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
8251 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
8252 nodist_PROGRAMS, since we don't need to actually compile the
8253 example if we're just doing a plain 'make'. This avoids bothering
8254 the installer unnecessarily about problems due to weird C++

8261 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
8262 than #include "...", and compile with -I'.'. The old method was
8263 not portable, according to Posix and the C standard, and it does
8264 not work with Sun C 5.7, where previous #line directives affect
8265 the working directory used in later #include "..." directives.

8284 that '#include <string>' works.
8286 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
8287 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
8288 "warning: sorry: semantics of inline function static data `const
8289 unsigned char translate_table[262]' are wrong (you'll wind up with
8292 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
8293 or, xor to not_, and_, or_, and xor_, respectively. This works
8294 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
8295 random system header somewhere that includes the equivalent of

8304 During deterministic GLR operation, user actions should be able to
8305 influence the parse by changing yychar. To make this easier to fix and
8306 to make glr.c easier to evolve in general, don't maintain yytoken in
8307 parallel with yychar; just compute yytoken when needed.
8308 * tests/glr-regression.at (Incorrect lookahead during deterministic
8309 GLR): Check that setting yychar in a user action has the intended

8312 (yyclearin): Don't set *yytokenp.
8313 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
8314 yychar rather than *yytokenp to determine the current lookahead.
8315 Compute yytoken locally when needed.
8316 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
8319 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
8320 after `--report' documentation.

8334 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
8335 got from <http://bro-ids.org/download.html>. The bug is that
8336 when two actions appeared in succession, the second one was
8337 scanned before the first one was added to the grammar rule
8338 as a midrule action. Bison then output the incorrect warning
8339 "parse.y:905.17-906.36: warning: unused value: $3".
8340 * src/parse-gram.y (BRACED_CODE, action): These are no longer
8341 associated with a value.
8342 (rhs): Don't invoke grammar_current_rule_action_append.

8344 * src/reader.c (grammar_midrule_action): Now extern.
8345 (grammar_current_rule_action_append): Don't invoke
8346 grammar_midrule_action; that is now the scanner's job.

8348 (grammar_midrule_action): New decls.
8349 * src/scan-gram.l (last_string): Now extern, sigh.

8354 * tests/input.at (AT_CHECK_UNUSED_VALUES):
8355 Add some tests to check that the above changes fixed the bug.
8357 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
8359 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
8360 All used changed. Check whether the symbol has a destructor,
8361 not whether it is typed.
8362 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
8363 that the values are still reported as unused. All line numbers

8411 of the changelog every time.

8593 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
8595 * doc/bison.texinfo: Fix some typos.
8596 (GLR Semantic Actions): New subsection discussing special
8597 considerations because GLR semantic actions might be deferred.
8598 (Actions): Mention look-ahead usage of yylval.
8599 (Actions and Locations): Mention look-ahead usage of yylloc.
8600 (Special Features for Use in Actions): Add YYEOF entry and mention it
8601 in the yychar entry.
8602 In the yychar entry, remove mention of the local yychar case (pure
8603 parser) since this is irrelevant information when writing semantic
8604 actions and since it's already discussed in `Table of Symbols' where
8605 yychar is otherwise described as an external variable.
8606 In the yychar entry, don't call it the `current' look-ahead since it
8607 isn't when semantic actions are deferred.
8608 In the yychar and yyclearin entries, add note about deferred semantic
8610 Add yylloc and yylval entries discussing look-ahead usage.
8611 (Look-Ahead Tokens): When discussing yychar, don't call it the
8612 `current' look-ahead, and do mention yylval and yylloc.
8613 (Error Recovery): Cross-reference `Action Features' when mentioning
8615 (Table of Symbols): In the yychar entry, don't call it the `current'
8617 In the yylloc and yylval entries, mention look-ahead usage.

8621 * tests/glr-regression.at: Update copyright year to 2006.
8623 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
8625 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
8626 use during nondeterministic operation to track which stacks have
8627 actually needed the current lookahead.
8628 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
8629 Allocate, deallocate, resize, and otherwise shuffle space for
8630 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
8631 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
8632 appropriately during nondeterministic operation.
8633 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
8634 members to store the current lookahead to be used by the deferred
8636 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
8637 from which the RHS is taken. Set the lookahead members of the new
8638 yySemanticOption according to the lookahead status for stack yyk.
8639 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
8640 yyaddDeferredAction.
8641 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
8642 members of yySemanticOption before invoking yyuserAction, and then set

8647 titles for consistency.
8648 (Leaked merged semantic value if user action cuts parse): In order to
8649 suppress lint warnings, use arguments in merge function, and assign
8650 char value < 128 in main.
8651 (Incorrect lookahead during deterministic GLR): New test case.
8652 (Incorrect lookahead during nondeterministic GLR): New test case.
8654 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

8663 * tests/glr-regression.at: For consistency with my newer test cases,
8666 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
8668 * data/glr.c (yyresolveValue): When merging semantic options, if at
8669 least one user action succeeds but a later one cuts the parse, then
8670 destroy the semantic value before returning rather than leaking it.
8671 (yyresolveStates): If a user action cuts the parse and thus
8672 yyresolveValue fails, ignore the (unset) semantic value rather than
8673 corrupting the yyGLRState, and empty the semantic options list since
8674 the user actions should have called all necessary destructors.
8675 Simplify code with YYCHK.
8676 * tests/glr-regression.at (Corrupted semantic options if user action
8677 cuts parse): New test case.
8678 (Undesirable destructors if user action cuts parse): New test case.
8679 Before applying any of this patch, this test case never actually failed
8680 for me... but only because the corrupted semantic options usually

8724 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
8725 about declarations in the grammar when in Yacc mode, as POSIX does
8726 not require a diagnostic when the grammar uses extensions.
8728 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
8730 Warn about dubious constructions like "%token T T".
8732 * src/symtab.h (struct symbol.declared): New member.

8754 (b4_parse_param): Improve its definition, and bound it more
8755 clearly in the skeleton.
8756 (b4_epilogue): Append, instead of prepending, in order to keep
8758 Simplify the generation of auxiliary functions: locations and
8759 purity are mandated.
8760 (b4_global_tokens_and_yystype): Honor it.
8761 * data/location.cc (c++.m4): Don't include it.
8762 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
8764 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of

8799 (rule_length_overflow, increment_rule_length, add_column_width):
8801 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
8802 (<SC_BRACED_CODE>"}"):
8803 Use increment_rule_length rather than incrementing it by hand.
8804 (adjust_location, handle_syncline): Diagnose overflow.
8805 (handle_action_dollar, handle_action_at):
8806 Fix bug with monstrosities like $-2147483648.

8875 Undo 2005-12-01 tentative license wording change. The wording is
8876 still being reviewed by the lawyers, and we don't want to wait for

8899 * tests/cxx-type.at: Construct a tree, count the parents of shared
8900 nodes, and free each node once and only once. Previously, the memory
8901 for semantic values was leaked instead.
8903 2005-12-21 Joel E. Denny <address@hidden>
8905 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.

8920 `if (YYID (N))' to pacify lint.
8922 2005-12-21 Akim Demaille <akim@epita.fr>

8925 destroy the RHS symbols of a rule.
8926 * data/yacc.c (yylen): Initialize to 0.
8927 Keep its value to the number of items to possibly shift.
8928 In particular, a regular successful parse that ends on YYFINAL by
8929 a (internal) YYACCEPT must not have yylen != 0.
8930 (yyerrorlab, yyreturn): Pop the RHS.
8931 Reorder a bit to emphasize the `shifting' bits of code.

8943 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
8944 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
8945 * djgpp/config.sed: Replace every occurence of the file name
8946 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

8975 * tests/sets.at (Accept): Fix typos in regular expression used to
8976 sed out the final state number.
8978 Work around portability problem on Solaris 10: flex-generated
8979 files include <stdio.h> before <config.h>, which messes up
8980 because the latter defines __EXTENSIONS__. Address the problem
8981 by creating two new little files that include <config.h> first,
8982 then include the flex-generated files. Rewrite everyone else
8983 to include <config.h> first, as well.
8984 * lib/timevar.c: Always include "config.h".

9026 definition if 'lint' is defined.
9027 (YYID): New macro (or function, if lint).
9028 All uses of /*CONSTCOND*/0 replaced by YYID(0).
9029 * data/yacc.c: Likewise.
9030 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):

9032 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
9034 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
9035 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
9036 Use YYID(0) rather than 0, for lint.

9323 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
9325 Undo the parts of the unlocked-I/O change that substituted

9327 but some people prefer the printf style.

9358 Use unlocked I/O for a minor performance improvement on hosts like
9359 GNU/Linux and Solaris that support unlocked I/O. The basic idea

9532 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
9533 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
9534 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
9535 to match yacc.c, to test more hosts.
9537 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
9539 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
9540 doesn't affect behavior.
9541 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
9543 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
9544 This works a bit better with glibc, if user code has already included
9546 * doc/bison.texinfo (Bison Parser): Document that users can't
9547 arbitrarily use malloc and free for other purposes. Document
9548 that <alloca.h> and <malloc.h> might be included.
9549 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
9550 user must declare alloca.
9552 * HACKING (release): Forwarn the Translation Project about
9555 2005-09-20 Akim Demaille <akim@epita.fr>
9557 * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
9559 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
9561 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
9562 (YYSTACK_ALLOC_MAXIMUM): Use it.
9563 (yysyntax_error): New function.
9564 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
9565 multiple syntax errors are reported, and alloca is being used.
9566 Instead, reallocate buffers twice as big each time, so that
9567 we waste at most half the allocated memory. Start with a small
9568 (128-byte) buffer that will suffice in most cases anyway.
9569 Use yysyntax_error to do most of the work.
9571 * doc/bison.texinfo (Error Reporting, Table of Symbols):
9572 yynerrs is the number of errors reported, not the number of
9575 * tests/glr-regression.at (Duplicated user destructor for lookahead):
9576 Mark it as expected to fail.
9577 Cast result of malloc; problem reported by twlevo@xs4all.nl.
9578 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
9579 Don't start user-code symbols with "yy", to avoid name space problems.
9581 2005-09-19 Akim Demaille <akim@epita.fr>
9583 Remove the traits, failed experiment.
9584 It never proved useful, and anyway because of the current
9585 definition, it was not possible to have several specialization of
9586 this traits, making it useless.
9587 * data/lalr1.cc (yy:traits): Remove.
9588 Inline its definitions in the parser class.
9590 2005-09-19 Akim Demaille <akim@epita.fr>

9595 2005-09-19 Akim Demaille <akim@epita.fr>
9597 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
9598 and yytoken for similarity with the other skeletons.

9612 * src/output.c (prepare): Likewise.
9613 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
9614 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
9615 is not defined. This is an awful hack, but it's enough for now.
9616 All callers changed.
9617 * tests/glr-regression-at (make_value): Args are const pointers now,
9618 to avoid GCC warning.
9619 (Duplicated user destructor for lookahead): New test. Currently
9620 skipped. It fails on my host but I'm not sure it'll always fail.
9622 2005-09-16 Akim Demaille <akim@epita.fr>
9624 * src/symtab.h (struct symbol): Declare the printer and destructor
9625 as const, to avoid accidental calls to free.
9626 (symbol_destructor_set, symbol_printer_set): Adjust.
9627 * src/symtab.c: Adjust.
9629 2005-09-16 Akim Demaille <akim@epita.fr>
9631 * data/c.m4 (b4_token_enums): New.
9632 (b4_token_defines): Rename as...
9633 (b4_token_enums_defines): this.
9634 (b4_token_defines): New, output only the #defines.
9635 * data/yacc.c, data/glr.c: Adjust.
9636 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
9637 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
9640 2005-09-16 Akim Demaille <akim@epita.fr>
9642 * data/lalr1.cc (yylex_): Remove, inline its code.
9643 (yyreport_syntax_error_): Remove, replaced by...
9644 (yysyntax_error_): this which returns a string and leaves to the
9645 caller the call to the users' error function.
9646 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
9647 Move from members of the parser object...
9648 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
9649 to local variables of the parse function.
9651 2005-09-16 Akim Demaille <akim@epita.fr>
9653 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
9654 since it's in Bison's name space.
9656 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
9658 * data/glr.c (yyresolveValue): Add default case to pacify
9659 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
9661 * NEWS: Document when yyparse started to return 2.
9662 * doc/bison.texinfo (Parser Function): Document when yyparse
9665 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
9666 (b4_filename_type): Renamed back from b4_file_name_type. All uses
9668 (class position): file_name -> filename (reverting). All uses changed.
9670 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
9672 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
9673 do anything if $@ exists. This reverts part of the 2005-07-07
9676 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
9678 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
9679 contains obsolete information and isn't worth distributing as a
9680 separate file anyway.
9681 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
9682 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
9683 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
9684 (yyparse): Abort if user code uses longjmp to throw an unexpected
9687 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
9689 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
9690 Suggested by twlevo@xs4all.nl.
9692 * data/glr.c (YYCHK1): Do not assume YYE is in range.
9693 This avoids a diagnostic from gcc -Wswitch-enum.
9694 Problem reported by twlevo@xs4all.nl.
9696 * doc/bison.texinfo: Don't use "filename", as per GNU coding
9697 standards. Use "file name" or "file" or "name", depending on
9699 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
9700 not to hack/foo.tab.c.
9701 (Calc++ Top Level): 2nd arg of main is not const.
9702 * data/glr.c: b4_filename -> b4_file_name.
9703 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

9720 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
9722 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is

9727 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
9728 All uses changed. Invoke user destructor after an error during a
9729 split parse (trivial change from Joel E. Denny).
9731 * tests/glr-regression.at
9732 (User destructor after an error during a split parse): New test case.
9733 Problem reported by Joel E. Denny in:
9734 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
9736 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9738 * README-cvs: Give URLs for recommended tools.
9739 Mention Gzip version problem, and bootstrapping issues.
9740 Remove troubleshooting section, as it's somewhat obsolete.
9742 * bootstrap (no_cache): New var, to accommodate different wget
9743 variants. Use it instead of '-C off'. Problem reported by
9746 * data/glr.c (yydestroyStackItem): New function.
9747 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
9748 debugging information. Problem reported by Joel E. Denny.
9750 2005-08-25 Akim Demaille <akim@epita.fr>

9758 * tests/glr-regression.at
9759 (User destructor for unresolved GLR semantic value): New test case.
9760 Problem reported by Joel E. Denny in:
9761 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
9763 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
9765 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
9767 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
9768 lib-prefix.m4, po.m4.
9770 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
9771 in yydestruct diagnostic, since it might not be an error.
9772 Problem reported by Joel Denny near end of
9773 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9774 * data/lalr1.cc (yyerturn): Likewise.
9775 * data/yacc.c (yyreturn): Likewise.
9776 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
9778 * src/files.c: Remove obsolete FIXME comment.
9780 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
9781 with the other templates, and to fix bogus run-on messages such
9782 as the one reported at the end of
9783 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9784 All callers changed to avoid the newline.
9785 (yyprocessOneStack): Output two lines rather than one, to accommodate
9786 the above change. This changes the debug output format slightly.
9788 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
9789 reported by Joel E. Denny in
9790 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
9792 * tests/glr-regression.at (Duplicate representation of merged trees):
9793 New test, from Joel E. Denny in:

9797 * configure.ac (AC_INIT): Bump to 2.0c.
9799 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
9801 * NEWS: Version 2.0b.
9803 * Makefile.am (SUBDIRS): Put examples before tests, so that
9804 "make check" doesn't finish with "All 1 tests passed".
9806 * tests/regression.at (Token definitions): Don't rely on
9807 AT_PARSER_CHECK for data that contains backslashes. It currently
9808 uses 'echo', and 'echo' isn't portable if its argument contains
9809 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9810 that the byte '\0xff' is not printable in the C locale; it is,
9811 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9812 not printable, so use '\0x81' to test.
9814 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
9815 version of GCC, since the macro is used with non-GCC compilers.
9817 Fix core dump reported by Pablo De Napoli in
9818 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
9819 * tests/regression.at (Invalid inputs with {}): New test.
9820 * src/parse-gram.y (token_name): Translate type before using
9823 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
9824 the user's name space. All uses changed to __attribute__
9826 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
9827 Add __attribute__ ((__noreturn__)).
9829 * etc/clcommit: Remove. We weren't using it, and it failed
9830 "make maintainer-distcheck".
9831 * Makefile.maint: Merge from coreutils.
9832 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
9833 (syntax-check-rules): Change list of rules as described below.
9834 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

9842 (makefile-check, po-check, author_mark_check):
9843 (makefile_path_separator_check, copyright-check):
9844 Use grep -n, to make it easier to find violations.
9845 Use CVS_LIST and CVS_LIST_EXCEPT.
9846 (header_regexp, h_re): Remove.
9848 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
9849 (my-distcheck): Use more-modern GCC flags.
9850 (signatures, %.asc): Remove.
9851 (rel-files, announcement): Remove signatures.
9852 Restore old updating code, even though we don't use it, so
9853 that we're the same as coreutils.
9854 (alpha, beta, major): Depend on news-date-check.
9855 Make the upload commands.
9857 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
9858 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
9859 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.

9864 * tests/sets.at: Likewise.
9866 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9867 we comment out the Autoconf version number.
9868 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9869 it's error-prone and "make maintainer-distcheck" rejects it.
9871 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9872 Indent calls to "error" to pacify "make maintainer-distcheck",
9873 when the calls are not intended to be translated.
9874 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9876 * src/Makefile.am (DEFS): Use +=, to pacify
9877 "make maintainer-distcheck".
9878 (bison_SOURCES): Add scan-skel.h.
9879 (sc_tight_scope): New rule, from coreutils.
9881 * src/files.c (src_extension, header_extension):
9882 Now static, not extern.
9883 * src/getargs.c (short_options): Likewise.
9884 * src/muscle_tab.c (muscle_table): Likewise.
9885 * src/parse-gram.y (current_class, current_type, current_prec):
9887 * src/reader.c (grammar_end, previous_rule_end): Likewise.
9888 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9889 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9890 void, to avoid warning when NLS is disabled.
9891 * src/output.c: Include scan-skel.h.
9892 (scan_skel): Remove decl, since scan-skel.h does this.
9894 Indent calls to "error" to pacify "make maintainer-distcheck".
9895 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9896 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9897 "make maintainer-distcheck".
9898 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
9899 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
9900 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
9901 (skel_lex_destroy, scan_skel): Move these decls to...
9902 * src/scan-skel.h: New file.
9903 * src/uniqstr.c (uniqstr_assert):
9904 Indent calls to "error" to pacify "make maintainer-distcheck".
9906 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9909 * tests/torture.at: Revamp to avoid misuse of atoi that
9910 "make maintainer-distcheck" complained about.
9912 * examples/extexi (message): Don't print a message more than once,
9913 and omit line-number decoration that makes Emacs compile think
9914 that informative messages are worth worrying about.
9916 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9918 * configure.ac: Update version number.
9920 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9922 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9923 autogenerated by the maintainer.
9924 * examples/calc++/.cvsignore: Add *.yy.
9926 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9927 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9928 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9930 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9932 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9933 from maintainer-distcheck about casting the argument of 'free'.
9935 * NEWS: Mention recent yytname changes.
9936 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9938 * bootstrap: For translations that have not yet been upgraded to
9939 the new runtime-po domain, prime the pump by extracting the
9940 relevant strings from the obsolete translations. This code can be
9941 removed once the bison-runtime domain has been translated by each
9944 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9945 now that token names are already quoted.
9947 Fix problem reported by Anthony Heading.
9948 * data/glr.c (YYTOKEN_TABLE): New macro.
9949 (yytname): Define if YYTOKEN_TABLE.
9950 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
9951 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
9952 (YYERROR_VERBOSE): Define the same way the other skeletons do.
9953 * src/output.c (prepare_symbols): Output token_table_flag.
9955 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9957 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9958 again if the first call fails.
9960 * data/glr.c (yytnamerr): New function.
9961 (yyreportSyntaxError): Use it to dequote most string literals.
9962 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9963 with other skeletons. All uses changed.
9964 (yytnameerr_): New function.
9965 (yyreport_syntax_error): Use it to dequote most string literals.
9966 * data/yacc.c (yytnamerr): New function.
9967 (yyerrlab): Use it to decode most string literals.
9968 * doc/bison.texinfo (Decl Summary, Calling Convention):
9969 Clarify quoting convention of yytname.
9970 * src/output.c (prepare_symbols): Quote all names. This undoes
9971 the 2005-04-17 change, which is now accomplished (mostly) via
9972 changes in the parsers as described above.
9973 * tests/regression.at (Token definitions, Web2c Actions):
9974 Undo most 2005-04-17 change here, too.
9976 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9978 Fix more problems reported by twlevo@xs4all.nl.
9979 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9980 remove trailing spaces. This loses the exit status of ./types,
9981 and isn't needed since ./types shouldn't be emitting trailing
9983 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9984 as the stack isn't valid in that case.
9986 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):

9988 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9989 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9991 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
9992 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9993 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9996 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9997 overly-picky compilers that reject 'char *foo = "bar";'.
9999 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
10000 to FILE * parameter, not to stderr. This fixes a typo introduced
10001 in the 2005-07-12 change.
10003 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
10004 warnings from GCC 4.
10006 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
10007 (yyglrShiftDefer, yysplitStack):
10008 Remove unused parameters b4_pure_formals. All uses changed.
10009 (yyglrShift): Remove unused parameters b4_user_formals.
10011 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
10013 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
10015 Destructor cleanups and regularization among the three skeletons.
10016 * NEWS: Document the behavior changes.
10017 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
10018 stack before failing, as the cleanup code will do it for us now.
10019 * data/lalr1.cc (yyerrlab): Likewise.
10020 * data/glr.c (yyparse): Pop everything off the stack before
10021 freeing it, so that destructors get called properly.
10022 * data/lalr1.cc (yyreturn): Likewise.
10023 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
10024 This is more consistent.
10025 * doc/bison.texinfo (Destructor Decl): Mention more reasons
10026 why destructors might be called. 1.875 -> 2.1.
10027 (Destructor Decl, Decl Summary, Table of Symbols):
10028 Some English-language cleanups for %destructor.
10029 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10030 Add output line for destructor of start symbol.
10031 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
10032 because of that same extra output line.
10034 * NEWS: Document minor wording changes in diagnostics of
10035 Bison-generated parsers.
10036 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
10037 Remove unused formals. All uses changed.
10038 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
10039 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
10040 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
10041 Rename yyoverflowab to yyexhaustedlab.
10042 When memory exhaustion occurs during syntax-error reporting,
10043 report it separately rather than in a single diagnostic; this
10045 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
10046 (Memory Exhausted): Renamed from Parser Stack Overflow.
10047 Revamp wording slightly to prefer "memory exhaustion".
10048 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
10050 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
10052 Add i18n support to the GLR skeleton. Partially fix the C++
10053 skeleton; a C++ expert needs to finish this. Remove debugging
10054 msgids; there's little point to having them translated, since they
10055 can be understood only by someone who can read the
10056 (English-language) source code.
10058 Generate runtime-po/bison-runtime.pot automatically, so that we
10059 don't have to worry about garbage getting in that file. We'll
10060 make sure after the next official release that old msgids don't
10062 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
10064 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10065 Now auto-generated.
10066 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10067 Fix typos in explanations of the runtime file.
10068 * bootstrap: Change gettext keyword from YYI18N to YY_.
10069 Use standard Makefile.in.in in runtime-po, since we'll arrange
10070 for backward-compatible bison-runtime.po files in a different way.
10071 * data/glr.c (YY_): New macro, from yacc.c.
10072 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10073 Translate messages intended for users.
10074 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10075 the wording in the other skeletons. We don't know that the memory
10077 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10078 Use same method that yacc.c uses.
10079 Don't translate debugging messages.
10080 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10081 it doesn't work (yet), and requires C++ expertise to fix.
10082 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10083 Move defn to a more logical place, to be consistent with other
10085 Don't translate debugging messages.
10086 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10087 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10088 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10089 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
10091 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
10092 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
10094 * tests/glr-regression.at (Badly Collapsed GLR States):
10096 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
10097 yylex should return 0 at EOF rather than aborting.
10099 Improve tests for stack overflow in GLR parser.
10100 Problem reported by twlevo@xs4all.nl.
10101 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
10103 (yyStackOverflow): Just longjmp, but with value 2 so that caller
10104 can handle the problem.
10105 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
10106 (yyparse): New local variable yyresult to record the result.
10107 Use result of setjmp to set it, rather than storing itinto
10109 (yyDone): Remove label.
10110 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
10111 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
10112 if YYABORT is used).
10113 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
10114 yyparse status; put status > 1 into diagnostic.
10115 Check that status==2 works.
10116 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
10117 Use exit status 3 for failure to open (which shouldn't happen).
10119 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
10121 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
10122 1 on syntax error; just let yyparse do its thing.
10123 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
10124 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
10125 (Exploding the Stack Size with Alloca):
10126 (Exploding the Stack Size with Malloc):
10127 Expect exit status 2, not 1, since the parser is supposed to blow
10128 its stack. Problem reported by twlevo@xs4all.nl.
10130 * data/glr.c (yyparse): Don't assume that the initial calls
10131 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
10132 Print a stack-overflow message and fail instead.
10133 Initialize the line-number information before creating the stack,
10134 so that the stack-overflow message can report line zero safely.
10136 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
10138 Fix problems reported by twlevo@xs4all.nl.
10139 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
10140 (yyuserMerge): Provide a default case if b4_mergers is empty.
10141 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
10142 * tests/glr-regression.at
10143 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
10144 Add casts to pacify C++ compilers.
10145 * tests/glr-regression.at (Improper merging of GLR delayed action
10146 sets): Declare yylex before using it.
10147 * tests/Makefile.am (maintainer-check-g++): Fix a stray
10148 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
10149 test for valgrind; valgrind is independent of g++.
10150 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
10151 for compatibility with POSIX 1003.1-2001 (if running coreutils).
10152 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
10153 Use a destructor, so that we can expand the stack. Change
10154 YYSTYPE to char * so that we can free it. Cast result of malloc.
10156 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10158 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
10159 a valgrind failure. Problem reported by twlevo@xs4all.nl.
10161 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
10163 * PACKAGING: New file, suggested by Bruno Haible and taken from
10164 similar wording in gettext's PACKAGING file.
10165 * NEWS: Mention PACKAGING.
10166 * Makefile.am (EXTRA_DIST): Add PACKAGING.
10168 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
10170 * NEWS: Document recent i18n improvements.
10171 * bootstrap: Get runtime translations into runtime-po.
10172 Create runtime-po files automatically, if possible.
10173 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
10174 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
10175 does not infringe on the user's name space.
10176 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
10177 * doc/bison.texinfo (Internationalization): Revamp the English
10178 and Texinfo syntax a bit, to try to make it clearer.
10179 (Bison Options, Option Cross Key): Mention --print-localedir.
10180 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
10181 YYENABLE_NLS. Quote a bit more.
10182 * runtime-po/.cvsignore: New file.
10183 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
10184 * runtime-po/Rules-quot: Remove; now created by bootstrap.
10185 * runtime-po/quot.sed: Likewise.
10186 * runtime-po/boldquot.sed: Likewise.
10187 * runtime-po/en@quot.header: Likewise.
10188 * runtime-po/en@boldquot.header: Likewise.
10189 * runtime-po/insert-header.sin: Likewise.
10190 * runtime-po/remove-potcdate.sin: Likewise.
10191 * runtime-po/Makevars: Likewise.
10192 * runtime-po/LINGUAS: Likewise.
10193 * runtime-po/de.po: Likewise; we will rely on the translation project
10194 to maintain this, so "bootstrap" should get it.
10195 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
10197 * src/main.c (main): Bind the bison-runtime domain, too.
10199 2005-07-12 Bruno Haible <bruno@clisp.org>
10201 * data/yacc.c: Include <libintl.h> when NLS is enabled.
10202 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
10203 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
10204 * runtime-po: New directory.
10205 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
10206 $(DOMAIN).pot-update rule, so that old messages are never dropped.
10207 * runtime-po/Rules-quot: New file, copied from po/.
10208 * runtime-po/quot.sed: Likewise.
10209 * runtime-po/boldquot.sed: Likewise.
10210 * runtime-po/en@quot.header: Likewise.
10211 * runtime-po/en@boldquot.header: Likewise.
10212 * runtime-po/insert-header.sin: Likewise.
10213 * runtime-po/remove-potcdate.sin: Likewise.
10214 * runtime-po/Makevars: New file.
10215 * runtime-po/POTFILES.in: New file.
10216 * runtime-po/LINGUAS: New file.
10217 * runtime-po/bison-runtime.pot: New file.
10218 * runtime-po/de.po: New file.
10219 * m4/bison.m4: New file.
10220 * Makefile.am (SUBDIRS): Add runtime-po.
10221 (aclocaldir, aclocal_DATA): New variables.
10222 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
10224 * src/getargs.c (usage): Document --print-localedir option.
10225 (PRINT_LOCALEDIR_OPTION): New enum item.
10226 (long_options): Add --print-localedir option.
10227 (getargs): Handle --print-localedir option.
10228 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
10229 (Internationalization): New section.
10231 2005-07-12 Akim Demaille <akim@epita.fr>
10233 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
10234 for consistency with the rest of the code.
10235 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
10238 2005-07-12 Akim Demaille <akim@epita.fr>
10240 * src/parse-gram.y: Use %printer instead of YYPRINT.
10242 2005-07-12 Akim Demaille <akim@epita.fr>
10244 * src/symtab.h, src/symtab.c (symbol_print): New.
10245 * src/symlist.h, src/symlist.c (symbol_list_print): New.
10246 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
10248 2005-07-12 Akim Demaille <akim@epita.fr>
10250 * data/glr.c (b4_syncline): Fix (swap) the definitions of
10251 b4_at_dollar and b4_dollar_dollar.
10253 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
10255 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
10256 and Pennello's paper.
10258 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
10260 * data/yacc.c (yyparse): Undo previous patch. Instead,
10261 set yylsp[0] and yyvsp[0] only if the initial action
10262 sets yylloc and yylval, respectively.
10264 * data/yacc.c (yyparse): In the initial action, set
10265 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
10266 This avoids the use of undefined variables if the initial
10267 action does not set yylloc and/or yylval.
10269 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10271 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
10272 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
10273 Remove from CVS. These files are automatically generated.
10274 * examples/extexi: Clarify that this file is now part of Bison,
10275 not GNU M4, and that it works with any POSIX-compatible Awk.
10276 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
10277 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
10278 so that we also get calc++-parser.yy. Geneate it.
10279 Use $(AWK), not gawk, since any conforming Awk will do.
10280 Put comment before action, since older 'make' can't handle comment
10282 $(BUILT_SOURCES): List all built sources, not just some of them.
10283 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
10284 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
10285 $($(calc_sources_generated)): Remove unnecessary test for existence
10286 of target. (This had a shell syntax error anyway; a stray "x".)
10287 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
10289 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
10291 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
10292 implied by the other modules.
10294 2005-07-06 Akim Demaille <akim@epita.fr>
10296 Bind examples/calc++ to the package.
10297 * examples/calc++/Makefile: Remove, replaced by...

