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

525 (b4_percent_define_default): Record defining location as line 1 rather
526 than 0 for the sake of synchronizing #line's, and define
527 b4_percent_define_syncline(VARIABLE).
528 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
529 * src/muscle_tab.c (muscle_syncline_grow): New.

538 rather than 0 for the sake of synchronizing #line's, and define
539 b4_percent_define_syncline(VARIABLE).

541 muscle_percent_define_get_loc.
542 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
543 (muscle_percent_define_get_syncline): Prototype.

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

587 * src/reduce.c (reduce_xml): XML-escape terminal symbol tags.
589 2007-09-25 Joel E. Denny <jdenny@ces.clemson.edu>
591 Replace `%push-parser' and `%push-pull-parser' with

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

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

738 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
740 In impure push mode, don't allow more than one yypstate to be allocated
741 since multiple impure parsers would corrupt yynerrs.
742 * data/push.c (yypstate_allocated): New static global variable

826 * doc/bison.1: Likewise.
827 * doc/bison.texinfo (Decl Summary): Likewise.
828 (Bison Options): Likewise.

838 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
840 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
841 name user variables starting with `yy'. Just pass NULL instead of a
842 dummy local &yylval to yypush_parse.
843 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
846 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
848 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
849 true since it's then always used regardless of whether yyoverflow is
850 defined. Reported by Christian Burger at
851 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
852 * THANKS: Add Christian Burger.
854 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
855 node names: say "Decl Summary" not "Bison Declaration Summary".
857 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
859 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
860 determine whether this function has already complained about an invalid
861 value for a %define boolean variable, don't check whether Bison has
862 ever examined the value. As written, the check was a tautology.
863 Instead, record and check for this complaint using a separate muscle.
865 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
867 Fix push parsing memory leak reported by Brandon Lucia at
868 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
869 * THANKS: Add Brandon Lucia.
870 * data/push.c (yypstate_delete): Free the stack if it was reallocated
871 but the parse never completed and thus freed it.
872 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
873 * tests/testsuite.at: Include push.at.
875 (Push Parsing: Memory Leak for Early Deletion): New test case.

879 Improve handling of multiple S/R conflicts in the same state and of S/R
880 conflicts involving multiple reductions.
881 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
882 set for a state here or Bison will abort if it is reassigned on a
883 later conflicted reduction in the same state.
884 Similarly, don't finalize and assign the solved conflicts report here
885 or it will be lost if it is reassigned on a later conflicted reduction
887 (set_conflicts): Instead, assign them both here after all S/R conflicts
888 in the state have been fully examined.
889 * src/print.c (shift_set): Rename to...
890 (no_reduce_set): ... this.
891 (print_reductions): Update for rename, and add %nonassoc error action
892 tokens to no_reduce_set so that, when printing the first remaining
893 reduction on an error action token, the reduction is enclosed in
895 (print_results): Update for rename.
896 * tests/conflicts.at (Solved conflicts report for multiple reductions
897 in a state): New test case.
898 (%nonassoc error actions for multiple reductions in a state): New test
901 * src/main.c (main): Don't depend on C99 features.
903 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
905 * build-aux/.cvsignore: Add compile.
906 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
909 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
911 * bootstrap (slurp): Create target directories that don't exist.
912 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
914 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
916 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
918 * closure.c (closure): Likewise.
919 * state.h (reductions): Comment sorting of rules.
920 (state): Comment sorting of items.
922 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
924 Fix C++ test cases after recent Gnulib changes. Discussed starting at
925 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
926 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
927 definition in order to avoid Gnulib headers since we don't use config.h
929 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
930 rather than AT_DATA so that config.h is included.
932 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
934 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
935 instead of fprintf. Guard these functions with #if YYDEBUG instead of
936 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
937 and so that YYFPRINTF is guaranteed to be defined here.
939 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
941 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
943 (muscle_percent_define_check_values): ... this more helpful function.
944 Again, it's not used yet, but it will be.
945 * src/muscle_tab.h: Likewise.
947 Improve some comments in parser table construction.
948 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
949 (generate_states): Don't mention ruleset, which is internal to closure.
950 * src/closure.c (closure): Explain sorting of core and itemset, which
951 is required for this function to behave correctly.
952 * src/closure.h (closure): Mention sorting.
954 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
956 * src/lalr.c (state_lookahead_tokens_count): For code readability,
957 move the check for disabled transitions to an aver since conflict
958 resolution hasn't happened yet.
960 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
961 labels a state as inconsistent just because it has error transitions.
962 The original form of this check appeared in revision 1.1 of lalr.c,
963 which was committed on 1991-12-21. Now (at least), changing the
964 consistency label on such a state appears to have no useful effect in
965 any of the places it is examined, which I enumerate below. The key
966 point to understanding each item in this enumeration is that a state
967 with an error transition is labelled consistent in the first place only
968 if it has no rules, so the check cannot matter for states that have
969 rules. (1) Labelling a state as inconsistent will cause set_conflicts
970 to try to identify its conflicts, and a state must have *rules* to have
971 conflicts. (2) Labelling a state as inconsistent will affect how
972 action_row sets the default *rule* for the state. (3) Labelling a
973 state as inconsistent will cause build_relations to add lookback edges
974 to *rules* in that state.
975 * src/state.h (struct state): Word the comment for member consistent
978 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
980 Don't depend on C99 features.
981 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
982 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
983 * src/reader.c (check_and_convert_grammar): Fix for-loop.
984 * src/state.c (state_mark_reachable_states): Fix for-loop.
985 (state_remove_unreachable_states): Fix for-loop.
987 Don't widen struct state with member reachable just to temporarily
988 record reachability. Instead, use a local bitset.
989 * src/state.h (struct state): Remove member.
990 * src/state.c (state_new): Don't initialize it.
991 (state_mark_reachable_states): Rename to...
992 (state_record_reachable_states): ... this, and use bitset.
993 (state_remove_unreachable_states): Use bitset.
995 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
997 * src/Makefile.am (yacc): Quote target action commands properly so
998 that the yacc script isn't corrupt. Reported by Hans Aberg at
999 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
1001 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
1002 the case of pure parsers. Reported by Frans Englich at
1003 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
1004 * THANKS: Add Frans Englich.
1006 * NEWS (2.3a+): In the %code entry, reference section `Bison
1007 Declaration Summary' from the manual now since the %code summary has
1009 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
1010 in the rules section must be terminated by semicolons.
1012 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>

1039 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
1040 tests/existing.at: Update copyright date.
1042 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1044 If conflict resolution makes states unreachable, remove those states,
1045 report rules that are then unused, and don't report conflicts in those

1066 Minor code cleanup in parser table construction.
1067 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
1068 (new_itemsets, save_reductions): Update for rename to nitemset.
1069 * src/closure.c (nritemset): Rename to...
1070 (nitemset): ... this since the "r" appears to meaningless and isn't
1071 used in the comments.
1072 (closure): Update for rename.

1161 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
1162 Bison uses of names rather than just skeleton uses of names.
1163 (b4_percent_define_get, b4_percent_define_ifdef): Rename

1177 b4_percent_define_loc(VARIABLE) to report the location of an invalid
1179 (b4_percent_define_default): Save a special location in

1205 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
1207 * data/lalr1.java: Prefix all private members with yy.
1209 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
1211 Use YYFPRINTF instead of fprintf where appropriate. Reported by
1212 Sebastien Fricker at

1229 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
1231 Undo my 2007-02-07 change, switching back to the c-strcase module
1232 introduced in the 2007-02-03 change. Bruno Haible reported that
1233 the 2007-02-07 change would be dangerous in Turkish if we add a
1234 language whose name contains "i", since "i" is not lowercase "I"
1236 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
1237 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
1238 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
1239 * m4/.cvsignore: Remove strcase.m4.
1240 * src/getargs.c: Revert 2007-02-07 change, as follows.
1241 Include c-strcase.h.
1242 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
1244 2007-02-11 Bruno Haible <bruno@clisp.org>
1246 Enable the Java related testsuite tests when the only Java compiler
1247 found is a gcj < 4.3. Discussed at
1248 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
1249 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
1251 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
1253 * data/Makefile.am: Update copyright date.
1254 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
1255 yypstate_new returns NULL.
1256 (yypstate_new): Return NULL if malloc does.
1257 * src/reader.c (packgram): Move translation of rule actions from the
1258 beginning of packgram to...
1259 (check_and_convert_grammar): ... here right before packgram is invoked
1260 so it's easier to write more complete comments, and remove redundant
1263 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
1265 As in semantic actions, make @$ in %initial-action, %destructor, and
1266 %printer imply %locations.
1267 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
1269 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
1270 (@$ in %initial-action implies %locations,
1271 @$ in %destructor implies %locations,
1272 @$ in %printer implies %locations): ... these new test cases.
1274 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
1276 Undo most of the 2007-02-03 change, switching to the strcase module
1277 now that gnulib strcase has been fixed.
1278 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
1279 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
1280 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
1281 * m4/.cvsignore: Add strcase.m4.
1282 * src/getargs.c: Revert 2007-02-03 change, as follows.
1283 Don't include c-strcase.h.
1284 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
1285 strcasecmp has "unspecified behavior" outside the POSIX locale,
1286 but it works fine in practice if at least one argument is ASCII,
1287 as is the case in Bison.
1289 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
1291 * tests/java.at: Skip tests if only one of javac/java is present.
1292 Reported by Joel E. Denny.
1293 * tests/atlocal.in: Adjust copyright years.
1295 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
1297 * data/lalr1.java (Stack): Work around old verifiers that disallow
1298 access to the private fields of an inner class, from the outer class.
1299 We can make Stack's fields public because user code doesn't have access
1300 to the instance of Stack used by parse(). Reported by Paul Eggert.
1302 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1304 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
1305 the right spot for these files?
1306 * bootstrap.conf (gnulib_modules): Add c-strcase.
1307 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
1309 * src/getargs.c: Include c-strcase.h.
1310 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
1311 to avoid unspecified behavior.
1313 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
1315 * doc/bison.texinfo (Decl Summary): Correct typo.
1317 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
1319 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
1320 Complain if the value does not match empty, "true" or "false".
1321 * data/c++.m4: Adjust default definitions of %define variables.
1322 * data/java.m4: Adjust default definitions of %define variables.
1323 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
1325 * tests/input.at (Boolean %define variables): Test new behavior.
1327 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
1329 * NEWS: Mention java.
1330 * TODO: Remove things that are done.
1331 * bootstrap.conf: Add javacomp-script and javaexec-script.
1332 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.

1336 * data/java.m4: New.
1337 * data/lalr1.java: New.
1339 * doc/bison.texinfo: Put "A Complete C++ Example" under
1340 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
1341 under Other Languages.
1343 * src/getargs.c (valid_languages): Add Java.
1344 * src/getargs.h (struct bison_language): Update size of string fields.
1346 * tests/Makefile.am: Add java.at.
1347 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
1348 * tests/java.at: New.
1349 * tests/testsuite.at: Include it.
1351 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
1354 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
1355 at_directive_argv arguments so these no longer have to be global
1356 variables. Also, update the implementation for the following changes.
1357 (fail_for_at_directive_too_many_args,
1358 fail_for_at_directive_too_few_args): Add at_directive_name argument.
1359 (at_directive_name): Remove as at_directive_argv[0] will be used for
1361 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
1362 for the directive name.

1364 skel_lex instead of global.
1365 (INITIAL): Update directive start action for above changes.
1366 (SC_AT_DIRECTIVE_ARG): Rename to...
1367 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
1368 (SC_AT_DIRECTIVE_SKIP_WS): Update.
1369 (scan_skel): Move yylex_destroy to...
1370 (skel_scanner_free): ... here.
1371 * tests/skeletons.at (installed skeleton file name): Rename to...
1372 (installed skeleton file names): ... this.
1374 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
1376 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1377 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
1378 Summary" not "Directives".
1379 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
1380 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
1381 since the former is now the more complete one.
1382 (Prologue Alternatives): Likewise and do the same for %defines.
1383 (Table of Symbols): Add summary of %code, add summary of %define, and
1384 move full %code documentation to...
1385 (Decl Summary): ... here for consistency with other entries in these
1387 Move %define entry in order to keep this list alphabetized.
1388 Reword %define entry a little to put less emphasis on the skeleton
1389 concept, which most users shouldn't have to think about.
1391 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
1393 Adjust to recent gnulib changes.
1394 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
1395 Add string.h, string_.h, unistd_.h, wchar_.h.
1396 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
1397 * src/system.h: Don't include <stpcpy.h>; this is now done by
1400 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
1402 Simplify implementation of unqualified %code, implement macros for
1403 uniform treatment of boolean %define flags. Document %define.
1404 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
1405 b4_percent_code_ifdef): New.
1406 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
1407 * data/c++.m4: Define default value for global_tokens_and_yystype.
1408 * data/glr.cc: Likewise.
1409 * data/location.cc: Use b4_percent_define_flag_if.
1411 * doc/bison.texinfo (Decl Summary): Document %define.
1413 * src/parse-gram.y (Unqualified %code): Change muscle name to
1415 (content.opt): Default to empty.
1417 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1419 Implement support for relative and absolute skeleton file names.
1420 Discussed starting at
1421 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
1422 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
1423 (Bison Options): Document in --skeleton entry.
1424 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
1425 full_skeleton can't necessarily hold all of pkgdatadir.
1426 If the specified skeleton file name contains a `/', don't prepend
1428 * src/parse-gram.y (prologue_declaration): If the specified skeleton
1429 file name contains a `/', prepend the grammar file directory.
1430 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
1431 * skeletons.at: New file.
1432 (relative skeleton file names): New test case.
1433 (installed skeleton file names): New test case.
1434 * tests/testsuite.at: Include skeletons.at.
1436 * bootstrap: Update copyright to 2007.
1438 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
1440 * bootstrap: Remove occurrences of .#bootmp from the files.
1442 2007-01-17 Akim Demaille <akim@epita.fr>
1444 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
1446 Use per-type %printer.
1448 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1450 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

1458 2007-01-16 Akim Demaille <akim@epita.fr>
1460 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
1462 (Calc++ Scanner): Exit with failure if we can't open the input
1464 Accept "-" standing for stdin.
1465 (Calc++ Top Level): Print the result only if the parsing was
1468 2007-01-16 Akim Demaille <akim@epita.fr>
1470 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
1472 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
1473 and Joel E. Denny <jdenny@ces.clemson.edu>
1475 Clean up %define and %code implementation in M4 some. Most
1476 importantly, rename all related macros to be in the b4_percent_define
1477 and b4_percent_code namespaces. Also, complete support for `.' in
1478 %define variable names and %code qualifiers.
1479 * data/bison.m4 (b4_check_user_names): Check for special
1480 "SKELETON-NAMESPACE(name)" macros instead of using two nested
1482 (b4_get_percent_define, b4_get_percent_code): Rename to...
1483 (b4_percent_define_get, b4_percent_code_get): ... these.
1484 Extend documentation with examples.
1485 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
1486 b4_percent_define_skeleton_variables and
1487 b4_percent_code_skeleton_qualifiers.
1488 Expect any value for the %define variable `foo' to be stored in the
1489 macro named `b4_percent_define(foo)'; expect any %code blocks for the
1490 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
1491 expect any unqualified %code blocks to be stored in a macro named
1492 `b4_percent_code_unqualified'.
1493 Use m4_indir so that %define variable names and %code qualifiers can
1494 contain `.', which is allowed by the grammar parser.
1495 (b4_percent_define_default): New macro to set a default value for a
1497 (m4_wrap): Update wrapped code, and fix some underquoting.
1498 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
1499 Expect grammar uses of %define variables and %code qualifiers to be
1500 defined in b4_percent_define_user_variables and
1501 b4_percent_code_user_qualifiers.
1502 * data/c++.m4: Use b4_percent_define_default rather than
1503 m4_define_default. Fix some underquoting. Skeleton usage of %define
1504 variable define_location_comparison now implies skeleton usage of
1505 %define variable filename_type.
1506 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1507 data/push.c, data/yacc.c: Update macro names.
1508 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
1511 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
1513 DJGPP specific issues.
1515 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
1516 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
1518 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1520 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
1521 run parsers in all tests so that Valgrind is invoked during
1522 maintainer-check-valgrind.
1523 (Duplicate representation of merged trees): Free all semantic values.
1524 (Duplicated user destructor for lookahead): Likewise.
1526 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1528 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
1529 command-line prefix.
1530 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
1531 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
1532 miss Valgrind messages.
1533 (Exploding the Stack Size with Malloc): Likewise.
1535 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1537 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
1538 locals. Reported by Juan Manuel Guerrero at
1539 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
1540 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
1541 Fix some indentation also.
1542 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
1543 explaining this issue.
1545 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
1546 and Joel E. Denny <jdenny@ces.clemson.edu>
1548 Simplify union and prologue handling, and escape union and lex/parse
1549 params with digraphs.
1550 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
1551 values to the empty string since these are no longer guaranteed
1552 initialized by the front-end.
1553 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
1554 braces around b4_user_stype since this is no longer done by the
1556 * src/files.c, src/files.h (pre_prologue_obstack,
1557 post_prologue_obstack): Remove.
1558 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
1559 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
1560 with digraphs. This fixes lex params and parse params.
1561 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
1562 * src/output.c (prepare): Remove muscle insertion of the prologues.
1563 (output): Remove freeing of pre_prologue_obstack and
1564 post_prologue_obstack.
1565 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
1566 than prologue_augment for prologue parsing so you don't need prologue
1568 (grammar_declaration): For %union RHS, use `braceless' instead of
1569 "{...}" so that braces are already stripped and code is escaped with
1571 * src/reader.c (prologue_augment): Remove.
1572 (reader): Remove initialization of pre_prologue_obstack and
1573 post_prologue_obstack.
1574 * src/reader.h (prologue_augment): Remove.
1576 * data/c.m4: Remove stray parenthesis.
1578 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1580 Remove quotes from variables names in %define directives and from
1581 qualifiers in %code directives, and restrict the characters that are
1582 allowed in them to M4-friendly ones. For %define, continue to support
1583 the quoted form as a deprecated feature. Discussed starting at
1584 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
1585 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
1587 * doc/bison.texinfo (Prologue Alternatives): Update.
1588 (Decl Summary): In %defines entry, update mention of `%code requires'
1589 and `%code provides'.
1590 (C++ Location Values): Update %define uses.
1591 (Calc++ Parser Interface): Likewise.
1592 (Calc++ Parser): Likewise, and update `%code requires' uses.
1593 (Table of Symbols): Update %code documentation.
1594 * src/parse-gram.y (prologue_declaration): For %define variables, use
1595 `variable' instead of `STRING'.
1596 (grammar_declaration): For %code qualifiers, use `ID' instead of
1598 (variable): New nonterminal that takes an `ID' or a `STRING'.
1599 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
1601 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
1602 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
1603 (%define errors): Update %define uses.
1605 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1607 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
1608 instead of muscle_insert for %define values so that M4-special
1609 characters are replaced with digraphs.
1610 * tests/input.at (%define errors): Extend to check weird values.
1612 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1614 Instead of having skeletons declare all valid %define variables and
1615 %code qualifiers, provide macros that retrieve the associated values
1616 and build these lists automatically. Thus Bison will now warn when a
1617 variable or qualifier is not used by the skeleton in the current
1618 invocation regardless of whether it might sometimes be used by that
1619 skeleton in other invocations. Also, move all %define value macros to
1620 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
1621 form, which is replaced by %code.
1622 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
1623 (b4_check_user_names): ... this, and change the series of valid name
1624 arguments to a single list argument for names used in the skeleton
1625 similar to the existing list argument for names used in the grammar.
1626 Warn instead of complaining.
1627 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
1628 values and %code code, to format %code code properly, and to build
1629 lists of all %define variables and %code qualifiers used in the
1630 skeleton: b4_skeleton_percent_define_variables and
1631 b4_skeleton_percent_code_qualifiers.
1632 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
1634 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
1635 the skeleton names lists can finish building first. In place of
1636 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
1637 expect the lists b4_user_percent_define_variables and
1638 b4_user_percent_code_qualifiers.
1639 * data/c++.m4: Where setting default values for b4_parser_class_name,
1640 b4_location_type, b4_filename_type, b4_namespace, and
1641 b4_define_location_comparison, update their names to the
1642 b4_percent_define_ namespace.
1643 * data/glr.c: Don't use b4_check_percent_define_variables and
1644 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
1645 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
1646 (b4_parser_class_name, b4_namespace): Define these using
1647 b4_get_percent_define for parser_class_name and namespace.
1648 * data/location.cc: Use b4_get_percent_define.
1649 * data/push.c: Don't use b4_check_percent_define_variables and
1650 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
1651 * data/yacc.c: Likewise, and don't call m4_exit in
1652 b4_use_push_for_pull_if or m4_wrap code will never execute.
1653 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
1655 (muscle_grow_user_name_list): ... this for consistency with the
1656 terminology used in bison.m4.
1657 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
1658 %define variable names, and rename muscle used_percent_define_variables
1659 to user_percent_define_variables.
1660 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
1661 user_percent_code_qualifiers.
1663 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
1664 {CODE} form is no longer accepted.
1665 * tests/input.at (Reject bad %code qualifiers): Rename to...
1666 (Reject unused %code qualifiers): ... this, and update test output.
1667 (%define error): Update test output.
1669 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
1671 Check for unrecognized %define variables similar to checking for
1672 unrecognized %code qualifiers. Check for redefined %define variables.
1673 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
1675 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
1676 (b4_check_percent_define_variables): New, also wraps it.
1677 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
1678 variables using b4_check_percent_define_variables.
1679 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
1680 all those exercised in the test suite and all those listed in the
1681 `Default values' section of c++.m4. Are there others?
1682 * data/push.c, data/yacc.c: Declare no valid %define variables.
1683 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
1684 similar to muscle_find, but it works even when the muscle stores a
1686 (muscle_grow_used_name_list): New function for constructing the used
1687 name list muscles that b4_check_for_unrecognized_names requires.
1688 * src/parse-gram.y (prologue_declaration): Warn if a variable is
1689 %define'd more than once. Define the b4_used_percent_define_variables
1690 muscle with muscle_grow_used_name_list.
1691 (grammar_declaration): Abbreviate %code code with
1692 muscle_grow_used_name_list.
1693 * tests/input.at (%define errors): New.
1695 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
1697 Provide warn_at, complain_at, and fatal_at function callbacks to the
1698 skeletons, and use this for %code qualifier complaints.
1699 * data/bison.m4 (b4_error_at): New, invoked by...
1700 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
1701 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
1702 @fatal_at(...@) directives.
1703 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
1704 qualifiers in b4_used_percent_code_qualifiers and to use
1706 * src/location.c, src/location.h (boundary_set_from_string): New global
1708 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
1710 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
1711 to b4_used_percent_code_qualifiers.
1712 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
1714 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
1715 (lineno): Rename to...
1716 (out_lineno): ... this so I don't misunderstand it again.
1717 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
1718 here; these newlines are in the input but not the output file.
1719 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
1720 (at_directive_perform): ... this new static function, and add handling
1721 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
1723 * tests/input.at (Reject bad %code qualifiers): Update test output with
1724 locations and extend.
1726 * tests/output.at (Output file name: [, Output file name: ]): Remove
1727 bogus comment about these tests failing.
1729 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
1731 Clean up b4_check_percent_code_qualifiers a little.
1732 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
1733 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
1734 documentation and add examples.
1735 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
1738 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
1740 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
1741 unreliable -- especially when they're hidden inside another macro.
1742 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
1743 data/c.m4: Remove m4_divert(-1).
1744 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1745 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
1746 m4_divert_push(0) and m4_divert_pop(0).
1747 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
1748 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
1749 pushed and popped by m4sugar, should be first on the stack.
1751 Provide warn, complain, and fatal function callbacks to the skeletons.
1752 This provides more flexibility than m4_fatal, improves the error
1753 message format, and captures messages for translation. Discussed
1755 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
1756 * data/bison.m4 (b4_error): New, invoked by...
1757 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
1758 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
1759 directives. Because these M4 macros might be called when the current
1760 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
1761 the previous removal of uses of m4_divert, which caused trouble.
1762 (b4_check_percent_code_qualifiers): Use b4_complain instead of
1763 m4_fatal to report unrecognized %code qualifiers.
1764 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
1765 push parser requests.
1766 * data/glr.c: Use b4_complain instead of m4_fatal to report
1767 non-deterministic push parser requests.
1768 Update @output usage to @output(...@) form.
1769 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
1770 report missing %defines. Update @output usage to @output(...@) form.
1771 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
1773 * src/main.c (main): Invoke skel_scanner_free.
1774 * src/scan-skel.h (skel_scanner_free): Prototype new function.
1775 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
1776 obstack_for_string from flex-scanner.h.
1777 (YY_DECL): Use to declare skel_lex static.
1778 (decode_at_digraphs): Remove; now handled in the new
1779 SC_AT_DIRECTIVE_ARG start condition.
1780 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
1782 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
1783 at_directive_argv): New static globals.
1784 (INITIAL): Use fail_for_invalid_at.
1785 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
1786 recognize the start of a generalized `@directive(...@)' form and
1788 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
1789 directive args (using the new obstack_for_string), to decode the
1790 contained @ diagraphs, and to perform the directive. It recognizes
1791 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
1793 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
1794 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
1796 (scan_skel): Initialize obstack_for_string on the first call.
1797 (skel_scanner_free): New function to free obstack_for_string.
1798 * tests/input.at (Reject bad %code qualifiers): Update test output.
1800 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
1802 Consolidate the 4 prologue alternative directives (%code, %requires,
1803 %provides, and %code-top) into a single %code directive with an
1804 optional qualifier field. Discussed at
1805 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
1806 * NEWS (2.3a+): Rewrite the existing entry for the prologue
1808 * doc/bison.texinfo (Prologue Alternatives): Update.
1809 (Decl Summary): Update to %code "requires" and %code "provides".
1810 (Calc++ Parser): Update to %code "requires".
1811 (Table of Symbols): Remove entries for %requires, %provides, and
1812 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
1813 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
1814 are replaced by b4_percent_code_provides and b4_percent_code_requires,
1815 which are skeleton-specific.
1816 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
1817 declare what %code qualifiers it supports and to complain if any other
1818 qualifiers were used in the grammar.
1819 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
1820 and b4_user_code([b4_percent_code_provides]) in place of
1821 b4_user_requires and b4_user_provides.
1822 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
1823 Add b4_user_code([b4_percent_code_top]) and
1824 b4_user_code([b4_percent_code]).
1825 Invoke b4_check_percent_code_qualifiers.
1826 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
1827 PERCENT_REQUIRES): Remove.
1828 (grammar_declaration): Remove RHS's for %code-top, %provides, and
1829 %requires. Rewrite the %code RHS as the unqualified form defining the
1830 muscle b4_percent_code. Add another RHS for the qualified %code form,
1831 which defines muscles of the form b4_percent_code_QUALIFIER and the
1832 b4_used_percent_code_qualifiers muscle.
1833 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
1834 PERCENT_REQUIRES): Remove.
1835 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
1836 %code "requires" and %code "provides".
1837 * tests/input.at (Reject bad %code qualifiers): New.
1839 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
1841 Use the new code_props interface for destructors and printers.
1842 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
1843 printer_location members, and change the type of the destructor and
1844 printer members to code_props.
1845 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
1846 symbol_printer_get, semantic_type_destructor_set,
1847 semantic_type_printer_set, default_tagged_destructor_set,
1848 default_tagless_destructor_set, default_tagged_printer_set,
1849 default_tagless_printer_set): Use code_props in arguments and return
1850 types in place of char const * and location.
1851 (symbol_destructor_location_get, symbol_printer_location_get): Remove
1852 since the locations are now contained in the return of
1853 symbol_destructor_get and symbol_printer_get.
1854 * src/output.c (symbol_destructors_output, symbol_printers_output):
1856 (symbol_code_props_output): ... this to eliminate duplicate code.
1857 (output_skeleton): Update to use symbol_code_props_output.
1858 * src/reader.c (symbol_should_be_used): Update use of
1859 symbol_destructor_get.
1860 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
1861 Update uses of the various _destructor_set and _printer_set functions.
1862 * src/symtab.c: (default_tagged_destructor_location,
1863 default_tagless_destructor_location, default_tagged_printer_location,
1864 default_tagless_printer_location): Remove since we...
1865 (default_tagged_destructor, default_tagless_destructor,
1866 default_tagged_printer, default_tagless_printer): ... change the type
1867 of these to code_props.
1868 (symbol_new, semantic_type_new, symbol_destructor_set,
1869 semantic_type_destructor_set, symbol_destructor_get,
1870 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
1871 symbol_check_alias_consistency, default_tagged_destructor_set,
1872 default_tagless_destructor_set, default_tagged_printer_set,
1873 default_tagless_printer_set): Update.
1874 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
1875 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
1877 (symbol_print): Use SYMBOL_CODE_PRINT.
1879 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
1881 Use the new code_props interface for rule actions.
1882 * src/symlist.h (symbol_list): Replace action, action_location, and
1883 used members with a code_props action_props member.
1884 * src/reader.c (symbol_should_be_used, grammar_rule_check,
1885 grammar_midrule_action, grammar_current_rule_merge_set,
1886 grammar_current_rule_symbol_append, packgram): Update.
1887 * src/scan-code.h (translate_rule_action): Remove, no longer used.
1888 * src/scan-code.l (handle_action_dollar): Update.
1889 (translate_rule_action): Remove, no longer used.
1890 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
1892 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
1894 Use the new code_props interface in parse-gram.y.
1895 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
1896 Update all uses of translate_* functions to use the new code_props
1897 interface and to use gram_scanner_last_string_free and
1898 code_scanner_last_string_free where possible.
1899 (grammar_declaration): symbol_list_destructor_set and
1900 symbol_list_printer_set now perform the translation, so don't do it
1901 here. Use gram_scanner_last_string_free where possible.
1902 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
1903 translate_code): Remove, no longer used.
1904 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
1905 symbol_list_printer_set): Perform code translation here rather than
1906 depending on the caller to do so.
1908 * src/symlist.h (struct symbol_list): Correct some documentation typos.
1909 * src/scan-gram.h (gram_last_string): Remove declaration.
1910 * src/scan-gram.l (last_string): Declare it static.
1912 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
1914 Encapsulate code properties and related functionality for the various
1915 destructors, printers, and actions into a code_props structure and
1916 interface. This patch merely implements code_props in scan-code.h and
1917 scan-code.l. Future patches will rewrite other modules to use it.
1918 Discussed starting at
1919 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
1920 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
1921 consistently initialize const structs that have an empty location
1923 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
1924 to ensure consistency.
1925 * src/scan-code.h (code_props): New structure.
1926 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
1927 function, macro, and const global variable for initializing a
1928 code_props with no code.
1929 (code_props_plain_init, code_props_symbol_action_init,
1930 code_props_rule_action_init, code_props_translate_code): The rest of
1931 the new code_props functional interface. Among other things, the init
1932 functions set the code_props kind field so that
1933 code_props_translate_code will know whether to behave like
1934 translate_symbol_action, translate_rule_action, or translate_code.
1935 These old translate functions must remain until all other modules are
1936 updated to use the new code_props interface.
1937 (code_scanner_last_string_free): New function similar to
1938 gram_scanner_last_string_free.
1939 (code_scanner_free): Add documentation.
1940 * src/scan-code.l: Implement the new interface.
1941 (code_lex): Make it static, add a code_props* argument, and remove the
1943 (last_string): New static global similar to the one in scan-gram.l.
1944 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
1946 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
1947 code_props since Bison may one day use this information for destructors
1949 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
1950 (handle_action_dollar): Use symbol_list_n_get and set used flag
1951 directly since symbol_list_n_used_set is removed.
1952 (translate_action): Add a code_props* argument and remove the rule,
1953 action, and location arguments. Pass the code_props* on to code_lex.
1954 (translate_rule_action, translate_symbol_action, translate_code):
1955 Rewrite as wrappers around the new code_props interface.
1956 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
1957 it would eventually need to break the encapsulation of code_props.
1959 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
1961 * etc/.cvsignore: New.
1963 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
1965 Add maintainer-push-check to run maintainer-check using push parsing in
1966 place of pull parsing where available.
1967 * Makefile.am (maintainer-push-check): New.
1968 * data/bison.m4 (b4_use_push_for_pull_if): New.
1969 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
1970 appropriately based on their existing values.
1971 (yypush_parse): Don't print push-parser-specific diagnostics if push
1972 parsing is being used in place of pull parsing.
1973 * data/yacc.c: If push parsing should replace pull parsing, redirect to
1975 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
1976 variable, and insert b4_use_push_for_pull_flag into muscles.
1977 * tests/Makefile.am (maintainer-push-check): New.
1979 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
1981 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
1982 (whether successful or failed) so that yypush_parse can be invoked
1983 again to start a new parse using the same yypstate.
1984 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
1985 check multiple yypull_parse invocations on the same yypstate. For pull
1986 mode, extend to check multiple yyparse invocations.
1987 (Exploding the Stack Size with Alloca): Extend to try with
1989 (Exploding the Stack Size with Malloc): Likewise.
1991 * tests/calc.at (Simple LALR Calculator): Don't specify
1992 %skeleton "push.c" since %push-pull-parser implies that now.
1993 * tests/headers.at (export YYLTYPE): Don't check for the push
1994 declarations. Otherwise, this test case can't be used to see if push
1995 mode can truly emulate pull mode.
1996 * tests/input.at (Torturing the Scanner): Likewise.
1997 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
1998 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
1999 AT_YACC_IF, which now includes the case of push mode since %skeleton
2000 need not be used for push mode. This will be more intuitive once
2001 push.c is renamed to yacc.c.
2003 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2005 For push mode, convert yyparse from a macro to a function, invoke yylex
2006 instead of passing a yylexp argument to yypull_parse, and don't
2007 generate yypull_parse or yyparse unless %push-pull-parser is declared.
2008 Discussed starting at
2009 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
2010 * data/bison.m4 (b4_pull_if): New.
2011 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
2012 * data/push.c: Improve M4 quoting a little.
2013 (b4_generate_macro_args, b4_parenthesize): Remove.
2014 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
2015 any time a pull parser is requested.
2016 Don't #define this as a wrapper around yypull_parse. Instead, when
2017 both push and pull are requested, make it a function that does that
2019 (yypull_parse): If there's a b4_prefix, #define this to
2020 b4_prefix[pull_parse] when both push and pull are requested.
2021 Don't define this as a function unless both push and pull are
2023 Remove the yylexp argument and hard-code yylex invocation instead.
2024 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
2026 * src/getargs.c (pull_parser): New global initialized to true.
2027 * getargs.h (pull_parser): extern it.
2028 * src/output.c (prepare): Insert pull_flag muscle.
2029 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
2030 (prologue_declaration): Set both push_parser and pull_parser = true for
2031 %push-pull-parser. Set push_parser = true and pull_parser = false for
2033 * src/scan-gram.l: Don't accept %push_parser as an alternative to
2034 %push-parser since there's no backward-compatibility concern here.
2035 Scan %push-pull-parser.
2036 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
2037 instead of %push-parser.
2038 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
2039 prototype it in the module that calls yyparse.
2040 * tests/input.at (Torturing the Scanner): Likewise.
2041 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
2043 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
2045 Update etc/bench.pl. Optimize push mode a little (the yyn change
2046 deserves most of the credit).
2047 * Makefile.am (SUBDIRS): Add etc subdirectory.
2048 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
2049 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
2050 yytoken, yyval, and yyloc declarations to...
2051 (yyparse or yypush_parse): ... here to improve performance. For
2052 yypush_parse invocations after the first, be sure to assign yyn its old
2054 (yypstate_new): Don't bother initializing the yyresult field since the
2055 initial value isn't used.
2056 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
2057 remove the #define that, in push mode, set it to yyps->NAME.
2058 * etc/Makefile.am: New.
2059 * etc/bench.pl: Remove and build it instead from...
2060 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
2061 "tests/bison" from the build directory by default rather than just
2062 invoking "bison" from $PATH.
2063 (calc_grammar): Update push parser code: don't declare yylval globally,
2064 don't define yyparse_wrapper, and don't #define yyparse.
2065 (bench_grammar): Update to check all working combinations of yacc.c,
2066 push.c, impure, pure, pull, and push.
2068 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2070 For push mode, add pull wrappers around yypush_parse.
2071 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
2072 (yypull_parse): New function wrapping yypush_parse.
2073 (yyparse): New #define wrapping yypull_parse.
2074 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
2076 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
2077 prototype yylex in the module that calls yyparse, and don't prototype
2078 yyparse there. Otherwise, the yyparse expansion won't compile.
2079 * tests/input.at (Torturing the Scanner): Likewise.
2081 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2083 Enable push parsers to operate in impure mode. Thus, %push-parser no
2084 longer implies %pure-parser. The point of this change is to move
2085 towards being able to test the push parser code by running the entire
2086 test suite as if %push-parser had been declared.
2087 * data/push.c (yypush_parse): For impure mode, remove the
2088 yypushed_char, yypushed_val, and yypushed_loc arguments.
2089 Instead, declare these as local variables initialized to the global
2090 yychar, yylval, and yylloc.
2091 For the first yypush_parse invocation only, restore the initial values
2092 of these global variables when it's time to read a token since they
2093 have been overwritten.
2094 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
2096 * tests/calc.at (Simple LALR(1) Calculator): Always declare
2097 %pure-parser along with %push-parser since this test case was designed
2098 for pure push parsers.
2099 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
2100 (AT_YACC_OR_PUSH_IF): New.
2101 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
2102 add a note that it's still wrong for some cases (as it has been for a
2104 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
2105 %push-parser no longer implies %pure-parser.
2107 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2109 Remove some unnecessary differences between the pull parser code and
2110 the push parser code. This patch enables yynerrs in push mode.
2111 * data/push.c: Reformat M4 a little.
2112 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
2113 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
2114 because push mode is on. Instead, if pure mode is on, move yynerrs
2116 (b4_declare_parser_state_variables): ... here.
2117 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
2118 to yyps->NAME so it can be used in yypush_parse.
2119 (yypush_parse): Don't omit uses of yynerrs in push mode.
2121 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2123 Fix bug such that the first pushed token's value and location are
2124 sometimes overwritten (sometimes by %initial-action) before being used.
2125 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
2126 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
2127 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
2128 more closely mimic the pull parser logic.
2129 Don't copy the pushed token to yychar, yylval, and yylloc until it's
2130 time to read a token, which is after any initialization of yylval and
2132 (gottoken): Rename label to...
2133 (yyread_pushed_token): ... for clarity and to avoid infringing on the
2136 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2138 Rearrange initialization of the parser state variables so that the
2139 skeleton doesn't have to have a copy for pull mode and another for push
2140 mode. This patch also fixes at least a bug such that yylloc was not
2141 initialized (with b4_location_initial_line and
2142 b4_location_initial_column) upon calling yypush_parse. However, that
2143 initialization now overwrites the first token's location;
2144 %initial-action assigning @$ already did the same thing, and both bugs
2145 will be fixed in a later patch.
2146 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
2147 (b4_declare_parser_state_variables): Remove initialization of yytoken,
2148 yyss, yyvs, yyls, and yystacksize.
2149 (yypstate_new): Remove initialization of some yypstate fields: yystate,
2150 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
2152 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
2153 yyps->NAME so it can be used in yypush_parse.
2154 (yyparse or yypush_parse): For yypush_parse, don't print the
2155 "Starting parse" diagnostic for invocations after the first.
2156 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
2157 yypush_parse, only do it for the first invocation.
2158 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
2159 initialization to occur in yypush_parse but only on the first
2162 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2164 * data/push.c: Add CPP guards around push parser declarations in both
2165 the header and the code file.
2166 In the code file, move the push parser declarations to the same place
2167 they appear in the header file.
2168 Clean up the M4 some, especially the inconsistent underquoting in
2169 some b4_c_function_def and b4_c_function_decl uses.
2171 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2173 Encapsulate the push parser state variables into an M4 macro so the
2174 push skeleton doesn't have to list them again for pull mode's yyparse.
2175 For push mode, remove yypush_parse's local equivalents of these
2176 variables to eliminate unnecessary copying between the two sets at
2177 run-time. This patch also fixes at least a bug related to multiple
2178 %initial-action invocations in push mode.
2179 * data/push.c (b4_declare_parser_variables): Rename to...
2180 (b4_declare_scanner_communication_variables): ... this for clarity and
2182 (b4_declare_yyparse_variables): Remove and move its contents to the one
2183 spot where it was invoked.
2184 (b4_declare_parser_state_variables): New macro containing the parser
2185 state variables required by push mode.
2186 (struct yypstate): Replace all fields but yynew with
2187 b4_declare_parser_state_variables.
2188 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
2189 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
2190 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
2191 (yyparse or yypush_parse): For yyparse in pull mode, replace local
2192 parser state variable declarations with
2193 b4_declare_parser_state_variables.
2194 Don't initialize parser state variables when calling yypush_parse since
2195 yypstate_new already does that.
2196 Invoke the user's initial action only upon the first yypush_parse
2198 Remove all code that copies between the local parser state variables
2201 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2203 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
2204 prevent a name collision in a future patch where these names will
2205 sometimes be #define'd.
2206 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
2207 since it no longer has the same name as the existing argument.
2208 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
2210 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
2211 and Joel E. Denny <jdenny@ces.clemson.edu>
2213 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
2214 that the argument is case-insensitive, and there's no `=' here.
2215 For the %skeleton entry, mention that %language is better.
2216 (Bison Options): Likewise for --language and --skeleton. Move the
2217 --skeleton entry so that the `Tuning the parser' section is sorted
2218 alphabetically on long options.
2219 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
2220 %language directive in detail here; cross-reference the %language
2221 documentation instead.
2222 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
2223 `%require "2.3b"' so that the example is always up-to-date.
2224 (Table of Symbols): Add entries for %language and %skeleton.
2225 * examples/extexi (normalize): Instead of replacing every %require
2226 argument with the current Bison version, just substitute for
2227 `@value{VERSION}'. This guarantees that we're testing what actually
2228 appears in the documentation.
2229 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
2230 rather than `@VERSION@'.
2232 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2234 * NEWS: Reword the %language news a bit, and put it earlier.
2236 * src/getargs.c (skeleton_arg): Last arg is now location const *.
2237 Rewrite to simplify the logic.
2238 (language_argmatch): Likewise.
2239 (program_name): We now own this var.
2240 * src/getargs.h (struct bison_language): Use char[] rather than
2243 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
2245 * src/complain.c (program_name): Remove decl; no longer needed.
2246 * src/main.c (program_name): Remove; now belongs to getargs.
2248 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
2250 * NEWS: Document %language.
2252 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
2254 * data/c-skel.m4, data/c++-skel.m4: New files.
2255 * data/glr.c: Complain on push parsers.
2257 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
2259 (Decl Summary): Document %language and %skeleton.
2260 (Command line): Document -L.
2262 * examples/extexi: Rewrite %require directive.
2263 * examples/calc++/Makefile.am: Pass VERSION to extexi.
2265 * src/files.c (compute_exts_from_gc): Look in language structure
2267 (compute_file_name_parts): Check whether .tab should be added.
2268 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
2269 (language, skeleton_arg, language_argmatch): New.
2270 (long_options): Add --language.
2271 (getargs): Use skeleton_arg, add -L/--language.
2272 * src/getargs.h: Include location.h.
2273 (struct bison_language, language, skeleton_arg, language_argmatch): New.
2274 * src/output.c (prepare): Pick default skeleton from struct language.
2275 Don't dispatch C skeletons here.
2276 * src/parse-gram.y (PERCENT_LANGUAGE): New.
2277 (prologue_declaration): Add "%language" rule, use skeleton_arg.
2278 * src/scan-gram.l ("%language"): New rule.
2280 * tests/calc.at: Test %skeleton and %language.
2281 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
2282 (AT_GLR_IF): Look for %skeleton "glr.cc".
2283 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
2284 (AT_YACC_IF): Reject %language.
2286 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2288 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
2289 since it wasn't used; only the typedef name 'semantic_type' is needed.
2290 Also, omit trailing white space.
2292 * bootstrap: Sync from coreutils.
2293 (gnulib_extra_files): Add build-aux/announce.gen.
2294 (slurp): Adjust .gitignore files like .cvsignore files.
2295 * build-aux/announce-gen: Remove from CVS, since bootstrap
2298 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
2300 Make %push-parser imply %pure-parser. This fixes several bugs; see
2301 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
2302 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
2304 * data/push.c: Don't bother testing b4_push_if when deciding whether
2305 to expand b4_declare_parser_variables globally.
2306 (yypush_parse): Likewise in here.
2308 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
2309 (yy_reduce_print): Reformat M4 for readability.
2311 2006-12-15 Bob Rossi <bob@brasko.net>
2312 and Joel Denny <jdenny@ces.clemson.edu>
2314 * data/push.c (yypstate): Add typedef, and update all uses of
2315 struct yypstate to just yypstate.
2316 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
2318 2006-12-14 Bob Rossi <bob@brasko.net>
2320 * data/push.c (yypush_parse): Declare prototype regardless of
2323 2006-12-14 Bob Rossi <bob@brasko.net>
2325 * data/push.c (yyparse): Remove the prototype and the #define when in
2328 2006-12-13 Bob Rossi <bob@brasko.net>
2330 * data/push.c (yypstate_init): Rename to...
2331 (yypstate_new): ... this and use b4_c_function_def.
2332 (yypstate_delete): New.
2333 (yypush_parse): Change parameters yynval and yynlloc to be const.
2334 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
2335 yypstate_delete functions.
2337 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
2339 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
2340 strange test case titles. Reported by Bob Rossi.
2342 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
2344 * TODO: Add pointer to Sylvain Schmitz's work on static detection
2345 of potential ambiguities in GLR grammers.
2347 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
2349 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
2350 `bison ', use m4_index instead of m4_substr since chopping up a string
2351 containing M4-special characters causes problems here.
2353 Fix a couple of bugs related to special characters in user-specified
2354 file names, and make it easier for skeletons to compute output file
2355 names with the same file name prefix as Bison-computed output file
2357 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
2358 b4_parser_file_name and b4_spec_defines_file instead of
2359 @output_parser_name@ and @output_header_name@, which are now redundant.
2360 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
2361 b4_parser_file_name, b4_spec_defines_file, and the new
2362 @basename(FILENAME@) instead of @output_parser_name@ and
2363 @output_header_name@, which inappropriately escaped the file names as
2365 * src/files.c (all_but_ext): Remove static qualifier.
2366 (compute_output_file_names): Move `free (all_but_ext)' to...
2367 (output_file_names_free): ... here since all_but_ext is needed later.
2368 * src/files.h (all_but_ext): Extern.
2369 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
2370 exactly what MUSCLE_INSERT_STRING used to do.
2371 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
2372 characters are escaped properly.
2373 * src/output.c (prepare): Define muscle file_name_all_but_ext as
2375 For pkgdatadir muscle, maintain previous functionality by using
2376 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
2377 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
2378 digraphs would never be expanded. Hopefully no one has M4-special
2379 characters in his Bison installation path.
2380 * src/scan-skel.l: Don't parse @output_header_name@ and
2381 @output_parser_name@ anymore since they're now redundant.
2382 In @output, use decode_at_digraphs.
2383 Parse a new @basename command that invokes last_component.
2384 (decode_at_digraphs): New.
2385 (BASE_QPUTS): Remove unused.
2386 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
2387 (Output file name): New tests.
2389 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
2391 Warn about output files that are generated by the skeletons and that
2392 conflict with other output files.
2393 * data/glr.c: Don't generate the header file here when glr.cc does.
2394 * src/files.c (file_names, file_names_count): New static globals.
2395 (compute_output_file_names): Invoke output_file_name_check for files
2396 not generated by the skeletons and remove existing checks.
2397 (output_file_name_check): New function that warns about conflicting
2399 (output_file_names_free): Free file_names.
2400 * src/files.h (output_file_name_check): Declare.
2401 * src/scan-skel.l: Invoke output_file_name_check for files generated by
2403 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
2404 (Conflicting output files): New tests.
2406 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2408 * doc/bison.texinfo: Fix a couple of typos.
2410 2006-12-08 Bob Rossi <bob@brasko.net>
2412 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
2414 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
2416 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
2417 (yypush_parse): Rename yypvars argument to yyps and remove redundant
2419 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
2420 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
2422 2006-12-07 Bob Rossi <bob@brasko.net>
2423 and Joel Denny <jdenny@ces.clemson.edu>
2425 * data/push.c (yypvarsinit): Change return type from void* to struct
2426 yypvars*. No longer cast to void* on return.
2427 (struct yypvars): Remove yylen since it need not be remembered between
2428 yypushparse invocations.
2429 (yypushparse): Don't copy between yylen and pv->yylen.
2431 2006-12-05 Bob Rossi <bob@brasko.net>
2433 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
2434 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
2435 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
2436 (struct yypvars): Remove b4_declare_parser_variables.
2437 (yypvarsinit): Remove init code for removed variables.
2438 (global scope): Do not declare b4_declare_parser_variables if
2440 (yypushparse): Add b4_declare_parser_variables.
2441 Init new local variables, and remove init code for removed
2444 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
2445 and yyparse for other modes.
2446 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
2447 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
2448 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
2449 (AT_PURE_LEX_IF): True if pure or push parser.
2451 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
2453 Document Yacc prologue alternatives and default %destructor's and
2454 %printer's as experimental. Don't mention Java yet. Discussed at
2455 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
2456 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
2457 (2.3a): Annotate this entry to say the old forms of these features were
2459 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,

