2147 * data/bison.c++: Replace some direct m4 expansions by constants. Be
2148 more consistent when naming methods and variables. Put preprocessor
2149 directives around tables only needed for debugging.
2151 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
2153 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
2155 (yy::b4_name::parse): Use print_.
2157 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
2159 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
2161 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
2163 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
2165 (yy::b4_name::parse): Build verbose error messages, and use error_.
2167 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
2169 * data/bison.c++: Fix m4 quoting in comments.
2171 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
2173 * data/bison.c++: Adjust the parser code. Fix some muscles that were
2176 2002-02-05 Akim Demaille <akim@epita.fr>
2178 * data/bison.c++: Adjust to the M4 back end.
2179 More is certainly needed.
2181 2002-02-05 Akim Demaille <akim@epita.fr>
2183 Give a try to M4 as a back end.
2185 * lib/readpipe.c: New, from wdiff.
2186 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
2188 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
2189 specific values. Now it is m4 that performs the lookup.
2190 * src/parse-skel.y: Remove.
2191 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
2192 * src/output.c (actions_output, guards_output)
2193 (token_definitions_output): No longer keeps track of the output
2194 line number, hence remove the second argument.
2195 (guards_output): Check against the guard member of a rule, not the
2198 (output_skeleton): Don't look for the skeleton location, let m4 do
2200 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
2202 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2203 (prepare): Given that for the time being changesyntax is not
2204 usable in M4, rename the muscles using `-' to `_'.
2205 Define `defines_flag', `output_parser_name' and `output_header_name'.
2206 * src/output.h (actions_output, guards_output)
2207 (token_definitions_output): Adjust prototypes.
2208 * src/scan-skel.l: Instead of scanning the skeletons, it now
2209 processes the output of m4: `__oline__' and `#output'.
2210 * data/bison.simple: Adjust to be used by M4(sugar).
2211 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
2213 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
2214 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
2215 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
2216 shamelessly stolen from CVS Autoconf.
2218 2002-02-05 Akim Demaille <akim@epita.fr>
2220 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
2221 * configure.in: Check for the declarations of free and malloc.
2222 * src/muscle_tab.c: Adjust.
2224 2002-02-05 Akim Demaille <akim@epita.fr>
2226 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
2227 which have no values.
2229 2002-02-05 Akim Demaille <akim@epita.fr>
2231 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
2234 2002-01-29 Paul Eggert <eggert@twinsun.com>
2236 * src/bison.simple (YYSIZE_T): Do not define merely because
2237 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
2238 On some platforms, <alloca.h> does not declare YYSTD (size_t).
2240 2002-01-27 Akim Demaille <akim@epita.fr>
2242 Fix `%nonassoc and eof'.
2244 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
2245 which were not properly copied! Replace
2246 memcpy (res->errs, src->errs, src->nerrs);
2248 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
2250 * tests/regression.at (%nonassoc and eof): Adjust to newest
2251 Autotest: `.' is not in the PATH.
2253 2002-01-27 Akim Demaille <akim@epita.fr>
2255 * tests/sets.at (AT_EXTRACT_SETS): New.
2259 2002-01-26 Akim Demaille <akim@epita.fr>
2261 * tests/actions.at, tests/calc.at, tests/headers.at,
2262 * tests/torture.at: Adjust to the newest Autotest which no longer
2263 forces `.' in the PATH.
2265 2002-01-25 Akim Demaille <akim@epita.fr>
2267 * tests/regression.at (%nonassoc and eof): New.
2268 Suggested by Robert Anisko.
2270 2002-01-24 Akim Demaille <akim@epita.fr>
2272 Bison dumps core when trying to complain about broken input files.
2273 Reported by Cris van Pelt.
2275 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
2276 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
2278 (Invalid inputs): Strengthen: exercise parse_percent_token.
2280 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
2282 * src/Makefile.am: Add bison.c++.
2283 * src/bison.c++: New skeleton.
2285 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
2289 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
2291 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
2293 2002-01-20 Marc Autret <marc@gnu.org>
2295 * src/files.c (compute_output_file_names): Fix
2297 2002-01-20 Marc Autret <marc@gnu.org>
2299 * tests/output.at: New test.
2300 * src/files.c (compute_base_names): Don't map extensions when
2301 the YACC flag is set, use defaults.
2302 Reported by Evgeny Stambulchik.
2304 2002-01-20 Marc Autret <marc@gnu.org>
2306 * src/system.h: Need to define __attribute__ away for non-GCC
2307 compilers as well (i.e. the vendor C compiler).
2308 Suggested by Albert Chin-A-Young.
2310 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
2312 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
2313 canonical definition.
2314 * src/system.h: Use the canonical definition for PARAMS (avoids
2315 a conflict with the macro from lib/hash.h).
2317 2002-01-11 Akim Demaille <akim@epita.fr>
2319 * configure.in: Use AC_FUNC_STRNLEN.
2320 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
2322 2002-01-09 Akim Demaille <akim@epita.fr>
2324 * src/files.c, src/files.h (output_infix): New.
2325 (tab_extension): Remove.
2326 (compute_base_names): Compute the former, drop the latter.
2327 * src/output.c (prepare): Insert the muscles `output-infix', and
2329 * src/parse-skel.y (string, string.1): New.
2330 (section.header): Use it.
2331 (section.yacc): Remove.
2332 (prefix): Remove too.
2333 * src/scan-skel.l: Adjust.
2334 * src/bison.simple, src/bison.hairy: Adjust.
2336 2002-01-09 Akim Demaille <akim@epita.fr>
2338 * configure.in (WERROR_CFLAGS): Compute it.
2339 * src/Makefile.am (CFLAGS): Pass it.
2340 * tests/atlocal.in (CFLAGS): Idem.
2341 * src/files.c: Fix a few warnings.
2342 (get_extension_index): Remove, unused.
2344 2002-01-08 Akim Demaille <akim@epita.fr>
2346 * src/getargs.c (AS_FILE_NAME): New.
2347 (getargs): Use it to convert DOSish file names.
2348 * src/files.c (base_name): Rename as full_base_name to avoid
2349 clashes with `base_name ()'.
2350 (filename_split): New.
2351 (compute_base_names): N-th rewrite, using filename_split.
2353 2002-01-08 Akim Demaille <akim@epita.fr>
2355 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
2356 New, stolen from the Fileutils 4.1.
2357 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
2358 * configure.in: Check for the presence of memrchr, and of its
2361 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
2363 * lib/hash.h (__P): Added definition for this macro.
2364 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
2365 BUILT_SOURCES, to ensure they are generated first.
2366 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
2367 %error-verbose to allow bootstrapping with bison 1.30x.
2369 2002-01-06 Akim Demaille <akim@epita.fr>
2371 * src/reader.c (parse_braces): Don't fetch the next char, the
2372 convention is to fetch on entry.
2373 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
2374 'switch' without a following semicolon.
2375 * tests/regression.at (braces parsing): New.
2377 2002-01-06 Akim Demaille <akim@epita.fr>
2379 Bison is dead wrong in its RR conflict reports.
2381 * tests/torture.at (GNU Cim Grammar): New.
2382 * src/conflicts.c (count_rr_conflicts): Fix.
2384 2002-01-06 Akim Demaille <akim@epita.fr>
2386 Creating package.m4 from configure.ac causes too many problems.
2388 * tests/Makefile.am (package.m4): Create it by hand,
2389 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
2391 2002-01-06 Akim Demaille <akim@epita.fr>
2393 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
2396 2002-01-04 Paul Eggert <eggert@twinsun.com>
2398 * doc/bison.texinfo (Debugging):
2399 Remove YYSTDERR; it's no longer defined or used.
2400 Also, s/cstdio.h/cstdio/.
2402 2002-01-03 Akim Demaille <akim@epita.fr>
2404 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
2406 2002-01-03 Akim Demaille <akim@epita.fr>
2408 * src/parse-skel.y (process_skeleton): Don't bind the parser's
2409 tracing code to --trace, wait for a better --trace option, with
2412 2002-01-03 Akim Demaille <akim@epita.fr>
2414 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
2415 The ISO C++ standard is extremely clear about it: stderr is
2416 considered a macro, not a regular symbol (see table 94 `Header
2417 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
2418 Therefore std:: does not apply to it. It still does with fprintf.
2419 Also, s/cstdio.h/cstdio/.
2421 2002-01-03 Akim Demaille <akim@epita.fr>
2423 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
2424 for non system headers.
2426 2002-01-02 Akim Demaille <akim@epita.fr>
2428 Equip the skeleton chain with location tracking, runtime trace,
2429 pure parser and scanner.
2431 * src/parse-skel.y: Request a pure parser, locations, and prefix
2433 (%union): Having several members with the same type does not help
2434 type mismatches, simplify.
2435 (YYPRINT, yyprint): New.
2436 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
2439 * src/scan-skel.l: Adjust to these changes.
2440 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
2441 (LOCATION_PRINT, skel_control_t): New.
2443 2001-12-30 Akim Demaille <akim@epita.fr>
2445 * src/parse-skel.y: Get rid of the shift/reduce conflict:
2446 replace `gb' with BLANKS.
2447 * src/scan-skel.l: Adjust.
2449 2001-12-30 Akim Demaille <akim@epita.fr>
2451 * src/system.h: We don't need nor want bcopy.
2452 Throw away MS-DOS crap: we don't need getpid.
2453 * configure.in: We don't need strndup. It was even causing
2454 problems: because Flex includes the headers *before* us,
2455 _GNU_SOURCE is not defined by config.h, and therefore strndup was
2457 * lib/xstrndup.c: New.
2458 * src/scan-skel.l: Use it.
2459 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
2460 * src/parse-skel.y: Use %directives instead of #defines.
2462 2001-12-30 Akim Demaille <akim@epita.fr>
2464 * src/skeleton.h: New.
2465 * src/output.c (output_parser, output_master_parser): Remove, dead
2467 * src/output.h (get_lines_number, actions_output, guards_output)
2468 (token_definitions_output): Prototype them.
2469 * src/parse-skel.y: Add the license notice.
2470 Include output.h and skeleton.h.
2471 (process_skeleton): Returns void, and takes a single parameter.
2472 * src/scan-skel.l: Add the license notice.
2474 Don't use %option yylineno: it seems that then Flex imagines
2475 REJECT has been used, and therefore it won't reallocate its
2476 buffers (which makes no other sense to me than a bug). It results
2477 in warnings for `unused: yy_flex_realloc'.
2479 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
2481 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2482 (MUSCLE_INSERT_PREFIX): ...to there.
2483 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2484 (MUSCLE_INSERT_PREFIX): Move from here...
2486 * src/bison.hairy: Add a section directive. Put braces around muscle
2487 names. This parser skeleton is still broken, but Bison should not
2488 choke on a bad muscle 'syntax'.
2489 * src/bison.simple: Add a section directive. Put braces around muscle
2492 * src/files.h (strsuffix, stringappend): Add declarations.
2493 (tab_extension): Add declaration.
2494 (short_base_name): Add declaration.
2496 * src/files.c (strsuffix, stringappend): No longer static. These
2497 functions are used in the skeleton parser.
2498 (tab_extension): New.
2499 (compute_base_names): Use the computations done in this function
2500 to guess if the generated parsers should have '.tab' in their
