2084 (prepare): Given that for the time being changesyntax is not
2085 usable in M4, rename the muscles using `-' to `_'.

2123 Fix `%nonassoc and eof'.

2151 2002-01-24 Akim Demaille <akim@epita.fr>
2153 Bison dumps core when trying to complain about broken input files.
2154 Reported by Cris van Pelt.
2156 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
2157 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
2159 (Invalid inputs): Strengthen: exercise parse_percent_token.
2161 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
2163 * src/Makefile.am: Add bison.c++.
2164 * src/bison.c++: New skeleton.
2166 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
2170 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
2172 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
2174 2002-01-20 Marc Autret <marc@gnu.org>
2176 * src/files.c (compute_output_file_names): Fix
2178 2002-01-20 Marc Autret <marc@gnu.org>
2180 * tests/output.at: New test.
2181 * src/files.c (compute_base_names): Don't map extensions when
2182 the YACC flag is set, use defaults.
2183 Reported by Evgeny Stambulchik.
2185 2002-01-20 Marc Autret <marc@gnu.org>
2187 * src/system.h: Need to define __attribute__ away for non-GCC
2188 compilers as well (i.e. the vendor C compiler).
2189 Suggested by Albert Chin-A-Young.
2191 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
2193 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
2194 canonical definition.
2195 * src/system.h: Use the canonical definition for PARAMS (avoids
2196 a conflict with the macro from lib/hash.h).
2198 2002-01-11 Akim Demaille <akim@epita.fr>
2200 * configure.in: Use AC_FUNC_STRNLEN.
2201 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
2203 2002-01-09 Akim Demaille <akim@epita.fr>
2205 * src/files.c, src/files.h (output_infix): New.
2206 (tab_extension): Remove.
2207 (compute_base_names): Compute the former, drop the latter.
2208 * src/output.c (prepare): Insert the muscles `output-infix', and
2210 * src/parse-skel.y (string, string.1): New.
2211 (section.header): Use it.
2212 (section.yacc): Remove.
2213 (prefix): Remove too.
2214 * src/scan-skel.l: Adjust.
2215 * src/bison.simple, src/bison.hairy: Adjust.
2217 2002-01-09 Akim Demaille <akim@epita.fr>
2219 * configure.in (WERROR_CFLAGS): Compute it.
2220 * src/Makefile.am (CFLAGS): Pass it.
2221 * tests/atlocal.in (CFLAGS): Idem.
2222 * src/files.c: Fix a few warnings.
2223 (get_extension_index): Remove, unused.
2225 2002-01-08 Akim Demaille <akim@epita.fr>
2227 * src/getargs.c (AS_FILE_NAME): New.
2228 (getargs): Use it to convert DOSish file names.
2229 * src/files.c (base_name): Rename as full_base_name to avoid
2230 clashes with `base_name ()'.
2231 (filename_split): New.
2232 (compute_base_names): N-th rewrite, using filename_split.
2234 2002-01-08 Akim Demaille <akim@epita.fr>
2236 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
2237 New, stolen from the Fileutils 4.1.
2238 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
2239 * configure.in: Check for the presence of memrchr, and of its
2242 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
2244 * lib/hash.h (__P): Added definition for this macro.
2245 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
2246 BUILT_SOURCES, to ensure they are generated first.
2247 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
2248 %error-verbose to allow bootstrapping with bison 1.30x.
2250 2002-01-06 Akim Demaille <akim@epita.fr>
2252 * src/reader.c (parse_braces): Don't fetch the next char, the
2253 convention is to fetch on entry.
2254 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
2255 'switch' without a following semicolon.
2256 * tests/regression.at (braces parsing): New.
2258 2002-01-06 Akim Demaille <akim@epita.fr>
2260 Bison is dead wrong in its RR conflict reports.
2262 * tests/torture.at (GNU Cim Grammar): New.
2263 * src/conflicts.c (count_rr_conflicts): Fix.
2265 2002-01-06 Akim Demaille <akim@epita.fr>
2267 Creating package.m4 from configure.ac causes too many problems.
2269 * tests/Makefile.am (package.m4): Create it by hand,
2270 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
2272 2002-01-06 Akim Demaille <akim@epita.fr>
2274 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
2277 2002-01-04 Paul Eggert <eggert@twinsun.com>
2279 * doc/bison.texinfo (Debugging):
2280 Remove YYSTDERR; it's no longer defined or used.
2281 Also, s/cstdio.h/cstdio/.
2283 2002-01-03 Akim Demaille <akim@epita.fr>
2285 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
2287 2002-01-03 Akim Demaille <akim@epita.fr>
2289 * src/parse-skel.y (process_skeleton): Don't bind the parser's
2290 tracing code to --trace, wait for a better --trace option, with
2293 2002-01-03 Akim Demaille <akim@epita.fr>
2295 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
2296 The ISO C++ standard is extremely clear about it: stderr is
2297 considered a macro, not a regular symbol (see table 94 `Header
2298 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
2299 Therefore std:: does not apply to it. It still does with fprintf.
2300 Also, s/cstdio.h/cstdio/.
2302 2002-01-03 Akim Demaille <akim@epita.fr>
2304 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
2305 for non system headers.
2307 2002-01-02 Akim Demaille <akim@epita.fr>
2309 Equip the skeleton chain with location tracking, runtime trace,
2310 pure parser and scanner.
2312 * src/parse-skel.y: Request a pure parser, locations, and prefix
2314 (%union): Having several members with the same type does not help
2315 type mismatches, simplify.
2316 (YYPRINT, yyprint): New.
2317 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
2320 * src/scan-skel.l: Adjust to these changes.
2321 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
2322 (LOCATION_PRINT, skel_control_t): New.
2324 2001-12-30 Akim Demaille <akim@epita.fr>
2326 * src/parse-skel.y: Get rid of the shift/reduce conflict:
2327 replace `gb' with BLANKS.
2328 * src/scan-skel.l: Adjust.
2330 2001-12-30 Akim Demaille <akim@epita.fr>
2332 * src/system.h: We don't need nor want bcopy.
2333 Throw away MS-DOS crap: we don't need getpid.
2334 * configure.in: We don't need strndup. It was even causing
2335 problems: because Flex includes the headers *before* us,
2336 _GNU_SOURCE is not defined by config.h, and therefore strndup was
2338 * lib/xstrndup.c: New.
2339 * src/scan-skel.l: Use it.
2340 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
2341 * src/parse-skel.y: Use %directives instead of #defines.
2343 2001-12-30 Akim Demaille <akim@epita.fr>
2345 * src/skeleton.h: New.
2346 * src/output.c (output_parser, output_master_parser): Remove, dead
2348 * src/output.h (get_lines_number, actions_output, guards_output)
2349 (token_definitions_output): Prototype them.
2350 * src/parse-skel.y: Add the license notice.
2351 Include output.h and skeleton.h.
2352 (process_skeleton): Returns void, and takes a single parameter.
2353 * src/scan-skel.l: Add the license notice.
2355 Don't use %option yylineno: it seems that then Flex imagines
2356 REJECT has been used, and therefore it won't reallocate its
2357 buffers (which makes no other sense to me than a bug). It results
2358 in warnings for `unused: yy_flex_realloc'.
2360 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
2362 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2363 (MUSCLE_INSERT_PREFIX): ...to there.
2364 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2365 (MUSCLE_INSERT_PREFIX): Move from here...
2367 * src/bison.hairy: Add a section directive. Put braces around muscle
2368 names. This parser skeleton is still broken, but Bison should not
2369 choke on a bad muscle 'syntax'.
2370 * src/bison.simple: Add a section directive. Put braces around muscle
2373 * src/files.h (strsuffix, stringappend): Add declarations.
2374 (tab_extension): Add declaration.
2375 (short_base_name): Add declaration.
2377 * src/files.c (strsuffix, stringappend): No longer static. These
2378 functions are used in the skeleton parser.
2379 (tab_extension): New.
2380 (compute_base_names): Use the computations done in this function
2381 to guess if the generated parsers should have '.tab' in their
2383 (short_base_name): No longer static.
2385 * src/output.c (output_skeleton): New.
2386 (output): Disable call to output_master_parser, and give a try to
2387 a new skeleton handling system.
2388 (guards_output, actions_output): No longer static.
2389 (token_definitions_output, get_lines_number): No longer static.
2391 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
2393 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
2396 * src/parse-skel.y: New file.
2397 * src/scan-skel.l: New file.
2399 2001-12-29 Akim Demaille <akim@epita.fr>
2401 %name-prefix is broken.
2403 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
2404 Adjust all dependencies.
2405 * tests/headers.at (export YYLTYPE): Strengthen this test: use
2408 Renaming yylval but not yylloc is not consistent. Now we do.
2410 * src/bison.simple: Prefix yylloc if used.
2411 * doc/bison.texinfo (Decl Summary): Document that.
2413 2001-12-29 Akim Demaille <akim@epita.fr>
2415 * doc/bison.texinfo: Promote `%long-directive' over
2417 Remove all references to fixed-output-files, yacc is enough.
2419 2001-12-29 Akim Demaille <akim@epita.fr>
2421 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
2422 user prologue. These are defaults.
2423 * tests/actions.at (Mid-rule actions): Make sure the user can
2424 define YYDEBUG and YYERROR_VERBOSE.
2426 2001-12-29 Akim Demaille <akim@epita.fr>
2428 * src/output.c (header_output): Don't forget to export YYLTYPE and
2430 * tests/headers.at (export YYLTYPE): New, make sure it does.
2431 * tests/regression.at (%union and --defines, Invalid CPP headers):
2433 * tests/headers.at: here.
2435 2001-12-29 Akim Demaille <akim@epita.fr>
2437 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
2439 2001-12-29 Akim Demaille <akim@epita.fr>
2441 * tests/actions.at (Mid-rule actions): Output on a single line
2444 2001-12-29 Akim Demaille <akim@epita.fr>
2446 * doc/bison.texinfo: Formatting changes.
2448 2001-12-29 Akim Demaille <akim@epita.fr>
