512 inside a new table in the general %define entry. Document `%define
513 namespace' there as well. Point the %name-prefix entry to it since it
514 explains it more completely in the case of C++.
515 (C++ Bison Interface): Mention `%define namespace' instead of
517 (Table of Symbols): Remove the `%define push_pull' entry. The %define
519 * tests/c++.at (Relative namespace references): New test case.

532 than 0 for the sake of synchronizing #line's, and define
533 b4_percent_define_syncline(VARIABLE).
534 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
535 * src/muscle_tab.c (muscle_syncline_grow): New.

547 muscle_percent_define_get_loc.
548 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.

558 * data/bison.m4 (b4_cat): New.
559 (b4_error, b4_error_at): Use b4_cat to send error directives directly
560 to stdout so they don't become arguments to other macros. Update
561 comments and add examples.
562 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
564 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
565 after printing the error directive so that M4 doesn't report subsequent
566 problems that are induced by this problem.
567 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
568 instead of just in them. Recognize @\n in both places. Both expand to
569 the empty string. Needed by b4_cat.
570 * tests/skeletons.at (Complaining during macro argument expansion):
572 (Fatal errors make M4 exit immediately): New test case.

595 2007-09-25 Joel E. Denny <jdenny@ces.clemson.edu>
597 Replace `%push-parser' and `%push-pull-parser' with

613 parsing requests here...
614 * data/yacc.c: ... hack this to switch to push.c any time
615 b4_use_push_pull_flag or the %define variable push_pull is set. This
616 will go away when we mv push.c yacc.c.
617 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
618 push parsing is not supported since unused %define variables are
620 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
621 * src/muscle_tab.h (muscle_percent_define_check_values): Update
622 comments for consistency with b4_percent_define_check_values.
623 * src/output.c (prepare): Don't insert b4_pull_flag and b4_push_flag

653 Problem reported by Wojciech Polak.
654 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.

744 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
746 In impure push mode, don't allow more than one yypstate to be allocated
747 since multiple impure parsers would corrupt yynerrs.
748 * data/push.c (yypstate_allocated): New static global variable

844 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
846 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
847 name user variables starting with `yy'. Just pass NULL instead of a
848 dummy local &yylval to yypush_parse.
849 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
852 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
854 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
855 true since it's then always used regardless of whether yyoverflow is
856 defined. Reported by Christian Burger at
857 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
858 * THANKS: Add Christian Burger.
860 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
861 node names: say "Decl Summary" not "Bison Declaration Summary".
863 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
865 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
866 determine whether this function has already complained about an invalid
867 value for a %define boolean variable, don't check whether Bison has
868 ever examined the value. As written, the check was a tautology.
869 Instead, record and check for this complaint using a separate muscle.
871 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
873 Fix push parsing memory leak reported by Brandon Lucia at
874 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
875 * THANKS: Add Brandon Lucia.
876 * data/push.c (yypstate_delete): Free the stack if it was reallocated
877 but the parse never completed and thus freed it.
878 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
879 * tests/testsuite.at: Include push.at.
881 (Push Parsing: Memory Leak for Early Deletion): New test case.

885 Improve handling of multiple S/R conflicts in the same state and of S/R
886 conflicts involving multiple reductions.
887 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
888 set for a state here or Bison will abort if it is reassigned on a
889 later conflicted reduction in the same state.
890 Similarly, don't finalize and assign the solved conflicts report here
891 or it will be lost if it is reassigned on a later conflicted reduction
893 (set_conflicts): Instead, assign them both here after all S/R conflicts
894 in the state have been fully examined.
895 * src/print.c (shift_set): Rename to...
896 (no_reduce_set): ... this.
897 (print_reductions): Update for rename, and add %nonassoc error action
898 tokens to no_reduce_set so that, when printing the first remaining
899 reduction on an error action token, the reduction is enclosed in
901 (print_results): Update for rename.
902 * tests/conflicts.at (Solved conflicts report for multiple reductions
903 in a state): New test case.
904 (%nonassoc error actions for multiple reductions in a state): New test
907 * src/main.c (main): Don't depend on C99 features.
909 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
911 * build-aux/.cvsignore: Add compile.
912 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
915 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
917 * bootstrap (slurp): Create target directories that don't exist.
918 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
920 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
922 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
924 * closure.c (closure): Likewise.
925 * state.h (reductions): Comment sorting of rules.
926 (state): Comment sorting of items.
928 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
930 Fix C++ test cases after recent Gnulib changes. Discussed starting at
931 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
932 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
933 definition in order to avoid Gnulib headers since we don't use config.h
935 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
936 rather than AT_DATA so that config.h is included.
938 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
940 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
941 instead of fprintf. Guard these functions with #if YYDEBUG instead of
942 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
943 and so that YYFPRINTF is guaranteed to be defined here.
945 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
947 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
949 (muscle_percent_define_check_values): ... this more helpful function.
950 Again, it's not used yet, but it will be.
951 * src/muscle_tab.h: Likewise.
953 Improve some comments in parser table construction.
954 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
955 (generate_states): Don't mention ruleset, which is internal to closure.
956 * src/closure.c (closure): Explain sorting of core and itemset, which
957 is required for this function to behave correctly.
958 * src/closure.h (closure): Mention sorting.
960 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
962 * src/lalr.c (state_lookahead_tokens_count): For code readability,
963 move the check for disabled transitions to an aver since conflict
964 resolution hasn't happened yet.
966 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
967 labels a state as inconsistent just because it has error transitions.
968 The original form of this check appeared in revision 1.1 of lalr.c,
969 which was committed on 1991-12-21. Now (at least), changing the
970 consistency label on such a state appears to have no useful effect in
971 any of the places it is examined, which I enumerate below. The key
972 point to understanding each item in this enumeration is that a state
973 with an error transition is labelled consistent in the first place only
974 if it has no rules, so the check cannot matter for states that have
975 rules. (1) Labelling a state as inconsistent will cause set_conflicts
976 to try to identify its conflicts, and a state must have *rules* to have
977 conflicts. (2) Labelling a state as inconsistent will affect how
978 action_row sets the default *rule* for the state. (3) Labelling a
979 state as inconsistent will cause build_relations to add lookback edges
980 to *rules* in that state.
981 * src/state.h (struct state): Word the comment for member consistent
984 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
986 Don't depend on C99 features.
987 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
988 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
989 * src/reader.c (check_and_convert_grammar): Fix for-loop.
990 * src/state.c (state_mark_reachable_states): Fix for-loop.
991 (state_remove_unreachable_states): Fix for-loop.
993 Don't widen struct state with member reachable just to temporarily
994 record reachability. Instead, use a local bitset.
995 * src/state.h (struct state): Remove member.
996 * src/state.c (state_new): Don't initialize it.
997 (state_mark_reachable_states): Rename to...
998 (state_record_reachable_states): ... this, and use bitset.
999 (state_remove_unreachable_states): Use bitset.
1001 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
1003 * src/Makefile.am (yacc): Quote target action commands properly so
1004 that the yacc script isn't corrupt. Reported by Hans Aberg at
1005 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
1007 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
1008 the case of pure parsers. Reported by Frans Englich at
1009 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
1010 * THANKS: Add Frans Englich.
1012 * NEWS (2.3a+): In the %code entry, reference section `Bison
1013 Declaration Summary' from the manual now since the %code summary has
1015 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
1016 in the rules section must be terminated by semicolons.
1018 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
1020 Extend the front-end API for %define variables to more completely
1021 mirror the back-end. This will be useful in the future.

1045 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
1046 tests/existing.at: Update copyright date.
1048 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1050 If conflict resolution makes states unreachable, remove those states,
1051 report rules that are then unused, and don't report conflicts in those
1053 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
1054 New global function.

1068 an unused rule is discovered.
1070 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1072 Minor code cleanup in parser table construction.
1073 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
1074 (new_itemsets, save_reductions): Update for rename to nitemset.
1075 * src/closure.c (nritemset): Rename to...
1076 (nitemset): ... this since the "r" appears to meaningless and isn't
1077 used in the comments.
1078 (closure): Update for rename.

1167 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
1168 Bison uses of names rather than just skeleton uses of names.
1169 (b4_percent_define_get, b4_percent_define_ifdef): Rename

1213 * data/lalr1.java: Prefix all private members with yy.
1215 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
1217 Use YYFPRINTF instead of fprintf where appropriate. Reported by

1235 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
1237 Undo my 2007-02-07 change, switching back to the c-strcase module
1238 introduced in the 2007-02-03 change. Bruno Haible reported that
1239 the 2007-02-07 change would be dangerous in Turkish if we add a
1240 language whose name contains "i", since "i" is not lowercase "I"
1242 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
1243 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
1244 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
1245 * m4/.cvsignore: Remove strcase.m4.
1246 * src/getargs.c: Revert 2007-02-07 change, as follows.

1248 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
1250 2007-02-11 Bruno Haible <bruno@clisp.org>
1252 Enable the Java related testsuite tests when the only Java compiler
1253 found is a gcj < 4.3. Discussed at
1254 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
1255 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
1257 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
1259 * data/Makefile.am: Update copyright date.
1260 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
1261 yypstate_new returns NULL.
1262 (yypstate_new): Return NULL if malloc does.
1263 * src/reader.c (packgram): Move translation of rule actions from the
1264 beginning of packgram to...
1265 (check_and_convert_grammar): ... here right before packgram is invoked
1266 so it's easier to write more complete comments, and remove redundant
1269 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
1271 As in semantic actions, make @$ in %initial-action, %destructor, and
1272 %printer imply %locations.
1273 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
1275 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
1276 (@$ in %initial-action implies %locations,
1277 @$ in %destructor implies %locations,
1278 @$ in %printer implies %locations): ... these new test cases.
1280 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
1282 Undo most of the 2007-02-03 change, switching to the strcase module
1283 now that gnulib strcase has been fixed.
1284 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
1285 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
1286 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
1287 * m4/.cvsignore: Add strcase.m4.
1288 * src/getargs.c: Revert 2007-02-03 change, as follows.
1289 Don't include c-strcase.h.
1290 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
1291 strcasecmp has "unspecified behavior" outside the POSIX locale,
1292 but it works fine in practice if at least one argument is ASCII,
1293 as is the case in Bison.
1295 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
1297 * tests/java.at: Skip tests if only one of javac/java is present.
1298 Reported by Joel E. Denny.
1299 * tests/atlocal.in: Adjust copyright years.
1301 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
1303 * data/lalr1.java (Stack): Work around old verifiers that disallow
1304 access to the private fields of an inner class, from the outer class.
1305 We can make Stack's fields public because user code doesn't have access
1306 to the instance of Stack used by parse(). Reported by Paul Eggert.
1308 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1310 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
1311 the right spot for these files?
1312 * bootstrap.conf (gnulib_modules): Add c-strcase.
1313 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
1315 * src/getargs.c: Include c-strcase.h.
1316 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
1317 to avoid unspecified behavior.
1319 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
1321 * doc/bison.texinfo (Decl Summary): Correct typo.
1323 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
1325 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.

1327 * data/c++.m4: Adjust default definitions of %define variables.
1328 * data/java.m4: Adjust default definitions of %define variables.
1329 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according

1343 * data/lalr1.java: New.
1345 * doc/bison.texinfo: Put "A Complete C++ Example" under
1346 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
1347 under Other Languages.
1349 * src/getargs.c (valid_languages): Add Java.
1350 * src/getargs.h (struct bison_language): Update size of string fields.
1352 * tests/Makefile.am: Add java.at.
1353 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
1354 * tests/java.at: New.
1355 * tests/testsuite.at: Include it.
1357 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
1360 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
1361 at_directive_argv arguments so these no longer have to be global
1362 variables. Also, update the implementation for the following changes.
1363 (fail_for_at_directive_too_many_args,
1364 fail_for_at_directive_too_few_args): Add at_directive_name argument.
1365 (at_directive_name): Remove as at_directive_argv[0] will be used for
1367 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
1368 for the directive name.

1372 (SC_AT_DIRECTIVE_ARG): Rename to...
1373 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
1374 (SC_AT_DIRECTIVE_SKIP_WS): Update.
1375 (scan_skel): Move yylex_destroy to...
1376 (skel_scanner_free): ... here.
1377 * tests/skeletons.at (installed skeleton file name): Rename to...
1378 (installed skeleton file names): ... this.
1380 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
1382 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1383 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
1384 Summary" not "Directives".
1385 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
1386 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
1387 since the former is now the more complete one.
1388 (Prologue Alternatives): Likewise and do the same for %defines.
1389 (Table of Symbols): Add summary of %code, add summary of %define, and
1390 move full %code documentation to...
1391 (Decl Summary): ... here for consistency with other entries in these
1393 Move %define entry in order to keep this list alphabetized.
1394 Reword %define entry a little to put less emphasis on the skeleton
1395 concept, which most users shouldn't have to think about.
1397 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
1399 Adjust to recent gnulib changes.
1400 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
1401 Add string.h, string_.h, unistd_.h, wchar_.h.
1402 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
1403 * src/system.h: Don't include <stpcpy.h>; this is now done by
1406 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
1408 Simplify implementation of unqualified %code, implement macros for
1409 uniform treatment of boolean %define flags. Document %define.
1410 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
1411 b4_percent_code_ifdef): New.
1412 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
1413 * data/c++.m4: Define default value for global_tokens_and_yystype.
1414 * data/glr.cc: Likewise.
1415 * data/location.cc: Use b4_percent_define_flag_if.
1417 * doc/bison.texinfo (Decl Summary): Document %define.
1419 * src/parse-gram.y (Unqualified %code): Change muscle name to
1421 (content.opt): Default to empty.
1423 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1425 Implement support for relative and absolute skeleton file names.
1426 Discussed starting at
1427 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
1428 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
1429 (Bison Options): Document in --skeleton entry.
1430 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
1431 full_skeleton can't necessarily hold all of pkgdatadir.
1432 If the specified skeleton file name contains a `/', don't prepend
1434 * src/parse-gram.y (prologue_declaration): If the specified skeleton
1435 file name contains a `/', prepend the grammar file directory.
1436 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
1437 * skeletons.at: New file.
1438 (relative skeleton file names): New test case.
1439 (installed skeleton file names): New test case.
1440 * tests/testsuite.at: Include skeletons.at.
1442 * bootstrap: Update copyright to 2007.
1444 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
1446 * bootstrap: Remove occurrences of .#bootmp from the files.
1448 2007-01-17 Akim Demaille <akim@epita.fr>
1450 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
1452 Use per-type %printer.
1454 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1456 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

1464 2007-01-16 Akim Demaille <akim@epita.fr>
1466 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
1468 (Calc++ Scanner): Exit with failure if we can't open the input
1470 Accept "-" standing for stdin.
1471 (Calc++ Top Level): Print the result only if the parsing was

1476 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
1478 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
1479 and Joel E. Denny <jdenny@ces.clemson.edu>
1481 Clean up %define and %code implementation in M4 some. Most
1482 importantly, rename all related macros to be in the b4_percent_define
1483 and b4_percent_code namespaces. Also, complete support for `.' in
1484 %define variable names and %code qualifiers.
1485 * data/bison.m4 (b4_check_user_names): Check for special
1486 "SKELETON-NAMESPACE(name)" macros instead of using two nested
1488 (b4_get_percent_define, b4_get_percent_code): Rename to...
1489 (b4_percent_define_get, b4_percent_code_get): ... these.
1490 Extend documentation with examples.
1491 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
1492 b4_percent_define_skeleton_variables and
1493 b4_percent_code_skeleton_qualifiers.
1494 Expect any value for the %define variable `foo' to be stored in the
1495 macro named `b4_percent_define(foo)'; expect any %code blocks for the
1496 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
1497 expect any unqualified %code blocks to be stored in a macro named
1498 `b4_percent_code_unqualified'.
1499 Use m4_indir so that %define variable names and %code qualifiers can
1500 contain `.', which is allowed by the grammar parser.
1501 (b4_percent_define_default): New macro to set a default value for a
1503 (m4_wrap): Update wrapped code, and fix some underquoting.
1504 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
1505 Expect grammar uses of %define variables and %code qualifiers to be
1506 defined in b4_percent_define_user_variables and
1507 b4_percent_code_user_qualifiers.
1508 * data/c++.m4: Use b4_percent_define_default rather than
1509 m4_define_default. Fix some underquoting. Skeleton usage of %define
1510 variable define_location_comparison now implies skeleton usage of
1511 %define variable filename_type.
1512 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1513 data/push.c, data/yacc.c: Update macro names.
1514 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
1517 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
1519 DJGPP specific issues.
1521 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
1522 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
1524 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1526 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
1527 run parsers in all tests so that Valgrind is invoked during
1528 maintainer-check-valgrind.
1529 (Duplicate representation of merged trees): Free all semantic values.
1530 (Duplicated user destructor for lookahead): Likewise.
1532 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1534 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
1535 command-line prefix.
1536 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
1537 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
1538 miss Valgrind messages.
1539 (Exploding the Stack Size with Malloc): Likewise.
1541 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1543 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
1544 locals. Reported by Juan Manuel Guerrero at
1545 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
1546 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
1547 Fix some indentation also.
1548 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
1549 explaining this issue.
1551 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
1552 and Joel E. Denny <jdenny@ces.clemson.edu>
1554 Simplify union and prologue handling, and escape union and lex/parse
1555 params with digraphs.
1556 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
1557 values to the empty string since these are no longer guaranteed
1558 initialized by the front-end.
1559 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
1560 braces around b4_user_stype since this is no longer done by the
1562 * src/files.c, src/files.h (pre_prologue_obstack,
1563 post_prologue_obstack): Remove.
1564 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
1565 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
1566 with digraphs. This fixes lex params and parse params.
1567 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
1568 * src/output.c (prepare): Remove muscle insertion of the prologues.
1569 (output): Remove freeing of pre_prologue_obstack and
1570 post_prologue_obstack.
1571 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
1572 than prologue_augment for prologue parsing so you don't need prologue
1574 (grammar_declaration): For %union RHS, use `braceless' instead of
1575 "{...}" so that braces are already stripped and code is escaped with
1577 * src/reader.c (prologue_augment): Remove.
1578 (reader): Remove initialization of pre_prologue_obstack and
1579 post_prologue_obstack.
1580 * src/reader.h (prologue_augment): Remove.
1582 * data/c.m4: Remove stray parenthesis.
1584 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1586 Remove quotes from variables names in %define directives and from
1587 qualifiers in %code directives, and restrict the characters that are
1588 allowed in them to M4-friendly ones. For %define, continue to support
1589 the quoted form as a deprecated feature. Discussed starting at
1590 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
1591 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
1593 * doc/bison.texinfo (Prologue Alternatives): Update.
1594 (Decl Summary): In %defines entry, update mention of `%code requires'
1595 and `%code provides'.
1596 (C++ Location Values): Update %define uses.
1597 (Calc++ Parser Interface): Likewise.
1598 (Calc++ Parser): Likewise, and update `%code requires' uses.
1599 (Table of Symbols): Update %code documentation.
1600 * src/parse-gram.y (prologue_declaration): For %define variables, use
1601 `variable' instead of `STRING'.
1602 (grammar_declaration): For %code qualifiers, use `ID' instead of
1604 (variable): New nonterminal that takes an `ID' or a `STRING'.
1605 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
1607 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
1608 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
1609 (%define errors): Update %define uses.
1611 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1613 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
1614 instead of muscle_insert for %define values so that M4-special
1615 characters are replaced with digraphs.
1616 * tests/input.at (%define errors): Extend to check weird values.
1618 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1620 Instead of having skeletons declare all valid %define variables and
1621 %code qualifiers, provide macros that retrieve the associated values
1622 and build these lists automatically. Thus Bison will now warn when a
1623 variable or qualifier is not used by the skeleton in the current
1624 invocation regardless of whether it might sometimes be used by that
1625 skeleton in other invocations. Also, move all %define value macros to
1626 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
1627 form, which is replaced by %code.
1628 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
1629 (b4_check_user_names): ... this, and change the series of valid name
1630 arguments to a single list argument for names used in the skeleton
1631 similar to the existing list argument for names used in the grammar.
1632 Warn instead of complaining.
1633 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
1634 values and %code code, to format %code code properly, and to build
1635 lists of all %define variables and %code qualifiers used in the
1636 skeleton: b4_skeleton_percent_define_variables and
1637 b4_skeleton_percent_code_qualifiers.
1638 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
1640 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
1641 the skeleton names lists can finish building first. In place of
1642 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
1643 expect the lists b4_user_percent_define_variables and
1644 b4_user_percent_code_qualifiers.
1645 * data/c++.m4: Where setting default values for b4_parser_class_name,
1646 b4_location_type, b4_filename_type, b4_namespace, and
1647 b4_define_location_comparison, update their names to the
1648 b4_percent_define_ namespace.
1649 * data/glr.c: Don't use b4_check_percent_define_variables and
1650 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
1651 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
1652 (b4_parser_class_name, b4_namespace): Define these using
1653 b4_get_percent_define for parser_class_name and namespace.
1654 * data/location.cc: Use b4_get_percent_define.
1655 * data/push.c: Don't use b4_check_percent_define_variables and
1656 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
1657 * data/yacc.c: Likewise, and don't call m4_exit in
1658 b4_use_push_for_pull_if or m4_wrap code will never execute.
1659 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
1661 (muscle_grow_user_name_list): ... this for consistency with the
1662 terminology used in bison.m4.
1663 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
1664 %define variable names, and rename muscle used_percent_define_variables
1665 to user_percent_define_variables.
1666 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
1667 user_percent_code_qualifiers.
1669 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
1670 {CODE} form is no longer accepted.
1671 * tests/input.at (Reject bad %code qualifiers): Rename to...
1672 (Reject unused %code qualifiers): ... this, and update test output.
1673 (%define error): Update test output.
1675 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
1677 Check for unrecognized %define variables similar to checking for
1678 unrecognized %code qualifiers. Check for redefined %define variables.
1679 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
1681 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
1682 (b4_check_percent_define_variables): New, also wraps it.
1683 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
1684 variables using b4_check_percent_define_variables.
1685 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
1686 all those exercised in the test suite and all those listed in the
1687 `Default values' section of c++.m4. Are there others?
1688 * data/push.c, data/yacc.c: Declare no valid %define variables.
1689 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
1690 similar to muscle_find, but it works even when the muscle stores a
1692 (muscle_grow_used_name_list): New function for constructing the used
1693 name list muscles that b4_check_for_unrecognized_names requires.
1694 * src/parse-gram.y (prologue_declaration): Warn if a variable is
1695 %define'd more than once. Define the b4_used_percent_define_variables
1696 muscle with muscle_grow_used_name_list.
1697 (grammar_declaration): Abbreviate %code code with
1698 muscle_grow_used_name_list.
1699 * tests/input.at (%define errors): New.
1701 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
1703 Provide warn_at, complain_at, and fatal_at function callbacks to the
1704 skeletons, and use this for %code qualifier complaints.
1705 * data/bison.m4 (b4_error_at): New, invoked by...
1706 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
1707 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
1708 @fatal_at(...@) directives.
1709 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
1710 qualifiers in b4_used_percent_code_qualifiers and to use
1712 * src/location.c, src/location.h (boundary_set_from_string): New global
1714 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
1716 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
1717 to b4_used_percent_code_qualifiers.
1718 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
1720 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
1721 (lineno): Rename to...
1722 (out_lineno): ... this so I don't misunderstand it again.
1723 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
1724 here; these newlines are in the input but not the output file.
1725 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
1726 (at_directive_perform): ... this new static function, and add handling
1727 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
1729 * tests/input.at (Reject bad %code qualifiers): Update test output with
1730 locations and extend.
1732 * tests/output.at (Output file name: [, Output file name: ]): Remove
1733 bogus comment about these tests failing.
1735 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
1737 Clean up b4_check_percent_code_qualifiers a little.
1738 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
1739 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
1740 documentation and add examples.
1741 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
1744 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
1746 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
1747 unreliable -- especially when they're hidden inside another macro.
1748 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
1749 data/c.m4: Remove m4_divert(-1).
1750 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1751 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
1752 m4_divert_push(0) and m4_divert_pop(0).
1753 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
1754 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
1755 pushed and popped by m4sugar, should be first on the stack.
1757 Provide warn, complain, and fatal function callbacks to the skeletons.
1758 This provides more flexibility than m4_fatal, improves the error
1759 message format, and captures messages for translation. Discussed
1761 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
1762 * data/bison.m4 (b4_error): New, invoked by...
1763 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
1764 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
1765 directives. Because these M4 macros might be called when the current
1766 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
1767 the previous removal of uses of m4_divert, which caused trouble.
1768 (b4_check_percent_code_qualifiers): Use b4_complain instead of
1769 m4_fatal to report unrecognized %code qualifiers.
1770 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
1771 push parser requests.
1772 * data/glr.c: Use b4_complain instead of m4_fatal to report
1773 non-deterministic push parser requests.
1774 Update @output usage to @output(...@) form.
1775 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
1776 report missing %defines. Update @output usage to @output(...@) form.
1777 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
1779 * src/main.c (main): Invoke skel_scanner_free.
1780 * src/scan-skel.h (skel_scanner_free): Prototype new function.
1781 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
1782 obstack_for_string from flex-scanner.h.
1783 (YY_DECL): Use to declare skel_lex static.
1784 (decode_at_digraphs): Remove; now handled in the new
1785 SC_AT_DIRECTIVE_ARG start condition.
1786 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
1788 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
1789 at_directive_argv): New static globals.
1790 (INITIAL): Use fail_for_invalid_at.
1791 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
1792 recognize the start of a generalized `@directive(...@)' form and
1794 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
1795 directive args (using the new obstack_for_string), to decode the
1796 contained @ diagraphs, and to perform the directive. It recognizes
1797 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
1799 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
1800 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
1802 (scan_skel): Initialize obstack_for_string on the first call.
1803 (skel_scanner_free): New function to free obstack_for_string.
1804 * tests/input.at (Reject bad %code qualifiers): Update test output.
1806 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
1808 Consolidate the 4 prologue alternative directives (%code, %requires,
1809 %provides, and %code-top) into a single %code directive with an
1810 optional qualifier field. Discussed at
1811 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
1812 * NEWS (2.3a+): Rewrite the existing entry for the prologue
1814 * doc/bison.texinfo (Prologue Alternatives): Update.
1815 (Decl Summary): Update to %code "requires" and %code "provides".
1816 (Calc++ Parser): Update to %code "requires".
1817 (Table of Symbols): Remove entries for %requires, %provides, and
1818 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
1819 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
1820 are replaced by b4_percent_code_provides and b4_percent_code_requires,
1821 which are skeleton-specific.
1822 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
1823 declare what %code qualifiers it supports and to complain if any other
1824 qualifiers were used in the grammar.
1825 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
1826 and b4_user_code([b4_percent_code_provides]) in place of
1827 b4_user_requires and b4_user_provides.
1828 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
1829 Add b4_user_code([b4_percent_code_top]) and
1830 b4_user_code([b4_percent_code]).
1831 Invoke b4_check_percent_code_qualifiers.
1832 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
1833 PERCENT_REQUIRES): Remove.
1834 (grammar_declaration): Remove RHS's for %code-top, %provides, and
1835 %requires. Rewrite the %code RHS as the unqualified form defining the
1836 muscle b4_percent_code. Add another RHS for the qualified %code form,
1837 which defines muscles of the form b4_percent_code_QUALIFIER and the
1838 b4_used_percent_code_qualifiers muscle.
1839 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
1840 PERCENT_REQUIRES): Remove.
1841 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
1842 %code "requires" and %code "provides".
1843 * tests/input.at (Reject bad %code qualifiers): New.
1845 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
1847 Use the new code_props interface for destructors and printers.
1848 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
1849 printer_location members, and change the type of the destructor and
1850 printer members to code_props.
1851 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
1852 symbol_printer_get, semantic_type_destructor_set,
1853 semantic_type_printer_set, default_tagged_destructor_set,
1854 default_tagless_destructor_set, default_tagged_printer_set,
1855 default_tagless_printer_set): Use code_props in arguments and return
1856 types in place of char const * and location.
1857 (symbol_destructor_location_get, symbol_printer_location_get): Remove
1858 since the locations are now contained in the return of
1859 symbol_destructor_get and symbol_printer_get.
1860 * src/output.c (symbol_destructors_output, symbol_printers_output):
1862 (symbol_code_props_output): ... this to eliminate duplicate code.
1863 (output_skeleton): Update to use symbol_code_props_output.
1864 * src/reader.c (symbol_should_be_used): Update use of
1865 symbol_destructor_get.
1866 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
1867 Update uses of the various _destructor_set and _printer_set functions.
1868 * src/symtab.c: (default_tagged_destructor_location,
1869 default_tagless_destructor_location, default_tagged_printer_location,
1870 default_tagless_printer_location): Remove since we...
1871 (default_tagged_destructor, default_tagless_destructor,
1872 default_tagged_printer, default_tagless_printer): ... change the type
1873 of these to code_props.
1874 (symbol_new, semantic_type_new, symbol_destructor_set,
1875 semantic_type_destructor_set, symbol_destructor_get,
1876 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
1877 symbol_check_alias_consistency, default_tagged_destructor_set,
1878 default_tagless_destructor_set, default_tagged_printer_set,
1879 default_tagless_printer_set): Update.
1880 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
1881 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
1883 (symbol_print): Use SYMBOL_CODE_PRINT.
1885 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
1887 Use the new code_props interface for rule actions.
1888 * src/symlist.h (symbol_list): Replace action, action_location, and
1889 used members with a code_props action_props member.
1890 * src/reader.c (symbol_should_be_used, grammar_rule_check,
1891 grammar_midrule_action, grammar_current_rule_merge_set,
1892 grammar_current_rule_symbol_append, packgram): Update.
1893 * src/scan-code.h (translate_rule_action): Remove, no longer used.
1894 * src/scan-code.l (handle_action_dollar): Update.
1895 (translate_rule_action): Remove, no longer used.
1896 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
1898 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
1900 Use the new code_props interface in parse-gram.y.
1901 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
1902 Update all uses of translate_* functions to use the new code_props
1903 interface and to use gram_scanner_last_string_free and
1904 code_scanner_last_string_free where possible.
1905 (grammar_declaration): symbol_list_destructor_set and
1906 symbol_list_printer_set now perform the translation, so don't do it
1907 here. Use gram_scanner_last_string_free where possible.
1908 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
1909 translate_code): Remove, no longer used.
1910 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
1911 symbol_list_printer_set): Perform code translation here rather than
1912 depending on the caller to do so.
1914 * src/symlist.h (struct symbol_list): Correct some documentation typos.
1915 * src/scan-gram.h (gram_last_string): Remove declaration.
1916 * src/scan-gram.l (last_string): Declare it static.
1918 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
1920 Encapsulate code properties and related functionality for the various
1921 destructors, printers, and actions into a code_props structure and
1922 interface. This patch merely implements code_props in scan-code.h and
1923 scan-code.l. Future patches will rewrite other modules to use it.
1924 Discussed starting at
1925 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
1926 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
1927 consistently initialize const structs that have an empty location
1929 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
1930 to ensure consistency.
1931 * src/scan-code.h (code_props): New structure.
1932 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
1933 function, macro, and const global variable for initializing a
1934 code_props with no code.
1935 (code_props_plain_init, code_props_symbol_action_init,
1936 code_props_rule_action_init, code_props_translate_code): The rest of
1937 the new code_props functional interface. Among other things, the init
1938 functions set the code_props kind field so that
1939 code_props_translate_code will know whether to behave like
1940 translate_symbol_action, translate_rule_action, or translate_code.
1941 These old translate functions must remain until all other modules are
1942 updated to use the new code_props interface.
1943 (code_scanner_last_string_free): New function similar to
1944 gram_scanner_last_string_free.
1945 (code_scanner_free): Add documentation.
1946 * src/scan-code.l: Implement the new interface.
1947 (code_lex): Make it static, add a code_props* argument, and remove the
1949 (last_string): New static global similar to the one in scan-gram.l.
1950 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
1952 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
1953 code_props since Bison may one day use this information for destructors
1955 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
1956 (handle_action_dollar): Use symbol_list_n_get and set used flag
1957 directly since symbol_list_n_used_set is removed.
1958 (translate_action): Add a code_props* argument and remove the rule,
1959 action, and location arguments. Pass the code_props* on to code_lex.
1960 (translate_rule_action, translate_symbol_action, translate_code):
1961 Rewrite as wrappers around the new code_props interface.
1962 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
1963 it would eventually need to break the encapsulation of code_props.
1965 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
1967 * etc/.cvsignore: New.
1969 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
1971 Add maintainer-push-check to run maintainer-check using push parsing in
1972 place of pull parsing where available.
1973 * Makefile.am (maintainer-push-check): New.
1974 * data/bison.m4 (b4_use_push_for_pull_if): New.
1975 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
1976 appropriately based on their existing values.
1977 (yypush_parse): Don't print push-parser-specific diagnostics if push
1978 parsing is being used in place of pull parsing.
1979 * data/yacc.c: If push parsing should replace pull parsing, redirect to
1981 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
1982 variable, and insert b4_use_push_for_pull_flag into muscles.
1983 * tests/Makefile.am (maintainer-push-check): New.
1985 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
1987 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
1988 (whether successful or failed) so that yypush_parse can be invoked
1989 again to start a new parse using the same yypstate.
1990 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
1991 check multiple yypull_parse invocations on the same yypstate. For pull
1992 mode, extend to check multiple yyparse invocations.
1993 (Exploding the Stack Size with Alloca): Extend to try with
1995 (Exploding the Stack Size with Malloc): Likewise.
1997 * tests/calc.at (Simple LALR Calculator): Don't specify
1998 %skeleton "push.c" since %push-pull-parser implies that now.
1999 * tests/headers.at (export YYLTYPE): Don't check for the push
2000 declarations. Otherwise, this test case can't be used to see if push
2001 mode can truly emulate pull mode.
2002 * tests/input.at (Torturing the Scanner): Likewise.
2003 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
2004 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
2005 AT_YACC_IF, which now includes the case of push mode since %skeleton
2006 need not be used for push mode. This will be more intuitive once
2007 push.c is renamed to yacc.c.
2009 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2011 For push mode, convert yyparse from a macro to a function, invoke yylex
2012 instead of passing a yylexp argument to yypull_parse, and don't
2013 generate yypull_parse or yyparse unless %push-pull-parser is declared.
2014 Discussed starting at
2015 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
2016 * data/bison.m4 (b4_pull_if): New.
2017 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
2018 * data/push.c: Improve M4 quoting a little.
2019 (b4_generate_macro_args, b4_parenthesize): Remove.
2020 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
2021 any time a pull parser is requested.
2022 Don't #define this as a wrapper around yypull_parse. Instead, when
2023 both push and pull are requested, make it a function that does that
2025 (yypull_parse): If there's a b4_prefix, #define this to
2026 b4_prefix[pull_parse] when both push and pull are requested.
2027 Don't define this as a function unless both push and pull are
2029 Remove the yylexp argument and hard-code yylex invocation instead.
2030 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
2032 * src/getargs.c (pull_parser): New global initialized to true.
2033 * getargs.h (pull_parser): extern it.
2034 * src/output.c (prepare): Insert pull_flag muscle.
2035 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
2036 (prologue_declaration): Set both push_parser and pull_parser = true for
2037 %push-pull-parser. Set push_parser = true and pull_parser = false for
2039 * src/scan-gram.l: Don't accept %push_parser as an alternative to
2040 %push-parser since there's no backward-compatibility concern here.
2041 Scan %push-pull-parser.
2042 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
2043 instead of %push-parser.
2044 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
2045 prototype it in the module that calls yyparse.
2046 * tests/input.at (Torturing the Scanner): Likewise.
2047 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
2049 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
2051 Update etc/bench.pl. Optimize push mode a little (the yyn change
2052 deserves most of the credit).
2053 * Makefile.am (SUBDIRS): Add etc subdirectory.
2054 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
2055 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
2056 yytoken, yyval, and yyloc declarations to...
2057 (yyparse or yypush_parse): ... here to improve performance. For
2058 yypush_parse invocations after the first, be sure to assign yyn its old
2060 (yypstate_new): Don't bother initializing the yyresult field since the
2061 initial value isn't used.
2062 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
2063 remove the #define that, in push mode, set it to yyps->NAME.
2064 * etc/Makefile.am: New.
2065 * etc/bench.pl: Remove and build it instead from...
2066 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
2067 "tests/bison" from the build directory by default rather than just
2068 invoking "bison" from $PATH.
2069 (calc_grammar): Update push parser code: don't declare yylval globally,
2070 don't define yyparse_wrapper, and don't #define yyparse.
2071 (bench_grammar): Update to check all working combinations of yacc.c,
2072 push.c, impure, pure, pull, and push.
2074 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2076 For push mode, add pull wrappers around yypush_parse.
2077 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
2078 (yypull_parse): New function wrapping yypush_parse.
2079 (yyparse): New #define wrapping yypull_parse.
2080 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
2082 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
2083 prototype yylex in the module that calls yyparse, and don't prototype
2084 yyparse there. Otherwise, the yyparse expansion won't compile.
2085 * tests/input.at (Torturing the Scanner): Likewise.
2087 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2089 Enable push parsers to operate in impure mode. Thus, %push-parser no
2090 longer implies %pure-parser. The point of this change is to move
2091 towards being able to test the push parser code by running the entire
2092 test suite as if %push-parser had been declared.
2093 * data/push.c (yypush_parse): For impure mode, remove the
2094 yypushed_char, yypushed_val, and yypushed_loc arguments.
2095 Instead, declare these as local variables initialized to the global
2096 yychar, yylval, and yylloc.
2097 For the first yypush_parse invocation only, restore the initial values
2098 of these global variables when it's time to read a token since they
2099 have been overwritten.
2100 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
2102 * tests/calc.at (Simple LALR(1) Calculator): Always declare
2103 %pure-parser along with %push-parser since this test case was designed
2104 for pure push parsers.
2105 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
2106 (AT_YACC_OR_PUSH_IF): New.
2107 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
2108 add a note that it's still wrong for some cases (as it has been for a
2110 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
2111 %push-parser no longer implies %pure-parser.
2113 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2115 Remove some unnecessary differences between the pull parser code and
2116 the push parser code. This patch enables yynerrs in push mode.
2117 * data/push.c: Reformat M4 a little.
2118 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
2119 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
2120 because push mode is on. Instead, if pure mode is on, move yynerrs
2122 (b4_declare_parser_state_variables): ... here.
2123 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
2124 to yyps->NAME so it can be used in yypush_parse.
2125 (yypush_parse): Don't omit uses of yynerrs in push mode.
2127 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2129 Fix bug such that the first pushed token's value and location are
2130 sometimes overwritten (sometimes by %initial-action) before being used.
2131 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
2132 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
2133 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
2134 more closely mimic the pull parser logic.
2135 Don't copy the pushed token to yychar, yylval, and yylloc until it's
2136 time to read a token, which is after any initialization of yylval and
2138 (gottoken): Rename label to...
2139 (yyread_pushed_token): ... for clarity and to avoid infringing on the
2142 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2144 Rearrange initialization of the parser state variables so that the
2145 skeleton doesn't have to have a copy for pull mode and another for push
2146 mode. This patch also fixes at least a bug such that yylloc was not
2147 initialized (with b4_location_initial_line and
2148 b4_location_initial_column) upon calling yypush_parse. However, that
2149 initialization now overwrites the first token's location;
2150 %initial-action assigning @$ already did the same thing, and both bugs
2151 will be fixed in a later patch.
2152 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
2153 (b4_declare_parser_state_variables): Remove initialization of yytoken,
2154 yyss, yyvs, yyls, and yystacksize.
2155 (yypstate_new): Remove initialization of some yypstate fields: yystate,
2156 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
2158 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
2159 yyps->NAME so it can be used in yypush_parse.
2160 (yyparse or yypush_parse): For yypush_parse, don't print the
2161 "Starting parse" diagnostic for invocations after the first.
2162 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
2163 yypush_parse, only do it for the first invocation.
2164 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
2165 initialization to occur in yypush_parse but only on the first
2168 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2170 * data/push.c: Add CPP guards around push parser declarations in both
2171 the header and the code file.
2172 In the code file, move the push parser declarations to the same place
2173 they appear in the header file.
2174 Clean up the M4 some, especially the inconsistent underquoting in
2175 some b4_c_function_def and b4_c_function_decl uses.
2177 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2179 Encapsulate the push parser state variables into an M4 macro so the
2180 push skeleton doesn't have to list them again for pull mode's yyparse.
2181 For push mode, remove yypush_parse's local equivalents of these
2182 variables to eliminate unnecessary copying between the two sets at
2183 run-time. This patch also fixes at least a bug related to multiple
2184 %initial-action invocations in push mode.
2185 * data/push.c (b4_declare_parser_variables): Rename to...
2186 (b4_declare_scanner_communication_variables): ... this for clarity and
2188 (b4_declare_yyparse_variables): Remove and move its contents to the one
2189 spot where it was invoked.
2190 (b4_declare_parser_state_variables): New macro containing the parser
2191 state variables required by push mode.
2192 (struct yypstate): Replace all fields but yynew with
2193 b4_declare_parser_state_variables.
2194 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
2195 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
2196 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
2197 (yyparse or yypush_parse): For yyparse in pull mode, replace local
2198 parser state variable declarations with
2199 b4_declare_parser_state_variables.
2200 Don't initialize parser state variables when calling yypush_parse since
2201 yypstate_new already does that.
2202 Invoke the user's initial action only upon the first yypush_parse
2204 Remove all code that copies between the local parser state variables
2207 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2209 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
2210 prevent a name collision in a future patch where these names will
2211 sometimes be #define'd.
2212 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
2213 since it no longer has the same name as the existing argument.
2214 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
2216 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
2217 and Joel E. Denny <jdenny@ces.clemson.edu>
2219 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
2220 that the argument is case-insensitive, and there's no `=' here.
2221 For the %skeleton entry, mention that %language is better.
2222 (Bison Options): Likewise for --language and --skeleton. Move the
2223 --skeleton entry so that the `Tuning the parser' section is sorted
2224 alphabetically on long options.
2225 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
2226 %language directive in detail here; cross-reference the %language
2227 documentation instead.
2228 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
2229 `%require "2.3b"' so that the example is always up-to-date.
2230 (Table of Symbols): Add entries for %language and %skeleton.
2231 * examples/extexi (normalize): Instead of replacing every %require
2232 argument with the current Bison version, just substitute for
2233 `@value{VERSION}'. This guarantees that we're testing what actually
2234 appears in the documentation.
2235 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
2236 rather than `@VERSION@'.
2238 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2240 * NEWS: Reword the %language news a bit, and put it earlier.
2242 * src/getargs.c (skeleton_arg): Last arg is now location const *.
2243 Rewrite to simplify the logic.
2244 (language_argmatch): Likewise.
2245 (program_name): We now own this var.
2246 * src/getargs.h (struct bison_language): Use char[] rather than
2249 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
2251 * src/complain.c (program_name): Remove decl; no longer needed.
2252 * src/main.c (program_name): Remove; now belongs to getargs.
2254 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
2256 * NEWS: Document %language.
2258 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
2260 * data/c-skel.m4, data/c++-skel.m4: New files.
2261 * data/glr.c: Complain on push parsers.
2263 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
2265 (Decl Summary): Document %language and %skeleton.
2266 (Command line): Document -L.
2268 * examples/extexi: Rewrite %require directive.
2269 * examples/calc++/Makefile.am: Pass VERSION to extexi.
2271 * src/files.c (compute_exts_from_gc): Look in language structure
2273 (compute_file_name_parts): Check whether .tab should be added.
2274 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
2275 (language, skeleton_arg, language_argmatch): New.
2276 (long_options): Add --language.
2277 (getargs): Use skeleton_arg, add -L/--language.
2278 * src/getargs.h: Include location.h.
2279 (struct bison_language, language, skeleton_arg, language_argmatch): New.
2280 * src/output.c (prepare): Pick default skeleton from struct language.
2281 Don't dispatch C skeletons here.
2282 * src/parse-gram.y (PERCENT_LANGUAGE): New.
2283 (prologue_declaration): Add "%language" rule, use skeleton_arg.
2284 * src/scan-gram.l ("%language"): New rule.
2286 * tests/calc.at: Test %skeleton and %language.
2287 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
2288 (AT_GLR_IF): Look for %skeleton "glr.cc".
2289 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
2290 (AT_YACC_IF): Reject %language.
2292 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2294 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
2295 since it wasn't used; only the typedef name 'semantic_type' is needed.
2296 Also, omit trailing white space.
2298 * bootstrap: Sync from coreutils.
2299 (gnulib_extra_files): Add build-aux/announce.gen.
2300 (slurp): Adjust .gitignore files like .cvsignore files.
2301 * build-aux/announce-gen: Remove from CVS, since bootstrap
2304 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
2306 Make %push-parser imply %pure-parser. This fixes several bugs; see
2307 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
2308 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
2310 * data/push.c: Don't bother testing b4_push_if when deciding whether
2311 to expand b4_declare_parser_variables globally.
2312 (yypush_parse): Likewise in here.
2314 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
2315 (yy_reduce_print): Reformat M4 for readability.
2317 2006-12-15 Bob Rossi <bob@brasko.net>
2318 and Joel Denny <jdenny@ces.clemson.edu>
2320 * data/push.c (yypstate): Add typedef, and update all uses of
2321 struct yypstate to just yypstate.
2322 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
2324 2006-12-14 Bob Rossi <bob@brasko.net>
2326 * data/push.c (yypush_parse): Declare prototype regardless of
2329 2006-12-14 Bob Rossi <bob@brasko.net>
2331 * data/push.c (yyparse): Remove the prototype and the #define when in
2334 2006-12-13 Bob Rossi <bob@brasko.net>
2336 * data/push.c (yypstate_init): Rename to...
2337 (yypstate_new): ... this and use b4_c_function_def.
2338 (yypstate_delete): New.
2339 (yypush_parse): Change parameters yynval and yynlloc to be const.
2340 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
2341 yypstate_delete functions.
2343 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
2345 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
2346 strange test case titles. Reported by Bob Rossi.
2348 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
2350 * TODO: Add pointer to Sylvain Schmitz's work on static detection
2351 of potential ambiguities in GLR grammers.
2353 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
2355 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
2356 `bison ', use m4_index instead of m4_substr since chopping up a string
2357 containing M4-special characters causes problems here.
2359 Fix a couple of bugs related to special characters in user-specified
2360 file names, and make it easier for skeletons to compute output file
2361 names with the same file name prefix as Bison-computed output file
2363 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
2364 b4_parser_file_name and b4_spec_defines_file instead of
2365 @output_parser_name@ and @output_header_name@, which are now redundant.
2366 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
2367 b4_parser_file_name, b4_spec_defines_file, and the new
2368 @basename(FILENAME@) instead of @output_parser_name@ and
2369 @output_header_name@, which inappropriately escaped the file names as
2371 * src/files.c (all_but_ext): Remove static qualifier.
2372 (compute_output_file_names): Move `free (all_but_ext)' to...
2373 (output_file_names_free): ... here since all_but_ext is needed later.
2374 * src/files.h (all_but_ext): Extern.
2375 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
2376 exactly what MUSCLE_INSERT_STRING used to do.
2377 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
2378 characters are escaped properly.
2379 * src/output.c (prepare): Define muscle file_name_all_but_ext as
2381 For pkgdatadir muscle, maintain previous functionality by using
2382 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
2383 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
2384 digraphs would never be expanded. Hopefully no one has M4-special
2385 characters in his Bison installation path.
2386 * src/scan-skel.l: Don't parse @output_header_name@ and
2387 @output_parser_name@ anymore since they're now redundant.
2388 In @output, use decode_at_digraphs.
2389 Parse a new @basename command that invokes last_component.
2390 (decode_at_digraphs): New.
2391 (BASE_QPUTS): Remove unused.
2392 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
2393 (Output file name): New tests.
2395 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
2397 Warn about output files that are generated by the skeletons and that
2398 conflict with other output files.
2399 * data/glr.c: Don't generate the header file here when glr.cc does.
2400 * src/files.c (file_names, file_names_count): New static globals.
2401 (compute_output_file_names): Invoke output_file_name_check for files
2402 not generated by the skeletons and remove existing checks.
2403 (output_file_name_check): New function that warns about conflicting
2405 (output_file_names_free): Free file_names.
2406 * src/files.h (output_file_name_check): Declare.
2407 * src/scan-skel.l: Invoke output_file_name_check for files generated by
2409 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
2410 (Conflicting output files): New tests.
2412 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2414 * doc/bison.texinfo: Fix a couple of typos.
2416 2006-12-08 Bob Rossi <bob@brasko.net>
2418 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
2420 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
2422 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
2423 (yypush_parse): Rename yypvars argument to yyps and remove redundant
2425 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
2426 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
2428 2006-12-07 Bob Rossi <bob@brasko.net>
2429 and Joel Denny <jdenny@ces.clemson.edu>
2431 * data/push.c (yypvarsinit): Change return type from void* to struct
2432 yypvars*. No longer cast to void* on return.
2433 (struct yypvars): Remove yylen since it need not be remembered between
2434 yypushparse invocations.
2435 (yypushparse): Don't copy between yylen and pv->yylen.
2437 2006-12-05 Bob Rossi <bob@brasko.net>
2439 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
2440 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
2441 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
2442 (struct yypvars): Remove b4_declare_parser_variables.
2443 (yypvarsinit): Remove init code for removed variables.
2444 (global scope): Do not declare b4_declare_parser_variables if
2446 (yypushparse): Add b4_declare_parser_variables.
2447 Init new local variables, and remove init code for removed
2450 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
2451 and yyparse for other modes.
2452 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
2453 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
2454 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
2455 (AT_PURE_LEX_IF): True if pure or push parser.
2457 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
2459 Document Yacc prologue alternatives and default %destructor's and
2460 %printer's as experimental. Don't mention Java yet. Discussed at
2461 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
2462 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
2463 (2.3a): Annotate this entry to say the old forms of these features were
2465 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,

