   6
   7 2001-12-29  Akim Demaille  <akim@epita.fr>
   8
   9         Memory leak.
  10
  11         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
  12         since it allocates it for each state, although only one is needed.
  13         (allocate_storage): Do it here.
  14
  15
  16 2001-12-29  Akim Demaille  <akim@epita.fr>
  17
  18         * src/options.h, src/options.c (create_long_option_table): Rename
  19         as...
  20         (long_option_table_new): this, with a clearer prototype.
  21         (percent_table): Remove, unused,
  22         * src/getargs.c (getargs): Adjust.
  23
  24
  25 2001-12-29  Akim Demaille  <akim@epita.fr>

  29         as states.
  30
  31
  32 2001-12-29  Akim Demaille  <akim@epita.fr>
  33
  34         * src/lalr.c (build_relations): Rename `states' as `states1'.
  35         Sorry, I don't understand exactly what it is, no better name...
  36
  37
  38 2001-12-29  Akim Demaille  <akim@epita.fr>
  39
  40         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
  41         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
  42         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
  43         as rules.
  44
  45
  46 2001-12-29  Akim Demaille  <akim@epita.fr>
  47
  48         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
  49         ago.
  50
  51
  52 2001-12-29  Akim Demaille  <akim@epita.fr>
  53
  54         * src/reader.c, src/reader.h (user_toknums): Remove.
  55         Adjust all users to use symbols[i]->user_token_number.
  56
  57
  58 2001-12-29  Akim Demaille  <akim@epita.fr>
  59
  60         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
  61         Adjust all users to use symbols[i]->prec or ->assoc.
  62
  63
  64 2001-12-29  Akim Demaille  <akim@epita.fr>
  65
  66         * src/reader.c, src/reader.h (tags): Remove.
  67         Adjust all users to use symbols[i]->tag.
  68
  69
  70 2001-12-29  Akim Demaille  <akim@epita.fr>
  71
  72         * src/gram.h, src/gram.c (symbols): New, similar to state_table
  73         and rule_table.
  74         * src/reader.c (packsymbols): Fill this table.
  75         Drop sprec.
  76         * src/conflicts.c (resolve_sr_conflict): Adjust.
  77         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
  78         single table.
  79         Use symbols[i]->tag instead of tags[i].
  80
  81
  82 2001-12-29  Akim Demaille  <akim@epita.fr>
  83
  84         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
  85         In addition, put a comment in there, to replace...
  86         * tests/regression.at (%union and C comments): Remove.
  87
  88
  89 2001-12-29  Akim Demaille  <akim@epita.fr>
  90
  91         * tests/regression.at (Web2c Actions): Blindly move the actual
  92         output as expected output.  The contents *seem* right to me, but I
  93         can't pretend reading perfectly parser tables...  Nonetheless, all
  94         the other tests pass correctly, the table look OK, even though the
  95         presence of `$axiom' is to be noted: AFAICS it is useless (but
  96         harmless).
  97
  98
  99 2001-12-29  Akim Demaille  <akim@epita.fr>
 100
 101         * src/reader.c (readgram): Don't add the rule 0 if there were no
 102         rules read.  In other words, add it _after_ having performed
 103         grammar sanity checks.
 104         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 105
 106
 107 2001-12-29  Akim Demaille  <akim@epita.fr>
 108
 109         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 110         visible, and some states have now a different number.
 111
 112
 113 2001-12-29  Akim Demaille  <akim@epita.fr>
 114
 115         * src/reader.c (readgram): Bind the initial rule's lineno to that
 116         of the first rule.
 117         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 118         (Solved SR Conflicts): Adjust rule 0's line number.
 119
 120
 121 2001-12-29  Akim Demaille  <akim@epita.fr>
 122
 123         Fix the `GAWK Grammar' failure.
 124
 125         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 126         the reductions of the first state which was mistakenly confused
 127         with the final state because precisely final_state was initialized
 128         to 0.
 129         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 130         now noticed by Bison.
 131         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 132         have a reduction on $default.
 133
 134
 135 2001-12-29  Akim Demaille  <akim@epita.fr>
 136
 137         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 138         rule line numbers.
 139         * src/closure.c (print_closure): Likewise.
 140         * src/derives.c (print_derives): Likewise.
 141         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 142         now.
 143
 144 2001-12-29  Akim Demaille  <akim@epita.fr>
 145
 146         * src/lalr.c (lookaheads_print): New.
 147         (lalr): Call it when --trace-flag.
 148         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 149         are dumped.
 150
 151
 152 2001-12-29  Akim Demaille  <akim@epita.fr>
 153
 154         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 155         when walking through ritem, even via rule->rhs.
 156         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 157         (useful_production, useless_nonterminals): Likewise.
 158         (reduce_grammar_tables): Likewise, plus update nritems.
 159         * src/nullable.c (set_nullable): Likewise.
 160         * src/lalr.c (build_relations): Likewise.
 161         * tests/sets.at (Nullable): Adjust.
 162         Fortunately, now, the $axiom is no longer nullable.
 163
 164
 165 2001-12-29  Akim Demaille  <akim@epita.fr>
 166
 167         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 168         the 0-sentinel.
 169         * src/gram.c (ritem_longest_rhs): Likewise.
 170         * src/reduce.c (nonterminals_reduce): Likewise.
 171         * src/print_graph.c (print_graph): Likewise.
 172         * src/output.c (output_rule_data): Likewise.
 173         * src/nullable.c (set_nullable):  Likewise.
 174
 175 2001-12-29  Akim Demaille  <akim@epita.fr>
 176
 177         * src/output.c: Comment changes.
 178
 179 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 180
 181         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 182         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 183         Sparc, as they were causing more porting problems than the
 184         (minor) performance improvement was worth.
 185
 186         Also, catch up with 1.31's YYSTD.
 187
 188 2001-12-27  Akim Demaille  <akim@epita.fr>
 189
 190         * src/output.c (output_gram): Rely on nritems, not the
 191         0-sentinel.  See below.
 192         Use -1 as separator, not 0.
 193         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 194         Rely on -1 as separator in yyrhs, instead of 0.
 195         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 196         twice `Now at end of input', therefore there are two lines less to
 197         expect.
 198
 199 2001-12-27  Akim Demaille  <akim@epita.fr>
 200
 201         * tests/regression.at (Unresolved SR Conflicts):
 202         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 203         below.
 204
 205 2001-12-27  Akim Demaille  <akim@epita.fr>
 206
 207         * src/LR0.c (new_state): Recognize the final state by the fact it
 208         is reached by eoftoken.
 209         (insert_start_shifting_state, insert_eof_shifting_state)
 210         (insert_accepting_state, augment_automaton): Remove, since now
 211         these states are automatically computed from the initial state.
 212         (generate_states): Adjust.
 213         * src/print.c: When reporting a rule number to the user, substract
 214         1, so that the axiom rule is rule 0, and the first user rule is 1.
 215         * src/reduce.c: Likewise.
 216         * src/print_graph.c (print_core): For the time being, just as for
 217         the report, depend upon --trace-flags to dump the full set of
 218         items.
 219         * src/reader.c (readgram): Once the grammar read, insert the rule
 220         0: `$axiom: START-SYMBOL $'.
 221         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 222         number of the states has changed (the final state is no longer
 223         necessarily the last), catch up.
 224
 225 2001-12-27  Akim Demaille  <akim@epita.fr>
 226
 227         Try to make the use of the eoftoken valid.  Given that its value
 228         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 229         is used instead of > 0 where appropriate, (ii), depend upon nritems
 230         instead of the 0-sentinel.
 231
 232         * src/gram.h, src/gram.c (nritems): New.
 233         Expected to be duplication of nitems, but for the time being...
 234         * src/reader.c (packgram): Assert nritems and nitems are equal.
 235         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 236         * src/closure.c (print_closure, print_fderives): Likewise.
 237         * src/gram.c (ritem_print): Likewise.
 238         * src/print.c (print_core, print_grammar): Likewise.
 239         * src/print_graph.c: Likewise.
 240
 241 2001-12-27  Akim Demaille  <akim@epita.fr>
 242
 243         * src/main.c (main): If there are complains after grammar
 244         reductions, then output the report anyway if requested, then die.
 245         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 246         * src/reader.c (eoftoken): New.
 247         (parse_token_decl): If the token being defined has value `0', it
 248         is the eoftoken.
 249         (packsymbols): No longer hack `tags' to insert `$' by hand.
 250         Be sure to preserve the value of the eoftoken.
 251         (reader): Make sure eoftoken is defined.
 252         Initialize nsyms to 0: now eoftoken is created just like the others.
