78 * NEWS (2.3b+): Rename to...
79 (?.?): ... this because we're dropping the "+" version naming scheme,
80 but, in general, we still can't be sure of our next release name.
81 * bootstrap: Add a quick hack to remove from .gitignore the
82 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
83 entry. This should really be fixed in gnulib instead.
84 * bootstrap.conf (gnulib_modules): Add gnumakefile.

116 Fix some .gitignore and .cvsignore problems.
117 * bootstrap (insert_sorted_if_absent): Replace all uses with...

119 .gitignore entries before passing them to insert_sorted_if_absent.
120 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that

138 * bootstrap.conf (gnulib_modules): Add unsetenv.
139 * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
140 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
142 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
143 the first argument because it may become position-dependent, and unset
144 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
145 Add comments explaining these issues in more detail.

209 Revert prior patch, by working around autoconf regression.
210 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
211 ("Output file name: ("): Uncomment test.
212 ("Output file name: )"): Likewise.
213 Based on an idea from Noah Misch.

233 * bootstrap: Update gnulib CVS repository URL.
234 (symlink_to_dir): Encapsulate the code that guarantees the destination
235 directory exists into...
236 (check_dst_dir): ... this new function, and...
237 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
238 fail when copying files into lib/uniwidth/.
239 * src/output.c (prepare_symbols): When writing yytname muscles, where
240 symbol names will be encoded in C-string literals, tell quotearg to
241 escape trigraphs. This used to be the default in gnulib.
242 * tests/regression.at (Token definitions): Because of the change in
243 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
244 escapes trigraphs in symbol names. Thus, yytname no longer has
245 trigraphs unnecessarily doubly escaped. Update test case output.
246 Extend test case to be sure Bison's own error messages will no longer
247 have trigraphs in symbol names unnecessarily escaped once.

263 consistency. Update the -g and -x entries now that they take
264 arguments. Use brackets to indicate optional arguments.
265 * src/getargs.c (usage): Explain the relationship between arguments of
266 long and short options more completely. Document --defines and -d
267 separately since the former takes an argument but, for POSIX Yacc, the
269 (short_options): Let -W take an optional argument like --warnings.

975 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
976 after printing the error directive so that M4 doesn't report subsequent
977 problems that are induced by this problem.
978 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
979 instead of just in them. Recognize @\n in both places. Both expand to
980 the empty string. Needed by b4_cat.
981 * tests/skeletons.at (Complaining during macro argument expansion):
983 (Fatal errors make M4 exit immediately): New test case.
985 2007-10-04 Joel E. Denny <jdenny@ces.clemson.edu>

1006 2007-09-25 Joel E. Denny <jdenny@ces.clemson.edu>
1008 Replace `%push-parser' and `%push-pull-parser' with
1009 `%define push_pull "push"' and `%define push_pull "both"'.

1012 Pull Parser Function, Parser Create Function, Parser Delete Function):
1013 Update declarations.

1019 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
1021 * data/push.c: ... to here and compute them from the value of the
1022 %define variable push_pull.
1023 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
1024 parsing requests here...
1025 * data/yacc.c: ... hack this to switch to push.c any time
1026 b4_use_push_pull_flag or the %define variable push_pull is set. This
1027 will go away when we mv push.c yacc.c.
1028 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
1029 push parsing is not supported since unused %define variables are
1031 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
1032 * src/muscle_tab.h (muscle_percent_define_check_values): Update

1064 Problem reported by Wojciech Polak.
1065 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.
1066 (xml_printf): Undo change I made on 21 September; that is,
1067 indent 2 spaces, not 1.
1069 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
1071 Pacify ./configure --enable-gcc-warnings.
1072 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
1073 `char const *' instead of `char *'.
1074 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
1075 local variable `sep'.
1077 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
1079 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
1081 * src/print-xml.c: Prefer "const" after types; that's more consistent.
1082 (xml_printf): Indent just 1 space for level.
1083 (e_char, xlate_char): Remove.
1084 (xml_escape_string): Rewrite to avoid undefined behavior (used
1085 storage that was freed from the stack).
1086 (xml_escape_n): Don't bother checking for subscript error.
1088 2007-09-21 Wojciech Polak <polak@gnu.org>

1133 * README-hacking: Likewise.
1137 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
1138 Bruno Haible <bruno@clisp.org>
1140 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
1141 and is a script that invokes bison. Tighten the code. Add comments.
1143 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>
1145 Spell "boolean" as "Boolean". Reported by Akim Demaille.
1146 * data/bison.m4 (b4_percent_define_flag_if): Fix complaint.

1148 * src/muscle_tab.c (muscle_percent_define_flag_if): Fix complaint.
1149 * tests/input.at (Boolean %define variables): Update output.
1150 * tests/skeletons.at (%define boolean variables: invalid skeleton
1151 defaults): Rename to...
1152 (%define Boolean variables: invalid skeleton defaults): ... this and
1155 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
1157 In impure push mode, don't allow more than one yypstate to be allocated
1158 since multiple impure parsers would corrupt yynerrs.
1159 * data/push.c (yypstate_allocated): New static global variable
1161 (yypull_parse): If yypstate_new returns 0, don't report it as memory
1162 exhaustion if yypstate_allocated is 1, but still return 2.
1163 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
1164 already 1. Otherwise, set it to 1.
1165 (yypstate_delete): Set it to 0.
1166 * tests/push.at (Push Parsing: Multiple impure instances): New test
1169 2007-08-17 Bob Rossi <bob@brasko.net>

1240 Get rid of broken %no-parser, -n, and --no-parser implementation and
1242 * TODO: Don't mention them.
1243 * doc/bison.1: Likewise.
1244 * doc/bison.texinfo (Decl Summary): Likewise.
1245 (Bison Options): Likewise.
1246 (Option Cross Key): Likewise.
1247 * src/getargs.c (no_parser_flag): Remove global variable.
1248 (usage): Don't print description of -n and --no-parser.
1249 (long_options): Remove --no-parser entry here.
1250 (getargs): Remove -n case in the switch here.
1251 * src/getargs.h (no_parser_flag): Remove extern.
1252 * tests/regression.at (Web2c Actions): Remove comment that mentions
1255 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
1257 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
1258 name user variables starting with `yy'. Just pass NULL instead of a
1259 dummy local &yylval to yypush_parse.
1260 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
1263 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
1265 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
1266 true since it's then always used regardless of whether yyoverflow is
1267 defined. Reported by Christian Burger at
1268 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
1269 * THANKS: Add Christian Burger.
1271 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1272 node names: say "Decl Summary" not "Bison Declaration Summary".
1274 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
1276 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
1277 determine whether this function has already complained about an invalid
1278 value for a %define boolean variable, don't check whether Bison has
1279 ever examined the value. As written, the check was a tautology.
1280 Instead, record and check for this complaint using a separate muscle.
1282 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
1284 Fix push parsing memory leak reported by Brandon Lucia at
1285 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
1286 * THANKS: Add Brandon Lucia.
1287 * data/push.c (yypstate_delete): Free the stack if it was reallocated
1288 but the parse never completed and thus freed it.
1289 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
1290 * tests/testsuite.at: Include push.at.
1291 * test/push.at: New.
1292 (Push Parsing: Memory Leak for Early Deletion): New test case.
1294 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
1296 Improve handling of multiple S/R conflicts in the same state and of S/R
1297 conflicts involving multiple reductions.
1298 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
1299 set for a state here or Bison will abort if it is reassigned on a
1300 later conflicted reduction in the same state.
1301 Similarly, don't finalize and assign the solved conflicts report here
1302 or it will be lost if it is reassigned on a later conflicted reduction
1304 (set_conflicts): Instead, assign them both here after all S/R conflicts
1305 in the state have been fully examined.
1306 * src/print.c (shift_set): Rename to...
1307 (no_reduce_set): ... this.
1308 (print_reductions): Update for rename, and add %nonassoc error action
1309 tokens to no_reduce_set so that, when printing the first remaining
1310 reduction on an error action token, the reduction is enclosed in
1312 (print_results): Update for rename.
1313 * tests/conflicts.at (Solved conflicts report for multiple reductions
1314 in a state): New test case.
1315 (%nonassoc error actions for multiple reductions in a state): New test
1318 * src/main.c (main): Don't depend on C99 features.
1320 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
1322 * build-aux/.cvsignore: Add compile.
1323 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
1326 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
1328 * bootstrap (slurp): Create target directories that don't exist.
1329 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
1331 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
1333 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
1335 * closure.c (closure): Likewise.
1336 * state.h (reductions): Comment sorting of rules.
1337 (state): Comment sorting of items.
1339 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
1341 Fix C++ test cases after recent Gnulib changes. Discussed starting at
1342 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
1343 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
1344 definition in order to avoid Gnulib headers since we don't use config.h
1346 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
1347 rather than AT_DATA so that config.h is included.
1349 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
1351 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
1352 instead of fprintf. Guard these functions with #if YYDEBUG instead of
1353 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
1354 and so that YYFPRINTF is guaranteed to be defined here.
1356 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
1358 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
1360 (muscle_percent_define_check_values): ... this more helpful function.
1361 Again, it's not used yet, but it will be.
1362 * src/muscle_tab.h: Likewise.
1364 Improve some comments in parser table construction.
1365 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
1366 (generate_states): Don't mention ruleset, which is internal to closure.
1367 * src/closure.c (closure): Explain sorting of core and itemset, which
1368 is required for this function to behave correctly.
1369 * src/closure.h (closure): Mention sorting.
1371 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
1373 * src/lalr.c (state_lookahead_tokens_count): For code readability,
1374 move the check for disabled transitions to an aver since conflict
1375 resolution hasn't happened yet.
1377 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
1378 labels a state as inconsistent just because it has error transitions.
1379 The original form of this check appeared in revision 1.1 of lalr.c,
1380 which was committed on 1991-12-21. Now (at least), changing the
1381 consistency label on such a state appears to have no useful effect in
1382 any of the places it is examined, which I enumerate below. The key
1383 point to understanding each item in this enumeration is that a state
1384 with an error transition is labelled consistent in the first place only
1385 if it has no rules, so the check cannot matter for states that have
1386 rules. (1) Labelling a state as inconsistent will cause set_conflicts
1387 to try to identify its conflicts, and a state must have *rules* to have
1388 conflicts. (2) Labelling a state as inconsistent will affect how
1389 action_row sets the default *rule* for the state. (3) Labelling a
1390 state as inconsistent will cause build_relations to add lookback edges
1391 to *rules* in that state.
1392 * src/state.h (struct state): Word the comment for member consistent
1395 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
1397 Don't depend on C99 features.
1398 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
1399 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
1400 * src/reader.c (check_and_convert_grammar): Fix for-loop.
1401 * src/state.c (state_mark_reachable_states): Fix for-loop.
1402 (state_remove_unreachable_states): Fix for-loop.
1404 Don't widen struct state with member reachable just to temporarily
1405 record reachability. Instead, use a local bitset.

1648 Undo my 2007-02-07 change, switching back to the c-strcase module
1649 introduced in the 2007-02-03 change. Bruno Haible reported that
1650 the 2007-02-07 change would be dangerous in Turkish if we add a
1651 language whose name contains "i", since "i" is not lowercase "I"
1653 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
1654 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
1655 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
1656 * m4/.cvsignore: Remove strcase.m4.
1657 * src/getargs.c: Revert 2007-02-07 change, as follows.

1659 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
1661 2007-02-11 Bruno Haible <bruno@clisp.org>
1663 Enable the Java related testsuite tests when the only Java compiler
1664 found is a gcj < 4.3. Discussed at
1665 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
1666 * configure.ac (gt_JAVACOMP): Don't specify a target_version.

1675 beginning of packgram to...
1676 (check_and_convert_grammar): ... here right before packgram is invoked
1677 so it's easier to write more complete comments, and remove redundant
1680 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
1682 As in semantic actions, make @$ in %initial-action, %destructor, and
1683 %printer imply %locations.
1684 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
1686 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...

1688 @$ in %destructor implies %locations,
1689 @$ in %printer implies %locations): ... these new test cases.
1691 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>

1694 now that gnulib strcase has been fixed.
1695 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
1696 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
1697 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
1698 * m4/.cvsignore: Add strcase.m4.
1699 * src/getargs.c: Revert 2007-02-03 change, as follows.
1700 Don't include c-strcase.h.
1701 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
1702 strcasecmp has "unspecified behavior" outside the POSIX locale,
1703 but it works fine in practice if at least one argument is ASCII,
1704 as is the case in Bison.
1706 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
1708 * tests/java.at: Skip tests if only one of javac/java is present.
1709 Reported by Joel E. Denny.
1710 * tests/atlocal.in: Adjust copyright years.

1714 * data/lalr1.java (Stack): Work around old verifiers that disallow
1715 access to the private fields of an inner class, from the outer class.
1716 We can make Stack's fields public because user code doesn't have access
1717 to the instance of Stack used by parse(). Reported by Paul Eggert.
1719 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1721 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
1722 the right spot for these files?
1723 * bootstrap.conf (gnulib_modules): Add c-strcase.
1724 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
1726 * src/getargs.c: Include c-strcase.h.
1727 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
1728 to avoid unspecified behavior.
1730 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
1732 * doc/bison.texinfo (Decl Summary): Correct typo.
1734 2007-01-30 Paolo Bonzini <bonzini@gnu.org>

1739 * data/java.m4: Adjust default definitions of %define variables.
1740 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according

1771 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
1772 at_directive_argv arguments so these no longer have to be global
1773 variables. Also, update the implementation for the following changes.
1774 (fail_for_at_directive_too_many_args,
1775 fail_for_at_directive_too_few_args): Add at_directive_name argument.
1776 (at_directive_name): Remove as at_directive_argv[0] will be used for

1789 (installed skeleton file names): ... this.
1791 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
1793 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1794 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
1795 Summary" not "Directives".
1796 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
1797 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
1798 since the former is now the more complete one.
1799 (Prologue Alternatives): Likewise and do the same for %defines.
1800 (Table of Symbols): Add summary of %code, add summary of %define, and
1801 move full %code documentation to...
1802 (Decl Summary): ... here for consistency with other entries in these
1804 Move %define entry in order to keep this list alphabetized.
1805 Reword %define entry a little to put less emphasis on the skeleton
1806 concept, which most users shouldn't have to think about.

1817 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
1819 Simplify implementation of unqualified %code, implement macros for
1820 uniform treatment of boolean %define flags. Document %define.

1863 Use per-type %printer.
1865 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1867 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

1875 2007-01-16 Akim Demaille <akim@epita.fr>
1877 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
1879 (Calc++ Scanner): Exit with failure if we can't open the input
1881 Accept "-" standing for stdin.
1882 (Calc++ Top Level): Print the result only if the parsing was
1885 2007-01-16 Akim Demaille <akim@epita.fr>
1887 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
1889 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
1890 and Joel E. Denny <jdenny@ces.clemson.edu>
1892 Clean up %define and %code implementation in M4 some. Most
1893 importantly, rename all related macros to be in the b4_percent_define
1894 and b4_percent_code namespaces. Also, complete support for `.' in
1895 %define variable names and %code qualifiers.
1896 * data/bison.m4 (b4_check_user_names): Check for special
1897 "SKELETON-NAMESPACE(name)" macros instead of using two nested
1899 (b4_get_percent_define, b4_get_percent_code): Rename to...
1900 (b4_percent_define_get, b4_percent_code_get): ... these.
1901 Extend documentation with examples.
1902 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
1903 b4_percent_define_skeleton_variables and
1904 b4_percent_code_skeleton_qualifiers.
1905 Expect any value for the %define variable `foo' to be stored in the
1906 macro named `b4_percent_define(foo)'; expect any %code blocks for the
1907 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
1908 expect any unqualified %code blocks to be stored in a macro named
1909 `b4_percent_code_unqualified'.
1910 Use m4_indir so that %define variable names and %code qualifiers can
1911 contain `.', which is allowed by the grammar parser.
1912 (b4_percent_define_default): New macro to set a default value for a
1914 (m4_wrap): Update wrapped code, and fix some underquoting.
1915 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
1916 Expect grammar uses of %define variables and %code qualifiers to be
1917 defined in b4_percent_define_user_variables and
1918 b4_percent_code_user_qualifiers.
1919 * data/c++.m4: Use b4_percent_define_default rather than
1920 m4_define_default. Fix some underquoting. Skeleton usage of %define
1921 variable define_location_comparison now implies skeleton usage of
1922 %define variable filename_type.
1923 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1924 data/push.c, data/yacc.c: Update macro names.
1925 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
1928 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
1930 DJGPP specific issues.
1932 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
1933 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
1935 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1937 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
1938 run parsers in all tests so that Valgrind is invoked during
1939 maintainer-check-valgrind.
1940 (Duplicate representation of merged trees): Free all semantic values.
1941 (Duplicated user destructor for lookahead): Likewise.
1943 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1945 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
1946 command-line prefix.
1947 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
1948 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
1949 miss Valgrind messages.
1950 (Exploding the Stack Size with Malloc): Likewise.
1952 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1954 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
1955 locals. Reported by Juan Manuel Guerrero at
1956 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
1957 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
1958 Fix some indentation also.
1959 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
1960 explaining this issue.
1962 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
1963 and Joel E. Denny <jdenny@ces.clemson.edu>
1965 Simplify union and prologue handling, and escape union and lex/parse
1966 params with digraphs.
1967 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
1968 values to the empty string since these are no longer guaranteed
1969 initialized by the front-end.
1970 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
1971 braces around b4_user_stype since this is no longer done by the
1973 * src/files.c, src/files.h (pre_prologue_obstack,
1974 post_prologue_obstack): Remove.
1975 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
1976 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
1977 with digraphs. This fixes lex params and parse params.
1978 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
1979 * src/output.c (prepare): Remove muscle insertion of the prologues.
1980 (output): Remove freeing of pre_prologue_obstack and
1981 post_prologue_obstack.
1982 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
1983 than prologue_augment for prologue parsing so you don't need prologue
1985 (grammar_declaration): For %union RHS, use `braceless' instead of
1986 "{...}" so that braces are already stripped and code is escaped with
1988 * src/reader.c (prologue_augment): Remove.
1989 (reader): Remove initialization of pre_prologue_obstack and
1990 post_prologue_obstack.
1991 * src/reader.h (prologue_augment): Remove.
1993 * data/c.m4: Remove stray parenthesis.
1995 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1997 Remove quotes from variables names in %define directives and from
1998 qualifiers in %code directives, and restrict the characters that are
1999 allowed in them to M4-friendly ones. For %define, continue to support
2000 the quoted form as a deprecated feature. Discussed starting at
2001 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
2002 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
2004 * doc/bison.texinfo (Prologue Alternatives): Update.
2005 (Decl Summary): In %defines entry, update mention of `%code requires'
2006 and `%code provides'.
2007 (C++ Location Values): Update %define uses.
2008 (Calc++ Parser Interface): Likewise.
2009 (Calc++ Parser): Likewise, and update `%code requires' uses.
2010 (Table of Symbols): Update %code documentation.
2011 * src/parse-gram.y (prologue_declaration): For %define variables, use
2012 `variable' instead of `STRING'.
2013 (grammar_declaration): For %code qualifiers, use `ID' instead of
2015 (variable): New nonterminal that takes an `ID' or a `STRING'.
2016 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
2018 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
2019 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
2020 (%define errors): Update %define uses.
2022 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2024 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
2025 instead of muscle_insert for %define values so that M4-special
2026 characters are replaced with digraphs.
2027 * tests/input.at (%define errors): Extend to check weird values.
2029 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2031 Instead of having skeletons declare all valid %define variables and
2032 %code qualifiers, provide macros that retrieve the associated values
2033 and build these lists automatically. Thus Bison will now warn when a
2034 variable or qualifier is not used by the skeleton in the current
2035 invocation regardless of whether it might sometimes be used by that
2036 skeleton in other invocations. Also, move all %define value macros to
2037 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2038 form, which is replaced by %code.
2039 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2040 (b4_check_user_names): ... this, and change the series of valid name
2041 arguments to a single list argument for names used in the skeleton
2042 similar to the existing list argument for names used in the grammar.
2043 Warn instead of complaining.
2044 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2045 values and %code code, to format %code code properly, and to build
2046 lists of all %define variables and %code qualifiers used in the
2047 skeleton: b4_skeleton_percent_define_variables and
2048 b4_skeleton_percent_code_qualifiers.
2049 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
2051 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
2052 the skeleton names lists can finish building first. In place of
2053 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
2054 expect the lists b4_user_percent_define_variables and
2055 b4_user_percent_code_qualifiers.
2056 * data/c++.m4: Where setting default values for b4_parser_class_name,
2057 b4_location_type, b4_filename_type, b4_namespace, and
2058 b4_define_location_comparison, update their names to the
2059 b4_percent_define_ namespace.
2060 * data/glr.c: Don't use b4_check_percent_define_variables and
2061 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2062 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
2063 (b4_parser_class_name, b4_namespace): Define these using
2064 b4_get_percent_define for parser_class_name and namespace.
2065 * data/location.cc: Use b4_get_percent_define.
2066 * data/push.c: Don't use b4_check_percent_define_variables and
2067 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2068 * data/yacc.c: Likewise, and don't call m4_exit in
2069 b4_use_push_for_pull_if or m4_wrap code will never execute.
2070 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
2072 (muscle_grow_user_name_list): ... this for consistency with the
2073 terminology used in bison.m4.
2074 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
2075 %define variable names, and rename muscle used_percent_define_variables
2076 to user_percent_define_variables.
2077 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
2078 user_percent_code_qualifiers.
2080 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
2081 {CODE} form is no longer accepted.
2082 * tests/input.at (Reject bad %code qualifiers): Rename to...
2083 (Reject unused %code qualifiers): ... this, and update test output.
2084 (%define error): Update test output.
2086 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
2088 Check for unrecognized %define variables similar to checking for
2089 unrecognized %code qualifiers. Check for redefined %define variables.
2090 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
2092 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
2093 (b4_check_percent_define_variables): New, also wraps it.
2094 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
2095 variables using b4_check_percent_define_variables.
2096 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
2097 all those exercised in the test suite and all those listed in the
2098 `Default values' section of c++.m4. Are there others?
2099 * data/push.c, data/yacc.c: Declare no valid %define variables.
2100 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
2101 similar to muscle_find, but it works even when the muscle stores a
2103 (muscle_grow_used_name_list): New function for constructing the used
2104 name list muscles that b4_check_for_unrecognized_names requires.
2105 * src/parse-gram.y (prologue_declaration): Warn if a variable is
2106 %define'd more than once. Define the b4_used_percent_define_variables
2107 muscle with muscle_grow_used_name_list.
2108 (grammar_declaration): Abbreviate %code code with
2109 muscle_grow_used_name_list.
2110 * tests/input.at (%define errors): New.
2112 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2114 Provide warn_at, complain_at, and fatal_at function callbacks to the
2115 skeletons, and use this for %code qualifier complaints.
2116 * data/bison.m4 (b4_error_at): New, invoked by...
2117 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
2118 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
2119 @fatal_at(...@) directives.
2120 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
2121 qualifiers in b4_used_percent_code_qualifiers and to use
2123 * src/location.c, src/location.h (boundary_set_from_string): New global
2125 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
2127 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
2128 to b4_used_percent_code_qualifiers.
2129 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
2131 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
2132 (lineno): Rename to...
2133 (out_lineno): ... this so I don't misunderstand it again.
2134 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
2135 here; these newlines are in the input but not the output file.
2136 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
2137 (at_directive_perform): ... this new static function, and add handling
2138 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
2140 * tests/input.at (Reject bad %code qualifiers): Update test output with
2141 locations and extend.
2143 * tests/output.at (Output file name: [, Output file name: ]): Remove
2144 bogus comment about these tests failing.
2146 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2148 Clean up b4_check_percent_code_qualifiers a little.
2149 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
2150 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
2151 documentation and add examples.
2152 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
2155 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2157 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
2158 unreliable -- especially when they're hidden inside another macro.
2159 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
2160 data/c.m4: Remove m4_divert(-1).
2161 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2162 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
2163 m4_divert_push(0) and m4_divert_pop(0).
2164 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
2165 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
2166 pushed and popped by m4sugar, should be first on the stack.
2168 Provide warn, complain, and fatal function callbacks to the skeletons.
2169 This provides more flexibility than m4_fatal, improves the error
2170 message format, and captures messages for translation. Discussed
2172 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
2173 * data/bison.m4 (b4_error): New, invoked by...
2174 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
2175 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
2176 directives. Because these M4 macros might be called when the current
2177 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
2178 the previous removal of uses of m4_divert, which caused trouble.
2179 (b4_check_percent_code_qualifiers): Use b4_complain instead of
2180 m4_fatal to report unrecognized %code qualifiers.
2181 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
2182 push parser requests.
2183 * data/glr.c: Use b4_complain instead of m4_fatal to report
2184 non-deterministic push parser requests.
2185 Update @output usage to @output(...@) form.
2186 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
2187 report missing %defines. Update @output usage to @output(...@) form.
2188 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
2190 * src/main.c (main): Invoke skel_scanner_free.
2191 * src/scan-skel.h (skel_scanner_free): Prototype new function.
2192 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
2193 obstack_for_string from flex-scanner.h.
2194 (YY_DECL): Use to declare skel_lex static.
2195 (decode_at_digraphs): Remove; now handled in the new
2196 SC_AT_DIRECTIVE_ARG start condition.
2197 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
2199 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
2200 at_directive_argv): New static globals.
2201 (INITIAL): Use fail_for_invalid_at.
2202 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
2203 recognize the start of a generalized `@directive(...@)' form and
2205 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
2206 directive args (using the new obstack_for_string), to decode the
2207 contained @ diagraphs, and to perform the directive. It recognizes
2208 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
2210 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
2211 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
2213 (scan_skel): Initialize obstack_for_string on the first call.
2214 (skel_scanner_free): New function to free obstack_for_string.
2215 * tests/input.at (Reject bad %code qualifiers): Update test output.
2217 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
2219 Consolidate the 4 prologue alternative directives (%code, %requires,
2220 %provides, and %code-top) into a single %code directive with an
2221 optional qualifier field. Discussed at
2222 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
2223 * NEWS (2.3a+): Rewrite the existing entry for the prologue
2225 * doc/bison.texinfo (Prologue Alternatives): Update.
2226 (Decl Summary): Update to %code "requires" and %code "provides".
2227 (Calc++ Parser): Update to %code "requires".
2228 (Table of Symbols): Remove entries for %requires, %provides, and
2229 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
2230 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
2231 are replaced by b4_percent_code_provides and b4_percent_code_requires,
2232 which are skeleton-specific.
2233 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
2234 declare what %code qualifiers it supports and to complain if any other
2235 qualifiers were used in the grammar.
2236 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
2237 and b4_user_code([b4_percent_code_provides]) in place of
2238 b4_user_requires and b4_user_provides.
2239 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
2240 Add b4_user_code([b4_percent_code_top]) and
2241 b4_user_code([b4_percent_code]).
2242 Invoke b4_check_percent_code_qualifiers.
2243 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2244 PERCENT_REQUIRES): Remove.
2245 (grammar_declaration): Remove RHS's for %code-top, %provides, and
2246 %requires. Rewrite the %code RHS as the unqualified form defining the
2247 muscle b4_percent_code. Add another RHS for the qualified %code form,
2248 which defines muscles of the form b4_percent_code_QUALIFIER and the
2249 b4_used_percent_code_qualifiers muscle.
2250 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2251 PERCENT_REQUIRES): Remove.
2252 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
2253 %code "requires" and %code "provides".
2254 * tests/input.at (Reject bad %code qualifiers): New.
2256 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2258 Use the new code_props interface for destructors and printers.
2259 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
2260 printer_location members, and change the type of the destructor and
2261 printer members to code_props.
2262 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
2263 symbol_printer_get, semantic_type_destructor_set,
2264 semantic_type_printer_set, default_tagged_destructor_set,
2265 default_tagless_destructor_set, default_tagged_printer_set,
2266 default_tagless_printer_set): Use code_props in arguments and return
2267 types in place of char const * and location.
2268 (symbol_destructor_location_get, symbol_printer_location_get): Remove
2269 since the locations are now contained in the return of
2270 symbol_destructor_get and symbol_printer_get.
2271 * src/output.c (symbol_destructors_output, symbol_printers_output):
2273 (symbol_code_props_output): ... this to eliminate duplicate code.
2274 (output_skeleton): Update to use symbol_code_props_output.
2275 * src/reader.c (symbol_should_be_used): Update use of
2276 symbol_destructor_get.
2277 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
2278 Update uses of the various _destructor_set and _printer_set functions.
2279 * src/symtab.c: (default_tagged_destructor_location,
2280 default_tagless_destructor_location, default_tagged_printer_location,
2281 default_tagless_printer_location): Remove since we...
2282 (default_tagged_destructor, default_tagless_destructor,
2283 default_tagged_printer, default_tagless_printer): ... change the type
2284 of these to code_props.
2285 (symbol_new, semantic_type_new, symbol_destructor_set,
2286 semantic_type_destructor_set, symbol_destructor_get,
2287 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
2288 symbol_check_alias_consistency, default_tagged_destructor_set,
2289 default_tagless_destructor_set, default_tagged_printer_set,
2290 default_tagless_printer_set): Update.
2291 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
2292 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
2294 (symbol_print): Use SYMBOL_CODE_PRINT.
2296 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2298 Use the new code_props interface for rule actions.
2299 * src/symlist.h (symbol_list): Replace action, action_location, and
2300 used members with a code_props action_props member.
2301 * src/reader.c (symbol_should_be_used, grammar_rule_check,
2302 grammar_midrule_action, grammar_current_rule_merge_set,
2303 grammar_current_rule_symbol_append, packgram): Update.
2304 * src/scan-code.h (translate_rule_action): Remove, no longer used.
2305 * src/scan-code.l (handle_action_dollar): Update.
2306 (translate_rule_action): Remove, no longer used.
2307 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
2309 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2311 Use the new code_props interface in parse-gram.y.
2312 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
2313 Update all uses of translate_* functions to use the new code_props
2314 interface and to use gram_scanner_last_string_free and
2315 code_scanner_last_string_free where possible.
2316 (grammar_declaration): symbol_list_destructor_set and
2317 symbol_list_printer_set now perform the translation, so don't do it
2318 here. Use gram_scanner_last_string_free where possible.
2319 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
2320 translate_code): Remove, no longer used.
2321 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
2322 symbol_list_printer_set): Perform code translation here rather than
2323 depending on the caller to do so.
2325 * src/symlist.h (struct symbol_list): Correct some documentation typos.
2326 * src/scan-gram.h (gram_last_string): Remove declaration.
2327 * src/scan-gram.l (last_string): Declare it static.
2329 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2331 Encapsulate code properties and related functionality for the various
2332 destructors, printers, and actions into a code_props structure and
2333 interface. This patch merely implements code_props in scan-code.h and
2334 scan-code.l. Future patches will rewrite other modules to use it.
2335 Discussed starting at
2336 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
2337 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
2338 consistently initialize const structs that have an empty location
2340 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
2341 to ensure consistency.
2342 * src/scan-code.h (code_props): New structure.
2343 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
2344 function, macro, and const global variable for initializing a
2345 code_props with no code.
2346 (code_props_plain_init, code_props_symbol_action_init,
2347 code_props_rule_action_init, code_props_translate_code): The rest of
2348 the new code_props functional interface. Among other things, the init
2349 functions set the code_props kind field so that
2350 code_props_translate_code will know whether to behave like
2351 translate_symbol_action, translate_rule_action, or translate_code.
2352 These old translate functions must remain until all other modules are
2353 updated to use the new code_props interface.
2354 (code_scanner_last_string_free): New function similar to
2355 gram_scanner_last_string_free.
2356 (code_scanner_free): Add documentation.
2357 * src/scan-code.l: Implement the new interface.
2358 (code_lex): Make it static, add a code_props* argument, and remove the
2360 (last_string): New static global similar to the one in scan-gram.l.
2361 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
2363 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
2364 code_props since Bison may one day use this information for destructors
2366 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
2367 (handle_action_dollar): Use symbol_list_n_get and set used flag
2368 directly since symbol_list_n_used_set is removed.
2369 (translate_action): Add a code_props* argument and remove the rule,
2370 action, and location arguments. Pass the code_props* on to code_lex.
2371 (translate_rule_action, translate_symbol_action, translate_code):
2372 Rewrite as wrappers around the new code_props interface.
2373 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
2374 it would eventually need to break the encapsulation of code_props.
2376 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
2378 * etc/.cvsignore: New.
2380 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
2382 Add maintainer-push-check to run maintainer-check using push parsing in
2383 place of pull parsing where available.
2384 * Makefile.am (maintainer-push-check): New.
2385 * data/bison.m4 (b4_use_push_for_pull_if): New.
2386 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
2387 appropriately based on their existing values.
2388 (yypush_parse): Don't print push-parser-specific diagnostics if push
2389 parsing is being used in place of pull parsing.
2390 * data/yacc.c: If push parsing should replace pull parsing, redirect to
2392 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
2393 variable, and insert b4_use_push_for_pull_flag into muscles.
2394 * tests/Makefile.am (maintainer-push-check): New.
2396 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2398 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
2399 (whether successful or failed) so that yypush_parse can be invoked
2400 again to start a new parse using the same yypstate.
2401 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
2402 check multiple yypull_parse invocations on the same yypstate. For pull
2403 mode, extend to check multiple yyparse invocations.
2404 (Exploding the Stack Size with Alloca): Extend to try with
2406 (Exploding the Stack Size with Malloc): Likewise.
2408 * tests/calc.at (Simple LALR Calculator): Don't specify
2409 %skeleton "push.c" since %push-pull-parser implies that now.
2410 * tests/headers.at (export YYLTYPE): Don't check for the push
2411 declarations. Otherwise, this test case can't be used to see if push
2412 mode can truly emulate pull mode.
2413 * tests/input.at (Torturing the Scanner): Likewise.
2414 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
2415 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
2416 AT_YACC_IF, which now includes the case of push mode since %skeleton
2417 need not be used for push mode. This will be more intuitive once
2418 push.c is renamed to yacc.c.
2420 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2422 For push mode, convert yyparse from a macro to a function, invoke yylex
2423 instead of passing a yylexp argument to yypull_parse, and don't
2424 generate yypull_parse or yyparse unless %push-pull-parser is declared.
2425 Discussed starting at
2426 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
2427 * data/bison.m4 (b4_pull_if): New.
2428 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
2429 * data/push.c: Improve M4 quoting a little.
2430 (b4_generate_macro_args, b4_parenthesize): Remove.
2431 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
2432 any time a pull parser is requested.
2433 Don't #define this as a wrapper around yypull_parse. Instead, when
2434 both push and pull are requested, make it a function that does that
2436 (yypull_parse): If there's a b4_prefix, #define this to
2437 b4_prefix[pull_parse] when both push and pull are requested.
2438 Don't define this as a function unless both push and pull are
2440 Remove the yylexp argument and hard-code yylex invocation instead.
2441 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
2443 * src/getargs.c (pull_parser): New global initialized to true.
2444 * getargs.h (pull_parser): extern it.
2445 * src/output.c (prepare): Insert pull_flag muscle.
2446 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
2447 (prologue_declaration): Set both push_parser and pull_parser = true for
2448 %push-pull-parser. Set push_parser = true and pull_parser = false for
2450 * src/scan-gram.l: Don't accept %push_parser as an alternative to
2451 %push-parser since there's no backward-compatibility concern here.
2452 Scan %push-pull-parser.
2453 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
2454 instead of %push-parser.
2455 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
2456 prototype it in the module that calls yyparse.
2457 * tests/input.at (Torturing the Scanner): Likewise.
2458 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
2460 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
2462 Update etc/bench.pl. Optimize push mode a little (the yyn change
2463 deserves most of the credit).
2464 * Makefile.am (SUBDIRS): Add etc subdirectory.
2465 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
2466 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
2467 yytoken, yyval, and yyloc declarations to...
2468 (yyparse or yypush_parse): ... here to improve performance. For
2469 yypush_parse invocations after the first, be sure to assign yyn its old
2471 (yypstate_new): Don't bother initializing the yyresult field since the
2472 initial value isn't used.
2473 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
2474 remove the #define that, in push mode, set it to yyps->NAME.
2475 * etc/Makefile.am: New.
2476 * etc/bench.pl: Remove and build it instead from...
2477 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
2478 "tests/bison" from the build directory by default rather than just
2479 invoking "bison" from $PATH.
2480 (calc_grammar): Update push parser code: don't declare yylval globally,
2481 don't define yyparse_wrapper, and don't #define yyparse.
2482 (bench_grammar): Update to check all working combinations of yacc.c,
2483 push.c, impure, pure, pull, and push.
2485 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2487 For push mode, add pull wrappers around yypush_parse.
2488 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
2489 (yypull_parse): New function wrapping yypush_parse.
2490 (yyparse): New #define wrapping yypull_parse.
2491 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
2493 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
2494 prototype yylex in the module that calls yyparse, and don't prototype
2495 yyparse there. Otherwise, the yyparse expansion won't compile.
2496 * tests/input.at (Torturing the Scanner): Likewise.
2498 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2500 Enable push parsers to operate in impure mode. Thus, %push-parser no
2501 longer implies %pure-parser. The point of this change is to move
2502 towards being able to test the push parser code by running the entire
2503 test suite as if %push-parser had been declared.
2504 * data/push.c (yypush_parse): For impure mode, remove the
2505 yypushed_char, yypushed_val, and yypushed_loc arguments.
2506 Instead, declare these as local variables initialized to the global
2507 yychar, yylval, and yylloc.
2508 For the first yypush_parse invocation only, restore the initial values
2509 of these global variables when it's time to read a token since they
2510 have been overwritten.
2511 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
2513 * tests/calc.at (Simple LALR(1) Calculator): Always declare
2514 %pure-parser along with %push-parser since this test case was designed
2515 for pure push parsers.
2516 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
2517 (AT_YACC_OR_PUSH_IF): New.
2518 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
2519 add a note that it's still wrong for some cases (as it has been for a
2521 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
2522 %push-parser no longer implies %pure-parser.
2524 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2526 Remove some unnecessary differences between the pull parser code and
2527 the push parser code. This patch enables yynerrs in push mode.
2528 * data/push.c: Reformat M4 a little.
2529 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
2530 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
2531 because push mode is on. Instead, if pure mode is on, move yynerrs
2533 (b4_declare_parser_state_variables): ... here.
2534 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
2535 to yyps->NAME so it can be used in yypush_parse.
2536 (yypush_parse): Don't omit uses of yynerrs in push mode.
2538 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2540 Fix bug such that the first pushed token's value and location are
2541 sometimes overwritten (sometimes by %initial-action) before being used.
2542 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
2543 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
2544 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
2545 more closely mimic the pull parser logic.
2546 Don't copy the pushed token to yychar, yylval, and yylloc until it's
2547 time to read a token, which is after any initialization of yylval and
2549 (gottoken): Rename label to...
2550 (yyread_pushed_token): ... for clarity and to avoid infringing on the
2553 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2555 Rearrange initialization of the parser state variables so that the
2556 skeleton doesn't have to have a copy for pull mode and another for push
2557 mode. This patch also fixes at least a bug such that yylloc was not
2558 initialized (with b4_location_initial_line and
2559 b4_location_initial_column) upon calling yypush_parse. However, that
2560 initialization now overwrites the first token's location;
2561 %initial-action assigning @$ already did the same thing, and both bugs
2562 will be fixed in a later patch.
2563 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
2564 (b4_declare_parser_state_variables): Remove initialization of yytoken,
2565 yyss, yyvs, yyls, and yystacksize.
2566 (yypstate_new): Remove initialization of some yypstate fields: yystate,
2567 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
2569 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
2570 yyps->NAME so it can be used in yypush_parse.
2571 (yyparse or yypush_parse): For yypush_parse, don't print the
2572 "Starting parse" diagnostic for invocations after the first.
2573 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
2574 yypush_parse, only do it for the first invocation.
2575 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
2576 initialization to occur in yypush_parse but only on the first
2579 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2581 * data/push.c: Add CPP guards around push parser declarations in both
2582 the header and the code file.
2583 In the code file, move the push parser declarations to the same place
2584 they appear in the header file.
2585 Clean up the M4 some, especially the inconsistent underquoting in
2586 some b4_c_function_def and b4_c_function_decl uses.
2588 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2590 Encapsulate the push parser state variables into an M4 macro so the
2591 push skeleton doesn't have to list them again for pull mode's yyparse.
2592 For push mode, remove yypush_parse's local equivalents of these
2593 variables to eliminate unnecessary copying between the two sets at
2594 run-time. This patch also fixes at least a bug related to multiple
2595 %initial-action invocations in push mode.
2596 * data/push.c (b4_declare_parser_variables): Rename to...
2597 (b4_declare_scanner_communication_variables): ... this for clarity and
2599 (b4_declare_yyparse_variables): Remove and move its contents to the one
2600 spot where it was invoked.
2601 (b4_declare_parser_state_variables): New macro containing the parser
2602 state variables required by push mode.
2603 (struct yypstate): Replace all fields but yynew with
2604 b4_declare_parser_state_variables.
2605 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
2606 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
2607 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
2608 (yyparse or yypush_parse): For yyparse in pull mode, replace local
2609 parser state variable declarations with
2610 b4_declare_parser_state_variables.
2611 Don't initialize parser state variables when calling yypush_parse since
2612 yypstate_new already does that.
2613 Invoke the user's initial action only upon the first yypush_parse
2615 Remove all code that copies between the local parser state variables
2618 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2620 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
2621 prevent a name collision in a future patch where these names will
2622 sometimes be #define'd.
2623 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
2624 since it no longer has the same name as the existing argument.
2625 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
2627 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
2628 and Joel E. Denny <jdenny@ces.clemson.edu>
2630 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
2631 that the argument is case-insensitive, and there's no `=' here.
2632 For the %skeleton entry, mention that %language is better.
2633 (Bison Options): Likewise for --language and --skeleton. Move the
2634 --skeleton entry so that the `Tuning the parser' section is sorted
2635 alphabetically on long options.
2636 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
2637 %language directive in detail here; cross-reference the %language
2638 documentation instead.
2639 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
2640 `%require "2.3b"' so that the example is always up-to-date.
2641 (Table of Symbols): Add entries for %language and %skeleton.
2642 * examples/extexi (normalize): Instead of replacing every %require
2643 argument with the current Bison version, just substitute for
2644 `@value{VERSION}'. This guarantees that we're testing what actually
2645 appears in the documentation.
2646 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
2647 rather than `@VERSION@'.
2649 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2651 * NEWS: Reword the %language news a bit, and put it earlier.
2653 * src/getargs.c (skeleton_arg): Last arg is now location const *.
2654 Rewrite to simplify the logic.
2655 (language_argmatch): Likewise.
2656 (program_name): We now own this var.
2657 * src/getargs.h (struct bison_language): Use char[] rather than
2660 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
2662 * src/complain.c (program_name): Remove decl; no longer needed.
2663 * src/main.c (program_name): Remove; now belongs to getargs.
2665 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
2667 * NEWS: Document %language.
2669 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
2671 * data/c-skel.m4, data/c++-skel.m4: New files.
2672 * data/glr.c: Complain on push parsers.
2674 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
2676 (Decl Summary): Document %language and %skeleton.
2677 (Command line): Document -L.
2679 * examples/extexi: Rewrite %require directive.
2680 * examples/calc++/Makefile.am: Pass VERSION to extexi.
2682 * src/files.c (compute_exts_from_gc): Look in language structure
2684 (compute_file_name_parts): Check whether .tab should be added.
2685 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
2686 (language, skeleton_arg, language_argmatch): New.
2687 (long_options): Add --language.
2688 (getargs): Use skeleton_arg, add -L/--language.
2689 * src/getargs.h: Include location.h.
2690 (struct bison_language, language, skeleton_arg, language_argmatch): New.
2691 * src/output.c (prepare): Pick default skeleton from struct language.
2692 Don't dispatch C skeletons here.
2693 * src/parse-gram.y (PERCENT_LANGUAGE): New.
2694 (prologue_declaration): Add "%language" rule, use skeleton_arg.
2695 * src/scan-gram.l ("%language"): New rule.
2697 * tests/calc.at: Test %skeleton and %language.
2698 * tests/local.at (AT_SKEL_CC_IF): Look for %language.