10299 * examples/calc++/test: Remove input.
10300 * examples/calc++/compile: Remove.
10301 * examples/Makefile.am: New.

10305 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
10307 * data/glr.c (yyFail): Drastically simplify; since the format argument
10308 never had any % directives, we can simply pass it to yyerror.
10309 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
10310 be modified later, as that is the usual style in glr.c.
10311 Problems reported by Paul Hilfinger.
10313 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
10314 and size overflow errors.
10315 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
10316 in case the user prolog sets feature-test macros like _GNU_SOURCE.
10317 (YYSIZEMAX): New macro.
10318 (yystpcpy): New function, taken from yacc.c.
10319 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
10320 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
10321 so that we don't have to maintain their signatures.
10322 (yyFail): Check for buffer overflow, by using vsnprintf rather
10323 than vsprintf. Allocate a bigger buffer if possible.
10324 Report an error if buffer allocation fails.
10325 (yyStackOverflow): New function.
10326 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
10327 the initialization was successful. It might fail if storage was
10329 (yyexpandGLRStack): Add more checks for storage allocation failure.
10330 Use yyStackOverflow to report failures.
10331 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
10332 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
10333 Don't assume stack number fits in int.
10334 (yysplitStack): Check for storage allocation failure.
10335 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
10336 can print diagnostics on storage allocation failure. All callers
10338 (yyresolveValue): Use yybool for boolean.
10339 (yyreportSyntaxError): Check for size-calculation overflow.
10340 This code is taken from yacc.c.
10341 (yyparse): Check for storage allocation errors when allocating
10344 2005-07-05 Akim Demaille <akim@epita.fr>
10346 Extract calc++ from the documentation.
10347 * doc/bison.texinfo (Calc++): Add the extraction marks.
10348 * examples/extexi: New, from the aborted GNU Programming 2E.
10349 Separate the different paragraph of a file with empty lines.
10350 * examples/Makefile: Use it to extract the whole calc++ example.
10352 2005-06-24 Akim Demaille <akim@epita.fr>
10354 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
10357 2005-06-22 Akim Demaille <akim@epita.fr>
10359 * doc/bison.texinfo (C++ Language Interface): First stab.
10360 (C++ Parsers): Remove.
10362 2005-06-22 Akim Demaille <akim@epita.fr>
10364 * data/lalr1.cc (yylex_): Honor %lex-param.
10366 2005-06-22 Akim Demaille <akim@epita.fr>
10368 Start a set of simple examples.
10369 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
10370 * examples/calc++/calc++-driver.hh,
10371 * examples/calc++/calc++-parser.yy,
10372 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
10373 * examples/calc++/compile, examples/calc++/test: New.
10375 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
10377 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
10378 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
10379 which stems from the 2005-05-27 patch.
10381 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
10383 * data/glr.c: Modify treatment of unused parameters to permit use
10384 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
10386 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
10388 Fix infringement on user name space reported by Janos Zoltan Szabo.
10389 * data/yacc.c (yyparse): strlen -> yystrlen.
10391 2005-05-30 Akim Demaille <akim@epita.fr>
10393 * data/lalr1.cc (_): New.
10394 Translate the various messages.
10396 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
10398 Fix infringement on user name space reported by Bruno Haible.
10399 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
10400 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
10401 the user's name space.
10402 (alloca): Include <stdlib.h> to get it, if it's not built in.
10403 (YYMALLOC, YYFREE): Define only if needed.
10404 (malloc, free): Declare, but only if needed, as this infringes on
10405 the user name space.
10407 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10409 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
10410 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
10412 * lib/ebitset.c (min, max): Undef before defining.
10413 * lib/vbitset.c (min, max): Likewise.
10414 * lib/subpipe.c (create_subpipe): Save local variables in case
10415 vfork clobbers them.
10417 2005-05-24 Bruno Haible <bruno@clisp.org>
10419 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
10420 error message syntax used by gcc-4.0.
10422 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
10424 * README: Mention m4 1.4.3. Remove obsolete advice about
10425 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
10427 * bootstrap: Remove workaround for problem I encountered with
10428 gettext 0.14.1; it seems to be fixed now.
10430 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
10432 * NEWS: Version 2.0a.
10434 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
10435 the previous change.
10437 Various maintainer cleanups.
10438 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
10439 conftest*, for benefit of CVS commands run at the same time as
10440 "configure". Add build-aux, since "bootstrap" now creates it and
10442 * Makefile.cfg (move_if_change): Remove.
10443 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
10444 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
10445 (po_repo, do-po-update, po-update, wget_files, get-targets):
10446 (config.guess-url_prefix, config.sub-url_prefix):
10447 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
10448 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
10449 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
10451 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
10452 this is now the recommended name.
10453 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
10454 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
10455 ylwrap. These files now go into build-aux.
10456 * config/move-if-change: Remove.
10457 * config/prev-version.txt: Bump from 1.75 to 2.0.
10459 * bootstrap: Add stdio-safer, unistd-safer modules.
10460 Remove m4/glibc2.m4 (introduced by latest gnulib, but
10462 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
10463 fopen-safer.c, stdio-safer.h, unistd-safer.h.
10464 * lib/subpipe.c: Include "unistd-safer.h".
10465 (create_subpipe): Make sure all the newly-created
10466 file descriptors are > 2, so that diagnostics don't
10467 get sent down them (which might cause Bison to hang, in theory).
10468 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
10469 * src/files.c (xfopen): Use fopen_safer, not fopen.
10471 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
10472 yesterday's yacc.c fix.
10474 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
10476 * data/glr.c, data/lalr1.cc: Update copyright date.
10478 Fix a destructor bug reported by Wolfgang Spraul in
10479 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
10480 * data/yacc.c (yyabortlab): Don't call destructor, and
10481 don't set yychar to EMPTY.
10482 (yyoverflowlab): Don't call destructor.
10483 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
10484 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
10485 since we no longer output the message "discarding lookahead token
10488 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10490 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
10491 fix a small glitch in debugging output.
10492 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
10493 after YY_SYMBOL_PRINT where needed.
10495 (struct yyGLRState): Add some comments.
10496 (struct yySemanticOption): Add some comments.
10497 (union yyGLRStackItem): Add comment.
10499 (yymergeOptionSets): Correct this to properly perform the union,
10500 avoiding infinite reported by Michael Rosien.
10503 * tests/glr-regression.at: Add test for GLR merging error reported

10544 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
10546 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
10547 Problem reported by Ralf Menzel.
10549 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10551 * tests/actions.at: Test that stack overflow invokes destructors.
10552 From Marcus Holland-Moritz.
10553 * data/yacc.c (yyerrlab): Move the code that destroys the stack
10555 (yyreturn): to here. That way, destructors are called properly
10556 even if the stack overflows, or the user calls YYACCEPT or
10557 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
10558 (yyoverflowlab): Destroy the lookahead.
10560 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
10562 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
10564 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
10566 * NEWS: Bison-generated C parsers no longer quote literal strings
10567 associated with tokens.
10568 * src/output.c (prepare_symbols): Don't escape strings,
10569 since users don't want to see C escapes.
10570 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
10572 * tests/input.at (Torturing the Scanner): Likewise.
10573 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
10575 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
10577 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
10578 the data size is known to be too small and we can't increase it.
10579 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
10581 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
10583 * src/parse-gram.y: Include quotearg.h.
10584 (string_as_id): Quote $1 before using it as a key, since the
10585 lexer no longer quotes it for us.
10586 (string_content): Don't strip quotes, since lexer no longer
10588 * src/scan-gram.l: Include quotearg.h.
10589 ("\""): Omit quote.
10590 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
10591 a key, since the rest of the lexer doesn't quote it.
10592 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
10593 * tests/regression.at (Token definitions): Check for backslashes
10596 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
10597 (YYSIZE_T): Define to unsigned long int when using an older compiler.
10598 (yyparse): Revamp code to generate long syntax error message, to
10599 make it easier to translate, and to avoid problems with arithmetic
10600 overflow. Change "virtual memory" to "memory" in diagnostic, since
10601 we don't know whether the memory is virtual.
10603 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10605 * NEWS: Bison-generated C parsers now use the _ macro to
10607 * data/yacc.c (_) [!defined _]: New macro.
10608 All English strings wrapped inside this macro.
10609 * doc/bison.texinfo (Bison Parser): Document _.
10610 * po/POTFILES.in: Include src/parse-gram.c, since it now
10611 includes translateable strings that parse-gram.y doesn't.
10613 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
10615 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
10616 reverting the 2004-10-11 change to this function.
10617 (symbol_check_alias_consistency): Don't call symbol_type_set
10618 if the type name is already correct.
10619 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
10621 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
10623 * tests/regression.at (Token definitions): Don't use a token named
10624 c, as that generates a "#define c ..." that runs afoul of buggy
10625 stdlib.h that uses the identifier c as a member of struct
10626 drand48_data. Problem reported by Horst Wente.
10628 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
10630 * bootstrap: Change translation URL from
10631 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
10632 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
10633 redirection glitches. Problem reported by twlevo@xs4all.nl.
10635 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
10637 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
10638 after operands; POSIX says this isn't portable for the c99 command.
10640 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
10642 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
10643 immediately if a data overrun has occurred; this may help us track
10644 down what may be a spurious failure on MacOS.
10646 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
10648 Respond to problems reported by twlevo@xs4all.nl.
10650 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
10652 * src/vcg.h: Comment fix.
10653 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
10654 (G_CMAX): Change to -1 instead of INT_MAX.
10656 * data/yacc.c (yyparse): Omit spaces before #line.
10658 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
10660 * src/tables.c (state_number_to_vector_number): Put it inside an
10661 "#if 0", since it's not currently used. Problem reported by
10664 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
10666 * src/output.c (escaped_output): Renamed from
10667 escaped_file_name_output, since we now use it for symbol tags as
10668 well. All uses changed.
10669 (symbol_destructors_output, symbol_printers_output):
10670 Escape symbol tags too.
10671 Problem reported by Matyas Forstner in
10672 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
10674 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
10676 * src/output.c (user_actions_output, token_definitions_output,
10677 symbol_destructors_output, symbol_printers_output): Likewise.
10678 * src/reader.c (prologue_augment): Likewise.
10679 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
10681 * src/vcg.c (output_edge): Don't quote linestyle arg.
10682 Problem reported by twlevo@xs4all.nl.
10684 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
10686 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
10687 example, reported by Derek M Jones. Also, make the example even
10688 more outrageous, to better illustrate how bad the problem is.
10690 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
10692 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
10693 putsym. Typo reported by Sebastian Piping.
10695 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10697 * doc/bison.texinfo (Language and Grammar): some -> same
10698 (Epilogue): int he -> in the
10699 Typos reported by Sebastian Piping via Justin Pence.
10701 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10703 * tests/glr-regression.at (Improper handling of embedded actions
10704 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
10705 embedded actions and $-N in GLR parsers", work around an Autoconf bug
10706 with dollar signs in test names.
10707 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
10708 for a similar reason.
10710 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
10712 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
10713 wants to redefine G_VIEW.
10715 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
10717 * src/vcg.c (get_view_str): Remove case for normal_view.
10718 Problem reported by twlevo@xs4all.nl.
10720 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
10722 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
10723 Problem reported by twlevo@xs4all.nl.
10725 * doc/bison.texinfo: Change @dircategory from "GNU programming
10726 tools" to "Software development". Requested by Richard Stallman
10729 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
10731 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
10732 Problem reported by twlevo@xs4all.nl.
10734 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
10736 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
10737 keyword; it's not needed with modern compilers, and it doesn't
10738 affect correctness with older compilers. Suggested by
10741 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
10743 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
10744 gcc -Wswitch-default.
10745 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10746 * data/yacc.c (yyparse): Likewise.
10748 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
10750 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
10751 already. Let config.h define any nonstandard values.
10753 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
10755 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
10756 for the benefit of slower hosts. Problem reported by
10757 Nelson H. F. Beebe.
10759 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
10761 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
10762 being defined and not used.
10763 * data/lalr1.cc (yyparse): Likewise.
10764 Use "if (false)" rather than "if (0)".
10766 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
10768 * TODO: Mention that we should allow NUL bytes in tokens.
10770 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
10772 * src/scan-skel.l (<<EOF>>): Don't close standard output.
10773 Problem reported by Hans Aberg.
10775 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
10777 * src/getargs.c (version): Happy new year; update overall
10778 program copyright date from 2004 to 2005.
10780 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
10781 Problem reported by Hans Aberg.
10782 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
10783 (Output file names.): Add a test for the case when standard output
10786 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
10788 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
10789 to fix an oversight in the Bison 2.0 manual.
10791 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
10793 * NEWS: Version 2.0. Reformat the existing news items since
10794 1.875, so that related items are grouped together.
10795 * configure.ac (AC_INIT): Bump version to 2.0.
10796 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
10798 * tests/torture.at (Exploding the Stack Size with Alloca): Set
10799 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
10800 otherwise, we're not testing alloca. Unfortunately there's no
10801 simple way to consult HAVE_ALLOCA here.
10803 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
10806 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
10807 hand. This avoids a warning about comparing int to size_t when
10808 GCC warnings are enabled.
10810 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
10812 * NEWS: Bison-generated parsers no longer default to using the
10813 alloca function (when available) to extend the parser stack, due
10814 to widespread problems in unchecked stack-overflow detection.
10815 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
10816 responsibility to set it to a positive value. This lets the user
10817 specify a value that is not a preprocessor constant.
10818 * data/yacc.c (YYMAXDEPTH): Likewise.
10819 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
10820 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
10821 to be a compile-time constant. However, explain the constraints on it.
10822 Also, explain the constraints on YYINITDEPTH.
10823 (Table of Symbols): Explain that alloca is no longer the default.
10824 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
10827 * doc/bison.texinfo (Location Default Action): Mention that n must
10828 be zero when k is zero. Suggested by Frank Heckenbach.
10830 2004-12-22 Akim Demaille <akim@epita.fr>
10832 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
10833 (parser::state_type, parser::semantic_type, parser::location_type):
10834 Private, not public.
10835 (parser::parse): Return ints, not bool.
10836 Returning a bool introduces a problem: 0 corresponds to false, and
10837 it seems weird to return false on success. Returning true changes
10838 the conventions for yyparse.
10839 Alternatively we could return void and send an exception.
10840 There is no clear consensus (yet?).
10841 (state_stack, semantic_stack, location_stack): Rename as...
10842 (state_stack_type, semantic_stack_type, location_stack_type): these.
10843 Private, not public.
10844 * tests/c++.at: New.
10845 * tests/testsuite.at, tests/Makefile.am: Adjust.
10847 2004-12-21 Akim Demaille <akim@epita.fr>
10849 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
10851 2004-12-21 Akim Demaille <akim@epita.fr>
10853 Don't impose std::string for filenames.
10855 * data/lalr1.cc (b4_filename_type): New.
10856 (position::filename): Use it.
10857 (parser.hh): Move the inclusion of stack.hh and location.hh below
10858 the user code, so that needed headers for the filename type can be
10860 Forward declare them before the user code.
10861 * tests/Makefile.am (check-local, installcheck-local): Pass
10862 TESTSUITEFLAGS to the TESTSUITE.
10864 2004-12-20 Akim Demaille <akim@epita.fr>
10866 Use more STL like names: my_class instead of MyClass.
10868 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
10869 (SemanticStack, SemanticType, StateStack, StateType)
10870 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10871 (Parser::value): Rename as...

10873 (semantic_type, state_stack, state_type, token_number_type, stack)
10874 (slice, traits, parser::yylloc, parser::yylval): these.
10876 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10878 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10880 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10881 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10883 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10885 Remove uses of 'short int' and 'unsigned short int'. This raises
10886 some arbitrary limits. It uses more memory but nowadays that's
10887 not much of an issue.
10889 This change does not affect the generated parsers; that's a different
10890 task, as some users will want to conserve memory there.
10892 Ideally we should use size_t to represent all object counts, and
10893 something like ptrdiff_t to represent signed differences of object
10894 counts; but that will require more code-cleanup than I have the
10895 time to do right now.
10897 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10898 Use size_t, not int or short int, to count objects.
10899 * src/closure.c (nritemset, closure): Likewise.

10918 2004-12-17 Akim Demaille <akim@epita.fr>
10920 * data/lalr1.cc: Extensive Doxygenation.
10921 (error_): Rename as...
10922 (error): this, since it is visible to the user.
10924 (Parser::message): Now an automatic variable from...
10925 (Parser::yyreport_syntax_error_): here.
10926 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10928 * tests/input.at: Escape $.
10930 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
10932 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10933 Parenthesize rhs to avoid obscure problems with mistakes like
10934 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10935 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10936 b4_rhs_location): Likewise.

10938 b4_rhs_location): Likewise.
10940 2004-12-16 Akim Demaille <akim@epita.fr>
10942 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10943 yacc.c: be sure to stay within yycheck_.
10944 * tests/actions.at: Re-enable C++ tests.
10946 2004-12-16 Akim Demaille <akim@epita.fr>
10948 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
10951 2004-12-16 Akim Demaille <akim@epita.fr>
10953 Use #define to handle the %name-prefix.
10955 * data/glr.c, data/yacc.c: Comment changes.
10956 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10957 so that one can refer to yylex in the parser file, and have it
10958 renamed, as is the case with other skeletons.
10960 2004-12-16 Akim Demaille <akim@epita.fr>
10962 Move lalr1.cc internals into yy*.

10982 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10984 Fix some problems reported by twlevo at xs4all.
10985 * src/symtab.c (symbol_new): Report an error if the input grammar
10986 contains too many symbols. This is better than calling abort() later.
10987 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10988 (struct node, struct graph):
10989 Rename member expand to stretch. All uses changed.

10991 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
10992 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
10994 (N_STRETCH): Rename from N_EXPAND. All uses changed.
10996 2004-12-15 Akim Demaille <akim@epita.fr>
10998 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
10999 Add more Doxygen comments.
11000 (symprint_, stack_print_, reduce_print_, destruct_, pop)
11001 (report_syntax_error_, translate_): Rename as...
11002 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
11003 (yypop_, yyreport_syntax_error_, yytranslate_): this.
11005 2004-12-15 Akim Demaille <akim@epita.fr>
11007 * data/lalr1.cc (lex_): Rename as...
11009 Move the trace here.
11010 Take the %name-prefix into account.
11011 Reported by Alexandre Duret-Lutz.
11013 2004-12-15 Akim Demaille <akim@epita.fr>
11015 Simplify the C++ parser constructor.
11017 * data/lalr1.cc (debug_): Rename as...
11018 (yydebug_): so that the parser's internals are always in the yy*
11021 (b4_parse_param_decl): Remove the leading comma as it is now only
11022 called as unique argument list.
11023 (Parser::Parser): Remove the constructor accepting a location and
11024 an initial debugging level.
11025 Remove from the other ctor the argument for the debugging level.
11026 (debug_level_type, debug_level, set_debug_level): New.
11028 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
11031 2004-12-15 Akim Demaille <akim@epita.fr>
11033 Remove b4_root related material: failure experiment
11034 (which goal was to allow to derive from a class).
11036 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
11037 definitions and uses.
11039 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
11041 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
11042 not 2, since it's not portable to subtract 1 from the start of an
11043 array. The new item 0 is never set or used. All uses changed.
11045 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
11046 the default definition of YYLLOC_DEFAULT. Problem reported
11047 by Frank Heckenbach.
11049 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
11051 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
11052 the normal case and one for the error case. Just use the
11053 first one uniformly. Problem reported by Frank Heckenbach.
11054 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
11055 use exactly the same macro in both places.
11056 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
11057 so that the normal-case YYRHSLOC works for the error case too.
11059 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
11060 (YYLLOC_DEFAULT): Use the same macro as glr.c.
11061 * doc/bison.texinfo (Location Default Action): Don't claim that
11062 we have an array of locations. Use the same macro for both glr
11063 and lalr parsers. Mention YYRHSLOC. Mention what happens when
11066 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11068 * HACKING: Update email addresses to send announcements to.
11070 * configure.ac (AC_INIT): Bump version to 1.875f.
11072 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11074 * NEWS: Version 1.875e.
11075 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
11077 * src/scan-skel.l: Include "complain.h", for "fatal".
11079 * src/relation.h (relation_print, relation_digraph):
11080 Relation sizes are of type relation_node, not size_t (this is
11081 merely a doc fix, since the two types are equivalent).
11082 (relation_transpose): Relation sizes are of type relation_node,
11084 * src/relation.c: Likewise.
11085 (top, infinity): Now of type relation_node, not int.
11086 (traverse, relation_transpose): Use relation_node, not int.
11088 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
11089 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
11090 (yyparse): Remove unused local introduced in 2004-10-25 patch.
11092 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
11093 specifying whether the test should be skipped. Use it tp
11094 specify that the [%defines %skeleton "lalr1.cc"] tests currently
11095 fail on some hosts, and should be skipped.
11097 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
11099 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
11100 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
11101 unless otherwise specified below.
11103 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
11104 to allocate kernel_base, kernel_items, kernel_size, since
11105 they needn't be initialized to 0.
11106 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
11107 * src/closure.c (new_closure): Likewise, for itemset.
11108 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

