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

97 Fix some .gitignore and .cvsignore problems.
98 * bootstrap (insert_sorted_if_absent): Replace all uses with...
99 (insert_vc_ignore): ... this new function, which prepends `/' to all
100 .gitignore entries before passing them to insert_sorted_if_absent.
101 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
102 .cvsignore files are maintained even though Bison developers run
103 bootstrap while using Git.

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

190 Revert prior patch, by working around autoconf regression.
191 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
192 ("Output file name: ("): Uncomment test.
193 ("Output file name: )"): Likewise.
194 Based on an idea from Noah Misch.

212 Update to the current gnulib CVS repository, and fix trigraph handling
214 * bootstrap: Update gnulib CVS repository URL.
215 (symlink_to_dir): Encapsulate the code that guarantees the destination
216 directory exists into...
217 (check_dst_dir): ... this new function, and...
218 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
219 fail when copying files into lib/uniwidth/.
220 * src/output.c (prepare_symbols): When writing yytname muscles, where
221 symbol names will be encoded in C-string literals, tell quotearg to
222 escape trigraphs. This used to be the default in gnulib.
223 * tests/regression.at (Token definitions): Because of the change in
224 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
225 escapes trigraphs in symbol names. Thus, yytname no longer has
226 trigraphs unnecessarily doubly escaped. Update test case output.
227 Extend test case to be sure Bison's own error messages will no longer
228 have trigraphs in symbol names unnecessarily escaped once.
230 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>

243 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
244 consistency. Update the -g and -x entries now that they take
245 arguments. Use brackets to indicate optional arguments.
246 * src/getargs.c (usage): Explain the relationship between arguments of
247 long and short options more completely. Document --defines and -d
248 separately since the former takes an argument but, for POSIX Yacc, the
250 (short_options): Let -W take an optional argument like --warnings.
251 (getargs): Sort cases.
253 2008-02-28 Akim Demaille <demaille@gostai.com>

266 * build-aux/cross-options.pl: Use /x to make the regexp easier to
268 Fix the handling of $opt which resulted in all the argument to be
269 considered as optional.

311 check impure push parsers without the pull interface.
313 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since

989 Replace `%push-parser' and `%push-pull-parser' with
990 `%define push_pull "push"' and `%define push_pull "both"'.
991 `%define push_pull "pull"' is the default.

1004 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
1005 parsing requests here...
1006 * data/yacc.c: ... hack this to switch to push.c any time
1007 b4_use_push_pull_flag or the %define variable push_pull is set. This
1008 will go away when we mv push.c yacc.c.
1009 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
1010 push parsing is not supported since unused %define variables are

1044 * src/conflicts.c (log_resolution): Fix indenting bugs I introduced.
1045 Problem reported by Wojciech Polak.
1046 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.
1047 (xml_printf): Undo change I made on 21 September; that is,
1048 indent 2 spaces, not 1.
1050 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
1052 Pacify ./configure --enable-gcc-warnings.
1053 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
1054 `char const *' instead of `char *'.
1055 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
1056 local variable `sep'.
1058 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
1060 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
1062 * src/print-xml.c: Prefer "const" after types; that's more consistent.
1063 (xml_printf): Indent just 1 space for level.
1064 (e_char, xlate_char): Remove.
1065 (xml_escape_string): Rewrite to avoid undefined behavior (used
1066 storage that was freed from the stack).
1067 (xml_escape_n): Don't bother checking for subscript error.
1069 2007-09-21 Wojciech Polak <polak@gnu.org>

1118 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
1119 Bruno Haible <bruno@clisp.org>
1121 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
1122 and is a script that invokes bison. Tighten the code. Add comments.
1124 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

1132 defaults): Rename to...
1133 (%define Boolean variables: invalid skeleton defaults): ... this and
1136 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
1138 In impure push mode, don't allow more than one yypstate to be allocated
1139 since multiple impure parsers would corrupt yynerrs.
1140 * data/push.c (yypstate_allocated): New static global variable
1142 (yypull_parse): If yypstate_new returns 0, don't report it as memory
1143 exhaustion if yypstate_allocated is 1, but still return 2.
1144 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
1145 already 1. Otherwise, set it to 1.
1146 (yypstate_delete): Set it to 0.

1221 Get rid of broken %no-parser, -n, and --no-parser implementation and
1223 * TODO: Don't mention them.
1224 * doc/bison.1: Likewise.
1225 * doc/bison.texinfo (Decl Summary): Likewise.
1226 (Bison Options): Likewise.
1227 (Option Cross Key): Likewise.
1228 * src/getargs.c (no_parser_flag): Remove global variable.
1229 (usage): Don't print description of -n and --no-parser.
1230 (long_options): Remove --no-parser entry here.
1231 (getargs): Remove -n case in the switch here.
1232 * src/getargs.h (no_parser_flag): Remove extern.
1233 * tests/regression.at (Web2c Actions): Remove comment that mentions
1236 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
1238 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
1239 name user variables starting with `yy'. Just pass NULL instead of a
1240 dummy local &yylval to yypush_parse.
1241 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
1244 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
1246 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
1247 true since it's then always used regardless of whether yyoverflow is
1248 defined. Reported by Christian Burger at
1249 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
1250 * THANKS: Add Christian Burger.
1252 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1253 node names: say "Decl Summary" not "Bison Declaration Summary".
1255 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
1257 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
1258 determine whether this function has already complained about an invalid
1259 value for a %define boolean variable, don't check whether Bison has
1260 ever examined the value. As written, the check was a tautology.
1261 Instead, record and check for this complaint using a separate muscle.
1263 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
1265 Fix push parsing memory leak reported by Brandon Lucia at
1266 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
1267 * THANKS: Add Brandon Lucia.
1268 * data/push.c (yypstate_delete): Free the stack if it was reallocated
1269 but the parse never completed and thus freed it.
1270 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
1271 * tests/testsuite.at: Include push.at.
1272 * test/push.at: New.
1273 (Push Parsing: Memory Leak for Early Deletion): New test case.
1275 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
1277 Improve handling of multiple S/R conflicts in the same state and of S/R
1278 conflicts involving multiple reductions.
1279 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
1280 set for a state here or Bison will abort if it is reassigned on a
1281 later conflicted reduction in the same state.
1282 Similarly, don't finalize and assign the solved conflicts report here
1283 or it will be lost if it is reassigned on a later conflicted reduction
1285 (set_conflicts): Instead, assign them both here after all S/R conflicts
1286 in the state have been fully examined.
1287 * src/print.c (shift_set): Rename to...
1288 (no_reduce_set): ... this.
1289 (print_reductions): Update for rename, and add %nonassoc error action
1290 tokens to no_reduce_set so that, when printing the first remaining
1291 reduction on an error action token, the reduction is enclosed in
1293 (print_results): Update for rename.
1294 * tests/conflicts.at (Solved conflicts report for multiple reductions
1295 in a state): New test case.
1296 (%nonassoc error actions for multiple reductions in a state): New test
1299 * src/main.c (main): Don't depend on C99 features.
1301 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
1303 * build-aux/.cvsignore: Add compile.
1304 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
1307 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
1309 * bootstrap (slurp): Create target directories that don't exist.
1310 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
1312 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
1314 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
1316 * closure.c (closure): Likewise.
1317 * state.h (reductions): Comment sorting of rules.
1318 (state): Comment sorting of items.
1320 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
1322 Fix C++ test cases after recent Gnulib changes. Discussed starting at
1323 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
1324 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
1325 definition in order to avoid Gnulib headers since we don't use config.h
1327 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
1328 rather than AT_DATA so that config.h is included.
1330 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
1332 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
1333 instead of fprintf. Guard these functions with #if YYDEBUG instead of
1334 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
1335 and so that YYFPRINTF is guaranteed to be defined here.
1337 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
1339 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
1341 (muscle_percent_define_check_values): ... this more helpful function.
1342 Again, it's not used yet, but it will be.
1343 * src/muscle_tab.h: Likewise.
1345 Improve some comments in parser table construction.
1346 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
1347 (generate_states): Don't mention ruleset, which is internal to closure.
1348 * src/closure.c (closure): Explain sorting of core and itemset, which
1349 is required for this function to behave correctly.
1350 * src/closure.h (closure): Mention sorting.
1352 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
1354 * src/lalr.c (state_lookahead_tokens_count): For code readability,
1355 move the check for disabled transitions to an aver since conflict
1356 resolution hasn't happened yet.
1358 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
1359 labels a state as inconsistent just because it has error transitions.
1360 The original form of this check appeared in revision 1.1 of lalr.c,
1361 which was committed on 1991-12-21. Now (at least), changing the
1362 consistency label on such a state appears to have no useful effect in
1363 any of the places it is examined, which I enumerate below. The key
1364 point to understanding each item in this enumeration is that a state
1365 with an error transition is labelled consistent in the first place only
1366 if it has no rules, so the check cannot matter for states that have
1367 rules. (1) Labelling a state as inconsistent will cause set_conflicts
1368 to try to identify its conflicts, and a state must have *rules* to have
1369 conflicts. (2) Labelling a state as inconsistent will affect how
1370 action_row sets the default *rule* for the state. (3) Labelling a
1371 state as inconsistent will cause build_relations to add lookback edges
1372 to *rules* in that state.
1373 * src/state.h (struct state): Word the comment for member consistent
1376 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
1378 Don't depend on C99 features.
1379 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
1380 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
1381 * src/reader.c (check_and_convert_grammar): Fix for-loop.
1382 * src/state.c (state_mark_reachable_states): Fix for-loop.
1383 (state_remove_unreachable_states): Fix for-loop.
1385 Don't widen struct state with member reachable just to temporarily
1386 record reachability. Instead, use a local bitset.
1387 * src/state.h (struct state): Remove member.
1388 * src/state.c (state_new): Don't initialize it.
1389 (state_mark_reachable_states): Rename to...
1390 (state_record_reachable_states): ... this, and use bitset.
1391 (state_remove_unreachable_states): Use bitset.
1393 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
1395 * src/Makefile.am (yacc): Quote target action commands properly so
1396 that the yacc script isn't corrupt. Reported by Hans Aberg at
1397 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
1399 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
1400 the case of pure parsers. Reported by Frans Englich at
1401 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
1402 * THANKS: Add Frans Englich.

1629 Undo my 2007-02-07 change, switching back to the c-strcase module
1630 introduced in the 2007-02-03 change. Bruno Haible reported that
1631 the 2007-02-07 change would be dangerous in Turkish if we add a
1632 language whose name contains "i", since "i" is not lowercase "I"
1634 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
1635 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
1636 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
1637 * m4/.cvsignore: Remove strcase.m4.
1638 * src/getargs.c: Revert 2007-02-07 change, as follows.
1639 Include c-strcase.h.
1640 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
1642 2007-02-11 Bruno Haible <bruno@clisp.org>
1644 Enable the Java related testsuite tests when the only Java compiler
1645 found is a gcj < 4.3. Discussed at
1646 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
1647 * configure.ac (gt_JAVACOMP): Don't specify a target_version.

1655 * src/reader.c (packgram): Move translation of rule actions from the
1656 beginning of packgram to...
1657 (check_and_convert_grammar): ... here right before packgram is invoked
1658 so it's easier to write more complete comments, and remove redundant
1661 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
1663 As in semantic actions, make @$ in %initial-action, %destructor, and
1664 %printer imply %locations.
1665 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
1667 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
1668 (@$ in %initial-action implies %locations,
1669 @$ in %destructor implies %locations,
1670 @$ in %printer implies %locations): ... these new test cases.
1672 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
1674 Undo most of the 2007-02-03 change, switching to the strcase module
1675 now that gnulib strcase has been fixed.
1676 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
1677 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
1678 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
1679 * m4/.cvsignore: Add strcase.m4.
1680 * src/getargs.c: Revert 2007-02-03 change, as follows.
1681 Don't include c-strcase.h.
1682 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
1683 strcasecmp has "unspecified behavior" outside the POSIX locale,
1684 but it works fine in practice if at least one argument is ASCII,
1685 as is the case in Bison.
1687 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
1689 * tests/java.at: Skip tests if only one of javac/java is present.
1690 Reported by Joel E. Denny.
1691 * tests/atlocal.in: Adjust copyright years.
1693 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
1695 * data/lalr1.java (Stack): Work around old verifiers that disallow
1696 access to the private fields of an inner class, from the outer class.
1697 We can make Stack's fields public because user code doesn't have access
1698 to the instance of Stack used by parse(). Reported by Paul Eggert.
1700 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1702 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
1703 the right spot for these files?
1704 * bootstrap.conf (gnulib_modules): Add c-strcase.
1705 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
1707 * src/getargs.c: Include c-strcase.h.
1708 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
1709 to avoid unspecified behavior.
1711 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
1713 * doc/bison.texinfo (Decl Summary): Correct typo.
1715 2007-01-30 Paolo Bonzini <bonzini@gnu.org>

1719 * data/c++.m4: Adjust default definitions of %define variables.
1720 * data/java.m4: Adjust default definitions of %define variables.
1721 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according

1742 * src/getargs.h (struct bison_language): Update size of string fields.
1744 * tests/Makefile.am: Add java.at.
1745 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
1746 * tests/java.at: New.
1747 * tests/testsuite.at: Include it.
1749 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
1752 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
1753 at_directive_argv arguments so these no longer have to be global
1754 variables. Also, update the implementation for the following changes.
1755 (fail_for_at_directive_too_many_args,
1756 fail_for_at_directive_too_few_args): Add at_directive_name argument.
1757 (at_directive_name): Remove as at_directive_argv[0] will be used for
1759 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
1760 for the directive name.

1764 (SC_AT_DIRECTIVE_ARG): Rename to...
1765 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
1766 (SC_AT_DIRECTIVE_SKIP_WS): Update.
1767 (scan_skel): Move yylex_destroy to...
1768 (skel_scanner_free): ... here.
1769 * tests/skeletons.at (installed skeleton file name): Rename to...
1770 (installed skeleton file names): ... this.
1772 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
1774 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1775 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
1776 Summary" not "Directives".
1777 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
1778 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
1779 since the former is now the more complete one.
1780 (Prologue Alternatives): Likewise and do the same for %defines.
1781 (Table of Symbols): Add summary of %code, add summary of %define, and
1782 move full %code documentation to...
1783 (Decl Summary): ... here for consistency with other entries in these
1785 Move %define entry in order to keep this list alphabetized.
1786 Reword %define entry a little to put less emphasis on the skeleton
1787 concept, which most users shouldn't have to think about.
1789 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
1791 Adjust to recent gnulib changes.

1800 Simplify implementation of unqualified %code, implement macros for
1801 uniform treatment of boolean %define flags. Document %define.

1858 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
1860 (Calc++ Scanner): Exit with failure if we can't open the input
1862 Accept "-" standing for stdin.
1863 (Calc++ Top Level): Print the result only if the parsing was
1866 2007-01-16 Akim Demaille <akim@epita.fr>
1868 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
1870 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
1871 and Joel E. Denny <jdenny@ces.clemson.edu>
1873 Clean up %define and %code implementation in M4 some. Most
1874 importantly, rename all related macros to be in the b4_percent_define
1875 and b4_percent_code namespaces. Also, complete support for `.' in
1876 %define variable names and %code qualifiers.
1877 * data/bison.m4 (b4_check_user_names): Check for special
1878 "SKELETON-NAMESPACE(name)" macros instead of using two nested
1880 (b4_get_percent_define, b4_get_percent_code): Rename to...
1881 (b4_percent_define_get, b4_percent_code_get): ... these.
1882 Extend documentation with examples.
1883 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
1884 b4_percent_define_skeleton_variables and
1885 b4_percent_code_skeleton_qualifiers.
1886 Expect any value for the %define variable `foo' to be stored in the
1887 macro named `b4_percent_define(foo)'; expect any %code blocks for the
1888 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
1889 expect any unqualified %code blocks to be stored in a macro named
1890 `b4_percent_code_unqualified'.
1891 Use m4_indir so that %define variable names and %code qualifiers can
1892 contain `.', which is allowed by the grammar parser.
1893 (b4_percent_define_default): New macro to set a default value for a
1895 (m4_wrap): Update wrapped code, and fix some underquoting.
1896 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
1897 Expect grammar uses of %define variables and %code qualifiers to be
1898 defined in b4_percent_define_user_variables and
1899 b4_percent_code_user_qualifiers.
1900 * data/c++.m4: Use b4_percent_define_default rather than
1901 m4_define_default. Fix some underquoting. Skeleton usage of %define
1902 variable define_location_comparison now implies skeleton usage of
1903 %define variable filename_type.
1904 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1905 data/push.c, data/yacc.c: Update macro names.
1906 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
1909 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
1911 DJGPP specific issues.
1913 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
1914 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
1916 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1918 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
1919 run parsers in all tests so that Valgrind is invoked during
1920 maintainer-check-valgrind.
1921 (Duplicate representation of merged trees): Free all semantic values.
1922 (Duplicated user destructor for lookahead): Likewise.
1924 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1926 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
1927 command-line prefix.
1928 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
1929 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
1930 miss Valgrind messages.
1931 (Exploding the Stack Size with Malloc): Likewise.
1933 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1935 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
1936 locals. Reported by Juan Manuel Guerrero at
1937 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
1938 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
1939 Fix some indentation also.
1940 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
1941 explaining this issue.
1943 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
1944 and Joel E. Denny <jdenny@ces.clemson.edu>
1946 Simplify union and prologue handling, and escape union and lex/parse
1947 params with digraphs.
1948 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
1949 values to the empty string since these are no longer guaranteed
1950 initialized by the front-end.
1951 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
1952 braces around b4_user_stype since this is no longer done by the
1954 * src/files.c, src/files.h (pre_prologue_obstack,
1955 post_prologue_obstack): Remove.
1956 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
1957 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
1958 with digraphs. This fixes lex params and parse params.
1959 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
1960 * src/output.c (prepare): Remove muscle insertion of the prologues.
1961 (output): Remove freeing of pre_prologue_obstack and
1962 post_prologue_obstack.
1963 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
1964 than prologue_augment for prologue parsing so you don't need prologue
1966 (grammar_declaration): For %union RHS, use `braceless' instead of
1967 "{...}" so that braces are already stripped and code is escaped with
1969 * src/reader.c (prologue_augment): Remove.
1970 (reader): Remove initialization of pre_prologue_obstack and
1971 post_prologue_obstack.
1972 * src/reader.h (prologue_augment): Remove.
1974 * data/c.m4: Remove stray parenthesis.
1976 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1978 Remove quotes from variables names in %define directives and from
1979 qualifiers in %code directives, and restrict the characters that are
1980 allowed in them to M4-friendly ones. For %define, continue to support
1981 the quoted form as a deprecated feature. Discussed starting at
1982 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
1983 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
1985 * doc/bison.texinfo (Prologue Alternatives): Update.
1986 (Decl Summary): In %defines entry, update mention of `%code requires'
1987 and `%code provides'.
1988 (C++ Location Values): Update %define uses.
1989 (Calc++ Parser Interface): Likewise.
1990 (Calc++ Parser): Likewise, and update `%code requires' uses.
1991 (Table of Symbols): Update %code documentation.
1992 * src/parse-gram.y (prologue_declaration): For %define variables, use
1993 `variable' instead of `STRING'.
1994 (grammar_declaration): For %code qualifiers, use `ID' instead of
1996 (variable): New nonterminal that takes an `ID' or a `STRING'.
1997 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
1999 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
2000 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
2001 (%define errors): Update %define uses.
2003 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2005 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
2006 instead of muscle_insert for %define values so that M4-special
2007 characters are replaced with digraphs.
2008 * tests/input.at (%define errors): Extend to check weird values.
2010 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2012 Instead of having skeletons declare all valid %define variables and
2013 %code qualifiers, provide macros that retrieve the associated values
2014 and build these lists automatically. Thus Bison will now warn when a
2015 variable or qualifier is not used by the skeleton in the current
2016 invocation regardless of whether it might sometimes be used by that
2017 skeleton in other invocations. Also, move all %define value macros to
2018 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2019 form, which is replaced by %code.
2020 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2021 (b4_check_user_names): ... this, and change the series of valid name
2022 arguments to a single list argument for names used in the skeleton
2023 similar to the existing list argument for names used in the grammar.
2024 Warn instead of complaining.
2025 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2026 values and %code code, to format %code code properly, and to build
2027 lists of all %define variables and %code qualifiers used in the
2028 skeleton: b4_skeleton_percent_define_variables and
2029 b4_skeleton_percent_code_qualifiers.
2030 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
2032 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
2033 the skeleton names lists can finish building first. In place of
2034 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
2035 expect the lists b4_user_percent_define_variables and
2036 b4_user_percent_code_qualifiers.
2037 * data/c++.m4: Where setting default values for b4_parser_class_name,
2038 b4_location_type, b4_filename_type, b4_namespace, and
2039 b4_define_location_comparison, update their names to the
2040 b4_percent_define_ namespace.
2041 * data/glr.c: Don't use b4_check_percent_define_variables and
2042 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2043 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
2044 (b4_parser_class_name, b4_namespace): Define these using
2045 b4_get_percent_define for parser_class_name and namespace.
2046 * data/location.cc: Use b4_get_percent_define.
2047 * data/push.c: Don't use b4_check_percent_define_variables and
2048 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2049 * data/yacc.c: Likewise, and don't call m4_exit in
2050 b4_use_push_for_pull_if or m4_wrap code will never execute.
2051 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
2053 (muscle_grow_user_name_list): ... this for consistency with the
2054 terminology used in bison.m4.
2055 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
2056 %define variable names, and rename muscle used_percent_define_variables
2057 to user_percent_define_variables.
2058 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
2059 user_percent_code_qualifiers.
2061 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
2062 {CODE} form is no longer accepted.
2063 * tests/input.at (Reject bad %code qualifiers): Rename to...
2064 (Reject unused %code qualifiers): ... this, and update test output.
2065 (%define error): Update test output.
2067 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
2069 Check for unrecognized %define variables similar to checking for
2070 unrecognized %code qualifiers. Check for redefined %define variables.
2071 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
2073 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
2074 (b4_check_percent_define_variables): New, also wraps it.
2075 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
2076 variables using b4_check_percent_define_variables.
2077 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
2078 all those exercised in the test suite and all those listed in the
2079 `Default values' section of c++.m4. Are there others?
2080 * data/push.c, data/yacc.c: Declare no valid %define variables.
2081 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
2082 similar to muscle_find, but it works even when the muscle stores a
2084 (muscle_grow_used_name_list): New function for constructing the used
2085 name list muscles that b4_check_for_unrecognized_names requires.
2086 * src/parse-gram.y (prologue_declaration): Warn if a variable is
2087 %define'd more than once. Define the b4_used_percent_define_variables
2088 muscle with muscle_grow_used_name_list.
2089 (grammar_declaration): Abbreviate %code code with
2090 muscle_grow_used_name_list.
2091 * tests/input.at (%define errors): New.
2093 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2095 Provide warn_at, complain_at, and fatal_at function callbacks to the
2096 skeletons, and use this for %code qualifier complaints.
2097 * data/bison.m4 (b4_error_at): New, invoked by...
2098 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
2099 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
2100 @fatal_at(...@) directives.
2101 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
2102 qualifiers in b4_used_percent_code_qualifiers and to use
2104 * src/location.c, src/location.h (boundary_set_from_string): New global
2106 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
2108 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
2109 to b4_used_percent_code_qualifiers.
2110 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
2112 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
2113 (lineno): Rename to...
2114 (out_lineno): ... this so I don't misunderstand it again.
2115 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
2116 here; these newlines are in the input but not the output file.
2117 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
2118 (at_directive_perform): ... this new static function, and add handling
2119 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
2121 * tests/input.at (Reject bad %code qualifiers): Update test output with
2122 locations and extend.
2124 * tests/output.at (Output file name: [, Output file name: ]): Remove
2125 bogus comment about these tests failing.
2127 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2129 Clean up b4_check_percent_code_qualifiers a little.
2130 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
2131 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
2132 documentation and add examples.
2133 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
2136 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2138 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
2139 unreliable -- especially when they're hidden inside another macro.
2140 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
2141 data/c.m4: Remove m4_divert(-1).
2142 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2143 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
2144 m4_divert_push(0) and m4_divert_pop(0).
2145 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
2146 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
2147 pushed and popped by m4sugar, should be first on the stack.
2149 Provide warn, complain, and fatal function callbacks to the skeletons.
2150 This provides more flexibility than m4_fatal, improves the error
2151 message format, and captures messages for translation. Discussed
2153 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
2154 * data/bison.m4 (b4_error): New, invoked by...
2155 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
2156 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
2157 directives. Because these M4 macros might be called when the current
2158 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
2159 the previous removal of uses of m4_divert, which caused trouble.
2160 (b4_check_percent_code_qualifiers): Use b4_complain instead of
2161 m4_fatal to report unrecognized %code qualifiers.
2162 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
2163 push parser requests.
2164 * data/glr.c: Use b4_complain instead of m4_fatal to report
2165 non-deterministic push parser requests.
2166 Update @output usage to @output(...@) form.
2167 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
2168 report missing %defines. Update @output usage to @output(...@) form.
2169 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
2171 * src/main.c (main): Invoke skel_scanner_free.
2172 * src/scan-skel.h (skel_scanner_free): Prototype new function.
2173 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
2174 obstack_for_string from flex-scanner.h.
2175 (YY_DECL): Use to declare skel_lex static.
2176 (decode_at_digraphs): Remove; now handled in the new
2177 SC_AT_DIRECTIVE_ARG start condition.
2178 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
2180 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
2181 at_directive_argv): New static globals.
2182 (INITIAL): Use fail_for_invalid_at.
2183 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
2184 recognize the start of a generalized `@directive(...@)' form and
2186 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
2187 directive args (using the new obstack_for_string), to decode the
2188 contained @ diagraphs, and to perform the directive. It recognizes
2189 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
2191 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
2192 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
2194 (scan_skel): Initialize obstack_for_string on the first call.
2195 (skel_scanner_free): New function to free obstack_for_string.
2196 * tests/input.at (Reject bad %code qualifiers): Update test output.
2198 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
2200 Consolidate the 4 prologue alternative directives (%code, %requires,
2201 %provides, and %code-top) into a single %code directive with an
2202 optional qualifier field. Discussed at
2203 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
2204 * NEWS (2.3a+): Rewrite the existing entry for the prologue
2206 * doc/bison.texinfo (Prologue Alternatives): Update.
2207 (Decl Summary): Update to %code "requires" and %code "provides".
2208 (Calc++ Parser): Update to %code "requires".
2209 (Table of Symbols): Remove entries for %requires, %provides, and
2210 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
2211 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
2212 are replaced by b4_percent_code_provides and b4_percent_code_requires,
2213 which are skeleton-specific.
2214 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
2215 declare what %code qualifiers it supports and to complain if any other
2216 qualifiers were used in the grammar.
2217 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
2218 and b4_user_code([b4_percent_code_provides]) in place of
2219 b4_user_requires and b4_user_provides.
2220 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
2221 Add b4_user_code([b4_percent_code_top]) and
2222 b4_user_code([b4_percent_code]).
2223 Invoke b4_check_percent_code_qualifiers.
2224 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2225 PERCENT_REQUIRES): Remove.
2226 (grammar_declaration): Remove RHS's for %code-top, %provides, and
2227 %requires. Rewrite the %code RHS as the unqualified form defining the
2228 muscle b4_percent_code. Add another RHS for the qualified %code form,
2229 which defines muscles of the form b4_percent_code_QUALIFIER and the
2230 b4_used_percent_code_qualifiers muscle.
2231 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2232 PERCENT_REQUIRES): Remove.
2233 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
2234 %code "requires" and %code "provides".
2235 * tests/input.at (Reject bad %code qualifiers): New.
2237 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2239 Use the new code_props interface for destructors and printers.
2240 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
2241 printer_location members, and change the type of the destructor and
2242 printer members to code_props.
2243 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
2244 symbol_printer_get, semantic_type_destructor_set,
2245 semantic_type_printer_set, default_tagged_destructor_set,
2246 default_tagless_destructor_set, default_tagged_printer_set,
2247 default_tagless_printer_set): Use code_props in arguments and return
2248 types in place of char const * and location.
2249 (symbol_destructor_location_get, symbol_printer_location_get): Remove
2250 since the locations are now contained in the return of
2251 symbol_destructor_get and symbol_printer_get.
2252 * src/output.c (symbol_destructors_output, symbol_printers_output):
2254 (symbol_code_props_output): ... this to eliminate duplicate code.
2255 (output_skeleton): Update to use symbol_code_props_output.
2256 * src/reader.c (symbol_should_be_used): Update use of
2257 symbol_destructor_get.
2258 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
2259 Update uses of the various _destructor_set and _printer_set functions.
2260 * src/symtab.c: (default_tagged_destructor_location,
2261 default_tagless_destructor_location, default_tagged_printer_location,
2262 default_tagless_printer_location): Remove since we...
2263 (default_tagged_destructor, default_tagless_destructor,
2264 default_tagged_printer, default_tagless_printer): ... change the type
2265 of these to code_props.
2266 (symbol_new, semantic_type_new, symbol_destructor_set,
2267 semantic_type_destructor_set, symbol_destructor_get,
2268 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
2269 symbol_check_alias_consistency, default_tagged_destructor_set,
2270 default_tagless_destructor_set, default_tagged_printer_set,
2271 default_tagless_printer_set): Update.
2272 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
2273 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
2275 (symbol_print): Use SYMBOL_CODE_PRINT.
2277 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2279 Use the new code_props interface for rule actions.
2280 * src/symlist.h (symbol_list): Replace action, action_location, and
2281 used members with a code_props action_props member.
2282 * src/reader.c (symbol_should_be_used, grammar_rule_check,
2283 grammar_midrule_action, grammar_current_rule_merge_set,
2284 grammar_current_rule_symbol_append, packgram): Update.
2285 * src/scan-code.h (translate_rule_action): Remove, no longer used.
2286 * src/scan-code.l (handle_action_dollar): Update.
2287 (translate_rule_action): Remove, no longer used.
2288 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
2290 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2292 Use the new code_props interface in parse-gram.y.
2293 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
2294 Update all uses of translate_* functions to use the new code_props
2295 interface and to use gram_scanner_last_string_free and
2296 code_scanner_last_string_free where possible.
2297 (grammar_declaration): symbol_list_destructor_set and
2298 symbol_list_printer_set now perform the translation, so don't do it
2299 here. Use gram_scanner_last_string_free where possible.
2300 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
2301 translate_code): Remove, no longer used.
2302 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
2303 symbol_list_printer_set): Perform code translation here rather than
2304 depending on the caller to do so.
2306 * src/symlist.h (struct symbol_list): Correct some documentation typos.
2307 * src/scan-gram.h (gram_last_string): Remove declaration.
2308 * src/scan-gram.l (last_string): Declare it static.
2310 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2312 Encapsulate code properties and related functionality for the various
2313 destructors, printers, and actions into a code_props structure and
2314 interface. This patch merely implements code_props in scan-code.h and
2315 scan-code.l. Future patches will rewrite other modules to use it.
2316 Discussed starting at
2317 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
2318 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
2319 consistently initialize const structs that have an empty location
2321 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
2322 to ensure consistency.
2323 * src/scan-code.h (code_props): New structure.
2324 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
2325 function, macro, and const global variable for initializing a
2326 code_props with no code.
2327 (code_props_plain_init, code_props_symbol_action_init,
2328 code_props_rule_action_init, code_props_translate_code): The rest of
2329 the new code_props functional interface. Among other things, the init
2330 functions set the code_props kind field so that
2331 code_props_translate_code will know whether to behave like
2332 translate_symbol_action, translate_rule_action, or translate_code.
2333 These old translate functions must remain until all other modules are
2334 updated to use the new code_props interface.
2335 (code_scanner_last_string_free): New function similar to
2336 gram_scanner_last_string_free.
2337 (code_scanner_free): Add documentation.
2338 * src/scan-code.l: Implement the new interface.
2339 (code_lex): Make it static, add a code_props* argument, and remove the
2341 (last_string): New static global similar to the one in scan-gram.l.
2342 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
2344 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
2345 code_props since Bison may one day use this information for destructors
2347 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
2348 (handle_action_dollar): Use symbol_list_n_get and set used flag
2349 directly since symbol_list_n_used_set is removed.
2350 (translate_action): Add a code_props* argument and remove the rule,
2351 action, and location arguments. Pass the code_props* on to code_lex.
2352 (translate_rule_action, translate_symbol_action, translate_code):
2353 Rewrite as wrappers around the new code_props interface.
2354 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
2355 it would eventually need to break the encapsulation of code_props.
2357 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
2359 * etc/.cvsignore: New.
2361 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
2363 Add maintainer-push-check to run maintainer-check using push parsing in
2364 place of pull parsing where available.
2365 * Makefile.am (maintainer-push-check): New.
2366 * data/bison.m4 (b4_use_push_for_pull_if): New.
2367 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
2368 appropriately based on their existing values.
2369 (yypush_parse): Don't print push-parser-specific diagnostics if push
2370 parsing is being used in place of pull parsing.
2371 * data/yacc.c: If push parsing should replace pull parsing, redirect to
2373 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
2374 variable, and insert b4_use_push_for_pull_flag into muscles.
2375 * tests/Makefile.am (maintainer-push-check): New.
2377 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2379 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
2380 (whether successful or failed) so that yypush_parse can be invoked
2381 again to start a new parse using the same yypstate.
2382 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
2383 check multiple yypull_parse invocations on the same yypstate. For pull
2384 mode, extend to check multiple yyparse invocations.
2385 (Exploding the Stack Size with Alloca): Extend to try with
2387 (Exploding the Stack Size with Malloc): Likewise.
2389 * tests/calc.at (Simple LALR Calculator): Don't specify
2390 %skeleton "push.c" since %push-pull-parser implies that now.
2391 * tests/headers.at (export YYLTYPE): Don't check for the push
2392 declarations. Otherwise, this test case can't be used to see if push
2393 mode can truly emulate pull mode.
2394 * tests/input.at (Torturing the Scanner): Likewise.
2395 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
2396 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
2397 AT_YACC_IF, which now includes the case of push mode since %skeleton
2398 need not be used for push mode. This will be more intuitive once
2399 push.c is renamed to yacc.c.
2401 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2403 For push mode, convert yyparse from a macro to a function, invoke yylex
2404 instead of passing a yylexp argument to yypull_parse, and don't
2405 generate yypull_parse or yyparse unless %push-pull-parser is declared.
2406 Discussed starting at
2407 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
2408 * data/bison.m4 (b4_pull_if): New.
2409 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
2410 * data/push.c: Improve M4 quoting a little.
2411 (b4_generate_macro_args, b4_parenthesize): Remove.
2412 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
2413 any time a pull parser is requested.
2414 Don't #define this as a wrapper around yypull_parse. Instead, when
2415 both push and pull are requested, make it a function that does that
2417 (yypull_parse): If there's a b4_prefix, #define this to
2418 b4_prefix[pull_parse] when both push and pull are requested.
2419 Don't define this as a function unless both push and pull are
2421 Remove the yylexp argument and hard-code yylex invocation instead.
2422 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
2424 * src/getargs.c (pull_parser): New global initialized to true.
2425 * getargs.h (pull_parser): extern it.
2426 * src/output.c (prepare): Insert pull_flag muscle.
2427 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
2428 (prologue_declaration): Set both push_parser and pull_parser = true for
2429 %push-pull-parser. Set push_parser = true and pull_parser = false for
2431 * src/scan-gram.l: Don't accept %push_parser as an alternative to
2432 %push-parser since there's no backward-compatibility concern here.
2433 Scan %push-pull-parser.
2434 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
2435 instead of %push-parser.
2436 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
2437 prototype it in the module that calls yyparse.
2438 * tests/input.at (Torturing the Scanner): Likewise.
2439 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
2441 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
2443 Update etc/bench.pl. Optimize push mode a little (the yyn change
2444 deserves most of the credit).
2445 * Makefile.am (SUBDIRS): Add etc subdirectory.
2446 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
2447 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
2448 yytoken, yyval, and yyloc declarations to...
2449 (yyparse or yypush_parse): ... here to improve performance. For
2450 yypush_parse invocations after the first, be sure to assign yyn its old
2452 (yypstate_new): Don't bother initializing the yyresult field since the
2453 initial value isn't used.
2454 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
2455 remove the #define that, in push mode, set it to yyps->NAME.
2456 * etc/Makefile.am: New.
2457 * etc/bench.pl: Remove and build it instead from...
2458 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
2459 "tests/bison" from the build directory by default rather than just
2460 invoking "bison" from $PATH.
2461 (calc_grammar): Update push parser code: don't declare yylval globally,
2462 don't define yyparse_wrapper, and don't #define yyparse.
2463 (bench_grammar): Update to check all working combinations of yacc.c,
2464 push.c, impure, pure, pull, and push.
2466 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2468 For push mode, add pull wrappers around yypush_parse.
2469 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
2470 (yypull_parse): New function wrapping yypush_parse.
2471 (yyparse): New #define wrapping yypull_parse.
2472 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
2474 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
2475 prototype yylex in the module that calls yyparse, and don't prototype
2476 yyparse there. Otherwise, the yyparse expansion won't compile.
2477 * tests/input.at (Torturing the Scanner): Likewise.
2479 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2481 Enable push parsers to operate in impure mode. Thus, %push-parser no
2482 longer implies %pure-parser. The point of this change is to move
2483 towards being able to test the push parser code by running the entire
2484 test suite as if %push-parser had been declared.
2485 * data/push.c (yypush_parse): For impure mode, remove the
2486 yypushed_char, yypushed_val, and yypushed_loc arguments.
2487 Instead, declare these as local variables initialized to the global
2488 yychar, yylval, and yylloc.
2489 For the first yypush_parse invocation only, restore the initial values
2490 of these global variables when it's time to read a token since they
2491 have been overwritten.
2492 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
2494 * tests/calc.at (Simple LALR(1) Calculator): Always declare
2495 %pure-parser along with %push-parser since this test case was designed
2496 for pure push parsers.
2497 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
2498 (AT_YACC_OR_PUSH_IF): New.
2499 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
2500 add a note that it's still wrong for some cases (as it has been for a
2502 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
2503 %push-parser no longer implies %pure-parser.
2505 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2507 Remove some unnecessary differences between the pull parser code and
2508 the push parser code. This patch enables yynerrs in push mode.
2509 * data/push.c: Reformat M4 a little.
2510 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
2511 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
2512 because push mode is on. Instead, if pure mode is on, move yynerrs
2514 (b4_declare_parser_state_variables): ... here.
2515 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
2516 to yyps->NAME so it can be used in yypush_parse.
2517 (yypush_parse): Don't omit uses of yynerrs in push mode.
2519 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2521 Fix bug such that the first pushed token's value and location are
2522 sometimes overwritten (sometimes by %initial-action) before being used.
2523 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
2524 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
2525 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
2526 more closely mimic the pull parser logic.
2527 Don't copy the pushed token to yychar, yylval, and yylloc until it's
2528 time to read a token, which is after any initialization of yylval and
2530 (gottoken): Rename label to...
2531 (yyread_pushed_token): ... for clarity and to avoid infringing on the
2534 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2536 Rearrange initialization of the parser state variables so that the
2537 skeleton doesn't have to have a copy for pull mode and another for push
2538 mode. This patch also fixes at least a bug such that yylloc was not
2539 initialized (with b4_location_initial_line and
2540 b4_location_initial_column) upon calling yypush_parse. However, that
2541 initialization now overwrites the first token's location;
2542 %initial-action assigning @$ already did the same thing, and both bugs
2543 will be fixed in a later patch.
2544 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
2545 (b4_declare_parser_state_variables): Remove initialization of yytoken,
2546 yyss, yyvs, yyls, and yystacksize.
2547 (yypstate_new): Remove initialization of some yypstate fields: yystate,
2548 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
2550 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
2551 yyps->NAME so it can be used in yypush_parse.
2552 (yyparse or yypush_parse): For yypush_parse, don't print the
2553 "Starting parse" diagnostic for invocations after the first.
2554 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
2555 yypush_parse, only do it for the first invocation.
2556 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
2557 initialization to occur in yypush_parse but only on the first
2560 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2562 * data/push.c: Add CPP guards around push parser declarations in both
2563 the header and the code file.
2564 In the code file, move the push parser declarations to the same place
2565 they appear in the header file.
2566 Clean up the M4 some, especially the inconsistent underquoting in
2567 some b4_c_function_def and b4_c_function_decl uses.
2569 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2571 Encapsulate the push parser state variables into an M4 macro so the
2572 push skeleton doesn't have to list them again for pull mode's yyparse.
2573 For push mode, remove yypush_parse's local equivalents of these
2574 variables to eliminate unnecessary copying between the two sets at
2575 run-time. This patch also fixes at least a bug related to multiple
2576 %initial-action invocations in push mode.
2577 * data/push.c (b4_declare_parser_variables): Rename to...
2578 (b4_declare_scanner_communication_variables): ... this for clarity and
2580 (b4_declare_yyparse_variables): Remove and move its contents to the one
2581 spot where it was invoked.
2582 (b4_declare_parser_state_variables): New macro containing the parser
2583 state variables required by push mode.
2584 (struct yypstate): Replace all fields but yynew with
2585 b4_declare_parser_state_variables.
2586 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
2587 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
2588 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
2589 (yyparse or yypush_parse): For yyparse in pull mode, replace local
2590 parser state variable declarations with
2591 b4_declare_parser_state_variables.
2592 Don't initialize parser state variables when calling yypush_parse since
2593 yypstate_new already does that.
2594 Invoke the user's initial action only upon the first yypush_parse
2596 Remove all code that copies between the local parser state variables
2599 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2601 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
2602 prevent a name collision in a future patch where these names will
2603 sometimes be #define'd.
2604 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
2605 since it no longer has the same name as the existing argument.
2606 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
2608 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
2609 and Joel E. Denny <jdenny@ces.clemson.edu>
2611 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
2612 that the argument is case-insensitive, and there's no `=' here.
2613 For the %skeleton entry, mention that %language is better.
2614 (Bison Options): Likewise for --language and --skeleton. Move the
2615 --skeleton entry so that the `Tuning the parser' section is sorted
2616 alphabetically on long options.
2617 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
2618 %language directive in detail here; cross-reference the %language
2619 documentation instead.
2620 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
2621 `%require "2.3b"' so that the example is always up-to-date.
2622 (Table of Symbols): Add entries for %language and %skeleton.
2623 * examples/extexi (normalize): Instead of replacing every %require
2624 argument with the current Bison version, just substitute for
2625 `@value{VERSION}'. This guarantees that we're testing what actually
2626 appears in the documentation.
2627 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
2628 rather than `@VERSION@'.
2630 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2632 * NEWS: Reword the %language news a bit, and put it earlier.
2634 * src/getargs.c (skeleton_arg): Last arg is now location const *.
2635 Rewrite to simplify the logic.
2636 (language_argmatch): Likewise.
2637 (program_name): We now own this var.
2638 * src/getargs.h (struct bison_language): Use char[] rather than
2641 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
2643 * src/complain.c (program_name): Remove decl; no longer needed.
2644 * src/main.c (program_name): Remove; now belongs to getargs.
2646 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
2648 * NEWS: Document %language.
2650 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
2652 * data/c-skel.m4, data/c++-skel.m4: New files.
2653 * data/glr.c: Complain on push parsers.
2655 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
2657 (Decl Summary): Document %language and %skeleton.
2658 (Command line): Document -L.
2660 * examples/extexi: Rewrite %require directive.
2661 * examples/calc++/Makefile.am: Pass VERSION to extexi.
2663 * src/files.c (compute_exts_from_gc): Look in language structure
2665 (compute_file_name_parts): Check whether .tab should be added.
2666 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
2667 (language, skeleton_arg, language_argmatch): New.
2668 (long_options): Add --language.
2669 (getargs): Use skeleton_arg, add -L/--language.
2670 * src/getargs.h: Include location.h.
2671 (struct bison_language, language, skeleton_arg, language_argmatch): New.
2672 * src/output.c (prepare): Pick default skeleton from struct language.
2673 Don't dispatch C skeletons here.
2674 * src/parse-gram.y (PERCENT_LANGUAGE): New.
2675 (prologue_declaration): Add "%language" rule, use skeleton_arg.
2676 * src/scan-gram.l ("%language"): New rule.
2678 * tests/calc.at: Test %skeleton and %language.
2679 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
2680 (AT_GLR_IF): Look for %skeleton "glr.cc".
2681 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
2682 (AT_YACC_IF): Reject %language.
2684 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2686 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
2687 since it wasn't used; only the typedef name 'semantic_type' is needed.
2688 Also, omit trailing white space.
2690 * bootstrap: Sync from coreutils.
2691 (gnulib_extra_files): Add build-aux/announce.gen.
2692 (slurp): Adjust .gitignore files like .cvsignore files.
2693 * build-aux/announce-gen: Remove from CVS, since bootstrap
2696 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
2698 Make %push-parser imply %pure-parser. This fixes several bugs; see
2699 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
2700 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
2702 * data/push.c: Don't bother testing b4_push_if when deciding whether
2703 to expand b4_declare_parser_variables globally.
2704 (yypush_parse): Likewise in here.
2706 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
2707 (yy_reduce_print): Reformat M4 for readability.
2709 2006-12-15 Bob Rossi <bob@brasko.net>
2710 and Joel Denny <jdenny@ces.clemson.edu>
2712 * data/push.c (yypstate): Add typedef, and update all uses of
2713 struct yypstate to just yypstate.
2714 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
2716 2006-12-14 Bob Rossi <bob@brasko.net>
2718 * data/push.c (yypush_parse): Declare prototype regardless of
2721 2006-12-14 Bob Rossi <bob@brasko.net>
2723 * data/push.c (yyparse): Remove the prototype and the #define when in
2726 2006-12-13 Bob Rossi <bob@brasko.net>
2728 * data/push.c (yypstate_init): Rename to...
2729 (yypstate_new): ... this and use b4_c_function_def.
2730 (yypstate_delete): New.
2731 (yypush_parse): Change parameters yynval and yynlloc to be const.
2732 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
2733 yypstate_delete functions.
2735 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
2737 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
2738 strange test case titles. Reported by Bob Rossi.
2740 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
2742 * TODO: Add pointer to Sylvain Schmitz's work on static detection
2743 of potential ambiguities in GLR grammers.
2745 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
2747 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
2748 `bison ', use m4_index instead of m4_substr since chopping up a string
2749 containing M4-special characters causes problems here.
2751 Fix a couple of bugs related to special characters in user-specified
2752 file names, and make it easier for skeletons to compute output file
2753 names with the same file name prefix as Bison-computed output file
2755 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
2756 b4_parser_file_name and b4_spec_defines_file instead of
2757 @output_parser_name@ and @output_header_name@, which are now redundant.
2758 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
2759 b4_parser_file_name, b4_spec_defines_file, and the new
2760 @basename(FILENAME@) instead of @output_parser_name@ and
2761 @output_header_name@, which inappropriately escaped the file names as
2763 * src/files.c (all_but_ext): Remove static qualifier.
2764 (compute_output_file_names): Move `free (all_but_ext)' to...
2765 (output_file_names_free): ... here since all_but_ext is needed later.
2766 * src/files.h (all_but_ext): Extern.
2767 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
2768 exactly what MUSCLE_INSERT_STRING used to do.
2769 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
2770 characters are escaped properly.
2771 * src/output.c (prepare): Define muscle file_name_all_but_ext as
2773 For pkgdatadir muscle, maintain previous functionality by using
2774 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
2775 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
2776 digraphs would never be expanded. Hopefully no one has M4-special
2777 characters in his Bison installation path.
2778 * src/scan-skel.l: Don't parse @output_header_name@ and
2779 @output_parser_name@ anymore since they're now redundant.
2780 In @output, use decode_at_digraphs.
2781 Parse a new @basename command that invokes last_component.
2782 (decode_at_digraphs): New.
2783 (BASE_QPUTS): Remove unused.
2784 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
2785 (Output file name): New tests.
2787 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
2789 Warn about output files that are generated by the skeletons and that
2790 conflict with other output files.
2791 * data/glr.c: Don't generate the header file here when glr.cc does.
2792 * src/files.c (file_names, file_names_count): New static globals.
2793 (compute_output_file_names): Invoke output_file_name_check for files
2794 not generated by the skeletons and remove existing checks.
2795 (output_file_name_check): New function that warns about conflicting
2797 (output_file_names_free): Free file_names.
2798 * src/files.h (output_file_name_check): Declare.
2799 * src/scan-skel.l: Invoke output_file_name_check for files generated by
2801 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
2802 (Conflicting output files): New tests.
2804 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2806 * doc/bison.texinfo: Fix a couple of typos.
2808 2006-12-08 Bob Rossi <bob@brasko.net>
2810 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
2812 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
2814 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
2815 (yypush_parse): Rename yypvars argument to yyps and remove redundant
2817 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
2818 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
2820 2006-12-07 Bob Rossi <bob@brasko.net>
2821 and Joel Denny <jdenny@ces.clemson.edu>
2823 * data/push.c (yypvarsinit): Change return type from void* to struct
2824 yypvars*. No longer cast to void* on return.
2825 (struct yypvars): Remove yylen since it need not be remembered between
2826 yypushparse invocations.
2827 (yypushparse): Don't copy between yylen and pv->yylen.
2829 2006-12-05 Bob Rossi <bob@brasko.net>
2831 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
2832 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
2833 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
2834 (struct yypvars): Remove b4_declare_parser_variables.
2835 (yypvarsinit): Remove init code for removed variables.
2836 (global scope): Do not declare b4_declare_parser_variables if
2838 (yypushparse): Add b4_declare_parser_variables.
2839 Init new local variables, and remove init code for removed
2842 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
2843 and yyparse for other modes.
2844 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
2845 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
2846 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
2847 (AT_PURE_LEX_IF): True if pure or push parser.
2849 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
2851 Document Yacc prologue alternatives and default %destructor's and
2852 %printer's as experimental. Don't mention Java yet. Discussed at
2853 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.