 253         * src/print.c (print_grammar): Don't special case the eof token.
 254         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 255         lie anyway, albeit pleasant.
 256         * tests/calc.at: Exercise error messages with eoftoken.
 257         Change the grammar so that empty input is invalid.
 258         Adjust expectations.
 259         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 260
 261 2001-12-27  Akim Demaille  <akim@epita.fr>
 262
 263         * configure.in: Check the protos of strchr ans strspn.
 264         Replace strchr if needed.
 265         * src/system.h: Provide the protos of strchr, strspn and memchr if
 266         missing.
 267         * lib/strchr.c: New.
 268         * src/reader.c (symbols_save): Use strchr.
 269
 270 2001-12-27  Akim Demaille  <akim@epita.fr>
 271
 272         * src/print.c, src/print_graph.c (escape): New.
 273         Use it to quote the TAGS outputs.
 274         * src/print_graph.c (print_state): Now errors are in red, and
 275         reductions in green.
 276         Prefer high to wide: output the state number on a line of its own.
 277
 278 2001-12-27  Akim Demaille  <akim@epita.fr>
 279
 280         * src/state.h, src/state.c (reductions_new): New.
 281         * src/LR0.c (set_state_table): Let all the states have a
 282         `reductions', even if reduced to 0.
 283         (save_reductions): Adjust.
 284         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 285         * src/print.c (print_reductions, print_actions): Adjust.
 286         * src/output.c (action_row): Adjust.
 287
 288 2001-12-27  Akim Demaille  <akim@epita.fr>
 289
 290         * src/state.h, src/state.c (errs_new, errs_dup): New.
 291         * src/LR0.c (set_state_table): Let all the states have an errs,
 292         even if reduced to 0.
 293         * src/print.c (print_errs, print_reductions): Adjust.
 294         * src/output.c (output_actions, action_row): Adjust.
 295         * src/conflicts.c (resolve_sr_conflict): Adjust.
 296
 297 2001-12-27  Akim Demaille  <akim@epita.fr>
 298
 299         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 300
 301 2001-12-27  Akim Demaille  <akim@epita.fr>
 302
 303         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 304         * src/print.c: here.
 305         (lookaheadset, shiftset): New, used as additional storage by
 306         print_reductions.
 307         (print_results): Adjust.
 308         (print_shifts, print_gotos, print_errs): New, extracted from...
 309         (print_actions): here.
 310         * src/print_graph.c (print_actions): Remove dead code.
 311
 312 2001-12-27  Akim Demaille  <akim@epita.fr>
 313
 314         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 315         `$n' and `@n'.
 316
 317 2001-12-27  Akim Demaille  <akim@epita.fr>
 318
 319         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 320         (build_relations): Adjust.
 321
 322 2001-12-27  Akim Demaille  <akim@epita.fr>
 323
 324         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 325         duplication.
 326
 327 2001-12-27  Akim Demaille  <akim@epita.fr>
 328
 329         * src/reader.c (packgram): Catch nitems overflows.
 330
 331 2001-12-27  Akim Demaille  <akim@epita.fr>
 332
 333         * src/files.c, src/files.h (guard_obstack): Remove.
 334         * src/output.c (output): Adjust.
 335         * src/reader.c (parse_braces): New, factoring...
 336         (copy_action, copy_guard): these two which are renamed as...
 337         (parse_action, parse_guard): these.
 338         As a voluntary consequence, using braces around guards is now
 339         mandatory.
 340
 341 2001-12-27  Akim Demaille  <akim@epita.fr>
 342
 343         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 344         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 345         members.
 346         (symbol_list_new): Adjust.
 347         (copy_action): action_line is the first line, not the last.
 348         (copy_guard): Just as for actions, store the `action' only, not
 349         the switch/case/break flesh.
 350         Don't parse the user action that might follow the guard, let...
 351         (readgram): do it, i.e., now, there can be an action after a
 352         guard.
 353         In other words the guard is just explicitly optional.
 354         (packgram): Adjust.
 355         * src/output.c (guards_output): New.
 356         (output_parser): Call it when needed.
 357         (output): Also free the guard and attrs obstacks.
 358         * src/files.c, src/files.h (obstack_save): Remove.
 359         (output_files): Remove.
 360         As a result, if one needs the former `.act' file, using an
 361         appropriate skeleton which requires actions and guards is now
 362         required.
 363         * src/main.c (main): Adjust.
 364         * tests/semantic.at: New.
 365         * tests/regression.at: Use `input.y' as input file name.
 366         Avoid 8+3 problems by requiring input.c when the test needs the
 367         parser.
 368
 369 2001-12-27  Akim Demaille  <akim@epita.fr>
 370
 371         * src/reader.c (symbol_list_new): Be sure to initialize all the
 372         fields.
 373
 374 2001-12-27  Akim Demaille  <akim@epita.fr>
 375
 376         All the hacks using a final pseudo state are now useless.
 377
 378         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 379         * src/lalr.c (nLA): New.
 380         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 381         instead of lookaheadsp from the pseudo state (nstate + 1).
 382
 383 2001-12-27  Akim Demaille  <akim@epita.fr>
 384
 385         * src/output.c (action_row, token_actions): Use a state_t instead
 386         of a integer, and nlookaheads instead of the following state's
 387         lookaheadsp.
 388
 389 2001-12-27  Akim Demaille  <akim@epita.fr>
 390
 391         * src/conflicts.c (log_resolution, flush_shift)
 392         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 393         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 394         (conflicts_print, print_reductions): Use a state_t instead of an
 395         integer when referring to a state.
 396         As much as possible, depend upon nlookaheads, instead of the
 397         `lookaheadsp' member of the following state (since lookaheads of
 398         successive states are successive, the difference between state n + 1
 399         and n served as the number of lookaheads for state n).
 400         * src/lalr.c (add_lookback_edge): Likewise.
 401         * src/print.c (print_core, print_actions, print_state)
 402         (print_results): Likewise.
 403         * src/print_graph.c (print_core, print_actions, print_state)
 404         (print_graph): Likewise.
 405         * src/conflicts.h: Adjust.
 406
 407 2001-12-27  Akim Demaille  <akim@epita.fr>
 408
 409         * src/bison.hairy: Formatting/comment changes.
 410         ANSIfy.
 411         Remove `register' indications.
 412         Add plenty of `static'.
 413
 414 2001-12-27  Akim Demaille  <akim@epita.fr>
 415
 416         * src/output.c (prepare): Drop the muscle `ntbase' which
 417         duplicates ntokens.
 418         * src/bison.simple: Formatting/comment changes.
 419         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 420         is an undocumented synonym.
 421
 422 2001-12-22  Akim Demaille  <akim@epita.fr>
 423
 424         * src/output.c (output_table_data): Change the prototype to use
 425         `int' for array ranges: some invocations do pass an int, not a
 426         short.
 427         Reported by Wayne Green.
 428
 429 2001-12-22  Akim Demaille  <akim@epita.fr>
 430
 431         Some actions of web2c.y are improperly triggered.
 432         Reported by Mike Castle.
 433
 434         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 435         * tests/regression.at (Web2c): Rename as...
 436         (Web2c Report): this.
 437         (Web2c Actions): New.
 438
 439 2001-12-22  Akim Demaille  <akim@epita.fr>
 440
 441         Reductions in web2c.y are improperly reported.
 442         Reported by Mike Castle.
 443
 444         * src/conflicts.c (print_reductions): Fix.
 445         * tests/regression.at (Web2c): New.
 446
 447 2001-12-18  Akim Demaille  <akim@epita.fr>
 448
 449         Some host fail on `assert (!"foo")', which expands to
 450         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 451         Reported by Nelson Beebee.
 452
 453         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 454         `#define it_succeeded 0' and `assert (it_succeeded)'.
 455
 456 2001-12-17  Marc Autret  <autret_m@epita.fr>
 457
 458         * src/bison.simple: Don't hard code the skeleton line and filename.
 459         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 460         New line counter 'skeleton_line' (skeleton-line muscle).
 461
 462 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 463
 464         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 465         YYDEBUG must be defined to a nonzero value.
 466
 467         * src/bison.simple (yytname): Do not assume that the user defines
 468         YYDEBUG to a properly parenthesized expression.
 469
 470 2001-12-17  Akim Demaille  <akim@epita.fr>
 471
 472         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 473         nlookaheads is a new member.
 474         Adjust all users.
 475         * src/lalr.h (nlookaheads): Remove this orphan declaration.
 476         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 477         state.
 478
 479 2001-12-17  Akim Demaille  <akim@epita.fr>
 480
 481         * src/files.h, src/files.c (open_files, close_files): Remove.
 482         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 483         let...
 484         * src/reader.c (reader): Do it.
 485
 486 2001-12-17  Akim Demaille  <akim@epita.fr>
 487
 488         * src/conflicts.c (print_reductions): Formatting changes.
 489
