478 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a ` '
479 instead of a `\n'. That is, don't add escapes yet or they'll be doubly
481 (xsl:template name="output-node"): Use the new escape template instead
482 of the string-replace template directly.
483 (xsl:template name="output-edge"): Likewise.
484 (xsl:template name="escape"): New, escapes backslashes and newlines in
485 addition to quotation marks.
486 * src/graphviz.c (start_graph, output_node, output_edge): Add
487 whitespace to output for legibility.
489 Make xml2text.xsl and --report produce the same output, and remove the
490 XML "conflicts" element since a conflict summary is easily extracted
492 * data/xslt/bison.xsl: New.
493 (xsl:template match="state" mode="bison:count-conflicts): New.
494 * data/xslt/xml2text.xsl: Import bison.xsl.
495 (xsl:template match="bison-xml-report"): Instead of styling the
496 "conflicts" element, style the "automaton" element with mode
497 "conflicts". Unlike the former, the latter lists S/R and R/R
498 conflicts for a state on the same line.
499 (xsl:template match="conflicts"): Remove.
500 (xsl:template match="conflict"): Remove.
501 (xsl:template match="terminal"): Line-wrap the list of rules in which
502 the terminal is used.
503 (xsl:template match="nonterminal"): Likewise for nonterminals.
504 (xsl:template match="automaton" mode="conflicts"): New.
505 (xsl:template match="state" mode="conflicts"): New.

507 (xsl:template name="ws-search"): New.
508 * data/xslt/xml2xhtml.xsl: Import bison.xsl.
509 (xsl:template match="bison-xml-report"): Instead of styling the
510 "conflicts" element, style the "automaton" element with mode
512 (xsl:template match="conflicts"): Remove.
513 (xsl:template match="conflict"): Remove.
514 (xsl:template match="automaton" mode="conflicts"): New.
515 (xsl:template match="state" mode="conflicts): New.
516 * src/conflicts.c (conflicts_output_xml): Remove.
517 * src/conflicts.h (conflicts_output_xml): Remove prototype.
518 * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml.
519 * src/print.c (print_grammar): Consistently wrap at the 66th column so
520 the corresponding XSLT is easier. Also, never wrap between a word and
521 the comma that follows it.
523 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>
525 Improve C++ namespace support. Discussed starting at
526 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
527 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
528 b4_namespace_close): New macros that interpret the %define variable
529 "namespace" so its value can contain "::" to indicate nested
531 * data/glr.cc (b4_namespace): Don't define, and replace all uses with
533 * data/lalr1.cc (b4_namespace): Likewise.
534 * data/location.cc (b4_namespace): Likewise.
535 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
536 inside a new table in the general %define entry. Document `%define
537 namespace' there as well. Point the %name-prefix entry to it since it
538 explains it more completely in the case of C++.
539 (C++ Bison Interface): Mention `%define namespace' instead of
541 (Table of Symbols): Remove the `%define push_pull' entry. The %define
543 * tests/c++.at (Relative namespace references): New test case.
544 (Absolute namespace references): New test case.
545 (Syntactically invalid namespace references): New test case.
546 * tests/input.at (C++ namespace reference errors): New test case.
548 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>
550 Add syncline support and location accessor to internal %define
552 * data/bison.m4 (b4_percent_define_get_loc): New.
553 (b4_percent_define_get_syncline): New.
554 (b4_percent_define_flag_if): Use b4_percent_define_get_loc.
555 (b4_percent_define_default): Record defining location as line 1 rather
556 than 0 for the sake of synchronizing #line's, and define
557 b4_percent_define_syncline(VARIABLE).
558 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
559 * src/muscle_tab.c (muscle_syncline_grow): New.
560 (muscle_code_grow): Use muscle_syncline_grow.
561 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and
562 define b4_percent_define_syncline(VARIABLE).

565 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
566 remove some unused variables.
567 (muscle_percent_define_default): Record defining location as line 1
568 rather than 0 for the sake of synchronizing #line's, and define
569 b4_percent_define_syncline(VARIABLE).
570 (muscle_percent_define_check_values): Use
571 muscle_percent_define_get_loc.
572 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
573 (muscle_percent_define_get_syncline): Prototype.
574 * tests/skeletons.at (%define Boolean variables: invalid skeleton
575 defaults): Update output for location change.
576 (Complaining during macro argument expansion): Extend to test
577 b4_percent_define_get_loc and b4_percent_define_get_syncline errors.

581 Fix some error-reporting macro bugs.
582 * data/bison.m4 (b4_cat): New.
583 (b4_error, b4_error_at): Use b4_cat to send error directives directly
584 to stdout so they don't become arguments to other macros. Update
585 comments and add examples.
586 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
588 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
589 after printing the error directive so that M4 doesn't report subsequent
590 problems that are induced by this problem.
591 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
592 instead of just in them. Recognize @\n in both places. Both expand to
593 the empty string. Needed by b4_cat.
594 * tests/skeletons.at (Complaining during macro argument expansion):
596 (Fatal errors make M4 exit immediately): New test case.
598 2007-10-04 Joel E. Denny <jdenny@ces.clemson.edu>

606 computation from here...
607 (prepare): ... and from here...
608 (compute_pkgdatadir): ... into this new function.

615 (xml_escape_n): ... the static local variable buf here.
616 (print_xml): Free memory for escape_bufs.
617 * src/reduce.c (reduce_xml): XML-escape terminal symbol tags.
619 2007-09-25 Joel E. Denny <jdenny@ces.clemson.edu>
621 Replace `%push-parser' and `%push-pull-parser' with
622 `%define push_pull "push"' and `%define push_pull "both"'.
623 `%define push_pull "pull"' is the default.

625 Pull Parser Function, Parser Create Function, Parser Delete Function):
627 (Decl Summary, Table of Symbols): Replace %push-parser and

632 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
634 * data/push.c: ... to here and compute them from the value of the
635 %define variable push_pull.
636 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
637 parsing requests here...
638 * data/yacc.c: ... hack this to switch to push.c any time
639 b4_use_push_pull_flag or the %define variable push_pull is set. This
640 will go away when we mv push.c yacc.c.
641 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
642 push parsing is not supported since unused %define variables are
644 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
645 * src/muscle_tab.h (muscle_percent_define_check_values): Update
646 comments for consistency with b4_percent_define_check_values.
647 * src/output.c (prepare): Don't insert b4_pull_flag and b4_push_flag
649 * src/parse-gram.y (PERCENT_PUSH_PARSER, PERCENT_PUSH_PULL_PARSER):

677 Problem reported by Wojciech Polak.
678 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.
679 (xml_printf): Undo change I made on 21 September; that is,
680 indent 2 spaces, not 1.
682 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
684 Pacify ./configure --enable-gcc-warnings.

692 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
694 * src/print-xml.c: Prefer "const" after types; that's more consistent.
695 (xml_printf): Indent just 1 space for level.
696 (e_char, xlate_char): Remove.
697 (xml_escape_string): Rewrite to avoid undefined behavior (used
698 storage that was freed from the stack).

768 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
770 In impure push mode, don't allow more than one yypstate to be allocated
771 since multiple impure parsers would corrupt yynerrs.
772 * data/push.c (yypstate_allocated): New static global variable
774 (yypull_parse): If yypstate_new returns 0, don't report it as memory
775 exhaustion if yypstate_allocated is 1, but still return 2.
776 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is

853 Get rid of broken %no-parser, -n, and --no-parser implementation and
855 * TODO: Don't mention them.
856 * doc/bison.1: Likewise.
857 * doc/bison.texinfo (Decl Summary): Likewise.
858 (Bison Options): Likewise.
859 (Option Cross Key): Likewise.
860 * src/getargs.c (no_parser_flag): Remove global variable.
861 (usage): Don't print description of -n and --no-parser.
862 (long_options): Remove --no-parser entry here.
863 (getargs): Remove -n case in the switch here.
864 * src/getargs.h (no_parser_flag): Remove extern.
865 * tests/regression.at (Web2c Actions): Remove comment that mentions
868 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
870 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
871 name user variables starting with `yy'. Just pass NULL instead of a
872 dummy local &yylval to yypush_parse.
873 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
876 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
878 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
879 true since it's then always used regardless of whether yyoverflow is
880 defined. Reported by Christian Burger at
881 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
882 * THANKS: Add Christian Burger.
884 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
885 node names: say "Decl Summary" not "Bison Declaration Summary".
887 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
889 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
890 determine whether this function has already complained about an invalid
891 value for a %define boolean variable, don't check whether Bison has
892 ever examined the value. As written, the check was a tautology.
893 Instead, record and check for this complaint using a separate muscle.
895 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
897 Fix push parsing memory leak reported by Brandon Lucia at
898 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
899 * THANKS: Add Brandon Lucia.
900 * data/push.c (yypstate_delete): Free the stack if it was reallocated
901 but the parse never completed and thus freed it.
902 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
903 * tests/testsuite.at: Include push.at.
905 (Push Parsing: Memory Leak for Early Deletion): New test case.
907 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
909 Improve handling of multiple S/R conflicts in the same state and of S/R
910 conflicts involving multiple reductions.
911 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
912 set for a state here or Bison will abort if it is reassigned on a
913 later conflicted reduction in the same state.
914 Similarly, don't finalize and assign the solved conflicts report here
915 or it will be lost if it is reassigned on a later conflicted reduction
917 (set_conflicts): Instead, assign them both here after all S/R conflicts
918 in the state have been fully examined.
919 * src/print.c (shift_set): Rename to...
920 (no_reduce_set): ... this.
921 (print_reductions): Update for rename, and add %nonassoc error action
922 tokens to no_reduce_set so that, when printing the first remaining
923 reduction on an error action token, the reduction is enclosed in
925 (print_results): Update for rename.
926 * tests/conflicts.at (Solved conflicts report for multiple reductions
927 in a state): New test case.
928 (%nonassoc error actions for multiple reductions in a state): New test
931 * src/main.c (main): Don't depend on C99 features.
933 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
935 * build-aux/.cvsignore: Add compile.
936 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
939 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
941 * bootstrap (slurp): Create target directories that don't exist.
942 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
944 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
946 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
948 * closure.c (closure): Likewise.
949 * state.h (reductions): Comment sorting of rules.
950 (state): Comment sorting of items.
952 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
954 Fix C++ test cases after recent Gnulib changes. Discussed starting at
955 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
956 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
957 definition in order to avoid Gnulib headers since we don't use config.h
959 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
960 rather than AT_DATA so that config.h is included.
962 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
964 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
965 instead of fprintf. Guard these functions with #if YYDEBUG instead of
966 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
967 and so that YYFPRINTF is guaranteed to be defined here.
969 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
971 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
973 (muscle_percent_define_check_values): ... this more helpful function.
974 Again, it's not used yet, but it will be.
975 * src/muscle_tab.h: Likewise.
977 Improve some comments in parser table construction.
978 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
979 (generate_states): Don't mention ruleset, which is internal to closure.
980 * src/closure.c (closure): Explain sorting of core and itemset, which
981 is required for this function to behave correctly.
982 * src/closure.h (closure): Mention sorting.
984 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
986 * src/lalr.c (state_lookahead_tokens_count): For code readability,
987 move the check for disabled transitions to an aver since conflict
988 resolution hasn't happened yet.
990 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
991 labels a state as inconsistent just because it has error transitions.
992 The original form of this check appeared in revision 1.1 of lalr.c,
993 which was committed on 1991-12-21. Now (at least), changing the
994 consistency label on such a state appears to have no useful effect in
995 any of the places it is examined, which I enumerate below. The key
996 point to understanding each item in this enumeration is that a state
997 with an error transition is labelled consistent in the first place only
998 if it has no rules, so the check cannot matter for states that have
999 rules. (1) Labelling a state as inconsistent will cause set_conflicts
1000 to try to identify its conflicts, and a state must have *rules* to have
1001 conflicts. (2) Labelling a state as inconsistent will affect how
1002 action_row sets the default *rule* for the state. (3) Labelling a
1003 state as inconsistent will cause build_relations to add lookback edges
1004 to *rules* in that state.
1005 * src/state.h (struct state): Word the comment for member consistent
1008 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
1010 Don't depend on C99 features.
1011 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
1012 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
1013 * src/reader.c (check_and_convert_grammar): Fix for-loop.
1014 * src/state.c (state_mark_reachable_states): Fix for-loop.
1015 (state_remove_unreachable_states): Fix for-loop.
1017 Don't widen struct state with member reachable just to temporarily
1018 record reachability. Instead, use a local bitset.
1019 * src/state.h (struct state): Remove member.
1020 * src/state.c (state_new): Don't initialize it.
1021 (state_mark_reachable_states): Rename to...
1022 (state_record_reachable_states): ... this, and use bitset.
1023 (state_remove_unreachable_states): Use bitset.
1025 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
1027 * src/Makefile.am (yacc): Quote target action commands properly so
1028 that the yacc script isn't corrupt. Reported by Hans Aberg at
1029 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
1031 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
1032 the case of pure parsers. Reported by Frans Englich at
1033 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
1034 * THANKS: Add Frans Englich.
1036 * NEWS (2.3a+): In the %code entry, reference section `Bison
1037 Declaration Summary' from the manual now since the %code summary has
1039 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
1040 in the rules section must be terminated by semicolons.
1042 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
1044 Extend the front-end API for %define variables to more completely
1045 mirror the back-end. This will be useful in the future.
1046 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
1047 Update comments to mention the new front-end counterparts of these

1057 implementation more closely.
1058 (muscle_percent_define_invalid_value): New function.
1059 * src/muscle_tab.h (muscle_percent_define_get,
1060 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):

1065 * NEWS (2.3a+): Mention yesterday's state-removal change.
1066 (2.3a): Remove the %language entry, which was added after 2.3a.
1067 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
1068 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
1069 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
1070 tests/existing.at: Update copyright date.
1072 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1074 If conflict resolution makes states unreachable, remove those states,
1075 report rules that are then unused, and don't report conflicts in those

1092 an unused rule is discovered.
1094 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1096 Minor code cleanup in parser table construction.
1097 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
1098 (new_itemsets, save_reductions): Update for rename to nitemset.
1099 * src/closure.c (nritemset): Rename to...
1100 (nitemset): ... this since the "r" appears to meaningless and isn't
1101 used in the comments.
1102 (closure): Update for rename.
1103 * src/closure.h (nritemset): Update extern to...
1104 (nitemset): ... this.

1149 Rename method names according to previous patch.
1150 (Java Scanner Interface): Describe "%code lexer" instead of

1189 Make it easy to share %define boolean variables between the front-end
1190 and back-end. Though not used yet, this will be useful in the future.
1191 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
1192 Bison uses of names rather than just skeleton uses of names.
1193 (b4_percent_define_get, b4_percent_define_ifdef): Rename
1194 b4_percent_define_skeleton_variables(VARIABLE) to

1200 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
1201 muscle_percent_define_default): New functions mimicking
1202 b4_percent_define_flag_if and b4_percent_define_default.
1204 For %define variables, report locations for invalid values and
1206 * data/bison.m4 (b4_percent_define_flag_if): Read
1207 b4_percent_define_loc(VARIABLE) to report the location of an invalid
1209 (b4_percent_define_default): Save a special location in
1210 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE

1229 * src/print.c (lookahead_set, state_default_rule): Remove.
1230 (print_reductions): Replace state_default_rule invocation with

1233 (print_results): Don't allocate lookahead_set.
1235 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
1237 * data/lalr1.java: Prefix all private members with yy.
1239 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
1241 Use YYFPRINTF instead of fprintf where appropriate. Reported by
1242 Sebastien Fricker at

1259 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
1261 Undo my 2007-02-07 change, switching back to the c-strcase module
1262 introduced in the 2007-02-03 change. Bruno Haible reported that
1263 the 2007-02-07 change would be dangerous in Turkish if we add a
1264 language whose name contains "i", since "i" is not lowercase "I"
1266 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
1267 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
1268 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
1269 * m4/.cvsignore: Remove strcase.m4.
1270 * src/getargs.c: Revert 2007-02-07 change, as follows.
1271 Include c-strcase.h.
1272 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
1274 2007-02-11 Bruno Haible <bruno@clisp.org>
1276 Enable the Java related testsuite tests when the only Java compiler
1277 found is a gcj < 4.3. Discussed at
1278 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
1279 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
1281 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
1283 * data/Makefile.am: Update copyright date.
1284 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
1285 yypstate_new returns NULL.
1286 (yypstate_new): Return NULL if malloc does.
1287 * src/reader.c (packgram): Move translation of rule actions from the
1288 beginning of packgram to...
1289 (check_and_convert_grammar): ... here right before packgram is invoked
1290 so it's easier to write more complete comments, and remove redundant
1293 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
1295 As in semantic actions, make @$ in %initial-action, %destructor, and
1296 %printer imply %locations.
1297 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
1299 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
1300 (@$ in %initial-action implies %locations,
1301 @$ in %destructor implies %locations,
1302 @$ in %printer implies %locations): ... these new test cases.
1304 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
1306 Undo most of the 2007-02-03 change, switching to the strcase module
1307 now that gnulib strcase has been fixed.
1308 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
1309 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
1310 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
1311 * m4/.cvsignore: Add strcase.m4.
1312 * src/getargs.c: Revert 2007-02-03 change, as follows.
1313 Don't include c-strcase.h.
1314 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
1315 strcasecmp has "unspecified behavior" outside the POSIX locale,
1316 but it works fine in practice if at least one argument is ASCII,
1317 as is the case in Bison.
1319 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
1321 * tests/java.at: Skip tests if only one of javac/java is present.
1322 Reported by Joel E. Denny.
1323 * tests/atlocal.in: Adjust copyright years.
1325 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
1327 * data/lalr1.java (Stack): Work around old verifiers that disallow
1328 access to the private fields of an inner class, from the outer class.
1329 We can make Stack's fields public because user code doesn't have access
1330 to the instance of Stack used by parse(). Reported by Paul Eggert.
1332 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1334 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
1335 the right spot for these files?
1336 * bootstrap.conf (gnulib_modules): Add c-strcase.
1337 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
1339 * src/getargs.c: Include c-strcase.h.
1340 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
1341 to avoid unspecified behavior.
1343 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
1345 * doc/bison.texinfo (Decl Summary): Correct typo.
1347 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
1349 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
1350 Complain if the value does not match empty, "true" or "false".
1351 * data/c++.m4: Adjust default definitions of %define variables.
1352 * data/java.m4: Adjust default definitions of %define variables.
1353 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
1355 * tests/input.at (Boolean %define variables): Test new behavior.
1357 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
1359 * NEWS: Mention java.
1360 * TODO: Remove things that are done.
1361 * bootstrap.conf: Add javacomp-script and javaexec-script.
1362 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.

1365 * data/java-skel.m4: New.
1366 * data/java.m4: New.
1367 * data/lalr1.java: New.
1369 * doc/bison.texinfo: Put "A Complete C++ Example" under
1370 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
1371 under Other Languages.
1373 * src/getargs.c (valid_languages): Add Java.
1374 * src/getargs.h (struct bison_language): Update size of string fields.
1376 * tests/Makefile.am: Add java.at.
1377 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
1378 * tests/java.at: New.
1379 * tests/testsuite.at: Include it.
1381 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
1384 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
1385 at_directive_argv arguments so these no longer have to be global
1386 variables. Also, update the implementation for the following changes.
1387 (fail_for_at_directive_too_many_args,
1388 fail_for_at_directive_too_few_args): Add at_directive_name argument.
1389 (at_directive_name): Remove as at_directive_argv[0] will be used for
1391 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
1392 for the directive name.
1393 (at_directive_argc, at_directive_argv): Make these local within
1394 skel_lex instead of global.
1395 (INITIAL): Update directive start action for above changes.
1396 (SC_AT_DIRECTIVE_ARG): Rename to...
1397 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
1398 (SC_AT_DIRECTIVE_SKIP_WS): Update.
1399 (scan_skel): Move yylex_destroy to...
1400 (skel_scanner_free): ... here.
1401 * tests/skeletons.at (installed skeleton file name): Rename to...
1402 (installed skeleton file names): ... this.
1404 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
1406 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1407 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
1408 Summary" not "Directives".
1409 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
1410 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
1411 since the former is now the more complete one.
1412 (Prologue Alternatives): Likewise and do the same for %defines.
1413 (Table of Symbols): Add summary of %code, add summary of %define, and
1414 move full %code documentation to...
1415 (Decl Summary): ... here for consistency with other entries in these
1417 Move %define entry in order to keep this list alphabetized.
1418 Reword %define entry a little to put less emphasis on the skeleton
1419 concept, which most users shouldn't have to think about.
1421 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
1423 Adjust to recent gnulib changes.
1424 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
1425 Add string.h, string_.h, unistd_.h, wchar_.h.
1426 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
1427 * src/system.h: Don't include <stpcpy.h>; this is now done by
1430 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
1432 Simplify implementation of unqualified %code, implement macros for
1433 uniform treatment of boolean %define flags. Document %define.
1434 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
1435 b4_percent_code_ifdef): New.
1436 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
1437 * data/c++.m4: Define default value for global_tokens_and_yystype.
1438 * data/glr.cc: Likewise.
1439 * data/location.cc: Use b4_percent_define_flag_if.
1441 * doc/bison.texinfo (Decl Summary): Document %define.
1443 * src/parse-gram.y (Unqualified %code): Change muscle name to
1445 (content.opt): Default to empty.
1447 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1449 Implement support for relative and absolute skeleton file names.
1450 Discussed starting at
1451 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
1452 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
1453 (Bison Options): Document in --skeleton entry.
1454 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
1455 full_skeleton can't necessarily hold all of pkgdatadir.
1456 If the specified skeleton file name contains a `/', don't prepend
1458 * src/parse-gram.y (prologue_declaration): If the specified skeleton
1459 file name contains a `/', prepend the grammar file directory.
1460 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
1461 * skeletons.at: New file.
1462 (relative skeleton file names): New test case.
1463 (installed skeleton file names): New test case.
1464 * tests/testsuite.at: Include skeletons.at.
1466 * bootstrap: Update copyright to 2007.
1468 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
1470 * bootstrap: Remove occurrences of .#bootmp from the files.
1472 2007-01-17 Akim Demaille <akim@epita.fr>
1474 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
1476 Use per-type %printer.
1478 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1480 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

1488 2007-01-16 Akim Demaille <akim@epita.fr>
1490 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
1492 (Calc++ Scanner): Exit with failure if we can't open the input
1494 Accept "-" standing for stdin.
1495 (Calc++ Top Level): Print the result only if the parsing was
1498 2007-01-16 Akim Demaille <akim@epita.fr>
1500 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
1502 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
1503 and Joel E. Denny <jdenny@ces.clemson.edu>
1505 Clean up %define and %code implementation in M4 some. Most
1506 importantly, rename all related macros to be in the b4_percent_define
1507 and b4_percent_code namespaces. Also, complete support for `.' in
1508 %define variable names and %code qualifiers.
1509 * data/bison.m4 (b4_check_user_names): Check for special
1510 "SKELETON-NAMESPACE(name)" macros instead of using two nested
1512 (b4_get_percent_define, b4_get_percent_code): Rename to...
1513 (b4_percent_define_get, b4_percent_code_get): ... these.
1514 Extend documentation with examples.
1515 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
1516 b4_percent_define_skeleton_variables and
1517 b4_percent_code_skeleton_qualifiers.
1518 Expect any value for the %define variable `foo' to be stored in the
1519 macro named `b4_percent_define(foo)'; expect any %code blocks for the
1520 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
1521 expect any unqualified %code blocks to be stored in a macro named
1522 `b4_percent_code_unqualified'.
1523 Use m4_indir so that %define variable names and %code qualifiers can
1524 contain `.', which is allowed by the grammar parser.
1525 (b4_percent_define_default): New macro to set a default value for a
1527 (m4_wrap): Update wrapped code, and fix some underquoting.
1528 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
1529 Expect grammar uses of %define variables and %code qualifiers to be
1530 defined in b4_percent_define_user_variables and
1531 b4_percent_code_user_qualifiers.
1532 * data/c++.m4: Use b4_percent_define_default rather than
1533 m4_define_default. Fix some underquoting. Skeleton usage of %define
1534 variable define_location_comparison now implies skeleton usage of
1535 %define variable filename_type.
1536 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1537 data/push.c, data/yacc.c: Update macro names.
1538 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
1541 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
1543 DJGPP specific issues.
1545 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
1546 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
1548 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1550 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
1551 run parsers in all tests so that Valgrind is invoked during
1552 maintainer-check-valgrind.
1553 (Duplicate representation of merged trees): Free all semantic values.
1554 (Duplicated user destructor for lookahead): Likewise.
1556 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1558 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
1559 command-line prefix.
1560 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
1561 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
1562 miss Valgrind messages.
1563 (Exploding the Stack Size with Malloc): Likewise.
1565 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
1567 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
1568 locals. Reported by Juan Manuel Guerrero at
1569 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
1570 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
1571 Fix some indentation also.
1572 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
1573 explaining this issue.
1575 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
1576 and Joel E. Denny <jdenny@ces.clemson.edu>
1578 Simplify union and prologue handling, and escape union and lex/parse
1579 params with digraphs.
1580 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
1581 values to the empty string since these are no longer guaranteed
1582 initialized by the front-end.
1583 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
1584 braces around b4_user_stype since this is no longer done by the
1586 * src/files.c, src/files.h (pre_prologue_obstack,
1587 post_prologue_obstack): Remove.
1588 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
1589 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
1590 with digraphs. This fixes lex params and parse params.
1591 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
1592 * src/output.c (prepare): Remove muscle insertion of the prologues.
1593 (output): Remove freeing of pre_prologue_obstack and
1594 post_prologue_obstack.
1595 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
1596 than prologue_augment for prologue parsing so you don't need prologue
1598 (grammar_declaration): For %union RHS, use `braceless' instead of
1599 "{...}" so that braces are already stripped and code is escaped with
1601 * src/reader.c (prologue_augment): Remove.
1602 (reader): Remove initialization of pre_prologue_obstack and
1603 post_prologue_obstack.
1604 * src/reader.h (prologue_augment): Remove.
1606 * data/c.m4: Remove stray parenthesis.
1608 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1610 Remove quotes from variables names in %define directives and from
1611 qualifiers in %code directives, and restrict the characters that are
1612 allowed in them to M4-friendly ones. For %define, continue to support
1613 the quoted form as a deprecated feature. Discussed starting at
1614 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
1615 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
1617 * doc/bison.texinfo (Prologue Alternatives): Update.
1618 (Decl Summary): In %defines entry, update mention of `%code requires'
1619 and `%code provides'.
1620 (C++ Location Values): Update %define uses.
1621 (Calc++ Parser Interface): Likewise.
1622 (Calc++ Parser): Likewise, and update `%code requires' uses.
1623 (Table of Symbols): Update %code documentation.
1624 * src/parse-gram.y (prologue_declaration): For %define variables, use
1625 `variable' instead of `STRING'.
1626 (grammar_declaration): For %code qualifiers, use `ID' instead of
1628 (variable): New nonterminal that takes an `ID' or a `STRING'.
1629 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
1631 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
1632 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
1633 (%define errors): Update %define uses.
1635 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1637 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
1638 instead of muscle_insert for %define values so that M4-special
1639 characters are replaced with digraphs.
1640 * tests/input.at (%define errors): Extend to check weird values.
1642 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
1644 Instead of having skeletons declare all valid %define variables and
1645 %code qualifiers, provide macros that retrieve the associated values
1646 and build these lists automatically. Thus Bison will now warn when a
1647 variable or qualifier is not used by the skeleton in the current
1648 invocation regardless of whether it might sometimes be used by that
1649 skeleton in other invocations. Also, move all %define value macros to
1650 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
1651 form, which is replaced by %code.
1652 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
1653 (b4_check_user_names): ... this, and change the series of valid name
1654 arguments to a single list argument for names used in the skeleton
1655 similar to the existing list argument for names used in the grammar.
1656 Warn instead of complaining.
1657 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
1658 values and %code code, to format %code code properly, and to build
1659 lists of all %define variables and %code qualifiers used in the
1660 skeleton: b4_skeleton_percent_define_variables and
1661 b4_skeleton_percent_code_qualifiers.
1662 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
1664 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
1665 the skeleton names lists can finish building first. In place of
1666 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
1667 expect the lists b4_user_percent_define_variables and
1668 b4_user_percent_code_qualifiers.
1669 * data/c++.m4: Where setting default values for b4_parser_class_name,
1670 b4_location_type, b4_filename_type, b4_namespace, and
1671 b4_define_location_comparison, update their names to the
1672 b4_percent_define_ namespace.
1673 * data/glr.c: Don't use b4_check_percent_define_variables and
1674 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
1675 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
1676 (b4_parser_class_name, b4_namespace): Define these using
1677 b4_get_percent_define for parser_class_name and namespace.
1678 * data/location.cc: Use b4_get_percent_define.
1679 * data/push.c: Don't use b4_check_percent_define_variables and
1680 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
1681 * data/yacc.c: Likewise, and don't call m4_exit in
1682 b4_use_push_for_pull_if or m4_wrap code will never execute.
1683 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
1685 (muscle_grow_user_name_list): ... this for consistency with the
1686 terminology used in bison.m4.
1687 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
1688 %define variable names, and rename muscle used_percent_define_variables
1689 to user_percent_define_variables.
1690 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
1691 user_percent_code_qualifiers.
1693 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
1694 {CODE} form is no longer accepted.
1695 * tests/input.at (Reject bad %code qualifiers): Rename to...
1696 (Reject unused %code qualifiers): ... this, and update test output.
1697 (%define error): Update test output.
1699 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
1701 Check for unrecognized %define variables similar to checking for
1702 unrecognized %code qualifiers. Check for redefined %define variables.
1703 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
1705 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
1706 (b4_check_percent_define_variables): New, also wraps it.
1707 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
1708 variables using b4_check_percent_define_variables.
1709 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
1710 all those exercised in the test suite and all those listed in the
1711 `Default values' section of c++.m4. Are there others?
1712 * data/push.c, data/yacc.c: Declare no valid %define variables.
1713 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
1714 similar to muscle_find, but it works even when the muscle stores a
1716 (muscle_grow_used_name_list): New function for constructing the used
1717 name list muscles that b4_check_for_unrecognized_names requires.
1718 * src/parse-gram.y (prologue_declaration): Warn if a variable is
1719 %define'd more than once. Define the b4_used_percent_define_variables
1720 muscle with muscle_grow_used_name_list.
1721 (grammar_declaration): Abbreviate %code code with
1722 muscle_grow_used_name_list.
1723 * tests/input.at (%define errors): New.
1725 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
1727 Provide warn_at, complain_at, and fatal_at function callbacks to the
1728 skeletons, and use this for %code qualifier complaints.
1729 * data/bison.m4 (b4_error_at): New, invoked by...
1730 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
1731 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
1732 @fatal_at(...@) directives.
1733 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
1734 qualifiers in b4_used_percent_code_qualifiers and to use
1736 * src/location.c, src/location.h (boundary_set_from_string): New global
1738 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
1740 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
1741 to b4_used_percent_code_qualifiers.
1742 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
1744 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
1745 (lineno): Rename to...
1746 (out_lineno): ... this so I don't misunderstand it again.
1747 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
1748 here; these newlines are in the input but not the output file.
1749 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
1750 (at_directive_perform): ... this new static function, and add handling
1751 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
1753 * tests/input.at (Reject bad %code qualifiers): Update test output with
1754 locations and extend.
1756 * tests/output.at (Output file name: [, Output file name: ]): Remove
1757 bogus comment about these tests failing.
1759 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
1761 Clean up b4_check_percent_code_qualifiers a little.
1762 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
1763 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
1764 documentation and add examples.
1765 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
1768 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
1770 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
1771 unreliable -- especially when they're hidden inside another macro.
1772 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
1773 data/c.m4: Remove m4_divert(-1).
1774 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1775 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
1776 m4_divert_push(0) and m4_divert_pop(0).
1777 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
1778 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
1779 pushed and popped by m4sugar, should be first on the stack.
1781 Provide warn, complain, and fatal function callbacks to the skeletons.
1782 This provides more flexibility than m4_fatal, improves the error
1783 message format, and captures messages for translation. Discussed
1785 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
1786 * data/bison.m4 (b4_error): New, invoked by...
1787 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
1788 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
1789 directives. Because these M4 macros might be called when the current
1790 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
1791 the previous removal of uses of m4_divert, which caused trouble.
1792 (b4_check_percent_code_qualifiers): Use b4_complain instead of
1793 m4_fatal to report unrecognized %code qualifiers.
1794 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
1795 push parser requests.
1796 * data/glr.c: Use b4_complain instead of m4_fatal to report
1797 non-deterministic push parser requests.
1798 Update @output usage to @output(...@) form.
1799 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
1800 report missing %defines. Update @output usage to @output(...@) form.
1801 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
1803 * src/main.c (main): Invoke skel_scanner_free.
1804 * src/scan-skel.h (skel_scanner_free): Prototype new function.
1805 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
1806 obstack_for_string from flex-scanner.h.
1807 (YY_DECL): Use to declare skel_lex static.
1808 (decode_at_digraphs): Remove; now handled in the new
1809 SC_AT_DIRECTIVE_ARG start condition.
1810 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
1812 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
1813 at_directive_argv): New static globals.
1814 (INITIAL): Use fail_for_invalid_at.
1815 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
1816 recognize the start of a generalized `@directive(...@)' form and
1818 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
1819 directive args (using the new obstack_for_string), to decode the
1820 contained @ diagraphs, and to perform the directive. It recognizes
1821 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
1823 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
1824 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
1826 (scan_skel): Initialize obstack_for_string on the first call.
1827 (skel_scanner_free): New function to free obstack_for_string.
1828 * tests/input.at (Reject bad %code qualifiers): Update test output.
1830 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
1832 Consolidate the 4 prologue alternative directives (%code, %requires,
1833 %provides, and %code-top) into a single %code directive with an
1834 optional qualifier field. Discussed at
1835 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
1836 * NEWS (2.3a+): Rewrite the existing entry for the prologue
1838 * doc/bison.texinfo (Prologue Alternatives): Update.
1839 (Decl Summary): Update to %code "requires" and %code "provides".
1840 (Calc++ Parser): Update to %code "requires".
1841 (Table of Symbols): Remove entries for %requires, %provides, and
1842 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
1843 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
1844 are replaced by b4_percent_code_provides and b4_percent_code_requires,
1845 which are skeleton-specific.
1846 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
1847 declare what %code qualifiers it supports and to complain if any other
1848 qualifiers were used in the grammar.
1849 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
1850 and b4_user_code([b4_percent_code_provides]) in place of
1851 b4_user_requires and b4_user_provides.
1852 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
1853 Add b4_user_code([b4_percent_code_top]) and
1854 b4_user_code([b4_percent_code]).
1855 Invoke b4_check_percent_code_qualifiers.
1856 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
1857 PERCENT_REQUIRES): Remove.
1858 (grammar_declaration): Remove RHS's for %code-top, %provides, and
1859 %requires. Rewrite the %code RHS as the unqualified form defining the
1860 muscle b4_percent_code. Add another RHS for the qualified %code form,
1861 which defines muscles of the form b4_percent_code_QUALIFIER and the
1862 b4_used_percent_code_qualifiers muscle.
1863 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
1864 PERCENT_REQUIRES): Remove.
1865 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
1866 %code "requires" and %code "provides".
1867 * tests/input.at (Reject bad %code qualifiers): New.
1869 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
1871 Use the new code_props interface for destructors and printers.
1872 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
1873 printer_location members, and change the type of the destructor and
1874 printer members to code_props.
1875 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
1876 symbol_printer_get, semantic_type_destructor_set,
1877 semantic_type_printer_set, default_tagged_destructor_set,
1878 default_tagless_destructor_set, default_tagged_printer_set,
1879 default_tagless_printer_set): Use code_props in arguments and return
1880 types in place of char const * and location.
1881 (symbol_destructor_location_get, symbol_printer_location_get): Remove
1882 since the locations are now contained in the return of
1883 symbol_destructor_get and symbol_printer_get.
1884 * src/output.c (symbol_destructors_output, symbol_printers_output):
1886 (symbol_code_props_output): ... this to eliminate duplicate code.
1887 (output_skeleton): Update to use symbol_code_props_output.
1888 * src/reader.c (symbol_should_be_used): Update use of
1889 symbol_destructor_get.
1890 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
1891 Update uses of the various _destructor_set and _printer_set functions.
1892 * src/symtab.c: (default_tagged_destructor_location,
1893 default_tagless_destructor_location, default_tagged_printer_location,
1894 default_tagless_printer_location): Remove since we...
1895 (default_tagged_destructor, default_tagless_destructor,
1896 default_tagged_printer, default_tagless_printer): ... change the type
1897 of these to code_props.
1898 (symbol_new, semantic_type_new, symbol_destructor_set,
1899 semantic_type_destructor_set, symbol_destructor_get,
1900 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
1901 symbol_check_alias_consistency, default_tagged_destructor_set,
1902 default_tagless_destructor_set, default_tagged_printer_set,
1903 default_tagless_printer_set): Update.
1904 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
1905 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
1907 (symbol_print): Use SYMBOL_CODE_PRINT.
1909 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
1911 Use the new code_props interface for rule actions.
1912 * src/symlist.h (symbol_list): Replace action, action_location, and
1913 used members with a code_props action_props member.
1914 * src/reader.c (symbol_should_be_used, grammar_rule_check,
1915 grammar_midrule_action, grammar_current_rule_merge_set,
1916 grammar_current_rule_symbol_append, packgram): Update.
1917 * src/scan-code.h (translate_rule_action): Remove, no longer used.
1918 * src/scan-code.l (handle_action_dollar): Update.
1919 (translate_rule_action): Remove, no longer used.
1920 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
1922 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
1924 Use the new code_props interface in parse-gram.y.
1925 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
1926 Update all uses of translate_* functions to use the new code_props
1927 interface and to use gram_scanner_last_string_free and
1928 code_scanner_last_string_free where possible.
1929 (grammar_declaration): symbol_list_destructor_set and
1930 symbol_list_printer_set now perform the translation, so don't do it
1931 here. Use gram_scanner_last_string_free where possible.
1932 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
1933 translate_code): Remove, no longer used.
1934 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
1935 symbol_list_printer_set): Perform code translation here rather than
1936 depending on the caller to do so.
1938 * src/symlist.h (struct symbol_list): Correct some documentation typos.
1939 * src/scan-gram.h (gram_last_string): Remove declaration.
1940 * src/scan-gram.l (last_string): Declare it static.
1942 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
1944 Encapsulate code properties and related functionality for the various
1945 destructors, printers, and actions into a code_props structure and
1946 interface. This patch merely implements code_props in scan-code.h and
1947 scan-code.l. Future patches will rewrite other modules to use it.
1948 Discussed starting at
1949 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
1950 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
1951 consistently initialize const structs that have an empty location
1953 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
1954 to ensure consistency.
1955 * src/scan-code.h (code_props): New structure.
1956 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
1957 function, macro, and const global variable for initializing a
1958 code_props with no code.
1959 (code_props_plain_init, code_props_symbol_action_init,
1960 code_props_rule_action_init, code_props_translate_code): The rest of
1961 the new code_props functional interface. Among other things, the init
1962 functions set the code_props kind field so that
1963 code_props_translate_code will know whether to behave like
1964 translate_symbol_action, translate_rule_action, or translate_code.
1965 These old translate functions must remain until all other modules are
1966 updated to use the new code_props interface.
1967 (code_scanner_last_string_free): New function similar to
1968 gram_scanner_last_string_free.
1969 (code_scanner_free): Add documentation.
1970 * src/scan-code.l: Implement the new interface.
1971 (code_lex): Make it static, add a code_props* argument, and remove the
1973 (last_string): New static global similar to the one in scan-gram.l.
1974 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
1976 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
1977 code_props since Bison may one day use this information for destructors
1979 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
1980 (handle_action_dollar): Use symbol_list_n_get and set used flag
1981 directly since symbol_list_n_used_set is removed.
1982 (translate_action): Add a code_props* argument and remove the rule,
1983 action, and location arguments. Pass the code_props* on to code_lex.
1984 (translate_rule_action, translate_symbol_action, translate_code):
1985 Rewrite as wrappers around the new code_props interface.
1986 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
1987 it would eventually need to break the encapsulation of code_props.
1989 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
1991 * etc/.cvsignore: New.
1993 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
1995 Add maintainer-push-check to run maintainer-check using push parsing in
1996 place of pull parsing where available.
1997 * Makefile.am (maintainer-push-check): New.
1998 * data/bison.m4 (b4_use_push_for_pull_if): New.
1999 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
2000 appropriately based on their existing values.
2001 (yypush_parse): Don't print push-parser-specific diagnostics if push
2002 parsing is being used in place of pull parsing.
2003 * data/yacc.c: If push parsing should replace pull parsing, redirect to
2005 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
2006 variable, and insert b4_use_push_for_pull_flag into muscles.
2007 * tests/Makefile.am (maintainer-push-check): New.
2009 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2011 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
2012 (whether successful or failed) so that yypush_parse can be invoked
2013 again to start a new parse using the same yypstate.
2014 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
2015 check multiple yypull_parse invocations on the same yypstate. For pull
2016 mode, extend to check multiple yyparse invocations.
2017 (Exploding the Stack Size with Alloca): Extend to try with
2019 (Exploding the Stack Size with Malloc): Likewise.
2021 * tests/calc.at (Simple LALR Calculator): Don't specify
2022 %skeleton "push.c" since %push-pull-parser implies that now.
2023 * tests/headers.at (export YYLTYPE): Don't check for the push
2024 declarations. Otherwise, this test case can't be used to see if push
2025 mode can truly emulate pull mode.
2026 * tests/input.at (Torturing the Scanner): Likewise.
2027 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
2028 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
2029 AT_YACC_IF, which now includes the case of push mode since %skeleton
2030 need not be used for push mode. This will be more intuitive once
2031 push.c is renamed to yacc.c.
2033 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2035 For push mode, convert yyparse from a macro to a function, invoke yylex
2036 instead of passing a yylexp argument to yypull_parse, and don't
2037 generate yypull_parse or yyparse unless %push-pull-parser is declared.
2038 Discussed starting at
2039 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
2040 * data/bison.m4 (b4_pull_if): New.
2041 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
2042 * data/push.c: Improve M4 quoting a little.
2043 (b4_generate_macro_args, b4_parenthesize): Remove.
2044 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
2045 any time a pull parser is requested.
2046 Don't #define this as a wrapper around yypull_parse. Instead, when
2047 both push and pull are requested, make it a function that does that
2049 (yypull_parse): If there's a b4_prefix, #define this to
2050 b4_prefix[pull_parse] when both push and pull are requested.
2051 Don't define this as a function unless both push and pull are
2053 Remove the yylexp argument and hard-code yylex invocation instead.
2054 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
2056 * src/getargs.c (pull_parser): New global initialized to true.
2057 * getargs.h (pull_parser): extern it.
2058 * src/output.c (prepare): Insert pull_flag muscle.
2059 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
2060 (prologue_declaration): Set both push_parser and pull_parser = true for
2061 %push-pull-parser. Set push_parser = true and pull_parser = false for
2063 * src/scan-gram.l: Don't accept %push_parser as an alternative to
2064 %push-parser since there's no backward-compatibility concern here.
2065 Scan %push-pull-parser.
2066 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
2067 instead of %push-parser.
2068 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
2069 prototype it in the module that calls yyparse.
2070 * tests/input.at (Torturing the Scanner): Likewise.
2071 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
2073 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
2075 Update etc/bench.pl. Optimize push mode a little (the yyn change
2076 deserves most of the credit).
2077 * Makefile.am (SUBDIRS): Add etc subdirectory.
2078 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
2079 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
2080 yytoken, yyval, and yyloc declarations to...
2081 (yyparse or yypush_parse): ... here to improve performance. For
2082 yypush_parse invocations after the first, be sure to assign yyn its old
2084 (yypstate_new): Don't bother initializing the yyresult field since the
2085 initial value isn't used.
2086 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
2087 remove the #define that, in push mode, set it to yyps->NAME.
2088 * etc/Makefile.am: New.
2089 * etc/bench.pl: Remove and build it instead from...
2090 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
2091 "tests/bison" from the build directory by default rather than just
2092 invoking "bison" from $PATH.
2093 (calc_grammar): Update push parser code: don't declare yylval globally,
2094 don't define yyparse_wrapper, and don't #define yyparse.
2095 (bench_grammar): Update to check all working combinations of yacc.c,
2096 push.c, impure, pure, pull, and push.
2098 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2100 For push mode, add pull wrappers around yypush_parse.
2101 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
2102 (yypull_parse): New function wrapping yypush_parse.
2103 (yyparse): New #define wrapping yypull_parse.
2104 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
2106 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
2107 prototype yylex in the module that calls yyparse, and don't prototype
2108 yyparse there. Otherwise, the yyparse expansion won't compile.
2109 * tests/input.at (Torturing the Scanner): Likewise.
2111 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2113 Enable push parsers to operate in impure mode. Thus, %push-parser no
2114 longer implies %pure-parser. The point of this change is to move
2115 towards being able to test the push parser code by running the entire
2116 test suite as if %push-parser had been declared.
2117 * data/push.c (yypush_parse): For impure mode, remove the
2118 yypushed_char, yypushed_val, and yypushed_loc arguments.
2119 Instead, declare these as local variables initialized to the global
2120 yychar, yylval, and yylloc.
2121 For the first yypush_parse invocation only, restore the initial values
2122 of these global variables when it's time to read a token since they
2123 have been overwritten.
2124 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
2126 * tests/calc.at (Simple LALR(1) Calculator): Always declare
2127 %pure-parser along with %push-parser since this test case was designed
2128 for pure push parsers.
2129 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
2130 (AT_YACC_OR_PUSH_IF): New.
2131 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
2132 add a note that it's still wrong for some cases (as it has been for a
2134 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
2135 %push-parser no longer implies %pure-parser.
2137 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2139 Remove some unnecessary differences between the pull parser code and
2140 the push parser code. This patch enables yynerrs in push mode.
2141 * data/push.c: Reformat M4 a little.
2142 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
2143 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
2144 because push mode is on. Instead, if pure mode is on, move yynerrs
2146 (b4_declare_parser_state_variables): ... here.
2147 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
2148 to yyps->NAME so it can be used in yypush_parse.
2149 (yypush_parse): Don't omit uses of yynerrs in push mode.
2151 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2153 Fix bug such that the first pushed token's value and location are
2154 sometimes overwritten (sometimes by %initial-action) before being used.
2155 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
2156 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
2157 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
2158 more closely mimic the pull parser logic.
2159 Don't copy the pushed token to yychar, yylval, and yylloc until it's
2160 time to read a token, which is after any initialization of yylval and
2162 (gottoken): Rename label to...
2163 (yyread_pushed_token): ... for clarity and to avoid infringing on the
2166 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2168 Rearrange initialization of the parser state variables so that the
2169 skeleton doesn't have to have a copy for pull mode and another for push
2170 mode. This patch also fixes at least a bug such that yylloc was not
2171 initialized (with b4_location_initial_line and
2172 b4_location_initial_column) upon calling yypush_parse. However, that
2173 initialization now overwrites the first token's location;
2174 %initial-action assigning @$ already did the same thing, and both bugs
2175 will be fixed in a later patch.
2176 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
2177 (b4_declare_parser_state_variables): Remove initialization of yytoken,
2178 yyss, yyvs, yyls, and yystacksize.
2179 (yypstate_new): Remove initialization of some yypstate fields: yystate,
2180 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
2182 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
2183 yyps->NAME so it can be used in yypush_parse.
2184 (yyparse or yypush_parse): For yypush_parse, don't print the
2185 "Starting parse" diagnostic for invocations after the first.
2186 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
2187 yypush_parse, only do it for the first invocation.
2188 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
2189 initialization to occur in yypush_parse but only on the first
2192 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2194 * data/push.c: Add CPP guards around push parser declarations in both
2195 the header and the code file.
2196 In the code file, move the push parser declarations to the same place
2197 they appear in the header file.
2198 Clean up the M4 some, especially the inconsistent underquoting in
2199 some b4_c_function_def and b4_c_function_decl uses.
2201 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2203 Encapsulate the push parser state variables into an M4 macro so the
2204 push skeleton doesn't have to list them again for pull mode's yyparse.
2205 For push mode, remove yypush_parse's local equivalents of these
2206 variables to eliminate unnecessary copying between the two sets at
2207 run-time. This patch also fixes at least a bug related to multiple
2208 %initial-action invocations in push mode.
2209 * data/push.c (b4_declare_parser_variables): Rename to...
2210 (b4_declare_scanner_communication_variables): ... this for clarity and
2212 (b4_declare_yyparse_variables): Remove and move its contents to the one
2213 spot where it was invoked.
2214 (b4_declare_parser_state_variables): New macro containing the parser
2215 state variables required by push mode.
2216 (struct yypstate): Replace all fields but yynew with
2217 b4_declare_parser_state_variables.
2218 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
2219 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
2220 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
2221 (yyparse or yypush_parse): For yyparse in pull mode, replace local
2222 parser state variable declarations with
2223 b4_declare_parser_state_variables.
2224 Don't initialize parser state variables when calling yypush_parse since
2225 yypstate_new already does that.
2226 Invoke the user's initial action only upon the first yypush_parse
2228 Remove all code that copies between the local parser state variables
2231 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2233 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
2234 prevent a name collision in a future patch where these names will
2235 sometimes be #define'd.
2236 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
2237 since it no longer has the same name as the existing argument.
2238 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
2240 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
2241 and Joel E. Denny <jdenny@ces.clemson.edu>
2243 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
2244 that the argument is case-insensitive, and there's no `=' here.
2245 For the %skeleton entry, mention that %language is better.
2246 (Bison Options): Likewise for --language and --skeleton. Move the
2247 --skeleton entry so that the `Tuning the parser' section is sorted
2248 alphabetically on long options.
2249 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
2250 %language directive in detail here; cross-reference the %language
2251 documentation instead.
2252 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
2253 `%require "2.3b"' so that the example is always up-to-date.
2254 (Table of Symbols): Add entries for %language and %skeleton.
2255 * examples/extexi (normalize): Instead of replacing every %require
2256 argument with the current Bison version, just substitute for
2257 `@value{VERSION}'. This guarantees that we're testing what actually
2258 appears in the documentation.
2259 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
2260 rather than `@VERSION@'.
2262 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2264 * NEWS: Reword the %language news a bit, and put it earlier.
2266 * src/getargs.c (skeleton_arg): Last arg is now location const *.
2267 Rewrite to simplify the logic.
2268 (language_argmatch): Likewise.
2269 (program_name): We now own this var.
2270 * src/getargs.h (struct bison_language): Use char[] rather than
2273 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
2275 * src/complain.c (program_name): Remove decl; no longer needed.
2276 * src/main.c (program_name): Remove; now belongs to getargs.
2278 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
2280 * NEWS: Document %language.
2282 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
2284 * data/c-skel.m4, data/c++-skel.m4: New files.
2285 * data/glr.c: Complain on push parsers.
2287 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
2289 (Decl Summary): Document %language and %skeleton.
2290 (Command line): Document -L.
2292 * examples/extexi: Rewrite %require directive.
2293 * examples/calc++/Makefile.am: Pass VERSION to extexi.
2295 * src/files.c (compute_exts_from_gc): Look in language structure
2297 (compute_file_name_parts): Check whether .tab should be added.
2298 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
2299 (language, skeleton_arg, language_argmatch): New.
2300 (long_options): Add --language.
2301 (getargs): Use skeleton_arg, add -L/--language.
2302 * src/getargs.h: Include location.h.
2303 (struct bison_language, language, skeleton_arg, language_argmatch): New.
2304 * src/output.c (prepare): Pick default skeleton from struct language.
2305 Don't dispatch C skeletons here.
2306 * src/parse-gram.y (PERCENT_LANGUAGE): New.
2307 (prologue_declaration): Add "%language" rule, use skeleton_arg.
2308 * src/scan-gram.l ("%language"): New rule.
2310 * tests/calc.at: Test %skeleton and %language.
2311 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
2312 (AT_GLR_IF): Look for %skeleton "glr.cc".
2313 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
2314 (AT_YACC_IF): Reject %language.
2316 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2318 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
2319 since it wasn't used; only the typedef name 'semantic_type' is needed.
2320 Also, omit trailing white space.
2322 * bootstrap: Sync from coreutils.
2323 (gnulib_extra_files): Add build-aux/announce.gen.
2324 (slurp): Adjust .gitignore files like .cvsignore files.
2325 * build-aux/announce-gen: Remove from CVS, since bootstrap
2328 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
2330 Make %push-parser imply %pure-parser. This fixes several bugs; see
2331 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
2332 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
2334 * data/push.c: Don't bother testing b4_push_if when deciding whether
2335 to expand b4_declare_parser_variables globally.
2336 (yypush_parse): Likewise in here.
2338 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
2339 (yy_reduce_print): Reformat M4 for readability.
2341 2006-12-15 Bob Rossi <bob@brasko.net>
2342 and Joel Denny <jdenny@ces.clemson.edu>
2344 * data/push.c (yypstate): Add typedef, and update all uses of
2345 struct yypstate to just yypstate.
2346 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
2348 2006-12-14 Bob Rossi <bob@brasko.net>
2350 * data/push.c (yypush_parse): Declare prototype regardless of
2353 2006-12-14 Bob Rossi <bob@brasko.net>
2355 * data/push.c (yyparse): Remove the prototype and the #define when in
2358 2006-12-13 Bob Rossi <bob@brasko.net>
2360 * data/push.c (yypstate_init): Rename to...
2361 (yypstate_new): ... this and use b4_c_function_def.
2362 (yypstate_delete): New.
2363 (yypush_parse): Change parameters yynval and yynlloc to be const.
2364 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
2365 yypstate_delete functions.
2367 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
2369 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
2370 strange test case titles. Reported by Bob Rossi.
2372 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
2374 * TODO: Add pointer to Sylvain Schmitz's work on static detection
2375 of potential ambiguities in GLR grammers.
2377 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
2379 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
2380 `bison ', use m4_index instead of m4_substr since chopping up a string
2381 containing M4-special characters causes problems here.
2383 Fix a couple of bugs related to special characters in user-specified
2384 file names, and make it easier for skeletons to compute output file
2385 names with the same file name prefix as Bison-computed output file
2387 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
2388 b4_parser_file_name and b4_spec_defines_file instead of
2389 @output_parser_name@ and @output_header_name@, which are now redundant.
2390 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
2391 b4_parser_file_name, b4_spec_defines_file, and the new
2392 @basename(FILENAME@) instead of @output_parser_name@ and
2393 @output_header_name@, which inappropriately escaped the file names as
2395 * src/files.c (all_but_ext): Remove static qualifier.
2396 (compute_output_file_names): Move `free (all_but_ext)' to...
2397 (output_file_names_free): ... here since all_but_ext is needed later.
2398 * src/files.h (all_but_ext): Extern.
2399 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
2400 exactly what MUSCLE_INSERT_STRING used to do.
2401 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
2402 characters are escaped properly.
2403 * src/output.c (prepare): Define muscle file_name_all_but_ext as
2405 For pkgdatadir muscle, maintain previous functionality by using
2406 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
2407 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
2408 digraphs would never be expanded. Hopefully no one has M4-special
2409 characters in his Bison installation path.
2410 * src/scan-skel.l: Don't parse @output_header_name@ and
2411 @output_parser_name@ anymore since they're now redundant.
2412 In @output, use decode_at_digraphs.
2413 Parse a new @basename command that invokes last_component.
2414 (decode_at_digraphs): New.
2415 (BASE_QPUTS): Remove unused.
2416 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
2417 (Output file name): New tests.
2419 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
2421 Warn about output files that are generated by the skeletons and that
2422 conflict with other output files.
2423 * data/glr.c: Don't generate the header file here when glr.cc does.
2424 * src/files.c (file_names, file_names_count): New static globals.
2425 (compute_output_file_names): Invoke output_file_name_check for files
2426 not generated by the skeletons and remove existing checks.
2427 (output_file_name_check): New function that warns about conflicting
2429 (output_file_names_free): Free file_names.
2430 * src/files.h (output_file_name_check): Declare.
2431 * src/scan-skel.l: Invoke output_file_name_check for files generated by
2433 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
2434 (Conflicting output files): New tests.
2436 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2438 * doc/bison.texinfo: Fix a couple of typos.
2440 2006-12-08 Bob Rossi <bob@brasko.net>
2442 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
2444 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
2446 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
2447 (yypush_parse): Rename yypvars argument to yyps and remove redundant
2449 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
2450 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
2452 2006-12-07 Bob Rossi <bob@brasko.net>
2453 and Joel Denny <jdenny@ces.clemson.edu>
2455 * data/push.c (yypvarsinit): Change return type from void* to struct
2456 yypvars*. No longer cast to void* on return.
2457 (struct yypvars): Remove yylen since it need not be remembered between
2458 yypushparse invocations.
2459 (yypushparse): Don't copy between yylen and pv->yylen.
2461 2006-12-05 Bob Rossi <bob@brasko.net>
2463 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
2464 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
2465 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
2466 (struct yypvars): Remove b4_declare_parser_variables.
2467 (yypvarsinit): Remove init code for removed variables.
2468 (global scope): Do not declare b4_declare_parser_variables if
2470 (yypushparse): Add b4_declare_parser_variables.
2471 Init new local variables, and remove init code for removed
2474 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
2475 and yyparse for other modes.
2476 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
2477 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
2478 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
2479 (AT_PURE_LEX_IF): True if pure or push parser.
2481 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
2483 Document Yacc prologue alternatives and default %destructor's and
2484 %printer's as experimental. Don't mention Java yet. Discussed at
2485 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
2486 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
2487 (2.3a): Annotate this entry to say the old forms of these features were
2489 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,

