1607 usable in M4, rename the muscles using `-' to `_'.

1618 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
1619 shamelessly stolen from CVS Autoconf.
1621 2002-02-05 Akim Demaille <akim@epita.fr>
1623 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
1624 * configure.in: Check for the declarations of free and malloc.
1625 * src/muscle_tab.c: Adjust.
1627 2002-02-05 Akim Demaille <akim@epita.fr>
1629 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
1630 which have no values.
1632 2002-02-05 Akim Demaille <akim@epita.fr>
1634 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
1637 2002-01-29 Paul Eggert <eggert@twinsun.com>
1639 * src/bison.simple (YYSIZE_T): Do not define merely because
1640 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
1641 On some platforms, <alloca.h> does not declare YYSTD (size_t).
1643 2002-01-27 Akim Demaille <akim@epita.fr>
1645 Fix `%nonassoc and eof'.
1647 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
1648 which were not properly copied! Replace
1649 memcpy (res->errs, src->errs, src->nerrs);
1651 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
1653 * tests/regression.at (%nonassoc and eof): Adjust to newest
1654 Autotest: `.' is not in the PATH.
1656 2002-01-27 Akim Demaille <akim@epita.fr>
1658 * tests/sets.at (AT_EXTRACT_SETS): New.
1662 2002-01-26 Akim Demaille <akim@epita.fr>
1664 * tests/actions.at, tests/calc.at, tests/headers.at,
1665 * tests/torture.at: Adjust to the newest Autotest which no longer
1666 forces `.' in the PATH.
1668 2002-01-25 Akim Demaille <akim@epita.fr>
1670 * tests/regression.at (%nonassoc and eof): New.
1671 Suggested by Robert Anisko.
1673 2002-01-24 Akim Demaille <akim@epita.fr>
1675 Bison dumps core when trying to complain about broken input files.
1676 Reported by Cris van Pelt.
1678 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
1679 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
1681 (Invalid inputs): Strengthen: exercise parse_percent_token.
1683 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
1685 * src/Makefile.am: Add bison.c++.
1686 * src/bison.c++: New skeleton.
1688 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
1692 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
1694 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
1696 2002-01-20 Marc Autret <marc@gnu.org>
1698 * src/files.c (compute_output_file_names): Fix
1700 2002-01-20 Marc Autret <marc@gnu.org>
1702 * tests/output.at: New test.
1703 * src/files.c (compute_base_names): Don't map extensions when
1704 the YACC flag is set, use defaults.
1705 Reported by Evgeny Stambulchik.
1707 2002-01-20 Marc Autret <marc@gnu.org>
1709 * src/system.h: Need to define __attribute__ away for non-GCC
1710 compilers as well (i.e. the vendor C compiler).
1711 Suggested by Albert Chin-A-Young.
1713 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
1715 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
1716 canonical definition.
1717 * src/system.h: Use the canonical definition for PARAMS (avoids
1718 a conflict with the macro from lib/hash.h).
1720 2002-01-11 Akim Demaille <akim@epita.fr>
1722 * configure.in: Use AC_FUNC_STRNLEN.
1723 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
1725 2002-01-09 Akim Demaille <akim@epita.fr>
1727 * src/files.c, src/files.h (output_infix): New.
1728 (tab_extension): Remove.
1729 (compute_base_names): Compute the former, drop the latter.
1730 * src/output.c (prepare): Insert the muscles `output-infix', and
1732 * src/parse-skel.y (string, string.1): New.
1733 (section.header): Use it.
1734 (section.yacc): Remove.
1735 (prefix): Remove too.
1736 * src/scan-skel.l: Adjust.
1737 * src/bison.simple, src/bison.hairy: Adjust.
1739 2002-01-09 Akim Demaille <akim@epita.fr>
1741 * configure.in (WERROR_CFLAGS): Compute it.
1742 * src/Makefile.am (CFLAGS): Pass it.
1743 * tests/atlocal.in (CFLAGS): Idem.
1744 * src/files.c: Fix a few warnings.
1745 (get_extension_index): Remove, unused.
1747 2002-01-08 Akim Demaille <akim@epita.fr>
1749 * src/getargs.c (AS_FILE_NAME): New.
1750 (getargs): Use it to convert DOSish file names.
1751 * src/files.c (base_name): Rename as full_base_name to avoid
1752 clashes with `base_name ()'.
1753 (filename_split): New.
1754 (compute_base_names): N-th rewrite, using filename_split.
1756 2002-01-08 Akim Demaille <akim@epita.fr>
1758 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
1759 New, stolen from the Fileutils 4.1.
1760 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
1761 * configure.in: Check for the presence of memrchr, and of its
1764 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
1766 * lib/hash.h (__P): Added definition for this macro.
1767 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
1768 BUILT_SOURCES, to ensure they are generated first.
1769 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
1770 %error-verbose to allow bootstrapping with bison 1.30x.
1772 2002-01-06 Akim Demaille <akim@epita.fr>
1774 * src/reader.c (parse_braces): Don't fetch the next char, the
1775 convention is to fetch on entry.
1776 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
1777 'switch' without a following semicolon.
1778 * tests/regression.at (braces parsing): New.
1780 2002-01-06 Akim Demaille <akim@epita.fr>
1782 Bison is dead wrong in its RR conflict reports.
1784 * tests/torture.at (GNU Cim Grammar): New.
1785 * src/conflicts.c (count_rr_conflicts): Fix.
1787 2002-01-06 Akim Demaille <akim@epita.fr>
1789 Creating package.m4 from configure.ac causes too many problems.
1791 * tests/Makefile.am (package.m4): Create it by hand,
1792 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
1794 2002-01-06 Akim Demaille <akim@epita.fr>
1796 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
1799 2002-01-04 Paul Eggert <eggert@twinsun.com>
1801 * doc/bison.texinfo (Debugging):
1802 Remove YYSTDERR; it's no longer defined or used.
1803 Also, s/cstdio.h/cstdio/.
1805 2002-01-03 Akim Demaille <akim@epita.fr>
1807 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
1809 2002-01-03 Akim Demaille <akim@epita.fr>
1811 * src/parse-skel.y (process_skeleton): Don't bind the parser's
1812 tracing code to --trace, wait for a better --trace option, with
1815 2002-01-03 Akim Demaille <akim@epita.fr>
1817 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
1818 The ISO C++ standard is extremely clear about it: stderr is
1819 considered a macro, not a regular symbol (see table 94 `Header
1820 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
1821 Therefore std:: does not apply to it. It still does with fprintf.
1822 Also, s/cstdio.h/cstdio/.
1824 2002-01-03 Akim Demaille <akim@epita.fr>
1826 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
1827 for non system headers.
1829 2002-01-02 Akim Demaille <akim@epita.fr>
1831 Equip the skeleton chain with location tracking, runtime trace,
1832 pure parser and scanner.
1834 * src/parse-skel.y: Request a pure parser, locations, and prefix
1836 (%union): Having several members with the same type does not help
1837 type mismatches, simplify.
1838 (YYPRINT, yyprint): New.
1839 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
1842 * src/scan-skel.l: Adjust to these changes.
1843 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
1844 (LOCATION_PRINT, skel_control_t): New.
1846 2001-12-30 Akim Demaille <akim@epita.fr>
1848 * src/parse-skel.y: Get rid of the shift/reduce conflict:
1849 replace `gb' with BLANKS.
1850 * src/scan-skel.l: Adjust.
1852 2001-12-30 Akim Demaille <akim@epita.fr>
1854 * src/system.h: We don't need nor want bcopy.
1855 Throw away MS-DOS crap: we don't need getpid.
1856 * configure.in: We don't need strndup. It was even causing
1857 problems: because Flex includes the headers *before* us,
1858 _GNU_SOURCE is not defined by config.h, and therefore strndup was
1860 * lib/xstrndup.c: New.
1861 * src/scan-skel.l: Use it.
1862 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
1863 * src/parse-skel.y: Use %directives instead of #defines.
1865 2001-12-30 Akim Demaille <akim@epita.fr>
1867 * src/skeleton.h: New.
1868 * src/output.c (output_parser, output_master_parser): Remove, dead
1870 * src/output.h (get_lines_number, actions_output, guards_output)
1871 (token_definitions_output): Prototype them.
1872 * src/parse-skel.y: Add the license notice.
1873 Include output.h and skeleton.h.
1874 (process_skeleton): Returns void, and takes a single parameter.
1875 * src/scan-skel.l: Add the license notice.
1877 Don't use %option yylineno: it seems that then Flex imagines
1878 REJECT has been used, and therefore it won't reallocate its
1879 buffers (which makes no other sense to me than a bug). It results
1880 in warnings for `unused: yy_flex_realloc'.
1882 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
1884 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
1885 (MUSCLE_INSERT_PREFIX): ...to there.
1886 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
1887 (MUSCLE_INSERT_PREFIX): Move from here...
1889 * src/bison.hairy: Add a section directive. Put braces around muscle
1890 names. This parser skeleton is still broken, but Bison should not
1891 choke on a bad muscle 'syntax'.
1892 * src/bison.simple: Add a section directive. Put braces around muscle
1895 * src/files.h (strsuffix, stringappend): Add declarations.
1896 (tab_extension): Add declaration.
1897 (short_base_name): Add declaration.
1899 * src/files.c (strsuffix, stringappend): No longer static. These
1900 functions are used in the skeleton parser.
1901 (tab_extension): New.
1902 (compute_base_names): Use the computations done in this function
1903 to guess if the generated parsers should have '.tab' in their
1905 (short_base_name): No longer static.
1907 * src/output.c (output_skeleton): New.
1908 (output): Disable call to output_master_parser, and give a try to
1909 a new skeleton handling system.
1910 (guards_output, actions_output): No longer static.
1911 (token_definitions_output, get_lines_number): No longer static.
1913 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
1915 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
1918 * src/parse-skel.y: New file.
1919 * src/scan-skel.l: New file.
1921 2001-12-29 Akim Demaille <akim@epita.fr>
1923 %name-prefix is broken.
1925 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
1926 Adjust all dependencies.
1927 * tests/headers.at (export YYLTYPE): Strengthen this test: use
1930 Renaming yylval but not yylloc is not consistent. Now we do.
1932 * src/bison.simple: Prefix yylloc if used.
1933 * doc/bison.texinfo (Decl Summary): Document that.
1935 2001-12-29 Akim Demaille <akim@epita.fr>
1937 * doc/bison.texinfo: Promote `%long-directive' over
1939 Remove all references to fixed-output-files, yacc is enough.
1941 2001-12-29 Akim Demaille <akim@epita.fr>
1943 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
1944 user prologue. These are defaults.
1945 * tests/actions.at (Mid-rule actions): Make sure the user can
