535 * src/local.mk (BISON): New.
538 2009-04-06 Akim Demaille <demaille@gostai.com>
540 parser: handle %locations as %define locations.
541 * src/getargs.h, src/getargs.c (locations_flag): Remove.
542 * src/getargs.c, src/scan-code.l: Use muscle_percent_define_ensure
543 to set "locations" to true.
544 * src/output.c (prepare): Don't output "locations".
545 * src/scan-gram.l (%locations): Handle it as a %<flag>.
546 * src/parse-gram.y: It's no longer a token.

549 b4_percent_define_if_define.
550 * data/c.m4, data/glr.cc: Adjust.
552 2009-04-06 Akim Demaille <demaille@gostai.com>

557 2009-04-06 Akim Demaille <demaille@gostai.com>
559 muscle: factor the handling of obsolete of obsolete directives.
560 Suggested by Joel E. Denny.
562 * src/muscle_tab.h, src/muscle_tab.c (muscle_percent_define_ensure):
563 New, extracted from...
564 * src/parse-gram.y (prologue_declaration: pure-parser): here.
566 (prologue_declaration: "%<flag>"): Use
567 muscle_percent_define_ensure.
568 (%error-verbose, %pure-parser): No longer tokens.
569 * src/scan-gram.l (pure-parser): Return as a %<flag>.
571 2009-04-06 Joel E. Denny <jdenny@ces.clemson.edu>
573 Fix options documentation.
574 * build-aux/cross-options.pl: As in --help output, write optional
575 arguments as [=ARG] not =[ARG].
576 * doc/bison.texinfo (Bison Options): Add -W/--warnings argument.
578 2009-04-04 Joel E. Denny <jdenny@ces.clemson.edu>
580 Replace BISON_PROG_GNU_M4 with Autoconf's AC_PROG_GNU_M4.
581 If the first m4 in $PATH is wrong, it keeps looking. Moreover, its
582 requirements for a correct m4 are stricter.
583 * m4/m4.m4: Make it a symbolic link to submodules/autoconf/m4/m4.m4.
584 * configure.ac: Update to use AC_PROG_GNU_M4.
585 Reported by Eric Blake.
587 2009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>

598 2009-04-03 Akim Demaille <demaille@gostai.com>
600 Factor %FLAG at scan level.
601 * src/parse-gram.y (PERCENT_DEBUG, PERCENT_ERROR_VERBOSE): Token
602 definitions and associated rules, replaced by....
603 (PERCENT_FLAG): this new token type, and rule.
604 * src/scan-gram.l (RETURN_PERCENT_FLAG): New.
605 Use it for %debug and %error-verbose.

622 2009-04-03 Akim Demaille <demaille@gostai.com>
624 Treat %error-verbose as %define error_verbose.
625 This allows to pass -Derror_verbose on the command line. Better
626 yet, it allows to pass -Derror_verbose=$(ERROR_VERBOSE), with
627 ERROR_VERBOSE being defined as false or true.
628 * data/bison.m4 (b4_percent_define_if_define): Instead of relying
629 on b4_percent_define_ifdef, for does not check the defined value,
630 but only whether the symbol is defined, rely on
631 b4_percent_define_flag_if, so that a value of "false" is processed
633 If not defined, define the flag to "false".
634 (b4_error_verbose_if): New.
635 * data/glr.c, data/lalr1.cc, data/yacc.c: Use it instead of
636 b4_error_verbose_flag.
637 * src/getargs.h, src/getargs.c (error_verbose_flag): Remove.
638 * src/output.c (prepare): Don't output it.
639 * src/parse-gram.y (%error-verbose): Treat as %define error_verbose.
641 2009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>

644 Reported by Akim Demaille at
645 <http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html>
646 and discussed again starting at
647 <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
648 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
649 because location information is bogus.
650 Use angle brackets to delimit fake file name because square brackets
651 look like underexpanded m4. Choose a better fake file name.
652 Use negative line numbers.
653 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
654 * src/location.c (location_print): If line for a boundary is negative,
655 only print that boundary's file name.
656 * src/location.h: Document that.
657 * tests/skeletons.at (%define Boolean variables: invalid skeleton
658 defaults): Update output.
660 2009-04-03 Joel E. Denny <jdenny@ces.clemson.edu>
662 Pacify ./configure --enable-gcc-warnings.
663 * Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS) because many files
664 in lib won't compile with it.
665 * src/local.mk (src_bison_CFLAGS): Use $(WERROR_CFLAGS) here only.
667 2009-03-31 Akim Demaille <demaille@gostai.com>
669 bootstrap: --help to stdout.
670 * bootstrap (usage): Don't send --help to stderr.
671 Use a here doc instead of a long string.

695 lalr1.cc: avoid GCC 4.3 warnings.
696 GCC 4.3 now warns about "a || b && c" and asks for explicit
698 Reported by Alexandre Duret-Lutz.
699 * data/location.cc: Update copyright years.
700 (Position::operator==): Use parens to make precedence explicit.
701 Compare lines and columns first, as they are more likely to be
702 different, and they are faster to compare.
704 2009-03-26 Akim Demaille <demaille@gostai.com>
707 * gnulib: Update to latest.
708 * src/local.mk (AM_CFLAGS): Move to...

723 2009-03-02 Akim Demaille <demaille@gostai.com>
725 Use locations in the variant example.
726 Yes, this obfuscates the point of this example, variants only.
727 But glr.cc cannot work (yet?) without locations. This change
728 makes it easier to use this example with glr.cc.
730 * examples/variant.yy (assert): %define it.
731 (locations): Request them.
732 (yylex): Bind the location to the stage.

747 * data/lalr1.cc: No longer invoke b4_symbol_constructor_define and
748 b4_symbol_constructor_declare, as it is now done by
749 b4_public_types_define and b4_public_types_declare.

956 Fix portability issue in the test suite.
957 * tests/local.at (AT_MATCHES_CHECK): New.

993 2008-12-07 Di-an Jan <dianj@freeshell.org>
995 Implement the FIXME that ends an user action with a semicolon
996 if it seems necessary.
997 * src/scan-code.l (flex rules section): Flag cpp directive from
998 any `#' to the first unescaped end-of-line. Semicolon is not
999 needed after `;', `{', '}', or cpp directives and is needed after
1000 any other token (whitespaces and comments have no effect).

1003 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
1004 to make user actions complete statements.
1005 Adjust column numbers in error messages.

1066 2008-12-01 Akim Demaille <demaille@gostai.com>
1068 Use the symbol properties to output the printer/destructor for lalr1.cc.
1069 Instead of defining complex list of tuples to define various
1070 properties of the symbols, we now prefer to define symbols as
1071 "structs" in m4: using the symbol key (its number), and the
1072 property name, b4_symbol gives it value. Use this to handle
1073 destructors and printers.
1075 * src/output.c (CODE_PROP): New.
1076 (prepare_symbol_definitions): Use it to define the printer and
1077 destructor related attributes of the symbols.
1078 * data/lalr1.cc (b4_symbol_actions): Rename as...
1079 (b4_symbol_action): this.
1080 Use b4_symbol instead of 6 arguments.
1081 (b4_symbol_printer, b4_symbol_destructor): New.

1096 2008-11-26 Akim Demaille <demaille@gostai.com>
1098 Convert lib/Makefile.am into lib/local.mk.
1099 The real problem is rather gnulib.mk, which itself is extracted
1100 from a Makefile.am that gnulib expects to the "recursive". The
1101 tool prefix-gnulib-mk converts such a gnulib.mk to be
1102 non-recursive. Also, some AC_SUBST variables need to be adjusted.
1104 * etc/prefix-gnulib-mk: New.
1105 * bootstrap (slurp): Use it to convert further gnulib.mk.
1106 No longer try to avoid re-creation of lib/gnulib.mk as the changes

1109 * lib/local.mk: this.

1172 * tests/regression.at (Web2c Actions): Adjust the expected output,
1173 the order of the tables changed.
1175 2008-11-26 Akim Demaille <demaille@gostai.com>
1177 Get rid of (yy)rhs and (yy)prhs.
1178 These tables are no longer needed in the parsers, and they don't seem to
1179 be useful. They are not documented either.
1181 * src/output.c (prepare_rules): Get rid of rhs and prhs.
1182 Adjust the computation of (yy)r2.
1184 2008-11-26 Akim Demaille <demaille@gostai.com>
1186 Rule length is unsigned.
1187 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
1189 2008-11-26 Akim Demaille <demaille@gostai.com>
1191 Get rid of lalr1-split.cc.
1192 It was no longer maintainer.
1194 * data/lalr1-split.cc: Remove.
1195 * etc/bench.pl.in (bench_fusion_parser): Remove.
1198 2008-11-26 Akim Demaille <demaille@gostai.com>

1207 Get rid of yyrhs and yyprhs in glr.c.
1208 * data/glr.c (yyrhs, yyprhs): Remove.

1214 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
1215 as an Autotest keyword.
1217 2008-11-25 Akim Demaille <demaille@gostai.com>
1219 Prefer TESTSUITE_FLAGS.
1220 TESTSUITEFLAGS is barely readable.
1222 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
1223 for backward compatibility.
1224 Use the former instead of the latter.

1236 2008-11-25 Akim Demaille <demaille@gostai.com>
1238 Get rid of yyrhs and yyprhs in yacc.c.
1239 They were used to get the symbol types, given a rule number, when
1240 displaying the top of the stack before a reduction. But the
1241 symbol type is available from the state stack. This has two be
1242 benefits: two tables less in the parser (making it smaller), and a
1243 more consistent use of the three stacks which will help to fuse
1246 * data/yacc.c (yyprhs, yyrhs): Remove.
1247 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
1248 (yy_reduce_print): Take yyssp as argument.
1249 Use it, together with yystos, to get the symbol type.
1250 * tests/regression.at (Web2c Report): Remove these tables from the
1253 2008-11-25 Akim Demaille <demaille@gostai.com>
1256 The point is to factor the generation of the tables across skeletons.
1257 This is language dependant.
1259 * data/c.m4 (b4_comment_): New.
1260 Should be usable to define how to generate tables independently of
1262 (b4_c_comment): New.
1263 (b4_comment): Bounce to b4_c_comment.
1264 Now support $2 = [PREFIX] for indentation.
1265 * data/lalr1.cc (b4_table_declare): Don't output a comment if
1266 there is no comment.
1267 Indent it properly when there is one.
1268 Output the ending semicolon.
1269 (b4_table_define): Space changes.
1270 Output the ending semicolon.
1271 (b4_tables_map): New.
1272 Use it twice instead of declaring and defining the (integral)

1280 (b4_table_define): Declare a third arg to match b4_table_declare
1282 Move all the comments around invocations of b4_table_define into
1283 the invocations itselves.
1284 Move things around to have the order for declarations and

1437 2008-11-15 Akim Demaille <demaille@gostai.com>
1439 Support parametric types.
1441 There are two issues to handle: first scanning nested angle
1442 bracket pairs to support types such as std::pair< std::string,
1443 std::list<std::string> > >.
1445 Another issue is to address idiosyncracies of C++: do not glue two
1446 closing angle brackets together (otherwise it's operator>>), and
1447 avoid sticking blindly a TYPE to the opening <, as it can result
1448 in '<:' which is a digraph for '['.
1450 * src/scan-gram.l (brace_level): Rename as...
1453 Implement support for complex tags.
1456 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)

1467 This is not sufficient, but we test at least that the make_SYMBOL
1468 interface is not affected by token.prefix. A more general test
1469 will be implemented when the support of token.prefix is generalized

1546 Move sc_tight_scope into maint.mk.
1547 It does not work, and I don't know how it was supposed to work: it

1621 * build-aux/Makefile.am: Rename as...
1622 * build-aux/local.mk: this.
1624 * Makefile.am, configure.ac: Adjust.
1626 2008-11-15 Akim Demaille <demaille@gostai.com>
1628 Provide convenience constructors for locations and positions.
1629 * data/location.cc (position::position): Accept file, line and
1630 column as arguments with default values.
1631 Always qualify initial line and column literals as unsigned.
1632 (location::location): Provide convenience constructors.
1634 2008-11-15 Akim Demaille <demaille@gostai.com>
1636 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
1638 Using template buys us nothing, and makes it uselessly complex to
1639 construct a symbol. Besides, it could not be generalized to other
1640 languages, while make_FOO would work in C/Java etc.
1642 * data/lalr1.cc (b4_symbol_): New.
1643 (b4_symbol): Use it.
1644 (b4_symbol_constructor_declaration_)
1645 (b4_symbol_constructor_definition_): Instead of generating
1646 specializations of an overloaded template function, just generate
1647 several functions whose names are forged from the token names
1648 without the token.prefix.
1649 (b4_symbol_constructor_declarations): Generate them for all the
1650 symbols, not just by class of symbol type, now that instead of
1651 specializing a function template by the token, we generate a
1652 function named after the token.
1653 (b4_symbol_constructor_specialization_)
1654 (b4_symbol_constructor_specializations): Remove.
1655 * etc/bench.pl.in: Adjust to this new API.
1657 2008-11-13 Akim Demaille <demaille@gostai.com>
1659 %define token.prefix.
1660 Provide a means to add a prefix to the name of the tokens as
1661 output in the generated files. Because of name clashes, it is
1662 good to have such a prefix such as TOK_ that protects from names
1663 such as EOF, FILE etc. But it clutters the grammar itself.
1665 * data/bison.m4 (token.prefix): Empty by default.
1666 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
1667 * data/lalr1.cc (b4_symbol): Ditto.
1669 2008-11-13 Akim Demaille <demaille@gostai.com>
1671 Compute at M4 time some of the subtractions.
1672 * data/lalr1.cc (b4_subtract): New.
1673 (b4_rhs_data): Use it.
1675 2008-11-13 Akim Demaille <demaille@gostai.com>
1678 This allows the user to get the type of a token returned by yylex.
1680 * data/lalr1.cc (symbol::token): New.
1681 (yytoknum_): Define when %define lex_symbol, independently of
1683 (yytoken_number_): Move into...
1684 (symbol::token): here, since that's the only use.
1685 The other one is YYPRINT which was not officially supported
1686 by lalr1.cc, and anyway it did not work since YYPRINT uses this
1687 array under a different name (yytoknum).
1689 2008-11-13 Akim Demaille <demaille@gostai.com>
1692 * TODO (YYERRCODE): Mention the case of $undef.
1694 2008-11-13 Akim Demaille <demaille@gostai.com>
1697 * TODO (YYPRINT): New.
1699 2008-11-13 Akim Demaille <demaille@gostai.com>
1702 * data/lalr1.cc, data/yacc.c: Fix the description of the
1703 yytranslate and yytoknum tables.
1705 2008-11-13 Akim Demaille <demaille@gostai.com>
1707 Define make_symbol in the header.
1708 To reach good performances these functions should be inlined (yet
1709 this is to measure precisely). To this end they must be available
1712 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
1713 location_type with the class name.
1714 Since will now be output in the header, declare "inline".
1715 No longer use b4_symbol_constructor_specializations, but
1716 b4_symbol_constructor_definitions in the header.
1717 Don't call it in the *.cc file.
1719 2008-11-13 Akim Demaille <demaille@gostai.com>
1721 Define yytranslate in the header for lex_symbol.
1722 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
1723 into the header file when using %define lex_symbol.
1724 (yytranslate_): Declare inline.
1726 2008-11-13 Akim Demaille <demaille@gostai.com>
1728 Define the constructors of symbol_type in
1729 b4_symbol_constructor_definitions.
1730 The constructors are called by the make_symbol functions, which a
1731 forthcoming patch will move elsewhere. Hence the interest of
1732 putting them together.
1734 The stack_symbol_type does not need to be moved, it is used only
1737 * data/lalr1.cc: Move symbol_type and symbol_base_type
1738 constructors into...
1739 (b4_symbol_constructor_definitions): here.
1742 2008-11-13 Akim Demaille <demaille@gostai.com>
1744 Make it easier to move the definition of yytranslate_.
1745 Forthcoming changes will make it possible to use yytranslate_
1746 from outside the parser implementation file.
1748 * data/lalr1.cc (b4_yytranslate_definition): New.
1751 2008-11-13 Akim Demaille <demaille@gostai.com>
1753 Remove useless class specification.
1754 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
1755 to refer to the class name to use a type defined by the class for
1756 arguments of member functions.
1758 2008-11-13 Akim Demaille <demaille@gostai.com>
1760 Finer input type for yytranslate.
1761 This patch is debatable: the tradition expects yylex to return an int
1762 which happens to correspond to token_number (which is an enum). This
1763 allows for instance to return characters (such as '*' etc.). But this
1764 goes against the stronger typing I am trying to have with the new
1765 lex interface which return a symbol_type. So in this case, feed
1766 yytranslate_ with a token_type.
1768 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
1769 expect a token_type.
1771 2008-11-13 Akim Demaille <demaille@gostai.com>
1773 Honor lex-params in %define lex_symbol mode.
1774 * data/lalr1.cc: Use b4_lex_param.
1776 2008-11-13 Akim Demaille <demaille@gostai.com>
1779 * src/output.c (symbol_definitions_output): Rename symbol
1780 attributes type_name and has_type_name as type and has_type.
1781 * data/lalr1.cc: Adjust uses.
1783 2008-11-13 Akim Demaille <demaille@gostai.com>
1785 Use b4_type_names for the union type.
1786 The union used to compute the size of the variant used to iterate
1787 over the type of all the symbols, with a lot of redundancy. Now
1788 iterate over the lists of symbols having the same type-name.
1790 * data/lalr1.cc (b4_char_sizeof_): New.
1791 (b4_char_sizeof): Use it.
1792 Adjust to be called with a list of numbers instead of a single
1794 Adjust its caller for new-line issues.
1796 2008-11-13 Akim Demaille <demaille@gostai.com>
1798 Define the "identifier" of a symbol.
1799 Symbols may have several string representations, for instance if
1800 they have an alias. What I call its "id" is a string that can be
1801 used as an identifier. May not exist.
1803 Currently the symbols which have the "tag_is_id" flag set are
1804 those that don't have an alias. Look harder for the id.
1806 * src/output.c (is_identifier): Move to...
1807 * src/symtab.c (is_identifier): here.
1808 * src/symtab.h, src/symtab.c (symbol_id_get): New.
1809 * src/output.c (symbol_definitions_output): Use it to define "id"
1811 Remove the definition of "tag_is_id".
1812 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
1813 "tag_is_id" were used to produce code.
1814 We still use "tag" for documentation.
1816 2008-11-11 Akim Demaille <demaille@gostai.com>
1818 Locations are no longer required by lalr1.cc.
1819 * data/lalr1.cc (_b4_args, b4_args): New.
1820 Adjust all uses of locations to make them optional.
1821 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
1822 (AT_CHECK_NAMESPACE): Check the use of locations.
1823 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
1824 without locations with lalr1.cc.
1826 * tests/output.at: Check lalr1.cc with and without location
1828 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
1829 Don't use locations.
1831 2008-11-11 Akim Demaille <demaille@gostai.com>
1834 * tests/local.at (AT_FULL_COMPILE): New.
1835 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
1837 2008-11-11 Akim Demaille <demaille@gostai.com>
1839 Support parens in calc++.
1840 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
1841 * examples/calc++/test (run): Check the expected output.
1845 2008-11-11 Akim Demaille <demaille@gostai.com>
1847 Simplify lalr1.cc since %defines is mandatory.
1848 * data/lalr1.cc: Remove useless calls to b4_defines_if.
1850 2008-11-11 Akim Demaille <demaille@gostai.com>
1853 * TODO (yysyntax_error): New item.
1855 2008-11-11 Akim Demaille <demaille@gostai.com>
1858 * data/lalr1.cc: Use b4_error_verbose_if instead of #if
1861 2008-11-11 Akim Demaille <demaille@gostai.com>
1863 Support i18n of the parse error messages.
1864 * TODO (lalr1.cc/I18n): Remove.
1865 * data/lalr1.cc (yysyntax_error_): Support the translation of the
1866 error messages, as done in yacc.c.
1867 Stay within the yy* pseudo namespace.
1869 2008-11-11 Akim Demaille <demaille@gostai.com>
1872 * TODO (single stack, yysyntax_error): New.
1874 2008-11-11 Akim Demaille <demaille@gostai.com>
1876 Make it possible to return a symbol_type from yylex.
1877 * data/lalr1.cc (b4_lex_symbol_if): New.
1878 (parse): When lex_symbol is defined, expected yylex to return the
1880 * etc/bench.pl.in (generate_grammar_list): Extend to support this
1882 (bench_variant_parser): Exercise it.
1884 2008-11-11 Akim Demaille <demaille@gostai.com>
1886 Remove useless bench case.
1887 * etc/bench.pl.in (bench_variant_parser): VARIANT_DESTROY is
1890 2008-11-11 Akim Demaille <demaille@gostai.com>
1892 Improve display of directives.
1893 * etc/bench.pl.in (parse_term): Don't add useless eol.
1895 2008-11-11 Akim Demaille <demaille@gostai.com>
1897 Use string_cast in the bench.
1898 * etc/bench.pl.in (generate_grammar_list): Define and use
1901 2008-11-11 Akim Demaille <demaille@gostai.com>
1903 Replace yychar with a Boolean.
1904 * data/lalr1.cc (parse::yychar): Replace by...
1905 (parse::yyempty): this.
1907 2008-11-11 Akim Demaille <demaille@gostai.com>
1912 2008-11-11 Akim Demaille <demaille@gostai.com>
1914 Let yytranslate handle the eof case.
1915 * data/lalr1.cc (yytranslate_): Handle the EOF case.
1917 No longer expect yychar to be equal to yyeof_, rather, test the
1918 lookahead's (translated) kind.
1920 2008-11-11 Akim Demaille <demaille@gostai.com>
1922 yychar cannot be empty in yyerrlab.
1923 * TODO (yychar == yyempty_): New.
1924 * data/lalr1.cc: Remove the handling of this case.
1925 This eases forthcoming changes related to yychar and yytranslate.
1927 2008-11-11 Akim Demaille <demaille@gostai.com>
1929 Bench: syntactic sugar for %define/#define.
1930 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
1931 (&bench_push_parser, bench_variant_parser): Use this feature.
1935 2008-11-11 Akim Demaille <demaille@gostai.com>
1937 Less memory pressure on the "list" bench.
1938 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
1939 the values, to limit memory pressure.
1941 2008-11-11 Akim Demaille <demaille@gostai.com>
1943 Introduce make_symbol.
1944 make_symbol provides a means to construct a full symbol (kind,
1945 value, location) in a single shot. It is meant to be a Symbol
1946 constructor, parameterized by the symbol kind so that overloading
1947 would prevent incorrect kind/value pairs. Unfortunately
1948 parameterized constructors do not work well in C++ (unless the
1949 parameter also appears as an argument, which is not acceptable),
1950 hence the use of a function instead of a constructor.
1952 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1953 (b4_symbol_constructor_declarations)
1954 (b4_symbol_constructor_specialization_)
1955 (b4_symbol_constructor_specializations)
1956 (b4_symbol_constructor_definition_)
1957 (b4_symbol_constructor_definitions): New.
1958 Use them where appropriate to generate declaration, declaration of
1959 the specializations, and implementations of the templated
1960 overloaded function "make_symbol".
1961 (variant::variant): Always define a default ctor.
1962 Also provide a copy ctor.
1963 (symbol_base_type, symbol_type): New ctor overloads for value-less
1965 (symbol_type): Now public, so that functions such as yylex can use
1968 2008-11-11 Akim Demaille <demaille@gostai.com>
1970 Inform m4 whether a tag is a valid id.
1971 * src/output.c (is_identifier): New.
1972 (symbol_definitions_output): Use it to define tag_is_id.
1973 But maybe this should be done at m4 level?
1975 2008-11-11 Akim Demaille <demaille@gostai.com>
1977 Test 214 was failing: it greps with a pattern containing [ ]*
1978 which obviously meant to catch spaces and tabs, but contained only
1979 spaces. Tabulations in sources are a nuisance, so to simplify the
1980 matter, get rid of all the tabulations in the Java sources. The
1981 other skeletons will be treated equally later.
1983 * data/java.m4, data/lalr1.java: Untabify.
1984 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1985 tabulations are no longer generated.
1987 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
1989 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
1990 * configure.ac: Adjust usage.
1991 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1992 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1993 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).
1995 2008-11-10 Di-an Jan <dianj@freeshell.org>
1997 Workaround Java's ``code too large'' problem for parser tables
1998 in most cases, by using one function per initialization.
1999 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
2000 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
2001 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_
2002 yyprhs_, yyrline_, yytranslate_table_): Use b4_integral_parser_table.

2009 * NEWS: Document them.
2011 General Java skeleton improvements.
2012 * configure.ac (gt_JAVACOMP): Request target of 1.4, which allows
2013 using gcj < 4.3 in the testsuite, according to comments in
2014 gnulib/m4/javacomp.m4.
2015 * data/java.m4 (stype, parser_class_name, lex_throws, throws,
2016 location_type, position_type): Remove extraneous brackets from
2017 b4_percent_define_default.
2018 (b4_lex_param, b4_parse_param): Remove extraneous brackets from
2019 m4_define and m4_define_default.
2020 * data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
2021 which marks the end of user code with appropriate syncline, like all
2022 the other skeletons.
2023 (b4_user_post_prologue): Add. Don't silently drop.
2025 (parse): Inline yylex.
2026 * doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
2027 (%{...%}): Fix typo of %code imports.
2028 * tests/java.at (AT_JAVA_COMPILE): Add "java" keyword.
2030 Support annotations on parser class with %define annotations.
2031 * data/lalr1.java (annotations): Add to parser class modifier.
2032 * doc/bison.texinfo (Java Parser Interface): Document
2033 %define annotations.

2044 about %error-verbose having no effect.
2045 (getErrorVerbose, setErrorVerbose): Document.
2047 Move constants for token names to Lexer interface.
2048 * data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.
2049 * data/java.m4 (b4_token_enum): Indent for move to Lexer interface.
2050 (parse): Qualify EOF to Lexer.EOF.
2051 * doc/bison.texinfo (Java Parser Interface): Move documentation of
2052 EOF and token names to Java Lexer Interface.
2053 * tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove Calc qualifier.
2055 Make yyerror public.
2056 * data/lalr1.java (Lexer.yyerror): Use longer parameter name.
2057 (yyerror): Change to public. Add Javadoc comments. Use longer
2058 parameter names. Make the body rather than the declarator
2059 conditional on %locations.
2060 * doc/bison.texinfo (yyerror): Document. Don't mark as protected.
2062 Allow user to add code to the constructor with %code init.

2090 including those that don't have a type-name.
2091 (symbol_definitions_output): Define "is_token" and
2093 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
2094 type-name, now that they are defined too in b4_type_names.
2096 2008-11-10 Akim Demaille <demaille@gostai.com>
2100 2008-11-10 Akim Demaille <demaille@gostai.com>
2102 Make parser::yytranslate static.
2103 Small speedup (1%) on the list grammar. And makes yytranslate_
2104 available in non member functions.

2111 Avoid trailing spaces.
2112 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
2113 * data/lalr1.cc: Don't indent before rule and symbol actions, as
2114 they can be empty, and anyway this incorrectly indents the first
2117 2008-11-10 Akim Demaille <demaille@gostai.com>
2121 2008-11-10 Akim Demaille <demaille@gostai.com>
2123 Use "enum" for integral constants.

2126 * data/lalr1.cc (yyeof_, yylast_, yynnts_, yyempty_, yyfinal_)
2127 (yterror_, yyerrcode_, yyntokens_): Define as members of an enum.

2165 Change the handling of the symbols in the skeletons.
2166 Before we were using tables which lines were the symbols and which
2167 columns were things like number, tag, type-name etc. It is was
2168 difficult to extend: each time a column was added, all the numbers had
2169 to be updated (you asked for colon $2, not for "tag"). Also, it was
2170 hard to filter these tables when only a subset of the symbols (say the
2171 tokens, or the nterms, or the tokens that have and external number
2172 *and* a type-name) was of interest.
2174 Now instead of monolithic tables, we define one macro per cell. For
2175 instance "b4_symbol(0, tag)" is a macro name which contents is
2176 self-decriptive. The macro "b4_symbol" provides easier access to
2179 * src/output.c (type_names_output): Remove.

2223 2008-11-10 Akim Demaille <demaille@gostai.com>
2225 Add %precedence support.
2226 Unfortunately it is not possible to reuse the %prec directive. This
2227 is because to please POSIX, we do not require to end the rules with a
2228 semicolon. As a result,
2232 is ambiguous: either a rule which precedence is that of baz, or a rule,
2233 and then a declaration of the precedence of the token baz.

2363 Rely on the state stack to display reduction traces.
2364 To display rhs symbols before a reduction, we used information
2365 about the rule reduced, which required the tables yyrhs and
2366 yyprhs. Now use rely only on the state stack to get the same

2495 Add "%define assert" to variants.
2496 This is used to help the user catch cases where some value gets
2497 ovewritten by a new one. This should not happen, as this will
2500 Unfortunately this uncovered a bug in the C++ parser itself: the
2501 lookahead value was not destroyed between two calls to yylex. For
2502 instance if the previous lookahead was a std::string, and then an int,
2503 then the value of the std::string was correctly taken (i.e., the
2504 lookahead was now an empty string), but std::string structure itself
2507 This is now done in variant::build(other&) (which is used to take the
2508 value of the lookahead): other is not only stolen from its value, it
2509 is also destroyed. This incurs a new performance penalty of a few
2510 percent, and union becomes faster again.
2512 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

2791 Fuse the three stacks into a single one.
2793 In order to make it easy to perform benchmarks to ensure that
2794 there are no performance loss, lalr1.cc is forked into
2795 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2798 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2799 exercized by the test suite, the user must install a symbolic link
2800 from lalr1.cc to it.
2802 Instead of having three stacks (state, value, location), use a
2803 stack of triples. This considerably simplifies the code (and it
2804 will be easier not to require locations as currently does the C++
2805 parser), and also gives a 10% speedup according to
2806 etc/bench (probably mainly since memory allocation is done once
2807 instead of three times).
2809 Another motivation is to make it easier to destruct properly
2810 semantic values: now that they are bound to their state (hence
2811 symbol type) it will be easier to call the appropriate destructor.
2813 These changes should probably benefit the C parser too.
2815 * data/lalr1.cc: Copy as...
2816 * data/lalr1-fusion.cc: this new file.
2817 (b4_rhs_value, b4_rhs_location): New definitions overriding those
2819 (state_stack_type, semantic_stack_type, location_stack_type)
2820 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
2821 (data_type, stack_type, yystack_): New.
2822 (YYLLOC_DEFAULT, yypush_): Adjust.
2823 (yyerror_range): Now based on data_type, not location_type.
2825 2008-11-03 Akim Demaille <demaille@gostai.com>
2827 Push the state, value, and location at the same time.
2828 This is needed to prepare a forthcoming patch that fuses the three
2831 * data/lalr1.cc (parser::yypush_): New.
2832 (parser::yynewstate): Change the semantics: instead of arriving to
2833 this label when value and location have been pushed, but yystate
2834 is to be pushed on the state stack, now the three of them must
2835 have been pushed before. yystate still must be the new state.
2836 This allows to use yypush_ everywhere instead of individual
2837 handling of the stacks.
2839 2008-11-03 Akim Demaille <demaille@gostai.com>
2841 Prefer references to pointers.
2842 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
2843 definition to use references instead of pointers.
2844 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
2845 Take the value and location as references.
2848 2008-11-03 Akim Demaille <demaille@gostai.com>
2850 stack::size instead of stack::height.
2851 * data/lalr1.cc (stack::height): Rename as...
2852 (stack::size): this.
2853 Fix the output type.
2856 2008-11-03 Akim Demaille <demaille@gostai.com>
2858 Use variants to support objects as semantic values.
2859 This patch was inspired by work by Michiel De Wilde. But he used
2860 Boost variants which (i) requires Boost on the user side, (ii) is
2861 slow, and (iii) has useless overhead (the parser knows the type of
2862 the semantic value there is no reason to duplicate this
2863 information as Boost.Variants do).
2865 This implementation reserves a buffer large enough to store the
2866 largest objects. yy::variant implements this buffer. It was
2867 implemented with Quentin Hocquet.
2869 * src/output.c (type_names_output): New.
2870 (output_skeleton): Invoke it.
2871 * data/c++.m4 (b4_variant_if): New.
2872 (b4_symbol_value): If needed, provide a definition for variants.
2873 * data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
2874 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
2875 (b4_char_sizeof, yy::variant): New.
2876 (parser::parse): If variants are requested, define
2877 parser::union_type, parser::variant, change the definition of
2878 semantic_type, construct $$ before running the user action instead
2879 of performing a default $$ = $1.
2880 * examples/variant.yy: New.
2881 Based on an example by Michiel De Wilde.
2883 2008-11-03 Akim Demaille <demaille@gostai.com>
2885 Parameterize the extraction of semantic values.
2886 To make future changes easier, no longer rely on ".TYPE" being the
2887 way to get a semantic value.
2889 * data/c.m4 (b4_symbol_value): New.
2891 * data/c++.m4, data/yacc.c: Use it.
2892 * data/glr.c: Use b4_symbol_value.
2896 2008-11-03 Akim Demaille <demaille@gostai.com>

3000 Always put auxiliary code files in the same dir as other output files.
3001 * src/files.c (compute_file_name_parts): When the user specifies
3002 --output but not --file-prefix, extract the directory prefix from the
3003 file prefix not from the grammar file name. This affects the location

3269 * NEWS (2.3b+): Rename to...
3270 (?.?): ... this because we're dropping the "+" version naming scheme,
3271 but, in general, we still can't be sure of our next release name.
3272 * bootstrap: Add a quick hack to remove from .gitignore the
3273 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
3274 entry. This should really be fixed in gnulib instead.
3275 * bootstrap.conf (gnulib_modules): Add gnumakefile.
3276 * configure.ac (AC_INIT): Set version name by invoking
3277 build-aux/git-version-gen.

3305 2008-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
3307 Fix some .gitignore and .cvsignore problems.
3308 * bootstrap (insert_sorted_if_absent): Replace all uses with...
3309 (insert_vc_ignore): ... this new function, which prepends `/' to all
3310 .gitignore entries before passing them to insert_sorted_if_absent.
3311 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
3312 .cvsignore files are maintained even though Bison developers run
3313 bootstrap while using Git.
3314 * .cvsignore (*.patch *.log log patches applied): Remove, apparently

3333 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
3334 the first argument because it may become position-dependent, and unset
3335 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
3336 Add comments explaining these issues in more detail.
3338 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

3400 Revert prior patch, by working around autoconf regression.
3401 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
3402 ("Output file name: ("): Uncomment test.
3403 ("Output file name: )"): Likewise.
3404 Based on an idea from Noah Misch.

3420 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
3422 Update to the current gnulib CVS repository, and fix trigraph handling
3424 * bootstrap: Update gnulib CVS repository URL.
3425 (symlink_to_dir): Encapsulate the code that guarantees the destination
3426 directory exists into...
3427 (check_dst_dir): ... this new function, and...
3428 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
3429 fail when copying files into lib/uniwidth/.
3430 * src/output.c (prepare_symbols): When writing yytname muscles, where
3431 symbol names will be encoded in C-string literals, tell quotearg to
3432 escape trigraphs. This used to be the default in gnulib.
3433 * tests/regression.at (Token definitions): Because of the change in
3434 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
3435 escapes trigraphs in symbol names. Thus, yytname no longer has
3436 trigraphs unnecessarily doubly escaped. Update test case output.
3437 Extend test case to be sure Bison's own error messages will no longer
3438 have trigraphs in symbol names unnecessarily escaped once.

3453 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
3454 consistency. Update the -g and -x entries now that they take
3455 arguments. Use brackets to indicate optional arguments.
3456 * src/getargs.c (usage): Explain the relationship between arguments of
3457 long and short options more completely. Document --defines and -d
3458 separately since the former takes an argument but, for POSIX Yacc, the
3460 (short_options): Let -W take an optional argument like --warnings.

3478 Fix the handling of $opt which resulted in all the argument to be
3479 considered as optional.
3481 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

3517 * data/yacc.c: Clean up whitespace in the output a little.
3518 (yypstate_allocated): Define for impure push parsers regardless of
3519 whether the pull interface is also requested.
3520 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
3521 check impure push parsers without the pull interface.
3523 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since

4160 * data/bison.m4 (b4_cat): New.
4161 (b4_error, b4_error_at): Use b4_cat to send error directives directly
4162 to stdout so they don't become arguments to other macros. Update
4163 comments and add examples.
4164 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
4166 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
4167 after printing the error directive so that M4 doesn't report subsequent
4168 problems that are induced by this problem.
4169 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
4170 instead of just in them. Recognize @\n in both places. Both expand to
4171 the empty string. Needed by b4_cat.
4172 * tests/skeletons.at (Complaining during macro argument expansion):
4174 (Fatal errors make M4 exit immediately): New test case.
4176 2007-10-04 Joel E. Denny <jdenny@ces.clemson.edu>
4178 Implement --print-datadir.
4179 * src/getargs.c (usage): Mention.
4180 (PRINT_DATADIR_OPTION): New anonymous enum member.
4181 (long_options): Add entry for it.
4182 (getargs): Add case for it calling compute_pkgdatadir.
4183 * src/output.c (output_skeleton): Encapsulate data directory
4184 computation from here...
4185 (prepare): ... and from here...
4186 (compute_pkgdatadir): ... into this new function.
4187 * src/output.h (compute_pkgdatadir): Prototype.
4189 2007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>
4191 * src/print-xml.c (escape_bufs): New static global variable
4193 (xml_escape_n): ... the static local variable buf here.
4194 (print_xml): Free memory for escape_bufs.
4195 * src/reduce.c (reduce_xml): XML-escape terminal symbol tags.
4197 2007-09-25 Joel E. Denny <jdenny@ces.clemson.edu>
4199 Replace `%push-parser' and `%push-pull-parser' with
4200 `%define push_pull "push"' and `%define push_pull "both"'.
4201 `%define push_pull "pull"' is the default.
4202 * doc/bison.texinfo (Push Decl, Push Parser Function,
4203 Pull Parser Function, Parser Create Function, Parser Delete Function):
4204 Update declarations.
4205 (Decl Summary, Table of Symbols): Replace %push-parser and
4206 %push-pull-parser entries with a %define push_pull entry.
4207 * data/bison.m4 (b4_percent_define_check_values): New macro.
4208 (b4_pull_if, b4_push_if, b4_use_push_for_pull_if): Move these
4210 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
4212 * data/push.c: ... to here and compute them from the value of the
4213 %define variable push_pull.
4214 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
4215 parsing requests here...
4216 * data/yacc.c: ... hack this to switch to push.c any time
4217 b4_use_push_pull_flag or the %define variable push_pull is set. This
4218 will go away when we mv push.c yacc.c.
4219 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
4220 push parsing is not supported since unused %define variables are
4222 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
4223 * src/muscle_tab.h (muscle_percent_define_check_values): Update
4224 comments for consistency with b4_percent_define_check_values.
4225 * src/output.c (prepare): Don't insert b4_pull_flag and b4_push_flag
4227 * src/parse-gram.y (PERCENT_PUSH_PARSER, PERCENT_PUSH_PULL_PARSER):

4234 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Update
4236 (Push Parsing: Multiple impure instances): Update declaration.
4237 (Push Parsing: Unsupported Skeletons): New test case.
4238 * tests/torture.at (Exploding the Stack Size with Alloca): Update
4240 (Exploding the Stack Size with Malloc): Update declaration.
4242 2007-09-24 Wojciech Polak <polak@gnu.org>
4244 Add XSLT transformations.
4246 * data/xslt/xml2dot.xsl: Transform XML into DOT.
4247 * data/xslt/xml2text.xsl: Transform XML into plain text.
4248 * data/xslt/xml2xhtml.xsl: Transform XML into XHTML.
4249 * data/Makefile.am (xsltdir): New variable.
4250 (dist_xslt_DATA): Add xslt/*.xsl files.
4252 2007-09-23 Paul Eggert <eggert@cs.ucla.edu>
4254 * src/conflicts.c (log_resolution): Fix indenting bugs I introduced.
4255 Problem reported by Wojciech Polak.
4256 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.
4257 (xml_printf): Undo change I made on 21 September; that is,
4258 indent 2 spaces, not 1.
4260 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
4262 Pacify ./configure --enable-gcc-warnings.
4263 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
4264 `char const *' instead of `char *'.
4265 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
4266 local variable `sep'.
4268 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
4270 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
4272 * src/print-xml.c: Prefer "const" after types; that's more consistent.
4273 (xml_printf): Indent just 1 space for level.
4274 (e_char, xlate_char): Remove.
4275 (xml_escape_string): Rewrite to avoid undefined behavior (used
4276 storage that was freed from the stack).
4277 (xml_escape_n): Don't bother checking for subscript error.
4279 2007-09-21 Wojciech Polak <polak@gnu.org>
4281 Add Bison XML Automaton Report.
4283 Add support for an -x option to generate an XML report.

4321 * GNUmakefile: Switch to coreutils's version.
4322 * bootstrap: Likewise.
4323 * Makefile.cfg: Adjust to new GNUmakefile.
4324 * README-hacking: Likewise.
4328 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
4329 Bruno Haible <bruno@clisp.org>
4331 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
4332 and is a script that invokes bison. Tighten the code. Add comments.
4334 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>
4336 Spell "boolean" as "Boolean". Reported by Akim Demaille.
4337 * data/bison.m4 (b4_percent_define_flag_if): Fix complaint.
4338 * doc/bison.texinfo (Decl Summary): Fix.
4339 * src/muscle_tab.c (muscle_percent_define_flag_if): Fix complaint.
4340 * tests/input.at (Boolean %define variables): Update output.
4341 * tests/skeletons.at (%define boolean variables: invalid skeleton
4342 defaults): Rename to...
4343 (%define Boolean variables: invalid skeleton defaults): ... this and
4346 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
4348 In impure push mode, don't allow more than one yypstate to be allocated
4349 since multiple impure parsers would corrupt yynerrs.
4350 * data/push.c (yypstate_allocated): New static global variable
4352 (yypull_parse): If yypstate_new returns 0, don't report it as memory
4353 exhaustion if yypstate_allocated is 1, but still return 2.
4354 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
4355 already 1. Otherwise, set it to 1.
4356 (yypstate_delete): Set it to 0.
4357 * tests/push.at (Push Parsing: Multiple impure instances): New test
4360 2007-08-17 Bob Rossi <bob@brasko.net>

4368 Add new push parser symbols.
4369 (Table of Symbols): Document push-parser, push-pull-parser,

4431 Get rid of broken %no-parser, -n, and --no-parser implementation and
4433 * TODO: Don't mention them.
4434 * doc/bison.1: Likewise.
4435 * doc/bison.texinfo (Decl Summary): Likewise.
4436 (Bison Options): Likewise.
4437 (Option Cross Key): Likewise.
4438 * src/getargs.c (no_parser_flag): Remove global variable.
4439 (usage): Don't print description of -n and --no-parser.
4440 (long_options): Remove --no-parser entry here.
4441 (getargs): Remove -n case in the switch here.
4442 * src/getargs.h (no_parser_flag): Remove extern.
4443 * tests/regression.at (Web2c Actions): Remove comment that mentions
4446 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
4448 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
4449 name user variables starting with `yy'. Just pass NULL instead of a
4450 dummy local &yylval to yypush_parse.
4451 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
4454 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
4456 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
4457 true since it's then always used regardless of whether yyoverflow is
4458 defined. Reported by Christian Burger at
4459 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
4460 * THANKS: Add Christian Burger.
4462 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4463 node names: say "Decl Summary" not "Bison Declaration Summary".
4465 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
4467 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
4468 determine whether this function has already complained about an invalid
4469 value for a %define boolean variable, don't check whether Bison has
4470 ever examined the value. As written, the check was a tautology.
4471 Instead, record and check for this complaint using a separate muscle.
4473 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
4475 Fix push parsing memory leak reported by Brandon Lucia at
4476 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
4477 * THANKS: Add Brandon Lucia.
4478 * data/push.c (yypstate_delete): Free the stack if it was reallocated
4479 but the parse never completed and thus freed it.
4480 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
4481 * tests/testsuite.at: Include push.at.
4482 * test/push.at: New.
4483 (Push Parsing: Memory Leak for Early Deletion): New test case.
4485 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
4487 Improve handling of multiple S/R conflicts in the same state and of S/R
4488 conflicts involving multiple reductions.
4489 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
4490 set for a state here or Bison will abort if it is reassigned on a
4491 later conflicted reduction in the same state.
4492 Similarly, don't finalize and assign the solved conflicts report here
4493 or it will be lost if it is reassigned on a later conflicted reduction
4495 (set_conflicts): Instead, assign them both here after all S/R conflicts
4496 in the state have been fully examined.
4497 * src/print.c (shift_set): Rename to...
4498 (no_reduce_set): ... this.
4499 (print_reductions): Update for rename, and add %nonassoc error action
4500 tokens to no_reduce_set so that, when printing the first remaining
4501 reduction on an error action token, the reduction is enclosed in
4503 (print_results): Update for rename.
4504 * tests/conflicts.at (Solved conflicts report for multiple reductions
4505 in a state): New test case.
4506 (%nonassoc error actions for multiple reductions in a state): New test
4509 * src/main.c (main): Don't depend on C99 features.
4511 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
4513 * build-aux/.cvsignore: Add compile.
4514 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
4517 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
4519 * bootstrap (slurp): Create target directories that don't exist.
4520 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
4522 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4524 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
4526 * closure.c (closure): Likewise.
4527 * state.h (reductions): Comment sorting of rules.
4528 (state): Comment sorting of items.
4530 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
4532 Fix C++ test cases after recent Gnulib changes. Discussed starting at
4533 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
4534 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
4535 definition in order to avoid Gnulib headers since we don't use config.h
4537 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
4538 rather than AT_DATA so that config.h is included.
4540 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
4542 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
4543 instead of fprintf. Guard these functions with #if YYDEBUG instead of
4544 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
4545 and so that YYFPRINTF is guaranteed to be defined here.
4547 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4549 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
4551 (muscle_percent_define_check_values): ... this more helpful function.
4552 Again, it's not used yet, but it will be.
4553 * src/muscle_tab.h: Likewise.
4555 Improve some comments in parser table construction.
4556 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
4557 (generate_states): Don't mention ruleset, which is internal to closure.
4558 * src/closure.c (closure): Explain sorting of core and itemset, which
4559 is required for this function to behave correctly.
4560 * src/closure.h (closure): Mention sorting.
4562 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
4564 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4565 move the check for disabled transitions to an aver since conflict
4566 resolution hasn't happened yet.
4568 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4569 labels a state as inconsistent just because it has error transitions.
4570 The original form of this check appeared in revision 1.1 of lalr.c,
4571 which was committed on 1991-12-21. Now (at least), changing the
4572 consistency label on such a state appears to have no useful effect in
4573 any of the places it is examined, which I enumerate below. The key
4574 point to understanding each item in this enumeration is that a state
4575 with an error transition is labelled consistent in the first place only
4576 if it has no rules, so the check cannot matter for states that have
4577 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4578 to try to identify its conflicts, and a state must have *rules* to have
4579 conflicts. (2) Labelling a state as inconsistent will affect how
4580 action_row sets the default *rule* for the state. (3) Labelling a
4581 state as inconsistent will cause build_relations to add lookback edges
4582 to *rules* in that state.
4583 * src/state.h (struct state): Word the comment for member consistent
4586 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
4588 Don't depend on C99 features.
4589 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.

