ChangeLog

   1 2001-12-29  Akim Demaille  <akim@epita.fr>
   2
   3         Memory leak.
   4
   5         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
   6         since it allocates it for each state, although only one is needed.
   7         (allocate_storage): Do it here.
   8
   9
  10 2001-12-29  Akim Demaille  <akim@epita.fr>
  11
  12         * src/options.h, src/options.c (create_long_option_table): Rename
  13         as...
  14         (long_option_table_new): this, with a clearer prototype.
  15         (percent_table): Remove, unused,
  16         * src/getargs.c (getargs): Adjust.
  17
  18
  19 2001-12-29  Akim Demaille  <akim@epita.fr>
  20
  21         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
  22         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
  23         as states.
  24
  25
  26 2001-12-29  Akim Demaille  <akim@epita.fr>
  27
  28         * src/lalr.c (build_relations): Rename `states' as `states1'.
  29         Sorry, I don't understand exactly what it is, no better name...
  30
  31
  32 2001-12-29  Akim Demaille  <akim@epita.fr>
  33
  34         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
  35         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
  36         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
  37         as rules.
  38
  39
  40 2001-12-29  Akim Demaille  <akim@epita.fr>
  41
  42         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
  43         ago.
  44
  45
  46 2001-12-29  Akim Demaille  <akim@epita.fr>
  47
  48         * src/reader.c, src/reader.h (user_toknums): Remove.
  49         Adjust all users to use symbols[i]->user_token_number.
  50
  51
  52 2001-12-29  Akim Demaille  <akim@epita.fr>
  53
  54         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
  55         Adjust all users to use symbols[i]->prec or ->assoc.
  56
  57
  58 2001-12-29  Akim Demaille  <akim@epita.fr>
  59
  60         * src/reader.c, src/reader.h (tags): Remove.
  61         Adjust all users to use symbols[i]->tag.
  62
  63
  64 2001-12-29  Akim Demaille  <akim@epita.fr>
  65
  66         * src/gram.h, src/gram.c (symbols): New, similar to state_table
  67         and rule_table.
  68         * src/reader.c (packsymbols): Fill this table.
  69         Drop sprec.
  70         * src/conflicts.c (resolve_sr_conflict): Adjust.
  71         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
  72         single table.
  73         Use symbols[i]->tag instead of tags[i].
  74
  75
  76 2001-12-29  Akim Demaille  <akim@epita.fr>
  77
  78         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
  79         In addition, put a comment in there, to replace...
  80         * tests/regression.at (%union and C comments): Remove.
  81
  82
  83 2001-12-29  Akim Demaille  <akim@epita.fr>
  84
  85         * tests/regression.at (Web2c Actions): Blindly move the actual
  86         output as expected output.  The contents *seem* right to me, but I
  87         can't pretend reading perfectly parser tables...  Nonetheless, all
  88         the other tests pass correctly, the table look OK, even though the
  89         presence of `$axiom' is to be noted: AFAICS it is useless (but
  90         harmless).
  91
  92
  93 2001-12-29  Akim Demaille  <akim@epita.fr>
  94
  95         * src/reader.c (readgram): Don't add the rule 0 if there were no
  96         rules read.  In other words, add it _after_ having performed
  97         grammar sanity checks.
  98         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
  99
 100
 101 2001-12-29  Akim Demaille  <akim@epita.fr>
 102
 103         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 104         visible, and some states have now a different number.
 105
 106
 107 2001-12-29  Akim Demaille  <akim@epita.fr>
 108
 109         * src/reader.c (readgram): Bind the initial rule's lineno to that
 110         of the first rule.
 111         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 112         (Solved SR Conflicts): Adjust rule 0's line number.
 113
 114
 115 2001-12-29  Akim Demaille  <akim@epita.fr>
 116
 117         Fix the `GAWK Grammar' failure.
 118
 119         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 120         the reductions of the first state which was mistakenly confused
 121         with the final state because precisely final_state was initialized
 122         to 0.
 123         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 124         now noticed by Bison.
 125         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 126         have a reduction on $default.
 127
 128
 129 2001-12-29  Akim Demaille  <akim@epita.fr>
 130
 131         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 132         rule line numbers.
 133         * src/closure.c (print_closure): Likewise.
 134         * src/derives.c (print_derives): Likewise.
 135         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 136         now.
 137
 138 2001-12-29  Akim Demaille  <akim@epita.fr>
 139
 140         * src/lalr.c (lookaheads_print): New.
 141         (lalr): Call it when --trace-flag.
 142         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 143         are dumped.
 144
 145
 146 2001-12-29  Akim Demaille  <akim@epita.fr>
 147
 148         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 149         when walking through ritem, even via rule->rhs.
 150         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 151         (useful_production, useless_nonterminals): Likewise.
 152         (reduce_grammar_tables): Likewise, plus update nritems.
 153         * src/nullable.c (set_nullable): Likewise.
 154         * src/lalr.c (build_relations): Likewise.
 155         * tests/sets.at (Nullable): Adjust.
 156         Fortunately, now, the $axiom is no longer nullable.
 157
 158
 159 2001-12-29  Akim Demaille  <akim@epita.fr>
 160
 161         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 162         the 0-sentinel.
 163         * src/gram.c (ritem_longest_rhs): Likewise.
 164         * src/reduce.c (nonterminals_reduce): Likewise.
 165         * src/print_graph.c (print_graph): Likewise.
 166         * src/output.c (output_rule_data): Likewise.
 167         * src/nullable.c (set_nullable):  Likewise.
 168
 169 2001-12-29  Akim Demaille  <akim@epita.fr>
 170
 171         * src/output.c: Comment changes.
 172
 173 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 174
 175         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 176         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 177         Sparc, as they were causing more porting problems than the
 178         (minor) performance improvement was worth.
 179
 180         Also, catch up with 1.31's YYSTD.
 181
 182 2001-12-27  Akim Demaille  <akim@epita.fr>
 183
 184         * src/output.c (output_gram): Rely on nritems, not the
 185         0-sentinel.  See below.
 186         Use -1 as separator, not 0.
 187         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 188         Rely on -1 as separator in yyrhs, instead of 0.
 189         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 190         twice `Now at end of input', therefore there are two lines less to
 191         expect.
 192
 193 2001-12-27  Akim Demaille  <akim@epita.fr>
 194
 195         * tests/regression.at (Unresolved SR Conflicts):
 196         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 197         below.
 198
 199 2001-12-27  Akim Demaille  <akim@epita.fr>
 200
 201         * src/LR0.c (new_state): Recognize the final state by the fact it
 202         is reached by eoftoken.
 203         (insert_start_shifting_state, insert_eof_shifting_state)
 204         (insert_accepting_state, augment_automaton): Remove, since now
 205         these states are automatically computed from the initial state.
 206         (generate_states): Adjust.
 207         * src/print.c: When reporting a rule number to the user, substract
 208         1, so that the axiom rule is rule 0, and the first user rule is 1.
 209         * src/reduce.c: Likewise.
 210         * src/print_graph.c (print_core): For the time being, just as for
 211         the report, depend upon --trace-flags to dump the full set of
 212         items.
 213         * src/reader.c (readgram): Once the grammar read, insert the rule
 214         0: `$axiom: START-SYMBOL $'.
 215         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 216         number of the states has changed (the final state is no longer
 217         necessarily the last), catch up.
 218
 219 2001-12-27  Akim Demaille  <akim@epita.fr>
 220
 221         Try to make the use of the eoftoken valid.  Given that its value
 222         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 223         is used instead of > 0 where appropriate, (ii), depend upon nritems
 224         instead of the 0-sentinel.
 225
 226         * src/gram.h, src/gram.c (nritems): New.
 227         Expected to be duplication of nitems, but for the time being...
 228         * src/reader.c (packgram): Assert nritems and nitems are equal.
 229         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 230         * src/closure.c (print_closure, print_fderives): Likewise.
 231         * src/gram.c (ritem_print): Likewise.
 232         * src/print.c (print_core, print_grammar): Likewise.
 233         * src/print_graph.c: Likewise.
 234
 235 2001-12-27  Akim Demaille  <akim@epita.fr>
 236
 237         * src/main.c (main): If there are complains after grammar
 238         reductions, then output the report anyway if requested, then die.
 239         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 240         * src/reader.c (eoftoken): New.
 241         (parse_token_decl): If the token being defined has value `0', it
 242         is the eoftoken.
 243         (packsymbols): No longer hack `tags' to insert `$' by hand.
 244         Be sure to preserve the value of the eoftoken.
 245         (reader): Make sure eoftoken is defined.
 246         Initialize nsyms to 0: now eoftoken is created just like the others.
 247         * src/print.c (print_grammar): Don't special case the eof token.
 248         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 249         lie anyway, albeit pleasant.
 250         * tests/calc.at: Exercise error messages with eoftoken.
 251         Change the grammar so that empty input is invalid.
 252         Adjust expectations.
 253         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 254
 255 2001-12-27  Akim Demaille  <akim@epita.fr>
 256
 257         * configure.in: Check the protos of strchr ans strspn.
 258         Replace strchr if needed.
 259         * src/system.h: Provide the protos of strchr, strspn and memchr if
 260         missing.
 261         * lib/strchr.c: New.
 262         * src/reader.c (symbols_save): Use strchr.
 263
 264 2001-12-27  Akim Demaille  <akim@epita.fr>
 265
 266         * src/print.c, src/print_graph.c (escape): New.
 267         Use it to quote the TAGS outputs.
 268         * src/print_graph.c (print_state): Now errors are in red, and
 269         reductions in green.
 270         Prefer high to wide: output the state number on a line of its own.
 271
 272 2001-12-27  Akim Demaille  <akim@epita.fr>
 273
 274         * src/state.h, src/state.c (reductions_new): New.
 275         * src/LR0.c (set_state_table): Let all the states have a
 276         `reductions', even if reduced to 0.
 277         (save_reductions): Adjust.
 278         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 279         * src/print.c (print_reductions, print_actions): Adjust.
 280         * src/output.c (action_row): Adjust.
 281
 282 2001-12-27  Akim Demaille  <akim@epita.fr>
 283
 284         * src/state.h, src/state.c (errs_new, errs_dup): New.
 285         * src/LR0.c (set_state_table): Let all the states have an errs,
 286         even if reduced to 0.
 287         * src/print.c (print_errs, print_reductions): Adjust.
 288         * src/output.c (output_actions, action_row): Adjust.
 289         * src/conflicts.c (resolve_sr_conflict): Adjust.
 290
 291 2001-12-27  Akim Demaille  <akim@epita.fr>
 292
 293         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 294
 295 2001-12-27  Akim Demaille  <akim@epita.fr>
 296
 297         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 298         * src/print.c: here.
 299         (lookaheadset, shiftset): New, used as additional storage by
 300         print_reductions.
 301         (print_results): Adjust.
 302         (print_shifts, print_gotos, print_errs): New, extracted from...
 303         (print_actions): here.
 304         * src/print_graph.c (print_actions): Remove dead code.
 305
 306 2001-12-27  Akim Demaille  <akim@epita.fr>
 307
 308         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 309         `$n' and `@n'.
 310
 311 2001-12-27  Akim Demaille  <akim@epita.fr>
 312
 313         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 314         (build_relations): Adjust.
 315
 316 2001-12-27  Akim Demaille  <akim@epita.fr>
 317
 318         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 319         duplication.
 320
 321 2001-12-27  Akim Demaille  <akim@epita.fr>
 322
 323         * src/reader.c (packgram): Catch nitems overflows.
 324
 325 2001-12-27  Akim Demaille  <akim@epita.fr>
 326
 327         * src/files.c, src/files.h (guard_obstack): Remove.
 328         * src/output.c (output): Adjust.
 329         * src/reader.c (parse_braces): New, factoring...
 330         (copy_action, copy_guard): these two which are renamed as...
 331         (parse_action, parse_guard): these.
 332         As a voluntary consequence, using braces around guards is now
 333         mandatory.
 334
 335 2001-12-27  Akim Demaille  <akim@epita.fr>
 336
 337         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 338         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 339         members.
 340         (symbol_list_new): Adjust.
 341         (copy_action): action_line is the first line, not the last.
 342         (copy_guard): Just as for actions, store the `action' only, not
 343         the switch/case/break flesh.
 344         Don't parse the user action that might follow the guard, let...
 345         (readgram): do it, i.e., now, there can be an action after a
 346         guard.
 347         In other words the guard is just explicitly optional.
 348         (packgram): Adjust.
 349         * src/output.c (guards_output): New.
 350         (output_parser): Call it when needed.
 351         (output): Also free the guard and attrs obstacks.
 352         * src/files.c, src/files.h (obstack_save): Remove.
 353         (output_files): Remove.
 354         As a result, if one needs the former `.act' file, using an
 355         appropriate skeleton which requires actions and guards is now
 356         required.
 357         * src/main.c (main): Adjust.
 358         * tests/semantic.at: New.
 359         * tests/regression.at: Use `input.y' as input file name.
 360         Avoid 8+3 problems by requiring input.c when the test needs the
 361         parser.
 362
 363 2001-12-27  Akim Demaille  <akim@epita.fr>
 364
 365         * src/reader.c (symbol_list_new): Be sure to initialize all the