2498 * NEWS (2.3a+): Mention.
2499 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
2500 form of %defines, and remove `=' from entries for %file-prefix,
2501 %name-prefix, and %output.
2502 * src/parse-gram.y (prologue_declaration): Implement.
2503 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
2504 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
2505 all but one occurrence of %name-prefix.
2506 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
2507 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
2508 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
2509 occurrence of each of %file-prefix and %output. Add check for %defines
2511 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
2512 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
2513 Remove the `=' from %output.
2515 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
2517 Don't escape $ in test case titles since Autoconf 2.61 now does that
2519 * tests/actions.at (Default %printer and %destructor are not for error
2520 or $undefined): Here.
2521 (Default %printer and %destructor are not for $accept): Here.
2522 * tests/input.at (Invalid $n and @n): Here.
2524 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
2526 Rename <!> to <>. Discussed starting at
2527 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
2528 * NEWS (2.3a+): Update.

2534 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
2536 * tests/actions.at (Default tagless %printer and %destructor,
2537 Default tagged and per-type %printer and %destructor,
2538 Default %printer and %destructor are not for error or $undefined,
2539 Default %printer and %destructor are not for $accept,
2540 Default %printer and %destructor for mid-rule values): Update.
2541 * tests/input.at (Default %printer and %destructor redeclared,
2542 Unused values with default %destructor): Update.
2544 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
2546 Don't let %prec take a nonterminal.
2547 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
2549 * tests/input.at (%prec takes a token): New test checking that %prec
2550 won't take a nonterminal.
2552 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
2554 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
2555 it was double-quoted.
2556 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
2557 grammar is maintained with Bison's highest standards.
2558 * src/getargs.c: Fix some typos in Doxygen comments.
2560 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
2562 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
2563 later. Reported by Paul Eggert in
2564 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
2565 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
2566 * src/scan-code.l (translate_action): Don't bother invoking
2567 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
2568 (code_scanner_free): Instead of invoking
2569 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
2571 * src/scan-gram.l (gram_scanner_free): Likewise.
2572 * src/scan-skel.l (scan_skel): Likewise.
2574 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
2576 * src/files.c (tr): Change return type to void.
2577 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
2578 has been called previously for the same key.
2579 (muscle_find): Return storage instead of value so that
2580 --enable-gcc-warnings doesn't produce warnings that the return discards
2581 const. aver that the value and storage are the same since storage
2582 could potentially be NULL when value is not.
2583 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
2586 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2588 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
2589 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
2590 us a slightly cleaner distribution, and also works.
2591 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
2594 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
2595 and Paul Eggert <eggert@cs.ucla.edu>
2597 Don't let Bison leak memory except when it complains.
2598 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
2599 (spec_defines_file, dir_prefix): Now char *, not const char *,
2600 since they are freed.
2601 * src/files.c: Likewise.
2602 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
2604 (tr): Now operates in-place. All uses changed.
2605 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
2607 (compute_file_name_parts, compute_output_file_names): Don't store
2608 read-only data in variables that will be freed.
2609 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
2610 src_extension, and header_extension.
2611 (output_file_names_free): New public function to free
2612 spec_verbose_file, spec_graph_file, spec_defines_file,
2613 parser_file_name, and dir_prefix.
2614 * src/getargs.c (getargs): Don't store read-only data in variables that
2616 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
2617 (which previously existed but was unused), and quotearg_free.
2618 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
2619 * src/muscle_tab.c: Likewise.
2620 (muscle_entry): Make the value char const *,
2621 and add a new storage member that is char * and can be freed.
2622 (muscle_entry_free): New private function.
2623 (muscle_init): Use it instead of free.
2624 (muscle_insert, muscle_grow): Update and use new storage member.
2625 (muscle_code_grow): Free the string passed to muscle_grow
2626 since it's not needed anymore.
2627 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
2628 add a new `char *code' member.
2629 ("{...}"): Declare semantic type as code.
2630 * src/scan-code.h (translate_rule_action):
2631 (translate_symbol_action, translate_code, translate_action): Return
2632 `char const *' rather than `char *' since external code should not free
2634 * src/scan-code.l: Likewise.
2635 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
2636 which is "{...}" in the parser.
2637 * tests/Makefile.am (maintainer-check-valgrind): Set
2638 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
2640 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
2642 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
2643 expecting a non-zero exit status sets --leak-check=summary and
2644 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
2645 this case, and we don't want to hear about it.
2647 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2649 * bootstrap (runtime-po/Makevars): Derive from po/Makevars

2902 * bootstrap (usage, main program, symlink_to_gnulib): Add option
2903 --copy. Inspired by a suggestion from Bruno Haible.
2905 2006-10-03 Jim Meyering <jim@meyering.net>

2910 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2912 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

3108 not from $abs_top_builddir, since config.h moved.
3111 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
3112 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
3114 * src/parse-gram.y (symbol_declaration): Don't put statements
3115 before declarations; it's not portable to C89.
3116 * src/scan-code.l (handle_action_at): Likewise.
3118 * src/scan-code.l: Always initialize braces_level; the old code
3119 left it uninitialized and therefore had undefined behavior.
3121 Don't attempt to redefine 'assert', since it runs afoul of
3122 systems where standard headers (mistakenly) include <assert.h>.
3123 Instead, define and use our own alternative, called 'aver'.
3124 * src/reader.c: Don't include assert.h, since we no longer
3126 * src/scan-code.l: Likewise.
3127 * src/system.h (assert): Remove, replacing with....
3128 (aver): New function, taking a bool arg. All uses changed.
3129 * src/tables.c (pack_vector): Ensure that aver arg is bool,
3130 not merely an integer.
3132 2006-09-15 Bob Rossi <bob@brasko.net>
3134 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
3135 * data/c.m4 (YYPUSH): New.
3136 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
3137 * src/getargs.c (push_parser): New var.
3138 * src/getargs.h (push_parser): New declaration.
3139 * src/output.c (prepare): Add macro insertion of `push_flag'.
3140 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
3141 (prologue_declaration): Parse %push-parser.
3142 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
3143 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
3144 list of removed lines from the traces observed.
3145 (AT_CHECK_CALC_LALR): Added push parser tests.
3147 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
3149 * NEWS: Version 2.3a.
3150 * configure.ac (AC_INIT): Likewise.
3152 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
3153 "#define YYSTYPE int" that caused "make maintainer-check" to fail
3154 due to header ordering dependencies. I don't know why the #define
3157 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
3158 runtime cost when YYDEBUG is not defined, and so that some tests
3159 that used to fail now work. Problem and initial suggestion by
3161 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
3162 * data/glr.cc (b4_parser_class_name):
3163 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
3164 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
3165 (yydebug_) [YYDEBUG]: New member.
3166 (yycdebug_): Now defined only if YYDEBUG.
3167 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
3168 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
3169 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
3171 (debug_stream, set_debug_stream, debug_level, set_debug_level):
3172 Define only if YYDEBUG.
3173 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
3175 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
3176 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
3177 AT_CHECK_CALC_GLR_CC that are working now.
3179 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
3181 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
3182 We don't need them in glr.cc, and glr.c defines them.
3183 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
3184 assumes that defining it to anything is the same as defining
3185 it to 1. Problem reported by Paolo Bonzini.
3187 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
3189 * data/c.m4 (b4_null, b4_case): Define.
3190 * src/output.c (prepare_symbols): Use b4_null.
3191 (user_actions_output): Use b4_case.
3193 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
3195 * data/glr.c (b4_shared_declarations): Put start-header first,
3196 before any #includes that we generate, so that feature-test
3197 macros work. Problem reported by Michael Deutschmann in
3198 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
3199 * data/lalr1.cc: Likewise.
3200 * doc/bison.texinfo (Prologue): Document that feature-test macros
3201 should be defined before any Bison declarations.
3202 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
3203 that depend on location.hh after, not before, Bison decls, since
3204 we now include location.hh after the first user prologue.
3206 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
3207 Sander Brandenburg in
3208 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
3209 Also, fix minor white space and comment issues.
3210 (Prologue): Mention that it's better to define feature-test macros
3211 before Bison declarations. Problem reported by Michael Deutschmann.
3213 * README-cvs: Fix typo: "&" should be "&&". Problem reported
3215 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
3216 This adjusts to recent gnulib changes.
3218 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3220 Finish implementation of per-type %destructor/%printer. Discussed
3222 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
3224 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
3225 * NEWS (2.3+): Add a description of this feature to the default
3226 %destructor/%printer description.
3227 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
3228 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3229 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
3230 list node contains a semantic type.
3231 * src/symtab.c, src/symtab.h: Extend with a table that associates
3232 semantic types with their %destructor's and %printer's.
3233 (semantic_type_from_uniqstr, semantic_type_get,
3234 semantic_type_destructor_set, semantic_type_printer_set): New functions
3235 composing the public interface of that table.
3236 (symbol_destructor_get, symbol_destructor_location_get,
3237 symbol_printer_get, symbol_printer_location_get): If there's no
3238 per-symbol %destructor/%printer, look up the per-type before trying
3240 * tests/actions.at (Per-type %printer and %destructor): New test case.
3241 * tests/input.at (Default %printer and %destructor redeclared):
3242 Extend to check that multiple occurrences of %symbol-default in a
3243 single %destructor/%printer declaration is an error.
3244 (Per-type %printer and %destructor redeclared, Unused values with
3245 per-type %destructor): New test cases.
3247 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3249 Require default %destructor/%printer to be declared using
3250 %symbol-default instead of an empty symbol list, and start working on
3251 new per-type %destructor/%printer. Discussed at
3252 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
3253 * NEWS (2.3+): Add %symbol-default to example.
3254 * bison.texinfo (Freeing Discarded Symbols): Likewise.
3255 (Table of Symbols): Add entry for %symbol-default.
3256 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
3257 (generic_symlist, generic_symlist_item): New nonterminals for creating
3258 a list in which each item is a symbol, semantic type, or
3260 (grammar_declaration): Use generic_symlist in %destructor and %printer
3261 declarations instead of symbols.1 or an empty list.
3262 (symbol_declaration, precedence_declaration, symbols.1): Update actions
3263 for changes to symbol_list.
3264 * src/reader.c: Update for changes to symbol_list.
3265 * src/scan-code.l: Likewise.
3266 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
3267 * src/symlist.c, src/symlist.h: Extend such that a list node may
3268 represent a semantic type or a %symbol-default in addition to just an
3269 ordinary symbol. Add switched functions for setting %destructor's and
3271 * tests/actions.at, tests/input.at: Add %symbol-default to all default
3272 %destructor/%printer declarations.
3274 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
3276 Whether the default %destructor/%printer applies to a particular symbol
3277 isn't a question of whether the user *declares* that symbol (in %token,
3278 for example). It's a question of whether the user by any means
3279 *defines* the symbol at all (by simply using a char token, for
3280 example). $end is defined by Bison whereas any other token with token
3281 number 0 is defined by the user. The error token is always defined by
3282 Bison regardless of whether the user declares it with %token, but we
3283 may one day let the user define error as a nonterminal instead.
3284 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
3285 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
3286 the meaning of "user-defined".
3287 * tests/actions.at (Default %printer and %destructor for user-declared
3288 end token): Rename to...
3289 (Default %printer and %destructor for user-defined end token): ...
3292 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
3293 computation of whether to apply the default, don't maintain a list of
3294 every Bison-defined symbol. Instead, just check for a first character
3295 of '$', which a user symbol cannot have, and check for the error token.
3297 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
3299 Don't apply the default %destructor or %printer to the error token,
3300 $undefined, or $accept. This change fits the general rule that the
3301 default %destructor and %printer are only for user-declared symbols,
3302 and it solves several difficulties that are described in the new test
3304 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
3305 * tests/actions.at (Default %printer and %destructor are not for error
3306 or $undefined, Default %printer and %destructor are not for $accept):
3309 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
3311 Allow %start after the first rule.
3312 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
3313 when parsing the first rule.
3314 (check_and_convert_grammar): Search for it here after all grammar
3315 declarations have been parsed. Skip midrules, which have dummy LHS
3317 * src/symtab.c (symbol_is_dummy): New function.
3318 * src/symtab.h (symbol_is_dummy): Declare it.
3319 * tests/input.at (%start after first rule): New test.
3321 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3323 Redo some of the previous commit: add back the ability to use
3324 non-aliased/undeclared string literals since it might be useful to
3325 those declaring %token-table.
3326 * src/reader.c (check_and_convert_grammar): Undo changes in previous
3327 commit: don't worry about complaints from symbols_pack.
3328 * src/symtab.c (symbol_new, symbol_class_set,
3329 symbol_check_alias_consistency): Undo changes in previous commit: count
3330 each string literal as a new symbol and token, assign it a symbol
3331 number, and don't complain about non-aliased string literals.
3332 (symbols_pack): Since symbol_make_alias still does not decrement symbol
3333 and token counts but does still set aliased tokens to the same number,
3334 symbol_pack_processor now leaves empty slots in the symbols array.
3336 * tests/regression.at (Undeclared string literal): Remove test case
3337 added in previous commit since non-aliased string literals are allowed
3339 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
3340 remove unnecessary string literal declarations.
3341 * tests/sets.at (Firsts): Likewise.
3343 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3345 Don't allow an undeclared string literal, but allow a string literal to
3346 be used before its declaration.
3347 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
3348 symbols_pack complained.
3349 * src/symtab.c (symbol_new): Don't count a string literal as a new
3351 (symbol_class_set): Don't count a string literal as a new token, and
3352 don't assign it a symbol number since symbol_make_alias does that.
3353 (symbol_make_alias): It's not necessary to decrement the symbol and
3354 token counts anymore. Don't assume that an alias declaration occurs
3355 before any uses of the identifier or string, and thus don't assert that
3356 one of them has the highest symbol number so far.
3357 (symbol_check_alias_consistency): Complain if there's a string literal
3358 that wasn't declared as an alias.
3359 (symbols_pack): Bail if symbol_check_alias_consistency failed since
3360 symbol_pack asserts that every token has been assigned a symbol number
3361 although undeclared string literals have not.
3362 * tests/regression.at (String alias declared after use, Undeclared
3363 string literal): New test cases.
3364 (Characters Escapes, Web2c Actions): Declare string literals as
3366 * tests/sets.at (Firsts): Likewise.
3368 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
3370 In the grammar scanner, STRING_FINISH unclosed constructs and return
3371 them to the parser in order to improve error messages.
3372 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
3373 SC_BRACED_CODE, SC_PROLOGUE): Implement.
3374 * tests/input.at (Unclosed constructs): New test case.
3375 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
3378 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
3381 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
3383 Handle string aliases for character tokens correctly.
3384 * src/symtab.c (symbol_user_token_number_set): If the token has an
3385 alias, check and set its alias's user token number instead of its own,
3386 which is set to indicate the alias. Previously, every occurrence of
3387 the character token in the grammar overwrote that alias indicator with
3389 * tests/input.at (String aliases for character tokens): New test.
3391 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
3393 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
3395 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
3397 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
3398 to prevent failures when building on older platforms.
3399 Check for autopoint failure.
3400 Set XGETTEXT_OPTIONS to values that check for C format strings,
3401 so that translators are warned about them (this also helps
3402 prevent core dumps).
3404 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
3405 function, since it simplifies our code a bit.
3407 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
3408 rather than -W, so we don't get bogus warnings about sign comparisons.
3409 Add -Wpointer-arith, since that warning is useful (it reports code
3410 that does not conform to C89 and that some compilers reject).
3411 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
3412 since it's no longer needed.
3414 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
3416 Clean up scanners a bit.
3417 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
3418 definitions so gcc won't warn when obstack_for_string is unused.
3419 * src/scan-code.l: config.h and system.h are already #include'd by
3420 scan-code-c.c, so get rid of them here.
3421 * src/scan-gram.l: Likewise.
3422 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
3423 definitions rather than duplicating the rest of it.
3424 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
3426 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
3428 Suppress signed/unsigned comparison warnings for yycheck.
3429 * data/c.m4 (b4_safest_int_type): New macro.
3430 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
3431 a signed int type, cast it to b4_safest_int_type first.
3432 * data/yacc.c: Likewise.
3433 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
3436 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
3438 * doc/bison.texinfo: Fix some typos.
3440 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
3442 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
3443 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
3445 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
3446 the latest gnulib does this a different way.
3447 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
3448 translation was patched, so stop omitting it.
3450 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3452 Enable declaration of default %printer/%destructor. Make the parser
3453 use these for all user-declared grammar symbols for which the user does
3454 not declare a specific %printer/%destructor. Thus, the parser uses it
3455 for token 0 if the user declares it but not if Bison generates it as
3456 $end. Discussed starting at
3457 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
3458 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
3460 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
3461 * NEWS (2.3+): Mention.
3462 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
3463 declare a %destructor for a mid-rule's semantic value. It's just
3464 impossible to declare one specific to it.
3465 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
3466 code. Describe default %destructor form.
3467 * src/parse-gram.y (grammar_declaration): Parse default
3468 %printer/%destructor declarations.
3469 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
3470 and symbol_destructor_location_get rather than accessing the destructor
3471 and destructor_location members of struct symbol.
3472 (symbol_printers_output): Likewise but for %printer's.
3473 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
3475 * src/symtab.c (default_destructor, default_destructor_location,
3476 default_printer, default_printer_location): New static global
3477 variables to record the default %destructor and %printer.
3478 (symbol_destructor_get, symbol_destructor_location_get,
3479 symbol_printer_get, symbol_printer_location_get): New functions to
3480 compute the appropriate %destructor and %printer for a symbol.
3481 (default_destructor_set, default_printer_set): New functions to set the
3482 default %destructor and %printer.
3483 * src/symtab.h: Prototype all those new functions.
3484 * tests/actions.at (Default %printer and %destructor): New test to
3485 check that the right %printer and %destructor are called, that they're
3486 not called for $end, and that $$ and @$ work correctly.
3487 (Default %printer and %destructor for user-declared end token): New
3488 test to check that the default %printer and %destructor are called for
3489 a user-declared end token.
3490 * tests/input.at (Default %printer and %destructor redeclared, Unused
3491 values with default %destructor): New tests to check related grammar
3492 warnings and errors.
3494 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3496 Clean up handling of %destructor for the end token (token 0).
3497 Discussed starting at
3498 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
3500 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
3502 Make the skeletons consistent in how they pop the end token and invoke
3504 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
3505 state, which has token number 0, since this would invoke the
3506 %destructor for the end token.
3507 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
3508 until after shifting the end token, or else it won't be popped.
3509 * data/yacc.c (yyparse): Likewise.
3511 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
3512 it's the end token. Upon termination, destroy an unshifted lookahead
3513 even when it's the end token.
3514 * data/lalr1.cc (yy::parser::parse): Likewise.
3515 * data/yacc.c (yyparse): Likewise.
3517 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
3518 value warnings for the end token when the user gives the end token a
3521 * tests/actions.at (Printers and Destructors): Test all the above.
3523 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
3525 Update to latest gnulib and gettext versions.
3526 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
3528 (gnulib_files): Add m4/warning.m4. Don't worry about files
3529 overwritten by autopoint.
3530 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
3531 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
3533 Don't use autoreconf; instead, invoke autopoint etc. by hand,
3534 so that we can remove the intl files at a better time.
3535 (intl_files_to_remove): Remove aclocal.m4, since it gets
3536 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
3537 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
3538 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
3539 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
3540 Remove datarootdir hack; no longer needed.
3541 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
3542 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
3543 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
3545 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
3546 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
3548 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3550 * bootstrap: Adjust to today's change to gnulib-tool by invoking
3551 it with --assume-autoconf='latest-stable'.
3553 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
3555 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
3556 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
3558 * src/muscle_tab.h (muscle_grow): Replace the header comments with
3559 those from muscle_tab.c since the old ones are misleading.
3561 2006-07-13 Akim Demaille <akim@epita.fr>
3563 Support %define "KEY" {VALUE}.
3564 * src/scan-code.h, src/scan-code.l (translate_action)
3565 (translate_rule_action, translate_symbol_action, translate_code):
3566 Return char *, not const char *.
3567 * src/parse-gram.y (declaration): Rename as...
3568 (prologue_declaration): this.
3569 (string_content): Remove this nonterminal, use STRING.
3570 (braceless, content, content.opt): New nonterminal.
3572 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
3574 * src/scan-gram.l (getargs.h): Don't include it.
3576 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
3578 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
3579 rather than a for-loop that declares a local bool variable. This
3580 should work around a compatibility problem with a Cray x1e C++
3581 compiler reported by Hung Nguyen in
3582 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
3583 The for-loop was introduced in the 2004-11-17 change but I don't
3584 know why it was needed.
3586 2006-07-12 Akim Demaille <akim@epita.fr>
3588 * data/c.m4: Comment changes.
3590 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
3592 * src/complain.c (error_message, ERROR_MESSAGE): New.
3594 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
3595 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
3597 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
3599 * NEWS: Instead of %union, you can define and use your own union type
3600 YYSTYPE if your grammar contains at least one <type> tag.
3601 Your YYSTYPE need not be a macro; it can be a typedef.
3602 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
3603 (Union Decl, Decl Summary): Document this.
3604 * data/glr.c (YYSTYPE): Implement this.
3605 * data/glr.cc (YYSTYPE): Likewise.
3606 * data/lalr1.cc (YYSTYPE): Likewise.
3607 * data/yacc.c (YYSTYPE): Likewise.
3608 * src/output.c (prepare): Output tag_seen_flag.
3609 * src/parse-gram.y (declaration, grammar_declaration):
3610 Use 'union_seen' rather than 'typed' to determine whether
3611 %union has been seen, since grammars can now be typed without
3613 (symbol_declaration, type.opt, symbol_def):
3614 Keep track of whether a tag has been seen.
3615 * src/reader.c (union_seen, tag_seen): New vars.
3617 * src/reader.h (union_seen, tag_seen, typed): Likewise.
3618 * src/scan-code.l (untyped_var_seen): New variable.
3619 (handle_action_dollar): Adjust to above changes.
3620 (handle_action_dollar, handle_action_at):
3621 Improve overflow checking for outlandish numbers.
3622 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
3623 avoid new diagnostics generated by above changes.
3624 * tests/regression.at (YYSTYPE typedef): Add test to check
3625 for type tags without %union.
3627 * src/symlist.c (symbol_list_length): Return int, not unsigned
3628 int, since callers expect int. This may need to get revisited
3629 once we have proper integer overflow checking.
3631 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
3632 object is now static.
3634 * src/getargs.c (flags_argmatch): Return void, not int,
3635 to pacify ./configure --enable-gcc-warnings.
3637 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
3638 since last_string is already defined to FLEX_PREFIX (last_string).
3640 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
3642 Implement --warnings/-W.
3643 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
3645 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
3647 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
3648 (warnings_args, warnings_types): New.
3649 (getargs, short_options, long_options): Accept -W/--warnings.
3650 Sort the options by alphabetical order, upper case letter right
3651 before its lower case.
3653 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3655 Change %merge result type clash warnings to errors. Discussed at
3656 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
3657 * src/reader.c (record_merge_function_type): Use complain_at.
3658 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3659 declared later): Update test case results.
3661 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
3663 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
3664 to be in alphabetical order.
3665 (trace_args): Spelling fixes.
3667 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
3669 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
3670 so they don't collide with user-defined macros.
3671 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
3672 this was never guaranteed, and now that we're using gnulib stdint,
3673 which defines int_fast16_t to long int, the problem is exposed.
3675 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
3677 * data/c.m4 (b4_basename): Simplify a bit, since we don't
3678 need the full POSIX semantics (and weren't implementing them
3681 Adjust to Autoconf 2.60 and today's gnulib.
3682 * bootstrap (gnulib_modules): Add stdint.
3683 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
3684 no longer copies it.
3685 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
3686 since stdint needs the former and wcwidth (which is now required
3687 by mbswidth) needs the latter.
3688 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
3689 work around a compatibility glitch between gettext 0.14.6 and
3691 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
3692 Do not check for uintptr_t, since new stdint module does the right
3694 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
3695 Add stdint.h, stdint_.h, wcwidth.h.
3696 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
3697 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
3698 stdint.m4, wchar_t.m4, wcwidth.m4.
3699 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
3700 usual order for ../lib/*.h files.
3701 (file_name_split): Use last_component, not base_name, to adjust
3703 * src/parse-gram.h: Include <strverscmp.h> in the usual order
3704 for ../lib/*.h files.
3705 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
3706 Define unconditionally, since we now assume the stdint module.
3707 * src/scan-skel.l: Include <dirname.h>.
3708 (BASE_QPUTS): Use last_component, not base_name.
3709 * src/system.h: Include <unlocked-io.h> in the usual order
3710 for ../lib/*.h files. Include <stdint.h> unconditionally,
3711 since we now use the stdint module.
3712 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
3713 HAVE_UINTPTR_T, since we now use the stdint module.
3714 (base_name): Remove decl, since files now include <dirname.h>
3717 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
3719 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
3721 * data/yacc.c, data/glr.c, data/location.cc: Use them.
3722 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
3724 * tests/calc.at: Adjust.
3726 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
3728 * data/c.m4 (b4_basename): New.
3729 (b4_syncline): Also output the location of its invocation (from
3731 (b4_user_action, b4_define_user_action, b4_user_actions)
3732 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
3733 (b4_user_stype): New.
3734 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
3736 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
3738 In the grammar file, the first column is 1 not 0 on the first line as
3739 on every other line.
3740 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
3741 * tests/input.at (Torturing the Scanner): Update output.
3743 * src/scan-gram.l (scanner_cursor): Declare it static.
3745 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
3747 In warnings, say "previous declaration" rather than "first
3749 * src/symtab.c (redeclaration): Do that here.
3750 * src/reader.c (record_merge_function_type): In the case of a result
3751 type clash, report the previous declaration rather than the very first
3752 one in the grammar file.
3753 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3754 declared later): Add a third declaration to check this behavior.
3755 * tests/input.at (Incompatible Aliases): Update output.
3757 2006-06-27 Akim Demaille <akim@epita.fr>
3759 * doc/Doxyfile.in: New.
3760 * doc/Makefile.am: Use it.
3761 * src/lalr.h, src/symtab.h: Initial doxygenation.
3763 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3765 Don't miss %merge result type warnings just because the LHS types are
3766 declared after the %merge. This continues the effort of the previous
3768 * src/reader.c (get_merge_function): Don't set the merger type yet.
3769 (record_merge_function_type): New function for setting the merger type
3770 and checking for clashes.
3771 (grammar_current_rule_merge_set): Set the location of the %merge for
3773 (packgram): Invoke record_merge_function_type for each rule now that
3774 all symbol type declarations have been parsed.
3775 * src/reader.h (merger_list.type_declaration_location): New member
3776 storing the location of the first %merge from which the type for this
3777 merging function was derived.
3778 * src/symlist.h (symbol_list.merger_declaration_location): New member
3779 storing the location of a rule's %merge, if any.
3780 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
3781 declared later): New test to catch the error fixed by the above patch.
3783 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3785 Get action warnings (grammar_rule_check) right even when symbol
3786 declarations appear after the rules. Discussed at
3787 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
3789 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
3790 Don't mistake the type of $$ in a midrule to be that of its parent
3792 * src/reader.c (grammar_current_rule_end): Don't invoke
3793 grammar_rule_check yet since not all symbol declarations may have been
3795 (grammar_midrule_action): Likewise.
3796 Don't record whether the midrule's $$ has been used yet since actions
3797 haven't been translated yet.
3798 Record the midrule's parent rule and its RHS index within the parent
3800 (grammar_current_rule_action_append): Don't translate the action yet
3801 since not all symbol declarations may have been parsed yet and, thus,
3802 warnings about types for $$, $n, @$, and @n can't be reported yet.
3803 (packgram): Translate the action and invoke grammar_rule_check now that
3804 all symbol declarations have been parsed.
3805 * src/scan-code.l (handle_action_dollar): Now that this is invoked
3806 after parsing the entire grammar file, the symbol list here in the case
3807 of a midrule is actually the midrule's empty RHS, so reference its
3808 parent rule's RHS where necessary.
3809 On the other hand, now that you can already know it's a midrule, you
3810 aren't forced to think $$ has the same type as its parent rule's $$.
3811 (handle_action_at): In the case of a midrule, reference the parent rule
3813 * src/symlist.c (symbol_list_new): Initialize new midrule-related
3815 (symbol_list_length): Now that this is invoked after all rules have
3816 been parsed, a NULL symbol (rather than a NULL symbol list node)
3817 terminates a rule. symbol_list_print already does this correctly.
3818 * src/symlist.h (symbol_list.midrule_parent_rule,
3819 symbol_list.midrule_parent_rhs_index): New members so that midrules can
3820 remember their relationships with their parents.
3821 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
3822 fixed by the above patch.
3823 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
3825 (Unused values): ... this old test case and...
3826 (Unused values before symbol declarations): ... this new test case.
3827 This one is the same as `Unused values' except that all symbol
3828 declarations appear after the rules in order to catch the rest of the
3829 errors fixed by the above patch.
3831 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
3834 * src/reader.c (current_rule): Declare it static since it's no longer
3835 used outside this file.
3836 (grammar_current_rule_action_append): Remove redundant arguments from
3837 translate_rule_action invocation.
3838 * src/reader.h (current_rule): Remove this unused extern.
3839 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
3840 * src/scan-code.l (translate_rule_action): Likewise.
3842 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
3844 Clean up yesterday's patch.
3845 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
3847 * src/reader.c (grammar_current_rule_action_append): ... here for
3848 consistency with grammar_current_rule_symbol_append.
3849 * tests/regression.at (Braced code in declaration in rules section):
3850 Make yyerror and yylex static as usual.
3852 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
3854 Fix bug that mistakes braced code in a declaration in the rules section
3855 to be a rule action. Mentioned at
3856 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
3857 * src/scan-gram.l: Move midrule action detection from the start of the
3858 scanning of any braced code to...
3859 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
3860 action. For readability, use $2 and @2 rather than the equivalent
3862 * tests/regression.at (Braced code in declaration in rules section):
3863 New test to catch the error fixed by the above patch.
3865 Work on code readability some.
3866 * src/scan-code.l (current_rule): Get rid of this misleading and
3867 redundant declaration: it's actually extern'ed in reader.h.
3868 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
3869 translate_action): Add a rule argument and use it instead of the global
3871 (translate_rule_action): This already receives current_rule through an
3872 argument, so pass it on to translate_action instead of assigning
3873 current_rule to current_rule.
3874 (translate_symbol_action, translate_code): Pass rule = NULL to
3877 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
3879 Rename %before-definitions to %start-header and %after-definitions to
3880 %end-header. Don't use these declarations to separate pre-prologue
3881 blocks from post-prologue blocks. Add new order-independent
3882 declarations %before-header and %after-header as alternatives to the
3883 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
3884 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
3885 * NEWS (2.3+): Update for these changes.
3886 * data/glr.c (b4_before_definitions): Update to...
3887 (b4_start_header): ... this.
3888 (b4_after_definitions): Update to...
3889 (b4_end_header): ... this.
3890 * data/glr.cc: Likewise.
3891 * data/lalr1.cc: Likewise.
3892 * data/yacc.c: Likewise.
3893 * doc/bison.texinfo (The prologue): Update names, and replace remaining
3894 prologue blocks with %*-header declarations.
3895 (Calc++ Parser): Likewise.
3896 (Decl Summary): Update names.
3897 (Table of Symbols): Update description.
3898 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
3899 (PERCENT_END_HEADER): ... this.
3900 (PERCENT_BEFORE_DEFINITIONS): Update to...
3901 (PERCENT_START_HEADER): ... this.
3902 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
3903 (declaration): Update token names and m4 macro names.
3904 When parsing %end-header and %start-header, invoke translate_code
3905 before muscle_code_grow, and no longer set global booleans to remember
3906 whether these declarations have been seen.
3907 Parse new %after-header and %before-header.
3908 * src/reader.c (before_definitions, after_definitions): Remove.
3909 (prologue_augment): Accept a new bool argument to specify whether to
3910 augment the pre-prologue or post-prologue.
3911 * src/reader.h (before_definitions, after_definitions): Remove these
3913 (prologue_augment): Add new bool argument.
3914 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
3915 (PERCENT_END_HEADER): ... this.
3916 (PERCENT_BEFORE_DEFINITIONS): Update to...
3917 (PERCENT_START_HEADER): ... this.
3918 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
3919 * tests/actions.at (Printers and Destructors): Update names.
3921 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
3923 Add comparison operators for C++ location classes. Discussed at
3924 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
3925 * data/c++.m4 (b4_define_location_comparison): New boolean %define
3926 declaration indicating whether filename_type has an operator==. If
3927 filename_type is `std::string', it defaults to `1', `0' otherwise.
3928 * data/location.cc: Iff b4_define_location_comparison is `1', add
3929 operator== and operator!= for class position and for class location.
3932 * src/scan-action.l: Remove unused file.
3933 * src/symtab.c (symbol_printer_set): Use printer_location not
3934 destructor_location.
3935 * src/symtab.h (struct symbol): Replace incorrect source comment for
3937 * tests/input.at (Incompatible Aliases): Update output with correct
3940 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
3942 Don't put the pre-prologue in the header file. For the yacc.c code
3943 file and the glr.c header and code files, move the pre-prologue before
3944 the token definitions. Add new %before-definitions and
3945 %after-definitions to declare code that will go in both the header file
3946 and code file. Discussed at
3947 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
3948 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
3950 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
3951 * NEWS (2.3+): Describe these changes.
3952 * data/glr.c (b4_pre_prologue): Move from within to before...
3953 (b4_shared_declarations): ... this.
3954 Add new b4_before_definitions before b4_token_enums.
3955 Add new b4_after_definitions at the end.
3956 * data/glr.cc (b4_pre_prologue): Replace with...
3957 (b4_before_definitions): ... this in the header file.
3958 (b4_after_definitions): New near the end of the header file.
3959 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
3960 code file right before including the header file.
3961 (b4_before_definitions): New in the previous position of
3962 b4_pre_prologue in the header file.
3963 (b4_after_definitions): New near the end of the header file.
3964 * data/yacc.c: Clean up some m4 quoting especially in the header file.
3965 (b4_token_enums_defines): In the code file, move to right before
3966 YYSTYPE for consistency with the header file.
3967 (b4_before_definitions): New right before b4_token_enums_defines in
3968 both the header and code file.
3969 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
3970 header and code file.
3971 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
3972 of prologues for %union dependencies.
3973 (Decl Summary): In %defines description, mention the effect of
3974 %before-definitions and %after-definitions on the header file.
3975 (Calc++ Parser): Forward declare driver in a %before-definitions rather
3976 than in the pre-prologue so that make check succeeds.
3977 (Table of Symbols): Add entries for %before-definitions and
3979 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
3980 %before-definitions.
3981 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
3982 (declaration): Parse those declarations and append to
3983 b4_before_definitions and b4_after_definitions, respectively.
3984 * src/reader.c (before_definitions, after_definitions): New bools to
3985 track whether those declarations have been seen.
3986 (prologue_augment): Add to the post-prologue if %union,
3987 %before-definitions, or %after-definitions has been seen.
3988 * src/reader.h (before_definitions, after_definitions): New extern's.
3989 * src/scan-gram.l: Scan the new declarations.
3990 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
3991 prologue block in a %before-definitions or a %after-definitions based
3992 on whether the %union is declared.
3993 * tests/regression.at (Early token definitions with --yacc, Early token
3994 definitions without --yacc): Move tests for token definitions into the
3995 post-prologue since token names are no longer defined in the
3998 2006-06-20 Akim Demaille <akim@epita.fr>
4000 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
4001 (symbol_get): Use it.
4002 * src/parse-gram.y: Use it.
4004 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
4006 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
4007 build succeeds when configured with --enable-gcc-warnings.
4009 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4011 * src/parse-gram.y (char_name): New function.
4012 (CHAR, STRING, string_content): For %printer, properly escape.
4013 (ID): Prefer fputs to fprintf.
4014 (id): Reindent to be consistent with other rules.
4015 Properly quote char.
4017 The Translation Project changed its way of publishing translations
4018 to maintainers. I haven't received any responses to my request
4019 for supporting the old way, or for documenting the new way. I
4020 have modified 'bootstrap' to use screen scraping
4021 (in this case, HTML scraping). This is unreliable and inelegant,
4022 but I don't see any better way. Yuck.
4023 * bootstrap (TP_URL, WGET_COMMAND): New vars.
4024 (get_translations): New function, which uses HTML scraping to
4025 deduce locations of latest translations.
4026 Use this function to grab both bison and bison-runtime .po files.
4027 Don't bother priming the pump for the runtime-po domain any more,
4028 as it's now translated better than bison is.
4030 2006-06-19 Akim Demaille <akim@epita.fr>
4032 * src/scan-gram.l: No longer "parse" things after `%union' until
4033 `{'. Rather, return a single "%union" token.
4034 No longer make symbols: return strings, and leave the conversion
4035 to symbols to the parser.
4036 (SC_PRE_CODE, token_type): Remove.
4037 * src/parse-gram.y (%union): New field `character'.
4040 (ID, ID_COLON): Now that the scanner no longer makes them
4041 identifiers, adjust all uses to invoke symbol_get.
4042 (id_colon): New, wraps the conversion from string to symbol.
4043 (%union): Accept a possible union_name.
4044 (symbol): Now can be a char.
4045 * data/c.m4 (b4_union_name): Leave a default value.
4046 * data/glr.c, data/yacc.c: Use it.
4048 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
4050 For associating token numbers with token names for "yacc.c", don't use
4051 #define statements unless `--yacc' is specified; always use enum
4052 yytokentype. Most important discussions start at:
4053 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,