4839 Undo my 2007-02-07 change, switching back to the c-strcase module
4840 introduced in the 2007-02-03 change. Bruno Haible reported that
4841 the 2007-02-07 change would be dangerous in Turkish if we add a
4842 language whose name contains "i", since "i" is not lowercase "I"
4844 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
4845 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
4846 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
4847 * m4/.cvsignore: Remove strcase.m4.
4848 * src/getargs.c: Revert 2007-02-07 change, as follows.

4850 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
4852 2007-02-11 Bruno Haible <bruno@clisp.org>
4854 Enable the Java related testsuite tests when the only Java compiler
4855 found is a gcj < 4.3. Discussed at
4856 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
4857 * configure.ac (gt_JAVACOMP): Don't specify a target_version.

4865 * src/reader.c (packgram): Move translation of rule actions from the
4866 beginning of packgram to...
4867 (check_and_convert_grammar): ... here right before packgram is invoked
4868 so it's easier to write more complete comments, and remove redundant
4871 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
4873 As in semantic actions, make @$ in %initial-action, %destructor, and
4874 %printer imply %locations.
4875 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
4877 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
4878 (@$ in %initial-action implies %locations,
4879 @$ in %destructor implies %locations,
4880 @$ in %printer implies %locations): ... these new test cases.
4882 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>

4885 now that gnulib strcase has been fixed.
4886 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
4887 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
4888 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
4889 * m4/.cvsignore: Add strcase.m4.
4890 * src/getargs.c: Revert 2007-02-03 change, as follows.
4891 Don't include c-strcase.h.
4892 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4893 strcasecmp has "unspecified behavior" outside the POSIX locale,
4894 but it works fine in practice if at least one argument is ASCII,
4895 as is the case in Bison.
4897 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
4899 * tests/java.at: Skip tests if only one of javac/java is present.
4900 Reported by Joel E. Denny.
4901 * tests/atlocal.in: Adjust copyright years.
4903 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
4905 * data/lalr1.java (Stack): Work around old verifiers that disallow
4906 access to the private fields of an inner class, from the outer class.
4907 We can make Stack's fields public because user code doesn't have access
4908 to the instance of Stack used by parse(). Reported by Paul Eggert.
4910 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4912 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4913 the right spot for these files?
4914 * bootstrap.conf (gnulib_modules): Add c-strcase.
4915 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4917 * src/getargs.c: Include c-strcase.h.
4918 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4919 to avoid unspecified behavior.
4921 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
4923 * doc/bison.texinfo (Decl Summary): Correct typo.
4925 2007-01-30 Paolo Bonzini <bonzini@gnu.org>

4929 * data/c++.m4: Adjust default definitions of %define variables.
4930 * data/java.m4: Adjust default definitions of %define variables.
4931 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according

4955 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
4956 * tests/java.at: New.
4957 * tests/testsuite.at: Include it.
4959 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
4962 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4963 at_directive_argv arguments so these no longer have to be global
4964 variables. Also, update the implementation for the following changes.
4965 (fail_for_at_directive_too_many_args,
4966 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4967 (at_directive_name): Remove as at_directive_argv[0] will be used for
4969 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4970 for the directive name.

4974 (SC_AT_DIRECTIVE_ARG): Rename to...
4975 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4976 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4977 (scan_skel): Move yylex_destroy to...
4978 (skel_scanner_free): ... here.
4979 * tests/skeletons.at (installed skeleton file name): Rename to...
4980 (installed skeleton file names): ... this.
4982 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4984 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4985 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4986 Summary" not "Directives".
4987 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4988 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4989 since the former is now the more complete one.
4990 (Prologue Alternatives): Likewise and do the same for %defines.
4991 (Table of Symbols): Add summary of %code, add summary of %define, and
4992 move full %code documentation to...
4993 (Decl Summary): ... here for consistency with other entries in these
4995 Move %define entry in order to keep this list alphabetized.
4996 Reword %define entry a little to put less emphasis on the skeleton
4997 concept, which most users shouldn't have to think about.

5008 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
5010 Simplify implementation of unqualified %code, implement macros for
5011 uniform treatment of boolean %define flags. Document %define.

5080 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
5081 and Joel E. Denny <jdenny@ces.clemson.edu>
5083 Clean up %define and %code implementation in M4 some. Most
5084 importantly, rename all related macros to be in the b4_percent_define
5085 and b4_percent_code namespaces. Also, complete support for `.' in
5086 %define variable names and %code qualifiers.
5087 * data/bison.m4 (b4_check_user_names): Check for special
5088 "SKELETON-NAMESPACE(name)" macros instead of using two nested
5090 (b4_get_percent_define, b4_get_percent_code): Rename to...
5091 (b4_percent_define_get, b4_percent_code_get): ... these.
5092 Extend documentation with examples.
5093 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
5094 b4_percent_define_skeleton_variables and
5095 b4_percent_code_skeleton_qualifiers.
5096 Expect any value for the %define variable `foo' to be stored in the
5097 macro named `b4_percent_define(foo)'; expect any %code blocks for the
5098 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
5099 expect any unqualified %code blocks to be stored in a macro named
5100 `b4_percent_code_unqualified'.
5101 Use m4_indir so that %define variable names and %code qualifiers can
5102 contain `.', which is allowed by the grammar parser.
5103 (b4_percent_define_default): New macro to set a default value for a
5105 (m4_wrap): Update wrapped code, and fix some underquoting.
5106 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
5107 Expect grammar uses of %define variables and %code qualifiers to be
5108 defined in b4_percent_define_user_variables and
5109 b4_percent_code_user_qualifiers.
5110 * data/c++.m4: Use b4_percent_define_default rather than
5111 m4_define_default. Fix some underquoting. Skeleton usage of %define
5112 variable define_location_comparison now implies skeleton usage of
5113 %define variable filename_type.
5114 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5115 data/push.c, data/yacc.c: Update macro names.
5116 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
5119 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5121 DJGPP specific issues.
5123 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
5124 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
5126 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5128 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
5129 run parsers in all tests so that Valgrind is invoked during
5130 maintainer-check-valgrind.
5131 (Duplicate representation of merged trees): Free all semantic values.
5132 (Duplicated user destructor for lookahead): Likewise.
5134 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5136 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
5137 command-line prefix.
5138 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
5139 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
5140 miss Valgrind messages.
5141 (Exploding the Stack Size with Malloc): Likewise.
5143 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5145 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
5146 locals. Reported by Juan Manuel Guerrero at
5147 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
5148 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
5149 Fix some indentation also.
5150 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
5151 explaining this issue.
5153 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
5154 and Joel E. Denny <jdenny@ces.clemson.edu>
5156 Simplify union and prologue handling, and escape union and lex/parse
5157 params with digraphs.
5158 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
5159 values to the empty string since these are no longer guaranteed
5160 initialized by the front-end.
5161 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
5162 braces around b4_user_stype since this is no longer done by the
5164 * src/files.c, src/files.h (pre_prologue_obstack,
5165 post_prologue_obstack): Remove.
5166 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
5167 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
5168 with digraphs. This fixes lex params and parse params.
5169 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
5170 * src/output.c (prepare): Remove muscle insertion of the prologues.
5171 (output): Remove freeing of pre_prologue_obstack and
5172 post_prologue_obstack.
5173 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
5174 than prologue_augment for prologue parsing so you don't need prologue
5176 (grammar_declaration): For %union RHS, use `braceless' instead of
5177 "{...}" so that braces are already stripped and code is escaped with
5179 * src/reader.c (prologue_augment): Remove.
5180 (reader): Remove initialization of pre_prologue_obstack and
5181 post_prologue_obstack.
5182 * src/reader.h (prologue_augment): Remove.
5184 * data/c.m4: Remove stray parenthesis.
5186 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5188 Remove quotes from variables names in %define directives and from
5189 qualifiers in %code directives, and restrict the characters that are
5190 allowed in them to M4-friendly ones. For %define, continue to support
5191 the quoted form as a deprecated feature. Discussed starting at
5192 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
5193 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
5195 * doc/bison.texinfo (Prologue Alternatives): Update.
5196 (Decl Summary): In %defines entry, update mention of `%code requires'
5197 and `%code provides'.
5198 (C++ Location Values): Update %define uses.
5199 (Calc++ Parser Interface): Likewise.
5200 (Calc++ Parser): Likewise, and update `%code requires' uses.
5201 (Table of Symbols): Update %code documentation.
5202 * src/parse-gram.y (prologue_declaration): For %define variables, use
5203 `variable' instead of `STRING'.
5204 (grammar_declaration): For %code qualifiers, use `ID' instead of
5206 (variable): New nonterminal that takes an `ID' or a `STRING'.
5207 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
5209 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
5210 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
5211 (%define errors): Update %define uses.
5213 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5215 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
5216 instead of muscle_insert for %define values so that M4-special
5217 characters are replaced with digraphs.
5218 * tests/input.at (%define errors): Extend to check weird values.
5220 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
5222 Instead of having skeletons declare all valid %define variables and
5223 %code qualifiers, provide macros that retrieve the associated values
5224 and build these lists automatically. Thus Bison will now warn when a
5225 variable or qualifier is not used by the skeleton in the current
5226 invocation regardless of whether it might sometimes be used by that
5227 skeleton in other invocations. Also, move all %define value macros to
5228 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
5229 form, which is replaced by %code.
5230 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
5231 (b4_check_user_names): ... this, and change the series of valid name
5232 arguments to a single list argument for names used in the skeleton
5233 similar to the existing list argument for names used in the grammar.
5234 Warn instead of complaining.
5235 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
5236 values and %code code, to format %code code properly, and to build
5237 lists of all %define variables and %code qualifiers used in the
5238 skeleton: b4_skeleton_percent_define_variables and
5239 b4_skeleton_percent_code_qualifiers.
5240 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
5242 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
5243 the skeleton names lists can finish building first. In place of
5244 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
5245 expect the lists b4_user_percent_define_variables and
5246 b4_user_percent_code_qualifiers.
5247 * data/c++.m4: Where setting default values for b4_parser_class_name,
5248 b4_location_type, b4_filename_type, b4_namespace, and
5249 b4_define_location_comparison, update their names to the
5250 b4_percent_define_ namespace.
5251 * data/glr.c: Don't use b4_check_percent_define_variables and
5252 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
5253 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
5254 (b4_parser_class_name, b4_namespace): Define these using
5255 b4_get_percent_define for parser_class_name and namespace.
5256 * data/location.cc: Use b4_get_percent_define.
5257 * data/push.c: Don't use b4_check_percent_define_variables and
5258 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
5259 * data/yacc.c: Likewise, and don't call m4_exit in
5260 b4_use_push_for_pull_if or m4_wrap code will never execute.
5261 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
5263 (muscle_grow_user_name_list): ... this for consistency with the
5264 terminology used in bison.m4.
5265 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
5266 %define variable names, and rename muscle used_percent_define_variables
5267 to user_percent_define_variables.
5268 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
5269 user_percent_code_qualifiers.
5271 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
5272 {CODE} form is no longer accepted.
5273 * tests/input.at (Reject bad %code qualifiers): Rename to...
5274 (Reject unused %code qualifiers): ... this, and update test output.
5275 (%define error): Update test output.
5277 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
5279 Check for unrecognized %define variables similar to checking for
5280 unrecognized %code qualifiers. Check for redefined %define variables.
5281 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
5283 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
5284 (b4_check_percent_define_variables): New, also wraps it.
5285 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
5286 variables using b4_check_percent_define_variables.
5287 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
5288 all those exercised in the test suite and all those listed in the
5289 `Default values' section of c++.m4. Are there others?
5290 * data/push.c, data/yacc.c: Declare no valid %define variables.
5291 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
5292 similar to muscle_find, but it works even when the muscle stores a
5294 (muscle_grow_used_name_list): New function for constructing the used
5295 name list muscles that b4_check_for_unrecognized_names requires.
5296 * src/parse-gram.y (prologue_declaration): Warn if a variable is
5297 %define'd more than once. Define the b4_used_percent_define_variables
5298 muscle with muscle_grow_used_name_list.
5299 (grammar_declaration): Abbreviate %code code with
5300 muscle_grow_used_name_list.
5301 * tests/input.at (%define errors): New.
5303 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5305 Provide warn_at, complain_at, and fatal_at function callbacks to the
5306 skeletons, and use this for %code qualifier complaints.
5307 * data/bison.m4 (b4_error_at): New, invoked by...
5308 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
5309 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
5310 @fatal_at(...@) directives.
5311 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
5312 qualifiers in b4_used_percent_code_qualifiers and to use
5314 * src/location.c, src/location.h (boundary_set_from_string): New global
5316 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
5318 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
5319 to b4_used_percent_code_qualifiers.
5320 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
5322 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
5323 (lineno): Rename to...
5324 (out_lineno): ... this so I don't misunderstand it again.
5325 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
5326 here; these newlines are in the input but not the output file.
5327 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
5328 (at_directive_perform): ... this new static function, and add handling
5329 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
5331 * tests/input.at (Reject bad %code qualifiers): Update test output with
5332 locations and extend.
5334 * tests/output.at (Output file name: [, Output file name: ]): Remove
5335 bogus comment about these tests failing.
5337 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5339 Clean up b4_check_percent_code_qualifiers a little.
5340 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
5341 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
5342 documentation and add examples.
5343 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
5346 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5348 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
5349 unreliable -- especially when they're hidden inside another macro.
5350 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
5351 data/c.m4: Remove m4_divert(-1).
5352 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5353 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
5354 m4_divert_push(0) and m4_divert_pop(0).
5355 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
5356 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
5357 pushed and popped by m4sugar, should be first on the stack.
5359 Provide warn, complain, and fatal function callbacks to the skeletons.
5360 This provides more flexibility than m4_fatal, improves the error
5361 message format, and captures messages for translation. Discussed
5363 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
5364 * data/bison.m4 (b4_error): New, invoked by...
5365 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
5366 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
5367 directives. Because these M4 macros might be called when the current
5368 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
5369 the previous removal of uses of m4_divert, which caused trouble.
5370 (b4_check_percent_code_qualifiers): Use b4_complain instead of
5371 m4_fatal to report unrecognized %code qualifiers.
5372 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
5373 push parser requests.
5374 * data/glr.c: Use b4_complain instead of m4_fatal to report
5375 non-deterministic push parser requests.
5376 Update @output usage to @output(...@) form.
5377 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
5378 report missing %defines. Update @output usage to @output(...@) form.
5379 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
5381 * src/main.c (main): Invoke skel_scanner_free.
5382 * src/scan-skel.h (skel_scanner_free): Prototype new function.
5383 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
5384 obstack_for_string from flex-scanner.h.
5385 (YY_DECL): Use to declare skel_lex static.
5386 (decode_at_digraphs): Remove; now handled in the new
5387 SC_AT_DIRECTIVE_ARG start condition.
5388 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
5390 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
5391 at_directive_argv): New static globals.
5392 (INITIAL): Use fail_for_invalid_at.
5393 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
5394 recognize the start of a generalized `@directive(...@)' form and
5396 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
5397 directive args (using the new obstack_for_string), to decode the
5398 contained @ diagraphs, and to perform the directive. It recognizes
5399 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
5401 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
5402 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
5404 (scan_skel): Initialize obstack_for_string on the first call.
5405 (skel_scanner_free): New function to free obstack_for_string.
5406 * tests/input.at (Reject bad %code qualifiers): Update test output.
5408 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
5410 Consolidate the 4 prologue alternative directives (%code, %requires,
5411 %provides, and %code-top) into a single %code directive with an
5412 optional qualifier field. Discussed at
5413 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
5414 * NEWS (2.3a+): Rewrite the existing entry for the prologue
5416 * doc/bison.texinfo (Prologue Alternatives): Update.
5417 (Decl Summary): Update to %code "requires" and %code "provides".
5418 (Calc++ Parser): Update to %code "requires".
5419 (Table of Symbols): Remove entries for %requires, %provides, and
5420 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
5421 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
5422 are replaced by b4_percent_code_provides and b4_percent_code_requires,
5423 which are skeleton-specific.
5424 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
5425 declare what %code qualifiers it supports and to complain if any other
5426 qualifiers were used in the grammar.
5427 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
5428 and b4_user_code([b4_percent_code_provides]) in place of
5429 b4_user_requires and b4_user_provides.
5430 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
5431 Add b4_user_code([b4_percent_code_top]) and
5432 b4_user_code([b4_percent_code]).
5433 Invoke b4_check_percent_code_qualifiers.
5434 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
5435 PERCENT_REQUIRES): Remove.
5436 (grammar_declaration): Remove RHS's for %code-top, %provides, and
5437 %requires. Rewrite the %code RHS as the unqualified form defining the
5438 muscle b4_percent_code. Add another RHS for the qualified %code form,
5439 which defines muscles of the form b4_percent_code_QUALIFIER and the
5440 b4_used_percent_code_qualifiers muscle.
5441 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
5442 PERCENT_REQUIRES): Remove.
5443 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
5444 %code "requires" and %code "provides".
5445 * tests/input.at (Reject bad %code qualifiers): New.
5447 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
5449 Use the new code_props interface for destructors and printers.
5450 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
5451 printer_location members, and change the type of the destructor and
5452 printer members to code_props.

5455 semantic_type_printer_set, default_tagged_destructor_set,
5456 default_tagless_destructor_set, default_tagged_printer_set,
5457 default_tagless_printer_set): Use code_props in arguments and return
5458 types in place of char const * and location.
5459 (symbol_destructor_location_get, symbol_printer_location_get): Remove
5460 since the locations are now contained in the return of
5461 symbol_destructor_get and symbol_printer_get.
5462 * src/output.c (symbol_destructors_output, symbol_printers_output):
5464 (symbol_code_props_output): ... this to eliminate duplicate code.
5465 (output_skeleton): Update to use symbol_code_props_output.
5466 * src/reader.c (symbol_should_be_used): Update use of
5467 symbol_destructor_get.
5468 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5469 Update uses of the various _destructor_set and _printer_set functions.
5470 * src/symtab.c: (default_tagged_destructor_location,
5471 default_tagless_destructor_location, default_tagged_printer_location,
5472 default_tagless_printer_location): Remove since we...
5473 (default_tagged_destructor, default_tagless_destructor,
5474 default_tagged_printer, default_tagless_printer): ... change the type
5475 of these to code_props.

5483 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
5485 (symbol_print): Use SYMBOL_CODE_PRINT.
5487 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
5489 Use the new code_props interface for rule actions.
5490 * src/symlist.h (symbol_list): Replace action, action_location, and
5491 used members with a code_props action_props member.
5492 * src/reader.c (symbol_should_be_used, grammar_rule_check,
5493 grammar_midrule_action, grammar_current_rule_merge_set,
5494 grammar_current_rule_symbol_append, packgram): Update.
5495 * src/scan-code.h (translate_rule_action): Remove, no longer used.
5496 * src/scan-code.l (handle_action_dollar): Update.
5497 (translate_rule_action): Remove, no longer used.
5498 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
5500 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5502 Use the new code_props interface in parse-gram.y.
5503 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
5504 Update all uses of translate_* functions to use the new code_props
5505 interface and to use gram_scanner_last_string_free and
5506 code_scanner_last_string_free where possible.
5507 (grammar_declaration): symbol_list_destructor_set and
5508 symbol_list_printer_set now perform the translation, so don't do it
5509 here. Use gram_scanner_last_string_free where possible.
5510 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
5511 translate_code): Remove, no longer used.
5512 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
5513 symbol_list_printer_set): Perform code translation here rather than
5514 depending on the caller to do so.
5516 * src/symlist.h (struct symbol_list): Correct some documentation typos.
5517 * src/scan-gram.h (gram_last_string): Remove declaration.
5518 * src/scan-gram.l (last_string): Declare it static.
5520 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
5522 Encapsulate code properties and related functionality for the various
5523 destructors, printers, and actions into a code_props structure and
5524 interface. This patch merely implements code_props in scan-code.h and
5525 scan-code.l. Future patches will rewrite other modules to use it.
5526 Discussed starting at
5527 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
5528 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
5529 consistently initialize const structs that have an empty location
5531 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
5532 to ensure consistency.
5533 * src/scan-code.h (code_props): New structure.
5534 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
5535 function, macro, and const global variable for initializing a
5536 code_props with no code.
5537 (code_props_plain_init, code_props_symbol_action_init,
5538 code_props_rule_action_init, code_props_translate_code): The rest of
5539 the new code_props functional interface. Among other things, the init
5540 functions set the code_props kind field so that
5541 code_props_translate_code will know whether to behave like
5542 translate_symbol_action, translate_rule_action, or translate_code.
5543 These old translate functions must remain until all other modules are
5544 updated to use the new code_props interface.
5545 (code_scanner_last_string_free): New function similar to
5546 gram_scanner_last_string_free.
5547 (code_scanner_free): Add documentation.
5548 * src/scan-code.l: Implement the new interface.
5549 (code_lex): Make it static, add a code_props* argument, and remove the
5551 (last_string): New static global similar to the one in scan-gram.l.
5552 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
5554 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
5555 code_props since Bison may one day use this information for destructors
5557 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
5558 (handle_action_dollar): Use symbol_list_n_get and set used flag
5559 directly since symbol_list_n_used_set is removed.
5560 (translate_action): Add a code_props* argument and remove the rule,
5561 action, and location arguments. Pass the code_props* on to code_lex.
5562 (translate_rule_action, translate_symbol_action, translate_code):
5563 Rewrite as wrappers around the new code_props interface.
5564 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
5565 it would eventually need to break the encapsulation of code_props.
5567 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5569 * etc/.cvsignore: New.
5571 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
5573 Add maintainer-push-check to run maintainer-check using push parsing in
5574 place of pull parsing where available.
5575 * Makefile.am (maintainer-push-check): New.
5576 * data/bison.m4 (b4_use_push_for_pull_if): New.
5577 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
5578 appropriately based on their existing values.
5579 (yypush_parse): Don't print push-parser-specific diagnostics if push
5580 parsing is being used in place of pull parsing.
5581 * data/yacc.c: If push parsing should replace pull parsing, redirect to
5583 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
5584 variable, and insert b4_use_push_for_pull_flag into muscles.
5585 * tests/Makefile.am (maintainer-push-check): New.
5587 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5589 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
5590 (whether successful or failed) so that yypush_parse can be invoked
5591 again to start a new parse using the same yypstate.
5592 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
5593 check multiple yypull_parse invocations on the same yypstate. For pull
5594 mode, extend to check multiple yyparse invocations.
5595 (Exploding the Stack Size with Alloca): Extend to try with
5597 (Exploding the Stack Size with Malloc): Likewise.
5599 * tests/calc.at (Simple LALR Calculator): Don't specify
5600 %skeleton "push.c" since %push-pull-parser implies that now.
5601 * tests/headers.at (export YYLTYPE): Don't check for the push
5602 declarations. Otherwise, this test case can't be used to see if push
5603 mode can truly emulate pull mode.
5604 * tests/input.at (Torturing the Scanner): Likewise.
5605 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
5606 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
5607 AT_YACC_IF, which now includes the case of push mode since %skeleton
5608 need not be used for push mode. This will be more intuitive once
5609 push.c is renamed to yacc.c.
5611 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
5613 For push mode, convert yyparse from a macro to a function, invoke yylex
5614 instead of passing a yylexp argument to yypull_parse, and don't
5615 generate yypull_parse or yyparse unless %push-pull-parser is declared.
5616 Discussed starting at
5617 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
5618 * data/bison.m4 (b4_pull_if): New.
5619 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
5620 * data/push.c: Improve M4 quoting a little.
5621 (b4_generate_macro_args, b4_parenthesize): Remove.
5622 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
5623 any time a pull parser is requested.
5624 Don't #define this as a wrapper around yypull_parse. Instead, when
5625 both push and pull are requested, make it a function that does that
5627 (yypull_parse): If there's a b4_prefix, #define this to
5628 b4_prefix[pull_parse] when both push and pull are requested.
5629 Don't define this as a function unless both push and pull are
5631 Remove the yylexp argument and hard-code yylex invocation instead.
5632 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
5634 * src/getargs.c (pull_parser): New global initialized to true.
5635 * getargs.h (pull_parser): extern it.
5636 * src/output.c (prepare): Insert pull_flag muscle.
5637 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
5638 (prologue_declaration): Set both push_parser and pull_parser = true for
5639 %push-pull-parser. Set push_parser = true and pull_parser = false for
5641 * src/scan-gram.l: Don't accept %push_parser as an alternative to
5642 %push-parser since there's no backward-compatibility concern here.
5643 Scan %push-pull-parser.
5644 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
5645 instead of %push-parser.
5646 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
5647 prototype it in the module that calls yyparse.
5648 * tests/input.at (Torturing the Scanner): Likewise.
5649 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
5651 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
5653 Update etc/bench.pl. Optimize push mode a little (the yyn change
5654 deserves most of the credit).
5655 * Makefile.am (SUBDIRS): Add etc subdirectory.
5656 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
5657 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
5658 yytoken, yyval, and yyloc declarations to...
5659 (yyparse or yypush_parse): ... here to improve performance. For
5660 yypush_parse invocations after the first, be sure to assign yyn its old
5662 (yypstate_new): Don't bother initializing the yyresult field since the
5663 initial value isn't used.
5664 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
5665 remove the #define that, in push mode, set it to yyps->NAME.
5666 * etc/Makefile.am: New.
5667 * etc/bench.pl: Remove and build it instead from...
5668 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
5669 "tests/bison" from the build directory by default rather than just
5670 invoking "bison" from $PATH.
5671 (calc_grammar): Update push parser code: don't declare yylval globally,
5672 don't define yyparse_wrapper, and don't #define yyparse.
5673 (bench_grammar): Update to check all working combinations of yacc.c,
5674 push.c, impure, pure, pull, and push.
5676 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5678 For push mode, add pull wrappers around yypush_parse.
5679 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
5680 (yypull_parse): New function wrapping yypush_parse.
5681 (yyparse): New #define wrapping yypull_parse.
5682 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
5684 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
5685 prototype yylex in the module that calls yyparse, and don't prototype
5686 yyparse there. Otherwise, the yyparse expansion won't compile.
5687 * tests/input.at (Torturing the Scanner): Likewise.
5689 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
5691 Enable push parsers to operate in impure mode. Thus, %push-parser no
5692 longer implies %pure-parser. The point of this change is to move
5693 towards being able to test the push parser code by running the entire
5694 test suite as if %push-parser had been declared.
5695 * data/push.c (yypush_parse): For impure mode, remove the
5696 yypushed_char, yypushed_val, and yypushed_loc arguments.
5697 Instead, declare these as local variables initialized to the global
5698 yychar, yylval, and yylloc.
5699 For the first yypush_parse invocation only, restore the initial values
5700 of these global variables when it's time to read a token since they
5701 have been overwritten.
5702 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
5704 * tests/calc.at (Simple LALR(1) Calculator): Always declare
5705 %pure-parser along with %push-parser since this test case was designed
5706 for pure push parsers.
5707 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
5708 (AT_YACC_OR_PUSH_IF): New.
5709 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
5710 add a note that it's still wrong for some cases (as it has been for a
5712 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
5713 %push-parser no longer implies %pure-parser.
5715 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5717 Remove some unnecessary differences between the pull parser code and
5718 the push parser code. This patch enables yynerrs in push mode.
5719 * data/push.c: Reformat M4 a little.
5720 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
5721 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
5722 because push mode is on. Instead, if pure mode is on, move yynerrs
5724 (b4_declare_parser_state_variables): ... here.
5725 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
5726 to yyps->NAME so it can be used in yypush_parse.
5727 (yypush_parse): Don't omit uses of yynerrs in push mode.
5729 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5731 Fix bug such that the first pushed token's value and location are
5732 sometimes overwritten (sometimes by %initial-action) before being used.
5733 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
5734 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
5735 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
5736 more closely mimic the pull parser logic.
5737 Don't copy the pushed token to yychar, yylval, and yylloc until it's
5738 time to read a token, which is after any initialization of yylval and
5740 (gottoken): Rename label to...
5741 (yyread_pushed_token): ... for clarity and to avoid infringing on the
5744 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5746 Rearrange initialization of the parser state variables so that the
5747 skeleton doesn't have to have a copy for pull mode and another for push
5748 mode. This patch also fixes at least a bug such that yylloc was not
5749 initialized (with b4_location_initial_line and
5750 b4_location_initial_column) upon calling yypush_parse. However, that
5751 initialization now overwrites the first token's location;
5752 %initial-action assigning @$ already did the same thing, and both bugs
5753 will be fixed in a later patch.
5754 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
5755 (b4_declare_parser_state_variables): Remove initialization of yytoken,
5756 yyss, yyvs, yyls, and yystacksize.
5757 (yypstate_new): Remove initialization of some yypstate fields: yystate,
5758 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
5760 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
5761 yyps->NAME so it can be used in yypush_parse.
5762 (yyparse or yypush_parse): For yypush_parse, don't print the
5763 "Starting parse" diagnostic for invocations after the first.
5764 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
5765 yypush_parse, only do it for the first invocation.
5766 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
5767 initialization to occur in yypush_parse but only on the first
5770 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5772 * data/push.c: Add CPP guards around push parser declarations in both
5773 the header and the code file.
5774 In the code file, move the push parser declarations to the same place
5775 they appear in the header file.
5776 Clean up the M4 some, especially the inconsistent underquoting in
5777 some b4_c_function_def and b4_c_function_decl uses.
5779 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5781 Encapsulate the push parser state variables into an M4 macro so the
5782 push skeleton doesn't have to list them again for pull mode's yyparse.
5783 For push mode, remove yypush_parse's local equivalents of these
5784 variables to eliminate unnecessary copying between the two sets at
5785 run-time. This patch also fixes at least a bug related to multiple
5786 %initial-action invocations in push mode.
5787 * data/push.c (b4_declare_parser_variables): Rename to...
5788 (b4_declare_scanner_communication_variables): ... this for clarity and
5790 (b4_declare_yyparse_variables): Remove and move its contents to the one
5791 spot where it was invoked.
5792 (b4_declare_parser_state_variables): New macro containing the parser
5793 state variables required by push mode.
5794 (struct yypstate): Replace all fields but yynew with
5795 b4_declare_parser_state_variables.
5796 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
5797 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
5798 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
5799 (yyparse or yypush_parse): For yyparse in pull mode, replace local
5800 parser state variable declarations with
5801 b4_declare_parser_state_variables.
5802 Don't initialize parser state variables when calling yypush_parse since
5803 yypstate_new already does that.
5804 Invoke the user's initial action only upon the first yypush_parse
5806 Remove all code that copies between the local parser state variables
5809 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5811 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
5812 prevent a name collision in a future patch where these names will
5813 sometimes be #define'd.
5814 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
5815 since it no longer has the same name as the existing argument.
5816 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
5818 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
5819 and Joel E. Denny <jdenny@ces.clemson.edu>
5821 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
5822 that the argument is case-insensitive, and there's no `=' here.
5823 For the %skeleton entry, mention that %language is better.
5824 (Bison Options): Likewise for --language and --skeleton. Move the
5825 --skeleton entry so that the `Tuning the parser' section is sorted
5826 alphabetically on long options.
5827 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
5828 %language directive in detail here; cross-reference the %language
5829 documentation instead.
5830 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
5831 `%require "2.3b"' so that the example is always up-to-date.
5832 (Table of Symbols): Add entries for %language and %skeleton.
5833 * examples/extexi (normalize): Instead of replacing every %require
5834 argument with the current Bison version, just substitute for
5835 `@value{VERSION}'. This guarantees that we're testing what actually
5836 appears in the documentation.
5837 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
5838 rather than `@VERSION@'.
5840 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5842 * NEWS: Reword the %language news a bit, and put it earlier.
5844 * src/getargs.c (skeleton_arg): Last arg is now location const *.
5845 Rewrite to simplify the logic.
5846 (language_argmatch): Likewise.
5847 (program_name): We now own this var.
5848 * src/getargs.h (struct bison_language): Use char[] rather than
5851 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
5853 * src/complain.c (program_name): Remove decl; no longer needed.
5854 * src/main.c (program_name): Remove; now belongs to getargs.
5856 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
5858 * NEWS: Document %language.
5860 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
5862 * data/c-skel.m4, data/c++-skel.m4: New files.
5863 * data/glr.c: Complain on push parsers.
5865 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
5867 (Decl Summary): Document %language and %skeleton.
5868 (Command line): Document -L.
5870 * examples/extexi: Rewrite %require directive.
5871 * examples/calc++/Makefile.am: Pass VERSION to extexi.
5873 * src/files.c (compute_exts_from_gc): Look in language structure
5875 (compute_file_name_parts): Check whether .tab should be added.
5876 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
5877 (language, skeleton_arg, language_argmatch): New.
5878 (long_options): Add --language.
5879 (getargs): Use skeleton_arg, add -L/--language.
5880 * src/getargs.h: Include location.h.
5881 (struct bison_language, language, skeleton_arg, language_argmatch): New.
5882 * src/output.c (prepare): Pick default skeleton from struct language.
5883 Don't dispatch C skeletons here.
5884 * src/parse-gram.y (PERCENT_LANGUAGE): New.
5885 (prologue_declaration): Add "%language" rule, use skeleton_arg.
5886 * src/scan-gram.l ("%language"): New rule.
5888 * tests/calc.at: Test %skeleton and %language.
5889 * tests/local.at (AT_SKEL_CC_IF): Look for %language.

5892 (AT_YACC_IF): Reject %language.
5894 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5896 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5897 since it wasn't used; only the typedef name 'semantic_type' is needed.
5898 Also, omit trailing white space.
5900 * bootstrap: Sync from coreutils.
5901 (gnulib_extra_files): Add build-aux/announce.gen.
5902 (slurp): Adjust .gitignore files like .cvsignore files.
5903 * build-aux/announce-gen: Remove from CVS, since bootstrap
5906 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5908 Make %push-parser imply %pure-parser. This fixes several bugs; see
5909 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5910 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5912 * data/push.c: Don't bother testing b4_push_if when deciding whether
5913 to expand b4_declare_parser_variables globally.
5914 (yypush_parse): Likewise in here.
5916 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5917 (yy_reduce_print): Reformat M4 for readability.
5919 2006-12-15 Bob Rossi <bob@brasko.net>
5920 and Joel Denny <jdenny@ces.clemson.edu>
5922 * data/push.c (yypstate): Add typedef, and update all uses of
5923 struct yypstate to just yypstate.
5924 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5926 2006-12-14 Bob Rossi <bob@brasko.net>
5928 * data/push.c (yypush_parse): Declare prototype regardless of
5931 2006-12-14 Bob Rossi <bob@brasko.net>
5933 * data/push.c (yyparse): Remove the prototype and the #define when in
5936 2006-12-13 Bob Rossi <bob@brasko.net>
5938 * data/push.c (yypstate_init): Rename to...
5939 (yypstate_new): ... this and use b4_c_function_def.
5940 (yypstate_delete): New.
5941 (yypush_parse): Change parameters yynval and yynlloc to be const.
5942 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5943 yypstate_delete functions.
5945 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5947 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5948 strange test case titles. Reported by Bob Rossi.
5950 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5952 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5953 of potential ambiguities in GLR grammers.
5955 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5957 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5958 `bison ', use m4_index instead of m4_substr since chopping up a string
5959 containing M4-special characters causes problems here.
5961 Fix a couple of bugs related to special characters in user-specified
5962 file names, and make it easier for skeletons to compute output file
5963 names with the same file name prefix as Bison-computed output file
5965 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5966 b4_parser_file_name and b4_spec_defines_file instead of
5967 @output_parser_name@ and @output_header_name@, which are now redundant.
5968 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5969 b4_parser_file_name, b4_spec_defines_file, and the new
5970 @basename(FILENAME@) instead of @output_parser_name@ and
5971 @output_header_name@, which inappropriately escaped the file names as
5973 * src/files.c (all_but_ext): Remove static qualifier.
5974 (compute_output_file_names): Move `free (all_but_ext)' to...
5975 (output_file_names_free): ... here since all_but_ext is needed later.
5976 * src/files.h (all_but_ext): Extern.
5977 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5978 exactly what MUSCLE_INSERT_STRING used to do.
5979 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5980 characters are escaped properly.
5981 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5983 For pkgdatadir muscle, maintain previous functionality by using
5984 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5985 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5986 digraphs would never be expanded. Hopefully no one has M4-special
5987 characters in his Bison installation path.
5988 * src/scan-skel.l: Don't parse @output_header_name@ and
5989 @output_parser_name@ anymore since they're now redundant.
5990 In @output, use decode_at_digraphs.
5991 Parse a new @basename command that invokes last_component.
5992 (decode_at_digraphs): New.
5993 (BASE_QPUTS): Remove unused.
5994 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
5995 (Output file name): New tests.
5997 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
5999 Warn about output files that are generated by the skeletons and that
6000 conflict with other output files.
6001 * data/glr.c: Don't generate the header file here when glr.cc does.
6002 * src/files.c (file_names, file_names_count): New static globals.
6003 (compute_output_file_names): Invoke output_file_name_check for files
6004 not generated by the skeletons and remove existing checks.
6005 (output_file_name_check): New function that warns about conflicting
6007 (output_file_names_free): Free file_names.
6008 * src/files.h (output_file_name_check): Declare.
6009 * src/scan-skel.l: Invoke output_file_name_check for files generated by
6011 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
6012 (Conflicting output files): New tests.
6014 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6016 * doc/bison.texinfo: Fix a couple of typos.
6018 2006-12-08 Bob Rossi <bob@brasko.net>
6020 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
6022 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
6024 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
6025 (yypush_parse): Rename yypvars argument to yyps and remove redundant
6027 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
6028 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
6030 2006-12-07 Bob Rossi <bob@brasko.net>
6031 and Joel Denny <jdenny@ces.clemson.edu>
6033 * data/push.c (yypvarsinit): Change return type from void* to struct
6034 yypvars*. No longer cast to void* on return.
6035 (struct yypvars): Remove yylen since it need not be remembered between
6036 yypushparse invocations.
6037 (yypushparse): Don't copy between yylen and pv->yylen.
6039 2006-12-05 Bob Rossi <bob@brasko.net>
6041 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
6042 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
6043 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
6044 (struct yypvars): Remove b4_declare_parser_variables.
6045 (yypvarsinit): Remove init code for removed variables.
6046 (global scope): Do not declare b4_declare_parser_variables if
6048 (yypushparse): Add b4_declare_parser_variables.
6049 Init new local variables, and remove init code for removed
6052 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
6053 and yyparse for other modes.
6054 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
6055 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
6056 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
6057 (AT_PURE_LEX_IF): True if pure or push parser.
6059 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
6061 Document Yacc prologue alternatives and default %destructor's and
6062 %printer's as experimental. Don't mention Java yet. Discussed at

6086 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
6087 occurrence of each of %file-prefix and %output. Add check for %defines
6089 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
6090 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
6091 Remove the `=' from %output.
6093 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
6095 Don't escape $ in test case titles since Autoconf 2.61 now does that

6102 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
6104 Rename <!> to <>. Discussed starting at

6114 * tests/actions.at (Default tagless %printer and %destructor,
6115 Default tagged and per-type %printer and %destructor,
6116 Default %printer and %destructor are not for error or $undefined,
6117 Default %printer and %destructor are not for $accept,
6118 Default %printer and %destructor for mid-rule values): Update.
6119 * tests/input.at (Default %printer and %destructor redeclared,
6120 Unused values with default %destructor): Update.

6135 grammar is maintained with Bison's highest standards.
6136 * src/getargs.c: Fix some typos in Doxygen comments.

6140 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
6141 later. Reported by Paul Eggert in
6142 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
6143 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
6144 * src/scan-code.l (translate_action): Don't bother invoking
6145 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
6146 (code_scanner_free): Instead of invoking
6147 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

6155 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
6156 has been called previously for the same key.
6157 (muscle_find): Return storage instead of value so that
6158 --enable-gcc-warnings doesn't produce warnings that the return discards
6159 const. aver that the value and storage are the same since storage
6160 could potentially be NULL when value is not.
6161 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
6164 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6166 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
6167 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives

6178 since they are freed.
6179 * src/files.c: Likewise.

6182 (tr): Now operates in-place. All uses changed.

6186 read-only data in variables that will be freed.
6187 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
6188 src_extension, and header_extension.

6190 spec_verbose_file, spec_graph_file, spec_defines_file,
6191 parser_file_name, and dir_prefix.
6192 * src/getargs.c (getargs): Don't store read-only data in variables that
6194 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
6195 (which previously existed but was unused), and quotearg_free.
6196 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
6197 * src/muscle_tab.c: Likewise.
6198 (muscle_entry): Make the value char const *,
6199 and add a new storage member that is char * and can be freed.
6200 (muscle_entry_free): New private function.
6201 (muscle_init): Use it instead of free.
6202 (muscle_insert, muscle_grow): Update and use new storage member.
6203 (muscle_code_grow): Free the string passed to muscle_grow
6204 since it's not needed anymore.
6205 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
6206 add a new `char *code' member.
6207 ("{...}"): Declare semantic type as code.
6208 * src/scan-code.h (translate_rule_action):
6209 (translate_symbol_action, translate_code, translate_action): Return
6210 `char const *' rather than `char *' since external code should not free
6212 * src/scan-code.l: Likewise.
6213 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
6214 which is "{...}" in the parser.
6215 * tests/Makefile.am (maintainer-check-valgrind): Set
6216 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
6218 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
6220 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
6221 expecting a non-zero exit status sets --leak-check=summary and
6222 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
6223 this case, and we don't want to hear about it.

6241 the value is a set/used mid-rule value unless
6242 --warnings=midrule-values was specified.

6244 declarations): Run tests with and without --warnings=midrule-values.
6246 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
6247 than LIST_FREE directly.
6249 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

6268 empty subargument list. For example: `bison --warnings= parser.y'.
6270 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
6272 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
6273 the parser header file so that gcc doesn't warn.
6275 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
6277 Split the default %destructor/%printer into two kinds: <*> and <!>.

6318 * tests/input.at (Default %printer and %destructor redeclared): Extend.
6319 (Unused values with default %destructor): Extend.
6321 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
6323 Don't apply the default %destructor/%printer to an unreferenced midrule
6325 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
6326 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
6327 like $@n instead of just @n so that the default %destructor/%printer
6328 logic doesn't see them as user-defined symbols.
6329 (symbol_is_dummy): Check for both forms of the name.
6330 * src/reader.c (packgram): Remove the `$' from each midrule symbol
6331 name for which the midrule value is referenced in any action.
6332 * tests/actions.at (Default %printer and %destructor for mid-rule
6334 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
6335 for change to dummy symbol names.

6339 Warn about unset midrule $$ if the corresponding $n is used.
6340 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
6342 (packgram): Before invoking grammar_rule_check on any rule, make sure
6343 all actions have already been scanned in order to set `used' flags.
6344 Otherwise, checking that a midrule's $$ is set will not always work
6345 properly because the midrule check must forward-reference the midrule's
6347 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
6350 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
6352 More improvements to the documentation of the prologue alternatives:
6353 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
6355 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
6356 some text to clarify the relative importance of the new directives and
6357 to show how these directives may be viewed as code labels.
6359 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
6361 Similar to the recently removed %before-header, add %code-top as the
6362 alternative to the pre-prologue. Mentioned at
6363 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
6364 Also, let the prologue alternatives appear in the grammar section.
6365 * src/parse-gram.y (PERCENT_CODE_TOP): New token.

