483 Always put auxiliary code files in the same dir as other output files.
484 * src/files.c (compute_file_name_parts): When the user specifies
485 --output but not --file-prefix, extract the directory prefix from the
486 file prefix not from the grammar file name. This affects the location
487 of files like location.hh generated by the C++ skeleton. The includes
488 in the other output files require this fix.
489 * tests/output.at (AT_CHECK_OUTPUT): Automatically create directories
490 for expected output files.
491 (Output files): Add a test for the above.
492
493 2008-10-29 Joel E. Denny <jdenny@ces.clemson.edu>

601 expected.
602
603 2008-08-27 Akim Demaille <demaille@gostai.com>
604

668 Partial m4sugar merge from autoconf: builtins, version.m4.
669 * data/m4sugar/m4sugar.m4 (changeword): Nuke.

723
724 Fix dependence on computed configure variables.
725 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
726 $(top_srcdir)/configure.ac so that changes to computed variables, such
727 as PACKAGE_VERSION, are seen.

751 .prev-version, and .version.
752 * NEWS (2.3b+): Rename to...
753 (?.?): ... this because we're dropping the "+" version naming scheme,
754 but, in general, we still can't be sure of our next release name.
755 * bootstrap: Add a quick hack to remove from .gitignore the
756 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
757 entry. This should really be fixed in gnulib instead.
758 * bootstrap.conf (gnulib_modules): Add gnumakefile.
759 * configure.ac (AC_INIT): Set version name by invoking
760 build-aux/git-version-gen.

787
788 2008-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
789
790 Fix some .gitignore and .cvsignore problems.
791 * bootstrap (insert_sorted_if_absent): Replace all uses with...
792 (insert_vc_ignore): ... this new function, which prepends `/' to all
793 .gitignore entries before passing them to insert_sorted_if_absent.
794 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
795 .cvsignore files are maintained even though Bison developers run
796 bootstrap while using Git.
797 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
798 unneeded by Bison.
799 (gnulib): Add.
800 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
801 unneeded. Reported by Eric Blake.
802 * lib/.gitignore (/*~): Add.
803 * po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore.
804 * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric
805 Blake.
806 * src/.gitignore (/bison.exe): Add. Reported by Eric Blake.
807

810 Improve forward-compatibility with GNU M4. Reported by Eric Blake at

814 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
815 (/setenv.m4): Add.
816 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
817 the first argument because it may become position-dependent, and unset
818 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
819 Add comments explaining these issues in more detail.
820
821 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

857 been doing it for years.
858 (Test suite): Mention maintainer-push-check and maintainer-xml-check.
859 (Release Procedure): Add FIXME about make alpha being unmaintained.
860

878
879 * THANKS: Add Eric Blake.
880
881 2008-04-23 Eric Blake <ebb9@byu.net>
882
883 Revert prior patch, by working around autoconf regression.
884 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
885 ("Output file name: ("): Uncomment test.
886 ("Output file name: )"): Likewise.
887 Based on an idea from Noah Misch.
888
889 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
890
891 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
892 2.61. Reported by Juan Manuel Guerrero at
893 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
894 * tests/output.at ("Output file name: ("): Comment out test case for
895 now.
896 ("Output file name: )"): Likewise.
897
898 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
899
900 * GNUmakefile: Update git-version-gen invocation so make dist
901 succeeds.
902
903 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
904
905 Update to the current gnulib CVS repository, and fix trigraph handling
906 in Bison.
907 * bootstrap: Update gnulib CVS repository URL.
908 (symlink_to_dir): Encapsulate the code that guarantees the destination
909 directory exists into...
910 (check_dst_dir): ... this new function, and...
911 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
912 fail when copying files into lib/uniwidth/.
913 * src/output.c (prepare_symbols): When writing yytname muscles, where
914 symbol names will be encoded in C-string literals, tell quotearg to
915 escape trigraphs. This used to be the default in gnulib.
916 * tests/regression.at (Token definitions): Because of the change in
917 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
918 escapes trigraphs in symbol names. Thus, yytname no longer has
919 trigraphs unnecessarily doubly escaped. Update test case output.
920 Extend test case to be sure Bison's own error messages will no longer
921 have trigraphs in symbol names unnecessarily escaped once.
922
923 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>
924
925 Fix make dist infinite loop reported by Juan Manuel Guerrero at

934
935 * NEWS (2.3a+): Mention that -g now takes an argument.

1449
1450 For the XML output's terminal element, rename @number to @token-number,
1451 and add @symbol-number. In the nonterminal element, rename @number to
1452 @symbol-number. Discussed starting at
1453 <http://lists.gnu.org/archive/html/bison-patches/2007-10/msg00040.html>.

1462
1463 * data/xslt/xml2dot.xsl (xsl:template match="automaton/state"): After

1467 (xsl:template match="point"): Remove.
1468 (xsl:template match="empty"): For consistency with --graph, don't
1469 output "/* empty */".

1471 line-wrap, don't pass a negative value as first-line-length since this
1472 won't work with the following changes.
1473 (xsl:template name="line-wrap"): Simplify slightly.
1474 (xsl:template name="ws-search"): Eliminate recursion.
1475 * src/print_graph.c (print_core): Don't print a reduction's lookahead

1537
1538 Make xml2dot.xsl and --graph produce the same output.
1539 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a `&#10;'
1540 instead of a `\n'. That is, don't add escapes yet or they'll be doubly
1541 escaped later.

1546 addition to quotation marks.
1547 * src/graphviz.c (start_graph, output_node, output_edge): Add
1548 whitespace to output for legibility.
1549
1550 Make xml2text.xsl and --report produce the same output, and remove the
1551 XML "conflicts" element since a conflict summary is easily extracted
1552 from the automaton.
1553 * data/xslt/bison.xsl: New.
1554 (xsl:template match="state" mode="bison:count-conflicts): New.
1555 * data/xslt/xml2text.xsl: Import bison.xsl.
1556 (xsl:template match="bison-xml-report"): Instead of styling the
1557 "conflicts" element, style the "automaton" element with mode

1559 conflicts for a state on the same line.
1560 (xsl:template match="conflicts"): Remove.
1561 (xsl:template match="conflict"): Remove.
1562 (xsl:template match="terminal"): Line-wrap the list of rules in which

1578 * src/conflicts.h (conflicts_output_xml): Remove prototype.
1579 * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml.
1580 * src/print.c (print_grammar): Consistently wrap at the 66th column so
1581 the corresponding XSLT is easier. Also, never wrap between a word and
1582 the comma that follows it.
1583
1584 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>
1585
1586 Improve C++ namespace support. Discussed starting at
1587 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
1588 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
1589 b4_namespace_close): New macros that interpret the %define variable
1590 "namespace" so its value can contain "::" to indicate nested
1591 namespaces.
1592 * data/glr.cc (b4_namespace): Don't define, and replace all uses with
1593 the above macros.
1594 * data/lalr1.cc (b4_namespace): Likewise.
1595 * data/location.cc (b4_namespace): Likewise.
1596 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
1597 inside a new table in the general %define entry. Document `%define
1598 namespace' there as well. Point the %name-prefix entry to it since it
1599 explains it more completely in the case of C++.
1600 (C++ Bison Interface): Mention `%define namespace' instead of
1601 %name-prefix.
1602 (Table of Symbols): Remove the `%define push_pull' entry. The %define
1603 entry suffices.
1604 * tests/c++.at (Relative namespace references): New test case.
1605 (Absolute namespace references): New test case.
1606 (Syntactically invalid namespace references): New test case.
1607 * tests/input.at (C++ namespace reference errors): New test case.

1615 (b4_percent_define_flag_if): Use b4_percent_define_get_loc.
1616 (b4_percent_define_default): Record defining location as line 1 rather
1617 than 0 for the sake of synchronizing #line's, and define
1618 b4_percent_define_syncline(VARIABLE).
1619 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
1620 * src/muscle_tab.c (muscle_syncline_grow): New.
1621 (muscle_code_grow): Use muscle_syncline_grow.
1622 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and

1626 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
1627 remove some unused variables.
1628 (muscle_percent_define_default): Record defining location as line 1
1629 rather than 0 for the sake of synchronizing #line's, and define
1630 b4_percent_define_syncline(VARIABLE).
1631 (muscle_percent_define_check_values): Use
1632 muscle_percent_define_get_loc.
1633 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.

1639
1640 2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
1641
1642 Fix some error-reporting macro bugs.
1643 * data/bison.m4 (b4_cat): New.
1644 (b4_error, b4_error_at): Use b4_cat to send error directives directly
1645 to stdout so they don't become arguments to other macros. Update
1646 comments and add examples.
1647 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
1648 add examples.
1649 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
1650 after printing the error directive so that M4 doesn't report subsequent
1651 problems that are induced by this problem.
1652 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
1653 instead of just in them. Recognize @\n in both places. Both expand to
1654 the empty string. Needed by b4_cat.
1655 * tests/skeletons.at (Complaining during macro argument expansion):
1656 New test case.
1657 (Fatal errors make M4 exit immediately): New test case.
1658

1670 * src/output.h (compute_pkgdatadir): Prototype.
1671
1672 2007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>
1673
1674 * src/print-xml.c (escape_bufs): New static global variable

1686 Pull Parser Function, Parser Create Function, Parser Delete Function):
1687 Update declarations.
1688 (Decl Summary, Table of Symbols): Replace %push-parser and

1692 definitions...
1693 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
1694 definitions...
1695 * data/push.c: ... to here and compute them from the value of the
1696 %define variable push_pull.
1697 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
1698 parsing requests here...
1699 * data/yacc.c: ... hack this to switch to push.c any time
1700 b4_use_push_pull_flag or the %define variable push_pull is set. This
1701 will go away when we mv push.c yacc.c.
1702 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
1703 push parsing is not supported since unused %define variables are
1704 reported anyway.
1705 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.

1742
1743 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
1744

1750
1751 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
1752
1753 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
1754 elsewhere.
1755 * src/print-xml.c: Prefer "const" after types; that's more consistent.
1756 (xml_printf): Indent just 1 space for level.
1757 (e_char, xlate_char): Remove.

1829 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
1830
1831 In impure push mode, don't allow more than one yypstate to be allocated
1832 since multiple impure parsers would corrupt yynerrs.
1833 * data/push.c (yypstate_allocated): New static global variable
1834 initialized to 0.
1835 (yypull_parse): If yypstate_new returns 0, don't report it as memory
1836 exhaustion if yypstate_allocated is 1, but still return 2.
1837 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
1838 already 1. Otherwise, set it to 1.

1912 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
1913
1914 Get rid of broken %no-parser, -n, and --no-parser implementation and
1915 documentation.
1916 * TODO: Don't mention them.
1917 * doc/bison.1: Likewise.
1918 * doc/bison.texinfo (Decl Summary): Likewise.
1919 (Bison Options): Likewise.
1920 (Option Cross Key): Likewise.
1921 * src/getargs.c (no_parser_flag): Remove global variable.
1922 (usage): Don't print description of -n and --no-parser.
1923 (long_options): Remove --no-parser entry here.
1924 (getargs): Remove -n case in the switch here.
1925 * src/getargs.h (no_parser_flag): Remove extern.
1926 * tests/regression.at (Web2c Actions): Remove comment that mentions
1927 --no-parser.
1928
1929 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
1930
1931 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
1932 name user variables starting with `yy'. Just pass NULL instead of a
1933 dummy local &yylval to yypush_parse.
1934 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
1935 starting with `yy'.
1936
1937 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
1938
1939 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
1940 true since it's then always used regardless of whether yyoverflow is
1941 defined. Reported by Christian Burger at
1942 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
1943 * THANKS: Add Christian Burger.
1944
1945 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1946 node names: say "Decl Summary" not "Bison Declaration Summary".
1947
1948 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
1949
1950 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
1951 determine whether this function has already complained about an invalid
1952 value for a %define boolean variable, don't check whether Bison has
1953 ever examined the value. As written, the check was a tautology.
1954 Instead, record and check for this complaint using a separate muscle.
1955
1956 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
1957
1958 Fix push parsing memory leak reported by Brandon Lucia at
1959 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
1960 * THANKS: Add Brandon Lucia.
1961 * data/push.c (yypstate_delete): Free the stack if it was reallocated
1962 but the parse never completed and thus freed it.
1963 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
1964 * tests/testsuite.at: Include push.at.
1965 * test/push.at: New.
1966 (Push Parsing: Memory Leak for Early Deletion): New test case.
1967
1968 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
1969
1970 Improve handling of multiple S/R conflicts in the same state and of S/R
1971 conflicts involving multiple reductions.
1972 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
1973 set for a state here or Bison will abort if it is reassigned on a
1974 later conflicted reduction in the same state.
1975 Similarly, don't finalize and assign the solved conflicts report here
1976 or it will be lost if it is reassigned on a later conflicted reduction
1977 in the same state.
1978 (set_conflicts): Instead, assign them both here after all S/R conflicts
1979 in the state have been fully examined.
1980 * src/print.c (shift_set): Rename to...
1981 (no_reduce_set): ... this.
1982 (print_reductions): Update for rename, and add %nonassoc error action
1983 tokens to no_reduce_set so that, when printing the first remaining
1984 reduction on an error action token, the reduction is enclosed in
1985 brackets.
1986 (print_results): Update for rename.
1987 * tests/conflicts.at (Solved conflicts report for multiple reductions
1988 in a state): New test case.
1989 (%nonassoc error actions for multiple reductions in a state): New test
1990 case.
1991
1992 * src/main.c (main): Don't depend on C99 features.
1993
1994 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
1995
1996 * build-aux/.cvsignore: Add compile.
1997 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
1998 uniwidth.
1999
2000 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
2001
2002 * bootstrap (slurp): Create target directories that don't exist.
2003 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
2004
2005 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
2006
2007 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
2008 than item number.
2009 * closure.c (closure): Likewise.
2010 * state.h (reductions): Comment sorting of rules.
2011 (state): Comment sorting of items.
2012
2013 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2014
2015 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2016 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2017 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2018 definition in order to avoid Gnulib headers since we don't use config.h
2019 here.
2020 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2021 rather than AT_DATA so that config.h is included.
2022
2023 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2024
2025 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2026 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2027 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2028 and so that YYFPRINTF is guaranteed to be defined here.
2029
2030 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2031
2032 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2033 with...
2034 (muscle_percent_define_check_values): ... this more helpful function.
2035 Again, it's not used yet, but it will be.
2036 * src/muscle_tab.h: Likewise.
2037
2038 Improve some comments in parser table construction.
2039 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2040 (generate_states): Don't mention ruleset, which is internal to closure.
2041 * src/closure.c (closure): Explain sorting of core and itemset, which
2042 is required for this function to behave correctly.
2043 * src/closure.h (closure): Mention sorting.
2044
2045 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2046
2047 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2048 move the check for disabled transitions to an aver since conflict
2049 resolution hasn't happened yet.
2050
2051 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2052 labels a state as inconsistent just because it has error transitions.
2053 The original form of this check appeared in revision 1.1 of lalr.c,
2054 which was committed on 1991-12-21. Now (at least), changing the
2055 consistency label on such a state appears to have no useful effect in
2056 any of the places it is examined, which I enumerate below. The key
2057 point to understanding each item in this enumeration is that a state
2058 with an error transition is labelled consistent in the first place only
2059 if it has no rules, so the check cannot matter for states that have
2060 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2061 to try to identify its conflicts, and a state must have *rules* to have
2062 conflicts. (2) Labelling a state as inconsistent will affect how
2063 action_row sets the default *rule* for the state. (3) Labelling a
2064 state as inconsistent will cause build_relations to add lookback edges
2065 to *rules* in that state.
2066 * src/state.h (struct state): Word the comment for member consistent
2067 more carefully.
2068
2069 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2070
2071 Don't depend on C99 features.
2072 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
2073 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
2074 * src/reader.c (check_and_convert_grammar): Fix for-loop.
2075 * src/state.c (state_mark_reachable_states): Fix for-loop.
2076 (state_remove_unreachable_states): Fix for-loop.
2077
2078 Don't widen struct state with member reachable just to temporarily
2079 record reachability. Instead, use a local bitset.
2080 * src/state.h (struct state): Remove member.
2081 * src/state.c (state_new): Don't initialize it.
2082 (state_mark_reachable_states): Rename to...
2083 (state_record_reachable_states): ... this, and use bitset.
2084 (state_remove_unreachable_states): Use bitset.
2085
2086 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
2087
2088 * src/Makefile.am (yacc): Quote target action commands properly so
2089 that the yacc script isn't corrupt. Reported by Hans Aberg at
2090 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
2091
2092 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2093 the case of pure parsers. Reported by Frans Englich at
2094 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
2095 * THANKS: Add Frans Englich.
2096
2097 * NEWS (2.3a+): In the %code entry, reference section `Bison
2098 Declaration Summary' from the manual now since the %code summary has
2099 moved there.
2100 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
2101 in the rules section must be terminated by semicolons.
2102
2103 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
2104
2105 Extend the front-end API for %define variables to more completely
2106 mirror the back-end. This will be useful in the future.
2107 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
2108 Update comments to mention the new front-end counterparts of these
2109 macros.
2110 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code
2111 for muscle_string_decode and muscle_location_decode.
2112 (muscle_string_decode): New static function.
2113 (muscle_location_decode): Use MUSCLE_COMMON_DECODE.
2114 (muscle_percent_define_get, muscle_percent_define_ifdef): New
2115 functions.
2116 (muscle_percent_define_flag_if): Use muscle_percent_define_ifdef and
2117 muscle_percent_define_get to mimic the b4_percent_define_flag_if
2118 implementation more closely.
2119 (muscle_percent_define_invalid_value): New function.
2120 * src/muscle_tab.h (muscle_percent_define_get,
2121 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
2122 Prototype.
2123
2124 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
2125
2126 * NEWS (2.3a+): Mention yesterday's state-removal change.
2127 (2.3a): Remove the %language entry, which was added after 2.3a.
2128 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
2129 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
2130 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
2131 tests/existing.at: Update copyright date.
2132
2133 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2134
2135 If conflict resolution makes states unreachable, remove those states,
2136 report rules that are then unused, and don't report conflicts in those
2137 states.
2138 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
2139 New global function.
2140 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global
2141 function.

2145 false.
2146 (state_mark_reachable_states): New static function.
2147 (state_remove_unreachable_states): New global function.
2148 * src/state.h (struct state): Add member bool reachable.
2149 (state_remove_unreachable_states): Prototype.
2150 * tests/conflicts.at (Unreachable States After Conflict Resolution):
2151 New test case.
2152 * tests/existing.at (GNU pic Grammar): Update test case output now that
2153 an unused rule is discovered.
2154
2155 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>

2226
2227 DJGPP spefic issue. Inhibit the use of disallowed characters for
2228 file name genertion on Win98, WinXP, etc. These are |<>":?*\

2248 %define and %code directives.
2249
2250 Make it easy to share %define boolean variables between the front-end
2251 and back-end. Though not used yet, this will be useful in the future.
2252 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
2253 Bison uses of names rather than just skeleton uses of names.
2254 (b4_percent_define_get, b4_percent_define_ifdef): Rename

2268 b4_percent_define_loc(VARIABLE) to report the location of an invalid
2269 value for VARIABLE.
2270 (b4_percent_define_default): Save a special location in

2272 must later be reported as invalid.
2273 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
2274 functions.
2275 (muscle_percent_define_insert): Record the location of VARIABLE in
2276 muscle percent_define_loc(VARIABLE), and use it to report the previous
2277 location for a redefinition.

2290 * src/print.c (lookahead_set, state_default_rule): Remove.
2291 (print_reductions): Replace state_default_rule invocation with
2292 equivalent use of yydefact, which was computed in token_actions in
2293 tables.c.
2294 (print_results): Don't allocate lookahead_set.
2295
2296 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
2297
2298 * data/lalr1.java: Prefix all private members with yy.
2299
2300 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
2301
2302 Use YYFPRINTF instead of fprintf where appropriate. Reported by
2303 Sebastien Fricker at
2304 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
2305 * THANKS: Add Sebastien Fricker.
2306 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
2307 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must

2319
2320 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
2321
2322 Undo my 2007-02-07 change, switching back to the c-strcase module
2323 introduced in the 2007-02-03 change. Bruno Haible reported that
2324 the 2007-02-07 change would be dangerous in Turkish if we add a
2325 language whose name contains "i", since "i" is not lowercase "I"
2326 in Turkish.
2327 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
2328 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
2329 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
2330 * m4/.cvsignore: Remove strcase.m4.
2331 * src/getargs.c: Revert 2007-02-07 change, as follows.
2332 Include c-strcase.h.
2333 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
2334
2335 2007-02-11 Bruno Haible <bruno@clisp.org>
2336
2337 Enable the Java related testsuite tests when the only Java compiler
2338 found is a gcj < 4.3. Discussed at
2339 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
2340 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
2341
2342 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
2343
2344 * data/Makefile.am: Update copyright date.
2345 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
2346 yypstate_new returns NULL.
2347 (yypstate_new): Return NULL if malloc does.
2348 * src/reader.c (packgram): Move translation of rule actions from the
2349 beginning of packgram to...
2350 (check_and_convert_grammar): ... here right before packgram is invoked
2351 so it's easier to write more complete comments, and remove redundant
2352 code.
2353
2354 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
2355
2356 As in semantic actions, make @$ in %initial-action, %destructor, and
2357 %printer imply %locations.
2358 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
2359 scanning @$.
2360 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
2361 (@$ in %initial-action implies %locations,
2362 @$ in %destructor implies %locations,
2363 @$ in %printer implies %locations): ... these new test cases.
2364
2365 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2366
2367 Undo most of the 2007-02-03 change, switching to the strcase module
2368 now that gnulib strcase has been fixed.
2369 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
2370 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
2371 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
2372 * m4/.cvsignore: Add strcase.m4.
2373 * src/getargs.c: Revert 2007-02-03 change, as follows.
2374 Don't include c-strcase.h.
2375 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
2376 strcasecmp has "unspecified behavior" outside the POSIX locale,
2377 but it works fine in practice if at least one argument is ASCII,
2378 as is the case in Bison.
2379
2380 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
2381
2382 * tests/java.at: Skip tests if only one of javac/java is present.
2383 Reported by Joel E. Denny.
2384 * tests/atlocal.in: Adjust copyright years.
2385
2386 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
2387
2388 * data/lalr1.java (Stack): Work around old verifiers that disallow
2389 access to the private fields of an inner class, from the outer class.
2390 We can make Stack's fields public because user code doesn't have access
2391 to the instance of Stack used by parse(). Reported by Paul Eggert.
2392
2393 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2394
2395 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
2396 the right spot for these files?
2397 * bootstrap.conf (gnulib_modules): Add c-strcase.
2398 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
2399 c-strncasecmp.c.
2400 * src/getargs.c: Include c-strcase.h.
2401 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
2402 to avoid unspecified behavior.
2403
2404 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
2405
2406 * doc/bison.texinfo (Decl Summary): Correct typo.

2409
2410 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.

2422 * bootstrap.conf: Add javacomp-script and javaexec-script.
2423 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
2424
2425 * data/Makefile.am: Add new files.
2426 * data/java-skel.m4: New.
2427 * data/java.m4: New.
2428 * data/lalr1.java: New.
2429
2430 * doc/bison.texinfo: Put "A Complete C++ Example" under
2431 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
2432 under Other Languages.
2433
2434 * src/getargs.c (valid_languages): Add Java.
2435 * src/getargs.h (struct bison_language): Update size of string fields.
2436
2437 * tests/Makefile.am: Add java.at.
2438 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
2439 * tests/java.at: New.
2440 * tests/testsuite.at: Include it.
2441
2442 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
2443
2444 Clean up.
2445 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
2446 at_directive_argv arguments so these no longer have to be global
2447 variables. Also, update the implementation for the following changes.
2448 (fail_for_at_directive_too_many_args,
2449 fail_for_at_directive_too_few_args): Add at_directive_name argument.
2450 (at_directive_name): Remove as at_directive_argv[0] will be used for
2451 this now.
2452 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
2453 for the directive name.
2454 (at_directive_argc, at_directive_argv): Make these local within
2455 skel_lex instead of global.
2456 (INITIAL): Update directive start action for above changes.
2457 (SC_AT_DIRECTIVE_ARG): Rename to...

2462 * tests/skeletons.at (installed skeleton file name): Rename to...
2463 (installed skeleton file names): ... this.
2464
2465 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
2466
2467 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2468 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
2469 Summary" not "Directives".
2470 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
2471 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
2472 since the former is now the more complete one.
2473 (Prologue Alternatives): Likewise and do the same for %defines.
2474 (Table of Symbols): Add summary of %code, add summary of %define, and
2475 move full %code documentation to...
2476 (Decl Summary): ... here for consistency with other entries in these
2477 sections.
2478 Move %define entry in order to keep this list alphabetized.
2479 Reword %define entry a little to put less emphasis on the skeleton
2480 concept, which most users shouldn't have to think about.
2481
2482 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
2483
2484 Adjust to recent gnulib changes.

2488 * src/system.h: Don't include <stpcpy.h>; this is now done by
2489 <string.h>.
2490
2491 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
2492
2493 Simplify implementation of unqualified %code, implement macros for
2494 uniform treatment of boolean %define flags. Document %define.
2495 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
2496 b4_percent_code_ifdef): New.

2513 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
2514 (Bison Options): Document in --skeleton entry.
2515 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
2516 full_skeleton can't necessarily hold all of pkgdatadir.
2517 If the specified skeleton file name contains a `/', don't prepend
2518 pkgdatadir.
2519 * src/parse-gram.y (prologue_declaration): If the specified skeleton
2520 file name contains a `/', prepend the grammar file directory.
2521 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.

2534
2535 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
2536 nonterminals.
2537 Use per-type %printer.
2538
2539 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2540
2541 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

2563 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
2564 and Joel E. Denny <jdenny@ces.clemson.edu>
2565
2566 Clean up %define and %code implementation in M4 some. Most
2567 importantly, rename all related macros to be in the b4_percent_define
2568 and b4_percent_code namespaces. Also, complete support for `.' in
2569 %define variable names and %code qualifiers.
2570 * data/bison.m4 (b4_check_user_names): Check for special
2571 "SKELETON-NAMESPACE(name)" macros instead of using two nested
2572 m4_foreach loops.
2573 (b4_get_percent_define, b4_get_percent_code): Rename to...
2574 (b4_percent_define_get, b4_percent_code_get): ... these.
2575 Extend documentation with examples.
2576 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
2577 b4_percent_define_skeleton_variables and
2578 b4_percent_code_skeleton_qualifiers.
2579 Expect any value for the %define variable `foo' to be stored in the
2580 macro named `b4_percent_define(foo)'; expect any %code blocks for the
2581 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
2582 expect any unqualified %code blocks to be stored in a macro named
2583 `b4_percent_code_unqualified'.
2584 Use m4_indir so that %define variable names and %code qualifiers can
2585 contain `.', which is allowed by the grammar parser.
2586 (b4_percent_define_default): New macro to set a default value for a
2587 %define variable.
2588 (m4_wrap): Update wrapped code, and fix some underquoting.
2589 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
2590 Expect grammar uses of %define variables and %code qualifiers to be
2591 defined in b4_percent_define_user_variables and
2592 b4_percent_code_user_qualifiers.
2593 * data/c++.m4: Use b4_percent_define_default rather than
2594 m4_define_default. Fix some underquoting. Skeleton usage of %define
2595 variable define_location_comparison now implies skeleton usage of
2596 %define variable filename_type.
2597 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2598 data/push.c, data/yacc.c: Update macro names.
2599 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
2600 muscle names.
2601
2602 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2603
2604 DJGPP specific issues.
2605
2606 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
2607 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
2608
2609 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2610
2611 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
2612 run parsers in all tests so that Valgrind is invoked during
2613 maintainer-check-valgrind.
2614 (Duplicate representation of merged trees): Free all semantic values.
2615 (Duplicated user destructor for lookahead): Likewise.
2616
2617 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2618
2619 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
2620 command-line prefix.
2621 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
2622 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
2623 miss Valgrind messages.
2624 (Exploding the Stack Size with Malloc): Likewise.
2625
2626 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2627
2628 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
2629 locals. Reported by Juan Manuel Guerrero at
2630 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
2631 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
2632 Fix some indentation also.
2633 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
2634 explaining this issue.
2635
2636 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
2637 and Joel E. Denny <jdenny@ces.clemson.edu>
2638
2639 Simplify union and prologue handling, and escape union and lex/parse
2640 params with digraphs.
2641 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
2642 values to the empty string since these are no longer guaranteed
2643 initialized by the front-end.
2644 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
2645 braces around b4_user_stype since this is no longer done by the
2646 front-end.
2647 * src/files.c, src/files.h (pre_prologue_obstack,
2648 post_prologue_obstack): Remove.
2649 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
2650 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
2651 with digraphs. This fixes lex params and parse params.
2652 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
2653 * src/output.c (prepare): Remove muscle insertion of the prologues.
2654 (output): Remove freeing of pre_prologue_obstack and
2655 post_prologue_obstack.
2656 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
2657 than prologue_augment for prologue parsing so you don't need prologue
2658 obstacks.
2659 (grammar_declaration): For %union RHS, use `braceless' instead of
2660 "{...}" so that braces are already stripped and code is escaped with
2661 digraphs.
2662 * src/reader.c (prologue_augment): Remove.
2663 (reader): Remove initialization of pre_prologue_obstack and
2664 post_prologue_obstack.
2665 * src/reader.h (prologue_augment): Remove.
2666
2667 * data/c.m4: Remove stray parenthesis.
2668
2669 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2670
2671 Remove quotes from variables names in %define directives and from
2672 qualifiers in %code directives, and restrict the characters that are
2673 allowed in them to M4-friendly ones. For %define, continue to support
2674 the quoted form as a deprecated feature. Discussed starting at
2675 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
2676 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
2677 %code.
2678 * doc/bison.texinfo (Prologue Alternatives): Update.
2679 (Decl Summary): In %defines entry, update mention of `%code requires'
2680 and `%code provides'.
2681 (C++ Location Values): Update %define uses.
2682 (Calc++ Parser Interface): Likewise.
2683 (Calc++ Parser): Likewise, and update `%code requires' uses.
2684 (Table of Symbols): Update %code documentation.
2685 * src/parse-gram.y (prologue_declaration): For %define variables, use
2686 `variable' instead of `STRING'.
2687 (grammar_declaration): For %code qualifiers, use `ID' instead of
2688 `STRING'.
2689 (variable): New nonterminal that takes an `ID' or a `STRING'.
2690 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
2691 and %define uses.
2692 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
2693 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
2694 (%define errors): Update %define uses.
2695
2696 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2697
2698 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
2699 instead of muscle_insert for %define values so that M4-special
2700 characters are replaced with digraphs.
2701 * tests/input.at (%define errors): Extend to check weird values.
2702
2703 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2704
2705 Instead of having skeletons declare all valid %define variables and
2706 %code qualifiers, provide macros that retrieve the associated values
2707 and build these lists automatically. Thus Bison will now warn when a
2708 variable or qualifier is not used by the skeleton in the current
2709 invocation regardless of whether it might sometimes be used by that
2710 skeleton in other invocations. Also, move all %define value macros to
2711 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2712 form, which is replaced by %code.
2713 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2714 (b4_check_user_names): ... this, and change the series of valid name
2715 arguments to a single list argument for names used in the skeleton
2716 similar to the existing list argument for names used in the grammar.
2717 Warn instead of complaining.
2718 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2719 values and %code code, to format %code code properly, and to build
2720 lists of all %define variables and %code qualifiers used in the
2721 skeleton: b4_skeleton_percent_define_variables and
2722 b4_skeleton_percent_code_qualifiers.
2723 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
2724 Remove, and...
2725 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
2726 the skeleton names lists can finish building first. In place of
2727 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
2728 expect the lists b4_user_percent_define_variables and
2729 b4_user_percent_code_qualifiers.
2730 * data/c++.m4: Where setting default values for b4_parser_class_name,
2731 b4_location_type, b4_filename_type, b4_namespace, and
2732 b4_define_location_comparison, update their names to the
2733 b4_percent_define_ namespace.
2734 * data/glr.c: Don't use b4_check_percent_define_variables and
2735 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2736 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
2737 (b4_parser_class_name, b4_namespace): Define these using
2738 b4_get_percent_define for parser_class_name and namespace.
2739 * data/location.cc: Use b4_get_percent_define.
2740 * data/push.c: Don't use b4_check_percent_define_variables and
2741 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2742 * data/yacc.c: Likewise, and don't call m4_exit in
2743 b4_use_push_for_pull_if or m4_wrap code will never execute.
2744 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
2745 Rename to...
2746 (muscle_grow_user_name_list): ... this for consistency with the
2747 terminology used in bison.m4.
2748 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
2749 %define variable names, and rename muscle used_percent_define_variables
2750 to user_percent_define_variables.
2751 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
2752 user_percent_code_qualifiers.
2753 (content): Remove.
2754 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
2755 {CODE} form is no longer accepted.
2756 * tests/input.at (Reject bad %code qualifiers): Rename to...
2757 (Reject unused %code qualifiers): ... this, and update test output.
2758 (%define error): Update test output.
2759
2760 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
2761
2762 Check for unrecognized %define variables similar to checking for
2763 unrecognized %code qualifiers. Check for redefined %define variables.
2764 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
2765 generalizes...
2766 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
2767 (b4_check_percent_define_variables): New, also wraps it.
2768 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
2769 variables using b4_check_percent_define_variables.
2770 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
2771 all those exercised in the test suite and all those listed in the
2772 `Default values' section of c++.m4. Are there others?
2773 * data/push.c, data/yacc.c: Declare no valid %define variables.
2774 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
2775 similar to muscle_find, but it works even when the muscle stores a
2776 const value.
2777 (muscle_grow_used_name_list): New function for constructing the used
2778 name list muscles that b4_check_for_unrecognized_names requires.
2779 * src/parse-gram.y (prologue_declaration): Warn if a variable is
2780 %define'd more than once. Define the b4_used_percent_define_variables
2781 muscle with muscle_grow_used_name_list.
2782 (grammar_declaration): Abbreviate %code code with
2783 muscle_grow_used_name_list.
2784 * tests/input.at (%define errors): New.
2785
2786 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2787
2788 Provide warn_at, complain_at, and fatal_at function callbacks to the
2789 skeletons, and use this for %code qualifier complaints.
2790 * data/bison.m4 (b4_error_at): New, invoked by...
2791 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
2792 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
2793 @fatal_at(...@) directives.
2794 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
2795 qualifiers in b4_used_percent_code_qualifiers and to use
2796 b4_complain_at.
2797 * src/location.c, src/location.h (boundary_set_from_string): New global
2798 function.
2799 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
2800 function.
2801 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
2802 to b4_used_percent_code_qualifiers.
2803 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
2804 function.
2805 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
2806 (lineno): Rename to...
2807 (out_lineno): ... this so I don't misunderstand it again.
2808 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
2809 here; these newlines are in the input but not the output file.
2810 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
2811 (at_directive_perform): ... this new static function, and add handling
2812 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
2813 directives.
2814 * tests/input.at (Reject bad %code qualifiers): Update test output with
2815 locations and extend.
2816
2817 * tests/output.at (Output file name: [, Output file name: ]): Remove
2818 bogus comment about these tests failing.
2819
2820 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2821
2822 Clean up b4_check_percent_code_qualifiers a little.
2823 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
2824 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
2825 documentation and add examples.
2826 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
2827 qualifiers here.
2828
2829 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2830
2831 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
2832 unreliable -- especially when they're hidden inside another macro.
2833 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
2834 data/c.m4: Remove m4_divert(-1).
2835 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2836 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
2837 m4_divert_push(0) and m4_divert_pop(0).
2838 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
2839 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
2840 pushed and popped by m4sugar, should be first on the stack.
2841
2842 Provide warn, complain, and fatal function callbacks to the skeletons.
2843 This provides more flexibility than m4_fatal, improves the error
2844 message format, and captures messages for translation. Discussed
2845 starting at
2846 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
2847 * data/bison.m4 (b4_error): New, invoked by...
2848 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
2849 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
2850 directives. Because these M4 macros might be called when the current
2851 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
2852 the previous removal of uses of m4_divert, which caused trouble.
2853 (b4_check_percent_code_qualifiers): Use b4_complain instead of
2854 m4_fatal to report unrecognized %code qualifiers.
2855 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
2856 push parser requests.
2857 * data/glr.c: Use b4_complain instead of m4_fatal to report
2858 non-deterministic push parser requests.
2859 Update @output usage to @output(...@) form.
2860 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
2861 report missing %defines. Update @output usage to @output(...@) form.
2862 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
2863 @output(...@) form.
2864 * src/main.c (main): Invoke skel_scanner_free.
2865 * src/scan-skel.h (skel_scanner_free): Prototype new function.
2866 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
2867 obstack_for_string from flex-scanner.h.
2868 (YY_DECL): Use to declare skel_lex static.
2869 (decode_at_digraphs): Remove; now handled in the new
2870 SC_AT_DIRECTIVE_ARG start condition.
2871 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
2872 functions.
2873 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
2874 at_directive_argv): New static globals.
2875 (INITIAL): Use fail_for_invalid_at.
2876 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
2877 recognize the start of a generalized `@directive(...@)' form and
2878 start...
2879 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
2880 directive args (using the new obstack_for_string), to decode the
2881 contained @ diagraphs, and to perform the directive. It recognizes
2882 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
2883 @output(...@).
2884 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
2885 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
2886 `@,'.
2887 (scan_skel): Initialize obstack_for_string on the first call.
2888 (skel_scanner_free): New function to free obstack_for_string.
2889 * tests/input.at (Reject bad %code qualifiers): Update test output.
2890
2891 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
2892
2893 Consolidate the 4 prologue alternative directives (%code, %requires,
2894 %provides, and %code-top) into a single %code directive with an
2895 optional qualifier field. Discussed at
2896 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
2897 * NEWS (2.3a+): Rewrite the existing entry for the prologue
2898 alternatives.
2899 * doc/bison.texinfo (Prologue Alternatives): Update.
2900 (Decl Summary): Update to %code "requires" and %code "provides".
2901 (Calc++ Parser): Update to %code "requires".
2902 (Table of Symbols): Remove entries for %requires, %provides, and
2903 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
2904 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
2905 are replaced by b4_percent_code_provides and b4_percent_code_requires,
2906 which are skeleton-specific.
2907 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
2908 declare what %code qualifiers it supports and to complain if any other
2909 qualifiers were used in the grammar.
2910 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
2911 and b4_user_code([b4_percent_code_provides]) in place of
2912 b4_user_requires and b4_user_provides.
2913 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
2914 Add b4_user_code([b4_percent_code_top]) and
2915 b4_user_code([b4_percent_code]).
2916 Invoke b4_check_percent_code_qualifiers.
2917 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2918 PERCENT_REQUIRES): Remove.
2919 (grammar_declaration): Remove RHS's for %code-top, %provides, and
2920 %requires. Rewrite the %code RHS as the unqualified form defining the
2921 muscle b4_percent_code. Add another RHS for the qualified %code form,
2922 which defines muscles of the form b4_percent_code_QUALIFIER and the
2923 b4_used_percent_code_qualifiers muscle.
2924 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2925 PERCENT_REQUIRES): Remove.
2926 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
2927 %code "requires" and %code "provides".
2928 * tests/input.at (Reject bad %code qualifiers): New.
2929
2930 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2931
2932 Use the new code_props interface for destructors and printers.
2933 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
2934 printer_location members, and change the type of the destructor and
2935 printer members to code_props.
2936 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
2937 symbol_printer_get, semantic_type_destructor_set,
2938 semantic_type_printer_set, default_tagged_destructor_set,
2939 default_tagless_destructor_set, default_tagged_printer_set,
2940 default_tagless_printer_set): Use code_props in arguments and return
2941 types in place of char const * and location.
2942 (symbol_destructor_location_get, symbol_printer_location_get): Remove
2943 since the locations are now contained in the return of
2944 symbol_destructor_get and symbol_printer_get.
2945 * src/output.c (symbol_destructors_output, symbol_printers_output):
2946 Replace with...
2947 (symbol_code_props_output): ... this to eliminate duplicate code.
2948 (output_skeleton): Update to use symbol_code_props_output.
2949 * src/reader.c (symbol_should_be_used): Update use of
2950 symbol_destructor_get.
2951 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
2952 Update uses of the various _destructor_set and _printer_set functions.
2953 * src/symtab.c: (default_tagged_destructor_location,
2954 default_tagless_destructor_location, default_tagged_printer_location,
2955 default_tagless_printer_location): Remove since we...
2956 (default_tagged_destructor, default_tagless_destructor,
2957 default_tagged_printer, default_tagless_printer): ... change the type
2958 of these to code_props.
2959 (symbol_new, semantic_type_new, symbol_destructor_set,
2960 semantic_type_destructor_set, symbol_destructor_get,
2961 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
2962 symbol_check_alias_consistency, default_tagged_destructor_set,
2963 default_tagless_destructor_set, default_tagged_printer_set,
2964 default_tagless_printer_set): Update.
2965 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
2966 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
2967 code_props members.
2968 (symbol_print): Use SYMBOL_CODE_PRINT.
2969
2970 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2971
2972 Use the new code_props interface for rule actions.
2973 * src/symlist.h (symbol_list): Replace action, action_location, and
2974 used members with a code_props action_props member.
2975 * src/reader.c (symbol_should_be_used, grammar_rule_check,
2976 grammar_midrule_action, grammar_current_rule_merge_set,
2977 grammar_current_rule_symbol_append, packgram): Update.
2978 * src/scan-code.h (translate_rule_action): Remove, no longer used.
2979 * src/scan-code.l (handle_action_dollar): Update.
2980 (translate_rule_action): Remove, no longer used.
2981 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
2982
2983 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2984
2985 Use the new code_props interface in parse-gram.y.
2986 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
2987 Update all uses of translate_* functions to use the new code_props
2988 interface and to use gram_scanner_last_string_free and
2989 code_scanner_last_string_free where possible.
2990 (grammar_declaration): symbol_list_destructor_set and
2991 symbol_list_printer_set now perform the translation, so don't do it
2992 here. Use gram_scanner_last_string_free where possible.
2993 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
2994 translate_code): Remove, no longer used.
2995 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
2996 symbol_list_printer_set): Perform code translation here rather than
2997 depending on the caller to do so.
2998
2999 * src/symlist.h (struct symbol_list): Correct some documentation typos.
3000 * src/scan-gram.h (gram_last_string): Remove declaration.
3001 * src/scan-gram.l (last_string): Declare it static.
3002
3003 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3004
3005 Encapsulate code properties and related functionality for the various
3006 destructors, printers, and actions into a code_props structure and
3007 interface. This patch merely implements code_props in scan-code.h and
3008 scan-code.l. Future patches will rewrite other modules to use it.
3009 Discussed starting at
3010 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3011 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3012 consistently initialize const structs that have an empty location
3013 field.
3014 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3015 to ensure consistency.
3016 * src/scan-code.h (code_props): New structure.
3017 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3018 function, macro, and const global variable for initializing a
3019 code_props with no code.
3020 (code_props_plain_init, code_props_symbol_action_init,
3021 code_props_rule_action_init, code_props_translate_code): The rest of
3022 the new code_props functional interface. Among other things, the init
3023 functions set the code_props kind field so that
3024 code_props_translate_code will know whether to behave like
3025 translate_symbol_action, translate_rule_action, or translate_code.
3026 These old translate functions must remain until all other modules are
3027 updated to use the new code_props interface.
3028 (code_scanner_last_string_free): New function similar to
3029 gram_scanner_last_string_free.
3030 (code_scanner_free): Add documentation.
3031 * src/scan-code.l: Implement the new interface.
3032 (code_lex): Make it static, add a code_props* argument, and remove the
3033 rule argument.
3034 (last_string): New static global similar to the one in scan-gram.l.
3035 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3036 instead of rule.
3037 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3038 code_props since Bison may one day use this information for destructors
3039 and printers.
3040 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3041 (handle_action_dollar): Use symbol_list_n_get and set used flag
3042 directly since symbol_list_n_used_set is removed.
3043 (translate_action): Add a code_props* argument and remove the rule,
3044 action, and location arguments. Pass the code_props* on to code_lex.
3045 (translate_rule_action, translate_symbol_action, translate_code):
3046 Rewrite as wrappers around the new code_props interface.
3047 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3048 it would eventually need to break the encapsulation of code_props.
3049
3050 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3051
3052 * etc/.cvsignore: New.
3053
3054 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3055
3056 Add maintainer-push-check to run maintainer-check using push parsing in
3057 place of pull parsing where available.
3058 * Makefile.am (maintainer-push-check): New.
3059 * data/bison.m4 (b4_use_push_for_pull_if): New.
3060 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3061 appropriately based on their existing values.
3062 (yypush_parse): Don't print push-parser-specific diagnostics if push
3063 parsing is being used in place of pull parsing.
3064 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3065 push.c.
3066 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3067 variable, and insert b4_use_push_for_pull_flag into muscles.
3068 * tests/Makefile.am (maintainer-push-check): New.
3069
3070 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3071
3072 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3073 (whether successful or failed) so that yypush_parse can be invoked
3074 again to start a new parse using the same yypstate.
3075 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3076 check multiple yypull_parse invocations on the same yypstate. For pull
3077 mode, extend to check multiple yyparse invocations.
3078 (Exploding the Stack Size with Alloca): Extend to try with
3079 %push-pull-parser.
3080 (Exploding the Stack Size with Malloc): Likewise.
3081
3082 * tests/calc.at (Simple LALR Calculator): Don't specify
3083 %skeleton "push.c" since %push-pull-parser implies that now.
3084 * tests/headers.at (export YYLTYPE): Don't check for the push
3085 declarations. Otherwise, this test case can't be used to see if push
3086 mode can truly emulate pull mode.
3087 * tests/input.at (Torturing the Scanner): Likewise.
3088 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3089 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3090 AT_YACC_IF, which now includes the case of push mode since %skeleton
3091 need not be used for push mode. This will be more intuitive once
3092 push.c is renamed to yacc.c.
3093
3094 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3095
3096 For push mode, convert yyparse from a macro to a function, invoke yylex
3097 instead of passing a yylexp argument to yypull_parse, and don't
3098 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3099 Discussed starting at
3100 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
3101 * data/bison.m4 (b4_pull_if): New.
3102 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
3103 * data/push.c: Improve M4 quoting a little.
3104 (b4_generate_macro_args, b4_parenthesize): Remove.
3105 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3106 any time a pull parser is requested.
3107 Don't #define this as a wrapper around yypull_parse. Instead, when
3108 both push and pull are requested, make it a function that does that
3109 same thing.
3110 (yypull_parse): If there's a b4_prefix, #define this to
3111 b4_prefix[pull_parse] when both push and pull are requested.
3112 Don't define this as a function unless both push and pull are
3113 requested.
3114 Remove the yylexp argument and hard-code yylex invocation instead.
3115 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3116 %push-parser.
3117 * src/getargs.c (pull_parser): New global initialized to true.
3118 * getargs.h (pull_parser): extern it.
3119 * src/output.c (prepare): Insert pull_flag muscle.
3120 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
3121 (prologue_declaration): Set both push_parser and pull_parser = true for
3122 %push-pull-parser. Set push_parser = true and pull_parser = false for
3123 %push-parser.
3124 * src/scan-gram.l: Don't accept %push_parser as an alternative to
3125 %push-parser since there's no backward-compatibility concern here.
3126 Scan %push-pull-parser.
3127 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
3128 instead of %push-parser.
3129 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
3130 prototype it in the module that calls yyparse.
3131 * tests/input.at (Torturing the Scanner): Likewise.
3132 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
3133
3134 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
3135
3136 Update etc/bench.pl. Optimize push mode a little (the yyn change
3137 deserves most of the credit).
3138 * Makefile.am (SUBDIRS): Add etc subdirectory.
3139 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
3140 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
3141 yytoken, yyval, and yyloc declarations to...
3142 (yyparse or yypush_parse): ... here to improve performance. For
3143 yypush_parse invocations after the first, be sure to assign yyn its old
3144 value again.
3145 (yypstate_new): Don't bother initializing the yyresult field since the
3146 initial value isn't used.
3147 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3148 remove the #define that, in push mode, set it to yyps->NAME.
3149 * etc/Makefile.am: New.
3150 * etc/bench.pl: Remove and build it instead from...
3151 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3152 "tests/bison" from the build directory by default rather than just
3153 invoking "bison" from $PATH.
3154 (calc_grammar): Update push parser code: don't declare yylval globally,
3155 don't define yyparse_wrapper, and don't #define yyparse.
3156 (bench_grammar): Update to check all working combinations of yacc.c,
3157 push.c, impure, pure, pull, and push.
3158
3159 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3160
3161 For push mode, add pull wrappers around yypush_parse.
3162 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
3163 (yypull_parse): New function wrapping yypush_parse.
3164 (yyparse): New #define wrapping yypull_parse.
3165 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
3166 is declared.
3167 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
3168 prototype yylex in the module that calls yyparse, and don't prototype
3169 yyparse there. Otherwise, the yyparse expansion won't compile.
3170 * tests/input.at (Torturing the Scanner): Likewise.
3171
3172 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3173
3174 Enable push parsers to operate in impure mode. Thus, %push-parser no
3175 longer implies %pure-parser. The point of this change is to move
3176 towards being able to test the push parser code by running the entire
3177 test suite as if %push-parser had been declared.
3178 * data/push.c (yypush_parse): For impure mode, remove the
3179 yypushed_char, yypushed_val, and yypushed_loc arguments.
3180 Instead, declare these as local variables initialized to the global
3181 yychar, yylval, and yylloc.
3182 For the first yypush_parse invocation only, restore the initial values
3183 of these global variables when it's time to read a token since they
3184 have been overwritten.
3185 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3186 %push-parser.
3187 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3188 %pure-parser along with %push-parser since this test case was designed
3189 for pure push parsers.
3190 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
3191 (AT_YACC_OR_PUSH_IF): New.
3192 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
3193 add a note that it's still wrong for some cases (as it has been for a
3194 while).
3195 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
3196 %push-parser no longer implies %pure-parser.
3197
3198 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3199
3200 Remove some unnecessary differences between the pull parser code and
3201 the push parser code. This patch enables yynerrs in push mode.
3202 * data/push.c: Reformat M4 a little.
3203 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
3204 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
3205 because push mode is on. Instead, if pure mode is on, move yynerrs
3206 to...
3207 (b4_declare_parser_state_variables): ... here.
3208 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
3209 to yyps->NAME so it can be used in yypush_parse.
3210 (yypush_parse): Don't omit uses of yynerrs in push mode.
3211
3212 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3213
3214 Fix bug such that the first pushed token's value and location are
3215 sometimes overwritten (sometimes by %initial-action) before being used.
3216 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
3217 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
3218 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
3219 more closely mimic the pull parser logic.
3220 Don't copy the pushed token to yychar, yylval, and yylloc until it's
3221 time to read a token, which is after any initialization of yylval and
3222 yylloc.
3223 (gottoken): Rename label to...
3224 (yyread_pushed_token): ... for clarity and to avoid infringing on the
3225 user namespace.
3226
3227 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3228
3229 Rearrange initialization of the parser state variables so that the
3230 skeleton doesn't have to have a copy for pull mode and another for push
3231 mode. This patch also fixes at least a bug such that yylloc was not
3232 initialized (with b4_location_initial_line and
3233 b4_location_initial_column) upon calling yypush_parse. However, that
3234 initialization now overwrites the first token's location;
3235 %initial-action assigning @$ already did the same thing, and both bugs
3236 will be fixed in a later patch.
3237 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
3238 (b4_declare_parser_state_variables): Remove initialization of yytoken,
3239 yyss, yyvs, yyls, and yystacksize.
3240 (yypstate_new): Remove initialization of some yypstate fields: yystate,
3241 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
3242 yylsp.
3243 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
3244 yyps->NAME so it can be used in yypush_parse.
3245 (yyparse or yypush_parse): For yypush_parse, don't print the
3246 "Starting parse" diagnostic for invocations after the first.
3247 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3248 yypush_parse, only do it for the first invocation.
3249 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
3250 initialization to occur in yypush_parse but only on the first
3251 invocation.
3252
3253 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3254
3255 * data/push.c: Add CPP guards around push parser declarations in both
3256 the header and the code file.
3257 In the code file, move the push parser declarations to the same place
3258 they appear in the header file.
3259 Clean up the M4 some, especially the inconsistent underquoting in
3260 some b4_c_function_def and b4_c_function_decl uses.
3261
3262 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3263
3264 Encapsulate the push parser state variables into an M4 macro so the
3265 push skeleton doesn't have to list them again for pull mode's yyparse.
3266 For push mode, remove yypush_parse's local equivalents of these
3267 variables to eliminate unnecessary copying between the two sets at
3268 run-time. This patch also fixes at least a bug related to multiple
3269 %initial-action invocations in push mode.
3270 * data/push.c (b4_declare_parser_variables): Rename to...
3271 (b4_declare_scanner_communication_variables): ... this for clarity and
3272 update both uses.
3273 (b4_declare_yyparse_variables): Remove and move its contents to the one
3274 spot where it was invoked.
3275 (b4_declare_parser_state_variables): New macro containing the parser
3276 state variables required by push mode.
3277 (struct yypstate): Replace all fields but yynew with
3278 b4_declare_parser_state_variables.
3279 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
3280 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
3281 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
3282 (yyparse or yypush_parse): For yyparse in pull mode, replace local
3283 parser state variable declarations with
3284 b4_declare_parser_state_variables.
3285 Don't initialize parser state variables when calling yypush_parse since
3286 yypstate_new already does that.
3287 Invoke the user's initial action only upon the first yypush_parse
3288 invocation.
3289 Remove all code that copies between the local parser state variables
3290 and the yypstate.
3291
3292 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3293
3294 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
3295 prevent a name collision in a future patch where these names will
3296 sometimes be #define'd.
3297 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
3298 since it no longer has the same name as the existing argument.
3299 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
3300
3301 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
3302 and Joel E. Denny <jdenny@ces.clemson.edu>
3303
3304 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
3305 that the argument is case-insensitive, and there's no `=' here.
3306 For the %skeleton entry, mention that %language is better.
3307 (Bison Options): Likewise for --language and --skeleton. Move the
3308 --skeleton entry so that the `Tuning the parser' section is sorted
3309 alphabetically on long options.
3310 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
3311 %language directive in detail here; cross-reference the %language
3312 documentation instead.
3313 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
3314 `%require "2.3b"' so that the example is always up-to-date.
3315 (Table of Symbols): Add entries for %language and %skeleton.
3316 * examples/extexi (normalize): Instead of replacing every %require
3317 argument with the current Bison version, just substitute for
3318 `@value{VERSION}'. This guarantees that we're testing what actually
3319 appears in the documentation.
3320 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
3321 rather than `@VERSION@'.
3322
3323 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3324
3325 * NEWS: Reword the %language news a bit, and put it earlier.
3326
3327 * src/getargs.c (skeleton_arg): Last arg is now location const *.
3328 Rewrite to simplify the logic.
3329 (language_argmatch): Likewise.
3330 (program_name): We now own this var.
3331 * src/getargs.h (struct bison_language): Use char[] rather than
3332 const char *.
3333
3334 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
3335 Java is supported.
3336 * src/complain.c (program_name): Remove decl; no longer needed.
3337 * src/main.c (program_name): Remove; now belongs to getargs.
3338
3339 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
3340
3341 * NEWS: Document %language.
3342
3343 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
3344
3345 * data/c-skel.m4, data/c++-skel.m4: New files.
3346 * data/glr.c: Complain on push parsers.
3347
3348 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
3349 over %skeleton.
3350 (Decl Summary): Document %language and %skeleton.
3351 (Command line): Document -L.
3352
3353 * examples/extexi: Rewrite %require directive.
3354 * examples/calc++/Makefile.am: Pass VERSION to extexi.
3355
3356 * src/files.c (compute_exts_from_gc): Look in language structure
3357 for .y extension.
3358 (compute_file_name_parts): Check whether .tab should be added.
3359 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
3360 (language, skeleton_arg, language_argmatch): New.
3361 (long_options): Add --language.
3362 (getargs): Use skeleton_arg, add -L/--language.
3363 * src/getargs.h: Include location.h.
3364 (struct bison_language, language, skeleton_arg, language_argmatch): New.
3365 * src/output.c (prepare): Pick default skeleton from struct language.
3366 Don't dispatch C skeletons here.
3367 * src/parse-gram.y (PERCENT_LANGUAGE): New.
3368 (prologue_declaration): Add "%language" rule, use skeleton_arg.
3369 * src/scan-gram.l ("%language"): New rule.
3370
3371 * tests/calc.at: Test %skeleton and %language.
3372 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
3373 (AT_GLR_IF): Look for %skeleton "glr.cc".
3374 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
3375 (AT_YACC_IF): Reject %language.
3376
3377 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3378
3379 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
3380 since it wasn't used; only the typedef name 'semantic_type' is needed.
3381 Also, omit trailing white space.
3382
3383 * bootstrap: Sync from coreutils.
3384 (gnulib_extra_files): Add build-aux/announce.gen.
3385 (slurp): Adjust .gitignore files like .cvsignore files.
3386 * build-aux/announce-gen: Remove from CVS, since bootstrap
3387 now creates this.
3388
3389 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
3390
3391 Make %push-parser imply %pure-parser. This fixes several bugs; see
3392 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
3393 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
3394 pure_parser = true.
3395 * data/push.c: Don't bother testing b4_push_if when deciding whether
3396 to expand b4_declare_parser_variables globally.
3397 (yypush_parse): Likewise in here.
3398
3399 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
3400 (yy_reduce_print): Reformat M4 for readability.
3401
3402 2006-12-15 Bob Rossi <bob@brasko.net>
3403 and Joel Denny <jdenny@ces.clemson.edu>
3404
3405 * data/push.c (yypstate): Add typedef, and update all uses of
3406 struct yypstate to just yypstate.
3407 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
3408
3409 2006-12-14 Bob Rossi <bob@brasko.net>
3410
3411 * data/push.c (yypush_parse): Declare prototype regardless of
3412 %locations option.
3413
3414 2006-12-14 Bob Rossi <bob@brasko.net>
3415
3416 * data/push.c (yyparse): Remove the prototype and the #define when in
3417 push-parser mode.
3418
3419 2006-12-13 Bob Rossi <bob@brasko.net>
3420
3421 * data/push.c (yypstate_init): Rename to...
3422 (yypstate_new): ... this and use b4_c_function_def.
3423 (yypstate_delete): New.
3424 (yypush_parse): Change parameters yynval and yynlloc to be const.
3425 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
3426 yypstate_delete functions.
3427
3428 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
3429
3430 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
3431 strange test case titles. Reported by Bob Rossi.
3432
3433 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
3434
3435 * TODO: Add pointer to Sylvain Schmitz's work on static detection
3436 of potential ambiguities in GLR grammers.
3437
3438 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
3439
3440 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3441 `bison ', use m4_index instead of m4_substr since chopping up a string
3442 containing M4-special characters causes problems here.
3443
3444 Fix a couple of bugs related to special characters in user-specified
3445 file names, and make it easier for skeletons to compute output file
3446 names with the same file name prefix as Bison-computed output file
3447 names.
3448 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3449 b4_parser_file_name and b4_spec_defines_file instead of
3450 @output_parser_name@ and @output_header_name@, which are now redundant.
3451 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3452 b4_parser_file_name, b4_spec_defines_file, and the new
3453 @basename(FILENAME@) instead of @output_parser_name@ and
3454 @output_header_name@, which inappropriately escaped the file names as
3455 C string literals.
3456 * src/files.c (all_but_ext): Remove static qualifier.
3457 (compute_output_file_names): Move `free (all_but_ext)' to...
3458 (output_file_names_free): ... here since all_but_ext is needed later.
3459 * src/files.h (all_but_ext): Extern.
3460 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
3461 exactly what MUSCLE_INSERT_STRING used to do.
3462 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
3463 characters are escaped properly.
3464 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3465 all_but_ext.
3466 For pkgdatadir muscle, maintain previous functionality by using
3467 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3468 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3469 digraphs would never be expanded. Hopefully no one has M4-special
3470 characters in his Bison installation path.
3471 * src/scan-skel.l: Don't parse @output_header_name@ and
3472 @output_parser_name@ anymore since they're now redundant.
3473 In @output, use decode_at_digraphs.
3474 Parse a new @basename command that invokes last_component.
3475 (decode_at_digraphs): New.
3476 (BASE_QPUTS): Remove unused.
3477 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
3478 (Output file name): New tests.
3479
3480 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
3481
3482 Warn about output files that are generated by the skeletons and that
3483 conflict with other output files.
3484 * data/glr.c: Don't generate the header file here when glr.cc does.
3485 * src/files.c (file_names, file_names_count): New static globals.
3486 (compute_output_file_names): Invoke output_file_name_check for files
3487 not generated by the skeletons and remove existing checks.
3488 (output_file_name_check): New function that warns about conflicting
3489 output file names.
3490 (output_file_names_free): Free file_names.
3491 * src/files.h (output_file_name_check): Declare.
3492 * src/scan-skel.l: Invoke output_file_name_check for files generated by
3493 the skeletons.
3494 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
3495 (Conflicting output files): New tests.
3496
3497 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3498
3499 * doc/bison.texinfo: Fix a couple of typos.
3500
3501 2006-12-08 Bob Rossi <bob@brasko.net>
3502
3503 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
3504 Rename to...
3505 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
3506 update all uses.
3507 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
3508 (yypush_parse): Rename yypvars argument to yyps and remove redundant
3509 local pv.
3510 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
3511 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
3512
3513 2006-12-07 Bob Rossi <bob@brasko.net>
3514 and Joel Denny <jdenny@ces.clemson.edu>
3515
3516 * data/push.c (yypvarsinit): Change return type from void* to struct
3517 yypvars*. No longer cast to void* on return.
3518 (struct yypvars): Remove yylen since it need not be remembered between
3519 yypushparse invocations.
3520 (yypushparse): Don't copy between yylen and pv->yylen.
3521
3522 2006-12-05 Bob Rossi <bob@brasko.net>
3523
3524 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
3525 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
3526 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
3527 (struct yypvars): Remove b4_declare_parser_variables.
3528 (yypvarsinit): Remove init code for removed variables.
3529 (global scope): Do not declare b4_declare_parser_variables if
3530 push or pure mode.
3531 (yypushparse): Add b4_declare_parser_variables.
3532 Init new local variables, and remove init code for removed
3533 yypvars variables.
3534 (yyparse): Delete.
3535 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
3536 and yyparse for other modes.
3537 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
3538 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
3539 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
3540 (AT_PURE_LEX_IF): True if pure or push parser.
3541
3542 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
3543
3544 Document Yacc prologue alternatives and default %destructor's and
3545 %printer's as experimental. Don't mention Java yet. Discussed at
3546 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
3547 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
3548 (2.3a): Annotate this entry to say the old forms of these features were
3549 also experimental.
3550 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,
3551 Table of Symbols): Say they're experimental. Comment out any mention
3552 of Java (we'll want this back eventually).
3553
3554 2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
3555
3556 Support a file name argument to %defines. Deprecate `=' in
3557 %file-prefix, %name-prefix, and %output. Discussed at
3558 <http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
3559 * NEWS (2.3a+): Mention.
3560 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
3561 form of %defines, and remove `=' from entries for %file-prefix,
3562 %name-prefix, and %output.
3563 * src/parse-gram.y (prologue_declaration): Implement.
3564 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
3565 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
3566 all but one occurrence of %name-prefix.
3567 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
3568 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
3569 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
3570 occurrence of each of %file-prefix and %output. Add check for %defines
3571 with argument.
3572 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
3573 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
3574 Remove the `=' from %output.
3575
3576 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
3577
3578 Don't escape $ in test case titles since Autoconf 2.61 now does that
3579 correctly.
3580 * tests/actions.at (Default %printer and %destructor are not for error
3581 or $undefined): Here.
3582 (Default %printer and %destructor are not for $accept): Here.
3583 * tests/input.at (Invalid $n and @n): Here.
3584
3585 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
3586
3587 Rename <!> to <>. Discussed starting at
3588 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
3589 * NEWS (2.3a+): Update.
3590 * doc/bison.texinfo (Freeing Discarded Symbols, Table of Symbols):
3591 Update.
3592 * src/parse-gram.y (TYPE_TAG_NONE, generic_symlist_item): Implement.
3593 * src/scan-gram.l (INITIAL): Implement.
3594 * src/symlist.c (symbol_list_default_tagless_new): Update comment.
3595 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
3596 comment.
3597 * tests/actions.at (Default tagless %printer and %destructor,
3598 Default tagged and per-type %printer and %destructor,
3599 Default %printer and %destructor are not for error or $undefined,
3600 Default %printer and %destructor are not for $accept,
3601 Default %printer and %destructor for mid-rule values): Update.
3602 * tests/input.at (Default %printer and %destructor redeclared,
3603 Unused values with default %destructor): Update.
3604
3605 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
3606
3607 Don't let %prec take a nonterminal.
3608 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
3609 token.
3610 * tests/input.at (%prec takes a token): New test checking that %prec
3611 won't take a nonterminal.
3612
3613 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
3614
3615 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
3616 it was double-quoted.
3617 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
3618 grammar is maintained with Bison's highest standards.
3619 * src/getargs.c: Fix some typos in Doxygen comments.
3620
3621 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
3622
3623 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
3624 later. Reported by Paul Eggert in
3625 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
3626 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
3627 * src/scan-code.l (translate_action): Don't bother invoking
3628 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
3629 (code_scanner_free): Instead of invoking
3630 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
3631 which frees more.
3632 * src/scan-gram.l (gram_scanner_free): Likewise.
3633 * src/scan-skel.l (scan_skel): Likewise.
3634
3635 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
3636
3637 * src/files.c (tr): Change return type to void.
3638 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
3639 has been called previously for the same key.
3640 (muscle_find): Return storage instead of value so that
3641 --enable-gcc-warnings doesn't produce warnings that the return discards
3642 const. aver that the value and storage are the same since storage
3643 could potentially be NULL when value is not.
3644 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
3645 same as 0.
3646
3647 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3648
3649 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
3650 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
3651 us a slightly cleaner distribution, and also works.
3652 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
3653 gnulib changes.
3654
3655 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
3656 and Paul Eggert <eggert@cs.ucla.edu>
3657
3658 Don't let Bison leak memory except when it complains.
3659 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
3660 (spec_defines_file, dir_prefix): Now char *, not const char *,
3661 since they are freed.
3662 * src/files.c: Likewise.
3663 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
3664 Likewise.
3665 (tr): Now operates in-place. All uses changed.
3666 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
3667 values.
3668 (compute_file_name_parts, compute_output_file_names): Don't store
3669 read-only data in variables that will be freed.
3670 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
3671 src_extension, and header_extension.
3672 (output_file_names_free): New public function to free
3673 spec_verbose_file, spec_graph_file, spec_defines_file,
3674 parser_file_name, and dir_prefix.
3675 * src/getargs.c (getargs): Don't store read-only data in variables that
3676 will be freed.
3677 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
3678 (which previously existed but was unused), and quotearg_free.
3679 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
3680 * src/muscle_tab.c: Likewise.
3681 (muscle_entry): Make the value char const *,
3682 and add a new storage member that is char * and can be freed.
3683 (muscle_entry_free): New private function.
3684 (muscle_init): Use it instead of free.
3685 (muscle_insert, muscle_grow): Update and use new storage member.
3686 (muscle_code_grow): Free the string passed to muscle_grow
3687 since it's not needed anymore.
3688 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
3689 add a new `char *code' member.
3690 ("{...}"): Declare semantic type as code.
3691 * src/scan-code.h (translate_rule_action):
3692 (translate_symbol_action, translate_code, translate_action): Return
3693 `char const *' rather than `char *' since external code should not free
3694 these strings.
3695 * src/scan-code.l: Likewise.
3696 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
3697 which is "{...}" in the parser.
3698 * tests/Makefile.am (maintainer-check-valgrind): Set
3699 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
3700 Valgrind.
3701 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
3702 complain.
3703 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
3704 expecting a non-zero exit status sets --leak-check=summary and
3705 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
3706 this case, and we don't want to hear about it.
3707
3708 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3709
3710 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
3711 instead of from the template, to simplify configuration a bit.
3712 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
3713 and m4/wint_t.m4, as they are needed with the latest gnulib.
3714
3715 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
3716
3717 Disable unset/unused mid-rule value warnings by default, and recognize
3718 --warnings=midrule-values to enable them. Discussed starting at
3719 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
3720 * NEWS (2.3a+): Mention.
3721 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum
3722 warnings): Add entry for midrule-values subargument.
3723 * src/reader.c (symbol_should_be_used): Don't return true just because
3724 the value is a set/used mid-rule value unless
3725 --warnings=midrule-values was specified.
3726 * tests/input.at (Unused values, Unused values before symbol
3727 declarations): Run tests with and without --warnings=midrule-values.
3728
3729 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
3730 than LIST_FREE directly.
3731
3732 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
3733
3734 Finish implementing --warnings=error, which should not be implied by
3735 --warnings=all (or by its synonyms -W and --warnings without
3736 subarguments).
3737 * src/complain.c (set_warning_issued): New function to report that
3738 warnings are being treated as errors and to record an error if so.
3739 Invoke...
3740 (warn_at, warn): ... here.
3741 * src/getargs.c (warnings_args, warnings_types): Reorder so that
3742 "error - warnings are errors" does not appear above "all - all of the
3743 above".
3744 (getargs): For -W and --warnings without subarguments, don't let
3745 FLAGS_ARGMATCH set warnings_error in warnings_flag.
3746 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
3747
3748 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
3749
3750 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for