 490 2001-12-17  Akim Demaille  <akim@epita.fr>
 491
 492         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 493         (flush_reduce): New.
 494         (resolve_sr_conflict): Adjust.
 495
 496 2001-12-17  Akim Demaille  <akim@epita.fr>
 497
 498         * src/output.c (output_obstack): Be static and rename as...
 499         (format_obstack): this, to avoid any confusion with files.c's
 500         output_obstack.
 501         * src/reader.h (muscle_obstack): Move to...
 502         * src/output.h: here, since it's defined in output.c.
 503
 504 2001-12-17  Akim Demaille  <akim@epita.fr>
 505
 506         * src/output.c (action_row, save_column, default_goto)
 507         (sort_actions, matching_state, pack_vector): Better variable
 508         locality.
 509
 510 2001-12-17  Akim Demaille  <akim@epita.fr>
 511
 512         * src/output.c: Various formatting changes.
 513
 514 2001-12-17  Akim Demaille  <akim@epita.fr>
 515
 516         * src/files.c (output_files): Free the output_obstack.
 517         * src/main.c (main): Call print and print_graph conditionally.
 518         * src/print.c (print): Work unconditionally.
 519         * src/print_graph.c (print_graph): Work unconditionally.
 520         * src/conflicts.c (log_resolution): Output only if verbose_flag.
 521
 522 2001-12-16  Marc Autret  <autret_m@epita.fr>
 523
 524         * src/output.c (actions_output): Fix. When we use %no-lines,
 525         there is one less line per action.
 526
 527 2001-12-16  Marc Autret  <autret_m@epita.fr>
 528
 529         * src/bison.simple: Remove a useless #line directive.
 530         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 531         * src/output.c (get_lines_number): New.
 532         (output_parser): Adjust, now takes care about the lines of a
 533         output muscles.
 534         Fix line numbering.
 535         (actions_output): Computes the number of lines taken by actions.
 536         (output_master_parser): Insert new skeleton which is the name of
 537         the output parser file name.
 538
 539 2001-12-15  Marc Autret  <autret_m@epita.fr>
 540
 541         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
 542
 543 2001-12-15  Marc Autret  <autret_m@epita.fr>
 544
 545         * src/output.c (output_gram): Keep track of the hairy one.
 546
 547 2001-12-15  Akim Demaille  <akim@epita.fr>
 548
 549         Make `make distcheck' work.
 550
 551         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 552         system.h which uses libgettext.h.
 553
 554 2001-12-15  Akim Demaille  <akim@epita.fr>
 555
 556         * src/nullable.c (set_nullable): Useless rules must be skipped,
 557         otherwise, since we range over their symbols, we might look at a
 558         nonterminal which no longer ``exists'', i.e., it is not counted in
 559         `nvars', hence we overflow our arrays.
 560
 561 2001-12-15  Akim Demaille  <akim@epita.fr>
 562
 563         The header can also be produced directly, without any obstack!
 564         Yahoo!
 565
 566         * src/files.c, src/files.h (defines_obstack): Remove.
 567         (compute_header_macro): Global.
 568         (defines_obstack_save): Remove.
 569         * src/reader.c (parse_union_decl): No longer output to
 570         defines_obstack: its content can be found in the `stype' muscle
 571         anyway.
 572         (output_token_translations): Merge into...
 573         (symbols_output): this.
 574         Rename as...
 575         (symbols_save): this.
 576         (reader): Adjust.
 577         * src/output.c (header_output): New.
 578         (output): Call it.
 579
 580 2001-12-15  Akim Demaille  <akim@epita.fr>
 581
 582         * src/reader.c (parse_union_decl): Instead of handling two obstack
 583         simultaneously, use one to define the `stype' muscle, and use the
 584         value of the latter to fill defines_obstack.
 585         (copy_comment): Remove.
 586         (copy_comment2): Work for a single obstack.
 587         Rename as...
 588         (copy_comment): this.
 589
 590 2001-12-15  Akim Demaille  <akim@epita.fr>
 591
 592         * src/lex.c, src/lex.h (xgetc): No longer static.
 593         * src/reader.c (parse_union_decl): Revamp.
 594
 595 2001-12-15  Akim Demaille  <akim@epita.fr>
 596
 597         Still making progress in separating Bison into (i) input, (ii)
 598         process, (iii) output: now we can directly output the parser file
 599         without using table_obstack at all.
 600
 601         * src/files.c, src/files.h (table_obstack): Bye bye.
 602         (parser_file_name): New.
 603         * src/files.c (compute_output_file_names): Compute it.
 604         * src/output.c (actions_output, output_parser)
 605         (output_master_parser): To a file instead of an obstack.
 606
 607 2001-12-15  Akim Demaille  <akim@epita.fr>
 608
 609         Attach actions to rules, instead of pre-outputting them to
 610         actions_obstack.
 611
 612         * src/gram.h (rule_t): action and action_line are new members.
 613         * src/reader.c (symbol_list): Likewise.
 614         (copy_action): Save the actions within the rule.
 615         (packgram): Save them in rule_table.
 616         * src/output.c (actions_output): New.
 617         (output_parser): Use it on `%%actions'.
 618         (output_rule_data): Don't free rule_table.
 619         (output): Do it.
 620         (prepare): Don't save the `action' muscle.
 621         * src/bison.simple: s/%%action/%%actions/.
 622
 623 2001-12-15  Akim Demaille  <akim@epita.fr>
 624
 625         * src/reader.c (copy_action): When --yacc, don't append a `;'
 626         to the user action: let it fail if lacking.
 627         Suggested by Arnold Robbins and Tom Tromey.
 628
 629 2001-12-14  Akim Demaille  <akim@epita.fr>
 630
 631         * src/lex.c (literalchar): Simply return the char you decoded, non
 632         longer mess around with obstacks and int pointers.
 633         Adjust all callers.
 634
 635 2001-12-14  Akim Demaille  <akim@epita.fr>
 636
 637         * src/lex.c (literalchar): Don't escape the special characters,
 638         just decode them, and keep them as char (before, eol was output as
 639         the 2 char string `\n' etc.).
 640         * src/output.c (output_rule_data): Use quotearg to output the
 641         token strings.
 642
 643 2001-12-13  Paul Eggert  <eggert@twinsun.com>
 644
 645         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
 646         Do not infringe on the global user namespace when using C++.
 647         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
 648         All uses of `fprintf' and `stderr' changed.
 649
 650         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
 651
 652 2001-12-13  Akim Demaille  <akim@epita.fr>
 653
 654         The computation of nullable is broken: it doesn't handle empty
 655         RHS's properly.
 656
 657         * tests/torture.at (GNU AWK Grammar): New.
 658         * tests/sets.at (Nullable): New.
 659         * src/nullable.c (set_nullable): Instead of blindly looping over
 660         `ritems', loop over the rules, and then over their rhs's.
 661
 662         Work around Autotest bugs.
 663
 664         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
 665         frame, because Autotest understand lines starting with a `+' as
 666         traces from the shell.  Then, they are not processed properly.
 667         Admittedly an Autotest bug, but we don't have time to wait for
 668         Autotest to catch up.
 669         * tests/regression.at (Broken Closure): Adjust to the new table
 670         frames.
 671         Move to...
 672         * tests/sets.at: here.
 673
 674 2001-12-13  Akim Demaille  <akim@epita.fr>
 675
 676         * src/closure.c (closure): Use nrules instead of playing tricks
 677         with BITS_PER_WORD.
 678
 679 2001-12-13  Akim Demaille  <akim@epita.fr>
 680
 681         * src/print.c (print_actions): Output the handling of `$' as the
 682         traces do: shifting the token EOF.  Before EOF was treated as a
 683         nonterminal.
 684         * tests/regression.at: Adjust some tests.
 685         * src/print_graph.c (print_core): Complete the set of items via
 686         closure.  The next-to-final and final states are still unsatisfying,
 687         but that's to be addressed elsewhere.
 688         No longer output the rule numbers, but do output the state number.
 689         A single loop for the shifts + gotos is enough, but picked a
 690         distinct color for each.
 691         (print_graph): Initialize and finalize closure.
 692
 693 2001-12-13  Akim Demaille  <akim@epita.fr>
 694
 695         * src/reader.c (readgram): Remove dead code, an strip useless
 696         braces.
 697         (get_type): Remove, unused.
 698
 699 2001-12-12  Akim Demaille  <akim@epita.fr>
 700
 701         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 702         on that of lib/error.c.
 703
 704 2001-12-12  Akim Demaille  <akim@epita.fr>
 705
 706         Some hosts don't like `/' in includes.
 707
 708         * src/system.h: Include libgettext.h without qualifying the path.
 709         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 710         $(top_srcdir).
 711
 712 2001-12-11  Marc Autret  <autret_m@epita.fr>
 713
 714         * src/output.c (output_parser): Remove useless muscle.
 715
 716 2001-12-11  Marc Autret  <autret_m@epita.fr>
 717
 718         * src/bison.simple: Remove #line just before %%epilogue. It
 719         is now handled in ...
 720         * src/reader.c (read_additionnal_code): Add the output of a
 721         #line for the epilogue.
 722
 723 2001-12-10  Marc Autret  <autret_m@epita.fr>
 724
 725         * src/reader.c (copy_definition): Re-use CPP-outed code which
 726         replace precedent remove.
 727         * src/bison.simple: Remove #line before %%prologue because
 728         %%input-line is wrong at this time.
 729
 730 2001-12-10  Marc Autret  <autret_m@epita.fr>