 369
 370         All the hacks using a final pseudo state are now useless.
 371
 372         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 373         * src/lalr.c (nLA): New.
 374         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 375         instead of lookaheadsp from the pseudo state (nstate + 1).
 376
 377 2001-12-27  Akim Demaille  <akim@epita.fr>
 378
 379         * src/output.c (action_row, token_actions): Use a state_t instead
 380         of a integer, and nlookaheads instead of the following state's
 381         lookaheadsp.
 382
 383 2001-12-27  Akim Demaille  <akim@epita.fr>
 384
 385         * src/conflicts.c (log_resolution, flush_shift)
 386         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 387         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 388         (conflicts_print, print_reductions): Use a state_t instead of an
 389         integer when referring to a state.
 390         As much as possible, depend upon nlookaheads, instead of the
 391         `lookaheadsp' member of the following state (since lookaheads of
 392         successive states are successive, the difference between state n + 1
 393         and n served as the number of lookaheads for state n).
 394         * src/lalr.c (add_lookback_edge): Likewise.
 395         * src/print.c (print_core, print_actions, print_state)
 396         (print_results): Likewise.
 397         * src/print_graph.c (print_core, print_actions, print_state)
 398         (print_graph): Likewise.
 399         * src/conflicts.h: Adjust.
 400
 401 2001-12-27  Akim Demaille  <akim@epita.fr>
 402
 403         * src/bison.hairy: Formatting/comment changes.
 404         ANSIfy.
 405         Remove `register' indications.
 406         Add plenty of `static'.
 407
 408 2001-12-27  Akim Demaille  <akim@epita.fr>
 409
 410         * src/output.c (prepare): Drop the muscle `ntbase' which
 411         duplicates ntokens.
 412         * src/bison.simple: Formatting/comment changes.
 413         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 414         is an undocumented synonym.
 415
 416 2001-12-22  Akim Demaille  <akim@epita.fr>
 417
 418         * src/output.c (output_table_data): Change the prototype to use
 419         `int' for array ranges: some invocations do pass an int, not a
 420         short.
 421         Reported by Wayne Green.
 422
 423 2001-12-22  Akim Demaille  <akim@epita.fr>
 424
 425         Some actions of web2c.y are improperly triggered.
 426         Reported by Mike Castle.
 427
 428         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 429         * tests/regression.at (Web2c): Rename as...
 430         (Web2c Report): this.
 431         (Web2c Actions): New.
 432
 433 2001-12-22  Akim Demaille  <akim@epita.fr>
 434
 435         Reductions in web2c.y are improperly reported.
 436         Reported by Mike Castle.
 437
 438         * src/conflicts.c (print_reductions): Fix.
 439         * tests/regression.at (Web2c): New.
 440
 441 2001-12-18  Akim Demaille  <akim@epita.fr>
 442
 443         Some host fail on `assert (!"foo")', which expands to
 444         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 445         Reported by Nelson Beebee.
 446
 447         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 448         `#define it_succeeded 0' and `assert (it_succeeded)'.
 449
 450 2001-12-17  Marc Autret  <autret_m@epita.fr>
 451
 452         * src/bison.simple: Don't hard code the skeleton line and filename.
 453         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 454         New line counter 'skeleton_line' (skeleton-line muscle).
 455
 456 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 457
 458         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 459         YYDEBUG must be defined to a nonzero value.
 460
 461         * src/bison.simple (yytname): Do not assume that the user defines
 462         YYDEBUG to a properly parenthesized expression.
 463
 464 2001-12-17  Akim Demaille  <akim@epita.fr>
 465
 466         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 467         nlookaheads is a new member.
 468         Adjust all users.
 469         * src/lalr.h (nlookaheads): Remove this orphan declaration.
 470         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 471         state.
 472
 473 2001-12-17  Akim Demaille  <akim@epita.fr>
 474
 475         * src/files.h, src/files.c (open_files, close_files): Remove.
 476         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 477         let...
 478         * src/reader.c (reader): Do it.
 479
 480 2001-12-17  Akim Demaille  <akim@epita.fr>
 481
 482         * src/conflicts.c (print_reductions): Formatting changes.
 483
 484 2001-12-17  Akim Demaille  <akim@epita.fr>
 485
 486         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 487         (flush_reduce): New.
 488         (resolve_sr_conflict): Adjust.
 489
 490 2001-12-17  Akim Demaille  <akim@epita.fr>
 491
 492         * src/output.c (output_obstack): Be static and rename as...
 493         (format_obstack): this, to avoid any confusion with files.c's
 494         output_obstack.
 495         * src/reader.h (muscle_obstack): Move to...
 496         * src/output.h: here, since it's defined in output.c.
 497
 498 2001-12-17  Akim Demaille  <akim@epita.fr>
 499
 500         * src/output.c (action_row, save_column, default_goto)
 501         (sort_actions, matching_state, pack_vector): Better variable
 502         locality.
 503
 504 2001-12-17  Akim Demaille  <akim@epita.fr>
 505
 506         * src/output.c: Various formatting changes.
 507
 508 2001-12-17  Akim Demaille  <akim@epita.fr>
 509
 510         * src/files.c (output_files): Free the output_obstack.
 511         * src/main.c (main): Call print and print_graph conditionally.
 512         * src/print.c (print): Work unconditionally.
 513         * src/print_graph.c (print_graph): Work unconditionally.
 514         * src/conflicts.c (log_resolution): Output only if verbose_flag.
 515
 516 2001-12-16  Marc Autret  <autret_m@epita.fr>
 517
 518         * src/output.c (actions_output): Fix. When we use %no-lines,
 519         there is one less line per action.
 520
 521 2001-12-16  Marc Autret  <autret_m@epita.fr>
 522
 523         * src/bison.simple: Remove a useless #line directive.
 524         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 525         * src/output.c (get_lines_number): New.
 526         (output_parser): Adjust, now takes care about the lines of a
 527         output muscles.
 528         Fix line numbering.
 529         (actions_output): Computes the number of lines taken by actions.
 530         (output_master_parser): Insert new skeleton which is the name of
 531         the output parser file name.
 532
 533 2001-12-15  Marc Autret  <autret_m@epita.fr>
 534
 535         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
 536
 537 2001-12-15  Marc Autret  <autret_m@epita.fr>
 538
 539         * src/output.c (output_gram): Keep track of the hairy one.
 540
 541 2001-12-15  Akim Demaille  <akim@epita.fr>
 542
 543         Make `make distcheck' work.
 544
 545         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 546         system.h which uses libgettext.h.
 547
 548 2001-12-15  Akim Demaille  <akim@epita.fr>
 549
 550         * src/nullable.c (set_nullable): Useless rules must be skipped,
 551         otherwise, since we range over their symbols, we might look at a
 552         nonterminal which no longer ``exists'', i.e., it is not counted in
 553         `nvars', hence we overflow our arrays.
 554
 555 2001-12-15  Akim Demaille  <akim@epita.fr>
 556
 557         The header can also be produced directly, without any obstack!
 558         Yahoo!
 559
 560         * src/files.c, src/files.h (defines_obstack): Remove.
 561         (compute_header_macro): Global.
 562         (defines_obstack_save): Remove.
 563         * src/reader.c (parse_union_decl): No longer output to
 564         defines_obstack: its content can be found in the `stype' muscle
 565         anyway.
 566         (output_token_translations): Merge into...
 567         (symbols_output): this.
 568         Rename as...
 569         (symbols_save): this.
 570         (reader): Adjust.
 571         * src/output.c (header_output): New.
 572         (output): Call it.
 573
 574 2001-12-15  Akim Demaille  <akim@epita.fr>
 575
 576         * src/reader.c (parse_union_decl): Instead of handling two obstack
 577         simultaneously, use one to define the `stype' muscle, and use the
 578         value of the latter to fill defines_obstack.
 579         (copy_comment): Remove.
 580         (copy_comment2): Work for a single obstack.
 581         Rename as...
 582         (copy_comment): this.
 583
 584 2001-12-15  Akim Demaille  <akim@epita.fr>
 585
 586         * src/lex.c, src/lex.h (xgetc): No longer static.
 587         * src/reader.c (parse_union_decl): Revamp.
 588
 589 2001-12-15  Akim Demaille  <akim@epita.fr>
 590
 591         Still making progress in separating Bison into (i) input, (ii)
 592         process, (iii) output: now we can directly output the parser file
 593         without using table_obstack at all.
 594
 595         * src/files.c, src/files.h (table_obstack): Bye bye.
 596         (parser_file_name): New.
 597         * src/files.c (compute_output_file_names): Compute it.
 598         * src/output.c (actions_output, output_parser)
 599         (output_master_parser): To a file instead of an obstack.
 600
 601 2001-12-15  Akim Demaille  <akim@epita.fr>
 602
 603         Attach actions to rules, instead of pre-outputting them to
 604         actions_obstack.
 605
 606         * src/gram.h (rule_t): action and action_line are new members.
 607         * src/reader.c (symbol_list): Likewise.
 608         (copy_action): Save the actions within the rule.
 609         (packgram): Save them in rule_table.
 610         * src/output.c (actions_output): New.
 611         (output_parser): Use it on `%%actions'.
 612         (output_rule_data): Don't free rule_table.
 613         (output): Do it.
 614         (prepare): Don't save the `action' muscle.
 615         * src/bison.simple: s/%%action/%%actions/.
 616
 617 2001-12-15  Akim Demaille  <akim@epita.fr>
 618
 619         * src/reader.c (copy_action): When --yacc, don't append a `;'
 620         to the user action: let it fail if lacking.
 621         Suggested by Arnold Robbins and Tom Tromey.
 622
 623 2001-12-14  Akim Demaille  <akim@epita.fr>
 624
 625         * src/lex.c (literalchar): Simply return the char you decoded, non
 626         longer mess around with obstacks and int pointers.
 627         Adjust all callers.
 628
 629 2001-12-14  Akim Demaille  <akim@epita.fr>
 630
 631         * src/lex.c (literalchar): Don't escape the special characters,
 632         just decode them, and keep them as char (before, eol was output as
 633         the 2 char string `\n' etc.).
 634         * src/output.c (output_rule_data): Use quotearg to output the
 635         token strings.
 636
 637 2001-12-13  Paul Eggert  <eggert@twinsun.com>
 638
 639         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
 640         Do not infringe on the global user namespace when using C++.
