| 900c877b AD |
1510 | Note: this patch partially drops `semantic-parser' support: it |

| 1666 | * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the | |

| 1669 | This makes it easier to check for several error messages. | |

| 1687 | hard coded 2. | |
| 1688 | (Even though this 2 is not the same as above: the number of the | |
| 1689 | undeftoken remains being 2, it is its user token number which | |
| 1690 | might not be 2). | |
| 1691 | * src/output.c (prepare_tokens): Rename the `maxtok' muscle with | |
| 1692 | `user_token_number_max'. | |
| 1693 | Output `undef_token_number'. | |
| 1694 | * data/bison.simple, data/bison.c++: Use them. | |
| 1695 | Be sure to map invalid yylex return values to | |

| 1732 | ||
| 1733 | Trying with bigger grammars shows various phenomena: at 3000 (28Mb | |
| 1734 | of grammar file) bison is killed by my system, at 2000 (12Mb) bison | |
| 1735 | passes, but produces negative #line number, once fixed, GCC is | |
| 1736 | killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of | |

| 1932 | * src/print.c (print_grammar): It is no longer needed to check for | |
| 1933 | the usefulness of a rule, as useless rules are beyond `nrules + 1'. | |
| 1934 | * tests/reduce.at (Reduced Automaton): New test. | |

| 11652ab3 AD |
1936 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 1937 | ||
| 1938 | * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a | |
| 1939 | lacking `+ 1' to nrules, Bison reported as useless a token if it | |
| 1940 | was used solely to set the precedence of the last rule... | |
| 1941 | ||

| 2469 | (section.yacc): Remove. | |
| 2470 | (prefix): Remove too. | |
| 2471 | * src/scan-skel.l: Adjust. | |

| 2476 | * configure.in (WERROR_CFLAGS): Compute it. | |
| 2477 | * src/Makefile.am (CFLAGS): Pass it. | |
| 2478 | * tests/atlocal.in (CFLAGS): Idem. | |
| 2479 | * src/files.c: Fix a few warnings. | |

| 2483 | ||
| 2484 | * src/getargs.c (AS_FILE_NAME): New. | |
| 2485 | (getargs): Use it to convert DOSish file names. | |
| 2486 | * src/files.c (base_name): Rename as full_base_name to avoid | |
| 2487 | clashes with `base_name ()'. | |
| 2488 | (filename_split): New. | |
| 2489 | (compute_base_names): N-th rewrite, using filename_split. | |

| 2492 | ||
| 2493 | * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c: | |
| 2494 | New, stolen from the Fileutils 4.1. | |
| 2495 | * lib/Makefile.am (libbison_a_SOURCES): Adjust. | |
| 2496 | * configure.in: Check for the presence of memrchr, and of its | |
| 2497 | prototype. | |

2499 | 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be> |
| 2500 | ||
| 2501 | * lib/hash.h (__P): Added definition for this macro. | |
| 2502 | * src/Makefile.am: Add parse-skel.c and scan-skel.c to | |
| 2503 | BUILT_SOURCES, to ensure they are generated first. | |
| 2504 | * src/parse-skel.y: Use YYERROR_VERBOSE instead of | |
| 2505 | %error-verbose to allow bootstrapping with bison 1.30x. | |
| 2506 | ||
| 2b25d624 AD |
2507 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 2508 | ||
| 2509 | * src/reader.c (parse_braces): Don't fetch the next char, the | |
| 2510 | convention is to fetch on entry. | |
| 2511 | * tests/torture.at (GNU Cim Grammar): Reintroduce their weird | |
| 2512 | 'switch' without a following semicolon. | |
| 2513 | * tests/regression.at (braces parsing): New. | |
| 2514 | ||
| 3460813b AD |
2515 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 2516 | ||
| 2517 | Bison is dead wrong in its RR conflict reports. | |
| 2518 | ||
| 2519 | * tests/torture.at (GNU Cim Grammar): New. | |
| 2520 | * src/conflicts.c (count_rr_conflicts): Fix. | |

2522 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 2523 | ||
| 2524 | Creating package.m4 from configure.ac causes too many problems. | |
| 2525 | ||
| 2526 | * tests/Makefile.am (package.m4): Create it by hand, | |
| 2527 | AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf. | |
| 2528 | ||
| 25d81090 AD |
2529 | 2002-01-06 Akim Demaille <akim@epita.fr> |