2450 Don't store the token defs in a muscle, just be ready to output it
2451 on command. Now possible via `symbols'. Fixes a memory leak.
2453 * src/output.c (token_definitions_output): New.
2454 (output_parser, header_output): Use it.
2455 * src/reader.c (symbols_save): Remove.
2457 2001-12-29 Akim Demaille <akim@epita.fr>
2459 * src/bison.simple: Do not provide a default for YYSTYPE and
2460 YYLTYPE before the user's prologue. Otherwise it's hardly... a
2463 2001-12-29 Akim Demaille <akim@epita.fr>
2465 Mid-rule actions are simply... ignored!
2467 * src/reader.c (readgram): Be sure to attach mid-rule actions to
2468 the empty-rule associated to the dummy symbol, not to the host
2470 * tests/actions.at (Mid-rule actions): New.
2472 2001-12-29 Akim Demaille <akim@epita.fr>
2476 * src/reader.c (reader): Free grammar.
2478 2001-12-29 Akim Demaille <akim@epita.fr>
2482 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
2483 since it allocates it for each state, although only one is needed.
2484 (allocate_storage): Do it here.
2486 2001-12-29 Akim Demaille <akim@epita.fr>
2488 * src/options.h, src/options.c (create_long_option_table): Rename
2490 (long_option_table_new): this, with a clearer prototype.
2491 (percent_table): Remove, unused,
2492 * src/getargs.c (getargs): Adjust.
2494 2001-12-29 Akim Demaille <akim@epita.fr>
2496 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
2497 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
2500 2001-12-29 Akim Demaille <akim@epita.fr>
2502 * src/lalr.c (build_relations): Rename `states' as `states1'.
2503 Sorry, I don't understand exactly what it is, no better name...
2505 2001-12-29 Akim Demaille <akim@epita.fr>
2507 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
2508 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
2509 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
2512 2001-12-29 Akim Demaille <akim@epita.fr>
2514 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
2517 2001-12-29 Akim Demaille <akim@epita.fr>
2519 * src/reader.c, src/reader.h (user_toknums): Remove.
2520 Adjust all users to use symbols[i]->user_token_number.
2522 2001-12-29 Akim Demaille <akim@epita.fr>
2524 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
2525 Adjust all users to use symbols[i]->prec or ->assoc.
2527 2001-12-29 Akim Demaille <akim@epita.fr>
2529 * src/reader.c, src/reader.h (tags): Remove.
2530 Adjust all users to use symbols[i]->tag.
2532 2001-12-29 Akim Demaille <akim@epita.fr>
2534 * src/gram.h, src/gram.c (symbols): New, similar to state_table
2536 * src/reader.c (packsymbols): Fill this table.
2538 * src/conflicts.c (resolve_sr_conflict): Adjust.
2539 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
2541 Use symbols[i]->tag instead of tags[i].
2543 2001-12-29 Akim Demaille <akim@epita.fr>
2545 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
2546 In addition, put a comment in there, to replace...
2547 * tests/regression.at (%union and C comments): Remove.
2549 2001-12-29 Akim Demaille <akim@epita.fr>
2551 * tests/regression.at (Web2c Actions): Blindly move the actual
2552 output as expected output. The contents *seem* right to me, but I
2553 can't pretend reading perfectly parser tables... Nonetheless, all
2554 the other tests pass correctly, the table look OK, even though the
2555 presence of `$axiom' is to be noted: AFAICS it is useless (but
2558 2001-12-29 Akim Demaille <akim@epita.fr>
2560 * src/reader.c (readgram): Don't add the rule 0 if there were no
2561 rules read. In other words, add it _after_ having performed
2562 grammar sanity checks.
2563 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
2565 2001-12-29 Akim Demaille <akim@epita.fr>
2567 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
2568 visible, and some states have now a different number.
2570 2001-12-29 Akim Demaille <akim@epita.fr>
2572 * src/reader.c (readgram): Bind the initial rule's lineno to that
2574 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
2575 (Solved SR Conflicts): Adjust rule 0's line number.
2577 2001-12-29 Akim Demaille <akim@epita.fr>
2579 Fix the `GAWK Grammar' failure.
2581 * src/LR0.c (final_state): Initialize to -1 so that we do compute
2582 the reductions of the first state which was mistakenly confused
2583 with the final state because precisely final_state was initialized
2585 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
2586 now noticed by Bison.
2587 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
2588 have a reduction on $default.
2590 2001-12-29 Akim Demaille <akim@epita.fr>
2592 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
2594 * src/closure.c (print_closure): Likewise.
2595 * src/derives.c (print_derives): Likewise.
2596 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
2599 2001-12-29 Akim Demaille <akim@epita.fr>
2601 * src/lalr.c (lookaheads_print): New.
2602 (lalr): Call it when --trace-flag.
2603 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
2606 2001-12-29 Akim Demaille <akim@epita.fr>
2608 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
2609 when walking through ritem, even via rule->rhs.
2610 * src/reduce.c (dump_grammar, useful_production, reduce_output)
2611 (useful_production, useless_nonterminals): Likewise.
2612 (reduce_grammar_tables): Likewise, plus update nritems.
2613 * src/nullable.c (set_nullable): Likewise.
2614 * src/lalr.c (build_relations): Likewise.
2615 * tests/sets.at (Nullable): Adjust.
2616 Fortunately, now, the $axiom is no longer nullable.
2618 2001-12-29 Akim Demaille <akim@epita.fr>
2620 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
2622 * src/gram.c (ritem_longest_rhs): Likewise.
2623 * src/reduce.c (nonterminals_reduce): Likewise.
2624 * src/print_graph.c (print_graph): Likewise.
2625 * src/output.c (output_rule_data): Likewise.
2626 * src/nullable.c (set_nullable): Likewise.
2628 2001-12-29 Akim Demaille <akim@epita.fr>
2630 * src/output.c: Comment changes.
2632 2001-12-27 Paul Eggert <eggert@twinsun.com>
2634 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
2635 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
2636 Sparc, as they were causing more porting problems than the
2637 (minor) performance improvement was worth.
2639 Also, catch up with 1.31's YYSTD.
2641 2001-12-27 Akim Demaille <akim@epita.fr>
2643 * src/output.c (output_gram): Rely on nritems, not the
2644 0-sentinel. See below.
2645 Use -1 as separator, not 0.
2646 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
2647 Rely on -1 as separator in yyrhs, instead of 0.
2648 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
2649 twice `Now at end of input', therefore there are two lines less to
2652 2001-12-27 Akim Demaille <akim@epita.fr>
2654 * tests/regression.at (Unresolved SR Conflicts):
2655 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
2658 2001-12-27 Akim Demaille <akim@epita.fr>
2660 * src/LR0.c (new_state): Recognize the final state by the fact it
2661 is reached by eoftoken.
2662 (insert_start_shifting_state, insert_eof_shifting_state)
2663 (insert_accepting_state, augment_automaton): Remove, since now
2664 these states are automatically computed from the initial state.
2665 (generate_states): Adjust.
2666 * src/print.c: When reporting a rule number to the user, substract
2667 1, so that the axiom rule is rule 0, and the first user rule is 1.
2668 * src/reduce.c: Likewise.
2669 * src/print_graph.c (print_core): For the time being, just as for
2670 the report, depend upon --trace-flags to dump the full set of
2672 * src/reader.c (readgram): Once the grammar read, insert the rule
2673 0: `$axiom: START-SYMBOL $'.
2674 * tests/set.at: Adjust: rule 0 is now displayed, and since the
2675 number of the states has changed (the final state is no longer
2676 necessarily the last), catch up.
2678 2001-12-27 Akim Demaille <akim@epita.fr>
2680 Try to make the use of the eoftoken valid. Given that its value
2681 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
2682 is used instead of > 0 where appropriate, (ii), depend upon nritems
2683 instead of the 0-sentinel.
2685 * src/gram.h, src/gram.c (nritems): New.
2686 Expected to be duplication of nitems, but for the time being...
2687 * src/reader.c (packgram): Assert nritems and nitems are equal.
2688 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
2689 * src/closure.c (print_closure, print_fderives): Likewise.
2690 * src/gram.c (ritem_print): Likewise.
2691 * src/print.c (print_core, print_grammar): Likewise.
2692 * src/print_graph.c: Likewise.
2694 2001-12-27 Akim Demaille <akim@epita.fr>
2696 * src/main.c (main): If there are complains after grammar
2697 reductions, then output the report anyway if requested, then die.
2698 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
2699 * src/reader.c (eoftoken): New.
2700 (parse_token_decl): If the token being defined has value `0', it
2702 (packsymbols): No longer hack `tags' to insert `$' by hand.
2703 Be sure to preserve the value of the eoftoken.
2704 (reader): Make sure eoftoken is defined.
2705 Initialize nsyms to 0: now eoftoken is created just like the others.
2706 * src/print.c (print_grammar): Don't special case the eof token.
2707 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
2708 lie anyway, albeit pleasant.
2709 * tests/calc.at: Exercise error messages with eoftoken.
2710 Change the grammar so that empty input is invalid.
2711 Adjust expectations.
2712 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
2714 2001-12-27 Akim Demaille <akim@epita.fr>
2716 * configure.in: Check the protos of strchr ans strspn.
2717 Replace strchr if needed.
2718 * src/system.h: Provide the protos of strchr, strspn and memchr if
2720 * lib/strchr.c: New.
2721 * src/reader.c (symbols_save): Use strchr.
2723 2001-12-27 Akim Demaille <akim@epita.fr>
2725 * src/print.c, src/print_graph.c (escape): New.
2726 Use it to quote the TAGS outputs.
2727 * src/print_graph.c (print_state): Now errors are in red, and
2728 reductions in green.
2729 Prefer high to wide: output the state number on a line of its own.
2731 2001-12-27 Akim Demaille <akim@epita.fr>
2733 * src/state.h, src/state.c (reductions_new): New.