11111 (build_relations): Likewise for edge, states1, includes.
11112 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
11113 * src/reader.c (packgram): Likewise, for ritem, rules.
11114 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
11115 * src/relation.c (relation_digraph): Likewise for VERTICES.
11116 (relation_transpose): Likewise for new_R, end_R.
11117 * src/symtab.c (symbols_token_translations_init): Likewise for
11118 token_translations.
11119 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
11120 (token_actions): Likewise for yydefact, actrow, conflrow,
11122 (save_column): Likewise for froms[symno], tos[symno].
11123 (goto_actions): Likewise for state_count.
11124 (pack_table): Likewise for base, pos, check.
11125 (tables_generate): Likewise for width.
11127 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
11128 for initial core. Just have a separate core, so we needn't worry
11129 about whether kernel_size and kernel_base are initialized.
11131 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
11132 kernel_size, kernel_items): Remove unnecessary initialization.
11133 * src/conflicts.c (conflicts): Likewise.
11134 * src/derives.c (derives): Likewise.
11135 * src/muscle_tablc (muscle_insert): Likewise.
11136 * src/relation.c (relation_digraph): Likewise.
11137 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
11138 conflrow, conflict_table, conflict_list, table, check):
11141 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
11142 This is because all callers pass unsigned int.
11143 * src/closure.h (new_closure): Likewise.
11145 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
11146 (build_relations): Initialize includes[i] in all cases.
11147 * src/reader.c (packgram): Always initialize rules[ruleno].prec
11148 and rules[ruleno].precsym. Initialize members in order.
11149 * src/relation.c (relation_transpose): Always initialize new_R[i]
11151 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
11153 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
11154 conflict_list[0] was always 0, but now it isn't initialized.
11156 * src/table.c (table_grow): When conflict_table grew, the grown
11157 area wasn't cleared. Fix this.
11159 * lib/.cvsignore: Add strdup.c, strdup.h.
11160 * m4/.cvsignore: Add strdup.m4.
11162 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
11164 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
11165 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
11166 GOTO_NUMBER_MAXIMUM, since we occasionally compute
11167 ngotos + 1 without checking for overflow.
11168 (build_relations): Use END_NODE, not -1, to denote end of edges.
11169 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
11170 build_relations): Use goto_number, not int, for goto numbers.
11171 * src/tables.c (save_column, default_goto): Likewise.
11173 2004-11-23 Akim Demaille <akim@epita.fr>
11175 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
11176 of #defining from yystype.
11177 Don't typedef yystype, C++ does not need it.
11178 This lets it possible to forward declare it as union.
11180 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
11182 * bootstrap (gnulib_modules): Add extensions.
11183 Problem reported by Jim Meyering.
11185 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
11187 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
11188 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
11189 src/system.h, src/tables.c: XFREE -> free, to accommodate
11190 recent change to gnulib xalloc.h.
11191 Problem reported by Jim Meyering.
11193 2004-11-17 Akim Demaille <akim@epita.fr>
11195 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
11197 2004-11-17 Akim Demaille <akim@epita.fr>,
11198 Alexandre Duret-Lutz <adl@gnu.org>
11200 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
11202 (YYCDEBUG): Adjust.
11203 Use it instead of cdebug_.
11204 (Parser::debug_stream, Parser::set_debug_stream): New.
11205 (Parser::symprint_): Define cdebug_ for temporary backward
11207 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
11210 2004-11-17 Akim Demaille <akim@epita.fr>
11212 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
11213 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
11214 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
11215 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11217 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
11219 * data/glr.c (yyloc_default): Remove; not used.
11220 Problem reported by Frank Heckenbach.
11222 2004-10-25 Akim Demaille <akim@epita.fr>
11224 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
11225 Introduce another definition to address simple location arrays.
11226 (yyGLRStack): New member: yyerror_range.
11227 (yyrecoverSyntaxError, yyparse): Update it.
11228 (yyrecoverSyntaxError): Use it when shifting the error token to
11229 have an accurate range, equivalent to the one computed by both
11230 yacc.c and lalr1.cc.
11231 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
11232 that column numbers start at column 0, as per GNU Coding
11233 Standards, the others tests, and the doc.
11234 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
11235 Adjust to the above change (first column is 0).
11236 And adjust the location of the "<error>", now covering the whole
11239 2004-10-22 Akim Demaille <akim@epita.fr>
11240 and Paul Eggert <eggert@cs.ucla.edu>
11242 Remove some arbitrary limits on goto numbers and relations.
11243 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
11244 initial values, since they're never used.
11245 (set_goto_map): ngotos is now unsigned, so test for overflow
11246 by seeing whether it wraps around to zero.
11247 * src/lalr.h (goto_number): Now size_t, not short int.
11248 (GOTO_NUMBER_MAXIMUM): Remove.
11249 * src/relation.c (relation_print, traverse, relation_transpose):
11250 Check for END_NODE rather than looking at sign.
11251 * src/relation.h (END_NODE): New macro.
11252 (relation_node): Now size_t, not short int.
11254 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
11256 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
11257 keyword, not an identifier. Problem reported by Baron Schwartz in
11258 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
11260 2004-10-11 Akim Demaille <akim@epita.fr>
11262 * src/symtab.c (symbol_check_alias_consistency): Also check
11263 type names, destructors, and printers.
11264 Reported by Alexandre Duret-Lutz.
11265 Recode the handling of associativity and precedence in terms
11266 of symbol_precedence_set.
11267 Accept no redeclaration at all, not even equal to the previous
11269 (redeclaration): New.
11270 Use it to factor redeclaration complaints.
11271 (symbol_make_alias): Don't set the type of the alias, let
11272 symbol_check_alias_consistency do it as for other features.
11273 * src/symtab.h (symbol): Add new member prec_location, and
11275 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
11276 * tests/input.at (Incompatible Aliases): New.
11278 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
11280 .cvsignore fixes to accommodate gnulib changes,
11281 and the practice of naming build directories "_build".
11282 * .cvsignore: Add "_*". Sort.
11283 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
11284 * m4/.cvsignore: Add "*_gl.m4".
11286 2004-10-06 Akim Demaille <akim@epita.fr>
11288 * src/parse-gram.y (add_param): Fix the truncation of trailing
11291 2004-10-05 Akim Demaille <akim@epita.fr>
11293 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11294 whether the reducion was empty or not. This leaves room to
11295 improve the use of YYLLOC_DEFAULT in such a case.
11296 lalr1.cc is still experimental, so changing this is acceptable.
11297 And finally, there are probably not many users who changed the
11298 handling of locations in GLR, so changing is admissible too.
11300 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
11301 empty reduction, set @$ to an empty location ending the previously
11303 Adjust uses to make sure the code is triggered on empty
11305 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
11306 expected output: empty reductions have empty locations.
11308 2004-09-29 Akim Demaille <akim@epita.fr>
11310 * data/lalr1.cc: Move towards a more standard C++ coding style
11311 for templates: Class < T > -> Class<T>.
11313 2004-09-29 Akim Demaille <akim@epita.fr>
11315 * data/lalr1.cc: Reinstall the former ctor, for sake of
11316 compatibility, but warn it will be removed.
11317 Move towards a more standard C++ coding style (i.e., type *var ->
11320 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
11322 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
11323 since it's less likely to work if NULs are involved in the future.
11325 2004-09-27 Akim Demaille <akim@epita.fr>
11327 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
11329 2004-09-27 Akim Demaille <akim@epita.fr>
11331 * data/lalr1.cc (b4_parse_param_decl_1): New.
11332 (b4_parse_param_decl): Use it to have different names between attribute
11333 and argument names.
11334 (b4_cc_constructor_call): Likewise.
11336 2004-09-24 Akim Demaille <akim@epita.fr>
11338 * src/parse-gram.y (add_param): Strip the leading and trailing
11339 blanks from a formal argument declaration.
11340 (YY_LOCATION_PRINT): New.
11342 2004-09-24 Akim Demaille <akim@epita.fr>
11344 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
11345 after the location.
11347 2004-09-24 Akim Demaille <akim@epita.fr>
11349 * doc/bison.texinfo (Table of Symbols): Sort.
11351 2004-09-21 Akim Demaille <akim@epita.fr>
11353 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
11354 the useless parentheses.
11355 Suggested by Paul Eggert.
11357 2004-09-20 Akim Demaille <akim@epita.fr>
11359 Let the initial-action act on the look-ahead, and use it for the
11360 "initial push" (corresponding to an hypothetical beginning-of-file).
11361 And let lalr1.cc honor %initial-action.
11363 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
11365 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
11366 (Parser::Parser): Remove the ctor that used to initialize it.
11367 (Parser::parse): Like in the other skeletons, issue the "starting
11368 parse" message before any action.
11369 Honor %initial-action.
11370 Initialize the stacks with the lookahead.
11371 * data/yacc.c: Let $$ and @$ in %initial-action designate the
11373 Push them in the stacks.
11374 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
11376 2004-09-20 Akim Demaille <akim@epita.fr>
11378 * doc/bison.texinfo (Initial Action Decl): New.
11380 2004-09-20 Akim Demaille <akim@epita.fr>
11382 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
11383 clearer criterion to define it.
11384 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
11385 When reducing on an empty RHS, use the latest stacked location as
11387 yylloc is not always available.
11388 * data/glr.c: Likewise.
11389 Also, honor initial-actions.
11391 2004-09-20 Akim Demaille <akim@epita.fr>
11393 * data/yacc.c (YY_LOCATION_PRINT): New.
11394 Define when we know YYLTYPE's structure, i.e., when the default
11395 YYLLOC_DEFAULT is used.
11396 * data/c.m4 (b4_yysymprint_generate): Use it.
11397 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
11398 value of the result.
11399 (error_start_): Replace with...
11400 (error_range_): this location array.
11401 This allows to replace code relying on the implementation of
11402 locations by portable code.
11403 * data/yacc.c (yylerrsp): Replace with...
11404 (yyerror_range): this.
11405 Every time a token is popped, update yyerror_range[0], to have an
11406 accurate location for the error token.
11407 * data/glr.c (YY_LOCATION_PRINT): New.
11408 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
11409 deference a pointer.
11410 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
11411 report the location in %printers.
11413 * src/scan-skel.l: Instead of abort, report error messages to ease
11414 understanding skeleton scanning failures.
11416 2004-09-16 Akim Demaille <akim@epita.fr>
11418 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
11419 (iterator, const_iterator): these, to be more in the C++ spirit.
11420 Also, return reverse iterators so that when displaying the stack
11421 we display its bottom first.
11422 (Parser::stack_print_, Parser::reduce_print_): Match the messages
11424 We should probably use vector here though.
11426 2004-09-16 Akim Demaille <akim@epita.fr>
11428 Have more complete shift traces.
11430 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
11431 to report Shifts instead of ad hoc YYDPRINTF invocations,
11432 including for the error token.
11433 * data/lalr1.cc (symprint_): Output the location.
11434 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
11435 output the location within the %printer.
11436 Activate GLR tests, at least to make sure they compile properly.
11437 They still don't pass though.
11438 * tests/calc.at: Adjust expect verbose output, since now "Entering
11439 state..." is on a different line than the "Shifting" message.
11441 2004-09-08 Akim Demaille <akim@epita.fr>
11443 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
11444 Bison directive from the Bison file to the invocation of this
11445 macro, so that these directives are passed to
11446 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
11447 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
11448 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11449 the extra Bison directives instead of the whole series.
11450 Change the grammar so that there are recoverable errors, and
11451 unrecoverable errors. Now we can have the parser give up before
11452 consuming the whole input. As a result we now can observe that
11453 the lookahead is freed when needed.
11454 Change the parser source to parse argv[1] instead of a hard coded
11456 Simplify yylex, and give a value and location to EOF.
11457 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11458 passed directives already coded in the file.
11459 Add some tests to check the location of "error".
11460 For some tests, the C++ parser is correct, and not yacc.c.
11461 For other tests, they provide different, but unsatisfying, values,
11462 so keep the C++ value so that at least one parser is "correct"
11463 according to the test suite.
11464 (Actions after errors): Remove, this is subsumed by the
11465 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
11467 2004-09-06 Akim Demaille <akim@epita.fr>
11469 * data/lalr1.cc: Adjust the indentation of the labels.
11470 (Parser::pop): New.
11473 2004-09-06 Akim Demaille <akim@epita.fr>
11475 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
11476 argument, an informative message.
11477 Call YY_SYMBOL_PRINT.
11478 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
11479 * data/lalr1.cc (destruct_): Likewise.
11480 In addition, no longer depend on b4_yysymprint_generate and
11481 b4_yydestruct_generate to generate these functions, do it "by
11484 2004-09-03 Akim Demaille <akim@epita.fr>
11486 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
11487 invoked, yydestruct the lookahead.
11488 * tests/calc.at (Calculator $1): Update the expected lengths of
11489 traces: there is an added line for the discarded lookahead.
11490 * doc/bison.texinfo (Destructor Decl): Some rewording.
11491 Define "discarded" symbols.
11493 2004-09-02 Akim Demaille <akim@epita.fr>
11495 * data/lalr1.cc (translate_, destruct_): No reason to be static.
11497 2004-09-02 Akim Demaille <akim@epita.fr>
11499 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
11500 (YYDSYMPRINTF): Rename as...
11501 (YY_SYMBOL_PRINT): this.
11502 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
11504 Use it instead of direct symprint_ calls.
11505 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
11508 2004-09-02 Akim Demaille <akim@epita.fr>
11510 * data/lalr1.cc (b4_yysymprint_generate): New.
11511 (symprint_): New member function, defined when YYDEBUG.
11512 Use it consistently instead of token/nterm debugging output by
11514 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
11515 %printer calls to use cdebug_ when using lalr1.cc.
11517 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
11519 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
11520 with #ifdef YYDEBUG.
11522 2004-08-26 Akim Demaille <akim@epita.fr>
11524 * doc/bison.texinfo (Implementing Loops): Rename as...
11525 (Implementing Gotos/Loops): this.
11527 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
11529 Adjust to latest gnulib.
11530 * bootstrap (gnulib_modules): Add xalloc-die.
11531 Set LC_ALL=C so that file names sort consistently.
11532 Prefer the gnulib copies of gettext.m4, glibc21.m4,
11533 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
11534 uintmax_t.m4, ulonglong.m4.
11535 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
11536 po.m4 since we are now using _gl.m4 instead.
11538 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
11540 * src/scan-action.l: Remove. Scanning of semantic actions is
11541 handled in scan-gram.l.
11543 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
11545 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
11547 * src/location.h (struct): The file member is a uniqstr.
11548 (equal_boundaries): Use UNIQSTR_EQ for comparison.
11550 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
11552 Fix bug with non-%union parsers that have printers or destructors,
11553 which led to a Bison core dump. Reported by Peter Fales in
11554 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
11556 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
11557 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
11558 not to our own type.
11559 * src/output.c (symbol_destructors_output, symbol_printers_output):
11560 Don't assume %union.
11561 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
11562 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
11563 UNION-FLAG. All callers changed.
11564 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
11565 Use type char, not unsigned int, when declaring an array of char;
11566 this lets us remove a cast.
11567 (Printers and Destructors): Add non-%union test cases.
11569 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11571 * doc/bison.texinfo: Minor editorial changes, mostly to the new
11572 GLR writeups. E.g., avoid frenchspacing and the future tense,
11573 change "lookahead" to "look-ahead", and change "wrt" to "with
11576 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11578 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
11579 New sections, split off from the GLR Parsers section. Put the new
11580 Simple GLR Parser near the start of the GLR section, for clarity.
11581 Rewrite connective text.
11583 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
11585 * doc/bison.texinfo (Simple GLR Parsers): New section.
11587 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11589 * NEWS, TODO, doc/bison.texinfo:

11621 * tests/atlocal.in (CXXFLAGS): Use it.
11623 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>

11639 C++ compiler. (trivial change)
11641 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
11643 Spent a few hours checking out which prerequisite versions the
11644 current sources actually require. I went all the way back to
11645 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
11646 a seemingly endless set of combinations of versions more recent
11647 than that. The bottom line is that the current sources require
11648 fairly recent versions of the build tools, and it'll be some work
11650 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
11651 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
11652 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
11653 Add comments explaining why those particular versions are

11657 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
11658 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
11660 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
11661 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
11663 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11665 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
11666 0.11.5. Suggested by Bruno Haible.
11667 * bootstrap: Remove gettext version checking.
11669 * doc/bison.texinfo (Decl Summary): Also mention that %union
11670 can depend on prerequisite types. Problem reported by Tim
11673 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11675 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
11676 * README-alpha: Don't tell people not to package this.
11678 * bootstrap: Don't assume $(...) works; use `...` instead.
11679 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
11682 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
11683 put into the -d output file, and mention what to do if YYSTYPE is
11684 defined as a macro.
11686 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11688 Undo change made earlier today: it caused autopoint to not bring
11689 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
11692 * bootstrap: Check that gettext version matches what's in
11693 configure.ac. Warn users to ignore robots.txt ERROR 404.
11694 * bootstrap: Undo today's earlier change (logged below).
11695 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
11697 The gettext version checking is causing more trouble than it's
11698 curing; remove it. Problem reported by Paul Hilfinger.
11700 * bootstrap: Issue a warning that one can expect a message
11701 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
11702 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
11704 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
11706 Ensure that the C++ compiler used for testing actually works on a
11707 simple test program; if not, skip the C++-related tests. Problem
11708 reported by Vin Shelton in:
11709 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

11718 * data/glr.c (yylloc): Output this macro even if locations are not
11719 being generated, as the GLR parser needs it even in that case.
11720 Problem reported by Troy A. Johnson
11721 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
11723 * configure.ac (AC_INIT): Update to 1.875e.

11729 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
11731 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
11732 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
11733 lalr1.cc runs afoul of the first, and the last two are no longer
11734 supported by GCC 3.4.0.
11735 * README: Mention GNU m4 1.4 or later; mention m4 patches.
11736 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
11738 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
11740 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

11763 Remove more 'intl'-related files.
11764 Don't DEFUN AM_INTL_SUBDIR twice.
11766 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,

11774 * src/.cvsignore: Add *.output.
11776 * src/parse-gram.y: Put copyright notice inside %{ %} so it
11777 gets copied to the output file.
11779 2004-04-28 Paul Eggert <eggert@twinsun.com>
11781 Get files from the gnulib and po repositories, instead of relying
11782 on them being in our CVS. Upgrade to latest versions of gnulib
11785 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
11786 * bootstrap: Bootstrap from gnulib and po repositories.
11787 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11788 * README-cvs: Document these changes. Remove version numbers from
11789 mentions of build tools, since they change so often. Mention Flex.
11791 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
11792 (gl_USE_SYSTEM_EXTENSIONS): Add.
11793 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
11794 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
11796 (AC_ISC_POSIX): Remove; we no longer support this
11797 ancient OS, as it gets in the way of latest Autoconf & gnulib.
11798 (AC_HEADER_STDC): Remove: we now assume C89 or better.
11799 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
11800 Do not check for C89 headers, except for locale.h which is used
11801 by the Yacc library and must port to K&R hosts.
11802 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
11803 Do not check for C89 functions, except for setlocale which is
11804 used by the Yacc library.

11810 AM_GNU_GETTEXT): Remove; now done by:
11811 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
11812 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
11815 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
11816 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
11817 Define to empty, as gnulib.mk will do the rest for us.

11821 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
11823 * src/files.c: Include gnulib's xstrndup.h.
11825 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
11826 (REALLOC): Use xnrealloc, for likewise.
11827 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
11828 (strnlen, memrchr): Remove decls; functions no longer used.
11829 Include <stpcpy.h>.

11851 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
11852 Remove, as these files are now generated automatically
11853 by bootstrap or automake.
11855 * po/ChangeLog: Remove: all but one entry was a duplicate
11856 of this file, and I moved that 2000-11-02 entry here.

11879 support it. (The latest stable gzip doesn't.)
11881 2004-04-27 Paul Eggert <eggert@twinsun.com>
11883 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
11884 case, as stos_ is now used by destructors due to the 2004-02-09
11887 Remove more K&R C support.
11888 * lib/libiberty.y (PARAMS): Remove. All uses removed.

11899 unconditionally. Do not declare perror.
11900 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
11903 * src/complain.c (_): Remove useless defn, as system.h defines this.
11905 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
11906 with latest obstack.h.
11907 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
11908 to procedure types, as obstack.h now does that for us.
11909 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
11911 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
11912 so that this include file can stand alone.
11913 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
11914 does this now. Include subpipe.h first after config.h, to
11915 test whether it can stand alone.
11917 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
11918 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
11919 unused declaration.
11921 * tests/synclines.at (%union synch line): Put a dummy member in
11922 the union, because empty unions aren't allowed in C. Caught
11925 2004-04-13 Jim Meyering <jim@meyering.net>
11927 * src/conflicts.c (conflicts_print): Correct format string typo:

11988 Use expected_sr_conflicts in place of expected_conflicts.
11989 Warn if expected_rr_conflicts used in non-GLR parser.
11991 * doc/bison.texinfo: Add documentation for %expect-rr.
11993 2004-03-08 Paul Eggert <eggert@gnu.org>
11995 Add support for hex token numbers. Suggested by Odd Arild Olsen in
11996 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
11998 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor

12010 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
12011 compilers. This fixes a problem with Intel's C++ compiler being
12012 chatty, reported by Guido Trentalancia in
12013 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
12015 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>

12029 token so that it covers all the discarded tokens.
12030 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
12031 it can be called with `%skeleton "lalr1.cc"', and do that.
12033 2004-02-02 Paul Eggert <eggert@twinsun.com>
12035 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
12036 $(top_srcdir)/lib and ../lib. This fixes a bug reported
12037 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
12038 There's no need to mention top_builddir since Automake does that
12040 (INCLUDES): Remove, as Automake says it's obsolescent.
12041 Contents migrated into AM_CPPFLAGS as described above.
12042 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
12044 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12046 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
12047 (yyreportSyntaxError): Handle case where lookahead token is
12050 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12052 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
12053 resulting parsers are compilable with C++.
12055 2003-12-23 Paul Eggert <eggert@twinsun.com>
12057 * config/depcomp, config/install-sh: Sync with Automake 1.8.
12058 * src/output.c (output_skeleton): Rename local var.
12059 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
12060 Bison tokens, as this runs afoul of the 2003-10-07 change that
12061 disallowed NUL bytes in character constants or string literals.
12063 * tests/local.at: Require Autoconf 2.59's Autotest.
12064 * tests/testsuite.at: Don't include local.at, since we now assume
12065 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
12067 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
12068 multiple inclusion warnings.

12082 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
12083 if testsuite doesn't exist.
12085 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
12086 literals, unfortunately.
12087 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
12088 Complain about NUL bytes in character constants or string literals.
12090 2003-10-05 Paul Eggert <eggert@twinsun.com>
12092 * NEWS: Don't document %no-default-prec, as it's still
12094 * doc/bison.texinfo: Document %no-default-prec only if
12095 the defaultprec flag is set. Normally it's not.
12097 2003-10-04 Paul Eggert <eggert@twinsun.com>
12099 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
12100 non-modifiable lvalue, instead of a modifiable one.
12101 * doc/bison.texinfo (Actions): Document that $$ can
12102 be assigned to. Do not claim that $$ and $N are
12103 array element references: user code should not rely on this.

12117 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
12118 * src/print_graph.c (print_graph): Adjust.
12120 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
12121 and Paul Eggert <eggert@twinsun.com>

12141 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
12144 2003-08-26 Akim Demaille <akim@epita.fr>
12146 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
12147 "<\#" to avoid magic from Gnus when posting parts of this script.
12149 2003-08-26 Akim Demaille <akim@epita.fr>
12151 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
12152 (Parser::parse): here.
12153 Adjust: nerrs and errstatus is now replaced by...
12154 (Parser::nerrs_, Parser::errstatus_): New.
12156 2003-08-25 Akim Demaille <akim@epita.fr>
12158 * config/announce-gen, Makefile.cfg: New.
12159 * Makefile.am: Adjust.
12160 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
12161 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
12163 2003-08-25 Akim Demaille <akim@epita.fr>
12165 When reducing initial empty rules, Bison parser read an initial
12166 location that is not defined. This results in garbage, and that
12167 affects Bison's own parser. Therefore we need (i) to extend Bison
12168 to support a means to initialize this location, and (ii) to use
12169 this CVS Bison to fix CVS Bison's parser.
12171 * src/reader.h, reader.c (epilogue_augment): Remove, replace
12173 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
12174 * src/parse-gram.y: Adjust.
12175 (%initial-action): New.
12176 (%error-verbose): Since we require CVS Bison, there is no reason
12178 * src/scan-gram.l: Adjust.
12179 * src/Makefile.am (YACC): New, to make sure we use our own parser.
12180 * data/yacc.c (yyparse): Use b4_initial_action.
12182 2003-08-25 Akim Demaille <akim@epita.fr>
12184 * doc/bison.texinfo: Don't promote stdout for error messages.
12186 2003-08-25 Akim Demaille <akim@epita.fr>
12188 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
12189 From Alexandre Duret-Lutz.
12191 2003-08-25 Akim Demaille <akim@epita.fr>
12195 2003-08-25 Akim Demaille <akim@epita.fr>
12197 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
12200 2003-08-25 Akim Demaille <akim@epita.fr>
12202 * data/lalr1.cc (Parser::reduce_print_): New.
12205 2003-08-25 Akim Demaille <akim@epita.fr>
12207 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
12208 error recovery loops. This patch is based on
12209 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
12210 Also, augment the similarity between lalr1.cc and yacc.c.
12211 Note: the locations of error recovery rules are not correct yet.
12213 * data/lalr1.cc: Comment changes to augment the similarity between
12214 lalr1.cc and yacc.c.
12215 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
12216 (yyerrlab1): Remove, but where it used to be (now the bottom part of
12217 yyerrlab), when hitting EOF, pop the whole stack here instead of
12218 merely falling thru the default error handling mechanism.
12219 (yyerrorlab): New label, with the old contents of YYERROR,
12220 plus the following change: pop the stack of rhs corresponding
12221 to the production that invoked YYERROR. That is how Yacc
12222 behaves (required by POSIX).
12223 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
12226 2003-08-25 Akim Demaille <akim@epita.fr>
12228 Tune local.at so that people can "autom4te -l autotest calc.at -o
12229 calc" for instance, to extract a sub test suite.
12231 * tests/testsuite.at: Move the initialization, Autotest version
12232 requirement, and AT_TESTED invocation into...
12233 * tests/local.at: here.
12234 * tests/testsuite.at: Include it for compatibility with Autoconf
12236 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
12239 2003-08-04 Paul Eggert <eggert@twinsun.com>
12241 Rework code slightly to avoid gcc -Wtraditional warnings.
12242 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
12243 The returned value is now stored in *YY0. All callers changed.
12244 * src/output.c (merge_output): Adjust to the above change.
12246 2003-07-26 Paul Eggert <eggert@twinsun.com>
12248 * data/glr.c (YYASSERT): New macro.
12249 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
12250 yyresolveStates, yyprocessOneStack):
12251 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
12252 Derived from a suggestion by Frank Heckenbach.
12254 2003-07-25 Paul Eggert <eggert@twinsun.com>
12256 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
12257 for portability to K&R C (after ansi2knr, presumably). See
12258 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
12259 by Frank Heckenbach, though I have omitted the structure-initialization
12260 part of his glr-knr.diff patch since I recall that the Portable
12261 C Compiler didn't require that change.
12263 Let the user specify how to allocate and free memory.
12264 Derived from a suggestion by Frank Heckenbach in
12265 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
12266 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
12267 All uses of free, malloc, realloc changed to use these macros,
12268 and unnecessary casts removed.
12269 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
12271 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
12273 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
12274 use s.empty() rather than s == "" to test for empty string; see
12275 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
12278 2003-06-25 Akim Demaille <akim@epita.fr>
12280 * config/depcomp, config/install-sh: Update from masters.
12282 2003-06-20 Paul Eggert <eggert@twinsun.com>
12284 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
12285 and return properly parenthesized result.
12286 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
12287 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
12288 Remove unnecessary parentheses from uses.

12290 conventions for parentheses.
12292 2003-06-19 Paul Eggert <eggert@twinsun.com>
12294 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
12295 yyreportTree): Do not assume that size_t is the same width as int,
12296 when printing sizes. Print sizes using an unsigned format.
12297 Problem reported by Frank Heckenbach in
12298 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
12300 Port to Forte Developer 7 C compiler.
12301 * data/glr.c (struct YYLTYPE): If locations are not being used,
12302 declare a single dummy member, as empty structs do not conform
12304 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
12305 the Forte Developer 7 C compiler complains that end-of-loop
12306 code is not reached.
12308 2003-06-17 Paul Eggert <eggert@twinsun.com>
12310 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
12311 avoid warnings from picky compilers about redefinition of PARAMS.
12313 2003-06-17 Paul Eggert <eggert@twinsun.com>
12317 * NEWS: Document 1.875b.
12319 * lib/bbitset.h: Do not include config.h; that's the includer's job.
12320 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
12321 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
12322 Don't use 'index' in comments, as it's a builtin fn on some hosts.
12323 * lib/bitset_stats.c: Include gettext.h unconditionally, as
12324 per recent gettext manual's suggestion.
12325 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
12326 Use prototypes, not old-style definitions.

12342 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
12343 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
12344 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
12345 * lib/vbitset.c, lib/vbitset.h: New files.
12346 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
12347 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
12350 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
12351 `How Can I Reset @code{yyparse}', since texinfo does not allow
12352 arbitrary @ in node names.
12354 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
12355 shouldn't be needed according to the gettext 0.12.1 documentation
12356 but which seem to be needed anyway: codeset.m4 glibc21.m4
12357 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
12358 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

12364 Upgrade to CVS gnulib.
12365 * stdbool_.h: File renamed from stdbool.h.in.
12366 * configure.ac (AM_STDBOOL_H): Invoke this instead of
12368 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
12369 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
12370 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
12371 (MOSTLYCLEANFILES): New var.

12379 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
12380 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
12381 the tests right now.
12382 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
12383 yyerror are declared before use; C99 requires this.
12385 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12387 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
12389 (yyrecoverSyntaxError): Correct the logic for setting and testing
12391 Correct comment on handling EOF.
12392 Allow states with only a default reduction, rather than failing
12393 (I can't quite reconstruct why these were not allowed before).
12395 Fixes to avoid problem that $-N rules in GLR parsers can cause
12396 buffer overruns, corrupting state.
12398 * src/output.c (prepare_rules): Output max_left_semantic_context
12400 * src/reader.h (max_left_semantic_context): New variable declaration.
12401 * src/scan-gram.l (max_left_semantic_context): Define.
12402 (handle_action_dollar): Update max_left_semantic_context.

12404 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
12405 (yyresolveAction): Ditto.
12407 Fixes to problems with location handling in GLR parsers reported by
12408 Frank Heckenbach (2003/06/05).
12410 * data/glr.c (YYLTYPE): Make trivial if locations not used.
12411 (YYRHSLOC): Add parentheses, and define only if locations used.
12412 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
12413 locations not used.
12414 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
12415 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
12417 * tests/cxx-type.at: Exercise location information; update tests
12418 to differentiate output with and without locations.
12419 Remove forward declarations of yylex and yyerror---caused errors
12420 because default YYLTYPE not yet defined.
12421 Change semantic actions to compute strings, rather than printing
12422 them directly (to test proper passing of semantics values). Change
12423 output to prefix notation and update test data and expected results.
12424 (yylex): Track locations.
12425 (stmtMerge): Return value rather than printing, and include arguments
12428 2003-06-03 Paul Eggert <eggert@twinsun.com>
12430 Avoid warnings generated by GCC 2.95.4 when Bison is
12431 configured with --enable-gcc-warnings.
12432 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,

12435 yy::Stack::operator[] (unsigned) const,
12436 yy::Slice::operator[] (unsigned),
12437 yy::Slice::operator[] (unsigned) const):
12438 Rename local vars to avoid warnings.
12439 * tests/glr-regression.at (Improper handling of embedded actions
12440 and $-N in GLR parsers): Remove unused local variable from yylex.
12441 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
12442 (void) as arg when not pure, since we now assume C89 when building
12443 Bison. Pacify GCC by using parameter.
12445 2003-06-02 Paul Eggert <eggert@twinsun.com>
12447 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
12448 yy::Location::lines, yy::Location::columns): Rename arguments
12449 to avoid shadowing; this removes a warning generated by GCC 3.3.
12451 2003-06-01 Paul Eggert <eggert@twinsun.com>
12453 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
12454 to g++, as GCC 3.3 complains if you do it.
12455 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
12456 everything that WARNING_CFLAGS has, except omit warnings
12457 not suitable for C++.
12458 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
12459 * tests/atlocal.in (CXXFLAGS): New var.
12460 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
12462 Fix a GLR parser bug I reported in February; see
12463 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
12464 The problem was that GLR parsers did not conform to the C standard,
12465 because actions like { $1 = $2 + $3; } expanded to expressions
12466 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12467 to a local variable. The C standard says that expressions
12468 like (var = f ()) + (var = f ()) have undefined behavior.
12469 Another problem was that GCC sometimes issues warnings that
12470 yyfill and its parameters are unused.
12472 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12473 as possibly unused.
12474 (yyfill): New function.
12476 (yyuserAction): Change type of yynormal to bool, so that it matches
12477 the new yyfill signature. Mark it as possibly unused.
12480 Follow up on a bug I reported in February, where a Bison-generated
12481 parser can loop. Provide a test case and a fix for yacc.c. I
12482 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12483 The original bug report is in:
12484 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
12486 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12487 macro's size was becoming unwieldy.
12488 (yyerrlab): Do not discard an empty lookahead symbol, as this
12489 might destroy garbage.
12490 (yyerrorlab): New label, with the old contents of YYERROR,
12491 plus the following change: pop the stack of rhs corresponding
12492 to the production that invoked YYERROR. That is how Yacc
12493 behaves, and POSIX requires this behavior.
12494 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12495 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12496 Define 'alarm' to do nothing if unistd.h is not available.
12497 Add a new rule "exp: '-' error;" to test the above change to
12498 data/yacc.c. Use 'alarm' to abort any test taking longer than
12499 10 seconds, as it's probably looping.
12500 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12501 Also, the new yacc.c generates two fewer diagnostics for an
12504 2003-05-24 Paul Eggert <eggert@twinsun.com>
12506 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
12507 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
12508 This fixes a problem reported by John Bowman when the Compaq/HP
12509 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
12510 -ansi -Wall -gall).
12511 * data/yacc.c (union yyalloc): Likewise.
12512 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
12514 Switch from 'int' to 'bool' where that makes sense.

