1395 (Table of Symbols): Describe $$, $n, @$, and @n.
1396 Suggested by Tim Josling.
1397
1398 2002-04-19 Akim Demaille <akim@epita.fr>
1399
1400 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
1401
1402 2002-04-10 Akim Demaille <akim@epita.fr>
1403
1404 * src/system.h: Rely on HAVE_LIMITS_H.
1405 Suggested by Paul Eggert.
1406
1407 2002-04-09 Akim Demaille <akim@epita.fr>
1408
1409 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
1410 full stderr, and strip it according to the bison options, instead
1411 of composing the error message from different bits.
1412 This makes it easier to check for several error messages.
1413 Adjust all the invocations.
1414 Add an invocation exercising the error token.
1415 Add an invocation demonstrating a stupid error message.
1416 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
1417 Adjust the tests.
1418 Error message are for stderr, not stdout.
1419
1420 2002-04-09 Akim Demaille <akim@epita.fr>
1421
1422 * src/gram.h, src/gram.c (error_token_number): Remove, use
1423 errtoken->number.
1424 * src/reader.c (reader): Don't specify the user token number (2)
1425 for $undefined, as it uselessly prevents using it.
1426 * src/gram.h (token_number_t): Move to...
1427 * src/symtab.h: here.
1428 (state_t.number): Is a token_number_t.
1429 * src/print.c, src/reader.c: Use undeftoken->number instead of
1430 hard coded 2.
1431 (Even though this 2 is not the same as above: the number of the
1432 undeftoken remains being 2, it is its user token number which
1433 might not be 2).
1434 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
1435 `user_token_number_max'.
1436 Output `undef_token_number'.
1437 * data/bison.simple, data/bison.c++: Use them.
1438 Be sure to map invalid yylex return values to
1439 `undef_token_number'. This saves us from gratuitous SEGV.
1440
1441 * tests/conflicts.at (Solved SR Conflicts)
1442 (Unresolved SR Conflicts): Adjust.
1443 * tests/regression.at (Web2c Actions): Adjust.
1444
1445 2002-04-08 Akim Demaille <akim@epita.fr>
1446
1447 * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
1448 Adding #line.
1449 Remove the duplicate `typedefs'.
1450 (RhsNumberType): Fix the declaration and various other typos.
1451 Use __ofile__.
1452 * data/bison.simple: Use __ofile__.
1453 * src/scan-skel.l: Handle __ofile__.

1456
1457 * src/gram.h (item_number_t): New, the type of item numbers in
1458 RITEM. Note that it must be able to code symbol numbers as
1459 positive number, and the negation of rule numbers as negative
1460 numbers.
1461 Adjust all dependencies (pretty many).
1462 * src/reduce.c (rule): Remove this `short *' pointer: use
1463 item_number_t.
1464 * src/system.h (MINSHORT, MAXSHORT): Remove.
1465 Include `limits.h'.
1466 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
1467 (shortcpy): Remove.

1469 * src/output.c (MAXTABLE): here.
1470 (prepare_rules): Use output_int_table to output rhs.

1472 * tests/torture.at (Big triangle): Move the limit from 254 to
1473 500.
1474 * tests/regression.at (Web2c Actions): Ajust.
1475
1476 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
1477 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
1478 passes, but produces negative #line number, once fixed, GCC is
1479 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
1480 C), it passes.
1481 * src/state.h (state_h): Code input lines on ints, not shorts.
1482
1483 2002-04-08 Akim Demaille <akim@epita.fr>
1484
1485 * src/reduce.c (reduce_grammar): First reduce the nonterminals,
1486 and then the grammar.

1498 New.
1499 Use them to define yy_token_number_type/TokenNumberType.
1500 Use this type for yytranslate.
1501 * tests/torture.at (Big triangle): Push the limit from 124 to
1502 253.
1503 * tests/regression.at (Web2c Actions): Adjust.

1505 2002-04-07 Akim Demaille <akim@epita.fr>
1506
1507 * tests/torture.at (Big triangle): New.
1508 (GNU AWK Grammar, GNU Cim Grammar): Move to...
1509 * tests/existing.at: here.
1510
1511 2002-04-07 Akim Demaille <akim@epita.fr>
1512
1513 * src/gram.h, src/gram.c (nitems): Remove, it is an alias of
1514 nritems.
1515 Adjust dependencies.

1579
1580 2002-04-07 Akim Demaille <akim@epita.fr>

1601
1602 2002-04-07 Akim Demaille <akim@epita.fr>

1608
1609 2002-04-07 Akim Demaille <akim@epita.fr>
1610
1611 Be sure never to walk through RITEMS, but use only data related to

1613
1614 * src/output.c (output_token_translations): Rename as...
1615 (prepare_tokens): this.

1629
1630 * src/LR0.c (new_state): Display `nstates' as the name of the
1631 newly created state.
1632 Adjust to initialize first_state and last_state if needed.
1633 Be sure to distinguish the initial from the final state.
1634 (new_states): Create the itemset of the initial state, and use
1635 new_state.
1636 * src/closure.c (closure): Now that the initial state has its
1637 items properly set, there is no need for a special case when
1638 creating `ruleset'.
1639
1640 As a result, now the rule 0, reducing to $axiom, is visible in the
1641 outputs. Adjust the test suite.

1679 2002-04-07 Akim Demaille <akim@epita.fr>
1680
1681 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
1682 lacking `+ 1' to nrules, Bison reported as useless a token if it
1683 was used solely to set the precedence of the last rule...
1684
1685 2002-04-07 Akim Demaille <akim@epita.fr>
1686
1687 * data/bison.c++, data/bison.simple: Don't output the current file
1688 name in #line, to avoid useless diffs between two identical
1689 outputs under different names.