2754 2001-12-27 Akim Demaille <akim@epita.fr>
2756 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
2757 * src/print.c: here.
2758 (lookaheadset, shiftset): New, used as additional storage by
2760 (print_results): Adjust.
2761 (print_shifts, print_gotos, print_errs): New, extracted from...
2762 (print_actions): here.
2763 * src/print_graph.c (print_actions): Remove dead code.
2765 2001-12-27 Akim Demaille <akim@epita.fr>
2767 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
2770 2001-12-27 Akim Demaille <akim@epita.fr>
2772 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

2786 * src/files.c, src/files.h (guard_obstack): Remove.
2787 * src/output.c (output): Adjust.
2788 * src/reader.c (parse_braces): New, factoring...
2789 (copy_action, copy_guard): these two which are renamed as...
2790 (parse_action, parse_guard): these.
2791 As a voluntary consequence, using braces around guards is now
2794 2001-12-27 Akim Demaille <akim@epita.fr>
2796 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
2797 * src/reader.c (symbol_list): `guard' and `guard_line' are new
2799 (symbol_list_new): Adjust.
2800 (copy_action): action_line is the first line, not the last.
2801 (copy_guard): Just as for actions, store the `action' only, not
2802 the switch/case/break flesh.
2803 Don't parse the user action that might follow the guard, let...
2804 (readgram): do it, i.e., now, there can be an action after a
2806 In other words the guard is just explicitly optional.
2808 * src/output.c (guards_output): New.
2809 (output_parser): Call it when needed.
2810 (output): Also free the guard and attrs obstacks.
2811 * src/files.c, src/files.h (obstack_save): Remove.
2812 (output_files): Remove.
2813 As a result, if one needs the former `.act' file, using an
2814 appropriate skeleton which requires actions and guards is now
2816 * src/main.c (main): Adjust.
2817 * tests/semantic.at: New.
2818 * tests/regression.at: Use `input.y' as input file name.
2819 Avoid 8+3 problems by requiring input.c when the test needs the
2822 2001-12-27 Akim Demaille <akim@epita.fr>
2824 * src/reader.c (symbol_list_new): Be sure to initialize all the
2827 2001-12-27 Akim Demaille <akim@epita.fr>
2829 All the hacks using a final pseudo state are now useless.
2831 * src/LR0.c (set_state_table): state_table holds exactly nstates.
2832 * src/lalr.c (nLA): New.
2833 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
2834 instead of lookaheadsp from the pseudo state (nstate + 1).
2836 2001-12-27 Akim Demaille <akim@epita.fr>
2838 * src/output.c (action_row, token_actions): Use a state_t instead
2839 of a integer, and nlookaheads instead of the following state's

2844 * src/conflicts.c (log_resolution, flush_shift)
2845 (resolve_sr_conflict, set_conflicts, solve_conflicts)
2846 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
2847 (conflicts_print, print_reductions): Use a state_t instead of an
2848 integer when referring to a state.
2849 As much as possible, depend upon nlookaheads, instead of the
2850 `lookaheadsp' member of the following state (since lookaheads of
2851 successive states are successive, the difference between state n + 1
2852 and n served as the number of lookaheads for state n).
2853 * src/lalr.c (add_lookback_edge): Likewise.
2854 * src/print.c (print_core, print_actions, print_state)
2855 (print_results): Likewise.