2463 2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
2465 Support a file name argument to %defines. Deprecate `=' in
2466 %file-prefix, %name-prefix, and %output. Discussed at
2467 <http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
2468 * NEWS (2.3a+): Mention.
2469 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
2470 form of %defines, and remove `=' from entries for %file-prefix,
2471 %name-prefix, and %output.
2472 * src/parse-gram.y (prologue_declaration): Implement.
2473 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
2474 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
2475 all but one occurrence of %name-prefix.
2476 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
2477 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
2478 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
2479 occurrence of each of %file-prefix and %output. Add check for %defines
2481 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
2482 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
2483 Remove the `=' from %output.
2485 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
2487 Don't escape $ in test case titles since Autoconf 2.61 now does that
2489 * tests/actions.at (Default %printer and %destructor are not for error
2490 or $undefined): Here.
2491 (Default %printer and %destructor are not for $accept): Here.
2492 * tests/input.at (Invalid $n and @n): Here.
2494 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
2496 Rename <!> to <>. Discussed starting at
2497 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
2498 * NEWS (2.3a+): Update.

2506 * tests/actions.at (Default tagless %printer and %destructor,
2507 Default tagged and per-type %printer and %destructor,
2508 Default %printer and %destructor are not for error or $undefined,
2509 Default %printer and %destructor are not for $accept,
2510 Default %printer and %destructor for mid-rule values): Update.
2511 * tests/input.at (Default %printer and %destructor redeclared,
2512 Unused values with default %destructor): Update.
2514 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
2516 Don't let %prec take a nonterminal.
2517 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
2519 * tests/input.at (%prec takes a token): New test checking that %prec
2520 won't take a nonterminal.
2522 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
2524 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
2525 it was double-quoted.
2526 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
2527 grammar is maintained with Bison's highest standards.
2528 * src/getargs.c: Fix some typos in Doxygen comments.
2530 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
2532 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
2533 later. Reported by Paul Eggert in
2534 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
2535 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
2536 * src/scan-code.l (translate_action): Don't bother invoking
2537 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
2538 (code_scanner_free): Instead of invoking
2539 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

2547 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
2548 has been called previously for the same key.
2549 (muscle_find): Return storage instead of value so that
2550 --enable-gcc-warnings doesn't produce warnings that the return discards
2551 const. aver that the value and storage are the same since storage
2552 could potentially be NULL when value is not.
2553 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
2556 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2558 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
2559 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
2560 us a slightly cleaner distribution, and also works.
2561 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
2564 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
2565 and Paul Eggert <eggert@cs.ucla.edu>
2567 Don't let Bison leak memory except when it complains.
2568 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
2569 (spec_defines_file, dir_prefix): Now char *, not const char *,
2570 since they are freed.
2571 * src/files.c: Likewise.
2572 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
2574 (tr): Now operates in-place. All uses changed.
2575 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
2577 (compute_file_name_parts, compute_output_file_names): Don't store
2578 read-only data in variables that will be freed.
2579 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
2580 src_extension, and header_extension.
2581 (output_file_names_free): New public function to free
2582 spec_verbose_file, spec_graph_file, spec_defines_file,
2583 parser_file_name, and dir_prefix.
2584 * src/getargs.c (getargs): Don't store read-only data in variables that
2586 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
2587 (which previously existed but was unused), and quotearg_free.
2588 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
2589 * src/muscle_tab.c: Likewise.
2590 (muscle_entry): Make the value char const *,
2591 and add a new storage member that is char * and can be freed.
2592 (muscle_entry_free): New private function.
2593 (muscle_init): Use it instead of free.
2594 (muscle_insert, muscle_grow): Update and use new storage member.
2595 (muscle_code_grow): Free the string passed to muscle_grow
2596 since it's not needed anymore.
2597 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
2598 add a new `char *code' member.
2599 ("{...}"): Declare semantic type as code.
2600 * src/scan-code.h (translate_rule_action):
2601 (translate_symbol_action, translate_code, translate_action): Return
2602 `char const *' rather than `char *' since external code should not free
2604 * src/scan-code.l: Likewise.
2605 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
2606 which is "{...}" in the parser.
2607 * tests/Makefile.am (maintainer-check-valgrind): Set
2608 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
2610 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
2612 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
2613 expecting a non-zero exit status sets --leak-check=summary and
2614 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
2615 this case, and we don't want to hear about it.
2617 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2619 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
2620 instead of from the template, to simplify configuration a bit.

2626 Disable unset/unused mid-rule value warnings by default, and recognize
2627 --warnings=midrule-values to enable them. Discussed starting at
2628 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
2629 * NEWS (2.3a+): Mention.

2631 warnings): Add entry for midrule-values subargument.
2632 * src/reader.c (symbol_should_be_used): Don't return true just because
2633 the value is a set/used mid-rule value unless
2634 --warnings=midrule-values was specified.
2635 * tests/input.at (Unused values, Unused values before symbol
2636 declarations): Run tests with and without --warnings=midrule-values.
2638 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
2639 than LIST_FREE directly.
2641 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
2643 Finish implementing --warnings=error, which should not be implied by
2644 --warnings=all (or by its synonyms -W and --warnings without
2646 * src/complain.c (set_warning_issued): New function to report that

2660 empty subargument list. For example: `bison --warnings= parser.y'.
2662 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
2664 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
2665 the parser header file so that gcc doesn't warn.
2667 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
2669 Split the default %destructor/%printer into two kinds: <*> and <!>.

2718 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
2719 like $@n instead of just @n so that the default %destructor/%printer
2720 logic doesn't see them as user-defined symbols.
2721 (symbol_is_dummy): Check for both forms of the name.
2722 * src/reader.c (packgram): Remove the `$' from each midrule symbol
2723 name for which the midrule value is referenced in any action.

2732 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
2734 (packgram): Before invoking grammar_rule_check on any rule, make sure
2735 all actions have already been scanned in order to set `used' flags.
2736 Otherwise, checking that a midrule's $$ is set will not always work
2737 properly because the midrule check must forward-reference the midrule's
2739 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
2742 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
2744 More improvements to the documentation of the prologue alternatives:
2745 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
2747 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
2748 some text to clarify the relative importance of the new directives and
2749 to show how these directives may be viewed as code labels.
2751 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
2753 Similar to the recently removed %before-header, add %code-top as the
2754 alternative to the pre-prologue. Mentioned at
2755 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.

2821 Fix testsuite for ./configure --enable-gcc-warnings:
2822 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.

2866 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
2867 variable was sometimes used without being initialized. This
2868 messed up the installation of the INSTALL file in some cases.
2870 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2872 * bootstrap (usage, main program, symlink_to_gnulib): Add option
2873 --copy. Inspired by a suggestion from Bruno Haible.
2875 2006-10-03 Jim Meyering <jim@meyering.net>
2877 * bootstrap: Undo last change to this file, since now gnulib-tool
2878 sticks with the automake default in generating dependencies.
2880 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2882 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

2960 that's now the caller's responsibility.
2961 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
2962 Set yychar = YYEOF if it's negative.
2963 * tests/actions.at (yylex): Abort if asked to read past EOF.

2973 Fix problems with translating English-language diagnostics.
2974 * bootstrap: Fix bug introduced in recent bootstrap changes, with

2983 Merge bootstrap changes from coreutils.
2985 2006-09-28 Jim Meyering <jim@meyering.net>
2987 Automatically generated dependencies are important even
2988 when all of the sources in a directory come from gnulib.
2989 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake

3028 to copies-of-gnulib.
3029 (cp_mark_as_generated, slurp, gnulib_files):
3030 Avoid making a copy if it's the same as the old version.
3031 (gnulib_files): Add support for this variable (used by Bison).
3033 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
3035 * src/getargs.c (usage): Rework to use conventions similar to
3036 coreutils, to make translation a bit easier and the code a bit
3037 smaller. Problem reported by Tim Van Holder.
3039 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
3041 Use some of gnulib's new modules, taken from coreutils.

3048 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.

3051 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
3053 (GNULIB_AUTOCONF_SNIPPET): Remove.
3054 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
3056 * lib/.cvsignore: Add inttypes_.h.
3057 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
3058 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
3059 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
3060 no-longer-necessary initializations.
3061 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.

3067 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
3068 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
3069 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
3070 * src/system.h: Include inttypes.h unconditionally, now that we
3071 use the inttypes module. Don't bother to include stdint.h, since
3072 inttypes.h now does that for us.

3075 * src/main.c: Likewise.
3076 * src/output.c: Likewise.
3077 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,

3081 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
3082 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
3084 * src/parse-gram.y (symbol_declaration): Don't put statements
3085 before declarations; it's not portable to C89.
3086 * src/scan-code.l (handle_action_at): Likewise.
3088 * src/scan-code.l: Always initialize braces_level; the old code
3089 left it uninitialized and therefore had undefined behavior.
3091 Don't attempt to redefine 'assert', since it runs afoul of
3092 systems where standard headers (mistakenly) include <assert.h>.
3093 Instead, define and use our own alternative, called 'aver'.
3094 * src/reader.c: Don't include assert.h, since we no longer
3096 * src/scan-code.l: Likewise.
3097 * src/system.h (assert): Remove, replacing with....
3098 (aver): New function, taking a bool arg. All uses changed.

3108 * src/getargs.h (push_parser): New declaration.
3109 * src/output.c (prepare): Add macro insertion of `push_flag'.
3110 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
3111 (prologue_declaration): Parse %push-parser.
3112 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
3113 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
3114 list of removed lines from the traces observed.
3115 (AT_CHECK_CALC_LALR): Added push parser tests.
3117 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
3119 * NEWS: Version 2.3a.
3120 * configure.ac (AC_INIT): Likewise.
3122 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
3123 "#define YYSTYPE int" that caused "make maintainer-check" to fail
3124 due to header ordering dependencies. I don't know why the #define
3127 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
3128 runtime cost when YYDEBUG is not defined, and so that some tests
3129 that used to fail now work. Problem and initial suggestion by
3131 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
3132 * data/glr.cc (b4_parser_class_name):
3133 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
3134 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
3135 (yydebug_) [YYDEBUG]: New member.
3136 (yycdebug_): Now defined only if YYDEBUG.
3137 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
3138 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
3139 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
3141 (debug_stream, set_debug_stream, debug_level, set_debug_level):
3142 Define only if YYDEBUG.
3143 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
3145 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
3146 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
3147 AT_CHECK_CALC_GLR_CC that are working now.
3149 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
3151 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
3152 We don't need them in glr.cc, and glr.c defines them.
3153 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
3154 assumes that defining it to anything is the same as defining
3155 it to 1. Problem reported by Paolo Bonzini.
3157 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
3159 * data/c.m4 (b4_null, b4_case): Define.
3160 * src/output.c (prepare_symbols): Use b4_null.
3161 (user_actions_output): Use b4_case.
3163 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
3165 * data/glr.c (b4_shared_declarations): Put start-header first,
3166 before any #includes that we generate, so that feature-test
3167 macros work. Problem reported by Michael Deutschmann in
3168 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
3169 * data/lalr1.cc: Likewise.
3170 * doc/bison.texinfo (Prologue): Document that feature-test macros
3171 should be defined before any Bison declarations.
3172 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
3173 that depend on location.hh after, not before, Bison decls, since
3174 we now include location.hh after the first user prologue.
3176 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
3177 Sander Brandenburg in
3178 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
3179 Also, fix minor white space and comment issues.
3180 (Prologue): Mention that it's better to define feature-test macros
3181 before Bison declarations. Problem reported by Michael Deutschmann.
3183 * README-cvs: Fix typo: "&" should be "&&". Problem reported
3185 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
3186 This adjusts to recent gnulib changes.
3188 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3190 Finish implementation of per-type %destructor/%printer. Discussed
3192 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
3194 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
3195 * NEWS (2.3+): Add a description of this feature to the default
3196 %destructor/%printer description.
3197 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
3198 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3199 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
3200 list node contains a semantic type.
3201 * src/symtab.c, src/symtab.h: Extend with a table that associates
3202 semantic types with their %destructor's and %printer's.
3203 (semantic_type_from_uniqstr, semantic_type_get,
3204 semantic_type_destructor_set, semantic_type_printer_set): New functions
3205 composing the public interface of that table.
3206 (symbol_destructor_get, symbol_destructor_location_get,
3207 symbol_printer_get, symbol_printer_location_get): If there's no
3208 per-symbol %destructor/%printer, look up the per-type before trying
3210 * tests/actions.at (Per-type %printer and %destructor): New test case.
3211 * tests/input.at (Default %printer and %destructor redeclared):
3212 Extend to check that multiple occurrences of %symbol-default in a
3213 single %destructor/%printer declaration is an error.
3214 (Per-type %printer and %destructor redeclared, Unused values with
3215 per-type %destructor): New test cases.
3217 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3219 Require default %destructor/%printer to be declared using
3220 %symbol-default instead of an empty symbol list, and start working on
3221 new per-type %destructor/%printer. Discussed at
3222 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
3223 * NEWS (2.3+): Add %symbol-default to example.
3224 * bison.texinfo (Freeing Discarded Symbols): Likewise.
3225 (Table of Symbols): Add entry for %symbol-default.
3226 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
3227 (generic_symlist, generic_symlist_item): New nonterminals for creating
3228 a list in which each item is a symbol, semantic type, or
3230 (grammar_declaration): Use generic_symlist in %destructor and %printer
3231 declarations instead of symbols.1 or an empty list.
3232 (symbol_declaration, precedence_declaration, symbols.1): Update actions
3233 for changes to symbol_list.
3234 * src/reader.c: Update for changes to symbol_list.
3235 * src/scan-code.l: Likewise.
3236 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
3237 * src/symlist.c, src/symlist.h: Extend such that a list node may
3238 represent a semantic type or a %symbol-default in addition to just an
3239 ordinary symbol. Add switched functions for setting %destructor's and
3241 * tests/actions.at, tests/input.at: Add %symbol-default to all default
3242 %destructor/%printer declarations.
3244 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
3246 Whether the default %destructor/%printer applies to a particular symbol
3247 isn't a question of whether the user *declares* that symbol (in %token,
3248 for example). It's a question of whether the user by any means
3249 *defines* the symbol at all (by simply using a char token, for
3250 example). $end is defined by Bison whereas any other token with token
3251 number 0 is defined by the user. The error token is always defined by
3252 Bison regardless of whether the user declares it with %token, but we
3253 may one day let the user define error as a nonterminal instead.
3254 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
3255 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
3256 the meaning of "user-defined".
3257 * tests/actions.at (Default %printer and %destructor for user-declared
3258 end token): Rename to...
3259 (Default %printer and %destructor for user-defined end token): ...
3262 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
3263 computation of whether to apply the default, don't maintain a list of
3264 every Bison-defined symbol. Instead, just check for a first character
3265 of '$', which a user symbol cannot have, and check for the error token.
3267 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
3269 Don't apply the default %destructor or %printer to the error token,
3270 $undefined, or $accept. This change fits the general rule that the
3271 default %destructor and %printer are only for user-declared symbols,
3272 and it solves several difficulties that are described in the new test
3274 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
3275 * tests/actions.at (Default %printer and %destructor are not for error
3276 or $undefined, Default %printer and %destructor are not for $accept):
3279 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
3281 Allow %start after the first rule.
3282 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
3283 when parsing the first rule.
3284 (check_and_convert_grammar): Search for it here after all grammar
3285 declarations have been parsed. Skip midrules, which have dummy LHS
3287 * src/symtab.c (symbol_is_dummy): New function.
3288 * src/symtab.h (symbol_is_dummy): Declare it.
3289 * tests/input.at (%start after first rule): New test.
3291 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3293 Redo some of the previous commit: add back the ability to use
3294 non-aliased/undeclared string literals since it might be useful to
3295 those declaring %token-table.
3296 * src/reader.c (check_and_convert_grammar): Undo changes in previous
3297 commit: don't worry about complaints from symbols_pack.
3298 * src/symtab.c (symbol_new, symbol_class_set,
3299 symbol_check_alias_consistency): Undo changes in previous commit: count
3300 each string literal as a new symbol and token, assign it a symbol
3301 number, and don't complain about non-aliased string literals.
3302 (symbols_pack): Since symbol_make_alias still does not decrement symbol
3303 and token counts but does still set aliased tokens to the same number,
3304 symbol_pack_processor now leaves empty slots in the symbols array.
3306 * tests/regression.at (Undeclared string literal): Remove test case
3307 added in previous commit since non-aliased string literals are allowed
3309 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
3310 remove unnecessary string literal declarations.
3311 * tests/sets.at (Firsts): Likewise.
3313 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3315 Don't allow an undeclared string literal, but allow a string literal to
3316 be used before its declaration.
3317 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
3318 symbols_pack complained.
3319 * src/symtab.c (symbol_new): Don't count a string literal as a new
3321 (symbol_class_set): Don't count a string literal as a new token, and
3322 don't assign it a symbol number since symbol_make_alias does that.
3323 (symbol_make_alias): It's not necessary to decrement the symbol and
3324 token counts anymore. Don't assume that an alias declaration occurs
3325 before any uses of the identifier or string, and thus don't assert that
3326 one of them has the highest symbol number so far.
3327 (symbol_check_alias_consistency): Complain if there's a string literal
3328 that wasn't declared as an alias.
3329 (symbols_pack): Bail if symbol_check_alias_consistency failed since
3330 symbol_pack asserts that every token has been assigned a symbol number
3331 although undeclared string literals have not.
3332 * tests/regression.at (String alias declared after use, Undeclared
3333 string literal): New test cases.
3334 (Characters Escapes, Web2c Actions): Declare string literals as
3336 * tests/sets.at (Firsts): Likewise.
3338 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
3340 In the grammar scanner, STRING_FINISH unclosed constructs and return
3341 them to the parser in order to improve error messages.
3342 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
3343 SC_BRACED_CODE, SC_PROLOGUE): Implement.
3344 * tests/input.at (Unclosed constructs): New test case.
3345 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
3348 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
3351 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
3353 Handle string aliases for character tokens correctly.
3354 * src/symtab.c (symbol_user_token_number_set): If the token has an
3355 alias, check and set its alias's user token number instead of its own,
3356 which is set to indicate the alias. Previously, every occurrence of
3357 the character token in the grammar overwrote that alias indicator with
3359 * tests/input.at (String aliases for character tokens): New test.
3361 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
3363 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
3365 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
3367 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
3368 to prevent failures when building on older platforms.
3369 Check for autopoint failure.
3370 Set XGETTEXT_OPTIONS to values that check for C format strings,
3371 so that translators are warned about them (this also helps
3372 prevent core dumps).
3374 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
3375 function, since it simplifies our code a bit.
3377 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
3378 rather than -W, so we don't get bogus warnings about sign comparisons.
3379 Add -Wpointer-arith, since that warning is useful (it reports code
3380 that does not conform to C89 and that some compilers reject).
3381 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
3382 since it's no longer needed.
3384 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
3386 Clean up scanners a bit.
3387 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
3388 definitions so gcc won't warn when obstack_for_string is unused.
3389 * src/scan-code.l: config.h and system.h are already #include'd by
3390 scan-code-c.c, so get rid of them here.
3391 * src/scan-gram.l: Likewise.
3392 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
3393 definitions rather than duplicating the rest of it.
3394 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
3396 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
3398 Suppress signed/unsigned comparison warnings for yycheck.
3399 * data/c.m4 (b4_safest_int_type): New macro.
3400 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
3401 a signed int type, cast it to b4_safest_int_type first.
3402 * data/yacc.c: Likewise.
3403 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
3406 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
3408 * doc/bison.texinfo: Fix some typos.
3410 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
3412 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
3413 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
3415 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
3416 the latest gnulib does this a different way.
3417 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
3418 translation was patched, so stop omitting it.
3420 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3422 Enable declaration of default %printer/%destructor. Make the parser
3423 use these for all user-declared grammar symbols for which the user does
3424 not declare a specific %printer/%destructor. Thus, the parser uses it
3425 for token 0 if the user declares it but not if Bison generates it as
3426 $end. Discussed starting at
3427 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
3428 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
3430 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
3431 * NEWS (2.3+): Mention.
3432 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
3433 declare a %destructor for a mid-rule's semantic value. It's just
3434 impossible to declare one specific to it.
3435 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
3436 code. Describe default %destructor form.
3437 * src/parse-gram.y (grammar_declaration): Parse default
3438 %printer/%destructor declarations.
3439 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
3440 and symbol_destructor_location_get rather than accessing the destructor
3441 and destructor_location members of struct symbol.
3442 (symbol_printers_output): Likewise but for %printer's.
3443 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
3445 * src/symtab.c (default_destructor, default_destructor_location,
3446 default_printer, default_printer_location): New static global
3447 variables to record the default %destructor and %printer.
3448 (symbol_destructor_get, symbol_destructor_location_get,
3449 symbol_printer_get, symbol_printer_location_get): New functions to
3450 compute the appropriate %destructor and %printer for a symbol.
3451 (default_destructor_set, default_printer_set): New functions to set the
3452 default %destructor and %printer.
3453 * src/symtab.h: Prototype all those new functions.
3454 * tests/actions.at (Default %printer and %destructor): New test to
3455 check that the right %printer and %destructor are called, that they're
3456 not called for $end, and that $$ and @$ work correctly.
3457 (Default %printer and %destructor for user-declared end token): New
3458 test to check that the default %printer and %destructor are called for
3459 a user-declared end token.
3460 * tests/input.at (Default %printer and %destructor redeclared, Unused
3461 values with default %destructor): New tests to check related grammar
3462 warnings and errors.
3464 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3466 Clean up handling of %destructor for the end token (token 0).
3467 Discussed starting at
3468 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
3470 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
3472 Make the skeletons consistent in how they pop the end token and invoke
3474 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
3475 state, which has token number 0, since this would invoke the
3476 %destructor for the end token.
3477 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
3478 until after shifting the end token, or else it won't be popped.
3479 * data/yacc.c (yyparse): Likewise.
3481 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
3482 it's the end token. Upon termination, destroy an unshifted lookahead
3483 even when it's the end token.
3484 * data/lalr1.cc (yy::parser::parse): Likewise.
3485 * data/yacc.c (yyparse): Likewise.
3487 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
3488 value warnings for the end token when the user gives the end token a
3491 * tests/actions.at (Printers and Destructors): Test all the above.
3493 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
3495 Update to latest gnulib and gettext versions.
3496 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
3498 (gnulib_files): Add m4/warning.m4. Don't worry about files
3499 overwritten by autopoint.
3500 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
3501 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
3503 Don't use autoreconf; instead, invoke autopoint etc. by hand,
3504 so that we can remove the intl files at a better time.
3505 (intl_files_to_remove): Remove aclocal.m4, since it gets
3506 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
3507 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
3508 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
3509 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
3510 Remove datarootdir hack; no longer needed.
3511 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
3512 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
3513 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
3515 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
3516 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
3518 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3520 * bootstrap: Adjust to today's change to gnulib-tool by invoking
3521 it with --assume-autoconf='latest-stable'.
3523 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
3525 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
3526 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
3528 * src/muscle_tab.h (muscle_grow): Replace the header comments with
3529 those from muscle_tab.c since the old ones are misleading.
3531 2006-07-13 Akim Demaille <akim@epita.fr>
3533 Support %define "KEY" {VALUE}.
3534 * src/scan-code.h, src/scan-code.l (translate_action)
3535 (translate_rule_action, translate_symbol_action, translate_code):
3536 Return char *, not const char *.
3537 * src/parse-gram.y (declaration): Rename as...
3538 (prologue_declaration): this.
3539 (string_content): Remove this nonterminal, use STRING.
3540 (braceless, content, content.opt): New nonterminal.
3542 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
3544 * src/scan-gram.l (getargs.h): Don't include it.
3546 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
3548 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
3549 rather than a for-loop that declares a local bool variable. This
3550 should work around a compatibility problem with a Cray x1e C++
3551 compiler reported by Hung Nguyen in
3552 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
3553 The for-loop was introduced in the 2004-11-17 change but I don't
3554 know why it was needed.
3556 2006-07-12 Akim Demaille <akim@epita.fr>
3558 * data/c.m4: Comment changes.
3560 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
3562 * src/complain.c (error_message, ERROR_MESSAGE): New.
3564 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
3565 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
3567 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
3569 * NEWS: Instead of %union, you can define and use your own union type
3570 YYSTYPE if your grammar contains at least one <type> tag.
3571 Your YYSTYPE need not be a macro; it can be a typedef.
3572 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
3573 (Union Decl, Decl Summary): Document this.
3574 * data/glr.c (YYSTYPE): Implement this.
3575 * data/glr.cc (YYSTYPE): Likewise.
3576 * data/lalr1.cc (YYSTYPE): Likewise.
3577 * data/yacc.c (YYSTYPE): Likewise.
3578 * src/output.c (prepare): Output tag_seen_flag.
3579 * src/parse-gram.y (declaration, grammar_declaration):
3580 Use 'union_seen' rather than 'typed' to determine whether
3581 %union has been seen, since grammars can now be typed without
3583 (symbol_declaration, type.opt, symbol_def):
3584 Keep track of whether a tag has been seen.
3585 * src/reader.c (union_seen, tag_seen): New vars.
3587 * src/reader.h (union_seen, tag_seen, typed): Likewise.
3588 * src/scan-code.l (untyped_var_seen): New variable.
3589 (handle_action_dollar): Adjust to above changes.
3590 (handle_action_dollar, handle_action_at):
3591 Improve overflow checking for outlandish numbers.
3592 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
3593 avoid new diagnostics generated by above changes.
3594 * tests/regression.at (YYSTYPE typedef): Add test to check
3595 for type tags without %union.
3597 * src/symlist.c (symbol_list_length): Return int, not unsigned
3598 int, since callers expect int. This may need to get revisited
3599 once we have proper integer overflow checking.
3601 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
3602 object is now static.
3604 * src/getargs.c (flags_argmatch): Return void, not int,
3605 to pacify ./configure --enable-gcc-warnings.
3607 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
3608 since last_string is already defined to FLEX_PREFIX (last_string).
3610 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
3612 Implement --warnings/-W.
3613 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
3615 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
3617 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
3618 (warnings_args, warnings_types): New.
3619 (getargs, short_options, long_options): Accept -W/--warnings.
3620 Sort the options by alphabetical order, upper case letter right
3621 before its lower case.
3623 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3625 Change %merge result type clash warnings to errors. Discussed at
3626 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
3627 * src/reader.c (record_merge_function_type): Use complain_at.
3628 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3629 declared later): Update test case results.
3631 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
3633 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
3634 to be in alphabetical order.
3635 (trace_args): Spelling fixes.
3637 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
3639 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
3640 so they don't collide with user-defined macros.
3641 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
3642 this was never guaranteed, and now that we're using gnulib stdint,
3643 which defines int_fast16_t to long int, the problem is exposed.
3645 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
3647 * data/c.m4 (b4_basename): Simplify a bit, since we don't
3648 need the full POSIX semantics (and weren't implementing them
3651 Adjust to Autoconf 2.60 and today's gnulib.
3652 * bootstrap (gnulib_modules): Add stdint.
3653 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
3654 no longer copies it.
3655 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
3656 since stdint needs the former and wcwidth (which is now required
3657 by mbswidth) needs the latter.
3658 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
3659 work around a compatibility glitch between gettext 0.14.6 and
3661 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
3662 Do not check for uintptr_t, since new stdint module does the right
3664 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
3665 Add stdint.h, stdint_.h, wcwidth.h.
3666 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
3667 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
3668 stdint.m4, wchar_t.m4, wcwidth.m4.
3669 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
3670 usual order for ../lib/*.h files.
3671 (file_name_split): Use last_component, not base_name, to adjust
3673 * src/parse-gram.h: Include <strverscmp.h> in the usual order
3674 for ../lib/*.h files.
3675 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
3676 Define unconditionally, since we now assume the stdint module.
3677 * src/scan-skel.l: Include <dirname.h>.
3678 (BASE_QPUTS): Use last_component, not base_name.
3679 * src/system.h: Include <unlocked-io.h> in the usual order
3680 for ../lib/*.h files. Include <stdint.h> unconditionally,
3681 since we now use the stdint module.
3682 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
3683 HAVE_UINTPTR_T, since we now use the stdint module.
3684 (base_name): Remove decl, since files now include <dirname.h>
3687 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
3689 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
3691 * data/yacc.c, data/glr.c, data/location.cc: Use them.
3692 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
3694 * tests/calc.at: Adjust.
3696 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
3698 * data/c.m4 (b4_basename): New.
3699 (b4_syncline): Also output the location of its invocation (from
3701 (b4_user_action, b4_define_user_action, b4_user_actions)
3702 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
3703 (b4_user_stype): New.
3704 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
3706 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
3708 In the grammar file, the first column is 1 not 0 on the first line as
3709 on every other line.
3710 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
3711 * tests/input.at (Torturing the Scanner): Update output.
3713 * src/scan-gram.l (scanner_cursor): Declare it static.
3715 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
3717 In warnings, say "previous declaration" rather than "first
3719 * src/symtab.c (redeclaration): Do that here.
3720 * src/reader.c (record_merge_function_type): In the case of a result
3721 type clash, report the previous declaration rather than the very first
3722 one in the grammar file.
3723 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3724 declared later): Add a third declaration to check this behavior.
3725 * tests/input.at (Incompatible Aliases): Update output.
3727 2006-06-27 Akim Demaille <akim@epita.fr>
3729 * doc/Doxyfile.in: New.
3730 * doc/Makefile.am: Use it.
3731 * src/lalr.h, src/symtab.h: Initial doxygenation.
3733 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3735 Don't miss %merge result type warnings just because the LHS types are
3736 declared after the %merge. This continues the effort of the previous
3738 * src/reader.c (get_merge_function): Don't set the merger type yet.
3739 (record_merge_function_type): New function for setting the merger type
3740 and checking for clashes.
3741 (grammar_current_rule_merge_set): Set the location of the %merge for
3743 (packgram): Invoke record_merge_function_type for each rule now that
3744 all symbol type declarations have been parsed.
3745 * src/reader.h (merger_list.type_declaration_location): New member
3746 storing the location of the first %merge from which the type for this
3747 merging function was derived.
3748 * src/symlist.h (symbol_list.merger_declaration_location): New member
3749 storing the location of a rule's %merge, if any.
3750 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3751 declared later): New test to catch the error fixed by the above patch.
3753 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3755 Get action warnings (grammar_rule_check) right even when symbol
3756 declarations appear after the rules. Discussed at
3757 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
3759 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
3760 Don't mistake the type of $$ in a midrule to be that of its parent
3762 * src/reader.c (grammar_current_rule_end): Don't invoke
3763 grammar_rule_check yet since not all symbol declarations may have been
3765 (grammar_midrule_action): Likewise.
3766 Don't record whether the midrule's $$ has been used yet since actions
3767 haven't been translated yet.
3768 Record the midrule's parent rule and its RHS index within the parent
3770 (grammar_current_rule_action_append): Don't translate the action yet
3771 since not all symbol declarations may have been parsed yet and, thus,
3772 warnings about types for $$, $n, @$, and @n can't be reported yet.
3773 (packgram): Translate the action and invoke grammar_rule_check now that
3774 all symbol declarations have been parsed.
3775 * src/scan-code.l (handle_action_dollar): Now that this is invoked
3776 after parsing the entire grammar file, the symbol list here in the case
3777 of a midrule is actually the midrule's empty RHS, so reference its
3778 parent rule's RHS where necessary.
3779 On the other hand, now that you can already know it's a midrule, you
3780 aren't forced to think $$ has the same type as its parent rule's $$.
3781 (handle_action_at): In the case of a midrule, reference the parent rule
3783 * src/symlist.c (symbol_list_new): Initialize new midrule-related
3785 (symbol_list_length): Now that this is invoked after all rules have
3786 been parsed, a NULL symbol (rather than a NULL symbol list node)
3787 terminates a rule. symbol_list_print already does this correctly.
3788 * src/symlist.h (symbol_list.midrule_parent_rule,
3789 symbol_list.midrule_parent_rhs_index): New members so that midrules can
3790 remember their relationships with their parents.
3791 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
3792 fixed by the above patch.
3793 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
3795 (Unused values): ... this old test case and...
3796 (Unused values before symbol declarations): ... this new test case.
3797 This one is the same as `Unused values' except that all symbol
3798 declarations appear after the rules in order to catch the rest of the
3799 errors fixed by the above patch.
3801 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3804 * src/reader.c (current_rule): Declare it static since it's no longer
3805 used outside this file.
3806 (grammar_current_rule_action_append): Remove redundant arguments from
3807 translate_rule_action invocation.
3808 * src/reader.h (current_rule): Remove this unused extern.
3809 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
3810 * src/scan-code.l (translate_rule_action): Likewise.
3812 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
3814 Clean up yesterday's patch.
3815 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
3817 * src/reader.c (grammar_current_rule_action_append): ... here for
3818 consistency with grammar_current_rule_symbol_append.
3819 * tests/regression.at (Braced code in declaration in rules section):
3820 Make yyerror and yylex static as usual.
3822 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
3824 Fix bug that mistakes braced code in a declaration in the rules section
3825 to be a rule action. Mentioned at
3826 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
3827 * src/scan-gram.l: Move midrule action detection from the start of the
3828 scanning of any braced code to...
3829 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
3830 action. For readability, use $2 and @2 rather than the equivalent
3832 * tests/regression.at (Braced code in declaration in rules section):
3833 New test to catch the error fixed by the above patch.
3835 Work on code readability some.
3836 * src/scan-code.l (current_rule): Get rid of this misleading and
3837 redundant declaration: it's actually extern'ed in reader.h.
3838 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
3839 translate_action): Add a rule argument and use it instead of the global
3841 (translate_rule_action): This already receives current_rule through an
3842 argument, so pass it on to translate_action instead of assigning
3843 current_rule to current_rule.
3844 (translate_symbol_action, translate_code): Pass rule = NULL to
3847 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
3849 Rename %before-definitions to %start-header and %after-definitions to
3850 %end-header. Don't use these declarations to separate pre-prologue
3851 blocks from post-prologue blocks. Add new order-independent
3852 declarations %before-header and %after-header as alternatives to the
3853 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
3854 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
3855 * NEWS (2.3+): Update for these changes.
3856 * data/glr.c (b4_before_definitions): Update to...
3857 (b4_start_header): ... this.
3858 (b4_after_definitions): Update to...
3859 (b4_end_header): ... this.
3860 * data/glr.cc: Likewise.
3861 * data/lalr1.cc: Likewise.
3862 * data/yacc.c: Likewise.
3863 * doc/bison.texinfo (The prologue): Update names, and replace remaining
3864 prologue blocks with %*-header declarations.
3865 (Calc++ Parser): Likewise.
3866 (Decl Summary): Update names.
3867 (Table of Symbols): Update description.
3868 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
3869 (PERCENT_END_HEADER): ... this.
3870 (PERCENT_BEFORE_DEFINITIONS): Update to...
3871 (PERCENT_START_HEADER): ... this.
3872 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
3873 (declaration): Update token names and m4 macro names.
3874 When parsing %end-header and %start-header, invoke translate_code
3875 before muscle_code_grow, and no longer set global booleans to remember
3876 whether these declarations have been seen.
3877 Parse new %after-header and %before-header.
3878 * src/reader.c (before_definitions, after_definitions): Remove.
3879 (prologue_augment): Accept a new bool argument to specify whether to
3880 augment the pre-prologue or post-prologue.
3881 * src/reader.h (before_definitions, after_definitions): Remove these
3883 (prologue_augment): Add new bool argument.
3884 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
3885 (PERCENT_END_HEADER): ... this.
3886 (PERCENT_BEFORE_DEFINITIONS): Update to...
3887 (PERCENT_START_HEADER): ... this.
3888 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
3889 * tests/actions.at (Printers and Destructors): Update names.
3891 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
3893 Add comparison operators for C++ location classes. Discussed at
3894 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
3895 * data/c++.m4 (b4_define_location_comparison): New boolean %define
3896 declaration indicating whether filename_type has an operator==. If
3897 filename_type is `std::string', it defaults to `1', `0' otherwise.
3898 * data/location.cc: Iff b4_define_location_comparison is `1', add
3899 operator== and operator!= for class position and for class location.
3902 * src/scan-action.l: Remove unused file.
3903 * src/symtab.c (symbol_printer_set): Use printer_location not
3904 destructor_location.
3905 * src/symtab.h (struct symbol): Replace incorrect source comment for
3907 * tests/input.at (Incompatible Aliases): Update output with correct
3910 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
3912 Don't put the pre-prologue in the header file. For the yacc.c code
3913 file and the glr.c header and code files, move the pre-prologue before
3914 the token definitions. Add new %before-definitions and
3915 %after-definitions to declare code that will go in both the header file
3916 and code file. Discussed at
3917 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
3918 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
3920 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
3921 * NEWS (2.3+): Describe these changes.
3922 * data/glr.c (b4_pre_prologue): Move from within to before...
3923 (b4_shared_declarations): ... this.
3924 Add new b4_before_definitions before b4_token_enums.
3925 Add new b4_after_definitions at the end.
3926 * data/glr.cc (b4_pre_prologue): Replace with...
3927 (b4_before_definitions): ... this in the header file.
3928 (b4_after_definitions): New near the end of the header file.
3929 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
3930 code file right before including the header file.
3931 (b4_before_definitions): New in the previous position of
3932 b4_pre_prologue in the header file.
3933 (b4_after_definitions): New near the end of the header file.
3934 * data/yacc.c: Clean up some m4 quoting especially in the header file.
3935 (b4_token_enums_defines): In the code file, move to right before
3936 YYSTYPE for consistency with the header file.
3937 (b4_before_definitions): New right before b4_token_enums_defines in
3938 both the header and code file.
3939 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
3940 header and code file.
3941 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
3942 of prologues for %union dependencies.
3943 (Decl Summary): In %defines description, mention the effect of
3944 %before-definitions and %after-definitions on the header file.
3945 (Calc++ Parser): Forward declare driver in a %before-definitions rather
3946 than in the pre-prologue so that make check succeeds.
3947 (Table of Symbols): Add entries for %before-definitions and
3949 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
3950 %before-definitions.
3951 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
3952 (declaration): Parse those declarations and append to
3953 b4_before_definitions and b4_after_definitions, respectively.
3954 * src/reader.c (before_definitions, after_definitions): New bools to
3955 track whether those declarations have been seen.
3956 (prologue_augment): Add to the post-prologue if %union,
3957 %before-definitions, or %after-definitions has been seen.
3958 * src/reader.h (before_definitions, after_definitions): New extern's.
3959 * src/scan-gram.l: Scan the new declarations.
3960 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
3961 prologue block in a %before-definitions or a %after-definitions based
3962 on whether the %union is declared.
3963 * tests/regression.at (Early token definitions with --yacc, Early token
3964 definitions without --yacc): Move tests for token definitions into the
3965 post-prologue since token names are no longer defined in the

3970 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
3971 (symbol_get): Use it.