 731
 732         * src/reader.c (symbols_output): Clean up.
 733         * src/output.c (output_gram, output): Clean up.
 734
 735 2001-12-10  Akim Demaille  <akim@epita.fr>
 736
 737         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 738         * src/LR0.c (set_state_table): here.
 739         * src/lalr.c (lalr): Call it.
 740
 741 2001-12-10  Akim Demaille  <akim@epita.fr>
 742
 743         * src/state.h (shifts): Remove the `number' member: shifts are
 744         attached to state, hence no longer need to be labelled with a
 745         state number.
 746
 747 2001-12-10  Akim Demaille  <akim@epita.fr>
 748
 749         Now that states have a complete set of members, the linked list of
 750         shifts is useless: just fill directly the state's shifts member.
 751
 752         * src/state.h (shifts): Remove the `next' member.
 753         * src/LR0.c (first_state, last_state): Remove.
 754         Adjust the callers.
 755         (augment_automaton): Don't look for the shifts that must be added
 756         a shift on EOF: it is those of the state we looked for!  But now,
 757         since shifts are attached, it is no longer needed to looking
 758         merely by its id: its number.
 759
 760 2001-12-10  Akim Demaille  <akim@epita.fr>
 761
 762         * src/LR0.c (augment_automaton): Better variable locality.
 763         Remove an impossible branch: if there is a state corresponding to
 764         the start symbol being shifted, then there is shift for the start
 765         symbol from the initial state.
 766
 767 2001-12-10  Akim Demaille  <akim@epita.fr>
 768
 769         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 770         only when appropriate: when insert_start_shifting_state' is not
 771         invoked.
 772         * tests/regression.at (Rule Line Numbers): Adjust.
 773
 774 2001-12-10  Akim Demaille  <akim@epita.fr>
 775
 776         * src/LR0.c (augment_automaton): Now that all states have shifts,
 777         merge the two cases addition shifts to the initial state.
 778
 779 2001-12-10  Akim Demaille  <akim@epita.fr>
 780
 781         * src/lalr.c (set_state_table): Move to...
 782         * src/LR0.c: here.
 783         * src/lalr.c (lalr): Don't call it...
 784         * src/LR0.c (generate_states): do it.
 785         * src/LR0.h (first_state): Remove, only the table is used.
 786
 787 2001-12-10  Akim Demaille  <akim@epita.fr>
 788
 789         * src/LR0.h (first_shift, first_reduction): Remove.
 790         * src/lalr.c: Don't use first_shift: find shifts through the
 791         states.
 792
 793 2001-12-10  Akim Demaille  <akim@epita.fr>
 794
 795         * src/LR0.c: Attach shifts to states as soon as they are
 796         computed.
 797         * src/lalr.c (set_state_table): Instead of assigning shifts to
 798         state, just assert that the mapping was properly done.
 799
 800 2001-12-10  Akim Demaille  <akim@epita.fr>
 801
 802         * src/LR0.c (insert_start_shift): Rename as...
 803         (insert_start_shifting_state): this.
 804         (insert_eof_shifting_state, insert_accepting_state): New.
 805         (augment_automaton): Adjust.
 806         Better locality of the variables.
 807         When looking if the start_symbol is shifted from the initial
 808         state, using `while (... symbol != start_symbol ...)' sounds
 809         better than `while (... symbol < start_symbol ...)': If fail
 810         to see how the order between symbols could be relevant!
 811
 812 2001-12-10  Akim Demaille  <akim@epita.fr>
 813
 814         * src/getargs.h: Don't declare `spec_name_prefix' and
 815         `spec_file_prefix', declared by src/files.h.
 816         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 817         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 818         * src/output.c (prepare): Adjust.
 819         * src/reader.c (symbols_output): Likewise.
 820         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 821
 822 2001-12-10  Akim Demaille  <akim@epita.fr>
 823
 824         * src/muscle_tab.c (muscle_init): NULL is a better default than
 825         `"0"'.
 826
 827 2001-12-10  Akim Demaille  <akim@epita.fr>
 828
 829         * src/reader.c (reader): Calling symbols_output once is enough.
 830
 831 2001-12-10  Akim Demaille  <akim@epita.fr>
 832
 833         Now that states have a complete set of members, the linked list of
 834         reductions is useless: just fill directly the state's reductions
 835         member.
 836
 837         * src/state.h (struct reductions): Remove member `number' and
 838         `next'.
 839         * src/LR0.c (first_reduction, last_reduction): Remove.
 840         (save_reductions): Don't link the new reductions, store them in
 841         this_state.
 842         * src/lalr.c (set_state_table): No need to attach reductions to
 843         states, it's already done.
 844         * src/output.c (output_actions): No longer free the shifts, then
 845         the reductions, then the states: free all the states and their
 846         members.
 847
 848 2001-12-10  Akim Demaille  <akim@epita.fr>
 849
 850         * src/options.c (OPTN, DRTV, BOTH): New.
 851         (option_table): Use them.
 852
 853         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 854         the job of system.h.
 855         * src/options.c: Don't include stdio.h and xalloc.h for the same
 856         reasons.
 857
 858 2001-12-10  Akim Demaille  <akim@epita.fr>
 859
 860         * src/output.c (output, prepare): Make sure the values of the
 861         muscles `action' and `prologue' are 0-terminated.
 862
 863 2001-12-10  Akim Demaille  <akim@epita.fr>
 864
 865         Clean up GCC warnings.
 866
 867         * src/reader.c (copy_action): `buf' is not used.
 868         (parse_skel_decl): Be static.
 869         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 870         * src/options.h (create_long_option_table): Have a real prototype.
 871         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 872         (hash_delete_at): Return const void *.
 873         Adjust casts to preserve the const.
 874
 875 2001-12-10  Akim Demaille  <akim@epita.fr>
 876
 877         * configure.in: Require 2.52g.
 878         M4 is not needed, but AUTOM4TE is.
 879         * m4/m4.m4: Remove.
 880         * tests/Makefile.am: Adjust.
 881
 882 2001-12-10  Akim Demaille  <akim@epita.fr>
 883
 884         One structure for states is enough, even though theoretically
 885         there are LR(0) states and LALR(1) states.
 886
 887         * src/lalr.h (state_t): Remove.
 888         (state_table): Be state_t **, not state_t *.
 889         * src/state.h (core, CORE_ALLOC): Rename as...
 890         (state_t, STATE_ALLOC): this.
 891         Add the LALR(1) members: shifts, reductions, errs.
 892         * src/LR0.c (state_table): Rename as...
 893         (state_hash): this, to avoid name clashes with the global
 894         `state_table'.
 895         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 896         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 897
 898 2001-12-10  Akim Demaille  <akim@epita.fr>
 899
 900         Bison dumps core on bash.y.
 901         Reported by Pascal Bart.
 902
 903         * src/warshall.c (bitmatrix_print): New.
 904         (TC): Use it.
 905         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 906         j must be the outer loop.
 907         * tests/regression.at (Broken Closure): New.
 908
 909 2001-12-05  Akim Demaille  <akim@epita.fr>
 910
 911         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 912         its argument.
 913         Reported by Peter Hámorský.
 914
 915 2001-12-05  Akim Demaille  <akim@epita.fr>
 916
 917         * src/conflicts.c (err_table): Remove.
 918         (resolve_sr_conflict): Adjust.
 919         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 920         Rename as...
 921         (state_t.reductions, state_t.shifts): this.
 922
 923 2001-12-05  Akim Demaille  <akim@epita.fr>
 924
 925         * src/reduce.c (reduce_grammar_tables): No longer disable the
 926         removal of useless rules via CPP but via `if (0)', so that the
 927         compiler still check the code is valid.
 928         For instance, it should have noticed `rline' no longer exists: use
 929         the `line' member of rule_t.
 930         * src/gram.c (dummy, rline): Remove, unused.
 931
 932 2001-12-05  Akim Demaille  <akim@epita.fr>
 933
 934         * src/output.c (pack_vector): Use assert, not berror.
 935         * src/main.c (berror): Remove, unused.
 936
 937 2001-12-05  Akim Demaille  <akim@epita.fr>
 938
 939         New experimental feature: if --verbose --trace output all the
 940         items of a state, not only its kernel.
 941
 942         * src/print.c (print_core): If `trace_flag', then invoke closure
 943         before outputting the items of the state (print_core is no longer
 944         a correct name them).
 945         (print_results): Invoke new_closure/free_closure if needed.
 946
 947 2001-12-05  Akim Demaille  <akim@epita.fr>
 948
 949         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 950         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 951         (nitemset): for consistency with the rest of the project.
 952
 953 2001-12-05  Akim Demaille  <akim@epita.fr>
 954
 955         * src/closure.c (print_closure): Improve.
 956         (closure): Use it for printing input and output.
 957
 958 2001-12-05  Akim Demaille  <akim@epita.fr>
 959
 960         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 961         indexed by nonterminals.
 962
 963 2001-12-05  Akim Demaille  <akim@epita.fr>
 964
 965         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 966         what it was!).
 967         * src/warshall.h: Remove accidental duplication of the content.
 968
 969 2001-12-05  Akim Demaille  <akim@epita.fr>
 970
 971         * src/closure.c (set_fderives): De-obfuscate.

