   3         * src/reader.c, src/reader.h (user_toknums): Remove.
   4         Adjust all users to use symbols[i]->user_token_number.
   5
   6
   7 2001-12-29  Akim Demaille  <akim@epita.fr>
   8
   9         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
  10         Adjust all users to use symbols[i]->prec or ->assoc.
  11
  12
  13 2001-12-29  Akim Demaille  <akim@epita.fr>
  14
  15         * src/reader.c, src/reader.h (tags): Remove.
  16         Adjust all users to use symbols[i]->tag.
  17
  18
  19 2001-12-29  Akim Demaille  <akim@epita.fr>
  20
  21         * src/gram.h, src/gram.c (symbols): New, similar to state_table
  22         and rule_table.
  23         * src/reader.c (packsymbols): Fill this table.
  24         Drop sprec.
  25         * src/conflicts.c (resolve_sr_conflict): Adjust.
  26         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
  27         single table.
  28         Use symbols[i]->tag instead of tags[i].
  29
  30
  31 2001-12-29  Akim Demaille  <akim@epita.fr>
  32
  33         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
  34         In addition, put a comment in there, to replace...
  35         * tests/regression.at (%union and C comments): Remove.
  36
  37
  38 2001-12-29  Akim Demaille  <akim@epita.fr>
  39
  40         * tests/regression.at (Web2c Actions): Blindly move the actual
  41         output as expected output.  The contents *seem* right to me, but I
  42         can't pretend reading perfectly parser tables...  Nonetheless, all
  43         the other tests pass correctly, the table look OK, even though the
  44         presence of `$axiom' is to be noted: AFAICS it is useless (but
  45         harmless).
  46
  47
  48 2001-12-29  Akim Demaille  <akim@epita.fr>
  49
  50         * src/reader.c (readgram): Don't add the rule 0 if there were no
  51         rules read.  In other words, add it _after_ having performed
  52         grammar sanity checks.
  53         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
  54
  55
  56 2001-12-29  Akim Demaille  <akim@epita.fr>
  57
  58         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
  59         visible, and some states have now a different number.
  60
  61
  62 2001-12-29  Akim Demaille  <akim@epita.fr>
  63
  64         * src/reader.c (readgram): Bind the initial rule's lineno to that
  65         of the first rule.
  66         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
  67         (Solved SR Conflicts): Adjust rule 0's line number.
  68
  69
  70 2001-12-29  Akim Demaille  <akim@epita.fr>
  71
  72         Fix the `GAWK Grammar' failure.
  73
  74         * src/LR0.c (final_state): Initialize to -1 so that we do compute
  75         the reductions of the first state which was mistakenly confused
  76         with the final state because precisely final_state was initialized
  77         to 0.
  78         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
  79         now noticed by Bison.
  80         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
  81         have a reduction on $default.
  82
  83
  84 2001-12-29  Akim Demaille  <akim@epita.fr>
  85
  86         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
  87         rule line numbers.
  88         * src/closure.c (print_closure): Likewise.
  89         * src/derives.c (print_derives): Likewise.
  90         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
  91         now.
  92
  93 2001-12-29  Akim Demaille  <akim@epita.fr>
  94
  95         * src/lalr.c (lookaheads_print): New.
  96         (lalr): Call it when --trace-flag.
  97         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
  98         are dumped.
  99
 100
 101 2001-12-29  Akim Demaille  <akim@epita.fr>
 102
 103         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 104         when walking through ritem, even via rule->rhs.
 105         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 106         (useful_production, useless_nonterminals): Likewise.
 107         (reduce_grammar_tables): Likewise, plus update nritems.
 108         * src/nullable.c (set_nullable): Likewise.
 109         * src/lalr.c (build_relations): Likewise.
 110         * tests/sets.at (Nullable): Adjust.
 111         Fortunately, now, the $axiom is no longer nullable.
 112
 113
 114 2001-12-29  Akim Demaille  <akim@epita.fr>
 115
 116         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 117         the 0-sentinel.
 118         * src/gram.c (ritem_longest_rhs): Likewise.
 119         * src/reduce.c (nonterminals_reduce): Likewise.
 120         * src/print_graph.c (print_graph): Likewise.
 121         * src/output.c (output_rule_data): Likewise.
 122         * src/nullable.c (set_nullable):  Likewise.
 123
 124 2001-12-29  Akim Demaille  <akim@epita.fr>
 125
 126         * src/output.c: Comment changes.
 127
 128 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 129
 130         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 131         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 132         Sparc, as they were causing more porting problems than the
 133         (minor) performance improvement was worth.
 134
 135         Also, catch up with 1.31's YYSTD.
 136
 137 2001-12-27  Akim Demaille  <akim@epita.fr>
 138
 139         * src/output.c (output_gram): Rely on nritems, not the
 140         0-sentinel.  See below.