2862 * src/bison.hairy: Formatting/comment changes.
2864 Remove `register' indications.
2865 Add plenty of `static'.

2869 * src/output.c (prepare): Drop the muscle `ntbase' which
2871 * src/bison.simple: Formatting/comment changes.
2872 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
2873 is an undocumented synonym.
2875 2001-12-22 Akim Demaille <akim@epita.fr>
2877 * src/output.c (output_table_data): Change the prototype to use
2878 `int' for array ranges: some invocations do pass an int, not a
2880 Reported by Wayne Green.
2882 2001-12-22 Akim Demaille <akim@epita.fr>
2884 Some actions of web2c.y are improperly triggered.
2885 Reported by Mike Castle.
2887 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

2889 (Web2c Report): this.
2890 (Web2c Actions): New.
2892 2001-12-22 Akim Demaille <akim@epita.fr>

2900 2001-12-18 Akim Demaille <akim@epita.fr>
2902 Some host fail on `assert (!"foo")', which expands to
2903 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
2904 Reported by Nelson Beebee.
2906 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
2907 `#define it_succeeded 0' and `assert (it_succeeded)'.
2909 2001-12-17 Marc Autret <autret_m@epita.fr>
2911 * src/bison.simple: Don't hard code the skeleton line and filename.
2912 * src/output.c (output_parser): Rename 'line' as 'output_line'.
2913 New line counter 'skeleton_line' (skeleton-line muscle).
2915 2001-12-17 Paul Eggert <eggert@twinsun.com>
2917 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
2918 YYDEBUG must be defined to a nonzero value.
2920 * src/bison.simple (yytname): Do not assume that the user defines
2921 YYDEBUG to a properly parenthesized expression.
2923 2001-12-17 Akim Demaille <akim@epita.fr>
2925 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
2926 nlookaheads is a new member.
2928 * src/lalr.h (nlookaheads): Remove this orphan declaration.
2929 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
2932 2001-12-17 Akim Demaille <akim@epita.fr>
2934 * src/files.h, src/files.c (open_files, close_files): Remove.
2935 * src/main.c (main): Don't open/close files, nor invoke lex_free,
2937 * src/reader.c (reader): Do it.
2939 2001-12-17 Akim Demaille <akim@epita.fr>
2941 * src/conflicts.c (print_reductions): Formatting changes.
2943 2001-12-17 Akim Demaille <akim@epita.fr>
2945 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
2946 (flush_reduce): New.
2947 (resolve_sr_conflict): Adjust.
2949 2001-12-17 Akim Demaille <akim@epita.fr>
2951 * src/output.c (output_obstack): Be static and rename as...
2952 (format_obstack): this, to avoid any confusion with files.c's
2954 * src/reader.h (muscle_obstack): Move to...
2955 * src/output.h: here, since it's defined in output.c.
2957 2001-12-17 Akim Demaille <akim@epita.fr>
2959 * src/output.c (action_row, save_column, default_goto)
2960 (sort_actions, matching_state, pack_vector): Better variable
2963 2001-12-17 Akim Demaille <akim@epita.fr>
2965 * src/output.c: Various formatting changes.
2967 2001-12-17 Akim Demaille <akim@epita.fr>
2969 * src/files.c (output_files): Free the output_obstack.
2970 * src/main.c (main): Call print and print_graph conditionally.
2971 * src/print.c (print): Work unconditionally.
2972 * src/print_graph.c (print_graph): Work unconditionally.
2973 * src/conflicts.c (log_resolution): Output only if verbose_flag.
2975 2001-12-16 Marc Autret <autret_m@epita.fr>
2977 * src/output.c (actions_output): Fix. When we use %no-lines,
2978 there is one less line per action.
2980 2001-12-16 Marc Autret <autret_m@epita.fr>
2982 * src/bison.simple: Remove a useless #line directive.
2983 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
2984 * src/output.c (get_lines_number): New.
2985 (output_parser): Adjust, now takes care about the lines of a
2988 (actions_output): Computes the number of lines taken by actions.
2989 (output_master_parser): Insert new skeleton which is the name of
2990 the output parser file name.
2992 2001-12-15 Marc Autret <autret_m@epita.fr>
2994 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
2996 2001-12-15 Marc Autret <autret_m@epita.fr>
2998 * src/output.c (output_gram): Keep track of the hairy one.
3000 2001-12-15 Akim Demaille <akim@epita.fr>
3002 Make `make distcheck' work.
3004 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3005 system.h which uses libgettext.h.
3007 2001-12-15 Akim Demaille <akim@epita.fr>
3009 * src/nullable.c (set_nullable): Useless rules must be skipped,
3010 otherwise, since we range over their symbols, we might look at a
3011 nonterminal which no longer ``exists'', i.e., it is not counted in
3012 `nvars', hence we overflow our arrays.
3014 2001-12-15 Akim Demaille <akim@epita.fr>
3016 The header can also be produced directly, without any obstack!
3019 * src/files.c, src/files.h (defines_obstack): Remove.
3020 (compute_header_macro): Global.
3021 (defines_obstack_save): Remove.
3022 * src/reader.c (parse_union_decl): No longer output to
3023 defines_obstack: its content can be found in the `stype' muscle
3025 (output_token_translations): Merge into...
3026 (symbols_output): this.
3028 (symbols_save): this.
3030 * src/output.c (header_output): New.
3033 2001-12-15 Akim Demaille <akim@epita.fr>
3035 * src/reader.c (parse_union_decl): Instead of handling two obstack
3036 simultaneously, use one to define the `stype' muscle, and use the
3037 value of the latter to fill defines_obstack.
3038 (copy_comment): Remove.
3039 (copy_comment2): Work for a single obstack.
3041 (copy_comment): this.
3043 2001-12-15 Akim Demaille <akim@epita.fr>
3045 * src/lex.c, src/lex.h (xgetc): No longer static.
3046 * src/reader.c (parse_union_decl): Revamp.
3048 2001-12-15 Akim Demaille <akim@epita.fr>
3050 Still making progress in separating Bison into (i) input, (ii)
3051 process, (iii) output: now we can directly output the parser file
3052 without using table_obstack at all.
3054 * src/files.c, src/files.h (table_obstack): Bye bye.
3055 (parser_file_name): New.
3056 * src/files.c (compute_output_file_names): Compute it.
3057 * src/output.c (actions_output, output_parser)
3058 (output_master_parser): To a file instead of an obstack.
3060 2001-12-15 Akim Demaille <akim@epita.fr>
3062 Attach actions to rules, instead of pre-outputting them to
3065 * src/gram.h (rule_t): action and action_line are new members.
3066 * src/reader.c (symbol_list): Likewise.
3067 (copy_action): Save the actions within the rule.
3068 (packgram): Save them in rule_table.
3069 * src/output.c (actions_output): New.
3070 (output_parser): Use it on `%%actions'.
3071 (output_rule_data): Don't free rule_table.
3073 (prepare): Don't save the `action' muscle.
3074 * src/bison.simple: s/%%action/%%actions/.
3076 2001-12-15 Akim Demaille <akim@epita.fr>
3078 * src/reader.c (copy_action): When --yacc, don't append a `;'