1692
1693 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

1710 RHS, instead of being an index in RITEMS.

1978
1979 2002-02-14 Paul Eggert <eggert@twinsun.com>
1980
1981 Remove the support for C++ namespace cleanliness; it was
1982 causing more problems than it was curing, since it didn't work

2033
2034 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

2077 action member.
2078 Adjust callers.
2079 (output_skeleton): Don't look for the skeleton location, let m4 do
2080 that.
2081 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
2082 file will be used.
2083 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2084 (prepare): Given that for the time being changesyntax is not
2085 usable in M4, rename the muscles using `-' to `_'.

2087 * src/output.h (actions_output, guards_output)
2088 (token_definitions_output): Adjust prototypes.
2089 * src/scan-skel.l: Instead of scanning the skeletons, it now

2092 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
2093 to date.

2118 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

2121 2002-01-27 Akim Demaille <akim@epita.fr>
2122
2123 Fix `%nonassoc and eof'.
2124
2125 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
2126 which were not properly copied! Replace
2127 memcpy (res->errs, src->errs, src->nerrs);
2128 with
2129 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
2130 !!!
2131 * tests/regression.at (%nonassoc and eof): Adjust to newest
2132 Autotest: `.' is not in the PATH.

2290 tracing code to --trace, wait for a better --trace option, with
2291 args.
2292
2293 2002-01-03 Akim Demaille <akim@epita.fr>
2294
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/.
2301
2302 2002-01-03 Akim Demaille <akim@epita.fr>
2303
2304 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
2305 for non system headers.
2306
2307 2002-01-02 Akim Demaille <akim@epita.fr>
2308
2309 Equip the skeleton chain with location tracking, runtime trace,
2310 pure parser and scanner.
2311
2312 * src/parse-skel.y: Request a pure parser, locations, and prefix
2313 renaming.
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...
2318 (skel_error): this.
2319 Handle locations.
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.
2323
2324 2001-12-30 Akim Demaille <akim@epita.fr>
2325
2326 * src/parse-skel.y: Get rid of the shift/reduce conflict:
2327 replace `gb' with BLANKS.
2328 * src/scan-skel.l: Adjust.
2329
2330 2001-12-30 Akim Demaille <akim@epita.fr>
2331
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
2337 not visible.
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.
2342
2343 2001-12-30 Akim Demaille <akim@epita.fr>
2344
2345 * src/skeleton.h: New.
2346 * src/output.c (output_parser, output_master_parser): Remove, dead
2347 code.
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.
2354 Include skeleton.h.
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'.
2359
2360 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
2361
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...
2366
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
2371 names.
2372
2373 * src/files.h (strsuffix, stringappend): Add declarations.
2374 (tab_extension): Add declaration.
2375 (short_base_name): Add declaration.
2376
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
2382 names.
2383 (short_base_name): No longer static.
2384
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.
2390
2391 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
2392
2393 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
2394 parse-skel.y.
2395
2396 * src/parse-skel.y: New file.
2397 * src/scan-skel.l: New file.
2398
2399 2001-12-29 Akim Demaille <akim@epita.fr>
2400
2401 %name-prefix is broken.
2402
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
2406 %name-prefix.
2407
2408 Renaming yylval but not yylloc is not consistent. Now we do.
2409
2410 * src/bison.simple: Prefix yylloc if used.
2411 * doc/bison.texinfo (Decl Summary): Document that.
2412
2413 2001-12-29 Akim Demaille <akim@epita.fr>
2414
2415 * doc/bison.texinfo: Promote `%long-directive' over
2416 `%long_directive'.
2417 Remove all references to fixed-output-files, yacc is enough.
2418
2419 2001-12-29 Akim Demaille <akim@epita.fr>
2420
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.
2425
2426 2001-12-29 Akim Demaille <akim@epita.fr>
2427
2428 * src/output.c (header_output): Don't forget to export YYLTYPE and
2429 yylloc.
2430 * tests/headers.at (export YYLTYPE): New, make sure it does.
2431 * tests/regression.at (%union and --defines, Invalid CPP headers):
2432 Move to...
2433 * tests/headers.at: here.
2434
2435 2001-12-29 Akim Demaille <akim@epita.fr>
2436
2437 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
2438
2439 2001-12-29 Akim Demaille <akim@epita.fr>
2440
2441 * tests/actions.at (Mid-rule actions): Output on a single line
2442 instead of several.
2443
2444 2001-12-29 Akim Demaille <akim@epita.fr>
2445
2446 * doc/bison.texinfo: Formatting changes.
2447
2448 2001-12-29 Akim Demaille <akim@epita.fr>
2449
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.
2452
2453 * src/output.c (token_definitions_output): New.
2454 (output_parser, header_output): Use it.
2455 * src/reader.c (symbols_save): Remove.
2456
2457 2001-12-29 Akim Demaille <akim@epita.fr>
2458
2459 * src/bison.simple: Do not provide a default for YYSTYPE and
2460 YYLTYPE before the user's prologue. Otherwise it's hardly... a
2461 default.
2462
2463 2001-12-29 Akim Demaille <akim@epita.fr>
2464
2465 Mid-rule actions are simply... ignored!
2466
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
2469 rule.
2470 * tests/actions.at (Mid-rule actions): New.
2471
2472 2001-12-29 Akim Demaille <akim@epita.fr>
2473
2474 Memory leak.
2475
2476 * src/reader.c (reader): Free grammar.
2477
2478 2001-12-29 Akim Demaille <akim@epita.fr>
2479
2480 Memory leak.
2481
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.
2485
2486 2001-12-29 Akim Demaille <akim@epita.fr>
2487
2488 * src/options.h, src/options.c (create_long_option_table): Rename
2489 as...
2490 (long_option_table_new): this, with a clearer prototype.
2491 (percent_table): Remove, unused,
2492 * src/getargs.c (getargs): Adjust.
2493
2494 2001-12-29 Akim Demaille <akim@epita.fr>
2495
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
2498 as states.
2499
2500 2001-12-29 Akim Demaille <akim@epita.fr>
2501
2502 * src/lalr.c (build_relations): Rename `states' as `states1'.
2503 Sorry, I don't understand exactly what it is, no better name...
2504
2505 2001-12-29 Akim Demaille <akim@epita.fr>
2506
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
2510 as rules.
2511
2512 2001-12-29 Akim Demaille <akim@epita.fr>
2513
2514 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
2515 ago.