2876 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
2877 occurrence of each of %file-prefix and %output. Add check for %defines
2879 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
2880 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
2881 Remove the `=' from %output.
2883 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
2885 Don't escape $ in test case titles since Autoconf 2.61 now does that
2887 * tests/actions.at (Default %printer and %destructor are not for error
2888 or $undefined): Here.
2889 (Default %printer and %destructor are not for $accept): Here.

2892 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
2894 Rename <!> to <>. Discussed starting at

2904 * tests/actions.at (Default tagless %printer and %destructor,
2905 Default tagged and per-type %printer and %destructor,
2906 Default %printer and %destructor are not for error or $undefined,
2907 Default %printer and %destructor are not for $accept,
2908 Default %printer and %destructor for mid-rule values): Update.
2909 * tests/input.at (Default %printer and %destructor redeclared,
2910 Unused values with default %destructor): Update.

2925 grammar is maintained with Bison's highest standards.
2926 * src/getargs.c: Fix some typos in Doxygen comments.
2928 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
2930 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
2931 later. Reported by Paul Eggert in
2932 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
2933 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
2934 * src/scan-code.l (translate_action): Don't bother invoking
2935 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
2936 (code_scanner_free): Instead of invoking
2937 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

2945 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
2946 has been called previously for the same key.
2947 (muscle_find): Return storage instead of value so that
2948 --enable-gcc-warnings doesn't produce warnings that the return discards
2949 const. aver that the value and storage are the same since storage
2950 could potentially be NULL when value is not.
2951 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
2954 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2956 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
2957 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives

2959 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
2962 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
2963 and Paul Eggert <eggert@cs.ucla.edu>

2968 since they are freed.
2969 * src/files.c: Likewise.
2970 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
2972 (tr): Now operates in-place. All uses changed.

2975 (compute_file_name_parts, compute_output_file_names): Don't store
2976 read-only data in variables that will be freed.
2977 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
2978 src_extension, and header_extension.
2979 (output_file_names_free): New public function to free
2980 spec_verbose_file, spec_graph_file, spec_defines_file,
2981 parser_file_name, and dir_prefix.
2982 * src/getargs.c (getargs): Don't store read-only data in variables that
2984 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
2985 (which previously existed but was unused), and quotearg_free.
2986 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
2987 * src/muscle_tab.c: Likewise.
2988 (muscle_entry): Make the value char const *,
2989 and add a new storage member that is char * and can be freed.
2990 (muscle_entry_free): New private function.
2991 (muscle_init): Use it instead of free.
2992 (muscle_insert, muscle_grow): Update and use new storage member.
2993 (muscle_code_grow): Free the string passed to muscle_grow
2994 since it's not needed anymore.
2995 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
2996 add a new `char *code' member.
2997 ("{...}"): Declare semantic type as code.
2998 * src/scan-code.h (translate_rule_action):
2999 (translate_symbol_action, translate_code, translate_action): Return
3000 `char const *' rather than `char *' since external code should not free
3002 * src/scan-code.l: Likewise.
3003 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
3004 which is "{...}" in the parser.
3005 * tests/Makefile.am (maintainer-check-valgrind): Set
3006 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
3008 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
3010 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
3011 expecting a non-zero exit status sets --leak-check=summary and
3012 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
3013 this case, and we don't want to hear about it.
3015 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3017 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
3018 instead of from the template, to simplify configuration a bit.

3034 declarations): Run tests with and without --warnings=midrule-values.
3036 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
3037 than LIST_FREE directly.

3058 empty subargument list. For example: `bison --warnings= parser.y'.
3060 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3062 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
3063 the parser header file so that gcc doesn't warn.
3065 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3067 Split the default %destructor/%printer into two kinds: <*> and <!>.

3115 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
3116 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
3117 like $@n instead of just @n so that the default %destructor/%printer
3118 logic doesn't see them as user-defined symbols.
3119 (symbol_is_dummy): Check for both forms of the name.
3120 * src/reader.c (packgram): Remove the `$' from each midrule symbol
3121 name for which the midrule value is referenced in any action.

3132 (packgram): Before invoking grammar_rule_check on any rule, make sure
3133 all actions have already been scanned in order to set `used' flags.
3134 Otherwise, checking that a midrule's $$ is set will not always work
3135 properly because the midrule check must forward-reference the midrule's
3137 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
3140 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
3142 More improvements to the documentation of the prologue alternatives:
3143 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
3145 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
3146 some text to clarify the relative importance of the new directives and
3147 to show how these directives may be viewed as code labels.
3149 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
3151 Similar to the recently removed %before-header, add %code-top as the
3152 alternative to the pre-prologue. Mentioned at
3153 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
3154 Also, let the prologue alternatives appear in the grammar section.
3155 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
3156 (prologue_declaration): Move the existing prologue alternatives to...
3157 (grammar_declaration): ... here and add %code-top.

3207 Work also when the working directory (with e.g. coreutils sources)
3208 is version controlled with git, rather than CVS.
3209 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
3211 In messages and comments, say e.g., "checked-out sources",
3212 rather than "CVS sources".
3213 (version_controlled_file): New function. Work for git as well as
3214 for CVS. Don't use grep's -q option.
3215 (slurp): Call it here, in place of CVS-specific code.
3217 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
3219 Fix testsuite for ./configure --enable-gcc-warnings:
3220 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
3221 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
3222 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
3223 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.

3262 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3264 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
3265 variable was sometimes used without being initialized. This
3266 messed up the installation of the INSTALL file in some cases.
3268 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
3270 * bootstrap (usage, main program, symlink_to_gnulib): Add option
3271 --copy. Inspired by a suggestion from Bruno Haible.
3273 2006-10-03 Jim Meyering <jim@meyering.net>
3275 * bootstrap: Undo last change to this file, since now gnulib-tool
3276 sticks with the automake default in generating dependencies.
3278 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3280 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
3281 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
3283 * doc/bison.1: Add copyright notice.

3304 * src/print_graph.c: Include graphviz.h rather than vcg.h.
3305 (static_graph, fgraph): Remove. All uses changed to pass
3306 arguments instead of sharing a static var.
3307 (print_core, print_actions, print_state, print_graph):
3308 Output graphviz format rather than VCG format.
3309 * tests/.cvsignore: Remove *.vcg; add *.dot.
3310 * tests/output.at: Expect *.dot files, not *.vcg files.
3312 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
3313 accommodates the 2006-10-08 change.
3315 2006-10-11 Bob Rossi <bob@brasko.net>
3317 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.

3319 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
3320 (yypvarsinit): Remove init of removed fields.
3321 (yypushparse): Remove use of removed fields; use new macros instead.
3323 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3325 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
3326 in a push parser. Reindent slightly to match yacc.c better.
3328 2006-10-11 Bob Rossi <bob@brasko.net>
3330 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
3332 (yypvarsinit, yypushparse): Remove init of removed fields.

3342 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
3343 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
3344 b4_define_user_cde and uses): Remove.
3345 (b4_comment, b4_prefix, b4_sync_start): New.
3346 * data/bison.m4: New file, with most of the content removed from c.m4.
3347 * src/muscle_tab.h: Use "do {...} while(0)" throughout.

3354 Fix test failure reported by Tom Lane in
3355 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
3356 and try to make such failures easier to catch in the future.
3357 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
3358 that's now the caller's responsibility.
3359 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
3360 Set yychar = YYEOF if it's negative.
3361 * tests/actions.at (yylex): Abort if asked to read past EOF.

3371 Fix problems with translating English-language diagnostics.
3372 * bootstrap: Fix bug introduced in recent bootstrap changes, with
3373 respect to bison-runtime pot generation. The YY_ stuff
3374 wasn't being captured.
3375 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
3376 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
3377 * runtime-po/POTFILES.in: Add data/push.c.
3379 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
3381 Merge bootstrap changes from coreutils.
3383 2006-09-28 Jim Meyering <jim@meyering.net>
3385 Automatically generated dependencies are important even
3386 when all of the sources in a directory come from gnulib.
3387 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
3388 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
3390 2006-09-23 Jim Meyering <jim@meyering.net>
3392 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
3394 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>

3409 (YYPUSH_MORE): Add #define.
3410 (yypushparse): Modify return value.
3412 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
3414 * stamp-h.in: Remove; no longer needed.
3415 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
3416 Remove config.h, config.hin, intl (no longer created).
3417 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
3420 Sync bootstrap from coreutils, as follows:
3422 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
3424 * bootstrap (symlink_to_gnulib): New function.
3425 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
3426 to copies-of-gnulib.
3427 (cp_mark_as_generated, slurp, gnulib_files):
3428 Avoid making a copy if it's the same as the old version.
3429 (gnulib_files): Add support for this variable (used by Bison).
3431 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
3433 * src/getargs.c (usage): Rework to use conventions similar to
3434 coreutils, to make translation a bit easier and the code a bit
3435 smaller. Problem reported by Tim Van Holder.
3437 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
3439 Use some of gnulib's new modules, taken from coreutils.
3441 * bootstrap: Sync from coreutils, except add support for gnulib_files.
3442 * bootstrap.conf: New file.
3443 (gnulib_modules): Add configmake, inttypes, unistd.
3444 (XGETTEXT_OPTIONS): Add complain, complain_at,
3445 fatal, fatal_at, warn, warn_at, unexpected_end.
3446 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
3447 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
3449 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
3451 (GNULIB_AUTOCONF_SNIPPET): Remove.
3452 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
3454 * lib/.cvsignore: Add inttypes_.h.
3455 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
3456 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
3457 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
3458 no-longer-necessary initializations.
3459 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
3460 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
3461 use the unistd module.
3462 * src/system.h: Likewise.
3463 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
3464 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
3465 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
3466 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
3467 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
3468 * src/system.h: Include inttypes.h unconditionally, now that we
3469 use the inttypes module. Don't bother to include stdint.h, since
3470 inttypes.h now does that for us.
3471 (LOCALEDIR): Remove, now that we use the configmake module.
3472 * src/getargs.c: Include configmake.h.
3473 * src/main.c: Likewise.
3474 * src/output.c: Likewise.
3475 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
3476 not from $abs_top_builddir, since config.h moved.
3479 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
3480 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
3482 * src/parse-gram.y (symbol_declaration): Don't put statements
3483 before declarations; it's not portable to C89.
3484 * src/scan-code.l (handle_action_at): Likewise.
3486 * src/scan-code.l: Always initialize braces_level; the old code
3487 left it uninitialized and therefore had undefined behavior.
3489 Don't attempt to redefine 'assert', since it runs afoul of
3490 systems where standard headers (mistakenly) include <assert.h>.
3491 Instead, define and use our own alternative, called 'aver'.
3492 * src/reader.c: Don't include assert.h, since we no longer
3494 * src/scan-code.l: Likewise.
3495 * src/system.h (assert): Remove, replacing with....
3496 (aver): New function, taking a bool arg. All uses changed.
3497 * src/tables.c (pack_vector): Ensure that aver arg is bool,
3498 not merely an integer.
3500 2006-09-15 Bob Rossi <bob@brasko.net>
3502 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
3503 * data/c.m4 (YYPUSH): New.
3504 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
3505 * src/getargs.c (push_parser): New var.
3506 * src/getargs.h (push_parser): New declaration.
3507 * src/output.c (prepare): Add macro insertion of `push_flag'.
3508 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
3509 (prologue_declaration): Parse %push-parser.
3510 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
3511 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
3512 list of removed lines from the traces observed.
3513 (AT_CHECK_CALC_LALR): Added push parser tests.
3515 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
3517 * NEWS: Version 2.3a.
3518 * configure.ac (AC_INIT): Likewise.
3520 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
3521 "#define YYSTYPE int" that caused "make maintainer-check" to fail
3522 due to header ordering dependencies. I don't know why the #define
3525 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
3526 runtime cost when YYDEBUG is not defined, and so that some tests
3527 that used to fail now work. Problem and initial suggestion by
3529 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
3530 * data/glr.cc (b4_parser_class_name):
3531 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
3532 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
3533 (yydebug_) [YYDEBUG]: New member.
3534 (yycdebug_): Now defined only if YYDEBUG.
3535 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
3536 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
3537 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
3539 (debug_stream, set_debug_stream, debug_level, set_debug_level):
3540 Define only if YYDEBUG.
3541 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
3543 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
3544 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
3545 AT_CHECK_CALC_GLR_CC that are working now.
3547 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
3549 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
3550 We don't need them in glr.cc, and glr.c defines them.
3551 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
3552 assumes that defining it to anything is the same as defining
3553 it to 1. Problem reported by Paolo Bonzini.
3555 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
3557 * data/c.m4 (b4_null, b4_case): Define.
3558 * src/output.c (prepare_symbols): Use b4_null.
3559 (user_actions_output): Use b4_case.
3561 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
3563 * data/glr.c (b4_shared_declarations): Put start-header first,
3564 before any #includes that we generate, so that feature-test
3565 macros work. Problem reported by Michael Deutschmann in
3566 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
3567 * data/lalr1.cc: Likewise.
3568 * doc/bison.texinfo (Prologue): Document that feature-test macros
3569 should be defined before any Bison declarations.
3570 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
3571 that depend on location.hh after, not before, Bison decls, since
3572 we now include location.hh after the first user prologue.
3574 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
3575 Sander Brandenburg in
3576 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
3577 Also, fix minor white space and comment issues.
3578 (Prologue): Mention that it's better to define feature-test macros
3579 before Bison declarations. Problem reported by Michael Deutschmann.
3581 * README-cvs: Fix typo: "&" should be "&&". Problem reported
3583 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
3584 This adjusts to recent gnulib changes.
3586 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3588 Finish implementation of per-type %destructor/%printer. Discussed
3590 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
3592 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
3593 * NEWS (2.3+): Add a description of this feature to the default
3594 %destructor/%printer description.
3595 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
3596 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3597 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
3598 list node contains a semantic type.
3599 * src/symtab.c, src/symtab.h: Extend with a table that associates
3600 semantic types with their %destructor's and %printer's.
3601 (semantic_type_from_uniqstr, semantic_type_get,
3602 semantic_type_destructor_set, semantic_type_printer_set): New functions
3603 composing the public interface of that table.
3604 (symbol_destructor_get, symbol_destructor_location_get,
3605 symbol_printer_get, symbol_printer_location_get): If there's no
3606 per-symbol %destructor/%printer, look up the per-type before trying
3608 * tests/actions.at (Per-type %printer and %destructor): New test case.
3609 * tests/input.at (Default %printer and %destructor redeclared):
3610 Extend to check that multiple occurrences of %symbol-default in a
3611 single %destructor/%printer declaration is an error.
3612 (Per-type %printer and %destructor redeclared, Unused values with
3613 per-type %destructor): New test cases.
3615 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3617 Require default %destructor/%printer to be declared using
3618 %symbol-default instead of an empty symbol list, and start working on
3619 new per-type %destructor/%printer. Discussed at
3620 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
3621 * NEWS (2.3+): Add %symbol-default to example.
3622 * bison.texinfo (Freeing Discarded Symbols): Likewise.
3623 (Table of Symbols): Add entry for %symbol-default.
3624 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
3625 (generic_symlist, generic_symlist_item): New nonterminals for creating
3626 a list in which each item is a symbol, semantic type, or
3628 (grammar_declaration): Use generic_symlist in %destructor and %printer
3629 declarations instead of symbols.1 or an empty list.
3630 (symbol_declaration, precedence_declaration, symbols.1): Update actions
3631 for changes to symbol_list.
3632 * src/reader.c: Update for changes to symbol_list.
3633 * src/scan-code.l: Likewise.
3634 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
3635 * src/symlist.c, src/symlist.h: Extend such that a list node may
3636 represent a semantic type or a %symbol-default in addition to just an
3637 ordinary symbol. Add switched functions for setting %destructor's and
3639 * tests/actions.at, tests/input.at: Add %symbol-default to all default
3640 %destructor/%printer declarations.
3642 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
3644 Whether the default %destructor/%printer applies to a particular symbol
3645 isn't a question of whether the user *declares* that symbol (in %token,
3646 for example). It's a question of whether the user by any means
3647 *defines* the symbol at all (by simply using a char token, for
3648 example). $end is defined by Bison whereas any other token with token
3649 number 0 is defined by the user. The error token is always defined by
3650 Bison regardless of whether the user declares it with %token, but we
3651 may one day let the user define error as a nonterminal instead.
3652 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
3653 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
3654 the meaning of "user-defined".
3655 * tests/actions.at (Default %printer and %destructor for user-declared
3656 end token): Rename to...
3657 (Default %printer and %destructor for user-defined end token): ...
3660 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
3661 computation of whether to apply the default, don't maintain a list of
3662 every Bison-defined symbol. Instead, just check for a first character
3663 of '$', which a user symbol cannot have, and check for the error token.
3665 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
3667 Don't apply the default %destructor or %printer to the error token,
3668 $undefined, or $accept. This change fits the general rule that the
3669 default %destructor and %printer are only for user-declared symbols,
3670 and it solves several difficulties that are described in the new test
3672 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
3673 * tests/actions.at (Default %printer and %destructor are not for error
3674 or $undefined, Default %printer and %destructor are not for $accept):
3677 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
3679 Allow %start after the first rule.
3680 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
3681 when parsing the first rule.
3682 (check_and_convert_grammar): Search for it here after all grammar
3683 declarations have been parsed. Skip midrules, which have dummy LHS
3685 * src/symtab.c (symbol_is_dummy): New function.
3686 * src/symtab.h (symbol_is_dummy): Declare it.
3687 * tests/input.at (%start after first rule): New test.
3689 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3691 Redo some of the previous commit: add back the ability to use
3692 non-aliased/undeclared string literals since it might be useful to
3693 those declaring %token-table.
3694 * src/reader.c (check_and_convert_grammar): Undo changes in previous
3695 commit: don't worry about complaints from symbols_pack.
3696 * src/symtab.c (symbol_new, symbol_class_set,
3697 symbol_check_alias_consistency): Undo changes in previous commit: count
3698 each string literal as a new symbol and token, assign it a symbol
3699 number, and don't complain about non-aliased string literals.
3700 (symbols_pack): Since symbol_make_alias still does not decrement symbol
3701 and token counts but does still set aliased tokens to the same number,
3702 symbol_pack_processor now leaves empty slots in the symbols array.
3704 * tests/regression.at (Undeclared string literal): Remove test case
3705 added in previous commit since non-aliased string literals are allowed
3707 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
3708 remove unnecessary string literal declarations.
3709 * tests/sets.at (Firsts): Likewise.
3711 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3713 Don't allow an undeclared string literal, but allow a string literal to
3714 be used before its declaration.
3715 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
3716 symbols_pack complained.
3717 * src/symtab.c (symbol_new): Don't count a string literal as a new
3719 (symbol_class_set): Don't count a string literal as a new token, and
3720 don't assign it a symbol number since symbol_make_alias does that.
3721 (symbol_make_alias): It's not necessary to decrement the symbol and
3722 token counts anymore. Don't assume that an alias declaration occurs
3723 before any uses of the identifier or string, and thus don't assert that
3724 one of them has the highest symbol number so far.
3725 (symbol_check_alias_consistency): Complain if there's a string literal
3726 that wasn't declared as an alias.
3727 (symbols_pack): Bail if symbol_check_alias_consistency failed since
3728 symbol_pack asserts that every token has been assigned a symbol number
3729 although undeclared string literals have not.
3730 * tests/regression.at (String alias declared after use, Undeclared
3731 string literal): New test cases.
3732 (Characters Escapes, Web2c Actions): Declare string literals as
3734 * tests/sets.at (Firsts): Likewise.
3736 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
3738 In the grammar scanner, STRING_FINISH unclosed constructs and return
3739 them to the parser in order to improve error messages.
3740 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
3741 SC_BRACED_CODE, SC_PROLOGUE): Implement.
3742 * tests/input.at (Unclosed constructs): New test case.
3743 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
3746 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
3749 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
3751 Handle string aliases for character tokens correctly.
3752 * src/symtab.c (symbol_user_token_number_set): If the token has an
3753 alias, check and set its alias's user token number instead of its own,
3754 which is set to indicate the alias. Previously, every occurrence of
3755 the character token in the grammar overwrote that alias indicator with
3757 * tests/input.at (String aliases for character tokens): New test.
3759 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
3761 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
3763 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
3765 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
3766 to prevent failures when building on older platforms.
3767 Check for autopoint failure.
3768 Set XGETTEXT_OPTIONS to values that check for C format strings,
3769 so that translators are warned about them (this also helps
3770 prevent core dumps).
3772 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
3773 function, since it simplifies our code a bit.
3775 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
3776 rather than -W, so we don't get bogus warnings about sign comparisons.
3777 Add -Wpointer-arith, since that warning is useful (it reports code
3778 that does not conform to C89 and that some compilers reject).
3779 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
3780 since it's no longer needed.
3782 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
3784 Clean up scanners a bit.
3785 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
3786 definitions so gcc won't warn when obstack_for_string is unused.
3787 * src/scan-code.l: config.h and system.h are already #include'd by
3788 scan-code-c.c, so get rid of them here.
3789 * src/scan-gram.l: Likewise.
3790 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
3791 definitions rather than duplicating the rest of it.
3792 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
3794 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
3796 Suppress signed/unsigned comparison warnings for yycheck.
3797 * data/c.m4 (b4_safest_int_type): New macro.
3798 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
3799 a signed int type, cast it to b4_safest_int_type first.
3800 * data/yacc.c: Likewise.
3801 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
3804 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
3806 * doc/bison.texinfo: Fix some typos.
3808 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
3810 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
3811 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
3813 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
3814 the latest gnulib does this a different way.
3815 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
3816 translation was patched, so stop omitting it.
3818 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3820 Enable declaration of default %printer/%destructor. Make the parser
3821 use these for all user-declared grammar symbols for which the user does
3822 not declare a specific %printer/%destructor. Thus, the parser uses it
3823 for token 0 if the user declares it but not if Bison generates it as
3824 $end. Discussed starting at
3825 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
3826 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
3828 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
3829 * NEWS (2.3+): Mention.
3830 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
3831 declare a %destructor for a mid-rule's semantic value. It's just
3832 impossible to declare one specific to it.
3833 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
3834 code. Describe default %destructor form.
3835 * src/parse-gram.y (grammar_declaration): Parse default
3836 %printer/%destructor declarations.
3837 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
3838 and symbol_destructor_location_get rather than accessing the destructor
3839 and destructor_location members of struct symbol.
3840 (symbol_printers_output): Likewise but for %printer's.
3841 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
3843 * src/symtab.c (default_destructor, default_destructor_location,
3844 default_printer, default_printer_location): New static global
3845 variables to record the default %destructor and %printer.
3846 (symbol_destructor_get, symbol_destructor_location_get,
3847 symbol_printer_get, symbol_printer_location_get): New functions to
3848 compute the appropriate %destructor and %printer for a symbol.
3849 (default_destructor_set, default_printer_set): New functions to set the
3850 default %destructor and %printer.
3851 * src/symtab.h: Prototype all those new functions.
3852 * tests/actions.at (Default %printer and %destructor): New test to
3853 check that the right %printer and %destructor are called, that they're
3854 not called for $end, and that $$ and @$ work correctly.
3855 (Default %printer and %destructor for user-declared end token): New
3856 test to check that the default %printer and %destructor are called for
3857 a user-declared end token.
3858 * tests/input.at (Default %printer and %destructor redeclared, Unused
3859 values with default %destructor): New tests to check related grammar
3860 warnings and errors.
3862 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3864 Clean up handling of %destructor for the end token (token 0).
3865 Discussed starting at
3866 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
3868 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
3870 Make the skeletons consistent in how they pop the end token and invoke
3872 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
3873 state, which has token number 0, since this would invoke the
3874 %destructor for the end token.
3875 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
3876 until after shifting the end token, or else it won't be popped.
3877 * data/yacc.c (yyparse): Likewise.
3879 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
3880 it's the end token. Upon termination, destroy an unshifted lookahead
3881 even when it's the end token.
3882 * data/lalr1.cc (yy::parser::parse): Likewise.
3883 * data/yacc.c (yyparse): Likewise.
3885 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
3886 value warnings for the end token when the user gives the end token a
3889 * tests/actions.at (Printers and Destructors): Test all the above.
3891 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
3893 Update to latest gnulib and gettext versions.
3894 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
3896 (gnulib_files): Add m4/warning.m4. Don't worry about files
3897 overwritten by autopoint.
3898 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
3899 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
3901 Don't use autoreconf; instead, invoke autopoint etc. by hand,
3902 so that we can remove the intl files at a better time.
3903 (intl_files_to_remove): Remove aclocal.m4, since it gets
3904 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
3905 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
3906 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
3907 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
3908 Remove datarootdir hack; no longer needed.
3909 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
3910 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
3911 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
3913 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
3914 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
3916 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3918 * bootstrap: Adjust to today's change to gnulib-tool by invoking
3919 it with --assume-autoconf='latest-stable'.
3921 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
3923 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
3924 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
3926 * src/muscle_tab.h (muscle_grow): Replace the header comments with
3927 those from muscle_tab.c since the old ones are misleading.
3929 2006-07-13 Akim Demaille <akim@epita.fr>
3931 Support %define "KEY" {VALUE}.
3932 * src/scan-code.h, src/scan-code.l (translate_action)
3933 (translate_rule_action, translate_symbol_action, translate_code):
3934 Return char *, not const char *.
3935 * src/parse-gram.y (declaration): Rename as...
3936 (prologue_declaration): this.
3937 (string_content): Remove this nonterminal, use STRING.
3938 (braceless, content, content.opt): New nonterminal.
3940 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
3942 * src/scan-gram.l (getargs.h): Don't include it.
3944 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
3946 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
3947 rather than a for-loop that declares a local bool variable. This
3948 should work around a compatibility problem with a Cray x1e C++
3949 compiler reported by Hung Nguyen in
3950 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
3951 The for-loop was introduced in the 2004-11-17 change but I don't
3952 know why it was needed.
3954 2006-07-12 Akim Demaille <akim@epita.fr>
3956 * data/c.m4: Comment changes.
3958 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
3960 * src/complain.c (error_message, ERROR_MESSAGE): New.
3962 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
3963 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
3965 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
3967 * NEWS: Instead of %union, you can define and use your own union type
3968 YYSTYPE if your grammar contains at least one <type> tag.
3969 Your YYSTYPE need not be a macro; it can be a typedef.
3970 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
3971 (Union Decl, Decl Summary): Document this.
3972 * data/glr.c (YYSTYPE): Implement this.
3973 * data/glr.cc (YYSTYPE): Likewise.
3974 * data/lalr1.cc (YYSTYPE): Likewise.
3975 * data/yacc.c (YYSTYPE): Likewise.
3976 * src/output.c (prepare): Output tag_seen_flag.
3977 * src/parse-gram.y (declaration, grammar_declaration):
3978 Use 'union_seen' rather than 'typed' to determine whether
3979 %union has been seen, since grammars can now be typed without
3981 (symbol_declaration, type.opt, symbol_def):
3982 Keep track of whether a tag has been seen.
3983 * src/reader.c (union_seen, tag_seen): New vars.
3985 * src/reader.h (union_seen, tag_seen, typed): Likewise.
3986 * src/scan-code.l (untyped_var_seen): New variable.
3987 (handle_action_dollar): Adjust to above changes.
3988 (handle_action_dollar, handle_action_at):
3989 Improve overflow checking for outlandish numbers.
3990 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
3991 avoid new diagnostics generated by above changes.
3992 * tests/regression.at (YYSTYPE typedef): Add test to check
3993 for type tags without %union.
3995 * src/symlist.c (symbol_list_length): Return int, not unsigned
3996 int, since callers expect int. This may need to get revisited
3997 once we have proper integer overflow checking.
3999 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
4000 object is now static.
4002 * src/getargs.c (flags_argmatch): Return void, not int,
4003 to pacify ./configure --enable-gcc-warnings.
4005 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
4006 since last_string is already defined to FLEX_PREFIX (last_string).
4008 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4010 Implement --warnings/-W.
4011 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
4013 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
4015 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
4016 (warnings_args, warnings_types): New.
4017 (getargs, short_options, long_options): Accept -W/--warnings.
4018 Sort the options by alphabetical order, upper case letter right
4019 before its lower case.
4021 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4023 Change %merge result type clash warnings to errors. Discussed at
4024 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
4025 * src/reader.c (record_merge_function_type): Use complain_at.
4026 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4027 declared later): Update test case results.
4029 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4031 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
4032 to be in alphabetical order.
4033 (trace_args): Spelling fixes.
4035 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4037 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
4038 so they don't collide with user-defined macros.
4039 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4040 this was never guaranteed, and now that we're using gnulib stdint,
4041 which defines int_fast16_t to long int, the problem is exposed.
4043 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
4045 * data/c.m4 (b4_basename): Simplify a bit, since we don't
4046 need the full POSIX semantics (and weren't implementing them
4049 Adjust to Autoconf 2.60 and today's gnulib.
4050 * bootstrap (gnulib_modules): Add stdint.
4051 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4052 no longer copies it.
4053 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4054 since stdint needs the former and wcwidth (which is now required
4055 by mbswidth) needs the latter.
4056 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4057 work around a compatibility glitch between gettext 0.14.6 and
4059 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
4060 Do not check for uintptr_t, since new stdint module does the right
4062 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
4063 Add stdint.h, stdint_.h, wcwidth.h.
4064 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
4065 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
4066 stdint.m4, wchar_t.m4, wcwidth.m4.
4067 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
4068 usual order for ../lib/*.h files.
4069 (file_name_split): Use last_component, not base_name, to adjust
4071 * src/parse-gram.h: Include <strverscmp.h> in the usual order
4072 for ../lib/*.h files.
4073 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
4074 Define unconditionally, since we now assume the stdint module.
4075 * src/scan-skel.l: Include <dirname.h>.
4076 (BASE_QPUTS): Use last_component, not base_name.
4077 * src/system.h: Include <unlocked-io.h> in the usual order
4078 for ../lib/*.h files. Include <stdint.h> unconditionally,
4079 since we now use the stdint module.
4080 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
4081 HAVE_UINTPTR_T, since we now use the stdint module.
4082 (base_name): Remove decl, since files now include <dirname.h>
4085 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4087 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
4089 * data/yacc.c, data/glr.c, data/location.cc: Use them.
4090 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
4092 * tests/calc.at: Adjust.
4094 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4096 * data/c.m4 (b4_basename): New.
4097 (b4_syncline): Also output the location of its invocation (from
4099 (b4_user_action, b4_define_user_action, b4_user_actions)
4100 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
4101 (b4_user_stype): New.
4102 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
4104 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4106 In the grammar file, the first column is 1 not 0 on the first line as
4107 on every other line.
4108 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
4109 * tests/input.at (Torturing the Scanner): Update output.
4111 * src/scan-gram.l (scanner_cursor): Declare it static.
4113 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4115 In warnings, say "previous declaration" rather than "first
4117 * src/symtab.c (redeclaration): Do that here.
4118 * src/reader.c (record_merge_function_type): In the case of a result
4119 type clash, report the previous declaration rather than the very first
4120 one in the grammar file.
4121 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4122 declared later): Add a third declaration to check this behavior.
4123 * tests/input.at (Incompatible Aliases): Update output.
4125 2006-06-27 Akim Demaille <akim@epita.fr>
4127 * doc/Doxyfile.in: New.
4128 * doc/Makefile.am: Use it.
4129 * src/lalr.h, src/symtab.h: Initial doxygenation.
4131 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4133 Don't miss %merge result type warnings just because the LHS types are
4134 declared after the %merge. This continues the effort of the previous
4136 * src/reader.c (get_merge_function): Don't set the merger type yet.
4137 (record_merge_function_type): New function for setting the merger type
4138 and checking for clashes.
4139 (grammar_current_rule_merge_set): Set the location of the %merge for
4141 (packgram): Invoke record_merge_function_type for each rule now that
4142 all symbol type declarations have been parsed.
4143 * src/reader.h (merger_list.type_declaration_location): New member
4144 storing the location of the first %merge from which the type for this
4145 merging function was derived.
4146 * src/symlist.h (symbol_list.merger_declaration_location): New member
4147 storing the location of a rule's %merge, if any.
4148 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4149 declared later): New test to catch the error fixed by the above patch.
4151 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4153 Get action warnings (grammar_rule_check) right even when symbol
4154 declarations appear after the rules. Discussed at
4155 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
4157 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
4158 Don't mistake the type of $$ in a midrule to be that of its parent
4160 * src/reader.c (grammar_current_rule_end): Don't invoke
4161 grammar_rule_check yet since not all symbol declarations may have been
4163 (grammar_midrule_action): Likewise.
4164 Don't record whether the midrule's $$ has been used yet since actions
4165 haven't been translated yet.
4166 Record the midrule's parent rule and its RHS index within the parent
4168 (grammar_current_rule_action_append): Don't translate the action yet
4169 since not all symbol declarations may have been parsed yet and, thus,
4170 warnings about types for $$, $n, @$, and @n can't be reported yet.
4171 (packgram): Translate the action and invoke grammar_rule_check now that
4172 all symbol declarations have been parsed.
4173 * src/scan-code.l (handle_action_dollar): Now that this is invoked
4174 after parsing the entire grammar file, the symbol list here in the case
4175 of a midrule is actually the midrule's empty RHS, so reference its
4176 parent rule's RHS where necessary.
4177 On the other hand, now that you can already know it's a midrule, you
4178 aren't forced to think $$ has the same type as its parent rule's $$.
4179 (handle_action_at): In the case of a midrule, reference the parent rule
4181 * src/symlist.c (symbol_list_new): Initialize new midrule-related
4183 (symbol_list_length): Now that this is invoked after all rules have
4184 been parsed, a NULL symbol (rather than a NULL symbol list node)
4185 terminates a rule. symbol_list_print already does this correctly.
4186 * src/symlist.h (symbol_list.midrule_parent_rule,
4187 symbol_list.midrule_parent_rhs_index): New members so that midrules can
4188 remember their relationships with their parents.
4189 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
4190 fixed by the above patch.
4191 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
4193 (Unused values): ... this old test case and...
4194 (Unused values before symbol declarations): ... this new test case.
4195 This one is the same as `Unused values' except that all symbol
4196 declarations appear after the rules in order to catch the rest of the
4197 errors fixed by the above patch.
4199 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4202 * src/reader.c (current_rule): Declare it static since it's no longer
4203 used outside this file.
4204 (grammar_current_rule_action_append): Remove redundant arguments from
4205 translate_rule_action invocation.
4206 * src/reader.h (current_rule): Remove this unused extern.
4207 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
4208 * src/scan-code.l (translate_rule_action): Likewise.
4210 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
4212 Clean up yesterday's patch.
4213 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
4215 * src/reader.c (grammar_current_rule_action_append): ... here for
4216 consistency with grammar_current_rule_symbol_append.
4217 * tests/regression.at (Braced code in declaration in rules section):
4218 Make yyerror and yylex static as usual.
4220 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
4222 Fix bug that mistakes braced code in a declaration in the rules section
4223 to be a rule action. Mentioned at
4224 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
4225 * src/scan-gram.l: Move midrule action detection from the start of the
4226 scanning of any braced code to...
4227 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
4228 action. For readability, use $2 and @2 rather than the equivalent
4230 * tests/regression.at (Braced code in declaration in rules section):
4231 New test to catch the error fixed by the above patch.
4233 Work on code readability some.
4234 * src/scan-code.l (current_rule): Get rid of this misleading and
4235 redundant declaration: it's actually extern'ed in reader.h.
4236 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
4237 translate_action): Add a rule argument and use it instead of the global
4239 (translate_rule_action): This already receives current_rule through an
4240 argument, so pass it on to translate_action instead of assigning
4241 current_rule to current_rule.
4242 (translate_symbol_action, translate_code): Pass rule = NULL to
4245 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
4247 Rename %before-definitions to %start-header and %after-definitions to
4248 %end-header. Don't use these declarations to separate pre-prologue
4249 blocks from post-prologue blocks. Add new order-independent
4250 declarations %before-header and %after-header as alternatives to the
4251 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
4252 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
4253 * NEWS (2.3+): Update for these changes.
4254 * data/glr.c (b4_before_definitions): Update to...
4255 (b4_start_header): ... this.
4256 (b4_after_definitions): Update to...
4257 (b4_end_header): ... this.
4258 * data/glr.cc: Likewise.
4259 * data/lalr1.cc: Likewise.
4260 * data/yacc.c: Likewise.
4261 * doc/bison.texinfo (The prologue): Update names, and replace remaining
4262 prologue blocks with %*-header declarations.
4263 (Calc++ Parser): Likewise.
4264 (Decl Summary): Update names.
4265 (Table of Symbols): Update description.
4266 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
4267 (PERCENT_END_HEADER): ... this.
4268 (PERCENT_BEFORE_DEFINITIONS): Update to...
4269 (PERCENT_START_HEADER): ... this.
4270 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4271 (declaration): Update token names and m4 macro names.
4272 When parsing %end-header and %start-header, invoke translate_code
4273 before muscle_code_grow, and no longer set global booleans to remember
4274 whether these declarations have been seen.
4275 Parse new %after-header and %before-header.
4276 * src/reader.c (before_definitions, after_definitions): Remove.
4277 (prologue_augment): Accept a new bool argument to specify whether to
4278 augment the pre-prologue or post-prologue.
4279 * src/reader.h (before_definitions, after_definitions): Remove these
4281 (prologue_augment): Add new bool argument.
4282 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
4283 (PERCENT_END_HEADER): ... this.
4284 (PERCENT_BEFORE_DEFINITIONS): Update to...
4285 (PERCENT_START_HEADER): ... this.
4286 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4287 * tests/actions.at (Printers and Destructors): Update names.
4289 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
4291 Add comparison operators for C++ location classes. Discussed at
4292 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
4293 * data/c++.m4 (b4_define_location_comparison): New boolean %define
4294 declaration indicating whether filename_type has an operator==. If
4295 filename_type is `std::string', it defaults to `1', `0' otherwise.
4296 * data/location.cc: Iff b4_define_location_comparison is `1', add
4297 operator== and operator!= for class position and for class location.
4300 * src/scan-action.l: Remove unused file.
4301 * src/symtab.c (symbol_printer_set): Use printer_location not
4302 destructor_location.
4303 * src/symtab.h (struct symbol): Replace incorrect source comment for
4305 * tests/input.at (Incompatible Aliases): Update output with correct
4308 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
4310 Don't put the pre-prologue in the header file. For the yacc.c code
4311 file and the glr.c header and code files, move the pre-prologue before
4312 the token definitions. Add new %before-definitions and
4313 %after-definitions to declare code that will go in both the header file
4314 and code file. Discussed at
4315 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
4316 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
4318 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
4319 * NEWS (2.3+): Describe these changes.
4320 * data/glr.c (b4_pre_prologue): Move from within to before...
4321 (b4_shared_declarations): ... this.
4322 Add new b4_before_definitions before b4_token_enums.
4323 Add new b4_after_definitions at the end.
4324 * data/glr.cc (b4_pre_prologue): Replace with...
4325 (b4_before_definitions): ... this in the header file.
4326 (b4_after_definitions): New near the end of the header file.
4327 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
4328 code file right before including the header file.
4329 (b4_before_definitions): New in the previous position of
4330 b4_pre_prologue in the header file.
4331 (b4_after_definitions): New near the end of the header file.
4332 * data/yacc.c: Clean up some m4 quoting especially in the header file.
4333 (b4_token_enums_defines): In the code file, move to right before
4334 YYSTYPE for consistency with the header file.
4335 (b4_before_definitions): New right before b4_token_enums_defines in
4336 both the header and code file.
4337 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
4338 header and code file.
4339 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
4340 of prologues for %union dependencies.
4341 (Decl Summary): In %defines description, mention the effect of
4342 %before-definitions and %after-definitions on the header file.
4343 (Calc++ Parser): Forward declare driver in a %before-definitions rather
4344 than in the pre-prologue so that make check succeeds.
4345 (Table of Symbols): Add entries for %before-definitions and
4347 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
4348 %before-definitions.
4349 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
4350 (declaration): Parse those declarations and append to
4351 b4_before_definitions and b4_after_definitions, respectively.
4352 * src/reader.c (before_definitions, after_definitions): New bools to
4353 track whether those declarations have been seen.
4354 (prologue_augment): Add to the post-prologue if %union,
4355 %before-definitions, or %after-definitions has been seen.
4356 * src/reader.h (before_definitions, after_definitions): New extern's.
4357 * src/scan-gram.l: Scan the new declarations.
4358 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
4359 prologue block in a %before-definitions or a %after-definitions based
4360 on whether the %union is declared.
4361 * tests/regression.at (Early token definitions with --yacc, Early token
4362 definitions without --yacc): Move tests for token definitions into the
4363 post-prologue since token names are no longer defined in the
4366 2006-06-20 Akim Demaille <akim@epita.fr>
4368 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
4369 (symbol_get): Use it.
4370 * src/parse-gram.y: Use it.
4372 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
4374 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
4375 build succeeds when configured with --enable-gcc-warnings.
4377 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4379 * src/parse-gram.y (char_name): New function.
4380 (CHAR, STRING, string_content): For %printer, properly escape.
4381 (ID): Prefer fputs to fprintf.
4382 (id): Reindent to be consistent with other rules.
4383 Properly quote char.
4385 The Translation Project changed its way of publishing translations
4386 to maintainers. I haven't received any responses to my request
4387 for supporting the old way, or for documenting the new way. I
4388 have modified 'bootstrap' to use screen scraping
4389 (in this case, HTML scraping). This is unreliable and inelegant,
4390 but I don't see any better way. Yuck.
4391 * bootstrap (TP_URL, WGET_COMMAND): New vars.
4392 (get_translations): New function, which uses HTML scraping to
4393 deduce locations of latest translations.
4394 Use this function to grab both bison and bison-runtime .po files.
4395 Don't bother priming the pump for the runtime-po domain any more,
4396 as it's now translated better than bison is.
4398 2006-06-19 Akim Demaille <akim@epita.fr>
4400 * src/scan-gram.l: No longer "parse" things after `%union' until
4401 `{'. Rather, return a single "%union" token.
4402 No longer make symbols: return strings, and leave the conversion
4403 to symbols to the parser.
4404 (SC_PRE_CODE, token_type): Remove.
4405 * src/parse-gram.y (%union): New field `character'.
4408 (ID, ID_COLON): Now that the scanner no longer makes them
4409 identifiers, adjust all uses to invoke symbol_get.
4410 (id_colon): New, wraps the conversion from string to symbol.
4411 (%union): Accept a possible union_name.
4412 (symbol): Now can be a char.
4413 * data/c.m4 (b4_union_name): Leave a default value.
4414 * data/glr.c, data/yacc.c: Use it.
4416 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
4418 For associating token numbers with token names for "yacc.c", don't use
4419 #define statements unless `--yacc' is specified; always use enum
4420 yytokentype. Most important discussions start at:
4421 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
4422 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
4424 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
4425 * NEWS (2.3+): Mention.
4426 * data/c.m4 (b4_yacc_if): New.
4427 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
4429 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
4430 on token name definitions.
4431 * src/getargs.c (usage): Capitalize `Yacc' in English.
4432 * src/output.c (prepare): Define b4_yacc_flag.
4433 * tests/regression.at (Early token definitions): Test that tokens names
4434 are defined before the pre-prologue not just before the post-prologue.
4435 Remove this test case and copy to...
4436 (Early token definitions with --yacc): ... this to test #define's.
4437 (Early token definitions without --yacc): ... and this to test enums.
4439 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
4441 * NEWS: Reword the post-2.3 change to not be so optimistic about
4442 removing the old "look-ahead" spelling.
4443 Update previous look-ahead/lookahead change reports.
4444 * REFERENCES: look-ahead -> lookahead (since that's
4445 what he actually wrote).
4446 * doc/refcard.tex: look ahead -> lookahead,
4447 look-ahead -> lookahead
4449 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
4451 For consistency, use `lookahead' instead of `look-ahead' or
4452 `look_ahead'. Discussed starting at
4453 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
4455 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.
4456 * NEWS: For the next release, note the change to `--report'.
4457 * TODO, doc/bison.1: Update English.
4458 * doc/bison.texinfo: Update English.
4459 (Understanding Your Parser, Bison Options): Document as
4460 `--report=lookahead' rather than `--report=look-ahead'.
4461 * src/conflicts.c: Update English in comments.
4462 (lookahead_set): Rename from look_ahead_set.
4463 (flush_reduce): Rename argument look_ahead_tokens to lookahead_tokens.
4464 (resolve_sr_conflict): Rename local look_ahead_tokens to

