198
199 Remove the support for C++ namespace cleanliness; it was

291 * src/output.c (actions_output, guards_output)
292 (token_definitions_output): No longer keeps track of the output

295 action member.
296 Adjust callers.
297 (output_skeleton): Don't look for the skeleton location, let m4 do
298 that.

300 file will be used.
301 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
302 (prepare): Given that for the time being changesyntax is not
303 usable in M4, rename the muscles using `-' to `_'.

314 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
315 shamelessly stolen from CVS Autoconf.

333 2002-01-29 Paul Eggert <eggert@twinsun.com>
334
335 * src/bison.simple (YYSIZE_T): Do not define merely because
336 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
337 On some platforms, <alloca.h> does not declare YYSTD (size_t).
338
339 2002-01-27 Akim Demaille <akim@epita.fr>
340
341 Fix `%nonassoc and eof'.
342
343 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
344 which were not properly copied! Replace
345 memcpy (res->errs, src->errs, src->nerrs);
346 with
347 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
348 !!!
349 * tests/regression.at (%nonassoc and eof): Adjust to newest
350 Autotest: `.' is not in the PATH.

483 2002-01-06 Akim Demaille <akim@epita.fr>
484
485 Creating package.m4 from configure.ac causes too many problems.
486
487 * tests/Makefile.am (package.m4): Create it by hand,
488 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
489
490 2002-01-06 Akim Demaille <akim@epita.fr>
491
492 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
493 skeleton.h.
494
495 2002-01-04 Paul Eggert <eggert@twinsun.com>
496
497 * doc/bison.texinfo (Debugging):
498 Remove YYSTDERR; it's no longer defined or used.
499 Also, s/cstdio.h/cstdio/.
500
501 2002-01-03 Akim Demaille <akim@epita.fr>
502
503 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
504
505 2002-01-03 Akim Demaille <akim@epita.fr>
506
507 * src/parse-skel.y (process_skeleton): Don't bind the parser's
508 tracing code to --trace, wait for a better --trace option, with
509 args.
510
511 2002-01-03 Akim Demaille <akim@epita.fr>
512
513 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
514 The ISO C++ standard is extremely clear about it: stderr is
515 considered a macro, not a regular symbol (see table 94 `Header
516 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
517 Therefore std:: does not apply to it. It still does with fprintf.
518 Also, s/cstdio.h/cstdio/.
519
520 2002-01-03 Akim Demaille <akim@epita.fr>
521
522 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
523 for non system headers.
524
525 2002-01-02 Akim Demaille <akim@epita.fr>
526
527 Equip the skeleton chain with location tracking, runtime trace,
528 pure parser and scanner.
529
530 * src/parse-skel.y: Request a pure parser, locations, and prefix
531 renaming.
532 (%union): Having several members with the same type does not help
533 type mismatches, simplify.
534 (YYPRINT, yyprint): New.
535 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
536 (skel_error): this.
537 Handle locations.
538 * src/scan-skel.l: Adjust to these changes.
539 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
540 (LOCATION_PRINT, skel_control_t): New.
541
542 2001-12-30 Akim Demaille <akim@epita.fr>
543
544 * src/parse-skel.y: Get rid of the shift/reduce conflict:
545 replace `gb' with BLANKS.
546 * src/scan-skel.l: Adjust.
547
548 2001-12-30 Akim Demaille <akim@epita.fr>
549
550 * src/system.h: We don't need nor want bcopy.
551 Throw away MS-DOS crap: we don't need getpid.
552 * configure.in: We don't need strndup. It was even causing
553 problems: because Flex includes the headers *before* us,
554 _GNU_SOURCE is not defined by config.h, and therefore strndup was
555 not visible.
556 * lib/xstrndup.c: New.
557 * src/scan-skel.l: Use it.
558 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
559 * src/parse-skel.y: Use %directives instead of #defines.
560
561 2001-12-30 Akim Demaille <akim@epita.fr>
562
563 * src/skeleton.h: New.
564 * src/output.c (output_parser, output_master_parser): Remove, dead
565 code.
566 * src/output.h (get_lines_number, actions_output, guards_output)
567 (token_definitions_output): Prototype them.
568 * src/parse-skel.y: Add the license notice.
569 Include output.h and skeleton.h.
570 (process_skeleton): Returns void, and takes a single parameter.
571 * src/scan-skel.l: Add the license notice.
572 Include skeleton.h.
573 Don't use %option yylineno: it seems that then Flex imagines
574 REJECT has been used, and therefore it won't reallocate its
575 buffers (which makes no other sense to me than a bug). It results
576 in warnings for `unused: yy_flex_realloc'.
577
578 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
579
580 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
581 (MUSCLE_INSERT_PREFIX): ...to there.
582 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
583 (MUSCLE_INSERT_PREFIX): Move from here...
584
585 * src/bison.hairy: Add a section directive. Put braces around muscle
586 names. This parser skeleton is still broken, but Bison should not
587 choke on a bad muscle 'syntax'.
588 * src/bison.simple: Add a section directive. Put braces around muscle
589 names.
590
591 * src/files.h (strsuffix, stringappend): Add declarations.
592 (tab_extension): Add declaration.
593 (short_base_name): Add declaration.
594
595 * src/files.c (strsuffix, stringappend): No longer static. These
596 functions are used in the skeleton parser.
597 (tab_extension): New.
598 (compute_base_names): Use the computations done in this function
599 to guess if the generated parsers should have '.tab' in their
600 names.
601 (short_base_name): No longer static.
602
603 * src/output.c (output_skeleton): New.
604 (output): Disable call to output_master_parser, and give a try to
605 a new skeleton handling system.
606 (guards_output, actions_output): No longer static.
607 (token_definitions_output, get_lines_number): No longer static.
608
609 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
610
611 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
612 parse-skel.y.
613
614 * src/parse-skel.y: New file.
615 * src/scan-skel.l: New file.
616
617 2001-12-29 Akim Demaille <akim@epita.fr>
618
619 %name-prefix is broken.
620
621 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
622 Adjust all dependencies.
623 * tests/headers.at (export YYLTYPE): Strengthen this test: use
624 %name-prefix.
625
626 Renaming yylval but not yylloc is not consistent. Now we do.
627
628 * src/bison.simple: Prefix yylloc if used.
629 * doc/bison.texinfo (Decl Summary): Document that.
630
631 2001-12-29 Akim Demaille <akim@epita.fr>
632
633 * doc/bison.texinfo: Promote `%long-directive' over
634 `%long_directive'.
635 Remove all references to fixed-output-files, yacc is enough.
636
637 2001-12-29 Akim Demaille <akim@epita.fr>
638
639 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
640 user prologue. These are defaults.
641 * tests/actions.at (Mid-rule actions): Make sure the user can
642 define YYDEBUG and YYERROR_VERBOSE.
643
644 2001-12-29 Akim Demaille <akim@epita.fr>
645
646 * src/output.c (header_output): Don't forget to export YYLTYPE and
647 yylloc.
648 * tests/headers.at (export YYLTYPE): New, make sure it does.
649 * tests/regression.at (%union and --defines, Invalid CPP headers):
650 Move to...
651 * tests/headers.at: here.
652
653 2001-12-29 Akim Demaille <akim@epita.fr>
654
655 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
656
657 2001-12-29 Akim Demaille <akim@epita.fr>
658
659 * tests/actions.at (Mid-rule actions): Output on a single line
660 instead of several.
661
662 2001-12-29 Akim Demaille <akim@epita.fr>
663
664 * doc/bison.texinfo: Formatting changes.
665
666 2001-12-29 Akim Demaille <akim@epita.fr>
667
668 Don't store the token defs in a muscle, just be ready to output it
669 on command. Now possible via `symbols'. Fixes a memory leak.
670
671 * src/output.c (token_definitions_output): New.
672 (output_parser, header_output): Use it.
673 * src/reader.c (symbols_save): Remove.
674
675 2001-12-29 Akim Demaille <akim@epita.fr>
676
677 * src/bison.simple: Do not provide a default for YYSTYPE and
678 YYLTYPE before the user's prologue. Otherwise it's hardly... a
679 default.
680
681 2001-12-29 Akim Demaille <akim@epita.fr>
682
683 Mid-rule actions are simply... ignored!
684
685 * src/reader.c (readgram): Be sure to attach mid-rule actions to
686 the empty-rule associated to the dummy symbol, not to the host
687 rule.
688 * tests/actions.at (Mid-rule actions): New.
689
690 2001-12-29 Akim Demaille <akim@epita.fr>