12594 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
12596 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
12597 parse-param arguments.
12598 (yy::b4_parser_class_name): Declare instance variables to
12599 hold parse-param arguments.
12600 * tests/calc.at: s/value/semantic_value/ because value clashes
12601 with a member of yy::b4_parser_class_name. Adjust C++ code
12602 to handle %parse-param. Enable %parse-param test in C++.
12604 2003-05-12 Paul Eggert <eggert@twinsun.com>
12606 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
12607 English a bit. Fix fclose typo. Change "const char" to "char
12608 const", and use ANSI C rather than K&R for "main". Suggest
12609 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
12610 and suggest yy_switch_to_buffer.
12612 2003-05-05 Paul Eggert <eggert@twinsun.com>
12614 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
12615 C89. This avoids a diagnostic on compilers that define __STDC__
12616 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
12617 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12619 2003-05-03 Paul Eggert <eggert@twinsun.com>
12621 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
12622 Do not overrun array bounds.
12623 This should fix a bug reported today by Olatunji Oluwabukunmi in
12624 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
12626 2003-04-29 Akim Demaille <akim@epita.fr>
12628 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
12629 * src/getargs.c, src/getargs.h: here, as bool, not int.
12630 (nondeterministic_parser): New.
12631 * src/parse-gram.y, src/scan-gram.l: Support
12632 %nondeterministic-parser.
12633 * src/output.c (prepare): Use nondeterministic_parser instead
12634 of glr_parser where appropriate.
12635 * src/tables.c (conflict_row, action_row, save_row)
12636 (token_actions, token_actions, pack_vector): Ditto.
12638 2003-04-29 Akim Demaille <akim@epita.fr>
12640 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
12642 2003-04-29 Akim Demaille <akim@epita.fr>
12644 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
12645 with %pure-parser and %locations to exercise the patch from Yakov
12648 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
12650 * data/yacc.c: (b4_lex_param): Corrected for the case where
12651 %lex-param is provided and %pure-parser isn't.
12653 2003-04-27 Paul Eggert <eggert@twinsun.com>
12655 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
12656 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
12657 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
12658 if it is not defined.
12659 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
12661 2003-04-26 Paul Eggert <eggert@twinsun.com>
12663 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
12664 Declare to be of type suitable for the ninf value itself, not of
12665 type suitable for the corresponding table, since the latter might
12666 be unsigned but the ninf value might be negative. This fixes a
12667 bug reported by Alexandre Duret-Lutz in
12668 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
12670 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
12671 invokes it. We shouldn't invoke it twice because it will attempt
12672 to put error.o in the archive twice. This fixes a glitch reported
12673 by Martin Mokrejs in
12674 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12676 2003-04-21 Paul Eggert <eggert@twinsun.com>
12678 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
12681 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
12683 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
12684 Fix obvious typo that results in uncompilable GLR parsers
12685 when both %pure-parser and %locations are used. (trivial change)
12687 2003-04-17 Paul Eggert <eggert@twinsun.com>
12689 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
12690 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
12691 Do not insert the expected token via unput, as this runs afoul
12692 of a POSIX-compatibility bug in flex 2.5.31.
12693 All uses changed to BEGIN the parent state,
12694 since we no longer insert the expected token via unput.
12695 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
12696 that is no longer emitted after the above change.
12698 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
12699 the first one. This change is from Paul Hilfinger, and it fixes
12700 regression reported by Werner Lemberg in
12701 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
12703 (resolve_sr_conflict): Don't invoke state_errs_set
12704 unless one or more tokens have been explicitly made errors.
12705 Otherwise, the above change causes Bison to abort.
12707 * tests/existing.at (GNU pic Grammar): New test case, taken from
12710 2003-03-31 Akim Demaille <akim@epita.fr>
12712 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
12714 2003-03-31 Akim Demaille <akim@epita.fr>
12716 * src/output.c (prepare_symbols): Avoid trailing spaces in the
12719 2003-03-31 Akim Demaille <akim@epita.fr>
12721 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
12722 From Paul Hilfinger.
12724 2003-03-29 Akim Demaille <akim@epita.fr>
12726 * m4/error.m4: Do not put under dynamic conditions some code which
12727 expansion is under static control.
12729 2003-03-29 Akim Demaille <akim@epita.fr>
12731 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
12733 2003-03-29 Akim Demaille <akim@epita.fr>
12735 * doc/bison.texinfo (Strings are Destroyed): New.
12737 2003-03-13 Paul Eggert <eggert@twinsun.com>
12739 * .cvsignore: Add configure.lineno.
12740 * src/.cvsignore: Add yacc.
12741 * tests/.cvsignore: Add testsuite.log.
12742 * doc/fdl.texi: Sync with latest FSF version.
12744 2003-03-12 Paul Eggert <eggert@twinsun.com>
12746 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
12747 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
12748 cursor, instead of leaving it undefined. This fixes a bug
12749 reported by Tim Van Holder in
12750 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
12751 * tests/input.at (Torturing the Scanner): Test the scanner on
12752 an empty input file, which was Tim Van Holder's test case.
12754 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
12755 <sys/resource.h> can be included, include sys/time.h and
12756 sys/times.h first, if available. This works around the SunOS
12757 4.1.4 porting bug reported by Bruce Becker in
12758 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
12760 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
12761 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
12762 AC_HEADER_SYS_WAIT.
12764 Merge changes from gnulib. This was prompted because the CVS
12765 snapshot didn't build on Solaris 7 due to strnlen problems.
12767 These changes need to be merged back into gnulib:
12768 * lib/hash.c: Include <stdbool.h> unconditionally.
12769 * m4/onceonly.m4 (m4_quote): New macro.
12770 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
12771 Quote AC_FOREACH variable-expansions properly.
12772 The 2003-01-03 obstack.h change also needs merging.
12773 {end of changes requiring merging}
12775 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
12776 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
12777 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
12778 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
12779 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
12780 New files, imported from gnulib.
12781 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
12784 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
12785 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
12788 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
12790 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
12791 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
12792 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
12793 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
12794 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
12795 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
12796 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
12797 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
12798 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
12799 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
12800 (jm_PREREQ_ARGMATCH): Remove.
12801 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
12802 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
12804 * src/system.h: Include <stdbool.h> unconditionally.
12806 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
12807 assuming at least C89 in the bitset code for some time now.
12809 2003-03-03 Akim Demaille <akim@epita.fr>
12813 2003-03-02 Akim Demaille <akim@epita.fr>
12815 * doc/bison.texinfo (Table of Symbols): Reactivate the
12816 documentation for %lex-param, and %parse-param.
12818 2003-03-02 Akim Demaille <akim@epita.fr>
12820 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
12821 generate verbose error messages.
12822 Use the number of tokens as an upper bound in yytname, as it
12823 cannot be a non terminal.
12825 2003-03-02 Akim Demaille <akim@epita.fr>
12827 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
12830 2003-03-02 Akim Demaille <akim@epita.fr>
12832 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
12833 Use them to exercise yycheck overrun.
12834 Based on Andrew Suffield's grammar.
12836 2003-03-02 Akim Demaille <akim@epita.fr>
12838 Create tests/local.at for Bison generic testing macros.
12840 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
12841 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
12843 * tests/calc.at (AT_CHECK_CALC): Adjust.
12844 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
12845 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
12846 * tests/local.at: here.
12847 (AT_COMPILE_CXX): Tags the tests using it as c++.
12848 Ignore the test if CXX is not functional.
12850 2003-03-01 Paul Eggert <eggert@twinsun.com>
12852 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12853 not loc->end, since loc->end might contain garbage and this leads
12854 to undefined behavior on some platforms.
12855 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12856 depend on *loc, so that the reader doesn't give the the false
12857 impression that *loc is initialized.
12858 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12859 does not survive the return.
12861 2003-03-01 Akim Demaille <akim@epita.fr>
12863 * src/scan-gram.l (code_start): Always initialize it when entering
12864 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12865 yylex invocation. An alternative would be making it static, but
12866 then it starts with the second %%'s beginning, instead of its end.
12868 2003-02-28 Paul Eggert <eggert@twinsun.com>
12870 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12871 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12872 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12874 2003-02-26 Paul Eggert <eggert@twinsun.com>
12876 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12877 Remove Sequent/Pyramid discussion (nobody uses them any more).
12878 Merge VMS and MS-DOS discussion; these ports may well be dead
12879 but let's keep mentioning them for now. Put <> around email
12880 addresses. Add copyright notice.
12882 2003-02-24 Paul Eggert <eggert@twinsun.com>
12884 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12885 to avoid collision with flex use of yylineno.
12886 Problem reported by Bruce Lilly in
12887 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
12888 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
12889 * data/yacc.c (yy_reduce_print): Likewise.
12891 * config/depcomp: Sync with Automake 1.7.3.
12893 2003-02-21 Akim Demaille <akim@epita.fr>
12895 * data/lalr1.cc: Use temporary variables instead of casts to
12896 change integer types.
12897 Suggested by Paul Eggert.
12899 2003-02-21 Akim Demaille <akim@epita.fr>
12901 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12902 to avoid confusions with lalr1.cc's notion of Position.
12903 Suggested by Paul Eggert.
12905 2003-02-20 Akim Demaille <akim@epita.fr>
12907 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12908 before initial_columns.
12909 (location.hh): Use consistent variable names when defining the
12911 Use "last" so that we subtract from Positions, not from unsigned.
12913 2003-02-20 Akim Demaille <akim@epita.fr>
12915 * data/lalr1.cc (position.hh): New subfile, including the extended
12916 and Doxygen'ed documentation of class Position.
12917 (location.hh): Use it.
12918 Document a` la Doxygen.
12919 With the help of Benoit Perrot.

12925 Redefine AT_YYERROR_SEES_LOC_IF using it.
12926 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
12928 Don't use the location in yy::Parser::error_ and
12929 yy::Parser::print_ when not %locations.
12930 Activate more lalr1.cc tests.
12932 2003-02-19 Akim Demaille <akim@epita.fr>
12934 * data/lalr1.cc: When displaying a line number, be sure to make it
12937 2003-02-19 Akim Demaille <akim@epita.fr>
12939 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12941 (YYABORT, YYACCEPT, YYERROR): New.
12942 * tests/calc.at: Renable the lalr1.cc test.
12944 2003-02-19 Akim Demaille <akim@epita.fr>
12946 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12947 error recovery, mixing with/without pops and discarding of the
12950 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
12952 2003-02-17 Paul Eggert <eggert@twinsun.com>
12954 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
12955 * tests/testsuite.at (AT_COMPILE): Use them.
12956 This fixes the testsuite problem reported by Robert Lentz in
12957 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
12959 2003-02-12 Paul Eggert <eggert@twinsun.com>
12961 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
12962 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
12963 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
12964 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12965 Check for malloc failure, for consistency with yacc.c.
12966 (yytname_size): Remove, for consistency with yacc.c.
12968 The bug still remains in data/lalr1.cc, as I didn't have time
12971 2003-02-06 Akim Demaille <akim@epita.fr>
12973 * configure.ac (GXX): Rename as...
12974 (CXX): this, to keep the original Autoconf semantics.
12976 * data/lalr1.cc: Fix b4_copyright invocations.
12977 If YYDEBUG is not defined, don't depend upon name_ being defined.
12978 (location.hh): Include string and iostream.

12989 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
12990 locations in a more synthetic way.
12991 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
12993 Adjust the C locations to match those from Emacs: first column is
12995 Change all the expected results.
12996 Conform to the GCS: simplify the locations when applicable.
12997 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
12998 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
12999 these CPP macros with the m4 macros new defined by...
13000 (AT_CHECK_PUSHDEFS): this, i.e.:
13001 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)

13004 (AT_CHECK_POPDEFS): Undefine them.
13005 (AT_CHECK_CALC_LALR1_CC): New.

13010 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
13011 Location as is defined.
13013 2003-02-04 Akim Demaille <akim@epita.fr>
13015 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
13016 name_ being defined.
13018 2003-02-03 Paul Eggert <eggert@twinsun.com>
13020 * src/gram.h (start_symbol): Remove unused decl.
13022 Use more-consistent naming conventions for local vars.
13024 * src/derives.c (derives_compute): Change type of local var from
13025 int to rule_number.
13026 * src/gram.c (grammar_rules_partial_print): Likewise.

13039 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
13041 * src/state.c (transitions_to): Likewise.
13042 * src/state.h: Likewise.
13043 * src/tables.c (symbol_number_to_vector_number): Likewise.
13045 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
13048 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
13051 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
13054 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
13055 Use str, not s, for char * var. Use ch, not c, for character var.
13056 Use size for size var.
13058 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
13060 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
13062 * src/uniqstr.h: Likewise.
13064 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13065 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13066 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
13067 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
13068 param to have same name as that of enum, so that we don't use
13069 "s" to stand for a non-state.
13071 2003-02-02 Akim Demaille <akim@epita.fr>
13073 * src/scan-skel.l: Scan more than one inert character per yylex
13076 2003-02-01 Paul Eggert <eggert@twinsun.com>
13080 * po/LINGUAS: Add ms.
13082 2003-01-30 Akim Demaille <akim@epita.fr>
13084 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
13086 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13088 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
13091 Changes in response to error report by S. Eken: GLR mode does not
13092 handle negative $ indices or $ indices in embedded rules correctly.
13093 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
13095 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
13096 (b4_rhs_location): Ditto.
13097 (yyfill): New function to copy from stack tree into array
13099 (yyuserAction): Modify to allow incremental move of semantic values
13100 to rhs array when in GLR mode.
13101 Define YYFILL to use in user-defined actions to fill semantic array
13103 Remove dummy use of yystack, as there is now a guaranteed use.
13104 (yydoAction): Modify to allow incremental move of semantic values
13105 to rhs array when in GLR mode.
13106 (yyresolveAction): Ditto.
13107 (yyglrShiftDefer): Update comment.
13108 (yyresolveStates): Use X == NULL for pointers, not !X.
13109 (yyglrReduce): Ditto.
13110 (yydoAction): Ditto
13112 * tests/glr-regr1.at: Rename to ...
13113 * tests/glr-regression.at: Add new regression test for the problems
13114 described above (adapted from S. Eken).
13115 Update copyright notice.
13116 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
13117 * tests/Makefile.am: Ditto.
13119 2003-01-28 Paul Eggert <eggert@twinsun.com>
13121 * data/lalr1.cc: Do not use @output_header_name@ unless
13122 b4_defines_flag is set. This fixes two bugs reported by
13124 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
13125 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
13127 2003-01-21 Paul Eggert <eggert@twinsun.com>
13129 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
13130 we don't need to worry about yyerrlab1 being reported as an
13131 "unused label" by non-GCC C compilers. The downside is that if
13132 locations are used then a couple of statements are duplicated each
13133 time YYERROR is invoked, but the upside is that the warnings
13135 (yyerrlab1): Move code to YERROR.
13136 (yyerrlab2): Remove. Change uses back to yyerrlab1.
13137 This reverts some of the 2002-12-27 change.
13139 2003-01-17 Paul Eggert <eggert@twinsun.com>
13141 * src/output.c (symbol_printers_output): Fix typo that led
13142 to core dump. Problem reported by Antonio Rus in
13143 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
13145 2003-01-13 Akim Demaille <akim@epita.fr>,
13146 Quoc Peyrot <chojin@lrde.epita.fr>,
13147 Robert Anisko <anisko_r@lrde.epita.fr>
13149 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
13150 when the stacks contain one element, as the loop would otherwise
13151 free the last state, and then use the top state (the one we just
13152 popped). This means that the initial elements will not be freed
13153 explicitly, as is the case in yacc.c; it is not a problem, as
13154 these elements have fake values.
13156 2003-01-11 Paul Eggert <eggert@twinsun.com>
13158 * NEWS: %expect-violations are now just warnings, reverting
13159 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
13160 bootstrapping problem reported by Matthias Klose; see
13161 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
13162 * src/conflicts.c (conflicts_print): Likewise.
13163 * tests/conflicts.at (%expect not enough, %expect too much,
13164 %expect with reduce conflicts): Likewise.
13165 * doc/bison.texinfo (Expect Decl): Document this. Also mention
13166 that the warning is enabled if the number of conflicts changes
13167 (not necessarily increases).
13169 * src/getargs.c (version): Update copyright year.
13171 2003-01-09 Akim Demaille <akim@epita.fr>
13173 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
13175 2003-01-08 Paul Eggert <eggert@twinsun.com>
13177 * Makefile.maint (WGETFLAGS):
13178 New macro, containing "-C off" to disable proxy caches.
13179 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
13180 (rel-check): Use $(WGET) instead of wget.
13182 2003-01-06 Paul Eggert <eggert@twinsun.com>
13184 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
13185 the GLR paper of Scott, Johnstone and Hussain.
13187 2003-01-04 Paul Eggert <eggert@twinsun.com>
13189 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
13190 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
13191 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
13192 (EXTRA_LIBRARIES): New var, for liby.a.
13193 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
13194 (EXTRA_SCRIPTS): New var, for yacc.
13196 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
13197 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
13198 Problem reported by Nelson H. F. Beebe.
13200 2003-01-03 Paul Eggert <eggert@twinsun.com>
13202 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
13203 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
13204 when compiling Bison 1.875's `bitset bset = obstack_alloc
13205 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
13207 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
13208 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
13209 grow to a huge size with typical invocation.
13211 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
13212 Use the pattern recommended by Autoconf 2.57, except also protect
13213 against double-definition.
13214 * src/system.h: Likewise.
13215 Portability issues reported by Nelson H. F. Beebe.
13217 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
13218 All uses changed. Provide a definition in both C and C++.
13219 (yytrue, yyfalse): Define even if defined (__cplusplus).
13221 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
13222 Reported by Nelson H. F. Beebe.
13224 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
13226 2003-01-02 Paul Eggert <eggert@twinsun.com>
13228 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
13229 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
13230 Bug reported by Nelson H. F. Beebe.
13232 2003-01-01 Paul Eggert <eggert@twinsun.com>
13236 2002-12-30 Paul Eggert <eggert@twinsun.com>
13238 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
13240 (<INITIAL>","): Here. This causes stray "," to be treated
13243 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
13244 last brace in braced code when not in Yacc mode, for compatibility
13245 with Bison 1.35. This resurrects the 2001-12-15 patch to
13248 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
13249 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
13251 2002-12-28 Paul Eggert <eggert@twinsun.com>
13253 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
13254 that of SYM's type. This fixes Debian bug 168069, reported by
13257 2002-12-28 Paul Eggert <eggert@twinsun.com>
13261 Switch back to the Yacc style of conflict reports, undoing some
13262 of the 2002-07-30 change.
13263 * doc/bison.texinfo (Understanding): Use Yacc style for
13264 conflict reports. Also, use new way of locating rules.
13265 * src/conflicts.c (conflict_report):
13266 Renamed from conflict_report_yacc, removing the old
13267 'conflict_report'. Translate the entire conflict report at once,
13268 so that we don't assume that "," has the same interpretation in
13270 (conflicts_output): Use Yacc-style conflict report for each state,
13271 instead of our more-complicated style.
13272 (conflicts_print): Use Yacc-style conflict report, except print
13273 the input file name when not emulating Yacc.
13274 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
13275 Conflicted Reduction, %expect not enough, %expect too much,
13276 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
13277 * tests/existing.at (GNU Cim Grammar): Likewise.
13278 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
13280 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
13281 fatal): Don't invoke fflush; it's not needed and it might even be
13282 harmful for stdout, as stdout might not be open.
13283 * src/reduce.c (reduce_print): Likewise.
13285 2002-12-27 Paul Eggert <eggert@twinsun.com>
13287 Fix a bug where error locations were not being recorded correctly.
13288 This problem was originally reported by Paul Hilfinger in
13289 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
13291 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13292 top of the location stack's error locations.
13293 (yyerrlab): Set it. When discarding a token, push its location
13294 onto yylerrsp so that we don't lose track of the error's end.
13295 (yyerrlab1): Now is only the target of YYERROR, so that we can
13296 properly record the location of the action that failed. For GCC
13297 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13298 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13299 (yyerrlab2): New label, which yyerrlab now falls through to.
13300 Compute the error's location by applying YYLLOC_DEFAULT to
13301 the locations of all the symbols that went into the error.
13302 * doc/bison.texinfo (Location Default Action): Mention that
13303 YYLLOC_DEFAULT is also invoked for syntax errors.
13304 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13305 Error locations include the locations of all the tokens that were
13306 discarded, not just the last token.
13308 2002-12-26 Paul Eggert <eggert@twinsun.com>
13310 * src/files.c: Include quote.h.
13311 (compute_output_file_names): Warn if we detect conflicting
13312 outputs to the same file. This should catch the misunderstanding
13313 exemplified by Debian Bug 165349, reported by Bruce Stephens..
13315 * src/conflicts.c (conflicts_print): If the user specifies
13316 "%expect N", report an error if there are any reduce/reduce
13317 conflicts. This is what the manual says should happen.
13318 This fixes Debian bug 130890, reported by Anthony DeRobertis.
13319 * tests/conflicts.at (%expect with reduce conflicts): New test.
13321 Don't use m4_include on relative file names, as it doesn't work as
13322 desired if there happens to be a file with that name under ".".
13324 * m4sugar/version.m4: Remove; it was included but it wasn't used.
13325 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
13326 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
13327 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
13328 * src/output.c (output_skeleton): Use full path names when
13329 specifying a file to include; don't rely on include path, as
13330 it's unreliable when the working file contains a file with
13333 2002-12-25 Paul Eggert <eggert@twinsun.com>
13335 Remove obsolete references to bison.simple and bison.hairy.
13336 Problem mentioned by Aubin Mahe in
13337 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
13338 * data/glr.c: Comment fix.
13339 * doc/bison.1: Remove references. Also, mention "yacc".
13341 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
13344 * src/parse-gram.y (declaration): Use enum "report_states" rather
13345 than its numeric value 1.
13347 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
13348 opening a new one. This fixes Debian bug 165349, reported by
13351 2002-12-24 Paul Eggert <eggert@twinsun.com>
13355 * Makefile.maint (cvs-update): Don't assume that the shell
13356 supports $(...), as Solaris sh doesn't.
13358 * src/parse-gram.y (lloc_default): Remove test for empty
13359 nonterminals at the end, since it didn't change the result.
13361 2002-12-24 Paul Eggert <eggert@twinsun.com>
13363 If the user does not define YYSTYPE as a macro, Bison now declares it
13364 using typedef instead of defining it as a macro. POSIX requires this.
13365 For consistency, YYLTYPE is also declared instead of defined.
13367 %union directives can now have a tag before the `{', e.g., the
13368 directive `%union foo {...}' now generates the C code
13369 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13370 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13371 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13372 instead of `yyltype'.
13374 `yystype' and `yyltype' are now obsolescent macros instead of being
13375 typedefs or tags; they are no longer documented and will be
13376 withdrawn in a future release.
13378 * data/glr.c (b4_location_type): Remove.
13379 (YYSTYPE): Renamed from yystype.
13380 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
13381 (struct YYLTYPE): Renamed from struct yyltype.
13382 (YYLTYPE): Renamed from yyltype.
13383 (yyltype, yystype): New (and obsolescent) macros,
13384 for backward compatibility.
13385 * data/yacc.c: Likewise.
13387 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13388 does not specify a union tag. This is for compatibility with
13391 * src/parse-gram.y (add_param): 2nd arg is now char * not char
13392 const *, since it is now modified by stripping surrounding { }.
13393 (current_braced_code): Remove.
13394 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
13395 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
13396 trailing " {...}". Now of type <chars>.
13397 (grammar_declaration): Adjust to bundled tokens.
13398 (code_content): Remove; stripping is now done by add_param.
13399 (print_token_value): Print contents of bundled tokens.
13400 (token_name): New function.
13402 * src/reader.h (braced_code, current_braced_code): Remove.
13403 (token_name): New decl.
13405 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
13406 token_type, not braced_code code_kind. All uses changed.
13407 (SC_PRE_CODE): New state, for scanning after a keyword that
13408 has (or usually has) an immediately-following braced code.
13409 (token_type): New local var, to keep track of which token type
13410 to return when scanning braced code.
13411 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
13412 <INITIAL>"%parse-param", <INITIAL>"%printer",
13413 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
13414 instead of returning a token type immediately.
13415 (<INITIAL>"{"): Set token type.
13416 (<SC_BRACED_CODE>"}"): Use it.
13417 (handle_action_dollar, handle_action_at): Now returns bool
13418 indicating success. Fail if ! current_rule; this prevents a core dump.
13419 (handle_symbol_code_dollar, handle_symbol_code_at):
13420 Remove; merge body into caller.
13421 (handle_dollar, handle_at): Complain in invalid contexts.
13423 * NEWS, doc/bison.texinfo: Document the above.
13424 * NEWS: Fix years and program names in copyright notice.
13426 2002-12-17 Paul Eggert <eggert@twinsun.com>
13428 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
13429 Reporting, Table of Symbols): Omit mentions of %lex-param and
13430 %parse-param from the documentation for now.
13432 2002-12-15 Paul Eggert <eggert@twinsun.com>
13434 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
13435 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
13436 lookahead symbol, and which sets yychar in parser actions) and it
13437 disagreed with the Bison documentation. Bug
13438 reported by Andrew Walrond.
13440 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
13441 as the caller now does that.
13442 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
13443 (YYEMPTY): Parenthesize right hand side, since others use it.
13444 (yyparse): Don't assume that our generated code is the only code
13447 2002-12-13 Paul Eggert <eggert@twinsun.com>
13451 POSIX requires a "yacc" command.
13452 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
13453 (MOSTLYCLEANFILES): Add yacc.
13455 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
13456 as an alias for bison y.
13458 * po/LINGUAS: Add da.
13460 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
13461 problem with latest <getopt.h>.
13462 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
13464 * doc/fdl.texi: Upgrade to 1.2.
13465 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
13466 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
13467 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
13469 * config/install-sh: Sync with autotools.
13471 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
13472 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13473 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
13474 locations are requested.
13475 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
13476 locations are requested.
13478 2002-12-12 Paul Eggert <eggert@twinsun.com>
13480 Remove unportable casts and storage allocation tricks.
13481 While we're at it, remove almost all casts, since they
13482 usually aren't needed and are a sign of trouble.
13484 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13486 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13487 the pointer DSET returned by malloc; this isn't portable.
13488 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13489 Similarly for DERIVES.
13490 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
13491 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
13492 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
13494 * src/derives.c (derives_compute): Do not bother invoking
13495 int_of_rule_number, since rule numbers are integers.
13497 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
13498 rather than XMALLOC (char, N).
13500 * src/files.c (filename_split): Rewrite to avoid cast.
13502 * src/gram.h (symbol_number_as_item_number,
13503 item_number_as_symbol_number, rule_number_as_item_number,

13533 * src/uniqstr.c (uniqstr_print_processor): Likewise.
13534 * src/muscle_tab.c (muscles_m4_output):
13535 Use new functions instead of casting old functions unportably.

13542 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13543 var instead of casting to long, to avoid casts.
13544 (prepare_states): Use MALLOC rather than alloca, so that we don't
13545 have to worry about alloca.
13546 * src/state.c (state_hash_lookup): Likewise.
13548 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
13549 local var instead of casting to unsigned char, to avoid casts.

13552 STATE_ALLOC): Remove.
13553 (transitions_new, errs_new, reductions_new, state_new): Use malloc

13566 (symbol_processor): Remove.
13567 (symbols_do): Remove decl; now static.

13571 (<inttypes.>, <stdint.h>): Include if available.
13572 (uintptr_t): New type, if system lacks it.
13573 (CALLOC, MALLOC, REALLOC): New macros.
13574 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
13577 * src/tables.c (table_size): Now int, to pacify GCC.