4056 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
4057 * NEWS (2.3+): Mention.
4058 * data/c.m4 (b4_yacc_if): New.
4059 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
4061 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
4062 on token name definitions.
4063 * src/getargs.c (usage): Capitalize `Yacc' in English.
4064 * src/output.c (prepare): Define b4_yacc_flag.
4065 * tests/regression.at (Early token definitions): Test that tokens names
4066 are defined before the pre-prologue not just before the post-prologue.
4067 Remove this test case and copy to...
4068 (Early token definitions with --yacc): ... this to test #define's.
4069 (Early token definitions without --yacc): ... and this to test enums.

4073 * NEWS: Reword the post-2.3 change to not be so optimistic about
4074 removing the old "look-ahead" spelling.
4075 Update previous look-ahead/lookahead change reports.
4076 * REFERENCES: look-ahead -> lookahead (since that's
4077 what he actually wrote).

4079 look-ahead -> lookahead
4081 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
4083 For consistency, use `lookahead' instead of `look-ahead' or

4160 * TODO: Add request from Nelson H. F. Beebe to be able to install
4161 Bison without installing the yacc script.
4163 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
4165 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
4166 and yytext if they're already #define'd.
4167 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
4168 * src/scan-code-c.c: ... here.
4169 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include

4174 Get Bison to build again when configured with --enable-gcc-warnings.
4175 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
4177 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
4178 loc argument as it shadows a global.
4179 * src/scan-gram.l: Remove stray comma that prevents boundary_set
4182 * src/.cvsignore: Add scan-code.c.
4184 2006-06-07 Akim Demaille <akim@epita.fr>
4186 * src/scan-gram.l: Move the "add a trailing ; to actions" code
4188 * src/scan-code.l: here.

4192 2006-06-07 Akim Demaille <akim@epita.fr>
4194 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
4196 2006-06-06 Akim Demaille <akim@epita.fr>
4198 Extract the parsing of user actions from the grammar scanner.
4199 As a consequence, the relation between the grammar scanner and
4200 parser is much simpler. We can also split "composite tokens" back
4202 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
4203 * src/scan-gram.l (add_column_width, adjust_location): Move to and
4205 * src/location.h, src/location.c (add_column_width)
4206 (location_compute): these.
4207 Fix the column count: the initial column is 0.
4208 (location_print): Be robust to ending column being 0.
4209 * src/location.h (boundary_set): New.
4210 * src/main.c: Adjust to scanner_free being renamed as
4212 * src/output.c: Include scan-code.h.
4213 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
4215 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
4216 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
4217 which is now, again, a separate token.
4218 Adjust all dependencies.
4219 Whereever actions with $ and @ are used, use translate_code.
4220 (action): Remove this nonterminal which is now useless.
4221 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
4222 (grammar_current_rule_action_append): Use translate_code.

4229 (YY_DECL): Rename as...
4231 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
4232 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
4233 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
4234 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

4240 (increment_rule_length): Remove.
4241 (last_braced_code_loc): Rename as...
4242 (gram_last_braced_code_loc): this.
4243 Adjust to the changes of the parser.
4244 Move all the handling of $ and @ into...
4245 * src/scan-code.l: here.
4246 * src/scan-gram.l (handle_dollar, handle_at): Remove.

4259 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4261 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4262 Use Akim's wording from
4263 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
4265 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4267 Between Bison releases, manually append `+' to the previous Bison
4268 release number, and use that as a signal to automatically print the
4269 ChangeLog's CVS Id keyword from --version. Discussed starting at
4270 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
4271 * ChangeLog: Add Id header.
4272 * configure.ac (AC_INIT): Append `+' to `2.3'.
4273 * src/.cvsignore: Add revision.c.
4274 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
4275 (BUILT_SOURCES): Add revision.c.
4276 (revision.c): New target rule. This file defines a new global variable
4277 named revision. It initializes it with either the Id from ChangeLog
4278 or, if VERSION doesn't contain `+', with the empty string.
4279 * src/getargs.c (version): Print the value of revision.
4280 * src/revision.h: Extern revision.
4282 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4284 * NEWS: Version 2.3.
4285 * configure.ac (AC_INIT): Likewise.
4287 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4289 * data/glr.c (YYRECOVERING): Define to be a function-like macro
4290 with no arguments, not as an object-like macro. This is for
4291 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
4292 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
4293 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
4296 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
4298 * src/getargs.c (usage): Back out yesterday's modification of the
4299 --help output so that we don't have to wait for translation before
4302 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4304 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
4305 Problem reported by Akim Demaille.
4307 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4309 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4311 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4313 * data/yacc.c (yy_reduce_print): Omit trailing white space in
4314 generated source code. Problem reported by Frans Englich in
4315 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
4317 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
4319 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
4320 shell, not within 'make', so that 'make' by an ordinary builder
4321 (using GNU make) does not worry about configuring gzip. This also
4322 works around a bug reported independently by Keith Thompson and by
4323 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
4324 stderr rather than stdout, messing up the build logs.
4326 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4328 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
4329 to make sure that YYID will never be unused. This fixes a 'make
4330 maintainer-check' failure caused by the recent changes to the 'Trivial
4331 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
4333 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
4335 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4337 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
4338 state before an empty RHS is always resolved here. Only the location
4339 of that state is guaranteed to be resolved, and that's enough. This
4340 fixes the remaining bug reported by Derek M. Jones in
4341 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4342 * tests/glr-regression.at (Uninitialized location when reporting
4343 ambiguity): Test the above case.
4344 Also, the embedded comments in this test case claim it checks the case
4345 of an empty RHS that has inherited the initial location. However, the
4346 corresponding LHS was already resolved, so yyresolveLocations didn't
4347 actually have reason to modify it. Fix this by forcing
4348 nondeterministic operation at the beginning of the parse.
4350 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4352 * data/c.m4 (b4_yy_symbol_print_generate):
4353 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
4354 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
4355 of the bugs reported today by Derek M Jones in
4356 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4357 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
4358 defined to be a type name without parens or brackets.
4359 (Location Type): Similarly for YYLTYPE.
4360 * tests/regression.at (Trivial grammars): Put in a test for this
4361 bug that will be caught by 'make maintainer-check' (though not,
4362 alas, by 'make check' unless your compiler is picky).
4364 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4366 * NEWS: Version 2.2.
4367 * configure.ac (AC_INIT): Likewise.
4369 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
4371 * data/glr.c (yyreportTree): Make room in yystates for the state
4372 preceding the RHS. This fixes the segmentation fault reported by Derek
4374 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
4375 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
4376 to the user. Reported for yyreportTree by Derek M. Jones later in the
4378 * THANKS: Add Derek M. Jones.
4379 Update my email address.
4380 Fix typo in Steve Murphy's name.
4382 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4384 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
4385 checking against YYLAST that caused the parser to miss a potential
4386 alternative in its diagnostic.
4387 Problem reported by Maria Jose Moron Fernandez in
4388 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
4389 * data/lalr1.cc (yysyntax_error_): Likewise.
4390 * data/yacc.c (yysyntax_error): Likewise.
4391 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
4392 tokens, in case we run into an older C compiler.
4393 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
4394 Use them to check for the off-by-one error fixed above.
4396 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
4397 YYSIZE_T, not size_t.
4398 * tests/regression.at (Trivial grammars): New test, to catch
4399 the error fixed by the above patch.
4401 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4403 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
4405 Reported by Steve Murphy.
4407 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4409 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
4410 * data/glr.cc: b4_location_flag is now b4_locations_flag.
4412 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4414 Implement --trace=m4.
4415 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
4416 * src/output.c (output_skeleton): When set, pass -dV to m4.
4418 Factor the handling of flags in m4.
4419 * src/output.c (prepare): Rename the muscle names debug, defines,
4420 error_verbose to debug_flag, defines_flag, error_verbose_flag.
4421 * data/c.m4: Adjust.
4422 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
4423 Use b4_define_flag_if to define other b4_FLAG_if macros.
4424 (b4_location_if): As a consequence, rename as...
4425 (b4_locations_if): this, for consistency.
4426 Adjust all the skeletons.
4428 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4430 * etc/bench.pm: Shorten bench names.
4432 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4434 * src/output.h, src/output.c (error_verbose): Move to...
4435 * src/getargs.h, src/getargs.c: here.
4437 Adjust dependencies.
4439 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4441 * data/c.m4 (b4_copyright): Put the special exception for Bison
4442 skeletons here, so we don't have to put it in each skeleton. All
4443 uses changed. Suggested by Akim Demaille. Also, wrap the
4444 copyright notice, in case it is longer than 80 columns. Replace
4445 comma by newline after title.
4447 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4449 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
4450 incompatibility, not a bug. Mention that it wasn't fixed as of
4453 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4455 * examples/extexi: Enforce the precedence of concatenation over
4457 Reported by Tommy Nordgren.
4459 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4461 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
4462 with the member "token".
4463 Reported by Martin Nylin.
4465 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
4467 * data/glr.c: Switch to Bison 2.2 special-exception language in
4468 the copyright notice. Use more-regular format for titles and
4470 * data/glr.cc: Likewise.
4471 * data/location.cc: Likewise.
4472 * data/yacc.cc: Likewise.
4473 * doc/bison.texinfo (Conditions): Document this.
4474 * NEWS: likewise. Upgrade version to 2.2.
4476 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
4478 * data/glr.cc: Remove dead code.
4480 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4482 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
4483 that variable and the line breaks the bootstrap. Problem reported
4484 by Juan M. Guerrero.
4486 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
4488 * doc/bison.texinfo (Multiple start-symbols): New.
4490 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
4492 * etc/README, etc/bench.pl: New.
4494 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
4496 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
4498 Reported by Mickael Labau.
4499 * tests/input.at (Torturing the Scanner): Test it.
4501 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
4503 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
4504 Problem reported by Bob Rossi.
4506 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
4508 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
4509 and didn't really work.
4510 For the index, use @ifnotinfo, not @iftex.
4511 Minor cleanups of spacing and terminology.
4513 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4515 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
4516 of AT_NAME_PREFIX when %name-prefix is not used.
4518 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4520 Apply --prefix to C++ skeletons too: they change the namespace.
4521 The test suite already exercize these cases.
4522 * data/c++.m4 (b4_namespace): New.
4523 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
4524 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
4525 * data/yacc.c, data/glr.c: Remove a useless `[]'.
4526 * doc/bison.texinfo: Document it.
4527 (Option Cross Key): Use @multitable in all formats. It looks
4528 nicer, even in TeX outputs.
4529 (Rules): Use the same code whatever the output type is.
4530 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
4531 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
4532 * tests/calc.at: Use it, instead of hard coding `yy'.
4534 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
4536 * TODO: Remove dead items.
4538 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
4540 * doc/FAQ: Remove, merged into...
4541 * doc/bison.texinfo (FAQ): this.
4542 * doc/Makefile.am (EXTRA_DIST): Adjust.
4544 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
4546 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
4548 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
4549 * doc/bison.texinfo (Calc++ Scanner): Use it.
4551 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
4553 Fix two nits reported by twlevo, plus one more that I discovered.
4555 * src/assoc.h (assoc_to_string): Give a name to the arg, as
4556 this is the usual Bison style.
4557 * src/location.h (location_print): Likewise.
4559 * src/reader.h (token_name): Likewise.
4561 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
4563 Fix some nits reported by twlevo.
4564 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
4565 and "POSIX". Use more-modern syntax for URLs. Mention C++
4566 and ask for Java. Don't hardwire OS version numbers. Add
4568 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
4569 * src/conflicts.c (solved_conflicts_obstack): Now static.
4571 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
4573 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
4574 page. Say "you can use it" not "you may use it" as on the web page;
4575 we're describing capabilities not granting permission.
4577 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
4579 * data/glr.c (yyresolveLocations): Rename local variables to avoid
4580 shadowing warnings. Use usual patter for iterating through RHS.
4581 * tests/glr-regression.at
4582 (Uninitialized location when reporting ambiguity):
4583 Modify yylex so that it uses its argument, rather than trying
4584 to rely on ARGSUSED (which doesn't work for gcc with warnings).
4585 const char -> char const.
4587 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
4588 Don't use tabs inside commands; it messes up 'ps'.
4589 Problem reported by twlevo.
4591 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
4593 * tests/glr-regression.at (Uninitialized location when reporting
4594 ambiguity): New test case.
4595 * data/glr.c (yyresolveLocations): New function, which uses
4597 (yyresolveValue): Invoke yyresolveLocations before reporting an
4599 * doc/bison.texinfo (Default Action for Locations): Note
4600 YYLLOC_DEFAULT's usage for ambiguity locations.
4601 (GLR Semantic Actions): Cross-reference those notes.
4603 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
4605 * tests/glr-regression.at (Leaked semantic values when reporting
4606 ambiguity): Remove unnecessary union and type declarations.
4607 (Leaked lookahead after nondeterministic parse syntax error): New test
4609 * data/glr.c (yyparse): Check for zero stacks remaining before
4610 attempting to shift the lookahead so that you don't lose it.
4612 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
4614 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
4615 * tests/glr-regression.at (Leaked semantic values when reporting
4616 ambiguity): New test case.
4617 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
4618 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
4619 now unnecessary yystackp parameter.
4620 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
4621 destructors can be called.
4623 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
4624 in existing testcases.
4626 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
4628 Don't leak semantic values for parent RHS when a user action cuts the
4629 parser, and clean up related code a bit.
4630 * tests/glr-regression.at (Leaked merged semantic value if user action
4631 cuts parse): Rename to...
4632 (Leaked semantic values if user action cuts parse): ... this. Add check
4633 for leaked parent RHS values.
4634 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
4635 between an unresolved state (non-empty chain of semantic options) and
4636 an incomplete one (signaled by an empty chain).
4637 (yyresolveStates): Document the interface. Move all manipulation of a
4638 successfully or unsuccessfully resolved yyGLRState to...
4639 (yyresolveValue): ... here so that yyresolveValue always leaves a
4640 yyGLRState with consistent data and thus is easier to understand.
4641 Remove the yyvalp and yylocp parameters since they are always just
4642 taken from the yys parameter. When reporting a discarded merged value
4643 in debugging output, note that it is incompletely merged. Document the
4645 (yyresolveAction): If resolving any of the RHS states fails, destroy
4646 them all rather than leaking them. Thus, as long as user actions are
4647 written to clean up the RHS correctly, yyresolveAction always cleans up
4648 the RHS of a semantic option. Document the interface.
4650 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
4652 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
4653 led to a segmentation fault in GNU Pascal. Problem reported
4656 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
4658 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
4659 mid-rule action inside a nonterminal symbol in order to declare a
4660 destructor for its semantic value.
4662 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
4664 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
4665 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
4666 __cplusplus && ! defined _STDLIB_H && !
4667 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
4668 defined free))]: Include <stdlib.h> rather than rolling our own
4669 declarations of malloc and free, to avoid problems with
4670 incompatible declarations (using 'throw') C++'s stdlib.h. This
4671 should fix Debian bug 340012

4683 * NEWS: Version 2.1a.
4684 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
4685 since C99 requires this.
4687 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
4689 * m4/c-working.m4: New file.
4690 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
4692 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
4694 * Makefile.maint: Merge from coreutils.
4696 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
4698 More portability fixes for problems summarized by Nelson H. F. Beebe.
4700 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
4701 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
4702 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
4703 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

4709 More portability fixes for problems summarized by Nelson H. F. Beebe.
4711 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
4712 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
4714 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
4715 nodist_PROGRAMS, since we don't need to actually compile the
4716 example if we're just doing a plain 'make'. This avoids bothering
4717 the installer unnecessarily about problems due to weird C++

4722 More portability fixes for problems summarized by Nelson H. F. Beebe.
4724 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
4725 than #include "...", and compile with -I'.'. The old method was
4726 not portable, according to Posix and the C standard, and it does
4727 not work with Sun C 5.7, where previous #line directives affect
4728 the working directory used in later #include "..." directives.

4739 '#include <map>' works and that you can apply ++ to iterators.
4741 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
4743 Work around portability problems summarized by Nelson H. F. Beebe in

4747 that '#include <string>' works.
4749 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
4750 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
4751 "warning: sorry: semantics of inline function static data `const
4752 unsigned char translate_table[262]' are wrong (you'll wind up with
4755 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
4756 or, xor to not_, and_, or_, and xor_, respectively. This works
4757 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
4758 random system header somewhere that includes the equivalent of
4761 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
4762 -E" works; it apparently doesn't work with PathScale EKO Compiler
4765 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
4767 During deterministic GLR operation, user actions should be able to
4768 influence the parse by changing yychar. To make this easier to fix and
4769 to make glr.c easier to evolve in general, don't maintain yytoken in
4770 parallel with yychar; just compute yytoken when needed.
4771 * tests/glr-regression.at (Incorrect lookahead during deterministic
4772 GLR): Check that setting yychar in a user action has the intended
4774 * data/glr.c (yyGLRStack): Remove yytokenp member.
4775 (yyclearin): Don't set *yytokenp.
4776 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
4777 yychar rather than *yytokenp to determine the current lookahead.
4778 Compute yytoken locally when needed.
4779 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
4782 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
4783 after `--report' documentation.

4794 all the test at once. This makes the output easier to read in the
4797 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
4798 got from <http://bro-ids.org/download.html>. The bug is that
4799 when two actions appeared in succession, the second one was
4800 scanned before the first one was added to the grammar rule
4801 as a midrule action. Bison then output the incorrect warning
4802 "parse.y:905.17-906.36: warning: unused value: $3".
4803 * src/parse-gram.y (BRACED_CODE, action): These are no longer
4804 associated with a value.
4805 (rhs): Don't invoke grammar_current_rule_action_append.
4806 (action): Invoke it here instead.
4807 * src/reader.c (grammar_midrule_action): Now extern.
4808 (grammar_current_rule_action_append): Don't invoke
4809 grammar_midrule_action; that is now the scanner's job.
4810 * src/reader.h (last_string, last_braced_code_loc):
4811 (grammar_midrule_action): New decls.
4812 * src/scan-gram.l (last_string): Now extern, sigh.
4813 (last_braced_code_loc): New extern variable.
4814 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
4815 rule already has an action.
4816 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
4817 * tests/input.at (AT_CHECK_UNUSED_VALUES):
4818 Add some tests to check that the above changes fixed the bug.
4820 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
4822 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
4823 All used changed. Check whether the symbol has a destructor,
4824 not whether it is typed.
4825 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
4826 that the values are still reported as unused. All line numbers

4843 user can override the types.
4844 (short): #undef, to work around a bug in Pike 7.0.
4845 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
4846 (union yyalloc.yyss): Use yytype_int16 rather than short.
4848 (yysigned_char): Remove.
4849 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
4850 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.

4873 since we don't want to insist on a version number at the start
4874 of the changelog every time.
4875 * Makefile.maint: Sync from coreutils a bit better.
4876 (sc_trailing_blank): Renamed from sc_trailing_space.
4878 (sc_no_if_have_config_h, sc_require_config_h):
4879 (sc_prohibit_assert_without_use): New rules.

5064 in the yychar entry.
5065 In the yychar entry, remove mention of the local yychar case (pure
5066 parser) since this is irrelevant information when writing semantic
5067 actions and since it's already discussed in `Table of Symbols' where
5068 yychar is otherwise described as an external variable.
5069 In the yychar entry, don't call it the `current' look-ahead since it
5070 isn't when semantic actions are deferred.
5071 In the yychar and yyclearin entries, add note about deferred semantic
5073 Add yylloc and yylval entries discussing look-ahead usage.
5074 (Look-Ahead Tokens): When discussing yychar, don't call it the

5099 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
5100 from which the RHS is taken. Set the lookahead members of the new

5103 yyaddDeferredAction.

5114 (Incorrect lookahead during deterministic GLR): New test case.
5115 (Incorrect lookahead during nondeterministic GLR): New test case.
5117 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

5129 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5131 * data/glr.c (yyresolveValue): When merging semantic options, if at
5132 least one user action succeeds but a later one cuts the parse, then
5133 destroy the semantic value before returning rather than leaking it.
5134 (yyresolveStates): If a user action cuts the parse and thus
5135 yyresolveValue fails, ignore the (unset) semantic value rather than
5136 corrupting the yyGLRState, and empty the semantic options list since
5137 the user actions should have called all necessary destructors.
5138 Simplify code with YYCHK.
5139 * tests/glr-regression.at (Corrupted semantic options if user action
5140 cuts parse): New test case.
5141 (Undesirable destructors if user action cuts parse): New test case.

5388 destroy the RHS symbols of a rule.
5389 * data/yacc.c (yylen): Initialize to 0.
5390 Keep its value to the number of items to possibly shift.
5391 In particular, a regular successful parse that ends on YYFINAL by
5392 a (internal) YYACCEPT must not have yylen != 0.
5393 (yyerrorlab, yyreturn): Pop the RHS.
5394 Reorder a bit to emphasize the `shifting' bits of code.
5395 (YYPOPSTACK): Now accept a number of items to pop.

5405 * djgpp/config.bat: Replace every occurence of the file name
5406 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
5407 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
5408 * djgpp/config.sed: Replace every occurence of the file name
5409 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

5415 using djunpack.bat and fnchange.lst.
5417 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
5419 * bootstrap (build_cvs_prefix): Remove; unused.
5420 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
5421 when getting gnulib.

5439 sed out the final state number.
5441 Work around portability problem on Solaris 10: flex-generated
5442 files include <stdio.h> before <config.h>, which messes up
5443 because the latter defines __EXTENSIONS__. Address the problem
5444 by creating two new little files that include <config.h> first,
5445 then include the flex-generated files. Rewrite everyone else
5446 to include <config.h> first, as well.
5447 * lib/timevar.c: Always include "config.h".
5448 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

5489 definition if 'lint' is defined.
5490 (YYID): New macro (or function, if lint).
5491 All uses of /*CONSTCOND*/0 replaced by YYID(0).
5492 * data/yacc.c: Likewise.
5493 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
5494 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
5495 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
5497 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
5498 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
5499 Use YYID(0) rather than 0, for lint.
5500 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

5521 * NEWS: Document the following change.
5522 * data/yacc.c: Say "parser skeleton" rather than "file", since
5523 it's no longer just a file.
5524 * data/glr.c: Grant a special exception for C GLR parsers, that
5525 reads like the already-existing exception for C LALR(1) parsers.
5526 * data/glr.cc: Likewise.
5527 * data/lalr1.cc: Likewise.
5528 * data/location.cc: Likewise.

5541 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
5542 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
5543 We can revert this once things settle down.
5545 * src/conflicts.c (conflicts_print): Don't print file name twice
5546 when %expect fails because there were no conflicts.
5547 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous

5619 Have glr.c include its header file when created.

5786 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
5788 Undo the parts of the unlocked-I/O change that substituted
5789 putc or puts for printf. This might hurt performance a bit,
5790 but some people prefer the printf style.

5821 Use unlocked I/O for a minor performance improvement on hosts like
5822 GNU/Linux and Solaris that support unlocked I/O. The basic idea
5823 is to use the gnlib unlocked-io module, and to prefer putc and
5824 puts to printf when either will work (since the latter doesn't
5825 come in an unlocked flavor).
5826 * bootstrap (gnulib_modules): Add unlocked-io.

5892 * lib/subpipe.c: New function end_of_output_subpipe() added
5893 to allow support for non-posix systems. This is a no-op function
5896 * lib/subpipe.h: New function end_of_output_subpipe() added
5897 to allow support for non-posix systems. This is a no-op function
5900 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
5901 handle the lack of pipe/fork functionality on non-posix systems.

5969 (yysyntax_error_): Takes the state number as argument.
5970 (yyreduce_print_): Use the argument yyrule, not the former

5985 local variables whose names begin with 'yy'.
5986 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
5987 Trivial changes from Joel E. Denny.
5989 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
5991 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
5992 don't use alloca any more.
5994 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
5995 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
5996 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
5997 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
5998 to match yacc.c, to test more hosts.
6000 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
6002 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
6003 doesn't affect behavior.
6004 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
6006 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
6007 This works a bit better with glibc, if user code has already included
6009 * doc/bison.texinfo (Bison Parser): Document that users can't
6010 arbitrarily use malloc and free for other purposes. Document
6011 that <alloca.h> and <malloc.h> might be included.
6012 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
6013 user must declare alloca.

6022 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
6024 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
6025 (YYSTACK_ALLOC_MAXIMUM): Use it.
6026 (yysyntax_error): New function.
6027 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
6028 multiple syntax errors are reported, and alloca is being used.
6029 Instead, reallocate buffers twice as big each time, so that
6030 we waste at most half the allocated memory. Start with a small
6031 (128-byte) buffer that will suffice in most cases anyway.
6032 Use yysyntax_error to do most of the work.
6034 * doc/bison.texinfo (Error Reporting, Table of Symbols):
6035 yynerrs is the number of errors reported, not the number of
6038 * tests/glr-regression.at (Duplicated user destructor for lookahead):
6039 Mark it as expected to fail.
6040 Cast result of malloc; problem reported by twlevo@xs4all.nl.
6041 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
6042 Don't start user-code symbols with "yy", to avoid name space problems.
6044 2005-09-19 Akim Demaille <akim@epita.fr>
6046 Remove the traits, failed experiment.
6047 It never proved useful, and anyway because of the current
6048 definition, it was not possible to have several specialization of
6049 this traits, making it useless.
6050 * data/lalr1.cc (yy:traits): Remove.
6051 Inline its definitions in the parser class.
6053 2005-09-19 Akim Demaille <akim@epita.fr>

6076 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
6077 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
6078 is not defined. This is an awful hack, but it's enough for now.
6079 All callers changed.
6080 * tests/glr-regression-at (make_value): Args are const pointers now,
6081 to avoid GCC warning.
6082 (Duplicated user destructor for lookahead): New test. Currently
6083 skipped. It fails on my host but I'm not sure it'll always fail.
6085 2005-09-16 Akim Demaille <akim@epita.fr>
6087 * src/symtab.h (struct symbol): Declare the printer and destructor
6088 as const, to avoid accidental calls to free.
6089 (symbol_destructor_set, symbol_printer_set): Adjust.
6090 * src/symtab.c: Adjust.
6092 2005-09-16 Akim Demaille <akim@epita.fr>
6094 * data/c.m4 (b4_token_enums): New.
6095 (b4_token_defines): Rename as...
6096 (b4_token_enums_defines): this.
6097 (b4_token_defines): New, output only the #defines.
6098 * data/yacc.c, data/glr.c: Adjust.
6099 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
6100 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
6103 2005-09-16 Akim Demaille <akim@epita.fr>
6105 * data/lalr1.cc (yylex_): Remove, inline its code.
6106 (yyreport_syntax_error_): Remove, replaced by...
6107 (yysyntax_error_): this which returns a string and leaves to the
6108 caller the call to the users' error function.
6109 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
6110 Move from members of the parser object...
6111 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
6112 to local variables of the parse function.
6114 2005-09-16 Akim Demaille <akim@epita.fr>
6116 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
6117 since it's in Bison's name space.
6119 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
6121 * data/glr.c (yyresolveValue): Add default case to pacify
6122 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
6124 * NEWS: Document when yyparse started to return 2.
6125 * doc/bison.texinfo (Parser Function): Document when yyparse
6128 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
6129 (b4_filename_type): Renamed back from b4_file_name_type. All uses
6131 (class position): file_name -> filename (reverting). All uses changed.
6133 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
6135 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
6136 do anything if $@ exists. This reverts part of the 2005-07-07
6139 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
6141 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
6142 contains obsolete information and isn't worth distributing as a
6143 separate file anyway.
6144 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
6145 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
6146 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
6147 (yyparse): Abort if user code uses longjmp to throw an unexpected
6150 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
6152 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
6153 Suggested by twlevo@xs4all.nl.
6155 * data/glr.c (YYCHK1): Do not assume YYE is in range.
6156 This avoids a diagnostic from gcc -Wswitch-enum.
6157 Problem reported by twlevo@xs4all.nl.
6159 * doc/bison.texinfo: Don't use "filename", as per GNU coding
6160 standards. Use "file name" or "file" or "name", depending on
6162 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
6163 not to hack/foo.tab.c.
6164 (Calc++ Top Level): 2nd arg of main is not const.
6165 * data/glr.c: b4_filename -> b4_file_name.
6166 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
6168 (class position): filename -> file_name. All uses changed.