691
692 Memory leak.
693
694 * src/reader.c (reader): Free grammar.
695
696 2001-12-29 Akim Demaille <akim@epita.fr>
697
698 Memory leak.
699
700 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
701 since it allocates it for each state, although only one is needed.
702 (allocate_storage): Do it here.
703
704 2001-12-29 Akim Demaille <akim@epita.fr>
705
706 * src/options.h, src/options.c (create_long_option_table): Rename
707 as...
708 (long_option_table_new): this, with a clearer prototype.
709 (percent_table): Remove, unused,
710 * src/getargs.c (getargs): Adjust.
711
712 2001-12-29 Akim Demaille <akim@epita.fr>
713
714 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
715 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
716 as states.
717
718 2001-12-29 Akim Demaille <akim@epita.fr>
719
720 * src/lalr.c (build_relations): Rename `states' as `states1'.
721 Sorry, I don't understand exactly what it is, no better name...
722
723 2001-12-29 Akim Demaille <akim@epita.fr>
724
725 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
726 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
727 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
728 as rules.
729
730 2001-12-29 Akim Demaille <akim@epita.fr>
731
732 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
733 ago.
734
735 2001-12-29 Akim Demaille <akim@epita.fr>
736
737 * src/reader.c, src/reader.h (user_toknums): Remove.
738 Adjust all users to use symbols[i]->user_token_number.
739
740 2001-12-29 Akim Demaille <akim@epita.fr>
741
742 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
743 Adjust all users to use symbols[i]->prec or ->assoc.
744
745 2001-12-29 Akim Demaille <akim@epita.fr>
746
747 * src/reader.c, src/reader.h (tags): Remove.
748 Adjust all users to use symbols[i]->tag.
749
750 2001-12-29 Akim Demaille <akim@epita.fr>
751
752 * src/gram.h, src/gram.c (symbols): New, similar to state_table
753 and rule_table.
754 * src/reader.c (packsymbols): Fill this table.
755 Drop sprec.
756 * src/conflicts.c (resolve_sr_conflict): Adjust.
757 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
758 single table.
759 Use symbols[i]->tag instead of tags[i].
760
761 2001-12-29 Akim Demaille <akim@epita.fr>
762
763 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
764 In addition, put a comment in there, to replace...
765 * tests/regression.at (%union and C comments): Remove.
766
767 2001-12-29 Akim Demaille <akim@epita.fr>
768
769 * tests/regression.at (Web2c Actions): Blindly move the actual
770 output as expected output. The contents *seem* right to me, but I
771 can't pretend reading perfectly parser tables... Nonetheless, all
772 the other tests pass correctly, the table look OK, even though the
773 presence of `$axiom' is to be noted: AFAICS it is useless (but
774 harmless).
775
776 2001-12-29 Akim Demaille <akim@epita.fr>
777
778 * src/reader.c (readgram): Don't add the rule 0 if there were no
779 rules read. In other words, add it _after_ having performed
780 grammar sanity checks.
781 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
782
783 2001-12-29 Akim Demaille <akim@epita.fr>
784
785 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
786 visible, and some states have now a different number.
787
788 2001-12-29 Akim Demaille <akim@epita.fr>
789
790 * src/reader.c (readgram): Bind the initial rule's lineno to that
791 of the first rule.
792 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
793 (Solved SR Conflicts): Adjust rule 0's line number.
794
795 2001-12-29 Akim Demaille <akim@epita.fr>
796
797 Fix the `GAWK Grammar' failure.
798
799 * src/LR0.c (final_state): Initialize to -1 so that we do compute
800 the reductions of the first state which was mistakenly confused
801 with the final state because precisely final_state was initialized
802 to 0.
803 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
804 now noticed by Bison.
805 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
806 have a reduction on $default.
807
808 2001-12-29 Akim Demaille <akim@epita.fr>
809
810 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
811 rule line numbers.
812 * src/closure.c (print_closure): Likewise.
813 * src/derives.c (print_derives): Likewise.
814 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
815 now.
816
817 2001-12-29 Akim Demaille <akim@epita.fr>
818
819 * src/lalr.c (lookaheads_print): New.
820 (lalr): Call it when --trace-flag.
821 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
822 are dumped.
823
824 2001-12-29 Akim Demaille <akim@epita.fr>
825
826 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
827 when walking through ritem, even via rule->rhs.
828 * src/reduce.c (dump_grammar, useful_production, reduce_output)
829 (useful_production, useless_nonterminals): Likewise.
830 (reduce_grammar_tables): Likewise, plus update nritems.
831 * src/nullable.c (set_nullable): Likewise.
832 * src/lalr.c (build_relations): Likewise.
833 * tests/sets.at (Nullable): Adjust.
834 Fortunately, now, the $axiom is no longer nullable.
835
836 2001-12-29 Akim Demaille <akim@epita.fr>
837
838 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
839 the 0-sentinel.
840 * src/gram.c (ritem_longest_rhs): Likewise.
841 * src/reduce.c (nonterminals_reduce): Likewise.
842 * src/print_graph.c (print_graph): Likewise.
843 * src/output.c (output_rule_data): Likewise.
844 * src/nullable.c (set_nullable): Likewise.
845
846 2001-12-29 Akim Demaille <akim@epita.fr>
847
848 * src/output.c: Comment changes.
849
850 2001-12-27 Paul Eggert <eggert@twinsun.com>
851
852 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
853 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
854 Sparc, as they were causing more porting problems than the
855 (minor) performance improvement was worth.
856
857 Also, catch up with 1.31's YYSTD.
858
859 2001-12-27 Akim Demaille <akim@epita.fr>
860
861 * src/output.c (output_gram): Rely on nritems, not the
862 0-sentinel. See below.
863 Use -1 as separator, not 0.
864 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
865 Rely on -1 as separator in yyrhs, instead of 0.
866 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
867 twice `Now at end of input', therefore there are two lines less to
868 expect.
869
870 2001-12-27 Akim Demaille <akim@epita.fr>
871
872 * tests/regression.at (Unresolved SR Conflicts):
873 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
874 below.
875
876 2001-12-27 Akim Demaille <akim@epita.fr>
877
878 * src/LR0.c (new_state): Recognize the final state by the fact it
879 is reached by eoftoken.
880 (insert_start_shifting_state, insert_eof_shifting_state)
881 (insert_accepting_state, augment_automaton): Remove, since now
882 these states are automatically computed from the initial state.
883 (generate_states): Adjust.
884 * src/print.c: When reporting a rule number to the user, substract
885 1, so that the axiom rule is rule 0, and the first user rule is 1.
886 * src/reduce.c: Likewise.
887 * src/print_graph.c (print_core): For the time being, just as for
888 the report, depend upon --trace-flags to dump the full set of
889 items.
890 * src/reader.c (readgram): Once the grammar read, insert the rule
891 0: `$axiom: START-SYMBOL $'.
892 * tests/set.at: Adjust: rule 0 is now displayed, and since the
893 number of the states has changed (the final state is no longer
894 necessarily the last), catch up.
895
896 2001-12-27 Akim Demaille <akim@epita.fr>
897
898 Try to make the use of the eoftoken valid. Given that its value
899 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
900 is used instead of > 0 where appropriate, (ii), depend upon nritems
901 instead of the 0-sentinel.
902
903 * src/gram.h, src/gram.c (nritems): New.
904 Expected to be duplication of nitems, but for the time being...
905 * src/reader.c (packgram): Assert nritems and nitems are equal.
906 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
907 * src/closure.c (print_closure, print_fderives): Likewise.
908 * src/gram.c (ritem_print): Likewise.
909 * src/print.c (print_core, print_grammar): Likewise.
910 * src/print_graph.c: Likewise.
911
912 2001-12-27 Akim Demaille <akim@epita.fr>
913
914 * src/main.c (main): If there are complains after grammar
915 reductions, then output the report anyway if requested, then die.
916 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
917 * src/reader.c (eoftoken): New.
918 (parse_token_decl): If the token being defined has value `0', it
919 is the eoftoken.
920 (packsymbols): No longer hack `tags' to insert `$' by hand.
921 Be sure to preserve the value of the eoftoken.
922 (reader): Make sure eoftoken is defined.