13590 2002-12-09 Paul Eggert <eggert@twinsun.com>
13592 Change identifier spellings to avoid collisions with names
13593 that are reserved by POSIX.
13595 Don't use names ending in _t, since POSIX reserves them.
13596 For consistency, remove _e and _s endings -- they're weren't
13597 needed to remove ambiguity. All uses changed.
13598 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
13599 turn was just renamed from struniq_t.
13600 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
13601 which in turn was just renamed from struniq_processor_t.

13673 value_t_as_yystype -> value_as_yystype.
13675 Don't include <errno.h> in the mainstream code, since it
13676 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
13677 * lib/get-errno.c, lib/get-errno.h: New files.
13678 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

13693 likewise for "STRUNIQ" and "UNIQSTR".
13694 * src/uniqstr.c: Renamed from src/struniq.c.
13695 * src/uniqstr.h: Renamed from src/struniq.h.
13696 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

13706 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.

13718 (BASE_MINIMUM): Renamed from BASE_MIN.
13719 (ACTION_MAX): Remove; unused.
13720 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
13721 Unnecessary casts removed from above defines.
13724 Fix misspelling in names.
13725 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
13726 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
13730 * lib/timevar.c (timevar_report): Renamed from time_report,
13731 for consistency with other names.
13732 * lib/timevar.h (timevar_report): New decl.
13733 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
13736 Sort include-file uses.
13738 Reorder all include files under src to be in the order "system.h".
13739 then the ../lib include files in angle brackets (alphabetized),
13740 then the . include files in double-quotes (alphabetized). Fix
13741 dependency breakages encountered in this process, as follows:
13742 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
13743 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
13744 * src/state.h: Include "symtab.h".
13746 2002-12-08 Paul Eggert <eggert@twinsun.com>
13748 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
13749 since this causes problems when __file__ contains character
13750 sequences like "@" that are treated specially by src/scan-skel.l.
13751 Instead, just use the file's basename. This fixes the bug
13752 reported by Martin Mokrejs in
13753 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
13755 2002-12-06 Paul Eggert <eggert@twinsun.com>
13757 Add support for rules that do not have trailing semicolons, as
13758 POSIX requires. Improve the quality of locations in Bison
13761 * src/location.c: Include <quotearg.h>.
13762 (empty_location): Now const.
13763 (location_print): New function. Follow the recommendation of the
13764 GNU Coding Standards for locations that span file boundaries.
13765 * src/location.h: Do not include <quotearg.h>; no longer needed.
13766 (boundary): New type.
13767 (location_t): Use it. This allows locations to span file boundaries.
13768 All member uses changed: file -> start.file or end.file (as needed),
13769 first_line -> start.line, first_column -> start.column,
13770 last_line -> end.line, last_column -> end.column.
13771 (equal_boundaries): New function.
13772 (LOCATION_RESET, LOCATION_STEP): Remove.
13773 (LOCATION_PRINT): Remove. All callers changed to use location_print.
13774 (empty_location): Now const.
13775 (location_print): New decl.
13776 * src/parse-gram.y (lloc_default): New function, which handles
13777 empty locations more accurately.
13778 (YYLLOC_DEFAULT): Use it.
13779 (%token COLON): Remove.
13780 (%token ID_COLON): New token.
13782 (declarations, rules): Remove trailing semicolon.
13783 (declaration, rules_or_grammar_declaration):

13786 (rules_or_grammar_declaration): Remove trailing semicolon.
13787 (semi_colon.opt): Remove.
13788 * src/reader.h: Include location.h.
13789 (scanner_cursor): New decl.
13790 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
13792 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
13794 (STEP): Remove. No longer needed, now that adjust_location does
13795 the work. All uses removed.
13796 (scanner_cursor): New var.
13797 (adjust_location): Renamed from extend_location. It now sets
13798 *loc and adjusts the scanner cursor. All uses changed.
13799 Don't bother testing for CR.
13800 (handle_syncline): Remove location arg; now updates scanner cursor.
13801 All callers changed.
13802 (unexpected_end_of_file): Now accepts start boundary of token or
13803 comment, not location. All callers changed. Update scanner cursor,
13805 (SC_AFTER_IDENTIFIER): New state.
13806 (context_state): Renamed from c_context. All uses changed.
13807 (id_loc, code_start, token_start): New local vars.
13808 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
13809 processing of Yacc white space and equivalents here.
13810 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
13811 instead of returning ID immediately, since we need to search for
13812 a subsequent colon.
13813 (<INITIAL>"'", "\""): Save token_start.
13814 (<INITIAL>"%{", "{", "%%"): Save code_start.
13815 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
13816 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
13817 BEGIN context_state at end, not INITIAL.
13818 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
13819 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
13820 Return correct token start.
13821 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
13822 the start of a character, string or multiline comment is found.
13823 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
13824 Reduction): Adjust reported locations to match the more-precise
13825 results now expected.
13826 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
13827 * tests/reduce.at (Useless Rules, Reduced Automaton,
13828 Underivable Rules): Likewise.
13829 * tests/regression.at (Invalid inputs): No longer `expecting ";"
13830 or "|"' now that so many other tokens are allowed by the new grammar.
13832 * src/complain.h (current_file): Remove duplicate decl;
13833 current_file is now owned by files.h.
13834 * src/complain.c, src/scan-gram.l: Include files.h.
13836 2002-12-06 Paul Eggert <eggert@twinsun.com>
13838 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
13839 promotes to int; it might be unsigned int.
13840 * data/yacc.c (yy_reduce_print): Likewise.
13842 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
13843 be #defined in the prologue, not in the Bison declarations.
13844 This fixes Debian Bug 102878, reported by Shaul Karl.
13846 2002-12-02 Paul Eggert <eggert@twinsun.com>
13848 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
13849 * lib/strtoul.c: New file, from gnulib.
13850 This fixes a porting bug reported by Peter Klein in
13851 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13853 2002-11-30 Paul Eggert <eggert@twinsun.com>
13855 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13856 and put only a forward declaration in the prologue. This is for
13857 consistency with the other scanner helper functions.
13859 Type clashes now generate warnings, not errors, since it
13860 appears that POSIX may allow some grammars with type clashes.
13861 * src/reader.c (grammar_current_rule_check): Warn about
13862 type clashes instead of complaining.
13863 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13865 Add Yacc library, since POSIX requires it.
13866 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13867 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13868 * lib/main.c, lib/yyerror.c: New files.
13870 gram_error can be static; it need not be extern.
13871 * src/reader.h (gram_error): Remove decl.
13872 * src/parse-gram.y (gram_error): Now static. Add static decl.
13873 (print_token_value): Omit parameter names from forward decl,
13876 2002-11-29 Paul Eggert <eggert@twinsun.com>
13878 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13879 be declared before being used. E.g., one should typically
13880 declare them in the prologue. Use GNU coding style in examples.
13881 Put "const" consistently after the type it modifies. Mention
13882 that C99 supports "inline". Mention that yyerror traditionally
13885 %parse-param and %lex-param now take just one argument, the
13886 declaration; the argument name is deduced from the declaration.
13888 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13889 Reporting, Table of Symbols): Document this.
13890 * src/parse-gram.y (add_param): New function.
13892 (declaration): Implement new rule for %parse-param and %lex-param.
13893 * src/scan-gram.l: "," now elicits a warning, rather than being
13894 a token; this is more compatible with byacc.
13895 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13897 2002-11-27 Paul Eggert <eggert@twinsun.com>
13899 Rename identifiers to avoid real and potential collisions.
13901 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13902 to avoid collision with lex macro described by Bruce Lilly in
13903 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13904 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13905 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13906 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13908 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13909 The name "yycontrol" violates the name space rules, and this stuff
13910 wasn't being used anyway.
13911 (input): Remove action; this stuff wasn't being used.
13912 (gram_error): Rename local variable yylloc -> loc.
13913 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13914 (YY_DECL): Don't use "yy" at start of local variables.
13915 All uses changed, e.g., yylloc -> loc.
13916 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
13917 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
13918 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
13919 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
13921 * src/parse-gram.y (gram_error): loc is now const *.
13922 * src/reader.h (gram_error): Likewise.
13924 2002-11-24 Paul Eggert <eggert@twinsun.com>
13928 * tests/actions.at (Actions after errors): Use an output format
13929 more similar to that of the Printers and Destructors test.
13930 Test the position of the ';' token too.
13931 (Printers and Destructors): Likewise.
13932 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13933 unnecessarily alarming people when the test fails.
13935 * data/yacc.c (yyerrlab1): Move this label down, so that the
13936 parser does not discard the lookahead token if the user code
13937 invokes YYERROR. This change is required for POSIX conformance.
13939 * lib/error.c: Sync with gnulib.
13941 2002-11-22 Paul Eggert <eggert@twinsun.com>
13943 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.

13947 2002-11-20 Paul Eggert <eggert@twinsun.com>
13949 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13951 2002-11-20 Paul Eggert <eggert@twinsun.com>
13953 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13954 should use `if (! x) abort ();' rather than `assert (x);', and
13955 anyway it's one less thing to worry about configuring.
13957 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13958 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13959 and replace all instances of assert with abort.
13960 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
13961 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
13963 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
13964 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
13965 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
13966 hash_find_entry, hash_rehash, hash_insert): Likewise.
13967 * src/conflicts.c (resolve_sr_conflict): Likewise.

13973 state_reduction_find): Likewise.
13974 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
13975 symbol_pack): Likewise.
13976 * src/tables.c (conflict_row, pack_vector): Likewise.
13977 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13978 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13979 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
13980 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
13982 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
13983 (ARGMATCH_CONSTRAINT): New macro.
13984 (ARGMATCH_ASSERT): Use it.
13986 * src/system.h (verify): New macro.
13987 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
13988 rather than assert.
13989 * src/tables.c (tables_generate): Likewise.
13991 * src/struniq.c (struniq_assert): Now returns void, and aborts
13992 if the assertion is false.
13993 (struniq_assert_p): Remove.
13994 * src/struniq.h: Likewise.
13996 2002-11-18 Paul Eggert <eggert@twinsun.com>
13998 * data/glr.c (yygetLRActions): Replace `yyindex' with
13999 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
14000 This fixes the regression with Sun ONE Studio 7 cc that I reported in
14001 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
14003 2002-11-18 Akim Demaille <akim@epita.fr>
14005 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
14007 From Tim Van Holder.
14009 2002-11-17 Paul Eggert <eggert@twinsun.com>
14011 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
14012 to "SyntaxError" for consistency with my 2002-11-15 change.
14014 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
14015 not define to {}, since this breaks the common use of `YYDPRINTF
14016 ((...));' if a single statement is desired (e.g. before `else').
14017 Work around GCC warnings by surrounding corresponding calls with
14019 (yyhasResolvedValue): Remove unused function.
14020 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
14022 (yyreportSyntaxError): Renamed from yyreportParseError.
14023 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
14025 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
14026 extern when possible. Remove unused initializations.
14028 2002-11-16 Akim Demaille <akim@epita.fr>
14030 Augment the similarity between GLR and LALR traces.
14032 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
14033 (YY_REDUCE_PRINT): New.
14034 (yyparse): Use them.
14035 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
14037 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
14038 state reached after the reduction/recovery, since...
14039 (yyparse, yyprocessOneStack): Report the state we are entering in.
14041 2002-11-16 Akim Demaille <akim@epita.fr>
14043 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
14044 Add support for --trace=skeleton.
14045 * src/scan-skel.l: %option debug.
14046 Scan strings of non-@ or \n instead of character by character.
14047 (scan_skel): Handle trace_skeleton.
14049 (@output_parser_name@, @output_header_name@): ``Restore'' their
14050 support (used to be M4 macros).
14051 * data/yacc.c: Quote larger chunks, a la glr.c.
14052 * data/lalr1.cc: Likewise.
14053 The header guards are no longer available, so use some other
14054 string than `YYLSP_NEEDED'.
14056 2002-11-16 Akim Demaille <akim@epita.fr>
14058 Make the ``Printers and Destructors'' test more verbose, taking
14059 `yacc.c''s behavior as (possibly wrong) reference.
14061 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
14062 instead of fprint on stdout.
14063 Set and report the last_line of the symbols.
14064 Consistently display values and locations.
14066 2002-11-16 Paul Eggert <eggert@twinsun.com>
14068 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
14070 2002-11-15 Paul Eggert <eggert@twinsun.com>
14072 * tests/actions.at (Actions after errors): New test case.
14074 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
14075 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
14076 tests/action.at, tests/calc.at, tests/conflicts.at,
14077 tests/cxx-type.at, tests/regression.at:
14078 "parse error" -> "syntax error" for POSIX compatibility.
14079 "parsing stack overflow..." -> "parser stack overflow" so
14080 that code matches Bison documentation.
14082 2002-11-15 Akim Demaille <akim@epita.fr>
14084 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
14085 take two BRACED_CODE, not two string_content.
14086 Free the scanner's obstack when we are done.
14087 (code_content): New.
14088 * tests/calc.at: Adjust.
14089 * doc/bison.texinfo: Adjust.
14090 Also, make sure to include the `,' for these declarations.
14092 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
14094 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
14095 definition; avoids potential autoreconf problems.
14097 2002-11-15 Akim Demaille <akim@epita.fr>
14099 Always check the value returned by yyparse.
14101 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
14102 returned by yyparse.
14103 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
14105 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
14106 returned by yyparse.
14108 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14110 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
14113 2002-11-14 Paul Eggert <eggert@twinsun.com>
14115 * src/output.c (output_skeleton): Call xfopen instead of
14116 duplicating xfopen's body.
14118 Fix bugs reported by Nelson H. F. Beebe in
14119 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
14121 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
14122 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
14123 Group compiler. Instead, use "$CC -E bar.c". Include the .h
14124 file twice in the grammar, as an extra check.
14126 * tests/input.at (Torturing the Scanner): Surround the
14127 backslash-newline tests with "#if 0", to make it less likely that
14128 we'll run into compiler bugs. Bring back solitary \ inside
14129 comment, but add a closing comment to work around HP C bug. Don't
14130 test backslash-newline in C character constant.
14132 2002-11-14 Akim Demaille <akim@epita.fr>
14134 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
14135 status of the compiler.
14136 Calling `exit 1' is no longer needed.
14137 Reported by Nelson H. F. Beebe.
14139 2002-11-14 Akim Demaille <akim@epita.fr>
14141 * tests/atlocal.in (CPPFLAGS): We have config.h.
14142 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
14144 * tests/actions.at, tests/calc.at, tests/conflicts.at,
14145 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
14146 * tests/regression.at, tests/torture.at: Use them for all the
14147 grammars that are to be compiled.
14148 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
14149 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
14150 * doc/bison.texinfo (GLR Parsers): Document `inline'.
14152 2002-11-14 Akim Demaille <akim@epita.fr>
14154 * doc/bison.texinfo: Various formatting changes (alignments in
14155 samples, additional @group/@end group, GCS in samples.
14156 Use @deffn instead of simple @table to define the directives,
14157 macros, variables etc.
14159 2002-11-13 Paul Eggert <eggert@twinsun.com>
14161 Fix some bugs reported by Albert Chin-A-Young in
14162 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
14164 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
14165 -o c"; the HP C compiler chatters during compilation.
14166 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
14167 * tests/headers.at (export YYLTYPE): Likewise.
14169 * tests/input.at (Torturing the Scanner): Remove lines containing
14170 solitary backslashes, as they tickle a bug in the HP C compiler.
14172 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
14173 comments, since they're not portable. Use GNU coding style.
14175 2002-11-13 Akim Demaille <akim@epita.fr>
14177 * data/yacc.c: Leave bigger chunks of quoted text.
14178 (YYDSYMPRINTF): New.
14179 Use it to report symbol activities.
14180 * data/glr.c (YYDSYMPRINTF): New.
14183 2002-11-12 Paul Eggert <eggert@twinsun.com>
14187 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
14188 (yyglrReduce): Return yyok, not 0.
14189 This should avoid the enumerated-type warnings reported
14190 by Nelson H. F. Beebe in
14191 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
14193 * lib/bbitset.h (BITSET_INLINE): Remove.
14194 * lib/bitset.h [! BITSET_INLINE]: Remove.
14195 (bitset_set, bitset_reset, bitset_test): Rename local vars
14196 to avoid shadowing warnings by GCC.
14198 * data/glr.c (inline): Remove #define. It's the user's
14199 responsibility to #define it away, just like 'const'.
14200 This fixes one of the bugs reported by Nelson H. F. Beebe in
14201 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
14203 * Makefile.maint (po-check): Scan .l and .y files instead of the
14204 .c and the .h files that they generate. This fixes the bug
14205 reported by Tim Van Holder in:
14206 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
14207 Look for N_ as well as for _. Try to avoid matching #define for
14209 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
14210 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
14211 * src/scan-gram.l: Revamp regular expressions so that " and '
14212 do not confuse xgettext.
14214 * src/struniq.h (struniq_new): Do not declare the return type
14215 to be 'const'; this violates the C standard.
14216 * src/struniq.c (struniq_new): Likewise.
14218 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
14220 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
14221 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
14224 2002-11-12 Akim Demaille <akim@epita.fr>
14226 * Makefile.maint: Sync with Autoconf:
14227 (local_updates): New.
14229 2002-11-12 Akim Demaille <akim@epita.fr>
14231 * po/POTFILES.in (src/lalr.c, src/state.c): Remove

14243 2002-11-12 Akim Demaille <akim@epita.fr>
14245 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
14246 Use it to test the GLR parser.
14248 2002-11-12 Akim Demaille <akim@epita.fr>
14250 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
14252 * data/glr.c (yystos): New.
14253 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
14254 (YYDSYMPRINT): New.
14255 (yyval): Don't define it, it is handled via M4.
14256 (yyrecoverParseError): Free verbosely the discarded symbols.
14257 * data/yacc.c (yysymprint): Remove, rather...
14258 (b4_yysymprint_generate): invoke.
14259 * data/c.m4 (b4_yysymprint_generate): New.
14260 Accept pointers as arguments, as opposed to the version from
14262 (b4_yydestruct_generate): Likewise.
14263 * tests/cations.at (Printers and Destructors): Use Bison directives
14264 instead of CPP macros.
14265 Don't rely on internal details.
14267 2002-11-12 Akim Demaille <akim@epita.fr>
14269 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
14270 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
14271 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
14272 it against YYEMPTY and so forth), work on yytoken (i.e., set
14273 it to YYEMPTY etc.).
14274 (yydestruct): Replace with a b4_yydestruct_generate invocation.
14275 (b4_symbol_actions): Remove.
14276 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
14277 for 0, end-of-input.
14279 2002-11-12 Akim Demaille <akim@epita.fr>
14281 * doc/bison.texinfo (Destructor Decl): New.
14283 2002-11-12 Akim Demaille <akim@epita.fr>
14285 * src/tables.c (tables_generate): Use free for pointers that
14286 cannot be NULL, not XFREE.
14287 (pack_vector): Use assert, not fatal, for bound violations.
14288 * src/state.c (state_new): Likewise.
14289 * src/reader.c (reader): Likewise.
14290 * src/lalr.c (set_goto_map): Likewise.
14291 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
14294 2002-11-12 Akim Demaille <akim@epita.fr>
14296 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
14298 * src/scan-gram.l (last_string): Is global to the file, not to

14301 (epilogue.opt): do it here, and free the scanner's obstack.
14302 * src/reader.c (epilogue_set): Rename as...
14303 (epilogue_augment): this.
14304 * data/c.m4 (b4_epilogue): Defaults to empty.

14347 Don't free the input file name.
14349 2002-11-12 Akim Demaille <akim@epita.fr>
14351 * src/symtab.c (symbol_free): Remove dead deactivated code:

14362 2002-11-11 Paul Eggert <eggert@twinsun.com>
14364 Revamp to fix many (but not all) of the C- and M4-related quoting
14365 problems. Among other things, this fixes the Bison bug reported
14366 by Jan Hubicka when processing the Bash grammar; see:
14367 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
14369 Use new @ escapes consistently. Represent brackets with @{ and @}
14370 rather than @<:@ and @:>@, since this works a bit better with dumb
14371 editors like vi. Represent @ with @@, since @ is now consistently
14372 an escape. Use @oline@ and @ofile@ rather than __oline__ and
14373 __ofile__, to avoid unexpected expansions. Similarly, use @output
14374 rather than #output.
14376 * data/c.m4 (b4_copyright): Omit file name from comment, since
14377 the file name could contain "*/".
14378 (b4_synclines_flag): Don't quote the 2nd argument; it should already
14379 be quoted. All uses changed.
14381 * data/glr.c: Use new @ escapes consistently.
14382 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
14383 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
14384 Remove, since they couldn't handle arbitrary characters in file
14386 * data/lalr1.cc: Likewise.
14387 * data/yacc.c: Likewise.
14389 * src/files.c (output_infix): Remove; all uses removed.
14390 * src/files.h: Likewise.
14392 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
14393 mishandled funny characters in file names, and anyway it isn't
14395 * data/yacc.c: Likewise.
14396 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
14398 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
14399 * data/yacc.c: Likewise.
14401 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
14403 (muscle_init): Quote filename as a C string.
14404 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
14405 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
14406 * src/output.c (escaped_file_name_output): New function.
14407 (prepare_symbols): Quote tokens for M4.
14408 (prepare): Don't insert output_infix, output_prefix,
14409 output_parser_name, output_header_name; this is now down by scan-skel.
14410 Insert skeleton as a C string.
14412 * src/output.c (user_actions_output, symbol_destructors_output,
14413 symbol_printers_output): Quote filenames for C and M4.
14414 * src/reader.c (prologue_augment, epilogue_set): Likewise.
14416 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
14417 escapes other than \\ and \'; this simplifies the code.
14418 (<SC_STRING>): Likewise, for \\ and \".
14419 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
14420 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
14421 Use new escapes @{ and @} for [ and ].
14423 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
14424 them with auto vars.
14425 Switch to new escape scheme, where @ is the escape character uniformly.
14426 Abort if a stray escape character is found. Avoid unbounded input
14427 buffer when parsing non-escaped text.
14429 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
14430 __oline__, #output, $@, and @{ do not have unintended meanings.
14432 2002-11-09 Paul Eggert <eggert@twinsun.com>
14434 Fix the test failure due to GCC warnings described in
14435 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
14436 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
14437 evaluate to 0 if it's impossible for NINF to be in the respective
14439 (yygetLRActions, yyrecoverParseError): Use them.
14441 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
14442 counted in the token inserted at end of file. Now takes
14443 location_t *, not location_t, so that the location can be
14444 adjusted. All uses changed.
14446 * tests/regression.at (Invalid inputs): Adjust wording in
14447 diagnostic to match the new behavior.
14449 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
14450 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
14451 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
14452 abort ();'. This reduces the runtime of the "Many lookaheads"
14453 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
14456 2002-11-07 Paul Eggert <eggert@twinsun.com>
14458 * src/parse-gram.y (CHARACTER): Remove unused token.
14461 * src/scan-gram.l: Remove stack option. We no longer use the
14462 stack, since the stack was never deeper than 1; instead, use the
14463 new auto var c_context to record the stacked value.
14465 Remove nounput option. At an unexpected end of file, we now unput
14466 the minimal input necessary to end cleanly; this simplifies the
14469 Avoid unbounded token sizes where this is easy.
14471 (unexpected_end_of_file): New function.
14472 Use it to systematize the error message on unexpected EOF.
14473 (last-string): Now auto, not static.
14474 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
14475 (scanner_last_string_free): Remove; not used.
14476 (percent_percent_count): Move decl to just before use.
14477 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
14478 not the (never otherwised-used) CHARACTER.
14480 2002-11-07 Akim Demaille <akim@epita.fr>
14482 Let yyerror always receive the msg as last argument, so that
14483 yyerror can be variadic.
14485 * data/yacc.c (b4_yyerror_args): New.
14486 Use it when calling yyerror.
14487 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

14493 2002-11-06 Akim Demaille <akim@epita.fr>
14495 #line should have quoted strings.
14496 Ideally, this should be done by m4_quotearg.
14498 * src/scan-skel.l: Include quotearg.h.
14500 * src/output.c (symbol_printers_output)
14501 (symbol_destructors_output): Quote the file name.

14516 * src/output.c (user_actions_output): Likewise.
14517 (prepare): Define 'b4_synclines_flag'.
14518 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
14520 2002-11-06 Akim Demaille <akim@epita.fr>

14523 * src/scan-gram.l (handle_syncline): New.
14525 * src/output.c (user_actions_output, symbol_destructors_output)
14526 (symbol_printers_output): Use the location's file name, not

14530 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14532 * src/tables.c (matching_state): Don't allow states to match if
14533 either has GLR conflict entries.
14535 2002-11-05 Paul Eggert <eggert@twinsun.com>
14537 * src/scan-gram.l: Use more accurate diagnostics, e.g.
14538 "integer out of range" rather than "invalid value".
14539 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
14542 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
14543 Also, remove one static variable in the scanner.
14545 * src/scan-gram.l (braces_level): Now auto, not static.
14546 Initialize to zero if the compiler is being picky.
14547 (INITIAL): Clear braces_level instead of incrementing it.
14548 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
14549 as POSIX 1003.1-2001 requires.
14550 * src/system.h (IF_LINT): New macro, taken from coreutils.
14551 * configure.ac: Define "lint" if --enable-gcc-warnings.
14553 2002-11-05 Akim Demaille <akim@epita.fr>
14555 * src/scan-gram.l: When it starts with `%', complain about the
14556 whole directive, not just that `invalid character: %'.
14558 2002-11-04 Akim Demaille <akim@epita.fr>
14560 * Makefile.maint: Update from Autoconf.
14561 (update, cvs-update, po-update, do-po-update): New.
14563 2002-11-04 Akim Demaille <akim@epita.fr>
14565 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
14567 Have yyerror `use' its arguments.
14568 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF

14570 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
14572 2002-11-04 Akim Demaille <akim@epita.fr>
14574 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
14576 * src/scan-gram.l: Use [\'] instead of ['] to pacify
14579 Use quote, not quote_n since LOCATION_PRINT no longer uses the
14582 2002-11-03 Paul Eggert <eggert@twinsun.com>
14584 * src/reader.c (get_merge_function, grammar_current_rule_check):
14585 Use consistent diagnostics for reporting type name clashes.
14586 Quote the types with <>, for consistency with Yacc.
14587 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
14589 2002-11-03 Akim Demaille <akim@epita.fr>
14591 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
14593 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
14594 (b4_parse_param): Remove.
14595 Use b4_identification.
14596 Propagate b4_pure_args where needed to pass them to yyerror.
14597 * data/glr.m4 (b4_parse_param): Remove.
14598 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

14601 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
14602 b4_user_formals and b4_user_args.
14603 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
14604 (yyreportAmbiguity): When using a pure parser, also need
14605 the location, and the parse-params.
14607 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
14608 When using a pure parser, also need the parse-params.
14610 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
14611 (%pure-parser + %parse-param) LALR and GLR parsers.
14612 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
14613 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
14614 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
14615 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
14616 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
14617 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
14618 * doc/bison.texinfo: Untabify the whole file.
14619 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
14620 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
14621 (Error Reporting): Adjust to these new directives.
14622 Document %error-verbose, deprecate YYERROR_VERBOSE.
14624 2002-11-03 Akim Demaille <akim@epita.fr>
14626 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
14627 AT_CHECK_CALC_GLR invocations to use % directives, instead of
14628 command line options.
14629 * tests/cxx-type.at: Formatting changes.
14631 2002-11-03 Paul Eggert <eggert@twinsun.com>
14633 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
14634 to count columns correctly, and to check for invalid inputs.
14636 Use mbsnwidth to count columns correctly. Account for tabs, too.
14637 Include mbswidth.h.
14638 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
14639 (extend_location): New function.
14640 (YY_LINES): Remove.
14642 Handle CRLF in C code rather than in Lex code.
14643 (YY_INPUT): New macro.
14644 (no_cr_read): New function.
14646 Scan UCNs, even though we don't fully handle them yet.