2502 (short_base_name): No longer static.
2504 * src/output.c (output_skeleton): New.
2505 (output): Disable call to output_master_parser, and give a try to
2506 a new skeleton handling system.
2507 (guards_output, actions_output): No longer static.
2508 (token_definitions_output, get_lines_number): No longer static.
2510 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
2512 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
2515 * src/parse-skel.y: New file.
2516 * src/scan-skel.l: New file.
2518 2001-12-29 Akim Demaille <akim@epita.fr>
2520 %name-prefix is broken.
2522 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
2523 Adjust all dependencies.
2524 * tests/headers.at (export YYLTYPE): Strengthen this test: use
2527 Renaming yylval but not yylloc is not consistent. Now we do.
2529 * src/bison.simple: Prefix yylloc if used.
2530 * doc/bison.texinfo (Decl Summary): Document that.
2532 2001-12-29 Akim Demaille <akim@epita.fr>
2534 * doc/bison.texinfo: Promote `%long-directive' over
2536 Remove all references to fixed-output-files, yacc is enough.
2538 2001-12-29 Akim Demaille <akim@epita.fr>
2540 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
2541 user prologue. These are defaults.
2542 * tests/actions.at (Mid-rule actions): Make sure the user can
2543 define YYDEBUG and YYERROR_VERBOSE.
2545 2001-12-29 Akim Demaille <akim@epita.fr>
2547 * src/output.c (header_output): Don't forget to export YYLTYPE and
2549 * tests/headers.at (export YYLTYPE): New, make sure it does.
2550 * tests/regression.at (%union and --defines, Invalid CPP headers):
2552 * tests/headers.at: here.
2554 2001-12-29 Akim Demaille <akim@epita.fr>
2556 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
2558 2001-12-29 Akim Demaille <akim@epita.fr>
2560 * tests/actions.at (Mid-rule actions): Output on a single line
2563 2001-12-29 Akim Demaille <akim@epita.fr>
2565 * doc/bison.texinfo: Formatting changes.
2567 2001-12-29 Akim Demaille <akim@epita.fr>
2569 Don't store the token defs in a muscle, just be ready to output it
2570 on command. Now possible via `symbols'. Fixes a memory leak.
2572 * src/output.c (token_definitions_output): New.
2573 (output_parser, header_output): Use it.
2574 * src/reader.c (symbols_save): Remove.
2576 2001-12-29 Akim Demaille <akim@epita.fr>
2578 * src/bison.simple: Do not provide a default for YYSTYPE and
2579 YYLTYPE before the user's prologue. Otherwise it's hardly... a
2582 2001-12-29 Akim Demaille <akim@epita.fr>
2584 Mid-rule actions are simply... ignored!
2586 * src/reader.c (readgram): Be sure to attach mid-rule actions to
2587 the empty-rule associated to the dummy symbol, not to the host
2589 * tests/actions.at (Mid-rule actions): New.
2591 2001-12-29 Akim Demaille <akim@epita.fr>
2595 * src/reader.c (reader): Free grammar.
2597 2001-12-29 Akim Demaille <akim@epita.fr>
2601 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
2602 since it allocates it for each state, although only one is needed.
2603 (allocate_storage): Do it here.
2605 2001-12-29 Akim Demaille <akim@epita.fr>
2607 * src/options.h, src/options.c (create_long_option_table): Rename
2609 (long_option_table_new): this, with a clearer prototype.
2610 (percent_table): Remove, unused,
2611 * src/getargs.c (getargs): Adjust.
2613 2001-12-29 Akim Demaille <akim@epita.fr>
2615 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
2616 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
2619 2001-12-29 Akim Demaille <akim@epita.fr>
2621 * src/lalr.c (build_relations): Rename `states' as `states1'.
2622 Sorry, I don't understand exactly what it is, no better name...
2624 2001-12-29 Akim Demaille <akim@epita.fr>
2626 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
2627 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
2628 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
2631 2001-12-29 Akim Demaille <akim@epita.fr>
2633 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
2636 2001-12-29 Akim Demaille <akim@epita.fr>
2638 * src/reader.c, src/reader.h (user_toknums): Remove.
2639 Adjust all users to use symbols[i]->user_token_number.
2641 2001-12-29 Akim Demaille <akim@epita.fr>
2643 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
2644 Adjust all users to use symbols[i]->prec or ->assoc.
2646 2001-12-29 Akim Demaille <akim@epita.fr>
2648 * src/reader.c, src/reader.h (tags): Remove.
2649 Adjust all users to use symbols[i]->tag.
2651 2001-12-29 Akim Demaille <akim@epita.fr>
2653 * src/gram.h, src/gram.c (symbols): New, similar to state_table
2655 * src/reader.c (packsymbols): Fill this table.
2657 * src/conflicts.c (resolve_sr_conflict): Adjust.
2658 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
2660 Use symbols[i]->tag instead of tags[i].
2662 2001-12-29 Akim Demaille <akim@epita.fr>
2664 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
2665 In addition, put a comment in there, to replace...
2666 * tests/regression.at (%union and C comments): Remove.
2668 2001-12-29 Akim Demaille <akim@epita.fr>
2670 * tests/regression.at (Web2c Actions): Blindly move the actual
2671 output as expected output. The contents *seem* right to me, but I
2672 can't pretend reading perfectly parser tables... Nonetheless, all
2673 the other tests pass correctly, the table look OK, even though the
2674 presence of `$axiom' is to be noted: AFAICS it is useless (but
2677 2001-12-29 Akim Demaille <akim@epita.fr>
2679 * src/reader.c (readgram): Don't add the rule 0 if there were no
2680 rules read. In other words, add it _after_ having performed
2681 grammar sanity checks.
2682 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
2684 2001-12-29 Akim Demaille <akim@epita.fr>
2686 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
2687 visible, and some states have now a different number.
2689 2001-12-29 Akim Demaille <akim@epita.fr>
2691 * src/reader.c (readgram): Bind the initial rule's lineno to that
2693 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
2694 (Solved SR Conflicts): Adjust rule 0's line number.
2696 2001-12-29 Akim Demaille <akim@epita.fr>
2698 Fix the `GAWK Grammar' failure.
2700 * src/LR0.c (final_state): Initialize to -1 so that we do compute
2701 the reductions of the first state which was mistakenly confused
2702 with the final state because precisely final_state was initialized
2704 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
2705 now noticed by Bison.
2706 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
2707 have a reduction on $default.
2709 2001-12-29 Akim Demaille <akim@epita.fr>
2711 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
2713 * src/closure.c (print_closure): Likewise.
2714 * src/derives.c (print_derives): Likewise.
2715 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
2718 2001-12-29 Akim Demaille <akim@epita.fr>
2720 * src/lalr.c (lookaheads_print): New.
2721 (lalr): Call it when --trace-flag.
2722 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
2725 2001-12-29 Akim Demaille <akim@epita.fr>
2727 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
2728 when walking through ritem, even via rule->rhs.
2729 * src/reduce.c (dump_grammar, useful_production, reduce_output)
2730 (useful_production, useless_nonterminals): Likewise.
2731 (reduce_grammar_tables): Likewise, plus update nritems.
2732 * src/nullable.c (set_nullable): Likewise.
2733 * src/lalr.c (build_relations): Likewise.
2734 * tests/sets.at (Nullable): Adjust.
2735 Fortunately, now, the $axiom is no longer nullable.
2737 2001-12-29 Akim Demaille <akim@epita.fr>
2739 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
2741 * src/gram.c (ritem_longest_rhs): Likewise.
2742 * src/reduce.c (nonterminals_reduce): Likewise.
2743 * src/print_graph.c (print_graph): Likewise.
2744 * src/output.c (output_rule_data): Likewise.
2745 * src/nullable.c (set_nullable): Likewise.
2747 2001-12-29 Akim Demaille <akim@epita.fr>
2749 * src/output.c: Comment changes.
2751 2001-12-27 Paul Eggert <eggert@twinsun.com>
2753 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
2754 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
2755 Sparc, as they were causing more porting problems than the
2756 (minor) performance improvement was worth.
2758 Also, catch up with 1.31's YYSTD.
2760 2001-12-27 Akim Demaille <akim@epita.fr>
2762 * src/output.c (output_gram): Rely on nritems, not the
2763 0-sentinel. See below.
2764 Use -1 as separator, not 0.
2765 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
2766 Rely on -1 as separator in yyrhs, instead of 0.
2767 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
2768 twice `Now at end of input', therefore there are two lines less to
2771 2001-12-27 Akim Demaille <akim@epita.fr>
2773 * tests/regression.at (Unresolved SR Conflicts):
2774 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
2777 2001-12-27 Akim Demaille <akim@epita.fr>
2779 * src/LR0.c (new_state): Recognize the final state by the fact it
2780 is reached by eoftoken.
2781 (insert_start_shifting_state, insert_eof_shifting_state)
2782 (insert_accepting_state, augment_automaton): Remove, since now
2783 these states are automatically computed from the initial state.
2784 (generate_states): Adjust.
2785 * src/print.c: When reporting a rule number to the user, substract
2786 1, so that the axiom rule is rule 0, and the first user rule is 1.
2787 * src/reduce.c: Likewise.
2788 * src/print_graph.c (print_core): For the time being, just as for
2789 the report, depend upon --trace-flags to dump the full set of
2791 * src/reader.c (readgram): Once the grammar read, insert the rule
2792 0: `$axiom: START-SYMBOL $'.
2793 * tests/set.at: Adjust: rule 0 is now displayed, and since the
2794 number of the states has changed (the final state is no longer
2795 necessarily the last), catch up.
2797 2001-12-27 Akim Demaille <akim@epita.fr>
2799 Try to make the use of the eoftoken valid. Given that its value
2800 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
2801 is used instead of > 0 where appropriate, (ii), depend upon nritems
2802 instead of the 0-sentinel.
2804 * src/gram.h, src/gram.c (nritems): New.
2805 Expected to be duplication of nitems, but for the time being...
2806 * src/reader.c (packgram): Assert nritems and nitems are equal.
2807 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
2808 * src/closure.c (print_closure, print_fderives): Likewise.
2809 * src/gram.c (ritem_print): Likewise.
2810 * src/print.c (print_core, print_grammar): Likewise.
2811 * src/print_graph.c: Likewise.
2813 2001-12-27 Akim Demaille <akim@epita.fr>
2815 * src/main.c (main): If there are complains after grammar
2816 reductions, then output the report anyway if requested, then die.
2817 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
2818 * src/reader.c (eoftoken): New.
2819 (parse_token_decl): If the token being defined has value `0', it
2821 (packsymbols): No longer hack `tags' to insert `$' by hand.
2822 Be sure to preserve the value of the eoftoken.
2823 (reader): Make sure eoftoken is defined.
2824 Initialize nsyms to 0: now eoftoken is created just like the others.
2825 * src/print.c (print_grammar): Don't special case the eof token.
2826 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
2827 lie anyway, albeit pleasant.
2828 * tests/calc.at: Exercise error messages with eoftoken.
2829 Change the grammar so that empty input is invalid.
2830 Adjust expectations.
2831 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
2833 2001-12-27 Akim Demaille <akim@epita.fr>
2835 * configure.in: Check the protos of strchr ans strspn.
2836 Replace strchr if needed.
2837 * src/system.h: Provide the protos of strchr, strspn and memchr if
2839 * lib/strchr.c: New.
2840 * src/reader.c (symbols_save): Use strchr.
2842 2001-12-27 Akim Demaille <akim@epita.fr>
2844 * src/print.c, src/print_graph.c (escape): New.
2845 Use it to quote the TAGS outputs.
2846 * src/print_graph.c (print_state): Now errors are in red, and
2847 reductions in green.
2848 Prefer high to wide: output the state number on a line of its own.
2850 2001-12-27 Akim Demaille <akim@epita.fr>
2852 * src/state.h, src/state.c (reductions_new): New.