 641         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
 642         All uses of `fprintf' and `stderr' changed.
 643
 644         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
 645
 646 2001-12-13  Akim Demaille  <akim@epita.fr>
 647
 648         The computation of nullable is broken: it doesn't handle empty
 649         RHS's properly.
 650
 651         * tests/torture.at (GNU AWK Grammar): New.
 652         * tests/sets.at (Nullable): New.
 653         * src/nullable.c (set_nullable): Instead of blindly looping over
 654         `ritems', loop over the rules, and then over their rhs's.
 655
 656         Work around Autotest bugs.
 657
 658         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
 659         frame, because Autotest understand lines starting with a `+' as
 660         traces from the shell.  Then, they are not processed properly.
 661         Admittedly an Autotest bug, but we don't have time to wait for
 662         Autotest to catch up.
 663         * tests/regression.at (Broken Closure): Adjust to the new table
 664         frames.
 665         Move to...
 666         * tests/sets.at: here.
 667
 668 2001-12-13  Akim Demaille  <akim@epita.fr>
 669
 670         * src/closure.c (closure): Use nrules instead of playing tricks
 671         with BITS_PER_WORD.
 672
 673 2001-12-13  Akim Demaille  <akim@epita.fr>
 674
 675         * src/print.c (print_actions): Output the handling of `$' as the
 676         traces do: shifting the token EOF.  Before EOF was treated as a
 677         nonterminal.
 678         * tests/regression.at: Adjust some tests.
 679         * src/print_graph.c (print_core): Complete the set of items via
 680         closure.  The next-to-final and final states are still unsatisfying,
 681         but that's to be addressed elsewhere.
 682         No longer output the rule numbers, but do output the state number.
 683         A single loop for the shifts + gotos is enough, but picked a
 684         distinct color for each.
 685         (print_graph): Initialize and finalize closure.
 686
 687 2001-12-13  Akim Demaille  <akim@epita.fr>
 688
 689         * src/reader.c (readgram): Remove dead code, an strip useless
 690         braces.
 691         (get_type): Remove, unused.
 692
 693 2001-12-12  Akim Demaille  <akim@epita.fr>
 694
 695         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 696         on that of lib/error.c.
 697
 698 2001-12-12  Akim Demaille  <akim@epita.fr>
 699
 700         Some hosts don't like `/' in includes.
 701
 702         * src/system.h: Include libgettext.h without qualifying the path.
 703         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 704         $(top_srcdir).
 705
 706 2001-12-11  Marc Autret  <autret_m@epita.fr>
 707
 708         * src/output.c (output_parser): Remove useless muscle.
 709
 710 2001-12-11  Marc Autret  <autret_m@epita.fr>
 711
 712         * src/bison.simple: Remove #line just before %%epilogue. It
 713         is now handled in ...
 714         * src/reader.c (read_additionnal_code): Add the output of a
 715         #line for the epilogue.
 716
 717 2001-12-10  Marc Autret  <autret_m@epita.fr>
 718
 719         * src/reader.c (copy_definition): Re-use CPP-outed code which
 720         replace precedent remove.
 721         * src/bison.simple: Remove #line before %%prologue because
 722         %%input-line is wrong at this time.
 723
 724 2001-12-10  Marc Autret  <autret_m@epita.fr>
 725
 726         * src/reader.c (symbols_output): Clean up.
 727         * src/output.c (output_gram, output): Clean up.
 728
 729 2001-12-10  Akim Demaille  <akim@epita.fr>
 730
 731         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 732         * src/LR0.c (set_state_table): here.
 733         * src/lalr.c (lalr): Call it.
 734
 735 2001-12-10  Akim Demaille  <akim@epita.fr>
 736
 737         * src/state.h (shifts): Remove the `number' member: shifts are
 738         attached to state, hence no longer need to be labelled with a
 739         state number.
 740
 741 2001-12-10  Akim Demaille  <akim@epita.fr>
 742
 743         Now that states have a complete set of members, the linked list of
 744         shifts is useless: just fill directly the state's shifts member.
 745
 746         * src/state.h (shifts): Remove the `next' member.
 747         * src/LR0.c (first_state, last_state): Remove.
 748         Adjust the callers.
 749         (augment_automaton): Don't look for the shifts that must be added
 750         a shift on EOF: it is those of the state we looked for!  But now,
 751         since shifts are attached, it is no longer needed to looking
 752         merely by its id: its number.
 753
 754 2001-12-10  Akim Demaille  <akim@epita.fr>
 755
 756         * src/LR0.c (augment_automaton): Better variable locality.
 757         Remove an impossible branch: if there is a state corresponding to
 758         the start symbol being shifted, then there is shift for the start
 759         symbol from the initial state.
 760
 761 2001-12-10  Akim Demaille  <akim@epita.fr>
 762
 763         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 764         only when appropriate: when insert_start_shifting_state' is not
 765         invoked.
 766         * tests/regression.at (Rule Line Numbers): Adjust.
 767
 768 2001-12-10  Akim Demaille  <akim@epita.fr>
 769
 770         * src/LR0.c (augment_automaton): Now that all states have shifts,
 771         merge the two cases addition shifts to the initial state.
 772
 773 2001-12-10  Akim Demaille  <akim@epita.fr>
 774
 775         * src/lalr.c (set_state_table): Move to...
 776         * src/LR0.c: here.
 777         * src/lalr.c (lalr): Don't call it...
 778         * src/LR0.c (generate_states): do it.
 779         * src/LR0.h (first_state): Remove, only the table is used.
 780
 781 2001-12-10  Akim Demaille  <akim@epita.fr>
 782
 783         * src/LR0.h (first_shift, first_reduction): Remove.
 784         * src/lalr.c: Don't use first_shift: find shifts through the
 785         states.
 786
 787 2001-12-10  Akim Demaille  <akim@epita.fr>
 788
 789         * src/LR0.c: Attach shifts to states as soon as they are
 790         computed.
 791         * src/lalr.c (set_state_table): Instead of assigning shifts to
 792         state, just assert that the mapping was properly done.
 793
 794 2001-12-10  Akim Demaille  <akim@epita.fr>
 795
 796         * src/LR0.c (insert_start_shift): Rename as...
 797         (insert_start_shifting_state): this.
 798         (insert_eof_shifting_state, insert_accepting_state): New.
 799         (augment_automaton): Adjust.
 800         Better locality of the variables.
 801         When looking if the start_symbol is shifted from the initial
 802         state, using `while (... symbol != start_symbol ...)' sounds
 803         better than `while (... symbol < start_symbol ...)': If fail
 804         to see how the order between symbols could be relevant!
 805
 806 2001-12-10  Akim Demaille  <akim@epita.fr>
 807
 808         * src/getargs.h: Don't declare `spec_name_prefix' and
 809         `spec_file_prefix', declared by src/files.h.
 810         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 811         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 812         * src/output.c (prepare): Adjust.
 813         * src/reader.c (symbols_output): Likewise.
 814         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 815
 816 2001-12-10  Akim Demaille  <akim@epita.fr>
 817
 818         * src/muscle_tab.c (muscle_init): NULL is a better default than
 819         `"0"'.
 820
 821 2001-12-10  Akim Demaille  <akim@epita.fr>
 822
 823         * src/reader.c (reader): Calling symbols_output once is enough.
 824
 825 2001-12-10  Akim Demaille  <akim@epita.fr>
 826
 827         Now that states have a complete set of members, the linked list of
 828         reductions is useless: just fill directly the state's reductions
 829         member.
 830
 831         * src/state.h (struct reductions): Remove member `number' and
 832         `next'.
 833         * src/LR0.c (first_reduction, last_reduction): Remove.
 834         (save_reductions): Don't link the new reductions, store them in
 835         this_state.
 836         * src/lalr.c (set_state_table): No need to attach reductions to
 837         states, it's already done.
 838         * src/output.c (output_actions): No longer free the shifts, then
 839         the reductions, then the states: free all the states and their
 840         members.
 841
 842 2001-12-10  Akim Demaille  <akim@epita.fr>
 843
 844         * src/options.c (OPTN, DRTV, BOTH): New.
 845         (option_table): Use them.
 846
 847         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 848         the job of system.h.
 849         * src/options.c: Don't include stdio.h and xalloc.h for the same
 850         reasons.
 851
 852 2001-12-10  Akim Demaille  <akim@epita.fr>
 853
 854         * src/output.c (output, prepare): Make sure the values of the
 855         muscles `action' and `prologue' are 0-terminated.
 856
 857 2001-12-10  Akim Demaille  <akim@epita.fr>
 858
 859         Clean up GCC warnings.
 860
 861         * src/reader.c (copy_action): `buf' is not used.
 862         (parse_skel_decl): Be static.
 863         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 864         * src/options.h (create_long_option_table): Have a real prototype.
 865         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 866         (hash_delete_at): Return const void *.
 867         Adjust casts to preserve the const.
 868
 869 2001-12-10  Akim Demaille  <akim@epita.fr>
 870
 871         * configure.in: Require 2.52g.
 872         M4 is not needed, but AUTOM4TE is.
 873         * m4/m4.m4: Remove.
 874         * tests/Makefile.am: Adjust.
 875
 876 2001-12-10  Akim Demaille  <akim@epita.fr>
 877
 878         One structure for states is enough, even though theoretically
 879         there are LR(0) states and LALR(1) states.
 880
 881         * src/lalr.h (state_t): Remove.
 882         (state_table): Be state_t **, not state_t *.
 883         * src/state.h (core, CORE_ALLOC): Rename as...
 884         (state_t, STATE_ALLOC): this.
 885         Add the LALR(1) members: shifts, reductions, errs.
 886         * src/LR0.c (state_table): Rename as...
 887         (state_hash): this, to avoid name clashes with the global
 888         `state_table'.
 889         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 890         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 891
 892 2001-12-10  Akim Demaille  <akim@epita.fr>
 893
 894         Bison dumps core on bash.y.
 895         Reported by Pascal Bart.
 896
 897         * src/warshall.c (bitmatrix_print): New.
 898         (TC): Use it.
 899         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 900         j must be the outer loop.
 901         * tests/regression.at (Broken Closure): New.
 902
 903 2001-12-05  Akim Demaille  <akim@epita.fr>
 904
 905         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 906         its argument.
 907         Reported by Peter Hámorský.
 908
 909 2001-12-05  Akim Demaille  <akim@epita.fr>