 973 2001-12-05  Akim Demaille  <akim@epita.fr>
 974
 975         * src/closure.c (print_firsts, print_fderives): De-obfuscate.

 977 2001-12-05  Akim Demaille  <akim@epita.fr>
 978
 979         * src/closure.c (set_firsts): De-obfuscate.
 980
 981 2001-12-05  Akim Demaille  <akim@epita.fr>
 982
 983         * src/output.c (action_row): De-obfuscate
 984         using the good o' techniques: arrays not pointers, variable
 985         locality, BITISSET, RESETBIT etc.
 986
 987 2001-12-05  Akim Demaille  <akim@epita.fr>
 988
 989         Pessimize the code to simplify it: from now on, all the states
 990         have a valid SHIFTS, which NSHIFTS is possibly 0.
 991
 992         * src/LR0.c (shifts_new): Be global and move to..
 993         * src/state.c, src/state.h: here.
 994         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 995         * src/print_graph: Adjust.
 996
 997 2001-12-05  Akim Demaille  <akim@epita.fr>
 998
 999         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1000         * src/conflicts.c: Use it.
1001         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1002         incorrectly ``simplified''.
1003
1004 2001-12-05  Akim Demaille  <akim@epita.fr>
1005
1006         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1007         using the good o' techniques: arrays not pointers, variable
1008         locality, BITISSET, RESETBIT etc.
1009
1010 2001-12-05  Akim Demaille  <akim@epita.fr>
1011
1012         * src/state.h (SHIFT_SYMBOL): New.
1013         * src/conflicts.c: Use it to deobfuscate.
1014
1015 2001-12-05  Akim Demaille  <akim@epita.fr>
1016
1017         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1018         (print_reductions): De-obfuscate using the good o' techniques:
1019         arrays not pointers, variable locality, BITISSET.
1020
1021 2001-12-05  Akim Demaille  <akim@epita.fr>
1022
1023         * src/conflicts.c (print_reductions): Arrays, not pointers.
1024         Use BITISSET.
1025
1026 2001-12-05  Akim Demaille  <akim@epita.fr>
1027
1028         * src/conflicts.c (print_reductions): Pessimize, but clarify.