1946 define YYDEBUG and YYERROR_VERBOSE.
1948 2001-12-29 Akim Demaille <akim@epita.fr>
1950 * src/output.c (header_output): Don't forget to export YYLTYPE and
1952 * tests/headers.at (export YYLTYPE): New, make sure it does.
1953 * tests/regression.at (%union and --defines, Invalid CPP headers):
1955 * tests/headers.at: here.
1957 2001-12-29 Akim Demaille <akim@epita.fr>
1959 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
1961 2001-12-29 Akim Demaille <akim@epita.fr>
1963 * tests/actions.at (Mid-rule actions): Output on a single line
1966 2001-12-29 Akim Demaille <akim@epita.fr>
1968 * doc/bison.texinfo: Formatting changes.
1970 2001-12-29 Akim Demaille <akim@epita.fr>
1972 Don't store the token defs in a muscle, just be ready to output it
1973 on command. Now possible via `symbols'. Fixes a memory leak.
1975 * src/output.c (token_definitions_output): New.
1976 (output_parser, header_output): Use it.
1977 * src/reader.c (symbols_save): Remove.
1979 2001-12-29 Akim Demaille <akim@epita.fr>
1981 * src/bison.simple: Do not provide a default for YYSTYPE and
1982 YYLTYPE before the user's prologue. Otherwise it's hardly... a
1985 2001-12-29 Akim Demaille <akim@epita.fr>
1987 Mid-rule actions are simply... ignored!
1989 * src/reader.c (readgram): Be sure to attach mid-rule actions to
1990 the empty-rule associated to the dummy symbol, not to the host
1992 * tests/actions.at (Mid-rule actions): New.
1994 2001-12-29 Akim Demaille <akim@epita.fr>
1998 * src/reader.c (reader): Free grammar.
2000 2001-12-29 Akim Demaille <akim@epita.fr>
2004 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
2005 since it allocates it for each state, although only one is needed.
2006 (allocate_storage): Do it here.
2008 2001-12-29 Akim Demaille <akim@epita.fr>
2010 * src/options.h, src/options.c (create_long_option_table): Rename
2012 (long_option_table_new): this, with a clearer prototype.
2013 (percent_table): Remove, unused,
2014 * src/getargs.c (getargs): Adjust.
2016 2001-12-29 Akim Demaille <akim@epita.fr>
2018 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
2019 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
2022 2001-12-29 Akim Demaille <akim@epita.fr>
2024 * src/lalr.c (build_relations): Rename `states' as `states1'.
2025 Sorry, I don't understand exactly what it is, no better name...
2027 2001-12-29 Akim Demaille <akim@epita.fr>
2029 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
2030 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
2031 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
2034 2001-12-29 Akim Demaille <akim@epita.fr>
2036 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
2039 2001-12-29 Akim Demaille <akim@epita.fr>
2041 * src/reader.c, src/reader.h (user_toknums): Remove.
2042 Adjust all users to use symbols[i]->user_token_number.
2044 2001-12-29 Akim Demaille <akim@epita.fr>
2046 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
2047 Adjust all users to use symbols[i]->prec or ->assoc.
2049 2001-12-29 Akim Demaille <akim@epita.fr>
2051 * src/reader.c, src/reader.h (tags): Remove.
2052 Adjust all users to use symbols[i]->tag.
2054 2001-12-29 Akim Demaille <akim@epita.fr>
2056 * src/gram.h, src/gram.c (symbols): New, similar to state_table
2058 * src/reader.c (packsymbols): Fill this table.
2060 * src/conflicts.c (resolve_sr_conflict): Adjust.
2061 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
2063 Use symbols[i]->tag instead of tags[i].
2065 2001-12-29 Akim Demaille <akim@epita.fr>
2067 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
2068 In addition, put a comment in there, to replace...
2069 * tests/regression.at (%union and C comments): Remove.
2071 2001-12-29 Akim Demaille <akim@epita.fr>
2073 * tests/regression.at (Web2c Actions): Blindly move the actual
2074 output as expected output. The contents *seem* right to me, but I
2075 can't pretend reading perfectly parser tables... Nonetheless, all
2076 the other tests pass correctly, the table look OK, even though the
2077 presence of `$axiom' is to be noted: AFAICS it is useless (but
2080 2001-12-29 Akim Demaille <akim@epita.fr>
2082 * src/reader.c (readgram): Don't add the rule 0 if there were no
2083 rules read. In other words, add it _after_ having performed
2084 grammar sanity checks.
2085 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
2087 2001-12-29 Akim Demaille <akim@epita.fr>
2089 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
2090 visible, and some states have now a different number.
2092 2001-12-29 Akim Demaille <akim@epita.fr>
2094 * src/reader.c (readgram): Bind the initial rule's lineno to that
2096 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
2097 (Solved SR Conflicts): Adjust rule 0's line number.
2099 2001-12-29 Akim Demaille <akim@epita.fr>
2101 Fix the `GAWK Grammar' failure.
2103 * src/LR0.c (final_state): Initialize to -1 so that we do compute
2104 the reductions of the first state which was mistakenly confused
2105 with the final state because precisely final_state was initialized
2107 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
2108 now noticed by Bison.
2109 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
2110 have a reduction on $default.
2112 2001-12-29 Akim Demaille <akim@epita.fr>
2114 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
2116 * src/closure.c (print_closure): Likewise.
2117 * src/derives.c (print_derives): Likewise.
2118 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
2121 2001-12-29 Akim Demaille <akim@epita.fr>
2123 * src/lalr.c (lookaheads_print): New.
2124 (lalr): Call it when --trace-flag.
2125 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
2128 2001-12-29 Akim Demaille <akim@epita.fr>
2130 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
2131 when walking through ritem, even via rule->rhs.
2132 * src/reduce.c (dump_grammar, useful_production, reduce_output)
2133 (useful_production, useless_nonterminals): Likewise.
2134 (reduce_grammar_tables): Likewise, plus update nritems.
2135 * src/nullable.c (set_nullable): Likewise.
2136 * src/lalr.c (build_relations): Likewise.
2137 * tests/sets.at (Nullable): Adjust.
2138 Fortunately, now, the $axiom is no longer nullable.
2140 2001-12-29 Akim Demaille <akim@epita.fr>
2142 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
2144 * src/gram.c (ritem_longest_rhs): Likewise.
2145 * src/reduce.c (nonterminals_reduce): Likewise.
2146 * src/print_graph.c (print_graph): Likewise.
2147 * src/output.c (output_rule_data): Likewise.
2148 * src/nullable.c (set_nullable): Likewise.
2150 2001-12-29 Akim Demaille <akim@epita.fr>
2152 * src/output.c: Comment changes.
2154 2001-12-27 Paul Eggert <eggert@twinsun.com>
2156 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
2157 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
2158 Sparc, as they were causing more porting problems than the
2159 (minor) performance improvement was worth.
2161 Also, catch up with 1.31's YYSTD.
2163 2001-12-27 Akim Demaille <akim@epita.fr>
2165 * src/output.c (output_gram): Rely on nritems, not the
2166 0-sentinel. See below.
2167 Use -1 as separator, not 0.
2168 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
2169 Rely on -1 as separator in yyrhs, instead of 0.
2170 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
2171 twice `Now at end of input', therefore there are two lines less to
2174 2001-12-27 Akim Demaille <akim@epita.fr>
2176 * tests/regression.at (Unresolved SR Conflicts):
2177 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
2180 2001-12-27 Akim Demaille <akim@epita.fr>
2182 * src/LR0.c (new_state): Recognize the final state by the fact it
2183 is reached by eoftoken.
2184 (insert_start_shifting_state, insert_eof_shifting_state)
2185 (insert_accepting_state, augment_automaton): Remove, since now
2186 these states are automatically computed from the initial state.
2187 (generate_states): Adjust.
2188 * src/print.c: When reporting a rule number to the user, substract
2189 1, so that the axiom rule is rule 0, and the first user rule is 1.
2190 * src/reduce.c: Likewise.
2191 * src/print_graph.c (print_core): For the time being, just as for
2192 the report, depend upon --trace-flags to dump the full set of
2194 * src/reader.c (readgram): Once the grammar read, insert the rule
2195 0: `$axiom: START-SYMBOL $'.
2196 * tests/set.at: Adjust: rule 0 is now displayed, and since the
2197 number of the states has changed (the final state is no longer
2198 necessarily the last), catch up.
2200 2001-12-27 Akim Demaille <akim@epita.fr>
2202 Try to make the use of the eoftoken valid. Given that its value
2203 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
2204 is used instead of > 0 where appropriate, (ii), depend upon nritems
2205 instead of the 0-sentinel.
2207 * src/gram.h, src/gram.c (nritems): New.
2208 Expected to be duplication of nitems, but for the time being...
2209 * src/reader.c (packgram): Assert nritems and nitems are equal.
2210 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
2211 * src/closure.c (print_closure, print_fderives): Likewise.
2212 * src/gram.c (ritem_print): Likewise.
2213 * src/print.c (print_core, print_grammar): Likewise.
2214 * src/print_graph.c: Likewise.
2216 2001-12-27 Akim Demaille <akim@epita.fr>
2218 * src/main.c (main): If there are complains after grammar
2219 reductions, then output the report anyway if requested, then die.
2220 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
2221 * src/reader.c (eoftoken): New.
2222 (parse_token_decl): If the token being defined has value `0', it
2224 (packsymbols): No longer hack `tags' to insert `$' by hand.
2225 Be sure to preserve the value of the eoftoken.
2226 (reader): Make sure eoftoken is defined.
2227 Initialize nsyms to 0: now eoftoken is created just like the others.
2228 * src/print.c (print_grammar): Don't special case the eof token.
2229 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
2230 lie anyway, albeit pleasant.
2231 * tests/calc.at: Exercise error messages with eoftoken.
2232 Change the grammar so that empty input is invalid.
2233 Adjust expectations.
2234 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
2236 2001-12-27 Akim Demaille <akim@epita.fr>
2238 * configure.in: Check the protos of strchr ans strspn.
2239 Replace strchr if needed.
2240 * src/system.h: Provide the protos of strchr, strspn and memchr if
2242 * lib/strchr.c: New.
2243 * src/reader.c (symbols_save): Use strchr.
2245 2001-12-27 Akim Demaille <akim@epita.fr>
2247 * src/print.c, src/print_graph.c (escape): New.
2248 Use it to quote the TAGS outputs.
2249 * src/print_graph.c (print_state): Now errors are in red, and
2250 reductions in green.
2251 Prefer high to wide: output the state number on a line of its own.
2253 2001-12-27 Akim Demaille <akim@epita.fr>
2255 * src/state.h, src/state.c (reductions_new): New.
2256 * src/LR0.c (set_state_table): Let all the states have a
2257 `reductions', even if reduced to 0.