2700 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
2701 (AT_YACC_IF): Reject %language.
2703 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2705 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
2706 since it wasn't used; only the typedef name 'semantic_type' is needed.
2707 Also, omit trailing white space.
2709 * bootstrap: Sync from coreutils.
2710 (gnulib_extra_files): Add build-aux/announce.gen.
2711 (slurp): Adjust .gitignore files like .cvsignore files.
2712 * build-aux/announce-gen: Remove from CVS, since bootstrap
2715 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
2717 Make %push-parser imply %pure-parser. This fixes several bugs; see
2718 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
2719 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
2721 * data/push.c: Don't bother testing b4_push_if when deciding whether
2722 to expand b4_declare_parser_variables globally.
2723 (yypush_parse): Likewise in here.
2725 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
2726 (yy_reduce_print): Reformat M4 for readability.
2728 2006-12-15 Bob Rossi <bob@brasko.net>
2729 and Joel Denny <jdenny@ces.clemson.edu>
2731 * data/push.c (yypstate): Add typedef, and update all uses of
2732 struct yypstate to just yypstate.
2733 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
2735 2006-12-14 Bob Rossi <bob@brasko.net>
2737 * data/push.c (yypush_parse): Declare prototype regardless of
2740 2006-12-14 Bob Rossi <bob@brasko.net>
2742 * data/push.c (yyparse): Remove the prototype and the #define when in
2745 2006-12-13 Bob Rossi <bob@brasko.net>
2747 * data/push.c (yypstate_init): Rename to...
2748 (yypstate_new): ... this and use b4_c_function_def.
2749 (yypstate_delete): New.
2750 (yypush_parse): Change parameters yynval and yynlloc to be const.
2751 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
2752 yypstate_delete functions.
2754 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
2756 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
2757 strange test case titles. Reported by Bob Rossi.
2759 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
2761 * TODO: Add pointer to Sylvain Schmitz's work on static detection
2762 of potential ambiguities in GLR grammers.
2764 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
2766 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
2767 `bison ', use m4_index instead of m4_substr since chopping up a string
2768 containing M4-special characters causes problems here.
2770 Fix a couple of bugs related to special characters in user-specified
2771 file names, and make it easier for skeletons to compute output file
2772 names with the same file name prefix as Bison-computed output file
2774 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
2775 b4_parser_file_name and b4_spec_defines_file instead of
2776 @output_parser_name@ and @output_header_name@, which are now redundant.
2777 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
2778 b4_parser_file_name, b4_spec_defines_file, and the new
2779 @basename(FILENAME@) instead of @output_parser_name@ and
2780 @output_header_name@, which inappropriately escaped the file names as
2782 * src/files.c (all_but_ext): Remove static qualifier.
2783 (compute_output_file_names): Move `free (all_but_ext)' to...
2784 (output_file_names_free): ... here since all_but_ext is needed later.
2785 * src/files.h (all_but_ext): Extern.
2786 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
2787 exactly what MUSCLE_INSERT_STRING used to do.
2788 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
2789 characters are escaped properly.
2790 * src/output.c (prepare): Define muscle file_name_all_but_ext as
2792 For pkgdatadir muscle, maintain previous functionality by using
2793 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
2794 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
2795 digraphs would never be expanded. Hopefully no one has M4-special
2796 characters in his Bison installation path.
2797 * src/scan-skel.l: Don't parse @output_header_name@ and
2798 @output_parser_name@ anymore since they're now redundant.
2799 In @output, use decode_at_digraphs.
2800 Parse a new @basename command that invokes last_component.
2801 (decode_at_digraphs): New.
2802 (BASE_QPUTS): Remove unused.
2803 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
2804 (Output file name): New tests.
2806 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
2808 Warn about output files that are generated by the skeletons and that
2809 conflict with other output files.
2810 * data/glr.c: Don't generate the header file here when glr.cc does.
2811 * src/files.c (file_names, file_names_count): New static globals.
2812 (compute_output_file_names): Invoke output_file_name_check for files
2813 not generated by the skeletons and remove existing checks.
2814 (output_file_name_check): New function that warns about conflicting
2816 (output_file_names_free): Free file_names.
2817 * src/files.h (output_file_name_check): Declare.
2818 * src/scan-skel.l: Invoke output_file_name_check for files generated by
2820 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
2821 (Conflicting output files): New tests.
2823 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2825 * doc/bison.texinfo: Fix a couple of typos.
2827 2006-12-08 Bob Rossi <bob@brasko.net>
2829 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
2831 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
2833 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
2834 (yypush_parse): Rename yypvars argument to yyps and remove redundant
2836 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
2837 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
2839 2006-12-07 Bob Rossi <bob@brasko.net>
2840 and Joel Denny <jdenny@ces.clemson.edu>
2842 * data/push.c (yypvarsinit): Change return type from void* to struct
2843 yypvars*. No longer cast to void* on return.
2844 (struct yypvars): Remove yylen since it need not be remembered between
2845 yypushparse invocations.
2846 (yypushparse): Don't copy between yylen and pv->yylen.
2848 2006-12-05 Bob Rossi <bob@brasko.net>
2850 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
2851 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
2852 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
2853 (struct yypvars): Remove b4_declare_parser_variables.
2854 (yypvarsinit): Remove init code for removed variables.
2855 (global scope): Do not declare b4_declare_parser_variables if
2857 (yypushparse): Add b4_declare_parser_variables.
2858 Init new local variables, and remove init code for removed
2861 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
2862 and yyparse for other modes.
2863 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
2864 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
2865 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
2866 (AT_PURE_LEX_IF): True if pure or push parser.
2868 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
2870 Document Yacc prologue alternatives and default %destructor's and
2871 %printer's as experimental. Don't mention Java yet. Discussed at

2895 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
2896 occurrence of each of %file-prefix and %output. Add check for %defines
2898 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
2899 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
2900 Remove the `=' from %output.
2902 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
2904 Don't escape $ in test case titles since Autoconf 2.61 now does that

2923 * tests/actions.at (Default tagless %printer and %destructor,
2924 Default tagged and per-type %printer and %destructor,
2925 Default %printer and %destructor are not for error or $undefined,
2926 Default %printer and %destructor are not for $accept,
2927 Default %printer and %destructor for mid-rule values): Update.
2928 * tests/input.at (Default %printer and %destructor redeclared,
2929 Unused values with default %destructor): Update.

2944 grammar is maintained with Bison's highest standards.
2945 * src/getargs.c: Fix some typos in Doxygen comments.
2947 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
2949 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
2950 later. Reported by Paul Eggert in
2951 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
2952 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
2953 * src/scan-code.l (translate_action): Don't bother invoking
2954 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
2955 (code_scanner_free): Instead of invoking
2956 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

2964 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
2965 has been called previously for the same key.
2966 (muscle_find): Return storage instead of value so that
2967 --enable-gcc-warnings doesn't produce warnings that the return discards
2968 const. aver that the value and storage are the same since storage
2969 could potentially be NULL when value is not.
2970 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the

2975 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
2976 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives

2987 since they are freed.
2988 * src/files.c: Likewise.

2991 (tr): Now operates in-place. All uses changed.

2995 read-only data in variables that will be freed.
2996 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
2997 src_extension, and header_extension.

2999 spec_verbose_file, spec_graph_file, spec_defines_file,
3000 parser_file_name, and dir_prefix.
3001 * src/getargs.c (getargs): Don't store read-only data in variables that
3003 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
3004 (which previously existed but was unused), and quotearg_free.
3005 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
3006 * src/muscle_tab.c: Likewise.
3007 (muscle_entry): Make the value char const *,
3008 and add a new storage member that is char * and can be freed.
3009 (muscle_entry_free): New private function.
3010 (muscle_init): Use it instead of free.
3011 (muscle_insert, muscle_grow): Update and use new storage member.
3012 (muscle_code_grow): Free the string passed to muscle_grow
3013 since it's not needed anymore.
3014 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
3015 add a new `char *code' member.
3016 ("{...}"): Declare semantic type as code.
3017 * src/scan-code.h (translate_rule_action):
3018 (translate_symbol_action, translate_code, translate_action): Return
3019 `char const *' rather than `char *' since external code should not free
3021 * src/scan-code.l: Likewise.
3022 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
3023 which is "{...}" in the parser.
3024 * tests/Makefile.am (maintainer-check-valgrind): Set
3025 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
3027 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
3029 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
3030 expecting a non-zero exit status sets --leak-check=summary and
3031 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
3032 this case, and we don't want to hear about it.

3053 declarations): Run tests with and without --warnings=midrule-values.
3055 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
3056 than LIST_FREE directly.
3058 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

3077 empty subargument list. For example: `bison --warnings= parser.y'.
3079 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3081 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
3082 the parser header file so that gcc doesn't warn.
3084 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

3132 Don't apply the default %destructor/%printer to an unreferenced midrule
3134 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
3135 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
3136 like $@n instead of just @n so that the default %destructor/%printer
3137 logic doesn't see them as user-defined symbols.
3138 (symbol_is_dummy): Check for both forms of the name.
3139 * src/reader.c (packgram): Remove the `$' from each midrule symbol
3140 name for which the midrule value is referenced in any action.
3141 * tests/actions.at (Default %printer and %destructor for mid-rule
3143 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
3144 for change to dummy symbol names.
3146 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
3148 Warn about unset midrule $$ if the corresponding $n is used.
3149 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
3151 (packgram): Before invoking grammar_rule_check on any rule, make sure
3152 all actions have already been scanned in order to set `used' flags.
3153 Otherwise, checking that a midrule's $$ is set will not always work
3154 properly because the midrule check must forward-reference the midrule's
3156 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
3159 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
3161 More improvements to the documentation of the prologue alternatives:
3162 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
3164 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
3165 some text to clarify the relative importance of the new directives and
3166 to show how these directives may be viewed as code labels.
3168 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
3170 Similar to the recently removed %before-header, add %code-top as the
3171 alternative to the pre-prologue. Mentioned at
3172 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
3173 Also, let the prologue alternatives appear in the grammar section.
3174 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
3175 (prologue_declaration): Move the existing prologue alternatives to...
3176 (grammar_declaration): ... here and add %code-top.

3183 (Prologue Alternatives): ... this new section, and extend it to discuss
3184 all 4 directives in detail.
3185 (Table of Symbols): Clean up discussion of prologue alternatives and
3188 2006-10-16 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3190 DJGPP specific issues.

3195 * djgpp/config.site: Likewise.
3197 2006-10-16 Paolo Bonzini <bonzini@gnu.org>

3223 2006-10-14 Jim Meyering <jim@meyering.net>
3225 (Sync from coreutils.)
3226 Work also when the working directory (with e.g. coreutils sources)
3227 is version controlled with git, rather than CVS.
3228 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
3230 In messages and comments, say e.g., "checked-out sources",
3231 rather than "CVS sources".
3232 (version_controlled_file): New function. Work for git as well as
3233 for CVS. Don't use grep's -q option.
3234 (slurp): Call it here, in place of CVS-specific code.
3236 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
3238 Fix testsuite for ./configure --enable-gcc-warnings:
3239 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
3240 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
3241 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
3242 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.

3281 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3283 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
3284 variable was sometimes used without being initialized. This
3285 messed up the installation of the INSTALL file in some cases.
3287 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
3289 * bootstrap (usage, main program, symlink_to_gnulib): Add option
3290 --copy. Inspired by a suggestion from Bruno Haible.
3292 2006-10-03 Jim Meyering <jim@meyering.net>
3294 * bootstrap: Undo last change to this file, since now gnulib-tool
3295 sticks with the automake default in generating dependencies.
3297 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3299 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
3300 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
3302 * doc/bison.1: Add copyright notice.

3308 * doc/bison.1: Likewise.
3309 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
3310 * THANKS: Add Satya Kiran Popuri, who proposed the initial version

3323 * src/print_graph.c: Include graphviz.h rather than vcg.h.
3324 (static_graph, fgraph): Remove. All uses changed to pass
3325 arguments instead of sharing a static var.
3326 (print_core, print_actions, print_state, print_graph):
3327 Output graphviz format rather than VCG format.
3328 * tests/.cvsignore: Remove *.vcg; add *.dot.
3329 * tests/output.at: Expect *.dot files, not *.vcg files.

3332 accommodates the 2006-10-08 change.
3334 2006-10-11 Bob Rossi <bob@brasko.net>
3336 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.

3344 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
3345 in a push parser. Reindent slightly to match yacc.c better.
3347 2006-10-11 Bob Rossi <bob@brasko.net>

3361 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
3362 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
3363 b4_define_user_cde and uses): Remove.
3364 (b4_comment, b4_prefix, b4_sync_start): New.
3365 * data/bison.m4: New file, with most of the content removed from c.m4.
3366 * src/muscle_tab.h: Use "do {...} while(0)" throughout.

3373 Fix test failure reported by Tom Lane in
3374 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
3375 and try to make such failures easier to catch in the future.
3376 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
3377 that's now the caller's responsibility.
3378 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
3379 Set yychar = YYEOF if it's negative.
3380 * tests/actions.at (yylex): Abort if asked to read past EOF.

3388 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
3390 Fix problems with translating English-language diagnostics.
3391 * bootstrap: Fix bug introduced in recent bootstrap changes, with
3392 respect to bison-runtime pot generation. The YY_ stuff
3393 wasn't being captured.
3394 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
3395 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
3396 * runtime-po/POTFILES.in: Add data/push.c.
3398 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
3400 Merge bootstrap changes from coreutils.
3402 2006-09-28 Jim Meyering <jim@meyering.net>
3404 Automatically generated dependencies are important even
3405 when all of the sources in a directory come from gnulib.
3406 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
3407 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
3409 2006-09-23 Jim Meyering <jim@meyering.net>
3411 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
3413 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>

3427 * data/push.c (yyresult_get): Remove function.
3428 (YYPUSH_MORE): Add #define.
3429 (yypushparse): Modify return value.
3431 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
3433 * stamp-h.in: Remove; no longer needed.
3434 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
3435 Remove config.h, config.hin, intl (no longer created).
3436 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
3439 Sync bootstrap from coreutils, as follows:
3441 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
3443 * bootstrap (symlink_to_gnulib): New function.
3444 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
3445 to copies-of-gnulib.
3446 (cp_mark_as_generated, slurp, gnulib_files):
3447 Avoid making a copy if it's the same as the old version.
3448 (gnulib_files): Add support for this variable (used by Bison).
3450 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
3452 * src/getargs.c (usage): Rework to use conventions similar to
3453 coreutils, to make translation a bit easier and the code a bit
3454 smaller. Problem reported by Tim Van Holder.
3456 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
3458 Use some of gnulib's new modules, taken from coreutils.
3460 * bootstrap: Sync from coreutils, except add support for gnulib_files.
3461 * bootstrap.conf: New file.
3462 (gnulib_modules): Add configmake, inttypes, unistd.
3463 (XGETTEXT_OPTIONS): Add complain, complain_at,
3464 fatal, fatal_at, warn, warn_at, unexpected_end.
3465 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
3466 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
3468 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
3470 (GNULIB_AUTOCONF_SNIPPET): Remove.
3471 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
3473 * lib/.cvsignore: Add inttypes_.h.
3474 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
3475 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
3476 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
3477 no-longer-necessary initializations.
3478 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
3479 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
3480 use the unistd module.
3481 * src/system.h: Likewise.
3482 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,

3484 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
3485 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
3486 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
3487 * src/system.h: Include inttypes.h unconditionally, now that we
3488 use the inttypes module. Don't bother to include stdint.h, since
3489 inttypes.h now does that for us.
3490 (LOCALEDIR): Remove, now that we use the configmake module.
3491 * src/getargs.c: Include configmake.h.
3492 * src/main.c: Likewise.
3493 * src/output.c: Likewise.
3494 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
3495 not from $abs_top_builddir, since config.h moved.
3498 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
3499 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
3501 * src/parse-gram.y (symbol_declaration): Don't put statements
3502 before declarations; it's not portable to C89.
3503 * src/scan-code.l (handle_action_at): Likewise.
3505 * src/scan-code.l: Always initialize braces_level; the old code
3506 left it uninitialized and therefore had undefined behavior.
3508 Don't attempt to redefine 'assert', since it runs afoul of
3509 systems where standard headers (mistakenly) include <assert.h>.
3510 Instead, define and use our own alternative, called 'aver'.
3511 * src/reader.c: Don't include assert.h, since we no longer
3513 * src/scan-code.l: Likewise.
3514 * src/system.h (assert): Remove, replacing with....
3515 (aver): New function, taking a bool arg. All uses changed.
3516 * src/tables.c (pack_vector): Ensure that aver arg is bool,
3517 not merely an integer.
3519 2006-09-15 Bob Rossi <bob@brasko.net>
3521 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
3522 * data/c.m4 (YYPUSH): New.
3523 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
3524 * src/getargs.c (push_parser): New var.
3525 * src/getargs.h (push_parser): New declaration.
3526 * src/output.c (prepare): Add macro insertion of `push_flag'.
3527 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
3528 (prologue_declaration): Parse %push-parser.
3529 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
3530 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
3531 list of removed lines from the traces observed.
3532 (AT_CHECK_CALC_LALR): Added push parser tests.
3534 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
3536 * NEWS: Version 2.3a.
3537 * configure.ac (AC_INIT): Likewise.
3539 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
3540 "#define YYSTYPE int" that caused "make maintainer-check" to fail
3541 due to header ordering dependencies. I don't know why the #define
3544 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
3545 runtime cost when YYDEBUG is not defined, and so that some tests
3546 that used to fail now work. Problem and initial suggestion by
3548 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
3549 * data/glr.cc (b4_parser_class_name):
3550 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
3551 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
3552 (yydebug_) [YYDEBUG]: New member.
3553 (yycdebug_): Now defined only if YYDEBUG.
3554 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
3555 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
3556 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
3558 (debug_stream, set_debug_stream, debug_level, set_debug_level):
3559 Define only if YYDEBUG.
3560 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
3562 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
3563 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
3564 AT_CHECK_CALC_GLR_CC that are working now.
3566 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
3568 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
3569 We don't need them in glr.cc, and glr.c defines them.
3570 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
3571 assumes that defining it to anything is the same as defining
3572 it to 1. Problem reported by Paolo Bonzini.
3574 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
3576 * data/c.m4 (b4_null, b4_case): Define.
3577 * src/output.c (prepare_symbols): Use b4_null.
3578 (user_actions_output): Use b4_case.
3580 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
3582 * data/glr.c (b4_shared_declarations): Put start-header first,
3583 before any #includes that we generate, so that feature-test
3584 macros work. Problem reported by Michael Deutschmann in
3585 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
3586 * data/lalr1.cc: Likewise.
3587 * doc/bison.texinfo (Prologue): Document that feature-test macros
3588 should be defined before any Bison declarations.
3589 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
3590 that depend on location.hh after, not before, Bison decls, since
3591 we now include location.hh after the first user prologue.
3593 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
3594 Sander Brandenburg in
3595 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
3596 Also, fix minor white space and comment issues.
3597 (Prologue): Mention that it's better to define feature-test macros
3598 before Bison declarations. Problem reported by Michael Deutschmann.
3600 * README-cvs: Fix typo: "&" should be "&&". Problem reported
3602 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
3603 This adjusts to recent gnulib changes.
3605 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3607 Finish implementation of per-type %destructor/%printer. Discussed
3609 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
3611 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
3612 * NEWS (2.3+): Add a description of this feature to the default
3613 %destructor/%printer description.
3614 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
3615 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3616 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
3617 list node contains a semantic type.
3618 * src/symtab.c, src/symtab.h: Extend with a table that associates
3619 semantic types with their %destructor's and %printer's.
3620 (semantic_type_from_uniqstr, semantic_type_get,
3621 semantic_type_destructor_set, semantic_type_printer_set): New functions
3622 composing the public interface of that table.
3623 (symbol_destructor_get, symbol_destructor_location_get,
3624 symbol_printer_get, symbol_printer_location_get): If there's no
3625 per-symbol %destructor/%printer, look up the per-type before trying
3627 * tests/actions.at (Per-type %printer and %destructor): New test case.
3628 * tests/input.at (Default %printer and %destructor redeclared):
3629 Extend to check that multiple occurrences of %symbol-default in a
3630 single %destructor/%printer declaration is an error.
3631 (Per-type %printer and %destructor redeclared, Unused values with
3632 per-type %destructor): New test cases.
3634 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3636 Require default %destructor/%printer to be declared using
3637 %symbol-default instead of an empty symbol list, and start working on
3638 new per-type %destructor/%printer. Discussed at
3639 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
3640 * NEWS (2.3+): Add %symbol-default to example.
3641 * bison.texinfo (Freeing Discarded Symbols): Likewise.
3642 (Table of Symbols): Add entry for %symbol-default.
3643 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
3644 (generic_symlist, generic_symlist_item): New nonterminals for creating
3645 a list in which each item is a symbol, semantic type, or
3647 (grammar_declaration): Use generic_symlist in %destructor and %printer
3648 declarations instead of symbols.1 or an empty list.
3649 (symbol_declaration, precedence_declaration, symbols.1): Update actions
3650 for changes to symbol_list.
3651 * src/reader.c: Update for changes to symbol_list.
3652 * src/scan-code.l: Likewise.
3653 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
3654 * src/symlist.c, src/symlist.h: Extend such that a list node may
3655 represent a semantic type or a %symbol-default in addition to just an
3656 ordinary symbol. Add switched functions for setting %destructor's and
3658 * tests/actions.at, tests/input.at: Add %symbol-default to all default
3659 %destructor/%printer declarations.
3661 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
3663 Whether the default %destructor/%printer applies to a particular symbol
3664 isn't a question of whether the user *declares* that symbol (in %token,
3665 for example). It's a question of whether the user by any means
3666 *defines* the symbol at all (by simply using a char token, for
3667 example). $end is defined by Bison whereas any other token with token
3668 number 0 is defined by the user. The error token is always defined by
3669 Bison regardless of whether the user declares it with %token, but we
3670 may one day let the user define error as a nonterminal instead.
3671 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
3672 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
3673 the meaning of "user-defined".
3674 * tests/actions.at (Default %printer and %destructor for user-declared
3675 end token): Rename to...
3676 (Default %printer and %destructor for user-defined end token): ...
3679 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
3680 computation of whether to apply the default, don't maintain a list of
3681 every Bison-defined symbol. Instead, just check for a first character
3682 of '$', which a user symbol cannot have, and check for the error token.
3684 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
3686 Don't apply the default %destructor or %printer to the error token,
3687 $undefined, or $accept. This change fits the general rule that the
3688 default %destructor and %printer are only for user-declared symbols,
3689 and it solves several difficulties that are described in the new test
3691 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
3692 * tests/actions.at (Default %printer and %destructor are not for error
3693 or $undefined, Default %printer and %destructor are not for $accept):
3696 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
3698 Allow %start after the first rule.
3699 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
3700 when parsing the first rule.
3701 (check_and_convert_grammar): Search for it here after all grammar
3702 declarations have been parsed. Skip midrules, which have dummy LHS
3704 * src/symtab.c (symbol_is_dummy): New function.
3705 * src/symtab.h (symbol_is_dummy): Declare it.
3706 * tests/input.at (%start after first rule): New test.
3708 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3710 Redo some of the previous commit: add back the ability to use
3711 non-aliased/undeclared string literals since it might be useful to
3712 those declaring %token-table.
3713 * src/reader.c (check_and_convert_grammar): Undo changes in previous
3714 commit: don't worry about complaints from symbols_pack.
3715 * src/symtab.c (symbol_new, symbol_class_set,
3716 symbol_check_alias_consistency): Undo changes in previous commit: count
3717 each string literal as a new symbol and token, assign it a symbol
3718 number, and don't complain about non-aliased string literals.
3719 (symbols_pack): Since symbol_make_alias still does not decrement symbol
3720 and token counts but does still set aliased tokens to the same number,
3721 symbol_pack_processor now leaves empty slots in the symbols array.
3723 * tests/regression.at (Undeclared string literal): Remove test case
3724 added in previous commit since non-aliased string literals are allowed
3726 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
3727 remove unnecessary string literal declarations.
3728 * tests/sets.at (Firsts): Likewise.
3730 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3732 Don't allow an undeclared string literal, but allow a string literal to
3733 be used before its declaration.
3734 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
3735 symbols_pack complained.
3736 * src/symtab.c (symbol_new): Don't count a string literal as a new
3738 (symbol_class_set): Don't count a string literal as a new token, and
3739 don't assign it a symbol number since symbol_make_alias does that.
3740 (symbol_make_alias): It's not necessary to decrement the symbol and
3741 token counts anymore. Don't assume that an alias declaration occurs
3742 before any uses of the identifier or string, and thus don't assert that
3743 one of them has the highest symbol number so far.
3744 (symbol_check_alias_consistency): Complain if there's a string literal
3745 that wasn't declared as an alias.
3746 (symbols_pack): Bail if symbol_check_alias_consistency failed since
3747 symbol_pack asserts that every token has been assigned a symbol number
3748 although undeclared string literals have not.
3749 * tests/regression.at (String alias declared after use, Undeclared
3750 string literal): New test cases.
3751 (Characters Escapes, Web2c Actions): Declare string literals as
3753 * tests/sets.at (Firsts): Likewise.
3755 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
3757 In the grammar scanner, STRING_FINISH unclosed constructs and return
3758 them to the parser in order to improve error messages.
3759 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
3760 SC_BRACED_CODE, SC_PROLOGUE): Implement.
3761 * tests/input.at (Unclosed constructs): New test case.
3762 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
3765 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
3768 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
3770 Handle string aliases for character tokens correctly.
3771 * src/symtab.c (symbol_user_token_number_set): If the token has an
3772 alias, check and set its alias's user token number instead of its own,
3773 which is set to indicate the alias. Previously, every occurrence of
3774 the character token in the grammar overwrote that alias indicator with
3776 * tests/input.at (String aliases for character tokens): New test.
3778 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
3780 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
3782 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
3784 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
3785 to prevent failures when building on older platforms.
3786 Check for autopoint failure.
3787 Set XGETTEXT_OPTIONS to values that check for C format strings,
3788 so that translators are warned about them (this also helps
3789 prevent core dumps).
3791 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
3792 function, since it simplifies our code a bit.
3794 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
3795 rather than -W, so we don't get bogus warnings about sign comparisons.
3796 Add -Wpointer-arith, since that warning is useful (it reports code
3797 that does not conform to C89 and that some compilers reject).
3798 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
3799 since it's no longer needed.
3801 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
3803 Clean up scanners a bit.
3804 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
3805 definitions so gcc won't warn when obstack_for_string is unused.
3806 * src/scan-code.l: config.h and system.h are already #include'd by
3807 scan-code-c.c, so get rid of them here.
3808 * src/scan-gram.l: Likewise.
3809 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
3810 definitions rather than duplicating the rest of it.
3811 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
3813 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
3815 Suppress signed/unsigned comparison warnings for yycheck.
3816 * data/c.m4 (b4_safest_int_type): New macro.
3817 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
3818 a signed int type, cast it to b4_safest_int_type first.
3819 * data/yacc.c: Likewise.
3820 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
3823 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
3825 * doc/bison.texinfo: Fix some typos.
3827 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
3829 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
3830 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
3832 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
3833 the latest gnulib does this a different way.
3834 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
3835 translation was patched, so stop omitting it.
3837 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3839 Enable declaration of default %printer/%destructor. Make the parser
3840 use these for all user-declared grammar symbols for which the user does
3841 not declare a specific %printer/%destructor. Thus, the parser uses it
3842 for token 0 if the user declares it but not if Bison generates it as
3843 $end. Discussed starting at
3844 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
3845 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
3847 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
3848 * NEWS (2.3+): Mention.
3849 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
3850 declare a %destructor for a mid-rule's semantic value. It's just
3851 impossible to declare one specific to it.
3852 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
3853 code. Describe default %destructor form.
3854 * src/parse-gram.y (grammar_declaration): Parse default
3855 %printer/%destructor declarations.
3856 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
3857 and symbol_destructor_location_get rather than accessing the destructor
3858 and destructor_location members of struct symbol.
3859 (symbol_printers_output): Likewise but for %printer's.
3860 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
3862 * src/symtab.c (default_destructor, default_destructor_location,
3863 default_printer, default_printer_location): New static global
3864 variables to record the default %destructor and %printer.
3865 (symbol_destructor_get, symbol_destructor_location_get,
3866 symbol_printer_get, symbol_printer_location_get): New functions to
3867 compute the appropriate %destructor and %printer for a symbol.
3868 (default_destructor_set, default_printer_set): New functions to set the
3869 default %destructor and %printer.
3870 * src/symtab.h: Prototype all those new functions.
3871 * tests/actions.at (Default %printer and %destructor): New test to
3872 check that the right %printer and %destructor are called, that they're
3873 not called for $end, and that $$ and @$ work correctly.
3874 (Default %printer and %destructor for user-declared end token): New
3875 test to check that the default %printer and %destructor are called for
3876 a user-declared end token.
3877 * tests/input.at (Default %printer and %destructor redeclared, Unused
3878 values with default %destructor): New tests to check related grammar
3879 warnings and errors.
3881 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3883 Clean up handling of %destructor for the end token (token 0).
3884 Discussed starting at
3885 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
3887 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
3889 Make the skeletons consistent in how they pop the end token and invoke
3891 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
3892 state, which has token number 0, since this would invoke the
3893 %destructor for the end token.
3894 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
3895 until after shifting the end token, or else it won't be popped.
3896 * data/yacc.c (yyparse): Likewise.
3898 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
3899 it's the end token. Upon termination, destroy an unshifted lookahead
3900 even when it's the end token.
3901 * data/lalr1.cc (yy::parser::parse): Likewise.
3902 * data/yacc.c (yyparse): Likewise.
3904 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
3905 value warnings for the end token when the user gives the end token a
3908 * tests/actions.at (Printers and Destructors): Test all the above.
3910 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
3912 Update to latest gnulib and gettext versions.
3913 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
3915 (gnulib_files): Add m4/warning.m4. Don't worry about files
3916 overwritten by autopoint.
3917 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
3918 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
3920 Don't use autoreconf; instead, invoke autopoint etc. by hand,
3921 so that we can remove the intl files at a better time.
3922 (intl_files_to_remove): Remove aclocal.m4, since it gets
3923 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
3924 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
3925 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
3926 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
3927 Remove datarootdir hack; no longer needed.
3928 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
3929 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
3930 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
3932 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
3933 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
3935 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3937 * bootstrap: Adjust to today's change to gnulib-tool by invoking
3938 it with --assume-autoconf='latest-stable'.
3940 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
3942 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
3943 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
3945 * src/muscle_tab.h (muscle_grow): Replace the header comments with
3946 those from muscle_tab.c since the old ones are misleading.
3948 2006-07-13 Akim Demaille <akim@epita.fr>
3950 Support %define "KEY" {VALUE}.
3951 * src/scan-code.h, src/scan-code.l (translate_action)
3952 (translate_rule_action, translate_symbol_action, translate_code):
3953 Return char *, not const char *.
3954 * src/parse-gram.y (declaration): Rename as...
3955 (prologue_declaration): this.
3956 (string_content): Remove this nonterminal, use STRING.
3957 (braceless, content, content.opt): New nonterminal.
3959 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
3961 * src/scan-gram.l (getargs.h): Don't include it.
3963 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
3965 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
3966 rather than a for-loop that declares a local bool variable. This
3967 should work around a compatibility problem with a Cray x1e C++
3968 compiler reported by Hung Nguyen in
3969 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
3970 The for-loop was introduced in the 2004-11-17 change but I don't
3971 know why it was needed.
3973 2006-07-12 Akim Demaille <akim@epita.fr>
3975 * data/c.m4: Comment changes.
3977 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
3979 * src/complain.c (error_message, ERROR_MESSAGE): New.
3981 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
3982 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
3984 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
3986 * NEWS: Instead of %union, you can define and use your own union type
3987 YYSTYPE if your grammar contains at least one <type> tag.
3988 Your YYSTYPE need not be a macro; it can be a typedef.
3989 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
3990 (Union Decl, Decl Summary): Document this.
3991 * data/glr.c (YYSTYPE): Implement this.
3992 * data/glr.cc (YYSTYPE): Likewise.
3993 * data/lalr1.cc (YYSTYPE): Likewise.
3994 * data/yacc.c (YYSTYPE): Likewise.
3995 * src/output.c (prepare): Output tag_seen_flag.
3996 * src/parse-gram.y (declaration, grammar_declaration):
3997 Use 'union_seen' rather than 'typed' to determine whether
3998 %union has been seen, since grammars can now be typed without
4000 (symbol_declaration, type.opt, symbol_def):
4001 Keep track of whether a tag has been seen.
4002 * src/reader.c (union_seen, tag_seen): New vars.
4004 * src/reader.h (union_seen, tag_seen, typed): Likewise.
4005 * src/scan-code.l (untyped_var_seen): New variable.
4006 (handle_action_dollar): Adjust to above changes.
4007 (handle_action_dollar, handle_action_at):
4008 Improve overflow checking for outlandish numbers.
4009 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
4010 avoid new diagnostics generated by above changes.
4011 * tests/regression.at (YYSTYPE typedef): Add test to check
4012 for type tags without %union.
4014 * src/symlist.c (symbol_list_length): Return int, not unsigned
4015 int, since callers expect int. This may need to get revisited
4016 once we have proper integer overflow checking.
4018 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
4019 object is now static.
4021 * src/getargs.c (flags_argmatch): Return void, not int,
4022 to pacify ./configure --enable-gcc-warnings.
4024 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
4025 since last_string is already defined to FLEX_PREFIX (last_string).