6177 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
6179 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
6180 to accommodate latest gnulib.
6182 * tests/glr-regression.at (Duplicate representation of merged trees):
6183 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
6185 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
6188 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6190 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
6191 All uses changed. Invoke user destructor after an error during a
6192 split parse (trivial change from Joel E. Denny).
6194 * tests/glr-regression.at
6195 (User destructor after an error during a split parse): New test case.
6196 Problem reported by Joel E. Denny in:
6197 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
6199 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6201 * README-cvs: Give URLs for recommended tools.
6202 Mention Gzip version problem, and bootstrapping issues.
6203 Remove troubleshooting section, as it's somewhat obsolete.
6205 * bootstrap (no_cache): New var, to accommodate different wget
6206 variants. Use it instead of '-C off'. Problem reported by
6209 * data/glr.c (yydestroyStackItem): New function.
6210 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
6211 debugging information. Problem reported by Joel E. Denny.
6213 2005-08-25 Akim Demaille <akim@epita.fr>
6215 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
6217 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

6221 * tests/glr-regression.at
6222 (User destructor for unresolved GLR semantic value): New test case.
6223 Problem reported by Joel E. Denny in:
6224 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
6226 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
6228 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
6230 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
6231 lib-prefix.m4, po.m4.
6233 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
6234 in yydestruct diagnostic, since it might not be an error.
6235 Problem reported by Joel Denny near end of
6236 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6237 * data/lalr1.cc (yyerturn): Likewise.
6238 * data/yacc.c (yyreturn): Likewise.
6239 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
6241 * src/files.c: Remove obsolete FIXME comment.
6243 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
6244 with the other templates, and to fix bogus run-on messages such
6245 as the one reported at the end of
6246 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6247 All callers changed to avoid the newline.
6248 (yyprocessOneStack): Output two lines rather than one, to accommodate
6249 the above change. This changes the debug output format slightly.
6251 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
6252 reported by Joel E. Denny in
6253 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
6255 * tests/glr-regression.at (Duplicate representation of merged trees):
6256 New test, from Joel E. Denny in:
6257 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
6258 * THANKS: Add Joel E. Denny.
6260 * configure.ac (AC_INIT): Bump to 2.0c.
6262 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
6264 * NEWS: Version 2.0b.
6266 * Makefile.am (SUBDIRS): Put examples before tests, so that
6267 "make check" doesn't finish with "All 1 tests passed".
6269 * tests/regression.at (Token definitions): Don't rely on
6270 AT_PARSER_CHECK for data that contains backslashes. It currently
6271 uses 'echo', and 'echo' isn't portable if its argument contains
6272 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
6273 that the byte '\0xff' is not printable in the C locale; it is,
6274 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
6275 not printable, so use '\0x81' to test.
6277 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
6278 version of GCC, since the macro is used with non-GCC compilers.
6280 Fix core dump reported by Pablo De Napoli in
6281 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
6282 * tests/regression.at (Invalid inputs with {}): New test.
6283 * src/parse-gram.y (token_name): Translate type before using
6286 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
6287 the user's name space. All uses changed to __attribute__
6289 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
6290 Add __attribute__ ((__noreturn__)).
6292 * etc/clcommit: Remove. We weren't using it, and it failed
6293 "make maintainer-distcheck".
6294 * Makefile.maint: Merge from coreutils.
6295 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
6296 (syntax-check-rules): Change list of rules as described below.
6297 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
6298 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
6299 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
6300 (sc_trailing_space): New rules.
6301 (sc_xalloc_h_in_src): Remove.
6302 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
6303 (sc_space_tab, sc_error_exit_success, sc_changelog):
6304 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
6305 (makefile-check, po-check, author_mark_check):
6306 (makefile_path_separator_check, copyright-check):
6307 Use grep -n, to make it easier to find violations.
6308 Use CVS_LIST and CVS_LIST_EXCEPT.
6309 (header_regexp, h_re): Remove.
6311 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
6312 (my-distcheck): Use more-modern GCC flags.
6313 (signatures, %.asc): Remove.
6314 (rel-files, announcement): Remove signatures.
6315 Restore old updating code, even though we don't use it, so
6316 that we're the same as coreutils.
6317 (alpha, beta, major): Depend on news-date-check.
6318 Make the upload commands.
6320 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
6321 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
6322 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
6323 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
6324 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
6325 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
6326 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
6327 * tests/sets.at: Likewise.
6329 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
6330 we comment out the Autoconf version number.
6331 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
6332 it's error-prone and "make maintainer-distcheck" rejects it.
6334 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
6335 Indent calls to "error" to pacify "make maintainer-distcheck",
6336 when the calls are not intended to be translated.
6337 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
6339 * src/Makefile.am (DEFS): Use +=, to pacify
6340 "make maintainer-distcheck".
6341 (bison_SOURCES): Add scan-skel.h.
6342 (sc_tight_scope): New rule, from coreutils.
6344 * src/files.c (src_extension, header_extension):
6345 Now static, not extern.
6346 * src/getargs.c (short_options): Likewise.
6347 * src/muscle_tab.c (muscle_table): Likewise.
6348 * src/parse-gram.y (current_class, current_type, current_prec):
6350 * src/reader.c (grammar_end, previous_rule_end): Likewise.
6351 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
6352 * src/main.c (main): Cast bindtextdomain and textdomain calls to
6353 void, to avoid warning when NLS is disabled.
6354 * src/output.c: Include scan-skel.h.
6355 (scan_skel): Remove decl, since scan-skel.h does this.
6357 Indent calls to "error" to pacify "make maintainer-distcheck".
6358 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
6359 * src/reader.h (gram_end, gram_lineno): New decls to pacify
6360 "make maintainer-distcheck".
6361 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
6362 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
6363 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
6364 (skel_lex_destroy, scan_skel): Move these decls to...
6365 * src/scan-skel.h: New file.
6366 * src/uniqstr.c (uniqstr_assert):
6367 Indent calls to "error" to pacify "make maintainer-distcheck".
6369 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
6372 * tests/torture.at: Revamp to avoid misuse of atoi that
6373 "make maintainer-distcheck" complained about.
6375 * examples/extexi (message): Don't print a message more than once,
6376 and omit line-number decoration that makes Emacs compile think
6377 that informative messages are worth worrying about.
6379 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
6381 * configure.ac: Update version number.
6383 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
6385 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
6386 autogenerated by the maintainer.
6387 * examples/calc++/.cvsignore: Add *.yy.
6389 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
6390 * lib/bitset_stats.c (bitset_stats_init): Likewise.
6391 * lib/bitsetv.c (bitsetv_alloc): Likewise.
6393 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
6395 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
6396 from maintainer-distcheck about casting the argument of 'free'.
6398 * NEWS: Mention recent yytname changes.
6399 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
6401 * bootstrap: For translations that have not yet been upgraded to
6402 the new runtime-po domain, prime the pump by extracting the
6403 relevant strings from the obsolete translations. This code can be
6404 removed once the bison-runtime domain has been translated by each
6407 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
6408 now that token names are already quoted.
6410 Fix problem reported by Anthony Heading.
6411 * data/glr.c (YYTOKEN_TABLE): New macro.
6412 (yytname): Define if YYTOKEN_TABLE.
6413 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
6414 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
6415 (YYERROR_VERBOSE): Define the same way the other skeletons do.
6416 * src/output.c (prepare_symbols): Output token_table_flag.
6418 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
6420 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
6421 again if the first call fails.
6423 * data/glr.c (yytnamerr): New function.
6424 (yyreportSyntaxError): Use it to dequote most string literals.
6425 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
6426 with other skeletons. All uses changed.
6427 (yytnameerr_): New function.
6428 (yyreport_syntax_error): Use it to dequote most string literals.
6429 * data/yacc.c (yytnamerr): New function.
6430 (yyerrlab): Use it to decode most string literals.
6431 * doc/bison.texinfo (Decl Summary, Calling Convention):
6432 Clarify quoting convention of yytname.
6433 * src/output.c (prepare_symbols): Quote all names. This undoes
6434 the 2005-04-17 change, which is now accomplished (mostly) via
6435 changes in the parsers as described above.
6436 * tests/regression.at (Token definitions, Web2c Actions):
6437 Undo most 2005-04-17 change here, too.
6439 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
6441 Fix more problems reported by twlevo@xs4all.nl.
6442 * tests/cxx-type.at: Don't pipe output of ./types through sed to
6443 remove trailing spaces. This loses the exit status of ./types,
6444 and isn't needed since ./types shouldn't be emitting trailing
6446 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
6447 as the stack isn't valid in that case.
6449 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6450 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6451 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6452 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
6454 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
6455 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
6456 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
6459 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
6460 overly-picky compilers that reject 'char *foo = "bar";'.
6462 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
6463 to FILE * parameter, not to stderr. This fixes a typo introduced
6464 in the 2005-07-12 change.
6466 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
6467 warnings from GCC 4.
6469 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
6470 (yyglrShiftDefer, yysplitStack):
6471 Remove unused parameters b4_pure_formals. All uses changed.
6472 (yyglrShift): Remove unused parameters b4_user_formals.
6474 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
6476 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
6478 Destructor cleanups and regularization among the three skeletons.
6479 * NEWS: Document the behavior changes.
6480 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
6481 stack before failing, as the cleanup code will do it for us now.
6482 * data/lalr1.cc (yyerrlab): Likewise.
6483 * data/glr.c (yyparse): Pop everything off the stack before
6484 freeing it, so that destructors get called properly.
6485 * data/lalr1.cc (yyreturn): Likewise.
6486 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
6487 This is more consistent.
6488 * doc/bison.texinfo (Destructor Decl): Mention more reasons
6489 why destructors might be called. 1.875 -> 2.1.
6490 (Destructor Decl, Decl Summary, Table of Symbols):
6491 Some English-language cleanups for %destructor.
6492 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6493 Add output line for destructor of start symbol.
6494 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
6495 because of that same extra output line.
6497 * NEWS: Document minor wording changes in diagnostics of
6498 Bison-generated parsers.
6499 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
6500 Remove unused formals. All uses changed.
6501 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
6502 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
6503 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
6504 Rename yyoverflowab to yyexhaustedlab.
6505 When memory exhaustion occurs during syntax-error reporting,
6506 report it separately rather than in a single diagnostic; this
6508 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
6509 (Memory Exhausted): Renamed from Parser Stack Overflow.
6510 Revamp wording slightly to prefer "memory exhaustion".
6511 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
6513 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
6515 Add i18n support to the GLR skeleton. Partially fix the C++
6516 skeleton; a C++ expert needs to finish this. Remove debugging
6517 msgids; there's little point to having them translated, since they
6518 can be understood only by someone who can read the
6519 (English-language) source code.
6521 Generate runtime-po/bison-runtime.pot automatically, so that we
6522 don't have to worry about garbage getting in that file. We'll
6523 make sure after the next official release that old msgids don't
6525 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
6527 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
6529 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
6530 Fix typos in explanations of the runtime file.
6531 * bootstrap: Change gettext keyword from YYI18N to YY_.
6532 Use standard Makefile.in.in in runtime-po, since we'll arrange
6533 for backward-compatible bison-runtime.po files in a different way.
6534 * data/glr.c (YY_): New macro, from yacc.c.
6535 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
6536 Translate messages intended for users.
6537 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
6538 the wording in the other skeletons. We don't know that the memory
6540 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
6541 Use same method that yacc.c uses.
6542 Don't translate debugging messages.
6543 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
6544 it doesn't work (yet), and requires C++ expertise to fix.
6545 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
6546 Move defn to a more logical place, to be consistent with other
6548 Don't translate debugging messages.
6549 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
6550 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
6551 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
6552 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
6554 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
6555 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
6557 * tests/glr-regression.at (Badly Collapsed GLR States):
6559 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6560 yylex should return 0 at EOF rather than aborting.
6562 Improve tests for stack overflow in GLR parser.
6563 Problem reported by twlevo@xs4all.nl.
6564 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
6566 (yyStackOverflow): Just longjmp, but with value 2 so that caller
6567 can handle the problem.
6568 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
6569 (yyparse): New local variable yyresult to record the result.
6570 Use result of setjmp to set it, rather than storing itinto
6572 (yyDone): Remove label.
6573 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
6574 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
6575 if YYABORT is used).
6576 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
6577 yyparse status; put status > 1 into diagnostic.
6578 Check that status==2 works.
6579 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
6580 Use exit status 3 for failure to open (which shouldn't happen).
6582 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
6584 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
6585 1 on syntax error; just let yyparse do its thing.
6586 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
6587 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
6588 (Exploding the Stack Size with Alloca):
6589 (Exploding the Stack Size with Malloc):
6590 Expect exit status 2, not 1, since the parser is supposed to blow
6591 its stack. Problem reported by twlevo@xs4all.nl.
6593 * data/glr.c (yyparse): Don't assume that the initial calls
6594 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
6595 Print a stack-overflow message and fail instead.
6596 Initialize the line-number information before creating the stack,
6597 so that the stack-overflow message can report line zero safely.
6599 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
6601 Fix problems reported by twlevo@xs4all.nl.
6602 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
6603 (yyuserMerge): Provide a default case if b4_mergers is empty.
6604 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
6605 * tests/glr-regression.at
6606 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
6607 Add casts to pacify C++ compilers.
6608 * tests/glr-regression.at (Improper merging of GLR delayed action
6609 sets): Declare yylex before using it.
6610 * tests/Makefile.am (maintainer-check-g++): Fix a stray
6611 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
6612 test for valgrind; valgrind is independent of g++.
6613 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
6614 for compatibility with POSIX 1003.1-2001 (if running coreutils).
6615 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
6616 Use a destructor, so that we can expand the stack. Change
6617 YYSTYPE to char * so that we can free it. Cast result of malloc.
6619 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
6621 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
6622 a valgrind failure. Problem reported by twlevo@xs4all.nl.
6624 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
6626 * PACKAGING: New file, suggested by Bruno Haible and taken from
6627 similar wording in gettext's PACKAGING file.
6628 * NEWS: Mention PACKAGING.
6629 * Makefile.am (EXTRA_DIST): Add PACKAGING.
6631 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
6633 * NEWS: Document recent i18n improvements.
6634 * bootstrap: Get runtime translations into runtime-po.
6635 Create runtime-po files automatically, if possible.
6636 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
6637 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
6638 does not infringe on the user's name space.
6639 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
6640 * doc/bison.texinfo (Internationalization): Revamp the English
6641 and Texinfo syntax a bit, to try to make it clearer.
6642 (Bison Options, Option Cross Key): Mention --print-localedir.
6643 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
6644 YYENABLE_NLS. Quote a bit more.
6645 * runtime-po/.cvsignore: New file.
6646 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
6647 * runtime-po/Rules-quot: Remove; now created by bootstrap.
6648 * runtime-po/quot.sed: Likewise.
6649 * runtime-po/boldquot.sed: Likewise.
6650 * runtime-po/en@quot.header: Likewise.
6651 * runtime-po/en@boldquot.header: Likewise.
6652 * runtime-po/insert-header.sin: Likewise.
6653 * runtime-po/remove-potcdate.sin: Likewise.
6654 * runtime-po/Makevars: Likewise.
6655 * runtime-po/LINGUAS: Likewise.
6656 * runtime-po/de.po: Likewise; we will rely on the translation project
6657 to maintain this, so "bootstrap" should get it.
6658 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
6660 * src/main.c (main): Bind the bison-runtime domain, too.
6662 2005-07-12 Bruno Haible <bruno@clisp.org>
6664 * data/yacc.c: Include <libintl.h> when NLS is enabled.
6665 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
6666 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
6667 * runtime-po: New directory.
6668 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
6669 $(DOMAIN).pot-update rule, so that old messages are never dropped.
6670 * runtime-po/Rules-quot: New file, copied from po/.
6671 * runtime-po/quot.sed: Likewise.
6672 * runtime-po/boldquot.sed: Likewise.
6673 * runtime-po/en@quot.header: Likewise.
6674 * runtime-po/en@boldquot.header: Likewise.
6675 * runtime-po/insert-header.sin: Likewise.
6676 * runtime-po/remove-potcdate.sin: Likewise.
6677 * runtime-po/Makevars: New file.
6678 * runtime-po/POTFILES.in: New file.
6679 * runtime-po/LINGUAS: New file.
6680 * runtime-po/bison-runtime.pot: New file.
6681 * runtime-po/de.po: New file.
6682 * m4/bison.m4: New file.
6683 * Makefile.am (SUBDIRS): Add runtime-po.
6684 (aclocaldir, aclocal_DATA): New variables.
6685 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
6687 * src/getargs.c (usage): Document --print-localedir option.
6688 (PRINT_LOCALEDIR_OPTION): New enum item.
6689 (long_options): Add --print-localedir option.
6690 (getargs): Handle --print-localedir option.
6691 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
6692 (Internationalization): New section.
6694 2005-07-12 Akim Demaille <akim@epita.fr>
6696 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
6697 for consistency with the rest of the code.
6698 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
6701 2005-07-12 Akim Demaille <akim@epita.fr>
6703 * src/parse-gram.y: Use %printer instead of YYPRINT.
6705 2005-07-12 Akim Demaille <akim@epita.fr>
6707 * src/symtab.h, src/symtab.c (symbol_print): New.
6708 * src/symlist.h, src/symlist.c (symbol_list_print): New.
6709 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
6711 2005-07-12 Akim Demaille <akim@epita.fr>
6713 * data/glr.c (b4_syncline): Fix (swap) the definitions of
6714 b4_at_dollar and b4_dollar_dollar.
6716 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
6718 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
6719 and Pennello's paper.
6721 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
6723 * data/yacc.c (yyparse): Undo previous patch. Instead,
6724 set yylsp[0] and yyvsp[0] only if the initial action
6725 sets yylloc and yylval, respectively.
6727 * data/yacc.c (yyparse): In the initial action, set
6728 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
6729 This avoids the use of undefined variables if the initial
6730 action does not set yylloc and/or yylval.
6732 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6734 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
6735 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
6736 Remove from CVS. These files are automatically generated.
6737 * examples/extexi: Clarify that this file is now part of Bison,
6738 not GNU M4, and that it works with any POSIX-compatible Awk.
6739 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
6740 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
6741 so that we also get calc++-parser.yy. Geneate it.
6742 Use $(AWK), not gawk, since any conforming Awk will do.
6743 Put comment before action, since older 'make' can't handle comment
6745 $(BUILT_SOURCES): List all built sources, not just some of them.
6746 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
6747 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
6748 $($(calc_sources_generated)): Remove unnecessary test for existence
6749 of target. (This had a shell syntax error anyway; a stray "x".)
6750 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
6752 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
6754 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
6755 implied by the other modules.
6757 2005-07-06 Akim Demaille <akim@epita.fr>
6759 Bind examples/calc++ to the package.
6760 * examples/calc++/Makefile: Remove, replaced by...
6761 * examples/calc++/Makefile.am: ... this new file.
6762 * examples/calc++/test: Remove input.
6763 * examples/calc++/compile: Remove.
6764 * examples/Makefile.am: New.
6765 * configure.ac, Makefile.am: Adjust.
6766 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
6768 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
6770 * data/glr.c (yyFail): Drastically simplify; since the format argument
6771 never had any % directives, we can simply pass it to yyerror.
6772 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
6773 be modified later, as that is the usual style in glr.c.
6774 Problems reported by Paul Hilfinger.
6776 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
6777 and size overflow errors.
6778 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
6779 in case the user prolog sets feature-test macros like _GNU_SOURCE.
6780 (YYSIZEMAX): New macro.
6781 (yystpcpy): New function, taken from yacc.c.
6782 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
6783 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
6784 so that we don't have to maintain their signatures.
6785 (yyFail): Check for buffer overflow, by using vsnprintf rather
6786 than vsprintf. Allocate a bigger buffer if possible.
6787 Report an error if buffer allocation fails.
6788 (yyStackOverflow): New function.
6789 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
6790 the initialization was successful. It might fail if storage was
6792 (yyexpandGLRStack): Add more checks for storage allocation failure.
6793 Use yyStackOverflow to report failures.
6794 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
6795 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
6796 Don't assume stack number fits in int.
6797 (yysplitStack): Check for storage allocation failure.
6798 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
6799 can print diagnostics on storage allocation failure. All callers
6801 (yyresolveValue): Use yybool for boolean.
6802 (yyreportSyntaxError): Check for size-calculation overflow.
6803 This code is taken from yacc.c.
6804 (yyparse): Check for storage allocation errors when allocating

6840 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
6841 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
6842 which stems from the 2005-05-27 patch.
6844 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
6846 * data/glr.c: Modify treatment of unused parameters to permit use
6847 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).

6859 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
6861 Fix infringement on user name space reported by Bruno Haible.
6862 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
6863 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
6864 the user's name space.
6865 (alloca): Include <stdlib.h> to get it, if it's not built in.
6866 (YYMALLOC, YYFREE): Define only if needed.
6867 (malloc, free): Declare, but only if needed, as this infringes on
6868 the user name space.
6870 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
6872 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
6873 * lib/bitset.c (bitset_print): Don't assume size_t can be printed

6888 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
6890 * bootstrap: Remove workaround for problem I encountered with
6891 gettext 0.14.1; it seems to be fixed now.

6895 * NEWS: Version 2.0a.
6897 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
6898 the previous change.
6900 Various maintainer cleanups.
6901 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
6902 conftest*, for benefit of CVS commands run at the same time as
6903 "configure". Add build-aux, since "bootstrap" now creates it and
6905 * Makefile.cfg (move_if_change): Remove.
6906 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
6907 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

6914 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
6915 this is now the recommended name.
6916 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
6917 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
6918 ylwrap. These files now go into build-aux.
6919 * config/move-if-change: Remove.
6920 * config/prev-version.txt: Bump from 1.75 to 2.0.
6922 * bootstrap: Add stdio-safer, unistd-safer modules.

6926 fopen-safer.c, stdio-safer.h, unistd-safer.h.
6927 * lib/subpipe.c: Include "unistd-safer.h".
6928 (create_subpipe): Make sure all the newly-created
6929 file descriptors are > 2, so that diagnostics don't
6930 get sent down them (which might cause Bison to hang, in theory).
6931 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
6932 * src/files.c (xfopen): Use fopen_safer, not fopen.
6934 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
6935 yesterday's yacc.c fix.
6937 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

6943 * data/yacc.c (yyabortlab): Don't call destructor, and
6944 don't set yychar to EMPTY.
6945 (yyoverflowlab): Don't call destructor.
6946 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
6947 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
6948 since we no longer output the message "discarding lookahead token
6951 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
6953 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
6954 fix a small glitch in debugging output.
6955 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
6956 after YY_SYMBOL_PRINT where needed.

7010 Problem reported by Ralf Menzel.
7012 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7014 * tests/actions.at: Test that stack overflow invokes destructors.
7015 From Marcus Holland-Moritz.
7016 * data/yacc.c (yyerrlab): Move the code that destroys the stack
7018 (yyreturn): to here. That way, destructors are called properly
7019 even if the stack overflows, or the user calls YYACCEPT or
7020 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
7021 (yyoverflowlab): Destroy the lookahead.
7023 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
7025 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
7027 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
7029 * NEWS: Bison-generated C parsers no longer quote literal strings
7030 associated with tokens.
7031 * src/output.c (prepare_symbols): Don't escape strings,
7032 since users don't want to see C escapes.
7033 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
7035 * tests/input.at (Torturing the Scanner): Likewise.
7036 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
7038 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
7040 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
7041 the data size is known to be too small and we can't increase it.
7042 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
7044 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
7046 * src/parse-gram.y: Include quotearg.h.
7047 (string_as_id): Quote $1 before using it as a key, since the
7048 lexer no longer quotes it for us.
7049 (string_content): Don't strip quotes, since lexer no longer
7051 * src/scan-gram.l: Include quotearg.h.
7053 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
7054 a key, since the rest of the lexer doesn't quote it.
7055 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
7056 * tests/regression.at (Token definitions): Check for backslashes
7059 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
7060 (YYSIZE_T): Define to unsigned long int when using an older compiler.
7061 (yyparse): Revamp code to generate long syntax error message, to
7062 make it easier to translate, and to avoid problems with arithmetic
7063 overflow. Change "virtual memory" to "memory" in diagnostic, since
7064 we don't know whether the memory is virtual.
7066 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7068 * NEWS: Bison-generated C parsers now use the _ macro to
7070 * data/yacc.c (_) [!defined _]: New macro.
7071 All English strings wrapped inside this macro.
7072 * doc/bison.texinfo (Bison Parser): Document _.
7073 * po/POTFILES.in: Include src/parse-gram.c, since it now
7074 includes translateable strings that parse-gram.y doesn't.
7076 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
7078 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
7079 reverting the 2004-10-11 change to this function.
7080 (symbol_check_alias_consistency): Don't call symbol_type_set
7081 if the type name is already correct.
7082 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
7084 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
7086 * tests/regression.at (Token definitions): Don't use a token named
7087 c, as that generates a "#define c ..." that runs afoul of buggy
7088 stdlib.h that uses the identifier c as a member of struct
7089 drand48_data. Problem reported by Horst Wente.
7091 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
7093 * bootstrap: Change translation URL from
7094 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
7095 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
7096 redirection glitches. Problem reported by twlevo@xs4all.nl.
7098 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
7100 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
7101 after operands; POSIX says this isn't portable for the c99 command.
7103 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
7105 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
7106 immediately if a data overrun has occurred; this may help us track
7107 down what may be a spurious failure on MacOS.
7109 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
7111 Respond to problems reported by twlevo@xs4all.nl.

7115 * src/vcg.h: Comment fix.
7116 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
7117 (G_CMAX): Change to -1 instead of INT_MAX.

7121 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
7123 * src/tables.c (state_number_to_vector_number): Put it inside an
7124 "#if 0", since it's not currently used. Problem reported by
7127 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
7129 * src/output.c (escaped_output): Renamed from
7130 escaped_file_name_output, since we now use it for symbol tags as
7131 well. All uses changed.
7132 (symbol_destructors_output, symbol_printers_output):
7133 Escape symbol tags too.
7134 Problem reported by Matyas Forstner in
7135 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
7137 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
7139 * src/output.c (user_actions_output, token_definitions_output,
7140 symbol_destructors_output, symbol_printers_output): Likewise.
7141 * src/reader.c (prologue_augment): Likewise.
7142 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
7144 * src/vcg.c (output_edge): Don't quote linestyle arg.
7145 Problem reported by twlevo@xs4all.nl.
7147 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
7149 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
7150 example, reported by Derek M Jones. Also, make the example even
7151 more outrageous, to better illustrate how bad the problem is.
7153 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
7155 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
7156 putsym. Typo reported by Sebastian Piping.
7158 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7160 * doc/bison.texinfo (Language and Grammar): some -> same
7161 (Epilogue): int he -> in the
7162 Typos reported by Sebastian Piping via Justin Pence.
7164 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7166 * tests/glr-regression.at (Improper handling of embedded actions
7167 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
7168 embedded actions and $-N in GLR parsers", work around an Autoconf bug
7169 with dollar signs in test names.
7170 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
7171 for a similar reason.
7173 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7175 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
7176 wants to redefine G_VIEW.
7178 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
7180 * src/vcg.c (get_view_str): Remove case for normal_view.

7186 Problem reported by twlevo@xs4all.nl.
7188 * doc/bison.texinfo: Change @dircategory from "GNU programming
7189 tools" to "Software development". Requested by Richard Stallman
7192 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
7194 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
7195 Problem reported by twlevo@xs4all.nl.
7197 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
7199 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
7200 keyword; it's not needed with modern compilers, and it doesn't
7201 affect correctness with older compilers. Suggested by
7204 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
7206 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
7207 gcc -Wswitch-default.

7216 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
7218 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
7219 for the benefit of slower hosts. Problem reported by
7222 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
7224 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
7225 being defined and not used.
7226 * data/lalr1.cc (yyparse): Likewise.
7227 Use "if (false)" rather than "if (0)".

7231 * TODO: Mention that we should allow NUL bytes in tokens.
7233 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
7235 * src/scan-skel.l (<<EOF>>): Don't close standard output.
7236 Problem reported by Hans Aberg.
7238 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
7240 * src/getargs.c (version): Happy new year; update overall
7241 program copyright date from 2004 to 2005.
7243 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
7244 Problem reported by Hans Aberg.
7245 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
7246 (Output file names.): Add a test for the case when standard output
7249 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
7251 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
7252 to fix an oversight in the Bison 2.0 manual.
7254 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
7256 * NEWS: Version 2.0. Reformat the existing news items since
7257 1.875, so that related items are grouped together.
7258 * configure.ac (AC_INIT): Bump version to 2.0.
7259 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
7261 * tests/torture.at (Exploding the Stack Size with Alloca): Set
7262 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
7263 otherwise, we're not testing alloca. Unfortunately there's no
7264 simple way to consult HAVE_ALLOCA here.
7266 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
7269 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
7270 hand. This avoids a warning about comparing int to size_t when
7271 GCC warnings are enabled.
7273 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
7275 * NEWS: Bison-generated parsers no longer default to using the
7276 alloca function (when available) to extend the parser stack, due
7277 to widespread problems in unchecked stack-overflow detection.
7278 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
7279 responsibility to set it to a positive value. This lets the user
7280 specify a value that is not a preprocessor constant.
7281 * data/yacc.c (YYMAXDEPTH): Likewise.
7282 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
7283 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
7284 to be a compile-time constant. However, explain the constraints on it.
7285 Also, explain the constraints on YYINITDEPTH.
7286 (Table of Symbols): Explain that alloca is no longer the default.
7287 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
7290 * doc/bison.texinfo (Location Default Action): Mention that n must
7291 be zero when k is zero. Suggested by Frank Heckenbach.
7293 2004-12-22 Akim Demaille <akim@epita.fr>
7295 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
7296 (parser::state_type, parser::semantic_type, parser::location_type):
7297 Private, not public.
7298 (parser::parse): Return ints, not bool.
7299 Returning a bool introduces a problem: 0 corresponds to false, and
7300 it seems weird to return false on success. Returning true changes
7301 the conventions for yyparse.
7302 Alternatively we could return void and send an exception.
7303 There is no clear consensus (yet?).
7304 (state_stack, semantic_stack, location_stack): Rename as...
7305 (state_stack_type, semantic_stack_type, location_stack_type): these.
7306 Private, not public.

7308 * tests/testsuite.at, tests/Makefile.am: Adjust.
7310 2004-12-21 Akim Demaille <akim@epita.fr>
7312 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
7314 2004-12-21 Akim Demaille <akim@epita.fr>
7316 Don't impose std::string for filenames.
7318 * data/lalr1.cc (b4_filename_type): New.
7319 (position::filename): Use it.
7320 (parser.hh): Move the inclusion of stack.hh and location.hh below
7321 the user code, so that needed headers for the filename type can be
7323 Forward declare them before the user code.
7324 * tests/Makefile.am (check-local, installcheck-local): Pass
7325 TESTSUITEFLAGS to the TESTSUITE.
7327 2004-12-20 Akim Demaille <akim@epita.fr>
7329 Use more STL like names: my_class instead of MyClass.
7331 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
7332 (SemanticStack, SemanticType, StateStack, StateType)
7333 (TokenNumberType, Stack, Slice, Traits, Parser::location)
7334 (Parser::value): Rename as...
7335 (location_stack, location_type, rhs_number_type, semantic_stack)
7336 (semantic_type, state_stack, state_type, token_number_type, stack)
7337 (slice, traits, parser::yylloc, parser::yylval): these.
7339 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
7341 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
7343 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
7344 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
7346 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
7348 Remove uses of 'short int' and 'unsigned short int'. This raises
7349 some arbitrary limits. It uses more memory but nowadays that's
7350 not much of an issue.
7352 This change does not affect the generated parsers; that's a different
7353 task, as some users will want to conserve memory there.
7355 Ideally we should use size_t to represent all object counts, and
7356 something like ptrdiff_t to represent signed differences of object
7357 counts; but that will require more code-cleanup than I have the
7358 time to do right now.
7360 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
7361 Use size_t, not int or short int, to count objects.
7362 * src/closure.c (nritemset, closure): Likewise.
7363 * src/closure.h (nritemset, closure): Likewise.

7374 errs, reductions): Likewise.

7377 * src/tables.c (vector_number, tally, action_number,
7378 ACTION_NUMBER_MINIMUM): Likewise.
7379 * src/output.c (muscle_insert_short_int_table): Remove.
7381 2004-12-17 Akim Demaille <akim@epita.fr>
7383 * data/lalr1.cc: Extensive Doxygenation.
7384 (error_): Rename as...
7385 (error): this, since it is visible to the user.
7387 (Parser::message): Now an automatic variable from...
7388 (Parser::yyreport_syntax_error_): here.
7389 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
7391 * tests/input.at: Escape $.
7393 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
7395 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
7396 Parenthesize rhs to avoid obscure problems with mistakes like
7397 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
7398 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
7399 b4_rhs_location): Likewise.

7401 b4_rhs_location): Likewise.
7403 2004-12-16 Akim Demaille <akim@epita.fr>
7405 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
7406 yacc.c: be sure to stay within yycheck_.
7407 * tests/actions.at: Re-enable C++ tests.
7409 2004-12-16 Akim Demaille <akim@epita.fr>
7411 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
7414 2004-12-16 Akim Demaille <akim@epita.fr>
7416 Use #define to handle the %name-prefix.
7418 * data/glr.c, data/yacc.c: Comment changes.
7419 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
7420 so that one can refer to yylex in the parser file, and have it
7421 renamed, as is the case with other skeletons.
7423 2004-12-16 Akim Demaille <akim@epita.fr>

7445 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
7447 Fix some problems reported by twlevo at xs4all.
7448 * src/symtab.c (symbol_new): Report an error if the input grammar
7449 contains too many symbols. This is better than calling abort() later.
7450 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
7451 (struct node, struct graph):
7452 Rename member expand to stretch. All uses changed.
7453 (struct graph): Remove member layoutalgorithm. All uses removed.

7468 2004-12-15 Akim Demaille <akim@epita.fr>
7470 * data/lalr1.cc (lex_): Rename as...
7472 Move the trace here.
7473 Take the %name-prefix into account.
7474 Reported by Alexandre Duret-Lutz.
7476 2004-12-15 Akim Demaille <akim@epita.fr>
7478 Simplify the C++ parser constructor.
7480 * data/lalr1.cc (debug_): Rename as...
7481 (yydebug_): so that the parser's internals are always in the yy*
7484 (b4_parse_param_decl): Remove the leading comma as it is now only
7485 called as unique argument list.
7486 (Parser::Parser): Remove the constructor accepting a location and
7487 an initial debugging level.

7491 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
7494 2004-12-15 Akim Demaille <akim@epita.fr>
7496 Remove b4_root related material: failure experiment
7497 (which goal was to allow to derive from a class).
7499 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
7500 definitions and uses.
7502 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
7504 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
7505 not 2, since it's not portable to subtract 1 from the start of an
7506 array. The new item 0 is never set or used. All uses changed.
7508 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
7509 the default definition of YYLLOC_DEFAULT. Problem reported
7510 by Frank Heckenbach.
7512 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
7514 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
7515 the normal case and one for the error case. Just use the
7516 first one uniformly. Problem reported by Frank Heckenbach.
7517 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
7518 use exactly the same macro in both places.
7519 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
7520 so that the normal-case YYRHSLOC works for the error case too.
7522 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
7523 (YYLLOC_DEFAULT): Use the same macro as glr.c.
7524 * doc/bison.texinfo (Location Default Action): Don't claim that
7525 we have an array of locations. Use the same macro for both glr
7526 and lalr parsers. Mention YYRHSLOC. Mention what happens when

7538 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
7540 * src/scan-skel.l: Include "complain.h", for "fatal".
7542 * src/relation.h (relation_print, relation_digraph):
7543 Relation sizes are of type relation_node, not size_t (this is
7544 merely a doc fix, since the two types are equivalent).
7545 (relation_transpose): Relation sizes are of type relation_node,
7547 * src/relation.c: Likewise.
7548 (top, infinity): Now of type relation_node, not int.
7549 (traverse, relation_transpose): Use relation_node, not int.
7551 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
7552 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
7553 (yyparse): Remove unused local introduced in 2004-10-25 patch.
7555 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
7556 specifying whether the test should be skipped. Use it tp
7557 specify that the [%defines %skeleton "lalr1.cc"] tests currently
7558 fail on some hosts, and should be skipped.
7560 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
7562 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
7563 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
7564 unless otherwise specified below.
7566 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
7567 to allocate kernel_base, kernel_items, kernel_size, since
7568 they needn't be initialized to 0.

7586 (goto_actions): Likewise for state_count.
7587 (pack_table): Likewise for base, pos, check.
7588 (tables_generate): Likewise for width.
7590 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
7591 for initial core. Just have a separate core, so we needn't worry
7592 about whether kernel_size and kernel_base are initialized.
7594 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
7595 kernel_size, kernel_items): Remove unnecessary initialization.

7601 conflrow, conflict_table, conflict_list, table, check):
7604 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
7605 This is because all callers pass unsigned int.
7606 * src/closure.h (new_closure): Likewise.
7608 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
7609 (build_relations): Initialize includes[i] in all cases.

7611 and rules[ruleno].precsym. Initialize members in order.

7614 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
7616 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
7617 conflict_list[0] was always 0, but now it isn't initialized.
7619 * src/table.c (table_grow): When conflict_table grew, the grown
7620 area wasn't cleared. Fix this.
7622 * lib/.cvsignore: Add strdup.c, strdup.h.

7625 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
7627 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
7628 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
7629 GOTO_NUMBER_MAXIMUM, since we occasionally compute
7630 ngotos + 1 without checking for overflow.
7631 (build_relations): Use END_NODE, not -1, to denote end of edges.
7632 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
7633 build_relations): Use goto_number, not int, for goto numbers.

7638 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
7639 of #defining from yystype.
7640 Don't typedef yystype, C++ does not need it.
7641 This lets it possible to forward declare it as union.
7643 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
7645 * bootstrap (gnulib_modules): Add extensions.
7646 Problem reported by Jim Meyering.

7692 have an accurate range, equivalent to the one computed by both
7693 yacc.c and lalr1.cc.
7694 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
7695 that column numbers start at column 0, as per GNU Coding
7696 Standards, the others tests, and the doc.
7697 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
7698 Adjust to the above change (first column is 0).