3752
3753 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3754
3755 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
3756 the parser header file so that gcc doesn't warn.
3757
3758 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3759
3760 Split the default %destructor/%printer into two kinds: <*> and <!>.
3761 Discussed starting at
3762 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
3763 * NEWS (2.3a+): Mention.
3764 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
3765 previous change today related to mid-rules.
3766 (Table of Symbols): Remove %symbol-default and add <*> and <!>.
3767 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
3768 (TYPE_TAG_ANY): Add as <*>.
3769 (TYPE_TAG_NONE): Add as <!>.
3770 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
3771 for <*> and <!>.
3772 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
3773 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
3774 * src/symlist.c (symbol_list_default_new): Split into tagged and
3775 tagless versions.
3776 (symbol_list_destructor_set, symbol_list_printer_set): Split
3777 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
3778 SYMLIST_DEFAULT_TAGLESS.
3779 * src/symlist.h: Update symbol_list_default*_new prototypes.
3780 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
3781 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
3782 * src/symtab.c (default_destructor, default_destructor_location,
3783 default_printer, default_printer_location): Split each into tagged and
3784 tagless versions.
3785 (symbol_destructor_get, symbol_destructor_location_get,
3786 symbol_printer_get, symbol_printer_location_get): Implement tagged
3787 default and tagless default cases.
3788 (default_destructor_set, default_printer_set): Split each into tagged
3789 and tagless versions.
3790 * src/symtab.h: Update prototypes.
3791 * tests/actions.at (Default %printer and %destructor): Rename to...
3792 (Default tagless %printer and %destructor): ... this, and extend.
3793 (Per-type %printer and %destructor): Rename to...
3794 (Default tagged and per-type %printer and %destructor): ... this, and
3795 extend.
3796 (Default %printer and %destructor for user-defined end token): Extend.
3797 (Default %printer and %destructor are not for error or $undefined):
3798 Update.
3799 (Default %printer and %destructor are not for $accept): Update.
3800 (Default %printer and %destructor for mid-rule values): Extend.
3801 * tests/input.at (Default %printer and %destructor redeclared): Extend.
3802 (Unused values with default %destructor): Extend.
3803
3804 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3805
3806 Don't apply the default %destructor/%printer to an unreferenced midrule
3807 value. Mentioned at
3808 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
3809 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
3810 like $@n instead of just @n so that the default %destructor/%printer
3811 logic doesn't see them as user-defined symbols.
3812 (symbol_is_dummy): Check for both forms of the name.
3813 * src/reader.c (packgram): Remove the `$' from each midrule symbol
3814 name for which the midrule value is referenced in any action.
3815 * tests/actions.at (Default %printer and %destructor for mid-rule
3816 values): New test.
3817 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
3818 for change to dummy symbol names.
3819
3820 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
3821
3822 Warn about unset midrule $$ if the corresponding $n is used.
3823 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
3824 $n usage.
3825 (packgram): Before invoking grammar_rule_check on any rule, make sure
3826 all actions have already been scanned in order to set `used' flags.
3827 Otherwise, checking that a midrule's $$ is set will not always work
3828 properly because the midrule check must forward-reference the midrule's
3829 parent rule.
3830 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
3831 warning.
3832
3833 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
3834
3835 More improvements to the documentation of the prologue alternatives:
3836 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
3837 Bison manual.
3838 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
3839 some text to clarify the relative importance of the new directives and
3840 to show how these directives may be viewed as code labels.
3841
3842 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
3843
3844 Similar to the recently removed %before-header, add %code-top as the
3845 alternative to the pre-prologue. Mentioned at
3846 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
3847 Also, let the prologue alternatives appear in the grammar section.
3848 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
3849 (prologue_declaration): Move the existing prologue alternatives to...
3850 (grammar_declaration): ... here and add %code-top.
3851 * src/scan-gram.l (PERCENT_CODE_TOP): New token.
3852
3853 Clean up and extend documentation for the prologue alternatives.
3854 * NEWS (2.3a+): Describe prologue alternatives.
3855 * doc/bison.texinfo (Prologue): Move discussion of prologue
3856 alternatives to...
3857 (Prologue Alternatives): ... this new section, and extend it to discuss
3858 all 4 directives in detail.
3859 (Table of Symbols): Clean up discussion of prologue alternatives and
3860 add %code-top.

3899 (Sync from coreutils.)
3900 Work also when the working directory (with e.g. coreutils sources)
3901 is version controlled with git, rather than CVS.
3902 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
3903 rather than CVS.
3904 In messages and comments, say e.g., "checked-out sources",

3910 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
3911
3912 Fix testsuite for ./configure --enable-gcc-warnings:
3913 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
3914 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
3915 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
3916 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.

3952
3953 * bootstrap: Sync from coreutils, as follows:
3954
3955 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3956
3957 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
3958 variable was sometimes used without being initialized. This
3959 messed up the installation of the INSTALL file in some cases.
3960
3961 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
3962
3963 * bootstrap (usage, main program, symlink_to_gnulib): Add option
3964 --copy. Inspired by a suggestion from Bruno Haible.
3965
3966 2006-10-03 Jim Meyering <jim@meyering.net>
3967
3968 * bootstrap: Undo last change to this file, since now gnulib-tool
3969 sticks with the automake default in generating dependencies.
3970
3971 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3972
3973 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

3977
3978 * data/glr.c: Don't include <stdarg.h>; not used.
3979
3980 * NEWS: The -g and --graph options now output graphs in Graphviz
3981 DOT format, not VCG format.
3982 * doc/bison.1: Likewise.
3983 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
3984 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
3985 of this change in

4001 Output graphviz format rather than VCG format.
4002 * tests/.cvsignore: Remove *.vcg; add *.dot.
4003 * tests/output.at: Expect *.dot files, not *.vcg files.
4004
4005 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this

4046
4047 Fix test failure reported by Tom Lane in
4048 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
4049 and try to make such failures easier to catch in the future.
4050 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
4051 that's now the caller's responsibility.
4052 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
4053 Set yychar = YYEOF if it's negative.
4054 * tests/actions.at (yylex): Abort if asked to read past EOF.

4114
4115 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
4116
4117 * bootstrap (symlink_to_gnulib): New function.
4118 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
4119 to copies-of-gnulib.

4153 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
4154 use the unistd module.
4155 * src/system.h: Likewise.
4156 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
4157 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
4158 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
4159 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
4160 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
4161 * src/system.h: Include inttypes.h unconditionally, now that we
4162 use the inttypes module. Don't bother to include stdint.h, since
4163 inttypes.h now does that for us.
4164 (LOCALEDIR): Remove, now that we use the configmake module.
4165 * src/getargs.c: Include configmake.h.
4166 * src/main.c: Likewise.
4167 * src/output.c: Likewise.
4168 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
4169 not from $abs_top_builddir, since config.h moved.
4170
4171
4172 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
4173 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4174
4175 * src/parse-gram.y (symbol_declaration): Don't put statements
4176 before declarations; it's not portable to C89.
4177 * src/scan-code.l (handle_action_at): Likewise.
4178
4179 * src/scan-code.l: Always initialize braces_level; the old code
4180 left it uninitialized and therefore had undefined behavior.
4181
4182 Don't attempt to redefine 'assert', since it runs afoul of
4183 systems where standard headers (mistakenly) include <assert.h>.
4184 Instead, define and use our own alternative, called 'aver'.
4185 * src/reader.c: Don't include assert.h, since we no longer
4186 use assert.
4187 * src/scan-code.l: Likewise.
4188 * src/system.h (assert): Remove, replacing with....
4189 (aver): New function, taking a bool arg. All uses changed.
4190 * src/tables.c (pack_vector): Ensure that aver arg is bool,
4191 not merely an integer.
4192
4193 2006-09-15 Bob Rossi <bob@brasko.net>
4194
4195 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
4196 * data/c.m4 (YYPUSH): New.
4197 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
4198 * src/getargs.c (push_parser): New var.
4199 * src/getargs.h (push_parser): New declaration.
4200 * src/output.c (prepare): Add macro insertion of `push_flag'.
4201 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
4202 (prologue_declaration): Parse %push-parser.
4203 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
4204 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
4205 list of removed lines from the traces observed.
4206 (AT_CHECK_CALC_LALR): Added push parser tests.
4207
4208 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
4209
4210 * NEWS: Version 2.3a.
4211 * configure.ac (AC_INIT): Likewise.
4212
4213 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
4214 "#define YYSTYPE int" that caused "make maintainer-check" to fail
4215 due to header ordering dependencies. I don't know why the #define
4216 was there.
4217
4218 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4219 runtime cost when YYDEBUG is not defined, and so that some tests
4220 that used to fail now work. Problem and initial suggestion by
4221 Paolo Bonzini.
4222 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
4223 * data/glr.cc (b4_parser_class_name):
4224 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
4225 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
4226 (yydebug_) [YYDEBUG]: New member.
4227 (yycdebug_): Now defined only if YYDEBUG.
4228 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
4229 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
4230 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
4231 if YYYDEBUG.
4232 (debug_stream, set_debug_stream, debug_level, set_debug_level):
4233 Define only if YYDEBUG.
4234 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
4235 set_debug_level.
4236 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
4237 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
4238 AT_CHECK_CALC_GLR_CC that are working now.
4239
4240 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4241
4242 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
4243 We don't need them in glr.cc, and glr.c defines them.
4244 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
4245 assumes that defining it to anything is the same as defining
4246 it to 1. Problem reported by Paolo Bonzini.
4247
4248 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
4249
4250 * data/c.m4 (b4_null, b4_case): Define.
4251 * src/output.c (prepare_symbols): Use b4_null.
4252 (user_actions_output): Use b4_case.
4253
4254 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
4255
4256 * data/glr.c (b4_shared_declarations): Put start-header first,
4257 before any #includes that we generate, so that feature-test
4258 macros work. Problem reported by Michael Deutschmann in
4259 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
4260 * data/lalr1.cc: Likewise.
4261 * doc/bison.texinfo (Prologue): Document that feature-test macros
4262 should be defined before any Bison declarations.
4263 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
4264 that depend on location.hh after, not before, Bison decls, since
4265 we now include location.hh after the first user prologue.
4266
4267 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
4268 Sander Brandenburg in
4269 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
4270 Also, fix minor white space and comment issues.
4271 (Prologue): Mention that it's better to define feature-test macros
4272 before Bison declarations. Problem reported by Michael Deutschmann.
4273
4274 * README-cvs: Fix typo: "&" should be "&&". Problem reported
4275 by Jim Meyering.
4276 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
4277 This adjusts to recent gnulib changes.
4278
4279 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4280
4281 Finish implementation of per-type %destructor/%printer. Discussed
4282 starting at
4283 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
4284 and
4285 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
4286 * NEWS (2.3+): Add a description of this feature to the default
4287 %destructor/%printer description.
4288 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
4289 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4290 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
4291 list node contains a semantic type.
4292 * src/symtab.c, src/symtab.h: Extend with a table that associates
4293 semantic types with their %destructor's and %printer's.
4294 (semantic_type_from_uniqstr, semantic_type_get,
4295 semantic_type_destructor_set, semantic_type_printer_set): New functions
4296 composing the public interface of that table.
4297 (symbol_destructor_get, symbol_destructor_location_get,
4298 symbol_printer_get, symbol_printer_location_get): If there's no
4299 per-symbol %destructor/%printer, look up the per-type before trying
4300 the default.
4301 * tests/actions.at (Per-type %printer and %destructor): New test case.
4302 * tests/input.at (Default %printer and %destructor redeclared):
4303 Extend to check that multiple occurrences of %symbol-default in a
4304 single %destructor/%printer declaration is an error.
4305 (Per-type %printer and %destructor redeclared, Unused values with
4306 per-type %destructor): New test cases.
4307
4308 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4309
4310 Require default %destructor/%printer to be declared using
4311 %symbol-default instead of an empty symbol list, and start working on
4312 new per-type %destructor/%printer. Discussed at
4313 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
4314 * NEWS (2.3+): Add %symbol-default to example.
4315 * bison.texinfo (Freeing Discarded Symbols): Likewise.
4316 (Table of Symbols): Add entry for %symbol-default.
4317 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
4318 (generic_symlist, generic_symlist_item): New nonterminals for creating
4319 a list in which each item is a symbol, semantic type, or
4320 %symbol-default.
4321 (grammar_declaration): Use generic_symlist in %destructor and %printer
4322 declarations instead of symbols.1 or an empty list.
4323 (symbol_declaration, precedence_declaration, symbols.1): Update actions
4324 for changes to symbol_list.
4325 * src/reader.c: Update for changes to symbol_list.
4326 * src/scan-code.l: Likewise.
4327 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
4328 * src/symlist.c, src/symlist.h: Extend such that a list node may
4329 represent a semantic type or a %symbol-default in addition to just an
4330 ordinary symbol. Add switched functions for setting %destructor's and
4331 %printer's.
4332 * tests/actions.at, tests/input.at: Add %symbol-default to all default
4333 %destructor/%printer declarations.
4334
4335 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
4336
4337 Whether the default %destructor/%printer applies to a particular symbol
4338 isn't a question of whether the user *declares* that symbol (in %token,
4339 for example). It's a question of whether the user by any means
4340 *defines* the symbol at all (by simply using a char token, for
4341 example). $end is defined by Bison whereas any other token with token
4342 number 0 is defined by the user. The error token is always defined by
4343 Bison regardless of whether the user declares it with %token, but we
4344 may one day let the user define error as a nonterminal instead.
4345 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4346 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4347 the meaning of "user-defined".
4348 * tests/actions.at (Default %printer and %destructor for user-declared
4349 end token): Rename to...
4350 (Default %printer and %destructor for user-defined end token): ...
4351 this.
4352
4353 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4354 computation of whether to apply the default, don't maintain a list of
4355 every Bison-defined symbol. Instead, just check for a first character
4356 of '$', which a user symbol cannot have, and check for the error token.
4357
4358 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
4359
4360 Don't apply the default %destructor or %printer to the error token,
4361 $undefined, or $accept. This change fits the general rule that the
4362 default %destructor and %printer are only for user-declared symbols,
4363 and it solves several difficulties that are described in the new test
4364 cases listed below.
4365 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
4366 * tests/actions.at (Default %printer and %destructor are not for error
4367 or $undefined, Default %printer and %destructor are not for $accept):
4368 New test cases.
4369
4370 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
4371
4372 Allow %start after the first rule.
4373 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
4374 when parsing the first rule.
4375 (check_and_convert_grammar): Search for it here after all grammar
4376 declarations have been parsed. Skip midrules, which have dummy LHS
4377 nonterminals.
4378 * src/symtab.c (symbol_is_dummy): New function.
4379 * src/symtab.h (symbol_is_dummy): Declare it.
4380 * tests/input.at (%start after first rule): New test.
4381
4382 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4383
4384 Redo some of the previous commit: add back the ability to use
4385 non-aliased/undeclared string literals since it might be useful to
4386 those declaring %token-table.
4387 * src/reader.c (check_and_convert_grammar): Undo changes in previous
4388 commit: don't worry about complaints from symbols_pack.
4389 * src/symtab.c (symbol_new, symbol_class_set,
4390 symbol_check_alias_consistency): Undo changes in previous commit: count
4391 each string literal as a new symbol and token, assign it a symbol
4392 number, and don't complain about non-aliased string literals.
4393 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4394 and token counts but does still set aliased tokens to the same number,
4395 symbol_pack_processor now leaves empty slots in the symbols array.
4396 Remove those slots.
4397 * tests/regression.at (Undeclared string literal): Remove test case
4398 added in previous commit since non-aliased string literals are allowed
4399 again.
4400 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
4401 remove unnecessary string literal declarations.
4402 * tests/sets.at (Firsts): Likewise.
4403
4404 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4405
4406 Don't allow an undeclared string literal, but allow a string literal to
4407 be used before its declaration.
4408 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
4409 symbols_pack complained.
4410 * src/symtab.c (symbol_new): Don't count a string literal as a new
4411 symbol.
4412 (symbol_class_set): Don't count a string literal as a new token, and
4413 don't assign it a symbol number since symbol_make_alias does that.
4414 (symbol_make_alias): It's not necessary to decrement the symbol and
4415 token counts anymore. Don't assume that an alias declaration occurs
4416 before any uses of the identifier or string, and thus don't assert that
4417 one of them has the highest symbol number so far.
4418 (symbol_check_alias_consistency): Complain if there's a string literal
4419 that wasn't declared as an alias.
4420 (symbols_pack): Bail if symbol_check_alias_consistency failed since
4421 symbol_pack asserts that every token has been assigned a symbol number
4422 although undeclared string literals have not.
4423 * tests/regression.at (String alias declared after use, Undeclared
4424 string literal): New test cases.
4425 (Characters Escapes, Web2c Actions): Declare string literals as
4426 aliases.
4427 * tests/sets.at (Firsts): Likewise.
4428
4429 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
4430
4431 In the grammar scanner, STRING_FINISH unclosed constructs and return
4432 them to the parser in order to improve error messages.
4433 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
4434 SC_BRACED_CODE, SC_PROLOGUE): Implement.
4435 * tests/input.at (Unclosed constructs): New test case.
4436 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
4437 seen.
4438
4439 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
4440 unused global.
4441
4442 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
4443
4444 Handle string aliases for character tokens correctly.
4445 * src/symtab.c (symbol_user_token_number_set): If the token has an
4446 alias, check and set its alias's user token number instead of its own,
4447 which is set to indicate the alias. Previously, every occurrence of
4448 the character token in the grammar overwrote that alias indicator with
4449 the character code.
4450 * tests/input.at (String aliases for character tokens): New test.
4451
4452 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
4453
4454 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
4455
4456 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
4457
4458 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
4459 to prevent failures when building on older platforms.
4460 Check for autopoint failure.
4461 Set XGETTEXT_OPTIONS to values that check for C format strings,
4462 so that translators are warned about them (this also helps
4463 prevent core dumps).
4464
4465 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
4466 function, since it simplifies our code a bit.
4467
4468 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
4469 rather than -W, so we don't get bogus warnings about sign comparisons.
4470 Add -Wpointer-arith, since that warning is useful (it reports code
4471 that does not conform to C89 and that some compilers reject).
4472 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
4473 since it's no longer needed.
4474
4475 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
4476
4477 Clean up scanners a bit.
4478 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
4479 definitions so gcc won't warn when obstack_for_string is unused.
4480 * src/scan-code.l: config.h and system.h are already #include'd by
4481 scan-code-c.c, so get rid of them here.
4482 * src/scan-gram.l: Likewise.
4483 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
4484 definitions rather than duplicating the rest of it.
4485 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
4486
4487 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
4488
4489 Suppress signed/unsigned comparison warnings for yycheck.
4490 * data/c.m4 (b4_safest_int_type): New macro.
4491 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
4492 a signed int type, cast it to b4_safest_int_type first.
4493 * data/yacc.c: Likewise.
4494 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
4495 also overwritten.
4496
4497 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
4498
4499 * doc/bison.texinfo: Fix some typos.
4500
4501 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
4502
4503 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
4504 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
4505
4506 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
4507 the latest gnulib does this a different way.
4508 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
4509 translation was patched, so stop omitting it.
4510
4511 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4512
4513 Enable declaration of default %printer/%destructor. Make the parser
4514 use these for all user-declared grammar symbols for which the user does
4515 not declare a specific %printer/%destructor. Thus, the parser uses it
4516 for token 0 if the user declares it but not if Bison generates it as
4517 $end. Discussed starting at
4518 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
4519 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
4520 and
4521 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
4522 * NEWS (2.3+): Mention.
4523 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4524 declare a %destructor for a mid-rule's semantic value. It's just
4525 impossible to declare one specific to it.
4526 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
4527 code. Describe default %destructor form.
4528 * src/parse-gram.y (grammar_declaration): Parse default
4529 %printer/%destructor declarations.
4530 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
4531 and symbol_destructor_location_get rather than accessing the destructor
4532 and destructor_location members of struct symbol.
4533 (symbol_printers_output): Likewise but for %printer's.
4534 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
4535 again.
4536 * src/symtab.c (default_destructor, default_destructor_location,
4537 default_printer, default_printer_location): New static global
4538 variables to record the default %destructor and %printer.
4539 (symbol_destructor_get, symbol_destructor_location_get,
4540 symbol_printer_get, symbol_printer_location_get): New functions to
4541 compute the appropriate %destructor and %printer for a symbol.
4542 (default_destructor_set, default_printer_set): New functions to set the
4543 default %destructor and %printer.
4544 * src/symtab.h: Prototype all those new functions.
4545 * tests/actions.at (Default %printer and %destructor): New test to
4546 check that the right %printer and %destructor are called, that they're
4547 not called for $end, and that $$ and @$ work correctly.
4548 (Default %printer and %destructor for user-declared end token): New
4549 test to check that the default %printer and %destructor are called for
4550 a user-declared end token.
4551 * tests/input.at (Default %printer and %destructor redeclared, Unused
4552 values with default %destructor): New tests to check related grammar
4553 warnings and errors.
4554
4555 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4556
4557 Clean up handling of %destructor for the end token (token 0).
4558 Discussed starting at
4559 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
4560 and
4561 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
4562
4563 Make the skeletons consistent in how they pop the end token and invoke
4564 its %destructor.
4565 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4566 state, which has token number 0, since this would invoke the
4567 %destructor for the end token.
4568 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
4569 until after shifting the end token, or else it won't be popped.
4570 * data/yacc.c (yyparse): Likewise.
4571
4572 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
4573 it's the end token. Upon termination, destroy an unshifted lookahead
4574 even when it's the end token.
4575 * data/lalr1.cc (yy::parser::parse): Likewise.
4576 * data/yacc.c (yyparse): Likewise.
4577
4578 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
4579 value warnings for the end token when the user gives the end token a
4580 %destructor.
4581
4582 * tests/actions.at (Printers and Destructors): Test all the above.
4583
4584 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4585
4586 Update to latest gnulib and gettext versions.
4587 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
4588 Add fopen-safer.
4589 (gnulib_files): Add m4/warning.m4. Don't worry about files
4590 overwritten by autopoint.
4591 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
4592 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
4593 rejects them.
4594 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4595 so that we can remove the intl files at a better time.
4596 (intl_files_to_remove): Remove aclocal.m4, since it gets
4597 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
4598 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
4599 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
4600 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
4601 Remove datarootdir hack; no longer needed.
4602 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
4603 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
4604 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
4605 strdup.h.
4606 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
4607 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
4608
4609 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4610
4611 * bootstrap: Adjust to today's change to gnulib-tool by invoking
4612 it with --assume-autoconf='latest-stable'.
4613
4614 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
4615
4616 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
4617 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
4618 YYSTYPE' and `{'.
4619 * src/muscle_tab.h (muscle_grow): Replace the header comments with
4620 those from muscle_tab.c since the old ones are misleading.
4621
4622 2006-07-13 Akim Demaille <akim@epita.fr>
4623
4624 Support %define "KEY" {VALUE}.
4625 * src/scan-code.h, src/scan-code.l (translate_action)
4626 (translate_rule_action, translate_symbol_action, translate_code):
4627 Return char *, not const char *.
4628 * src/parse-gram.y (declaration): Rename as...
4629 (prologue_declaration): this.
4630 (string_content): Remove this nonterminal, use STRING.
4631 (braceless, content, content.opt): New nonterminal.
4632 Use them.
4633 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
4634 as value.
4635 * src/scan-gram.l (getargs.h): Don't include it.
4636
4637 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
4638
4639 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
4640 rather than a for-loop that declares a local bool variable. This
4641 should work around a compatibility problem with a Cray x1e C++
4642 compiler reported by Hung Nguyen in
4643 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
4644 The for-loop was introduced in the 2004-11-17 change but I don't
4645 know why it was needed.
4646
4647 2006-07-12 Akim Demaille <akim@epita.fr>
4648
4649 * data/c.m4: Comment changes.
4650
4651 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
4652
4653 * src/complain.c (error_message, ERROR_MESSAGE): New.
4654 To factor...
4655 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
4656 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
4657
4658 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4659
4660 * NEWS: Instead of %union, you can define and use your own union type
4661 YYSTYPE if your grammar contains at least one <type> tag.
4662 Your YYSTYPE need not be a macro; it can be a typedef.
4663 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
4664 (Union Decl, Decl Summary): Document this.
4665 * data/glr.c (YYSTYPE): Implement this.
4666 * data/glr.cc (YYSTYPE): Likewise.
4667 * data/lalr1.cc (YYSTYPE): Likewise.
4668 * data/yacc.c (YYSTYPE): Likewise.
4669 * src/output.c (prepare): Output tag_seen_flag.
4670 * src/parse-gram.y (declaration, grammar_declaration):
4671 Use 'union_seen' rather than 'typed' to determine whether
4672 %union has been seen, since grammars can now be typed without
4673 %union.
4674 (symbol_declaration, type.opt, symbol_def):
4675 Keep track of whether a tag has been seen.
4676 * src/reader.c (union_seen, tag_seen): New vars.
4677 (typed): remove.
4678 * src/reader.h (union_seen, tag_seen, typed): Likewise.
4679 * src/scan-code.l (untyped_var_seen): New variable.
4680 (handle_action_dollar): Adjust to above changes.
4681 (handle_action_dollar, handle_action_at):
4682 Improve overflow checking for outlandish numbers.
4683 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
4684 avoid new diagnostics generated by above changes.
4685 * tests/regression.at (YYSTYPE typedef): Add test to check
4686 for type tags without %union.
4687
4688 * src/symlist.c (symbol_list_length): Return int, not unsigned
4689 int, since callers expect int. This may need to get revisited
4690 once we have proper integer overflow checking.
4691
4692 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
4693 object is now static.
4694
4695 * src/getargs.c (flags_argmatch): Return void, not int,
4696 to pacify ./configure --enable-gcc-warnings.
4697
4698 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
4699 since last_string is already defined to FLEX_PREFIX (last_string).
4700
4701 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4702
4703 Implement --warnings/-W.
4704 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
4705 replaced by...
4706 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
4707 Adjust callers.
4708 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
4709 (warnings_args, warnings_types): New.
4710 (getargs, short_options, long_options): Accept -W/--warnings.
4711 Sort the options by alphabetical order, upper case letter right
4712 before its lower case.
4713
4714 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4715
4716 Change %merge result type clash warnings to errors. Discussed at
4717 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
4718 * src/reader.c (record_merge_function_type): Use complain_at.
4719 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4720 declared later): Update test case results.
4721
4722 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4723
4724 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
4725 to be in alphabetical order.
4726 (trace_args): Spelling fixes.
4727
4728 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4729
4730 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
4731 so they don't collide with user-defined macros.
4732 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4733 this was never guaranteed, and now that we're using gnulib stdint,
4734 which defines int_fast16_t to long int, the problem is exposed.
4735
4736 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
4737
4738 * data/c.m4 (b4_basename): Simplify a bit, since we don't
4739 need the full POSIX semantics (and weren't implementing them
4740 anyway).
4741
4742 Adjust to Autoconf 2.60 and today's gnulib.
4743 * bootstrap (gnulib_modules): Add stdint.
4744 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4745 no longer copies it.
4746 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4747 since stdint needs the former and wcwidth (which is now required
4748 by mbswidth) needs the latter.
4749 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4750 work around a compatibility glitch between gettext 0.14.6 and
4751 Autoconf 2.60.
4752 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
4753 Do not check for uintptr_t, since new stdint module does the right
4754 thing.
4755 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
4756 Add stdint.h, stdint_.h, wcwidth.h.
4757 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
4758 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
4759 stdint.m4, wchar_t.m4, wcwidth.m4.
4760 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
4761 usual order for ../lib/*.h files.
4762 (file_name_split): Use last_component, not base_name, to adjust
4763 to gnulib changes.
4764 * src/parse-gram.h: Include <strverscmp.h> in the usual order
4765 for ../lib/*.h files.
4766 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
4767 Define unconditionally, since we now assume the stdint module.
4768 * src/scan-skel.l: Include <dirname.h>.
4769 (BASE_QPUTS): Use last_component, not base_name.
4770 * src/system.h: Include <unlocked-io.h> in the usual order
4771 for ../lib/*.h files. Include <stdint.h> unconditionally,
4772 since we now use the stdint module.
4773 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
4774 HAVE_UINTPTR_T, since we now use the stdint module.
4775 (base_name): Remove decl, since files now include <dirname.h>
4776 to get the decl.
4777
4778 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4779
4780 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
4781 New, default to 1.
4782 * data/yacc.c, data/glr.c, data/location.cc: Use them.
4783 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
4784 default.
4785 * tests/calc.at: Adjust.
4786
4787 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4788
4789 * data/c.m4 (b4_basename): New.
4790 (b4_syncline): Also output the location of its invocation (from
4791 the skeleton).
4792 (b4_user_action, b4_define_user_action, b4_user_actions)
4793 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
4794 (b4_user_stype): New.
4795 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
4796
4797 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4798
4799 In the grammar file, the first column is 1 not 0 on the first line as
4800 on every other line.
4801 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
4802 * tests/input.at (Torturing the Scanner): Update output.
4803
4804 * src/scan-gram.l (scanner_cursor): Declare it static.
4805
4806 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4807
4808 In warnings, say "previous declaration" rather than "first
4809 declaration".
4810 * src/symtab.c (redeclaration): Do that here.
4811 * src/reader.c (record_merge_function_type): In the case of a result
4812 type clash, report the previous declaration rather than the very first
4813 one in the grammar file.
4814 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4815 declared later): Add a third declaration to check this behavior.
4816 * tests/input.at (Incompatible Aliases): Update output.
4817
4818 2006-06-27 Akim Demaille <akim@epita.fr>
4819
4820 * doc/Doxyfile.in: New.
4821 * doc/Makefile.am: Use it.
4822 * src/lalr.h, src/symtab.h: Initial doxygenation.
4823
4824 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4825
4826 Don't miss %merge result type warnings just because the LHS types are
4827 declared after the %merge. This continues the effort of the previous
4828 patch.
4829 * src/reader.c (get_merge_function): Don't set the merger type yet.
4830 (record_merge_function_type): New function for setting the merger type
4831 and checking for clashes.
4832 (grammar_current_rule_merge_set): Set the location of the %merge for
4833 the current rule.
4834 (packgram): Invoke record_merge_function_type for each rule now that
4835 all symbol type declarations have been parsed.
4836 * src/reader.h (merger_list.type_declaration_location): New member
4837 storing the location of the first %merge from which the type for this
4838 merging function was derived.
4839 * src/symlist.h (symbol_list.merger_declaration_location): New member
4840 storing the location of a rule's %merge, if any.
4841 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4842 declared later): New test to catch the error fixed by the above patch.
4843
4844 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4845
4846 Get action warnings (grammar_rule_check) right even when symbol
4847 declarations appear after the rules. Discussed at
4848 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
4849 and
4850 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
4851 Don't mistake the type of $$ in a midrule to be that of its parent
4852 rule's $$.
4853 * src/reader.c (grammar_current_rule_end): Don't invoke
4854 grammar_rule_check yet since not all symbol declarations may have been
4855 parsed yet.
4856 (grammar_midrule_action): Likewise.
4857 Don't record whether the midrule's $$ has been used yet since actions
4858 haven't been translated yet.
4859 Record the midrule's parent rule and its RHS index within the parent
4860 rule.
4861 (grammar_current_rule_action_append): Don't translate the action yet
4862 since not all symbol declarations may have been parsed yet and, thus,
4863 warnings about types for $$, $n, @$, and @n can't be reported yet.
4864 (packgram): Translate the action and invoke grammar_rule_check now that
4865 all symbol declarations have been parsed.
4866 * src/scan-code.l (handle_action_dollar): Now that this is invoked
4867 after parsing the entire grammar file, the symbol list here in the case
4868 of a midrule is actually the midrule's empty RHS, so reference its
4869 parent rule's RHS where necessary.
4870 On the other hand, now that you can already know it's a midrule, you
4871 aren't forced to think $$ has the same type as its parent rule's $$.
4872 (handle_action_at): In the case of a midrule, reference the parent rule
4873 where necessary.
4874 * src/symlist.c (symbol_list_new): Initialize new midrule-related
4875 members.
4876 (symbol_list_length): Now that this is invoked after all rules have
4877 been parsed, a NULL symbol (rather than a NULL symbol list node)
4878 terminates a rule. symbol_list_print already does this correctly.
4879 * src/symlist.h (symbol_list.midrule_parent_rule,
4880 symbol_list.midrule_parent_rhs_index): New members so that midrules can
4881 remember their relationships with their parents.
4882 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
4883 fixed by the above patch.
4884 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
4885 implementing...
4886 (Unused values): ... this old test case and...
4887 (Unused values before symbol declarations): ... this new test case.
4888 This one is the same as `Unused values' except that all symbol
4889 declarations appear after the rules in order to catch the rest of the
4890 errors fixed by the above patch.
4891
4892 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4893
4894 More cleanup.
4895 * src/reader.c (current_rule): Declare it static since it's no longer
4896 used outside this file.
4897 (grammar_current_rule_action_append): Remove redundant arguments from
4898 translate_rule_action invocation.
4899 * src/reader.h (current_rule): Remove this unused extern.
4900 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
4901 * src/scan-code.l (translate_rule_action): Likewise.
4902
4903 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
4904
4905 Clean up yesterday's patch.
4906 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
4907 to...
4908 * src/reader.c (grammar_current_rule_action_append): ... here for
4909 consistency with grammar_current_rule_symbol_append.
4910 * tests/regression.at (Braced code in declaration in rules section):
4911 Make yyerror and yylex static as usual.
4912
4913 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
4914
4915 Fix bug that mistakes braced code in a declaration in the rules section
4916 to be a rule action. Mentioned at
4917 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
4918 * src/scan-gram.l: Move midrule action detection from the start of the
4919 scanning of any braced code to...
4920 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
4921 action. For readability, use $2 and @2 rather than the equivalent
4922 global variables.
4923 * tests/regression.at (Braced code in declaration in rules section):
4924 New test to catch the error fixed by the above patch.
4925
4926 Work on code readability some.
4927 * src/scan-code.l (current_rule): Get rid of this misleading and
4928 redundant declaration: it's actually extern'ed in reader.h.
4929 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
4930 translate_action): Add a rule argument and use it instead of the global
4931 current_rule.
4932 (translate_rule_action): This already receives current_rule through an
4933 argument, so pass it on to translate_action instead of assigning
4934 current_rule to current_rule.
4935 (translate_symbol_action, translate_code): Pass rule = NULL to
4936 translate_action.
4937
4938 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
4939
4940 Rename %before-definitions to %start-header and %after-definitions to
4941 %end-header. Don't use these declarations to separate pre-prologue
4942 blocks from post-prologue blocks. Add new order-independent
4943 declarations %before-header and %after-header as alternatives to the
4944 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
4945 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
4946 * NEWS (2.3+): Update for these changes.
4947 * data/glr.c (b4_before_definitions): Update to...
4948 (b4_start_header): ... this.
4949 (b4_after_definitions): Update to...
4950 (b4_end_header): ... this.
4951 * data/glr.cc: Likewise.
4952 * data/lalr1.cc: Likewise.
4953 * data/yacc.c: Likewise.
4954 * doc/bison.texinfo (The prologue): Update names, and replace remaining
4955 prologue blocks with %*-header declarations.
4956 (Calc++ Parser): Likewise.
4957 (Decl Summary): Update names.
4958 (Table of Symbols): Update description.
4959 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...