3079 to the user action: let it fail if lacking.
3080 Suggested by Arnold Robbins and Tom Tromey.
3082 2001-12-14 Akim Demaille <akim@epita.fr>
3084 * src/lex.c (literalchar): Simply return the char you decoded, non
3085 longer mess around with obstacks and int pointers.
3088 2001-12-14 Akim Demaille <akim@epita.fr>
3090 * src/lex.c (literalchar): Don't escape the special characters,
3091 just decode them, and keep them as char (before, eol was output as
3092 the 2 char string `\n' etc.).
3093 * src/output.c (output_rule_data): Use quotearg to output the
3096 2001-12-13 Paul Eggert <eggert@twinsun.com>
3098 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3099 Do not infringe on the global user namespace when using C++.
3100 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3101 All uses of `fprintf' and `stderr' changed.
3103 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3105 2001-12-13 Akim Demaille <akim@epita.fr>
3107 The computation of nullable is broken: it doesn't handle empty
3110 * tests/torture.at (GNU AWK Grammar): New.
3111 * tests/sets.at (Nullable): New.
3112 * src/nullable.c (set_nullable): Instead of blindly looping over
3113 `ritems', loop over the rules, and then over their rhs's.
3115 Work around Autotest bugs.
3117 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
3118 frame, because Autotest understand lines starting with a `+' as
3119 traces from the shell. Then, they are not processed properly.
3120 Admittedly an Autotest bug, but we don't have time to wait for
3121 Autotest to catch up.
3122 * tests/regression.at (Broken Closure): Adjust to the new table
3125 * tests/sets.at: here.
3127 2001-12-13 Akim Demaille <akim@epita.fr>
3129 * src/closure.c (closure): Use nrules instead of playing tricks
3132 2001-12-13 Akim Demaille <akim@epita.fr>
3134 * src/print.c (print_actions): Output the handling of `$' as the
3135 traces do: shifting the token EOF. Before EOF was treated as a
3137 * tests/regression.at: Adjust some tests.
3138 * src/print_graph.c (print_core): Complete the set of items via
3139 closure. The next-to-final and final states are still unsatisfying,
3140 but that's to be addressed elsewhere.
3141 No longer output the rule numbers, but do output the state number.
3142 A single loop for the shifts + gotos is enough, but picked a
3143 distinct color for each.
3144 (print_graph): Initialize and finalize closure.
3146 2001-12-13 Akim Demaille <akim@epita.fr>
3148 * src/reader.c (readgram): Remove dead code, an strip useless
3150 (get_type): Remove, unused.
3152 2001-12-12 Akim Demaille <akim@epita.fr>
3154 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
3155 on that of lib/error.c.
3157 2001-12-12 Akim Demaille <akim@epita.fr>
3159 Some hosts don't like `/' in includes.
3161 * src/system.h: Include libgettext.h without qualifying the path.
3162 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
3165 2001-12-11 Marc Autret <autret_m@epita.fr>
3167 * src/output.c (output_parser): Remove useless muscle.
3169 2001-12-11 Marc Autret <autret_m@epita.fr>
3171 * src/bison.simple: Remove #line just before %%epilogue. It
3172 is now handled in ...
3173 * src/reader.c (read_additionnal_code): Add the output of a
3174 #line for the epilogue.
3176 2001-12-10 Marc Autret <autret_m@epita.fr>
3178 * src/reader.c (copy_definition): Re-use CPP-outed code which
3179 replace precedent remove.
3180 * src/bison.simple: Remove #line before %%prologue because
3181 %%input-line is wrong at this time.
3183 2001-12-10 Marc Autret <autret_m@epita.fr>
3185 * src/reader.c (symbols_output): Clean up.
3186 * src/output.c (output_gram, output): Clean up.
3188 2001-12-10 Akim Demaille <akim@epita.fr>
3190 * src/lalr.c (initialize_lookaheads): New. Extracted from...
3191 * src/LR0.c (set_state_table): here.
3192 * src/lalr.c (lalr): Call it.
3194 2001-12-10 Akim Demaille <akim@epita.fr>
3196 * src/state.h (shifts): Remove the `number' member: shifts are
3197 attached to state, hence no longer need to be labelled with a
3200 2001-12-10 Akim Demaille <akim@epita.fr>
3202 Now that states have a complete set of members, the linked list of
3203 shifts is useless: just fill directly the state's shifts member.
3205 * src/state.h (shifts): Remove the `next' member.
3206 * src/LR0.c (first_state, last_state): Remove.
3208 (augment_automaton): Don't look for the shifts that must be added
3209 a shift on EOF: it is those of the state we looked for! But now,
3210 since shifts are attached, it is no longer needed to looking
3211 merely by its id: its number.
3213 2001-12-10 Akim Demaille <akim@epita.fr>
3215 * src/LR0.c (augment_automaton): Better variable locality.
3216 Remove an impossible branch: if there is a state corresponding to
3217 the start symbol being shifted, then there is shift for the start
3218 symbol from the initial state.
3220 2001-12-10 Akim Demaille <akim@epita.fr>
3222 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
3223 only when appropriate: when insert_start_shifting_state' is not
3225 * tests/regression.at (Rule Line Numbers): Adjust.
3227 2001-12-10 Akim Demaille <akim@epita.fr>
3229 * src/LR0.c (augment_automaton): Now that all states have shifts,
3230 merge the two cases addition shifts to the initial state.
3232 2001-12-10 Akim Demaille <akim@epita.fr>
3234 * src/lalr.c (set_state_table): Move to...
3236 * src/lalr.c (lalr): Don't call it...
3237 * src/LR0.c (generate_states): do it.
3238 * src/LR0.h (first_state): Remove, only the table is used.
3240 2001-12-10 Akim Demaille <akim@epita.fr>
3242 * src/LR0.h (first_shift, first_reduction): Remove.
3243 * src/lalr.c: Don't use first_shift: find shifts through the
3246 2001-12-10 Akim Demaille <akim@epita.fr>
3248 * src/LR0.c: Attach shifts to states as soon as they are
3250 * src/lalr.c (set_state_table): Instead of assigning shifts to
3251 state, just assert that the mapping was properly done.
3253 2001-12-10 Akim Demaille <akim@epita.fr>
3255 * src/LR0.c (insert_start_shift): Rename as...
3256 (insert_start_shifting_state): this.
3257 (insert_eof_shifting_state, insert_accepting_state): New.
3258 (augment_automaton): Adjust.
3259 Better locality of the variables.
3260 When looking if the start_symbol is shifted from the initial
3261 state, using `while (... symbol != start_symbol ...)' sounds
3262 better than `while (... symbol < start_symbol ...)': If fail
3263 to see how the order between symbols could be relevant!
3265 2001-12-10 Akim Demaille <akim@epita.fr>
3267 * src/getargs.h: Don't declare `spec_name_prefix' and
3268 `spec_file_prefix', declared by src/files.h.
3269 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
3270 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
3271 * src/output.c (prepare): Adjust.
3272 * src/reader.c (symbols_output): Likewise.