14649 Handle backslash-newline correctly in C code.
14650 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
14651 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
14653 (tag, splice): New EREs. Do not allow NUL or newline in tags.
14654 Use {splice} wherever C allows backslash-newline.
14655 YY_STEP after space, newline, vertical-tab.
14656 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
14658 (letter, id): Don't assume ASCII; e.g., spell out a-z.
14660 ({int}, handle_action_dollar, handle_action_at): Check for integer
14663 (YY_STEP): Omit trailing semicolon, so that it's more like C.
14665 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
14666 as well as \000. Check for UCHAR_MAX, not 255.
14667 Allow \x with an arbitrary positive number of digits, as in C.
14668 Check for overflow here.
14669 Allow \? and UCNs, for compatibility with C.
14671 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
14672 with quote slot used by complain_at.
14674 * tests/input.at: Add tests for backslash-newline, m4 quotes
14675 in symbols, long literals, and funny escapes in strings.
14677 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
14678 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
14679 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
14680 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
14681 * m4/mbswidth.m4: New file, from GNU coreutils.
14683 * doc/bison.texinfo (Grammar Outline): Document // comments.
14684 (Symbols): Document that trigraphs have no special meaning in Bison,
14685 nor is backslash-newline allowed.
14686 (Actions): Document that trigraphs have no special meaning.
14688 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
14691 2002-11-02 Paul Eggert <eggert@twinsun.com>
14693 * src/reader.c: Don't include quote.h; not needed.
14694 (get_merge_function): Reword warning to be consistent with
14695 type clash diagnostic in grammar_current_rule_check.
14697 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
14698 bug in trigraph handling.
14700 * src/output.c (prepare_symbols): When printing token names,
14701 escape "[" as "@<:@" and likewise for "]".
14703 * src/system.h (errno): Remove declaration, as we are now
14704 assuming C89 or better, and C89 guarantees errno.
14706 2002-10-30 Paul Eggert <eggert@twinsun.com>
14708 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
14709 Check for close failures.
14710 * src/files.h (xfclose): Return void, not int, since it always
14712 * src/files.c (xfclose): Likewise. Report I/O error if ferror
14714 * src/output.c (output_skeleton): Use xfclose rather than fclose
14715 and ferror. xfclose now checks ferror.
14717 * data/glr.c (YYLEFTMOST_STATE): Remove.
14718 (yyreportTree): Use a stack-based leftmost state. This avoids
14719 our continuing battles with bogus warnings about initializers.
14721 2002-10-30 Akim Demaille <akim@epita.fr>
14723 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
14726 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14728 * tests/glr-regr1.at: New test for reported regressions.
14729 * tests/testsuite.at: Add glr-regr1.at test.
14730 * tests/Makefile.am: Add glr-regr1.at test.
14732 2002-10-24 Paul Eggert <eggert@twinsun.com>
14736 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
14737 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
14738 we use malloc. Don't assume 'A' through 'Z' are contiguous.
14739 Don't assume strdup exists; POSIX says its an XSI extension.
14740 Check for buffer overflow on input.
14742 2002-10-24 Akim Demaille <akim@epita.fr>
14744 * src/output.c (output_skeleton): Don't disable M4sugar comments
14745 too soon: it results in comments being expanded.
14746 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
14749 2002-10-24 Akim Demaille <akim@epita.fr>
14751 * data/yacc.c (m4_int_type): New.
14752 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
14753 char' as only yacc.c wants K&R portability.
14754 * data/glr.c (yysigned_char): Remove.
14755 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
14756 Reported by Quoc Peyrot.
14758 2002-10-23 Paul Eggert <eggert@twinsun.com>
14760 * src/main.c (main): With --trace=time, report times even if a
14761 non-fatal error occurs. Formerly, the times were reported in some
14762 such cases but not in others.
14763 * src/reader.c (reader): Just return if a complaint has been issued,
14764 instead of exiting, so that 'main' can report times.
14766 2002-10-22 Akim Demaille <akim@epita.fr>
14768 * src/system.h: Include sys/types.
14769 Reported by Bert Deknuydt.
14771 2002-10-23 Paul Eggert <eggert@twinsun.com>
14773 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
14774 Suggested by Art Haas.
14776 2002-10-22 Paul Eggert <eggert@twinsun.com>
14778 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14779 decl; not needed any more.
14780 * src/main.c (main): Use return to exit, undoing yesterday's change.
14781 The last OS that we could find where this wouldn't work is
14782 SunOS 3.5, and that's too old to worry about now.
14784 * data/glr.c (struct yyltype): Define members even when not
14785 doing locations. This is more consistent with yacc.c, and it
14786 works around the following bug reports:
14787 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
14788 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
14790 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
14791 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14792 "Algol" instead of "ALGOL". Give a bit more history about BNF.
14794 2002-10-22 Akim Demaille <akim@epita.fr>
14796 * data/README: New.
14798 2002-10-21 Paul Eggert <eggert@twinsun.com>
14800 Be consistent about 'bool'; the old code used an enum in one
14801 module and an int in another, and this violates the C standard.
14802 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14803 * configure.ac (AC_HEADER_STDBOOL): Add.
14804 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14805 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14806 * src/symtab.c (hash_compare_symbol_t): Likewise.
14807 * src/system.h (bool, false, true): Use a definition consistent
14808 with ../lib/hash.c. All uses changed.
14810 * src/complain.c (warning_issued): Renamed from warn_message_count,
14811 so that we needn't worry about integer overflow (!).
14812 Now of type bool. All uses changed.
14813 (complaint_issued): Renamed from complain_message_count; likewise.
14815 * src/main.c (main): Use exit to exit with failure.
14817 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
14818 rather than 1 and 0.
14819 * src/main.c (main): Likewise.
14820 * src/getargs.c (getargs): Likewise.
14821 * src/reader.c (reader): Likewise.
14823 * src/getarg.c (getargs): Remove duplicate code for
14824 "Try `bison --help'".
14826 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
14827 What was that "2" for?
14829 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14830 * src/getargs.c (usage): Likewise.
14832 * src/getargs.c (getargs): When there are too few operands, report
14833 the last one. When there are too many, report the first extra
14834 one. This is how diffutils does it.
14836 2002-10-20 Paul Eggert <eggert@twinsun.com>
14838 Remove K&R vestiges.
14839 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
14840 * src/complain.c (VA_START): Remove. Assume prototypes.
14841 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
14842 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
14843 fatal): Assume prototypes.
14844 * src/complain.h: Assume prototypes.
14845 * src/system.h (PARAMS): Remove.
14846 Include <limits.h> unconditionally, since it's guaranteeed even
14847 for a freestanding C89 compiler.
14848 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
14849 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
14851 2002-10-20 Akim Demaille <akim@epita.fr>

14856 (yyresolveStates, yyresolveAction, yyresolveStack)
14857 (yyprocessOneStack): Use them.
14858 (yy_reduce_print): New.
14859 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
14861 2002-10-20 Akim Demaille <akim@epita.fr>
14863 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14864 arguments and output `void'.
14865 (b4_c_function): Rename as...
14866 (b4_c_function_def): this.
14867 (b4_c_function_decl, b4_c_ansi_function_def)
14868 (b4_c_ansi_function_decl): New.
14869 Change the interpretation of the arguments: before `int, foo', now
14871 * data/yacc.c (yyparse): Prototype and define thanks to these.
14872 Adjust b4_c_function_def uses.
14873 * data/glr.c (yyparse): Likewise, but ANSI only.
14875 2002-10-20 Akim Demaille <akim@epita.fr>
14877 * src/output.c (prepare): Move the definition of `tokens_number',
14878 `nterms_number', `undef_token_number', `user_token_number_max'
14880 (prepare_tokens): Here.
14881 (prepare_tokens): Rename as...
14882 (prepare_symbols): this.
14883 (prepare): Move the definition of `rules_number' to...
14884 (prepare_rules): here.
14885 (prepare): Move the definition of `last', `final_state_number',
14886 `states_number' to...
14887 (prepare_states): here.
14888 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
14890 2002-10-20 Akim Demaille <akim@epita.fr>
14892 * src/tables.h, src/tables.c, src/output.c: Comment changes.
14894 2002-10-20 Akim Demaille <akim@epita.fr>
14896 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
14899 2002-10-20 Akim Demaille <akim@epita.fr>

14907 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
14910 2002-10-19 Paul Eggert <eggert@twinsun.com>
14912 Do not create a temporary file, as that involves security and
14913 cleanup headaches. Instead, use a pair of pipes.
14914 Derived from a suggestion by Florian Krohm.
14915 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14916 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
14917 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
14918 (BISON_PREREQ_SUBPIPE): Add.
14919 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
14920 Add subpipe.h, subpipe.c.

14924 (m4_invoke): Remove decl.
14925 (scan_skel): New decl.
14926 (output_skeleton): Use pipe rather than temporary file for m4 input.
14927 Check that m4sugar.m4 is readable, to avoid deadlock.
14928 Check for pipe I/O error.
14929 * src/scan-skel.l (readpipe): Remove decl.
14930 (scan_skel): New function, to be used in place of m4_invoke.
14931 Read from stream rather than file.
14933 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14934 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14935 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14936 this generates a more-accurate value anyway.
14938 * lib/timevar.c (timervar_accumulate): Rename locals to
14939 avoid confusion with similarly-named more-global.
14940 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14942 * src/output.c (prepare): Use xstrdup to convert char const *
14943 to char *, to avoid GCC warning.
14945 2002-10-19 Akim Demaille <akim@epita.fr>
14947 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14948 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14949 Use them to have `calc.y' ready for %pure-parser.
14950 * data/yacc.c (YYLEX): Pass a yylex return type to
14951 b4_c_function_call.
14953 2002-10-19 Akim Demaille <akim@epita.fr>
14955 Prototype support of %lex-param and %parse-param.
14957 * src/parse-gram.y: Add the definition of the %lex-param and
14958 %parse-param tokens, plus their rules.
14959 Drop the `_' version of %glr-parser.
14961 * src/scan-gram.l (INITIAL): Scan them.
14962 * src/muscle_tab.c: Comment changes.
14963 (muscle_insert, muscle_find): Rename `pair' as `probe'.
14964 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
14965 (muscle_entry_s): The `value' member is no longer const.
14966 Adjust all dependencies.
14967 * src/muscle_tab.c (muscle_init): Adjust: use
14968 MUSCLE_INSERT_STRING.
14969 Initialize the obstack earlier.
14970 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14971 (muscle_pair_list_grow): New.
14972 * data/c.m4 (b4_c_function_call, b4_c_args): New.
14973 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
14974 * tests/calc.at: Use %locations, not --locations.
14975 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14977 2002-10-19 Akim Demaille <akim@epita.fr>
14979 * src/getargs.c (usage): Take status as argument and exit
14981 Report the traditional `Try ... --help' message when status != 0.
14982 (usage, version): Don't take a FILE * as arg, it is pointless.
14983 (getargs): When there is an incorrect number of arguments, make it
14984 an error, and report it GNUlically thanks to `usage ()'.
14986 2002-10-18 Paul Eggert <eggert@twinsun.com>
14988 * data/glr.c (yyreportParseError): Don't assume that sprintf
14989 yields the length of the printed string, as this is not true
14990 on SunOS 4.1.4. Reported by Peter Klein.
14992 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14993 * tests/conflicts.at (%nonassoc and eof): Likewise.
14994 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14996 2002-10-17 Akim Demaille <akim@epita.fr>
14998 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14999 * src/getargs.c (trace_types, trace_args): Adjust.
15000 * src/reader.c (grammar_current_rule_prec_set)
15001 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
15002 Standardize error messages.
15003 And s/@prec/%prec/!
15004 (reader): Use trace_flag to enable scanner/parser debugging,
15005 instead of an adhoc scheme.
15006 * src/scan-gram.l: Remove trailing debugging code.
15008 2002-10-16 Paul Eggert <eggert@twinsun.com>
15010 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
15013 * NEWS: Officially drop support for building Bison with K&R C,
15014 since it didn't work anyway and it's not worth worrying about.
15015 * Makefile.maint (wget_files): Remove ansi2knr.c.
15016 (ansi2knr.c-url_prefix): Remove.
15017 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
15018 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15019 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15021 2002-10-15 Paul Eggert <eggert@twinsun.com>
15023 Stop using the "enum_" trick for K&R-style function definitions;
15024 it confused me, and I was the author! Instead, assume that people
15025 who want to use K&R C compilers (when using these modules in GCC,
15026 perhaps?) will run ansi2knr.
15028 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
15029 All uses of "enum_" changed to "enum ".
15030 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15031 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15033 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

15040 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
15041 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
15042 Use function prototypes; this removes the need for declaring
15043 static functions simply to provide their prototypes.
15044 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

15071 bitsetv_zero, bitsetv_ones, bitsetv_transitive_closure,

15101 2002-10-14 Akim Demaille <akim@epita.fr>
15103 * tests/Makefile.am (maintainer-check-posix): New.
15105 2002-10-14 Akim Demaille <akim@epita.fr>
15107 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
15110 2002-10-14 Akim Demaille <akim@epita.fr>
15112 * src/tables.c (table_ninf_remap): base -> tab.
15113 Reported by Matt Rosing.
15115 2002-10-14 Paul Eggert <eggert@twinsun.com>
15117 * tests/action.at, tests/calc.at, tests/conflicts.at,
15118 tests/cxx-type.at, tests/headers.at, tests/input.at,
15119 tests/regression.at, tests/synclines.at, tests/torture.at:
15120 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
15121 so that the tests still work even if POSIXLY_CORRECT is set.
15122 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
15124 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
15125 for portability to K&R hosts. Fix typo: signed char is guaranteed
15126 only to 127, not to 128.
15127 * data/glr.c (yysigned_char): New type.
15128 * data/yacc.c (yysigned_char): Likewise.
15129 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
15131 2002-10-13 Paul Eggert <eggert@twinsun.com>
15133 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
15134 true due to limited range of data type" warning from GCC.
15136 * data/c.m4 (b4_token_defines): Protect against double-inclusion
15137 by wrapping enum yytokentype's definition inside #ifndef
15138 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
15140 2002-10-13 Akim Demaille <akim@epita.fr>
15142 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
15143 Un yy- yyrhs to avoid the name clash with the global YYRHS.
15145 2002-10-13 Akim Demaille <akim@epita.fr>
15147 * Makefile.maint: Update from Autoconf 2.54.
15148 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
15150 2002-10-13 Akim Demaille <akim@epita.fr>
15152 * src/print.c (print_state): Separate the list of solved conflicts
15153 from the other items.
15154 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
15156 2002-10-13 Akim Demaille <akim@epita.fr>
15158 Let nondeterministic skeletons be usable with deterministic
15161 With the patch, GAWK compiled by GCC without -O2 passes its test
15162 suite using a GLR parser driven by LALR tables. It fails with -O2
15163 because `struct stat' gives two different answers on my machine:
15164 88 (definition of an auto var) and later 96 (memset on this var).
15165 Hence the stack is badly corrumpted. The headers inclusion is to
15166 blame: if I move the awk.h inclusion before GLR's system header
15167 inclusion, the two struct stat have the same size.
15169 * src/tables.c (pack_table): Always create conflict_table.
15170 (token_actions): Always create conflict_list.
15171 * data/glr.c (YYFLAG): Remove, unused.
15173 2002-10-13 Akim Demaille <akim@epita.fr>
15175 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
15177 (VALGRIND, GXX): New.
15178 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
15179 * tests/bison.in: Run $PREBISON a pre-command.
15180 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
15181 (maintainer-check-g++): New.
15182 * Makefile.am (maintainer-check): New.
15184 2002-10-13 Akim Demaille <akim@epita.fr>
15186 * data/glr.c: Formatting changes.
15187 Tweak some trace messages to match yacc.c's.
15189 2002-10-13 Akim Demaille <akim@epita.fr>
15191 GLR parsers sometimes raise parse errors instead of performing the
15193 Reported by Charles-Henry de Boysson.
15195 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
15196 check the length of the traces when %glr.
15197 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
15199 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
15201 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
15202 (yyltype): Remove the yy prefix from the member names.
15203 (yytable): Complete its comment.
15204 (yygetLRActions): Map error action number from YYTABLE from
15206 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
15207 (which was a bug: it should have been YYTABEL_NINF, and yet it was
15208 not satisfying as we could compare an YYACTION computed from
15209 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
15210 only value for error actions.
15211 (yyreportParseError): In verbose parse error messages, don't issue
15212 `error' in the list of expected tokens.
15213 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
15214 next action to perform to match glr.c's decoding.
15215 (yytable): Complete its comment.
15217 2002-10-13 Paul Eggert <eggert@twinsun.com>
15219 Fix problem reported by Henrik Grubbstroem in
15220 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
15221 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
15222 because the Bison parser reads the second action before reducing
15224 * src/scan-gram.l (rule_length): New static var.
15225 Use it to keep track of the rule length in the scanner, since
15226 we can't expect the parser to be in lock-step sync with the scanner.
15227 (handle_action_dollar, handle_action_at): Use this var.
15228 * tests/actions.at (Exotic Dollars): Test for the problem.
15230 2002-10-12 Paul Eggert <eggert@twinsun.com>
15232 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
15233 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
15234 Include <sys/time.h> when checking for clock_t and struct tms.
15235 Use same include order as source.
15236 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
15237 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
15239 * lib/timevar.c: Update copyright date and clarify comments.
15240 (get_time) [IN_GCC]: Keep the GCC version for reference.
15242 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
15243 GCC version as of today, then merge Bison's changes.
15244 Change "GCC" to "Bison" in copyright notice. timevar.def's
15245 author is Akim, so change that too.
15247 * src/reader.c (grammar_current_rule_check):
15248 Don't worry about the default action if $$ is untyped.
15249 Prevents bogus warnings reported by Jim Gifford in

15260 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
15261 (yyparse): here. This undoes some of the 2002-07-25 change.

15278 Portability fixes for bitsets; this also avoids several GCC
15281 * lib/abitset.c: Include <stddef.h>, for offsetof.
15282 * lib/lbitset.c: Likewise.
15284 * lib/abitset.c (abitset_bytes): Return a size that is aligned
15285 properly for vectors of objects. Do not assume that adding a
15286 header size to a multiple of a word size yields a value that is
15287 properly aligned for the whole union.
15288 * lib/bitsetv.c (bitsetv_alloc): Likewise.
15290 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
15291 unique names for structures.
15292 * lib/ebitset.c (ebitset_bytes): Likewise.
15293 * lib/lbitset.c (lbitset_bytes): Likewise.
15295 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
15296 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,

15300 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
15301 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
15302 to improve the type-checking that GCC can do.
15303 * lib/bitset.c (bitset_op4_cmp): Likewise.
15304 * lib/bitset_stats.c (bitset_stats_count,
15305 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

15321 * lib/lbitset.h: Likewise.
15323 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
15324 All instances of parameters of type enum bitset_opts are now of
15325 type enum_bitset_opts, to conform to the C Standard, and similarly
15326 for enum_bitset_type.
15327 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15328 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15330 Do not use "struct bitset_struct" to mean different things in
15331 different modules. Not only is this confusing, it violates
15332 the C Standard, which requires that structure types in different
15333 modules must be compatible if one is to be passed to the other.
15334 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
15335 All instances of "struct bitset_struct *" replaced with "bitset".
15336 * lib/bitset.h (struct bitset_struct): Remove, replacing with....

15345 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
15346 bitset_struct): Remove.
15347 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
15350 Do not call a function of type T using a call that assumes the
15351 function is of a different type U. Standard C requires that a
15352 function must be called with a type that is compatible with its
15354 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
15356 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
15358 * lib/ebitset.c (PFV): Remove.
15359 * lib/lbitset.c (PFV): Likewise.

15369 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
15372 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
15374 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
15375 Use offsetof, for simplicity.
15377 2002-10-06 Paul Eggert <eggert@twinsun.com>
15379 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
15380 the same width as int. This reapplies a hunk of the 2002-08-12 patch
15381 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
15382 which was inadvertently undone by the 2002-09-30 patch.
15383 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
15384 the same width as int.
15386 2002-10-04 Paul Eggert <eggert@twinsun.com>
15390 * configure.ac (AC_INIT), NEWS: Increment version number.
15392 * doc/bison.texinfo: Minor spelling, grammar, and white space
15394 (Symbols): Mention that any negative value returned from yylex
15395 signifies end-of-input. Warn about negative chars. Mention
15396 the portable Standard C character set.

15399 for the installer to set.
15400 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
15401 * src/Makefile.am (AM_CFLAGS): Likewise.

15408 * src/reader.c (reader): Use it.
15410 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
15411 POSIX 1003.1-2001 has removed fgrep.
15413 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

15692 (bitset_test): Now returns int, not unsigned long.
15694 * lib/bitset_stats.c: Include "gettext.h".
15696 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
15697 name locals "index", as it generates unnecessary warnings on some
15698 hosts that have an "index" function.

15701 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

15736 to void, to avoid a GCC warning when --disable-nls is in effect.
15738 * src/scan-gram.l: Use strings rather than escapes when possible,
15739 to minimize the number of warnings from xgettext.
15740 (handle_action_dollar, handle_action_at): Don't use isdigit,
15741 as it mishandles negative chars and it may not work as expected
15742 outside the C locale.
15744 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
15745 this is a GCC extension and is not portable to other compilers.

15752 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
15755 * tests/regression.at: Do not use 'cc -c input.c -o input';
15756 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
15758 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
15759 exit status as failure, not just exit status 1. Sun C exits
15760 with status 2 sometimes.
15762 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
15763 Use it for the two large tests.

15929 Note: the final state is now a ``regular'' state, i.e., the
15930 parsers now contain `reduce 0' as default reduction.
15931 Nevertheless, since they decide to `accept' when yystate =
15932 final_state, they still will not reduce rule 0.

15978 yycontrol without making too strong assumptions on the parser

15981 token_translations instead of `0'.
15982 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
15984 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
15985 for the time being: %locations ought to provide it to yyerror.
15987 2002-07-25 Akim Demaille <akim@epita.fr>
15989 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

16004 Handle the `- 1' part in rule numbers from/to item numbers.

17634 * data/bison.c++ (r1_): Likewise.
17635 * tests/regression.at (Web2c Actions): Adjust.
17637 2002-04-22 Akim Demaille <akim@epita.fr>
17639 * src/reader.c (token_translations_init): 256 is now the default
17640 value for the error token, i.e., it will be assigned another
17641 number if the user assigned 256 to one of her tokens.
17642 (reader): Don't force 256 to error.
17643 * doc/bison.texinfo (Symbols): Adjust.
17644 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
17645 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
17646 etc. instead of 10, 20, 30 (which was used to `jump' over error
17647 (256) and undefined (2)).
17649 2002-04-22 Akim Demaille <akim@epita.fr>

17686 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
17687 full stderr, and strip it according to the bison options, instead
17688 of composing the error message from different bits.
17689 This makes it easier to check for several error messages.
17690 Adjust all the invocations.
17691 Add an invocation exercising the error token.
17692 Add an invocation demonstrating a stupid error message.
17693 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

17711 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
17712 `user_token_number_max'.

17753 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
17754 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
17755 passes, but produces negative #line number, once fixed, GCC is

17956 2002-04-07 Akim Demaille <akim@epita.fr>
17958 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
17959 lacking `+ 1' to nrules, Bison reported as useless a token if it
17960 was used solely to set the precedence of the last rule...
17962 2002-04-07 Akim Demaille <akim@epita.fr>
17964 * data/bison.c++, data/bison.simple: Don't output the current file
17965 name in #line, to avoid useless diffs between two identical
17966 outputs under different names.
17968 2002-04-07 Akim Demaille <akim@epita.fr>
17970 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

17985 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
17986 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
17987 RHS, instead of being an index in RITEMS.
17989 2002-04-04 Paul Eggert <eggert@twinsun.com>
17991 * doc/bison.texinfo: Update copyright date.
17992 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

18218 notice in each output file.
18220 2002-02-28 Akim Demaille <akim@epita.fr>
18222 * data/bison.c++: Copy the prologue of bison.simple to fetch
18223 useful M4 definitions, such as b4_header_guard.
18225 2002-02-25 Akim Demaille <akim@epita.fr>
18227 * src/getargs.c (version): Give the name of the authors, and use a

18256 2002-02-14 Paul Eggert <eggert@twinsun.com>
18258 Remove the support for C++ namespace cleanliness; it was
18259 causing more problems than it was curing, since it didn't work
18260 properly on some nonstandard C++ compilers. This can wait
18261 for a proper C++ parser.
18263 * NEWS: Document this.
18264 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
18265 of C++, as it's treated like C now.

18279 2002-02-13 Andreas Schwab <schwab@suse.de>
18281 * src/output.c (output_rule_data): Don't output NULL, it might
18282 not be defined yet.
18284 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
18286 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.

18301 * tests/input.at: New.
18303 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18305 * data/bison.c++: Replace some direct m4 expansions by constants. Be
18306 more consistent when naming methods and variables. Put preprocessor
18307 directives around tables only needed for debugging.
18309 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18311 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
18313 (yy::b4_name::parse): Use print_.
18315 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18317 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
18319 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
18321 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
18323 (yy::b4_name::parse): Build verbose error messages, and use error_.
18325 2002-02-06 Robert Anisko <robert@lrde.epita.fr>