6417 Work also when the working directory (with e.g. coreutils sources)
6418 is version controlled with git, rather than CVS.
6419 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
6421 In messages and comments, say e.g., "checked-out sources",
6422 rather than "CVS sources".
6423 (version_controlled_file): New function. Work for git as well as
6424 for CVS. Don't use grep's -q option.
6425 (slurp): Call it here, in place of CVS-specific code.
6427 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
6429 Fix testsuite for ./configure --enable-gcc-warnings:
6430 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
6431 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
6432 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
6433 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.

6472 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
6474 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
6475 variable was sometimes used without being initialized. This
6476 messed up the installation of the INSTALL file in some cases.
6478 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
6480 * bootstrap (usage, main program, symlink_to_gnulib): Add option
6481 --copy. Inspired by a suggestion from Bruno Haible.
6483 2006-10-03 Jim Meyering <jim@meyering.net>
6485 * bootstrap: Undo last change to this file, since now gnulib-tool
6486 sticks with the automake default in generating dependencies.
6488 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
6490 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
6491 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
6493 * doc/bison.1: Add copyright notice.

6514 * src/print_graph.c: Include graphviz.h rather than vcg.h.
6515 (static_graph, fgraph): Remove. All uses changed to pass
6516 arguments instead of sharing a static var.
6517 (print_core, print_actions, print_state, print_graph):
6518 Output graphviz format rather than VCG format.
6519 * tests/.cvsignore: Remove *.vcg; add *.dot.
6520 * tests/output.at: Expect *.dot files, not *.vcg files.

6523 accommodates the 2006-10-08 change.
6525 2006-10-11 Bob Rossi <bob@brasko.net>
6527 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.

6535 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
6536 in a push parser. Reindent slightly to match yacc.c better.
6538 2006-10-11 Bob Rossi <bob@brasko.net>
6540 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
6542 (yypvarsinit, yypushparse): Remove init of removed fields.

6552 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
6553 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
6554 b4_define_user_cde and uses): Remove.
6555 (b4_comment, b4_prefix, b4_sync_start): New.
6556 * data/bison.m4: New file, with most of the content removed from c.m4.
6557 * src/muscle_tab.h: Use "do {...} while(0)" throughout.

6564 Fix test failure reported by Tom Lane in
6565 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
6566 and try to make such failures easier to catch in the future.
6567 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
6568 that's now the caller's responsibility.
6569 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
6570 Set yychar = YYEOF if it's negative.
6571 * tests/actions.at (yylex): Abort if asked to read past EOF.

6581 Fix problems with translating English-language diagnostics.
6582 * bootstrap: Fix bug introduced in recent bootstrap changes, with
6583 respect to bison-runtime pot generation. The YY_ stuff
6584 wasn't being captured.
6585 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
6586 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
6587 * runtime-po/POTFILES.in: Add data/push.c.
6589 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
6591 Merge bootstrap changes from coreutils.
6593 2006-09-28 Jim Meyering <jim@meyering.net>
6595 Automatically generated dependencies are important even
6596 when all of the sources in a directory come from gnulib.
6597 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
6598 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
6600 2006-09-23 Jim Meyering <jim@meyering.net>
6602 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
6604 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6606 * bootstrap: Add support for --force.
6607 (usage): New function. Describe usage less tersely.

6618 * data/push.c (yyresult_get): Remove function.
6619 (YYPUSH_MORE): Add #define.
6620 (yypushparse): Modify return value.
6622 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6624 * stamp-h.in: Remove; no longer needed.
6625 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
6626 Remove config.h, config.hin, intl (no longer created).
6627 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
6630 Sync bootstrap from coreutils, as follows:
6632 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
6634 * bootstrap (symlink_to_gnulib): New function.
6635 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
6636 to copies-of-gnulib.
6637 (cp_mark_as_generated, slurp, gnulib_files):
6638 Avoid making a copy if it's the same as the old version.
6639 (gnulib_files): Add support for this variable (used by Bison).
6641 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
6643 * src/getargs.c (usage): Rework to use conventions similar to
6644 coreutils, to make translation a bit easier and the code a bit
6645 smaller. Problem reported by Tim Van Holder.
6647 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
6649 Use some of gnulib's new modules, taken from coreutils.
6651 * bootstrap: Sync from coreutils, except add support for gnulib_files.
6652 * bootstrap.conf: New file.
6653 (gnulib_modules): Add configmake, inttypes, unistd.
6654 (XGETTEXT_OPTIONS): Add complain, complain_at,
6655 fatal, fatal_at, warn, warn_at, unexpected_end.
6656 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
6657 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
6659 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
6661 (GNULIB_AUTOCONF_SNIPPET): Remove.
6662 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
6664 * lib/.cvsignore: Add inttypes_.h.
6665 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
6666 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
6667 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
6668 no-longer-necessary initializations.
6669 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.

6671 use the unistd module.
6672 * src/system.h: Likewise.
6673 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,

6675 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
6676 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
6677 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
6678 * src/system.h: Include inttypes.h unconditionally, now that we
6679 use the inttypes module. Don't bother to include stdint.h, since
6680 inttypes.h now does that for us.
6681 (LOCALEDIR): Remove, now that we use the configmake module.
6682 * src/getargs.c: Include configmake.h.
6683 * src/main.c: Likewise.
6684 * src/output.c: Likewise.
6685 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
6686 not from $abs_top_builddir, since config.h moved.
6689 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
6690 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
6692 * src/parse-gram.y (symbol_declaration): Don't put statements
6693 before declarations; it's not portable to C89.
6694 * src/scan-code.l (handle_action_at): Likewise.
6696 * src/scan-code.l: Always initialize braces_level; the old code
6697 left it uninitialized and therefore had undefined behavior.
6699 Don't attempt to redefine 'assert', since it runs afoul of
6700 systems where standard headers (mistakenly) include <assert.h>.
6701 Instead, define and use our own alternative, called 'aver'.
6702 * src/reader.c: Don't include assert.h, since we no longer
6704 * src/scan-code.l: Likewise.
6705 * src/system.h (assert): Remove, replacing with....
6706 (aver): New function, taking a bool arg. All uses changed.
6707 * src/tables.c (pack_vector): Ensure that aver arg is bool,
6708 not merely an integer.
6710 2006-09-15 Bob Rossi <bob@brasko.net>
6712 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
6713 * data/c.m4 (YYPUSH): New.
6714 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
6715 * src/getargs.c (push_parser): New var.
6716 * src/getargs.h (push_parser): New declaration.
6717 * src/output.c (prepare): Add macro insertion of `push_flag'.
6718 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
6719 (prologue_declaration): Parse %push-parser.
6720 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
6721 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
6722 list of removed lines from the traces observed.
6723 (AT_CHECK_CALC_LALR): Added push parser tests.
6725 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
6727 * NEWS: Version 2.3a.
6728 * configure.ac (AC_INIT): Likewise.
6730 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
6731 "#define YYSTYPE int" that caused "make maintainer-check" to fail
6732 due to header ordering dependencies. I don't know why the #define
6735 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
6736 runtime cost when YYDEBUG is not defined, and so that some tests
6737 that used to fail now work. Problem and initial suggestion by
6739 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
6740 * data/glr.cc (b4_parser_class_name):
6741 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
6742 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
6743 (yydebug_) [YYDEBUG]: New member.
6744 (yycdebug_): Now defined only if YYDEBUG.
6745 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
6746 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
6747 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
6749 (debug_stream, set_debug_stream, debug_level, set_debug_level):
6750 Define only if YYDEBUG.
6751 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
6753 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
6754 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
6755 AT_CHECK_CALC_GLR_CC that are working now.
6757 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
6759 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
6760 We don't need them in glr.cc, and glr.c defines them.
6761 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
6762 assumes that defining it to anything is the same as defining
6763 it to 1. Problem reported by Paolo Bonzini.
6765 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
6767 * data/c.m4 (b4_null, b4_case): Define.
6768 * src/output.c (prepare_symbols): Use b4_null.
6769 (user_actions_output): Use b4_case.
6771 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
6773 * data/glr.c (b4_shared_declarations): Put start-header first,
6774 before any #includes that we generate, so that feature-test
6775 macros work. Problem reported by Michael Deutschmann in
6776 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
6777 * data/lalr1.cc: Likewise.
6778 * doc/bison.texinfo (Prologue): Document that feature-test macros
6779 should be defined before any Bison declarations.
6780 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
6781 that depend on location.hh after, not before, Bison decls, since
6782 we now include location.hh after the first user prologue.
6784 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
6785 Sander Brandenburg in
6786 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
6787 Also, fix minor white space and comment issues.
6788 (Prologue): Mention that it's better to define feature-test macros
6789 before Bison declarations. Problem reported by Michael Deutschmann.
6791 * README-cvs: Fix typo: "&" should be "&&". Problem reported
6793 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
6794 This adjusts to recent gnulib changes.
6796 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6798 Finish implementation of per-type %destructor/%printer. Discussed
6800 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
6802 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
6803 * NEWS (2.3+): Add a description of this feature to the default
6804 %destructor/%printer description.
6805 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
6806 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6807 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
6808 list node contains a semantic type.
6809 * src/symtab.c, src/symtab.h: Extend with a table that associates
6810 semantic types with their %destructor's and %printer's.
6811 (semantic_type_from_uniqstr, semantic_type_get,
6812 semantic_type_destructor_set, semantic_type_printer_set): New functions
6813 composing the public interface of that table.
6814 (symbol_destructor_get, symbol_destructor_location_get,
6815 symbol_printer_get, symbol_printer_location_get): If there's no
6816 per-symbol %destructor/%printer, look up the per-type before trying
6818 * tests/actions.at (Per-type %printer and %destructor): New test case.
6819 * tests/input.at (Default %printer and %destructor redeclared):
6820 Extend to check that multiple occurrences of %symbol-default in a
6821 single %destructor/%printer declaration is an error.
6822 (Per-type %printer and %destructor redeclared, Unused values with
6823 per-type %destructor): New test cases.
6825 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6827 Require default %destructor/%printer to be declared using
6828 %symbol-default instead of an empty symbol list, and start working on
6829 new per-type %destructor/%printer. Discussed at
6830 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
6831 * NEWS (2.3+): Add %symbol-default to example.
6832 * bison.texinfo (Freeing Discarded Symbols): Likewise.
6833 (Table of Symbols): Add entry for %symbol-default.
6834 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
6835 (generic_symlist, generic_symlist_item): New nonterminals for creating
6836 a list in which each item is a symbol, semantic type, or
6838 (grammar_declaration): Use generic_symlist in %destructor and %printer
6839 declarations instead of symbols.1 or an empty list.
6840 (symbol_declaration, precedence_declaration, symbols.1): Update actions
6841 for changes to symbol_list.
6842 * src/reader.c: Update for changes to symbol_list.
6843 * src/scan-code.l: Likewise.
6844 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
6845 * src/symlist.c, src/symlist.h: Extend such that a list node may
6846 represent a semantic type or a %symbol-default in addition to just an
6847 ordinary symbol. Add switched functions for setting %destructor's and
6849 * tests/actions.at, tests/input.at: Add %symbol-default to all default
6850 %destructor/%printer declarations.
6852 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
6854 Whether the default %destructor/%printer applies to a particular symbol
6855 isn't a question of whether the user *declares* that symbol (in %token,
6856 for example). It's a question of whether the user by any means
6857 *defines* the symbol at all (by simply using a char token, for
6858 example). $end is defined by Bison whereas any other token with token
6859 number 0 is defined by the user. The error token is always defined by
6860 Bison regardless of whether the user declares it with %token, but we
6861 may one day let the user define error as a nonterminal instead.
6862 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6863 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
6864 the meaning of "user-defined".
6865 * tests/actions.at (Default %printer and %destructor for user-declared
6866 end token): Rename to...
6867 (Default %printer and %destructor for user-defined end token): ...
6870 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
6871 computation of whether to apply the default, don't maintain a list of
6872 every Bison-defined symbol. Instead, just check for a first character
6873 of '$', which a user symbol cannot have, and check for the error token.
6875 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
6877 Don't apply the default %destructor or %printer to the error token,
6878 $undefined, or $accept. This change fits the general rule that the
6879 default %destructor and %printer are only for user-declared symbols,
6880 and it solves several difficulties that are described in the new test
6882 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
6883 * tests/actions.at (Default %printer and %destructor are not for error
6884 or $undefined, Default %printer and %destructor are not for $accept):
6887 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
6889 Allow %start after the first rule.
6890 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
6891 when parsing the first rule.
6892 (check_and_convert_grammar): Search for it here after all grammar
6893 declarations have been parsed. Skip midrules, which have dummy LHS
6895 * src/symtab.c (symbol_is_dummy): New function.
6896 * src/symtab.h (symbol_is_dummy): Declare it.
6897 * tests/input.at (%start after first rule): New test.
6899 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6901 Redo some of the previous commit: add back the ability to use
6902 non-aliased/undeclared string literals since it might be useful to
6903 those declaring %token-table.
6904 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6905 commit: don't worry about complaints from symbols_pack.
6906 * src/symtab.c (symbol_new, symbol_class_set,
6907 symbol_check_alias_consistency): Undo changes in previous commit: count
6908 each string literal as a new symbol and token, assign it a symbol
6909 number, and don't complain about non-aliased string literals.
6910 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6911 and token counts but does still set aliased tokens to the same number,
6912 symbol_pack_processor now leaves empty slots in the symbols array.
6914 * tests/regression.at (Undeclared string literal): Remove test case
6915 added in previous commit since non-aliased string literals are allowed
6917 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6918 remove unnecessary string literal declarations.
6919 * tests/sets.at (Firsts): Likewise.
6921 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6923 Don't allow an undeclared string literal, but allow a string literal to
6924 be used before its declaration.
6925 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6926 symbols_pack complained.
6927 * src/symtab.c (symbol_new): Don't count a string literal as a new
6929 (symbol_class_set): Don't count a string literal as a new token, and
6930 don't assign it a symbol number since symbol_make_alias does that.
6931 (symbol_make_alias): It's not necessary to decrement the symbol and
6932 token counts anymore. Don't assume that an alias declaration occurs
6933 before any uses of the identifier or string, and thus don't assert that
6934 one of them has the highest symbol number so far.
6935 (symbol_check_alias_consistency): Complain if there's a string literal
6936 that wasn't declared as an alias.
6937 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6938 symbol_pack asserts that every token has been assigned a symbol number
6939 although undeclared string literals have not.
6940 * tests/regression.at (String alias declared after use, Undeclared
6941 string literal): New test cases.
6942 (Characters Escapes, Web2c Actions): Declare string literals as
6944 * tests/sets.at (Firsts): Likewise.
6946 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6948 In the grammar scanner, STRING_FINISH unclosed constructs and return
6949 them to the parser in order to improve error messages.
6950 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6951 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6952 * tests/input.at (Unclosed constructs): New test case.
6953 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6956 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6959 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6961 Handle string aliases for character tokens correctly.
6962 * src/symtab.c (symbol_user_token_number_set): If the token has an
6963 alias, check and set its alias's user token number instead of its own,
6964 which is set to indicate the alias. Previously, every occurrence of
6965 the character token in the grammar overwrote that alias indicator with
6967 * tests/input.at (String aliases for character tokens): New test.
6969 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6971 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6973 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6975 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6976 to prevent failures when building on older platforms.
6977 Check for autopoint failure.
6978 Set XGETTEXT_OPTIONS to values that check for C format strings,
6979 so that translators are warned about them (this also helps
6980 prevent core dumps).
6982 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6983 function, since it simplifies our code a bit.
6985 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6986 rather than -W, so we don't get bogus warnings about sign comparisons.
6987 Add -Wpointer-arith, since that warning is useful (it reports code
6988 that does not conform to C89 and that some compilers reject).
6989 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6990 since it's no longer needed.
6992 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6994 Clean up scanners a bit.
6995 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6996 definitions so gcc won't warn when obstack_for_string is unused.
6997 * src/scan-code.l: config.h and system.h are already #include'd by
6998 scan-code-c.c, so get rid of them here.
6999 * src/scan-gram.l: Likewise.
7000 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
7001 definitions rather than duplicating the rest of it.
7002 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
7004 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
7006 Suppress signed/unsigned comparison warnings for yycheck.
7007 * data/c.m4 (b4_safest_int_type): New macro.
7008 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
7009 a signed int type, cast it to b4_safest_int_type first.
7010 * data/yacc.c: Likewise.
7011 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
7014 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
7016 * doc/bison.texinfo: Fix some typos.
7018 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
7020 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
7021 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
7023 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
7024 the latest gnulib does this a different way.
7025 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
7026 translation was patched, so stop omitting it.
7028 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
7030 Enable declaration of default %printer/%destructor. Make the parser
7031 use these for all user-declared grammar symbols for which the user does
7032 not declare a specific %printer/%destructor. Thus, the parser uses it
7033 for token 0 if the user declares it but not if Bison generates it as
7034 $end. Discussed starting at
7035 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
7036 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
7038 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
7039 * NEWS (2.3+): Mention.
7040 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
7041 declare a %destructor for a mid-rule's semantic value. It's just
7042 impossible to declare one specific to it.
7043 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
7044 code. Describe default %destructor form.
7045 * src/parse-gram.y (grammar_declaration): Parse default
7046 %printer/%destructor declarations.
7047 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
7048 and symbol_destructor_location_get rather than accessing the destructor
7049 and destructor_location members of struct symbol.
7050 (symbol_printers_output): Likewise but for %printer's.
7051 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
7053 * src/symtab.c (default_destructor, default_destructor_location,
7054 default_printer, default_printer_location): New static global
7055 variables to record the default %destructor and %printer.
7056 (symbol_destructor_get, symbol_destructor_location_get,
7057 symbol_printer_get, symbol_printer_location_get): New functions to
7058 compute the appropriate %destructor and %printer for a symbol.
7059 (default_destructor_set, default_printer_set): New functions to set the
7060 default %destructor and %printer.
7061 * src/symtab.h: Prototype all those new functions.
7062 * tests/actions.at (Default %printer and %destructor): New test to
7063 check that the right %printer and %destructor are called, that they're
7064 not called for $end, and that $$ and @$ work correctly.
7065 (Default %printer and %destructor for user-declared end token): New
7066 test to check that the default %printer and %destructor are called for
7067 a user-declared end token.
7068 * tests/input.at (Default %printer and %destructor redeclared, Unused
7069 values with default %destructor): New tests to check related grammar
7070 warnings and errors.
7072 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
7074 Clean up handling of %destructor for the end token (token 0).
7075 Discussed starting at
7076 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
7078 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
7080 Make the skeletons consistent in how they pop the end token and invoke
7082 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
7083 state, which has token number 0, since this would invoke the
7084 %destructor for the end token.
7085 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
7086 until after shifting the end token, or else it won't be popped.
7087 * data/yacc.c (yyparse): Likewise.
7089 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
7090 it's the end token. Upon termination, destroy an unshifted lookahead
7091 even when it's the end token.
7092 * data/lalr1.cc (yy::parser::parse): Likewise.
7093 * data/yacc.c (yyparse): Likewise.
7095 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
7096 value warnings for the end token when the user gives the end token a
7099 * tests/actions.at (Printers and Destructors): Test all the above.
7101 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
7103 Update to latest gnulib and gettext versions.
7104 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
7106 (gnulib_files): Add m4/warning.m4. Don't worry about files
7107 overwritten by autopoint.
7108 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
7109 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
7111 Don't use autoreconf; instead, invoke autopoint etc. by hand,
7112 so that we can remove the intl files at a better time.
7113 (intl_files_to_remove): Remove aclocal.m4, since it gets
7114 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
7115 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
7116 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
7117 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
7118 Remove datarootdir hack; no longer needed.
7119 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
7120 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
7121 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
7123 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
7124 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
7126 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7128 * bootstrap: Adjust to today's change to gnulib-tool by invoking
7129 it with --assume-autoconf='latest-stable'.
7131 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
7133 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
7134 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
7136 * src/muscle_tab.h (muscle_grow): Replace the header comments with
7137 those from muscle_tab.c since the old ones are misleading.
7139 2006-07-13 Akim Demaille <akim@epita.fr>
7141 Support %define "KEY" {VALUE}.
7142 * src/scan-code.h, src/scan-code.l (translate_action)
7143 (translate_rule_action, translate_symbol_action, translate_code):
7144 Return char *, not const char *.
7145 * src/parse-gram.y (declaration): Rename as...
7146 (prologue_declaration): this.
7147 (string_content): Remove this nonterminal, use STRING.
7148 (braceless, content, content.opt): New nonterminal.
7150 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
7152 * src/scan-gram.l (getargs.h): Don't include it.
7154 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
7156 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
7157 rather than a for-loop that declares a local bool variable. This
7158 should work around a compatibility problem with a Cray x1e C++
7159 compiler reported by Hung Nguyen in
7160 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
7161 The for-loop was introduced in the 2004-11-17 change but I don't
7162 know why it was needed.
7164 2006-07-12 Akim Demaille <akim@epita.fr>
7166 * data/c.m4: Comment changes.
7168 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
7170 * src/complain.c (error_message, ERROR_MESSAGE): New.
7172 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
7173 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
7175 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
7177 * NEWS: Instead of %union, you can define and use your own union type
7178 YYSTYPE if your grammar contains at least one <type> tag.
7179 Your YYSTYPE need not be a macro; it can be a typedef.
7180 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
7181 (Union Decl, Decl Summary): Document this.
7182 * data/glr.c (YYSTYPE): Implement this.
7183 * data/glr.cc (YYSTYPE): Likewise.
7184 * data/lalr1.cc (YYSTYPE): Likewise.
7185 * data/yacc.c (YYSTYPE): Likewise.
7186 * src/output.c (prepare): Output tag_seen_flag.
7187 * src/parse-gram.y (declaration, grammar_declaration):
7188 Use 'union_seen' rather than 'typed' to determine whether
7189 %union has been seen, since grammars can now be typed without
7191 (symbol_declaration, type.opt, symbol_def):
7192 Keep track of whether a tag has been seen.
7193 * src/reader.c (union_seen, tag_seen): New vars.
7195 * src/reader.h (union_seen, tag_seen, typed): Likewise.
7196 * src/scan-code.l (untyped_var_seen): New variable.
7197 (handle_action_dollar): Adjust to above changes.
7198 (handle_action_dollar, handle_action_at):
7199 Improve overflow checking for outlandish numbers.
7200 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
7201 avoid new diagnostics generated by above changes.
7202 * tests/regression.at (YYSTYPE typedef): Add test to check
7203 for type tags without %union.
7205 * src/symlist.c (symbol_list_length): Return int, not unsigned
7206 int, since callers expect int. This may need to get revisited
7207 once we have proper integer overflow checking.
7209 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
7210 object is now static.
7212 * src/getargs.c (flags_argmatch): Return void, not int,
7213 to pacify ./configure --enable-gcc-warnings.
7215 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
7216 since last_string is already defined to FLEX_PREFIX (last_string).
7218 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
7220 Implement --warnings/-W.
7221 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
7223 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
7225 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
7226 (warnings_args, warnings_types): New.
7227 (getargs, short_options, long_options): Accept -W/--warnings.
7228 Sort the options by alphabetical order, upper case letter right
7229 before its lower case.
7231 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
7233 Change %merge result type clash warnings to errors. Discussed at
7234 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
7235 * src/reader.c (record_merge_function_type): Use complain_at.
7236 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7237 declared later): Update test case results.
7239 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
7241 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
7242 to be in alphabetical order.
7243 (trace_args): Spelling fixes.
7245 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
7247 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
7248 so they don't collide with user-defined macros.
7249 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
7250 this was never guaranteed, and now that we're using gnulib stdint,
7251 which defines int_fast16_t to long int, the problem is exposed.
7253 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
7255 * data/c.m4 (b4_basename): Simplify a bit, since we don't
7256 need the full POSIX semantics (and weren't implementing them
7259 Adjust to Autoconf 2.60 and today's gnulib.
7260 * bootstrap (gnulib_modules): Add stdint.
7261 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
7262 no longer copies it.
7263 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
7264 since stdint needs the former and wcwidth (which is now required
7265 by mbswidth) needs the latter.
7266 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
7267 work around a compatibility glitch between gettext 0.14.6 and
7269 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
7270 Do not check for uintptr_t, since new stdint module does the right
7272 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
7273 Add stdint.h, stdint_.h, wcwidth.h.
7274 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
7275 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
7276 stdint.m4, wchar_t.m4, wcwidth.m4.
7277 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
7278 usual order for ../lib/*.h files.
7279 (file_name_split): Use last_component, not base_name, to adjust
7281 * src/parse-gram.h: Include <strverscmp.h> in the usual order
7282 for ../lib/*.h files.
7283 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
7284 Define unconditionally, since we now assume the stdint module.
7285 * src/scan-skel.l: Include <dirname.h>.
7286 (BASE_QPUTS): Use last_component, not base_name.
7287 * src/system.h: Include <unlocked-io.h> in the usual order
7288 for ../lib/*.h files. Include <stdint.h> unconditionally,
7289 since we now use the stdint module.
7290 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
7291 HAVE_UINTPTR_T, since we now use the stdint module.
7292 (base_name): Remove decl, since files now include <dirname.h>
7295 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
7297 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
7299 * data/yacc.c, data/glr.c, data/location.cc: Use them.
7300 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
7302 * tests/calc.at: Adjust.
7304 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
7306 * data/c.m4 (b4_basename): New.
7307 (b4_syncline): Also output the location of its invocation (from
7309 (b4_user_action, b4_define_user_action, b4_user_actions)
7310 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
7311 (b4_user_stype): New.
7312 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
7314 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
7316 In the grammar file, the first column is 1 not 0 on the first line as
7317 on every other line.
7318 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
7319 * tests/input.at (Torturing the Scanner): Update output.
7321 * src/scan-gram.l (scanner_cursor): Declare it static.
7323 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
7325 In warnings, say "previous declaration" rather than "first
7327 * src/symtab.c (redeclaration): Do that here.
7328 * src/reader.c (record_merge_function_type): In the case of a result
7329 type clash, report the previous declaration rather than the very first
7330 one in the grammar file.
7331 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7332 declared later): Add a third declaration to check this behavior.
7333 * tests/input.at (Incompatible Aliases): Update output.
7335 2006-06-27 Akim Demaille <akim@epita.fr>
7337 * doc/Doxyfile.in: New.
7338 * doc/Makefile.am: Use it.
7339 * src/lalr.h, src/symtab.h: Initial doxygenation.
7341 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7343 Don't miss %merge result type warnings just because the LHS types are
7344 declared after the %merge. This continues the effort of the previous
7346 * src/reader.c (get_merge_function): Don't set the merger type yet.
7347 (record_merge_function_type): New function for setting the merger type
7348 and checking for clashes.
7349 (grammar_current_rule_merge_set): Set the location of the %merge for
7351 (packgram): Invoke record_merge_function_type for each rule now that
7352 all symbol type declarations have been parsed.
7353 * src/reader.h (merger_list.type_declaration_location): New member
7354 storing the location of the first %merge from which the type for this
7355 merging function was derived.
7356 * src/symlist.h (symbol_list.merger_declaration_location): New member
7357 storing the location of a rule's %merge, if any.
7358 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
7359 declared later): New test to catch the error fixed by the above patch.
7361 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7363 Get action warnings (grammar_rule_check) right even when symbol
7364 declarations appear after the rules. Discussed at
7365 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
7367 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
7368 Don't mistake the type of $$ in a midrule to be that of its parent
7370 * src/reader.c (grammar_current_rule_end): Don't invoke
7371 grammar_rule_check yet since not all symbol declarations may have been
7373 (grammar_midrule_action): Likewise.
7374 Don't record whether the midrule's $$ has been used yet since actions
7375 haven't been translated yet.
7376 Record the midrule's parent rule and its RHS index within the parent
7378 (grammar_current_rule_action_append): Don't translate the action yet
7379 since not all symbol declarations may have been parsed yet and, thus,
7380 warnings about types for $$, $n, @$, and @n can't be reported yet.
7381 (packgram): Translate the action and invoke grammar_rule_check now that
7382 all symbol declarations have been parsed.
7383 * src/scan-code.l (handle_action_dollar): Now that this is invoked
7384 after parsing the entire grammar file, the symbol list here in the case
7385 of a midrule is actually the midrule's empty RHS, so reference its
7386 parent rule's RHS where necessary.
7387 On the other hand, now that you can already know it's a midrule, you
7388 aren't forced to think $$ has the same type as its parent rule's $$.
7389 (handle_action_at): In the case of a midrule, reference the parent rule
7391 * src/symlist.c (symbol_list_new): Initialize new midrule-related
7393 (symbol_list_length): Now that this is invoked after all rules have
7394 been parsed, a NULL symbol (rather than a NULL symbol list node)
7395 terminates a rule. symbol_list_print already does this correctly.
7396 * src/symlist.h (symbol_list.midrule_parent_rule,
7397 symbol_list.midrule_parent_rhs_index): New members so that midrules can
7398 remember their relationships with their parents.
7399 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
7400 fixed by the above patch.
7401 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
7403 (Unused values): ... this old test case and...
7404 (Unused values before symbol declarations): ... this new test case.
7405 This one is the same as `Unused values' except that all symbol
7406 declarations appear after the rules in order to catch the rest of the
7407 errors fixed by the above patch.
7409 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
7412 * src/reader.c (current_rule): Declare it static since it's no longer
7413 used outside this file.
7414 (grammar_current_rule_action_append): Remove redundant arguments from
7415 translate_rule_action invocation.
7416 * src/reader.h (current_rule): Remove this unused extern.
7417 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
7418 * src/scan-code.l (translate_rule_action): Likewise.
7420 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
7422 Clean up yesterday's patch.
7423 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
7425 * src/reader.c (grammar_current_rule_action_append): ... here for
7426 consistency with grammar_current_rule_symbol_append.
7427 * tests/regression.at (Braced code in declaration in rules section):
7428 Make yyerror and yylex static as usual.
7430 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
7432 Fix bug that mistakes braced code in a declaration in the rules section
7433 to be a rule action. Mentioned at
7434 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
7435 * src/scan-gram.l: Move midrule action detection from the start of the
7436 scanning of any braced code to...
7437 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
7438 action. For readability, use $2 and @2 rather than the equivalent
7440 * tests/regression.at (Braced code in declaration in rules section):
7441 New test to catch the error fixed by the above patch.
7443 Work on code readability some.
7444 * src/scan-code.l (current_rule): Get rid of this misleading and
7445 redundant declaration: it's actually extern'ed in reader.h.
7446 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
7447 translate_action): Add a rule argument and use it instead of the global
7449 (translate_rule_action): This already receives current_rule through an
7450 argument, so pass it on to translate_action instead of assigning
7451 current_rule to current_rule.
7452 (translate_symbol_action, translate_code): Pass rule = NULL to
7455 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
7457 Rename %before-definitions to %start-header and %after-definitions to
7458 %end-header. Don't use these declarations to separate pre-prologue
7459 blocks from post-prologue blocks. Add new order-independent
7460 declarations %before-header and %after-header as alternatives to the
7461 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
7462 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
7463 * NEWS (2.3+): Update for these changes.
7464 * data/glr.c (b4_before_definitions): Update to...
7465 (b4_start_header): ... this.
7466 (b4_after_definitions): Update to...
7467 (b4_end_header): ... this.
7468 * data/glr.cc: Likewise.
7469 * data/lalr1.cc: Likewise.
7470 * data/yacc.c: Likewise.
7471 * doc/bison.texinfo (The prologue): Update names, and replace remaining
7472 prologue blocks with %*-header declarations.
7473 (Calc++ Parser): Likewise.
7474 (Decl Summary): Update names.
7475 (Table of Symbols): Update description.
7476 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
7477 (PERCENT_END_HEADER): ... this.
7478 (PERCENT_BEFORE_DEFINITIONS): Update to...
7479 (PERCENT_START_HEADER): ... this.
7480 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
7481 (declaration): Update token names and m4 macro names.
7482 When parsing %end-header and %start-header, invoke translate_code
7483 before muscle_code_grow, and no longer set global booleans to remember
7484 whether these declarations have been seen.
7485 Parse new %after-header and %before-header.
7486 * src/reader.c (before_definitions, after_definitions): Remove.
7487 (prologue_augment): Accept a new bool argument to specify whether to
7488 augment the pre-prologue or post-prologue.
7489 * src/reader.h (before_definitions, after_definitions): Remove these
7491 (prologue_augment): Add new bool argument.
7492 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
7493 (PERCENT_END_HEADER): ... this.
7494 (PERCENT_BEFORE_DEFINITIONS): Update to...
7495 (PERCENT_START_HEADER): ... this.
7496 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
7497 * tests/actions.at (Printers and Destructors): Update names.
7499 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
7501 Add comparison operators for C++ location classes. Discussed at
7502 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
7503 * data/c++.m4 (b4_define_location_comparison): New boolean %define
7504 declaration indicating whether filename_type has an operator==. If
7505 filename_type is `std::string', it defaults to `1', `0' otherwise.
7506 * data/location.cc: Iff b4_define_location_comparison is `1', add
7507 operator== and operator!= for class position and for class location.
7510 * src/scan-action.l: Remove unused file.
7511 * src/symtab.c (symbol_printer_set): Use printer_location not
7512 destructor_location.
7513 * src/symtab.h (struct symbol): Replace incorrect source comment for
7515 * tests/input.at (Incompatible Aliases): Update output with correct
7518 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
7520 Don't put the pre-prologue in the header file. For the yacc.c code
7521 file and the glr.c header and code files, move the pre-prologue before
7522 the token definitions. Add new %before-definitions and
7523 %after-definitions to declare code that will go in both the header file
7524 and code file. Discussed at
7525 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
7526 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
7528 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
7529 * NEWS (2.3+): Describe these changes.
7530 * data/glr.c (b4_pre_prologue): Move from within to before...
7531 (b4_shared_declarations): ... this.
7532 Add new b4_before_definitions before b4_token_enums.
7533 Add new b4_after_definitions at the end.
7534 * data/glr.cc (b4_pre_prologue): Replace with...
7535 (b4_before_definitions): ... this in the header file.
7536 (b4_after_definitions): New near the end of the header file.
7537 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
7538 code file right before including the header file.
7539 (b4_before_definitions): New in the previous position of
7540 b4_pre_prologue in the header file.
7541 (b4_after_definitions): New near the end of the header file.
7542 * data/yacc.c: Clean up some m4 quoting especially in the header file.
7543 (b4_token_enums_defines): In the code file, move to right before
7544 YYSTYPE for consistency with the header file.
7545 (b4_before_definitions): New right before b4_token_enums_defines in
7546 both the header and code file.
7547 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
7548 header and code file.
7549 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
7550 of prologues for %union dependencies.
7551 (Decl Summary): In %defines description, mention the effect of
7552 %before-definitions and %after-definitions on the header file.
7553 (Calc++ Parser): Forward declare driver in a %before-definitions rather
7554 than in the pre-prologue so that make check succeeds.
7555 (Table of Symbols): Add entries for %before-definitions and
7557 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
7558 %before-definitions.
7559 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
7560 (declaration): Parse those declarations and append to
7561 b4_before_definitions and b4_after_definitions, respectively.
7562 * src/reader.c (before_definitions, after_definitions): New bools to
7563 track whether those declarations have been seen.
7564 (prologue_augment): Add to the post-prologue if %union,
7565 %before-definitions, or %after-definitions has been seen.
7566 * src/reader.h (before_definitions, after_definitions): New extern's.
7567 * src/scan-gram.l: Scan the new declarations.
7568 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
7569 prologue block in a %before-definitions or a %after-definitions based
7570 on whether the %union is declared.
7571 * tests/regression.at (Early token definitions with --yacc, Early token
7572 definitions without --yacc): Move tests for token definitions into the
7573 post-prologue since token names are no longer defined in the
7576 2006-06-20 Akim Demaille <akim@epita.fr>
7578 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
7579 (symbol_get): Use it.
7580 * src/parse-gram.y: Use it.
7582 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
7584 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
7585 build succeeds when configured with --enable-gcc-warnings.
7587 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7589 * src/parse-gram.y (char_name): New function.
7590 (CHAR, STRING, string_content): For %printer, properly escape.
7591 (ID): Prefer fputs to fprintf.
7592 (id): Reindent to be consistent with other rules.
7593 Properly quote char.
7595 The Translation Project changed its way of publishing translations
7596 to maintainers. I haven't received any responses to my request
7597 for supporting the old way, or for documenting the new way. I
7598 have modified 'bootstrap' to use screen scraping
7599 (in this case, HTML scraping). This is unreliable and inelegant,
7600 but I don't see any better way. Yuck.
7601 * bootstrap (TP_URL, WGET_COMMAND): New vars.
7602 (get_translations): New function, which uses HTML scraping to
7603 deduce locations of latest translations.
7604 Use this function to grab both bison and bison-runtime .po files.
7605 Don't bother priming the pump for the runtime-po domain any more,
7606 as it's now translated better than bison is.
7608 2006-06-19 Akim Demaille <akim@epita.fr>
7610 * src/scan-gram.l: No longer "parse" things after `%union' until
7611 `{'. Rather, return a single "%union" token.
7612 No longer make symbols: return strings, and leave the conversion
7613 to symbols to the parser.
7614 (SC_PRE_CODE, token_type): Remove.
7615 * src/parse-gram.y (%union): New field `character'.
7618 (ID, ID_COLON): Now that the scanner no longer makes them
7619 identifiers, adjust all uses to invoke symbol_get.
7620 (id_colon): New, wraps the conversion from string to symbol.
7621 (%union): Accept a possible union_name.
7622 (symbol): Now can be a char.
7623 * data/c.m4 (b4_union_name): Leave a default value.
7624 * data/glr.c, data/yacc.c: Use it.
7626 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
7628 For associating token numbers with token names for "yacc.c", don't use
7629 #define statements unless `--yacc' is specified; always use enum
7630 yytokentype. Most important discussions start at:
7631 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
7632 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
7634 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
7635 * NEWS (2.3+): Mention.
7636 * data/c.m4 (b4_yacc_if): New.
7637 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
7639 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
7640 on token name definitions.
7641 * src/getargs.c (usage): Capitalize `Yacc' in English.
7642 * src/output.c (prepare): Define b4_yacc_flag.
7643 * tests/regression.at (Early token definitions): Test that tokens names
7644 are defined before the pre-prologue not just before the post-prologue.
7645 Remove this test case and copy to...
7646 (Early token definitions with --yacc): ... this to test #define's.
7647 (Early token definitions without --yacc): ... and this to test enums.

7651 * NEWS: Reword the post-2.3 change to not be so optimistic about
7652 removing the old "look-ahead" spelling.
7653 Update previous look-ahead/lookahead change reports.

7736 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7738 * TODO: Add request from Nelson H. F. Beebe to be able to install
7739 Bison without installing the yacc script.
7741 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
7743 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
7744 and yytext if they're already #define'd.
7745 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
7746 * src/scan-code-c.c: ... here.
7747 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include

7752 Get Bison to build again when configured with --enable-gcc-warnings.
7753 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
7755 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
7756 loc argument as it shadows a global.
7757 * src/scan-gram.l: Remove stray comma that prevents boundary_set
7760 * src/.cvsignore: Add scan-code.c.
7762 2006-06-07 Akim Demaille <akim@epita.fr>
7764 * src/scan-gram.l: Move the "add a trailing ; to actions" code
7766 * src/scan-code.l: here.

7770 2006-06-07 Akim Demaille <akim@epita.fr>
7772 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
7774 2006-06-06 Akim Demaille <akim@epita.fr>
7776 Extract the parsing of user actions from the grammar scanner.
7777 As a consequence, the relation between the grammar scanner and
7778 parser is much simpler. We can also split "composite tokens" back
7780 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
7781 * src/scan-gram.l (add_column_width, adjust_location): Move to and
7783 * src/location.h, src/location.c (add_column_width)
7784 (location_compute): these.
7785 Fix the column count: the initial column is 0.
7786 (location_print): Be robust to ending column being 0.
7787 * src/location.h (boundary_set): New.
7788 * src/main.c: Adjust to scanner_free being renamed as
7790 * src/output.c: Include scan-code.h.
7791 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
7793 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)

7797 Whereever actions with $ and @ are used, use translate_code.
7798 (action): Remove this nonterminal which is now useless.
7799 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
7800 (grammar_current_rule_action_append): Use translate_code.

7810 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7811 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7812 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

7818 (increment_rule_length): Remove.
7819 (last_braced_code_loc): Rename as...
7820 (gram_last_braced_code_loc): this.
7821 Adjust to the changes of the parser.
7822 Move all the handling of $ and @ into...
7823 * src/scan-code.l: here.
7824 * src/scan-gram.l (handle_dollar, handle_at): Remove.

7837 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7839 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7840 Use Akim's wording from
7841 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
7843 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7845 Between Bison releases, manually append `+' to the previous Bison
7846 release number, and use that as a signal to automatically print the
7847 ChangeLog's CVS Id keyword from --version. Discussed starting at
7848 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
7849 * ChangeLog: Add Id header.
7850 * configure.ac (AC_INIT): Append `+' to `2.3'.
7851 * src/.cvsignore: Add revision.c.
7852 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
7853 (BUILT_SOURCES): Add revision.c.
7854 (revision.c): New target rule. This file defines a new global variable
7855 named revision. It initializes it with either the Id from ChangeLog
7856 or, if VERSION doesn't contain `+', with the empty string.
7857 * src/getargs.c (version): Print the value of revision.
7858 * src/revision.h: Extern revision.
7860 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7862 * NEWS: Version 2.3.
7863 * configure.ac (AC_INIT): Likewise.
7865 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7867 * data/glr.c (YYRECOVERING): Define to be a function-like macro
7868 with no arguments, not as an object-like macro. This is for
7869 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
7870 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
7871 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
7874 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
7876 * src/getargs.c (usage): Back out yesterday's modification of the
7877 --help output so that we don't have to wait for translation before
7880 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7882 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
7883 Problem reported by Akim Demaille.
7885 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
7887 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7889 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7891 * data/yacc.c (yy_reduce_print): Omit trailing white space in
7892 generated source code. Problem reported by Frans Englich in
7893 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7895 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7897 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7898 shell, not within 'make', so that 'make' by an ordinary builder
7899 (using GNU make) does not worry about configuring gzip. This also
7900 works around a bug reported independently by Keith Thompson and by
7901 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7902 stderr rather than stdout, messing up the build logs.
7904 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7906 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7907 to make sure that YYID will never be unused. This fixes a 'make
7908 maintainer-check' failure caused by the recent changes to the 'Trivial
7909 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7911 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7913 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7915 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7916 state before an empty RHS is always resolved here. Only the location
7917 of that state is guaranteed to be resolved, and that's enough. This
7918 fixes the remaining bug reported by Derek M. Jones in
7919 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7920 * tests/glr-regression.at (Uninitialized location when reporting
7921 ambiguity): Test the above case.
7922 Also, the embedded comments in this test case claim it checks the case
7923 of an empty RHS that has inherited the initial location. However, the
7924 corresponding LHS was already resolved, so yyresolveLocations didn't
7925 actually have reason to modify it. Fix this by forcing
7926 nondeterministic operation at the beginning of the parse.
7928 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7930 * data/c.m4 (b4_yy_symbol_print_generate):
7931 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7932 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7933 of the bugs reported today by Derek M Jones in
7934 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7935 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7936 defined to be a type name without parens or brackets.
7937 (Location Type): Similarly for YYLTYPE.
7938 * tests/regression.at (Trivial grammars): Put in a test for this
7939 bug that will be caught by 'make maintainer-check' (though not,
7940 alas, by 'make check' unless your compiler is picky).
7942 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
7944 * NEWS: Version 2.2.
7945 * configure.ac (AC_INIT): Likewise.
7947 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
7949 * data/glr.c (yyreportTree): Make room in yystates for the state
7950 preceding the RHS. This fixes the segmentation fault reported by Derek
7952 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7953 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7954 to the user. Reported for yyreportTree by Derek M. Jones later in the
7956 * THANKS: Add Derek M. Jones.
7957 Update my email address.
7958 Fix typo in Steve Murphy's name.
7960 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7962 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7963 checking against YYLAST that caused the parser to miss a potential
7964 alternative in its diagnostic.
7965 Problem reported by Maria Jose Moron Fernandez in
7966 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
7967 * data/lalr1.cc (yysyntax_error_): Likewise.
7968 * data/yacc.c (yysyntax_error): Likewise.
7969 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7970 tokens, in case we run into an older C compiler.
7971 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7972 Use them to check for the off-by-one error fixed above.
7974 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7975 YYSIZE_T, not size_t.
7976 * tests/regression.at (Trivial grammars): New test, to catch
7977 the error fixed by the above patch.
7979 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7981 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7983 Reported by Steve Murphy.
7985 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7987 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7988 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7990 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7992 Implement --trace=m4.
7993 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7994 * src/output.c (output_skeleton): When set, pass -dV to m4.
7996 Factor the handling of flags in m4.
7997 * src/output.c (prepare): Rename the muscle names debug, defines,
7998 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7999 * data/c.m4: Adjust.
8000 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
8001 Use b4_define_flag_if to define other b4_FLAG_if macros.
8002 (b4_location_if): As a consequence, rename as...
8003 (b4_locations_if): this, for consistency.
8004 Adjust all the skeletons.
8006 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8008 * etc/bench.pm: Shorten bench names.
8010 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8012 * src/output.h, src/output.c (error_verbose): Move to...
8013 * src/getargs.h, src/getargs.c: here.
8015 Adjust dependencies.
8017 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8019 * data/c.m4 (b4_copyright): Put the special exception for Bison
8020 skeletons here, so we don't have to put it in each skeleton. All
8021 uses changed. Suggested by Akim Demaille. Also, wrap the
8022 copyright notice, in case it is longer than 80 columns. Replace
8023 comma by newline after title.
8025 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8027 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
8028 incompatibility, not a bug. Mention that it wasn't fixed as of
8031 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
8033 * examples/extexi: Enforce the precedence of concatenation over
8035 Reported by Tommy Nordgren.
8037 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
8039 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
8040 with the member "token".
8041 Reported by Martin Nylin.
8043 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
8045 * data/glr.c: Switch to Bison 2.2 special-exception language in
8046 the copyright notice. Use more-regular format for titles and
8048 * data/glr.cc: Likewise.
8049 * data/location.cc: Likewise.
8050 * data/yacc.cc: Likewise.
8051 * doc/bison.texinfo (Conditions): Document this.

