| 5 | (error_token_number): Initialize. | |
| 6 | * src/reader.c (grammar, start_flag, startval, typed, lastprec): | |

| 12 | ||
| 13 | * src/gram.h (rule_s): prec and precsym are now pointers | |
| 14 | to the bucket giving the priority/associativity. | |
| 15 | Member `associativity' removed: useless. | |
| 16 | * src/reduce.c, src/conflicts.c: Adjust. | |

| 19 | ||
| 20 | * src/lalr.c, src/LR0.c, src/closure.c, src/gram.c, src/reduce.c: | |
| 21 | Properly escape the symbols' TAG when outputting them. | |

23 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 24 | ||
| 25 | * src/lalr.h (LA): Is a bitsetv, not bitset*. | |
| 26 | ||
| 27 | ||
| b0299a2e AD |
28 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 29 | ||
| 30 | * src/lalr.h, src/lalr.c (LAruleno): Replace with... | |
| 31 | (LArule): this, which is an array to rule_t*. | |
| 32 | * src/print.c, src/conflicts.c: Adjust. | |
| 33 | ||
| 34 | ||
| d7e1f00c AD |
35 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 36 | ||
| 37 | * src/gram.h (rule_t): Rename `number' as `user_number'. | |
| 38 | `number' is a new member. | |
| 39 | Adjust dependencies. | |
| 40 | * src/reduce.c (reduce_grammar_tables): Renumber rule_t.number. | |
| 41 | ||
| cc9305dd AD |
42 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 43 | ||
| 44 | As a result of the previous patch, it is no longer needed | |
| 45 | to reorder ritem itself. | |
| 46 | ||
| 47 | * src/reduce.c (reduce_grammar_tables): Don't sort RITEM. | |
| 48 | ||
| b0940840 AD |
49 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 50 | ||
| 51 | Be sure never to walk through RITEMS, but use only data related to | |
| 52 | the rules themselves. RITEMS should be banished. | |
| 53 | ||
| 54 | * src/output.c (output_token_translations): Rename as... | |
| 55 | (prepare_tokens): this. | |
| 56 | In addition to `translate', prepare the muscles `tname' and | |
| 57 | `toknum', which were handled by... | |
| 58 | (output_rule_data): this. | |
| 59 | Remove, and move the remainder of its outputs into... | |
| 60 | (prepare_rules): this new routines, which also merges content from | |
| 61 | (output_gram): this. | |
| 62 | (prepare_rules): Be sure never to walk through RITEMS. | |
| 63 | (output_stos): Rename as... | |
| 64 | (prepare_stos): this. | |
| 65 | (output): Always invoke prepare_states, after all, just don't use it | |
| 66 | in the output if you don't need it. | |

68 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 69 | ||
| 70 | * src/LR0.c (new_state): Display `nstates' as the name of the | |
| 71 | newly created state. | |
| 72 | Adjust to initialize first_state and last_state if needed. | |
| 73 | Be sure to distinguish the initial from the final state. | |
| 74 | (new_states): Create the itemset of the initial state, and use | |
| 75 | new_state. | |
| 76 | * src/closure.c (closure): Now that the initial state has its | |
| 77 | items properly set, there is no need for a special case when | |
| 78 | creating `ruleset'. | |
| 79 | ||
| 80 | As a result, now the rule 0, reducing to $axiom, is visible in the | |
| 81 | outputs. Adjust the test suite. | |
| 82 | ||
| 83 | * tests/conflicts.at (Solved SR Conflicts) | |
| 84 | (Unresolved SR Conflicts): Adjust. | |
| 85 | * tests/regression.at (Web2c Report, Rule Line Numbers): Idem. | |
| 86 | * tests/conflicts.at (S/R in initial): New. | |