4528 * TODO: Add request from Nelson H. F. Beebe to be able to install
4529 Bison without installing the yacc script.
4531 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
4533 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
4534 and yytext if they're already #define'd.
4535 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...

4546 loc argument as it shadows a global.

4564 2006-06-06 Akim Demaille <akim@epita.fr>
4566 Extract the parsing of user actions from the grammar scanner.
4567 As a consequence, the relation between the grammar scanner and
4568 parser is much simpler. We can also split "composite tokens" back
4570 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
4571 * src/scan-gram.l (add_column_width, adjust_location): Move to and
4573 * src/location.h, src/location.c (add_column_width)
4574 (location_compute): these.
4575 Fix the column count: the initial column is 0.
4576 (location_print): Be robust to ending column being 0.
4577 * src/location.h (boundary_set): New.
4578 * src/main.c: Adjust to scanner_free being renamed as
4580 * src/output.c: Include scan-code.h.
4581 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
4583 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
4584 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
4585 which is now, again, a separate token.
4586 Adjust all dependencies.
4587 Whereever actions with $ and @ are used, use translate_code.
4588 (action): Remove this nonterminal which is now useless.
4589 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.

4627 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4629 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4630 Use Akim's wording from
4631 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
4633 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4635 Between Bison releases, manually append `+' to the previous Bison
4636 release number, and use that as a signal to automatically print the
4637 ChangeLog's CVS Id keyword from --version. Discussed starting at
4638 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
4639 * ChangeLog: Add Id header.
4640 * configure.ac (AC_INIT): Append `+' to `2.3'.
4641 * src/.cvsignore: Add revision.c.
4642 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
4643 (BUILT_SOURCES): Add revision.c.
4644 (revision.c): New target rule. This file defines a new global variable
4645 named revision. It initializes it with either the Id from ChangeLog
4646 or, if VERSION doesn't contain `+', with the empty string.
4647 * src/getargs.c (version): Print the value of revision.
4648 * src/revision.h: Extern revision.
4650 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4652 * NEWS: Version 2.3.
4653 * configure.ac (AC_INIT): Likewise.
4655 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4657 * data/glr.c (YYRECOVERING): Define to be a function-like macro
4658 with no arguments, not as an object-like macro. This is for
4659 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
4660 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
4661 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
4664 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
4666 * src/getargs.c (usage): Back out yesterday's modification of the
4667 --help output so that we don't have to wait for translation before
4670 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4672 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
4673 Problem reported by Akim Demaille.
4675 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4677 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4679 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4681 * data/yacc.c (yy_reduce_print): Omit trailing white space in
4682 generated source code. Problem reported by Frans Englich in
4683 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
4685 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
4687 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
4688 shell, not within 'make', so that 'make' by an ordinary builder
4689 (using GNU make) does not worry about configuring gzip. This also
4690 works around a bug reported independently by Keith Thompson and by
4691 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
4692 stderr rather than stdout, messing up the build logs.
4694 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4696 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
4697 to make sure that YYID will never be unused. This fixes a 'make
4698 maintainer-check' failure caused by the recent changes to the 'Trivial
4699 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
4701 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
4703 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4705 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
4706 state before an empty RHS is always resolved here. Only the location
4707 of that state is guaranteed to be resolved, and that's enough. This
4708 fixes the remaining bug reported by Derek M. Jones in
4709 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4710 * tests/glr-regression.at (Uninitialized location when reporting
4711 ambiguity): Test the above case.
4712 Also, the embedded comments in this test case claim it checks the case
4713 of an empty RHS that has inherited the initial location. However, the
4714 corresponding LHS was already resolved, so yyresolveLocations didn't
4715 actually have reason to modify it. Fix this by forcing
4716 nondeterministic operation at the beginning of the parse.
4718 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4720 * data/c.m4 (b4_yy_symbol_print_generate):
4721 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
4722 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
4723 of the bugs reported today by Derek M Jones in
4724 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4725 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
4726 defined to be a type name without parens or brackets.
4727 (Location Type): Similarly for YYLTYPE.
4728 * tests/regression.at (Trivial grammars): Put in a test for this
4729 bug that will be caught by 'make maintainer-check' (though not,
4730 alas, by 'make check' unless your compiler is picky).
4732 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4734 * NEWS: Version 2.2.
4735 * configure.ac (AC_INIT): Likewise.
4737 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
4739 * data/glr.c (yyreportTree): Make room in yystates for the state
4740 preceding the RHS. This fixes the segmentation fault reported by Derek
4742 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
4743 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
4744 to the user. Reported for yyreportTree by Derek M. Jones later in the
4746 * THANKS: Add Derek M. Jones.
4747 Update my email address.
4748 Fix typo in Steve Murphy's name.
4750 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4752 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
4753 checking against YYLAST that caused the parser to miss a potential
4754 alternative in its diagnostic.
4755 Problem reported by Maria Jose Moron Fernandez in
4756 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
4757 * data/lalr1.cc (yysyntax_error_): Likewise.
4758 * data/yacc.c (yysyntax_error): Likewise.
4759 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
4760 tokens, in case we run into an older C compiler.
4761 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
4762 Use them to check for the off-by-one error fixed above.
4764 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
4765 YYSIZE_T, not size_t.
4766 * tests/regression.at (Trivial grammars): New test, to catch
4767 the error fixed by the above patch.
4769 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4771 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
4773 Reported by Steve Murphy.
4775 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4777 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
4778 * data/glr.cc: b4_location_flag is now b4_locations_flag.
4780 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4782 Implement --trace=m4.
4783 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
4784 * src/output.c (output_skeleton): When set, pass -dV to m4.
4786 Factor the handling of flags in m4.
4787 * src/output.c (prepare): Rename the muscle names debug, defines,
4788 error_verbose to debug_flag, defines_flag, error_verbose_flag.
4789 * data/c.m4: Adjust.
4790 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
4791 Use b4_define_flag_if to define other b4_FLAG_if macros.
4792 (b4_location_if): As a consequence, rename as...
4793 (b4_locations_if): this, for consistency.
4794 Adjust all the skeletons.
4796 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4798 * etc/bench.pm: Shorten bench names.
4800 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4802 * src/output.h, src/output.c (error_verbose): Move to...
4803 * src/getargs.h, src/getargs.c: here.
4805 Adjust dependencies.
4807 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4809 * data/c.m4 (b4_copyright): Put the special exception for Bison
4810 skeletons here, so we don't have to put it in each skeleton. All
4811 uses changed. Suggested by Akim Demaille. Also, wrap the
4812 copyright notice, in case it is longer than 80 columns. Replace
4813 comma by newline after title.
4815 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4817 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
4818 incompatibility, not a bug. Mention that it wasn't fixed as of
4821 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4823 * examples/extexi: Enforce the precedence of concatenation over
4825 Reported by Tommy Nordgren.
4827 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4829 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
4830 with the member "token".
4831 Reported by Martin Nylin.
4833 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
4835 * data/glr.c: Switch to Bison 2.2 special-exception language in
4836 the copyright notice. Use more-regular format for titles and

4848 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4850 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
4851 that variable and the line breaks the bootstrap. Problem reported
4852 by Juan M. Guerrero.
4854 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

4872 Problem reported by Bob Rossi.
4874 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
4876 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
4877 and didn't really work.
4878 For the index, use @ifnotinfo, not @iftex.
4879 Minor cleanups of spacing and terminology.
4881 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4883 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
4884 of AT_NAME_PREFIX when %name-prefix is not used.
4886 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4888 Apply --prefix to C++ skeletons too: they change the namespace.
4889 The test suite already exercize these cases.
4890 * data/c++.m4 (b4_namespace): New.
4891 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.

4893 * data/yacc.c, data/glr.c: Remove a useless `[]'.
4894 * doc/bison.texinfo: Document it.

4941 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
4942 page. Say "you can use it" not "you may use it" as on the web page;
4943 we're describing capabilities not granting permission.
4945 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
4947 * data/glr.c (yyresolveLocations): Rename local variables to avoid
4948 shadowing warnings. Use usual patter for iterating through RHS.
4949 * tests/glr-regression.at
4950 (Uninitialized location when reporting ambiguity):
4951 Modify yylex so that it uses its argument, rather than trying
4952 to rely on ARGSUSED (which doesn't work for gcc with warnings).
4953 const char -> char const.
4955 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
4956 Don't use tabs inside commands; it messes up 'ps'.
4957 Problem reported by twlevo.
4959 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
4961 * tests/glr-regression.at (Uninitialized location when reporting
4962 ambiguity): New test case.
4963 * data/glr.c (yyresolveLocations): New function, which uses
4965 (yyresolveValue): Invoke yyresolveLocations before reporting an
4967 * doc/bison.texinfo (Default Action for Locations): Note
4968 YYLLOC_DEFAULT's usage for ambiguity locations.
4969 (GLR Semantic Actions): Cross-reference those notes.
4971 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
4973 * tests/glr-regression.at (Leaked semantic values when reporting
4974 ambiguity): Remove unnecessary union and type declarations.
4975 (Leaked lookahead after nondeterministic parse syntax error): New test
4977 * data/glr.c (yyparse): Check for zero stacks remaining before
4978 attempting to shift the lookahead so that you don't lose it.
4980 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
4982 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
4983 * tests/glr-regression.at (Leaked semantic values when reporting
4984 ambiguity): New test case.
4985 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
4986 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
4987 now unnecessary yystackp parameter.
4988 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
4989 destructors can be called.
4991 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
4992 in existing testcases.
4994 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
4996 Don't leak semantic values for parent RHS when a user action cuts the
4997 parser, and clean up related code a bit.
4998 * tests/glr-regression.at (Leaked merged semantic value if user action
4999 cuts parse): Rename to...
5000 (Leaked semantic values if user action cuts parse): ... this. Add check
5001 for leaked parent RHS values.
5002 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
5003 between an unresolved state (non-empty chain of semantic options) and
5004 an incomplete one (signaled by an empty chain).
5005 (yyresolveStates): Document the interface. Move all manipulation of a
5006 successfully or unsuccessfully resolved yyGLRState to...
5007 (yyresolveValue): ... here so that yyresolveValue always leaves a
5008 yyGLRState with consistent data and thus is easier to understand.
5009 Remove the yyvalp and yylocp parameters since they are always just
5010 taken from the yys parameter. When reporting a discarded merged value
5011 in debugging output, note that it is incompletely merged. Document the
5013 (yyresolveAction): If resolving any of the RHS states fails, destroy
5014 them all rather than leaking them. Thus, as long as user actions are
5015 written to clean up the RHS correctly, yyresolveAction always cleans up
5016 the RHS of a semantic option. Document the interface.

5026 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
5027 mid-rule action inside a nonterminal symbol in order to declare a
5028 destructor for its semantic value.

5035 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||

5038 incompatible declarations (using 'throw') C++'s stdlib.h. This
5039 should fix Debian bug 340012

5080 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
5082 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
5083 nodist_PROGRAMS, since we don't need to actually compile the
5084 example if we're just doing a plain 'make'. This avoids bothering
5085 the installer unnecessarily about problems due to weird C++

5092 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
5093 than #include "...", and compile with -I'.'. The old method was
5094 not portable, according to Posix and the C standard, and it does
5095 not work with Sun C 5.7, where previous #line directives affect
5096 the working directory used in later #include "..." directives.

5115 that '#include <string>' works.
5117 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
5118 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
5119 "warning: sorry: semantics of inline function static data `const
5120 unsigned char translate_table[262]' are wrong (you'll wind up with

5124 or, xor to not_, and_, or_, and xor_, respectively. This works
5125 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
5126 random system header somewhere that includes the equivalent of

5135 During deterministic GLR operation, user actions should be able to
5136 influence the parse by changing yychar. To make this easier to fix and
5137 to make glr.c easier to evolve in general, don't maintain yytoken in
5138 parallel with yychar; just compute yytoken when needed.

5140 GLR): Check that setting yychar in a user action has the intended

5145 yychar rather than *yytokenp to determine the current lookahead.
5146 Compute yytoken locally when needed.

5165 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
5166 got from <http://bro-ids.org/download.html>. The bug is that
5167 when two actions appeared in succession, the second one was
5168 scanned before the first one was added to the grammar rule
5169 as a midrule action. Bison then output the incorrect warning
5170 "parse.y:905.17-906.36: warning: unused value: $3".
5171 * src/parse-gram.y (BRACED_CODE, action): These are no longer
5172 associated with a value.

5175 * src/reader.c (grammar_midrule_action): Now extern.
5176 (grammar_current_rule_action_append): Don't invoke
5177 grammar_midrule_action; that is now the scanner's job.

5185 * tests/input.at (AT_CHECK_UNUSED_VALUES):
5186 Add some tests to check that the above changes fixed the bug.
5188 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
5190 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
5191 All used changed. Check whether the symbol has a destructor,
5192 not whether it is typed.
5193 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so

5394 (copyright-check): Use current year instead of hardwiring 2005.
5395 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
5396 (announcement): Add --gpg-key-ID.
5398 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
5401 Avoid undefined behavior that addressed just before the start of an
5402 array. Problem reported by twlevo.

5426 * doc/bison.texinfo: Fix some typos.
5427 (GLR Semantic Actions): New subsection discussing special
5428 considerations because GLR semantic actions might be deferred.
5429 (Actions): Mention look-ahead usage of yylval.
5430 (Actions and Locations): Mention look-ahead usage of yylloc.
5431 (Special Features for Use in Actions): Add YYEOF entry and mention it
5432 in the yychar entry.
5433 In the yychar entry, remove mention of the local yychar case (pure
5434 parser) since this is irrelevant information when writing semantic
5435 actions and since it's already discussed in `Table of Symbols' where
5436 yychar is otherwise described as an external variable.
5437 In the yychar entry, don't call it the `current' look-ahead since it
5438 isn't when semantic actions are deferred.
5439 In the yychar and yyclearin entries, add note about deferred semantic
5441 Add yylloc and yylval entries discussing look-ahead usage.
5442 (Look-Ahead Tokens): When discussing yychar, don't call it the
5443 `current' look-ahead, and do mention yylval and yylloc.
5444 (Error Recovery): Cross-reference `Action Features' when mentioning
5446 (Table of Symbols): In the yychar entry, don't call it the `current'
5448 In the yylloc and yylval entries, mention look-ahead usage.

5452 * tests/glr-regression.at: Update copyright year to 2006.
5454 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
5456 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
5457 use during nondeterministic operation to track which stacks have
5458 actually needed the current lookahead.
5459 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
5460 Allocate, deallocate, resize, and otherwise shuffle space for
5461 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
5462 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
5463 appropriately during nondeterministic operation.
5464 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
5465 members to store the current lookahead to be used by the deferred
5467 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
5468 from which the RHS is taken. Set the lookahead members of the new
5469 yySemanticOption according to the lookahead status for stack yyk.

5471 yyaddDeferredAction.
5472 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
5473 members of yySemanticOption before invoking yyuserAction, and then set

5478 titles for consistency.
5479 (Leaked merged semantic value if user action cuts parse): In order to
5480 suppress lint warnings, use arguments in merge function, and assign
5481 char value < 128 in main.
5482 (Incorrect lookahead during deterministic GLR): New test case.
5483 (Incorrect lookahead during nondeterministic GLR): New test case.
5485 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

5494 * tests/glr-regression.at: For consistency with my newer test cases,
5497 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5499 * data/glr.c (yyresolveValue): When merging semantic options, if at
5500 least one user action succeeds but a later one cuts the parse, then
5501 destroy the semantic value before returning rather than leaking it.
5502 (yyresolveStates): If a user action cuts the parse and thus
5503 yyresolveValue fails, ignore the (unset) semantic value rather than
5504 corrupting the yyGLRState, and empty the semantic options list since
5505 the user actions should have called all necessary destructors.
5506 Simplify code with YYCHK.
5507 * tests/glr-regression.at (Corrupted semantic options if user action
5508 cuts parse): New test case.
5509 (Undesirable destructors if user action cuts parse): New test case.
5510 Before applying any of this patch, this test case never actually failed
5511 for me... but only because the corrupted semantic options usually

5553 * doc/bison.texinfo (Bison Options): Say more accurately what
5555 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
5556 about declarations in the grammar when in Yacc mode, as POSIX does
5557 not require a diagnostic when the grammar uses extensions.
5559 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
5561 Warn about dubious constructions like "%token T T".
5563 * src/symtab.h (struct symbol.declared): New member.

5585 (b4_parse_param): Improve its definition, and bound it more
5586 clearly in the skeleton.
5587 (b4_epilogue): Append, instead of prepending, in order to keep
5589 Simplify the generation of auxiliary functions: locations and
5590 purity are mandated.
5591 (b4_global_tokens_and_yystype): Honor it.
5592 * data/location.cc (c++.m4): Don't include it.
5593 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
5595 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of

5630 (rule_length_overflow, increment_rule_length, add_column_width):
5632 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
5633 (<SC_BRACED_CODE>"}"):
5634 Use increment_rule_length rather than incrementing it by hand.
5635 (adjust_location, handle_syncline): Diagnose overflow.
5636 (handle_action_dollar, handle_action_at):
5637 Fix bug with monstrosities like $-2147483648.

5667 values, check that the warning is issued.
5669 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>

5706 Undo 2005-12-01 tentative license wording change. The wording is
5707 still being reviewed by the lawyers, and we don't want to wait for
5708 them before publishing a test release. For now, revert to the

5730 * tests/cxx-type.at: Construct a tree, count the parents of shared
5731 nodes, and free each node once and only once. Previously, the memory
5732 for semantic values was leaked instead.
5734 2005-12-21 Joel E. Denny <address@hidden>
5736 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.

5751 `if (YYID (N))' to pacify lint.
5753 2005-12-21 Akim Demaille <akim@epita.fr>
5755 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
5756 destroy the RHS symbols of a rule.
5757 * data/yacc.c (yylen): Initialize to 0.
5758 Keep its value to the number of items to possibly shift.
5759 In particular, a regular successful parse that ends on YYFINAL by
5760 a (internal) YYACCEPT must not have yylen != 0.
5761 (yyerrorlab, yyreturn): Pop the RHS.
5762 Reorder a bit to emphasize the `shifting' bits of code.

5773 * djgpp/config.bat: Replace every occurence of the file name
5774 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
5775 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
5776 * djgpp/config.sed: Replace every occurence of the file name
5777 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

5806 * tests/sets.at (Accept): Fix typos in regular expression used to
5807 sed out the final state number.
5809 Work around portability problem on Solaris 10: flex-generated
5810 files include <stdio.h> before <config.h>, which messes up
5811 because the latter defines __EXTENSIONS__. Address the problem
5812 by creating two new little files that include <config.h> first,
5813 then include the flex-generated files. Rewrite everyone else
5814 to include <config.h> first, as well.
5815 * lib/timevar.c: Always include "config.h".

6154 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
6156 Undo the parts of the unlocked-I/O change that substituted

6158 but some people prefer the printf style.

6189 Use unlocked I/O for a minor performance improvement on hosts like
6190 GNU/Linux and Solaris that support unlocked I/O. The basic idea

6354 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
6355 Trivial changes from Joel E. Denny.
6357 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
6359 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
6360 don't use alloca any more.
6362 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
6363 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
6364 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
6365 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
6366 to match yacc.c, to test more hosts.
6368 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
6370 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
6371 doesn't affect behavior.
6372 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
6374 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
6375 This works a bit better with glibc, if user code has already included
6377 * doc/bison.texinfo (Bison Parser): Document that users can't
6378 arbitrarily use malloc and free for other purposes. Document
6379 that <alloca.h> and <malloc.h> might be included.
6380 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
6381 user must declare alloca.
6383 * HACKING (release): Forwarn the Translation Project about
6386 2005-09-20 Akim Demaille <akim@epita.fr>
6388 * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
6390 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
6392 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
6393 (YYSTACK_ALLOC_MAXIMUM): Use it.
6394 (yysyntax_error): New function.
6395 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
6396 multiple syntax errors are reported, and alloca is being used.
6397 Instead, reallocate buffers twice as big each time, so that
6398 we waste at most half the allocated memory. Start with a small
6399 (128-byte) buffer that will suffice in most cases anyway.
6400 Use yysyntax_error to do most of the work.
6402 * doc/bison.texinfo (Error Reporting, Table of Symbols):
6403 yynerrs is the number of errors reported, not the number of
6406 * tests/glr-regression.at (Duplicated user destructor for lookahead):
6407 Mark it as expected to fail.
6408 Cast result of malloc; problem reported by twlevo@xs4all.nl.
6409 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
6410 Don't start user-code symbols with "yy", to avoid name space problems.
6412 2005-09-19 Akim Demaille <akim@epita.fr>
6414 Remove the traits, failed experiment.
6415 It never proved useful, and anyway because of the current
6416 definition, it was not possible to have several specialization of
6417 this traits, making it useless.
6418 * data/lalr1.cc (yy:traits): Remove.
6419 Inline its definitions in the parser class.
6421 2005-09-19 Akim Demaille <akim@epita.fr>
6423 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at
6424 least Mac OSX with a /usr/local install of gettext.
6426 2005-09-19 Akim Demaille <akim@epita.fr>
6428 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
6429 and yytoken for similarity with the other skeletons.
6431 2005-09-19 Akim Demaille <akim@epita.fr>
6433 * NEWS, configure.ac: update version number to 2.1a.
6435 2005-09-16 Paul Eggert <eggert@cs.ucla.edu>
6437 * NEWS: Version 2.1.

6441 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
6443 * src/output.c (prepare): Likewise.
6444 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
6445 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
6446 is not defined. This is an awful hack, but it's enough for now.
6447 All callers changed.
6448 * tests/glr-regression-at (make_value): Args are const pointers now,
6449 to avoid GCC warning.
6450 (Duplicated user destructor for lookahead): New test. Currently
6451 skipped. It fails on my host but I'm not sure it'll always fail.
6453 2005-09-16 Akim Demaille <akim@epita.fr>
6455 * src/symtab.h (struct symbol): Declare the printer and destructor
6456 as const, to avoid accidental calls to free.
6457 (symbol_destructor_set, symbol_printer_set): Adjust.
6458 * src/symtab.c: Adjust.
6460 2005-09-16 Akim Demaille <akim@epita.fr>
6462 * data/c.m4 (b4_token_enums): New.
6463 (b4_token_defines): Rename as...
6464 (b4_token_enums_defines): this.
6465 (b4_token_defines): New, output only the #defines.
6466 * data/yacc.c, data/glr.c: Adjust.
6467 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
6468 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
6471 2005-09-16 Akim Demaille <akim@epita.fr>
6473 * data/lalr1.cc (yylex_): Remove, inline its code.
6474 (yyreport_syntax_error_): Remove, replaced by...
6475 (yysyntax_error_): this which returns a string and leaves to the
6476 caller the call to the users' error function.
6477 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
6478 Move from members of the parser object...
6479 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
6480 to local variables of the parse function.
6482 2005-09-16 Akim Demaille <akim@epita.fr>
6484 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
6485 since it's in Bison's name space.
6487 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
6489 * data/glr.c (yyresolveValue): Add default case to pacify
6490 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
6492 * NEWS: Document when yyparse started to return 2.
6493 * doc/bison.texinfo (Parser Function): Document when yyparse
6496 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
6497 (b4_filename_type): Renamed back from b4_file_name_type. All uses
6499 (class position): file_name -> filename (reverting). All uses changed.
6501 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
6503 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
6504 do anything if $@ exists. This reverts part of the 2005-07-07
6507 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
6509 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
6510 contains obsolete information and isn't worth distributing as a
6511 separate file anyway.
6512 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
6513 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
6514 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
6515 (yyparse): Abort if user code uses longjmp to throw an unexpected
6518 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
6520 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
6521 Suggested by twlevo@xs4all.nl.
6523 * data/glr.c (YYCHK1): Do not assume YYE is in range.
6524 This avoids a diagnostic from gcc -Wswitch-enum.
6525 Problem reported by twlevo@xs4all.nl.
6527 * doc/bison.texinfo: Don't use "filename", as per GNU coding
6528 standards. Use "file name" or "file" or "name", depending on
6530 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
6531 not to hack/foo.tab.c.
6532 (Calc++ Top Level): 2nd arg of main is not const.
6533 * data/glr.c: b4_filename -> b4_file_name.
6534 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
6536 (class position): filename -> file_name. All uses changed.

6545 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
6547 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
6548 to accommodate latest gnulib.
6550 * tests/glr-regression.at (Duplicate representation of merged trees):
6551 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
6553 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
6556 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6558 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
6559 All uses changed. Invoke user destructor after an error during a
6560 split parse (trivial change from Joel E. Denny).
6562 * tests/glr-regression.at
6563 (User destructor after an error during a split parse): New test case.
6564 Problem reported by Joel E. Denny in:
6565 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
6567 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6569 * README-cvs: Give URLs for recommended tools.
6570 Mention Gzip version problem, and bootstrapping issues.
6571 Remove troubleshooting section, as it's somewhat obsolete.
6573 * bootstrap (no_cache): New var, to accommodate different wget
6574 variants. Use it instead of '-C off'. Problem reported by
6577 * data/glr.c (yydestroyStackItem): New function.
6578 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
6579 debugging information. Problem reported by Joel E. Denny.
6581 2005-08-25 Akim Demaille <akim@epita.fr>
6583 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
6585 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

6588 Don't invoke destructor on unresolved entries.
6589 * tests/glr-regression.at
6590 (User destructor for unresolved GLR semantic value): New test case.
6591 Problem reported by Joel E. Denny in:
6592 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
6594 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
6596 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
6598 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
6599 lib-prefix.m4, po.m4.
6601 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
6602 in yydestruct diagnostic, since it might not be an error.
6603 Problem reported by Joel Denny near end of
6604 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6605 * data/lalr1.cc (yyerturn): Likewise.
6606 * data/yacc.c (yyreturn): Likewise.
6607 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
6609 * src/files.c: Remove obsolete FIXME comment.
6611 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
6612 with the other templates, and to fix bogus run-on messages such
6613 as the one reported at the end of
6614 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6615 All callers changed to avoid the newline.
6616 (yyprocessOneStack): Output two lines rather than one, to accommodate
6617 the above change. This changes the debug output format slightly.
6619 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
6620 reported by Joel E. Denny in
6621 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
6623 * tests/glr-regression.at (Duplicate representation of merged trees):
6624 New test, from Joel E. Denny in:
6625 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
6626 * THANKS: Add Joel E. Denny.
6628 * configure.ac (AC_INIT): Bump to 2.0c.
6630 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
6632 * NEWS: Version 2.0b.
6634 * Makefile.am (SUBDIRS): Put examples before tests, so that
6635 "make check" doesn't finish with "All 1 tests passed".
6637 * tests/regression.at (Token definitions): Don't rely on
6638 AT_PARSER_CHECK for data that contains backslashes. It currently
6639 uses 'echo', and 'echo' isn't portable if its argument contains
6640 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
6641 that the byte '\0xff' is not printable in the C locale; it is,
6642 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
6643 not printable, so use '\0x81' to test.
6645 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
6646 version of GCC, since the macro is used with non-GCC compilers.
6648 Fix core dump reported by Pablo De Napoli in
6649 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
6650 * tests/regression.at (Invalid inputs with {}): New test.
6651 * src/parse-gram.y (token_name): Translate type before using
6654 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
6655 the user's name space. All uses changed to __attribute__
6657 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
6658 Add __attribute__ ((__noreturn__)).
6660 * etc/clcommit: Remove. We weren't using it, and it failed
6661 "make maintainer-distcheck".
6662 * Makefile.maint: Merge from coreutils.
6663 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
6664 (syntax-check-rules): Change list of rules as described below.
6665 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

6673 (makefile-check, po-check, author_mark_check):
6674 (makefile_path_separator_check, copyright-check):
6675 Use grep -n, to make it easier to find violations.
6676 Use CVS_LIST and CVS_LIST_EXCEPT.
6677 (header_regexp, h_re): Remove.
6679 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
6680 (my-distcheck): Use more-modern GCC flags.
6681 (signatures, %.asc): Remove.
6682 (rel-files, announcement): Remove signatures.
6683 Restore old updating code, even though we don't use it, so
6684 that we're the same as coreutils.
6685 (alpha, beta, major): Depend on news-date-check.
6686 Make the upload commands.
6688 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
6689 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
6690 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
6691 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