4964 (declaration): Update token names and m4 macro names.
4965 When parsing %end-header and %start-header, invoke translate_code
4966 before muscle_code_grow, and no longer set global booleans to remember
4967 whether these declarations have been seen.
4968 Parse new %after-header and %before-header.
4969 * src/reader.c (before_definitions, after_definitions): Remove.
4970 (prologue_augment): Accept a new bool argument to specify whether to
4971 augment the pre-prologue or post-prologue.

4983
4984 Add comparison operators for C++ location classes. Discussed at
4985 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
4986 * data/c++.m4 (b4_define_location_comparison): New boolean %define
4987 declaration indicating whether filename_type has an operator==. If
4988 filename_type is `std::string', it defaults to `1', `0' otherwise.
4989 * data/location.cc: Iff b4_define_location_comparison is `1', add
4990 operator== and operator!= for class position and for class location.
4991
4992 Some minor fixes.

5001 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
5002
5003 Don't put the pre-prologue in the header file. For the yacc.c code
5004 file and the glr.c header and code files, move the pre-prologue before
5005 the token definitions. Add new %before-definitions and
5006 %after-definitions to declare code that will go in both the header file
5007 and code file. Discussed at
5008 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
5009 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
5010 and
5011 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
5012 * NEWS (2.3+): Describe these changes.
5013 * data/glr.c (b4_pre_prologue): Move from within to before...
5014 (b4_shared_declarations): ... this.

5016 Add new b4_after_definitions at the end.
5017 * data/glr.cc (b4_pre_prologue): Replace with...
5018 (b4_before_definitions): ... this in the header file.
5019 (b4_after_definitions): New near the end of the header file.
5020 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5021 code file right before including the header file.
5022 (b4_before_definitions): New in the previous position of
5023 b4_pre_prologue in the header file.
5024 (b4_after_definitions): New near the end of the header file.
5025 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5026 (b4_token_enums_defines): In the code file, move to right before
5027 YYSTYPE for consistency with the header file.
5028 (b4_before_definitions): New right before b4_token_enums_defines in
5029 both the header and code file.
5030 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5031 header and code file.
5032 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5033 of prologues for %union dependencies.
5034 (Decl Summary): In %defines description, mention the effect of
5035 %before-definitions and %after-definitions on the header file.
5036 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5037 than in the pre-prologue so that make check succeeds.
5038 (Table of Symbols): Add entries for %before-definitions and
5039 %after-definitions.
5040 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5041 %before-definitions.
5042 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5043 (declaration): Parse those declarations and append to
5044 b4_before_definitions and b4_after_definitions, respectively.
5045 * src/reader.c (before_definitions, after_definitions): New bools to
5046 track whether those declarations have been seen.
5047 (prologue_augment): Add to the post-prologue if %union,
5048 %before-definitions, or %after-definitions has been seen.
5049 * src/reader.h (before_definitions, after_definitions): New extern's.
5050 * src/scan-gram.l: Scan the new declarations.
5051 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5052 prologue block in a %before-definitions or a %after-definitions based
5053 on whether the %union is declared.
5054 * tests/regression.at (Early token definitions with --yacc, Early token
5055 definitions without --yacc): Move tests for token definitions into the
5056 post-prologue since token names are no longer defined in the
5057 pre-prologue.
5058
5059 2006-06-20 Akim Demaille <akim@epita.fr>
5060
5061 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5062 (symbol_get): Use it.
5063 * src/parse-gram.y: Use it.
5064
5065 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5066
5067 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5068 build succeeds when configured with --enable-gcc-warnings.
5069
5070 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5071
5072 * src/parse-gram.y (char_name): New function.
5073 (CHAR, STRING, string_content): For %printer, properly escape.
5074 (ID): Prefer fputs to fprintf.
5075 (id): Reindent to be consistent with other rules.
5076 Properly quote char.
5077
5078 The Translation Project changed its way of publishing translations
5079 to maintainers. I haven't received any responses to my request
5080 for supporting the old way, or for documenting the new way. I
5081 have modified 'bootstrap' to use screen scraping
5082 (in this case, HTML scraping). This is unreliable and inelegant,
5083 but I don't see any better way. Yuck.
5084 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5085 (get_translations): New function, which uses HTML scraping to
5086 deduce locations of latest translations.
5087 Use this function to grab both bison and bison-runtime .po files.
5088 Don't bother priming the pump for the runtime-po domain any more,
5089 as it's now translated better than bison is.
5090
5091 2006-06-19 Akim Demaille <akim@epita.fr>
5092
5093 * src/scan-gram.l: No longer "parse" things after `%union' until
5094 `{'. Rather, return a single "%union" token.
5095 No longer make symbols: return strings, and leave the conversion
5096 to symbols to the parser.
5097 (SC_PRE_CODE, token_type): Remove.
5098 * src/parse-gram.y (%union): New field `character'.
5099 Sort tokens.
5100 (CHAR): New token.
5101 (ID, ID_COLON): Now that the scanner no longer makes them
5102 identifiers, adjust all uses to invoke symbol_get.
5103 (id_colon): New, wraps the conversion from string to symbol.
5104 (%union): Accept a possible union_name.
5105 (symbol): Now can be a char.
5106 * data/c.m4 (b4_union_name): Leave a default value.
5107 * data/glr.c, data/yacc.c: Use it.
5108
5109 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
5110
5111 For associating token numbers with token names for "yacc.c", don't use
5112 #define statements unless `--yacc' is specified; always use enum
5113 yytokentype. Most important discussions start at:
5114 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
5115 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
5116 and
5117 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
5118 * NEWS (2.3+): Mention.
5119 * data/c.m4 (b4_yacc_if): New.
5120 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
5121 token #define's.
5122 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
5123 on token name definitions.
5124 * src/getargs.c (usage): Capitalize `Yacc' in English.
5125 * src/output.c (prepare): Define b4_yacc_flag.
5126 * tests/regression.at (Early token definitions): Test that tokens names
5127 are defined before the pre-prologue not just before the post-prologue.
5128 Remove this test case and copy to...
5129 (Early token definitions with --yacc): ... this to test #define's.
5130 (Early token definitions without --yacc): ... and this to test enums.
5131
5132 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
5133
5134 * NEWS: Reword the post-2.3 change to not be so optimistic about
5135 removing the old "look-ahead" spelling.
5136 Update previous look-ahead/lookahead change reports.
5137 * REFERENCES: look-ahead -> lookahead (since that's
5138 what he actually wrote).
5139 * doc/refcard.tex: look ahead -> lookahead,
5140 look-ahead -> lookahead
5141
5142 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
5143
5144 For consistency, use `lookahead' instead of `look-ahead' or
5145 `look_ahead'. Discussed starting at
5146 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
5147 and then at

5220
5221 * TODO: Add request from Nelson H. F. Beebe to be able to install
5222 Bison without installing the yacc script.
5223
5224 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5225
5226 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
5227 and yytext if they're already #define'd.
5228 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...

5234
5235 Get Bison to build again when configured with --enable-gcc-warnings.
5236 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
5237 missing #include's.
5238 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename

5256
5257 2006-06-06 Akim Demaille <akim@epita.fr>
5258
5259 Extract the parsing of user actions from the grammar scanner.
5260 As a consequence, the relation between the grammar scanner and
5261 parser is much simpler. We can also split "composite tokens" back
5262 into simple tokens.
5263 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
5264 * src/scan-gram.l (add_column_width, adjust_location): Move to and

5278 which is now, again, a separate token.
5279 Adjust all dependencies.
5280 Whereever actions with $ and @ are used, use translate_code.
5281 (action): Remove this nonterminal which is now useless.

5283 (grammar_current_rule_action_append): Use translate_code.
5284 (packgram): Bound check ruleno, itemno, and rule_length.

5295 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
5296 Move these declarations, and...
5297 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
5298 these to...
5299 * src/flex-scanner.h: this new file.
5300 * src/scan-gram.l (rule_length, rule_length_overflow)
5301 (increment_rule_length): Remove.
5302 (last_braced_code_loc): Rename as...
5303 (gram_last_braced_code_loc): this.
5304 Adjust to the changes of the parser.
5305 Move all the handling of $ and @ into...
5306 * src/scan-code.l: here.
5307 * src/scan-gram.l (handle_dollar, handle_at): Remove.
5308 (handle_action_dollar, handle_action_at): Move to...
5309 * src/scan-code.l: here.
5310 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
5311 scan-code.h, scan-code-c.c, scan-gram.h.
5312 (EXTRA_bison_SOURCES): Add scan-code.l.

5320 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5321
5322 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5323 Use Akim's wording from

5325
5326 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5327
5328 Between Bison releases, manually append `+' to the previous Bison
5329 release number, and use that as a signal to automatically print the
5330 ChangeLog's CVS Id keyword from --version. Discussed starting at
5331 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
5332 * ChangeLog: Add Id header.
5333 * configure.ac (AC_INIT): Append `+' to `2.3'.
5334 * src/.cvsignore: Add revision.c.
5335 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5336 (BUILT_SOURCES): Add revision.c.
5337 (revision.c): New target rule. This file defines a new global variable
5338 named revision. It initializes it with either the Id from ChangeLog
5339 or, if VERSION doesn't contain `+', with the empty string.
5340 * src/getargs.c (version): Print the value of revision.
5341 * src/revision.h: Extern revision.

5348 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5349
5350 * data/glr.c (YYRECOVERING): Define to be a function-like macro
5351 with no arguments, not as an object-like macro. This is for
5352 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
5353 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
5354 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
5355 Document this.
5356
5357 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
5358
5359 * src/getargs.c (usage): Back out yesterday's modification of the
5360 --help output so that we don't have to wait for translation before
5361 releasing 2.3.
5362
5363 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5364
5365 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
5366 Problem reported by Akim Demaille.
5367
5368 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5369
5370 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5371
5372 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5373
5374 * data/yacc.c (yy_reduce_print): Omit trailing white space in
5375 generated source code. Problem reported by Frans Englich in
5376 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
5377
5378 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
5379
5380 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5381 shell, not within 'make', so that 'make' by an ordinary builder
5382 (using GNU make) does not worry about configuring gzip. This also
5383 works around a bug reported independently by Keith Thompson and by
5384 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5385 stderr rather than stdout, messing up the build logs.
5386
5387 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5388
5389 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
5390 to make sure that YYID will never be unused. This fixes a 'make
5391 maintainer-check' failure caused by the recent changes to the 'Trivial
5392 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5393 not used.
5394 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
5395
5396 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5397
5398 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5399 state before an empty RHS is always resolved here. Only the location
5400 of that state is guaranteed to be resolved, and that's enough. This
5401 fixes the remaining bug reported by Derek M. Jones in
5402 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5403 * tests/glr-regression.at (Uninitialized location when reporting
5404 ambiguity): Test the above case.
5405 Also, the embedded comments in this test case claim it checks the case
5406 of an empty RHS that has inherited the initial location. However, the
5407 corresponding LHS was already resolved, so yyresolveLocations didn't
5408 actually have reason to modify it. Fix this by forcing
5409 nondeterministic operation at the beginning of the parse.
5410
5411 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5412
5413 * data/c.m4 (b4_yy_symbol_print_generate):
5414 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
5415 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
5416 of the bugs reported today by Derek M Jones in
5417 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5418 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
5419 defined to be a type name without parens or brackets.
5420 (Location Type): Similarly for YYLTYPE.
5421 * tests/regression.at (Trivial grammars): Put in a test for this
5422 bug that will be caught by 'make maintainer-check' (though not,
5423 alas, by 'make check' unless your compiler is picky).
5424
5425 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5426
5427 * NEWS: Version 2.2.
5428 * configure.ac (AC_INIT): Likewise.
5429
5430 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
5431
5432 * data/glr.c (yyreportTree): Make room in yystates for the state
5433 preceding the RHS. This fixes the segmentation fault reported by Derek
5434 M. Jones in
5435 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
5436 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
5437 to the user. Reported for yyreportTree by Derek M. Jones later in the
5438 same thread.
5439 * THANKS: Add Derek M. Jones.
5440 Update my email address.
5441 Fix typo in Steve Murphy's name.
5442
5443 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5444
5445 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
5446 checking against YYLAST that caused the parser to miss a potential
5447 alternative in its diagnostic.
5448 Problem reported by Maria Jose Moron Fernandez in
5449 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
5450 * data/lalr1.cc (yysyntax_error_): Likewise.
5451 * data/yacc.c (yysyntax_error): Likewise.
5452 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
5453 tokens, in case we run into an older C compiler.
5454 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
5455 Use them to check for the off-by-one error fixed above.
5456
5457 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
5458 YYSIZE_T, not size_t.
5459 * tests/regression.at (Trivial grammars): New test, to catch
5460 the error fixed by the above patch.
5461
5462 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5463
5464 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
5465 scheme.
5466 Reported by Steve Murphy.
5467
5468 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5469
5470 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
5471 * data/glr.cc: b4_location_flag is now b4_locations_flag.
5472
5473 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5474
5475 Implement --trace=m4.
5476 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
5477 * src/output.c (output_skeleton): When set, pass -dV to m4.
5478
5479 Factor the handling of flags in m4.
5480 * src/output.c (prepare): Rename the muscle names debug, defines,
5481 error_verbose to debug_flag, defines_flag, error_verbose_flag.
5482 * data/c.m4: Adjust.
5483 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
5484 Use b4_define_flag_if to define other b4_FLAG_if macros.
5485 (b4_location_if): As a consequence, rename as...
5486 (b4_locations_if): this, for consistency.
5487 Adjust all the skeletons.
5488
5489 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5490
5491 * etc/bench.pm: Shorten bench names.
5492
5493 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5494
5495 * src/output.h, src/output.c (error_verbose): Move to...
5496 * src/getargs.h, src/getargs.c: here.
5497 Sort the flags.
5498 Adjust dependencies.
5499
5500 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5501
5502 * data/c.m4 (b4_copyright): Put the special exception for Bison
5503 skeletons here, so we don't have to put it in each skeleton. All
5504 uses changed. Suggested by Akim Demaille. Also, wrap the
5505 copyright notice, in case it is longer than 80 columns. Replace
5506 comma by newline after title.
5507
5508 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5509
5510 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
5511 incompatibility, not a bug. Mention that it wasn't fixed as of
5512 flex 2.5.33.
5513
5514 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5515
5516 * examples/extexi: Enforce the precedence of concatenation over
5517 >>.
5518 Reported by Tommy Nordgren.
5519
5520 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5521
5522 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
5523 with the member "token".
5524 Reported by Martin Nylin.
5525
5526 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
5527
5528 * data/glr.c: Switch to Bison 2.2 special-exception language in
5529 the copyright notice. Use more-regular format for titles and
5530 copyright notices.
5531 * data/glr.cc: Likewise.
5532 * data/location.cc: Likewise.
5533 * data/yacc.cc: Likewise.
5534 * doc/bison.texinfo (Conditions): Document this.
5535 * NEWS: likewise. Upgrade version to 2.2.
5536
5537 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
5538
5539 * data/glr.cc: Remove dead code.
5540
5541 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5542
5543 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
5544 that variable and the line breaks the bootstrap. Problem reported
5545 by Juan M. Guerrero.
5546
5547 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
5548
5549 * doc/bison.texinfo (Multiple start-symbols): New.
5550
5551 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
5552
5553 * etc/README, etc/bench.pl: New.
5554
5555 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
5556
5557 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
5558 rule.
5559 Reported by Mickael Labau.
5560 * tests/input.at (Torturing the Scanner): Test it.
5561
5562 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
5563
5564 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
5565 Problem reported by Bob Rossi.
5566
5567 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
5568
5569 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
5570 and didn't really work.
5571 For the index, use @ifnotinfo, not @iftex.
5572 Minor cleanups of spacing and terminology.
5573
5574 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5575
5576 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
5577 of AT_NAME_PREFIX when %name-prefix is not used.
5578
5579 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5580
5581 Apply --prefix to C++ skeletons too: they change the namespace.
5582 The test suite already exercize these cases.
5583 * data/c++.m4 (b4_namespace): New.
5584 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
5585 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
5586 * data/yacc.c, data/glr.c: Remove a useless `[]'.
5587 * doc/bison.texinfo: Document it.
5588 (Option Cross Key): Use @multitable in all formats. It looks
5589 nicer, even in TeX outputs.
5590 (Rules): Use the same code whatever the output type is.
5591 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
5592 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
5593 * tests/calc.at: Use it, instead of hard coding `yy'.
5594
5595 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5596
5597 * TODO: Remove dead items.
5598
5599 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5600
5601 * doc/FAQ: Remove, merged into...
5602 * doc/bison.texinfo (FAQ): this.
5603 * doc/Makefile.am (EXTRA_DIST): Adjust.
5604
5605 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5606
5607 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
5608 even if empty.
5609 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
5610 * doc/bison.texinfo (Calc++ Scanner): Use it.
5611
5612 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
5613
5614 Fix two nits reported by twlevo, plus one more that I discovered.
5615
5616 * src/assoc.h (assoc_to_string): Give a name to the arg, as
5617 this is the usual Bison style.
5618 * src/location.h (location_print): Likewise.
5619
5620 * src/reader.h (token_name): Likewise.
5621
5622 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
5623
5624 Fix some nits reported by twlevo.
5625 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
5626 and "POSIX". Use more-modern syntax for URLs. Mention C++
5627 and ask for Java. Don't hardwire OS version numbers. Add
5628 copyright notice.
5629 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
5630 * src/conflicts.c (solved_conflicts_obstack): Now static.
5631
5632 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
5633
5634 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
5635 page. Say "you can use it" not "you may use it" as on the web page;
5636 we're describing capabilities not granting permission.
5637
5638 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
5639
5640 * data/glr.c (yyresolveLocations): Rename local variables to avoid
5641 shadowing warnings. Use usual patter for iterating through RHS.
5642 * tests/glr-regression.at
5643 (Uninitialized location when reporting ambiguity):
5644 Modify yylex so that it uses its argument, rather than trying
5645 to rely on ARGSUSED (which doesn't work for gcc with warnings).
5646 const char -> char const.
5647
5648 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
5649 Don't use tabs inside commands; it messes up 'ps'.
5650 Problem reported by twlevo.
5651
5652 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
5653
5654 * tests/glr-regression.at (Uninitialized location when reporting
5655 ambiguity): New test case.
5656 * data/glr.c (yyresolveLocations): New function, which uses
5657 YYLLOC_DEFAULT.
5658 (yyresolveValue): Invoke yyresolveLocations before reporting an
5659 ambiguity.
5660 * doc/bison.texinfo (Default Action for Locations): Note
5661 YYLLOC_DEFAULT's usage for ambiguity locations.
5662 (GLR Semantic Actions): Cross-reference those notes.
5663
5664 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
5665
5666 * tests/glr-regression.at (Leaked semantic values when reporting
5667 ambiguity): Remove unnecessary union and type declarations.
5668 (Leaked lookahead after nondeterministic parse syntax error): New test
5669 case.
5670 * data/glr.c (yyparse): Check for zero stacks remaining before
5671 attempting to shift the lookahead so that you don't lose it.
5672
5673 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5674
5675 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
5676 * tests/glr-regression.at (Leaked semantic values when reporting
5677 ambiguity): New test case.
5678 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
5679 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
5680 now unnecessary yystackp parameter.
5681 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
5682 destructors can be called.
5683
5684 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
5685 in existing testcases.
5686
5687 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5688
5689 Don't leak semantic values for parent RHS when a user action cuts the
5690 parser, and clean up related code a bit.
5691 * tests/glr-regression.at (Leaked merged semantic value if user action
5692 cuts parse): Rename to...
5693 (Leaked semantic values if user action cuts parse): ... this. Add check
5694 for leaked parent RHS values.
5695 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
5696 between an unresolved state (non-empty chain of semantic options) and
5697 an incomplete one (signaled by an empty chain).
5698 (yyresolveStates): Document the interface. Move all manipulation of a
5699 successfully or unsuccessfully resolved yyGLRState to...
5700 (yyresolveValue): ... here so that yyresolveValue always leaves a
5701 yyGLRState with consistent data and thus is easier to understand.
5702 Remove the yyvalp and yylocp parameters since they are always just
5703 taken from the yys parameter. When reporting a discarded merged value
5704 in debugging output, note that it is incompletely merged. Document the
5705 interface.
5706 (yyresolveAction): If resolving any of the RHS states fails, destroy
5707 them all rather than leaking them. Thus, as long as user actions are
5708 written to clean up the RHS correctly, yyresolveAction always cleans up
5709 the RHS of a semantic option. Document the interface.
5710
5711 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
5712
5713 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
5714 led to a segmentation fault in GNU Pascal. Problem reported
5715 by Waldek Hebisch.
5716
5717 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
5718
5719 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
5720 mid-rule action inside a nonterminal symbol in order to declare a
5721 destructor for its semantic value.
5722
5723 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
5724
5725 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !

5727 __cplusplus && ! defined _STDLIB_H && !
5728 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
5729 defined free))]: Include <stdlib.h> rather than rolling our own
5730 declarations of malloc and free, to avoid problems with
5731 incompatible declarations (using 'throw') C++'s stdlib.h. This
5732 should fix Debian bug 340012
5733 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,

5749
5750 * m4/c-working.m4: New file.

5762 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
5763 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
5764 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
5765 messes up because C++ code is compiled in 32-bit mode but linked
5766 in 64-bit mode.

5771
5772 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
5773 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
5774
5775 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
5776 nodist_PROGRAMS, since we don't need to actually compile the
5777 example if we're just doing a plain 'make'. This avoids bothering
5778 the installer unnecessarily about problems due to weird C++
5779 compilers.
5780
5781 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
5782
5783 More portability fixes for problems summarized by Nelson H. F. Beebe.
5784
5785 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
5786 than #include "...", and compile with -I'.'. The old method was
5787 not portable, according to Posix and the C standard, and it does
5788 not work with Sun C 5.7, where previous #line directives affect
5789 the working directory used in later #include "..." directives.

5796
5797 More portability fixes for problems summarized by Nelson H. F. Beebe.
5798
5799 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
5800 '#include <map>' works and that you can apply ++ to iterators.
5801
5802 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
5803
5804 Work around portability problems summarized by Nelson H. F. Beebe in
5805 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
5806
5807 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
5808 that '#include <string>' works.
5809
5810 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
5811 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
5812 "warning: sorry: semantics of inline function static data `const
5813 unsigned char translate_table[262]' are wrong (you'll wind up with
5814 multiple copies)".
5815
5816 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
5817 or, xor to not_, and_, or_, and xor_, respectively. This works
5818 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
5819 random system header somewhere that includes the equivalent of
5820 <iso646.h>.
5821
5822 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
5823 -E" works; it apparently doesn't work with PathScale EKO Compiler
5824 Suite Version 2.0.
5825
5826 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
5827
5828 During deterministic GLR operation, user actions should be able to
5829 influence the parse by changing yychar. To make this easier to fix and
5830 to make glr.c easier to evolve in general, don't maintain yytoken in
5831 parallel with yychar; just compute yytoken when needed.
5832 * tests/glr-regression.at (Incorrect lookahead during deterministic
5833 GLR): Check that setting yychar in a user action has the intended
5834 effect.
5835 * data/glr.c (yyGLRStack): Remove yytokenp member.
5836 (yyclearin): Don't set *yytokenp.
5837 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
5838 yychar rather than *yytokenp to determine the current lookahead.
5839 Compute yytoken locally when needed.
5840 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
5841 point to.
5842
5843 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
5844 after `--report' documentation.
5845
5846 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
5847
5848 * src/parse-gram.y (grammar_declaration): Location of printer
5849 symbol is @1, not list->location. Bug reported by twlevo.
5850 * tests/input.at (Incompatible Aliases): Adjust to above change.
5851
5852 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
5853
5854 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
5855 all the test at once. This makes the output easier to read in the
5856 normal case.
5857
5858 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
5859 got from <http://bro-ids.org/download.html>. The bug is that
5860 when two actions appeared in succession, the second one was
5861 scanned before the first one was added to the grammar rule
5862 as a midrule action. Bison then output the incorrect warning
5863 "parse.y:905.17-906.36: warning: unused value: $3".
5864 * src/parse-gram.y (BRACED_CODE, action): These are no longer
5865 associated with a value.
5866 (rhs): Don't invoke grammar_current_rule_action_append.
5867 (action): Invoke it here instead.
5868 * src/reader.c (grammar_midrule_action): Now extern.
5869 (grammar_current_rule_action_append): Don't invoke
5870 grammar_midrule_action; that is now the scanner's job.
5871 * src/reader.h (last_string, last_braced_code_loc):
5872 (grammar_midrule_action): New decls.
5873 * src/scan-gram.l (last_string): Now extern, sigh.
5874 (last_braced_code_loc): New extern variable.
5875 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
5876 rule already has an action.
5877 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
5878 * tests/input.at (AT_CHECK_UNUSED_VALUES):
5879 Add some tests to check that the above changes fixed the bug.
5880
5881 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
5882
5883 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
5884 All used changed. Check whether the symbol has a destructor,
5885 not whether it is typed.
5886 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
5887 that the values are still reported as unused. All line numbers
5888 adjusted.
5889
5890 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
5891
5892 Work around a bug in bro 0.8, which underparenthesizes its
5893 definition of YYLLOC_DEFAULT.
5894 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
5895 their arguments.
5896 * data/lalr1.cc: Likewise.
5897 * data/yacc.cc: Likewise.
5898
5899 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
5900
5901 Work around a bug in Pike 7.0, and give the Pike folks a
5902 better way to override the usual int widths.
5903 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
5904 user can override the types.
5905 (short): #undef, to work around a bug in Pike 7.0.
5906 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
5907 (union yyalloc.yyss): Use yytype_int16 rather than short.
5908 All uses changed.
5909 (yysigned_char): Remove.
5910 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
5911 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
5912 * tests/regression.at (Web2c Actions): Adjust to above changes.
5913
5914 * src/reader.c (check_and_convert_grammar): New function.
5915 (reader): Close the input file even if something went wrong during
5916 parsing. Minor file descriptor leak reported by twlevo.
5917
5918 * src/assoc.c (assoc_to_string): Use a default: abort (); case
5919 to pacify gcc -Wswitch-default.
5920 * src/scan-gram.l (adjust_location): Use a default: break; case
5921 to pacify gcc -Wswitch-default.
5922 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
5923 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
5924 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
5925 Move these decls to scan-skel.l, since they don't need to be
5926 visible elsewhere.
5927 * src/scan-skel.l: Accept the above decls.
5928 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
5929 is used.
5930
5931 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
5932
5933 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
5934 since we don't want to insist on a version number at the start
5935 of the changelog every time.
5936 * Makefile.maint: Sync from coreutils a bit better.
5937 (sc_trailing_blank): Renamed from sc_trailing_space.
5938 All uses changed.

5988
5989 2006-01-20 Paul Eggert <eggert@cs.ucla.edu>

5993 * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
5994 Put 'default: abort ();' before some other case, to satisfy older
5995 pedantic compilers.

6003 (get_linestyle_str, get_arrowstyle_str): Likewise.
6004 * src/conflicts.c (resolve_sr_conflict):
6005 Use a default case rather than one for the one remaining enum
6006 value, to catch invalid enum values as well.
6007 * src/lalr.c (set_goto_map, map_goto):
6008 Prefer "assert (FOO);" to "if (!FOO) abort ();".

6025
6026 2006-01-19 Paul Eggert <eggert@cs.ucla.edu>
6027
6028 Fix some porting glitches found by Nelson H. F. Beebe.
6029 * lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
6030 compilers that don't understand that abort () does not return.
6031 * src/state.c (transitions_to): Likewise.
6032 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
6033 that '#include <cstdlib>' works.

6035 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
6036 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
6037 for the benefit of some pre-C99 compilers.
6038
6039 * bootstrap: Undo changes to gnulib files that autoreconf made.
6040
6041 Minor fixups to get 'make maintainer-check' to work.
6042 * configure.ac: Don't use -Wnested-externs, as it's incompatible
6043 with the new verify.h implementation.
6044 * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
6045 * data/glr.c (YYUSE): Depend on __GNUC__ as well.

6059 (Incorrect lookahead during deterministic GLR):
6060 (Incorrect lookahead during nondeterministic GLR):
6061 Don't name a local var 'index'; it shadows string.h's 'index'.
6062
6063 2006-01-19 Akim Demaille <akim@epita.fr>
6064
6065 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial
6066 location, not just parts of it.
6067
6068 2006-01-18 Paul Eggert <eggert@cs.ucla.edu>
6069
6070 * NEWS: Document the fact that multiple %unions are now allowed.

6072 * TODO: This feature is now implemented, so remove it from
6073 the wishlist.
6074
6075 * Makefile.maint: Merge with coreutils Makefile.maint.

6080 sc_useless_cpp_parens.
6081 (sc_obsolete_symbols): Check for O_NDELAY.
6082 (sc_dd_max_sym_length): Track coreutils.
6083 (sc_unmarked_diagnostics): Look in all files, not just *.c.
6084 (sc_useless_cpp_parens): New rule.
6085 (news-date-check): Look for version or today's date.
6086 (changelog-check): Don't require version number near head.
6087 (copyright-check): Use current year instead of hardwiring 2005.
6088 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
6089 (announcement): Add --gpg-key-ID.
6090
6091 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
6092 with "file system".
6093
6094 Avoid undefined behavior that addressed just before the start of an
6095 array. Problem reported by twlevo.
6096 * src/reader.c (packgram): Prepend a new sentinel before ritem.
6097 * src/lalr.c (build_relations): Rely on new sentinel.
6098 * src/gram.c (gram_free): Adjust to new sentinel.
6099
6100 2006-01-12 Joel E. Denny <jdenny@ces.clemson.edu>
6101
6102 * data/glr.c (yyGLRStateSet): Rename yylookaheadStatuses to
6103 yylookaheadNeeds. All uses updated.

6105 yynewLookaheadNeeds.
6106 * data/glr-regression.at (Incorrect lookahead during nondeterministic
6107 GLR): In comments, change `lookahead status' to `lookahead need'.
6108
6109 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
6110
6111 * data/glr.c (yysplitStack): A little stylistic rewrite.
6112
6113 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
6114
6115 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
6116
6117 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
6118
6119 * doc/bison.texinfo: Fix some typos.
6120 (GLR Semantic Actions): New subsection discussing special
6121 considerations because GLR semantic actions might be deferred.
6122 (Actions): Mention look-ahead usage of yylval.
6123 (Actions and Locations): Mention look-ahead usage of yylloc.
6124 (Special Features for Use in Actions): Add YYEOF entry and mention it
6125 in the yychar entry.
6126 In the yychar entry, remove mention of the local yychar case (pure
6127 parser) since this is irrelevant information when writing semantic
6128 actions and since it's already discussed in `Table of Symbols' where
6129 yychar is otherwise described as an external variable.
6130 In the yychar entry, don't call it the `current' look-ahead since it
6131 isn't when semantic actions are deferred.
6132 In the yychar and yyclearin entries, add note about deferred semantic
6133 actions.
6134 Add yylloc and yylval entries discussing look-ahead usage.
6135 (Look-Ahead Tokens): When discussing yychar, don't call it the
6136 `current' look-ahead, and do mention yylval and yylloc.
6137 (Error Recovery): Cross-reference `Action Features' when mentioning
6138 yyclearin.
6139 (Table of Symbols): In the yychar entry, don't call it the `current'
6140 look-ahead.
6141 In the yylloc and yylval entries, mention look-ahead usage.
6142
6143 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6144
6145 * tests/glr-regression.at: Update copyright year to 2006.
6146
6147 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6148
6149 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
6150 use during nondeterministic operation to track which stacks have
6151 actually needed the current lookahead.
6152 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
6153 Allocate, deallocate, resize, and otherwise shuffle space for
6154 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
6155 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
6156 appropriately during nondeterministic operation.
6157 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
6158 members to store the current lookahead to be used by the deferred
6159 user action.
6160 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6161 from which the RHS is taken. Set the lookahead members of the new
6162 yySemanticOption according to the lookahead status for stack yyk.
6163 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
6164 yyaddDeferredAction.
6165 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
6166 members of yySemanticOption before invoking yyuserAction, and then set
6167 them back to their current values afterward.
6168 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
6169 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
6170 * tests/glr-regression.at: Remove `.' from the ends of recent test case
6171 titles for consistency.
6172 (Leaked merged semantic value if user action cuts parse): In order to
6173 suppress lint warnings, use arguments in merge function, and assign
6174 char value < 128 in main.
6175 (Incorrect lookahead during deterministic GLR): New test case.
6176 (Incorrect lookahead during nondeterministic GLR): New test case.
6177
6178 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6179
6180 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
6181 !yyvaluep as signal that no semantic value is available to print.
6182 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
6183 to print a semantic value.
6184
6185 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6186
6187 * tests/glr-regression.at: For consistency with my newer test cases,
6188 don't thank myself.
6189
6190 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6191
6192 * data/glr.c (yyresolveValue): When merging semantic options, if at
6193 least one user action succeeds but a later one cuts the parse, then
6194 destroy the semantic value before returning rather than leaking it.
6195 (yyresolveStates): If a user action cuts the parse and thus
6196 yyresolveValue fails, ignore the (unset) semantic value rather than
6197 corrupting the yyGLRState, and empty the semantic options list since
6198 the user actions should have called all necessary destructors.
6199 Simplify code with YYCHK.
6200 * tests/glr-regression.at (Corrupted semantic options if user action
6201 cuts parse): New test case.
6202 (Undesirable destructors if user action cuts parse): New test case.
6203 Before applying any of this patch, this test case never actually failed
6204 for me... but only because the corrupted semantic options usually
6205 masked this bug.
6206 (Leaked merged semantic value if user action cuts parse): New test
6207 case.
6208
6209 2006-01-05 Akim Demaille <akim@epita.fr>
6210

6219 b4_c_modern.
6220 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
6221 than rolling our own.
6222
6223 2006-01-04 Akim Demaille <akim@epita.fr>
6224
6225 Also warn about non-used mid-rule values.

6247 --yacc does.
6248 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
6249 about declarations in the grammar when in Yacc mode, as POSIX does
6250 not require a diagnostic when the grammar uses extensions.
6251
6252 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
6253
6254 Warn about dubious constructions like "%token T T".
6255 Reported by twlevo.

6265 Use muscle_code_grow, so that we don't need stype_line any more.
6266 All uses changed.
6267
6268 * src/muscle_tab.c (muscle_grow): Fix comment.
6269
6270 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:

6272 Update copyright year to 2006.
6273
6274 2006-01-03 Akim Demaille <akim@epita.fr>
6275
6276 Have glr.cc pass (some of) the calc.at tests.
6277 * data/glr.cc (b4_parse_param_orig): New.
6278 (b4_parse_param): Improve its definition, and bound it more
6279 clearly in the skeleton.
6280 (b4_epilogue): Append, instead of prepending, in order to keep
6281 #line consistency.
6282 Simplify the generation of auxiliary functions: locations and
6283 purity are mandated.
6284 (b4_global_tokens_and_yystype): Honor it.
6285 * data/location.cc (c++.m4): Don't include it.
6286 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
6287 and AT_SKEL_CC_IF.

6289 AT_LALR1_CC_IF.
6290 Be sure to initialize the first position's filename.
6291 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
6292 mandated anyway.
6293 (AT_CHECK_CALC_GLR_CC): New.
6294 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
6295
6296 2006-01-02 Akim Demaille <akim@epita.fr>
6297
6298 * src/output.c (output_skeleton): Don't hard wire the inclusion of
6299 c.m4.

6307 * tests/cxx-type.at: Reformat whitespace with tabs.
6308 (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo
6309 since it's a member. Rename type to isNterm for clarity.
6310
6311 2005-12-29 Akim <akim@sulaco.local>
6312
6313 Let glr.cc catch up with symbol_value_print.

6317
6318 2005-12-28 Paul Eggert <eggert@cs.ucla.edu>
6319
6320 * src/location.h (boundary): Note that a line or column equal
6321 to INT_MAX indicates an overflow.
6322 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
6323 (rule_length_overflow, increment_rule_length, add_column_width):
6324 New functions.
6325 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):

6344
6345 2005-12-27 Akim Demaille <akim@epita.fr>
6346
6347 * src/reader.c (grammar_current_rule_check): Also check that $$
6348 is used.
6349 Take the rule to check as argument, hence rename as...
6350 (grammar_rule_check): this.
6351 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
6352 Rename as...
6353 (grammar_rule_begin, grammar_rule_end): these, for consistency.
6354 (grammar_midrule_action, grammar_symbol_append): Now static.
6355 * tests/torture.at (input): Don't rely on the default action

6357 * tests/calc.at: "Set" $$ even when the action is "cut" with
6358 YYERROR or other.

6363
6364 * NEWS: Improve wording for unused-value warnings.

6369 (b4_yysymprint_generate): Rename as...
6370 (b4_yy_symbol_print_generate): this.

6373
6374 2005-12-22 Akim Demaille <akim@epita.fr>
6375
6376 * NEWS: Warn about unused values.
6377 * src/symlist.h, src/symlist.c (symbol_list, symbol_list_new): Add

6388 -pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
6389 * tests/actions.at (Exotic Dollars): Use unused values.
6390 * tests/calc.at: Likewise.
6391 * tests/glr-regression.at (No users destructors if stack 0 deleted):

6394 * src/gram.c (rule_useful_p, rule_never_reduced_p): Use
6395 rule_useful_p.
6396
6397 2005-12-21 Paul Eggert <eggert@cs.ucla.edu>
6398
6399 Undo 2005-12-01 tentative license wording change. The wording is
6400 still being reviewed by the lawyers, and we don't want to wait for
6401 them before publishing a test release. For now, revert to the
6402 previous wording.
6403 * NEWS: Undo 2005-12-01 change.
6404 * data/glr.c: Revert to previous license wording.
6405 * data/glr.cc: Likewise.
6406 * data/lalr1.cc: Likewise.
6407 * data/location.cc: Likewise.
6408 * data/yacc.c: Likewise.
6409
6410 * NEWS: Reword %destructor vs YYABORT etc.
6411 * data/glr.c: Use American spacing, for consistency.
6412 * data/glr.cc: Likewise.
6413 * data/lalr1.cc: Likewise.
6414 * data/yacc.c: Likewise.
6415 * data/yacc.c: Reformat comments slightly.

6420
6421 2005-12-21 Joel E. Denny <address@hidden>
6422
6423 * tests/cxx-type.at: Construct a tree, count the parents of shared
6424 nodes, and free each node once and only once. Previously, the memory
6425 for semantic values was leaked instead.
6426
6427 2005-12-21 Joel E. Denny <address@hidden>
6428
6429 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
6430 (yylval, yylloc): If pure, #define to yystackp->yyval and
6431 yystackp->yyloc similar to yychar and yynerrs.
6432 (yyparse): If pure, remove local yylval and yylloc. Add local
6433 yystackp to accommodate pure definitions of yylval and yylloc.
6434 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
6435 yylvalp and yyllocp to &yylval and &yylloc.
6436 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
6437 namespace. Previously, nerrs and char were missing, but lval and lloc
6438 weren't necessary.
6439 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
6440 yylvalp and yyllocp parameters since, if pure, these are now always
6441 accessible through yystackp. If not pure, they are still accessible
6442 globally.
6443 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
6444 `if (YYID (N))' to pacify lint.
6445
6446 2005-12-21 Akim Demaille <akim@epita.fr>
6447
6448 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
6449 destroy the RHS symbols of a rule.
6450 * data/yacc.c (yylen): Initialize to 0.
6451 Keep its value to the number of items to possibly shift.
6452 In particular, a regular successful parse that ends on YYFINAL by
6453 a (internal) YYACCEPT must not have yylen != 0.
6454 (yyerrorlab, yyreturn): Pop the RHS.
6455 Reorder a bit to emphasize the `shifting' bits of code.
6456 (YYPOPSTACK): Now accept a number of items to pop.
6457 * data/lalr1.cc: Likewise.
6458 * data/glr.c: Formatting changes.
6459 Use goto instead of fall through.
6460 * doc/bison.texinfo (Destructor Decl): Complete.

6466 * djgpp/config.bat: Replace every occurence of the file name
6467 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
6468 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
6469 * djgpp/config.sed: Replace every occurence of the file name
6470 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
6471 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
6472 * djgpp/djunpack.bat: DJGPP specific file.
6473 * djgpp/fnchange.lst: DJGPP specific file.
6474 * djgpp/README.in: Add new information about how to unpack the bison
6475 source on MSDOS and other systems which have 8.3 file name restrictions
6476 using djunpack.bat and fnchange.lst.
6477
6478 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
6479
6480 * bootstrap (build_cvs_prefix): Remove; unused.

6482 when getting gnulib.
6483
6484 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
6485
6486 * data/glr.c: Reorder typedef declarations for structs to match order
6487 of struct declarations.
6488 Rename yystack everywhere to yystackp except in yyparse where it's not
6489 a pointer.
6490 (yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
6491 consistency.
6492 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
6493 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
6494 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
6495 lint.
6496
6497 2005-12-09 Paul Eggert <eggert@cs.ucla.edu>
6498
6499 * tests/sets.at (Accept): Fix typos in regular expression used to
6500 sed out the final state number.
6501
6502 Work around portability problem on Solaris 10: flex-generated
6503 files include <stdio.h> before <config.h>, which messes up
6504 because the latter defines __EXTENSIONS__. Address the problem
6505 by creating two new little files that include <config.h> first,
6506 then include the flex-generated files. Rewrite everyone else
6507 to include <config.h> first, as well.
6508 * lib/timevar.c: Always include "config.h".
6509 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

6543 (current_lhs, current_lhs_location): Now static.
6544 (current_assoc): Remove unused variable.
6545
6546 Cleanups so that Bison-generated parsers have less lint.
6547 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
6548 Prepend /*ARGSUSED*/, for lint's sake.
6549 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
6550 definition if 'lint' is defined.
6551 (YYID): New macro (or function, if lint).
6552 All uses of /*CONSTCOND*/0 replaced by YYID(0).
6553 * data/yacc.c: Likewise.
6554 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
6555 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
6556 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
6557 is C++ only.
6558 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
6559 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
6560 Use YYID(0) rather than 0, for lint.
6561 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
6562 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
6563
6564 2005-12-07 Paul Eggert <eggert@cs.ucla.edu>

6573 all stacks.
6574 (yyparse): Iterate another stack in order to call user destructors.
6575 * tests/glr-regression.at (No users destructors if stack 0 deleted):
6576 New test case.
6577 (Duplicated user destructor for lookahead): This test now is expected
6578 to succeed.
6579
6580 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
6581
6582 * NEWS: Document the following change.
6583 * data/yacc.c: Say "parser skeleton" rather than "file", since
6584 it's no longer just a file.
6585 * data/glr.c: Grant a special exception for C GLR parsers, that
6586 reads like the already-existing exception for C LALR(1) parsers.
6587 * data/glr.cc: Likewise.
6588 * data/lalr1.cc: Likewise.
6589 * data/location.cc: Likewise.
6590 * data/yacc.c: Reword the "written by" statement to clarify that
6591 it was the parser skeleton, not the entire output file.
6592 * data/glr.c: Written by Paul Hilfinger.
6593 * data/glr.cc: Written by Akim Demaille.
6594 * data/lalr1.cc: Likewise.

6597
6598 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
6599 Fix typos in previous change that broke 'make check'.
6600 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
6601 supported in C.
6602 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
6603 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
6604 We can revert this once things settle down.
6605
6606 * src/conflicts.c (conflicts_print): Don't print file name twice
6607 when %expect fails because there were no conflicts.
6608 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
6609 change.
6610 * tests/conflicts.at (%expect not enough, %expect too much):
6611 (%expect with reduce conflicts): Adjust to new behavior.
6612
6613 2005-11-18 Akim Demaille <akim@epita.fr>
6614

6618 * doc/bison.texinfo (Expect Decl): Likewise.
6619
6620 2005-11-16 Akim Demaille <akim@epita.fr>

6635 2005-11-14 Akim Demaille <akim@epita.fr>
6636
6637 * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
6638 from 1 to N, while values and location start at 0.
6639 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
6640

6741
6742 2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
6743
6744 * bootstrap (cleanup_gnulib): New function. Use it to clean up
6745 gnulib when interrupted. This fixes some race conditions and
6746 works around some portability problems (one noted by Paul
6747 Hilfinger).
6748
6749 2005-10-22 Akim <akim@epita.fr>
6750
6751 * Makefile.cfg: Adjust to config -> build-aux.

6774
6775 * examples/calc++/test: Use set -x only when VERBOSE.
6776
6777 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
6778
6779 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
6780 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
6781
6782 2005-10-13 Akim Demaille <akim@epita.fr>
6783
6784 * src/scan-skel.l: Output the base name parts of the parser and
6785 header file names.
6786 * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
6787 additional checks.

6790
6791 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
6792
6793 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
6794 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
6795 Problem reported by John P. Hartmann.
6796 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
6797 already defined it.
6798
6799 2005-10-12 Akim Demaille <akim@epita.fr>
6800

6847 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
6848
6849 Undo the parts of the unlocked-I/O change that substituted
6850 putc or puts for printf. This might hurt performance a bit,
6851 but some people prefer the printf style.
6852 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
6853 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

6874 unused-variable warnings.
6875
6876 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

6879
6880 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
6881
6882 Use unlocked I/O for a minor performance improvement on hosts like
6883 GNU/Linux and Solaris that support unlocked I/O. The basic idea
6884 is to use the gnlib unlocked-io module, and to prefer putc and
6885 puts to printf when either will work (since the latter doesn't
6886 come in an unlocked flavor).
6887 * bootstrap (gnulib_modules): Add unlocked-io.
6888 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
6889 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

6891 and similarly for puts and putc and printf.
6892 * data/yacc.c: Likewise.
6893 * lib/bitset.c (bitset_print): Likewise.
6894 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.

6905 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
6906 * src/system.h: Include unlocked-io.h rather than stdio.h.
6907
6908 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
6909 this confuses xgettext.

6955 for posix systems.
6956
6957 * lib/subpipe.h: New function end_of_output_subpipe() added
6958 to allow support for non-posix systems. This is a no-op function
6959 for posix systems.
6960
6961 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
6962 handle the lack of pipe/fork functionality on non-posix systems.

6985 filename type is defined by the user.
6986 Forward declation location and position before the pre-prologue.

7029 local variables.
7030 (yysyntax_error_): Takes the state number as argument.
7031 (yyreduce_print_): Use the argument yyrule, not the former

7055 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
7056 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
7057 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
7058 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
7059 to match yacc.c, to test more hosts.
7060
7061 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
7062
7063 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
7064 doesn't affect behavior.
7065 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
7066 Solaris, AIX, MSC.
7067 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
7068 This works a bit better with glibc, if user code has already included
7069 stdlib.h.
7070 * doc/bison.texinfo (Bison Parser): Document that users can't
7071 arbitrarily use malloc and free for other purposes. Document
7072 that <alloca.h> and <malloc.h> might be included.
7073 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
7074 user must declare alloca.
7075
7076 * HACKING (release): Forwarn the Translation Project about
7077 stable releses.

7084
7085 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
7086 (YYSTACK_ALLOC_MAXIMUM): Use it.
7087 (yysyntax_error): New function.
7088 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7089 multiple syntax errors are reported, and alloca is being used.
7090 Instead, reallocate buffers twice as big each time, so that
7091 we waste at most half the allocated memory. Start with a small
7092 (128-byte) buffer that will suffice in most cases anyway.
7093 Use yysyntax_error to do most of the work.
7094
7095 * doc/bison.texinfo (Error Reporting, Table of Symbols):
7096 yynerrs is the number of errors reported, not the number of
7097 errors encountered.
7098
7099 * tests/glr-regression.at (Duplicated user destructor for lookahead):
7100 Mark it as expected to fail.
7101 Cast result of malloc; problem reported by twlevo@xs4all.nl.
7102 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
7103 Don't start user-code symbols with "yy", to avoid name space problems.
7104
7105 2005-09-19 Akim Demaille <akim@epita.fr>
7106
7107 Remove the traits, failed experiment.
7108 It never proved useful, and anyway because of the current
7109 definition, it was not possible to have several specialization of
7110 this traits, making it useless.
7111 * data/lalr1.cc (yy:traits): Remove.
7112 Inline its definitions in the parser class.
7113
7114 2005-09-19 Akim Demaille <akim@epita.fr>
7115
7116 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at
7117 least Mac OSX with a /usr/local install of gettext.
7118
7119 2005-09-19 Akim Demaille <akim@epita.fr>
7120
7121 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
7122 and yytoken for similarity with the other skeletons.
7123

7135 diagnostic.
7136 * src/output.c (prepare): Likewise.
7137 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
7138 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
7139 is not defined. This is an awful hack, but it's enough for now.
7140 All callers changed.
7141 * tests/glr-regression-at (make_value): Args are const pointers now,
7142 to avoid GCC warning.
7143 (Duplicated user destructor for lookahead): New test. Currently
7144 skipped. It fails on my host but I'm not sure it'll always fail.
7145
7146 2005-09-16 Akim Demaille <akim@epita.fr>
7147
7148 * src/symtab.h (struct symbol): Declare the printer and destructor
7149 as const, to avoid accidental calls to free.
7150 (symbol_destructor_set, symbol_printer_set): Adjust.
7151 * src/symtab.c: Adjust.
7152
7153 2005-09-16 Akim Demaille <akim@epita.fr>
7154
7155 * data/c.m4 (b4_token_enums): New.
7156 (b4_token_defines): Rename as...
7157 (b4_token_enums_defines): this.
7158 (b4_token_defines): New, output only the #defines.
7159 * data/yacc.c, data/glr.c: Adjust.
7160 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
7161 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
7162 as default values.
7163
7164 2005-09-16 Akim Demaille <akim@epita.fr>
7165
7166 * data/lalr1.cc (yylex_): Remove, inline its code.
7167 (yyreport_syntax_error_): Remove, replaced by...
7168 (yysyntax_error_): this which returns a string and leaves to the
7169 caller the call to the users' error function.
7170 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
7171 Move from members of the parser object...
7172 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
7173 to local variables of the parse function.
7174
7175 2005-09-16 Akim Demaille <akim@epita.fr>
7176
7177 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
7178 since it's in Bison's name space.
7179
7180 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
7181
7182 * data/glr.c (yyresolveValue): Add default case to pacify
7183 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
7184
7185 * NEWS: Document when yyparse started to return 2.
7186 * doc/bison.texinfo (Parser Function): Document when yyparse
7187 returns 2.
7188
7189 * data/lalr1.cc: Revert part of previous change, as it's incompatible.