| 89 | ||
| 90 | * src/LR0.c (allocate_itemsets): Don't loop over ritem: loop over | |
| 91 | the RHS of the rules. | |
| 92 | * src/output.c (output_gram): Likewise. | |
| 93 | ||
| bba97eb2 AD |
94 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 95 | ||
| 96 | * src/gram.h (rule_t): `lhs' is now a pointer to the symbol's | |
| 97 | bucket. | |
| 98 | Adjust all dependencies. | |
| 99 | * src/reduce.c (nonterminals_reduce): Don't forget to renumber the | |
| 100 | `number' of the buckets too. | |
| 101 | * src/gram.h: Include `symtab.h'. | |
| 102 | (associativity): Move to... | |
| 103 | * src/symtab.h: here. | |
| 104 | No longer include `gram.h'. | |
| 105 | ||

| c3b407f4 AD |
107 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 108 | ||
| 109 | * src/gram.h, src/gram.c (rules_rhs_length): New. | |
| 110 | (ritem_longest_rhs): Use it. | |
| 111 | * src/gram.h (rule_t): `number' is a new member. | |
| 112 | * src/reader.c (packgram): Set it. | |
| 113 | * src/reduce.c (reduce_grammar_tables): Move the useless rules at | |
| 114 | the end of `rules', and count them out of `nrules'. | |
| 115 | (reduce_output, dump_grammar): Adjust. | |
| 116 | * src/print.c (print_grammar): It is no longer needed to check for | |
| 117 | the usefulness of a rule, as useless rules are beyond `nrules + 1'. | |
| 118 | * tests/reduce.at (Reduced Automaton): New test. | |
| 119 | ||
| 11652ab3 AD |
120 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 121 | ||
| 122 | * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a | |
| 123 | lacking `+ 1' to nrules, Bison reported as useless a token if it | |
| 124 | was used solely to set the precedence of the last rule... | |
| 125 | ||
| 26b23c1a AD |
126 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 127 | ||

| 129 | name in #line, to avoid useless diffs between two identical | |
| 130 | outputs under different names. | |

| 422 | Remove the support for C++ namespace cleanliness; it was | |
| 423 | causing more problems than it was curing, since it didn't work | |
| 424 | properly on some nonstandard C++ compilers. This can wait | |

| 521 | that. | |

| 731 | tracing code to --trace, wait for a better --trace option, with | |
| 732 | args. | |
| 733 | ||
| 7ea5e977 AD |
734 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 735 | ||
| 736 | * src/bison.simple (YYSTDERR): Remove, replace `stderr'. | |
| 737 | The ISO C++ standard is extremely clear about it: stderr is | |
| 738 | considered a macro, not a regular symbol (see table 94 `Header | |
| 739 | <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files). | |
| 740 | Therefore std:: does not apply to it. It still does with fprintf. | |
| 741 | Also, s/cstdio.h/cstdio/. | |

743 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 744 | ||
| 745 | * lib/quotearg.c: Use `#include "..."' instead of `#include <...>' | |
| 746 | for non system headers. | |
| 747 | ||
| aed7fd9b AD |
748 | 2002-01-02 Akim Demaille <akim@epita.fr> |
| 749 | ||
| 750 | Equip the skeleton chain with location tracking, runtime trace, | |
| 751 | pure parser and scanner. | |
| 752 | ||
| 753 | * src/parse-skel.y: Request a pure parser, locations, and prefix | |
| 754 | renaming. | |
| 755 | (%union): Having several members with the same type does not help | |
| 756 | type mismatches, simplify. | |
| 757 | (YYPRINT, yyprint): New. | |
| 758 | (yyerror): ``Rename'' (there is a #define yyerror skel_error) as... | |
| 759 | (skel_error): this. | |
| 760 | Handle locations. | |
| 761 | * src/scan-skel.l: Adjust to these changes. | |
| 762 | * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP) | |
| 763 | (LOCATION_PRINT, skel_control_t): New. | |
| 764 | ||
| 24fad99e AD |
765 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 766 | ||
| 767 | * src/parse-skel.y: Get rid of the shift/reduce conflict: | |
| 768 | replace `gb' with BLANKS. | |
| 769 | * src/scan-skel.l: Adjust. | |
| 770 | ||
| a4b36db4 AD |
771 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 772 | ||
| 773 | * src/system.h: We don't need nor want bcopy. | |
| 774 | Throw away MS-DOS crap: we don't need getpid. | |
| 775 | * configure.in: We don't need strndup. It was even causing | |
| 776 | problems: because Flex includes the headers *before* us, | |
| 777 | _GNU_SOURCE is not defined by config.h, and therefore strndup was | |
| 778 | not visible. | |
| 779 | * lib/xstrndup.c: New. | |
| 780 | * src/scan-skel.l: Use it. | |
| 781 | Be sure to initialize yylval.muscle member when scanning a MUSCLE. | |
| 782 | * src/parse-skel.y: Use %directives instead of #defines. | |
| 783 | ||
| 1239777d AD |
784 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 785 | ||
| 786 | * src/skeleton.h: New. | |
| 787 | * src/output.c (output_parser, output_master_parser): Remove, dead | |
| 788 | code. | |
| 789 | * src/output.h (get_lines_number, actions_output, guards_output) | |
| 790 | (token_definitions_output): Prototype them. | |
| 791 | * src/parse-skel.y: Add the license notice. | |
| 792 | Include output.h and skeleton.h. | |
| 793 | (process_skeleton): Returns void, and takes a single parameter. | |
| 794 | * src/scan-skel.l: Add the license notice. | |
| 795 | Include skeleton.h. | |
| 796 | Don't use %option yylineno: it seems that then Flex imagines | |
| 797 | REJECT has been used, and therefore it won't reallocate its | |
| 798 | buffers (which makes no other sense to me than a bug). It results | |
| 799 | in warnings for `unused: yy_flex_realloc'. | |