8056 * data/glr.cc: Remove dead code.
8058 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8060 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
8061 that variable and the line breaks the bootstrap. Problem reported
8062 by Juan M. Guerrero.
8064 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
8066 * doc/bison.texinfo (Multiple start-symbols): New.

8070 * etc/README, etc/bench.pl: New.
8072 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
8074 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
8076 Reported by Mickael Labau.
8077 * tests/input.at (Torturing the Scanner): Test it.
8079 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
8081 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
8082 Problem reported by Bob Rossi.
8084 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
8086 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
8087 and didn't really work.
8088 For the index, use @ifnotinfo, not @iftex.
8089 Minor cleanups of spacing and terminology.
8091 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
8093 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
8094 of AT_NAME_PREFIX when %name-prefix is not used.
8096 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
8098 Apply --prefix to C++ skeletons too: they change the namespace.
8099 The test suite already exercize these cases.
8100 * data/c++.m4 (b4_namespace): New.
8101 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
8102 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
8103 * data/yacc.c, data/glr.c: Remove a useless `[]'.
8104 * doc/bison.texinfo: Document it.
8105 (Option Cross Key): Use @multitable in all formats. It looks
8106 nicer, even in TeX outputs.

8119 * doc/bison.texinfo (FAQ): this.
8120 * doc/Makefile.am (EXTRA_DIST): Adjust.
8122 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
8124 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
8126 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
8127 * doc/bison.texinfo (Calc++ Scanner): Use it.
8129 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
8131 Fix two nits reported by twlevo, plus one more that I discovered.
8133 * src/assoc.h (assoc_to_string): Give a name to the arg, as
8134 this is the usual Bison style.
8135 * src/location.h (location_print): Likewise.
8137 * src/reader.h (token_name): Likewise.
8139 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
8141 Fix some nits reported by twlevo.
8142 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
8143 and "POSIX". Use more-modern syntax for URLs. Mention C++
8144 and ask for Java. Don't hardwire OS version numbers. Add
8146 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
8147 * src/conflicts.c (solved_conflicts_obstack): Now static.
8149 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
8151 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
8152 page. Say "you can use it" not "you may use it" as on the web page;
8153 we're describing capabilities not granting permission.
8155 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
8157 * data/glr.c (yyresolveLocations): Rename local variables to avoid
8158 shadowing warnings. Use usual patter for iterating through RHS.
8159 * tests/glr-regression.at
8160 (Uninitialized location when reporting ambiguity):
8161 Modify yylex so that it uses its argument, rather than trying
8162 to rely on ARGSUSED (which doesn't work for gcc with warnings).
8163 const char -> char const.
8165 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
8166 Don't use tabs inside commands; it messes up 'ps'.
8167 Problem reported by twlevo.
8169 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
8171 * tests/glr-regression.at (Uninitialized location when reporting
8172 ambiguity): New test case.
8173 * data/glr.c (yyresolveLocations): New function, which uses
8175 (yyresolveValue): Invoke yyresolveLocations before reporting an
8177 * doc/bison.texinfo (Default Action for Locations): Note
8178 YYLLOC_DEFAULT's usage for ambiguity locations.
8179 (GLR Semantic Actions): Cross-reference those notes.
8181 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
8183 * tests/glr-regression.at (Leaked semantic values when reporting
8184 ambiguity): Remove unnecessary union and type declarations.
8185 (Leaked lookahead after nondeterministic parse syntax error): New test
8187 * data/glr.c (yyparse): Check for zero stacks remaining before
8188 attempting to shift the lookahead so that you don't lose it.
8190 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
8192 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
8193 * tests/glr-regression.at (Leaked semantic values when reporting
8194 ambiguity): New test case.
8195 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
8196 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
8197 now unnecessary yystackp parameter.
8198 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
8199 destructors can be called.
8201 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
8202 in existing testcases.
8204 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
8206 Don't leak semantic values for parent RHS when a user action cuts the
8207 parser, and clean up related code a bit.
8208 * tests/glr-regression.at (Leaked merged semantic value if user action
8209 cuts parse): Rename to...
8210 (Leaked semantic values if user action cuts parse): ... this. Add check
8211 for leaked parent RHS values.
8212 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
8213 between an unresolved state (non-empty chain of semantic options) and
8214 an incomplete one (signaled by an empty chain).
8215 (yyresolveStates): Document the interface. Move all manipulation of a
8216 successfully or unsuccessfully resolved yyGLRState to...
8217 (yyresolveValue): ... here so that yyresolveValue always leaves a
8218 yyGLRState with consistent data and thus is easier to understand.
8219 Remove the yyvalp and yylocp parameters since they are always just
8220 taken from the yys parameter. When reporting a discarded merged value
8221 in debugging output, note that it is incompletely merged. Document the
8223 (yyresolveAction): If resolving any of the RHS states fails, destroy
8224 them all rather than leaking them. Thus, as long as user actions are
8225 written to clean up the RHS correctly, yyresolveAction always cleans up
8226 the RHS of a semantic option. Document the interface.
8228 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
8230 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
8231 led to a segmentation fault in GNU Pascal. Problem reported
8234 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
8236 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
8237 mid-rule action inside a nonterminal symbol in order to declare a
8238 destructor for its semantic value.
8240 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
8242 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !

8244 __cplusplus && ! defined _STDLIB_H && !
8245 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
8246 defined free))]: Include <stdlib.h> rather than rolling our own
8247 declarations of malloc and free, to avoid problems with
8248 incompatible declarations (using 'throw') C++'s stdlib.h. This
8249 should fix Debian bug 340012
8250 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
8251 reported by Guillaume Melquiond.

8255 * NEWS: Clarify symbols versus types in unused-value warnings.
8257 * configure.ac (AC_INIT): Bump version number.
8259 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
8261 * NEWS: Version 2.1a.
8262 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
8263 since C99 requires this.
8265 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
8267 * m4/c-working.m4: New file.
8268 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
8270 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
8272 * Makefile.maint: Merge from coreutils.
8274 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
8276 More portability fixes for problems summarized by Nelson H. F. Beebe.
8278 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
8279 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
8280 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
8281 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
8282 messes up because C++ code is compiled in 32-bit mode but linked

8287 More portability fixes for problems summarized by Nelson H. F. Beebe.
8289 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
8290 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
8292 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
8293 nodist_PROGRAMS, since we don't need to actually compile the
8294 example if we're just doing a plain 'make'. This avoids bothering
8295 the installer unnecessarily about problems due to weird C++
8298 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
8300 More portability fixes for problems summarized by Nelson H. F. Beebe.
8302 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
8303 than #include "...", and compile with -I'.'. The old method was
8304 not portable, according to Posix and the C standard, and it does
8305 not work with Sun C 5.7, where previous #line directives affect
8306 the working directory used in later #include "..." directives.

8314 More portability fixes for problems summarized by Nelson H. F. Beebe.
8316 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
8317 '#include <map>' works and that you can apply ++ to iterators.
8319 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
8321 Work around portability problems summarized by Nelson H. F. Beebe in
8322 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
8324 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
8325 that '#include <string>' works.
8327 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
8328 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
8329 "warning: sorry: semantics of inline function static data `const
8330 unsigned char translate_table[262]' are wrong (you'll wind up with
8333 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
8334 or, xor to not_, and_, or_, and xor_, respectively. This works
8335 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
8336 random system header somewhere that includes the equivalent of
8339 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
8340 -E" works; it apparently doesn't work with PathScale EKO Compiler
8343 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
8345 During deterministic GLR operation, user actions should be able to
8346 influence the parse by changing yychar. To make this easier to fix and
8347 to make glr.c easier to evolve in general, don't maintain yytoken in
8348 parallel with yychar; just compute yytoken when needed.
8349 * tests/glr-regression.at (Incorrect lookahead during deterministic
8350 GLR): Check that setting yychar in a user action has the intended
8352 * data/glr.c (yyGLRStack): Remove yytokenp member.
8353 (yyclearin): Don't set *yytokenp.
8354 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
8355 yychar rather than *yytokenp to determine the current lookahead.
8356 Compute yytoken locally when needed.
8357 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
8360 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
8361 after `--report' documentation.
8363 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
8365 * src/parse-gram.y (grammar_declaration): Location of printer
8366 symbol is @1, not list->location. Bug reported by twlevo.
8367 * tests/input.at (Incompatible Aliases): Adjust to above change.
8369 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
8371 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
8372 all the test at once. This makes the output easier to read in the
8375 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
8376 got from <http://bro-ids.org/download.html>. The bug is that
8377 when two actions appeared in succession, the second one was
8378 scanned before the first one was added to the grammar rule
8379 as a midrule action. Bison then output the incorrect warning
8380 "parse.y:905.17-906.36: warning: unused value: $3".
8381 * src/parse-gram.y (BRACED_CODE, action): These are no longer
8382 associated with a value.
8383 (rhs): Don't invoke grammar_current_rule_action_append.
8384 (action): Invoke it here instead.
8385 * src/reader.c (grammar_midrule_action): Now extern.
8386 (grammar_current_rule_action_append): Don't invoke
8387 grammar_midrule_action; that is now the scanner's job.
8388 * src/reader.h (last_string, last_braced_code_loc):
8389 (grammar_midrule_action): New decls.
8390 * src/scan-gram.l (last_string): Now extern, sigh.
8391 (last_braced_code_loc): New extern variable.
8392 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
8393 rule already has an action.
8394 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
8395 * tests/input.at (AT_CHECK_UNUSED_VALUES):
8396 Add some tests to check that the above changes fixed the bug.
8398 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
8400 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
8401 All used changed. Check whether the symbol has a destructor,
8402 not whether it is typed.
8403 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
8404 that the values are still reported as unused. All line numbers

8418 Work around a bug in Pike 7.0, and give the Pike folks a
8419 better way to override the usual int widths.
8420 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
8421 user can override the types.
8422 (short): #undef, to work around a bug in Pike 7.0.
8423 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
8424 (union yyalloc.yyss): Use yytype_int16 rather than short.
8426 (yysigned_char): Remove.
8427 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
8428 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.

8445 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
8448 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
8450 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
8451 since we don't want to insist on a version number at the start
8452 of the changelog every time.
8453 * Makefile.maint: Sync from coreutils a bit better.
8454 (sc_trailing_blank): Renamed from sc_trailing_space.

8553 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
8554 for the benefit of some pre-C99 compilers.

8639 (Actions): Mention look-ahead usage of yylval.
8640 (Actions and Locations): Mention look-ahead usage of yylloc.
8641 (Special Features for Use in Actions): Add YYEOF entry and mention it
8642 in the yychar entry.
8643 In the yychar entry, remove mention of the local yychar case (pure
8644 parser) since this is irrelevant information when writing semantic
8645 actions and since it's already discussed in `Table of Symbols' where
8646 yychar is otherwise described as an external variable.
8647 In the yychar entry, don't call it the `current' look-ahead since it
8648 isn't when semantic actions are deferred.
8649 In the yychar and yyclearin entries, add note about deferred semantic
8651 Add yylloc and yylval entries discussing look-ahead usage.
8652 (Look-Ahead Tokens): When discussing yychar, don't call it the

8664 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
8666 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
8667 use during nondeterministic operation to track which stacks have
8668 actually needed the current lookahead.
8669 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
8670 Allocate, deallocate, resize, and otherwise shuffle space for
8671 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.

8673 appropriately during nondeterministic operation.
8674 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
8675 members to store the current lookahead to be used by the deferred
8677 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
8678 from which the RHS is taken. Set the lookahead members of the new
8679 yySemanticOption according to the lookahead status for stack yyk.

8690 suppress lint warnings, use arguments in merge function, and assign
8691 char value < 128 in main.
8692 (Incorrect lookahead during deterministic GLR): New test case.
8693 (Incorrect lookahead during nondeterministic GLR): New test case.
8695 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

8704 * tests/glr-regression.at: For consistency with my newer test cases,
8707 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
8709 * data/glr.c (yyresolveValue): When merging semantic options, if at
8710 least one user action succeeds but a later one cuts the parse, then
8711 destroy the semantic value before returning rather than leaking it.
8712 (yyresolveStates): If a user action cuts the parse and thus
8713 yyresolveValue fails, ignore the (unset) semantic value rather than
8714 corrupting the yyGLRState, and empty the semantic options list since
8715 the user actions should have called all necessary destructors.
8716 Simplify code with YYCHK.
8717 * tests/glr-regression.at (Corrupted semantic options if user action
8718 cuts parse): New test case.
8719 (Undesirable destructors if user action cuts parse): New test case.
8720 Before applying any of this patch, this test case never actually failed
8721 for me... but only because the corrupted semantic options usually

8984 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
8985 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.

8987 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

9016 * tests/sets.at (Accept): Fix typos in regular expression used to
9017 sed out the final state number.
9019 Work around portability problem on Solaris 10: flex-generated
9020 files include <stdio.h> before <config.h>, which messes up
9021 because the latter defines __EXTENSIONS__. Address the problem
9022 by creating two new little files that include <config.h> first,
9023 then include the flex-generated files. Rewrite everyone else
9024 to include <config.h> first, as well.
9025 * lib/timevar.c: Always include "config.h".

9364 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
9366 Undo the parts of the unlocked-I/O change that substituted
9367 putc or puts for printf. This might hurt performance a bit,
9368 but some people prefer the printf style.

9399 Use unlocked I/O for a minor performance improvement on hosts like
9400 GNU/Linux and Solaris that support unlocked I/O. The basic idea
9401 is to use the gnlib unlocked-io module, and to prefer putc and

9519 indirection to YYSTYPE.

9542 (YYERROR_VERBOSE_IF): Remove.
9543 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
9544 parser members, replaced by...
9545 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
9547 (yysyntax_error_): Takes the state number as argument.
9548 (yyreduce_print_): Use the argument yyrule, not the former
9551 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
9553 * bootstrap (gnulib_modules): Add verify.
9554 * lib/.cvsignore: Add verify.h.

9560 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
9562 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
9563 local variables whose names begin with 'yy'.
9564 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
9565 Trivial changes from Joel E. Denny.
9567 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
9569 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
9570 don't use alloca any more.
9572 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
9573 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
9574 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
9575 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
9576 to match yacc.c, to test more hosts.
9578 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
9580 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
9581 doesn't affect behavior.
9582 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
9584 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
9585 This works a bit better with glibc, if user code has already included
9587 * doc/bison.texinfo (Bison Parser): Document that users can't
9588 arbitrarily use malloc and free for other purposes. Document
9589 that <alloca.h> and <malloc.h> might be included.
9590 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
9591 user must declare alloca.

9596 2005-09-20 Akim Demaille <akim@epita.fr>
9598 * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
9600 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
9602 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
9603 (YYSTACK_ALLOC_MAXIMUM): Use it.
9604 (yysyntax_error): New function.
9605 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
9606 multiple syntax errors are reported, and alloca is being used.
9607 Instead, reallocate buffers twice as big each time, so that
9608 we waste at most half the allocated memory. Start with a small
9609 (128-byte) buffer that will suffice in most cases anyway.
9610 Use yysyntax_error to do most of the work.
9612 * doc/bison.texinfo (Error Reporting, Table of Symbols):
9613 yynerrs is the number of errors reported, not the number of
9616 * tests/glr-regression.at (Duplicated user destructor for lookahead):
9617 Mark it as expected to fail.
9618 Cast result of malloc; problem reported by twlevo@xs4all.nl.
9619 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
9620 Don't start user-code symbols with "yy", to avoid name space problems.
9622 2005-09-19 Akim Demaille <akim@epita.fr>
9624 Remove the traits, failed experiment.
9625 It never proved useful, and anyway because of the current
9626 definition, it was not possible to have several specialization of
9627 this traits, making it useless.
9628 * data/lalr1.cc (yy:traits): Remove.
9629 Inline its definitions in the parser class.
9631 2005-09-19 Akim Demaille <akim@epita.fr>

9638 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
9639 and yytoken for similarity with the other skeletons.

9654 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
9655 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
9656 is not defined. This is an awful hack, but it's enough for now.
9657 All callers changed.
9658 * tests/glr-regression-at (make_value): Args are const pointers now,
9659 to avoid GCC warning.
9660 (Duplicated user destructor for lookahead): New test. Currently
9661 skipped. It fails on my host but I'm not sure it'll always fail.
9663 2005-09-16 Akim Demaille <akim@epita.fr>
9665 * src/symtab.h (struct symbol): Declare the printer and destructor
9666 as const, to avoid accidental calls to free.
9667 (symbol_destructor_set, symbol_printer_set): Adjust.
9668 * src/symtab.c: Adjust.
9670 2005-09-16 Akim Demaille <akim@epita.fr>
9672 * data/c.m4 (b4_token_enums): New.
9673 (b4_token_defines): Rename as...
9674 (b4_token_enums_defines): this.
9675 (b4_token_defines): New, output only the #defines.
9676 * data/yacc.c, data/glr.c: Adjust.
9677 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
9678 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
9681 2005-09-16 Akim Demaille <akim@epita.fr>
9683 * data/lalr1.cc (yylex_): Remove, inline its code.
9684 (yyreport_syntax_error_): Remove, replaced by...
9685 (yysyntax_error_): this which returns a string and leaves to the
9686 caller the call to the users' error function.
9687 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
9688 Move from members of the parser object...
9689 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
9690 to local variables of the parse function.
9692 2005-09-16 Akim Demaille <akim@epita.fr>
9694 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
9695 since it's in Bison's name space.
9697 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
9699 * data/glr.c (yyresolveValue): Add default case to pacify
9700 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
9702 * NEWS: Document when yyparse started to return 2.
9703 * doc/bison.texinfo (Parser Function): Document when yyparse
9706 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
9707 (b4_filename_type): Renamed back from b4_file_name_type. All uses
9709 (class position): file_name -> filename (reverting). All uses changed.
9711 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
9713 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
9714 do anything if $@ exists. This reverts part of the 2005-07-07
9717 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
9719 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
9720 contains obsolete information and isn't worth distributing as a
9721 separate file anyway.
9722 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
9723 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
9724 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
9725 (yyparse): Abort if user code uses longjmp to throw an unexpected
9728 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
9730 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
9731 Suggested by twlevo@xs4all.nl.
9733 * data/glr.c (YYCHK1): Do not assume YYE is in range.
9734 This avoids a diagnostic from gcc -Wswitch-enum.
9735 Problem reported by twlevo@xs4all.nl.
9737 * doc/bison.texinfo: Don't use "filename", as per GNU coding
9738 standards. Use "file name" or "file" or "name", depending on
9740 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
9741 not to hack/foo.tab.c.
9742 (Calc++ Top Level): 2nd arg of main is not const.
9743 * data/glr.c: b4_filename -> b4_file_name.
9744 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

9768 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
9769 All uses changed. Invoke user destructor after an error during a
9770 split parse (trivial change from Joel E. Denny).
9772 * tests/glr-regression.at
9773 (User destructor after an error during a split parse): New test case.
9774 Problem reported by Joel E. Denny in:
9775 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
9777 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9779 * README-cvs: Give URLs for recommended tools.
9780 Mention Gzip version problem, and bootstrapping issues.
9781 Remove troubleshooting section, as it's somewhat obsolete.
9783 * bootstrap (no_cache): New var, to accommodate different wget
9784 variants. Use it instead of '-C off'. Problem reported by
9787 * data/glr.c (yydestroyStackItem): New function.
9788 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
9789 debugging information. Problem reported by Joel E. Denny.

9801 Problem reported by Joel E. Denny in:
9802 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
9804 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
9806 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
9808 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
9809 lib-prefix.m4, po.m4.
9811 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
9812 in yydestruct diagnostic, since it might not be an error.
9813 Problem reported by Joel Denny near end of
9814 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9815 * data/lalr1.cc (yyerturn): Likewise.
9816 * data/yacc.c (yyreturn): Likewise.
9817 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
9819 * src/files.c: Remove obsolete FIXME comment.
9821 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
9822 with the other templates, and to fix bogus run-on messages such
9823 as the one reported at the end of
9824 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9825 All callers changed to avoid the newline.
9826 (yyprocessOneStack): Output two lines rather than one, to accommodate
9827 the above change. This changes the debug output format slightly.
9829 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
9830 reported by Joel E. Denny in
9831 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>

9838 * configure.ac (AC_INIT): Bump to 2.0c.
9840 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
9842 * NEWS: Version 2.0b.
9844 * Makefile.am (SUBDIRS): Put examples before tests, so that
9845 "make check" doesn't finish with "All 1 tests passed".
9847 * tests/regression.at (Token definitions): Don't rely on
9848 AT_PARSER_CHECK for data that contains backslashes. It currently
9849 uses 'echo', and 'echo' isn't portable if its argument contains
9850 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9851 that the byte '\0xff' is not printable in the C locale; it is,
9852 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9853 not printable, so use '\0x81' to test.
9855 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
9856 version of GCC, since the macro is used with non-GCC compilers.
9858 Fix core dump reported by Pablo De Napoli in
9859 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
9860 * tests/regression.at (Invalid inputs with {}): New test.
9861 * src/parse-gram.y (token_name): Translate type before using
9864 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
9865 the user's name space. All uses changed to __attribute__
9867 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
9868 Add __attribute__ ((__noreturn__)).
9870 * etc/clcommit: Remove. We weren't using it, and it failed
9871 "make maintainer-distcheck".
9872 * Makefile.maint: Merge from coreutils.
9873 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
9874 (syntax-check-rules): Change list of rules as described below.
9875 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

9885 Use grep -n, to make it easier to find violations.
9886 Use CVS_LIST and CVS_LIST_EXCEPT.
9887 (header_regexp, h_re): Remove.
9889 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
9890 (my-distcheck): Use more-modern GCC flags.
9891 (signatures, %.asc): Remove.
9892 (rel-files, announcement): Remove signatures.
9893 Restore old updating code, even though we don't use it, so
9894 that we're the same as coreutils.
9895 (alpha, beta, major): Depend on news-date-check.
9896 Make the upload commands.
9898 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
9899 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.

9907 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9908 we comment out the Autoconf version number.
9909 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9910 it's error-prone and "make maintainer-distcheck" rejects it.
9912 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9913 Indent calls to "error" to pacify "make maintainer-distcheck",
9914 when the calls are not intended to be translated.
9915 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9917 * src/Makefile.am (DEFS): Use +=, to pacify
9918 "make maintainer-distcheck".
9919 (bison_SOURCES): Add scan-skel.h.
9920 (sc_tight_scope): New rule, from coreutils.
9922 * src/files.c (src_extension, header_extension):
9923 Now static, not extern.
9924 * src/getargs.c (short_options): Likewise.
9925 * src/muscle_tab.c (muscle_table): Likewise.
9926 * src/parse-gram.y (current_class, current_type, current_prec):
9928 * src/reader.c (grammar_end, previous_rule_end): Likewise.
9929 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9930 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9931 void, to avoid warning when NLS is disabled.
9932 * src/output.c: Include scan-skel.h.
9933 (scan_skel): Remove decl, since scan-skel.h does this.
9935 Indent calls to "error" to pacify "make maintainer-distcheck".
9936 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9937 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9938 "make maintainer-distcheck".
9939 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
9940 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
9941 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
9942 (skel_lex_destroy, scan_skel): Move these decls to...
9943 * src/scan-skel.h: New file.
9944 * src/uniqstr.c (uniqstr_assert):
9945 Indent calls to "error" to pacify "make maintainer-distcheck".
9947 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9950 * tests/torture.at: Revamp to avoid misuse of atoi that
9951 "make maintainer-distcheck" complained about.
9953 * examples/extexi (message): Don't print a message more than once,
9954 and omit line-number decoration that makes Emacs compile think
9955 that informative messages are worth worrying about.
9957 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9959 * configure.ac: Update version number.
9961 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9963 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9964 autogenerated by the maintainer.
9965 * examples/calc++/.cvsignore: Add *.yy.
9967 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9968 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9969 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9971 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9973 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9974 from maintainer-distcheck about casting the argument of 'free'.
9976 * NEWS: Mention recent yytname changes.
9977 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9979 * bootstrap: For translations that have not yet been upgraded to
9980 the new runtime-po domain, prime the pump by extracting the
9981 relevant strings from the obsolete translations. This code can be
9982 removed once the bison-runtime domain has been translated by each
9985 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9986 now that token names are already quoted.
9988 Fix problem reported by Anthony Heading.
9989 * data/glr.c (YYTOKEN_TABLE): New macro.
9990 (yytname): Define if YYTOKEN_TABLE.
9991 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.

9996 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9998 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9999 again if the first call fails.
10001 * data/glr.c (yytnamerr): New function.
10002 (yyreportSyntaxError): Use it to dequote most string literals.
10003 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
10004 with other skeletons. All uses changed.
10005 (yytnameerr_): New function.
10006 (yyreport_syntax_error): Use it to dequote most string literals.
10007 * data/yacc.c (yytnamerr): New function.
10008 (yyerrlab): Use it to decode most string literals.
10009 * doc/bison.texinfo (Decl Summary, Calling Convention):
10010 Clarify quoting convention of yytname.
10011 * src/output.c (prepare_symbols): Quote all names. This undoes
10012 the 2005-04-17 change, which is now accomplished (mostly) via
10013 changes in the parsers as described above.
10014 * tests/regression.at (Token definitions, Web2c Actions):
10015 Undo most 2005-04-17 change here, too.
10017 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
10019 Fix more problems reported by twlevo@xs4all.nl.
10020 * tests/cxx-type.at: Don't pipe output of ./types through sed to
10021 remove trailing spaces. This loses the exit status of ./types,
10022 and isn't needed since ./types shouldn't be emitting trailing
10024 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
10025 as the stack isn't valid in that case.
10027 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
10028 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
10029 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
10030 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
10032 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
10033 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
10034 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
10037 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
10038 overly-picky compilers that reject 'char *foo = "bar";'.
10040 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
10041 to FILE * parameter, not to stderr. This fixes a typo introduced
10042 in the 2005-07-12 change.
10044 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
10045 warnings from GCC 4.
10047 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
10048 (yyglrShiftDefer, yysplitStack):
10049 Remove unused parameters b4_pure_formals. All uses changed.
10050 (yyglrShift): Remove unused parameters b4_user_formals.
10052 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
10054 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
10056 Destructor cleanups and regularization among the three skeletons.
10057 * NEWS: Document the behavior changes.
10058 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
10059 stack before failing, as the cleanup code will do it for us now.
10060 * data/lalr1.cc (yyerrlab): Likewise.
10061 * data/glr.c (yyparse): Pop everything off the stack before
10062 freeing it, so that destructors get called properly.
10063 * data/lalr1.cc (yyreturn): Likewise.
10064 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
10065 This is more consistent.
10066 * doc/bison.texinfo (Destructor Decl): Mention more reasons
10067 why destructors might be called. 1.875 -> 2.1.
10068 (Destructor Decl, Decl Summary, Table of Symbols):
10069 Some English-language cleanups for %destructor.
10070 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10071 Add output line for destructor of start symbol.
10072 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
10073 because of that same extra output line.
10075 * NEWS: Document minor wording changes in diagnostics of
10076 Bison-generated parsers.
10077 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
10078 Remove unused formals. All uses changed.
10079 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
10080 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
10081 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
10082 Rename yyoverflowab to yyexhaustedlab.
10083 When memory exhaustion occurs during syntax-error reporting,
10084 report it separately rather than in a single diagnostic; this
10086 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
10087 (Memory Exhausted): Renamed from Parser Stack Overflow.
10088 Revamp wording slightly to prefer "memory exhaustion".
10089 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
10091 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
10093 Add i18n support to the GLR skeleton. Partially fix the C++
10094 skeleton; a C++ expert needs to finish this. Remove debugging
10095 msgids; there's little point to having them translated, since they
10096 can be understood only by someone who can read the
10097 (English-language) source code.
10099 Generate runtime-po/bison-runtime.pot automatically, so that we
10100 don't have to worry about garbage getting in that file. We'll
10101 make sure after the next official release that old msgids don't
10103 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
10105 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10106 Now auto-generated.
10107 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10108 Fix typos in explanations of the runtime file.
10109 * bootstrap: Change gettext keyword from YYI18N to YY_.
10110 Use standard Makefile.in.in in runtime-po, since we'll arrange
10111 for backward-compatible bison-runtime.po files in a different way.
10112 * data/glr.c (YY_): New macro, from yacc.c.
10113 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10114 Translate messages intended for users.
10115 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10116 the wording in the other skeletons. We don't know that the memory
10118 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10119 Use same method that yacc.c uses.
10120 Don't translate debugging messages.
10121 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10122 it doesn't work (yet), and requires C++ expertise to fix.
10123 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10124 Move defn to a more logical place, to be consistent with other
10126 Don't translate debugging messages.
10127 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10128 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10129 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10130 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
10132 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
10133 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
10135 * tests/glr-regression.at (Badly Collapsed GLR States):
10137 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
10138 yylex should return 0 at EOF rather than aborting.
10140 Improve tests for stack overflow in GLR parser.
10141 Problem reported by twlevo@xs4all.nl.
10142 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
10144 (yyStackOverflow): Just longjmp, but with value 2 so that caller
10145 can handle the problem.
10146 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
10147 (yyparse): New local variable yyresult to record the result.
10148 Use result of setjmp to set it, rather than storing itinto
10150 (yyDone): Remove label.
10151 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
10152 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
10153 if YYABORT is used).
10154 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
10155 yyparse status; put status > 1 into diagnostic.
10156 Check that status==2 works.
10157 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
10158 Use exit status 3 for failure to open (which shouldn't happen).
10160 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
10162 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
10163 1 on syntax error; just let yyparse do its thing.
10164 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
10165 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
10166 (Exploding the Stack Size with Alloca):
10167 (Exploding the Stack Size with Malloc):
10168 Expect exit status 2, not 1, since the parser is supposed to blow
10169 its stack. Problem reported by twlevo@xs4all.nl.
10171 * data/glr.c (yyparse): Don't assume that the initial calls
10172 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
10173 Print a stack-overflow message and fail instead.
10174 Initialize the line-number information before creating the stack,
10175 so that the stack-overflow message can report line zero safely.
10177 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
10179 Fix problems reported by twlevo@xs4all.nl.
10180 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
10181 (yyuserMerge): Provide a default case if b4_mergers is empty.
10182 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
10183 * tests/glr-regression.at
10184 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
10185 Add casts to pacify C++ compilers.
10186 * tests/glr-regression.at (Improper merging of GLR delayed action
10187 sets): Declare yylex before using it.
10188 * tests/Makefile.am (maintainer-check-g++): Fix a stray
10189 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
10190 test for valgrind; valgrind is independent of g++.
10191 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
10192 for compatibility with POSIX 1003.1-2001 (if running coreutils).
10193 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
10194 Use a destructor, so that we can expand the stack. Change
10195 YYSTYPE to char * so that we can free it. Cast result of malloc.
10197 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10199 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
10200 a valgrind failure. Problem reported by twlevo@xs4all.nl.
10202 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
10204 * PACKAGING: New file, suggested by Bruno Haible and taken from
10205 similar wording in gettext's PACKAGING file.
10206 * NEWS: Mention PACKAGING.
10207 * Makefile.am (EXTRA_DIST): Add PACKAGING.
10209 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
10211 * NEWS: Document recent i18n improvements.
10212 * bootstrap: Get runtime translations into runtime-po.
10213 Create runtime-po files automatically, if possible.
10214 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
10215 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
10216 does not infringe on the user's name space.
10217 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
10218 * doc/bison.texinfo (Internationalization): Revamp the English
10219 and Texinfo syntax a bit, to try to make it clearer.
10220 (Bison Options, Option Cross Key): Mention --print-localedir.
10221 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
10222 YYENABLE_NLS. Quote a bit more.
10223 * runtime-po/.cvsignore: New file.
10224 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
10225 * runtime-po/Rules-quot: Remove; now created by bootstrap.
10226 * runtime-po/quot.sed: Likewise.
10227 * runtime-po/boldquot.sed: Likewise.
10228 * runtime-po/en@quot.header: Likewise.
10229 * runtime-po/en@boldquot.header: Likewise.
10230 * runtime-po/insert-header.sin: Likewise.
10231 * runtime-po/remove-potcdate.sin: Likewise.
10232 * runtime-po/Makevars: Likewise.
10233 * runtime-po/LINGUAS: Likewise.
10234 * runtime-po/de.po: Likewise; we will rely on the translation project
10235 to maintain this, so "bootstrap" should get it.
10236 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
10238 * src/main.c (main): Bind the bison-runtime domain, too.
10240 2005-07-12 Bruno Haible <bruno@clisp.org>
10242 * data/yacc.c: Include <libintl.h> when NLS is enabled.
10243 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
10244 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
10245 * runtime-po: New directory.
10246 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
10247 $(DOMAIN).pot-update rule, so that old messages are never dropped.
10248 * runtime-po/Rules-quot: New file, copied from po/.
10249 * runtime-po/quot.sed: Likewise.
10250 * runtime-po/boldquot.sed: Likewise.
10251 * runtime-po/en@quot.header: Likewise.
10252 * runtime-po/en@boldquot.header: Likewise.
10253 * runtime-po/insert-header.sin: Likewise.
10254 * runtime-po/remove-potcdate.sin: Likewise.
10255 * runtime-po/Makevars: New file.
10256 * runtime-po/POTFILES.in: New file.
10257 * runtime-po/LINGUAS: New file.
10258 * runtime-po/bison-runtime.pot: New file.
10259 * runtime-po/de.po: New file.
10260 * m4/bison.m4: New file.
10261 * Makefile.am (SUBDIRS): Add runtime-po.
10262 (aclocaldir, aclocal_DATA): New variables.
10263 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
10265 * src/getargs.c (usage): Document --print-localedir option.
10266 (PRINT_LOCALEDIR_OPTION): New enum item.
10267 (long_options): Add --print-localedir option.
10268 (getargs): Handle --print-localedir option.
10269 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
10270 (Internationalization): New section.
10272 2005-07-12 Akim Demaille <akim@epita.fr>
10274 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
10275 for consistency with the rest of the code.
10276 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
10279 2005-07-12 Akim Demaille <akim@epita.fr>
10281 * src/parse-gram.y: Use %printer instead of YYPRINT.
10283 2005-07-12 Akim Demaille <akim@epita.fr>
10285 * src/symtab.h, src/symtab.c (symbol_print): New.
10286 * src/symlist.h, src/symlist.c (symbol_list_print): New.
10287 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
10289 2005-07-12 Akim Demaille <akim@epita.fr>
10291 * data/glr.c (b4_syncline): Fix (swap) the definitions of
10292 b4_at_dollar and b4_dollar_dollar.
10294 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
10296 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
10297 and Pennello's paper.
10299 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
10301 * data/yacc.c (yyparse): Undo previous patch. Instead,
10302 set yylsp[0] and yyvsp[0] only if the initial action
10303 sets yylloc and yylval, respectively.
10305 * data/yacc.c (yyparse): In the initial action, set
10306 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
10307 This avoids the use of undefined variables if the initial
10308 action does not set yylloc and/or yylval.
10310 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10312 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
10313 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
10314 Remove from CVS. These files are automatically generated.
10315 * examples/extexi: Clarify that this file is now part of Bison,
10316 not GNU M4, and that it works with any POSIX-compatible Awk.
10317 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
10318 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
10319 so that we also get calc++-parser.yy. Geneate it.
10320 Use $(AWK), not gawk, since any conforming Awk will do.
10321 Put comment before action, since older 'make' can't handle comment
10323 $(BUILT_SOURCES): List all built sources, not just some of them.
10324 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
10325 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
10326 $($(calc_sources_generated)): Remove unnecessary test for existence
10327 of target. (This had a shell syntax error anyway; a stray "x".)
10328 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
10330 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
10332 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
10333 implied by the other modules.
10335 2005-07-06 Akim Demaille <akim@epita.fr>
10337 Bind examples/calc++ to the package.
10338 * examples/calc++/Makefile: Remove, replaced by...
10339 * examples/calc++/Makefile.am: ... this new file.
10340 * examples/calc++/test: Remove input.
10341 * examples/calc++/compile: Remove.
10342 * examples/Makefile.am: New.
10343 * configure.ac, Makefile.am: Adjust.
10344 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
10346 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
10348 * data/glr.c (yyFail): Drastically simplify; since the format argument
10349 never had any % directives, we can simply pass it to yyerror.
10350 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
10351 be modified later, as that is the usual style in glr.c.
10352 Problems reported by Paul Hilfinger.
10354 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
10355 and size overflow errors.
10356 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
10357 in case the user prolog sets feature-test macros like _GNU_SOURCE.
10358 (YYSIZEMAX): New macro.
10359 (yystpcpy): New function, taken from yacc.c.
10360 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
10361 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
10362 so that we don't have to maintain their signatures.
10363 (yyFail): Check for buffer overflow, by using vsnprintf rather
10364 than vsprintf. Allocate a bigger buffer if possible.
10365 Report an error if buffer allocation fails.
10366 (yyStackOverflow): New function.
10367 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
10368 the initialization was successful. It might fail if storage was
10370 (yyexpandGLRStack): Add more checks for storage allocation failure.
10371 Use yyStackOverflow to report failures.
10372 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
10373 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
10374 Don't assume stack number fits in int.
10375 (yysplitStack): Check for storage allocation failure.
10376 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
10377 can print diagnostics on storage allocation failure. All callers
10379 (yyresolveValue): Use yybool for boolean.
10380 (yyreportSyntaxError): Check for size-calculation overflow.
10381 This code is taken from yacc.c.
10382 (yyparse): Check for storage allocation errors when allocating
10385 2005-07-05 Akim Demaille <akim@epita.fr>
10387 Extract calc++ from the documentation.
10388 * doc/bison.texinfo (Calc++): Add the extraction marks.
10389 * examples/extexi: New, from the aborted GNU Programming 2E.
10390 Separate the different paragraph of a file with empty lines.
10391 * examples/Makefile: Use it to extract the whole calc++ example.
10393 2005-06-24 Akim Demaille <akim@epita.fr>
10395 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
10398 2005-06-22 Akim Demaille <akim@epita.fr>
10400 * doc/bison.texinfo (C++ Language Interface): First stab.
10401 (C++ Parsers): Remove.
10403 2005-06-22 Akim Demaille <akim@epita.fr>
10405 * data/lalr1.cc (yylex_): Honor %lex-param.
10407 2005-06-22 Akim Demaille <akim@epita.fr>
10409 Start a set of simple examples.
10410 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
10411 * examples/calc++/calc++-driver.hh,
10412 * examples/calc++/calc++-parser.yy,
10413 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
10414 * examples/calc++/compile, examples/calc++/test: New.
10416 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
10418 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
10419 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
10420 which stems from the 2005-05-27 patch.
10422 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
10424 * data/glr.c: Modify treatment of unused parameters to permit use
10425 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
10427 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
10429 Fix infringement on user name space reported by Janos Zoltan Szabo.
10430 * data/yacc.c (yyparse): strlen -> yystrlen.
10432 2005-05-30 Akim Demaille <akim@epita.fr>
10434 * data/lalr1.cc (_): New.
10435 Translate the various messages.
10437 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
10439 Fix infringement on user name space reported by Bruno Haible.
10440 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
10441 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
10442 the user's name space.
10443 (alloca): Include <stdlib.h> to get it, if it's not built in.
10444 (YYMALLOC, YYFREE): Define only if needed.
10445 (malloc, free): Declare, but only if needed, as this infringes on
10446 the user name space.
10448 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10450 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
10451 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
10453 * lib/ebitset.c (min, max): Undef before defining.
10454 * lib/vbitset.c (min, max): Likewise.
10455 * lib/subpipe.c (create_subpipe): Save local variables in case
10456 vfork clobbers them.
10458 2005-05-24 Bruno Haible <bruno@clisp.org>
10460 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
10461 error message syntax used by gcc-4.0.
10463 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
10465 * README: Mention m4 1.4.3. Remove obsolete advice about
10466 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
10468 * bootstrap: Remove workaround for problem I encountered with
10469 gettext 0.14.1; it seems to be fixed now.
10471 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
10473 * NEWS: Version 2.0a.
10475 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
10476 the previous change.
10478 Various maintainer cleanups.
10479 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
10480 conftest*, for benefit of CVS commands run at the same time as
10481 "configure". Add build-aux, since "bootstrap" now creates it and
10483 * Makefile.cfg (move_if_change): Remove.
10484 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
10485 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
10486 (po_repo, do-po-update, po-update, wget_files, get-targets):
10487 (config.guess-url_prefix, config.sub-url_prefix):
10488 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):

10490 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
10492 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
10493 this is now the recommended name.
10494 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
10495 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
10496 ylwrap. These files now go into build-aux.
10497 * config/move-if-change: Remove.
10498 * config/prev-version.txt: Bump from 1.75 to 2.0.
10500 * bootstrap: Add stdio-safer, unistd-safer modules.
10501 Remove m4/glibc2.m4 (introduced by latest gnulib, but

10504 fopen-safer.c, stdio-safer.h, unistd-safer.h.
10505 * lib/subpipe.c: Include "unistd-safer.h".
10506 (create_subpipe): Make sure all the newly-created
10507 file descriptors are > 2, so that diagnostics don't
10508 get sent down them (which might cause Bison to hang, in theory).
10509 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
10510 * src/files.c (xfopen): Use fopen_safer, not fopen.
10512 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
10513 yesterday's yacc.c fix.
10515 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
10517 * data/glr.c, data/lalr1.cc: Update copyright date.
10519 Fix a destructor bug reported by Wolfgang Spraul in
10520 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
10521 * data/yacc.c (yyabortlab): Don't call destructor, and
10522 don't set yychar to EMPTY.
10523 (yyoverflowlab): Don't call destructor.
10524 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
10525 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
10526 since we no longer output the message "discarding lookahead token
10529 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10531 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
10532 fix a small glitch in debugging output.
10533 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
10534 after YY_SYMBOL_PRINT where needed.
10536 (struct yyGLRState): Add some comments.
10537 (struct yySemanticOption): Add some comments.
10538 (union yyGLRStackItem): Add comment.
10540 (yymergeOptionSets): Correct this to properly perform the union,
10541 avoiding infinite reported by Michael Rosien.
10544 * tests/glr-regression.at: Add test for GLR merging error reported

10585 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
10587 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
10588 Problem reported by Ralf Menzel.
10590 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10592 * tests/actions.at: Test that stack overflow invokes destructors.
10593 From Marcus Holland-Moritz.
10594 * data/yacc.c (yyerrlab): Move the code that destroys the stack
10596 (yyreturn): to here. That way, destructors are called properly
10597 even if the stack overflows, or the user calls YYACCEPT or
10598 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
10599 (yyoverflowlab): Destroy the lookahead.
10601 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
10603 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
10605 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
10607 * NEWS: Bison-generated C parsers no longer quote literal strings
10608 associated with tokens.
10609 * src/output.c (prepare_symbols): Don't escape strings,
10610 since users don't want to see C escapes.
10611 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
10613 * tests/input.at (Torturing the Scanner): Likewise.
10614 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
10616 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
10618 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
10619 the data size is known to be too small and we can't increase it.
10620 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
10622 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
10624 * src/parse-gram.y: Include quotearg.h.
10625 (string_as_id): Quote $1 before using it as a key, since the
10626 lexer no longer quotes it for us.
10627 (string_content): Don't strip quotes, since lexer no longer
10629 * src/scan-gram.l: Include quotearg.h.
10630 ("\""): Omit quote.
10631 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
10632 a key, since the rest of the lexer doesn't quote it.
10633 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
10634 * tests/regression.at (Token definitions): Check for backslashes
10637 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
10638 (YYSIZE_T): Define to unsigned long int when using an older compiler.
10639 (yyparse): Revamp code to generate long syntax error message, to
10640 make it easier to translate, and to avoid problems with arithmetic
10641 overflow. Change "virtual memory" to "memory" in diagnostic, since
10642 we don't know whether the memory is virtual.
10644 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10646 * NEWS: Bison-generated C parsers now use the _ macro to
10648 * data/yacc.c (_) [!defined _]: New macro.
10649 All English strings wrapped inside this macro.
10650 * doc/bison.texinfo (Bison Parser): Document _.
10651 * po/POTFILES.in: Include src/parse-gram.c, since it now
10652 includes translateable strings that parse-gram.y doesn't.
10654 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
10656 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
10657 reverting the 2004-10-11 change to this function.
10658 (symbol_check_alias_consistency): Don't call symbol_type_set
10659 if the type name is already correct.
10660 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
10662 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
10664 * tests/regression.at (Token definitions): Don't use a token named
10665 c, as that generates a "#define c ..." that runs afoul of buggy
10666 stdlib.h that uses the identifier c as a member of struct
10667 drand48_data. Problem reported by Horst Wente.
10669 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
10671 * bootstrap: Change translation URL from
10672 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
10673 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
10674 redirection glitches. Problem reported by twlevo@xs4all.nl.
10676 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
10678 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
10679 after operands; POSIX says this isn't portable for the c99 command.
10681 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
10683 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
10684 immediately if a data overrun has occurred; this may help us track
10685 down what may be a spurious failure on MacOS.
10687 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
10689 Respond to problems reported by twlevo@xs4all.nl.
10691 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
10693 * src/vcg.h: Comment fix.
10694 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
10695 (G_CMAX): Change to -1 instead of INT_MAX.
10697 * data/yacc.c (yyparse): Omit spaces before #line.
10699 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
10701 * src/tables.c (state_number_to_vector_number): Put it inside an
10702 "#if 0", since it's not currently used. Problem reported by
10705 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
10707 * src/output.c (escaped_output): Renamed from
10708 escaped_file_name_output, since we now use it for symbol tags as
10709 well. All uses changed.
10710 (symbol_destructors_output, symbol_printers_output):
10711 Escape symbol tags too.
10712 Problem reported by Matyas Forstner in
10713 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
10715 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
10717 * src/output.c (user_actions_output, token_definitions_output,
10718 symbol_destructors_output, symbol_printers_output): Likewise.
10719 * src/reader.c (prologue_augment): Likewise.
10720 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
10722 * src/vcg.c (output_edge): Don't quote linestyle arg.
10723 Problem reported by twlevo@xs4all.nl.
10725 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
10727 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
10728 example, reported by Derek M Jones. Also, make the example even
10729 more outrageous, to better illustrate how bad the problem is.
10731 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
10733 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
10734 putsym. Typo reported by Sebastian Piping.
10736 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10738 * doc/bison.texinfo (Language and Grammar): some -> same
10739 (Epilogue): int he -> in the
10740 Typos reported by Sebastian Piping via Justin Pence.
10742 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10744 * tests/glr-regression.at (Improper handling of embedded actions
10745 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
10746 embedded actions and $-N in GLR parsers", work around an Autoconf bug
10747 with dollar signs in test names.
10748 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
10749 for a similar reason.
10751 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
10753 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
10754 wants to redefine G_VIEW.
10756 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
10758 * src/vcg.c (get_view_str): Remove case for normal_view.
10759 Problem reported by twlevo@xs4all.nl.
10761 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
10763 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
10764 Problem reported by twlevo@xs4all.nl.
10766 * doc/bison.texinfo: Change @dircategory from "GNU programming
10767 tools" to "Software development". Requested by Richard Stallman
10770 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
10772 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
10773 Problem reported by twlevo@xs4all.nl.
10775 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
10777 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
10778 keyword; it's not needed with modern compilers, and it doesn't
10779 affect correctness with older compilers. Suggested by
10782 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
10784 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
10785 gcc -Wswitch-default.
10786 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10787 * data/yacc.c (yyparse): Likewise.
10789 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
10791 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
10792 already. Let config.h define any nonstandard values.
10794 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
10796 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
10797 for the benefit of slower hosts. Problem reported by
10798 Nelson H. F. Beebe.
10800 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
10802 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
10803 being defined and not used.
10804 * data/lalr1.cc (yyparse): Likewise.
10805 Use "if (false)" rather than "if (0)".
10807 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
10809 * TODO: Mention that we should allow NUL bytes in tokens.
10811 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
10813 * src/scan-skel.l (<<EOF>>): Don't close standard output.
10814 Problem reported by Hans Aberg.
10816 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
10818 * src/getargs.c (version): Happy new year; update overall
10819 program copyright date from 2004 to 2005.
10821 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
10822 Problem reported by Hans Aberg.
10823 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
10824 (Output file names.): Add a test for the case when standard output
10827 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
10829 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
10830 to fix an oversight in the Bison 2.0 manual.
10832 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
10834 * NEWS: Version 2.0. Reformat the existing news items since
10835 1.875, so that related items are grouped together.
10836 * configure.ac (AC_INIT): Bump version to 2.0.
10837 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
10839 * tests/torture.at (Exploding the Stack Size with Alloca): Set
10840 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
10841 otherwise, we're not testing alloca. Unfortunately there's no
10842 simple way to consult HAVE_ALLOCA here.
10844 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
10847 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
10848 hand. This avoids a warning about comparing int to size_t when
10849 GCC warnings are enabled.
10851 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
10853 * NEWS: Bison-generated parsers no longer default to using the
10854 alloca function (when available) to extend the parser stack, due
10855 to widespread problems in unchecked stack-overflow detection.
10856 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
10857 responsibility to set it to a positive value. This lets the user
10858 specify a value that is not a preprocessor constant.
10859 * data/yacc.c (YYMAXDEPTH): Likewise.
10860 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
10861 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
10862 to be a compile-time constant. However, explain the constraints on it.
10863 Also, explain the constraints on YYINITDEPTH.
10864 (Table of Symbols): Explain that alloca is no longer the default.
10865 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
10868 * doc/bison.texinfo (Location Default Action): Mention that n must
10869 be zero when k is zero. Suggested by Frank Heckenbach.
10871 2004-12-22 Akim Demaille <akim@epita.fr>
10873 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
10874 (parser::state_type, parser::semantic_type, parser::location_type):
10875 Private, not public.
10876 (parser::parse): Return ints, not bool.
10877 Returning a bool introduces a problem: 0 corresponds to false, and
10878 it seems weird to return false on success. Returning true changes
10879 the conventions for yyparse.
10880 Alternatively we could return void and send an exception.
10881 There is no clear consensus (yet?).
10882 (state_stack, semantic_stack, location_stack): Rename as...
10883 (state_stack_type, semantic_stack_type, location_stack_type): these.
10884 Private, not public.