2467 of Java (we'll want this back eventually).
2469 2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
2471 Support a file name argument to %defines. Deprecate `=' in
2472 %file-prefix, %name-prefix, and %output. Discussed at
2473 <http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
2474 * NEWS (2.3a+): Mention.
2475 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
2476 form of %defines, and remove `=' from entries for %file-prefix,
2477 %name-prefix, and %output.
2478 * src/parse-gram.y (prologue_declaration): Implement.
2479 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
2480 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
2481 all but one occurrence of %name-prefix.
2482 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
2483 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
2484 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
2485 occurrence of each of %file-prefix and %output. Add check for %defines
2487 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
2488 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
2489 Remove the `=' from %output.
2491 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
2493 Don't escape $ in test case titles since Autoconf 2.61 now does that
2495 * tests/actions.at (Default %printer and %destructor are not for error
2496 or $undefined): Here.
2497 (Default %printer and %destructor are not for $accept): Here.
2498 * tests/input.at (Invalid $n and @n): Here.
2500 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
2502 Rename <!> to <>. Discussed starting at
2503 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
2504 * NEWS (2.3a+): Update.

2512 * tests/actions.at (Default tagless %printer and %destructor,
2513 Default tagged and per-type %printer and %destructor,
2514 Default %printer and %destructor are not for error or $undefined,
2515 Default %printer and %destructor are not for $accept,
2516 Default %printer and %destructor for mid-rule values): Update.
2517 * tests/input.at (Default %printer and %destructor redeclared,
2518 Unused values with default %destructor): Update.
2520 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
2522 Don't let %prec take a nonterminal.
2523 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
2525 * tests/input.at (%prec takes a token): New test checking that %prec
2526 won't take a nonterminal.
2528 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
2530 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
2531 it was double-quoted.
2532 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
2533 grammar is maintained with Bison's highest standards.
2534 * src/getargs.c: Fix some typos in Doxygen comments.
2536 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
2538 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
2539 later. Reported by Paul Eggert in
2540 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
2541 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
2542 * src/scan-code.l (translate_action): Don't bother invoking
2543 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
2544 (code_scanner_free): Instead of invoking
2545 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

2553 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
2554 has been called previously for the same key.
2555 (muscle_find): Return storage instead of value so that
2556 --enable-gcc-warnings doesn't produce warnings that the return discards
2557 const. aver that the value and storage are the same since storage
2558 could potentially be NULL when value is not.
2559 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
2562 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2564 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
2565 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
2566 us a slightly cleaner distribution, and also works.
2567 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
2570 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
2571 and Paul Eggert <eggert@cs.ucla.edu>

2574 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
2575 (spec_defines_file, dir_prefix): Now char *, not const char *,
2576 since they are freed.
2577 * src/files.c: Likewise.
2578 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
2580 (tr): Now operates in-place. All uses changed.
2581 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
2583 (compute_file_name_parts, compute_output_file_names): Don't store
2584 read-only data in variables that will be freed.
2585 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
2586 src_extension, and header_extension.
2587 (output_file_names_free): New public function to free
2588 spec_verbose_file, spec_graph_file, spec_defines_file,
2589 parser_file_name, and dir_prefix.
2590 * src/getargs.c (getargs): Don't store read-only data in variables that
2592 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
2593 (which previously existed but was unused), and quotearg_free.
2594 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
2595 * src/muscle_tab.c: Likewise.
2596 (muscle_entry): Make the value char const *,
2597 and add a new storage member that is char * and can be freed.
2598 (muscle_entry_free): New private function.
2599 (muscle_init): Use it instead of free.
2600 (muscle_insert, muscle_grow): Update and use new storage member.
2601 (muscle_code_grow): Free the string passed to muscle_grow
2602 since it's not needed anymore.
2603 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
2604 add a new `char *code' member.
2605 ("{...}"): Declare semantic type as code.
2606 * src/scan-code.h (translate_rule_action):
2607 (translate_symbol_action, translate_code, translate_action): Return
2608 `char const *' rather than `char *' since external code should not free
2610 * src/scan-code.l: Likewise.
2611 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
2612 which is "{...}" in the parser.
2613 * tests/Makefile.am (maintainer-check-valgrind): Set
2614 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
2616 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
2618 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
2619 expecting a non-zero exit status sets --leak-check=summary and
2620 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
2621 this case, and we don't want to hear about it.
2623 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2625 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
2626 instead of from the template, to simplify configuration a bit.

2632 Disable unset/unused mid-rule value warnings by default, and recognize
2633 --warnings=midrule-values to enable them. Discussed starting at

2637 warnings): Add entry for midrule-values subargument.
2638 * src/reader.c (symbol_should_be_used): Don't return true just because
2639 the value is a set/used mid-rule value unless
2640 --warnings=midrule-values was specified.
2641 * tests/input.at (Unused values, Unused values before symbol
2642 declarations): Run tests with and without --warnings=midrule-values.
2644 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
2645 than LIST_FREE directly.
2647 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
2649 Finish implementing --warnings=error, which should not be implied by

2666 empty subargument list. For example: `bison --warnings= parser.y'.
2668 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
2670 * data/push.c, data/yacc.c: Make sure there's a newline at the end of

2675 Split the default %destructor/%printer into two kinds: <*> and <!>.
2676 Discussed starting at

2724 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
2725 like $@n instead of just @n so that the default %destructor/%printer
2726 logic doesn't see them as user-defined symbols.
2727 (symbol_is_dummy): Check for both forms of the name.
2728 * src/reader.c (packgram): Remove the `$' from each midrule symbol
2729 name for which the midrule value is referenced in any action.

2740 (packgram): Before invoking grammar_rule_check on any rule, make sure
2741 all actions have already been scanned in order to set `used' flags.
2742 Otherwise, checking that a midrule's $$ is set will not always work
2743 properly because the midrule check must forward-reference the midrule's
2745 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
2748 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
2750 More improvements to the documentation of the prologue alternatives:
2751 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
2753 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
2754 some text to clarify the relative importance of the new directives and
2755 to show how these directives may be viewed as code labels.
2757 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
2759 Similar to the recently removed %before-header, add %code-top as the
2760 alternative to the pre-prologue. Mentioned at
2761 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.

2827 Fix testsuite for ./configure --enable-gcc-warnings:
2828 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.

2872 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
2873 variable was sometimes used without being initialized. This
2874 messed up the installation of the INSTALL file in some cases.
2876 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2878 * bootstrap (usage, main program, symlink_to_gnulib): Add option
2879 --copy. Inspired by a suggestion from Bruno Haible.
2881 2006-10-03 Jim Meyering <jim@meyering.net>

2884 sticks with the automake default in generating dependencies.
2886 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2888 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

2964 and try to make such failures easier to catch in the future.
2965 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
2966 that's now the caller's responsibility.
2967 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
2968 Set yychar = YYEOF if it's negative.
2969 * tests/actions.at (yylex): Abort if asked to read past EOF.

2979 Fix problems with translating English-language diagnostics.
2980 * bootstrap: Fix bug introduced in recent bootstrap changes, with

2991 2006-09-28 Jim Meyering <jim@meyering.net>
2993 Automatically generated dependencies are important even
2994 when all of the sources in a directory come from gnulib.
2995 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
2996 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
2998 2006-09-23 Jim Meyering <jim@meyering.net>

3033 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
3034 to copies-of-gnulib.
3035 (cp_mark_as_generated, slurp, gnulib_files):
3036 Avoid making a copy if it's the same as the old version.
3037 (gnulib_files): Add support for this variable (used by Bison).
3039 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
3041 * src/getargs.c (usage): Rework to use conventions similar to
3042 coreutils, to make translation a bit easier and the code a bit
3043 smaller. Problem reported by Tim Van Holder.
3045 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
3047 Use some of gnulib's new modules, taken from coreutils.
3049 * bootstrap: Sync from coreutils, except add support for gnulib_files.
3050 * bootstrap.conf: New file.
3051 (gnulib_modules): Add configmake, inttypes, unistd.
3052 (XGETTEXT_OPTIONS): Add complain, complain_at,

3054 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
3055 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
3057 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
3059 (GNULIB_AUTOCONF_SNIPPET): Remove.
3060 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
3062 * lib/.cvsignore: Add inttypes_.h.
3063 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
3064 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
3065 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
3066 no-longer-necessary initializations.
3067 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.

3071 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,

3073 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
3074 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
3075 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
3076 * src/system.h: Include inttypes.h unconditionally, now that we
3077 use the inttypes module. Don't bother to include stdint.h, since
3078 inttypes.h now does that for us.

3080 * src/getargs.c: Include configmake.h.
3081 * src/main.c: Likewise.
3082 * src/output.c: Likewise.
3083 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,

3087 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
3088 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
3090 * src/parse-gram.y (symbol_declaration): Don't put statements
3091 before declarations; it's not portable to C89.
3092 * src/scan-code.l (handle_action_at): Likewise.
3094 * src/scan-code.l: Always initialize braces_level; the old code
3095 left it uninitialized and therefore had undefined behavior.
3097 Don't attempt to redefine 'assert', since it runs afoul of
3098 systems where standard headers (mistakenly) include <assert.h>.
3099 Instead, define and use our own alternative, called 'aver'.
3100 * src/reader.c: Don't include assert.h, since we no longer
3102 * src/scan-code.l: Likewise.
3103 * src/system.h (assert): Remove, replacing with....
3104 (aver): New function, taking a bool arg. All uses changed.

3110 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
3111 * data/c.m4 (YYPUSH): New.
3112 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
3113 * src/getargs.c (push_parser): New var.
3114 * src/getargs.h (push_parser): New declaration.
3115 * src/output.c (prepare): Add macro insertion of `push_flag'.
3116 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
3117 (prologue_declaration): Parse %push-parser.
3118 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
3119 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
3120 list of removed lines from the traces observed.
3121 (AT_CHECK_CALC_LALR): Added push parser tests.
3123 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
3125 * NEWS: Version 2.3a.
3126 * configure.ac (AC_INIT): Likewise.
3128 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
3129 "#define YYSTYPE int" that caused "make maintainer-check" to fail
3130 due to header ordering dependencies. I don't know why the #define
3133 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
3134 runtime cost when YYDEBUG is not defined, and so that some tests
3135 that used to fail now work. Problem and initial suggestion by
3137 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
3138 * data/glr.cc (b4_parser_class_name):
3139 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
3140 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
3141 (yydebug_) [YYDEBUG]: New member.
3142 (yycdebug_): Now defined only if YYDEBUG.
3143 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
3144 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
3145 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
3147 (debug_stream, set_debug_stream, debug_level, set_debug_level):
3148 Define only if YYDEBUG.
3149 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
3151 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
3152 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
3153 AT_CHECK_CALC_GLR_CC that are working now.
3155 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
3157 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
3158 We don't need them in glr.cc, and glr.c defines them.
3159 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
3160 assumes that defining it to anything is the same as defining
3161 it to 1. Problem reported by Paolo Bonzini.
3163 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
3165 * data/c.m4 (b4_null, b4_case): Define.
3166 * src/output.c (prepare_symbols): Use b4_null.
3167 (user_actions_output): Use b4_case.
3169 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
3171 * data/glr.c (b4_shared_declarations): Put start-header first,
3172 before any #includes that we generate, so that feature-test
3173 macros work. Problem reported by Michael Deutschmann in
3174 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
3175 * data/lalr1.cc: Likewise.
3176 * doc/bison.texinfo (Prologue): Document that feature-test macros
3177 should be defined before any Bison declarations.
3178 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
3179 that depend on location.hh after, not before, Bison decls, since
3180 we now include location.hh after the first user prologue.
3182 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
3183 Sander Brandenburg in
3184 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
3185 Also, fix minor white space and comment issues.
3186 (Prologue): Mention that it's better to define feature-test macros
3187 before Bison declarations. Problem reported by Michael Deutschmann.
3189 * README-cvs: Fix typo: "&" should be "&&". Problem reported
3191 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
3192 This adjusts to recent gnulib changes.
3194 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3196 Finish implementation of per-type %destructor/%printer. Discussed
3198 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
3200 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
3201 * NEWS (2.3+): Add a description of this feature to the default
3202 %destructor/%printer description.
3203 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
3204 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3205 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
3206 list node contains a semantic type.
3207 * src/symtab.c, src/symtab.h: Extend with a table that associates
3208 semantic types with their %destructor's and %printer's.
3209 (semantic_type_from_uniqstr, semantic_type_get,
3210 semantic_type_destructor_set, semantic_type_printer_set): New functions
3211 composing the public interface of that table.
3212 (symbol_destructor_get, symbol_destructor_location_get,
3213 symbol_printer_get, symbol_printer_location_get): If there's no
3214 per-symbol %destructor/%printer, look up the per-type before trying
3216 * tests/actions.at (Per-type %printer and %destructor): New test case.
3217 * tests/input.at (Default %printer and %destructor redeclared):
3218 Extend to check that multiple occurrences of %symbol-default in a
3219 single %destructor/%printer declaration is an error.
3220 (Per-type %printer and %destructor redeclared, Unused values with
3221 per-type %destructor): New test cases.
3223 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3225 Require default %destructor/%printer to be declared using
3226 %symbol-default instead of an empty symbol list, and start working on
3227 new per-type %destructor/%printer. Discussed at
3228 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
3229 * NEWS (2.3+): Add %symbol-default to example.
3230 * bison.texinfo (Freeing Discarded Symbols): Likewise.
3231 (Table of Symbols): Add entry for %symbol-default.
3232 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
3233 (generic_symlist, generic_symlist_item): New nonterminals for creating
3234 a list in which each item is a symbol, semantic type, or
3236 (grammar_declaration): Use generic_symlist in %destructor and %printer
3237 declarations instead of symbols.1 or an empty list.
3238 (symbol_declaration, precedence_declaration, symbols.1): Update actions
3239 for changes to symbol_list.
3240 * src/reader.c: Update for changes to symbol_list.
3241 * src/scan-code.l: Likewise.
3242 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
3243 * src/symlist.c, src/symlist.h: Extend such that a list node may
3244 represent a semantic type or a %symbol-default in addition to just an
3245 ordinary symbol. Add switched functions for setting %destructor's and
3247 * tests/actions.at, tests/input.at: Add %symbol-default to all default
3248 %destructor/%printer declarations.
3250 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
3252 Whether the default %destructor/%printer applies to a particular symbol
3253 isn't a question of whether the user *declares* that symbol (in %token,
3254 for example). It's a question of whether the user by any means
3255 *defines* the symbol at all (by simply using a char token, for
3256 example). $end is defined by Bison whereas any other token with token
3257 number 0 is defined by the user. The error token is always defined by
3258 Bison regardless of whether the user declares it with %token, but we
3259 may one day let the user define error as a nonterminal instead.
3260 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
3261 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
3262 the meaning of "user-defined".
3263 * tests/actions.at (Default %printer and %destructor for user-declared
3264 end token): Rename to...
3265 (Default %printer and %destructor for user-defined end token): ...
3268 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
3269 computation of whether to apply the default, don't maintain a list of
3270 every Bison-defined symbol. Instead, just check for a first character
3271 of '$', which a user symbol cannot have, and check for the error token.
3273 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
3275 Don't apply the default %destructor or %printer to the error token,
3276 $undefined, or $accept. This change fits the general rule that the
3277 default %destructor and %printer are only for user-declared symbols,
3278 and it solves several difficulties that are described in the new test
3280 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
3281 * tests/actions.at (Default %printer and %destructor are not for error
3282 or $undefined, Default %printer and %destructor are not for $accept):
3285 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
3287 Allow %start after the first rule.
3288 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
3289 when parsing the first rule.
3290 (check_and_convert_grammar): Search for it here after all grammar
3291 declarations have been parsed. Skip midrules, which have dummy LHS
3293 * src/symtab.c (symbol_is_dummy): New function.
3294 * src/symtab.h (symbol_is_dummy): Declare it.
3295 * tests/input.at (%start after first rule): New test.
3297 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3299 Redo some of the previous commit: add back the ability to use
3300 non-aliased/undeclared string literals since it might be useful to
3301 those declaring %token-table.
3302 * src/reader.c (check_and_convert_grammar): Undo changes in previous
3303 commit: don't worry about complaints from symbols_pack.
3304 * src/symtab.c (symbol_new, symbol_class_set,
3305 symbol_check_alias_consistency): Undo changes in previous commit: count
3306 each string literal as a new symbol and token, assign it a symbol
3307 number, and don't complain about non-aliased string literals.
3308 (symbols_pack): Since symbol_make_alias still does not decrement symbol
3309 and token counts but does still set aliased tokens to the same number,
3310 symbol_pack_processor now leaves empty slots in the symbols array.
3312 * tests/regression.at (Undeclared string literal): Remove test case
3313 added in previous commit since non-aliased string literals are allowed
3315 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
3316 remove unnecessary string literal declarations.
3317 * tests/sets.at (Firsts): Likewise.
3319 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3321 Don't allow an undeclared string literal, but allow a string literal to
3322 be used before its declaration.
3323 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
3324 symbols_pack complained.
3325 * src/symtab.c (symbol_new): Don't count a string literal as a new
3327 (symbol_class_set): Don't count a string literal as a new token, and
3328 don't assign it a symbol number since symbol_make_alias does that.
3329 (symbol_make_alias): It's not necessary to decrement the symbol and
3330 token counts anymore. Don't assume that an alias declaration occurs
3331 before any uses of the identifier or string, and thus don't assert that
3332 one of them has the highest symbol number so far.
3333 (symbol_check_alias_consistency): Complain if there's a string literal
3334 that wasn't declared as an alias.
3335 (symbols_pack): Bail if symbol_check_alias_consistency failed since
3336 symbol_pack asserts that every token has been assigned a symbol number
3337 although undeclared string literals have not.
3338 * tests/regression.at (String alias declared after use, Undeclared
3339 string literal): New test cases.
3340 (Characters Escapes, Web2c Actions): Declare string literals as
3342 * tests/sets.at (Firsts): Likewise.
3344 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
3346 In the grammar scanner, STRING_FINISH unclosed constructs and return
3347 them to the parser in order to improve error messages.
3348 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
3349 SC_BRACED_CODE, SC_PROLOGUE): Implement.
3350 * tests/input.at (Unclosed constructs): New test case.
3351 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
3354 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
3357 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
3359 Handle string aliases for character tokens correctly.
3360 * src/symtab.c (symbol_user_token_number_set): If the token has an
3361 alias, check and set its alias's user token number instead of its own,
3362 which is set to indicate the alias. Previously, every occurrence of
3363 the character token in the grammar overwrote that alias indicator with
3365 * tests/input.at (String aliases for character tokens): New test.
3367 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
3369 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
3371 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
3373 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
3374 to prevent failures when building on older platforms.
3375 Check for autopoint failure.
3376 Set XGETTEXT_OPTIONS to values that check for C format strings,
3377 so that translators are warned about them (this also helps
3378 prevent core dumps).
3380 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
3381 function, since it simplifies our code a bit.
3383 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
3384 rather than -W, so we don't get bogus warnings about sign comparisons.
3385 Add -Wpointer-arith, since that warning is useful (it reports code
3386 that does not conform to C89 and that some compilers reject).
3387 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
3388 since it's no longer needed.
3390 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
3392 Clean up scanners a bit.
3393 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
3394 definitions so gcc won't warn when obstack_for_string is unused.
3395 * src/scan-code.l: config.h and system.h are already #include'd by
3396 scan-code-c.c, so get rid of them here.
3397 * src/scan-gram.l: Likewise.
3398 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
3399 definitions rather than duplicating the rest of it.
3400 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
3402 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
3404 Suppress signed/unsigned comparison warnings for yycheck.
3405 * data/c.m4 (b4_safest_int_type): New macro.
3406 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
3407 a signed int type, cast it to b4_safest_int_type first.
3408 * data/yacc.c: Likewise.
3409 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
3412 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
3414 * doc/bison.texinfo: Fix some typos.
3416 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
3418 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
3419 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
3421 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
3422 the latest gnulib does this a different way.
3423 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
3424 translation was patched, so stop omitting it.
3426 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3428 Enable declaration of default %printer/%destructor. Make the parser
3429 use these for all user-declared grammar symbols for which the user does
3430 not declare a specific %printer/%destructor. Thus, the parser uses it
3431 for token 0 if the user declares it but not if Bison generates it as
3432 $end. Discussed starting at
3433 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
3434 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
3436 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
3437 * NEWS (2.3+): Mention.
3438 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
3439 declare a %destructor for a mid-rule's semantic value. It's just
3440 impossible to declare one specific to it.
3441 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
3442 code. Describe default %destructor form.
3443 * src/parse-gram.y (grammar_declaration): Parse default
3444 %printer/%destructor declarations.
3445 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
3446 and symbol_destructor_location_get rather than accessing the destructor
3447 and destructor_location members of struct symbol.
3448 (symbol_printers_output): Likewise but for %printer's.
3449 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
3451 * src/symtab.c (default_destructor, default_destructor_location,
3452 default_printer, default_printer_location): New static global
3453 variables to record the default %destructor and %printer.
3454 (symbol_destructor_get, symbol_destructor_location_get,
3455 symbol_printer_get, symbol_printer_location_get): New functions to
3456 compute the appropriate %destructor and %printer for a symbol.
3457 (default_destructor_set, default_printer_set): New functions to set the
3458 default %destructor and %printer.
3459 * src/symtab.h: Prototype all those new functions.
3460 * tests/actions.at (Default %printer and %destructor): New test to
3461 check that the right %printer and %destructor are called, that they're
3462 not called for $end, and that $$ and @$ work correctly.
3463 (Default %printer and %destructor for user-declared end token): New
3464 test to check that the default %printer and %destructor are called for
3465 a user-declared end token.
3466 * tests/input.at (Default %printer and %destructor redeclared, Unused
3467 values with default %destructor): New tests to check related grammar
3468 warnings and errors.
3470 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3472 Clean up handling of %destructor for the end token (token 0).
3473 Discussed starting at
3474 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
3476 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
3478 Make the skeletons consistent in how they pop the end token and invoke
3480 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
3481 state, which has token number 0, since this would invoke the
3482 %destructor for the end token.
3483 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
3484 until after shifting the end token, or else it won't be popped.
3485 * data/yacc.c (yyparse): Likewise.
3487 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
3488 it's the end token. Upon termination, destroy an unshifted lookahead
3489 even when it's the end token.
3490 * data/lalr1.cc (yy::parser::parse): Likewise.
3491 * data/yacc.c (yyparse): Likewise.
3493 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
3494 value warnings for the end token when the user gives the end token a
3497 * tests/actions.at (Printers and Destructors): Test all the above.
3499 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
3501 Update to latest gnulib and gettext versions.
3502 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
3504 (gnulib_files): Add m4/warning.m4. Don't worry about files
3505 overwritten by autopoint.
3506 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
3507 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
3509 Don't use autoreconf; instead, invoke autopoint etc. by hand,
3510 so that we can remove the intl files at a better time.
3511 (intl_files_to_remove): Remove aclocal.m4, since it gets
3512 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
3513 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
3514 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
3515 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
3516 Remove datarootdir hack; no longer needed.
3517 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
3518 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
3519 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
3521 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
3522 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
3524 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3526 * bootstrap: Adjust to today's change to gnulib-tool by invoking
3527 it with --assume-autoconf='latest-stable'.
3529 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
3531 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
3532 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
3534 * src/muscle_tab.h (muscle_grow): Replace the header comments with
3535 those from muscle_tab.c since the old ones are misleading.
3537 2006-07-13 Akim Demaille <akim@epita.fr>
3539 Support %define "KEY" {VALUE}.
3540 * src/scan-code.h, src/scan-code.l (translate_action)
3541 (translate_rule_action, translate_symbol_action, translate_code):
3542 Return char *, not const char *.
3543 * src/parse-gram.y (declaration): Rename as...
3544 (prologue_declaration): this.
3545 (string_content): Remove this nonterminal, use STRING.
3546 (braceless, content, content.opt): New nonterminal.
3548 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
3550 * src/scan-gram.l (getargs.h): Don't include it.
3552 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
3554 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
3555 rather than a for-loop that declares a local bool variable. This
3556 should work around a compatibility problem with a Cray x1e C++
3557 compiler reported by Hung Nguyen in
3558 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
3559 The for-loop was introduced in the 2004-11-17 change but I don't
3560 know why it was needed.
3562 2006-07-12 Akim Demaille <akim@epita.fr>
3564 * data/c.m4: Comment changes.
3566 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
3568 * src/complain.c (error_message, ERROR_MESSAGE): New.
3570 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
3571 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
3573 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
3575 * NEWS: Instead of %union, you can define and use your own union type
3576 YYSTYPE if your grammar contains at least one <type> tag.
3577 Your YYSTYPE need not be a macro; it can be a typedef.
3578 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
3579 (Union Decl, Decl Summary): Document this.
3580 * data/glr.c (YYSTYPE): Implement this.
3581 * data/glr.cc (YYSTYPE): Likewise.
3582 * data/lalr1.cc (YYSTYPE): Likewise.
3583 * data/yacc.c (YYSTYPE): Likewise.
3584 * src/output.c (prepare): Output tag_seen_flag.
3585 * src/parse-gram.y (declaration, grammar_declaration):
3586 Use 'union_seen' rather than 'typed' to determine whether
3587 %union has been seen, since grammars can now be typed without
3589 (symbol_declaration, type.opt, symbol_def):
3590 Keep track of whether a tag has been seen.
3591 * src/reader.c (union_seen, tag_seen): New vars.
3593 * src/reader.h (union_seen, tag_seen, typed): Likewise.
3594 * src/scan-code.l (untyped_var_seen): New variable.
3595 (handle_action_dollar): Adjust to above changes.
3596 (handle_action_dollar, handle_action_at):
3597 Improve overflow checking for outlandish numbers.
3598 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
3599 avoid new diagnostics generated by above changes.
3600 * tests/regression.at (YYSTYPE typedef): Add test to check
3601 for type tags without %union.
3603 * src/symlist.c (symbol_list_length): Return int, not unsigned
3604 int, since callers expect int. This may need to get revisited
3605 once we have proper integer overflow checking.
3607 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
3608 object is now static.
3610 * src/getargs.c (flags_argmatch): Return void, not int,
3611 to pacify ./configure --enable-gcc-warnings.
3613 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
3614 since last_string is already defined to FLEX_PREFIX (last_string).
3616 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
3618 Implement --warnings/-W.
3619 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
3621 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
3623 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
3624 (warnings_args, warnings_types): New.
3625 (getargs, short_options, long_options): Accept -W/--warnings.
3626 Sort the options by alphabetical order, upper case letter right
3627 before its lower case.
3629 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3631 Change %merge result type clash warnings to errors. Discussed at
3632 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
3633 * src/reader.c (record_merge_function_type): Use complain_at.
3634 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3635 declared later): Update test case results.
3637 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
3639 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
3640 to be in alphabetical order.
3641 (trace_args): Spelling fixes.
3643 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
3645 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
3646 so they don't collide with user-defined macros.
3647 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
3648 this was never guaranteed, and now that we're using gnulib stdint,
3649 which defines int_fast16_t to long int, the problem is exposed.
3651 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
3653 * data/c.m4 (b4_basename): Simplify a bit, since we don't
3654 need the full POSIX semantics (and weren't implementing them
3657 Adjust to Autoconf 2.60 and today's gnulib.
3658 * bootstrap (gnulib_modules): Add stdint.
3659 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
3660 no longer copies it.
3661 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
3662 since stdint needs the former and wcwidth (which is now required
3663 by mbswidth) needs the latter.
3664 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
3665 work around a compatibility glitch between gettext 0.14.6 and
3667 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
3668 Do not check for uintptr_t, since new stdint module does the right
3670 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
3671 Add stdint.h, stdint_.h, wcwidth.h.
3672 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
3673 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
3674 stdint.m4, wchar_t.m4, wcwidth.m4.
3675 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
3676 usual order for ../lib/*.h files.
3677 (file_name_split): Use last_component, not base_name, to adjust
3679 * src/parse-gram.h: Include <strverscmp.h> in the usual order
3680 for ../lib/*.h files.
3681 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
3682 Define unconditionally, since we now assume the stdint module.
3683 * src/scan-skel.l: Include <dirname.h>.
3684 (BASE_QPUTS): Use last_component, not base_name.
3685 * src/system.h: Include <unlocked-io.h> in the usual order
3686 for ../lib/*.h files. Include <stdint.h> unconditionally,
3687 since we now use the stdint module.
3688 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
3689 HAVE_UINTPTR_T, since we now use the stdint module.
3690 (base_name): Remove decl, since files now include <dirname.h>
3693 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
3695 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
3697 * data/yacc.c, data/glr.c, data/location.cc: Use them.
3698 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
3700 * tests/calc.at: Adjust.
3702 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
3704 * data/c.m4 (b4_basename): New.
3705 (b4_syncline): Also output the location of its invocation (from
3707 (b4_user_action, b4_define_user_action, b4_user_actions)
3708 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
3709 (b4_user_stype): New.
3710 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
3712 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
3714 In the grammar file, the first column is 1 not 0 on the first line as
3715 on every other line.
3716 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
3717 * tests/input.at (Torturing the Scanner): Update output.
3719 * src/scan-gram.l (scanner_cursor): Declare it static.
3721 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
3723 In warnings, say "previous declaration" rather than "first
3725 * src/symtab.c (redeclaration): Do that here.
3726 * src/reader.c (record_merge_function_type): In the case of a result
3727 type clash, report the previous declaration rather than the very first
3728 one in the grammar file.
3729 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3730 declared later): Add a third declaration to check this behavior.
3731 * tests/input.at (Incompatible Aliases): Update output.
3733 2006-06-27 Akim Demaille <akim@epita.fr>
3735 * doc/Doxyfile.in: New.
3736 * doc/Makefile.am: Use it.
3737 * src/lalr.h, src/symtab.h: Initial doxygenation.
3739 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3741 Don't miss %merge result type warnings just because the LHS types are
3742 declared after the %merge. This continues the effort of the previous
3744 * src/reader.c (get_merge_function): Don't set the merger type yet.
3745 (record_merge_function_type): New function for setting the merger type
3746 and checking for clashes.
3747 (grammar_current_rule_merge_set): Set the location of the %merge for
3749 (packgram): Invoke record_merge_function_type for each rule now that
3750 all symbol type declarations have been parsed.
3751 * src/reader.h (merger_list.type_declaration_location): New member
3752 storing the location of the first %merge from which the type for this
3753 merging function was derived.
3754 * src/symlist.h (symbol_list.merger_declaration_location): New member
3755 storing the location of a rule's %merge, if any.
3756 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3757 declared later): New test to catch the error fixed by the above patch.
3759 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3761 Get action warnings (grammar_rule_check) right even when symbol
3762 declarations appear after the rules. Discussed at
3763 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
3765 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
3766 Don't mistake the type of $$ in a midrule to be that of its parent
3768 * src/reader.c (grammar_current_rule_end): Don't invoke
3769 grammar_rule_check yet since not all symbol declarations may have been
3771 (grammar_midrule_action): Likewise.
3772 Don't record whether the midrule's $$ has been used yet since actions
3773 haven't been translated yet.
3774 Record the midrule's parent rule and its RHS index within the parent
3776 (grammar_current_rule_action_append): Don't translate the action yet
3777 since not all symbol declarations may have been parsed yet and, thus,
3778 warnings about types for $$, $n, @$, and @n can't be reported yet.
3779 (packgram): Translate the action and invoke grammar_rule_check now that
3780 all symbol declarations have been parsed.
3781 * src/scan-code.l (handle_action_dollar): Now that this is invoked
3782 after parsing the entire grammar file, the symbol list here in the case
3783 of a midrule is actually the midrule's empty RHS, so reference its
3784 parent rule's RHS where necessary.
3785 On the other hand, now that you can already know it's a midrule, you
3786 aren't forced to think $$ has the same type as its parent rule's $$.
3787 (handle_action_at): In the case of a midrule, reference the parent rule
3789 * src/symlist.c (symbol_list_new): Initialize new midrule-related
3791 (symbol_list_length): Now that this is invoked after all rules have
3792 been parsed, a NULL symbol (rather than a NULL symbol list node)
3793 terminates a rule. symbol_list_print already does this correctly.
3794 * src/symlist.h (symbol_list.midrule_parent_rule,
3795 symbol_list.midrule_parent_rhs_index): New members so that midrules can
3796 remember their relationships with their parents.
3797 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
3798 fixed by the above patch.
3799 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
3801 (Unused values): ... this old test case and...
3802 (Unused values before symbol declarations): ... this new test case.
3803 This one is the same as `Unused values' except that all symbol
3804 declarations appear after the rules in order to catch the rest of the
3805 errors fixed by the above patch.
3807 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3810 * src/reader.c (current_rule): Declare it static since it's no longer
3811 used outside this file.
3812 (grammar_current_rule_action_append): Remove redundant arguments from
3813 translate_rule_action invocation.
3814 * src/reader.h (current_rule): Remove this unused extern.
3815 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
3816 * src/scan-code.l (translate_rule_action): Likewise.
3818 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
3820 Clean up yesterday's patch.
3821 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
3823 * src/reader.c (grammar_current_rule_action_append): ... here for
3824 consistency with grammar_current_rule_symbol_append.
3825 * tests/regression.at (Braced code in declaration in rules section):
3826 Make yyerror and yylex static as usual.
3828 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
3830 Fix bug that mistakes braced code in a declaration in the rules section
3831 to be a rule action. Mentioned at
3832 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
3833 * src/scan-gram.l: Move midrule action detection from the start of the
3834 scanning of any braced code to...
3835 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
3836 action. For readability, use $2 and @2 rather than the equivalent
3838 * tests/regression.at (Braced code in declaration in rules section):
3839 New test to catch the error fixed by the above patch.
3841 Work on code readability some.
3842 * src/scan-code.l (current_rule): Get rid of this misleading and
3843 redundant declaration: it's actually extern'ed in reader.h.
3844 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
3845 translate_action): Add a rule argument and use it instead of the global
3847 (translate_rule_action): This already receives current_rule through an
3848 argument, so pass it on to translate_action instead of assigning
3849 current_rule to current_rule.
3850 (translate_symbol_action, translate_code): Pass rule = NULL to
3853 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
3855 Rename %before-definitions to %start-header and %after-definitions to
3856 %end-header. Don't use these declarations to separate pre-prologue
3857 blocks from post-prologue blocks. Add new order-independent
3858 declarations %before-header and %after-header as alternatives to the
3859 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
3860 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
3861 * NEWS (2.3+): Update for these changes.
3862 * data/glr.c (b4_before_definitions): Update to...
3863 (b4_start_header): ... this.
3864 (b4_after_definitions): Update to...
3865 (b4_end_header): ... this.
3866 * data/glr.cc: Likewise.
3867 * data/lalr1.cc: Likewise.
3868 * data/yacc.c: Likewise.
3869 * doc/bison.texinfo (The prologue): Update names, and replace remaining
3870 prologue blocks with %*-header declarations.
3871 (Calc++ Parser): Likewise.
3872 (Decl Summary): Update names.
3873 (Table of Symbols): Update description.
3874 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
3875 (PERCENT_END_HEADER): ... this.
3876 (PERCENT_BEFORE_DEFINITIONS): Update to...
3877 (PERCENT_START_HEADER): ... this.
3878 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
3879 (declaration): Update token names and m4 macro names.
3880 When parsing %end-header and %start-header, invoke translate_code
3881 before muscle_code_grow, and no longer set global booleans to remember
3882 whether these declarations have been seen.
3883 Parse new %after-header and %before-header.
3884 * src/reader.c (before_definitions, after_definitions): Remove.
3885 (prologue_augment): Accept a new bool argument to specify whether to
3886 augment the pre-prologue or post-prologue.
3887 * src/reader.h (before_definitions, after_definitions): Remove these
3889 (prologue_augment): Add new bool argument.
3890 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
3891 (PERCENT_END_HEADER): ... this.
3892 (PERCENT_BEFORE_DEFINITIONS): Update to...
3893 (PERCENT_START_HEADER): ... this.
3894 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
3895 * tests/actions.at (Printers and Destructors): Update names.
3897 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
3899 Add comparison operators for C++ location classes. Discussed at
3900 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
3901 * data/c++.m4 (b4_define_location_comparison): New boolean %define
3902 declaration indicating whether filename_type has an operator==. If
3903 filename_type is `std::string', it defaults to `1', `0' otherwise.
3904 * data/location.cc: Iff b4_define_location_comparison is `1', add
3905 operator== and operator!= for class position and for class location.
3908 * src/scan-action.l: Remove unused file.
3909 * src/symtab.c (symbol_printer_set): Use printer_location not
3910 destructor_location.
3911 * src/symtab.h (struct symbol): Replace incorrect source comment for
3913 * tests/input.at (Incompatible Aliases): Update output with correct
3916 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
3918 Don't put the pre-prologue in the header file. For the yacc.c code
3919 file and the glr.c header and code files, move the pre-prologue before
3920 the token definitions. Add new %before-definitions and
3921 %after-definitions to declare code that will go in both the header file
3922 and code file. Discussed at
3923 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
3924 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
3926 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
3927 * NEWS (2.3+): Describe these changes.
3928 * data/glr.c (b4_pre_prologue): Move from within to before...
3929 (b4_shared_declarations): ... this.
3930 Add new b4_before_definitions before b4_token_enums.
3931 Add new b4_after_definitions at the end.
3932 * data/glr.cc (b4_pre_prologue): Replace with...
3933 (b4_before_definitions): ... this in the header file.
3934 (b4_after_definitions): New near the end of the header file.
3935 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
3936 code file right before including the header file.
3937 (b4_before_definitions): New in the previous position of
3938 b4_pre_prologue in the header file.
3939 (b4_after_definitions): New near the end of the header file.
3940 * data/yacc.c: Clean up some m4 quoting especially in the header file.
3941 (b4_token_enums_defines): In the code file, move to right before
3942 YYSTYPE for consistency with the header file.
3943 (b4_before_definitions): New right before b4_token_enums_defines in
3944 both the header and code file.
3945 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
3946 header and code file.
3947 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
3948 of prologues for %union dependencies.
3949 (Decl Summary): In %defines description, mention the effect of
3950 %before-definitions and %after-definitions on the header file.
3951 (Calc++ Parser): Forward declare driver in a %before-definitions rather
3952 than in the pre-prologue so that make check succeeds.
3953 (Table of Symbols): Add entries for %before-definitions and
3955 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
3956 %before-definitions.
3957 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
3958 (declaration): Parse those declarations and append to
3959 b4_before_definitions and b4_after_definitions, respectively.
3960 * src/reader.c (before_definitions, after_definitions): New bools to
3961 track whether those declarations have been seen.
3962 (prologue_augment): Add to the post-prologue if %union,
3963 %before-definitions, or %after-definitions has been seen.
3964 * src/reader.h (before_definitions, after_definitions): New extern's.
3965 * src/scan-gram.l: Scan the new declarations.
3966 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
3967 prologue block in a %before-definitions or a %after-definitions based
3968 on whether the %union is declared.
3969 * tests/regression.at (Early token definitions with --yacc, Early token
3970 definitions without --yacc): Move tests for token definitions into the
3971 post-prologue since token names are no longer defined in the

3976 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
3977 (symbol_get): Use it.