3974 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
3976 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
3977 build succeeds when configured with --enable-gcc-warnings.
3979 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3981 * src/parse-gram.y (char_name): New function.
3982 (CHAR, STRING, string_content): For %printer, properly escape.
3983 (ID): Prefer fputs to fprintf.
3984 (id): Reindent to be consistent with other rules.
3985 Properly quote char.
3987 The Translation Project changed its way of publishing translations
3988 to maintainers. I haven't received any responses to my request
3989 for supporting the old way, or for documenting the new way. I
3990 have modified 'bootstrap' to use screen scraping
3991 (in this case, HTML scraping). This is unreliable and inelegant,
3992 but I don't see any better way. Yuck.
3993 * bootstrap (TP_URL, WGET_COMMAND): New vars.
3994 (get_translations): New function, which uses HTML scraping to
3995 deduce locations of latest translations.
3996 Use this function to grab both bison and bison-runtime .po files.
3997 Don't bother priming the pump for the runtime-po domain any more,
3998 as it's now translated better than bison is.
4000 2006-06-19 Akim Demaille <akim@epita.fr>
4002 * src/scan-gram.l: No longer "parse" things after `%union' until
4003 `{'. Rather, return a single "%union" token.
4004 No longer make symbols: return strings, and leave the conversion
4005 to symbols to the parser.
4006 (SC_PRE_CODE, token_type): Remove.
4007 * src/parse-gram.y (%union): New field `character'.
4010 (ID, ID_COLON): Now that the scanner no longer makes them
4011 identifiers, adjust all uses to invoke symbol_get.
4012 (id_colon): New, wraps the conversion from string to symbol.
4013 (%union): Accept a possible union_name.
4014 (symbol): Now can be a char.
4015 * data/c.m4 (b4_union_name): Leave a default value.
4016 * data/glr.c, data/yacc.c: Use it.
4018 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
4020 For associating token numbers with token names for "yacc.c", don't use
4021 #define statements unless `--yacc' is specified; always use enum
4022 yytokentype. Most important discussions start at:
4023 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,

4032 on token name definitions.
4033 * src/getargs.c (usage): Capitalize `Yacc' in English.
4034 * src/output.c (prepare): Define b4_yacc_flag.
4035 * tests/regression.at (Early token definitions): Test that tokens names
4036 are defined before the pre-prologue not just before the post-prologue.
4037 Remove this test case and copy to...
4038 (Early token definitions with --yacc): ... this to test #define's.
4039 (Early token definitions without --yacc): ... and this to test enums.
4041 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
4043 * NEWS: Reword the post-2.3 change to not be so optimistic about
4044 removing the old "look-ahead" spelling.
4045 Update previous look-ahead/lookahead change reports.
4046 * REFERENCES: look-ahead -> lookahead (since that's
4047 what he actually wrote).
4048 * doc/refcard.tex: look ahead -> lookahead,
4049 look-ahead -> lookahead
4051 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
4053 For consistency, use `lookahead' instead of `look-ahead' or
4054 `look_ahead'. Discussed starting at

4128 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4130 * TODO: Add request from Nelson H. F. Beebe to be able to install
4131 Bison without installing the yacc script.
4133 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
4135 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
4136 and yytext if they're already #define'd.
4137 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
4138 * src/scan-code-c.c: ... here.
4139 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include

4144 Get Bison to build again when configured with --enable-gcc-warnings.
4145 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
4147 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
4148 loc argument as it shadows a global.
4149 * src/scan-gram.l: Remove stray comma that prevents boundary_set
4152 * src/.cvsignore: Add scan-code.c.
4154 2006-06-07 Akim Demaille <akim@epita.fr>
4156 * src/scan-gram.l: Move the "add a trailing ; to actions" code
4158 * src/scan-code.l: here.
4159 * tests/input.at (Torturing the Scanner): Fix another location
4162 2006-06-07 Akim Demaille <akim@epita.fr>
4164 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
4166 2006-06-06 Akim Demaille <akim@epita.fr>
4168 Extract the parsing of user actions from the grammar scanner.
4169 As a consequence, the relation between the grammar scanner and
4170 parser is much simpler. We can also split "composite tokens" back
4172 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
4173 * src/scan-gram.l (add_column_width, adjust_location): Move to and
4175 * src/location.h, src/location.c (add_column_width)
4176 (location_compute): these.
4177 Fix the column count: the initial column is 0.
4178 (location_print): Be robust to ending column being 0.
4179 * src/location.h (boundary_set): New.
4180 * src/main.c: Adjust to scanner_free being renamed as
4182 * src/output.c: Include scan-code.h.
4183 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
4185 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
4186 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
4187 which is now, again, a separate token.
4188 Adjust all dependencies.
4189 Whereever actions with $ and @ are used, use translate_code.
4190 (action): Remove this nonterminal which is now useless.
4191 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
4192 (grammar_current_rule_action_append): Use translate_code.
4193 (packgram): Bound check ruleno, itemno, and rule_length.

4196 (scanner_initialize, scanner_free, scanner_last_string_free)
4197 (gram_out, gram_lineno, YY_DECL_): Move to...

4199 (YY_DECL): Rename as...
4201 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
4202 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
4203 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
4204 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
4205 Move these declarations, and...
4206 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):

4209 * src/scan-gram.l (rule_length, rule_length_overflow)
4210 (increment_rule_length): Remove.
4211 (last_braced_code_loc): Rename as...
4212 (gram_last_braced_code_loc): this.
4213 Adjust to the changes of the parser.
4214 Move all the handling of $ and @ into...
4215 * src/scan-code.l: here.
4216 * src/scan-gram.l (handle_dollar, handle_at): Remove.
4217 (handle_action_dollar, handle_action_at): Move to...
4218 * src/scan-code.l: here.

4229 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4231 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4232 Use Akim's wording from
4233 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
4235 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4237 Between Bison releases, manually append `+' to the previous Bison
4238 release number, and use that as a signal to automatically print the
4239 ChangeLog's CVS Id keyword from --version. Discussed starting at
4240 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
4241 * ChangeLog: Add Id header.
4242 * configure.ac (AC_INIT): Append `+' to `2.3'.
4243 * src/.cvsignore: Add revision.c.
4244 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
4245 (BUILT_SOURCES): Add revision.c.
4246 (revision.c): New target rule. This file defines a new global variable
4247 named revision. It initializes it with either the Id from ChangeLog
4248 or, if VERSION doesn't contain `+', with the empty string.
4249 * src/getargs.c (version): Print the value of revision.
4250 * src/revision.h: Extern revision.
4252 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4254 * NEWS: Version 2.3.
4255 * configure.ac (AC_INIT): Likewise.
4257 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4259 * data/glr.c (YYRECOVERING): Define to be a function-like macro
4260 with no arguments, not as an object-like macro. This is for
4261 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
4262 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
4263 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
4266 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
4268 * src/getargs.c (usage): Back out yesterday's modification of the
4269 --help output so that we don't have to wait for translation before
4272 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4274 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
4275 Problem reported by Akim Demaille.
4277 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4279 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4281 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4283 * data/yacc.c (yy_reduce_print): Omit trailing white space in
4284 generated source code. Problem reported by Frans Englich in
4285 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
4287 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
4289 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
4290 shell, not within 'make', so that 'make' by an ordinary builder
4291 (using GNU make) does not worry about configuring gzip. This also
4292 works around a bug reported independently by Keith Thompson and by
4293 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
4294 stderr rather than stdout, messing up the build logs.
4296 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4298 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
4299 to make sure that YYID will never be unused. This fixes a 'make
4300 maintainer-check' failure caused by the recent changes to the 'Trivial
4301 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
4303 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
4305 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4307 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
4308 state before an empty RHS is always resolved here. Only the location
4309 of that state is guaranteed to be resolved, and that's enough. This
4310 fixes the remaining bug reported by Derek M. Jones in
4311 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4312 * tests/glr-regression.at (Uninitialized location when reporting
4313 ambiguity): Test the above case.
4314 Also, the embedded comments in this test case claim it checks the case
4315 of an empty RHS that has inherited the initial location. However, the
4316 corresponding LHS was already resolved, so yyresolveLocations didn't
4317 actually have reason to modify it. Fix this by forcing
4318 nondeterministic operation at the beginning of the parse.
4320 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4322 * data/c.m4 (b4_yy_symbol_print_generate):
4323 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
4324 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
4325 of the bugs reported today by Derek M Jones in
4326 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4327 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
4328 defined to be a type name without parens or brackets.
4329 (Location Type): Similarly for YYLTYPE.
4330 * tests/regression.at (Trivial grammars): Put in a test for this
4331 bug that will be caught by 'make maintainer-check' (though not,
4332 alas, by 'make check' unless your compiler is picky).
4334 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4336 * NEWS: Version 2.2.
4337 * configure.ac (AC_INIT): Likewise.
4339 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
4341 * data/glr.c (yyreportTree): Make room in yystates for the state
4342 preceding the RHS. This fixes the segmentation fault reported by Derek
4344 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
4345 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
4346 to the user. Reported for yyreportTree by Derek M. Jones later in the
4348 * THANKS: Add Derek M. Jones.
4349 Update my email address.
4350 Fix typo in Steve Murphy's name.
4352 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4354 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
4355 checking against YYLAST that caused the parser to miss a potential
4356 alternative in its diagnostic.
4357 Problem reported by Maria Jose Moron Fernandez in
4358 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
4359 * data/lalr1.cc (yysyntax_error_): Likewise.
4360 * data/yacc.c (yysyntax_error): Likewise.
4361 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
4362 tokens, in case we run into an older C compiler.
4363 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
4364 Use them to check for the off-by-one error fixed above.
4366 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
4367 YYSIZE_T, not size_t.
4368 * tests/regression.at (Trivial grammars): New test, to catch
4369 the error fixed by the above patch.
4371 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4373 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
4375 Reported by Steve Murphy.
4377 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4379 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
4380 * data/glr.cc: b4_location_flag is now b4_locations_flag.
4382 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4384 Implement --trace=m4.
4385 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
4386 * src/output.c (output_skeleton): When set, pass -dV to m4.
4388 Factor the handling of flags in m4.
4389 * src/output.c (prepare): Rename the muscle names debug, defines,
4390 error_verbose to debug_flag, defines_flag, error_verbose_flag.
4391 * data/c.m4: Adjust.
4392 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
4393 Use b4_define_flag_if to define other b4_FLAG_if macros.
4394 (b4_location_if): As a consequence, rename as...
4395 (b4_locations_if): this, for consistency.
4396 Adjust all the skeletons.
4398 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4400 * etc/bench.pm: Shorten bench names.
4402 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4404 * src/output.h, src/output.c (error_verbose): Move to...
4405 * src/getargs.h, src/getargs.c: here.
4407 Adjust dependencies.
4409 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4411 * data/c.m4 (b4_copyright): Put the special exception for Bison
4412 skeletons here, so we don't have to put it in each skeleton. All
4413 uses changed. Suggested by Akim Demaille. Also, wrap the
4414 copyright notice, in case it is longer than 80 columns. Replace
4415 comma by newline after title.
4417 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4419 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
4420 incompatibility, not a bug. Mention that it wasn't fixed as of
4423 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4425 * examples/extexi: Enforce the precedence of concatenation over
4427 Reported by Tommy Nordgren.
4429 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4431 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
4432 with the member "token".
4433 Reported by Martin Nylin.
4435 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
4437 * data/glr.c: Switch to Bison 2.2 special-exception language in
4438 the copyright notice. Use more-regular format for titles and
4440 * data/glr.cc: Likewise.
4441 * data/location.cc: Likewise.
4442 * data/yacc.cc: Likewise.

4444 * NEWS: likewise. Upgrade version to 2.2.
4446 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
4448 * data/glr.cc: Remove dead code.
4450 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4452 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
4453 that variable and the line breaks the bootstrap. Problem reported
4454 by Juan M. Guerrero.
4456 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
4458 * doc/bison.texinfo (Multiple start-symbols): New.
4460 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
4462 * etc/README, etc/bench.pl: New.
4464 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
4466 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
4468 Reported by Mickael Labau.
4469 * tests/input.at (Torturing the Scanner): Test it.
4471 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
4473 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
4474 Problem reported by Bob Rossi.
4476 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
4478 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
4479 and didn't really work.
4480 For the index, use @ifnotinfo, not @iftex.
4481 Minor cleanups of spacing and terminology.
4483 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4485 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
4486 of AT_NAME_PREFIX when %name-prefix is not used.
4488 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4490 Apply --prefix to C++ skeletons too: they change the namespace.
4491 The test suite already exercize these cases.
4492 * data/c++.m4 (b4_namespace): New.
4493 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
4494 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
4495 * data/yacc.c, data/glr.c: Remove a useless `[]'.
4496 * doc/bison.texinfo: Document it.
4497 (Option Cross Key): Use @multitable in all formats. It looks
4498 nicer, even in TeX outputs.
4499 (Rules): Use the same code whatever the output type is.
4500 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
4501 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.

4519 * doc/bison.texinfo (Calc++ Scanner): Use it.
4521 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
4523 Fix two nits reported by twlevo, plus one more that I discovered.
4525 * src/assoc.h (assoc_to_string): Give a name to the arg, as
4526 this is the usual Bison style.
4527 * src/location.h (location_print): Likewise.
4529 * src/reader.h (token_name): Likewise.
4531 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
4533 Fix some nits reported by twlevo.
4534 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
4535 and "POSIX". Use more-modern syntax for URLs. Mention C++
4536 and ask for Java. Don't hardwire OS version numbers. Add
4538 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
4539 * src/conflicts.c (solved_conflicts_obstack): Now static.
4541 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
4543 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
4544 page. Say "you can use it" not "you may use it" as on the web page;
4545 we're describing capabilities not granting permission.
4547 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
4549 * data/glr.c (yyresolveLocations): Rename local variables to avoid
4550 shadowing warnings. Use usual patter for iterating through RHS.
4551 * tests/glr-regression.at
4552 (Uninitialized location when reporting ambiguity):
4553 Modify yylex so that it uses its argument, rather than trying
4554 to rely on ARGSUSED (which doesn't work for gcc with warnings).
4555 const char -> char const.
4557 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
4558 Don't use tabs inside commands; it messes up 'ps'.
4559 Problem reported by twlevo.
4561 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
4563 * tests/glr-regression.at (Uninitialized location when reporting
4564 ambiguity): New test case.
4565 * data/glr.c (yyresolveLocations): New function, which uses
4567 (yyresolveValue): Invoke yyresolveLocations before reporting an
4569 * doc/bison.texinfo (Default Action for Locations): Note
4570 YYLLOC_DEFAULT's usage for ambiguity locations.
4571 (GLR Semantic Actions): Cross-reference those notes.
4573 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
4575 * tests/glr-regression.at (Leaked semantic values when reporting
4576 ambiguity): Remove unnecessary union and type declarations.
4577 (Leaked lookahead after nondeterministic parse syntax error): New test
4579 * data/glr.c (yyparse): Check for zero stacks remaining before
4580 attempting to shift the lookahead so that you don't lose it.
4582 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
4584 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
4585 * tests/glr-regression.at (Leaked semantic values when reporting
4586 ambiguity): New test case.
4587 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
4588 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
4589 now unnecessary yystackp parameter.
4590 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
4591 destructors can be called.
4593 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
4594 in existing testcases.
4596 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
4598 Don't leak semantic values for parent RHS when a user action cuts the
4599 parser, and clean up related code a bit.
4600 * tests/glr-regression.at (Leaked merged semantic value if user action
4601 cuts parse): Rename to...
4602 (Leaked semantic values if user action cuts parse): ... this. Add check
4603 for leaked parent RHS values.
4604 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
4605 between an unresolved state (non-empty chain of semantic options) and
4606 an incomplete one (signaled by an empty chain).
4607 (yyresolveStates): Document the interface. Move all manipulation of a
4608 successfully or unsuccessfully resolved yyGLRState to...
4609 (yyresolveValue): ... here so that yyresolveValue always leaves a
4610 yyGLRState with consistent data and thus is easier to understand.
4611 Remove the yyvalp and yylocp parameters since they are always just
4612 taken from the yys parameter. When reporting a discarded merged value
4613 in debugging output, note that it is incompletely merged. Document the
4615 (yyresolveAction): If resolving any of the RHS states fails, destroy
4616 them all rather than leaking them. Thus, as long as user actions are
4617 written to clean up the RHS correctly, yyresolveAction always cleans up
4618 the RHS of a semantic option. Document the interface.
4620 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
4622 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
4623 led to a segmentation fault in GNU Pascal. Problem reported
4626 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
4628 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
4629 mid-rule action inside a nonterminal symbol in order to declare a
4630 destructor for its semantic value.
4632 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
4634 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !

4636 __cplusplus && ! defined _STDLIB_H && !
4637 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
4638 defined free))]: Include <stdlib.h> rather than rolling our own
4639 declarations of malloc and free, to avoid problems with
4640 incompatible declarations (using 'throw') C++'s stdlib.h. This
4641 should fix Debian bug 340012

4653 * NEWS: Version 2.1a.
4654 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
4655 since C99 requires this.
4657 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
4659 * m4/c-working.m4: New file.
4660 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
4662 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
4664 * Makefile.maint: Merge from coreutils.
4666 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
4668 More portability fixes for problems summarized by Nelson H. F. Beebe.
4670 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
4671 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
4672 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
4673 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

4679 More portability fixes for problems summarized by Nelson H. F. Beebe.
4681 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
4682 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
4684 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
4685 nodist_PROGRAMS, since we don't need to actually compile the
4686 example if we're just doing a plain 'make'. This avoids bothering
4687 the installer unnecessarily about problems due to weird C++

4692 More portability fixes for problems summarized by Nelson H. F. Beebe.
4694 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
4695 than #include "...", and compile with -I'.'. The old method was
4696 not portable, according to Posix and the C standard, and it does
4697 not work with Sun C 5.7, where previous #line directives affect
4698 the working directory used in later #include "..." directives.

4709 '#include <map>' works and that you can apply ++ to iterators.
4711 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
4713 Work around portability problems summarized by Nelson H. F. Beebe in

4717 that '#include <string>' works.
4719 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
4720 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
4721 "warning: sorry: semantics of inline function static data `const
4722 unsigned char translate_table[262]' are wrong (you'll wind up with
4725 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
4726 or, xor to not_, and_, or_, and xor_, respectively. This works
4727 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
4728 random system header somewhere that includes the equivalent of
4731 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
4732 -E" works; it apparently doesn't work with PathScale EKO Compiler
4735 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
4737 During deterministic GLR operation, user actions should be able to
4738 influence the parse by changing yychar. To make this easier to fix and
4739 to make glr.c easier to evolve in general, don't maintain yytoken in
4740 parallel with yychar; just compute yytoken when needed.
4741 * tests/glr-regression.at (Incorrect lookahead during deterministic
4742 GLR): Check that setting yychar in a user action has the intended
4744 * data/glr.c (yyGLRStack): Remove yytokenp member.
4745 (yyclearin): Don't set *yytokenp.
4746 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
4747 yychar rather than *yytokenp to determine the current lookahead.
4748 Compute yytoken locally when needed.
4749 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
4752 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
4753 after `--report' documentation.

4764 all the test at once. This makes the output easier to read in the
4767 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
4768 got from <http://bro-ids.org/download.html>. The bug is that
4769 when two actions appeared in succession, the second one was
4770 scanned before the first one was added to the grammar rule
4771 as a midrule action. Bison then output the incorrect warning
4772 "parse.y:905.17-906.36: warning: unused value: $3".
4773 * src/parse-gram.y (BRACED_CODE, action): These are no longer
4774 associated with a value.
4775 (rhs): Don't invoke grammar_current_rule_action_append.
4776 (action): Invoke it here instead.
4777 * src/reader.c (grammar_midrule_action): Now extern.
4778 (grammar_current_rule_action_append): Don't invoke
4779 grammar_midrule_action; that is now the scanner's job.
4780 * src/reader.h (last_string, last_braced_code_loc):
4781 (grammar_midrule_action): New decls.
4782 * src/scan-gram.l (last_string): Now extern, sigh.
4783 (last_braced_code_loc): New extern variable.
4784 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
4785 rule already has an action.
4786 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
4787 * tests/input.at (AT_CHECK_UNUSED_VALUES):
4788 Add some tests to check that the above changes fixed the bug.
4790 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
4792 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
4793 All used changed. Check whether the symbol has a destructor,
4794 not whether it is typed.
4795 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
4796 that the values are still reported as unused. All line numbers

4813 user can override the types.

4843 since we don't want to insist on a version number at the start
4844 of the changelog every time.
4845 * Makefile.maint: Sync from coreutils a bit better.

5034 in the yychar entry.
5035 In the yychar entry, remove mention of the local yychar case (pure
5036 parser) since this is irrelevant information when writing semantic
5037 actions and since it's already discussed in `Table of Symbols' where
5038 yychar is otherwise described as an external variable.
5039 In the yychar entry, don't call it the `current' look-ahead since it
5040 isn't when semantic actions are deferred.
5041 In the yychar and yyclearin entries, add note about deferred semantic
5043 Add yylloc and yylval entries discussing look-ahead usage.
5044 (Look-Ahead Tokens): When discussing yychar, don't call it the

5069 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
5070 from which the RHS is taken. Set the lookahead members of the new

5073 yyaddDeferredAction.
5074 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

5085 (Incorrect lookahead during nondeterministic GLR): New test case.
5087 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

5099 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5101 * data/glr.c (yyresolveValue): When merging semantic options, if at
5102 least one user action succeeds but a later one cuts the parse, then
5103 destroy the semantic value before returning rather than leaking it.
5104 (yyresolveStates): If a user action cuts the parse and thus
5105 yyresolveValue fails, ignore the (unset) semantic value rather than
5106 corrupting the yyGLRState, and empty the semantic options list since
5107 the user actions should have called all necessary destructors.
5108 Simplify code with YYCHK.
5109 * tests/glr-regression.at (Corrupted semantic options if user action
5110 cuts parse): New test case.
5111 (Undesirable destructors if user action cuts parse): New test case.

5385 using djunpack.bat and fnchange.lst.
5387 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
5389 * bootstrap (build_cvs_prefix): Remove; unused.
5390 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
5391 when getting gnulib.

5409 sed out the final state number.
5411 Work around portability problem on Solaris 10: flex-generated
5412 files include <stdio.h> before <config.h>, which messes up
5413 because the latter defines __EXTENSIONS__. Address the problem
5414 by creating two new little files that include <config.h> first,
5415 then include the flex-generated files. Rewrite everyone else
5416 to include <config.h> first, as well.
5417 * lib/timevar.c: Always include "config.h".
5418 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

5491 * NEWS: Document the following change.
5492 * data/yacc.c: Say "parser skeleton" rather than "file", since
5493 it's no longer just a file.
5494 * data/glr.c: Grant a special exception for C GLR parsers, that
5495 reads like the already-existing exception for C LALR(1) parsers.

5512 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
5513 We can revert this once things settle down.

5516 when %expect fails because there were no conflicts.

5756 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
5758 Undo the parts of the unlocked-I/O change that substituted
5759 putc or puts for printf. This might hurt performance a bit,
5760 but some people prefer the printf style.

5791 Use unlocked I/O for a minor performance improvement on hosts like
5792 GNU/Linux and Solaris that support unlocked I/O. The basic idea
5793 is to use the gnlib unlocked-io module, and to prefer putc and
5794 puts to printf when either will work (since the latter doesn't
5795 come in an unlocked flavor).
5796 * bootstrap (gnulib_modules): Add unlocked-io.

5863 to allow support for non-posix systems. This is a no-op function
5866 * lib/subpipe.h: New function end_of_output_subpipe() added
5867 to allow support for non-posix systems. This is a no-op function
5870 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
5871 handle the lack of pipe/fork functionality on non-posix systems.

5889 2005-10-02 Akim Demaille <akim@epita.fr>
5891 * data/location.cc: New, extract from...
5892 * data/lalr1.cc: here.
5893 (location.hh): Include it after the user prologue, in case the
5894 filename type is defined by the user.
5895 Forward declation location and position before the pre-prologue.
5896 (yyresult_): Rename as...
5897 (yyresult): this, it's a local variable, not an attribute.
5898 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
5900 2005-10-01 Akim Demaille <akim@epita.fr>
5902 * examples/extexi: Restore the #line generation.

5909 (parser::token): New, from the moved free definition of tokens.
5910 (parser::semantic_value): Now a full definition instead of an
5911 indirection to YYSTYPE.
5912 (b4_post_prologue): No longer included in the header file, but
5913 in the implementation file.
5914 * doc/bison.texi (C+ Language Interface): Update.
5915 * src/parse-gram.y: Support unary %define.
5916 * tests/actions.at: Define global_tokens_and_yystype for backward
5917 compatibility until we update the tests.
5918 * tests/calc.at: Idem.
5919 (first_line, first_column, last_line, last_column): Define for lalr1.cc
5920 to simplify the code.
5922 2005-09-29 Paul Eggert <eggert@cs.ucla.edu>
5924 Port to SunOS 4.1.4, which lacks strtoul and strerror.
5925 Ah, the good old days! Problem reported by Peter Klein.
5926 * bootstrap (gnulib_modules): Add strerror, strtoul.
5927 * lib/.cvsignore: Add strerror.c, strtol.c, strtoul.c
5928 * m4/.cvsignore: Add strerror.m4, strtol.m4, strtoul.m4.

5935 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
5936 parser members, replaced by...
5937 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
5939 (yysyntax_error_): Takes the state number as argument.
5940 (yyreduce_print_): Use the argument yyrule, not the former
5943 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
5945 * bootstrap (gnulib_modules): Add verify.

5954 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
5955 local variables whose names begin with 'yy'.
5956 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
5957 Trivial changes from Joel E. Denny.
5959 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
5961 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
5962 don't use alloca any more.
5964 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
5965 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
5966 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
5967 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
5968 to match yacc.c, to test more hosts.
5970 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
5972 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
5973 doesn't affect behavior.
5974 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
5976 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
5977 This works a bit better with glibc, if user code has already included
5979 * doc/bison.texinfo (Bison Parser): Document that users can't
5980 arbitrarily use malloc and free for other purposes. Document
5981 that <alloca.h> and <malloc.h> might be included.
5982 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
5983 user must declare alloca.

5992 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
5994 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
5995 (YYSTACK_ALLOC_MAXIMUM): Use it.
5996 (yysyntax_error): New function.
5997 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
5998 multiple syntax errors are reported, and alloca is being used.
5999 Instead, reallocate buffers twice as big each time, so that
6000 we waste at most half the allocated memory. Start with a small
6001 (128-byte) buffer that will suffice in most cases anyway.
6002 Use yysyntax_error to do most of the work.
6004 * doc/bison.texinfo (Error Reporting, Table of Symbols):
6005 yynerrs is the number of errors reported, not the number of
6008 * tests/glr-regression.at (Duplicated user destructor for lookahead):
6009 Mark it as expected to fail.
6010 Cast result of malloc; problem reported by twlevo@xs4all.nl.
6011 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
6012 Don't start user-code symbols with "yy", to avoid name space problems.
6014 2005-09-19 Akim Demaille <akim@epita.fr>
6016 Remove the traits, failed experiment.
6017 It never proved useful, and anyway because of the current
6018 definition, it was not possible to have several specialization of
6019 this traits, making it useless.
6020 * data/lalr1.cc (yy:traits): Remove.
6021 Inline its definitions in the parser class.
6023 2005-09-19 Akim Demaille <akim@epita.fr>

6046 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
6047 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
6048 is not defined. This is an awful hack, but it's enough for now.
6049 All callers changed.
6050 * tests/glr-regression-at (make_value): Args are const pointers now,
6051 to avoid GCC warning.
6052 (Duplicated user destructor for lookahead): New test. Currently
6053 skipped. It fails on my host but I'm not sure it'll always fail.
6055 2005-09-16 Akim Demaille <akim@epita.fr>
6057 * src/symtab.h (struct symbol): Declare the printer and destructor
6058 as const, to avoid accidental calls to free.
6059 (symbol_destructor_set, symbol_printer_set): Adjust.
6060 * src/symtab.c: Adjust.
6062 2005-09-16 Akim Demaille <akim@epita.fr>
6064 * data/c.m4 (b4_token_enums): New.
6065 (b4_token_defines): Rename as...
6066 (b4_token_enums_defines): this.
6067 (b4_token_defines): New, output only the #defines.
6068 * data/yacc.c, data/glr.c: Adjust.
6069 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
6070 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
6073 2005-09-16 Akim Demaille <akim@epita.fr>
6075 * data/lalr1.cc (yylex_): Remove, inline its code.
6076 (yyreport_syntax_error_): Remove, replaced by...
6077 (yysyntax_error_): this which returns a string and leaves to the
6078 caller the call to the users' error function.
6079 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
6080 Move from members of the parser object...
6081 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
6082 to local variables of the parse function.
6084 2005-09-16 Akim Demaille <akim@epita.fr>
6086 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
6087 since it's in Bison's name space.
6089 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
6091 * data/glr.c (yyresolveValue): Add default case to pacify
6092 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
6094 * NEWS: Document when yyparse started to return 2.
6095 * doc/bison.texinfo (Parser Function): Document when yyparse
6098 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
6099 (b4_filename_type): Renamed back from b4_file_name_type. All uses
6101 (class position): file_name -> filename (reverting). All uses changed.
6103 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
6105 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
6106 do anything if $@ exists. This reverts part of the 2005-07-07
6109 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
6111 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
6112 contains obsolete information and isn't worth distributing as a
6113 separate file anyway.
6114 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
6115 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
6116 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
6117 (yyparse): Abort if user code uses longjmp to throw an unexpected
6120 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
6122 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
6123 Suggested by twlevo@xs4all.nl.
6125 * data/glr.c (YYCHK1): Do not assume YYE is in range.
6126 This avoids a diagnostic from gcc -Wswitch-enum.
6127 Problem reported by twlevo@xs4all.nl.
6129 * doc/bison.texinfo: Don't use "filename", as per GNU coding
6130 standards. Use "file name" or "file" or "name", depending on
6132 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
6133 not to hack/foo.tab.c.
6134 (Calc++ Top Level): 2nd arg of main is not const.
6135 * data/glr.c: b4_filename -> b4_file_name.
6136 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

6153 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
6155 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
6158 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6160 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
6161 All uses changed. Invoke user destructor after an error during a
6162 split parse (trivial change from Joel E. Denny).
6164 * tests/glr-regression.at
6165 (User destructor after an error during a split parse): New test case.
6166 Problem reported by Joel E. Denny in:
6167 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
6169 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6171 * README-cvs: Give URLs for recommended tools.
6172 Mention Gzip version problem, and bootstrapping issues.
6173 Remove troubleshooting section, as it's somewhat obsolete.
6175 * bootstrap (no_cache): New var, to accommodate different wget
6176 variants. Use it instead of '-C off'. Problem reported by
6179 * data/glr.c (yydestroyStackItem): New function.
6180 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
6181 debugging information. Problem reported by Joel E. Denny.
6183 2005-08-25 Akim Demaille <akim@epita.fr>
6185 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
6187 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

6190 Don't invoke destructor on unresolved entries.
6191 * tests/glr-regression.at
6192 (User destructor for unresolved GLR semantic value): New test case.
6193 Problem reported by Joel E. Denny in:
6194 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
6196 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
6198 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
6200 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
6201 lib-prefix.m4, po.m4.
6203 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
6204 in yydestruct diagnostic, since it might not be an error.
6205 Problem reported by Joel Denny near end of
6206 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6207 * data/lalr1.cc (yyerturn): Likewise.
6208 * data/yacc.c (yyreturn): Likewise.
6209 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
6211 * src/files.c: Remove obsolete FIXME comment.
6213 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
6214 with the other templates, and to fix bogus run-on messages such
6215 as the one reported at the end of
6216 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6217 All callers changed to avoid the newline.
6218 (yyprocessOneStack): Output two lines rather than one, to accommodate
6219 the above change. This changes the debug output format slightly.
6221 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
6222 reported by Joel E. Denny in
6223 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
6225 * tests/glr-regression.at (Duplicate representation of merged trees):
6226 New test, from Joel E. Denny in:
6227 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
6228 * THANKS: Add Joel E. Denny.
6230 * configure.ac (AC_INIT): Bump to 2.0c.
6232 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
6234 * NEWS: Version 2.0b.
6236 * Makefile.am (SUBDIRS): Put examples before tests, so that
6237 "make check" doesn't finish with "All 1 tests passed".
6239 * tests/regression.at (Token definitions): Don't rely on
6240 AT_PARSER_CHECK for data that contains backslashes. It currently
6241 uses 'echo', and 'echo' isn't portable if its argument contains
6242 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
6243 that the byte '\0xff' is not printable in the C locale; it is,
6244 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
6245 not printable, so use '\0x81' to test.
6247 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
6248 version of GCC, since the macro is used with non-GCC compilers.
6250 Fix core dump reported by Pablo De Napoli in
6251 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
6252 * tests/regression.at (Invalid inputs with {}): New test.
6253 * src/parse-gram.y (token_name): Translate type before using
6256 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
6257 the user's name space. All uses changed to __attribute__
6259 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
6260 Add __attribute__ ((__noreturn__)).
6262 * etc/clcommit: Remove. We weren't using it, and it failed
6263 "make maintainer-distcheck".
6264 * Makefile.maint: Merge from coreutils.
6265 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
6266 (syntax-check-rules): Change list of rules as described below.
6267 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

6275 (makefile-check, po-check, author_mark_check):
6276 (makefile_path_separator_check, copyright-check):
6277 Use grep -n, to make it easier to find violations.
6278 Use CVS_LIST and CVS_LIST_EXCEPT.
6279 (header_regexp, h_re): Remove.
6281 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
6282 (my-distcheck): Use more-modern GCC flags.
6283 (signatures, %.asc): Remove.
6284 (rel-files, announcement): Remove signatures.
6285 Restore old updating code, even though we don't use it, so
6286 that we're the same as coreutils.
6287 (alpha, beta, major): Depend on news-date-check.
6288 Make the upload commands.
6290 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