1031

1043
1044         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

1046
1047 2001-12-05  Akim Demaille  <akim@epita.fr>
1048
1049         * src/LR0.c (augment_automaton): Formatting changes.
1050         Better variable locality.
1051
1052 2001-12-05  Akim Demaille  <akim@epita.fr>
1053
1054         * src/lalr.c (matrix_print): New.
1055         (transpose): Use it.
1056         Use arrays instead of pointers.
1057
1058 2001-12-05  Akim Demaille  <akim@epita.fr>
1059
1060         * src/lalr.c (maxrhs): Move to...
1061         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1062         * src/lalr.c (build_relations): Adjust.
1063
1064 2001-12-05  Akim Demaille  <akim@epita.fr>
1065
1066         * src/lalr.c (transpose): Free the memory allocated to the
1067         argument, as it is replaced by the results by the unique caller.
1068         (build_relations): Merely invoke transpose: it handles the memory
1069         deallocation.
1070         Improve variable locality.
1071         Avoid variables used as mere abbreviations.
1072         (compute_lookaheads): Use arrays instead of pointers.
1073
1074 2001-12-05  Akim Demaille  <akim@epita.fr>
1075
1076         * src/lalr.c (initialize_F): Improve variable locality.
1077         Avoid variables used as mere abbreviations.
1078
1079 2001-12-05  Akim Demaille  <akim@epita.fr>
1080
1081         * src/derives.c (print_derives): Display the ruleno.
1082         * src/lalr.c (initialize_F, transpose): Better variable locality
1083         to improve readability.
1084         Avoid variables used as mere abbreviations.
1085
1086 2001-12-05  Akim Demaille  <akim@epita.fr>
1087
1088         * src/lalr.c (traverse): Use arrays instead of pointers.
1089
1090 2001-12-05  Akim Demaille  <akim@epita.fr>
1091
1092         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1093         the handling of squeue.
1094         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1095
1096 2001-12-05  Akim Demaille  <akim@epita.fr>
1097
1098         Because useless nonterminals are now kept alive (instead of being
1099         `destroyed'), we now sometimes examine them, and store information
1100         related to them.  Hence we need to know their number, and adjust
1101         memory allocations.
1102
1103         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1104         static.
1105         * src/LR0.c (allocate_itemsets): The memory allocated to
1106         `symbol_count' was used for two different purpose: once to count
1107         the number of occurrences of each symbol, and later reassigned to
1108         `shift_symbol', containing the symbol that can be shifted from a
1109         given state.
1110         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1111         only, and...
1112         (new_itemsets): Allocate `shift_symbol' here.
1113         (allocate_itemsets): symbol_count includes useless nonterminals.
1114         Make room for them.
1115         (free_storage): Use `free', not `XFREE', for pointers that cannot
1116         be null.

1118 2001-12-05  Akim Demaille  <akim@epita.fr>
1119
1120         * src/nullable.c (set_nullable): Deobfuscate the handling of
1121         ritem.
1122         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1123
1124 2001-12-05  Akim Demaille  <akim@epita.fr>
1125
1126         * src/gram.c, src/gram.h (ritem_print): New.
1127         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1128         (This useless function was defined only to work around VMS linkers
1129         that can't handle compilation units with variables only).
1130         * src/reduce.c (dump_grammar): Use it to trace the construction of
1131         ritem.
1132
1133 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1134
1135         * src/bison.simple (union yyalloc): Change member names
1136         to be the same as the stack names.
1137         (yyparse): yyptr is now union yyalloc *, not char *.
1138         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1139         and may generate better code on some machines.
1140         (yystpcpy): Use prototype if __STDC__ is defined, not just
1141         if __cplusplus is defined.
1142
1143 2001-11-30  Akim Demaille  <akim@epita.fr>
1144
1145         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1146         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1147         Gettext doesn't compile cleanly, and dies with -Werror.
1148         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1149         Include WARNING_CFLAGS here.
1150         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1151         before being defined.
1152
1153 2001-11-27  Paul Eggert  <eggert@twinsun.com>

1157         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1158         (SIZE_MAX, UINT_MAX): New macros.
1159         (quotearg_n_options): Abort if N is negative.
1160         Avoid overflow check on hosts where size_t is 64 bits and int
1161         is 32 bits, as overflow is impossible there.
1162         Fix off-by-one typo that caused unnecessary reallocation.
1163
1164 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1165
1166         Name space cleanup in generated parser.
1167
1168         * doc/bison.texinfo (Bison Parser): Discuss system headers
1169         and their effect on the user name space.
1170
1171         * src/bison.simple:
1172         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1173         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1174         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1175
1176         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1177         on user names when possible.
1178
1179         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1180         Simplify test for whather <alloca.h> exists.
1181
1182         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1183
1184         (<stdio.h>): Include if YYDEBUG.
1185
1186         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1187         ! defined (yyoverflow) && ! defined (yymemcpy).
1188
1189         (yymemcpy, yyparse): Rename local variables as needed so that
1190         they all begin with 'yy'.
1191
1192         (yystrlen, yystpcpy): New functions.
1193
1194         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1195         All uses changed.
1196
1197         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1198         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1199         and YYSTACK_FREE instead of malloc and free.
1200
1201 2001-11-30  Akim Demaille  <akim@epita.fr>
1202
1203         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1204         before their first uses.