3980 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
3982 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
3983 build succeeds when configured with --enable-gcc-warnings.
3985 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3987 * src/parse-gram.y (char_name): New function.
3988 (CHAR, STRING, string_content): For %printer, properly escape.
3989 (ID): Prefer fputs to fprintf.
3990 (id): Reindent to be consistent with other rules.
3991 Properly quote char.
3993 The Translation Project changed its way of publishing translations
3994 to maintainers. I haven't received any responses to my request
3995 for supporting the old way, or for documenting the new way. I
3996 have modified 'bootstrap' to use screen scraping
3997 (in this case, HTML scraping). This is unreliable and inelegant,
3998 but I don't see any better way. Yuck.
3999 * bootstrap (TP_URL, WGET_COMMAND): New vars.
4000 (get_translations): New function, which uses HTML scraping to
4001 deduce locations of latest translations.
4002 Use this function to grab both bison and bison-runtime .po files.
4003 Don't bother priming the pump for the runtime-po domain any more,
4004 as it's now translated better than bison is.
4006 2006-06-19 Akim Demaille <akim@epita.fr>
4008 * src/scan-gram.l: No longer "parse" things after `%union' until
4009 `{'. Rather, return a single "%union" token.
4010 No longer make symbols: return strings, and leave the conversion
4011 to symbols to the parser.
4012 (SC_PRE_CODE, token_type): Remove.
4013 * src/parse-gram.y (%union): New field `character'.
4016 (ID, ID_COLON): Now that the scanner no longer makes them
4017 identifiers, adjust all uses to invoke symbol_get.
4018 (id_colon): New, wraps the conversion from string to symbol.
4019 (%union): Accept a possible union_name.
4020 (symbol): Now can be a char.
4021 * data/c.m4 (b4_union_name): Leave a default value.
4022 * data/glr.c, data/yacc.c: Use it.
4024 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
4026 For associating token numbers with token names for "yacc.c", don't use
4027 #define statements unless `--yacc' is specified; always use enum
4028 yytokentype. Most important discussions start at:
4029 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
4030 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
4032 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
4033 * NEWS (2.3+): Mention.
4034 * data/c.m4 (b4_yacc_if): New.
4035 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
4037 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
4038 on token name definitions.
4039 * src/getargs.c (usage): Capitalize `Yacc' in English.
4040 * src/output.c (prepare): Define b4_yacc_flag.
4041 * tests/regression.at (Early token definitions): Test that tokens names
4042 are defined before the pre-prologue not just before the post-prologue.
4043 Remove this test case and copy to...
4044 (Early token definitions with --yacc): ... this to test #define's.
4045 (Early token definitions without --yacc): ... and this to test enums.
4047 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
4049 * NEWS: Reword the post-2.3 change to not be so optimistic about
4050 removing the old "look-ahead" spelling.
4051 Update previous look-ahead/lookahead change reports.
4052 * REFERENCES: look-ahead -> lookahead (since that's
4053 what he actually wrote).
4054 * doc/refcard.tex: look ahead -> lookahead,
4055 look-ahead -> lookahead
4057 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
4059 For consistency, use `lookahead' instead of `look-ahead' or
4060 `look_ahead'. Discussed starting at

4093 * src/print.c: Update English in comments.
4094 (lookahead_set): Rename from look_ahead_set.

4130 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
4132 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
4134 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4136 * TODO: Add request from Nelson H. F. Beebe to be able to install
4137 Bison without installing the yacc script.
4139 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
4141 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
4142 and yytext if they're already #define'd.
4143 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
4144 * src/scan-code-c.c: ... here.
4145 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
4148 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
4150 Get Bison to build again when configured with --enable-gcc-warnings.
4151 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
4153 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
4154 loc argument as it shadows a global.
4155 * src/scan-gram.l: Remove stray comma that prevents boundary_set
4158 * src/.cvsignore: Add scan-code.c.
4160 2006-06-07 Akim Demaille <akim@epita.fr>
4162 * src/scan-gram.l: Move the "add a trailing ; to actions" code
4164 * src/scan-code.l: here.
4165 * tests/input.at (Torturing the Scanner): Fix another location
4168 2006-06-07 Akim Demaille <akim@epita.fr>
4170 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
4172 2006-06-06 Akim Demaille <akim@epita.fr>
4174 Extract the parsing of user actions from the grammar scanner.
4175 As a consequence, the relation between the grammar scanner and
4176 parser is much simpler. We can also split "composite tokens" back
4178 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
4179 * src/scan-gram.l (add_column_width, adjust_location): Move to and
4181 * src/location.h, src/location.c (add_column_width)
4182 (location_compute): these.
4183 Fix the column count: the initial column is 0.
4184 (location_print): Be robust to ending column being 0.
4185 * src/location.h (boundary_set): New.
4186 * src/main.c: Adjust to scanner_free being renamed as
4188 * src/output.c: Include scan-code.h.
4189 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
4191 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
4192 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
4193 which is now, again, a separate token.
4194 Adjust all dependencies.
4195 Whereever actions with $ and @ are used, use translate_code.
4196 (action): Remove this nonterminal which is now useless.
4197 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
4198 (grammar_current_rule_action_append): Use translate_code.
4199 (packgram): Bound check ruleno, itemno, and rule_length.

4201 (last_string, last_braced_code_loc, max_left_semantic_context)
4202 (scanner_initialize, scanner_free, scanner_last_string_free)
4203 (gram_out, gram_lineno, YY_DECL_): Move to...
4204 * src/scan-gram.h: this new file.
4205 (YY_DECL): Rename as...
4207 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
4208 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
4209 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
4210 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
4211 Move these declarations, and...
4212 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
4214 * src/flex-scanner.h: this new file.
4215 * src/scan-gram.l (rule_length, rule_length_overflow)
4216 (increment_rule_length): Remove.
4217 (last_braced_code_loc): Rename as...
4218 (gram_last_braced_code_loc): this.
4219 Adjust to the changes of the parser.
4220 Move all the handling of $ and @ into...
4221 * src/scan-code.l: here.
4222 * src/scan-gram.l (handle_dollar, handle_at): Remove.
4223 (handle_action_dollar, handle_action_at): Move to...
4224 * src/scan-code.l: here.

4235 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4237 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4238 Use Akim's wording from
4239 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
4241 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4243 Between Bison releases, manually append `+' to the previous Bison
4244 release number, and use that as a signal to automatically print the
4245 ChangeLog's CVS Id keyword from --version. Discussed starting at
4246 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
4247 * ChangeLog: Add Id header.
4248 * configure.ac (AC_INIT): Append `+' to `2.3'.
4249 * src/.cvsignore: Add revision.c.
4250 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
4251 (BUILT_SOURCES): Add revision.c.
4252 (revision.c): New target rule. This file defines a new global variable
4253 named revision. It initializes it with either the Id from ChangeLog
4254 or, if VERSION doesn't contain `+', with the empty string.
4255 * src/getargs.c (version): Print the value of revision.
4256 * src/revision.h: Extern revision.
4258 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4260 * NEWS: Version 2.3.
4261 * configure.ac (AC_INIT): Likewise.
4263 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4265 * data/glr.c (YYRECOVERING): Define to be a function-like macro
4266 with no arguments, not as an object-like macro. This is for
4267 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
4268 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
4269 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
4272 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
4274 * src/getargs.c (usage): Back out yesterday's modification of the
4275 --help output so that we don't have to wait for translation before
4278 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4280 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
4281 Problem reported by Akim Demaille.
4283 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4285 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4287 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4289 * data/yacc.c (yy_reduce_print): Omit trailing white space in
4290 generated source code. Problem reported by Frans Englich in
4291 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
4293 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
4295 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
4296 shell, not within 'make', so that 'make' by an ordinary builder
4297 (using GNU make) does not worry about configuring gzip. This also
4298 works around a bug reported independently by Keith Thompson and by
4299 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
4300 stderr rather than stdout, messing up the build logs.
4302 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4304 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
4305 to make sure that YYID will never be unused. This fixes a 'make
4306 maintainer-check' failure caused by the recent changes to the 'Trivial
4307 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
4309 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
4311 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4313 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
4314 state before an empty RHS is always resolved here. Only the location
4315 of that state is guaranteed to be resolved, and that's enough. This
4316 fixes the remaining bug reported by Derek M. Jones in
4317 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4318 * tests/glr-regression.at (Uninitialized location when reporting
4319 ambiguity): Test the above case.
4320 Also, the embedded comments in this test case claim it checks the case
4321 of an empty RHS that has inherited the initial location. However, the
4322 corresponding LHS was already resolved, so yyresolveLocations didn't
4323 actually have reason to modify it. Fix this by forcing
4324 nondeterministic operation at the beginning of the parse.
4326 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4328 * data/c.m4 (b4_yy_symbol_print_generate):
4329 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
4330 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
4331 of the bugs reported today by Derek M Jones in
4332 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4333 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
4334 defined to be a type name without parens or brackets.
4335 (Location Type): Similarly for YYLTYPE.
4336 * tests/regression.at (Trivial grammars): Put in a test for this
4337 bug that will be caught by 'make maintainer-check' (though not,
4338 alas, by 'make check' unless your compiler is picky).
4340 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4342 * NEWS: Version 2.2.
4343 * configure.ac (AC_INIT): Likewise.
4345 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
4347 * data/glr.c (yyreportTree): Make room in yystates for the state
4348 preceding the RHS. This fixes the segmentation fault reported by Derek
4350 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
4351 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
4352 to the user. Reported for yyreportTree by Derek M. Jones later in the
4354 * THANKS: Add Derek M. Jones.
4355 Update my email address.
4356 Fix typo in Steve Murphy's name.
4358 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4360 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
4361 checking against YYLAST that caused the parser to miss a potential
4362 alternative in its diagnostic.
4363 Problem reported by Maria Jose Moron Fernandez in
4364 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
4365 * data/lalr1.cc (yysyntax_error_): Likewise.
4366 * data/yacc.c (yysyntax_error): Likewise.
4367 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
4368 tokens, in case we run into an older C compiler.
4369 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
4370 Use them to check for the off-by-one error fixed above.
4372 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
4373 YYSIZE_T, not size_t.
4374 * tests/regression.at (Trivial grammars): New test, to catch
4375 the error fixed by the above patch.
4377 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4379 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
4381 Reported by Steve Murphy.
4383 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4385 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
4386 * data/glr.cc: b4_location_flag is now b4_locations_flag.
4388 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4390 Implement --trace=m4.
4391 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
4392 * src/output.c (output_skeleton): When set, pass -dV to m4.
4394 Factor the handling of flags in m4.
4395 * src/output.c (prepare): Rename the muscle names debug, defines,
4396 error_verbose to debug_flag, defines_flag, error_verbose_flag.
4397 * data/c.m4: Adjust.
4398 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
4399 Use b4_define_flag_if to define other b4_FLAG_if macros.
4400 (b4_location_if): As a consequence, rename as...
4401 (b4_locations_if): this, for consistency.
4402 Adjust all the skeletons.
4404 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4406 * etc/bench.pm: Shorten bench names.
4408 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4410 * src/output.h, src/output.c (error_verbose): Move to...
4411 * src/getargs.h, src/getargs.c: here.
4413 Adjust dependencies.
4415 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4417 * data/c.m4 (b4_copyright): Put the special exception for Bison
4418 skeletons here, so we don't have to put it in each skeleton. All
4419 uses changed. Suggested by Akim Demaille. Also, wrap the
4420 copyright notice, in case it is longer than 80 columns. Replace
4421 comma by newline after title.
4423 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4425 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
4426 incompatibility, not a bug. Mention that it wasn't fixed as of
4429 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4431 * examples/extexi: Enforce the precedence of concatenation over
4433 Reported by Tommy Nordgren.
4435 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4437 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
4438 with the member "token".
4439 Reported by Martin Nylin.
4441 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
4443 * data/glr.c: Switch to Bison 2.2 special-exception language in
4444 the copyright notice. Use more-regular format for titles and
4446 * data/glr.cc: Likewise.

4454 * data/glr.cc: Remove dead code.
4456 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4458 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
4459 that variable and the line breaks the bootstrap. Problem reported
4460 by Juan M. Guerrero.
4462 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

4480 Problem reported by Bob Rossi.
4482 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
4484 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
4485 and didn't really work.
4486 For the index, use @ifnotinfo, not @iftex.
4487 Minor cleanups of spacing and terminology.
4489 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4491 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
4492 of AT_NAME_PREFIX when %name-prefix is not used.
4494 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4496 Apply --prefix to C++ skeletons too: they change the namespace.
4497 The test suite already exercize these cases.
4498 * data/c++.m4 (b4_namespace): New.
4499 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
4500 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
4501 * data/yacc.c, data/glr.c: Remove a useless `[]'.
4502 * doc/bison.texinfo: Document it.
4503 (Option Cross Key): Use @multitable in all formats. It looks
4504 nicer, even in TeX outputs.
4505 (Rules): Use the same code whatever the output type is.
4506 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
4507 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.

4529 Fix two nits reported by twlevo, plus one more that I discovered.
4531 * src/assoc.h (assoc_to_string): Give a name to the arg, as
4532 this is the usual Bison style.
4533 * src/location.h (location_print): Likewise.
4535 * src/reader.h (token_name): Likewise.
4537 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
4539 Fix some nits reported by twlevo.
4540 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
4541 and "POSIX". Use more-modern syntax for URLs. Mention C++
4542 and ask for Java. Don't hardwire OS version numbers. Add
4544 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
4545 * src/conflicts.c (solved_conflicts_obstack): Now static.
4547 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
4549 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
4550 page. Say "you can use it" not "you may use it" as on the web page;
4551 we're describing capabilities not granting permission.
4553 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
4555 * data/glr.c (yyresolveLocations): Rename local variables to avoid
4556 shadowing warnings. Use usual patter for iterating through RHS.
4557 * tests/glr-regression.at
4558 (Uninitialized location when reporting ambiguity):
4559 Modify yylex so that it uses its argument, rather than trying
4560 to rely on ARGSUSED (which doesn't work for gcc with warnings).
4561 const char -> char const.
4563 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
4564 Don't use tabs inside commands; it messes up 'ps'.
4565 Problem reported by twlevo.
4567 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
4569 * tests/glr-regression.at (Uninitialized location when reporting
4570 ambiguity): New test case.
4571 * data/glr.c (yyresolveLocations): New function, which uses
4573 (yyresolveValue): Invoke yyresolveLocations before reporting an
4575 * doc/bison.texinfo (Default Action for Locations): Note
4576 YYLLOC_DEFAULT's usage for ambiguity locations.
4577 (GLR Semantic Actions): Cross-reference those notes.
4579 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
4581 * tests/glr-regression.at (Leaked semantic values when reporting
4582 ambiguity): Remove unnecessary union and type declarations.
4583 (Leaked lookahead after nondeterministic parse syntax error): New test
4585 * data/glr.c (yyparse): Check for zero stacks remaining before
4586 attempting to shift the lookahead so that you don't lose it.
4588 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
4590 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
4591 * tests/glr-regression.at (Leaked semantic values when reporting
4592 ambiguity): New test case.
4593 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
4594 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
4595 now unnecessary yystackp parameter.
4596 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
4597 destructors can be called.
4599 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
4600 in existing testcases.
4602 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
4604 Don't leak semantic values for parent RHS when a user action cuts the
4605 parser, and clean up related code a bit.
4606 * tests/glr-regression.at (Leaked merged semantic value if user action
4607 cuts parse): Rename to...
4608 (Leaked semantic values if user action cuts parse): ... this. Add check
4609 for leaked parent RHS values.
4610 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
4611 between an unresolved state (non-empty chain of semantic options) and
4612 an incomplete one (signaled by an empty chain).
4613 (yyresolveStates): Document the interface. Move all manipulation of a
4614 successfully or unsuccessfully resolved yyGLRState to...
4615 (yyresolveValue): ... here so that yyresolveValue always leaves a
4616 yyGLRState with consistent data and thus is easier to understand.
4617 Remove the yyvalp and yylocp parameters since they are always just
4618 taken from the yys parameter. When reporting a discarded merged value
4619 in debugging output, note that it is incompletely merged. Document the
4621 (yyresolveAction): If resolving any of the RHS states fails, destroy
4622 them all rather than leaking them. Thus, as long as user actions are
4623 written to clean up the RHS correctly, yyresolveAction always cleans up
4624 the RHS of a semantic option. Document the interface.
4626 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
4628 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
4629 led to a segmentation fault in GNU Pascal. Problem reported
4632 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
4634 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
4635 mid-rule action inside a nonterminal symbol in order to declare a
4636 destructor for its semantic value.
4638 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>

4642 __cplusplus && ! defined _STDLIB_H && !
4643 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
4644 defined free))]: Include <stdlib.h> rather than rolling our own
4645 declarations of malloc and free, to avoid problems with
4646 incompatible declarations (using 'throw') C++'s stdlib.h. This
4647 should fix Debian bug 340012

4660 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
4661 since C99 requires this.
4663 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
4665 * m4/c-working.m4: New file.

4674 More portability fixes for problems summarized by Nelson H. F. Beebe.

4677 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
4678 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
4679 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

4685 More portability fixes for problems summarized by Nelson H. F. Beebe.
4687 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
4688 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
4690 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
4691 nodist_PROGRAMS, since we don't need to actually compile the
4692 example if we're just doing a plain 'make'. This avoids bothering
4693 the installer unnecessarily about problems due to weird C++

4698 More portability fixes for problems summarized by Nelson H. F. Beebe.
4700 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
4701 than #include "...", and compile with -I'.'. The old method was
4702 not portable, according to Posix and the C standard, and it does
4703 not work with Sun C 5.7, where previous #line directives affect
4704 the working directory used in later #include "..." directives.

4717 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
4719 Work around portability problems summarized by Nelson H. F. Beebe in

4723 that '#include <string>' works.
4725 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
4726 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
4727 "warning: sorry: semantics of inline function static data `const
4728 unsigned char translate_table[262]' are wrong (you'll wind up with
4731 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
4732 or, xor to not_, and_, or_, and xor_, respectively. This works
4733 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
4734 random system header somewhere that includes the equivalent of

4743 During deterministic GLR operation, user actions should be able to
4744 influence the parse by changing yychar. To make this easier to fix and
4745 to make glr.c easier to evolve in general, don't maintain yytoken in
4746 parallel with yychar; just compute yytoken when needed.
4747 * tests/glr-regression.at (Incorrect lookahead during deterministic
4748 GLR): Check that setting yychar in a user action has the intended
4750 * data/glr.c (yyGLRStack): Remove yytokenp member.
4751 (yyclearin): Don't set *yytokenp.
4752 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
4753 yychar rather than *yytokenp to determine the current lookahead.
4754 Compute yytoken locally when needed.
4755 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
4758 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
4759 after `--report' documentation.

4773 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
4774 got from <http://bro-ids.org/download.html>. The bug is that
4775 when two actions appeared in succession, the second one was
4776 scanned before the first one was added to the grammar rule
4777 as a midrule action. Bison then output the incorrect warning
4778 "parse.y:905.17-906.36: warning: unused value: $3".
4779 * src/parse-gram.y (BRACED_CODE, action): These are no longer
4780 associated with a value.
4781 (rhs): Don't invoke grammar_current_rule_action_append.
4782 (action): Invoke it here instead.
4783 * src/reader.c (grammar_midrule_action): Now extern.
4784 (grammar_current_rule_action_append): Don't invoke
4785 grammar_midrule_action; that is now the scanner's job.
4786 * src/reader.h (last_string, last_braced_code_loc):
4787 (grammar_midrule_action): New decls.
4788 * src/scan-gram.l (last_string): Now extern, sigh.
4789 (last_braced_code_loc): New extern variable.
4790 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
4791 rule already has an action.
4792 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
4793 * tests/input.at (AT_CHECK_UNUSED_VALUES):
4794 Add some tests to check that the above changes fixed the bug.
4796 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
4798 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
4799 All used changed. Check whether the symbol has a destructor,
4800 not whether it is typed.
4801 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
4802 that the values are still reported as unused. All line numbers

4849 since we don't want to insist on a version number at the start
4850 of the changelog every time.

5039 (Special Features for Use in Actions): Add YYEOF entry and mention it
5040 in the yychar entry.
5041 In the yychar entry, remove mention of the local yychar case (pure
5042 parser) since this is irrelevant information when writing semantic
5043 actions and since it's already discussed in `Table of Symbols' where
5044 yychar is otherwise described as an external variable.
5045 In the yychar entry, don't call it the `current' look-ahead since it
5046 isn't when semantic actions are deferred.
5047 In the yychar and yyclearin entries, add note about deferred semantic
5049 Add yylloc and yylval entries discussing look-ahead usage.
5050 (Look-Ahead Tokens): When discussing yychar, don't call it the

5073 members to store the current lookahead to be used by the deferred
5075 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
5076 from which the RHS is taken. Set the lookahead members of the new
5077 yySemanticOption according to the lookahead status for stack yyk.

5079 yyaddDeferredAction.
5080 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

5089 char value < 128 in main.
5090 (Incorrect lookahead during deterministic GLR): New test case.
5091 (Incorrect lookahead during nondeterministic GLR): New test case.
5093 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

5102 * tests/glr-regression.at: For consistency with my newer test cases,
5105 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5107 * data/glr.c (yyresolveValue): When merging semantic options, if at
5108 least one user action succeeds but a later one cuts the parse, then
5109 destroy the semantic value before returning rather than leaking it.
5110 (yyresolveStates): If a user action cuts the parse and thus
5111 yyresolveValue fails, ignore the (unset) semantic value rather than
5112 corrupting the yyGLRState, and empty the semantic options list since
5113 the user actions should have called all necessary destructors.
5114 Simplify code with YYCHK.
5115 * tests/glr-regression.at (Corrupted semantic options if user action
5116 cuts parse): New test case.
5117 (Undesirable destructors if user action cuts parse): New test case.
5118 Before applying any of this patch, this test case never actually failed
5119 for me... but only because the corrupted semantic options usually

5163 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain

5169 Warn about dubious constructions like "%token T T".
5171 * src/symtab.h (struct symbol.declared): New member.

5364 destroy the RHS symbols of a rule.
5365 * data/yacc.c (yylen): Initialize to 0.
5366 Keep its value to the number of items to possibly shift.
5367 In particular, a regular successful parse that ends on YYFINAL by
5368 a (internal) YYACCEPT must not have yylen != 0.

5393 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
5395 * bootstrap (build_cvs_prefix): Remove; unused.
5396 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
5397 when getting gnulib.

5415 sed out the final state number.
5417 Work around portability problem on Solaris 10: flex-generated
5418 files include <stdio.h> before <config.h>, which messes up
5419 because the latter defines __EXTENSIONS__. Address the problem
5420 by creating two new little files that include <config.h> first,
5421 then include the flex-generated files. Rewrite everyone else
5422 to include <config.h> first, as well.
5423 * lib/timevar.c: Always include "config.h".
5424 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

5467 All uses of /*CONSTCOND*/0 replaced by YYID(0).
5468 * data/yacc.c: Likewise.
5469 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
5470 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
5471 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
5473 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
5474 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:

5497 * NEWS: Document the following change.
5498 * data/yacc.c: Say "parser skeleton" rather than "file", since
5499 it's no longer just a file.
5500 * data/glr.c: Grant a special exception for C GLR parsers, that
5501 reads like the already-existing exception for C LALR(1) parsers.

5503 * data/lalr1.cc: Likewise.
5504 * data/location.cc: Likewise.

5517 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
5518 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
5519 We can revert this once things settle down.
5521 * src/conflicts.c (conflicts_print): Don't print file name twice
5522 when %expect fails because there were no conflicts.

5762 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
5764 Undo the parts of the unlocked-I/O change that substituted
5765 putc or puts for printf. This might hurt performance a bit,
5766 but some people prefer the printf style.

5797 Use unlocked I/O for a minor performance improvement on hosts like
5798 GNU/Linux and Solaris that support unlocked I/O. The basic idea
5799 is to use the gnlib unlocked-io module, and to prefer putc and
5800 puts to printf when either will work (since the latter doesn't
5801 come in an unlocked flavor).
5802 * bootstrap (gnulib_modules): Add unlocked-io.

5866 2005-10-02 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5868 * lib/subpipe.c: New function end_of_output_subpipe() added
5869 to allow support for non-posix systems. This is a no-op function
5872 * lib/subpipe.h: New function end_of_output_subpipe() added
5873 to allow support for non-posix systems. This is a no-op function
5876 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
5877 handle the lack of pipe/fork functionality on non-posix systems.

5895 2005-10-02 Akim Demaille <akim@epita.fr>
5897 * data/location.cc: New, extract from...
5898 * data/lalr1.cc: here.
5899 (location.hh): Include it after the user prologue, in case the
5900 filename type is defined by the user.
5901 Forward declation location and position before the pre-prologue.
5902 (yyresult_): Rename as...
5903 (yyresult): this, it's a local variable, not an attribute.
5904 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
5906 2005-10-01 Akim Demaille <akim@epita.fr>
5908 * examples/extexi: Restore the #line generation.

5915 (parser::token): New, from the moved free definition of tokens.
5916 (parser::semantic_value): Now a full definition instead of an
5917 indirection to YYSTYPE.
5918 (b4_post_prologue): No longer included in the header file, but
5919 in the implementation file.
5920 * doc/bison.texi (C+ Language Interface): Update.
5921 * src/parse-gram.y: Support unary %define.
5922 * tests/actions.at: Define global_tokens_and_yystype for backward
5923 compatibility until we update the tests.
5924 * tests/calc.at: Idem.
5925 (first_line, first_column, last_line, last_column): Define for lalr1.cc
5926 to simplify the code.
5928 2005-09-29 Paul Eggert <eggert@cs.ucla.edu>
5930 Port to SunOS 4.1.4, which lacks strtoul and strerror.
5931 Ah, the good old days! Problem reported by Peter Klein.
5932 * bootstrap (gnulib_modules): Add strerror, strtoul.
5933 * lib/.cvsignore: Add strerror.c, strtol.c, strtoul.c
5934 * m4/.cvsignore: Add strerror.m4, strtol.m4, strtoul.m4.
5936 2005-09-29 Akim Demaille <akim@epita.fr>

5940 (YYERROR_VERBOSE_IF): Remove.
5941 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
5942 parser members, replaced by...
5943 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
5945 (yysyntax_error_): Takes the state number as argument.
5946 (yyreduce_print_): Use the argument yyrule, not the former
5949 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
5951 * bootstrap (gnulib_modules): Add verify.
5952 * lib/.cvsignore: Add verify.h.

5958 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
5960 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
5961 local variables whose names begin with 'yy'.
5962 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
5963 Trivial changes from Joel E. Denny.
5965 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
5967 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
5968 don't use alloca any more.
5970 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
5971 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
5972 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
5973 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
5974 to match yacc.c, to test more hosts.
5976 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
5978 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
5979 doesn't affect behavior.
5980 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
5982 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
5983 This works a bit better with glibc, if user code has already included
5985 * doc/bison.texinfo (Bison Parser): Document that users can't
5986 arbitrarily use malloc and free for other purposes. Document
5987 that <alloca.h> and <malloc.h> might be included.
5988 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
5989 user must declare alloca.

5998 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
6000 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
6001 (YYSTACK_ALLOC_MAXIMUM): Use it.
6002 (yysyntax_error): New function.
6003 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
6004 multiple syntax errors are reported, and alloca is being used.
6005 Instead, reallocate buffers twice as big each time, so that
6006 we waste at most half the allocated memory. Start with a small
6007 (128-byte) buffer that will suffice in most cases anyway.
6008 Use yysyntax_error to do most of the work.
6010 * doc/bison.texinfo (Error Reporting, Table of Symbols):
6011 yynerrs is the number of errors reported, not the number of
6014 * tests/glr-regression.at (Duplicated user destructor for lookahead):
6015 Mark it as expected to fail.
6016 Cast result of malloc; problem reported by twlevo@xs4all.nl.
6017 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
6018 Don't start user-code symbols with "yy", to avoid name space problems.
6020 2005-09-19 Akim Demaille <akim@epita.fr>
6022 Remove the traits, failed experiment.
6023 It never proved useful, and anyway because of the current
6024 definition, it was not possible to have several specialization of
6025 this traits, making it useless.
6026 * data/lalr1.cc (yy:traits): Remove.
6027 Inline its definitions in the parser class.
6029 2005-09-19 Akim Demaille <akim@epita.fr>

6052 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
6053 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
6054 is not defined. This is an awful hack, but it's enough for now.
6055 All callers changed.
6056 * tests/glr-regression-at (make_value): Args are const pointers now,
6057 to avoid GCC warning.
6058 (Duplicated user destructor for lookahead): New test. Currently
6059 skipped. It fails on my host but I'm not sure it'll always fail.
6061 2005-09-16 Akim Demaille <akim@epita.fr>
6063 * src/symtab.h (struct symbol): Declare the printer and destructor
6064 as const, to avoid accidental calls to free.
6065 (symbol_destructor_set, symbol_printer_set): Adjust.
6066 * src/symtab.c: Adjust.
6068 2005-09-16 Akim Demaille <akim@epita.fr>
6070 * data/c.m4 (b4_token_enums): New.
6071 (b4_token_defines): Rename as...
6072 (b4_token_enums_defines): this.
6073 (b4_token_defines): New, output only the #defines.
6074 * data/yacc.c, data/glr.c: Adjust.
6075 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
6076 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
6079 2005-09-16 Akim Demaille <akim@epita.fr>
6081 * data/lalr1.cc (yylex_): Remove, inline its code.
6082 (yyreport_syntax_error_): Remove, replaced by...
6083 (yysyntax_error_): this which returns a string and leaves to the
6084 caller the call to the users' error function.
6085 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
6086 Move from members of the parser object...
6087 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
6088 to local variables of the parse function.
6090 2005-09-16 Akim Demaille <akim@epita.fr>
6092 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
6093 since it's in Bison's name space.
6095 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
6097 * data/glr.c (yyresolveValue): Add default case to pacify
6098 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
6100 * NEWS: Document when yyparse started to return 2.
6101 * doc/bison.texinfo (Parser Function): Document when yyparse
6104 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
6105 (b4_filename_type): Renamed back from b4_file_name_type. All uses
6107 (class position): file_name -> filename (reverting). All uses changed.
6109 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
6111 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
6112 do anything if $@ exists. This reverts part of the 2005-07-07
6115 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
6117 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
6118 contains obsolete information and isn't worth distributing as a
6119 separate file anyway.
6120 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
6121 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
6122 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
6123 (yyparse): Abort if user code uses longjmp to throw an unexpected
6126 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
6128 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
6129 Suggested by twlevo@xs4all.nl.
6131 * data/glr.c (YYCHK1): Do not assume YYE is in range.
6132 This avoids a diagnostic from gcc -Wswitch-enum.
6133 Problem reported by twlevo@xs4all.nl.
6135 * doc/bison.texinfo: Don't use "filename", as per GNU coding
6136 standards. Use "file name" or "file" or "name", depending on
6138 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
6139 not to hack/foo.tab.c.
6140 (Calc++ Top Level): 2nd arg of main is not const.
6141 * data/glr.c: b4_filename -> b4_file_name.
6142 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

6159 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
6161 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
6164 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6166 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
6167 All uses changed. Invoke user destructor after an error during a
6168 split parse (trivial change from Joel E. Denny).
6170 * tests/glr-regression.at
6171 (User destructor after an error during a split parse): New test case.
6172 Problem reported by Joel E. Denny in:
6173 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
6175 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6177 * README-cvs: Give URLs for recommended tools.
6178 Mention Gzip version problem, and bootstrapping issues.
6179 Remove troubleshooting section, as it's somewhat obsolete.
6181 * bootstrap (no_cache): New var, to accommodate different wget
6182 variants. Use it instead of '-C off'. Problem reported by
6185 * data/glr.c (yydestroyStackItem): New function.
6186 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
6187 debugging information. Problem reported by Joel E. Denny.
6189 2005-08-25 Akim Demaille <akim@epita.fr>
6191 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
6193 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

6196 Don't invoke destructor on unresolved entries.
6197 * tests/glr-regression.at
6198 (User destructor for unresolved GLR semantic value): New test case.
6199 Problem reported by Joel E. Denny in:
6200 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
6202 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
6204 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
6206 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
6207 lib-prefix.m4, po.m4.
6209 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
6210 in yydestruct diagnostic, since it might not be an error.
6211 Problem reported by Joel Denny near end of
6212 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6213 * data/lalr1.cc (yyerturn): Likewise.
6214 * data/yacc.c (yyreturn): Likewise.
6215 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
6217 * src/files.c: Remove obsolete FIXME comment.
6219 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
6220 with the other templates, and to fix bogus run-on messages such
6221 as the one reported at the end of
6222 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6223 All callers changed to avoid the newline.
6224 (yyprocessOneStack): Output two lines rather than one, to accommodate
6225 the above change. This changes the debug output format slightly.
6227 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
6228 reported by Joel E. Denny in
6229 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
6231 * tests/glr-regression.at (Duplicate representation of merged trees):
6232 New test, from Joel E. Denny in:
6233 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
6234 * THANKS: Add Joel E. Denny.
6236 * configure.ac (AC_INIT): Bump to 2.0c.
6238 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
6240 * NEWS: Version 2.0b.
6242 * Makefile.am (SUBDIRS): Put examples before tests, so that
6243 "make check" doesn't finish with "All 1 tests passed".
6245 * tests/regression.at (Token definitions): Don't rely on
6246 AT_PARSER_CHECK for data that contains backslashes. It currently
6247 uses 'echo', and 'echo' isn't portable if its argument contains
6248 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
6249 that the byte '\0xff' is not printable in the C locale; it is,
6250 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
6251 not printable, so use '\0x81' to test.
6253 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
6254 version of GCC, since the macro is used with non-GCC compilers.
6256 Fix core dump reported by Pablo De Napoli in
6257 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
6258 * tests/regression.at (Invalid inputs with {}): New test.
6259 * src/parse-gram.y (token_name): Translate type before using
6262 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
6263 the user's name space. All uses changed to __attribute__
6265 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
6266 Add __attribute__ ((__noreturn__)).
6268 * etc/clcommit: Remove. We weren't using it, and it failed
6269 "make maintainer-distcheck".
6270 * Makefile.maint: Merge from coreutils.
6271 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
6272 (syntax-check-rules): Change list of rules as described below.
6273 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

6281 (makefile-check, po-check, author_mark_check):
6282 (makefile_path_separator_check, copyright-check):
6283 Use grep -n, to make it easier to find violations.
6284 Use CVS_LIST and CVS_LIST_EXCEPT.
6285 (header_regexp, h_re): Remove.
6287 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
6288 (my-distcheck): Use more-modern GCC flags.
6289 (signatures, %.asc): Remove.
6290 (rel-files, announcement): Remove signatures.
6291 Restore old updating code, even though we don't use it, so
6292 that we're the same as coreutils.
6293 (alpha, beta, major): Depend on news-date-check.
6294 Make the upload commands.
6296 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