10890 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
10892 2004-12-21 Akim Demaille <akim@epita.fr>
10894 Don't impose std::string for filenames.
10896 * data/lalr1.cc (b4_filename_type): New.
10897 (position::filename): Use it.
10898 (parser.hh): Move the inclusion of stack.hh and location.hh below
10899 the user code, so that needed headers for the filename type can be
10901 Forward declare them before the user code.
10902 * tests/Makefile.am (check-local, installcheck-local): Pass
10903 TESTSUITEFLAGS to the TESTSUITE.
10905 2004-12-20 Akim Demaille <akim@epita.fr>
10907 Use more STL like names: my_class instead of MyClass.

10910 (SemanticStack, SemanticType, StateStack, StateType)
10911 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10912 (Parser::value): Rename as...
10913 (location_stack, location_type, rhs_number_type, semantic_stack)
10914 (semantic_type, state_stack, state_type, token_number_type, stack)
10915 (slice, traits, parser::yylloc, parser::yylval): these.
10917 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10919 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10921 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10922 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10924 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10926 Remove uses of 'short int' and 'unsigned short int'. This raises
10927 some arbitrary limits. It uses more memory but nowadays that's
10928 not much of an issue.
10930 This change does not affect the generated parsers; that's a different
10931 task, as some users will want to conserve memory there.
10933 Ideally we should use size_t to represent all object counts, and
10934 something like ptrdiff_t to represent signed differences of object
10935 counts; but that will require more code-cleanup than I have the
10936 time to do right now.
10938 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10939 Use size_t, not int or short int, to count objects.
10940 * src/closure.c (nritemset, closure): Likewise.

10951 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
10952 errs, reductions): Likewise.

10955 * src/tables.c (vector_number, tally, action_number,
10956 ACTION_NUMBER_MINIMUM): Likewise.
10957 * src/output.c (muscle_insert_short_int_table): Remove.
10959 2004-12-17 Akim Demaille <akim@epita.fr>
10961 * data/lalr1.cc: Extensive Doxygenation.
10962 (error_): Rename as...
10963 (error): this, since it is visible to the user.
10965 (Parser::message): Now an automatic variable from...
10966 (Parser::yyreport_syntax_error_): here.
10967 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10969 * tests/input.at: Escape $.

10973 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10974 Parenthesize rhs to avoid obscure problems with mistakes like
10975 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10976 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10977 b4_rhs_location): Likewise.
10978 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10979 b4_rhs_location): Likewise.
10981 2004-12-16 Akim Demaille <akim@epita.fr>
10983 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10984 yacc.c: be sure to stay within yycheck_.
10985 * tests/actions.at: Re-enable C++ tests.
10987 2004-12-16 Akim Demaille <akim@epita.fr>
10989 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
10992 2004-12-16 Akim Demaille <akim@epita.fr>
10994 Use #define to handle the %name-prefix.
10996 * data/glr.c, data/yacc.c: Comment changes.
10997 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10998 so that one can refer to yylex in the parser file, and have it
10999 renamed, as is the case with other skeletons.
11001 2004-12-16 Akim Demaille <akim@epita.fr>
11003 Move lalr1.cc internals into yy*.

11023 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
11025 Fix some problems reported by twlevo at xs4all.
11026 * src/symtab.c (symbol_new): Report an error if the input grammar
11027 contains too many symbols. This is better than calling abort() later.
11028 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
11029 (struct node, struct graph):
11030 Rename member expand to stretch. All uses changed.
11031 (struct graph): Remove member layoutalgorithm. All uses removed.
11032 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
11033 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
11035 (N_STRETCH): Rename from N_EXPAND. All uses changed.
11037 2004-12-15 Akim Demaille <akim@epita.fr>
11039 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
11040 Add more Doxygen comments.
11041 (symprint_, stack_print_, reduce_print_, destruct_, pop)
11042 (report_syntax_error_, translate_): Rename as...
11043 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
11044 (yypop_, yyreport_syntax_error_, yytranslate_): this.
11046 2004-12-15 Akim Demaille <akim@epita.fr>
11048 * data/lalr1.cc (lex_): Rename as...
11050 Move the trace here.
11051 Take the %name-prefix into account.
11052 Reported by Alexandre Duret-Lutz.
11054 2004-12-15 Akim Demaille <akim@epita.fr>
11056 Simplify the C++ parser constructor.
11058 * data/lalr1.cc (debug_): Rename as...
11059 (yydebug_): so that the parser's internals are always in the yy*
11062 (b4_parse_param_decl): Remove the leading comma as it is now only
11063 called as unique argument list.
11064 (Parser::Parser): Remove the constructor accepting a location and
11065 an initial debugging level.
11066 Remove from the other ctor the argument for the debugging level.
11067 (debug_level_type, debug_level, set_debug_level): New.
11069 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
11072 2004-12-15 Akim Demaille <akim@epita.fr>
11074 Remove b4_root related material: failure experiment
11075 (which goal was to allow to derive from a class).
11077 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
11078 definitions and uses.
11080 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
11082 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
11083 not 2, since it's not portable to subtract 1 from the start of an
11084 array. The new item 0 is never set or used. All uses changed.
11086 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
11087 the default definition of YYLLOC_DEFAULT. Problem reported
11088 by Frank Heckenbach.
11090 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
11092 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
11093 the normal case and one for the error case. Just use the
11094 first one uniformly. Problem reported by Frank Heckenbach.
11095 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
11096 use exactly the same macro in both places.
11097 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
11098 so that the normal-case YYRHSLOC works for the error case too.
11100 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
11101 (YYLLOC_DEFAULT): Use the same macro as glr.c.
11102 * doc/bison.texinfo (Location Default Action): Don't claim that
11103 we have an array of locations. Use the same macro for both glr
11104 and lalr parsers. Mention YYRHSLOC. Mention what happens when
11107 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>

11116 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
11118 * src/scan-skel.l: Include "complain.h", for "fatal".
11120 * src/relation.h (relation_print, relation_digraph):
11121 Relation sizes are of type relation_node, not size_t (this is
11122 merely a doc fix, since the two types are equivalent).
11123 (relation_transpose): Relation sizes are of type relation_node,
11125 * src/relation.c: Likewise.
11126 (top, infinity): Now of type relation_node, not int.
11127 (traverse, relation_transpose): Use relation_node, not int.
11129 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
11130 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
11131 (yyparse): Remove unused local introduced in 2004-10-25 patch.
11133 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
11134 specifying whether the test should be skipped. Use it tp
11135 specify that the [%defines %skeleton "lalr1.cc"] tests currently
11136 fail on some hosts, and should be skipped.
11138 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
11140 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
11141 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
11142 unless otherwise specified below.
11144 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
11145 to allocate kernel_base, kernel_items, kernel_size, since
11146 they needn't be initialized to 0.
11147 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
11148 * src/closure.c (new_closure): Likewise, for itemset.

11165 (pack_table): Likewise for base, pos, check.
11166 (tables_generate): Likewise for width.
11168 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
11169 for initial core. Just have a separate core, so we needn't worry
11170 about whether kernel_size and kernel_base are initialized.
11172 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
11173 kernel_size, kernel_items): Remove unnecessary initialization.

11178 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
11179 conflrow, conflict_table, conflict_list, table, check):
11182 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
11183 This is because all callers pass unsigned int.
11184 * src/closure.h (new_closure): Likewise.
11186 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
11187 (build_relations): Initialize includes[i] in all cases.
11188 * src/reader.c (packgram): Always initialize rules[ruleno].prec
11189 and rules[ruleno].precsym. Initialize members in order.
11190 * src/relation.c (relation_transpose): Always initialize new_R[i]
11192 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
11194 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
11195 conflict_list[0] was always 0, but now it isn't initialized.
11197 * src/table.c (table_grow): When conflict_table grew, the grown
11198 area wasn't cleared. Fix this.
11200 * lib/.cvsignore: Add strdup.c, strdup.h.
11201 * m4/.cvsignore: Add strdup.m4.
11203 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
11205 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
11206 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
11207 GOTO_NUMBER_MAXIMUM, since we occasionally compute
11208 ngotos + 1 without checking for overflow.
11209 (build_relations): Use END_NODE, not -1, to denote end of edges.
11210 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
11211 build_relations): Use goto_number, not int, for goto numbers.
11212 * src/tables.c (save_column, default_goto): Likewise.
11214 2004-11-23 Akim Demaille <akim@epita.fr>
11216 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
11217 of #defining from yystype.
11218 Don't typedef yystype, C++ does not need it.
11219 This lets it possible to forward declare it as union.
11221 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
11223 * bootstrap (gnulib_modules): Add extensions.
11224 Problem reported by Jim Meyering.

11229 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
11230 src/system.h, src/tables.c: XFREE -> free, to accommodate
11231 recent change to gnulib xalloc.h.
11232 Problem reported by Jim Meyering.
11234 2004-11-17 Akim Demaille <akim@epita.fr>

11238 2004-11-17 Akim Demaille <akim@epita.fr>,
11239 Alexandre Duret-Lutz <adl@gnu.org>
11241 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow

11260 * data/glr.c (yyloc_default): Remove; not used.
11261 Problem reported by Frank Heckenbach.
11263 2004-10-25 Akim Demaille <akim@epita.fr>
11265 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
11266 Introduce another definition to address simple location arrays.
11267 (yyGLRStack): New member: yyerror_range.
11268 (yyrecoverSyntaxError, yyparse): Update it.
11269 (yyrecoverSyntaxError): Use it when shifting the error token to
11270 have an accurate range, equivalent to the one computed by both
11271 yacc.c and lalr1.cc.
11272 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
11273 that column numbers start at column 0, as per GNU Coding
11274 Standards, the others tests, and the doc.
11275 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
11276 Adjust to the above change (first column is 0).
11277 And adjust the location of the "<error>", now covering the whole
11280 2004-10-22 Akim Demaille <akim@epita.fr>
11281 and Paul Eggert <eggert@cs.ucla.edu>
11283 Remove some arbitrary limits on goto numbers and relations.
11284 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
11285 initial values, since they're never used.
11286 (set_goto_map): ngotos is now unsigned, so test for overflow
11287 by seeing whether it wraps around to zero.
11288 * src/lalr.h (goto_number): Now size_t, not short int.
11289 (GOTO_NUMBER_MAXIMUM): Remove.
11290 * src/relation.c (relation_print, traverse, relation_transpose):
11291 Check for END_NODE rather than looking at sign.
11292 * src/relation.h (END_NODE): New macro.
11293 (relation_node): Now size_t, not short int.
11295 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
11297 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
11298 keyword, not an identifier. Problem reported by Baron Schwartz in
11299 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
11301 2004-10-11 Akim Demaille <akim@epita.fr>
11303 * src/symtab.c (symbol_check_alias_consistency): Also check
11304 type names, destructors, and printers.
11305 Reported by Alexandre Duret-Lutz.
11306 Recode the handling of associativity and precedence in terms
11307 of symbol_precedence_set.
11308 Accept no redeclaration at all, not even equal to the previous
11310 (redeclaration): New.
11311 Use it to factor redeclaration complaints.
11312 (symbol_make_alias): Don't set the type of the alias, let
11313 symbol_check_alias_consistency do it as for other features.
11314 * src/symtab.h (symbol): Add new member prec_location, and
11316 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
11317 * tests/input.at (Incompatible Aliases): New.
11319 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
11321 .cvsignore fixes to accommodate gnulib changes,
11322 and the practice of naming build directories "_build".
11323 * .cvsignore: Add "_*". Sort.
11324 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
11325 * m4/.cvsignore: Add "*_gl.m4".
11327 2004-10-06 Akim Demaille <akim@epita.fr>
11329 * src/parse-gram.y (add_param): Fix the truncation of trailing
11332 2004-10-05 Akim Demaille <akim@epita.fr>
11334 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11335 whether the reducion was empty or not. This leaves room to
11336 improve the use of YYLLOC_DEFAULT in such a case.
11337 lalr1.cc is still experimental, so changing this is acceptable.
11338 And finally, there are probably not many users who changed the
11339 handling of locations in GLR, so changing is admissible too.
11341 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
11342 empty reduction, set @$ to an empty location ending the previously
11344 Adjust uses to make sure the code is triggered on empty
11346 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
11347 expected output: empty reductions have empty locations.
11349 2004-09-29 Akim Demaille <akim@epita.fr>
11351 * data/lalr1.cc: Move towards a more standard C++ coding style
11352 for templates: Class < T > -> Class<T>.
11354 2004-09-29 Akim Demaille <akim@epita.fr>
11356 * data/lalr1.cc: Reinstall the former ctor, for sake of
11357 compatibility, but warn it will be removed.
11358 Move towards a more standard C++ coding style (i.e., type *var ->
11361 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
11363 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
11364 since it's less likely to work if NULs are involved in the future.
11366 2004-09-27 Akim Demaille <akim@epita.fr>
11368 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
11370 2004-09-27 Akim Demaille <akim@epita.fr>
11372 * data/lalr1.cc (b4_parse_param_decl_1): New.
11373 (b4_parse_param_decl): Use it to have different names between attribute
11374 and argument names.
11375 (b4_cc_constructor_call): Likewise.
11377 2004-09-24 Akim Demaille <akim@epita.fr>
11379 * src/parse-gram.y (add_param): Strip the leading and trailing
11380 blanks from a formal argument declaration.
11381 (YY_LOCATION_PRINT): New.
11383 2004-09-24 Akim Demaille <akim@epita.fr>
11385 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
11386 after the location.
11388 2004-09-24 Akim Demaille <akim@epita.fr>
11390 * doc/bison.texinfo (Table of Symbols): Sort.
11392 2004-09-21 Akim Demaille <akim@epita.fr>
11394 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
11395 the useless parentheses.
11396 Suggested by Paul Eggert.
11398 2004-09-20 Akim Demaille <akim@epita.fr>
11400 Let the initial-action act on the look-ahead, and use it for the
11401 "initial push" (corresponding to an hypothetical beginning-of-file).
11402 And let lalr1.cc honor %initial-action.
11404 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
11406 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
11407 (Parser::Parser): Remove the ctor that used to initialize it.
11408 (Parser::parse): Like in the other skeletons, issue the "starting
11409 parse" message before any action.
11410 Honor %initial-action.
11411 Initialize the stacks with the lookahead.
11412 * data/yacc.c: Let $$ and @$ in %initial-action designate the
11414 Push them in the stacks.
11415 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
11417 2004-09-20 Akim Demaille <akim@epita.fr>
11419 * doc/bison.texinfo (Initial Action Decl): New.
11421 2004-09-20 Akim Demaille <akim@epita.fr>
11423 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
11424 clearer criterion to define it.
11425 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
11426 When reducing on an empty RHS, use the latest stacked location as
11428 yylloc is not always available.
11429 * data/glr.c: Likewise.
11430 Also, honor initial-actions.
11432 2004-09-20 Akim Demaille <akim@epita.fr>
11434 * data/yacc.c (YY_LOCATION_PRINT): New.
11435 Define when we know YYLTYPE's structure, i.e., when the default
11436 YYLLOC_DEFAULT is used.
11437 * data/c.m4 (b4_yysymprint_generate): Use it.
11438 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
11439 value of the result.
11440 (error_start_): Replace with...
11441 (error_range_): this location array.
11442 This allows to replace code relying on the implementation of
11443 locations by portable code.
11444 * data/yacc.c (yylerrsp): Replace with...
11445 (yyerror_range): this.
11446 Every time a token is popped, update yyerror_range[0], to have an
11447 accurate location for the error token.
11448 * data/glr.c (YY_LOCATION_PRINT): New.
11449 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
11450 deference a pointer.
11451 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
11452 report the location in %printers.
11454 * src/scan-skel.l: Instead of abort, report error messages to ease
11455 understanding skeleton scanning failures.
11457 2004-09-16 Akim Demaille <akim@epita.fr>
11459 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
11460 (iterator, const_iterator): these, to be more in the C++ spirit.
11461 Also, return reverse iterators so that when displaying the stack
11462 we display its bottom first.
11463 (Parser::stack_print_, Parser::reduce_print_): Match the messages
11465 We should probably use vector here though.
11467 2004-09-16 Akim Demaille <akim@epita.fr>
11469 Have more complete shift traces.
11471 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
11472 to report Shifts instead of ad hoc YYDPRINTF invocations,
11473 including for the error token.
11474 * data/lalr1.cc (symprint_): Output the location.
11475 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
11476 output the location within the %printer.
11477 Activate GLR tests, at least to make sure they compile properly.
11478 They still don't pass though.
11479 * tests/calc.at: Adjust expect verbose output, since now "Entering
11480 state..." is on a different line than the "Shifting" message.
11482 2004-09-08 Akim Demaille <akim@epita.fr>
11484 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
11485 Bison directive from the Bison file to the invocation of this
11486 macro, so that these directives are passed to
11487 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
11488 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
11489 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11490 the extra Bison directives instead of the whole series.
11491 Change the grammar so that there are recoverable errors, and
11492 unrecoverable errors. Now we can have the parser give up before
11493 consuming the whole input. As a result we now can observe that
11494 the lookahead is freed when needed.
11495 Change the parser source to parse argv[1] instead of a hard coded
11497 Simplify yylex, and give a value and location to EOF.
11498 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11499 passed directives already coded in the file.
11500 Add some tests to check the location of "error".
11501 For some tests, the C++ parser is correct, and not yacc.c.
11502 For other tests, they provide different, but unsatisfying, values,
11503 so keep the C++ value so that at least one parser is "correct"
11504 according to the test suite.
11505 (Actions after errors): Remove, this is subsumed by the
11506 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
11508 2004-09-06 Akim Demaille <akim@epita.fr>
11510 * data/lalr1.cc: Adjust the indentation of the labels.
11511 (Parser::pop): New.
11514 2004-09-06 Akim Demaille <akim@epita.fr>
11516 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
11517 argument, an informative message.
11518 Call YY_SYMBOL_PRINT.
11519 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
11520 * data/lalr1.cc (destruct_): Likewise.
11521 In addition, no longer depend on b4_yysymprint_generate and
11522 b4_yydestruct_generate to generate these functions, do it "by
11525 2004-09-03 Akim Demaille <akim@epita.fr>
11527 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
11528 invoked, yydestruct the lookahead.
11529 * tests/calc.at (Calculator $1): Update the expected lengths of
11530 traces: there is an added line for the discarded lookahead.
11531 * doc/bison.texinfo (Destructor Decl): Some rewording.
11532 Define "discarded" symbols.
11534 2004-09-02 Akim Demaille <akim@epita.fr>
11536 * data/lalr1.cc (translate_, destruct_): No reason to be static.
11538 2004-09-02 Akim Demaille <akim@epita.fr>
11540 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
11541 (YYDSYMPRINTF): Rename as...
11542 (YY_SYMBOL_PRINT): this.
11543 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
11545 Use it instead of direct symprint_ calls.
11546 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
11549 2004-09-02 Akim Demaille <akim@epita.fr>
11551 * data/lalr1.cc (b4_yysymprint_generate): New.
11552 (symprint_): New member function, defined when YYDEBUG.
11553 Use it consistently instead of token/nterm debugging output by
11555 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
11556 %printer calls to use cdebug_ when using lalr1.cc.
11558 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
11560 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
11561 with #ifdef YYDEBUG.
11563 2004-08-26 Akim Demaille <akim@epita.fr>
11565 * doc/bison.texinfo (Implementing Loops): Rename as...
11566 (Implementing Gotos/Loops): this.
11568 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
11570 Adjust to latest gnulib.
11571 * bootstrap (gnulib_modules): Add xalloc-die.
11572 Set LC_ALL=C so that file names sort consistently.
11573 Prefer the gnulib copies of gettext.m4, glibc21.m4,
11574 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
11575 uintmax_t.m4, ulonglong.m4.
11576 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
11577 po.m4 since we are now using _gl.m4 instead.
11579 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
11581 * src/scan-action.l: Remove. Scanning of semantic actions is
11582 handled in scan-gram.l.
11584 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
11586 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
11588 * src/location.h (struct): The file member is a uniqstr.
11589 (equal_boundaries): Use UNIQSTR_EQ for comparison.
11591 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
11593 Fix bug with non-%union parsers that have printers or destructors,
11594 which led to a Bison core dump. Reported by Peter Fales in
11595 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
11597 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
11598 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
11599 not to our own type.
11600 * src/output.c (symbol_destructors_output, symbol_printers_output):
11601 Don't assume %union.
11602 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
11603 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
11604 UNION-FLAG. All callers changed.
11605 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
11606 Use type char, not unsigned int, when declaring an array of char;
11607 this lets us remove a cast.
11608 (Printers and Destructors): Add non-%union test cases.
11610 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11612 * doc/bison.texinfo: Minor editorial changes, mostly to the new
11613 GLR writeups. E.g., avoid frenchspacing and the future tense,
11614 change "lookahead" to "look-ahead", and change "wrt" to "with
11617 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11619 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
11620 New sections, split off from the GLR Parsers section. Put the new
11621 Simple GLR Parser near the start of the GLR section, for clarity.
11622 Rewrite connective text.
11624 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
11626 * doc/bison.texinfo (Simple GLR Parsers): New section.
11628 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
11630 * NEWS, TODO, doc/bison.texinfo:
11631 Use "look-ahead" instead of "lookahead", to be consistent.
11632 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
11633 while we're fixing "look-ahead".
11634 * src/conflicts.c (shift_set): Renamed from shiftset.
11635 (look_ahead_set): Renamed from lookaheadset.
11636 * src/print.c: Likewise.
11637 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
11638 name for "lookahead".

11642 * src/lalr.c (compute_look_ahead_tokens): Renamed from
11643 compute_lookaheads.

11645 (look_ahead_tokens_print): Renamed from lookaheads_print.
11646 * src/state.c (state_rule_look_ahead_tokens_print): Renamed from
11647 state_rule_lookaheads_print.
11648 * src/state.h: Likewise.
11649 (reductions.look_ahead_tokens): Renamed from lookaheads.
11650 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from
11651 AT_DATA_LOOKAHEADS_GRAMMAR.
11653 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
11655 * README: Update location of patched M4 distribution.
11657 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
11659 Don't assume the C++ compiler takes the same arguments as the C compiler
11661 * configure.ac (O0CXXFLAGS): New var.
11662 * tests/atlocal.in (CXXFLAGS): Use it.
11664 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
11666 Fix some "make check" problems with C++ reported by
11667 Albert Chin-A-Young for Tru64 C++ in this thread:
11668 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
11670 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
11671 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11672 Output to a .cc file for C++, not to a .c file.

11674 * tests/regression.at (AT_CHECK_DANCER): Likewise.
11675 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
11677 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
11679 * tests/calc.at, tests/actions.at: Workaround for SGI
11680 C++ compiler. (trivial change)
11682 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
11684 Spent a few hours checking out which prerequisite versions the
11685 current sources actually require. I went all the way back to
11686 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
11687 a seemingly endless set of combinations of versions more recent
11688 than that. The bottom line is that the current sources require
11689 fairly recent versions of the build tools, and it'll be some work
11691 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
11692 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
11693 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
11694 Add comments explaining why those particular versions are
11697 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
11698 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
11699 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
11701 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
11702 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
11704 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11706 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
11707 0.11.5. Suggested by Bruno Haible.
11708 * bootstrap: Remove gettext version checking.
11710 * doc/bison.texinfo (Decl Summary): Also mention that %union
11711 can depend on prerequisite types. Problem reported by Tim
11714 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11716 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
11717 * README-alpha: Don't tell people not to package this.
11719 * bootstrap: Don't assume $(...) works; use `...` instead.
11720 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
11723 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
11724 put into the -d output file, and mention what to do if YYSTYPE is
11725 defined as a macro.
11727 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11729 Undo change made earlier today: it caused autopoint to not bring
11730 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
11733 * bootstrap: Check that gettext version matches what's in
11734 configure.ac. Warn users to ignore robots.txt ERROR 404.
11735 * bootstrap: Undo today's earlier change (logged below).
11736 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
11738 The gettext version checking is causing more trouble than it's
11739 curing; remove it. Problem reported by Paul Hilfinger.
11741 * bootstrap: Issue a warning that one can expect a message
11742 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
11743 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
11745 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
11747 Ensure that the C++ compiler used for testing actually works on a
11748 simple test program; if not, skip the C++-related tests. Problem
11749 reported by Vin Shelton in:
11750 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
11752 * m4/cxx.m4: New file.
11753 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
11754 * tests/atlocal.in (BISON_CXX_WORKS): Add.
11755 * tests/local.at (AT_COMPILE_CXX): Use it.
11757 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
11759 * data/glr.c (yylloc): Output this macro even if locations are not
11760 being generated, as the GLR parser needs it even in that case.
11761 Problem reported by Troy A. Johnson
11762 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
11764 * configure.ac (AC_INIT): Update to 1.875e.
11766 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
11768 * NEWS: Version 1.875d.
11769 * configure.ac (AC_INIT): Likewise.
11770 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
11772 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
11773 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
11774 lalr1.cc runs afoul of the first, and the last two are no longer
11775 supported by GCC 3.4.0.

11822 Get files from the gnulib and po repositories, instead of relying
11823 on them being in our CVS. Upgrade to latest versions of gnulib
11826 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
11827 * bootstrap: Bootstrap from gnulib and po repositories.
11828 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11829 * README-cvs: Document these changes. Remove version numbers from

11893 Remove, as these files are now generated automatically
11894 by bootstrap or automake.
11896 * po/ChangeLog: Remove: all but one entry was a duplicate
11897 of this file, and I moved that 2000-11-02 entry here.

11940 unconditionally. Do not declare perror.

11956 test whether it can stand alone.

11963 the union, because empty unions aren't allowed in C. Caught
11966 2004-04-13 Jim Meyering <jim@meyering.net>
11968 * src/conflicts.c (conflicts_print): Correct format string typo:

12077 $(top_srcdir)/lib and ../lib. This fixes a bug reported
12078 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
12079 There's no need to mention top_builddir since Automake does that
12081 (INCLUDES): Remove, as Automake says it's obsolescent.
12082 Contents migrated into AM_CPPFLAGS as described above.

12098 * config/depcomp, config/install-sh: Sync with Automake 1.8.
12099 * src/output.c (output_skeleton): Rename local var.
12100 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
12101 Bison tokens, as this runs afoul of the 2003-10-07 change that
12102 disallowed NUL bytes in character constants or string literals.
12104 * tests/local.at: Require Autoconf 2.59's Autotest.
12105 * tests/testsuite.at: Don't include local.at, since we now assume
12106 Autoconf 2.59 or later. Autoconf 2.59 had some problems with

12109 multiple inclusion warnings.

12127 literals, unfortunately.
12128 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
12129 Complain about NUL bytes in character constants or string literals.
12131 2003-10-05 Paul Eggert <eggert@twinsun.com>
12133 * NEWS: Don't document %no-default-prec, as it's still
12135 * doc/bison.texinfo: Document %no-default-prec only if
12136 the defaultprec flag is set. Normally it's not.
12138 2003-10-04 Paul Eggert <eggert@twinsun.com>
12140 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
12141 non-modifiable lvalue, instead of a modifiable one.
12142 * doc/bison.texinfo (Actions): Document that $$ can
12143 be assigned to. Do not claim that $$ and $N are

12187 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
12188 "<\#" to avoid magic from Gnus when posting parts of this script.
12190 2003-08-26 Akim Demaille <akim@epita.fr>
12192 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
12193 (Parser::parse): here.
12194 Adjust: nerrs and errstatus is now replaced by...
12195 (Parser::nerrs_, Parser::errstatus_): New.
12197 2003-08-25 Akim Demaille <akim@epita.fr>
12199 * config/announce-gen, Makefile.cfg: New.
12200 * Makefile.am: Adjust.
12201 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
12202 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
12204 2003-08-25 Akim Demaille <akim@epita.fr>
12206 When reducing initial empty rules, Bison parser read an initial
12207 location that is not defined. This results in garbage, and that
12208 affects Bison's own parser. Therefore we need (i) to extend Bison
12209 to support a means to initialize this location, and (ii) to use
12210 this CVS Bison to fix CVS Bison's parser.
12212 * src/reader.h, reader.c (epilogue_augment): Remove, replace
12214 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
12215 * src/parse-gram.y: Adjust.
12216 (%initial-action): New.
12217 (%error-verbose): Since we require CVS Bison, there is no reason
12219 * src/scan-gram.l: Adjust.
12220 * src/Makefile.am (YACC): New, to make sure we use our own parser.
12221 * data/yacc.c (yyparse): Use b4_initial_action.
12223 2003-08-25 Akim Demaille <akim@epita.fr>
12225 * doc/bison.texinfo: Don't promote stdout for error messages.
12227 2003-08-25 Akim Demaille <akim@epita.fr>
12229 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
12230 From Alexandre Duret-Lutz.
12232 2003-08-25 Akim Demaille <akim@epita.fr>
12236 2003-08-25 Akim Demaille <akim@epita.fr>
12238 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
12241 2003-08-25 Akim Demaille <akim@epita.fr>
12243 * data/lalr1.cc (Parser::reduce_print_): New.
12246 2003-08-25 Akim Demaille <akim@epita.fr>
12248 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
12249 error recovery loops. This patch is based on
12250 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
12251 Also, augment the similarity between lalr1.cc and yacc.c.
12252 Note: the locations of error recovery rules are not correct yet.
12254 * data/lalr1.cc: Comment changes to augment the similarity between
12255 lalr1.cc and yacc.c.
12256 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
12257 (yyerrlab1): Remove, but where it used to be (now the bottom part of
12258 yyerrlab), when hitting EOF, pop the whole stack here instead of
12259 merely falling thru the default error handling mechanism.
12260 (yyerrorlab): New label, with the old contents of YYERROR,
12261 plus the following change: pop the stack of rhs corresponding
12262 to the production that invoked YYERROR. That is how Yacc
12263 behaves (required by POSIX).
12264 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
12267 2003-08-25 Akim Demaille <akim@epita.fr>
12269 Tune local.at so that people can "autom4te -l autotest calc.at -o
12270 calc" for instance, to extract a sub test suite.
12272 * tests/testsuite.at: Move the initialization, Autotest version
12273 requirement, and AT_TESTED invocation into...
12274 * tests/local.at: here.
12275 * tests/testsuite.at: Include it for compatibility with Autoconf
12277 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
12280 2003-08-04 Paul Eggert <eggert@twinsun.com>
12282 Rework code slightly to avoid gcc -Wtraditional warnings.
12283 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
12284 The returned value is now stored in *YY0. All callers changed.
12285 * src/output.c (merge_output): Adjust to the above change.
12287 2003-07-26 Paul Eggert <eggert@twinsun.com>
12289 * data/glr.c (YYASSERT): New macro.
12290 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
12291 yyresolveStates, yyprocessOneStack):
12292 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
12293 Derived from a suggestion by Frank Heckenbach.
12295 2003-07-25 Paul Eggert <eggert@twinsun.com>
12297 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
12298 for portability to K&R C (after ansi2knr, presumably). See
12299 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
12300 by Frank Heckenbach, though I have omitted the structure-initialization
12301 part of his glr-knr.diff patch since I recall that the Portable
12302 C Compiler didn't require that change.
12304 Let the user specify how to allocate and free memory.
12305 Derived from a suggestion by Frank Heckenbach in
12306 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
12307 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
12308 All uses of free, malloc, realloc changed to use these macros,
12309 and unnecessary casts removed.
12310 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
12312 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
12314 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
12315 use s.empty() rather than s == "" to test for empty string; see
12316 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
12319 2003-06-25 Akim Demaille <akim@epita.fr>
12321 * config/depcomp, config/install-sh: Update from masters.
12323 2003-06-20 Paul Eggert <eggert@twinsun.com>
12325 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
12326 and return properly parenthesized result.
12327 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
12328 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
12329 Remove unnecessary parentheses from uses.
12330 * doc/bison.texinfo (Location Default Action): Describe the
12331 conventions for parentheses.
12333 2003-06-19 Paul Eggert <eggert@twinsun.com>
12335 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
12336 yyreportTree): Do not assume that size_t is the same width as int,
12337 when printing sizes. Print sizes using an unsigned format.
12338 Problem reported by Frank Heckenbach in
12339 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
12341 Port to Forte Developer 7 C compiler.
12342 * data/glr.c (struct YYLTYPE): If locations are not being used,
12343 declare a single dummy member, as empty structs do not conform
12345 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
12346 the Forte Developer 7 C compiler complains that end-of-loop
12347 code is not reached.
12349 2003-06-17 Paul Eggert <eggert@twinsun.com>
12351 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
12352 avoid warnings from picky compilers about redefinition of PARAMS.
12354 2003-06-17 Paul Eggert <eggert@twinsun.com>
12358 * NEWS: Document 1.875b.
12360 * lib/bbitset.h: Do not include config.h; that's the includer's job.
12361 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
12362 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
12363 Don't use 'index' in comments, as it's a builtin fn on some hosts.
12364 * lib/bitset_stats.c: Include gettext.h unconditionally, as
12365 per recent gettext manual's suggestion.
12366 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
12367 Use prototypes, not old-style definitions.
12368 * lib/lbitset.c (lbitset_unused_clear): Likewise.
12369 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
12370 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,

12378 Do not include <stdlib.h>.
12379 (PARAMS): Define unconditionally for C89.
12380 (ATTRIBUTE_NORETURN): Remove.
12381 (ATTRIBUTE_UNUSED): Define unconditionally.
12383 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
12384 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
12385 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
12386 * lib/vbitset.c, lib/vbitset.h: New files.
12387 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
12388 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
12391 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
12392 `How Can I Reset @code{yyparse}', since texinfo does not allow
12393 arbitrary @ in node names.
12395 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
12396 shouldn't be needed according to the gettext 0.12.1 documentation
12397 but which seem to be needed anyway: codeset.m4 glibc21.m4
12398 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
12399 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
12400 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
12402 * lib/.cvsignore: Add stdbool.h.
12403 * m4/.cvsignore: Add nls.m4, po.m4.
12405 Upgrade to CVS gnulib.
12406 * stdbool_.h: File renamed from stdbool.h.in.
12407 * configure.ac (AM_STDBOOL_H): Invoke this instead of
12409 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
12410 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
12411 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
12412 (MOSTLYCLEANFILES): New var.
12413 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
12414 (stdbool.h): New rule.
12415 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
12416 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
12417 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
12418 m4/quote.m4: Upgrade to today's gnulib.
12420 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
12421 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
12422 the tests right now.
12423 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
12424 yyerror are declared before use; C99 requires this.
12426 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12428 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
12430 (yyrecoverSyntaxError): Correct the logic for setting and testing
12432 Correct comment on handling EOF.
12433 Allow states with only a default reduction, rather than failing
12434 (I can't quite reconstruct why these were not allowed before).
12436 Fixes to avoid problem that $-N rules in GLR parsers can cause
12437 buffer overruns, corrupting state.
12439 * src/output.c (prepare_rules): Output max_left_semantic_context
12441 * src/reader.h (max_left_semantic_context): New variable declaration.
12442 * src/scan-gram.l (max_left_semantic_context): Define.
12443 (handle_action_dollar): Update max_left_semantic_context.
12444 * data/glr.c (YYMAXLEFT): New definition.
12445 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
12446 (yyresolveAction): Ditto.
12448 Fixes to problems with location handling in GLR parsers reported by
12449 Frank Heckenbach (2003/06/05).
12451 * data/glr.c (YYLTYPE): Make trivial if locations not used.
12452 (YYRHSLOC): Add parentheses, and define only if locations used.
12453 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
12454 locations not used.
12455 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
12456 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
12458 * tests/cxx-type.at: Exercise location information; update tests
12459 to differentiate output with and without locations.
12460 Remove forward declarations of yylex and yyerror---caused errors
12461 because default YYLTYPE not yet defined.
12462 Change semantic actions to compute strings, rather than printing
12463 them directly (to test proper passing of semantics values). Change
12464 output to prefix notation and update test data and expected results.
12465 (yylex): Track locations.
12466 (stmtMerge): Return value rather than printing, and include arguments
12469 2003-06-03 Paul Eggert <eggert@twinsun.com>
12471 Avoid warnings generated by GCC 2.95.4 when Bison is
12472 configured with --enable-gcc-warnings.
12473 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
12474 yy::]b4_parser_class_name[::translate_,
12475 yy::Stack::operator[] (unsigned),
12476 yy::Stack::operator[] (unsigned) const,
12477 yy::Slice::operator[] (unsigned),
12478 yy::Slice::operator[] (unsigned) const):
12479 Rename local vars to avoid warnings.
12480 * tests/glr-regression.at (Improper handling of embedded actions
12481 and $-N in GLR parsers): Remove unused local variable from yylex.
12482 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
12483 (void) as arg when not pure, since we now assume C89 when building
12484 Bison. Pacify GCC by using parameter.
12486 2003-06-02 Paul Eggert <eggert@twinsun.com>
12488 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
12489 yy::Location::lines, yy::Location::columns): Rename arguments
12490 to avoid shadowing; this removes a warning generated by GCC 3.3.
12492 2003-06-01 Paul Eggert <eggert@twinsun.com>
12494 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
12495 to g++, as GCC 3.3 complains if you do it.
12496 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
12497 everything that WARNING_CFLAGS has, except omit warnings
12498 not suitable for C++.
12499 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
12500 * tests/atlocal.in (CXXFLAGS): New var.
12501 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
12503 Fix a GLR parser bug I reported in February; see
12504 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
12505 The problem was that GLR parsers did not conform to the C standard,
12506 because actions like { $1 = $2 + $3; } expanded to expressions
12507 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12508 to a local variable. The C standard says that expressions
12509 like (var = f ()) + (var = f ()) have undefined behavior.
12510 Another problem was that GCC sometimes issues warnings that
12511 yyfill and its parameters are unused.
12513 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12514 as possibly unused.
12515 (yyfill): New function.
12517 (yyuserAction): Change type of yynormal to bool, so that it matches
12518 the new yyfill signature. Mark it as possibly unused.
12521 Follow up on a bug I reported in February, where a Bison-generated
12522 parser can loop. Provide a test case and a fix for yacc.c. I
12523 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12524 The original bug report is in:
12525 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
12527 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12528 macro's size was becoming unwieldy.
12529 (yyerrlab): Do not discard an empty lookahead symbol, as this
12530 might destroy garbage.
12531 (yyerrorlab): New label, with the old contents of YYERROR,
12532 plus the following change: pop the stack of rhs corresponding
12533 to the production that invoked YYERROR. That is how Yacc
12534 behaves, and POSIX requires this behavior.
12535 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12536 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12537 Define 'alarm' to do nothing if unistd.h is not available.
12538 Add a new rule "exp: '-' error;" to test the above change to
12539 data/yacc.c. Use 'alarm' to abort any test taking longer than
12540 10 seconds, as it's probably looping.
12541 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12542 Also, the new yacc.c generates two fewer diagnostics for an
12545 2003-05-24 Paul Eggert <eggert@twinsun.com>
12547 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
12548 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
12549 This fixes a problem reported by John Bowman when the Compaq/HP
12550 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
12551 -ansi -Wall -gall).
12552 * data/yacc.c (union yyalloc): Likewise.
12553 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
12555 Switch from 'int' to 'bool' where that makes sense.
12557 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
12558 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,

12560 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
12561 Return or accept bool, not int. All callers changed.