1210
1211 2001-11-30  Akim Demaille  <akim@epita.fr>
1212
1213         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1214         if body instead of `;' to pacify GCC's warnings.
1215
1216 2001-11-30  Akim Demaille  <akim@epita.fr>
1217
1218         Instead of mapping the LHS of unused rules to -1, keep the LHS
1219         valid, but flag the rules as invalid.
1220
1221         * src/gram.h (rule_t): `useful' is a new member.
1222         * src/print.c (print_grammar): Adjust.

1236
1237         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1238         useless nonterminals, move them at the end of the symbol arrays.
1239         (reduce_output): Adjust.
1240         * tests/reduce.at (Useless Nonterminals): Adjust.
1241
1242 2001-11-30  Akim Demaille  <akim@epita.fr>

1245         (nonterminals_reduce): New, extracted from...
1246         (reduce_grammar_tables): here.
1247         (reduce_grammar): Call nonterminals_reduce.
1248
1249 2001-11-29  Paul Eggert  <eggert@twinsun.com>

1252         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1253         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1254         New macros.
1255         (union yyalloc): New type.
1256         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1257         an arbitrary restriction on hosts where size_t is wider than int.
1258
1259         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1260         a parser stack overflow.  Allocate just one block of memory for all
1261         three stacks, instead of allocating three blocks; this typically is
1262         faster and reduces fragmentation.
1263
1264         Do not limit the number of items in the stack to a value that fits
1265         in 'int', as this is an arbitrary limit on hosts with 64-bit
1266         size_t and 32-bit int.
1267
1268 2001-11-29  Marc Autret  <autret_m@epita.fr>

1317

1319         keep ruleno only.
1320
1321 2001-11-28  Akim Demaille  <akim@epita.fr>
1322
1323         * src/closure.c (closure): Instead of looping over word in array
1324         then bits in words, loop over bits in array.
1325
1326 2001-11-28  Akim Demaille  <akim@epita.fr>
1327
1328         * src/closure.c (closure): No longer optimize the special case
1329         where all the bits of `ruleset[r]' are set to 0, to make the code
1330         clearer.
1331
1332 2001-11-28  Akim Demaille  <akim@epita.fr>
1333

1465 2001-11-23  Akim Demaille  <akim@epita.fr>
1466
1467         Attaching lineno to buckets is stupid, since only one copy of each

2645
2646         * src/bison.simple (yyparse): Don't take the address of an

2656         completely wrong.

2695         bound to true.
2696         (read_declarations): Add case for macro definition.
2697         (copy_identifier): New.
2698         (parse_macro_decl): Read macro identifiers using copy_identifier

2705         (output_parser): Fix bug on '%%line' directives.

2718         table with a macro. No output to the table obstack.
2719         (output_gram): Same for 'rhs' and 'prhs'.

2733         with something new. Skeletons are now processed character by character
2734         rather than line by line, and Bison looks for '%%' macros. This is the
2735         first step in making Bison's output process (a lot) more flexible.
2736         (output_parser): Use the macro table.

3064
3065         * src/reader.c (gensym): `gensym_count' is your own.
3066         Use a static buf to create the symbol name, as token_buffer is no

3070
3071         * src/conflicts.c (conflict_report): Be sure not to append to res

3078         New, from fileutils 4.0.37.
3079         * configure.in: Require Autoconf 2.49c.  I took some time before
3080         making this decision.  This is the only way out for portability
3081         issues in Bison, it would mean way too much duplicate effort to
3082         import in Bison features implemented in 2.49c since 2.13.
3083         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3096         (init_lex): Initialize it.  No longer call...

3101
3102         * src/lex.h: Rename all the tokens:

3104         s/\bIDENTIFIER\b/tok_identifier/g;
3105         etc.
3106         Let them be enums, not #define, to ease debugging.
3107         Adjust all the code.
3108
3109 2001-01-18  Akim Demaille  <akim@epita.fr>
3110
3111         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

3113
3114 2001-01-18  Akim Demaille  <akim@epita.fr>
3115
3116         Since we now use obstacks, more % directives can be enabled.
3117
3118         * src/lex.c (percent_table): Also accept `%yacc',
3119         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3120         `%debug'.
3121         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3122         instead of returning a token.
3123         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3124         * src/reader.c (read_declarations): Adjust.
3125         * src/files.c (open_files): Don't call `compute_base_names', don't
3126         compute `attrsfile' since they depend upon data which might be
3127         *in* the input file now.
3128         (output_files): Do it here.
3129         * src/output.c (output_headers): Document the fact that this patch
3130         introduces a guaranteed SEGV for semantic parsers.
3131         * doc/bison.texinfo: Document them.

3155         FILE * parameters.
3156
3157 2000-12-20  Akim Demaille  <akim@epita.fr>
3158
3159         * src/files.c (open_files): Actually the `.output' file is based
3160         on the short_base_name, not base_name.
3161         * tests/suite.at (Checking output file names): Adjust.
3162
3163 2000-12-20  Akim Demaille  <akim@epita.fr>
3164
3165         * src/bison.s1: Remove, we now use directly...

3189         (stringappend): Be just like strcat but allocate.
3190         (base_names): Eve out from open_files.
3191         Try to simplify the rather hairy computation of base_name and
3192         short_base_name.
3193         (open_files): Use it.
3194         * tests/suite.at (Checking output file names): New test.

3204
3205 2000-12-19  Akim Demaille  <akim@epita.fr>
3206

3208         there are.

3211
3212 2000-12-19  Akim Demaille  <akim@epita.fr>
3213
3214         Let the handling of the skeleton files be local to the procedures
3215         that use it.

3244
3245         * src/bison.s1 (YYLLOC_DEFAULT): New macro.
3246         Provide a default definition.
3247         Use it when executing the default @ action.
3248         * src/reader.c (reader_output_yylsp): No longer include
3249         `timestamp' and `text' in the default YYLTYPE.

3260         to escape special characters when outputting filenames.
3261         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.
3262         (output_headers): Don't depend on them, Use ACTSTR.

3264 2000-11-17  Akim Demaille  <akim@epita.fr>
3265
3266         * lib/obstack.h: Formatting changes.
3267         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3268         prevents type checking.
3269         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3270         cast the value to (void *): assigning a `foo *' to a `void *'
3271         variable is valid.
3272         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3273         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3308
3309 2000-11-07  Akim Demaille  <akim@epita.fr>
3310
3311         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3312         Merge in a single CPP if/else.

3321         `address' for consistency.  Qualify it `const'.

3323         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
3324         `const' their input argument (`data' or `address').