3275 2001-12-10 Akim Demaille <akim@epita.fr>
3277 * src/muscle_tab.c (muscle_init): NULL is a better default than
3280 2001-12-10 Akim Demaille <akim@epita.fr>
3282 * src/reader.c (reader): Calling symbols_output once is enough.
3284 2001-12-10 Akim Demaille <akim@epita.fr>
3286 Now that states have a complete set of members, the linked list of
3287 reductions is useless: just fill directly the state's reductions
3290 * src/state.h (struct reductions): Remove member `number' and
3292 * src/LR0.c (first_reduction, last_reduction): Remove.
3293 (save_reductions): Don't link the new reductions, store them in
3295 * src/lalr.c (set_state_table): No need to attach reductions to
3296 states, it's already done.
3297 * src/output.c (output_actions): No longer free the shifts, then
3298 the reductions, then the states: free all the states and their
3301 2001-12-10 Akim Demaille <akim@epita.fr>
3303 * src/options.c (OPTN, DRTV, BOTH): New.
3304 (option_table): Use them.
3306 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
3307 the job of system.h.
3308 * src/options.c: Don't include stdio.h and xalloc.h for the same
3311 2001-12-10 Akim Demaille <akim@epita.fr>
3313 * src/output.c (output, prepare): Make sure the values of the
3314 muscles `action' and `prologue' are 0-terminated.
3316 2001-12-10 Akim Demaille <akim@epita.fr>
3318 Clean up GCC warnings.
3320 * src/reader.c (copy_action): `buf' is not used.
3321 (parse_skel_decl): Be static.
3322 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
3323 * src/options.h (create_long_option_table): Have a real prototype.
3324 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
3325 (hash_delete_at): Return const void *.
3326 Adjust casts to preserve the const.
3328 2001-12-10 Akim Demaille <akim@epita.fr>
3330 * configure.in: Require 2.52g.
3331 M4 is not needed, but AUTOM4TE is.
3333 * tests/Makefile.am: Adjust.
3335 2001-12-10 Akim Demaille <akim@epita.fr>
3337 One structure for states is enough, even though theoretically
3338 there are LR(0) states and LALR(1) states.
3340 * src/lalr.h (state_t): Remove.
3341 (state_table): Be state_t **, not state_t *.
3342 * src/state.h (core, CORE_ALLOC): Rename as...
3343 (state_t, STATE_ALLOC): this.
3344 Add the LALR(1) members: shifts, reductions, errs.
3345 * src/LR0.c (state_table): Rename as...
3346 (state_hash): this, to avoid name clashes with the global
3348 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
3349 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
3351 2001-12-10 Akim Demaille <akim@epita.fr>
3353 Bison dumps core on bash.y.
3354 Reported by Pascal Bart.
3356 * src/warshall.c (bitmatrix_print): New.
3358 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
3359 j must be the outer loop.
3360 * tests/regression.at (Broken Closure): New.
3362 2001-12-05 Akim Demaille <akim@epita.fr>
3364 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
3366 Reported by Peter Hámorský.

3371 (resolve_sr_conflict): Adjust.
3372 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
3374 (state_t.reductions, state_t.shifts): this.
3376 2001-12-05 Akim Demaille <akim@epita.fr>
3378 * src/reduce.c (reduce_grammar_tables): No longer disable the
3379 removal of useless rules via CPP but via `if (0)', so that the
3380 compiler still check the code is valid.
3381 For instance, it should have noticed `rline' no longer exists: use
3382 the `line' member of rule_t.
3383 * src/gram.c (dummy, rline): Remove, unused.
3385 2001-12-05 Akim Demaille <akim@epita.fr>
3387 * src/output.c (pack_vector): Use assert, not berror.
3388 * src/main.c (berror): Remove, unused.
3390 2001-12-05 Akim Demaille <akim@epita.fr>
3392 New experimental feature: if --verbose --trace output all the
3393 items of a state, not only its kernel.
3395 * src/print.c (print_core): If `trace_flag', then invoke closure
3396 before outputting the items of the state (print_core is no longer
3397 a correct name them).
3398 (print_results): Invoke new_closure/free_closure if needed.
3400 2001-12-05 Akim Demaille <akim@epita.fr>
3402 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
3403 * src/closure.c, src/closure.h (itemsetsize): Rename as...
3404 (nitemset): for consistency with the rest of the project.
3406 2001-12-05 Akim Demaille <akim@epita.fr>
3408 * src/closure.c (print_closure): Improve.
3409 (closure): Use it for printing input and output.
3411 2001-12-05 Akim Demaille <akim@epita.fr>
3413 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
3414 indexed by nonterminals.
3416 2001-12-05 Akim Demaille <akim@epita.fr>
3418 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
3420 * src/warshall.h: Remove accidental duplication of the content.
3422 2001-12-05 Akim Demaille <akim@epita.fr>

3438 locality, BITISSET, RESETBIT etc.
3440 2001-12-05 Akim Demaille <akim@epita.fr>
3442 Pessimize the code to simplify it: from now on, all the states
3443 have a valid SHIFTS, which NSHIFTS is possibly 0.
3445 * src/LR0.c (shifts_new): Be global and move to..
3446 * src/state.c, src/state.h: here.
3447 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
3448 * src/print_graph: Adjust.
3450 2001-12-05 Akim Demaille <akim@epita.fr>
3452 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
3453 * src/conflicts.c: Use it.
3454 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
3455 incorrectly ``simplified''.
3457 2001-12-05 Akim Demaille <akim@epita.fr>
3459 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
3460 using the good o' techniques: arrays not pointers, variable

3465 * src/state.h (SHIFT_SYMBOL): New.

3470 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
3471 (print_reductions): De-obfuscate using the good o' techniques:
3472 arrays not pointers, variable locality, BITISSET.

3509 Use arrays instead of pointers.
3511 2001-12-05 Akim Demaille <akim@epita.fr>
3513 * src/lalr.c (maxrhs): Move to...
3514 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
3515 * src/lalr.c (build_relations): Adjust.
3517 2001-12-05 Akim Demaille <akim@epita.fr>
3519 * src/lalr.c (transpose): Free the memory allocated to the
3520 argument, as it is replaced by the results by the unique caller.
3521 (build_relations): Merely invoke transpose: it handles the memory
3523 Improve variable locality.
3524 Avoid variables used as mere abbreviations.
3525 (compute_lookaheads): Use arrays instead of pointers.
3527 2001-12-05 Akim Demaille <akim@epita.fr>
3529 * src/lalr.c (initialize_F): Improve variable locality.

3534 * src/derives.c (print_derives): Display the ruleno.
3535 * src/lalr.c (initialize_F, transpose): Better variable locality
3536 to improve readability.
3537 Avoid variables used as mere abbreviations.
3539 2001-12-05 Akim Demaille <akim@epita.fr>
3541 * src/lalr.c (traverse): Use arrays instead of pointers.
3543 2001-12-05 Akim Demaille <akim@epita.fr>
3545 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
3546 the handling of squeue.
3547 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3549 2001-12-05 Akim Demaille <akim@epita.fr>
3551 Because useless nonterminals are now kept alive (instead of being
3552 `destroyed'), we now sometimes examine them, and store information
3553 related to them. Hence we need to know their number, and adjust
3556 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
3558 * src/LR0.c (allocate_itemsets): The memory allocated to
3559 `symbol_count' was used for two different purpose: once to count
3560 the number of occurrences of each symbol, and later reassigned to
3561 `shift_symbol', containing the symbol that can be shifted from a
3563 Deobfuscate, i.e., allocate, use and free `symbol_count' here
3565 (new_itemsets): Allocate `shift_symbol' here.
3566 (allocate_itemsets): symbol_count includes useless nonterminals.
3568 (free_storage): Use `free', not `XFREE', for pointers that cannot
3571 2001-12-05 Akim Demaille <akim@epita.fr>
3573 * src/nullable.c (set_nullable): Deobfuscate the handling of
3575 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3577 2001-12-05 Akim Demaille <akim@epita.fr>
3579 * src/gram.c, src/gram.h (ritem_print): New.
3580 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
3581 (This useless function was defined only to work around VMS linkers
3582 that can't handle compilation units with variables only).
3583 * src/reduce.c (dump_grammar): Use it to trace the construction of
3586 2001-12-04 Paul Eggert <eggert@twinsun.com>
3588 * src/bison.simple (union yyalloc): Change member names
3589 to be the same as the stack names.
3590 (yyparse): yyptr is now union yyalloc *, not char *.
3591 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
3592 and may generate better code on some machines.
3593 (yystpcpy): Use prototype if __STDC__ is defined, not just
3594 if __cplusplus is defined.
3596 2001-11-30 Akim Demaille <akim@epita.fr>
3598 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
3599 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
3600 Gettext doesn't compile cleanly, and dies with -Werror.
3601 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
3602 Include WARNING_CFLAGS here.
3603 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
3604 before being defined.