6303 * tests/sets.at: Likewise.
6305 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
6306 we comment out the Autoconf version number.
6307 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
6308 it's error-prone and "make maintainer-distcheck" rejects it.
6310 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
6311 Indent calls to "error" to pacify "make maintainer-distcheck",
6312 when the calls are not intended to be translated.
6313 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
6315 * src/Makefile.am (DEFS): Use +=, to pacify
6316 "make maintainer-distcheck".
6317 (bison_SOURCES): Add scan-skel.h.
6318 (sc_tight_scope): New rule, from coreutils.
6320 * src/files.c (src_extension, header_extension):
6321 Now static, not extern.
6322 * src/getargs.c (short_options): Likewise.
6323 * src/muscle_tab.c (muscle_table): Likewise.
6324 * src/parse-gram.y (current_class, current_type, current_prec):
6326 * src/reader.c (grammar_end, previous_rule_end): Likewise.
6327 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
6328 * src/main.c (main): Cast bindtextdomain and textdomain calls to
6329 void, to avoid warning when NLS is disabled.
6330 * src/output.c: Include scan-skel.h.
6331 (scan_skel): Remove decl, since scan-skel.h does this.
6333 Indent calls to "error" to pacify "make maintainer-distcheck".
6334 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
6335 * src/reader.h (gram_end, gram_lineno): New decls to pacify
6336 "make maintainer-distcheck".
6337 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
6338 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
6339 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
6340 (skel_lex_destroy, scan_skel): Move these decls to...
6341 * src/scan-skel.h: New file.
6342 * src/uniqstr.c (uniqstr_assert):
6343 Indent calls to "error" to pacify "make maintainer-distcheck".
6345 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
6348 * tests/torture.at: Revamp to avoid misuse of atoi that
6349 "make maintainer-distcheck" complained about.
6351 * examples/extexi (message): Don't print a message more than once,
6352 and omit line-number decoration that makes Emacs compile think
6353 that informative messages are worth worrying about.
6355 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
6357 * configure.ac: Update version number.
6359 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
6361 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
6362 autogenerated by the maintainer.
6363 * examples/calc++/.cvsignore: Add *.yy.
6365 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
6366 * lib/bitset_stats.c (bitset_stats_init): Likewise.
6367 * lib/bitsetv.c (bitsetv_alloc): Likewise.
6369 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
6371 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
6372 from maintainer-distcheck about casting the argument of 'free'.
6374 * NEWS: Mention recent yytname changes.
6375 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
6377 * bootstrap: For translations that have not yet been upgraded to
6378 the new runtime-po domain, prime the pump by extracting the
6379 relevant strings from the obsolete translations. This code can be
6380 removed once the bison-runtime domain has been translated by each
6383 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
6384 now that token names are already quoted.
6386 Fix problem reported by Anthony Heading.
6387 * data/glr.c (YYTOKEN_TABLE): New macro.
6388 (yytname): Define if YYTOKEN_TABLE.
6389 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
6390 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
6391 (YYERROR_VERBOSE): Define the same way the other skeletons do.
6392 * src/output.c (prepare_symbols): Output token_table_flag.
6394 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
6396 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
6397 again if the first call fails.
6399 * data/glr.c (yytnamerr): New function.
6400 (yyreportSyntaxError): Use it to dequote most string literals.
6401 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
6402 with other skeletons. All uses changed.
6403 (yytnameerr_): New function.
6404 (yyreport_syntax_error): Use it to dequote most string literals.
6405 * data/yacc.c (yytnamerr): New function.
6406 (yyerrlab): Use it to decode most string literals.
6407 * doc/bison.texinfo (Decl Summary, Calling Convention):
6408 Clarify quoting convention of yytname.
6409 * src/output.c (prepare_symbols): Quote all names. This undoes
6410 the 2005-04-17 change, which is now accomplished (mostly) via
6411 changes in the parsers as described above.
6412 * tests/regression.at (Token definitions, Web2c Actions):
6413 Undo most 2005-04-17 change here, too.
6415 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
6417 Fix more problems reported by twlevo@xs4all.nl.
6418 * tests/cxx-type.at: Don't pipe output of ./types through sed to
6419 remove trailing spaces. This loses the exit status of ./types,
6420 and isn't needed since ./types shouldn't be emitting trailing
6422 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
6423 as the stack isn't valid in that case.
6425 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6426 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6427 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6428 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
6430 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
6431 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
6432 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
6435 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
6436 overly-picky compilers that reject 'char *foo = "bar";'.
6438 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
6439 to FILE * parameter, not to stderr. This fixes a typo introduced
6440 in the 2005-07-12 change.
6442 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
6443 warnings from GCC 4.
6445 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
6446 (yyglrShiftDefer, yysplitStack):
6447 Remove unused parameters b4_pure_formals. All uses changed.
6448 (yyglrShift): Remove unused parameters b4_user_formals.
6450 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
6452 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
6454 Destructor cleanups and regularization among the three skeletons.
6455 * NEWS: Document the behavior changes.
6456 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
6457 stack before failing, as the cleanup code will do it for us now.
6458 * data/lalr1.cc (yyerrlab): Likewise.
6459 * data/glr.c (yyparse): Pop everything off the stack before
6460 freeing it, so that destructors get called properly.
6461 * data/lalr1.cc (yyreturn): Likewise.
6462 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
6463 This is more consistent.
6464 * doc/bison.texinfo (Destructor Decl): Mention more reasons
6465 why destructors might be called. 1.875 -> 2.1.
6466 (Destructor Decl, Decl Summary, Table of Symbols):
6467 Some English-language cleanups for %destructor.
6468 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6469 Add output line for destructor of start symbol.
6470 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
6471 because of that same extra output line.
6473 * NEWS: Document minor wording changes in diagnostics of
6474 Bison-generated parsers.
6475 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
6476 Remove unused formals. All uses changed.
6477 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
6478 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
6479 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
6480 Rename yyoverflowab to yyexhaustedlab.
6481 When memory exhaustion occurs during syntax-error reporting,
6482 report it separately rather than in a single diagnostic; this
6484 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
6485 (Memory Exhausted): Renamed from Parser Stack Overflow.
6486 Revamp wording slightly to prefer "memory exhaustion".
6487 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
6489 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
6491 Add i18n support to the GLR skeleton. Partially fix the C++
6492 skeleton; a C++ expert needs to finish this. Remove debugging
6493 msgids; there's little point to having them translated, since they
6494 can be understood only by someone who can read the
6495 (English-language) source code.
6497 Generate runtime-po/bison-runtime.pot automatically, so that we
6498 don't have to worry about garbage getting in that file. We'll
6499 make sure after the next official release that old msgids don't
6501 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
6503 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
6505 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
6506 Fix typos in explanations of the runtime file.
6507 * bootstrap: Change gettext keyword from YYI18N to YY_.
6508 Use standard Makefile.in.in in runtime-po, since we'll arrange
6509 for backward-compatible bison-runtime.po files in a different way.
6510 * data/glr.c (YY_): New macro, from yacc.c.
6511 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
6512 Translate messages intended for users.
6513 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
6514 the wording in the other skeletons. We don't know that the memory
6516 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
6517 Use same method that yacc.c uses.
6518 Don't translate debugging messages.
6519 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
6520 it doesn't work (yet), and requires C++ expertise to fix.
6521 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
6522 Move defn to a more logical place, to be consistent with other
6524 Don't translate debugging messages.
6525 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
6526 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
6527 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
6528 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
6530 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
6531 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
6533 * tests/glr-regression.at (Badly Collapsed GLR States):
6535 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6536 yylex should return 0 at EOF rather than aborting.
6538 Improve tests for stack overflow in GLR parser.
6539 Problem reported by twlevo@xs4all.nl.
6540 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
6542 (yyStackOverflow): Just longjmp, but with value 2 so that caller
6543 can handle the problem.
6544 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
6545 (yyparse): New local variable yyresult to record the result.
6546 Use result of setjmp to set it, rather than storing itinto
6548 (yyDone): Remove label.
6549 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
6550 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
6551 if YYABORT is used).
6552 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
6553 yyparse status; put status > 1 into diagnostic.
6554 Check that status==2 works.
6555 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
6556 Use exit status 3 for failure to open (which shouldn't happen).
6558 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
6560 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
6561 1 on syntax error; just let yyparse do its thing.
6562 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
6563 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
6564 (Exploding the Stack Size with Alloca):
6565 (Exploding the Stack Size with Malloc):
6566 Expect exit status 2, not 1, since the parser is supposed to blow
6567 its stack. Problem reported by twlevo@xs4all.nl.
6569 * data/glr.c (yyparse): Don't assume that the initial calls
6570 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
6571 Print a stack-overflow message and fail instead.
6572 Initialize the line-number information before creating the stack,
6573 so that the stack-overflow message can report line zero safely.
6575 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
6577 Fix problems reported by twlevo@xs4all.nl.
6578 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
6579 (yyuserMerge): Provide a default case if b4_mergers is empty.
6580 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
6581 * tests/glr-regression.at
6582 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6583 Add casts to pacify C++ compilers.
6584 * tests/glr-regression.at (Improper merging of GLR delayed action
6585 sets): Declare yylex before using it.
6586 * tests/Makefile.am (maintainer-check-g++): Fix a stray
6587 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
6588 test for valgrind; valgrind is independent of g++.
6589 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
6590 for compatibility with POSIX 1003.1-2001 (if running coreutils).
6591 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
6592 Use a destructor, so that we can expand the stack. Change
6593 YYSTYPE to char * so that we can free it. Cast result of malloc.
6595 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
6597 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
6598 a valgrind failure. Problem reported by twlevo@xs4all.nl.
6600 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
6602 * PACKAGING: New file, suggested by Bruno Haible and taken from
6603 similar wording in gettext's PACKAGING file.
6604 * NEWS: Mention PACKAGING.
6605 * Makefile.am (EXTRA_DIST): Add PACKAGING.
6607 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
6609 * NEWS: Document recent i18n improvements.
6610 * bootstrap: Get runtime translations into runtime-po.
6611 Create runtime-po files automatically, if possible.
6612 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
6613 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
6614 does not infringe on the user's name space.
6615 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
6616 * doc/bison.texinfo (Internationalization): Revamp the English
6617 and Texinfo syntax a bit, to try to make it clearer.
6618 (Bison Options, Option Cross Key): Mention --print-localedir.
6619 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
6620 YYENABLE_NLS. Quote a bit more.
6621 * runtime-po/.cvsignore: New file.
6622 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
6623 * runtime-po/Rules-quot: Remove; now created by bootstrap.
6624 * runtime-po/quot.sed: Likewise.
6625 * runtime-po/boldquot.sed: Likewise.
6626 * runtime-po/en@quot.header: Likewise.
6627 * runtime-po/en@boldquot.header: Likewise.
6628 * runtime-po/insert-header.sin: Likewise.
6629 * runtime-po/remove-potcdate.sin: Likewise.
6630 * runtime-po/Makevars: Likewise.
6631 * runtime-po/LINGUAS: Likewise.
6632 * runtime-po/de.po: Likewise; we will rely on the translation project
6633 to maintain this, so "bootstrap" should get it.
6634 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
6636 * src/main.c (main): Bind the bison-runtime domain, too.
6638 2005-07-12 Bruno Haible <bruno@clisp.org>
6640 * data/yacc.c: Include <libintl.h> when NLS is enabled.
6641 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
6642 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
6643 * runtime-po: New directory.
6644 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
6645 $(DOMAIN).pot-update rule, so that old messages are never dropped.
6646 * runtime-po/Rules-quot: New file, copied from po/.
6647 * runtime-po/quot.sed: Likewise.
6648 * runtime-po/boldquot.sed: Likewise.
6649 * runtime-po/en@quot.header: Likewise.
6650 * runtime-po/en@boldquot.header: Likewise.
6651 * runtime-po/insert-header.sin: Likewise.
6652 * runtime-po/remove-potcdate.sin: Likewise.
6653 * runtime-po/Makevars: New file.
6654 * runtime-po/POTFILES.in: New file.
6655 * runtime-po/LINGUAS: New file.
6656 * runtime-po/bison-runtime.pot: New file.
6657 * runtime-po/de.po: New file.
6658 * m4/bison.m4: New file.
6659 * Makefile.am (SUBDIRS): Add runtime-po.
6660 (aclocaldir, aclocal_DATA): New variables.
6661 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
6663 * src/getargs.c (usage): Document --print-localedir option.
6664 (PRINT_LOCALEDIR_OPTION): New enum item.
6665 (long_options): Add --print-localedir option.
6666 (getargs): Handle --print-localedir option.
6667 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
6668 (Internationalization): New section.
6670 2005-07-12 Akim Demaille <akim@epita.fr>
6672 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
6673 for consistency with the rest of the code.
6674 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
6677 2005-07-12 Akim Demaille <akim@epita.fr>
6679 * src/parse-gram.y: Use %printer instead of YYPRINT.
6681 2005-07-12 Akim Demaille <akim@epita.fr>
6683 * src/symtab.h, src/symtab.c (symbol_print): New.
6684 * src/symlist.h, src/symlist.c (symbol_list_print): New.
6685 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
6687 2005-07-12 Akim Demaille <akim@epita.fr>
6689 * data/glr.c (b4_syncline): Fix (swap) the definitions of
6690 b4_at_dollar and b4_dollar_dollar.
6692 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
6694 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
6695 and Pennello's paper.
6697 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
6699 * data/yacc.c (yyparse): Undo previous patch. Instead,
6700 set yylsp[0] and yyvsp[0] only if the initial action
6701 sets yylloc and yylval, respectively.
6703 * data/yacc.c (yyparse): In the initial action, set
6704 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
6705 This avoids the use of undefined variables if the initial
6706 action does not set yylloc and/or yylval.
6708 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6710 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
6711 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
6712 Remove from CVS. These files are automatically generated.
6713 * examples/extexi: Clarify that this file is now part of Bison,
6714 not GNU M4, and that it works with any POSIX-compatible Awk.
6715 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
6716 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
6717 so that we also get calc++-parser.yy. Geneate it.
6718 Use $(AWK), not gawk, since any conforming Awk will do.
6719 Put comment before action, since older 'make' can't handle comment
6721 $(BUILT_SOURCES): List all built sources, not just some of them.
6722 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
6723 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
6724 $($(calc_sources_generated)): Remove unnecessary test for existence
6725 of target. (This had a shell syntax error anyway; a stray "x".)
6726 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
6728 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
6730 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
6731 implied by the other modules.
6733 2005-07-06 Akim Demaille <akim@epita.fr>
6735 Bind examples/calc++ to the package.
6736 * examples/calc++/Makefile: Remove, replaced by...
6737 * examples/calc++/Makefile.am: ... this new file.
6738 * examples/calc++/test: Remove input.
6739 * examples/calc++/compile: Remove.
6740 * examples/Makefile.am: New.
6741 * configure.ac, Makefile.am: Adjust.
6742 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
6744 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
6746 * data/glr.c (yyFail): Drastically simplify; since the format argument
6747 never had any % directives, we can simply pass it to yyerror.
6748 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
6749 be modified later, as that is the usual style in glr.c.
6750 Problems reported by Paul Hilfinger.
6752 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
6753 and size overflow errors.
6754 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
6755 in case the user prolog sets feature-test macros like _GNU_SOURCE.
6756 (YYSIZEMAX): New macro.
6757 (yystpcpy): New function, taken from yacc.c.
6758 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
6759 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
6760 so that we don't have to maintain their signatures.
6761 (yyFail): Check for buffer overflow, by using vsnprintf rather
6762 than vsprintf. Allocate a bigger buffer if possible.
6763 Report an error if buffer allocation fails.
6764 (yyStackOverflow): New function.
6765 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
6766 the initialization was successful. It might fail if storage was
6768 (yyexpandGLRStack): Add more checks for storage allocation failure.
6769 Use yyStackOverflow to report failures.
6770 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
6771 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
6772 Don't assume stack number fits in int.
6773 (yysplitStack): Check for storage allocation failure.
6774 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
6775 can print diagnostics on storage allocation failure. All callers

6820 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
6822 * data/glr.c: Modify treatment of unused parameters to permit use

6837 Fix infringement on user name space reported by Bruno Haible.
6838 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
6839 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
6840 the user's name space.
6841 (alloca): Include <stdlib.h> to get it, if it's not built in.
6842 (YYMALLOC, YYFREE): Define only if needed.
6843 (malloc, free): Declare, but only if needed, as this infringes on
6844 the user name space.
6846 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
6848 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.

6871 * NEWS: Version 2.0a.
6873 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
6874 the previous change.
6876 Various maintainer cleanups.
6877 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
6878 conftest*, for benefit of CVS commands run at the same time as
6879 "configure". Add build-aux, since "bootstrap" now creates it and
6881 * Makefile.cfg (move_if_change): Remove.
6882 * Makefile.maint: Remove the update stuff; we now use "bootstrap".

6904 (create_subpipe): Make sure all the newly-created
6905 file descriptors are > 2, so that diagnostics don't
6906 get sent down them (which might cause Bison to hang, in theory).
6907 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
6908 * src/files.c (xfopen): Use fopen_safer, not fopen.

6922 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
6923 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,

6986 Problem reported by Ralf Menzel.
6988 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6990 * tests/actions.at: Test that stack overflow invokes destructors.
6991 From Marcus Holland-Moritz.
6992 * data/yacc.c (yyerrlab): Move the code that destroys the stack
6994 (yyreturn): to here. That way, destructors are called properly
6995 even if the stack overflows, or the user calls YYACCEPT or
6996 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
6997 (yyoverflowlab): Destroy the lookahead.
6999 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
7001 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
7003 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
7005 * NEWS: Bison-generated C parsers no longer quote literal strings
7006 associated with tokens.
7007 * src/output.c (prepare_symbols): Don't escape strings,
7008 since users don't want to see C escapes.

7011 * tests/input.at (Torturing the Scanner): Likewise.
7012 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
7014 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
7016 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
7017 the data size is known to be too small and we can't increase it.
7018 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
7020 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
7022 * src/parse-gram.y: Include quotearg.h.
7023 (string_as_id): Quote $1 before using it as a key, since the
7024 lexer no longer quotes it for us.
7025 (string_content): Don't strip quotes, since lexer no longer
7027 * src/scan-gram.l: Include quotearg.h.
7029 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
7030 a key, since the rest of the lexer doesn't quote it.

7032 * tests/regression.at (Token definitions): Check for backslashes
7035 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
7036 (YYSIZE_T): Define to unsigned long int when using an older compiler.
7037 (yyparse): Revamp code to generate long syntax error message, to
7038 make it easier to translate, and to avoid problems with arithmetic
7039 overflow. Change "virtual memory" to "memory" in diagnostic, since
7040 we don't know whether the memory is virtual.
7042 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7044 * NEWS: Bison-generated C parsers now use the _ macro to
7046 * data/yacc.c (_) [!defined _]: New macro.
7047 All English strings wrapped inside this macro.
7048 * doc/bison.texinfo (Bison Parser): Document _.
7049 * po/POTFILES.in: Include src/parse-gram.c, since it now
7050 includes translateable strings that parse-gram.y doesn't.
7052 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
7054 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
7055 reverting the 2004-10-11 change to this function.
7056 (symbol_check_alias_consistency): Don't call symbol_type_set
7057 if the type name is already correct.
7058 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
7060 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
7062 * tests/regression.at (Token definitions): Don't use a token named
7063 c, as that generates a "#define c ..." that runs afoul of buggy
7064 stdlib.h that uses the identifier c as a member of struct
7065 drand48_data. Problem reported by Horst Wente.
7067 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
7069 * bootstrap: Change translation URL from
7070 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
7071 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
7072 redirection glitches. Problem reported by twlevo@xs4all.nl.
7074 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
7076 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
7077 after operands; POSIX says this isn't portable for the c99 command.
7079 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
7081 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
7082 immediately if a data overrun has occurred; this may help us track
7083 down what may be a spurious failure on MacOS.
7085 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
7087 Respond to problems reported by twlevo@xs4all.nl.

7100 "#if 0", since it's not currently used. Problem reported by
7103 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
7105 * src/output.c (escaped_output): Renamed from
7106 escaped_file_name_output, since we now use it for symbol tags as
7107 well. All uses changed.
7108 (symbol_destructors_output, symbol_printers_output):
7109 Escape symbol tags too.
7110 Problem reported by Matyas Forstner in
7111 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
7113 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
7115 * src/output.c (user_actions_output, token_definitions_output,
7116 symbol_destructors_output, symbol_printers_output): Likewise.
7117 * src/reader.c (prologue_augment): Likewise.
7118 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
7120 * src/vcg.c (output_edge): Don't quote linestyle arg.
7121 Problem reported by twlevo@xs4all.nl.
7123 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
7125 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
7126 example, reported by Derek M Jones. Also, make the example even
7127 more outrageous, to better illustrate how bad the problem is.
7129 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
7131 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
7132 putsym. Typo reported by Sebastian Piping.
7134 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7136 * doc/bison.texinfo (Language and Grammar): some -> same
7137 (Epilogue): int he -> in the
7138 Typos reported by Sebastian Piping via Justin Pence.
7140 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7142 * tests/glr-regression.at (Improper handling of embedded actions
7143 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
7144 embedded actions and $-N in GLR parsers", work around an Autoconf bug
7145 with dollar signs in test names.
7146 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
7147 for a similar reason.
7149 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7151 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
7152 wants to redefine G_VIEW.

7175 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
7176 keyword; it's not needed with modern compilers, and it doesn't
7177 affect correctness with older compilers. Suggested by
7180 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
7182 * data/glr.c (yyuserAction): Add "default: break;" case to pacify

7194 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
7195 for the benefit of slower hosts. Problem reported by
7198 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
7200 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
7201 being defined and not used.
7202 * data/lalr1.cc (yyparse): Likewise.
7203 Use "if (false)" rather than "if (0)".

7232 * NEWS: Version 2.0. Reformat the existing news items since
7233 1.875, so that related items are grouped together.
7234 * configure.ac (AC_INIT): Bump version to 2.0.
7235 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
7237 * tests/torture.at (Exploding the Stack Size with Alloca): Set
7238 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
7239 otherwise, we're not testing alloca. Unfortunately there's no
7240 simple way to consult HAVE_ALLOCA here.
7242 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
7245 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
7246 hand. This avoids a warning about comparing int to size_t when
7247 GCC warnings are enabled.
7249 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
7251 * NEWS: Bison-generated parsers no longer default to using the
7252 alloca function (when available) to extend the parser stack, due
7253 to widespread problems in unchecked stack-overflow detection.
7254 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
7255 responsibility to set it to a positive value. This lets the user
7256 specify a value that is not a preprocessor constant.
7257 * data/yacc.c (YYMAXDEPTH): Likewise.
7258 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
7259 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
7260 to be a compile-time constant. However, explain the constraints on it.
7261 Also, explain the constraints on YYINITDEPTH.
7262 (Table of Symbols): Explain that alloca is no longer the default.
7263 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
7266 * doc/bison.texinfo (Location Default Action): Mention that n must
7267 be zero when k is zero. Suggested by Frank Heckenbach.
7269 2004-12-22 Akim Demaille <akim@epita.fr>
7271 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
7272 (parser::state_type, parser::semantic_type, parser::location_type):
7273 Private, not public.
7274 (parser::parse): Return ints, not bool.
7275 Returning a bool introduces a problem: 0 corresponds to false, and
7276 it seems weird to return false on success. Returning true changes
7277 the conventions for yyparse.
7278 Alternatively we could return void and send an exception.
7279 There is no clear consensus (yet?).
7280 (state_stack, semantic_stack, location_stack): Rename as...
7281 (state_stack_type, semantic_stack_type, location_stack_type): these.
7282 Private, not public.
7283 * tests/c++.at: New.
7284 * tests/testsuite.at, tests/Makefile.am: Adjust.
7286 2004-12-21 Akim Demaille <akim@epita.fr>
7288 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
7290 2004-12-21 Akim Demaille <akim@epita.fr>
7292 Don't impose std::string for filenames.
7294 * data/lalr1.cc (b4_filename_type): New.
7295 (position::filename): Use it.
7296 (parser.hh): Move the inclusion of stack.hh and location.hh below
7297 the user code, so that needed headers for the filename type can be
7299 Forward declare them before the user code.
7300 * tests/Makefile.am (check-local, installcheck-local): Pass
7301 TESTSUITEFLAGS to the TESTSUITE.
7303 2004-12-20 Akim Demaille <akim@epita.fr>
7305 Use more STL like names: my_class instead of MyClass.
7307 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
7308 (SemanticStack, SemanticType, StateStack, StateType)
7309 (TokenNumberType, Stack, Slice, Traits, Parser::location)
7310 (Parser::value): Rename as...
7311 (location_stack, location_type, rhs_number_type, semantic_stack)
7312 (semantic_type, state_stack, state_type, token_number_type, stack)
7313 (slice, traits, parser::yylloc, parser::yylval): these.
7315 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
7317 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
7319 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
7320 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
7322 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
7324 Remove uses of 'short int' and 'unsigned short int'. This raises
7325 some arbitrary limits. It uses more memory but nowadays that's
7326 not much of an issue.
7328 This change does not affect the generated parsers; that's a different
7329 task, as some users will want to conserve memory there.
7331 Ideally we should use size_t to represent all object counts, and
7332 something like ptrdiff_t to represent signed differences of object
7333 counts; but that will require more code-cleanup than I have the
7334 time to do right now.
7336 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
7337 Use size_t, not int or short int, to count objects.
7338 * src/closure.c (nritemset, closure): Likewise.
7339 * src/closure.h (nritemset, closure): Likewise.
7340 * src/nullable.c (nullable_compute): Likewise.

7350 errs, reductions): Likewise.
7351 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
7353 * src/tables.c (vector_number, tally, action_number,
7354 ACTION_NUMBER_MINIMUM): Likewise.
7355 * src/output.c (muscle_insert_short_int_table): Remove.
7357 2004-12-17 Akim Demaille <akim@epita.fr>
7359 * data/lalr1.cc: Extensive Doxygenation.
7360 (error_): Rename as...
7361 (error): this, since it is visible to the user.
7363 (Parser::message): Now an automatic variable from...
7364 (Parser::yyreport_syntax_error_): here.
7365 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
7367 * tests/input.at: Escape $.
7369 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
7371 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
7372 Parenthesize rhs to avoid obscure problems with mistakes like
7373 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
7374 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
7375 b4_rhs_location): Likewise.
7376 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
7377 b4_rhs_location): Likewise.
7379 2004-12-16 Akim Demaille <akim@epita.fr>
7381 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
7382 yacc.c: be sure to stay within yycheck_.
7383 * tests/actions.at: Re-enable C++ tests.
7385 2004-12-16 Akim Demaille <akim@epita.fr>
7387 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
7390 2004-12-16 Akim Demaille <akim@epita.fr>
7392 Use #define to handle the %name-prefix.
7394 * data/glr.c, data/yacc.c: Comment changes.
7395 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
7396 so that one can refer to yylex in the parser file, and have it
7397 renamed, as is the case with other skeletons.
7399 2004-12-16 Akim Demaille <akim@epita.fr>
7401 Move lalr1.cc internals into yy*.

7421 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
7423 Fix some problems reported by twlevo at xs4all.
7424 * src/symtab.c (symbol_new): Report an error if the input grammar
7425 contains too many symbols. This is better than calling abort() later.
7426 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
7427 (struct node, struct graph):
7428 Rename member expand to stretch. All uses changed.
7429 (struct graph): Remove member layoutalgorithm. All uses removed.
7430 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
7431 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.

7435 2004-12-15 Akim Demaille <akim@epita.fr>
7437 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
7438 Add more Doxygen comments.
7439 (symprint_, stack_print_, reduce_print_, destruct_, pop)
7440 (report_syntax_error_, translate_): Rename as...
7441 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
7442 (yypop_, yyreport_syntax_error_, yytranslate_): this.
7444 2004-12-15 Akim Demaille <akim@epita.fr>
7446 * data/lalr1.cc (lex_): Rename as...
7448 Move the trace here.
7449 Take the %name-prefix into account.
7450 Reported by Alexandre Duret-Lutz.
7452 2004-12-15 Akim Demaille <akim@epita.fr>
7454 Simplify the C++ parser constructor.
7456 * data/lalr1.cc (debug_): Rename as...
7457 (yydebug_): so that the parser's internals are always in the yy*
7460 (b4_parse_param_decl): Remove the leading comma as it is now only
7461 called as unique argument list.
7462 (Parser::Parser): Remove the constructor accepting a location and
7463 an initial debugging level.
7464 Remove from the other ctor the argument for the debugging level.
7465 (debug_level_type, debug_level, set_debug_level): New.
7467 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
7470 2004-12-15 Akim Demaille <akim@epita.fr>
7472 Remove b4_root related material: failure experiment
7473 (which goal was to allow to derive from a class).
7475 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
7476 definitions and uses.
7478 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
7480 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
7481 not 2, since it's not portable to subtract 1 from the start of an
7482 array. The new item 0 is never set or used. All uses changed.
7484 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
7485 the default definition of YYLLOC_DEFAULT. Problem reported
7486 by Frank Heckenbach.
7488 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
7490 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
7491 the normal case and one for the error case. Just use the
7492 first one uniformly. Problem reported by Frank Heckenbach.
7493 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
7494 use exactly the same macro in both places.
7495 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
7496 so that the normal-case YYRHSLOC works for the error case too.
7498 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
7499 (YYLLOC_DEFAULT): Use the same macro as glr.c.
7500 * doc/bison.texinfo (Location Default Action): Don't claim that
7501 we have an array of locations. Use the same macro for both glr
7502 and lalr parsers. Mention YYRHSLOC. Mention what happens when
7505 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
7507 * HACKING: Update email addresses to send announcements to.
7509 * configure.ac (AC_INIT): Bump version to 1.875f.

7514 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
7516 * src/scan-skel.l: Include "complain.h", for "fatal".
7518 * src/relation.h (relation_print, relation_digraph):
7519 Relation sizes are of type relation_node, not size_t (this is
7520 merely a doc fix, since the two types are equivalent).
7521 (relation_transpose): Relation sizes are of type relation_node,
7523 * src/relation.c: Likewise.
7524 (top, infinity): Now of type relation_node, not int.
7525 (traverse, relation_transpose): Use relation_node, not int.
7527 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
7528 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
7529 (yyparse): Remove unused local introduced in 2004-10-25 patch.
7531 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
7532 specifying whether the test should be skipped. Use it tp
7533 specify that the [%defines %skeleton "lalr1.cc"] tests currently
7534 fail on some hosts, and should be skipped.
7536 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
7538 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
7539 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
7540 unless otherwise specified below.
7542 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
7543 to allocate kernel_base, kernel_items, kernel_size, since
7544 they needn't be initialized to 0.
7545 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
7546 * src/closure.c (new_closure): Likewise, for itemset.
7547 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

7562 (goto_actions): Likewise for state_count.
7563 (pack_table): Likewise for base, pos, check.
7564 (tables_generate): Likewise for width.
7566 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
7567 for initial core. Just have a separate core, so we needn't worry
7568 about whether kernel_size and kernel_base are initialized.
7570 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
7571 kernel_size, kernel_items): Remove unnecessary initialization.

7576 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
7577 conflrow, conflict_table, conflict_list, table, check):
7580 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
7581 This is because all callers pass unsigned int.
7582 * src/closure.h (new_closure): Likewise.
7584 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
7585 (build_relations): Initialize includes[i] in all cases.
7586 * src/reader.c (packgram): Always initialize rules[ruleno].prec
7587 and rules[ruleno].precsym. Initialize members in order.
7588 * src/relation.c (relation_transpose): Always initialize new_R[i]
7590 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
7592 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
7593 conflict_list[0] was always 0, but now it isn't initialized.
7595 * src/table.c (table_grow): When conflict_table grew, the grown
7596 area wasn't cleared. Fix this.
7598 * lib/.cvsignore: Add strdup.c, strdup.h.
7599 * m4/.cvsignore: Add strdup.m4.
7601 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
7603 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
7604 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
7605 GOTO_NUMBER_MAXIMUM, since we occasionally compute
7606 ngotos + 1 without checking for overflow.
7607 (build_relations): Use END_NODE, not -1, to denote end of edges.
7608 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
7609 build_relations): Use goto_number, not int, for goto numbers.

7614 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
7615 of #defining from yystype.
7616 Don't typedef yystype, C++ does not need it.
7617 This lets it possible to forward declare it as union.
7619 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
7621 * bootstrap (gnulib_modules): Add extensions.
7622 Problem reported by Jim Meyering.

7659 Problem reported by Frank Heckenbach.
7661 2004-10-25 Akim Demaille <akim@epita.fr>
7663 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
7664 Introduce another definition to address simple location arrays.
7665 (yyGLRStack): New member: yyerror_range.
7666 (yyrecoverSyntaxError, yyparse): Update it.
7667 (yyrecoverSyntaxError): Use it when shifting the error token to
7668 have an accurate range, equivalent to the one computed by both
7669 yacc.c and lalr1.cc.
7670 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
7671 that column numbers start at column 0, as per GNU Coding
7672 Standards, the others tests, and the doc.
7673 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
7674 Adjust to the above change (first column is 0).
7675 And adjust the location of the "<error>", now covering the whole
7678 2004-10-22 Akim Demaille <akim@epita.fr>
7679 and Paul Eggert <eggert@cs.ucla.edu>
7681 Remove some arbitrary limits on goto numbers and relations.
7682 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
7683 initial values, since they're never used.
7684 (set_goto_map): ngotos is now unsigned, so test for overflow
7685 by seeing whether it wraps around to zero.
7686 * src/lalr.h (goto_number): Now size_t, not short int.
7687 (GOTO_NUMBER_MAXIMUM): Remove.
7688 * src/relation.c (relation_print, traverse, relation_transpose):
7689 Check for END_NODE rather than looking at sign.
7690 * src/relation.h (END_NODE): New macro.
7691 (relation_node): Now size_t, not short int.
7693 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
7695 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
7696 keyword, not an identifier. Problem reported by Baron Schwartz in
7697 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
7699 2004-10-11 Akim Demaille <akim@epita.fr>
7701 * src/symtab.c (symbol_check_alias_consistency): Also check
7702 type names, destructors, and printers.
7703 Reported by Alexandre Duret-Lutz.
7704 Recode the handling of associativity and precedence in terms
7705 of symbol_precedence_set.
7706 Accept no redeclaration at all, not even equal to the previous
7708 (redeclaration): New.
7709 Use it to factor redeclaration complaints.
7710 (symbol_make_alias): Don't set the type of the alias, let
7711 symbol_check_alias_consistency do it as for other features.
7712 * src/symtab.h (symbol): Add new member prec_location, and
7714 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
7715 * tests/input.at (Incompatible Aliases): New.
7717 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
7719 .cvsignore fixes to accommodate gnulib changes,
7720 and the practice of naming build directories "_build".
7721 * .cvsignore: Add "_*". Sort.
7722 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
7723 * m4/.cvsignore: Add "*_gl.m4".
7725 2004-10-06 Akim Demaille <akim@epita.fr>
7727 * src/parse-gram.y (add_param): Fix the truncation of trailing
7730 2004-10-05 Akim Demaille <akim@epita.fr>
7732 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
7733 whether the reducion was empty or not. This leaves room to
7734 improve the use of YYLLOC_DEFAULT in such a case.
7735 lalr1.cc is still experimental, so changing this is acceptable.
7736 And finally, there are probably not many users who changed the
7737 handling of locations in GLR, so changing is admissible too.
7739 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
7740 empty reduction, set @$ to an empty location ending the previously
7742 Adjust uses to make sure the code is triggered on empty
7744 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
7745 expected output: empty reductions have empty locations.
7747 2004-09-29 Akim Demaille <akim@epita.fr>
7749 * data/lalr1.cc: Move towards a more standard C++ coding style
7750 for templates: Class < T > -> Class<T>.
7752 2004-09-29 Akim Demaille <akim@epita.fr>
7754 * data/lalr1.cc: Reinstall the former ctor, for sake of
7755 compatibility, but warn it will be removed.
7756 Move towards a more standard C++ coding style (i.e., type *var ->
7759 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
7761 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
7762 since it's less likely to work if NULs are involved in the future.
7764 2004-09-27 Akim Demaille <akim@epita.fr>
7766 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
7768 2004-09-27 Akim Demaille <akim@epita.fr>
7770 * data/lalr1.cc (b4_parse_param_decl_1): New.
7771 (b4_parse_param_decl): Use it to have different names between attribute
7773 (b4_cc_constructor_call): Likewise.
7775 2004-09-24 Akim Demaille <akim@epita.fr>
7777 * src/parse-gram.y (add_param): Strip the leading and trailing
7778 blanks from a formal argument declaration.
7779 (YY_LOCATION_PRINT): New.
7781 2004-09-24 Akim Demaille <akim@epita.fr>
7783 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
7786 2004-09-24 Akim Demaille <akim@epita.fr>
7788 * doc/bison.texinfo (Table of Symbols): Sort.
7790 2004-09-21 Akim Demaille <akim@epita.fr>
7792 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
7793 the useless parentheses.
7794 Suggested by Paul Eggert.
7796 2004-09-20 Akim Demaille <akim@epita.fr>
7798 Let the initial-action act on the look-ahead, and use it for the
7799 "initial push" (corresponding to an hypothetical beginning-of-file).
7800 And let lalr1.cc honor %initial-action.
7802 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
7804 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
7805 (Parser::Parser): Remove the ctor that used to initialize it.
7806 (Parser::parse): Like in the other skeletons, issue the "starting
7807 parse" message before any action.
7808 Honor %initial-action.
7809 Initialize the stacks with the lookahead.
7810 * data/yacc.c: Let $$ and @$ in %initial-action designate the
7812 Push them in the stacks.
7813 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
7815 2004-09-20 Akim Demaille <akim@epita.fr>
7817 * doc/bison.texinfo (Initial Action Decl): New.
7819 2004-09-20 Akim Demaille <akim@epita.fr>
7821 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
7822 clearer criterion to define it.
7823 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
7824 When reducing on an empty RHS, use the latest stacked location as
7826 yylloc is not always available.
7827 * data/glr.c: Likewise.
7828 Also, honor initial-actions.
7830 2004-09-20 Akim Demaille <akim@epita.fr>
7832 * data/yacc.c (YY_LOCATION_PRINT): New.
7833 Define when we know YYLTYPE's structure, i.e., when the default
7834 YYLLOC_DEFAULT is used.
7835 * data/c.m4 (b4_yysymprint_generate): Use it.
7836 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
7837 value of the result.
7838 (error_start_): Replace with...
7839 (error_range_): this location array.
7840 This allows to replace code relying on the implementation of
7841 locations by portable code.
7842 * data/yacc.c (yylerrsp): Replace with...
7843 (yyerror_range): this.
7844 Every time a token is popped, update yyerror_range[0], to have an
7845 accurate location for the error token.
7846 * data/glr.c (YY_LOCATION_PRINT): New.
7847 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
7848 deference a pointer.
7849 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
7850 report the location in %printers.
7852 * src/scan-skel.l: Instead of abort, report error messages to ease
7853 understanding skeleton scanning failures.
7855 2004-09-16 Akim Demaille <akim@epita.fr>
7857 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
7858 (iterator, const_iterator): these, to be more in the C++ spirit.
7859 Also, return reverse iterators so that when displaying the stack
7860 we display its bottom first.
7861 (Parser::stack_print_, Parser::reduce_print_): Match the messages
7863 We should probably use vector here though.
7865 2004-09-16 Akim Demaille <akim@epita.fr>
7867 Have more complete shift traces.
7869 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
7870 to report Shifts instead of ad hoc YYDPRINTF invocations,
7871 including for the error token.
7872 * data/lalr1.cc (symprint_): Output the location.
7873 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
7874 output the location within the %printer.
7875 Activate GLR tests, at least to make sure they compile properly.
7876 They still don't pass though.
7877 * tests/calc.at: Adjust expect verbose output, since now "Entering
7878 state..." is on a different line than the "Shifting" message.
7880 2004-09-08 Akim Demaille <akim@epita.fr>
7882 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
7883 Bison directive from the Bison file to the invocation of this
7884 macro, so that these directives are passed to
7885 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
7886 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
7887 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
7888 the extra Bison directives instead of the whole series.
7889 Change the grammar so that there are recoverable errors, and
7890 unrecoverable errors. Now we can have the parser give up before
7891 consuming the whole input. As a result we now can observe that
7892 the lookahead is freed when needed.
7893 Change the parser source to parse argv[1] instead of a hard coded
7895 Simplify yylex, and give a value and location to EOF.
7896 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
7897 passed directives already coded in the file.
7898 Add some tests to check the location of "error".
7899 For some tests, the C++ parser is correct, and not yacc.c.
7900 For other tests, they provide different, but unsatisfying, values,
7901 so keep the C++ value so that at least one parser is "correct"
7902 according to the test suite.
7903 (Actions after errors): Remove, this is subsumed by the
7904 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
7906 2004-09-06 Akim Demaille <akim@epita.fr>
7908 * data/lalr1.cc: Adjust the indentation of the labels.
7912 2004-09-06 Akim Demaille <akim@epita.fr>
7914 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
7915 argument, an informative message.
7916 Call YY_SYMBOL_PRINT.
7917 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
7918 * data/lalr1.cc (destruct_): Likewise.
7919 In addition, no longer depend on b4_yysymprint_generate and
7920 b4_yydestruct_generate to generate these functions, do it "by
7923 2004-09-03 Akim Demaille <akim@epita.fr>
7925 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
7926 invoked, yydestruct the lookahead.
7927 * tests/calc.at (Calculator $1): Update the expected lengths of
7928 traces: there is an added line for the discarded lookahead.
7929 * doc/bison.texinfo (Destructor Decl): Some rewording.
7930 Define "discarded" symbols.
7932 2004-09-02 Akim Demaille <akim@epita.fr>
7934 * data/lalr1.cc (translate_, destruct_): No reason to be static.
7936 2004-09-02 Akim Demaille <akim@epita.fr>
7938 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
7939 (YYDSYMPRINTF): Rename as...
7940 (YY_SYMBOL_PRINT): this.
7941 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
7943 Use it instead of direct symprint_ calls.
7944 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
7947 2004-09-02 Akim Demaille <akim@epita.fr>
7949 * data/lalr1.cc (b4_yysymprint_generate): New.
7950 (symprint_): New member function, defined when YYDEBUG.
7951 Use it consistently instead of token/nterm debugging output by
7953 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
7954 %printer calls to use cdebug_ when using lalr1.cc.
7956 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
7958 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
7959 with #ifdef YYDEBUG.
7961 2004-08-26 Akim Demaille <akim@epita.fr>
7963 * doc/bison.texinfo (Implementing Loops): Rename as...
7964 (Implementing Gotos/Loops): this.
7966 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
7968 Adjust to latest gnulib.
7969 * bootstrap (gnulib_modules): Add xalloc-die.
7970 Set LC_ALL=C so that file names sort consistently.
7971 Prefer the gnulib copies of gettext.m4, glibc21.m4,
7972 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
7973 uintmax_t.m4, ulonglong.m4.
7974 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
7975 po.m4 since we are now using _gl.m4 instead.
7977 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
7979 * src/scan-action.l: Remove. Scanning of semantic actions is
7980 handled in scan-gram.l.
7982 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
7984 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
7986 * src/location.h (struct): The file member is a uniqstr.
7987 (equal_boundaries): Use UNIQSTR_EQ for comparison.
7989 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
7991 Fix bug with non-%union parsers that have printers or destructors,
7992 which led to a Bison core dump. Reported by Peter Fales in
7993 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
7995 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
7996 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
7997 not to our own type.
7998 * src/output.c (symbol_destructors_output, symbol_printers_output):
7999 Don't assume %union.
8000 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
8001 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
8002 UNION-FLAG. All callers changed.
8003 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
8004 Use type char, not unsigned int, when declaring an array of char;
8005 this lets us remove a cast.
8006 (Printers and Destructors): Add non-%union test cases.
8008 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8010 * doc/bison.texinfo: Minor editorial changes, mostly to the new
8011 GLR writeups. E.g., avoid frenchspacing and the future tense,
8012 change "lookahead" to "look-ahead", and change "wrt" to "with
8015 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8017 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
8018 New sections, split off from the GLR Parsers section. Put the new
8019 Simple GLR Parser near the start of the GLR section, for clarity.
8020 Rewrite connective text.
8022 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
8024 * doc/bison.texinfo (Simple GLR Parsers): New section.
8026 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8028 * NEWS, TODO, doc/bison.texinfo:
8029 Use "look-ahead" instead of "lookahead", to be consistent.
8030 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
8031 while we're fixing "look-ahead".
8032 * src/conflicts.c (shift_set): Renamed from shiftset.
8033 (look_ahead_set): Renamed from lookaheadset.
8034 * src/print.c: Likewise.
8035 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
8036 name for "lookahead".