| 802 | ||

| 805 | * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) | |
| 806 | (MUSCLE_INSERT_PREFIX): Move from here... | |
| 807 | ||
| 808 | * src/bison.hairy: Add a section directive. Put braces around muscle | |
| 809 | names. This parser skeleton is still broken, but Bison should not | |
| 810 | choke on a bad muscle 'syntax'. | |
| 811 | * src/bison.simple: Add a section directive. Put braces around muscle | |
| 812 | names. | |
| 813 | ||
| 814 | * src/files.h (strsuffix, stringappend): Add declarations. | |
| 815 | (tab_extension): Add declaration. | |
| 816 | (short_base_name): Add declaration. | |
| 817 | ||
| 818 | * src/files.c (strsuffix, stringappend): No longer static. These | |
| 819 | functions are used in the skeleton parser. | |
| 820 | (tab_extension): New. | |
| 821 | (compute_base_names): Use the computations done in this function | |
| fab5b110 | 822 | to guess if the generated parsers should have '.tab' in their |
| 9b3add5b RA |
823 | names. |
| 824 | (short_base_name): No longer static. | |
| 825 | ||
| 826 | * src/output.c (output_skeleton): New. | |
| 827 | (output): Disable call to output_master_parser, and give a try to | |
| 828 | a new skeleton handling system. | |
| 829 | (guards_output, actions_output): No longer static. | |
| 830 | (token_definitions_output, get_lines_number): No longer static. | |
| 831 | ||
| 832 | * configure.in: Use AM_PROG_LEX and AC_PROG_YACC. | |
| 833 | ||
| fab5b110 | 834 | * src/Makefile.am (bison_SOURCES): Add scan-skel.l and |
| 9b3add5b RA |
835 | parse-skel.y. |
| 836 | ||
| 837 | * src/parse-skel.y: New file. | |

| 841 | ||
| 842 | %name-prefix is broken. | |
| 843 | ||
| 844 | * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy". | |
| 845 | Adjust all dependencies. | |
| 846 | * tests/headers.at (export YYLTYPE): Strengthen this test: use | |
| 847 | %name-prefix. | |
| 848 | ||
| 849 | Renaming yylval but not yylloc is not consistent. Now we do. | |
| 850 | ||
| 851 | * src/bison.simple: Prefix yylloc if used. | |
| 852 | * doc/bison.texinfo (Decl Summary): Document that. | |

| 8c9a50be AD |
854 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 855 | ||
| 856 | * doc/bison.texinfo: Promote `%long-directive' over | |
| 857 | `%long_directive'. | |
| 858 | Remove all references to fixed-output-files, yacc is enough. | |
| 859 | ||
| d99361e6 AD |
860 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 861 | ||
| 862 | * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the | |
| 863 | user prologue. These are defaults. | |
| 864 | * tests/actions.at (Mid-rule actions): Make sure the user can | |
| 865 | define YYDEBUG and YYERROR_VERBOSE. | |

