3 | * src/gram.h (rule_s): prec and precsym are now pointers | |
4 | to the bucket giving the priority/associativity. | |
5 | Member `associativity' removed: useless. | |
6 | * src/reduce.c, src/conflicts.c: Adjust. | |

10 | * src/lalr.c, src/LR0.c, src/closure.c, src/gram.c, src/reduce.c: | |
11 | Properly escape the symbols' TAG when outputting them. | |

19 | ||
20 | * src/lalr.h, src/lalr.c (LAruleno): Replace with... | |
21 | (LArule): this, which is an array to rule_t*. | |
22 | * src/print.c, src/conflicts.c: Adjust. | |

27 | * src/gram.h (rule_t): Rename `number' as `user_number'. | |
28 | `number' is a new member. | |
29 | Adjust dependencies. | |
30 | * src/reduce.c (reduce_grammar_tables): Renumber rule_t.number. | |

33 | ||
34 | As a result of the previous patch, it is no longer needed | |
35 | to reorder ritem itself. | |
36 | ||
37 | * src/reduce.c (reduce_grammar_tables): Don't sort RITEM. | |
38 | ||

39 | 2002-04-07 Akim Demaille <akim@epita.fr> |
40 | ||
41 | Be sure never to walk through RITEMS, but use only data related to | |
42 | the rules themselves. RITEMS should be banished. | |
43 | ||
44 | * src/output.c (output_token_translations): Rename as... | |
45 | (prepare_tokens): this. | |
46 | In addition to `translate', prepare the muscles `tname' and | |
47 | `toknum', which were handled by... | |
48 | (output_rule_data): this. | |
49 | Remove, and move the remainder of its outputs into... | |
50 | (prepare_rules): this new routines, which also merges content from | |
51 | (output_gram): this. | |
52 | (prepare_rules): Be sure never to walk through RITEMS. | |
53 | (output_stos): Rename as... | |
54 | (prepare_stos): this. | |
55 | (output): Always invoke prepare_states, after all, just don't use it | |
56 | in the output if you don't need it. | |

58 | 2002-04-07 Akim Demaille <akim@epita.fr> |
59 | ||
60 | * src/LR0.c (new_state): Display `nstates' as the name of the | |
61 | newly created state. | |
62 | Adjust to initialize first_state and last_state if needed. | |
63 | Be sure to distinguish the initial from the final state. | |
64 | (new_states): Create the itemset of the initial state, and use | |
65 | new_state. | |
66 | * src/closure.c (closure): Now that the initial state has its | |
67 | items properly set, there is no need for a special case when | |
68 | creating `ruleset'. | |
69 | ||
70 | As a result, now the rule 0, reducing to $axiom, is visible in the | |
71 | outputs. Adjust the test suite. | |
72 | ||
73 | * tests/conflicts.at (Solved SR Conflicts) | |
74 | (Unresolved SR Conflicts): Adjust. | |
75 | * tests/regression.at (Web2c Report, Rule Line Numbers): Idem. | |
76 | * tests/conflicts.at (S/R in initial): New. | |

78 | 2002-04-07 Akim Demaille <akim@epita.fr> |
79 | ||
80 | * src/LR0.c (allocate_itemsets): Don't loop over ritem: loop over | |
81 | the RHS of the rules. | |
82 | * src/output.c (output_gram): Likewise. | |
83 | ||
bba97eb2 AD |
84 | 2002-04-07 Akim Demaille <akim@epita.fr> |
85 | ||
86 | * src/gram.h (rule_t): `lhs' is now a pointer to the symbol's | |
87 | bucket. | |
88 | Adjust all dependencies. | |
89 | * src/reduce.c (nonterminals_reduce): Don't forget to renumber the | |
90 | `number' of the buckets too. | |
91 | * src/gram.h: Include `symtab.h'. | |
92 | (associativity): Move to... | |
93 | * src/symtab.h: here. | |
94 | No longer include `gram.h'. | |

101 | * src/gram.h (rule_t): `number' is a new member. | |
102 | * src/reader.c (packgram): Set it. | |
103 | * src/reduce.c (reduce_grammar_tables): Move the useless rules at | |
104 | the end of `rules', and count them out of `nrules'. | |
105 | (reduce_output, dump_grammar): Adjust. | |
106 | * src/print.c (print_grammar): It is no longer needed to check for | |
107 | the usefulness of a rule, as useless rules are beyond `nrules + 1'. | |
108 | * tests/reduce.at (Reduced Automaton): New test. | |