8051 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
8053 * README: Update location of patched M4 distribution.
8055 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
8057 Don't assume the C++ compiler takes the same arguments as the C compiler
8059 * configure.ac (O0CXXFLAGS): New var.
8060 * tests/atlocal.in (CXXFLAGS): Use it.
8062 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
8064 Fix some "make check" problems with C++ reported by

8068 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
8069 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

8077 * tests/calc.at, tests/actions.at: Workaround for SGI
8078 C++ compiler. (trivial change)
8080 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
8082 Spent a few hours checking out which prerequisite versions the
8083 current sources actually require. I went all the way back to
8084 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8085 a seemingly endless set of combinations of versions more recent
8086 than that. The bottom line is that the current sources require
8087 fairly recent versions of the build tools, and it'll be some work
8089 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
8090 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
8091 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
8092 Add comments explaining why those particular versions are
8095 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
8096 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
8097 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
8099 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
8100 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
8102 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8104 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
8105 0.11.5. Suggested by Bruno Haible.
8106 * bootstrap: Remove gettext version checking.
8108 * doc/bison.texinfo (Decl Summary): Also mention that %union
8109 can depend on prerequisite types. Problem reported by Tim
8112 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8114 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
8115 * README-alpha: Don't tell people not to package this.
8117 * bootstrap: Don't assume $(...) works; use `...` instead.
8118 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
8121 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
8122 put into the -d output file, and mention what to do if YYSTYPE is
8125 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8127 Undo change made earlier today: it caused autopoint to not bring
8128 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
8131 * bootstrap: Check that gettext version matches what's in
8132 configure.ac. Warn users to ignore robots.txt ERROR 404.
8133 * bootstrap: Undo today's earlier change (logged below).
8134 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
8136 The gettext version checking is causing more trouble than it's
8137 curing; remove it. Problem reported by Paul Hilfinger.
8139 * bootstrap: Issue a warning that one can expect a message
8140 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
8141 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
8143 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
8145 Ensure that the C++ compiler used for testing actually works on a
8146 simple test program; if not, skip the C++-related tests. Problem
8147 reported by Vin Shelton in:
8148 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
8150 * m4/cxx.m4: New file.
8151 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
8152 * tests/atlocal.in (BISON_CXX_WORKS): Add.
8153 * tests/local.at (AT_COMPILE_CXX): Use it.
8155 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
8157 * data/glr.c (yylloc): Output this macro even if locations are not
8158 being generated, as the GLR parser needs it even in that case.
8159 Problem reported by Troy A. Johnson
8160 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
8162 * configure.ac (AC_INIT): Update to 1.875e.
8164 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
8166 * NEWS: Version 1.875d.
8167 * configure.ac (AC_INIT): Likewise.
8168 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
8170 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
8171 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
8172 lalr1.cc runs afoul of the first, and the last two are no longer
8173 supported by GCC 3.4.0.
8174 * README: Mention GNU m4 1.4 or later; mention m4 patches.
8175 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
8177 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
8179 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
8180 unsigned int, for compatibility with latest gnulib hash module.
8181 * src/state.c (state_hash, state_hasher): Likewise.
8182 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.

8201 Fix typo by replacing $1 with $option.
8202 Remove more 'intl'-related files.
8203 Don't DEFUN AM_INTL_SUBDIR twice.
8205 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,

8213 * src/.cvsignore: Add *.output.
8215 * src/parse-gram.y: Put copyright notice inside %{ %} so it
8216 gets copied to the output file.
8218 2004-04-28 Paul Eggert <eggert@twinsun.com>
8220 Get files from the gnulib and po repositories, instead of relying
8221 on them being in our CVS. Upgrade to latest versions of gnulib
8224 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
8225 * bootstrap: Bootstrap from gnulib and po repositories.
8226 Much of this code was stolen from GNU diff and GNU tar's bootstrap.

8233 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
8235 (AC_ISC_POSIX): Remove; we no longer support this
8236 ancient OS, as it gets in the way of latest Autoconf & gnulib.
8237 (AC_HEADER_STDC): Remove: we now assume C89 or better.
8238 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
8239 Do not check for C89 headers, except for locale.h which is used
8240 by the Yacc library and must port to K&R hosts.
8241 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
8242 Do not check for C89 functions, except for setlocale which is
8243 used by the Yacc library.

8254 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
8255 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):

8259 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
8260 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
8262 * src/files.c: Include gnulib's xstrndup.h.
8264 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
8265 (REALLOC): Use xnrealloc, for likewise.
8266 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.

8291 Remove, as these files are now generated automatically
8292 by bootstrap or automake.

8318 support it. (The latest stable gzip doesn't.)
8320 2004-04-27 Paul Eggert <eggert@twinsun.com>
8322 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
8323 case, as stos_ is now used by destructors due to the 2004-02-09
8326 Remove more K&R C support.

8348 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
8350 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
8351 so that this include file can stand alone.
8352 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
8353 does this now. Include subpipe.h first after config.h, to
8354 test whether it can stand alone.
8356 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
8357 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
8360 * tests/synclines.at (%union synch line): Put a dummy member in
8361 the union, because empty unions aren't allowed in C. Caught
8364 2004-04-13 Jim Meyering <jim@meyering.net>
8366 * src/conflicts.c (conflicts_print): Correct format string typo:

8427 Use expected_sr_conflicts in place of expected_conflicts.
8428 Warn if expected_rr_conflicts used in non-GLR parser.
8430 * doc/bison.texinfo: Add documentation for %expect-rr.
8432 2004-03-08 Paul Eggert <eggert@gnu.org>

8449 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
8450 compilers. This fixes a problem with Intel's C++ compiler being
8451 chatty, reported by Guido Trentalancia in
8452 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.

8466 error_start_ when erroneous token are discarded.
8467 (Parser::parse) <yyerrlab1>: Compute the location of the error
8468 token so that it covers all the discarded tokens.
8469 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
8470 it can be called with `%skeleton "lalr1.cc"', and do that.
8472 2004-02-02 Paul Eggert <eggert@twinsun.com>
8474 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
8475 $(top_srcdir)/lib and ../lib. This fixes a bug reported
8476 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
8477 There's no need to mention top_builddir since Automake does that
8479 (INCLUDES): Remove, as Automake says it's obsolescent.
8480 Contents migrated into AM_CPPFLAGS as described above.
8481 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
8483 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>

8494 2003-12-23 Paul Eggert <eggert@twinsun.com>
8496 * config/depcomp, config/install-sh: Sync with Automake 1.8.
8497 * src/output.c (output_skeleton): Rename local var.
8498 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
8499 Bison tokens, as this runs afoul of the 2003-10-07 change that
8500 disallowed NUL bytes in character constants or string literals.
8502 * tests/local.at: Require Autoconf 2.59's Autotest.
8503 * tests/testsuite.at: Don't include local.at, since we now assume
8504 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
8506 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
8507 multiple inclusion warnings.
8509 2003-12-02 Akim Demaille <akim@epita.fr>

8525 literals, unfortunately.
8526 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
8527 Complain about NUL bytes in character constants or string literals.
8529 2003-10-05 Paul Eggert <eggert@twinsun.com>
8531 * NEWS: Don't document %no-default-prec, as it's still
8533 * doc/bison.texinfo: Document %no-default-prec only if
8534 the defaultprec flag is set. Normally it's not.
8536 2003-10-04 Paul Eggert <eggert@twinsun.com>
8538 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
8539 non-modifiable lvalue, instead of a modifiable one.
8540 * doc/bison.texinfo (Actions): Document that $$ can
8541 be assigned to. Do not claim that $$ and $N are
8542 array element references: user code should not rely on this.
8544 2003-10-01 Paul Eggert <eggert@twinsun.com>
8546 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

8557 * src/print_graph.c (print_graph): Adjust.
8559 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
8560 and Paul Eggert <eggert@twinsun.com>
8562 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
8563 Table of Symbols): Document %default-prec.
8564 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.

8595 2003-08-25 Akim Demaille <akim@epita.fr>
8597 * config/announce-gen, Makefile.cfg: New.
8598 * Makefile.am: Adjust.
8599 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
8600 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
8602 2003-08-25 Akim Demaille <akim@epita.fr>
8604 When reducing initial empty rules, Bison parser read an initial
8605 location that is not defined. This results in garbage, and that
8606 affects Bison's own parser. Therefore we need (i) to extend Bison
8607 to support a means to initialize this location, and (ii) to use
8608 this CVS Bison to fix CVS Bison's parser.
8610 * src/reader.h, reader.c (epilogue_augment): Remove, replace
8612 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
8613 * src/parse-gram.y: Adjust.
8614 (%initial-action): New.
8615 (%error-verbose): Since we require CVS Bison, there is no reason
8617 * src/scan-gram.l: Adjust.
8618 * src/Makefile.am (YACC): New, to make sure we use our own parser.
8619 * data/yacc.c (yyparse): Use b4_initial_action.
8621 2003-08-25 Akim Demaille <akim@epita.fr>
8623 * doc/bison.texinfo: Don't promote stdout for error messages.
8625 2003-08-25 Akim Demaille <akim@epita.fr>
8627 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
8628 From Alexandre Duret-Lutz.
8630 2003-08-25 Akim Demaille <akim@epita.fr>
8634 2003-08-25 Akim Demaille <akim@epita.fr>
8636 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
8639 2003-08-25 Akim Demaille <akim@epita.fr>
8641 * data/lalr1.cc (Parser::reduce_print_): New.
8644 2003-08-25 Akim Demaille <akim@epita.fr>
8646 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
8647 error recovery loops. This patch is based on
8648 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
8649 Also, augment the similarity between lalr1.cc and yacc.c.
8650 Note: the locations of error recovery rules are not correct yet.
8652 * data/lalr1.cc: Comment changes to augment the similarity between
8653 lalr1.cc and yacc.c.
8654 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
8655 (yyerrlab1): Remove, but where it used to be (now the bottom part of
8656 yyerrlab), when hitting EOF, pop the whole stack here instead of
8657 merely falling thru the default error handling mechanism.
8658 (yyerrorlab): New label, with the old contents of YYERROR,
8659 plus the following change: pop the stack of rhs corresponding
8660 to the production that invoked YYERROR. That is how Yacc
8661 behaves (required by POSIX).
8662 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
8665 2003-08-25 Akim Demaille <akim@epita.fr>
8667 Tune local.at so that people can "autom4te -l autotest calc.at -o
8668 calc" for instance, to extract a sub test suite.
8670 * tests/testsuite.at: Move the initialization, Autotest version
8671 requirement, and AT_TESTED invocation into...
8672 * tests/local.at: here.
8673 * tests/testsuite.at: Include it for compatibility with Autoconf
8675 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
8678 2003-08-04 Paul Eggert <eggert@twinsun.com>
8680 Rework code slightly to avoid gcc -Wtraditional warnings.
8681 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
8682 The returned value is now stored in *YY0. All callers changed.
8683 * src/output.c (merge_output): Adjust to the above change.
8685 2003-07-26 Paul Eggert <eggert@twinsun.com>
8687 * data/glr.c (YYASSERT): New macro.
8688 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
8689 yyresolveStates, yyprocessOneStack):
8690 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
8691 Derived from a suggestion by Frank Heckenbach.
8693 2003-07-25 Paul Eggert <eggert@twinsun.com>
8695 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
8696 for portability to K&R C (after ansi2knr, presumably). See
8697 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
8698 by Frank Heckenbach, though I have omitted the structure-initialization
8699 part of his glr-knr.diff patch since I recall that the Portable
8700 C Compiler didn't require that change.
8702 Let the user specify how to allocate and free memory.
8703 Derived from a suggestion by Frank Heckenbach in
8704 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
8705 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
8706 All uses of free, malloc, realloc changed to use these macros,
8707 and unnecessary casts removed.
8708 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
8710 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
8712 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
8713 use s.empty() rather than s == "" to test for empty string; see
8714 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
8717 2003-06-25 Akim Demaille <akim@epita.fr>
8719 * config/depcomp, config/install-sh: Update from masters.
8721 2003-06-20 Paul Eggert <eggert@twinsun.com>
8723 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
8724 and return properly parenthesized result.
8725 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
8726 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8727 Remove unnecessary parentheses from uses.
8728 * doc/bison.texinfo (Location Default Action): Describe the
8729 conventions for parentheses.
8731 2003-06-19 Paul Eggert <eggert@twinsun.com>
8733 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
8734 yyreportTree): Do not assume that size_t is the same width as int,
8735 when printing sizes. Print sizes using an unsigned format.
8736 Problem reported by Frank Heckenbach in
8737 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
8739 Port to Forte Developer 7 C compiler.
8740 * data/glr.c (struct YYLTYPE): If locations are not being used,
8741 declare a single dummy member, as empty structs do not conform
8743 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
8744 the Forte Developer 7 C compiler complains that end-of-loop
8745 code is not reached.
8747 2003-06-17 Paul Eggert <eggert@twinsun.com>
8749 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
8750 avoid warnings from picky compilers about redefinition of PARAMS.
8752 2003-06-17 Paul Eggert <eggert@twinsun.com>
8756 * NEWS: Document 1.875b.
8758 * lib/bbitset.h: Do not include config.h; that's the includer's job.
8759 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
8760 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
8761 Don't use 'index' in comments, as it's a builtin fn on some hosts.
8762 * lib/bitset_stats.c: Include gettext.h unconditionally, as
8763 per recent gettext manual's suggestion.
8764 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
8765 Use prototypes, not old-style definitions.
8766 * lib/lbitset.c (lbitset_unused_clear): Likewise.
8767 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
8768 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,

8783 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
8784 * lib/vbitset.c, lib/vbitset.h: New files.
8785 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
8786 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
8789 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
8790 `How Can I Reset @code{yyparse}', since texinfo does not allow
8791 arbitrary @ in node names.
8793 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
8794 shouldn't be needed according to the gettext 0.12.1 documentation
8795 but which seem to be needed anyway: codeset.m4 glibc21.m4
8796 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
8797 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

8809 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
8810 (MOSTLYCLEANFILES): New var.
8811 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
8812 (stdbool.h): New rule.

8818 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
8819 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
8820 the tests right now.
8821 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
8822 yyerror are declared before use; C99 requires this.
8824 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8826 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
8828 (yyrecoverSyntaxError): Correct the logic for setting and testing
8830 Correct comment on handling EOF.
8831 Allow states with only a default reduction, rather than failing
8832 (I can't quite reconstruct why these were not allowed before).
8834 Fixes to avoid problem that $-N rules in GLR parsers can cause
8835 buffer overruns, corrupting state.
8837 * src/output.c (prepare_rules): Output max_left_semantic_context
8839 * src/reader.h (max_left_semantic_context): New variable declaration.
8840 * src/scan-gram.l (max_left_semantic_context): Define.

8844 (yyresolveAction): Ditto.
8846 Fixes to problems with location handling in GLR parsers reported by
8847 Frank Heckenbach (2003/06/05).
8849 * data/glr.c (YYLTYPE): Make trivial if locations not used.
8850 (YYRHSLOC): Add parentheses, and define only if locations used.
8851 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
8853 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
8854 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
8856 * tests/cxx-type.at: Exercise location information; update tests
8857 to differentiate output with and without locations.
8858 Remove forward declarations of yylex and yyerror---caused errors
8859 because default YYLTYPE not yet defined.
8860 Change semantic actions to compute strings, rather than printing
8861 them directly (to test proper passing of semantics values). Change
8862 output to prefix notation and update test data and expected results.
8863 (yylex): Track locations.
8864 (stmtMerge): Return value rather than printing, and include arguments
8867 2003-06-03 Paul Eggert <eggert@twinsun.com>
8869 Avoid warnings generated by GCC 2.95.4 when Bison is
8870 configured with --enable-gcc-warnings.

8875 yy::Slice::operator[] (unsigned),
8876 yy::Slice::operator[] (unsigned) const):
8877 Rename local vars to avoid warnings.
8878 * tests/glr-regression.at (Improper handling of embedded actions
8879 and $-N in GLR parsers): Remove unused local variable from yylex.
8880 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
8881 (void) as arg when not pure, since we now assume C89 when building
8882 Bison. Pacify GCC by using parameter.
8884 2003-06-02 Paul Eggert <eggert@twinsun.com>
8886 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
8887 yy::Location::lines, yy::Location::columns): Rename arguments
8888 to avoid shadowing; this removes a warning generated by GCC 3.3.
8890 2003-06-01 Paul Eggert <eggert@twinsun.com>
8892 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
8893 to g++, as GCC 3.3 complains if you do it.
8894 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
8895 everything that WARNING_CFLAGS has, except omit warnings
8896 not suitable for C++.
8897 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
8898 * tests/atlocal.in (CXXFLAGS): New var.
8899 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
8901 Fix a GLR parser bug I reported in February; see
8902 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
8903 The problem was that GLR parsers did not conform to the C standard,
8904 because actions like { $1 = $2 + $3; } expanded to expressions
8905 that invoked YYFILL in separate subexpressions, and YYFILL assigned
8906 to a local variable. The C standard says that expressions
8907 like (var = f ()) + (var = f ()) have undefined behavior.
8908 Another problem was that GCC sometimes issues warnings that
8909 yyfill and its parameters are unused.
8911 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
8913 (yyfill): New function.
8915 (yyuserAction): Change type of yynormal to bool, so that it matches
8916 the new yyfill signature. Mark it as possibly unused.
8919 Follow up on a bug I reported in February, where a Bison-generated
8920 parser can loop. Provide a test case and a fix for yacc.c. I
8921 don't have a fix for lalr1.cc or for glr.c, unfortunately.
8922 The original bug report is in:
8923 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
8925 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
8926 macro's size was becoming unwieldy.
8927 (yyerrlab): Do not discard an empty lookahead symbol, as this
8928 might destroy garbage.
8929 (yyerrorlab): New label, with the old contents of YYERROR,
8930 plus the following change: pop the stack of rhs corresponding
8931 to the production that invoked YYERROR. That is how Yacc
8932 behaves, and POSIX requires this behavior.
8933 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
8934 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
8935 Define 'alarm' to do nothing if unistd.h is not available.
8936 Add a new rule "exp: '-' error;" to test the above change to
8937 data/yacc.c. Use 'alarm' to abort any test taking longer than
8938 10 seconds, as it's probably looping.
8939 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
8940 Also, the new yacc.c generates two fewer diagnostics for an
8943 2003-05-24 Paul Eggert <eggert@twinsun.com>
8945 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
8946 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
8947 This fixes a problem reported by John Bowman when the Compaq/HP
8948 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
8950 * data/yacc.c (union yyalloc): Likewise.
8951 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
8953 Switch from 'int' to 'bool' where that makes sense.

8979 lbitset_xor_cmp): Likewise.
8980 * lib/bbitset.h: Include <stdbool.h>.

9016 2003-05-14 Paul Eggert <eggert@twinsun.com>
9018 * src/parse-gram.y (rules_or_grammar_declaration): Require a
9019 semicolon after a grammar declaration, in the interest of possible
9020 future changes to the Bison input language.
9021 Do not allow a stray semicolon at the start of the grammar.
9022 (rhses.1): Allow one or more semicolons after any rule, including
9023 just before "|" as required by POSIX.
9024 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
9027 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
9029 %parse-param support for lalr1.cc.
9031 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,

9037 (yy::b4_parser_class_name): Declare instance variables to

9040 with a member of yy::b4_parser_class_name. Adjust C++ code
9041 to handle %parse-param. Enable %parse-param test in C++.
9043 2003-05-12 Paul Eggert <eggert@twinsun.com>
9045 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
9046 English a bit. Fix fclose typo. Change "const char" to "char
9047 const", and use ANSI C rather than K&R for "main". Suggest
9048 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
9049 and suggest yy_switch_to_buffer.
9051 2003-05-05 Paul Eggert <eggert@twinsun.com>
9053 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
9054 C89. This avoids a diagnostic on compilers that define __STDC__
9055 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in

9060 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
9061 Do not overrun array bounds.
9062 This should fix a bug reported today by Olatunji Oluwabukunmi in
9063 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
9065 2003-04-29 Akim Demaille <akim@epita.fr>
9067 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
9068 * src/getargs.c, src/getargs.h: here, as bool, not int.
9069 (nondeterministic_parser): New.
9070 * src/parse-gram.y, src/scan-gram.l: Support
9071 %nondeterministic-parser.
9072 * src/output.c (prepare): Use nondeterministic_parser instead
9073 of glr_parser where appropriate.
9074 * src/tables.c (conflict_row, action_row, save_row)
9075 (token_actions, token_actions, pack_vector): Ditto.
9077 2003-04-29 Akim Demaille <akim@epita.fr>
9079 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
9081 2003-04-29 Akim Demaille <akim@epita.fr>
9083 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
9084 with %pure-parser and %locations to exercise the patch from Yakov
9087 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
9089 * data/yacc.c: (b4_lex_param): Corrected for the case where
9090 %lex-param is provided and %pure-parser isn't.
9092 2003-04-27 Paul Eggert <eggert@twinsun.com>
9094 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
9095 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
9096 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
9097 if it is not defined.
9098 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
9100 2003-04-26 Paul Eggert <eggert@twinsun.com>
9102 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
9103 Declare to be of type suitable for the ninf value itself, not of
9104 type suitable for the corresponding table, since the latter might
9105 be unsigned but the ninf value might be negative. This fixes a
9106 bug reported by Alexandre Duret-Lutz in
9107 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
9109 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
9110 invokes it. We shouldn't invoke it twice because it will attempt
9111 to put error.o in the archive twice. This fixes a glitch reported
9112 by Martin Mokrejs in
9113 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9115 2003-04-21 Paul Eggert <eggert@twinsun.com>
9117 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
9120 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
9122 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
9123 Fix obvious typo that results in uncompilable GLR parsers
9124 when both %pure-parser and %locations are used. (trivial change)
9126 2003-04-17 Paul Eggert <eggert@twinsun.com>
9128 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
9129 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
9130 Do not insert the expected token via unput, as this runs afoul
9131 of a POSIX-compatibility bug in flex 2.5.31.
9132 All uses changed to BEGIN the parent state,
9133 since we no longer insert the expected token via unput.
9134 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
9135 that is no longer emitted after the above change.
9137 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
9138 the first one. This change is from Paul Hilfinger, and it fixes
9139 regression reported by Werner Lemberg in
9140 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
9142 (resolve_sr_conflict): Don't invoke state_errs_set
9143 unless one or more tokens have been explicitly made errors.
9144 Otherwise, the above change causes Bison to abort.
9146 * tests/existing.at (GNU pic Grammar): New test case, taken from
9149 2003-03-31 Akim Demaille <akim@epita.fr>
9151 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
9153 2003-03-31 Akim Demaille <akim@epita.fr>
9155 * src/output.c (prepare_symbols): Avoid trailing spaces in the
9158 2003-03-31 Akim Demaille <akim@epita.fr>
9160 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
9161 From Paul Hilfinger.
9163 2003-03-29 Akim Demaille <akim@epita.fr>
9165 * m4/error.m4: Do not put under dynamic conditions some code which
9166 expansion is under static control.
9168 2003-03-29 Akim Demaille <akim@epita.fr>
9170 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
9172 2003-03-29 Akim Demaille <akim@epita.fr>
9174 * doc/bison.texinfo (Strings are Destroyed): New.
9176 2003-03-13 Paul Eggert <eggert@twinsun.com>
9178 * .cvsignore: Add configure.lineno.
9179 * src/.cvsignore: Add yacc.
9180 * tests/.cvsignore: Add testsuite.log.
9181 * doc/fdl.texi: Sync with latest FSF version.
9183 2003-03-12 Paul Eggert <eggert@twinsun.com>
9185 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
9186 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
9187 cursor, instead of leaving it undefined. This fixes a bug
9188 reported by Tim Van Holder in
9189 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
9190 * tests/input.at (Torturing the Scanner): Test the scanner on
9191 an empty input file, which was Tim Van Holder's test case.
9193 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
9194 <sys/resource.h> can be included, include sys/time.h and
9195 sys/times.h first, if available. This works around the SunOS
9196 4.1.4 porting bug reported by Bruce Becker in
9197 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
9199 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
9200 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
9203 Merge changes from gnulib. This was prompted because the CVS
9204 snapshot didn't build on Solaris 7 due to strnlen problems.
9206 These changes need to be merged back into gnulib:
9207 * lib/hash.c: Include <stdbool.h> unconditionally.
9208 * m4/onceonly.m4 (m4_quote): New macro.
9209 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
9210 Quote AC_FOREACH variable-expansions properly.
9211 The 2003-01-03 obstack.h change also needs merging.
9212 {end of changes requiring merging}
9214 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
9215 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
9216 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,

9218 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
9219 New files, imported from gnulib.
9220 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
9223 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
9224 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current

9232 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
9233 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
9234 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
9235 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
9236 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
9237 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
9238 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
9239 (jm_PREREQ_ARGMATCH): Remove.
9240 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
9241 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
9243 * src/system.h: Include <stdbool.h> unconditionally.
9245 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
9246 assuming at least C89 in the bitset code for some time now.
9248 2003-03-03 Akim Demaille <akim@epita.fr>
9252 2003-03-02 Akim Demaille <akim@epita.fr>
9254 * doc/bison.texinfo (Table of Symbols): Reactivate the
9255 documentation for %lex-param, and %parse-param.
9257 2003-03-02 Akim Demaille <akim@epita.fr>
9259 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
9260 generate verbose error messages.
9261 Use the number of tokens as an upper bound in yytname, as it
9262 cannot be a non terminal.
9264 2003-03-02 Akim Demaille <akim@epita.fr>
9266 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
9269 2003-03-02 Akim Demaille <akim@epita.fr>
9271 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
9272 Use them to exercise yycheck overrun.
9273 Based on Andrew Suffield's grammar.
9275 2003-03-02 Akim Demaille <akim@epita.fr>
9277 Create tests/local.at for Bison generic testing macros.
9279 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
9280 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
9282 * tests/calc.at (AT_CHECK_CALC): Adjust.
9283 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
9284 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
9285 * tests/local.at: here.
9286 (AT_COMPILE_CXX): Tags the tests using it as c++.
9287 Ignore the test if CXX is not functional.
9289 2003-03-01 Paul Eggert <eggert@twinsun.com>
9291 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
9292 not loc->end, since loc->end might contain garbage and this leads
9293 to undefined behavior on some platforms.
9294 (id_loc, token_start): Use (IF_LINTed) initial values that do not
9295 depend on *loc, so that the reader doesn't give the the false
9296 impression that *loc is initialized.
9297 (<INITIAL>"%%"): Do not bother setting code_start, since its value
9298 does not survive the return.
9300 2003-03-01 Akim Demaille <akim@epita.fr>
9302 * src/scan-gram.l (code_start): Always initialize it when entering
9303 into yylex, as SC_EPILOGUE is activated *before* the corresponding
9304 yylex invocation. An alternative would be making it static, but
9305 then it starts with the second %%'s beginning, instead of its end.
9307 2003-02-28 Paul Eggert <eggert@twinsun.com>
9309 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
9310 around a UnixWare 7.1.1 porting bug reported by John Hughes in
9311 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
9313 2003-02-26 Paul Eggert <eggert@twinsun.com>
9315 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
9316 Remove Sequent/Pyramid discussion (nobody uses them any more).
9317 Merge VMS and MS-DOS discussion; these ports may well be dead
9318 but let's keep mentioning them for now. Put <> around email
9319 addresses. Add copyright notice.
9321 2003-02-24 Paul Eggert <eggert@twinsun.com>
9323 * data/glr.c (yy_reduce_print): yylineno -> yylno,
9324 to avoid collision with flex use of yylineno.
9325 Problem reported by Bruce Lilly in
9326 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

9335 change integer types.
9336 Suggested by Paul Eggert.
9338 2003-02-21 Akim Demaille <akim@epita.fr>
9340 * doc/bison.texinfo: Use "location" consistently to refer to @n,
9341 to avoid confusions with lalr1.cc's notion of Position.
9342 Suggested by Paul Eggert.
9344 2003-02-20 Akim Demaille <akim@epita.fr>
9346 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
9347 before initial_columns.
9348 (location.hh): Use consistent variable names when defining the
9350 Use "last" so that we subtract from Positions, not from unsigned.
9352 2003-02-20 Akim Demaille <akim@epita.fr>
9354 * data/lalr1.cc (position.hh): New subfile, including the extended
9355 and Doxygen'ed documentation of class Position.
9356 (location.hh): Use it.
9357 Document a` la Doxygen.
9358 With the help of Benoit Perrot.
9360 2003-02-20 Akim Demaille <akim@epita.fr>
9362 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define

9367 Don't use the location in yy::Parser::error_ and
9368 yy::Parser::print_ when not %locations.
9369 Activate more lalr1.cc tests.
9371 2003-02-19 Akim Demaille <akim@epita.fr>
9373 * data/lalr1.cc: When displaying a line number, be sure to make it
9376 2003-02-19 Akim Demaille <akim@epita.fr>
9378 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
9380 (YYABORT, YYACCEPT, YYERROR): New.
9381 * tests/calc.at: Renable the lalr1.cc test.
9383 2003-02-19 Akim Demaille <akim@epita.fr>
9385 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
9386 error recovery, mixing with/without pops and discarding of the
9389 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
9391 2003-02-17 Paul Eggert <eggert@twinsun.com>
9393 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
9394 * tests/testsuite.at (AT_COMPILE): Use them.
9395 This fixes the testsuite problem reported by Robert Lentz in
9396 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
9398 2003-02-12 Paul Eggert <eggert@twinsun.com>

9539 to rhs array when in GLR mode.
9540 Define YYFILL to use in user-defined actions to fill semantic array
9542 Remove dummy use of yystack, as there is now a guaranteed use.
9543 (yydoAction): Modify to allow incremental move of semantic values
9544 to rhs array when in GLR mode.
9545 (yyresolveAction): Ditto.
9546 (yyglrShiftDefer): Update comment.
9547 (yyresolveStates): Use X == NULL for pointers, not !X.
9548 (yyglrReduce): Ditto.
9551 * tests/glr-regr1.at: Rename to ...
9552 * tests/glr-regression.at: Add new regression test for the problems
9553 described above (adapted from S. Eken).
9554 Update copyright notice.
9555 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
9556 * tests/Makefile.am: Ditto.
9558 2003-01-28 Paul Eggert <eggert@twinsun.com>
9560 * data/lalr1.cc: Do not use @output_header_name@ unless
9561 b4_defines_flag is set. This fixes two bugs reported by
9563 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
9564 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
9566 2003-01-21 Paul Eggert <eggert@twinsun.com>
9568 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
9569 we don't need to worry about yyerrlab1 being reported as an
9570 "unused label" by non-GCC C compilers. The downside is that if
9571 locations are used then a couple of statements are duplicated each
9572 time YYERROR is invoked, but the upside is that the warnings
9574 (yyerrlab1): Move code to YERROR.
9575 (yyerrlab2): Remove. Change uses back to yyerrlab1.
9576 This reverts some of the 2002-12-27 change.
9578 2003-01-17 Paul Eggert <eggert@twinsun.com>
9580 * src/output.c (symbol_printers_output): Fix typo that led
9581 to core dump. Problem reported by Antonio Rus in
9582 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
9584 2003-01-13 Akim Demaille <akim@epita.fr>,
9585 Quoc Peyrot <chojin@lrde.epita.fr>,
9586 Robert Anisko <anisko_r@lrde.epita.fr>
9588 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
9589 when the stacks contain one element, as the loop would otherwise
9590 free the last state, and then use the top state (the one we just
9591 popped). This means that the initial elements will not be freed
9592 explicitly, as is the case in yacc.c; it is not a problem, as
9593 these elements have fake values.
9595 2003-01-11 Paul Eggert <eggert@twinsun.com>
9597 * NEWS: %expect-violations are now just warnings, reverting
9598 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
9599 bootstrapping problem reported by Matthias Klose; see
9600 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
9601 * src/conflicts.c (conflicts_print): Likewise.
9602 * tests/conflicts.at (%expect not enough, %expect too much,
9603 %expect with reduce conflicts): Likewise.
9604 * doc/bison.texinfo (Expect Decl): Document this. Also mention
9605 that the warning is enabled if the number of conflicts changes
9606 (not necessarily increases).
9608 * src/getargs.c (version): Update copyright year.
9610 2003-01-09 Akim Demaille <akim@epita.fr>
9612 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
9614 2003-01-08 Paul Eggert <eggert@twinsun.com>
9616 * Makefile.maint (WGETFLAGS):
9617 New macro, containing "-C off" to disable proxy caches.
9618 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
9619 (rel-check): Use $(WGET) instead of wget.
9621 2003-01-06 Paul Eggert <eggert@twinsun.com>
9623 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
9624 the GLR paper of Scott, Johnstone and Hussain.
9626 2003-01-04 Paul Eggert <eggert@twinsun.com>
9628 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
9629 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
9630 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
9631 (EXTRA_LIBRARIES): New var, for liby.a.
9632 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
9633 (EXTRA_SCRIPTS): New var, for yacc.
9635 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
9636 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
9637 Problem reported by Nelson H. F. Beebe.
9639 2003-01-03 Paul Eggert <eggert@twinsun.com>
9641 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
9642 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
9643 when compiling Bison 1.875's `bitset bset = obstack_alloc
9644 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
9646 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
9647 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
9648 grow to a huge size with typical invocation.
9650 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
9651 Use the pattern recommended by Autoconf 2.57, except also protect
9652 against double-definition.
9653 * src/system.h: Likewise.
9654 Portability issues reported by Nelson H. F. Beebe.
9656 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
9657 All uses changed. Provide a definition in both C and C++.
9658 (yytrue, yyfalse): Define even if defined (__cplusplus).
9660 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
9661 Reported by Nelson H. F. Beebe.
9663 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
9665 2003-01-02 Paul Eggert <eggert@twinsun.com>
9667 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
9668 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
9669 Bug reported by Nelson H. F. Beebe.
9671 2003-01-01 Paul Eggert <eggert@twinsun.com>
9675 2002-12-30 Paul Eggert <eggert@twinsun.com>
9677 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
9679 (<INITIAL>","): Here. This causes stray "," to be treated
9682 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
9683 last brace in braced code when not in Yacc mode, for compatibility
9684 with Bison 1.35. This resurrects the 2001-12-15 patch to
9687 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
9688 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
9690 2002-12-28 Paul Eggert <eggert@twinsun.com>
9692 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
9693 that of SYM's type. This fixes Debian bug 168069, reported by
9696 2002-12-28 Paul Eggert <eggert@twinsun.com>
9700 Switch back to the Yacc style of conflict reports, undoing some
9701 of the 2002-07-30 change.
9702 * doc/bison.texinfo (Understanding): Use Yacc style for
9703 conflict reports. Also, use new way of locating rules.
9704 * src/conflicts.c (conflict_report):
9705 Renamed from conflict_report_yacc, removing the old
9706 'conflict_report'. Translate the entire conflict report at once,
9707 so that we don't assume that "," has the same interpretation in
9709 (conflicts_output): Use Yacc-style conflict report for each state,
9710 instead of our more-complicated style.
9711 (conflicts_print): Use Yacc-style conflict report, except print
9712 the input file name when not emulating Yacc.
9713 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
9714 Conflicted Reduction, %expect not enough, %expect too much,
9715 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
9716 * tests/existing.at (GNU Cim Grammar): Likewise.
9717 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
9719 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
9720 fatal): Don't invoke fflush; it's not needed and it might even be
9721 harmful for stdout, as stdout might not be open.
9722 * src/reduce.c (reduce_print): Likewise.
9724 2002-12-27 Paul Eggert <eggert@twinsun.com>
9726 Fix a bug where error locations were not being recorded correctly.
9727 This problem was originally reported by Paul Hilfinger in
9728 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
9730 * data/yacc.c (yyparse): New local var yylerrsp, to record the
9731 top of the location stack's error locations.
9732 (yyerrlab): Set it. When discarding a token, push its location
9733 onto yylerrsp so that we don't lose track of the error's end.
9734 (yyerrlab1): Now is only the target of YYERROR, so that we can
9735 properly record the location of the action that failed. For GCC
9736 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
9737 GCC warning about yyerrlab1 being unused if YYERROR is unused.
9738 (yyerrlab2): New label, which yyerrlab now falls through to.
9739 Compute the error's location by applying YYLLOC_DEFAULT to
9740 the locations of all the symbols that went into the error.
9741 * doc/bison.texinfo (Location Default Action): Mention that
9742 YYLLOC_DEFAULT is also invoked for syntax errors.
9743 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9744 Error locations include the locations of all the tokens that were
9745 discarded, not just the last token.
9747 2002-12-26 Paul Eggert <eggert@twinsun.com>
9749 * src/files.c: Include quote.h.
9750 (compute_output_file_names): Warn if we detect conflicting
9751 outputs to the same file. This should catch the misunderstanding
9752 exemplified by Debian Bug 165349, reported by Bruce Stephens..
9754 * src/conflicts.c (conflicts_print): If the user specifies
9755 "%expect N", report an error if there are any reduce/reduce
9756 conflicts. This is what the manual says should happen.
9757 This fixes Debian bug 130890, reported by Anthony DeRobertis.
9758 * tests/conflicts.at (%expect with reduce conflicts): New test.
9760 Don't use m4_include on relative file names, as it doesn't work as
9761 desired if there happens to be a file with that name under ".".
9763 * m4sugar/version.m4: Remove; it was included but it wasn't used.
9764 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
9765 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
9766 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
9767 * src/output.c (output_skeleton): Use full path names when
9768 specifying a file to include; don't rely on include path, as
9769 it's unreliable when the working file contains a file with
9772 2002-12-25 Paul Eggert <eggert@twinsun.com>
9774 Remove obsolete references to bison.simple and bison.hairy.
9775 Problem mentioned by Aubin Mahe in
9776 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
9777 * data/glr.c: Comment fix.
9778 * doc/bison.1: Remove references. Also, mention "yacc".
9780 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
9783 * src/parse-gram.y (declaration): Use enum "report_states" rather
9784 than its numeric value 1.
9786 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
9787 opening a new one. This fixes Debian bug 165349, reported by
9790 2002-12-24 Paul Eggert <eggert@twinsun.com>
9794 * Makefile.maint (cvs-update): Don't assume that the shell
9795 supports $(...), as Solaris sh doesn't.
9797 * src/parse-gram.y (lloc_default): Remove test for empty
9798 nonterminals at the end, since it didn't change the result.
9800 2002-12-24 Paul Eggert <eggert@twinsun.com>
9802 If the user does not define YYSTYPE as a macro, Bison now declares it
9803 using typedef instead of defining it as a macro. POSIX requires this.
9804 For consistency, YYLTYPE is also declared instead of defined.
9806 %union directives can now have a tag before the `{', e.g., the
9807 directive `%union foo {...}' now generates the C code
9808 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
9809 The default union tag is `YYSTYPE', for compatibility with Solaris 9
9810 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
9811 instead of `yyltype'.
9813 `yystype' and `yyltype' are now obsolescent macros instead of being
9814 typedefs or tags; they are no longer documented and will be
9815 withdrawn in a future release.
9817 * data/glr.c (b4_location_type): Remove.
9818 (YYSTYPE): Renamed from yystype.
9819 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
9820 (struct YYLTYPE): Renamed from struct yyltype.
9821 (YYLTYPE): Renamed from yyltype.
9822 (yyltype, yystype): New (and obsolescent) macros,
9823 for backward compatibility.
9824 * data/yacc.c: Likewise.
9826 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
9827 does not specify a union tag. This is for compatibility with
9830 * src/parse-gram.y (add_param): 2nd arg is now char * not char
9831 const *, since it is now modified by stripping surrounding { }.
9832 (current_braced_code): Remove.
9833 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
9834 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
9835 trailing " {...}". Now of type <chars>.
9836 (grammar_declaration): Adjust to bundled tokens.
9837 (code_content): Remove; stripping is now done by add_param.
9838 (print_token_value): Print contents of bundled tokens.
9839 (token_name): New function.
9841 * src/reader.h (braced_code, current_braced_code): Remove.
9842 (token_name): New decl.
9844 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
9845 token_type, not braced_code code_kind. All uses changed.
9846 (SC_PRE_CODE): New state, for scanning after a keyword that
9847 has (or usually has) an immediately-following braced code.
9848 (token_type): New local var, to keep track of which token type
9849 to return when scanning braced code.
9850 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
9851 <INITIAL>"%parse-param", <INITIAL>"%printer",
9852 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
9853 instead of returning a token type immediately.
9854 (<INITIAL>"{"): Set token type.
9855 (<SC_BRACED_CODE>"}"): Use it.
9856 (handle_action_dollar, handle_action_at): Now returns bool
9857 indicating success. Fail if ! current_rule; this prevents a core dump.
9858 (handle_symbol_code_dollar, handle_symbol_code_at):
9859 Remove; merge body into caller.
9860 (handle_dollar, handle_at): Complain in invalid contexts.
9862 * NEWS, doc/bison.texinfo: Document the above.
9863 * NEWS: Fix years and program names in copyright notice.
9865 2002-12-17 Paul Eggert <eggert@twinsun.com>
9867 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
9868 Reporting, Table of Symbols): Omit mentions of %lex-param and
9869 %parse-param from the documentation for now.
9871 2002-12-15 Paul Eggert <eggert@twinsun.com>
9873 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
9874 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
9875 lookahead symbol, and which sets yychar in parser actions) and it
9876 disagreed with the Bison documentation. Bug
9877 reported by Andrew Walrond.
9879 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
9880 as the caller now does that.
9881 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
9882 (YYEMPTY): Parenthesize right hand side, since others use it.
9883 (yyparse): Don't assume that our generated code is the only code
9886 2002-12-13 Paul Eggert <eggert@twinsun.com>
9890 POSIX requires a "yacc" command.
9891 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
9892 (MOSTLYCLEANFILES): Add yacc.
9894 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
9895 as an alias for bison y.
9897 * po/LINGUAS: Add da.
9899 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
9900 problem with latest <getopt.h>.
9901 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
9903 * doc/fdl.texi: Upgrade to 1.2.
9904 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
9905 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
9906 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
9908 * config/install-sh: Sync with autotools.
9910 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
9911 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
9912 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
9913 locations are requested.
9914 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
9915 locations are requested.
9917 2002-12-12 Paul Eggert <eggert@twinsun.com>
9919 Remove unportable casts and storage allocation tricks.
9920 While we're at it, remove almost all casts, since they
9921 usually aren't needed and are a sign of trouble.
9923 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
9925 * src/derives.c (derives_compute): Do not subtract NTOKENS from
9926 the pointer DSET returned by malloc; this isn't portable.
9927 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
9928 Similarly for DERIVES.
9929 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
9930 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
9931 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
9933 * src/derives.c (derives_compute): Do not bother invoking
9934 int_of_rule_number, since rule numbers are integers.
9936 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
9937 rather than XMALLOC (char, N).
9939 * src/files.c (filename_split): Rewrite to avoid cast.
9941 * src/gram.h (symbol_number_as_item_number,
9942 item_number_as_symbol_number, rule_number_as_item_number,
9943 item_number_as_rule_number):
9944 Now inline functions rather than macros, to avoid casts.
9945 * src/state.h (state_number_as_int): Likewise.
9946 * src/tables.c (state_number_to_vector_number,
9947 symbol_number_to_vector_number): Likewise.
9949 * src/gram.h (int_of_rule_number): Remove; no longer used.
9951 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
9952 since the resulting storage is always stored into.
9954 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
9957 * src/muscle_tab.c (muscle_m4_output):
9958 Now inline. Return bool, not int.
9959 * src/state.c (state_compare): Likewise.
9960 * src/symtab.c (symbol_check_defined,
9961 symbol_check_alias_consistency, symbol_pack, symbol_translation,
9962 hash_compare_symbol, hash_symbol):
9964 * src/uniqstr.c (uniqstr_print): Likewise.
9965 * src/muscle_tab.c (muscle_m4_output_processor):
9966 New function, to avoid casts.
9967 * src/state.c (state_comparator, stage_hasher): Likewise.
9968 * src/symtab.c (symbol_check_defined_processor,
9969 symbol_check_alias_consistency_processor, symbol_pack_processor,
9970 symbol_translation_processor, hash_symbol_comparator,
9971 hash_symbol_hasher): Likewise.
9972 * src/uniqstr.c (uniqstr_print_processor): Likewise.
9973 * src/muscle_tab.c (muscles_m4_output):
9974 Use new functions instead of casting old functions unportably.
9975 * src/state.c (state_hash_new): Likewise.
9976 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
9977 symbols_token_translations_init):
9979 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
9981 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
9982 var instead of casting to long, to avoid casts.
9983 (prepare_states): Use MALLOC rather than alloca, so that we don't
9984 have to worry about alloca.
9985 * src/state.c (state_hash_lookup): Likewise.
9987 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
9988 local var instead of casting to unsigned char, to avoid casts.
9990 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
9991 STATE_ALLOC): Remove.
9992 (transitions_new, errs_new, reductions_new, state_new): Use malloc
9993 rather than calloc, and use offsetof to avoid allocating slightly
9995 (state_new): Initialize all members.
9997 * src/state.c (state_hash): Use unsigned accumulator, not signed.
9999 * src/symtab.c (symbol_free): Remove; unused.
10000 (symbol_get): Remove cast in lhs of assignment.
10001 (symbols_do): Now static. Accept generic arguments, not
10002 hashing-related ones.
10004 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
10005 (symbol_processor): Remove.
10006 (symbols_do): Remove decl; now static.
10008 * src/system.h (alloca): Remove; decl no longer needed.
10009 (<stddef.h>): Include, for offsetof.
10010 (<inttypes.>, <stdint.h>): Include if available.
10011 (uintptr_t): New type, if system lacks it.
10012 (CALLOC, MALLOC, REALLOC): New macros.
10013 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
10016 * src/tables.c (table_size): Now int, to pacify GCC.