923 Initialize nsyms to 0: now eoftoken is created just like the others.
924 * src/print.c (print_grammar): Don't special case the eof token.
925 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
926 lie anyway, albeit pleasant.
927 * tests/calc.at: Exercise error messages with eoftoken.
928 Change the grammar so that empty input is invalid.
929 Adjust expectations.
930 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
931
932 2001-12-27 Akim Demaille <akim@epita.fr>
933
934 * configure.in: Check the protos of strchr ans strspn.
935 Replace strchr if needed.
936 * src/system.h: Provide the protos of strchr, strspn and memchr if
937 missing.
938 * lib/strchr.c: New.
939 * src/reader.c (symbols_save): Use strchr.
940
941 2001-12-27 Akim Demaille <akim@epita.fr>
942
943 * src/print.c, src/print_graph.c (escape): New.
944 Use it to quote the TAGS outputs.
945 * src/print_graph.c (print_state): Now errors are in red, and
946 reductions in green.
947 Prefer high to wide: output the state number on a line of its own.
948
949 2001-12-27 Akim Demaille <akim@epita.fr>
950
951 * src/state.h, src/state.c (reductions_new): New.
952 * src/LR0.c (set_state_table): Let all the states have a
953 `reductions', even if reduced to 0.
954 (save_reductions): Adjust.
955 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
956 * src/print.c (print_reductions, print_actions): Adjust.
957 * src/output.c (action_row): Adjust.
958
959 2001-12-27 Akim Demaille <akim@epita.fr>
960
961 * src/state.h, src/state.c (errs_new, errs_dup): New.
962 * src/LR0.c (set_state_table): Let all the states have an errs,
963 even if reduced to 0.
964 * src/print.c (print_errs, print_reductions): Adjust.
965 * src/output.c (output_actions, action_row): Adjust.
966 * src/conflicts.c (resolve_sr_conflict): Adjust.
967
968 2001-12-27 Akim Demaille <akim@epita.fr>
969
970 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
971
972 2001-12-27 Akim Demaille <akim@epita.fr>
973
974 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
975 * src/print.c: here.
976 (lookaheadset, shiftset): New, used as additional storage by
977 print_reductions.
978 (print_results): Adjust.
979 (print_shifts, print_gotos, print_errs): New, extracted from...
980 (print_actions): here.
981 * src/print_graph.c (print_actions): Remove dead code.
982
983 2001-12-27 Akim Demaille <akim@epita.fr>
984
985 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
986 `$n' and `@n'.
987
988 2001-12-27 Akim Demaille <akim@epita.fr>
989
990 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
991 (build_relations): Adjust.
992
993 2001-12-27 Akim Demaille <akim@epita.fr>
994
995 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
996 duplication.
997
998 2001-12-27 Akim Demaille <akim@epita.fr>
999
1000 * src/reader.c (packgram): Catch nitems overflows.
1001
1002 2001-12-27 Akim Demaille <akim@epita.fr>
1003
1004 * src/files.c, src/files.h (guard_obstack): Remove.
1005 * src/output.c (output): Adjust.
1006 * src/reader.c (parse_braces): New, factoring...
1007 (copy_action, copy_guard): these two which are renamed as...
1008 (parse_action, parse_guard): these.
1009 As a voluntary consequence, using braces around guards is now
1010 mandatory.
1011
1012 2001-12-27 Akim Demaille <akim@epita.fr>
1013
1014 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
1015 * src/reader.c (symbol_list): `guard' and `guard_line' are new
1016 members.
1017 (symbol_list_new): Adjust.
1018 (copy_action): action_line is the first line, not the last.
1019 (copy_guard): Just as for actions, store the `action' only, not
1020 the switch/case/break flesh.
1021 Don't parse the user action that might follow the guard, let...
1022 (readgram): do it, i.e., now, there can be an action after a
1023 guard.
1024 In other words the guard is just explicitly optional.
1025 (packgram): Adjust.
1026 * src/output.c (guards_output): New.
1027 (output_parser): Call it when needed.
1028 (output): Also free the guard and attrs obstacks.
1029 * src/files.c, src/files.h (obstack_save): Remove.
1030 (output_files): Remove.
1031 As a result, if one needs the former `.act' file, using an
1032 appropriate skeleton which requires actions and guards is now
1033 required.
1034 * src/main.c (main): Adjust.
1035 * tests/semantic.at: New.
1036 * tests/regression.at: Use `input.y' as input file name.
1037 Avoid 8+3 problems by requiring input.c when the test needs the
1038 parser.
1039
1040 2001-12-27 Akim Demaille <akim@epita.fr>
1041
1042 * src/reader.c (symbol_list_new): Be sure to initialize all the
1043 fields.
1044
1045 2001-12-27 Akim Demaille <akim@epita.fr>
1046
1047 All the hacks using a final pseudo state are now useless.
1048
1049 * src/LR0.c (set_state_table): state_table holds exactly nstates.
1050 * src/lalr.c (nLA): New.
1051 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1052 instead of lookaheadsp from the pseudo state (nstate + 1).
1053
1054 2001-12-27 Akim Demaille <akim@epita.fr>
1055
1056 * src/output.c (action_row, token_actions): Use a state_t instead
1057 of a integer, and nlookaheads instead of the following state's
1058 lookaheadsp.
1059
1060 2001-12-27 Akim Demaille <akim@epita.fr>
1061
1062 * src/conflicts.c (log_resolution, flush_shift)
1063 (resolve_sr_conflict, set_conflicts, solve_conflicts)
1064 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1065 (conflicts_print, print_reductions): Use a state_t instead of an
1066 integer when referring to a state.
1067 As much as possible, depend upon nlookaheads, instead of the
1068 `lookaheadsp' member of the following state (since lookaheads of
1069 successive states are successive, the difference between state n + 1
1070 and n served as the number of lookaheads for state n).
1071 * src/lalr.c (add_lookback_edge): Likewise.
1072 * src/print.c (print_core, print_actions, print_state)
1073 (print_results): Likewise.
1074 * src/print_graph.c (print_core, print_actions, print_state)
1075 (print_graph): Likewise.
1076 * src/conflicts.h: Adjust.
1077
1078 2001-12-27 Akim Demaille <akim@epita.fr>
1079
1080 * src/bison.hairy: Formatting/comment changes.
1081 ANSIfy.
1082 Remove `register' indications.
1083 Add plenty of `static'.
1084
1085 2001-12-27 Akim Demaille <akim@epita.fr>
1086
1087 * src/output.c (prepare): Drop the muscle `ntbase' which
1088 duplicates ntokens.
1089 * src/bison.simple: Formatting/comment changes.
1090 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1091 is an undocumented synonym.
1092
1093 2001-12-22 Akim Demaille <akim@epita.fr>
1094
1095 * src/output.c (output_table_data): Change the prototype to use
1096 `int' for array ranges: some invocations do pass an int, not a
1097 short.
1098 Reported by Wayne Green.
1099
1100 2001-12-22 Akim Demaille <akim@epita.fr>
1101
1102 Some actions of web2c.y are improperly triggered.
1103 Reported by Mike Castle.
1104
1105 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1106 * tests/regression.at (Web2c): Rename as...
1107 (Web2c Report): this.
1108 (Web2c Actions): New.
1109
1110 2001-12-22 Akim Demaille <akim@epita.fr>
1111
1112 Reductions in web2c.y are improperly reported.
1113 Reported by Mike Castle.
1114
1115 * src/conflicts.c (print_reductions): Fix.
1116 * tests/regression.at (Web2c): New.
1117
1118 2001-12-18 Akim Demaille <akim@epita.fr>
1119
1120 Some host fail on `assert (!"foo")', which expands to
1121 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1122 Reported by Nelson Beebee.
1123
1124 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1125 `#define it_succeeded 0' and `assert (it_succeeded)'.
1126
1127 2001-12-17 Marc Autret <autret_m@epita.fr>
1128
1129 * src/bison.simple: Don't hard code the skeleton line and filename.
1130 * src/output.c (output_parser): Rename 'line' as 'output_line'.
1131 New line counter 'skeleton_line' (skeleton-line muscle).
1132
1133 2001-12-17 Paul Eggert <eggert@twinsun.com>
1134
1135 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1136 YYDEBUG must be defined to a nonzero value.
1137
1138 * src/bison.simple (yytname): Do not assume that the user defines
1139 YYDEBUG to a properly parenthesized expression.
1140
1141 2001-12-17 Akim Demaille <akim@epita.fr>
1142
1143 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1144 nlookaheads is a new member.
1145 Adjust all users.
1146 * src/lalr.h (nlookaheads): Remove this orphan declaration.
1147 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
1148 state.
1149
1150 2001-12-17 Akim Demaille <akim@epita.fr>
1151
1152 * src/files.h, src/files.c (open_files, close_files): Remove.
1153 * src/main.c (main): Don't open/close files, nor invoke lex_free,
1154 let...