110 | 2002-04-07 Akim Demaille <akim@epita.fr> |
111 | ||
112 | * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a | |
113 | lacking `+ 1' to nrules, Bison reported as useless a token if it | |
114 | was used solely to set the precedence of the last rule... | |

116 | 2002-04-07 Akim Demaille <akim@epita.fr> |

119 | name in #line, to avoid useless diffs between two identical | |
120 | outputs under different names. | |

395 | hard coded name. | |

412 | Remove the support for C++ namespace cleanliness; it was | |
413 | causing more problems than it was curing, since it didn't work | |
414 | properly on some nonstandard C++ compilers. This can wait | |
415 | for a proper C++ parser. | |
416 | ||
417 | * NEWS: Document this. | |
418 | * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention | |
419 | of C++, as it's treated like C now. | |
420 | * src/bison.simple (YYSTD): Remove. | |
421 | (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL): | |
422 | Treat C++ just like Standard C instead of trying to support | |
423 | namespace cleanliness. | |

458 | ||
459 | * data/bison.c++: Replace some direct m4 expansions by constants. Be | |

463 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
464 | ||
465 | * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in | |
466 | C++ parsers. | |
467 | (yy::b4_name::parse): Use print_. | |
468 | ||

488 | 2002-02-05 Akim Demaille <akim@epita.fr> |
489 | ||
490 | * data/bison.c++: Adjust to the M4 back end. | |
491 | More is certainly needed. | |
492 | ||
be2a1a68 AD |
493 | 2002-02-05 Akim Demaille <akim@epita.fr> |
494 | ||
495 | Give a try to M4 as a back end. | |
496 | ||
497 | * lib/readpipe.c: New, from wdiff. | |
498 | * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and | |
499 | BISON_HAIRY. | |
500 | * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS | |
501 | specific values. Now it is m4 that performs the lookup. | |
502 | * src/parse-skel.y: Remove. | |
503 | * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New. | |
504 | * src/output.c (actions_output, guards_output) | |
505 | (token_definitions_output): No longer keeps track of the output | |
506 | line number, hence remove the second argument. | |
507 | (guards_output): Check against the guard member of a rule, not the | |
508 | action member. | |
509 | Adjust callers. | |
510 | (output_skeleton): Don't look for the skeleton location, let m4 do | |
511 | that. | |
512 | Create `/tmp/muscles.m4'. This is temporary, a proper temporary | |
513 | file will be used. | |
514 | Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton. | |
515 | (prepare): Given that for the time being changesyntax is not | |
516 | usable in M4, rename the muscles using `-' to `_'. | |
517 | Define `defines_flag', `output_parser_name' and `output_header_name'. | |
518 | * src/output.h (actions_output, guards_output) | |
519 | (token_definitions_output): Adjust prototypes. | |
520 | * src/scan-skel.l: Instead of scanning the skeletons, it now | |
521 | processes the output of m4: `__oline__' and `#output'. | |
522 | * data/bison.simple: Adjust to be used by M4(sugar). | |
523 | * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up | |
524 | to date. | |
525 | * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR' | |
526 | instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'. | |
527 | * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New, | |
528 | shamelessly stolen from CVS Autoconf. | |

545 | ||
894dd62e PE |
546 | 2002-01-29 Paul Eggert <eggert@twinsun.com> |
547 | ||
548 | * src/bison.simple (YYSIZE_T): Do not define merely because | |
549 | YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined. | |
550 | On some platforms, <alloca.h> does not declare YYSTD (size_t). | |
551 | ||
82841af7 AD |
552 | 2002-01-27 Akim Demaille <akim@epita.fr> |
553 | ||
554 | Fix `%nonassoc and eof'. | |
555 | ||
556 | * src/state.c (errs_dup): Aaaah! The failure was due to bytes | |
557 | which were not properly copied! Replace | |
558 | memcpy (res->errs, src->errs, src->nerrs); | |
559 | with | |
560 | memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0])); | |
561 | !!! | |
562 | * tests/regression.at (%nonassoc and eof): Adjust to newest | |
563 | Autotest: `.' is not in the PATH. | |

572 | ||
573 | * tests/actions.at, tests/calc.at, tests/headers.at, | |
574 | * tests/torture.at: Adjust to the newest Autotest which no longer | |
575 | forces `.' in the PATH. | |