10029 2002-12-09 Paul Eggert <eggert@twinsun.com>
10031 Change identifier spellings to avoid collisions with names
10032 that are reserved by POSIX.
10034 Don't use names ending in _t, since POSIX reserves them.
10035 For consistency, remove _e and _s endings -- they're weren't
10036 needed to remove ambiguity. All uses changed.
10037 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
10038 turn was just renamed from struniq_t.
10039 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
10040 which in turn was just renamed from struniq_processor_t.
10041 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

10112 value_t_as_yystype -> value_as_yystype.
10114 Don't include <errno.h> in the mainstream code, since it
10115 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
10116 * lib/get-errno.c, lib/get-errno.h: New files.
10117 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
10119 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

10127 (TAB_EXT): Renamed from EXT_TAB.
10128 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
10130 Avoid str[a-z]*, since <string.h> reserves that name space.
10131 Change all instances of "struniq" in names to "uniqstr", and
10132 likewise for "STRUNIQ" and "UNIQSTR".
10133 * src/uniqstr.c: Renamed from src/struniq.c.
10134 * src/uniqstr.h: Renamed from src/struniq.h.
10135 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
10136 * src/files.c (strsuffix): Remove; unused.

10145 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
10146 (N_EXPAND): Renamed from N_STRETCH.

10150 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

10157 (BASE_MINIMUM): Renamed from BASE_MIN.
10158 (ACTION_MAX): Remove; unused.
10159 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
10160 Unnecessary casts removed from above defines.
10163 Fix misspelling in names.
10164 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
10165 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
10169 * lib/timevar.c (timevar_report): Renamed from time_report,
10170 for consistency with other names.
10171 * lib/timevar.h (timevar_report): New decl.
10172 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
10175 Sort include-file uses.
10177 Reorder all include files under src to be in the order "system.h".
10178 then the ../lib include files in angle brackets (alphabetized),
10179 then the . include files in double-quotes (alphabetized). Fix
10180 dependency breakages encountered in this process, as follows:
10181 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
10182 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
10183 * src/state.h: Include "symtab.h".
10185 2002-12-08 Paul Eggert <eggert@twinsun.com>
10187 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
10188 since this causes problems when __file__ contains character
10189 sequences like "@" that are treated specially by src/scan-skel.l.
10190 Instead, just use the file's basename. This fixes the bug
10191 reported by Martin Mokrejs in
10192 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
10194 2002-12-06 Paul Eggert <eggert@twinsun.com>
10196 Add support for rules that do not have trailing semicolons, as
10197 POSIX requires. Improve the quality of locations in Bison
10200 * src/location.c: Include <quotearg.h>.
10201 (empty_location): Now const.
10202 (location_print): New function. Follow the recommendation of the
10203 GNU Coding Standards for locations that span file boundaries.
10204 * src/location.h: Do not include <quotearg.h>; no longer needed.
10205 (boundary): New type.
10206 (location_t): Use it. This allows locations to span file boundaries.
10207 All member uses changed: file -> start.file or end.file (as needed),
10208 first_line -> start.line, first_column -> start.column,
10209 last_line -> end.line, last_column -> end.column.
10210 (equal_boundaries): New function.
10211 (LOCATION_RESET, LOCATION_STEP): Remove.
10212 (LOCATION_PRINT): Remove. All callers changed to use location_print.
10213 (empty_location): Now const.
10214 (location_print): New decl.
10215 * src/parse-gram.y (lloc_default): New function, which handles
10216 empty locations more accurately.
10217 (YYLLOC_DEFAULT): Use it.
10218 (%token COLON): Remove.
10219 (%token ID_COLON): New token.
10221 (declarations, rules): Remove trailing semicolon.
10222 (declaration, rules_or_grammar_declaration):
10223 Allow empty (";") declaration.
10224 (symbol_def): Remove empty actions; no longer needed.
10225 (rules_or_grammar_declaration): Remove trailing semicolon.
10226 (semi_colon.opt): Remove.
10227 * src/reader.h: Include location.h.
10228 (scanner_cursor): New decl.
10229 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
10231 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
10233 (STEP): Remove. No longer needed, now that adjust_location does
10234 the work. All uses removed.
10235 (scanner_cursor): New var.
10236 (adjust_location): Renamed from extend_location. It now sets
10237 *loc and adjusts the scanner cursor. All uses changed.
10238 Don't bother testing for CR.
10239 (handle_syncline): Remove location arg; now updates scanner cursor.
10240 All callers changed.
10241 (unexpected_end_of_file): Now accepts start boundary of token or
10242 comment, not location. All callers changed. Update scanner cursor,
10244 (SC_AFTER_IDENTIFIER): New state.
10245 (context_state): Renamed from c_context. All uses changed.
10246 (id_loc, code_start, token_start): New local vars.
10247 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
10248 processing of Yacc white space and equivalents here.
10249 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
10250 instead of returning ID immediately, since we need to search for
10251 a subsequent colon.
10252 (<INITIAL>"'", "\""): Save token_start.
10253 (<INITIAL>"%{", "{", "%%"): Save code_start.
10254 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
10255 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
10256 BEGIN context_state at end, not INITIAL.
10257 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
10258 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
10259 Return correct token start.
10260 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
10261 the start of a character, string or multiline comment is found.
10262 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
10263 Reduction): Adjust reported locations to match the more-precise
10264 results now expected.
10265 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
10266 * tests/reduce.at (Useless Rules, Reduced Automaton,
10267 Underivable Rules): Likewise.
10268 * tests/regression.at (Invalid inputs): No longer `expecting ";"
10269 or "|"' now that so many other tokens are allowed by the new grammar.
10271 * src/complain.h (current_file): Remove duplicate decl;
10272 current_file is now owned by files.h.
10273 * src/complain.c, src/scan-gram.l: Include files.h.
10275 2002-12-06 Paul Eggert <eggert@twinsun.com>
10277 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
10278 promotes to int; it might be unsigned int.
10279 * data/yacc.c (yy_reduce_print): Likewise.
10281 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
10282 be #defined in the prologue, not in the Bison declarations.
10283 This fixes Debian Bug 102878, reported by Shaul Karl.
10285 2002-12-02 Paul Eggert <eggert@twinsun.com>
10287 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
10288 * lib/strtoul.c: New file, from gnulib.
10289 This fixes a porting bug reported by Peter Klein in
10290 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
10292 2002-11-30 Paul Eggert <eggert@twinsun.com>
10294 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
10295 and put only a forward declaration in the prologue. This is for
10296 consistency with the other scanner helper functions.
10298 Type clashes now generate warnings, not errors, since it
10299 appears that POSIX may allow some grammars with type clashes.
10300 * src/reader.c (grammar_current_rule_check): Warn about
10301 type clashes instead of complaining.
10302 * tests/input.at (Type Clashes): Expect warnings, not complaints.
10304 Add Yacc library, since POSIX requires it.
10305 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
10306 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
10307 * lib/main.c, lib/yyerror.c: New files.
10309 gram_error can be static; it need not be extern.
10310 * src/reader.h (gram_error): Remove decl.
10311 * src/parse-gram.y (gram_error): Now static. Add static decl.
10312 (print_token_value): Omit parameter names from forward decl,
10315 2002-11-29 Paul Eggert <eggert@twinsun.com>
10317 * doc/bison.texinfo: Emphasize that yylex and yyerror must
10318 be declared before being used. E.g., one should typically
10319 declare them in the prologue. Use GNU coding style in examples.
10320 Put "const" consistently after the type it modifies. Mention
10321 that C99 supports "inline". Mention that yyerror traditionally
10324 %parse-param and %lex-param now take just one argument, the
10325 declaration; the argument name is deduced from the declaration.
10327 * doc/bison.texinfo (Parser Function, Pure Calling, Error
10328 Reporting, Table of Symbols): Document this.
10329 * src/parse-gram.y (add_param): New function.
10331 (declaration): Implement new rule for %parse-param and %lex-param.
10332 * src/scan-gram.l: "," now elicits a warning, rather than being
10333 a token; this is more compatible with byacc.
10334 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
10336 2002-11-27 Paul Eggert <eggert@twinsun.com>
10338 Rename identifiers to avoid real and potential collisions.
10340 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
10341 to avoid collision with lex macro described by Bruce Lilly in
10342 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10343 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10344 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
10345 * src/parse-gram.y (print_token_value): Renamed from yyprint.
10347 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
10348 The name "yycontrol" violates the name space rules, and this stuff
10349 wasn't being used anyway.
10350 (input): Remove action; this stuff wasn't being used.
10351 (gram_error): Rename local variable yylloc -> loc.
10352 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
10353 (YY_DECL): Don't use "yy" at start of local variables.
10354 All uses changed, e.g., yylloc -> loc.
10355 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
10356 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
10357 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
10358 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
10360 * src/parse-gram.y (gram_error): loc is now const *.
10361 * src/reader.h (gram_error): Likewise.
10363 2002-11-24 Paul Eggert <eggert@twinsun.com>
10367 * tests/actions.at (Actions after errors): Use an output format
10368 more similar to that of the Printers and Destructors test.
10369 Test the position of the ';' token too.
10370 (Printers and Destructors): Likewise.
10371 (Printers and Destructors: %glr-parser): Remove for now, to avoid
10372 unnecessarily alarming people when the test fails.
10374 * data/yacc.c (yyerrlab1): Move this label down, so that the
10375 parser does not discard the lookahead token if the user code
10376 invokes YYERROR. This change is required for POSIX conformance.
10378 * lib/error.c: Sync with gnulib.
10380 2002-11-22 Paul Eggert <eggert@twinsun.com>
10382 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
10383 * lib/mbswidth.c, lib/mbswidth.h: Likewise.

10386 2002-11-20 Paul Eggert <eggert@twinsun.com>
10388 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
10390 2002-11-20 Paul Eggert <eggert@twinsun.com>
10392 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
10393 should use `if (! x) abort ();' rather than `assert (x);', and
10394 anyway it's one less thing to worry about configuring.
10396 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
10397 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
10398 and replace all instances of assert with abort.
10399 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
10400 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
10402 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
10403 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
10404 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
10405 hash_find_entry, hash_rehash, hash_insert): Likewise.
10406 * src/conflicts.c (resolve_sr_conflict): Likewise.
10407 * src/lalr.c (set_goto_map, map_goto): Likewise.
10408 * src/nullable.c (nullable_compute): Likewise.
10409 * src/output.c (prepare_rules, token_definitions_output): Likewise.
10410 * src/reader.c (packgram, reader): Likewise.
10411 * src/state.c (state_new, state_free, state_transitions_set,
10412 state_reduction_find): Likewise.
10413 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
10414 symbol_pack): Likewise.
10415 * src/tables.c (conflict_row, pack_vector): Likewise.
10416 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10417 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10418 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
10419 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
10421 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
10422 (ARGMATCH_CONSTRAINT): New macro.
10423 (ARGMATCH_ASSERT): Use it.
10425 * src/system.h (verify): New macro.
10426 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
10427 rather than assert.
10428 * src/tables.c (tables_generate): Likewise.
10430 * src/struniq.c (struniq_assert): Now returns void, and aborts
10431 if the assertion is false.
10432 (struniq_assert_p): Remove.
10433 * src/struniq.h: Likewise.
10435 2002-11-18 Paul Eggert <eggert@twinsun.com>
10437 * data/glr.c (yygetLRActions): Replace `yyindex' with
10438 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
10439 This fixes the regression with Sun ONE Studio 7 cc that I reported in
10440 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
10442 2002-11-18 Akim Demaille <akim@epita.fr>
10444 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
10446 From Tim Van Holder.
10448 2002-11-17 Paul Eggert <eggert@twinsun.com>
10450 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
10451 to "SyntaxError" for consistency with my 2002-11-15 change.
10453 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
10454 not define to {}, since this breaks the common use of `YYDPRINTF
10455 ((...));' if a single statement is desired (e.g. before `else').
10456 Work around GCC warnings by surrounding corresponding calls with
10458 (yyhasResolvedValue): Remove unused function.
10459 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
10461 (yyreportSyntaxError): Renamed from yyreportParseError.
10462 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
10464 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
10465 extern when possible. Remove unused initializations.
10467 2002-11-16 Akim Demaille <akim@epita.fr>
10469 Augment the similarity between GLR and LALR traces.
10471 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
10472 (YY_REDUCE_PRINT): New.
10473 (yyparse): Use them.
10474 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
10476 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
10477 state reached after the reduction/recovery, since...
10478 (yyparse, yyprocessOneStack): Report the state we are entering in.
10480 2002-11-16 Akim Demaille <akim@epita.fr>
10482 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
10483 Add support for --trace=skeleton.
10484 * src/scan-skel.l: %option debug.
10485 Scan strings of non-@ or \n instead of character by character.
10486 (scan_skel): Handle trace_skeleton.
10488 (@output_parser_name@, @output_header_name@): ``Restore'' their
10489 support (used to be M4 macros).
10490 * data/yacc.c: Quote larger chunks, a la glr.c.
10491 * data/lalr1.cc: Likewise.
10492 The header guards are no longer available, so use some other
10493 string than `YYLSP_NEEDED'.
10495 2002-11-16 Akim Demaille <akim@epita.fr>
10497 Make the ``Printers and Destructors'' test more verbose, taking
10498 `yacc.c''s behavior as (possibly wrong) reference.
10500 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
10501 instead of fprint on stdout.
10502 Set and report the last_line of the symbols.
10503 Consistently display values and locations.
10505 2002-11-16 Paul Eggert <eggert@twinsun.com>
10507 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
10509 2002-11-15 Paul Eggert <eggert@twinsun.com>
10511 * tests/actions.at (Actions after errors): New test case.
10513 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
10514 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
10515 tests/action.at, tests/calc.at, tests/conflicts.at,
10516 tests/cxx-type.at, tests/regression.at:
10517 "parse error" -> "syntax error" for POSIX compatibility.
10518 "parsing stack overflow..." -> "parser stack overflow" so
10519 that code matches Bison documentation.
10521 2002-11-15 Akim Demaille <akim@epita.fr>
10523 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
10524 take two BRACED_CODE, not two string_content.
10525 Free the scanner's obstack when we are done.
10526 (code_content): New.
10527 * tests/calc.at: Adjust.
10528 * doc/bison.texinfo: Adjust.
10529 Also, make sure to include the `,' for these declarations.
10531 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
10533 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
10534 definition; avoids potential autoreconf problems.
10536 2002-11-15 Akim Demaille <akim@epita.fr>
10538 Always check the value returned by yyparse.
10540 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
10541 returned by yyparse.
10542 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
10544 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
10545 returned by yyparse.
10547 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10549 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
10552 2002-11-14 Paul Eggert <eggert@twinsun.com>
10554 * src/output.c (output_skeleton): Call xfopen instead of
10555 duplicating xfopen's body.
10557 Fix bugs reported by Nelson H. F. Beebe in
10558 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
10560 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
10561 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
10562 Group compiler. Instead, use "$CC -E bar.c". Include the .h
10563 file twice in the grammar, as an extra check.
10565 * tests/input.at (Torturing the Scanner): Surround the
10566 backslash-newline tests with "#if 0", to make it less likely that
10567 we'll run into compiler bugs. Bring back solitary \ inside
10568 comment, but add a closing comment to work around HP C bug. Don't
10569 test backslash-newline in C character constant.
10571 2002-11-14 Akim Demaille <akim@epita.fr>
10573 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
10574 status of the compiler.
10575 Calling `exit 1' is no longer needed.
10576 Reported by Nelson H. F. Beebe.
10578 2002-11-14 Akim Demaille <akim@epita.fr>
10580 * tests/atlocal.in (CPPFLAGS): We have config.h.
10581 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
10583 * tests/actions.at, tests/calc.at, tests/conflicts.at,
10584 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
10585 * tests/regression.at, tests/torture.at: Use them for all the
10586 grammars that are to be compiled.
10587 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
10588 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
10589 * doc/bison.texinfo (GLR Parsers): Document `inline'.
10591 2002-11-14 Akim Demaille <akim@epita.fr>
10593 * doc/bison.texinfo: Various formatting changes (alignments in
10594 samples, additional @group/@end group, GCS in samples.
10595 Use @deffn instead of simple @table to define the directives,
10596 macros, variables etc.
10598 2002-11-13 Paul Eggert <eggert@twinsun.com>
10600 Fix some bugs reported by Albert Chin-A-Young in
10601 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
10603 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
10604 -o c"; the HP C compiler chatters during compilation.
10605 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
10606 * tests/headers.at (export YYLTYPE): Likewise.
10608 * tests/input.at (Torturing the Scanner): Remove lines containing
10609 solitary backslashes, as they tickle a bug in the HP C compiler.
10611 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
10612 comments, since they're not portable. Use GNU coding style.
10614 2002-11-13 Akim Demaille <akim@epita.fr>
10616 * data/yacc.c: Leave bigger chunks of quoted text.
10617 (YYDSYMPRINTF): New.
10618 Use it to report symbol activities.
10619 * data/glr.c (YYDSYMPRINTF): New.
10622 2002-11-12 Paul Eggert <eggert@twinsun.com>
10626 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
10627 (yyglrReduce): Return yyok, not 0.
10628 This should avoid the enumerated-type warnings reported
10629 by Nelson H. F. Beebe in
10630 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
10632 * lib/bbitset.h (BITSET_INLINE): Remove.
10633 * lib/bitset.h [! BITSET_INLINE]: Remove.
10634 (bitset_set, bitset_reset, bitset_test): Rename local vars
10635 to avoid shadowing warnings by GCC.
10637 * data/glr.c (inline): Remove #define. It's the user's
10638 responsibility to #define it away, just like 'const'.
10639 This fixes one of the bugs reported by Nelson H. F. Beebe in
10640 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
10642 * Makefile.maint (po-check): Scan .l and .y files instead of the
10643 .c and the .h files that they generate. This fixes the bug
10644 reported by Tim Van Holder in:
10645 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
10646 Look for N_ as well as for _. Try to avoid matching #define for
10648 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
10649 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
10650 * src/scan-gram.l: Revamp regular expressions so that " and '
10651 do not confuse xgettext.
10653 * src/struniq.h (struniq_new): Do not declare the return type
10654 to be 'const'; this violates the C standard.
10655 * src/struniq.c (struniq_new): Likewise.
10657 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
10659 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
10660 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
10663 2002-11-12 Akim Demaille <akim@epita.fr>
10665 * Makefile.maint: Sync with Autoconf:
10666 (local_updates): New.
10668 2002-11-12 Akim Demaille <akim@epita.fr>
10670 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
10672 2002-11-12 Akim Demaille <akim@epita.fr>
10674 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the

10679 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
10682 2002-11-12 Akim Demaille <akim@epita.fr>
10684 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
10685 Use it to test the GLR parser.
10687 2002-11-12 Akim Demaille <akim@epita.fr>
10689 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
10691 * data/glr.c (yystos): New.
10692 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
10693 (YYDSYMPRINT): New.
10694 (yyval): Don't define it, it is handled via M4.
10695 (yyrecoverParseError): Free verbosely the discarded symbols.
10696 * data/yacc.c (yysymprint): Remove, rather...
10697 (b4_yysymprint_generate): invoke.
10698 * data/c.m4 (b4_yysymprint_generate): New.
10699 Accept pointers as arguments, as opposed to the version from
10701 (b4_yydestruct_generate): Likewise.
10702 * tests/cations.at (Printers and Destructors): Use Bison directives
10703 instead of CPP macros.
10704 Don't rely on internal details.
10706 2002-11-12 Akim Demaille <akim@epita.fr>
10708 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
10709 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
10710 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
10711 it against YYEMPTY and so forth), work on yytoken (i.e., set
10712 it to YYEMPTY etc.).
10713 (yydestruct): Replace with a b4_yydestruct_generate invocation.
10714 (b4_symbol_actions): Remove.
10715 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
10716 for 0, end-of-input.
10718 2002-11-12 Akim Demaille <akim@epita.fr>
10720 * doc/bison.texinfo (Destructor Decl): New.
10722 2002-11-12 Akim Demaille <akim@epita.fr>
10724 * src/tables.c (tables_generate): Use free for pointers that
10725 cannot be NULL, not XFREE.
10726 (pack_vector): Use assert, not fatal, for bound violations.
10727 * src/state.c (state_new): Likewise.
10728 * src/reader.c (reader): Likewise.
10729 * src/lalr.c (set_goto_map): Likewise.
10730 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
10733 2002-11-12 Akim Demaille <akim@epita.fr>
10735 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
10737 * src/scan-gram.l (last_string): Is global to the file, not to
10739 * src/parse-gram.y (input): Don't append the epilogue here,
10740 (epilogue.opt): do it here, and free the scanner's obstack.
10741 * src/reader.c (epilogue_set): Rename as...
10742 (epilogue_augment): this.
10743 * data/c.m4 (b4_epilogue): Defaults to empty.
10745 2002-11-12 Akim Demaille <akim@epita.fr>
10747 * src/getargs.c (long_options): Remove duplicates.
10748 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
10750 * doc/bison.rnh: Remove.
10751 * doc/bison.texinfo (VMS Invocation): Remove.
10753 2002-11-12 Akim Demaille <akim@epita.fr>
10755 * src/struniq.h, src/struniq.c (struniq_t): Is const.
10756 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
10758 Use struniq for symbols.
10760 * src/symtab.h (symbol_t): The tag member is a struniq.
10761 (symbol_type_set): Adjust.
10762 * src/symtab.c (symbol_new): Takes a struniq.
10763 (symbol_free): Don't free the tag member.

10771 and type members are struniqs.
10772 * src/reader.c (get_merge_function)

10774 (TYPE, current_type): Are struniq.
10776 Use struniq for file names.
10778 * src/files.h, src/files.c (infile): Split into...
10779 (grammar_file, current_file): these.
10780 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.

10801 2002-11-11 Paul Eggert <eggert@twinsun.com>
10803 Revamp to fix many (but not all) of the C- and M4-related quoting
10804 problems. Among other things, this fixes the Bison bug reported
10805 by Jan Hubicka when processing the Bash grammar; see:
10806 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
10808 Use new @ escapes consistently. Represent brackets with @{ and @}
10809 rather than @<:@ and @:>@, since this works a bit better with dumb
10810 editors like vi. Represent @ with @@, since @ is now consistently
10811 an escape. Use @oline@ and @ofile@ rather than __oline__ and
10812 __ofile__, to avoid unexpected expansions. Similarly, use @output
10813 rather than #output.
10815 * data/c.m4 (b4_copyright): Omit file name from comment, since
10816 the file name could contain "*/".
10817 (b4_synclines_flag): Don't quote the 2nd argument; it should already
10818 be quoted. All uses changed.
10820 * data/glr.c: Use new @ escapes consistently.
10821 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
10822 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
10823 Remove, since they couldn't handle arbitrary characters in file
10825 * data/lalr1.cc: Likewise.
10826 * data/yacc.c: Likewise.
10828 * src/files.c (output_infix): Remove; all uses removed.
10829 * src/files.h: Likewise.
10831 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
10832 mishandled funny characters in file names, and anyway it isn't
10834 * data/yacc.c: Likewise.
10835 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
10837 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
10838 * data/yacc.c: Likewise.
10840 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
10842 (muscle_init): Quote filename as a C string.
10843 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
10844 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
10845 * src/output.c (escaped_file_name_output): New function.
10846 (prepare_symbols): Quote tokens for M4.
10847 (prepare): Don't insert output_infix, output_prefix,
10848 output_parser_name, output_header_name; this is now down by scan-skel.
10849 Insert skeleton as a C string.
10851 * src/output.c (user_actions_output, symbol_destructors_output,
10852 symbol_printers_output): Quote filenames for C and M4.
10853 * src/reader.c (prologue_augment, epilogue_set): Likewise.
10855 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
10856 escapes other than \\ and \'; this simplifies the code.
10857 (<SC_STRING>): Likewise, for \\ and \".
10858 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
10859 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
10860 Use new escapes @{ and @} for [ and ].
10862 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
10863 them with auto vars.
10864 Switch to new escape scheme, where @ is the escape character uniformly.
10865 Abort if a stray escape character is found. Avoid unbounded input
10866 buffer when parsing non-escaped text.
10868 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
10869 __oline__, #output, $@, and @{ do not have unintended meanings.
10871 2002-11-09 Paul Eggert <eggert@twinsun.com>
10873 Fix the test failure due to GCC warnings described in
10874 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
10875 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
10876 evaluate to 0 if it's impossible for NINF to be in the respective
10878 (yygetLRActions, yyrecoverParseError): Use them.
10880 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
10881 counted in the token inserted at end of file. Now takes
10882 location_t *, not location_t, so that the location can be
10883 adjusted. All uses changed.
10885 * tests/regression.at (Invalid inputs): Adjust wording in
10886 diagnostic to match the new behavior.
10888 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
10889 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
10890 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
10891 abort ();'. This reduces the runtime of the "Many lookaheads"
10892 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
10895 2002-11-07 Paul Eggert <eggert@twinsun.com>
10897 * src/parse-gram.y (CHARACTER): Remove unused token.
10900 * src/scan-gram.l: Remove stack option. We no longer use the
10901 stack, since the stack was never deeper than 1; instead, use the
10902 new auto var c_context to record the stacked value.
10904 Remove nounput option. At an unexpected end of file, we now unput
10905 the minimal input necessary to end cleanly; this simplifies the
10908 Avoid unbounded token sizes where this is easy.
10910 (unexpected_end_of_file): New function.
10911 Use it to systematize the error message on unexpected EOF.
10912 (last-string): Now auto, not static.

10917 not the (never otherwised-used) CHARACTER.
10919 2002-11-07 Akim Demaille <akim@epita.fr>
10921 Let yyerror always receive the msg as last argument, so that
10922 yyerror can be variadic.
10924 * data/yacc.c (b4_yyerror_args): New.
10925 Use it when calling yyerror.
10926 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

10972 either has GLR conflict entries.
10974 2002-11-05 Paul Eggert <eggert@twinsun.com>
10976 * src/scan-gram.l: Use more accurate diagnostics, e.g.
10977 "integer out of range" rather than "invalid value".
10978 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
10981 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
10982 Also, remove one static variable in the scanner.
10984 * src/scan-gram.l (braces_level): Now auto, not static.
10985 Initialize to zero if the compiler is being picky.
10986 (INITIAL): Clear braces_level instead of incrementing it.
10987 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
10988 as POSIX 1003.1-2001 requires.
10989 * src/system.h (IF_LINT): New macro, taken from coreutils.
10990 * configure.ac: Define "lint" if --enable-gcc-warnings.
10992 2002-11-05 Akim Demaille <akim@epita.fr>
10994 * src/scan-gram.l: When it starts with `%', complain about the
10995 whole directive, not just that `invalid character: %'.
10997 2002-11-04 Akim Demaille <akim@epita.fr>
10999 * Makefile.maint: Update from Autoconf.
11000 (update, cvs-update, po-update, do-po-update): New.

11015 * src/scan-gram.l: Use [\'] instead of ['] to pacify
11018 Use quote, not quote_n since LOCATION_PRINT no longer uses the
11021 2002-11-03 Paul Eggert <eggert@twinsun.com>
11023 * src/reader.c (get_merge_function, grammar_current_rule_check):
11024 Use consistent diagnostics for reporting type name clashes.
11025 Quote the types with <>, for consistency with Yacc.
11026 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
11028 2002-11-03 Akim Demaille <akim@epita.fr>
11030 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
11032 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
11033 (b4_parse_param): Remove.

11035 Propagate b4_pure_args where needed to pass them to yyerror.
11036 * data/glr.m4 (b4_parse_param): Remove.
11037 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

11042 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
11043 (yyreportAmbiguity): When using a pure parser, also need
11044 the location, and the parse-params.
11046 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
11047 When using a pure parser, also need the parse-params.
11049 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
11050 (%pure-parser + %parse-param) LALR and GLR parsers.
11051 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
11052 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

11059 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
11060 (Error Reporting): Adjust to these new directives.
11061 Document %error-verbose, deprecate YYERROR_VERBOSE.
11063 2002-11-03 Akim Demaille <akim@epita.fr>
11065 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
11066 AT_CHECK_CALC_GLR invocations to use % directives, instead of
11067 command line options.
11068 * tests/cxx-type.at: Formatting changes.
11070 2002-11-03 Paul Eggert <eggert@twinsun.com>
11072 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
11073 to count columns correctly, and to check for invalid inputs.
11075 Use mbsnwidth to count columns correctly. Account for tabs, too.
11076 Include mbswidth.h.
11077 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
11078 (extend_location): New function.
11079 (YY_LINES): Remove.
11081 Handle CRLF in C code rather than in Lex code.

11088 Handle backslash-newline correctly in C code.
11089 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
11090 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
11092 (tag, splice): New EREs. Do not allow NUL or newline in tags.
11093 Use {splice} wherever C allows backslash-newline.
11094 YY_STEP after space, newline, vertical-tab.
11095 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
11097 (letter, id): Don't assume ASCII; e.g., spell out a-z.
11099 ({int}, handle_action_dollar, handle_action_at): Check for integer
11102 (YY_STEP): Omit trailing semicolon, so that it's more like C.
11104 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
11105 as well as \000. Check for UCHAR_MAX, not 255.
11106 Allow \x with an arbitrary positive number of digits, as in C.
11107 Check for overflow here.
11108 Allow \? and UCNs, for compatibility with C.
11110 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
11111 with quote slot used by complain_at.
11113 * tests/input.at: Add tests for backslash-newline, m4 quotes
11114 in symbols, long literals, and funny escapes in strings.
11116 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
11117 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
11118 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.

11120 * m4/mbswidth.m4: New file, from GNU coreutils.
11122 * doc/bison.texinfo (Grammar Outline): Document // comments.
11123 (Symbols): Document that trigraphs have no special meaning in Bison,
11124 nor is backslash-newline allowed.
11125 (Actions): Document that trigraphs have no special meaning.

11130 2002-11-02 Paul Eggert <eggert@twinsun.com>
11132 * src/reader.c: Don't include quote.h; not needed.
11133 (get_merge_function): Reword warning to be consistent with
11134 type clash diagnostic in grammar_current_rule_check.
11136 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
11137 bug in trigraph handling.
11139 * src/output.c (prepare_symbols): When printing token names,
11140 escape "[" as "@<:@" and likewise for "]".
11142 * src/system.h (errno): Remove declaration, as we are now
11143 assuming C89 or better, and C89 guarantees errno.
11145 2002-10-30 Paul Eggert <eggert@twinsun.com>
11147 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
11148 Check for close failures.
11149 * src/files.h (xfclose): Return void, not int, since it always
11151 * src/files.c (xfclose): Likewise. Report I/O error if ferror
11153 * src/output.c (output_skeleton): Use xfclose rather than fclose
11154 and ferror. xfclose now checks ferror.
11156 * data/glr.c (YYLEFTMOST_STATE): Remove.
11157 (yyreportTree): Use a stack-based leftmost state. This avoids
11158 our continuing battles with bogus warnings about initializers.
11160 2002-10-30 Akim Demaille <akim@epita.fr>
11162 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
11165 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11167 * tests/glr-regr1.at: New test for reported regressions.
11168 * tests/testsuite.at: Add glr-regr1.at test.
11169 * tests/Makefile.am: Add glr-regr1.at test.

11175 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
11176 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
11177 we use malloc. Don't assume 'A' through 'Z' are contiguous.
11178 Don't assume strdup exists; POSIX says its an XSI extension.
11179 Check for buffer overflow on input.
11181 2002-10-24 Akim Demaille <akim@epita.fr>
11183 * src/output.c (output_skeleton): Don't disable M4sugar comments
11184 too soon: it results in comments being expanded.
11185 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
11188 2002-10-24 Akim Demaille <akim@epita.fr>
11190 * data/yacc.c (m4_int_type): New.
11191 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
11192 char' as only yacc.c wants K&R portability.
11193 * data/glr.c (yysigned_char): Remove.
11194 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
11195 Reported by Quoc Peyrot.
11197 2002-10-23 Paul Eggert <eggert@twinsun.com>
11199 * src/main.c (main): With --trace=time, report times even if a
11200 non-fatal error occurs. Formerly, the times were reported in some
11201 such cases but not in others.
11202 * src/reader.c (reader): Just return if a complaint has been issued,
11203 instead of exiting, so that 'main' can report times.
11205 2002-10-22 Akim Demaille <akim@epita.fr>
11207 * src/system.h: Include sys/types.
11208 Reported by Bert Deknuydt.
11210 2002-10-23 Paul Eggert <eggert@twinsun.com>
11212 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
11213 Suggested by Art Haas.
11215 2002-10-22 Paul Eggert <eggert@twinsun.com>
11217 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
11218 decl; not needed any more.
11219 * src/main.c (main): Use return to exit, undoing yesterday's change.
11220 The last OS that we could find where this wouldn't work is
11221 SunOS 3.5, and that's too old to worry about now.
11223 * data/glr.c (struct yyltype): Define members even when not
11224 doing locations. This is more consistent with yacc.c, and it
11225 works around the following bug reports:
11226 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
11227 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
11229 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
11230 @acronym consistently. Standardize on "Yacc" instead of "YACC",
11231 "Algol" instead of "ALGOL". Give a bit more history about BNF.
11233 2002-10-22 Akim Demaille <akim@epita.fr>
11235 * data/README: New.
11237 2002-10-21 Paul Eggert <eggert@twinsun.com>
11239 Be consistent about 'bool'; the old code used an enum in one
11240 module and an int in another, and this violates the C standard.
11241 * m4/stdbool.m4: New file, from coreutils 4.5.3.
11242 * configure.ac (AC_HEADER_STDBOOL): Add.
11243 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
11244 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
11245 * src/symtab.c (hash_compare_symbol_t): Likewise.
11246 * src/system.h (bool, false, true): Use a definition consistent
11247 with ../lib/hash.c. All uses changed.
11249 * src/complain.c (warning_issued): Renamed from warn_message_count,
11250 so that we needn't worry about integer overflow (!).
11251 Now of type bool. All uses changed.
11252 (complaint_issued): Renamed from complain_message_count; likewise.
11254 * src/main.c (main): Use exit to exit with failure.
11256 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
11257 rather than 1 and 0.
11258 * src/main.c (main): Likewise.
11259 * src/getargs.c (getargs): Likewise.
11260 * src/reader.c (reader): Likewise.
11262 * src/getarg.c (getargs): Remove duplicate code for
11263 "Try `bison --help'".
11265 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
11266 What was that "2" for?
11268 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
11269 * src/getargs.c (usage): Likewise.
11271 * src/getargs.c (getargs): When there are too few operands, report
11272 the last one. When there are too many, report the first extra
11273 one. This is how diffutils does it.
11275 2002-10-20 Paul Eggert <eggert@twinsun.com>
11277 Remove K&R vestiges.
11278 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
11279 * src/complain.c (VA_START): Remove. Assume prototypes.
11280 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
11281 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
11282 fatal): Assume prototypes.
11283 * src/complain.h: Assume prototypes.
11284 * src/system.h (PARAMS): Remove.
11285 Include <limits.h> unconditionally, since it's guaranteeed even
11286 for a freestanding C89 compiler.
11287 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
11288 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
11290 2002-10-20 Akim Demaille <akim@epita.fr>
11292 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
11293 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.