1155 * src/reader.c (reader): Do it.
1156
1157 2001-12-17 Akim Demaille <akim@epita.fr>
1158
1159 * src/conflicts.c (print_reductions): Formatting changes.
1160
1161 2001-12-17 Akim Demaille <akim@epita.fr>
1162
1163 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1164 (flush_reduce): New.
1165 (resolve_sr_conflict): Adjust.
1166
1167 2001-12-17 Akim Demaille <akim@epita.fr>
1168
1169 * src/output.c (output_obstack): Be static and rename as...
1170 (format_obstack): this, to avoid any confusion with files.c's
1171 output_obstack.
1172 * src/reader.h (muscle_obstack): Move to...
1173 * src/output.h: here, since it's defined in output.c.
1174
1175 2001-12-17 Akim Demaille <akim@epita.fr>
1176
1177 * src/output.c (action_row, save_column, default_goto)
1178 (sort_actions, matching_state, pack_vector): Better variable
1179 locality.
1180
1181 2001-12-17 Akim Demaille <akim@epita.fr>
1182
1183 * src/output.c: Various formatting changes.
1184
1185 2001-12-17 Akim Demaille <akim@epita.fr>
1186
1187 * src/files.c (output_files): Free the output_obstack.
1188 * src/main.c (main): Call print and print_graph conditionally.
1189 * src/print.c (print): Work unconditionally.
1190 * src/print_graph.c (print_graph): Work unconditionally.
1191 * src/conflicts.c (log_resolution): Output only if verbose_flag.
1192
1193 2001-12-16 Marc Autret <autret_m@epita.fr>
1194
1195 * src/output.c (actions_output): Fix. When we use %no-lines,
1196 there is one less line per action.
1197
1198 2001-12-16 Marc Autret <autret_m@epita.fr>
1199
1200 * src/bison.simple: Remove a useless #line directive.
1201 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1202 * src/output.c (get_lines_number): New.
1203 (output_parser): Adjust, now takes care about the lines of a
1204 output muscles.
1205 Fix line numbering.
1206 (actions_output): Computes the number of lines taken by actions.
1207 (output_master_parser): Insert new skeleton which is the name of
1208 the output parser file name.
1209
1210 2001-12-15 Marc Autret <autret_m@epita.fr>
1211
1212 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1213
1214 2001-12-15 Marc Autret <autret_m@epita.fr>
1215
1216 * src/output.c (output_gram): Keep track of the hairy one.
1217
1218 2001-12-15 Akim Demaille <akim@epita.fr>
1219
1220 Make `make distcheck' work.
1221
1222 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1223 system.h which uses libgettext.h.
1224
1225 2001-12-15 Akim Demaille <akim@epita.fr>
1226
1227 * src/nullable.c (set_nullable): Useless rules must be skipped,
1228 otherwise, since we range over their symbols, we might look at a
1229 nonterminal which no longer ``exists'', i.e., it is not counted in
1230 `nvars', hence we overflow our arrays.
1231
1232 2001-12-15 Akim Demaille <akim@epita.fr>
1233
1234 The header can also be produced directly, without any obstack!
1235 Yahoo!
1236
1237 * src/files.c, src/files.h (defines_obstack): Remove.
1238 (compute_header_macro): Global.
1239 (defines_obstack_save): Remove.
1240 * src/reader.c (parse_union_decl): No longer output to
1241 defines_obstack: its content can be found in the `stype' muscle
1242 anyway.
1243 (output_token_translations): Merge into...
1244 (symbols_output): this.
1245 Rename as...
1246 (symbols_save): this.
1247 (reader): Adjust.
1248 * src/output.c (header_output): New.
1249 (output): Call it.
1250
1251 2001-12-15 Akim Demaille <akim@epita.fr>
1252
1253 * src/reader.c (parse_union_decl): Instead of handling two obstack
1254 simultaneously, use one to define the `stype' muscle, and use the
1255 value of the latter to fill defines_obstack.
1256 (copy_comment): Remove.
1257 (copy_comment2): Work for a single obstack.
1258 Rename as...
1259 (copy_comment): this.
1260
1261 2001-12-15 Akim Demaille <akim@epita.fr>
1262
1263 * src/lex.c, src/lex.h (xgetc): No longer static.
1264 * src/reader.c (parse_union_decl): Revamp.
1265
1266 2001-12-15 Akim Demaille <akim@epita.fr>
1267
1268 Still making progress in separating Bison into (i) input, (ii)
1269 process, (iii) output: now we can directly output the parser file
1270 without using table_obstack at all.
1271
1272 * src/files.c, src/files.h (table_obstack): Bye bye.
1273 (parser_file_name): New.
1274 * src/files.c (compute_output_file_names): Compute it.
1275 * src/output.c (actions_output, output_parser)
1276 (output_master_parser): To a file instead of an obstack.
1277
1278 2001-12-15 Akim Demaille <akim@epita.fr>
1279
1280 Attach actions to rules, instead of pre-outputting them to
1281 actions_obstack.
1282
1283 * src/gram.h (rule_t): action and action_line are new members.
1284 * src/reader.c (symbol_list): Likewise.
1285 (copy_action): Save the actions within the rule.
1286 (packgram): Save them in rule_table.
1287 * src/output.c (actions_output): New.
1288 (output_parser): Use it on `%%actions'.
1289 (output_rule_data): Don't free rule_table.
1290 (output): Do it.
1291 (prepare): Don't save the `action' muscle.
1292 * src/bison.simple: s/%%action/%%actions/.
1293
1294 2001-12-15 Akim Demaille <akim@epita.fr>
1295
1296 * src/reader.c (copy_action): When --yacc, don't append a `;'
1297 to the user action: let it fail if lacking.
1298 Suggested by Arnold Robbins and Tom Tromey.
1299
1300 2001-12-14 Akim Demaille <akim@epita.fr>
1301
1302 * src/lex.c (literalchar): Simply return the char you decoded, non
1303 longer mess around with obstacks and int pointers.
1304 Adjust all callers.
1305
1306 2001-12-14 Akim Demaille <akim@epita.fr>
1307
1308 * src/lex.c (literalchar): Don't escape the special characters,
1309 just decode them, and keep them as char (before, eol was output as
1310 the 2 char string `\n' etc.).
1311 * src/output.c (output_rule_data): Use quotearg to output the
1312 token strings.
1313
1314 2001-12-13 Paul Eggert <eggert@twinsun.com>
1315
1316 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1317 Do not infringe on the global user namespace when using C++.
1318 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1319 All uses of `fprintf' and `stderr' changed.
1320
1321 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1322
1323 2001-12-13 Akim Demaille <akim@epita.fr>
1324
1325 The computation of nullable is broken: it doesn't handle empty
1326 RHS's properly.
1327
1328 * tests/torture.at (GNU AWK Grammar): New.
1329 * tests/sets.at (Nullable): New.
1330 * src/nullable.c (set_nullable): Instead of blindly looping over
1331 `ritems', loop over the rules, and then over their rhs's.
1332
1333 Work around Autotest bugs.
1334
1335 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1336 frame, because Autotest understand lines starting with a `+' as
1337 traces from the shell. Then, they are not processed properly.
1338 Admittedly an Autotest bug, but we don't have time to wait for
1339 Autotest to catch up.
1340 * tests/regression.at (Broken Closure): Adjust to the new table
1341 frames.
1342 Move to...
1343 * tests/sets.at: here.
1344
1345 2001-12-13 Akim Demaille <akim@epita.fr>
1346
1347 * src/closure.c (closure): Use nrules instead of playing tricks
1348 with BITS_PER_WORD.
1349
1350 2001-12-13 Akim Demaille <akim@epita.fr>
1351
1352 * src/print.c (print_actions): Output the handling of `$' as the
1353 traces do: shifting the token EOF. Before EOF was treated as a
1354 nonterminal.
1355 * tests/regression.at: Adjust some tests.
1356 * src/print_graph.c (print_core): Complete the set of items via
1357 closure. The next-to-final and final states are still unsatisfying,
1358 but that's to be addressed elsewhere.
1359 No longer output the rule numbers, but do output the state number.
1360 A single loop for the shifts + gotos is enough, but picked a
1361 distinct color for each.
1362 (print_graph): Initialize and finalize closure.
1363
1364 2001-12-13 Akim Demaille <akim@epita.fr>
1365
1366 * src/reader.c (readgram): Remove dead code, an strip useless
1367 braces.
1368 (get_type): Remove, unused.
1369
1370 2001-12-12 Akim Demaille <akim@epita.fr>
1371
1372 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1373 on that of lib/error.c.
1374
1375 2001-12-12 Akim Demaille <akim@epita.fr>
1376
1377 Some hosts don't like `/' in includes.
1378
1379 * src/system.h: Include libgettext.h without qualifying the path.
1380 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1381 $(top_srcdir).
1382
1383 2001-12-11 Marc Autret <autret_m@epita.fr>
1384
1385 * src/output.c (output_parser): Remove useless muscle.
1386
1387 2001-12-11 Marc Autret <autret_m@epita.fr>
1388
1389 * src/bison.simple: Remove #line just before %%epilogue. It
1390 is now handled in ...
1391 * src/reader.c (read_additionnal_code): Add the output of a
1392 #line for the epilogue.