2516
2517 2001-12-29 Akim Demaille <akim@epita.fr>
2518
2519 * src/reader.c, src/reader.h (user_toknums): Remove.
2520 Adjust all users to use symbols[i]->user_token_number.
2521
2522 2001-12-29 Akim Demaille <akim@epita.fr>
2523
2524 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
2525 Adjust all users to use symbols[i]->prec or ->assoc.
2526
2527 2001-12-29 Akim Demaille <akim@epita.fr>
2528
2529 * src/reader.c, src/reader.h (tags): Remove.
2530 Adjust all users to use symbols[i]->tag.
2531
2532 2001-12-29 Akim Demaille <akim@epita.fr>
2533
2534 * src/gram.h, src/gram.c (symbols): New, similar to state_table
2535 and rule_table.
2536 * src/reader.c (packsymbols): Fill this table.
2537 Drop sprec.
2538 * src/conflicts.c (resolve_sr_conflict): Adjust.
2539 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
2540 single table.
2541 Use symbols[i]->tag instead of tags[i].
2542
2543 2001-12-29 Akim Demaille <akim@epita.fr>
2544
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.
2548
2549 2001-12-29 Akim Demaille <akim@epita.fr>
2550
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
2556 harmless).
2557
2558 2001-12-29 Akim Demaille <akim@epita.fr>
2559
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.
2564
2565 2001-12-29 Akim Demaille <akim@epita.fr>
2566
2567 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
2568 visible, and some states have now a different number.
2569
2570 2001-12-29 Akim Demaille <akim@epita.fr>
2571
2572 * src/reader.c (readgram): Bind the initial rule's lineno to that
2573 of the first rule.
2574 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
2575 (Solved SR Conflicts): Adjust rule 0's line number.
2576
2577 2001-12-29 Akim Demaille <akim@epita.fr>
2578
2579 Fix the `GAWK Grammar' failure.
2580
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
2584 to 0.
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.
2589
2590 2001-12-29 Akim Demaille <akim@epita.fr>
2591
2592 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
2593 rule line numbers.
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
2597 now.
2598
2599 2001-12-29 Akim Demaille <akim@epita.fr>
2600
2601 * src/lalr.c (lookaheads_print): New.
2602 (lalr): Call it when --trace-flag.
2603 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
2604 are dumped.
2605
2606 2001-12-29 Akim Demaille <akim@epita.fr>
2607
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.
2617
2618 2001-12-29 Akim Demaille <akim@epita.fr>
2619
2620 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
2621 the 0-sentinel.
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.
2627
2628 2001-12-29 Akim Demaille <akim@epita.fr>
2629
2630 * src/output.c: Comment changes.
2631
2632 2001-12-27 Paul Eggert <eggert@twinsun.com>
2633
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.
2638
2639 Also, catch up with 1.31's YYSTD.
2640
2641 2001-12-27 Akim Demaille <akim@epita.fr>
2642
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
2650 expect.
2651
2652 2001-12-27 Akim Demaille <akim@epita.fr>
2653
2654 * tests/regression.at (Unresolved SR Conflicts):
2655 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
2656 below.
2657
2658 2001-12-27 Akim Demaille <akim@epita.fr>
2659
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
2671 items.
2672 * src/reader.c (readgram): Once the grammar read, insert the rule
2673 0: `$axiom: START-SYMBOL $'.
2674 * tests/set.at: Adjust: rule 0 is now displayed, and since the
2675 number of the states has changed (the final state is no longer
2676 necessarily the last), catch up.
2677
2678 2001-12-27 Akim Demaille <akim@epita.fr>
2679
2680 Try to make the use of the eoftoken valid. Given that its value
2681 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
2682 is used instead of > 0 where appropriate, (ii), depend upon nritems
2683 instead of the 0-sentinel.
2684
2685 * src/gram.h, src/gram.c (nritems): New.
2686 Expected to be duplication of nitems, but for the time being...
2687 * src/reader.c (packgram): Assert nritems and nitems are equal.
2688 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
2689 * src/closure.c (print_closure, print_fderives): Likewise.
2690 * src/gram.c (ritem_print): Likewise.
2691 * src/print.c (print_core, print_grammar): Likewise.
2692 * src/print_graph.c: Likewise.
2693
2694 2001-12-27 Akim Demaille <akim@epita.fr>
2695
2696 * src/main.c (main): If there are complains after grammar
2697 reductions, then output the report anyway if requested, then die.
2698 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
2699 * src/reader.c (eoftoken): New.
2700 (parse_token_decl): If the token being defined has value `0', it
2701 is the eoftoken.
2702 (packsymbols): No longer hack `tags' to insert `$' 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.
2713
2714 2001-12-27 Akim Demaille <akim@epita.fr>
2715
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
2719 missing.
2720 * lib/strchr.c: New.
2721 * src/reader.c (symbols_save): Use strchr.
2722
2723 2001-12-27 Akim Demaille <akim@epita.fr>
2724
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.
2730
2731 2001-12-27 Akim Demaille <akim@epita.fr>
2732
2733 * src/state.h, src/state.c (reductions_new): New.
2734 * src/LR0.c (set_state_table): Let all the states have a
2735 `reductions', even if reduced to 0.
2736 (save_reductions): Adjust.
2737 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
2738 * src/print.c (print_reductions, print_actions): Adjust.
2739 * src/output.c (action_row): Adjust.
2740
2741 2001-12-27 Akim Demaille <akim@epita.fr>
2742
2743 * src/state.h, src/state.c (errs_new, errs_dup): New.
2744 * src/LR0.c (set_state_table): Let all the states have an errs,
2745 even if reduced to 0.
2746 * src/print.c (print_errs, print_reductions): Adjust.
2747 * src/output.c (output_actions, action_row): Adjust.
2748 * src/conflicts.c (resolve_sr_conflict): Adjust.
2749
2750 2001-12-27 Akim Demaille <akim@epita.fr>
2751
2752 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
2753
2754 2001-12-27 Akim Demaille <akim@epita.fr>
2755
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
2759 print_reductions.
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.
2764
2765 2001-12-27 Akim Demaille <akim@epita.fr>
2766
2767 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
2768 `$n' and `@n'.
2769
2770 2001-12-27 Akim Demaille <akim@epita.fr>
2771
2772 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
2773 (build_relations): Adjust.
2774
2775 2001-12-27 Akim Demaille <akim@epita.fr>
2776
2777 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
2778 duplication.
2779
2780 2001-12-27 Akim Demaille <akim@epita.fr>
2781
2782 * src/reader.c (packgram): Catch nitems overflows.
2783