18329 2002-02-06 Robert Anisko <robert@lrde.epita.fr>

18332 not expanded by m4.
18334 2002-02-05 Akim Demaille <akim@epita.fr>
18336 * data/bison.c++: Adjust to the M4 back end.
18337 More is certainly needed.
18339 2002-02-05 Akim Demaille <akim@epita.fr>
18341 Give a try to M4 as a back end.
18343 * lib/readpipe.c: New, from wdiff.
18344 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
18346 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
18347 specific values. Now it is m4 that performs the lookup.
18348 * src/parse-skel.y: Remove.
18349 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
18350 * src/output.c (actions_output, guards_output)
18351 (token_definitions_output): No longer keeps track of the output
18352 line number, hence remove the second argument.
18353 (guards_output): Check against the guard member of a rule, not the
18356 (output_skeleton): Don't look for the skeleton location, let m4 do
18358 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
18360 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
18361 (prepare): Given that for the time being changesyntax is not
18362 usable in M4, rename the muscles using `-' to `_'.
18363 Define `defines_flag', `output_parser_name' and `output_header_name'.
18364 * src/output.h (actions_output, guards_output)
18365 (token_definitions_output): Adjust prototypes.
18366 * src/scan-skel.l: Instead of scanning the skeletons, it now
18367 processes the output of m4: `__oline__' and `#output'.
18368 * data/bison.simple: Adjust to be used by M4(sugar).
18369 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
18371 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
18372 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
18373 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
18374 shamelessly stolen from CVS Autoconf.
18376 2002-02-05 Akim Demaille <akim@epita.fr>
18378 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
18379 * configure.in: Check for the declarations of free and malloc.
18380 * src/muscle_tab.c: Adjust.
18382 2002-02-05 Akim Demaille <akim@epita.fr>
18384 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
18385 which have no values.
18387 2002-02-05 Akim Demaille <akim@epita.fr>
18389 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
18392 2002-01-29 Paul Eggert <eggert@twinsun.com>
18394 * src/bison.simple (YYSIZE_T): Do not define merely because
18395 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
18396 On some platforms, <alloca.h> does not declare YYSTD (size_t).
18398 2002-01-27 Akim Demaille <akim@epita.fr>
18400 Fix `%nonassoc and eof'.
18402 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
18403 which were not properly copied! Replace
18404 memcpy (res->errs, src->errs, src->nerrs);
18406 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
18408 * tests/regression.at (%nonassoc and eof): Adjust to newest
18409 Autotest: `.' is not in the PATH.
18411 2002-01-27 Akim Demaille <akim@epita.fr>
18413 * tests/sets.at (AT_EXTRACT_SETS): New.
18414 (Nullable): Use it.
18417 2002-01-26 Akim Demaille <akim@epita.fr>
18419 * tests/actions.at, tests/calc.at, tests/headers.at,
18420 * tests/torture.at: Adjust to the newest Autotest which no longer
18421 forces `.' in the PATH.
18423 2002-01-25 Akim Demaille <akim@epita.fr>
18425 * tests/regression.at (%nonassoc and eof): New.
18426 Suggested by Robert Anisko.
18428 2002-01-24 Akim Demaille <akim@epita.fr>
18430 Bison dumps core when trying to complain about broken input files.
18431 Reported by Cris van Pelt.
18433 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
18434 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
18436 (Invalid inputs): Strengthen: exercise parse_percent_token.
18438 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
18440 * src/Makefile.am: Add bison.c++.
18441 * src/bison.c++: New skeleton.
18443 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
18447 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
18449 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
18451 2002-01-20 Marc Autret <marc@gnu.org>
18453 * src/files.c (compute_output_file_names): Fix
18455 2002-01-20 Marc Autret <marc@gnu.org>
18457 * tests/output.at: New test.
18458 * src/files.c (compute_base_names): Don't map extensions when
18459 the YACC flag is set, use defaults.
18460 Reported by Evgeny Stambulchik.
18462 2002-01-20 Marc Autret <marc@gnu.org>
18464 * src/system.h: Need to define __attribute__ away for non-GCC
18465 compilers as well (i.e., the vendor C compiler).
18466 Suggested by Albert Chin-A-Young.
18468 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
18470 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
18471 canonical definition.
18472 * src/system.h: Use the canonical definition for PARAMS (avoids
18473 a conflict with the macro from lib/hash.h).
18475 2002-01-11 Akim Demaille <akim@epita.fr>
18477 * configure.in: Use AC_FUNC_STRNLEN.
18478 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
18480 2002-01-09 Akim Demaille <akim@epita.fr>
18482 * src/files.c, src/files.h (output_infix): New.
18483 (tab_extension): Remove.
18484 (compute_base_names): Compute the former, drop the latter.
18485 * src/output.c (prepare): Insert the muscles `output-infix', and
18487 * src/parse-skel.y (string, string.1): New.
18488 (section.header): Use it.
18489 (section.yacc): Remove.
18490 (prefix): Remove too.
18491 * src/scan-skel.l: Adjust.
18492 * src/bison.simple, src/bison.hairy: Adjust.
18494 2002-01-09 Akim Demaille <akim@epita.fr>
18496 * configure.in (WERROR_CFLAGS): Compute it.
18497 * src/Makefile.am (CFLAGS): Pass it.
18498 * tests/atlocal.in (CFLAGS): Idem.
18499 * src/files.c: Fix a few warnings.
18500 (get_extension_index): Remove, unused.
18502 2002-01-08 Akim Demaille <akim@epita.fr>
18504 * src/getargs.c (AS_FILE_NAME): New.
18505 (getargs): Use it to convert DOSish file names.
18506 * src/files.c (base_name): Rename as full_base_name to avoid
18507 clashes with `base_name ()'.
18508 (filename_split): New.
18509 (compute_base_names): N-th rewrite, using filename_split.
18511 2002-01-08 Akim Demaille <akim@epita.fr>
18513 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
18514 New, stolen from the Fileutils 4.1.
18515 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
18516 * configure.in: Check for the presence of memrchr, and of its
18519 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
18521 * lib/hash.h (__P): Added definition for this macro.
18522 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
18523 BUILT_SOURCES, to ensure they are generated first.
18524 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
18525 %error-verbose to allow bootstrapping with bison 1.30x.
18527 2002-01-06 Akim Demaille <akim@epita.fr>
18529 * src/reader.c (parse_braces): Don't fetch the next char, the
18530 convention is to fetch on entry.
18531 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
18532 'switch' without a following semicolon.
18533 * tests/regression.at (braces parsing): New.
18535 2002-01-06 Akim Demaille <akim@epita.fr>
18537 Bison is dead wrong in its RR conflict reports.
18539 * tests/torture.at (GNU Cim Grammar): New.
18540 * src/conflicts.c (count_rr_conflicts): Fix.
18542 2002-01-06 Akim Demaille <akim@epita.fr>
18544 Creating package.m4 from configure.ac causes too many problems.
18546 * tests/Makefile.am (package.m4): Create it by hand,
18547 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
18549 2002-01-06 Akim Demaille <akim@epita.fr>
18551 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
18554 2002-01-04 Paul Eggert <eggert@twinsun.com>
18556 * doc/bison.texinfo (Debugging):
18557 Remove YYSTDERR; it's no longer defined or used.
18558 Also, s/cstdio.h/cstdio/.
18560 2002-01-03 Akim Demaille <akim@epita.fr>
18562 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
18564 2002-01-03 Akim Demaille <akim@epita.fr>
18566 * src/parse-skel.y (process_skeleton): Don't bind the parser's
18567 tracing code to --trace, wait for a better --trace option, with
18570 2002-01-03 Akim Demaille <akim@epita.fr>
18572 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
18573 The ISO C++ standard is extremely clear about it: stderr is
18574 considered a macro, not a regular symbol (see table 94 `Header
18575 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
18576 Therefore std:: does not apply to it. It still does with fprintf.
18577 Also, s/cstdio.h/cstdio/.
18579 2002-01-03 Akim Demaille <akim@epita.fr>
18581 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
18582 for non system headers.
18584 2002-01-02 Akim Demaille <akim@epita.fr>
18586 Equip the skeleton chain with location tracking, runtime trace,
18587 pure parser and scanner.
18589 * src/parse-skel.y: Request a pure parser, locations, and prefix
18591 (%union): Having several members with the same type does not help
18592 type mismatches, simplify.
18593 (YYPRINT, yyprint): New.
18594 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
18595 (skel_error): this.
18597 * src/scan-skel.l: Adjust to these changes.
18598 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
18599 (LOCATION_PRINT, skel_control_t): New.
18601 2001-12-30 Akim Demaille <akim@epita.fr>
18603 * src/parse-skel.y: Get rid of the shift/reduce conflict:
18604 replace `gb' with BLANKS.
18605 * src/scan-skel.l: Adjust.
18607 2001-12-30 Akim Demaille <akim@epita.fr>
18609 * src/system.h: We don't need nor want bcopy.
18610 Throw away MS-DOS crap: we don't need getpid.
18611 * configure.in: We don't need strndup. It was even causing
18612 problems: because Flex includes the headers *before* us,
18613 _GNU_SOURCE is not defined by config.h, and therefore strndup was
18615 * lib/xstrndup.c: New.
18616 * src/scan-skel.l: Use it.
18617 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
18618 * src/parse-skel.y: Use %directives instead of #defines.
18620 2001-12-30 Akim Demaille <akim@epita.fr>
18622 * src/skeleton.h: New.
18623 * src/output.c (output_parser, output_master_parser): Remove, dead
18625 * src/output.h (get_lines_number, actions_output, guards_output)
18626 (token_definitions_output): Prototype them.
18627 * src/parse-skel.y: Add the license notice.
18628 Include output.h and skeleton.h.
18629 (process_skeleton): Returns void, and takes a single parameter.
18630 * src/scan-skel.l: Add the license notice.
18631 Include skeleton.h.
18632 Don't use %option yylineno: it seems that then Flex imagines
18633 REJECT has been used, and therefore it won't reallocate its
18634 buffers (which makes no other sense to me than a bug). It results
18635 in warnings for `unused: yy_flex_realloc'.
18637 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
18639 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
18640 (MUSCLE_INSERT_PREFIX): ...to there.
18641 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
18642 (MUSCLE_INSERT_PREFIX): Move from here...
18644 * src/bison.hairy: Add a section directive. Put braces around muscle
18645 names. This parser skeleton is still broken, but Bison should not
18646 choke on a bad muscle 'syntax'.
18647 * src/bison.simple: Add a section directive. Put braces around muscle
18650 * src/files.h (strsuffix, stringappend): Add declarations.
18651 (tab_extension): Add declaration.
18652 (short_base_name): Add declaration.
18654 * src/files.c (strsuffix, stringappend): No longer static. These
18655 functions are used in the skeleton parser.
18656 (tab_extension): New.
18657 (compute_base_names): Use the computations done in this function
18658 to guess if the generated parsers should have '.tab' in their
18660 (short_base_name): No longer static.
18662 * src/output.c (output_skeleton): New.
18663 (output): Disable call to output_master_parser, and give a try to
18664 a new skeleton handling system.
18665 (guards_output, actions_output): No longer static.
18666 (token_definitions_output, get_lines_number): No longer static.
18668 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
18670 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
18673 * src/parse-skel.y: New file.
18674 * src/scan-skel.l: New file.
18676 2001-12-29 Akim Demaille <akim@epita.fr>
18678 %name-prefix is broken.
18680 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
18681 Adjust all dependencies.
18682 * tests/headers.at (export YYLTYPE): Strengthen this test: use
18685 Renaming yylval but not yylloc is not consistent. Now we do.
18687 * src/bison.simple: Prefix yylloc if used.
18688 * doc/bison.texinfo (Decl Summary): Document that.
18690 2001-12-29 Akim Demaille <akim@epita.fr>
18692 * doc/bison.texinfo: Promote `%long-directive' over
18694 Remove all references to fixed-output-files, yacc is enough.
18696 2001-12-29 Akim Demaille <akim@epita.fr>
18698 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
18699 user prologue. These are defaults.
18700 * tests/actions.at (Mid-rule actions): Make sure the user can
18701 define YYDEBUG and YYERROR_VERBOSE.
18703 2001-12-29 Akim Demaille <akim@epita.fr>
18705 * src/output.c (header_output): Don't forget to export YYLTYPE and
18707 * tests/headers.at (export YYLTYPE): New, make sure it does.
18708 * tests/regression.at (%union and --defines, Invalid CPP headers):
18710 * tests/headers.at: here.
18712 2001-12-29 Akim Demaille <akim@epita.fr>
18714 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
18716 2001-12-29 Akim Demaille <akim@epita.fr>
18718 * tests/actions.at (Mid-rule actions): Output on a single line
18719 instead of several.
18721 2001-12-29 Akim Demaille <akim@epita.fr>
18723 * doc/bison.texinfo: Formatting changes.
18725 2001-12-29 Akim Demaille <akim@epita.fr>
18727 Don't store the token defs in a muscle, just be ready to output it
18728 on command. Now possible via `symbols'. Fixes a memory leak.
18730 * src/output.c (token_definitions_output): New.
18731 (output_parser, header_output): Use it.
18732 * src/reader.c (symbols_save): Remove.
18734 2001-12-29 Akim Demaille <akim@epita.fr>
18736 * src/bison.simple: Do not provide a default for YYSTYPE and
18737 YYLTYPE before the user's prologue. Otherwise it's hardly... a
18740 2001-12-29 Akim Demaille <akim@epita.fr>
18742 Mid-rule actions are simply... ignored!
18744 * src/reader.c (readgram): Be sure to attach mid-rule actions to
18745 the empty-rule associated to the dummy symbol, not to the host
18747 * tests/actions.at (Mid-rule actions): New.
18749 2001-12-29 Akim Demaille <akim@epita.fr>
18753 * src/reader.c (reader): Free grammar.
18755 2001-12-29 Akim Demaille <akim@epita.fr>
18759 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
18760 since it allocates it for each state, although only one is needed.
18761 (allocate_storage): Do it here.
18763 2001-12-29 Akim Demaille <akim@epita.fr>
18765 * src/options.h, src/options.c (create_long_option_table): Rename
18767 (long_option_table_new): this, with a clearer prototype.
18768 (percent_table): Remove, unused,
18769 * src/getargs.c (getargs): Adjust.
18771 2001-12-29 Akim Demaille <akim@epita.fr>
18773 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
18774 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
18777 2001-12-29 Akim Demaille <akim@epita.fr>
18779 * src/lalr.c (build_relations): Rename `states' as `states1'.
18780 Sorry, I don't understand exactly what it is, no better name...
18782 2001-12-29 Akim Demaille <akim@epita.fr>
18784 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
18785 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

18794 2001-12-29 Akim Demaille <akim@epita.fr>
18796 * src/reader.c, src/reader.h (user_toknums): Remove.
18797 Adjust all users to use symbols[i]->user_token_number.
18799 2001-12-29 Akim Demaille <akim@epita.fr>
18801 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
18802 Adjust all users to use symbols[i]->prec or ->assoc.
18804 2001-12-29 Akim Demaille <akim@epita.fr>
18806 * src/reader.c, src/reader.h (tags): Remove.
18807 Adjust all users to use symbols[i]->tag.
18809 2001-12-29 Akim Demaille <akim@epita.fr>
18811 * src/gram.h, src/gram.c (symbols): New, similar to state_table
18813 * src/reader.c (packsymbols): Fill this table.
18815 * src/conflicts.c (resolve_sr_conflict): Adjust.
18816 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
18818 Use symbols[i]->tag instead of tags[i].
18820 2001-12-29 Akim Demaille <akim@epita.fr>
18822 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
18823 In addition, put a comment in there, to replace...
18824 * tests/regression.at (%union and C comments): Remove.
18826 2001-12-29 Akim Demaille <akim@epita.fr>
18828 * tests/regression.at (Web2c Actions): Blindly move the actual
18829 output as expected output. The contents *seem* right to me, but I
18830 can't pretend reading perfectly parser tables... Nonetheless, all
18831 the other tests pass correctly, the table look OK, even though the
18832 presence of `$axiom' is to be noted: AFAICS it is useless (but
18835 2001-12-29 Akim Demaille <akim@epita.fr>
18837 * src/reader.c (readgram): Don't add the rule 0 if there were no
18838 rules read. In other words, add it _after_ having performed
18839 grammar sanity checks.
18840 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
18842 2001-12-29 Akim Demaille <akim@epita.fr>
18844 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
18845 visible, and some states have now a different number.
18847 2001-12-29 Akim Demaille <akim@epita.fr>
18849 * src/reader.c (readgram): Bind the initial rule's lineno to that
18851 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18852 (Solved SR Conflicts): Adjust rule 0's line number.
18854 2001-12-29 Akim Demaille <akim@epita.fr>
18856 Fix the `GAWK Grammar' failure.
18858 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18859 the reductions of the first state which was mistakenly confused
18860 with the final state because precisely final_state was initialized
18862 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18863 now noticed by Bison.
18864 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18865 have a reduction on $default.
18867 2001-12-29 Akim Demaille <akim@epita.fr>
18869 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18871 * src/closure.c (print_closure): Likewise.
18872 * src/derives.c (print_derives): Likewise.
18873 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18876 2001-12-29 Akim Demaille <akim@epita.fr>
18878 * src/lalr.c (lookaheads_print): New.
18879 (lalr): Call it when --trace-flag.
18880 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18883 2001-12-29 Akim Demaille <akim@epita.fr>
18885 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18886 when walking through ritem, even via rule->rhs.
18887 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18888 (useful_production, useless_nonterminals): Likewise.
18889 (reduce_grammar_tables): Likewise, plus update nritems.
18890 * src/nullable.c (set_nullable): Likewise.
18891 * src/lalr.c (build_relations): Likewise.
18892 * tests/sets.at (Nullable): Adjust.
18893 Fortunately, now, the $axiom is no longer nullable.
18895 2001-12-29 Akim Demaille <akim@epita.fr>
18897 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
18899 * src/gram.c (ritem_longest_rhs): Likewise.
18900 * src/reduce.c (nonterminals_reduce): Likewise.
18901 * src/print_graph.c (print_graph): Likewise.
18902 * src/output.c (output_rule_data): Likewise.
18903 * src/nullable.c (set_nullable): Likewise.
18905 2001-12-29 Akim Demaille <akim@epita.fr>
18907 * src/output.c: Comment changes.
18909 2001-12-27 Paul Eggert <eggert@twinsun.com>
18911 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18912 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18913 Sparc, as they were causing more porting problems than the
18914 (minor) performance improvement was worth.
18916 Also, catch up with 1.31's YYSTD.
18918 2001-12-27 Akim Demaille <akim@epita.fr>
18920 * src/output.c (output_gram): Rely on nritems, not the
18921 0-sentinel. See below.
18922 Use -1 as separator, not 0.
18923 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18924 Rely on -1 as separator in yyrhs, instead of 0.
18925 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18926 twice `Now at end of input', therefore there are two lines less to
18929 2001-12-27 Akim Demaille <akim@epita.fr>
18931 * tests/regression.at (Unresolved SR Conflicts):
18932 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18935 2001-12-27 Akim Demaille <akim@epita.fr>
18937 * src/LR0.c (new_state): Recognize the final state by the fact it
18938 is reached by eoftoken.
18939 (insert_start_shifting_state, insert_eof_shifting_state)
18940 (insert_accepting_state, augment_automaton): Remove, since now
18941 these states are automatically computed from the initial state.
18942 (generate_states): Adjust.
18943 * src/print.c: When reporting a rule number to the user, substract
18944 1, so that the axiom rule is rule 0, and the first user rule is 1.
18945 * src/reduce.c: Likewise.
18946 * src/print_graph.c (print_core): For the time being, just as for
18947 the report, depend upon --trace-flags to dump the full set of
18949 * src/reader.c (readgram): Once the grammar read, insert the rule
18950 0: `$axiom: START-SYMBOL $'.
18951 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18952 number of the states has changed (the final state is no longer
18953 necessarily the last), catch up.
18955 2001-12-27 Akim Demaille <akim@epita.fr>
18957 Try to make the use of the eoftoken valid. Given that its value
18958 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18959 is used instead of > 0 where appropriate, (ii), depend upon nritems
18960 instead of the 0-sentinel.
18962 * src/gram.h, src/gram.c (nritems): New.
18963 Expected to be duplication of nitems, but for the time being...
18964 * src/reader.c (packgram): Assert nritems and nitems are equal.
18965 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18966 * src/closure.c (print_closure, print_fderives): Likewise.

18973 * src/main.c (main): If there are complains after grammar
18974 reductions, then output the report anyway if requested, then die.
18975 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18976 * src/reader.c (eoftoken): New.
18977 (parse_token_decl): If the token being defined has value `0', it
18979 (packsymbols): No longer hack `tags' to insert `$' by hand.
18980 Be sure to preserve the value of the eoftoken.
18981 (reader): Make sure eoftoken is defined.
18982 Initialize nsyms to 0: now eoftoken is created just like the others.
18983 * src/print.c (print_grammar): Don't special case the eof token.
18984 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18985 lie anyway, albeit pleasant.
18986 * tests/calc.at: Exercise error messages with eoftoken.
18987 Change the grammar so that empty input is invalid.
18988 Adjust expectations.
18989 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18991 2001-12-27 Akim Demaille <akim@epita.fr>
18993 * configure.in: Check the protos of strchr ans strspn.
18994 Replace strchr if needed.
18995 * src/system.h: Provide the protos of strchr, strspn and memchr if
18997 * lib/strchr.c: New.
18998 * src/reader.c (symbols_save): Use strchr.
19000 2001-12-27 Akim Demaille <akim@epita.fr>
19002 * src/print.c, src/print_graph.c (escape): New.
19003 Use it to quote the TAGS outputs.
19004 * src/print_graph.c (print_state): Now errors are in red, and
19005 reductions in green.
19006 Prefer high to wide: output the state number on a line of its own.
19008 2001-12-27 Akim Demaille <akim@epita.fr>
19010 * src/state.h, src/state.c (reductions_new): New.
19011 * src/LR0.c (set_state_table): Let all the states have a
19012 `reductions', even if reduced to 0.

19064 * src/output.c (output): Adjust.
19065 * src/reader.c (parse_braces): New, factoring...
19066 (copy_action, copy_guard): these two which are renamed as...
19067 (parse_action, parse_guard): these.
19068 As a voluntary consequence, using braces around guards is now
19071 2001-12-27 Akim Demaille <akim@epita.fr>
19073 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
19074 * src/reader.c (symbol_list): `guard' and `guard_line' are new
19076 (symbol_list_new): Adjust.
19077 (copy_action): action_line is the first line, not the last.
19078 (copy_guard): Just as for actions, store the `action' only, not
19079 the switch/case/break flesh.
19080 Don't parse the user action that might follow the guard, let...
19081 (readgram): do it, i.e., now, there can be an action after a
19083 In other words the guard is just explicitly optional.
19084 (packgram): Adjust.
19085 * src/output.c (guards_output): New.
19086 (output_parser): Call it when needed.
19087 (output): Also free the guard and attrs obstacks.
19088 * src/files.c, src/files.h (obstack_save): Remove.
19089 (output_files): Remove.
19090 As a result, if one needs the former `.act' file, using an
19091 appropriate skeleton which requires actions and guards is now
19093 * src/main.c (main): Adjust.
19094 * tests/semantic.at: New.
19095 * tests/regression.at: Use `input.y' as input file name.
19096 Avoid 8+3 problems by requiring input.c when the test needs the

19101 * src/reader.c (symbol_list_new): Be sure to initialize all the
19104 2001-12-27 Akim Demaille <akim@epita.fr>
19106 All the hacks using a final pseudo state are now useless.
19108 * src/LR0.c (set_state_table): state_table holds exactly nstates.
19109 * src/lalr.c (nLA): New.
19110 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
19111 instead of lookaheadsp from the pseudo state (nstate + 1).
19113 2001-12-27 Akim Demaille <akim@epita.fr>
19115 * src/output.c (action_row, token_actions): Use a state_t instead
19116 of a integer, and nlookaheads instead of the following state's
19119 2001-12-27 Akim Demaille <akim@epita.fr>
19121 * src/conflicts.c (log_resolution, flush_shift)
19122 (resolve_sr_conflict, set_conflicts, solve_conflicts)
19123 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
19124 (conflicts_print, print_reductions): Use a state_t instead of an
19125 integer when referring to a state.
19126 As much as possible, depend upon nlookaheads, instead of the
19127 `lookaheadsp' member of the following state (since lookaheads of
19128 successive states are successive, the difference between state n + 1
19129 and n served as the number of lookaheads for state n).
19130 * src/lalr.c (add_lookback_edge): Likewise.
19131 * src/print.c (print_core, print_actions, print_state)
19132 (print_results): Likewise.
19133 * src/print_graph.c (print_core, print_actions, print_state)
19134 (print_graph): Likewise.
19135 * src/conflicts.h: Adjust.
19137 2001-12-27 Akim Demaille <akim@epita.fr>
19139 * src/bison.hairy: Formatting/comment changes.
19141 Remove `register' indications.
19142 Add plenty of `static'.
19144 2001-12-27 Akim Demaille <akim@epita.fr>
19146 * src/output.c (prepare): Drop the muscle `ntbase' which
19147 duplicates ntokens.
19148 * src/bison.simple: Formatting/comment changes.
19149 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
19150 is an undocumented synonym.
19152 2001-12-22 Akim Demaille <akim@epita.fr>
19154 * src/output.c (output_table_data): Change the prototype to use
19155 `int' for array ranges: some invocations do pass an int, not a
19157 Reported by Wayne Green.
19159 2001-12-22 Akim Demaille <akim@epita.fr>
19161 Some actions of web2c.y are improperly triggered.
19162 Reported by Mike Castle.
19164 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
19165 * tests/regression.at (Web2c): Rename as...
19166 (Web2c Report): this.
19167 (Web2c Actions): New.
19169 2001-12-22 Akim Demaille <akim@epita.fr>
19171 Reductions in web2c.y are improperly reported.
19172 Reported by Mike Castle.
19174 * src/conflicts.c (print_reductions): Fix.
19175 * tests/regression.at (Web2c): New.
19177 2001-12-18 Akim Demaille <akim@epita.fr>
19179 Some host fail on `assert (!"foo")', which expands to
19180 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
19181 Reported by Nelson Beebee.
19183 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
19184 `#define it_succeeded 0' and `assert (it_succeeded)'.
19186 2001-12-17 Marc Autret <autret_m@epita.fr>
19188 * src/bison.simple: Don't hard code the skeleton line and filename.
19189 * src/output.c (output_parser): Rename 'line' as 'output_line'.
19190 New line counter 'skeleton_line' (skeleton-line muscle).
19192 2001-12-17 Paul Eggert <eggert@twinsun.com>
19194 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
19195 YYDEBUG must be defined to a nonzero value.
19197 * src/bison.simple (yytname): Do not assume that the user defines
19198 YYDEBUG to a properly parenthesized expression.
19200 2001-12-17 Akim Demaille <akim@epita.fr>
19202 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
19203 nlookaheads is a new member.
19205 * src/lalr.h (nlookaheads): Remove this orphan declaration.
19206 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
19209 2001-12-17 Akim Demaille <akim@epita.fr>
19211 * src/files.h, src/files.c (open_files, close_files): Remove.
19212 * src/main.c (main): Don't open/close files, nor invoke lex_free,
19214 * src/reader.c (reader): Do it.
19216 2001-12-17 Akim Demaille <akim@epita.fr>
19218 * src/conflicts.c (print_reductions): Formatting changes.
19220 2001-12-17 Akim Demaille <akim@epita.fr>
19222 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
19223 (flush_reduce): New.
19224 (resolve_sr_conflict): Adjust.
19226 2001-12-17 Akim Demaille <akim@epita.fr>
19228 * src/output.c (output_obstack): Be static and rename as...
19229 (format_obstack): this, to avoid any confusion with files.c's
19231 * src/reader.h (muscle_obstack): Move to...
19232 * src/output.h: here, since it's defined in output.c.
19234 2001-12-17 Akim Demaille <akim@epita.fr>
19236 * src/output.c (action_row, save_column, default_goto)
19237 (sort_actions, matching_state, pack_vector): Better variable
19240 2001-12-17 Akim Demaille <akim@epita.fr>
19242 * src/output.c: Various formatting changes.
19244 2001-12-17 Akim Demaille <akim@epita.fr>
19246 * src/files.c (output_files): Free the output_obstack.
19247 * src/main.c (main): Call print and print_graph conditionally.
19248 * src/print.c (print): Work unconditionally.
19249 * src/print_graph.c (print_graph): Work unconditionally.
19250 * src/conflicts.c (log_resolution): Output only if verbose_flag.
19252 2001-12-16 Marc Autret <autret_m@epita.fr>
19254 * src/output.c (actions_output): Fix. When we use %no-lines,
19255 there is one less line per action.
19257 2001-12-16 Marc Autret <autret_m@epita.fr>
19259 * src/bison.simple: Remove a useless #line directive.
19260 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
19261 * src/output.c (get_lines_number): New.
19262 (output_parser): Adjust, now takes care about the lines of a
19264 Fix line numbering.
19265 (actions_output): Computes the number of lines taken by actions.
19266 (output_master_parser): Insert new skeleton which is the name of
19267 the output parser file name.
19269 2001-12-15 Marc Autret <autret_m@epita.fr>
19271 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
19273 2001-12-15 Marc Autret <autret_m@epita.fr>
19275 * src/output.c (output_gram): Keep track of the hairy one.
19277 2001-12-15 Akim Demaille <akim@epita.fr>
19279 Make `make distcheck' work.
19281 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
19282 system.h which uses libgettext.h.
19284 2001-12-15 Akim Demaille <akim@epita.fr>
19286 * src/nullable.c (set_nullable): Useless rules must be skipped,
19287 otherwise, since we range over their symbols, we might look at a
19288 nonterminal which no longer ``exists'', i.e., it is not counted in
19289 `nvars', hence we overflow our arrays.
19291 2001-12-15 Akim Demaille <akim@epita.fr>
19293 The header can also be produced directly, without any obstack!
19296 * src/files.c, src/files.h (defines_obstack): Remove.
19297 (compute_header_macro): Global.
19298 (defines_obstack_save): Remove.
19299 * src/reader.c (parse_union_decl): No longer output to
19300 defines_obstack: its content can be found in the `stype' muscle
19302 (output_token_translations): Merge into...
19303 (symbols_output): this.
19305 (symbols_save): this.
19307 * src/output.c (header_output): New.
19310 2001-12-15 Akim Demaille <akim@epita.fr>
19312 * src/reader.c (parse_union_decl): Instead of handling two obstack
19313 simultaneously, use one to define the `stype' muscle, and use the
19314 value of the latter to fill defines_obstack.
19315 (copy_comment): Remove.
19316 (copy_comment2): Work for a single obstack.
19318 (copy_comment): this.
19320 2001-12-15 Akim Demaille <akim@epita.fr>
19322 * src/lex.c, src/lex.h (xgetc): No longer static.
19323 * src/reader.c (parse_union_decl): Revamp.
19325 2001-12-15 Akim Demaille <akim@epita.fr>
19327 Still making progress in separating Bison into (i) input, (ii)
19328 process, (iii) output: now we can directly output the parser file
19329 without using table_obstack at all.
19331 * src/files.c, src/files.h (table_obstack): Bye bye.
19332 (parser_file_name): New.
19333 * src/files.c (compute_output_file_names): Compute it.
19334 * src/output.c (actions_output, output_parser)
19335 (output_master_parser): To a file instead of an obstack.
19337 2001-12-15 Akim Demaille <akim@epita.fr>
19339 Attach actions to rules, instead of pre-outputting them to
19342 * src/gram.h (rule_t): action and action_line are new members.
19343 * src/reader.c (symbol_list): Likewise.
19344 (copy_action): Save the actions within the rule.
19345 (packgram): Save them in rule_table.
19346 * src/output.c (actions_output): New.
19347 (output_parser): Use it on `%%actions'.
19348 (output_rule_data): Don't free rule_table.
19350 (prepare): Don't save the `action' muscle.
19351 * src/bison.simple: s/%%action/%%actions/.
19353 2001-12-15 Akim Demaille <akim@epita.fr>
19355 * src/reader.c (copy_action): When --yacc, don't append a `;'
19356 to the user action: let it fail if lacking.
19357 Suggested by Arnold Robbins and Tom Tromey.
19359 2001-12-14 Akim Demaille <akim@epita.fr>
19361 * src/lex.c (literalchar): Simply return the char you decoded, non
19362 longer mess around with obstacks and int pointers.
19363 Adjust all callers.
19365 2001-12-14 Akim Demaille <akim@epita.fr>
19367 * src/lex.c (literalchar): Don't escape the special characters,
19368 just decode them, and keep them as char (before, eol was output as
19369 the 2 char string `\n' etc.).
19370 * src/output.c (output_rule_data): Use quotearg to output the
19373 2001-12-13 Paul Eggert <eggert@twinsun.com>
19375 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
19376 Do not infringe on the global user namespace when using C++.
19377 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
19378 All uses of `fprintf' and `stderr' changed.
19380 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
19382 2001-12-13 Akim Demaille <akim@epita.fr>
19384 The computation of nullable is broken: it doesn't handle empty
19387 * tests/torture.at (GNU AWK Grammar): New.
19388 * tests/sets.at (Nullable): New.
19389 * src/nullable.c (set_nullable): Instead of blindly looping over
19390 `ritems', loop over the rules, and then over their rhs's.
19392 Work around Autotest bugs.
19394 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
19395 frame, because Autotest understand lines starting with a `+' as
19396 traces from the shell. Then, they are not processed properly.
19397 Admittedly an Autotest bug, but we don't have time to wait for
19398 Autotest to catch up.
19399 * tests/regression.at (Broken Closure): Adjust to the new table
19402 * tests/sets.at: here.
19404 2001-12-13 Akim Demaille <akim@epita.fr>
19406 * src/closure.c (closure): Use nrules instead of playing tricks
19407 with BITS_PER_WORD.
19409 2001-12-13 Akim Demaille <akim@epita.fr>
19411 * src/print.c (print_actions): Output the handling of `$' as the
19412 traces do: shifting the token EOF. Before EOF was treated as a
19414 * tests/regression.at: Adjust some tests.
19415 * src/print_graph.c (print_core): Complete the set of items via
19416 closure. The next-to-final and final states are still unsatisfying,
19417 but that's to be addressed elsewhere.
19418 No longer output the rule numbers, but do output the state number.
19419 A single loop for the shifts + gotos is enough, but picked a
19420 distinct color for each.
19421 (print_graph): Initialize and finalize closure.
19423 2001-12-13 Akim Demaille <akim@epita.fr>
19425 * src/reader.c (readgram): Remove dead code, an strip useless
19427 (get_type): Remove, unused.
19429 2001-12-12 Akim Demaille <akim@epita.fr>
19431 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
19432 on that of lib/error.c.
19434 2001-12-12 Akim Demaille <akim@epita.fr>
19436 Some hosts don't like `/' in includes.
19438 * src/system.h: Include libgettext.h without qualifying the path.
19439 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
19442 2001-12-11 Marc Autret <autret_m@epita.fr>
19444 * src/output.c (output_parser): Remove useless muscle.
19446 2001-12-11 Marc Autret <autret_m@epita.fr>
19448 * src/bison.simple: Remove #line just before %%epilogue. It
19449 is now handled in ...
19450 * src/reader.c (read_additionnal_code): Add the output of a
19451 #line for the epilogue.
19453 2001-12-10 Marc Autret <autret_m@epita.fr>
19455 * src/reader.c (copy_definition): Re-use CPP-outed code which
19456 replace precedent remove.
19457 * src/bison.simple: Remove #line before %%prologue because
19458 %%input-line is wrong at this time.
19460 2001-12-10 Marc Autret <autret_m@epita.fr>
19462 * src/reader.c (symbols_output): Clean up.
19463 * src/output.c (output_gram, output): Clean up.
19465 2001-12-10 Akim Demaille <akim@epita.fr>
19467 * src/lalr.c (initialize_lookaheads): New. Extracted from...
19468 * src/LR0.c (set_state_table): here.
19469 * src/lalr.c (lalr): Call it.
19471 2001-12-10 Akim Demaille <akim@epita.fr>
19473 * src/state.h (shifts): Remove the `number' member: shifts are
19474 attached to state, hence no longer need to be labelled with a
19477 2001-12-10 Akim Demaille <akim@epita.fr>
19479 Now that states have a complete set of members, the linked list of
19480 shifts is useless: just fill directly the state's shifts member.
19482 * src/state.h (shifts): Remove the `next' member.
19483 * src/LR0.c (first_state, last_state): Remove.
19484 Adjust the callers.
19485 (augment_automaton): Don't look for the shifts that must be added
19486 a shift on EOF: it is those of the state we looked for! But now,
19487 since shifts are attached, it is no longer needed to looking
19488 merely by its id: its number.
19490 2001-12-10 Akim Demaille <akim@epita.fr>
19492 * src/LR0.c (augment_automaton): Better variable locality.
19493 Remove an impossible branch: if there is a state corresponding to
19494 the start symbol being shifted, then there is shift for the start
19495 symbol from the initial state.
19497 2001-12-10 Akim Demaille <akim@epita.fr>
19499 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
19500 only when appropriate: when insert_start_shifting_state' is not
19502 * tests/regression.at (Rule Line Numbers): Adjust.
19504 2001-12-10 Akim Demaille <akim@epita.fr>
19506 * src/LR0.c (augment_automaton): Now that all states have shifts,
19507 merge the two cases addition shifts to the initial state.
19509 2001-12-10 Akim Demaille <akim@epita.fr>
19511 * src/lalr.c (set_state_table): Move to...
19513 * src/lalr.c (lalr): Don't call it...
19514 * src/LR0.c (generate_states): do it.
19515 * src/LR0.h (first_state): Remove, only the table is used.
19517 2001-12-10 Akim Demaille <akim@epita.fr>
19519 * src/LR0.h (first_shift, first_reduction): Remove.
19520 * src/lalr.c: Don't use first_shift: find shifts through the
19523 2001-12-10 Akim Demaille <akim@epita.fr>
19525 * src/LR0.c: Attach shifts to states as soon as they are
19527 * src/lalr.c (set_state_table): Instead of assigning shifts to
19528 state, just assert that the mapping was properly done.
19530 2001-12-10 Akim Demaille <akim@epita.fr>
19532 * src/LR0.c (insert_start_shift): Rename as...
19533 (insert_start_shifting_state): this.
19534 (insert_eof_shifting_state, insert_accepting_state): New.
19535 (augment_automaton): Adjust.
19536 Better locality of the variables.
19537 When looking if the start_symbol is shifted from the initial
19538 state, using `while (... symbol != start_symbol ...)' sounds
19539 better than `while (... symbol < start_symbol ...)': If fail
19540 to see how the order between symbols could be relevant!
19542 2001-12-10 Akim Demaille <akim@epita.fr>
19544 * src/getargs.h: Don't declare `spec_name_prefix' and
19545 `spec_file_prefix', declared by src/files.h.
19546 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
19547 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
19548 * src/output.c (prepare): Adjust.
19549 * src/reader.c (symbols_output): Likewise.
19550 * src/vmsgetargs.c: Vaguely adjust, but who cares?
19552 2001-12-10 Akim Demaille <akim@epita.fr>
19554 * src/muscle_tab.c (muscle_init): NULL is a better default than
19557 2001-12-10 Akim Demaille <akim@epita.fr>
19559 * src/reader.c (reader): Calling symbols_output once is enough.
19561 2001-12-10 Akim Demaille <akim@epita.fr>
19563 Now that states have a complete set of members, the linked list of
19564 reductions is useless: just fill directly the state's reductions
19567 * src/state.h (struct reductions): Remove member `number' and
19569 * src/LR0.c (first_reduction, last_reduction): Remove.
19570 (save_reductions): Don't link the new reductions, store them in
19572 * src/lalr.c (set_state_table): No need to attach reductions to
19573 states, it's already done.
19574 * src/output.c (output_actions): No longer free the shifts, then
19575 the reductions, then the states: free all the states and their
19578 2001-12-10 Akim Demaille <akim@epita.fr>
19580 * src/options.c (OPTN, DRTV, BOTH): New.
19581 (option_table): Use them.
19583 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
19584 the job of system.h.
19585 * src/options.c: Don't include stdio.h and xalloc.h for the same
19588 2001-12-10 Akim Demaille <akim@epita.fr>
19590 * src/output.c (output, prepare): Make sure the values of the
19591 muscles `action' and `prologue' are 0-terminated.
19593 2001-12-10 Akim Demaille <akim@epita.fr>
19595 Clean up GCC warnings.
19597 * src/reader.c (copy_action): `buf' is not used.
19598 (parse_skel_decl): Be static.
19599 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
19600 * src/options.h (create_long_option_table): Have a real prototype.
19601 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
19602 (hash_delete_at): Return const void *.
19603 Adjust casts to preserve the const.
19605 2001-12-10 Akim Demaille <akim@epita.fr>
19607 * configure.in: Require 2.52g.
19608 M4 is not needed, but AUTOM4TE is.
19609 * m4/m4.m4: Remove.
19610 * tests/Makefile.am: Adjust.
19612 2001-12-10 Akim Demaille <akim@epita.fr>
19614 One structure for states is enough, even though theoretically
19615 there are LR(0) states and LALR(1) states.
19617 * src/lalr.h (state_t): Remove.
19618 (state_table): Be state_t **, not state_t *.
19619 * src/state.h (core, CORE_ALLOC): Rename as...
19620 (state_t, STATE_ALLOC): this.
19621 Add the LALR(1) members: shifts, reductions, errs.
19622 * src/LR0.c (state_table): Rename as...