6695 * tests/sets.at: Likewise.
6697 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
6698 we comment out the Autoconf version number.
6699 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
6700 it's error-prone and "make maintainer-distcheck" rejects it.
6702 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
6703 Indent calls to "error" to pacify "make maintainer-distcheck",
6704 when the calls are not intended to be translated.
6705 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
6707 * src/Makefile.am (DEFS): Use +=, to pacify
6708 "make maintainer-distcheck".
6709 (bison_SOURCES): Add scan-skel.h.
6710 (sc_tight_scope): New rule, from coreutils.
6712 * src/files.c (src_extension, header_extension):
6713 Now static, not extern.
6714 * src/getargs.c (short_options): Likewise.
6715 * src/muscle_tab.c (muscle_table): Likewise.
6716 * src/parse-gram.y (current_class, current_type, current_prec):
6718 * src/reader.c (grammar_end, previous_rule_end): Likewise.
6719 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
6720 * src/main.c (main): Cast bindtextdomain and textdomain calls to
6721 void, to avoid warning when NLS is disabled.
6722 * src/output.c: Include scan-skel.h.
6723 (scan_skel): Remove decl, since scan-skel.h does this.
6725 Indent calls to "error" to pacify "make maintainer-distcheck".
6726 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
6727 * src/reader.h (gram_end, gram_lineno): New decls to pacify
6728 "make maintainer-distcheck".
6729 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
6730 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
6731 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
6732 (skel_lex_destroy, scan_skel): Move these decls to...
6733 * src/scan-skel.h: New file.
6734 * src/uniqstr.c (uniqstr_assert):
6735 Indent calls to "error" to pacify "make maintainer-distcheck".
6737 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
6740 * tests/torture.at: Revamp to avoid misuse of atoi that
6741 "make maintainer-distcheck" complained about.
6743 * examples/extexi (message): Don't print a message more than once,
6744 and omit line-number decoration that makes Emacs compile think
6745 that informative messages are worth worrying about.
6747 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
6749 * configure.ac: Update version number.
6751 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
6753 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
6754 autogenerated by the maintainer.
6755 * examples/calc++/.cvsignore: Add *.yy.
6757 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
6758 * lib/bitset_stats.c (bitset_stats_init): Likewise.
6759 * lib/bitsetv.c (bitsetv_alloc): Likewise.
6761 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
6763 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
6764 from maintainer-distcheck about casting the argument of 'free'.
6766 * NEWS: Mention recent yytname changes.
6767 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
6769 * bootstrap: For translations that have not yet been upgraded to
6770 the new runtime-po domain, prime the pump by extracting the
6771 relevant strings from the obsolete translations. This code can be
6772 removed once the bison-runtime domain has been translated by each
6775 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
6776 now that token names are already quoted.
6778 Fix problem reported by Anthony Heading.
6779 * data/glr.c (YYTOKEN_TABLE): New macro.
6780 (yytname): Define if YYTOKEN_TABLE.
6781 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
6782 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
6783 (YYERROR_VERBOSE): Define the same way the other skeletons do.
6784 * src/output.c (prepare_symbols): Output token_table_flag.
6786 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
6788 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
6789 again if the first call fails.
6791 * data/glr.c (yytnamerr): New function.
6792 (yyreportSyntaxError): Use it to dequote most string literals.
6793 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
6794 with other skeletons. All uses changed.
6795 (yytnameerr_): New function.
6796 (yyreport_syntax_error): Use it to dequote most string literals.
6797 * data/yacc.c (yytnamerr): New function.
6798 (yyerrlab): Use it to decode most string literals.
6799 * doc/bison.texinfo (Decl Summary, Calling Convention):
6800 Clarify quoting convention of yytname.
6801 * src/output.c (prepare_symbols): Quote all names. This undoes
6802 the 2005-04-17 change, which is now accomplished (mostly) via
6803 changes in the parsers as described above.
6804 * tests/regression.at (Token definitions, Web2c Actions):
6805 Undo most 2005-04-17 change here, too.
6807 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
6809 Fix more problems reported by twlevo@xs4all.nl.
6810 * tests/cxx-type.at: Don't pipe output of ./types through sed to
6811 remove trailing spaces. This loses the exit status of ./types,
6812 and isn't needed since ./types shouldn't be emitting trailing
6814 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
6815 as the stack isn't valid in that case.
6817 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6818 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6819 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6820 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
6822 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
6823 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
6824 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
6827 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
6828 overly-picky compilers that reject 'char *foo = "bar";'.
6830 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
6831 to FILE * parameter, not to stderr. This fixes a typo introduced
6832 in the 2005-07-12 change.
6834 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
6835 warnings from GCC 4.
6837 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
6838 (yyglrShiftDefer, yysplitStack):
6839 Remove unused parameters b4_pure_formals. All uses changed.
6840 (yyglrShift): Remove unused parameters b4_user_formals.
6842 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
6844 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
6846 Destructor cleanups and regularization among the three skeletons.
6847 * NEWS: Document the behavior changes.
6848 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
6849 stack before failing, as the cleanup code will do it for us now.
6850 * data/lalr1.cc (yyerrlab): Likewise.
6851 * data/glr.c (yyparse): Pop everything off the stack before
6852 freeing it, so that destructors get called properly.
6853 * data/lalr1.cc (yyreturn): Likewise.
6854 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
6855 This is more consistent.
6856 * doc/bison.texinfo (Destructor Decl): Mention more reasons
6857 why destructors might be called. 1.875 -> 2.1.
6858 (Destructor Decl, Decl Summary, Table of Symbols):
6859 Some English-language cleanups for %destructor.
6860 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6861 Add output line for destructor of start symbol.
6862 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
6863 because of that same extra output line.
6865 * NEWS: Document minor wording changes in diagnostics of
6866 Bison-generated parsers.
6867 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
6868 Remove unused formals. All uses changed.
6869 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
6870 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
6871 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
6872 Rename yyoverflowab to yyexhaustedlab.
6873 When memory exhaustion occurs during syntax-error reporting,
6874 report it separately rather than in a single diagnostic; this
6876 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
6877 (Memory Exhausted): Renamed from Parser Stack Overflow.
6878 Revamp wording slightly to prefer "memory exhaustion".
6879 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
6881 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
6883 Add i18n support to the GLR skeleton. Partially fix the C++
6884 skeleton; a C++ expert needs to finish this. Remove debugging
6885 msgids; there's little point to having them translated, since they
6886 can be understood only by someone who can read the
6887 (English-language) source code.
6889 Generate runtime-po/bison-runtime.pot automatically, so that we
6890 don't have to worry about garbage getting in that file. We'll
6891 make sure after the next official release that old msgids don't
6893 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
6895 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
6897 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
6898 Fix typos in explanations of the runtime file.
6899 * bootstrap: Change gettext keyword from YYI18N to YY_.
6900 Use standard Makefile.in.in in runtime-po, since we'll arrange
6901 for backward-compatible bison-runtime.po files in a different way.
6902 * data/glr.c (YY_): New macro, from yacc.c.
6903 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
6904 Translate messages intended for users.
6905 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
6906 the wording in the other skeletons. We don't know that the memory
6908 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
6909 Use same method that yacc.c uses.
6910 Don't translate debugging messages.
6911 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
6912 it doesn't work (yet), and requires C++ expertise to fix.
6913 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
6914 Move defn to a more logical place, to be consistent with other
6916 Don't translate debugging messages.
6917 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
6918 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
6919 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
6920 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
6922 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
6923 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
6925 * tests/glr-regression.at (Badly Collapsed GLR States):
6927 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6928 yylex should return 0 at EOF rather than aborting.
6930 Improve tests for stack overflow in GLR parser.
6931 Problem reported by twlevo@xs4all.nl.
6932 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
6934 (yyStackOverflow): Just longjmp, but with value 2 so that caller
6935 can handle the problem.
6936 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
6937 (yyparse): New local variable yyresult to record the result.
6938 Use result of setjmp to set it, rather than storing itinto
6940 (yyDone): Remove label.
6941 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
6942 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
6943 if YYABORT is used).
6944 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
6945 yyparse status; put status > 1 into diagnostic.
6946 Check that status==2 works.
6947 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
6948 Use exit status 3 for failure to open (which shouldn't happen).
6950 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
6952 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
6953 1 on syntax error; just let yyparse do its thing.
6954 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
6955 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
6956 (Exploding the Stack Size with Alloca):
6957 (Exploding the Stack Size with Malloc):
6958 Expect exit status 2, not 1, since the parser is supposed to blow
6959 its stack. Problem reported by twlevo@xs4all.nl.
6961 * data/glr.c (yyparse): Don't assume that the initial calls
6962 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
6963 Print a stack-overflow message and fail instead.
6964 Initialize the line-number information before creating the stack,
6965 so that the stack-overflow message can report line zero safely.
6967 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
6969 Fix problems reported by twlevo@xs4all.nl.
6970 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
6971 (yyuserMerge): Provide a default case if b4_mergers is empty.
6972 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
6973 * tests/glr-regression.at
6974 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6975 Add casts to pacify C++ compilers.
6976 * tests/glr-regression.at (Improper merging of GLR delayed action
6977 sets): Declare yylex before using it.
6978 * tests/Makefile.am (maintainer-check-g++): Fix a stray
6979 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
6980 test for valgrind; valgrind is independent of g++.
6981 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
6982 for compatibility with POSIX 1003.1-2001 (if running coreutils).
6983 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
6984 Use a destructor, so that we can expand the stack. Change
6985 YYSTYPE to char * so that we can free it. Cast result of malloc.
6987 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
6989 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
6990 a valgrind failure. Problem reported by twlevo@xs4all.nl.
6992 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
6994 * PACKAGING: New file, suggested by Bruno Haible and taken from
6995 similar wording in gettext's PACKAGING file.
6996 * NEWS: Mention PACKAGING.
6997 * Makefile.am (EXTRA_DIST): Add PACKAGING.
6999 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
7001 * NEWS: Document recent i18n improvements.
7002 * bootstrap: Get runtime translations into runtime-po.
7003 Create runtime-po files automatically, if possible.
7004 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
7005 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
7006 does not infringe on the user's name space.
7007 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
7008 * doc/bison.texinfo (Internationalization): Revamp the English
7009 and Texinfo syntax a bit, to try to make it clearer.
7010 (Bison Options, Option Cross Key): Mention --print-localedir.
7011 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
7012 YYENABLE_NLS. Quote a bit more.
7013 * runtime-po/.cvsignore: New file.
7014 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
7015 * runtime-po/Rules-quot: Remove; now created by bootstrap.
7016 * runtime-po/quot.sed: Likewise.
7017 * runtime-po/boldquot.sed: Likewise.
7018 * runtime-po/en@quot.header: Likewise.
7019 * runtime-po/en@boldquot.header: Likewise.
7020 * runtime-po/insert-header.sin: Likewise.
7021 * runtime-po/remove-potcdate.sin: Likewise.
7022 * runtime-po/Makevars: Likewise.
7023 * runtime-po/LINGUAS: Likewise.
7024 * runtime-po/de.po: Likewise; we will rely on the translation project
7025 to maintain this, so "bootstrap" should get it.
7026 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
7028 * src/main.c (main): Bind the bison-runtime domain, too.
7030 2005-07-12 Bruno Haible <bruno@clisp.org>
7032 * data/yacc.c: Include <libintl.h> when NLS is enabled.
7033 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
7034 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
7035 * runtime-po: New directory.
7036 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
7037 $(DOMAIN).pot-update rule, so that old messages are never dropped.
7038 * runtime-po/Rules-quot: New file, copied from po/.
7039 * runtime-po/quot.sed: Likewise.
7040 * runtime-po/boldquot.sed: Likewise.
7041 * runtime-po/en@quot.header: Likewise.
7042 * runtime-po/en@boldquot.header: Likewise.
7043 * runtime-po/insert-header.sin: Likewise.
7044 * runtime-po/remove-potcdate.sin: Likewise.
7045 * runtime-po/Makevars: New file.
7046 * runtime-po/POTFILES.in: New file.
7047 * runtime-po/LINGUAS: New file.
7048 * runtime-po/bison-runtime.pot: New file.
7049 * runtime-po/de.po: New file.
7050 * m4/bison.m4: New file.
7051 * Makefile.am (SUBDIRS): Add runtime-po.
7052 (aclocaldir, aclocal_DATA): New variables.
7053 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
7055 * src/getargs.c (usage): Document --print-localedir option.
7056 (PRINT_LOCALEDIR_OPTION): New enum item.
7057 (long_options): Add --print-localedir option.
7058 (getargs): Handle --print-localedir option.
7059 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
7060 (Internationalization): New section.
7062 2005-07-12 Akim Demaille <akim@epita.fr>
7064 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
7065 for consistency with the rest of the code.
7066 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
7069 2005-07-12 Akim Demaille <akim@epita.fr>
7071 * src/parse-gram.y: Use %printer instead of YYPRINT.
7073 2005-07-12 Akim Demaille <akim@epita.fr>
7075 * src/symtab.h, src/symtab.c (symbol_print): New.
7076 * src/symlist.h, src/symlist.c (symbol_list_print): New.
7077 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
7079 2005-07-12 Akim Demaille <akim@epita.fr>
7081 * data/glr.c (b4_syncline): Fix (swap) the definitions of
7082 b4_at_dollar and b4_dollar_dollar.
7084 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
7086 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
7087 and Pennello's paper.
7089 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
7091 * data/yacc.c (yyparse): Undo previous patch. Instead,
7092 set yylsp[0] and yyvsp[0] only if the initial action
7093 sets yylloc and yylval, respectively.
7095 * data/yacc.c (yyparse): In the initial action, set
7096 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
7097 This avoids the use of undefined variables if the initial
7098 action does not set yylloc and/or yylval.
7100 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7102 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
7103 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
7104 Remove from CVS. These files are automatically generated.
7105 * examples/extexi: Clarify that this file is now part of Bison,
7106 not GNU M4, and that it works with any POSIX-compatible Awk.
7107 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
7108 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
7109 so that we also get calc++-parser.yy. Geneate it.
7110 Use $(AWK), not gawk, since any conforming Awk will do.
7111 Put comment before action, since older 'make' can't handle comment
7113 $(BUILT_SOURCES): List all built sources, not just some of them.
7114 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
7115 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
7116 $($(calc_sources_generated)): Remove unnecessary test for existence
7117 of target. (This had a shell syntax error anyway; a stray "x".)
7118 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
7120 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
7122 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
7123 implied by the other modules.
7125 2005-07-06 Akim Demaille <akim@epita.fr>
7127 Bind examples/calc++ to the package.

7136 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
7138 * data/glr.c (yyFail): Drastically simplify; since the format argument
7139 never had any % directives, we can simply pass it to yyerror.
7140 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
7141 be modified later, as that is the usual style in glr.c.
7142 Problems reported by Paul Hilfinger.
7144 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
7145 and size overflow errors.
7146 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
7147 in case the user prolog sets feature-test macros like _GNU_SOURCE.
7148 (YYSIZEMAX): New macro.
7149 (yystpcpy): New function, taken from yacc.c.
7150 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
7151 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
7152 so that we don't have to maintain their signatures.
7153 (yyFail): Check for buffer overflow, by using vsnprintf rather
7154 than vsprintf. Allocate a bigger buffer if possible.
7155 Report an error if buffer allocation fails.
7156 (yyStackOverflow): New function.
7157 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
7158 the initialization was successful. It might fail if storage was
7160 (yyexpandGLRStack): Add more checks for storage allocation failure.
7161 Use yyStackOverflow to report failures.
7162 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
7163 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
7164 Don't assume stack number fits in int.
7165 (yysplitStack): Check for storage allocation failure.
7166 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
7167 can print diagnostics on storage allocation failure. All callers
7169 (yyresolveValue): Use yybool for boolean.
7170 (yyreportSyntaxError): Check for size-calculation overflow.
7171 This code is taken from yacc.c.
7172 (yyparse): Check for storage allocation errors when allocating
7175 2005-07-05 Akim Demaille <akim@epita.fr>
7177 Extract calc++ from the documentation.
7178 * doc/bison.texinfo (Calc++): Add the extraction marks.
7179 * examples/extexi: New, from the aborted GNU Programming 2E.
7180 Separate the different paragraph of a file with empty lines.
7181 * examples/Makefile: Use it to extract the whole calc++ example.
7183 2005-06-24 Akim Demaille <akim@epita.fr>
7185 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
7188 2005-06-22 Akim Demaille <akim@epita.fr>
7190 * doc/bison.texinfo (C++ Language Interface): First stab.
7191 (C++ Parsers): Remove.
7193 2005-06-22 Akim Demaille <akim@epita.fr>
7195 * data/lalr1.cc (yylex_): Honor %lex-param.
7197 2005-06-22 Akim Demaille <akim@epita.fr>
7199 Start a set of simple examples.
7200 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
7201 * examples/calc++/calc++-driver.hh,
7202 * examples/calc++/calc++-parser.yy,
7203 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
7204 * examples/calc++/compile, examples/calc++/test: New.
7206 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
7208 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
7209 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
7210 which stems from the 2005-05-27 patch.
7212 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7214 * data/glr.c: Modify treatment of unused parameters to permit use
7215 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
7217 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
7219 Fix infringement on user name space reported by Janos Zoltan Szabo.
7220 * data/yacc.c (yyparse): strlen -> yystrlen.
7222 2005-05-30 Akim Demaille <akim@epita.fr>
7224 * data/lalr1.cc (_): New.
7225 Translate the various messages.
7227 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7229 Fix infringement on user name space reported by Bruno Haible.
7230 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
7231 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
7232 the user's name space.
7233 (alloca): Include <stdlib.h> to get it, if it's not built in.
7234 (YYMALLOC, YYFREE): Define only if needed.
7235 (malloc, free): Declare, but only if needed, as this infringes on
7236 the user name space.
7238 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7240 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
7241 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
7243 * lib/ebitset.c (min, max): Undef before defining.
7244 * lib/vbitset.c (min, max): Likewise.
7245 * lib/subpipe.c (create_subpipe): Save local variables in case
7246 vfork clobbers them.
7248 2005-05-24 Bruno Haible <bruno@clisp.org>
7250 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
7251 error message syntax used by gcc-4.0.
7253 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
7255 * README: Mention m4 1.4.3. Remove obsolete advice about
7256 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
7258 * bootstrap: Remove workaround for problem I encountered with
7259 gettext 0.14.1; it seems to be fixed now.
7261 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
7263 * NEWS: Version 2.0a.
7265 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
7266 the previous change.
7268 Various maintainer cleanups.
7269 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
7270 conftest*, for benefit of CVS commands run at the same time as
7271 "configure". Add build-aux, since "bootstrap" now creates it and
7273 * Makefile.cfg (move_if_change): Remove.
7274 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
7275 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
7276 (po_repo, do-po-update, po-update, wget_files, get-targets):
7277 (config.guess-url_prefix, config.sub-url_prefix):
7278 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
7279 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
7280 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
7282 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
7283 this is now the recommended name.
7284 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
7285 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
7286 ylwrap. These files now go into build-aux.
7287 * config/move-if-change: Remove.
7288 * config/prev-version.txt: Bump from 1.75 to 2.0.
7290 * bootstrap: Add stdio-safer, unistd-safer modules.
7291 Remove m4/glibc2.m4 (introduced by latest gnulib, but
7293 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
7294 fopen-safer.c, stdio-safer.h, unistd-safer.h.
7295 * lib/subpipe.c: Include "unistd-safer.h".
7296 (create_subpipe): Make sure all the newly-created
7297 file descriptors are > 2, so that diagnostics don't
7298 get sent down them (which might cause Bison to hang, in theory).
7299 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
7300 * src/files.c (xfopen): Use fopen_safer, not fopen.
7302 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
7303 yesterday's yacc.c fix.
7305 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
7307 * data/glr.c, data/lalr1.cc: Update copyright date.
7309 Fix a destructor bug reported by Wolfgang Spraul in
7310 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
7311 * data/yacc.c (yyabortlab): Don't call destructor, and
7312 don't set yychar to EMPTY.
7313 (yyoverflowlab): Don't call destructor.
7314 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
7315 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
7316 since we no longer output the message "discarding lookahead token
7319 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7321 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
7322 fix a small glitch in debugging output.
7323 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
7324 after YY_SYMBOL_PRINT where needed.
7326 (struct yyGLRState): Add some comments.
7327 (struct yySemanticOption): Add some comments.
7328 (union yyGLRStackItem): Add comment.
7330 (yymergeOptionSets): Correct this to properly perform the union,
7331 avoiding infinite reported by Michael Rosien.
7334 * tests/glr-regression.at: Add test for GLR merging error reported

7373 Update FSF postal mail address.
7375 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
7377 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
7378 Problem reported by Ralf Menzel.
7380 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7382 * tests/actions.at: Test that stack overflow invokes destructors.
7383 From Marcus Holland-Moritz.
7384 * data/yacc.c (yyerrlab): Move the code that destroys the stack
7386 (yyreturn): to here. That way, destructors are called properly
7387 even if the stack overflows, or the user calls YYACCEPT or
7388 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
7389 (yyoverflowlab): Destroy the lookahead.
7391 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
7393 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
7395 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
7397 * NEWS: Bison-generated C parsers no longer quote literal strings
7398 associated with tokens.
7399 * src/output.c (prepare_symbols): Don't escape strings,
7400 since users don't want to see C escapes.
7401 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
7403 * tests/input.at (Torturing the Scanner): Likewise.
7404 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
7406 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
7408 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
7409 the data size is known to be too small and we can't increase it.
7410 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
7412 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
7414 * src/parse-gram.y: Include quotearg.h.
7415 (string_as_id): Quote $1 before using it as a key, since the
7416 lexer no longer quotes it for us.
7417 (string_content): Don't strip quotes, since lexer no longer
7419 * src/scan-gram.l: Include quotearg.h.
7421 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
7422 a key, since the rest of the lexer doesn't quote it.
7423 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
7424 * tests/regression.at (Token definitions): Check for backslashes
7427 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
7428 (YYSIZE_T): Define to unsigned long int when using an older compiler.
7429 (yyparse): Revamp code to generate long syntax error message, to
7430 make it easier to translate, and to avoid problems with arithmetic
7431 overflow. Change "virtual memory" to "memory" in diagnostic, since
7432 we don't know whether the memory is virtual.
7434 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7436 * NEWS: Bison-generated C parsers now use the _ macro to
7438 * data/yacc.c (_) [!defined _]: New macro.
7439 All English strings wrapped inside this macro.
7440 * doc/bison.texinfo (Bison Parser): Document _.
7441 * po/POTFILES.in: Include src/parse-gram.c, since it now
7442 includes translateable strings that parse-gram.y doesn't.
7444 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
7446 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
7447 reverting the 2004-10-11 change to this function.
7448 (symbol_check_alias_consistency): Don't call symbol_type_set
7449 if the type name is already correct.
7450 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
7452 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
7454 * tests/regression.at (Token definitions): Don't use a token named
7455 c, as that generates a "#define c ..." that runs afoul of buggy
7456 stdlib.h that uses the identifier c as a member of struct
7457 drand48_data. Problem reported by Horst Wente.
7459 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
7461 * bootstrap: Change translation URL from
7462 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
7463 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
7464 redirection glitches. Problem reported by twlevo@xs4all.nl.
7466 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
7468 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
7469 after operands; POSIX says this isn't portable for the c99 command.
7471 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
7473 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
7474 immediately if a data overrun has occurred; this may help us track
7475 down what may be a spurious failure on MacOS.
7477 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
7479 Respond to problems reported by twlevo@xs4all.nl.
7481 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
7483 * src/vcg.h: Comment fix.
7484 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
7485 (G_CMAX): Change to -1 instead of INT_MAX.
7487 * data/yacc.c (yyparse): Omit spaces before #line.
7489 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
7491 * src/tables.c (state_number_to_vector_number): Put it inside an
7492 "#if 0", since it's not currently used. Problem reported by
7495 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
7497 * src/output.c (escaped_output): Renamed from
7498 escaped_file_name_output, since we now use it for symbol tags as
7499 well. All uses changed.
7500 (symbol_destructors_output, symbol_printers_output):
7501 Escape symbol tags too.
7502 Problem reported by Matyas Forstner in
7503 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
7505 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
7507 * src/output.c (user_actions_output, token_definitions_output,
7508 symbol_destructors_output, symbol_printers_output): Likewise.
7509 * src/reader.c (prologue_augment): Likewise.
7510 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
7512 * src/vcg.c (output_edge): Don't quote linestyle arg.
7513 Problem reported by twlevo@xs4all.nl.
7515 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
7517 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
7518 example, reported by Derek M Jones. Also, make the example even
7519 more outrageous, to better illustrate how bad the problem is.
7521 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
7523 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
7524 putsym. Typo reported by Sebastian Piping.
7526 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7528 * doc/bison.texinfo (Language and Grammar): some -> same
7529 (Epilogue): int he -> in the
7530 Typos reported by Sebastian Piping via Justin Pence.
7532 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7534 * tests/glr-regression.at (Improper handling of embedded actions
7535 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
7536 embedded actions and $-N in GLR parsers", work around an Autoconf bug
7537 with dollar signs in test names.
7538 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
7539 for a similar reason.
7541 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7543 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
7544 wants to redefine G_VIEW.
7546 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
7548 * src/vcg.c (get_view_str): Remove case for normal_view.
7549 Problem reported by twlevo@xs4all.nl.
7551 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
7553 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
7554 Problem reported by twlevo@xs4all.nl.
7556 * doc/bison.texinfo: Change @dircategory from "GNU programming
7557 tools" to "Software development". Requested by Richard Stallman
7560 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
7562 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
7563 Problem reported by twlevo@xs4all.nl.
7565 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
7567 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
7568 keyword; it's not needed with modern compilers, and it doesn't
7569 affect correctness with older compilers. Suggested by
7572 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
7574 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
7575 gcc -Wswitch-default.
7576 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
7577 * data/yacc.c (yyparse): Likewise.
7579 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
7581 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
7582 already. Let config.h define any nonstandard values.
7584 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
7586 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
7587 for the benefit of slower hosts. Problem reported by
7590 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
7592 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
7593 being defined and not used.
7594 * data/lalr1.cc (yyparse): Likewise.
7595 Use "if (false)" rather than "if (0)".
7597 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
7599 * TODO: Mention that we should allow NUL bytes in tokens.
7601 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
7603 * src/scan-skel.l (<<EOF>>): Don't close standard output.
7604 Problem reported by Hans Aberg.
7606 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
7608 * src/getargs.c (version): Happy new year; update overall
7609 program copyright date from 2004 to 2005.
7611 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
7612 Problem reported by Hans Aberg.
7613 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
7614 (Output file names.): Add a test for the case when standard output
7617 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
7619 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
7620 to fix an oversight in the Bison 2.0 manual.
7622 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
7624 * NEWS: Version 2.0. Reformat the existing news items since
7625 1.875, so that related items are grouped together.
7626 * configure.ac (AC_INIT): Bump version to 2.0.
7627 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
7629 * tests/torture.at (Exploding the Stack Size with Alloca): Set
7630 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
7631 otherwise, we're not testing alloca. Unfortunately there's no
7632 simple way to consult HAVE_ALLOCA here.
7634 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
7637 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
7638 hand. This avoids a warning about comparing int to size_t when
7639 GCC warnings are enabled.
7641 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
7643 * NEWS: Bison-generated parsers no longer default to using the
7644 alloca function (when available) to extend the parser stack, due
7645 to widespread problems in unchecked stack-overflow detection.
7646 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
7647 responsibility to set it to a positive value. This lets the user
7648 specify a value that is not a preprocessor constant.
7649 * data/yacc.c (YYMAXDEPTH): Likewise.
7650 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
7651 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
7652 to be a compile-time constant. However, explain the constraints on it.
7653 Also, explain the constraints on YYINITDEPTH.
7654 (Table of Symbols): Explain that alloca is no longer the default.
7655 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
7658 * doc/bison.texinfo (Location Default Action): Mention that n must
7659 be zero when k is zero. Suggested by Frank Heckenbach.
7661 2004-12-22 Akim Demaille <akim@epita.fr>
7663 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
7664 (parser::state_type, parser::semantic_type, parser::location_type):
7665 Private, not public.
7666 (parser::parse): Return ints, not bool.
7667 Returning a bool introduces a problem: 0 corresponds to false, and
7668 it seems weird to return false on success. Returning true changes
7669 the conventions for yyparse.
7670 Alternatively we could return void and send an exception.
7671 There is no clear consensus (yet?).
7672 (state_stack, semantic_stack, location_stack): Rename as...
7673 (state_stack_type, semantic_stack_type, location_stack_type): these.
7674 Private, not public.
7675 * tests/c++.at: New.
7676 * tests/testsuite.at, tests/Makefile.am: Adjust.
7678 2004-12-21 Akim Demaille <akim@epita.fr>
7680 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
7682 2004-12-21 Akim Demaille <akim@epita.fr>
7684 Don't impose std::string for filenames.
7686 * data/lalr1.cc (b4_filename_type): New.
7687 (position::filename): Use it.
7688 (parser.hh): Move the inclusion of stack.hh and location.hh below
7689 the user code, so that needed headers for the filename type can be
7691 Forward declare them before the user code.
7692 * tests/Makefile.am (check-local, installcheck-local): Pass
7693 TESTSUITEFLAGS to the TESTSUITE.
7695 2004-12-20 Akim Demaille <akim@epita.fr>
7697 Use more STL like names: my_class instead of MyClass.
7699 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
7700 (SemanticStack, SemanticType, StateStack, StateType)
7701 (TokenNumberType, Stack, Slice, Traits, Parser::location)
7702 (Parser::value): Rename as...
7703 (location_stack, location_type, rhs_number_type, semantic_stack)
7704 (semantic_type, state_stack, state_type, token_number_type, stack)
7705 (slice, traits, parser::yylloc, parser::yylval): these.
7707 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
7709 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
7711 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
7712 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
7714 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
7716 Remove uses of 'short int' and 'unsigned short int'. This raises
7717 some arbitrary limits. It uses more memory but nowadays that's
7718 not much of an issue.
7720 This change does not affect the generated parsers; that's a different
7721 task, as some users will want to conserve memory there.
7723 Ideally we should use size_t to represent all object counts, and
7724 something like ptrdiff_t to represent signed differences of object
7725 counts; but that will require more code-cleanup than I have the
7726 time to do right now.
7728 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
7729 Use size_t, not int or short int, to count objects.

7749 2004-12-17 Akim Demaille <akim@epita.fr>
7751 * data/lalr1.cc: Extensive Doxygenation.
7752 (error_): Rename as...
7753 (error): this, since it is visible to the user.
7755 (Parser::message): Now an automatic variable from...
7756 (Parser::yyreport_syntax_error_): here.
7757 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to

7764 Parenthesize rhs to avoid obscure problems with mistakes like
7765 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
7766 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,

7782 2004-12-16 Akim Demaille <akim@epita.fr>
7784 Use #define to handle the %name-prefix.
7786 * data/glr.c, data/yacc.c: Comment changes.
7787 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
7788 so that one can refer to yylex in the parser file, and have it
7789 renamed, as is the case with other skeletons.
7791 2004-12-16 Akim Demaille <akim@epita.fr>

7813 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
7815 Fix some problems reported by twlevo at xs4all.
7816 * src/symtab.c (symbol_new): Report an error if the input grammar
7817 contains too many symbols. This is better than calling abort() later.
7818 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
7819 (struct node, struct graph):
7820 Rename member expand to stretch. All uses changed.

7844 2004-12-15 Akim Demaille <akim@epita.fr>
7846 Simplify the C++ parser constructor.
7848 * data/lalr1.cc (debug_): Rename as...
7849 (yydebug_): so that the parser's internals are always in the yy*
7852 (b4_parse_param_decl): Remove the leading comma as it is now only
7853 called as unique argument list.
7854 (Parser::Parser): Remove the constructor accepting a location and

7859 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
7862 2004-12-15 Akim Demaille <akim@epita.fr>
7864 Remove b4_root related material: failure experiment
7865 (which goal was to allow to derive from a class).
7867 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
7868 definitions and uses.
7870 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
7872 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
7873 not 2, since it's not portable to subtract 1 from the start of an
7874 array. The new item 0 is never set or used. All uses changed.
7876 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
7877 the default definition of YYLLOC_DEFAULT. Problem reported
7878 by Frank Heckenbach.
7880 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
7882 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
7883 the normal case and one for the error case. Just use the
7884 first one uniformly. Problem reported by Frank Heckenbach.
7885 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
7886 use exactly the same macro in both places.
7887 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
7888 so that the normal-case YYRHSLOC works for the error case too.
7890 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
7891 (YYLLOC_DEFAULT): Use the same macro as glr.c.
7892 * doc/bison.texinfo (Location Default Action): Don't claim that
7893 we have an array of locations. Use the same macro for both glr
7894 and lalr parsers. Mention YYRHSLOC. Mention what happens when
7897 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>

7906 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
7908 * src/scan-skel.l: Include "complain.h", for "fatal".
7910 * src/relation.h (relation_print, relation_digraph):
7911 Relation sizes are of type relation_node, not size_t (this is
7912 merely a doc fix, since the two types are equivalent).
7913 (relation_transpose): Relation sizes are of type relation_node,
7915 * src/relation.c: Likewise.
7916 (top, infinity): Now of type relation_node, not int.

7919 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
7920 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
7921 (yyparse): Remove unused local introduced in 2004-10-25 patch.
7923 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
7924 specifying whether the test should be skipped. Use it tp
7925 specify that the [%defines %skeleton "lalr1.cc"] tests currently
7926 fail on some hosts, and should be skipped.
7928 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
7930 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
7931 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
7932 unless otherwise specified below.
7934 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
7935 to allocate kernel_base, kernel_items, kernel_size, since
7936 they needn't be initialized to 0.
7937 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
7938 * src/closure.c (new_closure): Likewise, for itemset.
7939 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

7945 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
7946 * src/relation.c (relation_digraph): Likewise for VERTICES.
7947 (relation_transpose): Likewise for new_R, end_R.
7948 * src/symtab.c (symbols_token_translations_init): Likewise for
7950 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
7951 (token_actions): Likewise for yydefact, actrow, conflrow,
7953 (save_column): Likewise for froms[symno], tos[symno].
7954 (goto_actions): Likewise for state_count.
7955 (pack_table): Likewise for base, pos, check.
7956 (tables_generate): Likewise for width.
7958 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
7959 for initial core. Just have a separate core, so we needn't worry
7960 about whether kernel_size and kernel_base are initialized.
7962 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
7963 kernel_size, kernel_items): Remove unnecessary initialization.
7964 * src/conflicts.c (conflicts): Likewise.
7965 * src/derives.c (derives): Likewise.
7966 * src/muscle_tablc (muscle_insert): Likewise.

7968 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
7969 conflrow, conflict_table, conflict_list, table, check):
7972 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
7973 This is because all callers pass unsigned int.
7974 * src/closure.h (new_closure): Likewise.
7976 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
7977 (build_relations): Initialize includes[i] in all cases.
7978 * src/reader.c (packgram): Always initialize rules[ruleno].prec
7979 and rules[ruleno].precsym. Initialize members in order.
7980 * src/relation.c (relation_transpose): Always initialize new_R[i]
7982 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
7984 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
7985 conflict_list[0] was always 0, but now it isn't initialized.
7987 * src/table.c (table_grow): When conflict_table grew, the grown
7988 area wasn't cleared. Fix this.
7990 * lib/.cvsignore: Add strdup.c, strdup.h.
7991 * m4/.cvsignore: Add strdup.m4.
7993 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
7995 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
7996 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
7997 GOTO_NUMBER_MAXIMUM, since we occasionally compute
7998 ngotos + 1 without checking for overflow.
7999 (build_relations): Use END_NODE, not -1, to denote end of edges.
8000 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
8001 build_relations): Use goto_number, not int, for goto numbers.
8002 * src/tables.c (save_column, default_goto): Likewise.
8004 2004-11-23 Akim Demaille <akim@epita.fr>
8006 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
8007 of #defining from yystype.
8008 Don't typedef yystype, C++ does not need it.
8009 This lets it possible to forward declare it as union.
8011 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
8013 * bootstrap (gnulib_modules): Add extensions.
8014 Problem reported by Jim Meyering.
8016 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
8018 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
8019 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
8020 src/system.h, src/tables.c: XFREE -> free, to accommodate
8021 recent change to gnulib xalloc.h.
8022 Problem reported by Jim Meyering.
8024 2004-11-17 Akim Demaille <akim@epita.fr>
8026 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
8028 2004-11-17 Akim Demaille <akim@epita.fr>,
8029 Alexandre Duret-Lutz <adl@gnu.org>
8031 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
8034 Use it instead of cdebug_.
8035 (Parser::debug_stream, Parser::set_debug_stream): New.
8036 (Parser::symprint_): Define cdebug_ for temporary backward
8038 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
8041 2004-11-17 Akim Demaille <akim@epita.fr>
8043 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
8044 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
8045 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
8046 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

8051 Problem reported by Frank Heckenbach.
8053 2004-10-25 Akim Demaille <akim@epita.fr>
8055 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
8056 Introduce another definition to address simple location arrays.
8057 (yyGLRStack): New member: yyerror_range.
8058 (yyrecoverSyntaxError, yyparse): Update it.
8059 (yyrecoverSyntaxError): Use it when shifting the error token to
8060 have an accurate range, equivalent to the one computed by both
8061 yacc.c and lalr1.cc.
8062 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
8063 that column numbers start at column 0, as per GNU Coding
8064 Standards, the others tests, and the doc.
8065 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
8066 Adjust to the above change (first column is 0).
8067 And adjust the location of the "<error>", now covering the whole
8070 2004-10-22 Akim Demaille <akim@epita.fr>
8071 and Paul Eggert <eggert@cs.ucla.edu>
8073 Remove some arbitrary limits on goto numbers and relations.
8074 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
8075 initial values, since they're never used.
8076 (set_goto_map): ngotos is now unsigned, so test for overflow
8077 by seeing whether it wraps around to zero.
8078 * src/lalr.h (goto_number): Now size_t, not short int.
8079 (GOTO_NUMBER_MAXIMUM): Remove.
8080 * src/relation.c (relation_print, traverse, relation_transpose):
8081 Check for END_NODE rather than looking at sign.
8082 * src/relation.h (END_NODE): New macro.
8083 (relation_node): Now size_t, not short int.
8085 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
8087 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
8088 keyword, not an identifier. Problem reported by Baron Schwartz in
8089 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
8091 2004-10-11 Akim Demaille <akim@epita.fr>
8093 * src/symtab.c (symbol_check_alias_consistency): Also check
8094 type names, destructors, and printers.
8095 Reported by Alexandre Duret-Lutz.
8096 Recode the handling of associativity and precedence in terms
8097 of symbol_precedence_set.
8098 Accept no redeclaration at all, not even equal to the previous
8100 (redeclaration): New.
8101 Use it to factor redeclaration complaints.
8102 (symbol_make_alias): Don't set the type of the alias, let
8103 symbol_check_alias_consistency do it as for other features.
8104 * src/symtab.h (symbol): Add new member prec_location, and
8106 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
8107 * tests/input.at (Incompatible Aliases): New.
8109 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
8111 .cvsignore fixes to accommodate gnulib changes,
8112 and the practice of naming build directories "_build".
8113 * .cvsignore: Add "_*". Sort.
8114 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
8115 * m4/.cvsignore: Add "*_gl.m4".
8117 2004-10-06 Akim Demaille <akim@epita.fr>
8119 * src/parse-gram.y (add_param): Fix the truncation of trailing
8122 2004-10-05 Akim Demaille <akim@epita.fr>
8124 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8125 whether the reducion was empty or not. This leaves room to
8126 improve the use of YYLLOC_DEFAULT in such a case.
8127 lalr1.cc is still experimental, so changing this is acceptable.
8128 And finally, there are probably not many users who changed the
8129 handling of locations in GLR, so changing is admissible too.
8131 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
8132 empty reduction, set @$ to an empty location ending the previously
8134 Adjust uses to make sure the code is triggered on empty
8136 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
8137 expected output: empty reductions have empty locations.
8139 2004-09-29 Akim Demaille <akim@epita.fr>
8141 * data/lalr1.cc: Move towards a more standard C++ coding style
8142 for templates: Class < T > -> Class<T>.
8144 2004-09-29 Akim Demaille <akim@epita.fr>
8146 * data/lalr1.cc: Reinstall the former ctor, for sake of
8147 compatibility, but warn it will be removed.
8148 Move towards a more standard C++ coding style (i.e., type *var ->
8151 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
8153 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
8154 since it's less likely to work if NULs are involved in the future.
8156 2004-09-27 Akim Demaille <akim@epita.fr>
8158 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
8160 2004-09-27 Akim Demaille <akim@epita.fr>
8162 * data/lalr1.cc (b4_parse_param_decl_1): New.
8163 (b4_parse_param_decl): Use it to have different names between attribute
8165 (b4_cc_constructor_call): Likewise.
8167 2004-09-24 Akim Demaille <akim@epita.fr>
8169 * src/parse-gram.y (add_param): Strip the leading and trailing
8170 blanks from a formal argument declaration.
8171 (YY_LOCATION_PRINT): New.
8173 2004-09-24 Akim Demaille <akim@epita.fr>
8175 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
8178 2004-09-24 Akim Demaille <akim@epita.fr>
8180 * doc/bison.texinfo (Table of Symbols): Sort.
8182 2004-09-21 Akim Demaille <akim@epita.fr>
8184 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
8185 the useless parentheses.
8186 Suggested by Paul Eggert.
8188 2004-09-20 Akim Demaille <akim@epita.fr>
8190 Let the initial-action act on the look-ahead, and use it for the
8191 "initial push" (corresponding to an hypothetical beginning-of-file).
8192 And let lalr1.cc honor %initial-action.
8194 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
8196 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
8197 (Parser::Parser): Remove the ctor that used to initialize it.
8198 (Parser::parse): Like in the other skeletons, issue the "starting
8199 parse" message before any action.
8200 Honor %initial-action.
8201 Initialize the stacks with the lookahead.
8202 * data/yacc.c: Let $$ and @$ in %initial-action designate the
8204 Push them in the stacks.
8205 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
8207 2004-09-20 Akim Demaille <akim@epita.fr>
8209 * doc/bison.texinfo (Initial Action Decl): New.
8211 2004-09-20 Akim Demaille <akim@epita.fr>
8213 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
8214 clearer criterion to define it.
8215 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
8216 When reducing on an empty RHS, use the latest stacked location as
8218 yylloc is not always available.
8219 * data/glr.c: Likewise.
8220 Also, honor initial-actions.
8222 2004-09-20 Akim Demaille <akim@epita.fr>
8224 * data/yacc.c (YY_LOCATION_PRINT): New.
8225 Define when we know YYLTYPE's structure, i.e., when the default
8226 YYLLOC_DEFAULT is used.
8227 * data/c.m4 (b4_yysymprint_generate): Use it.
8228 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
8229 value of the result.
8230 (error_start_): Replace with...
8231 (error_range_): this location array.
8232 This allows to replace code relying on the implementation of
8233 locations by portable code.
8234 * data/yacc.c (yylerrsp): Replace with...
8235 (yyerror_range): this.
8236 Every time a token is popped, update yyerror_range[0], to have an
8237 accurate location for the error token.
8238 * data/glr.c (YY_LOCATION_PRINT): New.
8239 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
8240 deference a pointer.
8241 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
8242 report the location in %printers.
8244 * src/scan-skel.l: Instead of abort, report error messages to ease
8245 understanding skeleton scanning failures.
8247 2004-09-16 Akim Demaille <akim@epita.fr>
8249 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
8250 (iterator, const_iterator): these, to be more in the C++ spirit.
8251 Also, return reverse iterators so that when displaying the stack
8252 we display its bottom first.
8253 (Parser::stack_print_, Parser::reduce_print_): Match the messages
8255 We should probably use vector here though.
8257 2004-09-16 Akim Demaille <akim@epita.fr>
8259 Have more complete shift traces.
8261 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
8262 to report Shifts instead of ad hoc YYDPRINTF invocations,
8263 including for the error token.
8264 * data/lalr1.cc (symprint_): Output the location.
8265 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
8266 output the location within the %printer.
8267 Activate GLR tests, at least to make sure they compile properly.
8268 They still don't pass though.
8269 * tests/calc.at: Adjust expect verbose output, since now "Entering
8270 state..." is on a different line than the "Shifting" message.
8272 2004-09-08 Akim Demaille <akim@epita.fr>
8274 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
8275 Bison directive from the Bison file to the invocation of this
8276 macro, so that these directives are passed to
8277 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8278 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8279 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8280 the extra Bison directives instead of the whole series.
8281 Change the grammar so that there are recoverable errors, and
8282 unrecoverable errors. Now we can have the parser give up before
8283 consuming the whole input. As a result we now can observe that
8284 the lookahead is freed when needed.
8285 Change the parser source to parse argv[1] instead of a hard coded
8287 Simplify yylex, and give a value and location to EOF.
8288 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8289 passed directives already coded in the file.
8290 Add some tests to check the location of "error".
8291 For some tests, the C++ parser is correct, and not yacc.c.
8292 For other tests, they provide different, but unsatisfying, values,
8293 so keep the C++ value so that at least one parser is "correct"
8294 according to the test suite.
8295 (Actions after errors): Remove, this is subsumed by the
8296 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
8298 2004-09-06 Akim Demaille <akim@epita.fr>
8300 * data/lalr1.cc: Adjust the indentation of the labels.
8304 2004-09-06 Akim Demaille <akim@epita.fr>
8306 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
8307 argument, an informative message.
8308 Call YY_SYMBOL_PRINT.
8309 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
8310 * data/lalr1.cc (destruct_): Likewise.
8311 In addition, no longer depend on b4_yysymprint_generate and
8312 b4_yydestruct_generate to generate these functions, do it "by
8315 2004-09-03 Akim Demaille <akim@epita.fr>
8317 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
8318 invoked, yydestruct the lookahead.
8319 * tests/calc.at (Calculator $1): Update the expected lengths of
8320 traces: there is an added line for the discarded lookahead.
8321 * doc/bison.texinfo (Destructor Decl): Some rewording.
8322 Define "discarded" symbols.
8324 2004-09-02 Akim Demaille <akim@epita.fr>
8326 * data/lalr1.cc (translate_, destruct_): No reason to be static.
8328 2004-09-02 Akim Demaille <akim@epita.fr>
8330 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
8331 (YYDSYMPRINTF): Rename as...
8332 (YY_SYMBOL_PRINT): this.
8333 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
8335 Use it instead of direct symprint_ calls.
8336 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
8339 2004-09-02 Akim Demaille <akim@epita.fr>
8341 * data/lalr1.cc (b4_yysymprint_generate): New.
8342 (symprint_): New member function, defined when YYDEBUG.
8343 Use it consistently instead of token/nterm debugging output by
8345 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
8346 %printer calls to use cdebug_ when using lalr1.cc.
8348 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
8350 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
8351 with #ifdef YYDEBUG.
8353 2004-08-26 Akim Demaille <akim@epita.fr>
8355 * doc/bison.texinfo (Implementing Loops): Rename as...
8356 (Implementing Gotos/Loops): this.
8358 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
8360 Adjust to latest gnulib.
8361 * bootstrap (gnulib_modules): Add xalloc-die.
8362 Set LC_ALL=C so that file names sort consistently.
8363 Prefer the gnulib copies of gettext.m4, glibc21.m4,
8364 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
8365 uintmax_t.m4, ulonglong.m4.
8366 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
8367 po.m4 since we are now using _gl.m4 instead.
8369 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
8371 * src/scan-action.l: Remove. Scanning of semantic actions is
8372 handled in scan-gram.l.
8374 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
8376 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
8378 * src/location.h (struct): The file member is a uniqstr.
8379 (equal_boundaries): Use UNIQSTR_EQ for comparison.
8381 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
8383 Fix bug with non-%union parsers that have printers or destructors,
8384 which led to a Bison core dump. Reported by Peter Fales in
8385 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
8387 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
8388 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
8389 not to our own type.
8390 * src/output.c (symbol_destructors_output, symbol_printers_output):
8391 Don't assume %union.
8392 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
8393 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
8394 UNION-FLAG. All callers changed.
8395 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
8396 Use type char, not unsigned int, when declaring an array of char;
8397 this lets us remove a cast.
8398 (Printers and Destructors): Add non-%union test cases.
8400 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8402 * doc/bison.texinfo: Minor editorial changes, mostly to the new
8403 GLR writeups. E.g., avoid frenchspacing and the future tense,
8404 change "lookahead" to "look-ahead", and change "wrt" to "with
8407 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8409 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
8410 New sections, split off from the GLR Parsers section. Put the new
8411 Simple GLR Parser near the start of the GLR section, for clarity.
8412 Rewrite connective text.
8414 2004-06-21 Frank Heckenbach <frank@g-n-u.de>

8469 * tests/calc.at, tests/actions.at: Workaround for SGI
8470 C++ compiler. (trivial change)
8472 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
8474 Spent a few hours checking out which prerequisite versions the
8475 current sources actually require. I went all the way back to
8476 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8477 a seemingly endless set of combinations of versions more recent
8478 than that. The bottom line is that the current sources require
8479 fairly recent versions of the build tools, and it'll be some work
8481 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
8482 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
8483 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
8484 Add comments explaining why those particular versions are
8487 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
8488 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
8489 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
8491 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
8492 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
8494 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8496 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
8497 0.11.5. Suggested by Bruno Haible.
8498 * bootstrap: Remove gettext version checking.
8500 * doc/bison.texinfo (Decl Summary): Also mention that %union
8501 can depend on prerequisite types. Problem reported by Tim
8504 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8506 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
8507 * README-alpha: Don't tell people not to package this.
8509 * bootstrap: Don't assume $(...) works; use `...` instead.
8510 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
8513 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
8514 put into the -d output file, and mention what to do if YYSTYPE is
8517 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8519 Undo change made earlier today: it caused autopoint to not bring
8520 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
8523 * bootstrap: Check that gettext version matches what's in
8524 configure.ac. Warn users to ignore robots.txt ERROR 404.
8525 * bootstrap: Undo today's earlier change (logged below).
8526 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
8528 The gettext version checking is causing more trouble than it's
8529 curing; remove it. Problem reported by Paul Hilfinger.
8531 * bootstrap: Issue a warning that one can expect a message
8532 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
8533 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
8535 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
8537 Ensure that the C++ compiler used for testing actually works on a
8538 simple test program; if not, skip the C++-related tests. Problem
8539 reported by Vin Shelton in:
8540 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
8542 * m4/cxx.m4: New file.