2534 | 2002-01-04 Paul Eggert <eggert@twinsun.com> |
| 2535 | ||
| 2536 | * doc/bison.texinfo (Debugging): | |
| 2537 | Remove YYSTDERR; it's no longer defined or used. | |
| 2538 | Also, s/cstdio.h/cstdio/. | |
| 2539 | ||
| 25d81090 AD |
2540 | 2002-01-03 Akim Demaille <akim@epita.fr> |

2544 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 2545 | ||
| 2546 | * src/parse-skel.y (process_skeleton): Don't bind the parser's | |
| 2547 | tracing code to --trace, wait for a better --trace option, with | |
| 2548 | args. | |
| 2549 | ||
| 7ea5e977 AD |
2550 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 2551 | ||
| 2552 | * src/bison.simple (YYSTDERR): Remove, replace `stderr'. | |
| 2553 | The ISO C++ standard is extremely clear about it: stderr is | |
| 2554 | considered a macro, not a regular symbol (see table 94 `Header | |
| 2555 | <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files). | |
| 2556 | Therefore std:: does not apply to it. It still does with fprintf. | |
| 2557 | Also, s/cstdio.h/cstdio/. | |

2559 | 2002-01-03 Akim Demaille <akim@epita.fr> |

| 2562 | for non system headers. | |
| 2563 | ||
| aed7fd9b AD |
2564 | 2002-01-02 Akim Demaille <akim@epita.fr> |
| 2565 | ||
| 2566 | Equip the skeleton chain with location tracking, runtime trace, | |
| 2567 | pure parser and scanner. | |
| 2568 | ||
| 2569 | * src/parse-skel.y: Request a pure parser, locations, and prefix | |
| 2570 | renaming. | |
| 2571 | (%union): Having several members with the same type does not help | |
| 2572 | type mismatches, simplify. | |
| 2573 | (YYPRINT, yyprint): New. | |
| 2574 | (yyerror): ``Rename'' (there is a #define yyerror skel_error) as... | |
| 2575 | (skel_error): this. | |
| 2576 | Handle locations. | |
| 2577 | * src/scan-skel.l: Adjust to these changes. | |
| 2578 | * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP) | |
| 2579 | (LOCATION_PRINT, skel_control_t): New. | |

2581 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 2582 | ||
| 2583 | * src/parse-skel.y: Get rid of the shift/reduce conflict: | |
| 2584 | replace `gb' with BLANKS. | |
| 2585 | * src/scan-skel.l: Adjust. | |
| 2586 | ||
| a4b36db4 AD |
2587 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 2588 | ||
| 2589 | * src/system.h: We don't need nor want bcopy. | |
| 2590 | Throw away MS-DOS crap: we don't need getpid. | |
| 2591 | * configure.in: We don't need strndup. It was even causing | |
| 2592 | problems: because Flex includes the headers *before* us, | |
| 2593 | _GNU_SOURCE is not defined by config.h, and therefore strndup was | |
| 2594 | not visible. | |
| 2595 | * lib/xstrndup.c: New. | |
| 2596 | * src/scan-skel.l: Use it. | |
| 2597 | Be sure to initialize yylval.muscle member when scanning a MUSCLE. | |
| 2598 | * src/parse-skel.y: Use %directives instead of #defines. | |
| 2599 | ||

| 2602 | * src/skeleton.h: New. | |
| 2603 | * src/output.c (output_parser, output_master_parser): Remove, dead | |
| 2604 | code. | |
| 2605 | * src/output.h (get_lines_number, actions_output, guards_output) | |
| 2606 | (token_definitions_output): Prototype them. | |
| 2607 | * src/parse-skel.y: Add the license notice. | |
| 2608 | Include output.h and skeleton.h. | |
| 2609 | (process_skeleton): Returns void, and takes a single parameter. | |
| 2610 | * src/scan-skel.l: Add the license notice. | |
| 2611 | Include skeleton.h. | |
| 2612 | Don't use %option yylineno: it seems that then Flex imagines | |
| 2613 | REJECT has been used, and therefore it won't reallocate its | |
| 2614 | buffers (which makes no other sense to me than a bug). It results | |
| 2615 | in warnings for `unused: yy_flex_realloc'. | |