1393
1394 2001-12-10 Marc Autret <autret_m@epita.fr>
1395
1396 * src/reader.c (copy_definition): Re-use CPP-outed code which
1397 replace precedent remove.
1398 * src/bison.simple: Remove #line before %%prologue because
1399 %%input-line is wrong at this time.
1400
1401 2001-12-10 Marc Autret <autret_m@epita.fr>
1402
1403 * src/reader.c (symbols_output): Clean up.
1404 * src/output.c (output_gram, output): Clean up.
1405
1406 2001-12-10 Akim Demaille <akim@epita.fr>
1407
1408 * src/lalr.c (initialize_lookaheads): New. Extracted from...
1409 * src/LR0.c (set_state_table): here.
1410 * src/lalr.c (lalr): Call it.
1411
1412 2001-12-10 Akim Demaille <akim@epita.fr>
1413
1414 * src/state.h (shifts): Remove the `number' member: shifts are
1415 attached to state, hence no longer need to be labelled with a
1416 state number.
1417
1418 2001-12-10 Akim Demaille <akim@epita.fr>
1419
1420 Now that states have a complete set of members, the linked list of
1421 shifts is useless: just fill directly the state's shifts member.
1422
1423 * src/state.h (shifts): Remove the `next' member.
1424 * src/LR0.c (first_state, last_state): Remove.
1425 Adjust the callers.
1426 (augment_automaton): Don't look for the shifts that must be added
1427 a shift on EOF: it is those of the state we looked for! But now,
1428 since shifts are attached, it is no longer needed to looking
1429 merely by its id: its number.
1430
1431 2001-12-10 Akim Demaille <akim@epita.fr>
1432
1433 * src/LR0.c (augment_automaton): Better variable locality.
1434 Remove an impossible branch: if there is a state corresponding to
1435 the start symbol being shifted, then there is shift for the start
1436 symbol from the initial state.
1437
1438 2001-12-10 Akim Demaille <akim@epita.fr>
1439
1440 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1441 only when appropriate: when insert_start_shifting_state' is not
1442 invoked.
1443 * tests/regression.at (Rule Line Numbers): Adjust.
1444
1445 2001-12-10 Akim Demaille <akim@epita.fr>
1446
1447 * src/LR0.c (augment_automaton): Now that all states have shifts,
1448 merge the two cases addition shifts to the initial state.
1449
1450 2001-12-10 Akim Demaille <akim@epita.fr>
1451
1452 * src/lalr.c (set_state_table): Move to...
1453 * src/LR0.c: here.
1454 * src/lalr.c (lalr): Don't call it...
1455 * src/LR0.c (generate_states): do it.
1456 * src/LR0.h (first_state): Remove, only the table is used.
1457
1458 2001-12-10 Akim Demaille <akim@epita.fr>
1459
1460 * src/LR0.h (first_shift, first_reduction): Remove.
1461 * src/lalr.c: Don't use first_shift: find shifts through the
1462 states.
1463
1464 2001-12-10 Akim Demaille <akim@epita.fr>
1465
1466 * src/LR0.c: Attach shifts to states as soon as they are
1467 computed.
1468 * src/lalr.c (set_state_table): Instead of assigning shifts to
1469 state, just assert that the mapping was properly done.
1470
1471 2001-12-10 Akim Demaille <akim@epita.fr>
1472
1473 * src/LR0.c (insert_start_shift): Rename as...
1474 (insert_start_shifting_state): this.
1475 (insert_eof_shifting_state, insert_accepting_state): New.
1476 (augment_automaton): Adjust.
1477 Better locality of the variables.
1478 When looking if the start_symbol is shifted from the initial
1479 state, using `while (... symbol != start_symbol ...)' sounds
1480 better than `while (... symbol < start_symbol ...)': If fail
1481 to see how the order between symbols could be relevant!
1482
1483 2001-12-10 Akim Demaille <akim@epita.fr>
1484
1485 * src/getargs.h: Don't declare `spec_name_prefix' and
1486 `spec_file_prefix', declared by src/files.h.
1487 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1488 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1489 * src/output.c (prepare): Adjust.
1490 * src/reader.c (symbols_output): Likewise.
1491 * src/vmsgetargs.c: Vaguely adjust, but who cares?
1492
1493 2001-12-10 Akim Demaille <akim@epita.fr>
1494
1495 * src/muscle_tab.c (muscle_init): NULL is a better default than
1496 `"0"'.
1497
1498 2001-12-10 Akim Demaille <akim@epita.fr>
1499
1500 * src/reader.c (reader): Calling symbols_output once is enough.
1501
1502 2001-12-10 Akim Demaille <akim@epita.fr>
1503
1504 Now that states have a complete set of members, the linked list of
1505 reductions is useless: just fill directly the state's reductions
1506 member.
1507
1508 * src/state.h (struct reductions): Remove member `number' and
1509 `next'.
1510 * src/LR0.c (first_reduction, last_reduction): Remove.
1511 (save_reductions): Don't link the new reductions, store them in
1512 this_state.
1513 * src/lalr.c (set_state_table): No need to attach reductions to
1514 states, it's already done.
1515 * src/output.c (output_actions): No longer free the shifts, then
1516 the reductions, then the states: free all the states and their
1517 members.
1518
1519 2001-12-10 Akim Demaille <akim@epita.fr>
1520
1521 * src/options.c (OPTN, DRTV, BOTH): New.
1522 (option_table): Use them.
1523
1524 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1525 the job of system.h.
1526 * src/options.c: Don't include stdio.h and xalloc.h for the same
1527 reasons.
1528
1529 2001-12-10 Akim Demaille <akim@epita.fr>
1530
1531 * src/output.c (output, prepare): Make sure the values of the
1532 muscles `action' and `prologue' are 0-terminated.
1533
1534 2001-12-10 Akim Demaille <akim@epita.fr>
1535
1536 Clean up GCC warnings.
1537
1538 * src/reader.c (copy_action): `buf' is not used.
1539 (parse_skel_decl): Be static.
1540 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1541 * src/options.h (create_long_option_table): Have a real prototype.
1542 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1543 (hash_delete_at): Return const void *.
1544 Adjust casts to preserve the const.
1545
1546 2001-12-10 Akim Demaille <akim@epita.fr>
1547
1548 * configure.in: Require 2.52g.
1549 M4 is not needed, but AUTOM4TE is.
1550 * m4/m4.m4: Remove.
1551 * tests/Makefile.am: Adjust.
1552
1553 2001-12-10 Akim Demaille <akim@epita.fr>
1554
1555 One structure for states is enough, even though theoretically
1556 there are LR(0) states and LALR(1) states.
1557
1558 * src/lalr.h (state_t): Remove.
1559 (state_table): Be state_t **, not state_t *.
1560 * src/state.h (core, CORE_ALLOC): Rename as...
1561 (state_t, STATE_ALLOC): this.
1562 Add the LALR(1) members: shifts, reductions, errs.
1563 * src/LR0.c (state_table): Rename as...
1564 (state_hash): this, to avoid name clashes with the global
1565 `state_table'.
1566 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1567 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1568
1569 2001-12-10 Akim Demaille <akim@epita.fr>
1570
1571 Bison dumps core on bash.y.
1572 Reported by Pascal Bart.
1573
1574 * src/warshall.c (bitmatrix_print): New.
1575 (TC): Use it.
1576 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1577 j must be the outer loop.
1578 * tests/regression.at (Broken Closure): New.
1579
1580 2001-12-05 Akim Demaille <akim@epita.fr>
1581
1582 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1583 its argument.
1584 Reported by Peter Hámorský.
1585
1586 2001-12-05 Akim Demaille <akim@epita.fr>
1587
1588 * src/conflicts.c (err_table): Remove.
1589 (resolve_sr_conflict): Adjust.
1590 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1591 Rename as...
1592 (state_t.reductions, state_t.shifts): this.
1593
1594 2001-12-05 Akim Demaille <akim@epita.fr>
1595
1596 * src/reduce.c (reduce_grammar_tables): No longer disable the
1597 removal of useless rules via CPP but via `if (0)', so that the
1598 compiler still check the code is valid.
1599 For instance, it should have noticed `rline' no longer exists: use
1600 the `line' member of rule_t.
1601 * src/gram.c (dummy, rline): Remove, unused.
1602
1603 2001-12-05 Akim Demaille <akim@epita.fr>
1604
1605 * src/output.c (pack_vector): Use assert, not berror.
1606 * src/main.c (berror): Remove, unused.
1607
1608 2001-12-05 Akim Demaille <akim@epita.fr>
1609
1610 New experimental feature: if --verbose --trace output all the
1611 items of a state, not only its kernel.
1612
1613 * src/print.c (print_core): If `trace_flag', then invoke closure
1614 before outputting the items of the state (print_core is no longer
1615 a correct name them).
1616 (print_results): Invoke new_closure/free_closure if needed.
1617
1618 2001-12-05 Akim Demaille <akim@epita.fr>
1619
1620 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1621 * src/closure.c, src/closure.h (itemsetsize): Rename as...
1622 (nitemset): for consistency with the rest of the project.
1623
1624 2001-12-05 Akim Demaille <akim@epita.fr>
1625
1626 * src/closure.c (print_closure): Improve.