12572 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
12573 bitset_stats_or_and_cmp): Likewise.
12574 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
12575 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
12576 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
12577 ebitset_xor_cmp): Likewise.
12578 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
12579 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
12580 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
12581 lbitset_xor_cmp): Likewise.
12582 * lib/bbitset.h: Include <stdbool.h>.
12583 (struct bitset_vtable): The following members now return bool, not
12584 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
12585 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
12587 * src/conflicts.c (count_rr_conflicts): Likewise.
12588 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
12590 * lib/ebitset.c (ebitset_obstack_init): Likewise.
12591 * lib/lbitset.c (lbitset_obstack_init): Likewise.

12597 graph_flag): Likewise.

12603 (long_options, getargs): Use it.
12604 * src/lalr.c (build_relations): Use bool, not int.
12605 * src/nullable.c (nullable_compute): Likewise.
12606 * src/print.c (print_reductions): Likewise.
12607 * src/tables.c (action_row, pack_vector): Likewise.
12608 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
12609 * src/output.c (prepare): Use it.
12610 * src/output.c (token_definitions_output,
12611 symbol_destructors_output, symbol_destructors_output): Use string,
12612 not boolean integer, to keep track of whether to output separator.
12613 * src/print_graph.c (print_core): Likewise.
12614 * src/state.c (state_rule_lookaheads_print): Likewise.
12616 * config/install-sh: Sync from automake 1.7.5.
12618 2003-05-14 Paul Eggert <eggert@twinsun.com>
12620 * src/parse-gram.y (rules_or_grammar_declaration): Require a
12621 semicolon after a grammar declaration, in the interest of possible
12622 future changes to the Bison input language.
12623 Do not allow a stray semicolon at the start of the grammar.
12624 (rhses.1): Allow one or more semicolons after any rule, including
12625 just before "|" as required by POSIX.
12626 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
12629 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
12631 %parse-param support for lalr1.cc.
12633 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
12634 b4_cc_constructor_calls, b4_cc_constructor_call,
12635 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
12637 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
12638 parse-param arguments.
12639 (yy::b4_parser_class_name): Declare instance variables to
12640 hold parse-param arguments.
12641 * tests/calc.at: s/value/semantic_value/ because value clashes
12642 with a member of yy::b4_parser_class_name. Adjust C++ code
12643 to handle %parse-param. Enable %parse-param test in C++.
12645 2003-05-12 Paul Eggert <eggert@twinsun.com>
12647 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
12648 English a bit. Fix fclose typo. Change "const char" to "char
12649 const", and use ANSI C rather than K&R for "main". Suggest
12650 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
12651 and suggest yy_switch_to_buffer.
12653 2003-05-05 Paul Eggert <eggert@twinsun.com>
12655 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
12656 C89. This avoids a diagnostic on compilers that define __STDC__
12657 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
12658 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12660 2003-05-03 Paul Eggert <eggert@twinsun.com>
12662 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
12663 Do not overrun array bounds.
12664 This should fix a bug reported today by Olatunji Oluwabukunmi in
12665 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
12667 2003-04-29 Akim Demaille <akim@epita.fr>
12669 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
12670 * src/getargs.c, src/getargs.h: here, as bool, not int.
12671 (nondeterministic_parser): New.
12672 * src/parse-gram.y, src/scan-gram.l: Support
12673 %nondeterministic-parser.
12674 * src/output.c (prepare): Use nondeterministic_parser instead
12675 of glr_parser where appropriate.
12676 * src/tables.c (conflict_row, action_row, save_row)
12677 (token_actions, token_actions, pack_vector): Ditto.
12679 2003-04-29 Akim Demaille <akim@epita.fr>
12681 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
12683 2003-04-29 Akim Demaille <akim@epita.fr>
12685 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
12686 with %pure-parser and %locations to exercise the patch from Yakov
12689 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
12691 * data/yacc.c: (b4_lex_param): Corrected for the case where
12692 %lex-param is provided and %pure-parser isn't.
12694 2003-04-27 Paul Eggert <eggert@twinsun.com>
12696 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
12697 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
12698 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
12699 if it is not defined.
12700 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
12702 2003-04-26 Paul Eggert <eggert@twinsun.com>
12704 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
12705 Declare to be of type suitable for the ninf value itself, not of
12706 type suitable for the corresponding table, since the latter might
12707 be unsigned but the ninf value might be negative. This fixes a
12708 bug reported by Alexandre Duret-Lutz in
12709 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
12711 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
12712 invokes it. We shouldn't invoke it twice because it will attempt
12713 to put error.o in the archive twice. This fixes a glitch reported
12714 by Martin Mokrejs in
12715 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
12717 2003-04-21 Paul Eggert <eggert@twinsun.com>
12719 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
12722 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
12724 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
12725 Fix obvious typo that results in uncompilable GLR parsers
12726 when both %pure-parser and %locations are used. (trivial change)
12728 2003-04-17 Paul Eggert <eggert@twinsun.com>
12730 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
12731 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
12732 Do not insert the expected token via unput, as this runs afoul
12733 of a POSIX-compatibility bug in flex 2.5.31.
12734 All uses changed to BEGIN the parent state,
12735 since we no longer insert the expected token via unput.
12736 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
12737 that is no longer emitted after the above change.
12739 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
12740 the first one. This change is from Paul Hilfinger, and it fixes
12741 regression reported by Werner Lemberg in
12742 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
12744 (resolve_sr_conflict): Don't invoke state_errs_set
12745 unless one or more tokens have been explicitly made errors.
12746 Otherwise, the above change causes Bison to abort.
12748 * tests/existing.at (GNU pic Grammar): New test case, taken from
12751 2003-03-31 Akim Demaille <akim@epita.fr>
12753 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
12755 2003-03-31 Akim Demaille <akim@epita.fr>
12757 * src/output.c (prepare_symbols): Avoid trailing spaces in the
12760 2003-03-31 Akim Demaille <akim@epita.fr>
12762 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
12763 From Paul Hilfinger.
12765 2003-03-29 Akim Demaille <akim@epita.fr>
12767 * m4/error.m4: Do not put under dynamic conditions some code which
12768 expansion is under static control.
12770 2003-03-29 Akim Demaille <akim@epita.fr>
12772 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
12774 2003-03-29 Akim Demaille <akim@epita.fr>
12776 * doc/bison.texinfo (Strings are Destroyed): New.
12778 2003-03-13 Paul Eggert <eggert@twinsun.com>
12780 * .cvsignore: Add configure.lineno.
12781 * src/.cvsignore: Add yacc.
12782 * tests/.cvsignore: Add testsuite.log.
12783 * doc/fdl.texi: Sync with latest FSF version.
12785 2003-03-12 Paul Eggert <eggert@twinsun.com>
12787 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
12788 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
12789 cursor, instead of leaving it undefined. This fixes a bug
12790 reported by Tim Van Holder in
12791 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
12792 * tests/input.at (Torturing the Scanner): Test the scanner on
12793 an empty input file, which was Tim Van Holder's test case.
12795 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
12796 <sys/resource.h> can be included, include sys/time.h and
12797 sys/times.h first, if available. This works around the SunOS
12798 4.1.4 porting bug reported by Bruce Becker in
12799 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
12801 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
12802 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
12803 AC_HEADER_SYS_WAIT.
12805 Merge changes from gnulib. This was prompted because the CVS
12806 snapshot didn't build on Solaris 7 due to strnlen problems.
12808 These changes need to be merged back into gnulib:
12809 * lib/hash.c: Include <stdbool.h> unconditionally.
12810 * m4/onceonly.m4 (m4_quote): New macro.
12811 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
12812 Quote AC_FOREACH variable-expansions properly.
12813 The 2003-01-03 obstack.h change also needs merging.
12814 {end of changes requiring merging}
12816 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
12817 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
12818 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
12819 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
12820 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
12821 New files, imported from gnulib.
12822 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
12825 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
12826 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
12829 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
12831 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
12832 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
12833 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
12834 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
12835 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
12836 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
12837 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
12838 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
12839 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
12840 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
12841 (jm_PREREQ_ARGMATCH): Remove.
12842 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
12843 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
12845 * src/system.h: Include <stdbool.h> unconditionally.
12847 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
12848 assuming at least C89 in the bitset code for some time now.
12850 2003-03-03 Akim Demaille <akim@epita.fr>
12854 2003-03-02 Akim Demaille <akim@epita.fr>
12856 * doc/bison.texinfo (Table of Symbols): Reactivate the
12857 documentation for %lex-param, and %parse-param.
12859 2003-03-02 Akim Demaille <akim@epita.fr>
12861 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
12862 generate verbose error messages.
12863 Use the number of tokens as an upper bound in yytname, as it
12864 cannot be a non terminal.
12866 2003-03-02 Akim Demaille <akim@epita.fr>
12868 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
12871 2003-03-02 Akim Demaille <akim@epita.fr>
12873 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
12874 Use them to exercise yycheck overrun.
12875 Based on Andrew Suffield's grammar.
12877 2003-03-02 Akim Demaille <akim@epita.fr>
12879 Create tests/local.at for Bison generic testing macros.
12881 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
12882 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
12884 * tests/calc.at (AT_CHECK_CALC): Adjust.
12885 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
12886 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
12887 * tests/local.at: here.
12888 (AT_COMPILE_CXX): Tags the tests using it as c++.
12889 Ignore the test if CXX is not functional.
12891 2003-03-01 Paul Eggert <eggert@twinsun.com>
12893 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12894 not loc->end, since loc->end might contain garbage and this leads
12895 to undefined behavior on some platforms.
12896 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12897 depend on *loc, so that the reader doesn't give the the false
12898 impression that *loc is initialized.
12899 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12900 does not survive the return.
12902 2003-03-01 Akim Demaille <akim@epita.fr>
12904 * src/scan-gram.l (code_start): Always initialize it when entering
12905 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12906 yylex invocation. An alternative would be making it static, but
12907 then it starts with the second %%'s beginning, instead of its end.
12909 2003-02-28 Paul Eggert <eggert@twinsun.com>
12911 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12912 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12913 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12915 2003-02-26 Paul Eggert <eggert@twinsun.com>
12917 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12918 Remove Sequent/Pyramid discussion (nobody uses them any more).
12919 Merge VMS and MS-DOS discussion; these ports may well be dead
12920 but let's keep mentioning them for now. Put <> around email
12921 addresses. Add copyright notice.
12923 2003-02-24 Paul Eggert <eggert@twinsun.com>
12925 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12926 to avoid collision with flex use of yylineno.
12927 Problem reported by Bruce Lilly in
12928 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
12929 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
12930 * data/yacc.c (yy_reduce_print): Likewise.
12932 * config/depcomp: Sync with Automake 1.7.3.
12934 2003-02-21 Akim Demaille <akim@epita.fr>
12936 * data/lalr1.cc: Use temporary variables instead of casts to
12937 change integer types.
12938 Suggested by Paul Eggert.
12940 2003-02-21 Akim Demaille <akim@epita.fr>
12942 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12943 to avoid confusions with lalr1.cc's notion of Position.
12944 Suggested by Paul Eggert.
12946 2003-02-20 Akim Demaille <akim@epita.fr>
12948 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12949 before initial_columns.
12950 (location.hh): Use consistent variable names when defining the
12952 Use "last" so that we subtract from Positions, not from unsigned.
12954 2003-02-20 Akim Demaille <akim@epita.fr>
12956 * data/lalr1.cc (position.hh): New subfile, including the extended
12957 and Doxygen'ed documentation of class Position.
12958 (location.hh): Use it.
12959 Document a` la Doxygen.
12960 With the help of Benoit Perrot.
12962 2003-02-20 Akim Demaille <akim@epita.fr>
12964 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
12966 Redefine AT_YYERROR_SEES_LOC_IF using it.
12967 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
12969 Don't use the location in yy::Parser::error_ and
12970 yy::Parser::print_ when not %locations.
12971 Activate more lalr1.cc tests.
12973 2003-02-19 Akim Demaille <akim@epita.fr>
12975 * data/lalr1.cc: When displaying a line number, be sure to make it
12978 2003-02-19 Akim Demaille <akim@epita.fr>
12980 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12982 (YYABORT, YYACCEPT, YYERROR): New.
12983 * tests/calc.at: Renable the lalr1.cc test.
12985 2003-02-19 Akim Demaille <akim@epita.fr>
12987 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12988 error recovery, mixing with/without pops and discarding of the
12991 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
12993 2003-02-17 Paul Eggert <eggert@twinsun.com>
12995 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
12996 * tests/testsuite.at (AT_COMPILE): Use them.
12997 This fixes the testsuite problem reported by Robert Lentz in
12998 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
13000 2003-02-12 Paul Eggert <eggert@twinsun.com>
13002 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
13003 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
13004 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
13005 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
13006 Check for malloc failure, for consistency with yacc.c.
13007 (yytname_size): Remove, for consistency with yacc.c.
13009 The bug still remains in data/lalr1.cc, as I didn't have time
13012 2003-02-06 Akim Demaille <akim@epita.fr>
13014 * configure.ac (GXX): Rename as...
13015 (CXX): this, to keep the original Autoconf semantics.
13017 * data/lalr1.cc: Fix b4_copyright invocations.
13018 If YYDEBUG is not defined, don't depend upon name_ being defined.
13019 (location.hh): Include string and iostream.
13020 (Position::filename): New member.
13021 (Position::Position ()): New.
13022 (operator<< (Position)): New.
13023 (operator- (Position, int)): New.
13024 (Location::first, Location::last): Rename as...
13025 (Location::begin, Location::end): these, to mock the conventional
13027 (operator<< (Location)): New.
13028 * tests/atlocal.in (CXX): New.
13029 * tests/testsuite.at (AT_COMPILE_CXX): New.
13030 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
13031 locations in a more synthetic way.
13032 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
13034 Adjust the C locations to match those from Emacs: first column is
13036 Change all the expected results.
13037 Conform to the GCS: simplify the locations when applicable.
13038 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
13039 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
13040 these CPP macros with the m4 macros new defined by...
13041 (AT_CHECK_PUSHDEFS): this, i.e.:
13042 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
13043 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
13045 (AT_CHECK_POPDEFS): Undefine them.
13046 (AT_CHECK_CALC_LALR1_CC): New.
13047 Use it for the first lalr1.cc test.
13049 2003-02-04 Akim Demaille <akim@epita.fr>
13051 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
13052 Location as is defined.
13054 2003-02-04 Akim Demaille <akim@epita.fr>
13056 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
13057 name_ being defined.
13059 2003-02-03 Paul Eggert <eggert@twinsun.com>
13061 * src/gram.h (start_symbol): Remove unused decl.
13063 Use more-consistent naming conventions for local vars.
13065 * src/derives.c (derives_compute): Change type of local var from
13066 int to rule_number.
13067 * src/gram.c (grammar_rules_partial_print): Likewise.
13068 * src/print.c (print_core): Likewise.
13069 * src/reduce.c (reduce_grammar_tables): Likewise.
13071 * src/gram.c (grammar_dump): Change name of item_number *
13072 local var from r to rp.
13073 * src/nullable.c (nullable_compute): Likewise.
13075 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
13077 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
13078 for symbol or symbol_number var.
13079 * src/reader.c (grammar_start_symbol_set): Likewise.
13080 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
13082 * src/state.c (transitions_to): Likewise.
13083 * src/state.h: Likewise.
13084 * src/tables.c (symbol_number_to_vector_number): Likewise.
13086 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
13089 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
13092 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
13095 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
13096 Use str, not s, for char * var. Use ch, not c, for character var.
13097 Use size for size var.
13099 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
13101 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
13103 * src/uniqstr.h: Likewise.
13105 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13106 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13107 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
13108 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
13109 param to have same name as that of enum, so that we don't use
13110 "s" to stand for a non-state.
13112 2003-02-02 Akim Demaille <akim@epita.fr>
13114 * src/scan-skel.l: Scan more than one inert character per yylex
13117 2003-02-01 Paul Eggert <eggert@twinsun.com>
13121 * po/LINGUAS: Add ms.
13123 2003-01-30 Akim Demaille <akim@epita.fr>
13125 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
13127 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13129 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
13132 Changes in response to error report by S. Eken: GLR mode does not
13133 handle negative $ indices or $ indices in embedded rules correctly.
13134 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
13136 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
13137 (b4_rhs_location): Ditto.
13138 (yyfill): New function to copy from stack tree into array
13140 (yyuserAction): Modify to allow incremental move of semantic values
13141 to rhs array when in GLR mode.
13142 Define YYFILL to use in user-defined actions to fill semantic array
13144 Remove dummy use of yystack, as there is now a guaranteed use.
13145 (yydoAction): Modify to allow incremental move of semantic values
13146 to rhs array when in GLR mode.
13147 (yyresolveAction): Ditto.
13148 (yyglrShiftDefer): Update comment.
13149 (yyresolveStates): Use X == NULL for pointers, not !X.
13150 (yyglrReduce): Ditto.
13151 (yydoAction): Ditto
13153 * tests/glr-regr1.at: Rename to ...
13154 * tests/glr-regression.at: Add new regression test for the problems
13155 described above (adapted from S. Eken).
13156 Update copyright notice.
13157 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
13158 * tests/Makefile.am: Ditto.
13160 2003-01-28 Paul Eggert <eggert@twinsun.com>
13162 * data/lalr1.cc: Do not use @output_header_name@ unless
13163 b4_defines_flag is set. This fixes two bugs reported by
13165 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
13166 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
13168 2003-01-21 Paul Eggert <eggert@twinsun.com>
13170 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
13171 we don't need to worry about yyerrlab1 being reported as an
13172 "unused label" by non-GCC C compilers. The downside is that if
13173 locations are used then a couple of statements are duplicated each
13174 time YYERROR is invoked, but the upside is that the warnings
13176 (yyerrlab1): Move code to YERROR.
13177 (yyerrlab2): Remove. Change uses back to yyerrlab1.
13178 This reverts some of the 2002-12-27 change.
13180 2003-01-17 Paul Eggert <eggert@twinsun.com>
13182 * src/output.c (symbol_printers_output): Fix typo that led
13183 to core dump. Problem reported by Antonio Rus in
13184 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
13186 2003-01-13 Akim Demaille <akim@epita.fr>,
13187 Quoc Peyrot <chojin@lrde.epita.fr>,
13188 Robert Anisko <anisko_r@lrde.epita.fr>
13190 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
13191 when the stacks contain one element, as the loop would otherwise
13192 free the last state, and then use the top state (the one we just
13193 popped). This means that the initial elements will not be freed
13194 explicitly, as is the case in yacc.c; it is not a problem, as
13195 these elements have fake values.
13197 2003-01-11 Paul Eggert <eggert@twinsun.com>
13199 * NEWS: %expect-violations are now just warnings, reverting
13200 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
13201 bootstrapping problem reported by Matthias Klose; see
13202 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
13203 * src/conflicts.c (conflicts_print): Likewise.
13204 * tests/conflicts.at (%expect not enough, %expect too much,
13205 %expect with reduce conflicts): Likewise.
13206 * doc/bison.texinfo (Expect Decl): Document this. Also mention
13207 that the warning is enabled if the number of conflicts changes
13208 (not necessarily increases).
13210 * src/getargs.c (version): Update copyright year.
13212 2003-01-09 Akim Demaille <akim@epita.fr>
13214 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
13216 2003-01-08 Paul Eggert <eggert@twinsun.com>
13218 * Makefile.maint (WGETFLAGS):
13219 New macro, containing "-C off" to disable proxy caches.
13220 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
13221 (rel-check): Use $(WGET) instead of wget.
13223 2003-01-06 Paul Eggert <eggert@twinsun.com>
13225 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
13226 the GLR paper of Scott, Johnstone and Hussain.
13228 2003-01-04 Paul Eggert <eggert@twinsun.com>
13230 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
13231 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
13232 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
13233 (EXTRA_LIBRARIES): New var, for liby.a.
13234 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
13235 (EXTRA_SCRIPTS): New var, for yacc.
13237 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
13238 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
13239 Problem reported by Nelson H. F. Beebe.
13241 2003-01-03 Paul Eggert <eggert@twinsun.com>
13243 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
13244 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
13245 when compiling Bison 1.875's `bitset bset = obstack_alloc
13246 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
13248 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
13249 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
13250 grow to a huge size with typical invocation.
13252 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
13253 Use the pattern recommended by Autoconf 2.57, except also protect
13254 against double-definition.
13255 * src/system.h: Likewise.
13256 Portability issues reported by Nelson H. F. Beebe.
13258 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
13259 All uses changed. Provide a definition in both C and C++.
13260 (yytrue, yyfalse): Define even if defined (__cplusplus).
13262 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
13263 Reported by Nelson H. F. Beebe.
13265 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
13267 2003-01-02 Paul Eggert <eggert@twinsun.com>
13269 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
13270 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
13271 Bug reported by Nelson H. F. Beebe.
13273 2003-01-01 Paul Eggert <eggert@twinsun.com>
13277 2002-12-30 Paul Eggert <eggert@twinsun.com>
13279 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
13281 (<INITIAL>","): Here. This causes stray "," to be treated
13284 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
13285 last brace in braced code when not in Yacc mode, for compatibility
13286 with Bison 1.35. This resurrects the 2001-12-15 patch to
13289 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
13290 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
13292 2002-12-28 Paul Eggert <eggert@twinsun.com>
13294 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
13295 that of SYM's type. This fixes Debian bug 168069, reported by
13298 2002-12-28 Paul Eggert <eggert@twinsun.com>
13302 Switch back to the Yacc style of conflict reports, undoing some
13303 of the 2002-07-30 change.
13304 * doc/bison.texinfo (Understanding): Use Yacc style for
13305 conflict reports. Also, use new way of locating rules.
13306 * src/conflicts.c (conflict_report):
13307 Renamed from conflict_report_yacc, removing the old
13308 'conflict_report'. Translate the entire conflict report at once,
13309 so that we don't assume that "," has the same interpretation in
13311 (conflicts_output): Use Yacc-style conflict report for each state,
13312 instead of our more-complicated style.
13313 (conflicts_print): Use Yacc-style conflict report, except print
13314 the input file name when not emulating Yacc.
13315 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
13316 Conflicted Reduction, %expect not enough, %expect too much,
13317 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
13318 * tests/existing.at (GNU Cim Grammar): Likewise.
13319 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
13321 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
13322 fatal): Don't invoke fflush; it's not needed and it might even be
13323 harmful for stdout, as stdout might not be open.
13324 * src/reduce.c (reduce_print): Likewise.
13326 2002-12-27 Paul Eggert <eggert@twinsun.com>
13328 Fix a bug where error locations were not being recorded correctly.
13329 This problem was originally reported by Paul Hilfinger in
13330 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
13332 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13333 top of the location stack's error locations.
13334 (yyerrlab): Set it. When discarding a token, push its location
13335 onto yylerrsp so that we don't lose track of the error's end.
13336 (yyerrlab1): Now is only the target of YYERROR, so that we can
13337 properly record the location of the action that failed. For GCC
13338 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13339 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13340 (yyerrlab2): New label, which yyerrlab now falls through to.
13341 Compute the error's location by applying YYLLOC_DEFAULT to
13342 the locations of all the symbols that went into the error.
13343 * doc/bison.texinfo (Location Default Action): Mention that
13344 YYLLOC_DEFAULT is also invoked for syntax errors.
13345 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13346 Error locations include the locations of all the tokens that were
13347 discarded, not just the last token.
13349 2002-12-26 Paul Eggert <eggert@twinsun.com>
13351 * src/files.c: Include quote.h.
13352 (compute_output_file_names): Warn if we detect conflicting
13353 outputs to the same file. This should catch the misunderstanding
13354 exemplified by Debian Bug 165349, reported by Bruce Stephens..
13356 * src/conflicts.c (conflicts_print): If the user specifies
13357 "%expect N", report an error if there are any reduce/reduce
13358 conflicts. This is what the manual says should happen.
13359 This fixes Debian bug 130890, reported by Anthony DeRobertis.
13360 * tests/conflicts.at (%expect with reduce conflicts): New test.
13362 Don't use m4_include on relative file names, as it doesn't work as
13363 desired if there happens to be a file with that name under ".".
13365 * m4sugar/version.m4: Remove; it was included but it wasn't used.
13366 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
13367 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
13368 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
13369 * src/output.c (output_skeleton): Use full path names when
13370 specifying a file to include; don't rely on include path, as
13371 it's unreliable when the working file contains a file with
13374 2002-12-25 Paul Eggert <eggert@twinsun.com>
13376 Remove obsolete references to bison.simple and bison.hairy.
13377 Problem mentioned by Aubin Mahe in
13378 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
13379 * data/glr.c: Comment fix.
13380 * doc/bison.1: Remove references. Also, mention "yacc".
13382 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
13385 * src/parse-gram.y (declaration): Use enum "report_states" rather
13386 than its numeric value 1.
13388 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
13389 opening a new one. This fixes Debian bug 165349, reported by
13392 2002-12-24 Paul Eggert <eggert@twinsun.com>
13396 * Makefile.maint (cvs-update): Don't assume that the shell
13397 supports $(...), as Solaris sh doesn't.
13399 * src/parse-gram.y (lloc_default): Remove test for empty
13400 nonterminals at the end, since it didn't change the result.
13402 2002-12-24 Paul Eggert <eggert@twinsun.com>
13404 If the user does not define YYSTYPE as a macro, Bison now declares it
13405 using typedef instead of defining it as a macro. POSIX requires this.
13406 For consistency, YYLTYPE is also declared instead of defined.
13408 %union directives can now have a tag before the `{', e.g., the
13409 directive `%union foo {...}' now generates the C code
13410 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13411 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13412 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13413 instead of `yyltype'.
13415 `yystype' and `yyltype' are now obsolescent macros instead of being
13416 typedefs or tags; they are no longer documented and will be
13417 withdrawn in a future release.
13419 * data/glr.c (b4_location_type): Remove.
13420 (YYSTYPE): Renamed from yystype.
13421 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
13422 (struct YYLTYPE): Renamed from struct yyltype.
13423 (YYLTYPE): Renamed from yyltype.
13424 (yyltype, yystype): New (and obsolescent) macros,
13425 for backward compatibility.
13426 * data/yacc.c: Likewise.
13428 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13429 does not specify a union tag. This is for compatibility with
13432 * src/parse-gram.y (add_param): 2nd arg is now char * not char
13433 const *, since it is now modified by stripping surrounding { }.
13434 (current_braced_code): Remove.
13435 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
13436 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
13437 trailing " {...}". Now of type <chars>.
13438 (grammar_declaration): Adjust to bundled tokens.
13439 (code_content): Remove; stripping is now done by add_param.
13440 (print_token_value): Print contents of bundled tokens.
13441 (token_name): New function.
13443 * src/reader.h (braced_code, current_braced_code): Remove.
13444 (token_name): New decl.
13446 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
13447 token_type, not braced_code code_kind. All uses changed.
13448 (SC_PRE_CODE): New state, for scanning after a keyword that
13449 has (or usually has) an immediately-following braced code.
13450 (token_type): New local var, to keep track of which token type
13451 to return when scanning braced code.
13452 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
13453 <INITIAL>"%parse-param", <INITIAL>"%printer",
13454 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
13455 instead of returning a token type immediately.
13456 (<INITIAL>"{"): Set token type.
13457 (<SC_BRACED_CODE>"}"): Use it.
13458 (handle_action_dollar, handle_action_at): Now returns bool
13459 indicating success. Fail if ! current_rule; this prevents a core dump.
13460 (handle_symbol_code_dollar, handle_symbol_code_at):
13461 Remove; merge body into caller.
13462 (handle_dollar, handle_at): Complain in invalid contexts.
13464 * NEWS, doc/bison.texinfo: Document the above.
13465 * NEWS: Fix years and program names in copyright notice.
13467 2002-12-17 Paul Eggert <eggert@twinsun.com>
13469 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
13470 Reporting, Table of Symbols): Omit mentions of %lex-param and
13471 %parse-param from the documentation for now.
13473 2002-12-15 Paul Eggert <eggert@twinsun.com>
13475 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
13476 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
13477 lookahead symbol, and which sets yychar in parser actions) and it
13478 disagreed with the Bison documentation. Bug
13479 reported by Andrew Walrond.
13481 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
13482 as the caller now does that.
13483 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
13484 (YYEMPTY): Parenthesize right hand side, since others use it.
13485 (yyparse): Don't assume that our generated code is the only code
13488 2002-12-13 Paul Eggert <eggert@twinsun.com>
13492 POSIX requires a "yacc" command.
13493 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
13494 (MOSTLYCLEANFILES): Add yacc.
13496 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
13497 as an alias for bison y.
13499 * po/LINGUAS: Add da.
13501 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
13502 problem with latest <getopt.h>.
13503 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
13505 * doc/fdl.texi: Upgrade to 1.2.
13506 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
13507 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
13508 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
13510 * config/install-sh: Sync with autotools.
13512 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
13513 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13514 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
13515 locations are requested.
13516 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
13517 locations are requested.
13519 2002-12-12 Paul Eggert <eggert@twinsun.com>
13521 Remove unportable casts and storage allocation tricks.
13522 While we're at it, remove almost all casts, since they
13523 usually aren't needed and are a sign of trouble.
13525 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13527 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13528 the pointer DSET returned by malloc; this isn't portable.
13529 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13530 Similarly for DERIVES.
13531 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
13532 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.

13539 rather than XMALLOC (char, N).
13541 * src/files.c (filename_split): Rewrite to avoid cast.

13546 Now inline functions rather than macros, to avoid casts.
13547 * src/state.h (state_number_as_int): Likewise.
13548 * src/tables.c (state_number_to_vector_number,
13549 symbol_number_to_vector_number): Likewise.
13551 * src/gram.h (int_of_rule_number): Remove; no longer used.
13553 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
13554 since the resulting storage is always stored into.
13556 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
13559 * src/muscle_tab.c (muscle_m4_output):
13560 Now inline. Return bool, not int.
13561 * src/state.c (state_compare): Likewise.
13562 * src/symtab.c (symbol_check_defined,
13563 symbol_check_alias_consistency, symbol_pack, symbol_translation,

13571 symbol_check_alias_consistency_processor, symbol_pack_processor,
13572 symbol_translation_processor, hash_symbol_comparator,
13573 hash_symbol_hasher): Likewise.
13574 * src/uniqstr.c (uniqstr_print_processor): Likewise.
13575 * src/muscle_tab.c (muscles_m4_output):
13576 Use new functions instead of casting old functions unportably.
13577 * src/state.c (state_hash_new): Likewise.
13578 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
13579 symbols_token_translations_init):
13581 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
13583 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13584 var instead of casting to long, to avoid casts.
13585 (prepare_states): Use MALLOC rather than alloca, so that we don't
13586 have to worry about alloca.
13587 * src/state.c (state_hash_lookup): Likewise.
13589 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
13590 local var instead of casting to unsigned char, to avoid casts.
13592 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
13593 STATE_ALLOC): Remove.
13594 (transitions_new, errs_new, reductions_new, state_new): Use malloc
13595 rather than calloc, and use offsetof to avoid allocating slightly
13597 (state_new): Initialize all members.
13599 * src/state.c (state_hash): Use unsigned accumulator, not signed.
13601 * src/symtab.c (symbol_free): Remove; unused.
13602 (symbol_get): Remove cast in lhs of assignment.
13603 (symbols_do): Now static. Accept generic arguments, not
13604 hashing-related ones.
13606 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
13607 (symbol_processor): Remove.
13608 (symbols_do): Remove decl; now static.
13610 * src/system.h (alloca): Remove; decl no longer needed.
13611 (<stddef.h>): Include, for offsetof.
13612 (<inttypes.>, <stdint.h>): Include if available.
13613 (uintptr_t): New type, if system lacks it.
13614 (CALLOC, MALLOC, REALLOC): New macros.
13615 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
13618 * src/tables.c (table_size): Now int, to pacify GCC.
13619 (table_grow, table_ninf_remap): Use signed table size.
13620 (save_row): Don't bother initializing locals when not needed.

13629 * src/getargs.c (getargs): Don't assume EOF == -1.
13631 2002-12-09 Paul Eggert <eggert@twinsun.com>
13633 Change identifier spellings to avoid collisions with names
13634 that are reserved by POSIX.
13636 Don't use names ending in _t, since POSIX reserves them.
13637 For consistency, remove _e and _s endings -- they're weren't
13638 needed to remove ambiguity. All uses changed.
13639 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
13640 turn was just renamed from struniq_t.
13641 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
13642 which in turn was just renamed from struniq_processor_t.
13643 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
13644 in turn was renamed from hash_compare_struniq_t.

13713 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
13714 value_t_as_yystype -> value_as_yystype.
13716 Don't include <errno.h> in the mainstream code, since it
13717 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
13718 * lib/get-errno.c, lib/get-errno.h: New files.
13719 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
13721 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
13722 * src/output.c (output_skeleton): Likewise.

13729 (TAB_EXT): Renamed from EXT_TAB.
13730 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
13732 Avoid str[a-z]*, since <string.h> reserves that name space.
13733 Change all instances of "struniq" in names to "uniqstr", and
13734 likewise for "STRUNIQ" and "UNIQSTR".
13735 * src/uniqstr.c: Renamed from src/struniq.c.
13736 * src/uniqstr.h: Renamed from src/struniq.h.
13737 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
13738 * src/files.c (strsuffix): Remove; unused.

13740 * src/files.h (strsuffix, stringappend): Remove; unused.
13741 * src/parse-gram.y (<chars>): Renamed from <string>.

13747 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
13748 (N_EXPAND): Renamed from N_STRETCH.

13752 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
13754 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.
13755 * src/state.h (STATE_NUMBER_MAXIMUM): Renamed from STATE_NUMBER_MAX.
13756 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.
13757 * src/tables.c (VECTOR_NUMBER_MAX, VECTOR_NUMBER_MIN): Remove; unused.
13758 (BASE_MAXIMUM): Renamed from BASE_MAX.
13759 (BASE_MINIMUM): Renamed from BASE_MIN.
13760 (ACTION_MAX): Remove; unused.
13761 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
13762 Unnecessary casts removed from above defines.
13765 Fix misspelling in names.
13766 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
13767 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
13771 * lib/timevar.c (timevar_report): Renamed from time_report,
13772 for consistency with other names.
13773 * lib/timevar.h (timevar_report): New decl.
13774 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
13777 Sort include-file uses.
13779 Reorder all include files under src to be in the order "system.h".
13780 then the ../lib include files in angle brackets (alphabetized),
13781 then the . include files in double-quotes (alphabetized). Fix
13782 dependency breakages encountered in this process, as follows:
13783 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
13784 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
13785 * src/state.h: Include "symtab.h".
13787 2002-12-08 Paul Eggert <eggert@twinsun.com>
13789 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
13790 since this causes problems when __file__ contains character
13791 sequences like "@" that are treated specially by src/scan-skel.l.
13792 Instead, just use the file's basename. This fixes the bug
13793 reported by Martin Mokrejs in
13794 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
13796 2002-12-06 Paul Eggert <eggert@twinsun.com>
13798 Add support for rules that do not have trailing semicolons, as
13799 POSIX requires. Improve the quality of locations in Bison
13802 * src/location.c: Include <quotearg.h>.
13803 (empty_location): Now const.
13804 (location_print): New function. Follow the recommendation of the
13805 GNU Coding Standards for locations that span file boundaries.
13806 * src/location.h: Do not include <quotearg.h>; no longer needed.
13807 (boundary): New type.
13808 (location_t): Use it. This allows locations to span file boundaries.
13809 All member uses changed: file -> start.file or end.file (as needed),
13810 first_line -> start.line, first_column -> start.column,
13811 last_line -> end.line, last_column -> end.column.
13812 (equal_boundaries): New function.
13813 (LOCATION_RESET, LOCATION_STEP): Remove.
13814 (LOCATION_PRINT): Remove. All callers changed to use location_print.
13815 (empty_location): Now const.
13816 (location_print): New decl.
13817 * src/parse-gram.y (lloc_default): New function, which handles
13818 empty locations more accurately.
13819 (YYLLOC_DEFAULT): Use it.
13820 (%token COLON): Remove.
13821 (%token ID_COLON): New token.
13823 (declarations, rules): Remove trailing semicolon.
13824 (declaration, rules_or_grammar_declaration):
13825 Allow empty (";") declaration.
13826 (symbol_def): Remove empty actions; no longer needed.
13827 (rules_or_grammar_declaration): Remove trailing semicolon.
13828 (semi_colon.opt): Remove.
13829 * src/reader.h: Include location.h.
13830 (scanner_cursor): New decl.
13831 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
13833 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
13835 (STEP): Remove. No longer needed, now that adjust_location does
13836 the work. All uses removed.
13837 (scanner_cursor): New var.
13838 (adjust_location): Renamed from extend_location. It now sets
13839 *loc and adjusts the scanner cursor. All uses changed.
13840 Don't bother testing for CR.
13841 (handle_syncline): Remove location arg; now updates scanner cursor.
13842 All callers changed.
13843 (unexpected_end_of_file): Now accepts start boundary of token or
13844 comment, not location. All callers changed. Update scanner cursor,
13846 (SC_AFTER_IDENTIFIER): New state.
13847 (context_state): Renamed from c_context. All uses changed.
13848 (id_loc, code_start, token_start): New local vars.
13849 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
13850 processing of Yacc white space and equivalents here.
13851 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
13852 instead of returning ID immediately, since we need to search for
13853 a subsequent colon.
13854 (<INITIAL>"'", "\""): Save token_start.
13855 (<INITIAL>"%{", "{", "%%"): Save code_start.
13856 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
13857 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
13858 BEGIN context_state at end, not INITIAL.
13859 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
13860 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
13861 Return correct token start.
13862 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
13863 the start of a character, string or multiline comment is found.
13864 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
13865 Reduction): Adjust reported locations to match the more-precise
13866 results now expected.
13867 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
13868 * tests/reduce.at (Useless Rules, Reduced Automaton,
13869 Underivable Rules): Likewise.
13870 * tests/regression.at (Invalid inputs): No longer `expecting ";"
13871 or "|"' now that so many other tokens are allowed by the new grammar.
13873 * src/complain.h (current_file): Remove duplicate decl;
13874 current_file is now owned by files.h.
13875 * src/complain.c, src/scan-gram.l: Include files.h.
13877 2002-12-06 Paul Eggert <eggert@twinsun.com>
13879 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
13880 promotes to int; it might be unsigned int.
13881 * data/yacc.c (yy_reduce_print): Likewise.
13883 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
13884 be #defined in the prologue, not in the Bison declarations.
13885 This fixes Debian Bug 102878, reported by Shaul Karl.
13887 2002-12-02 Paul Eggert <eggert@twinsun.com>
13889 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
13890 * lib/strtoul.c: New file, from gnulib.
13891 This fixes a porting bug reported by Peter Klein in
13892 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13894 2002-11-30 Paul Eggert <eggert@twinsun.com>
13896 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13897 and put only a forward declaration in the prologue. This is for
13898 consistency with the other scanner helper functions.
13900 Type clashes now generate warnings, not errors, since it
13901 appears that POSIX may allow some grammars with type clashes.
13902 * src/reader.c (grammar_current_rule_check): Warn about
13903 type clashes instead of complaining.
13904 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13906 Add Yacc library, since POSIX requires it.
13907 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13908 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13909 * lib/main.c, lib/yyerror.c: New files.
13911 gram_error can be static; it need not be extern.
13912 * src/reader.h (gram_error): Remove decl.
13913 * src/parse-gram.y (gram_error): Now static. Add static decl.
13914 (print_token_value): Omit parameter names from forward decl,
13917 2002-11-29 Paul Eggert <eggert@twinsun.com>
13919 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13920 be declared before being used. E.g., one should typically
13921 declare them in the prologue. Use GNU coding style in examples.
13922 Put "const" consistently after the type it modifies. Mention
13923 that C99 supports "inline". Mention that yyerror traditionally
13926 %parse-param and %lex-param now take just one argument, the
13927 declaration; the argument name is deduced from the declaration.
13929 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13930 Reporting, Table of Symbols): Document this.
13931 * src/parse-gram.y (add_param): New function.
13933 (declaration): Implement new rule for %parse-param and %lex-param.
13934 * src/scan-gram.l: "," now elicits a warning, rather than being
13935 a token; this is more compatible with byacc.
13936 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13938 2002-11-27 Paul Eggert <eggert@twinsun.com>
13940 Rename identifiers to avoid real and potential collisions.
13942 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13943 to avoid collision with lex macro described by Bruce Lilly in
13944 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13945 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13946 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13947 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13949 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13950 The name "yycontrol" violates the name space rules, and this stuff
13951 wasn't being used anyway.
13952 (input): Remove action; this stuff wasn't being used.
13953 (gram_error): Rename local variable yylloc -> loc.
13954 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13955 (YY_DECL): Don't use "yy" at start of local variables.
13956 All uses changed, e.g., yylloc -> loc.

13969 * tests/actions.at (Actions after errors): Use an output format
13970 more similar to that of the Printers and Destructors test.
13971 Test the position of the ';' token too.
13972 (Printers and Destructors): Likewise.
13973 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13974 unnecessarily alarming people when the test fails.
13976 * data/yacc.c (yyerrlab1): Move this label down, so that the
13977 parser does not discard the lookahead token if the user code
13978 invokes YYERROR. This change is required for POSIX conformance.
13980 * lib/error.c: Sync with gnulib.
13982 2002-11-22 Paul Eggert <eggert@twinsun.com>
13984 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.

13988 2002-11-20 Paul Eggert <eggert@twinsun.com>
13990 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13992 2002-11-20 Paul Eggert <eggert@twinsun.com>
13994 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13995 should use `if (! x) abort ();' rather than `assert (x);', and
13996 anyway it's one less thing to worry about configuring.
13998 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13999 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
14000 and replace all instances of assert with abort.
14001 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
14002 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
14004 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
14005 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
14006 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
14007 hash_find_entry, hash_rehash, hash_insert): Likewise.
14008 * src/conflicts.c (resolve_sr_conflict): Likewise.

14016 symbol_pack): Likewise.
14017 * src/tables.c (conflict_row, pack_vector): Likewise.
14018 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
14019 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
14020 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
14021 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
14023 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
14024 (ARGMATCH_CONSTRAINT): New macro.
14025 (ARGMATCH_ASSERT): Use it.
14027 * src/system.h (verify): New macro.
14028 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
14029 rather than assert.
14030 * src/tables.c (tables_generate): Likewise.
14032 * src/struniq.c (struniq_assert): Now returns void, and aborts
14033 if the assertion is false.
14034 (struniq_assert_p): Remove.
14035 * src/struniq.h: Likewise.
14037 2002-11-18 Paul Eggert <eggert@twinsun.com>
14039 * data/glr.c (yygetLRActions): Replace `yyindex' with
14040 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
14041 This fixes the regression with Sun ONE Studio 7 cc that I reported in
14042 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
14044 2002-11-18 Akim Demaille <akim@epita.fr>
14046 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
14048 From Tim Van Holder.
14050 2002-11-17 Paul Eggert <eggert@twinsun.com>
14052 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
14053 to "SyntaxError" for consistency with my 2002-11-15 change.
14055 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
14056 not define to {}, since this breaks the common use of `YYDPRINTF
14057 ((...));' if a single statement is desired (e.g. before `else').
14058 Work around GCC warnings by surrounding corresponding calls with
14060 (yyhasResolvedValue): Remove unused function.
14061 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
14063 (yyreportSyntaxError): Renamed from yyreportParseError.
14064 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
14066 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
14067 extern when possible. Remove unused initializations.
14069 2002-11-16 Akim Demaille <akim@epita.fr>
14071 Augment the similarity between GLR and LALR traces.
14073 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
14074 (YY_REDUCE_PRINT): New.
14075 (yyparse): Use them.
14076 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
14078 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
14079 state reached after the reduction/recovery, since...
14080 (yyparse, yyprocessOneStack): Report the state we are entering in.
14082 2002-11-16 Akim Demaille <akim@epita.fr>
14084 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
14085 Add support for --trace=skeleton.
14086 * src/scan-skel.l: %option debug.
14087 Scan strings of non-@ or \n instead of character by character.
14088 (scan_skel): Handle trace_skeleton.
14090 (@output_parser_name@, @output_header_name@): ``Restore'' their
14091 support (used to be M4 macros).
14092 * data/yacc.c: Quote larger chunks, a la glr.c.
14093 * data/lalr1.cc: Likewise.
14094 The header guards are no longer available, so use some other
14095 string than `YYLSP_NEEDED'.
14097 2002-11-16 Akim Demaille <akim@epita.fr>
14099 Make the ``Printers and Destructors'' test more verbose, taking
14100 `yacc.c''s behavior as (possibly wrong) reference.
14102 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
14103 instead of fprint on stdout.
14104 Set and report the last_line of the symbols.
14105 Consistently display values and locations.
14107 2002-11-16 Paul Eggert <eggert@twinsun.com>
14109 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
14111 2002-11-15 Paul Eggert <eggert@twinsun.com>
14113 * tests/actions.at (Actions after errors): New test case.
14115 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
14116 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
14117 tests/action.at, tests/calc.at, tests/conflicts.at,
14118 tests/cxx-type.at, tests/regression.at:
14119 "parse error" -> "syntax error" for POSIX compatibility.
14120 "parsing stack overflow..." -> "parser stack overflow" so
14121 that code matches Bison documentation.
14123 2002-11-15 Akim Demaille <akim@epita.fr>
14125 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
14126 take two BRACED_CODE, not two string_content.
14127 Free the scanner's obstack when we are done.
14128 (code_content): New.
14129 * tests/calc.at: Adjust.
14130 * doc/bison.texinfo: Adjust.
14131 Also, make sure to include the `,' for these declarations.
14133 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
14135 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
14136 definition; avoids potential autoreconf problems.
14138 2002-11-15 Akim Demaille <akim@epita.fr>
14140 Always check the value returned by yyparse.
14142 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
14143 returned by yyparse.