7705 Remove some arbitrary limits on goto numbers and relations.
7706 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
7707 initial values, since they're never used.
7708 (set_goto_map): ngotos is now unsigned, so test for overflow
7709 by seeing whether it wraps around to zero.
7710 * src/lalr.h (goto_number): Now size_t, not short int.
7711 (GOTO_NUMBER_MAXIMUM): Remove.
7712 * src/relation.c (relation_print, traverse, relation_transpose):
7713 Check for END_NODE rather than looking at sign.
7714 * src/relation.h (END_NODE): New macro.
7715 (relation_node): Now size_t, not short int.
7717 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
7719 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
7720 keyword, not an identifier. Problem reported by Baron Schwartz in
7721 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
7723 2004-10-11 Akim Demaille <akim@epita.fr>
7725 * src/symtab.c (symbol_check_alias_consistency): Also check
7726 type names, destructors, and printers.
7727 Reported by Alexandre Duret-Lutz.
7728 Recode the handling of associativity and precedence in terms
7729 of symbol_precedence_set.
7730 Accept no redeclaration at all, not even equal to the previous
7732 (redeclaration): New.
7733 Use it to factor redeclaration complaints.
7734 (symbol_make_alias): Don't set the type of the alias, let
7735 symbol_check_alias_consistency do it as for other features.
7736 * src/symtab.h (symbol): Add new member prec_location, and
7738 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
7739 * tests/input.at (Incompatible Aliases): New.
7741 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
7743 .cvsignore fixes to accommodate gnulib changes,
7744 and the practice of naming build directories "_build".
7745 * .cvsignore: Add "_*". Sort.
7746 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
7747 * m4/.cvsignore: Add "*_gl.m4".
7749 2004-10-06 Akim Demaille <akim@epita.fr>
7751 * src/parse-gram.y (add_param): Fix the truncation of trailing
7754 2004-10-05 Akim Demaille <akim@epita.fr>
7756 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
7757 whether the reducion was empty or not. This leaves room to
7758 improve the use of YYLLOC_DEFAULT in such a case.
7759 lalr1.cc is still experimental, so changing this is acceptable.
7760 And finally, there are probably not many users who changed the
7761 handling of locations in GLR, so changing is admissible too.
7763 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
7764 empty reduction, set @$ to an empty location ending the previously
7766 Adjust uses to make sure the code is triggered on empty
7768 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
7769 expected output: empty reductions have empty locations.
7771 2004-09-29 Akim Demaille <akim@epita.fr>
7773 * data/lalr1.cc: Move towards a more standard C++ coding style
7774 for templates: Class < T > -> Class<T>.
7776 2004-09-29 Akim Demaille <akim@epita.fr>
7778 * data/lalr1.cc: Reinstall the former ctor, for sake of
7779 compatibility, but warn it will be removed.
7780 Move towards a more standard C++ coding style (i.e., type *var ->
7783 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
7785 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
7786 since it's less likely to work if NULs are involved in the future.
7788 2004-09-27 Akim Demaille <akim@epita.fr>
7790 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
7792 2004-09-27 Akim Demaille <akim@epita.fr>
7794 * data/lalr1.cc (b4_parse_param_decl_1): New.
7795 (b4_parse_param_decl): Use it to have different names between attribute
7797 (b4_cc_constructor_call): Likewise.
7799 2004-09-24 Akim Demaille <akim@epita.fr>
7801 * src/parse-gram.y (add_param): Strip the leading and trailing
7802 blanks from a formal argument declaration.
7803 (YY_LOCATION_PRINT): New.
7805 2004-09-24 Akim Demaille <akim@epita.fr>
7807 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
7810 2004-09-24 Akim Demaille <akim@epita.fr>
7812 * doc/bison.texinfo (Table of Symbols): Sort.
7814 2004-09-21 Akim Demaille <akim@epita.fr>
7816 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
7817 the useless parentheses.
7818 Suggested by Paul Eggert.
7820 2004-09-20 Akim Demaille <akim@epita.fr>
7822 Let the initial-action act on the look-ahead, and use it for the
7823 "initial push" (corresponding to an hypothetical beginning-of-file).
7824 And let lalr1.cc honor %initial-action.
7826 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
7828 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
7829 (Parser::Parser): Remove the ctor that used to initialize it.
7830 (Parser::parse): Like in the other skeletons, issue the "starting
7831 parse" message before any action.
7832 Honor %initial-action.
7833 Initialize the stacks with the lookahead.
7834 * data/yacc.c: Let $$ and @$ in %initial-action designate the
7836 Push them in the stacks.
7837 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
7839 2004-09-20 Akim Demaille <akim@epita.fr>
7841 * doc/bison.texinfo (Initial Action Decl): New.
7843 2004-09-20 Akim Demaille <akim@epita.fr>
7845 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
7846 clearer criterion to define it.
7847 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
7848 When reducing on an empty RHS, use the latest stacked location as
7850 yylloc is not always available.
7851 * data/glr.c: Likewise.
7852 Also, honor initial-actions.
7854 2004-09-20 Akim Demaille <akim@epita.fr>
7856 * data/yacc.c (YY_LOCATION_PRINT): New.
7857 Define when we know YYLTYPE's structure, i.e., when the default
7858 YYLLOC_DEFAULT is used.
7859 * data/c.m4 (b4_yysymprint_generate): Use it.
7860 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
7861 value of the result.
7862 (error_start_): Replace with...
7863 (error_range_): this location array.
7864 This allows to replace code relying on the implementation of
7865 locations by portable code.
7866 * data/yacc.c (yylerrsp): Replace with...
7867 (yyerror_range): this.
7868 Every time a token is popped, update yyerror_range[0], to have an
7869 accurate location for the error token.
7870 * data/glr.c (YY_LOCATION_PRINT): New.
7871 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
7872 deference a pointer.
7873 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
7874 report the location in %printers.
7876 * src/scan-skel.l: Instead of abort, report error messages to ease
7877 understanding skeleton scanning failures.
7879 2004-09-16 Akim Demaille <akim@epita.fr>
7881 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
7882 (iterator, const_iterator): these, to be more in the C++ spirit.
7883 Also, return reverse iterators so that when displaying the stack
7884 we display its bottom first.
7885 (Parser::stack_print_, Parser::reduce_print_): Match the messages
7887 We should probably use vector here though.
7889 2004-09-16 Akim Demaille <akim@epita.fr>
7891 Have more complete shift traces.
7893 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
7894 to report Shifts instead of ad hoc YYDPRINTF invocations,
7895 including for the error token.
7896 * data/lalr1.cc (symprint_): Output the location.
7897 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
7898 output the location within the %printer.
7899 Activate GLR tests, at least to make sure they compile properly.
7900 They still don't pass though.
7901 * tests/calc.at: Adjust expect verbose output, since now "Entering
7902 state..." is on a different line than the "Shifting" message.
7904 2004-09-08 Akim Demaille <akim@epita.fr>
7906 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
7907 Bison directive from the Bison file to the invocation of this
7908 macro, so that these directives are passed to
7909 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
7910 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
7911 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
7912 the extra Bison directives instead of the whole series.
7913 Change the grammar so that there are recoverable errors, and
7914 unrecoverable errors. Now we can have the parser give up before
7915 consuming the whole input. As a result we now can observe that
7916 the lookahead is freed when needed.
7917 Change the parser source to parse argv[1] instead of a hard coded
7919 Simplify yylex, and give a value and location to EOF.
7920 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
7921 passed directives already coded in the file.
7922 Add some tests to check the location of "error".
7923 For some tests, the C++ parser is correct, and not yacc.c.
7924 For other tests, they provide different, but unsatisfying, values,
7925 so keep the C++ value so that at least one parser is "correct"
7926 according to the test suite.
7927 (Actions after errors): Remove, this is subsumed by the
7928 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
7930 2004-09-06 Akim Demaille <akim@epita.fr>
7932 * data/lalr1.cc: Adjust the indentation of the labels.
7936 2004-09-06 Akim Demaille <akim@epita.fr>
7938 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
7939 argument, an informative message.
7940 Call YY_SYMBOL_PRINT.
7941 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
7942 * data/lalr1.cc (destruct_): Likewise.
7943 In addition, no longer depend on b4_yysymprint_generate and
7944 b4_yydestruct_generate to generate these functions, do it "by
7947 2004-09-03 Akim Demaille <akim@epita.fr>
7949 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
7950 invoked, yydestruct the lookahead.
7951 * tests/calc.at (Calculator $1): Update the expected lengths of
7952 traces: there is an added line for the discarded lookahead.
7953 * doc/bison.texinfo (Destructor Decl): Some rewording.
7954 Define "discarded" symbols.
7956 2004-09-02 Akim Demaille <akim@epita.fr>
7958 * data/lalr1.cc (translate_, destruct_): No reason to be static.
7960 2004-09-02 Akim Demaille <akim@epita.fr>
7962 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
7963 (YYDSYMPRINTF): Rename as...
7964 (YY_SYMBOL_PRINT): this.
7965 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
7967 Use it instead of direct symprint_ calls.
7968 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
7971 2004-09-02 Akim Demaille <akim@epita.fr>
7973 * data/lalr1.cc (b4_yysymprint_generate): New.
7974 (symprint_): New member function, defined when YYDEBUG.
7975 Use it consistently instead of token/nterm debugging output by
7977 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
7978 %printer calls to use cdebug_ when using lalr1.cc.
7980 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
7982 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
7983 with #ifdef YYDEBUG.
7985 2004-08-26 Akim Demaille <akim@epita.fr>
7987 * doc/bison.texinfo (Implementing Loops): Rename as...
7988 (Implementing Gotos/Loops): this.
7990 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
7992 Adjust to latest gnulib.
7993 * bootstrap (gnulib_modules): Add xalloc-die.
7994 Set LC_ALL=C so that file names sort consistently.
7995 Prefer the gnulib copies of gettext.m4, glibc21.m4,
7996 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
7997 uintmax_t.m4, ulonglong.m4.
7998 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
7999 po.m4 since we are now using _gl.m4 instead.
8001 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
8003 * src/scan-action.l: Remove. Scanning of semantic actions is
8004 handled in scan-gram.l.
8006 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
8008 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
8010 * src/location.h (struct): The file member is a uniqstr.
8011 (equal_boundaries): Use UNIQSTR_EQ for comparison.
8013 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
8015 Fix bug with non-%union parsers that have printers or destructors,
8016 which led to a Bison core dump. Reported by Peter Fales in
8017 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
8019 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
8020 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
8021 not to our own type.
8022 * src/output.c (symbol_destructors_output, symbol_printers_output):
8023 Don't assume %union.
8024 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
8025 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
8026 UNION-FLAG. All callers changed.
8027 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
8028 Use type char, not unsigned int, when declaring an array of char;
8029 this lets us remove a cast.
8030 (Printers and Destructors): Add non-%union test cases.
8032 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8034 * doc/bison.texinfo: Minor editorial changes, mostly to the new
8035 GLR writeups. E.g., avoid frenchspacing and the future tense,
8036 change "lookahead" to "look-ahead", and change "wrt" to "with
8039 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8041 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
8042 New sections, split off from the GLR Parsers section. Put the new
8043 Simple GLR Parser near the start of the GLR section, for clarity.
8044 Rewrite connective text.
8046 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
8048 * doc/bison.texinfo (Simple GLR Parsers): New section.
8050 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8052 * NEWS, TODO, doc/bison.texinfo:
8053 Use "look-ahead" instead of "lookahead", to be consistent.
8054 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
8055 while we're fixing "look-ahead".
8056 * src/conflicts.c (shift_set): Renamed from shiftset.
8057 (look_ahead_set): Renamed from lookaheadset.
8058 * src/print.c: Likewise.

8077 * README: Update location of patched M4 distribution.
8079 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
8081 Don't assume the C++ compiler takes the same arguments as the C compiler
8083 * configure.ac (O0CXXFLAGS): New var.
8084 * tests/atlocal.in (CXXFLAGS): Use it.
8086 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
8088 Fix some "make check" problems with C++ reported by
8089 Albert Chin-A-Young for Tru64 C++ in this thread:
8090 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
8092 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
8093 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8094 Output to a .cc file for C++, not to a .c file.

8097 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
8099 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
8101 * tests/calc.at, tests/actions.at: Workaround for SGI
8102 C++ compiler. (trivial change)
8104 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
8106 Spent a few hours checking out which prerequisite versions the
8107 current sources actually require. I went all the way back to
8108 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8109 a seemingly endless set of combinations of versions more recent
8110 than that. The bottom line is that the current sources require
8111 fairly recent versions of the build tools, and it'll be some work
8113 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
8114 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
8115 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
8116 Add comments explaining why those particular versions are
8119 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
8120 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
8121 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
8123 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
8124 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
8126 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8128 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
8129 0.11.5. Suggested by Bruno Haible.
8130 * bootstrap: Remove gettext version checking.
8132 * doc/bison.texinfo (Decl Summary): Also mention that %union
8133 can depend on prerequisite types. Problem reported by Tim
8136 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8138 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
8139 * README-alpha: Don't tell people not to package this.
8141 * bootstrap: Don't assume $(...) works; use `...` instead.
8142 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
8145 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
8146 put into the -d output file, and mention what to do if YYSTYPE is
8149 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8151 Undo change made earlier today: it caused autopoint to not bring
8152 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
8155 * bootstrap: Check that gettext version matches what's in
8156 configure.ac. Warn users to ignore robots.txt ERROR 404.
8157 * bootstrap: Undo today's earlier change (logged below).
8158 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
8160 The gettext version checking is causing more trouble than it's
8161 curing; remove it. Problem reported by Paul Hilfinger.
8163 * bootstrap: Issue a warning that one can expect a message
8164 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
8165 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
8167 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
8169 Ensure that the C++ compiler used for testing actually works on a
8170 simple test program; if not, skip the C++-related tests. Problem
8171 reported by Vin Shelton in:
8172 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
8174 * m4/cxx.m4: New file.
8175 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
8176 * tests/atlocal.in (BISON_CXX_WORKS): Add.
8177 * tests/local.at (AT_COMPILE_CXX): Use it.
8179 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
8181 * data/glr.c (yylloc): Output this macro even if locations are not
8182 being generated, as the GLR parser needs it even in that case.
8183 Problem reported by Troy A. Johnson
8184 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
8186 * configure.ac (AC_INIT): Update to 1.875e.
8188 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
8190 * NEWS: Version 1.875d.
8191 * configure.ac (AC_INIT): Likewise.

8194 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
8195 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current

8197 supported by GCC 3.4.0.
8198 * README: Mention GNU m4 1.4 or later; mention m4 patches.
8199 * HACKING: Use ./bootstrap, not "make update" to import foreign files.

8215 character and string literals.
8216 (unexpected_end): New function.
8217 (unexpected_eof): Use it.

8237 * src/.cvsignore: Add *.output.
8239 * src/parse-gram.y: Put copyright notice inside %{ %} so it
8240 gets copied to the output file.
8242 2004-04-28 Paul Eggert <eggert@twinsun.com>
8244 Get files from the gnulib and po repositories, instead of relying
8245 on them being in our CVS. Upgrade to latest versions of gnulib
8248 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
8249 * bootstrap: Bootstrap from gnulib and po repositories.
8250 Much of this code was stolen from GNU diff and GNU tar's bootstrap.

8279 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):

8315 Remove, as these files are now generated automatically
8316 by bootstrap or automake.

8342 support it. (The latest stable gzip doesn't.)
8344 2004-04-27 Paul Eggert <eggert@twinsun.com>
8346 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this

8375 so that this include file can stand alone.
8376 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
8377 does this now. Include subpipe.h first after config.h, to
8378 test whether it can stand alone.
8380 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
8381 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
8384 * tests/synclines.at (%union synch line): Put a dummy member in
8385 the union, because empty unions aren't allowed in C. Caught
8388 2004-04-13 Jim Meyering <jim@meyering.net>
8390 * src/conflicts.c (conflicts_print): Correct format string typo:

8494 it can be called with `%skeleton "lalr1.cc"', and do that.
8496 2004-02-02 Paul Eggert <eggert@twinsun.com>
8498 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
8499 $(top_srcdir)/lib and ../lib. This fixes a bug reported
8500 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.

8503 (INCLUDES): Remove, as Automake says it's obsolescent.
8504 Contents migrated into AM_CPPFLAGS as described above.

8521 * src/output.c (output_skeleton): Rename local var.
8522 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
8523 Bison tokens, as this runs afoul of the 2003-10-07 change that
8524 disallowed NUL bytes in character constants or string literals.
8526 * tests/local.at: Require Autoconf 2.59's Autotest.
8527 * tests/testsuite.at: Don't include local.at, since we now assume
8528 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
8530 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
8531 multiple inclusion warnings.

8551 Complain about NUL bytes in character constants or string literals.
8553 2003-10-05 Paul Eggert <eggert@twinsun.com>
8555 * NEWS: Don't document %no-default-prec, as it's still
8557 * doc/bison.texinfo: Document %no-default-prec only if
8558 the defaultprec flag is set. Normally it's not.
8560 2003-10-04 Paul Eggert <eggert@twinsun.com>
8562 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
8563 non-modifiable lvalue, instead of a modifiable one.
8564 * doc/bison.texinfo (Actions): Document that $$ can
8565 be assigned to. Do not claim that $$ and $N are
8566 array element references: user code should not rely on this.

8624 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
8626 2003-08-25 Akim Demaille <akim@epita.fr>
8628 When reducing initial empty rules, Bison parser read an initial
8629 location that is not defined. This results in garbage, and that
8630 affects Bison's own parser. Therefore we need (i) to extend Bison
8631 to support a means to initialize this location, and (ii) to use
8632 this CVS Bison to fix CVS Bison's parser.
8634 * src/reader.h, reader.c (epilogue_augment): Remove, replace
8636 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
8637 * src/parse-gram.y: Adjust.
8638 (%initial-action): New.
8639 (%error-verbose): Since we require CVS Bison, there is no reason
8641 * src/scan-gram.l: Adjust.
8642 * src/Makefile.am (YACC): New, to make sure we use our own parser.
8643 * data/yacc.c (yyparse): Use b4_initial_action.
8645 2003-08-25 Akim Demaille <akim@epita.fr>
8647 * doc/bison.texinfo: Don't promote stdout for error messages.
8649 2003-08-25 Akim Demaille <akim@epita.fr>
8651 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.

8658 2003-08-25 Akim Demaille <akim@epita.fr>
8660 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
8663 2003-08-25 Akim Demaille <akim@epita.fr>
8665 * data/lalr1.cc (Parser::reduce_print_): New.
8668 2003-08-25 Akim Demaille <akim@epita.fr>
8670 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
8671 error recovery loops. This patch is based on
8672 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
8673 Also, augment the similarity between lalr1.cc and yacc.c.
8674 Note: the locations of error recovery rules are not correct yet.
8676 * data/lalr1.cc: Comment changes to augment the similarity between
8677 lalr1.cc and yacc.c.
8678 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
8679 (yyerrlab1): Remove, but where it used to be (now the bottom part of
8680 yyerrlab), when hitting EOF, pop the whole stack here instead of
8681 merely falling thru the default error handling mechanism.
8682 (yyerrorlab): New label, with the old contents of YYERROR,
8683 plus the following change: pop the stack of rhs corresponding
8684 to the production that invoked YYERROR. That is how Yacc
8685 behaves (required by POSIX).
8686 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
8689 2003-08-25 Akim Demaille <akim@epita.fr>
8691 Tune local.at so that people can "autom4te -l autotest calc.at -o
8692 calc" for instance, to extract a sub test suite.
8694 * tests/testsuite.at: Move the initialization, Autotest version
8695 requirement, and AT_TESTED invocation into...
8696 * tests/local.at: here.
8697 * tests/testsuite.at: Include it for compatibility with Autoconf
8699 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
8702 2003-08-04 Paul Eggert <eggert@twinsun.com>
8704 Rework code slightly to avoid gcc -Wtraditional warnings.
8705 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
8706 The returned value is now stored in *YY0. All callers changed.
8707 * src/output.c (merge_output): Adjust to the above change.
8709 2003-07-26 Paul Eggert <eggert@twinsun.com>
8711 * data/glr.c (YYASSERT): New macro.
8712 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
8713 yyresolveStates, yyprocessOneStack):
8714 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
8715 Derived from a suggestion by Frank Heckenbach.
8717 2003-07-25 Paul Eggert <eggert@twinsun.com>
8719 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
8720 for portability to K&R C (after ansi2knr, presumably). See
8721 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
8722 by Frank Heckenbach, though I have omitted the structure-initialization
8723 part of his glr-knr.diff patch since I recall that the Portable
8724 C Compiler didn't require that change.
8726 Let the user specify how to allocate and free memory.
8727 Derived from a suggestion by Frank Heckenbach in
8728 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
8729 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
8730 All uses of free, malloc, realloc changed to use these macros,
8731 and unnecessary casts removed.
8732 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
8734 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
8736 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
8737 use s.empty() rather than s == "" to test for empty string; see

8750 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8751 Remove unnecessary parentheses from uses.

8757 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
8758 yyreportTree): Do not assume that size_t is the same width as int,
8759 when printing sizes. Print sizes using an unsigned format.
8760 Problem reported by Frank Heckenbach in
8761 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
8763 Port to Forte Developer 7 C compiler.
8764 * data/glr.c (struct YYLTYPE): If locations are not being used,
8765 declare a single dummy member, as empty structs do not conform
8767 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
8768 the Forte Developer 7 C compiler complains that end-of-loop
8769 code is not reached.
8771 2003-06-17 Paul Eggert <eggert@twinsun.com>
8773 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to

8787 per recent gettext manual's suggestion.
8788 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

8807 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
8808 * lib/vbitset.c, lib/vbitset.h: New files.
8809 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
8810 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
8813 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
8814 `How Can I Reset @code{yyparse}', since texinfo does not allow
8815 arbitrary @ in node names.
8817 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
8818 shouldn't be needed according to the gettext 0.12.1 documentation
8819 but which seem to be needed anyway: codeset.m4 glibc21.m4
8820 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
8821 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

8833 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
8834 (MOSTLYCLEANFILES): New var.
8835 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
8836 (stdbool.h): New rule.

8842 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
8843 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
8844 the tests right now.
8845 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
8846 yyerror are declared before use; C99 requires this.
8848 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8850 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
8852 (yyrecoverSyntaxError): Correct the logic for setting and testing
8854 Correct comment on handling EOF.
8855 Allow states with only a default reduction, rather than failing
8856 (I can't quite reconstruct why these were not allowed before).
8858 Fixes to avoid problem that $-N rules in GLR parsers can cause
8859 buffer overruns, corrupting state.
8861 * src/output.c (prepare_rules): Output max_left_semantic_context
8863 * src/reader.h (max_left_semantic_context): New variable declaration.
8864 * src/scan-gram.l (max_left_semantic_context): Define.

8868 (yyresolveAction): Ditto.
8870 Fixes to problems with location handling in GLR parsers reported by
8871 Frank Heckenbach (2003/06/05).
8873 * data/glr.c (YYLTYPE): Make trivial if locations not used.
8874 (YYRHSLOC): Add parentheses, and define only if locations used.
8875 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if

8878 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
8880 * tests/cxx-type.at: Exercise location information; update tests
8881 to differentiate output with and without locations.
8882 Remove forward declarations of yylex and yyerror---caused errors
8883 because default YYLTYPE not yet defined.
8884 Change semantic actions to compute strings, rather than printing
8885 them directly (to test proper passing of semantics values). Change
8886 output to prefix notation and update test data and expected results.
8887 (yylex): Track locations.
8888 (stmtMerge): Return value rather than printing, and include arguments
8891 2003-06-03 Paul Eggert <eggert@twinsun.com>
8893 Avoid warnings generated by GCC 2.95.4 when Bison is
8894 configured with --enable-gcc-warnings.

8899 yy::Slice::operator[] (unsigned),
8900 yy::Slice::operator[] (unsigned) const):
8901 Rename local vars to avoid warnings.
8902 * tests/glr-regression.at (Improper handling of embedded actions
8903 and $-N in GLR parsers): Remove unused local variable from yylex.
8904 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
8905 (void) as arg when not pure, since we now assume C89 when building
8906 Bison. Pacify GCC by using parameter.
8908 2003-06-02 Paul Eggert <eggert@twinsun.com>
8910 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
8911 yy::Location::lines, yy::Location::columns): Rename arguments
8912 to avoid shadowing; this removes a warning generated by GCC 3.3.
8914 2003-06-01 Paul Eggert <eggert@twinsun.com>
8916 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
8917 to g++, as GCC 3.3 complains if you do it.
8918 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
8919 everything that WARNING_CFLAGS has, except omit warnings
8920 not suitable for C++.
8921 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
8922 * tests/atlocal.in (CXXFLAGS): New var.
8923 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
8925 Fix a GLR parser bug I reported in February; see
8926 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
8927 The problem was that GLR parsers did not conform to the C standard,
8928 because actions like { $1 = $2 + $3; } expanded to expressions
8929 that invoked YYFILL in separate subexpressions, and YYFILL assigned
8930 to a local variable. The C standard says that expressions
8931 like (var = f ()) + (var = f ()) have undefined behavior.
8932 Another problem was that GCC sometimes issues warnings that
8933 yyfill and its parameters are unused.
8935 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
8937 (yyfill): New function.
8939 (yyuserAction): Change type of yynormal to bool, so that it matches
8940 the new yyfill signature. Mark it as possibly unused.
8943 Follow up on a bug I reported in February, where a Bison-generated
8944 parser can loop. Provide a test case and a fix for yacc.c. I
8945 don't have a fix for lalr1.cc or for glr.c, unfortunately.
8946 The original bug report is in:
8947 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
8949 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
8950 macro's size was becoming unwieldy.
8951 (yyerrlab): Do not discard an empty lookahead symbol, as this
8952 might destroy garbage.
8953 (yyerrorlab): New label, with the old contents of YYERROR,
8954 plus the following change: pop the stack of rhs corresponding
8955 to the production that invoked YYERROR. That is how Yacc
8956 behaves, and POSIX requires this behavior.
8957 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
8958 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
8959 Define 'alarm' to do nothing if unistd.h is not available.
8960 Add a new rule "exp: '-' error;" to test the above change to
8961 data/yacc.c. Use 'alarm' to abort any test taking longer than
8962 10 seconds, as it's probably looping.
8963 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
8964 Also, the new yacc.c generates two fewer diagnostics for an
8967 2003-05-24 Paul Eggert <eggert@twinsun.com>
8969 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
8970 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
8971 This fixes a problem reported by John Bowman when the Compaq/HP
8972 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
8974 * data/yacc.c (union yyalloc): Likewise.
8975 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
8977 Switch from 'int' to 'bool' where that makes sense.

9060 parse-param arguments.
9061 (yy::b4_parser_class_name): Declare instance variables to
9062 hold parse-param arguments.
9063 * tests/calc.at: s/value/semantic_value/ because value clashes
9064 with a member of yy::b4_parser_class_name. Adjust C++ code
9065 to handle %parse-param. Enable %parse-param test in C++.
9067 2003-05-12 Paul Eggert <eggert@twinsun.com>
9069 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
9070 English a bit. Fix fclose typo. Change "const char" to "char
9071 const", and use ANSI C rather than K&R for "main". Suggest
9072 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
9073 and suggest yy_switch_to_buffer.
9075 2003-05-05 Paul Eggert <eggert@twinsun.com>
9077 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
9078 C89. This avoids a diagnostic on compilers that define __STDC__
9079 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
9080 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9082 2003-05-03 Paul Eggert <eggert@twinsun.com>
9084 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
9085 Do not overrun array bounds.
9086 This should fix a bug reported today by Olatunji Oluwabukunmi in
9087 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
9089 2003-04-29 Akim Demaille <akim@epita.fr>
9091 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
9092 * src/getargs.c, src/getargs.h: here, as bool, not int.
9093 (nondeterministic_parser): New.
9094 * src/parse-gram.y, src/scan-gram.l: Support
9095 %nondeterministic-parser.
9096 * src/output.c (prepare): Use nondeterministic_parser instead
9097 of glr_parser where appropriate.
9098 * src/tables.c (conflict_row, action_row, save_row)
9099 (token_actions, token_actions, pack_vector): Ditto.
9101 2003-04-29 Akim Demaille <akim@epita.fr>
9103 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
9105 2003-04-29 Akim Demaille <akim@epita.fr>
9107 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
9108 with %pure-parser and %locations to exercise the patch from Yakov
9111 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
9113 * data/yacc.c: (b4_lex_param): Corrected for the case where
9114 %lex-param is provided and %pure-parser isn't.
9116 2003-04-27 Paul Eggert <eggert@twinsun.com>
9118 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
9119 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
9120 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
9121 if it is not defined.
9122 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
9124 2003-04-26 Paul Eggert <eggert@twinsun.com>
9126 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
9127 Declare to be of type suitable for the ninf value itself, not of
9128 type suitable for the corresponding table, since the latter might
9129 be unsigned but the ninf value might be negative. This fixes a
9130 bug reported by Alexandre Duret-Lutz in
9131 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
9133 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
9134 invokes it. We shouldn't invoke it twice because it will attempt
9135 to put error.o in the archive twice. This fixes a glitch reported
9136 by Martin Mokrejs in
9137 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9139 2003-04-21 Paul Eggert <eggert@twinsun.com>
9141 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
9144 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
9146 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
9147 Fix obvious typo that results in uncompilable GLR parsers
9148 when both %pure-parser and %locations are used. (trivial change)
9150 2003-04-17 Paul Eggert <eggert@twinsun.com>
9152 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
9153 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
9154 Do not insert the expected token via unput, as this runs afoul
9155 of a POSIX-compatibility bug in flex 2.5.31.
9156 All uses changed to BEGIN the parent state,
9157 since we no longer insert the expected token via unput.
9158 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
9159 that is no longer emitted after the above change.
9161 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
9162 the first one. This change is from Paul Hilfinger, and it fixes
9163 regression reported by Werner Lemberg in
9164 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
9166 (resolve_sr_conflict): Don't invoke state_errs_set
9167 unless one or more tokens have been explicitly made errors.
9168 Otherwise, the above change causes Bison to abort.
9170 * tests/existing.at (GNU pic Grammar): New test case, taken from
9173 2003-03-31 Akim Demaille <akim@epita.fr>
9175 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
9177 2003-03-31 Akim Demaille <akim@epita.fr>
9179 * src/output.c (prepare_symbols): Avoid trailing spaces in the
9182 2003-03-31 Akim Demaille <akim@epita.fr>
9184 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
9185 From Paul Hilfinger.
9187 2003-03-29 Akim Demaille <akim@epita.fr>
9189 * m4/error.m4: Do not put under dynamic conditions some code which
9190 expansion is under static control.
9192 2003-03-29 Akim Demaille <akim@epita.fr>
9194 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
9196 2003-03-29 Akim Demaille <akim@epita.fr>
9198 * doc/bison.texinfo (Strings are Destroyed): New.
9200 2003-03-13 Paul Eggert <eggert@twinsun.com>
9202 * .cvsignore: Add configure.lineno.
9203 * src/.cvsignore: Add yacc.
9204 * tests/.cvsignore: Add testsuite.log.
9205 * doc/fdl.texi: Sync with latest FSF version.
9207 2003-03-12 Paul Eggert <eggert@twinsun.com>
9209 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
9210 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
9211 cursor, instead of leaving it undefined. This fixes a bug
9212 reported by Tim Van Holder in
9213 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
9214 * tests/input.at (Torturing the Scanner): Test the scanner on
9215 an empty input file, which was Tim Van Holder's test case.
9217 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
9218 <sys/resource.h> can be included, include sys/time.h and
9219 sys/times.h first, if available. This works around the SunOS
9220 4.1.4 porting bug reported by Bruce Becker in
9221 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
9223 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
9224 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
9227 Merge changes from gnulib. This was prompted because the CVS
9228 snapshot didn't build on Solaris 7 due to strnlen problems.
9230 These changes need to be merged back into gnulib:
9231 * lib/hash.c: Include <stdbool.h> unconditionally.
9232 * m4/onceonly.m4 (m4_quote): New macro.
9233 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
9234 Quote AC_FOREACH variable-expansions properly.
9235 The 2003-01-03 obstack.h change also needs merging.
9236 {end of changes requiring merging}
9238 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
9239 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
9240 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
9241 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
9242 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
9243 New files, imported from gnulib.
9244 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
9247 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
9248 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
9251 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
9253 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
9254 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
9255 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
9256 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
9257 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
9258 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
9259 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
9260 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
9261 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
9262 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
9263 (jm_PREREQ_ARGMATCH): Remove.
9264 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
9265 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
9267 * src/system.h: Include <stdbool.h> unconditionally.
9269 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
9270 assuming at least C89 in the bitset code for some time now.
9272 2003-03-03 Akim Demaille <akim@epita.fr>
9276 2003-03-02 Akim Demaille <akim@epita.fr>
9278 * doc/bison.texinfo (Table of Symbols): Reactivate the
9279 documentation for %lex-param, and %parse-param.
9281 2003-03-02 Akim Demaille <akim@epita.fr>
9283 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
9284 generate verbose error messages.
9285 Use the number of tokens as an upper bound in yytname, as it
9286 cannot be a non terminal.
9288 2003-03-02 Akim Demaille <akim@epita.fr>
9290 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
9293 2003-03-02 Akim Demaille <akim@epita.fr>
9295 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
9296 Use them to exercise yycheck overrun.
9297 Based on Andrew Suffield's grammar.
9299 2003-03-02 Akim Demaille <akim@epita.fr>
9301 Create tests/local.at for Bison generic testing macros.
9303 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
9304 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
9306 * tests/calc.at (AT_CHECK_CALC): Adjust.
9307 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
9308 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
9309 * tests/local.at: here.
9310 (AT_COMPILE_CXX): Tags the tests using it as c++.
9311 Ignore the test if CXX is not functional.
9313 2003-03-01 Paul Eggert <eggert@twinsun.com>
9315 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
9316 not loc->end, since loc->end might contain garbage and this leads
9317 to undefined behavior on some platforms.
9318 (id_loc, token_start): Use (IF_LINTed) initial values that do not
9319 depend on *loc, so that the reader doesn't give the the false
9320 impression that *loc is initialized.
9321 (<INITIAL>"%%"): Do not bother setting code_start, since its value
9322 does not survive the return.
9324 2003-03-01 Akim Demaille <akim@epita.fr>
9326 * src/scan-gram.l (code_start): Always initialize it when entering
9327 into yylex, as SC_EPILOGUE is activated *before* the corresponding
9328 yylex invocation. An alternative would be making it static, but
9329 then it starts with the second %%'s beginning, instead of its end.
9331 2003-02-28 Paul Eggert <eggert@twinsun.com>
9333 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
9334 around a UnixWare 7.1.1 porting bug reported by John Hughes in
9335 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
9337 2003-02-26 Paul Eggert <eggert@twinsun.com>
9339 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
9340 Remove Sequent/Pyramid discussion (nobody uses them any more).
9341 Merge VMS and MS-DOS discussion; these ports may well be dead
9342 but let's keep mentioning them for now. Put <> around email
9343 addresses. Add copyright notice.
9345 2003-02-24 Paul Eggert <eggert@twinsun.com>
9347 * data/glr.c (yy_reduce_print): yylineno -> yylno,
9348 to avoid collision with flex use of yylineno.
9349 Problem reported by Bruce Lilly in
9350 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

9359 change integer types.
9360 Suggested by Paul Eggert.
9362 2003-02-21 Akim Demaille <akim@epita.fr>
9364 * doc/bison.texinfo: Use "location" consistently to refer to @n,
9365 to avoid confusions with lalr1.cc's notion of Position.
9366 Suggested by Paul Eggert.
9368 2003-02-20 Akim Demaille <akim@epita.fr>
9370 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
9371 before initial_columns.
9372 (location.hh): Use consistent variable names when defining the
9374 Use "last" so that we subtract from Positions, not from unsigned.
9376 2003-02-20 Akim Demaille <akim@epita.fr>
9378 * data/lalr1.cc (position.hh): New subfile, including the extended
9379 and Doxygen'ed documentation of class Position.
9380 (location.hh): Use it.
9381 Document a` la Doxygen.
9382 With the help of Benoit Perrot.
9384 2003-02-20 Akim Demaille <akim@epita.fr>
9386 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
9388 Redefine AT_YYERROR_SEES_LOC_IF using it.
9389 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
9391 Don't use the location in yy::Parser::error_ and
9392 yy::Parser::print_ when not %locations.
9393 Activate more lalr1.cc tests.
9395 2003-02-19 Akim Demaille <akim@epita.fr>
9397 * data/lalr1.cc: When displaying a line number, be sure to make it
9400 2003-02-19 Akim Demaille <akim@epita.fr>
9402 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
9404 (YYABORT, YYACCEPT, YYERROR): New.
9405 * tests/calc.at: Renable the lalr1.cc test.
9407 2003-02-19 Akim Demaille <akim@epita.fr>
9409 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
9410 error recovery, mixing with/without pops and discarding of the
9413 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
9415 2003-02-17 Paul Eggert <eggert@twinsun.com>
9417 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
9418 * tests/testsuite.at (AT_COMPILE): Use them.
9419 This fixes the testsuite problem reported by Robert Lentz in
9420 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
9422 2003-02-12 Paul Eggert <eggert@twinsun.com>
9424 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
9425 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in

9427 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
9428 Check for malloc failure, for consistency with yacc.c.
9429 (yytname_size): Remove, for consistency with yacc.c.
9431 The bug still remains in data/lalr1.cc, as I didn't have time
9434 2003-02-06 Akim Demaille <akim@epita.fr>
9436 * configure.ac (GXX): Rename as...
9437 (CXX): this, to keep the original Autoconf semantics.
9439 * data/lalr1.cc: Fix b4_copyright invocations.
9440 If YYDEBUG is not defined, don't depend upon name_ being defined.

9451 * tests/testsuite.at (AT_COMPILE_CXX): New.
9452 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
9453 locations in a more synthetic way.
9454 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
9456 Adjust the C locations to match those from Emacs: first column is
9458 Change all the expected results.
9459 Conform to the GCS: simplify the locations when applicable.
9460 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
9461 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
9462 these CPP macros with the m4 macros new defined by...