1627 (closure): Use it for printing input and output.
1628
1629 2001-12-05 Akim Demaille <akim@epita.fr>
1630
1631 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1632 indexed by nonterminals.
1633
1634 2001-12-05 Akim Demaille <akim@epita.fr>
1635
1636 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1637 what it was!).
1638 * src/warshall.h: Remove accidental duplication of the content.
1639
1640 2001-12-05 Akim Demaille <akim@epita.fr>
1641
1642 * src/closure.c (set_fderives): De-obfuscate.
1643
1644 2001-12-05 Akim Demaille <akim@epita.fr>
1645
1646 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
1647
1648 2001-12-05 Akim Demaille <akim@epita.fr>
1649
1650 * src/closure.c (set_firsts): De-obfuscate.
1651
1652 2001-12-05 Akim Demaille <akim@epita.fr>
1653
1654 * src/output.c (action_row): De-obfuscate
1655 using the good o' techniques: arrays not pointers, variable
1656 locality, BITISSET, RESETBIT etc.
1657
1658 2001-12-05 Akim Demaille <akim@epita.fr>
1659
1660 Pessimize the code to simplify it: from now on, all the states
1661 have a valid SHIFTS, which NSHIFTS is possibly 0.
1662
1663 * src/LR0.c (shifts_new): Be global and move to..
1664 * src/state.c, src/state.h: here.
1665 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1666 * src/print_graph: Adjust.
1667
1668 2001-12-05 Akim Demaille <akim@epita.fr>
1669
1670 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1671 * src/conflicts.c: Use it.
1672 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1673 incorrectly ``simplified''.
1674
1675 2001-12-05 Akim Demaille <akim@epita.fr>
1676
1677 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1678 using the good o' techniques: arrays not pointers, variable
1679 locality, BITISSET, RESETBIT etc.
1680
1681 2001-12-05 Akim Demaille <akim@epita.fr>
1682
1683 * src/state.h (SHIFT_SYMBOL): New.
1684 * src/conflicts.c: Use it to deobfuscate.
1685
1686 2001-12-05 Akim Demaille <akim@epita.fr>
1687
1688 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1689 (print_reductions): De-obfuscate using the good o' techniques:
1690 arrays not pointers, variable locality, BITISSET.
1691
1692 2001-12-05 Akim Demaille <akim@epita.fr>
1693
1694 * src/conflicts.c (print_reductions): Arrays, not pointers.
1695 Use BITISSET.
1696
1697 2001-12-05 Akim Demaille <akim@epita.fr>
1698
1699 * src/conflicts.c (print_reductions): Pessimize, but clarify.
1700
1701 2001-12-05 Akim Demaille <akim@epita.fr>
1702
1703 * src/conflicts.c (print_reductions): Improve variable locality.
1704
1705 2001-12-05 Akim Demaille <akim@epita.fr>
1706
1707 * src/conflicts.c (print_reductions): Pessimize, but clarify.
1708
1709 2001-12-05 Akim Demaille <akim@epita.fr>
1710
1711 * src/conflicts.c (print_reductions): Improve variable locality.
1712
1713 2001-12-05 Akim Demaille <akim@epita.fr>
1714
1715 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1716 * src/lalr.c: Use them.
1717
1718 2001-12-05 Akim Demaille <akim@epita.fr>
1719
1720 * src/LR0.c (augment_automaton): Formatting changes.
1721 Better variable locality.
1722
1723 2001-12-05 Akim Demaille <akim@epita.fr>
1724
1725 * src/lalr.c (matrix_print): New.
1726 (transpose): Use it.
1727 Use arrays instead of pointers.
1728
1729 2001-12-05 Akim Demaille <akim@epita.fr>
1730
1731 * src/lalr.c (maxrhs): Move to...
1732 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1733 * src/lalr.c (build_relations): Adjust.
1734
1735 2001-12-05 Akim Demaille <akim@epita.fr>
1736
1737 * src/lalr.c (transpose): Free the memory allocated to the
1738 argument, as it is replaced by the results by the unique caller.
1739 (build_relations): Merely invoke transpose: it handles the memory
1740 deallocation.
1741 Improve variable locality.
1742 Avoid variables used as mere abbreviations.
1743 (compute_lookaheads): Use arrays instead of pointers.
1744
1745 2001-12-05 Akim Demaille <akim@epita.fr>
1746
1747 * src/lalr.c (initialize_F): Improve variable locality.
1748 Avoid variables used as mere abbreviations.
1749
1750 2001-12-05 Akim Demaille <akim@epita.fr>
1751
1752 * src/derives.c (print_derives): Display the ruleno.
1753 * src/lalr.c (initialize_F, transpose): Better variable locality
1754 to improve readability.
1755 Avoid variables used as mere abbreviations.
1756
1757 2001-12-05 Akim Demaille <akim@epita.fr>
1758
1759 * src/lalr.c (traverse): Use arrays instead of pointers.
1760
1761 2001-12-05 Akim Demaille <akim@epita.fr>
1762
1763 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1764 the handling of squeue.
1765 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1766
1767 2001-12-05 Akim Demaille <akim@epita.fr>
1768
1769 Because useless nonterminals are now kept alive (instead of being
1770 `destroyed'), we now sometimes examine them, and store information
1771 related to them. Hence we need to know their number, and adjust
1772 memory allocations.
1773
1774 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1775 static.
1776 * src/LR0.c (allocate_itemsets): The memory allocated to
1777 `symbol_count' was used for two different purpose: once to count
1778 the number of occurrences of each symbol, and later reassigned to
1779 `shift_symbol', containing the symbol that can be shifted from a
1780 given state.
1781 Deobfuscate, i.e., allocate, use and free `symbol_count' here
1782 only, and...
1783 (new_itemsets): Allocate `shift_symbol' here.
1784 (allocate_itemsets): symbol_count includes useless nonterminals.
1785 Make room for them.
1786 (free_storage): Use `free', not `XFREE', for pointers that cannot
1787 be null.
1788
1789 2001-12-05 Akim Demaille <akim@epita.fr>
1790
1791 * src/nullable.c (set_nullable): Deobfuscate the handling of
1792 ritem.
1793 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1794
1795 2001-12-05 Akim Demaille <akim@epita.fr>
1796
1797 * src/gram.c, src/gram.h (ritem_print): New.
1798 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1799 (This useless function was defined only to work around VMS linkers
1800 that can't handle compilation units with variables only).
1801 * src/reduce.c (dump_grammar): Use it to trace the construction of
1802 ritem.
1803
1804 2001-12-04 Paul Eggert <eggert@twinsun.com>
1805
1806 * src/bison.simple (union yyalloc): Change member names
1807 to be the same as the stack names.
1808 (yyparse): yyptr is now union yyalloc *, not char *.
1809 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
1810 and may generate better code on some machines.
1811 (yystpcpy): Use prototype if __STDC__ is defined, not just
1812 if __cplusplus is defined.
1813
1814 2001-11-30 Akim Demaille <akim@epita.fr>
1815
1816 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1817 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1818 Gettext doesn't compile cleanly, and dies with -Werror.
1819 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1820 Include WARNING_CFLAGS here.
1821 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1822 before being defined.
1823
1824 2001-11-27 Paul Eggert <eggert@twinsun.com>
1825
1826 * lib/quotearg.h (quotearg_n, quotearg_n_style):
1827 First arg is int, not unsigned.
1828 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1829 (SIZE_MAX, UINT_MAX): New macros.
1830 (quotearg_n_options): Abort if N is negative.
1831 Avoid overflow check on hosts where size_t is 64 bits and int
1832 is 32 bits, as overflow is impossible there.
1833 Fix off-by-one typo that caused unnecessary reallocation.
1834
1835 2001-11-29 Paul Eggert <eggert@twinsun.com>
1836
1837 Name space cleanup in generated parser.
1838
1839 * doc/bison.texinfo (Bison Parser): Discuss system headers
1840 and their effect on the user name space.
1841
1842 * src/bison.simple:
1843 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1844 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1845 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1846
1847 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
1848 on user names when possible.
1849
1850 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1851 Simplify test for whather <alloca.h> exists.
1852
1853 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1854
1855 (<stdio.h>): Include if YYDEBUG.
1856
1857 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
1858 ! defined (yyoverflow) && ! defined (yymemcpy).
1859
1860 (yymemcpy, yyparse): Rename local variables as needed so that
1861 they all begin with 'yy'.
1862
1863 (yystrlen, yystpcpy): New functions.
1864
1865 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1866 All uses changed.
1867
1868 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
1869 instead of relying on string.h functions. Use YYSTACK_ALLOC