8549 * data/glr.c (yylloc): Output this macro even if locations are not
8550 being generated, as the GLR parser needs it even in that case.
8551 Problem reported by Troy A. Johnson
8552 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
8554 * configure.ac (AC_INIT): Update to 1.875e.

8560 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
8562 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
8563 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
8564 lalr1.cc runs afoul of the first, and the last two are no longer
8565 supported by GCC 3.4.0.
8566 * README: Mention GNU m4 1.4 or later; mention m4 patches.
8567 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
8569 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
8571 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
8572 unsigned int, for compatibility with latest gnulib hash module.
8573 * src/state.c (state_hash, state_hasher): Likewise.
8574 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.

8583 character and string literals.
8584 (unexpected_end): New function.
8585 (unexpected_eof): Use it.
8586 (unexpected_newline): New function.
8587 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
8590 * NEWS: Document %expect-rr.

8593 Fix typo by replacing $1 with $option.
8594 Remove more 'intl'-related files.
8595 Don't DEFUN AM_INTL_SUBDIR twice.
8597 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
8598 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
8600 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
8601 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
8602 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
8603 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
8604 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
8605 * src/.cvsignore: Add *.output.
8607 * src/parse-gram.y: Put copyright notice inside %{ %} so it
8608 gets copied to the output file.
8610 2004-04-28 Paul Eggert <eggert@twinsun.com>
8612 Get files from the gnulib and po repositories, instead of relying
8613 on them being in our CVS. Upgrade to latest versions of gnulib
8616 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
8617 * bootstrap: Bootstrap from gnulib and po repositories.
8618 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
8619 * README-cvs: Document these changes. Remove version numbers from
8620 mentions of build tools, since they change so often. Mention Flex.
8622 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
8623 (gl_USE_SYSTEM_EXTENSIONS): Add.
8624 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
8625 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
8627 (AC_ISC_POSIX): Remove; we no longer support this
8628 ancient OS, as it gets in the way of latest Autoconf & gnulib.
8629 (AC_HEADER_STDC): Remove: we now assume C89 or better.
8630 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
8631 Do not check for C89 headers, except for locale.h which is used
8632 by the Yacc library and must port to K&R hosts.
8633 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
8634 Do not check for C89 functions, except for setlocale which is
8635 used by the Yacc library.
8636 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
8637 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

8640 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
8641 AM_GNU_GETTEXT): Remove; now done by:
8642 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
8643 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
8646 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
8647 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
8648 Define to empty, as gnulib.mk will do the rest for us.
8649 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
8651 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
8652 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
8654 * src/files.c: Include gnulib's xstrndup.h.
8656 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
8657 (REALLOC): Use xnrealloc, for likewise.
8658 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
8659 (strnlen, memrchr): Remove decls; functions no longer used.
8662 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,
8663 lib/argmatch.h, lib/basename.c, lib/dirname.c, lib/dirname.h,

8683 Remove, as these files are now generated automatically
8684 by bootstrap or automake.
8686 * po/ChangeLog: Remove: all but one entry was a duplicate
8687 of this file, and I moved that 2000-11-02 entry here.
8689 * config/.cvsignore: Add Makefile, depcomp, install-sh.
8690 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

8706 * src/.cvsignore: Remove *_.c.
8709 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
8710 support it. (The latest stable gzip doesn't.)
8712 2004-04-27 Paul Eggert <eggert@twinsun.com>
8714 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
8715 case, as stos_ is now used by destructors due to the 2004-02-09
8718 Remove more K&R C support.
8719 * lib/libiberty.y (PARAMS): Remove. All uses removed.
8720 * lib/subpipe.c (errno): Remove decl.
8721 Include <stdlib.h> unconditionally.
8722 (EXIT_FAILURE): Remove macro.
8723 * src/complain.c (vfprintf, strerror): Remove.
8724 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
8726 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
8727 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
8728 (strchr, strspn, memchr): Remove decls.
8729 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
8730 unconditionally. Do not declare perror.

8737 with latest obstack.h.
8738 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
8739 to procedure types, as obstack.h now does that for us.
8740 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
8742 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
8743 so that this include file can stand alone.
8744 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
8745 does this now. Include subpipe.h first after config.h, to
8746 test whether it can stand alone.
8748 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
8749 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
8752 * tests/synclines.at (%union synch line): Put a dummy member in
8753 the union, because empty unions aren't allowed in C. Caught
8756 2004-04-13 Jim Meyering <jim@meyering.net>
8758 * src/conflicts.c (conflicts_print): Correct format string typo:
8759 use `%%' to produce literal `%'. (trivial change)
8761 2004-03-30 Paul Eggert <eggert@twinsun.com>
8763 * src/getargs.c (version): Update copyright year to 2004.

8804 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
8805 (declaration): Replace expected_conflicts with expected_sr_conflicts.
8806 Add %expect-rr rule.
8808 * src/scan-gram.l: Recognize %expect-rr.
8810 * src/conflicts.h (expected_sr_conflicts): Rename from
8812 (expected_rr_conflicts): Declare.
8814 * src/conflicts.c (expected_sr_conflicts): Rename from
8816 (expected_rr_conflicts): Define.
8817 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
8819 Use expected_sr_conflicts in place of expected_conflicts.
8820 Warn if expected_rr_conflicts used in non-GLR parser.
8822 * doc/bison.texinfo: Add documentation for %expect-rr.
8824 2004-03-08 Paul Eggert <eggert@gnu.org>
8826 Add support for hex token numbers. Suggested by Odd Arild Olsen in
8827 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
8829 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
8831 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
8832 * src/scan-gram.l (scan_integer): New function.
8834 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
8835 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
8836 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
8837 Say "long int", not "long", for uniformity with GNU style.
8839 2004-02-25 Paul Eggert <eggert@twinsun.com>
8841 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
8842 compilers. This fixes a problem with Intel's C++ compiler being
8843 chatty, reported by Guido Trentalancia in
8844 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
8846 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
8848 Support %destructor and merge error locations in lalr1.cc.
8850 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
8851 (Parser::stos_): Define unconditionally.

8855 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
8856 token which are discarded.
8857 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
8858 error_start_ when erroneous token are discarded.
8859 (Parser::parse) <yyerrlab1>: Compute the location of the error
8860 token so that it covers all the discarded tokens.
8861 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
8862 it can be called with `%skeleton "lalr1.cc"', and do that.
8864 2004-02-02 Paul Eggert <eggert@twinsun.com>
8866 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
8867 $(top_srcdir)/lib and ../lib. This fixes a bug reported
8868 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
8869 There's no need to mention top_builddir since Automake does that
8871 (INCLUDES): Remove, as Automake says it's obsolescent.
8872 Contents migrated into AM_CPPFLAGS as described above.
8873 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
8875 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8877 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
8878 (yyreportSyntaxError): Handle case where lookahead token is
8881 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8883 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
8884 resulting parsers are compilable with C++.
8886 2003-12-23 Paul Eggert <eggert@twinsun.com>
8888 * config/depcomp, config/install-sh: Sync with Automake 1.8.
8889 * src/output.c (output_skeleton): Rename local var.
8890 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
8891 Bison tokens, as this runs afoul of the 2003-10-07 change that
8892 disallowed NUL bytes in character constants or string literals.
8894 * tests/local.at: Require Autoconf 2.59's Autotest.
8895 * tests/testsuite.at: Don't include local.at, since we now assume
8896 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
8898 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
8899 multiple inclusion warnings.
8901 2003-12-02 Akim Demaille <akim@epita.fr>
8903 * doc/bison.texinfo (How Can I Reset the Parser): More about start
8907 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>

8911 2003-10-07 Paul Eggert <eggert@twinsun.com>
8913 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
8914 if testsuite doesn't exist.
8916 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
8917 literals, unfortunately.
8918 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
8919 Complain about NUL bytes in character constants or string literals.
8921 2003-10-05 Paul Eggert <eggert@twinsun.com>
8923 * NEWS: Don't document %no-default-prec, as it's still
8925 * doc/bison.texinfo: Document %no-default-prec only if
8926 the defaultprec flag is set. Normally it's not.
8928 2003-10-04 Paul Eggert <eggert@twinsun.com>
8930 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
8931 non-modifiable lvalue, instead of a modifiable one.
8932 * doc/bison.texinfo (Actions): Document that $$ can
8933 be assigned to. Do not claim that $$ and $N are
8934 array element references: user code should not rely on this.
8936 2003-10-01 Paul Eggert <eggert@twinsun.com>
8938 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
8939 (grammar_declaration): Use it.

8944 2003-10-01 Akim Demaille <akim@epita.fr>
8946 VCG no longer supports long_straight_phase.
8948 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
8949 * src/print_graph.c (print_graph): Adjust.
8951 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
8952 and Paul Eggert <eggert@twinsun.com>
8954 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
8955 Table of Symbols): Document %default-prec.
8956 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
8957 (grammar_declaration): Set default_prec on %default-prec.
8958 * src/scan-gram.l (%default-prec): New token.
8959 * src/reader.h (default_prec): New flag.
8960 * src/reader.c: Likewise.
8961 (packgram): Handle it.
8962 * tests/conflicts.at (%default-prec without %prec,
8963 %default-prec with %prec, %default-prec 1): New tests.
8965 2003-09-30 Paul Eggert <eggert@twinsun.com>
8967 * tests/testsuite.at: Include local.at, not input.at, fixing
8968 a typo in the 2003-08-25 patch.
8970 2003-08-27 Akim Demaille <akim@epita.fr>
8972 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
8975 2003-08-26 Akim Demaille <akim@epita.fr>
8977 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
8978 "<\#" to avoid magic from Gnus when posting parts of this script.
8980 2003-08-26 Akim Demaille <akim@epita.fr>
8982 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
8983 (Parser::parse): here.
8984 Adjust: nerrs and errstatus is now replaced by...
8985 (Parser::nerrs_, Parser::errstatus_): New.
8987 2003-08-25 Akim Demaille <akim@epita.fr>
8989 * config/announce-gen, Makefile.cfg: New.
8990 * Makefile.am: Adjust.
8991 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
8992 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
8994 2003-08-25 Akim Demaille <akim@epita.fr>
8996 When reducing initial empty rules, Bison parser read an initial
8997 location that is not defined. This results in garbage, and that
8998 affects Bison's own parser. Therefore we need (i) to extend Bison
8999 to support a means to initialize this location, and (ii) to use
9000 this CVS Bison to fix CVS Bison's parser.
9002 * src/reader.h, reader.c (epilogue_augment): Remove, replace
9004 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
9005 * src/parse-gram.y: Adjust.
9006 (%initial-action): New.
9007 (%error-verbose): Since we require CVS Bison, there is no reason
9009 * src/scan-gram.l: Adjust.
9010 * src/Makefile.am (YACC): New, to make sure we use our own parser.
9011 * data/yacc.c (yyparse): Use b4_initial_action.
9013 2003-08-25 Akim Demaille <akim@epita.fr>
9015 * doc/bison.texinfo: Don't promote stdout for error messages.
9017 2003-08-25 Akim Demaille <akim@epita.fr>
9019 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
9020 From Alexandre Duret-Lutz.
9022 2003-08-25 Akim Demaille <akim@epita.fr>
9026 2003-08-25 Akim Demaille <akim@epita.fr>
9028 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
9031 2003-08-25 Akim Demaille <akim@epita.fr>
9033 * data/lalr1.cc (Parser::reduce_print_): New.
9036 2003-08-25 Akim Demaille <akim@epita.fr>
9038 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
9039 error recovery loops. This patch is based on
9040 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
9041 Also, augment the similarity between lalr1.cc and yacc.c.
9042 Note: the locations of error recovery rules are not correct yet.
9044 * data/lalr1.cc: Comment changes to augment the similarity between
9045 lalr1.cc and yacc.c.
9046 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
9047 (yyerrlab1): Remove, but where it used to be (now the bottom part of
9048 yyerrlab), when hitting EOF, pop the whole stack here instead of
9049 merely falling thru the default error handling mechanism.
9050 (yyerrorlab): New label, with the old contents of YYERROR,
9051 plus the following change: pop the stack of rhs corresponding
9052 to the production that invoked YYERROR. That is how Yacc
9053 behaves (required by POSIX).
9054 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
9057 2003-08-25 Akim Demaille <akim@epita.fr>
9059 Tune local.at so that people can "autom4te -l autotest calc.at -o
9060 calc" for instance, to extract a sub test suite.
9062 * tests/testsuite.at: Move the initialization, Autotest version
9063 requirement, and AT_TESTED invocation into...
9064 * tests/local.at: here.
9065 * tests/testsuite.at: Include it for compatibility with Autoconf
9067 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
9070 2003-08-04 Paul Eggert <eggert@twinsun.com>
9072 Rework code slightly to avoid gcc -Wtraditional warnings.
9073 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
9074 The returned value is now stored in *YY0. All callers changed.
9075 * src/output.c (merge_output): Adjust to the above change.
9077 2003-07-26 Paul Eggert <eggert@twinsun.com>
9079 * data/glr.c (YYASSERT): New macro.
9080 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
9081 yyresolveStates, yyprocessOneStack):
9082 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
9083 Derived from a suggestion by Frank Heckenbach.
9085 2003-07-25 Paul Eggert <eggert@twinsun.com>
9087 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
9088 for portability to K&R C (after ansi2knr, presumably). See
9089 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
9090 by Frank Heckenbach, though I have omitted the structure-initialization
9091 part of his glr-knr.diff patch since I recall that the Portable
9092 C Compiler didn't require that change.
9094 Let the user specify how to allocate and free memory.
9095 Derived from a suggestion by Frank Heckenbach in
9096 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
9097 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
9098 All uses of free, malloc, realloc changed to use these macros,
9099 and unnecessary casts removed.
9100 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
9102 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
9104 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
9105 use s.empty() rather than s == "" to test for empty string; see
9106 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>

9111 * config/depcomp, config/install-sh: Update from masters.
9113 2003-06-20 Paul Eggert <eggert@twinsun.com>
9115 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
9116 and return properly parenthesized result.
9117 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
9118 * data/yacc.c (YYLLOC_DEFAULT): Likewise.

9121 conventions for parentheses.
9123 2003-06-19 Paul Eggert <eggert@twinsun.com>
9125 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
9126 yyreportTree): Do not assume that size_t is the same width as int,
9127 when printing sizes. Print sizes using an unsigned format.
9128 Problem reported by Frank Heckenbach in
9129 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
9131 Port to Forte Developer 7 C compiler.
9132 * data/glr.c (struct YYLTYPE): If locations are not being used,
9133 declare a single dummy member, as empty structs do not conform
9135 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
9136 the Forte Developer 7 C compiler complains that end-of-loop
9137 code is not reached.
9139 2003-06-17 Paul Eggert <eggert@twinsun.com>
9141 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
9142 avoid warnings from picky compilers about redefinition of PARAMS.
9144 2003-06-17 Paul Eggert <eggert@twinsun.com>
9148 * NEWS: Document 1.875b.
9150 * lib/bbitset.h: Do not include config.h; that's the includer's job.
9151 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
9152 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
9153 Don't use 'index' in comments, as it's a builtin fn on some hosts.
9154 * lib/bitset_stats.c: Include gettext.h unconditionally, as
9155 per recent gettext manual's suggestion.
9156 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
9157 Use prototypes, not old-style definitions.

9173 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
9174 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
9175 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
9176 * lib/vbitset.c, lib/vbitset.h: New files.
9177 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
9178 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
9181 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
9182 `How Can I Reset @code{yyparse}', since texinfo does not allow
9183 arbitrary @ in node names.
9185 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
9186 shouldn't be needed according to the gettext 0.12.1 documentation
9187 but which seem to be needed anyway: codeset.m4 glibc21.m4
9188 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
9189 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

9192 * lib/.cvsignore: Add stdbool.h.
9193 * m4/.cvsignore: Add nls.m4, po.m4.
9195 Upgrade to CVS gnulib.
9196 * stdbool_.h: File renamed from stdbool.h.in.
9197 * configure.ac (AM_STDBOOL_H): Invoke this instead of
9199 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
9200 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
9201 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
9202 (MOSTLYCLEANFILES): New var.
9203 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
9204 (stdbool.h): New rule.
9205 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
9206 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
9207 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
9208 m4/quote.m4: Upgrade to today's gnulib.
9210 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
9211 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
9212 the tests right now.
9213 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
9214 yyerror are declared before use; C99 requires this.
9216 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9218 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
9220 (yyrecoverSyntaxError): Correct the logic for setting and testing
9222 Correct comment on handling EOF.
9223 Allow states with only a default reduction, rather than failing
9224 (I can't quite reconstruct why these were not allowed before).
9226 Fixes to avoid problem that $-N rules in GLR parsers can cause
9227 buffer overruns, corrupting state.
9229 * src/output.c (prepare_rules): Output max_left_semantic_context
9231 * src/reader.h (max_left_semantic_context): New variable declaration.
9232 * src/scan-gram.l (max_left_semantic_context): Define.
9233 (handle_action_dollar): Update max_left_semantic_context.
9234 * data/glr.c (YYMAXLEFT): New definition.
9235 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
9236 (yyresolveAction): Ditto.
9238 Fixes to problems with location handling in GLR parsers reported by
9239 Frank Heckenbach (2003/06/05).
9241 * data/glr.c (YYLTYPE): Make trivial if locations not used.
9242 (YYRHSLOC): Add parentheses, and define only if locations used.
9243 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
9245 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
9246 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
9248 * tests/cxx-type.at: Exercise location information; update tests
9249 to differentiate output with and without locations.
9250 Remove forward declarations of yylex and yyerror---caused errors
9251 because default YYLTYPE not yet defined.
9252 Change semantic actions to compute strings, rather than printing
9253 them directly (to test proper passing of semantics values). Change
9254 output to prefix notation and update test data and expected results.
9255 (yylex): Track locations.
9256 (stmtMerge): Return value rather than printing, and include arguments
9259 2003-06-03 Paul Eggert <eggert@twinsun.com>
9261 Avoid warnings generated by GCC 2.95.4 when Bison is
9262 configured with --enable-gcc-warnings.
9263 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
9264 yy::]b4_parser_class_name[::translate_,
9265 yy::Stack::operator[] (unsigned),
9266 yy::Stack::operator[] (unsigned) const,
9267 yy::Slice::operator[] (unsigned),
9268 yy::Slice::operator[] (unsigned) const):
9269 Rename local vars to avoid warnings.
9270 * tests/glr-regression.at (Improper handling of embedded actions
9271 and $-N in GLR parsers): Remove unused local variable from yylex.
9272 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
9273 (void) as arg when not pure, since we now assume C89 when building
9274 Bison. Pacify GCC by using parameter.
9276 2003-06-02 Paul Eggert <eggert@twinsun.com>
9278 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
9279 yy::Location::lines, yy::Location::columns): Rename arguments
9280 to avoid shadowing; this removes a warning generated by GCC 3.3.
9282 2003-06-01 Paul Eggert <eggert@twinsun.com>
9284 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
9285 to g++, as GCC 3.3 complains if you do it.
9286 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
9287 everything that WARNING_CFLAGS has, except omit warnings
9288 not suitable for C++.
9289 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
9290 * tests/atlocal.in (CXXFLAGS): New var.
9291 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
9293 Fix a GLR parser bug I reported in February; see
9294 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
9295 The problem was that GLR parsers did not conform to the C standard,
9296 because actions like { $1 = $2 + $3; } expanded to expressions
9297 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9298 to a local variable. The C standard says that expressions
9299 like (var = f ()) + (var = f ()) have undefined behavior.
9300 Another problem was that GCC sometimes issues warnings that
9301 yyfill and its parameters are unused.
9303 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9305 (yyfill): New function.
9307 (yyuserAction): Change type of yynormal to bool, so that it matches
9308 the new yyfill signature. Mark it as possibly unused.
9311 Follow up on a bug I reported in February, where a Bison-generated
9312 parser can loop. Provide a test case and a fix for yacc.c. I
9313 don't have a fix for lalr1.cc or for glr.c, unfortunately.
9314 The original bug report is in:
9315 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
9317 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
9318 macro's size was becoming unwieldy.
9319 (yyerrlab): Do not discard an empty lookahead symbol, as this
9320 might destroy garbage.
9321 (yyerrorlab): New label, with the old contents of YYERROR,
9322 plus the following change: pop the stack of rhs corresponding
9323 to the production that invoked YYERROR. That is how Yacc
9324 behaves, and POSIX requires this behavior.
9325 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
9326 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
9327 Define 'alarm' to do nothing if unistd.h is not available.
9328 Add a new rule "exp: '-' error;" to test the above change to
9329 data/yacc.c. Use 'alarm' to abort any test taking longer than
9330 10 seconds, as it's probably looping.
9331 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
9332 Also, the new yacc.c generates two fewer diagnostics for an
9335 2003-05-24 Paul Eggert <eggert@twinsun.com>
9337 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
9338 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
9339 This fixes a problem reported by John Bowman when the Compaq/HP
9340 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
9342 * data/yacc.c (union yyalloc): Likewise.
9343 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
9345 Switch from 'int' to 'bool' where that makes sense.
9347 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
9348 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
9349 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
9350 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
9351 Return or accept bool, not int. All callers changed.
9352 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
9353 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

9370 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
9371 lbitset_xor_cmp): Likewise.
9372 * lib/bbitset.h: Include <stdbool.h>.
9373 (struct bitset_vtable): The following members now return bool, not
9374 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
9375 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
9377 * src/conflicts.c (count_rr_conflicts): Likewise.
9378 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
9380 * lib/ebitset.c (ebitset_obstack_init): Likewise.
9381 * lib/lbitset.c (lbitset_obstack_init): Likewise.
9382 * src/getargs.c (debug_flag, defines_flag, locations_flag,
9383 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
9384 graph_flag): Likewise.
9385 * src/getargs.h (debug_flag, defines_flag, locations_flag,

9390 * src/reader.c (start_flag, typed): Likewise.
9391 * src/reader.h (typed): Likewise.
9392 * src/getargs.c (LOCATIONS_OPTION): New constant.
9393 (long_options, getargs): Use it.
9394 * src/lalr.c (build_relations): Use bool, not int.
9395 * src/nullable.c (nullable_compute): Likewise.

9398 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
9399 * src/output.c (prepare): Use it.
9400 * src/output.c (token_definitions_output,
9401 symbol_destructors_output, symbol_destructors_output): Use string,
9402 not boolean integer, to keep track of whether to output separator.
9403 * src/print_graph.c (print_core): Likewise.
9404 * src/state.c (state_rule_lookaheads_print): Likewise.
9406 * config/install-sh: Sync from automake 1.7.5.
9408 2003-05-14 Paul Eggert <eggert@twinsun.com>
9410 * src/parse-gram.y (rules_or_grammar_declaration): Require a
9411 semicolon after a grammar declaration, in the interest of possible
9412 future changes to the Bison input language.
9413 Do not allow a stray semicolon at the start of the grammar.
9414 (rhses.1): Allow one or more semicolons after any rule, including
9415 just before "|" as required by POSIX.
9416 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
9419 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
9421 %parse-param support for lalr1.cc.
9423 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
9424 b4_cc_constructor_calls, b4_cc_constructor_call,
9425 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
9427 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
9428 parse-param arguments.
9429 (yy::b4_parser_class_name): Declare instance variables to
9430 hold parse-param arguments.
9431 * tests/calc.at: s/value/semantic_value/ because value clashes
9432 with a member of yy::b4_parser_class_name. Adjust C++ code
9433 to handle %parse-param. Enable %parse-param test in C++.
9435 2003-05-12 Paul Eggert <eggert@twinsun.com>
9437 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
9438 English a bit. Fix fclose typo. Change "const char" to "char
9439 const", and use ANSI C rather than K&R for "main". Suggest
9440 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
9441 and suggest yy_switch_to_buffer.
9443 2003-05-05 Paul Eggert <eggert@twinsun.com>
9445 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
9446 C89. This avoids a diagnostic on compilers that define __STDC__
9447 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
9448 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9450 2003-05-03 Paul Eggert <eggert@twinsun.com>
9452 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
9453 Do not overrun array bounds.
9454 This should fix a bug reported today by Olatunji Oluwabukunmi in
9455 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
9457 2003-04-29 Akim Demaille <akim@epita.fr>
9459 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
9460 * src/getargs.c, src/getargs.h: here, as bool, not int.
9461 (nondeterministic_parser): New.
9462 * src/parse-gram.y, src/scan-gram.l: Support
9463 %nondeterministic-parser.
9464 * src/output.c (prepare): Use nondeterministic_parser instead
9465 of glr_parser where appropriate.
9466 * src/tables.c (conflict_row, action_row, save_row)
9467 (token_actions, token_actions, pack_vector): Ditto.
9469 2003-04-29 Akim Demaille <akim@epita.fr>
9471 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
9473 2003-04-29 Akim Demaille <akim@epita.fr>
9475 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
9476 with %pure-parser and %locations to exercise the patch from Yakov
9479 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
9481 * data/yacc.c: (b4_lex_param): Corrected for the case where
9482 %lex-param is provided and %pure-parser isn't.
9484 2003-04-27 Paul Eggert <eggert@twinsun.com>
9486 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
9487 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
9488 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
9489 if it is not defined.
9490 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
9492 2003-04-26 Paul Eggert <eggert@twinsun.com>
9494 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
9495 Declare to be of type suitable for the ninf value itself, not of
9496 type suitable for the corresponding table, since the latter might
9497 be unsigned but the ninf value might be negative. This fixes a
9498 bug reported by Alexandre Duret-Lutz in
9499 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
9501 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
9502 invokes it. We shouldn't invoke it twice because it will attempt
9503 to put error.o in the archive twice. This fixes a glitch reported
9504 by Martin Mokrejs in
9505 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9507 2003-04-21 Paul Eggert <eggert@twinsun.com>
9509 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
9512 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
9514 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
9515 Fix obvious typo that results in uncompilable GLR parsers
9516 when both %pure-parser and %locations are used. (trivial change)
9518 2003-04-17 Paul Eggert <eggert@twinsun.com>
9520 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
9521 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
9522 Do not insert the expected token via unput, as this runs afoul
9523 of a POSIX-compatibility bug in flex 2.5.31.
9524 All uses changed to BEGIN the parent state,
9525 since we no longer insert the expected token via unput.
9526 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
9527 that is no longer emitted after the above change.
9529 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
9530 the first one. This change is from Paul Hilfinger, and it fixes
9531 regression reported by Werner Lemberg in
9532 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
9534 (resolve_sr_conflict): Don't invoke state_errs_set
9535 unless one or more tokens have been explicitly made errors.
9536 Otherwise, the above change causes Bison to abort.
9538 * tests/existing.at (GNU pic Grammar): New test case, taken from
9541 2003-03-31 Akim Demaille <akim@epita.fr>
9543 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
9545 2003-03-31 Akim Demaille <akim@epita.fr>
9547 * src/output.c (prepare_symbols): Avoid trailing spaces in the
9550 2003-03-31 Akim Demaille <akim@epita.fr>
9552 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
9553 From Paul Hilfinger.
9555 2003-03-29 Akim Demaille <akim@epita.fr>
9557 * m4/error.m4: Do not put under dynamic conditions some code which
9558 expansion is under static control.
9560 2003-03-29 Akim Demaille <akim@epita.fr>
9562 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
9564 2003-03-29 Akim Demaille <akim@epita.fr>
9566 * doc/bison.texinfo (Strings are Destroyed): New.
9568 2003-03-13 Paul Eggert <eggert@twinsun.com>
9570 * .cvsignore: Add configure.lineno.
9571 * src/.cvsignore: Add yacc.
9572 * tests/.cvsignore: Add testsuite.log.
9573 * doc/fdl.texi: Sync with latest FSF version.
9575 2003-03-12 Paul Eggert <eggert@twinsun.com>
9577 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
9578 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
9579 cursor, instead of leaving it undefined. This fixes a bug
9580 reported by Tim Van Holder in
9581 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
9582 * tests/input.at (Torturing the Scanner): Test the scanner on
9583 an empty input file, which was Tim Van Holder's test case.
9585 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
9586 <sys/resource.h> can be included, include sys/time.h and
9587 sys/times.h first, if available. This works around the SunOS
9588 4.1.4 porting bug reported by Bruce Becker in
9589 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
9591 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
9592 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
9595 Merge changes from gnulib. This was prompted because the CVS
9596 snapshot didn't build on Solaris 7 due to strnlen problems.
9598 These changes need to be merged back into gnulib:
9599 * lib/hash.c: Include <stdbool.h> unconditionally.
9600 * m4/onceonly.m4 (m4_quote): New macro.
9601 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
9602 Quote AC_FOREACH variable-expansions properly.
9603 The 2003-01-03 obstack.h change also needs merging.
9604 {end of changes requiring merging}
9606 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
9607 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
9608 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
9609 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
9610 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
9611 New files, imported from gnulib.
9612 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
9615 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
9616 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
9619 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
9621 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
9622 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
9623 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
9624 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
9625 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
9626 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
9627 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
9628 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
9629 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
9630 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
9631 (jm_PREREQ_ARGMATCH): Remove.
9632 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
9633 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
9635 * src/system.h: Include <stdbool.h> unconditionally.
9637 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
9638 assuming at least C89 in the bitset code for some time now.
9640 2003-03-03 Akim Demaille <akim@epita.fr>
9644 2003-03-02 Akim Demaille <akim@epita.fr>
9646 * doc/bison.texinfo (Table of Symbols): Reactivate the
9647 documentation for %lex-param, and %parse-param.
9649 2003-03-02 Akim Demaille <akim@epita.fr>
9651 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
9652 generate verbose error messages.
9653 Use the number of tokens as an upper bound in yytname, as it
9654 cannot be a non terminal.
9656 2003-03-02 Akim Demaille <akim@epita.fr>
9658 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
9661 2003-03-02 Akim Demaille <akim@epita.fr>
9663 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
9664 Use them to exercise yycheck overrun.
9665 Based on Andrew Suffield's grammar.
9667 2003-03-02 Akim Demaille <akim@epita.fr>
9669 Create tests/local.at for Bison generic testing macros.
9671 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
9672 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
9674 * tests/calc.at (AT_CHECK_CALC): Adjust.
9675 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
9676 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
9677 * tests/local.at: here.
9678 (AT_COMPILE_CXX): Tags the tests using it as c++.
9679 Ignore the test if CXX is not functional.
9681 2003-03-01 Paul Eggert <eggert@twinsun.com>
9683 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
9684 not loc->end, since loc->end might contain garbage and this leads
9685 to undefined behavior on some platforms.
9686 (id_loc, token_start): Use (IF_LINTed) initial values that do not
9687 depend on *loc, so that the reader doesn't give the the false
9688 impression that *loc is initialized.
9689 (<INITIAL>"%%"): Do not bother setting code_start, since its value
9690 does not survive the return.
9692 2003-03-01 Akim Demaille <akim@epita.fr>
9694 * src/scan-gram.l (code_start): Always initialize it when entering
9695 into yylex, as SC_EPILOGUE is activated *before* the corresponding
9696 yylex invocation. An alternative would be making it static, but
9697 then it starts with the second %%'s beginning, instead of its end.
9699 2003-02-28 Paul Eggert <eggert@twinsun.com>
9701 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
9702 around a UnixWare 7.1.1 porting bug reported by John Hughes in
9703 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
9705 2003-02-26 Paul Eggert <eggert@twinsun.com>
9707 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
9708 Remove Sequent/Pyramid discussion (nobody uses them any more).
9709 Merge VMS and MS-DOS discussion; these ports may well be dead
9710 but let's keep mentioning them for now. Put <> around email
9711 addresses. Add copyright notice.
9713 2003-02-24 Paul Eggert <eggert@twinsun.com>
9715 * data/glr.c (yy_reduce_print): yylineno -> yylno,
9716 to avoid collision with flex use of yylineno.
9717 Problem reported by Bruce Lilly in
9718 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
9719 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9720 * data/yacc.c (yy_reduce_print): Likewise.