| 2618 | ||

| 2622 | (MUSCLE_INSERT_PREFIX): Move from here... | |
| 2623 | ||
| 2624 | * src/bison.hairy: Add a section directive. Put braces around muscle | |
| 2625 | names. This parser skeleton is still broken, but Bison should not | |
| 2626 | choke on a bad muscle 'syntax'. | |
| 2627 | * src/bison.simple: Add a section directive. Put braces around muscle | |
| 2628 | names. | |
| 2629 | ||
| 2630 | * src/files.h (strsuffix, stringappend): Add declarations. | |
| 2631 | (tab_extension): Add declaration. | |
| 2632 | (short_base_name): Add declaration. | |
| 2633 | ||
| 2634 | * src/files.c (strsuffix, stringappend): No longer static. These | |
| 2635 | functions are used in the skeleton parser. | |
| 2636 | (tab_extension): New. | |
| 2637 | (compute_base_names): Use the computations done in this function | |
| fab5b110 | 2638 | to guess if the generated parsers should have '.tab' in their |
| 9b3add5b RA |
2639 | names. |
| 2640 | (short_base_name): No longer static. | |
| 2641 | ||
| 2642 | * src/output.c (output_skeleton): New. | |
| 2643 | (output): Disable call to output_master_parser, and give a try to | |
| 2644 | a new skeleton handling system. | |
| 2645 | (guards_output, actions_output): No longer static. | |
| 2646 | (token_definitions_output, get_lines_number): No longer static. | |
| 2647 | ||
| 2648 | * configure.in: Use AM_PROG_LEX and AC_PROG_YACC. | |
| 2649 | ||
| fab5b110 | 2650 | * src/Makefile.am (bison_SOURCES): Add scan-skel.l and |
| 9b3add5b RA |
2651 | parse-skel.y. |
| 2652 | ||
| 2653 | * src/parse-skel.y: New file. | |

| 2658 | %name-prefix is broken. | |

| 2660 | * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy". | |
| 2661 | Adjust all dependencies. | |
| 2662 | * tests/headers.at (export YYLTYPE): Strengthen this test: use | |
| 2663 | %name-prefix. | |
| 2664 | ||
| 2665 | Renaming yylval but not yylloc is not consistent. Now we do. | |
| 2666 | ||
| 2667 | * src/bison.simple: Prefix yylloc if used. | |
| 2668 | * doc/bison.texinfo (Decl Summary): Document that. | |

| 8c9a50be AD |
2670 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 2671 | ||
| 2672 | * doc/bison.texinfo: Promote `%long-directive' over | |

| 2674 | Remove all references to fixed-output-files, yacc is enough. | |
| 2675 | ||
| d99361e6 AD |
2676 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 2677 | ||
| 2678 | * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the | |
| 2679 | user prologue. These are defaults. | |
| 2680 | * tests/actions.at (Mid-rule actions): Make sure the user can | |
| 2681 | define YYDEBUG and YYERROR_VERBOSE. | |
| 2682 | ||
| b9cecb91 AD |
2683 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 2684 | ||
| 2685 | * src/output.c (header_output): Don't forget to export YYLTYPE and | |
| 2686 | yylloc. | |
| 2687 | * tests/headers.at (export YYLTYPE): New, make sure it does. | |
| 2688 | * tests/regression.at (%union and --defines, Invalid CPP headers): | |
| 2689 | Move to... | |
| 2690 | * tests/headers.at: here. | |

| 931394cb AD |
2696 | 2001-12-29 Akim Demaille <akim@epita.fr> |

2701 | 2001-12-29 Akim Demaille <akim@epita.fr> |

2705 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 2706 | ||
| 2707 | Don't store the token defs in a muscle, just be ready to output it | |
| 2708 | on command. Now possible via `symbols'. Fixes a memory leak. | |
| 2709 | ||
| 2710 | * src/output.c (token_definitions_output): New. | |

2714 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 2715 | ||
| 2716 | * src/bison.simple: Do not provide a default for YYSTYPE and | |
| 2717 | YYLTYPE before the user's prologue. Otherwise it's hardly... a | |
| 2718 | default. | |
| 2719 | ||

2720 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 2721 | ||
| 2722 | Mid-rule actions are simply... ignored! | |
| 2723 | ||
| 2724 | * src/reader.c (readgram): Be sure to attach mid-rule actions to | |
| 2725 | the empty-rule associated to the dummy symbol, not to the host | |
| 2726 | rule. | |
| 2727 | * tests/actions.at (Mid-rule actions): New. | |

2735 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 2736 | ||
| 2737 | Memory leak. | |
| 2738 | ||
| 2739 | * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here, | |
| 2740 | since it allocates it for each state, although only one is needed. | |
| 2741 | (allocate_storage): Do it here. | |