14154 2002-11-14 Paul Eggert <eggert@twinsun.com>
14156 * src/output.c (output_skeleton): Call xfopen instead of
14157 duplicating xfopen's body.
14159 Fix bugs reported by Nelson H. F. Beebe in
14160 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
14162 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
14163 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
14164 Group compiler. Instead, use "$CC -E bar.c". Include the .h
14165 file twice in the grammar, as an extra check.
14167 * tests/input.at (Torturing the Scanner): Surround the
14168 backslash-newline tests with "#if 0", to make it less likely that
14169 we'll run into compiler bugs. Bring back solitary \ inside
14170 comment, but add a closing comment to work around HP C bug. Don't
14171 test backslash-newline in C character constant.
14173 2002-11-14 Akim Demaille <akim@epita.fr>
14175 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
14176 status of the compiler.
14177 Calling `exit 1' is no longer needed.
14178 Reported by Nelson H. F. Beebe.

14186 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
14187 * tests/regression.at, tests/torture.at: Use them for all the
14188 grammars that are to be compiled.
14189 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
14190 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
14191 * doc/bison.texinfo (GLR Parsers): Document `inline'.
14193 2002-11-14 Akim Demaille <akim@epita.fr>
14195 * doc/bison.texinfo: Various formatting changes (alignments in
14196 samples, additional @group/@end group, GCS in samples.
14197 Use @deffn instead of simple @table to define the directives,
14198 macros, variables etc.
14200 2002-11-13 Paul Eggert <eggert@twinsun.com>
14202 Fix some bugs reported by Albert Chin-A-Young in
14203 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
14205 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
14206 -o c"; the HP C compiler chatters during compilation.
14207 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
14208 * tests/headers.at (export YYLTYPE): Likewise.
14210 * tests/input.at (Torturing the Scanner): Remove lines containing
14211 solitary backslashes, as they tickle a bug in the HP C compiler.
14213 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
14214 comments, since they're not portable. Use GNU coding style.
14216 2002-11-13 Akim Demaille <akim@epita.fr>
14218 * data/yacc.c: Leave bigger chunks of quoted text.
14219 (YYDSYMPRINTF): New.
14220 Use it to report symbol activities.

14228 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
14229 (yyglrReduce): Return yyok, not 0.
14230 This should avoid the enumerated-type warnings reported
14231 by Nelson H. F. Beebe in
14232 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.

14235 * lib/bitset.h [! BITSET_INLINE]: Remove.
14236 (bitset_set, bitset_reset, bitset_test): Rename local vars
14237 to avoid shadowing warnings by GCC.
14239 * data/glr.c (inline): Remove #define. It's the user's
14240 responsibility to #define it away, just like 'const'.
14241 This fixes one of the bugs reported by Nelson H. F. Beebe in
14242 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
14244 * Makefile.maint (po-check): Scan .l and .y files instead of the
14245 .c and the .h files that they generate. This fixes the bug
14246 reported by Tim Van Holder in:
14247 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
14248 Look for N_ as well as for _. Try to avoid matching #define for

14253 do not confuse xgettext.
14255 * src/struniq.h (struniq_new): Do not declare the return type
14256 to be 'const'; this violates the C standard.
14257 * src/struniq.c (struniq_new): Likewise.
14259 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
14261 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

14267 * Makefile.maint: Sync with Autoconf:

14293 * data/glr.c (yystos): New.
14294 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
14295 (YYDSYMPRINT): New.
14296 (yyval): Don't define it, it is handled via M4.

14310 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
14311 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
14312 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
14313 it against YYEMPTY and so forth), work on yytoken (i.e., set
14314 it to YYEMPTY etc.).
14315 (yydestruct): Replace with a b4_yydestruct_generate invocation.
14316 (b4_symbol_actions): Remove.
14317 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
14318 for 0, end-of-input.

14324 2002-11-12 Akim Demaille <akim@epita.fr>
14326 * src/tables.c (tables_generate): Use free for pointers that
14327 cannot be NULL, not XFREE.

14393 type_name are properly removed.
14394 Don't use XFREE to free items that cannot be NULL.
14395 * src/struniq.h, src/struniq.c: New.
14396 * src/main.c (main): Initialize/free struniqs.
14397 * src/parse-gram.y (%union): Add astruniq member.
14399 * src/scan-gram.l (<{tag}>): Return a struniq.
14400 Free the obstack bit that used to store it.
14401 * src/symtab.h (symbol_t): The 'type_name' member is a struniq.
14403 2002-11-11 Paul Eggert <eggert@twinsun.com>
14405 Revamp to fix many (but not all) of the C- and M4-related quoting
14406 problems. Among other things, this fixes the Bison bug reported
14407 by Jan Hubicka when processing the Bash grammar; see:
14408 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
14410 Use new @ escapes consistently. Represent brackets with @{ and @}
14411 rather than @<:@ and @:>@, since this works a bit better with dumb
14412 editors like vi. Represent @ with @@, since @ is now consistently
14413 an escape. Use @oline@ and @ofile@ rather than __oline__ and
14414 __ofile__, to avoid unexpected expansions. Similarly, use @output
14415 rather than #output.
14417 * data/c.m4 (b4_copyright): Omit file name from comment, since
14418 the file name could contain "*/".
14419 (b4_synclines_flag): Don't quote the 2nd argument; it should already
14420 be quoted. All uses changed.
14422 * data/glr.c: Use new @ escapes consistently.
14423 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
14424 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
14425 Remove, since they couldn't handle arbitrary characters in file
14427 * data/lalr1.cc: Likewise.
14428 * data/yacc.c: Likewise.
14430 * src/files.c (output_infix): Remove; all uses removed.
14431 * src/files.h: Likewise.
14433 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
14434 mishandled funny characters in file names, and anyway it isn't
14436 * data/yacc.c: Likewise.
14437 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
14439 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
14440 * data/yacc.c: Likewise.
14442 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
14444 (muscle_init): Quote filename as a C string.
14445 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
14446 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
14447 * src/output.c (escaped_file_name_output): New function.
14448 (prepare_symbols): Quote tokens for M4.
14449 (prepare): Don't insert output_infix, output_prefix,
14450 output_parser_name, output_header_name; this is now down by scan-skel.
14451 Insert skeleton as a C string.
14453 * src/output.c (user_actions_output, symbol_destructors_output,
14454 symbol_printers_output): Quote filenames for C and M4.
14455 * src/reader.c (prologue_augment, epilogue_set): Likewise.
14457 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
14458 escapes other than \\ and \'; this simplifies the code.
14459 (<SC_STRING>): Likewise, for \\ and \".
14460 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
14461 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
14462 Use new escapes @{ and @} for [ and ].
14464 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
14465 them with auto vars.
14466 Switch to new escape scheme, where @ is the escape character uniformly.
14467 Abort if a stray escape character is found. Avoid unbounded input
14468 buffer when parsing non-escaped text.
14470 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
14471 __oline__, #output, $@, and @{ do not have unintended meanings.
14473 2002-11-09 Paul Eggert <eggert@twinsun.com>
14475 Fix the test failure due to GCC warnings described in
14476 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
14477 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
14478 evaluate to 0 if it's impossible for NINF to be in the respective
14480 (yygetLRActions, yyrecoverParseError): Use them.
14482 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
14483 counted in the token inserted at end of file. Now takes
14484 location_t *, not location_t, so that the location can be
14485 adjusted. All uses changed.
14487 * tests/regression.at (Invalid inputs): Adjust wording in
14488 diagnostic to match the new behavior.
14490 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
14491 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
14492 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
14493 abort ();'. This reduces the runtime of the "Many lookaheads"
14494 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
14497 2002-11-07 Paul Eggert <eggert@twinsun.com>
14499 * src/parse-gram.y (CHARACTER): Remove unused token.
14502 * src/scan-gram.l: Remove stack option. We no longer use the
14503 stack, since the stack was never deeper than 1; instead, use the
14504 new auto var c_context to record the stacked value.
14506 Remove nounput option. At an unexpected end of file, we now unput
14507 the minimal input necessary to end cleanly; this simplifies the
14510 Avoid unbounded token sizes where this is easy.
14512 (unexpected_end_of_file): New function.
14513 Use it to systematize the error message on unexpected EOF.
14514 (last-string): Now auto, not static.
14515 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
14516 (scanner_last_string_free): Remove; not used.
14517 (percent_percent_count): Move decl to just before use.
14518 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
14519 not the (never otherwised-used) CHARACTER.
14521 2002-11-07 Akim Demaille <akim@epita.fr>
14523 Let yyerror always receive the msg as last argument, so that
14524 yyerror can be variadic.
14526 * data/yacc.c (b4_yyerror_args): New.
14527 Use it when calling yyerror.
14528 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
14529 Use it when calling yyerror.

14532 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
14534 2002-11-06 Akim Demaille <akim@epita.fr>
14536 #line should have quoted strings.
14537 Ideally, this should be done by m4_quotearg.
14539 * src/scan-skel.l: Include quotearg.h.
14541 * src/output.c (symbol_printers_output)
14542 (symbol_destructors_output): Quote the file name.
14544 2002-11-06 Akim Demaille <akim@epita.fr>

14555 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
14556 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
14557 * src/output.c (user_actions_output): Likewise.
14558 (prepare): Define 'b4_synclines_flag'.
14559 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
14561 2002-11-06 Akim Demaille <akim@epita.fr>

14564 * src/scan-gram.l (handle_syncline): New.
14566 * src/output.c (user_actions_output, symbol_destructors_output)
14567 (symbol_printers_output): Use the location's file name, not
14569 * src/reader.c (prologue_augment, epilogue_set): Likewise.
14571 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14573 * src/tables.c (matching_state): Don't allow states to match if
14574 either has GLR conflict entries.
14576 2002-11-05 Paul Eggert <eggert@twinsun.com>
14578 * src/scan-gram.l: Use more accurate diagnostics, e.g.
14579 "integer out of range" rather than "invalid value".
14580 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
14583 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
14584 Also, remove one static variable in the scanner.
14586 * src/scan-gram.l (braces_level): Now auto, not static.
14587 Initialize to zero if the compiler is being picky.
14588 (INITIAL): Clear braces_level instead of incrementing it.
14589 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
14590 as POSIX 1003.1-2001 requires.
14591 * src/system.h (IF_LINT): New macro, taken from coreutils.
14592 * configure.ac: Define "lint" if --enable-gcc-warnings.
14594 2002-11-05 Akim Demaille <akim@epita.fr>
14596 * src/scan-gram.l: When it starts with `%', complain about the
14597 whole directive, not just that `invalid character: %'.
14599 2002-11-04 Akim Demaille <akim@epita.fr>
14601 * Makefile.maint: Update from Autoconf.
14602 (update, cvs-update, po-update, do-po-update): New.
14604 2002-11-04 Akim Demaille <akim@epita.fr>
14606 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
14608 Have yyerror `use' its arguments.
14609 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
14610 returns true when location & yacc & pure & parse-param.
14611 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
14613 2002-11-04 Akim Demaille <akim@epita.fr>
14615 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
14617 * src/scan-gram.l: Use [\'] instead of ['] to pacify
14620 Use quote, not quote_n since LOCATION_PRINT no longer uses the
14623 2002-11-03 Paul Eggert <eggert@twinsun.com>
14625 * src/reader.c (get_merge_function, grammar_current_rule_check):
14626 Use consistent diagnostics for reporting type name clashes.
14627 Quote the types with <>, for consistency with Yacc.
14628 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
14630 2002-11-03 Akim Demaille <akim@epita.fr>
14632 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
14634 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
14635 (b4_parse_param): Remove.
14636 Use b4_identification.
14637 Propagate b4_pure_args where needed to pass them to yyerror.
14638 * data/glr.m4 (b4_parse_param): Remove.
14639 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

14641 Use b4_identification.
14642 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
14643 b4_user_formals and b4_user_args.
14644 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
14645 (yyreportAmbiguity): When using a pure parser, also need
14646 the location, and the parse-params.
14648 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
14649 When using a pure parser, also need the parse-params.
14651 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
14652 (%pure-parser + %parse-param) LALR and GLR parsers.
14653 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
14654 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
14655 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
14656 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
14657 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
14658 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
14659 * doc/bison.texinfo: Untabify the whole file.
14660 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
14661 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
14662 (Error Reporting): Adjust to these new directives.
14663 Document %error-verbose, deprecate YYERROR_VERBOSE.
14665 2002-11-03 Akim Demaille <akim@epita.fr>
14667 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
14668 AT_CHECK_CALC_GLR invocations to use % directives, instead of
14669 command line options.
14670 * tests/cxx-type.at: Formatting changes.
14672 2002-11-03 Paul Eggert <eggert@twinsun.com>
14674 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
14675 to count columns correctly, and to check for invalid inputs.
14677 Use mbsnwidth to count columns correctly. Account for tabs, too.
14678 Include mbswidth.h.
14679 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
14680 (extend_location): New function.
14681 (YY_LINES): Remove.
14683 Handle CRLF in C code rather than in Lex code.
14684 (YY_INPUT): New macro.
14685 (no_cr_read): New function.
14687 Scan UCNs, even though we don't fully handle them yet.
14688 (convert_ucn_to_byte): New function.
14690 Handle backslash-newline correctly in C code.
14691 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
14692 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
14694 (tag, splice): New EREs. Do not allow NUL or newline in tags.
14695 Use {splice} wherever C allows backslash-newline.
14696 YY_STEP after space, newline, vertical-tab.
14697 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
14699 (letter, id): Don't assume ASCII; e.g., spell out a-z.
14701 ({int}, handle_action_dollar, handle_action_at): Check for integer
14704 (YY_STEP): Omit trailing semicolon, so that it's more like C.
14706 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
14707 as well as \000. Check for UCHAR_MAX, not 255.
14708 Allow \x with an arbitrary positive number of digits, as in C.
14709 Check for overflow here.
14710 Allow \? and UCNs, for compatibility with C.
14712 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
14713 with quote slot used by complain_at.
14715 * tests/input.at: Add tests for backslash-newline, m4 quotes
14716 in symbols, long literals, and funny escapes in strings.
14718 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
14719 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
14720 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
14721 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
14722 * m4/mbswidth.m4: New file, from GNU coreutils.
14724 * doc/bison.texinfo (Grammar Outline): Document // comments.
14725 (Symbols): Document that trigraphs have no special meaning in Bison,
14726 nor is backslash-newline allowed.
14727 (Actions): Document that trigraphs have no special meaning.
14729 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
14732 2002-11-02 Paul Eggert <eggert@twinsun.com>
14734 * src/reader.c: Don't include quote.h; not needed.
14735 (get_merge_function): Reword warning to be consistent with
14736 type clash diagnostic in grammar_current_rule_check.
14738 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
14739 bug in trigraph handling.
14741 * src/output.c (prepare_symbols): When printing token names,
14742 escape "[" as "@<:@" and likewise for "]".
14744 * src/system.h (errno): Remove declaration, as we are now
14745 assuming C89 or better, and C89 guarantees errno.
14747 2002-10-30 Paul Eggert <eggert@twinsun.com>
14749 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
14750 Check for close failures.
14751 * src/files.h (xfclose): Return void, not int, since it always
14753 * src/files.c (xfclose): Likewise. Report I/O error if ferror
14755 * src/output.c (output_skeleton): Use xfclose rather than fclose
14756 and ferror. xfclose now checks ferror.
14758 * data/glr.c (YYLEFTMOST_STATE): Remove.
14759 (yyreportTree): Use a stack-based leftmost state. This avoids
14760 our continuing battles with bogus warnings about initializers.
14762 2002-10-30 Akim Demaille <akim@epita.fr>
14764 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
14767 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14769 * tests/glr-regr1.at: New test for reported regressions.
14770 * tests/testsuite.at: Add glr-regr1.at test.
14771 * tests/Makefile.am: Add glr-regr1.at test.
14773 2002-10-24 Paul Eggert <eggert@twinsun.com>
14777 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
14778 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
14779 we use malloc. Don't assume 'A' through 'Z' are contiguous.
14780 Don't assume strdup exists; POSIX says its an XSI extension.
14781 Check for buffer overflow on input.
14783 2002-10-24 Akim Demaille <akim@epita.fr>
14785 * src/output.c (output_skeleton): Don't disable M4sugar comments
14786 too soon: it results in comments being expanded.
14787 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
14790 2002-10-24 Akim Demaille <akim@epita.fr>
14792 * data/yacc.c (m4_int_type): New.
14793 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
14794 char' as only yacc.c wants K&R portability.
14795 * data/glr.c (yysigned_char): Remove.
14796 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
14797 Reported by Quoc Peyrot.
14799 2002-10-23 Paul Eggert <eggert@twinsun.com>
14801 * src/main.c (main): With --trace=time, report times even if a
14802 non-fatal error occurs. Formerly, the times were reported in some
14803 such cases but not in others.
14804 * src/reader.c (reader): Just return if a complaint has been issued,
14805 instead of exiting, so that 'main' can report times.
14807 2002-10-22 Akim Demaille <akim@epita.fr>
14809 * src/system.h: Include sys/types.
14810 Reported by Bert Deknuydt.
14812 2002-10-23 Paul Eggert <eggert@twinsun.com>
14814 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
14815 Suggested by Art Haas.
14817 2002-10-22 Paul Eggert <eggert@twinsun.com>
14819 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14820 decl; not needed any more.
14821 * src/main.c (main): Use return to exit, undoing yesterday's change.
14822 The last OS that we could find where this wouldn't work is
14823 SunOS 3.5, and that's too old to worry about now.
14825 * data/glr.c (struct yyltype): Define members even when not
14826 doing locations. This is more consistent with yacc.c, and it
14827 works around the following bug reports:
14828 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
14829 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
14831 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
14832 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14833 "Algol" instead of "ALGOL". Give a bit more history about BNF.
14835 2002-10-22 Akim Demaille <akim@epita.fr>
14837 * data/README: New.
14839 2002-10-21 Paul Eggert <eggert@twinsun.com>
14841 Be consistent about 'bool'; the old code used an enum in one
14842 module and an int in another, and this violates the C standard.
14843 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14844 * configure.ac (AC_HEADER_STDBOOL): Add.
14845 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14846 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14847 * src/symtab.c (hash_compare_symbol_t): Likewise.
14848 * src/system.h (bool, false, true): Use a definition consistent
14849 with ../lib/hash.c. All uses changed.
14851 * src/complain.c (warning_issued): Renamed from warn_message_count,
14852 so that we needn't worry about integer overflow (!).
14853 Now of type bool. All uses changed.
14854 (complaint_issued): Renamed from complain_message_count; likewise.
14856 * src/main.c (main): Use exit to exit with failure.
14858 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
14859 rather than 1 and 0.

14865 "Try `bison --help'".
14867 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
14868 What was that "2" for?
14870 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14871 * src/getargs.c (usage): Likewise.
14873 * src/getargs.c (getargs): When there are too few operands, report
14874 the last one. When there are too many, report the first extra
14875 one. This is how diffutils does it.
14877 2002-10-20 Paul Eggert <eggert@twinsun.com>
14879 Remove K&R vestiges.
14880 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.

14884 fatal): Assume prototypes.
14885 * src/complain.h: Assume prototypes.
14886 * src/system.h (PARAMS): Remove.
14887 Include <limits.h> unconditionally, since it's guaranteeed even
14888 for a freestanding C89 compiler.
14889 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
14890 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.

14904 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14905 arguments and output `void'.
14906 (b4_c_function): Rename as...
14907 (b4_c_function_def): this.
14908 (b4_c_function_decl, b4_c_ansi_function_def)

14951 2002-10-19 Paul Eggert <eggert@twinsun.com>
14953 Do not create a temporary file, as that involves security and
14954 cleanup headaches. Instead, use a pair of pipes.
14955 Derived from a suggestion by Florian Krohm.
14956 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14957 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
14958 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
14959 (BISON_PREREQ_SUBPIPE): Add.
14960 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
14961 Add subpipe.h, subpipe.c.

14970 * src/scan-skel.l (readpipe): Remove decl.
14971 (scan_skel): New function, to be used in place of m4_invoke.
14972 Read from stream rather than file.
14974 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14975 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14976 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14977 this generates a more-accurate value anyway.
14979 * lib/timevar.c (timervar_accumulate): Rename locals to
14980 avoid confusion with similarly-named more-global.
14981 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14983 * src/output.c (prepare): Use xstrdup to convert char const *
14984 to char *, to avoid GCC warning.
14986 2002-10-19 Akim Demaille <akim@epita.fr>
14988 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14989 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14990 Use them to have `calc.y' ready for %pure-parser.
14991 * data/yacc.c (YYLEX): Pass a yylex return type to
14992 b4_c_function_call.
14994 2002-10-19 Akim Demaille <akim@epita.fr>
14996 Prototype support of %lex-param and %parse-param.
14998 * src/parse-gram.y: Add the definition of the %lex-param and
14999 %parse-param tokens, plus their rules.
15000 Drop the `_' version of %glr-parser.
15002 * src/scan-gram.l (INITIAL): Scan them.
15003 * src/muscle_tab.c: Comment changes.

15006 (muscle_entry_s): The `value' member is no longer const.
15007 Adjust all dependencies.
15008 * src/muscle_tab.c (muscle_init): Adjust: use
15009 MUSCLE_INSERT_STRING.
15010 Initialize the obstack earlier.

15012 (muscle_pair_list_grow): New.
15013 * data/c.m4 (b4_c_function_call, b4_c_args): New.
15014 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
15015 * tests/calc.at: Use %locations, not --locations.
15016 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
15018 2002-10-19 Akim Demaille <akim@epita.fr>
15020 * src/getargs.c (usage): Take status as argument and exit
15022 Report the traditional `Try ... --help' message when status != 0.
15023 (usage, version): Don't take a FILE * as arg, it is pointless.
15024 (getargs): When there is an incorrect number of arguments, make it
15025 an error, and report it GNUlically thanks to `usage ()'.
15027 2002-10-18 Paul Eggert <eggert@twinsun.com>
15029 * data/glr.c (yyreportParseError): Don't assume that sprintf
15030 yields the length of the printed string, as this is not true
15031 on SunOS 4.1.4. Reported by Peter Klein.
15033 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
15034 * tests/conflicts.at (%nonassoc and eof): Likewise.
15035 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
15037 2002-10-17 Akim Demaille <akim@epita.fr>
15039 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
15040 * src/getargs.c (trace_types, trace_args): Adjust.
15041 * src/reader.c (grammar_current_rule_prec_set)
15042 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
15043 Standardize error messages.
15044 And s/@prec/%prec/!
15045 (reader): Use trace_flag to enable scanner/parser debugging,
15046 instead of an adhoc scheme.
15047 * src/scan-gram.l: Remove trailing debugging code.
15049 2002-10-16 Paul Eggert <eggert@twinsun.com>
15051 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
15054 * NEWS: Officially drop support for building Bison with K&R C,
15055 since it didn't work anyway and it's not worth worrying about.
15056 * Makefile.maint (wget_files): Remove ansi2knr.c.
15057 (ansi2knr.c-url_prefix): Remove.
15058 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
15059 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15060 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15062 2002-10-15 Paul Eggert <eggert@twinsun.com>
15064 Stop using the "enum_" trick for K&R-style function definitions;
15065 it confused me, and I was the author! Instead, assume that people
15066 who want to use K&R C compilers (when using these modules in GCC,
15067 perhaps?) will run ansi2knr.
15069 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
15070 All uses of "enum_" changed to "enum ".
15071 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15072 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15074 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

15082 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
15083 Use function prototypes; this removes the need for declaring
15084 static functions simply to provide their prototypes.
15085 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

15151 2002-10-14 Akim Demaille <akim@epita.fr>
15153 * src/tables.c (table_ninf_remap): base -> tab.
15154 Reported by Matt Rosing.
15156 2002-10-14 Paul Eggert <eggert@twinsun.com>

15159 tests/cxx-type.at, tests/headers.at, tests/input.at,
15160 tests/regression.at, tests/synclines.at, tests/torture.at:
15161 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
15162 so that the tests still work even if POSIXLY_CORRECT is set.
15163 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
15165 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
15166 for portability to K&R hosts. Fix typo: signed char is guaranteed
15167 only to 127, not to 128.
15168 * data/glr.c (yysigned_char): New type.
15169 * data/yacc.c (yysigned_char): Likewise.
15170 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
15172 2002-10-13 Paul Eggert <eggert@twinsun.com>
15174 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
15175 true due to limited range of data type" warning from GCC.
15177 * data/c.m4 (b4_token_defines): Protect against double-inclusion
15178 by wrapping enum yytokentype's definition inside #ifndef
15179 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
15181 2002-10-13 Akim Demaille <akim@epita.fr>
15183 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
15184 Un yy- yyrhs to avoid the name clash with the global YYRHS.
15186 2002-10-13 Akim Demaille <akim@epita.fr>
15188 * Makefile.maint: Update from Autoconf 2.54.
15189 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
15191 2002-10-13 Akim Demaille <akim@epita.fr>
15193 * src/print.c (print_state): Separate the list of solved conflicts
15194 from the other items.
15195 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
15197 2002-10-13 Akim Demaille <akim@epita.fr>
15199 Let nondeterministic skeletons be usable with deterministic
15202 With the patch, GAWK compiled by GCC without -O2 passes its test
15203 suite using a GLR parser driven by LALR tables. It fails with -O2
15204 because `struct stat' gives two different answers on my machine:
15205 88 (definition of an auto var) and later 96 (memset on this var).
15206 Hence the stack is badly corrumpted. The headers inclusion is to
15207 blame: if I move the awk.h inclusion before GLR's system header
15208 inclusion, the two struct stat have the same size.
15210 * src/tables.c (pack_table): Always create conflict_table.
15211 (token_actions): Always create conflict_list.
15212 * data/glr.c (YYFLAG): Remove, unused.
15214 2002-10-13 Akim Demaille <akim@epita.fr>
15216 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
15218 (VALGRIND, GXX): New.
15219 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
15220 * tests/bison.in: Run $PREBISON a pre-command.
15221 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
15222 (maintainer-check-g++): New.
15223 * Makefile.am (maintainer-check): New.
15225 2002-10-13 Akim Demaille <akim@epita.fr>
15227 * data/glr.c: Formatting changes.
15228 Tweak some trace messages to match yacc.c's.
15230 2002-10-13 Akim Demaille <akim@epita.fr>
15232 GLR parsers sometimes raise parse errors instead of performing the
15234 Reported by Charles-Henry de Boysson.
15236 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
15237 check the length of the traces when %glr.
15238 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
15240 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
15242 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
15243 (yyltype): Remove the yy prefix from the member names.
15244 (yytable): Complete its comment.
15245 (yygetLRActions): Map error action number from YYTABLE from
15247 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
15248 (which was a bug: it should have been YYTABEL_NINF, and yet it was
15249 not satisfying as we could compare an YYACTION computed from
15250 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
15251 only value for error actions.
15252 (yyreportParseError): In verbose parse error messages, don't issue
15253 `error' in the list of expected tokens.
15254 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
15255 next action to perform to match glr.c's decoding.
15256 (yytable): Complete its comment.
15258 2002-10-13 Paul Eggert <eggert@twinsun.com>
15260 Fix problem reported by Henrik Grubbstroem in
15261 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
15262 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
15263 because the Bison parser reads the second action before reducing
15265 * src/scan-gram.l (rule_length): New static var.
15266 Use it to keep track of the rule length in the scanner, since
15267 we can't expect the parser to be in lock-step sync with the scanner.
15268 (handle_action_dollar, handle_action_at): Use this var.
15269 * tests/actions.at (Exotic Dollars): Test for the problem.
15271 2002-10-12 Paul Eggert <eggert@twinsun.com>
15273 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.

15281 (get_time) [IN_GCC]: Keep the GCC version for reference.
15283 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
15284 GCC version as of today, then merge Bison's changes.
15285 Change "GCC" to "Bison" in copyright notice. timevar.def's
15286 author is Akim, so change that too.
15288 * src/reader.c (grammar_current_rule_check):
15289 Don't worry about the default action if $$ is untyped.
15290 Prevents bogus warnings reported by Jim Gifford in

15301 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
15302 (yyparse): here. This undoes some of the 2002-07-25 change.
15303 Compatibility problem reported by Ralf S. Engelschall with

15322 * lib/abitset.c: Include <stddef.h>, for offsetof.
15323 * lib/lbitset.c: Likewise.
15325 * lib/abitset.c (abitset_bytes): Return a size that is aligned
15326 properly for vectors of objects. Do not assume that adding a
15327 header size to a multiple of a word size yields a value that is
15328 properly aligned for the whole union.
15329 * lib/bitsetv.c (bitsetv_alloc): Likewise.
15331 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
15332 unique names for structures.

15342 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
15343 to improve the type-checking that GCC can do.

15345 * lib/bitset_stats.c (bitset_stats_count,
15346 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

15364 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
15365 All instances of parameters of type enum bitset_opts are now of
15366 type enum_bitset_opts, to conform to the C Standard, and similarly
15367 for enum_bitset_type.
15368 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15369 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15371 Do not use "struct bitset_struct" to mean different things in
15372 different modules. Not only is this confusing, it violates
15373 the C Standard, which requires that structure types in different
15374 modules must be compatible if one is to be passed to the other.
15375 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
15376 All instances of "struct bitset_struct *" replaced with "bitset".
15377 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
15378 (union bitset_union, struct abitset_struct, struct ebitset_struct,

15387 bitset_struct): Remove.
15388 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
15391 Do not call a function of type T using a call that assumes the
15392 function is of a different type U. Standard C requires that a
15393 function must be called with a type that is compatible with its

15397 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
15399 * lib/ebitset.c (PFV): Remove.

15416 Use offsetof, for simplicity.
15418 2002-10-06 Paul Eggert <eggert@twinsun.com>
15420 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
15421 the same width as int. This reapplies a hunk of the 2002-08-12 patch
15422 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
15423 which was inadvertently undone by the 2002-09-30 patch.
15424 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
15425 the same width as int.
15427 2002-10-04 Paul Eggert <eggert@twinsun.com>
15431 * configure.ac (AC_INIT), NEWS: Increment version number.
15433 * doc/bison.texinfo: Minor spelling, grammar, and white space
15435 (Symbols): Mention that any negative value returned from yylex
15436 signifies end-of-input. Warn about negative chars. Mention
15437 the portable Standard C character set.

15440 for the installer to set.
15441 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
15442 * src/Makefile.am (AM_CFLAGS): Likewise.

15452 POSIX 1003.1-2001 has removed fgrep.
15454 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

15971 parsers now contain `reduce 0' as default reduction.

16022 token_translations instead of `0'.
16023 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
16025 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
16026 for the time being: %locations ought to provide it to yyerror.
16028 2002-07-25 Akim Demaille <akim@epita.fr>
16030 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

16045 Handle the `- 1' part in rule numbers from/to item numbers.

17646 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
17647 constructors or destructors.
17649 (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.

17676 * tests/regression.at (Web2c Actions): Adjust.
17678 2002-04-22 Akim Demaille <akim@epita.fr>
17680 * src/reader.c (token_translations_init): 256 is now the default
17681 value for the error token, i.e., it will be assigned another

17683 (reader): Don't force 256 to error.
17684 * doc/bison.texinfo (Symbols): Adjust.

17686 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
17687 etc. instead of 10, 20, 30 (which was used to `jump' over error
17688 (256) and undefined (2)).

17727 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
17728 full stderr, and strip it according to the bison options, instead

17731 Adjust all the invocations.
17732 Add an invocation exercising the error token.
17733 Add an invocation demonstrating a stupid error message.
17734 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

17746 (state_t.number): Is a token_number_t.

17752 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
17753 `user_token_number_max'.

17794 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
17795 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
17796 passes, but produces negative #line number, once fixed, GCC is

17997 2002-04-07 Akim Demaille <akim@epita.fr>
17999 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
18000 lacking `+ 1' to nrules, Bison reported as useless a token if it
18001 was used solely to set the precedence of the last rule...
18003 2002-04-07 Akim Demaille <akim@epita.fr>
18005 * data/bison.c++, data/bison.simple: Don't output the current file
18006 name in #line, to avoid useless diffs between two identical
18007 outputs under different names.
18009 2002-04-07 Akim Demaille <akim@epita.fr>
18011 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

18026 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
18027 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
18028 RHS, instead of being an index in RITEMS.
18030 2002-04-04 Paul Eggert <eggert@twinsun.com>
18032 * doc/bison.texinfo: Update copyright date.
18033 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

18299 Remove the support for C++ namespace cleanliness; it was

18387 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
18388 specific values. Now it is m4 that performs the lookup.

18397 (output_skeleton): Don't look for the skeleton location, let m4 do
18399 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
18401 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
18402 (prepare): Given that for the time being changesyntax is not
18403 usable in M4, rename the muscles using `-' to `_'.
18404 Define `defines_flag', `output_parser_name' and `output_header_name'.
18405 * src/output.h (actions_output, guards_output)
18406 (token_definitions_output): Adjust prototypes.
18407 * src/scan-skel.l: Instead of scanning the skeletons, it now

18410 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
18412 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'

18414 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
18415 shamelessly stolen from CVS Autoconf.

18433 2002-01-29 Paul Eggert <eggert@twinsun.com>
18435 * src/bison.simple (YYSIZE_T): Do not define merely because
18436 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
18437 On some platforms, <alloca.h> does not declare YYSTD (size_t).
18439 2002-01-27 Akim Demaille <akim@epita.fr>
18441 Fix `%nonassoc and eof'.
18443 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
18444 which were not properly copied! Replace
18445 memcpy (res->errs, src->errs, src->nerrs);
18447 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
18449 * tests/regression.at (%nonassoc and eof): Adjust to newest
18450 Autotest: `.' is not in the PATH.

18466 * tests/regression.at (%nonassoc and eof): New.
18467 Suggested by Robert Anisko.
18469 2002-01-24 Akim Demaille <akim@epita.fr>

18501 Reported by Evgeny Stambulchik.
18503 2002-01-20 Marc Autret <marc@gnu.org>
18505 * src/system.h: Need to define __attribute__ away for non-GCC
18506 compilers as well (i.e., the vendor C compiler).
18507 Suggested by Albert Chin-A-Young.
18509 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
18511 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
18512 canonical definition.
18513 * src/system.h: Use the canonical definition for PARAMS (avoids
18514 a conflict with the macro from lib/hash.h).
18516 2002-01-11 Akim Demaille <akim@epita.fr>

18552 2002-01-08 Akim Demaille <akim@epita.fr>

18562 * lib/hash.h (__P): Added definition for this macro.
18563 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
18564 BUILT_SOURCES, to ensure they are generated first.
18565 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
18566 %error-verbose to allow bootstrapping with bison 1.30x.
18568 2002-01-06 Akim Demaille <akim@epita.fr>
18570 * src/reader.c (parse_braces): Don't fetch the next char, the
18571 convention is to fetch on entry.
18572 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
18573 'switch' without a following semicolon.
18574 * tests/regression.at (braces parsing): New.
18576 2002-01-06 Akim Demaille <akim@epita.fr>

18581 * src/conflicts.c (count_rr_conflicts): Fix.
18583 2002-01-06 Akim Demaille <akim@epita.fr>
18585 Creating package.m4 from configure.ac causes too many problems.
18587 * tests/Makefile.am (package.m4): Create it by hand,
18588 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
18590 2002-01-06 Akim Demaille <akim@epita.fr>

18611 2002-01-03 Akim Demaille <akim@epita.fr>
18613 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
18614 The ISO C++ standard is extremely clear about it: stderr is
18615 considered a macro, not a regular symbol (see table 94 `Header
18616 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
18617 Therefore std:: does not apply to it. It still does with fprintf.
18618 Also, s/cstdio.h/cstdio/.
18620 2002-01-03 Akim Demaille <akim@epita.fr>
18622 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
18623 for non system headers.
18625 2002-01-02 Akim Demaille <akim@epita.fr>
18627 Equip the skeleton chain with location tracking, runtime trace,
18628 pure parser and scanner.
18630 * src/parse-skel.y: Request a pure parser, locations, and prefix
18632 (%union): Having several members with the same type does not help
18633 type mismatches, simplify.
18634 (YYPRINT, yyprint): New.
18635 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
18636 (skel_error): this.
18638 * src/scan-skel.l: Adjust to these changes.
18639 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
18640 (LOCATION_PRINT, skel_control_t): New.
18642 2001-12-30 Akim Demaille <akim@epita.fr>
18644 * src/parse-skel.y: Get rid of the shift/reduce conflict:
18645 replace `gb' with BLANKS.
18646 * src/scan-skel.l: Adjust.
18648 2001-12-30 Akim Demaille <akim@epita.fr>
18650 * src/system.h: We don't need nor want bcopy.
18651 Throw away MS-DOS crap: we don't need getpid.
18652 * configure.in: We don't need strndup. It was even causing
18653 problems: because Flex includes the headers *before* us,
18654 _GNU_SOURCE is not defined by config.h, and therefore strndup was
18656 * lib/xstrndup.c: New.
18657 * src/scan-skel.l: Use it.
18658 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
18659 * src/parse-skel.y: Use %directives instead of #defines.
18661 2001-12-30 Akim Demaille <akim@epita.fr>
18663 * src/skeleton.h: New.
18664 * src/output.c (output_parser, output_master_parser): Remove, dead
18666 * src/output.h (get_lines_number, actions_output, guards_output)
18667 (token_definitions_output): Prototype them.
18668 * src/parse-skel.y: Add the license notice.
18669 Include output.h and skeleton.h.
18670 (process_skeleton): Returns void, and takes a single parameter.
18671 * src/scan-skel.l: Add the license notice.
18672 Include skeleton.h.
18673 Don't use %option yylineno: it seems that then Flex imagines
18674 REJECT has been used, and therefore it won't reallocate its
18675 buffers (which makes no other sense to me than a bug). It results
18676 in warnings for `unused: yy_flex_realloc'.
18678 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
18680 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
18681 (MUSCLE_INSERT_PREFIX): ...to there.
18682 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
18683 (MUSCLE_INSERT_PREFIX): Move from here...
18685 * src/bison.hairy: Add a section directive. Put braces around muscle
18686 names. This parser skeleton is still broken, but Bison should not
18687 choke on a bad muscle 'syntax'.
18688 * src/bison.simple: Add a section directive. Put braces around muscle
18691 * src/files.h (strsuffix, stringappend): Add declarations.
18692 (tab_extension): Add declaration.
18693 (short_base_name): Add declaration.
18695 * src/files.c (strsuffix, stringappend): No longer static. These
18696 functions are used in the skeleton parser.
18697 (tab_extension): New.
18698 (compute_base_names): Use the computations done in this function
18699 to guess if the generated parsers should have '.tab' in their
18701 (short_base_name): No longer static.
18703 * src/output.c (output_skeleton): New.
18704 (output): Disable call to output_master_parser, and give a try to
18705 a new skeleton handling system.
18706 (guards_output, actions_output): No longer static.
18707 (token_definitions_output, get_lines_number): No longer static.
18709 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
18711 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
18714 * src/parse-skel.y: New file.
18715 * src/scan-skel.l: New file.
18717 2001-12-29 Akim Demaille <akim@epita.fr>
18719 %name-prefix is broken.
18721 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
18722 Adjust all dependencies.
18723 * tests/headers.at (export YYLTYPE): Strengthen this test: use
18726 Renaming yylval but not yylloc is not consistent. Now we do.
18728 * src/bison.simple: Prefix yylloc if used.
18729 * doc/bison.texinfo (Decl Summary): Document that.
18731 2001-12-29 Akim Demaille <akim@epita.fr>
18733 * doc/bison.texinfo: Promote `%long-directive' over
18735 Remove all references to fixed-output-files, yacc is enough.
18737 2001-12-29 Akim Demaille <akim@epita.fr>
18739 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
18740 user prologue. These are defaults.
18741 * tests/actions.at (Mid-rule actions): Make sure the user can
18742 define YYDEBUG and YYERROR_VERBOSE.
18744 2001-12-29 Akim Demaille <akim@epita.fr>
18746 * src/output.c (header_output): Don't forget to export YYLTYPE and
18748 * tests/headers.at (export YYLTYPE): New, make sure it does.
18749 * tests/regression.at (%union and --defines, Invalid CPP headers):
18751 * tests/headers.at: here.
18753 2001-12-29 Akim Demaille <akim@epita.fr>
18755 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
18757 2001-12-29 Akim Demaille <akim@epita.fr>
18759 * tests/actions.at (Mid-rule actions): Output on a single line
18760 instead of several.
18762 2001-12-29 Akim Demaille <akim@epita.fr>
18764 * doc/bison.texinfo: Formatting changes.
18766 2001-12-29 Akim Demaille <akim@epita.fr>
18768 Don't store the token defs in a muscle, just be ready to output it
18769 on command. Now possible via `symbols'. Fixes a memory leak.
18771 * src/output.c (token_definitions_output): New.
18772 (output_parser, header_output): Use it.
18773 * src/reader.c (symbols_save): Remove.
18775 2001-12-29 Akim Demaille <akim@epita.fr>
18777 * src/bison.simple: Do not provide a default for YYSTYPE and
18778 YYLTYPE before the user's prologue. Otherwise it's hardly... a
18781 2001-12-29 Akim Demaille <akim@epita.fr>
18783 Mid-rule actions are simply... ignored!
18785 * src/reader.c (readgram): Be sure to attach mid-rule actions to
18786 the empty-rule associated to the dummy symbol, not to the host
18788 * tests/actions.at (Mid-rule actions): New.
18790 2001-12-29 Akim Demaille <akim@epita.fr>
18794 * src/reader.c (reader): Free grammar.
18796 2001-12-29 Akim Demaille <akim@epita.fr>
18800 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
18801 since it allocates it for each state, although only one is needed.
18802 (allocate_storage): Do it here.
18804 2001-12-29 Akim Demaille <akim@epita.fr>
18806 * src/options.h, src/options.c (create_long_option_table): Rename
18808 (long_option_table_new): this, with a clearer prototype.
18809 (percent_table): Remove, unused,
18810 * src/getargs.c (getargs): Adjust.
18812 2001-12-29 Akim Demaille <akim@epita.fr>
18814 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
18815 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
18818 2001-12-29 Akim Demaille <akim@epita.fr>
18820 * src/lalr.c (build_relations): Rename `states' as `states1'.
18821 Sorry, I don't understand exactly what it is, no better name...
18823 2001-12-29 Akim Demaille <akim@epita.fr>
18825 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
18826 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
18827 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
18830 2001-12-29 Akim Demaille <akim@epita.fr>
18832 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
18835 2001-12-29 Akim Demaille <akim@epita.fr>
18837 * src/reader.c, src/reader.h (user_toknums): Remove.
18838 Adjust all users to use symbols[i]->user_token_number.
18840 2001-12-29 Akim Demaille <akim@epita.fr>
18842 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
18843 Adjust all users to use symbols[i]->prec or ->assoc.
18845 2001-12-29 Akim Demaille <akim@epita.fr>
18847 * src/reader.c, src/reader.h (tags): Remove.
18848 Adjust all users to use symbols[i]->tag.
18850 2001-12-29 Akim Demaille <akim@epita.fr>
18852 * src/gram.h, src/gram.c (symbols): New, similar to state_table
18854 * src/reader.c (packsymbols): Fill this table.
18856 * src/conflicts.c (resolve_sr_conflict): Adjust.
18857 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
18859 Use symbols[i]->tag instead of tags[i].
18861 2001-12-29 Akim Demaille <akim@epita.fr>
18863 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
18864 In addition, put a comment in there, to replace...
18865 * tests/regression.at (%union and C comments): Remove.
18867 2001-12-29 Akim Demaille <akim@epita.fr>
18869 * tests/regression.at (Web2c Actions): Blindly move the actual
18870 output as expected output. The contents *seem* right to me, but I
18871 can't pretend reading perfectly parser tables... Nonetheless, all
18872 the other tests pass correctly, the table look OK, even though the
18873 presence of `$axiom' is to be noted: AFAICS it is useless (but
18876 2001-12-29 Akim Demaille <akim@epita.fr>
18878 * src/reader.c (readgram): Don't add the rule 0 if there were no
18879 rules read. In other words, add it _after_ having performed
18880 grammar sanity checks.
18881 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
18883 2001-12-29 Akim Demaille <akim@epita.fr>
18885 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
18886 visible, and some states have now a different number.
18888 2001-12-29 Akim Demaille <akim@epita.fr>
18890 * src/reader.c (readgram): Bind the initial rule's lineno to that
18892 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18893 (Solved SR Conflicts): Adjust rule 0's line number.
18895 2001-12-29 Akim Demaille <akim@epita.fr>
18897 Fix the `GAWK Grammar' failure.
18899 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18900 the reductions of the first state which was mistakenly confused
18901 with the final state because precisely final_state was initialized
18903 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18904 now noticed by Bison.
18905 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18906 have a reduction on $default.
18908 2001-12-29 Akim Demaille <akim@epita.fr>
18910 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18912 * src/closure.c (print_closure): Likewise.
18913 * src/derives.c (print_derives): Likewise.
18914 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18917 2001-12-29 Akim Demaille <akim@epita.fr>
18919 * src/lalr.c (lookaheads_print): New.
18920 (lalr): Call it when --trace-flag.
18921 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18924 2001-12-29 Akim Demaille <akim@epita.fr>
18926 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18927 when walking through ritem, even via rule->rhs.
18928 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18929 (useful_production, useless_nonterminals): Likewise.
18930 (reduce_grammar_tables): Likewise, plus update nritems.
18931 * src/nullable.c (set_nullable): Likewise.
18932 * src/lalr.c (build_relations): Likewise.
18933 * tests/sets.at (Nullable): Adjust.
18934 Fortunately, now, the $axiom is no longer nullable.
18936 2001-12-29 Akim Demaille <akim@epita.fr>
18938 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
18940 * src/gram.c (ritem_longest_rhs): Likewise.
18941 * src/reduce.c (nonterminals_reduce): Likewise.
18942 * src/print_graph.c (print_graph): Likewise.
18943 * src/output.c (output_rule_data): Likewise.
18944 * src/nullable.c (set_nullable): Likewise.
18946 2001-12-29 Akim Demaille <akim@epita.fr>
18948 * src/output.c: Comment changes.
18950 2001-12-27 Paul Eggert <eggert@twinsun.com>
18952 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18953 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18954 Sparc, as they were causing more porting problems than the
18955 (minor) performance improvement was worth.
18957 Also, catch up with 1.31's YYSTD.
18959 2001-12-27 Akim Demaille <akim@epita.fr>
18961 * src/output.c (output_gram): Rely on nritems, not the
18962 0-sentinel. See below.
18963 Use -1 as separator, not 0.
18964 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18965 Rely on -1 as separator in yyrhs, instead of 0.
18966 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18967 twice `Now at end of input', therefore there are two lines less to
18970 2001-12-27 Akim Demaille <akim@epita.fr>
18972 * tests/regression.at (Unresolved SR Conflicts):
18973 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18976 2001-12-27 Akim Demaille <akim@epita.fr>
18978 * src/LR0.c (new_state): Recognize the final state by the fact it
18979 is reached by eoftoken.
18980 (insert_start_shifting_state, insert_eof_shifting_state)
18981 (insert_accepting_state, augment_automaton): Remove, since now
18982 these states are automatically computed from the initial state.
18983 (generate_states): Adjust.
18984 * src/print.c: When reporting a rule number to the user, substract
18985 1, so that the axiom rule is rule 0, and the first user rule is 1.
18986 * src/reduce.c: Likewise.
18987 * src/print_graph.c (print_core): For the time being, just as for
18988 the report, depend upon --trace-flags to dump the full set of
18990 * src/reader.c (readgram): Once the grammar read, insert the rule
18991 0: `$axiom: START-SYMBOL $'.
18992 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18993 number of the states has changed (the final state is no longer
18994 necessarily the last), catch up.
18996 2001-12-27 Akim Demaille <akim@epita.fr>
18998 Try to make the use of the eoftoken valid. Given that its value
18999 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
19000 is used instead of > 0 where appropriate, (ii), depend upon nritems
19001 instead of the 0-sentinel.
19003 * src/gram.h, src/gram.c (nritems): New.
19004 Expected to be duplication of nitems, but for the time being...
19005 * src/reader.c (packgram): Assert nritems and nitems are equal.
19006 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
19007 * src/closure.c (print_closure, print_fderives): Likewise.