2871 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
2873 2001-12-27 Akim Demaille <akim@epita.fr>
2875 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
2876 * src/print.c: here.
2877 (lookaheadset, shiftset): New, used as additional storage by
2879 (print_results): Adjust.
2880 (print_shifts, print_gotos, print_errs): New, extracted from...
2881 (print_actions): here.
2882 * src/print_graph.c (print_actions): Remove dead code.
2884 2001-12-27 Akim Demaille <akim@epita.fr>

2906 * src/output.c (output): Adjust.
2907 * src/reader.c (parse_braces): New, factoring...
2908 (copy_action, copy_guard): these two which are renamed as...
2909 (parse_action, parse_guard): these.
2910 As a voluntary consequence, using braces around guards is now
2913 2001-12-27 Akim Demaille <akim@epita.fr>
2915 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
2916 * src/reader.c (symbol_list): `guard' and `guard_line' are new
2918 (symbol_list_new): Adjust.
2919 (copy_action): action_line is the first line, not the last.
2920 (copy_guard): Just as for actions, store the `action' only, not
2921 the switch/case/break flesh.
2922 Don't parse the user action that might follow the guard, let...
2923 (readgram): do it, i.e., now, there can be an action after a
2925 In other words the guard is just explicitly optional.
2927 * src/output.c (guards_output): New.
2928 (output_parser): Call it when needed.
2929 (output): Also free the guard and attrs obstacks.
2930 * src/files.c, src/files.h (obstack_save): Remove.
2931 (output_files): Remove.
2932 As a result, if one needs the former `.act' file, using an
2933 appropriate skeleton which requires actions and guards is now
2935 * src/main.c (main): Adjust.
2936 * tests/semantic.at: New.
2937 * tests/regression.at: Use `input.y' as input file name.
2938 Avoid 8+3 problems by requiring input.c when the test needs the