867 | 2001-12-29 Akim Demaille <akim@epita.fr> |

| 869 | * src/output.c (header_output): Don't forget to export YYLTYPE and | |
| 870 | yylloc. | |
| 871 | * tests/headers.at (export YYLTYPE): New, make sure it does. | |
| 872 | * tests/regression.at (%union and --defines, Invalid CPP headers): | |
| 873 | Move to... | |
| 874 | * tests/headers.at: here. | |

876 | 2001-12-29 Akim Demaille <akim@epita.fr> |

| 931394cb AD |
880 | 2001-12-29 Akim Demaille <akim@epita.fr> |

885 | 2001-12-29 Akim Demaille <akim@epita.fr> |

| 091e20bb AD |
889 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 890 | ||
| 891 | Don't store the token defs in a muscle, just be ready to output it | |
| 892 | on command. Now possible via `symbols'. Fixes a memory leak. | |
| 893 | ||
| 894 | * src/output.c (token_definitions_output): New. | |
| 895 | (output_parser, header_output): Use it. | |
| 896 | * src/reader.c (symbols_save): Remove. | |
| 897 | ||
| cce71710 AD |
898 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 899 | ||
| 900 | * src/bison.simple: Do not provide a default for YYSTYPE and | |
| 901 | YYLTYPE before the user's prologue. Otherwise it's hardly... a | |
| 902 | default. | |
| 903 | ||
| 82c035a8 AD |
904 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 905 | ||
| 906 | Mid-rule actions are simply... ignored! | |
| 907 | ||
| 908 | * src/reader.c (readgram): Be sure to attach mid-rule actions to | |
| 909 | the empty-rule associated to the dummy symbol, not to the host | |
| 910 | rule. | |
| 911 | * tests/actions.at (Mid-rule actions): New. | |

| 8419d367 AD |

| 920 | ||
| 921 | Memory leak. | |
| 922 | ||
| 923 | * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here, | |

| 925 | (allocate_storage): Do it here. | |

990 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 991 | ||
| 992 | * tests/regression.at (Web2c Actions): Blindly move the actual | |
| 993 | output as expected output. The contents *seem* right to me, but I | |
| 994 | can't pretend reading perfectly parser tables... Nonetheless, all | |
| 995 | the other tests pass correctly, the table look OK, even though the | |
| 996 | presence of `$axiom' is to be noted: AFAICS it is useless (but | |
| 997 | harmless). | |

| 1000 | ||
| 1001 | * src/reader.c (readgram): Don't add the rule 0 if there were no | |
| 1002 | rules read. In other words, add it _after_ having performed | |
| 1003 | grammar sanity checks. | |
| 1004 | Fixes the `tests/regression.at (Invalid input: 1)' Failure. | |

| 78d5bae9 AD |
1006 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 1007 | ||

| 610ab194 AD |
1018 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 1019 | ||
| 1020 | Fix the `GAWK Grammar' failure. | |
| 1021 | ||
| 1022 | * src/LR0.c (final_state): Initialize to -1 so that we do compute | |
| 1023 | the reductions of the first state which was mistakenly confused | |
| 1024 | with the final state because precisely final_state was initialized | |
| 1025 | to 0. | |
| 1026 | * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads, | |
| 1027 | now noticed by Bison. | |
| 1028 | * tests/regression.at (Rule Line Numbers): Adjust: state 0 does | |
| 1029 | have a reduction on $default. | |