2260 * src/print.c (print_reductions, print_actions): Adjust.
2261 * src/output.c (action_row): Adjust.
2263 2001-12-27 Akim Demaille <akim@epita.fr>
2265 * src/state.h, src/state.c (errs_new, errs_dup): New.
2266 * src/LR0.c (set_state_table): Let all the states have an errs,
2267 even if reduced to 0.

2270 * src/conflicts.c (resolve_sr_conflict): Adjust.
2272 2001-12-27 Akim Demaille <akim@epita.fr>
2274 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
2276 2001-12-27 Akim Demaille <akim@epita.fr>
2278 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
2279 * src/print.c: here.
2280 (lookaheadset, shiftset): New, used as additional storage by
2282 (print_results): Adjust.
2283 (print_shifts, print_gotos, print_errs): New, extracted from...
2284 (print_actions): here.
2285 * src/print_graph.c (print_actions): Remove dead code.
2287 2001-12-27 Akim Demaille <akim@epita.fr>
2289 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
2292 2001-12-27 Akim Demaille <akim@epita.fr>
2294 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

2299 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
2302 2001-12-27 Akim Demaille <akim@epita.fr>
2304 * src/reader.c (packgram): Catch nitems overflows.
2306 2001-12-27 Akim Demaille <akim@epita.fr>
2308 * src/files.c, src/files.h (guard_obstack): Remove.
2309 * src/output.c (output): Adjust.
2310 * src/reader.c (parse_braces): New, factoring...
2311 (copy_action, copy_guard): these two which are renamed as...
2312 (parse_action, parse_guard): these.
2313 As a voluntary consequence, using braces around guards is now
2316 2001-12-27 Akim Demaille <akim@epita.fr>
2318 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
2319 * src/reader.c (symbol_list): `guard' and `guard_line' are new
2321 (symbol_list_new): Adjust.
2322 (copy_action): action_line is the first line, not the last.
2323 (copy_guard): Just as for actions, store the `action' only, not
2324 the switch/case/break flesh.
2325 Don't parse the user action that might follow the guard, let...
2326 (readgram): do it, i.e., now, there can be an action after a
2328 In other words the guard is just explicitly optional.
2330 * src/output.c (guards_output): New.
2331 (output_parser): Call it when needed.
2332 (output): Also free the guard and attrs obstacks.
2333 * src/files.c, src/files.h (obstack_save): Remove.
2334 (output_files): Remove.
2335 As a result, if one needs the former `.act' file, using an
2336 appropriate skeleton which requires actions and guards is now
2338 * src/main.c (main): Adjust.
2339 * tests/semantic.at: New.
2340 * tests/regression.at: Use `input.y' as input file name.
2341 Avoid 8+3 problems by requiring input.c when the test needs the
2344 2001-12-27 Akim Demaille <akim@epita.fr>
2346 * src/reader.c (symbol_list_new): Be sure to initialize all the
2349 2001-12-27 Akim Demaille <akim@epita.fr>
2351 All the hacks using a final pseudo state are now useless.
2353 * src/LR0.c (set_state_table): state_table holds exactly nstates.
2354 * src/lalr.c (nLA): New.
2355 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
2356 instead of lookaheadsp from the pseudo state (nstate + 1).
2358 2001-12-27 Akim Demaille <akim@epita.fr>
2360 * src/output.c (action_row, token_actions): Use a state_t instead
2361 of a integer, and nlookaheads instead of the following state's
2364 2001-12-27 Akim Demaille <akim@epita.fr>
2366 * src/conflicts.c (log_resolution, flush_shift)
2367 (resolve_sr_conflict, set_conflicts, solve_conflicts)
2368 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
2369 (conflicts_print, print_reductions): Use a state_t instead of an
2370 integer when referring to a state.
2371 As much as possible, depend upon nlookaheads, instead of the
2372 `lookaheadsp' member of the following state (since lookaheads of
2373 successive states are successive, the difference between state n + 1
2374 and n served as the number of lookaheads for state n).
2375 * src/lalr.c (add_lookback_edge): Likewise.
2376 * src/print.c (print_core, print_actions, print_state)
2377 (print_results): Likewise.