2784 2001-12-27 Akim Demaille <akim@epita.fr>
2785
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
2792 mandatory.
2793
2794 2001-12-27 Akim Demaille <akim@epita.fr>
2795
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
2798 members.
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
2805 guard.
2806 In other words the guard is just explicitly optional.
2807 (packgram): Adjust.
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
2815 required.
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
2820 parser.
2821
2822 2001-12-27 Akim Demaille <akim@epita.fr>
2823
2824 * src/reader.c (symbol_list_new): Be sure to initialize all the
2825 fields.
2826
2827 2001-12-27 Akim Demaille <akim@epita.fr>
2828
2829 All the hacks using a final pseudo state are now useless.
2830
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).
2835
2836 2001-12-27 Akim Demaille <akim@epita.fr>
2837
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
2840 lookaheadsp.
2841
2842 2001-12-27 Akim Demaille <akim@epita.fr>
2843
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.
2856 * src/print_graph.c (print_core, print_actions, print_state)
2857 (print_graph): Likewise.
2858 * src/conflicts.h: Adjust.
2859
2860 2001-12-27 Akim Demaille <akim@epita.fr>
2861
2862 * src/bison.hairy: Formatting/comment changes.
2863 ANSIfy.
2864 Remove `register' indications.
2865 Add plenty of `static'.
2866
2867 2001-12-27 Akim Demaille <akim@epita.fr>
2868
2869 * src/output.c (prepare): Drop the muscle `ntbase' which
2870 duplicates ntokens.
2871 * src/bison.simple: Formatting/comment changes.
2872 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
2873 is an undocumented synonym.
2874
2875 2001-12-22 Akim Demaille <akim@epita.fr>
2876
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
2879 short.
2880 Reported by Wayne Green.
2881
2882 2001-12-22 Akim Demaille <akim@epita.fr>
2883
2884 Some actions of web2c.y are improperly triggered.
2885 Reported by Mike Castle.
2886
2887 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
2888 * tests/regression.at (Web2c): Rename as...
2889 (Web2c Report): this.
2890 (Web2c Actions): New.
2891
2892 2001-12-22 Akim Demaille <akim@epita.fr>
2893
2894 Reductions in web2c.y are improperly reported.
2895 Reported by Mike Castle.
2896
2897 * src/conflicts.c (print_reductions): Fix.
2898 * tests/regression.at (Web2c): New.
2899
2900 2001-12-18 Akim Demaille <akim@epita.fr>
2901
2902 Some host fail on `assert (!"foo")', which expands to
2903 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
2904 Reported by Nelson Beebee.
2905
2906 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
2907 `#define it_succeeded 0' and `assert (it_succeeded)'.
2908
2909 2001-12-17 Marc Autret <autret_m@epita.fr>
2910
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).
2914
2915 2001-12-17 Paul Eggert <eggert@twinsun.com>
2916
2917 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
2918 YYDEBUG must be defined to a nonzero value.
2919
2920 * src/bison.simple (yytname): Do not assume that the user defines
2921 YYDEBUG to a properly parenthesized expression.
2922
2923 2001-12-17 Akim Demaille <akim@epita.fr>
2924
2925 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
2926 nlookaheads is a new member.
2927 Adjust all users.
2928 * src/lalr.h (nlookaheads): Remove this orphan declaration.
2929 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
2930 state.
2931
2932 2001-12-17 Akim Demaille <akim@epita.fr>
2933
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,
2936 let...
2937 * src/reader.c (reader): Do it.
2938
2939 2001-12-17 Akim Demaille <akim@epita.fr>
2940
2941 * src/conflicts.c (print_reductions): Formatting changes.
2942
2943 2001-12-17 Akim Demaille <akim@epita.fr>
2944
2945 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
2946 (flush_reduce): New.
2947 (resolve_sr_conflict): Adjust.
2948
2949 2001-12-17 Akim Demaille <akim@epita.fr>
2950
2951 * src/output.c (output_obstack): Be static and rename as...
2952 (format_obstack): this, to avoid any confusion with files.c's
2953 output_obstack.
2954 * src/reader.h (muscle_obstack): Move to...
2955 * src/output.h: here, since it's defined in output.c.
2956
2957 2001-12-17 Akim Demaille <akim@epita.fr>
2958
2959 * src/output.c (action_row, save_column, default_goto)
2960 (sort_actions, matching_state, pack_vector): Better variable
2961 locality.
2962
2963 2001-12-17 Akim Demaille <akim@epita.fr>
2964
2965 * src/output.c: Various formatting changes.
2966
2967 2001-12-17 Akim Demaille <akim@epita.fr>
2968
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.
2974
2975 2001-12-16 Marc Autret <autret_m@epita.fr>
2976
2977 * src/output.c (actions_output): Fix. When we use %no-lines,
2978 there is one less line per action.
2979
2980 2001-12-16 Marc Autret <autret_m@epita.fr>
2981
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
2986 output muscles.
2987 Fix line numbering.
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.
2991
2992 2001-12-15 Marc Autret <autret_m@epita.fr>
2993
2994 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
2995
2996 2001-12-15 Marc Autret <autret_m@epita.fr>
2997
2998 * src/output.c (output_gram): Keep track of the hairy one.
2999
3000 2001-12-15 Akim Demaille <akim@epita.fr>
3001
3002 Make `make distcheck' work.
3003
3004 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3005 system.h which uses libgettext.h.
3006
3007 2001-12-15 Akim Demaille <akim@epita.fr>
3008
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.
3013
3014 2001-12-15 Akim Demaille <akim@epita.fr>
3015
3016 The header can also be produced directly, without any obstack!
3017 Yahoo!
3018
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
3024 anyway.
3025 (output_token_translations): Merge into...
3026 (symbols_output): this.
3027 Rename as...
3028 (symbols_save): this.
3029 (reader): Adjust.
3030 * src/output.c (header_output): New.
3031 (output): Call it.
3032
3033 2001-12-15 Akim Demaille <akim@epita.fr>
3034
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.
3040 Rename as...
3041 (copy_comment): this.
3042
3043 2001-12-15 Akim Demaille <akim@epita.fr>
3044
3045 * src/lex.c, src/lex.h (xgetc): No longer static.
3046 * src/reader.c (parse_union_decl): Revamp.
3047
3048 2001-12-15 Akim Demaille <akim@epita.fr>
3049
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.
3053
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.
3059
3060 2001-12-15 Akim Demaille <akim@epita.fr>
3061
3062 Attach actions to rules, instead of pre-outputting them to
3063 actions_obstack.
3064
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.
3072 (output): Do it.
3073 (prepare): Don't save the `action' muscle.
3074 * src/bison.simple: s/%%action/%%actions/.
3075