7191 changed.
7192 (class position): file_name -> filename (reverting). All uses changed.
7193
7194 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
7195
7196 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
7197 do anything if $@ exists. This reverts part of the 2005-07-07
7198 patch.
7199
7200 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
7201
7202 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
7203 contains obsolete information and isn't worth distributing as a
7204 separate file anyway.
7205 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
7206 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
7207 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
7208 (yyparse): Abort if user code uses longjmp to throw an unexpected
7209 value.
7210
7211 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
7212
7213 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
7214 Suggested by twlevo@xs4all.nl.
7215
7216 * data/glr.c (YYCHK1): Do not assume YYE is in range.
7217 This avoids a diagnostic from gcc -Wswitch-enum.
7218 Problem reported by twlevo@xs4all.nl.
7219
7220 * doc/bison.texinfo: Don't use "filename", as per GNU coding
7221 standards. Use "file name" or "file" or "name", depending on
7222 the context.
7223 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
7224 not to hack/foo.tab.c.
7225 (Calc++ Top Level): 2nd arg of main is not const.
7226 * data/glr.c: b4_filename -> b4_file_name.
7227 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
7228 All uses changed.
7229 (class position): filename -> file_name. All uses changed.
7230 * data/yacc.c: b4_filename -> b4_file_name.
7231 * lib/bitset.h: filename -> file_name in local vars.
7232 * lib/bitset_stats.c: Likewise.
7233 * src/files.c: Likewise.
7234 * src/scan-skel.l ("@output ".*\n): Likewise.
7235 * src/files.c (file_name_split): Renamed from filename_split.
7236 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
7237
7238 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
7239
7240 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
7241 to accommodate latest gnulib.
7242
7243 * tests/glr-regression.at (Duplicate representation of merged trees):
7244 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
7245
7246 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
7247 needed.
7248
7249 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7250
7251 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
7252 All uses changed. Invoke user destructor after an error during a
7253 split parse (trivial change from Joel E. Denny).
7254
7255 * tests/glr-regression.at
7256 (User destructor after an error during a split parse): New test case.
7257 Problem reported by Joel E. Denny in:
7258 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
7259
7260 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7261
7262 * README-cvs: Give URLs for recommended tools.
7263 Mention Gzip version problem, and bootstrapping issues.
7264 Remove troubleshooting section, as it's somewhat obsolete.
7265
7266 * bootstrap (no_cache): New var, to accommodate different wget
7267 variants. Use it instead of '-C off'. Problem reported by
7268 twlevo@xs4all.nl.
7269
7270 * data/glr.c (yydestroyStackItem): New function.
7271 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
7272 debugging information. Problem reported by Joel E. Denny.
7273
7274 2005-08-25 Akim Demaille <akim@epita.fr>
7275
7276 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
7277
7278 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
7279

7285 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
7286
7287 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>

7291 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
7292 lib-prefix.m4, po.m4.
7293
7294 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
7295 in yydestruct diagnostic, since it might not be an error.
7296 Problem reported by Joel Denny near end of
7297 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7298 * data/lalr1.cc (yyerturn): Likewise.
7299 * data/yacc.c (yyreturn): Likewise.
7300 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
7301
7302 * src/files.c: Remove obsolete FIXME comment.
7303
7304 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
7305 with the other templates, and to fix bogus run-on messages such
7306 as the one reported at the end of
7307 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7308 All callers changed to avoid the newline.
7309 (yyprocessOneStack): Output two lines rather than one, to accommodate
7310 the above change. This changes the debug output format slightly.
7311
7312 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
7313 reported by Joel E. Denny in
7314 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
7315 (trivial change).
7316 * tests/glr-regression.at (Duplicate representation of merged trees):
7317 New test, from Joel E. Denny in:
7318 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
7319 * THANKS: Add Joel E. Denny.
7320
7321 * configure.ac (AC_INIT): Bump to 2.0c.
7322
7323 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
7324
7325 * NEWS: Version 2.0b.
7326
7327 * Makefile.am (SUBDIRS): Put examples before tests, so that
7328 "make check" doesn't finish with "All 1 tests passed".
7329
7330 * tests/regression.at (Token definitions): Don't rely on
7331 AT_PARSER_CHECK for data that contains backslashes. It currently
7332 uses 'echo', and 'echo' isn't portable if its argument contains
7333 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7334 that the byte '\0xff' is not printable in the C locale; it is,
7335 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7336 not printable, so use '\0x81' to test.
7337
7338 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
7339 version of GCC, since the macro is used with non-GCC compilers.
7340
7341 Fix core dump reported by Pablo De Napoli in
7342 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
7343 * tests/regression.at (Invalid inputs with {}): New test.
7344 * src/parse-gram.y (token_name): Translate type before using
7345 it as an index.
7346
7347 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
7348 the user's name space. All uses changed to __attribute__
7349 ((__unused__)).
7350 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
7351 Add __attribute__ ((__noreturn__)).
7352
7353 * etc/clcommit: Remove. We weren't using it, and it failed
7354 "make maintainer-distcheck".
7355 * Makefile.maint: Merge from coreutils.
7356 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
7357 (syntax-check-rules): Change list of rules as described below.
7358 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
7359 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):

7363 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
7364 (sc_space_tab, sc_error_exit_success, sc_changelog):
7365 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
7366 (makefile-check, po-check, author_mark_check):
7367 (makefile_path_separator_check, copyright-check):
7368 Use grep -n, to make it easier to find violations.
7369 Use CVS_LIST and CVS_LIST_EXCEPT.
7370 (header_regexp, h_re): Remove.
7371 (dd_c): New macro.
7372 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
7373 (my-distcheck): Use more-modern GCC flags.
7374 (signatures, %.asc): Remove.
7375 (rel-files, announcement): Remove signatures.
7376 Restore old updating code, even though we don't use it, so
7377 that we're the same as coreutils.
7378 (alpha, beta, major): Depend on news-date-check.
7379 Make the upload commands.
7380
7381 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

7388 * tests/sets.at: Likewise.
7389
7390 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
7391 we comment out the Autoconf version number.
7392 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
7393 it's error-prone and "make maintainer-distcheck" rejects it.
7394
7395 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
7396 Indent calls to "error" to pacify "make maintainer-distcheck",
7397 when the calls are not intended to be translated.
7398 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
7399
7400 * src/Makefile.am (DEFS): Use +=, to pacify
7401 "make maintainer-distcheck".
7402 (bison_SOURCES): Add scan-skel.h.
7403 (sc_tight_scope): New rule, from coreutils.
7404
7405 * src/files.c (src_extension, header_extension):
7406 Now static, not extern.
7407 * src/getargs.c (short_options): Likewise.
7408 * src/muscle_tab.c (muscle_table): Likewise.
7409 * src/parse-gram.y (current_class, current_type, current_prec):
7410 Likewise.
7411 * src/reader.c (grammar_end, previous_rule_end): Likewise.
7412 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
7413 * src/main.c (main): Cast bindtextdomain and textdomain calls to
7414 void, to avoid warning when NLS is disabled.
7415 * src/output.c: Include scan-skel.h.
7416 (scan_skel): Remove decl, since scan-skel.h does this.
7417 (output_skeleton):
7418 Indent calls to "error" to pacify "make maintainer-distcheck".
7419 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
7420 * src/reader.h (gram_end, gram_lineno): New decls to pacify
7421 "make maintainer-distcheck".
7422 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
7423 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
7424 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
7425 (skel_lex_destroy, scan_skel): Move these decls to...
7426 * src/scan-skel.h: New file.
7427 * src/uniqstr.c (uniqstr_assert):
7428 Indent calls to "error" to pacify "make maintainer-distcheck".
7429
7430 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
7431 not @VAR@.
7432
7433 * tests/torture.at: Revamp to avoid misuse of atoi that
7434 "make maintainer-distcheck" complained about.
7435
7436 * examples/extexi (message): Don't print a message more than once,
7437 and omit line-number decoration that makes Emacs compile think
7438 that informative messages are worth worrying about.
7439
7440 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
7441
7442 * configure.ac: Update version number.
7443
7444 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
7445 accidentally.
7446 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
7447 autogenerated by the maintainer.
7448 * examples/calc++/.cvsignore: Add *.yy.
7449
7450 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
7451 * lib/bitset_stats.c (bitset_stats_init): Likewise.
7452 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7453
7454 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
7455
7456 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
7457 from maintainer-distcheck about casting the argument of 'free'.
7458
7459 * NEWS: Mention recent yytname changes.
7460 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
7461
7462 * bootstrap: For translations that have not yet been upgraded to
7463 the new runtime-po domain, prime the pump by extracting the
7464 relevant strings from the obsolete translations. This code can be
7465 removed once the bison-runtime domain has been translated by each
7466 team.
7467
7468 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
7469 now that token names are already quoted.
7470
7471 Fix problem reported by Anthony Heading.
7472 * data/glr.c (YYTOKEN_TABLE): New macro.
7473 (yytname): Define if YYTOKEN_TABLE.
7474 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
7475 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
7476 (YYERROR_VERBOSE): Define the same way the other skeletons do.
7477 * src/output.c (prepare_symbols): Output token_table_flag.
7478
7479 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
7480
7481 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
7482 again if the first call fails.
7483
7484 * data/glr.c (yytnamerr): New function.
7485 (yyreportSyntaxError): Use it to dequote most string literals.
7486 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
7487 with other skeletons. All uses changed.
7488 (yytnameerr_): New function.
7489 (yyreport_syntax_error): Use it to dequote most string literals.
7490 * data/yacc.c (yytnamerr): New function.
7491 (yyerrlab): Use it to decode most string literals.
7492 * doc/bison.texinfo (Decl Summary, Calling Convention):
7493 Clarify quoting convention of yytname.
7494 * src/output.c (prepare_symbols): Quote all names. This undoes
7495 the 2005-04-17 change, which is now accomplished (mostly) via
7496 changes in the parsers as described above.
7497 * tests/regression.at (Token definitions, Web2c Actions):
7498 Undo most 2005-04-17 change here, too.
7499
7500 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
7501
7502 Fix more problems reported by twlevo@xs4all.nl.
7503 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7504 remove trailing spaces. This loses the exit status of ./types,
7505 and isn't needed since ./types shouldn't be emitting trailing
7506 spaces.
7507 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7508 as the stack isn't valid in that case.
7509
7510 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7511 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7512 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7513 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
7514 is used.
7515 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
7516 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
7517 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
7518 Likewise.
7519
7520 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
7521 overly-picky compilers that reject 'char *foo = "bar";'.
7522
7523 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7524 to FILE * parameter, not to stderr. This fixes a typo introduced
7525 in the 2005-07-12 change.
7526
7527 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
7528 warnings from GCC 4.
7529
7530 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
7531 (yyglrShiftDefer, yysplitStack):
7532 Remove unused parameters b4_pure_formals. All uses changed.
7533 (yyglrShift): Remove unused parameters b4_user_formals.
7534 All uses changed.
7535 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
7536
7537 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
7538
7539 Destructor cleanups and regularization among the three skeletons.
7540 * NEWS: Document the behavior changes.
7541 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
7542 stack before failing, as the cleanup code will do it for us now.
7543 * data/lalr1.cc (yyerrlab): Likewise.
7544 * data/glr.c (yyparse): Pop everything off the stack before
7545 freeing it, so that destructors get called properly.
7546 * data/lalr1.cc (yyreturn): Likewise.
7547 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
7548 This is more consistent.
7549 * doc/bison.texinfo (Destructor Decl): Mention more reasons
7550 why destructors might be called. 1.875 -> 2.1.
7551 (Destructor Decl, Decl Summary, Table of Symbols):
7552 Some English-language cleanups for %destructor.
7553 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
7554 Add output line for destructor of start symbol.
7555 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
7556 because of that same extra output line.
7557
7558 * NEWS: Document minor wording changes in diagnostics of
7559 Bison-generated parsers.
7560 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
7561 Remove unused formals. All uses changed.
7562 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
7563 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
7564 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
7565 Rename yyoverflowab to yyexhaustedlab.
7566 When memory exhaustion occurs during syntax-error reporting,
7567 report it separately rather than in a single diagnostic; this
7568 eases translation.
7569 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
7570 (Memory Exhausted): Renamed from Parser Stack Overflow.
7571 Revamp wording slightly to prefer "memory exhaustion".
7572 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
7573
7574 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
7575
7576 Add i18n support to the GLR skeleton. Partially fix the C++
7577 skeleton; a C++ expert needs to finish this. Remove debugging
7578 msgids; there's little point to having them translated, since they
7579 can be understood only by someone who can read the
7580 (English-language) source code.
7581
7582 Generate runtime-po/bison-runtime.pot automatically, so that we
7583 don't have to worry about garbage getting in that file. We'll
7584 make sure after the next official release that old msgids don't
7585 get lost. See
7586 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
7587
7588 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
7589 Now auto-generated.
7590 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7591 Fix typos in explanations of the runtime file.
7592 * bootstrap: Change gettext keyword from YYI18N to YY_.
7593 Use standard Makefile.in.in in runtime-po, since we'll arrange
7594 for backward-compatible bison-runtime.po files in a different way.
7595 * data/glr.c (YY_): New macro, from yacc.c.
7596 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7597 Translate messages intended for users.
7598 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7599 the wording in the other skeletons. We don't know that the memory
7600 is virtual.
7601 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7602 Use same method that yacc.c uses.
7603 Don't translate debugging messages.
7604 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7605 it doesn't work (yet), and requires C++ expertise to fix.
7606 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7607 Move defn to a more logical place, to be consistent with other
7608 skeletons.
7609 Don't translate debugging messages.
7610 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7611 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7612 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7613 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
7614
7615 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
7616 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
7617 void, not int.
7618 * tests/glr-regression.at (Badly Collapsed GLR States):
7619 Likewise.
7620 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7621 yylex should return 0 at EOF rather than aborting.
7622
7623 Improve tests for stack overflow in GLR parser.
7624 Problem reported by twlevo@xs4all.nl.
7625 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
7626 All uses removed.
7627 (yyStackOverflow): Just longjmp, but with value 2 so that caller
7628 can handle the problem.
7629 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
7630 (yyparse): New local variable yyresult to record the result.
7631 Use result of setjmp to set it, rather than storing itinto
7632 struct.
7633 (yyDone): Remove label.
7634 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
7635 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7636 if YYABORT is used).
7637 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
7638 yyparse status; put status > 1 into diagnostic.
7639 Check that status==2 works.
7640 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
7641 Use exit status 3 for failure to open (which shouldn't happen).
7642
7643 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
7644
7645 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
7646 1 on syntax error; just let yyparse do its thing.
7647 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
7648 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
7649 (Exploding the Stack Size with Alloca):
7650 (Exploding the Stack Size with Malloc):
7651 Expect exit status 2, not 1, since the parser is supposed to blow
7652 its stack. Problem reported by twlevo@xs4all.nl.
7653
7654 * data/glr.c (yyparse): Don't assume that the initial calls
7655 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
7656 Print a stack-overflow message and fail instead.
7657 Initialize the line-number information before creating the stack,
7658 so that the stack-overflow message can report line zero safely.
7659
7660 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
7661
7662 Fix problems reported by twlevo@xs4all.nl.
7663 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
7664 (yyuserMerge): Provide a default case if b4_mergers is empty.
7665 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
7666 * tests/glr-regression.at
7667 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7668 Add casts to pacify C++ compilers.
7669 * tests/glr-regression.at (Improper merging of GLR delayed action
7670 sets): Declare yylex before using it.
7671 * tests/Makefile.am (maintainer-check-g++): Fix a stray
7672 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
7673 test for valgrind; valgrind is independent of g++.
7674 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
7675 for compatibility with POSIX 1003.1-2001 (if running coreutils).
7676 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
7677 Use a destructor, so that we can expand the stack. Change
7678 YYSTYPE to char * so that we can free it. Cast result of malloc.
7679
7680 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7681
7682 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
7683 a valgrind failure. Problem reported by twlevo@xs4all.nl.
7684
7685 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
7686
7687 * PACKAGING: New file, suggested by Bruno Haible and taken from
7688 similar wording in gettext's PACKAGING file.
7689 * NEWS: Mention PACKAGING.
7690 * Makefile.am (EXTRA_DIST): Add PACKAGING.
7691
7692 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
7693
7694 * NEWS: Document recent i18n improvements.
7695 * bootstrap: Get runtime translations into runtime-po.
7696 Create runtime-po files automatically, if possible.
7697 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
7698 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
7699 does not infringe on the user's name space.
7700 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
7701 * doc/bison.texinfo (Internationalization): Revamp the English
7702 and Texinfo syntax a bit, to try to make it clearer.
7703 (Bison Options, Option Cross Key): Mention --print-localedir.
7704 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
7705 YYENABLE_NLS. Quote a bit more.
7706 * runtime-po/.cvsignore: New file.
7707 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
7708 * runtime-po/Rules-quot: Remove; now created by bootstrap.
7709 * runtime-po/quot.sed: Likewise.
7710 * runtime-po/boldquot.sed: Likewise.
7711 * runtime-po/en@quot.header: Likewise.
7712 * runtime-po/en@boldquot.header: Likewise.
7713 * runtime-po/insert-header.sin: Likewise.
7714 * runtime-po/remove-potcdate.sin: Likewise.
7715 * runtime-po/Makevars: Likewise.
7716 * runtime-po/LINGUAS: Likewise.
7717 * runtime-po/de.po: Likewise; we will rely on the translation project
7718 to maintain this, so "bootstrap" should get it.
7719 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
7720 its value.
7721 * src/main.c (main): Bind the bison-runtime domain, too.
7722
7723 2005-07-12 Bruno Haible <bruno@clisp.org>
7724
7725 * data/yacc.c: Include <libintl.h> when NLS is enabled.
7726 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
7727 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
7728 * runtime-po: New directory.
7729 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
7730 $(DOMAIN).pot-update rule, so that old messages are never dropped.
7731 * runtime-po/Rules-quot: New file, copied from po/.
7732 * runtime-po/quot.sed: Likewise.
7733 * runtime-po/boldquot.sed: Likewise.
7734 * runtime-po/en@quot.header: Likewise.
7735 * runtime-po/en@boldquot.header: Likewise.
7736 * runtime-po/insert-header.sin: Likewise.
7737 * runtime-po/remove-potcdate.sin: Likewise.
7738 * runtime-po/Makevars: New file.
7739 * runtime-po/POTFILES.in: New file.
7740 * runtime-po/LINGUAS: New file.
7741 * runtime-po/bison-runtime.pot: New file.
7742 * runtime-po/de.po: New file.
7743 * m4/bison.m4: New file.
7744 * Makefile.am (SUBDIRS): Add runtime-po.
7745 (aclocaldir, aclocal_DATA): New variables.
7746 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
7747 Define aclocaldir.
7748 * src/getargs.c (usage): Document --print-localedir option.
7749 (PRINT_LOCALEDIR_OPTION): New enum item.
7750 (long_options): Add --print-localedir option.
7751 (getargs): Handle --print-localedir option.
7752 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
7753 (Internationalization): New section.
7754
7755 2005-07-12 Akim Demaille <akim@epita.fr>
7756
7757 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
7758 for consistency with the rest of the code.
7759 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
7760 Add separators.
7761
7762 2005-07-12 Akim Demaille <akim@epita.fr>
7763
7764 * src/parse-gram.y: Use %printer instead of YYPRINT.
7765
7766 2005-07-12 Akim Demaille <akim@epita.fr>
7767
7768 * src/symtab.h, src/symtab.c (symbol_print): New.
7769 * src/symlist.h, src/symlist.c (symbol_list_print): New.
7770 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
7771
7772 2005-07-12 Akim Demaille <akim@epita.fr>
7773
7774 * data/glr.c (b4_syncline): Fix (swap) the definitions of
7775 b4_at_dollar and b4_dollar_dollar.
7776
7777 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
7778
7779 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
7780 and Pennello's paper.
7781
7782 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
7783
7784 * data/yacc.c (yyparse): Undo previous patch. Instead,
7785 set yylsp[0] and yyvsp[0] only if the initial action
7786 sets yylloc and yylval, respectively.
7787
7788 * data/yacc.c (yyparse): In the initial action, set
7789 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
7790 This avoids the use of undefined variables if the initial
7791 action does not set yylloc and/or yylval.
7792
7793 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7794
7795 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
7796 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
7797 Remove from CVS. These files are automatically generated.
7798 * examples/extexi: Clarify that this file is now part of Bison,
7799 not GNU M4, and that it works with any POSIX-compatible Awk.
7800 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
7801 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
7802 so that we also get calc++-parser.yy. Geneate it.
7803 Use $(AWK), not gawk, since any conforming Awk will do.
7804 Put comment before action, since older 'make' can't handle comment
7805 in action.
7806 $(BUILT_SOURCES): List all built sources, not just some of them.
7807 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
7808 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
7809 $($(calc_sources_generated)): Remove unnecessary test for existence
7810 of target. (This had a shell syntax error anyway; a stray "x".)
7811 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
7812 calc++-parser.yy.
7813 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
7814
7815 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
7816 implied by the other modules.
7817
7818 2005-07-06 Akim Demaille <akim@epita.fr>
7819
7820 Bind examples/calc++ to the package.
7821 * examples/calc++/Makefile: Remove, replaced by...
7822 * examples/calc++/Makefile.am: ... this new file.
7823 * examples/calc++/test: Remove input.
7824 * examples/calc++/compile: Remove.
7825 * examples/Makefile.am: New.
7826 * configure.ac, Makefile.am: Adjust.
7827 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
7828
7829 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
7830
7831 * data/glr.c (yyFail): Drastically simplify; since the format argument
7832 never had any % directives, we can simply pass it to yyerror.
7833 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
7834 be modified later, as that is the usual style in glr.c.
7835 Problems reported by Paul Hilfinger.
7836
7837 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
7838 and size overflow errors.
7839 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
7840 in case the user prolog sets feature-test macros like _GNU_SOURCE.
7841 (YYSIZEMAX): New macro.
7842 (yystpcpy): New function, taken from yacc.c.
7843 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
7844 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
7845 so that we don't have to maintain their signatures.
7846 (yyFail): Check for buffer overflow, by using vsnprintf rather
7847 than vsprintf. Allocate a bigger buffer if possible.
7848 Report an error if buffer allocation fails.
7849 (yyStackOverflow): New function.
7850 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
7851 the initialization was successful. It might fail if storage was
7852 exhausted.
7853 (yyexpandGLRStack): Add more checks for storage allocation failure.
7854 Use yyStackOverflow to report failures.
7855 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
7856 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
7857 Don't assume stack number fits in int.
7858 (yysplitStack): Check for storage allocation failure.
7859 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
7860 can print diagnostics on storage allocation failure. All callers
7861 changed.
7862 (yyresolveValue): Use yybool for boolean.
7863 (yyreportSyntaxError): Check for size-calculation overflow.
7864 This code is taken from yacc.c.
7865 (yyparse): Check for storage allocation errors when allocating
7866 the initial stack.
7867
7868 2005-07-05 Akim Demaille <akim@epita.fr>
7869
7870 Extract calc++ from the documentation.
7871 * doc/bison.texinfo (Calc++): Add the extraction marks.
7872 * examples/extexi: New, from the aborted GNU Programming 2E.
7873 Separate the different paragraph of a file with empty lines.

7878 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
7879 class typedefs.
7880
7881 2005-06-22 Akim Demaille <akim@epita.fr>

7899 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
7900
7901 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
7902 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
7903 which stems from the 2005-05-27 patch.
7904
7905 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7906
7907 * data/glr.c: Modify treatment of unused parameters to permit use
7908 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
7909
7910 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
7911
7912 Fix infringement on user name space reported by Janos Zoltan Szabo.

7920 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7921
7922 Fix infringement on user name space reported by Bruno Haible.
7923 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
7924 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
7925 the user's name space.
7926 (alloca): Include <stdlib.h> to get it, if it's not built in.
7927 (YYMALLOC, YYFREE): Define only if needed.
7928 (malloc, free): Declare, but only if needed, as this infringes on
7929 the user name space.
7930
7931 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7932
7933 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.

7935 with %d format.
7936 * lib/ebitset.c (min, max): Undef before defining.
7937 * lib/vbitset.c (min, max): Likewise.
7938 * lib/subpipe.c (create_subpipe): Save local variables in case
7939 vfork clobbers them.
7940
7941 2005-05-24 Bruno Haible <bruno@clisp.org>
7942
7943 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
7944 error message syntax used by gcc-4.0.
7945
7946 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
7947
7948 * README: Mention m4 1.4.3. Remove obsolete advice about
7949 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
7950
7951 * bootstrap: Remove workaround for problem I encountered with
7952 gettext 0.14.1; it seems to be fixed now.
7953
7954 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
7955
7956 * NEWS: Version 2.0a.
7957
7958 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
7959 the previous change.
7960
7961 Various maintainer cleanups.
7962 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
7963 conftest*, for benefit of CVS commands run at the same time as
7964 "configure". Add build-aux, since "bootstrap" now creates it and
7965 its subfiles.
7966 * Makefile.cfg (move_if_change): Remove.
7967 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
7968 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
7969 (po_repo, do-po-update, po-update, wget_files, get-targets):
7970 (config.guess-url_prefix, config.sub-url_prefix):
7971 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
7972 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
7973 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
7974 Remove.
7975 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
7976 this is now the recommended name.
7977 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
7978 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
7979 ylwrap. These files now go into build-aux.
7980 * config/move-if-change: Remove.
7981 * config/prev-version.txt: Bump from 1.75 to 2.0.
7982
7983 * bootstrap: Add stdio-safer, unistd-safer modules.
7984 Remove m4/glibc2.m4 (introduced by latest gnulib, but
7985 we don't need it).
7986 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
7987 fopen-safer.c, stdio-safer.h, unistd-safer.h.
7988 * lib/subpipe.c: Include "unistd-safer.h".
7989 (create_subpipe): Make sure all the newly-created
7990 file descriptors are > 2, so that diagnostics don't
7991 get sent down them (which might cause Bison to hang, in theory).
7992 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
7993 * src/files.c (xfopen): Use fopen_safer, not fopen.
7994
7995 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
7996 yesterday's yacc.c fix.
7997
7998 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
7999
8000 * data/glr.c, data/lalr1.cc: Update copyright date.
8001
8002 Fix a destructor bug reported by Wolfgang Spraul in
8003 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
8004 * data/yacc.c (yyabortlab): Don't call destructor, and
8005 don't set yychar to EMPTY.
8006 (yyoverflowlab): Don't call destructor.
8007 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
8008 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
8009 since we no longer output the message "discarding lookahead token
8010 end of input ()".
8011
8012 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8013
8014 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8015 fix a small glitch in debugging output.
8016 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8017 after YY_SYMBOL_PRINT where needed.
8018
8019 (struct yyGLRState): Add some comments.
8020 (struct yySemanticOption): Add some comments.
8021 (union yyGLRStackItem): Add comment.
8022
8023 (yymergeOptionSets): Correct this to properly perform the union,
8024 avoiding infinite reported by Michael Rosien.
8025 Update comment.
8026
8027 * tests/glr-regression.at: Add test for GLR merging error reported
8028 by M. Rosien.
8029

8068 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8069
8070 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8071 Problem reported by Ralf Menzel.
8072
8073 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8074
8075 * tests/actions.at: Test that stack overflow invokes destructors.
8076 From Marcus Holland-Moritz.
8077 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8078 from here....
8079 (yyreturn): to here. That way, destructors are called properly
8080 even if the stack overflows, or the user calls YYACCEPT or
8081 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8082 (yyoverflowlab): Destroy the lookahead.
8083
8084 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8085
8086 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8087
8088 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8089
8090 * NEWS: Bison-generated C parsers no longer quote literal strings
8091 associated with tokens.
8092 * src/output.c (prepare_symbols): Don't escape strings,
8093 since users don't want to see C escapes.
8094 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
8095 in diagnostics.
8096 * tests/input.at (Torturing the Scanner): Likewise.
8097 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
8098
8099 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
8100
8101 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
8102 the data size is known to be too small and we can't increase it.
8103 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
8104
8105 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
8106
8107 * src/parse-gram.y: Include quotearg.h.
8108 (string_as_id): Quote $1 before using it as a key, since the
8109 lexer no longer quotes it for us.
8110 (string_content): Don't strip quotes, since lexer no longer
8111 quotes it for us.
8112 * src/scan-gram.l: Include quotearg.h.
8113 ("\""): Omit quote.
8114 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
8115 a key, since the rest of the lexer doesn't quote it.
8116 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
8117 * tests/regression.at (Token definitions): Check for backslashes
8118 in token strings.
8119
8120 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
8121 (YYSIZE_T): Define to unsigned long int when using an older compiler.
8122 (yyparse): Revamp code to generate long syntax error message, to
8123 make it easier to translate, and to avoid problems with arithmetic
8124 overflow. Change "virtual memory" to "memory" in diagnostic, since
8125 we don't know whether the memory is virtual.
8126
8127 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8128
8129 * NEWS: Bison-generated C parsers now use the _ macro to
8130 translate strings.
8131 * data/yacc.c (_) [!defined _]: New macro.
8132 All English strings wrapped inside this macro.
8133 * doc/bison.texinfo (Bison Parser): Document _.
8134 * po/POTFILES.in: Include src/parse-gram.c, since it now
8135 includes translateable strings that parse-gram.y doesn't.
8136
8137 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
8138
8139 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
8140 reverting the 2004-10-11 change to this function.
8141 (symbol_check_alias_consistency): Don't call symbol_type_set
8142 if the type name is already correct.
8143 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
8144
8145 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
8146
8147 * tests/regression.at (Token definitions): Don't use a token named
8148 c, as that generates a "#define c ..." that runs afoul of buggy
8149 stdlib.h that uses the identifier c as a member of struct
8150 drand48_data. Problem reported by Horst Wente.
8151
8152 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
8153
8154 * bootstrap: Change translation URL from
8155 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
8156 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
8157 redirection glitches. Problem reported by twlevo@xs4all.nl.
8158
8159 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
8160
8161 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
8162 after operands; POSIX says this isn't portable for the c99 command.
8163
8164 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
8165
8166 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
8167 immediately if a data overrun has occurred; this may help us track
8168 down what may be a spurious failure on MacOS.
8169
8170 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
8171
8172 Respond to problems reported by twlevo@xs4all.nl.
8173
8174 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
8175
8176 * src/vcg.h: Comment fix.
8177 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
8178 (G_CMAX): Change to -1 instead of INT_MAX.
8179
8180 * data/yacc.c (yyparse): Omit spaces before #line.
8181
8182 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
8183
8184 * src/tables.c (state_number_to_vector_number): Put it inside an
8185 "#if 0", since it's not currently used. Problem reported by
8186 Roland McGrath.
8187
8188 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
8189
8190 * src/output.c (escaped_output): Renamed from
8191 escaped_file_name_output, since we now use it for symbol tags as
8192 well. All uses changed.
8193 (symbol_destructors_output, symbol_printers_output):
8194 Escape symbol tags too.
8195 Problem reported by Matyas Forstner in
8196 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
8197
8198 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
8199 not needed.
8200 * src/output.c (user_actions_output, token_definitions_output,
8201 symbol_destructors_output, symbol_printers_output): Likewise.
8202 * src/reader.c (prologue_augment): Likewise.
8203 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
8204
8205 * src/vcg.c (output_edge): Don't quote linestyle arg.
8206 Problem reported by twlevo@xs4all.nl.
8207
8208 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
8209
8210 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
8211 example, reported by Derek M Jones. Also, make the example even
8212 more outrageous, to better illustrate how bad the problem is.
8213
8214 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
8215
8216 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
8217 putsym. Typo reported by Sebastian Piping.
8218
8219 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>

8223 Typos reported by Sebastian Piping via Justin Pence.
8224
8225 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8226
8227 * tests/glr-regression.at (Improper handling of embedded actions
8228 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
8229 embedded actions and $-N in GLR parsers", work around an Autoconf bug
8230 with dollar signs in test names.
8231 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
8232 for a similar reason.
8233
8234 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8235
8236 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
8237 wants to redefine G_VIEW.
8238
8239 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
8240
8241 * src/vcg.c (get_view_str): Remove case for normal_view.

8257
8258 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8259
8260 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
8261 keyword; it's not needed with modern compilers, and it doesn't
8262 affect correctness with older compilers. Suggested by
8263 twlevo@xs4all.nl.
8264
8265 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
8266

8277 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
8278
8279 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
8280 for the benefit of slower hosts. Problem reported by
8281 Nelson H. F. Beebe.
8282
8283 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
8284
8285 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
8286 being defined and not used.
8287 * data/lalr1.cc (yyparse): Likewise.
8288 Use "if (false)" rather than "if (0)".
8289
8290 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
8291
8292 * TODO: Mention that we should allow NUL bytes in tokens.
8293
8294 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
8295
8296 * src/scan-skel.l (<<EOF>>): Don't close standard output.
8297 Problem reported by Hans Aberg.
8298
8299 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
8300
8301 * src/getargs.c (version): Happy new year; update overall
8302 program copyright date from 2004 to 2005.
8303
8304 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
8305 Problem reported by Hans Aberg.
8306 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
8307 (Output file names.): Add a test for the case when standard output
8308 is closed.
8309
8310 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
8311
8312 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
8313 to fix an oversight in the Bison 2.0 manual.
8314
8315 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
8316
8317 * NEWS: Version 2.0. Reformat the existing news items since
8318 1.875, so that related items are grouped together.
8319 * configure.ac (AC_INIT): Bump version to 2.0.
8320 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
8321
8322 * tests/torture.at (Exploding the Stack Size with Alloca): Set
8323 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
8324 otherwise, we're not testing alloca. Unfortunately there's no
8325 simple way to consult HAVE_ALLOCA here.
8326
8327 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
8328 for yymsg, too.
8329
8330 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
8331 hand. This avoids a warning about comparing int to size_t when
8332 GCC warnings are enabled.
8333
8334 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
8335
8336 * NEWS: Bison-generated parsers no longer default to using the
8337 alloca function (when available) to extend the parser stack, due
8338 to widespread problems in unchecked stack-overflow detection.
8339 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
8340 responsibility to set it to a positive value. This lets the user
8341 specify a value that is not a preprocessor constant.
8342 * data/yacc.c (YYMAXDEPTH): Likewise.
8343 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
8344 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
8345 to be a compile-time constant. However, explain the constraints on it.
8346 Also, explain the constraints on YYINITDEPTH.
8347 (Table of Symbols): Explain that alloca is no longer the default.
8348 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
8349 to 1.
8350
8351 * doc/bison.texinfo (Location Default Action): Mention that n must
8352 be zero when k is zero. Suggested by Frank Heckenbach.
8353
8354 2004-12-22 Akim Demaille <akim@epita.fr>
8355
8356 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
8357 (parser::state_type, parser::semantic_type, parser::location_type):
8358 Private, not public.
8359 (parser::parse): Return ints, not bool.
8360 Returning a bool introduces a problem: 0 corresponds to false, and
8361 it seems weird to return false on success. Returning true changes
8362 the conventions for yyparse.
8363 Alternatively we could return void and send an exception.
8364 There is no clear consensus (yet?).
8365 (state_stack, semantic_stack, location_stack): Rename as...
8366 (state_stack_type, semantic_stack_type, location_stack_type): these.
8367 Private, not public.
8368 * tests/c++.at: New.
8369 * tests/testsuite.at, tests/Makefile.am: Adjust.
8370
8371 2004-12-21 Akim Demaille <akim@epita.fr>
8372
8373 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
8374
8375 2004-12-21 Akim Demaille <akim@epita.fr>
8376
8377 Don't impose std::string for filenames.
8378
8379 * data/lalr1.cc (b4_filename_type): New.
8380 (position::filename): Use it.
8381 (parser.hh): Move the inclusion of stack.hh and location.hh below
8382 the user code, so that needed headers for the filename type can be
8383 included first.
8384 Forward declare them before the user code.
8385 * tests/Makefile.am (check-local, installcheck-local): Pass
8386 TESTSUITEFLAGS to the TESTSUITE.
8387
8388 2004-12-20 Akim Demaille <akim@epita.fr>
8389
8390 Use more STL like names: my_class instead of MyClass.
8391
8392 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
8393 (SemanticStack, SemanticType, StateStack, StateType)
8394 (TokenNumberType, Stack, Slice, Traits, Parser::location)
8395 (Parser::value): Rename as...
8396 (location_stack, location_type, rhs_number_type, semantic_stack)
8397 (semantic_type, state_stack, state_type, token_number_type, stack)
8398 (slice, traits, parser::yylloc, parser::yylval): these.
8399
8400 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
8401
8402 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
8403
8404 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
8405 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8406
8407 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
8408
8409 Remove uses of 'short int' and 'unsigned short int'. This raises
8410 some arbitrary limits. It uses more memory but nowadays that's
8411 not much of an issue.
8412
8413 This change does not affect the generated parsers; that's a different
8414 task, as some users will want to conserve memory there.
8415
8416 Ideally we should use size_t to represent all object counts, and
8417 something like ptrdiff_t to represent signed differences of object
8418 counts; but that will require more code-cleanup than I have the
8419 time to do right now.
8420
8421 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
8422 Use size_t, not int or short int, to count objects.
8423 * src/closure.c (nritemset, closure): Likewise.
8424 * src/closure.h (nritemset, closure): Likewise.
8425 * src/nullable.c (nullable_compute): Likewise.
8426 * src/print.c (print_core): Likewise.
8427 * src/print_graph.c (print_core): Likewise.
8428 * src/state.c (state_compare, state_hash): Likewise.
8429 * src/state.h (struct state): Likewise.
8430 * src/tables.c (default_goto, goto_actions): Likewise.
8431
8432 * src/gram.h (rule_number, rule): Use int, not short int.
8433 * src/output.c (prepare_rules): Likewise.
8434 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
8435 errs, reductions): Likewise.
8436 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
8437 Likewise.
8438 * src/tables.c (vector_number, tally, action_number,
8439 ACTION_NUMBER_MINIMUM): Likewise.
8440 * src/output.c (muscle_insert_short_int_table): Remove.
8441
8442 2004-12-17 Akim Demaille <akim@epita.fr>
8443
8444 * data/lalr1.cc: Extensive Doxygenation.
8445 (error_): Rename as...
8446 (error): this, since it is visible to the user.
8447 Adjust callers.
8448 (Parser::message): Now an automatic variable from...
8449 (Parser::yyreport_syntax_error_): here.
8450 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
8451 Parser::error.
8452 * tests/input.at: Escape $.
8453
8454 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
8455
8456 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
8457 Parenthesize rhs to avoid obscure problems with mistakes like
8458 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
8459 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8460 b4_rhs_location): Likewise.
8461 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8462 b4_rhs_location): Likewise.
8463
8464 2004-12-16 Akim Demaille <akim@epita.fr>
8465
8466 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
8467 yacc.c: be sure to stay within yycheck_.
8468 * tests/actions.at: Re-enable C++ tests.
8469
8470 2004-12-16 Akim Demaille <akim@epita.fr>
8471
8472 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
8473 real.
8474
8475 2004-12-16 Akim Demaille <akim@epita.fr>
8476
8477 Use #define to handle the %name-prefix.
8478
8479 * data/glr.c, data/yacc.c: Comment changes.
8480 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
8481 so that one can refer to yylex in the parser file, and have it
8482 renamed, as is the case with other skeletons.
8483
8484 2004-12-16 Akim Demaille <akim@epita.fr>
8485
8486 Move lalr1.cc internals into yy*.
8487
8488 * data/lalr1.cc (semantic_stack_, location_stack_, state_stack_)
8489 (semantic_stack_, location_stack_, pact_, pact_ninf_, defact_)
8490 (pgoto_, defgoto_, table_, table_ninf_, check_, stos_, r1_, r2_)
8491 (name_, rhs_, prhs_, rline_, token_number_, eof_, last_, nnts_)
8492 (empty_, final_, terror_, errcode_, ntokens_)
8493 (user_token_number_max_, undef_token_, n_, len_, state_, nerrs_)
8494 (looka_, ilooka_, error_range_, nerrs_):
8495 Rename as...
8496 (yysemantic_stack_, yylocation_stack_, yystate_stack_)

8504 these.
8505
8506 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
8507
8508 Fix some problems reported by twlevo at xs4all.
8509 * src/symtab.c (symbol_new): Report an error if the input grammar
8510 contains too many symbols. This is better than calling abort() later.
8511 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
8512 (struct node, struct graph):
8513 Rename member expand to stretch. All uses changed.
8514 (struct graph): Remove member layoutalgorithm. All uses removed.
8515 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
8516 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
8517 All uses changed.
8518 (N_STRETCH): Rename from N_EXPAND. All uses changed.
8519
8520 2004-12-15 Akim Demaille <akim@epita.fr>
8521

8523 Add more Doxygen comments.
8524 (symprint_, stack_print_, reduce_print_, destruct_, pop)
8525 (report_syntax_error_, translate_): Rename as...
8526 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
8527 (yypop_, yyreport_syntax_error_, yytranslate_): this.
8528
8529 2004-12-15 Akim Demaille <akim@epita.fr>
8530
8531 * data/lalr1.cc (lex_): Rename as...
8532 (yylex_): this.
8533 Move the trace here.
8534 Take the %name-prefix into account.
8535 Reported by Alexandre Duret-Lutz.
8536
8537 2004-12-15 Akim Demaille <akim@epita.fr>
8538
8539 Simplify the C++ parser constructor.
8540
8541 * data/lalr1.cc (debug_): Rename as...
8542 (yydebug_): so that the parser's internals are always in the yy*
8543 pseudo namespace.
8544 Adjust uses.
8545 (b4_parse_param_decl): Remove the leading comma as it is now only
8546 called as unique argument list.
8547 (Parser::Parser): Remove the constructor accepting a location and
8548 an initial debugging level.
8549 Remove from the other ctor the argument for the debugging level.
8550 (debug_level_type, debug_level, set_debug_level): New.
8551
8552 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
8553 constructor calls.
8554
8555 2004-12-15 Akim Demaille <akim@epita.fr>
8556
8557 Remove b4_root related material: failure experiment
8558 (which goal was to allow to derive from a class).
8559
8560 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
8561 definitions and uses.
8562
8563 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
8564
8565 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
8566 not 2, since it's not portable to subtract 1 from the start of an
8567 array. The new item 0 is never set or used. All uses changed.
8568
8569 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
8570 the default definition of YYLLOC_DEFAULT. Problem reported
8571 by Frank Heckenbach.
8572
8573 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
8574
8575 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
8576 the normal case and one for the error case. Just use the
8577 first one uniformly. Problem reported by Frank Heckenbach.
8578 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
8579 use exactly the same macro in both places.
8580 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
8581 so that the normal-case YYRHSLOC works for the error case too.
8582 All uses changed.
8583 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
8584 (YYLLOC_DEFAULT): Use the same macro as glr.c.
8585 * doc/bison.texinfo (Location Default Action): Don't claim that
8586 we have an array of locations. Use the same macro for both glr
8587 and lalr parsers. Mention YYRHSLOC. Mention what happens when
8588 the index is 0.
8589
8590 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8591
8592 * HACKING: Update email addresses to send announcements to.

8600
8601 * src/scan-skel.l: Include "complain.h", for "fatal".
8602
8603 * src/relation.h (relation_print, relation_digraph):
8604 Relation sizes are of type relation_node, not size_t (this is
8605 merely a doc fix, since the two types are equivalent).
8606 (relation_transpose): Relation sizes are of type relation_node,
8607 not int.
8608 * src/relation.c: Likewise.
8609 (top, infinity): Now of type relation_node, not int.
8610 (traverse, relation_transpose): Use relation_node, not int.
8611
8612 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
8613 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
8614 (yyparse): Remove unused local introduced in 2004-10-25 patch.
8615
8616 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
8617 specifying whether the test should be skipped. Use it tp
8618 specify that the [%defines %skeleton "lalr1.cc"] tests currently
8619 fail on some hosts, and should be skipped.
8620
8621 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8622
8623 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
8624 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
8625 unless otherwise specified below.
8626
8627 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
8628 to allocate kernel_base, kernel_items, kernel_size, since
8629 they needn't be initialized to 0.
8630 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
8631 * src/closure.c (new_closure): Likewise, for itemset.
8632 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
8633 * src/lalr.c (set_goto_map): Likewise, for temp_map.
8634 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
8635 (build_relations): Likewise for edge, states1, includes.
8636 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
8637 * src/reader.c (packgram): Likewise, for ritem, rules.
8638 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
8639 * src/relation.c (relation_digraph): Likewise for VERTICES.
8640 (relation_transpose): Likewise for new_R, end_R.
8641 * src/symtab.c (symbols_token_translations_init): Likewise for
8642 token_translations.
8643 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
8644 (token_actions): Likewise for yydefact, actrow, conflrow,
8645 conflict_list.
8646 (save_column): Likewise for froms[symno], tos[symno].
8647 (goto_actions): Likewise for state_count.
8648 (pack_table): Likewise for base, pos, check.
8649 (tables_generate): Likewise for width.
8650
8651 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
8652 for initial core. Just have a separate core, so we needn't worry
8653 about whether kernel_size and kernel_base are initialized.
8654
8655 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
8656 kernel_size, kernel_items): Remove unnecessary initialization.
8657 * src/conflicts.c (conflicts): Likewise.
8658 * src/derives.c (derives): Likewise.
8659 * src/muscle_tablc (muscle_insert): Likewise.
8660 * src/relation.c (relation_digraph): Likewise.
8661 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
8662 conflrow, conflict_table, conflict_list, table, check):
8663 Likewise.
8664
8665 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
8666 This is because all callers pass unsigned int.
8667 * src/closure.h (new_closure): Likewise.
8668
8669 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
8670 (build_relations): Initialize includes[i] in all cases.
8671 * src/reader.c (packgram): Always initialize rules[ruleno].prec
8672 and rules[ruleno].precsym. Initialize members in order.
8673 * src/relation.c (relation_transpose): Always initialize new_R[i]
8674 and end_R[i].
8675 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
8676
8677 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
8678 conflict_list[0] was always 0, but now it isn't initialized.
8679
8680 * src/table.c (table_grow): When conflict_table grew, the grown
8681 area wasn't cleared. Fix this.
8682
8683 * lib/.cvsignore: Add strdup.c, strdup.h.
8684 * m4/.cvsignore: Add strdup.m4.
8685
8686 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
8687
8688 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
8689 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
8690 GOTO_NUMBER_MAXIMUM, since we occasionally compute
8691 ngotos + 1 without checking for overflow.
8692 (build_relations): Use END_NODE, not -1, to denote end of edges.
8693 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
8694 build_relations): Use goto_number, not int, for goto numbers.
8695 * src/tables.c (save_column, default_goto): Likewise.
8696
8697 2004-11-23 Akim Demaille <akim@epita.fr>
8698
8699 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
8700 of #defining from yystype.
8701 Don't typedef yystype, C++ does not need it.
8702 This lets it possible to forward declare it as union.
8703
8704 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
8705
8706 * bootstrap (gnulib_modules): Add extensions.
8707 Problem reported by Jim Meyering.
8708
8709 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
8710
8711 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
8712 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
8713 src/system.h, src/tables.c: XFREE -> free, to accommodate
8714 recent change to gnulib xalloc.h.
8715 Problem reported by Jim Meyering.
8716
8717 2004-11-17 Akim Demaille <akim@epita.fr>
8718
8719 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
8720
8721 2004-11-17 Akim Demaille <akim@epita.fr>,
8722 Alexandre Duret-Lutz <adl@gnu.org>
8723
8724 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
8725 changes.
8726 (YYCDEBUG): Adjust.
8727 Use it instead of cdebug_.
8728 (Parser::debug_stream, Parser::set_debug_stream): New.
8729 (Parser::symprint_): Define cdebug_ for temporary backward
8730 compatibility.
8731 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
8732 debug_stream ().
8733
8734 2004-11-17 Akim Demaille <akim@epita.fr>
8735
8736 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.