583 | ||
584 | Bison dumps core when trying to complain about broken input files. | |
585 | Reported by Cris van Pelt. | |
586 | ||
587 | * src/lex.c (parse_percent_token): Be sure to set token_buffer. | |
588 | * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge | |
589 | into... | |
590 | (Invalid inputs): Strengthen: exercise parse_percent_token. | |

593 | ||

610 | ||
611 | * tests/output.at: New test. | |
612 | * src/files.c (compute_base_names): Don't map extensions when | |
613 | the YACC flag is set, use defaults. | |
614 | Reported by Evgeny Stambulchik. | |

616 | 2002-01-20 Marc Autret <marc@gnu.org> |
617 | ||
bb0146c2 | 618 | * src/system.h: Need to define __attribute__ away for non-GCC |
44ea3fbd MA |
619 | compilers as well (i.e. the vendor C compiler). |
620 | Suggested by Albert Chin-A-Young. | |
621 | ||
338963d1 TVH |
622 | 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be> |
623 | ||
624 | * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the | |
625 | canonical definition. | |
626 | * src/system.h: Use the canonical definition for PARAMS (avoids | |
627 | a conflict with the macro from lib/hash.h). | |

c57b2479 AD |
629 | 2002-01-11 Akim Demaille <akim@epita.fr> |
630 | ||
631 | * configure.in: Use AC_FUNC_STRNLEN. | |
d9e9746c | 632 | Fixes the failures observed on AIX 4.3 by H.Merijn Brand. |

634 | 2002-01-09 Akim Demaille <akim@epita.fr> |
635 | ||
636 | * src/files.c, src/files.h (output_infix): New. | |
637 | (tab_extension): Remove. | |
638 | (compute_base_names): Compute the former, drop the latter. | |
639 | * src/output.c (prepare): Insert the muscles `output-infix', and | |
640 | `output-suffix'. | |

659 | (getargs): Use it to convert DOSish file names. | |
660 | * src/files.c (base_name): Rename as full_base_name to avoid | |
661 | clashes with `base_name ()'. | |
662 | (filename_split): New. | |

666 | ||
667 | * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c: | |
668 | New, stolen from the Fileutils 4.1. | |
669 | * lib/Makefile.am (libbison_a_SOURCES): Adjust. | |
670 | * configure.in: Check for the presence of memrchr, and of its | |
671 | prototype. | |
672 | ||
a67cef01 TVH |
673 | 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be> |
674 | ||
675 | * lib/hash.h (__P): Added definition for this macro. | |
676 | * src/Makefile.am: Add parse-skel.c and scan-skel.c to | |
677 | BUILT_SOURCES, to ensure they are generated first. | |
678 | * src/parse-skel.y: Use YYERROR_VERBOSE instead of | |
679 | %error-verbose to allow bootstrapping with bison 1.30x. | |
680 | ||
2b25d624 AD |
681 | 2002-01-06 Akim Demaille <akim@epita.fr> |
682 | ||
683 | * src/reader.c (parse_braces): Don't fetch the next char, the | |
684 | convention is to fetch on entry. | |
685 | * tests/torture.at (GNU Cim Grammar): Reintroduce their weird | |
686 | 'switch' without a following semicolon. | |
687 | * tests/regression.at (braces parsing): New. | |
688 | ||
3460813b AD |
689 | 2002-01-06 Akim Demaille <akim@epita.fr> |
690 | ||
691 | Bison is dead wrong in its RR conflict reports. | |

695 | ||
73784c64 AD |
696 | 2002-01-06 Akim Demaille <akim@epita.fr> |
697 | ||
698 | Creating package.m4 from configure.ac causes too many problems. | |
699 | ||
700 | * tests/Makefile.am (package.m4): Create it by hand, | |
701 | AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf. | |
702 | ||
25d81090 AD |
703 | 2002-01-06 Akim Demaille <akim@epita.fr> |
704 | ||
705 | * src/Makefile.am (bison_SOURCES): Add parse-skel.h and | |