9530 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
9531 param to have same name as that of enum, so that we don't use
9532 "s" to stand for a non-state.
9534 2003-02-02 Akim Demaille <akim@epita.fr>
9536 * src/scan-skel.l: Scan more than one inert character per yylex
9539 2003-02-01 Paul Eggert <eggert@twinsun.com>
9543 * po/LINGUAS: Add ms.
9545 2003-01-30 Akim Demaille <akim@epita.fr>
9547 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
9549 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9551 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
9554 Changes in response to error report by S. Eken: GLR mode does not
9555 handle negative $ indices or $ indices in embedded rules correctly.
9556 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
9558 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
9559 (b4_rhs_location): Ditto.
9560 (yyfill): New function to copy from stack tree into array
9562 (yyuserAction): Modify to allow incremental move of semantic values
9563 to rhs array when in GLR mode.
9564 Define YYFILL to use in user-defined actions to fill semantic array
9566 Remove dummy use of yystack, as there is now a guaranteed use.
9567 (yydoAction): Modify to allow incremental move of semantic values
9568 to rhs array when in GLR mode.
9569 (yyresolveAction): Ditto.
9570 (yyglrShiftDefer): Update comment.
9571 (yyresolveStates): Use X == NULL for pointers, not !X.
9572 (yyglrReduce): Ditto.
9575 * tests/glr-regr1.at: Rename to ...
9576 * tests/glr-regression.at: Add new regression test for the problems
9577 described above (adapted from S. Eken).
9578 Update copyright notice.
9579 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
9580 * tests/Makefile.am: Ditto.
9582 2003-01-28 Paul Eggert <eggert@twinsun.com>
9584 * data/lalr1.cc: Do not use @output_header_name@ unless
9585 b4_defines_flag is set. This fixes two bugs reported by
9587 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
9588 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
9590 2003-01-21 Paul Eggert <eggert@twinsun.com>
9592 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
9593 we don't need to worry about yyerrlab1 being reported as an
9594 "unused label" by non-GCC C compilers. The downside is that if
9595 locations are used then a couple of statements are duplicated each
9596 time YYERROR is invoked, but the upside is that the warnings
9598 (yyerrlab1): Move code to YERROR.
9599 (yyerrlab2): Remove. Change uses back to yyerrlab1.
9600 This reverts some of the 2002-12-27 change.
9602 2003-01-17 Paul Eggert <eggert@twinsun.com>
9604 * src/output.c (symbol_printers_output): Fix typo that led
9605 to core dump. Problem reported by Antonio Rus in
9606 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
9608 2003-01-13 Akim Demaille <akim@epita.fr>,
9609 Quoc Peyrot <chojin@lrde.epita.fr>,
9610 Robert Anisko <anisko_r@lrde.epita.fr>
9612 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
9613 when the stacks contain one element, as the loop would otherwise
9614 free the last state, and then use the top state (the one we just
9615 popped). This means that the initial elements will not be freed
9616 explicitly, as is the case in yacc.c; it is not a problem, as
9617 these elements have fake values.
9619 2003-01-11 Paul Eggert <eggert@twinsun.com>
9621 * NEWS: %expect-violations are now just warnings, reverting
9622 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
9623 bootstrapping problem reported by Matthias Klose; see
9624 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
9625 * src/conflicts.c (conflicts_print): Likewise.
9626 * tests/conflicts.at (%expect not enough, %expect too much,
9627 %expect with reduce conflicts): Likewise.
9628 * doc/bison.texinfo (Expect Decl): Document this. Also mention
9629 that the warning is enabled if the number of conflicts changes
9630 (not necessarily increases).
9632 * src/getargs.c (version): Update copyright year.
9634 2003-01-09 Akim Demaille <akim@epita.fr>
9636 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
9638 2003-01-08 Paul Eggert <eggert@twinsun.com>
9640 * Makefile.maint (WGETFLAGS):
9641 New macro, containing "-C off" to disable proxy caches.
9642 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
9643 (rel-check): Use $(WGET) instead of wget.
9645 2003-01-06 Paul Eggert <eggert@twinsun.com>
9647 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
9648 the GLR paper of Scott, Johnstone and Hussain.
9650 2003-01-04 Paul Eggert <eggert@twinsun.com>
9652 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
9653 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
9654 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
9655 (EXTRA_LIBRARIES): New var, for liby.a.
9656 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
9657 (EXTRA_SCRIPTS): New var, for yacc.
9659 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
9660 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
9661 Problem reported by Nelson H. F. Beebe.
9663 2003-01-03 Paul Eggert <eggert@twinsun.com>
9665 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
9666 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
9667 when compiling Bison 1.875's `bitset bset = obstack_alloc
9668 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
9670 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
9671 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
9672 grow to a huge size with typical invocation.
9674 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
9675 Use the pattern recommended by Autoconf 2.57, except also protect
9676 against double-definition.
9677 * src/system.h: Likewise.
9678 Portability issues reported by Nelson H. F. Beebe.
9680 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
9681 All uses changed. Provide a definition in both C and C++.
9682 (yytrue, yyfalse): Define even if defined (__cplusplus).
9684 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
9685 Reported by Nelson H. F. Beebe.
9687 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
9689 2003-01-02 Paul Eggert <eggert@twinsun.com>
9691 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
9692 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
9693 Bug reported by Nelson H. F. Beebe.
9695 2003-01-01 Paul Eggert <eggert@twinsun.com>
9699 2002-12-30 Paul Eggert <eggert@twinsun.com>
9701 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
9703 (<INITIAL>","): Here. This causes stray "," to be treated
9706 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
9707 last brace in braced code when not in Yacc mode, for compatibility
9708 with Bison 1.35. This resurrects the 2001-12-15 patch to
9711 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
9712 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
9714 2002-12-28 Paul Eggert <eggert@twinsun.com>
9716 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
9717 that of SYM's type. This fixes Debian bug 168069, reported by
9720 2002-12-28 Paul Eggert <eggert@twinsun.com>
9724 Switch back to the Yacc style of conflict reports, undoing some
9725 of the 2002-07-30 change.
9726 * doc/bison.texinfo (Understanding): Use Yacc style for
9727 conflict reports. Also, use new way of locating rules.
9728 * src/conflicts.c (conflict_report):
9729 Renamed from conflict_report_yacc, removing the old
9730 'conflict_report'. Translate the entire conflict report at once,
9731 so that we don't assume that "," has the same interpretation in
9733 (conflicts_output): Use Yacc-style conflict report for each state,
9734 instead of our more-complicated style.
9735 (conflicts_print): Use Yacc-style conflict report, except print
9736 the input file name when not emulating Yacc.
9737 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
9738 Conflicted Reduction, %expect not enough, %expect too much,
9739 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
9740 * tests/existing.at (GNU Cim Grammar): Likewise.
9741 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
9743 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
9744 fatal): Don't invoke fflush; it's not needed and it might even be
9745 harmful for stdout, as stdout might not be open.
9746 * src/reduce.c (reduce_print): Likewise.
9748 2002-12-27 Paul Eggert <eggert@twinsun.com>
9750 Fix a bug where error locations were not being recorded correctly.
9751 This problem was originally reported by Paul Hilfinger in
9752 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
9754 * data/yacc.c (yyparse): New local var yylerrsp, to record the
9755 top of the location stack's error locations.
9756 (yyerrlab): Set it. When discarding a token, push its location
9757 onto yylerrsp so that we don't lose track of the error's end.
9758 (yyerrlab1): Now is only the target of YYERROR, so that we can
9759 properly record the location of the action that failed. For GCC
9760 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
9761 GCC warning about yyerrlab1 being unused if YYERROR is unused.
9762 (yyerrlab2): New label, which yyerrlab now falls through to.
9763 Compute the error's location by applying YYLLOC_DEFAULT to
9764 the locations of all the symbols that went into the error.
9765 * doc/bison.texinfo (Location Default Action): Mention that
9766 YYLLOC_DEFAULT is also invoked for syntax errors.
9767 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9768 Error locations include the locations of all the tokens that were
9769 discarded, not just the last token.
9771 2002-12-26 Paul Eggert <eggert@twinsun.com>
9773 * src/files.c: Include quote.h.
9774 (compute_output_file_names): Warn if we detect conflicting
9775 outputs to the same file. This should catch the misunderstanding
9776 exemplified by Debian Bug 165349, reported by Bruce Stephens..
9778 * src/conflicts.c (conflicts_print): If the user specifies
9779 "%expect N", report an error if there are any reduce/reduce
9780 conflicts. This is what the manual says should happen.
9781 This fixes Debian bug 130890, reported by Anthony DeRobertis.
9782 * tests/conflicts.at (%expect with reduce conflicts): New test.
9784 Don't use m4_include on relative file names, as it doesn't work as
9785 desired if there happens to be a file with that name under ".".
9787 * m4sugar/version.m4: Remove; it was included but it wasn't used.
9788 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
9789 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
9790 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
9791 * src/output.c (output_skeleton): Use full path names when
9792 specifying a file to include; don't rely on include path, as
9793 it's unreliable when the working file contains a file with
9796 2002-12-25 Paul Eggert <eggert@twinsun.com>
9798 Remove obsolete references to bison.simple and bison.hairy.
9799 Problem mentioned by Aubin Mahe in
9800 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
9801 * data/glr.c: Comment fix.
9802 * doc/bison.1: Remove references. Also, mention "yacc".
9804 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
9807 * src/parse-gram.y (declaration): Use enum "report_states" rather
9808 than its numeric value 1.
9810 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
9811 opening a new one. This fixes Debian bug 165349, reported by
9814 2002-12-24 Paul Eggert <eggert@twinsun.com>
9818 * Makefile.maint (cvs-update): Don't assume that the shell
9819 supports $(...), as Solaris sh doesn't.
9821 * src/parse-gram.y (lloc_default): Remove test for empty
9822 nonterminals at the end, since it didn't change the result.
9824 2002-12-24 Paul Eggert <eggert@twinsun.com>
9826 If the user does not define YYSTYPE as a macro, Bison now declares it
9827 using typedef instead of defining it as a macro. POSIX requires this.
9828 For consistency, YYLTYPE is also declared instead of defined.
9830 %union directives can now have a tag before the `{', e.g., the
9831 directive `%union foo {...}' now generates the C code
9832 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
9833 The default union tag is `YYSTYPE', for compatibility with Solaris 9
9834 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
9835 instead of `yyltype'.
9837 `yystype' and `yyltype' are now obsolescent macros instead of being
9838 typedefs or tags; they are no longer documented and will be
9839 withdrawn in a future release.
9841 * data/glr.c (b4_location_type): Remove.
9842 (YYSTYPE): Renamed from yystype.
9843 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
9844 (struct YYLTYPE): Renamed from struct yyltype.
9845 (YYLTYPE): Renamed from yyltype.
9846 (yyltype, yystype): New (and obsolescent) macros,
9847 for backward compatibility.
9848 * data/yacc.c: Likewise.
9850 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
9851 does not specify a union tag. This is for compatibility with
9854 * src/parse-gram.y (add_param): 2nd arg is now char * not char
9855 const *, since it is now modified by stripping surrounding { }.
9856 (current_braced_code): Remove.
9857 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
9858 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
9859 trailing " {...}". Now of type <chars>.
9860 (grammar_declaration): Adjust to bundled tokens.
9861 (code_content): Remove; stripping is now done by add_param.
9862 (print_token_value): Print contents of bundled tokens.
9863 (token_name): New function.
9865 * src/reader.h (braced_code, current_braced_code): Remove.
9866 (token_name): New decl.
9868 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
9869 token_type, not braced_code code_kind. All uses changed.
9870 (SC_PRE_CODE): New state, for scanning after a keyword that
9871 has (or usually has) an immediately-following braced code.
9872 (token_type): New local var, to keep track of which token type
9873 to return when scanning braced code.
9874 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
9875 <INITIAL>"%parse-param", <INITIAL>"%printer",
9876 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
9877 instead of returning a token type immediately.
9878 (<INITIAL>"{"): Set token type.
9879 (<SC_BRACED_CODE>"}"): Use it.
9880 (handle_action_dollar, handle_action_at): Now returns bool
9881 indicating success. Fail if ! current_rule; this prevents a core dump.
9882 (handle_symbol_code_dollar, handle_symbol_code_at):
9883 Remove; merge body into caller.
9884 (handle_dollar, handle_at): Complain in invalid contexts.
9886 * NEWS, doc/bison.texinfo: Document the above.
9887 * NEWS: Fix years and program names in copyright notice.
9889 2002-12-17 Paul Eggert <eggert@twinsun.com>
9891 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
9892 Reporting, Table of Symbols): Omit mentions of %lex-param and
9893 %parse-param from the documentation for now.
9895 2002-12-15 Paul Eggert <eggert@twinsun.com>
9897 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
9898 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
9899 lookahead symbol, and which sets yychar in parser actions) and it
9900 disagreed with the Bison documentation. Bug
9901 reported by Andrew Walrond.
9903 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
9904 as the caller now does that.
9905 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
9906 (YYEMPTY): Parenthesize right hand side, since others use it.
9907 (yyparse): Don't assume that our generated code is the only code
9910 2002-12-13 Paul Eggert <eggert@twinsun.com>
9914 POSIX requires a "yacc" command.
9915 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
9916 (MOSTLYCLEANFILES): Add yacc.
9918 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
9919 as an alias for bison y.
9921 * po/LINGUAS: Add da.
9923 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
9924 problem with latest <getopt.h>.
9925 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
9927 * doc/fdl.texi: Upgrade to 1.2.
9928 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
9929 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
9930 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
9932 * config/install-sh: Sync with autotools.
9934 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
9935 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
9936 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
9937 locations are requested.
9938 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
9939 locations are requested.
9941 2002-12-12 Paul Eggert <eggert@twinsun.com>
9943 Remove unportable casts and storage allocation tricks.
9944 While we're at it, remove almost all casts, since they
9945 usually aren't needed and are a sign of trouble.
9947 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
9949 * src/derives.c (derives_compute): Do not subtract NTOKENS from
9950 the pointer DSET returned by malloc; this isn't portable.
9951 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
9952 Similarly for DERIVES.
9953 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
9954 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
9955 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
9957 * src/derives.c (derives_compute): Do not bother invoking
9958 int_of_rule_number, since rule numbers are integers.
9960 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
9961 rather than XMALLOC (char, N).
9963 * src/files.c (filename_split): Rewrite to avoid cast.
9965 * src/gram.h (symbol_number_as_item_number,
9966 item_number_as_symbol_number, rule_number_as_item_number,
9967 item_number_as_rule_number):
9968 Now inline functions rather than macros, to avoid casts.
9969 * src/state.h (state_number_as_int): Likewise.
9970 * src/tables.c (state_number_to_vector_number,
9971 symbol_number_to_vector_number): Likewise.
9973 * src/gram.h (int_of_rule_number): Remove; no longer used.
9975 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
9976 since the resulting storage is always stored into.
9978 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
9981 * src/muscle_tab.c (muscle_m4_output):
9982 Now inline. Return bool, not int.
9983 * src/state.c (state_compare): Likewise.
9984 * src/symtab.c (symbol_check_defined,
9985 symbol_check_alias_consistency, symbol_pack, symbol_translation,
9986 hash_compare_symbol, hash_symbol):
9988 * src/uniqstr.c (uniqstr_print): Likewise.
9989 * src/muscle_tab.c (muscle_m4_output_processor):
9990 New function, to avoid casts.
9991 * src/state.c (state_comparator, stage_hasher): Likewise.
9992 * src/symtab.c (symbol_check_defined_processor,
9993 symbol_check_alias_consistency_processor, symbol_pack_processor,
9994 symbol_translation_processor, hash_symbol_comparator,
9995 hash_symbol_hasher): Likewise.
9996 * src/uniqstr.c (uniqstr_print_processor): Likewise.
9997 * src/muscle_tab.c (muscles_m4_output):
9998 Use new functions instead of casting old functions unportably.
9999 * src/state.c (state_hash_new): Likewise.
10000 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
10001 symbols_token_translations_init):
10003 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
10005 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
10006 var instead of casting to long, to avoid casts.
10007 (prepare_states): Use MALLOC rather than alloca, so that we don't
10008 have to worry about alloca.
10009 * src/state.c (state_hash_lookup): Likewise.
10011 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
10012 local var instead of casting to unsigned char, to avoid casts.
10014 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
10015 STATE_ALLOC): Remove.
10016 (transitions_new, errs_new, reductions_new, state_new): Use malloc
10017 rather than calloc, and use offsetof to avoid allocating slightly
10019 (state_new): Initialize all members.
10021 * src/state.c (state_hash): Use unsigned accumulator, not signed.
10023 * src/symtab.c (symbol_free): Remove; unused.

10029 (symbol_processor): Remove.
10030 (symbols_do): Remove decl; now static.

10034 (<inttypes.>, <stdint.h>): Include if available.
10035 (uintptr_t): New type, if system lacks it.
10036 (CALLOC, MALLOC, REALLOC): New macros.
10037 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
10040 * src/tables.c (table_size): Now int, to pacify GCC.
10041 (table_grow, table_ninf_remap): Use signed table size.

10053 2002-12-09 Paul Eggert <eggert@twinsun.com>
10055 Change identifier spellings to avoid collisions with names
10056 that are reserved by POSIX.
10058 Don't use names ending in _t, since POSIX reserves them.
10059 For consistency, remove _e and _s endings -- they're weren't
10060 needed to remove ambiguity. All uses changed.
10061 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
10062 turn was just renamed from struniq_t.
10063 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
10064 which in turn was just renamed from struniq_processor_t.
10065 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

10136 value_t_as_yystype -> value_as_yystype.
10138 Don't include <errno.h> in the mainstream code, since it
10139 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
10140 * lib/get-errno.c, lib/get-errno.h: New files.
10141 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
10143 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

10151 (TAB_EXT): Renamed from EXT_TAB.
10152 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
10154 Avoid str[a-z]*, since <string.h> reserves that name space.
10155 Change all instances of "struniq" in names to "uniqstr", and
10156 likewise for "STRUNIQ" and "UNIQSTR".
10157 * src/uniqstr.c: Renamed from src/struniq.c.
10158 * src/uniqstr.h: Renamed from src/struniq.h.
10159 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
10160 * src/files.c (strsuffix): Remove; unused.

10169 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
10170 (N_EXPAND): Renamed from N_STRETCH.

10174 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

10181 (BASE_MINIMUM): Renamed from BASE_MIN.
10182 (ACTION_MAX): Remove; unused.
10183 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
10184 Unnecessary casts removed from above defines.
10187 Fix misspelling in names.
10188 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
10189 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
10193 * lib/timevar.c (timevar_report): Renamed from time_report,
10194 for consistency with other names.
10195 * lib/timevar.h (timevar_report): New decl.
10196 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
10199 Sort include-file uses.
10201 Reorder all include files under src to be in the order "system.h".
10202 then the ../lib include files in angle brackets (alphabetized),
10203 then the . include files in double-quotes (alphabetized). Fix
10204 dependency breakages encountered in this process, as follows:
10205 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
10206 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
10207 * src/state.h: Include "symtab.h".
10209 2002-12-08 Paul Eggert <eggert@twinsun.com>
10211 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
10212 since this causes problems when __file__ contains character
10213 sequences like "@" that are treated specially by src/scan-skel.l.
10214 Instead, just use the file's basename. This fixes the bug
10215 reported by Martin Mokrejs in
10216 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
10218 2002-12-06 Paul Eggert <eggert@twinsun.com>
10220 Add support for rules that do not have trailing semicolons, as
10221 POSIX requires. Improve the quality of locations in Bison
10224 * src/location.c: Include <quotearg.h>.
10225 (empty_location): Now const.
10226 (location_print): New function. Follow the recommendation of the
10227 GNU Coding Standards for locations that span file boundaries.
10228 * src/location.h: Do not include <quotearg.h>; no longer needed.
10229 (boundary): New type.
10230 (location_t): Use it. This allows locations to span file boundaries.
10231 All member uses changed: file -> start.file or end.file (as needed),
10232 first_line -> start.line, first_column -> start.column,
10233 last_line -> end.line, last_column -> end.column.
10234 (equal_boundaries): New function.
10235 (LOCATION_RESET, LOCATION_STEP): Remove.
10236 (LOCATION_PRINT): Remove. All callers changed to use location_print.
10237 (empty_location): Now const.
10238 (location_print): New decl.
10239 * src/parse-gram.y (lloc_default): New function, which handles
10240 empty locations more accurately.
10241 (YYLLOC_DEFAULT): Use it.
10242 (%token COLON): Remove.
10243 (%token ID_COLON): New token.
10245 (declarations, rules): Remove trailing semicolon.
10246 (declaration, rules_or_grammar_declaration):
10247 Allow empty (";") declaration.
10248 (symbol_def): Remove empty actions; no longer needed.
10249 (rules_or_grammar_declaration): Remove trailing semicolon.
10250 (semi_colon.opt): Remove.
10251 * src/reader.h: Include location.h.
10252 (scanner_cursor): New decl.
10253 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
10255 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
10257 (STEP): Remove. No longer needed, now that adjust_location does
10258 the work. All uses removed.
10259 (scanner_cursor): New var.
10260 (adjust_location): Renamed from extend_location. It now sets
10261 *loc and adjusts the scanner cursor. All uses changed.
10262 Don't bother testing for CR.
10263 (handle_syncline): Remove location arg; now updates scanner cursor.
10264 All callers changed.
10265 (unexpected_end_of_file): Now accepts start boundary of token or
10266 comment, not location. All callers changed. Update scanner cursor,
10268 (SC_AFTER_IDENTIFIER): New state.
10269 (context_state): Renamed from c_context. All uses changed.
10270 (id_loc, code_start, token_start): New local vars.
10271 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
10272 processing of Yacc white space and equivalents here.
10273 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
10274 instead of returning ID immediately, since we need to search for
10275 a subsequent colon.
10276 (<INITIAL>"'", "\""): Save token_start.
10277 (<INITIAL>"%{", "{", "%%"): Save code_start.
10278 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
10279 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
10280 BEGIN context_state at end, not INITIAL.
10281 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
10282 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
10283 Return correct token start.
10284 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
10285 the start of a character, string or multiline comment is found.
10286 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
10287 Reduction): Adjust reported locations to match the more-precise
10288 results now expected.
10289 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
10290 * tests/reduce.at (Useless Rules, Reduced Automaton,
10291 Underivable Rules): Likewise.
10292 * tests/regression.at (Invalid inputs): No longer `expecting ";"
10293 or "|"' now that so many other tokens are allowed by the new grammar.
10295 * src/complain.h (current_file): Remove duplicate decl;
10296 current_file is now owned by files.h.
10297 * src/complain.c, src/scan-gram.l: Include files.h.
10299 2002-12-06 Paul Eggert <eggert@twinsun.com>
10301 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
10302 promotes to int; it might be unsigned int.
10303 * data/yacc.c (yy_reduce_print): Likewise.
10305 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
10306 be #defined in the prologue, not in the Bison declarations.
10307 This fixes Debian Bug 102878, reported by Shaul Karl.
10309 2002-12-02 Paul Eggert <eggert@twinsun.com>
10311 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
10312 * lib/strtoul.c: New file, from gnulib.
10313 This fixes a porting bug reported by Peter Klein in
10314 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
10316 2002-11-30 Paul Eggert <eggert@twinsun.com>
10318 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
10319 and put only a forward declaration in the prologue. This is for
10320 consistency with the other scanner helper functions.
10322 Type clashes now generate warnings, not errors, since it
10323 appears that POSIX may allow some grammars with type clashes.
10324 * src/reader.c (grammar_current_rule_check): Warn about
10325 type clashes instead of complaining.
10326 * tests/input.at (Type Clashes): Expect warnings, not complaints.
10328 Add Yacc library, since POSIX requires it.
10329 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
10330 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
10331 * lib/main.c, lib/yyerror.c: New files.
10333 gram_error can be static; it need not be extern.
10334 * src/reader.h (gram_error): Remove decl.
10335 * src/parse-gram.y (gram_error): Now static. Add static decl.
10336 (print_token_value): Omit parameter names from forward decl,
10339 2002-11-29 Paul Eggert <eggert@twinsun.com>
10341 * doc/bison.texinfo: Emphasize that yylex and yyerror must
10342 be declared before being used. E.g., one should typically
10343 declare them in the prologue. Use GNU coding style in examples.
10344 Put "const" consistently after the type it modifies. Mention
10345 that C99 supports "inline". Mention that yyerror traditionally
10348 %parse-param and %lex-param now take just one argument, the
10349 declaration; the argument name is deduced from the declaration.
10351 * doc/bison.texinfo (Parser Function, Pure Calling, Error
10352 Reporting, Table of Symbols): Document this.
10353 * src/parse-gram.y (add_param): New function.
10355 (declaration): Implement new rule for %parse-param and %lex-param.
10356 * src/scan-gram.l: "," now elicits a warning, rather than being
10357 a token; this is more compatible with byacc.
10358 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
10360 2002-11-27 Paul Eggert <eggert@twinsun.com>
10362 Rename identifiers to avoid real and potential collisions.
10364 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
10365 to avoid collision with lex macro described by Bruce Lilly in
10366 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10367 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10368 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
10369 * src/parse-gram.y (print_token_value): Renamed from yyprint.
10371 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
10372 The name "yycontrol" violates the name space rules, and this stuff
10373 wasn't being used anyway.
10374 (input): Remove action; this stuff wasn't being used.
10375 (gram_error): Rename local variable yylloc -> loc.
10376 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
10377 (YY_DECL): Don't use "yy" at start of local variables.
10378 All uses changed, e.g., yylloc -> loc.
10379 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
10380 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
10381 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
10382 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
10384 * src/parse-gram.y (gram_error): loc is now const *.
10385 * src/reader.h (gram_error): Likewise.
10387 2002-11-24 Paul Eggert <eggert@twinsun.com>
10391 * tests/actions.at (Actions after errors): Use an output format
10392 more similar to that of the Printers and Destructors test.
10393 Test the position of the ';' token too.
10394 (Printers and Destructors): Likewise.
10395 (Printers and Destructors: %glr-parser): Remove for now, to avoid
10396 unnecessarily alarming people when the test fails.
10398 * data/yacc.c (yyerrlab1): Move this label down, so that the
10399 parser does not discard the lookahead token if the user code
10400 invokes YYERROR. This change is required for POSIX conformance.
10402 * lib/error.c: Sync with gnulib.
10404 2002-11-22 Paul Eggert <eggert@twinsun.com>
10406 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
10407 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
10408 * lib/xmalloc.c: Likewise.
10410 2002-11-20 Paul Eggert <eggert@twinsun.com>
10412 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
10414 2002-11-20 Paul Eggert <eggert@twinsun.com>
10416 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
10417 should use `if (! x) abort ();' rather than `assert (x);', and
10418 anyway it's one less thing to worry about configuring.
10420 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
10421 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
10422 and replace all instances of assert with abort.
10423 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
10424 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
10426 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
10427 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
10428 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
10429 hash_find_entry, hash_rehash, hash_insert): Likewise.

10452 * src/tables.c (tables_generate): Likewise.
10454 * src/struniq.c (struniq_assert): Now returns void, and aborts
10455 if the assertion is false.

10457 * src/struniq.h: Likewise.
10459 2002-11-18 Paul Eggert <eggert@twinsun.com>
10461 * data/glr.c (yygetLRActions): Replace `yyindex' with
10462 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
10463 This fixes the regression with Sun ONE Studio 7 cc that I reported in
10464 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
10466 2002-11-18 Akim Demaille <akim@epita.fr>
10468 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
10470 From Tim Van Holder.
10472 2002-11-17 Paul Eggert <eggert@twinsun.com>
10474 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
10475 to "SyntaxError" for consistency with my 2002-11-15 change.
10477 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
10478 not define to {}, since this breaks the common use of `YYDPRINTF
10479 ((...));' if a single statement is desired (e.g. before `else').
10480 Work around GCC warnings by surrounding corresponding calls with
10482 (yyhasResolvedValue): Remove unused function.
10483 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
10485 (yyreportSyntaxError): Renamed from yyreportParseError.
10486 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
10488 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
10489 extern when possible. Remove unused initializations.
10491 2002-11-16 Akim Demaille <akim@epita.fr>
10493 Augment the similarity between GLR and LALR traces.
10495 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
10496 (YY_REDUCE_PRINT): New.
10497 (yyparse): Use them.
10498 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
10500 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
10501 state reached after the reduction/recovery, since...
10502 (yyparse, yyprocessOneStack): Report the state we are entering in.
10504 2002-11-16 Akim Demaille <akim@epita.fr>
10506 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
10507 Add support for --trace=skeleton.
10508 * src/scan-skel.l: %option debug.
10509 Scan strings of non-@ or \n instead of character by character.
10510 (scan_skel): Handle trace_skeleton.
10512 (@output_parser_name@, @output_header_name@): ``Restore'' their
10513 support (used to be M4 macros).
10514 * data/yacc.c: Quote larger chunks, a la glr.c.
10515 * data/lalr1.cc: Likewise.
10516 The header guards are no longer available, so use some other
10517 string than `YYLSP_NEEDED'.
10519 2002-11-16 Akim Demaille <akim@epita.fr>
10521 Make the ``Printers and Destructors'' test more verbose, taking
10522 `yacc.c''s behavior as (possibly wrong) reference.
10524 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
10525 instead of fprint on stdout.
10526 Set and report the last_line of the symbols.
10527 Consistently display values and locations.
10529 2002-11-16 Paul Eggert <eggert@twinsun.com>
10531 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
10533 2002-11-15 Paul Eggert <eggert@twinsun.com>
10535 * tests/actions.at (Actions after errors): New test case.
10537 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
10538 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
10539 tests/action.at, tests/calc.at, tests/conflicts.at,
10540 tests/cxx-type.at, tests/regression.at:
10541 "parse error" -> "syntax error" for POSIX compatibility.
10542 "parsing stack overflow..." -> "parser stack overflow" so
10543 that code matches Bison documentation.
10545 2002-11-15 Akim Demaille <akim@epita.fr>
10547 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
10548 take two BRACED_CODE, not two string_content.
10549 Free the scanner's obstack when we are done.
10550 (code_content): New.
10551 * tests/calc.at: Adjust.
10552 * doc/bison.texinfo: Adjust.
10553 Also, make sure to include the `,' for these declarations.
10555 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
10557 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
10558 definition; avoids potential autoreconf problems.
10560 2002-11-15 Akim Demaille <akim@epita.fr>
10562 Always check the value returned by yyparse.
10564 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
10565 returned by yyparse.
10566 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
10568 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
10569 returned by yyparse.
10571 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>

10576 2002-11-14 Paul Eggert <eggert@twinsun.com>
10578 * src/output.c (output_skeleton): Call xfopen instead of
10579 duplicating xfopen's body.
10581 Fix bugs reported by Nelson H. F. Beebe in
10582 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
10584 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
10585 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
10586 Group compiler. Instead, use "$CC -E bar.c". Include the .h
10587 file twice in the grammar, as an extra check.
10589 * tests/input.at (Torturing the Scanner): Surround the
10590 backslash-newline tests with "#if 0", to make it less likely that
10591 we'll run into compiler bugs. Bring back solitary \ inside
10592 comment, but add a closing comment to work around HP C bug. Don't
10593 test backslash-newline in C character constant.
10595 2002-11-14 Akim Demaille <akim@epita.fr>
10597 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
10598 status of the compiler.
10599 Calling `exit 1' is no longer needed.
10600 Reported by Nelson H. F. Beebe.
10602 2002-11-14 Akim Demaille <akim@epita.fr>
10604 * tests/atlocal.in (CPPFLAGS): We have config.h.
10605 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
10607 * tests/actions.at, tests/calc.at, tests/conflicts.at,
10608 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
10609 * tests/regression.at, tests/torture.at: Use them for all the
10610 grammars that are to be compiled.
10611 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
10612 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
10613 * doc/bison.texinfo (GLR Parsers): Document `inline'.
10615 2002-11-14 Akim Demaille <akim@epita.fr>
10617 * doc/bison.texinfo: Various formatting changes (alignments in
10618 samples, additional @group/@end group, GCS in samples.
10619 Use @deffn instead of simple @table to define the directives,
10620 macros, variables etc.
10622 2002-11-13 Paul Eggert <eggert@twinsun.com>
10624 Fix some bugs reported by Albert Chin-A-Young in
10625 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
10627 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
10628 -o c"; the HP C compiler chatters during compilation.
10629 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
10630 * tests/headers.at (export YYLTYPE): Likewise.
10632 * tests/input.at (Torturing the Scanner): Remove lines containing
10633 solitary backslashes, as they tickle a bug in the HP C compiler.
10635 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
10636 comments, since they're not portable. Use GNU coding style.
10638 2002-11-13 Akim Demaille <akim@epita.fr>
10640 * data/yacc.c: Leave bigger chunks of quoted text.
10641 (YYDSYMPRINTF): New.
10642 Use it to report symbol activities.
10643 * data/glr.c (YYDSYMPRINTF): New.

10650 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
10651 (yyglrReduce): Return yyok, not 0.
10652 This should avoid the enumerated-type warnings reported
10653 by Nelson H. F. Beebe in
10654 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
10656 * lib/bbitset.h (BITSET_INLINE): Remove.
10657 * lib/bitset.h [! BITSET_INLINE]: Remove.
10658 (bitset_set, bitset_reset, bitset_test): Rename local vars
10659 to avoid shadowing warnings by GCC.
10661 * data/glr.c (inline): Remove #define. It's the user's
10662 responsibility to #define it away, just like 'const'.
10663 This fixes one of the bugs reported by Nelson H. F. Beebe in
10664 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
10666 * Makefile.maint (po-check): Scan .l and .y files instead of the
10667 .c and the .h files that they generate. This fixes the bug
10668 reported by Tim Van Holder in:
10669 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
10670 Look for N_ as well as for _. Try to avoid matching #define for
10672 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
10673 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
10674 * src/scan-gram.l: Revamp regular expressions so that " and '
10675 do not confuse xgettext.
10677 * src/struniq.h (struniq_new): Do not declare the return type
10678 to be 'const'; this violates the C standard.
10679 * src/struniq.c (struniq_new): Likewise.
10681 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
10683 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
10684 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
10687 2002-11-12 Akim Demaille <akim@epita.fr>
10689 * Makefile.maint: Sync with Autoconf:
10690 (local_updates): New.
10692 2002-11-12 Akim Demaille <akim@epita.fr>

10696 2002-11-12 Akim Demaille <akim@epita.fr>

10706 2002-11-12 Akim Demaille <akim@epita.fr>
10708 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
10709 Use it to test the GLR parser.
10711 2002-11-12 Akim Demaille <akim@epita.fr>
10713 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
10715 * data/glr.c (yystos): New.
10716 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
10717 (YYDSYMPRINT): New.
10718 (yyval): Don't define it, it is handled via M4.
10719 (yyrecoverParseError): Free verbosely the discarded symbols.
10720 * data/yacc.c (yysymprint): Remove, rather...
10721 (b4_yysymprint_generate): invoke.
10722 * data/c.m4 (b4_yysymprint_generate): New.
10723 Accept pointers as arguments, as opposed to the version from
10725 (b4_yydestruct_generate): Likewise.
10726 * tests/cations.at (Printers and Destructors): Use Bison directives
10727 instead of CPP macros.
10728 Don't rely on internal details.
10730 2002-11-12 Akim Demaille <akim@epita.fr>
10732 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
10733 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
10734 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
10735 it against YYEMPTY and so forth), work on yytoken (i.e., set
10736 it to YYEMPTY etc.).
10737 (yydestruct): Replace with a b4_yydestruct_generate invocation.
10738 (b4_symbol_actions): Remove.
10739 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
10740 for 0, end-of-input.
10742 2002-11-12 Akim Demaille <akim@epita.fr>
10744 * doc/bison.texinfo (Destructor Decl): New.
10746 2002-11-12 Akim Demaille <akim@epita.fr>
10748 * src/tables.c (tables_generate): Use free for pointers that
10749 cannot be NULL, not XFREE.
10750 (pack_vector): Use assert, not fatal, for bound violations.
10751 * src/state.c (state_new): Likewise.
10752 * src/reader.c (reader): Likewise.
10753 * src/lalr.c (set_goto_map): Likewise.
10754 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
10757 2002-11-12 Akim Demaille <akim@epita.fr>
10759 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
10761 * src/scan-gram.l (last_string): Is global to the file, not to
10763 * src/parse-gram.y (input): Don't append the epilogue here,
10764 (epilogue.opt): do it here, and free the scanner's obstack.
10765 * src/reader.c (epilogue_set): Rename as...
10766 (epilogue_augment): this.
10767 * data/c.m4 (b4_epilogue): Defaults to empty.

10825 2002-11-11 Paul Eggert <eggert@twinsun.com>
10827 Revamp to fix many (but not all) of the C- and M4-related quoting
10828 problems. Among other things, this fixes the Bison bug reported
10829 by Jan Hubicka when processing the Bash grammar; see:
10830 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
10832 Use new @ escapes consistently. Represent brackets with @{ and @}
10833 rather than @<:@ and @:>@, since this works a bit better with dumb
10834 editors like vi. Represent @ with @@, since @ is now consistently
10835 an escape. Use @oline@ and @ofile@ rather than __oline__ and
10836 __ofile__, to avoid unexpected expansions. Similarly, use @output
10837 rather than #output.
10839 * data/c.m4 (b4_copyright): Omit file name from comment, since
10840 the file name could contain "*/".
10841 (b4_synclines_flag): Don't quote the 2nd argument; it should already
10842 be quoted. All uses changed.
10844 * data/glr.c: Use new @ escapes consistently.
10845 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
10846 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
10847 Remove, since they couldn't handle arbitrary characters in file
10849 * data/lalr1.cc: Likewise.
10850 * data/yacc.c: Likewise.
10852 * src/files.c (output_infix): Remove; all uses removed.
10853 * src/files.h: Likewise.
10855 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
10856 mishandled funny characters in file names, and anyway it isn't
10858 * data/yacc.c: Likewise.
10859 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
10861 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
10862 * data/yacc.c: Likewise.
10864 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
10866 (muscle_init): Quote filename as a C string.
10867 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
10868 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
10869 * src/output.c (escaped_file_name_output): New function.
10870 (prepare_symbols): Quote tokens for M4.
10871 (prepare): Don't insert output_infix, output_prefix,
10872 output_parser_name, output_header_name; this is now down by scan-skel.
10873 Insert skeleton as a C string.
10875 * src/output.c (user_actions_output, symbol_destructors_output,
10876 symbol_printers_output): Quote filenames for C and M4.
10877 * src/reader.c (prologue_augment, epilogue_set): Likewise.
10879 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
10880 escapes other than \\ and \'; this simplifies the code.
10881 (<SC_STRING>): Likewise, for \\ and \".
10882 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
10883 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
10884 Use new escapes @{ and @} for [ and ].
10886 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
10887 them with auto vars.
10888 Switch to new escape scheme, where @ is the escape character uniformly.
10889 Abort if a stray escape character is found. Avoid unbounded input
10890 buffer when parsing non-escaped text.
10892 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
10893 __oline__, #output, $@, and @{ do not have unintended meanings.
10895 2002-11-09 Paul Eggert <eggert@twinsun.com>
10897 Fix the test failure due to GCC warnings described in
10898 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
10899 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
10900 evaluate to 0 if it's impossible for NINF to be in the respective
10902 (yygetLRActions, yyrecoverParseError): Use them.
10904 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
10905 counted in the token inserted at end of file. Now takes
10906 location_t *, not location_t, so that the location can be
10907 adjusted. All uses changed.
10909 * tests/regression.at (Invalid inputs): Adjust wording in
10910 diagnostic to match the new behavior.
10912 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
10913 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
10914 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
10915 abort ();'. This reduces the runtime of the "Many lookaheads"
10916 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
10919 2002-11-07 Paul Eggert <eggert@twinsun.com>
10921 * src/parse-gram.y (CHARACTER): Remove unused token.
10924 * src/scan-gram.l: Remove stack option. We no longer use the
10925 stack, since the stack was never deeper than 1; instead, use the
10926 new auto var c_context to record the stacked value.
10928 Remove nounput option. At an unexpected end of file, we now unput
10929 the minimal input necessary to end cleanly; this simplifies the
10932 Avoid unbounded token sizes where this is easy.
10934 (unexpected_end_of_file): New function.
10935 Use it to systematize the error message on unexpected EOF.
10936 (last-string): Now auto, not static.

10939 (percent_percent_count): Move decl to just before use.
10940 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
10941 not the (never otherwised-used) CHARACTER.
10943 2002-11-07 Akim Demaille <akim@epita.fr>
10945 Let yyerror always receive the msg as last argument, so that
10946 yyerror can be variadic.
10948 * data/yacc.c (b4_yyerror_args): New.
10949 Use it when calling yyerror.
10950 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

10963 * src/output.c (symbol_printers_output)
10964 (symbol_destructors_output): Quote the file name.

10979 * src/output.c (user_actions_output): Likewise.
10980 (prepare): Define 'b4_synclines_flag'.
10981 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
10983 2002-11-06 Akim Demaille <akim@epita.fr>

10993 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10995 * src/tables.c (matching_state): Don't allow states to match if
10996 either has GLR conflict entries.
10998 2002-11-05 Paul Eggert <eggert@twinsun.com>
11000 * src/scan-gram.l: Use more accurate diagnostics, e.g.
11001 "integer out of range" rather than "invalid value".
11002 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
11005 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
11006 Also, remove one static variable in the scanner.
11008 * src/scan-gram.l (braces_level): Now auto, not static.
11009 Initialize to zero if the compiler is being picky.
11010 (INITIAL): Clear braces_level instead of incrementing it.
11011 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
11012 as POSIX 1003.1-2001 requires.
11013 * src/system.h (IF_LINT): New macro, taken from coreutils.
11014 * configure.ac: Define "lint" if --enable-gcc-warnings.
11016 2002-11-05 Akim Demaille <akim@epita.fr>
11018 * src/scan-gram.l: When it starts with `%', complain about the
11019 whole directive, not just that `invalid character: %'.
11021 2002-11-04 Akim Demaille <akim@epita.fr>
11023 * Makefile.maint: Update from Autoconf.
11024 (update, cvs-update, po-update, do-po-update): New.
11026 2002-11-04 Akim Demaille <akim@epita.fr>
11028 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
11030 Have yyerror `use' its arguments.
11031 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
11032 returns true when location & yacc & pure & parse-param.
11033 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
11035 2002-11-04 Akim Demaille <akim@epita.fr>
11037 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
11039 * src/scan-gram.l: Use [\'] instead of ['] to pacify
11042 Use quote, not quote_n since LOCATION_PRINT no longer uses the
11045 2002-11-03 Paul Eggert <eggert@twinsun.com>
11047 * src/reader.c (get_merge_function, grammar_current_rule_check):
11048 Use consistent diagnostics for reporting type name clashes.
11049 Quote the types with <>, for consistency with Yacc.
11050 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
11052 2002-11-03 Akim Demaille <akim@epita.fr>
11054 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
11056 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
11057 (b4_parse_param): Remove.
11058 Use b4_identification.
11059 Propagate b4_pure_args where needed to pass them to yyerror.
11060 * data/glr.m4 (b4_parse_param): Remove.
11061 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

11063 Use b4_identification.
11064 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
11065 b4_user_formals and b4_user_args.
11066 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
11067 (yyreportAmbiguity): When using a pure parser, also need
11068 the location, and the parse-params.
11070 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
11071 When using a pure parser, also need the parse-params.
11073 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
11074 (%pure-parser + %parse-param) LALR and GLR parsers.
11075 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
11076 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
11077 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
11078 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

11081 * doc/bison.texinfo: Untabify the whole file.
11082 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
11083 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
11084 (Error Reporting): Adjust to these new directives.
11085 Document %error-verbose, deprecate YYERROR_VERBOSE.
11087 2002-11-03 Akim Demaille <akim@epita.fr>
11089 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
11090 AT_CHECK_CALC_GLR invocations to use % directives, instead of
11091 command line options.
11092 * tests/cxx-type.at: Formatting changes.
11094 2002-11-03 Paul Eggert <eggert@twinsun.com>
11096 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
11097 to count columns correctly, and to check for invalid inputs.
11099 Use mbsnwidth to count columns correctly. Account for tabs, too.
11100 Include mbswidth.h.
11101 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
11102 (extend_location): New function.
11103 (YY_LINES): Remove.
11105 Handle CRLF in C code rather than in Lex code.

11112 Handle backslash-newline correctly in C code.
11113 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
11114 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
11116 (tag, splice): New EREs. Do not allow NUL or newline in tags.
11117 Use {splice} wherever C allows backslash-newline.
11118 YY_STEP after space, newline, vertical-tab.
11119 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
11121 (letter, id): Don't assume ASCII; e.g., spell out a-z.
11123 ({int}, handle_action_dollar, handle_action_at): Check for integer
11126 (YY_STEP): Omit trailing semicolon, so that it's more like C.
11128 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
11129 as well as \000. Check for UCHAR_MAX, not 255.
11130 Allow \x with an arbitrary positive number of digits, as in C.
11131 Check for overflow here.
11132 Allow \? and UCNs, for compatibility with C.
11134 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
11135 with quote slot used by complain_at.
11137 * tests/input.at: Add tests for backslash-newline, m4 quotes
11138 in symbols, long literals, and funny escapes in strings.
11140 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
11141 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
11142 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
11143 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
11144 * m4/mbswidth.m4: New file, from GNU coreutils.
11146 * doc/bison.texinfo (Grammar Outline): Document // comments.
11147 (Symbols): Document that trigraphs have no special meaning in Bison,
11148 nor is backslash-newline allowed.
11149 (Actions): Document that trigraphs have no special meaning.

11154 2002-11-02 Paul Eggert <eggert@twinsun.com>
11156 * src/reader.c: Don't include quote.h; not needed.
11157 (get_merge_function): Reword warning to be consistent with
11158 type clash diagnostic in grammar_current_rule_check.
11160 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
11161 bug in trigraph handling.
11163 * src/output.c (prepare_symbols): When printing token names,
11164 escape "[" as "@<:@" and likewise for "]".
11166 * src/system.h (errno): Remove declaration, as we are now
11167 assuming C89 or better, and C89 guarantees errno.
11169 2002-10-30 Paul Eggert <eggert@twinsun.com>
11171 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
11172 Check for close failures.
11173 * src/files.h (xfclose): Return void, not int, since it always
11175 * src/files.c (xfclose): Likewise. Report I/O error if ferror
11177 * src/output.c (output_skeleton): Use xfclose rather than fclose
11178 and ferror. xfclose now checks ferror.
11180 * data/glr.c (YYLEFTMOST_STATE): Remove.
11181 (yyreportTree): Use a stack-based leftmost state. This avoids
11182 our continuing battles with bogus warnings about initializers.
11184 2002-10-30 Akim Demaille <akim@epita.fr>
11186 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

11191 * tests/glr-regr1.at: New test for reported regressions.
11192 * tests/testsuite.at: Add glr-regr1.at test.