8742
8743 * data/glr.c (yyloc_default): Remove; not used.
8744 Problem reported by Frank Heckenbach.
8745
8746 2004-10-25 Akim Demaille <akim@epita.fr>
8747
8748 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
8749 Introduce another definition to address simple location arrays.
8750 (yyGLRStack): New member: yyerror_range.
8751 (yyrecoverSyntaxError, yyparse): Update it.
8752 (yyrecoverSyntaxError): Use it when shifting the error token to
8753 have an accurate range, equivalent to the one computed by both
8754 yacc.c and lalr1.cc.
8755 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
8756 that column numbers start at column 0, as per GNU Coding
8757 Standards, the others tests, and the doc.
8758 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
8759 Adjust to the above change (first column is 0).
8760 And adjust the location of the "<error>", now covering the whole
8761 line.
8762
8763 2004-10-22 Akim Demaille <akim@epita.fr>
8764 and Paul Eggert <eggert@cs.ucla.edu>
8765
8766 Remove some arbitrary limits on goto numbers and relations.
8767 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
8768 initial values, since they're never used.
8769 (set_goto_map): ngotos is now unsigned, so test for overflow
8770 by seeing whether it wraps around to zero.
8771 * src/lalr.h (goto_number): Now size_t, not short int.
8772 (GOTO_NUMBER_MAXIMUM): Remove.
8773 * src/relation.c (relation_print, traverse, relation_transpose):
8774 Check for END_NODE rather than looking at sign.
8775 * src/relation.h (END_NODE): New macro.
8776 (relation_node): Now size_t, not short int.
8777
8778 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
8779
8780 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
8781 keyword, not an identifier. Problem reported by Baron Schwartz in
8782 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
8783
8784 2004-10-11 Akim Demaille <akim@epita.fr>
8785
8786 * src/symtab.c (symbol_check_alias_consistency): Also check
8787 type names, destructors, and printers.
8788 Reported by Alexandre Duret-Lutz.
8789 Recode the handling of associativity and precedence in terms
8790 of symbol_precedence_set.
8791 Accept no redeclaration at all, not even equal to the previous
8792 value.
8793 (redeclaration): New.
8794 Use it to factor redeclaration complaints.
8795 (symbol_make_alias): Don't set the type of the alias, let
8796 symbol_check_alias_consistency do it as for other features.
8797 * src/symtab.h (symbol): Add new member prec_location, and
8798 type_location.
8799 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
8800 * tests/input.at (Incompatible Aliases): New.
8801
8802 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
8803
8804 .cvsignore fixes to accommodate gnulib changes,
8805 and the practice of naming build directories "_build".
8806 * .cvsignore: Add "_*". Sort.
8807 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
8808 * m4/.cvsignore: Add "*_gl.m4".
8809
8810 2004-10-06 Akim Demaille <akim@epita.fr>
8811
8812 * src/parse-gram.y (add_param): Fix the truncation of trailing
8813 spaces.
8814
8815 2004-10-05 Akim Demaille <akim@epita.fr>
8816
8817 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8818 whether the reducion was empty or not. This leaves room to
8819 improve the use of YYLLOC_DEFAULT in such a case.
8820 lalr1.cc is still experimental, so changing this is acceptable.
8821 And finally, there are probably not many users who changed the
8822 handling of locations in GLR, so changing is admissible too.
8823
8824 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
8825 empty reduction, set @$ to an empty location ending the previously
8826 stacked symbol.
8827 Adjust uses to make sure the code is triggered on empty
8828 reductions.
8829 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
8830 expected output: empty reductions have empty locations.
8831
8832 2004-09-29 Akim Demaille <akim@epita.fr>
8833
8834 * data/lalr1.cc: Move towards a more standard C++ coding style
8835 for templates: Class < T > -> Class<T>.
8836
8837 2004-09-29 Akim Demaille <akim@epita.fr>
8838
8839 * data/lalr1.cc: Reinstall the former ctor, for sake of
8840 compatibility, but warn it will be removed.
8841 Move towards a more standard C++ coding style (i.e., type *var ->
8842 type* var).
8843
8844 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
8845
8846 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
8847 since it's less likely to work if NULs are involved in the future.
8848
8849 2004-09-27 Akim Demaille <akim@epita.fr>
8850
8851 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
8852
8853 2004-09-27 Akim Demaille <akim@epita.fr>
8854
8855 * data/lalr1.cc (b4_parse_param_decl_1): New.
8856 (b4_parse_param_decl): Use it to have different names between attribute
8857 and argument names.
8858 (b4_cc_constructor_call): Likewise.
8859
8860 2004-09-24 Akim Demaille <akim@epita.fr>
8861
8862 * src/parse-gram.y (add_param): Strip the leading and trailing
8863 blanks from a formal argument declaration.
8864 (YY_LOCATION_PRINT): New.
8865
8866 2004-09-24 Akim Demaille <akim@epita.fr>
8867
8868 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
8869 after the location.
8870
8871 2004-09-24 Akim Demaille <akim@epita.fr>
8872
8873 * doc/bison.texinfo (Table of Symbols): Sort.
8874
8875 2004-09-21 Akim Demaille <akim@epita.fr>
8876
8877 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
8878 the useless parentheses.
8879 Suggested by Paul Eggert.
8880
8881 2004-09-20 Akim Demaille <akim@epita.fr>
8882
8883 Let the initial-action act on the look-ahead, and use it for the
8884 "initial push" (corresponding to an hypothetical beginning-of-file).
8885 And let lalr1.cc honor %initial-action.
8886
8887 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
8888 example.
8889 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
8890 (Parser::Parser): Remove the ctor that used to initialize it.
8891 (Parser::parse): Like in the other skeletons, issue the "starting
8892 parse" message before any action.
8893 Honor %initial-action.
8894 Initialize the stacks with the lookahead.
8895 * data/yacc.c: Let $$ and @$ in %initial-action designate the
8896 look-ahead.
8897 Push them in the stacks.
8898 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
8899
8900 2004-09-20 Akim Demaille <akim@epita.fr>
8901
8902 * doc/bison.texinfo (Initial Action Decl): New.
8903
8904 2004-09-20 Akim Demaille <akim@epita.fr>
8905
8906 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
8907 clearer criterion to define it.
8908 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
8909 When reducing on an empty RHS, use the latest stacked location as
8910 location.
8911 yylloc is not always available.
8912 * data/glr.c: Likewise.
8913 Also, honor initial-actions.
8914
8915 2004-09-20 Akim Demaille <akim@epita.fr>
8916
8917 * data/yacc.c (YY_LOCATION_PRINT): New.
8918 Define when we know YYLTYPE's structure, i.e., when the default
8919 YYLLOC_DEFAULT is used.
8920 * data/c.m4 (b4_yysymprint_generate): Use it.
8921 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
8922 value of the result.
8923 (error_start_): Replace with...
8924 (error_range_): this location array.
8925 This allows to replace code relying on the implementation of
8926 locations by portable code.
8927 * data/yacc.c (yylerrsp): Replace with...
8928 (yyerror_range): this.
8929 Every time a token is popped, update yyerror_range[0], to have an
8930 accurate location for the error token.
8931 * data/glr.c (YY_LOCATION_PRINT): New.
8932 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
8933 deference a pointer.
8934 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
8935 report the location in %printers.
8936
8937 * src/scan-skel.l: Instead of abort, report error messages to ease
8938 understanding skeleton scanning failures.
8939
8940 2004-09-16 Akim Demaille <akim@epita.fr>
8941
8942 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
8943 (iterator, const_iterator): these, to be more in the C++ spirit.
8944 Also, return reverse iterators so that when displaying the stack
8945 we display its bottom first.
8946 (Parser::stack_print_, Parser::reduce_print_): Match the messages
8947 from yacc.c.
8948 We should probably use vector here though.
8949
8950 2004-09-16 Akim Demaille <akim@epita.fr>
8951
8952 Have more complete shift traces.
8953
8954 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
8955 to report Shifts instead of ad hoc YYDPRINTF invocations,
8956 including for the error token.
8957 * data/lalr1.cc (symprint_): Output the location.
8958 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
8959 output the location within the %printer.
8960 Activate GLR tests, at least to make sure they compile properly.
8961 They still don't pass though.
8962 * tests/calc.at: Adjust expect verbose output, since now "Entering
8963 state..." is on a different line than the "Shifting" message.
8964
8965 2004-09-08 Akim Demaille <akim@epita.fr>
8966
8967 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
8968 Bison directive from the Bison file to the invocation of this
8969 macro, so that these directives are passed to
8970 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8971 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8972 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8973 the extra Bison directives instead of the whole series.
8974 Change the grammar so that there are recoverable errors, and
8975 unrecoverable errors. Now we can have the parser give up before
8976 consuming the whole input. As a result we now can observe that
8977 the lookahead is freed when needed.
8978 Change the parser source to parse argv[1] instead of a hard coded
8979 string.
8980 Simplify yylex, and give a value and location to EOF.
8981 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8982 passed directives already coded in the file.
8983 Add some tests to check the location of "error".
8984 For some tests, the C++ parser is correct, and not yacc.c.
8985 For other tests, they provide different, but unsatisfying, values,
8986 so keep the C++ value so that at least one parser is "correct"
8987 according to the test suite.
8988 (Actions after errors): Remove, this is subsumed by the
8989 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
8990
8991 2004-09-06 Akim Demaille <akim@epita.fr>
8992
8993 * data/lalr1.cc: Adjust the indentation of the labels.
8994 (Parser::pop): New.
8995 Use it.
8996
8997 2004-09-06 Akim Demaille <akim@epita.fr>
8998
8999 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
9000 argument, an informative message.
9001 Call YY_SYMBOL_PRINT.
9002 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
9003 * data/lalr1.cc (destruct_): Likewise.
9004 In addition, no longer depend on b4_yysymprint_generate and
9005 b4_yydestruct_generate to generate these functions, do it "by
9006 hand".
9007
9008 2004-09-03 Akim Demaille <akim@epita.fr>
9009
9010 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
9011 invoked, yydestruct the lookahead.
9012 * tests/calc.at (Calculator $1): Update the expected lengths of
9013 traces: there is an added line for the discarded lookahead.
9014 * doc/bison.texinfo (Destructor Decl): Some rewording.
9015 Define "discarded" symbols.
9016
9017 2004-09-02 Akim Demaille <akim@epita.fr>
9018
9019 * data/lalr1.cc (translate_, destruct_): No reason to be static.
9020
9021 2004-09-02 Akim Demaille <akim@epita.fr>
9022
9023 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
9024 (YYDSYMPRINTF): Rename as...
9025 (YY_SYMBOL_PRINT): this.
9026 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
9027 two.
9028 Use it instead of direct symprint_ calls.
9029 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
9030 one.
9031
9032 2004-09-02 Akim Demaille <akim@epita.fr>
9033
9034 * data/lalr1.cc (b4_yysymprint_generate): New.
9035 (symprint_): New member function, defined when YYDEBUG.
9036 Use it consistently instead of token/nterm debugging output by
9037 hand.
9038 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
9039 %printer calls to use cdebug_ when using lalr1.cc.
9040
9041 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9042
9043 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
9044 with #ifdef YYDEBUG.
9045
9046 2004-08-26 Akim Demaille <akim@epita.fr>
9047
9048 * doc/bison.texinfo (Implementing Loops): Rename as...
9049 (Implementing Gotos/Loops): this.
9050
9051 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
9052
9053 Adjust to latest gnulib.
9054 * bootstrap (gnulib_modules): Add xalloc-die.
9055 Set LC_ALL=C so that file names sort consistently.
9056 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9057 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9058 uintmax_t.m4, ulonglong.m4.
9059 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9060 po.m4 since we are now using _gl.m4 instead.
9061
9062 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9063
9064 * src/scan-action.l: Remove. Scanning of semantic actions is
9065 handled in scan-gram.l.
9066
9067 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
9068
9069 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
9070
9071 * src/location.h (struct): The file member is a uniqstr.
9072 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9073
9074 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9075
9076 Fix bug with non-%union parsers that have printers or destructors,
9077 which led to a Bison core dump. Reported by Peter Fales in
9078 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9079
9080 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9081 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9082 not to our own type.
9083 * src/output.c (symbol_destructors_output, symbol_printers_output):
9084 Don't assume %union.
9085 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9086 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9087 UNION-FLAG. All callers changed.
9088 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9089 Use type char, not unsigned int, when declaring an array of char;
9090 this lets us remove a cast.
9091 (Printers and Destructors): Add non-%union test cases.
9092
9093 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9094
9095 * doc/bison.texinfo: Minor editorial changes, mostly to the new
9096 GLR writeups. E.g., avoid frenchspacing and the future tense,
9097 change "lookahead" to "look-ahead", and change "wrt" to "with
9098 respect to".
9099
9100 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9101
9102 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
9103 New sections, split off from the GLR Parsers section. Put the new
9104 Simple GLR Parser near the start of the GLR section, for clarity.
9105 Rewrite connective text.
9106
9107 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
9108
9109 * doc/bison.texinfo (Simple GLR Parsers): New section.
9110
9111 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9112
9113 * NEWS, TODO, doc/bison.texinfo:
9114 Use "look-ahead" instead of "lookahead", to be consistent.
9115 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
9116 while we're fixing "look-ahead".
9117 * src/conflicts.c (shift_set): Renamed from shiftset.
9118 (look_ahead_set): Renamed from lookaheadset.
9119 * src/print.c: Likewise.
9120 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
9121 name for "lookahead".

9141
9142 Don't assume the C++ compiler takes the same arguments as the C compiler
9143 (trivial change).
9144 * configure.ac (O0CXXFLAGS): New var.
9145 * tests/atlocal.in (CXXFLAGS): Use it.
9146
9147 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
9148
9149 Fix some "make check" problems with C++ reported by
9150 Albert Chin-A-Young for Tru64 C++ in this thread:
9151 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
9152
9153 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
9154 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9155 Output to a .cc file for C++, not to a .c file.
9156 * tests/calc.at (AT_CHECK_CALC): Likewise.
9157 * tests/regression.at (AT_CHECK_DANCER): Likewise.

9164
9165 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
9166
9167 Spent a few hours checking out which prerequisite versions the
9168 current sources actually require. I went all the way back to
9169 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9170 a seemingly endless set of combinations of versions more recent
9171 than that. The bottom line is that the current sources require
9172 fairly recent versions of the build tools, and it'll be some work
9173 to change this.
9174 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9175 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9176 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9177 Add comments explaining why those particular versions are
9178 currently needed.
9179
9180 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
9181 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
9182 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
9183
9184 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
9185 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
9186
9187 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9188
9189 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
9190 0.11.5. Suggested by Bruno Haible.
9191 * bootstrap: Remove gettext version checking.
9192
9193 * doc/bison.texinfo (Decl Summary): Also mention that %union
9194 can depend on prerequisite types. Problem reported by Tim
9195 Van Holder.
9196
9197 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9198
9199 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
9200 * README-alpha: Don't tell people not to package this.
9201
9202 * bootstrap: Don't assume $(...) works; use `...` instead.
9203 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
9204 gettext better.
9205
9206 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
9207 put into the -d output file, and mention what to do if YYSTYPE is
9208 defined as a macro.
9209
9210 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9211
9212 Undo change made earlier today: it caused autopoint to not bring
9213 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9214 autopoint's.
9215
9216 * bootstrap: Check that gettext version matches what's in
9217 configure.ac. Warn users to ignore robots.txt ERROR 404.
9218 * bootstrap: Undo today's earlier change (logged below).
9219 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
9220
9221 The gettext version checking is causing more trouble than it's
9222 curing; remove it. Problem reported by Paul Hilfinger.
9223
9224 * bootstrap: Issue a warning that one can expect a message
9225 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
9226 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
9227
9228 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
9229
9230 Ensure that the C++ compiler used for testing actually works on a
9231 simple test program; if not, skip the C++-related tests. Problem
9232 reported by Vin Shelton in:
9233 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
9234
9235 * m4/cxx.m4: New file.

9238 * tests/local.at (AT_COMPILE_CXX): Use it.
9239
9240 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
9241
9242 * data/glr.c (yylloc): Output this macro even if locations are not
9243 being generated, as the GLR parser needs it even in that case.
9244 Problem reported by Troy A. Johnson
9245 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
9246
9247 * configure.ac (AC_INIT): Update to 1.875e.
9248
9249 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
9250
9251 * NEWS: Version 1.875d.
9252 * configure.ac (AC_INIT): Likewise.
9253 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
9254
9255 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
9256 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
9257 lalr1.cc runs afoul of the first, and the last two are no longer
9258 supported by GCC 3.4.0.
9259 * README: Mention GNU m4 1.4 or later; mention m4 patches.
9260 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
9261
9262 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
9263
9264 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

9273
9274 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
9275 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
9276 character and string literals.
9277 (unexpected_end): New function.
9278 (unexpected_eof): Use it.
9279 (unexpected_newline): New function.

9284
9285 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
9286 Fix typo by replacing $1 with $option.
9287 Remove more 'intl'-related files.
9288 Don't DEFUN AM_INTL_SUBDIR twice.
9289
9290 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
9291 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
9292 strtoul.c.
9293 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
9294 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
9295 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
9296 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
9297 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
9298 * src/.cvsignore: Add *.output.
9299
9300 * src/parse-gram.y: Put copyright notice inside %{ %} so it
9301 gets copied to the output file.
9302
9303 2004-04-28 Paul Eggert <eggert@twinsun.com>
9304
9305 Get files from the gnulib and po repositories, instead of relying
9306 on them being in our CVS. Upgrade to latest versions of gnulib
9307 and Automake.
9308
9309 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
9310 * bootstrap: Bootstrap from gnulib and po repositories.
9311 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
9312 * README-cvs: Document these changes. Remove version numbers from
9313 mentions of build tools, since they change so often. Mention Flex.
9314
9315 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
9316 (gl_USE_SYSTEM_EXTENSIONS): Add.
9317 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
9318 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
9319 does this for us.
9320 (AC_ISC_POSIX): Remove; we no longer support this
9321 ancient OS, as it gets in the way of latest Autoconf & gnulib.
9322 (AC_HEADER_STDC): Remove: we now assume C89 or better.
9323 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
9324 Do not check for C89 headers, except for locale.h which is used
9325 by the Yacc library and must port to K&R hosts.
9326 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
9327 Do not check for C89 functions, except for setlocale which is
9328 used by the Yacc library.
9329 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
9330 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
9331 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,

9333 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
9334 AM_GNU_GETTEXT): Remove; now done by:
9335 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
9336 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
9337 for us.
9338
9339 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
9340 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
9341 Define to empty, as gnulib.mk will do the rest for us.
9342 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
9343 for us.
9344 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
9345 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
9346
9347 * src/files.c: Include gnulib's xstrndup.h.
9348
9349 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
9350 (REALLOC): Use xnrealloc, for likewise.
9351 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
9352 (strnlen, memrchr): Remove decls; functions no longer used.
9353 Include <stpcpy.h>.
9354
9355 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

9375 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
9376 Remove, as these files are now generated automatically
9377 by bootstrap or automake.
9378
9379 * po/ChangeLog: Remove: all but one entry was a duplicate
9380 of this file, and I moved that 2000-11-02 entry here.
9381
9382 * config/.cvsignore: Add Makefile, depcomp, install-sh.

9399 * src/.cvsignore: Remove *_.c.
9400
9401
9402 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
9403 support it. (The latest stable gzip doesn't.)
9404
9405 2004-04-27 Paul Eggert <eggert@twinsun.com>
9406
9407 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
9408 case, as stos_ is now used by destructors due to the 2004-02-09
9409 change.
9410
9411 Remove more K&R C support.
9412 * lib/libiberty.y (PARAMS): Remove. All uses removed.
9413 * lib/subpipe.c (errno): Remove decl.
9414 Include <stdlib.h> unconditionally.
9415 (EXIT_FAILURE): Remove macro.
9416 * src/complain.c (vfprintf, strerror): Remove.
9417 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
9418 unconditionally.
9419 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
9420 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
9421 (strchr, strspn, memchr): Remove decls.
9422 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
9423 unconditionally. Do not declare perror.
9424 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
9425 unconditionally.
9426
9427 * src/complain.c (_): Remove useless defn, as system.h defines this.

9430 with latest obstack.h.
9431 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
9432 to procedure types, as obstack.h now does that for us.

9434
9435 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
9436 so that this include file can stand alone.
9437 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
9438 does this now. Include subpipe.h first after config.h, to
9439 test whether it can stand alone.
9440
9441 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
9442 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
9443 unused declaration.
9444
9445 * tests/synclines.at (%union synch line): Put a dummy member in
9446 the union, because empty unions aren't allowed in C. Caught
9447 by GCC 3.4.0.
9448
9449 2004-04-13 Jim Meyering <jim@meyering.net>
9450
9451 * src/conflicts.c (conflicts_print): Correct format string typo:

9499 Add %expect-rr rule.
9500
9501 * src/scan-gram.l: Recognize %expect-rr.

9511 for GLR parsers.
9512 Use expected_sr_conflicts in place of expected_conflicts.
9513 Warn if expected_rr_conflicts used in non-GLR parser.
9514
9515 * doc/bison.texinfo: Add documentation for %expect-rr.
9516
9517 2004-03-08 Paul Eggert <eggert@gnu.org>
9518
9519 Add support for hex token numbers. Suggested by Odd Arild Olsen in
9520 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
9521
9522 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
9523 in lalr1.cc.
9524 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
9525 * src/scan-gram.l (scan_integer): New function.
9526 ({int}): Use it.
9527 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
9528 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
9529 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
9530 Say "long int", not "long", for uniformity with GNU style.
9531
9532 2004-02-25 Paul Eggert <eggert@twinsun.com>
9533
9534 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
9535 compilers. This fixes a problem with Intel's C++ compiler being
9536 chatty, reported by Guido Trentalancia in
9537 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
9538
9539 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
9540
9541 Support %destructor and merge error locations in lalr1.cc.
9542
9543 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
9544 (Parser::stos_): Define unconditionally.
9545 (Parser::destruct_): New method. Generate its body with
9546 b4_yydestruct_generate.
9547 (Parser::error_start_): New attribute.
9548 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
9549 token which are discarded.
9550 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
9551 error_start_ when erroneous token are discarded.
9552 (Parser::parse) <yyerrlab1>: Compute the location of the error
9553 token so that it covers all the discarded tokens.
9554 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
9555 it can be called with `%skeleton "lalr1.cc"', and do that.
9556
9557 2004-02-02 Paul Eggert <eggert@twinsun.com>
9558
9559 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
9560 $(top_srcdir)/lib and ../lib. This fixes a bug reported
9561 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
9562 There's no need to mention top_builddir since Automake does that
9563 for us.
9564 (INCLUDES): Remove, as Automake says it's obsolescent.
9565 Contents migrated into AM_CPPFLAGS as described above.
9566 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
9567
9568 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9569
9570 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
9571 (yyreportSyntaxError): Handle case where lookahead token is
9572 YYEMPTY.
9573
9574 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9575
9576 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
9577 resulting parsers are compilable with C++.
9578
9579 2003-12-23 Paul Eggert <eggert@twinsun.com>
9580
9581 * config/depcomp, config/install-sh: Sync with Automake 1.8.
9582 * src/output.c (output_skeleton): Rename local var.
9583 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
9584 Bison tokens, as this runs afoul of the 2003-10-07 change that
9585 disallowed NUL bytes in character constants or string literals.
9586
9587 * tests/local.at: Require Autoconf 2.59's Autotest.
9588 * tests/testsuite.at: Don't include local.at, since we now assume
9589 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
9590 including it.
9591 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
9592 multiple inclusion warnings.
9593
9594 2003-12-02 Akim Demaille <akim@epita.fr>
9595
9596 * doc/bison.texinfo (How Can I Reset the Parser): More about start
9597 conditions.
9598 From Bruno Haible.
9599
9600 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
9601
9602 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
9603
9604 2003-10-07 Paul Eggert <eggert@twinsun.com>
9605
9606 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
9607 if testsuite doesn't exist.
9608
9609 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
9610 literals, unfortunately.
9611 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
9612 Complain about NUL bytes in character constants or string literals.
9613
9614 2003-10-05 Paul Eggert <eggert@twinsun.com>
9615
9616 * NEWS: Don't document %no-default-prec, as it's still
9617 too experimental.
9618 * doc/bison.texinfo: Document %no-default-prec only if
9619 the defaultprec flag is set. Normally it's not.
9620
9621 2003-10-04 Paul Eggert <eggert@twinsun.com>
9622
9623 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
9624 non-modifiable lvalue, instead of a modifiable one.
9625 * doc/bison.texinfo (Actions): Document that $$ can
9626 be assigned to. Do not claim that $$ and $N are
9627 array element references: user code should not rely on this.
9628
9629 2003-10-01 Paul Eggert <eggert@twinsun.com>
9630
9631 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
9632 (grammar_declaration): Use it.
9633 * src/scan-gram.l: New token %no-default-prec.
9634 * tests/conflicts.at: Revamp tests to use %no-default-prec.
9635 * NEWS, doc/bison.texinfo: Document the above.
9636
9637 2003-10-01 Akim Demaille <akim@epita.fr>
9638
9639 VCG no longer supports long_straight_phase.
9640
9641 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
9642 * src/print_graph.c (print_graph): Adjust.
9643
9644 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
9645 and Paul Eggert <eggert@twinsun.com>
9646

9657
9658 2003-09-30 Paul Eggert <eggert@twinsun.com>
9659
9660 * tests/testsuite.at: Include local.at, not input.at, fixing
9661 a typo in the 2003-08-25 patch.
9662
9663 2003-08-27 Akim Demaille <akim@epita.fr>
9664
9665 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
9666 GCC warnings.
9667
9668 2003-08-26 Akim Demaille <akim@epita.fr>
9669
9670 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
9671 "<\#" to avoid magic from Gnus when posting parts of this script.
9672
9673 2003-08-26 Akim Demaille <akim@epita.fr>
9674
9675 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
9676 (Parser::parse): here.
9677 Adjust: nerrs and errstatus is now replaced by...
9678 (Parser::nerrs_, Parser::errstatus_): New.

9685 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
9686
9687 2003-08-25 Akim Demaille <akim@epita.fr>
9688
9689 When reducing initial empty rules, Bison parser read an initial
9690 location that is not defined. This results in garbage, and that
9691 affects Bison's own parser. Therefore we need (i) to extend Bison
9692 to support a means to initialize this location, and (ii) to use
9693 this CVS Bison to fix CVS Bison's parser.
9694
9695 * src/reader.h, reader.c (epilogue_augment): Remove, replace
9696 with...
9697 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
9698 * src/parse-gram.y: Adjust.
9699 (%initial-action): New.
9700 (%error-verbose): Since we require CVS Bison, there is no reason
9701 not to use it.
9702 * src/scan-gram.l: Adjust.
9703 * src/Makefile.am (YACC): New, to make sure we use our own parser.
9704 * data/yacc.c (yyparse): Use b4_initial_action.
9705
9706 2003-08-25 Akim Demaille <akim@epita.fr>
9707
9708 * doc/bison.texinfo: Don't promote stdout for error messages.
9709
9710 2003-08-25 Akim Demaille <akim@epita.fr>
9711
9712 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
9713 From Alexandre Duret-Lutz.
9714
9715 2003-08-25 Akim Demaille <akim@epita.fr>
9716
9717 Version 1.875c.
9718
9719 2003-08-25 Akim Demaille <akim@epita.fr>
9720
9721 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
9722 Use them.
9723
9724 2003-08-25 Akim Demaille <akim@epita.fr>
9725
9726 * data/lalr1.cc (Parser::reduce_print_): New.
9727 Use it.
9728
9729 2003-08-25 Akim Demaille <akim@epita.fr>
9730
9731 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
9732 error recovery loops. This patch is based on
9733 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
9734 Also, augment the similarity between lalr1.cc and yacc.c.
9735 Note: the locations of error recovery rules are not correct yet.
9736
9737 * data/lalr1.cc: Comment changes to augment the similarity between
9738 lalr1.cc and yacc.c.
9739 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
9740 (yyerrlab1): Remove, but where it used to be (now the bottom part of
9741 yyerrlab), when hitting EOF, pop the whole stack here instead of
9742 merely falling thru the default error handling mechanism.
9743 (yyerrorlab): New label, with the old contents of YYERROR,
9744 plus the following change: pop the stack of rhs corresponding
9745 to the production that invoked YYERROR. That is how Yacc
9746 behaves (required by POSIX).
9747 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
9748 fail.
9749
9750 2003-08-25 Akim Demaille <akim@epita.fr>
9751
9752 Tune local.at so that people can "autom4te -l autotest calc.at -o
9753 calc" for instance, to extract a sub test suite.
9754
9755 * tests/testsuite.at: Move the initialization, Autotest version
9756 requirement, and AT_TESTED invocation into...
9757 * tests/local.at: here.
9758 * tests/testsuite.at: Include it for compatibility with Autoconf
9759 2.57.
9760 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
9761 be ignore.
9762
9763 2003-08-04 Paul Eggert <eggert@twinsun.com>
9764
9765 Rework code slightly to avoid gcc -Wtraditional warnings.
9766 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
9767 The returned value is now stored in *YY0. All callers changed.
9768 * src/output.c (merge_output): Adjust to the above change.
9769
9770 2003-07-26 Paul Eggert <eggert@twinsun.com>
9771
9772 * data/glr.c (YYASSERT): New macro.
9773 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
9774 yyresolveStates, yyprocessOneStack):
9775 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
9776 Derived from a suggestion by Frank Heckenbach.
9777
9778 2003-07-25 Paul Eggert <eggert@twinsun.com>
9779
9780 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
9781 for portability to K&R C (after ansi2knr, presumably). See
9782 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
9783 by Frank Heckenbach, though I have omitted the structure-initialization
9784 part of his glr-knr.diff patch since I recall that the Portable
9785 C Compiler didn't require that change.
9786
9787 Let the user specify how to allocate and free memory.
9788 Derived from a suggestion by Frank Heckenbach in
9789 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
9790 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
9791 All uses of free, malloc, realloc changed to use these macros,
9792 and unnecessary casts removed.
9793 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
9794
9795 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
9796
9797 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
9798 use s.empty() rather than s == "" to test for empty string; see
9799 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
9800 (trivial change)
9801
9802 2003-06-25 Akim Demaille <akim@epita.fr>
9803
9804 * config/depcomp, config/install-sh: Update from masters.
9805
9806 2003-06-20 Paul Eggert <eggert@twinsun.com>
9807
9808 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
9809 and return properly parenthesized result.
9810 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
9811 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
9812 Remove unnecessary parentheses from uses.
9813 * doc/bison.texinfo (Location Default Action): Describe the
9814 conventions for parentheses.
9815
9816 2003-06-19 Paul Eggert <eggert@twinsun.com>
9817
9818 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
9819 yyreportTree): Do not assume that size_t is the same width as int,
9820 when printing sizes. Print sizes using an unsigned format.
9821 Problem reported by Frank Heckenbach in
9822 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
9823
9824 Port to Forte Developer 7 C compiler.
9825 * data/glr.c (struct YYLTYPE): If locations are not being used,
9826 declare a single dummy member, as empty structs do not conform
9827 to the C standard.
9828 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
9829 the Forte Developer 7 C compiler complains that end-of-loop
9830 code is not reached.
9831
9832 2003-06-17 Paul Eggert <eggert@twinsun.com>
9833
9834 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
9835 avoid warnings from picky compilers about redefinition of PARAMS.
9836
9837 2003-06-17 Paul Eggert <eggert@twinsun.com>
9838
9839 Version 1.875b.
9840
9841 * NEWS: Document 1.875b.
9842
9843 * lib/bbitset.h: Do not include config.h; that's the includer's job.
9844 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
9845 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
9846 Don't use 'index' in comments, as it's a builtin fn on some hosts.
9847 * lib/bitset_stats.c: Include gettext.h unconditionally, as
9848 per recent gettext manual's suggestion.
9849 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
9850 Use prototypes, not old-style definitions.
9851 * lib/lbitset.c (lbitset_unused_clear): Likewise.
9852 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
9853 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
9854 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

9857 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
9858 vbitset_or_and_cmp, vbitset_copy): Likewise.

9864 (ATTRIBUTE_UNUSED): Define unconditionally.
9865

9870 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
9871 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
9872 from libbitset.
9873
9874 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
9875 `How Can I Reset @code{yyparse}', since texinfo does not allow
9876 arbitrary @ in node names.
9877
9878 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
9879 shouldn't be needed according to the gettext 0.12.1 documentation
9880 but which seem to be needed anyway: codeset.m4 glibc21.m4
9881 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
9882 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

9887
9888 Upgrade to CVS gnulib.
9889 * stdbool_.h: File renamed from stdbool.h.in.
9890 * configure.ac (AM_STDBOOL_H): Invoke this instead of
9891 AC_HEADER_STDBOOL.
9892 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
9893 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
9894 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
9895 (MOSTLYCLEANFILES): New var.
9896 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
9897 (stdbool.h): New rule.
9898 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
9899 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
9900 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
9901 m4/quote.m4: Upgrade to today's gnulib.
9902
9903 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
9904 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
9905 the tests right now.
9906 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
9907 yyerror are declared before use; C99 requires this.
9908
9909 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9910
9911 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
9912 first.
9913 (yyrecoverSyntaxError): Correct the logic for setting and testing
9914 yyerrState.
9915 Correct comment on handling EOF.
9916 Allow states with only a default reduction, rather than failing
9917 (I can't quite reconstruct why these were not allowed before).
9918
9919 Fixes to avoid problem that $-N rules in GLR parsers can cause
9920 buffer overruns, corrupting state.
9921
9922 * src/output.c (prepare_rules): Output max_left_semantic_context
9923 definition.
9924 * src/reader.h (max_left_semantic_context): New variable declaration.
9925 * src/scan-gram.l (max_left_semantic_context): Define.
9926 (handle_action_dollar): Update max_left_semantic_context.
9927 * data/glr.c (YYMAXLEFT): New definition.
9928 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
9929 (yyresolveAction): Ditto.
9930
9931 Fixes to problems with location handling in GLR parsers reported by
9932 Frank Heckenbach (2003/06/05).
9933
9934 * data/glr.c (YYLTYPE): Make trivial if locations not used.
9935 (YYRHSLOC): Add parentheses, and define only if locations used.
9936 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
9937 locations not used.
9938 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
9939 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
9940
9941 * tests/cxx-type.at: Exercise location information; update tests
9942 to differentiate output with and without locations.
9943 Remove forward declarations of yylex and yyerror---caused errors
9944 because default YYLTYPE not yet defined.
9945 Change semantic actions to compute strings, rather than printing
9946 them directly (to test proper passing of semantics values). Change
9947 output to prefix notation and update test data and expected results.
9948 (yylex): Track locations.
9949 (stmtMerge): Return value rather than printing, and include arguments
9950 in value.

9953
9954 Avoid warnings generated by GCC 2.95.4 when Bison is
9955 configured with --enable-gcc-warnings.
9956 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
9957 yy::]b4_parser_class_name[::translate_,
9958 yy::Stack::operator[] (unsigned),
9959 yy::Stack::operator[] (unsigned) const,
9960 yy::Slice::operator[] (unsigned),
9961 yy::Slice::operator[] (unsigned) const):
9962 Rename local vars to avoid warnings.
9963 * tests/glr-regression.at (Improper handling of embedded actions
9964 and $-N in GLR parsers): Remove unused local variable from yylex.
9965 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
9966 (void) as arg when not pure, since we now assume C89 when building
9967 Bison. Pacify GCC by using parameter.
9968
9969 2003-06-02 Paul Eggert <eggert@twinsun.com>
9970
9971 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
9972 yy::Location::lines, yy::Location::columns): Rename arguments
9973 to avoid shadowing; this removes a warning generated by GCC 3.3.
9974
9975 2003-06-01 Paul Eggert <eggert@twinsun.com>
9976
9977 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
9978 to g++, as GCC 3.3 complains if you do it.
9979 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
9980 everything that WARNING_CFLAGS has, except omit warnings
9981 not suitable for C++.
9982 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
9983 * tests/atlocal.in (CXXFLAGS): New var.
9984 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
9985
9986 Fix a GLR parser bug I reported in February; see
9987 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
9988 The problem was that GLR parsers did not conform to the C standard,
9989 because actions like { $1 = $2 + $3; } expanded to expressions
9990 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9991 to a local variable. The C standard says that expressions
9992 like (var = f ()) + (var = f ()) have undefined behavior.
9993 Another problem was that GCC sometimes issues warnings that
9994 yyfill and its parameters are unused.
9995
9996 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9997 as possibly unused.
9998 (yyfill): New function.
9999 (YYFILL): Use it.
10000 (yyuserAction): Change type of yynormal to bool, so that it matches
10001 the new yyfill signature. Mark it as possibly unused.
10002
10003
10004 Follow up on a bug I reported in February, where a Bison-generated
10005 parser can loop. Provide a test case and a fix for yacc.c. I
10006 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10007 The original bug report is in:
10008 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
10009
10010 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10011 macro's size was becoming unwieldy.
10012 (yyerrlab): Do not discard an empty lookahead symbol, as this
10013 might destroy garbage.
10014 (yyerrorlab): New label, with the old contents of YYERROR,
10015 plus the following change: pop the stack of rhs corresponding
10016 to the production that invoked YYERROR. That is how Yacc
10017 behaves, and POSIX requires this behavior.
10018 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10019 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10020 Define 'alarm' to do nothing if unistd.h is not available.
10021 Add a new rule "exp: '-' error;" to test the above change to
10022 data/yacc.c. Use 'alarm' to abort any test taking longer than
10023 10 seconds, as it's probably looping.
10024 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10025 Also, the new yacc.c generates two fewer diagnostics for an
10026 existing test.
10027
10028 2003-05-24 Paul Eggert <eggert@twinsun.com>
10029
10030 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10031 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10032 This fixes a problem reported by John Bowman when the Compaq/HP
10033 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10034 -ansi -Wall -gall).
10035 * data/yacc.c (union yyalloc): Likewise.
10036 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10037
10038 Switch from 'int' to 'bool' where that makes sense.
10039
10040 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
10041 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,

10055 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
10056 bitset_stats_or_and_cmp): Likewise.
10057 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
10058 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
10059 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
10060 ebitset_xor_cmp): Likewise.
10061 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
10062 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
10063 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
10064 lbitset_xor_cmp): Likewise.
10065 * lib/bbitset.h: Include <stdbool.h>.
10066 (struct bitset_vtable): The following members now return bool, not
10067 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
10068 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
10069 or_and_cmp).
10070 * src/conflicts.c (count_rr_conflicts): Likewise.
10071 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
10072 All uses changed.
10073 * lib/ebitset.c (ebitset_obstack_init): Likewise.
10074 * lib/lbitset.c (lbitset_obstack_init): Likewise.
10075 * src/getargs.c (debug_flag, defines_flag, locations_flag,
10076 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
10077 graph_flag): Likewise.
10078 * src/getargs.h (debug_flag, defines_flag, locations_flag,
10079 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
10080 graph_flag): Likewise.
10081 * src/output.c (error_verbose): Likewise.
10082 * src/output.h (error_verbose): Likewise.
10083 * src/reader.c (start_flag, typed): Likewise.
10084 * src/reader.h (typed): Likewise.
10085 * src/getargs.c (LOCATIONS_OPTION): New constant.
10086 (long_options, getargs): Use it.
10087 * src/lalr.c (build_relations): Use bool, not int.
10088 * src/nullable.c (nullable_compute): Likewise.
10089 * src/print.c (print_reductions): Likewise.
10090 * src/tables.c (action_row, pack_vector): Likewise.
10091 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
10092 * src/output.c (prepare): Use it.
10093 * src/output.c (token_definitions_output,
10094 symbol_destructors_output, symbol_destructors_output): Use string,
10095 not boolean integer, to keep track of whether to output separator.
10096 * src/print_graph.c (print_core): Likewise.
10097 * src/state.c (state_rule_lookaheads_print): Likewise.
10098
10099 * config/install-sh: Sync from automake 1.7.5.
10100
10101 2003-05-14 Paul Eggert <eggert@twinsun.com>
10102
10103 * src/parse-gram.y (rules_or_grammar_declaration): Require a
10104 semicolon after a grammar declaration, in the interest of possible
10105 future changes to the Bison input language.
10106 Do not allow a stray semicolon at the start of the grammar.
10107 (rhses.1): Allow one or more semicolons after any rule, including
10108 just before "|" as required by POSIX.
10109 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
10110 grammar.
10111
10112 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10113
10114 %parse-param support for lalr1.cc.
10115
10116 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
10117 b4_cc_constructor_calls, b4_cc_constructor_call,
10118 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
10119 definitions.
10120 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
10121 parse-param arguments.
10122 (yy::b4_parser_class_name): Declare instance variables to
10123 hold parse-param arguments.
10124 * tests/calc.at: s/value/semantic_value/ because value clashes
10125 with a member of yy::b4_parser_class_name. Adjust C++ code
10126 to handle %parse-param. Enable %parse-param test in C++.
10127
10128 2003-05-12 Paul Eggert <eggert@twinsun.com>
10129
10130 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
10131 English a bit. Fix fclose typo. Change "const char" to "char
10132 const", and use ANSI C rather than K&R for "main". Suggest
10133 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
10134 and suggest yy_switch_to_buffer.
10135
10136 2003-05-05 Paul Eggert <eggert@twinsun.com>
10137
10138 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
10139 C89. This avoids a diagnostic on compilers that define __STDC__
10140 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
10141 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10142
10143 2003-05-03 Paul Eggert <eggert@twinsun.com>
10144
10145 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
10146 Do not overrun array bounds.
10147 This should fix a bug reported today by Olatunji Oluwabukunmi in
10148 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
10149
10150 2003-04-29 Akim Demaille <akim@epita.fr>
10151
10152 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
10153 * src/getargs.c, src/getargs.h: here, as bool, not int.
10154 (nondeterministic_parser): New.
10155 * src/parse-gram.y, src/scan-gram.l: Support
10156 %nondeterministic-parser.
10157 * src/output.c (prepare): Use nondeterministic_parser instead
10158 of glr_parser where appropriate.
10159 * src/tables.c (conflict_row, action_row, save_row)
10160 (token_actions, token_actions, pack_vector): Ditto.
10161
10162 2003-04-29 Akim Demaille <akim@epita.fr>
10163
10164 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
10165
10166 2003-04-29 Akim Demaille <akim@epita.fr>
10167
10168 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
10169 with %pure-parser and %locations to exercise the patch from Yakov
10170 Markovitch below.
10171
10172 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
10173
10174 * data/yacc.c: (b4_lex_param): Corrected for the case where
10175 %lex-param is provided and %pure-parser isn't.
10176
10177 2003-04-27 Paul Eggert <eggert@twinsun.com>
10178
10179 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
10180 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
10181 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
10182 if it is not defined.
10183 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
10184
10185 2003-04-26 Paul Eggert <eggert@twinsun.com>
10186
10187 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
10188 Declare to be of type suitable for the ninf value itself, not of
10189 type suitable for the corresponding table, since the latter might
10190 be unsigned but the ninf value might be negative. This fixes a
10191 bug reported by Alexandre Duret-Lutz in
10192 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
10193
10194 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
10195 invokes it. We shouldn't invoke it twice because it will attempt
10196 to put error.o in the archive twice. This fixes a glitch reported
10197 by Martin Mokrejs in
10198 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10199
10200 2003-04-21 Paul Eggert <eggert@twinsun.com>
10201
10202 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
10203 to gnulib.
10204
10205 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
10206
10207 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
10208 Fix obvious typo that results in uncompilable GLR parsers
10209 when both %pure-parser and %locations are used. (trivial change)
10210
10211 2003-04-17 Paul Eggert <eggert@twinsun.com>
10212
10213 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
10214 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
10215 Do not insert the expected token via unput, as this runs afoul
10216 of a POSIX-compatibility bug in flex 2.5.31.
10217 All uses changed to BEGIN the parent state,
10218 since we no longer insert the expected token via unput.
10219 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
10220 that is no longer emitted after the above change.
10221
10222 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
10223 the first one. This change is from Paul Hilfinger, and it fixes
10224 regression reported by Werner Lemberg in
10225 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
10226
10227 (resolve_sr_conflict): Don't invoke state_errs_set
10228 unless one or more tokens have been explicitly made errors.
10229 Otherwise, the above change causes Bison to abort.
10230
10231 * tests/existing.at (GNU pic Grammar): New test case, taken from
10232 Lemberg's email.
10233
10234 2003-03-31 Akim Demaille <akim@epita.fr>
10235
10236 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
10237
10238 2003-03-31 Akim Demaille <akim@epita.fr>
10239
10240 * src/output.c (prepare_symbols): Avoid trailing spaces in the
10241 output.
10242
10243 2003-03-31 Akim Demaille <akim@epita.fr>
10244
10245 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
10246 From Paul Hilfinger.
10247
10248 2003-03-29 Akim Demaille <akim@epita.fr>
10249
10250 * m4/error.m4: Do not put under dynamic conditions some code which
10251 expansion is under static control.
10252
10253 2003-03-29 Akim Demaille <akim@epita.fr>
10254
10255 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
10256
10257 2003-03-29 Akim Demaille <akim@epita.fr>
10258
10259 * doc/bison.texinfo (Strings are Destroyed): New.
10260
10261 2003-03-13 Paul Eggert <eggert@twinsun.com>
10262
10263 * .cvsignore: Add configure.lineno.
10264 * src/.cvsignore: Add yacc.
10265 * tests/.cvsignore: Add testsuite.log.
10266 * doc/fdl.texi: Sync with latest FSF version.
10267
10268 2003-03-12 Paul Eggert <eggert@twinsun.com>
10269
10270 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10271 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10272 cursor, instead of leaving it undefined. This fixes a bug
10273 reported by Tim Van Holder in
10274 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
10275 * tests/input.at (Torturing the Scanner): Test the scanner on
10276 an empty input file, which was Tim Van Holder's test case.
10277
10278 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
10279 <sys/resource.h> can be included, include sys/time.h and
10280 sys/times.h first, if available. This works around the SunOS
10281 4.1.4 porting bug reported by Bruce Becker in
10282 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
10283
10284 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
10285 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
10286 AC_HEADER_SYS_WAIT.
10287
10288 Merge changes from gnulib. This was prompted because the CVS
10289 snapshot didn't build on Solaris 7 due to strnlen problems.
10290
10291 These changes need to be merged back into gnulib:
10292 * lib/hash.c: Include <stdbool.h> unconditionally.
10293 * m4/onceonly.m4 (m4_quote): New macro.
10294 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
10295 Quote AC_FOREACH variable-expansions properly.
10296 The 2003-01-03 obstack.h change also needs merging.
10297 {end of changes requiring merging}
10298
10299 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
10300 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

10333 2003-03-03 Akim Demaille <akim@epita.fr>
10334
10335 * ro.po: New.
10336

10338
10339 * doc/bison.texinfo (Table of Symbols): Reactivate the
10340 documentation for %lex-param, and %parse-param.
10341
10342 2003-03-02 Akim Demaille <akim@epita.fr>
10343
10344 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
10345 generate verbose error messages.
10346 Use the number of tokens as an upper bound in yytname, as it
10347 cannot be a non terminal.
10348
10349 2003-03-02 Akim Demaille <akim@epita.fr>
10350
10351 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
10352 message.
10353
10354 2003-03-02 Akim Demaille <akim@epita.fr>
10355
10356 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
10357 Use them to exercise yycheck overrun.
10358 Based on Andrew Suffield's grammar.
10359
10360 2003-03-02 Akim Demaille <akim@epita.fr>
10361
10362 Create tests/local.at for Bison generic testing macros.
10363
10364 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
10365 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
10366 This new file.
10367 * tests/calc.at (AT_CHECK_CALC): Adjust.
10368 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
10369 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
10370 * tests/local.at: here.
10371 (AT_COMPILE_CXX): Tags the tests using it as c++.
10372 Ignore the test if CXX is not functional.
10373
10374 2003-03-01 Paul Eggert <eggert@twinsun.com>
10375
10376 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
10377 not loc->end, since loc->end might contain garbage and this leads
10378 to undefined behavior on some platforms.
10379 (id_loc, token_start): Use (IF_LINTed) initial values that do not
10380 depend on *loc, so that the reader doesn't give the the false
10381 impression that *loc is initialized.
10382 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10383 does not survive the return.
10384
10385 2003-03-01 Akim Demaille <akim@epita.fr>
10386
10387 * src/scan-gram.l (code_start): Always initialize it when entering
10388 into yylex, as SC_EPILOGUE is activated *before* the corresponding
10389 yylex invocation. An alternative would be making it static, but
10390 then it starts with the second %%'s beginning, instead of its end.
10391
10392 2003-02-28 Paul Eggert <eggert@twinsun.com>
10393
10394 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
10395 around a UnixWare 7.1.1 porting bug reported by John Hughes in
10396 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
10397
10398 2003-02-26 Paul Eggert <eggert@twinsun.com>
10399
10400 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
10401 Remove Sequent/Pyramid discussion (nobody uses them any more).
10402 Merge VMS and MS-DOS discussion; these ports may well be dead
10403 but let's keep mentioning them for now. Put <> around email
10404 addresses. Add copyright notice.
10405
10406 2003-02-24 Paul Eggert <eggert@twinsun.com>
10407
10408 * data/glr.c (yy_reduce_print): yylineno -> yylno,
10409 to avoid collision with flex use of yylineno.
10410 Problem reported by Bruce Lilly in
10411 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

10417 2003-02-21 Akim Demaille <akim@epita.fr>
10418
10419 * data/lalr1.cc: Use temporary variables instead of casts to
10420 change integer types.
10421 Suggested by Paul Eggert.
10422
10423 2003-02-21 Akim Demaille <akim@epita.fr>
10424
10425 * doc/bison.texinfo: Use "location" consistently to refer to @n,
10426 to avoid confusions with lalr1.cc's notion of Position.
10427 Suggested by Paul Eggert.
10428
10429 2003-02-20 Akim Demaille <akim@epita.fr>
10430
10431 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
10432 before initial_columns.
10433 (location.hh): Use consistent variable names when defining the
10434 operator<<.
10435 Use "last" so that we subtract from Positions, not from unsigned.
10436
10437 2003-02-20 Akim Demaille <akim@epita.fr>
10438
10439 * data/lalr1.cc (position.hh): New subfile, including the extended
10440 and Doxygen'ed documentation of class Position.
10441 (location.hh): Use it.

10444
10445 2003-02-20 Akim Demaille <akim@epita.fr>
10446
10447 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
10448 AT_YACC_IF.
10449 Redefine AT_YYERROR_SEES_LOC_IF using it.
10450 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
10451 not defined.
10452 Don't use the location in yy::Parser::error_ and
10453 yy::Parser::print_ when not %locations.
10454 Activate more lalr1.cc tests.
10455
10456 2003-02-19 Akim Demaille <akim@epita.fr>
10457
10458 * data/lalr1.cc: When displaying a line number, be sure to make it
10459 an int.
10460
10461 2003-02-19 Akim Demaille <akim@epita.fr>
10462
10463 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
10464 Remove, useless.
10465 (YYABORT, YYACCEPT, YYERROR): New.

10471 error recovery, mixing with/without pops and discarding of the
10472 lookahead.
10473 Exercise YYERROR.
10474 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
10475
10476 2003-02-17 Paul Eggert <eggert@twinsun.com>
10477
10478 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
10479 * tests/testsuite.at (AT_COMPILE): Use them.
10480 This fixes the testsuite problem reported by Robert Lentz in
10481 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
10482
10483 2003-02-12 Paul Eggert <eggert@twinsun.com>
10484
10485 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
10486 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
10487 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
10488 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
10489 Check for malloc failure, for consistency with yacc.c.
10490 (yytname_size): Remove, for consistency with yacc.c.
10491
10492 The bug still remains in data/lalr1.cc, as I didn't have time
10493 to fix it there.
10494
10495 2003-02-06 Akim Demaille <akim@epita.fr>
10496
10497 * configure.ac (GXX): Rename as...
10498 (CXX): this, to keep the original Autoconf semantics.
10499 Require 2.57.
10500 * data/lalr1.cc: Fix b4_copyright invocations.
10501 If YYDEBUG is not defined, don't depend upon name_ being defined.
10502 (location.hh): Include string and iostream.
10503 (Position::filename): New member.
10504 (Position::Position ()): New.
10505 (operator<< (Position)): New.
10506 (operator- (Position, int)): New.
10507 (Location::first, Location::last): Rename as...
10508 (Location::begin, Location::end): these, to mock the conventional
10509 iterator names.