2380 * src/conflicts.h: Adjust.
2382 2001-12-27 Akim Demaille <akim@epita.fr>
2384 * src/bison.hairy: Formatting/comment changes.
2386 Remove `register' indications.
2387 Add plenty of `static'.
2389 2001-12-27 Akim Demaille <akim@epita.fr>
2391 * src/output.c (prepare): Drop the muscle `ntbase' which
2393 * src/bison.simple: Formatting/comment changes.
2394 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
2395 is an undocumented synonym.
2397 2001-12-22 Akim Demaille <akim@epita.fr>
2399 * src/output.c (output_table_data): Change the prototype to use
2400 `int' for array ranges: some invocations do pass an int, not a
2402 Reported by Wayne Green.
2404 2001-12-22 Akim Demaille <akim@epita.fr>
2406 Some actions of web2c.y are improperly triggered.
2407 Reported by Mike Castle.
2409 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
2410 * tests/regression.at (Web2c): Rename as...
2411 (Web2c Report): this.
2412 (Web2c Actions): New.
2414 2001-12-22 Akim Demaille <akim@epita.fr>
2416 Reductions in web2c.y are improperly reported.
2417 Reported by Mike Castle.
2419 * src/conflicts.c (print_reductions): Fix.
2420 * tests/regression.at (Web2c): New.
2422 2001-12-18 Akim Demaille <akim@epita.fr>
2424 Some host fail on `assert (!"foo")', which expands to
2425 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
2426 Reported by Nelson Beebee.
2428 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
2429 `#define it_succeeded 0' and `assert (it_succeeded)'.
2431 2001-12-17 Marc Autret <autret_m@epita.fr>
2433 * src/bison.simple: Don't hard code the skeleton line and filename.
2434 * src/output.c (output_parser): Rename 'line' as 'output_line'.
2435 New line counter 'skeleton_line' (skeleton-line muscle).
2437 2001-12-17 Paul Eggert <eggert@twinsun.com>
2439 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
2440 YYDEBUG must be defined to a nonzero value.
2442 * src/bison.simple (yytname): Do not assume that the user defines
2443 YYDEBUG to a properly parenthesized expression.
2445 2001-12-17 Akim Demaille <akim@epita.fr>
2447 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
2448 nlookaheads is a new member.
2450 * src/lalr.h (nlookaheads): Remove this orphan declaration.
2451 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
2454 2001-12-17 Akim Demaille <akim@epita.fr>
2456 * src/files.h, src/files.c (open_files, close_files): Remove.
2457 * src/main.c (main): Don't open/close files, nor invoke lex_free,
2459 * src/reader.c (reader): Do it.
2461 2001-12-17 Akim Demaille <akim@epita.fr>
2463 * src/conflicts.c (print_reductions): Formatting changes.
2465 2001-12-17 Akim Demaille <akim@epita.fr>
2467 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
2468 (flush_reduce): New.
2469 (resolve_sr_conflict): Adjust.
2471 2001-12-17 Akim Demaille <akim@epita.fr>
2473 * src/output.c (output_obstack): Be static and rename as...
2474 (format_obstack): this, to avoid any confusion with files.c's
2476 * src/reader.h (muscle_obstack): Move to...
2477 * src/output.h: here, since it's defined in output.c.
2479 2001-12-17 Akim Demaille <akim@epita.fr>
2481 * src/output.c (action_row, save_column, default_goto)
2482 (sort_actions, matching_state, pack_vector): Better variable
2485 2001-12-17 Akim Demaille <akim@epita.fr>
2487 * src/output.c: Various formatting changes.
2489 2001-12-17 Akim Demaille <akim@epita.fr>
2491 * src/files.c (output_files): Free the output_obstack.
2492 * src/main.c (main): Call print and print_graph conditionally.
2493 * src/print.c (print): Work unconditionally.
2494 * src/print_graph.c (print_graph): Work unconditionally.
2495 * src/conflicts.c (log_resolution): Output only if verbose_flag.
2497 2001-12-16 Marc Autret <autret_m@epita.fr>
2499 * src/output.c (actions_output): Fix. When we use %no-lines,
2500 there is one less line per action.
2502 2001-12-16 Marc Autret <autret_m@epita.fr>
2504 * src/bison.simple: Remove a useless #line directive.
2505 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
2506 * src/output.c (get_lines_number): New.
2507 (output_parser): Adjust, now takes care about the lines of a
2510 (actions_output): Computes the number of lines taken by actions.
2511 (output_master_parser): Insert new skeleton which is the name of
2512 the output parser file name.
2514 2001-12-15 Marc Autret <autret_m@epita.fr>
2516 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
2518 2001-12-15 Marc Autret <autret_m@epita.fr>
2520 * src/output.c (output_gram): Keep track of the hairy one.
2522 2001-12-15 Akim Demaille <akim@epita.fr>
2524 Make `make distcheck' work.
2526 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
2527 system.h which uses libgettext.h.
2529 2001-12-15 Akim Demaille <akim@epita.fr>
2531 * src/nullable.c (set_nullable): Useless rules must be skipped,
2532 otherwise, since we range over their symbols, we might look at a
2533 nonterminal which no longer ``exists'', i.e., it is not counted in
2534 `nvars', hence we overflow our arrays.
2536 2001-12-15 Akim Demaille <akim@epita.fr>
2538 The header can also be produced directly, without any obstack!
2541 * src/files.c, src/files.h (defines_obstack): Remove.
2542 (compute_header_macro): Global.
2543 (defines_obstack_save): Remove.
2544 * src/reader.c (parse_union_decl): No longer output to
2545 defines_obstack: its content can be found in the `stype' muscle
2547 (output_token_translations): Merge into...
2548 (symbols_output): this.
2550 (symbols_save): this.
2552 * src/output.c (header_output): New.
2555 2001-12-15 Akim Demaille <akim@epita.fr>
2557 * src/reader.c (parse_union_decl): Instead of handling two obstack
2558 simultaneously, use one to define the `stype' muscle, and use the
2559 value of the latter to fill defines_obstack.
2560 (copy_comment): Remove.
2561 (copy_comment2): Work for a single obstack.
2563 (copy_comment): this.
2565 2001-12-15 Akim Demaille <akim@epita.fr>
2567 * src/lex.c, src/lex.h (xgetc): No longer static.
2568 * src/reader.c (parse_union_decl): Revamp.
2570 2001-12-15 Akim Demaille <akim@epita.fr>
2572 Still making progress in separating Bison into (i) input, (ii)
2573 process, (iii) output: now we can directly output the parser file
2574 without using table_obstack at all.
2576 * src/files.c, src/files.h (table_obstack): Bye bye.
2577 (parser_file_name): New.
2578 * src/files.c (compute_output_file_names): Compute it.
2579 * src/output.c (actions_output, output_parser)
2580 (output_master_parser): To a file instead of an obstack.
2582 2001-12-15 Akim Demaille <akim@epita.fr>
2584 Attach actions to rules, instead of pre-outputting them to
2587 * src/gram.h (rule_t): action and action_line are new members.
2588 * src/reader.c (symbol_list): Likewise.
2589 (copy_action): Save the actions within the rule.
2590 (packgram): Save them in rule_table.
2591 * src/output.c (actions_output): New.
2592 (output_parser): Use it on `%%actions'.
2593 (output_rule_data): Don't free rule_table.
2595 (prepare): Don't save the `action' muscle.
2596 * src/bison.simple: s/%%action/%%actions/.
2598 2001-12-15 Akim Demaille <akim@epita.fr>
2600 * src/reader.c (copy_action): When --yacc, don't append a `;'
2601 to the user action: let it fail if lacking.
2602 Suggested by Arnold Robbins and Tom Tromey.
2604 2001-12-14 Akim Demaille <akim@epita.fr>
2606 * src/lex.c (literalchar): Simply return the char you decoded, non
2607 longer mess around with obstacks and int pointers.
2610 2001-12-14 Akim Demaille <akim@epita.fr>
2612 * src/lex.c (literalchar): Don't escape the special characters,
2613 just decode them, and keep them as char (before, eol was output as
2614 the 2 char string `\n' etc.).
2615 * src/output.c (output_rule_data): Use quotearg to output the
2618 2001-12-13 Paul Eggert <eggert@twinsun.com>
2620 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
2621 Do not infringe on the global user namespace when using C++.
2622 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
2623 All uses of `fprintf' and `stderr' changed.
2625 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
2627 2001-12-13 Akim Demaille <akim@epita.fr>
2629 The computation of nullable is broken: it doesn't handle empty
2632 * tests/torture.at (GNU AWK Grammar): New.
2633 * tests/sets.at (Nullable): New.
2634 * src/nullable.c (set_nullable): Instead of blindly looping over
2635 `ritems', loop over the rules, and then over their rhs's.
2637 Work around Autotest bugs.
2639 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