4029 Implement --warnings/-W.
4030 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
4032 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
4034 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
4035 (warnings_args, warnings_types): New.
4036 (getargs, short_options, long_options): Accept -W/--warnings.
4037 Sort the options by alphabetical order, upper case letter right
4038 before its lower case.
4040 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4042 Change %merge result type clash warnings to errors. Discussed at
4043 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
4044 * src/reader.c (record_merge_function_type): Use complain_at.
4045 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4046 declared later): Update test case results.
4048 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4050 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
4051 to be in alphabetical order.
4052 (trace_args): Spelling fixes.
4054 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4056 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
4057 so they don't collide with user-defined macros.
4058 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4059 this was never guaranteed, and now that we're using gnulib stdint,
4060 which defines int_fast16_t to long int, the problem is exposed.
4062 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
4064 * data/c.m4 (b4_basename): Simplify a bit, since we don't
4065 need the full POSIX semantics (and weren't implementing them
4068 Adjust to Autoconf 2.60 and today's gnulib.
4069 * bootstrap (gnulib_modules): Add stdint.
4070 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4071 no longer copies it.
4072 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4073 since stdint needs the former and wcwidth (which is now required
4074 by mbswidth) needs the latter.
4075 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4076 work around a compatibility glitch between gettext 0.14.6 and
4078 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
4079 Do not check for uintptr_t, since new stdint module does the right
4081 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
4082 Add stdint.h, stdint_.h, wcwidth.h.
4083 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
4084 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
4085 stdint.m4, wchar_t.m4, wcwidth.m4.
4086 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
4087 usual order for ../lib/*.h files.
4088 (file_name_split): Use last_component, not base_name, to adjust
4090 * src/parse-gram.h: Include <strverscmp.h> in the usual order
4091 for ../lib/*.h files.
4092 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
4093 Define unconditionally, since we now assume the stdint module.
4094 * src/scan-skel.l: Include <dirname.h>.
4095 (BASE_QPUTS): Use last_component, not base_name.
4096 * src/system.h: Include <unlocked-io.h> in the usual order
4097 for ../lib/*.h files. Include <stdint.h> unconditionally,
4098 since we now use the stdint module.
4099 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
4100 HAVE_UINTPTR_T, since we now use the stdint module.
4101 (base_name): Remove decl, since files now include <dirname.h>
4104 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4106 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
4108 * data/yacc.c, data/glr.c, data/location.cc: Use them.
4109 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
4111 * tests/calc.at: Adjust.
4113 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4115 * data/c.m4 (b4_basename): New.
4116 (b4_syncline): Also output the location of its invocation (from
4118 (b4_user_action, b4_define_user_action, b4_user_actions)
4119 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
4120 (b4_user_stype): New.
4121 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
4123 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4125 In the grammar file, the first column is 1 not 0 on the first line as
4126 on every other line.
4127 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
4128 * tests/input.at (Torturing the Scanner): Update output.
4130 * src/scan-gram.l (scanner_cursor): Declare it static.
4132 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4134 In warnings, say "previous declaration" rather than "first
4136 * src/symtab.c (redeclaration): Do that here.
4137 * src/reader.c (record_merge_function_type): In the case of a result
4138 type clash, report the previous declaration rather than the very first
4139 one in the grammar file.
4140 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4141 declared later): Add a third declaration to check this behavior.
4142 * tests/input.at (Incompatible Aliases): Update output.
4144 2006-06-27 Akim Demaille <akim@epita.fr>
4146 * doc/Doxyfile.in: New.
4147 * doc/Makefile.am: Use it.
4148 * src/lalr.h, src/symtab.h: Initial doxygenation.
4150 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4152 Don't miss %merge result type warnings just because the LHS types are
4153 declared after the %merge. This continues the effort of the previous
4155 * src/reader.c (get_merge_function): Don't set the merger type yet.
4156 (record_merge_function_type): New function for setting the merger type
4157 and checking for clashes.
4158 (grammar_current_rule_merge_set): Set the location of the %merge for
4160 (packgram): Invoke record_merge_function_type for each rule now that
4161 all symbol type declarations have been parsed.
4162 * src/reader.h (merger_list.type_declaration_location): New member
4163 storing the location of the first %merge from which the type for this
4164 merging function was derived.
4165 * src/symlist.h (symbol_list.merger_declaration_location): New member
4166 storing the location of a rule's %merge, if any.
4167 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4168 declared later): New test to catch the error fixed by the above patch.
4170 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4172 Get action warnings (grammar_rule_check) right even when symbol
4173 declarations appear after the rules. Discussed at
4174 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
4176 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
4177 Don't mistake the type of $$ in a midrule to be that of its parent
4179 * src/reader.c (grammar_current_rule_end): Don't invoke
4180 grammar_rule_check yet since not all symbol declarations may have been
4182 (grammar_midrule_action): Likewise.
4183 Don't record whether the midrule's $$ has been used yet since actions
4184 haven't been translated yet.
4185 Record the midrule's parent rule and its RHS index within the parent
4187 (grammar_current_rule_action_append): Don't translate the action yet
4188 since not all symbol declarations may have been parsed yet and, thus,
4189 warnings about types for $$, $n, @$, and @n can't be reported yet.
4190 (packgram): Translate the action and invoke grammar_rule_check now that
4191 all symbol declarations have been parsed.
4192 * src/scan-code.l (handle_action_dollar): Now that this is invoked
4193 after parsing the entire grammar file, the symbol list here in the case
4194 of a midrule is actually the midrule's empty RHS, so reference its
4195 parent rule's RHS where necessary.
4196 On the other hand, now that you can already know it's a midrule, you
4197 aren't forced to think $$ has the same type as its parent rule's $$.
4198 (handle_action_at): In the case of a midrule, reference the parent rule
4200 * src/symlist.c (symbol_list_new): Initialize new midrule-related
4202 (symbol_list_length): Now that this is invoked after all rules have
4203 been parsed, a NULL symbol (rather than a NULL symbol list node)
4204 terminates a rule. symbol_list_print already does this correctly.
4205 * src/symlist.h (symbol_list.midrule_parent_rule,
4206 symbol_list.midrule_parent_rhs_index): New members so that midrules can
4207 remember their relationships with their parents.
4208 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
4209 fixed by the above patch.
4210 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
4212 (Unused values): ... this old test case and...
4213 (Unused values before symbol declarations): ... this new test case.
4214 This one is the same as `Unused values' except that all symbol
4215 declarations appear after the rules in order to catch the rest of the
4216 errors fixed by the above patch.
4218 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4221 * src/reader.c (current_rule): Declare it static since it's no longer
4222 used outside this file.
4223 (grammar_current_rule_action_append): Remove redundant arguments from
4224 translate_rule_action invocation.
4225 * src/reader.h (current_rule): Remove this unused extern.
4226 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
4227 * src/scan-code.l (translate_rule_action): Likewise.
4229 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
4231 Clean up yesterday's patch.
4232 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
4234 * src/reader.c (grammar_current_rule_action_append): ... here for
4235 consistency with grammar_current_rule_symbol_append.
4236 * tests/regression.at (Braced code in declaration in rules section):
4237 Make yyerror and yylex static as usual.
4239 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
4241 Fix bug that mistakes braced code in a declaration in the rules section
4242 to be a rule action. Mentioned at
4243 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
4244 * src/scan-gram.l: Move midrule action detection from the start of the
4245 scanning of any braced code to...
4246 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
4247 action. For readability, use $2 and @2 rather than the equivalent
4249 * tests/regression.at (Braced code in declaration in rules section):
4250 New test to catch the error fixed by the above patch.
4252 Work on code readability some.
4253 * src/scan-code.l (current_rule): Get rid of this misleading and
4254 redundant declaration: it's actually extern'ed in reader.h.
4255 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
4256 translate_action): Add a rule argument and use it instead of the global
4258 (translate_rule_action): This already receives current_rule through an
4259 argument, so pass it on to translate_action instead of assigning
4260 current_rule to current_rule.
4261 (translate_symbol_action, translate_code): Pass rule = NULL to
4264 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
4266 Rename %before-definitions to %start-header and %after-definitions to
4267 %end-header. Don't use these declarations to separate pre-prologue
4268 blocks from post-prologue blocks. Add new order-independent
4269 declarations %before-header and %after-header as alternatives to the
4270 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
4271 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
4272 * NEWS (2.3+): Update for these changes.
4273 * data/glr.c (b4_before_definitions): Update to...
4274 (b4_start_header): ... this.
4275 (b4_after_definitions): Update to...
4276 (b4_end_header): ... this.
4277 * data/glr.cc: Likewise.
4278 * data/lalr1.cc: Likewise.
4279 * data/yacc.c: Likewise.
4280 * doc/bison.texinfo (The prologue): Update names, and replace remaining
4281 prologue blocks with %*-header declarations.
4282 (Calc++ Parser): Likewise.
4283 (Decl Summary): Update names.
4284 (Table of Symbols): Update description.
4285 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
4286 (PERCENT_END_HEADER): ... this.
4287 (PERCENT_BEFORE_DEFINITIONS): Update to...
4288 (PERCENT_START_HEADER): ... this.
4289 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4290 (declaration): Update token names and m4 macro names.
4291 When parsing %end-header and %start-header, invoke translate_code
4292 before muscle_code_grow, and no longer set global booleans to remember
4293 whether these declarations have been seen.
4294 Parse new %after-header and %before-header.
4295 * src/reader.c (before_definitions, after_definitions): Remove.
4296 (prologue_augment): Accept a new bool argument to specify whether to
4297 augment the pre-prologue or post-prologue.
4298 * src/reader.h (before_definitions, after_definitions): Remove these
4300 (prologue_augment): Add new bool argument.
4301 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
4302 (PERCENT_END_HEADER): ... this.
4303 (PERCENT_BEFORE_DEFINITIONS): Update to...
4304 (PERCENT_START_HEADER): ... this.
4305 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4306 * tests/actions.at (Printers and Destructors): Update names.
4308 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
4310 Add comparison operators for C++ location classes. Discussed at
4311 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
4312 * data/c++.m4 (b4_define_location_comparison): New boolean %define
4313 declaration indicating whether filename_type has an operator==. If
4314 filename_type is `std::string', it defaults to `1', `0' otherwise.
4315 * data/location.cc: Iff b4_define_location_comparison is `1', add
4316 operator== and operator!= for class position and for class location.
4319 * src/scan-action.l: Remove unused file.
4320 * src/symtab.c (symbol_printer_set): Use printer_location not
4321 destructor_location.
4322 * src/symtab.h (struct symbol): Replace incorrect source comment for
4324 * tests/input.at (Incompatible Aliases): Update output with correct
4327 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
4329 Don't put the pre-prologue in the header file. For the yacc.c code
4330 file and the glr.c header and code files, move the pre-prologue before
4331 the token definitions. Add new %before-definitions and
4332 %after-definitions to declare code that will go in both the header file
4333 and code file. Discussed at
4334 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
4335 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
4337 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
4338 * NEWS (2.3+): Describe these changes.
4339 * data/glr.c (b4_pre_prologue): Move from within to before...
4340 (b4_shared_declarations): ... this.
4341 Add new b4_before_definitions before b4_token_enums.
4342 Add new b4_after_definitions at the end.
4343 * data/glr.cc (b4_pre_prologue): Replace with...
4344 (b4_before_definitions): ... this in the header file.
4345 (b4_after_definitions): New near the end of the header file.
4346 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
4347 code file right before including the header file.
4348 (b4_before_definitions): New in the previous position of
4349 b4_pre_prologue in the header file.
4350 (b4_after_definitions): New near the end of the header file.
4351 * data/yacc.c: Clean up some m4 quoting especially in the header file.
4352 (b4_token_enums_defines): In the code file, move to right before
4353 YYSTYPE for consistency with the header file.
4354 (b4_before_definitions): New right before b4_token_enums_defines in
4355 both the header and code file.
4356 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
4357 header and code file.
4358 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
4359 of prologues for %union dependencies.
4360 (Decl Summary): In %defines description, mention the effect of
4361 %before-definitions and %after-definitions on the header file.
4362 (Calc++ Parser): Forward declare driver in a %before-definitions rather
4363 than in the pre-prologue so that make check succeeds.
4364 (Table of Symbols): Add entries for %before-definitions and
4366 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
4367 %before-definitions.
4368 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
4369 (declaration): Parse those declarations and append to
4370 b4_before_definitions and b4_after_definitions, respectively.
4371 * src/reader.c (before_definitions, after_definitions): New bools to
4372 track whether those declarations have been seen.
4373 (prologue_augment): Add to the post-prologue if %union,
4374 %before-definitions, or %after-definitions has been seen.
4375 * src/reader.h (before_definitions, after_definitions): New extern's.
4376 * src/scan-gram.l: Scan the new declarations.
4377 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
4378 prologue block in a %before-definitions or a %after-definitions based
4379 on whether the %union is declared.
4380 * tests/regression.at (Early token definitions with --yacc, Early token
4381 definitions without --yacc): Move tests for token definitions into the
4382 post-prologue since token names are no longer defined in the
4385 2006-06-20 Akim Demaille <akim@epita.fr>
4387 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
4388 (symbol_get): Use it.
4389 * src/parse-gram.y: Use it.
4391 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
4393 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
4394 build succeeds when configured with --enable-gcc-warnings.
4396 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4398 * src/parse-gram.y (char_name): New function.
4399 (CHAR, STRING, string_content): For %printer, properly escape.
4400 (ID): Prefer fputs to fprintf.
4401 (id): Reindent to be consistent with other rules.
4402 Properly quote char.
4404 The Translation Project changed its way of publishing translations
4405 to maintainers. I haven't received any responses to my request
4406 for supporting the old way, or for documenting the new way. I
4407 have modified 'bootstrap' to use screen scraping
4408 (in this case, HTML scraping). This is unreliable and inelegant,
4409 but I don't see any better way. Yuck.
4410 * bootstrap (TP_URL, WGET_COMMAND): New vars.
4411 (get_translations): New function, which uses HTML scraping to
4412 deduce locations of latest translations.
4413 Use this function to grab both bison and bison-runtime .po files.
4414 Don't bother priming the pump for the runtime-po domain any more,
4415 as it's now translated better than bison is.
4417 2006-06-19 Akim Demaille <akim@epita.fr>
4419 * src/scan-gram.l: No longer "parse" things after `%union' until
4420 `{'. Rather, return a single "%union" token.
4421 No longer make symbols: return strings, and leave the conversion
4422 to symbols to the parser.
4423 (SC_PRE_CODE, token_type): Remove.
4424 * src/parse-gram.y (%union): New field `character'.
4427 (ID, ID_COLON): Now that the scanner no longer makes them
4428 identifiers, adjust all uses to invoke symbol_get.
4429 (id_colon): New, wraps the conversion from string to symbol.
4430 (%union): Accept a possible union_name.
4431 (symbol): Now can be a char.
4432 * data/c.m4 (b4_union_name): Leave a default value.
4433 * data/glr.c, data/yacc.c: Use it.
4435 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
4437 For associating token numbers with token names for "yacc.c", don't use
4438 #define statements unless `--yacc' is specified; always use enum
4439 yytokentype. Most important discussions start at:
4440 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
4441 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
4443 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
4444 * NEWS (2.3+): Mention.
4445 * data/c.m4 (b4_yacc_if): New.
4446 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
4448 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
4449 on token name definitions.
4450 * src/getargs.c (usage): Capitalize `Yacc' in English.
4451 * src/output.c (prepare): Define b4_yacc_flag.
4452 * tests/regression.at (Early token definitions): Test that tokens names
4453 are defined before the pre-prologue not just before the post-prologue.
4454 Remove this test case and copy to...
4455 (Early token definitions with --yacc): ... this to test #define's.
4456 (Early token definitions without --yacc): ... and this to test enums.
4458 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
4460 * NEWS: Reword the post-2.3 change to not be so optimistic about
4461 removing the old "look-ahead" spelling.
4462 Update previous look-ahead/lookahead change reports.
4463 * REFERENCES: look-ahead -> lookahead (since that's
4464 what he actually wrote).
4465 * doc/refcard.tex: look ahead -> lookahead,
4466 look-ahead -> lookahead

4553 and yytext if they're already #define'd.
4554 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
4555 * src/scan-code-c.c: ... here.

4561 Get Bison to build again when configured with --enable-gcc-warnings.
4562 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
4564 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
4565 loc argument as it shadows a global.
4566 * src/scan-gram.l: Remove stray comma that prevents boundary_set

4571 2006-06-07 Akim Demaille <akim@epita.fr>
4573 * src/scan-gram.l: Move the "add a trailing ; to actions" code
4575 * src/scan-code.l: here.

4583 2006-06-06 Akim Demaille <akim@epita.fr>
4585 Extract the parsing of user actions from the grammar scanner.
4586 As a consequence, the relation between the grammar scanner and
4587 parser is much simpler. We can also split "composite tokens" back
4589 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
4590 * src/scan-gram.l (add_column_width, adjust_location): Move to and
4592 * src/location.h, src/location.c (add_column_width)
4593 (location_compute): these.
4594 Fix the column count: the initial column is 0.
4595 (location_print): Be robust to ending column being 0.
4596 * src/location.h (boundary_set): New.
4597 * src/main.c: Adjust to scanner_free being renamed as
4599 * src/output.c: Include scan-code.h.
4600 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
4602 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)

4649 Use Akim's wording from
4650 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
4652 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4654 Between Bison releases, manually append `+' to the previous Bison
4655 release number, and use that as a signal to automatically print the
4656 ChangeLog's CVS Id keyword from --version. Discussed starting at
4657 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
4658 * ChangeLog: Add Id header.
4659 * configure.ac (AC_INIT): Append `+' to `2.3'.
4660 * src/.cvsignore: Add revision.c.
4661 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
4662 (BUILT_SOURCES): Add revision.c.
4663 (revision.c): New target rule. This file defines a new global variable
4664 named revision. It initializes it with either the Id from ChangeLog
4665 or, if VERSION doesn't contain `+', with the empty string.
4666 * src/getargs.c (version): Print the value of revision.
4667 * src/revision.h: Extern revision.
4669 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4671 * NEWS: Version 2.3.
4672 * configure.ac (AC_INIT): Likewise.
4674 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4676 * data/glr.c (YYRECOVERING): Define to be a function-like macro
4677 with no arguments, not as an object-like macro. This is for
4678 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
4679 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
4680 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
4683 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
4685 * src/getargs.c (usage): Back out yesterday's modification of the
4686 --help output so that we don't have to wait for translation before
4689 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4691 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
4692 Problem reported by Akim Demaille.
4694 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4696 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4698 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4700 * data/yacc.c (yy_reduce_print): Omit trailing white space in
4701 generated source code. Problem reported by Frans Englich in
4702 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
4704 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
4706 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
4707 shell, not within 'make', so that 'make' by an ordinary builder
4708 (using GNU make) does not worry about configuring gzip. This also
4709 works around a bug reported independently by Keith Thompson and by
4710 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
4711 stderr rather than stdout, messing up the build logs.
4713 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4715 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
4716 to make sure that YYID will never be unused. This fixes a 'make
4717 maintainer-check' failure caused by the recent changes to the 'Trivial
4718 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
4720 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
4722 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4724 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
4725 state before an empty RHS is always resolved here. Only the location
4726 of that state is guaranteed to be resolved, and that's enough. This
4727 fixes the remaining bug reported by Derek M. Jones in
4728 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4729 * tests/glr-regression.at (Uninitialized location when reporting
4730 ambiguity): Test the above case.
4731 Also, the embedded comments in this test case claim it checks the case
4732 of an empty RHS that has inherited the initial location. However, the
4733 corresponding LHS was already resolved, so yyresolveLocations didn't
4734 actually have reason to modify it. Fix this by forcing
4735 nondeterministic operation at the beginning of the parse.
4737 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4739 * data/c.m4 (b4_yy_symbol_print_generate):
4740 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
4741 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
4742 of the bugs reported today by Derek M Jones in
4743 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4744 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
4745 defined to be a type name without parens or brackets.
4746 (Location Type): Similarly for YYLTYPE.
4747 * tests/regression.at (Trivial grammars): Put in a test for this
4748 bug that will be caught by 'make maintainer-check' (though not,
4749 alas, by 'make check' unless your compiler is picky).
4751 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4753 * NEWS: Version 2.2.
4754 * configure.ac (AC_INIT): Likewise.
4756 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
4758 * data/glr.c (yyreportTree): Make room in yystates for the state
4759 preceding the RHS. This fixes the segmentation fault reported by Derek
4761 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
4762 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
4763 to the user. Reported for yyreportTree by Derek M. Jones later in the
4765 * THANKS: Add Derek M. Jones.
4766 Update my email address.
4767 Fix typo in Steve Murphy's name.
4769 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4771 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
4772 checking against YYLAST that caused the parser to miss a potential
4773 alternative in its diagnostic.
4774 Problem reported by Maria Jose Moron Fernandez in
4775 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
4776 * data/lalr1.cc (yysyntax_error_): Likewise.
4777 * data/yacc.c (yysyntax_error): Likewise.
4778 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
4779 tokens, in case we run into an older C compiler.
4780 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
4781 Use them to check for the off-by-one error fixed above.
4783 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
4784 YYSIZE_T, not size_t.
4785 * tests/regression.at (Trivial grammars): New test, to catch
4786 the error fixed by the above patch.
4788 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4790 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
4792 Reported by Steve Murphy.
4794 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4796 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
4797 * data/glr.cc: b4_location_flag is now b4_locations_flag.
4799 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4801 Implement --trace=m4.
4802 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
4803 * src/output.c (output_skeleton): When set, pass -dV to m4.
4805 Factor the handling of flags in m4.
4806 * src/output.c (prepare): Rename the muscle names debug, defines,
4807 error_verbose to debug_flag, defines_flag, error_verbose_flag.
4808 * data/c.m4: Adjust.
4809 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
4810 Use b4_define_flag_if to define other b4_FLAG_if macros.
4811 (b4_location_if): As a consequence, rename as...
4812 (b4_locations_if): this, for consistency.
4813 Adjust all the skeletons.
4815 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4817 * etc/bench.pm: Shorten bench names.
4819 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4821 * src/output.h, src/output.c (error_verbose): Move to...
4822 * src/getargs.h, src/getargs.c: here.
4824 Adjust dependencies.
4826 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4828 * data/c.m4 (b4_copyright): Put the special exception for Bison
4829 skeletons here, so we don't have to put it in each skeleton. All
4830 uses changed. Suggested by Akim Demaille. Also, wrap the
4831 copyright notice, in case it is longer than 80 columns. Replace
4832 comma by newline after title.
4834 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4836 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
4837 incompatibility, not a bug. Mention that it wasn't fixed as of
4840 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4842 * examples/extexi: Enforce the precedence of concatenation over
4844 Reported by Tommy Nordgren.
4846 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4848 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
4849 with the member "token".
4850 Reported by Martin Nylin.
4852 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
4854 * data/glr.c: Switch to Bison 2.2 special-exception language in
4855 the copyright notice. Use more-regular format for titles and
4857 * data/glr.cc: Likewise.
4858 * data/location.cc: Likewise.
4859 * data/yacc.cc: Likewise.
4860 * doc/bison.texinfo (Conditions): Document this.

4865 * data/glr.cc: Remove dead code.
4867 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4869 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
4870 that variable and the line breaks the bootstrap. Problem reported
4871 by Juan M. Guerrero.
4873 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
4875 * doc/bison.texinfo (Multiple start-symbols): New.

4888 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
4890 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
4891 Problem reported by Bob Rossi.
4893 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
4895 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
4896 and didn't really work.
4897 For the index, use @ifnotinfo, not @iftex.
4898 Minor cleanups of spacing and terminology.
4900 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4902 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
4903 of AT_NAME_PREFIX when %name-prefix is not used.
4905 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4907 Apply --prefix to C++ skeletons too: they change the namespace.
4908 The test suite already exercize these cases.
4909 * data/c++.m4 (b4_namespace): New.
4910 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.

4912 * data/yacc.c, data/glr.c: Remove a useless `[]'.
4913 * doc/bison.texinfo: Document it.

4938 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
4940 Fix two nits reported by twlevo, plus one more that I discovered.
4942 * src/assoc.h (assoc_to_string): Give a name to the arg, as
4943 this is the usual Bison style.
4944 * src/location.h (location_print): Likewise.
4946 * src/reader.h (token_name): Likewise.
4948 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
4950 Fix some nits reported by twlevo.
4951 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
4952 and "POSIX". Use more-modern syntax for URLs. Mention C++
4953 and ask for Java. Don't hardwire OS version numbers. Add
4955 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
4956 * src/conflicts.c (solved_conflicts_obstack): Now static.
4958 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
4960 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
4961 page. Say "you can use it" not "you may use it" as on the web page;
4962 we're describing capabilities not granting permission.
4964 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
4966 * data/glr.c (yyresolveLocations): Rename local variables to avoid
4967 shadowing warnings. Use usual patter for iterating through RHS.
4968 * tests/glr-regression.at
4969 (Uninitialized location when reporting ambiguity):
4970 Modify yylex so that it uses its argument, rather than trying
4971 to rely on ARGSUSED (which doesn't work for gcc with warnings).
4972 const char -> char const.
4974 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
4975 Don't use tabs inside commands; it messes up 'ps'.
4976 Problem reported by twlevo.
4978 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
4980 * tests/glr-regression.at (Uninitialized location when reporting
4981 ambiguity): New test case.
4982 * data/glr.c (yyresolveLocations): New function, which uses
4984 (yyresolveValue): Invoke yyresolveLocations before reporting an
4986 * doc/bison.texinfo (Default Action for Locations): Note
4987 YYLLOC_DEFAULT's usage for ambiguity locations.
4988 (GLR Semantic Actions): Cross-reference those notes.
4990 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
4992 * tests/glr-regression.at (Leaked semantic values when reporting
4993 ambiguity): Remove unnecessary union and type declarations.
4994 (Leaked lookahead after nondeterministic parse syntax error): New test
4996 * data/glr.c (yyparse): Check for zero stacks remaining before
4997 attempting to shift the lookahead so that you don't lose it.
4999 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5001 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
5002 * tests/glr-regression.at (Leaked semantic values when reporting
5003 ambiguity): New test case.
5004 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
5005 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
5006 now unnecessary yystackp parameter.
5007 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
5008 destructors can be called.
5010 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
5011 in existing testcases.
5013 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5015 Don't leak semantic values for parent RHS when a user action cuts the
5016 parser, and clean up related code a bit.
5017 * tests/glr-regression.at (Leaked merged semantic value if user action
5018 cuts parse): Rename to...
5019 (Leaked semantic values if user action cuts parse): ... this. Add check
5020 for leaked parent RHS values.
5021 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
5022 between an unresolved state (non-empty chain of semantic options) and
5023 an incomplete one (signaled by an empty chain).
5024 (yyresolveStates): Document the interface. Move all manipulation of a
5025 successfully or unsuccessfully resolved yyGLRState to...
5026 (yyresolveValue): ... here so that yyresolveValue always leaves a
5027 yyGLRState with consistent data and thus is easier to understand.
5028 Remove the yyvalp and yylocp parameters since they are always just
5029 taken from the yys parameter. When reporting a discarded merged value
5030 in debugging output, note that it is incompletely merged. Document the
5032 (yyresolveAction): If resolving any of the RHS states fails, destroy
5033 them all rather than leaking them. Thus, as long as user actions are
5034 written to clean up the RHS correctly, yyresolveAction always cleans up
5035 the RHS of a semantic option. Document the interface.
5037 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
5039 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
5040 led to a segmentation fault in GNU Pascal. Problem reported
5043 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
5045 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
5046 mid-rule action inside a nonterminal symbol in order to declare a
5047 destructor for its semantic value.
5049 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>

5053 __cplusplus && ! defined _STDLIB_H && !
5054 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
5055 defined free))]: Include <stdlib.h> rather than rolling our own
5056 declarations of malloc and free, to avoid problems with
5057 incompatible declarations (using 'throw') C++'s stdlib.h. This
5058 should fix Debian bug 340012

5070 * NEWS: Version 2.1a.
5071 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
5072 since C99 requires this.
5074 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
5076 * m4/c-working.m4: New file.
5077 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
5079 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
5081 * Makefile.maint: Merge from coreutils.
5083 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
5085 More portability fixes for problems summarized by Nelson H. F. Beebe.
5087 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a

5089 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
5090 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

5096 More portability fixes for problems summarized by Nelson H. F. Beebe.
5098 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
5099 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
5101 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
5102 nodist_PROGRAMS, since we don't need to actually compile the
5103 example if we're just doing a plain 'make'. This avoids bothering
5104 the installer unnecessarily about problems due to weird C++

5109 More portability fixes for problems summarized by Nelson H. F. Beebe.
5111 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
5112 than #include "...", and compile with -I'.'. The old method was
5113 not portable, according to Posix and the C standard, and it does
5114 not work with Sun C 5.7, where previous #line directives affect
5115 the working directory used in later #include "..." directives.

5126 '#include <map>' works and that you can apply ++ to iterators.
5128 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
5130 Work around portability problems summarized by Nelson H. F. Beebe in

5134 that '#include <string>' works.
5136 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
5137 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
5138 "warning: sorry: semantics of inline function static data `const
5139 unsigned char translate_table[262]' are wrong (you'll wind up with
5142 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
5143 or, xor to not_, and_, or_, and xor_, respectively. This works
5144 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
5145 random system header somewhere that includes the equivalent of
5148 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
5149 -E" works; it apparently doesn't work with PathScale EKO Compiler
5152 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
5154 During deterministic GLR operation, user actions should be able to
5155 influence the parse by changing yychar. To make this easier to fix and
5156 to make glr.c easier to evolve in general, don't maintain yytoken in
5157 parallel with yychar; just compute yytoken when needed.
5158 * tests/glr-regression.at (Incorrect lookahead during deterministic
5159 GLR): Check that setting yychar in a user action has the intended
5161 * data/glr.c (yyGLRStack): Remove yytokenp member.
5162 (yyclearin): Don't set *yytokenp.
5163 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
5164 yychar rather than *yytokenp to determine the current lookahead.
5165 Compute yytoken locally when needed.
5166 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
5169 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
5170 after `--report' documentation.

5178 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>

5181 all the test at once. This makes the output easier to read in the
5184 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
5185 got from <http://bro-ids.org/download.html>. The bug is that
5186 when two actions appeared in succession, the second one was
5187 scanned before the first one was added to the grammar rule
5188 as a midrule action. Bison then output the incorrect warning
5189 "parse.y:905.17-906.36: warning: unused value: $3".
5190 * src/parse-gram.y (BRACED_CODE, action): These are no longer
5191 associated with a value.
5192 (rhs): Don't invoke grammar_current_rule_action_append.
5193 (action): Invoke it here instead.
5194 * src/reader.c (grammar_midrule_action): Now extern.
5195 (grammar_current_rule_action_append): Don't invoke
5196 grammar_midrule_action; that is now the scanner's job.
5197 * src/reader.h (last_string, last_braced_code_loc):
5198 (grammar_midrule_action): New decls.
5199 * src/scan-gram.l (last_string): Now extern, sigh.
5200 (last_braced_code_loc): New extern variable.
5201 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
5202 rule already has an action.
5203 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
5204 * tests/input.at (AT_CHECK_UNUSED_VALUES):
5205 Add some tests to check that the above changes fixed the bug.
5207 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
5209 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
5210 All used changed. Check whether the symbol has a destructor,
5211 not whether it is typed.
5212 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
5213 that the values are still reported as unused. All line numbers

5260 since we don't want to insist on a version number at the start
5261 of the changelog every time.

5410 (sc_useless_cpp_parens): New rule.
5411 (news-date-check): Look for version or today's date.
5412 (changelog-check): Don't require version number near head.
5413 (copyright-check): Use current year instead of hardwiring 2005.
5414 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
5415 (announcement): Add --gpg-key-ID.
5417 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
5420 Avoid undefined behavior that addressed just before the start of an
5421 array. Problem reported by twlevo.

5450 (Special Features for Use in Actions): Add YYEOF entry and mention it
5451 in the yychar entry.
5452 In the yychar entry, remove mention of the local yychar case (pure
5453 parser) since this is irrelevant information when writing semantic
5454 actions and since it's already discussed in `Table of Symbols' where
5455 yychar is otherwise described as an external variable.
5456 In the yychar entry, don't call it the `current' look-ahead since it
5457 isn't when semantic actions are deferred.
5458 In the yychar and yyclearin entries, add note about deferred semantic
5460 Add yylloc and yylval entries discussing look-ahead usage.
5461 (Look-Ahead Tokens): When discussing yychar, don't call it the

5471 * tests/glr-regression.at: Update copyright year to 2006.
5473 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5475 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
5476 use during nondeterministic operation to track which stacks have
5477 actually needed the current lookahead.
5478 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
5479 Allocate, deallocate, resize, and otherwise shuffle space for
5480 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.

5482 appropriately during nondeterministic operation.
5483 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
5484 members to store the current lookahead to be used by the deferred
5486 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
5487 from which the RHS is taken. Set the lookahead members of the new
5488 yySemanticOption according to the lookahead status for stack yyk.

5490 yyaddDeferredAction.
5491 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

5497 titles for consistency.
5498 (Leaked merged semantic value if user action cuts parse): In order to
5499 suppress lint warnings, use arguments in merge function, and assign
5500 char value < 128 in main.
5501 (Incorrect lookahead during deterministic GLR): New test case.
5502 (Incorrect lookahead during nondeterministic GLR): New test case.
5504 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5506 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
5507 !yyvaluep as signal that no semantic value is available to print.

5513 * tests/glr-regression.at: For consistency with my newer test cases,
5516 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5518 * data/glr.c (yyresolveValue): When merging semantic options, if at
5519 least one user action succeeds but a later one cuts the parse, then
5520 destroy the semantic value before returning rather than leaking it.
5521 (yyresolveStates): If a user action cuts the parse and thus
5522 yyresolveValue fails, ignore the (unset) semantic value rather than
5523 corrupting the yyGLRState, and empty the semantic options list since
5524 the user actions should have called all necessary destructors.
5525 Simplify code with YYCHK.
5526 * tests/glr-regression.at (Corrupted semantic options if user action
5527 cuts parse): New test case.
5528 (Undesirable destructors if user action cuts parse): New test case.
5529 Before applying any of this patch, this test case never actually failed
5530 for me... but only because the corrupted semantic options usually

5572 * doc/bison.texinfo (Bison Options): Say more accurately what
5574 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
5575 about declarations in the grammar when in Yacc mode, as POSIX does
5576 not require a diagnostic when the grammar uses extensions.
5578 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
5580 Warn about dubious constructions like "%token T T".
5582 * src/symtab.h (struct symbol.declared): New member.

5584 (symbol_class_set): New arg DECLARING, specifying whether
5585 this is a declaration that we want to warn about, if there
5586 is more than one of them. All uses changed.

5604 (b4_parse_param): Improve its definition, and bound it more
5605 clearly in the skeleton.
5606 (b4_epilogue): Append, instead of prepending, in order to keep

5725 Undo 2005-12-01 tentative license wording change. The wording is
5726 still being reviewed by the lawyers, and we don't want to wait for

5770 `if (YYID (N))' to pacify lint.
5772 2005-12-21 Akim Demaille <akim@epita.fr>
5774 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
5775 destroy the RHS symbols of a rule.
5776 * data/yacc.c (yylen): Initialize to 0.
5777 Keep its value to the number of items to possibly shift.
5778 In particular, a regular successful parse that ends on YYFINAL by
5779 a (internal) YYACCEPT must not have yylen != 0.
5780 (yyerrorlab, yyreturn): Pop the RHS.
5781 Reorder a bit to emphasize the `shifting' bits of code.

5792 * djgpp/config.bat: Replace every occurence of the file name
5793 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
5794 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
5795 * djgpp/config.sed: Replace every occurence of the file name
5796 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

5825 * tests/sets.at (Accept): Fix typos in regular expression used to
5826 sed out the final state number.
5828 Work around portability problem on Solaris 10: flex-generated
5829 files include <stdio.h> before <config.h>, which messes up
5830 because the latter defines __EXTENSIONS__. Address the problem
5831 by creating two new little files that include <config.h> first,
5832 then include the flex-generated files. Rewrite everyone else
5833 to include <config.h> first, as well.
5834 * lib/timevar.c: Always include "config.h".

6173 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
6175 Undo the parts of the unlocked-I/O change that substituted
6176 putc or puts for printf. This might hurt performance a bit,
6177 but some people prefer the printf style.

6208 Use unlocked I/O for a minor performance improvement on hosts like
6209 GNU/Linux and Solaris that support unlocked I/O. The basic idea
6210 is to use the gnlib unlocked-io module, and to prefer putc and

6354 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
6356 (yysyntax_error_): Takes the state number as argument.
6357 (yyreduce_print_): Use the argument yyrule, not the former
6360 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
6362 * bootstrap (gnulib_modules): Add verify.
6363 * lib/.cvsignore: Add verify.h.

6369 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
6371 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
6372 local variables whose names begin with 'yy'.
6373 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
6374 Trivial changes from Joel E. Denny.
6376 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
6378 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
6379 don't use alloca any more.
6381 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
6382 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
6383 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
6384 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
6385 to match yacc.c, to test more hosts.
6387 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
6389 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
6390 doesn't affect behavior.
6391 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
6393 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
6394 This works a bit better with glibc, if user code has already included
6396 * doc/bison.texinfo (Bison Parser): Document that users can't
6397 arbitrarily use malloc and free for other purposes. Document
6398 that <alloca.h> and <malloc.h> might be included.
6399 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
6400 user must declare alloca.

6405 2005-09-20 Akim Demaille <akim@epita.fr>
6407 * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
6409 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
6411 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
6412 (YYSTACK_ALLOC_MAXIMUM): Use it.
6413 (yysyntax_error): New function.
6414 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
6415 multiple syntax errors are reported, and alloca is being used.
6416 Instead, reallocate buffers twice as big each time, so that
6417 we waste at most half the allocated memory. Start with a small
6418 (128-byte) buffer that will suffice in most cases anyway.
6419 Use yysyntax_error to do most of the work.
6421 * doc/bison.texinfo (Error Reporting, Table of Symbols):
6422 yynerrs is the number of errors reported, not the number of
6425 * tests/glr-regression.at (Duplicated user destructor for lookahead):
6426 Mark it as expected to fail.
6427 Cast result of malloc; problem reported by twlevo@xs4all.nl.
6428 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
6429 Don't start user-code symbols with "yy", to avoid name space problems.
6431 2005-09-19 Akim Demaille <akim@epita.fr>
6433 Remove the traits, failed experiment.
6434 It never proved useful, and anyway because of the current
6435 definition, it was not possible to have several specialization of
6436 this traits, making it useless.
6437 * data/lalr1.cc (yy:traits): Remove.
6438 Inline its definitions in the parser class.
6440 2005-09-19 Akim Demaille <akim@epita.fr>

6463 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
6464 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
6465 is not defined. This is an awful hack, but it's enough for now.
6466 All callers changed.
6467 * tests/glr-regression-at (make_value): Args are const pointers now,
6468 to avoid GCC warning.
6469 (Duplicated user destructor for lookahead): New test. Currently
6470 skipped. It fails on my host but I'm not sure it'll always fail.
6472 2005-09-16 Akim Demaille <akim@epita.fr>
6474 * src/symtab.h (struct symbol): Declare the printer and destructor
6475 as const, to avoid accidental calls to free.
6476 (symbol_destructor_set, symbol_printer_set): Adjust.
6477 * src/symtab.c: Adjust.
6479 2005-09-16 Akim Demaille <akim@epita.fr>
6481 * data/c.m4 (b4_token_enums): New.
6482 (b4_token_defines): Rename as...
6483 (b4_token_enums_defines): this.
6484 (b4_token_defines): New, output only the #defines.
6485 * data/yacc.c, data/glr.c: Adjust.
6486 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
6487 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
6490 2005-09-16 Akim Demaille <akim@epita.fr>
6492 * data/lalr1.cc (yylex_): Remove, inline its code.
6493 (yyreport_syntax_error_): Remove, replaced by...
6494 (yysyntax_error_): this which returns a string and leaves to the
6495 caller the call to the users' error function.
6496 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
6497 Move from members of the parser object...
6498 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
6499 to local variables of the parse function.
6501 2005-09-16 Akim Demaille <akim@epita.fr>
6503 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
6504 since it's in Bison's name space.
6506 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
6508 * data/glr.c (yyresolveValue): Add default case to pacify
6509 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
6511 * NEWS: Document when yyparse started to return 2.
6512 * doc/bison.texinfo (Parser Function): Document when yyparse
6515 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
6516 (b4_filename_type): Renamed back from b4_file_name_type. All uses
6518 (class position): file_name -> filename (reverting). All uses changed.
6520 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
6522 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
6523 do anything if $@ exists. This reverts part of the 2005-07-07
6526 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
6528 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
6529 contains obsolete information and isn't worth distributing as a
6530 separate file anyway.
6531 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
6532 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
6533 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
6534 (yyparse): Abort if user code uses longjmp to throw an unexpected
6537 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
6539 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
6540 Suggested by twlevo@xs4all.nl.
6542 * data/glr.c (YYCHK1): Do not assume YYE is in range.
6543 This avoids a diagnostic from gcc -Wswitch-enum.
6544 Problem reported by twlevo@xs4all.nl.
6546 * doc/bison.texinfo: Don't use "filename", as per GNU coding
6547 standards. Use "file name" or "file" or "name", depending on
6549 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
6550 not to hack/foo.tab.c.
6551 (Calc++ Top Level): 2nd arg of main is not const.
6552 * data/glr.c: b4_filename -> b4_file_name.
6553 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

6577 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
6578 All uses changed. Invoke user destructor after an error during a
6579 split parse (trivial change from Joel E. Denny).
6581 * tests/glr-regression.at
6582 (User destructor after an error during a split parse): New test case.
6583 Problem reported by Joel E. Denny in:
6584 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
6586 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6588 * README-cvs: Give URLs for recommended tools.
6589 Mention Gzip version problem, and bootstrapping issues.
6590 Remove troubleshooting section, as it's somewhat obsolete.
6592 * bootstrap (no_cache): New var, to accommodate different wget
6593 variants. Use it instead of '-C off'. Problem reported by
6596 * data/glr.c (yydestroyStackItem): New function.
6597 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
6598 debugging information. Problem reported by Joel E. Denny.

6610 Problem reported by Joel E. Denny in:
6611 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
6613 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
6615 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
6617 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
6618 lib-prefix.m4, po.m4.
6620 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
6621 in yydestruct diagnostic, since it might not be an error.
6622 Problem reported by Joel Denny near end of
6623 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6624 * data/lalr1.cc (yyerturn): Likewise.
6625 * data/yacc.c (yyreturn): Likewise.
6626 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
6628 * src/files.c: Remove obsolete FIXME comment.
6630 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
6631 with the other templates, and to fix bogus run-on messages such
6632 as the one reported at the end of
6633 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6634 All callers changed to avoid the newline.
6635 (yyprocessOneStack): Output two lines rather than one, to accommodate
6636 the above change. This changes the debug output format slightly.
6638 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
6639 reported by Joel E. Denny in
6640 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>

6647 * configure.ac (AC_INIT): Bump to 2.0c.
6649 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
6651 * NEWS: Version 2.0b.
6653 * Makefile.am (SUBDIRS): Put examples before tests, so that
6654 "make check" doesn't finish with "All 1 tests passed".
6656 * tests/regression.at (Token definitions): Don't rely on
6657 AT_PARSER_CHECK for data that contains backslashes. It currently
6658 uses 'echo', and 'echo' isn't portable if its argument contains
6659 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
6660 that the byte '\0xff' is not printable in the C locale; it is,
6661 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
6662 not printable, so use '\0x81' to test.
6664 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
6665 version of GCC, since the macro is used with non-GCC compilers.
6667 Fix core dump reported by Pablo De Napoli in
6668 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.

6670 * src/parse-gram.y (token_name): Translate type before using
6673 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
6674 the user's name space. All uses changed to __attribute__
6676 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
6677 Add __attribute__ ((__noreturn__)).
6679 * etc/clcommit: Remove. We weren't using it, and it failed
6680 "make maintainer-distcheck".
6681 * Makefile.maint: Merge from coreutils.
6682 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
6683 (syntax-check-rules): Change list of rules as described below.
6684 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

6694 Use grep -n, to make it easier to find violations.
6695 Use CVS_LIST and CVS_LIST_EXCEPT.
6696 (header_regexp, h_re): Remove.
6698 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
6699 (my-distcheck): Use more-modern GCC flags.
6700 (signatures, %.asc): Remove.
6701 (rel-files, announcement): Remove signatures.
6702 Restore old updating code, even though we don't use it, so
6703 that we're the same as coreutils.
6704 (alpha, beta, major): Depend on news-date-check.
6705 Make the upload commands.
6707 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

6716 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
6717 we comment out the Autoconf version number.
6718 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
6719 it's error-prone and "make maintainer-distcheck" rejects it.
6721 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
6722 Indent calls to "error" to pacify "make maintainer-distcheck",
6723 when the calls are not intended to be translated.
6724 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
6726 * src/Makefile.am (DEFS): Use +=, to pacify
6727 "make maintainer-distcheck".
6728 (bison_SOURCES): Add scan-skel.h.
6729 (sc_tight_scope): New rule, from coreutils.
6731 * src/files.c (src_extension, header_extension):
6732 Now static, not extern.
6733 * src/getargs.c (short_options): Likewise.
6734 * src/muscle_tab.c (muscle_table): Likewise.
6735 * src/parse-gram.y (current_class, current_type, current_prec):
6737 * src/reader.c (grammar_end, previous_rule_end): Likewise.
6738 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
6739 * src/main.c (main): Cast bindtextdomain and textdomain calls to
6740 void, to avoid warning when NLS is disabled.
6741 * src/output.c: Include scan-skel.h.
6742 (scan_skel): Remove decl, since scan-skel.h does this.
6744 Indent calls to "error" to pacify "make maintainer-distcheck".
6745 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
6746 * src/reader.h (gram_end, gram_lineno): New decls to pacify
6747 "make maintainer-distcheck".
6748 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
6749 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
6750 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
6751 (skel_lex_destroy, scan_skel): Move these decls to...
6752 * src/scan-skel.h: New file.
6753 * src/uniqstr.c (uniqstr_assert):
6754 Indent calls to "error" to pacify "make maintainer-distcheck".
6756 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
6759 * tests/torture.at: Revamp to avoid misuse of atoi that
6760 "make maintainer-distcheck" complained about.
6762 * examples/extexi (message): Don't print a message more than once,
6763 and omit line-number decoration that makes Emacs compile think
6764 that informative messages are worth worrying about.
6766 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
6768 * configure.ac: Update version number.
6770 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
6772 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
6773 autogenerated by the maintainer.
6774 * examples/calc++/.cvsignore: Add *.yy.
6776 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
6777 * lib/bitset_stats.c (bitset_stats_init): Likewise.
6778 * lib/bitsetv.c (bitsetv_alloc): Likewise.
6780 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
6782 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
6783 from maintainer-distcheck about casting the argument of 'free'.
6785 * NEWS: Mention recent yytname changes.
6786 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
6788 * bootstrap: For translations that have not yet been upgraded to
6789 the new runtime-po domain, prime the pump by extracting the
6790 relevant strings from the obsolete translations. This code can be
6791 removed once the bison-runtime domain has been translated by each
6794 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
6795 now that token names are already quoted.
6797 Fix problem reported by Anthony Heading.

6799 (yytname): Define if YYTOKEN_TABLE.
6800 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.

6805 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
6807 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
6808 again if the first call fails.

6811 (yyreportSyntaxError): Use it to dequote most string literals.
6812 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
6813 with other skeletons. All uses changed.
6814 (yytnameerr_): New function.