9724 2003-02-21 Akim Demaille <akim@epita.fr>
9726 * data/lalr1.cc: Use temporary variables instead of casts to
9727 change integer types.
9728 Suggested by Paul Eggert.
9730 2003-02-21 Akim Demaille <akim@epita.fr>
9732 * doc/bison.texinfo: Use "location" consistently to refer to @n,
9733 to avoid confusions with lalr1.cc's notion of Position.
9734 Suggested by Paul Eggert.
9736 2003-02-20 Akim Demaille <akim@epita.fr>
9738 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
9739 before initial_columns.
9740 (location.hh): Use consistent variable names when defining the
9742 Use "last" so that we subtract from Positions, not from unsigned.
9744 2003-02-20 Akim Demaille <akim@epita.fr>
9746 * data/lalr1.cc (position.hh): New subfile, including the extended
9747 and Doxygen'ed documentation of class Position.
9748 (location.hh): Use it.
9749 Document a` la Doxygen.
9750 With the help of Benoit Perrot.
9752 2003-02-20 Akim Demaille <akim@epita.fr>
9754 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
9756 Redefine AT_YYERROR_SEES_LOC_IF using it.
9757 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
9759 Don't use the location in yy::Parser::error_ and
9760 yy::Parser::print_ when not %locations.
9761 Activate more lalr1.cc tests.
9763 2003-02-19 Akim Demaille <akim@epita.fr>
9765 * data/lalr1.cc: When displaying a line number, be sure to make it
9768 2003-02-19 Akim Demaille <akim@epita.fr>
9770 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
9772 (YYABORT, YYACCEPT, YYERROR): New.
9773 * tests/calc.at: Renable the lalr1.cc test.
9775 2003-02-19 Akim Demaille <akim@epita.fr>
9777 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
9778 error recovery, mixing with/without pops and discarding of the
9781 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
9783 2003-02-17 Paul Eggert <eggert@twinsun.com>
9785 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
9786 * tests/testsuite.at (AT_COMPILE): Use them.
9787 This fixes the testsuite problem reported by Robert Lentz in
9788 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
9790 2003-02-12 Paul Eggert <eggert@twinsun.com>
9792 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
9793 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
9794 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
9795 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
9796 Check for malloc failure, for consistency with yacc.c.
9797 (yytname_size): Remove, for consistency with yacc.c.
9799 The bug still remains in data/lalr1.cc, as I didn't have time
9802 2003-02-06 Akim Demaille <akim@epita.fr>
9804 * configure.ac (GXX): Rename as...
9805 (CXX): this, to keep the original Autoconf semantics.
9807 * data/lalr1.cc: Fix b4_copyright invocations.
9808 If YYDEBUG is not defined, don't depend upon name_ being defined.
9809 (location.hh): Include string and iostream.
9810 (Position::filename): New member.
9811 (Position::Position ()): New.
9812 (operator<< (Position)): New.
9813 (operator- (Position, int)): New.
9814 (Location::first, Location::last): Rename as...
9815 (Location::begin, Location::end): these, to mock the conventional
9817 (operator<< (Location)): New.
9818 * tests/atlocal.in (CXX): New.
9819 * tests/testsuite.at (AT_COMPILE_CXX): New.
9820 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
9821 locations in a more synthetic way.
9822 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
9824 Adjust the C locations to match those from Emacs: first column is
9826 Change all the expected results.
9827 Conform to the GCS: simplify the locations when applicable.
9828 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
9829 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
9830 these CPP macros with the m4 macros new defined by...
9831 (AT_CHECK_PUSHDEFS): this, i.e.:
9832 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
9833 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
9835 (AT_CHECK_POPDEFS): Undefine them.
9836 (AT_CHECK_CALC_LALR1_CC): New.
9837 Use it for the first lalr1.cc test.
9839 2003-02-04 Akim Demaille <akim@epita.fr>
9841 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
9842 Location as is defined.
9844 2003-02-04 Akim Demaille <akim@epita.fr>
9846 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
9847 name_ being defined.
9849 2003-02-03 Paul Eggert <eggert@twinsun.com>
9851 * src/gram.h (start_symbol): Remove unused decl.
9853 Use more-consistent naming conventions for local vars.
9855 * src/derives.c (derives_compute): Change type of local var from
9857 * src/gram.c (grammar_rules_partial_print): Likewise.
9858 * src/print.c (print_core): Likewise.
9859 * src/reduce.c (reduce_grammar_tables): Likewise.
9861 * src/gram.c (grammar_dump): Change name of item_number *
9862 local var from r to rp.
9863 * src/nullable.c (nullable_compute): Likewise.
9865 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
9867 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
9868 for symbol or symbol_number var.
9869 * src/reader.c (grammar_start_symbol_set): Likewise.
9870 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
9872 * src/state.c (transitions_to): Likewise.
9873 * src/state.h: Likewise.
9874 * src/tables.c (symbol_number_to_vector_number): Likewise.
9876 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
9879 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
9882 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
9885 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
9886 Use str, not s, for char * var. Use ch, not c, for character var.
9887 Use size for size var.
9889 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
9891 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
9893 * src/uniqstr.h: Likewise.
9895 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
9896 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
9897 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
9898 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
9899 param to have same name as that of enum, so that we don't use
9900 "s" to stand for a non-state.
9902 2003-02-02 Akim Demaille <akim@epita.fr>
9904 * src/scan-skel.l: Scan more than one inert character per yylex
9907 2003-02-01 Paul Eggert <eggert@twinsun.com>
9911 * po/LINGUAS: Add ms.
9913 2003-01-30 Akim Demaille <akim@epita.fr>
9915 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
9917 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9919 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
9922 Changes in response to error report by S. Eken: GLR mode does not
9923 handle negative $ indices or $ indices in embedded rules correctly.
9924 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
9926 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
9927 (b4_rhs_location): Ditto.
9928 (yyfill): New function to copy from stack tree into array
9930 (yyuserAction): Modify to allow incremental move of semantic values
9931 to rhs array when in GLR mode.
9932 Define YYFILL to use in user-defined actions to fill semantic array
9934 Remove dummy use of yystack, as there is now a guaranteed use.
9935 (yydoAction): Modify to allow incremental move of semantic values
9936 to rhs array when in GLR mode.
9937 (yyresolveAction): Ditto.
9938 (yyglrShiftDefer): Update comment.
9939 (yyresolveStates): Use X == NULL for pointers, not !X.
9940 (yyglrReduce): Ditto.
9943 * tests/glr-regr1.at: Rename to ...
9944 * tests/glr-regression.at: Add new regression test for the problems
9945 described above (adapted from S. Eken).
9946 Update copyright notice.
9947 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
9948 * tests/Makefile.am: Ditto.
9950 2003-01-28 Paul Eggert <eggert@twinsun.com>
9952 * data/lalr1.cc: Do not use @output_header_name@ unless
9953 b4_defines_flag is set. This fixes two bugs reported by
9955 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
9956 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
9958 2003-01-21 Paul Eggert <eggert@twinsun.com>
9960 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
9961 we don't need to worry about yyerrlab1 being reported as an
9962 "unused label" by non-GCC C compilers. The downside is that if
9963 locations are used then a couple of statements are duplicated each
9964 time YYERROR is invoked, but the upside is that the warnings
9966 (yyerrlab1): Move code to YERROR.
9967 (yyerrlab2): Remove. Change uses back to yyerrlab1.
9968 This reverts some of the 2002-12-27 change.
9970 2003-01-17 Paul Eggert <eggert@twinsun.com>
9972 * src/output.c (symbol_printers_output): Fix typo that led
9973 to core dump. Problem reported by Antonio Rus in
9974 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
9976 2003-01-13 Akim Demaille <akim@epita.fr>,
9977 Quoc Peyrot <chojin@lrde.epita.fr>,
9978 Robert Anisko <anisko_r@lrde.epita.fr>
9980 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
9981 when the stacks contain one element, as the loop would otherwise
9982 free the last state, and then use the top state (the one we just
9983 popped). This means that the initial elements will not be freed
9984 explicitly, as is the case in yacc.c; it is not a problem, as
9985 these elements have fake values.
9987 2003-01-11 Paul Eggert <eggert@twinsun.com>
9989 * NEWS: %expect-violations are now just warnings, reverting
9990 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
9991 bootstrapping problem reported by Matthias Klose; see
9992 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
9993 * src/conflicts.c (conflicts_print): Likewise.
9994 * tests/conflicts.at (%expect not enough, %expect too much,
9995 %expect with reduce conflicts): Likewise.
9996 * doc/bison.texinfo (Expect Decl): Document this. Also mention
9997 that the warning is enabled if the number of conflicts changes
9998 (not necessarily increases).
10000 * src/getargs.c (version): Update copyright year.
10002 2003-01-09 Akim Demaille <akim@epita.fr>
10004 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
10006 2003-01-08 Paul Eggert <eggert@twinsun.com>
10008 * Makefile.maint (WGETFLAGS):
10009 New macro, containing "-C off" to disable proxy caches.
10010 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
10011 (rel-check): Use $(WGET) instead of wget.
10013 2003-01-06 Paul Eggert <eggert@twinsun.com>
10015 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
10016 the GLR paper of Scott, Johnstone and Hussain.
10018 2003-01-04 Paul Eggert <eggert@twinsun.com>
10020 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
10021 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
10022 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
10023 (EXTRA_LIBRARIES): New var, for liby.a.
10024 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
10025 (EXTRA_SCRIPTS): New var, for yacc.
10027 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
10028 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
10029 Problem reported by Nelson H. F. Beebe.
10031 2003-01-03 Paul Eggert <eggert@twinsun.com>
10033 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
10034 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
10035 when compiling Bison 1.875's `bitset bset = obstack_alloc
10036 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
10038 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
10039 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
10040 grow to a huge size with typical invocation.
10042 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
10043 Use the pattern recommended by Autoconf 2.57, except also protect
10044 against double-definition.
10045 * src/system.h: Likewise.
10046 Portability issues reported by Nelson H. F. Beebe.
10048 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
10049 All uses changed. Provide a definition in both C and C++.
10050 (yytrue, yyfalse): Define even if defined (__cplusplus).
10052 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
10053 Reported by Nelson H. F. Beebe.
10055 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
10057 2003-01-02 Paul Eggert <eggert@twinsun.com>
10059 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
10060 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
10061 Bug reported by Nelson H. F. Beebe.
10063 2003-01-01 Paul Eggert <eggert@twinsun.com>
10067 2002-12-30 Paul Eggert <eggert@twinsun.com>
10069 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
10071 (<INITIAL>","): Here. This causes stray "," to be treated
10074 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
10075 last brace in braced code when not in Yacc mode, for compatibility
10076 with Bison 1.35. This resurrects the 2001-12-15 patch to
10079 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
10080 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
10082 2002-12-28 Paul Eggert <eggert@twinsun.com>
10084 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
10085 that of SYM's type. This fixes Debian bug 168069, reported by
10088 2002-12-28 Paul Eggert <eggert@twinsun.com>
10092 Switch back to the Yacc style of conflict reports, undoing some
10093 of the 2002-07-30 change.
10094 * doc/bison.texinfo (Understanding): Use Yacc style for
10095 conflict reports. Also, use new way of locating rules.
10096 * src/conflicts.c (conflict_report):
10097 Renamed from conflict_report_yacc, removing the old
10098 'conflict_report'. Translate the entire conflict report at once,
10099 so that we don't assume that "," has the same interpretation in
10101 (conflicts_output): Use Yacc-style conflict report for each state,
10102 instead of our more-complicated style.
10103 (conflicts_print): Use Yacc-style conflict report, except print
10104 the input file name when not emulating Yacc.
10105 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
10106 Conflicted Reduction, %expect not enough, %expect too much,
10107 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
10108 * tests/existing.at (GNU Cim Grammar): Likewise.
10109 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
10111 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
10112 fatal): Don't invoke fflush; it's not needed and it might even be
10113 harmful for stdout, as stdout might not be open.
10114 * src/reduce.c (reduce_print): Likewise.
10116 2002-12-27 Paul Eggert <eggert@twinsun.com>
10118 Fix a bug where error locations were not being recorded correctly.
10119 This problem was originally reported by Paul Hilfinger in
10120 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
10122 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10123 top of the location stack's error locations.
10124 (yyerrlab): Set it. When discarding a token, push its location
10125 onto yylerrsp so that we don't lose track of the error's end.
10126 (yyerrlab1): Now is only the target of YYERROR, so that we can
10127 properly record the location of the action that failed. For GCC
10128 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10129 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10130 (yyerrlab2): New label, which yyerrlab now falls through to.
10131 Compute the error's location by applying YYLLOC_DEFAULT to
10132 the locations of all the symbols that went into the error.
10133 * doc/bison.texinfo (Location Default Action): Mention that
10134 YYLLOC_DEFAULT is also invoked for syntax errors.
10135 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10136 Error locations include the locations of all the tokens that were
10137 discarded, not just the last token.
10139 2002-12-26 Paul Eggert <eggert@twinsun.com>
10141 * src/files.c: Include quote.h.
10142 (compute_output_file_names): Warn if we detect conflicting
10143 outputs to the same file. This should catch the misunderstanding
10144 exemplified by Debian Bug 165349, reported by Bruce Stephens..
10146 * src/conflicts.c (conflicts_print): If the user specifies
10147 "%expect N", report an error if there are any reduce/reduce
10148 conflicts. This is what the manual says should happen.
10149 This fixes Debian bug 130890, reported by Anthony DeRobertis.
10150 * tests/conflicts.at (%expect with reduce conflicts): New test.
10152 Don't use m4_include on relative file names, as it doesn't work as
10153 desired if there happens to be a file with that name under ".".
10155 * m4sugar/version.m4: Remove; it was included but it wasn't used.
10156 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
10157 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
10158 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
10159 * src/output.c (output_skeleton): Use full path names when
10160 specifying a file to include; don't rely on include path, as
10161 it's unreliable when the working file contains a file with
10164 2002-12-25 Paul Eggert <eggert@twinsun.com>
10166 Remove obsolete references to bison.simple and bison.hairy.
10167 Problem mentioned by Aubin Mahe in
10168 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
10169 * data/glr.c: Comment fix.
10170 * doc/bison.1: Remove references. Also, mention "yacc".
10172 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
10175 * src/parse-gram.y (declaration): Use enum "report_states" rather
10176 than its numeric value 1.
10178 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
10179 opening a new one. This fixes Debian bug 165349, reported by
10182 2002-12-24 Paul Eggert <eggert@twinsun.com>
10186 * Makefile.maint (cvs-update): Don't assume that the shell
10187 supports $(...), as Solaris sh doesn't.
10189 * src/parse-gram.y (lloc_default): Remove test for empty
10190 nonterminals at the end, since it didn't change the result.
10192 2002-12-24 Paul Eggert <eggert@twinsun.com>
10194 If the user does not define YYSTYPE as a macro, Bison now declares it
10195 using typedef instead of defining it as a macro. POSIX requires this.
10196 For consistency, YYLTYPE is also declared instead of defined.
10198 %union directives can now have a tag before the `{', e.g., the
10199 directive `%union foo {...}' now generates the C code
10200 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10201 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10202 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10203 instead of `yyltype'.
10205 `yystype' and `yyltype' are now obsolescent macros instead of being
10206 typedefs or tags; they are no longer documented and will be
10207 withdrawn in a future release.
10209 * data/glr.c (b4_location_type): Remove.
10210 (YYSTYPE): Renamed from yystype.
10211 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
10212 (struct YYLTYPE): Renamed from struct yyltype.
10213 (YYLTYPE): Renamed from yyltype.
10214 (yyltype, yystype): New (and obsolescent) macros,
10215 for backward compatibility.
10216 * data/yacc.c: Likewise.
10218 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10219 does not specify a union tag. This is for compatibility with
10222 * src/parse-gram.y (add_param): 2nd arg is now char * not char
10223 const *, since it is now modified by stripping surrounding { }.
10224 (current_braced_code): Remove.
10225 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
10226 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
10227 trailing " {...}". Now of type <chars>.
10228 (grammar_declaration): Adjust to bundled tokens.
10229 (code_content): Remove; stripping is now done by add_param.
10230 (print_token_value): Print contents of bundled tokens.
10231 (token_name): New function.
10233 * src/reader.h (braced_code, current_braced_code): Remove.
10234 (token_name): New decl.
10236 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
10237 token_type, not braced_code code_kind. All uses changed.
10238 (SC_PRE_CODE): New state, for scanning after a keyword that
10239 has (or usually has) an immediately-following braced code.
10240 (token_type): New local var, to keep track of which token type
10241 to return when scanning braced code.
10242 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
10243 <INITIAL>"%parse-param", <INITIAL>"%printer",
10244 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
10245 instead of returning a token type immediately.
10246 (<INITIAL>"{"): Set token type.
10247 (<SC_BRACED_CODE>"}"): Use it.
10248 (handle_action_dollar, handle_action_at): Now returns bool
10249 indicating success. Fail if ! current_rule; this prevents a core dump.
10250 (handle_symbol_code_dollar, handle_symbol_code_at):
10251 Remove; merge body into caller.
10252 (handle_dollar, handle_at): Complain in invalid contexts.
10254 * NEWS, doc/bison.texinfo: Document the above.
10255 * NEWS: Fix years and program names in copyright notice.
10257 2002-12-17 Paul Eggert <eggert@twinsun.com>
10259 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
10260 Reporting, Table of Symbols): Omit mentions of %lex-param and
10261 %parse-param from the documentation for now.
10263 2002-12-15 Paul Eggert <eggert@twinsun.com>
10265 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
10266 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10267 lookahead symbol, and which sets yychar in parser actions) and it
10268 disagreed with the Bison documentation. Bug
10269 reported by Andrew Walrond.
10271 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
10272 as the caller now does that.
10273 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
10274 (YYEMPTY): Parenthesize right hand side, since others use it.
10275 (yyparse): Don't assume that our generated code is the only code
10278 2002-12-13 Paul Eggert <eggert@twinsun.com>
10282 POSIX requires a "yacc" command.
10283 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
10284 (MOSTLYCLEANFILES): Add yacc.
10286 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
10287 as an alias for bison y.
10289 * po/LINGUAS: Add da.
10291 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
10292 problem with latest <getopt.h>.
10293 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
10295 * doc/fdl.texi: Upgrade to 1.2.
10296 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
10297 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
10298 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
10300 * config/install-sh: Sync with autotools.
10302 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
10303 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10304 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
10305 locations are requested.
10306 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
10307 locations are requested.
10309 2002-12-12 Paul Eggert <eggert@twinsun.com>
10311 Remove unportable casts and storage allocation tricks.
10312 While we're at it, remove almost all casts, since they
10313 usually aren't needed and are a sign of trouble.
10315 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
10317 * src/derives.c (derives_compute): Do not subtract NTOKENS from
10318 the pointer DSET returned by malloc; this isn't portable.
10319 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
10320 Similarly for DERIVES.
10321 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
10322 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
10323 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
10325 * src/derives.c (derives_compute): Do not bother invoking
10326 int_of_rule_number, since rule numbers are integers.
10328 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
10329 rather than XMALLOC (char, N).
10331 * src/files.c (filename_split): Rewrite to avoid cast.
10333 * src/gram.h (symbol_number_as_item_number,
10334 item_number_as_symbol_number, rule_number_as_item_number,
10335 item_number_as_rule_number):
10336 Now inline functions rather than macros, to avoid casts.
10337 * src/state.h (state_number_as_int): Likewise.
10338 * src/tables.c (state_number_to_vector_number,
10339 symbol_number_to_vector_number): Likewise.
10341 * src/gram.h (int_of_rule_number): Remove; no longer used.
10343 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
10344 since the resulting storage is always stored into.
10346 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
10349 * src/muscle_tab.c (muscle_m4_output):
10350 Now inline. Return bool, not int.
10351 * src/state.c (state_compare): Likewise.
10352 * src/symtab.c (symbol_check_defined,
10353 symbol_check_alias_consistency, symbol_pack, symbol_translation,
10354 hash_compare_symbol, hash_symbol):
10356 * src/uniqstr.c (uniqstr_print): Likewise.
10357 * src/muscle_tab.c (muscle_m4_output_processor):
10358 New function, to avoid casts.
10359 * src/state.c (state_comparator, stage_hasher): Likewise.
10360 * src/symtab.c (symbol_check_defined_processor,
10361 symbol_check_alias_consistency_processor, symbol_pack_processor,
10362 symbol_translation_processor, hash_symbol_comparator,
10363 hash_symbol_hasher): Likewise.
10364 * src/uniqstr.c (uniqstr_print_processor): Likewise.
10365 * src/muscle_tab.c (muscles_m4_output):
10366 Use new functions instead of casting old functions unportably.
10367 * src/state.c (state_hash_new): Likewise.
10368 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
10369 symbols_token_translations_init):
10371 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
10373 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
10374 var instead of casting to long, to avoid casts.
10375 (prepare_states): Use MALLOC rather than alloca, so that we don't
10376 have to worry about alloca.
10377 * src/state.c (state_hash_lookup): Likewise.
10379 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
10380 local var instead of casting to unsigned char, to avoid casts.
10382 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
10383 STATE_ALLOC): Remove.
10384 (transitions_new, errs_new, reductions_new, state_new): Use malloc
10385 rather than calloc, and use offsetof to avoid allocating slightly
10387 (state_new): Initialize all members.
10389 * src/state.c (state_hash): Use unsigned accumulator, not signed.
10391 * src/symtab.c (symbol_free): Remove; unused.
10392 (symbol_get): Remove cast in lhs of assignment.
10393 (symbols_do): Now static. Accept generic arguments, not
10394 hashing-related ones.
10396 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
10397 (symbol_processor): Remove.
10398 (symbols_do): Remove decl; now static.
10400 * src/system.h (alloca): Remove; decl no longer needed.
10401 (<stddef.h>): Include, for offsetof.
10402 (<inttypes.>, <stdint.h>): Include if available.
10403 (uintptr_t): New type, if system lacks it.
10404 (CALLOC, MALLOC, REALLOC): New macros.
10405 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
10408 * src/tables.c (table_size): Now int, to pacify GCC.
10409 (table_grow, table_ninf_remap): Use signed table size.
10410 (save_row): Don't bother initializing locals when not needed.
10411 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
10412 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
10414 * src/vcg.h: Correct misspellings.
10416 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
10419 * src/getargs.c (getargs): Don't assume EOF == -1.
10421 2002-12-09 Paul Eggert <eggert@twinsun.com>
10423 Change identifier spellings to avoid collisions with names
10424 that are reserved by POSIX.
10426 Don't use names ending in _t, since POSIX reserves them.
10427 For consistency, remove _e and _s endings -- they're weren't
10428 needed to remove ambiguity. All uses changed.
10429 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
10430 turn was just renamed from struniq_t.
10431 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
10432 which in turn was just renamed from struniq_processor_t.
10433 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
10434 in turn was renamed from hash_compare_struniq_t.
10435 * src/LR0.c (struct state_list): Renamed from struct state_list_s.
10436 (state_list): Renamed from state_list_t.
10437 * src/assoc.h (assoc): Renamed from assoc_t.
10438 * src/conflicts.c (enum conflict_resolution): Renamed from
10439 enum conflict_resolution_e.

10452 * src/location.h (location): Renamed from location_t.
10453 * src/muscle_tab.c (muscle_entry): Renamed from muscle_entry_t,
10454 and moved here from:
10455 * src/muscle_tab.h (muscle_entry_t): here.
10456 * src/nullable.c (struct rule_list): Renamed from struct rule_list_s.
10457 (rule_list): Renamed from rule_list_t.
10458 * src/print_graph.c (static_graph): Renamed from graph.

10502 Rename value_t -> value.
10503 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
10504 value_t_as_yystype -> value_as_yystype.
10506 Don't include <errno.h> in the mainstream code, since it
10507 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
10508 * lib/get-errno.c, lib/get-errno.h: New files.
10509 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
10511 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
10512 * src/output.c (output_skeleton): Likewise.
10513 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno

10519 (TAB_EXT): Renamed from EXT_TAB.
10520 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
10522 Avoid str[a-z]*, since <string.h> reserves that name space.
10523 Change all instances of "struniq" in names to "uniqstr", and
10524 likewise for "STRUNIQ" and "UNIQSTR".
10525 * src/uniqstr.c: Renamed from src/struniq.c.
10526 * src/uniqstr.h: Renamed from src/struniq.h.
10527 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
10528 * src/files.c (strsuffix): Remove; unused.
10529 (concat2): Renamed from stringappend. Now static.
10530 * src/files.h (strsuffix, stringappend): Remove; unused.
10531 * src/parse-gram.y (<chars>): Renamed from <string>.
10532 (<uniqstr>): Renamed from <struniq>.

10537 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
10538 (N_EXPAND): Renamed from N_STRETCH.

10541 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
10542 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
10544 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.

10548 (BASE_MAXIMUM): Renamed from BASE_MAX.
10549 (BASE_MINIMUM): Renamed from BASE_MIN.
10550 (ACTION_MAX): Remove; unused.
10551 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
10552 Unnecessary casts removed from above defines.
10555 Fix misspelling in names.
10556 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
10557 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
10561 * lib/timevar.c (timevar_report): Renamed from time_report,
10562 for consistency with other names.
10563 * lib/timevar.h (timevar_report): New decl.
10564 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
10567 Sort include-file uses.
10569 Reorder all include files under src to be in the order "system.h".
10570 then the ../lib include files in angle brackets (alphabetized),
10571 then the . include files in double-quotes (alphabetized). Fix
10572 dependency breakages encountered in this process, as follows:
10573 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
10574 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
10575 * src/state.h: Include "symtab.h".
10577 2002-12-08 Paul Eggert <eggert@twinsun.com>
10579 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
10580 since this causes problems when __file__ contains character
10581 sequences like "@" that are treated specially by src/scan-skel.l.
10582 Instead, just use the file's basename. This fixes the bug
10583 reported by Martin Mokrejs in
10584 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
10586 2002-12-06 Paul Eggert <eggert@twinsun.com>
10588 Add support for rules that do not have trailing semicolons, as
10589 POSIX requires. Improve the quality of locations in Bison
10592 * src/location.c: Include <quotearg.h>.
10593 (empty_location): Now const.
10594 (location_print): New function. Follow the recommendation of the
10595 GNU Coding Standards for locations that span file boundaries.
10596 * src/location.h: Do not include <quotearg.h>; no longer needed.
10597 (boundary): New type.
10598 (location_t): Use it. This allows locations to span file boundaries.
10599 All member uses changed: file -> start.file or end.file (as needed),
10600 first_line -> start.line, first_column -> start.column,
10601 last_line -> end.line, last_column -> end.column.
10602 (equal_boundaries): New function.
10603 (LOCATION_RESET, LOCATION_STEP): Remove.
10604 (LOCATION_PRINT): Remove. All callers changed to use location_print.
10605 (empty_location): Now const.
10606 (location_print): New decl.
10607 * src/parse-gram.y (lloc_default): New function, which handles
10608 empty locations more accurately.
10609 (YYLLOC_DEFAULT): Use it.
10610 (%token COLON): Remove.
10611 (%token ID_COLON): New token.
10613 (declarations, rules): Remove trailing semicolon.
10614 (declaration, rules_or_grammar_declaration):
10615 Allow empty (";") declaration.
10616 (symbol_def): Remove empty actions; no longer needed.
10617 (rules_or_grammar_declaration): Remove trailing semicolon.
10618 (semi_colon.opt): Remove.
10619 * src/reader.h: Include location.h.
10620 (scanner_cursor): New decl.
10621 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
10623 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
10625 (STEP): Remove. No longer needed, now that adjust_location does
10626 the work. All uses removed.
10627 (scanner_cursor): New var.
10628 (adjust_location): Renamed from extend_location. It now sets
10629 *loc and adjusts the scanner cursor. All uses changed.
10630 Don't bother testing for CR.
10631 (handle_syncline): Remove location arg; now updates scanner cursor.
10632 All callers changed.
10633 (unexpected_end_of_file): Now accepts start boundary of token or
10634 comment, not location. All callers changed. Update scanner cursor,
10636 (SC_AFTER_IDENTIFIER): New state.
10637 (context_state): Renamed from c_context. All uses changed.
10638 (id_loc, code_start, token_start): New local vars.
10639 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
10640 processing of Yacc white space and equivalents here.
10641 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
10642 instead of returning ID immediately, since we need to search for
10643 a subsequent colon.
10644 (<INITIAL>"'", "\""): Save token_start.
10645 (<INITIAL>"%{", "{", "%%"): Save code_start.
10646 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
10647 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
10648 BEGIN context_state at end, not INITIAL.
10649 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
10650 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
10651 Return correct token start.
10652 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
10653 the start of a character, string or multiline comment is found.
10654 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
10655 Reduction): Adjust reported locations to match the more-precise
10656 results now expected.
10657 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
10658 * tests/reduce.at (Useless Rules, Reduced Automaton,
10659 Underivable Rules): Likewise.
10660 * tests/regression.at (Invalid inputs): No longer `expecting ";"
10661 or "|"' now that so many other tokens are allowed by the new grammar.
10663 * src/complain.h (current_file): Remove duplicate decl;
10664 current_file is now owned by files.h.
10665 * src/complain.c, src/scan-gram.l: Include files.h.
10667 2002-12-06 Paul Eggert <eggert@twinsun.com>
10669 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
10670 promotes to int; it might be unsigned int.
10671 * data/yacc.c (yy_reduce_print): Likewise.
10673 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
10674 be #defined in the prologue, not in the Bison declarations.
10675 This fixes Debian Bug 102878, reported by Shaul Karl.
10677 2002-12-02 Paul Eggert <eggert@twinsun.com>
10679 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
10680 * lib/strtoul.c: New file, from gnulib.
10681 This fixes a porting bug reported by Peter Klein in
10682 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
10684 2002-11-30 Paul Eggert <eggert@twinsun.com>
10686 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
10687 and put only a forward declaration in the prologue. This is for
10688 consistency with the other scanner helper functions.
10690 Type clashes now generate warnings, not errors, since it
10691 appears that POSIX may allow some grammars with type clashes.
10692 * src/reader.c (grammar_current_rule_check): Warn about
10693 type clashes instead of complaining.
10694 * tests/input.at (Type Clashes): Expect warnings, not complaints.
10696 Add Yacc library, since POSIX requires it.
10697 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
10698 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
10699 * lib/main.c, lib/yyerror.c: New files.
10701 gram_error can be static; it need not be extern.
10702 * src/reader.h (gram_error): Remove decl.
10703 * src/parse-gram.y (gram_error): Now static. Add static decl.
10704 (print_token_value): Omit parameter names from forward decl,
10707 2002-11-29 Paul Eggert <eggert@twinsun.com>
10709 * doc/bison.texinfo: Emphasize that yylex and yyerror must
10710 be declared before being used. E.g., one should typically
10711 declare them in the prologue. Use GNU coding style in examples.
10712 Put "const" consistently after the type it modifies. Mention
10713 that C99 supports "inline". Mention that yyerror traditionally
10716 %parse-param and %lex-param now take just one argument, the
10717 declaration; the argument name is deduced from the declaration.
10719 * doc/bison.texinfo (Parser Function, Pure Calling, Error
10720 Reporting, Table of Symbols): Document this.
10721 * src/parse-gram.y (add_param): New function.
10723 (declaration): Implement new rule for %parse-param and %lex-param.
10724 * src/scan-gram.l: "," now elicits a warning, rather than being
10725 a token; this is more compatible with byacc.
10726 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
10728 2002-11-27 Paul Eggert <eggert@twinsun.com>
10730 Rename identifiers to avoid real and potential collisions.
10732 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
10733 to avoid collision with lex macro described by Bruce Lilly in
10734 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10735 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10736 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
10737 * src/parse-gram.y (print_token_value): Renamed from yyprint.
10739 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
10740 The name "yycontrol" violates the name space rules, and this stuff
10741 wasn't being used anyway.
10742 (input): Remove action; this stuff wasn't being used.
10743 (gram_error): Rename local variable yylloc -> loc.
10744 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
10745 (YY_DECL): Don't use "yy" at start of local variables.
10746 All uses changed, e.g., yylloc -> loc.
10747 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
10748 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
10749 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
10750 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
10752 * src/parse-gram.y (gram_error): loc is now const *.
10753 * src/reader.h (gram_error): Likewise.
10755 2002-11-24 Paul Eggert <eggert@twinsun.com>
10759 * tests/actions.at (Actions after errors): Use an output format
10760 more similar to that of the Printers and Destructors test.
10761 Test the position of the ';' token too.
10762 (Printers and Destructors): Likewise.
10763 (Printers and Destructors: %glr-parser): Remove for now, to avoid
10764 unnecessarily alarming people when the test fails.
10766 * data/yacc.c (yyerrlab1): Move this label down, so that the
10767 parser does not discard the lookahead token if the user code
10768 invokes YYERROR. This change is required for POSIX conformance.
10770 * lib/error.c: Sync with gnulib.
10772 2002-11-22 Paul Eggert <eggert@twinsun.com>
10774 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
10775 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
10776 * lib/xmalloc.c: Likewise.
10778 2002-11-20 Paul Eggert <eggert@twinsun.com>
10780 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
10782 2002-11-20 Paul Eggert <eggert@twinsun.com>
10784 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
10785 should use `if (! x) abort ();' rather than `assert (x);', and
10786 anyway it's one less thing to worry about configuring.
10788 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
10789 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
10790 and replace all instances of assert with abort.
10791 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
10792 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
10794 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
10795 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
10796 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
10797 hash_find_entry, hash_rehash, hash_insert): Likewise.
10798 * src/conflicts.c (resolve_sr_conflict): Likewise.
10799 * src/lalr.c (set_goto_map, map_goto): Likewise.
10800 * src/nullable.c (nullable_compute): Likewise.
10801 * src/output.c (prepare_rules, token_definitions_output): Likewise.
10802 * src/reader.c (packgram, reader): Likewise.
10803 * src/state.c (state_new, state_free, state_transitions_set,
10804 state_reduction_find): Likewise.
10805 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
10806 symbol_pack): Likewise.
10807 * src/tables.c (conflict_row, pack_vector): Likewise.
10808 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10809 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10810 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
10811 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
10813 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
10814 (ARGMATCH_CONSTRAINT): New macro.
10815 (ARGMATCH_ASSERT): Use it.
10817 * src/system.h (verify): New macro.
10818 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
10819 rather than assert.
10820 * src/tables.c (tables_generate): Likewise.
10822 * src/struniq.c (struniq_assert): Now returns void, and aborts
10823 if the assertion is false.
10824 (struniq_assert_p): Remove.
10825 * src/struniq.h: Likewise.
10827 2002-11-18 Paul Eggert <eggert@twinsun.com>
10829 * data/glr.c (yygetLRActions): Replace `yyindex' with
10830 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
10831 This fixes the regression with Sun ONE Studio 7 cc that I reported in
10832 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
10834 2002-11-18 Akim Demaille <akim@epita.fr>
10836 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
10838 From Tim Van Holder.
10840 2002-11-17 Paul Eggert <eggert@twinsun.com>
10842 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
10843 to "SyntaxError" for consistency with my 2002-11-15 change.
10845 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
10846 not define to {}, since this breaks the common use of `YYDPRINTF
10847 ((...));' if a single statement is desired (e.g. before `else').
10848 Work around GCC warnings by surrounding corresponding calls with
10850 (yyhasResolvedValue): Remove unused function.
10851 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
10853 (yyreportSyntaxError): Renamed from yyreportParseError.
10854 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
10856 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
10857 extern when possible. Remove unused initializations.
10859 2002-11-16 Akim Demaille <akim@epita.fr>
10861 Augment the similarity between GLR and LALR traces.
10863 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
10864 (YY_REDUCE_PRINT): New.
10865 (yyparse): Use them.
10866 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
10868 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
10869 state reached after the reduction/recovery, since...
10870 (yyparse, yyprocessOneStack): Report the state we are entering in.
10872 2002-11-16 Akim Demaille <akim@epita.fr>
10874 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
10875 Add support for --trace=skeleton.
10876 * src/scan-skel.l: %option debug.
10877 Scan strings of non-@ or \n instead of character by character.
10878 (scan_skel): Handle trace_skeleton.
10880 (@output_parser_name@, @output_header_name@): ``Restore'' their
10881 support (used to be M4 macros).
10882 * data/yacc.c: Quote larger chunks, a la glr.c.
10883 * data/lalr1.cc: Likewise.
10884 The header guards are no longer available, so use some other
10885 string than `YYLSP_NEEDED'.
10887 2002-11-16 Akim Demaille <akim@epita.fr>
10889 Make the ``Printers and Destructors'' test more verbose, taking
10890 `yacc.c''s behavior as (possibly wrong) reference.
10892 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
10893 instead of fprint on stdout.
10894 Set and report the last_line of the symbols.
10895 Consistently display values and locations.
10897 2002-11-16 Paul Eggert <eggert@twinsun.com>
10899 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
10901 2002-11-15 Paul Eggert <eggert@twinsun.com>
10903 * tests/actions.at (Actions after errors): New test case.
10905 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
10906 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
10907 tests/action.at, tests/calc.at, tests/conflicts.at,
10908 tests/cxx-type.at, tests/regression.at:
10909 "parse error" -> "syntax error" for POSIX compatibility.
10910 "parsing stack overflow..." -> "parser stack overflow" so
10911 that code matches Bison documentation.
10913 2002-11-15 Akim Demaille <akim@epita.fr>
10915 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
10916 take two BRACED_CODE, not two string_content.
10917 Free the scanner's obstack when we are done.
10918 (code_content): New.
10919 * tests/calc.at: Adjust.
10920 * doc/bison.texinfo: Adjust.
10921 Also, make sure to include the `,' for these declarations.
10923 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
10925 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
10926 definition; avoids potential autoreconf problems.
10928 2002-11-15 Akim Demaille <akim@epita.fr>
10930 Always check the value returned by yyparse.
10932 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
10933 returned by yyparse.
10934 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
10936 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
10937 returned by yyparse.
10939 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>

10944 2002-11-14 Paul Eggert <eggert@twinsun.com>
10946 * src/output.c (output_skeleton): Call xfopen instead of
10947 duplicating xfopen's body.
10949 Fix bugs reported by Nelson H. F. Beebe in
10950 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
10952 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
10953 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
10954 Group compiler. Instead, use "$CC -E bar.c". Include the .h
10955 file twice in the grammar, as an extra check.
10957 * tests/input.at (Torturing the Scanner): Surround the
10958 backslash-newline tests with "#if 0", to make it less likely that
10959 we'll run into compiler bugs. Bring back solitary \ inside
10960 comment, but add a closing comment to work around HP C bug. Don't
10961 test backslash-newline in C character constant.
10963 2002-11-14 Akim Demaille <akim@epita.fr>
10965 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
10966 status of the compiler.
10967 Calling `exit 1' is no longer needed.
10968 Reported by Nelson H. F. Beebe.
10970 2002-11-14 Akim Demaille <akim@epita.fr>
10972 * tests/atlocal.in (CPPFLAGS): We have config.h.
10973 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
10975 * tests/actions.at, tests/calc.at, tests/conflicts.at,
10976 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
10977 * tests/regression.at, tests/torture.at: Use them for all the
10978 grammars that are to be compiled.
10979 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
10980 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
10981 * doc/bison.texinfo (GLR Parsers): Document `inline'.
10983 2002-11-14 Akim Demaille <akim@epita.fr>
10985 * doc/bison.texinfo: Various formatting changes (alignments in
10986 samples, additional @group/@end group, GCS in samples.
10987 Use @deffn instead of simple @table to define the directives,
10988 macros, variables etc.
10990 2002-11-13 Paul Eggert <eggert@twinsun.com>
10992 Fix some bugs reported by Albert Chin-A-Young in
10993 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
10995 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
10996 -o c"; the HP C compiler chatters during compilation.
10997 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
10998 * tests/headers.at (export YYLTYPE): Likewise.
11000 * tests/input.at (Torturing the Scanner): Remove lines containing
11001 solitary backslashes, as they tickle a bug in the HP C compiler.
11003 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
11004 comments, since they're not portable. Use GNU coding style.
11006 2002-11-13 Akim Demaille <akim@epita.fr>
11008 * data/yacc.c: Leave bigger chunks of quoted text.
11009 (YYDSYMPRINTF): New.
11010 Use it to report symbol activities.

11018 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
11019 (yyglrReduce): Return yyok, not 0.
11020 This should avoid the enumerated-type warnings reported
11021 by Nelson H. F. Beebe in
11022 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
11024 * lib/bbitset.h (BITSET_INLINE): Remove.
11025 * lib/bitset.h [! BITSET_INLINE]: Remove.
11026 (bitset_set, bitset_reset, bitset_test): Rename local vars
11027 to avoid shadowing warnings by GCC.
11029 * data/glr.c (inline): Remove #define. It's the user's
11030 responsibility to #define it away, just like 'const'.
11031 This fixes one of the bugs reported by Nelson H. F. Beebe in
11032 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
11034 * Makefile.maint (po-check): Scan .l and .y files instead of the
11035 .c and the .h files that they generate. This fixes the bug
11036 reported by Tim Van Holder in:
11037 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
11038 Look for N_ as well as for _. Try to avoid matching #define for
11040 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
11041 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
11042 * src/scan-gram.l: Revamp regular expressions so that " and '
11043 do not confuse xgettext.
11045 * src/struniq.h (struniq_new): Do not declare the return type
11046 to be 'const'; this violates the C standard.
11047 * src/struniq.c (struniq_new): Likewise.
11049 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
11051 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
11052 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
11055 2002-11-12 Akim Demaille <akim@epita.fr>
11057 * Makefile.maint: Sync with Autoconf:
11058 (local_updates): New.
11060 2002-11-12 Akim Demaille <akim@epita.fr>
11062 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
11064 2002-11-12 Akim Demaille <akim@epita.fr>

11074 2002-11-12 Akim Demaille <akim@epita.fr>
11076 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
11077 Use it to test the GLR parser.
11079 2002-11-12 Akim Demaille <akim@epita.fr>
11081 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
11083 * data/glr.c (yystos): New.
11084 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
11085 (YYDSYMPRINT): New.
11086 (yyval): Don't define it, it is handled via M4.
11087 (yyrecoverParseError): Free verbosely the discarded symbols.
11088 * data/yacc.c (yysymprint): Remove, rather...
11089 (b4_yysymprint_generate): invoke.
11090 * data/c.m4 (b4_yysymprint_generate): New.
11091 Accept pointers as arguments, as opposed to the version from
11093 (b4_yydestruct_generate): Likewise.
11094 * tests/cations.at (Printers and Destructors): Use Bison directives
11095 instead of CPP macros.
11096 Don't rely on internal details.
11098 2002-11-12 Akim Demaille <akim@epita.fr>
11100 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
11101 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
11102 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
11103 it against YYEMPTY and so forth), work on yytoken (i.e., set
11104 it to YYEMPTY etc.).
11105 (yydestruct): Replace with a b4_yydestruct_generate invocation.
11106 (b4_symbol_actions): Remove.
11107 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
11108 for 0, end-of-input.
11110 2002-11-12 Akim Demaille <akim@epita.fr>
11112 * doc/bison.texinfo (Destructor Decl): New.
11114 2002-11-12 Akim Demaille <akim@epita.fr>
11116 * src/tables.c (tables_generate): Use free for pointers that
11117 cannot be NULL, not XFREE.
11118 (pack_vector): Use assert, not fatal, for bound violations.
11119 * src/state.c (state_new): Likewise.
11120 * src/reader.c (reader): Likewise.
11121 * src/lalr.c (set_goto_map): Likewise.
11122 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
11125 2002-11-12 Akim Demaille <akim@epita.fr>
11127 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
11129 * src/scan-gram.l (last_string): Is global to the file, not to
11131 * src/parse-gram.y (input): Don't append the epilogue here,
11132 (epilogue.opt): do it here, and free the scanner's obstack.
11133 * src/reader.c (epilogue_set): Rename as...
11134 (epilogue_augment): this.
11135 * data/c.m4 (b4_epilogue): Defaults to empty.

11147 * src/struniq.h, src/struniq.c (struniq_t): Is const.
11148 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
11150 Use struniq for symbols.
11152 * src/symtab.h (symbol_t): The tag member is a struniq.

11163 and type members are struniqs.
11164 * src/reader.c (get_merge_function)
11165 (grammar_current_rule_merge_set): Adjust.
11166 (TYPE, current_type): Are struniq.
11168 Use struniq for file names.
11170 * src/files.h, src/files.c (infile): Split into...
11171 (grammar_file, current_file): these.
11172 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.

11193 2002-11-11 Paul Eggert <eggert@twinsun.com>
11195 Revamp to fix many (but not all) of the C- and M4-related quoting
11196 problems. Among other things, this fixes the Bison bug reported
11197 by Jan Hubicka when processing the Bash grammar; see:
11198 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
11200 Use new @ escapes consistently. Represent brackets with @{ and @}
11201 rather than @<:@ and @:>@, since this works a bit better with dumb
11202 editors like vi. Represent @ with @@, since @ is now consistently
11203 an escape. Use @oline@ and @ofile@ rather than __oline__ and
11204 __ofile__, to avoid unexpected expansions. Similarly, use @output
11205 rather than #output.
11207 * data/c.m4 (b4_copyright): Omit file name from comment, since
11208 the file name could contain "*/".
11209 (b4_synclines_flag): Don't quote the 2nd argument; it should already
11210 be quoted. All uses changed.
11212 * data/glr.c: Use new @ escapes consistently.
11213 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
11214 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
11215 Remove, since they couldn't handle arbitrary characters in file
11217 * data/lalr1.cc: Likewise.
11218 * data/yacc.c: Likewise.
11220 * src/files.c (output_infix): Remove; all uses removed.
11221 * src/files.h: Likewise.
11223 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
11224 mishandled funny characters in file names, and anyway it isn't
11226 * data/yacc.c: Likewise.
11227 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
11229 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
11230 * data/yacc.c: Likewise.
11232 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
11234 (muscle_init): Quote filename as a C string.
11235 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
11236 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
11237 * src/output.c (escaped_file_name_output): New function.
11238 (prepare_symbols): Quote tokens for M4.
11239 (prepare): Don't insert output_infix, output_prefix,
11240 output_parser_name, output_header_name; this is now down by scan-skel.
11241 Insert skeleton as a C string.
11243 * src/output.c (user_actions_output, symbol_destructors_output,
11244 symbol_printers_output): Quote filenames for C and M4.
11245 * src/reader.c (prologue_augment, epilogue_set): Likewise.
11247 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
11248 escapes other than \\ and \'; this simplifies the code.
11249 (<SC_STRING>): Likewise, for \\ and \".
11250 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
11251 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
11252 Use new escapes @{ and @} for [ and ].
11254 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11255 them with auto vars.
11256 Switch to new escape scheme, where @ is the escape character uniformly.
11257 Abort if a stray escape character is found. Avoid unbounded input
11258 buffer when parsing non-escaped text.
11260 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
11261 __oline__, #output, $@, and @{ do not have unintended meanings.
11263 2002-11-09 Paul Eggert <eggert@twinsun.com>
11265 Fix the test failure due to GCC warnings described in
11266 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
11267 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
11268 evaluate to 0 if it's impossible for NINF to be in the respective
11270 (yygetLRActions, yyrecoverParseError): Use them.
11272 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
11273 counted in the token inserted at end of file. Now takes
11274 location_t *, not location_t, so that the location can be
11275 adjusted. All uses changed.
11277 * tests/regression.at (Invalid inputs): Adjust wording in
11278 diagnostic to match the new behavior.
11280 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
11281 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
11282 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
11283 abort ();'. This reduces the runtime of the "Many lookaheads"
11284 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
11287 2002-11-07 Paul Eggert <eggert@twinsun.com>
11289 * src/parse-gram.y (CHARACTER): Remove unused token.
11292 * src/scan-gram.l: Remove stack option. We no longer use the
11293 stack, since the stack was never deeper than 1; instead, use the
11294 new auto var c_context to record the stacked value.
11296 Remove nounput option. At an unexpected end of file, we now unput
11297 the minimal input necessary to end cleanly; this simplifies the
11300 Avoid unbounded token sizes where this is easy.
11302 (unexpected_end_of_file): New function.
11303 Use it to systematize the error message on unexpected EOF.
11304 (last-string): Now auto, not static.
11305 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
11306 (scanner_last_string_free): Remove; not used.
11307 (percent_percent_count): Move decl to just before use.
11308 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
11309 not the (never otherwised-used) CHARACTER.
11311 2002-11-07 Akim Demaille <akim@epita.fr>
11313 Let yyerror always receive the msg as last argument, so that
11314 yyerror can be variadic.
11316 * data/yacc.c (b4_yyerror_args): New.
11317 Use it when calling yyerror.
11318 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
11319 Use it when calling yyerror.

11324 2002-11-06 Akim Demaille <akim@epita.fr>
11326 #line should have quoted strings.
11327 Ideally, this should be done by m4_quotearg.
11329 * src/scan-skel.l: Include quotearg.h.
11331 * src/output.c (symbol_printers_output)
11332 (symbol_destructors_output): Quote the file name.
11334 2002-11-06 Akim Demaille <akim@epita.fr>

11339 2002-11-06 Akim Demaille <akim@epita.fr>
11341 Restore --no-lines.
11342 Reported by Jim Kent.
11344 * data/c.m4 (b4_syncline): New.
11345 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
11346 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
11347 * src/output.c (user_actions_output): Likewise.
11348 (prepare): Define 'b4_synclines_flag'.
11349 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
11351 2002-11-06 Akim Demaille <akim@epita.fr>
11353 * src/main.c (main): Free `infile'.
11354 * src/scan-gram.l (handle_syncline): New.

11366 2002-11-05 Paul Eggert <eggert@twinsun.com>
11368 * src/scan-gram.l: Use more accurate diagnostics, e.g.
11369 "integer out of range" rather than "invalid value".
11370 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
11373 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
11374 Also, remove one static variable in the scanner.
11376 * src/scan-gram.l (braces_level): Now auto, not static.
11377 Initialize to zero if the compiler is being picky.
11378 (INITIAL): Clear braces_level instead of incrementing it.