3333 2000-11-03  Akim Demaille  <akim@epita.fr>

3335         For some reason, this was not applied.
3336

3353         * src/main.c (main): Don't use `atexit' to register `done', since
3354         it no longer has to remove tmp files, just call `output_files'
3355         when there are no errors.
3356
3357 2000-11-02  Akim Demaille  <akim@epita.fr>

3459
3460         When a literal string is used to define two different tokens,
3461         `bison -v' segfaults.
3462         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3463
3464         * tests/regression.m4: New file.
3465         Include the core of the sample provided by Piotr Gackiewicz.
3466         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3467         properly.
3468
3469 2000-10-04  Akim Demaille  <akim@epita.fr>
3470
3471         * src/reader.c (parse_expect_decl): Keep `count' within the size
3472         of `buffer'.
3473         From Neil Booth.
3474
3475 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3476
3477         * bison.s1 (yyparse): Assign the default value
3478         unconditionally, to avoid a GCC warning and make the parser a
3479         tad smaller.
3480
3481 2000-10-02  Akim Demaille  <akim@epita.fr>
3482
3483         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3484         options.

3487
3488         * src/derives.c, src/print.c, src/reduce.c: To ease the

3490
3491 2000-10-02  Akim Demaille  <akim@epita.fr>
3492
3493         The location tracking mechanism is precious for parse error
3494         messages.  Nevertheless, it is enabled only when `@n' is used in
3495         the grammar, which is a different issue (you can use it in error
3496         message, but not in the grammar per se).  Therefore, there should
3497         be another means to enable it.
3498
3499         * src/getargs.c (getargs): Support `--locations'.
3500         (usage): Report it.
3501         * src/getargs.h (locationsflag): Export it.
3502         * src/lex.c (percent_table): Support `%locations'.
3503         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3504         with `locationsflag'.
3505         * doc/bison.texinfo: Document `--locations' and `%locations'.
3506         Sort the options.
3507         * tests/calc.m4: Test it.
3508
3509         For regularity of the names, replace each
3510         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3511         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3512         In addition replace each `flag' with `_flag'.
3513
3514 2000-10-02  Akim Demaille  <akim@epita.fr>
3515
3516         Also test parse error messages, including with YYERROR_VERBOSE.
3517
3518         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3519         associative).
3520         Use it to check the computations.
3521         Use it to check `nonassoc' is honored.
3522         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3523         `--yyerror-verbose'.
3524         (_AT_CHECK_CALC): Adjust to this option.
3525         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3526
3527 2000-10-02  Akim Demaille  <akim@epita.fr>
3528
3529         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3530         the latter demonstrates a flaw in the handling of non debugging
3531         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3532         was used in order to simplify:
3533
3534         #if YYDEBUG
3535         if (yydebug)
3536         {
3537         ...
3538         }
3539         #endif
3540
3541         into
3542
3543         if (yydebug)
3544         {
3545         ...
3546         }
3547
3548         unfortunately this leads to a CPP conflict when
3549         `--name-prefix=foo' is used since it produces `#define yydebug
3550         foodebug'.
3551
3552         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3553         (YYDPRINTF): New macro.
3554         Spread its use.
3555         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3556         the bison options.
3557         Also test `--verbose', `--defines' and `--name-prefix'.
3558
3559 2000-10-02  Akim Demaille  <akim@epita.fr>
3560
3561         Improve the readability of the produced parsers.
3562
3563         * src/bison.s1: Formatting changes.
3564         Improve the comment related to the `$' mark.
3565         (yydefault): Don't fall through to `yyresume': `goto' there.
3566         * src/output.c (output_parser): When the `$' is met, skip the end
3567         of its line.
3568         New variable, `number_of_dollar_signs', to check there's exactly
3569         one `$' in the parser skeleton.
3570
3571 2000-10-02  Akim Demaille  <akim@epita.fr>
3572
3573         * lib/xstrdup.c: New file, from the fileutils.
3574         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3575         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3576         instead of strlen + xmalloc + strcpy.
3577         * src/symtab.c (copys): Remove, use xstrdup instead.
3578
3579 2000-10-02  Akim Demaille  <akim@epita.fr>
3580
3581         * src/gram.h (associativity): New enum type which replaces the
3582         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3583         `right_assoc', `left_assoc' and `non_assoc'.
3584         Adjust all dependencies.
3585         * src/reader.c: Formatting changes.
3586         (LTYPESTR): Don't define it, use it as a literal in
3587         `reader_output_yylsp'.
3588         * src/symtab.h (symbol_class): New enum type which replaces the
3589         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3590         `sunknown', `stoken and `snterm'.
3591
3592 2000-10-02  Akim Demaille  <akim@epita.fr>
3593
3594         * src/getargs.c (fixed_outfiles): Rename as...
3595         (yaccflag): for consistency and accuracy.
3596         Adjust dependencies.
3597
3598 2000-10-02  Akim Demaille  <akim@epita.fr>
3599
3600         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3601         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3602         difficult and introduced a lot of core dump.  It turns out that
3603         Bison used an implementation of `xmalloc' based on `calloc', and
3604         at various places it does depend upon the initialization to 0.  I
3605         have not tried to isolate the pertinent places, and all the former
3606         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3607         someone should address this issue.

3709
3710         `user_toknums' is output as a `short[]' in `output.c', while it is
3711         defined as a `int[]' in `reader.c'.  For consistency with the

3757         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

3759         definitions in config.h.

3972         (copy_action): Use it.
3973         (copy_guard): Likewise.
3974
3975 2000-03-17  Akim Demaille  <akim@epita.fr>
3976
3977         Change the handling of @s so that they behave exactly like $s.
3978         There is now a pseudo variable @$ (readble and writable), location
3979         of the lhs of the rule (by default ranging from the location of
3980         the first symbol of the rhs, to the location of the last symbol,
3981         or, if the rhs is empty, YYLLOC).
3982
3983         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3984         yyval.
3985         (yyparse): When providing a default semantic action, provide a
3986         default location action.
3987         (after the $): No longer change `*YYLSP', just stack YYLOC the
3988         same way you stack YYVAL.
3989         * src/reader.c (read_declarations): Use warns.
3990         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3991         (copy_action, case '@'): Likewise.
3992         Use a standard error message, to save useless work from
3993         translators.
3994
3995 2000-03-17  Akim Demaille  <akim@epita.fr>
3996

4014
4015         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4016         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4017         One `#if YYDEBUG' remains, since it uses variables which are
4018         defined only if `YYDEBUG != 0'.
4019

4046         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
4047         autoheader.

4052         the proper line number and file name.
4053         (DEFS): Propagate the location of bison library files and of the
4054         locale files.
4055         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4056         builddir.
4057         * acinclude.m4: Remove, replaced by the directory m4.
4058         * m4/Makefile.am (EXTRA_DIST): New variable.

4738         (lex): Implemented "..." tokens.
4739         (literalchar, lex, parse_percent_token): Made tokenbuffer
4740         always contain the token.  This includes growing the token
4741         buffer while reading an integer.
4742         (parse_percent_token): Replaced if-else statement with percent_table.
4743         (parse_percent_token): Added % declarations as another
4744         way to specify the flags -n, -l, and -r.  Also added hooks for
4745         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4746         major changes to files.c.
4747         (lex) Retain in the incoming stream a character following
4748         an incorrect '/'.
4749         (skip_white_space, lex):  Revised most error messages
4750         and changed fatal to warn to avoid aborting.
4751         (percent_table):  Added %thong declarations.