6820 * src/output.c (prepare_symbols): Quote all names. This undoes
6821 the 2005-04-17 change, which is now accomplished (mostly) via
6822 changes in the parsers as described above.
6823 * tests/regression.at (Token definitions, Web2c Actions):
6824 Undo most 2005-04-17 change here, too.
6826 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
6828 Fix more problems reported by twlevo@xs4all.nl.
6829 * tests/cxx-type.at: Don't pipe output of ./types through sed to
6830 remove trailing spaces. This loses the exit status of ./types,
6831 and isn't needed since ./types shouldn't be emitting trailing
6833 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
6834 as the stack isn't valid in that case.
6836 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6837 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6838 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6839 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
6841 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
6842 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
6843 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
6846 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
6847 overly-picky compilers that reject 'char *foo = "bar";'.
6849 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
6850 to FILE * parameter, not to stderr. This fixes a typo introduced
6851 in the 2005-07-12 change.
6853 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
6854 warnings from GCC 4.
6856 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
6857 (yyglrShiftDefer, yysplitStack):
6858 Remove unused parameters b4_pure_formals. All uses changed.
6859 (yyglrShift): Remove unused parameters b4_user_formals.
6861 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
6863 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
6865 Destructor cleanups and regularization among the three skeletons.
6866 * NEWS: Document the behavior changes.
6867 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
6868 stack before failing, as the cleanup code will do it for us now.
6869 * data/lalr1.cc (yyerrlab): Likewise.
6870 * data/glr.c (yyparse): Pop everything off the stack before
6871 freeing it, so that destructors get called properly.
6872 * data/lalr1.cc (yyreturn): Likewise.
6873 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
6874 This is more consistent.
6875 * doc/bison.texinfo (Destructor Decl): Mention more reasons
6876 why destructors might be called. 1.875 -> 2.1.
6877 (Destructor Decl, Decl Summary, Table of Symbols):
6878 Some English-language cleanups for %destructor.
6879 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6880 Add output line for destructor of start symbol.
6881 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
6882 because of that same extra output line.
6884 * NEWS: Document minor wording changes in diagnostics of
6885 Bison-generated parsers.
6886 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
6887 Remove unused formals. All uses changed.
6888 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
6889 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
6890 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
6891 Rename yyoverflowab to yyexhaustedlab.
6892 When memory exhaustion occurs during syntax-error reporting,
6893 report it separately rather than in a single diagnostic; this
6895 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
6896 (Memory Exhausted): Renamed from Parser Stack Overflow.
6897 Revamp wording slightly to prefer "memory exhaustion".
6898 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
6900 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
6902 Add i18n support to the GLR skeleton. Partially fix the C++
6903 skeleton; a C++ expert needs to finish this. Remove debugging
6904 msgids; there's little point to having them translated, since they
6905 can be understood only by someone who can read the
6906 (English-language) source code.
6908 Generate runtime-po/bison-runtime.pot automatically, so that we
6909 don't have to worry about garbage getting in that file. We'll
6910 make sure after the next official release that old msgids don't
6912 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
6914 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
6916 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
6917 Fix typos in explanations of the runtime file.
6918 * bootstrap: Change gettext keyword from YYI18N to YY_.
6919 Use standard Makefile.in.in in runtime-po, since we'll arrange
6920 for backward-compatible bison-runtime.po files in a different way.
6921 * data/glr.c (YY_): New macro, from yacc.c.
6922 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
6923 Translate messages intended for users.
6924 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
6925 the wording in the other skeletons. We don't know that the memory
6927 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
6928 Use same method that yacc.c uses.
6929 Don't translate debugging messages.
6930 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
6931 it doesn't work (yet), and requires C++ expertise to fix.
6932 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
6933 Move defn to a more logical place, to be consistent with other
6935 Don't translate debugging messages.
6936 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
6937 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
6938 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
6939 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
6941 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
6942 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
6944 * tests/glr-regression.at (Badly Collapsed GLR States):
6946 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6947 yylex should return 0 at EOF rather than aborting.
6949 Improve tests for stack overflow in GLR parser.
6950 Problem reported by twlevo@xs4all.nl.
6951 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
6953 (yyStackOverflow): Just longjmp, but with value 2 so that caller
6954 can handle the problem.
6955 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
6956 (yyparse): New local variable yyresult to record the result.
6957 Use result of setjmp to set it, rather than storing itinto
6959 (yyDone): Remove label.
6960 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
6961 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
6962 if YYABORT is used).
6963 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
6964 yyparse status; put status > 1 into diagnostic.
6965 Check that status==2 works.
6966 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
6967 Use exit status 3 for failure to open (which shouldn't happen).
6969 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
6971 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
6972 1 on syntax error; just let yyparse do its thing.
6973 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
6974 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
6975 (Exploding the Stack Size with Alloca):
6976 (Exploding the Stack Size with Malloc):
6977 Expect exit status 2, not 1, since the parser is supposed to blow
6978 its stack. Problem reported by twlevo@xs4all.nl.
6980 * data/glr.c (yyparse): Don't assume that the initial calls
6981 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
6982 Print a stack-overflow message and fail instead.
6983 Initialize the line-number information before creating the stack,
6984 so that the stack-overflow message can report line zero safely.
6986 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
6988 Fix problems reported by twlevo@xs4all.nl.
6989 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
6990 (yyuserMerge): Provide a default case if b4_mergers is empty.
6991 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
6992 * tests/glr-regression.at
6993 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6994 Add casts to pacify C++ compilers.
6995 * tests/glr-regression.at (Improper merging of GLR delayed action
6996 sets): Declare yylex before using it.
6997 * tests/Makefile.am (maintainer-check-g++): Fix a stray
6998 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
6999 test for valgrind; valgrind is independent of g++.
7000 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
7001 for compatibility with POSIX 1003.1-2001 (if running coreutils).
7002 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
7003 Use a destructor, so that we can expand the stack. Change
7004 YYSTYPE to char * so that we can free it. Cast result of malloc.
7006 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7008 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
7009 a valgrind failure. Problem reported by twlevo@xs4all.nl.
7011 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
7013 * PACKAGING: New file, suggested by Bruno Haible and taken from
7014 similar wording in gettext's PACKAGING file.
7015 * NEWS: Mention PACKAGING.
7016 * Makefile.am (EXTRA_DIST): Add PACKAGING.
7018 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
7020 * NEWS: Document recent i18n improvements.
7021 * bootstrap: Get runtime translations into runtime-po.
7022 Create runtime-po files automatically, if possible.
7023 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
7024 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
7025 does not infringe on the user's name space.
7026 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
7027 * doc/bison.texinfo (Internationalization): Revamp the English
7028 and Texinfo syntax a bit, to try to make it clearer.
7029 (Bison Options, Option Cross Key): Mention --print-localedir.
7030 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
7031 YYENABLE_NLS. Quote a bit more.
7032 * runtime-po/.cvsignore: New file.
7033 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
7034 * runtime-po/Rules-quot: Remove; now created by bootstrap.
7035 * runtime-po/quot.sed: Likewise.
7036 * runtime-po/boldquot.sed: Likewise.
7037 * runtime-po/en@quot.header: Likewise.
7038 * runtime-po/en@boldquot.header: Likewise.
7039 * runtime-po/insert-header.sin: Likewise.
7040 * runtime-po/remove-potcdate.sin: Likewise.
7041 * runtime-po/Makevars: Likewise.
7042 * runtime-po/LINGUAS: Likewise.
7043 * runtime-po/de.po: Likewise; we will rely on the translation project
7044 to maintain this, so "bootstrap" should get it.
7045 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
7047 * src/main.c (main): Bind the bison-runtime domain, too.
7049 2005-07-12 Bruno Haible <bruno@clisp.org>
7051 * data/yacc.c: Include <libintl.h> when NLS is enabled.
7052 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
7053 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
7054 * runtime-po: New directory.
7055 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
7056 $(DOMAIN).pot-update rule, so that old messages are never dropped.
7057 * runtime-po/Rules-quot: New file, copied from po/.
7058 * runtime-po/quot.sed: Likewise.
7059 * runtime-po/boldquot.sed: Likewise.
7060 * runtime-po/en@quot.header: Likewise.
7061 * runtime-po/en@boldquot.header: Likewise.
7062 * runtime-po/insert-header.sin: Likewise.
7063 * runtime-po/remove-potcdate.sin: Likewise.
7064 * runtime-po/Makevars: New file.
7065 * runtime-po/POTFILES.in: New file.
7066 * runtime-po/LINGUAS: New file.
7067 * runtime-po/bison-runtime.pot: New file.
7068 * runtime-po/de.po: New file.
7069 * m4/bison.m4: New file.
7070 * Makefile.am (SUBDIRS): Add runtime-po.
7071 (aclocaldir, aclocal_DATA): New variables.
7072 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
7074 * src/getargs.c (usage): Document --print-localedir option.
7075 (PRINT_LOCALEDIR_OPTION): New enum item.
7076 (long_options): Add --print-localedir option.
7077 (getargs): Handle --print-localedir option.
7078 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
7079 (Internationalization): New section.
7081 2005-07-12 Akim Demaille <akim@epita.fr>
7083 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
7084 for consistency with the rest of the code.
7085 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
7088 2005-07-12 Akim Demaille <akim@epita.fr>
7090 * src/parse-gram.y: Use %printer instead of YYPRINT.
7092 2005-07-12 Akim Demaille <akim@epita.fr>
7094 * src/symtab.h, src/symtab.c (symbol_print): New.
7095 * src/symlist.h, src/symlist.c (symbol_list_print): New.
7096 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
7098 2005-07-12 Akim Demaille <akim@epita.fr>
7100 * data/glr.c (b4_syncline): Fix (swap) the definitions of
7101 b4_at_dollar and b4_dollar_dollar.
7103 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
7105 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
7106 and Pennello's paper.
7108 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
7110 * data/yacc.c (yyparse): Undo previous patch. Instead,
7111 set yylsp[0] and yyvsp[0] only if the initial action
7112 sets yylloc and yylval, respectively.
7114 * data/yacc.c (yyparse): In the initial action, set
7115 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
7116 This avoids the use of undefined variables if the initial
7117 action does not set yylloc and/or yylval.
7119 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7121 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
7122 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
7123 Remove from CVS. These files are automatically generated.
7124 * examples/extexi: Clarify that this file is now part of Bison,
7125 not GNU M4, and that it works with any POSIX-compatible Awk.
7126 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
7127 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
7128 so that we also get calc++-parser.yy. Geneate it.
7129 Use $(AWK), not gawk, since any conforming Awk will do.
7130 Put comment before action, since older 'make' can't handle comment
7132 $(BUILT_SOURCES): List all built sources, not just some of them.
7133 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
7134 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
7135 $($(calc_sources_generated)): Remove unnecessary test for existence
7136 of target. (This had a shell syntax error anyway; a stray "x".)
7137 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
7139 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
7141 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
7142 implied by the other modules.
7144 2005-07-06 Akim Demaille <akim@epita.fr>
7146 Bind examples/calc++ to the package.

7155 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
7157 * data/glr.c (yyFail): Drastically simplify; since the format argument
7158 never had any % directives, we can simply pass it to yyerror.
7159 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
7160 be modified later, as that is the usual style in glr.c.
7161 Problems reported by Paul Hilfinger.
7163 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
7164 and size overflow errors.
7165 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
7166 in case the user prolog sets feature-test macros like _GNU_SOURCE.
7167 (YYSIZEMAX): New macro.
7168 (yystpcpy): New function, taken from yacc.c.
7169 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
7170 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
7171 so that we don't have to maintain their signatures.
7172 (yyFail): Check for buffer overflow, by using vsnprintf rather
7173 than vsprintf. Allocate a bigger buffer if possible.
7174 Report an error if buffer allocation fails.
7175 (yyStackOverflow): New function.
7176 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
7177 the initialization was successful. It might fail if storage was
7179 (yyexpandGLRStack): Add more checks for storage allocation failure.
7180 Use yyStackOverflow to report failures.
7181 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
7182 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
7183 Don't assume stack number fits in int.
7184 (yysplitStack): Check for storage allocation failure.
7185 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
7186 can print diagnostics on storage allocation failure. All callers
7188 (yyresolveValue): Use yybool for boolean.
7189 (yyreportSyntaxError): Check for size-calculation overflow.
7190 This code is taken from yacc.c.
7191 (yyparse): Check for storage allocation errors when allocating
7194 2005-07-05 Akim Demaille <akim@epita.fr>
7196 Extract calc++ from the documentation.
7197 * doc/bison.texinfo (Calc++): Add the extraction marks.
7198 * examples/extexi: New, from the aborted GNU Programming 2E.
7199 Separate the different paragraph of a file with empty lines.
7200 * examples/Makefile: Use it to extract the whole calc++ example.
7202 2005-06-24 Akim Demaille <akim@epita.fr>
7204 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
7207 2005-06-22 Akim Demaille <akim@epita.fr>
7209 * doc/bison.texinfo (C++ Language Interface): First stab.
7210 (C++ Parsers): Remove.
7212 2005-06-22 Akim Demaille <akim@epita.fr>
7214 * data/lalr1.cc (yylex_): Honor %lex-param.
7216 2005-06-22 Akim Demaille <akim@epita.fr>
7218 Start a set of simple examples.
7219 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
7220 * examples/calc++/calc++-driver.hh,
7221 * examples/calc++/calc++-parser.yy,
7222 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
7223 * examples/calc++/compile, examples/calc++/test: New.
7225 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
7227 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
7228 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
7229 which stems from the 2005-05-27 patch.
7231 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7233 * data/glr.c: Modify treatment of unused parameters to permit use
7234 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
7236 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
7238 Fix infringement on user name space reported by Janos Zoltan Szabo.
7239 * data/yacc.c (yyparse): strlen -> yystrlen.
7241 2005-05-30 Akim Demaille <akim@epita.fr>
7243 * data/lalr1.cc (_): New.
7244 Translate the various messages.
7246 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7248 Fix infringement on user name space reported by Bruno Haible.
7249 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
7250 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
7251 the user's name space.
7252 (alloca): Include <stdlib.h> to get it, if it's not built in.
7253 (YYMALLOC, YYFREE): Define only if needed.
7254 (malloc, free): Declare, but only if needed, as this infringes on
7255 the user name space.
7257 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7259 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
7260 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
7262 * lib/ebitset.c (min, max): Undef before defining.
7263 * lib/vbitset.c (min, max): Likewise.
7264 * lib/subpipe.c (create_subpipe): Save local variables in case
7265 vfork clobbers them.
7267 2005-05-24 Bruno Haible <bruno@clisp.org>
7269 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
7270 error message syntax used by gcc-4.0.
7272 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
7274 * README: Mention m4 1.4.3. Remove obsolete advice about
7275 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
7277 * bootstrap: Remove workaround for problem I encountered with
7278 gettext 0.14.1; it seems to be fixed now.
7280 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
7282 * NEWS: Version 2.0a.
7284 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
7285 the previous change.
7287 Various maintainer cleanups.
7288 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
7289 conftest*, for benefit of CVS commands run at the same time as
7290 "configure". Add build-aux, since "bootstrap" now creates it and
7292 * Makefile.cfg (move_if_change): Remove.
7293 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
7294 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
7295 (po_repo, do-po-update, po-update, wget_files, get-targets):
7296 (config.guess-url_prefix, config.sub-url_prefix):
7297 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
7298 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
7299 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
7301 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
7302 this is now the recommended name.
7303 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
7304 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
7305 ylwrap. These files now go into build-aux.
7306 * config/move-if-change: Remove.
7307 * config/prev-version.txt: Bump from 1.75 to 2.0.
7309 * bootstrap: Add stdio-safer, unistd-safer modules.
7310 Remove m4/glibc2.m4 (introduced by latest gnulib, but
7312 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
7313 fopen-safer.c, stdio-safer.h, unistd-safer.h.
7314 * lib/subpipe.c: Include "unistd-safer.h".
7315 (create_subpipe): Make sure all the newly-created
7316 file descriptors are > 2, so that diagnostics don't
7317 get sent down them (which might cause Bison to hang, in theory).
7318 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
7319 * src/files.c (xfopen): Use fopen_safer, not fopen.
7321 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
7322 yesterday's yacc.c fix.
7324 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
7326 * data/glr.c, data/lalr1.cc: Update copyright date.
7328 Fix a destructor bug reported by Wolfgang Spraul in
7329 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
7330 * data/yacc.c (yyabortlab): Don't call destructor, and
7331 don't set yychar to EMPTY.
7332 (yyoverflowlab): Don't call destructor.
7333 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
7334 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
7335 since we no longer output the message "discarding lookahead token
7338 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7340 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
7341 fix a small glitch in debugging output.
7342 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
7343 after YY_SYMBOL_PRINT where needed.
7345 (struct yyGLRState): Add some comments.
7346 (struct yySemanticOption): Add some comments.
7347 (union yyGLRStackItem): Add comment.
7349 (yymergeOptionSets): Correct this to properly perform the union,
7350 avoiding infinite reported by Michael Rosien.
7353 * tests/glr-regression.at: Add test for GLR merging error reported

7394 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
7396 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
7397 Problem reported by Ralf Menzel.
7399 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7401 * tests/actions.at: Test that stack overflow invokes destructors.
7402 From Marcus Holland-Moritz.
7403 * data/yacc.c (yyerrlab): Move the code that destroys the stack
7405 (yyreturn): to here. That way, destructors are called properly
7406 even if the stack overflows, or the user calls YYACCEPT or
7407 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
7408 (yyoverflowlab): Destroy the lookahead.
7410 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
7412 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
7414 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
7416 * NEWS: Bison-generated C parsers no longer quote literal strings
7417 associated with tokens.
7418 * src/output.c (prepare_symbols): Don't escape strings,
7419 since users don't want to see C escapes.
7420 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
7422 * tests/input.at (Torturing the Scanner): Likewise.
7423 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
7425 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
7427 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
7428 the data size is known to be too small and we can't increase it.
7429 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
7431 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
7433 * src/parse-gram.y: Include quotearg.h.
7434 (string_as_id): Quote $1 before using it as a key, since the
7435 lexer no longer quotes it for us.
7436 (string_content): Don't strip quotes, since lexer no longer
7438 * src/scan-gram.l: Include quotearg.h.
7440 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
7441 a key, since the rest of the lexer doesn't quote it.
7442 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
7443 * tests/regression.at (Token definitions): Check for backslashes
7446 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
7447 (YYSIZE_T): Define to unsigned long int when using an older compiler.
7448 (yyparse): Revamp code to generate long syntax error message, to
7449 make it easier to translate, and to avoid problems with arithmetic
7450 overflow. Change "virtual memory" to "memory" in diagnostic, since
7451 we don't know whether the memory is virtual.
7453 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7455 * NEWS: Bison-generated C parsers now use the _ macro to
7457 * data/yacc.c (_) [!defined _]: New macro.
7458 All English strings wrapped inside this macro.
7459 * doc/bison.texinfo (Bison Parser): Document _.
7460 * po/POTFILES.in: Include src/parse-gram.c, since it now
7461 includes translateable strings that parse-gram.y doesn't.
7463 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
7465 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
7466 reverting the 2004-10-11 change to this function.
7467 (symbol_check_alias_consistency): Don't call symbol_type_set
7468 if the type name is already correct.
7469 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
7471 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
7473 * tests/regression.at (Token definitions): Don't use a token named
7474 c, as that generates a "#define c ..." that runs afoul of buggy
7475 stdlib.h that uses the identifier c as a member of struct
7476 drand48_data. Problem reported by Horst Wente.
7478 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
7480 * bootstrap: Change translation URL from
7481 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
7482 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
7483 redirection glitches. Problem reported by twlevo@xs4all.nl.
7485 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
7487 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
7488 after operands; POSIX says this isn't portable for the c99 command.
7490 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
7492 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
7493 immediately if a data overrun has occurred; this may help us track
7494 down what may be a spurious failure on MacOS.
7496 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
7498 Respond to problems reported by twlevo@xs4all.nl.
7500 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
7502 * src/vcg.h: Comment fix.
7503 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
7504 (G_CMAX): Change to -1 instead of INT_MAX.
7506 * data/yacc.c (yyparse): Omit spaces before #line.
7508 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
7510 * src/tables.c (state_number_to_vector_number): Put it inside an
7511 "#if 0", since it's not currently used. Problem reported by
7514 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
7516 * src/output.c (escaped_output): Renamed from
7517 escaped_file_name_output, since we now use it for symbol tags as
7518 well. All uses changed.
7519 (symbol_destructors_output, symbol_printers_output):
7520 Escape symbol tags too.
7521 Problem reported by Matyas Forstner in
7522 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
7524 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
7526 * src/output.c (user_actions_output, token_definitions_output,
7527 symbol_destructors_output, symbol_printers_output): Likewise.
7528 * src/reader.c (prologue_augment): Likewise.
7529 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
7531 * src/vcg.c (output_edge): Don't quote linestyle arg.
7532 Problem reported by twlevo@xs4all.nl.
7534 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
7536 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
7537 example, reported by Derek M Jones. Also, make the example even
7538 more outrageous, to better illustrate how bad the problem is.
7540 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
7542 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
7543 putsym. Typo reported by Sebastian Piping.
7545 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7547 * doc/bison.texinfo (Language and Grammar): some -> same
7548 (Epilogue): int he -> in the
7549 Typos reported by Sebastian Piping via Justin Pence.
7551 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7553 * tests/glr-regression.at (Improper handling of embedded actions
7554 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
7555 embedded actions and $-N in GLR parsers", work around an Autoconf bug
7556 with dollar signs in test names.
7557 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
7558 for a similar reason.
7560 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7562 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
7563 wants to redefine G_VIEW.
7565 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
7567 * src/vcg.c (get_view_str): Remove case for normal_view.
7568 Problem reported by twlevo@xs4all.nl.
7570 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
7572 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
7573 Problem reported by twlevo@xs4all.nl.
7575 * doc/bison.texinfo: Change @dircategory from "GNU programming
7576 tools" to "Software development". Requested by Richard Stallman
7579 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
7581 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
7582 Problem reported by twlevo@xs4all.nl.
7584 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
7586 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
7587 keyword; it's not needed with modern compilers, and it doesn't
7588 affect correctness with older compilers. Suggested by
7591 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
7593 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
7594 gcc -Wswitch-default.
7595 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
7596 * data/yacc.c (yyparse): Likewise.
7598 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
7600 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
7601 already. Let config.h define any nonstandard values.
7603 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
7605 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
7606 for the benefit of slower hosts. Problem reported by
7609 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
7611 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
7612 being defined and not used.
7613 * data/lalr1.cc (yyparse): Likewise.
7614 Use "if (false)" rather than "if (0)".
7616 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
7618 * TODO: Mention that we should allow NUL bytes in tokens.
7620 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
7622 * src/scan-skel.l (<<EOF>>): Don't close standard output.
7623 Problem reported by Hans Aberg.
7625 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
7627 * src/getargs.c (version): Happy new year; update overall
7628 program copyright date from 2004 to 2005.
7630 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
7631 Problem reported by Hans Aberg.
7632 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
7633 (Output file names.): Add a test for the case when standard output
7636 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
7638 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
7639 to fix an oversight in the Bison 2.0 manual.
7641 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
7643 * NEWS: Version 2.0. Reformat the existing news items since
7644 1.875, so that related items are grouped together.
7645 * configure.ac (AC_INIT): Bump version to 2.0.
7646 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
7648 * tests/torture.at (Exploding the Stack Size with Alloca): Set
7649 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
7650 otherwise, we're not testing alloca. Unfortunately there's no
7651 simple way to consult HAVE_ALLOCA here.
7653 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
7656 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
7657 hand. This avoids a warning about comparing int to size_t when
7658 GCC warnings are enabled.
7660 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
7662 * NEWS: Bison-generated parsers no longer default to using the
7663 alloca function (when available) to extend the parser stack, due
7664 to widespread problems in unchecked stack-overflow detection.
7665 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
7666 responsibility to set it to a positive value. This lets the user
7667 specify a value that is not a preprocessor constant.
7668 * data/yacc.c (YYMAXDEPTH): Likewise.
7669 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
7670 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
7671 to be a compile-time constant. However, explain the constraints on it.
7672 Also, explain the constraints on YYINITDEPTH.
7673 (Table of Symbols): Explain that alloca is no longer the default.
7674 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
7677 * doc/bison.texinfo (Location Default Action): Mention that n must
7678 be zero when k is zero. Suggested by Frank Heckenbach.
7680 2004-12-22 Akim Demaille <akim@epita.fr>
7682 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
7683 (parser::state_type, parser::semantic_type, parser::location_type):
7684 Private, not public.
7685 (parser::parse): Return ints, not bool.
7686 Returning a bool introduces a problem: 0 corresponds to false, and
7687 it seems weird to return false on success. Returning true changes
7688 the conventions for yyparse.
7689 Alternatively we could return void and send an exception.
7690 There is no clear consensus (yet?).
7691 (state_stack, semantic_stack, location_stack): Rename as...
7692 (state_stack_type, semantic_stack_type, location_stack_type): these.
7693 Private, not public.
7694 * tests/c++.at: New.
7695 * tests/testsuite.at, tests/Makefile.am: Adjust.
7697 2004-12-21 Akim Demaille <akim@epita.fr>
7699 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
7701 2004-12-21 Akim Demaille <akim@epita.fr>
7703 Don't impose std::string for filenames.
7705 * data/lalr1.cc (b4_filename_type): New.
7706 (position::filename): Use it.
7707 (parser.hh): Move the inclusion of stack.hh and location.hh below
7708 the user code, so that needed headers for the filename type can be
7710 Forward declare them before the user code.
7711 * tests/Makefile.am (check-local, installcheck-local): Pass
7712 TESTSUITEFLAGS to the TESTSUITE.
7714 2004-12-20 Akim Demaille <akim@epita.fr>
7716 Use more STL like names: my_class instead of MyClass.
7718 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
7719 (SemanticStack, SemanticType, StateStack, StateType)
7720 (TokenNumberType, Stack, Slice, Traits, Parser::location)
7721 (Parser::value): Rename as...
7722 (location_stack, location_type, rhs_number_type, semantic_stack)
7723 (semantic_type, state_stack, state_type, token_number_type, stack)

7733 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
7735 Remove uses of 'short int' and 'unsigned short int'. This raises
7736 some arbitrary limits. It uses more memory but nowadays that's
7737 not much of an issue.
7739 This change does not affect the generated parsers; that's a different
7740 task, as some users will want to conserve memory there.
7742 Ideally we should use size_t to represent all object counts, and
7743 something like ptrdiff_t to represent signed differences of object
7744 counts; but that will require more code-cleanup than I have the
7745 time to do right now.
7747 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
7748 Use size_t, not int or short int, to count objects.

7768 2004-12-17 Akim Demaille <akim@epita.fr>
7770 * data/lalr1.cc: Extensive Doxygenation.
7771 (error_): Rename as...
7772 (error): this, since it is visible to the user.
7774 (Parser::message): Now an automatic variable from...
7775 (Parser::yyreport_syntax_error_): here.
7776 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
7778 * tests/input.at: Escape $.

7782 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
7783 Parenthesize rhs to avoid obscure problems with mistakes like
7784 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
7785 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,

7803 Use #define to handle the %name-prefix.
7805 * data/glr.c, data/yacc.c: Comment changes.
7806 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
7807 so that one can refer to yylex in the parser file, and have it
7808 renamed, as is the case with other skeletons.
7810 2004-12-16 Akim Demaille <akim@epita.fr>

7834 Fix some problems reported by twlevo at xs4all.
7835 * src/symtab.c (symbol_new): Report an error if the input grammar
7836 contains too many symbols. This is better than calling abort() later.

7838 (struct node, struct graph):
7839 Rename member expand to stretch. All uses changed.

7863 2004-12-15 Akim Demaille <akim@epita.fr>
7865 Simplify the C++ parser constructor.
7867 * data/lalr1.cc (debug_): Rename as...
7868 (yydebug_): so that the parser's internals are always in the yy*
7871 (b4_parse_param_decl): Remove the leading comma as it is now only
7872 called as unique argument list.
7873 (Parser::Parser): Remove the constructor accepting a location and
7874 an initial debugging level.
7875 Remove from the other ctor the argument for the debugging level.
7876 (debug_level_type, debug_level, set_debug_level): New.
7878 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
7881 2004-12-15 Akim Demaille <akim@epita.fr>
7883 Remove b4_root related material: failure experiment
7884 (which goal was to allow to derive from a class).
7886 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
7887 definitions and uses.
7889 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
7891 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
7892 not 2, since it's not portable to subtract 1 from the start of an
7893 array. The new item 0 is never set or used. All uses changed.
7895 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
7896 the default definition of YYLLOC_DEFAULT. Problem reported
7897 by Frank Heckenbach.
7899 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
7901 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
7902 the normal case and one for the error case. Just use the
7903 first one uniformly. Problem reported by Frank Heckenbach.
7904 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
7905 use exactly the same macro in both places.
7906 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
7907 so that the normal-case YYRHSLOC works for the error case too.
7909 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
7910 (YYLLOC_DEFAULT): Use the same macro as glr.c.
7911 * doc/bison.texinfo (Location Default Action): Don't claim that
7912 we have an array of locations. Use the same macro for both glr
7913 and lalr parsers. Mention YYRHSLOC. Mention what happens when
7916 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>

7925 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
7927 * src/scan-skel.l: Include "complain.h", for "fatal".
7929 * src/relation.h (relation_print, relation_digraph):
7930 Relation sizes are of type relation_node, not size_t (this is
7931 merely a doc fix, since the two types are equivalent).
7932 (relation_transpose): Relation sizes are of type relation_node,
7934 * src/relation.c: Likewise.
7935 (top, infinity): Now of type relation_node, not int.

7938 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
7939 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
7940 (yyparse): Remove unused local introduced in 2004-10-25 patch.
7942 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
7943 specifying whether the test should be skipped. Use it tp
7944 specify that the [%defines %skeleton "lalr1.cc"] tests currently
7945 fail on some hosts, and should be skipped.
7947 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
7949 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
7950 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
7951 unless otherwise specified below.
7953 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
7954 to allocate kernel_base, kernel_items, kernel_size, since
7955 they needn't be initialized to 0.
7956 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
7957 * src/closure.c (new_closure): Likewise, for itemset.
7958 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

7964 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
7965 * src/relation.c (relation_digraph): Likewise for VERTICES.
7966 (relation_transpose): Likewise for new_R, end_R.
7967 * src/symtab.c (symbols_token_translations_init): Likewise for
7969 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
7970 (token_actions): Likewise for yydefact, actrow, conflrow,
7972 (save_column): Likewise for froms[symno], tos[symno].
7973 (goto_actions): Likewise for state_count.
7974 (pack_table): Likewise for base, pos, check.
7975 (tables_generate): Likewise for width.
7977 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
7978 for initial core. Just have a separate core, so we needn't worry
7979 about whether kernel_size and kernel_base are initialized.
7981 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
7982 kernel_size, kernel_items): Remove unnecessary initialization.
7983 * src/conflicts.c (conflicts): Likewise.

7987 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
7988 conflrow, conflict_table, conflict_list, table, check):
7991 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
7992 This is because all callers pass unsigned int.
7993 * src/closure.h (new_closure): Likewise.
7995 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
7996 (build_relations): Initialize includes[i] in all cases.
7997 * src/reader.c (packgram): Always initialize rules[ruleno].prec
7998 and rules[ruleno].precsym. Initialize members in order.
7999 * src/relation.c (relation_transpose): Always initialize new_R[i]
8001 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
8003 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
8004 conflict_list[0] was always 0, but now it isn't initialized.
8006 * src/table.c (table_grow): When conflict_table grew, the grown
8007 area wasn't cleared. Fix this.
8009 * lib/.cvsignore: Add strdup.c, strdup.h.
8010 * m4/.cvsignore: Add strdup.m4.
8012 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
8014 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
8015 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
8016 GOTO_NUMBER_MAXIMUM, since we occasionally compute
8017 ngotos + 1 without checking for overflow.
8018 (build_relations): Use END_NODE, not -1, to denote end of edges.
8019 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
8020 build_relations): Use goto_number, not int, for goto numbers.
8021 * src/tables.c (save_column, default_goto): Likewise.
8023 2004-11-23 Akim Demaille <akim@epita.fr>
8025 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
8026 of #defining from yystype.
8027 Don't typedef yystype, C++ does not need it.
8028 This lets it possible to forward declare it as union.
8030 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
8032 * bootstrap (gnulib_modules): Add extensions.
8033 Problem reported by Jim Meyering.
8035 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
8037 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
8038 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
8039 src/system.h, src/tables.c: XFREE -> free, to accommodate
8040 recent change to gnulib xalloc.h.
8041 Problem reported by Jim Meyering.
8043 2004-11-17 Akim Demaille <akim@epita.fr>
8045 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.

8048 Alexandre Duret-Lutz <adl@gnu.org>
8050 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
8053 Use it instead of cdebug_.
8054 (Parser::debug_stream, Parser::set_debug_stream): New.
8055 (Parser::symprint_): Define cdebug_ for temporary backward
8057 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
8060 2004-11-17 Akim Demaille <akim@epita.fr>
8062 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
8063 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
8064 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
8065 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

8070 Problem reported by Frank Heckenbach.
8072 2004-10-25 Akim Demaille <akim@epita.fr>
8074 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
8075 Introduce another definition to address simple location arrays.
8076 (yyGLRStack): New member: yyerror_range.
8077 (yyrecoverSyntaxError, yyparse): Update it.
8078 (yyrecoverSyntaxError): Use it when shifting the error token to
8079 have an accurate range, equivalent to the one computed by both
8080 yacc.c and lalr1.cc.
8081 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
8082 that column numbers start at column 0, as per GNU Coding
8083 Standards, the others tests, and the doc.
8084 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
8085 Adjust to the above change (first column is 0).
8086 And adjust the location of the "<error>", now covering the whole
8089 2004-10-22 Akim Demaille <akim@epita.fr>
8090 and Paul Eggert <eggert@cs.ucla.edu>
8092 Remove some arbitrary limits on goto numbers and relations.
8093 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
8094 initial values, since they're never used.
8095 (set_goto_map): ngotos is now unsigned, so test for overflow
8096 by seeing whether it wraps around to zero.
8097 * src/lalr.h (goto_number): Now size_t, not short int.
8098 (GOTO_NUMBER_MAXIMUM): Remove.
8099 * src/relation.c (relation_print, traverse, relation_transpose):
8100 Check for END_NODE rather than looking at sign.
8101 * src/relation.h (END_NODE): New macro.
8102 (relation_node): Now size_t, not short int.
8104 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
8106 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
8107 keyword, not an identifier. Problem reported by Baron Schwartz in
8108 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
8110 2004-10-11 Akim Demaille <akim@epita.fr>
8112 * src/symtab.c (symbol_check_alias_consistency): Also check
8113 type names, destructors, and printers.
8114 Reported by Alexandre Duret-Lutz.
8115 Recode the handling of associativity and precedence in terms
8116 of symbol_precedence_set.
8117 Accept no redeclaration at all, not even equal to the previous
8119 (redeclaration): New.
8120 Use it to factor redeclaration complaints.
8121 (symbol_make_alias): Don't set the type of the alias, let
8122 symbol_check_alias_consistency do it as for other features.
8123 * src/symtab.h (symbol): Add new member prec_location, and
8125 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
8126 * tests/input.at (Incompatible Aliases): New.
8128 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
8130 .cvsignore fixes to accommodate gnulib changes,
8131 and the practice of naming build directories "_build".
8132 * .cvsignore: Add "_*". Sort.
8133 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
8134 * m4/.cvsignore: Add "*_gl.m4".
8136 2004-10-06 Akim Demaille <akim@epita.fr>
8138 * src/parse-gram.y (add_param): Fix the truncation of trailing
8141 2004-10-05 Akim Demaille <akim@epita.fr>
8143 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8144 whether the reducion was empty or not. This leaves room to
8145 improve the use of YYLLOC_DEFAULT in such a case.
8146 lalr1.cc is still experimental, so changing this is acceptable.
8147 And finally, there are probably not many users who changed the
8148 handling of locations in GLR, so changing is admissible too.
8150 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
8151 empty reduction, set @$ to an empty location ending the previously
8153 Adjust uses to make sure the code is triggered on empty
8155 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
8156 expected output: empty reductions have empty locations.
8158 2004-09-29 Akim Demaille <akim@epita.fr>
8160 * data/lalr1.cc: Move towards a more standard C++ coding style
8161 for templates: Class < T > -> Class<T>.
8163 2004-09-29 Akim Demaille <akim@epita.fr>
8165 * data/lalr1.cc: Reinstall the former ctor, for sake of
8166 compatibility, but warn it will be removed.
8167 Move towards a more standard C++ coding style (i.e., type *var ->
8170 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
8172 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
8173 since it's less likely to work if NULs are involved in the future.
8175 2004-09-27 Akim Demaille <akim@epita.fr>
8177 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
8179 2004-09-27 Akim Demaille <akim@epita.fr>
8181 * data/lalr1.cc (b4_parse_param_decl_1): New.

8186 2004-09-24 Akim Demaille <akim@epita.fr>
8188 * src/parse-gram.y (add_param): Strip the leading and trailing
8189 blanks from a formal argument declaration.
8190 (YY_LOCATION_PRINT): New.
8192 2004-09-24 Akim Demaille <akim@epita.fr>
8194 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
8197 2004-09-24 Akim Demaille <akim@epita.fr>
8199 * doc/bison.texinfo (Table of Symbols): Sort.

8203 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
8204 the useless parentheses.
8205 Suggested by Paul Eggert.
8207 2004-09-20 Akim Demaille <akim@epita.fr>
8209 Let the initial-action act on the look-ahead, and use it for the
8210 "initial push" (corresponding to an hypothetical beginning-of-file).
8211 And let lalr1.cc honor %initial-action.
8213 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
8215 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
8216 (Parser::Parser): Remove the ctor that used to initialize it.
8217 (Parser::parse): Like in the other skeletons, issue the "starting
8218 parse" message before any action.
8219 Honor %initial-action.
8220 Initialize the stacks with the lookahead.
8221 * data/yacc.c: Let $$ and @$ in %initial-action designate the
8223 Push them in the stacks.
8224 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
8226 2004-09-20 Akim Demaille <akim@epita.fr>
8228 * doc/bison.texinfo (Initial Action Decl): New.
8230 2004-09-20 Akim Demaille <akim@epita.fr>
8232 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
8233 clearer criterion to define it.
8234 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
8235 When reducing on an empty RHS, use the latest stacked location as
8237 yylloc is not always available.
8238 * data/glr.c: Likewise.
8239 Also, honor initial-actions.
8241 2004-09-20 Akim Demaille <akim@epita.fr>
8243 * data/yacc.c (YY_LOCATION_PRINT): New.
8244 Define when we know YYLTYPE's structure, i.e., when the default
8245 YYLLOC_DEFAULT is used.
8246 * data/c.m4 (b4_yysymprint_generate): Use it.
8247 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
8248 value of the result.
8249 (error_start_): Replace with...
8250 (error_range_): this location array.
8251 This allows to replace code relying on the implementation of
8252 locations by portable code.
8253 * data/yacc.c (yylerrsp): Replace with...
8254 (yyerror_range): this.
8255 Every time a token is popped, update yyerror_range[0], to have an
8256 accurate location for the error token.
8257 * data/glr.c (YY_LOCATION_PRINT): New.
8258 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
8259 deference a pointer.
8260 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
8261 report the location in %printers.
8263 * src/scan-skel.l: Instead of abort, report error messages to ease
8264 understanding skeleton scanning failures.
8266 2004-09-16 Akim Demaille <akim@epita.fr>
8268 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
8269 (iterator, const_iterator): these, to be more in the C++ spirit.
8270 Also, return reverse iterators so that when displaying the stack
8271 we display its bottom first.
8272 (Parser::stack_print_, Parser::reduce_print_): Match the messages
8274 We should probably use vector here though.
8276 2004-09-16 Akim Demaille <akim@epita.fr>
8278 Have more complete shift traces.
8280 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
8281 to report Shifts instead of ad hoc YYDPRINTF invocations,
8282 including for the error token.
8283 * data/lalr1.cc (symprint_): Output the location.
8284 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
8285 output the location within the %printer.
8286 Activate GLR tests, at least to make sure they compile properly.
8287 They still don't pass though.
8288 * tests/calc.at: Adjust expect verbose output, since now "Entering
8289 state..." is on a different line than the "Shifting" message.
8291 2004-09-08 Akim Demaille <akim@epita.fr>
8293 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
8294 Bison directive from the Bison file to the invocation of this
8295 macro, so that these directives are passed to
8296 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8297 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8298 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8299 the extra Bison directives instead of the whole series.
8300 Change the grammar so that there are recoverable errors, and
8301 unrecoverable errors. Now we can have the parser give up before
8302 consuming the whole input. As a result we now can observe that
8303 the lookahead is freed when needed.
8304 Change the parser source to parse argv[1] instead of a hard coded
8306 Simplify yylex, and give a value and location to EOF.
8307 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8308 passed directives already coded in the file.
8309 Add some tests to check the location of "error".
8310 For some tests, the C++ parser is correct, and not yacc.c.
8311 For other tests, they provide different, but unsatisfying, values,
8312 so keep the C++ value so that at least one parser is "correct"
8313 according to the test suite.
8314 (Actions after errors): Remove, this is subsumed by the
8315 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
8317 2004-09-06 Akim Demaille <akim@epita.fr>
8319 * data/lalr1.cc: Adjust the indentation of the labels.
8323 2004-09-06 Akim Demaille <akim@epita.fr>
8325 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
8326 argument, an informative message.
8327 Call YY_SYMBOL_PRINT.
8328 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
8329 * data/lalr1.cc (destruct_): Likewise.
8330 In addition, no longer depend on b4_yysymprint_generate and
8331 b4_yydestruct_generate to generate these functions, do it "by
8334 2004-09-03 Akim Demaille <akim@epita.fr>
8336 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
8337 invoked, yydestruct the lookahead.
8338 * tests/calc.at (Calculator $1): Update the expected lengths of
8339 traces: there is an added line for the discarded lookahead.
8340 * doc/bison.texinfo (Destructor Decl): Some rewording.
8341 Define "discarded" symbols.
8343 2004-09-02 Akim Demaille <akim@epita.fr>
8345 * data/lalr1.cc (translate_, destruct_): No reason to be static.
8347 2004-09-02 Akim Demaille <akim@epita.fr>
8349 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
8350 (YYDSYMPRINTF): Rename as...
8351 (YY_SYMBOL_PRINT): this.
8352 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
8354 Use it instead of direct symprint_ calls.
8355 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
8358 2004-09-02 Akim Demaille <akim@epita.fr>
8360 * data/lalr1.cc (b4_yysymprint_generate): New.
8361 (symprint_): New member function, defined when YYDEBUG.
8362 Use it consistently instead of token/nterm debugging output by
8364 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
8365 %printer calls to use cdebug_ when using lalr1.cc.
8367 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
8369 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
8370 with #ifdef YYDEBUG.
8372 2004-08-26 Akim Demaille <akim@epita.fr>
8374 * doc/bison.texinfo (Implementing Loops): Rename as...
8375 (Implementing Gotos/Loops): this.
8377 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
8379 Adjust to latest gnulib.
8380 * bootstrap (gnulib_modules): Add xalloc-die.
8381 Set LC_ALL=C so that file names sort consistently.
8382 Prefer the gnulib copies of gettext.m4, glibc21.m4,
8383 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
8384 uintmax_t.m4, ulonglong.m4.
8385 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
8386 po.m4 since we are now using _gl.m4 instead.
8388 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
8390 * src/scan-action.l: Remove. Scanning of semantic actions is
8391 handled in scan-gram.l.
8393 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
8395 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
8397 * src/location.h (struct): The file member is a uniqstr.
8398 (equal_boundaries): Use UNIQSTR_EQ for comparison.
8400 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
8402 Fix bug with non-%union parsers that have printers or destructors,
8403 which led to a Bison core dump. Reported by Peter Fales in
8404 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
8406 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
8407 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
8408 not to our own type.
8409 * src/output.c (symbol_destructors_output, symbol_printers_output):
8410 Don't assume %union.
8411 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
8412 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
8413 UNION-FLAG. All callers changed.
8414 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
8415 Use type char, not unsigned int, when declaring an array of char;
8416 this lets us remove a cast.
8417 (Printers and Destructors): Add non-%union test cases.
8419 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8421 * doc/bison.texinfo: Minor editorial changes, mostly to the new
8422 GLR writeups. E.g., avoid frenchspacing and the future tense,
8423 change "lookahead" to "look-ahead", and change "wrt" to "with
8426 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8428 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
8429 New sections, split off from the GLR Parsers section. Put the new
8430 Simple GLR Parser near the start of the GLR section, for clarity.
8431 Rewrite connective text.
8433 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
8435 * doc/bison.texinfo (Simple GLR Parsers): New section.
8437 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>

8464 * README: Update location of patched M4 distribution.
8466 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
8468 Don't assume the C++ compiler takes the same arguments as the C compiler
8470 * configure.ac (O0CXXFLAGS): New var.
8471 * tests/atlocal.in (CXXFLAGS): Use it.
8473 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>

8488 * tests/calc.at, tests/actions.at: Workaround for SGI
8489 C++ compiler. (trivial change)
8491 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
8493 Spent a few hours checking out which prerequisite versions the
8494 current sources actually require. I went all the way back to
8495 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8496 a seemingly endless set of combinations of versions more recent
8497 than that. The bottom line is that the current sources require
8498 fairly recent versions of the build tools, and it'll be some work
8500 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
8501 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
8502 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
8503 Add comments explaining why those particular versions are
8506 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
8507 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
8508 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
8510 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
8511 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
8513 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8515 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
8516 0.11.5. Suggested by Bruno Haible.
8517 * bootstrap: Remove gettext version checking.
8519 * doc/bison.texinfo (Decl Summary): Also mention that %union
8520 can depend on prerequisite types. Problem reported by Tim
8523 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8525 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
8526 * README-alpha: Don't tell people not to package this.
8528 * bootstrap: Don't assume $(...) works; use `...` instead.
8529 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
8532 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
8533 put into the -d output file, and mention what to do if YYSTYPE is
8536 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8538 Undo change made earlier today: it caused autopoint to not bring
8539 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
8542 * bootstrap: Check that gettext version matches what's in
8543 configure.ac. Warn users to ignore robots.txt ERROR 404.
8544 * bootstrap: Undo today's earlier change (logged below).
8545 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
8547 The gettext version checking is causing more trouble than it's
8548 curing; remove it. Problem reported by Paul Hilfinger.
8550 * bootstrap: Issue a warning that one can expect a message
8551 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
8552 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
8554 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
8556 Ensure that the C++ compiler used for testing actually works on a
8557 simple test program; if not, skip the C++-related tests. Problem
8558 reported by Vin Shelton in:
8559 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
8561 * m4/cxx.m4: New file.