2806 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 2807 | ||
| 2808 | * tests/regression.at (Web2c Actions): Blindly move the actual | |
| 2809 | output as expected output. The contents *seem* right to me, but I | |
| 2810 | can't pretend reading perfectly parser tables... Nonetheless, all | |
| 2811 | the other tests pass correctly, the table look OK, even though the | |
| 2812 | presence of `$axiom' is to be noted: AFAICS it is useless (but | |

| 2817 | * src/reader.c (readgram): Don't add the rule 0 if there were no | |
| 2818 | rules read. In other words, add it _after_ having performed | |
| 2819 | grammar sanity checks. | |
| 2820 | Fixes the `tests/regression.at (Invalid input: 1)' Failure. | |

| 2836 | Fix the `GAWK Grammar' failure. | |
| 2837 | ||
| 2838 | * src/LR0.c (final_state): Initialize to -1 so that we do compute | |
| 2839 | the reductions of the first state which was mistakenly confused | |
| 2840 | with the final state because precisely final_state was initialized | |
| 2841 | to 0. | |
| 2842 | * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads, | |
| 2843 | now noticed by Bison. | |

| 2890 | ||
| 2891 | * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special | |
| 2892 | cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and | |
| 2893 | Sparc, as they were causing more porting problems than the | |
| 2894 | (minor) performance improvement was worth. | |

| 3db472b9 AD |
2898 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 2899 | ||
| 2900 | * src/output.c (output_gram): Rely on nritems, not the | |
| 2901 | 0-sentinel. See below. | |
| 2902 | Use -1 as separator, not 0. | |
| 2903 | * src/bison.simple (yyparse): Subtract 1 to the rule numbers. | |
| 2904 | Rely on -1 as separator in yyrhs, instead of 0. | |
| 2905 | * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue | |
| 2906 | twice `Now at end of input', therefore there are two lines less to | |
| 2907 | expect. | |

| 2916 | ||
| 2917 | * src/LR0.c (new_state): Recognize the final state by the fact it | |
| 2918 | is reached by eoftoken. | |
| 2919 | (insert_start_shifting_state, insert_eof_shifting_state) | |
| 2920 | (insert_accepting_state, augment_automaton): Remove, since now | |
| 2921 | these states are automatically computed from the initial state. | |
| 2922 | (generate_states): Adjust. | |
| 2923 | * src/print.c: When reporting a rule number to the user, substract | |
| 2924 | 1, so that the axiom rule is rule 0, and the first user rule is 1. | |
| 2925 | * src/reduce.c: Likewise. | |
| 2926 | * src/print_graph.c (print_core): For the time being, just as for | |
| 2927 | the report, depend upon --trace-flags to dump the full set of | |
| 2928 | items. | |
| 2929 | * src/reader.c (readgram): Once the grammar read, insert the rule | |
| 2930 | 0: `$axiom: START-SYMBOL $'. | |
| 2931 | * tests/set.at: Adjust: rule 0 is now displayed, and since the | |
| 2932 | number of the states has changed (the final state is no longer | |
| 2933 | necessarily the last), catch up. | |

| 2937 | Try to make the use of the eoftoken valid. Given that its value | |
| 2938 | is 0 which was also used as a sentinel in ritem, (i) make sure >= 0 | |
| 2939 | is used instead of > 0 where appropriate, (ii), depend upon nritems | |
| 2940 | instead of the 0-sentinel. | |
| 2941 | ||
| 2942 | * src/gram.h, src/gram.c (nritems): New. | |
| 2943 | Expected to be duplication of nitems, but for the time being... | |
| 2944 | * src/reader.c (packgram): Assert nritems and nitems are equal. | |
| 2945 | * src/LR0.c (allocate_itemsets, new_itemsets): Adjust. | |

2951 | 2001-12-27 Akim Demaille <akim@epita.fr> |

| 2953 | * src/main.c (main): If there are complains after grammar | |
| 2954 | reductions, then output the report anyway if requested, then die. | |
| 2955 | * src/symtab.c (bucket_new): Initialize `value' to -1, not 0. | |
| 2956 | * src/reader.c (eoftoken): New. | |
| 2957 | (parse_token_decl): If the token being defined has value `0', it | |
| 2958 | is the eoftoken. | |
| 2959 | (packsymbols): No longer hack `tags' to insert `$' by hand. | |
| 2960 | Be sure to preserve the value of the eoftoken. | |
| 2961 | (reader): Make sure eoftoken is defined. | |
| 2962 | Initialize nsyms to 0: now eoftoken is created just like the others. | |
| 2963 | * src/print.c (print_grammar): Don't special case the eof token. | |
| 2964 | * src/regression.at: Adjust: `$' has value 0, not -1, which was a | |
| 2965 | lie anyway, albeit pleasant. | |
| 2966 | * tests/calc.at: Exercise error messages with eoftoken. | |
| 2967 | Change the grammar so that empty input is invalid. | |
| 2968 | Adjust expectations. | |
| 2969 | When yyungeting, be sure to use a valid yylloc: use last_yylloc. | |