 913         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 914         Rename as...
 915         (state_t.reductions, state_t.shifts): this.
 916
 917 2001-12-05  Akim Demaille  <akim@epita.fr>
 918
 919         * src/reduce.c (reduce_grammar_tables): No longer disable the
 920         removal of useless rules via CPP but via `if (0)', so that the
 921         compiler still check the code is valid.
 922         For instance, it should have noticed `rline' no longer exists: use
 923         the `line' member of rule_t.
 924         * src/gram.c (dummy, rline): Remove, unused.
 925
 926 2001-12-05  Akim Demaille  <akim@epita.fr>
 927
 928         * src/output.c (pack_vector): Use assert, not berror.
 929         * src/main.c (berror): Remove, unused.
 930
 931 2001-12-05  Akim Demaille  <akim@epita.fr>
 932
 933         New experimental feature: if --verbose --trace output all the
 934         items of a state, not only its kernel.
 935
 936         * src/print.c (print_core): If `trace_flag', then invoke closure
 937         before outputting the items of the state (print_core is no longer
 938         a correct name them).
 939         (print_results): Invoke new_closure/free_closure if needed.
 940
 941 2001-12-05  Akim Demaille  <akim@epita.fr>
 942
 943         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 944         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 945         (nitemset): for consistency with the rest of the project.
 946
 947 2001-12-05  Akim Demaille  <akim@epita.fr>
 948
 949         * src/closure.c (print_closure): Improve.
 950         (closure): Use it for printing input and output.
 951
 952 2001-12-05  Akim Demaille  <akim@epita.fr>
 953
 954         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 955         indexed by nonterminals.
 956
 957 2001-12-05  Akim Demaille  <akim@epita.fr>
 958
 959         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 960         what it was!).
 961         * src/warshall.h: Remove accidental duplication of the content.
 962
 963 2001-12-05  Akim Demaille  <akim@epita.fr>
 964
 965         * src/closure.c (set_fderives): De-obfuscate.