 141         Use -1 as separator, not 0.
 142         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 143         Rely on -1 as separator in yyrhs, instead of 0.
 144         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 145         twice `Now at end of input', therefore there are two lines less to
 146         expect.
 147
 148 2001-12-27  Akim Demaille  <akim@epita.fr>
 149
 150         * tests/regression.at (Unresolved SR Conflicts):
 151         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 152         below.
 153
 154 2001-12-27  Akim Demaille  <akim@epita.fr>
 155
 156         * src/LR0.c (new_state): Recognize the final state by the fact it
 157         is reached by eoftoken.
 158         (insert_start_shifting_state, insert_eof_shifting_state)
 159         (insert_accepting_state, augment_automaton): Remove, since now
 160         these states are automatically computed from the initial state.
 161         (generate_states): Adjust.
 162         * src/print.c: When reporting a rule number to the user, substract
 163         1, so that the axiom rule is rule 0, and the first user rule is 1.
 164         * src/reduce.c: Likewise.
 165         * src/print_graph.c (print_core): For the time being, just as for
 166         the report, depend upon --trace-flags to dump the full set of
 167         items.
 168         * src/reader.c (readgram): Once the grammar read, insert the rule
 169         0: `$axiom: START-SYMBOL $'.
 170         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 171         number of the states has changed (the final state is no longer
 172         necessarily the last), catch up.
 173
 174 2001-12-27  Akim Demaille  <akim@epita.fr>
 175
 176         Try to make the use of the eoftoken valid.  Given that its value
 177         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 178         is used instead of > 0 where appropriate, (ii), depend upon nritems
 179         instead of the 0-sentinel.
 180
 181         * src/gram.h, src/gram.c (nritems): New.
 182         Expected to be duplication of nitems, but for the time being...
 183         * src/reader.c (packgram): Assert nritems and nitems are equal.
 184         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 185         * src/closure.c (print_closure, print_fderives): Likewise.
 186         * src/gram.c (ritem_print): Likewise.
 187         * src/print.c (print_core, print_grammar): Likewise.
 188         * src/print_graph.c: Likewise.
 189
 190 2001-12-27  Akim Demaille  <akim@epita.fr>
 191
 192         * src/main.c (main): If there are complains after grammar
 193         reductions, then output the report anyway if requested, then die.
 194         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 195         * src/reader.c (eoftoken): New.
 196         (parse_token_decl): If the token being defined has value `0', it
 197         is the eoftoken.
 198         (packsymbols): No longer hack `tags' to insert `$' by hand.
 199         Be sure to preserve the value of the eoftoken.
 200         (reader): Make sure eoftoken is defined.
 201         Initialize nsyms to 0: now eoftoken is created just like the others.
 202         * src/print.c (print_grammar): Don't special case the eof token.
 203         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 204         lie anyway, albeit pleasant.
 205         * tests/calc.at: Exercise error messages with eoftoken.
 206         Change the grammar so that empty input is invalid.
 207         Adjust expectations.
 208         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 209
 210 2001-12-27  Akim Demaille  <akim@epita.fr>
 211
 212         * configure.in: Check the protos of strchr ans strspn.
 213         Replace strchr if needed.
 214         * src/system.h: Provide the protos of strchr, strspn and memchr if
 215         missing.
 216         * lib/strchr.c: New.
 217         * src/reader.c (symbols_save): Use strchr.
 218
 219 2001-12-27  Akim Demaille  <akim@epita.fr>
 220
 221         * src/print.c, src/print_graph.c (escape): New.
 222         Use it to quote the TAGS outputs.
 223         * src/print_graph.c (print_state): Now errors are in red, and
 224         reductions in green.
 225         Prefer high to wide: output the state number on a line of its own.
 226
 227 2001-12-27  Akim Demaille  <akim@epita.fr>
 228
 229         * src/state.h, src/state.c (reductions_new): New.
 230         * src/LR0.c (set_state_table): Let all the states have a
 231         `reductions', even if reduced to 0.
 232         (save_reductions): Adjust.
 233         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 234         * src/print.c (print_reductions, print_actions): Adjust.
 235         * src/output.c (action_row): Adjust.
 236
 237 2001-12-27  Akim Demaille  <akim@epita.fr>
 238
 239         * src/state.h, src/state.c (errs_new, errs_dup): New.
 240         * src/LR0.c (set_state_table): Let all the states have an errs,
 241         even if reduced to 0.
 242         * src/print.c (print_errs, print_reductions): Adjust.
 243         * src/output.c (output_actions, action_row): Adjust.
 244         * src/conflicts.c (resolve_sr_conflict): Adjust.