10511 * tests/atlocal.in (CXX): New.
10512 * tests/testsuite.at (AT_COMPILE_CXX): New.
10513 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
10514 locations in a more synthetic way.
10515 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
10516 lalr1.cc is used.
10517 Adjust the C locations to match those from Emacs: first column is
10518 column 0.
10519 Change all the expected results.
10520 Conform to the GCS: simplify the locations when applicable.
10521 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
10522 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
10523 these CPP macros with the m4 macros new defined by...
10524 (AT_CHECK_PUSHDEFS): this, i.e.:
10525 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
10526 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
10527 New macros.
10528 (AT_CHECK_POPDEFS): Undefine them.
10529 (AT_CHECK_CALC_LALR1_CC): New.
10530 Use it for the first lalr1.cc test.
10531
10532 2003-02-04 Akim Demaille <akim@epita.fr>
10533
10534 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
10535 Location as is defined.
10536
10537 2003-02-04 Akim Demaille <akim@epita.fr>
10538
10539 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
10540 name_ being defined.
10541
10542 2003-02-03 Paul Eggert <eggert@twinsun.com>
10543
10544 * src/gram.h (start_symbol): Remove unused decl.
10545
10546 Use more-consistent naming conventions for local vars.
10547
10548 * src/derives.c (derives_compute): Change type of local var from
10549 int to rule_number.
10550 * src/gram.c (grammar_rules_partial_print): Likewise.
10551 * src/print.c (print_core): Likewise.
10552 * src/reduce.c (reduce_grammar_tables): Likewise.
10553
10554 * src/gram.c (grammar_dump): Change name of item_number *
10555 local var from r to rp.
10556 * src/nullable.c (nullable_compute): Likewise.
10557
10558 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
10559
10560 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
10561 for symbol or symbol_number var.
10562 * src/reader.c (grammar_start_symbol_set): Likewise.
10563 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
10564 Likewise.
10565 * src/state.c (transitions_to): Likewise.
10566 * src/state.h: Likewise.
10567 * src/tables.c (symbol_number_to_vector_number): Likewise.
10568
10569 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
10570 char * var.
10571
10572 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
10573 var.
10574
10575 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
10576 var.
10577
10578 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
10579 Use str, not s, for char * var. Use ch, not c, for character var.
10580 Use size for size var.
10581
10582 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
10583 char * var.
10584 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for

10590 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
10591 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
10592 param to have same name as that of enum, so that we don't use
10593 "s" to stand for a non-state.
10594
10595 2003-02-02 Akim Demaille <akim@epita.fr>
10596
10597 * src/scan-skel.l: Scan more than one inert character per yylex
10598 invocation.
10599
10600 2003-02-01 Paul Eggert <eggert@twinsun.com>
10601
10602 Version 1.875a.
10603
10604 * po/LINGUAS: Add ms.
10605
10606 2003-01-30 Akim Demaille <akim@epita.fr>
10607
10608 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
10609
10610 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10611
10612 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
10613 of $1.
10614
10615 Changes in response to error report by S. Eken: GLR mode does not
10616 handle negative $ indices or $ indices in embedded rules correctly.
10617 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
10618
10619 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
10620 (b4_rhs_location): Ditto.
10621 (yyfill): New function to copy from stack tree into array
10622 incrementally.
10623 (yyuserAction): Modify to allow incremental move of semantic values
10624 to rhs array when in GLR mode.
10625 Define YYFILL to use in user-defined actions to fill semantic array
10626 as needed.
10627 Remove dummy use of yystack, as there is now a guaranteed use.
10628 (yydoAction): Modify to allow incremental move of semantic values
10629 to rhs array when in GLR mode.
10630 (yyresolveAction): Ditto.
10631 (yyglrShiftDefer): Update comment.
10632 (yyresolveStates): Use X == NULL for pointers, not !X.
10633 (yyglrReduce): Ditto.
10634 (yydoAction): Ditto
10635
10636 * tests/glr-regr1.at: Rename to ...
10637 * tests/glr-regression.at: Add new regression test for the problems
10638 described above (adapted from S. Eken).
10639 Update copyright notice.
10640 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
10641 * tests/Makefile.am: Ditto.
10642
10643 2003-01-28 Paul Eggert <eggert@twinsun.com>
10644
10645 * data/lalr1.cc: Do not use @output_header_name@ unless
10646 b4_defines_flag is set. This fixes two bugs reported by
10647 Tim Van Holder in
10648 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
10649 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
10650
10651 2003-01-21 Paul Eggert <eggert@twinsun.com>
10652
10653 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
10654 we don't need to worry about yyerrlab1 being reported as an
10655 "unused label" by non-GCC C compilers. The downside is that if
10656 locations are used then a couple of statements are duplicated each
10657 time YYERROR is invoked, but the upside is that the warnings
10658 should vanish.
10659 (yyerrlab1): Move code to YERROR.
10660 (yyerrlab2): Remove. Change uses back to yyerrlab1.
10661 This reverts some of the 2002-12-27 change.
10662
10663 2003-01-17 Paul Eggert <eggert@twinsun.com>
10664
10665 * src/output.c (symbol_printers_output): Fix typo that led
10666 to core dump. Problem reported by Antonio Rus in
10667 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
10668
10669 2003-01-13 Akim Demaille <akim@epita.fr>,
10670 Quoc Peyrot <chojin@lrde.epita.fr>,
10671 Robert Anisko <anisko_r@lrde.epita.fr>
10672
10673 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
10674 when the stacks contain one element, as the loop would otherwise
10675 free the last state, and then use the top state (the one we just
10676 popped). This means that the initial elements will not be freed
10677 explicitly, as is the case in yacc.c; it is not a problem, as
10678 these elements have fake values.
10679
10680 2003-01-11 Paul Eggert <eggert@twinsun.com>
10681
10682 * NEWS: %expect-violations are now just warnings, reverting
10683 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
10684 bootstrapping problem reported by Matthias Klose; see
10685 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
10686 * src/conflicts.c (conflicts_print): Likewise.
10687 * tests/conflicts.at (%expect not enough, %expect too much,
10688 %expect with reduce conflicts): Likewise.
10689 * doc/bison.texinfo (Expect Decl): Document this. Also mention
10690 that the warning is enabled if the number of conflicts changes
10691 (not necessarily increases).
10692
10693 * src/getargs.c (version): Update copyright year.
10694
10695 2003-01-09 Akim Demaille <akim@epita.fr>
10696
10697 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
10698
10699 2003-01-08 Paul Eggert <eggert@twinsun.com>
10700
10701 * Makefile.maint (WGETFLAGS):
10702 New macro, containing "-C off" to disable proxy caches.
10703 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
10704 (rel-check): Use $(WGET) instead of wget.
10705
10706 2003-01-06 Paul Eggert <eggert@twinsun.com>
10707
10708 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
10709 the GLR paper of Scott, Johnstone and Hussain.
10710
10711 2003-01-04 Paul Eggert <eggert@twinsun.com>
10712
10713 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
10714 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
10715 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
10716 (EXTRA_LIBRARIES): New var, for liby.a.
10717 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
10718 (EXTRA_SCRIPTS): New var, for yacc.
10719
10720 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
10721 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
10722 Problem reported by Nelson H. F. Beebe.
10723
10724 2003-01-03 Paul Eggert <eggert@twinsun.com>
10725
10726 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
10727 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
10728 when compiling Bison 1.875's `bitset bset = obstack_alloc
10729 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
10730
10731 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
10732 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
10733 grow to a huge size with typical invocation.
10734
10735 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
10736 Use the pattern recommended by Autoconf 2.57, except also protect
10737 against double-definition.
10738 * src/system.h: Likewise.
10739 Portability issues reported by Nelson H. F. Beebe.
10740
10741 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
10742 All uses changed. Provide a definition in both C and C++.
10743 (yytrue, yyfalse): Define even if defined (__cplusplus).
10744
10745 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
10746 Reported by Nelson H. F. Beebe.
10747
10748 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
10749
10750 2003-01-02 Paul Eggert <eggert@twinsun.com>
10751
10752 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
10753 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
10754 Bug reported by Nelson H. F. Beebe.
10755
10756 2003-01-01 Paul Eggert <eggert@twinsun.com>
10757
10758 * Version 1.875.
10759
10760 2002-12-30 Paul Eggert <eggert@twinsun.com>
10761
10762 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
10763 Moved here from...
10764 (<INITIAL>","): Here. This causes stray "," to be treated
10765 more uniformly.
10766
10767 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
10768 last brace in braced code when not in Yacc mode, for compatibility
10769 with Bison 1.35. This resurrects the 2001-12-15 patch to
10770 src/reader.c.
10771
10772 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
10773 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
10774
10775 2002-12-28 Paul Eggert <eggert@twinsun.com>
10776
10777 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
10778 that of SYM's type. This fixes Debian bug 168069, reported by
10779 Thomas Olsson.
10780
10781 2002-12-28 Paul Eggert <eggert@twinsun.com>
10782
10783 Version 1.75f.
10784
10785 Switch back to the Yacc style of conflict reports, undoing some
10786 of the 2002-07-30 change.
10787 * doc/bison.texinfo (Understanding): Use Yacc style for
10788 conflict reports. Also, use new way of locating rules.
10789 * src/conflicts.c (conflict_report):
10790 Renamed from conflict_report_yacc, removing the old
10791 'conflict_report'. Translate the entire conflict report at once,
10792 so that we don't assume that "," has the same interpretation in
10793 all languages.
10794 (conflicts_output): Use Yacc-style conflict report for each state,
10795 instead of our more-complicated style.
10796 (conflicts_print): Use Yacc-style conflict report, except print
10797 the input file name when not emulating Yacc.
10798 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
10799 Conflicted Reduction, %expect not enough, %expect too much,
10800 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
10801 * tests/existing.at (GNU Cim Grammar): Likewise.
10802 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
10803
10804 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
10805 fatal): Don't invoke fflush; it's not needed and it might even be
10806 harmful for stdout, as stdout might not be open.
10807 * src/reduce.c (reduce_print): Likewise.
10808
10809 2002-12-27 Paul Eggert <eggert@twinsun.com>
10810
10811 Fix a bug where error locations were not being recorded correctly.
10812 This problem was originally reported by Paul Hilfinger in
10813 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
10814
10815 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10816 top of the location stack's error locations.
10817 (yyerrlab): Set it. When discarding a token, push its location
10818 onto yylerrsp so that we don't lose track of the error's end.
10819 (yyerrlab1): Now is only the target of YYERROR, so that we can
10820 properly record the location of the action that failed. For GCC
10821 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10822 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10823 (yyerrlab2): New label, which yyerrlab now falls through to.
10824 Compute the error's location by applying YYLLOC_DEFAULT to
10825 the locations of all the symbols that went into the error.
10826 * doc/bison.texinfo (Location Default Action): Mention that
10827 YYLLOC_DEFAULT is also invoked for syntax errors.
10828 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10829 Error locations include the locations of all the tokens that were
10830 discarded, not just the last token.
10831
10832 2002-12-26 Paul Eggert <eggert@twinsun.com>
10833
10834 * src/files.c: Include quote.h.
10835 (compute_output_file_names): Warn if we detect conflicting
10836 outputs to the same file. This should catch the misunderstanding
10837 exemplified by Debian Bug 165349, reported by Bruce Stephens..
10838
10839 * src/conflicts.c (conflicts_print): If the user specifies
10840 "%expect N", report an error if there are any reduce/reduce
10841 conflicts. This is what the manual says should happen.
10842 This fixes Debian bug 130890, reported by Anthony DeRobertis.
10843 * tests/conflicts.at (%expect with reduce conflicts): New test.
10844
10845 Don't use m4_include on relative file names, as it doesn't work as
10846 desired if there happens to be a file with that name under ".".
10847
10848 * m4sugar/version.m4: Remove; it was included but it wasn't used.
10849 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
10850 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
10851 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
10852 * src/output.c (output_skeleton): Use full path names when
10853 specifying a file to include; don't rely on include path, as
10854 it's unreliable when the working file contains a file with
10855 that name.
10856
10857 2002-12-25 Paul Eggert <eggert@twinsun.com>
10858
10859 Remove obsolete references to bison.simple and bison.hairy.
10860 Problem mentioned by Aubin Mahe in
10861 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
10862 * data/glr.c: Comment fix.
10863 * doc/bison.1: Remove references. Also, mention "yacc".
10864
10865 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
10866 with -g option.
10867
10868 * src/parse-gram.y (declaration): Use enum "report_states" rather
10869 than its numeric value 1.
10870
10871 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
10872 opening a new one. This fixes Debian bug 165349, reported by
10873 Bruce Stephens.
10874
10875 2002-12-24 Paul Eggert <eggert@twinsun.com>
10876
10877 Version 1.75e.
10878
10879 * Makefile.maint (cvs-update): Don't assume that the shell
10880 supports $(...), as Solaris sh doesn't.
10881
10882 * src/parse-gram.y (lloc_default): Remove test for empty
10883 nonterminals at the end, since it didn't change the result.
10884
10885 2002-12-24 Paul Eggert <eggert@twinsun.com>
10886
10887 If the user does not define YYSTYPE as a macro, Bison now declares it
10888 using typedef instead of defining it as a macro. POSIX requires this.
10889 For consistency, YYLTYPE is also declared instead of defined.
10890
10891 %union directives can now have a tag before the `{', e.g., the
10892 directive `%union foo {...}' now generates the C code
10893 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10894 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10895 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10896 instead of `yyltype'.
10897
10898 `yystype' and `yyltype' are now obsolescent macros instead of being
10899 typedefs or tags; they are no longer documented and will be
10900 withdrawn in a future release.
10901
10902 * data/glr.c (b4_location_type): Remove.
10903 (YYSTYPE): Renamed from yystype.
10904 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
10905 (struct YYLTYPE): Renamed from struct yyltype.
10906 (YYLTYPE): Renamed from yyltype.
10907 (yyltype, yystype): New (and obsolescent) macros,
10908 for backward compatibility.
10909 * data/yacc.c: Likewise.
10910
10911 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10912 does not specify a union tag. This is for compatibility with
10913 Solaris 9 yacc.
10914
10915 * src/parse-gram.y (add_param): 2nd arg is now char * not char
10916 const *, since it is now modified by stripping surrounding { }.
10917 (current_braced_code): Remove.
10918 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
10919 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
10920 trailing " {...}". Now of type <chars>.
10921 (grammar_declaration): Adjust to bundled tokens.
10922 (code_content): Remove; stripping is now done by add_param.
10923 (print_token_value): Print contents of bundled tokens.
10924 (token_name): New function.
10925
10926 * src/reader.h (braced_code, current_braced_code): Remove.
10927 (token_name): New decl.
10928
10929 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
10930 token_type, not braced_code code_kind. All uses changed.
10931 (SC_PRE_CODE): New state, for scanning after a keyword that
10932 has (or usually has) an immediately-following braced code.
10933 (token_type): New local var, to keep track of which token type
10934 to return when scanning braced code.
10935 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
10936 <INITIAL>"%parse-param", <INITIAL>"%printer",
10937 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
10938 instead of returning a token type immediately.
10939 (<INITIAL>"{"): Set token type.
10940 (<SC_BRACED_CODE>"}"): Use it.
10941 (handle_action_dollar, handle_action_at): Now returns bool
10942 indicating success. Fail if ! current_rule; this prevents a core dump.
10943 (handle_symbol_code_dollar, handle_symbol_code_at):
10944 Remove; merge body into caller.
10945 (handle_dollar, handle_at): Complain in invalid contexts.
10946
10947 * NEWS, doc/bison.texinfo: Document the above.
10948 * NEWS: Fix years and program names in copyright notice.
10949
10950 2002-12-17 Paul Eggert <eggert@twinsun.com>
10951
10952 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
10953 Reporting, Table of Symbols): Omit mentions of %lex-param and
10954 %parse-param from the documentation for now.
10955
10956 2002-12-15 Paul Eggert <eggert@twinsun.com>
10957
10958 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
10959 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10960 lookahead symbol, and which sets yychar in parser actions) and it
10961 disagreed with the Bison documentation. Bug
10962 reported by Andrew Walrond.
10963
10964 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
10965 as the caller now does that.
10966 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
10967 (YYEMPTY): Parenthesize right hand side, since others use it.
10968 (yyparse): Don't assume that our generated code is the only code
10969 that sets yychar.
10970
10971 2002-12-13 Paul Eggert <eggert@twinsun.com>
10972
10973 Version 1.75d.
10974
10975 POSIX requires a "yacc" command.
10976 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
10977 (MOSTLYCLEANFILES): Add yacc.
10978 (yacc): New rule.
10979 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
10980 as an alias for bison y.
10981
10982 * po/LINGUAS: Add da.
10983
10984 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
10985 problem with latest <getopt.h>.
10986 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
10987
10988 * doc/fdl.texi: Upgrade to 1.2.
10989 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
10990 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
10991 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
10992 gnulib.
10993 * config/install-sh: Sync with autotools.
10994
10995 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
10996 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10997 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
10998 locations are requested.
10999 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
11000 locations are requested.
11001
11002 2002-12-12 Paul Eggert <eggert@twinsun.com>
11003
11004 Remove unportable casts and storage allocation tricks.
11005 While we're at it, remove almost all casts, since they
11006 usually aren't needed and are a sign of trouble.
11007
11008 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11009
11010 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11011 the pointer DSET returned by malloc; this isn't portable.
11012 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
11013 Similarly for DERIVES.
11014 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11015 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
11016 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
11017
11018 * src/derives.c (derives_compute): Do not bother invoking
11019 int_of_rule_number, since rule numbers are integers.
11020
11021 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
11022 rather than XMALLOC (char, N).
11023
11024 * src/files.c (filename_split): Rewrite to avoid cast.
11025
11026 * src/gram.h (symbol_number_as_item_number,
11027 item_number_as_symbol_number, rule_number_as_item_number,
11028 item_number_as_rule_number):
11029 Now inline functions rather than macros, to avoid casts.
11030 * src/state.h (state_number_as_int): Likewise.
11031 * src/tables.c (state_number_to_vector_number,
11032 symbol_number_to_vector_number): Likewise.
11033
11034 * src/gram.h (int_of_rule_number): Remove; no longer used.
11035
11036 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
11037 since the resulting storage is always stored into.
11038
11039 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11040 where it's needed.
11041
11042 * src/muscle_tab.c (muscle_m4_output):
11043 Now inline. Return bool, not int.
11044 * src/state.c (state_compare): Likewise.
11045 * src/symtab.c (symbol_check_defined,
11046 symbol_check_alias_consistency, symbol_pack, symbol_translation,
11047 hash_compare_symbol, hash_symbol):
11048 Likewise.
11049 * src/uniqstr.c (uniqstr_print): Likewise.
11050 * src/muscle_tab.c (muscle_m4_output_processor):
11051 New function, to avoid casts.
11052 * src/state.c (state_comparator, stage_hasher): Likewise.
11053 * src/symtab.c (symbol_check_defined_processor,
11054 symbol_check_alias_consistency_processor, symbol_pack_processor,
11055 symbol_translation_processor, hash_symbol_comparator,
11056 hash_symbol_hasher): Likewise.
11057 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11058 * src/muscle_tab.c (muscles_m4_output):
11059 Use new functions instead of casting old functions unportably.
11060 * src/state.c (state_hash_new): Likewise.
11061 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
11062 symbols_token_translations_init):
11063 Likewise.
11064 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11065
11066 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11067 var instead of casting to long, to avoid casts.
11068 (prepare_states): Use MALLOC rather than alloca, so that we don't
11069 have to worry about alloca.
11070 * src/state.c (state_hash_lookup): Likewise.
11071
11072 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11073 local var instead of casting to unsigned char, to avoid casts.
11074
11075 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11076 STATE_ALLOC): Remove.
11077 (transitions_new, errs_new, reductions_new, state_new): Use malloc
11078 rather than calloc, and use offsetof to avoid allocating slightly
11079 too much storage.
11080 (state_new): Initialize all members.
11081
11082 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11083
11084 * src/symtab.c (symbol_free): Remove; unused.
11085 (symbol_get): Remove cast in lhs of assignment.
11086 (symbols_do): Now static. Accept generic arguments, not
11087 hashing-related ones.
11088
11089 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11090 (symbol_processor): Remove.
11091 (symbols_do): Remove decl; now static.
11092
11093 * src/system.h (alloca): Remove; decl no longer needed.
11094 (<stddef.h>): Include, for offsetof.
11095 (<inttypes.>, <stdint.h>): Include if available.
11096 (uintptr_t): New type, if system lacks it.
11097 (CALLOC, MALLOC, REALLOC): New macros.
11098 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
11099 new macros.
11100
11101 * src/tables.c (table_size): Now int, to pacify GCC.
11102 (table_grow, table_ninf_remap): Use signed table size.
11103 (save_row): Don't bother initializing locals when not needed.
11104 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
11105 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
11106

11113
11114 2002-12-09 Paul Eggert <eggert@twinsun.com>
11115
11116 Change identifier spellings to avoid collisions with names
11117 that are reserved by POSIX.
11118
11119 Don't use names ending in _t, since POSIX reserves them.
11120 For consistency, remove _e and _s endings -- they're weren't
11121 needed to remove ambiguity. All uses changed.
11122 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11123 turn was just renamed from struniq_t.
11124 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11125 which in turn was just renamed from struniq_processor_t.
11126 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

11197 value_t_as_yystype -> value_as_yystype.
11198
11199 Don't include <errno.h> in the mainstream code, since it
11200 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
11201 * lib/get-errno.c, lib/get-errno.h: New files.
11202 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
11203 get-errno.c.
11204 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
11205 * src/output.c (output_skeleton): Likewise.
11206 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
11207 instead of errno.
11208 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>\\x[0-9abcdefABCDEF]+):
11209 Likewise.
11210 (handle_action_dollar, handle_action_at): Likewise.
11211 * src/system.h: Do not include <errno.h>.
11212 (TAB_EXT): Renamed from EXT_TAB.
11213 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
11214
11215 Avoid str[a-z]*, since <string.h> reserves that name space.
11216 Change all instances of "struniq" in names to "uniqstr", and
11217 likewise for "STRUNIQ" and "UNIQSTR".
11218 * src/uniqstr.c: Renamed from src/struniq.c.
11219 * src/uniqstr.h: Renamed from src/struniq.h.
11220 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

11230 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
11231 (N_EXPAND): Renamed from N_STRETCH.
11232
11233 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
11234 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
11235 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

11250 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
11251 G_NODE_ALIGNEMENT.
11252
11253
11254 * lib/timevar.c (timevar_report): Renamed from time_report,
11255 for consistency with other names.
11256 * lib/timevar.h (timevar_report): New decl.
11257 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
11258
11259
11260 Sort include-file uses.
11261
11262 Reorder all include files under src to be in the order "system.h".
11263 then the ../lib include files in angle brackets (alphabetized),
11264 then the . include files in double-quotes (alphabetized). Fix
11265 dependency breakages encountered in this process, as follows:
11266 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
11267 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
11268 * src/state.h: Include "symtab.h".
11269
11270 2002-12-08 Paul Eggert <eggert@twinsun.com>
11271
11272 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
11273 since this causes problems when __file__ contains character
11274 sequences like "@" that are treated specially by src/scan-skel.l.
11275 Instead, just use the file's basename. This fixes the bug
11276 reported by Martin Mokrejs in
11277 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
11278
11279 2002-12-06 Paul Eggert <eggert@twinsun.com>
11280
11281 Add support for rules that do not have trailing semicolons, as
11282 POSIX requires. Improve the quality of locations in Bison
11283 diagnostics.
11284
11285 * src/location.c: Include <quotearg.h>.
11286 (empty_location): Now const.
11287 (location_print): New function. Follow the recommendation of the
11288 GNU Coding Standards for locations that span file boundaries.
11289 * src/location.h: Do not include <quotearg.h>; no longer needed.
11290 (boundary): New type.
11291 (location_t): Use it. This allows locations to span file boundaries.
11292 All member uses changed: file -> start.file or end.file (as needed),
11293 first_line -> start.line, first_column -> start.column,
11294 last_line -> end.line, last_column -> end.column.
11295 (equal_boundaries): New function.
11296 (LOCATION_RESET, LOCATION_STEP): Remove.
11297 (LOCATION_PRINT): Remove. All callers changed to use location_print.
11298 (empty_location): Now const.
11299 (location_print): New decl.
11300 * src/parse-gram.y (lloc_default): New function, which handles
11301 empty locations more accurately.
11302 (YYLLOC_DEFAULT): Use it.
11303 (%token COLON): Remove.
11304 (%token ID_COLON): New token.
11305 (rules): Use it.
11306 (declarations, rules): Remove trailing semicolon.
11307 (declaration, rules_or_grammar_declaration):
11308 Allow empty (";") declaration.
11309 (symbol_def): Remove empty actions; no longer needed.
11310 (rules_or_grammar_declaration): Remove trailing semicolon.
11311 (semi_colon.opt): Remove.
11312 * src/reader.h: Include location.h.
11313 (scanner_cursor): New decl.
11314 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
11315 rolling our own.
11316 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
11317 of *loc.
11318 (STEP): Remove. No longer needed, now that adjust_location does
11319 the work. All uses removed.
11320 (scanner_cursor): New var.
11321 (adjust_location): Renamed from extend_location. It now sets
11322 *loc and adjusts the scanner cursor. All uses changed.
11323 Don't bother testing for CR.
11324 (handle_syncline): Remove location arg; now updates scanner cursor.
11325 All callers changed.
11326 (unexpected_end_of_file): Now accepts start boundary of token or
11327 comment, not location. All callers changed. Update scanner cursor,
11328 not the location.
11329 (SC_AFTER_IDENTIFIER): New state.
11330 (context_state): Renamed from c_context. All uses changed.
11331 (id_loc, code_start, token_start): New local vars.
11332 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
11333 processing of Yacc white space and equivalents here.
11334 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11335 instead of returning ID immediately, since we need to search for
11336 a subsequent colon.
11337 (<INITIAL>"'", "\""): Save token_start.
11338 (<INITIAL>"%{", "{", "%%"): Save code_start.
11339 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
11340 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
11341 BEGIN context_state at end, not INITIAL.
11342 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
11343 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
11344 Return correct token start.
11345 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
11346 the start of a character, string or multiline comment is found.
11347 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
11348 Reduction): Adjust reported locations to match the more-precise
11349 results now expected.
11350 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
11351 * tests/reduce.at (Useless Rules, Reduced Automaton,
11352 Underivable Rules): Likewise.
11353 * tests/regression.at (Invalid inputs): No longer `expecting ";"
11354 or "|"' now that so many other tokens are allowed by the new grammar.
11355
11356 * src/complain.h (current_file): Remove duplicate decl;
11357 current_file is now owned by files.h.
11358 * src/complain.c, src/scan-gram.l: Include files.h.
11359
11360 2002-12-06 Paul Eggert <eggert@twinsun.com>
11361
11362 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
11363 promotes to int; it might be unsigned int.
11364 * data/yacc.c (yy_reduce_print): Likewise.
11365
11366 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
11367 be #defined in the prologue, not in the Bison declarations.
11368 This fixes Debian Bug 102878, reported by Shaul Karl.
11369
11370 2002-12-02 Paul Eggert <eggert@twinsun.com>
11371
11372 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
11373 * lib/strtoul.c: New file, from gnulib.
11374 This fixes a porting bug reported by Peter Klein in
11375 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
11376
11377 2002-11-30 Paul Eggert <eggert@twinsun.com>
11378
11379 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
11380 and put only a forward declaration in the prologue. This is for
11381 consistency with the other scanner helper functions.
11382
11383 Type clashes now generate warnings, not errors, since it
11384 appears that POSIX may allow some grammars with type clashes.
11385 * src/reader.c (grammar_current_rule_check): Warn about
11386 type clashes instead of complaining.
11387 * tests/input.at (Type Clashes): Expect warnings, not complaints.
11388
11389 Add Yacc library, since POSIX requires it.
11390 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
11391 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
11392 * lib/main.c, lib/yyerror.c: New files.
11393
11394 gram_error can be static; it need not be extern.
11395 * src/reader.h (gram_error): Remove decl.
11396 * src/parse-gram.y (gram_error): Now static. Add static decl.
11397 (print_token_value): Omit parameter names from forward decl,
11398 for consistency.
11399
11400 2002-11-29 Paul Eggert <eggert@twinsun.com>
11401
11402 * doc/bison.texinfo: Emphasize that yylex and yyerror must
11403 be declared before being used. E.g., one should typically
11404 declare them in the prologue. Use GNU coding style in examples.
11405 Put "const" consistently after the type it modifies. Mention
11406 that C99 supports "inline". Mention that yyerror traditionally
11407 returns "int".
11408
11409 %parse-param and %lex-param now take just one argument, the
11410 declaration; the argument name is deduced from the declaration.
11411
11412 * doc/bison.texinfo (Parser Function, Pure Calling, Error
11413 Reporting, Table of Symbols): Document this.
11414 * src/parse-gram.y (add_param): New function.
11415 (COMMA): Remove.
11416 (declaration): Implement new rule for %parse-param and %lex-param.
11417 * src/scan-gram.l: "," now elicits a warning, rather than being
11418 a token; this is more compatible with byacc.
11419 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
11420
11421 2002-11-27 Paul Eggert <eggert@twinsun.com>
11422
11423 Rename identifiers to avoid real and potential collisions.
11424
11425 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
11426 to avoid collision with lex macro described by Bruce Lilly in
11427 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11428 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11429 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
11430 * src/parse-gram.y (print_token_value): Renamed from yyprint.
11431 All uses changed.
11432 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
11433 The name "yycontrol" violates the name space rules, and this stuff
11434 wasn't being used anyway.
11435 (input): Remove action; this stuff wasn't being used.
11436 (gram_error): Rename local variable yylloc -> loc.
11437 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
11438 (YY_DECL): Don't use "yy" at start of local variables.
11439 All uses changed, e.g., yylloc -> loc.
11440 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
11441 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
11442 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
11443 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
11444
11445 * src/parse-gram.y (gram_error): loc is now const *.
11446 * src/reader.h (gram_error): Likewise.
11447
11448 2002-11-24 Paul Eggert <eggert@twinsun.com>
11449
11450 Version 1.75c.
11451
11452 * tests/actions.at (Actions after errors): Use an output format
11453 more similar to that of the Printers and Destructors test.
11454 Test the position of the ';' token too.
11455 (Printers and Destructors): Likewise.
11456 (Printers and Destructors: %glr-parser): Remove for now, to avoid
11457 unnecessarily alarming people when the test fails.
11458
11459 * data/yacc.c (yyerrlab1): Move this label down, so that the
11460 parser does not discard the lookahead token if the user code
11461 invokes YYERROR. This change is required for POSIX conformance.
11462
11463 * lib/error.c: Sync with gnulib.
11464
11465 2002-11-22 Paul Eggert <eggert@twinsun.com>
11466
11467 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
11468 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
11469 * lib/xmalloc.c: Likewise.
11470
11471 2002-11-20 Paul Eggert <eggert@twinsun.com>
11472
11473 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
11474
11475 2002-11-20 Paul Eggert <eggert@twinsun.com>
11476
11477 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
11478 should use `if (! x) abort ();' rather than `assert (x);', and
11479 anyway it's one less thing to worry about configuring.
11480
11481 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
11482 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
11483 and replace all instances of assert with abort.
11484 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
11485 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
11486
11487 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
11488 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
11489 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
11490 hash_find_entry, hash_rehash, hash_insert): Likewise.
11491 * src/conflicts.c (resolve_sr_conflict): Likewise.

11499 symbol_pack): Likewise.
11500 * src/tables.c (conflict_row, pack_vector): Likewise.
11501 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,

11503 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
11504 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
11505
11506 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
11507 (ARGMATCH_CONSTRAINT): New macro.
11508 (ARGMATCH_ASSERT): Use it.
11509
11510 * src/system.h (verify): New macro.
11511 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
11512 rather than assert.
11513 * src/tables.c (tables_generate): Likewise.
11514
11515 * src/struniq.c (struniq_assert): Now returns void, and aborts
11516 if the assertion is false.

11518 * src/struniq.h: Likewise.
11519
11520 2002-11-18 Paul Eggert <eggert@twinsun.com>
11521
11522 * data/glr.c (yygetLRActions): Replace `yyindex' with
11523 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
11524 This fixes the regression with Sun ONE Studio 7 cc that I reported in
11525 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
11526
11527 2002-11-18 Akim Demaille <akim@epita.fr>
11528
11529 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
11530 space.
11531 From Tim Van Holder.
11532
11533 2002-11-17 Paul Eggert <eggert@twinsun.com>
11534
11535 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
11536 to "SyntaxError" for consistency with my 2002-11-15 change.
11537
11538 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
11539 not define to {}, since this breaks the common use of `YYDPRINTF
11540 ((...));' if a single statement is desired (e.g. before `else').
11541 Work around GCC warnings by surrounding corresponding calls with
11542 {} if needed.
11543 (yyhasResolvedValue): Remove unused function.
11544 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
11545 loop body.
11546 (yyreportSyntaxError): Renamed from yyreportParseError.
11547 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
11548 All uses changed.
11549 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
11550 extern when possible. Remove unused initializations.
11551
11552 2002-11-16 Akim Demaille <akim@epita.fr>
11553
11554 Augment the similarity between GLR and LALR traces.
11555
11556 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
11557 (YY_REDUCE_PRINT): New.
11558 (yyparse): Use them.
11559 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
11560 YYDPRINT here.
11561 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
11562 state reached after the reduction/recovery, since...
11563 (yyparse, yyprocessOneStack): Report the state we are entering in.
11564
11565 2002-11-16 Akim Demaille <akim@epita.fr>
11566
11567 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
11568 Add support for --trace=skeleton.
11569 * src/scan-skel.l: %option debug.
11570 Scan strings of non-@ or \n instead of character by character.
11571 (scan_skel): Handle trace_skeleton.
11572 (QPUTS): New.
11573 (@output_parser_name@, @output_header_name@): ``Restore'' their
11574 support (used to be M4 macros).
11575 * data/yacc.c: Quote larger chunks, a la glr.c.
11576 * data/lalr1.cc: Likewise.
11577 The header guards are no longer available, so use some other
11578 string than `YYLSP_NEEDED'.
11579
11580 2002-11-16 Akim Demaille <akim@epita.fr>
11581
11582 Make the ``Printers and Destructors'' test more verbose, taking
11583 `yacc.c''s behavior as (possibly wrong) reference.
11584
11585 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
11586 instead of fprint on stdout.
11587 Set and report the last_line of the symbols.
11588 Consistently display values and locations.
11589
11590 2002-11-16 Paul Eggert <eggert@twinsun.com>
11591
11592 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
11593
11594 2002-11-15 Paul Eggert <eggert@twinsun.com>
11595
11596 * tests/actions.at (Actions after errors): New test case.
11597
11598 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
11599 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
11600 tests/action.at, tests/calc.at, tests/conflicts.at,
11601 tests/cxx-type.at, tests/regression.at:
11602 "parse error" -> "syntax error" for POSIX compatibility.
11603 "parsing stack overflow..." -> "parser stack overflow" so
11604 that code matches Bison documentation.
11605
11606 2002-11-15 Akim Demaille <akim@epita.fr>
11607
11608 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
11609 take two BRACED_CODE, not two string_content.
11610 Free the scanner's obstack when we are done.
11611 (code_content): New.
11612 * tests/calc.at: Adjust.
11613 * doc/bison.texinfo: Adjust.
11614 Also, make sure to include the `,' for these declarations.
11615
11616 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
11617
11618 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
11619 definition; avoids potential autoreconf problems.
11620
11621 2002-11-15 Akim Demaille <akim@epita.fr>
11622
11623 Always check the value returned by yyparse.
11624
11625 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
11626 returned by yyparse.
11627 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
11628 Adjust calls.
11629 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
11630 returned by yyparse.
11631
11632 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11633
11634 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
11635 on input.at test.
11636
11637 2002-11-14 Paul Eggert <eggert@twinsun.com>
11638
11639 * src/output.c (output_skeleton): Call xfopen instead of
11640 duplicating xfopen's body.
11641
11642 Fix bugs reported by Nelson H. F. Beebe in
11643 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
11644
11645 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
11646 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
11647 Group compiler. Instead, use "$CC -E bar.c". Include the .h
11648 file twice in the grammar, as an extra check.
11649
11650 * tests/input.at (Torturing the Scanner): Surround the
11651 backslash-newline tests with "#if 0", to make it less likely that
11652 we'll run into compiler bugs. Bring back solitary \ inside
11653 comment, but add a closing comment to work around HP C bug. Don't
11654 test backslash-newline in C character constant.
11655
11656 2002-11-14 Akim Demaille <akim@epita.fr>
11657
11658 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
11659 status of the compiler.
11660 Calling `exit 1' is no longer needed.
11661 Reported by Nelson H. F. Beebe.
11662
11663 2002-11-14 Akim Demaille <akim@epita.fr>
11664
11665 * tests/atlocal.in (CPPFLAGS): We have config.h.
11666 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
11667 New.
11668 * tests/actions.at, tests/calc.at, tests/conflicts.at,
11669 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
11670 * tests/regression.at, tests/torture.at: Use them for all the
11671 grammars that are to be compiled.
11672 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
11673 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
11674 * doc/bison.texinfo (GLR Parsers): Document `inline'.
11675
11676 2002-11-14 Akim Demaille <akim@epita.fr>
11677
11678 * doc/bison.texinfo: Various formatting changes (alignments in
11679 samples, additional @group/@end group, GCS in samples.
11680 Use @deffn instead of simple @table to define the directives,
11681 macros, variables etc.
11682
11683 2002-11-13 Paul Eggert <eggert@twinsun.com>
11684
11685 Fix some bugs reported by Albert Chin-A-Young in
11686 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
11687
11688 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
11689 -o c"; the HP C compiler chatters during compilation.
11690 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
11691 * tests/headers.at (export YYLTYPE): Likewise.
11692
11693 * tests/input.at (Torturing the Scanner): Remove lines containing
11694 solitary backslashes, as they tickle a bug in the HP C compiler.
11695
11696 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
11697 comments, since they're not portable. Use GNU coding style.
11698
11699 2002-11-13 Akim Demaille <akim@epita.fr>
11700
11701 * data/yacc.c: Leave bigger chunks of quoted text.
11702 (YYDSYMPRINTF): New.
11703 Use it to report symbol activities.

11707 2002-11-12 Paul Eggert <eggert@twinsun.com>
11708
11709 Version 1.75b.
11710
11711 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
11712 (yyglrReduce): Return yyok, not 0.
11713 This should avoid the enumerated-type warnings reported
11714 by Nelson H. F. Beebe in
11715 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.

11717 * lib/bbitset.h (BITSET_INLINE): Remove.
11718 * lib/bitset.h [! BITSET_INLINE]: Remove.
11719 (bitset_set, bitset_reset, bitset_test): Rename local vars
11720 to avoid shadowing warnings by GCC.
11721
11722 * data/glr.c (inline): Remove #define. It's the user's
11723 responsibility to #define it away, just like 'const'.
11724 This fixes one of the bugs reported by Nelson H. F. Beebe in
11725 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
11726
11727 * Makefile.maint (po-check): Scan .l and .y files instead of the
11728 .c and the .h files that they generate. This fixes the bug
11729 reported by Tim Van Holder in:
11730 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
11731 Look for N_ as well as for _. Try to avoid matching #define for
11732 N_ and _.
11733 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
11734 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
11735 * src/scan-gram.l: Revamp regular expressions so that " and '
11736 do not confuse xgettext.
11737
11738 * src/struniq.h (struniq_new): Do not declare the return type
11739 to be 'const'; this violates the C standard.
11740 * src/struniq.c (struniq_new): Likewise.
11741
11742 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
11743
11744 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
11745 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
11746 linker.
11747
11748 2002-11-12 Akim Demaille <akim@epita.fr>
11749
11750 * Makefile.maint: Sync with Autoconf:

11760 locations.
11761
11762 2002-11-12 Akim Demaille <akim@epita.fr>
11763
11764 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
11765 not yyvalue.
11766
11767 2002-11-12 Akim Demaille <akim@epita.fr>
11768
11769 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.

11773
11774 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
11775 defines it.
11776 * data/glr.c (yystos): New.
11777 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
11778 (YYDSYMPRINT): New.

11780 (yyrecoverParseError): Free verbosely the discarded symbols.
11781 * data/yacc.c (yysymprint): Remove, rather...
11782 (b4_yysymprint_generate): invoke.

11784 Accept pointers as arguments, as opposed to the version from
11785 yacc.c.
11786 (b4_yydestruct_generate): Likewise.
11787 * tests/cations.at (Printers and Destructors): Use Bison directives
11788 instead of CPP macros.
11789 Don't rely on internal details.
11790
11791 2002-11-12 Akim Demaille <akim@epita.fr>
11792
11793 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
11794 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
11795 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
11796 it against YYEMPTY and so forth), work on yytoken (i.e., set
11797 it to YYEMPTY etc.).
11798 (yydestruct): Replace with a b4_yydestruct_generate invocation.
11799 (b4_symbol_actions): Remove.
11800 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
11801 for 0, end-of-input.
11802
11803 2002-11-12 Akim Demaille <akim@epita.fr>
11804
11805 * doc/bison.texinfo (Destructor Decl): New.
11806

11816 the file name.
11817
11818 2002-11-12 Akim Demaille <akim@epita.fr>
11819
11820 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
11821 Restore.
11822 * src/scan-gram.l (last_string): Is global to the file, not to
11823 yylex.
11824 * src/parse-gram.y (input): Don't append the epilogue here,
11825 (epilogue.opt): do it here, and free the scanner's obstack.
11826 * src/reader.c (epilogue_set): Rename as...
11827 (epilogue_augment): this.
11828 * data/c.m4 (b4_epilogue): Defaults to empty.
11829

11886 2002-11-11 Paul Eggert <eggert@twinsun.com>
11887
11888 Revamp to fix many (but not all) of the C- and M4-related quoting
11889 problems. Among other things, this fixes the Bison bug reported
11890 by Jan Hubicka when processing the Bash grammar; see:
11891 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
11892
11893 Use new @ escapes consistently. Represent brackets with @{ and @}
11894 rather than @<:@ and @:>@, since this works a bit better with dumb
11895 editors like vi. Represent @ with @@, since @ is now consistently
11896 an escape. Use @oline@ and @ofile@ rather than __oline__ and
11897 __ofile__, to avoid unexpected expansions. Similarly, use @output
11898 rather than #output.
11899
11900 * data/c.m4 (b4_copyright): Omit file name from comment, since
11901 the file name could contain "*/".
11902 (b4_synclines_flag): Don't quote the 2nd argument; it should already
11903 be quoted. All uses changed.
11904
11905 * data/glr.c: Use new @ escapes consistently.
11906 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
11907 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
11908 Remove, since they couldn't handle arbitrary characters in file
11909 names.
11910 * data/lalr1.cc: Likewise.
11911 * data/yacc.c: Likewise.
11912
11913 * src/files.c (output_infix): Remove; all uses removed.
11914 * src/files.h: Likewise.
11915
11916 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
11917 mishandled funny characters in file names, and anyway it isn't
11918 needed any more.
11919 * data/yacc.c: Likewise.
11920 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
11921
11922 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
11923 * data/yacc.c: Likewise.
11924
11925 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
11926 strings now.
11927 (muscle_init): Quote filename as a C string.
11928 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
11929 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
11930 * src/output.c (escaped_file_name_output): New function.
11931 (prepare_symbols): Quote tokens for M4.
11932 (prepare): Don't insert output_infix, output_prefix,
11933 output_parser_name, output_header_name; this is now down by scan-skel.
11934 Insert skeleton as a C string.
11935
11936 * src/output.c (user_actions_output, symbol_destructors_output,
11937 symbol_printers_output): Quote filenames for C and M4.
11938 * src/reader.c (prologue_augment, epilogue_set): Likewise.
11939
11940 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
11941 escapes other than \\ and \'; this simplifies the code.
11942 (<SC_STRING>): Likewise, for \\ and \".
11943 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
11944 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
11945 Use new escapes @{ and @} for [ and ].
11946
11947 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11948 them with auto vars.
11949 Switch to new escape scheme, where @ is the escape character uniformly.
11950 Abort if a stray escape character is found. Avoid unbounded input
11951 buffer when parsing non-escaped text.
11952
11953 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
11954 __oline__, #output, $@, and @{ do not have unintended meanings.
11955
11956 2002-11-09 Paul Eggert <eggert@twinsun.com>
11957
11958 Fix the test failure due to GCC warnings described in
11959 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
11960 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
11961 evaluate to 0 if it's impossible for NINF to be in the respective
11962 table.
11963 (yygetLRActions, yyrecoverParseError): Use them.
11964
11965 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
11966 counted in the token inserted at end of file. Now takes
11967 location_t *, not location_t, so that the location can be
11968 adjusted. All uses changed.
11969
11970 * tests/regression.at (Invalid inputs): Adjust wording in
11971 diagnostic to match the new behavior.
11972
11973 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
11974 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
11975 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
11976 abort ();'. This reduces the runtime of the "Many lookaheads"
11977 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
11978 GCC 3.2.
11979
11980 2002-11-07 Paul Eggert <eggert@twinsun.com>
11981
11982 * src/parse-gram.y (CHARACTER): Remove unused token.
11983 All uses removed.
11984
11985 * src/scan-gram.l: Remove stack option. We no longer use the
11986 stack, since the stack was never deeper than 1; instead, use the
11987 new auto var c_context to record the stacked value.
11988
11989 Remove nounput option. At an unexpected end of file, we now unput
11990 the minimal input necessary to end cleanly; this simplifies the
11991 code.
11992
11993 Avoid unbounded token sizes where this is easy.
11994
11995 (unexpected_end_of_file): New function.
11996 Use it to systematize the error message on unexpected EOF.
11997 (last-string): Now auto, not static.
11998 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
11999 (scanner_last_string_free): Remove; not used.
12000 (percent_percent_count): Move decl to just before use.
12001 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
12002 not the (never otherwised-used) CHARACTER.
12003
12004 2002-11-07 Akim Demaille <akim@epita.fr>
12005
12006 Let yyerror always receive the msg as last argument, so that
12007 yyerror can be variadic.
12008
12009 * data/yacc.c (b4_yyerror_args): New.
12010 Use it when calling yyerror.
12011 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
12012 Use it when calling yyerror.
12013 * doc/bison.texinfo (Error Reporting): Adjust.
12014 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
12015 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
12016
12017 2002-11-06 Akim Demaille <akim@epita.fr>
12018
12019 #line should have quoted strings.
12020 Ideally, this should be done by m4_quotearg.
12021
12022 * src/scan-skel.l: Include quotearg.h.
12023 Quote __ofile__.
12024 * src/output.c (symbol_printers_output)
12025 (symbol_destructors_output): Quote the file name.
12026
12027 2002-11-06 Akim Demaille <akim@epita.fr>
12028
12029 * tests/regression.at (Invalid inputs): Adjust to the recent
12030 messages.
12031
12032 2002-11-06 Akim Demaille <akim@epita.fr>
12033
12034 Restore --no-lines.
12035 Reported by Jim Kent.
12036
12037 * data/c.m4 (b4_syncline): New.
12038 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
12039 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
12040 * src/output.c (user_actions_output): Likewise.
12041 (prepare): Define 'b4_synclines_flag'.
12042 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
12043
12044 2002-11-06 Akim Demaille <akim@epita.fr>
12045
12046 * src/main.c (main): Free `infile'.
12047 * src/scan-gram.l (handle_syncline): New.
12048 Recognize `#line'.
12049 * src/output.c (user_actions_output, symbol_destructors_output)
12050 (symbol_printers_output): Use the location's file name, not
12051 infile.
12052 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12053
12054 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12055
12056 * src/tables.c (matching_state): Don't allow states to match if
12057 either has GLR conflict entries.
12058
12059 2002-11-05 Paul Eggert <eggert@twinsun.com>
12060
12061 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12062 "integer out of range" rather than "invalid value".
12063 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12064 accordingly.
12065
12066 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12067 Also, remove one static variable in the scanner.
12068
12069 * src/scan-gram.l (braces_level): Now auto, not static.
12070 Initialize to zero if the compiler is being picky.
12071 (INITIAL): Clear braces_level instead of incrementing it.
12072 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
12073 as POSIX 1003.1-2001 requires.
12074 * src/system.h (IF_LINT): New macro, taken from coreutils.
12075 * configure.ac: Define "lint" if --enable-gcc-warnings.
12076
12077 2002-11-05 Akim Demaille <akim@epita.fr>
12078
12079 * src/scan-gram.l: When it starts with `%', complain about the
12080 whole directive, not just that `invalid character: %'.
12081
12082 2002-11-04 Akim Demaille <akim@epita.fr>
12083
12084 * Makefile.maint: Update from Autoconf.
12085 (update, cvs-update, po-update, do-po-update): New.
12086
12087 2002-11-04 Akim Demaille <akim@epita.fr>
12088
12089 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
12090 and yyerror.
12091 Have yyerror `use' its arguments.
12092 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
12093 returns true when location & yacc & pure & parse-param.
12094 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
12095
12096 2002-11-04 Akim Demaille <akim@epita.fr>
12097
12098 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
12099 clashes.
12100 * src/scan-gram.l: Use [\'] instead of ['] to pacify
12101 font-lock-mode.
12102 Use complain_at.
12103 Use quote, not quote_n since LOCATION_PRINT no longer uses the
12104 slot 0.
12105
12106 2002-11-03 Paul Eggert <eggert@twinsun.com>
12107
12108 * src/reader.c (get_merge_function, grammar_current_rule_check):
12109 Use consistent diagnostics for reporting type name clashes.
12110 Quote the types with <>, for consistency with Yacc.
12111 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
12112
12113 2002-11-03 Akim Demaille <akim@epita.fr>
12114
12115 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
12116 New.
12117 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
12118 (b4_parse_param): Remove.
12119 Use b4_identification.
12120 Propagate b4_pure_args where needed to pass them to yyerror.
12121 * data/glr.m4 (b4_parse_param): Remove.
12122 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
12123 (b4_lpure_formals): New.
12124 Use b4_identification.
12125 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
12126 b4_user_formals and b4_user_args.
12127 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
12128 (yyreportAmbiguity): When using a pure parser, also need
12129 the location, and the parse-params.
12130 Adjust callers.
12131 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
12132 When using a pure parser, also need the parse-params.
12133 Adjust callers.
12134 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
12135 (%pure-parser + %parse-param) LALR and GLR parsers.
12136 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
12137 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
12138 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
12139 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

12145 (Error Reporting): Adjust to these new directives.
12146 Document %error-verbose, deprecate YYERROR_VERBOSE.
12147
12148 2002-11-03 Akim Demaille <akim@epita.fr>
12149
12150 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
12151 AT_CHECK_CALC_GLR invocations to use % directives, instead of
12152 command line options.
12153 * tests/cxx-type.at: Formatting changes.
12154
12155 2002-11-03 Paul Eggert <eggert@twinsun.com>
12156
12157 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
12158 to count columns correctly, and to check for invalid inputs.
12159
12160 Use mbsnwidth to count columns correctly. Account for tabs, too.
12161 Include mbswidth.h.
12162 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
12163 (extend_location): New function.
12164 (YY_LINES): Remove.
12165
12166 Handle CRLF in C code rather than in Lex code.
12167 (YY_INPUT): New macro.
12168 (no_cr_read): New function.
12169
12170 Scan UCNs, even though we don't fully handle them yet.
12171 (convert_ucn_to_byte): New function.
12172
12173 Handle backslash-newline correctly in C code.
12174 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
12175 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
12176 all uses changed.
12177 (tag, splice): New EREs. Do not allow NUL or newline in tags.
12178 Use {splice} wherever C allows backslash-newline.
12179 YY_STEP after space, newline, vertical-tab.
12180 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
12181
12182 (letter, id): Don't assume ASCII; e.g., spell out a-z.
12183
12184 ({int}, handle_action_dollar, handle_action_at): Check for integer
12185 overflow.
12186
12187 (YY_STEP): Omit trailing semicolon, so that it's more like C.
12188
12189 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
12190 as well as \000. Check for UCHAR_MAX, not 255.
12191 Allow \x with an arbitrary positive number of digits, as in C.
12192 Check for overflow here.
12193 Allow \? and UCNs, for compatibility with C.
12194
12195 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
12196 with quote slot used by complain_at.
12197
12198 * tests/input.at: Add tests for backslash-newline, m4 quotes
12199 in symbols, long literals, and funny escapes in strings.
12200
12201 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
12202 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
12203 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
12204 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
12205 * m4/mbswidth.m4: New file, from GNU coreutils.
12206
12207 * doc/bison.texinfo (Grammar Outline): Document // comments.
12208 (Symbols): Document that trigraphs have no special meaning in Bison,
12209 nor is backslash-newline allowed.
12210 (Actions): Document that trigraphs have no special meaning.
12211
12212 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
12213 no longer used.
12214
12215 2002-11-02 Paul Eggert <eggert@twinsun.com>
12216
12217 * src/reader.c: Don't include quote.h; not needed.
12218 (get_merge_function): Reword warning to be consistent with
12219 type clash diagnostic in grammar_current_rule_check.
12220
12221 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
12222 bug in trigraph handling.
12223
12224 * src/output.c (prepare_symbols): When printing token names,
12225 escape "[" as "@<:@" and likewise for "]".
12226
12227 * src/system.h (errno): Remove declaration, as we are now
12228 assuming C89 or better, and C89 guarantees errno.
12229
12230 2002-10-30 Paul Eggert <eggert@twinsun.com>
12231
12232 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
12233 Check for close failures.
12234 * src/files.h (xfclose): Return void, not int, since it always
12235 returned zero.
12236 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12237 indicates one.
12238 * src/output.c (output_skeleton): Use xfclose rather than fclose
12239 and ferror. xfclose now checks ferror.
12240
12241 * data/glr.c (YYLEFTMOST_STATE): Remove.
12242 (yyreportTree): Use a stack-based leftmost state. This avoids
12243 our continuing battles with bogus warnings about initializers.
12244
12245 2002-10-30 Akim Demaille <akim@epita.fr>
12246
12247 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
12248 #if.
12249
12250 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12251
12252 * tests/glr-regr1.at: New test for reported regressions.
12253 * tests/testsuite.at: Add glr-regr1.at test.
12254 * tests/Makefile.am: Add glr-regr1.at test.
12255
12256 2002-10-24 Paul Eggert <eggert@twinsun.com>
12257
12258 Version 1.75a.
12259
12260 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
12261 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12262 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12263 Don't assume strdup exists; POSIX says its an XSI extension.
12264 Check for buffer overflow on input.
12265
12266 2002-10-24 Akim Demaille <akim@epita.fr>
12267
12268 * src/output.c (output_skeleton): Don't disable M4sugar comments
12269 too soon: it results in comments being expanded.
12270 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
12271 first output.
12272
12273 2002-10-24 Akim Demaille <akim@epita.fr>
12274
12275 * data/yacc.c (m4_int_type): New.
12276 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
12277 char' as only yacc.c wants K&R portability.
12278 * data/glr.c (yysigned_char): Remove.
12279 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
12280 Reported by Quoc Peyrot.
12281
12282 2002-10-23 Paul Eggert <eggert@twinsun.com>
12283
12284 * src/main.c (main): With --trace=time, report times even if a
12285 non-fatal error occurs. Formerly, the times were reported in some
12286 such cases but not in others.
12287 * src/reader.c (reader): Just return if a complaint has been issued,
12288 instead of exiting, so that 'main' can report times.
12289
12290 2002-10-22 Akim Demaille <akim@epita.fr>
12291
12292 * src/system.h: Include sys/types.
12293 Reported by Bert Deknuydt.
12294
12295 2002-10-23 Paul Eggert <eggert@twinsun.com>
12296
12297 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
12298 Suggested by Art Haas.
12299
12300 2002-10-22 Paul Eggert <eggert@twinsun.com>
12301
12302 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12303 decl; not needed any more.
12304 * src/main.c (main): Use return to exit, undoing yesterday's change.
12305 The last OS that we could find where this wouldn't work is
12306 SunOS 3.5, and that's too old to worry about now.
12307
12308 * data/glr.c (struct yyltype): Define members even when not
12309 doing locations. This is more consistent with yacc.c, and it
12310 works around the following bug reports:
12311 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
12312 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
12313
12314 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
12315 @acronym consistently. Standardize on "Yacc" instead of "YACC",
12316 "Algol" instead of "ALGOL". Give a bit more history about BNF.
12317
12318 2002-10-22 Akim Demaille <akim@epita.fr>
12319
12320 * data/README: New.
12321
12322 2002-10-21 Paul Eggert <eggert@twinsun.com>
12323
12324 Be consistent about 'bool'; the old code used an enum in one
12325 module and an int in another, and this violates the C standard.
12326 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12327 * configure.ac (AC_HEADER_STDBOOL): Add.
12328 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
12329 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
12330 * src/symtab.c (hash_compare_symbol_t): Likewise.
12331 * src/system.h (bool, false, true): Use a definition consistent
12332 with ../lib/hash.c. All uses changed.
12333
12334 * src/complain.c (warning_issued): Renamed from warn_message_count,
12335 so that we needn't worry about integer overflow (!).
12336 Now of type bool. All uses changed.
12337 (complaint_issued): Renamed from complain_message_count; likewise.
12338
12339 * src/main.c (main): Use exit to exit with failure.
12340
12341 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
12342 rather than 1 and 0.
12343 * src/main.c (main): Likewise.
12344 * src/getargs.c (getargs): Likewise.
12345 * src/reader.c (reader): Likewise.
12346
12347 * src/getarg.c (getargs): Remove duplicate code for
12348 "Try `bison --help'".
12349
12350 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
12351 What was that "2" for?
12352
12353 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12354 * src/getargs.c (usage): Likewise.
12355
12356 * src/getargs.c (getargs): When there are too few operands, report
12357 the last one. When there are too many, report the first extra
12358 one. This is how diffutils does it.
12359
12360 2002-10-20 Paul Eggert <eggert@twinsun.com>
12361
12362 Remove K&R vestiges.
12363 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
12364 * src/complain.c (VA_START): Remove. Assume prototypes.
12365 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
12366 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
12367 fatal): Assume prototypes.
12368 * src/complain.h: Assume prototypes.
12369 * src/system.h (PARAMS): Remove.
12370 Include <limits.h> unconditionally, since it's guaranteeed even
12371 for a freestanding C89 compiler.
12372 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
12373 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
12374
12375 2002-10-20 Akim Demaille <akim@epita.fr>
12376
12377 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
12378 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
12379 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
12380 (yyresolveStates, yyresolveAction, yyresolveStack)
12381 (yyprocessOneStack): Use them.
12382 (yy_reduce_print): New.