708 | 2002-01-04 Paul Eggert <eggert@twinsun.com> |
709 | ||

718 | 2002-01-03 Akim Demaille <akim@epita.fr> |
719 | ||
720 | * src/parse-skel.y (process_skeleton): Don't bind the parser's | |
721 | tracing code to --trace, wait for a better --trace option, with | |
722 | args. | |
723 | ||
7ea5e977 AD |
724 | 2002-01-03 Akim Demaille <akim@epita.fr> |
725 | ||
726 | * src/bison.simple (YYSTDERR): Remove, replace `stderr'. | |
727 | The ISO C++ standard is extremely clear about it: stderr is | |
728 | considered a macro, not a regular symbol (see table 94 `Header | |
729 | <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files). | |
730 | Therefore std:: does not apply to it. It still does with fprintf. | |
731 | Also, s/cstdio.h/cstdio/. | |
732 | ||
fab5b110 AD |
733 | 2002-01-03 Akim Demaille <akim@epita.fr> |

736 | for non system headers. | |
737 | ||
aed7fd9b AD |
738 | 2002-01-02 Akim Demaille <akim@epita.fr> |
739 | ||
740 | Equip the skeleton chain with location tracking, runtime trace, | |
741 | pure parser and scanner. | |
742 | ||
743 | * src/parse-skel.y: Request a pure parser, locations, and prefix | |
744 | renaming. | |
745 | (%union): Having several members with the same type does not help | |
746 | type mismatches, simplify. | |
747 | (YYPRINT, yyprint): New. | |
748 | (yyerror): ``Rename'' (there is a #define yyerror skel_error) as... | |
749 | (skel_error): this. | |
750 | Handle locations. | |
751 | * src/scan-skel.l: Adjust to these changes. | |
752 | * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP) | |
753 | (LOCATION_PRINT, skel_control_t): New. | |
754 | ||
24fad99e AD |
755 | 2001-12-30 Akim Demaille <akim@epita.fr> |
756 | ||
757 | * src/parse-skel.y: Get rid of the shift/reduce conflict: | |
758 | replace `gb' with BLANKS. | |
759 | * src/scan-skel.l: Adjust. | |
760 | ||
a4b36db4 AD |
761 | 2001-12-30 Akim Demaille <akim@epita.fr> |
762 | ||
763 | * src/system.h: We don't need nor want bcopy. | |
764 | Throw away MS-DOS crap: we don't need getpid. | |
765 | * configure.in: We don't need strndup. It was even causing | |
766 | problems: because Flex includes the headers *before* us, | |
767 | _GNU_SOURCE is not defined by config.h, and therefore strndup was | |
768 | not visible. | |
769 | * lib/xstrndup.c: New. | |
770 | * src/scan-skel.l: Use it. | |
771 | Be sure to initialize yylval.muscle member when scanning a MUSCLE. | |
772 | * src/parse-skel.y: Use %directives instead of #defines. | |

776 | * src/skeleton.h: New. | |
777 | * src/output.c (output_parser, output_master_parser): Remove, dead | |
778 | code. | |
779 | * src/output.h (get_lines_number, actions_output, guards_output) | |
780 | (token_definitions_output): Prototype them. | |
781 | * src/parse-skel.y: Add the license notice. | |
782 | Include output.h and skeleton.h. | |
783 | (process_skeleton): Returns void, and takes a single parameter. | |
784 | * src/scan-skel.l: Add the license notice. | |
785 | Include skeleton.h. | |
786 | Don't use %option yylineno: it seems that then Flex imagines | |
787 | REJECT has been used, and therefore it won't reallocate its | |
788 | buffers (which makes no other sense to me than a bug). It results | |
789 | in warnings for `unused: yy_flex_realloc'. | |

796 | (MUSCLE_INSERT_PREFIX): Move from here... | |
797 | ||
798 | * src/bison.hairy: Add a section directive. Put braces around muscle | |
799 | names. This parser skeleton is still broken, but Bison should not | |
800 | choke on a bad muscle 'syntax'. | |
801 | * src/bison.simple: Add a section directive. Put braces around muscle | |
802 | names. | |
803 | ||
804 | * src/files.h (strsuffix, stringappend): Add declarations. | |

807 | ||
808 | * src/files.c (strsuffix, stringappend): No longer static. These | |
809 | functions are used in the skeleton parser. | |
810 | (tab_extension): New. | |
811 | (compute_base_names): Use the computations done in this function | |
fab5b110 | 812 | to guess if the generated parsers should have '.tab' in their |
9b3add5b RA |
813 | names. |
814 | (short_base_name): No longer static. | |
815 | ||
816 | * src/output.c (output_skeleton): New. | |
817 | (output): Disable call to output_master_parser, and give a try to | |
818 | a new skeleton handling system. | |
819 | (guards_output, actions_output): No longer static. | |
820 | (token_definitions_output, get_lines_number): No longer static. | |