19009 * src/print.c (print_core, print_grammar): Likewise.
19010 * src/print_graph.c: Likewise.
19012 2001-12-27 Akim Demaille <akim@epita.fr>
19014 * src/main.c (main): If there are complains after grammar
19015 reductions, then output the report anyway if requested, then die.
19016 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
19017 * src/reader.c (eoftoken): New.
19018 (parse_token_decl): If the token being defined has value `0', it
19020 (packsymbols): No longer hack `tags' to insert `$' by hand.
19021 Be sure to preserve the value of the eoftoken.
19022 (reader): Make sure eoftoken is defined.
19023 Initialize nsyms to 0: now eoftoken is created just like the others.
19024 * src/print.c (print_grammar): Don't special case the eof token.
19025 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
19026 lie anyway, albeit pleasant.
19027 * tests/calc.at: Exercise error messages with eoftoken.
19028 Change the grammar so that empty input is invalid.
19029 Adjust expectations.
19030 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
19032 2001-12-27 Akim Demaille <akim@epita.fr>
19034 * configure.in: Check the protos of strchr ans strspn.
19035 Replace strchr if needed.
19036 * src/system.h: Provide the protos of strchr, strspn and memchr if
19038 * lib/strchr.c: New.
19039 * src/reader.c (symbols_save): Use strchr.
19041 2001-12-27 Akim Demaille <akim@epita.fr>
19043 * src/print.c, src/print_graph.c (escape): New.
19044 Use it to quote the TAGS outputs.
19045 * src/print_graph.c (print_state): Now errors are in red, and
19046 reductions in green.
19047 Prefer high to wide: output the state number on a line of its own.
19049 2001-12-27 Akim Demaille <akim@epita.fr>
19051 * src/state.h, src/state.c (reductions_new): New.
19052 * src/LR0.c (set_state_table): Let all the states have a
19053 `reductions', even if reduced to 0.
19054 (save_reductions): Adjust.
19055 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
19056 * src/print.c (print_reductions, print_actions): Adjust.

19061 * src/state.h, src/state.c (errs_new, errs_dup): New.
19062 * src/LR0.c (set_state_table): Let all the states have an errs,
19063 even if reduced to 0.
19064 * src/print.c (print_errs, print_reductions): Adjust.
19065 * src/output.c (output_actions, action_row): Adjust.
19066 * src/conflicts.c (resolve_sr_conflict): Adjust.

19072 2001-12-27 Akim Demaille <akim@epita.fr>
19074 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
19075 * src/print.c: here.
19076 (lookaheadset, shiftset): New, used as additional storage by
19078 (print_results): Adjust.
19079 (print_shifts, print_gotos, print_errs): New, extracted from...
19080 (print_actions): here.
19081 * src/print_graph.c (print_actions): Remove dead code.
19083 2001-12-27 Akim Demaille <akim@epita.fr>
19085 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
19088 2001-12-27 Akim Demaille <akim@epita.fr>
19090 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

19100 * src/reader.c (packgram): Catch nitems overflows.
19102 2001-12-27 Akim Demaille <akim@epita.fr>
19104 * src/files.c, src/files.h (guard_obstack): Remove.
19105 * src/output.c (output): Adjust.
19106 * src/reader.c (parse_braces): New, factoring...
19107 (copy_action, copy_guard): these two which are renamed as...
19108 (parse_action, parse_guard): these.
19109 As a voluntary consequence, using braces around guards is now
19112 2001-12-27 Akim Demaille <akim@epita.fr>
19114 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
19115 * src/reader.c (symbol_list): `guard' and `guard_line' are new
19117 (symbol_list_new): Adjust.
19118 (copy_action): action_line is the first line, not the last.
19119 (copy_guard): Just as for actions, store the `action' only, not
19120 the switch/case/break flesh.
19121 Don't parse the user action that might follow the guard, let...
19122 (readgram): do it, i.e., now, there can be an action after a
19124 In other words the guard is just explicitly optional.
19125 (packgram): Adjust.
19126 * src/output.c (guards_output): New.
19127 (output_parser): Call it when needed.
19128 (output): Also free the guard and attrs obstacks.
19129 * src/files.c, src/files.h (obstack_save): Remove.
19130 (output_files): Remove.
19131 As a result, if one needs the former `.act' file, using an
19132 appropriate skeleton which requires actions and guards is now
19134 * src/main.c (main): Adjust.
19135 * tests/semantic.at: New.
19136 * tests/regression.at: Use `input.y' as input file name.
19137 Avoid 8+3 problems by requiring input.c when the test needs the
19140 2001-12-27 Akim Demaille <akim@epita.fr>
19142 * src/reader.c (symbol_list_new): Be sure to initialize all the
19145 2001-12-27 Akim Demaille <akim@epita.fr>
19147 All the hacks using a final pseudo state are now useless.
19149 * src/LR0.c (set_state_table): state_table holds exactly nstates.
19150 * src/lalr.c (nLA): New.
19151 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
19152 instead of lookaheadsp from the pseudo state (nstate + 1).
19154 2001-12-27 Akim Demaille <akim@epita.fr>
19156 * src/output.c (action_row, token_actions): Use a state_t instead
19157 of a integer, and nlookaheads instead of the following state's
19160 2001-12-27 Akim Demaille <akim@epita.fr>
19162 * src/conflicts.c (log_resolution, flush_shift)
19163 (resolve_sr_conflict, set_conflicts, solve_conflicts)
19164 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
19165 (conflicts_print, print_reductions): Use a state_t instead of an
19166 integer when referring to a state.
19167 As much as possible, depend upon nlookaheads, instead of the
19168 `lookaheadsp' member of the following state (since lookaheads of
19169 successive states are successive, the difference between state n + 1
19170 and n served as the number of lookaheads for state n).
19171 * src/lalr.c (add_lookback_edge): Likewise.
19172 * src/print.c (print_core, print_actions, print_state)
19173 (print_results): Likewise.
19174 * src/print_graph.c (print_core, print_actions, print_state)
19175 (print_graph): Likewise.
19176 * src/conflicts.h: Adjust.
19178 2001-12-27 Akim Demaille <akim@epita.fr>
19180 * src/bison.hairy: Formatting/comment changes.
19182 Remove `register' indications.
19183 Add plenty of `static'.
19185 2001-12-27 Akim Demaille <akim@epita.fr>
19187 * src/output.c (prepare): Drop the muscle `ntbase' which
19188 duplicates ntokens.
19189 * src/bison.simple: Formatting/comment changes.
19190 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
19191 is an undocumented synonym.
19193 2001-12-22 Akim Demaille <akim@epita.fr>
19195 * src/output.c (output_table_data): Change the prototype to use
19196 `int' for array ranges: some invocations do pass an int, not a
19198 Reported by Wayne Green.
19200 2001-12-22 Akim Demaille <akim@epita.fr>
19202 Some actions of web2c.y are improperly triggered.
19203 Reported by Mike Castle.
19205 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
19206 * tests/regression.at (Web2c): Rename as...
19207 (Web2c Report): this.
19208 (Web2c Actions): New.
19210 2001-12-22 Akim Demaille <akim@epita.fr>
19212 Reductions in web2c.y are improperly reported.
19213 Reported by Mike Castle.
19215 * src/conflicts.c (print_reductions): Fix.
19216 * tests/regression.at (Web2c): New.
19218 2001-12-18 Akim Demaille <akim@epita.fr>
19220 Some host fail on `assert (!"foo")', which expands to
19221 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
19222 Reported by Nelson Beebee.
19224 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
19225 `#define it_succeeded 0' and `assert (it_succeeded)'.
19227 2001-12-17 Marc Autret <autret_m@epita.fr>
19229 * src/bison.simple: Don't hard code the skeleton line and filename.
19230 * src/output.c (output_parser): Rename 'line' as 'output_line'.
19231 New line counter 'skeleton_line' (skeleton-line muscle).
19233 2001-12-17 Paul Eggert <eggert@twinsun.com>
19235 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
19236 YYDEBUG must be defined to a nonzero value.
19238 * src/bison.simple (yytname): Do not assume that the user defines
19239 YYDEBUG to a properly parenthesized expression.
19241 2001-12-17 Akim Demaille <akim@epita.fr>
19243 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
19244 nlookaheads is a new member.
19246 * src/lalr.h (nlookaheads): Remove this orphan declaration.
19247 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
19250 2001-12-17 Akim Demaille <akim@epita.fr>
19252 * src/files.h, src/files.c (open_files, close_files): Remove.
19253 * src/main.c (main): Don't open/close files, nor invoke lex_free,
19255 * src/reader.c (reader): Do it.
19257 2001-12-17 Akim Demaille <akim@epita.fr>
19259 * src/conflicts.c (print_reductions): Formatting changes.
19261 2001-12-17 Akim Demaille <akim@epita.fr>
19263 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
19264 (flush_reduce): New.
19265 (resolve_sr_conflict): Adjust.
19267 2001-12-17 Akim Demaille <akim@epita.fr>
19269 * src/output.c (output_obstack): Be static and rename as...
19270 (format_obstack): this, to avoid any confusion with files.c's
19272 * src/reader.h (muscle_obstack): Move to...
19273 * src/output.h: here, since it's defined in output.c.
19275 2001-12-17 Akim Demaille <akim@epita.fr>
19277 * src/output.c (action_row, save_column, default_goto)
19278 (sort_actions, matching_state, pack_vector): Better variable
19281 2001-12-17 Akim Demaille <akim@epita.fr>
19283 * src/output.c: Various formatting changes.
19285 2001-12-17 Akim Demaille <akim@epita.fr>
19287 * src/files.c (output_files): Free the output_obstack.
19288 * src/main.c (main): Call print and print_graph conditionally.
19289 * src/print.c (print): Work unconditionally.
19290 * src/print_graph.c (print_graph): Work unconditionally.
19291 * src/conflicts.c (log_resolution): Output only if verbose_flag.
19293 2001-12-16 Marc Autret <autret_m@epita.fr>
19295 * src/output.c (actions_output): Fix. When we use %no-lines,
19296 there is one less line per action.
19298 2001-12-16 Marc Autret <autret_m@epita.fr>
19300 * src/bison.simple: Remove a useless #line directive.
19301 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
19302 * src/output.c (get_lines_number): New.
19303 (output_parser): Adjust, now takes care about the lines of a
19305 Fix line numbering.
19306 (actions_output): Computes the number of lines taken by actions.
19307 (output_master_parser): Insert new skeleton which is the name of
19308 the output parser file name.
19310 2001-12-15 Marc Autret <autret_m@epita.fr>
19312 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
19314 2001-12-15 Marc Autret <autret_m@epita.fr>
19316 * src/output.c (output_gram): Keep track of the hairy one.
19318 2001-12-15 Akim Demaille <akim@epita.fr>
19320 Make `make distcheck' work.
19322 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
19323 system.h which uses libgettext.h.
19325 2001-12-15 Akim Demaille <akim@epita.fr>
19327 * src/nullable.c (set_nullable): Useless rules must be skipped,
19328 otherwise, since we range over their symbols, we might look at a
19329 nonterminal which no longer ``exists'', i.e., it is not counted in
19330 `nvars', hence we overflow our arrays.
19332 2001-12-15 Akim Demaille <akim@epita.fr>
19334 The header can also be produced directly, without any obstack!
19337 * src/files.c, src/files.h (defines_obstack): Remove.
19338 (compute_header_macro): Global.
19339 (defines_obstack_save): Remove.
19340 * src/reader.c (parse_union_decl): No longer output to
19341 defines_obstack: its content can be found in the `stype' muscle
19343 (output_token_translations): Merge into...
19344 (symbols_output): this.
19346 (symbols_save): this.
19348 * src/output.c (header_output): New.
19351 2001-12-15 Akim Demaille <akim@epita.fr>
19353 * src/reader.c (parse_union_decl): Instead of handling two obstack
19354 simultaneously, use one to define the `stype' muscle, and use the
19355 value of the latter to fill defines_obstack.
19356 (copy_comment): Remove.
19357 (copy_comment2): Work for a single obstack.
19359 (copy_comment): this.
19361 2001-12-15 Akim Demaille <akim@epita.fr>
19363 * src/lex.c, src/lex.h (xgetc): No longer static.
19364 * src/reader.c (parse_union_decl): Revamp.
19366 2001-12-15 Akim Demaille <akim@epita.fr>
19368 Still making progress in separating Bison into (i) input, (ii)
19369 process, (iii) output: now we can directly output the parser file
19370 without using table_obstack at all.
19372 * src/files.c, src/files.h (table_obstack): Bye bye.
19373 (parser_file_name): New.
19374 * src/files.c (compute_output_file_names): Compute it.
19375 * src/output.c (actions_output, output_parser)
19376 (output_master_parser): To a file instead of an obstack.
19378 2001-12-15 Akim Demaille <akim@epita.fr>
19380 Attach actions to rules, instead of pre-outputting them to
19383 * src/gram.h (rule_t): action and action_line are new members.
19384 * src/reader.c (symbol_list): Likewise.
19385 (copy_action): Save the actions within the rule.
19386 (packgram): Save them in rule_table.
19387 * src/output.c (actions_output): New.
19388 (output_parser): Use it on `%%actions'.
19389 (output_rule_data): Don't free rule_table.
19391 (prepare): Don't save the `action' muscle.
19392 * src/bison.simple: s/%%action/%%actions/.
19394 2001-12-15 Akim Demaille <akim@epita.fr>
19396 * src/reader.c (copy_action): When --yacc, don't append a `;'
19397 to the user action: let it fail if lacking.
19398 Suggested by Arnold Robbins and Tom Tromey.
19400 2001-12-14 Akim Demaille <akim@epita.fr>
19402 * src/lex.c (literalchar): Simply return the char you decoded, non
19403 longer mess around with obstacks and int pointers.
19404 Adjust all callers.
19406 2001-12-14 Akim Demaille <akim@epita.fr>
19408 * src/lex.c (literalchar): Don't escape the special characters,
19409 just decode them, and keep them as char (before, eol was output as
19410 the 2 char string `\n' etc.).
19411 * src/output.c (output_rule_data): Use quotearg to output the
19414 2001-12-13 Paul Eggert <eggert@twinsun.com>
19416 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
19417 Do not infringe on the global user namespace when using C++.
19418 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
19419 All uses of `fprintf' and `stderr' changed.
19421 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
19423 2001-12-13 Akim Demaille <akim@epita.fr>
19425 The computation of nullable is broken: it doesn't handle empty
19428 * tests/torture.at (GNU AWK Grammar): New.
19429 * tests/sets.at (Nullable): New.
19430 * src/nullable.c (set_nullable): Instead of blindly looping over
19431 `ritems', loop over the rules, and then over their rhs's.
19433 Work around Autotest bugs.
19435 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
19436 frame, because Autotest understand lines starting with a `+' as
19437 traces from the shell. Then, they are not processed properly.
19438 Admittedly an Autotest bug, but we don't have time to wait for
19439 Autotest to catch up.
19440 * tests/regression.at (Broken Closure): Adjust to the new table
19443 * tests/sets.at: here.
19445 2001-12-13 Akim Demaille <akim@epita.fr>
19447 * src/closure.c (closure): Use nrules instead of playing tricks
19448 with BITS_PER_WORD.
19450 2001-12-13 Akim Demaille <akim@epita.fr>
19452 * src/print.c (print_actions): Output the handling of `$' as the
19453 traces do: shifting the token EOF. Before EOF was treated as a
19455 * tests/regression.at: Adjust some tests.
19456 * src/print_graph.c (print_core): Complete the set of items via
19457 closure. The next-to-final and final states are still unsatisfying,
19458 but that's to be addressed elsewhere.
19459 No longer output the rule numbers, but do output the state number.
19460 A single loop for the shifts + gotos is enough, but picked a
19461 distinct color for each.
19462 (print_graph): Initialize and finalize closure.
19464 2001-12-13 Akim Demaille <akim@epita.fr>
19466 * src/reader.c (readgram): Remove dead code, an strip useless
19468 (get_type): Remove, unused.
19470 2001-12-12 Akim Demaille <akim@epita.fr>
19472 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
19473 on that of lib/error.c.
19475 2001-12-12 Akim Demaille <akim@epita.fr>
19477 Some hosts don't like `/' in includes.
19479 * src/system.h: Include libgettext.h without qualifying the path.
19480 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
19483 2001-12-11 Marc Autret <autret_m@epita.fr>
19485 * src/output.c (output_parser): Remove useless muscle.
19487 2001-12-11 Marc Autret <autret_m@epita.fr>
19489 * src/bison.simple: Remove #line just before %%epilogue. It
19490 is now handled in ...
19491 * src/reader.c (read_additionnal_code): Add the output of a
19492 #line for the epilogue.
19494 2001-12-10 Marc Autret <autret_m@epita.fr>
19496 * src/reader.c (copy_definition): Re-use CPP-outed code which
19497 replace precedent remove.
19498 * src/bison.simple: Remove #line before %%prologue because
19499 %%input-line is wrong at this time.
19501 2001-12-10 Marc Autret <autret_m@epita.fr>
19503 * src/reader.c (symbols_output): Clean up.
19504 * src/output.c (output_gram, output): Clean up.
19506 2001-12-10 Akim Demaille <akim@epita.fr>
19508 * src/lalr.c (initialize_lookaheads): New. Extracted from...
19509 * src/LR0.c (set_state_table): here.
19510 * src/lalr.c (lalr): Call it.
19512 2001-12-10 Akim Demaille <akim@epita.fr>
19514 * src/state.h (shifts): Remove the `number' member: shifts are
19515 attached to state, hence no longer need to be labelled with a
19518 2001-12-10 Akim Demaille <akim@epita.fr>
19520 Now that states have a complete set of members, the linked list of
19521 shifts is useless: just fill directly the state's shifts member.
19523 * src/state.h (shifts): Remove the `next' member.
19524 * src/LR0.c (first_state, last_state): Remove.
19525 Adjust the callers.
19526 (augment_automaton): Don't look for the shifts that must be added
19527 a shift on EOF: it is those of the state we looked for! But now,
19528 since shifts are attached, it is no longer needed to looking
19529 merely by its id: its number.
19531 2001-12-10 Akim Demaille <akim@epita.fr>
19533 * src/LR0.c (augment_automaton): Better variable locality.
19534 Remove an impossible branch: if there is a state corresponding to
19535 the start symbol being shifted, then there is shift for the start
19536 symbol from the initial state.
19538 2001-12-10 Akim Demaille <akim@epita.fr>
19540 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
19541 only when appropriate: when insert_start_shifting_state' is not
19543 * tests/regression.at (Rule Line Numbers): Adjust.
19545 2001-12-10 Akim Demaille <akim@epita.fr>
19547 * src/LR0.c (augment_automaton): Now that all states have shifts,
19548 merge the two cases addition shifts to the initial state.
19550 2001-12-10 Akim Demaille <akim@epita.fr>
19552 * src/lalr.c (set_state_table): Move to...
19554 * src/lalr.c (lalr): Don't call it...
19555 * src/LR0.c (generate_states): do it.
19556 * src/LR0.h (first_state): Remove, only the table is used.
19558 2001-12-10 Akim Demaille <akim@epita.fr>
19560 * src/LR0.h (first_shift, first_reduction): Remove.
19561 * src/lalr.c: Don't use first_shift: find shifts through the
19564 2001-12-10 Akim Demaille <akim@epita.fr>
19566 * src/LR0.c: Attach shifts to states as soon as they are
19568 * src/lalr.c (set_state_table): Instead of assigning shifts to
19569 state, just assert that the mapping was properly done.
19571 2001-12-10 Akim Demaille <akim@epita.fr>
19573 * src/LR0.c (insert_start_shift): Rename as...
19574 (insert_start_shifting_state): this.
19575 (insert_eof_shifting_state, insert_accepting_state): New.
19576 (augment_automaton): Adjust.
19577 Better locality of the variables.
19578 When looking if the start_symbol is shifted from the initial
19579 state, using `while (... symbol != start_symbol ...)' sounds
19580 better than `while (... symbol < start_symbol ...)': If fail
19581 to see how the order between symbols could be relevant!
19583 2001-12-10 Akim Demaille <akim@epita.fr>
19585 * src/getargs.h: Don't declare `spec_name_prefix' and
19586 `spec_file_prefix', declared by src/files.h.
19587 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
19588 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
19589 * src/output.c (prepare): Adjust.
19590 * src/reader.c (symbols_output): Likewise.
19591 * src/vmsgetargs.c: Vaguely adjust, but who cares?
19593 2001-12-10 Akim Demaille <akim@epita.fr>
19595 * src/muscle_tab.c (muscle_init): NULL is a better default than
19598 2001-12-10 Akim Demaille <akim@epita.fr>
19600 * src/reader.c (reader): Calling symbols_output once is enough.
19602 2001-12-10 Akim Demaille <akim@epita.fr>
19604 Now that states have a complete set of members, the linked list of
19605 reductions is useless: just fill directly the state's reductions
19608 * src/state.h (struct reductions): Remove member `number' and
19610 * src/LR0.c (first_reduction, last_reduction): Remove.
19611 (save_reductions): Don't link the new reductions, store them in
19613 * src/lalr.c (set_state_table): No need to attach reductions to
19614 states, it's already done.
19615 * src/output.c (output_actions): No longer free the shifts, then
19616 the reductions, then the states: free all the states and their
19619 2001-12-10 Akim Demaille <akim@epita.fr>
19621 * src/options.c (OPTN, DRTV, BOTH): New.
19622 (option_table): Use them.
19624 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
19625 the job of system.h.
19626 * src/options.c: Don't include stdio.h and xalloc.h for the same
19629 2001-12-10 Akim Demaille <akim@epita.fr>
19631 * src/output.c (output, prepare): Make sure the values of the
19632 muscles `action' and `prologue' are 0-terminated.

19651 * tests/Makefile.am: Adjust.
19653 2001-12-10 Akim Demaille <akim@epita.fr>
19655 One structure for states is enough, even though theoretically
19656 there are LR(0) states and LALR(1) states.
19658 * src/lalr.h (state_t): Remove.
19659 (state_table): Be state_t **, not state_t *.
19660 * src/state.h (core, CORE_ALLOC): Rename as...
19661 (state_t, STATE_ALLOC): this.
19662 Add the LALR(1) members: shifts, reductions, errs.
19663 * src/LR0.c (state_table): Rename as...
19664 (state_hash): this, to avoid name clashes with the global
19666 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c

19669 2001-12-10 Akim Demaille <akim@epita.fr>
19671 Bison dumps core on bash.y.
19672 Reported by Pascal Bart.
19674 * src/warshall.c (bitmatrix_print): New.
19676 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
19677 j must be the outer loop.
19678 * tests/regression.at (Broken Closure): New.
19680 2001-12-05 Akim Demaille <akim@epita.fr>
19682 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
19684 Reported by Peter Hamorsky.

19694 2001-12-05 Akim Demaille <akim@epita.fr>
19696 * src/reduce.c (reduce_grammar_tables): No longer disable the
19697 removal of useless rules via CPP but via `if (0)', so that the
19698 compiler still check the code is valid.
19699 For instance, it should have noticed `rline' no longer exists: use
19700 the `line' member of rule_t.
19701 * src/gram.c (dummy, rline): Remove, unused.
19703 2001-12-05 Akim Demaille <akim@epita.fr>
19705 * src/output.c (pack_vector): Use assert, not berror.
19706 * src/main.c (berror): Remove, unused.
19708 2001-12-05 Akim Demaille <akim@epita.fr>
19710 New experimental feature: if --verbose --trace output all the
19711 items of a state, not only its kernel.
19713 * src/print.c (print_core): If `trace_flag', then invoke closure
19714 before outputting the items of the state (print_core is no longer
19715 a correct name them).
19716 (print_results): Invoke new_closure/free_closure if needed.
19718 2001-12-05 Akim Demaille <akim@epita.fr>
19720 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
19721 * src/closure.c, src/closure.h (itemsetsize): Rename as...

19727 (closure): Use it for printing input and output.
19729 2001-12-05 Akim Demaille <akim@epita.fr>
19731 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
19732 indexed by nonterminals.
19734 2001-12-05 Akim Demaille <akim@epita.fr>
19736 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

19752 2001-12-05 Akim Demaille <akim@epita.fr>
19754 * src/output.c (action_row): De-obfuscate
19755 using the good o' techniques: arrays not pointers, variable
19756 locality, BITISSET, RESETBIT etc.
19758 2001-12-05 Akim Demaille <akim@epita.fr>
19760 Pessimize the code to simplify it: from now on, all the states
19761 have a valid SHIFTS, which NSHIFTS is possibly 0.
19763 * src/LR0.c (shifts_new): Be global and move to..
19764 * src/state.c, src/state.h: here.
19765 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
19766 * src/print_graph: Adjust.
19768 2001-12-05 Akim Demaille <akim@epita.fr>
19770 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
19771 * src/conflicts.c: Use it.
19772 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
19773 incorrectly ``simplified''.
19775 2001-12-05 Akim Demaille <akim@epita.fr>
19777 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
19778 using the good o' techniques: arrays not pointers, variable
19779 locality, BITISSET, RESETBIT etc.
19781 2001-12-05 Akim Demaille <akim@epita.fr>
19783 * src/state.h (SHIFT_SYMBOL): New.
19784 * src/conflicts.c: Use it to deobfuscate.

19788 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
19789 (print_reductions): De-obfuscate using the good o' techniques:

19813 2001-12-05 Akim Demaille <akim@epita.fr>
19815 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
19816 * src/lalr.c: Use them.
19818 2001-12-05 Akim Demaille <akim@epita.fr>
19820 * src/LR0.c (augment_automaton): Formatting changes.
19821 Better variable locality.

19825 * src/lalr.c (matrix_print): New.
19826 (transpose): Use it.

19829 2001-12-05 Akim Demaille <akim@epita.fr>
19831 * src/lalr.c (maxrhs): Move to...
19832 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
19833 * src/lalr.c (build_relations): Adjust.
19835 2001-12-05 Akim Demaille <akim@epita.fr>
19837 * src/lalr.c (transpose): Free the memory allocated to the
19838 argument, as it is replaced by the results by the unique caller.
19839 (build_relations): Merely invoke transpose: it handles the memory
19841 Improve variable locality.
19842 Avoid variables used as mere abbreviations.
19843 (compute_lookaheads): Use arrays instead of pointers.
19845 2001-12-05 Akim Demaille <akim@epita.fr>
19847 * src/lalr.c (initialize_F): Improve variable locality.
19848 Avoid variables used as mere abbreviations.
19850 2001-12-05 Akim Demaille <akim@epita.fr>
19852 * src/derives.c (print_derives): Display the ruleno.
19853 * src/lalr.c (initialize_F, transpose): Better variable locality

19861 2001-12-05 Akim Demaille <akim@epita.fr>
19863 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
19864 the handling of squeue.
19865 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19867 2001-12-05 Akim Demaille <akim@epita.fr>
19869 Because useless nonterminals are now kept alive (instead of being
19870 `destroyed'), we now sometimes examine them, and store information
19871 related to them. Hence we need to know their number, and adjust
19872 memory allocations.
19874 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19876 * src/LR0.c (allocate_itemsets): The memory allocated to
19877 `symbol_count' was used for two different purpose: once to count
19878 the number of occurrences of each symbol, and later reassigned to
19879 `shift_symbol', containing the symbol that can be shifted from a
19881 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19883 (new_itemsets): Allocate `shift_symbol' here.
19884 (allocate_itemsets): symbol_count includes useless nonterminals.
19885 Make room for them.
19886 (free_storage): Use `free', not `XFREE', for pointers that cannot
19889 2001-12-05 Akim Demaille <akim@epita.fr>
19891 * src/nullable.c (set_nullable): Deobfuscate the handling of
19893 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19895 2001-12-05 Akim Demaille <akim@epita.fr>
19897 * src/gram.c, src/gram.h (ritem_print): New.
19898 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19899 (This useless function was defined only to work around VMS linkers
19900 that can't handle compilation units with variables only).
19901 * src/reduce.c (dump_grammar): Use it to trace the construction of
19904 2001-12-04 Paul Eggert <eggert@twinsun.com>
19906 * src/bison.simple (union yyalloc): Change member names
19907 to be the same as the stack names.
19908 (yyparse): yyptr is now union yyalloc *, not char *.
19909 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19910 and may generate better code on some machines.
19911 (yystpcpy): Use prototype if __STDC__ is defined, not just
19912 if __cplusplus is defined.
19914 2001-11-30 Akim Demaille <akim@epita.fr>
19916 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19917 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
19918 Gettext doesn't compile cleanly, and dies with -Werror.
19919 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
19920 Include WARNING_CFLAGS here.
19921 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
19922 before being defined.
19924 2001-11-27 Paul Eggert <eggert@twinsun.com>
19926 * lib/quotearg.h (quotearg_n, quotearg_n_style):
19927 First arg is int, not unsigned.
19928 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
19929 (SIZE_MAX, UINT_MAX): New macros.
19930 (quotearg_n_options): Abort if N is negative.
19931 Avoid overflow check on hosts where size_t is 64 bits and int
19932 is 32 bits, as overflow is impossible there.
19933 Fix off-by-one typo that caused unnecessary reallocation.
19935 2001-11-29 Paul Eggert <eggert@twinsun.com>
19937 Name space cleanup in generated parser.
19939 * doc/bison.texinfo (Bison Parser): Discuss system headers
19940 and their effect on the user name space.
19942 * src/bison.simple:
19943 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19944 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19945 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19947 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
19948 on user names when possible.
19950 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
19951 Simplify test for whather <alloca.h> exists.
19953 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
19955 (<stdio.h>): Include if YYDEBUG.
19957 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
19958 ! defined (yyoverflow) && ! defined (yymemcpy).
19960 (yymemcpy, yyparse): Rename local variables as needed so that
19961 they all begin with 'yy'.
19963 (yystrlen, yystpcpy): New functions.
19965 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
19968 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
19969 instead of relying on string.h functions. Use YYSTACK_ALLOC
19970 and YYSTACK_FREE instead of malloc and free.
19972 2001-11-30 Akim Demaille <akim@epita.fr>
19974 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
19975 before their first uses.

19978 2001-11-30 Akim Demaille <akim@epita.fr>
19980 * tests/reduce.at (Useless Nonterminals): Fix.
19982 2001-11-30 Akim Demaille <akim@epita.fr>
19984 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
19985 if body instead of `;' to pacify GCC's warnings.
19987 2001-11-30 Akim Demaille <akim@epita.fr>
19989 Instead of mapping the LHS of unused rules to -1, keep the LHS
19990 valid, but flag the rules as invalid.
19992 * src/gram.h (rule_t): `useful' is a new member.
19993 * src/print.c (print_grammar): Adjust.
19994 * src/derives.c (set_derives): Likewise.
19995 * src/reader.c (packgram, reduce_output): Likewise.
19996 * src/reduce.c (reduce_grammar_tables): Likewise.
19997 * tests/reduce.at (Underivable Rules, Useless Rules): New.
19999 2001-11-30 Akim Demaille <akim@epita.fr>
20001 * src/reduce.c (reduce_output): Formatting changes.
20002 * src/print.c (print_results, print_grammar): Likewise.
20003 * tests/regression.at (Rule Line Numbers)
20004 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
20006 2001-11-30 Akim Demaille <akim@epita.fr>
20008 * src/reduce.c (nonterminals_reduce): Instead of throwing away
20009 useless nonterminals, move them at the end of the symbol arrays.
20010 (reduce_output): Adjust.
20011 * tests/reduce.at (Useless Nonterminals): Adjust.
20013 2001-11-30 Akim Demaille <akim@epita.fr>

20018 (reduce_grammar): Call nonterminals_reduce.
20020 2001-11-29 Paul Eggert <eggert@twinsun.com>
20022 * src/bison.simple (YYSTACK_REALLOC): Remove.
20023 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
20024 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
20026 (union yyalloc): New type.
20027 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
20028 an arbitrary restriction on hosts where size_t is wider than int.
20030 (yyparse): Don't dump core if alloca or malloc fails; instead, report
20031 a parser stack overflow. Allocate just one block of memory for all
20032 three stacks, instead of allocating three blocks; this typically is
20033 faster and reduces fragmentation.
20035 Do not limit the number of items in the stack to a value that fits
20036 in 'int', as this is an arbitrary limit on hosts with 64-bit
20037 size_t and 32-bit int.
20039 2001-11-29 Marc Autret <autret_m@epita.fr>
20041 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
20042 of defining YYERROR_VERBOSE.

20055 * src/output.c (error_verbose): Define here.
20056 (prepare): Echo name modification.
20057 * src/getargs.h: Clean its extern declaration.
20058 * src/getargs.c (error_verbose_flag): Remove.

20087 2001-11-28 Akim Demaille <akim@epita.fr>
20089 * src/closure.c (closure): `b' and `ruleno' denote the same value:
20092 2001-11-28 Akim Demaille <akim@epita.fr>
20094 * src/closure.c (closure): Instead of looping over word in array
20095 then bits in words, loop over bits in array.
20097 2001-11-28 Akim Demaille <akim@epita.fr>
20099 * src/closure.c (closure): No longer optimize the special case
20100 where all the bits of `ruleset[r]' are set to 0, to make the code
20103 2001-11-28 Akim Demaille <akim@epita.fr>
20105 * src/closure.c (closure): `r' and `c' are new variables, used to
20106 de-obfuscate accesses to RULESET and CORE.
20108 2001-11-28 Akim Demaille <akim@epita.fr>
20110 * src/reduce.c (reduce_print): Use ngettext.

20119 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
20120 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
20121 as all tags are free'ed afterwards.
20122 From Enrico Scholz.
20124 2001-11-27 Paul Eggert <eggert@twinsun.com>
20126 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
20127 use alloca when we didn't want to, and vice versa.
20129 2001-11-27 Marc Autret <autret_m@epita.fr>
20131 * src/muscle_tab.c (muscle_init): Remove 'verbose' muscle

21849 New, from fileutils 4.0.37.
21850 * configure.in: Require Autoconf 2.49c. I took some time before

21874 s/\bENDFILE\b/tok_eof/g;
21875 s/\bIDENTIFIER\b/tok_identifier/g;
21877 Let them be enums, not #define, to ease debugging.

21901 introduces a guaranteed SEGV for semantic parsers.
21902 * doc/bison.texinfo: Document them.
21903 * tests/suite.at: Exercise these %options.

22124 * src/main.c (main): Don't use `atexit' to register `done', since
22125 it no longer has to remove tmp files, just call `output_files'
22126 when there are no errors.

22218 New files, from Fileutils 4.0.27.
22219 * src/main.c (printable_version): Remove.
22220 * src/lex.c, src/reader.c: Use `quote'.
22222 2000-10-04 Akim Demaille <akim@epita.fr>
22224 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
22226 2000-10-04 Akim Demaille <akim@epita.fr>
22228 * doc/bison.texinfo: Various typos spotted by Neil Booth.
22230 2000-10-04 Akim Demaille <akim@epita.fr>
22232 When a literal string is used to define two different tokens,
22233 `bison -v' segfaults.
22234 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
22236 * tests/regression.m4: New file.
22237 Include the core of the sample provided by Piotr Gackiewicz.
22238 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
22241 2000-10-04 Akim Demaille <akim@epita.fr>
22243 * src/reader.c (parse_expect_decl): Keep `count' within the size
22247 2000-10-02 Paul Eggert <eggert@twinsun.com>
22249 * bison.s1 (yyparse): Assign the default value
22250 unconditionally, to avoid a GCC warning and make the parser a
22253 2000-10-02 Akim Demaille <akim@epita.fr>
22255 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
22258 2000-10-02 Akim Demaille <akim@epita.fr>
22260 * src/derives.c, src/print.c, src/reduce.c: To ease the
22261 translation, move some `\n' out of the translated strings.
22263 2000-10-02 Akim Demaille <akim@epita.fr>
22265 The location tracking mechanism is precious for parse error
22266 messages. Nevertheless, it is enabled only when `@n' is used in
22267 the grammar, which is a different issue (you can use it in error
22268 message, but not in the grammar per se). Therefore, there should
22269 be another means to enable it.
22271 * src/getargs.c (getargs): Support `--locations'.
22272 (usage): Report it.
22273 * src/getargs.h (locationsflag): Export it.
22274 * src/lex.c (percent_table): Support `%locations'.
22275 * src/reader.c (yylsp_needed): Remove this variable, now replaced
22276 with `locationsflag'.
22277 * doc/bison.texinfo: Document `--locations' and `%locations'.
22279 * tests/calc.m4: Test it.
22281 For regularity of the names, replace each
22282 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
22283 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
22284 In addition replace each `flag' with `_flag'.
22286 2000-10-02 Akim Demaille <akim@epita.fr>
22288 Also test parse error messages, including with YYERROR_VERBOSE.
22290 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
22292 Use it to check the computations.
22293 Use it to check `nonassoc' is honored.
22294 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
22295 `--yyerror-verbose'.

22299 2000-10-02 Akim Demaille <akim@epita.fr>
22301 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22302 the latter demonstrates a flaw in the handling of non debugging
22303 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22304 was used in order to simplify:
22320 unfortunately this leads to a CPP conflict when
22321 `--name-prefix=foo' is used since it produces `#define yydebug
22324 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
22325 (YYDPRINTF): New macro.
22327 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
22329 Also test `--verbose', `--defines' and `--name-prefix'.

22333 Improve the readability of the produced parsers.
22335 * src/bison.s1: Formatting changes.
22336 Improve the comment related to the `$' mark.
22337 (yydefault): Don't fall through to `yyresume': `goto' there.
22338 * src/output.c (output_parser): When the `$' is met, skip the end
22340 New variable, `number_of_dollar_signs', to check there's exactly
22341 one `$' in the parser skeleton.
22343 2000-10-02 Akim Demaille <akim@epita.fr>
22345 * lib/xstrdup.c: New file, from the fileutils.
22346 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
22347 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
22348 instead of strlen + xmalloc + strcpy.
22349 * src/symtab.c (copys): Remove, use xstrdup instead.
22351 2000-10-02 Akim Demaille <akim@epita.fr>
22353 * src/gram.h (associativity): New enum type which replaces the
22354 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
22355 `right_assoc', `left_assoc' and `non_assoc'.
22356 Adjust all dependencies.
22357 * src/reader.c: Formatting changes.
22358 (LTYPESTR): Don't define it, use it as a literal in
22359 `reader_output_yylsp'.
22360 * src/symtab.h (symbol_class): New enum type which replaces the
22361 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
22362 `sunknown', `stoken and `snterm'.
22364 2000-10-02 Akim Demaille <akim@epita.fr>
22366 * src/getargs.c (fixed_outfiles): Rename as...
22367 (yaccflag): for consistency and accuracy.
22368 Adjust dependencies.
22370 2000-10-02 Akim Demaille <akim@epita.fr>
22372 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22373 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22374 difficult and introduced a lot of core dump. It turns out that
22375 Bison used an implementation of `xmalloc' based on `calloc', and
22376 at various places it does depend upon the initialization to 0. I
22377 have not tried to isolate the pertinent places, and all the former
22378 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
22379 someone should address this issue.
22381 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
22382 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

22394 2000-10-02 Akim Demaille <akim@epita.fr>

22401 Add support for `--statistics'.

22439 * src/reduce.c: Topological sort and other formatting changes.
22440 (bool, TRUE, FALSE): Move their definition to...

22445 * src/files.c: Formatting changes.
22446 (tryopen, tryclose, openfiles): Rename as...

22476 * src/output.c (token_actions): Introduce a temporary array,
22477 YYDEFACT, that makes it possible for this function to use
22478 output_short_table.
22480 2000-10-02 Akim Demaille <akim@epita.fr>
22482 `user_toknums' is output as a `short[]' in `output.c', while it is
22483 defined as a `int[]' in `reader.c'. For consistency with the
22484 other output tables, `user_toknums' is now defined as a table of

23461 * src/reader.c (reader_output_yylsp):
23463 (readgram): Use `#if 0' around code that accepted %command
23464 inside grammar rules: The documentation doesn't allow it,
23465 and it will fail since the %command processors scan for the next %.
23466 (parse_token_decl): Extended the %token
23467 declaration to allow a multi-character symbol as an alias.
23468 (parse_thong_decl): New function.
23469 (read_declarations): Added %thong declarations.
23470 (read_declarations): Handle NOOP to deal with allowing
23471 % declarations as another means to specify the flags.

23475 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
23476 (get_type_name, copy_guard, copy_action, readgram)
23477 (get_type, packsymbols): Revised most error messages.
23478 Changed `fatal' to `warnxxx' to avoid aborting for error.
23479 Revised and use multiple warnxxx functions to avoid using VARARGS1.
23480 (read_declarations): Improve the error message for
23481 an invalid character. Do not abort.
23482 (read_declarations, copy_guard, copy_action): Use
23483 printable_version to avoid unprintable characters in printed output.
23484 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
23485 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
23486 Allow the type of a non-terminal can be given
23487 more than once, as long as all specifications give the same type.
23490 (output_headers, output_trailers, output, output_gram)
23491 (output_rule_data): Implement noparserflag variable.
23492 Implement toknumflag variable.

23508 (literalchar); new function to deal with reading \ escapes.
23509 (lex): Use literalchar.
23510 (lex): Implemented "..." tokens.
23511 (literalchar, lex, parse_percent_token): Made tokenbuffer
23512 always contain the token. This includes growing the token
23513 buffer while reading an integer.
23514 (parse_percent_token): Replaced if-else statement with percent_table.
23515 (parse_percent_token): Added % declarations as another
23516 way to specify the flags -n, -l, and -r. Also added hooks for
23517 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
23518 major changes to files.c.
23519 (lex) Retain in the incoming stream a character following
23521 (skip_white_space, lex): Revised most error messages
23522 and changed fatal to warn to avoid aborting.

23525 * src/gram.h: Comment changes.
23527 * src/files.c (openfiles, open_extra_files, done):