| 2984 | * src/print_graph.c (print_state): Now errors are in red, and | |

| 3061 | (readgram): do it, i.e., now, there can be an action after a | |
| 3062 | guard. | |
| 3063 | In other words the guard is just explicitly optional. | |

| 3068 | * src/files.c, src/files.h (obstack_save): Remove. | |
| 3069 | (output_files): Remove. | |
| 3070 | As a result, if one needs the former `.act' file, using an | |

| 3072 | required. | |

| 3086 | All the hacks using a final pseudo state are now useless. | |
| 3087 | ||
| 3088 | * src/LR0.c (set_state_table): state_table holds exactly nstates. | |
| 3089 | * src/lalr.c (nLA): New. | |
| 3090 | (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it | |

| 3106 | As much as possible, depend upon nlookaheads, instead of the | |
| 3107 | `lookaheadsp' member of the following state (since lookaheads of | |

| 3174 | * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that | |
| 3175 | YYDEBUG must be defined to a nonzero value. | |
| 3176 | ||
| 3177 | * src/bison.simple (yytname): Do not assume that the user defines | |

3180 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 3181 | ||
| 3182 | * src/state.h (state_t): Rename lookaheads as lookaheadsp. | |
| 3183 | nlookaheads is a new member. | |
| 3184 | Adjust all users. | |
| 3185 | * src/lalr.h (nlookaheads): Remove this orphan declaration. | |

| 3191 | * src/files.h, src/files.c (open_files, close_files): Remove. | |
| 3192 | * src/main.c (main): Don't open/close files, nor invoke lex_free, | |
| 3193 | let... | |

| f87685c3 AD |
3206 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 3207 | ||
| 3208 | * src/output.c (output_obstack): Be static and rename as... | |
| 3209 | (format_obstack): this, to avoid any confusion with files.c's | |
| 3210 | output_obstack. | |
| 3211 | * src/reader.h (muscle_obstack): Move to... | |
| 3212 | * src/output.h: here, since it's defined in output.c. | |

| 3225 | ||
| 3226 | * src/files.c (output_files): Free the output_obstack. | |

3232 | 2001-12-16 Marc Autret <autret_m@epita.fr> |
| 3233 | ||
| 3234 | * src/output.c (actions_output): Fix. When we use %no-lines, | |
| 3235 | there is one less line per action. | |
| 3236 | ||

3237 | 2001-12-16 Marc Autret <autret_m@epita.fr> |
| 3238 | ||
| 3239 | * src/bison.simple: Remove a useless #line directive. | |
| 3240 | s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'. | |
| 3241 | * src/output.c (get_lines_number): New. | |
| 776209d6 | 3242 | (output_parser): Adjust, now takes care about the lines of a |

3243 | output muscles. |

| 3245 | (actions_output): Computes the number of lines taken by actions. | |

| 1a4648ff AD |
3257 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 3258 | ||
| 3259 | Make `make distcheck' work. | |
| 3260 | ||
| 3261 | * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses | |
| 3262 | system.h which uses libgettext.h. | |
| 3263 | ||
| 9c2c67e6 AD |
3264 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 3265 | ||
| 3266 | * src/nullable.c (set_nullable): Useless rules must be skipped, | |
| 3267 | otherwise, since we range over their symbols, we might look at a | |
| 3268 | nonterminal which no longer ``exists'', i.e., it is not counted in | |
| 3269 | `nvars', hence we overflow our arrays. | |

| 3273 | The header can also be produced directly, without any obstack! | |
| 3274 | Yahoo! | |

| 3277 | (compute_header_macro): Global. | |
| 3278 | (defines_obstack_save): Remove. | |
| 3279 | * src/reader.c (parse_union_decl): No longer output to | |
| 3280 | defines_obstack: its content can be found in the `stype' muscle | |
| 3281 | anyway. | |
| 3282 | (output_token_translations): Merge into... | |
| 3283 | (symbols_output): this. | |
| 3284 | Rename as... | |