3076 2001-12-15 Akim Demaille <akim@epita.fr>
3077
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.
3081
3082 2001-12-14 Akim Demaille <akim@epita.fr>
3083
3084 * src/lex.c (literalchar): Simply return the char you decoded, non
3085 longer mess around with obstacks and int pointers.
3086 Adjust all callers.
3087
3088 2001-12-14 Akim Demaille <akim@epita.fr>
3089
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
3094 token strings.
3095
3096 2001-12-13 Paul Eggert <eggert@twinsun.com>
3097
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.
3102
3103 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3104
3105 2001-12-13 Akim Demaille <akim@epita.fr>
3106
3107 The computation of nullable is broken: it doesn't handle empty
3108 RHS's properly.
3109
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.
3114
3115 Work around Autotest bugs.
3116
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
3123 frames.
3124 Move to...
3125 * tests/sets.at: here.
3126
3127 2001-12-13 Akim Demaille <akim@epita.fr>
3128
3129 * src/closure.c (closure): Use nrules instead of playing tricks
3130 with BITS_PER_WORD.
3131
3132 2001-12-13 Akim Demaille <akim@epita.fr>
3133
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
3136 nonterminal.
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.
3145
3146 2001-12-13 Akim Demaille <akim@epita.fr>
3147
3148 * src/reader.c (readgram): Remove dead code, an strip useless
3149 braces.
3150 (get_type): Remove, unused.
3151
3152 2001-12-12 Akim Demaille <akim@epita.fr>
3153
3154 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
3155 on that of lib/error.c.
3156
3157 2001-12-12 Akim Demaille <akim@epita.fr>
3158
3159 Some hosts don't like `/' in includes.
3160
3161 * src/system.h: Include libgettext.h without qualifying the path.
3162 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
3163 $(top_srcdir).
3164
3165 2001-12-11 Marc Autret <autret_m@epita.fr>
3166
3167 * src/output.c (output_parser): Remove useless muscle.
3168
3169 2001-12-11 Marc Autret <autret_m@epita.fr>
3170
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.
3175
3176 2001-12-10 Marc Autret <autret_m@epita.fr>
3177
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.
3182
3183 2001-12-10 Marc Autret <autret_m@epita.fr>
3184
3185 * src/reader.c (symbols_output): Clean up.
3186 * src/output.c (output_gram, output): Clean up.
3187
3188 2001-12-10 Akim Demaille <akim@epita.fr>
3189
3190 * src/lalr.c (initialize_lookaheads): New. Extracted from...
3191 * src/LR0.c (set_state_table): here.
3192 * src/lalr.c (lalr): Call it.
3193
3194 2001-12-10 Akim Demaille <akim@epita.fr>
3195
3196 * src/state.h (shifts): Remove the `number' member: shifts are
3197 attached to state, hence no longer need to be labelled with a
3198 state number.
3199
3200 2001-12-10 Akim Demaille <akim@epita.fr>
3201
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.
3204
3205 * src/state.h (shifts): Remove the `next' member.
3206 * src/LR0.c (first_state, last_state): Remove.
3207 Adjust the callers.
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.
3212
3213 2001-12-10 Akim Demaille <akim@epita.fr>
3214
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.
3219
3220 2001-12-10 Akim Demaille <akim@epita.fr>
3221
3222 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
3223 only when appropriate: when insert_start_shifting_state' is not
3224 invoked.
3225 * tests/regression.at (Rule Line Numbers): Adjust.
3226
3227 2001-12-10 Akim Demaille <akim@epita.fr>
3228
3229 * src/LR0.c (augment_automaton): Now that all states have shifts,
3230 merge the two cases addition shifts to the initial state.
3231
3232 2001-12-10 Akim Demaille <akim@epita.fr>
3233
3234 * src/lalr.c (set_state_table): Move to...
3235 * src/LR0.c: here.
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.
3239
3240 2001-12-10 Akim Demaille <akim@epita.fr>
3241
3242 * src/LR0.h (first_shift, first_reduction): Remove.
3243 * src/lalr.c: Don't use first_shift: find shifts through the
3244 states.
3245
3246 2001-12-10 Akim Demaille <akim@epita.fr>
3247
3248 * src/LR0.c: Attach shifts to states as soon as they are
3249 computed.
3250 * src/lalr.c (set_state_table): Instead of assigning shifts to
3251 state, just assert that the mapping was properly done.
3252
3253 2001-12-10 Akim Demaille <akim@epita.fr>
3254
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!
3264
3265 2001-12-10 Akim Demaille <akim@epita.fr>
3266
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.
3273 * src/vmsgetargs.c: Vaguely adjust, but who cares?
3274
3275 2001-12-10 Akim Demaille <akim@epita.fr>
3276
3277 * src/muscle_tab.c (muscle_init): NULL is a better default than
3278 `"0"'.
3279
3280 2001-12-10 Akim Demaille <akim@epita.fr>
3281
3282 * src/reader.c (reader): Calling symbols_output once is enough.
3283
3284 2001-12-10 Akim Demaille <akim@epita.fr>
3285
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
3288 member.
3289
3290 * src/state.h (struct reductions): Remove member `number' and
3291 `next'.
3292 * src/LR0.c (first_reduction, last_reduction): Remove.
3293 (save_reductions): Don't link the new reductions, store them in
3294 this_state.
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
3299 members.
3300
3301 2001-12-10 Akim Demaille <akim@epita.fr>
3302
3303 * src/options.c (OPTN, DRTV, BOTH): New.
3304 (option_table): Use them.
3305
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
3309 reasons.
3310
3311 2001-12-10 Akim Demaille <akim@epita.fr>
3312
3313 * src/output.c (output, prepare): Make sure the values of the
3314 muscles `action' and `prologue' are 0-terminated.
3315
3316 2001-12-10 Akim Demaille <akim@epita.fr>
3317
3318 Clean up GCC warnings.
3319
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.
3327
3328 2001-12-10 Akim Demaille <akim@epita.fr>
3329
3330 * configure.in: Require 2.52g.
3331 M4 is not needed, but AUTOM4TE is.
3332 * m4/m4.m4: Remove.
3333 * tests/Makefile.am: Adjust.
3334
3335 2001-12-10 Akim Demaille <akim@epita.fr>
3336
3337 One structure for states is enough, even though theoretically
3338 there are LR(0) states and LALR(1) states.
3339
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
3347 `state_table'.
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.
3350
3351 2001-12-10 Akim Demaille <akim@epita.fr>
3352
3353 Bison dumps core on bash.y.
3354 Reported by Pascal Bart.
3355
3356 * src/warshall.c (bitmatrix_print): New.
3357 (TC): Use it.
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.
3361
3362 2001-12-05 Akim Demaille <akim@epita.fr>
3363
3364 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
3365 its argument.
3366 Reported by Peter Hámorský.
3367
3368 2001-12-05 Akim Demaille <akim@epita.fr>
3369
3370 * src/conflicts.c (err_table): Remove.