8568 * data/glr.c (yylloc): Output this macro even if locations are not
8569 being generated, as the GLR parser needs it even in that case.
8570 Problem reported by Troy A. Johnson
8571 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
8573 * configure.ac (AC_INIT): Update to 1.875e.

8579 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
8581 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
8582 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
8583 lalr1.cc runs afoul of the first, and the last two are no longer
8584 supported by GCC 3.4.0.
8585 * README: Mention GNU m4 1.4 or later; mention m4 patches.
8586 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
8588 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
8590 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
8591 unsigned int, for compatibility with latest gnulib hash module.
8592 * src/state.c (state_hash, state_hasher): Likewise.
8593 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.

8602 character and string literals.
8603 (unexpected_end): New function.
8604 (unexpected_eof): Use it.
8605 (unexpected_newline): New function.
8606 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
8609 * NEWS: Document %expect-rr.

8612 Fix typo by replacing $1 with $option.
8613 Remove more 'intl'-related files.
8614 Don't DEFUN AM_INTL_SUBDIR twice.
8616 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
8617 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
8619 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
8620 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
8621 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
8622 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
8623 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
8624 * src/.cvsignore: Add *.output.
8626 * src/parse-gram.y: Put copyright notice inside %{ %} so it
8627 gets copied to the output file.
8629 2004-04-28 Paul Eggert <eggert@twinsun.com>
8631 Get files from the gnulib and po repositories, instead of relying
8632 on them being in our CVS. Upgrade to latest versions of gnulib
8635 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
8636 * bootstrap: Bootstrap from gnulib and po repositories.
8637 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
8638 * README-cvs: Document these changes. Remove version numbers from
8639 mentions of build tools, since they change so often. Mention Flex.
8641 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
8642 (gl_USE_SYSTEM_EXTENSIONS): Add.
8643 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
8644 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
8646 (AC_ISC_POSIX): Remove; we no longer support this
8647 ancient OS, as it gets in the way of latest Autoconf & gnulib.
8648 (AC_HEADER_STDC): Remove: we now assume C89 or better.
8649 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
8650 Do not check for C89 headers, except for locale.h which is used
8651 by the Yacc library and must port to K&R hosts.
8652 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
8653 Do not check for C89 functions, except for setlocale which is
8654 used by the Yacc library.
8655 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
8656 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
8657 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,

8659 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
8660 AM_GNU_GETTEXT): Remove; now done by:
8661 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
8662 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
8665 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
8666 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
8667 Define to empty, as gnulib.mk will do the rest for us.
8668 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
8670 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
8671 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
8673 * src/files.c: Include gnulib's xstrndup.h.
8675 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
8676 (REALLOC): Use xnrealloc, for likewise.
8677 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.

8702 Remove, as these files are now generated automatically
8703 by bootstrap or automake.
8705 * po/ChangeLog: Remove: all but one entry was a duplicate
8706 of this file, and I moved that 2000-11-02 entry here.
8708 * config/.cvsignore: Add Makefile, depcomp, install-sh.
8709 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

8729 support it. (The latest stable gzip doesn't.)
8731 2004-04-27 Paul Eggert <eggert@twinsun.com>
8733 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
8734 case, as stos_ is now used by destructors due to the 2004-02-09
8737 Remove more K&R C support.
8738 * lib/libiberty.y (PARAMS): Remove. All uses removed.

8745 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
8746 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
8747 (strchr, strspn, memchr): Remove decls.

8759 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
8761 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
8762 so that this include file can stand alone.
8763 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
8764 does this now. Include subpipe.h first after config.h, to
8765 test whether it can stand alone.
8767 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
8768 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
8771 * tests/synclines.at (%union synch line): Put a dummy member in
8772 the union, because empty unions aren't allowed in C. Caught
8775 2004-04-13 Jim Meyering <jim@meyering.net>
8777 * src/conflicts.c (conflicts_print): Correct format string typo:

8824 (declaration): Replace expected_conflicts with expected_sr_conflicts.
8825 Add %expect-rr rule.
8827 * src/scan-gram.l: Recognize %expect-rr.
8829 * src/conflicts.h (expected_sr_conflicts): Rename from
8831 (expected_rr_conflicts): Declare.
8833 * src/conflicts.c (expected_sr_conflicts): Rename from
8835 (expected_rr_conflicts): Define.
8836 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
8838 Use expected_sr_conflicts in place of expected_conflicts.
8839 Warn if expected_rr_conflicts used in non-GLR parser.
8841 * doc/bison.texinfo: Add documentation for %expect-rr.
8843 2004-03-08 Paul Eggert <eggert@gnu.org>
8845 Add support for hex token numbers. Suggested by Odd Arild Olsen in
8846 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
8848 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
8850 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
8851 * src/scan-gram.l (scan_integer): New function.
8853 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
8854 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
8855 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
8856 Say "long int", not "long", for uniformity with GNU style.
8858 2004-02-25 Paul Eggert <eggert@twinsun.com>
8860 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
8861 compilers. This fixes a problem with Intel's C++ compiler being
8862 chatty, reported by Guido Trentalancia in
8863 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
8865 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>

8875 token which are discarded.
8876 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
8877 error_start_ when erroneous token are discarded.
8878 (Parser::parse) <yyerrlab1>: Compute the location of the error
8879 token so that it covers all the discarded tokens.
8880 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
8881 it can be called with `%skeleton "lalr1.cc"', and do that.
8883 2004-02-02 Paul Eggert <eggert@twinsun.com>
8885 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
8886 $(top_srcdir)/lib and ../lib. This fixes a bug reported
8887 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
8888 There's no need to mention top_builddir since Automake does that
8890 (INCLUDES): Remove, as Automake says it's obsolescent.
8891 Contents migrated into AM_CPPFLAGS as described above.
8892 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
8894 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8896 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
8897 (yyreportSyntaxError): Handle case where lookahead token is
8900 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8902 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
8903 resulting parsers are compilable with C++.
8905 2003-12-23 Paul Eggert <eggert@twinsun.com>
8907 * config/depcomp, config/install-sh: Sync with Automake 1.8.
8908 * src/output.c (output_skeleton): Rename local var.
8909 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
8910 Bison tokens, as this runs afoul of the 2003-10-07 change that
8911 disallowed NUL bytes in character constants or string literals.
8913 * tests/local.at: Require Autoconf 2.59's Autotest.
8914 * tests/testsuite.at: Don't include local.at, since we now assume
8915 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
8917 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
8918 multiple inclusion warnings.
8920 2003-12-02 Akim Demaille <akim@epita.fr>
8922 * doc/bison.texinfo (How Can I Reset the Parser): More about start
8926 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>

8930 2003-10-07 Paul Eggert <eggert@twinsun.com>
8932 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
8933 if testsuite doesn't exist.
8935 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
8936 literals, unfortunately.
8937 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
8938 Complain about NUL bytes in character constants or string literals.
8940 2003-10-05 Paul Eggert <eggert@twinsun.com>
8942 * NEWS: Don't document %no-default-prec, as it's still
8944 * doc/bison.texinfo: Document %no-default-prec only if
8945 the defaultprec flag is set. Normally it's not.
8947 2003-10-04 Paul Eggert <eggert@twinsun.com>
8949 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
8950 non-modifiable lvalue, instead of a modifiable one.
8951 * doc/bison.texinfo (Actions): Document that $$ can
8952 be assigned to. Do not claim that $$ and $N are
8953 array element references: user code should not rely on this.
8955 2003-10-01 Paul Eggert <eggert@twinsun.com>
8957 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
8958 (grammar_declaration): Use it.

8968 * src/print_graph.c (print_graph): Adjust.
8970 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
8971 and Paul Eggert <eggert@twinsun.com>
8973 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
8974 Table of Symbols): Document %default-prec.
8975 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
8976 (grammar_declaration): Set default_prec on %default-prec.
8977 * src/scan-gram.l (%default-prec): New token.
8978 * src/reader.h (default_prec): New flag.
8979 * src/reader.c: Likewise.
8980 (packgram): Handle it.
8981 * tests/conflicts.at (%default-prec without %prec,

8987 a typo in the 2003-08-25 patch.
8989 2003-08-27 Akim Demaille <akim@epita.fr>
8991 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
8994 2003-08-26 Akim Demaille <akim@epita.fr>
8996 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
8997 "<\#" to avoid magic from Gnus when posting parts of this script.
8999 2003-08-26 Akim Demaille <akim@epita.fr>
9001 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
9002 (Parser::parse): here.
9003 Adjust: nerrs and errstatus is now replaced by...
9004 (Parser::nerrs_, Parser::errstatus_): New.
9006 2003-08-25 Akim Demaille <akim@epita.fr>
9008 * config/announce-gen, Makefile.cfg: New.
9009 * Makefile.am: Adjust.
9010 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
9011 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
9013 2003-08-25 Akim Demaille <akim@epita.fr>
9015 When reducing initial empty rules, Bison parser read an initial
9016 location that is not defined. This results in garbage, and that
9017 affects Bison's own parser. Therefore we need (i) to extend Bison
9018 to support a means to initialize this location, and (ii) to use
9019 this CVS Bison to fix CVS Bison's parser.
9021 * src/reader.h, reader.c (epilogue_augment): Remove, replace
9023 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
9024 * src/parse-gram.y: Adjust.
9025 (%initial-action): New.
9026 (%error-verbose): Since we require CVS Bison, there is no reason
9028 * src/scan-gram.l: Adjust.
9029 * src/Makefile.am (YACC): New, to make sure we use our own parser.
9030 * data/yacc.c (yyparse): Use b4_initial_action.
9032 2003-08-25 Akim Demaille <akim@epita.fr>
9034 * doc/bison.texinfo: Don't promote stdout for error messages.
9036 2003-08-25 Akim Demaille <akim@epita.fr>
9038 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
9039 From Alexandre Duret-Lutz.
9041 2003-08-25 Akim Demaille <akim@epita.fr>
9045 2003-08-25 Akim Demaille <akim@epita.fr>
9047 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
9050 2003-08-25 Akim Demaille <akim@epita.fr>
9052 * data/lalr1.cc (Parser::reduce_print_): New.
9055 2003-08-25 Akim Demaille <akim@epita.fr>
9057 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
9058 error recovery loops. This patch is based on
9059 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
9060 Also, augment the similarity between lalr1.cc and yacc.c.
9061 Note: the locations of error recovery rules are not correct yet.
9063 * data/lalr1.cc: Comment changes to augment the similarity between
9064 lalr1.cc and yacc.c.
9065 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
9066 (yyerrlab1): Remove, but where it used to be (now the bottom part of
9067 yyerrlab), when hitting EOF, pop the whole stack here instead of
9068 merely falling thru the default error handling mechanism.
9069 (yyerrorlab): New label, with the old contents of YYERROR,
9070 plus the following change: pop the stack of rhs corresponding
9071 to the production that invoked YYERROR. That is how Yacc
9072 behaves (required by POSIX).
9073 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
9076 2003-08-25 Akim Demaille <akim@epita.fr>
9078 Tune local.at so that people can "autom4te -l autotest calc.at -o
9079 calc" for instance, to extract a sub test suite.
9081 * tests/testsuite.at: Move the initialization, Autotest version
9082 requirement, and AT_TESTED invocation into...
9083 * tests/local.at: here.
9084 * tests/testsuite.at: Include it for compatibility with Autoconf
9086 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
9089 2003-08-04 Paul Eggert <eggert@twinsun.com>
9091 Rework code slightly to avoid gcc -Wtraditional warnings.
9092 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
9093 The returned value is now stored in *YY0. All callers changed.
9094 * src/output.c (merge_output): Adjust to the above change.
9096 2003-07-26 Paul Eggert <eggert@twinsun.com>
9098 * data/glr.c (YYASSERT): New macro.
9099 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
9100 yyresolveStates, yyprocessOneStack):
9101 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
9102 Derived from a suggestion by Frank Heckenbach.
9104 2003-07-25 Paul Eggert <eggert@twinsun.com>
9106 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
9107 for portability to K&R C (after ansi2knr, presumably). See
9108 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
9109 by Frank Heckenbach, though I have omitted the structure-initialization
9110 part of his glr-knr.diff patch since I recall that the Portable
9111 C Compiler didn't require that change.
9113 Let the user specify how to allocate and free memory.
9114 Derived from a suggestion by Frank Heckenbach in

9116 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
9117 All uses of free, malloc, realloc changed to use these macros,
9118 and unnecessary casts removed.
9119 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
9121 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
9123 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
9124 use s.empty() rather than s == "" to test for empty string; see
9125 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
9128 2003-06-25 Akim Demaille <akim@epita.fr>

9144 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
9145 yyreportTree): Do not assume that size_t is the same width as int,
9146 when printing sizes. Print sizes using an unsigned format.
9147 Problem reported by Frank Heckenbach in
9148 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
9150 Port to Forte Developer 7 C compiler.
9151 * data/glr.c (struct YYLTYPE): If locations are not being used,
9152 declare a single dummy member, as empty structs do not conform
9154 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
9155 the Forte Developer 7 C compiler complains that end-of-loop
9156 code is not reached.
9158 2003-06-17 Paul Eggert <eggert@twinsun.com>
9160 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
9161 avoid warnings from picky compilers about redefinition of PARAMS.
9163 2003-06-17 Paul Eggert <eggert@twinsun.com>

9171 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
9172 Don't use 'index' in comments, as it's a builtin fn on some hosts.

9174 per recent gettext manual's suggestion.
9175 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

9192 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
9193 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
9194 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
9195 * lib/vbitset.c, lib/vbitset.h: New files.
9196 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
9197 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
9200 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
9201 `How Can I Reset @code{yyparse}', since texinfo does not allow
9202 arbitrary @ in node names.
9204 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
9205 shouldn't be needed according to the gettext 0.12.1 documentation
9206 but which seem to be needed anyway: codeset.m4 glibc21.m4
9207 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
9208 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

9212 * m4/.cvsignore: Add nls.m4, po.m4.
9214 Upgrade to CVS gnulib.
9215 * stdbool_.h: File renamed from stdbool.h.in.
9216 * configure.ac (AM_STDBOOL_H): Invoke this instead of

9219 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
9220 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
9221 (MOSTLYCLEANFILES): New var.
9222 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
9223 (stdbool.h): New rule.

9229 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
9230 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
9231 the tests right now.
9232 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
9233 yyerror are declared before use; C99 requires this.
9235 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9237 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
9239 (yyrecoverSyntaxError): Correct the logic for setting and testing
9241 Correct comment on handling EOF.
9242 Allow states with only a default reduction, rather than failing
9243 (I can't quite reconstruct why these were not allowed before).
9245 Fixes to avoid problem that $-N rules in GLR parsers can cause
9246 buffer overruns, corrupting state.
9248 * src/output.c (prepare_rules): Output max_left_semantic_context
9250 * src/reader.h (max_left_semantic_context): New variable declaration.
9251 * src/scan-gram.l (max_left_semantic_context): Define.
9252 (handle_action_dollar): Update max_left_semantic_context.
9253 * data/glr.c (YYMAXLEFT): New definition.

9255 (yyresolveAction): Ditto.
9257 Fixes to problems with location handling in GLR parsers reported by
9258 Frank Heckenbach (2003/06/05).
9260 * data/glr.c (YYLTYPE): Make trivial if locations not used.
9261 (YYRHSLOC): Add parentheses, and define only if locations used.
9262 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
9264 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
9265 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
9267 * tests/cxx-type.at: Exercise location information; update tests
9268 to differentiate output with and without locations.
9269 Remove forward declarations of yylex and yyerror---caused errors
9270 because default YYLTYPE not yet defined.
9271 Change semantic actions to compute strings, rather than printing
9272 them directly (to test proper passing of semantics values). Change
9273 output to prefix notation and update test data and expected results.
9274 (yylex): Track locations.
9275 (stmtMerge): Return value rather than printing, and include arguments
9278 2003-06-03 Paul Eggert <eggert@twinsun.com>
9280 Avoid warnings generated by GCC 2.95.4 when Bison is
9281 configured with --enable-gcc-warnings.
9282 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
9283 yy::]b4_parser_class_name[::translate_,
9284 yy::Stack::operator[] (unsigned),
9285 yy::Stack::operator[] (unsigned) const,
9286 yy::Slice::operator[] (unsigned),
9287 yy::Slice::operator[] (unsigned) const):
9288 Rename local vars to avoid warnings.
9289 * tests/glr-regression.at (Improper handling of embedded actions
9290 and $-N in GLR parsers): Remove unused local variable from yylex.
9291 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
9292 (void) as arg when not pure, since we now assume C89 when building
9293 Bison. Pacify GCC by using parameter.
9295 2003-06-02 Paul Eggert <eggert@twinsun.com>
9297 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
9298 yy::Location::lines, yy::Location::columns): Rename arguments
9299 to avoid shadowing; this removes a warning generated by GCC 3.3.
9301 2003-06-01 Paul Eggert <eggert@twinsun.com>
9303 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
9304 to g++, as GCC 3.3 complains if you do it.
9305 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
9306 everything that WARNING_CFLAGS has, except omit warnings
9307 not suitable for C++.
9308 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
9309 * tests/atlocal.in (CXXFLAGS): New var.
9310 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
9312 Fix a GLR parser bug I reported in February; see
9313 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
9314 The problem was that GLR parsers did not conform to the C standard,
9315 because actions like { $1 = $2 + $3; } expanded to expressions
9316 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9317 to a local variable. The C standard says that expressions
9318 like (var = f ()) + (var = f ()) have undefined behavior.
9319 Another problem was that GCC sometimes issues warnings that
9320 yyfill and its parameters are unused.
9322 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9324 (yyfill): New function.
9326 (yyuserAction): Change type of yynormal to bool, so that it matches
9327 the new yyfill signature. Mark it as possibly unused.
9330 Follow up on a bug I reported in February, where a Bison-generated
9331 parser can loop. Provide a test case and a fix for yacc.c. I
9332 don't have a fix for lalr1.cc or for glr.c, unfortunately.
9333 The original bug report is in:
9334 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
9336 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
9337 macro's size was becoming unwieldy.
9338 (yyerrlab): Do not discard an empty lookahead symbol, as this
9339 might destroy garbage.
9340 (yyerrorlab): New label, with the old contents of YYERROR,
9341 plus the following change: pop the stack of rhs corresponding
9342 to the production that invoked YYERROR. That is how Yacc
9343 behaves, and POSIX requires this behavior.
9344 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
9345 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
9346 Define 'alarm' to do nothing if unistd.h is not available.
9347 Add a new rule "exp: '-' error;" to test the above change to
9348 data/yacc.c. Use 'alarm' to abort any test taking longer than
9349 10 seconds, as it's probably looping.
9350 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
9351 Also, the new yacc.c generates two fewer diagnostics for an
9354 2003-05-24 Paul Eggert <eggert@twinsun.com>
9356 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
9357 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
9358 This fixes a problem reported by John Bowman when the Compaq/HP
9359 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
9361 * data/yacc.c (union yyalloc): Likewise.
9362 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
9364 Switch from 'int' to 'bool' where that makes sense.
9366 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
9367 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
9368 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
9369 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
9370 Return or accept bool, not int. All callers changed.

9389 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
9390 lbitset_xor_cmp): Likewise.
9391 * lib/bbitset.h: Include <stdbool.h>.
9392 (struct bitset_vtable): The following members now return bool, not
9393 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
9394 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
9396 * src/conflicts.c (count_rr_conflicts): Likewise.

9399 * lib/ebitset.c (ebitset_obstack_init): Likewise.
9400 * lib/lbitset.c (lbitset_obstack_init): Likewise.
9401 * src/getargs.c (debug_flag, defines_flag, locations_flag,

9409 * src/reader.c (start_flag, typed): Likewise.
9410 * src/reader.h (typed): Likewise.

9423 * src/state.c (state_rule_lookaheads_print): Likewise.
9425 * config/install-sh: Sync from automake 1.7.5.
9427 2003-05-14 Paul Eggert <eggert@twinsun.com>
9429 * src/parse-gram.y (rules_or_grammar_declaration): Require a
9430 semicolon after a grammar declaration, in the interest of possible
9431 future changes to the Bison input language.
9432 Do not allow a stray semicolon at the start of the grammar.
9433 (rhses.1): Allow one or more semicolons after any rule, including
9434 just before "|" as required by POSIX.
9435 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
9438 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
9440 %parse-param support for lalr1.cc.
9442 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
9443 b4_cc_constructor_calls, b4_cc_constructor_call,
9444 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
9446 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
9447 parse-param arguments.
9448 (yy::b4_parser_class_name): Declare instance variables to
9449 hold parse-param arguments.
9450 * tests/calc.at: s/value/semantic_value/ because value clashes
9451 with a member of yy::b4_parser_class_name. Adjust C++ code
9452 to handle %parse-param. Enable %parse-param test in C++.
9454 2003-05-12 Paul Eggert <eggert@twinsun.com>
9456 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
9457 English a bit. Fix fclose typo. Change "const char" to "char
9458 const", and use ANSI C rather than K&R for "main". Suggest
9459 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
9460 and suggest yy_switch_to_buffer.
9462 2003-05-05 Paul Eggert <eggert@twinsun.com>
9464 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
9465 C89. This avoids a diagnostic on compilers that define __STDC__
9466 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
9467 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9469 2003-05-03 Paul Eggert <eggert@twinsun.com>
9471 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
9472 Do not overrun array bounds.
9473 This should fix a bug reported today by Olatunji Oluwabukunmi in
9474 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
9476 2003-04-29 Akim Demaille <akim@epita.fr>
9478 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
9479 * src/getargs.c, src/getargs.h: here, as bool, not int.
9480 (nondeterministic_parser): New.
9481 * src/parse-gram.y, src/scan-gram.l: Support
9482 %nondeterministic-parser.
9483 * src/output.c (prepare): Use nondeterministic_parser instead
9484 of glr_parser where appropriate.
9485 * src/tables.c (conflict_row, action_row, save_row)
9486 (token_actions, token_actions, pack_vector): Ditto.
9488 2003-04-29 Akim Demaille <akim@epita.fr>
9490 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
9492 2003-04-29 Akim Demaille <akim@epita.fr>
9494 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
9495 with %pure-parser and %locations to exercise the patch from Yakov
9498 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
9500 * data/yacc.c: (b4_lex_param): Corrected for the case where
9501 %lex-param is provided and %pure-parser isn't.
9503 2003-04-27 Paul Eggert <eggert@twinsun.com>
9505 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
9506 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
9507 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
9508 if it is not defined.
9509 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
9511 2003-04-26 Paul Eggert <eggert@twinsun.com>
9513 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
9514 Declare to be of type suitable for the ninf value itself, not of
9515 type suitable for the corresponding table, since the latter might
9516 be unsigned but the ninf value might be negative. This fixes a
9517 bug reported by Alexandre Duret-Lutz in
9518 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
9520 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
9521 invokes it. We shouldn't invoke it twice because it will attempt
9522 to put error.o in the archive twice. This fixes a glitch reported
9523 by Martin Mokrejs in
9524 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9526 2003-04-21 Paul Eggert <eggert@twinsun.com>
9528 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
9531 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
9533 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
9534 Fix obvious typo that results in uncompilable GLR parsers
9535 when both %pure-parser and %locations are used. (trivial change)
9537 2003-04-17 Paul Eggert <eggert@twinsun.com>
9539 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
9540 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
9541 Do not insert the expected token via unput, as this runs afoul
9542 of a POSIX-compatibility bug in flex 2.5.31.
9543 All uses changed to BEGIN the parent state,
9544 since we no longer insert the expected token via unput.
9545 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
9546 that is no longer emitted after the above change.
9548 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
9549 the first one. This change is from Paul Hilfinger, and it fixes
9550 regression reported by Werner Lemberg in
9551 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
9553 (resolve_sr_conflict): Don't invoke state_errs_set
9554 unless one or more tokens have been explicitly made errors.
9555 Otherwise, the above change causes Bison to abort.
9557 * tests/existing.at (GNU pic Grammar): New test case, taken from
9560 2003-03-31 Akim Demaille <akim@epita.fr>
9562 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
9564 2003-03-31 Akim Demaille <akim@epita.fr>
9566 * src/output.c (prepare_symbols): Avoid trailing spaces in the
9569 2003-03-31 Akim Demaille <akim@epita.fr>
9571 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
9572 From Paul Hilfinger.
9574 2003-03-29 Akim Demaille <akim@epita.fr>
9576 * m4/error.m4: Do not put under dynamic conditions some code which
9577 expansion is under static control.
9579 2003-03-29 Akim Demaille <akim@epita.fr>
9581 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
9583 2003-03-29 Akim Demaille <akim@epita.fr>
9585 * doc/bison.texinfo (Strings are Destroyed): New.
9587 2003-03-13 Paul Eggert <eggert@twinsun.com>
9589 * .cvsignore: Add configure.lineno.
9590 * src/.cvsignore: Add yacc.
9591 * tests/.cvsignore: Add testsuite.log.
9592 * doc/fdl.texi: Sync with latest FSF version.
9594 2003-03-12 Paul Eggert <eggert@twinsun.com>
9596 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
9597 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
9598 cursor, instead of leaving it undefined. This fixes a bug
9599 reported by Tim Van Holder in
9600 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
9601 * tests/input.at (Torturing the Scanner): Test the scanner on
9602 an empty input file, which was Tim Van Holder's test case.
9604 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
9605 <sys/resource.h> can be included, include sys/time.h and
9606 sys/times.h first, if available. This works around the SunOS
9607 4.1.4 porting bug reported by Bruce Becker in
9608 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
9610 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
9611 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
9614 Merge changes from gnulib. This was prompted because the CVS
9615 snapshot didn't build on Solaris 7 due to strnlen problems.
9617 These changes need to be merged back into gnulib:
9618 * lib/hash.c: Include <stdbool.h> unconditionally.
9619 * m4/onceonly.m4 (m4_quote): New macro.
9620 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
9621 Quote AC_FOREACH variable-expansions properly.
9622 The 2003-01-03 obstack.h change also needs merging.
9623 {end of changes requiring merging}
9625 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
9626 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
9627 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
9628 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
9629 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
9630 New files, imported from gnulib.
9631 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
9634 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
9635 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
9638 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
9640 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
9641 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
9642 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
9643 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
9644 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
9645 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
9646 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
9647 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
9648 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
9649 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
9650 (jm_PREREQ_ARGMATCH): Remove.
9651 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
9652 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
9654 * src/system.h: Include <stdbool.h> unconditionally.
9656 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
9657 assuming at least C89 in the bitset code for some time now.
9659 2003-03-03 Akim Demaille <akim@epita.fr>
9663 2003-03-02 Akim Demaille <akim@epita.fr>
9665 * doc/bison.texinfo (Table of Symbols): Reactivate the
9666 documentation for %lex-param, and %parse-param.
9668 2003-03-02 Akim Demaille <akim@epita.fr>
9670 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
9671 generate verbose error messages.
9672 Use the number of tokens as an upper bound in yytname, as it
9673 cannot be a non terminal.
9675 2003-03-02 Akim Demaille <akim@epita.fr>
9677 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
9680 2003-03-02 Akim Demaille <akim@epita.fr>
9682 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
9683 Use them to exercise yycheck overrun.
9684 Based on Andrew Suffield's grammar.
9686 2003-03-02 Akim Demaille <akim@epita.fr>
9688 Create tests/local.at for Bison generic testing macros.
9690 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
9691 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
9693 * tests/calc.at (AT_CHECK_CALC): Adjust.
9694 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
9695 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
9696 * tests/local.at: here.
9697 (AT_COMPILE_CXX): Tags the tests using it as c++.
9698 Ignore the test if CXX is not functional.
9700 2003-03-01 Paul Eggert <eggert@twinsun.com>
9702 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
9703 not loc->end, since loc->end might contain garbage and this leads
9704 to undefined behavior on some platforms.
9705 (id_loc, token_start): Use (IF_LINTed) initial values that do not
9706 depend on *loc, so that the reader doesn't give the the false
9707 impression that *loc is initialized.
9708 (<INITIAL>"%%"): Do not bother setting code_start, since its value
9709 does not survive the return.
9711 2003-03-01 Akim Demaille <akim@epita.fr>
9713 * src/scan-gram.l (code_start): Always initialize it when entering
9714 into yylex, as SC_EPILOGUE is activated *before* the corresponding
9715 yylex invocation. An alternative would be making it static, but
9716 then it starts with the second %%'s beginning, instead of its end.
9718 2003-02-28 Paul Eggert <eggert@twinsun.com>
9720 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
9721 around a UnixWare 7.1.1 porting bug reported by John Hughes in
9722 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
9724 2003-02-26 Paul Eggert <eggert@twinsun.com>
9726 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
9727 Remove Sequent/Pyramid discussion (nobody uses them any more).
9728 Merge VMS and MS-DOS discussion; these ports may well be dead
9729 but let's keep mentioning them for now. Put <> around email
9730 addresses. Add copyright notice.
9732 2003-02-24 Paul Eggert <eggert@twinsun.com>
9734 * data/glr.c (yy_reduce_print): yylineno -> yylno,
9735 to avoid collision with flex use of yylineno.
9736 Problem reported by Bruce Lilly in
9737 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
9738 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9739 * data/yacc.c (yy_reduce_print): Likewise.