2640 frame, because Autotest understand lines starting with a `+' as
2641 traces from the shell. Then, they are not processed properly.
2642 Admittedly an Autotest bug, but we don't have time to wait for
2643 Autotest to catch up.
2644 * tests/regression.at (Broken Closure): Adjust to the new table
2647 * tests/sets.at: here.
2649 2001-12-13 Akim Demaille <akim@epita.fr>
2651 * src/closure.c (closure): Use nrules instead of playing tricks
2654 2001-12-13 Akim Demaille <akim@epita.fr>
2656 * src/print.c (print_actions): Output the handling of `$' as the
2657 traces do: shifting the token EOF. Before EOF was treated as a
2659 * tests/regression.at: Adjust some tests.
2660 * src/print_graph.c (print_core): Complete the set of items via
2661 closure. The next-to-final and final states are still unsatisfying,
2662 but that's to be addressed elsewhere.
2663 No longer output the rule numbers, but do output the state number.
2664 A single loop for the shifts + gotos is enough, but picked a
2665 distinct color for each.
2666 (print_graph): Initialize and finalize closure.
2668 2001-12-13 Akim Demaille <akim@epita.fr>
2670 * src/reader.c (readgram): Remove dead code, an strip useless
2672 (get_type): Remove, unused.
2674 2001-12-12 Akim Demaille <akim@epita.fr>
2676 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
2677 on that of lib/error.c.
2679 2001-12-12 Akim Demaille <akim@epita.fr>
2681 Some hosts don't like `/' in includes.
2683 * src/system.h: Include libgettext.h without qualifying the path.
2684 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
2687 2001-12-11 Marc Autret <autret_m@epita.fr>
2689 * src/output.c (output_parser): Remove useless muscle.
2691 2001-12-11 Marc Autret <autret_m@epita.fr>
2693 * src/bison.simple: Remove #line just before %%epilogue. It
2694 is now handled in ...
2695 * src/reader.c (read_additionnal_code): Add the output of a
2696 #line for the epilogue.
2698 2001-12-10 Marc Autret <autret_m@epita.fr>
2700 * src/reader.c (copy_definition): Re-use CPP-outed code which
2701 replace precedent remove.
2702 * src/bison.simple: Remove #line before %%prologue because
2703 %%input-line is wrong at this time.
2705 2001-12-10 Marc Autret <autret_m@epita.fr>
2707 * src/reader.c (symbols_output): Clean up.
2708 * src/output.c (output_gram, output): Clean up.
2710 2001-12-10 Akim Demaille <akim@epita.fr>
2712 * src/lalr.c (initialize_lookaheads): New. Extracted from...
2713 * src/LR0.c (set_state_table): here.
2714 * src/lalr.c (lalr): Call it.
2716 2001-12-10 Akim Demaille <akim@epita.fr>
2718 * src/state.h (shifts): Remove the `number' member: shifts are
2719 attached to state, hence no longer need to be labelled with a
2722 2001-12-10 Akim Demaille <akim@epita.fr>
2724 Now that states have a complete set of members, the linked list of
2725 shifts is useless: just fill directly the state's shifts member.
2727 * src/state.h (shifts): Remove the `next' member.
2728 * src/LR0.c (first_state, last_state): Remove.
2730 (augment_automaton): Don't look for the shifts that must be added
2731 a shift on EOF: it is those of the state we looked for! But now,
2732 since shifts are attached, it is no longer needed to looking
2733 merely by its id: its number.
2735 2001-12-10 Akim Demaille <akim@epita.fr>
2737 * src/LR0.c (augment_automaton): Better variable locality.
2738 Remove an impossible branch: if there is a state corresponding to
2739 the start symbol being shifted, then there is shift for the start
2740 symbol from the initial state.
2742 2001-12-10 Akim Demaille <akim@epita.fr>
2744 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
2745 only when appropriate: when insert_start_shifting_state' is not
2747 * tests/regression.at (Rule Line Numbers): Adjust.
2749 2001-12-10 Akim Demaille <akim@epita.fr>
2751 * src/LR0.c (augment_automaton): Now that all states have shifts,
2752 merge the two cases addition shifts to the initial state.
2754 2001-12-10 Akim Demaille <akim@epita.fr>
2756 * src/lalr.c (set_state_table): Move to...
2758 * src/lalr.c (lalr): Don't call it...
2759 * src/LR0.c (generate_states): do it.
2760 * src/LR0.h (first_state): Remove, only the table is used.
2762 2001-12-10 Akim Demaille <akim@epita.fr>
2764 * src/LR0.h (first_shift, first_reduction): Remove.
2765 * src/lalr.c: Don't use first_shift: find shifts through the
2768 2001-12-10 Akim Demaille <akim@epita.fr>
2770 * src/LR0.c: Attach shifts to states as soon as they are
2772 * src/lalr.c (set_state_table): Instead of assigning shifts to
2773 state, just assert that the mapping was properly done.
2775 2001-12-10 Akim Demaille <akim@epita.fr>
2777 * src/LR0.c (insert_start_shift): Rename as...
2778 (insert_start_shifting_state): this.
2779 (insert_eof_shifting_state, insert_accepting_state): New.
2780 (augment_automaton): Adjust.
2781 Better locality of the variables.
2782 When looking if the start_symbol is shifted from the initial
2783 state, using `while (... symbol != start_symbol ...)' sounds
2784 better than `while (... symbol < start_symbol ...)': If fail
2785 to see how the order between symbols could be relevant!
2787 2001-12-10 Akim Demaille <akim@epita.fr>
2789 * src/getargs.h: Don't declare `spec_name_prefix' and
2790 `spec_file_prefix', declared by src/files.h.
2791 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
2792 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
2793 * src/output.c (prepare): Adjust.
2794 * src/reader.c (symbols_output): Likewise.
2795 * src/vmsgetargs.c: Vaguely adjust, but who cares?
2797 2001-12-10 Akim Demaille <akim@epita.fr>
2799 * src/muscle_tab.c (muscle_init): NULL is a better default than
2802 2001-12-10 Akim Demaille <akim@epita.fr>
2804 * src/reader.c (reader): Calling symbols_output once is enough.
2806 2001-12-10 Akim Demaille <akim@epita.fr>
2808 Now that states have a complete set of members, the linked list of
2809 reductions is useless: just fill directly the state's reductions
2812 * src/state.h (struct reductions): Remove member `number' and
2814 * src/LR0.c (first_reduction, last_reduction): Remove.
2815 (save_reductions): Don't link the new reductions, store them in
2817 * src/lalr.c (set_state_table): No need to attach reductions to
2818 states, it's already done.
2819 * src/output.c (output_actions): No longer free the shifts, then
2820 the reductions, then the states: free all the states and their
2823 2001-12-10 Akim Demaille <akim@epita.fr>
2825 * src/options.c (OPTN, DRTV, BOTH): New.
2826 (option_table): Use them.
2828 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
2829 the job of system.h.
2830 * src/options.c: Don't include stdio.h and xalloc.h for the same
2833 2001-12-10 Akim Demaille <akim@epita.fr>
2835 * src/output.c (output, prepare): Make sure the values of the
2836 muscles `action' and `prologue' are 0-terminated.
2838 2001-12-10 Akim Demaille <akim@epita.fr>
2840 Clean up GCC warnings.
2842 * src/reader.c (copy_action): `buf' is not used.
2843 (parse_skel_decl): Be static.
2844 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
2845 * src/options.h (create_long_option_table): Have a real prototype.
2846 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
2847 (hash_delete_at): Return const void *.
2848 Adjust casts to preserve the const.
2850 2001-12-10 Akim Demaille <akim@epita.fr>
2852 * configure.in: Require 2.52g.
2853 M4 is not needed, but AUTOM4TE is.
2855 * tests/Makefile.am: Adjust.
2857 2001-12-10 Akim Demaille <akim@epita.fr>
2859 One structure for states is enough, even though theoretically
2860 there are LR(0) states and LALR(1) states.
2862 * src/lalr.h (state_t): Remove.
2863 (state_table): Be state_t **, not state_t *.
2864 * src/state.h (core, CORE_ALLOC): Rename as...
2865 (state_t, STATE_ALLOC): this.
2866 Add the LALR(1) members: shifts, reductions, errs.
2867 * src/LR0.c (state_table): Rename as...
2868 (state_hash): this, to avoid name clashes with the global
2870 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
2871 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
2873 2001-12-10 Akim Demaille <akim@epita.fr>
2875 Bison dumps core on bash.y.
2876 Reported by Pascal Bart.
2878 * src/warshall.c (bitmatrix_print): New.
2880 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
2881 j must be the outer loop.
2882 * tests/regression.at (Broken Closure): New.
2884 2001-12-05 Akim Demaille <akim@epita.fr>
2886 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
2888 Reported by Peter Hámorský.