3371 (resolve_sr_conflict): Adjust.
3372 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
3373 Rename as...
3374 (state_t.reductions, state_t.shifts): this.
3375
3376 2001-12-05 Akim Demaille <akim@epita.fr>
3377
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.
3384
3385 2001-12-05 Akim Demaille <akim@epita.fr>
3386
3387 * src/output.c (pack_vector): Use assert, not berror.
3388 * src/main.c (berror): Remove, unused.
3389
3390 2001-12-05 Akim Demaille <akim@epita.fr>
3391
3392 New experimental feature: if --verbose --trace output all the
3393 items of a state, not only its kernel.
3394
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.
3399
3400 2001-12-05 Akim Demaille <akim@epita.fr>
3401
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.
3405
3406 2001-12-05 Akim Demaille <akim@epita.fr>
3407
3408 * src/closure.c (print_closure): Improve.
3409 (closure): Use it for printing input and output.
3410
3411 2001-12-05 Akim Demaille <akim@epita.fr>
3412
3413 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
3414 indexed by nonterminals.
3415
3416 2001-12-05 Akim Demaille <akim@epita.fr>
3417
3418 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
3419 what it was!).
3420 * src/warshall.h: Remove accidental duplication of the content.
3421
3422 2001-12-05 Akim Demaille <akim@epita.fr>
3423
3424 * src/closure.c (set_fderives): De-obfuscate.
3425
3426 2001-12-05 Akim Demaille <akim@epita.fr>
3427
3428 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
3429
3430 2001-12-05 Akim Demaille <akim@epita.fr>
3431
3432 * src/closure.c (set_firsts): De-obfuscate.
3433
3434 2001-12-05 Akim Demaille <akim@epita.fr>
3435
3436 * src/output.c (action_row): De-obfuscate
3437 using the good o' techniques: arrays not pointers, variable
3438 locality, BITISSET, RESETBIT etc.
3439
3440 2001-12-05 Akim Demaille <akim@epita.fr>
3441
3442 Pessimize the code to simplify it: from now on, all the states
3443 have a valid SHIFTS, which NSHIFTS is possibly 0.
3444
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.
3449
3450 2001-12-05 Akim Demaille <akim@epita.fr>
3451
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''.
3456
3457 2001-12-05 Akim Demaille <akim@epita.fr>
3458
3459 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
3460 using the good o' techniques: arrays not pointers, variable
3461 locality, BITISSET, RESETBIT etc.
3462
3463 2001-12-05 Akim Demaille <akim@epita.fr>
3464
3465 * src/state.h (SHIFT_SYMBOL): New.
3466 * src/conflicts.c: Use it to deobfuscate.
3467
3468 2001-12-05 Akim Demaille <akim@epita.fr>
3469
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.
3473
3474 2001-12-05 Akim Demaille <akim@epita.fr>
3475
3476 * src/conflicts.c (print_reductions): Arrays, not pointers.
3477 Use BITISSET.
3478
3479 2001-12-05 Akim Demaille <akim@epita.fr>
3480
3481 * src/conflicts.c (print_reductions): Pessimize, but clarify.
3482
3483 2001-12-05 Akim Demaille <akim@epita.fr>
3484
3485 * src/conflicts.c (print_reductions): Improve variable locality.
3486
3487 2001-12-05 Akim Demaille <akim@epita.fr>
3488
3489 * src/conflicts.c (print_reductions): Pessimize, but clarify.
3490
3491 2001-12-05 Akim Demaille <akim@epita.fr>
3492
3493 * src/conflicts.c (print_reductions): Improve variable locality.
3494
3495 2001-12-05 Akim Demaille <akim@epita.fr>
3496
3497 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
3498 * src/lalr.c: Use them.
3499
3500 2001-12-05 Akim Demaille <akim@epita.fr>
3501
3502 * src/LR0.c (augment_automaton): Formatting changes.
3503 Better variable locality.
3504
3505 2001-12-05 Akim Demaille <akim@epita.fr>
3506
3507 * src/lalr.c (matrix_print): New.
3508 (transpose): Use it.
3509 Use arrays instead of pointers.
3510
3511 2001-12-05 Akim Demaille <akim@epita.fr>
3512
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.
3516
3517 2001-12-05 Akim Demaille <akim@epita.fr>
3518
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
3522 deallocation.
3523 Improve variable locality.
3524 Avoid variables used as mere abbreviations.
3525 (compute_lookaheads): Use arrays instead of pointers.
3526
3527 2001-12-05 Akim Demaille <akim@epita.fr>
3528
3529 * src/lalr.c (initialize_F): Improve variable locality.
3530 Avoid variables used as mere abbreviations.
3531
3532 2001-12-05 Akim Demaille <akim@epita.fr>
3533
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.
3538
3539 2001-12-05 Akim Demaille <akim@epita.fr>
3540
3541 * src/lalr.c (traverse): Use arrays instead of pointers.
3542
3543 2001-12-05 Akim Demaille <akim@epita.fr>
3544
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'.
3548
3549 2001-12-05 Akim Demaille <akim@epita.fr>
3550
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
3554 memory allocations.
3555
3556 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
3557 static.
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
3562 given state.
3563 Deobfuscate, i.e., allocate, use and free `symbol_count' here
3564 only, and...
3565 (new_itemsets): Allocate `shift_symbol' here.
3566 (allocate_itemsets): symbol_count includes useless nonterminals.
3567 Make room for them.
3568 (free_storage): Use `free', not `XFREE', for pointers that cannot
3569 be null.
3570
3571 2001-12-05 Akim Demaille <akim@epita.fr>
3572
3573 * src/nullable.c (set_nullable): Deobfuscate the handling of
3574 ritem.
3575 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3576
3577 2001-12-05 Akim Demaille <akim@epita.fr>
3578
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
3584 ritem.
3585
3586 2001-12-04 Paul Eggert <eggert@twinsun.com>
3587
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.
3595
3596 2001-11-30 Akim Demaille <akim@epita.fr>
3597
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.
3605
3606 2001-11-27 Paul Eggert <eggert@twinsun.com>
3607
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.
3616
3617 2001-11-29 Paul Eggert <eggert@twinsun.com>
3618
3619 Name space cleanup in generated parser.
3620
3621 * doc/bison.texinfo (Bison Parser): Discuss system headers
3622 and their effect on the user name space.
3623
3624 * src/bison.simple:
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).
3628
3629 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
3630 on user names when possible.
3631
3632 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
3633 Simplify test for whather <alloca.h> exists.
3634
3635 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
3636
3637 (<stdio.h>): Include if YYDEBUG.
3638
3639 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
3640 ! defined (yyoverflow) && ! defined (yymemcpy).
3641
3642 (yymemcpy, yyparse): Rename local variables as needed so that
3643 they all begin with 'yy'.
3644
3645 (yystrlen, yystpcpy): New functions.