11382 * configure.ac: Define "lint" if --enable-gcc-warnings.
11384 2002-11-05 Akim Demaille <akim@epita.fr>
11386 * src/scan-gram.l: When it starts with `%', complain about the
11387 whole directive, not just that `invalid character: %'.
11389 2002-11-04 Akim Demaille <akim@epita.fr>
11391 * Makefile.maint: Update from Autoconf.
11392 (update, cvs-update, po-update, do-po-update): New.

11401 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
11403 2002-11-04 Akim Demaille <akim@epita.fr>
11405 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid

11410 Use quote, not quote_n since LOCATION_PRINT no longer uses the
11413 2002-11-03 Paul Eggert <eggert@twinsun.com>
11415 * src/reader.c (get_merge_function, grammar_current_rule_check):
11416 Use consistent diagnostics for reporting type name clashes.
11417 Quote the types with <>, for consistency with Yacc.
11418 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
11420 2002-11-03 Akim Demaille <akim@epita.fr>
11422 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
11424 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.

11431 Use b4_identification.
11432 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
11433 b4_user_formals and b4_user_args.
11434 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
11435 (yyreportAmbiguity): When using a pure parser, also need
11436 the location, and the parse-params.
11438 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
11439 When using a pure parser, also need the parse-params.
11441 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
11442 (%pure-parser + %parse-param) LALR and GLR parsers.
11443 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
11444 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
11445 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
11446 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
11447 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
11448 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
11449 * doc/bison.texinfo: Untabify the whole file.
11450 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
11451 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
11452 (Error Reporting): Adjust to these new directives.
11453 Document %error-verbose, deprecate YYERROR_VERBOSE.
11455 2002-11-03 Akim Demaille <akim@epita.fr>
11457 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
11458 AT_CHECK_CALC_GLR invocations to use % directives, instead of
11459 command line options.
11460 * tests/cxx-type.at: Formatting changes.
11462 2002-11-03 Paul Eggert <eggert@twinsun.com>
11464 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
11465 to count columns correctly, and to check for invalid inputs.
11467 Use mbsnwidth to count columns correctly. Account for tabs, too.
11468 Include mbswidth.h.
11469 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
11470 (extend_location): New function.
11471 (YY_LINES): Remove.
11473 Handle CRLF in C code rather than in Lex code.

11475 (no_cr_read): New function.
11477 Scan UCNs, even though we don't fully handle them yet.

11480 Handle backslash-newline correctly in C code.
11481 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
11482 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
11484 (tag, splice): New EREs. Do not allow NUL or newline in tags.
11485 Use {splice} wherever C allows backslash-newline.
11486 YY_STEP after space, newline, vertical-tab.
11487 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
11489 (letter, id): Don't assume ASCII; e.g., spell out a-z.
11491 ({int}, handle_action_dollar, handle_action_at): Check for integer
11494 (YY_STEP): Omit trailing semicolon, so that it's more like C.
11496 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
11497 as well as \000. Check for UCHAR_MAX, not 255.
11498 Allow \x with an arbitrary positive number of digits, as in C.
11499 Check for overflow here.
11500 Allow \? and UCNs, for compatibility with C.
11502 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
11503 with quote slot used by complain_at.
11505 * tests/input.at: Add tests for backslash-newline, m4 quotes
11506 in symbols, long literals, and funny escapes in strings.
11508 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
11509 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

11512 * m4/mbswidth.m4: New file, from GNU coreutils.
11514 * doc/bison.texinfo (Grammar Outline): Document // comments.
11515 (Symbols): Document that trigraphs have no special meaning in Bison,
11516 nor is backslash-newline allowed.
11517 (Actions): Document that trigraphs have no special meaning.

11522 2002-11-02 Paul Eggert <eggert@twinsun.com>
11524 * src/reader.c: Don't include quote.h; not needed.
11525 (get_merge_function): Reword warning to be consistent with
11526 type clash diagnostic in grammar_current_rule_check.
11528 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
11529 bug in trigraph handling.
11531 * src/output.c (prepare_symbols): When printing token names,
11532 escape "[" as "@<:@" and likewise for "]".
11534 * src/system.h (errno): Remove declaration, as we are now
11535 assuming C89 or better, and C89 guarantees errno.
11537 2002-10-30 Paul Eggert <eggert@twinsun.com>
11539 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
11540 Check for close failures.
11541 * src/files.h (xfclose): Return void, not int, since it always
11543 * src/files.c (xfclose): Likewise. Report I/O error if ferror
11545 * src/output.c (output_skeleton): Use xfclose rather than fclose
11546 and ferror. xfclose now checks ferror.
11548 * data/glr.c (YYLEFTMOST_STATE): Remove.
11549 (yyreportTree): Use a stack-based leftmost state. This avoids
11550 our continuing battles with bogus warnings about initializers.
11552 2002-10-30 Akim Demaille <akim@epita.fr>
11554 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
11557 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11559 * tests/glr-regr1.at: New test for reported regressions.
11560 * tests/testsuite.at: Add glr-regr1.at test.
11561 * tests/Makefile.am: Add glr-regr1.at test.

11567 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
11568 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
11569 we use malloc. Don't assume 'A' through 'Z' are contiguous.
11570 Don't assume strdup exists; POSIX says its an XSI extension.
11571 Check for buffer overflow on input.
11573 2002-10-24 Akim Demaille <akim@epita.fr>
11575 * src/output.c (output_skeleton): Don't disable M4sugar comments
11576 too soon: it results in comments being expanded.
11577 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
11580 2002-10-24 Akim Demaille <akim@epita.fr>
11582 * data/yacc.c (m4_int_type): New.
11583 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
11584 char' as only yacc.c wants K&R portability.
11585 * data/glr.c (yysigned_char): Remove.
11586 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
11587 Reported by Quoc Peyrot.
11589 2002-10-23 Paul Eggert <eggert@twinsun.com>
11591 * src/main.c (main): With --trace=time, report times even if a
11592 non-fatal error occurs. Formerly, the times were reported in some
11593 such cases but not in others.
11594 * src/reader.c (reader): Just return if a complaint has been issued,
11595 instead of exiting, so that 'main' can report times.
11597 2002-10-22 Akim Demaille <akim@epita.fr>
11599 * src/system.h: Include sys/types.
11600 Reported by Bert Deknuydt.
11602 2002-10-23 Paul Eggert <eggert@twinsun.com>
11604 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
11605 Suggested by Art Haas.
11607 2002-10-22 Paul Eggert <eggert@twinsun.com>
11609 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
11610 decl; not needed any more.
11611 * src/main.c (main): Use return to exit, undoing yesterday's change.
11612 The last OS that we could find where this wouldn't work is
11613 SunOS 3.5, and that's too old to worry about now.
11615 * data/glr.c (struct yyltype): Define members even when not
11616 doing locations. This is more consistent with yacc.c, and it
11617 works around the following bug reports:
11618 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
11619 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
11621 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
11622 @acronym consistently. Standardize on "Yacc" instead of "YACC",
11623 "Algol" instead of "ALGOL". Give a bit more history about BNF.
11625 2002-10-22 Akim Demaille <akim@epita.fr>
11627 * data/README: New.
11629 2002-10-21 Paul Eggert <eggert@twinsun.com>
11631 Be consistent about 'bool'; the old code used an enum in one
11632 module and an int in another, and this violates the C standard.
11633 * m4/stdbool.m4: New file, from coreutils 4.5.3.
11634 * configure.ac (AC_HEADER_STDBOOL): Add.
11635 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
11636 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
11637 * src/symtab.c (hash_compare_symbol_t): Likewise.
11638 * src/system.h (bool, false, true): Use a definition consistent
11639 with ../lib/hash.c. All uses changed.
11641 * src/complain.c (warning_issued): Renamed from warn_message_count,
11642 so that we needn't worry about integer overflow (!).
11643 Now of type bool. All uses changed.
11644 (complaint_issued): Renamed from complain_message_count; likewise.
11646 * src/main.c (main): Use exit to exit with failure.
11648 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
11649 rather than 1 and 0.
11650 * src/main.c (main): Likewise.
11651 * src/getargs.c (getargs): Likewise.
11652 * src/reader.c (reader): Likewise.
11654 * src/getarg.c (getargs): Remove duplicate code for
11655 "Try `bison --help'".
11657 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
11658 What was that "2" for?
11660 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
11661 * src/getargs.c (usage): Likewise.
11663 * src/getargs.c (getargs): When there are too few operands, report
11664 the last one. When there are too many, report the first extra
11665 one. This is how diffutils does it.
11667 2002-10-20 Paul Eggert <eggert@twinsun.com>
11669 Remove K&R vestiges.
11670 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
11671 * src/complain.c (VA_START): Remove. Assume prototypes.
11672 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
11673 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
11674 fatal): Assume prototypes.
11675 * src/complain.h: Assume prototypes.
11676 * src/system.h (PARAMS): Remove.
11677 Include <limits.h> unconditionally, since it's guaranteeed even
11678 for a freestanding C89 compiler.
11679 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
11680 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
11682 2002-10-20 Akim Demaille <akim@epita.fr>
11684 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.

11686 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
11687 (yyresolveStates, yyresolveAction, yyresolveStack)
11688 (yyprocessOneStack): Use them.
11689 (yy_reduce_print): New.
11690 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
11692 2002-10-20 Akim Demaille <akim@epita.fr>
11694 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
11695 arguments and output `void'.
11696 (b4_c_function): Rename as...
11697 (b4_c_function_def): this.
11698 (b4_c_function_decl, b4_c_ansi_function_def)
11699 (b4_c_ansi_function_decl): New.
11700 Change the interpretation of the arguments: before `int, foo', now
11702 * data/yacc.c (yyparse): Prototype and define thanks to these.
11703 Adjust b4_c_function_def uses.
11704 * data/glr.c (yyparse): Likewise, but ANSI only.
11706 2002-10-20 Akim Demaille <akim@epita.fr>
11708 * src/output.c (prepare): Move the definition of `tokens_number',
11709 `nterms_number', `undef_token_number', `user_token_number_max'
11711 (prepare_tokens): Here.
11712 (prepare_tokens): Rename as...
11713 (prepare_symbols): this.
11714 (prepare): Move the definition of `rules_number' to...
11715 (prepare_rules): here.
11716 (prepare): Move the definition of `last', `final_state_number',
11717 `states_number' to...
11718 (prepare_states): here.
11719 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
11721 2002-10-20 Akim Demaille <akim@epita.fr>
11723 * src/tables.h, src/tables.c, src/output.c: Comment changes.
11725 2002-10-20 Akim Demaille <akim@epita.fr>
11727 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
11730 2002-10-20 Akim Demaille <akim@epita.fr>
11732 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
11733 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
11735 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
11737 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
11738 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
11741 2002-10-19 Paul Eggert <eggert@twinsun.com>
11743 Do not create a temporary file, as that involves security and
11744 cleanup headaches. Instead, use a pair of pipes.
11745 Derived from a suggestion by Florian Krohm.
11746 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
11747 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
11748 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
11749 (BISON_PREREQ_SUBPIPE): Add.
11750 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
11751 Add subpipe.h, subpipe.c.

11759 Check for pipe I/O error.
11760 * src/scan-skel.l (readpipe): Remove decl.
11761 (scan_skel): New function, to be used in place of m4_invoke.
11762 Read from stream rather than file.
11764 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
11765 float, as this generates a warning on Solaris 8 + GCC 3.2 with
11766 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
11767 this generates a more-accurate value anyway.
11769 * lib/timevar.c (timervar_accumulate): Rename locals to
11770 avoid confusion with similarly-named more-global.
11771 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
11773 * src/output.c (prepare): Use xstrdup to convert char const *
11774 to char *, to avoid GCC warning.
11776 2002-10-19 Akim Demaille <akim@epita.fr>
11778 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
11779 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
11780 Use them to have `calc.y' ready for %pure-parser.
11781 * data/yacc.c (YYLEX): Pass a yylex return type to
11782 b4_c_function_call.
11784 2002-10-19 Akim Demaille <akim@epita.fr>
11786 Prototype support of %lex-param and %parse-param.
11788 * src/parse-gram.y: Add the definition of the %lex-param and
11789 %parse-param tokens, plus their rules.

11801 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
11802 (muscle_pair_list_grow): New.
11803 * data/c.m4 (b4_c_function_call, b4_c_args): New.

11810 * src/getargs.c (usage): Take status as argument and exit
11812 Report the traditional `Try ... --help' message when status != 0.
11813 (usage, version): Don't take a FILE * as arg, it is pointless.
11814 (getargs): When there is an incorrect number of arguments, make it
11815 an error, and report it GNUlically thanks to `usage ()'.
11817 2002-10-18 Paul Eggert <eggert@twinsun.com>
11819 * data/glr.c (yyreportParseError): Don't assume that sprintf
11820 yields the length of the printed string, as this is not true
11821 on SunOS 4.1.4. Reported by Peter Klein.
11823 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
11824 * tests/conflicts.at (%nonassoc and eof): Likewise.
11825 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
11827 2002-10-17 Akim Demaille <akim@epita.fr>
11829 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
11830 * src/getargs.c (trace_types, trace_args): Adjust.
11831 * src/reader.c (grammar_current_rule_prec_set)
11832 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
11833 Standardize error messages.
11834 And s/@prec/%prec/!
11835 (reader): Use trace_flag to enable scanner/parser debugging,
11836 instead of an adhoc scheme.
11837 * src/scan-gram.l: Remove trailing debugging code.
11839 2002-10-16 Paul Eggert <eggert@twinsun.com>
11841 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
11844 * NEWS: Officially drop support for building Bison with K&R C,
11845 since it didn't work anyway and it's not worth worrying about.
11846 * Makefile.maint (wget_files): Remove ansi2knr.c.
11847 (ansi2knr.c-url_prefix): Remove.
11848 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
11849 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11850 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11852 2002-10-15 Paul Eggert <eggert@twinsun.com>
11854 Stop using the "enum_" trick for K&R-style function definitions;
11855 it confused me, and I was the author! Instead, assume that people
11856 who want to use K&R C compilers (when using these modules in GCC,
11857 perhaps?) will run ansi2knr.
11859 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
11860 All uses of "enum_" changed to "enum ".

11872 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):

11874 static functions simply to provide their prototypes.

11943 * src/tables.c (table_ninf_remap): base -> tab.
11944 Reported by Matt Rosing.
11946 2002-10-14 Paul Eggert <eggert@twinsun.com>
11948 * tests/action.at, tests/calc.at, tests/conflicts.at,
11949 tests/cxx-type.at, tests/headers.at, tests/input.at,
11950 tests/regression.at, tests/synclines.at, tests/torture.at:
11951 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
11952 so that the tests still work even if POSIXLY_CORRECT is set.
11953 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
11955 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
11956 for portability to K&R hosts. Fix typo: signed char is guaranteed
11957 only to 127, not to 128.
11958 * data/glr.c (yysigned_char): New type.
11959 * data/yacc.c (yysigned_char): Likewise.
11960 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
11962 2002-10-13 Paul Eggert <eggert@twinsun.com>
11964 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
11965 true due to limited range of data type" warning from GCC.
11967 * data/c.m4 (b4_token_defines): Protect against double-inclusion
11968 by wrapping enum yytokentype's definition inside #ifndef
11969 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
11971 2002-10-13 Akim Demaille <akim@epita.fr>
11973 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
11974 Un yy- yyrhs to avoid the name clash with the global YYRHS.
11976 2002-10-13 Akim Demaille <akim@epita.fr>
11978 * Makefile.maint: Update from Autoconf 2.54.
11979 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
11981 2002-10-13 Akim Demaille <akim@epita.fr>
11983 * src/print.c (print_state): Separate the list of solved conflicts
11984 from the other items.
11985 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
11987 2002-10-13 Akim Demaille <akim@epita.fr>
11989 Let nondeterministic skeletons be usable with deterministic
11992 With the patch, GAWK compiled by GCC without -O2 passes its test
11993 suite using a GLR parser driven by LALR tables. It fails with -O2
11994 because `struct stat' gives two different answers on my machine:
11995 88 (definition of an auto var) and later 96 (memset on this var).
11996 Hence the stack is badly corrumpted. The headers inclusion is to
11997 blame: if I move the awk.h inclusion before GLR's system header
11998 inclusion, the two struct stat have the same size.
12000 * src/tables.c (pack_table): Always create conflict_table.
12001 (token_actions): Always create conflict_list.
12002 * data/glr.c (YYFLAG): Remove, unused.
12004 2002-10-13 Akim Demaille <akim@epita.fr>
12006 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
12008 (VALGRIND, GXX): New.
12009 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
12010 * tests/bison.in: Run $PREBISON a pre-command.
12011 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
12012 (maintainer-check-g++): New.

12015 2002-10-13 Akim Demaille <akim@epita.fr>
12017 * data/glr.c: Formatting changes.
12018 Tweak some trace messages to match yacc.c's.
12020 2002-10-13 Akim Demaille <akim@epita.fr>
12022 GLR parsers sometimes raise parse errors instead of performing the
12024 Reported by Charles-Henry de Boysson.
12026 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
12027 check the length of the traces when %glr.
12028 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
12030 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
12032 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
12033 (yyltype): Remove the yy prefix from the member names.
12034 (yytable): Complete its comment.
12035 (yygetLRActions): Map error action number from YYTABLE from
12037 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
12038 (which was a bug: it should have been YYTABEL_NINF, and yet it was
12039 not satisfying as we could compare an YYACTION computed from
12040 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
12041 only value for error actions.
12042 (yyreportParseError): In verbose parse error messages, don't issue
12043 `error' in the list of expected tokens.
12044 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
12045 next action to perform to match glr.c's decoding.
12046 (yytable): Complete its comment.

12050 Fix problem reported by Henrik Grubbstroem in
12051 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
12052 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12053 because the Bison parser reads the second action before reducing
12055 * src/scan-gram.l (rule_length): New static var.
12056 Use it to keep track of the rule length in the scanner, since
12057 we can't expect the parser to be in lock-step sync with the scanner.
12058 (handle_action_dollar, handle_action_at): Use this var.
12059 * tests/actions.at (Exotic Dollars): Test for the problem.
12061 2002-10-12 Paul Eggert <eggert@twinsun.com>
12063 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
12064 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
12065 Include <sys/time.h> when checking for clock_t and struct tms.
12066 Use same include order as source.
12067 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
12068 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
12070 * lib/timevar.c: Update copyright date and clarify comments.
12071 (get_time) [IN_GCC]: Keep the GCC version for reference.
12073 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
12074 GCC version as of today, then merge Bison's changes.
12075 Change "GCC" to "Bison" in copyright notice. timevar.def's
12076 author is Akim, so change that too.
12078 * src/reader.c (grammar_current_rule_check):
12079 Don't worry about the default action if $$ is untyped.
12080 Prevents bogus warnings reported by Jim Gifford in
12081 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
12083 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
12084 * data/glr.c, data/lalr1.cc, data/yacc.c:
12085 Output token definitions before the first part of user declarations.
12086 Fixes compatibility problem reported by Jim Gifford for kbd in
12087 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.

12091 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
12092 (yyparse): here. This undoes some of the 2002-07-25 change.
12093 Compatibility problem reported by Ralf S. Engelschall with
12094 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

12113 * lib/lbitset.c: Likewise.
12115 * lib/abitset.c (abitset_bytes): Return a size that is aligned
12116 properly for vectors of objects. Do not assume that adding a

12118 properly aligned for the whole union.

12161 Do not use "struct bitset_struct" to mean different things in
12162 different modules. Not only is this confusing, it violates
12163 the C Standard, which requires that structure types in different

12571 (handle_action_dollar, handle_action_at): Don't use isdigit,
12572 as it mishandles negative chars and it may not work as expected
12573 outside the C locale.
12575 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
12576 this is a GCC extension and is not portable to other compilers.

12815 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
12816 for the time being: %locations ought to provide it to yyerror.

14795 * data/bison.c++, data/bison.simple: Don't output the current file

15081 Move the filling of `skeleton' and its muscle to...
15083 (output): Move the definition of the prologue muscle to...
15085 * src/system.h (DEFAULT_TMPDIR): New.
15087 2002-02-14 Paul Eggert <eggert@twinsun.com>
15089 Remove the support for C++ namespace cleanliness; it was
15090 causing more problems than it was curing, since it didn't work
15091 properly on some nonstandard C++ compilers. This can wait
15092 for a proper C++ parser.
15094 * NEWS: Document this.
15095 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
15096 of C++, as it's treated like C now.
15097 * src/bison.simple (YYSTD): Remove.
15098 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
15099 Treat C++ just like Standard C instead of trying to support
15100 namespace cleanliness.
15102 2002-02-14 Akim Demaille <akim@epita.fr>
15104 * tests/regression.at (else): Adjust to Andreas' change.
15106 2002-02-14 Akim Demaille <akim@epita.fr>
15108 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
15110 2002-02-13 Andreas Schwab <schwab@suse.de>
15112 * src/output.c (output_rule_data): Don't output NULL, it might
15113 not be defined yet.
15115 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
15117 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
15118 (Copyright notice): Update.
15120 2002-02-11 Akim Demaille <akim@epita.fr>
15122 * tests/regression.at (%nonassoc and eof): Don't include
15123 nonportable headers.
15125 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
15127 * data/bison.c++: Correct error recovery. Make the user able to
15128 initialize the starting location.
15130 2002-02-07 Akim Demaille <akim@epita.fr>
15132 * tests/input.at: New.
15134 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15136 * data/bison.c++: Replace some direct m4 expansions by constants. Be
15137 more consistent when naming methods and variables. Put preprocessor
15138 directives around tables only needed for debugging.
15140 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15142 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
15144 (yy::b4_name::parse): Use print_.
15146 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15148 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
15150 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15152 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
15154 (yy::b4_name::parse): Build verbose error messages, and use error_.
15156 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
15158 * data/bison.c++: Fix m4 quoting in comments.
15160 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
15162 * data/bison.c++: Adjust the parser code. Fix some muscles that were
15163 not expanded by m4.
15165 2002-02-05 Akim Demaille <akim@epita.fr>
15167 * data/bison.c++: Adjust to the M4 back end.
15168 More is certainly needed.
15170 2002-02-05 Akim Demaille <akim@epita.fr>
15172 Give a try to M4 as a back end.
15174 * lib/readpipe.c: New, from wdiff.
15175 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
15177 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
15178 specific values. Now it is m4 that performs the lookup.
15179 * src/parse-skel.y: Remove.
15180 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
15181 * src/output.c (actions_output, guards_output)
15182 (token_definitions_output): No longer keeps track of the output
15183 line number, hence remove the second argument.
15184 (guards_output): Check against the guard member of a rule, not the
15187 (output_skeleton): Don't look for the skeleton location, let m4 do
15189 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
15191 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
15192 (prepare): Given that for the time being changesyntax is not
15193 usable in M4, rename the muscles using `-' to `_'.
15194 Define `defines_flag', `output_parser_name' and `output_header_name'.
15195 * src/output.h (actions_output, guards_output)
15196 (token_definitions_output): Adjust prototypes.
15197 * src/scan-skel.l: Instead of scanning the skeletons, it now
15198 processes the output of m4: `__oline__' and `#output'.
15199 * data/bison.simple: Adjust to be used by M4(sugar).
15200 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
15202 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
15203 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
15204 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
15205 shamelessly stolen from CVS Autoconf.
15207 2002-02-05 Akim Demaille <akim@epita.fr>
15209 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
15210 * configure.in: Check for the declarations of free and malloc.
15211 * src/muscle_tab.c: Adjust.
15213 2002-02-05 Akim Demaille <akim@epita.fr>
15215 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
15216 which have no values.
15218 2002-02-05 Akim Demaille <akim@epita.fr>
15220 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
15223 2002-01-29 Paul Eggert <eggert@twinsun.com>
15225 * src/bison.simple (YYSIZE_T): Do not define merely because
15226 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
15227 On some platforms, <alloca.h> does not declare YYSTD (size_t).
15229 2002-01-27 Akim Demaille <akim@epita.fr>
15231 Fix `%nonassoc and eof'.
15233 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
15234 which were not properly copied! Replace
15235 memcpy (res->errs, src->errs, src->nerrs);
15237 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
15239 * tests/regression.at (%nonassoc and eof): Adjust to newest
15240 Autotest: `.' is not in the PATH.
15242 2002-01-27 Akim Demaille <akim@epita.fr>
15244 * tests/sets.at (AT_EXTRACT_SETS): New.
15245 (Nullable): Use it.
15248 2002-01-26 Akim Demaille <akim@epita.fr>
15250 * tests/actions.at, tests/calc.at, tests/headers.at,
15251 * tests/torture.at: Adjust to the newest Autotest which no longer
15252 forces `.' in the PATH.
15254 2002-01-25 Akim Demaille <akim@epita.fr>
15256 * tests/regression.at (%nonassoc and eof): New.
15257 Suggested by Robert Anisko.
15259 2002-01-24 Akim Demaille <akim@epita.fr>
15261 Bison dumps core when trying to complain about broken input files.
15262 Reported by Cris van Pelt.
15264 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
15265 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
15267 (Invalid inputs): Strengthen: exercise parse_percent_token.
15269 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
15271 * src/Makefile.am: Add bison.c++.
15272 * src/bison.c++: New skeleton.
15274 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
15278 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
15280 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
15282 2002-01-20 Marc Autret <marc@gnu.org>
15284 * src/files.c (compute_output_file_names): Fix
15286 2002-01-20 Marc Autret <marc@gnu.org>
15288 * tests/output.at: New test.
15289 * src/files.c (compute_base_names): Don't map extensions when
15290 the YACC flag is set, use defaults.
15291 Reported by Evgeny Stambulchik.
15293 2002-01-20 Marc Autret <marc@gnu.org>
15295 * src/system.h: Need to define __attribute__ away for non-GCC
15296 compilers as well (i.e., the vendor C compiler).
15297 Suggested by Albert Chin-A-Young.
15299 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
15301 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
15302 canonical definition.
15303 * src/system.h: Use the canonical definition for PARAMS (avoids
15304 a conflict with the macro from lib/hash.h).
15306 2002-01-11 Akim Demaille <akim@epita.fr>
15308 * configure.in: Use AC_FUNC_STRNLEN.
15309 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
15311 2002-01-09 Akim Demaille <akim@epita.fr>
15313 * src/files.c, src/files.h (output_infix): New.
15314 (tab_extension): Remove.
15315 (compute_base_names): Compute the former, drop the latter.
15316 * src/output.c (prepare): Insert the muscles `output-infix', and
15318 * src/parse-skel.y (string, string.1): New.
15319 (section.header): Use it.
15320 (section.yacc): Remove.
15321 (prefix): Remove too.
15322 * src/scan-skel.l: Adjust.
15323 * src/bison.simple, src/bison.hairy: Adjust.
15325 2002-01-09 Akim Demaille <akim@epita.fr>
15327 * configure.in (WERROR_CFLAGS): Compute it.
15328 * src/Makefile.am (CFLAGS): Pass it.
15329 * tests/atlocal.in (CFLAGS): Idem.
15330 * src/files.c: Fix a few warnings.
15331 (get_extension_index): Remove, unused.
15333 2002-01-08 Akim Demaille <akim@epita.fr>
15335 * src/getargs.c (AS_FILE_NAME): New.
15336 (getargs): Use it to convert DOSish file names.
15337 * src/files.c (base_name): Rename as full_base_name to avoid
15338 clashes with `base_name ()'.
15339 (filename_split): New.
15340 (compute_base_names): N-th rewrite, using filename_split.
15342 2002-01-08 Akim Demaille <akim@epita.fr>
15344 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
15345 New, stolen from the Fileutils 4.1.
15346 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
15347 * configure.in: Check for the presence of memrchr, and of its
15350 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
15352 * lib/hash.h (__P): Added definition for this macro.
15353 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
15354 BUILT_SOURCES, to ensure they are generated first.
15355 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
15356 %error-verbose to allow bootstrapping with bison 1.30x.
15358 2002-01-06 Akim Demaille <akim@epita.fr>
15360 * src/reader.c (parse_braces): Don't fetch the next char, the
15361 convention is to fetch on entry.
15362 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
15363 'switch' without a following semicolon.
15364 * tests/regression.at (braces parsing): New.
15366 2002-01-06 Akim Demaille <akim@epita.fr>
15368 Bison is dead wrong in its RR conflict reports.
15370 * tests/torture.at (GNU Cim Grammar): New.
15371 * src/conflicts.c (count_rr_conflicts): Fix.
15373 2002-01-06 Akim Demaille <akim@epita.fr>
15375 Creating package.m4 from configure.ac causes too many problems.
15377 * tests/Makefile.am (package.m4): Create it by hand,
15378 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
15380 2002-01-06 Akim Demaille <akim@epita.fr>
15382 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
15385 2002-01-04 Paul Eggert <eggert@twinsun.com>
15387 * doc/bison.texinfo (Debugging):
15388 Remove YYSTDERR; it's no longer defined or used.
15389 Also, s/cstdio.h/cstdio/.
15391 2002-01-03 Akim Demaille <akim@epita.fr>
15393 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
15395 2002-01-03 Akim Demaille <akim@epita.fr>
15397 * src/parse-skel.y (process_skeleton): Don't bind the parser's
15398 tracing code to --trace, wait for a better --trace option, with
15401 2002-01-03 Akim Demaille <akim@epita.fr>
15403 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
15404 The ISO C++ standard is extremely clear about it: stderr is
15405 considered a macro, not a regular symbol (see table 94 `Header
15406 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
15407 Therefore std:: does not apply to it. It still does with fprintf.
15408 Also, s/cstdio.h/cstdio/.
15410 2002-01-03 Akim Demaille <akim@epita.fr>
15412 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
15413 for non system headers.
15415 2002-01-02 Akim Demaille <akim@epita.fr>
15417 Equip the skeleton chain with location tracking, runtime trace,
15418 pure parser and scanner.
15420 * src/parse-skel.y: Request a pure parser, locations, and prefix
15422 (%union): Having several members with the same type does not help
15423 type mismatches, simplify.
15424 (YYPRINT, yyprint): New.
15425 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
15426 (skel_error): this.
15428 * src/scan-skel.l: Adjust to these changes.
15429 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
15430 (LOCATION_PRINT, skel_control_t): New.
15432 2001-12-30 Akim Demaille <akim@epita.fr>
15434 * src/parse-skel.y: Get rid of the shift/reduce conflict:
15435 replace `gb' with BLANKS.
15436 * src/scan-skel.l: Adjust.
15438 2001-12-30 Akim Demaille <akim@epita.fr>
15440 * src/system.h: We don't need nor want bcopy.
15441 Throw away MS-DOS crap: we don't need getpid.
15442 * configure.in: We don't need strndup. It was even causing
15443 problems: because Flex includes the headers *before* us,
15444 _GNU_SOURCE is not defined by config.h, and therefore strndup was
15446 * lib/xstrndup.c: New.
15447 * src/scan-skel.l: Use it.
15448 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
15449 * src/parse-skel.y: Use %directives instead of #defines.
15451 2001-12-30 Akim Demaille <akim@epita.fr>
15453 * src/skeleton.h: New.
15454 * src/output.c (output_parser, output_master_parser): Remove, dead
15456 * src/output.h (get_lines_number, actions_output, guards_output)
15457 (token_definitions_output): Prototype them.
15458 * src/parse-skel.y: Add the license notice.
15459 Include output.h and skeleton.h.
15460 (process_skeleton): Returns void, and takes a single parameter.
15461 * src/scan-skel.l: Add the license notice.
15462 Include skeleton.h.
15463 Don't use %option yylineno: it seems that then Flex imagines
15464 REJECT has been used, and therefore it won't reallocate its
15465 buffers (which makes no other sense to me than a bug). It results
15466 in warnings for `unused: yy_flex_realloc'.
15468 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
15470 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15471 (MUSCLE_INSERT_PREFIX): ...to there.
15472 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15473 (MUSCLE_INSERT_PREFIX): Move from here...
15475 * src/bison.hairy: Add a section directive. Put braces around muscle
15476 names. This parser skeleton is still broken, but Bison should not
15477 choke on a bad muscle 'syntax'.
15478 * src/bison.simple: Add a section directive. Put braces around muscle
15481 * src/files.h (strsuffix, stringappend): Add declarations.
15482 (tab_extension): Add declaration.
15483 (short_base_name): Add declaration.
15485 * src/files.c (strsuffix, stringappend): No longer static. These
15486 functions are used in the skeleton parser.
15487 (tab_extension): New.
15488 (compute_base_names): Use the computations done in this function
15489 to guess if the generated parsers should have '.tab' in their
15491 (short_base_name): No longer static.
15493 * src/output.c (output_skeleton): New.
15494 (output): Disable call to output_master_parser, and give a try to
15495 a new skeleton handling system.
15496 (guards_output, actions_output): No longer static.
15497 (token_definitions_output, get_lines_number): No longer static.
15499 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
15501 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
15504 * src/parse-skel.y: New file.
15505 * src/scan-skel.l: New file.
15507 2001-12-29 Akim Demaille <akim@epita.fr>
15509 %name-prefix is broken.
15511 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
15512 Adjust all dependencies.
15513 * tests/headers.at (export YYLTYPE): Strengthen this test: use
15516 Renaming yylval but not yylloc is not consistent. Now we do.
15518 * src/bison.simple: Prefix yylloc if used.
15519 * doc/bison.texinfo (Decl Summary): Document that.
15521 2001-12-29 Akim Demaille <akim@epita.fr>
15523 * doc/bison.texinfo: Promote `%long-directive' over
15525 Remove all references to fixed-output-files, yacc is enough.
15527 2001-12-29 Akim Demaille <akim@epita.fr>
15529 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
15530 user prologue. These are defaults.
15531 * tests/actions.at (Mid-rule actions): Make sure the user can
15532 define YYDEBUG and YYERROR_VERBOSE.
15534 2001-12-29 Akim Demaille <akim@epita.fr>
15536 * src/output.c (header_output): Don't forget to export YYLTYPE and
15538 * tests/headers.at (export YYLTYPE): New, make sure it does.
15539 * tests/regression.at (%union and --defines, Invalid CPP headers):
15541 * tests/headers.at: here.
15543 2001-12-29 Akim Demaille <akim@epita.fr>
15545 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
15547 2001-12-29 Akim Demaille <akim@epita.fr>
15549 * tests/actions.at (Mid-rule actions): Output on a single line
15550 instead of several.
15552 2001-12-29 Akim Demaille <akim@epita.fr>
15554 * doc/bison.texinfo: Formatting changes.
15556 2001-12-29 Akim Demaille <akim@epita.fr>
15558 Don't store the token defs in a muscle, just be ready to output it
15559 on command. Now possible via `symbols'. Fixes a memory leak.
15561 * src/output.c (token_definitions_output): New.
15562 (output_parser, header_output): Use it.
15563 * src/reader.c (symbols_save): Remove.
15565 2001-12-29 Akim Demaille <akim@epita.fr>
15567 * src/bison.simple: Do not provide a default for YYSTYPE and
15568 YYLTYPE before the user's prologue. Otherwise it's hardly... a
15571 2001-12-29 Akim Demaille <akim@epita.fr>
15573 Mid-rule actions are simply... ignored!
15575 * src/reader.c (readgram): Be sure to attach mid-rule actions to
15576 the empty-rule associated to the dummy symbol, not to the host
15578 * tests/actions.at (Mid-rule actions): New.
15580 2001-12-29 Akim Demaille <akim@epita.fr>
15584 * src/reader.c (reader): Free grammar.
15586 2001-12-29 Akim Demaille <akim@epita.fr>
15590 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
15591 since it allocates it for each state, although only one is needed.
15592 (allocate_storage): Do it here.
15594 2001-12-29 Akim Demaille <akim@epita.fr>
15596 * src/options.h, src/options.c (create_long_option_table): Rename
15598 (long_option_table_new): this, with a clearer prototype.
15599 (percent_table): Remove, unused,
15600 * src/getargs.c (getargs): Adjust.
15602 2001-12-29 Akim Demaille <akim@epita.fr>
15604 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
15605 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
15608 2001-12-29 Akim Demaille <akim@epita.fr>
15610 * src/lalr.c (build_relations): Rename `states' as `states1'.
15611 Sorry, I don't understand exactly what it is, no better name...
15613 2001-12-29 Akim Demaille <akim@epita.fr>
15615 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
15616 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
15617 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
15620 2001-12-29 Akim Demaille <akim@epita.fr>
15622 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
15625 2001-12-29 Akim Demaille <akim@epita.fr>
15627 * src/reader.c, src/reader.h (user_toknums): Remove.
15628 Adjust all users to use symbols[i]->user_token_number.
15630 2001-12-29 Akim Demaille <akim@epita.fr>
15632 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
15633 Adjust all users to use symbols[i]->prec or ->assoc.
15635 2001-12-29 Akim Demaille <akim@epita.fr>
15637 * src/reader.c, src/reader.h (tags): Remove.
15638 Adjust all users to use symbols[i]->tag.
15640 2001-12-29 Akim Demaille <akim@epita.fr>
15642 * src/gram.h, src/gram.c (symbols): New, similar to state_table
15644 * src/reader.c (packsymbols): Fill this table.
15646 * src/conflicts.c (resolve_sr_conflict): Adjust.
15647 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
15649 Use symbols[i]->tag instead of tags[i].
15651 2001-12-29 Akim Demaille <akim@epita.fr>
15653 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
15654 In addition, put a comment in there, to replace...
15655 * tests/regression.at (%union and C comments): Remove.
15657 2001-12-29 Akim Demaille <akim@epita.fr>
15659 * tests/regression.at (Web2c Actions): Blindly move the actual
15660 output as expected output. The contents *seem* right to me, but I
15661 can't pretend reading perfectly parser tables... Nonetheless, all
15662 the other tests pass correctly, the table look OK, even though the
15663 presence of `$axiom' is to be noted: AFAICS it is useless (but
15666 2001-12-29 Akim Demaille <akim@epita.fr>
15668 * src/reader.c (readgram): Don't add the rule 0 if there were no
15669 rules read. In other words, add it _after_ having performed
15670 grammar sanity checks.
15671 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
15673 2001-12-29 Akim Demaille <akim@epita.fr>
15675 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
15676 visible, and some states have now a different number.
15678 2001-12-29 Akim Demaille <akim@epita.fr>
15680 * src/reader.c (readgram): Bind the initial rule's lineno to that
15682 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
15683 (Solved SR Conflicts): Adjust rule 0's line number.
15685 2001-12-29 Akim Demaille <akim@epita.fr>
15687 Fix the `GAWK Grammar' failure.
15689 * src/LR0.c (final_state): Initialize to -1 so that we do compute
15690 the reductions of the first state which was mistakenly confused
15691 with the final state because precisely final_state was initialized
15693 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
15694 now noticed by Bison.
15695 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
15696 have a reduction on $default.
15698 2001-12-29 Akim Demaille <akim@epita.fr>
15700 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
15702 * src/closure.c (print_closure): Likewise.
15703 * src/derives.c (print_derives): Likewise.
15704 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
15707 2001-12-29 Akim Demaille <akim@epita.fr>
15709 * src/lalr.c (lookaheads_print): New.
15710 (lalr): Call it when --trace-flag.
15711 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
15714 2001-12-29 Akim Demaille <akim@epita.fr>
15716 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
15717 when walking through ritem, even via rule->rhs.
15718 * src/reduce.c (dump_grammar, useful_production, reduce_output)
15719 (useful_production, useless_nonterminals): Likewise.
15720 (reduce_grammar_tables): Likewise, plus update nritems.
15721 * src/nullable.c (set_nullable): Likewise.
15722 * src/lalr.c (build_relations): Likewise.
15723 * tests/sets.at (Nullable): Adjust.
15724 Fortunately, now, the $axiom is no longer nullable.
15726 2001-12-29 Akim Demaille <akim@epita.fr>
15728 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

15731 * src/reduce.c (nonterminals_reduce): Likewise.
15732 * src/print_graph.c (print_graph): Likewise.
15733 * src/output.c (output_rule_data): Likewise.
15734 * src/nullable.c (set_nullable): Likewise.
15736 2001-12-29 Akim Demaille <akim@epita.fr>
15738 * src/output.c: Comment changes.
15740 2001-12-27 Paul Eggert <eggert@twinsun.com>
15742 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
15743 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
15744 Sparc, as they were causing more porting problems than the
15745 (minor) performance improvement was worth.
15747 Also, catch up with 1.31's YYSTD.
15749 2001-12-27 Akim Demaille <akim@epita.fr>
15751 * src/output.c (output_gram): Rely on nritems, not the
15752 0-sentinel. See below.
15753 Use -1 as separator, not 0.
15754 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
15755 Rely on -1 as separator in yyrhs, instead of 0.
15756 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
15757 twice `Now at end of input', therefore there are two lines less to
15760 2001-12-27 Akim Demaille <akim@epita.fr>
15762 * tests/regression.at (Unresolved SR Conflicts):
15763 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
15766 2001-12-27 Akim Demaille <akim@epita.fr>
15768 * src/LR0.c (new_state): Recognize the final state by the fact it
15769 is reached by eoftoken.
15770 (insert_start_shifting_state, insert_eof_shifting_state)
15771 (insert_accepting_state, augment_automaton): Remove, since now
15772 these states are automatically computed from the initial state.
15773 (generate_states): Adjust.
15774 * src/print.c: When reporting a rule number to the user, substract
15775 1, so that the axiom rule is rule 0, and the first user rule is 1.
15776 * src/reduce.c: Likewise.
15777 * src/print_graph.c (print_core): For the time being, just as for
15778 the report, depend upon --trace-flags to dump the full set of
15780 * src/reader.c (readgram): Once the grammar read, insert the rule
15781 0: `$axiom: START-SYMBOL $'.
15782 * tests/set.at: Adjust: rule 0 is now displayed, and since the
15783 number of the states has changed (the final state is no longer
15784 necessarily the last), catch up.
15786 2001-12-27 Akim Demaille <akim@epita.fr>
15788 Try to make the use of the eoftoken valid. Given that its value
15789 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
15790 is used instead of > 0 where appropriate, (ii), depend upon nritems
15791 instead of the 0-sentinel.
15793 * src/gram.h, src/gram.c (nritems): New.
15794 Expected to be duplication of nitems, but for the time being...
15795 * src/reader.c (packgram): Assert nritems and nitems are equal.
15796 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
15797 * src/closure.c (print_closure, print_fderives): Likewise.