19628 2001-12-10 Akim Demaille <akim@epita.fr>
19630 Bison dumps core on bash.y.
19631 Reported by Pascal Bart.
19633 * src/warshall.c (bitmatrix_print): New.
19635 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
19636 j must be the outer loop.
19637 * tests/regression.at (Broken Closure): New.
19639 2001-12-05 Akim Demaille <akim@epita.fr>
19641 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
19643 Reported by Peter Hamorsky.
19645 2001-12-05 Akim Demaille <akim@epita.fr>

19648 (resolve_sr_conflict): Adjust.
19649 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
19651 (state_t.reductions, state_t.shifts): this.
19653 2001-12-05 Akim Demaille <akim@epita.fr>
19655 * src/reduce.c (reduce_grammar_tables): No longer disable the
19656 removal of useless rules via CPP but via `if (0)', so that the
19657 compiler still check the code is valid.
19658 For instance, it should have noticed `rline' no longer exists: use
19659 the `line' member of rule_t.
19660 * src/gram.c (dummy, rline): Remove, unused.
19662 2001-12-05 Akim Demaille <akim@epita.fr>
19664 * src/output.c (pack_vector): Use assert, not berror.
19665 * src/main.c (berror): Remove, unused.
19667 2001-12-05 Akim Demaille <akim@epita.fr>
19669 New experimental feature: if --verbose --trace output all the
19670 items of a state, not only its kernel.
19672 * src/print.c (print_core): If `trace_flag', then invoke closure
19673 before outputting the items of the state (print_core is no longer
19674 a correct name them).
19675 (print_results): Invoke new_closure/free_closure if needed.
19677 2001-12-05 Akim Demaille <akim@epita.fr>
19679 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.

19686 (closure): Use it for printing input and output.
19688 2001-12-05 Akim Demaille <akim@epita.fr>

19691 indexed by nonterminals.
19693 2001-12-05 Akim Demaille <akim@epita.fr>
19695 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

19713 * src/output.c (action_row): De-obfuscate
19714 using the good o' techniques: arrays not pointers, variable
19715 locality, BITISSET, RESETBIT etc.
19717 2001-12-05 Akim Demaille <akim@epita.fr>
19719 Pessimize the code to simplify it: from now on, all the states
19720 have a valid SHIFTS, which NSHIFTS is possibly 0.
19722 * src/LR0.c (shifts_new): Be global and move to..
19723 * src/state.c, src/state.h: here.
19724 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
19725 * src/print_graph: Adjust.
19727 2001-12-05 Akim Demaille <akim@epita.fr>
19729 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
19730 * src/conflicts.c: Use it.
19731 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
19732 incorrectly ``simplified''.
19734 2001-12-05 Akim Demaille <akim@epita.fr>
19736 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
19737 using the good o' techniques: arrays not pointers, variable
19738 locality, BITISSET, RESETBIT etc.

19742 * src/state.h (SHIFT_SYMBOL): New.

19772 2001-12-05 Akim Demaille <akim@epita.fr>

19790 * src/lalr.c (maxrhs): Move to...
19791 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
19792 * src/lalr.c (build_relations): Adjust.
19794 2001-12-05 Akim Demaille <akim@epita.fr>
19796 * src/lalr.c (transpose): Free the memory allocated to the
19797 argument, as it is replaced by the results by the unique caller.
19798 (build_relations): Merely invoke transpose: it handles the memory
19800 Improve variable locality.
19801 Avoid variables used as mere abbreviations.
19802 (compute_lookaheads): Use arrays instead of pointers.
19804 2001-12-05 Akim Demaille <akim@epita.fr>
19806 * src/lalr.c (initialize_F): Improve variable locality.
19807 Avoid variables used as mere abbreviations.

19820 2001-12-05 Akim Demaille <akim@epita.fr>
19822 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
19823 the handling of squeue.
19824 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19826 2001-12-05 Akim Demaille <akim@epita.fr>
19828 Because useless nonterminals are now kept alive (instead of being
19829 `destroyed'), we now sometimes examine them, and store information
19830 related to them. Hence we need to know their number, and adjust
19831 memory allocations.
19833 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19835 * src/LR0.c (allocate_itemsets): The memory allocated to
19836 `symbol_count' was used for two different purpose: once to count
19837 the number of occurrences of each symbol, and later reassigned to
19838 `shift_symbol', containing the symbol that can be shifted from a
19840 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19842 (new_itemsets): Allocate `shift_symbol' here.
19843 (allocate_itemsets): symbol_count includes useless nonterminals.
19844 Make room for them.
19845 (free_storage): Use `free', not `XFREE', for pointers that cannot
19848 2001-12-05 Akim Demaille <akim@epita.fr>
19850 * src/nullable.c (set_nullable): Deobfuscate the handling of
19852 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19854 2001-12-05 Akim Demaille <akim@epita.fr>
19856 * src/gram.c, src/gram.h (ritem_print): New.
19857 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19858 (This useless function was defined only to work around VMS linkers
19859 that can't handle compilation units with variables only).
19860 * src/reduce.c (dump_grammar): Use it to trace the construction of
19863 2001-12-04 Paul Eggert <eggert@twinsun.com>
19865 * src/bison.simple (union yyalloc): Change member names
19866 to be the same as the stack names.
19867 (yyparse): yyptr is now union yyalloc *, not char *.
19868 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19869 and may generate better code on some machines.
19870 (yystpcpy): Use prototype if __STDC__ is defined, not just
19871 if __cplusplus is defined.
19873 2001-11-30 Akim Demaille <akim@epita.fr>
19875 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19876 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
19877 Gettext doesn't compile cleanly, and dies with -Werror.
19878 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
19879 Include WARNING_CFLAGS here.
19880 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
19881 before being defined.

19885 * lib/quotearg.h (quotearg_n, quotearg_n_style):
19886 First arg is int, not unsigned.
19887 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
19888 (SIZE_MAX, UINT_MAX): New macros.
19889 (quotearg_n_options): Abort if N is negative.
19890 Avoid overflow check on hosts where size_t is 64 bits and int
19891 is 32 bits, as overflow is impossible there.
19892 Fix off-by-one typo that caused unnecessary reallocation.
19894 2001-11-29 Paul Eggert <eggert@twinsun.com>
19896 Name space cleanup in generated parser.
19898 * doc/bison.texinfo (Bison Parser): Discuss system headers
19899 and their effect on the user name space.
19901 * src/bison.simple:
19902 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19903 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19904 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19906 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
19907 on user names when possible.
19909 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
19910 Simplify test for whather <alloca.h> exists.
19912 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
19914 (<stdio.h>): Include if YYDEBUG.
19916 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
19917 ! defined (yyoverflow) && ! defined (yymemcpy).
19919 (yymemcpy, yyparse): Rename local variables as needed so that
19920 they all begin with 'yy'.
19922 (yystrlen, yystpcpy): New functions.
19924 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
19927 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
19928 instead of relying on string.h functions. Use YYSTACK_ALLOC
19929 and YYSTACK_FREE instead of malloc and free.
19931 2001-11-30 Akim Demaille <akim@epita.fr>
19933 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
19934 before their first uses.

19944 if body instead of `;' to pacify GCC's warnings.
19946 2001-11-30 Akim Demaille <akim@epita.fr>
19948 Instead of mapping the LHS of unused rules to -1, keep the LHS
19949 valid, but flag the rules as invalid.
19951 * src/gram.h (rule_t): `useful' is a new member.
19952 * src/print.c (print_grammar): Adjust.
19953 * src/derives.c (set_derives): Likewise.
19954 * src/reader.c (packgram, reduce_output): Likewise.
19955 * src/reduce.c (reduce_grammar_tables): Likewise.
19956 * tests/reduce.at (Underivable Rules, Useless Rules): New.

19982 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
19983 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
19985 (union yyalloc): New type.
19986 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
19987 an arbitrary restriction on hosts where size_t is wider than int.
19989 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19990 a parser stack overflow. Allocate just one block of memory for all
19991 three stacks, instead of allocating three blocks; this typically is
19992 faster and reduces fragmentation.
19994 Do not limit the number of items in the stack to a value that fits
19995 in 'int', as this is an arbitrary limit on hosts with 64-bit
19996 size_t and 32-bit int.
19998 2001-11-29 Marc Autret <autret_m@epita.fr>
20000 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

20051 2001-11-28 Akim Demaille <akim@epita.fr>
20053 * src/closure.c (closure): Instead of looping over word in array
20054 then bits in words, loop over bits in array.
20056 2001-11-28 Akim Demaille <akim@epita.fr>
20058 * src/closure.c (closure): No longer optimize the special case
20059 where all the bits of `ruleset[r]' are set to 0, to make the code
20062 2001-11-28 Akim Demaille <akim@epita.fr>
20064 * src/closure.c (closure): `r' and `c' are new variables, used to

20083 2001-11-27 Paul Eggert <eggert@twinsun.com>
20085 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

21807 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
21808 New, from fileutils 4.0.37.
21809 * configure.in: Require Autoconf 2.49c. I took some time before
21810 making this decision. This is the only way out for portability
21811 issues in Bison, it would mean way too much duplicate effort to
21812 import in Bison features implemented in 2.49c since 2.13.

21832 * src/lex.h: Rename all the tokens:
21833 s/\bENDFILE\b/tok_eof/g;
21834 s/\bIDENTIFIER\b/tok_identifier/g;
21836 Let them be enums, not #define, to ease debugging.

21855 * src/files.c (open_files): Don't call `compute_base_names', don't

21860 introduces a guaranteed SEGV for semantic parsers.
21861 * doc/bison.texinfo: Document them.
21862 * tests/suite.at: Exercise these %options.
21864 2000-12-20 Akim Demaille <akim@epita.fr>

22081 (output_files): this.
22082 Use `obstack_save'.
22083 * src/main.c (main): Don't use `atexit' to register `done', since
22084 it no longer has to remove tmp files, just call `output_files'
22085 when there are no errors.

22208 * bison.s1 (yyparse): Assign the default value
22209 unconditionally, to avoid a GCC warning and make the parser a
22212 2000-10-02 Akim Demaille <akim@epita.fr>
22214 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
22217 2000-10-02 Akim Demaille <akim@epita.fr>
22219 * src/derives.c, src/print.c, src/reduce.c: To ease the
22220 translation, move some `\n' out of the translated strings.
22222 2000-10-02 Akim Demaille <akim@epita.fr>
22224 The location tracking mechanism is precious for parse error
22225 messages. Nevertheless, it is enabled only when `@n' is used in
22226 the grammar, which is a different issue (you can use it in error
22227 message, but not in the grammar per se). Therefore, there should
22228 be another means to enable it.
22230 * src/getargs.c (getargs): Support `--locations'.
22231 (usage): Report it.
22232 * src/getargs.h (locationsflag): Export it.
22233 * src/lex.c (percent_table): Support `%locations'.
22234 * src/reader.c (yylsp_needed): Remove this variable, now replaced
22235 with `locationsflag'.
22236 * doc/bison.texinfo: Document `--locations' and `%locations'.
22238 * tests/calc.m4: Test it.
22240 For regularity of the names, replace each
22241 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
22242 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
22243 In addition replace each `flag' with `_flag'.
22245 2000-10-02 Akim Demaille <akim@epita.fr>
22247 Also test parse error messages, including with YYERROR_VERBOSE.
22249 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
22251 Use it to check the computations.
22252 Use it to check `nonassoc' is honored.
22253 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
22254 `--yyerror-verbose'.
22255 (_AT_CHECK_CALC): Adjust to this option.
22256 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
22258 2000-10-02 Akim Demaille <akim@epita.fr>
22260 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22261 the latter demonstrates a flaw in the handling of non debugging
22262 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22263 was used in order to simplify:
22279 unfortunately this leads to a CPP conflict when
22280 `--name-prefix=foo' is used since it produces `#define yydebug
22283 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
22284 (YYDPRINTF): New macro.
22286 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
22288 Also test `--verbose', `--defines' and `--name-prefix'.
22290 2000-10-02 Akim Demaille <akim@epita.fr>
22292 Improve the readability of the produced parsers.
22294 * src/bison.s1: Formatting changes.
22295 Improve the comment related to the `$' mark.
22296 (yydefault): Don't fall through to `yyresume': `goto' there.
22297 * src/output.c (output_parser): When the `$' is met, skip the end
22299 New variable, `number_of_dollar_signs', to check there's exactly
22300 one `$' in the parser skeleton.
22302 2000-10-02 Akim Demaille <akim@epita.fr>
22304 * lib/xstrdup.c: New file, from the fileutils.
22305 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
22306 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
22307 instead of strlen + xmalloc + strcpy.
22308 * src/symtab.c (copys): Remove, use xstrdup instead.
22310 2000-10-02 Akim Demaille <akim@epita.fr>
22312 * src/gram.h (associativity): New enum type which replaces the
22313 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
22314 `right_assoc', `left_assoc' and `non_assoc'.
22315 Adjust all dependencies.
22316 * src/reader.c: Formatting changes.
22317 (LTYPESTR): Don't define it, use it as a literal in
22318 `reader_output_yylsp'.
22319 * src/symtab.h (symbol_class): New enum type which replaces the
22320 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
22321 `sunknown', `stoken and `snterm'.
22323 2000-10-02 Akim Demaille <akim@epita.fr>
22325 * src/getargs.c (fixed_outfiles): Rename as...
22326 (yaccflag): for consistency and accuracy.
22327 Adjust dependencies.
22329 2000-10-02 Akim Demaille <akim@epita.fr>
22331 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22332 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22333 difficult and introduced a lot of core dump. It turns out that
22334 Bison used an implementation of `xmalloc' based on `calloc', and
22335 at various places it does depend upon the initialization to 0. I
22336 have not tried to isolate the pertinent places, and all the former
22337 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
22338 someone should address this issue.
22340 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
22341 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
22343 Adjust dependencies.
22344 * src/warshall.h: New file.
22347 2000-10-02 Akim Demaille <akim@epita.fr>
22349 Various anti-`extern in *.c' changes.
22351 * src/system.h: Include `assert.h'.
22353 2000-10-02 Akim Demaille <akim@epita.fr>
22355 * src/state.h (nstates, final_state, first_state, first_shift)
22356 (first_reduction): Move their exportation from here...
22357 * src/LR0.h: to here.
22358 Adjust dependencies.
22359 * src/getargs.c (statisticsflag): New variable.
22360 Add support for `--statistics'.
22361 Adjust dependencies.
22363 Remove a lot of now useless `extern' statements in most files.

22367 * src/LR0.h: New file.
22370 2000-10-02 Akim Demaille <akim@epita.fr>

22396 * src/reduce.h: New file.
22397 Propagate its inclusion.
22398 * src/reduce.c: Topological sort and other formatting changes.
22399 (bool, TRUE, FALSE): Move their definition to...
22400 * src/system.h: here.
22402 2000-10-02 Akim Demaille <akim@epita.fr>
22404 * src/files.c: Formatting changes.
22405 (tryopen, tryclose, openfiles): Rename as...
22406 (xfopen, xfclose, open_files): this.

22431 * src/lalr.c: Formatting changes, topological sorting etc.
22433 2000-10-02 Akim Demaille <akim@epita.fr>
22435 * src/output.c (token_actions): Introduce a temporary array,
22436 YYDEFACT, that makes it possible for this function to use
22437 output_short_table.
22439 2000-10-02 Akim Demaille <akim@epita.fr>
22441 `user_toknums' is output as a `short[]' in `output.c', while it is
22442 defined as a `int[]' in `reader.c'. For consistency with the
22443 other output tables, `user_toknums' is now defined as a table of

22459 order to get rid of the `static' prototypes.
22460 No longer use `register'.

22462 Propagate its inclusion in files explicitly prototyping functions
22465 2000-09-21 Akim Demaille <akim@epita.fr>

22486 Don't define PARAMS.
22487 * src/system.h: Define PARAMS.
22488 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
22489 purpose of config.h. system.h must not try to fix wrong
22490 definitions in config.h.

22706 2000-03-17 Akim Demaille <akim@epita.fr>
22708 Change the handling of @s so that they behave exactly like $s.
22709 There is now a pseudo variable @$ (readble and writable), location
22710 of the lhs of the rule (by default ranging from the location of
22711 the first symbol of the rhs, to the location of the last symbol,
22712 or, if the rhs is empty, YYLLOC).
22714 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
22716 (yyparse): When providing a default semantic action, provide a
22717 default location action.
22718 (after the $): No longer change `*YYLSP', just stack YYLOC the
22719 same way you stack YYVAL.
22720 * src/reader.c (read_declarations): Use warns.
22721 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
22722 (copy_action, case '@'): Likewise.

22744 2000-03-16 Akim Demaille <akim@epita.fr>
22746 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to

23418 (print_notices): Remove final `.' from error message.
23420 * src/reader.c (reader_output_yylsp):
23422 (readgram): Use `#if 0' around code that accepted %command
23423 inside grammar rules: The documentation doesn't allow it,
23424 and it will fail since the %command processors scan for the next %.
23425 (parse_token_decl): Extended the %token
23426 declaration to allow a multi-character symbol as an alias.
23427 (parse_thong_decl): New function.
23428 (read_declarations): Added %thong declarations.
23429 (read_declarations): Handle NOOP to deal with allowing
23430 % declarations as another means to specify the flags.
23431 (readgram): Allow %prec prior to semantics embedded in a rule.
23432 (skip_to_char, read_declarations, copy_definition)
23433 (parse_token_decl, parse_start_decl, parse_type_decl)
23434 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
23435 (get_type_name, copy_guard, copy_action, readgram)
23436 (get_type, packsymbols): Revised most error messages.
23437 Changed `fatal' to `warnxxx' to avoid aborting for error.
23438 Revised and use multiple warnxxx functions to avoid using VARARGS1.
23439 (read_declarations): Improve the error message for
23440 an invalid character. Do not abort.
23441 (read_declarations, copy_guard, copy_action): Use
23442 printable_version to avoid unprintable characters in printed output.
23443 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
23444 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
23445 Allow the type of a non-terminal can be given
23446 more than once, as long as all specifications give the same type.
23449 (output_headers, output_trailers, output, output_gram)
23450 (output_rule_data): Implement noparserflag variable.
23451 Implement toknumflag variable.
23452 (output): Call reader_output_yylsp to output LTYPESTR.
23454 * src/main.c (main):
23455 If reader sees an error, don't process the grammar.
23456 (fatals): Updated to not use VARARGS1.
23457 (printable_version, int_to_string, warn, warni, warns, warnss)
23458 (warnsss): New error reporting functions. Avoid abort for error.
23461 Added THONG and NOOP for alias processing.
23462 Added SETOPT for the new code that allows setting options with %flags.
23465 Include getopt.h. Add some extern decls.
23466 (safegetc): New function to deal with EOF gracefully.
23467 (literalchar); new function to deal with reading \ escapes.
23468 (lex): Use literalchar.
23469 (lex): Implemented "..." tokens.
23470 (literalchar, lex, parse_percent_token): Made tokenbuffer
23471 always contain the token. This includes growing the token
23472 buffer while reading an integer.
23473 (parse_percent_token): Replaced if-else statement with percent_table.
23474 (parse_percent_token): Added % declarations as another
23475 way to specify the flags -n, -l, and -r. Also added hooks for
23476 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
23477 major changes to files.c.
23478 (lex) Retain in the incoming stream a character following
23480 (skip_white_space, lex): Revised most error messages
23481 and changed fatal to warn to avoid aborting.
23482 (percent_table): Added %thong declarations.
23484 * src/gram.h: Comment changes.
23486 * src/files.c (openfiles, open_extra_files, done):