 974
 975 2001-12-05  Akim Demaille  <akim@epita.fr>
 976
 977         * src/output.c (action_row): De-obfuscate
 978         using the good o' techniques: arrays not pointers, variable
 979         locality, BITISSET, RESETBIT etc.
 980
 981 2001-12-05  Akim Demaille  <akim@epita.fr>
 982
 983         Pessimize the code to simplify it: from now on, all the states
 984         have a valid SHIFTS, which NSHIFTS is possibly 0.
 985
 986         * src/LR0.c (shifts_new): Be global and move to..
 987         * src/state.c, src/state.h: here.
 988         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 989         * src/print_graph: Adjust.

 991 2001-12-05  Akim Demaille  <akim@epita.fr>
 992
 993         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 994         * src/conflicts.c: Use it.
 995         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 996         incorrectly ``simplified''.
 997
 998 2001-12-05  Akim Demaille  <akim@epita.fr>
 999
1000         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1001         using the good o' techniques: arrays not pointers, variable
1002         locality, BITISSET, RESETBIT etc.
1003
1004 2001-12-05  Akim Demaille  <akim@epita.fr>
1005
1006         * src/state.h (SHIFT_SYMBOL): New.
1007         * src/conflicts.c: Use it to deobfuscate.
1008
1009 2001-12-05  Akim Demaille  <akim@epita.fr>
1010
1011         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1012         (print_reductions): De-obfuscate using the good o' techniques:
1013         arrays not pointers, variable locality, BITISSET.
1014
1015 2001-12-05  Akim Demaille  <akim@epita.fr>
1016
1017         * src/conflicts.c (print_reductions): Arrays, not pointers.