2892 * src/conflicts.c (err_table): Remove.
2893 (resolve_sr_conflict): Adjust.
2894 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
2896 (state_t.reductions, state_t.shifts): this.
2898 2001-12-05 Akim Demaille <akim@epita.fr>
2900 * src/reduce.c (reduce_grammar_tables): No longer disable the
2901 removal of useless rules via CPP but via `if (0)', so that the
2902 compiler still check the code is valid.
2903 For instance, it should have noticed `rline' no longer exists: use
2904 the `line' member of rule_t.
2905 * src/gram.c (dummy, rline): Remove, unused.
2907 2001-12-05 Akim Demaille <akim@epita.fr>
2909 * src/output.c (pack_vector): Use assert, not berror.
2910 * src/main.c (berror): Remove, unused.
2912 2001-12-05 Akim Demaille <akim@epita.fr>
2914 New experimental feature: if --verbose --trace output all the
2915 items of a state, not only its kernel.
2917 * src/print.c (print_core): If `trace_flag', then invoke closure
2918 before outputting the items of the state (print_core is no longer
2919 a correct name them).
2920 (print_results): Invoke new_closure/free_closure if needed.
2922 2001-12-05 Akim Demaille <akim@epita.fr>
2924 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
2925 * src/closure.c, src/closure.h (itemsetsize): Rename as...
2926 (nitemset): for consistency with the rest of the project.
2928 2001-12-05 Akim Demaille <akim@epita.fr>