11199 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
11200 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
11201 we use malloc. Don't assume 'A' through 'Z' are contiguous.
11202 Don't assume strdup exists; POSIX says its an XSI extension.
11203 Check for buffer overflow on input.
11205 2002-10-24 Akim Demaille <akim@epita.fr>
11207 * src/output.c (output_skeleton): Don't disable M4sugar comments
11208 too soon: it results in comments being expanded.
11209 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
11212 2002-10-24 Akim Demaille <akim@epita.fr>
11214 * data/yacc.c (m4_int_type): New.
11215 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
11216 char' as only yacc.c wants K&R portability.
11217 * data/glr.c (yysigned_char): Remove.
11218 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
11219 Reported by Quoc Peyrot.
11221 2002-10-23 Paul Eggert <eggert@twinsun.com>
11223 * src/main.c (main): With --trace=time, report times even if a
11224 non-fatal error occurs. Formerly, the times were reported in some
11225 such cases but not in others.
11226 * src/reader.c (reader): Just return if a complaint has been issued,
11227 instead of exiting, so that 'main' can report times.
11229 2002-10-22 Akim Demaille <akim@epita.fr>
11231 * src/system.h: Include sys/types.
11232 Reported by Bert Deknuydt.
11234 2002-10-23 Paul Eggert <eggert@twinsun.com>
11236 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
11237 Suggested by Art Haas.
11239 2002-10-22 Paul Eggert <eggert@twinsun.com>
11241 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
11242 decl; not needed any more.
11243 * src/main.c (main): Use return to exit, undoing yesterday's change.
11244 The last OS that we could find where this wouldn't work is
11245 SunOS 3.5, and that's too old to worry about now.
11247 * data/glr.c (struct yyltype): Define members even when not
11248 doing locations. This is more consistent with yacc.c, and it
11249 works around the following bug reports:
11250 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
11251 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
11253 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
11254 @acronym consistently. Standardize on "Yacc" instead of "YACC",
11255 "Algol" instead of "ALGOL". Give a bit more history about BNF.
11257 2002-10-22 Akim Demaille <akim@epita.fr>
11259 * data/README: New.
11261 2002-10-21 Paul Eggert <eggert@twinsun.com>
11263 Be consistent about 'bool'; the old code used an enum in one
11264 module and an int in another, and this violates the C standard.
11265 * m4/stdbool.m4: New file, from coreutils 4.5.3.
11266 * configure.ac (AC_HEADER_STDBOOL): Add.
11267 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
11268 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
11269 * src/symtab.c (hash_compare_symbol_t): Likewise.
11270 * src/system.h (bool, false, true): Use a definition consistent
11271 with ../lib/hash.c. All uses changed.
11273 * src/complain.c (warning_issued): Renamed from warn_message_count,
11274 so that we needn't worry about integer overflow (!).
11275 Now of type bool. All uses changed.
11276 (complaint_issued): Renamed from complain_message_count; likewise.
11278 * src/main.c (main): Use exit to exit with failure.
11280 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
11281 rather than 1 and 0.
11282 * src/main.c (main): Likewise.
11283 * src/getargs.c (getargs): Likewise.
11284 * src/reader.c (reader): Likewise.
11286 * src/getarg.c (getargs): Remove duplicate code for
11287 "Try `bison --help'".
11289 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
11290 What was that "2" for?
11292 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
11293 * src/getargs.c (usage): Likewise.
11295 * src/getargs.c (getargs): When there are too few operands, report
11296 the last one. When there are too many, report the first extra
11297 one. This is how diffutils does it.
11299 2002-10-20 Paul Eggert <eggert@twinsun.com>
11301 Remove K&R vestiges.
11302 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
11303 * src/complain.c (VA_START): Remove. Assume prototypes.
11304 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
11305 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
11306 fatal): Assume prototypes.
11307 * src/complain.h: Assume prototypes.
11308 * src/system.h (PARAMS): Remove.
11309 Include <limits.h> unconditionally, since it's guaranteeed even
11310 for a freestanding C89 compiler.
11311 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
11312 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
11314 2002-10-20 Akim Demaille <akim@epita.fr>
11316 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
11317 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.

11320 (yyprocessOneStack): Use them.
11321 (yy_reduce_print): New.
11322 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
11324 2002-10-20 Akim Demaille <akim@epita.fr>
11326 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
11327 arguments and output `void'.
11328 (b4_c_function): Rename as...
11329 (b4_c_function_def): this.
11330 (b4_c_function_decl, b4_c_ansi_function_def)
11331 (b4_c_ansi_function_decl): New.
11332 Change the interpretation of the arguments: before `int, foo', now
11334 * data/yacc.c (yyparse): Prototype and define thanks to these.
11335 Adjust b4_c_function_def uses.
11336 * data/glr.c (yyparse): Likewise, but ANSI only.
11338 2002-10-20 Akim Demaille <akim@epita.fr>
11340 * src/output.c (prepare): Move the definition of `tokens_number',
11341 `nterms_number', `undef_token_number', `user_token_number_max'
11343 (prepare_tokens): Here.
11344 (prepare_tokens): Rename as...
11345 (prepare_symbols): this.
11346 (prepare): Move the definition of `rules_number' to...
11347 (prepare_rules): here.
11348 (prepare): Move the definition of `last', `final_state_number',
11349 `states_number' to...
11350 (prepare_states): here.
11351 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
11353 2002-10-20 Akim Demaille <akim@epita.fr>
11355 * src/tables.h, src/tables.c, src/output.c: Comment changes.
11357 2002-10-20 Akim Demaille <akim@epita.fr>
11359 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
11362 2002-10-20 Akim Demaille <akim@epita.fr>
11364 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
11365 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
11367 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
11369 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
11370 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
11373 2002-10-19 Paul Eggert <eggert@twinsun.com>
11375 Do not create a temporary file, as that involves security and
11376 cleanup headaches. Instead, use a pair of pipes.
11377 Derived from a suggestion by Florian Krohm.
11378 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
11379 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
11380 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
11381 (BISON_PREREQ_SUBPIPE): Add.
11382 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
11383 Add subpipe.h, subpipe.c.
11384 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
11385 * po/POTFILES.in: Add lib/subpipe.c.
11386 * src/output.c: Include "subpipe.h".
11387 (m4_invoke): Remove decl.
11388 (scan_skel): New decl.
11389 (output_skeleton): Use pipe rather than temporary file for m4 input.
11390 Check that m4sugar.m4 is readable, to avoid deadlock.
11391 Check for pipe I/O error.
11392 * src/scan-skel.l (readpipe): Remove decl.
11393 (scan_skel): New function, to be used in place of m4_invoke.
11394 Read from stream rather than file.
11396 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
11397 float, as this generates a warning on Solaris 8 + GCC 3.2 with
11398 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
11399 this generates a more-accurate value anyway.
11401 * lib/timevar.c (timervar_accumulate): Rename locals to
11402 avoid confusion with similarly-named more-global.
11403 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
11405 * src/output.c (prepare): Use xstrdup to convert char const *
11406 to char *, to avoid GCC warning.
11408 2002-10-19 Akim Demaille <akim@epita.fr>
11410 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
11411 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
11412 Use them to have `calc.y' ready for %pure-parser.
11413 * data/yacc.c (YYLEX): Pass a yylex return type to
11414 b4_c_function_call.
11416 2002-10-19 Akim Demaille <akim@epita.fr>
11418 Prototype support of %lex-param and %parse-param.
11420 * src/parse-gram.y: Add the definition of the %lex-param and
11421 %parse-param tokens, plus their rules.
11422 Drop the `_' version of %glr-parser.
11424 * src/scan-gram.l (INITIAL): Scan them.
11425 * src/muscle_tab.c: Comment changes.
11426 (muscle_insert, muscle_find): Rename `pair' as `probe'.
11427 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
11428 (muscle_entry_s): The `value' member is no longer const.
11429 Adjust all dependencies.
11430 * src/muscle_tab.c (muscle_init): Adjust: use
11431 MUSCLE_INSERT_STRING.
11432 Initialize the obstack earlier.
11433 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
11434 (muscle_pair_list_grow): New.
11435 * data/c.m4 (b4_c_function_call, b4_c_args): New.
11436 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
11437 * tests/calc.at: Use %locations, not --locations.
11438 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
11440 2002-10-19 Akim Demaille <akim@epita.fr>
11442 * src/getargs.c (usage): Take status as argument and exit
11444 Report the traditional `Try ... --help' message when status != 0.
11445 (usage, version): Don't take a FILE * as arg, it is pointless.
11446 (getargs): When there is an incorrect number of arguments, make it
11447 an error, and report it GNUlically thanks to `usage ()'.
11449 2002-10-18 Paul Eggert <eggert@twinsun.com>
11451 * data/glr.c (yyreportParseError): Don't assume that sprintf
11452 yields the length of the printed string, as this is not true
11453 on SunOS 4.1.4. Reported by Peter Klein.
11455 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
11456 * tests/conflicts.at (%nonassoc and eof): Likewise.
11457 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
11459 2002-10-17 Akim Demaille <akim@epita.fr>
11461 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
11462 * src/getargs.c (trace_types, trace_args): Adjust.
11463 * src/reader.c (grammar_current_rule_prec_set)
11464 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
11465 Standardize error messages.
11466 And s/@prec/%prec/!
11467 (reader): Use trace_flag to enable scanner/parser debugging,
11468 instead of an adhoc scheme.
11469 * src/scan-gram.l: Remove trailing debugging code.
11471 2002-10-16 Paul Eggert <eggert@twinsun.com>
11473 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
11476 * NEWS: Officially drop support for building Bison with K&R C,
11477 since it didn't work anyway and it's not worth worrying about.
11478 * Makefile.maint (wget_files): Remove ansi2knr.c.
11479 (ansi2knr.c-url_prefix): Remove.
11480 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
11481 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11482 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11484 2002-10-15 Paul Eggert <eggert@twinsun.com>
11486 Stop using the "enum_" trick for K&R-style function definitions;
11487 it confused me, and I was the author! Instead, assume that people
11488 who want to use K&R C compilers (when using these modules in GCC,
11489 perhaps?) will run ansi2knr.
11491 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
11492 All uses of "enum_" changed to "enum ".
11493 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
11494 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
11496 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

11503 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
11504 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
11505 Use function prototypes; this removes the need for declaring
11506 static functions simply to provide their prototypes.
11507 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

11564 2002-10-14 Akim Demaille <akim@epita.fr>
11566 * tests/Makefile.am (maintainer-check-posix): New.
11568 2002-10-14 Akim Demaille <akim@epita.fr>
11570 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
11573 2002-10-14 Akim Demaille <akim@epita.fr>
11575 * src/tables.c (table_ninf_remap): base -> tab.
11576 Reported by Matt Rosing.
11578 2002-10-14 Paul Eggert <eggert@twinsun.com>
11580 * tests/action.at, tests/calc.at, tests/conflicts.at,
11581 tests/cxx-type.at, tests/headers.at, tests/input.at,
11582 tests/regression.at, tests/synclines.at, tests/torture.at:
11583 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
11584 so that the tests still work even if POSIXLY_CORRECT is set.
11585 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
11587 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
11588 for portability to K&R hosts. Fix typo: signed char is guaranteed
11589 only to 127, not to 128.
11590 * data/glr.c (yysigned_char): New type.
11591 * data/yacc.c (yysigned_char): Likewise.
11592 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
11594 2002-10-13 Paul Eggert <eggert@twinsun.com>
11596 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
11597 true due to limited range of data type" warning from GCC.
11599 * data/c.m4 (b4_token_defines): Protect against double-inclusion
11600 by wrapping enum yytokentype's definition inside #ifndef
11601 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
11603 2002-10-13 Akim Demaille <akim@epita.fr>
11605 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
11606 Un yy- yyrhs to avoid the name clash with the global YYRHS.
11608 2002-10-13 Akim Demaille <akim@epita.fr>
11610 * Makefile.maint: Update from Autoconf 2.54.
11611 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
11613 2002-10-13 Akim Demaille <akim@epita.fr>
11615 * src/print.c (print_state): Separate the list of solved conflicts
11616 from the other items.
11617 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
11619 2002-10-13 Akim Demaille <akim@epita.fr>
11621 Let nondeterministic skeletons be usable with deterministic
11624 With the patch, GAWK compiled by GCC without -O2 passes its test
11625 suite using a GLR parser driven by LALR tables. It fails with -O2
11626 because `struct stat' gives two different answers on my machine:
11627 88 (definition of an auto var) and later 96 (memset on this var).
11628 Hence the stack is badly corrumpted. The headers inclusion is to
11629 blame: if I move the awk.h inclusion before GLR's system header
11630 inclusion, the two struct stat have the same size.
11632 * src/tables.c (pack_table): Always create conflict_table.
11633 (token_actions): Always create conflict_list.
11634 * data/glr.c (YYFLAG): Remove, unused.
11636 2002-10-13 Akim Demaille <akim@epita.fr>
11638 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
11640 (VALGRIND, GXX): New.
11641 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
11642 * tests/bison.in: Run $PREBISON a pre-command.
11643 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
11644 (maintainer-check-g++): New.
11645 * Makefile.am (maintainer-check): New.
11647 2002-10-13 Akim Demaille <akim@epita.fr>
11649 * data/glr.c: Formatting changes.
11650 Tweak some trace messages to match yacc.c's.
11652 2002-10-13 Akim Demaille <akim@epita.fr>
11654 GLR parsers sometimes raise parse errors instead of performing the
11656 Reported by Charles-Henry de Boysson.
11658 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
11659 check the length of the traces when %glr.
11660 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
11662 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
11664 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
11665 (yyltype): Remove the yy prefix from the member names.
11666 (yytable): Complete its comment.
11667 (yygetLRActions): Map error action number from YYTABLE from
11669 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
11670 (which was a bug: it should have been YYTABEL_NINF, and yet it was
11671 not satisfying as we could compare an YYACTION computed from
11672 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
11673 only value for error actions.
11674 (yyreportParseError): In verbose parse error messages, don't issue
11675 `error' in the list of expected tokens.
11676 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
11677 next action to perform to match glr.c's decoding.
11678 (yytable): Complete its comment.
11680 2002-10-13 Paul Eggert <eggert@twinsun.com>
11682 Fix problem reported by Henrik Grubbstroem in
11683 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
11684 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
11685 because the Bison parser reads the second action before reducing
11687 * src/scan-gram.l (rule_length): New static var.
11688 Use it to keep track of the rule length in the scanner, since
11689 we can't expect the parser to be in lock-step sync with the scanner.
11690 (handle_action_dollar, handle_action_at): Use this var.
11691 * tests/actions.at (Exotic Dollars): Test for the problem.
11693 2002-10-12 Paul Eggert <eggert@twinsun.com>
11695 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
11696 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
11697 Include <sys/time.h> when checking for clock_t and struct tms.
11698 Use same include order as source.
11699 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
11700 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
11702 * lib/timevar.c: Update copyright date and clarify comments.
11703 (get_time) [IN_GCC]: Keep the GCC version for reference.
11705 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
11706 GCC version as of today, then merge Bison's changes.
11707 Change "GCC" to "Bison" in copyright notice. timevar.def's
11708 author is Akim, so change that too.
11710 * src/reader.c (grammar_current_rule_check):
11711 Don't worry about the default action if $$ is untyped.
11712 Prevents bogus warnings reported by Jim Gifford in
11713 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
11715 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
11716 * data/glr.c, data/lalr1.cc, data/yacc.c:
11717 Output token definitions before the first part of user declarations.
11718 Fixes compatibility problem reported by Jim Gifford for kbd in
11719 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
11721 2002-10-11 Paul Eggert <eggert@twinsun.com>
11723 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
11724 (yyparse): here. This undoes some of the 2002-07-25 change.
11725 Compatibility problem reported by Ralf S. Engelschall with
11726 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

11741 Portability fixes for bitsets; this also avoids several GCC
11744 * lib/abitset.c: Include <stddef.h>, for offsetof.
11745 * lib/lbitset.c: Likewise.
11747 * lib/abitset.c (abitset_bytes): Return a size that is aligned
11748 properly for vectors of objects. Do not assume that adding a
11749 header size to a multiple of a word size yields a value that is
11750 properly aligned for the whole union.
11751 * lib/bitsetv.c (bitsetv_alloc): Likewise.

11791 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
11793 Do not use "struct bitset_struct" to mean different things in
11794 different modules. Not only is this confusing, it violates
11795 the C Standard, which requires that structure types in different
11796 modules must be compatible if one is to be passed to the other.
11797 * lib/bbitset.h (bitset): Now points to a union, not to a struct.

11842 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
11843 the same width as int. This reapplies a hunk of the 2002-08-12 patch
11844 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
11845 which was inadvertently undone by the 2002-09-30 patch.

12221 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
12222 exit status as failure, not just exit status 1. Sun C exits
12223 with status 2 sometimes.

12393 parsers now contain `reduce 0' as default reduction.

12444 token_translations instead of `0'.
12445 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
12447 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
12448 for the time being: %locations ought to provide it to yyerror.

12452 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

14154 Add an invocation exercising the error token.
14155 Add an invocation demonstrating a stupid error message.

14423 was used solely to set the precedence of the last rule...
14425 2002-04-07 Akim Demaille <akim@epita.fr>
14427 * data/bison.c++, data/bison.simple: Don't output the current file
14428 name in #line, to avoid useless diffs between two identical
14429 outputs under different names.

14433 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

14685 * data/bison.c++: Copy the prologue of bison.simple to fetch

14719 2002-02-14 Paul Eggert <eggert@twinsun.com>
14721 Remove the support for C++ namespace cleanliness; it was
14722 causing more problems than it was curing, since it didn't work
14723 properly on some nonstandard C++ compilers. This can wait
14724 for a proper C++ parser.
14726 * NEWS: Document this.
14727 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
14728 of C++, as it's treated like C now.
14729 * src/bison.simple (YYSTD): Remove.
14730 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):

14742 2002-02-13 Andreas Schwab <schwab@suse.de>
14744 * src/output.c (output_rule_data): Don't output NULL, it might
14745 not be defined yet.
14747 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
14749 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
14750 (Copyright notice): Update.
14752 2002-02-11 Akim Demaille <akim@epita.fr>

14755 nonportable headers.
14757 2002-02-08 Robert Anisko <robert@lrde.epita.fr>

14764 * tests/input.at: New.
14766 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14768 * data/bison.c++: Replace some direct m4 expansions by constants. Be
14769 more consistent when naming methods and variables. Put preprocessor
14770 directives around tables only needed for debugging.
14772 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14774 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
14776 (yy::b4_name::parse): Use print_.
14778 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14780 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
14782 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
14784 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
14786 (yy::b4_name::parse): Build verbose error messages, and use error_.

14792 2002-02-06 Robert Anisko <robert@lrde.epita.fr>

14795 not expanded by m4.
14797 2002-02-05 Akim Demaille <akim@epita.fr>
14799 * data/bison.c++: Adjust to the M4 back end.
14800 More is certainly needed.
14802 2002-02-05 Akim Demaille <akim@epita.fr>
14804 Give a try to M4 as a back end.
14806 * lib/readpipe.c: New, from wdiff.
14807 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
14809 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
14810 specific values. Now it is m4 that performs the lookup.
14811 * src/parse-skel.y: Remove.
14812 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
14813 * src/output.c (actions_output, guards_output)
14814 (token_definitions_output): No longer keeps track of the output
14815 line number, hence remove the second argument.
14816 (guards_output): Check against the guard member of a rule, not the
14819 (output_skeleton): Don't look for the skeleton location, let m4 do
14821 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
14823 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
14824 (prepare): Given that for the time being changesyntax is not
14825 usable in M4, rename the muscles using `-' to `_'.
14826 Define `defines_flag', `output_parser_name' and `output_header_name'.
14827 * src/output.h (actions_output, guards_output)
14828 (token_definitions_output): Adjust prototypes.
14829 * src/scan-skel.l: Instead of scanning the skeletons, it now
14830 processes the output of m4: `__oline__' and `#output'.
14831 * data/bison.simple: Adjust to be used by M4(sugar).
14832 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
14834 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
14835 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
14836 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
14837 shamelessly stolen from CVS Autoconf.
14839 2002-02-05 Akim Demaille <akim@epita.fr>
14841 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
14842 * configure.in: Check for the declarations of free and malloc.
14843 * src/muscle_tab.c: Adjust.
14845 2002-02-05 Akim Demaille <akim@epita.fr>
14847 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
14848 which have no values.
14850 2002-02-05 Akim Demaille <akim@epita.fr>
14852 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
14855 2002-01-29 Paul Eggert <eggert@twinsun.com>
14857 * src/bison.simple (YYSIZE_T): Do not define merely because
14858 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
14859 On some platforms, <alloca.h> does not declare YYSTD (size_t).
14861 2002-01-27 Akim Demaille <akim@epita.fr>
14863 Fix `%nonassoc and eof'.
14865 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
14866 which were not properly copied! Replace
14867 memcpy (res->errs, src->errs, src->nerrs);
14869 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
14871 * tests/regression.at (%nonassoc and eof): Adjust to newest
14872 Autotest: `.' is not in the PATH.
14874 2002-01-27 Akim Demaille <akim@epita.fr>
14876 * tests/sets.at (AT_EXTRACT_SETS): New.
14877 (Nullable): Use it.
14880 2002-01-26 Akim Demaille <akim@epita.fr>
14882 * tests/actions.at, tests/calc.at, tests/headers.at,
14883 * tests/torture.at: Adjust to the newest Autotest which no longer
14884 forces `.' in the PATH.
14886 2002-01-25 Akim Demaille <akim@epita.fr>
14888 * tests/regression.at (%nonassoc and eof): New.
14889 Suggested by Robert Anisko.
14891 2002-01-24 Akim Demaille <akim@epita.fr>
14893 Bison dumps core when trying to complain about broken input files.
14894 Reported by Cris van Pelt.
14896 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
14897 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
14899 (Invalid inputs): Strengthen: exercise parse_percent_token.
14901 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
14903 * src/Makefile.am: Add bison.c++.
14904 * src/bison.c++: New skeleton.
14906 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
14910 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
14912 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
14914 2002-01-20 Marc Autret <marc@gnu.org>
14916 * src/files.c (compute_output_file_names): Fix
14918 2002-01-20 Marc Autret <marc@gnu.org>
14920 * tests/output.at: New test.
14921 * src/files.c (compute_base_names): Don't map extensions when
14922 the YACC flag is set, use defaults.
14923 Reported by Evgeny Stambulchik.
14925 2002-01-20 Marc Autret <marc@gnu.org>
14927 * src/system.h: Need to define __attribute__ away for non-GCC
14928 compilers as well (i.e., the vendor C compiler).
14929 Suggested by Albert Chin-A-Young.
14931 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
14933 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
14934 canonical definition.
14935 * src/system.h: Use the canonical definition for PARAMS (avoids
14936 a conflict with the macro from lib/hash.h).
14938 2002-01-11 Akim Demaille <akim@epita.fr>
14940 * configure.in: Use AC_FUNC_STRNLEN.
14941 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
14943 2002-01-09 Akim Demaille <akim@epita.fr>
14945 * src/files.c, src/files.h (output_infix): New.
14946 (tab_extension): Remove.
14947 (compute_base_names): Compute the former, drop the latter.
14948 * src/output.c (prepare): Insert the muscles `output-infix', and
14950 * src/parse-skel.y (string, string.1): New.
14951 (section.header): Use it.
14952 (section.yacc): Remove.
14953 (prefix): Remove too.
14954 * src/scan-skel.l: Adjust.
14955 * src/bison.simple, src/bison.hairy: Adjust.
14957 2002-01-09 Akim Demaille <akim@epita.fr>
14959 * configure.in (WERROR_CFLAGS): Compute it.
14960 * src/Makefile.am (CFLAGS): Pass it.
14961 * tests/atlocal.in (CFLAGS): Idem.
14962 * src/files.c: Fix a few warnings.
14963 (get_extension_index): Remove, unused.
14965 2002-01-08 Akim Demaille <akim@epita.fr>
14967 * src/getargs.c (AS_FILE_NAME): New.
14968 (getargs): Use it to convert DOSish file names.
14969 * src/files.c (base_name): Rename as full_base_name to avoid
14970 clashes with `base_name ()'.
14971 (filename_split): New.
14972 (compute_base_names): N-th rewrite, using filename_split.
14974 2002-01-08 Akim Demaille <akim@epita.fr>
14976 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
14977 New, stolen from the Fileutils 4.1.
14978 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
14979 * configure.in: Check for the presence of memrchr, and of its
14982 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
14984 * lib/hash.h (__P): Added definition for this macro.
14985 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
14986 BUILT_SOURCES, to ensure they are generated first.
14987 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
14988 %error-verbose to allow bootstrapping with bison 1.30x.
14990 2002-01-06 Akim Demaille <akim@epita.fr>
14992 * src/reader.c (parse_braces): Don't fetch the next char, the
14993 convention is to fetch on entry.
14994 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
14995 'switch' without a following semicolon.
14996 * tests/regression.at (braces parsing): New.
14998 2002-01-06 Akim Demaille <akim@epita.fr>
15000 Bison is dead wrong in its RR conflict reports.
15002 * tests/torture.at (GNU Cim Grammar): New.
15003 * src/conflicts.c (count_rr_conflicts): Fix.
15005 2002-01-06 Akim Demaille <akim@epita.fr>
15007 Creating package.m4 from configure.ac causes too many problems.
15009 * tests/Makefile.am (package.m4): Create it by hand,
15010 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
15012 2002-01-06 Akim Demaille <akim@epita.fr>
15014 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
15017 2002-01-04 Paul Eggert <eggert@twinsun.com>
15019 * doc/bison.texinfo (Debugging):
15020 Remove YYSTDERR; it's no longer defined or used.
15021 Also, s/cstdio.h/cstdio/.
15023 2002-01-03 Akim Demaille <akim@epita.fr>
15025 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
15027 2002-01-03 Akim Demaille <akim@epita.fr>
15029 * src/parse-skel.y (process_skeleton): Don't bind the parser's
15030 tracing code to --trace, wait for a better --trace option, with
15033 2002-01-03 Akim Demaille <akim@epita.fr>
15035 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
15036 The ISO C++ standard is extremely clear about it: stderr is
15037 considered a macro, not a regular symbol (see table 94 `Header
15038 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
15039 Therefore std:: does not apply to it. It still does with fprintf.
15040 Also, s/cstdio.h/cstdio/.
15042 2002-01-03 Akim Demaille <akim@epita.fr>
15044 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
15045 for non system headers.
15047 2002-01-02 Akim Demaille <akim@epita.fr>
15049 Equip the skeleton chain with location tracking, runtime trace,
15050 pure parser and scanner.
15052 * src/parse-skel.y: Request a pure parser, locations, and prefix
15054 (%union): Having several members with the same type does not help
15055 type mismatches, simplify.
15056 (YYPRINT, yyprint): New.
15057 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
15058 (skel_error): this.
15060 * src/scan-skel.l: Adjust to these changes.
15061 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
15062 (LOCATION_PRINT, skel_control_t): New.
15064 2001-12-30 Akim Demaille <akim@epita.fr>
15066 * src/parse-skel.y: Get rid of the shift/reduce conflict:
15067 replace `gb' with BLANKS.
15068 * src/scan-skel.l: Adjust.
15070 2001-12-30 Akim Demaille <akim@epita.fr>
15072 * src/system.h: We don't need nor want bcopy.
15073 Throw away MS-DOS crap: we don't need getpid.
15074 * configure.in: We don't need strndup. It was even causing
15075 problems: because Flex includes the headers *before* us,
15076 _GNU_SOURCE is not defined by config.h, and therefore strndup was
15078 * lib/xstrndup.c: New.
15079 * src/scan-skel.l: Use it.
15080 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
15081 * src/parse-skel.y: Use %directives instead of #defines.
15083 2001-12-30 Akim Demaille <akim@epita.fr>
15085 * src/skeleton.h: New.
15086 * src/output.c (output_parser, output_master_parser): Remove, dead
15088 * src/output.h (get_lines_number, actions_output, guards_output)
15089 (token_definitions_output): Prototype them.
15090 * src/parse-skel.y: Add the license notice.
15091 Include output.h and skeleton.h.
15092 (process_skeleton): Returns void, and takes a single parameter.
15093 * src/scan-skel.l: Add the license notice.
15094 Include skeleton.h.
15095 Don't use %option yylineno: it seems that then Flex imagines
15096 REJECT has been used, and therefore it won't reallocate its
15097 buffers (which makes no other sense to me than a bug). It results
15098 in warnings for `unused: yy_flex_realloc'.
15100 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
15102 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15103 (MUSCLE_INSERT_PREFIX): ...to there.
15104 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15105 (MUSCLE_INSERT_PREFIX): Move from here...
15107 * src/bison.hairy: Add a section directive. Put braces around muscle
15108 names. This parser skeleton is still broken, but Bison should not
15109 choke on a bad muscle 'syntax'.
15110 * src/bison.simple: Add a section directive. Put braces around muscle
15113 * src/files.h (strsuffix, stringappend): Add declarations.
15114 (tab_extension): Add declaration.
15115 (short_base_name): Add declaration.
15117 * src/files.c (strsuffix, stringappend): No longer static. These
15118 functions are used in the skeleton parser.
15119 (tab_extension): New.
15120 (compute_base_names): Use the computations done in this function
15121 to guess if the generated parsers should have '.tab' in their
15123 (short_base_name): No longer static.
15125 * src/output.c (output_skeleton): New.
15126 (output): Disable call to output_master_parser, and give a try to
15127 a new skeleton handling system.

15141 %name-prefix is broken.
15143 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
15144 Adjust all dependencies.
15145 * tests/headers.at (export YYLTYPE): Strengthen this test: use
15148 Renaming yylval but not yylloc is not consistent. Now we do.
15150 * src/bison.simple: Prefix yylloc if used.
15151 * doc/bison.texinfo (Decl Summary): Document that.
15153 2001-12-29 Akim Demaille <akim@epita.fr>
15155 * doc/bison.texinfo: Promote `%long-directive' over
15157 Remove all references to fixed-output-files, yacc is enough.
15159 2001-12-29 Akim Demaille <akim@epita.fr>
15161 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
15162 user prologue. These are defaults.
15163 * tests/actions.at (Mid-rule actions): Make sure the user can
15164 define YYDEBUG and YYERROR_VERBOSE.
15166 2001-12-29 Akim Demaille <akim@epita.fr>
15168 * src/output.c (header_output): Don't forget to export YYLTYPE and
15170 * tests/headers.at (export YYLTYPE): New, make sure it does.
15171 * tests/regression.at (%union and --defines, Invalid CPP headers):
15173 * tests/headers.at: here.
15175 2001-12-29 Akim Demaille <akim@epita.fr>
15177 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
15179 2001-12-29 Akim Demaille <akim@epita.fr>
15181 * tests/actions.at (Mid-rule actions): Output on a single line
15182 instead of several.
15184 2001-12-29 Akim Demaille <akim@epita.fr>
15186 * doc/bison.texinfo: Formatting changes.
15188 2001-12-29 Akim Demaille <akim@epita.fr>
15190 Don't store the token defs in a muscle, just be ready to output it
15191 on command. Now possible via `symbols'. Fixes a memory leak.
15193 * src/output.c (token_definitions_output): New.
15194 (output_parser, header_output): Use it.
15195 * src/reader.c (symbols_save): Remove.
15197 2001-12-29 Akim Demaille <akim@epita.fr>
15199 * src/bison.simple: Do not provide a default for YYSTYPE and
15200 YYLTYPE before the user's prologue. Otherwise it's hardly... a
15203 2001-12-29 Akim Demaille <akim@epita.fr>
15205 Mid-rule actions are simply... ignored!
15207 * src/reader.c (readgram): Be sure to attach mid-rule actions to
15208 the empty-rule associated to the dummy symbol, not to the host
15210 * tests/actions.at (Mid-rule actions): New.
15212 2001-12-29 Akim Demaille <akim@epita.fr>
15216 * src/reader.c (reader): Free grammar.
15218 2001-12-29 Akim Demaille <akim@epita.fr>
15222 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
15223 since it allocates it for each state, although only one is needed.
15224 (allocate_storage): Do it here.
15226 2001-12-29 Akim Demaille <akim@epita.fr>
15228 * src/options.h, src/options.c (create_long_option_table): Rename
15230 (long_option_table_new): this, with a clearer prototype.
15231 (percent_table): Remove, unused,
15232 * src/getargs.c (getargs): Adjust.
15234 2001-12-29 Akim Demaille <akim@epita.fr>
15236 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

15240 2001-12-29 Akim Demaille <akim@epita.fr>
15242 * src/lalr.c (build_relations): Rename `states' as `states1'.
15243 Sorry, I don't understand exactly what it is, no better name...
15245 2001-12-29 Akim Demaille <akim@epita.fr>
15247 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
15248 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

15264 * src/gram.c, src/gram.h (sprec, sassoc): Remove.

15276 * src/reader.c (packsymbols): Fill this table.
15278 * src/conflicts.c (resolve_sr_conflict): Adjust.
15279 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
15281 Use symbols[i]->tag instead of tags[i].
15283 2001-12-29 Akim Demaille <akim@epita.fr>
15285 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
15286 In addition, put a comment in there, to replace...
15287 * tests/regression.at (%union and C comments): Remove.
15289 2001-12-29 Akim Demaille <akim@epita.fr>
15291 * tests/regression.at (Web2c Actions): Blindly move the actual
15292 output as expected output. The contents *seem* right to me, but I
15293 can't pretend reading perfectly parser tables... Nonetheless, all
15294 the other tests pass correctly, the table look OK, even though the
15295 presence of `$axiom' is to be noted: AFAICS it is useless (but
15298 2001-12-29 Akim Demaille <akim@epita.fr>
15300 * src/reader.c (readgram): Don't add the rule 0 if there were no
15301 rules read. In other words, add it _after_ having performed
15302 grammar sanity checks.
15303 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
15305 2001-12-29 Akim Demaille <akim@epita.fr>
15307 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
15308 visible, and some states have now a different number.
15310 2001-12-29 Akim Demaille <akim@epita.fr>
15312 * src/reader.c (readgram): Bind the initial rule's lineno to that
15314 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
15315 (Solved SR Conflicts): Adjust rule 0's line number.
15317 2001-12-29 Akim Demaille <akim@epita.fr>
15319 Fix the `GAWK Grammar' failure.
15321 * src/LR0.c (final_state): Initialize to -1 so that we do compute
15322 the reductions of the first state which was mistakenly confused
15323 with the final state because precisely final_state was initialized
15325 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
15326 now noticed by Bison.
15327 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
15328 have a reduction on $default.
15330 2001-12-29 Akim Demaille <akim@epita.fr>
15332 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
15334 * src/closure.c (print_closure): Likewise.
15335 * src/derives.c (print_derives): Likewise.
15336 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
15339 2001-12-29 Akim Demaille <akim@epita.fr>
15341 * src/lalr.c (lookaheads_print): New.
15342 (lalr): Call it when --trace-flag.
15343 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
15346 2001-12-29 Akim Demaille <akim@epita.fr>
15348 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
15349 when walking through ritem, even via rule->rhs.
15350 * src/reduce.c (dump_grammar, useful_production, reduce_output)
15351 (useful_production, useless_nonterminals): Likewise.
15352 (reduce_grammar_tables): Likewise, plus update nritems.
15353 * src/nullable.c (set_nullable): Likewise.
15354 * src/lalr.c (build_relations): Likewise.
15355 * tests/sets.at (Nullable): Adjust.
15356 Fortunately, now, the $axiom is no longer nullable.
15358 2001-12-29 Akim Demaille <akim@epita.fr>
15360 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

15366 * src/nullable.c (set_nullable): Likewise.
15368 2001-12-29 Akim Demaille <akim@epita.fr>
15370 * src/output.c: Comment changes.
15372 2001-12-27 Paul Eggert <eggert@twinsun.com>
15374 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
15375 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
15376 Sparc, as they were causing more porting problems than the
15377 (minor) performance improvement was worth.
15379 Also, catch up with 1.31's YYSTD.
15381 2001-12-27 Akim Demaille <akim@epita.fr>
15383 * src/output.c (output_gram): Rely on nritems, not the
15384 0-sentinel. See below.
15385 Use -1 as separator, not 0.
15386 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
15387 Rely on -1 as separator in yyrhs, instead of 0.
15388 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
15389 twice `Now at end of input', therefore there are two lines less to
15392 2001-12-27 Akim Demaille <akim@epita.fr>
15394 * tests/regression.at (Unresolved SR Conflicts):
15395 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
15398 2001-12-27 Akim Demaille <akim@epita.fr>
15400 * src/LR0.c (new_state): Recognize the final state by the fact it
15401 is reached by eoftoken.
15402 (insert_start_shifting_state, insert_eof_shifting_state)
15403 (insert_accepting_state, augment_automaton): Remove, since now
15404 these states are automatically computed from the initial state.
15405 (generate_states): Adjust.
15406 * src/print.c: When reporting a rule number to the user, substract
15407 1, so that the axiom rule is rule 0, and the first user rule is 1.
15408 * src/reduce.c: Likewise.
15409 * src/print_graph.c (print_core): For the time being, just as for
15410 the report, depend upon --trace-flags to dump the full set of
15412 * src/reader.c (readgram): Once the grammar read, insert the rule
15413 0: `$axiom: START-SYMBOL $'.
15414 * tests/set.at: Adjust: rule 0 is now displayed, and since the
15415 number of the states has changed (the final state is no longer
15416 necessarily the last), catch up.
15418 2001-12-27 Akim Demaille <akim@epita.fr>
15420 Try to make the use of the eoftoken valid. Given that its value
15421 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
15422 is used instead of > 0 where appropriate, (ii), depend upon nritems
15423 instead of the 0-sentinel.
15425 * src/gram.h, src/gram.c (nritems): New.
15426 Expected to be duplication of nitems, but for the time being...
15427 * src/reader.c (packgram): Assert nritems and nitems are equal.
15428 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
15429 * src/closure.c (print_closure, print_fderives): Likewise.

15434 2001-12-27 Akim Demaille <akim@epita.fr>
15436 * src/main.c (main): If there are complains after grammar
15437 reductions, then output the report anyway if requested, then die.
15438 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
15439 * src/reader.c (eoftoken): New.
15440 (parse_token_decl): If the token being defined has value `0', it
15442 (packsymbols): No longer hack `tags' to insert `$' by hand.
15443 Be sure to preserve the value of the eoftoken.
15444 (reader): Make sure eoftoken is defined.
15445 Initialize nsyms to 0: now eoftoken is created just like the others.
15446 * src/print.c (print_grammar): Don't special case the eof token.
15447 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
15448 lie anyway, albeit pleasant.
15449 * tests/calc.at: Exercise error messages with eoftoken.
15450 Change the grammar so that empty input is invalid.
15451 Adjust expectations.
15452 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
15454 2001-12-27 Akim Demaille <akim@epita.fr>
15456 * configure.in: Check the protos of strchr ans strspn.
15457 Replace strchr if needed.
15458 * src/system.h: Provide the protos of strchr, strspn and memchr if
15460 * lib/strchr.c: New.
15461 * src/reader.c (symbols_save): Use strchr.
15463 2001-12-27 Akim Demaille <akim@epita.fr>
15465 * src/print.c, src/print_graph.c (escape): New.
15466 Use it to quote the TAGS outputs.
15467 * src/print_graph.c (print_state): Now errors are in red, and
15468 reductions in green.
15469 Prefer high to wide: output the state number on a line of its own.
15471 2001-12-27 Akim Demaille <akim@epita.fr>
15473 * src/state.h, src/state.c (reductions_new): New.
15474 * src/LR0.c (set_state_table): Let all the states have a
15475 `reductions', even if reduced to 0.
15476 (save_reductions): Adjust.