2943 * src/reader.c (symbol_list_new): Be sure to initialize all the
2946 2001-12-27 Akim Demaille <akim@epita.fr>
2948 All the hacks using a final pseudo state are now useless.
2950 * src/LR0.c (set_state_table): state_table holds exactly nstates.
2951 * src/lalr.c (nLA): New.
2952 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
2953 instead of lookaheadsp from the pseudo state (nstate + 1).
2955 2001-12-27 Akim Demaille <akim@epita.fr>
2957 * src/output.c (action_row, token_actions): Use a state_t instead
2958 of a integer, and nlookaheads instead of the following state's

2963 * src/conflicts.c (log_resolution, flush_shift)
2964 (resolve_sr_conflict, set_conflicts, solve_conflicts)
2965 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
2966 (conflicts_print, print_reductions): Use a state_t instead of an
2967 integer when referring to a state.
2968 As much as possible, depend upon nlookaheads, instead of the
2969 `lookaheadsp' member of the following state (since lookaheads of
2970 successive states are successive, the difference between state n + 1
2971 and n served as the number of lookaheads for state n).
2972 * src/lalr.c (add_lookback_edge): Likewise.
2973 * src/print.c (print_core, print_actions, print_state)
2974 (print_results): Likewise.

2988 * src/output.c (prepare): Drop the muscle `ntbase' which
2990 * src/bison.simple: Formatting/comment changes.
2991 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
2992 is an undocumented synonym.
2994 2001-12-22 Akim Demaille <akim@epita.fr>
2996 * src/output.c (output_table_data): Change the prototype to use
2997 `int' for array ranges: some invocations do pass an int, not a
2999 Reported by Wayne Green.
3001 2001-12-22 Akim Demaille <akim@epita.fr>
3003 Some actions of web2c.y are improperly triggered.
3004 Reported by Mike Castle.
3006 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

3008 (Web2c Report): this.
3009 (Web2c Actions): New.
3011 2001-12-22 Akim Demaille <akim@epita.fr>

3019 2001-12-18 Akim Demaille <akim@epita.fr>
3021 Some host fail on `assert (!"foo")', which expands to
3022 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3023 Reported by Nelson Beebee.
3025 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3026 `#define it_succeeded 0' and `assert (it_succeeded)'.
3028 2001-12-17 Marc Autret <autret_m@epita.fr>
3030 * src/bison.simple: Don't hard code the skeleton line and filename.
3031 * src/output.c (output_parser): Rename 'line' as 'output_line'.
3032 New line counter 'skeleton_line' (skeleton-line muscle).
3034 2001-12-17 Paul Eggert <eggert@twinsun.com>
3036 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3037 YYDEBUG must be defined to a nonzero value.
3039 * src/bison.simple (yytname): Do not assume that the user defines
3040 YYDEBUG to a properly parenthesized expression.
3042 2001-12-17 Akim Demaille <akim@epita.fr>
3044 * src/state.h (state_t): Rename lookaheads as lookaheadsp.