2931 (closure): Use it for printing input and output.
2933 2001-12-05 Akim Demaille <akim@epita.fr>
2935 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
2936 indexed by nonterminals.
2938 2001-12-05 Akim Demaille <akim@epita.fr>
2940 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

2960 locality, BITISSET, RESETBIT etc.
2962 2001-12-05 Akim Demaille <akim@epita.fr>
2964 Pessimize the code to simplify it: from now on, all the states
2965 have a valid SHIFTS, which NSHIFTS is possibly 0.
2967 * src/LR0.c (shifts_new): Be global and move to..
2968 * src/state.c, src/state.h: here.
2969 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

2974 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
2975 * src/conflicts.c: Use it.
2976 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
2977 incorrectly ``simplified''.
2979 2001-12-05 Akim Demaille <akim@epita.fr>
2981 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
2982 using the good o' techniques: arrays not pointers, variable

2987 * src/state.h (SHIFT_SYMBOL): New.

2992 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
2993 (print_reductions): De-obfuscate using the good o' techniques:

3037 * src/lalr.c (build_relations): Adjust.
3039 2001-12-05 Akim Demaille <akim@epita.fr>
3041 * src/lalr.c (transpose): Free the memory allocated to the
3042 argument, as it is replaced by the results by the unique caller.
3043 (build_relations): Merely invoke transpose: it handles the memory
3045 Improve variable locality.
3046 Avoid variables used as mere abbreviations.
3047 (compute_lookaheads): Use arrays instead of pointers.
3049 2001-12-05 Akim Demaille <akim@epita.fr>

3067 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
3068 the handling of squeue.
3069 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3071 2001-12-05 Akim Demaille <akim@epita.fr>
3073 Because useless nonterminals are now kept alive (instead of being
3074 `destroyed'), we now sometimes examine them, and store information
3075 related to them. Hence we need to know their number, and adjust
3078 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
3080 * src/LR0.c (allocate_itemsets): The memory allocated to
3081 `symbol_count' was used for two different purpose: once to count
3082 the number of occurrences of each symbol, and later reassigned to
3083 `shift_symbol', containing the symbol that can be shifted from a
3085 Deobfuscate, i.e., allocate, use and free `symbol_count' here
3087 (new_itemsets): Allocate `shift_symbol' here.
3088 (allocate_itemsets): symbol_count includes useless nonterminals.
3090 (free_storage): Use `free', not `XFREE', for pointers that cannot
3093 2001-12-05 Akim Demaille <akim@epita.fr>
3095 * src/nullable.c (set_nullable): Deobfuscate the handling of
3097 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.

3101 * src/gram.c, src/gram.h (ritem_print): New.
3102 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
3103 (This useless function was defined only to work around VMS linkers
3104 that can't handle compilation units with variables only).
3105 * src/reduce.c (dump_grammar): Use it to trace the construction of
3108 2001-12-04 Paul Eggert <eggert@twinsun.com>
3110 * src/bison.simple (union yyalloc): Change member names
3111 to be the same as the stack names.
3112 (yyparse): yyptr is now union yyalloc *, not char *.
3113 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
3114 and may generate better code on some machines.
3115 (yystpcpy): Use prototype if __STDC__ is defined, not just
3116 if __cplusplus is defined.
3118 2001-11-30 Akim Demaille <akim@epita.fr>
3120 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
3121 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU

3123 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
3124 Include WARNING_CFLAGS here.
3125 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

3130 * lib/quotearg.h (quotearg_n, quotearg_n_style):
3131 First arg is int, not unsigned.
3132 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
3133 (SIZE_MAX, UINT_MAX): New macros.
3134 (quotearg_n_options): Abort if N is negative.
3135 Avoid overflow check on hosts where size_t is 64 bits and int
3136 is 32 bits, as overflow is impossible there.
3137 Fix off-by-one typo that caused unnecessary reallocation.
3139 2001-11-29 Paul Eggert <eggert@twinsun.com>
3141 Name space cleanup in generated parser.
3143 * doc/bison.texinfo (Bison Parser): Discuss system headers
3144 and their effect on the user name space.
3147 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
3148 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
3149 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
3151 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
3152 on user names when possible.
3154 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
3155 Simplify test for whather <alloca.h> exists.
3157 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
3159 (<stdio.h>): Include if YYDEBUG.
3161 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
3162 ! defined (yyoverflow) && ! defined (yymemcpy).
3164 (yymemcpy, yyparse): Rename local variables as needed so that
3165 they all begin with 'yy'.
3167 (yystrlen, yystpcpy): New functions.
3169 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
3172 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
3173 instead of relying on string.h functions. Use YYSTACK_ALLOC
3174 and YYSTACK_FREE instead of malloc and free.
3176 2001-11-30 Akim Demaille <akim@epita.fr>
3178 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
3179 before their first uses.

3188 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
3189 if body instead of `;' to pacify GCC's warnings.
3191 2001-11-30 Akim Demaille <akim@epita.fr>
3193 Instead of mapping the LHS of unused rules to -1, keep the LHS
3194 valid, but flag the rules as invalid.
3196 * src/gram.h (rule_t): `useful' is a new member.
3197 * src/print.c (print_grammar): Adjust.
3198 * src/derives.c (set_derives): Likewise.
3199 * src/reader.c (packgram, reduce_output): Likewise.

3213 useless nonterminals, move them at the end of the symbol arrays.
3214 (reduce_output): Adjust.

3227 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
3228 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
3230 (union yyalloc): New type.
3231 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
3232 an arbitrary restriction on hosts where size_t is wider than int.
3234 (yyparse): Don't dump core if alloca or malloc fails; instead, report
3235 a parser stack overflow. Allocate just one block of memory for all
3236 three stacks, instead of allocating three blocks; this typically is
3237 faster and reduces fragmentation.
3239 Do not limit the number of items in the stack to a value that fits
3240 in 'int', as this is an arbitrary limit on hosts with 64-bit
3241 size_t and 32-bit int.

5399 2000-10-16 Akim Demaille <akim@epita.fr>
5401 * src/reader.c (copy_comment2): Expect the input stream to be on
5402 the `/' which is suspected to open a comment, instead of being
5403 called after `//' or `/*' was read.
5404 (copy_comment, copy_definition, parse_union_decl, copy_action)
5405 (copy_guard): Adjust.
5407 2000-10-16 Akim Demaille <akim@epita.fr>
5409 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

5419 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
5420 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
5421 New files, from Fileutils 4.0.27.
5422 * src/main.c (printable_version): Remove.
5423 * src/lex.c, src/reader.c: Use `quote'.
5425 2000-10-04 Akim Demaille <akim@epita.fr>
5427 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
5429 2000-10-04 Akim Demaille <akim@epita.fr>
5431 * doc/bison.texinfo: Various typos spotted by Neil Booth.
5433 2000-10-04 Akim Demaille <akim@epita.fr>
5435 When a literal string is used to define two different tokens,
5436 `bison -v' segfaults.
5437 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
5439 * tests/regression.m4: New file.
5440 Include the core of the sample provided by Piotr Gackiewicz.
5441 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
5444 2000-10-04 Akim Demaille <akim@epita.fr>
5446 * src/reader.c (parse_expect_decl): Keep `count' within the size
5450 2000-10-02 Paul Eggert <eggert@twinsun.com>