1019
1020 2001-12-05  Akim Demaille  <akim@epita.fr>
1021

1023
1024 2001-12-05  Akim Demaille  <akim@epita.fr>
1025

1029

1040
1041 2001-12-05  Akim Demaille  <akim@epita.fr>
1042
1043         * src/LR0.c (augment_automaton): Formatting changes.
1044         Better variable locality.
1045
1046 2001-12-05  Akim Demaille  <akim@epita.fr>
1047
1048         * src/lalr.c (matrix_print): New.
1049         (transpose): Use it.
1050         Use arrays instead of pointers.
1051
1052 2001-12-05  Akim Demaille  <akim@epita.fr>
1053
1054         * src/lalr.c (maxrhs): Move to...
1055         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1056         * src/lalr.c (build_relations): Adjust.
1057
1058 2001-12-05  Akim Demaille  <akim@epita.fr>
1059
1060         * src/lalr.c (transpose): Free the memory allocated to the
1061         argument, as it is replaced by the results by the unique caller.
1062         (build_relations): Merely invoke transpose: it handles the memory
1063         deallocation.
1064         Improve variable locality.
1065         Avoid variables used as mere abbreviations.
1066         (compute_lookaheads): Use arrays instead of pointers.
1067
1068 2001-12-05  Akim Demaille  <akim@epita.fr>
1069
1070         * src/lalr.c (initialize_F): Improve variable locality.

1072
1073 2001-12-05  Akim Demaille  <akim@epita.fr>
1074
1075         * src/derives.c (print_derives): Display the ruleno.
1076         * src/lalr.c (initialize_F, transpose): Better variable locality
1077         to improve readability.
1078         Avoid variables used as mere abbreviations.
1079
1080 2001-12-05  Akim Demaille  <akim@epita.fr>
1081
1082         * src/lalr.c (traverse): Use arrays instead of pointers.
1083
1084 2001-12-05  Akim Demaille  <akim@epita.fr>
1085
1086         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1087         the handling of squeue.
1088         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1089
1090 2001-12-05  Akim Demaille  <akim@epita.fr>
1091
1092         Because useless nonterminals are now kept alive (instead of being
1093         `destroyed'), we now sometimes examine them, and store information
1094         related to them.  Hence we need to know their number, and adjust
1095         memory allocations.
1096
1097         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1098         static.
1099         * src/LR0.c (allocate_itemsets): The memory allocated to
1100         `symbol_count' was used for two different purpose: once to count
1101         the number of occurrences of each symbol, and later reassigned to
1102         `shift_symbol', containing the symbol that can be shifted from a
1103         given state.
1104         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1105         only, and...
1106         (new_itemsets): Allocate `shift_symbol' here.
1107         (allocate_itemsets): symbol_count includes useless nonterminals.
1108         Make room for them.
1109         (free_storage): Use `free', not `XFREE', for pointers that cannot
1110         be null.

1113
1114         * src/nullable.c (set_nullable): Deobfuscate the handling of
1115         ritem.
1116         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1117
1118 2001-12-05  Akim Demaille  <akim@epita.fr>
1119
1120         * src/gram.c, src/gram.h (ritem_print): New.
1121         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1122         (This useless function was defined only to work around VMS linkers
1123         that can't handle compilation units with variables only).
1124         * src/reduce.c (dump_grammar): Use it to trace the construction of
1125         ritem.
1126
1127 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1128
1129         * src/bison.simple (union yyalloc): Change member names
1130         to be the same as the stack names.
1131         (yyparse): yyptr is now union yyalloc *, not char *.
1132         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1133         and may generate better code on some machines.
1134         (yystpcpy): Use prototype if __STDC__ is defined, not just
1135         if __cplusplus is defined.
1136
1137 2001-11-30  Akim Demaille  <akim@epita.fr>
1138
1139         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1140         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1141         Gettext doesn't compile cleanly, and dies with -Werror.
1142         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1143         Include WARNING_CFLAGS here.
1144         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1145         before being defined.
1146
1147 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1148
1149         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1150         First arg is int, not unsigned.
1151         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1152         (SIZE_MAX, UINT_MAX): New macros.
1153         (quotearg_n_options): Abort if N is negative.
1154         Avoid overflow check on hosts where size_t is 64 bits and int
1155         is 32 bits, as overflow is impossible there.
1156         Fix off-by-one typo that caused unnecessary reallocation.
1157
1158 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1159
1160         Name space cleanup in generated parser.
1161
1162         * doc/bison.texinfo (Bison Parser): Discuss system headers
1163         and their effect on the user name space.
1164
1165         * src/bison.simple:
1166         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1167         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1168         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1169
1170         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1171         on user names when possible.
1172
1173         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1174         Simplify test for whather <alloca.h> exists.
1175
1176         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1177
1178         (<stdio.h>): Include if YYDEBUG.
1179
1180         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1181         ! defined (yyoverflow) && ! defined (yymemcpy).
1182
1183         (yymemcpy, yyparse): Rename local variables as needed so that
1184         they all begin with 'yy'.
1185
1186         (yystrlen, yystpcpy): New functions.
1187
1188         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1189         All uses changed.
1190
1191         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1192         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1193         and YYSTACK_FREE instead of malloc and free.
1194
1195 2001-11-30  Akim Demaille  <akim@epita.fr>
1196
1197         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1198         before their first uses.