6297 * tests/sets.at: Likewise.
6299 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
6300 we comment out the Autoconf version number.
6301 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
6302 it's error-prone and "make maintainer-distcheck" rejects it.
6304 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
6305 Indent calls to "error" to pacify "make maintainer-distcheck",
6306 when the calls are not intended to be translated.
6307 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
6309 * src/Makefile.am (DEFS): Use +=, to pacify
6310 "make maintainer-distcheck".
6311 (bison_SOURCES): Add scan-skel.h.
6312 (sc_tight_scope): New rule, from coreutils.
6314 * src/files.c (src_extension, header_extension):
6315 Now static, not extern.
6316 * src/getargs.c (short_options): Likewise.
6317 * src/muscle_tab.c (muscle_table): Likewise.
6318 * src/parse-gram.y (current_class, current_type, current_prec):
6320 * src/reader.c (grammar_end, previous_rule_end): Likewise.
6321 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
6322 * src/main.c (main): Cast bindtextdomain and textdomain calls to
6323 void, to avoid warning when NLS is disabled.
6324 * src/output.c: Include scan-skel.h.
6325 (scan_skel): Remove decl, since scan-skel.h does this.
6327 Indent calls to "error" to pacify "make maintainer-distcheck".
6328 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
6329 * src/reader.h (gram_end, gram_lineno): New decls to pacify
6330 "make maintainer-distcheck".
6331 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
6332 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
6333 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
6334 (skel_lex_destroy, scan_skel): Move these decls to...
6335 * src/scan-skel.h: New file.
6336 * src/uniqstr.c (uniqstr_assert):
6337 Indent calls to "error" to pacify "make maintainer-distcheck".
6339 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
6342 * tests/torture.at: Revamp to avoid misuse of atoi that
6343 "make maintainer-distcheck" complained about.
6345 * examples/extexi (message): Don't print a message more than once,
6346 and omit line-number decoration that makes Emacs compile think
6347 that informative messages are worth worrying about.
6349 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
6351 * configure.ac: Update version number.
6353 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
6355 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
6356 autogenerated by the maintainer.
6357 * examples/calc++/.cvsignore: Add *.yy.
6359 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
6360 * lib/bitset_stats.c (bitset_stats_init): Likewise.
6361 * lib/bitsetv.c (bitsetv_alloc): Likewise.
6363 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
6365 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
6366 from maintainer-distcheck about casting the argument of 'free'.
6368 * NEWS: Mention recent yytname changes.
6369 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
6371 * bootstrap: For translations that have not yet been upgraded to
6372 the new runtime-po domain, prime the pump by extracting the
6373 relevant strings from the obsolete translations. This code can be
6374 removed once the bison-runtime domain has been translated by each
6377 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
6378 now that token names are already quoted.
6380 Fix problem reported by Anthony Heading.
6381 * data/glr.c (YYTOKEN_TABLE): New macro.
6382 (yytname): Define if YYTOKEN_TABLE.
6383 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
6384 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
6385 (YYERROR_VERBOSE): Define the same way the other skeletons do.
6386 * src/output.c (prepare_symbols): Output token_table_flag.
6388 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
6390 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
6391 again if the first call fails.
6393 * data/glr.c (yytnamerr): New function.
6394 (yyreportSyntaxError): Use it to dequote most string literals.
6395 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
6396 with other skeletons. All uses changed.
6397 (yytnameerr_): New function.
6398 (yyreport_syntax_error): Use it to dequote most string literals.
6399 * data/yacc.c (yytnamerr): New function.
6400 (yyerrlab): Use it to decode most string literals.
6401 * doc/bison.texinfo (Decl Summary, Calling Convention):
6402 Clarify quoting convention of yytname.
6403 * src/output.c (prepare_symbols): Quote all names. This undoes
6404 the 2005-04-17 change, which is now accomplished (mostly) via
6405 changes in the parsers as described above.
6406 * tests/regression.at (Token definitions, Web2c Actions):
6407 Undo most 2005-04-17 change here, too.
6409 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
6411 Fix more problems reported by twlevo@xs4all.nl.
6412 * tests/cxx-type.at: Don't pipe output of ./types through sed to
6413 remove trailing spaces. This loses the exit status of ./types,
6414 and isn't needed since ./types shouldn't be emitting trailing
6416 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
6417 as the stack isn't valid in that case.
6419 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6420 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6421 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6422 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
6424 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
6425 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
6426 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
6429 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
6430 overly-picky compilers that reject 'char *foo = "bar";'.
6432 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
6433 to FILE * parameter, not to stderr. This fixes a typo introduced
6434 in the 2005-07-12 change.
6436 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
6437 warnings from GCC 4.
6439 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
6440 (yyglrShiftDefer, yysplitStack):
6441 Remove unused parameters b4_pure_formals. All uses changed.
6442 (yyglrShift): Remove unused parameters b4_user_formals.
6444 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
6446 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
6448 Destructor cleanups and regularization among the three skeletons.
6449 * NEWS: Document the behavior changes.
6450 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
6451 stack before failing, as the cleanup code will do it for us now.
6452 * data/lalr1.cc (yyerrlab): Likewise.
6453 * data/glr.c (yyparse): Pop everything off the stack before
6454 freeing it, so that destructors get called properly.
6455 * data/lalr1.cc (yyreturn): Likewise.
6456 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
6457 This is more consistent.
6458 * doc/bison.texinfo (Destructor Decl): Mention more reasons
6459 why destructors might be called. 1.875 -> 2.1.
6460 (Destructor Decl, Decl Summary, Table of Symbols):
6461 Some English-language cleanups for %destructor.
6462 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6463 Add output line for destructor of start symbol.
6464 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
6465 because of that same extra output line.
6467 * NEWS: Document minor wording changes in diagnostics of
6468 Bison-generated parsers.
6469 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
6470 Remove unused formals. All uses changed.
6471 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
6472 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
6473 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
6474 Rename yyoverflowab to yyexhaustedlab.
6475 When memory exhaustion occurs during syntax-error reporting,
6476 report it separately rather than in a single diagnostic; this
6478 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
6479 (Memory Exhausted): Renamed from Parser Stack Overflow.
6480 Revamp wording slightly to prefer "memory exhaustion".
6481 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
6483 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
6485 Add i18n support to the GLR skeleton. Partially fix the C++
6486 skeleton; a C++ expert needs to finish this. Remove debugging
6487 msgids; there's little point to having them translated, since they
6488 can be understood only by someone who can read the
6489 (English-language) source code.
6491 Generate runtime-po/bison-runtime.pot automatically, so that we
6492 don't have to worry about garbage getting in that file. We'll
6493 make sure after the next official release that old msgids don't
6495 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
6497 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
6499 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
6500 Fix typos in explanations of the runtime file.
6501 * bootstrap: Change gettext keyword from YYI18N to YY_.
6502 Use standard Makefile.in.in in runtime-po, since we'll arrange
6503 for backward-compatible bison-runtime.po files in a different way.
6504 * data/glr.c (YY_): New macro, from yacc.c.
6505 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
6506 Translate messages intended for users.
6507 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
6508 the wording in the other skeletons. We don't know that the memory
6510 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
6511 Use same method that yacc.c uses.
6512 Don't translate debugging messages.
6513 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
6514 it doesn't work (yet), and requires C++ expertise to fix.
6515 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
6516 Move defn to a more logical place, to be consistent with other
6518 Don't translate debugging messages.
6519 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
6520 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
6521 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
6522 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
6524 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
6525 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
6527 * tests/glr-regression.at (Badly Collapsed GLR States):
6529 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6530 yylex should return 0 at EOF rather than aborting.
6532 Improve tests for stack overflow in GLR parser.
6533 Problem reported by twlevo@xs4all.nl.
6534 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
6536 (yyStackOverflow): Just longjmp, but with value 2 so that caller
6537 can handle the problem.
6538 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
6539 (yyparse): New local variable yyresult to record the result.
6540 Use result of setjmp to set it, rather than storing itinto
6542 (yyDone): Remove label.
6543 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
6544 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
6545 if YYABORT is used).
6546 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
6547 yyparse status; put status > 1 into diagnostic.
6548 Check that status==2 works.
6549 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
6550 Use exit status 3 for failure to open (which shouldn't happen).
6552 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
6554 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
6555 1 on syntax error; just let yyparse do its thing.
6556 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
6557 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
6558 (Exploding the Stack Size with Alloca):
6559 (Exploding the Stack Size with Malloc):
6560 Expect exit status 2, not 1, since the parser is supposed to blow
6561 its stack. Problem reported by twlevo@xs4all.nl.
6563 * data/glr.c (yyparse): Don't assume that the initial calls
6564 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
6565 Print a stack-overflow message and fail instead.
6566 Initialize the line-number information before creating the stack,
6567 so that the stack-overflow message can report line zero safely.
6569 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
6571 Fix problems reported by twlevo@xs4all.nl.
6572 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
6573 (yyuserMerge): Provide a default case if b4_mergers is empty.
6574 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
6575 * tests/glr-regression.at
6576 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6577 Add casts to pacify C++ compilers.
6578 * tests/glr-regression.at (Improper merging of GLR delayed action
6579 sets): Declare yylex before using it.
6580 * tests/Makefile.am (maintainer-check-g++): Fix a stray
6581 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
6582 test for valgrind; valgrind is independent of g++.
6583 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
6584 for compatibility with POSIX 1003.1-2001 (if running coreutils).
6585 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
6586 Use a destructor, so that we can expand the stack. Change
6587 YYSTYPE to char * so that we can free it. Cast result of malloc.
6589 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
6591 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
6592 a valgrind failure. Problem reported by twlevo@xs4all.nl.
6594 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
6596 * PACKAGING: New file, suggested by Bruno Haible and taken from
6597 similar wording in gettext's PACKAGING file.
6598 * NEWS: Mention PACKAGING.
6599 * Makefile.am (EXTRA_DIST): Add PACKAGING.
6601 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
6603 * NEWS: Document recent i18n improvements.
6604 * bootstrap: Get runtime translations into runtime-po.
6605 Create runtime-po files automatically, if possible.
6606 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
6607 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
6608 does not infringe on the user's name space.
6609 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
6610 * doc/bison.texinfo (Internationalization): Revamp the English
6611 and Texinfo syntax a bit, to try to make it clearer.
6612 (Bison Options, Option Cross Key): Mention --print-localedir.
6613 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
6614 YYENABLE_NLS. Quote a bit more.
6615 * runtime-po/.cvsignore: New file.
6616 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
6617 * runtime-po/Rules-quot: Remove; now created by bootstrap.
6618 * runtime-po/quot.sed: Likewise.
6619 * runtime-po/boldquot.sed: Likewise.
6620 * runtime-po/en@quot.header: Likewise.
6621 * runtime-po/en@boldquot.header: Likewise.
6622 * runtime-po/insert-header.sin: Likewise.
6623 * runtime-po/remove-potcdate.sin: Likewise.
6624 * runtime-po/Makevars: Likewise.
6625 * runtime-po/LINGUAS: Likewise.
6626 * runtime-po/de.po: Likewise; we will rely on the translation project
6627 to maintain this, so "bootstrap" should get it.
6628 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
6630 * src/main.c (main): Bind the bison-runtime domain, too.
6632 2005-07-12 Bruno Haible <bruno@clisp.org>
6634 * data/yacc.c: Include <libintl.h> when NLS is enabled.
6635 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
6636 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
6637 * runtime-po: New directory.
6638 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
6639 $(DOMAIN).pot-update rule, so that old messages are never dropped.
6640 * runtime-po/Rules-quot: New file, copied from po/.
6641 * runtime-po/quot.sed: Likewise.
6642 * runtime-po/boldquot.sed: Likewise.
6643 * runtime-po/en@quot.header: Likewise.
6644 * runtime-po/en@boldquot.header: Likewise.
6645 * runtime-po/insert-header.sin: Likewise.
6646 * runtime-po/remove-potcdate.sin: Likewise.
6647 * runtime-po/Makevars: New file.
6648 * runtime-po/POTFILES.in: New file.
6649 * runtime-po/LINGUAS: New file.
6650 * runtime-po/bison-runtime.pot: New file.
6651 * runtime-po/de.po: New file.
6652 * m4/bison.m4: New file.
6653 * Makefile.am (SUBDIRS): Add runtime-po.
6654 (aclocaldir, aclocal_DATA): New variables.
6655 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
6657 * src/getargs.c (usage): Document --print-localedir option.
6658 (PRINT_LOCALEDIR_OPTION): New enum item.
6659 (long_options): Add --print-localedir option.
6660 (getargs): Handle --print-localedir option.
6661 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
6662 (Internationalization): New section.
6664 2005-07-12 Akim Demaille <akim@epita.fr>
6666 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
6667 for consistency with the rest of the code.
6668 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
6671 2005-07-12 Akim Demaille <akim@epita.fr>
6673 * src/parse-gram.y: Use %printer instead of YYPRINT.
6675 2005-07-12 Akim Demaille <akim@epita.fr>
6677 * src/symtab.h, src/symtab.c (symbol_print): New.
6678 * src/symlist.h, src/symlist.c (symbol_list_print): New.
6679 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
6681 2005-07-12 Akim Demaille <akim@epita.fr>
6683 * data/glr.c (b4_syncline): Fix (swap) the definitions of
6684 b4_at_dollar and b4_dollar_dollar.
6686 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
6688 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
6689 and Pennello's paper.
6691 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
6693 * data/yacc.c (yyparse): Undo previous patch. Instead,
6694 set yylsp[0] and yyvsp[0] only if the initial action
6695 sets yylloc and yylval, respectively.
6697 * data/yacc.c (yyparse): In the initial action, set
6698 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
6699 This avoids the use of undefined variables if the initial
6700 action does not set yylloc and/or yylval.
6702 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6704 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
6705 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
6706 Remove from CVS. These files are automatically generated.
6707 * examples/extexi: Clarify that this file is now part of Bison,
6708 not GNU M4, and that it works with any POSIX-compatible Awk.
6709 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
6710 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
6711 so that we also get calc++-parser.yy. Geneate it.
6712 Use $(AWK), not gawk, since any conforming Awk will do.
6713 Put comment before action, since older 'make' can't handle comment
6715 $(BUILT_SOURCES): List all built sources, not just some of them.
6716 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
6717 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
6718 $($(calc_sources_generated)): Remove unnecessary test for existence
6719 of target. (This had a shell syntax error anyway; a stray "x".)
6720 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
6722 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
6724 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
6725 implied by the other modules.
6727 2005-07-06 Akim Demaille <akim@epita.fr>
6729 Bind examples/calc++ to the package.
6730 * examples/calc++/Makefile: Remove, replaced by...
6731 * examples/calc++/Makefile.am: ... this new file.
6732 * examples/calc++/test: Remove input.
6733 * examples/calc++/compile: Remove.
6734 * examples/Makefile.am: New.
6735 * configure.ac, Makefile.am: Adjust.
6736 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
6738 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
6740 * data/glr.c (yyFail): Drastically simplify; since the format argument
6741 never had any % directives, we can simply pass it to yyerror.
6742 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
6743 be modified later, as that is the usual style in glr.c.
6744 Problems reported by Paul Hilfinger.
6746 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
6747 and size overflow errors.
6748 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
6749 in case the user prolog sets feature-test macros like _GNU_SOURCE.
6750 (YYSIZEMAX): New macro.
6751 (yystpcpy): New function, taken from yacc.c.
6752 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
6753 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
6754 so that we don't have to maintain their signatures.
6755 (yyFail): Check for buffer overflow, by using vsnprintf rather
6756 than vsprintf. Allocate a bigger buffer if possible.
6757 Report an error if buffer allocation fails.
6758 (yyStackOverflow): New function.
6759 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
6760 the initialization was successful. It might fail if storage was
6762 (yyexpandGLRStack): Add more checks for storage allocation failure.
6763 Use yyStackOverflow to report failures.
6764 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
6765 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
6766 Don't assume stack number fits in int.
6767 (yysplitStack): Check for storage allocation failure.
6768 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
6769 can print diagnostics on storage allocation failure. All callers

6812 which stems from the 2005-05-27 patch.
6814 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
6816 * data/glr.c: Modify treatment of unused parameters to permit use

6831 Fix infringement on user name space reported by Bruno Haible.
6832 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
6833 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
6834 the user's name space.
6835 (alloca): Include <stdlib.h> to get it, if it's not built in.
6836 (YYMALLOC, YYFREE): Define only if needed.
6837 (malloc, free): Declare, but only if needed, as this infringes on
6838 the user name space.
6840 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
6842 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.

6865 * NEWS: Version 2.0a.
6867 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
6868 the previous change.
6870 Various maintainer cleanups.
6871 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
6872 conftest*, for benefit of CVS commands run at the same time as
6873 "configure". Add build-aux, since "bootstrap" now creates it and
6875 * Makefile.cfg (move_if_change): Remove.
6876 * Makefile.maint: Remove the update stuff; we now use "bootstrap".

6887 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
6888 ylwrap. These files now go into build-aux.

6898 (create_subpipe): Make sure all the newly-created
6899 file descriptors are > 2, so that diagnostics don't
6900 get sent down them (which might cause Bison to hang, in theory).
6901 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
6902 * src/files.c (xfopen): Use fopen_safer, not fopen.

6916 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
6917 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,

6980 Problem reported by Ralf Menzel.
6982 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6984 * tests/actions.at: Test that stack overflow invokes destructors.
6985 From Marcus Holland-Moritz.
6986 * data/yacc.c (yyerrlab): Move the code that destroys the stack
6988 (yyreturn): to here. That way, destructors are called properly
6989 even if the stack overflows, or the user calls YYACCEPT or
6990 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
6991 (yyoverflowlab): Destroy the lookahead.
6993 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
6995 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
6997 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
6999 * NEWS: Bison-generated C parsers no longer quote literal strings
7000 associated with tokens.
7001 * src/output.c (prepare_symbols): Don't escape strings,
7002 since users don't want to see C escapes.

7005 * tests/input.at (Torturing the Scanner): Likewise.
7006 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
7008 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
7010 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
7011 the data size is known to be too small and we can't increase it.
7012 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
7014 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
7016 * src/parse-gram.y: Include quotearg.h.
7017 (string_as_id): Quote $1 before using it as a key, since the
7018 lexer no longer quotes it for us.
7019 (string_content): Don't strip quotes, since lexer no longer
7021 * src/scan-gram.l: Include quotearg.h.
7023 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
7024 a key, since the rest of the lexer doesn't quote it.

7026 * tests/regression.at (Token definitions): Check for backslashes
7029 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
7030 (YYSIZE_T): Define to unsigned long int when using an older compiler.
7031 (yyparse): Revamp code to generate long syntax error message, to
7032 make it easier to translate, and to avoid problems with arithmetic
7033 overflow. Change "virtual memory" to "memory" in diagnostic, since
7034 we don't know whether the memory is virtual.
7036 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7038 * NEWS: Bison-generated C parsers now use the _ macro to
7040 * data/yacc.c (_) [!defined _]: New macro.
7041 All English strings wrapped inside this macro.
7042 * doc/bison.texinfo (Bison Parser): Document _.
7043 * po/POTFILES.in: Include src/parse-gram.c, since it now
7044 includes translateable strings that parse-gram.y doesn't.
7046 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
7048 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
7049 reverting the 2004-10-11 change to this function.
7050 (symbol_check_alias_consistency): Don't call symbol_type_set
7051 if the type name is already correct.
7052 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
7054 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
7056 * tests/regression.at (Token definitions): Don't use a token named
7057 c, as that generates a "#define c ..." that runs afoul of buggy
7058 stdlib.h that uses the identifier c as a member of struct
7059 drand48_data. Problem reported by Horst Wente.
7061 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
7063 * bootstrap: Change translation URL from
7064 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
7065 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
7066 redirection glitches. Problem reported by twlevo@xs4all.nl.
7068 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
7070 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
7071 after operands; POSIX says this isn't portable for the c99 command.
7073 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
7075 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
7076 immediately if a data overrun has occurred; this may help us track
7077 down what may be a spurious failure on MacOS.
7079 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
7081 Respond to problems reported by twlevo@xs4all.nl.

7094 "#if 0", since it's not currently used. Problem reported by
7097 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
7099 * src/output.c (escaped_output): Renamed from
7100 escaped_file_name_output, since we now use it for symbol tags as
7101 well. All uses changed.
7102 (symbol_destructors_output, symbol_printers_output):
7103 Escape symbol tags too.
7104 Problem reported by Matyas Forstner in
7105 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
7107 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
7109 * src/output.c (user_actions_output, token_definitions_output,
7110 symbol_destructors_output, symbol_printers_output): Likewise.
7111 * src/reader.c (prologue_augment): Likewise.
7112 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
7114 * src/vcg.c (output_edge): Don't quote linestyle arg.
7115 Problem reported by twlevo@xs4all.nl.
7117 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
7119 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
7120 example, reported by Derek M Jones. Also, make the example even
7121 more outrageous, to better illustrate how bad the problem is.
7123 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
7125 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
7126 putsym. Typo reported by Sebastian Piping.
7128 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7130 * doc/bison.texinfo (Language and Grammar): some -> same
7131 (Epilogue): int he -> in the
7132 Typos reported by Sebastian Piping via Justin Pence.
7134 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7136 * tests/glr-regression.at (Improper handling of embedded actions
7137 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
7138 embedded actions and $-N in GLR parsers", work around an Autoconf bug
7139 with dollar signs in test names.
7140 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
7141 for a similar reason.
7143 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7145 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
7146 wants to redefine G_VIEW.

7169 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
7170 keyword; it's not needed with modern compilers, and it doesn't
7171 affect correctness with older compilers. Suggested by
7174 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
7176 * data/glr.c (yyuserAction): Add "default: break;" case to pacify

7188 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
7189 for the benefit of slower hosts. Problem reported by
7192 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
7194 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
7195 being defined and not used.
7196 * data/lalr1.cc (yyparse): Likewise.

7227 1.875, so that related items are grouped together.
7228 * configure.ac (AC_INIT): Bump version to 2.0.
7229 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
7231 * tests/torture.at (Exploding the Stack Size with Alloca): Set
7232 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
7233 otherwise, we're not testing alloca. Unfortunately there's no
7234 simple way to consult HAVE_ALLOCA here.
7236 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
7239 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
7240 hand. This avoids a warning about comparing int to size_t when
7241 GCC warnings are enabled.
7243 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
7245 * NEWS: Bison-generated parsers no longer default to using the
7246 alloca function (when available) to extend the parser stack, due
7247 to widespread problems in unchecked stack-overflow detection.
7248 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
7249 responsibility to set it to a positive value. This lets the user
7250 specify a value that is not a preprocessor constant.
7251 * data/yacc.c (YYMAXDEPTH): Likewise.
7252 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
7253 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
7254 to be a compile-time constant. However, explain the constraints on it.
7255 Also, explain the constraints on YYINITDEPTH.
7256 (Table of Symbols): Explain that alloca is no longer the default.
7257 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
7260 * doc/bison.texinfo (Location Default Action): Mention that n must
7261 be zero when k is zero. Suggested by Frank Heckenbach.
7263 2004-12-22 Akim Demaille <akim@epita.fr>
7265 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
7266 (parser::state_type, parser::semantic_type, parser::location_type):
7267 Private, not public.
7268 (parser::parse): Return ints, not bool.
7269 Returning a bool introduces a problem: 0 corresponds to false, and
7270 it seems weird to return false on success. Returning true changes
7271 the conventions for yyparse.
7272 Alternatively we could return void and send an exception.
7273 There is no clear consensus (yet?).
7274 (state_stack, semantic_stack, location_stack): Rename as...
7275 (state_stack_type, semantic_stack_type, location_stack_type): these.
7276 Private, not public.
7277 * tests/c++.at: New.
7278 * tests/testsuite.at, tests/Makefile.am: Adjust.
7280 2004-12-21 Akim Demaille <akim@epita.fr>
7282 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
7284 2004-12-21 Akim Demaille <akim@epita.fr>
7286 Don't impose std::string for filenames.
7288 * data/lalr1.cc (b4_filename_type): New.
7289 (position::filename): Use it.
7290 (parser.hh): Move the inclusion of stack.hh and location.hh below
7291 the user code, so that needed headers for the filename type can be
7293 Forward declare them before the user code.
7294 * tests/Makefile.am (check-local, installcheck-local): Pass
7295 TESTSUITEFLAGS to the TESTSUITE.
7297 2004-12-20 Akim Demaille <akim@epita.fr>
7299 Use more STL like names: my_class instead of MyClass.
7301 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
7302 (SemanticStack, SemanticType, StateStack, StateType)
7303 (TokenNumberType, Stack, Slice, Traits, Parser::location)
7304 (Parser::value): Rename as...
7305 (location_stack, location_type, rhs_number_type, semantic_stack)
7306 (semantic_type, state_stack, state_type, token_number_type, stack)
7307 (slice, traits, parser::yylloc, parser::yylval): these.
7309 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
7311 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
7313 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
7314 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
7316 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
7318 Remove uses of 'short int' and 'unsigned short int'. This raises
7319 some arbitrary limits. It uses more memory but nowadays that's
7320 not much of an issue.
7322 This change does not affect the generated parsers; that's a different
7323 task, as some users will want to conserve memory there.
7325 Ideally we should use size_t to represent all object counts, and
7326 something like ptrdiff_t to represent signed differences of object
7327 counts; but that will require more code-cleanup than I have the
7328 time to do right now.
7330 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
7331 Use size_t, not int or short int, to count objects.
7332 * src/closure.c (nritemset, closure): Likewise.
7333 * src/closure.h (nritemset, closure): Likewise.

7344 errs, reductions): Likewise.
7345 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
7347 * src/tables.c (vector_number, tally, action_number,
7348 ACTION_NUMBER_MINIMUM): Likewise.
7349 * src/output.c (muscle_insert_short_int_table): Remove.
7351 2004-12-17 Akim Demaille <akim@epita.fr>
7353 * data/lalr1.cc: Extensive Doxygenation.
7354 (error_): Rename as...
7355 (error): this, since it is visible to the user.
7357 (Parser::message): Now an automatic variable from...
7358 (Parser::yyreport_syntax_error_): here.
7359 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
7361 * tests/input.at: Escape $.
7363 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
7365 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
7366 Parenthesize rhs to avoid obscure problems with mistakes like
7367 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
7368 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
7369 b4_rhs_location): Likewise.
7370 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
7371 b4_rhs_location): Likewise.
7373 2004-12-16 Akim Demaille <akim@epita.fr>
7375 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
7376 yacc.c: be sure to stay within yycheck_.
7377 * tests/actions.at: Re-enable C++ tests.
7379 2004-12-16 Akim Demaille <akim@epita.fr>
7381 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
7384 2004-12-16 Akim Demaille <akim@epita.fr>
7386 Use #define to handle the %name-prefix.
7388 * data/glr.c, data/yacc.c: Comment changes.
7389 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
7390 so that one can refer to yylex in the parser file, and have it
7391 renamed, as is the case with other skeletons.
7393 2004-12-16 Akim Demaille <akim@epita.fr>
7395 Move lalr1.cc internals into yy*.

7415 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
7417 Fix some problems reported by twlevo at xs4all.
7418 * src/symtab.c (symbol_new): Report an error if the input grammar
7419 contains too many symbols. This is better than calling abort() later.
7420 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
7421 (struct node, struct graph):
7422 Rename member expand to stretch. All uses changed.
7423 (struct graph): Remove member layoutalgorithm. All uses removed.
7424 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
7425 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.

7429 2004-12-15 Akim Demaille <akim@epita.fr>
7431 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
7432 Add more Doxygen comments.
7433 (symprint_, stack_print_, reduce_print_, destruct_, pop)
7434 (report_syntax_error_, translate_): Rename as...
7435 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
7436 (yypop_, yyreport_syntax_error_, yytranslate_): this.
7438 2004-12-15 Akim Demaille <akim@epita.fr>
7440 * data/lalr1.cc (lex_): Rename as...
7442 Move the trace here.
7443 Take the %name-prefix into account.
7444 Reported by Alexandre Duret-Lutz.
7446 2004-12-15 Akim Demaille <akim@epita.fr>
7448 Simplify the C++ parser constructor.
7450 * data/lalr1.cc (debug_): Rename as...
7451 (yydebug_): so that the parser's internals are always in the yy*
7454 (b4_parse_param_decl): Remove the leading comma as it is now only
7455 called as unique argument list.
7456 (Parser::Parser): Remove the constructor accepting a location and
7457 an initial debugging level.
7458 Remove from the other ctor the argument for the debugging level.
7459 (debug_level_type, debug_level, set_debug_level): New.
7461 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
7464 2004-12-15 Akim Demaille <akim@epita.fr>
7466 Remove b4_root related material: failure experiment
7467 (which goal was to allow to derive from a class).
7469 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
7470 definitions and uses.
7472 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
7474 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
7475 not 2, since it's not portable to subtract 1 from the start of an
7476 array. The new item 0 is never set or used. All uses changed.
7478 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
7479 the default definition of YYLLOC_DEFAULT. Problem reported
7480 by Frank Heckenbach.
7482 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
7484 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
7485 the normal case and one for the error case. Just use the
7486 first one uniformly. Problem reported by Frank Heckenbach.
7487 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
7488 use exactly the same macro in both places.
7489 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
7490 so that the normal-case YYRHSLOC works for the error case too.
7492 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
7493 (YYLLOC_DEFAULT): Use the same macro as glr.c.
7494 * doc/bison.texinfo (Location Default Action): Don't claim that
7495 we have an array of locations. Use the same macro for both glr
7496 and lalr parsers. Mention YYRHSLOC. Mention what happens when
7499 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
7501 * HACKING: Update email addresses to send announcements to.
7503 * configure.ac (AC_INIT): Bump version to 1.875f.

7508 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
7510 * src/scan-skel.l: Include "complain.h", for "fatal".
7512 * src/relation.h (relation_print, relation_digraph):
7513 Relation sizes are of type relation_node, not size_t (this is
7514 merely a doc fix, since the two types are equivalent).
7515 (relation_transpose): Relation sizes are of type relation_node,
7517 * src/relation.c: Likewise.
7518 (top, infinity): Now of type relation_node, not int.
7519 (traverse, relation_transpose): Use relation_node, not int.
7521 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
7522 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
7523 (yyparse): Remove unused local introduced in 2004-10-25 patch.
7525 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
7526 specifying whether the test should be skipped. Use it tp
7527 specify that the [%defines %skeleton "lalr1.cc"] tests currently
7528 fail on some hosts, and should be skipped.
7530 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
7532 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
7533 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
7534 unless otherwise specified below.
7536 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
7537 to allocate kernel_base, kernel_items, kernel_size, since
7538 they needn't be initialized to 0.
7539 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
7540 * src/closure.c (new_closure): Likewise, for itemset.

7556 (goto_actions): Likewise for state_count.
7557 (pack_table): Likewise for base, pos, check.
7558 (tables_generate): Likewise for width.
7560 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
7561 for initial core. Just have a separate core, so we needn't worry
7562 about whether kernel_size and kernel_base are initialized.
7564 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
7565 kernel_size, kernel_items): Remove unnecessary initialization.

7570 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
7571 conflrow, conflict_table, conflict_list, table, check):
7574 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
7575 This is because all callers pass unsigned int.
7576 * src/closure.h (new_closure): Likewise.
7578 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
7579 (build_relations): Initialize includes[i] in all cases.
7580 * src/reader.c (packgram): Always initialize rules[ruleno].prec
7581 and rules[ruleno].precsym. Initialize members in order.
7582 * src/relation.c (relation_transpose): Always initialize new_R[i]
7584 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
7586 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
7587 conflict_list[0] was always 0, but now it isn't initialized.
7589 * src/table.c (table_grow): When conflict_table grew, the grown
7590 area wasn't cleared. Fix this.
7592 * lib/.cvsignore: Add strdup.c, strdup.h.
7593 * m4/.cvsignore: Add strdup.m4.
7595 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
7597 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
7598 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
7599 GOTO_NUMBER_MAXIMUM, since we occasionally compute
7600 ngotos + 1 without checking for overflow.
7601 (build_relations): Use END_NODE, not -1, to denote end of edges.
7602 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
7603 build_relations): Use goto_number, not int, for goto numbers.

7606 2004-11-23 Akim Demaille <akim@epita.fr>
7608 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
7609 of #defining from yystype.
7610 Don't typedef yystype, C++ does not need it.
7611 This lets it possible to forward declare it as union.
7613 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
7615 * bootstrap (gnulib_modules): Add extensions.
7616 Problem reported by Jim Meyering.

7633 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
7636 Use it instead of cdebug_.
7637 (Parser::debug_stream, Parser::set_debug_stream): New.
7638 (Parser::symprint_): Define cdebug_ for temporary backward

7653 Problem reported by Frank Heckenbach.
7655 2004-10-25 Akim Demaille <akim@epita.fr>
7657 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
7658 Introduce another definition to address simple location arrays.
7659 (yyGLRStack): New member: yyerror_range.
7660 (yyrecoverSyntaxError, yyparse): Update it.
7661 (yyrecoverSyntaxError): Use it when shifting the error token to
7662 have an accurate range, equivalent to the one computed by both
7663 yacc.c and lalr1.cc.
7664 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
7665 that column numbers start at column 0, as per GNU Coding
7666 Standards, the others tests, and the doc.
7667 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
7668 Adjust to the above change (first column is 0).
7669 And adjust the location of the "<error>", now covering the whole
7672 2004-10-22 Akim Demaille <akim@epita.fr>
7673 and Paul Eggert <eggert@cs.ucla.edu>
7675 Remove some arbitrary limits on goto numbers and relations.
7676 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
7677 initial values, since they're never used.
7678 (set_goto_map): ngotos is now unsigned, so test for overflow
7679 by seeing whether it wraps around to zero.
7680 * src/lalr.h (goto_number): Now size_t, not short int.
7681 (GOTO_NUMBER_MAXIMUM): Remove.
7682 * src/relation.c (relation_print, traverse, relation_transpose):
7683 Check for END_NODE rather than looking at sign.
7684 * src/relation.h (END_NODE): New macro.
7685 (relation_node): Now size_t, not short int.
7687 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
7689 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
7690 keyword, not an identifier. Problem reported by Baron Schwartz in
7691 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
7693 2004-10-11 Akim Demaille <akim@epita.fr>
7695 * src/symtab.c (symbol_check_alias_consistency): Also check
7696 type names, destructors, and printers.
7697 Reported by Alexandre Duret-Lutz.
7698 Recode the handling of associativity and precedence in terms
7699 of symbol_precedence_set.
7700 Accept no redeclaration at all, not even equal to the previous
7702 (redeclaration): New.
7703 Use it to factor redeclaration complaints.
7704 (symbol_make_alias): Don't set the type of the alias, let
7705 symbol_check_alias_consistency do it as for other features.
7706 * src/symtab.h (symbol): Add new member prec_location, and
7708 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
7709 * tests/input.at (Incompatible Aliases): New.
7711 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
7713 .cvsignore fixes to accommodate gnulib changes,
7714 and the practice of naming build directories "_build".
7715 * .cvsignore: Add "_*". Sort.
7716 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
7717 * m4/.cvsignore: Add "*_gl.m4".
7719 2004-10-06 Akim Demaille <akim@epita.fr>
7721 * src/parse-gram.y (add_param): Fix the truncation of trailing
7724 2004-10-05 Akim Demaille <akim@epita.fr>
7726 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
7727 whether the reducion was empty or not. This leaves room to
7728 improve the use of YYLLOC_DEFAULT in such a case.
7729 lalr1.cc is still experimental, so changing this is acceptable.
7730 And finally, there are probably not many users who changed the
7731 handling of locations in GLR, so changing is admissible too.
7733 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
7734 empty reduction, set @$ to an empty location ending the previously
7736 Adjust uses to make sure the code is triggered on empty
7738 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
7739 expected output: empty reductions have empty locations.
7741 2004-09-29 Akim Demaille <akim@epita.fr>
7743 * data/lalr1.cc: Move towards a more standard C++ coding style
7744 for templates: Class < T > -> Class<T>.
7746 2004-09-29 Akim Demaille <akim@epita.fr>
7748 * data/lalr1.cc: Reinstall the former ctor, for sake of
7749 compatibility, but warn it will be removed.
7750 Move towards a more standard C++ coding style (i.e., type *var ->
7753 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
7755 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
7756 since it's less likely to work if NULs are involved in the future.
7758 2004-09-27 Akim Demaille <akim@epita.fr>
7760 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
7762 2004-09-27 Akim Demaille <akim@epita.fr>
7764 * data/lalr1.cc (b4_parse_param_decl_1): New.
7765 (b4_parse_param_decl): Use it to have different names between attribute
7767 (b4_cc_constructor_call): Likewise.
7769 2004-09-24 Akim Demaille <akim@epita.fr>
7771 * src/parse-gram.y (add_param): Strip the leading and trailing
7772 blanks from a formal argument declaration.
7773 (YY_LOCATION_PRINT): New.
7775 2004-09-24 Akim Demaille <akim@epita.fr>
7777 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
7780 2004-09-24 Akim Demaille <akim@epita.fr>
7782 * doc/bison.texinfo (Table of Symbols): Sort.
7784 2004-09-21 Akim Demaille <akim@epita.fr>
7786 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
7787 the useless parentheses.
7788 Suggested by Paul Eggert.
7790 2004-09-20 Akim Demaille <akim@epita.fr>
7792 Let the initial-action act on the look-ahead, and use it for the
7793 "initial push" (corresponding to an hypothetical beginning-of-file).
7794 And let lalr1.cc honor %initial-action.
7796 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
7798 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
7799 (Parser::Parser): Remove the ctor that used to initialize it.
7800 (Parser::parse): Like in the other skeletons, issue the "starting
7801 parse" message before any action.
7802 Honor %initial-action.
7803 Initialize the stacks with the lookahead.
7804 * data/yacc.c: Let $$ and @$ in %initial-action designate the
7806 Push them in the stacks.
7807 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
7809 2004-09-20 Akim Demaille <akim@epita.fr>
7811 * doc/bison.texinfo (Initial Action Decl): New.
7813 2004-09-20 Akim Demaille <akim@epita.fr>
7815 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
7816 clearer criterion to define it.
7817 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
7818 When reducing on an empty RHS, use the latest stacked location as
7820 yylloc is not always available.
7821 * data/glr.c: Likewise.
7822 Also, honor initial-actions.
7824 2004-09-20 Akim Demaille <akim@epita.fr>
7826 * data/yacc.c (YY_LOCATION_PRINT): New.
7827 Define when we know YYLTYPE's structure, i.e., when the default
7828 YYLLOC_DEFAULT is used.
7829 * data/c.m4 (b4_yysymprint_generate): Use it.
7830 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
7831 value of the result.
7832 (error_start_): Replace with...
7833 (error_range_): this location array.
7834 This allows to replace code relying on the implementation of
7835 locations by portable code.
7836 * data/yacc.c (yylerrsp): Replace with...
7837 (yyerror_range): this.
7838 Every time a token is popped, update yyerror_range[0], to have an
7839 accurate location for the error token.
7840 * data/glr.c (YY_LOCATION_PRINT): New.
7841 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
7842 deference a pointer.
7843 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
7844 report the location in %printers.
7846 * src/scan-skel.l: Instead of abort, report error messages to ease
7847 understanding skeleton scanning failures.
7849 2004-09-16 Akim Demaille <akim@epita.fr>
7851 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
7852 (iterator, const_iterator): these, to be more in the C++ spirit.
7853 Also, return reverse iterators so that when displaying the stack
7854 we display its bottom first.
7855 (Parser::stack_print_, Parser::reduce_print_): Match the messages
7857 We should probably use vector here though.
7859 2004-09-16 Akim Demaille <akim@epita.fr>
7861 Have more complete shift traces.
7863 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
7864 to report Shifts instead of ad hoc YYDPRINTF invocations,
7865 including for the error token.
7866 * data/lalr1.cc (symprint_): Output the location.
7867 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
7868 output the location within the %printer.
7869 Activate GLR tests, at least to make sure they compile properly.
7870 They still don't pass though.
7871 * tests/calc.at: Adjust expect verbose output, since now "Entering
7872 state..." is on a different line than the "Shifting" message.
7874 2004-09-08 Akim Demaille <akim@epita.fr>
7876 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
7877 Bison directive from the Bison file to the invocation of this
7878 macro, so that these directives are passed to
7879 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
7880 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
7881 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
7882 the extra Bison directives instead of the whole series.
7883 Change the grammar so that there are recoverable errors, and
7884 unrecoverable errors. Now we can have the parser give up before
7885 consuming the whole input. As a result we now can observe that
7886 the lookahead is freed when needed.
7887 Change the parser source to parse argv[1] instead of a hard coded
7889 Simplify yylex, and give a value and location to EOF.
7890 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
7891 passed directives already coded in the file.
7892 Add some tests to check the location of "error".
7893 For some tests, the C++ parser is correct, and not yacc.c.
7894 For other tests, they provide different, but unsatisfying, values,
7895 so keep the C++ value so that at least one parser is "correct"
7896 according to the test suite.
7897 (Actions after errors): Remove, this is subsumed by the
7898 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
7900 2004-09-06 Akim Demaille <akim@epita.fr>
7902 * data/lalr1.cc: Adjust the indentation of the labels.
7906 2004-09-06 Akim Demaille <akim@epita.fr>
7908 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
7909 argument, an informative message.
7910 Call YY_SYMBOL_PRINT.
7911 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
7912 * data/lalr1.cc (destruct_): Likewise.
7913 In addition, no longer depend on b4_yysymprint_generate and
7914 b4_yydestruct_generate to generate these functions, do it "by
7917 2004-09-03 Akim Demaille <akim@epita.fr>
7919 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
7920 invoked, yydestruct the lookahead.
7921 * tests/calc.at (Calculator $1): Update the expected lengths of
7922 traces: there is an added line for the discarded lookahead.
7923 * doc/bison.texinfo (Destructor Decl): Some rewording.
7924 Define "discarded" symbols.
7926 2004-09-02 Akim Demaille <akim@epita.fr>
7928 * data/lalr1.cc (translate_, destruct_): No reason to be static.
7930 2004-09-02 Akim Demaille <akim@epita.fr>
7932 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
7933 (YYDSYMPRINTF): Rename as...
7934 (YY_SYMBOL_PRINT): this.
7935 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
7937 Use it instead of direct symprint_ calls.
7938 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
7941 2004-09-02 Akim Demaille <akim@epita.fr>
7943 * data/lalr1.cc (b4_yysymprint_generate): New.
7944 (symprint_): New member function, defined when YYDEBUG.
7945 Use it consistently instead of token/nterm debugging output by
7947 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
7948 %printer calls to use cdebug_ when using lalr1.cc.
7950 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
7952 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
7953 with #ifdef YYDEBUG.
7955 2004-08-26 Akim Demaille <akim@epita.fr>
7957 * doc/bison.texinfo (Implementing Loops): Rename as...
7958 (Implementing Gotos/Loops): this.
7960 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
7962 Adjust to latest gnulib.
7963 * bootstrap (gnulib_modules): Add xalloc-die.
7964 Set LC_ALL=C so that file names sort consistently.
7965 Prefer the gnulib copies of gettext.m4, glibc21.m4,
7966 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
7967 uintmax_t.m4, ulonglong.m4.
7968 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
7969 po.m4 since we are now using _gl.m4 instead.
7971 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
7973 * src/scan-action.l: Remove. Scanning of semantic actions is
7974 handled in scan-gram.l.
7976 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
7978 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
7980 * src/location.h (struct): The file member is a uniqstr.
7981 (equal_boundaries): Use UNIQSTR_EQ for comparison.
7983 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
7985 Fix bug with non-%union parsers that have printers or destructors,
7986 which led to a Bison core dump. Reported by Peter Fales in
7987 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
7989 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
7990 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
7991 not to our own type.
7992 * src/output.c (symbol_destructors_output, symbol_printers_output):
7993 Don't assume %union.
7994 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
7995 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
7996 UNION-FLAG. All callers changed.
7997 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
7998 Use type char, not unsigned int, when declaring an array of char;
7999 this lets us remove a cast.
8000 (Printers and Destructors): Add non-%union test cases.
8002 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8004 * doc/bison.texinfo: Minor editorial changes, mostly to the new
8005 GLR writeups. E.g., avoid frenchspacing and the future tense,
8006 change "lookahead" to "look-ahead", and change "wrt" to "with
8009 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8011 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
8012 New sections, split off from the GLR Parsers section. Put the new
8013 Simple GLR Parser near the start of the GLR section, for clarity.
8014 Rewrite connective text.
8016 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
8018 * doc/bison.texinfo (Simple GLR Parsers): New section.
8020 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8022 * NEWS, TODO, doc/bison.texinfo:
8023 Use "look-ahead" instead of "lookahead", to be consistent.
8024 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
8025 while we're fixing "look-ahead".
8026 * src/conflicts.c (shift_set): Renamed from shiftset.
8027 (look_ahead_set): Renamed from lookaheadset.
8028 * src/print.c: Likewise.
8029 * src/getargs.c (report_args): Add "look-ahead" as the new canonical

8047 * README: Update location of patched M4 distribution.
8049 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
8051 Don't assume the C++ compiler takes the same arguments as the C compiler
8053 * configure.ac (O0CXXFLAGS): New var.
8054 * tests/atlocal.in (CXXFLAGS): Use it.
8056 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>

8072 C++ compiler. (trivial change)
8074 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
8076 Spent a few hours checking out which prerequisite versions the
8077 current sources actually require. I went all the way back to
8078 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8079 a seemingly endless set of combinations of versions more recent
8080 than that. The bottom line is that the current sources require
8081 fairly recent versions of the build tools, and it'll be some work
8083 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
8084 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
8085 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
8086 Add comments explaining why those particular versions are
8089 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
8090 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
8091 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
8093 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
8094 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
8096 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8098 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
8099 0.11.5. Suggested by Bruno Haible.
8100 * bootstrap: Remove gettext version checking.
8102 * doc/bison.texinfo (Decl Summary): Also mention that %union
8103 can depend on prerequisite types. Problem reported by Tim
8106 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8108 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
8109 * README-alpha: Don't tell people not to package this.
8111 * bootstrap: Don't assume $(...) works; use `...` instead.
8112 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
8115 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
8116 put into the -d output file, and mention what to do if YYSTYPE is
8119 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8121 Undo change made earlier today: it caused autopoint to not bring
8122 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
8125 * bootstrap: Check that gettext version matches what's in
8126 configure.ac. Warn users to ignore robots.txt ERROR 404.
8127 * bootstrap: Undo today's earlier change (logged below).
8128 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
8130 The gettext version checking is causing more trouble than it's
8131 curing; remove it. Problem reported by Paul Hilfinger.
8133 * bootstrap: Issue a warning that one can expect a message
8134 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
8135 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
8137 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
8139 Ensure that the C++ compiler used for testing actually works on a
8140 simple test program; if not, skip the C++-related tests. Problem
8141 reported by Vin Shelton in:
8142 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
8144 * m4/cxx.m4: New file.
8145 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
8146 * tests/atlocal.in (BISON_CXX_WORKS): Add.
8147 * tests/local.at (AT_COMPILE_CXX): Use it.
8149 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
8151 * data/glr.c (yylloc): Output this macro even if locations are not
8152 being generated, as the GLR parser needs it even in that case.
8153 Problem reported by Troy A. Johnson
8154 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
8156 * configure.ac (AC_INIT): Update to 1.875e.
8158 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
8160 * NEWS: Version 1.875d.