1888
1889 Instead of mapping the LHS of unused rules to -1, keep the LHS

1893 * src/print.c (print_grammar): Adjust.
1894 * src/derives.c (set_derives): Likewise.

1927 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1928 an arbitrary restriction on hosts where size_t is wider than int.
1929
1930 (yyparse): Don't dump core if alloca or malloc fails; instead, report
1931 a parser stack overflow. Allocate just one block of memory for all
1932 three stacks, instead of allocating three blocks; this typically is
1933 faster and reduces fragmentation.
1934
1935 Do not limit the number of items in the stack to a value that fits
1936 in 'int', as this is an arbitrary limit on hosts with 64-bit
1937 size_t and 32-bit int.

2363
2364 * tests/calc.at, tests/output.at, tests/regression.at,
2365 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
2366 now the tests are run in private dirs, therefore AC_CLEANUP and

2368 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
2369 use abs. path to find config.h.
2370 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

2392 braces to pacify GCC's warnings for `if () if () {} else {}'.
2393 * src/lex.c (parse_percent_token): Replace equal_offset with
2394 arg_offset.
2395 arg is const.
2396 Be sure to strdup `arg' when used, since there is no reason for

3711
3712 2001-03-16 Akim Demaille <akim@epita.fr>
3713

3740 2001-02-08 Akim Demaille <akim@epita.fr>
3741
3742 * src/conflicts.c (conflict_report): Be sure not to append to res

3749 New, from fileutils 4.0.37.
3750 * configure.in: Require Autoconf 2.49c. I took some time before
3751 making this decision. This is the only way out for portability
3752 issues in Bison, it would mean way too much duplicate effort to
3753 import in Bison features implemented in 2.49c since 2.13.
3754 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
3755
3756 2001-02-02 Akim Demaille <akim@epita.fr>

3770
3771 2001-01-19 Akim Demaille <akim@epita.fr>
3772
3773 * src/lex.h: Rename all the tokens:
3774 s/\bENDFILE\b/tok_eof/g;
3775 s/\bIDENTIFIER\b/tok_identifier/g;

3789 * src/lex.c (percent_table): Also accept `%yacc',
3790 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3791 `%debug'.
3792 Handle the actions for `%semantic_parser' and `%pure_parser' here,
3793 instead of returning a token.
3794 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3795 * src/reader.c (read_declarations): Adjust.
3796 * src/files.c (open_files): Don't call `compute_base_names', don't
3797 compute `attrsfile' since they depend upon data which might be
3798 *in* the input file now.
3799 (output_files): Do it here.
3800 * src/output.c (output_headers): Document the fact that this patch
3801 introduces a guaranteed SEGV for semantic parsers.
3802 * doc/bison.texinfo: Document them.
3803 * tests/suite.at: Exercise these %options.

3823
3824 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

3826 FILE * parameters.
3827
3828 2000-12-20 Akim Demaille <akim@epita.fr>
3829
3830 * src/files.c (open_files): Actually the `.output' file is based

3833
3834 2000-12-20 Akim Demaille <akim@epita.fr>

3860 (stringappend): Be just like strcat but allocate.
3861 (base_names): Eve out from open_files.
3862 Try to simplify the rather hairy computation of base_name and
3863 short_base_name.
3864 (open_files): Use it.
3865 * tests/suite.at (Checking output file names): New test.
3866

3902
3903 2000-12-19 Akim Demaille <akim@epita.fr>
3904
3905 * src/files.c (open_files): Yipee! We no longer need all the code

3908 2000-12-19 Akim Demaille <akim@epita.fr>
3909

3938 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3939 prevents type checking.
3940 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3941 cast the value to (void *): assigning a `foo *' to a `void *'
3942 variable is valid.