5458 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
5461 2000-10-02 Akim Demaille <akim@epita.fr>
5463 * src/derives.c, src/print.c, src/reduce.c: To ease the
5464 translation, move some `\n' out of the translated strings.
5466 2000-10-02 Akim Demaille <akim@epita.fr>
5468 The location tracking mechanism is precious for parse error
5469 messages. Nevertheless, it is enabled only when `@n' is used in
5470 the grammar, which is a different issue (you can use it in error
5471 message, but not in the grammar per se). Therefore, there should
5472 be another means to enable it.
5474 * src/getargs.c (getargs): Support `--locations'.
5476 * src/getargs.h (locationsflag): Export it.
5477 * src/lex.c (percent_table): Support `%locations'.
5478 * src/reader.c (yylsp_needed): Remove this variable, now replaced
5479 with `locationsflag'.
5480 * doc/bison.texinfo: Document `--locations' and `%locations'.
5482 * tests/calc.m4: Test it.
5484 For regularity of the names, replace each
5485 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
5486 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
5487 In addition replace each `flag' with `_flag'.
5489 2000-10-02 Akim Demaille <akim@epita.fr>
5491 Also test parse error messages, including with YYERROR_VERBOSE.
5493 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
5495 Use it to check the computations.
5496 Use it to check `nonassoc' is honored.
5497 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
5498 `--yyerror-verbose'.

5500 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
5502 2000-10-02 Akim Demaille <akim@epita.fr>
5504 Test also `--verbose', `--defines' and `--name-prefix'. Testing
5505 the latter demonstrates a flaw in the handling of non debugging
5506 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
5507 was used in order to simplify:
5523 unfortunately this leads to a CPP conflict when
5524 `--name-prefix=foo' is used since it produces `#define yydebug
5527 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
5528 (YYDPRINTF): New macro.
5530 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
5532 Also test `--verbose', `--defines' and `--name-prefix'.
5534 2000-10-02 Akim Demaille <akim@epita.fr>
5536 Improve the readability of the produced parsers.
5538 * src/bison.s1: Formatting changes.
5539 Improve the comment related to the `$' mark.
5540 (yydefault): Don't fall through to `yyresume': `goto' there.
5541 * src/output.c (output_parser): When the `$' is met, skip the end
5543 New variable, `number_of_dollar_signs', to check there's exactly
5544 one `$' in the parser skeleton.
5546 2000-10-02 Akim Demaille <akim@epita.fr>
5548 * lib/xstrdup.c: New file, from the fileutils.
5549 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
5550 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
5551 instead of strlen + xmalloc + strcpy.
5552 * src/symtab.c (copys): Remove, use xstrdup instead.
5554 2000-10-02 Akim Demaille <akim@epita.fr>
5556 * src/gram.h (associativity): New enum type which replaces the
5557 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
5558 `right_assoc', `left_assoc' and `non_assoc'.
5559 Adjust all dependencies.
5560 * src/reader.c: Formatting changes.
5561 (LTYPESTR): Don't define it, use it as a literal in
5562 `reader_output_yylsp'.
5563 * src/symtab.h (symbol_class): New enum type which replaces the
5564 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

5570 (yaccflag): for consistency and accuracy.
5571 Adjust dependencies.
5573 2000-10-02 Akim Demaille <akim@epita.fr>
5575 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
5576 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
5577 difficult and introduced a lot of core dump. It turns out that
5578 Bison used an implementation of `xmalloc' based on `calloc', and
5579 at various places it does depend upon the initialization to 0. I
5580 have not tried to isolate the pertinent places, and all the former
5581 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
5582 someone should address this issue.
5584 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
5585 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

5683 2000-10-02 Akim Demaille <akim@epita.fr>
5685 `user_toknums' is output as a `short[]' in `output.c', while it is
5686 defined as a `int[]' in `reader.c'. For consistency with the
5687 other output tables, `user_toknums' is now defined as a table of

5954 of the lhs of the rule (by default ranging from the location of
5955 the first symbol of the rhs, to the location of the last symbol,
5956 or, if the rhs is empty, YYLLOC).
5958 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
5960 (yyparse): When providing a default semantic action, provide a
5961 default location action.

6661 Revise error message.
6662 (print_notices): Remove final `.' from error message.
6664 * src/reader.c (reader_output_yylsp):
6666 (readgram): Use `#if 0' around code that accepted %command
6667 inside grammar rules: The documentation doesn't allow it,
6668 and it will fail since the %command processors scan for the next %.
6669 (parse_token_decl): Extended the %token
6670 declaration to allow a multi-character symbol as an alias.
6671 (parse_thong_decl): New function.
6672 (read_declarations): Added %thong declarations.
6673 (read_declarations): Handle NOOP to deal with allowing
6674 % declarations as another means to specify the flags.
6675 (readgram): Allow %prec prior to semantics embedded in a rule.
6676 (skip_to_char, read_declarations, copy_definition)
6677 (parse_token_decl, parse_start_decl, parse_type_decl)
6678 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
6679 (get_type_name, copy_guard, copy_action, readgram)
6680 (get_type, packsymbols): Revised most error messages.
6681 Changed `fatal' to `warnxxx' to avoid aborting for error.
6682 Revised and use multiple warnxxx functions to avoid using VARARGS1.
6683 (read_declarations): Improve the error message for
6684 an invalid character. Do not abort.
6685 (read_declarations, copy_guard, copy_action): Use
6686 printable_version to avoid unprintable characters in printed output.
6687 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
6688 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
6689 Allow the type of a non-terminal can be given
6690 more than once, as long as all specifications give the same type.
6693 (output_headers, output_trailers, output, output_gram)
6694 (output_rule_data): Implement noparserflag variable.
6695 Implement toknumflag variable.
6696 (output): Call reader_output_yylsp to output LTYPESTR.
6698 * src/main.c (main):
6699 If reader sees an error, don't process the grammar.
6700 (fatals): Updated to not use VARARGS1.
6701 (printable_version, int_to_string, warn, warni, warns, warnss)
6702 (warnsss): New error reporting functions. Avoid abort for error.
6705 Added THONG and NOOP for alias processing.
6706 Added SETOPT for the new code that allows setting options with %flags.
6709 Include getopt.h. Add some extern decls.
6710 (safegetc): New function to deal with EOF gracefully.
6711 (literalchar); new function to deal with reading \ escapes.
6712 (lex): Use literalchar.
6713 (lex): Implemented "..." tokens.
6714 (literalchar, lex, parse_percent_token): Made tokenbuffer
6715 always contain the token. This includes growing the token
6716 buffer while reading an integer.
6717 (parse_percent_token): Replaced if-else statement with percent_table.
6718 (parse_percent_token): Added % declarations as another
6719 way to specify the flags -n, -l, and -r. Also added hooks for
6720 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
6721 major changes to files.c.
6722 (lex) Retain in the incoming stream a character following
6724 (skip_white_space, lex): Revised most error messages
6725 and changed fatal to warn to avoid aborting.
6726 (percent_table): Added %thong declarations.
6728 * src/gram.h: Comment changes.
6730 * src/files.c (openfiles, open_extra_files, done):
6732 and actfile file. Handle noparserflag. Both for -n switch.