15799 * src/print.c (print_core, print_grammar): Likewise.
15800 * src/print_graph.c: Likewise.
15802 2001-12-27 Akim Demaille <akim@epita.fr>
15804 * src/main.c (main): If there are complains after grammar
15805 reductions, then output the report anyway if requested, then die.
15806 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
15807 * src/reader.c (eoftoken): New.
15808 (parse_token_decl): If the token being defined has value `0', it
15810 (packsymbols): No longer hack `tags' to insert `$' by hand.
15811 Be sure to preserve the value of the eoftoken.
15812 (reader): Make sure eoftoken is defined.
15813 Initialize nsyms to 0: now eoftoken is created just like the others.
15814 * src/print.c (print_grammar): Don't special case the eof token.
15815 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
15816 lie anyway, albeit pleasant.
15817 * tests/calc.at: Exercise error messages with eoftoken.
15818 Change the grammar so that empty input is invalid.
15819 Adjust expectations.
15820 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
15822 2001-12-27 Akim Demaille <akim@epita.fr>
15824 * configure.in: Check the protos of strchr ans strspn.
15825 Replace strchr if needed.
15826 * src/system.h: Provide the protos of strchr, strspn and memchr if
15828 * lib/strchr.c: New.
15829 * src/reader.c (symbols_save): Use strchr.
15831 2001-12-27 Akim Demaille <akim@epita.fr>
15833 * src/print.c, src/print_graph.c (escape): New.
15834 Use it to quote the TAGS outputs.
15835 * src/print_graph.c (print_state): Now errors are in red, and
15836 reductions in green.
15837 Prefer high to wide: output the state number on a line of its own.
15839 2001-12-27 Akim Demaille <akim@epita.fr>
15841 * src/state.h, src/state.c (reductions_new): New.
15842 * src/LR0.c (set_state_table): Let all the states have a
15843 `reductions', even if reduced to 0.

15862 2001-12-27 Akim Demaille <akim@epita.fr>
15864 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
15865 * src/print.c: here.
15866 (lookaheadset, shiftset): New, used as additional storage by
15868 (print_results): Adjust.
15869 (print_shifts, print_gotos, print_errs): New, extracted from...
15870 (print_actions): here.
15871 * src/print_graph.c (print_actions): Remove dead code.
15873 2001-12-27 Akim Demaille <akim@epita.fr>
15875 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
15878 2001-12-27 Akim Demaille <akim@epita.fr>
15880 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
15881 (build_relations): Adjust.

15895 * src/output.c (output): Adjust.
15896 * src/reader.c (parse_braces): New, factoring...
15897 (copy_action, copy_guard): these two which are renamed as...
15898 (parse_action, parse_guard): these.
15899 As a voluntary consequence, using braces around guards is now
15902 2001-12-27 Akim Demaille <akim@epita.fr>
15904 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
15905 * src/reader.c (symbol_list): `guard' and `guard_line' are new
15907 (symbol_list_new): Adjust.
15908 (copy_action): action_line is the first line, not the last.
15909 (copy_guard): Just as for actions, store the `action' only, not
15910 the switch/case/break flesh.
15911 Don't parse the user action that might follow the guard, let...
15912 (readgram): do it, i.e., now, there can be an action after a
15914 In other words the guard is just explicitly optional.
15915 (packgram): Adjust.
15916 * src/output.c (guards_output): New.
15917 (output_parser): Call it when needed.
15918 (output): Also free the guard and attrs obstacks.
15919 * src/files.c, src/files.h (obstack_save): Remove.
15920 (output_files): Remove.
15921 As a result, if one needs the former `.act' file, using an
15922 appropriate skeleton which requires actions and guards is now
15924 * src/main.c (main): Adjust.
15925 * tests/semantic.at: New.
15926 * tests/regression.at: Use `input.y' as input file name.
15927 Avoid 8+3 problems by requiring input.c when the test needs the

15932 * src/reader.c (symbol_list_new): Be sure to initialize all the
15935 2001-12-27 Akim Demaille <akim@epita.fr>
15937 All the hacks using a final pseudo state are now useless.
15939 * src/LR0.c (set_state_table): state_table holds exactly nstates.
15940 * src/lalr.c (nLA): New.
15941 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
15942 instead of lookaheadsp from the pseudo state (nstate + 1).
15944 2001-12-27 Akim Demaille <akim@epita.fr>
15946 * src/output.c (action_row, token_actions): Use a state_t instead
15947 of a integer, and nlookaheads instead of the following state's

15954 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
15955 (conflicts_print, print_reductions): Use a state_t instead of an
15956 integer when referring to a state.
15957 As much as possible, depend upon nlookaheads, instead of the
15958 `lookaheadsp' member of the following state (since lookaheads of
15959 successive states are successive, the difference between state n + 1
15960 and n served as the number of lookaheads for state n).
15961 * src/lalr.c (add_lookback_edge): Likewise.
15962 * src/print.c (print_core, print_actions, print_state)
15963 (print_results): Likewise.

15973 Add plenty of `static'.
15975 2001-12-27 Akim Demaille <akim@epita.fr>
15977 * src/output.c (prepare): Drop the muscle `ntbase' which
15978 duplicates ntokens.
15979 * src/bison.simple: Formatting/comment changes.
15980 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
15981 is an undocumented synonym.
15983 2001-12-22 Akim Demaille <akim@epita.fr>
15985 * src/output.c (output_table_data): Change the prototype to use
15986 `int' for array ranges: some invocations do pass an int, not a
15988 Reported by Wayne Green.
15990 2001-12-22 Akim Demaille <akim@epita.fr>
15992 Some actions of web2c.y are improperly triggered.
15993 Reported by Mike Castle.
15995 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

16008 2001-12-18 Akim Demaille <akim@epita.fr>
16010 Some host fail on `assert (!"foo")', which expands to
16011 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
16012 Reported by Nelson Beebee.
16014 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
16015 `#define it_succeeded 0' and `assert (it_succeeded)'.
16017 2001-12-17 Marc Autret <autret_m@epita.fr>
16019 * src/bison.simple: Don't hard code the skeleton line and filename.
16020 * src/output.c (output_parser): Rename 'line' as 'output_line'.
16021 New line counter 'skeleton_line' (skeleton-line muscle).
16023 2001-12-17 Paul Eggert <eggert@twinsun.com>
16025 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
16026 YYDEBUG must be defined to a nonzero value.
16028 * src/bison.simple (yytname): Do not assume that the user defines
16029 YYDEBUG to a properly parenthesized expression.
16031 2001-12-17 Akim Demaille <akim@epita.fr>
16033 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
16034 nlookaheads is a new member.
16036 * src/lalr.h (nlookaheads): Remove this orphan declaration.
16037 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
16040 2001-12-17 Akim Demaille <akim@epita.fr>
16042 * src/files.h, src/files.c (open_files, close_files): Remove.
16043 * src/main.c (main): Don't open/close files, nor invoke lex_free,
16045 * src/reader.c (reader): Do it.
16047 2001-12-17 Akim Demaille <akim@epita.fr>
16049 * src/conflicts.c (print_reductions): Formatting changes.
16051 2001-12-17 Akim Demaille <akim@epita.fr>

16062 * src/reader.h (muscle_obstack): Move to...
16063 * src/output.h: here, since it's defined in output.c.
16065 2001-12-17 Akim Demaille <akim@epita.fr>
16067 * src/output.c (action_row, save_column, default_goto)

16083 2001-12-16 Marc Autret <autret_m@epita.fr>
16085 * src/output.c (actions_output): Fix. When we use %no-lines,
16086 there is one less line per action.
16088 2001-12-16 Marc Autret <autret_m@epita.fr>
16090 * src/bison.simple: Remove a useless #line directive.
16091 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
16092 * src/output.c (get_lines_number): New.
16093 (output_parser): Adjust, now takes care about the lines of a
16095 Fix line numbering.
16096 (actions_output): Computes the number of lines taken by actions.
16097 (output_master_parser): Insert new skeleton which is the name of
16098 the output parser file name.
16100 2001-12-15 Marc Autret <autret_m@epita.fr>
16102 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
16104 2001-12-15 Marc Autret <autret_m@epita.fr>
16106 * src/output.c (output_gram): Keep track of the hairy one.
16108 2001-12-15 Akim Demaille <akim@epita.fr>
16110 Make `make distcheck' work.
16112 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
16113 system.h which uses libgettext.h.
16115 2001-12-15 Akim Demaille <akim@epita.fr>
16117 * src/nullable.c (set_nullable): Useless rules must be skipped,
16118 otherwise, since we range over their symbols, we might look at a
16119 nonterminal which no longer ``exists'', i.e., it is not counted in
16120 `nvars', hence we overflow our arrays.
16122 2001-12-15 Akim Demaille <akim@epita.fr>
16124 The header can also be produced directly, without any obstack!
16127 * src/files.c, src/files.h (defines_obstack): Remove.
16128 (compute_header_macro): Global.
16129 (defines_obstack_save): Remove.
16130 * src/reader.c (parse_union_decl): No longer output to
16131 defines_obstack: its content can be found in the `stype' muscle
16133 (output_token_translations): Merge into...
16134 (symbols_output): this.
16136 (symbols_save): this.
16138 * src/output.c (header_output): New.
16141 2001-12-15 Akim Demaille <akim@epita.fr>
16143 * src/reader.c (parse_union_decl): Instead of handling two obstack
16144 simultaneously, use one to define the `stype' muscle, and use the
16145 value of the latter to fill defines_obstack.
16146 (copy_comment): Remove.
16147 (copy_comment2): Work for a single obstack.
16149 (copy_comment): this.
16151 2001-12-15 Akim Demaille <akim@epita.fr>
16153 * src/lex.c, src/lex.h (xgetc): No longer static.
16154 * src/reader.c (parse_union_decl): Revamp.
16156 2001-12-15 Akim Demaille <akim@epita.fr>
16158 Still making progress in separating Bison into (i) input, (ii)
16159 process, (iii) output: now we can directly output the parser file
16160 without using table_obstack at all.
16162 * src/files.c, src/files.h (table_obstack): Bye bye.
16163 (parser_file_name): New.
16164 * src/files.c (compute_output_file_names): Compute it.
16165 * src/output.c (actions_output, output_parser)
16166 (output_master_parser): To a file instead of an obstack.
16168 2001-12-15 Akim Demaille <akim@epita.fr>
16170 Attach actions to rules, instead of pre-outputting them to
16173 * src/gram.h (rule_t): action and action_line are new members.
16174 * src/reader.c (symbol_list): Likewise.
16175 (copy_action): Save the actions within the rule.
16176 (packgram): Save them in rule_table.
16177 * src/output.c (actions_output): New.
16178 (output_parser): Use it on `%%actions'.
16179 (output_rule_data): Don't free rule_table.
16181 (prepare): Don't save the `action' muscle.
16182 * src/bison.simple: s/%%action/%%actions/.
16184 2001-12-15 Akim Demaille <akim@epita.fr>
16186 * src/reader.c (copy_action): When --yacc, don't append a `;'
16187 to the user action: let it fail if lacking.
16188 Suggested by Arnold Robbins and Tom Tromey.
16190 2001-12-14 Akim Demaille <akim@epita.fr>
16192 * src/lex.c (literalchar): Simply return the char you decoded, non
16193 longer mess around with obstacks and int pointers.
16194 Adjust all callers.
16196 2001-12-14 Akim Demaille <akim@epita.fr>
16198 * src/lex.c (literalchar): Don't escape the special characters,
16199 just decode them, and keep them as char (before, eol was output as
16200 the 2 char string `\n' etc.).
16201 * src/output.c (output_rule_data): Use quotearg to output the
16204 2001-12-13 Paul Eggert <eggert@twinsun.com>
16206 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
16207 Do not infringe on the global user namespace when using C++.
16208 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
16209 All uses of `fprintf' and `stderr' changed.
16211 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
16213 2001-12-13 Akim Demaille <akim@epita.fr>
16215 The computation of nullable is broken: it doesn't handle empty
16218 * tests/torture.at (GNU AWK Grammar): New.
16219 * tests/sets.at (Nullable): New.
16220 * src/nullable.c (set_nullable): Instead of blindly looping over
16221 `ritems', loop over the rules, and then over their rhs's.
16223 Work around Autotest bugs.
16225 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
16226 frame, because Autotest understand lines starting with a `+' as
16227 traces from the shell. Then, they are not processed properly.
16228 Admittedly an Autotest bug, but we don't have time to wait for
16229 Autotest to catch up.
16230 * tests/regression.at (Broken Closure): Adjust to the new table
16233 * tests/sets.at: here.
16235 2001-12-13 Akim Demaille <akim@epita.fr>
16237 * src/closure.c (closure): Use nrules instead of playing tricks
16238 with BITS_PER_WORD.
16240 2001-12-13 Akim Demaille <akim@epita.fr>
16242 * src/print.c (print_actions): Output the handling of `$' as the
16243 traces do: shifting the token EOF. Before EOF was treated as a
16245 * tests/regression.at: Adjust some tests.
16246 * src/print_graph.c (print_core): Complete the set of items via
16247 closure. The next-to-final and final states are still unsatisfying,
16248 but that's to be addressed elsewhere.
16249 No longer output the rule numbers, but do output the state number.
16250 A single loop for the shifts + gotos is enough, but picked a
16251 distinct color for each.
16252 (print_graph): Initialize and finalize closure.
16254 2001-12-13 Akim Demaille <akim@epita.fr>
16256 * src/reader.c (readgram): Remove dead code, an strip useless
16258 (get_type): Remove, unused.
16260 2001-12-12 Akim Demaille <akim@epita.fr>
16262 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
16263 on that of lib/error.c.
16265 2001-12-12 Akim Demaille <akim@epita.fr>
16267 Some hosts don't like `/' in includes.
16269 * src/system.h: Include libgettext.h without qualifying the path.
16270 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
16273 2001-12-11 Marc Autret <autret_m@epita.fr>
16275 * src/output.c (output_parser): Remove useless muscle.
16277 2001-12-11 Marc Autret <autret_m@epita.fr>
16279 * src/bison.simple: Remove #line just before %%epilogue. It
16280 is now handled in ...
16281 * src/reader.c (read_additionnal_code): Add the output of a
16282 #line for the epilogue.
16284 2001-12-10 Marc Autret <autret_m@epita.fr>
16286 * src/reader.c (copy_definition): Re-use CPP-outed code which
16287 replace precedent remove.
16288 * src/bison.simple: Remove #line before %%prologue because
16289 %%input-line is wrong at this time.
16291 2001-12-10 Marc Autret <autret_m@epita.fr>
16293 * src/reader.c (symbols_output): Clean up.
16294 * src/output.c (output_gram, output): Clean up.
16296 2001-12-10 Akim Demaille <akim@epita.fr>
16298 * src/lalr.c (initialize_lookaheads): New. Extracted from...
16299 * src/LR0.c (set_state_table): here.
16300 * src/lalr.c (lalr): Call it.
16302 2001-12-10 Akim Demaille <akim@epita.fr>
16304 * src/state.h (shifts): Remove the `number' member: shifts are
16305 attached to state, hence no longer need to be labelled with a
16308 2001-12-10 Akim Demaille <akim@epita.fr>
16310 Now that states have a complete set of members, the linked list of
16311 shifts is useless: just fill directly the state's shifts member.
16313 * src/state.h (shifts): Remove the `next' member.
16314 * src/LR0.c (first_state, last_state): Remove.
16315 Adjust the callers.
16316 (augment_automaton): Don't look for the shifts that must be added
16317 a shift on EOF: it is those of the state we looked for! But now,
16318 since shifts are attached, it is no longer needed to looking
16319 merely by its id: its number.
16321 2001-12-10 Akim Demaille <akim@epita.fr>
16323 * src/LR0.c (augment_automaton): Better variable locality.
16324 Remove an impossible branch: if there is a state corresponding to
16325 the start symbol being shifted, then there is shift for the start
16326 symbol from the initial state.
16328 2001-12-10 Akim Demaille <akim@epita.fr>
16330 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
16331 only when appropriate: when insert_start_shifting_state' is not
16333 * tests/regression.at (Rule Line Numbers): Adjust.
16335 2001-12-10 Akim Demaille <akim@epita.fr>
16337 * src/LR0.c (augment_automaton): Now that all states have shifts,
16338 merge the two cases addition shifts to the initial state.
16340 2001-12-10 Akim Demaille <akim@epita.fr>
16342 * src/lalr.c (set_state_table): Move to...
16344 * src/lalr.c (lalr): Don't call it...
16345 * src/LR0.c (generate_states): do it.
16346 * src/LR0.h (first_state): Remove, only the table is used.
16348 2001-12-10 Akim Demaille <akim@epita.fr>
16350 * src/LR0.h (first_shift, first_reduction): Remove.
16351 * src/lalr.c: Don't use first_shift: find shifts through the
16354 2001-12-10 Akim Demaille <akim@epita.fr>
16356 * src/LR0.c: Attach shifts to states as soon as they are
16358 * src/lalr.c (set_state_table): Instead of assigning shifts to
16359 state, just assert that the mapping was properly done.
16361 2001-12-10 Akim Demaille <akim@epita.fr>
16363 * src/LR0.c (insert_start_shift): Rename as...
16364 (insert_start_shifting_state): this.
16365 (insert_eof_shifting_state, insert_accepting_state): New.
16366 (augment_automaton): Adjust.
16367 Better locality of the variables.
16368 When looking if the start_symbol is shifted from the initial
16369 state, using `while (... symbol != start_symbol ...)' sounds
16370 better than `while (... symbol < start_symbol ...)': If fail
16371 to see how the order between symbols could be relevant!
16373 2001-12-10 Akim Demaille <akim@epita.fr>
16375 * src/getargs.h: Don't declare `spec_name_prefix' and
16376 `spec_file_prefix', declared by src/files.h.
16377 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
16378 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
16379 * src/output.c (prepare): Adjust.
16380 * src/reader.c (symbols_output): Likewise.
16381 * src/vmsgetargs.c: Vaguely adjust, but who cares?
16383 2001-12-10 Akim Demaille <akim@epita.fr>
16385 * src/muscle_tab.c (muscle_init): NULL is a better default than
16388 2001-12-10 Akim Demaille <akim@epita.fr>
16390 * src/reader.c (reader): Calling symbols_output once is enough.
16392 2001-12-10 Akim Demaille <akim@epita.fr>
16394 Now that states have a complete set of members, the linked list of
16395 reductions is useless: just fill directly the state's reductions
16398 * src/state.h (struct reductions): Remove member `number' and
16400 * src/LR0.c (first_reduction, last_reduction): Remove.
16401 (save_reductions): Don't link the new reductions, store them in
16403 * src/lalr.c (set_state_table): No need to attach reductions to
16404 states, it's already done.
16405 * src/output.c (output_actions): No longer free the shifts, then
16406 the reductions, then the states: free all the states and their
16409 2001-12-10 Akim Demaille <akim@epita.fr>
16411 * src/options.c (OPTN, DRTV, BOTH): New.
16412 (option_table): Use them.
16414 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
16415 the job of system.h.
16416 * src/options.c: Don't include stdio.h and xalloc.h for the same
16419 2001-12-10 Akim Demaille <akim@epita.fr>
16421 * src/output.c (output, prepare): Make sure the values of the
16422 muscles `action' and `prologue' are 0-terminated.
16424 2001-12-10 Akim Demaille <akim@epita.fr>
16426 Clean up GCC warnings.
16428 * src/reader.c (copy_action): `buf' is not used.
16429 (parse_skel_decl): Be static.
16430 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
16431 * src/options.h (create_long_option_table): Have a real prototype.
16432 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
16433 (hash_delete_at): Return const void *.
16434 Adjust casts to preserve the const.
16436 2001-12-10 Akim Demaille <akim@epita.fr>
16438 * configure.in: Require 2.52g.
16439 M4 is not needed, but AUTOM4TE is.
16440 * m4/m4.m4: Remove.
16441 * tests/Makefile.am: Adjust.
16443 2001-12-10 Akim Demaille <akim@epita.fr>
16445 One structure for states is enough, even though theoretically
16446 there are LR(0) states and LALR(1) states.
16448 * src/lalr.h (state_t): Remove.
16449 (state_table): Be state_t **, not state_t *.
16450 * src/state.h (core, CORE_ALLOC): Rename as...
16451 (state_t, STATE_ALLOC): this.
16452 Add the LALR(1) members: shifts, reductions, errs.
16453 * src/LR0.c (state_table): Rename as...
16454 (state_hash): this, to avoid name clashes with the global
16456 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
16457 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
16459 2001-12-10 Akim Demaille <akim@epita.fr>
16461 Bison dumps core on bash.y.
16462 Reported by Pascal Bart.
16464 * src/warshall.c (bitmatrix_print): New.
16466 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
16467 j must be the outer loop.
16468 * tests/regression.at (Broken Closure): New.
16470 2001-12-05 Akim Demaille <akim@epita.fr>
16472 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
16474 Reported by Peter Hamorsky.
16476 2001-12-05 Akim Demaille <akim@epita.fr>
16478 * src/conflicts.c (err_table): Remove.
16479 (resolve_sr_conflict): Adjust.
16480 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
16482 (state_t.reductions, state_t.shifts): this.
16484 2001-12-05 Akim Demaille <akim@epita.fr>
16486 * src/reduce.c (reduce_grammar_tables): No longer disable the
16487 removal of useless rules via CPP but via `if (0)', so that the
16488 compiler still check the code is valid.
16489 For instance, it should have noticed `rline' no longer exists: use
16490 the `line' member of rule_t.
16491 * src/gram.c (dummy, rline): Remove, unused.
16493 2001-12-05 Akim Demaille <akim@epita.fr>
16495 * src/output.c (pack_vector): Use assert, not berror.
16496 * src/main.c (berror): Remove, unused.
16498 2001-12-05 Akim Demaille <akim@epita.fr>
16500 New experimental feature: if --verbose --trace output all the
16501 items of a state, not only its kernel.
16503 * src/print.c (print_core): If `trace_flag', then invoke closure
16504 before outputting the items of the state (print_core is no longer
16505 a correct name them).
16506 (print_results): Invoke new_closure/free_closure if needed.
16508 2001-12-05 Akim Demaille <akim@epita.fr>
16510 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
16511 * src/closure.c, src/closure.h (itemsetsize): Rename as...
16512 (nitemset): for consistency with the rest of the project.
16514 2001-12-05 Akim Demaille <akim@epita.fr>
16516 * src/closure.c (print_closure): Improve.
16517 (closure): Use it for printing input and output.
16519 2001-12-05 Akim Demaille <akim@epita.fr>
16521 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
16522 indexed by nonterminals.
16524 2001-12-05 Akim Demaille <akim@epita.fr>
16526 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
16528 * src/warshall.h: Remove accidental duplication of the content.
16530 2001-12-05 Akim Demaille <akim@epita.fr>

16542 2001-12-05 Akim Demaille <akim@epita.fr>
16544 * src/output.c (action_row): De-obfuscate
16545 using the good o' techniques: arrays not pointers, variable
16546 locality, BITISSET, RESETBIT etc.
16548 2001-12-05 Akim Demaille <akim@epita.fr>
16550 Pessimize the code to simplify it: from now on, all the states
16551 have a valid SHIFTS, which NSHIFTS is possibly 0.
16553 * src/LR0.c (shifts_new): Be global and move to..
16554 * src/state.c, src/state.h: here.
16555 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
16556 * src/print_graph: Adjust.
16558 2001-12-05 Akim Demaille <akim@epita.fr>
16560 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
16561 * src/conflicts.c: Use it.
16562 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
16563 incorrectly ``simplified''.
16565 2001-12-05 Akim Demaille <akim@epita.fr>
16567 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
16568 using the good o' techniques: arrays not pointers, variable
16569 locality, BITISSET, RESETBIT etc.
16571 2001-12-05 Akim Demaille <akim@epita.fr>
16573 * src/state.h (SHIFT_SYMBOL): New.
16574 * src/conflicts.c: Use it to deobfuscate.
16576 2001-12-05 Akim Demaille <akim@epita.fr>
16578 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
16579 (print_reductions): De-obfuscate using the good o' techniques:
16580 arrays not pointers, variable locality, BITISSET.
16582 2001-12-05 Akim Demaille <akim@epita.fr>
16584 * src/conflicts.c (print_reductions): Arrays, not pointers.
16587 2001-12-05 Akim Demaille <akim@epita.fr>
16589 * src/conflicts.c (print_reductions): Pessimize, but clarify.
16591 2001-12-05 Akim Demaille <akim@epita.fr>
16593 * src/conflicts.c (print_reductions): Improve variable locality.
16595 2001-12-05 Akim Demaille <akim@epita.fr>
16597 * src/conflicts.c (print_reductions): Pessimize, but clarify.
16599 2001-12-05 Akim Demaille <akim@epita.fr>
16601 * src/conflicts.c (print_reductions): Improve variable locality.
16603 2001-12-05 Akim Demaille <akim@epita.fr>
16605 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

16619 2001-12-05 Akim Demaille <akim@epita.fr>
16621 * src/lalr.c (maxrhs): Move to...
16622 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
16623 * src/lalr.c (build_relations): Adjust.
16625 2001-12-05 Akim Demaille <akim@epita.fr>
16627 * src/lalr.c (transpose): Free the memory allocated to the
16628 argument, as it is replaced by the results by the unique caller.
16629 (build_relations): Merely invoke transpose: it handles the memory
16631 Improve variable locality.
16632 Avoid variables used as mere abbreviations.
16633 (compute_lookaheads): Use arrays instead of pointers.
16635 2001-12-05 Akim Demaille <akim@epita.fr>
16637 * src/lalr.c (initialize_F): Improve variable locality.
16638 Avoid variables used as mere abbreviations.

16651 2001-12-05 Akim Demaille <akim@epita.fr>
16653 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
16654 the handling of squeue.
16655 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16657 2001-12-05 Akim Demaille <akim@epita.fr>
16659 Because useless nonterminals are now kept alive (instead of being
16660 `destroyed'), we now sometimes examine them, and store information
16661 related to them. Hence we need to know their number, and adjust
16662 memory allocations.
16664 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
16666 * src/LR0.c (allocate_itemsets): The memory allocated to
16667 `symbol_count' was used for two different purpose: once to count
16668 the number of occurrences of each symbol, and later reassigned to
16669 `shift_symbol', containing the symbol that can be shifted from a
16671 Deobfuscate, i.e., allocate, use and free `symbol_count' here
16673 (new_itemsets): Allocate `shift_symbol' here.
16674 (allocate_itemsets): symbol_count includes useless nonterminals.
16675 Make room for them.
16676 (free_storage): Use `free', not `XFREE', for pointers that cannot
16679 2001-12-05 Akim Demaille <akim@epita.fr>

16685 2001-12-05 Akim Demaille <akim@epita.fr>
16687 * src/gram.c, src/gram.h (ritem_print): New.
16688 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
16689 (This useless function was defined only to work around VMS linkers
16690 that can't handle compilation units with variables only).
16691 * src/reduce.c (dump_grammar): Use it to trace the construction of
16694 2001-12-04 Paul Eggert <eggert@twinsun.com>
16696 * src/bison.simple (union yyalloc): Change member names
16697 to be the same as the stack names.
16698 (yyparse): yyptr is now union yyalloc *, not char *.
16699 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
16700 and may generate better code on some machines.
16701 (yystpcpy): Use prototype if __STDC__ is defined, not just
16702 if __cplusplus is defined.
16704 2001-11-30 Akim Demaille <akim@epita.fr>
16706 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
16707 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
16708 Gettext doesn't compile cleanly, and dies with -Werror.
16709 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
16710 Include WARNING_CFLAGS here.
16711 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
16712 before being defined.
16714 2001-11-27 Paul Eggert <eggert@twinsun.com>
16716 * lib/quotearg.h (quotearg_n, quotearg_n_style):
16717 First arg is int, not unsigned.
16718 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
16719 (SIZE_MAX, UINT_MAX): New macros.
16720 (quotearg_n_options): Abort if N is negative.
16721 Avoid overflow check on hosts where size_t is 64 bits and int
16722 is 32 bits, as overflow is impossible there.
16723 Fix off-by-one typo that caused unnecessary reallocation.
16725 2001-11-29 Paul Eggert <eggert@twinsun.com>
16727 Name space cleanup in generated parser.
16729 * doc/bison.texinfo (Bison Parser): Discuss system headers
16730 and their effect on the user name space.
16732 * src/bison.simple:
16733 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
16734 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
16735 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
16737 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
16738 on user names when possible.
16740 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
16741 Simplify test for whather <alloca.h> exists.
16743 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
16745 (<stdio.h>): Include if YYDEBUG.
16747 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
16748 ! defined (yyoverflow) && ! defined (yymemcpy).
16750 (yymemcpy, yyparse): Rename local variables as needed so that
16751 they all begin with 'yy'.
16753 (yystrlen, yystpcpy): New functions.
16755 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
16758 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
16759 instead of relying on string.h functions. Use YYSTACK_ALLOC
16760 and YYSTACK_FREE instead of malloc and free.
16762 2001-11-30 Akim Demaille <akim@epita.fr>
16764 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
16765 before their first uses.

16772 2001-11-30 Akim Demaille <akim@epita.fr>
16774 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
16775 if body instead of `;' to pacify GCC's warnings.
16777 2001-11-30 Akim Demaille <akim@epita.fr>
16779 Instead of mapping the LHS of unused rules to -1, keep the LHS
16780 valid, but flag the rules as invalid.
16782 * src/gram.h (rule_t): `useful' is a new member.
16783 * src/print.c (print_grammar): Adjust.
16784 * src/derives.c (set_derives): Likewise.
16785 * src/reader.c (packgram, reduce_output): Likewise.
16786 * src/reduce.c (reduce_grammar_tables): Likewise.

16800 (reduce_output): Adjust.
16801 * tests/reduce.at (Useless Nonterminals): Adjust.
16803 2001-11-30 Akim Demaille <akim@epita.fr>

16813 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
16814 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
16816 (union yyalloc): New type.
16817 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
16818 an arbitrary restriction on hosts where size_t is wider than int.
16820 (yyparse): Don't dump core if alloca or malloc fails; instead, report
16821 a parser stack overflow. Allocate just one block of memory for all
16822 three stacks, instead of allocating three blocks; this typically is
16823 faster and reduces fragmentation.
16825 Do not limit the number of items in the stack to a value that fits
16826 in 'int', as this is an arbitrary limit on hosts with 64-bit
16827 size_t and 32-bit int.
16829 2001-11-29 Marc Autret <autret_m@epita.fr>
16831 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
16832 of defining YYERROR_VERBOSE.
16833 [AT_DATA]: $4 is now out of C declarations in the prologue.
16835 2001-11-28 Marc Autret <autret_m@epita.fr>

16879 * src/closure.c (closure): `b' and `ruleno' denote the same value:
16882 2001-11-28 Akim Demaille <akim@epita.fr>
16884 * src/closure.c (closure): Instead of looping over word in array
16885 then bits in words, loop over bits in array.
16887 2001-11-28 Akim Demaille <akim@epita.fr>
16889 * src/closure.c (closure): No longer optimize the special case
16890 where all the bits of `ruleset[r]' are set to 0, to make the code

16905 * src/reduce.c (dump_grammar): Don't translate trace messages.
16907 2001-11-28 Akim Demaille <akim@epita.fr>
16909 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
16910 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

17002 conflicts as expected.
17003 * tests/regression.at (%expect right): Adjust.
17005 2001-11-23 Akim Demaille <akim@epita.fr>

17026 2001-11-23 Akim Demaille <akim@epita.fr>

18672 * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
18673 * src/lex.c (maxtoken, grow_token_buffer): Static.
18675 2001-01-18 Akim Demaille <akim@epita.fr>
18677 Since we now use obstacks, more % directives can be enabled.
18679 * src/lex.c (percent_table): Also accept `%yacc',
18680 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
18682 Handle the actions for `%semantic_parser' and `%pure_parser' here,

18685 * src/reader.c (read_declarations): Adjust.
18686 * src/files.c (open_files): Don't call `compute_base_names', don't

18690 * src/output.c (output_headers): Document the fact that this patch
18691 introduces a guaranteed SEGV for semantic parsers.

18702 * src/conflicts.c: Return a string.
18703 * src/system.h (obstack_grow_string): Rename as...
18704 (obstack_sgrow): this. Be ready to work with non literals.
18705 (obstack_fgrow4): New.
18707 2000-12-20 Akim Demaille <akim@epita.fr>
18709 * src/files.c (open_files): Fix the computation of short_base_name

18760 (obstack_grow_string): this.
18761 * src/output.c (output_parser): Recognize `%% actions' instead of

18768 * src/output.c (output_parser): Compute the `#line' lines when

18793 2000-12-19 Akim Demaille <akim@epita.fr>
18795 * src/files.c (open_files): Yipee! We no longer need all the code
18796 looking for `/tmp' since we have no tmp file.
18798 2000-12-19 Akim Demaille <akim@epita.fr>
18800 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

18807 Provide a default definition.

18825 2000-11-17 Akim Demaille <akim@epita.fr>
18827 * lib/obstack.h: Formatting changes.
18828 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
18829 prevents type checking.
18830 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
18831 cast the value to (void *): assigning a `foo *' to a `void *'

18853 Use them to declare the variables which are global or local to
18856 2000-11-17 Akim Demaille <akim@epita.fr>
18858 * acconfig.h: Remove, no longer used.
18860 2000-11-07 Akim Demaille <akim@epita.fr>
18862 * src: s/Copyright (C)/Copyright/g.
18864 2000-11-07 Akim Demaille <akim@epita.fr>
18866 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
18868 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
18870 2000-11-07 Akim Demaille <akim@epita.fr>
18872 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

18878 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
18879 argument `data' for consistency with the prototypes.
18880 Qualify it `const'.
18881 (obstack_copy, obstack_copy0): Rename the second argument as
18882 `address' for consistency. Qualify it `const'.
18883 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
18884 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
18885 `const' their input argument (`data' or `address').
18886 Adjust the corresponding macros to include `const' in casts.
18888 2000-11-03 Akim Demaille <akim@epita.fr>
18890 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
18891 s/PFILE1/BISON_HAIRY/.
18892 Adjust dependencies.
18894 2000-11-03 Akim Demaille <akim@epita.fr>
18896 For some reason, this was not applied.
18898 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
18899 `unlink': it's no longer used.
18901 2000-11-03 Akim Demaille <akim@epita.fr>
18903 * src/files.c (skeleton_find): New function, eved out of...

18906 2000-11-03 Akim Demaille <akim@epita.fr>
18908 Don't use `atexit'.
18910 * src/files.c (obstack_save): New function.
18911 (done): Rename as...
18912 (output_files): this.
18913 Use `obstack_save'.
18914 * src/main.c (main): Don't use `atexit' to register `done', since
18915 it no longer has to remove tmp files, just call `output_files'
18916 when there are no errors.
18918 2000-11-02 Akim Demaille <akim@epita.fr>
18920 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
18921 `unlink': it's no longer used.
18922 * src/files.h: Formatting changes.
18924 2000-11-02 Akim Demaille <akim@epita.fr>
18926 Remove the last uses of mktemp and unlink/delete.
18928 * src/files.c (fdefines, ftable): Removed.
18929 (defines_ostack, table_obstack): New.
18930 Adjust dependencies of the former into uses of the latter.
18931 * src/output.c (output_short_or_char_table, output_short_table):

18944 * src/files.c (fattrs): Remove.
18945 (attrs_obstack): New.

18949 2000-11-01 Akim Demaille <akim@epita.fr>
18951 Introduce obstacks.
18952 Change each use of `faction' into a use of `action_obstack'.
18954 * lib/obstack.h, lib/obstack.c: New files.
18955 * src/files.c (faction): Remove.
18956 (action_obstack): New.
18957 Adjust all dependencies.
18959 2000-10-20 Akim Demaille <akim@epita.fr>
18961 * lib/quote.h (PARAMS): New macro. Use it.
18963 2000-10-16 Akim Demaille <akim@epita.fr>
18965 * src/output.c (output_short_or_char_table): New function.
18966 (output_short_table, output_token_translations): Use it.
18967 (goto_actions): Use output_short_table.
18969 2000-10-16 Akim Demaille <akim@epita.fr>

18974 * src/output.c (output_short_table): New argument to display the
18975 comment associated with the table.
18976 Adjust dependencies.
18977 (output_gram): Use it.
18978 (output_rule_data): Nicer output layout for YYTNAME.
18980 2000-10-16 Akim Demaille <akim@epita.fr>
18982 * src/lex.c (read_typename): New function.
18984 * src/reader.c (copy_dollar): Likewise.
18986 2000-10-16 Akim Demaille <akim@epita.fr>
18988 * src/reader.c (copy_comment2): Expect the input stream to be on
18989 the `/' which is suspected to open a comment, instead of being
18990 called after `//' or `/*' was read.
18991 (copy_comment, copy_definition, parse_union_decl, copy_action)
18992 (copy_guard): Adjust.
18994 2000-10-16 Akim Demaille <akim@epita.fr>
18996 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
18997 `read_signed_integer'.
18999 2000-10-16 Akim Demaille <akim@epita.fr>
19001 * src/reader.c (copy_dollar): New function.
19002 (copy_guard, copy_action): Use it.
19004 2000-10-16 Akim Demaille <akim@epita.fr>
19006 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
19007 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
19008 New files, from Fileutils 4.0.27.
19009 * src/main.c (printable_version): Remove.
19010 * src/lex.c, src/reader.c: Use `quote'.
19012 2000-10-04 Akim Demaille <akim@epita.fr>
19014 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
19016 2000-10-04 Akim Demaille <akim@epita.fr>
19018 * doc/bison.texinfo: Various typos spotted by Neil Booth.
19020 2000-10-04 Akim Demaille <akim@epita.fr>
19022 When a literal string is used to define two different tokens,
19023 `bison -v' segfaults.
19024 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
19026 * tests/regression.m4: New file.
19027 Include the core of the sample provided by Piotr Gackiewicz.
19028 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
19031 2000-10-04 Akim Demaille <akim@epita.fr>
19033 * src/reader.c (parse_expect_decl): Keep `count' within the size
19037 2000-10-02 Paul Eggert <eggert@twinsun.com>
19039 * bison.s1 (yyparse): Assign the default value
19040 unconditionally, to avoid a GCC warning and make the parser a
19043 2000-10-02 Akim Demaille <akim@epita.fr>
19045 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
19048 2000-10-02 Akim Demaille <akim@epita.fr>
19050 * src/derives.c, src/print.c, src/reduce.c: To ease the
19051 translation, move some `\n' out of the translated strings.
19053 2000-10-02 Akim Demaille <akim@epita.fr>
19055 The location tracking mechanism is precious for parse error
19056 messages. Nevertheless, it is enabled only when `@n' is used in
19057 the grammar, which is a different issue (you can use it in error
19058 message, but not in the grammar per se). Therefore, there should
19059 be another means to enable it.
19061 * src/getargs.c (getargs): Support `--locations'.
19062 (usage): Report it.
19063 * src/getargs.h (locationsflag): Export it.
19064 * src/lex.c (percent_table): Support `%locations'.
19065 * src/reader.c (yylsp_needed): Remove this variable, now replaced
19066 with `locationsflag'.
19067 * doc/bison.texinfo: Document `--locations' and `%locations'.
19069 * tests/calc.m4: Test it.
19071 For regularity of the names, replace each
19072 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
19073 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
19074 In addition replace each `flag' with `_flag'.
19076 2000-10-02 Akim Demaille <akim@epita.fr>
19078 Also test parse error messages, including with YYERROR_VERBOSE.
19080 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
19082 Use it to check the computations.
19083 Use it to check `nonassoc' is honored.
19084 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
19085 `--yyerror-verbose'.
19086 (_AT_CHECK_CALC): Adjust to this option.
19087 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
19089 2000-10-02 Akim Demaille <akim@epita.fr>
19091 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19092 the latter demonstrates a flaw in the handling of non debugging
19093 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19094 was used in order to simplify:
19110 unfortunately this leads to a CPP conflict when
19111 `--name-prefix=foo' is used since it produces `#define yydebug
19114 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
19115 (YYDPRINTF): New macro.
19117 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
19119 Also test `--verbose', `--defines' and `--name-prefix'.
19121 2000-10-02 Akim Demaille <akim@epita.fr>
19123 Improve the readability of the produced parsers.
19125 * src/bison.s1: Formatting changes.
19126 Improve the comment related to the `$' mark.
19127 (yydefault): Don't fall through to `yyresume': `goto' there.
19128 * src/output.c (output_parser): When the `$' is met, skip the end
19130 New variable, `number_of_dollar_signs', to check there's exactly
19131 one `$' in the parser skeleton.
19133 2000-10-02 Akim Demaille <akim@epita.fr>
19135 * lib/xstrdup.c: New file, from the fileutils.
19136 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
19137 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
19138 instead of strlen + xmalloc + strcpy.
19139 * src/symtab.c (copys): Remove, use xstrdup instead.
19141 2000-10-02 Akim Demaille <akim@epita.fr>
19143 * src/gram.h (associativity): New enum type which replaces the
19144 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
19145 `right_assoc', `left_assoc' and `non_assoc'.
19146 Adjust all dependencies.
19147 * src/reader.c: Formatting changes.
19148 (LTYPESTR): Don't define it, use it as a literal in
19149 `reader_output_yylsp'.
19150 * src/symtab.h (symbol_class): New enum type which replaces the
19151 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
19152 `sunknown', `stoken and `snterm'.
19154 2000-10-02 Akim Demaille <akim@epita.fr>
19156 * src/getargs.c (fixed_outfiles): Rename as...
19157 (yaccflag): for consistency and accuracy.
19158 Adjust dependencies.
19160 2000-10-02 Akim Demaille <akim@epita.fr>
19162 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19163 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19164 difficult and introduced a lot of core dump. It turns out that
19165 Bison used an implementation of `xmalloc' based on `calloc', and
19166 at various places it does depend upon the initialization to 0. I
19167 have not tried to isolate the pertinent places, and all the former
19168 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
19169 someone should address this issue.
19171 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
19172 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
19174 Adjust dependencies.
19175 * src/warshall.h: New file.
19178 2000-10-02 Akim Demaille <akim@epita.fr>
19180 Various anti-`extern in *.c' changes.
19182 * src/system.h: Include `assert.h'.
19184 2000-10-02 Akim Demaille <akim@epita.fr>
19186 * src/state.h (nstates, final_state, first_state, first_shift)
19187 (first_reduction): Move their exportation from here...
19188 * src/LR0.h: to here.
19189 Adjust dependencies.
19190 * src/getargs.c (statisticsflag): New variable.
19191 Add support for `--statistics'.
19192 Adjust dependencies.