3058 2001-12-17 Akim Demaille <akim@epita.fr>
3060 * src/conflicts.c (print_reductions): Formatting changes.
3062 2001-12-17 Akim Demaille <akim@epita.fr>
3064 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
3065 (flush_reduce): New.
3066 (resolve_sr_conflict): Adjust.
3068 2001-12-17 Akim Demaille <akim@epita.fr>
3070 * src/output.c (output_obstack): Be static and rename as...
3071 (format_obstack): this, to avoid any confusion with files.c's
3073 * src/reader.h (muscle_obstack): Move to...
3074 * src/output.h: here, since it's defined in output.c.
3076 2001-12-17 Akim Demaille <akim@epita.fr>
3078 * src/output.c (action_row, save_column, default_goto)

3094 2001-12-16 Marc Autret <autret_m@epita.fr>
3096 * src/output.c (actions_output): Fix. When we use %no-lines,
3097 there is one less line per action.
3099 2001-12-16 Marc Autret <autret_m@epita.fr>
3101 * src/bison.simple: Remove a useless #line directive.
3102 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
3103 * src/output.c (get_lines_number): New.
3104 (output_parser): Adjust, now takes care about the lines of a

3121 Make `make distcheck' work.
3123 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3124 system.h which uses libgettext.h.
3126 2001-12-15 Akim Demaille <akim@epita.fr>
3128 * src/nullable.c (set_nullable): Useless rules must be skipped,
3129 otherwise, since we range over their symbols, we might look at a
3130 nonterminal which no longer ``exists'', i.e., it is not counted in
3131 `nvars', hence we overflow our arrays.
3133 2001-12-15 Akim Demaille <akim@epita.fr>
3135 The header can also be produced directly, without any obstack!
3138 * src/files.c, src/files.h (defines_obstack): Remove.
3139 (compute_header_macro): Global.
3140 (defines_obstack_save): Remove.
3141 * src/reader.c (parse_union_decl): No longer output to
3142 defines_obstack: its content can be found in the `stype' muscle

3145 (symbols_output): this.
3147 (symbols_save): this.
3149 * src/output.c (header_output): New.
3152 2001-12-15 Akim Demaille <akim@epita.fr>
3154 * src/reader.c (parse_union_decl): Instead of handling two obstack
3155 simultaneously, use one to define the `stype' muscle, and use the
3156 value of the latter to fill defines_obstack.
3157 (copy_comment): Remove.
3158 (copy_comment2): Work for a single obstack.
3160 (copy_comment): this.
3162 2001-12-15 Akim Demaille <akim@epita.fr>
3164 * src/lex.c, src/lex.h (xgetc): No longer static.
3165 * src/reader.c (parse_union_decl): Revamp.
3167 2001-12-15 Akim Demaille <akim@epita.fr>
3169 Still making progress in separating Bison into (i) input, (ii)
3170 process, (iii) output: now we can directly output the parser file
3171 without using table_obstack at all.
3173 * src/files.c, src/files.h (table_obstack): Bye bye.
3174 (parser_file_name): New.
3175 * src/files.c (compute_output_file_names): Compute it.
3176 * src/output.c (actions_output, output_parser)