8162 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
8164 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
8165 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
8166 lalr1.cc runs afoul of the first, and the last two are no longer
8167 supported by GCC 3.4.0.
8168 * README: Mention GNU m4 1.4 or later; mention m4 patches.
8169 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
8171 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>

8194 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
8195 Fix typo by replacing $1 with $option.
8196 Remove more 'intl'-related files.
8197 Don't DEFUN AM_INTL_SUBDIR twice.
8199 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,

8207 * src/.cvsignore: Add *.output.
8209 * src/parse-gram.y: Put copyright notice inside %{ %} so it
8210 gets copied to the output file.
8212 2004-04-28 Paul Eggert <eggert@twinsun.com>
8214 Get files from the gnulib and po repositories, instead of relying
8215 on them being in our CVS. Upgrade to latest versions of gnulib
8218 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
8219 * bootstrap: Bootstrap from gnulib and po repositories.
8220 Much of this code was stolen from GNU diff and GNU tar's bootstrap.

8227 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
8229 (AC_ISC_POSIX): Remove; we no longer support this
8230 ancient OS, as it gets in the way of latest Autoconf & gnulib.
8231 (AC_HEADER_STDC): Remove: we now assume C89 or better.
8232 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
8233 Do not check for C89 headers, except for locale.h which is used
8234 by the Yacc library and must port to K&R hosts.
8235 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
8236 Do not check for C89 functions, except for setlocale which is
8237 used by the Yacc library.
8238 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
8239 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

8248 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
8249 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):

8253 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
8254 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
8256 * src/files.c: Include gnulib's xstrndup.h.
8258 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
8259 (REALLOC): Use xnrealloc, for likewise.
8260 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.

8285 Remove, as these files are now generated automatically
8286 by bootstrap or automake.

8312 support it. (The latest stable gzip doesn't.)
8314 2004-04-27 Paul Eggert <eggert@twinsun.com>
8316 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
8317 case, as stos_ is now used by destructors due to the 2004-02-09
8320 Remove more K&R C support.

8344 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
8345 so that this include file can stand alone.
8346 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
8347 does this now. Include subpipe.h first after config.h, to
8348 test whether it can stand alone.
8350 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
8351 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
8354 * tests/synclines.at (%union synch line): Put a dummy member in
8355 the union, because empty unions aren't allowed in C. Caught
8358 2004-04-13 Jim Meyering <jim@meyering.net>
8360 * src/conflicts.c (conflicts_print): Correct format string typo:

8421 Use expected_sr_conflicts in place of expected_conflicts.
8422 Warn if expected_rr_conflicts used in non-GLR parser.
8424 * doc/bison.texinfo: Add documentation for %expect-rr.
8426 2004-03-08 Paul Eggert <eggert@gnu.org>

8443 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
8444 compilers. This fixes a problem with Intel's C++ compiler being
8445 chatty, reported by Guido Trentalancia in
8446 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.

8460 error_start_ when erroneous token are discarded.
8461 (Parser::parse) <yyerrlab1>: Compute the location of the error
8462 token so that it covers all the discarded tokens.
8463 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
8464 it can be called with `%skeleton "lalr1.cc"', and do that.
8466 2004-02-02 Paul Eggert <eggert@twinsun.com>
8468 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
8469 $(top_srcdir)/lib and ../lib. This fixes a bug reported
8470 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
8471 There's no need to mention top_builddir since Automake does that
8473 (INCLUDES): Remove, as Automake says it's obsolescent.
8474 Contents migrated into AM_CPPFLAGS as described above.
8475 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
8477 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>

8486 resulting parsers are compilable with C++.
8488 2003-12-23 Paul Eggert <eggert@twinsun.com>
8490 * config/depcomp, config/install-sh: Sync with Automake 1.8.
8491 * src/output.c (output_skeleton): Rename local var.
8492 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
8493 Bison tokens, as this runs afoul of the 2003-10-07 change that
8494 disallowed NUL bytes in character constants or string literals.
8496 * tests/local.at: Require Autoconf 2.59's Autotest.
8497 * tests/testsuite.at: Don't include local.at, since we now assume
8498 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
8500 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
8501 multiple inclusion warnings.
8503 2003-12-02 Akim Demaille <akim@epita.fr>

8519 literals, unfortunately.
8520 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
8521 Complain about NUL bytes in character constants or string literals.
8523 2003-10-05 Paul Eggert <eggert@twinsun.com>
8525 * NEWS: Don't document %no-default-prec, as it's still
8527 * doc/bison.texinfo: Document %no-default-prec only if
8528 the defaultprec flag is set. Normally it's not.
8530 2003-10-04 Paul Eggert <eggert@twinsun.com>
8532 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
8533 non-modifiable lvalue, instead of a modifiable one.
8534 * doc/bison.texinfo (Actions): Document that $$ can
8535 be assigned to. Do not claim that $$ and $N are
8536 array element references: user code should not rely on this.
8538 2003-10-01 Paul Eggert <eggert@twinsun.com>
8540 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

8551 * src/print_graph.c (print_graph): Adjust.
8553 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
8554 and Paul Eggert <eggert@twinsun.com>
8556 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
8557 Table of Symbols): Document %default-prec.
8558 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
8559 (grammar_declaration): Set default_prec on %default-prec.

8574 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
8577 2003-08-26 Akim Demaille <akim@epita.fr>
8579 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
8580 "<\#" to avoid magic from Gnus when posting parts of this script.

8589 2003-08-25 Akim Demaille <akim@epita.fr>
8591 * config/announce-gen, Makefile.cfg: New.
8592 * Makefile.am: Adjust.
8593 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
8594 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
8596 2003-08-25 Akim Demaille <akim@epita.fr>
8598 When reducing initial empty rules, Bison parser read an initial
8599 location that is not defined. This results in garbage, and that
8600 affects Bison's own parser. Therefore we need (i) to extend Bison
8601 to support a means to initialize this location, and (ii) to use
8602 this CVS Bison to fix CVS Bison's parser.
8604 * src/reader.h, reader.c (epilogue_augment): Remove, replace
8606 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
8607 * src/parse-gram.y: Adjust.
8608 (%initial-action): New.
8609 (%error-verbose): Since we require CVS Bison, there is no reason
8611 * src/scan-gram.l: Adjust.
8612 * src/Makefile.am (YACC): New, to make sure we use our own parser.
8613 * data/yacc.c (yyparse): Use b4_initial_action.
8615 2003-08-25 Akim Demaille <akim@epita.fr>
8617 * doc/bison.texinfo: Don't promote stdout for error messages.
8619 2003-08-25 Akim Demaille <akim@epita.fr>
8621 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
8622 From Alexandre Duret-Lutz.

8628 2003-08-25 Akim Demaille <akim@epita.fr>
8630 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
8633 2003-08-25 Akim Demaille <akim@epita.fr>
8635 * data/lalr1.cc (Parser::reduce_print_): New.
8638 2003-08-25 Akim Demaille <akim@epita.fr>
8640 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
8641 error recovery loops. This patch is based on
8642 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
8643 Also, augment the similarity between lalr1.cc and yacc.c.
8644 Note: the locations of error recovery rules are not correct yet.
8646 * data/lalr1.cc: Comment changes to augment the similarity between
8647 lalr1.cc and yacc.c.
8648 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
8649 (yyerrlab1): Remove, but where it used to be (now the bottom part of
8650 yyerrlab), when hitting EOF, pop the whole stack here instead of
8651 merely falling thru the default error handling mechanism.
8652 (yyerrorlab): New label, with the old contents of YYERROR,
8653 plus the following change: pop the stack of rhs corresponding
8654 to the production that invoked YYERROR. That is how Yacc
8655 behaves (required by POSIX).
8656 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
8659 2003-08-25 Akim Demaille <akim@epita.fr>
8661 Tune local.at so that people can "autom4te -l autotest calc.at -o
8662 calc" for instance, to extract a sub test suite.
8664 * tests/testsuite.at: Move the initialization, Autotest version
8665 requirement, and AT_TESTED invocation into...
8666 * tests/local.at: here.
8667 * tests/testsuite.at: Include it for compatibility with Autoconf
8669 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
8672 2003-08-04 Paul Eggert <eggert@twinsun.com>
8674 Rework code slightly to avoid gcc -Wtraditional warnings.
8675 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
8676 The returned value is now stored in *YY0. All callers changed.
8677 * src/output.c (merge_output): Adjust to the above change.
8679 2003-07-26 Paul Eggert <eggert@twinsun.com>
8681 * data/glr.c (YYASSERT): New macro.
8682 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
8683 yyresolveStates, yyprocessOneStack):
8684 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
8685 Derived from a suggestion by Frank Heckenbach.
8687 2003-07-25 Paul Eggert <eggert@twinsun.com>
8689 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
8690 for portability to K&R C (after ansi2knr, presumably). See
8691 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
8692 by Frank Heckenbach, though I have omitted the structure-initialization
8693 part of his glr-knr.diff patch since I recall that the Portable
8694 C Compiler didn't require that change.
8696 Let the user specify how to allocate and free memory.
8697 Derived from a suggestion by Frank Heckenbach in
8698 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
8699 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
8700 All uses of free, malloc, realloc changed to use these macros,
8701 and unnecessary casts removed.
8702 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
8704 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
8706 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
8707 use s.empty() rather than s == "" to test for empty string; see
8708 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
8711 2003-06-25 Akim Demaille <akim@epita.fr>
8713 * config/depcomp, config/install-sh: Update from masters.
8715 2003-06-20 Paul Eggert <eggert@twinsun.com>
8717 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
8718 and return properly parenthesized result.
8719 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
8720 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8721 Remove unnecessary parentheses from uses.
8722 * doc/bison.texinfo (Location Default Action): Describe the
8723 conventions for parentheses.
8725 2003-06-19 Paul Eggert <eggert@twinsun.com>
8727 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
8728 yyreportTree): Do not assume that size_t is the same width as int,
8729 when printing sizes. Print sizes using an unsigned format.
8730 Problem reported by Frank Heckenbach in
8731 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
8733 Port to Forte Developer 7 C compiler.
8734 * data/glr.c (struct YYLTYPE): If locations are not being used,
8735 declare a single dummy member, as empty structs do not conform
8737 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
8738 the Forte Developer 7 C compiler complains that end-of-loop
8739 code is not reached.
8741 2003-06-17 Paul Eggert <eggert@twinsun.com>
8743 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
8744 avoid warnings from picky compilers about redefinition of PARAMS.
8746 2003-06-17 Paul Eggert <eggert@twinsun.com>
8750 * NEWS: Document 1.875b.
8752 * lib/bbitset.h: Do not include config.h; that's the includer's job.
8753 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
8754 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
8755 Don't use 'index' in comments, as it's a builtin fn on some hosts.
8756 * lib/bitset_stats.c: Include gettext.h unconditionally, as
8757 per recent gettext manual's suggestion.
8758 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
8759 Use prototypes, not old-style definitions.
8760 * lib/lbitset.c (lbitset_unused_clear): Likewise.
8761 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
8762 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
8763 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
8764 vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,
8765 vbitset_xor, vbitset_xor_cmp, vbitset_and_or, vbitset_and_or_cmp,
8766 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
8767 vbitset_or_and_cmp, vbitset_copy): Likewise.
8769 * lib/libiberty.h: Do not include config.h; that's the includer's job.
8770 Do not include <stdlib.h>.
8771 (PARAMS): Define unconditionally for C89.
8772 (ATTRIBUTE_NORETURN): Remove.
8773 (ATTRIBUTE_UNUSED): Define unconditionally.
8775 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
8776 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
8777 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
8778 * lib/vbitset.c, lib/vbitset.h: New files.
8779 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
8780 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
8783 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
8784 `How Can I Reset @code{yyparse}', since texinfo does not allow
8785 arbitrary @ in node names.
8787 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
8788 shouldn't be needed according to the gettext 0.12.1 documentation
8789 but which seem to be needed anyway: codeset.m4 glibc21.m4
8790 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
8791 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
8792 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
8794 * lib/.cvsignore: Add stdbool.h.
8795 * m4/.cvsignore: Add nls.m4, po.m4.
8797 Upgrade to CVS gnulib.
8798 * stdbool_.h: File renamed from stdbool.h.in.
8799 * configure.ac (AM_STDBOOL_H): Invoke this instead of
8801 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
8802 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
8803 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
8804 (MOSTLYCLEANFILES): New var.
8805 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
8806 (stdbool.h): New rule.
8807 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
8808 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
8809 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
8810 m4/quote.m4: Upgrade to today's gnulib.
8812 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
8813 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
8814 the tests right now.
8815 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
8816 yyerror are declared before use; C99 requires this.
8818 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8820 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
8822 (yyrecoverSyntaxError): Correct the logic for setting and testing
8824 Correct comment on handling EOF.
8825 Allow states with only a default reduction, rather than failing
8826 (I can't quite reconstruct why these were not allowed before).
8828 Fixes to avoid problem that $-N rules in GLR parsers can cause
8829 buffer overruns, corrupting state.
8831 * src/output.c (prepare_rules): Output max_left_semantic_context
8833 * src/reader.h (max_left_semantic_context): New variable declaration.
8834 * src/scan-gram.l (max_left_semantic_context): Define.
8835 (handle_action_dollar): Update max_left_semantic_context.
8836 * data/glr.c (YYMAXLEFT): New definition.
8837 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
8838 (yyresolveAction): Ditto.
8840 Fixes to problems with location handling in GLR parsers reported by
8841 Frank Heckenbach (2003/06/05).
8843 * data/glr.c (YYLTYPE): Make trivial if locations not used.
8844 (YYRHSLOC): Add parentheses, and define only if locations used.
8845 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
8847 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
8848 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
8850 * tests/cxx-type.at: Exercise location information; update tests
8851 to differentiate output with and without locations.
8852 Remove forward declarations of yylex and yyerror---caused errors
8853 because default YYLTYPE not yet defined.
8854 Change semantic actions to compute strings, rather than printing
8855 them directly (to test proper passing of semantics values). Change
8856 output to prefix notation and update test data and expected results.
8857 (yylex): Track locations.
8858 (stmtMerge): Return value rather than printing, and include arguments
8861 2003-06-03 Paul Eggert <eggert@twinsun.com>
8863 Avoid warnings generated by GCC 2.95.4 when Bison is
8864 configured with --enable-gcc-warnings.
8865 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
8866 yy::]b4_parser_class_name[::translate_,
8867 yy::Stack::operator[] (unsigned),
8868 yy::Stack::operator[] (unsigned) const,
8869 yy::Slice::operator[] (unsigned),
8870 yy::Slice::operator[] (unsigned) const):
8871 Rename local vars to avoid warnings.
8872 * tests/glr-regression.at (Improper handling of embedded actions
8873 and $-N in GLR parsers): Remove unused local variable from yylex.
8874 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
8875 (void) as arg when not pure, since we now assume C89 when building
8876 Bison. Pacify GCC by using parameter.
8878 2003-06-02 Paul Eggert <eggert@twinsun.com>
8880 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
8881 yy::Location::lines, yy::Location::columns): Rename arguments
8882 to avoid shadowing; this removes a warning generated by GCC 3.3.
8884 2003-06-01 Paul Eggert <eggert@twinsun.com>
8886 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
8887 to g++, as GCC 3.3 complains if you do it.
8888 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
8889 everything that WARNING_CFLAGS has, except omit warnings
8890 not suitable for C++.
8891 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
8892 * tests/atlocal.in (CXXFLAGS): New var.
8893 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
8895 Fix a GLR parser bug I reported in February; see
8896 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
8897 The problem was that GLR parsers did not conform to the C standard,
8898 because actions like { $1 = $2 + $3; } expanded to expressions
8899 that invoked YYFILL in separate subexpressions, and YYFILL assigned
8900 to a local variable. The C standard says that expressions
8901 like (var = f ()) + (var = f ()) have undefined behavior.
8902 Another problem was that GCC sometimes issues warnings that
8903 yyfill and its parameters are unused.
8905 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
8907 (yyfill): New function.
8909 (yyuserAction): Change type of yynormal to bool, so that it matches
8910 the new yyfill signature. Mark it as possibly unused.
8913 Follow up on a bug I reported in February, where a Bison-generated
8914 parser can loop. Provide a test case and a fix for yacc.c. I
8915 don't have a fix for lalr1.cc or for glr.c, unfortunately.
8916 The original bug report is in:
8917 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
8919 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
8920 macro's size was becoming unwieldy.
8921 (yyerrlab): Do not discard an empty lookahead symbol, as this
8922 might destroy garbage.
8923 (yyerrorlab): New label, with the old contents of YYERROR,
8924 plus the following change: pop the stack of rhs corresponding
8925 to the production that invoked YYERROR. That is how Yacc
8926 behaves, and POSIX requires this behavior.
8927 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
8928 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
8929 Define 'alarm' to do nothing if unistd.h is not available.
8930 Add a new rule "exp: '-' error;" to test the above change to
8931 data/yacc.c. Use 'alarm' to abort any test taking longer than
8932 10 seconds, as it's probably looping.
8933 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
8934 Also, the new yacc.c generates two fewer diagnostics for an
8937 2003-05-24 Paul Eggert <eggert@twinsun.com>
8939 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
8940 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
8941 This fixes a problem reported by John Bowman when the Compaq/HP
8942 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
8944 * data/yacc.c (union yyalloc): Likewise.
8945 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
8947 Switch from 'int' to 'bool' where that makes sense.
8949 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
8950 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,

8952 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
8953 Return or accept bool, not int. All callers changed.

8973 lbitset_xor_cmp): Likewise.
8974 * lib/bbitset.h: Include <stdbool.h>.
8975 (struct bitset_vtable): The following members now return bool, not
8976 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,

9008 * config/install-sh: Sync from automake 1.7.5.
9010 2003-05-14 Paul Eggert <eggert@twinsun.com>
9012 * src/parse-gram.y (rules_or_grammar_declaration): Require a
9013 semicolon after a grammar declaration, in the interest of possible
9014 future changes to the Bison input language.
9015 Do not allow a stray semicolon at the start of the grammar.
9016 (rhses.1): Allow one or more semicolons after any rule, including
9017 just before "|" as required by POSIX.
9018 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
9021 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
9023 %parse-param support for lalr1.cc.
9025 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
9026 b4_cc_constructor_calls, b4_cc_constructor_call,
9027 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
9029 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
9030 parse-param arguments.
9031 (yy::b4_parser_class_name): Declare instance variables to
9032 hold parse-param arguments.
9033 * tests/calc.at: s/value/semantic_value/ because value clashes
9034 with a member of yy::b4_parser_class_name. Adjust C++ code
9035 to handle %parse-param. Enable %parse-param test in C++.
9037 2003-05-12 Paul Eggert <eggert@twinsun.com>
9039 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
9040 English a bit. Fix fclose typo. Change "const char" to "char
9041 const", and use ANSI C rather than K&R for "main". Suggest
9042 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
9043 and suggest yy_switch_to_buffer.
9045 2003-05-05 Paul Eggert <eggert@twinsun.com>
9047 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
9048 C89. This avoids a diagnostic on compilers that define __STDC__
9049 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
9050 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9052 2003-05-03 Paul Eggert <eggert@twinsun.com>
9054 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
9055 Do not overrun array bounds.
9056 This should fix a bug reported today by Olatunji Oluwabukunmi in
9057 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
9059 2003-04-29 Akim Demaille <akim@epita.fr>
9061 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
9062 * src/getargs.c, src/getargs.h: here, as bool, not int.
9063 (nondeterministic_parser): New.
9064 * src/parse-gram.y, src/scan-gram.l: Support
9065 %nondeterministic-parser.
9066 * src/output.c (prepare): Use nondeterministic_parser instead
9067 of glr_parser where appropriate.
9068 * src/tables.c (conflict_row, action_row, save_row)
9069 (token_actions, token_actions, pack_vector): Ditto.
9071 2003-04-29 Akim Demaille <akim@epita.fr>
9073 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
9075 2003-04-29 Akim Demaille <akim@epita.fr>
9077 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
9078 with %pure-parser and %locations to exercise the patch from Yakov
9081 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
9083 * data/yacc.c: (b4_lex_param): Corrected for the case where
9084 %lex-param is provided and %pure-parser isn't.
9086 2003-04-27 Paul Eggert <eggert@twinsun.com>
9088 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
9089 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
9090 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
9091 if it is not defined.
9092 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
9094 2003-04-26 Paul Eggert <eggert@twinsun.com>
9096 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
9097 Declare to be of type suitable for the ninf value itself, not of
9098 type suitable for the corresponding table, since the latter might
9099 be unsigned but the ninf value might be negative. This fixes a
9100 bug reported by Alexandre Duret-Lutz in
9101 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
9103 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
9104 invokes it. We shouldn't invoke it twice because it will attempt
9105 to put error.o in the archive twice. This fixes a glitch reported
9106 by Martin Mokrejs in
9107 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9109 2003-04-21 Paul Eggert <eggert@twinsun.com>
9111 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
9114 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
9116 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
9117 Fix obvious typo that results in uncompilable GLR parsers
9118 when both %pure-parser and %locations are used. (trivial change)
9120 2003-04-17 Paul Eggert <eggert@twinsun.com>
9122 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
9123 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
9124 Do not insert the expected token via unput, as this runs afoul
9125 of a POSIX-compatibility bug in flex 2.5.31.
9126 All uses changed to BEGIN the parent state,
9127 since we no longer insert the expected token via unput.
9128 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
9129 that is no longer emitted after the above change.
9131 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
9132 the first one. This change is from Paul Hilfinger, and it fixes
9133 regression reported by Werner Lemberg in
9134 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
9136 (resolve_sr_conflict): Don't invoke state_errs_set
9137 unless one or more tokens have been explicitly made errors.
9138 Otherwise, the above change causes Bison to abort.
9140 * tests/existing.at (GNU pic Grammar): New test case, taken from
9143 2003-03-31 Akim Demaille <akim@epita.fr>
9145 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
9147 2003-03-31 Akim Demaille <akim@epita.fr>
9149 * src/output.c (prepare_symbols): Avoid trailing spaces in the
9152 2003-03-31 Akim Demaille <akim@epita.fr>
9154 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
9155 From Paul Hilfinger.
9157 2003-03-29 Akim Demaille <akim@epita.fr>
9159 * m4/error.m4: Do not put under dynamic conditions some code which
9160 expansion is under static control.
9162 2003-03-29 Akim Demaille <akim@epita.fr>
9164 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
9166 2003-03-29 Akim Demaille <akim@epita.fr>
9168 * doc/bison.texinfo (Strings are Destroyed): New.
9170 2003-03-13 Paul Eggert <eggert@twinsun.com>
9172 * .cvsignore: Add configure.lineno.
9173 * src/.cvsignore: Add yacc.
9174 * tests/.cvsignore: Add testsuite.log.
9175 * doc/fdl.texi: Sync with latest FSF version.
9177 2003-03-12 Paul Eggert <eggert@twinsun.com>
9179 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
9180 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
9181 cursor, instead of leaving it undefined. This fixes a bug
9182 reported by Tim Van Holder in
9183 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
9184 * tests/input.at (Torturing the Scanner): Test the scanner on
9185 an empty input file, which was Tim Van Holder's test case.
9187 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
9188 <sys/resource.h> can be included, include sys/time.h and
9189 sys/times.h first, if available. This works around the SunOS
9190 4.1.4 porting bug reported by Bruce Becker in
9191 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
9193 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
9194 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
9197 Merge changes from gnulib. This was prompted because the CVS
9198 snapshot didn't build on Solaris 7 due to strnlen problems.
9200 These changes need to be merged back into gnulib:
9201 * lib/hash.c: Include <stdbool.h> unconditionally.
9202 * m4/onceonly.m4 (m4_quote): New macro.
9203 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
9204 Quote AC_FOREACH variable-expansions properly.
9205 The 2003-01-03 obstack.h change also needs merging.
9206 {end of changes requiring merging}
9208 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
9209 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
9210 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,

9212 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
9213 New files, imported from gnulib.
9214 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
9217 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
9218 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current

9226 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
9227 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
9228 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
9229 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
9230 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
9231 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
9232 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
9233 (jm_PREREQ_ARGMATCH): Remove.
9234 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
9235 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
9237 * src/system.h: Include <stdbool.h> unconditionally.
9239 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
9240 assuming at least C89 in the bitset code for some time now.
9242 2003-03-03 Akim Demaille <akim@epita.fr>
9246 2003-03-02 Akim Demaille <akim@epita.fr>
9248 * doc/bison.texinfo (Table of Symbols): Reactivate the
9249 documentation for %lex-param, and %parse-param.
9251 2003-03-02 Akim Demaille <akim@epita.fr>
9253 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
9254 generate verbose error messages.
9255 Use the number of tokens as an upper bound in yytname, as it
9256 cannot be a non terminal.
9258 2003-03-02 Akim Demaille <akim@epita.fr>
9260 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
9263 2003-03-02 Akim Demaille <akim@epita.fr>
9265 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
9266 Use them to exercise yycheck overrun.
9267 Based on Andrew Suffield's grammar.
9269 2003-03-02 Akim Demaille <akim@epita.fr>
9271 Create tests/local.at for Bison generic testing macros.
9273 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
9274 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
9276 * tests/calc.at (AT_CHECK_CALC): Adjust.
9277 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
9278 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
9279 * tests/local.at: here.
9280 (AT_COMPILE_CXX): Tags the tests using it as c++.
9281 Ignore the test if CXX is not functional.
9283 2003-03-01 Paul Eggert <eggert@twinsun.com>
9285 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
9286 not loc->end, since loc->end might contain garbage and this leads
9287 to undefined behavior on some platforms.
9288 (id_loc, token_start): Use (IF_LINTed) initial values that do not
9289 depend on *loc, so that the reader doesn't give the the false
9290 impression that *loc is initialized.
9291 (<INITIAL>"%%"): Do not bother setting code_start, since its value
9292 does not survive the return.
9294 2003-03-01 Akim Demaille <akim@epita.fr>
9296 * src/scan-gram.l (code_start): Always initialize it when entering
9297 into yylex, as SC_EPILOGUE is activated *before* the corresponding
9298 yylex invocation. An alternative would be making it static, but
9299 then it starts with the second %%'s beginning, instead of its end.
9301 2003-02-28 Paul Eggert <eggert@twinsun.com>
9303 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
9304 around a UnixWare 7.1.1 porting bug reported by John Hughes in
9305 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
9307 2003-02-26 Paul Eggert <eggert@twinsun.com>
9309 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
9310 Remove Sequent/Pyramid discussion (nobody uses them any more).
9311 Merge VMS and MS-DOS discussion; these ports may well be dead
9312 but let's keep mentioning them for now. Put <> around email
9313 addresses. Add copyright notice.
9315 2003-02-24 Paul Eggert <eggert@twinsun.com>
9317 * data/glr.c (yy_reduce_print): yylineno -> yylno,
9318 to avoid collision with flex use of yylineno.
9319 Problem reported by Bruce Lilly in
9320 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

9328 * data/lalr1.cc: Use temporary variables instead of casts to
9329 change integer types.
9330 Suggested by Paul Eggert.
9332 2003-02-21 Akim Demaille <akim@epita.fr>
9334 * doc/bison.texinfo: Use "location" consistently to refer to @n,
9335 to avoid confusions with lalr1.cc's notion of Position.
9336 Suggested by Paul Eggert.
9338 2003-02-20 Akim Demaille <akim@epita.fr>
9340 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
9341 before initial_columns.
9342 (location.hh): Use consistent variable names when defining the
9344 Use "last" so that we subtract from Positions, not from unsigned.
9346 2003-02-20 Akim Demaille <akim@epita.fr>
9348 * data/lalr1.cc (position.hh): New subfile, including the extended
9349 and Doxygen'ed documentation of class Position.
9350 (location.hh): Use it.
9351 Document a` la Doxygen.
9352 With the help of Benoit Perrot.
9354 2003-02-20 Akim Demaille <akim@epita.fr>
9356 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define

9362 yy::Parser::print_ when not %locations.
9363 Activate more lalr1.cc tests.
9365 2003-02-19 Akim Demaille <akim@epita.fr>
9367 * data/lalr1.cc: When displaying a line number, be sure to make it

9377 2003-02-19 Akim Demaille <akim@epita.fr>
9379 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
9380 error recovery, mixing with/without pops and discarding of the
9383 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
9385 2003-02-17 Paul Eggert <eggert@twinsun.com>
9387 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
9388 * tests/testsuite.at (AT_COMPILE): Use them.

9524 Changes in response to error report by S. Eken: GLR mode does not
9525 handle negative $ indices or $ indices in embedded rules correctly.

9536 Remove dummy use of yystack, as there is now a guaranteed use.
9537 (yydoAction): Modify to allow incremental move of semantic values
9538 to rhs array when in GLR mode.
9539 (yyresolveAction): Ditto.
9540 (yyglrShiftDefer): Update comment.
9541 (yyresolveStates): Use X == NULL for pointers, not !X.
9542 (yyglrReduce): Ditto.
9545 * tests/glr-regr1.at: Rename to ...
9546 * tests/glr-regression.at: Add new regression test for the problems
9547 described above (adapted from S. Eken).
9548 Update copyright notice.
9549 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
9550 * tests/Makefile.am: Ditto.
9552 2003-01-28 Paul Eggert <eggert@twinsun.com>
9554 * data/lalr1.cc: Do not use @output_header_name@ unless
9555 b4_defines_flag is set. This fixes two bugs reported by
9557 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
9558 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
9560 2003-01-21 Paul Eggert <eggert@twinsun.com>
9562 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
9563 we don't need to worry about yyerrlab1 being reported as an
9564 "unused label" by non-GCC C compilers. The downside is that if
9565 locations are used then a couple of statements are duplicated each
9566 time YYERROR is invoked, but the upside is that the warnings
9568 (yyerrlab1): Move code to YERROR.
9569 (yyerrlab2): Remove. Change uses back to yyerrlab1.
9570 This reverts some of the 2002-12-27 change.
9572 2003-01-17 Paul Eggert <eggert@twinsun.com>
9574 * src/output.c (symbol_printers_output): Fix typo that led
9575 to core dump. Problem reported by Antonio Rus in
9576 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
9578 2003-01-13 Akim Demaille <akim@epita.fr>,
9579 Quoc Peyrot <chojin@lrde.epita.fr>,
9580 Robert Anisko <anisko_r@lrde.epita.fr>
9582 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
9583 when the stacks contain one element, as the loop would otherwise
9584 free the last state, and then use the top state (the one we just
9585 popped). This means that the initial elements will not be freed
9586 explicitly, as is the case in yacc.c; it is not a problem, as
9587 these elements have fake values.
9589 2003-01-11 Paul Eggert <eggert@twinsun.com>
9591 * NEWS: %expect-violations are now just warnings, reverting
9592 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
9593 bootstrapping problem reported by Matthias Klose; see
9594 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
9595 * src/conflicts.c (conflicts_print): Likewise.
9596 * tests/conflicts.at (%expect not enough, %expect too much,
9597 %expect with reduce conflicts): Likewise.
9598 * doc/bison.texinfo (Expect Decl): Document this. Also mention
9599 that the warning is enabled if the number of conflicts changes
9600 (not necessarily increases).
9602 * src/getargs.c (version): Update copyright year.
9604 2003-01-09 Akim Demaille <akim@epita.fr>
9606 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
9608 2003-01-08 Paul Eggert <eggert@twinsun.com>
9610 * Makefile.maint (WGETFLAGS):
9611 New macro, containing "-C off" to disable proxy caches.
9612 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
9613 (rel-check): Use $(WGET) instead of wget.
9615 2003-01-06 Paul Eggert <eggert@twinsun.com>
9617 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
9618 the GLR paper of Scott, Johnstone and Hussain.
9620 2003-01-04 Paul Eggert <eggert@twinsun.com>
9622 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
9623 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
9624 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
9625 (EXTRA_LIBRARIES): New var, for liby.a.
9626 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
9627 (EXTRA_SCRIPTS): New var, for yacc.
9629 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
9630 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
9631 Problem reported by Nelson H. F. Beebe.
9633 2003-01-03 Paul Eggert <eggert@twinsun.com>
9635 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
9636 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
9637 when compiling Bison 1.875's `bitset bset = obstack_alloc
9638 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
9640 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
9641 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
9642 grow to a huge size with typical invocation.
9644 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
9645 Use the pattern recommended by Autoconf 2.57, except also protect
9646 against double-definition.
9647 * src/system.h: Likewise.
9648 Portability issues reported by Nelson H. F. Beebe.
9650 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
9651 All uses changed. Provide a definition in both C and C++.
9652 (yytrue, yyfalse): Define even if defined (__cplusplus).
9654 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
9655 Reported by Nelson H. F. Beebe.
9657 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
9659 2003-01-02 Paul Eggert <eggert@twinsun.com>
9661 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
9662 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
9663 Bug reported by Nelson H. F. Beebe.
9665 2003-01-01 Paul Eggert <eggert@twinsun.com>
9669 2002-12-30 Paul Eggert <eggert@twinsun.com>
9671 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
9673 (<INITIAL>","): Here. This causes stray "," to be treated
9676 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
9677 last brace in braced code when not in Yacc mode, for compatibility
9678 with Bison 1.35. This resurrects the 2001-12-15 patch to
9681 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
9682 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
9684 2002-12-28 Paul Eggert <eggert@twinsun.com>
9686 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
9687 that of SYM's type. This fixes Debian bug 168069, reported by
9690 2002-12-28 Paul Eggert <eggert@twinsun.com>
9694 Switch back to the Yacc style of conflict reports, undoing some
9695 of the 2002-07-30 change.
9696 * doc/bison.texinfo (Understanding): Use Yacc style for
9697 conflict reports. Also, use new way of locating rules.
9698 * src/conflicts.c (conflict_report):
9699 Renamed from conflict_report_yacc, removing the old
9700 'conflict_report'. Translate the entire conflict report at once,
9701 so that we don't assume that "," has the same interpretation in
9703 (conflicts_output): Use Yacc-style conflict report for each state,
9704 instead of our more-complicated style.
9705 (conflicts_print): Use Yacc-style conflict report, except print
9706 the input file name when not emulating Yacc.
9707 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
9708 Conflicted Reduction, %expect not enough, %expect too much,
9709 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
9710 * tests/existing.at (GNU Cim Grammar): Likewise.
9711 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
9713 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
9714 fatal): Don't invoke fflush; it's not needed and it might even be
9715 harmful for stdout, as stdout might not be open.
9716 * src/reduce.c (reduce_print): Likewise.
9718 2002-12-27 Paul Eggert <eggert@twinsun.com>
9720 Fix a bug where error locations were not being recorded correctly.
9721 This problem was originally reported by Paul Hilfinger in
9722 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
9724 * data/yacc.c (yyparse): New local var yylerrsp, to record the
9725 top of the location stack's error locations.
9726 (yyerrlab): Set it. When discarding a token, push its location
9727 onto yylerrsp so that we don't lose track of the error's end.
9728 (yyerrlab1): Now is only the target of YYERROR, so that we can
9729 properly record the location of the action that failed. For GCC
9730 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
9731 GCC warning about yyerrlab1 being unused if YYERROR is unused.
9732 (yyerrlab2): New label, which yyerrlab now falls through to.
9733 Compute the error's location by applying YYLLOC_DEFAULT to
9734 the locations of all the symbols that went into the error.
9735 * doc/bison.texinfo (Location Default Action): Mention that
9736 YYLLOC_DEFAULT is also invoked for syntax errors.
9737 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9738 Error locations include the locations of all the tokens that were
9739 discarded, not just the last token.
9741 2002-12-26 Paul Eggert <eggert@twinsun.com>
9743 * src/files.c: Include quote.h.
9744 (compute_output_file_names): Warn if we detect conflicting
9745 outputs to the same file. This should catch the misunderstanding
9746 exemplified by Debian Bug 165349, reported by Bruce Stephens..
9748 * src/conflicts.c (conflicts_print): If the user specifies
9749 "%expect N", report an error if there are any reduce/reduce
9750 conflicts. This is what the manual says should happen.
9751 This fixes Debian bug 130890, reported by Anthony DeRobertis.
9752 * tests/conflicts.at (%expect with reduce conflicts): New test.
9754 Don't use m4_include on relative file names, as it doesn't work as
9755 desired if there happens to be a file with that name under ".".
9757 * m4sugar/version.m4: Remove; it was included but it wasn't used.
9758 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
9759 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
9760 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
9761 * src/output.c (output_skeleton): Use full path names when
9762 specifying a file to include; don't rely on include path, as
9763 it's unreliable when the working file contains a file with
9766 2002-12-25 Paul Eggert <eggert@twinsun.com>
9768 Remove obsolete references to bison.simple and bison.hairy.
9769 Problem mentioned by Aubin Mahe in
9770 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
9771 * data/glr.c: Comment fix.
9772 * doc/bison.1: Remove references. Also, mention "yacc".
9774 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
9777 * src/parse-gram.y (declaration): Use enum "report_states" rather
9778 than its numeric value 1.
9780 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
9781 opening a new one. This fixes Debian bug 165349, reported by
9784 2002-12-24 Paul Eggert <eggert@twinsun.com>
9788 * Makefile.maint (cvs-update): Don't assume that the shell
9789 supports $(...), as Solaris sh doesn't.
9791 * src/parse-gram.y (lloc_default): Remove test for empty
9792 nonterminals at the end, since it didn't change the result.
9794 2002-12-24 Paul Eggert <eggert@twinsun.com>
9796 If the user does not define YYSTYPE as a macro, Bison now declares it
9797 using typedef instead of defining it as a macro. POSIX requires this.
9798 For consistency, YYLTYPE is also declared instead of defined.
9800 %union directives can now have a tag before the `{', e.g., the
9801 directive `%union foo {...}' now generates the C code
9802 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
9803 The default union tag is `YYSTYPE', for compatibility with Solaris 9
9804 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
9805 instead of `yyltype'.
9807 `yystype' and `yyltype' are now obsolescent macros instead of being
9808 typedefs or tags; they are no longer documented and will be
9809 withdrawn in a future release.
9811 * data/glr.c (b4_location_type): Remove.
9812 (YYSTYPE): Renamed from yystype.
9813 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
9814 (struct YYLTYPE): Renamed from struct yyltype.
9815 (YYLTYPE): Renamed from yyltype.
9816 (yyltype, yystype): New (and obsolescent) macros,
9817 for backward compatibility.
9818 * data/yacc.c: Likewise.
9820 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
9821 does not specify a union tag. This is for compatibility with
9824 * src/parse-gram.y (add_param): 2nd arg is now char * not char
9825 const *, since it is now modified by stripping surrounding { }.
9826 (current_braced_code): Remove.
9827 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
9828 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
9829 trailing " {...}". Now of type <chars>.
9830 (grammar_declaration): Adjust to bundled tokens.
9831 (code_content): Remove; stripping is now done by add_param.
9832 (print_token_value): Print contents of bundled tokens.
9833 (token_name): New function.
9835 * src/reader.h (braced_code, current_braced_code): Remove.
9836 (token_name): New decl.
9838 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
9839 token_type, not braced_code code_kind. All uses changed.
9840 (SC_PRE_CODE): New state, for scanning after a keyword that
9841 has (or usually has) an immediately-following braced code.
9842 (token_type): New local var, to keep track of which token type
9843 to return when scanning braced code.
9844 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
9845 <INITIAL>"%parse-param", <INITIAL>"%printer",
9846 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
9847 instead of returning a token type immediately.
9848 (<INITIAL>"{"): Set token type.
9849 (<SC_BRACED_CODE>"}"): Use it.
9850 (handle_action_dollar, handle_action_at): Now returns bool
9851 indicating success. Fail if ! current_rule; this prevents a core dump.
9852 (handle_symbol_code_dollar, handle_symbol_code_at):
9853 Remove; merge body into caller.
9854 (handle_dollar, handle_at): Complain in invalid contexts.
9856 * NEWS, doc/bison.texinfo: Document the above.
9857 * NEWS: Fix years and program names in copyright notice.
9859 2002-12-17 Paul Eggert <eggert@twinsun.com>
9861 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
9862 Reporting, Table of Symbols): Omit mentions of %lex-param and
9863 %parse-param from the documentation for now.
9865 2002-12-15 Paul Eggert <eggert@twinsun.com>
9867 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
9868 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
9869 lookahead symbol, and which sets yychar in parser actions) and it
9870 disagreed with the Bison documentation. Bug
9871 reported by Andrew Walrond.
9873 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
9874 as the caller now does that.
9875 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
9876 (YYEMPTY): Parenthesize right hand side, since others use it.
9877 (yyparse): Don't assume that our generated code is the only code
9880 2002-12-13 Paul Eggert <eggert@twinsun.com>
9884 POSIX requires a "yacc" command.
9885 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
9886 (MOSTLYCLEANFILES): Add yacc.
9888 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
9889 as an alias for bison y.
9891 * po/LINGUAS: Add da.
9893 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
9894 problem with latest <getopt.h>.
9895 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
9897 * doc/fdl.texi: Upgrade to 1.2.
9898 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
9899 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
9900 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
9902 * config/install-sh: Sync with autotools.
9904 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
9905 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
9906 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
9907 locations are requested.
9908 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
9909 locations are requested.
9911 2002-12-12 Paul Eggert <eggert@twinsun.com>
9913 Remove unportable casts and storage allocation tricks.
9914 While we're at it, remove almost all casts, since they
9915 usually aren't needed and are a sign of trouble.
9917 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
9919 * src/derives.c (derives_compute): Do not subtract NTOKENS from
9920 the pointer DSET returned by malloc; this isn't portable.
9921 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
9922 Similarly for DERIVES.
9923 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
9924 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
9925 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
9927 * src/derives.c (derives_compute): Do not bother invoking
9928 int_of_rule_number, since rule numbers are integers.
9930 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
9931 rather than XMALLOC (char, N).
9933 * src/files.c (filename_split): Rewrite to avoid cast.
9935 * src/gram.h (symbol_number_as_item_number,
9936 item_number_as_symbol_number, rule_number_as_item_number,
9937 item_number_as_rule_number):
9938 Now inline functions rather than macros, to avoid casts.
9939 * src/state.h (state_number_as_int): Likewise.
9940 * src/tables.c (state_number_to_vector_number,
9941 symbol_number_to_vector_number): Likewise.
9943 * src/gram.h (int_of_rule_number): Remove; no longer used.
9945 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
9946 since the resulting storage is always stored into.
9948 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
9951 * src/muscle_tab.c (muscle_m4_output):
9952 Now inline. Return bool, not int.
9953 * src/state.c (state_compare): Likewise.
9954 * src/symtab.c (symbol_check_defined,
9955 symbol_check_alias_consistency, symbol_pack, symbol_translation,
9956 hash_compare_symbol, hash_symbol):
9958 * src/uniqstr.c (uniqstr_print): Likewise.
9959 * src/muscle_tab.c (muscle_m4_output_processor):
9960 New function, to avoid casts.
9961 * src/state.c (state_comparator, stage_hasher): Likewise.
9962 * src/symtab.c (symbol_check_defined_processor,
9963 symbol_check_alias_consistency_processor, symbol_pack_processor,
9964 symbol_translation_processor, hash_symbol_comparator,
9965 hash_symbol_hasher): Likewise.
9966 * src/uniqstr.c (uniqstr_print_processor): Likewise.
9967 * src/muscle_tab.c (muscles_m4_output):
9968 Use new functions instead of casting old functions unportably.
9969 * src/state.c (state_hash_new): Likewise.
9970 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
9971 symbols_token_translations_init):
9973 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
9975 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
9976 var instead of casting to long, to avoid casts.
9977 (prepare_states): Use MALLOC rather than alloca, so that we don't
9978 have to worry about alloca.
9979 * src/state.c (state_hash_lookup): Likewise.
9981 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
9982 local var instead of casting to unsigned char, to avoid casts.
9984 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
9985 STATE_ALLOC): Remove.
9986 (transitions_new, errs_new, reductions_new, state_new): Use malloc
9987 rather than calloc, and use offsetof to avoid allocating slightly
9989 (state_new): Initialize all members.
9991 * src/state.c (state_hash): Use unsigned accumulator, not signed.
9993 * src/symtab.c (symbol_free): Remove; unused.
9994 (symbol_get): Remove cast in lhs of assignment.
9995 (symbols_do): Now static. Accept generic arguments, not
9996 hashing-related ones.
9998 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
9999 (symbol_processor): Remove.
10000 (symbols_do): Remove decl; now static.
10002 * src/system.h (alloca): Remove; decl no longer needed.
10003 (<stddef.h>): Include, for offsetof.
10004 (<inttypes.>, <stdint.h>): Include if available.
10005 (uintptr_t): New type, if system lacks it.
10006 (CALLOC, MALLOC, REALLOC): New macros.
10007 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
10010 * src/tables.c (table_size): Now int, to pacify GCC.