1204
1205 2001-11-30  Akim Demaille  <akim@epita.fr>
1206
1207         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1208         if body instead of `;' to pacify GCC's warnings.
1209
1210 2001-11-30  Akim Demaille  <akim@epita.fr>
1211
1212         Instead of mapping the LHS of unused rules to -1, keep the LHS
1213         valid, but flag the rules as invalid.
1214
1215         * src/gram.h (rule_t): `useful' is a new member.
1216         * src/print.c (print_grammar): Adjust.

1218         * src/reader.c (packgram, reduce_output): Likewise.
1219         * src/reduce.c (reduce_grammar_tables): Likewise.
1220         * tests/reduce.at (Underivable Rules, Useless Rules): New.
1221

1228
1229 2001-11-30  Akim Demaille  <akim@epita.fr>
1230
1231         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1232         useless nonterminals, move them at the end of the symbol arrays.
1233         (reduce_output): Adjust.
1234         * tests/reduce.at (Useless Nonterminals): Adjust.
1235
1236 2001-11-30  Akim Demaille  <akim@epita.fr>
1237
1238         * src/reduce.c: Various comment/formatting changes.
1239         (nonterminals_reduce): New, extracted from...
1240         (reduce_grammar_tables): here.
1241         (reduce_grammar): Call nonterminals_reduce.
1242
1243 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1244
1245         * src/bison.simple (YYSTACK_REALLOC): Remove.
1246         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1247         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1248         New macros.
1249         (union yyalloc): New type.
1250         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1251         an arbitrary restriction on hosts where size_t is wider than int.
1252
1253         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1254         a parser stack overflow.  Allocate just one block of memory for all
1255         three stacks, instead of allocating three blocks; this typically is
1256         faster and reduces fragmentation.
1257
1258         Do not limit the number of items in the stack to a value that fits
1259         in 'int', as this is an arbitrary limit on hosts with 64-bit
1260         size_t and 32-bit int.
1261
1262 2001-11-29  Marc Autret  <autret_m@epita.fr>
1263

1291         option.

1293 2001-11-28  Marc Autret  <autret_m@epita.fr>
1294

1311
1312         * src/closure.c (closure): `b' and `ruleno' denote the same value:
1313         keep ruleno only.
1314
1315 2001-11-28  Akim Demaille  <akim@epita.fr>
1316
1317         * src/closure.c (closure): Instead of looping over word in array
1318         then bits in words, loop over bits in array.
1319
1320 2001-11-28  Akim Demaille  <akim@epita.fr>
1321
1322         * src/closure.c (closure): No longer optimize the special case
1323         where all the bits of `ruleset[r]' are set to 0, to make the code
1324         clearer.
1325
1326 2001-11-28  Akim Demaille  <akim@epita.fr>
1327
1328         * src/closure.c (closure): `r' and `c' are new variables, used to

1343         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

1348
1349         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
1350         use alloca when we didn't want to, and vice versa.
1351

1454         * src/LR0.c (kernel_size): Contain `int' instead of `size_t' to
1455         pacify GCC's signed < unsigned warnings.

1459 2001-11-23  Akim Demaille  <akim@epita.fr>
1460
1461         Attaching lineno to buckets is stupid, since only one copy of each
1462         symbol is kept, only the line of the first occurrence is kept too.
1463
1464         * src/symtab.h, src/symtab.c (bucket): Remove the line member.
1465         * src/reader.c (rline_allocated): Remove, unused.

2639
2640         * src/bison.simple (yyparse): Don't take the address of an

2650         completely wrong.

2689         bound to true.
2690         (read_declarations): Add case for macro definition.
2691         (copy_identifier): New.
2692         (parse_macro_decl): Read macro identifiers using copy_identifier

2699         (output_parser): Fix bug on '%%line' directives.

2712         table with a macro. No output to the table obstack.
2713         (output_gram): Same for 'rhs' and 'prhs'.

2727         with something new. Skeletons are now processed character by character
2728         rather than line by line, and Bison looks for '%%' macros. This is the
2729         first step in making Bison's output process (a lot) more flexible.
2730         (output_parser): Use the macro table.

3058
3059         * src/reader.c (gensym): `gensym_count' is your own.
3060         Use a static buf to create the symbol name, as token_buffer is no

3064
3065         * src/conflicts.c (conflict_report): Be sure not to append to res

3072         New, from fileutils 4.0.37.
3073         * configure.in: Require Autoconf 2.49c.  I took some time before
3074         making this decision.  This is the only way out for portability
3075         issues in Bison, it would mean way too much duplicate effort to
3076         import in Bison features implemented in 2.49c since 2.13.
3077         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3088
3089         * src/lex.c (token_obstack): New.
3090         (init_lex): Initialize it.  No longer call...

3095
3096         * src/lex.h: Rename all the tokens:

3098         s/\bIDENTIFIER\b/tok_identifier/g;
3099         etc.
3100         Let them be enums, not #define, to ease debugging.
3101         Adjust all the code.
3102
3103 2001-01-18  Akim Demaille  <akim@epita.fr>
3104

3107
3108 2001-01-18  Akim Demaille  <akim@epita.fr>
3109
3110         Since we now use obstacks, more % directives can be enabled.
3111
3112         * src/lex.c (percent_table): Also accept `%yacc',
3113         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3114         `%debug'.
3115         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3116         instead of returning a token.
3117         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3118         * src/reader.c (read_declarations): Adjust.
3119         * src/files.c (open_files): Don't call `compute_base_names', don't
3120         compute `attrsfile' since they depend upon data which might be
3121         *in* the input file now.
3122         (output_files): Do it here.
3123         * src/output.c (output_headers): Document the fact that this patch
3124         introduces a guaranteed SEGV for semantic parsers.

3149         FILE * parameters.
3150
3151 2000-12-20  Akim Demaille  <akim@epita.fr>
3152
3153         * src/files.c (open_files): Actually the `.output' file is based
3154         on the short_base_name, not base_name.
3155         * tests/suite.at (Checking output file names): Adjust.
3156
3157 2000-12-20  Akim Demaille  <akim@epita.fr>
3158
3159         * src/bison.s1: Remove, we now use directly...

3183         (stringappend): Be just like strcat but allocate.
3184         (base_names): Eve out from open_files.
3185         Try to simplify the rather hairy computation of base_name and
3186         short_base_name.
3187         (open_files): Use it.
3188         * tests/suite.at (Checking output file names): New test.

3205
3206 2000-12-19  Akim Demaille  <akim@epita.fr>
3207
3208         Let the handling of the skeleton files be local to the procedures

3254         to escape special characters when outputting filenames.
3255         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.