3290 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 3291 | ||
| 3292 | * src/reader.c (parse_union_decl): Instead of handling two obstack | |
| 3293 | simultaneously, use one to define the `stype' muscle, and use the | |
| 3294 | value of the latter to fill defines_obstack. | |
| 3295 | (copy_comment): Remove. | |
| 3296 | (copy_comment2): Work for a single obstack. | |
| 3297 | Rename as... | |

| 3306 | ||
| 3307 | Still making progress in separating Bison into (i) input, (ii) | |
| 3308 | process, (iii) output: now we can directly output the parser file | |
| 3309 | without using table_obstack at all. | |
| 3310 | ||
| 3311 | * src/files.c, src/files.h (table_obstack): Bye bye. | |
| 3312 | (parser_file_name): New. | |
| 3313 | * src/files.c (compute_output_file_names): Compute it. | |
| 3314 | * src/output.c (actions_output, output_parser) | |
| 3315 | (output_master_parser): To a file instead of an obstack. | |

| 3f96f4dc AD |
3317 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 3318 | ||
| 3319 | Attach actions to rules, instead of pre-outputting them to | |
| 3320 | actions_obstack. | |
| 3321 | ||
| 3322 | * src/gram.h (rule_t): action and action_line are new members. | |
| 3323 | * src/reader.c (symbol_list): Likewise. | |
| 3324 | (copy_action): Save the actions within the rule. | |
| 3325 | (packgram): Save them in rule_table. | |
| 3326 | * src/output.c (actions_output): New. | |
| 3327 | (output_parser): Use it on `%%actions'. | |
| 3328 | (output_rule_data): Don't free rule_table. | |
| 3329 | (output): Do it. | |
| 3330 | (prepare): Don't save the `action' muscle. | |
| 3331 | * src/bison.simple: s/%%action/%%actions/. | |

| 51576fb3 AD |
3333 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 3334 | ||
| 3335 | * src/reader.c (copy_action): When --yacc, don't append a `;' | |
| 3336 | to the user action: let it fail if lacking. | |
| dee049eb | 3337 | Suggested by Arnold Robbins and Tom Tromey. |

3339 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 3340 | ||
| 3341 | * src/lex.c (literalchar): Simply return the char you decoded, non | |
| 3342 | longer mess around with obstacks and int pointers. | |
| 3343 | Adjust all callers. | |
| 3344 | ||
| 92790e5b AD |
3345 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 3346 | ||
| 3347 | * src/lex.c (literalchar): Don't escape the special characters, | |
| 3348 | just decode them, and keep them as char (before, eol was output as | |
| 3349 | the 2 char string `\n' etc.). | |
| 3350 | * src/output.c (output_rule_data): Use quotearg to output the | |
| 3351 | token strings. | |

3353 | 2001-12-13 Paul Eggert <eggert@twinsun.com> |
| 3354 | ||
| 3355 | * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE): | |
| 3356 | Do not infringe on the global user namespace when using C++. | |
| 3357 | (YYFPRINTF, YYSTDERR): New macros, needed for the above. | |
| 3358 | All uses of `fprintf' and `stderr' changed. | |
| 3359 | ||
| 3360 | * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR. | |

| 3363 | ||
| 3364 | The computation of nullable is broken: it doesn't handle empty | |
| 3365 | RHS's properly. | |
| 3366 | ||
| 3367 | * tests/torture.at (GNU AWK Grammar): New. | |
| 3368 | * tests/sets.at (Nullable): New. | |
| 3369 | * src/nullable.c (set_nullable): Instead of blindly looping over | |
| 3370 | `ritems', loop over the rules, and then over their rhs's. | |
| 3371 | ||
| 3372 | Work around Autotest bugs. | |
| 3373 | ||
| 3374 | * src/warshall.c (bitmatrix_print): Don't use `+--+' as table | |
| 3375 | frame, because Autotest understand lines starting with a `+' as | |
| 3376 | traces from the shell. Then, they are not processed properly. | |
| 3377 | Admittedly an Autotest bug, but we don't have time to wait for | |
| 3378 | Autotest to catch up. | |
| 3379 | * tests/regression.at (Broken Closure): Adjust to the new table | |
| 3380 | frames. | |
| 3381 | Move to... | |
| 3382 | * tests/sets.at: here. | |
| 3383 | ||
| cb581495 AD |
3384 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 3385 | ||
| 3386 | * src/closure.c (closure): Use nrules instead of playing tricks | |
| 3387 | with BITS_PER_WORD. | |
| 3388 | ||
| 2e729273 AD |
3389 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 3390 | ||
| 3391 | * src/print.c (print_actions): Output the handling of `$' as the | |
| 3392 | traces do: shifting the token EOF. Before EOF was treated as a | |
| 3393 | nonterminal. | |
| 3394 | * tests/regression.at: Adjust some tests. | |
| 3395 | * src/print_graph.c (print_core): Complete the set of items via | |
| 3396 | closure. The next-to-final and final states are still unsatisfying, | |
| 3397 | but that's to be addressed elsewhere. | |
| 3398 | No longer output the rule numbers, but do output the state number. | |
| 3399 | A single loop for the shifts + gotos is enough, but picked a | |
| 3400 | distinct color for each. | |
| 3401 | (print_graph): Initialize and finalize closure. | |
| 3402 | ||
| 107f7dfb AD |
3403 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 3404 | ||
| 3405 | * src/reader.c (readgram): Remove dead code, an strip useless | |
| 3406 | braces. | |
| 3407 | (get_type): Remove, unused. | |
| 3408 | ||
| 9b53a24f AD |
3409 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 3410 | ||
| 3411 | * src/complain.h, src/complain.c: Remove error_one_per_line, rely | |
| 3412 | on that of lib/error.c. | |
| 3413 | ||
| dbfb6dcd AD |
3414 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 3415 | ||
| 3416 | Some hosts don't like `/' in includes. | |
| 3417 | ||
| 3418 | * src/system.h: Include libgettext.h without qualifying the path. | |
| 3419 | * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove | |
| 3420 | $(top_srcdir). | |
| 3421 | ||