3990 Qualify it `const'.
3991 (obstack_copy, obstack_copy0): Rename the second argument as
3992 `address' for consistency. Qualify it `const'.
3993 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
3994 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

4159 * src/derives.c, src/print.c, src/reduce.c: To ease the
4160 translation, move some `\n' out of the translated strings.
4161
4162 2000-10-02 Akim Demaille <akim@epita.fr>
4163
4164 The location tracking mechanism is precious for parse error
4165 messages. Nevertheless, it is enabled only when `@n' is used in
4166 the grammar, which is a different issue (you can use it in error
4167 message, but not in the grammar per se). Therefore, there should
4168 be another means to enable it.
4169
4170 * src/getargs.c (getargs): Support `--locations'.
4171 (usage): Report it.
4172 * src/getargs.h (locationsflag): Export it.
4173 * src/lex.c (percent_table): Support `%locations'.
4174 * src/reader.c (yylsp_needed): Remove this variable, now replaced
4175 with `locationsflag'.
4176 * doc/bison.texinfo: Document `--locations' and `%locations'.
4177 Sort the options.
4178 * tests/calc.m4: Test it.
4179
4180 For regularity of the names, replace each
4181 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4182 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4183 In addition replace each `flag' with `_flag'.
4184
4185 2000-10-02 Akim Demaille <akim@epita.fr>
4186
4187 Also test parse error messages, including with YYERROR_VERBOSE.
4188
4189 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4190 associative).
4191 Use it to check the computations.
4192 Use it to check `nonassoc' is honored.
4193 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4194 `--yyerror-verbose'.
4195 (_AT_CHECK_CALC): Adjust to this option.
4196 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4197
4198 2000-10-02 Akim Demaille <akim@epita.fr>
4199
4200 Test also `--verbose', `--defines' and `--name-prefix'. Testing
4201 the latter demonstrates a flaw in the handling of non debugging
4202 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4203 was used in order to simplify:
4204
4205 #if YYDEBUG
4206 if (yydebug)
4207 {
4208 ...
4209 }
4210 #endif
4211
4212 into
4213
4214 if (yydebug)
4215 {
4216 ...
4217 }
4218
4219 unfortunately this leads to a CPP conflict when
4220 `--name-prefix=foo' is used since it produces `#define yydebug
4221 foodebug'.
4222
4223 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4224 (YYDPRINTF): New macro.
4225 Spread its use.
4226 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4227 the bison options.
4228 Also test `--verbose', `--defines' and `--name-prefix'.
4229
4230 2000-10-02 Akim Demaille <akim@epita.fr>
4231
4232 Improve the readability of the produced parsers.
4233
4234 * src/bison.s1: Formatting changes.
4235 Improve the comment related to the `$' mark.
4236 (yydefault): Don't fall through to `yyresume': `goto' there.
4237 * src/output.c (output_parser): When the `$' is met, skip the end
4238 of its line.
4239 New variable, `number_of_dollar_signs', to check there's exactly
4240 one `$' in the parser skeleton.
4241
4242 2000-10-02 Akim Demaille <akim@epita.fr>
4243
4244 * lib/xstrdup.c: New file, from the fileutils.
4245 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4246 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4247 instead of strlen + xmalloc + strcpy.
4248 * src/symtab.c (copys): Remove, use xstrdup instead.
4249
4250 2000-10-02 Akim Demaille <akim@epita.fr>
4251
4252 * src/gram.h (associativity): New enum type which replaces the
4253 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4254 `right_assoc', `left_assoc' and `non_assoc'.
4255 Adjust all dependencies.
4256 * src/reader.c: Formatting changes.
4257 (LTYPESTR): Don't define it, use it as a literal in
4258 `reader_output_yylsp'.
4259 * src/symtab.h (symbol_class): New enum type which replaces the
4260 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4261 `sunknown', `stoken and `snterm'.
4262
4263 2000-10-02 Akim Demaille <akim@epita.fr>
4264
4265 * src/getargs.c (fixed_outfiles): Rename as...
4266 (yaccflag): for consistency and accuracy.
4267 Adjust dependencies.
4268
4269 2000-10-02 Akim Demaille <akim@epita.fr>
4270
4271 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4272 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
4273 difficult and introduced a lot of core dump. It turns out that
4274 Bison used an implementation of `xmalloc' based on `calloc', and
4275 at various places it does depend upon the initialization to 0. I
4276 have not tried to isolate the pertinent places, and all the former
4277 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
4278 someone should address this issue.
4279
4280 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4281 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

4288
4289 Various anti-`extern in *.c' changes.
4290
4291 * src/system.h: Include `assert.h'.
4292
4293 2000-10-02 Akim Demaille <akim@epita.fr>
4294
4295 * src/state.h (nstates, final_state, first_state, first_shift)
4296 (first_reduction): Move their exportation from here...
4297 * src/LR0.h: to here.
4298 Adjust dependencies.
4299 * src/getargs.c (statisticsflag): New variable.
4300 Add support for `--statistics'.
4301 Adjust dependencies.

4377 output_short_table.
4378
4379 2000-10-02 Akim Demaille <akim@epita.fr>
4380
4381 `user_toknums' is output as a `short[]' in `output.c', while it is
4382 defined as a `int[]' in `reader.c'. For consistency with the
4383 other output tables, `user_toknums' is now defined as a table of
4384 shorts.
4385
4386 * src/reader.c (user_toknums): Be a short table instead of an int
4387 table.
4388 Adjust dependencies.

4425 inclusion.
4426 Don't define PARAMS.
4427 * src/system.h: Define PARAMS.
4428 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4429 purpose of config.h. system.h must not try to fix wrong
4430 definitions in config.h.
4431
4432 2000-09-20 Akim Demaille <akim@epita.fr>
4433

4639
4640 2000-03-17 Akim Demaille <akim@epita.fr>
4641
4642 * src/reader.c (copy_string): New function, factored out from:
4643 (copy_action): Use it.
4644 (copy_guard): Likewise.
4645
4646 2000-03-17 Akim Demaille <akim@epita.fr>
4647
4648 Change the handling of @s so that they behave exactly like $s.
4649 There is now a pseudo variable @$ (readble and writable), location
4650 of the lhs of the rule (by default ranging from the location of
4651 the first symbol of the rhs, to the location of the last symbol,
4652 or, if the rhs is empty, YYLLOC).
4653
4654 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4655 yyval.
4656 (yyparse): When providing a default semantic action, provide a
4657 default location action.
4658 (after the $): No longer change `*YYLSP', just stack YYLOC the
4659 same way you stack YYVAL.
4660 * src/reader.c (read_declarations): Use warns.
4661 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4662 (copy_action, case '@'): Likewise.
4663 Use a standard error message, to save useless work from
4664 translators.
4665

4685
4686 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
4687 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4688 One `#if YYDEBUG' remains, since it uses variables which are
4689 defined only if `YYDEBUG != 0'.
4690
4691 2000-03-16 Akim Demaille <akim@epita.fr>
4692

4713 Bump to bison 1.28a, 1.29 has never been released.
4714 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
4715 handled via src/Makefile.am.

4727 builddir.
4728 * acinclude.m4: Remove, replaced by the directory m4.
4729 * m4/Makefile.am (EXTRA_DIST): New variable.
4730 * m4/gettext.m4: New file, from the fileutils.

5411 always contain the token. This includes growing the token
5412 buffer while reading an integer.
5413 (parse_percent_token): Replaced if-else statement with percent_table.
5414 (parse_percent_token): Added % declarations as another
5415 way to specify the flags -n, -l, and -r. Also added hooks for
5416 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
5417 major changes to files.c.