9743 2003-02-21 Akim Demaille <akim@epita.fr>
9745 * data/lalr1.cc: Use temporary variables instead of casts to
9746 change integer types.
9747 Suggested by Paul Eggert.
9749 2003-02-21 Akim Demaille <akim@epita.fr>
9751 * doc/bison.texinfo: Use "location" consistently to refer to @n,
9752 to avoid confusions with lalr1.cc's notion of Position.
9753 Suggested by Paul Eggert.
9755 2003-02-20 Akim Demaille <akim@epita.fr>
9757 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
9758 before initial_columns.
9759 (location.hh): Use consistent variable names when defining the
9761 Use "last" so that we subtract from Positions, not from unsigned.
9763 2003-02-20 Akim Demaille <akim@epita.fr>
9765 * data/lalr1.cc (position.hh): New subfile, including the extended
9766 and Doxygen'ed documentation of class Position.
9767 (location.hh): Use it.
9768 Document a` la Doxygen.
9769 With the help of Benoit Perrot.
9771 2003-02-20 Akim Demaille <akim@epita.fr>
9773 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
9775 Redefine AT_YYERROR_SEES_LOC_IF using it.
9776 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
9778 Don't use the location in yy::Parser::error_ and
9779 yy::Parser::print_ when not %locations.
9780 Activate more lalr1.cc tests.
9782 2003-02-19 Akim Demaille <akim@epita.fr>
9784 * data/lalr1.cc: When displaying a line number, be sure to make it
9787 2003-02-19 Akim Demaille <akim@epita.fr>
9789 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
9791 (YYABORT, YYACCEPT, YYERROR): New.
9792 * tests/calc.at: Renable the lalr1.cc test.
9794 2003-02-19 Akim Demaille <akim@epita.fr>
9796 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
9797 error recovery, mixing with/without pops and discarding of the
9800 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
9802 2003-02-17 Paul Eggert <eggert@twinsun.com>
9804 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
9805 * tests/testsuite.at (AT_COMPILE): Use them.
9806 This fixes the testsuite problem reported by Robert Lentz in
9807 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
9809 2003-02-12 Paul Eggert <eggert@twinsun.com>
9811 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
9812 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
9813 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
9814 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
9815 Check for malloc failure, for consistency with yacc.c.
9816 (yytname_size): Remove, for consistency with yacc.c.
9818 The bug still remains in data/lalr1.cc, as I didn't have time
9821 2003-02-06 Akim Demaille <akim@epita.fr>
9823 * configure.ac (GXX): Rename as...
9824 (CXX): this, to keep the original Autoconf semantics.
9826 * data/lalr1.cc: Fix b4_copyright invocations.
9827 If YYDEBUG is not defined, don't depend upon name_ being defined.
9828 (location.hh): Include string and iostream.
9829 (Position::filename): New member.
9830 (Position::Position ()): New.
9831 (operator<< (Position)): New.
9832 (operator- (Position, int)): New.
9833 (Location::first, Location::last): Rename as...
9834 (Location::begin, Location::end): these, to mock the conventional
9836 (operator<< (Location)): New.
9837 * tests/atlocal.in (CXX): New.
9838 * tests/testsuite.at (AT_COMPILE_CXX): New.
9839 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
9840 locations in a more synthetic way.
9841 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
9843 Adjust the C locations to match those from Emacs: first column is
9845 Change all the expected results.
9846 Conform to the GCS: simplify the locations when applicable.
9847 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
9848 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
9849 these CPP macros with the m4 macros new defined by...
9850 (AT_CHECK_PUSHDEFS): this, i.e.:
9851 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
9852 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
9854 (AT_CHECK_POPDEFS): Undefine them.
9855 (AT_CHECK_CALC_LALR1_CC): New.
9856 Use it for the first lalr1.cc test.
9858 2003-02-04 Akim Demaille <akim@epita.fr>
9860 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
9861 Location as is defined.
9863 2003-02-04 Akim Demaille <akim@epita.fr>
9865 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
9866 name_ being defined.
9868 2003-02-03 Paul Eggert <eggert@twinsun.com>
9870 * src/gram.h (start_symbol): Remove unused decl.
9872 Use more-consistent naming conventions for local vars.
9874 * src/derives.c (derives_compute): Change type of local var from
9876 * src/gram.c (grammar_rules_partial_print): Likewise.
9877 * src/print.c (print_core): Likewise.
9878 * src/reduce.c (reduce_grammar_tables): Likewise.
9880 * src/gram.c (grammar_dump): Change name of item_number *
9881 local var from r to rp.
9882 * src/nullable.c (nullable_compute): Likewise.
9884 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
9886 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
9887 for symbol or symbol_number var.
9888 * src/reader.c (grammar_start_symbol_set): Likewise.
9889 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
9891 * src/state.c (transitions_to): Likewise.
9892 * src/state.h: Likewise.
9893 * src/tables.c (symbol_number_to_vector_number): Likewise.
9895 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
9898 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
9901 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
9904 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
9905 Use str, not s, for char * var. Use ch, not c, for character var.
9906 Use size for size var.
9908 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
9910 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
9912 * src/uniqstr.h: Likewise.
9914 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
9915 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
9916 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
9917 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
9918 param to have same name as that of enum, so that we don't use
9919 "s" to stand for a non-state.
9921 2003-02-02 Akim Demaille <akim@epita.fr>
9923 * src/scan-skel.l: Scan more than one inert character per yylex
9926 2003-02-01 Paul Eggert <eggert@twinsun.com>
9930 * po/LINGUAS: Add ms.
9932 2003-01-30 Akim Demaille <akim@epita.fr>
9934 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
9936 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9938 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
9941 Changes in response to error report by S. Eken: GLR mode does not
9942 handle negative $ indices or $ indices in embedded rules correctly.
9943 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
9945 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
9946 (b4_rhs_location): Ditto.
9947 (yyfill): New function to copy from stack tree into array
9949 (yyuserAction): Modify to allow incremental move of semantic values
9950 to rhs array when in GLR mode.
9951 Define YYFILL to use in user-defined actions to fill semantic array
9953 Remove dummy use of yystack, as there is now a guaranteed use.
9954 (yydoAction): Modify to allow incremental move of semantic values
9955 to rhs array when in GLR mode.
9956 (yyresolveAction): Ditto.
9957 (yyglrShiftDefer): Update comment.
9958 (yyresolveStates): Use X == NULL for pointers, not !X.
9959 (yyglrReduce): Ditto.
9962 * tests/glr-regr1.at: Rename to ...
9963 * tests/glr-regression.at: Add new regression test for the problems
9964 described above (adapted from S. Eken).
9965 Update copyright notice.
9966 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
9967 * tests/Makefile.am: Ditto.
9969 2003-01-28 Paul Eggert <eggert@twinsun.com>
9971 * data/lalr1.cc: Do not use @output_header_name@ unless
9972 b4_defines_flag is set. This fixes two bugs reported by
9974 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
9975 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
9977 2003-01-21 Paul Eggert <eggert@twinsun.com>
9979 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
9980 we don't need to worry about yyerrlab1 being reported as an
9981 "unused label" by non-GCC C compilers. The downside is that if
9982 locations are used then a couple of statements are duplicated each
9983 time YYERROR is invoked, but the upside is that the warnings
9985 (yyerrlab1): Move code to YERROR.
9986 (yyerrlab2): Remove. Change uses back to yyerrlab1.
9987 This reverts some of the 2002-12-27 change.
9989 2003-01-17 Paul Eggert <eggert@twinsun.com>
9991 * src/output.c (symbol_printers_output): Fix typo that led
9992 to core dump. Problem reported by Antonio Rus in
9993 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
9995 2003-01-13 Akim Demaille <akim@epita.fr>,
9996 Quoc Peyrot <chojin@lrde.epita.fr>,
9997 Robert Anisko <anisko_r@lrde.epita.fr>
9999 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
10000 when the stacks contain one element, as the loop would otherwise
10001 free the last state, and then use the top state (the one we just
10002 popped). This means that the initial elements will not be freed
10003 explicitly, as is the case in yacc.c; it is not a problem, as
10004 these elements have fake values.
10006 2003-01-11 Paul Eggert <eggert@twinsun.com>
10008 * NEWS: %expect-violations are now just warnings, reverting
10009 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
10010 bootstrapping problem reported by Matthias Klose; see
10011 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
10012 * src/conflicts.c (conflicts_print): Likewise.
10013 * tests/conflicts.at (%expect not enough, %expect too much,
10014 %expect with reduce conflicts): Likewise.
10015 * doc/bison.texinfo (Expect Decl): Document this. Also mention
10016 that the warning is enabled if the number of conflicts changes
10017 (not necessarily increases).
10019 * src/getargs.c (version): Update copyright year.
10021 2003-01-09 Akim Demaille <akim@epita.fr>
10023 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
10025 2003-01-08 Paul Eggert <eggert@twinsun.com>
10027 * Makefile.maint (WGETFLAGS):
10028 New macro, containing "-C off" to disable proxy caches.
10029 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
10030 (rel-check): Use $(WGET) instead of wget.
10032 2003-01-06 Paul Eggert <eggert@twinsun.com>
10034 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
10035 the GLR paper of Scott, Johnstone and Hussain.
10037 2003-01-04 Paul Eggert <eggert@twinsun.com>
10039 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
10040 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
10041 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
10042 (EXTRA_LIBRARIES): New var, for liby.a.
10043 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
10044 (EXTRA_SCRIPTS): New var, for yacc.
10046 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
10047 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
10048 Problem reported by Nelson H. F. Beebe.
10050 2003-01-03 Paul Eggert <eggert@twinsun.com>
10052 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
10053 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
10054 when compiling Bison 1.875's `bitset bset = obstack_alloc
10055 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
10057 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
10058 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
10059 grow to a huge size with typical invocation.
10061 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
10062 Use the pattern recommended by Autoconf 2.57, except also protect
10063 against double-definition.
10064 * src/system.h: Likewise.
10065 Portability issues reported by Nelson H. F. Beebe.
10067 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
10068 All uses changed. Provide a definition in both C and C++.
10069 (yytrue, yyfalse): Define even if defined (__cplusplus).
10071 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
10072 Reported by Nelson H. F. Beebe.
10074 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
10076 2003-01-02 Paul Eggert <eggert@twinsun.com>
10078 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
10079 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
10080 Bug reported by Nelson H. F. Beebe.
10082 2003-01-01 Paul Eggert <eggert@twinsun.com>
10086 2002-12-30 Paul Eggert <eggert@twinsun.com>
10088 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
10090 (<INITIAL>","): Here. This causes stray "," to be treated
10093 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
10094 last brace in braced code when not in Yacc mode, for compatibility
10095 with Bison 1.35. This resurrects the 2001-12-15 patch to
10098 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
10099 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
10101 2002-12-28 Paul Eggert <eggert@twinsun.com>
10103 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
10104 that of SYM's type. This fixes Debian bug 168069, reported by
10107 2002-12-28 Paul Eggert <eggert@twinsun.com>
10111 Switch back to the Yacc style of conflict reports, undoing some
10112 of the 2002-07-30 change.
10113 * doc/bison.texinfo (Understanding): Use Yacc style for
10114 conflict reports. Also, use new way of locating rules.
10115 * src/conflicts.c (conflict_report):
10116 Renamed from conflict_report_yacc, removing the old
10117 'conflict_report'. Translate the entire conflict report at once,
10118 so that we don't assume that "," has the same interpretation in
10120 (conflicts_output): Use Yacc-style conflict report for each state,
10121 instead of our more-complicated style.
10122 (conflicts_print): Use Yacc-style conflict report, except print
10123 the input file name when not emulating Yacc.
10124 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
10125 Conflicted Reduction, %expect not enough, %expect too much,
10126 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
10127 * tests/existing.at (GNU Cim Grammar): Likewise.
10128 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
10130 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
10131 fatal): Don't invoke fflush; it's not needed and it might even be
10132 harmful for stdout, as stdout might not be open.
10133 * src/reduce.c (reduce_print): Likewise.
10135 2002-12-27 Paul Eggert <eggert@twinsun.com>
10137 Fix a bug where error locations were not being recorded correctly.
10138 This problem was originally reported by Paul Hilfinger in
10139 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
10141 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10142 top of the location stack's error locations.
10143 (yyerrlab): Set it. When discarding a token, push its location
10144 onto yylerrsp so that we don't lose track of the error's end.
10145 (yyerrlab1): Now is only the target of YYERROR, so that we can
10146 properly record the location of the action that failed. For GCC
10147 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10148 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10149 (yyerrlab2): New label, which yyerrlab now falls through to.
10150 Compute the error's location by applying YYLLOC_DEFAULT to
10151 the locations of all the symbols that went into the error.
10152 * doc/bison.texinfo (Location Default Action): Mention that
10153 YYLLOC_DEFAULT is also invoked for syntax errors.
10154 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10155 Error locations include the locations of all the tokens that were
10156 discarded, not just the last token.
10158 2002-12-26 Paul Eggert <eggert@twinsun.com>
10160 * src/files.c: Include quote.h.
10161 (compute_output_file_names): Warn if we detect conflicting
10162 outputs to the same file. This should catch the misunderstanding
10163 exemplified by Debian Bug 165349, reported by Bruce Stephens..
10165 * src/conflicts.c (conflicts_print): If the user specifies
10166 "%expect N", report an error if there are any reduce/reduce
10167 conflicts. This is what the manual says should happen.
10168 This fixes Debian bug 130890, reported by Anthony DeRobertis.
10169 * tests/conflicts.at (%expect with reduce conflicts): New test.
10171 Don't use m4_include on relative file names, as it doesn't work as
10172 desired if there happens to be a file with that name under ".".
10174 * m4sugar/version.m4: Remove; it was included but it wasn't used.
10175 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
10176 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
10177 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
10178 * src/output.c (output_skeleton): Use full path names when
10179 specifying a file to include; don't rely on include path, as
10180 it's unreliable when the working file contains a file with
10183 2002-12-25 Paul Eggert <eggert@twinsun.com>
10185 Remove obsolete references to bison.simple and bison.hairy.
10186 Problem mentioned by Aubin Mahe in
10187 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
10188 * data/glr.c: Comment fix.
10189 * doc/bison.1: Remove references. Also, mention "yacc".
10191 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
10194 * src/parse-gram.y (declaration): Use enum "report_states" rather
10195 than its numeric value 1.
10197 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
10198 opening a new one. This fixes Debian bug 165349, reported by
10201 2002-12-24 Paul Eggert <eggert@twinsun.com>
10205 * Makefile.maint (cvs-update): Don't assume that the shell
10206 supports $(...), as Solaris sh doesn't.
10208 * src/parse-gram.y (lloc_default): Remove test for empty
10209 nonterminals at the end, since it didn't change the result.
10211 2002-12-24 Paul Eggert <eggert@twinsun.com>
10213 If the user does not define YYSTYPE as a macro, Bison now declares it
10214 using typedef instead of defining it as a macro. POSIX requires this.
10215 For consistency, YYLTYPE is also declared instead of defined.
10217 %union directives can now have a tag before the `{', e.g., the
10218 directive `%union foo {...}' now generates the C code
10219 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10220 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10221 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10222 instead of `yyltype'.
10224 `yystype' and `yyltype' are now obsolescent macros instead of being
10225 typedefs or tags; they are no longer documented and will be
10226 withdrawn in a future release.
10228 * data/glr.c (b4_location_type): Remove.
10229 (YYSTYPE): Renamed from yystype.
10230 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
10231 (struct YYLTYPE): Renamed from struct yyltype.
10232 (YYLTYPE): Renamed from yyltype.
10233 (yyltype, yystype): New (and obsolescent) macros,
10234 for backward compatibility.
10235 * data/yacc.c: Likewise.
10237 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10238 does not specify a union tag. This is for compatibility with
10241 * src/parse-gram.y (add_param): 2nd arg is now char * not char
10242 const *, since it is now modified by stripping surrounding { }.
10243 (current_braced_code): Remove.
10244 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
10245 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
10246 trailing " {...}". Now of type <chars>.
10247 (grammar_declaration): Adjust to bundled tokens.
10248 (code_content): Remove; stripping is now done by add_param.
10249 (print_token_value): Print contents of bundled tokens.
10250 (token_name): New function.
10252 * src/reader.h (braced_code, current_braced_code): Remove.
10253 (token_name): New decl.
10255 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
10256 token_type, not braced_code code_kind. All uses changed.
10257 (SC_PRE_CODE): New state, for scanning after a keyword that
10258 has (or usually has) an immediately-following braced code.
10259 (token_type): New local var, to keep track of which token type
10260 to return when scanning braced code.
10261 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
10262 <INITIAL>"%parse-param", <INITIAL>"%printer",
10263 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
10264 instead of returning a token type immediately.
10265 (<INITIAL>"{"): Set token type.
10266 (<SC_BRACED_CODE>"}"): Use it.
10267 (handle_action_dollar, handle_action_at): Now returns bool
10268 indicating success. Fail if ! current_rule; this prevents a core dump.
10269 (handle_symbol_code_dollar, handle_symbol_code_at):
10270 Remove; merge body into caller.
10271 (handle_dollar, handle_at): Complain in invalid contexts.
10273 * NEWS, doc/bison.texinfo: Document the above.
10274 * NEWS: Fix years and program names in copyright notice.
10276 2002-12-17 Paul Eggert <eggert@twinsun.com>
10278 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
10279 Reporting, Table of Symbols): Omit mentions of %lex-param and
10280 %parse-param from the documentation for now.
10282 2002-12-15 Paul Eggert <eggert@twinsun.com>
10284 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
10285 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10286 lookahead symbol, and which sets yychar in parser actions) and it
10287 disagreed with the Bison documentation. Bug
10288 reported by Andrew Walrond.
10290 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
10291 as the caller now does that.
10292 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
10293 (YYEMPTY): Parenthesize right hand side, since others use it.
10294 (yyparse): Don't assume that our generated code is the only code
10297 2002-12-13 Paul Eggert <eggert@twinsun.com>
10301 POSIX requires a "yacc" command.
10302 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
10303 (MOSTLYCLEANFILES): Add yacc.
10305 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
10306 as an alias for bison y.
10308 * po/LINGUAS: Add da.
10310 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
10311 problem with latest <getopt.h>.
10312 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
10314 * doc/fdl.texi: Upgrade to 1.2.
10315 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
10316 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
10317 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
10319 * config/install-sh: Sync with autotools.
10321 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
10322 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10323 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
10324 locations are requested.
10325 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
10326 locations are requested.
10328 2002-12-12 Paul Eggert <eggert@twinsun.com>
10330 Remove unportable casts and storage allocation tricks.
10331 While we're at it, remove almost all casts, since they
10332 usually aren't needed and are a sign of trouble.
10334 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
10336 * src/derives.c (derives_compute): Do not subtract NTOKENS from
10337 the pointer DSET returned by malloc; this isn't portable.
10338 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
10339 Similarly for DERIVES.
10340 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
10341 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
10342 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
10344 * src/derives.c (derives_compute): Do not bother invoking
10345 int_of_rule_number, since rule numbers are integers.
10347 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
10348 rather than XMALLOC (char, N).
10350 * src/files.c (filename_split): Rewrite to avoid cast.
10352 * src/gram.h (symbol_number_as_item_number,
10353 item_number_as_symbol_number, rule_number_as_item_number,
10354 item_number_as_rule_number):
10355 Now inline functions rather than macros, to avoid casts.
10356 * src/state.h (state_number_as_int): Likewise.
10357 * src/tables.c (state_number_to_vector_number,
10358 symbol_number_to_vector_number): Likewise.
10360 * src/gram.h (int_of_rule_number): Remove; no longer used.
10362 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
10363 since the resulting storage is always stored into.
10365 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
10368 * src/muscle_tab.c (muscle_m4_output):
10369 Now inline. Return bool, not int.
10370 * src/state.c (state_compare): Likewise.
10371 * src/symtab.c (symbol_check_defined,
10372 symbol_check_alias_consistency, symbol_pack, symbol_translation,
10373 hash_compare_symbol, hash_symbol):
10375 * src/uniqstr.c (uniqstr_print): Likewise.
10376 * src/muscle_tab.c (muscle_m4_output_processor):
10377 New function, to avoid casts.
10378 * src/state.c (state_comparator, stage_hasher): Likewise.
10379 * src/symtab.c (symbol_check_defined_processor,
10380 symbol_check_alias_consistency_processor, symbol_pack_processor,
10381 symbol_translation_processor, hash_symbol_comparator,
10382 hash_symbol_hasher): Likewise.
10383 * src/uniqstr.c (uniqstr_print_processor): Likewise.
10384 * src/muscle_tab.c (muscles_m4_output):
10385 Use new functions instead of casting old functions unportably.
10386 * src/state.c (state_hash_new): Likewise.
10387 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
10388 symbols_token_translations_init):
10390 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
10392 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
10393 var instead of casting to long, to avoid casts.
10394 (prepare_states): Use MALLOC rather than alloca, so that we don't
10395 have to worry about alloca.
10396 * src/state.c (state_hash_lookup): Likewise.
10398 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
10399 local var instead of casting to unsigned char, to avoid casts.
10401 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
10402 STATE_ALLOC): Remove.
10403 (transitions_new, errs_new, reductions_new, state_new): Use malloc
10404 rather than calloc, and use offsetof to avoid allocating slightly
10406 (state_new): Initialize all members.
10408 * src/state.c (state_hash): Use unsigned accumulator, not signed.
10410 * src/symtab.c (symbol_free): Remove; unused.
10411 (symbol_get): Remove cast in lhs of assignment.
10412 (symbols_do): Now static. Accept generic arguments, not
10413 hashing-related ones.
10415 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
10416 (symbol_processor): Remove.
10417 (symbols_do): Remove decl; now static.
10419 * src/system.h (alloca): Remove; decl no longer needed.
10420 (<stddef.h>): Include, for offsetof.
10421 (<inttypes.>, <stdint.h>): Include if available.
10422 (uintptr_t): New type, if system lacks it.
10423 (CALLOC, MALLOC, REALLOC): New macros.
10424 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these

10428 (table_grow, table_ninf_remap): Use signed table size.
10429 (save_row): Don't bother initializing locals when not needed.
10430 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
10431 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
10433 * src/vcg.h: Correct misspellings.
10435 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
10438 * src/getargs.c (getargs): Don't assume EOF == -1.
10440 2002-12-09 Paul Eggert <eggert@twinsun.com>
10442 Change identifier spellings to avoid collisions with names
10443 that are reserved by POSIX.
10445 Don't use names ending in _t, since POSIX reserves them.
10446 For consistency, remove _e and _s endings -- they're weren't
10447 needed to remove ambiguity. All uses changed.
10448 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
10449 turn was just renamed from struniq_t.
10450 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
10451 which in turn was just renamed from struniq_processor_t.
10452 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
10453 in turn was renamed from hash_compare_struniq_t.
10454 * src/LR0.c (struct state_list): Renamed from struct state_list_s.
10455 (state_list): Renamed from state_list_t.
10456 * src/assoc.h (assoc): Renamed from assoc_t.
10457 * src/conflicts.c (enum conflict_resolution): Renamed from
10458 enum conflict_resolution_e.

10522 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
10523 value_t_as_yystype -> value_as_yystype.
10525 Don't include <errno.h> in the mainstream code, since it
10526 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
10527 * lib/get-errno.c, lib/get-errno.h: New files.
10528 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
10530 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
10531 * src/output.c (output_skeleton): Likewise.
10532 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno

10538 (TAB_EXT): Renamed from EXT_TAB.
10539 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
10541 Avoid str[a-z]*, since <string.h> reserves that name space.
10542 Change all instances of "struniq" in names to "uniqstr", and
10543 likewise for "STRUNIQ" and "UNIQSTR".
10544 * src/uniqstr.c: Renamed from src/struniq.c.
10545 * src/uniqstr.h: Renamed from src/struniq.h.
10546 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
10547 * src/files.c (strsuffix): Remove; unused.
10548 (concat2): Renamed from stringappend. Now static.
10549 * src/files.h (strsuffix, stringappend): Remove; unused.
10550 * src/parse-gram.y (<chars>): Renamed from <string>.
10551 (<uniqstr>): Renamed from <struniq>.

10556 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
10557 (N_EXPAND): Renamed from N_STRETCH.

10561 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
10563 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.

10565 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.
10566 * src/tables.c (VECTOR_NUMBER_MAX, VECTOR_NUMBER_MIN): Remove; unused.
10567 (BASE_MAXIMUM): Renamed from BASE_MAX.
10568 (BASE_MINIMUM): Renamed from BASE_MIN.
10569 (ACTION_MAX): Remove; unused.
10570 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
10571 Unnecessary casts removed from above defines.
10574 Fix misspelling in names.
10575 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
10576 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
10580 * lib/timevar.c (timevar_report): Renamed from time_report,
10581 for consistency with other names.
10582 * lib/timevar.h (timevar_report): New decl.
10583 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
10586 Sort include-file uses.
10588 Reorder all include files under src to be in the order "system.h".
10589 then the ../lib include files in angle brackets (alphabetized),
10590 then the . include files in double-quotes (alphabetized). Fix
10591 dependency breakages encountered in this process, as follows:
10592 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
10593 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
10594 * src/state.h: Include "symtab.h".
10596 2002-12-08 Paul Eggert <eggert@twinsun.com>
10598 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
10599 since this causes problems when __file__ contains character
10600 sequences like "@" that are treated specially by src/scan-skel.l.
10601 Instead, just use the file's basename. This fixes the bug
10602 reported by Martin Mokrejs in
10603 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
10605 2002-12-06 Paul Eggert <eggert@twinsun.com>
10607 Add support for rules that do not have trailing semicolons, as
10608 POSIX requires. Improve the quality of locations in Bison
10611 * src/location.c: Include <quotearg.h>.
10612 (empty_location): Now const.
10613 (location_print): New function. Follow the recommendation of the
10614 GNU Coding Standards for locations that span file boundaries.
10615 * src/location.h: Do not include <quotearg.h>; no longer needed.
10616 (boundary): New type.
10617 (location_t): Use it. This allows locations to span file boundaries.
10618 All member uses changed: file -> start.file or end.file (as needed),
10619 first_line -> start.line, first_column -> start.column,
10620 last_line -> end.line, last_column -> end.column.
10621 (equal_boundaries): New function.
10622 (LOCATION_RESET, LOCATION_STEP): Remove.
10623 (LOCATION_PRINT): Remove. All callers changed to use location_print.
10624 (empty_location): Now const.
10625 (location_print): New decl.
10626 * src/parse-gram.y (lloc_default): New function, which handles
10627 empty locations more accurately.
10628 (YYLLOC_DEFAULT): Use it.
10629 (%token COLON): Remove.
10630 (%token ID_COLON): New token.
10632 (declarations, rules): Remove trailing semicolon.
10633 (declaration, rules_or_grammar_declaration):
10634 Allow empty (";") declaration.
10635 (symbol_def): Remove empty actions; no longer needed.
10636 (rules_or_grammar_declaration): Remove trailing semicolon.
10637 (semi_colon.opt): Remove.
10638 * src/reader.h: Include location.h.
10639 (scanner_cursor): New decl.
10640 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
10642 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
10644 (STEP): Remove. No longer needed, now that adjust_location does
10645 the work. All uses removed.
10646 (scanner_cursor): New var.
10647 (adjust_location): Renamed from extend_location. It now sets
10648 *loc and adjusts the scanner cursor. All uses changed.
10649 Don't bother testing for CR.
10650 (handle_syncline): Remove location arg; now updates scanner cursor.
10651 All callers changed.
10652 (unexpected_end_of_file): Now accepts start boundary of token or
10653 comment, not location. All callers changed. Update scanner cursor,
10655 (SC_AFTER_IDENTIFIER): New state.
10656 (context_state): Renamed from c_context. All uses changed.
10657 (id_loc, code_start, token_start): New local vars.
10658 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
10659 processing of Yacc white space and equivalents here.
10660 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
10661 instead of returning ID immediately, since we need to search for
10662 a subsequent colon.
10663 (<INITIAL>"'", "\""): Save token_start.
10664 (<INITIAL>"%{", "{", "%%"): Save code_start.
10665 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
10666 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
10667 BEGIN context_state at end, not INITIAL.
10668 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
10669 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
10670 Return correct token start.
10671 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
10672 the start of a character, string or multiline comment is found.
10673 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
10674 Reduction): Adjust reported locations to match the more-precise
10675 results now expected.
10676 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
10677 * tests/reduce.at (Useless Rules, Reduced Automaton,
10678 Underivable Rules): Likewise.
10679 * tests/regression.at (Invalid inputs): No longer `expecting ";"
10680 or "|"' now that so many other tokens are allowed by the new grammar.
10682 * src/complain.h (current_file): Remove duplicate decl;
10683 current_file is now owned by files.h.
10684 * src/complain.c, src/scan-gram.l: Include files.h.
10686 2002-12-06 Paul Eggert <eggert@twinsun.com>
10688 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
10689 promotes to int; it might be unsigned int.
10690 * data/yacc.c (yy_reduce_print): Likewise.
10692 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
10693 be #defined in the prologue, not in the Bison declarations.
10694 This fixes Debian Bug 102878, reported by Shaul Karl.
10696 2002-12-02 Paul Eggert <eggert@twinsun.com>
10698 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
10699 * lib/strtoul.c: New file, from gnulib.
10700 This fixes a porting bug reported by Peter Klein in
10701 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
10703 2002-11-30 Paul Eggert <eggert@twinsun.com>
10705 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
10706 and put only a forward declaration in the prologue. This is for
10707 consistency with the other scanner helper functions.
10709 Type clashes now generate warnings, not errors, since it
10710 appears that POSIX may allow some grammars with type clashes.
10711 * src/reader.c (grammar_current_rule_check): Warn about
10712 type clashes instead of complaining.
10713 * tests/input.at (Type Clashes): Expect warnings, not complaints.
10715 Add Yacc library, since POSIX requires it.
10716 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
10717 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
10718 * lib/main.c, lib/yyerror.c: New files.
10720 gram_error can be static; it need not be extern.
10721 * src/reader.h (gram_error): Remove decl.
10722 * src/parse-gram.y (gram_error): Now static. Add static decl.
10723 (print_token_value): Omit parameter names from forward decl,
10726 2002-11-29 Paul Eggert <eggert@twinsun.com>
10728 * doc/bison.texinfo: Emphasize that yylex and yyerror must
10729 be declared before being used. E.g., one should typically
10730 declare them in the prologue. Use GNU coding style in examples.
10731 Put "const" consistently after the type it modifies. Mention
10732 that C99 supports "inline". Mention that yyerror traditionally
10735 %parse-param and %lex-param now take just one argument, the
10736 declaration; the argument name is deduced from the declaration.
10738 * doc/bison.texinfo (Parser Function, Pure Calling, Error
10739 Reporting, Table of Symbols): Document this.
10740 * src/parse-gram.y (add_param): New function.
10742 (declaration): Implement new rule for %parse-param and %lex-param.
10743 * src/scan-gram.l: "," now elicits a warning, rather than being
10744 a token; this is more compatible with byacc.
10745 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
10747 2002-11-27 Paul Eggert <eggert@twinsun.com>
10749 Rename identifiers to avoid real and potential collisions.
10751 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
10752 to avoid collision with lex macro described by Bruce Lilly in
10753 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10754 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10755 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
10756 * src/parse-gram.y (print_token_value): Renamed from yyprint.
10758 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
10759 The name "yycontrol" violates the name space rules, and this stuff
10760 wasn't being used anyway.
10761 (input): Remove action; this stuff wasn't being used.
10762 (gram_error): Rename local variable yylloc -> loc.
10763 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
10764 (YY_DECL): Don't use "yy" at start of local variables.
10765 All uses changed, e.g., yylloc -> loc.
10766 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
10767 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
10768 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
10769 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
10771 * src/parse-gram.y (gram_error): loc is now const *.
10772 * src/reader.h (gram_error): Likewise.
10774 2002-11-24 Paul Eggert <eggert@twinsun.com>
10778 * tests/actions.at (Actions after errors): Use an output format
10779 more similar to that of the Printers and Destructors test.
10780 Test the position of the ';' token too.
10781 (Printers and Destructors): Likewise.
10782 (Printers and Destructors: %glr-parser): Remove for now, to avoid
10783 unnecessarily alarming people when the test fails.
10785 * data/yacc.c (yyerrlab1): Move this label down, so that the
10786 parser does not discard the lookahead token if the user code
10787 invokes YYERROR. This change is required for POSIX conformance.
10789 * lib/error.c: Sync with gnulib.
10791 2002-11-22 Paul Eggert <eggert@twinsun.com>
10793 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
10794 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
10795 * lib/xmalloc.c: Likewise.
10797 2002-11-20 Paul Eggert <eggert@twinsun.com>
10799 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
10801 2002-11-20 Paul Eggert <eggert@twinsun.com>
10803 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
10804 should use `if (! x) abort ();' rather than `assert (x);', and
10805 anyway it's one less thing to worry about configuring.
10807 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
10808 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
10809 and replace all instances of assert with abort.
10810 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
10811 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
10813 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
10814 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
10815 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
10816 hash_find_entry, hash_rehash, hash_insert): Likewise.
10817 * src/conflicts.c (resolve_sr_conflict): Likewise.
10818 * src/lalr.c (set_goto_map, map_goto): Likewise.
10819 * src/nullable.c (nullable_compute): Likewise.
10820 * src/output.c (prepare_rules, token_definitions_output): Likewise.
10821 * src/reader.c (packgram, reader): Likewise.
10822 * src/state.c (state_new, state_free, state_transitions_set,
10823 state_reduction_find): Likewise.
10824 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
10825 symbol_pack): Likewise.
10826 * src/tables.c (conflict_row, pack_vector): Likewise.
10827 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10828 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10829 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
10830 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
10832 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
10833 (ARGMATCH_CONSTRAINT): New macro.
10834 (ARGMATCH_ASSERT): Use it.
10836 * src/system.h (verify): New macro.
10837 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
10838 rather than assert.
10839 * src/tables.c (tables_generate): Likewise.
10841 * src/struniq.c (struniq_assert): Now returns void, and aborts
10842 if the assertion is false.
10843 (struniq_assert_p): Remove.
10844 * src/struniq.h: Likewise.
10846 2002-11-18 Paul Eggert <eggert@twinsun.com>
10848 * data/glr.c (yygetLRActions): Replace `yyindex' with
10849 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
10850 This fixes the regression with Sun ONE Studio 7 cc that I reported in
10851 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
10853 2002-11-18 Akim Demaille <akim@epita.fr>
10855 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
10857 From Tim Van Holder.
10859 2002-11-17 Paul Eggert <eggert@twinsun.com>
10861 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
10862 to "SyntaxError" for consistency with my 2002-11-15 change.
10864 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
10865 not define to {}, since this breaks the common use of `YYDPRINTF
10866 ((...));' if a single statement is desired (e.g. before `else').
10867 Work around GCC warnings by surrounding corresponding calls with
10869 (yyhasResolvedValue): Remove unused function.
10870 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
10872 (yyreportSyntaxError): Renamed from yyreportParseError.
10873 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
10875 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
10876 extern when possible. Remove unused initializations.
10878 2002-11-16 Akim Demaille <akim@epita.fr>
10880 Augment the similarity between GLR and LALR traces.
10882 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
10883 (YY_REDUCE_PRINT): New.
10884 (yyparse): Use them.
10885 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
10887 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
10888 state reached after the reduction/recovery, since...
10889 (yyparse, yyprocessOneStack): Report the state we are entering in.
10891 2002-11-16 Akim Demaille <akim@epita.fr>
10893 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
10894 Add support for --trace=skeleton.
10895 * src/scan-skel.l: %option debug.
10896 Scan strings of non-@ or \n instead of character by character.
10897 (scan_skel): Handle trace_skeleton.
10899 (@output_parser_name@, @output_header_name@): ``Restore'' their
10900 support (used to be M4 macros).
10901 * data/yacc.c: Quote larger chunks, a la glr.c.
10902 * data/lalr1.cc: Likewise.
10903 The header guards are no longer available, so use some other
10904 string than `YYLSP_NEEDED'.
10906 2002-11-16 Akim Demaille <akim@epita.fr>
10908 Make the ``Printers and Destructors'' test more verbose, taking
10909 `yacc.c''s behavior as (possibly wrong) reference.
10911 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
10912 instead of fprint on stdout.
10913 Set and report the last_line of the symbols.
10914 Consistently display values and locations.
10916 2002-11-16 Paul Eggert <eggert@twinsun.com>
10918 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
10920 2002-11-15 Paul Eggert <eggert@twinsun.com>
10922 * tests/actions.at (Actions after errors): New test case.
10924 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
10925 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
10926 tests/action.at, tests/calc.at, tests/conflicts.at,
10927 tests/cxx-type.at, tests/regression.at:
10928 "parse error" -> "syntax error" for POSIX compatibility.
10929 "parsing stack overflow..." -> "parser stack overflow" so
10930 that code matches Bison documentation.
10932 2002-11-15 Akim Demaille <akim@epita.fr>
10934 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
10935 take two BRACED_CODE, not two string_content.
10936 Free the scanner's obstack when we are done.
10937 (code_content): New.
10938 * tests/calc.at: Adjust.
10939 * doc/bison.texinfo: Adjust.
10940 Also, make sure to include the `,' for these declarations.
10942 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
10944 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
10945 definition; avoids potential autoreconf problems.
10947 2002-11-15 Akim Demaille <akim@epita.fr>
10949 Always check the value returned by yyparse.
10951 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
10952 returned by yyparse.
10953 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.

10956 returned by yyparse.
10958 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10960 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
10963 2002-11-14 Paul Eggert <eggert@twinsun.com>
10965 * src/output.c (output_skeleton): Call xfopen instead of
10966 duplicating xfopen's body.
10968 Fix bugs reported by Nelson H. F. Beebe in
10969 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
10971 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
10972 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
10973 Group compiler. Instead, use "$CC -E bar.c". Include the .h
10974 file twice in the grammar, as an extra check.
10976 * tests/input.at (Torturing the Scanner): Surround the
10977 backslash-newline tests with "#if 0", to make it less likely that
10978 we'll run into compiler bugs. Bring back solitary \ inside
10979 comment, but add a closing comment to work around HP C bug. Don't
10980 test backslash-newline in C character constant.
10982 2002-11-14 Akim Demaille <akim@epita.fr>
10984 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
10985 status of the compiler.
10986 Calling `exit 1' is no longer needed.
10987 Reported by Nelson H. F. Beebe.
10989 2002-11-14 Akim Demaille <akim@epita.fr>
10991 * tests/atlocal.in (CPPFLAGS): We have config.h.
10992 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
10994 * tests/actions.at, tests/calc.at, tests/conflicts.at,
10995 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
10996 * tests/regression.at, tests/torture.at: Use them for all the
10997 grammars that are to be compiled.
10998 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
10999 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
11000 * doc/bison.texinfo (GLR Parsers): Document `inline'.
11002 2002-11-14 Akim Demaille <akim@epita.fr>
11004 * doc/bison.texinfo: Various formatting changes (alignments in
11005 samples, additional @group/@end group, GCS in samples.
11006 Use @deffn instead of simple @table to define the directives,
11007 macros, variables etc.
11009 2002-11-13 Paul Eggert <eggert@twinsun.com>
11011 Fix some bugs reported by Albert Chin-A-Young in
11012 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
11014 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
11015 -o c"; the HP C compiler chatters during compilation.
11016 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
11017 * tests/headers.at (export YYLTYPE): Likewise.
11019 * tests/input.at (Torturing the Scanner): Remove lines containing
11020 solitary backslashes, as they tickle a bug in the HP C compiler.
11022 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
11023 comments, since they're not portable. Use GNU coding style.
11025 2002-11-13 Akim Demaille <akim@epita.fr>
11027 * data/yacc.c: Leave bigger chunks of quoted text.
11028 (YYDSYMPRINTF): New.
11029 Use it to report symbol activities.

11037 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
11038 (yyglrReduce): Return yyok, not 0.
11039 This should avoid the enumerated-type warnings reported
11040 by Nelson H. F. Beebe in
11041 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
11043 * lib/bbitset.h (BITSET_INLINE): Remove.
11044 * lib/bitset.h [! BITSET_INLINE]: Remove.
11045 (bitset_set, bitset_reset, bitset_test): Rename local vars
11046 to avoid shadowing warnings by GCC.
11048 * data/glr.c (inline): Remove #define. It's the user's
11049 responsibility to #define it away, just like 'const'.
11050 This fixes one of the bugs reported by Nelson H. F. Beebe in
11051 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
11053 * Makefile.maint (po-check): Scan .l and .y files instead of the
11054 .c and the .h files that they generate. This fixes the bug
11055 reported by Tim Van Holder in:
11056 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
11057 Look for N_ as well as for _. Try to avoid matching #define for
11059 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
11060 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
11061 * src/scan-gram.l: Revamp regular expressions so that " and '
11062 do not confuse xgettext.
11064 * src/struniq.h (struniq_new): Do not declare the return type
11065 to be 'const'; this violates the C standard.
11066 * src/struniq.c (struniq_new): Likewise.
11068 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
11070 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
11071 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
11074 2002-11-12 Akim Demaille <akim@epita.fr>
11076 * Makefile.maint: Sync with Autoconf:
11077 (local_updates): New.
11079 2002-11-12 Akim Demaille <akim@epita.fr>
11081 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
11083 2002-11-12 Akim Demaille <akim@epita.fr>
11085 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the

11093 2002-11-12 Akim Demaille <akim@epita.fr>
11095 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
11096 Use it to test the GLR parser.
11098 2002-11-12 Akim Demaille <akim@epita.fr>
11100 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
11102 * data/glr.c (yystos): New.
11103 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
11104 (YYDSYMPRINT): New.
11105 (yyval): Don't define it, it is handled via M4.
11106 (yyrecoverParseError): Free verbosely the discarded symbols.
11107 * data/yacc.c (yysymprint): Remove, rather...
11108 (b4_yysymprint_generate): invoke.
11109 * data/c.m4 (b4_yysymprint_generate): New.
11110 Accept pointers as arguments, as opposed to the version from
11112 (b4_yydestruct_generate): Likewise.
11113 * tests/cations.at (Printers and Destructors): Use Bison directives
11114 instead of CPP macros.
11115 Don't rely on internal details.
11117 2002-11-12 Akim Demaille <akim@epita.fr>
11119 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
11120 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
11121 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
11122 it against YYEMPTY and so forth), work on yytoken (i.e., set
11123 it to YYEMPTY etc.).
11124 (yydestruct): Replace with a b4_yydestruct_generate invocation.
11125 (b4_symbol_actions): Remove.
11126 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
11127 for 0, end-of-input.
11129 2002-11-12 Akim Demaille <akim@epita.fr>
11131 * doc/bison.texinfo (Destructor Decl): New.
11133 2002-11-12 Akim Demaille <akim@epita.fr>
11135 * src/tables.c (tables_generate): Use free for pointers that
11136 cannot be NULL, not XFREE.
11137 (pack_vector): Use assert, not fatal, for bound violations.
11138 * src/state.c (state_new): Likewise.
11139 * src/reader.c (reader): Likewise.
11140 * src/lalr.c (set_goto_map): Likewise.
11141 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
11144 2002-11-12 Akim Demaille <akim@epita.fr>
11146 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
11148 * src/scan-gram.l (last_string): Is global to the file, not to
11150 * src/parse-gram.y (input): Don't append the epilogue here,
11151 (epilogue.opt): do it here, and free the scanner's obstack.
11152 * src/reader.c (epilogue_set): Rename as...
11153 (epilogue_augment): this.
11154 * data/c.m4 (b4_epilogue): Defaults to empty.
11156 2002-11-12 Akim Demaille <akim@epita.fr>
11158 * src/getargs.c (long_options): Remove duplicates.

11166 * src/struniq.h, src/struniq.c (struniq_t): Is const.
11167 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
11169 Use struniq for symbols.
11171 * src/symtab.h (symbol_t): The tag member is a struniq.
11172 (symbol_type_set): Adjust.
11173 * src/symtab.c (symbol_new): Takes a struniq.

11182 and type members are struniqs.
11183 * src/reader.c (get_merge_function)
11184 (grammar_current_rule_merge_set): Adjust.
11185 (TYPE, current_type): Are struniq.
11187 Use struniq for file names.
11189 * src/files.h, src/files.c (infile): Split into...
11190 (grammar_file, current_file): these.
11191 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.

11197 Don't free the input file name.
11199 2002-11-12 Akim Demaille <akim@epita.fr>
11201 * src/symtab.c (symbol_free): Remove dead deactivated code:

11212 2002-11-11 Paul Eggert <eggert@twinsun.com>
11214 Revamp to fix many (but not all) of the C- and M4-related quoting
11215 problems. Among other things, this fixes the Bison bug reported
11216 by Jan Hubicka when processing the Bash grammar; see:
11217 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
11219 Use new @ escapes consistently. Represent brackets with @{ and @}
11220 rather than @<:@ and @:>@, since this works a bit better with dumb
11221 editors like vi. Represent @ with @@, since @ is now consistently
11222 an escape. Use @oline@ and @ofile@ rather than __oline__ and
11223 __ofile__, to avoid unexpected expansions. Similarly, use @output
11224 rather than #output.
11226 * data/c.m4 (b4_copyright): Omit file name from comment, since
11227 the file name could contain "*/".
11228 (b4_synclines_flag): Don't quote the 2nd argument; it should already
11229 be quoted. All uses changed.
11231 * data/glr.c: Use new @ escapes consistently.
11232 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
11233 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
11234 Remove, since they couldn't handle arbitrary characters in file
11236 * data/lalr1.cc: Likewise.
11237 * data/yacc.c: Likewise.
11239 * src/files.c (output_infix): Remove; all uses removed.
11240 * src/files.h: Likewise.
11242 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
11243 mishandled funny characters in file names, and anyway it isn't
11245 * data/yacc.c: Likewise.
11246 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
11248 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
11249 * data/yacc.c: Likewise.
11251 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
11253 (muscle_init): Quote filename as a C string.
11254 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
11255 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
11256 * src/output.c (escaped_file_name_output): New function.
11257 (prepare_symbols): Quote tokens for M4.
11258 (prepare): Don't insert output_infix, output_prefix,
11259 output_parser_name, output_header_name; this is now down by scan-skel.
11260 Insert skeleton as a C string.
11262 * src/output.c (user_actions_output, symbol_destructors_output,
11263 symbol_printers_output): Quote filenames for C and M4.
11264 * src/reader.c (prologue_augment, epilogue_set): Likewise.
11266 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
11267 escapes other than \\ and \'; this simplifies the code.
11268 (<SC_STRING>): Likewise, for \\ and \".
11269 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
11270 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
11271 Use new escapes @{ and @} for [ and ].
11273 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11274 them with auto vars.
11275 Switch to new escape scheme, where @ is the escape character uniformly.
11276 Abort if a stray escape character is found. Avoid unbounded input
11277 buffer when parsing non-escaped text.
11279 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
11280 __oline__, #output, $@, and @{ do not have unintended meanings.
11282 2002-11-09 Paul Eggert <eggert@twinsun.com>
11284 Fix the test failure due to GCC warnings described in
11285 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
11286 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
11287 evaluate to 0 if it's impossible for NINF to be in the respective
11289 (yygetLRActions, yyrecoverParseError): Use them.
11291 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
11292 counted in the token inserted at end of file. Now takes
11293 location_t *, not location_t, so that the location can be
11294 adjusted. All uses changed.
11296 * tests/regression.at (Invalid inputs): Adjust wording in
11297 diagnostic to match the new behavior.
11299 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
11300 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
11301 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
11302 abort ();'. This reduces the runtime of the "Many lookaheads"
11303 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
11306 2002-11-07 Paul Eggert <eggert@twinsun.com>
11308 * src/parse-gram.y (CHARACTER): Remove unused token.
11311 * src/scan-gram.l: Remove stack option. We no longer use the
11312 stack, since the stack was never deeper than 1; instead, use the
11313 new auto var c_context to record the stacked value.
11315 Remove nounput option. At an unexpected end of file, we now unput
11316 the minimal input necessary to end cleanly; this simplifies the
11319 Avoid unbounded token sizes where this is easy.
11321 (unexpected_end_of_file): New function.
11322 Use it to systematize the error message on unexpected EOF.
11323 (last-string): Now auto, not static.
11324 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
11325 (scanner_last_string_free): Remove; not used.
11326 (percent_percent_count): Move decl to just before use.
11327 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
11328 not the (never otherwised-used) CHARACTER.
11330 2002-11-07 Akim Demaille <akim@epita.fr>
11332 Let yyerror always receive the msg as last argument, so that
11333 yyerror can be variadic.
11335 * data/yacc.c (b4_yyerror_args): New.
11336 Use it when calling yyerror.
11337 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
11338 Use it when calling yyerror.
11339 * doc/bison.texinfo (Error Reporting): Adjust.
11340 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
11341 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
11343 2002-11-06 Akim Demaille <akim@epita.fr>
11345 #line should have quoted strings.
11346 Ideally, this should be done by m4_quotearg.
11348 * src/scan-skel.l: Include quotearg.h.
11350 * src/output.c (symbol_printers_output)
11351 (symbol_destructors_output): Quote the file name.
11353 2002-11-06 Akim Demaille <akim@epita.fr>
11355 * tests/regression.at (Invalid inputs): Adjust to the recent
11358 2002-11-06 Akim Demaille <akim@epita.fr>
11360 Restore --no-lines.
11361 Reported by Jim Kent.

11387 * src/scan-gram.l: Use more accurate diagnostics, e.g.
11388 "integer out of range" rather than "invalid value".
11389 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
11392 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
11393 Also, remove one static variable in the scanner.
11395 * src/scan-gram.l (braces_level): Now auto, not static.
11396 Initialize to zero if the compiler is being picky.
11397 (INITIAL): Clear braces_level instead of incrementing it.
11398 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

11401 * configure.ac: Define "lint" if --enable-gcc-warnings.
11403 2002-11-05 Akim Demaille <akim@epita.fr>
11405 * src/scan-gram.l: When it starts with `%', complain about the
11406 whole directive, not just that `invalid character: %'.
11408 2002-11-04 Akim Demaille <akim@epita.fr>
11410 * Makefile.maint: Update from Autoconf.
11411 (update, cvs-update, po-update, do-po-update): New.