11297 (yy_reduce_print): New.
11298 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
11300 2002-10-20 Akim Demaille <akim@epita.fr>
11302 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
11303 arguments and output `void'.
11304 (b4_c_function): Rename as...
11305 (b4_c_function_def): this.
11306 (b4_c_function_decl, b4_c_ansi_function_def)
11307 (b4_c_ansi_function_decl): New.
11308 Change the interpretation of the arguments: before `int, foo', now
11310 * data/yacc.c (yyparse): Prototype and define thanks to these.
11311 Adjust b4_c_function_def uses.
11312 * data/glr.c (yyparse): Likewise, but ANSI only.
11314 2002-10-20 Akim Demaille <akim@epita.fr>
11316 * src/output.c (prepare): Move the definition of `tokens_number',
11317 `nterms_number', `undef_token_number', `user_token_number_max'
11319 (prepare_tokens): Here.
11320 (prepare_tokens): Rename as...
11321 (prepare_symbols): this.
11322 (prepare): Move the definition of `rules_number' to...
11323 (prepare_rules): here.
11324 (prepare): Move the definition of `last', `final_state_number',
11325 `states_number' to...
11326 (prepare_states): here.
11327 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
11329 2002-10-20 Akim Demaille <akim@epita.fr>
11331 * src/tables.h, src/tables.c, src/output.c: Comment changes.
11333 2002-10-20 Akim Demaille <akim@epita.fr>
11335 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
11338 2002-10-20 Akim Demaille <akim@epita.fr>
11340 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
11341 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
11343 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
11345 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
11346 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
11349 2002-10-19 Paul Eggert <eggert@twinsun.com>
11351 Do not create a temporary file, as that involves security and
11352 cleanup headaches. Instead, use a pair of pipes.
11353 Derived from a suggestion by Florian Krohm.
11354 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
11355 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
11356 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
11357 (BISON_PREREQ_SUBPIPE): Add.
11358 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
11359 Add subpipe.h, subpipe.c.
11360 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
11361 * po/POTFILES.in: Add lib/subpipe.c.
11362 * src/output.c: Include "subpipe.h".
11363 (m4_invoke): Remove decl.
11364 (scan_skel): New decl.
11365 (output_skeleton): Use pipe rather than temporary file for m4 input.
11366 Check that m4sugar.m4 is readable, to avoid deadlock.
11367 Check for pipe I/O error.
11368 * src/scan-skel.l (readpipe): Remove decl.
11369 (scan_skel): New function, to be used in place of m4_invoke.
11370 Read from stream rather than file.
11372 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
11373 float, as this generates a warning on Solaris 8 + GCC 3.2 with
11374 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
11375 this generates a more-accurate value anyway.
11377 * lib/timevar.c (timervar_accumulate): Rename locals to
11378 avoid confusion with similarly-named more-global.
11379 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
11381 * src/output.c (prepare): Use xstrdup to convert char const *
11382 to char *, to avoid GCC warning.
11384 2002-10-19 Akim Demaille <akim@epita.fr>
11386 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
11387 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
11388 Use them to have `calc.y' ready for %pure-parser.
11389 * data/yacc.c (YYLEX): Pass a yylex return type to
11390 b4_c_function_call.
11392 2002-10-19 Akim Demaille <akim@epita.fr>
11394 Prototype support of %lex-param and %parse-param.
11396 * src/parse-gram.y: Add the definition of the %lex-param and
11397 %parse-param tokens, plus their rules.
11398 Drop the `_' version of %glr-parser.
11400 * src/scan-gram.l (INITIAL): Scan them.
11401 * src/muscle_tab.c: Comment changes.
11402 (muscle_insert, muscle_find): Rename `pair' as `probe'.
11403 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
11404 (muscle_entry_s): The `value' member is no longer const.
11405 Adjust all dependencies.
11406 * src/muscle_tab.c (muscle_init): Adjust: use
11407 MUSCLE_INSERT_STRING.
11408 Initialize the obstack earlier.
11409 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
11410 (muscle_pair_list_grow): New.
11411 * data/c.m4 (b4_c_function_call, b4_c_args): New.
11412 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
11413 * tests/calc.at: Use %locations, not --locations.
11414 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
11416 2002-10-19 Akim Demaille <akim@epita.fr>
11418 * src/getargs.c (usage): Take status as argument and exit
11420 Report the traditional `Try ... --help' message when status != 0.
11421 (usage, version): Don't take a FILE * as arg, it is pointless.
11422 (getargs): When there is an incorrect number of arguments, make it
11423 an error, and report it GNUlically thanks to `usage ()'.
11425 2002-10-18 Paul Eggert <eggert@twinsun.com>
11427 * data/glr.c (yyreportParseError): Don't assume that sprintf
11428 yields the length of the printed string, as this is not true
11429 on SunOS 4.1.4. Reported by Peter Klein.
11431 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
11432 * tests/conflicts.at (%nonassoc and eof): Likewise.
11433 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
11435 2002-10-17 Akim Demaille <akim@epita.fr>
11437 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
11438 * src/getargs.c (trace_types, trace_args): Adjust.
11439 * src/reader.c (grammar_current_rule_prec_set)
11440 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
11441 Standardize error messages.
11442 And s/@prec/%prec/!
11443 (reader): Use trace_flag to enable scanner/parser debugging,
11444 instead of an adhoc scheme.
11445 * src/scan-gram.l: Remove trailing debugging code.
11447 2002-10-16 Paul Eggert <eggert@twinsun.com>
11449 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
11452 * NEWS: Officially drop support for building Bison with K&R C,
11453 since it didn't work anyway and it's not worth worrying about.
11454 * Makefile.maint (wget_files): Remove ansi2knr.c.
11455 (ansi2knr.c-url_prefix): Remove.
11456 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
11457 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11458 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11460 2002-10-15 Paul Eggert <eggert@twinsun.com>
11462 Stop using the "enum_" trick for K&R-style function definitions;
11463 it confused me, and I was the author! Instead, assume that people
11464 who want to use K&R C compilers (when using these modules in GCC,
11465 perhaps?) will run ansi2knr.
11467 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
11468 All uses of "enum_" changed to "enum ".
11469 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
11470 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
11472 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

11480 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
11481 Use function prototypes; this removes the need for declaring
11482 static functions simply to provide their prototypes.
11483 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

11542 * tests/Makefile.am (maintainer-check-posix): New.
11544 2002-10-14 Akim Demaille <akim@epita.fr>
11546 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
11549 2002-10-14 Akim Demaille <akim@epita.fr>
11551 * src/tables.c (table_ninf_remap): base -> tab.
11552 Reported by Matt Rosing.
11554 2002-10-14 Paul Eggert <eggert@twinsun.com>
11556 * tests/action.at, tests/calc.at, tests/conflicts.at,
11557 tests/cxx-type.at, tests/headers.at, tests/input.at,
11558 tests/regression.at, tests/synclines.at, tests/torture.at:
11559 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
11560 so that the tests still work even if POSIXLY_CORRECT is set.
11561 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
11563 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
11564 for portability to K&R hosts. Fix typo: signed char is guaranteed
11565 only to 127, not to 128.
11566 * data/glr.c (yysigned_char): New type.
11567 * data/yacc.c (yysigned_char): Likewise.
11568 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
11570 2002-10-13 Paul Eggert <eggert@twinsun.com>
11572 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
11573 true due to limited range of data type" warning from GCC.
11575 * data/c.m4 (b4_token_defines): Protect against double-inclusion
11576 by wrapping enum yytokentype's definition inside #ifndef
11577 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
11579 2002-10-13 Akim Demaille <akim@epita.fr>
11581 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
11582 Un yy- yyrhs to avoid the name clash with the global YYRHS.
11584 2002-10-13 Akim Demaille <akim@epita.fr>
11586 * Makefile.maint: Update from Autoconf 2.54.
11587 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
11589 2002-10-13 Akim Demaille <akim@epita.fr>
11591 * src/print.c (print_state): Separate the list of solved conflicts
11592 from the other items.
11593 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
11595 2002-10-13 Akim Demaille <akim@epita.fr>
11597 Let nondeterministic skeletons be usable with deterministic
11600 With the patch, GAWK compiled by GCC without -O2 passes its test
11601 suite using a GLR parser driven by LALR tables. It fails with -O2
11602 because `struct stat' gives two different answers on my machine:
11603 88 (definition of an auto var) and later 96 (memset on this var).
11604 Hence the stack is badly corrumpted. The headers inclusion is to
11605 blame: if I move the awk.h inclusion before GLR's system header
11606 inclusion, the two struct stat have the same size.
11608 * src/tables.c (pack_table): Always create conflict_table.
11609 (token_actions): Always create conflict_list.
11610 * data/glr.c (YYFLAG): Remove, unused.
11612 2002-10-13 Akim Demaille <akim@epita.fr>
11614 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
11616 (VALGRIND, GXX): New.
11617 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
11618 * tests/bison.in: Run $PREBISON a pre-command.
11619 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
11620 (maintainer-check-g++): New.
11621 * Makefile.am (maintainer-check): New.
11623 2002-10-13 Akim Demaille <akim@epita.fr>
11625 * data/glr.c: Formatting changes.
11626 Tweak some trace messages to match yacc.c's.
11628 2002-10-13 Akim Demaille <akim@epita.fr>
11630 GLR parsers sometimes raise parse errors instead of performing the
11632 Reported by Charles-Henry de Boysson.
11634 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
11635 check the length of the traces when %glr.
11636 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
11638 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
11640 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
11641 (yyltype): Remove the yy prefix from the member names.
11642 (yytable): Complete its comment.
11643 (yygetLRActions): Map error action number from YYTABLE from
11645 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
11646 (which was a bug: it should have been YYTABEL_NINF, and yet it was
11647 not satisfying as we could compare an YYACTION computed from
11648 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
11649 only value for error actions.
11650 (yyreportParseError): In verbose parse error messages, don't issue
11651 `error' in the list of expected tokens.
11652 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
11653 next action to perform to match glr.c's decoding.
11654 (yytable): Complete its comment.
11656 2002-10-13 Paul Eggert <eggert@twinsun.com>
11658 Fix problem reported by Henrik Grubbstroem in
11659 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
11660 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
11661 because the Bison parser reads the second action before reducing
11663 * src/scan-gram.l (rule_length): New static var.
11664 Use it to keep track of the rule length in the scanner, since
11665 we can't expect the parser to be in lock-step sync with the scanner.
11666 (handle_action_dollar, handle_action_at): Use this var.
11667 * tests/actions.at (Exotic Dollars): Test for the problem.
11669 2002-10-12 Paul Eggert <eggert@twinsun.com>
11671 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
11672 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
11673 Include <sys/time.h> when checking for clock_t and struct tms.
11674 Use same include order as source.
11675 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
11676 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
11678 * lib/timevar.c: Update copyright date and clarify comments.
11679 (get_time) [IN_GCC]: Keep the GCC version for reference.
11681 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
11682 GCC version as of today, then merge Bison's changes.
11683 Change "GCC" to "Bison" in copyright notice. timevar.def's
11684 author is Akim, so change that too.
11686 * src/reader.c (grammar_current_rule_check):
11687 Don't worry about the default action if $$ is untyped.
11688 Prevents bogus warnings reported by Jim Gifford in
11689 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
11691 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
11692 * data/glr.c, data/lalr1.cc, data/yacc.c:
11693 Output token definitions before the first part of user declarations.
11694 Fixes compatibility problem reported by Jim Gifford for kbd in
11695 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
11697 2002-10-11 Paul Eggert <eggert@twinsun.com>
11699 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
11700 (yyparse): here. This undoes some of the 2002-07-25 change.
11701 Compatibility problem reported by Ralf S. Engelschall with
11702 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

11721 * lib/lbitset.c: Likewise.
11723 * lib/abitset.c (abitset_bytes): Return a size that is aligned
11724 properly for vectors of objects. Do not assume that adding a

11726 properly aligned for the whole union.

11767 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
11769 Do not use "struct bitset_struct" to mean different things in
11770 different modules. Not only is this confusing, it violates
11771 the C Standard, which requires that structure types in different
11772 modules must be compatible if one is to be passed to the other.
11773 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
11774 All instances of "struct bitset_struct *" replaced with "bitset".

11818 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
11819 the same width as int. This reapplies a hunk of the 2002-08-12 patch
11820 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
11821 which was inadvertently undone by the 2002-09-30 patch.

12175 to void, to avoid a GCC warning when --disable-nls is in effect.
12177 * src/scan-gram.l: Use strings rather than escapes when possible,
12178 to minimize the number of warnings from xgettext.
12179 (handle_action_dollar, handle_action_at): Don't use isdigit,
12180 as it mishandles negative chars and it may not work as expected
12181 outside the C locale.
12183 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
12184 this is a GCC extension and is not portable to other compilers.

12423 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
12424 for the time being: %locations ought to provide it to yyerror.

14125 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
14126 full stderr, and strip it according to the bison options, instead
14127 of composing the error message from different bits.
14128 This makes it easier to check for several error messages.
14129 Adjust all the invocations.
14130 Add an invocation exercising the error token.
14131 Add an invocation demonstrating a stupid error message.
14132 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
14134 Error message are for stderr, not stdout.

14150 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
14151 `user_token_number_max'.
14152 Output `undef_token_number'.

14193 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
14194 passes, but produces negative #line number, once fixed, GCC is
14195 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of

14397 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
14398 lacking `+ 1' to nrules, Bison reported as useless a token if it
14399 was used solely to set the precedence of the last rule...
14401 2002-04-07 Akim Demaille <akim@epita.fr>
14403 * data/bison.c++, data/bison.simple: Don't output the current file
14404 name in #line, to avoid useless diffs between two identical
14405 outputs under different names.

14409 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

14425 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
14426 RHS, instead of being an index in RITEMS.
14428 2002-04-04 Paul Eggert <eggert@twinsun.com>
14430 * doc/bison.texinfo: Update copyright date.
14431 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

14610 * src/lalr.c (F): Now a bitset*.
14611 Adjust all dependencies.

14615 * src/conflicts.c (shiftset, lookaheadset): Now bitset.
14616 Adjust all dependencies.

14620 * src/L0.c, src/LR0.h (nstates): Be size_t.
14621 Adjust comparisons (signed vs unsigned).

14629 Adjust all dependencies.
14630 (varsetsize): Remove, now unused.

14633 2002-03-04 Akim Demaille <akim@epita.fr>
14635 * src/print.c: Convert to use bitset.h, not hand coded iterations
14638 2002-03-04 Akim Demaille <akim@epita.fr>
14640 * src/reduce.c: Convert to use bitset.h, not hand coded BSet.
14642 2002-03-04 Akim Demaille <akim@epita.fr>
14644 * src/closure.c (ruleset): Be a bitset.
14645 (rulesetsize): Remove.

14654 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
14656 * data/bison.c++: Merge the two generated headers. Insert a copyright
14657 notice in each output file.
14659 2002-02-28 Akim Demaille <akim@epita.fr>
14661 * data/bison.c++: Copy the prologue of bison.simple to fetch
14662 useful M4 definitions, such as b4_header_guard.
14664 2002-02-25 Akim Demaille <akim@epita.fr>
14666 * src/getargs.c (version): Give the name of the authors, and use a
14667 translator friendly scheme for the bgr
14670 2002-02-25 Akim Demaille <akim@epita.fr>
14672 * src/output.c (header_output): Remove, now handled completely via
14675 2002-02-25 Akim Demaille <akim@epita.fr>
14677 * m4/m4.m4: New, from CVS Autoconf.
14678 * configure.in: Invoke it.
14679 * src/output.c (output_skeleton): Use its result instead of the
14682 2002-02-25 Akim Demaille <akim@epita.fr>
14684 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
14686 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
14687 * src/output.c (output_skeleton): Use mkstemp to create a real
14689 Move the filling of `skeleton' and its muscle to...
14691 (output): Move the definition of the prologue muscle to...
14693 * src/system.h (DEFAULT_TMPDIR): New.
14695 2002-02-14 Paul Eggert <eggert@twinsun.com>
14697 Remove the support for C++ namespace cleanliness; it was
14698 causing more problems than it was curing, since it didn't work
14699 properly on some nonstandard C++ compilers. This can wait
14700 for a proper C++ parser.
14702 * NEWS: Document this.
14703 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
14704 of C++, as it's treated like C now.
14705 * src/bison.simple (YYSTD): Remove.
14706 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
14707 Treat C++ just like Standard C instead of trying to support
14708 namespace cleanliness.
14710 2002-02-14 Akim Demaille <akim@epita.fr>
14712 * tests/regression.at (else): Adjust to Andreas' change.
14714 2002-02-14 Akim Demaille <akim@epita.fr>
14716 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
14718 2002-02-13 Andreas Schwab <schwab@suse.de>
14720 * src/output.c (output_rule_data): Don't output NULL, it might
14721 not be defined yet.
14723 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
14725 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
14726 (Copyright notice): Update.
14728 2002-02-11 Akim Demaille <akim@epita.fr>
14730 * tests/regression.at (%nonassoc and eof): Don't include
14731 nonportable headers.
14733 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
14735 * data/bison.c++: Correct error recovery. Make the user able to
14736 initialize the starting location.
14738 2002-02-07 Akim Demaille <akim@epita.fr>
14740 * tests/input.at: New.
14742 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14744 * data/bison.c++: Replace some direct m4 expansions by constants. Be
14745 more consistent when naming methods and variables. Put preprocessor
14746 directives around tables only needed for debugging.
14748 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14750 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
14752 (yy::b4_name::parse): Use print_.
14754 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14756 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
14758 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14760 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
14762 (yy::b4_name::parse): Build verbose error messages, and use error_.
14764 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
14766 * data/bison.c++: Fix m4 quoting in comments.
14768 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
14770 * data/bison.c++: Adjust the parser code. Fix some muscles that were
14771 not expanded by m4.
14773 2002-02-05 Akim Demaille <akim@epita.fr>
14775 * data/bison.c++: Adjust to the M4 back end.
14776 More is certainly needed.
14778 2002-02-05 Akim Demaille <akim@epita.fr>
14780 Give a try to M4 as a back end.
14782 * lib/readpipe.c: New, from wdiff.
14783 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
14785 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
14786 specific values. Now it is m4 that performs the lookup.
14787 * src/parse-skel.y: Remove.
14788 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
14789 * src/output.c (actions_output, guards_output)
14790 (token_definitions_output): No longer keeps track of the output
14791 line number, hence remove the second argument.
14792 (guards_output): Check against the guard member of a rule, not the
14795 (output_skeleton): Don't look for the skeleton location, let m4 do
14797 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
14799 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
14800 (prepare): Given that for the time being changesyntax is not
14801 usable in M4, rename the muscles using `-' to `_'.
14802 Define `defines_flag', `output_parser_name' and `output_header_name'.
14803 * src/output.h (actions_output, guards_output)
14804 (token_definitions_output): Adjust prototypes.
14805 * src/scan-skel.l: Instead of scanning the skeletons, it now
14806 processes the output of m4: `__oline__' and `#output'.
14807 * data/bison.simple: Adjust to be used by M4(sugar).
14808 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
14810 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
14811 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
14812 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
14813 shamelessly stolen from CVS Autoconf.
14815 2002-02-05 Akim Demaille <akim@epita.fr>
14817 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
14818 * configure.in: Check for the declarations of free and malloc.
14819 * src/muscle_tab.c: Adjust.
14821 2002-02-05 Akim Demaille <akim@epita.fr>
14823 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
14824 which have no values.
14826 2002-02-05 Akim Demaille <akim@epita.fr>
14828 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
14831 2002-01-29 Paul Eggert <eggert@twinsun.com>
14833 * src/bison.simple (YYSIZE_T): Do not define merely because
14834 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
14835 On some platforms, <alloca.h> does not declare YYSTD (size_t).
14837 2002-01-27 Akim Demaille <akim@epita.fr>
14839 Fix `%nonassoc and eof'.
14841 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
14842 which were not properly copied! Replace
14843 memcpy (res->errs, src->errs, src->nerrs);
14845 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
14847 * tests/regression.at (%nonassoc and eof): Adjust to newest
14848 Autotest: `.' is not in the PATH.
14850 2002-01-27 Akim Demaille <akim@epita.fr>
14852 * tests/sets.at (AT_EXTRACT_SETS): New.
14853 (Nullable): Use it.
14856 2002-01-26 Akim Demaille <akim@epita.fr>
14858 * tests/actions.at, tests/calc.at, tests/headers.at,
14859 * tests/torture.at: Adjust to the newest Autotest which no longer
14860 forces `.' in the PATH.
14862 2002-01-25 Akim Demaille <akim@epita.fr>
14864 * tests/regression.at (%nonassoc and eof): New.
14865 Suggested by Robert Anisko.
14867 2002-01-24 Akim Demaille <akim@epita.fr>
14869 Bison dumps core when trying to complain about broken input files.
14870 Reported by Cris van Pelt.
14872 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
14873 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
14875 (Invalid inputs): Strengthen: exercise parse_percent_token.
14877 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
14879 * src/Makefile.am: Add bison.c++.
14880 * src/bison.c++: New skeleton.
14882 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
14886 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
14888 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
14890 2002-01-20 Marc Autret <marc@gnu.org>
14892 * src/files.c (compute_output_file_names): Fix
14894 2002-01-20 Marc Autret <marc@gnu.org>
14896 * tests/output.at: New test.
14897 * src/files.c (compute_base_names): Don't map extensions when
14898 the YACC flag is set, use defaults.
14899 Reported by Evgeny Stambulchik.
14901 2002-01-20 Marc Autret <marc@gnu.org>
14903 * src/system.h: Need to define __attribute__ away for non-GCC
14904 compilers as well (i.e., the vendor C compiler).
14905 Suggested by Albert Chin-A-Young.
14907 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
14909 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
14910 canonical definition.
14911 * src/system.h: Use the canonical definition for PARAMS (avoids
14912 a conflict with the macro from lib/hash.h).
14914 2002-01-11 Akim Demaille <akim@epita.fr>
14916 * configure.in: Use AC_FUNC_STRNLEN.
14917 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
14919 2002-01-09 Akim Demaille <akim@epita.fr>
14921 * src/files.c, src/files.h (output_infix): New.
14922 (tab_extension): Remove.
14923 (compute_base_names): Compute the former, drop the latter.
14924 * src/output.c (prepare): Insert the muscles `output-infix', and
14926 * src/parse-skel.y (string, string.1): New.
14927 (section.header): Use it.
14928 (section.yacc): Remove.
14929 (prefix): Remove too.
14930 * src/scan-skel.l: Adjust.
14931 * src/bison.simple, src/bison.hairy: Adjust.
14933 2002-01-09 Akim Demaille <akim@epita.fr>
14935 * configure.in (WERROR_CFLAGS): Compute it.
14936 * src/Makefile.am (CFLAGS): Pass it.
14937 * tests/atlocal.in (CFLAGS): Idem.
14938 * src/files.c: Fix a few warnings.
14939 (get_extension_index): Remove, unused.
14941 2002-01-08 Akim Demaille <akim@epita.fr>
14943 * src/getargs.c (AS_FILE_NAME): New.
14944 (getargs): Use it to convert DOSish file names.
14945 * src/files.c (base_name): Rename as full_base_name to avoid
14946 clashes with `base_name ()'.
14947 (filename_split): New.
14948 (compute_base_names): N-th rewrite, using filename_split.
14950 2002-01-08 Akim Demaille <akim@epita.fr>
14952 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
14953 New, stolen from the Fileutils 4.1.
14954 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
14955 * configure.in: Check for the presence of memrchr, and of its
14958 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
14960 * lib/hash.h (__P): Added definition for this macro.
14961 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
14962 BUILT_SOURCES, to ensure they are generated first.
14963 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
14964 %error-verbose to allow bootstrapping with bison 1.30x.
14966 2002-01-06 Akim Demaille <akim@epita.fr>
14968 * src/reader.c (parse_braces): Don't fetch the next char, the
14969 convention is to fetch on entry.
14970 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
14971 'switch' without a following semicolon.
14972 * tests/regression.at (braces parsing): New.
14974 2002-01-06 Akim Demaille <akim@epita.fr>
14976 Bison is dead wrong in its RR conflict reports.
14978 * tests/torture.at (GNU Cim Grammar): New.
14979 * src/conflicts.c (count_rr_conflicts): Fix.
14981 2002-01-06 Akim Demaille <akim@epita.fr>
14983 Creating package.m4 from configure.ac causes too many problems.
14985 * tests/Makefile.am (package.m4): Create it by hand,
14986 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
14988 2002-01-06 Akim Demaille <akim@epita.fr>
14990 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
14993 2002-01-04 Paul Eggert <eggert@twinsun.com>
14995 * doc/bison.texinfo (Debugging):
14996 Remove YYSTDERR; it's no longer defined or used.
14997 Also, s/cstdio.h/cstdio/.
14999 2002-01-03 Akim Demaille <akim@epita.fr>
15001 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
15003 2002-01-03 Akim Demaille <akim@epita.fr>
15005 * src/parse-skel.y (process_skeleton): Don't bind the parser's
15006 tracing code to --trace, wait for a better --trace option, with
15009 2002-01-03 Akim Demaille <akim@epita.fr>
15011 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
15012 The ISO C++ standard is extremely clear about it: stderr is
15013 considered a macro, not a regular symbol (see table 94 `Header
15014 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
15015 Therefore std:: does not apply to it. It still does with fprintf.
15016 Also, s/cstdio.h/cstdio/.
15018 2002-01-03 Akim Demaille <akim@epita.fr>
15020 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
15021 for non system headers.
15023 2002-01-02 Akim Demaille <akim@epita.fr>
15025 Equip the skeleton chain with location tracking, runtime trace,
15026 pure parser and scanner.
15028 * src/parse-skel.y: Request a pure parser, locations, and prefix
15030 (%union): Having several members with the same type does not help
15031 type mismatches, simplify.
15032 (YYPRINT, yyprint): New.
15033 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
15034 (skel_error): this.
15036 * src/scan-skel.l: Adjust to these changes.
15037 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
15038 (LOCATION_PRINT, skel_control_t): New.
15040 2001-12-30 Akim Demaille <akim@epita.fr>
15042 * src/parse-skel.y: Get rid of the shift/reduce conflict:
15043 replace `gb' with BLANKS.
15044 * src/scan-skel.l: Adjust.
15046 2001-12-30 Akim Demaille <akim@epita.fr>
15048 * src/system.h: We don't need nor want bcopy.
15049 Throw away MS-DOS crap: we don't need getpid.
15050 * configure.in: We don't need strndup. It was even causing
15051 problems: because Flex includes the headers *before* us,
15052 _GNU_SOURCE is not defined by config.h, and therefore strndup was
15054 * lib/xstrndup.c: New.
15055 * src/scan-skel.l: Use it.
15056 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
15057 * src/parse-skel.y: Use %directives instead of #defines.
15059 2001-12-30 Akim Demaille <akim@epita.fr>
15061 * src/skeleton.h: New.
15062 * src/output.c (output_parser, output_master_parser): Remove, dead
15064 * src/output.h (get_lines_number, actions_output, guards_output)
15065 (token_definitions_output): Prototype them.
15066 * src/parse-skel.y: Add the license notice.
15067 Include output.h and skeleton.h.
15068 (process_skeleton): Returns void, and takes a single parameter.
15069 * src/scan-skel.l: Add the license notice.
15070 Include skeleton.h.
15071 Don't use %option yylineno: it seems that then Flex imagines
15072 REJECT has been used, and therefore it won't reallocate its
15073 buffers (which makes no other sense to me than a bug). It results
15074 in warnings for `unused: yy_flex_realloc'.
15076 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
15078 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15079 (MUSCLE_INSERT_PREFIX): ...to there.
15080 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15081 (MUSCLE_INSERT_PREFIX): Move from here...
15083 * src/bison.hairy: Add a section directive. Put braces around muscle
15084 names. This parser skeleton is still broken, but Bison should not
15085 choke on a bad muscle 'syntax'.
15086 * src/bison.simple: Add a section directive. Put braces around muscle
15089 * src/files.h (strsuffix, stringappend): Add declarations.
15090 (tab_extension): Add declaration.
15091 (short_base_name): Add declaration.
15093 * src/files.c (strsuffix, stringappend): No longer static. These
15094 functions are used in the skeleton parser.
15095 (tab_extension): New.
15096 (compute_base_names): Use the computations done in this function
15097 to guess if the generated parsers should have '.tab' in their
15099 (short_base_name): No longer static.
15101 * src/output.c (output_skeleton): New.
15102 (output): Disable call to output_master_parser, and give a try to
15103 a new skeleton handling system.
15104 (guards_output, actions_output): No longer static.
15105 (token_definitions_output, get_lines_number): No longer static.
15107 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
15109 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
15112 * src/parse-skel.y: New file.
15113 * src/scan-skel.l: New file.
15115 2001-12-29 Akim Demaille <akim@epita.fr>
15117 %name-prefix is broken.
15119 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
15120 Adjust all dependencies.
15121 * tests/headers.at (export YYLTYPE): Strengthen this test: use
15124 Renaming yylval but not yylloc is not consistent. Now we do.
15126 * src/bison.simple: Prefix yylloc if used.
15127 * doc/bison.texinfo (Decl Summary): Document that.
15129 2001-12-29 Akim Demaille <akim@epita.fr>
15131 * doc/bison.texinfo: Promote `%long-directive' over
15133 Remove all references to fixed-output-files, yacc is enough.
15135 2001-12-29 Akim Demaille <akim@epita.fr>
15137 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
15138 user prologue. These are defaults.
15139 * tests/actions.at (Mid-rule actions): Make sure the user can
15140 define YYDEBUG and YYERROR_VERBOSE.
15142 2001-12-29 Akim Demaille <akim@epita.fr>
15144 * src/output.c (header_output): Don't forget to export YYLTYPE and
15146 * tests/headers.at (export YYLTYPE): New, make sure it does.
15147 * tests/regression.at (%union and --defines, Invalid CPP headers):
15149 * tests/headers.at: here.
15151 2001-12-29 Akim Demaille <akim@epita.fr>
15153 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
15155 2001-12-29 Akim Demaille <akim@epita.fr>
15157 * tests/actions.at (Mid-rule actions): Output on a single line
15158 instead of several.
15160 2001-12-29 Akim Demaille <akim@epita.fr>
15162 * doc/bison.texinfo: Formatting changes.
15164 2001-12-29 Akim Demaille <akim@epita.fr>
15166 Don't store the token defs in a muscle, just be ready to output it
15167 on command. Now possible via `symbols'. Fixes a memory leak.
15169 * src/output.c (token_definitions_output): New.
15170 (output_parser, header_output): Use it.
15171 * src/reader.c (symbols_save): Remove.
15173 2001-12-29 Akim Demaille <akim@epita.fr>
15175 * src/bison.simple: Do not provide a default for YYSTYPE and
15176 YYLTYPE before the user's prologue. Otherwise it's hardly... a
15179 2001-12-29 Akim Demaille <akim@epita.fr>
15181 Mid-rule actions are simply... ignored!
15183 * src/reader.c (readgram): Be sure to attach mid-rule actions to
15184 the empty-rule associated to the dummy symbol, not to the host
15186 * tests/actions.at (Mid-rule actions): New.
15188 2001-12-29 Akim Demaille <akim@epita.fr>
15192 * src/reader.c (reader): Free grammar.
15194 2001-12-29 Akim Demaille <akim@epita.fr>
15198 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
15199 since it allocates it for each state, although only one is needed.
15200 (allocate_storage): Do it here.
15202 2001-12-29 Akim Demaille <akim@epita.fr>
15204 * src/options.h, src/options.c (create_long_option_table): Rename
15206 (long_option_table_new): this, with a clearer prototype.
15207 (percent_table): Remove, unused,
15208 * src/getargs.c (getargs): Adjust.
15210 2001-12-29 Akim Demaille <akim@epita.fr>
15212 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

15216 2001-12-29 Akim Demaille <akim@epita.fr>
15218 * src/lalr.c (build_relations): Rename `states' as `states1'.
15219 Sorry, I don't understand exactly what it is, no better name...
15221 2001-12-29 Akim Demaille <akim@epita.fr>
15223 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
15224 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

15240 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
15241 Adjust all users to use symbols[i]->prec or ->assoc.

15245 * src/reader.c, src/reader.h (tags): Remove.
15246 Adjust all users to use symbols[i]->tag.
15248 2001-12-29 Akim Demaille <akim@epita.fr>
15250 * src/gram.h, src/gram.c (symbols): New, similar to state_table
15252 * src/reader.c (packsymbols): Fill this table.
15254 * src/conflicts.c (resolve_sr_conflict): Adjust.
15255 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
15257 Use symbols[i]->tag instead of tags[i].
15259 2001-12-29 Akim Demaille <akim@epita.fr>
15261 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
15262 In addition, put a comment in there, to replace...
15263 * tests/regression.at (%union and C comments): Remove.
15265 2001-12-29 Akim Demaille <akim@epita.fr>
15267 * tests/regression.at (Web2c Actions): Blindly move the actual
15268 output as expected output. The contents *seem* right to me, but I
15269 can't pretend reading perfectly parser tables... Nonetheless, all
15270 the other tests pass correctly, the table look OK, even though the
15271 presence of `$axiom' is to be noted: AFAICS it is useless (but
15274 2001-12-29 Akim Demaille <akim@epita.fr>
15276 * src/reader.c (readgram): Don't add the rule 0 if there were no
15277 rules read. In other words, add it _after_ having performed
15278 grammar sanity checks.
15279 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
15281 2001-12-29 Akim Demaille <akim@epita.fr>
15283 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
15284 visible, and some states have now a different number.
15286 2001-12-29 Akim Demaille <akim@epita.fr>
15288 * src/reader.c (readgram): Bind the initial rule's lineno to that
15290 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
15291 (Solved SR Conflicts): Adjust rule 0's line number.
15293 2001-12-29 Akim Demaille <akim@epita.fr>
15295 Fix the `GAWK Grammar' failure.
15297 * src/LR0.c (final_state): Initialize to -1 so that we do compute
15298 the reductions of the first state which was mistakenly confused
15299 with the final state because precisely final_state was initialized
15301 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
15302 now noticed by Bison.
15303 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
15304 have a reduction on $default.
15306 2001-12-29 Akim Demaille <akim@epita.fr>
15308 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
15310 * src/closure.c (print_closure): Likewise.
15311 * src/derives.c (print_derives): Likewise.
15312 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
15315 2001-12-29 Akim Demaille <akim@epita.fr>
15317 * src/lalr.c (lookaheads_print): New.
15318 (lalr): Call it when --trace-flag.
15319 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
15322 2001-12-29 Akim Demaille <akim@epita.fr>
15324 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
15325 when walking through ritem, even via rule->rhs.
15326 * src/reduce.c (dump_grammar, useful_production, reduce_output)
15327 (useful_production, useless_nonterminals): Likewise.
15328 (reduce_grammar_tables): Likewise, plus update nritems.
15329 * src/nullable.c (set_nullable): Likewise.
15330 * src/lalr.c (build_relations): Likewise.
15331 * tests/sets.at (Nullable): Adjust.
15332 Fortunately, now, the $axiom is no longer nullable.
15334 2001-12-29 Akim Demaille <akim@epita.fr>
15336 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

15339 * src/reduce.c (nonterminals_reduce): Likewise.
15340 * src/print_graph.c (print_graph): Likewise.

15342 * src/nullable.c (set_nullable): Likewise.
15344 2001-12-29 Akim Demaille <akim@epita.fr>
15346 * src/output.c: Comment changes.
15348 2001-12-27 Paul Eggert <eggert@twinsun.com>
15350 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
15351 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
15352 Sparc, as they were causing more porting problems than the
15353 (minor) performance improvement was worth.
15355 Also, catch up with 1.31's YYSTD.
15357 2001-12-27 Akim Demaille <akim@epita.fr>
15359 * src/output.c (output_gram): Rely on nritems, not the
15360 0-sentinel. See below.
15361 Use -1 as separator, not 0.
15362 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
15363 Rely on -1 as separator in yyrhs, instead of 0.
15364 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
15365 twice `Now at end of input', therefore there are two lines less to
15368 2001-12-27 Akim Demaille <akim@epita.fr>
15370 * tests/regression.at (Unresolved SR Conflicts):
15371 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
15374 2001-12-27 Akim Demaille <akim@epita.fr>
15376 * src/LR0.c (new_state): Recognize the final state by the fact it
15377 is reached by eoftoken.
15378 (insert_start_shifting_state, insert_eof_shifting_state)
15379 (insert_accepting_state, augment_automaton): Remove, since now
15380 these states are automatically computed from the initial state.
15381 (generate_states): Adjust.
15382 * src/print.c: When reporting a rule number to the user, substract
15383 1, so that the axiom rule is rule 0, and the first user rule is 1.
15384 * src/reduce.c: Likewise.
15385 * src/print_graph.c (print_core): For the time being, just as for
15386 the report, depend upon --trace-flags to dump the full set of
15388 * src/reader.c (readgram): Once the grammar read, insert the rule
15389 0: `$axiom: START-SYMBOL $'.
15390 * tests/set.at: Adjust: rule 0 is now displayed, and since the
15391 number of the states has changed (the final state is no longer
15392 necessarily the last), catch up.
15394 2001-12-27 Akim Demaille <akim@epita.fr>
15396 Try to make the use of the eoftoken valid. Given that its value
15397 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
15398 is used instead of > 0 where appropriate, (ii), depend upon nritems
15399 instead of the 0-sentinel.
15401 * src/gram.h, src/gram.c (nritems): New.
15402 Expected to be duplication of nitems, but for the time being...
15403 * src/reader.c (packgram): Assert nritems and nitems are equal.
15404 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
15405 * src/closure.c (print_closure, print_fderives): Likewise.

15410 2001-12-27 Akim Demaille <akim@epita.fr>
15412 * src/main.c (main): If there are complains after grammar
15413 reductions, then output the report anyway if requested, then die.
15414 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
15415 * src/reader.c (eoftoken): New.
15416 (parse_token_decl): If the token being defined has value `0', it
15418 (packsymbols): No longer hack `tags' to insert `$' by hand.
15419 Be sure to preserve the value of the eoftoken.
15420 (reader): Make sure eoftoken is defined.
15421 Initialize nsyms to 0: now eoftoken is created just like the others.
15422 * src/print.c (print_grammar): Don't special case the eof token.
15423 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
15424 lie anyway, albeit pleasant.
15425 * tests/calc.at: Exercise error messages with eoftoken.
15426 Change the grammar so that empty input is invalid.
15427 Adjust expectations.
15428 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
15430 2001-12-27 Akim Demaille <akim@epita.fr>
15432 * configure.in: Check the protos of strchr ans strspn.
15433 Replace strchr if needed.
15434 * src/system.h: Provide the protos of strchr, strspn and memchr if
15436 * lib/strchr.c: New.
15437 * src/reader.c (symbols_save): Use strchr.
15439 2001-12-27 Akim Demaille <akim@epita.fr>
15441 * src/print.c, src/print_graph.c (escape): New.
15442 Use it to quote the TAGS outputs.
15443 * src/print_graph.c (print_state): Now errors are in red, and
15444 reductions in green.
15445 Prefer high to wide: output the state number on a line of its own.
15447 2001-12-27 Akim Demaille <akim@epita.fr>
15449 * src/state.h, src/state.c (reductions_new): New.
15450 * src/LR0.c (set_state_table): Let all the states have a
15451 `reductions', even if reduced to 0.
15452 (save_reductions): Adjust.