1031 | 2001-12-29 Akim Demaille <akim@epita.fr> |

| 1036 | * src/derives.c (print_derives): Likewise. | |

| 1045 | are dumped. | |

1047 | 2001-12-29 Akim Demaille <akim@epita.fr> |

| 1074 | ||
| 1075 | * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special | |
| 1076 | cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and | |
| 1077 | Sparc, as they were causing more porting problems than the | |
| 1078 | (minor) performance improvement was worth. | |
| 1079 | ||
| 1080 | Also, catch up with 1.31's YYSTD. | |

| 3db472b9 AD |
1082 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 1083 | ||
| 1084 | * src/output.c (output_gram): Rely on nritems, not the | |
| 1085 | 0-sentinel. See below. | |
| 1086 | Use -1 as separator, not 0. | |
| 1087 | * src/bison.simple (yyparse): Subtract 1 to the rule numbers. | |
| 1088 | Rely on -1 as separator in yyrhs, instead of 0. | |
| 1089 | * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue | |
| 1090 | twice `Now at end of input', therefore there are two lines less to | |
| 1091 | expect. | |

| 1101 | * src/LR0.c (new_state): Recognize the final state by the fact it | |
| 1102 | is reached by eoftoken. | |
| 1103 | (insert_start_shifting_state, insert_eof_shifting_state) | |
| 1104 | (insert_accepting_state, augment_automaton): Remove, since now | |
| 1105 | these states are automatically computed from the initial state. | |
| 1106 | (generate_states): Adjust. | |
| 1107 | * src/print.c: When reporting a rule number to the user, substract | |
| 1108 | 1, so that the axiom rule is rule 0, and the first user rule is 1. | |
| 1109 | * src/reduce.c: Likewise. | |
| 1110 | * src/print_graph.c (print_core): For the time being, just as for | |
| 1111 | the report, depend upon --trace-flags to dump the full set of | |
| 1112 | items. | |
| 1113 | * src/reader.c (readgram): Once the grammar read, insert the rule | |
| 1114 | 0: `$axiom: START-SYMBOL $'. | |
| 1115 | * tests/set.at: Adjust: rule 0 is now displayed, and since the | |
| 1116 | number of the states has changed (the final state is no longer | |
| 1117 | necessarily the last), catch up. | |

| 1121 | Try to make the use of the eoftoken valid. Given that its value | |
| 1122 | is 0 which was also used as a sentinel in ritem, (i) make sure >= 0 | |
| 1123 | is used instead of > 0 where appropriate, (ii), depend upon nritems | |
| 1124 | instead of the 0-sentinel. | |
| 1125 | ||
| 1126 | * src/gram.h, src/gram.c (nritems): New. | |
| 1127 | Expected to be duplication of nitems, but for the time being... | |
| 1128 | * src/reader.c (packgram): Assert nritems and nitems are equal. | |
| 1129 | * src/LR0.c (allocate_itemsets, new_itemsets): Adjust. | |

| 1137 | * src/main.c (main): If there are complains after grammar | |
| 1138 | reductions, then output the report anyway if requested, then die. | |
| 1139 | * src/symtab.c (bucket_new): Initialize `value' to -1, not 0. | |
| 1140 | * src/reader.c (eoftoken): New. | |
| 1141 | (parse_token_decl): If the token being defined has value `0', it | |
| 1142 | is the eoftoken. | |
| 1143 | (packsymbols): No longer hack `tags' to insert `$' by hand. | |
| 1144 | Be sure to preserve the value of the eoftoken. | |
| 1145 | (reader): Make sure eoftoken is defined. | |
| 1146 | Initialize nsyms to 0: now eoftoken is created just like the others. | |
| 1147 | * src/print.c (print_grammar): Don't special case the eof token. | |
| 1148 | * src/regression.at: Adjust: `$' has value 0, not -1, which was a | |
| 1149 | lie anyway, albeit pleasant. | |
| 1150 | * tests/calc.at: Exercise error messages with eoftoken. | |
| 1151 | Change the grammar so that empty input is invalid. | |
| 1152 | Adjust expectations. | |
| 1153 | When yyungeting, be sure to use a valid yylloc: use last_yylloc. | |

| 1168 | * src/print_graph.c (print_state): Now errors are in red, and | |
| 1169 | reductions in green. | |

| 1229 | * src/reader.c (parse_braces): New, factoring... | |
| 1230 | (copy_action, copy_guard): these two which are renamed as... | |
| 1231 | (parse_action, parse_guard): these. | |

| 1239 | members. | |

| 1243 | the switch/case/break flesh. | |
| 1244 | Don't parse the user action that might follow the guard, let... | |
| 1245 | (readgram): do it, i.e., now, there can be an action after a | |
| 1246 | guard. | |
| 1247 | In other words the guard is just explicitly optional. | |