3179 2001-12-15 Akim Demaille <akim@epita.fr>
3181 Attach actions to rules, instead of pre-outputting them to
3184 * src/gram.h (rule_t): action and action_line are new members.
3185 * src/reader.c (symbol_list): Likewise.
3186 (copy_action): Save the actions within the rule.
3187 (packgram): Save them in rule_table.
3188 * src/output.c (actions_output): New.
3189 (output_parser): Use it on `%%actions'.
3190 (output_rule_data): Don't free rule_table.
3192 (prepare): Don't save the `action' muscle.
3193 * src/bison.simple: s/%%action/%%actions/.
3195 2001-12-15 Akim Demaille <akim@epita.fr>
3197 * src/reader.c (copy_action): When --yacc, don't append a `;'
3198 to the user action: let it fail if lacking.
3199 Suggested by Arnold Robbins and Tom Tromey.
3201 2001-12-14 Akim Demaille <akim@epita.fr>
3203 * src/lex.c (literalchar): Simply return the char you decoded, non
3204 longer mess around with obstacks and int pointers.
3207 2001-12-14 Akim Demaille <akim@epita.fr>
3209 * src/lex.c (literalchar): Don't escape the special characters,
3210 just decode them, and keep them as char (before, eol was output as
3211 the 2 char string `\n' etc.).
3212 * src/output.c (output_rule_data): Use quotearg to output the
3215 2001-12-13 Paul Eggert <eggert@twinsun.com>
3217 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3218 Do not infringe on the global user namespace when using C++.
3219 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3220 All uses of `fprintf' and `stderr' changed.
3222 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3224 2001-12-13 Akim Demaille <akim@epita.fr>
3226 The computation of nullable is broken: it doesn't handle empty
3229 * tests/torture.at (GNU AWK Grammar): New.
3230 * tests/sets.at (Nullable): New.
3231 * src/nullable.c (set_nullable): Instead of blindly looping over
3232 `ritems', loop over the rules, and then over their rhs's.
3234 Work around Autotest bugs.
3236 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
3237 frame, because Autotest understand lines starting with a `+' as
3238 traces from the shell. Then, they are not processed properly.
3239 Admittedly an Autotest bug, but we don't have time to wait for
3240 Autotest to catch up.
3241 * tests/regression.at (Broken Closure): Adjust to the new table
3244 * tests/sets.at: here.
3246 2001-12-13 Akim Demaille <akim@epita.fr>
3248 * src/closure.c (closure): Use nrules instead of playing tricks
3251 2001-12-13 Akim Demaille <akim@epita.fr>
3253 * src/print.c (print_actions): Output the handling of `$' as the
3254 traces do: shifting the token EOF. Before EOF was treated as a
3256 * tests/regression.at: Adjust some tests.
3257 * src/print_graph.c (print_core): Complete the set of items via
3258 closure. The next-to-final and final states are still unsatisfying,
3259 but that's to be addressed elsewhere.
3260 No longer output the rule numbers, but do output the state number.
3261 A single loop for the shifts + gotos is enough, but picked a
3262 distinct color for each.
3263 (print_graph): Initialize and finalize closure.
3265 2001-12-13 Akim Demaille <akim@epita.fr>
3267 * src/reader.c (readgram): Remove dead code, an strip useless
3269 (get_type): Remove, unused.
3271 2001-12-12 Akim Demaille <akim@epita.fr>
3273 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
3274 on that of lib/error.c.
3276 2001-12-12 Akim Demaille <akim@epita.fr>
3278 Some hosts don't like `/' in includes.
3280 * src/system.h: Include libgettext.h without qualifying the path.
3281 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
3284 2001-12-11 Marc Autret <autret_m@epita.fr>
3286 * src/output.c (output_parser): Remove useless muscle.
3288 2001-12-11 Marc Autret <autret_m@epita.fr>
3290 * src/bison.simple: Remove #line just before %%epilogue. It
3291 is now handled in ...
3292 * src/reader.c (read_additionnal_code): Add the output of a
3293 #line for the epilogue.
3295 2001-12-10 Marc Autret <autret_m@epita.fr>
3297 * src/reader.c (copy_definition): Re-use CPP-outed code which
3298 replace precedent remove.
3299 * src/bison.simple: Remove #line before %%prologue because
3300 %%input-line is wrong at this time.
3302 2001-12-10 Marc Autret <autret_m@epita.fr>
3304 * src/reader.c (symbols_output): Clean up.
3305 * src/output.c (output_gram, output): Clean up.
3307 2001-12-10 Akim Demaille <akim@epita.fr>
3309 * src/lalr.c (initialize_lookaheads): New. Extracted from...
3310 * src/LR0.c (set_state_table): here.
3311 * src/lalr.c (lalr): Call it.
3313 2001-12-10 Akim Demaille <akim@epita.fr>
3315 * src/state.h (shifts): Remove the `number' member: shifts are
3316 attached to state, hence no longer need to be labelled with a
3319 2001-12-10 Akim Demaille <akim@epita.fr>
3321 Now that states have a complete set of members, the linked list of
3322 shifts is useless: just fill directly the state's shifts member.
3324 * src/state.h (shifts): Remove the `next' member.
3325 * src/LR0.c (first_state, last_state): Remove.
3327 (augment_automaton): Don't look for the shifts that must be added
3328 a shift on EOF: it is those of the state we looked for! But now,
3329 since shifts are attached, it is no longer needed to looking
3330 merely by its id: its number.
3332 2001-12-10 Akim Demaille <akim@epita.fr>
3334 * src/LR0.c (augment_automaton): Better variable locality.
3335 Remove an impossible branch: if there is a state corresponding to
3336 the start symbol being shifted, then there is shift for the start
3337 symbol from the initial state.
3339 2001-12-10 Akim Demaille <akim@epita.fr>
3341 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
3342 only when appropriate: when insert_start_shifting_state' is not
3344 * tests/regression.at (Rule Line Numbers): Adjust.
3346 2001-12-10 Akim Demaille <akim@epita.fr>
3348 * src/LR0.c (augment_automaton): Now that all states have shifts,
3349 merge the two cases addition shifts to the initial state.
3351 2001-12-10 Akim Demaille <akim@epita.fr>
3353 * src/lalr.c (set_state_table): Move to...
3355 * src/lalr.c (lalr): Don't call it...
3356 * src/LR0.c (generate_states): do it.
3357 * src/LR0.h (first_state): Remove, only the table is used.
3359 2001-12-10 Akim Demaille <akim@epita.fr>
3361 * src/LR0.h (first_shift, first_reduction): Remove.
3362 * src/lalr.c: Don't use first_shift: find shifts through the
3365 2001-12-10 Akim Demaille <akim@epita.fr>
3367 * src/LR0.c: Attach shifts to states as soon as they are
3369 * src/lalr.c (set_state_table): Instead of assigning shifts to
3370 state, just assert that the mapping was properly done.
3372 2001-12-10 Akim Demaille <akim@epita.fr>
3374 * src/LR0.c (insert_start_shift): Rename as...
3375 (insert_start_shifting_state): this.
3376 (insert_eof_shifting_state, insert_accepting_state): New.
3377 (augment_automaton): Adjust.
3378 Better locality of the variables.
3379 When looking if the start_symbol is shifted from the initial
3380 state, using `while (... symbol != start_symbol ...)' sounds
3381 better than `while (... symbol < start_symbol ...)': If fail
3382 to see how the order between symbols could be relevant!
3384 2001-12-10 Akim Demaille <akim@epita.fr>
3386 * src/getargs.h: Don't declare `spec_name_prefix' and
3387 `spec_file_prefix', declared by src/files.h.
3388 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
3389 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
3390 * src/output.c (prepare): Adjust.
3391 * src/reader.c (symbols_output): Likewise.
3392 * src/vmsgetargs.c: Vaguely adjust, but who cares?
3394 2001-12-10 Akim Demaille <akim@epita.fr>
3396 * src/muscle_tab.c (muscle_init): NULL is a better default than
3399 2001-12-10 Akim Demaille <akim@epita.fr>
3401 * src/reader.c (reader): Calling symbols_output once is enough.
3403 2001-12-10 Akim Demaille <akim@epita.fr>
3405 Now that states have a complete set of members, the linked list of
3406 reductions is useless: just fill directly the state's reductions
3409 * src/state.h (struct reductions): Remove member `number' and
3411 * src/LR0.c (first_reduction, last_reduction): Remove.
3412 (save_reductions): Don't link the new reductions, store them in
3414 * src/lalr.c (set_state_table): No need to attach reductions to
3415 states, it's already done.
3416 * src/output.c (output_actions): No longer free the shifts, then
3417 the reductions, then the states: free all the states and their
3420 2001-12-10 Akim Demaille <akim@epita.fr>
3422 * src/options.c (OPTN, DRTV, BOTH): New.
3423 (option_table): Use them.
3425 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
3426 the job of system.h.
3427 * src/options.c: Don't include stdio.h and xalloc.h for the same
3430 2001-12-10 Akim Demaille <akim@epita.fr>
3432 * src/output.c (output, prepare): Make sure the values of the
3433 muscles `action' and `prologue' are 0-terminated.
3435 2001-12-10 Akim Demaille <akim@epita.fr>
3437 Clean up GCC warnings.
3439 * src/reader.c (copy_action): `buf' is not used.
3440 (parse_skel_decl): Be static.
3441 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
3442 * src/options.h (create_long_option_table): Have a real prototype.
3443 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
3444 (hash_delete_at): Return const void *.
3445 Adjust casts to preserve the const.
3447 2001-12-10 Akim Demaille <akim@epita.fr>
3449 * configure.in: Require 2.52g.
3450 M4 is not needed, but AUTOM4TE is.
3452 * tests/Makefile.am: Adjust.
3454 2001-12-10 Akim Demaille <akim@epita.fr>
3456 One structure for states is enough, even though theoretically
3457 there are LR(0) states and LALR(1) states.
3459 * src/lalr.h (state_t): Remove.
3460 (state_table): Be state_t **, not state_t *.
3461 * src/state.h (core, CORE_ALLOC): Rename as...
3462 (state_t, STATE_ALLOC): this.
3463 Add the LALR(1) members: shifts, reductions, errs.
3464 * src/LR0.c (state_table): Rename as...
3465 (state_hash): this, to avoid name clashes with the global
3467 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
3468 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
3470 2001-12-10 Akim Demaille <akim@epita.fr>
3472 Bison dumps core on bash.y.
3473 Reported by Pascal Bart.
3475 * src/warshall.c (bitmatrix_print): New.
3477 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
3478 j must be the outer loop.
3479 * tests/regression.at (Broken Closure): New.
3481 2001-12-05 Akim Demaille <akim@epita.fr>
3483 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
3485 Reported by Peter Hámorský.
3487 2001-12-05 Akim Demaille <akim@epita.fr>
3489 * src/conflicts.c (err_table): Remove.
3490 (resolve_sr_conflict): Adjust.
3491 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
3493 (state_t.reductions, state_t.shifts): this.
3495 2001-12-05 Akim Demaille <akim@epita.fr>
3497 * src/reduce.c (reduce_grammar_tables): No longer disable the
3498 removal of useless rules via CPP but via `if (0)', so that the
3499 compiler still check the code is valid.
3500 For instance, it should have noticed `rline' no longer exists: use
3501 the `line' member of rule_t.
3502 * src/gram.c (dummy, rline): Remove, unused.
3504 2001-12-05 Akim Demaille <akim@epita.fr>
3506 * src/output.c (pack_vector): Use assert, not berror.
3507 * src/main.c (berror): Remove, unused.
3509 2001-12-05 Akim Demaille <akim@epita.fr>
3511 New experimental feature: if --verbose --trace output all the
3512 items of a state, not only its kernel.
3514 * src/print.c (print_core): If `trace_flag', then invoke closure
3515 before outputting the items of the state (print_core is no longer
3516 a correct name them).
3517 (print_results): Invoke new_closure/free_closure if needed.
3519 2001-12-05 Akim Demaille <akim@epita.fr>
3521 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
3522 * src/closure.c, src/closure.h (itemsetsize): Rename as...
3523 (nitemset): for consistency with the rest of the project.
3525 2001-12-05 Akim Demaille <akim@epita.fr>
3527 * src/closure.c (print_closure): Improve.
3528 (closure): Use it for printing input and output.
3530 2001-12-05 Akim Demaille <akim@epita.fr>
3532 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
3533 indexed by nonterminals.
3535 2001-12-05 Akim Demaille <akim@epita.fr>
3537 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
3539 * src/warshall.h: Remove accidental duplication of the content.
3541 2001-12-05 Akim Demaille <akim@epita.fr>