3608 * lib/quotearg.h (quotearg_n, quotearg_n_style):
3609 First arg is int, not unsigned.
3610 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
3611 (SIZE_MAX, UINT_MAX): New macros.
3612 (quotearg_n_options): Abort if N is negative.
3613 Avoid overflow check on hosts where size_t is 64 bits and int
3614 is 32 bits, as overflow is impossible there.
3615 Fix off-by-one typo that caused unnecessary reallocation.
3617 2001-11-29 Paul Eggert <eggert@twinsun.com>
3619 Name space cleanup in generated parser.
3621 * doc/bison.texinfo (Bison Parser): Discuss system headers
3622 and their effect on the user name space.
3625 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
3626 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
3627 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
3629 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
3630 on user names when possible.
3632 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
3633 Simplify test for whather <alloca.h> exists.
3635 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
3637 (<stdio.h>): Include if YYDEBUG.
3639 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
3640 ! defined (yyoverflow) && ! defined (yymemcpy).
3642 (yymemcpy, yyparse): Rename local variables as needed so that
3643 they all begin with 'yy'.
3645 (yystrlen, yystpcpy): New functions.
3647 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
3650 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
3651 instead of relying on string.h functions. Use YYSTACK_ALLOC
3652 and YYSTACK_FREE instead of malloc and free.
3654 2001-11-30 Akim Demaille <akim@epita.fr>
3656 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
3657 before their first uses.
3658 (YYBISON, YYPURE): Move to the top of the output.
3660 2001-11-30 Akim Demaille <akim@epita.fr>
3662 * tests/reduce.at (Useless Nonterminals): Fix.
3664 2001-11-30 Akim Demaille <akim@epita.fr>
3666 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
3667 if body instead of `;' to pacify GCC's warnings.
3669 2001-11-30 Akim Demaille <akim@epita.fr>
3671 Instead of mapping the LHS of unused rules to -1, keep the LHS
3672 valid, but flag the rules as invalid.
3674 * src/gram.h (rule_t): `useful' is a new member.
3675 * src/print.c (print_grammar): Adjust.
3676 * src/derives.c (set_derives): Likewise.
3677 * src/reader.c (packgram, reduce_output): Likewise.
3678 * src/reduce.c (reduce_grammar_tables): Likewise.
3679 * tests/reduce.at (Underivable Rules, Useless Rules): New.
3681 2001-11-30 Akim Demaille <akim@epita.fr>
3683 * src/reduce.c (reduce_output): Formatting changes.
3684 * src/print.c (print_results, print_grammar): Likewise.
3685 * tests/regression.at (Rule Line Numbers)
3686 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
3688 2001-11-30 Akim Demaille <akim@epita.fr>
3690 * src/reduce.c (nonterminals_reduce): Instead of throwing away
3691 useless nonterminals, move them at the end of the symbol arrays.
3692 (reduce_output): Adjust.
3693 * tests/reduce.at (Useless Nonterminals): Adjust.
3695 2001-11-30 Akim Demaille <akim@epita.fr>
3697 * src/reduce.c: Various comment/formatting changes.
3698 (nonterminals_reduce): New, extracted from...
3699 (reduce_grammar_tables): here.
3700 (reduce_grammar): Call nonterminals_reduce.
3702 2001-11-29 Paul Eggert <eggert@twinsun.com>
3704 * src/bison.simple (YYSTACK_REALLOC): Remove.
3705 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
3706 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
3708 (union yyalloc): New type.
3709 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
3710 an arbitrary restriction on hosts where size_t is wider than int.
3712 (yyparse): Don't dump core if alloca or malloc fails; instead, report
3713 a parser stack overflow. Allocate just one block of memory for all
3714 three stacks, instead of allocating three blocks; this typically is
3715 faster and reduces fragmentation.
3717 Do not limit the number of items in the stack to a value that fits
3718 in 'int', as this is an arbitrary limit on hosts with 64-bit
3719 size_t and 32-bit int.
3721 2001-11-29 Marc Autret <autret_m@epita.fr>
3723 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
3724 of defining YYERROR_VERBOSE.
3725 [AT_DATA]: $4 is now out of C declarations in the prologue.
3727 2001-11-28 Marc Autret <autret_m@epita.fr>
3729 * src/reader.c (parse_dquoted_param): New.

3734 2001-11-28 Marc Autret <autret_m@epita.fr>
3736 * src/output.h: And put its extern declaration here.
3737 * src/output.c (error_verbose): Define here.
3738 (prepare): Echo name modification.
3739 * src/getargs.h: Clean its extern declaration.
3740 * src/getargs.c (error_verbose_flag): Remove.
3741 (getargs): Remove case 'e'.
3742 * src/options.c (option_table): 'error-verbose' is now seen as simple
3746 * src/reader.c (read_declarations): Remove case tok_include.
3747 (parse_include_decl): Remove.