3670
3671 Instead of mapping the LHS of unused rules to -1, keep the LHS

3675 * src/print.c (print_grammar): Adjust.
3676 * src/derives.c (set_derives): Likewise.

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.
3711
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.
3716
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.

4114 (state_t): this structure.
4115 * src/output.c, src/lalr.c, src/print_graph.c, src/conflicts.c:

4145
4146 * tests/calc.at, tests/output.at, tests/regression.at,
4147 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:

4174 braces to pacify GCC's warnings for `if () if () {} else {}'.
4175 * src/lex.c (parse_percent_token): Replace equal_offset with
4176 arg_offset.
4177 arg is const.

5104

5493
5494 2001-03-16 Akim Demaille <akim@epita.fr>
5495

5517
5518 * src/reader.c (gensym): `gensym_count' is your own.

5522 2001-02-08 Akim Demaille <akim@epita.fr>
5523
5524 * src/conflicts.c (conflict_report): Be sure not to append to res
5525 between two calls, which could happen if both first sprintf were

5531 New, from fileutils 4.0.37.
5532 * configure.in: Require Autoconf 2.49c. I took some time before
5533 making this decision. This is the only way out for portability
5534 issues in Bison, it would mean way too much duplicate effort to
5535 import in Bison features implemented in 2.49c since 2.13.
5536 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
5537
5538 2001-02-02 Akim Demaille <akim@epita.fr>

5549 (init_lex): Initialize it. No longer call...
5550 (grow_token_buffer): this. Remove it.

5552
5553 2001-01-19 Akim Demaille <akim@epita.fr>
5554
5555 * src/lex.h: Rename all the tokens:
5556 s/\bENDFILE\b/tok_eof/g;
5557 s/\bIDENTIFIER\b/tok_identifier/g;

5570
5571 * src/lex.c (percent_table): Also accept `%yacc',
5572 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
5573 `%debug'.
5574 Handle the actions for `%semantic_parser' and `%pure_parser' here,
5575 instead of returning a token.
5576 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
5577 * src/reader.c (read_declarations): Adjust.
5578 * src/files.c (open_files): Don't call `compute_base_names', don't
5579 compute `attrsfile' since they depend upon data which might be
5580 *in* the input file now.
5581 (output_files): Do it here.
5582 * src/output.c (output_headers): Document the fact that this patch
5583 introduces a guaranteed SEGV for semantic parsers.
5584 * doc/bison.texinfo: Document them.
5585 * tests/suite.at: Exercise these %options.