3258 2000-11-17  Akim Demaille  <akim@epita.fr>
3259
3260         * lib/obstack.h: Formatting changes.
3261         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3262         prevents type checking.
3263         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3264         cast the value to (void *): assigning a `foo *' to a `void *'
3265         variable is valid.
3266         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3267         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3304

3347         * src/main.c (main): Don't use `atexit' to register `done', since
3348         it no longer has to remove tmp files, just call `output_files'
3349         when there are no errors.

3456         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3457
3458         * tests/regression.m4: New file.
3459         Include the core of the sample provided by Piotr Gackiewicz.

3461         properly.

3463 2000-10-04  Akim Demaille  <akim@epita.fr>
3464
3465         * src/reader.c (parse_expect_decl): Keep `count' within the size

3469 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3470
3471         * bison.s1 (yyparse): Assign the default value
3472         unconditionally, to avoid a GCC warning and make the parser a
3473         tad smaller.
3474
3475 2000-10-02  Akim Demaille  <akim@epita.fr>
3476

3484
3485 2000-10-02  Akim Demaille  <akim@epita.fr>
3486
3487         The location tracking mechanism is precious for parse error
3488         messages.  Nevertheless, it is enabled only when `@n' is used in
3489         the grammar, which is a different issue (you can use it in error
3490         message, but not in the grammar per se).  Therefore, there should
3491         be another means to enable it.
3492
3493         * src/getargs.c (getargs): Support `--locations'.
3494         (usage): Report it.
3495         * src/getargs.h (locationsflag): Export it.
3496         * src/lex.c (percent_table): Support `%locations'.
3497         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3498         with `locationsflag'.
3499         * doc/bison.texinfo: Document `--locations' and `%locations'.
3500         Sort the options.
3501         * tests/calc.m4: Test it.
3502
3503         For regularity of the names, replace each
3504         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3505         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3506         In addition replace each `flag' with `_flag'.
3507
3508 2000-10-02  Akim Demaille  <akim@epita.fr>
3509
3510         Also test parse error messages, including with YYERROR_VERBOSE.
3511
3512         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3513         associative).
3514         Use it to check the computations.
3515         Use it to check `nonassoc' is honored.
3516         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3517         `--yyerror-verbose'.
3518         (_AT_CHECK_CALC): Adjust to this option.
3519         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3520
3521 2000-10-02  Akim Demaille  <akim@epita.fr>
3522
3523         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3524         the latter demonstrates a flaw in the handling of non debugging
3525         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3526         was used in order to simplify:
3527
3528         #if YYDEBUG
3529         if (yydebug)
3530         {
3531         ...
3532         }
3533         #endif
3534
3535         into
3536
3537         if (yydebug)
3538         {
3539         ...
3540         }
3541
3542         unfortunately this leads to a CPP conflict when
3543         `--name-prefix=foo' is used since it produces `#define yydebug
3544         foodebug'.
3545
3546         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3547         (YYDPRINTF): New macro.
3548         Spread its use.
3549         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3550         the bison options.
3551         Also test `--verbose', `--defines' and `--name-prefix'.
3552
3553 2000-10-02  Akim Demaille  <akim@epita.fr>
3554
3555         Improve the readability of the produced parsers.
3556
3557         * src/bison.s1: Formatting changes.
3558         Improve the comment related to the `$' mark.
3559         (yydefault): Don't fall through to `yyresume': `goto' there.
3560         * src/output.c (output_parser): When the `$' is met, skip the end
3561         of its line.
3562         New variable, `number_of_dollar_signs', to check there's exactly
3563         one `$' in the parser skeleton.
3564
3565 2000-10-02  Akim Demaille  <akim@epita.fr>
3566
3567         * lib/xstrdup.c: New file, from the fileutils.
3568         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3569         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3570         instead of strlen + xmalloc + strcpy.
3571         * src/symtab.c (copys): Remove, use xstrdup instead.
3572
3573 2000-10-02  Akim Demaille  <akim@epita.fr>
3574
3575         * src/gram.h (associativity): New enum type which replaces the
3576         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3577         `right_assoc', `left_assoc' and `non_assoc'.
3578         Adjust all dependencies.
3579         * src/reader.c: Formatting changes.
3580         (LTYPESTR): Don't define it, use it as a literal in
3581         `reader_output_yylsp'.
3582         * src/symtab.h (symbol_class): New enum type which replaces the
3583         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3584         `sunknown', `stoken and `snterm'.
3585
3586 2000-10-02  Akim Demaille  <akim@epita.fr>
3587
3588         * src/getargs.c (fixed_outfiles): Rename as...
3589         (yaccflag): for consistency and accuracy.
3590         Adjust dependencies.
3591
3592 2000-10-02  Akim Demaille  <akim@epita.fr>
3593
3594         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3595         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3596         difficult and introduced a lot of core dump.  It turns out that
3597         Bison used an implementation of `xmalloc' based on `calloc', and
3598         at various places it does depend upon the initialization to 0.  I
3599         have not tried to isolate the pertinent places, and all the former
3600         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3601         someone should address this issue.

3703
3704         `user_toknums' is output as a `short[]' in `output.c', while it is

3750         * src/system.h: Define PARAMS.
3751         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

3753         definitions in config.h.

3970
3971         Change the handling of @s so that they behave exactly like $s.
3972         There is now a pseudo variable @$ (readble and writable), location
3973         of the lhs of the rule (by default ranging from the location of
3974         the first symbol of the rhs, to the location of the last symbol,
3975         or, if the rhs is empty, YYLLOC).
3976
3977         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3978         yyval.
3979         (yyparse): When providing a default semantic action, provide a
3980         default location action.
3981         (after the $): No longer change `*YYLSP', just stack YYLOC the
3982         same way you stack YYVAL.
3983         * src/reader.c (read_declarations): Use warns.
3984         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3985         (copy_action, case '@'): Likewise.
3986         Use a standard error message, to save useless work from
3987         translators.
3988
3989 2000-03-17  Akim Demaille  <akim@epita.fr>
3990

4009         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4010         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4011         One `#if YYDEBUG' remains, since it uses variables which are
4012         defined only if `YYDEBUG != 0'.
4013

4046         the proper line number and file name.
4047         (DEFS): Propagate the location of bison library files and of the
4048         locale files.
4049         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4050         builddir.
4051         * acinclude.m4: Remove, replaced by the directory m4.
4052         * m4/Makefile.am (EXTRA_DIST): New variable.

4735         buffer while reading an integer.
4736         (parse_percent_token): Replaced if-else statement with percent_table.
4737         (parse_percent_token): Added % declarations as another
4738         way to specify the flags -n, -l, and -r.  Also added hooks for
4739         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4740         major changes to files.c.
4741         (lex) Retain in the incoming stream a character following
4742         an incorrect '/'.
4743         (skip_white_space, lex):  Revised most error messages
4744         and changed fatal to warn to avoid aborting.
4745         (percent_table):  Added %thong declarations.

4751         and actfile file.  Handle noparserflag.  Both for -n switch.
4752
4753         * src/conflicts.c (resolve_sr_conflict):
4754         Remove use of alloca.