11429 Use quote, not quote_n since LOCATION_PRINT no longer uses the
11432 2002-11-03 Paul Eggert <eggert@twinsun.com>
11434 * src/reader.c (get_merge_function, grammar_current_rule_check):
11435 Use consistent diagnostics for reporting type name clashes.
11436 Quote the types with <>, for consistency with Yacc.
11437 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
11439 2002-11-03 Akim Demaille <akim@epita.fr>
11441 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
11443 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
11444 (b4_parse_param): Remove.

11450 Use b4_identification.
11451 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
11452 b4_user_formals and b4_user_args.
11453 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
11454 (yyreportAmbiguity): When using a pure parser, also need
11455 the location, and the parse-params.
11457 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
11458 When using a pure parser, also need the parse-params.
11460 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
11461 (%pure-parser + %parse-param) LALR and GLR parsers.
11462 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
11463 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
11464 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
11465 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
11466 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
11467 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
11468 * doc/bison.texinfo: Untabify the whole file.
11469 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.

11471 (Error Reporting): Adjust to these new directives.
11472 Document %error-verbose, deprecate YYERROR_VERBOSE.
11474 2002-11-03 Akim Demaille <akim@epita.fr>
11476 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
11477 AT_CHECK_CALC_GLR invocations to use % directives, instead of
11478 command line options.
11479 * tests/cxx-type.at: Formatting changes.
11481 2002-11-03 Paul Eggert <eggert@twinsun.com>
11483 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
11484 to count columns correctly, and to check for invalid inputs.
11486 Use mbsnwidth to count columns correctly. Account for tabs, too.
11487 Include mbswidth.h.
11488 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
11489 (extend_location): New function.
11490 (YY_LINES): Remove.
11492 Handle CRLF in C code rather than in Lex code.

11499 Handle backslash-newline correctly in C code.
11500 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
11501 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
11503 (tag, splice): New EREs. Do not allow NUL or newline in tags.
11504 Use {splice} wherever C allows backslash-newline.
11505 YY_STEP after space, newline, vertical-tab.
11506 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
11508 (letter, id): Don't assume ASCII; e.g., spell out a-z.
11510 ({int}, handle_action_dollar, handle_action_at): Check for integer
11513 (YY_STEP): Omit trailing semicolon, so that it's more like C.
11515 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
11516 as well as \000. Check for UCHAR_MAX, not 255.
11517 Allow \x with an arbitrary positive number of digits, as in C.
11518 Check for overflow here.
11519 Allow \? and UCNs, for compatibility with C.
11521 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
11522 with quote slot used by complain_at.
11524 * tests/input.at: Add tests for backslash-newline, m4 quotes
11525 in symbols, long literals, and funny escapes in strings.
11527 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
11528 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

11533 * doc/bison.texinfo (Grammar Outline): Document // comments.
11534 (Symbols): Document that trigraphs have no special meaning in Bison,
11535 nor is backslash-newline allowed.
11536 (Actions): Document that trigraphs have no special meaning.

11541 2002-11-02 Paul Eggert <eggert@twinsun.com>
11543 * src/reader.c: Don't include quote.h; not needed.
11544 (get_merge_function): Reword warning to be consistent with
11545 type clash diagnostic in grammar_current_rule_check.
11547 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
11548 bug in trigraph handling.
11550 * src/output.c (prepare_symbols): When printing token names,
11551 escape "[" as "@<:@" and likewise for "]".
11553 * src/system.h (errno): Remove declaration, as we are now
11554 assuming C89 or better, and C89 guarantees errno.
11556 2002-10-30 Paul Eggert <eggert@twinsun.com>
11558 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
11559 Check for close failures.
11560 * src/files.h (xfclose): Return void, not int, since it always
11562 * src/files.c (xfclose): Likewise. Report I/O error if ferror
11564 * src/output.c (output_skeleton): Use xfclose rather than fclose
11565 and ferror. xfclose now checks ferror.
11567 * data/glr.c (YYLEFTMOST_STATE): Remove.
11568 (yyreportTree): Use a stack-based leftmost state. This avoids
11569 our continuing battles with bogus warnings about initializers.
11571 2002-10-30 Akim Demaille <akim@epita.fr>
11573 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
11576 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11578 * tests/glr-regr1.at: New test for reported regressions.
11579 * tests/testsuite.at: Add glr-regr1.at test.
11580 * tests/Makefile.am: Add glr-regr1.at test.

11586 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
11587 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
11588 we use malloc. Don't assume 'A' through 'Z' are contiguous.
11589 Don't assume strdup exists; POSIX says its an XSI extension.
11590 Check for buffer overflow on input.
11592 2002-10-24 Akim Demaille <akim@epita.fr>
11594 * src/output.c (output_skeleton): Don't disable M4sugar comments
11595 too soon: it results in comments being expanded.
11596 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
11599 2002-10-24 Akim Demaille <akim@epita.fr>
11601 * data/yacc.c (m4_int_type): New.
11602 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
11603 char' as only yacc.c wants K&R portability.
11604 * data/glr.c (yysigned_char): Remove.
11605 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
11606 Reported by Quoc Peyrot.
11608 2002-10-23 Paul Eggert <eggert@twinsun.com>
11610 * src/main.c (main): With --trace=time, report times even if a
11611 non-fatal error occurs. Formerly, the times were reported in some
11612 such cases but not in others.
11613 * src/reader.c (reader): Just return if a complaint has been issued,
11614 instead of exiting, so that 'main' can report times.
11616 2002-10-22 Akim Demaille <akim@epita.fr>
11618 * src/system.h: Include sys/types.
11619 Reported by Bert Deknuydt.
11621 2002-10-23 Paul Eggert <eggert@twinsun.com>
11623 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
11624 Suggested by Art Haas.
11626 2002-10-22 Paul Eggert <eggert@twinsun.com>
11628 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
11629 decl; not needed any more.
11630 * src/main.c (main): Use return to exit, undoing yesterday's change.
11631 The last OS that we could find where this wouldn't work is
11632 SunOS 3.5, and that's too old to worry about now.
11634 * data/glr.c (struct yyltype): Define members even when not
11635 doing locations. This is more consistent with yacc.c, and it
11636 works around the following bug reports:
11637 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
11638 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
11640 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
11641 @acronym consistently. Standardize on "Yacc" instead of "YACC",
11642 "Algol" instead of "ALGOL". Give a bit more history about BNF.
11644 2002-10-22 Akim Demaille <akim@epita.fr>
11646 * data/README: New.
11648 2002-10-21 Paul Eggert <eggert@twinsun.com>
11650 Be consistent about 'bool'; the old code used an enum in one
11651 module and an int in another, and this violates the C standard.
11652 * m4/stdbool.m4: New file, from coreutils 4.5.3.
11653 * configure.ac (AC_HEADER_STDBOOL): Add.
11654 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
11655 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
11656 * src/symtab.c (hash_compare_symbol_t): Likewise.
11657 * src/system.h (bool, false, true): Use a definition consistent
11658 with ../lib/hash.c. All uses changed.
11660 * src/complain.c (warning_issued): Renamed from warn_message_count,
11661 so that we needn't worry about integer overflow (!).
11662 Now of type bool. All uses changed.
11663 (complaint_issued): Renamed from complain_message_count; likewise.
11665 * src/main.c (main): Use exit to exit with failure.
11667 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
11668 rather than 1 and 0.
11669 * src/main.c (main): Likewise.
11670 * src/getargs.c (getargs): Likewise.
11671 * src/reader.c (reader): Likewise.
11673 * src/getarg.c (getargs): Remove duplicate code for
11674 "Try `bison --help'".
11676 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
11677 What was that "2" for?
11679 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
11680 * src/getargs.c (usage): Likewise.
11682 * src/getargs.c (getargs): When there are too few operands, report
11683 the last one. When there are too many, report the first extra
11684 one. This is how diffutils does it.
11686 2002-10-20 Paul Eggert <eggert@twinsun.com>
11688 Remove K&R vestiges.
11689 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
11690 * src/complain.c (VA_START): Remove. Assume prototypes.
11691 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
11692 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
11693 fatal): Assume prototypes.
11694 * src/complain.h: Assume prototypes.
11695 * src/system.h (PARAMS): Remove.
11696 Include <limits.h> unconditionally, since it's guaranteeed even
11697 for a freestanding C89 compiler.
11698 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
11699 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
11701 2002-10-20 Akim Demaille <akim@epita.fr>
11703 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.

11705 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
11706 (yyresolveStates, yyresolveAction, yyresolveStack)
11707 (yyprocessOneStack): Use them.
11708 (yy_reduce_print): New.
11709 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
11711 2002-10-20 Akim Demaille <akim@epita.fr>
11713 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
11714 arguments and output `void'.

11716 (b4_c_function_def): this.
11717 (b4_c_function_decl, b4_c_ansi_function_def)
11718 (b4_c_ansi_function_decl): New.
11719 Change the interpretation of the arguments: before `int, foo', now
11721 * data/yacc.c (yyparse): Prototype and define thanks to these.
11722 Adjust b4_c_function_def uses.
11723 * data/glr.c (yyparse): Likewise, but ANSI only.
11725 2002-10-20 Akim Demaille <akim@epita.fr>
11727 * src/output.c (prepare): Move the definition of `tokens_number',
11728 `nterms_number', `undef_token_number', `user_token_number_max'
11730 (prepare_tokens): Here.
11731 (prepare_tokens): Rename as...
11732 (prepare_symbols): this.
11733 (prepare): Move the definition of `rules_number' to...
11734 (prepare_rules): here.
11735 (prepare): Move the definition of `last', `final_state_number',
11736 `states_number' to...
11737 (prepare_states): here.
11738 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
11740 2002-10-20 Akim Demaille <akim@epita.fr>
11742 * src/tables.h, src/tables.c, src/output.c: Comment changes.
11744 2002-10-20 Akim Demaille <akim@epita.fr>
11746 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
11749 2002-10-20 Akim Demaille <akim@epita.fr>
11751 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
11752 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
11754 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
11756 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
11757 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
11760 2002-10-19 Paul Eggert <eggert@twinsun.com>
11762 Do not create a temporary file, as that involves security and
11763 cleanup headaches. Instead, use a pair of pipes.
11764 Derived from a suggestion by Florian Krohm.
11765 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
11766 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
11767 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
11768 (BISON_PREREQ_SUBPIPE): Add.
11769 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
11770 Add subpipe.h, subpipe.c.

11775 (scan_skel): New decl.
11776 (output_skeleton): Use pipe rather than temporary file for m4 input.
11777 Check that m4sugar.m4 is readable, to avoid deadlock.
11778 Check for pipe I/O error.
11779 * src/scan-skel.l (readpipe): Remove decl.
11780 (scan_skel): New function, to be used in place of m4_invoke.
11781 Read from stream rather than file.
11783 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
11784 float, as this generates a warning on Solaris 8 + GCC 3.2 with
11785 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
11786 this generates a more-accurate value anyway.
11788 * lib/timevar.c (timervar_accumulate): Rename locals to
11789 avoid confusion with similarly-named more-global.
11790 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
11792 * src/output.c (prepare): Use xstrdup to convert char const *
11793 to char *, to avoid GCC warning.
11795 2002-10-19 Akim Demaille <akim@epita.fr>
11797 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
11798 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
11799 Use them to have `calc.y' ready for %pure-parser.
11800 * data/yacc.c (YYLEX): Pass a yylex return type to
11801 b4_c_function_call.
11803 2002-10-19 Akim Demaille <akim@epita.fr>
11805 Prototype support of %lex-param and %parse-param.
11807 * src/parse-gram.y: Add the definition of the %lex-param and
11808 %parse-param tokens, plus their rules.

11818 MUSCLE_INSERT_STRING.
11819 Initialize the obstack earlier.
11820 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
11821 (muscle_pair_list_grow): New.
11822 * data/c.m4 (b4_c_function_call, b4_c_args): New.
11823 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
11824 * tests/calc.at: Use %locations, not --locations.
11825 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
11827 2002-10-19 Akim Demaille <akim@epita.fr>
11829 * src/getargs.c (usage): Take status as argument and exit
11831 Report the traditional `Try ... --help' message when status != 0.
11832 (usage, version): Don't take a FILE * as arg, it is pointless.
11833 (getargs): When there is an incorrect number of arguments, make it
11834 an error, and report it GNUlically thanks to `usage ()'.
11836 2002-10-18 Paul Eggert <eggert@twinsun.com>
11838 * data/glr.c (yyreportParseError): Don't assume that sprintf
11839 yields the length of the printed string, as this is not true
11840 on SunOS 4.1.4. Reported by Peter Klein.
11842 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
11843 * tests/conflicts.at (%nonassoc and eof): Likewise.
11844 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
11846 2002-10-17 Akim Demaille <akim@epita.fr>
11848 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
11849 * src/getargs.c (trace_types, trace_args): Adjust.
11850 * src/reader.c (grammar_current_rule_prec_set)
11851 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
11852 Standardize error messages.
11853 And s/@prec/%prec/!
11854 (reader): Use trace_flag to enable scanner/parser debugging,
11855 instead of an adhoc scheme.
11856 * src/scan-gram.l: Remove trailing debugging code.
11858 2002-10-16 Paul Eggert <eggert@twinsun.com>
11860 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
11863 * NEWS: Officially drop support for building Bison with K&R C,
11864 since it didn't work anyway and it's not worth worrying about.
11865 * Makefile.maint (wget_files): Remove ansi2knr.c.
11866 (ansi2knr.c-url_prefix): Remove.
11867 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
11868 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11869 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11871 2002-10-15 Paul Eggert <eggert@twinsun.com>
11873 Stop using the "enum_" trick for K&R-style function definitions;
11874 it confused me, and I was the author! Instead, assume that people
11875 who want to use K&R C compilers (when using these modules in GCC,
11876 perhaps?) will run ansi2knr.
11878 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
11879 All uses of "enum_" changed to "enum ".
11880 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

11891 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
11892 Use function prototypes; this removes the need for declaring
11893 static functions simply to provide their prototypes.

11951 2002-10-14 Akim Demaille <akim@epita.fr>
11953 * tests/Makefile.am (maintainer-check-posix): New.
11955 2002-10-14 Akim Demaille <akim@epita.fr>
11957 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
11960 2002-10-14 Akim Demaille <akim@epita.fr>
11962 * src/tables.c (table_ninf_remap): base -> tab.
11963 Reported by Matt Rosing.
11965 2002-10-14 Paul Eggert <eggert@twinsun.com>
11967 * tests/action.at, tests/calc.at, tests/conflicts.at,
11968 tests/cxx-type.at, tests/headers.at, tests/input.at,
11969 tests/regression.at, tests/synclines.at, tests/torture.at:
11970 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
11971 so that the tests still work even if POSIXLY_CORRECT is set.
11972 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
11974 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
11975 for portability to K&R hosts. Fix typo: signed char is guaranteed
11976 only to 127, not to 128.
11977 * data/glr.c (yysigned_char): New type.
11978 * data/yacc.c (yysigned_char): Likewise.
11979 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
11981 2002-10-13 Paul Eggert <eggert@twinsun.com>
11983 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
11984 true due to limited range of data type" warning from GCC.
11986 * data/c.m4 (b4_token_defines): Protect against double-inclusion
11987 by wrapping enum yytokentype's definition inside #ifndef
11988 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
11990 2002-10-13 Akim Demaille <akim@epita.fr>
11992 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
11993 Un yy- yyrhs to avoid the name clash with the global YYRHS.
11995 2002-10-13 Akim Demaille <akim@epita.fr>
11997 * Makefile.maint: Update from Autoconf 2.54.
11998 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
12000 2002-10-13 Akim Demaille <akim@epita.fr>
12002 * src/print.c (print_state): Separate the list of solved conflicts
12003 from the other items.
12004 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
12006 2002-10-13 Akim Demaille <akim@epita.fr>
12008 Let nondeterministic skeletons be usable with deterministic
12011 With the patch, GAWK compiled by GCC without -O2 passes its test
12012 suite using a GLR parser driven by LALR tables. It fails with -O2
12013 because `struct stat' gives two different answers on my machine:
12014 88 (definition of an auto var) and later 96 (memset on this var).
12015 Hence the stack is badly corrumpted. The headers inclusion is to
12016 blame: if I move the awk.h inclusion before GLR's system header
12017 inclusion, the two struct stat have the same size.
12019 * src/tables.c (pack_table): Always create conflict_table.
12020 (token_actions): Always create conflict_list.
12021 * data/glr.c (YYFLAG): Remove, unused.
12023 2002-10-13 Akim Demaille <akim@epita.fr>
12025 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
12027 (VALGRIND, GXX): New.
12028 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
12029 * tests/bison.in: Run $PREBISON a pre-command.
12030 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
12031 (maintainer-check-g++): New.
12032 * Makefile.am (maintainer-check): New.
12034 2002-10-13 Akim Demaille <akim@epita.fr>
12036 * data/glr.c: Formatting changes.
12037 Tweak some trace messages to match yacc.c's.
12039 2002-10-13 Akim Demaille <akim@epita.fr>
12041 GLR parsers sometimes raise parse errors instead of performing the
12043 Reported by Charles-Henry de Boysson.
12045 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
12046 check the length of the traces when %glr.
12047 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
12049 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
12051 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
12052 (yyltype): Remove the yy prefix from the member names.
12053 (yytable): Complete its comment.
12054 (yygetLRActions): Map error action number from YYTABLE from
12056 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
12057 (which was a bug: it should have been YYTABEL_NINF, and yet it was
12058 not satisfying as we could compare an YYACTION computed from
12059 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
12060 only value for error actions.
12061 (yyreportParseError): In verbose parse error messages, don't issue
12062 `error' in the list of expected tokens.
12063 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
12064 next action to perform to match glr.c's decoding.
12065 (yytable): Complete its comment.
12067 2002-10-13 Paul Eggert <eggert@twinsun.com>
12069 Fix problem reported by Henrik Grubbstroem in
12070 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
12071 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12072 because the Bison parser reads the second action before reducing
12074 * src/scan-gram.l (rule_length): New static var.
12075 Use it to keep track of the rule length in the scanner, since
12076 we can't expect the parser to be in lock-step sync with the scanner.
12077 (handle_action_dollar, handle_action_at): Use this var.
12078 * tests/actions.at (Exotic Dollars): Test for the problem.
12080 2002-10-12 Paul Eggert <eggert@twinsun.com>
12082 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
12083 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
12084 Include <sys/time.h> when checking for clock_t and struct tms.
12085 Use same include order as source.
12086 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
12087 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
12089 * lib/timevar.c: Update copyright date and clarify comments.
12090 (get_time) [IN_GCC]: Keep the GCC version for reference.
12092 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
12093 GCC version as of today, then merge Bison's changes.
12094 Change "GCC" to "Bison" in copyright notice. timevar.def's
12095 author is Akim, so change that too.
12097 * src/reader.c (grammar_current_rule_check):
12098 Don't worry about the default action if $$ is untyped.
12099 Prevents bogus warnings reported by Jim Gifford in
12100 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
12102 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
12103 * data/glr.c, data/lalr1.cc, data/yacc.c:
12104 Output token definitions before the first part of user declarations.
12105 Fixes compatibility problem reported by Jim Gifford for kbd in
12106 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
12108 2002-10-11 Paul Eggert <eggert@twinsun.com>
12110 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
12111 (yyparse): here. This undoes some of the 2002-07-25 change.
12112 Compatibility problem reported by Ralf S. Engelschall with
12113 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

12132 * lib/lbitset.c: Likewise.
12134 * lib/abitset.c (abitset_bytes): Return a size that is aligned
12135 properly for vectors of objects. Do not assume that adding a
12136 header size to a multiple of a word size yields a value that is
12137 properly aligned for the whole union.
12138 * lib/bitsetv.c (bitsetv_alloc): Likewise.

12174 All instances of parameters of type enum bitset_opts are now of

12178 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12180 Do not use "struct bitset_struct" to mean different things in
12181 different modules. Not only is this confusing, it violates
12182 the C Standard, which requires that structure types in different
12183 modules must be compatible if one is to be passed to the other.
12184 * lib/bbitset.h (bitset): Now points to a union, not to a struct.

12586 to void, to avoid a GCC warning when --disable-nls is in effect.
12588 * src/scan-gram.l: Use strings rather than escapes when possible,
12589 to minimize the number of warnings from xgettext.
12590 (handle_action_dollar, handle_action_at): Don't use isdigit,
12591 as it mishandles negative chars and it may not work as expected
12592 outside the C locale.
12594 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
12595 this is a GCC extension and is not portable to other compilers.

12640 `lookaheads_rule' member.

12646 * src/state.h, src/state.c (state_reductions_find): New.

12831 token_translations instead of `0'.
12832 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
12834 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
12835 for the time being: %locations ought to provide it to yyerror.

15086 2002-02-25 Akim Demaille <akim@epita.fr>
15088 * m4/m4.m4: New, from CVS Autoconf.
15089 * configure.in: Invoke it.
15090 * src/output.c (output_skeleton): Use its result instead of the
15093 2002-02-25 Akim Demaille <akim@epita.fr>
15095 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
15097 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
15098 * src/output.c (output_skeleton): Use mkstemp to create a real
15100 Move the filling of `skeleton' and its muscle to...
15102 (output): Move the definition of the prologue muscle to...
15104 * src/system.h (DEFAULT_TMPDIR): New.
15106 2002-02-14 Paul Eggert <eggert@twinsun.com>
15108 Remove the support for C++ namespace cleanliness; it was
15109 causing more problems than it was curing, since it didn't work
15110 properly on some nonstandard C++ compilers. This can wait
15111 for a proper C++ parser.
15113 * NEWS: Document this.
15114 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
15115 of C++, as it's treated like C now.
15116 * src/bison.simple (YYSTD): Remove.
15117 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
15118 Treat C++ just like Standard C instead of trying to support
15119 namespace cleanliness.
15121 2002-02-14 Akim Demaille <akim@epita.fr>
15123 * tests/regression.at (else): Adjust to Andreas' change.
15125 2002-02-14 Akim Demaille <akim@epita.fr>
15127 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
15129 2002-02-13 Andreas Schwab <schwab@suse.de>
15131 * src/output.c (output_rule_data): Don't output NULL, it might
15132 not be defined yet.
15134 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
15136 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
15137 (Copyright notice): Update.
15139 2002-02-11 Akim Demaille <akim@epita.fr>
15141 * tests/regression.at (%nonassoc and eof): Don't include
15142 nonportable headers.
15144 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
15146 * data/bison.c++: Correct error recovery. Make the user able to
15147 initialize the starting location.
15149 2002-02-07 Akim Demaille <akim@epita.fr>
15151 * tests/input.at: New.
15153 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15155 * data/bison.c++: Replace some direct m4 expansions by constants. Be
15156 more consistent when naming methods and variables. Put preprocessor
15157 directives around tables only needed for debugging.
15159 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15161 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
15163 (yy::b4_name::parse): Use print_.
15165 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15167 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
15169 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15171 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
15173 (yy::b4_name::parse): Build verbose error messages, and use error_.
15175 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
15177 * data/bison.c++: Fix m4 quoting in comments.
15179 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
15181 * data/bison.c++: Adjust the parser code. Fix some muscles that were
15182 not expanded by m4.
15184 2002-02-05 Akim Demaille <akim@epita.fr>
15186 * data/bison.c++: Adjust to the M4 back end.
15187 More is certainly needed.
15189 2002-02-05 Akim Demaille <akim@epita.fr>
15191 Give a try to M4 as a back end.
15193 * lib/readpipe.c: New, from wdiff.
15194 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
15196 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
15197 specific values. Now it is m4 that performs the lookup.
15198 * src/parse-skel.y: Remove.
15199 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
15200 * src/output.c (actions_output, guards_output)
15201 (token_definitions_output): No longer keeps track of the output
15202 line number, hence remove the second argument.
15203 (guards_output): Check against the guard member of a rule, not the
15206 (output_skeleton): Don't look for the skeleton location, let m4 do
15208 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
15210 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
15211 (prepare): Given that for the time being changesyntax is not
15212 usable in M4, rename the muscles using `-' to `_'.
15213 Define `defines_flag', `output_parser_name' and `output_header_name'.
15214 * src/output.h (actions_output, guards_output)
15215 (token_definitions_output): Adjust prototypes.
15216 * src/scan-skel.l: Instead of scanning the skeletons, it now
15217 processes the output of m4: `__oline__' and `#output'.
15218 * data/bison.simple: Adjust to be used by M4(sugar).
15219 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
15221 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
15222 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
15223 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
15224 shamelessly stolen from CVS Autoconf.
15226 2002-02-05 Akim Demaille <akim@epita.fr>
15228 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
15229 * configure.in: Check for the declarations of free and malloc.
15230 * src/muscle_tab.c: Adjust.
15232 2002-02-05 Akim Demaille <akim@epita.fr>
15234 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
15235 which have no values.
15237 2002-02-05 Akim Demaille <akim@epita.fr>
15239 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
15242 2002-01-29 Paul Eggert <eggert@twinsun.com>
15244 * src/bison.simple (YYSIZE_T): Do not define merely because
15245 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
15246 On some platforms, <alloca.h> does not declare YYSTD (size_t).
15248 2002-01-27 Akim Demaille <akim@epita.fr>
15250 Fix `%nonassoc and eof'.
15252 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
15253 which were not properly copied! Replace
15254 memcpy (res->errs, src->errs, src->nerrs);
15256 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
15258 * tests/regression.at (%nonassoc and eof): Adjust to newest
15259 Autotest: `.' is not in the PATH.
15261 2002-01-27 Akim Demaille <akim@epita.fr>
15263 * tests/sets.at (AT_EXTRACT_SETS): New.
15264 (Nullable): Use it.
15267 2002-01-26 Akim Demaille <akim@epita.fr>
15269 * tests/actions.at, tests/calc.at, tests/headers.at,
15270 * tests/torture.at: Adjust to the newest Autotest which no longer
15271 forces `.' in the PATH.
15273 2002-01-25 Akim Demaille <akim@epita.fr>
15275 * tests/regression.at (%nonassoc and eof): New.
15276 Suggested by Robert Anisko.
15278 2002-01-24 Akim Demaille <akim@epita.fr>
15280 Bison dumps core when trying to complain about broken input files.
15281 Reported by Cris van Pelt.
15283 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
15284 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
15286 (Invalid inputs): Strengthen: exercise parse_percent_token.
15288 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
15290 * src/Makefile.am: Add bison.c++.
15291 * src/bison.c++: New skeleton.
15293 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
15297 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
15299 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
15301 2002-01-20 Marc Autret <marc@gnu.org>
15303 * src/files.c (compute_output_file_names): Fix
15305 2002-01-20 Marc Autret <marc@gnu.org>
15307 * tests/output.at: New test.
15308 * src/files.c (compute_base_names): Don't map extensions when
15309 the YACC flag is set, use defaults.
15310 Reported by Evgeny Stambulchik.
15312 2002-01-20 Marc Autret <marc@gnu.org>
15314 * src/system.h: Need to define __attribute__ away for non-GCC
15315 compilers as well (i.e., the vendor C compiler).
15316 Suggested by Albert Chin-A-Young.
15318 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
15320 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
15321 canonical definition.
15322 * src/system.h: Use the canonical definition for PARAMS (avoids
15323 a conflict with the macro from lib/hash.h).
15325 2002-01-11 Akim Demaille <akim@epita.fr>
15327 * configure.in: Use AC_FUNC_STRNLEN.
15328 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
15330 2002-01-09 Akim Demaille <akim@epita.fr>
15332 * src/files.c, src/files.h (output_infix): New.
15333 (tab_extension): Remove.
15334 (compute_base_names): Compute the former, drop the latter.
15335 * src/output.c (prepare): Insert the muscles `output-infix', and
15337 * src/parse-skel.y (string, string.1): New.
15338 (section.header): Use it.
15339 (section.yacc): Remove.
15340 (prefix): Remove too.
15341 * src/scan-skel.l: Adjust.
15342 * src/bison.simple, src/bison.hairy: Adjust.
15344 2002-01-09 Akim Demaille <akim@epita.fr>
15346 * configure.in (WERROR_CFLAGS): Compute it.
15347 * src/Makefile.am (CFLAGS): Pass it.
15348 * tests/atlocal.in (CFLAGS): Idem.
15349 * src/files.c: Fix a few warnings.
15350 (get_extension_index): Remove, unused.
15352 2002-01-08 Akim Demaille <akim@epita.fr>
15354 * src/getargs.c (AS_FILE_NAME): New.
15355 (getargs): Use it to convert DOSish file names.
15356 * src/files.c (base_name): Rename as full_base_name to avoid
15357 clashes with `base_name ()'.
15358 (filename_split): New.
15359 (compute_base_names): N-th rewrite, using filename_split.
15361 2002-01-08 Akim Demaille <akim@epita.fr>
15363 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
15364 New, stolen from the Fileutils 4.1.
15365 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
15366 * configure.in: Check for the presence of memrchr, and of its
15369 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
15371 * lib/hash.h (__P): Added definition for this macro.
15372 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
15373 BUILT_SOURCES, to ensure they are generated first.
15374 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
15375 %error-verbose to allow bootstrapping with bison 1.30x.
15377 2002-01-06 Akim Demaille <akim@epita.fr>
15379 * src/reader.c (parse_braces): Don't fetch the next char, the
15380 convention is to fetch on entry.
15381 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
15382 'switch' without a following semicolon.
15383 * tests/regression.at (braces parsing): New.
15385 2002-01-06 Akim Demaille <akim@epita.fr>
15387 Bison is dead wrong in its RR conflict reports.
15389 * tests/torture.at (GNU Cim Grammar): New.
15390 * src/conflicts.c (count_rr_conflicts): Fix.
15392 2002-01-06 Akim Demaille <akim@epita.fr>
15394 Creating package.m4 from configure.ac causes too many problems.
15396 * tests/Makefile.am (package.m4): Create it by hand,
15397 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
15399 2002-01-06 Akim Demaille <akim@epita.fr>
15401 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
15404 2002-01-04 Paul Eggert <eggert@twinsun.com>
15406 * doc/bison.texinfo (Debugging):
15407 Remove YYSTDERR; it's no longer defined or used.
15408 Also, s/cstdio.h/cstdio/.
15410 2002-01-03 Akim Demaille <akim@epita.fr>
15412 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
15414 2002-01-03 Akim Demaille <akim@epita.fr>
15416 * src/parse-skel.y (process_skeleton): Don't bind the parser's
15417 tracing code to --trace, wait for a better --trace option, with
15420 2002-01-03 Akim Demaille <akim@epita.fr>
15422 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
15423 The ISO C++ standard is extremely clear about it: stderr is
15424 considered a macro, not a regular symbol (see table 94 `Header
15425 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
15426 Therefore std:: does not apply to it. It still does with fprintf.
15427 Also, s/cstdio.h/cstdio/.
15429 2002-01-03 Akim Demaille <akim@epita.fr>
15431 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
15432 for non system headers.
15434 2002-01-02 Akim Demaille <akim@epita.fr>
15436 Equip the skeleton chain with location tracking, runtime trace,
15437 pure parser and scanner.
15439 * src/parse-skel.y: Request a pure parser, locations, and prefix
15441 (%union): Having several members with the same type does not help
15442 type mismatches, simplify.
15443 (YYPRINT, yyprint): New.
15444 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
15445 (skel_error): this.
15447 * src/scan-skel.l: Adjust to these changes.
15448 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
15449 (LOCATION_PRINT, skel_control_t): New.
15451 2001-12-30 Akim Demaille <akim@epita.fr>
15453 * src/parse-skel.y: Get rid of the shift/reduce conflict:
15454 replace `gb' with BLANKS.
15455 * src/scan-skel.l: Adjust.
15457 2001-12-30 Akim Demaille <akim@epita.fr>
15459 * src/system.h: We don't need nor want bcopy.
15460 Throw away MS-DOS crap: we don't need getpid.
15461 * configure.in: We don't need strndup. It was even causing
15462 problems: because Flex includes the headers *before* us,
15463 _GNU_SOURCE is not defined by config.h, and therefore strndup was
15465 * lib/xstrndup.c: New.
15466 * src/scan-skel.l: Use it.
15467 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
15468 * src/parse-skel.y: Use %directives instead of #defines.
15470 2001-12-30 Akim Demaille <akim@epita.fr>
15472 * src/skeleton.h: New.
15473 * src/output.c (output_parser, output_master_parser): Remove, dead
15475 * src/output.h (get_lines_number, actions_output, guards_output)
15476 (token_definitions_output): Prototype them.
15477 * src/parse-skel.y: Add the license notice.
15478 Include output.h and skeleton.h.
15479 (process_skeleton): Returns void, and takes a single parameter.
15480 * src/scan-skel.l: Add the license notice.
15481 Include skeleton.h.
15482 Don't use %option yylineno: it seems that then Flex imagines
15483 REJECT has been used, and therefore it won't reallocate its
15484 buffers (which makes no other sense to me than a bug). It results
15485 in warnings for `unused: yy_flex_realloc'.
15487 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
15489 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15490 (MUSCLE_INSERT_PREFIX): ...to there.
15491 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15492 (MUSCLE_INSERT_PREFIX): Move from here...
15494 * src/bison.hairy: Add a section directive. Put braces around muscle
15495 names. This parser skeleton is still broken, but Bison should not
15496 choke on a bad muscle 'syntax'.
15497 * src/bison.simple: Add a section directive. Put braces around muscle
15500 * src/files.h (strsuffix, stringappend): Add declarations.
15501 (tab_extension): Add declaration.
15502 (short_base_name): Add declaration.
15504 * src/files.c (strsuffix, stringappend): No longer static. These
15505 functions are used in the skeleton parser.
15506 (tab_extension): New.
15507 (compute_base_names): Use the computations done in this function
15508 to guess if the generated parsers should have '.tab' in their
15510 (short_base_name): No longer static.
15512 * src/output.c (output_skeleton): New.
15513 (output): Disable call to output_master_parser, and give a try to
15514 a new skeleton handling system.
15515 (guards_output, actions_output): No longer static.
15516 (token_definitions_output, get_lines_number): No longer static.
15518 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
15520 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
15523 * src/parse-skel.y: New file.
15524 * src/scan-skel.l: New file.
15526 2001-12-29 Akim Demaille <akim@epita.fr>
15528 %name-prefix is broken.
15530 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
15531 Adjust all dependencies.
15532 * tests/headers.at (export YYLTYPE): Strengthen this test: use
15535 Renaming yylval but not yylloc is not consistent. Now we do.
15537 * src/bison.simple: Prefix yylloc if used.
15538 * doc/bison.texinfo (Decl Summary): Document that.
15540 2001-12-29 Akim Demaille <akim@epita.fr>
15542 * doc/bison.texinfo: Promote `%long-directive' over
15544 Remove all references to fixed-output-files, yacc is enough.
15546 2001-12-29 Akim Demaille <akim@epita.fr>
15548 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
15549 user prologue. These are defaults.
15550 * tests/actions.at (Mid-rule actions): Make sure the user can
15551 define YYDEBUG and YYERROR_VERBOSE.
15553 2001-12-29 Akim Demaille <akim@epita.fr>
15555 * src/output.c (header_output): Don't forget to export YYLTYPE and
15557 * tests/headers.at (export YYLTYPE): New, make sure it does.
15558 * tests/regression.at (%union and --defines, Invalid CPP headers):
15560 * tests/headers.at: here.
15562 2001-12-29 Akim Demaille <akim@epita.fr>
15564 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
15566 2001-12-29 Akim Demaille <akim@epita.fr>
15568 * tests/actions.at (Mid-rule actions): Output on a single line
15569 instead of several.
15571 2001-12-29 Akim Demaille <akim@epita.fr>
15573 * doc/bison.texinfo: Formatting changes.
15575 2001-12-29 Akim Demaille <akim@epita.fr>
15577 Don't store the token defs in a muscle, just be ready to output it
15578 on command. Now possible via `symbols'. Fixes a memory leak.
15580 * src/output.c (token_definitions_output): New.
15581 (output_parser, header_output): Use it.
15582 * src/reader.c (symbols_save): Remove.
15584 2001-12-29 Akim Demaille <akim@epita.fr>
15586 * src/bison.simple: Do not provide a default for YYSTYPE and
15587 YYLTYPE before the user's prologue. Otherwise it's hardly... a
15590 2001-12-29 Akim Demaille <akim@epita.fr>
15592 Mid-rule actions are simply... ignored!
15594 * src/reader.c (readgram): Be sure to attach mid-rule actions to
15595 the empty-rule associated to the dummy symbol, not to the host
15597 * tests/actions.at (Mid-rule actions): New.
15599 2001-12-29 Akim Demaille <akim@epita.fr>
15603 * src/reader.c (reader): Free grammar.
15605 2001-12-29 Akim Demaille <akim@epita.fr>
15609 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
15610 since it allocates it for each state, although only one is needed.
15611 (allocate_storage): Do it here.
15613 2001-12-29 Akim Demaille <akim@epita.fr>
15615 * src/options.h, src/options.c (create_long_option_table): Rename
15617 (long_option_table_new): this, with a clearer prototype.
15618 (percent_table): Remove, unused,
15619 * src/getargs.c (getargs): Adjust.
15621 2001-12-29 Akim Demaille <akim@epita.fr>
15623 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
15624 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
15627 2001-12-29 Akim Demaille <akim@epita.fr>
15629 * src/lalr.c (build_relations): Rename `states' as `states1'.
15630 Sorry, I don't understand exactly what it is, no better name...
15632 2001-12-29 Akim Demaille <akim@epita.fr>
15634 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
15635 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

15647 Adjust all users to use symbols[i]->user_token_number.

15651 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
15652 Adjust all users to use symbols[i]->prec or ->assoc.
15654 2001-12-29 Akim Demaille <akim@epita.fr>
15656 * src/reader.c, src/reader.h (tags): Remove.
15657 Adjust all users to use symbols[i]->tag.
15659 2001-12-29 Akim Demaille <akim@epita.fr>
15661 * src/gram.h, src/gram.c (symbols): New, similar to state_table
15663 * src/reader.c (packsymbols): Fill this table.
15665 * src/conflicts.c (resolve_sr_conflict): Adjust.
15666 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
15668 Use symbols[i]->tag instead of tags[i].
15670 2001-12-29 Akim Demaille <akim@epita.fr>
15672 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
15673 In addition, put a comment in there, to replace...
15674 * tests/regression.at (%union and C comments): Remove.
15676 2001-12-29 Akim Demaille <akim@epita.fr>
15678 * tests/regression.at (Web2c Actions): Blindly move the actual
15679 output as expected output. The contents *seem* right to me, but I
15680 can't pretend reading perfectly parser tables... Nonetheless, all
15681 the other tests pass correctly, the table look OK, even though the
15682 presence of `$axiom' is to be noted: AFAICS it is useless (but
15685 2001-12-29 Akim Demaille <akim@epita.fr>
15687 * src/reader.c (readgram): Don't add the rule 0 if there were no
15688 rules read. In other words, add it _after_ having performed
15689 grammar sanity checks.
15690 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
15692 2001-12-29 Akim Demaille <akim@epita.fr>
15694 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
15695 visible, and some states have now a different number.
15697 2001-12-29 Akim Demaille <akim@epita.fr>
15699 * src/reader.c (readgram): Bind the initial rule's lineno to that
15701 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
15702 (Solved SR Conflicts): Adjust rule 0's line number.
15704 2001-12-29 Akim Demaille <akim@epita.fr>
15706 Fix the `GAWK Grammar' failure.
15708 * src/LR0.c (final_state): Initialize to -1 so that we do compute
15709 the reductions of the first state which was mistakenly confused
15710 with the final state because precisely final_state was initialized
15712 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
15713 now noticed by Bison.
15714 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
15715 have a reduction on $default.
15717 2001-12-29 Akim Demaille <akim@epita.fr>
15719 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
15721 * src/closure.c (print_closure): Likewise.
15722 * src/derives.c (print_derives): Likewise.
15723 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
15726 2001-12-29 Akim Demaille <akim@epita.fr>
15728 * src/lalr.c (lookaheads_print): New.
15729 (lalr): Call it when --trace-flag.
15730 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
15733 2001-12-29 Akim Demaille <akim@epita.fr>
15735 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
15736 when walking through ritem, even via rule->rhs.
15737 * src/reduce.c (dump_grammar, useful_production, reduce_output)
15738 (useful_production, useless_nonterminals): Likewise.
15739 (reduce_grammar_tables): Likewise, plus update nritems.
15740 * src/nullable.c (set_nullable): Likewise.
15741 * src/lalr.c (build_relations): Likewise.
15742 * tests/sets.at (Nullable): Adjust.
15743 Fortunately, now, the $axiom is no longer nullable.
15745 2001-12-29 Akim Demaille <akim@epita.fr>
15747 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

15755 2001-12-29 Akim Demaille <akim@epita.fr>
15757 * src/output.c: Comment changes.
15759 2001-12-27 Paul Eggert <eggert@twinsun.com>
15761 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
15762 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
15763 Sparc, as they were causing more porting problems than the
15764 (minor) performance improvement was worth.
15766 Also, catch up with 1.31's YYSTD.
15768 2001-12-27 Akim Demaille <akim@epita.fr>
15770 * src/output.c (output_gram): Rely on nritems, not the
15771 0-sentinel. See below.
15772 Use -1 as separator, not 0.
15773 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
15774 Rely on -1 as separator in yyrhs, instead of 0.
15775 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
15776 twice `Now at end of input', therefore there are two lines less to
15779 2001-12-27 Akim Demaille <akim@epita.fr>
15781 * tests/regression.at (Unresolved SR Conflicts):
15782 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
15785 2001-12-27 Akim Demaille <akim@epita.fr>
15787 * src/LR0.c (new_state): Recognize the final state by the fact it
15788 is reached by eoftoken.
15789 (insert_start_shifting_state, insert_eof_shifting_state)
15790 (insert_accepting_state, augment_automaton): Remove, since now
15791 these states are automatically computed from the initial state.
15792 (generate_states): Adjust.
15793 * src/print.c: When reporting a rule number to the user, substract
15794 1, so that the axiom rule is rule 0, and the first user rule is 1.
15795 * src/reduce.c: Likewise.
15796 * src/print_graph.c (print_core): For the time being, just as for
15797 the report, depend upon --trace-flags to dump the full set of
15799 * src/reader.c (readgram): Once the grammar read, insert the rule
15800 0: `$axiom: START-SYMBOL $'.
15801 * tests/set.at: Adjust: rule 0 is now displayed, and since the
15802 number of the states has changed (the final state is no longer
15803 necessarily the last), catch up.
15805 2001-12-27 Akim Demaille <akim@epita.fr>
15807 Try to make the use of the eoftoken valid. Given that its value
15808 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
15809 is used instead of > 0 where appropriate, (ii), depend upon nritems
15810 instead of the 0-sentinel.
15812 * src/gram.h, src/gram.c (nritems): New.
15813 Expected to be duplication of nitems, but for the time being...
15814 * src/reader.c (packgram): Assert nritems and nitems are equal.
15815 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
15816 * src/closure.c (print_closure, print_fderives): Likewise.