3555 * src/output.c (action_row): De-obfuscate
3556 using the good o' techniques: arrays not pointers, variable
3557 locality, BITISSET, RESETBIT etc.
3559 2001-12-05 Akim Demaille <akim@epita.fr>
3561 Pessimize the code to simplify it: from now on, all the states
3562 have a valid SHIFTS, which NSHIFTS is possibly 0.
3564 * src/LR0.c (shifts_new): Be global and move to..
3565 * src/state.c, src/state.h: here.
3566 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
3567 * src/print_graph: Adjust.
3569 2001-12-05 Akim Demaille <akim@epita.fr>
3571 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
3572 * src/conflicts.c: Use it.
3573 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
3574 incorrectly ``simplified''.
3576 2001-12-05 Akim Demaille <akim@epita.fr>
3578 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
3579 using the good o' techniques: arrays not pointers, variable
3580 locality, BITISSET, RESETBIT etc.
3582 2001-12-05 Akim Demaille <akim@epita.fr>
3584 * src/state.h (SHIFT_SYMBOL): New.
3585 * src/conflicts.c: Use it to deobfuscate.
3587 2001-12-05 Akim Demaille <akim@epita.fr>
3589 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
3590 (print_reductions): De-obfuscate using the good o' techniques:
3591 arrays not pointers, variable locality, BITISSET.
3593 2001-12-05 Akim Demaille <akim@epita.fr>
3595 * src/conflicts.c (print_reductions): Arrays, not pointers.
3598 2001-12-05 Akim Demaille <akim@epita.fr>

3610 2001-12-05 Akim Demaille <akim@epita.fr>
3612 * src/conflicts.c (print_reductions): Improve variable locality.
3614 2001-12-05 Akim Demaille <akim@epita.fr>

3621 * src/LR0.c (augment_automaton): Formatting changes.
3622 Better variable locality.

3626 * src/lalr.c (matrix_print): New.
3627 (transpose): Use it.
3628 Use arrays instead of pointers.
3630 2001-12-05 Akim Demaille <akim@epita.fr>
3632 * src/lalr.c (maxrhs): Move to...

3634 * src/lalr.c (build_relations): Adjust.
3636 2001-12-05 Akim Demaille <akim@epita.fr>
3638 * src/lalr.c (transpose): Free the memory allocated to the
3639 argument, as it is replaced by the results by the unique caller.
3640 (build_relations): Merely invoke transpose: it handles the memory
3642 Improve variable locality.
3643 Avoid variables used as mere abbreviations.
3644 (compute_lookaheads): Use arrays instead of pointers.
3646 2001-12-05 Akim Demaille <akim@epita.fr>
3648 * src/lalr.c (initialize_F): Improve variable locality.

3662 2001-12-05 Akim Demaille <akim@epita.fr>
3664 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
3665 the handling of squeue.
3666 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3668 2001-12-05 Akim Demaille <akim@epita.fr>
3670 Because useless nonterminals are now kept alive (instead of being
3671 `destroyed'), we now sometimes examine them, and store information
3672 related to them. Hence we need to know their number, and adjust
3675 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
3677 * src/LR0.c (allocate_itemsets): The memory allocated to
3678 `symbol_count' was used for two different purpose: once to count
3679 the number of occurrences of each symbol, and later reassigned to
3680 `shift_symbol', containing the symbol that can be shifted from a
3682 Deobfuscate, i.e., allocate, use and free `symbol_count' here
3684 (new_itemsets): Allocate `shift_symbol' here.
3685 (allocate_itemsets): symbol_count includes useless nonterminals.
3687 (free_storage): Use `free', not `XFREE', for pointers that cannot
3690 2001-12-05 Akim Demaille <akim@epita.fr>
3692 * src/nullable.c (set_nullable): Deobfuscate the handling of
3694 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3696 2001-12-05 Akim Demaille <akim@epita.fr>
3698 * src/gram.c, src/gram.h (ritem_print): New.
3699 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
3700 (This useless function was defined only to work around VMS linkers
3701 that can't handle compilation units with variables only).
3702 * src/reduce.c (dump_grammar): Use it to trace the construction of
3705 2001-12-04 Paul Eggert <eggert@twinsun.com>
3707 * src/bison.simple (union yyalloc): Change member names
3708 to be the same as the stack names.
3709 (yyparse): yyptr is now union yyalloc *, not char *.
3710 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
3711 and may generate better code on some machines.
3712 (yystpcpy): Use prototype if __STDC__ is defined, not just
3713 if __cplusplus is defined.
3715 2001-11-30 Akim Demaille <akim@epita.fr>
3717 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
3718 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
3719 Gettext doesn't compile cleanly, and dies with -Werror.
3720 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
3721 Include WARNING_CFLAGS here.
3722 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
3723 before being defined.
3725 2001-11-27 Paul Eggert <eggert@twinsun.com>
3727 * lib/quotearg.h (quotearg_n, quotearg_n_style):
3728 First arg is int, not unsigned.
3729 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
3730 (SIZE_MAX, UINT_MAX): New macros.
3731 (quotearg_n_options): Abort if N is negative.
3732 Avoid overflow check on hosts where size_t is 64 bits and int
3733 is 32 bits, as overflow is impossible there.
3734 Fix off-by-one typo that caused unnecessary reallocation.
3736 2001-11-29 Paul Eggert <eggert@twinsun.com>
3738 Name space cleanup in generated parser.
3740 * doc/bison.texinfo (Bison Parser): Discuss system headers
3741 and their effect on the user name space.
3744 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,

3786 if body instead of `;' to pacify GCC's warnings.
3788 2001-11-30 Akim Demaille <akim@epita.fr>
3790 Instead of mapping the LHS of unused rules to -1, keep the LHS
3791 valid, but flag the rules as invalid.
3793 * src/gram.h (rule_t): `useful' is a new member.
3794 * src/print.c (print_grammar): Adjust.
3795 * src/derives.c (set_derives): Likewise.