5930 * bison.s1 (yyparse): Assign the default value
5931 unconditionally, to avoid a GCC warning and make the parser a
5934 2000-10-02 Akim Demaille <akim@epita.fr>
5936 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
5939 2000-10-02 Akim Demaille <akim@epita.fr>
5941 * src/derives.c, src/print.c, src/reduce.c: To ease the
5942 translation, move some `\n' out of the translated strings.
5944 2000-10-02 Akim Demaille <akim@epita.fr>
5946 The location tracking mechanism is precious for parse error
5947 messages. Nevertheless, it is enabled only when `@n' is used in
5948 the grammar, which is a different issue (you can use it in error
5949 message, but not in the grammar per se). Therefore, there should
5950 be another means to enable it.
5952 * src/getargs.c (getargs): Support `--locations'.
5954 * src/getargs.h (locationsflag): Export it.
5955 * src/lex.c (percent_table): Support `%locations'.
5956 * src/reader.c (yylsp_needed): Remove this variable, now replaced
5957 with `locationsflag'.
5958 * doc/bison.texinfo: Document `--locations' and `%locations'.
5960 * tests/calc.m4: Test it.
5962 For regularity of the names, replace each
5963 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
5964 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
5965 In addition replace each `flag' with `_flag'.
5967 2000-10-02 Akim Demaille <akim@epita.fr>
5969 Also test parse error messages, including with YYERROR_VERBOSE.
5971 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
5973 Use it to check the computations.
5974 Use it to check `nonassoc' is honored.
5975 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
5976 `--yyerror-verbose'.
5977 (_AT_CHECK_CALC): Adjust to this option.
5978 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
5980 2000-10-02 Akim Demaille <akim@epita.fr>
5982 Test also `--verbose', `--defines' and `--name-prefix'. Testing
5983 the latter demonstrates a flaw in the handling of non debugging
5984 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
5985 was used in order to simplify:
6001 unfortunately this leads to a CPP conflict when
6002 `--name-prefix=foo' is used since it produces `#define yydebug
6005 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6006 (YYDPRINTF): New macro.
6008 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6010 Also test `--verbose', `--defines' and `--name-prefix'.
6012 2000-10-02 Akim Demaille <akim@epita.fr>
6014 Improve the readability of the produced parsers.
6016 * src/bison.s1: Formatting changes.
6017 Improve the comment related to the `$' mark.
6018 (yydefault): Don't fall through to `yyresume': `goto' there.
6019 * src/output.c (output_parser): When the `$' is met, skip the end
6021 New variable, `number_of_dollar_signs', to check there's exactly
6022 one `$' in the parser skeleton.
6024 2000-10-02 Akim Demaille <akim@epita.fr>
6026 * lib/xstrdup.c: New file, from the fileutils.
6027 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6028 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6029 instead of strlen + xmalloc + strcpy.
6030 * src/symtab.c (copys): Remove, use xstrdup instead.
6032 2000-10-02 Akim Demaille <akim@epita.fr>
6034 * src/gram.h (associativity): New enum type which replaces the
6035 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6036 `right_assoc', `left_assoc' and `non_assoc'.
6037 Adjust all dependencies.
6038 * src/reader.c: Formatting changes.
6039 (LTYPESTR): Don't define it, use it as a literal in
6040 `reader_output_yylsp'.
6041 * src/symtab.h (symbol_class): New enum type which replaces the
6042 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
6043 `sunknown', `stoken and `snterm'.
6045 2000-10-02 Akim Demaille <akim@epita.fr>
6047 * src/getargs.c (fixed_outfiles): Rename as...
6048 (yaccflag): for consistency and accuracy.
6049 Adjust dependencies.
6051 2000-10-02 Akim Demaille <akim@epita.fr>
6053 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6054 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
6055 difficult and introduced a lot of core dump. It turns out that
6056 Bison used an implementation of `xmalloc' based on `calloc', and
6057 at various places it does depend upon the initialization to 0. I
6058 have not tried to isolate the pertinent places, and all the former
6059 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
6060 someone should address this issue.
6062 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
6063 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

6077 * src/state.h (nstates, final_state, first_state, first_shift)
6078 (first_reduction): Move their exportation from here...
6079 * src/LR0.h: to here.
6080 Adjust dependencies.
6081 * src/getargs.c (statisticsflag): New variable.
6082 Add support for `--statistics'.

6158 YYDEFACT, that makes it possible for this function to use
6161 2000-10-02 Akim Demaille <akim@epita.fr>
6163 `user_toknums' is output as a `short[]' in `output.c', while it is
6164 defined as a `int[]' in `reader.c'. For consistency with the
6165 other output tables, `user_toknums' is now defined as a table of

6208 Don't define PARAMS.
6209 * src/system.h: Define PARAMS.
6210 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
6211 purpose of config.h. system.h must not try to fix wrong

6376 2000-03-17 Akim Demaille <akim@epita.fr>
6378 On syntax errors, report the token on which we choked.
6380 * src/bison.s1 (yyparse): In the label yyerrlab, when

6426 (copy_guard): Likewise.
6428 2000-03-17 Akim Demaille <akim@epita.fr>
6430 Change the handling of @s so that they behave exactly like $s.
6431 There is now a pseudo variable @$ (readble and writable), location
6432 of the lhs of the rule (by default ranging from the location of
6433 the first symbol of the rhs, to the location of the last symbol,
6434 or, if the rhs is empty, YYLLOC).
6436 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
6438 (yyparse): When providing a default semantic action, provide a
6439 default location action.
6440 (after the $): No longer change `*YYLSP', just stack YYLOC the
6441 same way you stack YYVAL.
6442 * src/reader.c (read_declarations): Use warns.
6443 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
6444 (copy_action, case '@'): Likewise.
6445 Use a standard error message, to save useless work from

6466 2000-03-16 Akim Demaille <akim@epita.fr>
6468 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
6469 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
6470 One `#if YYDEBUG' remains, since it uses variables which are
6471 defined only if `YYDEBUG != 0'.
6473 2000-03-16 Akim Demaille <akim@epita.fr>
6475 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

6493 (VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED.
6494 (AC_OUTPUT): Add m4/Makefile.
6495 Bump to bison 1.28a, 1.29 has never been released.
6496 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are

7134 * src/symtab.h (SALIAS):
7135 New #define for adding aliases to %token.
7136 (struct bucket): Added `alias' field.
7138 * src/reduce.c (reduce_grammar):
7139 Revise error message.
7140 (print_notices): Remove final `.' from error message.
7142 * src/reader.c (reader_output_yylsp):
7144 (readgram): Use `#if 0' around code that accepted %command
7145 inside grammar rules: The documentation doesn't allow it,
7146 and it will fail since the %command processors scan for the next %.
7147 (parse_token_decl): Extended the %token
7148 declaration to allow a multi-character symbol as an alias.
7149 (parse_thong_decl): New function.
7150 (read_declarations): Added %thong declarations.
7151 (read_declarations): Handle NOOP to deal with allowing
7152 % declarations as another means to specify the flags.
7153 (readgram): Allow %prec prior to semantics embedded in a rule.
7154 (skip_to_char, read_declarations, copy_definition)
7155 (parse_token_decl, parse_start_decl, parse_type_decl)
7156 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
7157 (get_type_name, copy_guard, copy_action, readgram)
7158 (get_type, packsymbols): Revised most error messages.
7159 Changed `fatal' to `warnxxx' to avoid aborting for error.
7160 Revised and use multiple warnxxx functions to avoid using VARARGS1.
7161 (read_declarations): Improve the error message for
7162 an invalid character. Do not abort.
7163 (read_declarations, copy_guard, copy_action): Use
7164 printable_version to avoid unprintable characters in printed output.
7165 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
7166 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
7167 Allow the type of a non-terminal can be given
7168 more than once, as long as all specifications give the same type.
7171 (output_headers, output_trailers, output, output_gram)
7172 (output_rule_data): Implement noparserflag variable.
7173 Implement toknumflag variable.
7174 (output): Call reader_output_yylsp to output LTYPESTR.
7176 * src/main.c (main):
7177 If reader sees an error, don't process the grammar.
7178 (fatals): Updated to not use VARARGS1.
7179 (printable_version, int_to_string, warn, warni, warns, warnss)
7180 (warnsss): New error reporting functions. Avoid abort for error.
7183 Added THONG and NOOP for alias processing.
7184 Added SETOPT for the new code that allows setting options with %flags.
7187 Include getopt.h. Add some extern decls.
7188 (safegetc): New function to deal with EOF gracefully.
7189 (literalchar); new function to deal with reading \ escapes.
7190 (lex): Use literalchar.
7191 (lex): Implemented "..." tokens.
7192 (literalchar, lex, parse_percent_token): Made tokenbuffer
7193 always contain the token. This includes growing the token
7194 buffer while reading an integer.
7195 (parse_percent_token): Replaced if-else statement with percent_table.
7196 (parse_percent_token): Added % declarations as another
7197 way to specify the flags -n, -l, and -r. Also added hooks for
7198 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
7199 major changes to files.c.
7200 (lex) Retain in the incoming stream a character following
7202 (skip_white_space, lex): Revised most error messages
7203 and changed fatal to warn to avoid aborting.
7204 (percent_table): Added %thong declarations.
7206 * src/gram.h: Comment changes.
7208 * src/files.c (openfiles, open_extra_files, done):
7210 and actfile file. Handle noparserflag. Both for -n switch.
7212 * src/conflicts.c (resolve_sr_conflict):
7213 Remove use of alloca.