| 1253 | (output_files): Remove. | |
| 1254 | As a result, if one needs the former `.act' file, using an | |

| 1256 | required. | |
| 1257 | * src/main.c (main): Adjust. | |
| 1258 | * tests/semantic.at: New. | |
| 1259 | * tests/regression.at: Use `input.y' as input file name. | |

| 1261 | parser. | |

| 1290 | As much as possible, depend upon nlookaheads, instead of the | |
| 1291 | `lookaheadsp' member of the following state (since lookaheads of | |
| 1292 | successive states are successive, the difference between state n + 1 | |

| 1443 | Make `make distcheck' work. | |
| 1444 | ||
| 1445 | * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses | |
| 1446 | system.h which uses libgettext.h. | |

| 1449 | ||
| 1450 | * src/nullable.c (set_nullable): Useless rules must be skipped, | |
| 1451 | otherwise, since we range over their symbols, we might look at a | |
| 1452 | nonterminal which no longer ``exists'', i.e., it is not counted in | |
| 1453 | `nvars', hence we overflow our arrays. | |

| 1461 | (compute_header_macro): Global. | |
| 1462 | (defines_obstack_save): Remove. | |
| 1463 | * src/reader.c (parse_union_decl): No longer output to | |
| 1464 | defines_obstack: its content can be found in the `stype' muscle | |
| 1465 | anyway. | |
| 1466 | (output_token_translations): Merge into... | |

| 1475 | ||
| 1476 | * src/reader.c (parse_union_decl): Instead of handling two obstack | |
| 1477 | simultaneously, use one to define the `stype' muscle, and use the | |
| 1478 | value of the latter to fill defines_obstack. | |
| 1479 | (copy_comment): Remove. | |

| 1491 | Still making progress in separating Bison into (i) input, (ii) | |
| 1492 | process, (iii) output: now we can directly output the parser file | |
| 1493 | without using table_obstack at all. | |
| 1494 | ||
| 1495 | * src/files.c, src/files.h (table_obstack): Bye bye. | |
| 1496 | (parser_file_name): New. | |

| 1503 | Attach actions to rules, instead of pre-outputting them to | |
| 1504 | actions_obstack. | |
| 1505 | ||
| 1506 | * src/gram.h (rule_t): action and action_line are new members. | |
| 1507 | * src/reader.c (symbol_list): Likewise. | |
| 1508 | (copy_action): Save the actions within the rule. | |
| 1509 | (packgram): Save them in rule_table. | |
| 1510 | * src/output.c (actions_output): New. | |
| 1511 | (output_parser): Use it on `%%actions'. | |
| 1512 | (output_rule_data): Don't free rule_table. | |
| 1513 | (output): Do it. | |

1529 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 1530 | ||
| 1531 | * src/lex.c (literalchar): Don't escape the special characters, | |
| 1532 | just decode them, and keep them as char (before, eol was output as | |
| 1533 | the 2 char string `\n' etc.). | |
| 1534 | * src/output.c (output_rule_data): Use quotearg to output the | |
| 1535 | token strings. | |

| 1540 | Do not infringe on the global user namespace when using C++. | |
| 1541 | (YYFPRINTF, YYSTDERR): New macros, needed for the above. | |
| 1542 | All uses of `fprintf' and `stderr' changed. | |

| 1548 | The computation of nullable is broken: it doesn't handle empty | |
| 1549 | RHS's properly. | |
| 1550 | ||
| 1551 | * tests/torture.at (GNU AWK Grammar): New. | |
| 1552 | * tests/sets.at (Nullable): New. | |
| 1553 | * src/nullable.c (set_nullable): Instead of blindly looping over | |
| 1554 | `ritems', loop over the rules, and then over their rhs's. | |
| 1555 | ||
| 1556 | Work around Autotest bugs. | |
| 1557 | ||
| 1558 | * src/warshall.c (bitmatrix_print): Don't use `+--+' as table | |
| 1559 | frame, because Autotest understand lines starting with a `+' as | |
| 1560 | traces from the shell. Then, they are not processed properly. | |
| 1561 | Admittedly an Autotest bug, but we don't have time to wait for | |
| 1562 | Autotest to catch up. | |
| 1563 | * tests/regression.at (Broken Closure): Adjust to the new table | |
| 1564 | frames. | |
| 1565 | Move to... | |
| 1566 | * tests/sets.at: here. | |