3828 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
3829 an arbitrary restriction on hosts where size_t is wider than int.
3831 (yyparse): Don't dump core if alloca or malloc fails; instead, report
3832 a parser stack overflow. Allocate just one block of memory for all
3833 three stacks, instead of allocating three blocks; this typically is
3834 faster and reduces fragmentation.
3836 Do not limit the number of items in the stack to a value that fits
3837 in 'int', as this is an arbitrary limit on hosts with 64-bit
3838 size_t and 32-bit int.

5922 (done): Rename as...
5923 (output_files): this.
5925 * src/main.c (main): Don't use `atexit' to register `done', since
5926 it no longer has to remove tmp files, just call `output_files'
5927 when there are no errors.
5929 2000-11-02 Akim Demaille <akim@epita.fr>
5931 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
5932 `unlink': it's no longer used.
5933 * src/files.h: Formatting changes.
5935 2000-11-02 Akim Demaille <akim@epita.fr>

5962 Change each use of `faction' into a use of `action_obstack'.

5998 * src/reader.c (copy_comment2): Expect the input stream to be on
5999 the `/' which is suspected to open a comment, instead of being
6000 called after `//' or `/*' was read.
6001 (copy_comment, copy_definition, parse_union_decl, copy_action)
6002 (copy_guard): Adjust.
6004 2000-10-16 Akim Demaille <akim@epita.fr>

6030 2000-10-04 Akim Demaille <akim@epita.fr>
6032 When a literal string is used to define two different tokens,
6033 `bison -v' segfaults.
6034 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
6036 * tests/regression.m4: New file.
6037 Include the core of the sample provided by Piotr Gackiewicz.

6061 translation, move some `\n' out of the translated strings.
6063 2000-10-02 Akim Demaille <akim@epita.fr>
6065 The location tracking mechanism is precious for parse error
6066 messages. Nevertheless, it is enabled only when `@n' is used in
6067 the grammar, which is a different issue (you can use it in error
6068 message, but not in the grammar per se). Therefore, there should
6069 be another means to enable it.
6071 * src/getargs.c (getargs): Support `--locations'.
6073 * src/getargs.h (locationsflag): Export it.
6074 * src/lex.c (percent_table): Support `%locations'.

6084 In addition replace each `flag' with `_flag'.
6086 2000-10-02 Akim Demaille <akim@epita.fr>
6088 Also test parse error messages, including with YYERROR_VERBOSE.
6090 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6092 Use it to check the computations.
6093 Use it to check `nonassoc' is honored.
6094 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
6095 `--yyerror-verbose'.

6097 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
6099 2000-10-02 Akim Demaille <akim@epita.fr>
6101 Test also `--verbose', `--defines' and `--name-prefix'. Testing
6102 the latter demonstrates a flaw in the handling of non debugging
6103 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6104 was used in order to simplify:
6120 unfortunately this leads to a CPP conflict when
6121 `--name-prefix=foo' is used since it produces `#define yydebug
6124 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6125 (YYDPRINTF): New macro.
6127 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6129 Also test `--verbose', `--defines' and `--name-prefix'.

6133 Improve the readability of the produced parsers.
6135 * src/bison.s1: Formatting changes.
6136 Improve the comment related to the `$' mark.
6137 (yydefault): Don't fall through to `yyresume': `goto' there.
6138 * src/output.c (output_parser): When the `$' is met, skip the end
6140 New variable, `number_of_dollar_signs', to check there's exactly
6141 one `$' in the parser skeleton.
6143 2000-10-02 Akim Demaille <akim@epita.fr>
6145 * lib/xstrdup.c: New file, from the fileutils.
6146 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6147 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6148 instead of strlen + xmalloc + strcpy.
6149 * src/symtab.c (copys): Remove, use xstrdup instead.
6151 2000-10-02 Akim Demaille <akim@epita.fr>
6153 * src/gram.h (associativity): New enum type which replaces the
6154 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with

6156 Adjust all dependencies.
6157 * src/reader.c: Formatting changes.

6159 `reader_output_yylsp'.
6160 * src/symtab.h (symbol_class): New enum type which replaces the
6161 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

6167 (yaccflag): for consistency and accuracy.
6168 Adjust dependencies.
6170 2000-10-02 Akim Demaille <akim@epita.fr>
6172 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6173 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
6174 difficult and introduced a lot of core dump. It turns out that
6175 Bison used an implementation of `xmalloc' based on `calloc', and
6176 at various places it does depend upon the initialization to 0. I
6177 have not tried to isolate the pertinent places, and all the former
6178 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
6179 someone should address this issue.
6181 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

6282 `user_toknums' is output as a `short[]' in `output.c', while it is
6283 defined as a `int[]' in `reader.c'. For consistency with the
6284 other output tables, `user_toknums' is now defined as a table of

6327 Don't define PARAMS.
6328 * src/system.h: Define PARAMS.

6588 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
6589 One `#if YYDEBUG' remains, since it uses variables which are

7261 * src/reader.c (reader_output_yylsp):
7263 (readgram): Use `#if 0' around code that accepted %command
7264 inside grammar rules: The documentation doesn't allow it,

7267 declaration to allow a multi-character symbol as an alias.
7268 (parse_thong_decl): New function.
7269 (read_declarations): Added %thong declarations.

7279 Revised and use multiple warnxxx functions to avoid using VARARGS1.
7280 (read_declarations): Improve the error message for
7281 an invalid character. Do not abort.
7282 (read_declarations, copy_guard, copy_action): Use
7283 printable_version to avoid unprintable characters in printed output.
7284 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
7285 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

7291 (output_rule_data): Implement noparserflag variable.
7292 Implement toknumflag variable.
7293 (output): Call reader_output_yylsp to output LTYPESTR.

7309 (lex): Use literalchar.
7310 (lex): Implemented "..." tokens.
7311 (literalchar, lex, parse_percent_token): Made tokenbuffer
7312 always contain the token. This includes growing the token
7313 buffer while reading an integer.
7314 (parse_percent_token): Replaced if-else statement with percent_table.
7315 (parse_percent_token): Added % declarations as another
7316 way to specify the flags -n, -l, and -r. Also added hooks for
7317 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
7318 major changes to files.c.
7319 (lex) Retain in the incoming stream a character following
7321 (skip_white_space, lex): Revised most error messages
7322 and changed fatal to warn to avoid aborting.
7323 (percent_table): Added %thong declarations.
7325 * src/gram.h: Comment changes.