10023 2002-12-09 Paul Eggert <eggert@twinsun.com>
10025 Change identifier spellings to avoid collisions with names
10026 that are reserved by POSIX.
10028 Don't use names ending in _t, since POSIX reserves them.
10029 For consistency, remove _e and _s endings -- they're weren't
10030 needed to remove ambiguity. All uses changed.
10031 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
10032 turn was just renamed from struniq_t.
10033 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
10034 which in turn was just renamed from struniq_processor_t.
10035 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

10106 value_t_as_yystype -> value_as_yystype.
10108 Don't include <errno.h> in the mainstream code, since it
10109 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
10110 * lib/get-errno.c, lib/get-errno.h: New files.
10111 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
10113 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

10121 (TAB_EXT): Renamed from EXT_TAB.
10122 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
10124 Avoid str[a-z]*, since <string.h> reserves that name space.
10125 Change all instances of "struniq" in names to "uniqstr", and
10126 likewise for "STRUNIQ" and "UNIQSTR".
10127 * src/uniqstr.c: Renamed from src/struniq.c.
10128 * src/uniqstr.h: Renamed from src/struniq.h.
10129 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
10130 * src/files.c (strsuffix): Remove; unused.

10139 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
10140 (N_EXPAND): Renamed from N_STRETCH.

10144 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

10151 (BASE_MINIMUM): Renamed from BASE_MIN.
10152 (ACTION_MAX): Remove; unused.
10153 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
10154 Unnecessary casts removed from above defines.
10157 Fix misspelling in names.
10158 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
10159 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
10163 * lib/timevar.c (timevar_report): Renamed from time_report,
10164 for consistency with other names.
10165 * lib/timevar.h (timevar_report): New decl.
10166 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
10169 Sort include-file uses.
10171 Reorder all include files under src to be in the order "system.h".
10172 then the ../lib include files in angle brackets (alphabetized),
10173 then the . include files in double-quotes (alphabetized). Fix
10174 dependency breakages encountered in this process, as follows:
10175 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
10176 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
10177 * src/state.h: Include "symtab.h".
10179 2002-12-08 Paul Eggert <eggert@twinsun.com>
10181 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
10182 since this causes problems when __file__ contains character
10183 sequences like "@" that are treated specially by src/scan-skel.l.
10184 Instead, just use the file's basename. This fixes the bug
10185 reported by Martin Mokrejs in
10186 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
10188 2002-12-06 Paul Eggert <eggert@twinsun.com>
10190 Add support for rules that do not have trailing semicolons, as
10191 POSIX requires. Improve the quality of locations in Bison
10194 * src/location.c: Include <quotearg.h>.
10195 (empty_location): Now const.
10196 (location_print): New function. Follow the recommendation of the
10197 GNU Coding Standards for locations that span file boundaries.
10198 * src/location.h: Do not include <quotearg.h>; no longer needed.
10199 (boundary): New type.
10200 (location_t): Use it. This allows locations to span file boundaries.
10201 All member uses changed: file -> start.file or end.file (as needed),
10202 first_line -> start.line, first_column -> start.column,
10203 last_line -> end.line, last_column -> end.column.
10204 (equal_boundaries): New function.
10205 (LOCATION_RESET, LOCATION_STEP): Remove.
10206 (LOCATION_PRINT): Remove. All callers changed to use location_print.
10207 (empty_location): Now const.
10208 (location_print): New decl.
10209 * src/parse-gram.y (lloc_default): New function, which handles
10210 empty locations more accurately.
10211 (YYLLOC_DEFAULT): Use it.
10212 (%token COLON): Remove.
10213 (%token ID_COLON): New token.
10215 (declarations, rules): Remove trailing semicolon.
10216 (declaration, rules_or_grammar_declaration):
10217 Allow empty (";") declaration.
10218 (symbol_def): Remove empty actions; no longer needed.
10219 (rules_or_grammar_declaration): Remove trailing semicolon.
10220 (semi_colon.opt): Remove.
10221 * src/reader.h: Include location.h.
10222 (scanner_cursor): New decl.
10223 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
10225 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
10227 (STEP): Remove. No longer needed, now that adjust_location does
10228 the work. All uses removed.
10229 (scanner_cursor): New var.
10230 (adjust_location): Renamed from extend_location. It now sets
10231 *loc and adjusts the scanner cursor. All uses changed.
10232 Don't bother testing for CR.
10233 (handle_syncline): Remove location arg; now updates scanner cursor.
10234 All callers changed.
10235 (unexpected_end_of_file): Now accepts start boundary of token or
10236 comment, not location. All callers changed. Update scanner cursor,
10238 (SC_AFTER_IDENTIFIER): New state.
10239 (context_state): Renamed from c_context. All uses changed.
10240 (id_loc, code_start, token_start): New local vars.
10241 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
10242 processing of Yacc white space and equivalents here.
10243 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
10244 instead of returning ID immediately, since we need to search for
10245 a subsequent colon.
10246 (<INITIAL>"'", "\""): Save token_start.
10247 (<INITIAL>"%{", "{", "%%"): Save code_start.
10248 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
10249 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
10250 BEGIN context_state at end, not INITIAL.
10251 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
10252 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
10253 Return correct token start.
10254 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
10255 the start of a character, string or multiline comment is found.
10256 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
10257 Reduction): Adjust reported locations to match the more-precise
10258 results now expected.
10259 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
10260 * tests/reduce.at (Useless Rules, Reduced Automaton,
10261 Underivable Rules): Likewise.
10262 * tests/regression.at (Invalid inputs): No longer `expecting ";"
10263 or "|"' now that so many other tokens are allowed by the new grammar.
10265 * src/complain.h (current_file): Remove duplicate decl;
10266 current_file is now owned by files.h.
10267 * src/complain.c, src/scan-gram.l: Include files.h.
10269 2002-12-06 Paul Eggert <eggert@twinsun.com>
10271 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
10272 promotes to int; it might be unsigned int.
10273 * data/yacc.c (yy_reduce_print): Likewise.
10275 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
10276 be #defined in the prologue, not in the Bison declarations.
10277 This fixes Debian Bug 102878, reported by Shaul Karl.
10279 2002-12-02 Paul Eggert <eggert@twinsun.com>
10281 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
10282 * lib/strtoul.c: New file, from gnulib.
10283 This fixes a porting bug reported by Peter Klein in
10284 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
10286 2002-11-30 Paul Eggert <eggert@twinsun.com>
10288 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
10289 and put only a forward declaration in the prologue. This is for
10290 consistency with the other scanner helper functions.
10292 Type clashes now generate warnings, not errors, since it
10293 appears that POSIX may allow some grammars with type clashes.
10294 * src/reader.c (grammar_current_rule_check): Warn about
10295 type clashes instead of complaining.
10296 * tests/input.at (Type Clashes): Expect warnings, not complaints.
10298 Add Yacc library, since POSIX requires it.
10299 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
10300 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
10301 * lib/main.c, lib/yyerror.c: New files.
10303 gram_error can be static; it need not be extern.
10304 * src/reader.h (gram_error): Remove decl.
10305 * src/parse-gram.y (gram_error): Now static. Add static decl.
10306 (print_token_value): Omit parameter names from forward decl,
10309 2002-11-29 Paul Eggert <eggert@twinsun.com>
10311 * doc/bison.texinfo: Emphasize that yylex and yyerror must
10312 be declared before being used. E.g., one should typically
10313 declare them in the prologue. Use GNU coding style in examples.
10314 Put "const" consistently after the type it modifies. Mention
10315 that C99 supports "inline". Mention that yyerror traditionally
10318 %parse-param and %lex-param now take just one argument, the
10319 declaration; the argument name is deduced from the declaration.
10321 * doc/bison.texinfo (Parser Function, Pure Calling, Error
10322 Reporting, Table of Symbols): Document this.
10323 * src/parse-gram.y (add_param): New function.
10325 (declaration): Implement new rule for %parse-param and %lex-param.
10326 * src/scan-gram.l: "," now elicits a warning, rather than being
10327 a token; this is more compatible with byacc.
10328 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
10330 2002-11-27 Paul Eggert <eggert@twinsun.com>
10332 Rename identifiers to avoid real and potential collisions.
10334 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
10335 to avoid collision with lex macro described by Bruce Lilly in
10336 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10337 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10338 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
10339 * src/parse-gram.y (print_token_value): Renamed from yyprint.
10341 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
10342 The name "yycontrol" violates the name space rules, and this stuff
10343 wasn't being used anyway.
10344 (input): Remove action; this stuff wasn't being used.
10345 (gram_error): Rename local variable yylloc -> loc.
10346 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
10347 (YY_DECL): Don't use "yy" at start of local variables.
10348 All uses changed, e.g., yylloc -> loc.
10349 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
10350 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
10351 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
10352 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
10354 * src/parse-gram.y (gram_error): loc is now const *.
10355 * src/reader.h (gram_error): Likewise.
10357 2002-11-24 Paul Eggert <eggert@twinsun.com>
10361 * tests/actions.at (Actions after errors): Use an output format
10362 more similar to that of the Printers and Destructors test.
10363 Test the position of the ';' token too.
10364 (Printers and Destructors): Likewise.
10365 (Printers and Destructors: %glr-parser): Remove for now, to avoid
10366 unnecessarily alarming people when the test fails.
10368 * data/yacc.c (yyerrlab1): Move this label down, so that the
10369 parser does not discard the lookahead token if the user code
10370 invokes YYERROR. This change is required for POSIX conformance.
10372 * lib/error.c: Sync with gnulib.
10374 2002-11-22 Paul Eggert <eggert@twinsun.com>
10376 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
10377 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
10378 * lib/xmalloc.c: Likewise.
10380 2002-11-20 Paul Eggert <eggert@twinsun.com>
10382 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
10384 2002-11-20 Paul Eggert <eggert@twinsun.com>
10386 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
10387 should use `if (! x) abort ();' rather than `assert (x);', and
10388 anyway it's one less thing to worry about configuring.
10390 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
10391 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
10392 and replace all instances of assert with abort.
10393 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
10394 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
10396 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
10397 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
10398 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
10399 hash_find_entry, hash_rehash, hash_insert): Likewise.
10400 * src/conflicts.c (resolve_sr_conflict): Likewise.
10401 * src/lalr.c (set_goto_map, map_goto): Likewise.
10402 * src/nullable.c (nullable_compute): Likewise.
10403 * src/output.c (prepare_rules, token_definitions_output): Likewise.
10404 * src/reader.c (packgram, reader): Likewise.
10405 * src/state.c (state_new, state_free, state_transitions_set,
10406 state_reduction_find): Likewise.
10407 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
10408 symbol_pack): Likewise.
10409 * src/tables.c (conflict_row, pack_vector): Likewise.
10410 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10411 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10412 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
10413 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
10415 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
10416 (ARGMATCH_CONSTRAINT): New macro.
10417 (ARGMATCH_ASSERT): Use it.
10419 * src/system.h (verify): New macro.
10420 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
10421 rather than assert.
10422 * src/tables.c (tables_generate): Likewise.
10424 * src/struniq.c (struniq_assert): Now returns void, and aborts
10425 if the assertion is false.
10426 (struniq_assert_p): Remove.
10427 * src/struniq.h: Likewise.
10429 2002-11-18 Paul Eggert <eggert@twinsun.com>
10431 * data/glr.c (yygetLRActions): Replace `yyindex' with
10432 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
10433 This fixes the regression with Sun ONE Studio 7 cc that I reported in
10434 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
10436 2002-11-18 Akim Demaille <akim@epita.fr>
10438 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
10440 From Tim Van Holder.
10442 2002-11-17 Paul Eggert <eggert@twinsun.com>
10444 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
10445 to "SyntaxError" for consistency with my 2002-11-15 change.
10447 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
10448 not define to {}, since this breaks the common use of `YYDPRINTF
10449 ((...));' if a single statement is desired (e.g. before `else').
10450 Work around GCC warnings by surrounding corresponding calls with
10452 (yyhasResolvedValue): Remove unused function.
10453 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
10455 (yyreportSyntaxError): Renamed from yyreportParseError.
10456 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
10458 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
10459 extern when possible. Remove unused initializations.
10461 2002-11-16 Akim Demaille <akim@epita.fr>
10463 Augment the similarity between GLR and LALR traces.
10465 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
10466 (YY_REDUCE_PRINT): New.
10467 (yyparse): Use them.
10468 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
10470 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
10471 state reached after the reduction/recovery, since...
10472 (yyparse, yyprocessOneStack): Report the state we are entering in.
10474 2002-11-16 Akim Demaille <akim@epita.fr>
10476 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
10477 Add support for --trace=skeleton.
10478 * src/scan-skel.l: %option debug.
10479 Scan strings of non-@ or \n instead of character by character.
10480 (scan_skel): Handle trace_skeleton.
10482 (@output_parser_name@, @output_header_name@): ``Restore'' their
10483 support (used to be M4 macros).
10484 * data/yacc.c: Quote larger chunks, a la glr.c.
10485 * data/lalr1.cc: Likewise.
10486 The header guards are no longer available, so use some other
10487 string than `YYLSP_NEEDED'.
10489 2002-11-16 Akim Demaille <akim@epita.fr>
10491 Make the ``Printers and Destructors'' test more verbose, taking
10492 `yacc.c''s behavior as (possibly wrong) reference.
10494 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
10495 instead of fprint on stdout.
10496 Set and report the last_line of the symbols.
10497 Consistently display values and locations.
10499 2002-11-16 Paul Eggert <eggert@twinsun.com>
10501 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
10503 2002-11-15 Paul Eggert <eggert@twinsun.com>
10505 * tests/actions.at (Actions after errors): New test case.
10507 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
10508 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
10509 tests/action.at, tests/calc.at, tests/conflicts.at,
10510 tests/cxx-type.at, tests/regression.at:
10511 "parse error" -> "syntax error" for POSIX compatibility.
10512 "parsing stack overflow..." -> "parser stack overflow" so
10513 that code matches Bison documentation.
10515 2002-11-15 Akim Demaille <akim@epita.fr>
10517 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
10518 take two BRACED_CODE, not two string_content.
10519 Free the scanner's obstack when we are done.
10520 (code_content): New.
10521 * tests/calc.at: Adjust.
10522 * doc/bison.texinfo: Adjust.
10523 Also, make sure to include the `,' for these declarations.
10525 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
10527 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
10528 definition; avoids potential autoreconf problems.
10530 2002-11-15 Akim Demaille <akim@epita.fr>
10532 Always check the value returned by yyparse.
10534 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
10535 returned by yyparse.
10536 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
10538 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
10539 returned by yyparse.
10541 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10543 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
10546 2002-11-14 Paul Eggert <eggert@twinsun.com>
10548 * src/output.c (output_skeleton): Call xfopen instead of
10549 duplicating xfopen's body.
10551 Fix bugs reported by Nelson H. F. Beebe in
10552 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
10554 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
10555 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
10556 Group compiler. Instead, use "$CC -E bar.c". Include the .h
10557 file twice in the grammar, as an extra check.
10559 * tests/input.at (Torturing the Scanner): Surround the
10560 backslash-newline tests with "#if 0", to make it less likely that
10561 we'll run into compiler bugs. Bring back solitary \ inside
10562 comment, but add a closing comment to work around HP C bug. Don't
10563 test backslash-newline in C character constant.
10565 2002-11-14 Akim Demaille <akim@epita.fr>
10567 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
10568 status of the compiler.
10569 Calling `exit 1' is no longer needed.
10570 Reported by Nelson H. F. Beebe.
10572 2002-11-14 Akim Demaille <akim@epita.fr>
10574 * tests/atlocal.in (CPPFLAGS): We have config.h.
10575 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
10577 * tests/actions.at, tests/calc.at, tests/conflicts.at,
10578 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
10579 * tests/regression.at, tests/torture.at: Use them for all the
10580 grammars that are to be compiled.
10581 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
10582 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
10583 * doc/bison.texinfo (GLR Parsers): Document `inline'.
10585 2002-11-14 Akim Demaille <akim@epita.fr>
10587 * doc/bison.texinfo: Various formatting changes (alignments in
10588 samples, additional @group/@end group, GCS in samples.
10589 Use @deffn instead of simple @table to define the directives,
10590 macros, variables etc.
10592 2002-11-13 Paul Eggert <eggert@twinsun.com>
10594 Fix some bugs reported by Albert Chin-A-Young in
10595 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
10597 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
10598 -o c"; the HP C compiler chatters during compilation.
10599 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
10600 * tests/headers.at (export YYLTYPE): Likewise.
10602 * tests/input.at (Torturing the Scanner): Remove lines containing
10603 solitary backslashes, as they tickle a bug in the HP C compiler.
10605 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
10606 comments, since they're not portable. Use GNU coding style.
10608 2002-11-13 Akim Demaille <akim@epita.fr>
10610 * data/yacc.c: Leave bigger chunks of quoted text.
10611 (YYDSYMPRINTF): New.
10612 Use it to report symbol activities.
10613 * data/glr.c (YYDSYMPRINTF): New.
10616 2002-11-12 Paul Eggert <eggert@twinsun.com>
10620 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
10621 (yyglrReduce): Return yyok, not 0.
10622 This should avoid the enumerated-type warnings reported
10623 by Nelson H. F. Beebe in
10624 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
10626 * lib/bbitset.h (BITSET_INLINE): Remove.
10627 * lib/bitset.h [! BITSET_INLINE]: Remove.
10628 (bitset_set, bitset_reset, bitset_test): Rename local vars
10629 to avoid shadowing warnings by GCC.
10631 * data/glr.c (inline): Remove #define. It's the user's
10632 responsibility to #define it away, just like 'const'.
10633 This fixes one of the bugs reported by Nelson H. F. Beebe in
10634 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
10636 * Makefile.maint (po-check): Scan .l and .y files instead of the
10637 .c and the .h files that they generate. This fixes the bug
10638 reported by Tim Van Holder in:
10639 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
10640 Look for N_ as well as for _. Try to avoid matching #define for
10642 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
10643 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
10644 * src/scan-gram.l: Revamp regular expressions so that " and '
10645 do not confuse xgettext.
10647 * src/struniq.h (struniq_new): Do not declare the return type
10648 to be 'const'; this violates the C standard.
10649 * src/struniq.c (struniq_new): Likewise.
10651 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
10653 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
10654 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
10657 2002-11-12 Akim Demaille <akim@epita.fr>
10659 * Makefile.maint: Sync with Autoconf:
10660 (local_updates): New.
10662 2002-11-12 Akim Demaille <akim@epita.fr>
10664 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
10666 2002-11-12 Akim Demaille <akim@epita.fr>
10668 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
10671 2002-11-12 Akim Demaille <akim@epita.fr>
10673 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
10676 2002-11-12 Akim Demaille <akim@epita.fr>
10678 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
10679 Use it to test the GLR parser.
10681 2002-11-12 Akim Demaille <akim@epita.fr>
10683 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
10685 * data/glr.c (yystos): New.
10686 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
10687 (YYDSYMPRINT): New.
10688 (yyval): Don't define it, it is handled via M4.
10689 (yyrecoverParseError): Free verbosely the discarded symbols.
10690 * data/yacc.c (yysymprint): Remove, rather...
10691 (b4_yysymprint_generate): invoke.
10692 * data/c.m4 (b4_yysymprint_generate): New.
10693 Accept pointers as arguments, as opposed to the version from
10695 (b4_yydestruct_generate): Likewise.
10696 * tests/cations.at (Printers and Destructors): Use Bison directives
10697 instead of CPP macros.
10698 Don't rely on internal details.
10700 2002-11-12 Akim Demaille <akim@epita.fr>
10702 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
10703 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
10704 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
10705 it against YYEMPTY and so forth), work on yytoken (i.e., set
10706 it to YYEMPTY etc.).
10707 (yydestruct): Replace with a b4_yydestruct_generate invocation.
10708 (b4_symbol_actions): Remove.
10709 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
10710 for 0, end-of-input.
10712 2002-11-12 Akim Demaille <akim@epita.fr>
10714 * doc/bison.texinfo (Destructor Decl): New.
10716 2002-11-12 Akim Demaille <akim@epita.fr>
10718 * src/tables.c (tables_generate): Use free for pointers that
10719 cannot be NULL, not XFREE.
10720 (pack_vector): Use assert, not fatal, for bound violations.
10721 * src/state.c (state_new): Likewise.
10722 * src/reader.c (reader): Likewise.
10723 * src/lalr.c (set_goto_map): Likewise.
10724 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
10727 2002-11-12 Akim Demaille <akim@epita.fr>
10729 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
10731 * src/scan-gram.l (last_string): Is global to the file, not to
10733 * src/parse-gram.y (input): Don't append the epilogue here,
10734 (epilogue.opt): do it here, and free the scanner's obstack.
10735 * src/reader.c (epilogue_set): Rename as...
10736 (epilogue_augment): this.
10737 * data/c.m4 (b4_epilogue): Defaults to empty.
10739 2002-11-12 Akim Demaille <akim@epita.fr>
10741 * src/getargs.c (long_options): Remove duplicates.
10742 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
10744 * doc/bison.rnh: Remove.
10745 * doc/bison.texinfo (VMS Invocation): Remove.
10747 2002-11-12 Akim Demaille <akim@epita.fr>
10749 * src/struniq.h, src/struniq.c (struniq_t): Is const.
10750 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
10752 Use struniq for symbols.
10754 * src/symtab.h (symbol_t): The tag member is a struniq.
10755 (symbol_type_set): Adjust.
10756 * src/symtab.c (symbol_new): Takes a struniq.
10757 (symbol_free): Don't free the tag member.
10758 (hash_compare_symbol_t, hash_symbol_t): Rename as...
10759 (hash_compare_symbol, hash_symbol): these.
10760 Use the fact that tags as struniqs.
10761 (symbol_get): Use struniq_new.
10762 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
10764 * src/reader.h (merger_list, grammar_currentmerge_set): The name
10765 and type members are struniqs.
10766 * src/reader.c (get_merge_function)
10767 (grammar_current_rule_merge_set): Adjust.
10768 (TYPE, current_type): Are struniq.
10770 Use struniq for file names.
10772 * src/files.h, src/files.c (infile): Split into...
10773 (grammar_file, current_file): these.
10774 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.

10776 * src/getargs.c (getargs): Likewise.
10777 * src/complain.h, src/complain.c: Likewise.
10778 * src/main.c (main): Call struniqs_new early enough to use it for
10780 Don't free the input file name.
10782 2002-11-12 Akim Demaille <akim@epita.fr>
10784 * src/symtab.c (symbol_free): Remove dead deactivated code:

10795 2002-11-11 Paul Eggert <eggert@twinsun.com>
10797 Revamp to fix many (but not all) of the C- and M4-related quoting
10798 problems. Among other things, this fixes the Bison bug reported
10799 by Jan Hubicka when processing the Bash grammar; see:
10800 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
10802 Use new @ escapes consistently. Represent brackets with @{ and @}
10803 rather than @<:@ and @:>@, since this works a bit better with dumb
10804 editors like vi. Represent @ with @@, since @ is now consistently
10805 an escape. Use @oline@ and @ofile@ rather than __oline__ and
10806 __ofile__, to avoid unexpected expansions. Similarly, use @output
10807 rather than #output.
10809 * data/c.m4 (b4_copyright): Omit file name from comment, since
10810 the file name could contain "*/".
10811 (b4_synclines_flag): Don't quote the 2nd argument; it should already
10812 be quoted. All uses changed.
10814 * data/glr.c: Use new @ escapes consistently.
10815 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
10816 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
10817 Remove, since they couldn't handle arbitrary characters in file
10819 * data/lalr1.cc: Likewise.
10820 * data/yacc.c: Likewise.
10822 * src/files.c (output_infix): Remove; all uses removed.
10823 * src/files.h: Likewise.
10825 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
10826 mishandled funny characters in file names, and anyway it isn't
10828 * data/yacc.c: Likewise.
10829 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
10831 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
10832 * data/yacc.c: Likewise.
10834 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
10836 (muscle_init): Quote filename as a C string.
10837 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
10838 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
10839 * src/output.c (escaped_file_name_output): New function.
10840 (prepare_symbols): Quote tokens for M4.
10841 (prepare): Don't insert output_infix, output_prefix,
10842 output_parser_name, output_header_name; this is now down by scan-skel.
10843 Insert skeleton as a C string.
10845 * src/output.c (user_actions_output, symbol_destructors_output,
10846 symbol_printers_output): Quote filenames for C and M4.
10847 * src/reader.c (prologue_augment, epilogue_set): Likewise.
10849 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
10850 escapes other than \\ and \'; this simplifies the code.
10851 (<SC_STRING>): Likewise, for \\ and \".
10852 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
10853 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
10854 Use new escapes @{ and @} for [ and ].
10856 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
10857 them with auto vars.
10858 Switch to new escape scheme, where @ is the escape character uniformly.
10859 Abort if a stray escape character is found. Avoid unbounded input
10860 buffer when parsing non-escaped text.
10862 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
10863 __oline__, #output, $@, and @{ do not have unintended meanings.
10865 2002-11-09 Paul Eggert <eggert@twinsun.com>
10867 Fix the test failure due to GCC warnings described in
10868 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
10869 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
10870 evaluate to 0 if it's impossible for NINF to be in the respective
10872 (yygetLRActions, yyrecoverParseError): Use them.
10874 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
10875 counted in the token inserted at end of file. Now takes
10876 location_t *, not location_t, so that the location can be
10877 adjusted. All uses changed.
10879 * tests/regression.at (Invalid inputs): Adjust wording in
10880 diagnostic to match the new behavior.
10882 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
10883 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
10884 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
10885 abort ();'. This reduces the runtime of the "Many lookaheads"
10886 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
10889 2002-11-07 Paul Eggert <eggert@twinsun.com>
10891 * src/parse-gram.y (CHARACTER): Remove unused token.
10894 * src/scan-gram.l: Remove stack option. We no longer use the
10895 stack, since the stack was never deeper than 1; instead, use the
10896 new auto var c_context to record the stacked value.
10898 Remove nounput option. At an unexpected end of file, we now unput
10899 the minimal input necessary to end cleanly; this simplifies the
10902 Avoid unbounded token sizes where this is easy.
10904 (unexpected_end_of_file): New function.
10905 Use it to systematize the error message on unexpected EOF.
10906 (last-string): Now auto, not static.

10910 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
10911 not the (never otherwised-used) CHARACTER.
10913 2002-11-07 Akim Demaille <akim@epita.fr>
10915 Let yyerror always receive the msg as last argument, so that
10916 yyerror can be variadic.
10918 * data/yacc.c (b4_yyerror_args): New.
10919 Use it when calling yyerror.
10920 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

10966 either has GLR conflict entries.
10968 2002-11-05 Paul Eggert <eggert@twinsun.com>
10970 * src/scan-gram.l: Use more accurate diagnostics, e.g.
10971 "integer out of range" rather than "invalid value".
10972 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
10975 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
10976 Also, remove one static variable in the scanner.
10978 * src/scan-gram.l (braces_level): Now auto, not static.
10979 Initialize to zero if the compiler is being picky.
10980 (INITIAL): Clear braces_level instead of incrementing it.
10981 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
10982 as POSIX 1003.1-2001 requires.
10983 * src/system.h (IF_LINT): New macro, taken from coreutils.
10984 * configure.ac: Define "lint" if --enable-gcc-warnings.
10986 2002-11-05 Akim Demaille <akim@epita.fr>
10988 * src/scan-gram.l: When it starts with `%', complain about the
10989 whole directive, not just that `invalid character: %'.
10991 2002-11-04 Akim Demaille <akim@epita.fr>
10993 * Makefile.maint: Update from Autoconf.
10994 (update, cvs-update, po-update, do-po-update): New.

11009 * src/scan-gram.l: Use [\'] instead of ['] to pacify
11012 Use quote, not quote_n since LOCATION_PRINT no longer uses the
11015 2002-11-03 Paul Eggert <eggert@twinsun.com>
11017 * src/reader.c (get_merge_function, grammar_current_rule_check):
11018 Use consistent diagnostics for reporting type name clashes.
11019 Quote the types with <>, for consistency with Yacc.
11020 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
11022 2002-11-03 Akim Demaille <akim@epita.fr>
11024 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
11026 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
11027 (b4_parse_param): Remove.

11029 Propagate b4_pure_args where needed to pass them to yyerror.
11030 * data/glr.m4 (b4_parse_param): Remove.
11031 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

11036 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
11037 (yyreportAmbiguity): When using a pure parser, also need
11038 the location, and the parse-params.
11040 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
11041 When using a pure parser, also need the parse-params.
11043 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
11044 (%pure-parser + %parse-param) LALR and GLR parsers.
11045 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
11046 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

11053 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
11054 (Error Reporting): Adjust to these new directives.
11055 Document %error-verbose, deprecate YYERROR_VERBOSE.
11057 2002-11-03 Akim Demaille <akim@epita.fr>
11059 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
11060 AT_CHECK_CALC_GLR invocations to use % directives, instead of
11061 command line options.
11062 * tests/cxx-type.at: Formatting changes.
11064 2002-11-03 Paul Eggert <eggert@twinsun.com>
11066 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
11067 to count columns correctly, and to check for invalid inputs.
11069 Use mbsnwidth to count columns correctly. Account for tabs, too.
11070 Include mbswidth.h.
11071 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
11072 (extend_location): New function.
11073 (YY_LINES): Remove.
11075 Handle CRLF in C code rather than in Lex code.

11082 Handle backslash-newline correctly in C code.
11083 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
11084 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
11086 (tag, splice): New EREs. Do not allow NUL or newline in tags.
11087 Use {splice} wherever C allows backslash-newline.
11088 YY_STEP after space, newline, vertical-tab.
11089 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
11091 (letter, id): Don't assume ASCII; e.g., spell out a-z.
11093 ({int}, handle_action_dollar, handle_action_at): Check for integer
11096 (YY_STEP): Omit trailing semicolon, so that it's more like C.
11098 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
11099 as well as \000. Check for UCHAR_MAX, not 255.
11100 Allow \x with an arbitrary positive number of digits, as in C.
11101 Check for overflow here.
11102 Allow \? and UCNs, for compatibility with C.
11104 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
11105 with quote slot used by complain_at.
11107 * tests/input.at: Add tests for backslash-newline, m4 quotes
11108 in symbols, long literals, and funny escapes in strings.
11110 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
11111 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
11112 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.

11114 * m4/mbswidth.m4: New file, from GNU coreutils.
11116 * doc/bison.texinfo (Grammar Outline): Document // comments.
11117 (Symbols): Document that trigraphs have no special meaning in Bison,
11118 nor is backslash-newline allowed.
11119 (Actions): Document that trigraphs have no special meaning.

11124 2002-11-02 Paul Eggert <eggert@twinsun.com>
11126 * src/reader.c: Don't include quote.h; not needed.
11127 (get_merge_function): Reword warning to be consistent with
11128 type clash diagnostic in grammar_current_rule_check.
11130 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
11131 bug in trigraph handling.
11133 * src/output.c (prepare_symbols): When printing token names,
11134 escape "[" as "@<:@" and likewise for "]".
11136 * src/system.h (errno): Remove declaration, as we are now
11137 assuming C89 or better, and C89 guarantees errno.
11139 2002-10-30 Paul Eggert <eggert@twinsun.com>
11141 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
11142 Check for close failures.
11143 * src/files.h (xfclose): Return void, not int, since it always
11145 * src/files.c (xfclose): Likewise. Report I/O error if ferror
11147 * src/output.c (output_skeleton): Use xfclose rather than fclose
11148 and ferror. xfclose now checks ferror.
11150 * data/glr.c (YYLEFTMOST_STATE): Remove.
11151 (yyreportTree): Use a stack-based leftmost state. This avoids
11152 our continuing battles with bogus warnings about initializers.
11154 2002-10-30 Akim Demaille <akim@epita.fr>
11156 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
11159 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11161 * tests/glr-regr1.at: New test for reported regressions.
11162 * tests/testsuite.at: Add glr-regr1.at test.

11169 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
11170 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
11171 we use malloc. Don't assume 'A' through 'Z' are contiguous.
11172 Don't assume strdup exists; POSIX says its an XSI extension.
11173 Check for buffer overflow on input.
11175 2002-10-24 Akim Demaille <akim@epita.fr>
11177 * src/output.c (output_skeleton): Don't disable M4sugar comments
11178 too soon: it results in comments being expanded.
11179 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
11182 2002-10-24 Akim Demaille <akim@epita.fr>
11184 * data/yacc.c (m4_int_type): New.
11185 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
11186 char' as only yacc.c wants K&R portability.
11187 * data/glr.c (yysigned_char): Remove.
11188 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
11189 Reported by Quoc Peyrot.
11191 2002-10-23 Paul Eggert <eggert@twinsun.com>
11193 * src/main.c (main): With --trace=time, report times even if a
11194 non-fatal error occurs. Formerly, the times were reported in some
11195 such cases but not in others.
11196 * src/reader.c (reader): Just return if a complaint has been issued,
11197 instead of exiting, so that 'main' can report times.
11199 2002-10-22 Akim Demaille <akim@epita.fr>
11201 * src/system.h: Include sys/types.
11202 Reported by Bert Deknuydt.
11204 2002-10-23 Paul Eggert <eggert@twinsun.com>
11206 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
11207 Suggested by Art Haas.
11209 2002-10-22 Paul Eggert <eggert@twinsun.com>
11211 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
11212 decl; not needed any more.
11213 * src/main.c (main): Use return to exit, undoing yesterday's change.
11214 The last OS that we could find where this wouldn't work is
11215 SunOS 3.5, and that's too old to worry about now.
11217 * data/glr.c (struct yyltype): Define members even when not
11218 doing locations. This is more consistent with yacc.c, and it
11219 works around the following bug reports:
11220 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
11221 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
11223 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
11224 @acronym consistently. Standardize on "Yacc" instead of "YACC",
11225 "Algol" instead of "ALGOL". Give a bit more history about BNF.
11227 2002-10-22 Akim Demaille <akim@epita.fr>
11229 * data/README: New.
11231 2002-10-21 Paul Eggert <eggert@twinsun.com>
11233 Be consistent about 'bool'; the old code used an enum in one
11234 module and an int in another, and this violates the C standard.
11235 * m4/stdbool.m4: New file, from coreutils 4.5.3.
11236 * configure.ac (AC_HEADER_STDBOOL): Add.
11237 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
11238 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
11239 * src/symtab.c (hash_compare_symbol_t): Likewise.
11240 * src/system.h (bool, false, true): Use a definition consistent
11241 with ../lib/hash.c. All uses changed.
11243 * src/complain.c (warning_issued): Renamed from warn_message_count,
11244 so that we needn't worry about integer overflow (!).
11245 Now of type bool. All uses changed.
11246 (complaint_issued): Renamed from complain_message_count; likewise.
11248 * src/main.c (main): Use exit to exit with failure.
11250 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
11251 rather than 1 and 0.
11252 * src/main.c (main): Likewise.
11253 * src/getargs.c (getargs): Likewise.
11254 * src/reader.c (reader): Likewise.
11256 * src/getarg.c (getargs): Remove duplicate code for
11257 "Try `bison --help'".
11259 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
11260 What was that "2" for?
11262 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
11263 * src/getargs.c (usage): Likewise.
11265 * src/getargs.c (getargs): When there are too few operands, report
11266 the last one. When there are too many, report the first extra
11267 one. This is how diffutils does it.
11269 2002-10-20 Paul Eggert <eggert@twinsun.com>
11271 Remove K&R vestiges.
11272 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
11273 * src/complain.c (VA_START): Remove. Assume prototypes.
11274 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
11275 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
11276 fatal): Assume prototypes.
11277 * src/complain.h: Assume prototypes.
11278 * src/system.h (PARAMS): Remove.
11279 Include <limits.h> unconditionally, since it's guaranteeed even
11280 for a freestanding C89 compiler.
11281 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
11282 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
11284 2002-10-20 Akim Demaille <akim@epita.fr>
11286 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
11287 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.