822 | * configure.in: Use AM_PROG_LEX and AC_PROG_YACC. | |

837 | %name-prefix. | |

881 | Don't store the token defs in a muscle, just be ready to output it | |
882 | on command. Now possible via `symbols'. Fixes a memory leak. | |

968 | Drop sprec. | |

980 | 2001-12-29 Akim Demaille <akim@epita.fr> |
981 | ||
982 | * tests/regression.at (Web2c Actions): Blindly move the actual | |
983 | output as expected output. The contents *seem* right to me, but I | |
984 | can't pretend reading perfectly parser tables... Nonetheless, all | |
985 | the other tests pass correctly, the table look OK, even though the | |
986 | presence of `$axiom' is to be noted: AFAICS it is useless (but | |
987 | harmless). | |

990 | ||
991 | * src/reader.c (readgram): Don't add the rule 0 if there were no | |
992 | rules read. In other words, add it _after_ having performed | |
993 | grammar sanity checks. | |
994 | Fixes the `tests/regression.at (Invalid input: 1)' Failure. | |

78d5bae9 AD |
996 | 2001-12-29 Akim Demaille <akim@epita.fr> |

1008 | 2001-12-29 Akim Demaille <akim@epita.fr> |
1009 | ||
1010 | Fix the `GAWK Grammar' failure. | |
1011 | ||
1012 | * src/LR0.c (final_state): Initialize to -1 so that we do compute | |
1013 | the reductions of the first state which was mistakenly confused | |
1014 | with the final state because precisely final_state was initialized | |
1015 | to 0. | |
1016 | * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads, | |
1017 | now noticed by Bison. | |
1018 | * tests/regression.at (Rule Line Numbers): Adjust: state 0 does | |
1019 | have a reduction on $default. | |

1033 | (lalr): Call it when --trace-flag. | |
1034 | * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads | |
1035 | are dumped. | |
1036 | ||
3d4daee3 AD |
1037 | 2001-12-29 Akim Demaille <akim@epita.fr> |
1038 | ||

1041 | * src/reduce.c (dump_grammar, useful_production, reduce_output) | |

1044 | * src/nullable.c (set_nullable): Likewise. | |
1045 | * src/lalr.c (build_relations): Likewise. | |
1046 | * tests/sets.at (Nullable): Adjust. | |

0d8a7363 AD |
1063 | 2001-12-27 Paul Eggert <eggert@twinsun.com> |
1064 | ||
1065 | * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special | |
1066 | cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and | |
1067 | Sparc, as they were causing more porting problems than the | |
1068 | (minor) performance improvement was worth. | |
1069 | ||
1070 | Also, catch up with 1.31's YYSTD. | |
1071 | ||
3db472b9 AD |
1072 | 2001-12-27 Akim Demaille <akim@epita.fr> |
1073 | ||
1074 | * src/output.c (output_gram): Rely on nritems, not the | |
1075 | 0-sentinel. See below. | |
1076 | Use -1 as separator, not 0. | |
1077 | * src/bison.simple (yyparse): Subtract 1 to the rule numbers. | |
1078 | Rely on -1 as separator in yyrhs, instead of 0. | |
1079 | * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue | |
1080 | twice `Now at end of input', therefore there are two lines less to | |
1081 | expect. | |
1082 | ||
b365aa05 AD |
1083 | 2001-12-27 Akim Demaille <akim@epita.fr> |
1084 | ||
1085 | * tests/regression.at (Unresolved SR Conflicts): | |
1086 | (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes | |
1087 | below. | |
1088 | ||
30171f79 AD |
1089 | 2001-12-27 Akim Demaille <akim@epita.fr> |
1090 | ||
1091 | * src/LR0.c (new_state): Recognize the final state by the fact it | |
1092 | is reached by eoftoken. | |
1093 | (insert_start_shifting_state, insert_eof_shifting_state) | |
1094 | (insert_accepting_state, augment_automaton): Remove, since now | |
1095 | these states are automatically computed from the initial state. | |
1096 | (generate_states): Adjust. | |
1097 | * src/print.c: When reporting a rule number to the user, substract | |
1098 | 1, so that the axiom rule is rule 0, and the first user rule is 1. | |
1099 | * src/reduce.c: Likewise. | |
1100 | * src/print_graph.c (print_core): For the time being, just as for | |
1101 | the report, depend upon --trace-flags to dump the full set of | |
1102 | items. | |
1103 | * src/reader.c (readgram): Once the grammar read, insert the rule | |
1104 | 0: `$axiom: START-SYMBOL $'. | |
1105 | * tests/set.at: Adjust: rule 0 is now displayed, and since the | |
1106 | number of the states has changed (the final state is no longer | |
1107 | necessarily the last), catch up. | |
1108 | ||