15819 * src/print_graph.c: Likewise.
15821 2001-12-27 Akim Demaille <akim@epita.fr>
15823 * src/main.c (main): If there are complains after grammar
15824 reductions, then output the report anyway if requested, then die.
15825 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
15826 * src/reader.c (eoftoken): New.
15827 (parse_token_decl): If the token being defined has value `0', it
15829 (packsymbols): No longer hack `tags' to insert `$' by hand.
15830 Be sure to preserve the value of the eoftoken.
15831 (reader): Make sure eoftoken is defined.
15832 Initialize nsyms to 0: now eoftoken is created just like the others.
15833 * src/print.c (print_grammar): Don't special case the eof token.
15834 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
15835 lie anyway, albeit pleasant.
15836 * tests/calc.at: Exercise error messages with eoftoken.
15837 Change the grammar so that empty input is invalid.
15838 Adjust expectations.
15839 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
15841 2001-12-27 Akim Demaille <akim@epita.fr>
15843 * configure.in: Check the protos of strchr ans strspn.
15844 Replace strchr if needed.
15845 * src/system.h: Provide the protos of strchr, strspn and memchr if
15847 * lib/strchr.c: New.
15848 * src/reader.c (symbols_save): Use strchr.
15850 2001-12-27 Akim Demaille <akim@epita.fr>
15852 * src/print.c, src/print_graph.c (escape): New.
15853 Use it to quote the TAGS outputs.
15854 * src/print_graph.c (print_state): Now errors are in red, and
15855 reductions in green.
15856 Prefer high to wide: output the state number on a line of its own.
15858 2001-12-27 Akim Demaille <akim@epita.fr>
15860 * src/state.h, src/state.c (reductions_new): New.
15861 * src/LR0.c (set_state_table): Let all the states have a
15862 `reductions', even if reduced to 0.

15881 2001-12-27 Akim Demaille <akim@epita.fr>
15883 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
15884 * src/print.c: here.
15885 (lookaheadset, shiftset): New, used as additional storage by
15887 (print_results): Adjust.
15888 (print_shifts, print_gotos, print_errs): New, extracted from...
15889 (print_actions): here.
15890 * src/print_graph.c (print_actions): Remove dead code.
15892 2001-12-27 Akim Demaille <akim@epita.fr>
15894 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
15897 2001-12-27 Akim Demaille <akim@epita.fr>
15899 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

15914 * src/output.c (output): Adjust.
15915 * src/reader.c (parse_braces): New, factoring...
15916 (copy_action, copy_guard): these two which are renamed as...
15917 (parse_action, parse_guard): these.
15918 As a voluntary consequence, using braces around guards is now
15921 2001-12-27 Akim Demaille <akim@epita.fr>
15923 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
15924 * src/reader.c (symbol_list): `guard' and `guard_line' are new
15926 (symbol_list_new): Adjust.
15927 (copy_action): action_line is the first line, not the last.
15928 (copy_guard): Just as for actions, store the `action' only, not
15929 the switch/case/break flesh.
15930 Don't parse the user action that might follow the guard, let...
15931 (readgram): do it, i.e., now, there can be an action after a
15933 In other words the guard is just explicitly optional.
15934 (packgram): Adjust.
15935 * src/output.c (guards_output): New.
15936 (output_parser): Call it when needed.
15937 (output): Also free the guard and attrs obstacks.
15938 * src/files.c, src/files.h (obstack_save): Remove.
15939 (output_files): Remove.
15940 As a result, if one needs the former `.act' file, using an
15941 appropriate skeleton which requires actions and guards is now
15943 * src/main.c (main): Adjust.
15944 * tests/semantic.at: New.
15945 * tests/regression.at: Use `input.y' as input file name.
15946 Avoid 8+3 problems by requiring input.c when the test needs the

15951 * src/reader.c (symbol_list_new): Be sure to initialize all the
15954 2001-12-27 Akim Demaille <akim@epita.fr>
15956 All the hacks using a final pseudo state are now useless.
15958 * src/LR0.c (set_state_table): state_table holds exactly nstates.
15959 * src/lalr.c (nLA): New.
15960 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
15961 instead of lookaheadsp from the pseudo state (nstate + 1).
15963 2001-12-27 Akim Demaille <akim@epita.fr>
15965 * src/output.c (action_row, token_actions): Use a state_t instead
15966 of a integer, and nlookaheads instead of the following state's

15973 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
15974 (conflicts_print, print_reductions): Use a state_t instead of an
15975 integer when referring to a state.
15976 As much as possible, depend upon nlookaheads, instead of the
15977 `lookaheadsp' member of the following state (since lookaheads of
15978 successive states are successive, the difference between state n + 1
15979 and n served as the number of lookaheads for state n).
15980 * src/lalr.c (add_lookback_edge): Likewise.
15981 * src/print.c (print_core, print_actions, print_state)
15982 (print_results): Likewise.

15992 Add plenty of `static'.
15994 2001-12-27 Akim Demaille <akim@epita.fr>
15996 * src/output.c (prepare): Drop the muscle `ntbase' which
15997 duplicates ntokens.
15998 * src/bison.simple: Formatting/comment changes.
15999 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
16000 is an undocumented synonym.
16002 2001-12-22 Akim Demaille <akim@epita.fr>
16004 * src/output.c (output_table_data): Change the prototype to use
16005 `int' for array ranges: some invocations do pass an int, not a
16007 Reported by Wayne Green.
16009 2001-12-22 Akim Demaille <akim@epita.fr>
16011 Some actions of web2c.y are improperly triggered.

16027 2001-12-18 Akim Demaille <akim@epita.fr>
16029 Some host fail on `assert (!"foo")', which expands to
16030 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
16031 Reported by Nelson Beebee.
16033 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
16034 `#define it_succeeded 0' and `assert (it_succeeded)'.
16036 2001-12-17 Marc Autret <autret_m@epita.fr>
16038 * src/bison.simple: Don't hard code the skeleton line and filename.
16039 * src/output.c (output_parser): Rename 'line' as 'output_line'.
16040 New line counter 'skeleton_line' (skeleton-line muscle).
16042 2001-12-17 Paul Eggert <eggert@twinsun.com>
16044 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
16045 YYDEBUG must be defined to a nonzero value.
16047 * src/bison.simple (yytname): Do not assume that the user defines
16048 YYDEBUG to a properly parenthesized expression.
16050 2001-12-17 Akim Demaille <akim@epita.fr>
16052 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
16053 nlookaheads is a new member.
16055 * src/lalr.h (nlookaheads): Remove this orphan declaration.
16056 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
16059 2001-12-17 Akim Demaille <akim@epita.fr>
16061 * src/files.h, src/files.c (open_files, close_files): Remove.
16062 * src/main.c (main): Don't open/close files, nor invoke lex_free,
16064 * src/reader.c (reader): Do it.
16066 2001-12-17 Akim Demaille <akim@epita.fr>
16068 * src/conflicts.c (print_reductions): Formatting changes.
16070 2001-12-17 Akim Demaille <akim@epita.fr>

16081 * src/reader.h (muscle_obstack): Move to...

16084 2001-12-17 Akim Demaille <akim@epita.fr>
16086 * src/output.c (action_row, save_column, default_goto)

16099 * src/print_graph.c (print_graph): Work unconditionally.
16100 * src/conflicts.c (log_resolution): Output only if verbose_flag.
16102 2001-12-16 Marc Autret <autret_m@epita.fr>
16104 * src/output.c (actions_output): Fix. When we use %no-lines,
16105 there is one less line per action.
16107 2001-12-16 Marc Autret <autret_m@epita.fr>
16109 * src/bison.simple: Remove a useless #line directive.
16110 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
16111 * src/output.c (get_lines_number): New.
16112 (output_parser): Adjust, now takes care about the lines of a
16114 Fix line numbering.
16115 (actions_output): Computes the number of lines taken by actions.
16116 (output_master_parser): Insert new skeleton which is the name of
16117 the output parser file name.
16119 2001-12-15 Marc Autret <autret_m@epita.fr>
16121 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
16123 2001-12-15 Marc Autret <autret_m@epita.fr>
16125 * src/output.c (output_gram): Keep track of the hairy one.
16127 2001-12-15 Akim Demaille <akim@epita.fr>
16129 Make `make distcheck' work.
16131 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
16132 system.h which uses libgettext.h.
16134 2001-12-15 Akim Demaille <akim@epita.fr>
16136 * src/nullable.c (set_nullable): Useless rules must be skipped,
16137 otherwise, since we range over their symbols, we might look at a
16138 nonterminal which no longer ``exists'', i.e., it is not counted in
16139 `nvars', hence we overflow our arrays.
16141 2001-12-15 Akim Demaille <akim@epita.fr>
16143 The header can also be produced directly, without any obstack!
16146 * src/files.c, src/files.h (defines_obstack): Remove.
16147 (compute_header_macro): Global.
16148 (defines_obstack_save): Remove.
16149 * src/reader.c (parse_union_decl): No longer output to
16150 defines_obstack: its content can be found in the `stype' muscle
16152 (output_token_translations): Merge into...
16153 (symbols_output): this.
16155 (symbols_save): this.
16157 * src/output.c (header_output): New.
16160 2001-12-15 Akim Demaille <akim@epita.fr>
16162 * src/reader.c (parse_union_decl): Instead of handling two obstack
16163 simultaneously, use one to define the `stype' muscle, and use the
16164 value of the latter to fill defines_obstack.
16165 (copy_comment): Remove.
16166 (copy_comment2): Work for a single obstack.
16168 (copy_comment): this.
16170 2001-12-15 Akim Demaille <akim@epita.fr>
16172 * src/lex.c, src/lex.h (xgetc): No longer static.
16173 * src/reader.c (parse_union_decl): Revamp.
16175 2001-12-15 Akim Demaille <akim@epita.fr>
16177 Still making progress in separating Bison into (i) input, (ii)
16178 process, (iii) output: now we can directly output the parser file
16179 without using table_obstack at all.
16181 * src/files.c, src/files.h (table_obstack): Bye bye.
16182 (parser_file_name): New.
16183 * src/files.c (compute_output_file_names): Compute it.
16184 * src/output.c (actions_output, output_parser)
16185 (output_master_parser): To a file instead of an obstack.
16187 2001-12-15 Akim Demaille <akim@epita.fr>
16189 Attach actions to rules, instead of pre-outputting them to
16192 * src/gram.h (rule_t): action and action_line are new members.
16193 * src/reader.c (symbol_list): Likewise.
16194 (copy_action): Save the actions within the rule.
16195 (packgram): Save them in rule_table.
16196 * src/output.c (actions_output): New.
16197 (output_parser): Use it on `%%actions'.
16198 (output_rule_data): Don't free rule_table.
16200 (prepare): Don't save the `action' muscle.
16201 * src/bison.simple: s/%%action/%%actions/.
16203 2001-12-15 Akim Demaille <akim@epita.fr>
16205 * src/reader.c (copy_action): When --yacc, don't append a `;'
16206 to the user action: let it fail if lacking.
16207 Suggested by Arnold Robbins and Tom Tromey.
16209 2001-12-14 Akim Demaille <akim@epita.fr>
16211 * src/lex.c (literalchar): Simply return the char you decoded, non
16212 longer mess around with obstacks and int pointers.
16213 Adjust all callers.
16215 2001-12-14 Akim Demaille <akim@epita.fr>
16217 * src/lex.c (literalchar): Don't escape the special characters,
16218 just decode them, and keep them as char (before, eol was output as
16219 the 2 char string `\n' etc.).
16220 * src/output.c (output_rule_data): Use quotearg to output the
16223 2001-12-13 Paul Eggert <eggert@twinsun.com>
16225 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
16226 Do not infringe on the global user namespace when using C++.
16227 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
16228 All uses of `fprintf' and `stderr' changed.
16230 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
16232 2001-12-13 Akim Demaille <akim@epita.fr>
16234 The computation of nullable is broken: it doesn't handle empty
16237 * tests/torture.at (GNU AWK Grammar): New.
16238 * tests/sets.at (Nullable): New.
16239 * src/nullable.c (set_nullable): Instead of blindly looping over
16240 `ritems', loop over the rules, and then over their rhs's.
16242 Work around Autotest bugs.
16244 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
16245 frame, because Autotest understand lines starting with a `+' as
16246 traces from the shell. Then, they are not processed properly.
16247 Admittedly an Autotest bug, but we don't have time to wait for
16248 Autotest to catch up.
16249 * tests/regression.at (Broken Closure): Adjust to the new table
16252 * tests/sets.at: here.
16254 2001-12-13 Akim Demaille <akim@epita.fr>
16256 * src/closure.c (closure): Use nrules instead of playing tricks
16257 with BITS_PER_WORD.
16259 2001-12-13 Akim Demaille <akim@epita.fr>
16261 * src/print.c (print_actions): Output the handling of `$' as the
16262 traces do: shifting the token EOF. Before EOF was treated as a
16264 * tests/regression.at: Adjust some tests.
16265 * src/print_graph.c (print_core): Complete the set of items via
16266 closure. The next-to-final and final states are still unsatisfying,
16267 but that's to be addressed elsewhere.
16268 No longer output the rule numbers, but do output the state number.
16269 A single loop for the shifts + gotos is enough, but picked a
16270 distinct color for each.
16271 (print_graph): Initialize and finalize closure.
16273 2001-12-13 Akim Demaille <akim@epita.fr>
16275 * src/reader.c (readgram): Remove dead code, an strip useless
16277 (get_type): Remove, unused.
16279 2001-12-12 Akim Demaille <akim@epita.fr>
16281 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
16282 on that of lib/error.c.
16284 2001-12-12 Akim Demaille <akim@epita.fr>
16286 Some hosts don't like `/' in includes.
16288 * src/system.h: Include libgettext.h without qualifying the path.
16289 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
16292 2001-12-11 Marc Autret <autret_m@epita.fr>
16294 * src/output.c (output_parser): Remove useless muscle.
16296 2001-12-11 Marc Autret <autret_m@epita.fr>
16298 * src/bison.simple: Remove #line just before %%epilogue. It
16299 is now handled in ...
16300 * src/reader.c (read_additionnal_code): Add the output of a
16301 #line for the epilogue.
16303 2001-12-10 Marc Autret <autret_m@epita.fr>
16305 * src/reader.c (copy_definition): Re-use CPP-outed code which
16306 replace precedent remove.
16307 * src/bison.simple: Remove #line before %%prologue because
16308 %%input-line is wrong at this time.
16310 2001-12-10 Marc Autret <autret_m@epita.fr>
16312 * src/reader.c (symbols_output): Clean up.
16313 * src/output.c (output_gram, output): Clean up.
16315 2001-12-10 Akim Demaille <akim@epita.fr>
16317 * src/lalr.c (initialize_lookaheads): New. Extracted from...
16318 * src/LR0.c (set_state_table): here.
16319 * src/lalr.c (lalr): Call it.
16321 2001-12-10 Akim Demaille <akim@epita.fr>
16323 * src/state.h (shifts): Remove the `number' member: shifts are
16324 attached to state, hence no longer need to be labelled with a
16327 2001-12-10 Akim Demaille <akim@epita.fr>
16329 Now that states have a complete set of members, the linked list of
16330 shifts is useless: just fill directly the state's shifts member.
16332 * src/state.h (shifts): Remove the `next' member.
16333 * src/LR0.c (first_state, last_state): Remove.
16334 Adjust the callers.
16335 (augment_automaton): Don't look for the shifts that must be added
16336 a shift on EOF: it is those of the state we looked for! But now,
16337 since shifts are attached, it is no longer needed to looking
16338 merely by its id: its number.
16340 2001-12-10 Akim Demaille <akim@epita.fr>
16342 * src/LR0.c (augment_automaton): Better variable locality.
16343 Remove an impossible branch: if there is a state corresponding to
16344 the start symbol being shifted, then there is shift for the start
16345 symbol from the initial state.
16347 2001-12-10 Akim Demaille <akim@epita.fr>
16349 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
16350 only when appropriate: when insert_start_shifting_state' is not
16352 * tests/regression.at (Rule Line Numbers): Adjust.
16354 2001-12-10 Akim Demaille <akim@epita.fr>
16356 * src/LR0.c (augment_automaton): Now that all states have shifts,
16357 merge the two cases addition shifts to the initial state.
16359 2001-12-10 Akim Demaille <akim@epita.fr>
16361 * src/lalr.c (set_state_table): Move to...
16363 * src/lalr.c (lalr): Don't call it...
16364 * src/LR0.c (generate_states): do it.
16365 * src/LR0.h (first_state): Remove, only the table is used.
16367 2001-12-10 Akim Demaille <akim@epita.fr>
16369 * src/LR0.h (first_shift, first_reduction): Remove.
16370 * src/lalr.c: Don't use first_shift: find shifts through the
16373 2001-12-10 Akim Demaille <akim@epita.fr>
16375 * src/LR0.c: Attach shifts to states as soon as they are
16377 * src/lalr.c (set_state_table): Instead of assigning shifts to
16378 state, just assert that the mapping was properly done.
16380 2001-12-10 Akim Demaille <akim@epita.fr>
16382 * src/LR0.c (insert_start_shift): Rename as...
16383 (insert_start_shifting_state): this.
16384 (insert_eof_shifting_state, insert_accepting_state): New.
16385 (augment_automaton): Adjust.
16386 Better locality of the variables.
16387 When looking if the start_symbol is shifted from the initial
16388 state, using `while (... symbol != start_symbol ...)' sounds
16389 better than `while (... symbol < start_symbol ...)': If fail
16390 to see how the order between symbols could be relevant!
16392 2001-12-10 Akim Demaille <akim@epita.fr>
16394 * src/getargs.h: Don't declare `spec_name_prefix' and
16395 `spec_file_prefix', declared by src/files.h.
16396 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
16397 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
16398 * src/output.c (prepare): Adjust.
16399 * src/reader.c (symbols_output): Likewise.
16400 * src/vmsgetargs.c: Vaguely adjust, but who cares?
16402 2001-12-10 Akim Demaille <akim@epita.fr>
16404 * src/muscle_tab.c (muscle_init): NULL is a better default than
16407 2001-12-10 Akim Demaille <akim@epita.fr>
16409 * src/reader.c (reader): Calling symbols_output once is enough.
16411 2001-12-10 Akim Demaille <akim@epita.fr>
16413 Now that states have a complete set of members, the linked list of
16414 reductions is useless: just fill directly the state's reductions
16417 * src/state.h (struct reductions): Remove member `number' and
16419 * src/LR0.c (first_reduction, last_reduction): Remove.
16420 (save_reductions): Don't link the new reductions, store them in
16422 * src/lalr.c (set_state_table): No need to attach reductions to
16423 states, it's already done.
16424 * src/output.c (output_actions): No longer free the shifts, then
16425 the reductions, then the states: free all the states and their
16428 2001-12-10 Akim Demaille <akim@epita.fr>
16430 * src/options.c (OPTN, DRTV, BOTH): New.
16431 (option_table): Use them.
16433 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
16434 the job of system.h.
16435 * src/options.c: Don't include stdio.h and xalloc.h for the same
16438 2001-12-10 Akim Demaille <akim@epita.fr>
16440 * src/output.c (output, prepare): Make sure the values of the
16441 muscles `action' and `prologue' are 0-terminated.
16443 2001-12-10 Akim Demaille <akim@epita.fr>
16445 Clean up GCC warnings.
16447 * src/reader.c (copy_action): `buf' is not used.
16448 (parse_skel_decl): Be static.
16449 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
16450 * src/options.h (create_long_option_table): Have a real prototype.
16451 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
16452 (hash_delete_at): Return const void *.
16453 Adjust casts to preserve the const.
16455 2001-12-10 Akim Demaille <akim@epita.fr>
16457 * configure.in: Require 2.52g.
16458 M4 is not needed, but AUTOM4TE is.
16459 * m4/m4.m4: Remove.
16460 * tests/Makefile.am: Adjust.
16462 2001-12-10 Akim Demaille <akim@epita.fr>
16464 One structure for states is enough, even though theoretically
16465 there are LR(0) states and LALR(1) states.
16467 * src/lalr.h (state_t): Remove.
16468 (state_table): Be state_t **, not state_t *.
16469 * src/state.h (core, CORE_ALLOC): Rename as...
16470 (state_t, STATE_ALLOC): this.
16471 Add the LALR(1) members: shifts, reductions, errs.
16472 * src/LR0.c (state_table): Rename as...
16473 (state_hash): this, to avoid name clashes with the global
16475 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
16476 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
16478 2001-12-10 Akim Demaille <akim@epita.fr>
16480 Bison dumps core on bash.y.
16481 Reported by Pascal Bart.
16483 * src/warshall.c (bitmatrix_print): New.
16485 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
16486 j must be the outer loop.
16487 * tests/regression.at (Broken Closure): New.
16489 2001-12-05 Akim Demaille <akim@epita.fr>
16491 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
16493 Reported by Peter Hamorsky.
16495 2001-12-05 Akim Demaille <akim@epita.fr>
16497 * src/conflicts.c (err_table): Remove.
16498 (resolve_sr_conflict): Adjust.
16499 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
16501 (state_t.reductions, state_t.shifts): this.
16503 2001-12-05 Akim Demaille <akim@epita.fr>
16505 * src/reduce.c (reduce_grammar_tables): No longer disable the
16506 removal of useless rules via CPP but via `if (0)', so that the
16507 compiler still check the code is valid.
16508 For instance, it should have noticed `rline' no longer exists: use
16509 the `line' member of rule_t.
16510 * src/gram.c (dummy, rline): Remove, unused.
16512 2001-12-05 Akim Demaille <akim@epita.fr>
16514 * src/output.c (pack_vector): Use assert, not berror.
16515 * src/main.c (berror): Remove, unused.
16517 2001-12-05 Akim Demaille <akim@epita.fr>
16519 New experimental feature: if --verbose --trace output all the
16520 items of a state, not only its kernel.
16522 * src/print.c (print_core): If `trace_flag', then invoke closure
16523 before outputting the items of the state (print_core is no longer
16524 a correct name them).
16525 (print_results): Invoke new_closure/free_closure if needed.
16527 2001-12-05 Akim Demaille <akim@epita.fr>
16529 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
16530 * src/closure.c, src/closure.h (itemsetsize): Rename as...
16531 (nitemset): for consistency with the rest of the project.
16533 2001-12-05 Akim Demaille <akim@epita.fr>
16535 * src/closure.c (print_closure): Improve.
16536 (closure): Use it for printing input and output.
16538 2001-12-05 Akim Demaille <akim@epita.fr>
16540 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
16541 indexed by nonterminals.
16543 2001-12-05 Akim Demaille <akim@epita.fr>
16545 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
16547 * src/warshall.h: Remove accidental duplication of the content.
16549 2001-12-05 Akim Demaille <akim@epita.fr>

16561 2001-12-05 Akim Demaille <akim@epita.fr>
16563 * src/output.c (action_row): De-obfuscate
16564 using the good o' techniques: arrays not pointers, variable
16565 locality, BITISSET, RESETBIT etc.
16567 2001-12-05 Akim Demaille <akim@epita.fr>
16569 Pessimize the code to simplify it: from now on, all the states
16570 have a valid SHIFTS, which NSHIFTS is possibly 0.
16572 * src/LR0.c (shifts_new): Be global and move to..
16573 * src/state.c, src/state.h: here.
16574 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
16575 * src/print_graph: Adjust.
16577 2001-12-05 Akim Demaille <akim@epita.fr>
16579 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
16580 * src/conflicts.c: Use it.
16581 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
16582 incorrectly ``simplified''.
16584 2001-12-05 Akim Demaille <akim@epita.fr>
16586 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
16587 using the good o' techniques: arrays not pointers, variable
16588 locality, BITISSET, RESETBIT etc.
16590 2001-12-05 Akim Demaille <akim@epita.fr>
16592 * src/state.h (SHIFT_SYMBOL): New.
16593 * src/conflicts.c: Use it to deobfuscate.
16595 2001-12-05 Akim Demaille <akim@epita.fr>
16597 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
16598 (print_reductions): De-obfuscate using the good o' techniques:
16599 arrays not pointers, variable locality, BITISSET.
16601 2001-12-05 Akim Demaille <akim@epita.fr>
16603 * src/conflicts.c (print_reductions): Arrays, not pointers.
16606 2001-12-05 Akim Demaille <akim@epita.fr>
16608 * src/conflicts.c (print_reductions): Pessimize, but clarify.

16622 2001-12-05 Akim Demaille <akim@epita.fr>
16624 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

16638 2001-12-05 Akim Demaille <akim@epita.fr>
16640 * src/lalr.c (maxrhs): Move to...
16641 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
16642 * src/lalr.c (build_relations): Adjust.
16644 2001-12-05 Akim Demaille <akim@epita.fr>
16646 * src/lalr.c (transpose): Free the memory allocated to the
16647 argument, as it is replaced by the results by the unique caller.
16648 (build_relations): Merely invoke transpose: it handles the memory
16650 Improve variable locality.
16651 Avoid variables used as mere abbreviations.
16652 (compute_lookaheads): Use arrays instead of pointers.
16654 2001-12-05 Akim Demaille <akim@epita.fr>
16656 * src/lalr.c (initialize_F): Improve variable locality.

16672 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
16673 the handling of squeue.
16674 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16676 2001-12-05 Akim Demaille <akim@epita.fr>
16678 Because useless nonterminals are now kept alive (instead of being
16679 `destroyed'), we now sometimes examine them, and store information
16680 related to them. Hence we need to know their number, and adjust
16681 memory allocations.
16683 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
16685 * src/LR0.c (allocate_itemsets): The memory allocated to
16686 `symbol_count' was used for two different purpose: once to count
16687 the number of occurrences of each symbol, and later reassigned to
16688 `shift_symbol', containing the symbol that can be shifted from a
16690 Deobfuscate, i.e., allocate, use and free `symbol_count' here
16692 (new_itemsets): Allocate `shift_symbol' here.
16693 (allocate_itemsets): symbol_count includes useless nonterminals.
16694 Make room for them.
16695 (free_storage): Use `free', not `XFREE', for pointers that cannot
16698 2001-12-05 Akim Demaille <akim@epita.fr>

16706 * src/gram.c, src/gram.h (ritem_print): New.
16707 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
16708 (This useless function was defined only to work around VMS linkers
16709 that can't handle compilation units with variables only).
16710 * src/reduce.c (dump_grammar): Use it to trace the construction of
16713 2001-12-04 Paul Eggert <eggert@twinsun.com>
16715 * src/bison.simple (union yyalloc): Change member names
16716 to be the same as the stack names.
16717 (yyparse): yyptr is now union yyalloc *, not char *.
16718 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
16719 and may generate better code on some machines.
16720 (yystpcpy): Use prototype if __STDC__ is defined, not just
16721 if __cplusplus is defined.
16723 2001-11-30 Akim Demaille <akim@epita.fr>
16725 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
16726 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
16727 Gettext doesn't compile cleanly, and dies with -Werror.
16728 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
16729 Include WARNING_CFLAGS here.
16730 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
16731 before being defined.

16735 * lib/quotearg.h (quotearg_n, quotearg_n_style):
16736 First arg is int, not unsigned.
16737 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
16738 (SIZE_MAX, UINT_MAX): New macros.
16739 (quotearg_n_options): Abort if N is negative.
16740 Avoid overflow check on hosts where size_t is 64 bits and int
16741 is 32 bits, as overflow is impossible there.
16742 Fix off-by-one typo that caused unnecessary reallocation.
16744 2001-11-29 Paul Eggert <eggert@twinsun.com>
16746 Name space cleanup in generated parser.
16748 * doc/bison.texinfo (Bison Parser): Discuss system headers
16749 and their effect on the user name space.
16751 * src/bison.simple:
16752 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
16753 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
16754 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
16756 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
16757 on user names when possible.
16759 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
16760 Simplify test for whather <alloca.h> exists.
16762 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
16764 (<stdio.h>): Include if YYDEBUG.
16766 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
16767 ! defined (yyoverflow) && ! defined (yymemcpy).
16769 (yymemcpy, yyparse): Rename local variables as needed so that
16770 they all begin with 'yy'.
16772 (yystrlen, yystpcpy): New functions.
16774 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
16777 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
16778 instead of relying on string.h functions. Use YYSTACK_ALLOC
16779 and YYSTACK_FREE instead of malloc and free.
16781 2001-11-30 Akim Demaille <akim@epita.fr>
16783 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
16784 before their first uses.

16794 if body instead of `;' to pacify GCC's warnings.
16796 2001-11-30 Akim Demaille <akim@epita.fr>
16798 Instead of mapping the LHS of unused rules to -1, keep the LHS
16799 valid, but flag the rules as invalid.
16801 * src/gram.h (rule_t): `useful' is a new member.
16802 * src/print.c (print_grammar): Adjust.
16803 * src/derives.c (set_derives): Likewise.
16804 * src/reader.c (packgram, reduce_output): Likewise.
16805 * src/reduce.c (reduce_grammar_tables): Likewise.

16822 2001-11-30 Akim Demaille <akim@epita.fr>

16832 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
16833 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
16835 (union yyalloc): New type.
16836 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
16837 an arbitrary restriction on hosts where size_t is wider than int.
16839 (yyparse): Don't dump core if alloca or malloc fails; instead, report
16840 a parser stack overflow. Allocate just one block of memory for all
16841 three stacks, instead of allocating three blocks; this typically is
16842 faster and reduces fragmentation.
16844 Do not limit the number of items in the stack to a value that fits
16845 in 'int', as this is an arbitrary limit on hosts with 64-bit
16846 size_t and 32-bit int.
16848 2001-11-29 Marc Autret <autret_m@epita.fr>
16850 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
16851 of defining YYERROR_VERBOSE.
16852 [AT_DATA]: $4 is now out of C declarations in the prologue.
16854 2001-11-28 Marc Autret <autret_m@epita.fr>

16898 * src/closure.c (closure): `b' and `ruleno' denote the same value:
16901 2001-11-28 Akim Demaille <akim@epita.fr>
16903 * src/closure.c (closure): Instead of looping over word in array
16904 then bits in words, loop over bits in array.
16906 2001-11-28 Akim Demaille <akim@epita.fr>
16908 * src/closure.c (closure): No longer optimize the special case
16909 where all the bits of `ruleset[r]' are set to 0, to make the code

16924 * src/reduce.c (dump_grammar): Don't translate trace messages.
16926 2001-11-28 Akim Demaille <akim@epita.fr>
16928 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
16929 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

16933 2001-11-27 Paul Eggert <eggert@twinsun.com>
16935 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

17021 conflicts as expected.
17022 * tests/regression.at (%expect right): Adjust.
17024 2001-11-23 Akim Demaille <akim@epita.fr>

18682 * src/lex.h: Rename all the tokens:
18683 s/\bENDFILE\b/tok_eof/g;
18684 s/\bIDENTIFIER\b/tok_identifier/g;
18686 Let them be enums, not #define, to ease debugging.

18691 * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
18692 * src/lex.c (maxtoken, grow_token_buffer): Static.
18694 2001-01-18 Akim Demaille <akim@epita.fr>
18696 Since we now use obstacks, more % directives can be enabled.
18698 * src/lex.c (percent_table): Also accept `%yacc',
18699 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
18701 Handle the actions for `%semantic_parser' and `%pure_parser' here,

18704 * src/reader.c (read_declarations): Adjust.
18705 * src/files.c (open_files): Don't call `compute_base_names', don't

18709 * src/output.c (output_headers): Document the fact that this patch
18710 introduces a guaranteed SEGV for semantic parsers.

18721 * src/conflicts.c: Return a string.
18722 * src/system.h (obstack_grow_string): Rename as...
18723 (obstack_sgrow): this. Be ready to work with non literals.
18724 (obstack_fgrow4): New.
18726 2000-12-20 Akim Demaille <akim@epita.fr>
18728 * src/files.c (open_files): Fix the computation of short_base_name
18729 in the case of `-o foo.tab.c'.

18779 (obstack_grow_string): this.
18780 * src/output.c (output_parser): Recognize `%% actions' instead of

18812 2000-12-19 Akim Demaille <akim@epita.fr>
18814 * src/files.c (open_files): Yipee! We no longer need all the code
18815 looking for `/tmp' since we have no tmp file.
18817 2000-12-19 Akim Demaille <akim@epita.fr>
18819 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

18826 Provide a default definition.
18827 Use it when executing the default @ action.

18844 2000-11-17 Akim Demaille <akim@epita.fr>
18846 * lib/obstack.h: Formatting changes.
18847 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
18848 prevents type checking.
18849 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
18850 cast the value to (void *): assigning a `foo *' to a `void *'

18872 Use them to declare the variables which are global or local to
18875 2000-11-17 Akim Demaille <akim@epita.fr>
18877 * acconfig.h: Remove, no longer used.
18879 2000-11-07 Akim Demaille <akim@epita.fr>
18881 * src: s/Copyright (C)/Copyright/g.
18883 2000-11-07 Akim Demaille <akim@epita.fr>
18885 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
18887 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
18889 2000-11-07 Akim Demaille <akim@epita.fr>
18891 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

18897 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
18898 argument `data' for consistency with the prototypes.
18899 Qualify it `const'.
18900 (obstack_copy, obstack_copy0): Rename the second argument as
18901 `address' for consistency. Qualify it `const'.
18902 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
18903 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
18904 `const' their input argument (`data' or `address').
18905 Adjust the corresponding macros to include `const' in casts.
18907 2000-11-03 Akim Demaille <akim@epita.fr>
18909 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
18910 s/PFILE1/BISON_HAIRY/.
18911 Adjust dependencies.
18913 2000-11-03 Akim Demaille <akim@epita.fr>
18915 For some reason, this was not applied.
18917 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
18918 `unlink': it's no longer used.
18920 2000-11-03 Akim Demaille <akim@epita.fr>
18922 * src/files.c (skeleton_find): New function, eved out of...

18927 Don't use `atexit'.
18929 * src/files.c (obstack_save): New function.
18930 (done): Rename as...
18931 (output_files): this.
18932 Use `obstack_save'.
18933 * src/main.c (main): Don't use `atexit' to register `done', since
18934 it no longer has to remove tmp files, just call `output_files'
18935 when there are no errors.
18937 2000-11-02 Akim Demaille <akim@epita.fr>
18939 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
18940 `unlink': it's no longer used.
18941 * src/files.h: Formatting changes.
18943 2000-11-02 Akim Demaille <akim@epita.fr>
18945 Remove the last uses of mktemp and unlink/delete.
18947 * src/files.c (fdefines, ftable): Removed.
18948 (defines_ostack, table_obstack): New.
18949 Adjust dependencies of the former into uses of the latter.
18950 * src/output.c (output_short_or_char_table, output_short_table):

18970 Introduce obstacks.
18971 Change each use of `faction' into a use of `action_obstack'.
18973 * lib/obstack.h, lib/obstack.c: New files.
18974 * src/files.c (faction): Remove.
18975 (action_obstack): New.
18976 Adjust all dependencies.
18978 2000-10-20 Akim Demaille <akim@epita.fr>
18980 * lib/quote.h (PARAMS): New macro. Use it.
18982 2000-10-16 Akim Demaille <akim@epita.fr>
18984 * src/output.c (output_short_or_char_table): New function.
18985 (output_short_table, output_token_translations): Use it.

18999 2000-10-16 Akim Demaille <akim@epita.fr>
19001 * src/lex.c (read_typename): New function.
19003 * src/reader.c (copy_dollar): Likewise.
19005 2000-10-16 Akim Demaille <akim@epita.fr>
19007 * src/reader.c (copy_comment2): Expect the input stream to be on
19008 the `/' which is suspected to open a comment, instead of being
19009 called after `//' or `/*' was read.
19010 (copy_comment, copy_definition, parse_union_decl, copy_action)
19011 (copy_guard): Adjust.
19013 2000-10-16 Akim Demaille <akim@epita.fr>
19015 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
19016 `read_signed_integer'.
19018 2000-10-16 Akim Demaille <akim@epita.fr>
19020 * src/reader.c (copy_dollar): New function.
19021 (copy_guard, copy_action): Use it.
19023 2000-10-16 Akim Demaille <akim@epita.fr>
19025 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
19026 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
19027 New files, from Fileutils 4.0.27.
19028 * src/main.c (printable_version): Remove.
19029 * src/lex.c, src/reader.c: Use `quote'.
19031 2000-10-04 Akim Demaille <akim@epita.fr>
19033 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
19035 2000-10-04 Akim Demaille <akim@epita.fr>
19037 * doc/bison.texinfo: Various typos spotted by Neil Booth.
19039 2000-10-04 Akim Demaille <akim@epita.fr>
19041 When a literal string is used to define two different tokens,
19042 `bison -v' segfaults.
19043 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
19045 * tests/regression.m4: New file.
19046 Include the core of the sample provided by Piotr Gackiewicz.
19047 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
19050 2000-10-04 Akim Demaille <akim@epita.fr>
19052 * src/reader.c (parse_expect_decl): Keep `count' within the size
19056 2000-10-02 Paul Eggert <eggert@twinsun.com>
19058 * bison.s1 (yyparse): Assign the default value
19059 unconditionally, to avoid a GCC warning and make the parser a
19062 2000-10-02 Akim Demaille <akim@epita.fr>
19064 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
19067 2000-10-02 Akim Demaille <akim@epita.fr>
19069 * src/derives.c, src/print.c, src/reduce.c: To ease the
19070 translation, move some `\n' out of the translated strings.
19072 2000-10-02 Akim Demaille <akim@epita.fr>
19074 The location tracking mechanism is precious for parse error
19075 messages. Nevertheless, it is enabled only when `@n' is used in
19076 the grammar, which is a different issue (you can use it in error
19077 message, but not in the grammar per se). Therefore, there should
19078 be another means to enable it.
19080 * src/getargs.c (getargs): Support `--locations'.
19081 (usage): Report it.
19082 * src/getargs.h (locationsflag): Export it.
19083 * src/lex.c (percent_table): Support `%locations'.
19084 * src/reader.c (yylsp_needed): Remove this variable, now replaced
19085 with `locationsflag'.
19086 * doc/bison.texinfo: Document `--locations' and `%locations'.
19088 * tests/calc.m4: Test it.
19090 For regularity of the names, replace each
19091 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
19092 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
19093 In addition replace each `flag' with `_flag'.
19095 2000-10-02 Akim Demaille <akim@epita.fr>
19097 Also test parse error messages, including with YYERROR_VERBOSE.
19099 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
19101 Use it to check the computations.
19102 Use it to check `nonassoc' is honored.
19103 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
19104 `--yyerror-verbose'.
19105 (_AT_CHECK_CALC): Adjust to this option.
19106 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
19108 2000-10-02 Akim Demaille <akim@epita.fr>
19110 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19111 the latter demonstrates a flaw in the handling of non debugging
19112 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19113 was used in order to simplify:
19129 unfortunately this leads to a CPP conflict when
19130 `--name-prefix=foo' is used since it produces `#define yydebug
19133 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
19134 (YYDPRINTF): New macro.
19136 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
19138 Also test `--verbose', `--defines' and `--name-prefix'.
19140 2000-10-02 Akim Demaille <akim@epita.fr>
19142 Improve the readability of the produced parsers.
19144 * src/bison.s1: Formatting changes.
19145 Improve the comment related to the `$' mark.
19146 (yydefault): Don't fall through to `yyresume': `goto' there.
19147 * src/output.c (output_parser): When the `$' is met, skip the end
19149 New variable, `number_of_dollar_signs', to check there's exactly
19150 one `$' in the parser skeleton.
19152 2000-10-02 Akim Demaille <akim@epita.fr>
19154 * lib/xstrdup.c: New file, from the fileutils.
19155 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
19156 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
19157 instead of strlen + xmalloc + strcpy.
19158 * src/symtab.c (copys): Remove, use xstrdup instead.
19160 2000-10-02 Akim Demaille <akim@epita.fr>
19162 * src/gram.h (associativity): New enum type which replaces the
19163 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
19164 `right_assoc', `left_assoc' and `non_assoc'.
19165 Adjust all dependencies.
19166 * src/reader.c: Formatting changes.
19167 (LTYPESTR): Don't define it, use it as a literal in
19168 `reader_output_yylsp'.
19169 * src/symtab.h (symbol_class): New enum type which replaces the
19170 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
19171 `sunknown', `stoken and `snterm'.
19173 2000-10-02 Akim Demaille <akim@epita.fr>
19175 * src/getargs.c (fixed_outfiles): Rename as...
19176 (yaccflag): for consistency and accuracy.
19177 Adjust dependencies.
19179 2000-10-02 Akim Demaille <akim@epita.fr>
19181 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19182 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19183 difficult and introduced a lot of core dump. It turns out that
19184 Bison used an implementation of `xmalloc' based on `calloc', and
19185 at various places it does depend upon the initialization to 0. I
19186 have not tried to isolate the pertinent places, and all the former
19187 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
19188 someone should address this issue.
19190 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
19191 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
19193 Adjust dependencies.
19194 * src/warshall.h: New file.
19197 2000-10-02 Akim Demaille <akim@epita.fr>
19199 Various anti-`extern in *.c' changes.