12385 2002-10-20 Akim Demaille <akim@epita.fr>
12386
12387 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
12388 arguments and output `void'.
12389 (b4_c_function): Rename as...
12390 (b4_c_function_def): this.
12391 (b4_c_function_decl, b4_c_ansi_function_def)
12392 (b4_c_ansi_function_decl): New.
12393 Change the interpretation of the arguments: before `int, foo', now
12394 `int foo, foo'.
12395 * data/yacc.c (yyparse): Prototype and define thanks to these.
12396 Adjust b4_c_function_def uses.
12397 * data/glr.c (yyparse): Likewise, but ANSI only.
12398
12399 2002-10-20 Akim Demaille <akim@epita.fr>
12400
12401 * src/output.c (prepare): Move the definition of `tokens_number',
12402 `nterms_number', `undef_token_number', `user_token_number_max'
12403 to...
12404 (prepare_tokens): Here.
12405 (prepare_tokens): Rename as...
12406 (prepare_symbols): this.
12407 (prepare): Move the definition of `rules_number' to...
12408 (prepare_rules): here.
12409 (prepare): Move the definition of `last', `final_state_number',
12410 `states_number' to...
12411 (prepare_states): here.
12412 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
12413
12414 2002-10-20 Akim Demaille <akim@epita.fr>
12415
12416 * src/tables.h, src/tables.c, src/output.c: Comment changes.
12417
12418 2002-10-20 Akim Demaille <akim@epita.fr>
12419
12420 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
12421 * data/c.m4: here.
12422
12423 2002-10-20 Akim Demaille <akim@epita.fr>
12424
12425 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
12426 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
12427 `pair'.
12428 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
12429 `name' to...
12430 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
12431 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
12432 These.
12433
12434 2002-10-19 Paul Eggert <eggert@twinsun.com>
12435
12436 Do not create a temporary file, as that involves security and
12437 cleanup headaches. Instead, use a pair of pipes.
12438 Derived from a suggestion by Florian Krohm.
12439 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
12440 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
12441 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
12442 (BISON_PREREQ_SUBPIPE): Add.
12443 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
12444 Add subpipe.h, subpipe.c.
12445 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
12446 * po/POTFILES.in: Add lib/subpipe.c.
12447 * src/output.c: Include "subpipe.h".
12448 (m4_invoke): Remove decl.
12449 (scan_skel): New decl.
12450 (output_skeleton): Use pipe rather than temporary file for m4 input.
12451 Check that m4sugar.m4 is readable, to avoid deadlock.
12452 Check for pipe I/O error.
12453 * src/scan-skel.l (readpipe): Remove decl.
12454 (scan_skel): New function, to be used in place of m4_invoke.
12455 Read from stream rather than file.
12456
12457 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
12458 float, as this generates a warning on Solaris 8 + GCC 3.2 with
12459 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
12460 this generates a more-accurate value anyway.
12461
12462 * lib/timevar.c (timervar_accumulate): Rename locals to
12463 avoid confusion with similarly-named more-global.
12464 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
12465
12466 * src/output.c (prepare): Use xstrdup to convert char const *
12467 to char *, to avoid GCC warning.
12468
12469 2002-10-19 Akim Demaille <akim@epita.fr>
12470
12471 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
12472 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
12473 Use them to have `calc.y' ready for %pure-parser.
12474 * data/yacc.c (YYLEX): Pass a yylex return type to
12475 b4_c_function_call.
12476
12477 2002-10-19 Akim Demaille <akim@epita.fr>
12478
12479 Prototype support of %lex-param and %parse-param.
12480
12481 * src/parse-gram.y: Add the definition of the %lex-param and
12482 %parse-param tokens, plus their rules.
12483 Drop the `_' version of %glr-parser.
12484 Add the "," token.
12485 * src/scan-gram.l (INITIAL): Scan them.
12486 * src/muscle_tab.c: Comment changes.
12487 (muscle_insert, muscle_find): Rename `pair' as `probe'.
12488 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
12489 (muscle_entry_s): The `value' member is no longer const.
12490 Adjust all dependencies.
12491 * src/muscle_tab.c (muscle_init): Adjust: use
12492 MUSCLE_INSERT_STRING.
12493 Initialize the obstack earlier.
12494 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
12495 (muscle_pair_list_grow): New.
12496 * data/c.m4 (b4_c_function_call, b4_c_args): New.
12497 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
12498 * tests/calc.at: Use %locations, not --locations.
12499 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
12500
12501 2002-10-19 Akim Demaille <akim@epita.fr>
12502
12503 * src/getargs.c (usage): Take status as argument and exit
12504 accordingly.
12505 Report the traditional `Try ... --help' message when status != 0.
12506 (usage, version): Don't take a FILE * as arg, it is pointless.
12507 (getargs): When there is an incorrect number of arguments, make it
12508 an error, and report it GNUlically thanks to `usage ()'.
12509
12510 2002-10-18 Paul Eggert <eggert@twinsun.com>
12511
12512 * data/glr.c (yyreportParseError): Don't assume that sprintf
12513 yields the length of the printed string, as this is not true
12514 on SunOS 4.1.4. Reported by Peter Klein.
12515
12516 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
12517 * tests/conflicts.at (%nonassoc and eof): Likewise.
12518 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
12519
12520 2002-10-17 Akim Demaille <akim@epita.fr>
12521
12522 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
12523 * src/getargs.c (trace_types, trace_args): Adjust.
12524 * src/reader.c (grammar_current_rule_prec_set)
12525 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
12526 Standardize error messages.
12527 And s/@prec/%prec/!
12528 (reader): Use trace_flag to enable scanner/parser debugging,
12529 instead of an adhoc scheme.
12530 * src/scan-gram.l: Remove trailing debugging code.
12531
12532 2002-10-16 Paul Eggert <eggert@twinsun.com>
12533
12534 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
12535 MUSCLE_TAB_H.
12536
12537 * NEWS: Officially drop support for building Bison with K&R C,
12538 since it didn't work anyway and it's not worth worrying about.
12539 * Makefile.maint (wget_files): Remove ansi2knr.c.
12540 (ansi2knr.c-url_prefix): Remove.
12541 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
12542 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12543 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12544
12545 2002-10-15 Paul Eggert <eggert@twinsun.com>
12546
12547 Stop using the "enum_" trick for K&R-style function definitions;
12548 it confused me, and I was the author! Instead, assume that people
12549 who want to use K&R C compilers (when using these modules in GCC,
12550 perhaps?) will run ansi2knr.
12551
12552 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
12553 All uses of "enum_" changed to "enum ".
12554 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12555 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12556
12557 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

12564 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
12565 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
12566 Use function prototypes; this removes the need for declaring
12567 static functions simply to provide their prototypes.
12568 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,
12569 bitset_andn_or_, bitset_andn_or_cmp_, bitset_bytes, bitset_copy_,

12595 bitsetv_zero, bitsetv_ones, bitsetv_transitive_closure,
12596 bitsetv_dump, debug_bitsetv): Likewise.

12620
12621 2002-10-14 Akim Demaille <akim@epita.fr>
12622
12623 Version 1.75.
12624
12625 2002-10-14 Akim Demaille <akim@epita.fr>
12626
12627 * tests/Makefile.am (maintainer-check-posix): New.
12628
12629 2002-10-14 Akim Demaille <akim@epita.fr>
12630
12631 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
12632 member.
12633
12634 2002-10-14 Akim Demaille <akim@epita.fr>
12635
12636 * src/tables.c (table_ninf_remap): base -> tab.
12637 Reported by Matt Rosing.
12638
12639 2002-10-14 Paul Eggert <eggert@twinsun.com>
12640
12641 * tests/action.at, tests/calc.at, tests/conflicts.at,
12642 tests/cxx-type.at, tests/headers.at, tests/input.at,
12643 tests/regression.at, tests/synclines.at, tests/torture.at:
12644 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
12645 so that the tests still work even if POSIXLY_CORRECT is set.
12646 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
12647
12648 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
12649 for portability to K&R hosts. Fix typo: signed char is guaranteed
12650 only to 127, not to 128.
12651 * data/glr.c (yysigned_char): New type.
12652 * data/yacc.c (yysigned_char): Likewise.
12653 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
12654
12655 2002-10-13 Paul Eggert <eggert@twinsun.com>
12656
12657 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
12658 true due to limited range of data type" warning from GCC.
12659
12660 * data/c.m4 (b4_token_defines): Protect against double-inclusion
12661 by wrapping enum yytokentype's definition inside #ifndef
12662 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
12663
12664 2002-10-13 Akim Demaille <akim@epita.fr>
12665
12666 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
12667 Un yy- yyrhs to avoid the name clash with the global YYRHS.

12669 2002-10-13 Akim Demaille <akim@epita.fr>
12670
12671 * Makefile.maint: Update from Autoconf 2.54.
12672 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
12673
12674 2002-10-13 Akim Demaille <akim@epita.fr>
12675
12676 * src/print.c (print_state): Separate the list of solved conflicts
12677 from the other items.

12679
12680 2002-10-13 Akim Demaille <akim@epita.fr>
12681
12682 Let nondeterministic skeletons be usable with deterministic
12683 tables.
12684
12685 With the patch, GAWK compiled by GCC without -O2 passes its test
12686 suite using a GLR parser driven by LALR tables. It fails with -O2
12687 because `struct stat' gives two different answers on my machine:
12688 88 (definition of an auto var) and later 96 (memset on this var).
12689 Hence the stack is badly corrumpted. The headers inclusion is to
12690 blame: if I move the awk.h inclusion before GLR's system header
12691 inclusion, the two struct stat have the same size.
12692
12693 * src/tables.c (pack_table): Always create conflict_table.
12694 (token_actions): Always create conflict_list.
12695 * data/glr.c (YYFLAG): Remove, unused.
12696
12697 2002-10-13 Akim Demaille <akim@epita.fr>
12698
12699 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
12700 (O0FLAGS): New.
12701 (VALGRIND, GXX): New.
12702 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
12703 * tests/bison.in: Run $PREBISON a pre-command.
12704 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
12705 (maintainer-check-g++): New.
12706 * Makefile.am (maintainer-check): New.
12707
12708 2002-10-13 Akim Demaille <akim@epita.fr>
12709
12710 * data/glr.c: Formatting changes.
12711 Tweak some trace messages to match yacc.c's.
12712
12713 2002-10-13 Akim Demaille <akim@epita.fr>
12714
12715 GLR parsers sometimes raise parse errors instead of performing the
12716 default reduction.
12717 Reported by Charles-Henry de Boysson.
12718
12719 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
12720 check the length of the traces when %glr.
12721 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
12722 GLR's traces.
12723 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
12724 Test GLR parsers.
12725 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
12726 (yyltype): Remove the yy prefix from the member names.
12727 (yytable): Complete its comment.
12728 (yygetLRActions): Map error action number from YYTABLE from
12729 YYTABLE_NINF to 0.
12730 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
12731 (which was a bug: it should have been YYTABEL_NINF, and yet it was
12732 not satisfying as we could compare an YYACTION computed from
12733 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
12734 only value for error actions.
12735 (yyreportParseError): In verbose parse error messages, don't issue
12736 `error' in the list of expected tokens.
12737 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
12738 next action to perform to match glr.c's decoding.
12739 (yytable): Complete its comment.
12740
12741 2002-10-13 Paul Eggert <eggert@twinsun.com>
12742
12743 Fix problem reported by Henrik Grubbstroem in
12744 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
12745 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12746 because the Bison parser reads the second action before reducing
12747 the first one.
12748 * src/scan-gram.l (rule_length): New static var.
12749 Use it to keep track of the rule length in the scanner, since
12750 we can't expect the parser to be in lock-step sync with the scanner.
12751 (handle_action_dollar, handle_action_at): Use this var.
12752 * tests/actions.at (Exotic Dollars): Test for the problem.
12753
12754 2002-10-12 Paul Eggert <eggert@twinsun.com>
12755
12756 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
12757 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
12758 Include <sys/time.h> when checking for clock_t and struct tms.
12759 Use same include order as source.
12760 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
12761 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
12762
12763 * lib/timevar.c: Update copyright date and clarify comments.
12764 (get_time) [IN_GCC]: Keep the GCC version for reference.
12765
12766 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
12767 GCC version as of today, then merge Bison's changes.
12768 Change "GCC" to "Bison" in copyright notice. timevar.def's
12769 author is Akim, so change that too.
12770
12771 * src/reader.c (grammar_current_rule_check):
12772 Don't worry about the default action if $$ is untyped.
12773 Prevents bogus warnings reported by Jim Gifford in
12774 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
12775
12776 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
12777 * data/glr.c, data/lalr1.cc, data/yacc.c:
12778 Output token definitions before the first part of user declarations.
12779 Fixes compatibility problem reported by Jim Gifford for kbd in
12780 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
12781
12782 2002-10-11 Paul Eggert <eggert@twinsun.com>
12783
12784 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
12785 (yyparse): here. This undoes some of the 2002-07-25 change.
12786 Compatibility problem reported by Ralf S. Engelschall with
12787 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
12788
12789 2002-10-11 Akim Demaille <akim@epita.fr>
12790
12791 * tests/regression.at Characters Escapes): New.
12792 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
12793 characters.
12794 Reported by Jan Nieuwenhuizen.

12800 2002-10-10 Paul Eggert <eggert@twinsun.com>
12801
12802 Portability fixes for bitsets; this also avoids several GCC
12803 warnings.
12804
12805 * lib/abitset.c: Include <stddef.h>, for offsetof.
12806 * lib/lbitset.c: Likewise.
12807
12808 * lib/abitset.c (abitset_bytes): Return a size that is aligned
12809 properly for vectors of objects. Do not assume that adding a
12810 header size to a multiple of a word size yields a value that is
12811 properly aligned for the whole union.
12812 * lib/bitsetv.c (bitsetv_alloc): Likewise.
12813
12814 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
12815 unique names for structures.
12816 * lib/ebitset.c (ebitset_bytes): Likewise.
12817 * lib/lbitset.c (lbitset_bytes): Likewise.
12818
12819 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
12820 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
12821 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
12822 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
12823 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
12824 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
12825 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
12826 to improve the type-checking that GCC can do.
12827 * lib/bitset.c (bitset_op4_cmp): Likewise.
12828 * lib/bitset_stats.c (bitset_stats_count,
12829 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
12830 bitset_stats_copy, bitset_stats_disjoint_p,
12831 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
12832 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
12833 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
12834 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
12835 bitset_stats_and_or_cmp, bitset_stats_andn_or,
12836 bitset_stats_andn_or_cmp, bitset_stats_or_and,
12837 bitset_stats_or_and_cmp): Likewise.
12838 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
12839 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
12840 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
12841 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
12842
12843 * lib/abitset.h: Include bitset.h, not bbitset.h.
12844 * lib/ebitset.h: Likewise.
12845 * lib/lbitset.h: Likewise.
12846
12847 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
12848 All instances of parameters of type enum bitset_opts are now of
12849 type enum_bitset_opts, to conform to the C Standard, and similarly
12850 for enum_bitset_type.
12851 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12852 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12853
12854 Do not use "struct bitset_struct" to mean different things in
12855 different modules. Not only is this confusing, it violates
12856 the C Standard, which requires that structure types in different
12857 modules must be compatible if one is to be passed to the other.
12858 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
12859 All instances of "struct bitset_struct *" replaced with "bitset".
12860 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
12861 (union bitset_union, struct abitset_struct, struct ebitset_struct,
12862 struct lbitset_struct, struct bitset_stats_struct): New types.
12863 All uses of struct bitset_struct changed to union bitset_union,
12864 etc.
12865 * lib/abitset.c (struct abitset_struct, abitset,
12866 struct bitset_struct): Remove.
12867 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
12868 struct bitset_struct): Remove.
12869 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
12870 bitset_struct): Remove.
12871 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
12872 Likewise.
12873
12874 Do not call a function of type T using a call that assumes the
12875 function is of a different type U. Standard C requires that a
12876 function must be called with a type that is compatible with its
12877 definition.
12878 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12879 New decls.
12880 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12881 New functions.
12882 * lib/ebitset.c (PFV): Remove.
12883 * lib/lbitset.c (PFV): Likewise.
12884 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
12885 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
12886 decls.
12887 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
12888 (ebitset_vtable): Use them.
12889 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
12890 lbitset_xor): New functions.
12891 (lbitset_vtable): Use them.
12892
12893 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
12894 Declare.
12895
12896 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
12897 GCC warning.
12898 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
12899 Use offsetof, for simplicity.
12900
12901 2002-10-06 Paul Eggert <eggert@twinsun.com>
12902
12903 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
12904 the same width as int. This reapplies a hunk of the 2002-08-12 patch
12905 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
12906 which was inadvertently undone by the 2002-09-30 patch.
12907 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
12908 the same width as int.
12909
12910 2002-10-04 Paul Eggert <eggert@twinsun.com>
12911
12912 Version 1.50.
12913
12914 * configure.ac (AC_INIT), NEWS: Increment version number.
12915
12916 * doc/bison.texinfo: Minor spelling, grammar, and white space
12917 fixes.
12918 (Symbols): Mention that any negative value returned from yylex
12919 signifies end-of-input. Warn about negative chars. Mention
12920 the portable Standard C character set.
12921
12922 The GNU coding standard says CFLAGS and YFLAGS are reserved
12923 for the installer to set.
12924 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
12925 * src/Makefile.am (AM_CFLAGS): Likewise.
12926 (AM_YFLAGS): Renamed from YFLAGS.
12927
12928 Fix some MAX and MIN problems.
12929 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
12930 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
12931 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
12932 * src/reader.c (reader): Use it.
12933
12934 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
12935 POSIX 1003.1-2001 has removed fgrep.
12936
12937 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
12938
12939 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
12940 interpreted as signed.
12941 * lib/ebitset.c (ebitset_list): Fix bug.
12942
12943 2002-10-01 Paul Eggert <eggert@twinsun.com>
12944
12945 More fixes for 64-bit hosts and large bitsets.

12948 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
12949 Use bitset_bindex, not int or unsigned int or size_t, to count bits.
12950 * lib/bbitset.h (struct bitset_vtable.size, struct bitset_vtable.count,
12951 struct bitset_vtable.list, struct bitset_vtable.list_reverse,

12968 Likewise.
12969
12970 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
12971 Use size_t, not unsigned int, to count bytes.
12972 * lib/abitset.h (abitset_bytes): Likewise.
12973 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):

12988 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
12989 abitset_or_and, abitset_or_and_cmp):
12990 Use bitset_windex instead of unsigned int.
12991 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
12992 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
12993 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,

13007 BITSET_SIZE_MAX): New macros.
13008 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
13009 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
13010 to BITSET_WINDEX_MAX.
13011
13012 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
13013 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

13017 when computing sizes.
13018 * lib/ebitset.c (ebitset_elts_grow): Likewise.

13113

13130 * data/yacc.c: Guard the declaration of yytoknum also with
13131 `#ifdef YYPRINT', so it is declared only when used.

13133 2002-09-04 Akim Demaille <akim@epita.fr>
13134
13135 * configure.in: Rename as...

13163 (yyreportParseError): Use size_t for yysize.
13164 (yy_yypstack): No longer nested inside yypstates, as nested
13165 functions are not portable. Do not assume size_t is the
13166 same width as int.
13167 (yypstates): Do not assume that ptrdiff_t is the same width
13168 as int, and similarly for yyposn and YYINDEX.
13169
13170 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
13171
13172 * lib/Makefile.am (INCLUDES): Do not include from the intl
13173 directory, which has been removed.
13174 * src/Makefile.am (INCLUDES): Likewise.

13206 * lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
13207 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
13208
13209 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
13210 PROTOTYPES to check for prototypes, and "defined __STDC__" to
13211 check for void *.
13212
13213 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
13214 size_t; the old version tried to do this but casted improperly.
13215 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
13216 (bitset_test): Now returns int, not unsigned long.
13217

13219 (_): New macro.
13220 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
13221 name locals "index", as it generates unnecessary warnings on some
13222 hosts that have an "index" function.

13225 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

13246 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
13247 lib/timevar.c.
13248 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
13249 manual recommends.
13250 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
13251
13252 * src/complain.c (strerror_r): Remove decl; not needed.
13253 (strerror): Use same pattern as ../lib/error.c.
13254
13255 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
13256
13257 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
13258
13259 * src/main.c (main): Cast result of bindtextdomain and textdomain
13260 to void, to avoid a GCC warning when --disable-nls is in effect.
13261
13262 * src/scan-gram.l: Use strings rather than escapes when possible,
13263 to minimize the number of warnings from xgettext.
13264 (handle_action_dollar, handle_action_at): Don't use isdigit,
13265 as it mishandles negative chars and it may not work as expected
13266 outside the C locale.
13267
13268 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
13269 this is a GCC extension and is not portable to other compilers.
13270
13271 * src/system.h (alloca): Use same pattern as ../lib/error.c.
13272 Do not include <ctype.h>; no longer needed.
13273 Do not include <malloc.h>; no longer needed (and generates
13274 warnings on OpenBSD 3.0).
13275
13276 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
13277 it's not portable.
13278
13279 * tests/regression.at: Do not use 'cc -c input.c -o input';
13280 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
13281
13282 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13283 exit status as failure, not just exit status 1. Sun C exits
13284 with status 2 sometimes.
13285
13286 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
13287 Use it for the two large tests.

13290

13299 * src/tables.c (action_row): Move the computation of rules never
13300 reduced to...
13301 (token_actions): here.
13302 * src/main.c (main): Make the parser before making the report, so
13303 that rules never reduced are computed.
13304 Call grammar_rules_never_reduced_report.
13305 * src/print.c (print_results): Report rules never reduced.
13306 * tests/conflicts.at, tests/reduce.at: Adjust.
13307
13308 2002-08-01 Akim Demaille <akim@epita.fr>
13309
13310 Instead of attaching lookaheads and duplicating the rules being
13311 reduced by a state, attach the lookaheads to the reductions.
13312
13313 * src/state.h (state_t): Remove the `lookaheads',
13314 `lookaheads_rule' member.
13315 (reductions_t): Add a `lookaheads' member.
13316 Use a regular array for the `rules'.

13327 (initialize_LA): this.
13328 (lalr_free): Adjust.
13329 * src/main.c (main): Don't free nullable and derives too early: it
13330 is used by --verbose.
13331 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
13332
13333 2002-08-01 Akim Demaille <akim@epita.fr>

13339 Adjust all dependencies.
13340 * src/nullable.c (set_nullable, free_nullable): Rename as...
13341 (nullable_compute, nullable_free): these.
13342 (rule_list_t): Store rule_t *, not rule_number_t.
13343 * src/state.c (state_rule_lookaheads_print): Directly compare rule
13344 pointers, instead of their numbers.
13345 * src/main.c (main): Call nullable_free, and derives_free earlier,
13346 as they were lo longer used.
13347

13349
13350 * lib/timevar.c (get_time): Include children time.

13353 * src/lalr.c (LA, LArule): Static.
13354 * src/lalr.h, src/lalr.c (lalr_free): New.

13357 table_size, not >.

13360 them.
13361 Don't free LA and LArule, main does.

13450 * src/LR0.c (save_reductions): Don't make the final state too
13451 different: save its reduction (accept) instead of having a state
13452 without any action (no shift or goto, no reduce).
13453 Note: the final state is now a ``regular'' state, i.e., the
13454 parsers now contain `reduce 0' as default reduction.
13455 Nevertheless, since they decide to `accept' when yystate =
13456 final_state, they still will not reduce rule 0.

13507 visible here.
13508 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc

14673
14674 Remove `%thong' support as it is undocumented, unused, duplicates
14675 `%token's job, and creates useless e-mail traffic with people who

15119 `%union' has not yet been seen, pass post_prologue_obstack otherwise.
15120
15121 2002-04-23 Paul Eggert <eggert@twinsun.com>
15122
15123 * data/bison.simple: Remove unnecessary commentary and white
15124 space differences from 1_29-branch.
15125 Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE).
15126
15127 (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
15128 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
15129 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
15130 constructors or destructors.
15131
15132 (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.
15133
15134 2002-04-23 Akim Demaille <akim@epita.fr>
15135
15136 * tests/sets.at (AT_EXTRACT_SETS): Don't use 8 char long sed labels.
15137 * tests/synclines.at (AT_TEST_SYNCLINE): Be robust to GCC's
15138 location with columns.
15139 * tests/conflicts.at (%nonassoc and eof): Don't use `error.h'.
15140 All reported by Paul Eggert.
15141
15142 2002-04-22 Akim Demaille <akim@epita.fr>
15143
15144 * src/reduce.c (dump_grammar): Move to...
15145 * src/gram.h, src/gram.c (grammar_dump): here.
15146 Be sure to separate long item numbers.
15147 Don't read the members of a rule's prec if its nil.
15148
15149 2002-04-22 Akim Demaille <akim@epita.fr>
15150
15151 * src/output.c (table_size, table_grow): New.
15152 (MAXTABLE): Remove, replace uses with table_size.
15153 (pack_vector): Instead of dying when the table is too big, grow it.
15154
15155 2002-04-22 Akim Demaille <akim@epita.fr>
15156
15157 * data/bison.simple (yyr1): Its type is that of a token number.
15158 * data/bison.c++ (r1_): Likewise.
15159 * tests/regression.at (Web2c Actions): Adjust.
15160
15161 2002-04-22 Akim Demaille <akim@epita.fr>
15162
15163 * src/reader.c (token_translations_init): 256 is now the default
15164 value for the error token, i.e., it will be assigned another
15165 number if the user assigned 256 to one of her tokens.
15166 (reader): Don't force 256 to error.
15167 * doc/bison.texinfo (Symbols): Adjust.
15168 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
15169 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
15170 etc. instead of 10, 20, 30 (which was used to `jump' over error
15171 (256) and undefined (2)).
15172
15173 2002-04-22 Akim Demaille <akim@epita.fr>
15174
15175 Propagate more token_number_t.
15176
15177 * src/gram.h (token_number_as_item_number)
15178 (item_number_as_token_number): New.
15179 * src/output.c (GENERATE_OUTPUT_TABLE): New.
15180 Use it to create output_item_number_table and
15181 output_token_number_table.
15182 * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c,
15183 * src/lex.c, src/nullable.c, src/output.c, src/print.c,
15184 * src/print_graph.c, src/reader.c, src/reduce.c, src/state.h,
15185 * src/symtab.c, src/symtab.h: Use token_number_t instead of shorts.
15186
15187 2002-04-22 Akim Demaille <akim@epita.fr>
15188
15189 * src/output.h, src/output.c (get_lines_number): Remove.
15190
15191 2002-04-19 Akim Demaille <akim@epita.fr>
15192
15193 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
15194 as Lex/Flex'.
15195 (Debugging): More details about enabling the debugging features.
15196 (Table of Symbols): Describe $$, $n, @$, and @n.
15197 Suggested by Tim Josling.
15198
15199 2002-04-19 Akim Demaille <akim@epita.fr>
15200
15201 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
15202
15203 2002-04-10 Akim Demaille <akim@epita.fr>
15204
15205 * src/system.h: Rely on HAVE_LIMITS_H.
15206 Suggested by Paul Eggert.
15207
15208 2002-04-09 Akim Demaille <akim@epita.fr>
15209
15210 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
15211 full stderr, and strip it according to the bison options, instead
15212 of composing the error message from different bits.
15213 This makes it easier to check for several error messages.
15214 Adjust all the invocations.
15215 Add an invocation exercising the error token.
15216 Add an invocation demonstrating a stupid error message.
15217 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
15218 Adjust the tests.
15219 Error message are for stderr, not stdout.
15220
15221 2002-04-09 Akim Demaille <akim@epita.fr>
15222
15223 * src/gram.h, src/gram.c (error_token_number): Remove, use
15224 errtoken->number.
15225 * src/reader.c (reader): Don't specify the user token number (2)
15226 for $undefined, as it uselessly prevents using it.
15227 * src/gram.h (token_number_t): Move to...
15228 * src/symtab.h: here.
15229 (state_t.number): Is a token_number_t.
15230 * src/print.c, src/reader.c: Use undeftoken->number instead of
15231 hard coded 2.
15232 (Even though this 2 is not the same as above: the number of the
15233 undeftoken remains being 2, it is its user token number which
15234 might not be 2).
15235 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
15236 `user_token_number_max'.
15237 Output `undef_token_number'.
15238 * data/bison.simple, data/bison.c++: Use them.
15239 Be sure to map invalid yylex return values to
15240 `undef_token_number'. This saves us from gratuitous SEGV.
15241
15242 * tests/conflicts.at (Solved SR Conflicts)
15243 (Unresolved SR Conflicts): Adjust.
15244 * tests/regression.at (Web2c Actions): Adjust.

15249 Adding #line.
15250 Remove the duplicate `typedefs'.
15251 (RhsNumberType): Fix the declaration and various other typos.
15252 Use __ofile__.
15253 * data/bison.simple: Use __ofile__.
15254 * src/scan-skel.l: Handle __ofile__.
15255
15256 2002-04-08 Akim Demaille <akim@epita.fr>
15257
15258 * src/gram.h (item_number_t): New, the type of item numbers in
15259 RITEM. Note that it must be able to code symbol numbers as
15260 positive number, and the negation of rule numbers as negative
15261 numbers.
15262 Adjust all dependencies (pretty many).
15263 * src/reduce.c (rule): Remove this `short *' pointer: use
15264 item_number_t.
15265 * src/system.h (MINSHORT, MAXSHORT): Remove.
15266 Include `limits.h'.
15267 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
15268 (shortcpy): Remove.
15269 (MAXTABLE): Move to...
15270 * src/output.c (MAXTABLE): here.
15271 (prepare_rules): Use output_int_table to output rhs.
15272 * data/bison.simple, data/bison.c++: Adjust.
15273 * tests/torture.at (Big triangle): Move the limit from 254 to
15274 500.
15275 * tests/regression.at (Web2c Actions): Ajust.
15276
15277 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
15278 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
15279 passes, but produces negative #line number, once fixed, GCC is
15280 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
15281 C), it passes.
15282 * src/state.h (state_h): Code input lines on ints, not shorts.
15283
15284 2002-04-08 Akim Demaille <akim@epita.fr>
15285
15286 * src/reduce.c (reduce_grammar): First reduce the nonterminals,
15287 and then the grammar.

15296 * src/output.c (output_table_data): Return the longest number.
15297 (prepare_tokens): Output `token_number_max').
15298 * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
15299 New.
15300 Use them to define yy_token_number_type/TokenNumberType.
15301 Use this type for yytranslate.
15302 * tests/torture.at (Big triangle): Push the limit from 124 to
15303 253.
15304 * tests/regression.at (Web2c Actions): Adjust.
15305
15306 2002-04-07 Akim Demaille <akim@epita.fr>
15307
15308 * tests/torture.at (Big triangle): New.

15374 2002-04-07 Akim Demaille <akim@epita.fr>
15375
15376 * src/gram.h (rule_s): prec and precsym are now pointers
15377 to the bucket giving the priority/associativity.
15378 Member `associativity' removed: useless.
15379 * src/reduce.c, src/conflicts.c: Adjust.
15380

15402
15403 2002-04-07 Akim Demaille <akim@epita.fr>

15406 to reorder ritem itself.
15407
15408 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
15409
15410 2002-04-07 Akim Demaille <akim@epita.fr>
15411
15412 Be sure never to walk through RITEMS, but use only data related to
15413 the rules themselves. RITEMS should be banished.
15414
15415 * src/output.c (output_token_translations): Rename as...
15416 (prepare_tokens): this.
15417 In addition to `translate', prepare the muscles `tname' and

15436 new_state.
15437 * src/closure.c (closure): Now that the initial state has its
15438 items properly set, there is no need for a special case when
15439 creating `ruleset'.
15440
15441 As a result, now the rule 0, reducing to $axiom, is visible in the
15442 outputs. Adjust the test suite.
15443

15453 * src/output.c (output_gram): Likewise.
15454
15455 2002-04-07 Akim Demaille <akim@epita.fr>
15456

15458 bucket.
15459 Adjust all dependencies.
15460 * src/reduce.c (nonterminals_reduce): Don't forget to renumber the
15461 `number' of the buckets too.
15462 * src/gram.h: Include `symtab.h'.
15463 (associativity): Move to...
15464 * src/symtab.h: here.
15465 No longer include `gram.h'.
15466
15467 2002-04-07 Akim Demaille <akim@epita.fr>

15474 the end of `rules', and count them out of `nrules'.
15475 (reduce_output, dump_grammar): Adjust.
15476 * src/print.c (print_grammar): It is no longer needed to check for
15477 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

15479
15480 2002-04-07 Akim Demaille <akim@epita.fr>
15481
15482 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
15483 lacking `+ 1' to nrules, Bison reported as useless a token if it
15484 was used solely to set the precedence of the last rule...
15485
15486 2002-04-07 Akim Demaille <akim@epita.fr>
15487
15488 * data/bison.c++, data/bison.simple: Don't output the current file
15489 name in #line, to avoid useless diffs between two identical
15490 outputs under different names.
15491
15492 2002-04-07 Akim Demaille <akim@epita.fr>
15493
15494 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:
15495 Normalize loops to using `< nrules + 1', not `<= nrules'.
15496

15498
15499 * TODO: Update.

15508 * src/closure.c, src/derives.c, src/gram.h, src/lalr.c,
15509 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
15510 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
15511 RHS, instead of being an index in RITEMS.
15512
15513 2002-04-04 Paul Eggert <eggert@twinsun.com>
15514
15515 * doc/bison.texinfo: Update copyright date.
15516 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.
15517 (Symbols): Warn about running Bison in one character set,
15518 but compiling and/or running in an incompatible one.
15519 Warn about character code 256, too.
15520
15521 2002-04-03 Paul Eggert <eggert@twinsun.com>
15522
15523 * src/bison.data (YYSTACK_ALLOC): Depend on whether
15524 YYERROR_VERBOSE is nonzero, not whether it is defined.
15525
15526 Merge changes from bison-1_29-branch.
15527
15528 2002-03-20 Paul Eggert <eggert@twinsun.com>

15780 2002-02-14 Paul Eggert <eggert@twinsun.com>
15781
15782 Remove the support for C++ namespace cleanliness; it was
15783 causing more problems than it was curing, since it didn't work
15784 properly on some nonstandard C++ compilers. This can wait
15785 for a proper C++ parser.
15786
15787 * NEWS: Document this.

15827 2002-02-07 Robert Anisko <robert@lrde.epita.fr>

15830 more consistent when naming methods and variables. Put preprocessor
15831 directives around tables only needed for debugging.
15832
15833 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15834

15875 (token_definitions_output): No longer keeps track of the output
15876 line number, hence remove the second argument.
15877 (guards_output): Check against the guard member of a rule, not the
15878 action member.
15879 Adjust callers.
15880 (output_skeleton): Don't look for the skeleton location, let m4 do
15881 that.
15882 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
15883 file will be used.
15884 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
15885 (prepare): Given that for the time being changesyntax is not
15886 usable in M4, rename the muscles using `-' to `_'.
15887 Define `defines_flag', `output_parser_name' and `output_header_name'.
15888 * src/output.h (actions_output, guards_output)
15889 (token_definitions_output): Adjust prototypes.
15890 * src/scan-skel.l: Instead of scanning the skeletons, it now
15891 processes the output of m4: `__oline__' and `#output'.

15893 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
15894 to date.

15917
15918 * src/bison.simple (YYSIZE_T): Do not define merely because
15919 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

15921
15922 2002-01-27 Akim Demaille <akim@epita.fr>
15923
15924 Fix `%nonassoc and eof'.
15925
15926 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
15927 which were not properly copied! Replace
15928 memcpy (res->errs, src->errs, src->nerrs);
15929 with
15930 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
15931 !!!
15932 * tests/regression.at (%nonassoc and eof): Adjust to newest
15933 Autotest: `.' is not in the PATH.
15934

15957 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
15958 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
15959 into...
15960 (Invalid inputs): Strengthen: exercise parse_percent_token.
15961
15962 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
15963
15964 * src/Makefile.am: Add bison.c++.
15965 * src/bison.c++: New skeleton.
15966
15967 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
15968
15969 * po/it.po: New.
15970
15971 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
15972
15973 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
15974
15975 2002-01-20 Marc Autret <marc@gnu.org>
15976
15977 * src/files.c (compute_output_file_names): Fix
15978
15979 2002-01-20 Marc Autret <marc@gnu.org>
15980
15981 * tests/output.at: New test.
15982 * src/files.c (compute_base_names): Don't map extensions when
15983 the YACC flag is set, use defaults.
15984 Reported by Evgeny Stambulchik.
15985
15986 2002-01-20 Marc Autret <marc@gnu.org>
15987
15988 * src/system.h: Need to define __attribute__ away for non-GCC
15989 compilers as well (i.e., the vendor C compiler).
15990 Suggested by Albert Chin-A-Young.
15991
15992 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
15993
15994 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
15995 canonical definition.
15996 * src/system.h: Use the canonical definition for PARAMS (avoids
15997 a conflict with the macro from lib/hash.h).
15998
15999 2002-01-11 Akim Demaille <akim@epita.fr>
16000
16001 * configure.in: Use AC_FUNC_STRNLEN.
16002 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
16003
16004 2002-01-09 Akim Demaille <akim@epita.fr>
16005
16006 * src/files.c, src/files.h (output_infix): New.
16007 (tab_extension): Remove.
16008 (compute_base_names): Compute the former, drop the latter.
16009 * src/output.c (prepare): Insert the muscles `output-infix', and
16010 `output-suffix'.
16011 * src/parse-skel.y (string, string.1): New.
16012 (section.header): Use it.
16013 (section.yacc): Remove.
16014 (prefix): Remove too.
16015 * src/scan-skel.l: Adjust.
16016 * src/bison.simple, src/bison.hairy: Adjust.
16017
16018 2002-01-09 Akim Demaille <akim@epita.fr>
16019
16020 * configure.in (WERROR_CFLAGS): Compute it.
16021 * src/Makefile.am (CFLAGS): Pass it.
16022 * tests/atlocal.in (CFLAGS): Idem.
16023 * src/files.c: Fix a few warnings.
16024 (get_extension_index): Remove, unused.
16025
16026 2002-01-08 Akim Demaille <akim@epita.fr>
16027
16028 * src/getargs.c (AS_FILE_NAME): New.
16029 (getargs): Use it to convert DOSish file names.
16030 * src/files.c (base_name): Rename as full_base_name to avoid
16031 clashes with `base_name ()'.
16032 (filename_split): New.
16033 (compute_base_names): N-th rewrite, using filename_split.
16034
16035 2002-01-08 Akim Demaille <akim@epita.fr>
16036
16037 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
16038 New, stolen from the Fileutils 4.1.
16039 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
16040 * configure.in: Check for the presence of memrchr, and of its
16041 prototype.
16042
16043 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
16044
16045 * lib/hash.h (__P): Added definition for this macro.
16046 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
16047 BUILT_SOURCES, to ensure they are generated first.
16048 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
16049 %error-verbose to allow bootstrapping with bison 1.30x.
16050
16051 2002-01-06 Akim Demaille <akim@epita.fr>
16052
16053 * src/reader.c (parse_braces): Don't fetch the next char, the
16054 convention is to fetch on entry.
16055 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
16056 'switch' without a following semicolon.
16057 * tests/regression.at (braces parsing): New.
16058
16059 2002-01-06 Akim Demaille <akim@epita.fr>
16060
16061 Bison is dead wrong in its RR conflict reports.
16062
16063 * tests/torture.at (GNU Cim Grammar): New.
16064 * src/conflicts.c (count_rr_conflicts): Fix.
16065
16066 2002-01-06 Akim Demaille <akim@epita.fr>
16067
16068 Creating package.m4 from configure.ac causes too many problems.
16069
16070 * tests/Makefile.am (package.m4): Create it by hand,
16071 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16072
16073 2002-01-06 Akim Demaille <akim@epita.fr>
16074
16075 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16076 skeleton.h.
16077
16078 2002-01-04 Paul Eggert <eggert@twinsun.com>
16079
16080 * doc/bison.texinfo (Debugging):
16081 Remove YYSTDERR; it's no longer defined or used.
16082 Also, s/cstdio.h/cstdio/.
16083
16084 2002-01-03 Akim Demaille <akim@epita.fr>
16085
16086 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16087
16088 2002-01-03 Akim Demaille <akim@epita.fr>
16089
16090 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16091 tracing code to --trace, wait for a better --trace option, with
16092 args.
16093
16094 2002-01-03 Akim Demaille <akim@epita.fr>
16095
16096 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
16097 The ISO C++ standard is extremely clear about it: stderr is
16098 considered a macro, not a regular symbol (see table 94 `Header
16099 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16100 Therefore std:: does not apply to it. It still does with fprintf.
16101 Also, s/cstdio.h/cstdio/.
16102
16103 2002-01-03 Akim Demaille <akim@epita.fr>
16104
16105 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
16106 for non system headers.
16107
16108 2002-01-02 Akim Demaille <akim@epita.fr>
16109
16110 Equip the skeleton chain with location tracking, runtime trace,
16111 pure parser and scanner.
16112
16113 * src/parse-skel.y: Request a pure parser, locations, and prefix
16114 renaming.
16115 (%union): Having several members with the same type does not help
16116 type mismatches, simplify.
16117 (YYPRINT, yyprint): New.
16118 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
16119 (skel_error): this.
16120 Handle locations.
16121 * src/scan-skel.l: Adjust to these changes.
16122 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
16123 (LOCATION_PRINT, skel_control_t): New.
16124
16125 2001-12-30 Akim Demaille <akim@epita.fr>
16126
16127 * src/parse-skel.y: Get rid of the shift/reduce conflict:
16128 replace `gb' with BLANKS.
16129 * src/scan-skel.l: Adjust.
16130
16131 2001-12-30 Akim Demaille <akim@epita.fr>
16132
16133 * src/system.h: We don't need nor want bcopy.
16134 Throw away MS-DOS crap: we don't need getpid.
16135 * configure.in: We don't need strndup. It was even causing
16136 problems: because Flex includes the headers *before* us,
16137 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16138 not visible.
16139 * lib/xstrndup.c: New.
16140 * src/scan-skel.l: Use it.
16141 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
16142 * src/parse-skel.y: Use %directives instead of #defines.
16143
16144 2001-12-30 Akim Demaille <akim@epita.fr>
16145
16146 * src/skeleton.h: New.
16147 * src/output.c (output_parser, output_master_parser): Remove, dead
16148 code.
16149 * src/output.h (get_lines_number, actions_output, guards_output)
16150 (token_definitions_output): Prototype them.
16151 * src/parse-skel.y: Add the license notice.
16152 Include output.h and skeleton.h.
16153 (process_skeleton): Returns void, and takes a single parameter.
16154 * src/scan-skel.l: Add the license notice.
16155 Include skeleton.h.
16156 Don't use %option yylineno: it seems that then Flex imagines
16157 REJECT has been used, and therefore it won't reallocate its
16158 buffers (which makes no other sense to me than a bug). It results
16159 in warnings for `unused: yy_flex_realloc'.
16160
16161 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
16162
16163 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16164 (MUSCLE_INSERT_PREFIX): ...to there.
16165 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16166 (MUSCLE_INSERT_PREFIX): Move from here...
16167
16168 * src/bison.hairy: Add a section directive. Put braces around muscle
16169 names. This parser skeleton is still broken, but Bison should not
16170 choke on a bad muscle 'syntax'.
16171 * src/bison.simple: Add a section directive. Put braces around muscle
16172 names.
16173
16174 * src/files.h (strsuffix, stringappend): Add declarations.
16175 (tab_extension): Add declaration.
16176 (short_base_name): Add declaration.
16177
16178 * src/files.c (strsuffix, stringappend): No longer static. These
16179 functions are used in the skeleton parser.
16180 (tab_extension): New.
16181 (compute_base_names): Use the computations done in this function
16182 to guess if the generated parsers should have '.tab' in their
16183 names.
16184 (short_base_name): No longer static.
16185
16186 * src/output.c (output_skeleton): New.
16187 (output): Disable call to output_master_parser, and give a try to
16188 a new skeleton handling system.
16189 (guards_output, actions_output): No longer static.
16190 (token_definitions_output, get_lines_number): No longer static.
16191
16192 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
16193
16194 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
16195 parse-skel.y.
16196
16197 * src/parse-skel.y: New file.
16198 * src/scan-skel.l: New file.
16199
16200 2001-12-29 Akim Demaille <akim@epita.fr>
16201
16202 %name-prefix is broken.
16203
16204 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
16205 Adjust all dependencies.
16206 * tests/headers.at (export YYLTYPE): Strengthen this test: use
16207 %name-prefix.
16208
16209 Renaming yylval but not yylloc is not consistent. Now we do.
16210
16211 * src/bison.simple: Prefix yylloc if used.
16212 * doc/bison.texinfo (Decl Summary): Document that.
16213
16214 2001-12-29 Akim Demaille <akim@epita.fr>
16215
16216 * doc/bison.texinfo: Promote `%long-directive' over
16217 `%long_directive'.
16218 Remove all references to fixed-output-files, yacc is enough.
16219
16220 2001-12-29 Akim Demaille <akim@epita.fr>
16221
16222 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
16223 user prologue. These are defaults.
16224 * tests/actions.at (Mid-rule actions): Make sure the user can
16225 define YYDEBUG and YYERROR_VERBOSE.
16226
16227 2001-12-29 Akim Demaille <akim@epita.fr>
16228
16229 * src/output.c (header_output): Don't forget to export YYLTYPE and
16230 yylloc.
16231 * tests/headers.at (export YYLTYPE): New, make sure it does.
16232 * tests/regression.at (%union and --defines, Invalid CPP headers):
16233 Move to...
16234 * tests/headers.at: here.
16235
16236 2001-12-29 Akim Demaille <akim@epita.fr>
16237
16238 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
16239
16240 2001-12-29 Akim Demaille <akim@epita.fr>
16241
16242 * tests/actions.at (Mid-rule actions): Output on a single line
16243 instead of several.
16244
16245 2001-12-29 Akim Demaille <akim@epita.fr>
16246
16247 * doc/bison.texinfo: Formatting changes.
16248
16249 2001-12-29 Akim Demaille <akim@epita.fr>
16250
16251 Don't store the token defs in a muscle, just be ready to output it
16252 on command. Now possible via `symbols'. Fixes a memory leak.
16253
16254 * src/output.c (token_definitions_output): New.
16255 (output_parser, header_output): Use it.
16256 * src/reader.c (symbols_save): Remove.
16257
16258 2001-12-29 Akim Demaille <akim@epita.fr>
16259
16260 * src/bison.simple: Do not provide a default for YYSTYPE and
16261 YYLTYPE before the user's prologue. Otherwise it's hardly... a
16262 default.
16263
16264 2001-12-29 Akim Demaille <akim@epita.fr>
16265
16266 Mid-rule actions are simply... ignored!
16267
16268 * src/reader.c (readgram): Be sure to attach mid-rule actions to
16269 the empty-rule associated to the dummy symbol, not to the host
16270 rule.
16271 * tests/actions.at (Mid-rule actions): New.
16272
16273 2001-12-29 Akim Demaille <akim@epita.fr>
16274
16275 Memory leak.
16276
16277 * src/reader.c (reader): Free grammar.
16278
16279 2001-12-29 Akim Demaille <akim@epita.fr>
16280
16281 Memory leak.
16282
16283 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
16284 since it allocates it for each state, although only one is needed.
16285 (allocate_storage): Do it here.
16286
16287 2001-12-29 Akim Demaille <akim@epita.fr>
16288
16289 * src/options.h, src/options.c (create_long_option_table): Rename
16290 as...
16291 (long_option_table_new): this, with a clearer prototype.
16292 (percent_table): Remove, unused,
16293 * src/getargs.c (getargs): Adjust.
16294
16295 2001-12-29 Akim Demaille <akim@epita.fr>
16296
16297 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
16298 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
16299 as states.
16300
16301 2001-12-29 Akim Demaille <akim@epita.fr>
16302
16303 * src/lalr.c (build_relations): Rename `states' as `states1'.
16304 Sorry, I don't understand exactly what it is, no better name...
16305
16306 2001-12-29 Akim Demaille <akim@epita.fr>
16307
16308 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
16309 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
16310 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
16311 as rules.
16312
16313 2001-12-29 Akim Demaille <akim@epita.fr>
16314
16315 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
16316 ago.
16317
16318 2001-12-29 Akim Demaille <akim@epita.fr>
16319
16320 * src/reader.c, src/reader.h (user_toknums): Remove.
16321 Adjust all users to use symbols[i]->user_token_number.
16322
16323 2001-12-29 Akim Demaille <akim@epita.fr>
16324
16325 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
16326 Adjust all users to use symbols[i]->prec or ->assoc.
16327
16328 2001-12-29 Akim Demaille <akim@epita.fr>
16329
16330 * src/reader.c, src/reader.h (tags): Remove.
16331 Adjust all users to use symbols[i]->tag.
16332
16333 2001-12-29 Akim Demaille <akim@epita.fr>
16334
16335 * src/gram.h, src/gram.c (symbols): New, similar to state_table
16336 and rule_table.
16337 * src/reader.c (packsymbols): Fill this table.
16338 Drop sprec.
16339 * src/conflicts.c (resolve_sr_conflict): Adjust.
16340 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
16341 single table.
16342 Use symbols[i]->tag instead of tags[i].
16343
16344 2001-12-29 Akim Demaille <akim@epita.fr>
16345
16346 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
16347 In addition, put a comment in there, to replace...
16348 * tests/regression.at (%union and C comments): Remove.
16349
16350 2001-12-29 Akim Demaille <akim@epita.fr>
16351
16352 * tests/regression.at (Web2c Actions): Blindly move the actual
16353 output as expected output. The contents *seem* right to me, but I
16354 can't pretend reading perfectly parser tables... Nonetheless, all
16355 the other tests pass correctly, the table look OK, even though the
16356 presence of `$axiom' is to be noted: AFAICS it is useless (but
16357 harmless).
16358
16359 2001-12-29 Akim Demaille <akim@epita.fr>
16360
16361 * src/reader.c (readgram): Don't add the rule 0 if there were no
16362 rules read. In other words, add it _after_ having performed
16363 grammar sanity checks.
16364 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
16365
16366 2001-12-29 Akim Demaille <akim@epita.fr>
16367
16368 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
16369 visible, and some states have now a different number.
16370
16371 2001-12-29 Akim Demaille <akim@epita.fr>
16372
16373 * src/reader.c (readgram): Bind the initial rule's lineno to that
16374 of the first rule.
16375 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
16376 (Solved SR Conflicts): Adjust rule 0's line number.
16377
16378 2001-12-29 Akim Demaille <akim@epita.fr>
16379
16380 Fix the `GAWK Grammar' failure.
16381
16382 * src/LR0.c (final_state): Initialize to -1 so that we do compute
16383 the reductions of the first state which was mistakenly confused
16384 with the final state because precisely final_state was initialized
16385 to 0.
16386 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
16387 now noticed by Bison.
16388 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
16389 have a reduction on $default.
16390
16391 2001-12-29 Akim Demaille <akim@epita.fr>
16392
16393 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
16394 rule line numbers.
16395 * src/closure.c (print_closure): Likewise.
16396 * src/derives.c (print_derives): Likewise.
16397 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
16398 now.
16399
16400 2001-12-29 Akim Demaille <akim@epita.fr>
16401
16402 * src/lalr.c (lookaheads_print): New.
16403 (lalr): Call it when --trace-flag.
16404 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
16405 are dumped.
16406
16407 2001-12-29 Akim Demaille <akim@epita.fr>
16408
16409 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
16410 when walking through ritem, even via rule->rhs.
16411 * src/reduce.c (dump_grammar, useful_production, reduce_output)
16412 (useful_production, useless_nonterminals): Likewise.
16413 (reduce_grammar_tables): Likewise, plus update nritems.
16414 * src/nullable.c (set_nullable): Likewise.
16415 * src/lalr.c (build_relations): Likewise.
16416 * tests/sets.at (Nullable): Adjust.
16417 Fortunately, now, the $axiom is no longer nullable.
16418
16419 2001-12-29 Akim Demaille <akim@epita.fr>
16420
16421 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
16422 the 0-sentinel.
16423 * src/gram.c (ritem_longest_rhs): Likewise.
16424 * src/reduce.c (nonterminals_reduce): Likewise.
16425 * src/print_graph.c (print_graph): Likewise.
16426 * src/output.c (output_rule_data): Likewise.