3422 | 2001-12-11 Marc Autret <autret_m@epita.fr> |

3426 | 2001-12-11 Marc Autret <autret_m@epita.fr> |
| 3427 | ||
| 3428 | * src/bison.simple: Remove #line just before %%epilogue. It | |
| 3429 | is now handled in ... | |
| 3430 | * src/reader.c (read_additionnal_code): Add the output of a | |
| 3431 | #line for the epilogue. | |
| 3432 | ||
| e83d80b8 MA |
3433 | 2001-12-10 Marc Autret <autret_m@epita.fr> |
| 3434 | ||
| 927c1557 | 3435 | * src/reader.c (copy_definition): Re-use CPP-outed code which |
| e83d80b8 MA |
3436 | replace precedent remove. |
| 3437 | * src/bison.simple: Remove #line before %%prologue because | |
| 3438 | %%input-line is wrong at this time. | |
| 3439 | ||
| 971d5158 MA |
3440 | 2001-12-10 Marc Autret <autret_m@epita.fr> |
| 3441 | ||
| 3442 | * src/reader.c (symbols_output): Clean up. | |
| 927c1557 | 3443 | * src/output.c (output_gram, output): Clean up. |

3445 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3446 | ||
| 3447 | * src/lalr.c (initialize_lookaheads): New. Extracted from... | |

| 3449 | * src/lalr.c (lalr): Call it. | |
| 3450 | ||

3451 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3452 | ||
| 3453 | * src/state.h (shifts): Remove the `number' member: shifts are | |
| 3454 | attached to state, hence no longer need to be labelled with a | |
| 3455 | state number. | |
| 3456 | ||
| 190c4f5f AD |
3457 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3458 | ||
| 3459 | Now that states have a complete set of members, the linked list of | |
| 3460 | shifts is useless: just fill directly the state's shifts member. | |
| 3461 | ||
| 3462 | * src/state.h (shifts): Remove the `next' member. | |
| 3463 | * src/LR0.c (first_state, last_state): Remove. | |
| 3464 | Adjust the callers. | |
| 3465 | (augment_automaton): Don't look for the shifts that must be added | |
| 3466 | a shift on EOF: it is those of the state we looked for! But now, | |
| 3467 | since shifts are attached, it is no longer needed to looking | |
| 3468 | merely by its id: its number. | |
| 3469 | ||
| 2a73b93d AD |
3470 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3471 | ||
| 3472 | * src/LR0.c (augment_automaton): Better variable locality. | |
| 3473 | Remove an impossible branch: if there is a state corresponding to | |
| 3474 | the start symbol being shifted, then there is shift for the start | |
| 3475 | symbol from the initial state. | |
| 3476 | ||
| 74392f6a AD |
3477 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3478 | ||
| 3479 | * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state' | |
| 3480 | only when appropriate: when insert_start_shifting_state' is not | |
| 3481 | invoked. | |
| 3482 | * tests/regression.at (Rule Line Numbers): Adjust. | |
| 3483 | ||
| 37c82725 AD |
3484 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3485 | ||
| 3486 | * src/LR0.c (augment_automaton): Now that all states have shifts, | |
| 3487 | merge the two cases addition shifts to the initial state. | |
| 3488 | ||
| 6a164e0c AD |
3489 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3490 | ||