1109 | 2001-12-27 Akim Demaille <akim@epita.fr> |
1110 | ||
1111 | Try to make the use of the eoftoken valid. Given that its value | |
1112 | is 0 which was also used as a sentinel in ritem, (i) make sure >= 0 | |
1113 | is used instead of > 0 where appropriate, (ii), depend upon nritems | |
1114 | instead of the 0-sentinel. | |
1115 | ||
1116 | * src/gram.h, src/gram.c (nritems): New. | |
1117 | Expected to be duplication of nitems, but for the time being... | |
1118 | * src/reader.c (packgram): Assert nritems and nitems are equal. | |
1119 | * src/LR0.c (allocate_itemsets, new_itemsets): Adjust. | |
1120 | * src/closure.c (print_closure, print_fderives): Likewise. | |

1125 | 2001-12-27 Akim Demaille <akim@epita.fr> |
1126 | ||
1127 | * src/main.c (main): If there are complains after grammar | |
1128 | reductions, then output the report anyway if requested, then die. | |
1129 | * src/symtab.c (bucket_new): Initialize `value' to -1, not 0. | |
1130 | * src/reader.c (eoftoken): New. | |
1131 | (parse_token_decl): If the token being defined has value `0', it | |
1132 | is the eoftoken. | |
1133 | (packsymbols): No longer hack `tags' to insert `$' by hand. | |
1134 | Be sure to preserve the value of the eoftoken. | |
1135 | (reader): Make sure eoftoken is defined. | |
1136 | Initialize nsyms to 0: now eoftoken is created just like the others. | |
1137 | * src/print.c (print_grammar): Don't special case the eof token. | |
1138 | * src/regression.at: Adjust: `$' has value 0, not -1, which was a | |
1139 | lie anyway, albeit pleasant. | |
1140 | * tests/calc.at: Exercise error messages with eoftoken. | |
1141 | Change the grammar so that empty input is invalid. | |
1142 | Adjust expectations. | |
1143 | When yyungeting, be sure to use a valid yylloc: use last_yylloc. | |

1233 | the switch/case/break flesh. | |
1234 | Don't parse the user action that might follow the guard, let... | |
1235 | (readgram): do it, i.e., now, there can be an action after a | |
1236 | guard. | |
1237 | In other words the guard is just explicitly optional. | |

1246 | required. | |
1247 | * src/main.c (main): Adjust. | |

1279 | integer when referring to a state. | |
1280 | As much as possible, depend upon nlookaheads, instead of the | |
1281 | `lookaheadsp' member of the following state (since lookaheads of | |
1282 | successive states are successive, the difference between state n + 1 | |
1283 | and n served as the number of lookaheads for state n). | |

1521 | * src/lex.c (literalchar): Don't escape the special characters, | |
1522 | just decode them, and keep them as char (before, eol was output as | |
1523 | the 2 char string `\n' etc.). | |
1524 | * src/output.c (output_rule_data): Use quotearg to output the | |
1525 | token strings. | |

1529 | * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE): | |
1530 | Do not infringe on the global user namespace when using C++. | |
1531 | (YYFPRINTF, YYSTDERR): New macros, needed for the above. | |
1532 | All uses of `fprintf' and `stderr' changed. | |
1533 | ||