16429 2001-12-29 Akim Demaille <akim@epita.fr>
16430
16431 * src/output.c: Comment changes.
16432
16433 2001-12-27 Paul Eggert <eggert@twinsun.com>
16434
16435 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
16436 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
16437 Sparc, as they were causing more porting problems than the
16438 (minor) performance improvement was worth.
16439
16440 Also, catch up with 1.31's YYSTD.
16441
16442 2001-12-27 Akim Demaille <akim@epita.fr>
16443
16444 * src/output.c (output_gram): Rely on nritems, not the
16445 0-sentinel. See below.
16446 Use -1 as separator, not 0.
16447 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
16448 Rely on -1 as separator in yyrhs, instead of 0.
16449 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
16450 twice `Now at end of input', therefore there are two lines less to
16451 expect.
16452
16453 2001-12-27 Akim Demaille <akim@epita.fr>
16454
16455 * tests/regression.at (Unresolved SR Conflicts):
16456 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
16457 below.
16458
16459 2001-12-27 Akim Demaille <akim@epita.fr>
16460
16461 * src/LR0.c (new_state): Recognize the final state by the fact it
16462 is reached by eoftoken.
16463 (insert_start_shifting_state, insert_eof_shifting_state)
16464 (insert_accepting_state, augment_automaton): Remove, since now
16465 these states are automatically computed from the initial state.
16466 (generate_states): Adjust.
16467 * src/print.c: When reporting a rule number to the user, substract
16468 1, so that the axiom rule is rule 0, and the first user rule is 1.
16469 * src/reduce.c: Likewise.
16470 * src/print_graph.c (print_core): For the time being, just as for
16471 the report, depend upon --trace-flags to dump the full set of
16472 items.
16473 * src/reader.c (readgram): Once the grammar read, insert the rule
16474 0: `$axiom: START-SYMBOL $'.
16475 * tests/set.at: Adjust: rule 0 is now displayed, and since the
16476 number of the states has changed (the final state is no longer
16477 necessarily the last), catch up.
16478
16479 2001-12-27 Akim Demaille <akim@epita.fr>
16480
16481 Try to make the use of the eoftoken valid. Given that its value
16482 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
16483 is used instead of > 0 where appropriate, (ii), depend upon nritems
16484 instead of the 0-sentinel.
16485
16486 * src/gram.h, src/gram.c (nritems): New.
16487 Expected to be duplication of nitems, but for the time being...
16488 * src/reader.c (packgram): Assert nritems and nitems are equal.
16489 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
16490 * src/closure.c (print_closure, print_fderives): Likewise.
16491 * src/gram.c (ritem_print): Likewise.
16492 * src/print.c (print_core, print_grammar): Likewise.
16493 * src/print_graph.c: Likewise.
16494
16495 2001-12-27 Akim Demaille <akim@epita.fr>
16496
16497 * src/main.c (main): If there are complains after grammar
16498 reductions, then output the report anyway if requested, then die.
16499 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
16500 * src/reader.c (eoftoken): New.
16501 (parse_token_decl): If the token being defined has value `0', it
16502 is the eoftoken.
16503 (packsymbols): No longer hack `tags' to insert `$' by hand.
16504 Be sure to preserve the value of the eoftoken.
16505 (reader): Make sure eoftoken is defined.
16506 Initialize nsyms to 0: now eoftoken is created just like the others.
16507 * src/print.c (print_grammar): Don't special case the eof token.
16508 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16509 lie anyway, albeit pleasant.
16510 * tests/calc.at: Exercise error messages with eoftoken.
16511 Change the grammar so that empty input is invalid.
16512 Adjust expectations.
16513 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
16514
16515 2001-12-27 Akim Demaille <akim@epita.fr>
16516
16517 * configure.in: Check the protos of strchr ans strspn.
16518 Replace strchr if needed.
16519 * src/system.h: Provide the protos of strchr, strspn and memchr if
16520 missing.
16521 * lib/strchr.c: New.
16522 * src/reader.c (symbols_save): Use strchr.
16523
16524 2001-12-27 Akim Demaille <akim@epita.fr>
16525
16526 * src/print.c, src/print_graph.c (escape): New.
16527 Use it to quote the TAGS outputs.
16528 * src/print_graph.c (print_state): Now errors are in red, and
16529 reductions in green.
16530 Prefer high to wide: output the state number on a line of its own.
16531
16532 2001-12-27 Akim Demaille <akim@epita.fr>
16533
16534 * src/state.h, src/state.c (reductions_new): New.
16535 * src/LR0.c (set_state_table): Let all the states have a
16536 `reductions', even if reduced to 0.
16537 (save_reductions): Adjust.
16538 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
16539 * src/print.c (print_reductions, print_actions): Adjust.
16540 * src/output.c (action_row): Adjust.
16541
16542 2001-12-27 Akim Demaille <akim@epita.fr>
16543
16544 * src/state.h, src/state.c (errs_new, errs_dup): New.
16545 * src/LR0.c (set_state_table): Let all the states have an errs,
16546 even if reduced to 0.
16547 * src/print.c (print_errs, print_reductions): Adjust.
16548 * src/output.c (output_actions, action_row): Adjust.
16549 * src/conflicts.c (resolve_sr_conflict): Adjust.
16550
16551 2001-12-27 Akim Demaille <akim@epita.fr>
16552
16553 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
16554

16556
16557 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
16558 * src/print.c: here.
16559 (lookaheadset, shiftset): New, used as additional storage by
16560 print_reductions.
16561 (print_results): Adjust.
16562 (print_shifts, print_gotos, print_errs): New, extracted from...
16563 (print_actions): here.
16564 * src/print_graph.c (print_actions): Remove dead code.
16565
16566 2001-12-27 Akim Demaille <akim@epita.fr>
16567
16568 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
16569 `$n' and `@n'.
16570
16571 2001-12-27 Akim Demaille <akim@epita.fr>
16572
16573 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
16574 (build_relations): Adjust.
16575
16576 2001-12-27 Akim Demaille <akim@epita.fr>
16577
16578 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
16579 duplication.
16580
16581 2001-12-27 Akim Demaille <akim@epita.fr>
16582
16583 * src/reader.c (packgram): Catch nitems overflows.
16584
16585 2001-12-27 Akim Demaille <akim@epita.fr>
16586
16587 * src/files.c, src/files.h (guard_obstack): Remove.
16588 * src/output.c (output): Adjust.
16589 * src/reader.c (parse_braces): New, factoring...
16590 (copy_action, copy_guard): these two which are renamed as...
16591 (parse_action, parse_guard): these.
16592 As a voluntary consequence, using braces around guards is now
16593 mandatory.
16594
16595 2001-12-27 Akim Demaille <akim@epita.fr>
16596
16597 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
16598 * src/reader.c (symbol_list): `guard' and `guard_line' are new
16599 members.
16600 (symbol_list_new): Adjust.
16601 (copy_action): action_line is the first line, not the last.
16602 (copy_guard): Just as for actions, store the `action' only, not
16603 the switch/case/break flesh.
16604 Don't parse the user action that might follow the guard, let...
16605 (readgram): do it, i.e., now, there can be an action after a
16606 guard.
16607 In other words the guard is just explicitly optional.
16608 (packgram): Adjust.
16609 * src/output.c (guards_output): New.
16610 (output_parser): Call it when needed.
16611 (output): Also free the guard and attrs obstacks.
16612 * src/files.c, src/files.h (obstack_save): Remove.
16613 (output_files): Remove.
16614 As a result, if one needs the former `.act' file, using an
16615 appropriate skeleton which requires actions and guards is now
16616 required.
16617 * src/main.c (main): Adjust.
16618 * tests/semantic.at: New.
16619 * tests/regression.at: Use `input.y' as input file name.
16620 Avoid 8+3 problems by requiring input.c when the test needs the
16621 parser.
16622
16623 2001-12-27 Akim Demaille <akim@epita.fr>
16624
16625 * src/reader.c (symbol_list_new): Be sure to initialize all the
16626 fields.
16627
16628 2001-12-27 Akim Demaille <akim@epita.fr>
16629
16630 All the hacks using a final pseudo state are now useless.
16631
16632 * src/LR0.c (set_state_table): state_table holds exactly nstates.
16633 * src/lalr.c (nLA): New.
16634 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
16635 instead of lookaheadsp from the pseudo state (nstate + 1).
16636
16637 2001-12-27 Akim Demaille <akim@epita.fr>
16638
16639 * src/output.c (action_row, token_actions): Use a state_t instead
16640 of a integer, and nlookaheads instead of the following state's
16641 lookaheadsp.
16642
16643 2001-12-27 Akim Demaille <akim@epita.fr>
16644
16645 * src/conflicts.c (log_resolution, flush_shift)
16646 (resolve_sr_conflict, set_conflicts, solve_conflicts)
16647 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
16648 (conflicts_print, print_reductions): Use a state_t instead of an
16649 integer when referring to a state.
16650 As much as possible, depend upon nlookaheads, instead of the
16651 `lookaheadsp' member of the following state (since lookaheads of
16652 successive states are successive, the difference between state n + 1
16653 and n served as the number of lookaheads for state n).
16654 * src/lalr.c (add_lookback_edge): Likewise.
16655 * src/print.c (print_core, print_actions, print_state)
16656 (print_results): Likewise.
16657 * src/print_graph.c (print_core, print_actions, print_state)
16658 (print_graph): Likewise.
16659 * src/conflicts.h: Adjust.
16660
16661 2001-12-27 Akim Demaille <akim@epita.fr>
16662
16663 * src/bison.hairy: Formatting/comment changes.
16664 ANSIfy.
16665 Remove `register' indications.
16666 Add plenty of `static'.
16667
16668 2001-12-27 Akim Demaille <akim@epita.fr>
16669
16670 * src/output.c (prepare): Drop the muscle `ntbase' which
16671 duplicates ntokens.
16672 * src/bison.simple: Formatting/comment changes.
16673 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
16674 is an undocumented synonym.
16675
16676 2001-12-22 Akim Demaille <akim@epita.fr>
16677
16678 * src/output.c (output_table_data): Change the prototype to use
16679 `int' for array ranges: some invocations do pass an int, not a
16680 short.
16681 Reported by Wayne Green.
16682
16683 2001-12-22 Akim Demaille <akim@epita.fr>
16684
16685 Some actions of web2c.y are improperly triggered.
16686 Reported by Mike Castle.
16687
16688 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
16689 * tests/regression.at (Web2c): Rename as...
16690 (Web2c Report): this.
16691 (Web2c Actions): New.

16696 Reported by Mike Castle.
16697
16698 * src/conflicts.c (print_reductions): Fix.
16699 * tests/regression.at (Web2c): New.
16700
16701 2001-12-18 Akim Demaille <akim@epita.fr>
16702
16703 Some host fail on `assert (!"foo")', which expands to
16704 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
16705 Reported by Nelson Beebee.
16706
16707 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
16708 `#define it_succeeded 0' and `assert (it_succeeded)'.
16709
16710 2001-12-17 Marc Autret <autret_m@epita.fr>
16711
16712 * src/bison.simple: Don't hard code the skeleton line and filename.
16713 * src/output.c (output_parser): Rename 'line' as 'output_line'.
16714 New line counter 'skeleton_line' (skeleton-line muscle).
16715
16716 2001-12-17 Paul Eggert <eggert@twinsun.com>
16717
16718 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
16719 YYDEBUG must be defined to a nonzero value.
16720
16721 * src/bison.simple (yytname): Do not assume that the user defines
16722 YYDEBUG to a properly parenthesized expression.
16723
16724 2001-12-17 Akim Demaille <akim@epita.fr>
16725
16726 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
16727 nlookaheads is a new member.
16728 Adjust all users.
16729 * src/lalr.h (nlookaheads): Remove this orphan declaration.
16730 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
16731 state.
16732
16733 2001-12-17 Akim Demaille <akim@epita.fr>

16735 * src/files.h, src/files.c (open_files, close_files): Remove.
16736 * src/main.c (main): Don't open/close files, nor invoke lex_free,
16737 let...

16749
16750 2001-12-17 Akim Demaille <akim@epita.fr>
16751
16752 * src/output.c (output_obstack): Be static and rename as...
16753 (format_obstack): this, to avoid any confusion with files.c's
16754 output_obstack.
16755 * src/reader.h (muscle_obstack): Move to...
16756 * src/output.h: here, since it's defined in output.c.
16757
16758 2001-12-17 Akim Demaille <akim@epita.fr>
16759
16760 * src/output.c (action_row, save_column, default_goto)
16761 (sort_actions, matching_state, pack_vector): Better variable
16762 locality.
16763
16764 2001-12-17 Akim Demaille <akim@epita.fr>

16779 there is one less line per action.
16780
16781 2001-12-16 Marc Autret <autret_m@epita.fr>
16782
16783 * src/bison.simple: Remove a useless #line directive.
16784 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
16785 * src/output.c (get_lines_number): New.
16786 (output_parser): Adjust, now takes care about the lines of a
16787 output muscles.
16788 Fix line numbering.

16800
16801 2001-12-15 Akim Demaille <akim@epita.fr>
16802
16803 Make `make distcheck' work.
16804
16805 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
16806 system.h which uses libgettext.h.
16807
16808 2001-12-15 Akim Demaille <akim@epita.fr>
16809
16810 * src/nullable.c (set_nullable): Useless rules must be skipped,
16811 otherwise, since we range over their symbols, we might look at a
16812 nonterminal which no longer ``exists'', i.e., it is not counted in
16813 `nvars', hence we overflow our arrays.
16814
16815 2001-12-15 Akim Demaille <akim@epita.fr>
16816
16817 The header can also be produced directly, without any obstack!
16818 Yahoo!
16819
16820 * src/files.c, src/files.h (defines_obstack): Remove.
16821 (compute_header_macro): Global.
16822 (defines_obstack_save): Remove.
16823 * src/reader.c (parse_union_decl): No longer output to
16824 defines_obstack: its content can be found in the `stype' muscle
16825 anyway.
16826 (output_token_translations): Merge into...
16827 (symbols_output): this.
16828 Rename as...
16829 (symbols_save): this.
16830 (reader): Adjust.
16831 * src/output.c (header_output): New.
16832 (output): Call it.
16833
16834 2001-12-15 Akim Demaille <akim@epita.fr>
16835
16836 * src/reader.c (parse_union_decl): Instead of handling two obstack
16837 simultaneously, use one to define the `stype' muscle, and use the
16838 value of the latter to fill defines_obstack.
16839 (copy_comment): Remove.
16840 (copy_comment2): Work for a single obstack.
16841 Rename as...
16842 (copy_comment): this.
16843
16844 2001-12-15 Akim Demaille <akim@epita.fr>
16845
16846 * src/lex.c, src/lex.h (xgetc): No longer static.
16847 * src/reader.c (parse_union_decl): Revamp.
16848
16849 2001-12-15 Akim Demaille <akim@epita.fr>
16850
16851 Still making progress in separating Bison into (i) input, (ii)
16852 process, (iii) output: now we can directly output the parser file
16853 without using table_obstack at all.
16854
16855 * src/files.c, src/files.h (table_obstack): Bye bye.
16856 (parser_file_name): New.
16857 * src/files.c (compute_output_file_names): Compute it.
16858 * src/output.c (actions_output, output_parser)
16859 (output_master_parser): To a file instead of an obstack.
16860
16861 2001-12-15 Akim Demaille <akim@epita.fr>
16862
16863 Attach actions to rules, instead of pre-outputting them to
16864 actions_obstack.
16865
16866 * src/gram.h (rule_t): action and action_line are new members.
16867 * src/reader.c (symbol_list): Likewise.
16868 (copy_action): Save the actions within the rule.
16869 (packgram): Save them in rule_table.
16870 * src/output.c (actions_output): New.
16871 (output_parser): Use it on `%%actions'.
16872 (output_rule_data): Don't free rule_table.
16873 (output): Do it.
16874 (prepare): Don't save the `action' muscle.
16875 * src/bison.simple: s/%%action/%%actions/.
16876
16877 2001-12-15 Akim Demaille <akim@epita.fr>
16878
16879 * src/reader.c (copy_action): When --yacc, don't append a `;'
16880 to the user action: let it fail if lacking.
16881 Suggested by Arnold Robbins and Tom Tromey.
16882
16883 2001-12-14 Akim Demaille <akim@epita.fr>
16884
16885 * src/lex.c (literalchar): Simply return the char you decoded, non
16886 longer mess around with obstacks and int pointers.
16887 Adjust all callers.
16888
16889 2001-12-14 Akim Demaille <akim@epita.fr>
16890
16891 * src/lex.c (literalchar): Don't escape the special characters,
16892 just decode them, and keep them as char (before, eol was output as
16893 the 2 char string `\n' etc.).
16894 * src/output.c (output_rule_data): Use quotearg to output the
16895 token strings.
16896
16897 2001-12-13 Paul Eggert <eggert@twinsun.com>
16898
16899 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
16900 Do not infringe on the global user namespace when using C++.
16901 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
16902 All uses of `fprintf' and `stderr' changed.
16903
16904 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
16905
16906 2001-12-13 Akim Demaille <akim@epita.fr>
16907
16908 The computation of nullable is broken: it doesn't handle empty
16909 RHS's properly.
16910
16911 * tests/torture.at (GNU AWK Grammar): New.
16912 * tests/sets.at (Nullable): New.
16913 * src/nullable.c (set_nullable): Instead of blindly looping over
16914 `ritems', loop over the rules, and then over their rhs's.
16915
16916 Work around Autotest bugs.
16917
16918 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
16919 frame, because Autotest understand lines starting with a `+' as
16920 traces from the shell. Then, they are not processed properly.
16921 Admittedly an Autotest bug, but we don't have time to wait for
16922 Autotest to catch up.
16923 * tests/regression.at (Broken Closure): Adjust to the new table
16924 frames.
16925 Move to...
16926 * tests/sets.at: here.
16927
16928 2001-12-13 Akim Demaille <akim@epita.fr>
16929
16930 * src/closure.c (closure): Use nrules instead of playing tricks
16931 with BITS_PER_WORD.
16932
16933 2001-12-13 Akim Demaille <akim@epita.fr>
16934
16935 * src/print.c (print_actions): Output the handling of `$' as the
16936 traces do: shifting the token EOF. Before EOF was treated as a
16937 nonterminal.
16938 * tests/regression.at: Adjust some tests.
16939 * src/print_graph.c (print_core): Complete the set of items via
16940 closure. The next-to-final and final states are still unsatisfying,
16941 but that's to be addressed elsewhere.
16942 No longer output the rule numbers, but do output the state number.
16943 A single loop for the shifts + gotos is enough, but picked a
16944 distinct color for each.
16945 (print_graph): Initialize and finalize closure.
16946
16947 2001-12-13 Akim Demaille <akim@epita.fr>
16948
16949 * src/reader.c (readgram): Remove dead code, an strip useless
16950 braces.
16951 (get_type): Remove, unused.
16952
16953 2001-12-12 Akim Demaille <akim@epita.fr>
16954
16955 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
16956 on that of lib/error.c.
16957
16958 2001-12-12 Akim Demaille <akim@epita.fr>
16959
16960 Some hosts don't like `/' in includes.
16961
16962 * src/system.h: Include libgettext.h without qualifying the path.
16963 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
16964 $(top_srcdir).
16965
16966 2001-12-11 Marc Autret <autret_m@epita.fr>
16967
16968 * src/output.c (output_parser): Remove useless muscle.
16969
16970 2001-12-11 Marc Autret <autret_m@epita.fr>
16971
16972 * src/bison.simple: Remove #line just before %%epilogue. It
16973 is now handled in ...
16974 * src/reader.c (read_additionnal_code): Add the output of a
16975 #line for the epilogue.
16976
16977 2001-12-10 Marc Autret <autret_m@epita.fr>
16978
16979 * src/reader.c (copy_definition): Re-use CPP-outed code which
16980 replace precedent remove.
16981 * src/bison.simple: Remove #line before %%prologue because
16982 %%input-line is wrong at this time.
16983
16984 2001-12-10 Marc Autret <autret_m@epita.fr>
16985
16986 * src/reader.c (symbols_output): Clean up.
16987 * src/output.c (output_gram, output): Clean up.
16988
16989 2001-12-10 Akim Demaille <akim@epita.fr>
16990
16991 * src/lalr.c (initialize_lookaheads): New. Extracted from...
16992 * src/LR0.c (set_state_table): here.
16993 * src/lalr.c (lalr): Call it.
16994
16995 2001-12-10 Akim Demaille <akim@epita.fr>
16996
16997 * src/state.h (shifts): Remove the `number' member: shifts are
16998 attached to state, hence no longer need to be labelled with a
16999 state number.
17000
17001 2001-12-10 Akim Demaille <akim@epita.fr>
17002
17003 Now that states have a complete set of members, the linked list of
17004 shifts is useless: just fill directly the state's shifts member.
17005
17006 * src/state.h (shifts): Remove the `next' member.
17007 * src/LR0.c (first_state, last_state): Remove.
17008 Adjust the callers.
17009 (augment_automaton): Don't look for the shifts that must be added
17010 a shift on EOF: it is those of the state we looked for! But now,
17011 since shifts are attached, it is no longer needed to looking
17012 merely by its id: its number.
17013
17014 2001-12-10 Akim Demaille <akim@epita.fr>
17015
17016 * src/LR0.c (augment_automaton): Better variable locality.
17017 Remove an impossible branch: if there is a state corresponding to
17018 the start symbol being shifted, then there is shift for the start
17019 symbol from the initial state.
17020
17021 2001-12-10 Akim Demaille <akim@epita.fr>
17022
17023 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17024 only when appropriate: when insert_start_shifting_state' is not
17025 invoked.
17026 * tests/regression.at (Rule Line Numbers): Adjust.
17027
17028 2001-12-10 Akim Demaille <akim@epita.fr>
17029
17030 * src/LR0.c (augment_automaton): Now that all states have shifts,
17031 merge the two cases addition shifts to the initial state.
17032
17033 2001-12-10 Akim Demaille <akim@epita.fr>
17034
17035 * src/lalr.c (set_state_table): Move to...
17036 * src/LR0.c: here.
17037 * src/lalr.c (lalr): Don't call it...
17038 * src/LR0.c (generate_states): do it.
17039 * src/LR0.h (first_state): Remove, only the table is used.
17040
17041 2001-12-10 Akim Demaille <akim@epita.fr>
17042
17043 * src/LR0.h (first_shift, first_reduction): Remove.
17044 * src/lalr.c: Don't use first_shift: find shifts through the
17045 states.
17046
17047 2001-12-10 Akim Demaille <akim@epita.fr>
17048
17049 * src/LR0.c: Attach shifts to states as soon as they are
17050 computed.
17051 * src/lalr.c (set_state_table): Instead of assigning shifts to
17052 state, just assert that the mapping was properly done.
17053
17054 2001-12-10 Akim Demaille <akim@epita.fr>
17055
17056 * src/LR0.c (insert_start_shift): Rename as...
17057 (insert_start_shifting_state): this.
17058 (insert_eof_shifting_state, insert_accepting_state): New.
17059 (augment_automaton): Adjust.
17060 Better locality of the variables.
17061 When looking if the start_symbol is shifted from the initial
17062 state, using `while (... symbol != start_symbol ...)' sounds
17063 better than `while (... symbol < start_symbol ...)': If fail
17064 to see how the order between symbols could be relevant!
17065
17066 2001-12-10 Akim Demaille <akim@epita.fr>
17067
17068 * src/getargs.h: Don't declare `spec_name_prefix' and
17069 `spec_file_prefix', declared by src/files.h.
17070 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17071 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17072 * src/output.c (prepare): Adjust.
17073 * src/reader.c (symbols_output): Likewise.
17074 * src/vmsgetargs.c: Vaguely adjust, but who cares?
17075
17076 2001-12-10 Akim Demaille <akim@epita.fr>
17077
17078 * src/muscle_tab.c (muscle_init): NULL is a better default than
17079 `"0"'.
17080
17081 2001-12-10 Akim Demaille <akim@epita.fr>
17082
17083 * src/reader.c (reader): Calling symbols_output once is enough.
17084
17085 2001-12-10 Akim Demaille <akim@epita.fr>
17086
17087 Now that states have a complete set of members, the linked list of
17088 reductions is useless: just fill directly the state's reductions
17089 member.
17090
17091 * src/state.h (struct reductions): Remove member `number' and
17092 `next'.
17093 * src/LR0.c (first_reduction, last_reduction): Remove.
17094 (save_reductions): Don't link the new reductions, store them in
17095 this_state.
17096 * src/lalr.c (set_state_table): No need to attach reductions to
17097 states, it's already done.
17098 * src/output.c (output_actions): No longer free the shifts, then
17099 the reductions, then the states: free all the states and their
17100 members.
17101
17102 2001-12-10 Akim Demaille <akim@epita.fr>
17103
17104 * src/options.c (OPTN, DRTV, BOTH): New.
17105 (option_table): Use them.
17106
17107 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
17108 the job of system.h.
17109 * src/options.c: Don't include stdio.h and xalloc.h for the same
17110 reasons.
17111
17112 2001-12-10 Akim Demaille <akim@epita.fr>
17113
17114 * src/output.c (output, prepare): Make sure the values of the
17115 muscles `action' and `prologue' are 0-terminated.
17116
17117 2001-12-10 Akim Demaille <akim@epita.fr>
17118
17119 Clean up GCC warnings.
17120
17121 * src/reader.c (copy_action): `buf' is not used.
17122 (parse_skel_decl): Be static.
17123 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
17124 * src/options.h (create_long_option_table): Have a real prototype.
17125 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
17126 (hash_delete_at): Return const void *.
17127 Adjust casts to preserve the const.
17128
17129 2001-12-10 Akim Demaille <akim@epita.fr>
17130
17131 * configure.in: Require 2.52g.
17132 M4 is not needed, but AUTOM4TE is.
17133 * m4/m4.m4: Remove.
17134 * tests/Makefile.am: Adjust.
17135
17136 2001-12-10 Akim Demaille <akim@epita.fr>
17137
17138 One structure for states is enough, even though theoretically
17139 there are LR(0) states and LALR(1) states.
17140
17141 * src/lalr.h (state_t): Remove.
17142 (state_table): Be state_t **, not state_t *.
17143 * src/state.h (core, CORE_ALLOC): Rename as...
17144 (state_t, STATE_ALLOC): this.
17145 Add the LALR(1) members: shifts, reductions, errs.
17146 * src/LR0.c (state_table): Rename as...
17147 (state_hash): this, to avoid name clashes with the global
17148 `state_table'.
17149 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
17150 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
17151
17152 2001-12-10 Akim Demaille <akim@epita.fr>
17153
17154 Bison dumps core on bash.y.
17155 Reported by Pascal Bart.
17156
17157 * src/warshall.c (bitmatrix_print): New.
17158 (TC): Use it.
17159 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
17160 j must be the outer loop.
17161 * tests/regression.at (Broken Closure): New.
17162
17163 2001-12-05 Akim Demaille <akim@epita.fr>
17164
17165 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
17166 its argument.
17167 Reported by Peter Hamorsky.
17168
17169 2001-12-05 Akim Demaille <akim@epita.fr>
17170
17171 * src/conflicts.c (err_table): Remove.
17172 (resolve_sr_conflict): Adjust.
17173 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
17174 Rename as...
17175 (state_t.reductions, state_t.shifts): this.
17176
17177 2001-12-05 Akim Demaille <akim@epita.fr>
17178
17179 * src/reduce.c (reduce_grammar_tables): No longer disable the
17180 removal of useless rules via CPP but via `if (0)', so that the
17181 compiler still check the code is valid.
17182 For instance, it should have noticed `rline' no longer exists: use
17183 the `line' member of rule_t.
17184 * src/gram.c (dummy, rline): Remove, unused.
17185
17186 2001-12-05 Akim Demaille <akim@epita.fr>
17187
17188 * src/output.c (pack_vector): Use assert, not berror.
17189 * src/main.c (berror): Remove, unused.
17190
17191 2001-12-05 Akim Demaille <akim@epita.fr>
17192
17193 New experimental feature: if --verbose --trace output all the
17194 items of a state, not only its kernel.
17195
17196 * src/print.c (print_core): If `trace_flag', then invoke closure
17197 before outputting the items of the state (print_core is no longer
17198 a correct name them).
17199 (print_results): Invoke new_closure/free_closure if needed.
17200
17201 2001-12-05 Akim Demaille <akim@epita.fr>
17202
17203 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
17204 * src/closure.c, src/closure.h (itemsetsize): Rename as...
17205 (nitemset): for consistency with the rest of the project.
17206
17207 2001-12-05 Akim Demaille <akim@epita.fr>
17208
17209 * src/closure.c (print_closure): Improve.
17210 (closure): Use it for printing input and output.
17211
17212 2001-12-05 Akim Demaille <akim@epita.fr>
17213
17214 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
17215 indexed by nonterminals.
17216
17217 2001-12-05 Akim Demaille <akim@epita.fr>
17218
17219 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
17220 what it was!).
17221 * src/warshall.h: Remove accidental duplication of the content.
17222
17223 2001-12-05 Akim Demaille <akim@epita.fr>
17224
17225 * src/closure.c (set_fderives): De-obfuscate.
17226
17227 2001-12-05 Akim Demaille <akim@epita.fr>
17228
17229 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
17230
17231 2001-12-05 Akim Demaille <akim@epita.fr>
17232
17233 * src/closure.c (set_firsts): De-obfuscate.
17234
17235 2001-12-05 Akim Demaille <akim@epita.fr>
17236
17237 * src/output.c (action_row): De-obfuscate
17238 using the good o' techniques: arrays not pointers, variable
17239 locality, BITISSET, RESETBIT etc.
17240
17241 2001-12-05 Akim Demaille <akim@epita.fr>
17242
17243 Pessimize the code to simplify it: from now on, all the states
17244 have a valid SHIFTS, which NSHIFTS is possibly 0.
17245
17246 * src/LR0.c (shifts_new): Be global and move to..
17247 * src/state.c, src/state.h: here.
17248 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
17249 * src/print_graph: Adjust.
17250
17251 2001-12-05 Akim Demaille <akim@epita.fr>
17252
17253 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
17254 * src/conflicts.c: Use it.
17255 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
17256 incorrectly ``simplified''.
17257
17258 2001-12-05 Akim Demaille <akim@epita.fr>
17259
17260 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
17261 using the good o' techniques: arrays not pointers, variable
17262 locality, BITISSET, RESETBIT etc.
17263
17264 2001-12-05 Akim Demaille <akim@epita.fr>
17265

17270
17271 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
17272 (print_reductions): De-obfuscate using the good o' techniques:
17273 arrays not pointers, variable locality, BITISSET.
17274
17275 2001-12-05 Akim Demaille <akim@epita.fr>
17276
17277 * src/conflicts.c (print_reductions): Arrays, not pointers.
17278 Use BITISSET.
17279
17280 2001-12-05 Akim Demaille <akim@epita.fr>
17281
17282 * src/conflicts.c (print_reductions): Pessimize, but clarify.
17283
17284 2001-12-05 Akim Demaille <akim@epita.fr>
17285
17286 * src/conflicts.c (print_reductions): Improve variable locality.

17299 * src/lalr.c: Use them.
17300
17301 2001-12-05 Akim Demaille <akim@epita.fr>
17302
17303 * src/LR0.c (augment_automaton): Formatting changes.
17304 Better variable locality.
17305
17306 2001-12-05 Akim Demaille <akim@epita.fr>
17307
17308 * src/lalr.c (matrix_print): New.

17311
17312 2001-12-05 Akim Demaille <akim@epita.fr>
17313
17314 * src/lalr.c (maxrhs): Move to...
17315 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
17316 * src/lalr.c (build_relations): Adjust.
17317
17318 2001-12-05 Akim Demaille <akim@epita.fr>
17319
17320 * src/lalr.c (transpose): Free the memory allocated to the
17321 argument, as it is replaced by the results by the unique caller.
17322 (build_relations): Merely invoke transpose: it handles the memory
17323 deallocation.
17324 Improve variable locality.
17325 Avoid variables used as mere abbreviations.
17326 (compute_lookaheads): Use arrays instead of pointers.
17327
17328 2001-12-05 Akim Demaille <akim@epita.fr>

17344 2001-12-05 Akim Demaille <akim@epita.fr>
17345
17346 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
17347 the handling of squeue.
17348 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17349
17350 2001-12-05 Akim Demaille <akim@epita.fr>
17351
17352 Because useless nonterminals are now kept alive (instead of being
17353 `destroyed'), we now sometimes examine them, and store information
17354 related to them. Hence we need to know their number, and adjust
17355 memory allocations.
17356
17357 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
17358 static.
17359 * src/LR0.c (allocate_itemsets): The memory allocated to
17360 `symbol_count' was used for two different purpose: once to count
17361 the number of occurrences of each symbol, and later reassigned to
17362 `shift_symbol', containing the symbol that can be shifted from a
17363 given state.
17364 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17365 only, and...
17366 (new_itemsets): Allocate `shift_symbol' here.
17367 (allocate_itemsets): symbol_count includes useless nonterminals.
17368 Make room for them.
17369 (free_storage): Use `free', not `XFREE', for pointers that cannot
17370 be null.
17371
17372 2001-12-05 Akim Demaille <akim@epita.fr>
17373
17374 * src/nullable.c (set_nullable): Deobfuscate the handling of
17375 ritem.
17376 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17377
17378 2001-12-05 Akim Demaille <akim@epita.fr>
17379
17380 * src/gram.c, src/gram.h (ritem_print): New.
17381 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
17382 (This useless function was defined only to work around VMS linkers
17383 that can't handle compilation units with variables only).
17384 * src/reduce.c (dump_grammar): Use it to trace the construction of
17385 ritem.
17386
17387 2001-12-04 Paul Eggert <eggert@twinsun.com>
17388
17389 * src/bison.simple (union yyalloc): Change member names
17390 to be the same as the stack names.
17391 (yyparse): yyptr is now union yyalloc *, not char *.
17392 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
17393 and may generate better code on some machines.
17394 (yystpcpy): Use prototype if __STDC__ is defined, not just
17395 if __cplusplus is defined.
17396
17397 2001-11-30 Akim Demaille <akim@epita.fr>
17398
17399 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
17400 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
17401 Gettext doesn't compile cleanly, and dies with -Werror.
17402 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
17403 Include WARNING_CFLAGS here.
17404 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
17405 before being defined.
17406
17407 2001-11-27 Paul Eggert <eggert@twinsun.com>
17408
17409 * lib/quotearg.h (quotearg_n, quotearg_n_style):
17410 First arg is int, not unsigned.
17411 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
17412 (SIZE_MAX, UINT_MAX): New macros.
17413 (quotearg_n_options): Abort if N is negative.
17414 Avoid overflow check on hosts where size_t is 64 bits and int
17415 is 32 bits, as overflow is impossible there.
17416 Fix off-by-one typo that caused unnecessary reallocation.
17417
17418 2001-11-29 Paul Eggert <eggert@twinsun.com>
17419

17425 * src/bison.simple:
17426 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
17427 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
17428 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
17429
17430 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
17431 on user names when possible.
17432
17433 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
17434 Simplify test for whather <alloca.h> exists.
17435
17436 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
17437
17438 (<stdio.h>): Include if YYDEBUG.
17439
17440 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
17441 ! defined (yyoverflow) && ! defined (yymemcpy).
17442
17443 (yymemcpy, yyparse): Rename local variables as needed so that
17444 they all begin with 'yy'.
17445
17446 (yystrlen, yystpcpy): New functions.
17447
17448 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
17449 All uses changed.
17450
17451 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
17452 instead of relying on string.h functions. Use YYSTACK_ALLOC
17453 and YYSTACK_FREE instead of malloc and free.
17454
17455 2001-11-30 Akim Demaille <akim@epita.fr>
17456
17457 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
17458 before their first uses.

17464
17465 2001-11-30 Akim Demaille <akim@epita.fr>
17466
17467 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
17468 if body instead of `;' to pacify GCC's warnings.
17469
17470 2001-11-30 Akim Demaille <akim@epita.fr>
17471
17472 Instead of mapping the LHS of unused rules to -1, keep the LHS
17473 valid, but flag the rules as invalid.
17474
17475 * src/gram.h (rule_t): `useful' is a new member.
17476 * src/print.c (print_grammar): Adjust.
17477 * src/derives.c (set_derives): Likewise.
17478 * src/reader.c (packgram, reduce_output): Likewise.

17485 * src/print.c (print_results, print_grammar): Likewise.
17486 * tests/regression.at (Rule Line Numbers)
17487 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
17488
17489 2001-11-30 Akim Demaille <akim@epita.fr>
17490
17491 * src/reduce.c (nonterminals_reduce): Instead of throwing away
17492 useless nonterminals, move them at the end of the symbol arrays.
17493 (reduce_output): Adjust.
17494 * tests/reduce.at (Useless Nonterminals): Adjust.
17495
17496 2001-11-30 Akim Demaille <akim@epita.fr>
17497
17498 * src/reduce.c: Various comment/formatting changes.
17499 (nonterminals_reduce): New, extracted from...
17500 (reduce_grammar_tables): here.
17501 (reduce_grammar): Call nonterminals_reduce.
17502
17503 2001-11-29 Paul Eggert <eggert@twinsun.com>

17506 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
17507 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
17508 New macros.
17509 (union yyalloc): New type.
17510 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
17511 an arbitrary restriction on hosts where size_t is wider than int.
17512
17513 (yyparse): Don't dump core if alloca or malloc fails; instead, report
17514 a parser stack overflow. Allocate just one block of memory for all
17515 three stacks, instead of allocating three blocks; this typically is
17516 faster and reduces fragmentation.
17517
17518 Do not limit the number of items in the stack to a value that fits
17519 in 'int', as this is an arbitrary limit on hosts with 64-bit
17520 size_t and 32-bit int.
17521
17522 2001-11-29 Marc Autret <autret_m@epita.fr>

17576
17577 * src/closure.c (closure): Instead of looping over word in array

17581
17582 * src/closure.c (closure): No longer optimize the special case
17583 where all the bits of `ruleset[r]' are set to 0, to make the code
17584 clearer.
17585
17586 2001-11-28 Akim Demaille <akim@epita.fr>
17587
17588 * src/closure.c (closure): `r' and `c' are new variables, used to
17589 de-obfuscate accesses to RULESET and CORE.
17590

17592

17848
17849 * src/vcg.c: You do the output, so you are responsible of the
17850 handling of VCG syntax, in particular: use quotearg.
17851 * src/print_graph.c: Don't.
17852 (print_actions): Don't output the actions as part of the nodes,
17853 since that's the job of the edges.

17947 * tests/calc.at, tests/output.at, tests/regression.at,
17948 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
17949 now the tests are run in private dirs, therefore AC_CLEANUP and
17950 family can be simplified to 0-ary.
17951 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
17952 use abs. path to find config.h.
17953 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
17954 stderr, there can be way too much random noise.
17955 Instead pass -Werror to GCC and rely on the exit status.
17956 Reported by Wolfram Wagner.

17959
17960 * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be

17971
17972 * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):

17975 braces to pacify GCC's warnings for `if () if () {} else {}'.
17976 * src/lex.c (parse_percent_token): Replace equal_offset with
17977 arg_offset.
17978 arg is const.

18076 * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
18077 with yyltype/YYLTYPE. This allows inclusion of the generated
18078 header within the parser if the compiler, such as GGC, accepts
18079 multiple equivalent #defines.
18080 From Akim.

19332 New, from fileutils 4.0.37.

19373 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

19376 instead of returning a token.
19377 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
19378 * src/reader.c (read_declarations): Adjust.
19379 * src/files.c (open_files): Don't call `compute_base_names', don't
19380 compute `attrsfile' since they depend upon data which might be
19381 *in* the input file now.
19382 (output_files): Do it here.
19383 * src/output.c (output_headers): Document the fact that this patch
19384 introduces a guaranteed SEGV for semantic parsers.

19411 2000-12-20 Akim Demaille <akim@epita.fr>
19412
19413 * src/files.c (open_files): Actually the `.output' file is based

19416
19417 2000-12-20 Akim Demaille <akim@epita.fr>

19443 (stringappend): Be just like strcat but allocate.
19444 (base_names): Eve out from open_files.
19445 Try to simplify the rather hairy computation of base_name and
19446 short_base_name.
19447 (open_files): Use it.
19448 * tests/suite.at (Checking output file names): New test.
19449

19459 2000-12-19 Akim Demaille <akim@epita.fr>
19460

19465
19466 2000-12-19 Akim Demaille <akim@epita.fr>
19467

19486 2000-12-19 Akim Demaille <akim@epita.fr>
19487
19488 * src/files.c (open_files): Yipee! We no longer need all the code
19489 looking for `/tmp' since we have no tmp file.
19490
19491 2000-12-19 Akim Demaille <akim@epita.fr>
19492

19519
19520 * lib/obstack.h: Formatting changes.
19521 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
19522 prevents type checking.
19523 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
19524 cast the value to (void *): assigning a `foo *' to a `void *'
19525 variable is valid.

19527 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

19543
19544 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
19545 macros.

19570 * src/output.c (output): Remove useless variables.
19571 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
19572 argument `data' for consistency with the prototypes.
19573 Qualify it `const'.
19574 (obstack_copy, obstack_copy0): Rename the second argument as
19575 `address' for consistency. Qualify it `const'.
19576 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
19577 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
19578 `const' their input argument (`data' or `address').
19579 Adjust the corresponding macros to include `const' in casts.
19580
19581 2000-11-03 Akim Demaille <akim@epita.fr>
19582
19583 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
19584 s/PFILE1/BISON_HAIRY/.
19585 Adjust dependencies.
19586
19587 2000-11-03 Akim Demaille <akim@epita.fr>
19588
19589 For some reason, this was not applied.
19590
19591 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

19605 (output_files): this.
19606 Use `obstack_save'.
19607 * src/main.c (main): Don't use `atexit' to register `done', since
19608 it no longer has to remove tmp files, just call `output_files'
19609 when there are no errors.

19612

19631
19632 2000-11-01 Akim Demaille <akim@epita.fr>
19633

19643
19644 Introduce obstacks.

19678
19679 2000-10-16 Akim Demaille <akim@epita.fr>
19680
19681 * src/reader.c (copy_comment2): Expect the input stream to be on
19682 the `/' which is suspected to open a comment, instead of being
19683 called after `//' or `/*' was read.
19684 (copy_comment, copy_definition, parse_union_decl, copy_action)
19685 (copy_guard): Adjust.
19686
19687 2000-10-16 Akim Demaille <akim@epita.fr>

19712
19713 2000-10-04 Akim Demaille <akim@epita.fr>
19714
19715 When a literal string is used to define two different tokens,
19716 `bison -v' segfaults.
19717 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
19718

19727 of `buffer'.
19728 From Neil Booth.
19729
19730 2000-10-02 Paul Eggert <eggert@twinsun.com>
19731
19732 * bison.s1 (yyparse): Assign the default value
19733 unconditionally, to avoid a GCC warning and make the parser a
19734 tad smaller.

19737
19738 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
19739 options.
19740
19741 2000-10-02 Akim Demaille <akim@epita.fr>
19742
19743 * src/derives.c, src/print.c, src/reduce.c: To ease the
19744 translation, move some `\n' out of the translated strings.
19745
19746 2000-10-02 Akim Demaille <akim@epita.fr>
19747
19748 The location tracking mechanism is precious for parse error
19749 messages. Nevertheless, it is enabled only when `@n' is used in
19750 the grammar, which is a different issue (you can use it in error
19751 message, but not in the grammar per se). Therefore, there should
19752 be another means to enable it.
19753
19754 * src/getargs.c (getargs): Support `--locations'.
19755 (usage): Report it.
19756 * src/getargs.h (locationsflag): Export it.
19757 * src/lex.c (percent_table): Support `%locations'.
19758 * src/reader.c (yylsp_needed): Remove this variable, now replaced
19759 with `locationsflag'.
19760 * doc/bison.texinfo: Document `--locations' and `%locations'.
19761 Sort the options.
19762 * tests/calc.m4: Test it.
19763
19764 For regularity of the names, replace each
19765 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
19766 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
19767 In addition replace each `flag' with `_flag'.
19768
19769 2000-10-02 Akim Demaille <akim@epita.fr>
19770
19771 Also test parse error messages, including with YYERROR_VERBOSE.
19772
19773 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
19774 associative).
19775 Use it to check the computations.
19776 Use it to check `nonassoc' is honored.
19777 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
19778 `--yyerror-verbose'.
19779 (_AT_CHECK_CALC): Adjust to this option.
19780 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
19781
19782 2000-10-02 Akim Demaille <akim@epita.fr>
19783
19784 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19785 the latter demonstrates a flaw in the handling of non debugging
19786 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19787 was used in order to simplify:
19788
19789 #if YYDEBUG
19790 if (yydebug)
19791 {
19792 ...
19793 }
19794 #endif
19795
19796 into
19797
19798 if (yydebug)
19799 {
19800 ...
19801 }
19802
19803 unfortunately this leads to a CPP conflict when
19804 `--name-prefix=foo' is used since it produces `#define yydebug
19805 foodebug'.
19806
19807 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
19808 (YYDPRINTF): New macro.
19809 Spread its use.
19810 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
19811 the bison options.
19812 Also test `--verbose', `--defines' and `--name-prefix'.
19813
19814 2000-10-02 Akim Demaille <akim@epita.fr>
19815
19816 Improve the readability of the produced parsers.
19817
19818 * src/bison.s1: Formatting changes.
19819 Improve the comment related to the `$' mark.
19820 (yydefault): Don't fall through to `yyresume': `goto' there.
19821 * src/output.c (output_parser): When the `$' is met, skip the end
19822 of its line.
19823 New variable, `number_of_dollar_signs', to check there's exactly
19824 one `$' in the parser skeleton.
19825
19826 2000-10-02 Akim Demaille <akim@epita.fr>
19827
19828 * lib/xstrdup.c: New file, from the fileutils.
19829 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
19830 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
19831 instead of strlen + xmalloc + strcpy.
19832 * src/symtab.c (copys): Remove, use xstrdup instead.
19833
19834 2000-10-02 Akim Demaille <akim@epita.fr>
19835
19836 * src/gram.h (associativity): New enum type which replaces the
19837 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
19838 `right_assoc', `left_assoc' and `non_assoc'.
19839 Adjust all dependencies.
19840 * src/reader.c: Formatting changes.
19841 (LTYPESTR): Don't define it, use it as a literal in
19842 `reader_output_yylsp'.
19843 * src/symtab.h (symbol_class): New enum type which replaces the
19844 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
19845 `sunknown', `stoken and `snterm'.
19846
19847 2000-10-02 Akim Demaille <akim@epita.fr>
19848
19849 * src/getargs.c (fixed_outfiles): Rename as...
19850 (yaccflag): for consistency and accuracy.
19851 Adjust dependencies.
19852
19853 2000-10-02 Akim Demaille <akim@epita.fr>
19854
19855 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19856 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19857 difficult and introduced a lot of core dump. It turns out that
19858 Bison used an implementation of `xmalloc' based on `calloc', and
19859 at various places it does depend upon the initialization to 0. I
19860 have not tried to isolate the pertinent places, and all the former
19861 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
19862 someone should address this issue.
19863
19864 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
19865 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

19961 output_short_table.
19962
19963 2000-10-02 Akim Demaille <akim@epita.fr>
19964
19965 `user_toknums' is output as a `short[]' in `output.c', while it is
19966 defined as a `int[]' in `reader.c'. For consistency with the

20009 inclusion.
20010 Don't define PARAMS.
20011 * src/system.h: Define PARAMS.

20013 purpose of config.h. system.h must not try to fix wrong
20014 definitions in config.h.
20015
20016 2000-09-20 Akim Demaille <akim@epita.fr>

20231
20232 Change the handling of @s so that they behave exactly like $s.
20233 There is now a pseudo variable @$ (readble and writable), location
20234 of the lhs of the rule (by default ranging from the location of
20235 the first symbol of the rhs, to the location of the last symbol,
20236 or, if the rhs is empty, YYLLOC).
20237
20238 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
20239 yyval.
20240 (yyparse): When providing a default semantic action, provide a

20262
20263 * src/output.c (output_rule_data): Output the documentation of

20269
20270 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
20271 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
20272 One `#if YYDEBUG' remains, since it uses variables which are
20273 defined only if `YYDEBUG != 0'.
20274
20275 2000-03-16 Akim Demaille <akim@epita.fr>

20292
20293 * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by
20294 src/makefile.am.
20295 (VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED.

20992 (lex): Use literalchar.
20993 (lex): Implemented "..." tokens.
20994 (literalchar, lex, parse_percent_token): Made tokenbuffer
20995 always contain the token. This includes growing the token
20996 buffer while reading an integer.
20997 (parse_percent_token): Replaced if-else statement with percent_table.
20998 (parse_percent_token): Added % declarations as another
20999 way to specify the flags -n, -l, and -r. Also added hooks for
21000 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21001 major changes to files.c.
21002 (lex) Retain in the incoming stream a character following
21003 an incorrect '/'.
21004 (skip_white_space, lex): Revised most error messages