| 3492 | * src/LR0.c: here. | |
| 3493 | * src/lalr.c (lalr): Don't call it... | |
| 3494 | * src/LR0.c (generate_states): do it. | |
| 3495 | * src/LR0.h (first_state): Remove, only the table is used. | |
| 3496 | ||
| 7215de24 AD |
3497 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3498 | ||
| 3499 | * src/LR0.h (first_shift, first_reduction): Remove. | |
| 3500 | * src/lalr.c: Don't use first_shift: find shifts through the | |
| 3501 | states. | |
| 3502 | ||
| 80e25d4d AD |
3503 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 3504 | ||
| 3505 | * src/LR0.c: Attach shifts to states as soon as they are | |
| 3506 | computed. | |
| 3507 | * src/lalr.c (set_state_table): Instead of assigning shifts to | |
| 3508 | state, just assert that the mapping was properly done. | |

| 0ab3728b AD |
3510 | 2001-12-10 Akim Demaille <akim@epita.fr> |

| 3513 | (insert_start_shifting_state): this. | |
| 3514 | (insert_eof_shifting_state, insert_accepting_state): New. | |
| 3515 | (augment_automaton): Adjust. | |
| 3516 | Better locality of the variables. | |
| 3517 | When looking if the start_symbol is shifted from the initial | |
| 3518 | state, using `while (... symbol != start_symbol ...)' sounds | |
| 3519 | better than `while (... symbol < start_symbol ...)': If fail | |
| 3520 | to see how the order between symbols could be relevant! | |

| 3524 | * src/getargs.h: Don't declare `spec_name_prefix' and | |
| 3525 | `spec_file_prefix', declared by src/files.h. | |
| 3526 | * src/files.c, src/files.h: Default for spec_name_prefix is "yy". | |
| 3527 | * src/muscle_tab.c (muscle_init): Default prefix to NULL. | |
| 3528 | * src/output.c (prepare): Adjust. | |
| 3529 | * src/reader.c (symbols_output): Likewise. | |
| 3530 | * src/vmsgetargs.c: Vaguely adjust, but who cares? | |

| 3534 | * src/muscle_tab.c (muscle_init): NULL is a better default than | |
| 3535 | `"0"'. | |

| 3543 | Now that states have a complete set of members, the linked list of | |
| 3544 | reductions is useless: just fill directly the state's reductions | |
| 3545 | member. | |
| 3546 | ||
| 3547 | * src/state.h (struct reductions): Remove member `number' and | |
| 3548 | `next'. | |
| 3549 | * src/LR0.c (first_reduction, last_reduction): Remove. | |
| 3550 | (save_reductions): Don't link the new reductions, store them in | |
| 3551 | this_state. | |
| 3552 | * src/lalr.c (set_state_table): No need to attach reductions to | |
| 3553 | states, it's already done. | |
| 3554 | * src/output.c (output_actions): No longer free the shifts, then | |
| 3555 | the reductions, then the states: free all the states and their | |
| 3556 | members. | |

| 3562 | ||
| 0edad749 AD |
3563 | * src/muscle_tab.c: Don't include xalloc.h and string.h: that's |
| 3564 | the job of system.h. | |
| 3565 | * src/options.c: Don't include stdio.h and xalloc.h for the same | |
| 3566 | reasons. | |

| 3575 | Clean up GCC warnings. | |
| 3576 | ||
| 3577 | * src/reader.c (copy_action): `buf' is not used. | |
| 3578 | (parse_skel_decl): Be static. | |
| 3579 | * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'. | |
| 3580 | * src/options.h (create_long_option_table): Have a real prototype. | |
| 3581 | * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete) | |
| 3582 | (hash_delete_at): Return const void *. | |
| 3583 | Adjust casts to preserve the const. | |

| 3594 | One structure for states is enough, even though theoretically | |
| 3595 | there are LR(0) states and LALR(1) states. | |
| 3596 | ||
| 3597 | * src/lalr.h (state_t): Remove. | |
| 3598 | (state_table): Be state_t **, not state_t *. | |
| 3599 | * src/state.h (core, CORE_ALLOC): Rename as... | |
| 3600 | (state_t, STATE_ALLOC): this. | |
| 3601 | Add the LALR(1) members: shifts, reductions, errs. | |
| 3602 | * src/LR0.c (state_table): Rename as... | |
| 3603 | (state_hash): this, to avoid name clashes with the global | |
| 3604 | `state_table'. | |
| 3605 | * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c | |
| 3606 | * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust. | |

| 3613 | * src/warshall.c (bitmatrix_print): New. | |
| 3614 | (TC): Use it. | |
| 3615 | When performing a transitive closure R(i, j) && R(j, k) => R(i, k), | |