11291 (yy_reduce_print): New.
11292 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
11294 2002-10-20 Akim Demaille <akim@epita.fr>
11296 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
11297 arguments and output `void'.
11298 (b4_c_function): Rename as...
11299 (b4_c_function_def): this.
11300 (b4_c_function_decl, b4_c_ansi_function_def)
11301 (b4_c_ansi_function_decl): New.
11302 Change the interpretation of the arguments: before `int, foo', now
11304 * data/yacc.c (yyparse): Prototype and define thanks to these.
11305 Adjust b4_c_function_def uses.
11306 * data/glr.c (yyparse): Likewise, but ANSI only.
11308 2002-10-20 Akim Demaille <akim@epita.fr>
11310 * src/output.c (prepare): Move the definition of `tokens_number',
11311 `nterms_number', `undef_token_number', `user_token_number_max'
11313 (prepare_tokens): Here.
11314 (prepare_tokens): Rename as...
11315 (prepare_symbols): this.
11316 (prepare): Move the definition of `rules_number' to...
11317 (prepare_rules): here.
11318 (prepare): Move the definition of `last', `final_state_number',
11319 `states_number' to...
11320 (prepare_states): here.
11321 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
11323 2002-10-20 Akim Demaille <akim@epita.fr>
11325 * src/tables.h, src/tables.c, src/output.c: Comment changes.
11327 2002-10-20 Akim Demaille <akim@epita.fr>
11329 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
11332 2002-10-20 Akim Demaille <akim@epita.fr>
11334 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
11335 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
11337 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
11339 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
11340 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
11343 2002-10-19 Paul Eggert <eggert@twinsun.com>
11345 Do not create a temporary file, as that involves security and
11346 cleanup headaches. Instead, use a pair of pipes.
11347 Derived from a suggestion by Florian Krohm.
11348 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
11349 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
11350 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
11351 (BISON_PREREQ_SUBPIPE): Add.
11352 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
11353 Add subpipe.h, subpipe.c.
11354 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
11355 * po/POTFILES.in: Add lib/subpipe.c.
11356 * src/output.c: Include "subpipe.h".
11357 (m4_invoke): Remove decl.
11358 (scan_skel): New decl.
11359 (output_skeleton): Use pipe rather than temporary file for m4 input.
11360 Check that m4sugar.m4 is readable, to avoid deadlock.
11361 Check for pipe I/O error.
11362 * src/scan-skel.l (readpipe): Remove decl.
11363 (scan_skel): New function, to be used in place of m4_invoke.
11364 Read from stream rather than file.
11366 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
11367 float, as this generates a warning on Solaris 8 + GCC 3.2 with
11368 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
11369 this generates a more-accurate value anyway.
11371 * lib/timevar.c (timervar_accumulate): Rename locals to
11372 avoid confusion with similarly-named more-global.
11373 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
11375 * src/output.c (prepare): Use xstrdup to convert char const *
11376 to char *, to avoid GCC warning.
11378 2002-10-19 Akim Demaille <akim@epita.fr>
11380 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
11381 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
11382 Use them to have `calc.y' ready for %pure-parser.
11383 * data/yacc.c (YYLEX): Pass a yylex return type to
11384 b4_c_function_call.
11386 2002-10-19 Akim Demaille <akim@epita.fr>
11388 Prototype support of %lex-param and %parse-param.
11390 * src/parse-gram.y: Add the definition of the %lex-param and
11391 %parse-param tokens, plus their rules.
11392 Drop the `_' version of %glr-parser.
11394 * src/scan-gram.l (INITIAL): Scan them.
11395 * src/muscle_tab.c: Comment changes.
11396 (muscle_insert, muscle_find): Rename `pair' as `probe'.
11397 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
11398 (muscle_entry_s): The `value' member is no longer const.
11399 Adjust all dependencies.
11400 * src/muscle_tab.c (muscle_init): Adjust: use
11401 MUSCLE_INSERT_STRING.
11402 Initialize the obstack earlier.
11403 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
11404 (muscle_pair_list_grow): New.
11405 * data/c.m4 (b4_c_function_call, b4_c_args): New.
11406 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
11407 * tests/calc.at: Use %locations, not --locations.
11408 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
11410 2002-10-19 Akim Demaille <akim@epita.fr>
11412 * src/getargs.c (usage): Take status as argument and exit
11414 Report the traditional `Try ... --help' message when status != 0.
11415 (usage, version): Don't take a FILE * as arg, it is pointless.
11416 (getargs): When there is an incorrect number of arguments, make it
11417 an error, and report it GNUlically thanks to `usage ()'.
11419 2002-10-18 Paul Eggert <eggert@twinsun.com>
11421 * data/glr.c (yyreportParseError): Don't assume that sprintf
11422 yields the length of the printed string, as this is not true
11423 on SunOS 4.1.4. Reported by Peter Klein.
11425 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
11426 * tests/conflicts.at (%nonassoc and eof): Likewise.
11427 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
11429 2002-10-17 Akim Demaille <akim@epita.fr>
11431 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
11432 * src/getargs.c (trace_types, trace_args): Adjust.
11433 * src/reader.c (grammar_current_rule_prec_set)
11434 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
11435 Standardize error messages.
11436 And s/@prec/%prec/!
11437 (reader): Use trace_flag to enable scanner/parser debugging,
11438 instead of an adhoc scheme.
11439 * src/scan-gram.l: Remove trailing debugging code.
11441 2002-10-16 Paul Eggert <eggert@twinsun.com>
11443 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
11446 * NEWS: Officially drop support for building Bison with K&R C,
11447 since it didn't work anyway and it's not worth worrying about.
11448 * Makefile.maint (wget_files): Remove ansi2knr.c.
11449 (ansi2knr.c-url_prefix): Remove.
11450 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
11451 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11452 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11454 2002-10-15 Paul Eggert <eggert@twinsun.com>
11456 Stop using the "enum_" trick for K&R-style function definitions;
11457 it confused me, and I was the author! Instead, assume that people
11458 who want to use K&R C compilers (when using these modules in GCC,
11459 perhaps?) will run ansi2knr.
11461 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
11462 All uses of "enum_" changed to "enum ".
11463 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
11464 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
11466 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

11474 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
11475 Use function prototypes; this removes the need for declaring
11476 static functions simply to provide their prototypes.
11477 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

11538 2002-10-14 Akim Demaille <akim@epita.fr>
11540 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
11543 2002-10-14 Akim Demaille <akim@epita.fr>
11545 * src/tables.c (table_ninf_remap): base -> tab.
11546 Reported by Matt Rosing.
11548 2002-10-14 Paul Eggert <eggert@twinsun.com>
11550 * tests/action.at, tests/calc.at, tests/conflicts.at,
11551 tests/cxx-type.at, tests/headers.at, tests/input.at,
11552 tests/regression.at, tests/synclines.at, tests/torture.at:
11553 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
11554 so that the tests still work even if POSIXLY_CORRECT is set.
11555 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
11557 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
11558 for portability to K&R hosts. Fix typo: signed char is guaranteed
11559 only to 127, not to 128.
11560 * data/glr.c (yysigned_char): New type.
11561 * data/yacc.c (yysigned_char): Likewise.
11562 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
11564 2002-10-13 Paul Eggert <eggert@twinsun.com>
11566 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
11567 true due to limited range of data type" warning from GCC.
11569 * data/c.m4 (b4_token_defines): Protect against double-inclusion
11570 by wrapping enum yytokentype's definition inside #ifndef
11571 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
11573 2002-10-13 Akim Demaille <akim@epita.fr>
11575 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
11576 Un yy- yyrhs to avoid the name clash with the global YYRHS.
11578 2002-10-13 Akim Demaille <akim@epita.fr>
11580 * Makefile.maint: Update from Autoconf 2.54.
11581 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
11583 2002-10-13 Akim Demaille <akim@epita.fr>
11585 * src/print.c (print_state): Separate the list of solved conflicts
11586 from the other items.
11587 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
11589 2002-10-13 Akim Demaille <akim@epita.fr>
11591 Let nondeterministic skeletons be usable with deterministic
11594 With the patch, GAWK compiled by GCC without -O2 passes its test
11595 suite using a GLR parser driven by LALR tables. It fails with -O2
11596 because `struct stat' gives two different answers on my machine:
11597 88 (definition of an auto var) and later 96 (memset on this var).
11598 Hence the stack is badly corrumpted. The headers inclusion is to
11599 blame: if I move the awk.h inclusion before GLR's system header
11600 inclusion, the two struct stat have the same size.
11602 * src/tables.c (pack_table): Always create conflict_table.
11603 (token_actions): Always create conflict_list.
11604 * data/glr.c (YYFLAG): Remove, unused.
11606 2002-10-13 Akim Demaille <akim@epita.fr>
11608 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
11610 (VALGRIND, GXX): New.
11611 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
11612 * tests/bison.in: Run $PREBISON a pre-command.
11613 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
11614 (maintainer-check-g++): New.
11615 * Makefile.am (maintainer-check): New.
11617 2002-10-13 Akim Demaille <akim@epita.fr>
11619 * data/glr.c: Formatting changes.
11620 Tweak some trace messages to match yacc.c's.
11622 2002-10-13 Akim Demaille <akim@epita.fr>
11624 GLR parsers sometimes raise parse errors instead of performing the
11626 Reported by Charles-Henry de Boysson.
11628 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
11629 check the length of the traces when %glr.
11630 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
11632 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
11634 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
11635 (yyltype): Remove the yy prefix from the member names.
11636 (yytable): Complete its comment.
11637 (yygetLRActions): Map error action number from YYTABLE from
11639 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
11640 (which was a bug: it should have been YYTABEL_NINF, and yet it was
11641 not satisfying as we could compare an YYACTION computed from
11642 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
11643 only value for error actions.
11644 (yyreportParseError): In verbose parse error messages, don't issue
11645 `error' in the list of expected tokens.
11646 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
11647 next action to perform to match glr.c's decoding.
11648 (yytable): Complete its comment.
11650 2002-10-13 Paul Eggert <eggert@twinsun.com>
11652 Fix problem reported by Henrik Grubbstroem in
11653 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
11654 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
11655 because the Bison parser reads the second action before reducing
11657 * src/scan-gram.l (rule_length): New static var.
11658 Use it to keep track of the rule length in the scanner, since
11659 we can't expect the parser to be in lock-step sync with the scanner.
11660 (handle_action_dollar, handle_action_at): Use this var.
11661 * tests/actions.at (Exotic Dollars): Test for the problem.
11663 2002-10-12 Paul Eggert <eggert@twinsun.com>
11665 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
11666 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
11667 Include <sys/time.h> when checking for clock_t and struct tms.
11668 Use same include order as source.
11669 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
11670 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
11672 * lib/timevar.c: Update copyright date and clarify comments.
11673 (get_time) [IN_GCC]: Keep the GCC version for reference.
11675 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
11676 GCC version as of today, then merge Bison's changes.
11677 Change "GCC" to "Bison" in copyright notice. timevar.def's
11678 author is Akim, so change that too.
11680 * src/reader.c (grammar_current_rule_check):
11681 Don't worry about the default action if $$ is untyped.
11682 Prevents bogus warnings reported by Jim Gifford in
11683 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
11685 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
11686 * data/glr.c, data/lalr1.cc, data/yacc.c:
11687 Output token definitions before the first part of user declarations.
11688 Fixes compatibility problem reported by Jim Gifford for kbd in
11689 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
11691 2002-10-11 Paul Eggert <eggert@twinsun.com>
11693 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
11694 (yyparse): here. This undoes some of the 2002-07-25 change.
11695 Compatibility problem reported by Ralf S. Engelschall with
11696 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

11715 * lib/lbitset.c: Likewise.
11717 * lib/abitset.c (abitset_bytes): Return a size that is aligned
11718 properly for vectors of objects. Do not assume that adding a

11720 properly aligned for the whole union.

11761 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
11763 Do not use "struct bitset_struct" to mean different things in
11764 different modules. Not only is this confusing, it violates
11765 the C Standard, which requires that structure types in different
11766 modules must be compatible if one is to be passed to the other.
11767 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
11768 All instances of "struct bitset_struct *" replaced with "bitset".

11812 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
11813 the same width as int. This reapplies a hunk of the 2002-08-12 patch
11814 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
11815 which was inadvertently undone by the 2002-09-30 patch.

11817 the same width as int.

12119 PROTOTYPES to check for prototypes, and "defined __STDC__" to

12125 (bitset_test): Now returns int, not unsigned long.

12168 * src/main.c (main): Cast result of bindtextdomain and textdomain
12169 to void, to avoid a GCC warning when --disable-nls is in effect.
12171 * src/scan-gram.l: Use strings rather than escapes when possible,
12172 to minimize the number of warnings from xgettext.
12173 (handle_action_dollar, handle_action_at): Don't use isdigit,
12174 as it mishandles negative chars and it may not work as expected
12175 outside the C locale.
12177 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
12178 this is a GCC extension and is not portable to other compilers.

12417 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
12418 for the time being: %locations ought to provide it to yyerror.

12422 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

14124 Add an invocation exercising the error token.
14125 Add an invocation demonstrating a stupid error message.
14126 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

14391 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
14392 lacking `+ 1' to nrules, Bison reported as useless a token if it
14393 was used solely to set the precedence of the last rule...
14395 2002-04-07 Akim Demaille <akim@epita.fr>
14397 * data/bison.c++, data/bison.simple: Don't output the current file
14398 name in #line, to avoid useless diffs between two identical
14399 outputs under different names.

14403 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

14420 RHS, instead of being an index in RITEMS.

14607 2002-03-04 Akim Demaille <akim@epita.fr>
14609 * src/conflicts.c (shiftset, lookaheadset): Now bitset.
14610 Adjust all dependencies.
14612 2002-03-04 Akim Demaille <akim@epita.fr>
14614 * src/L0.c, src/LR0.h (nstates): Be size_t.
14615 Adjust comparisons (signed vs unsigned).
14616 * src/conflics.c, src/lalr.c, src/lalr.h, src/output.c (LA): Now a

14623 Adjust all dependencies.
14624 (varsetsize): Remove, now unused.

14627 2002-03-04 Akim Demaille <akim@epita.fr>
14629 * src/print.c: Convert to use bitset.h, not hand coded iterations
14632 2002-03-04 Akim Demaille <akim@epita.fr>
14634 * src/reduce.c: Convert to use bitset.h, not hand coded BSet.
14636 2002-03-04 Akim Demaille <akim@epita.fr>
14638 * src/closure.c (ruleset): Be a bitset.
14639 (rulesetsize): Remove.
14641 2002-03-04 Akim Demaille <akim@epita.fr>

14648 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
14650 * data/bison.c++: Merge the two generated headers. Insert a copyright
14651 notice in each output file.
14653 2002-02-28 Akim Demaille <akim@epita.fr>
14655 * data/bison.c++: Copy the prologue of bison.simple to fetch
14656 useful M4 definitions, such as b4_header_guard.
14658 2002-02-25 Akim Demaille <akim@epita.fr>
14660 * src/getargs.c (version): Give the name of the authors, and use a
14661 translator friendly scheme for the bgr
14664 2002-02-25 Akim Demaille <akim@epita.fr>
14666 * src/output.c (header_output): Remove, now handled completely via
14669 2002-02-25 Akim Demaille <akim@epita.fr>
14671 * m4/m4.m4: New, from CVS Autoconf.
14672 * configure.in: Invoke it.
14673 * src/output.c (output_skeleton): Use its result instead of the
14676 2002-02-25 Akim Demaille <akim@epita.fr>
14678 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
14680 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
14681 * src/output.c (output_skeleton): Use mkstemp to create a real
14683 Move the filling of `skeleton' and its muscle to...
14685 (output): Move the definition of the prologue muscle to...
14687 * src/system.h (DEFAULT_TMPDIR): New.
14689 2002-02-14 Paul Eggert <eggert@twinsun.com>
14691 Remove the support for C++ namespace cleanliness; it was
14692 causing more problems than it was curing, since it didn't work
14693 properly on some nonstandard C++ compilers. This can wait
14694 for a proper C++ parser.
14696 * NEWS: Document this.
14697 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
14698 of C++, as it's treated like C now.
14699 * src/bison.simple (YYSTD): Remove.
14700 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
14701 Treat C++ just like Standard C instead of trying to support
14702 namespace cleanliness.
14704 2002-02-14 Akim Demaille <akim@epita.fr>
14706 * tests/regression.at (else): Adjust to Andreas' change.
14708 2002-02-14 Akim Demaille <akim@epita.fr>
14710 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
14712 2002-02-13 Andreas Schwab <schwab@suse.de>
14714 * src/output.c (output_rule_data): Don't output NULL, it might
14715 not be defined yet.
14717 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
14719 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
14720 (Copyright notice): Update.
14722 2002-02-11 Akim Demaille <akim@epita.fr>
14724 * tests/regression.at (%nonassoc and eof): Don't include
14725 nonportable headers.
14727 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
14729 * data/bison.c++: Correct error recovery. Make the user able to
14730 initialize the starting location.
14732 2002-02-07 Akim Demaille <akim@epita.fr>
14734 * tests/input.at: New.
14736 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14738 * data/bison.c++: Replace some direct m4 expansions by constants. Be
14739 more consistent when naming methods and variables. Put preprocessor
14740 directives around tables only needed for debugging.
14742 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14744 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
14746 (yy::b4_name::parse): Use print_.
14748 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14750 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
14752 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14754 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
14756 (yy::b4_name::parse): Build verbose error messages, and use error_.
14758 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
14760 * data/bison.c++: Fix m4 quoting in comments.
14762 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
14764 * data/bison.c++: Adjust the parser code. Fix some muscles that were
14765 not expanded by m4.
14767 2002-02-05 Akim Demaille <akim@epita.fr>
14769 * data/bison.c++: Adjust to the M4 back end.
14770 More is certainly needed.
14772 2002-02-05 Akim Demaille <akim@epita.fr>
14774 Give a try to M4 as a back end.
14776 * lib/readpipe.c: New, from wdiff.
14777 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
14779 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
14780 specific values. Now it is m4 that performs the lookup.
14781 * src/parse-skel.y: Remove.
14782 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
14783 * src/output.c (actions_output, guards_output)
14784 (token_definitions_output): No longer keeps track of the output
14785 line number, hence remove the second argument.
14786 (guards_output): Check against the guard member of a rule, not the
14789 (output_skeleton): Don't look for the skeleton location, let m4 do
14791 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
14793 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
14794 (prepare): Given that for the time being changesyntax is not
14795 usable in M4, rename the muscles using `-' to `_'.
14796 Define `defines_flag', `output_parser_name' and `output_header_name'.
14797 * src/output.h (actions_output, guards_output)
14798 (token_definitions_output): Adjust prototypes.
14799 * src/scan-skel.l: Instead of scanning the skeletons, it now
14800 processes the output of m4: `__oline__' and `#output'.
14801 * data/bison.simple: Adjust to be used by M4(sugar).
14802 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
14804 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
14805 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
14806 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
14807 shamelessly stolen from CVS Autoconf.
14809 2002-02-05 Akim Demaille <akim@epita.fr>
14811 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
14812 * configure.in: Check for the declarations of free and malloc.
14813 * src/muscle_tab.c: Adjust.
14815 2002-02-05 Akim Demaille <akim@epita.fr>
14817 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
14818 which have no values.
14820 2002-02-05 Akim Demaille <akim@epita.fr>
14822 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
14825 2002-01-29 Paul Eggert <eggert@twinsun.com>
14827 * src/bison.simple (YYSIZE_T): Do not define merely because
14828 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
14829 On some platforms, <alloca.h> does not declare YYSTD (size_t).
14831 2002-01-27 Akim Demaille <akim@epita.fr>
14833 Fix `%nonassoc and eof'.
14835 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
14836 which were not properly copied! Replace
14837 memcpy (res->errs, src->errs, src->nerrs);
14839 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
14841 * tests/regression.at (%nonassoc and eof): Adjust to newest
14842 Autotest: `.' is not in the PATH.
14844 2002-01-27 Akim Demaille <akim@epita.fr>
14846 * tests/sets.at (AT_EXTRACT_SETS): New.
14847 (Nullable): Use it.
14850 2002-01-26 Akim Demaille <akim@epita.fr>
14852 * tests/actions.at, tests/calc.at, tests/headers.at,
14853 * tests/torture.at: Adjust to the newest Autotest which no longer
14854 forces `.' in the PATH.
14856 2002-01-25 Akim Demaille <akim@epita.fr>
14858 * tests/regression.at (%nonassoc and eof): New.
14859 Suggested by Robert Anisko.
14861 2002-01-24 Akim Demaille <akim@epita.fr>
14863 Bison dumps core when trying to complain about broken input files.
14864 Reported by Cris van Pelt.
14866 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
14867 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
14869 (Invalid inputs): Strengthen: exercise parse_percent_token.
14871 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
14873 * src/Makefile.am: Add bison.c++.
14874 * src/bison.c++: New skeleton.
14876 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
14880 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
14882 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
14884 2002-01-20 Marc Autret <marc@gnu.org>
14886 * src/files.c (compute_output_file_names): Fix
14888 2002-01-20 Marc Autret <marc@gnu.org>
14890 * tests/output.at: New test.
14891 * src/files.c (compute_base_names): Don't map extensions when
14892 the YACC flag is set, use defaults.
14893 Reported by Evgeny Stambulchik.
14895 2002-01-20 Marc Autret <marc@gnu.org>
14897 * src/system.h: Need to define __attribute__ away for non-GCC
14898 compilers as well (i.e., the vendor C compiler).
14899 Suggested by Albert Chin-A-Young.
14901 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
14903 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
14904 canonical definition.
14905 * src/system.h: Use the canonical definition for PARAMS (avoids
14906 a conflict with the macro from lib/hash.h).
14908 2002-01-11 Akim Demaille <akim@epita.fr>
14910 * configure.in: Use AC_FUNC_STRNLEN.
14911 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
14913 2002-01-09 Akim Demaille <akim@epita.fr>
14915 * src/files.c, src/files.h (output_infix): New.
14916 (tab_extension): Remove.
14917 (compute_base_names): Compute the former, drop the latter.
14918 * src/output.c (prepare): Insert the muscles `output-infix', and
14920 * src/parse-skel.y (string, string.1): New.
14921 (section.header): Use it.
14922 (section.yacc): Remove.
14923 (prefix): Remove too.
14924 * src/scan-skel.l: Adjust.
14925 * src/bison.simple, src/bison.hairy: Adjust.
14927 2002-01-09 Akim Demaille <akim@epita.fr>
14929 * configure.in (WERROR_CFLAGS): Compute it.
14930 * src/Makefile.am (CFLAGS): Pass it.
14931 * tests/atlocal.in (CFLAGS): Idem.
14932 * src/files.c: Fix a few warnings.
14933 (get_extension_index): Remove, unused.
14935 2002-01-08 Akim Demaille <akim@epita.fr>
14937 * src/getargs.c (AS_FILE_NAME): New.
14938 (getargs): Use it to convert DOSish file names.
14939 * src/files.c (base_name): Rename as full_base_name to avoid
14940 clashes with `base_name ()'.
14941 (filename_split): New.
14942 (compute_base_names): N-th rewrite, using filename_split.
14944 2002-01-08 Akim Demaille <akim@epita.fr>
14946 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
14947 New, stolen from the Fileutils 4.1.
14948 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
14949 * configure.in: Check for the presence of memrchr, and of its
14952 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
14954 * lib/hash.h (__P): Added definition for this macro.
14955 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
14956 BUILT_SOURCES, to ensure they are generated first.
14957 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
14958 %error-verbose to allow bootstrapping with bison 1.30x.
14960 2002-01-06 Akim Demaille <akim@epita.fr>
14962 * src/reader.c (parse_braces): Don't fetch the next char, the
14963 convention is to fetch on entry.
14964 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
14965 'switch' without a following semicolon.
14966 * tests/regression.at (braces parsing): New.
14968 2002-01-06 Akim Demaille <akim@epita.fr>
14970 Bison is dead wrong in its RR conflict reports.
14972 * tests/torture.at (GNU Cim Grammar): New.
14973 * src/conflicts.c (count_rr_conflicts): Fix.
14975 2002-01-06 Akim Demaille <akim@epita.fr>
14977 Creating package.m4 from configure.ac causes too many problems.
14979 * tests/Makefile.am (package.m4): Create it by hand,
14980 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
14982 2002-01-06 Akim Demaille <akim@epita.fr>
14984 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
14987 2002-01-04 Paul Eggert <eggert@twinsun.com>
14989 * doc/bison.texinfo (Debugging):
14990 Remove YYSTDERR; it's no longer defined or used.
14991 Also, s/cstdio.h/cstdio/.
14993 2002-01-03 Akim Demaille <akim@epita.fr>
14995 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
14997 2002-01-03 Akim Demaille <akim@epita.fr>
14999 * src/parse-skel.y (process_skeleton): Don't bind the parser's
15000 tracing code to --trace, wait for a better --trace option, with
15003 2002-01-03 Akim Demaille <akim@epita.fr>
15005 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
15006 The ISO C++ standard is extremely clear about it: stderr is
15007 considered a macro, not a regular symbol (see table 94 `Header
15008 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
15009 Therefore std:: does not apply to it. It still does with fprintf.
15010 Also, s/cstdio.h/cstdio/.
15012 2002-01-03 Akim Demaille <akim@epita.fr>
15014 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
15015 for non system headers.
15017 2002-01-02 Akim Demaille <akim@epita.fr>
15019 Equip the skeleton chain with location tracking, runtime trace,
15020 pure parser and scanner.
15022 * src/parse-skel.y: Request a pure parser, locations, and prefix
15024 (%union): Having several members with the same type does not help
15025 type mismatches, simplify.
15026 (YYPRINT, yyprint): New.
15027 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
15028 (skel_error): this.
15030 * src/scan-skel.l: Adjust to these changes.
15031 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
15032 (LOCATION_PRINT, skel_control_t): New.
15034 2001-12-30 Akim Demaille <akim@epita.fr>
15036 * src/parse-skel.y: Get rid of the shift/reduce conflict:
15037 replace `gb' with BLANKS.
15038 * src/scan-skel.l: Adjust.
15040 2001-12-30 Akim Demaille <akim@epita.fr>
15042 * src/system.h: We don't need nor want bcopy.
15043 Throw away MS-DOS crap: we don't need getpid.
15044 * configure.in: We don't need strndup. It was even causing
15045 problems: because Flex includes the headers *before* us,
15046 _GNU_SOURCE is not defined by config.h, and therefore strndup was
15048 * lib/xstrndup.c: New.
15049 * src/scan-skel.l: Use it.
15050 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
15051 * src/parse-skel.y: Use %directives instead of #defines.
15053 2001-12-30 Akim Demaille <akim@epita.fr>
15055 * src/skeleton.h: New.
15056 * src/output.c (output_parser, output_master_parser): Remove, dead
15058 * src/output.h (get_lines_number, actions_output, guards_output)
15059 (token_definitions_output): Prototype them.
15060 * src/parse-skel.y: Add the license notice.
15061 Include output.h and skeleton.h.
15062 (process_skeleton): Returns void, and takes a single parameter.
15063 * src/scan-skel.l: Add the license notice.
15064 Include skeleton.h.
15065 Don't use %option yylineno: it seems that then Flex imagines
15066 REJECT has been used, and therefore it won't reallocate its
15067 buffers (which makes no other sense to me than a bug). It results
15068 in warnings for `unused: yy_flex_realloc'.
15070 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
15072 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15073 (MUSCLE_INSERT_PREFIX): ...to there.
15074 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15075 (MUSCLE_INSERT_PREFIX): Move from here...
15077 * src/bison.hairy: Add a section directive. Put braces around muscle
15078 names. This parser skeleton is still broken, but Bison should not
15079 choke on a bad muscle 'syntax'.
15080 * src/bison.simple: Add a section directive. Put braces around muscle
15083 * src/files.h (strsuffix, stringappend): Add declarations.
15084 (tab_extension): Add declaration.
15085 (short_base_name): Add declaration.
15087 * src/files.c (strsuffix, stringappend): No longer static. These
15088 functions are used in the skeleton parser.
15089 (tab_extension): New.
15090 (compute_base_names): Use the computations done in this function
15091 to guess if the generated parsers should have '.tab' in their
15093 (short_base_name): No longer static.
15095 * src/output.c (output_skeleton): New.
15096 (output): Disable call to output_master_parser, and give a try to
15097 a new skeleton handling system.
15098 (guards_output, actions_output): No longer static.
15099 (token_definitions_output, get_lines_number): No longer static.
15101 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
15103 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
15106 * src/parse-skel.y: New file.
15107 * src/scan-skel.l: New file.
15109 2001-12-29 Akim Demaille <akim@epita.fr>
15111 %name-prefix is broken.
15113 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
15114 Adjust all dependencies.
15115 * tests/headers.at (export YYLTYPE): Strengthen this test: use
15118 Renaming yylval but not yylloc is not consistent. Now we do.
15120 * src/bison.simple: Prefix yylloc if used.
15121 * doc/bison.texinfo (Decl Summary): Document that.
15123 2001-12-29 Akim Demaille <akim@epita.fr>
15125 * doc/bison.texinfo: Promote `%long-directive' over
15127 Remove all references to fixed-output-files, yacc is enough.
15129 2001-12-29 Akim Demaille <akim@epita.fr>
15131 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
15132 user prologue. These are defaults.
15133 * tests/actions.at (Mid-rule actions): Make sure the user can
15134 define YYDEBUG and YYERROR_VERBOSE.
15136 2001-12-29 Akim Demaille <akim@epita.fr>
15138 * src/output.c (header_output): Don't forget to export YYLTYPE and
15140 * tests/headers.at (export YYLTYPE): New, make sure it does.
15141 * tests/regression.at (%union and --defines, Invalid CPP headers):
15143 * tests/headers.at: here.
15145 2001-12-29 Akim Demaille <akim@epita.fr>
15147 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
15149 2001-12-29 Akim Demaille <akim@epita.fr>
15151 * tests/actions.at (Mid-rule actions): Output on a single line
15152 instead of several.
15154 2001-12-29 Akim Demaille <akim@epita.fr>
15156 * doc/bison.texinfo: Formatting changes.
15158 2001-12-29 Akim Demaille <akim@epita.fr>
15160 Don't store the token defs in a muscle, just be ready to output it
15161 on command. Now possible via `symbols'. Fixes a memory leak.
15163 * src/output.c (token_definitions_output): New.
15164 (output_parser, header_output): Use it.
15165 * src/reader.c (symbols_save): Remove.
15167 2001-12-29 Akim Demaille <akim@epita.fr>
15169 * src/bison.simple: Do not provide a default for YYSTYPE and
15170 YYLTYPE before the user's prologue. Otherwise it's hardly... a
15173 2001-12-29 Akim Demaille <akim@epita.fr>
15175 Mid-rule actions are simply... ignored!
15177 * src/reader.c (readgram): Be sure to attach mid-rule actions to
15178 the empty-rule associated to the dummy symbol, not to the host
15180 * tests/actions.at (Mid-rule actions): New.
15182 2001-12-29 Akim Demaille <akim@epita.fr>
15186 * src/reader.c (reader): Free grammar.
15188 2001-12-29 Akim Demaille <akim@epita.fr>
15192 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
15193 since it allocates it for each state, although only one is needed.
15194 (allocate_storage): Do it here.
15196 2001-12-29 Akim Demaille <akim@epita.fr>
15198 * src/options.h, src/options.c (create_long_option_table): Rename
15200 (long_option_table_new): this, with a clearer prototype.
15201 (percent_table): Remove, unused,
15202 * src/getargs.c (getargs): Adjust.
15204 2001-12-29 Akim Demaille <akim@epita.fr>
15206 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
15207 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
15210 2001-12-29 Akim Demaille <akim@epita.fr>
15212 * src/lalr.c (build_relations): Rename `states' as `states1'.
15213 Sorry, I don't understand exactly what it is, no better name...
15215 2001-12-29 Akim Demaille <akim@epita.fr>
15217 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
15218 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

15227 2001-12-29 Akim Demaille <akim@epita.fr>
15229 * src/reader.c, src/reader.h (user_toknums): Remove.
15230 Adjust all users to use symbols[i]->user_token_number.

15234 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
15235 Adjust all users to use symbols[i]->prec or ->assoc.

15239 * src/reader.c, src/reader.h (tags): Remove.
15240 Adjust all users to use symbols[i]->tag.
15242 2001-12-29 Akim Demaille <akim@epita.fr>
15244 * src/gram.h, src/gram.c (symbols): New, similar to state_table
15246 * src/reader.c (packsymbols): Fill this table.
15248 * src/conflicts.c (resolve_sr_conflict): Adjust.
15249 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
15251 Use symbols[i]->tag instead of tags[i].
15253 2001-12-29 Akim Demaille <akim@epita.fr>
15255 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
15256 In addition, put a comment in there, to replace...
15257 * tests/regression.at (%union and C comments): Remove.
15259 2001-12-29 Akim Demaille <akim@epita.fr>
15261 * tests/regression.at (Web2c Actions): Blindly move the actual
15262 output as expected output. The contents *seem* right to me, but I
15263 can't pretend reading perfectly parser tables... Nonetheless, all
15264 the other tests pass correctly, the table look OK, even though the
15265 presence of `$axiom' is to be noted: AFAICS it is useless (but
15268 2001-12-29 Akim Demaille <akim@epita.fr>
15270 * src/reader.c (readgram): Don't add the rule 0 if there were no
15271 rules read. In other words, add it _after_ having performed
15272 grammar sanity checks.
15273 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
15275 2001-12-29 Akim Demaille <akim@epita.fr>
15277 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
15278 visible, and some states have now a different number.
15280 2001-12-29 Akim Demaille <akim@epita.fr>
15282 * src/reader.c (readgram): Bind the initial rule's lineno to that
15284 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
15285 (Solved SR Conflicts): Adjust rule 0's line number.
15287 2001-12-29 Akim Demaille <akim@epita.fr>
15289 Fix the `GAWK Grammar' failure.
15291 * src/LR0.c (final_state): Initialize to -1 so that we do compute
15292 the reductions of the first state which was mistakenly confused
15293 with the final state because precisely final_state was initialized
15295 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
15296 now noticed by Bison.
15297 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
15298 have a reduction on $default.
15300 2001-12-29 Akim Demaille <akim@epita.fr>
15302 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
15304 * src/closure.c (print_closure): Likewise.
15305 * src/derives.c (print_derives): Likewise.
15306 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
15309 2001-12-29 Akim Demaille <akim@epita.fr>
15311 * src/lalr.c (lookaheads_print): New.
15312 (lalr): Call it when --trace-flag.
15313 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
15316 2001-12-29 Akim Demaille <akim@epita.fr>
15318 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
15319 when walking through ritem, even via rule->rhs.
15320 * src/reduce.c (dump_grammar, useful_production, reduce_output)
15321 (useful_production, useless_nonterminals): Likewise.
15322 (reduce_grammar_tables): Likewise, plus update nritems.
15323 * src/nullable.c (set_nullable): Likewise.
15324 * src/lalr.c (build_relations): Likewise.
15325 * tests/sets.at (Nullable): Adjust.
15326 Fortunately, now, the $axiom is no longer nullable.
15328 2001-12-29 Akim Demaille <akim@epita.fr>
15330 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
15332 * src/gram.c (ritem_longest_rhs): Likewise.
15333 * src/reduce.c (nonterminals_reduce): Likewise.
15334 * src/print_graph.c (print_graph): Likewise.
15335 * src/output.c (output_rule_data): Likewise.
15336 * src/nullable.c (set_nullable): Likewise.
15338 2001-12-29 Akim Demaille <akim@epita.fr>
15340 * src/output.c: Comment changes.
15342 2001-12-27 Paul Eggert <eggert@twinsun.com>
15344 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
15345 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
15346 Sparc, as they were causing more porting problems than the
15347 (minor) performance improvement was worth.
15349 Also, catch up with 1.31's YYSTD.
15351 2001-12-27 Akim Demaille <akim@epita.fr>
15353 * src/output.c (output_gram): Rely on nritems, not the
15354 0-sentinel. See below.
15355 Use -1 as separator, not 0.
15356 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
15357 Rely on -1 as separator in yyrhs, instead of 0.
15358 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
15359 twice `Now at end of input', therefore there are two lines less to
15362 2001-12-27 Akim Demaille <akim@epita.fr>
15364 * tests/regression.at (Unresolved SR Conflicts):
15365 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
15368 2001-12-27 Akim Demaille <akim@epita.fr>
15370 * src/LR0.c (new_state): Recognize the final state by the fact it
15371 is reached by eoftoken.
15372 (insert_start_shifting_state, insert_eof_shifting_state)
15373 (insert_accepting_state, augment_automaton): Remove, since now
15374 these states are automatically computed from the initial state.
15375 (generate_states): Adjust.
15376 * src/print.c: When reporting a rule number to the user, substract
15377 1, so that the axiom rule is rule 0, and the first user rule is 1.
15378 * src/reduce.c: Likewise.
15379 * src/print_graph.c (print_core): For the time being, just as for
15380 the report, depend upon --trace-flags to dump the full set of
15382 * src/reader.c (readgram): Once the grammar read, insert the rule
15383 0: `$axiom: START-SYMBOL $'.
15384 * tests/set.at: Adjust: rule 0 is now displayed, and since the
15385 number of the states has changed (the final state is no longer
15386 necessarily the last), catch up.
15388 2001-12-27 Akim Demaille <akim@epita.fr>
15390 Try to make the use of the eoftoken valid. Given that its value
15391 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
15392 is used instead of > 0 where appropriate, (ii), depend upon nritems
15393 instead of the 0-sentinel.
15395 * src/gram.h, src/gram.c (nritems): New.
15396 Expected to be duplication of nitems, but for the time being...
15397 * src/reader.c (packgram): Assert nritems and nitems are equal.
15398 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
15399 * src/closure.c (print_closure, print_fderives): Likewise.

15401 * src/print.c (print_core, print_grammar): Likewise.
15402 * src/print_graph.c: Likewise.
15404 2001-12-27 Akim Demaille <akim@epita.fr>
15406 * src/main.c (main): If there are complains after grammar
15407 reductions, then output the report anyway if requested, then die.
15408 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
15409 * src/reader.c (eoftoken): New.
15410 (parse_token_decl): If the token being defined has value `0', it
15412 (packsymbols): No longer hack `tags' to insert `$' by hand.
15413 Be sure to preserve the value of the eoftoken.
15414 (reader): Make sure eoftoken is defined.
15415 Initialize nsyms to 0: now eoftoken is created just like the others.
15416 * src/print.c (print_grammar): Don't special case the eof token.
15417 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
15418 lie anyway, albeit pleasant.
15419 * tests/calc.at: Exercise error messages with eoftoken.
15420 Change the grammar so that empty input is invalid.
15421 Adjust expectations.
15422 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
15424 2001-12-27 Akim Demaille <akim@epita.fr>
15426 * configure.in: Check the protos of strchr ans strspn.
15427 Replace strchr if needed.
15428 * src/system.h: Provide the protos of strchr, strspn and memchr if
15430 * lib/strchr.c: New.
15431 * src/reader.c (symbols_save): Use strchr.
15433 2001-12-27 Akim Demaille <akim@epita.fr>
15435 * src/print.c, src/print_graph.c (escape): New.
15436 Use it to quote the TAGS outputs.
15437 * src/print_graph.c (print_state): Now errors are in red, and
15438 reductions in green.
15439 Prefer high to wide: output the state number on a line of its own.
15441 2001-12-27 Akim Demaille <akim@epita.fr>
15443 * src/state.h, src/state.c (reductions_new): New.
15444 * src/LR0.c (set_state_table): Let all the states have a
15445 `reductions', even if reduced to 0.
15446 (save_reductions): Adjust.