5605
5606 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
5607 (copy_dollar): Now that everything uses obstacks, get rid of the
5608 FILE * parameters.
5609
5610 2000-12-20 Akim Demaille <akim@epita.fr>
5611
5612 * src/files.c (open_files): Actually the `.output' file is based

5615

5642 (stringappend): Be just like strcat but allocate.
5643 (base_names): Eve out from open_files.
5644 Try to simplify the rather hairy computation of base_name and
5645 short_base_name.
5646 (open_files): Use it.
5647 * tests/suite.at (Checking output file names): New test.
5648

5684
5685 2000-12-19 Akim Demaille <akim@epita.fr>
5686
5687 * src/files.c (open_files): Yipee! We no longer need all the code

5690 2000-12-19 Akim Demaille <akim@epita.fr>
5691

5720 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
5721 prevents type checking.
5722 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
5723 cast the value to (void *): assigning a `foo *' to a `void *'
5724 variable is valid.

5772 Qualify it `const'.
5773 (obstack_copy, obstack_copy0): Rename the second argument as
5774 `address' for consistency. Qualify it `const'.
5775 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
5776 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
5777 `const' their input argument (`data' or `address').

5936 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
5937 options.
5938
5939 2000-10-02 Akim Demaille <akim@epita.fr>
5940
5941 * src/derives.c, src/print.c, src/reduce.c: To ease the
5942 translation, move some `\n' out of the translated strings.
5943
5944 2000-10-02 Akim Demaille <akim@epita.fr>
5945
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.
5951
5952 * src/getargs.c (getargs): Support `--locations'.
5953 (usage): Report it.
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'.
5959 Sort the options.
5960 * tests/calc.m4: Test it.
5961
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'.
5966
5967 2000-10-02 Akim Demaille <akim@epita.fr>
5968
5969 Also test parse error messages, including with YYERROR_VERBOSE.
5970
5971 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
5972 associative).
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.
5979
5980 2000-10-02 Akim Demaille <akim@epita.fr>
5981
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:
5986
5987 #if YYDEBUG
5988 if (yydebug)
5989 {
5990 ...
5991 }
5992 #endif
5993
5994 into
5995
5996 if (yydebug)
5997 {
5998 ...
5999 }
6000
6001 unfortunately this leads to a CPP conflict when
6002 `--name-prefix=foo' is used since it produces `#define yydebug
6003 foodebug'.
6004
6005 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6006 (YYDPRINTF): New macro.
6007 Spread its use.
6008 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6009 the bison options.
6010 Also test `--verbose', `--defines' and `--name-prefix'.
6011
6012 2000-10-02 Akim Demaille <akim@epita.fr>
6013
6014 Improve the readability of the produced parsers.
6015
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
6020 of its line.
6021 New variable, `number_of_dollar_signs', to check there's exactly
6022 one `$' in the parser skeleton.
6023
6024 2000-10-02 Akim Demaille <akim@epita.fr>
6025
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.
6031
6032 2000-10-02 Akim Demaille <akim@epita.fr>
6033
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'.
6044
6045 2000-10-02 Akim Demaille <akim@epita.fr>
6046
6047 * src/getargs.c (fixed_outfiles): Rename as...
6048 (yaccflag): for consistency and accuracy.
6049 Adjust dependencies.
6050
6051 2000-10-02 Akim Demaille <akim@epita.fr>
6052
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.
6061
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
6064 files.
6065 Adjust dependencies.

6070
6071 Various anti-`extern in *.c' changes.
6072
6073 * src/system.h: Include `assert.h'.
6074
6075 2000-10-02 Akim Demaille <akim@epita.fr>
6076
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'.
6083 Adjust dependencies.
6084

6089 * src/LR0.h: New file.

6101 2000-10-02 Akim Demaille <akim@epita.fr>
6102

6107 * src/conflicts.h: New file.
6108 Propagate its inclusion.
6109

6158 YYDEFACT, that makes it possible for this function to use
6159 output_short_table.
6160
6161 2000-10-02 Akim Demaille <akim@epita.fr>
6162
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
6166 shorts.
6167
6168 * src/reader.c (user_toknums): Be a short table instead of an int
6169 table.
6170 Adjust dependencies.

6177
6178 2000-10-02 Akim Demaille <akim@epita.fr>
6179
6180 * src/output.c (output): Topological sort of the functions, in
6181 order to get rid of the `static' prototypes.

6184 Propagate its inclusion in files explicitly prototyping functions
6185 from output.c.

6207 inclusion.
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
6212 definitions in config.h.
6213
6214 2000-09-20 Akim Demaille <akim@epita.fr>
6215
6216 * src/derives.h: New file.

6374 the file name, not the whole `#line LINE FILE'.
6375
6376 2000-03-17 Akim Demaille <akim@epita.fr>
6377

6416
6417 * src/reader.c (copy_comment): New function, factored out from:
6418 (copy_action): Use it. Removed now unused `match', `ended',
6419 `cplus_comment'.
6420 (copy_guard): Likewise.
6421
6422 2000-03-17 Akim Demaille <akim@epita.fr>
6423

6427
6428 2000-03-17 Akim Demaille <akim@epita.fr>
6429
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).
6435
6436 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
6437 yyval.
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
6446 translators.

6467
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'.
6472
6473 2000-03-16 Akim Demaille <akim@epita.fr>
6474

6511 * m4/Makefile.am (EXTRA_DIST): New variable.
6512 * m4/gettext.m4: New file, from the fileutils.

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.