1568 | 2001-12-13 Akim Demaille <akim@epita.fr> |

| 1571 | with BITS_PER_WORD. | |

1573 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 1574 | ||
| 1575 | * src/print.c (print_actions): Output the handling of `$' as the | |
| 1576 | traces do: shifting the token EOF. Before EOF was treated as a | |
| 1577 | nonterminal. | |
| 1578 | * tests/regression.at: Adjust some tests. | |
| 1579 | * src/print_graph.c (print_core): Complete the set of items via | |
| 1580 | closure. The next-to-final and final states are still unsatisfying, | |
| 1581 | but that's to be addressed elsewhere. | |
| 1582 | No longer output the rule numbers, but do output the state number. | |
| 1583 | A single loop for the shifts + gotos is enough, but picked a | |
| 1584 | distinct color for each. | |
| 1585 | (print_graph): Initialize and finalize closure. | |

1593 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 1594 | ||

| 1596 | on that of lib/error.c. | |
| 1597 | ||
| dbfb6dcd AD |
1598 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 1599 | ||
| 1600 | Some hosts don't like `/' in includes. | |
| 1601 | ||
| 1602 | * src/system.h: Include libgettext.h without qualifying the path. | |
| 1603 | * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove | |
| 1604 | $(top_srcdir). | |

| 1613 | is now handled in ... | |
| 1614 | * src/reader.c (read_additionnal_code): Add the output of a | |
| 1615 | #line for the epilogue. | |

1635 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 1636 | ||
| 1637 | * src/state.h (shifts): Remove the `number' member: shifts are | |
| 1638 | attached to state, hence no longer need to be labelled with a | |
| 1639 | state number. | |
| 1640 | ||
| 190c4f5f AD |
1641 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 1642 | ||
| 1643 | Now that states have a complete set of members, the linked list of | |
| 1644 | shifts is useless: just fill directly the state's shifts member. | |
| 1645 | ||
| 1646 | * src/state.h (shifts): Remove the `next' member. | |
| 1647 | * src/LR0.c (first_state, last_state): Remove. | |
| 1648 | Adjust the callers. | |
| 1649 | (augment_automaton): Don't look for the shifts that must be added | |
| 1650 | a shift on EOF: it is those of the state we looked for! But now, | |
| 1651 | since shifts are attached, it is no longer needed to looking | |
| 1652 | merely by its id: its number. | |

1654 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 1655 | ||
| 1656 | * src/LR0.c (augment_automaton): Better variable locality. | |
| 1657 | Remove an impossible branch: if there is a state corresponding to | |
| 1658 | the start symbol being shifted, then there is shift for the start | |
| 1659 | symbol from the initial state. | |
| 1660 | ||

1661 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 1662 | ||
| 1663 | * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state' | |
| 1664 | only when appropriate: when insert_start_shifting_state' is not | |
| 1665 | invoked. | |
| 1666 | * tests/regression.at (Rule Line Numbers): Adjust. | |

| 1682 | ||
| 1683 | * src/LR0.h (first_shift, first_reduction): Remove. | |

1687 | 2001-12-10 Akim Demaille <akim@epita.fr> |

| 1698 | (insert_eof_shifting_state, insert_accepting_state): New. | |
| 1699 | (augment_automaton): Adjust. | |
| 1700 | Better locality of the variables. | |
| 1701 | When looking if the start_symbol is shifted from the initial | |
| 1702 | state, using `while (... symbol != start_symbol ...)' sounds | |
| 1703 | better than `while (... symbol < start_symbol ...)': If fail | |
| 1704 | to see how the order between symbols could be relevant! | |

1706 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 1707 | ||
| 1708 | * src/getargs.h: Don't declare `spec_name_prefix' and | |

1716 | 2001-12-10 Akim Demaille <akim@epita.fr> |