15494 2001-12-27 Akim Demaille <akim@epita.fr>
15496 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
15497 * src/print.c: here.
15498 (lookaheadset, shiftset): New, used as additional storage by
15500 (print_results): Adjust.
15501 (print_shifts, print_gotos, print_errs): New, extracted from...
15502 (print_actions): here.
15503 * src/print_graph.c (print_actions): Remove dead code.
15505 2001-12-27 Akim Demaille <akim@epita.fr>
15507 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
15510 2001-12-27 Akim Demaille <akim@epita.fr>
15512 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
15513 (build_relations): Adjust.
15515 2001-12-27 Akim Demaille <akim@epita.fr>
15517 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
15520 2001-12-27 Akim Demaille <akim@epita.fr>
15522 * src/reader.c (packgram): Catch nitems overflows.
15524 2001-12-27 Akim Demaille <akim@epita.fr>
15526 * src/files.c, src/files.h (guard_obstack): Remove.
15527 * src/output.c (output): Adjust.
15528 * src/reader.c (parse_braces): New, factoring...
15529 (copy_action, copy_guard): these two which are renamed as...
15530 (parse_action, parse_guard): these.
15531 As a voluntary consequence, using braces around guards is now
15534 2001-12-27 Akim Demaille <akim@epita.fr>
15536 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
15537 * src/reader.c (symbol_list): `guard' and `guard_line' are new
15539 (symbol_list_new): Adjust.
15540 (copy_action): action_line is the first line, not the last.
15541 (copy_guard): Just as for actions, store the `action' only, not
15542 the switch/case/break flesh.
15543 Don't parse the user action that might follow the guard, let...
15544 (readgram): do it, i.e., now, there can be an action after a
15546 In other words the guard is just explicitly optional.
15547 (packgram): Adjust.
15548 * src/output.c (guards_output): New.
15549 (output_parser): Call it when needed.
15550 (output): Also free the guard and attrs obstacks.
15551 * src/files.c, src/files.h (obstack_save): Remove.
15552 (output_files): Remove.
15553 As a result, if one needs the former `.act' file, using an
15554 appropriate skeleton which requires actions and guards is now
15556 * src/main.c (main): Adjust.
15557 * tests/semantic.at: New.
15558 * tests/regression.at: Use `input.y' as input file name.
15559 Avoid 8+3 problems by requiring input.c when the test needs the

15564 * src/reader.c (symbol_list_new): Be sure to initialize all the
15567 2001-12-27 Akim Demaille <akim@epita.fr>
15569 All the hacks using a final pseudo state are now useless.
15571 * src/LR0.c (set_state_table): state_table holds exactly nstates.
15572 * src/lalr.c (nLA): New.
15573 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
15574 instead of lookaheadsp from the pseudo state (nstate + 1).
15576 2001-12-27 Akim Demaille <akim@epita.fr>
15578 * src/output.c (action_row, token_actions): Use a state_t instead
15579 of a integer, and nlookaheads instead of the following state's

15584 * src/conflicts.c (log_resolution, flush_shift)

15586 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
15587 (conflicts_print, print_reductions): Use a state_t instead of an
15588 integer when referring to a state.
15589 As much as possible, depend upon nlookaheads, instead of the
15590 `lookaheadsp' member of the following state (since lookaheads of
15591 successive states are successive, the difference between state n + 1
15592 and n served as the number of lookaheads for state n).
15593 * src/lalr.c (add_lookback_edge): Likewise.
15594 * src/print.c (print_core, print_actions, print_state)
15595 (print_results): Likewise.

15602 * src/bison.hairy: Formatting/comment changes.
15604 Remove `register' indications.
15605 Add plenty of `static'.
15607 2001-12-27 Akim Demaille <akim@epita.fr>
15609 * src/output.c (prepare): Drop the muscle `ntbase' which
15610 duplicates ntokens.
15611 * src/bison.simple: Formatting/comment changes.
15612 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
15613 is an undocumented synonym.
15615 2001-12-22 Akim Demaille <akim@epita.fr>
15617 * src/output.c (output_table_data): Change the prototype to use
15618 `int' for array ranges: some invocations do pass an int, not a
15620 Reported by Wayne Green.
15622 2001-12-22 Akim Demaille <akim@epita.fr>
15624 Some actions of web2c.y are improperly triggered.
15625 Reported by Mike Castle.
15627 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
15628 * tests/regression.at (Web2c): Rename as...
15629 (Web2c Report): this.
15630 (Web2c Actions): New.
15632 2001-12-22 Akim Demaille <akim@epita.fr>
15634 Reductions in web2c.y are improperly reported.
15635 Reported by Mike Castle.
15637 * src/conflicts.c (print_reductions): Fix.
15638 * tests/regression.at (Web2c): New.
15640 2001-12-18 Akim Demaille <akim@epita.fr>
15642 Some host fail on `assert (!"foo")', which expands to
15643 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
15644 Reported by Nelson Beebee.
15646 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
15647 `#define it_succeeded 0' and `assert (it_succeeded)'.
15649 2001-12-17 Marc Autret <autret_m@epita.fr>
15651 * src/bison.simple: Don't hard code the skeleton line and filename.
15652 * src/output.c (output_parser): Rename 'line' as 'output_line'.
15653 New line counter 'skeleton_line' (skeleton-line muscle).
15655 2001-12-17 Paul Eggert <eggert@twinsun.com>
15657 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
15658 YYDEBUG must be defined to a nonzero value.
15660 * src/bison.simple (yytname): Do not assume that the user defines
15661 YYDEBUG to a properly parenthesized expression.
15663 2001-12-17 Akim Demaille <akim@epita.fr>
15665 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
15666 nlookaheads is a new member.
15668 * src/lalr.h (nlookaheads): Remove this orphan declaration.
15669 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
15672 2001-12-17 Akim Demaille <akim@epita.fr>
15674 * src/files.h, src/files.c (open_files, close_files): Remove.
15675 * src/main.c (main): Don't open/close files, nor invoke lex_free,
15677 * src/reader.c (reader): Do it.
15679 2001-12-17 Akim Demaille <akim@epita.fr>
15681 * src/conflicts.c (print_reductions): Formatting changes.
15683 2001-12-17 Akim Demaille <akim@epita.fr>
15685 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
15686 (flush_reduce): New.
15687 (resolve_sr_conflict): Adjust.
15689 2001-12-17 Akim Demaille <akim@epita.fr>
15691 * src/output.c (output_obstack): Be static and rename as...
15692 (format_obstack): this, to avoid any confusion with files.c's
15694 * src/reader.h (muscle_obstack): Move to...
15695 * src/output.h: here, since it's defined in output.c.
15697 2001-12-17 Akim Demaille <akim@epita.fr>
15699 * src/output.c (action_row, save_column, default_goto)
15700 (sort_actions, matching_state, pack_vector): Better variable
15703 2001-12-17 Akim Demaille <akim@epita.fr>
15705 * src/output.c: Various formatting changes.
15707 2001-12-17 Akim Demaille <akim@epita.fr>
15709 * src/files.c (output_files): Free the output_obstack.
15710 * src/main.c (main): Call print and print_graph conditionally.
15711 * src/print.c (print): Work unconditionally.
15712 * src/print_graph.c (print_graph): Work unconditionally.
15713 * src/conflicts.c (log_resolution): Output only if verbose_flag.
15715 2001-12-16 Marc Autret <autret_m@epita.fr>
15717 * src/output.c (actions_output): Fix. When we use %no-lines,
15718 there is one less line per action.
15720 2001-12-16 Marc Autret <autret_m@epita.fr>
15722 * src/bison.simple: Remove a useless #line directive.
15723 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
15724 * src/output.c (get_lines_number): New.
15725 (output_parser): Adjust, now takes care about the lines of a
15727 Fix line numbering.
15728 (actions_output): Computes the number of lines taken by actions.
15729 (output_master_parser): Insert new skeleton which is the name of
15730 the output parser file name.
15732 2001-12-15 Marc Autret <autret_m@epita.fr>
15734 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
15736 2001-12-15 Marc Autret <autret_m@epita.fr>
15738 * src/output.c (output_gram): Keep track of the hairy one.
15740 2001-12-15 Akim Demaille <akim@epita.fr>
15742 Make `make distcheck' work.
15744 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
15745 system.h which uses libgettext.h.
15747 2001-12-15 Akim Demaille <akim@epita.fr>
15749 * src/nullable.c (set_nullable): Useless rules must be skipped,
15750 otherwise, since we range over their symbols, we might look at a
15751 nonterminal which no longer ``exists'', i.e., it is not counted in
15752 `nvars', hence we overflow our arrays.
15754 2001-12-15 Akim Demaille <akim@epita.fr>
15756 The header can also be produced directly, without any obstack!
15759 * src/files.c, src/files.h (defines_obstack): Remove.
15760 (compute_header_macro): Global.
15761 (defines_obstack_save): Remove.
15762 * src/reader.c (parse_union_decl): No longer output to
15763 defines_obstack: its content can be found in the `stype' muscle
15765 (output_token_translations): Merge into...
15766 (symbols_output): this.
15768 (symbols_save): this.
15770 * src/output.c (header_output): New.
15773 2001-12-15 Akim Demaille <akim@epita.fr>
15775 * src/reader.c (parse_union_decl): Instead of handling two obstack
15776 simultaneously, use one to define the `stype' muscle, and use the
15777 value of the latter to fill defines_obstack.
15778 (copy_comment): Remove.
15779 (copy_comment2): Work for a single obstack.
15781 (copy_comment): this.
15783 2001-12-15 Akim Demaille <akim@epita.fr>
15785 * src/lex.c, src/lex.h (xgetc): No longer static.
15786 * src/reader.c (parse_union_decl): Revamp.
15788 2001-12-15 Akim Demaille <akim@epita.fr>
15790 Still making progress in separating Bison into (i) input, (ii)
15791 process, (iii) output: now we can directly output the parser file
15792 without using table_obstack at all.
15794 * src/files.c, src/files.h (table_obstack): Bye bye.
15795 (parser_file_name): New.
15796 * src/files.c (compute_output_file_names): Compute it.
15797 * src/output.c (actions_output, output_parser)
15798 (output_master_parser): To a file instead of an obstack.
15800 2001-12-15 Akim Demaille <akim@epita.fr>
15802 Attach actions to rules, instead of pre-outputting them to
15805 * src/gram.h (rule_t): action and action_line are new members.
15806 * src/reader.c (symbol_list): Likewise.
15807 (copy_action): Save the actions within the rule.
15808 (packgram): Save them in rule_table.
15809 * src/output.c (actions_output): New.
15810 (output_parser): Use it on `%%actions'.
15811 (output_rule_data): Don't free rule_table.
15813 (prepare): Don't save the `action' muscle.
15814 * src/bison.simple: s/%%action/%%actions/.
15816 2001-12-15 Akim Demaille <akim@epita.fr>
15818 * src/reader.c (copy_action): When --yacc, don't append a `;'
15819 to the user action: let it fail if lacking.
15820 Suggested by Arnold Robbins and Tom Tromey.
15822 2001-12-14 Akim Demaille <akim@epita.fr>
15824 * src/lex.c (literalchar): Simply return the char you decoded, non
15825 longer mess around with obstacks and int pointers.
15826 Adjust all callers.
15828 2001-12-14 Akim Demaille <akim@epita.fr>
15830 * src/lex.c (literalchar): Don't escape the special characters,
15831 just decode them, and keep them as char (before, eol was output as
15832 the 2 char string `\n' etc.).
15833 * src/output.c (output_rule_data): Use quotearg to output the
15836 2001-12-13 Paul Eggert <eggert@twinsun.com>
15838 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
15839 Do not infringe on the global user namespace when using C++.
15840 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
15841 All uses of `fprintf' and `stderr' changed.
15843 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
15845 2001-12-13 Akim Demaille <akim@epita.fr>
15847 The computation of nullable is broken: it doesn't handle empty
15850 * tests/torture.at (GNU AWK Grammar): New.
15851 * tests/sets.at (Nullable): New.
15852 * src/nullable.c (set_nullable): Instead of blindly looping over
15853 `ritems', loop over the rules, and then over their rhs's.
15855 Work around Autotest bugs.
15857 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
15858 frame, because Autotest understand lines starting with a `+' as
15859 traces from the shell. Then, they are not processed properly.
15860 Admittedly an Autotest bug, but we don't have time to wait for
15861 Autotest to catch up.
15862 * tests/regression.at (Broken Closure): Adjust to the new table
15865 * tests/sets.at: here.
15867 2001-12-13 Akim Demaille <akim@epita.fr>
15869 * src/closure.c (closure): Use nrules instead of playing tricks
15870 with BITS_PER_WORD.
15872 2001-12-13 Akim Demaille <akim@epita.fr>
15874 * src/print.c (print_actions): Output the handling of `$' as the
15875 traces do: shifting the token EOF. Before EOF was treated as a
15877 * tests/regression.at: Adjust some tests.
15878 * src/print_graph.c (print_core): Complete the set of items via
15879 closure. The next-to-final and final states are still unsatisfying,
15880 but that's to be addressed elsewhere.
15881 No longer output the rule numbers, but do output the state number.
15882 A single loop for the shifts + gotos is enough, but picked a
15883 distinct color for each.
15884 (print_graph): Initialize and finalize closure.
15886 2001-12-13 Akim Demaille <akim@epita.fr>
15888 * src/reader.c (readgram): Remove dead code, an strip useless
15890 (get_type): Remove, unused.
15892 2001-12-12 Akim Demaille <akim@epita.fr>
15894 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
15895 on that of lib/error.c.
15897 2001-12-12 Akim Demaille <akim@epita.fr>
15899 Some hosts don't like `/' in includes.
15901 * src/system.h: Include libgettext.h without qualifying the path.
15902 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
15905 2001-12-11 Marc Autret <autret_m@epita.fr>
15907 * src/output.c (output_parser): Remove useless muscle.
15909 2001-12-11 Marc Autret <autret_m@epita.fr>
15911 * src/bison.simple: Remove #line just before %%epilogue. It
15912 is now handled in ...
15913 * src/reader.c (read_additionnal_code): Add the output of a
15914 #line for the epilogue.
15916 2001-12-10 Marc Autret <autret_m@epita.fr>
15918 * src/reader.c (copy_definition): Re-use CPP-outed code which
15919 replace precedent remove.
15920 * src/bison.simple: Remove #line before %%prologue because
15921 %%input-line is wrong at this time.
15923 2001-12-10 Marc Autret <autret_m@epita.fr>
15925 * src/reader.c (symbols_output): Clean up.
15926 * src/output.c (output_gram, output): Clean up.
15928 2001-12-10 Akim Demaille <akim@epita.fr>
15930 * src/lalr.c (initialize_lookaheads): New. Extracted from...
15931 * src/LR0.c (set_state_table): here.
15932 * src/lalr.c (lalr): Call it.
15934 2001-12-10 Akim Demaille <akim@epita.fr>
15936 * src/state.h (shifts): Remove the `number' member: shifts are
15937 attached to state, hence no longer need to be labelled with a
15940 2001-12-10 Akim Demaille <akim@epita.fr>
15942 Now that states have a complete set of members, the linked list of
15943 shifts is useless: just fill directly the state's shifts member.
15945 * src/state.h (shifts): Remove the `next' member.
15946 * src/LR0.c (first_state, last_state): Remove.
15947 Adjust the callers.
15948 (augment_automaton): Don't look for the shifts that must be added
15949 a shift on EOF: it is those of the state we looked for! But now,
15950 since shifts are attached, it is no longer needed to looking
15951 merely by its id: its number.
15953 2001-12-10 Akim Demaille <akim@epita.fr>
15955 * src/LR0.c (augment_automaton): Better variable locality.
15956 Remove an impossible branch: if there is a state corresponding to
15957 the start symbol being shifted, then there is shift for the start
15958 symbol from the initial state.
15960 2001-12-10 Akim Demaille <akim@epita.fr>
15962 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
15963 only when appropriate: when insert_start_shifting_state' is not
15965 * tests/regression.at (Rule Line Numbers): Adjust.
15967 2001-12-10 Akim Demaille <akim@epita.fr>
15969 * src/LR0.c (augment_automaton): Now that all states have shifts,
15970 merge the two cases addition shifts to the initial state.
15972 2001-12-10 Akim Demaille <akim@epita.fr>
15974 * src/lalr.c (set_state_table): Move to...
15976 * src/lalr.c (lalr): Don't call it...
15977 * src/LR0.c (generate_states): do it.
15978 * src/LR0.h (first_state): Remove, only the table is used.
15980 2001-12-10 Akim Demaille <akim@epita.fr>
15982 * src/LR0.h (first_shift, first_reduction): Remove.
15983 * src/lalr.c: Don't use first_shift: find shifts through the
15986 2001-12-10 Akim Demaille <akim@epita.fr>
15988 * src/LR0.c: Attach shifts to states as soon as they are
15990 * src/lalr.c (set_state_table): Instead of assigning shifts to
15991 state, just assert that the mapping was properly done.
15993 2001-12-10 Akim Demaille <akim@epita.fr>
15995 * src/LR0.c (insert_start_shift): Rename as...
15996 (insert_start_shifting_state): this.
15997 (insert_eof_shifting_state, insert_accepting_state): New.
15998 (augment_automaton): Adjust.
15999 Better locality of the variables.
16000 When looking if the start_symbol is shifted from the initial
16001 state, using `while (... symbol != start_symbol ...)' sounds
16002 better than `while (... symbol < start_symbol ...)': If fail
16003 to see how the order between symbols could be relevant!
16005 2001-12-10 Akim Demaille <akim@epita.fr>
16007 * src/getargs.h: Don't declare `spec_name_prefix' and
16008 `spec_file_prefix', declared by src/files.h.
16009 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
16010 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
16011 * src/output.c (prepare): Adjust.
16012 * src/reader.c (symbols_output): Likewise.
16013 * src/vmsgetargs.c: Vaguely adjust, but who cares?
16015 2001-12-10 Akim Demaille <akim@epita.fr>
16017 * src/muscle_tab.c (muscle_init): NULL is a better default than
16020 2001-12-10 Akim Demaille <akim@epita.fr>
16022 * src/reader.c (reader): Calling symbols_output once is enough.
16024 2001-12-10 Akim Demaille <akim@epita.fr>
16026 Now that states have a complete set of members, the linked list of
16027 reductions is useless: just fill directly the state's reductions
16030 * src/state.h (struct reductions): Remove member `number' and
16032 * src/LR0.c (first_reduction, last_reduction): Remove.
16033 (save_reductions): Don't link the new reductions, store them in
16035 * src/lalr.c (set_state_table): No need to attach reductions to
16036 states, it's already done.
16037 * src/output.c (output_actions): No longer free the shifts, then
16038 the reductions, then the states: free all the states and their
16041 2001-12-10 Akim Demaille <akim@epita.fr>
16043 * src/options.c (OPTN, DRTV, BOTH): New.
16044 (option_table): Use them.
16046 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
16047 the job of system.h.
16048 * src/options.c: Don't include stdio.h and xalloc.h for the same
16051 2001-12-10 Akim Demaille <akim@epita.fr>
16053 * src/output.c (output, prepare): Make sure the values of the
16054 muscles `action' and `prologue' are 0-terminated.
16056 2001-12-10 Akim Demaille <akim@epita.fr>
16058 Clean up GCC warnings.
16060 * src/reader.c (copy_action): `buf' is not used.
16061 (parse_skel_decl): Be static.
16062 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
16063 * src/options.h (create_long_option_table): Have a real prototype.
16064 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
16065 (hash_delete_at): Return const void *.
16066 Adjust casts to preserve the const.
16068 2001-12-10 Akim Demaille <akim@epita.fr>
16070 * configure.in: Require 2.52g.
16071 M4 is not needed, but AUTOM4TE is.
16072 * m4/m4.m4: Remove.
16073 * tests/Makefile.am: Adjust.
16075 2001-12-10 Akim Demaille <akim@epita.fr>
16077 One structure for states is enough, even though theoretically
16078 there are LR(0) states and LALR(1) states.
16080 * src/lalr.h (state_t): Remove.
16081 (state_table): Be state_t **, not state_t *.
16082 * src/state.h (core, CORE_ALLOC): Rename as...
16083 (state_t, STATE_ALLOC): this.
16084 Add the LALR(1) members: shifts, reductions, errs.
16085 * src/LR0.c (state_table): Rename as...
16086 (state_hash): this, to avoid name clashes with the global
16088 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
16089 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
16091 2001-12-10 Akim Demaille <akim@epita.fr>
16093 Bison dumps core on bash.y.
16094 Reported by Pascal Bart.
16096 * src/warshall.c (bitmatrix_print): New.
16098 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
16099 j must be the outer loop.
16100 * tests/regression.at (Broken Closure): New.
16102 2001-12-05 Akim Demaille <akim@epita.fr>
16104 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
16106 Reported by Peter Hamorsky.
16108 2001-12-05 Akim Demaille <akim@epita.fr>
16110 * src/conflicts.c (err_table): Remove.
16111 (resolve_sr_conflict): Adjust.
16112 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
16114 (state_t.reductions, state_t.shifts): this.
16116 2001-12-05 Akim Demaille <akim@epita.fr>
16118 * src/reduce.c (reduce_grammar_tables): No longer disable the
16119 removal of useless rules via CPP but via `if (0)', so that the
16120 compiler still check the code is valid.
16121 For instance, it should have noticed `rline' no longer exists: use
16122 the `line' member of rule_t.
16123 * src/gram.c (dummy, rline): Remove, unused.
16125 2001-12-05 Akim Demaille <akim@epita.fr>
16127 * src/output.c (pack_vector): Use assert, not berror.
16128 * src/main.c (berror): Remove, unused.
16130 2001-12-05 Akim Demaille <akim@epita.fr>
16132 New experimental feature: if --verbose --trace output all the
16133 items of a state, not only its kernel.
16135 * src/print.c (print_core): If `trace_flag', then invoke closure
16136 before outputting the items of the state (print_core is no longer
16137 a correct name them).
16138 (print_results): Invoke new_closure/free_closure if needed.
16140 2001-12-05 Akim Demaille <akim@epita.fr>

16149 (closure): Use it for printing input and output.
16151 2001-12-05 Akim Demaille <akim@epita.fr>
16153 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
16154 indexed by nonterminals.
16156 2001-12-05 Akim Demaille <akim@epita.fr>
16158 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

16177 using the good o' techniques: arrays not pointers, variable
16178 locality, BITISSET, RESETBIT etc.
16180 2001-12-05 Akim Demaille <akim@epita.fr>
16182 Pessimize the code to simplify it: from now on, all the states
16183 have a valid SHIFTS, which NSHIFTS is possibly 0.
16185 * src/LR0.c (shifts_new): Be global and move to..
16186 * src/state.c, src/state.h: here.
16187 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
16188 * src/print_graph: Adjust.

16192 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
16193 * src/conflicts.c: Use it.
16194 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
16195 incorrectly ``simplified''.
16197 2001-12-05 Akim Demaille <akim@epita.fr>
16199 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
16200 using the good o' techniques: arrays not pointers, variable
16201 locality, BITISSET, RESETBIT etc.
16203 2001-12-05 Akim Demaille <akim@epita.fr>
16205 * src/state.h (SHIFT_SYMBOL): New.

16235 2001-12-05 Akim Demaille <akim@epita.fr>
16237 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
16238 * src/lalr.c: Use them.
16240 2001-12-05 Akim Demaille <akim@epita.fr>
16242 * src/LR0.c (augment_automaton): Formatting changes.
16243 Better variable locality.

16253 * src/lalr.c (maxrhs): Move to...
16254 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
16255 * src/lalr.c (build_relations): Adjust.
16257 2001-12-05 Akim Demaille <akim@epita.fr>
16259 * src/lalr.c (transpose): Free the memory allocated to the
16260 argument, as it is replaced by the results by the unique caller.
16261 (build_relations): Merely invoke transpose: it handles the memory
16263 Improve variable locality.
16264 Avoid variables used as mere abbreviations.
16265 (compute_lookaheads): Use arrays instead of pointers.
16267 2001-12-05 Akim Demaille <akim@epita.fr>
16269 * src/lalr.c (initialize_F): Improve variable locality.
16270 Avoid variables used as mere abbreviations.
16272 2001-12-05 Akim Demaille <akim@epita.fr>
16274 * src/derives.c (print_derives): Display the ruleno.

16283 2001-12-05 Akim Demaille <akim@epita.fr>
16285 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
16286 the handling of squeue.
16287 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16289 2001-12-05 Akim Demaille <akim@epita.fr>
16291 Because useless nonterminals are now kept alive (instead of being
16292 `destroyed'), we now sometimes examine them, and store information
16293 related to them. Hence we need to know their number, and adjust
16294 memory allocations.
16296 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
16298 * src/LR0.c (allocate_itemsets): The memory allocated to
16299 `symbol_count' was used for two different purpose: once to count
16300 the number of occurrences of each symbol, and later reassigned to
16301 `shift_symbol', containing the symbol that can be shifted from a
16303 Deobfuscate, i.e., allocate, use and free `symbol_count' here
16305 (new_itemsets): Allocate `shift_symbol' here.
16306 (allocate_itemsets): symbol_count includes useless nonterminals.
16307 Make room for them.
16308 (free_storage): Use `free', not `XFREE', for pointers that cannot
16311 2001-12-05 Akim Demaille <akim@epita.fr>
16313 * src/nullable.c (set_nullable): Deobfuscate the handling of
16315 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16317 2001-12-05 Akim Demaille <akim@epita.fr>
16319 * src/gram.c, src/gram.h (ritem_print): New.
16320 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
16321 (This useless function was defined only to work around VMS linkers
16322 that can't handle compilation units with variables only).
16323 * src/reduce.c (dump_grammar): Use it to trace the construction of
16326 2001-12-04 Paul Eggert <eggert@twinsun.com>
16328 * src/bison.simple (union yyalloc): Change member names
16329 to be the same as the stack names.
16330 (yyparse): yyptr is now union yyalloc *, not char *.
16331 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
16332 and may generate better code on some machines.
16333 (yystpcpy): Use prototype if __STDC__ is defined, not just
16334 if __cplusplus is defined.
16336 2001-11-30 Akim Demaille <akim@epita.fr>
16338 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
16339 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
16340 Gettext doesn't compile cleanly, and dies with -Werror.
16341 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
16342 Include WARNING_CFLAGS here.
16343 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
16344 before being defined.
16346 2001-11-27 Paul Eggert <eggert@twinsun.com>
16348 * lib/quotearg.h (quotearg_n, quotearg_n_style):
16349 First arg is int, not unsigned.
16350 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
16351 (SIZE_MAX, UINT_MAX): New macros.
16352 (quotearg_n_options): Abort if N is negative.
16353 Avoid overflow check on hosts where size_t is 64 bits and int
16354 is 32 bits, as overflow is impossible there.
16355 Fix off-by-one typo that caused unnecessary reallocation.
16357 2001-11-29 Paul Eggert <eggert@twinsun.com>
16359 Name space cleanup in generated parser.
16361 * doc/bison.texinfo (Bison Parser): Discuss system headers
16362 and their effect on the user name space.
16364 * src/bison.simple:
16365 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
16366 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
16367 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
16369 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
16370 on user names when possible.
16372 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
16373 Simplify test for whather <alloca.h> exists.
16375 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
16377 (<stdio.h>): Include if YYDEBUG.
16379 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
16380 ! defined (yyoverflow) && ! defined (yymemcpy).
16382 (yymemcpy, yyparse): Rename local variables as needed so that
16383 they all begin with 'yy'.
16385 (yystrlen, yystpcpy): New functions.
16387 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
16390 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
16391 instead of relying on string.h functions. Use YYSTACK_ALLOC
16392 and YYSTACK_FREE instead of malloc and free.
16394 2001-11-30 Akim Demaille <akim@epita.fr>
16396 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
16397 before their first uses.

16407 if body instead of `;' to pacify GCC's warnings.
16409 2001-11-30 Akim Demaille <akim@epita.fr>
16411 Instead of mapping the LHS of unused rules to -1, keep the LHS
16412 valid, but flag the rules as invalid.
16414 * src/gram.h (rule_t): `useful' is a new member.
16415 * src/print.c (print_grammar): Adjust.
16416 * src/derives.c (set_derives): Likewise.
16417 * src/reader.c (packgram, reduce_output): Likewise.
16418 * src/reduce.c (reduce_grammar_tables): Likewise.
16419 * tests/reduce.at (Underivable Rules, Useless Rules): New.
16421 2001-11-30 Akim Demaille <akim@epita.fr>

16428 2001-11-30 Akim Demaille <akim@epita.fr>
16430 * src/reduce.c (nonterminals_reduce): Instead of throwing away
16431 useless nonterminals, move them at the end of the symbol arrays.
16432 (reduce_output): Adjust.
16433 * tests/reduce.at (Useless Nonterminals): Adjust.
16435 2001-11-30 Akim Demaille <akim@epita.fr>

16445 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
16446 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
16448 (union yyalloc): New type.
16449 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
16450 an arbitrary restriction on hosts where size_t is wider than int.
16452 (yyparse): Don't dump core if alloca or malloc fails; instead, report
16453 a parser stack overflow. Allocate just one block of memory for all
16454 three stacks, instead of allocating three blocks; this typically is
16455 faster and reduces fragmentation.
16457 Do not limit the number of items in the stack to a value that fits
16458 in 'int', as this is an arbitrary limit on hosts with 64-bit
16459 size_t and 32-bit int.
16461 2001-11-29 Marc Autret <autret_m@epita.fr>
16463 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
16464 of defining YYERROR_VERBOSE.

16514 2001-11-28 Akim Demaille <akim@epita.fr>
16516 * src/closure.c (closure): Instead of looping over word in array
16517 then bits in words, loop over bits in array.
16519 2001-11-28 Akim Demaille <akim@epita.fr>
16521 * src/closure.c (closure): No longer optimize the special case
16522 where all the bits of `ruleset[r]' are set to 0, to make the code
16525 2001-11-28 Akim Demaille <akim@epita.fr>
16527 * src/closure.c (closure): `r' and `c' are new variables, used to

16546 2001-11-27 Paul Eggert <eggert@twinsun.com>
16548 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

16891 use abs. path to find config.h.
16892 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

18264 * src/conflicts.c (conflict_report): Be sure not to append to res
18265 between two calls, which could happen if both first sprintf were

18270 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
18271 New, from fileutils 4.0.37.
18272 * configure.in: Require Autoconf 2.49c. I took some time before
18273 making this decision. This is the only way out for portability
18274 issues in Bison, it would mean way too much duplicate effort to
18275 import in Bison features implemented in 2.49c since 2.13.
18276 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
18278 2001-02-02 Akim Demaille <akim@epita.fr>

18295 * src/lex.h: Rename all the tokens:
18296 s/\bENDFILE\b/tok_eof/g;
18297 s/\bIDENTIFIER\b/tok_identifier/g;
18299 Let them be enums, not #define, to ease debugging.

18318 * src/files.c (open_files): Don't call `compute_base_names', don't

18322 * src/output.c (output_headers): Document the fact that this patch
18323 introduces a guaranteed SEGV for semantic parsers.
18324 * doc/bison.texinfo: Document them.
18325 * tests/suite.at: Exercise these %options.
18327 2000-12-20 Akim Demaille <akim@epita.fr>

18392 (obstack_grow_string): this.
18393 * src/output.c (output_parser): Recognize `%% actions' instead of
18395 * src/bison.s1: s/$/%% actions/.
18396 * src/bison.hairy: Likewise.
18398 2000-12-19 Akim Demaille <akim@epita.fr>
18400 * src/output.c (output_parser): Compute the `#line' lines when

18427 * src/files.c (open_files): Yipee! We no longer need all the code

18432 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

18459 * lib/obstack.h: Formatting changes.
18460 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
18461 prevents type checking.
18462 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

18466 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

18485 Use them to declare the variables which are global or local to
18488 2000-11-17 Akim Demaille <akim@epita.fr>
18490 * acconfig.h: Remove, no longer used.
18492 2000-11-07 Akim Demaille <akim@epita.fr>
18494 * src: s/Copyright (C)/Copyright/g.
18496 2000-11-07 Akim Demaille <akim@epita.fr>
18498 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
18500 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

18516 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
18517 `const' their input argument (`data' or `address').
18518 Adjust the corresponding macros to include `const' in casts.

18522 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

18542 * src/files.c (obstack_save): New function.
18543 (done): Rename as...
18544 (output_files): this.
18545 Use `obstack_save'.
18546 * src/main.c (main): Don't use `atexit' to register `done', since
18547 it no longer has to remove tmp files, just call `output_files'
18548 when there are no errors.
18550 2000-11-02 Akim Demaille <akim@epita.fr>
18552 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
18553 `unlink': it's no longer used.
18554 * src/files.h: Formatting changes.
18556 2000-11-02 Akim Demaille <akim@epita.fr>
18558 Remove the last uses of mktemp and unlink/delete.
18560 * src/files.c (fdefines, ftable): Removed.
18561 (defines_ostack, table_obstack): New.

18620 * src/reader.c (copy_comment2): Expect the input stream to be on
18621 the `/' which is suspected to open a comment, instead of being
18622 called after `//' or `/*' was read.
18623 (copy_comment, copy_definition, parse_union_decl, copy_action)
18624 (copy_guard): Adjust.
18626 2000-10-16 Akim Demaille <akim@epita.fr>
18628 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

18634 (copy_guard, copy_action): Use it.
18636 2000-10-16 Akim Demaille <akim@epita.fr>
18638 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
18639 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
18640 New files, from Fileutils 4.0.27.
18641 * src/main.c (printable_version): Remove.

18648 2000-10-04 Akim Demaille <akim@epita.fr>
18650 * doc/bison.texinfo: Various typos spotted by Neil Booth.
18652 2000-10-04 Akim Demaille <akim@epita.fr>
18654 When a literal string is used to define two different tokens,
18655 `bison -v' segfaults.
18656 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
18658 * tests/regression.m4: New file.
18659 Include the core of the sample provided by Piotr Gackiewicz.
18660 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed

18683 translation, move some `\n' out of the translated strings.
18685 2000-10-02 Akim Demaille <akim@epita.fr>
18687 The location tracking mechanism is precious for parse error
18688 messages. Nevertheless, it is enabled only when `@n' is used in
18689 the grammar, which is a different issue (you can use it in error
18690 message, but not in the grammar per se). Therefore, there should
18691 be another means to enable it.
18693 * src/getargs.c (getargs): Support `--locations'.
18694 (usage): Report it.
18695 * src/getargs.h (locationsflag): Export it.

18703 For regularity of the names, replace each
18704 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
18705 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
18706 In addition replace each `flag' with `_flag'.
18708 2000-10-02 Akim Demaille <akim@epita.fr>
18710 Also test parse error messages, including with YYERROR_VERBOSE.
18712 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
18714 Use it to check the computations.
18715 Use it to check `nonassoc' is honored.
18716 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
18717 `--yyerror-verbose'.
18718 (_AT_CHECK_CALC): Adjust to this option.

18723 Test also `--verbose', `--defines' and `--name-prefix'. Testing
18724 the latter demonstrates a flaw in the handling of non debugging
18725 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
18726 was used in order to simplify:
18742 unfortunately this leads to a CPP conflict when
18743 `--name-prefix=foo' is used since it produces `#define yydebug
18746 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
18747 (YYDPRINTF): New macro.
18749 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
18751 Also test `--verbose', `--defines' and `--name-prefix'.
18753 2000-10-02 Akim Demaille <akim@epita.fr>
18755 Improve the readability of the produced parsers.
18757 * src/bison.s1: Formatting changes.
18758 Improve the comment related to the `$' mark.
18759 (yydefault): Don't fall through to `yyresume': `goto' there.
18760 * src/output.c (output_parser): When the `$' is met, skip the end
18762 New variable, `number_of_dollar_signs', to check there's exactly
18763 one `$' in the parser skeleton.
18765 2000-10-02 Akim Demaille <akim@epita.fr>
18767 * lib/xstrdup.c: New file, from the fileutils.
18768 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
18769 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
18770 instead of strlen + xmalloc + strcpy.
18771 * src/symtab.c (copys): Remove, use xstrdup instead.
18773 2000-10-02 Akim Demaille <akim@epita.fr>
18775 * src/gram.h (associativity): New enum type which replaces the
18776 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
18777 `right_assoc', `left_assoc' and `non_assoc'.
18778 Adjust all dependencies.
18779 * src/reader.c: Formatting changes.
18780 (LTYPESTR): Don't define it, use it as a literal in
18781 `reader_output_yylsp'.
18782 * src/symtab.h (symbol_class): New enum type which replaces the
18783 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
18784 `sunknown', `stoken and `snterm'.
18786 2000-10-02 Akim Demaille <akim@epita.fr>

18789 (yaccflag): for consistency and accuracy.
18790 Adjust dependencies.
18792 2000-10-02 Akim Demaille <akim@epita.fr>
18794 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
18795 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
18796 difficult and introduced a lot of core dump. It turns out that
18797 Bison used an implementation of `xmalloc' based on `calloc', and
18798 at various places it does depend upon the initialization to 0. I
18799 have not tried to isolate the pertinent places, and all the former
18800 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
18801 someone should address this issue.
18803 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
18804 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

18816 2000-10-02 Akim Demaille <akim@epita.fr>
18818 * src/state.h (nstates, final_state, first_state, first_shift)
18819 (first_reduction): Move their exportation from here...
18820 * src/LR0.h: to here.
18821 Adjust dependencies.
18822 * src/getargs.c (statisticsflag): New variable.
18823 Add support for `--statistics'.

18860 Propagate its inclusion.
18861 * src/reduce.c: Topological sort and other formatting changes.
18862 (bool, TRUE, FALSE): Move their definition to...

18867 * src/files.c: Formatting changes.

18898 * src/output.c (token_actions): Introduce a temporary array,
18899 YYDEFACT, that makes it possible for this function to use
18900 output_short_table.
18902 2000-10-02 Akim Demaille <akim@epita.fr>
18904 `user_toknums' is output as a `short[]' in `output.c', while it is
18905 defined as a `int[]' in `reader.c'. For consistency with the
18906 other output tables, `user_toknums' is now defined as a table of

18949 Don't define PARAMS.
18950 * src/system.h: Define PARAMS.
18951 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
18952 purpose of config.h. system.h must not try to fix wrong
18953 definitions in config.h.

19169 2000-03-17 Akim Demaille <akim@epita.fr>
19171 Change the handling of @s so that they behave exactly like $s.
19172 There is now a pseudo variable @$ (readble and writable), location
19173 of the lhs of the rule (by default ranging from the location of
19174 the first symbol of the rhs, to the location of the last symbol,
19175 or, if the rhs is empty, YYLLOC).
19177 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
19179 (yyparse): When providing a default semantic action, provide a
19180 default location action.
19181 (after the $): No longer change `*YYLSP', just stack YYLOC the
19182 same way you stack YYVAL.
19183 * src/reader.c (read_declarations): Use warns.
19184 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
19185 (copy_action, case '@'): Likewise.

19209 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
19210 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
19211 One `#if YYDEBUG' remains, since it uses variables which are
19212 defined only if `YYDEBUG != 0'.
19214 2000-03-16 Akim Demaille <akim@epita.fr>
19216 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

19236 Bump to bison 1.28a, 1.29 has never been released.
19237 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
19238 handled via src/Makefile.am.

19875 * src/symtab.h (SALIAS):
19876 New #define for adding aliases to %token.
19877 (struct bucket): Added `alias' field.
19879 * src/reduce.c (reduce_grammar):
19880 Revise error message.
19881 (print_notices): Remove final `.' from error message.
19883 * src/reader.c (reader_output_yylsp):
19885 (readgram): Use `#if 0' around code that accepted %command
19886 inside grammar rules: The documentation doesn't allow it,
19887 and it will fail since the %command processors scan for the next %.
19888 (parse_token_decl): Extended the %token
19889 declaration to allow a multi-character symbol as an alias.
19890 (parse_thong_decl): New function.
19891 (read_declarations): Added %thong declarations.
19892 (read_declarations): Handle NOOP to deal with allowing
19893 % declarations as another means to specify the flags.
19894 (readgram): Allow %prec prior to semantics embedded in a rule.
19895 (skip_to_char, read_declarations, copy_definition)
19896 (parse_token_decl, parse_start_decl, parse_type_decl)
19897 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
19898 (get_type_name, copy_guard, copy_action, readgram)
19899 (get_type, packsymbols): Revised most error messages.
19900 Changed `fatal' to `warnxxx' to avoid aborting for error.
19901 Revised and use multiple warnxxx functions to avoid using VARARGS1.
19902 (read_declarations): Improve the error message for
19903 an invalid character. Do not abort.
19904 (read_declarations, copy_guard, copy_action): Use
19905 printable_version to avoid unprintable characters in printed output.
19906 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
19907 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
19908 Allow the type of a non-terminal can be given
19909 more than once, as long as all specifications give the same type.
19912 (output_headers, output_trailers, output, output_gram)
19913 (output_rule_data): Implement noparserflag variable.
19914 Implement toknumflag variable.
19915 (output): Call reader_output_yylsp to output LTYPESTR.
19917 * src/main.c (main):
19918 If reader sees an error, don't process the grammar.
19919 (fatals): Updated to not use VARARGS1.
19920 (printable_version, int_to_string, warn, warni, warns, warnss)
19921 (warnsss): New error reporting functions. Avoid abort for error.
19924 Added THONG and NOOP for alias processing.
19925 Added SETOPT for the new code that allows setting options with %flags.
19928 Include getopt.h. Add some extern decls.
19929 (safegetc): New function to deal with EOF gracefully.
19930 (literalchar); new function to deal with reading \ escapes.
19931 (lex): Use literalchar.
19932 (lex): Implemented "..." tokens.
19933 (literalchar, lex, parse_percent_token): Made tokenbuffer
19934 always contain the token. This includes growing the token
19935 buffer while reading an integer.
19936 (parse_percent_token): Replaced if-else statement with percent_table.
19937 (parse_percent_token): Added % declarations as another
19938 way to specify the flags -n, -l, and -r. Also added hooks for
19939 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
19940 major changes to files.c.
19941 (lex) Retain in the incoming stream a character following
19943 (skip_white_space, lex): Revised most error messages
19944 and changed fatal to warn to avoid aborting.
19945 (percent_table): Added %thong declarations.
19947 * src/gram.h: Comment changes.
19949 * src/files.c (openfiles, open_extra_files, done):
19951 and actfile file. Handle noparserflag. Both for -n switch.
19953 * src/conflicts.c (resolve_sr_conflict):
19954 Remove use of alloca.