15464 2001-12-27 Akim Demaille <akim@epita.fr>
15466 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
15467 * src/print.c: here.
15468 (lookaheadset, shiftset): New, used as additional storage by
15470 (print_results): Adjust.
15471 (print_shifts, print_gotos, print_errs): New, extracted from...
15472 (print_actions): here.
15473 * src/print_graph.c (print_actions): Remove dead code.
15475 2001-12-27 Akim Demaille <akim@epita.fr>
15477 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
15480 2001-12-27 Akim Demaille <akim@epita.fr>
15482 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
15483 (build_relations): Adjust.
15485 2001-12-27 Akim Demaille <akim@epita.fr>
15487 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
15490 2001-12-27 Akim Demaille <akim@epita.fr>
15492 * src/reader.c (packgram): Catch nitems overflows.
15494 2001-12-27 Akim Demaille <akim@epita.fr>
15496 * src/files.c, src/files.h (guard_obstack): Remove.
15497 * src/output.c (output): Adjust.
15498 * src/reader.c (parse_braces): New, factoring...
15499 (copy_action, copy_guard): these two which are renamed as...
15500 (parse_action, parse_guard): these.
15501 As a voluntary consequence, using braces around guards is now
15504 2001-12-27 Akim Demaille <akim@epita.fr>
15506 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
15507 * src/reader.c (symbol_list): `guard' and `guard_line' are new
15509 (symbol_list_new): Adjust.
15510 (copy_action): action_line is the first line, not the last.
15511 (copy_guard): Just as for actions, store the `action' only, not
15512 the switch/case/break flesh.
15513 Don't parse the user action that might follow the guard, let...
15514 (readgram): do it, i.e., now, there can be an action after a
15516 In other words the guard is just explicitly optional.
15517 (packgram): Adjust.
15518 * src/output.c (guards_output): New.
15519 (output_parser): Call it when needed.
15520 (output): Also free the guard and attrs obstacks.
15521 * src/files.c, src/files.h (obstack_save): Remove.
15522 (output_files): Remove.
15523 As a result, if one needs the former `.act' file, using an
15524 appropriate skeleton which requires actions and guards is now
15526 * src/main.c (main): Adjust.
15527 * tests/semantic.at: New.
15528 * tests/regression.at: Use `input.y' as input file name.
15529 Avoid 8+3 problems by requiring input.c when the test needs the
15532 2001-12-27 Akim Demaille <akim@epita.fr>
15534 * src/reader.c (symbol_list_new): Be sure to initialize all the
15537 2001-12-27 Akim Demaille <akim@epita.fr>
15539 All the hacks using a final pseudo state are now useless.
15541 * src/LR0.c (set_state_table): state_table holds exactly nstates.
15542 * src/lalr.c (nLA): New.
15543 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
15544 instead of lookaheadsp from the pseudo state (nstate + 1).
15546 2001-12-27 Akim Demaille <akim@epita.fr>
15548 * src/output.c (action_row, token_actions): Use a state_t instead
15549 of a integer, and nlookaheads instead of the following state's

15556 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
15557 (conflicts_print, print_reductions): Use a state_t instead of an
15558 integer when referring to a state.
15559 As much as possible, depend upon nlookaheads, instead of the
15560 `lookaheadsp' member of the following state (since lookaheads of
15561 successive states are successive, the difference between state n + 1
15562 and n served as the number of lookaheads for state n).
15563 * src/lalr.c (add_lookback_edge): Likewise.
15564 * src/print.c (print_core, print_actions, print_state)
15565 (print_results): Likewise.

15572 * src/bison.hairy: Formatting/comment changes.
15574 Remove `register' indications.
15575 Add plenty of `static'.
15577 2001-12-27 Akim Demaille <akim@epita.fr>
15579 * src/output.c (prepare): Drop the muscle `ntbase' which
15580 duplicates ntokens.
15581 * src/bison.simple: Formatting/comment changes.
15582 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
15583 is an undocumented synonym.
15585 2001-12-22 Akim Demaille <akim@epita.fr>
15587 * src/output.c (output_table_data): Change the prototype to use
15588 `int' for array ranges: some invocations do pass an int, not a
15590 Reported by Wayne Green.
15592 2001-12-22 Akim Demaille <akim@epita.fr>
15594 Some actions of web2c.y are improperly triggered.
15595 Reported by Mike Castle.
15597 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
15598 * tests/regression.at (Web2c): Rename as...
15599 (Web2c Report): this.
15600 (Web2c Actions): New.
15602 2001-12-22 Akim Demaille <akim@epita.fr>
15604 Reductions in web2c.y are improperly reported.
15605 Reported by Mike Castle.
15607 * src/conflicts.c (print_reductions): Fix.
15608 * tests/regression.at (Web2c): New.
15610 2001-12-18 Akim Demaille <akim@epita.fr>
15612 Some host fail on `assert (!"foo")', which expands to
15613 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
15614 Reported by Nelson Beebee.
15616 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
15617 `#define it_succeeded 0' and `assert (it_succeeded)'.
15619 2001-12-17 Marc Autret <autret_m@epita.fr>
15621 * src/bison.simple: Don't hard code the skeleton line and filename.
15622 * src/output.c (output_parser): Rename 'line' as 'output_line'.
15623 New line counter 'skeleton_line' (skeleton-line muscle).
15625 2001-12-17 Paul Eggert <eggert@twinsun.com>
15627 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
15628 YYDEBUG must be defined to a nonzero value.
15630 * src/bison.simple (yytname): Do not assume that the user defines
15631 YYDEBUG to a properly parenthesized expression.
15633 2001-12-17 Akim Demaille <akim@epita.fr>
15635 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
15636 nlookaheads is a new member.
15638 * src/lalr.h (nlookaheads): Remove this orphan declaration.
15639 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
15642 2001-12-17 Akim Demaille <akim@epita.fr>
15644 * src/files.h, src/files.c (open_files, close_files): Remove.
15645 * src/main.c (main): Don't open/close files, nor invoke lex_free,
15647 * src/reader.c (reader): Do it.
15649 2001-12-17 Akim Demaille <akim@epita.fr>
15651 * src/conflicts.c (print_reductions): Formatting changes.
15653 2001-12-17 Akim Demaille <akim@epita.fr>
15655 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
15656 (flush_reduce): New.
15657 (resolve_sr_conflict): Adjust.
15659 2001-12-17 Akim Demaille <akim@epita.fr>
15661 * src/output.c (output_obstack): Be static and rename as...
15662 (format_obstack): this, to avoid any confusion with files.c's
15664 * src/reader.h (muscle_obstack): Move to...
15665 * src/output.h: here, since it's defined in output.c.
15667 2001-12-17 Akim Demaille <akim@epita.fr>
15669 * src/output.c (action_row, save_column, default_goto)
15670 (sort_actions, matching_state, pack_vector): Better variable
15673 2001-12-17 Akim Demaille <akim@epita.fr>
15675 * src/output.c: Various formatting changes.
15677 2001-12-17 Akim Demaille <akim@epita.fr>
15679 * src/files.c (output_files): Free the output_obstack.
15680 * src/main.c (main): Call print and print_graph conditionally.
15681 * src/print.c (print): Work unconditionally.
15682 * src/print_graph.c (print_graph): Work unconditionally.
15683 * src/conflicts.c (log_resolution): Output only if verbose_flag.
15685 2001-12-16 Marc Autret <autret_m@epita.fr>
15687 * src/output.c (actions_output): Fix. When we use %no-lines,
15688 there is one less line per action.
15690 2001-12-16 Marc Autret <autret_m@epita.fr>
15692 * src/bison.simple: Remove a useless #line directive.
15693 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
15694 * src/output.c (get_lines_number): New.
15695 (output_parser): Adjust, now takes care about the lines of a
15697 Fix line numbering.
15698 (actions_output): Computes the number of lines taken by actions.
15699 (output_master_parser): Insert new skeleton which is the name of
15700 the output parser file name.
15702 2001-12-15 Marc Autret <autret_m@epita.fr>
15704 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
15706 2001-12-15 Marc Autret <autret_m@epita.fr>
15708 * src/output.c (output_gram): Keep track of the hairy one.
15710 2001-12-15 Akim Demaille <akim@epita.fr>
15712 Make `make distcheck' work.
15714 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
15715 system.h which uses libgettext.h.
15717 2001-12-15 Akim Demaille <akim@epita.fr>
15719 * src/nullable.c (set_nullable): Useless rules must be skipped,
15720 otherwise, since we range over their symbols, we might look at a
15721 nonterminal which no longer ``exists'', i.e., it is not counted in
15722 `nvars', hence we overflow our arrays.
15724 2001-12-15 Akim Demaille <akim@epita.fr>
15726 The header can also be produced directly, without any obstack!
15729 * src/files.c, src/files.h (defines_obstack): Remove.
15730 (compute_header_macro): Global.
15731 (defines_obstack_save): Remove.
15732 * src/reader.c (parse_union_decl): No longer output to
15733 defines_obstack: its content can be found in the `stype' muscle
15735 (output_token_translations): Merge into...
15736 (symbols_output): this.
15738 (symbols_save): this.
15740 * src/output.c (header_output): New.
15743 2001-12-15 Akim Demaille <akim@epita.fr>
15745 * src/reader.c (parse_union_decl): Instead of handling two obstack
15746 simultaneously, use one to define the `stype' muscle, and use the
15747 value of the latter to fill defines_obstack.
15748 (copy_comment): Remove.
15749 (copy_comment2): Work for a single obstack.
15751 (copy_comment): this.
15753 2001-12-15 Akim Demaille <akim@epita.fr>
15755 * src/lex.c, src/lex.h (xgetc): No longer static.
15756 * src/reader.c (parse_union_decl): Revamp.
15758 2001-12-15 Akim Demaille <akim@epita.fr>
15760 Still making progress in separating Bison into (i) input, (ii)
15761 process, (iii) output: now we can directly output the parser file
15762 without using table_obstack at all.
15764 * src/files.c, src/files.h (table_obstack): Bye bye.
15765 (parser_file_name): New.
15766 * src/files.c (compute_output_file_names): Compute it.
15767 * src/output.c (actions_output, output_parser)
15768 (output_master_parser): To a file instead of an obstack.
15770 2001-12-15 Akim Demaille <akim@epita.fr>
15772 Attach actions to rules, instead of pre-outputting them to
15775 * src/gram.h (rule_t): action and action_line are new members.
15776 * src/reader.c (symbol_list): Likewise.
15777 (copy_action): Save the actions within the rule.
15778 (packgram): Save them in rule_table.
15779 * src/output.c (actions_output): New.
15780 (output_parser): Use it on `%%actions'.
15781 (output_rule_data): Don't free rule_table.
15783 (prepare): Don't save the `action' muscle.
15784 * src/bison.simple: s/%%action/%%actions/.
15786 2001-12-15 Akim Demaille <akim@epita.fr>
15788 * src/reader.c (copy_action): When --yacc, don't append a `;'
15789 to the user action: let it fail if lacking.
15790 Suggested by Arnold Robbins and Tom Tromey.
15792 2001-12-14 Akim Demaille <akim@epita.fr>
15794 * src/lex.c (literalchar): Simply return the char you decoded, non
15795 longer mess around with obstacks and int pointers.
15796 Adjust all callers.
15798 2001-12-14 Akim Demaille <akim@epita.fr>
15800 * src/lex.c (literalchar): Don't escape the special characters,
15801 just decode them, and keep them as char (before, eol was output as
15802 the 2 char string `\n' etc.).
15803 * src/output.c (output_rule_data): Use quotearg to output the
15806 2001-12-13 Paul Eggert <eggert@twinsun.com>
15808 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
15809 Do not infringe on the global user namespace when using C++.
15810 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
15811 All uses of `fprintf' and `stderr' changed.
15813 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
15815 2001-12-13 Akim Demaille <akim@epita.fr>
15817 The computation of nullable is broken: it doesn't handle empty
15820 * tests/torture.at (GNU AWK Grammar): New.
15821 * tests/sets.at (Nullable): New.
15822 * src/nullable.c (set_nullable): Instead of blindly looping over
15823 `ritems', loop over the rules, and then over their rhs's.
15825 Work around Autotest bugs.
15827 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
15828 frame, because Autotest understand lines starting with a `+' as
15829 traces from the shell. Then, they are not processed properly.
15830 Admittedly an Autotest bug, but we don't have time to wait for
15831 Autotest to catch up.
15832 * tests/regression.at (Broken Closure): Adjust to the new table
15835 * tests/sets.at: here.
15837 2001-12-13 Akim Demaille <akim@epita.fr>
15839 * src/closure.c (closure): Use nrules instead of playing tricks
15840 with BITS_PER_WORD.
15842 2001-12-13 Akim Demaille <akim@epita.fr>
15844 * src/print.c (print_actions): Output the handling of `$' as the
15845 traces do: shifting the token EOF. Before EOF was treated as a
15847 * tests/regression.at: Adjust some tests.
15848 * src/print_graph.c (print_core): Complete the set of items via
15849 closure. The next-to-final and final states are still unsatisfying,
15850 but that's to be addressed elsewhere.
15851 No longer output the rule numbers, but do output the state number.
15852 A single loop for the shifts + gotos is enough, but picked a
15853 distinct color for each.
15854 (print_graph): Initialize and finalize closure.
15856 2001-12-13 Akim Demaille <akim@epita.fr>
15858 * src/reader.c (readgram): Remove dead code, an strip useless
15860 (get_type): Remove, unused.
15862 2001-12-12 Akim Demaille <akim@epita.fr>
15864 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
15865 on that of lib/error.c.
15867 2001-12-12 Akim Demaille <akim@epita.fr>
15869 Some hosts don't like `/' in includes.
15871 * src/system.h: Include libgettext.h without qualifying the path.
15872 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
15875 2001-12-11 Marc Autret <autret_m@epita.fr>
15877 * src/output.c (output_parser): Remove useless muscle.
15879 2001-12-11 Marc Autret <autret_m@epita.fr>
15881 * src/bison.simple: Remove #line just before %%epilogue. It
15882 is now handled in ...
15883 * src/reader.c (read_additionnal_code): Add the output of a
15884 #line for the epilogue.
15886 2001-12-10 Marc Autret <autret_m@epita.fr>
15888 * src/reader.c (copy_definition): Re-use CPP-outed code which
15889 replace precedent remove.
15890 * src/bison.simple: Remove #line before %%prologue because
15891 %%input-line is wrong at this time.
15893 2001-12-10 Marc Autret <autret_m@epita.fr>
15895 * src/reader.c (symbols_output): Clean up.
15896 * src/output.c (output_gram, output): Clean up.
15898 2001-12-10 Akim Demaille <akim@epita.fr>
15900 * src/lalr.c (initialize_lookaheads): New. Extracted from...
15901 * src/LR0.c (set_state_table): here.
15902 * src/lalr.c (lalr): Call it.
15904 2001-12-10 Akim Demaille <akim@epita.fr>
15906 * src/state.h (shifts): Remove the `number' member: shifts are
15907 attached to state, hence no longer need to be labelled with a
15910 2001-12-10 Akim Demaille <akim@epita.fr>
15912 Now that states have a complete set of members, the linked list of
15913 shifts is useless: just fill directly the state's shifts member.
15915 * src/state.h (shifts): Remove the `next' member.
15916 * src/LR0.c (first_state, last_state): Remove.
15917 Adjust the callers.
15918 (augment_automaton): Don't look for the shifts that must be added
15919 a shift on EOF: it is those of the state we looked for! But now,
15920 since shifts are attached, it is no longer needed to looking
15921 merely by its id: its number.
15923 2001-12-10 Akim Demaille <akim@epita.fr>
15925 * src/LR0.c (augment_automaton): Better variable locality.
15926 Remove an impossible branch: if there is a state corresponding to
15927 the start symbol being shifted, then there is shift for the start
15928 symbol from the initial state.
15930 2001-12-10 Akim Demaille <akim@epita.fr>
15932 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
15933 only when appropriate: when insert_start_shifting_state' is not
15935 * tests/regression.at (Rule Line Numbers): Adjust.
15937 2001-12-10 Akim Demaille <akim@epita.fr>
15939 * src/LR0.c (augment_automaton): Now that all states have shifts,
15940 merge the two cases addition shifts to the initial state.
15942 2001-12-10 Akim Demaille <akim@epita.fr>
15944 * src/lalr.c (set_state_table): Move to...
15946 * src/lalr.c (lalr): Don't call it...
15947 * src/LR0.c (generate_states): do it.
15948 * src/LR0.h (first_state): Remove, only the table is used.
15950 2001-12-10 Akim Demaille <akim@epita.fr>
15952 * src/LR0.h (first_shift, first_reduction): Remove.
15953 * src/lalr.c: Don't use first_shift: find shifts through the
15956 2001-12-10 Akim Demaille <akim@epita.fr>
15958 * src/LR0.c: Attach shifts to states as soon as they are
15960 * src/lalr.c (set_state_table): Instead of assigning shifts to
15961 state, just assert that the mapping was properly done.
15963 2001-12-10 Akim Demaille <akim@epita.fr>
15965 * src/LR0.c (insert_start_shift): Rename as...
15966 (insert_start_shifting_state): this.
15967 (insert_eof_shifting_state, insert_accepting_state): New.
15968 (augment_automaton): Adjust.
15969 Better locality of the variables.
15970 When looking if the start_symbol is shifted from the initial
15971 state, using `while (... symbol != start_symbol ...)' sounds
15972 better than `while (... symbol < start_symbol ...)': If fail
15973 to see how the order between symbols could be relevant!
15975 2001-12-10 Akim Demaille <akim@epita.fr>
15977 * src/getargs.h: Don't declare `spec_name_prefix' and
15978 `spec_file_prefix', declared by src/files.h.
15979 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
15980 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
15981 * src/output.c (prepare): Adjust.
15982 * src/reader.c (symbols_output): Likewise.
15983 * src/vmsgetargs.c: Vaguely adjust, but who cares?
15985 2001-12-10 Akim Demaille <akim@epita.fr>
15987 * src/muscle_tab.c (muscle_init): NULL is a better default than
15990 2001-12-10 Akim Demaille <akim@epita.fr>
15992 * src/reader.c (reader): Calling symbols_output once is enough.
15994 2001-12-10 Akim Demaille <akim@epita.fr>
15996 Now that states have a complete set of members, the linked list of
15997 reductions is useless: just fill directly the state's reductions
16000 * src/state.h (struct reductions): Remove member `number' and
16002 * src/LR0.c (first_reduction, last_reduction): Remove.
16003 (save_reductions): Don't link the new reductions, store them in
16005 * src/lalr.c (set_state_table): No need to attach reductions to
16006 states, it's already done.
16007 * src/output.c (output_actions): No longer free the shifts, then
16008 the reductions, then the states: free all the states and their
16011 2001-12-10 Akim Demaille <akim@epita.fr>
16013 * src/options.c (OPTN, DRTV, BOTH): New.
16014 (option_table): Use them.
16016 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
16017 the job of system.h.
16018 * src/options.c: Don't include stdio.h and xalloc.h for the same
16021 2001-12-10 Akim Demaille <akim@epita.fr>
16023 * src/output.c (output, prepare): Make sure the values of the
16024 muscles `action' and `prologue' are 0-terminated.
16026 2001-12-10 Akim Demaille <akim@epita.fr>
16028 Clean up GCC warnings.
16030 * src/reader.c (copy_action): `buf' is not used.
16031 (parse_skel_decl): Be static.
16032 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
16033 * src/options.h (create_long_option_table): Have a real prototype.
16034 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
16035 (hash_delete_at): Return const void *.
16036 Adjust casts to preserve the const.
16038 2001-12-10 Akim Demaille <akim@epita.fr>
16040 * configure.in: Require 2.52g.
16041 M4 is not needed, but AUTOM4TE is.
16042 * m4/m4.m4: Remove.
16043 * tests/Makefile.am: Adjust.
16045 2001-12-10 Akim Demaille <akim@epita.fr>
16047 One structure for states is enough, even though theoretically
16048 there are LR(0) states and LALR(1) states.
16050 * src/lalr.h (state_t): Remove.
16051 (state_table): Be state_t **, not state_t *.
16052 * src/state.h (core, CORE_ALLOC): Rename as...
16053 (state_t, STATE_ALLOC): this.
16054 Add the LALR(1) members: shifts, reductions, errs.
16055 * src/LR0.c (state_table): Rename as...
16056 (state_hash): this, to avoid name clashes with the global
16058 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
16059 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
16061 2001-12-10 Akim Demaille <akim@epita.fr>
16063 Bison dumps core on bash.y.
16064 Reported by Pascal Bart.
16066 * src/warshall.c (bitmatrix_print): New.
16068 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
16069 j must be the outer loop.
16070 * tests/regression.at (Broken Closure): New.
16072 2001-12-05 Akim Demaille <akim@epita.fr>
16074 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
16076 Reported by Peter Hamorsky.
16078 2001-12-05 Akim Demaille <akim@epita.fr>
16080 * src/conflicts.c (err_table): Remove.
16081 (resolve_sr_conflict): Adjust.
16082 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
16084 (state_t.reductions, state_t.shifts): this.
16086 2001-12-05 Akim Demaille <akim@epita.fr>
16088 * src/reduce.c (reduce_grammar_tables): No longer disable the
16089 removal of useless rules via CPP but via `if (0)', so that the
16090 compiler still check the code is valid.
16091 For instance, it should have noticed `rline' no longer exists: use
16092 the `line' member of rule_t.
16093 * src/gram.c (dummy, rline): Remove, unused.
16095 2001-12-05 Akim Demaille <akim@epita.fr>
16097 * src/output.c (pack_vector): Use assert, not berror.
16098 * src/main.c (berror): Remove, unused.
16100 2001-12-05 Akim Demaille <akim@epita.fr>
16102 New experimental feature: if --verbose --trace output all the
16103 items of a state, not only its kernel.
16105 * src/print.c (print_core): If `trace_flag', then invoke closure
16106 before outputting the items of the state (print_core is no longer
16107 a correct name them).
16108 (print_results): Invoke new_closure/free_closure if needed.
16110 2001-12-05 Akim Demaille <akim@epita.fr>
16112 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
16113 * src/closure.c, src/closure.h (itemsetsize): Rename as...
16114 (nitemset): for consistency with the rest of the project.
16116 2001-12-05 Akim Demaille <akim@epita.fr>
16118 * src/closure.c (print_closure): Improve.
16119 (closure): Use it for printing input and output.
16121 2001-12-05 Akim Demaille <akim@epita.fr>
16123 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
16124 indexed by nonterminals.
16126 2001-12-05 Akim Demaille <akim@epita.fr>
16128 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
16130 * src/warshall.h: Remove accidental duplication of the content.
16132 2001-12-05 Akim Demaille <akim@epita.fr>

16144 2001-12-05 Akim Demaille <akim@epita.fr>
16146 * src/output.c (action_row): De-obfuscate
16147 using the good o' techniques: arrays not pointers, variable
16148 locality, BITISSET, RESETBIT etc.
16150 2001-12-05 Akim Demaille <akim@epita.fr>
16152 Pessimize the code to simplify it: from now on, all the states
16153 have a valid SHIFTS, which NSHIFTS is possibly 0.
16155 * src/LR0.c (shifts_new): Be global and move to..
16156 * src/state.c, src/state.h: here.
16157 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

16163 * src/conflicts.c: Use it.
16164 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
16165 incorrectly ``simplified''.

16169 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
16170 using the good o' techniques: arrays not pointers, variable
16171 locality, BITISSET, RESETBIT etc.
16173 2001-12-05 Akim Demaille <akim@epita.fr>
16175 * src/state.h (SHIFT_SYMBOL): New.

16205 2001-12-05 Akim Demaille <akim@epita.fr>
16207 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

16223 * src/lalr.c (maxrhs): Move to...
16224 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
16225 * src/lalr.c (build_relations): Adjust.
16227 2001-12-05 Akim Demaille <akim@epita.fr>
16229 * src/lalr.c (transpose): Free the memory allocated to the
16230 argument, as it is replaced by the results by the unique caller.
16231 (build_relations): Merely invoke transpose: it handles the memory
16233 Improve variable locality.
16234 Avoid variables used as mere abbreviations.
16235 (compute_lookaheads): Use arrays instead of pointers.
16237 2001-12-05 Akim Demaille <akim@epita.fr>
16239 * src/lalr.c (initialize_F): Improve variable locality.
16240 Avoid variables used as mere abbreviations.

16253 2001-12-05 Akim Demaille <akim@epita.fr>
16255 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
16256 the handling of squeue.
16257 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16259 2001-12-05 Akim Demaille <akim@epita.fr>
16261 Because useless nonterminals are now kept alive (instead of being
16262 `destroyed'), we now sometimes examine them, and store information
16263 related to them. Hence we need to know their number, and adjust
16264 memory allocations.
16266 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
16268 * src/LR0.c (allocate_itemsets): The memory allocated to
16269 `symbol_count' was used for two different purpose: once to count
16270 the number of occurrences of each symbol, and later reassigned to
16271 `shift_symbol', containing the symbol that can be shifted from a
16273 Deobfuscate, i.e., allocate, use and free `symbol_count' here
16275 (new_itemsets): Allocate `shift_symbol' here.
16276 (allocate_itemsets): symbol_count includes useless nonterminals.
16277 Make room for them.
16278 (free_storage): Use `free', not `XFREE', for pointers that cannot
16281 2001-12-05 Akim Demaille <akim@epita.fr>
16283 * src/nullable.c (set_nullable): Deobfuscate the handling of
16285 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16287 2001-12-05 Akim Demaille <akim@epita.fr>
16289 * src/gram.c, src/gram.h (ritem_print): New.
16290 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
16291 (This useless function was defined only to work around VMS linkers
16292 that can't handle compilation units with variables only).
16293 * src/reduce.c (dump_grammar): Use it to trace the construction of
16296 2001-12-04 Paul Eggert <eggert@twinsun.com>
16298 * src/bison.simple (union yyalloc): Change member names
16299 to be the same as the stack names.
16300 (yyparse): yyptr is now union yyalloc *, not char *.
16301 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
16302 and may generate better code on some machines.
16303 (yystpcpy): Use prototype if __STDC__ is defined, not just
16304 if __cplusplus is defined.
16306 2001-11-30 Akim Demaille <akim@epita.fr>
16308 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
16309 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
16310 Gettext doesn't compile cleanly, and dies with -Werror.
16311 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
16312 Include WARNING_CFLAGS here.
16313 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
16314 before being defined.
16316 2001-11-27 Paul Eggert <eggert@twinsun.com>
16318 * lib/quotearg.h (quotearg_n, quotearg_n_style):
16319 First arg is int, not unsigned.
16320 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
16321 (SIZE_MAX, UINT_MAX): New macros.
16322 (quotearg_n_options): Abort if N is negative.
16323 Avoid overflow check on hosts where size_t is 64 bits and int
16324 is 32 bits, as overflow is impossible there.
16325 Fix off-by-one typo that caused unnecessary reallocation.
16327 2001-11-29 Paul Eggert <eggert@twinsun.com>
16329 Name space cleanup in generated parser.
16331 * doc/bison.texinfo (Bison Parser): Discuss system headers
16332 and their effect on the user name space.
16334 * src/bison.simple:
16335 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
16336 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
16337 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
16339 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
16340 on user names when possible.
16342 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
16343 Simplify test for whather <alloca.h> exists.
16345 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
16347 (<stdio.h>): Include if YYDEBUG.
16349 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
16350 ! defined (yyoverflow) && ! defined (yymemcpy).
16352 (yymemcpy, yyparse): Rename local variables as needed so that
16353 they all begin with 'yy'.
16355 (yystrlen, yystpcpy): New functions.
16357 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
16360 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
16361 instead of relying on string.h functions. Use YYSTACK_ALLOC
16362 and YYSTACK_FREE instead of malloc and free.
16364 2001-11-30 Akim Demaille <akim@epita.fr>
16366 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
16367 before their first uses.

16377 if body instead of `;' to pacify GCC's warnings.
16379 2001-11-30 Akim Demaille <akim@epita.fr>
16381 Instead of mapping the LHS of unused rules to -1, keep the LHS
16382 valid, but flag the rules as invalid.
16384 * src/gram.h (rule_t): `useful' is a new member.
16385 * src/print.c (print_grammar): Adjust.
16386 * src/derives.c (set_derives): Likewise.
16387 * src/reader.c (packgram, reduce_output): Likewise.
16388 * src/reduce.c (reduce_grammar_tables): Likewise.
16389 * tests/reduce.at (Underivable Rules, Useless Rules): New.
16391 2001-11-30 Akim Demaille <akim@epita.fr>

16398 2001-11-30 Akim Demaille <akim@epita.fr>
16400 * src/reduce.c (nonterminals_reduce): Instead of throwing away
16401 useless nonterminals, move them at the end of the symbol arrays.
16402 (reduce_output): Adjust.
16403 * tests/reduce.at (Useless Nonterminals): Adjust.
16405 2001-11-30 Akim Demaille <akim@epita.fr>

16414 * src/bison.simple (YYSTACK_REALLOC): Remove.
16415 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
16416 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
16418 (union yyalloc): New type.
16419 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
16420 an arbitrary restriction on hosts where size_t is wider than int.
16422 (yyparse): Don't dump core if alloca or malloc fails; instead, report
16423 a parser stack overflow. Allocate just one block of memory for all
16424 three stacks, instead of allocating three blocks; this typically is
16425 faster and reduces fragmentation.
16427 Do not limit the number of items in the stack to a value that fits
16428 in 'int', as this is an arbitrary limit on hosts with 64-bit
16429 size_t and 32-bit int.
16431 2001-11-29 Marc Autret <autret_m@epita.fr>
16433 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
16434 of defining YYERROR_VERBOSE.
16435 [AT_DATA]: $4 is now out of C declarations in the prologue.
16437 2001-11-28 Marc Autret <autret_m@epita.fr>

16447 * src/output.c (error_verbose): Define here.
16448 (prepare): Echo name modification.
16449 * src/getargs.h: Clean its extern declaration.
16450 * src/getargs.c (error_verbose_flag): Remove.

16481 * src/closure.c (closure): `b' and `ruleno' denote the same value:
16484 2001-11-28 Akim Demaille <akim@epita.fr>
16486 * src/closure.c (closure): Instead of looping over word in array
16487 then bits in words, loop over bits in array.
16489 2001-11-28 Akim Demaille <akim@epita.fr>
16491 * src/closure.c (closure): No longer optimize the special case
16492 where all the bits of `ruleset[r]' are set to 0, to make the code
16495 2001-11-28 Akim Demaille <akim@epita.fr>
16497 * src/closure.c (closure): `r' and `c' are new variables, used to
16498 de-obfuscate accesses to RULESET and CORE.

16505 2001-11-28 Akim Demaille <akim@epita.fr>
16507 * src/reduce.c (dump_grammar): Don't translate trace messages.
16509 2001-11-28 Akim Demaille <akim@epita.fr>
16511 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
16512 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
16513 as all tags are free'ed afterwards.

16516 2001-11-27 Paul Eggert <eggert@twinsun.com>
16518 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
16519 use alloca when we didn't want to, and vice versa.

16602 * src/conflicts.c (conflicts_print): Don't complain at all when
16603 there are no reduce/reduce conflicts, and as many shift/reduce
16604 conflicts as expected.
16605 * tests/regression.at (%expect right): Adjust.
16607 2001-11-23 Akim Demaille <akim@epita.fr>
16609 * lib/alloca.c: Update, from fileutils.

16628 2001-11-23 Akim Demaille <akim@epita.fr>
16630 Attaching lineno to buckets is stupid, since only one copy of each

16634 * src/reader.c (rline_allocated): Remove, unused.

18234 * src/conflicts.c (conflict_report): Be sure not to append to res
18235 between two calls, which could happen if both first sprintf were
18236 skipped, but not the first cp += strlen.
18238 2001-02-08 Akim Demaille <akim@epita.fr>
18240 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
18241 New, from fileutils 4.0.37.
18242 * configure.in: Require Autoconf 2.49c. I took some time before
18243 making this decision. This is the only way out for portability
18244 issues in Bison, it would mean way too much duplicate effort to
18245 import in Bison features implemented in 2.49c since 2.13.
18246 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
18248 2001-02-02 Akim Demaille <akim@epita.fr>

18263 2001-01-19 Akim Demaille <akim@epita.fr>
18265 * src/lex.h: Rename all the tokens:
18266 s/\bENDFILE\b/tok_eof/g;
18267 s/\bIDENTIFIER\b/tok_identifier/g;
18269 Let them be enums, not #define, to ease debugging.

18287 * src/reader.c (read_declarations): Adjust.
18288 * src/files.c (open_files): Don't call `compute_base_names', don't

18292 * src/output.c (output_headers): Document the fact that this patch
18293 introduces a guaranteed SEGV for semantic parsers.
18294 * doc/bison.texinfo: Document them.
18295 * tests/suite.at: Exercise these %options.
18297 2000-12-20 Akim Demaille <akim@epita.fr>

18309 2000-12-20 Akim Demaille <akim@epita.fr>
18311 * src/files.c (open_files): Fix the computation of short_base_name
18312 in the case of `-o foo.tab.c'.

18320 2000-12-20 Akim Demaille <akim@epita.fr>
18322 * src/files.c (open_files): Actually the `.output' file is based

18362 (obstack_grow_string): this.
18363 * src/output.c (output_parser): Recognize `%% actions' instead of
18365 * src/bison.s1: s/$/%% actions/.
18366 * src/bison.hairy: Likewise.
18368 2000-12-19 Akim Demaille <akim@epita.fr>
18370 * src/output.c (output_parser): Compute the `#line' lines when
18372 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
18373 Suggested by Hans Aberg.

18397 * src/files.c (open_files): Yipee! We no longer need all the code

18402 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

18429 * lib/obstack.h: Formatting changes.
18430 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
18431 prevents type checking.
18432 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
18433 cast the value to (void *): assigning a `foo *' to a `void *'

18455 Use them to declare the variables which are global or local to
18458 2000-11-17 Akim Demaille <akim@epita.fr>
18460 * acconfig.h: Remove, no longer used.
18462 2000-11-07 Akim Demaille <akim@epita.fr>
18464 * src: s/Copyright (C)/Copyright/g.
18466 2000-11-07 Akim Demaille <akim@epita.fr>
18468 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
18470 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

18486 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
18487 `const' their input argument (`data' or `address').
18488 Adjust the corresponding macros to include `const' in casts.
18490 2000-11-03 Akim Demaille <akim@epita.fr>
18492 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
18493 s/PFILE1/BISON_HAIRY/.
18494 Adjust dependencies.
18496 2000-11-03 Akim Demaille <akim@epita.fr>
18498 For some reason, this was not applied.
18500 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

18503 2000-11-03 Akim Demaille <akim@epita.fr>
18505 * src/files.c (skeleton_find): New function, eved out of...

18510 Don't use `atexit'.
18512 * src/files.c (obstack_save): New function.
18513 (done): Rename as...
18514 (output_files): this.
18515 Use `obstack_save'.
18516 * src/main.c (main): Don't use `atexit' to register `done', since
18517 it no longer has to remove tmp files, just call `output_files'
18518 when there are no errors.
18520 2000-11-02 Akim Demaille <akim@epita.fr>
18522 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
18523 `unlink': it's no longer used.
18524 * src/files.h: Formatting changes.
18526 2000-11-02 Akim Demaille <akim@epita.fr>
18528 Remove the last uses of mktemp and unlink/delete.
18530 * src/files.c (fdefines, ftable): Removed.
18531 (defines_ostack, table_obstack): New.
18532 Adjust dependencies of the former into uses of the latter.
18533 * src/output.c (output_short_or_char_table, output_short_table):

18590 * src/reader.c (copy_comment2): Expect the input stream to be on

18594 (copy_guard): Adjust.
18596 2000-10-16 Akim Demaille <akim@epita.fr>
18598 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
18599 `read_signed_integer'.
18601 2000-10-16 Akim Demaille <akim@epita.fr>
18603 * src/reader.c (copy_dollar): New function.
18604 (copy_guard, copy_action): Use it.
18606 2000-10-16 Akim Demaille <akim@epita.fr>
18608 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
18609 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
18610 New files, from Fileutils 4.0.27.
18611 * src/main.c (printable_version): Remove.

18618 2000-10-04 Akim Demaille <akim@epita.fr>
18620 * doc/bison.texinfo: Various typos spotted by Neil Booth.
18622 2000-10-04 Akim Demaille <akim@epita.fr>
18624 When a literal string is used to define two different tokens,
18625 `bison -v' segfaults.
18626 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
18628 * tests/regression.m4: New file.
18629 Include the core of the sample provided by Piotr Gackiewicz.
18630 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
18633 2000-10-04 Akim Demaille <akim@epita.fr>
18635 * src/reader.c (parse_expect_decl): Keep `count' within the size
18639 2000-10-02 Paul Eggert <eggert@twinsun.com>
18641 * bison.s1 (yyparse): Assign the default value

18645 2000-10-02 Akim Demaille <akim@epita.fr>
18647 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
18650 2000-10-02 Akim Demaille <akim@epita.fr>
18652 * src/derives.c, src/print.c, src/reduce.c: To ease the
18653 translation, move some `\n' out of the translated strings.
18655 2000-10-02 Akim Demaille <akim@epita.fr>
18657 The location tracking mechanism is precious for parse error
18658 messages. Nevertheless, it is enabled only when `@n' is used in
18659 the grammar, which is a different issue (you can use it in error
18660 message, but not in the grammar per se). Therefore, there should
18661 be another means to enable it.
18663 * src/getargs.c (getargs): Support `--locations'.
18664 (usage): Report it.
18665 * src/getargs.h (locationsflag): Export it.
18666 * src/lex.c (percent_table): Support `%locations'.
18667 * src/reader.c (yylsp_needed): Remove this variable, now replaced
18668 with `locationsflag'.
18669 * doc/bison.texinfo: Document `--locations' and `%locations'.
18671 * tests/calc.m4: Test it.
18673 For regularity of the names, replace each
18674 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
18675 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
18676 In addition replace each `flag' with `_flag'.
18678 2000-10-02 Akim Demaille <akim@epita.fr>
18680 Also test parse error messages, including with YYERROR_VERBOSE.
18682 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
18684 Use it to check the computations.
18685 Use it to check `nonassoc' is honored.
18686 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
18687 `--yyerror-verbose'.
18688 (_AT_CHECK_CALC): Adjust to this option.
18689 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
18691 2000-10-02 Akim Demaille <akim@epita.fr>
18693 Test also `--verbose', `--defines' and `--name-prefix'. Testing
18694 the latter demonstrates a flaw in the handling of non debugging
18695 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
18696 was used in order to simplify:
18712 unfortunately this leads to a CPP conflict when
18713 `--name-prefix=foo' is used since it produces `#define yydebug
18716 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
18717 (YYDPRINTF): New macro.
18719 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
18721 Also test `--verbose', `--defines' and `--name-prefix'.
18723 2000-10-02 Akim Demaille <akim@epita.fr>
18725 Improve the readability of the produced parsers.
18727 * src/bison.s1: Formatting changes.
18728 Improve the comment related to the `$' mark.
18729 (yydefault): Don't fall through to `yyresume': `goto' there.
18730 * src/output.c (output_parser): When the `$' is met, skip the end
18732 New variable, `number_of_dollar_signs', to check there's exactly
18733 one `$' in the parser skeleton.
18735 2000-10-02 Akim Demaille <akim@epita.fr>
18737 * lib/xstrdup.c: New file, from the fileutils.
18738 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
18739 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
18740 instead of strlen + xmalloc + strcpy.
18741 * src/symtab.c (copys): Remove, use xstrdup instead.
18743 2000-10-02 Akim Demaille <akim@epita.fr>
18745 * src/gram.h (associativity): New enum type which replaces the
18746 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
18747 `right_assoc', `left_assoc' and `non_assoc'.
18748 Adjust all dependencies.
18749 * src/reader.c: Formatting changes.
18750 (LTYPESTR): Don't define it, use it as a literal in
18751 `reader_output_yylsp'.
18752 * src/symtab.h (symbol_class): New enum type which replaces the
18753 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

18762 2000-10-02 Akim Demaille <akim@epita.fr>
18764 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
18765 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
18766 difficult and introduced a lot of core dump. It turns out that
18767 Bison used an implementation of `xmalloc' based on `calloc', and
18768 at various places it does depend upon the initialization to 0. I
18769 have not tried to isolate the pertinent places, and all the former
18770 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
18771 someone should address this issue.
18773 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
18774 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

18868 * src/output.c (token_actions): Introduce a temporary array,
18869 YYDEFACT, that makes it possible for this function to use
18870 output_short_table.
18872 2000-10-02 Akim Demaille <akim@epita.fr>
18874 `user_toknums' is output as a `short[]' in `output.c', while it is
18875 defined as a `int[]' in `reader.c'. For consistency with the
18876 other output tables, `user_toknums' is now defined as a table of

18920 * src/system.h: Define PARAMS.

19141 Change the handling of @s so that they behave exactly like $s.
19142 There is now a pseudo variable @$ (readble and writable), location
19143 of the lhs of the rule (by default ranging from the location of
19144 the first symbol of the rhs, to the location of the last symbol,
19145 or, if the rhs is empty, YYLLOC).
19147 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
19149 (yyparse): When providing a default semantic action, provide a

19152 same way you stack YYVAL.
19153 * src/reader.c (read_declarations): Use warns.
19154 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

19180 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

19873 an invalid character. Do not abort.
19874 (read_declarations, copy_guard, copy_action): Use
19875 printable_version to avoid unprintable characters in printed output.
19876 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.

19908 way to specify the flags -n, -l, and -r. Also added hooks for
19909 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
19910 major changes to files.c.