15470 2001-12-27 Akim Demaille <akim@epita.fr>
15472 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
15473 * src/print.c: here.
15474 (lookaheadset, shiftset): New, used as additional storage by
15476 (print_results): Adjust.
15477 (print_shifts, print_gotos, print_errs): New, extracted from...
15478 (print_actions): here.
15479 * src/print_graph.c (print_actions): Remove dead code.
15481 2001-12-27 Akim Demaille <akim@epita.fr>
15483 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
15486 2001-12-27 Akim Demaille <akim@epita.fr>
15488 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
15489 (build_relations): Adjust.
15491 2001-12-27 Akim Demaille <akim@epita.fr>
15493 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
15496 2001-12-27 Akim Demaille <akim@epita.fr>
15498 * src/reader.c (packgram): Catch nitems overflows.
15500 2001-12-27 Akim Demaille <akim@epita.fr>
15502 * src/files.c, src/files.h (guard_obstack): Remove.
15503 * src/output.c (output): Adjust.
15504 * src/reader.c (parse_braces): New, factoring...
15505 (copy_action, copy_guard): these two which are renamed as...
15506 (parse_action, parse_guard): these.
15507 As a voluntary consequence, using braces around guards is now
15510 2001-12-27 Akim Demaille <akim@epita.fr>
15512 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
15513 * src/reader.c (symbol_list): `guard' and `guard_line' are new
15515 (symbol_list_new): Adjust.
15516 (copy_action): action_line is the first line, not the last.
15517 (copy_guard): Just as for actions, store the `action' only, not
15518 the switch/case/break flesh.
15519 Don't parse the user action that might follow the guard, let...
15520 (readgram): do it, i.e., now, there can be an action after a
15522 In other words the guard is just explicitly optional.
15523 (packgram): Adjust.
15524 * src/output.c (guards_output): New.
15525 (output_parser): Call it when needed.
15526 (output): Also free the guard and attrs obstacks.
15527 * src/files.c, src/files.h (obstack_save): Remove.
15528 (output_files): Remove.
15529 As a result, if one needs the former `.act' file, using an
15530 appropriate skeleton which requires actions and guards is now
15532 * src/main.c (main): Adjust.
15533 * tests/semantic.at: New.
15534 * tests/regression.at: Use `input.y' as input file name.
15535 Avoid 8+3 problems by requiring input.c when the test needs the

15540 * src/reader.c (symbol_list_new): Be sure to initialize all the
15543 2001-12-27 Akim Demaille <akim@epita.fr>
15545 All the hacks using a final pseudo state are now useless.
15547 * src/LR0.c (set_state_table): state_table holds exactly nstates.
15548 * src/lalr.c (nLA): New.
15549 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
15550 instead of lookaheadsp from the pseudo state (nstate + 1).
15552 2001-12-27 Akim Demaille <akim@epita.fr>
15554 * src/output.c (action_row, token_actions): Use a state_t instead
15555 of a integer, and nlookaheads instead of the following state's

15562 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
15563 (conflicts_print, print_reductions): Use a state_t instead of an
15564 integer when referring to a state.
15565 As much as possible, depend upon nlookaheads, instead of the
15566 `lookaheadsp' member of the following state (since lookaheads of
15567 successive states are successive, the difference between state n + 1
15568 and n served as the number of lookaheads for state n).
15569 * src/lalr.c (add_lookback_edge): Likewise.
15570 * src/print.c (print_core, print_actions, print_state)
15571 (print_results): Likewise.

15580 Remove `register' indications.
15581 Add plenty of `static'.
15583 2001-12-27 Akim Demaille <akim@epita.fr>
15585 * src/output.c (prepare): Drop the muscle `ntbase' which
15586 duplicates ntokens.
15587 * src/bison.simple: Formatting/comment changes.
15588 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
15589 is an undocumented synonym.
15591 2001-12-22 Akim Demaille <akim@epita.fr>
15593 * src/output.c (output_table_data): Change the prototype to use
15594 `int' for array ranges: some invocations do pass an int, not a
15596 Reported by Wayne Green.
15598 2001-12-22 Akim Demaille <akim@epita.fr>
15600 Some actions of web2c.y are improperly triggered.

15605 (Web2c Report): this.
15606 (Web2c Actions): New.
15608 2001-12-22 Akim Demaille <akim@epita.fr>
15610 Reductions in web2c.y are improperly reported.

15614 * tests/regression.at (Web2c): New.
15616 2001-12-18 Akim Demaille <akim@epita.fr>
15618 Some host fail on `assert (!"foo")', which expands to
15619 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
15620 Reported by Nelson Beebee.
15622 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
15623 `#define it_succeeded 0' and `assert (it_succeeded)'.
15625 2001-12-17 Marc Autret <autret_m@epita.fr>
15627 * src/bison.simple: Don't hard code the skeleton line and filename.
15628 * src/output.c (output_parser): Rename 'line' as 'output_line'.
15629 New line counter 'skeleton_line' (skeleton-line muscle).
15631 2001-12-17 Paul Eggert <eggert@twinsun.com>
15633 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
15634 YYDEBUG must be defined to a nonzero value.
15636 * src/bison.simple (yytname): Do not assume that the user defines
15637 YYDEBUG to a properly parenthesized expression.
15639 2001-12-17 Akim Demaille <akim@epita.fr>
15641 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
15642 nlookaheads is a new member.
15644 * src/lalr.h (nlookaheads): Remove this orphan declaration.
15645 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
15648 2001-12-17 Akim Demaille <akim@epita.fr>
15650 * src/files.h, src/files.c (open_files, close_files): Remove.
15651 * src/main.c (main): Don't open/close files, nor invoke lex_free,
15653 * src/reader.c (reader): Do it.
15655 2001-12-17 Akim Demaille <akim@epita.fr>
15657 * src/conflicts.c (print_reductions): Formatting changes.
15659 2001-12-17 Akim Demaille <akim@epita.fr>
15661 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
15662 (flush_reduce): New.
15663 (resolve_sr_conflict): Adjust.
15665 2001-12-17 Akim Demaille <akim@epita.fr>
15667 * src/output.c (output_obstack): Be static and rename as...
15668 (format_obstack): this, to avoid any confusion with files.c's
15670 * src/reader.h (muscle_obstack): Move to...
15671 * src/output.h: here, since it's defined in output.c.
15673 2001-12-17 Akim Demaille <akim@epita.fr>
15675 * src/output.c (action_row, save_column, default_goto)
15676 (sort_actions, matching_state, pack_vector): Better variable
15679 2001-12-17 Akim Demaille <akim@epita.fr>
15681 * src/output.c: Various formatting changes.
15683 2001-12-17 Akim Demaille <akim@epita.fr>
15685 * src/files.c (output_files): Free the output_obstack.
15686 * src/main.c (main): Call print and print_graph conditionally.
15687 * src/print.c (print): Work unconditionally.
15688 * src/print_graph.c (print_graph): Work unconditionally.
15689 * src/conflicts.c (log_resolution): Output only if verbose_flag.
15691 2001-12-16 Marc Autret <autret_m@epita.fr>
15693 * src/output.c (actions_output): Fix. When we use %no-lines,
15694 there is one less line per action.
15696 2001-12-16 Marc Autret <autret_m@epita.fr>
15698 * src/bison.simple: Remove a useless #line directive.
15699 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
15700 * src/output.c (get_lines_number): New.
15701 (output_parser): Adjust, now takes care about the lines of a
15703 Fix line numbering.
15704 (actions_output): Computes the number of lines taken by actions.
15705 (output_master_parser): Insert new skeleton which is the name of
15706 the output parser file name.
15708 2001-12-15 Marc Autret <autret_m@epita.fr>
15710 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
15712 2001-12-15 Marc Autret <autret_m@epita.fr>
15714 * src/output.c (output_gram): Keep track of the hairy one.
15716 2001-12-15 Akim Demaille <akim@epita.fr>
15718 Make `make distcheck' work.
15720 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
15721 system.h which uses libgettext.h.
15723 2001-12-15 Akim Demaille <akim@epita.fr>
15725 * src/nullable.c (set_nullable): Useless rules must be skipped,
15726 otherwise, since we range over their symbols, we might look at a
15727 nonterminal which no longer ``exists'', i.e., it is not counted in
15728 `nvars', hence we overflow our arrays.
15730 2001-12-15 Akim Demaille <akim@epita.fr>
15732 The header can also be produced directly, without any obstack!
15735 * src/files.c, src/files.h (defines_obstack): Remove.
15736 (compute_header_macro): Global.
15737 (defines_obstack_save): Remove.
15738 * src/reader.c (parse_union_decl): No longer output to
15739 defines_obstack: its content can be found in the `stype' muscle
15741 (output_token_translations): Merge into...
15742 (symbols_output): this.
15744 (symbols_save): this.
15746 * src/output.c (header_output): New.
15749 2001-12-15 Akim Demaille <akim@epita.fr>
15751 * src/reader.c (parse_union_decl): Instead of handling two obstack
15752 simultaneously, use one to define the `stype' muscle, and use the
15753 value of the latter to fill defines_obstack.
15754 (copy_comment): Remove.
15755 (copy_comment2): Work for a single obstack.
15757 (copy_comment): this.
15759 2001-12-15 Akim Demaille <akim@epita.fr>
15761 * src/lex.c, src/lex.h (xgetc): No longer static.
15762 * src/reader.c (parse_union_decl): Revamp.
15764 2001-12-15 Akim Demaille <akim@epita.fr>
15766 Still making progress in separating Bison into (i) input, (ii)
15767 process, (iii) output: now we can directly output the parser file
15768 without using table_obstack at all.
15770 * src/files.c, src/files.h (table_obstack): Bye bye.
15771 (parser_file_name): New.
15772 * src/files.c (compute_output_file_names): Compute it.
15773 * src/output.c (actions_output, output_parser)
15774 (output_master_parser): To a file instead of an obstack.
15776 2001-12-15 Akim Demaille <akim@epita.fr>
15778 Attach actions to rules, instead of pre-outputting them to
15781 * src/gram.h (rule_t): action and action_line are new members.
15782 * src/reader.c (symbol_list): Likewise.
15783 (copy_action): Save the actions within the rule.
15784 (packgram): Save them in rule_table.
15785 * src/output.c (actions_output): New.
15786 (output_parser): Use it on `%%actions'.
15787 (output_rule_data): Don't free rule_table.
15789 (prepare): Don't save the `action' muscle.
15790 * src/bison.simple: s/%%action/%%actions/.
15792 2001-12-15 Akim Demaille <akim@epita.fr>
15794 * src/reader.c (copy_action): When --yacc, don't append a `;'
15795 to the user action: let it fail if lacking.
15796 Suggested by Arnold Robbins and Tom Tromey.
15798 2001-12-14 Akim Demaille <akim@epita.fr>
15800 * src/lex.c (literalchar): Simply return the char you decoded, non
15801 longer mess around with obstacks and int pointers.
15802 Adjust all callers.
15804 2001-12-14 Akim Demaille <akim@epita.fr>
15806 * src/lex.c (literalchar): Don't escape the special characters,
15807 just decode them, and keep them as char (before, eol was output as
15808 the 2 char string `\n' etc.).
15809 * src/output.c (output_rule_data): Use quotearg to output the
15812 2001-12-13 Paul Eggert <eggert@twinsun.com>
15814 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
15815 Do not infringe on the global user namespace when using C++.
15816 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
15817 All uses of `fprintf' and `stderr' changed.
15819 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
15821 2001-12-13 Akim Demaille <akim@epita.fr>
15823 The computation of nullable is broken: it doesn't handle empty
15826 * tests/torture.at (GNU AWK Grammar): New.
15827 * tests/sets.at (Nullable): New.
15828 * src/nullable.c (set_nullable): Instead of blindly looping over
15829 `ritems', loop over the rules, and then over their rhs's.
15831 Work around Autotest bugs.
15833 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
15834 frame, because Autotest understand lines starting with a `+' as
15835 traces from the shell. Then, they are not processed properly.
15836 Admittedly an Autotest bug, but we don't have time to wait for
15837 Autotest to catch up.
15838 * tests/regression.at (Broken Closure): Adjust to the new table
15841 * tests/sets.at: here.
15843 2001-12-13 Akim Demaille <akim@epita.fr>
15845 * src/closure.c (closure): Use nrules instead of playing tricks
15846 with BITS_PER_WORD.
15848 2001-12-13 Akim Demaille <akim@epita.fr>
15850 * src/print.c (print_actions): Output the handling of `$' as the
15851 traces do: shifting the token EOF. Before EOF was treated as a
15853 * tests/regression.at: Adjust some tests.
15854 * src/print_graph.c (print_core): Complete the set of items via
15855 closure. The next-to-final and final states are still unsatisfying,
15856 but that's to be addressed elsewhere.
15857 No longer output the rule numbers, but do output the state number.
15858 A single loop for the shifts + gotos is enough, but picked a
15859 distinct color for each.
15860 (print_graph): Initialize and finalize closure.
15862 2001-12-13 Akim Demaille <akim@epita.fr>
15864 * src/reader.c (readgram): Remove dead code, an strip useless
15866 (get_type): Remove, unused.
15868 2001-12-12 Akim Demaille <akim@epita.fr>
15870 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
15871 on that of lib/error.c.
15873 2001-12-12 Akim Demaille <akim@epita.fr>
15875 Some hosts don't like `/' in includes.
15877 * src/system.h: Include libgettext.h without qualifying the path.
15878 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
15881 2001-12-11 Marc Autret <autret_m@epita.fr>
15883 * src/output.c (output_parser): Remove useless muscle.
15885 2001-12-11 Marc Autret <autret_m@epita.fr>
15887 * src/bison.simple: Remove #line just before %%epilogue. It
15888 is now handled in ...
15889 * src/reader.c (read_additionnal_code): Add the output of a
15890 #line for the epilogue.
15892 2001-12-10 Marc Autret <autret_m@epita.fr>
15894 * src/reader.c (copy_definition): Re-use CPP-outed code which
15895 replace precedent remove.
15896 * src/bison.simple: Remove #line before %%prologue because
15897 %%input-line is wrong at this time.
15899 2001-12-10 Marc Autret <autret_m@epita.fr>
15901 * src/reader.c (symbols_output): Clean up.
15902 * src/output.c (output_gram, output): Clean up.
15904 2001-12-10 Akim Demaille <akim@epita.fr>
15906 * src/lalr.c (initialize_lookaheads): New. Extracted from...
15907 * src/LR0.c (set_state_table): here.
15908 * src/lalr.c (lalr): Call it.
15910 2001-12-10 Akim Demaille <akim@epita.fr>
15912 * src/state.h (shifts): Remove the `number' member: shifts are
15913 attached to state, hence no longer need to be labelled with a
15916 2001-12-10 Akim Demaille <akim@epita.fr>
15918 Now that states have a complete set of members, the linked list of
15919 shifts is useless: just fill directly the state's shifts member.
15921 * src/state.h (shifts): Remove the `next' member.
15922 * src/LR0.c (first_state, last_state): Remove.
15923 Adjust the callers.
15924 (augment_automaton): Don't look for the shifts that must be added
15925 a shift on EOF: it is those of the state we looked for! But now,
15926 since shifts are attached, it is no longer needed to looking
15927 merely by its id: its number.
15929 2001-12-10 Akim Demaille <akim@epita.fr>
15931 * src/LR0.c (augment_automaton): Better variable locality.
15932 Remove an impossible branch: if there is a state corresponding to
15933 the start symbol being shifted, then there is shift for the start
15934 symbol from the initial state.
15936 2001-12-10 Akim Demaille <akim@epita.fr>
15938 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
15939 only when appropriate: when insert_start_shifting_state' is not
15941 * tests/regression.at (Rule Line Numbers): Adjust.
15943 2001-12-10 Akim Demaille <akim@epita.fr>
15945 * src/LR0.c (augment_automaton): Now that all states have shifts,
15946 merge the two cases addition shifts to the initial state.
15948 2001-12-10 Akim Demaille <akim@epita.fr>
15950 * src/lalr.c (set_state_table): Move to...
15952 * src/lalr.c (lalr): Don't call it...
15953 * src/LR0.c (generate_states): do it.
15954 * src/LR0.h (first_state): Remove, only the table is used.
15956 2001-12-10 Akim Demaille <akim@epita.fr>
15958 * src/LR0.h (first_shift, first_reduction): Remove.
15959 * src/lalr.c: Don't use first_shift: find shifts through the
15962 2001-12-10 Akim Demaille <akim@epita.fr>
15964 * src/LR0.c: Attach shifts to states as soon as they are
15966 * src/lalr.c (set_state_table): Instead of assigning shifts to
15967 state, just assert that the mapping was properly done.
15969 2001-12-10 Akim Demaille <akim@epita.fr>
15971 * src/LR0.c (insert_start_shift): Rename as...
15972 (insert_start_shifting_state): this.
15973 (insert_eof_shifting_state, insert_accepting_state): New.
15974 (augment_automaton): Adjust.
15975 Better locality of the variables.
15976 When looking if the start_symbol is shifted from the initial
15977 state, using `while (... symbol != start_symbol ...)' sounds
15978 better than `while (... symbol < start_symbol ...)': If fail
15979 to see how the order between symbols could be relevant!
15981 2001-12-10 Akim Demaille <akim@epita.fr>
15983 * src/getargs.h: Don't declare `spec_name_prefix' and
15984 `spec_file_prefix', declared by src/files.h.
15985 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
15986 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
15987 * src/output.c (prepare): Adjust.
15988 * src/reader.c (symbols_output): Likewise.
15989 * src/vmsgetargs.c: Vaguely adjust, but who cares?
15991 2001-12-10 Akim Demaille <akim@epita.fr>
15993 * src/muscle_tab.c (muscle_init): NULL is a better default than
15996 2001-12-10 Akim Demaille <akim@epita.fr>
15998 * src/reader.c (reader): Calling symbols_output once is enough.
16000 2001-12-10 Akim Demaille <akim@epita.fr>
16002 Now that states have a complete set of members, the linked list of
16003 reductions is useless: just fill directly the state's reductions
16006 * src/state.h (struct reductions): Remove member `number' and
16008 * src/LR0.c (first_reduction, last_reduction): Remove.
16009 (save_reductions): Don't link the new reductions, store them in
16011 * src/lalr.c (set_state_table): No need to attach reductions to
16012 states, it's already done.
16013 * src/output.c (output_actions): No longer free the shifts, then
16014 the reductions, then the states: free all the states and their
16017 2001-12-10 Akim Demaille <akim@epita.fr>
16019 * src/options.c (OPTN, DRTV, BOTH): New.
16020 (option_table): Use them.
16022 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
16023 the job of system.h.
16024 * src/options.c: Don't include stdio.h and xalloc.h for the same
16027 2001-12-10 Akim Demaille <akim@epita.fr>
16029 * src/output.c (output, prepare): Make sure the values of the
16030 muscles `action' and `prologue' are 0-terminated.
16032 2001-12-10 Akim Demaille <akim@epita.fr>
16034 Clean up GCC warnings.
16036 * src/reader.c (copy_action): `buf' is not used.
16037 (parse_skel_decl): Be static.
16038 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
16039 * src/options.h (create_long_option_table): Have a real prototype.
16040 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
16041 (hash_delete_at): Return const void *.
16042 Adjust casts to preserve the const.
16044 2001-12-10 Akim Demaille <akim@epita.fr>
16046 * configure.in: Require 2.52g.
16047 M4 is not needed, but AUTOM4TE is.
16048 * m4/m4.m4: Remove.
16049 * tests/Makefile.am: Adjust.
16051 2001-12-10 Akim Demaille <akim@epita.fr>
16053 One structure for states is enough, even though theoretically
16054 there are LR(0) states and LALR(1) states.
16056 * src/lalr.h (state_t): Remove.
16057 (state_table): Be state_t **, not state_t *.
16058 * src/state.h (core, CORE_ALLOC): Rename as...
16059 (state_t, STATE_ALLOC): this.
16060 Add the LALR(1) members: shifts, reductions, errs.
16061 * src/LR0.c (state_table): Rename as...
16062 (state_hash): this, to avoid name clashes with the global
16064 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
16065 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
16067 2001-12-10 Akim Demaille <akim@epita.fr>
16069 Bison dumps core on bash.y.
16070 Reported by Pascal Bart.
16072 * src/warshall.c (bitmatrix_print): New.
16074 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
16075 j must be the outer loop.
16076 * tests/regression.at (Broken Closure): New.
16078 2001-12-05 Akim Demaille <akim@epita.fr>
16080 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
16082 Reported by Peter Hamorsky.
16084 2001-12-05 Akim Demaille <akim@epita.fr>
16086 * src/conflicts.c (err_table): Remove.
16087 (resolve_sr_conflict): Adjust.
16088 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
16090 (state_t.reductions, state_t.shifts): this.
16092 2001-12-05 Akim Demaille <akim@epita.fr>
16094 * src/reduce.c (reduce_grammar_tables): No longer disable the
16095 removal of useless rules via CPP but via `if (0)', so that the
16096 compiler still check the code is valid.
16097 For instance, it should have noticed `rline' no longer exists: use
16098 the `line' member of rule_t.
16099 * src/gram.c (dummy, rline): Remove, unused.
16101 2001-12-05 Akim Demaille <akim@epita.fr>
16103 * src/output.c (pack_vector): Use assert, not berror.
16104 * src/main.c (berror): Remove, unused.
16106 2001-12-05 Akim Demaille <akim@epita.fr>
16108 New experimental feature: if --verbose --trace output all the
16109 items of a state, not only its kernel.
16111 * src/print.c (print_core): If `trace_flag', then invoke closure
16112 before outputting the items of the state (print_core is no longer
16113 a correct name them).
16114 (print_results): Invoke new_closure/free_closure if needed.
16116 2001-12-05 Akim Demaille <akim@epita.fr>
16118 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
16119 * src/closure.c, src/closure.h (itemsetsize): Rename as...
16120 (nitemset): for consistency with the rest of the project.
16122 2001-12-05 Akim Demaille <akim@epita.fr>
16124 * src/closure.c (print_closure): Improve.
16125 (closure): Use it for printing input and output.
16127 2001-12-05 Akim Demaille <akim@epita.fr>
16129 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are

16154 locality, BITISSET, RESETBIT etc.
16156 2001-12-05 Akim Demaille <akim@epita.fr>
16158 Pessimize the code to simplify it: from now on, all the states
16159 have a valid SHIFTS, which NSHIFTS is possibly 0.
16161 * src/LR0.c (shifts_new): Be global and move to..
16162 * src/state.c, src/state.h: here.
16163 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

16175 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
16176 using the good o' techniques: arrays not pointers, variable
16177 locality, BITISSET, RESETBIT etc.
16179 2001-12-05 Akim Demaille <akim@epita.fr>
16181 * src/state.h (SHIFT_SYMBOL): New.

16211 2001-12-05 Akim Demaille <akim@epita.fr>
16213 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

16229 * src/lalr.c (maxrhs): Move to...
16230 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
16231 * src/lalr.c (build_relations): Adjust.
16233 2001-12-05 Akim Demaille <akim@epita.fr>
16235 * src/lalr.c (transpose): Free the memory allocated to the
16236 argument, as it is replaced by the results by the unique caller.
16237 (build_relations): Merely invoke transpose: it handles the memory
16239 Improve variable locality.
16240 Avoid variables used as mere abbreviations.
16241 (compute_lookaheads): Use arrays instead of pointers.
16243 2001-12-05 Akim Demaille <akim@epita.fr>
16245 * src/lalr.c (initialize_F): Improve variable locality.
16246 Avoid variables used as mere abbreviations.

16259 2001-12-05 Akim Demaille <akim@epita.fr>
16261 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
16262 the handling of squeue.
16263 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16265 2001-12-05 Akim Demaille <akim@epita.fr>
16267 Because useless nonterminals are now kept alive (instead of being
16268 `destroyed'), we now sometimes examine them, and store information
16269 related to them. Hence we need to know their number, and adjust
16270 memory allocations.
16272 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
16274 * src/LR0.c (allocate_itemsets): The memory allocated to
16275 `symbol_count' was used for two different purpose: once to count
16276 the number of occurrences of each symbol, and later reassigned to
16277 `shift_symbol', containing the symbol that can be shifted from a
16279 Deobfuscate, i.e., allocate, use and free `symbol_count' here
16281 (new_itemsets): Allocate `shift_symbol' here.
16282 (allocate_itemsets): symbol_count includes useless nonterminals.
16283 Make room for them.
16284 (free_storage): Use `free', not `XFREE', for pointers that cannot
16287 2001-12-05 Akim Demaille <akim@epita.fr>

16293 2001-12-05 Akim Demaille <akim@epita.fr>
16295 * src/gram.c, src/gram.h (ritem_print): New.
16296 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
16297 (This useless function was defined only to work around VMS linkers
16298 that can't handle compilation units with variables only).
16299 * src/reduce.c (dump_grammar): Use it to trace the construction of
16302 2001-12-04 Paul Eggert <eggert@twinsun.com>
16304 * src/bison.simple (union yyalloc): Change member names
16305 to be the same as the stack names.
16306 (yyparse): yyptr is now union yyalloc *, not char *.
16307 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
16308 and may generate better code on some machines.
16309 (yystpcpy): Use prototype if __STDC__ is defined, not just
16310 if __cplusplus is defined.
16312 2001-11-30 Akim Demaille <akim@epita.fr>
16314 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
16315 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
16316 Gettext doesn't compile cleanly, and dies with -Werror.
16317 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
16318 Include WARNING_CFLAGS here.
16319 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
16320 before being defined.
16322 2001-11-27 Paul Eggert <eggert@twinsun.com>
16324 * lib/quotearg.h (quotearg_n, quotearg_n_style):
16325 First arg is int, not unsigned.
16326 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
16327 (SIZE_MAX, UINT_MAX): New macros.
16328 (quotearg_n_options): Abort if N is negative.
16329 Avoid overflow check on hosts where size_t is 64 bits and int
16330 is 32 bits, as overflow is impossible there.
16331 Fix off-by-one typo that caused unnecessary reallocation.
16333 2001-11-29 Paul Eggert <eggert@twinsun.com>
16335 Name space cleanup in generated parser.
16337 * doc/bison.texinfo (Bison Parser): Discuss system headers
16338 and their effect on the user name space.
16340 * src/bison.simple:
16341 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
16342 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
16343 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
16345 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
16346 on user names when possible.
16348 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
16349 Simplify test for whather <alloca.h> exists.
16351 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
16353 (<stdio.h>): Include if YYDEBUG.
16355 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
16356 ! defined (yyoverflow) && ! defined (yymemcpy).
16358 (yymemcpy, yyparse): Rename local variables as needed so that
16359 they all begin with 'yy'.
16361 (yystrlen, yystpcpy): New functions.
16363 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
16366 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
16367 instead of relying on string.h functions. Use YYSTACK_ALLOC
16368 and YYSTACK_FREE instead of malloc and free.
16370 2001-11-30 Akim Demaille <akim@epita.fr>
16372 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
16373 before their first uses.

16380 2001-11-30 Akim Demaille <akim@epita.fr>

16383 if body instead of `;' to pacify GCC's warnings.
16385 2001-11-30 Akim Demaille <akim@epita.fr>
16387 Instead of mapping the LHS of unused rules to -1, keep the LHS
16388 valid, but flag the rules as invalid.
16390 * src/gram.h (rule_t): `useful' is a new member.
16391 * src/print.c (print_grammar): Adjust.
16392 * src/derives.c (set_derives): Likewise.
16393 * src/reader.c (packgram, reduce_output): Likewise.
16394 * src/reduce.c (reduce_grammar_tables): Likewise.
16395 * tests/reduce.at (Underivable Rules, Useless Rules): New.
16397 2001-11-30 Akim Demaille <akim@epita.fr>

16404 2001-11-30 Akim Demaille <akim@epita.fr>
16406 * src/reduce.c (nonterminals_reduce): Instead of throwing away
16407 useless nonterminals, move them at the end of the symbol arrays.
16408 (reduce_output): Adjust.
16409 * tests/reduce.at (Useless Nonterminals): Adjust.
16411 2001-11-30 Akim Demaille <akim@epita.fr>

16421 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
16422 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
16424 (union yyalloc): New type.
16425 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
16426 an arbitrary restriction on hosts where size_t is wider than int.
16428 (yyparse): Don't dump core if alloca or malloc fails; instead, report
16429 a parser stack overflow. Allocate just one block of memory for all
16430 three stacks, instead of allocating three blocks; this typically is
16431 faster and reduces fragmentation.
16433 Do not limit the number of items in the stack to a value that fits
16434 in 'int', as this is an arbitrary limit on hosts with 64-bit
16435 size_t and 32-bit int.
16437 2001-11-29 Marc Autret <autret_m@epita.fr>
16439 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
16440 of defining YYERROR_VERBOSE.
16441 [AT_DATA]: $4 is now out of C declarations in the prologue.
16443 2001-11-28 Marc Autret <autret_m@epita.fr>

16487 * src/closure.c (closure): `b' and `ruleno' denote the same value:
16490 2001-11-28 Akim Demaille <akim@epita.fr>
16492 * src/closure.c (closure): Instead of looping over word in array
16493 then bits in words, loop over bits in array.
16495 2001-11-28 Akim Demaille <akim@epita.fr>
16497 * src/closure.c (closure): No longer optimize the special case
16498 where all the bits of `ruleset[r]' are set to 0, to make the code
16501 2001-11-28 Akim Demaille <akim@epita.fr>
16503 * src/closure.c (closure): `r' and `c' are new variables, used to
16504 de-obfuscate accesses to RULESET and CORE.
16506 2001-11-28 Akim Demaille <akim@epita.fr>
16508 * src/reduce.c (reduce_print): Use ngettext.

16513 * src/reduce.c (dump_grammar): Don't translate trace messages.
16515 2001-11-28 Akim Demaille <akim@epita.fr>
16517 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
16518 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
16519 as all tags are free'ed afterwards.
16520 From Enrico Scholz.
16522 2001-11-27 Paul Eggert <eggert@twinsun.com>
16524 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
16525 use alloca when we didn't want to, and vice versa.

16608 * src/conflicts.c (conflicts_print): Don't complain at all when
16609 there are no reduce/reduce conflicts, and as many shift/reduce
16610 conflicts as expected.
16611 * tests/regression.at (%expect right): Adjust.
16613 2001-11-23 Akim Demaille <akim@epita.fr>
16615 * lib/alloca.c: Update, from fileutils.

16634 2001-11-23 Akim Demaille <akim@epita.fr>
16636 Attaching lineno to buckets is stupid, since only one copy of each

16640 * src/reader.c (rline_allocated): Remove, unused.

18204 2001-07-14 Akim Demaille <akim@epita.fr>
18207 * configure.in: Require Autoconf 2.50.

18240 * src/conflicts.c (conflict_report): Be sure not to append to res
18241 between two calls, which could happen if both first sprintf were
18242 skipped, but not the first cp += strlen.
18244 2001-02-08 Akim Demaille <akim@epita.fr>
18246 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
18247 New, from fileutils 4.0.37.
18248 * configure.in: Require Autoconf 2.49c. I took some time before
18249 making this decision. This is the only way out for portability
18250 issues in Bison, it would mean way too much duplicate effort to
18251 import in Bison features implemented in 2.49c since 2.13.
18252 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
18254 2001-02-02 Akim Demaille <akim@epita.fr>

18271 * src/lex.h: Rename all the tokens:
18272 s/\bENDFILE\b/tok_eof/g;
18273 s/\bIDENTIFIER\b/tok_identifier/g;
18275 Let them be enums, not #define, to ease debugging.

18293 * src/reader.c (read_declarations): Adjust.
18294 * src/files.c (open_files): Don't call `compute_base_names', don't

18298 * src/output.c (output_headers): Document the fact that this patch
18299 introduces a guaranteed SEGV for semantic parsers.
18300 * doc/bison.texinfo: Document them.
18301 * tests/suite.at: Exercise these %options.
18303 2000-12-20 Akim Demaille <akim@epita.fr>

18315 2000-12-20 Akim Demaille <akim@epita.fr>
18317 * src/files.c (open_files): Fix the computation of short_base_name
18318 in the case of `-o foo.tab.c'.

18326 2000-12-20 Akim Demaille <akim@epita.fr>
18328 * src/files.c (open_files): Actually the `.output' file is based

18368 (obstack_grow_string): this.
18369 * src/output.c (output_parser): Recognize `%% actions' instead of
18371 * src/bison.s1: s/$/%% actions/.
18372 * src/bison.hairy: Likewise.
18374 2000-12-19 Akim Demaille <akim@epita.fr>
18376 * src/output.c (output_parser): Compute the `#line' lines when
18378 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

18403 * src/files.c (open_files): Yipee! We no longer need all the code

18408 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

18435 * lib/obstack.h: Formatting changes.
18436 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
18437 prevents type checking.
18438 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

18461 Use them to declare the variables which are global or local to
18464 2000-11-17 Akim Demaille <akim@epita.fr>
18466 * acconfig.h: Remove, no longer used.
18468 2000-11-07 Akim Demaille <akim@epita.fr>
18470 * src: s/Copyright (C)/Copyright/g.
18472 2000-11-07 Akim Demaille <akim@epita.fr>
18474 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
18476 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

18492 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
18493 `const' their input argument (`data' or `address').
18494 Adjust the corresponding macros to include `const' in casts.
18496 2000-11-03 Akim Demaille <akim@epita.fr>
18498 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
18499 s/PFILE1/BISON_HAIRY/.
18500 Adjust dependencies.
18502 2000-11-03 Akim Demaille <akim@epita.fr>
18504 For some reason, this was not applied.
18506 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
18507 `unlink': it's no longer used.
18509 2000-11-03 Akim Demaille <akim@epita.fr>
18511 * src/files.c (skeleton_find): New function, eved out of...

18516 Don't use `atexit'.
18518 * src/files.c (obstack_save): New function.
18519 (done): Rename as...
18520 (output_files): this.
18521 Use `obstack_save'.
18522 * src/main.c (main): Don't use `atexit' to register `done', since
18523 it no longer has to remove tmp files, just call `output_files'
18524 when there are no errors.
18526 2000-11-02 Akim Demaille <akim@epita.fr>
18528 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
18529 `unlink': it's no longer used.
18530 * src/files.h: Formatting changes.
18532 2000-11-02 Akim Demaille <akim@epita.fr>
18534 Remove the last uses of mktemp and unlink/delete.
18536 * src/files.c (fdefines, ftable): Removed.
18537 (defines_ostack, table_obstack): New.
18538 Adjust dependencies of the former into uses of the latter.
18539 * src/output.c (output_short_or_char_table, output_short_table):

18596 * src/reader.c (copy_comment2): Expect the input stream to be on
18597 the `/' which is suspected to open a comment, instead of being
18598 called after `//' or `/*' was read.
18599 (copy_comment, copy_definition, parse_union_decl, copy_action)
18600 (copy_guard): Adjust.
18602 2000-10-16 Akim Demaille <akim@epita.fr>
18604 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
18605 `read_signed_integer'.
18607 2000-10-16 Akim Demaille <akim@epita.fr>
18609 * src/reader.c (copy_dollar): New function.
18610 (copy_guard, copy_action): Use it.
18612 2000-10-16 Akim Demaille <akim@epita.fr>
18614 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
18615 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
18616 New files, from Fileutils 4.0.27.
18617 * src/main.c (printable_version): Remove.
18618 * src/lex.c, src/reader.c: Use `quote'.
18620 2000-10-04 Akim Demaille <akim@epita.fr>
18622 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
18624 2000-10-04 Akim Demaille <akim@epita.fr>
18626 * doc/bison.texinfo: Various typos spotted by Neil Booth.
18628 2000-10-04 Akim Demaille <akim@epita.fr>
18630 When a literal string is used to define two different tokens,
18631 `bison -v' segfaults.
18632 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
18634 * tests/regression.m4: New file.
18635 Include the core of the sample provided by Piotr Gackiewicz.
18636 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
18639 2000-10-04 Akim Demaille <akim@epita.fr>
18641 * src/reader.c (parse_expect_decl): Keep `count' within the size
18645 2000-10-02 Paul Eggert <eggert@twinsun.com>
18647 * bison.s1 (yyparse): Assign the default value
18648 unconditionally, to avoid a GCC warning and make the parser a
18651 2000-10-02 Akim Demaille <akim@epita.fr>
18653 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
18656 2000-10-02 Akim Demaille <akim@epita.fr>
18658 * src/derives.c, src/print.c, src/reduce.c: To ease the
18659 translation, move some `\n' out of the translated strings.
18661 2000-10-02 Akim Demaille <akim@epita.fr>
18663 The location tracking mechanism is precious for parse error
18664 messages. Nevertheless, it is enabled only when `@n' is used in
18665 the grammar, which is a different issue (you can use it in error
18666 message, but not in the grammar per se). Therefore, there should
18667 be another means to enable it.
18669 * src/getargs.c (getargs): Support `--locations'.
18670 (usage): Report it.
18671 * src/getargs.h (locationsflag): Export it.
18672 * src/lex.c (percent_table): Support `%locations'.
18673 * src/reader.c (yylsp_needed): Remove this variable, now replaced
18674 with `locationsflag'.
18675 * doc/bison.texinfo: Document `--locations' and `%locations'.
18677 * tests/calc.m4: Test it.
18679 For regularity of the names, replace each
18680 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
18681 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
18682 In addition replace each `flag' with `_flag'.
18684 2000-10-02 Akim Demaille <akim@epita.fr>
18686 Also test parse error messages, including with YYERROR_VERBOSE.
18688 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
18690 Use it to check the computations.
18691 Use it to check `nonassoc' is honored.
18692 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
18693 `--yyerror-verbose'.
18694 (_AT_CHECK_CALC): Adjust to this option.
18695 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
18697 2000-10-02 Akim Demaille <akim@epita.fr>
18699 Test also `--verbose', `--defines' and `--name-prefix'. Testing
18700 the latter demonstrates a flaw in the handling of non debugging
18701 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
18702 was used in order to simplify:
18718 unfortunately this leads to a CPP conflict when
18719 `--name-prefix=foo' is used since it produces `#define yydebug
18722 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
18723 (YYDPRINTF): New macro.
18725 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
18727 Also test `--verbose', `--defines' and `--name-prefix'.

18731 Improve the readability of the produced parsers.
18733 * src/bison.s1: Formatting changes.
18734 Improve the comment related to the `$' mark.
18735 (yydefault): Don't fall through to `yyresume': `goto' there.
18736 * src/output.c (output_parser): When the `$' is met, skip the end
18738 New variable, `number_of_dollar_signs', to check there's exactly
18739 one `$' in the parser skeleton.
18741 2000-10-02 Akim Demaille <akim@epita.fr>
18743 * lib/xstrdup.c: New file, from the fileutils.
18744 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
18745 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
18746 instead of strlen + xmalloc + strcpy.
18747 * src/symtab.c (copys): Remove, use xstrdup instead.
18749 2000-10-02 Akim Demaille <akim@epita.fr>
18751 * src/gram.h (associativity): New enum type which replaces the
18752 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
18753 `right_assoc', `left_assoc' and `non_assoc'.
18754 Adjust all dependencies.
18755 * src/reader.c: Formatting changes.
18756 (LTYPESTR): Don't define it, use it as a literal in
18757 `reader_output_yylsp'.
18758 * src/symtab.h (symbol_class): New enum type which replaces the
18759 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

18768 2000-10-02 Akim Demaille <akim@epita.fr>
18770 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
18771 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
18772 difficult and introduced a lot of core dump. It turns out that
18773 Bison used an implementation of `xmalloc' based on `calloc', and
18774 at various places it does depend upon the initialization to 0. I
18775 have not tried to isolate the pertinent places, and all the former
18776 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
18777 someone should address this issue.
18779 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
18780 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

18836 Propagate its inclusion.
18837 * src/reduce.c: Topological sort and other formatting changes.
18838 (bool, TRUE, FALSE): Move their definition to...

18874 * src/output.c (token_actions): Introduce a temporary array,
18875 YYDEFACT, that makes it possible for this function to use
18876 output_short_table.
18878 2000-10-02 Akim Demaille <akim@epita.fr>
18880 `user_toknums' is output as a `short[]' in `output.c', while it is
18881 defined as a `int[]' in `reader.c'. For consistency with the
18882 other output tables, `user_toknums' is now defined as a table of
18885 * src/reader.c (user_toknums): Be a short table instead of an int

18925 Don't define PARAMS.
18926 * src/system.h: Define PARAMS.
18927 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
18928 purpose of config.h. system.h must not try to fix wrong
18929 definitions in config.h.

19147 Change the handling of @s so that they behave exactly like $s.
19148 There is now a pseudo variable @$ (readble and writable), location
19149 of the lhs of the rule (by default ranging from the location of
19150 the first symbol of the rhs, to the location of the last symbol,
19151 or, if the rhs is empty, YYLLOC).
19153 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
19155 (yyparse): When providing a default semantic action, provide a
19156 default location action.

19158 same way you stack YYVAL.
19159 * src/reader.c (read_declarations): Use warns.
19160 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

19186 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

19869 % declarations as another means to specify the flags.
19870 (readgram): Allow %prec prior to semantics embedded in a rule.
19871 (skip_to_char, read_declarations, copy_definition)
19872 (parse_token_decl, parse_start_decl, parse_type_decl)
19873 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
19874 (get_type_name, copy_guard, copy_action, readgram)
19875 (get_type, packsymbols): Revised most error messages.
19876 Changed `fatal' to `warnxxx' to avoid aborting for error.
19877 Revised and use multiple warnxxx functions to avoid using VARARGS1.
19878 (read_declarations): Improve the error message for
19879 an invalid character. Do not abort.
19880 (read_declarations, copy_guard, copy_action): Use
19881 printable_version to avoid unprintable characters in printed output.
19882 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
19883 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
19884 Allow the type of a non-terminal can be given
19885 more than once, as long as all specifications give the same type.
19888 (output_headers, output_trailers, output, output_gram)
19889 (output_rule_data): Implement noparserflag variable.
19890 Implement toknumflag variable.
19891 (output): Call reader_output_yylsp to output LTYPESTR.
19893 * src/main.c (main):
19894 If reader sees an error, don't process the grammar.
19895 (fatals): Updated to not use VARARGS1.
19896 (printable_version, int_to_string, warn, warni, warns, warnss)
19897 (warnsss): New error reporting functions. Avoid abort for error.
19900 Added THONG and NOOP for alias processing.
19901 Added SETOPT for the new code that allows setting options with %flags.
19904 Include getopt.h. Add some extern decls.
19905 (safegetc): New function to deal with EOF gracefully.
19906 (literalchar); new function to deal with reading \ escapes.
19907 (lex): Use literalchar.
19908 (lex): Implemented "..." tokens.
19909 (literalchar, lex, parse_percent_token): Made tokenbuffer
19910 always contain the token. This includes growing the token
19911 buffer while reading an integer.
19912 (parse_percent_token): Replaced if-else statement with percent_table.
19913 (parse_percent_token): Added % declarations as another
19914 way to specify the flags -n, -l, and -r. Also added hooks for
19915 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
19916 major changes to files.c.
19917 (lex) Retain in the incoming stream a character following
19919 (skip_white_space, lex): Revised most error messages
19920 and changed fatal to warn to avoid aborting.