1538 | The computation of nullable is broken: it doesn't handle empty | |
1539 | RHS's properly. | |
1540 | ||
1541 | * tests/torture.at (GNU AWK Grammar): New. | |
1542 | * tests/sets.at (Nullable): New. | |
1543 | * src/nullable.c (set_nullable): Instead of blindly looping over | |
1544 | `ritems', loop over the rules, and then over their rhs's. | |
1545 | ||
1546 | Work around Autotest bugs. | |
1547 | ||
1548 | * src/warshall.c (bitmatrix_print): Don't use `+--+' as table | |
1549 | frame, because Autotest understand lines starting with a `+' as | |
1550 | traces from the shell. Then, they are not processed properly. | |
1551 | Admittedly an Autotest bug, but we don't have time to wait for | |
1552 | Autotest to catch up. | |
1553 | * tests/regression.at (Broken Closure): Adjust to the new table | |
1554 | frames. | |
1555 | Move to... | |
1556 | * tests/sets.at: here. | |

1565 | * src/print.c (print_actions): Output the handling of `$' as the | |
1566 | traces do: shifting the token EOF. Before EOF was treated as a | |
1567 | nonterminal. | |
1568 | * tests/regression.at: Adjust some tests. | |
1569 | * src/print_graph.c (print_core): Complete the set of items via | |
1570 | closure. The next-to-final and final states are still unsatisfying, | |
1571 | but that's to be addressed elsewhere. | |
1572 | No longer output the rule numbers, but do output the state number. | |
1573 | A single loop for the shifts + gotos is enough, but picked a | |
1574 | distinct color for each. | |
1575 | (print_graph): Initialize and finalize closure. | |

1626 | ||
1627 | * src/state.h (shifts): Remove the `number' member: shifts are | |
1628 | attached to state, hence no longer need to be labelled with a | |
1629 | state number. | |
1630 | ||
190c4f5f AD |
1631 | 2001-12-10 Akim Demaille <akim@epita.fr> |
1632 | ||
1633 | Now that states have a complete set of members, the linked list of | |
1634 | shifts is useless: just fill directly the state's shifts member. | |

1636 | * src/state.h (shifts): Remove the `next' member. | |
1637 | * src/LR0.c (first_state, last_state): Remove. | |
1638 | Adjust the callers. | |
1639 | (augment_automaton): Don't look for the shifts that must be added | |
1640 | a shift on EOF: it is those of the state we looked for! But now, | |
1641 | since shifts are attached, it is no longer needed to looking | |
1642 | merely by its id: its number. | |

1644 | 2001-12-10 Akim Demaille <akim@epita.fr> |
1645 | ||
1646 | * src/LR0.c (augment_automaton): Better variable locality. | |
1647 | Remove an impossible branch: if there is a state corresponding to | |
1648 | the start symbol being shifted, then there is shift for the start | |
1649 | symbol from the initial state. | |

74392f6a AD |
1651 | 2001-12-10 Akim Demaille <akim@epita.fr> |
1652 | ||
1653 | * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state' | |

1655 | invoked. | |
1656 | * tests/regression.at (Rule Line Numbers): Adjust. | |

1677 | 2001-12-10 Akim Demaille <akim@epita.fr> |

1679 | * src/LR0.c: Attach shifts to states as soon as they are | |
1680 | computed. | |
1681 | * src/lalr.c (set_state_table): Instead of assigning shifts to | |
1682 | state, just assert that the mapping was properly done. | |

1688 | (insert_eof_shifting_state, insert_accepting_state): New. | |
1689 | (augment_automaton): Adjust. | |
1690 | Better locality of the variables. | |
1691 | When looking if the start_symbol is shifted from the initial | |
1692 | state, using `while (... symbol != start_symbol ...)' sounds | |
1693 | better than `while (... symbol < start_symbol ...)': If fail | |
1694 | to see how the order between symbols could be relevant! | |

1696 | 2001-12-10 Akim Demaille <akim@epita.fr> |
1697 | ||
1698 | * src/getargs.h: Don't declare `spec_name_prefix' and | |
1699 | `spec_file_prefix', declared by src/files.h. | |
1700 | * src/files.c, src/files.h: Default for spec_name_prefix is "yy". | |

1702 | * src/output.c (prepare): Adjust. | |

1706 | 2001-12-10 Akim Demaille <akim@epita.fr> |
1707 | ||

1717 | Now that states have a complete set of members, the linked list of | |

1724 | (save_reductions): Don't link the new reductions, store them in | |

1726 | * src/lalr.c (set_state_table): No need to attach reductions to | |
1727 | states, it's already done. | |
1728 | * src/output.c (output_actions): No longer free the shifts, then | |
1729 | the reductions, then the states: free all the states and their | |
1730 | members. | |

1737 | * src/muscle_tab.c: Don't include xalloc.h and string.h: that's |