 245
 246 2001-12-27  Akim Demaille  <akim@epita.fr>
 247
 248         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 249
 250 2001-12-27  Akim Demaille  <akim@epita.fr>
 251
 252         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 253         * src/print.c: here.
 254         (lookaheadset, shiftset): New, used as additional storage by
 255         print_reductions.
 256         (print_results): Adjust.
 257         (print_shifts, print_gotos, print_errs): New, extracted from...
 258         (print_actions): here.
 259         * src/print_graph.c (print_actions): Remove dead code.
 260
 261 2001-12-27  Akim Demaille  <akim@epita.fr>
 262
 263         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 264         `$n' and `@n'.
 265
 266 2001-12-27  Akim Demaille  <akim@epita.fr>
 267
 268         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 269         (build_relations): Adjust.
 270
 271 2001-12-27  Akim Demaille  <akim@epita.fr>
 272
 273         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 274         duplication.
 275
 276 2001-12-27  Akim Demaille  <akim@epita.fr>
 277
 278         * src/reader.c (packgram): Catch nitems overflows.
 279
 280 2001-12-27  Akim Demaille  <akim@epita.fr>
 281
 282         * src/files.c, src/files.h (guard_obstack): Remove.
 283         * src/output.c (output): Adjust.
 284         * src/reader.c (parse_braces): New, factoring...
 285         (copy_action, copy_guard): these two which are renamed as...
 286         (parse_action, parse_guard): these.
 287         As a voluntary consequence, using braces around guards is now
 288         mandatory.
 289
 290 2001-12-27  Akim Demaille  <akim@epita.fr>
 291
 292         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 293         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 294         members.
 295         (symbol_list_new): Adjust.
 296         (copy_action): action_line is the first line, not the last.
 297         (copy_guard): Just as for actions, store the `action' only, not
 298         the switch/case/break flesh.
 299         Don't parse the user action that might follow the guard, let...
 300         (readgram): do it, i.e., now, there can be an action after a
 301         guard.
 302         In other words the guard is just explicitly optional.
 303         (packgram): Adjust.
 304         * src/output.c (guards_output): New.
 305         (output_parser): Call it when needed.
 306         (output): Also free the guard and attrs obstacks.
 307         * src/files.c, src/files.h (obstack_save): Remove.
 308         (output_files): Remove.
 309         As a result, if one needs the former `.act' file, using an
 310         appropriate skeleton which requires actions and guards is now
 311         required.
 312         * src/main.c (main): Adjust.
 313         * tests/semantic.at: New.
 314         * tests/regression.at: Use `input.y' as input file name.
 315         Avoid 8+3 problems by requiring input.c when the test needs the
 316         parser.
 317
 318 2001-12-27  Akim Demaille  <akim@epita.fr>
 319
 320         * src/reader.c (symbol_list_new): Be sure to initialize all the
 321         fields.
 322
 323 2001-12-27  Akim Demaille  <akim@epita.fr>
 324
 325         All the hacks using a final pseudo state are now useless.
 326
 327         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 328         * src/lalr.c (nLA): New.
 329         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 330         instead of lookaheadsp from the pseudo state (nstate + 1).
 331
 332 2001-12-27  Akim Demaille  <akim@epita.fr>
 333
 334         * src/output.c (action_row, token_actions): Use a state_t instead
 335         of a integer, and nlookaheads instead of the following state's
 336         lookaheadsp.
 337
 338 2001-12-27  Akim Demaille  <akim@epita.fr>
 339
 340         * src/conflicts.c (log_resolution, flush_shift)
 341         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 342         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 343         (conflicts_print, print_reductions): Use a state_t instead of an
 344         integer when referring to a state.
 345         As much as possible, depend upon nlookaheads, instead of the
 346         `lookaheadsp' member of the following state (since lookaheads of
 347         successive states are successive, the difference between state n + 1
 348         and n served as the number of lookaheads for state n).
 349         * src/lalr.c (add_lookback_edge): Likewise.
 350         * src/print.c (print_core, print_actions, print_state)
 351         (print_results): Likewise.
 352         * src/print_graph.c (print_core, print_actions, print_state)
 353         (print_graph): Likewise.
 354         * src/conflicts.h: Adjust.
 355
 356 2001-12-27  Akim Demaille  <akim@epita.fr>
 357
 358         * src/bison.hairy: Formatting/comment changes.
 359         ANSIfy.
 360         Remove `register' indications.
 361         Add plenty of `static'.
 362
 363 2001-12-27  Akim Demaille  <akim@epita.fr>
 364
 365         * src/output.c (prepare): Drop the muscle `ntbase' which
 366         duplicates ntokens.
 367         * src/bison.simple: Formatting/comment changes.
 368         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 369         is an undocumented synonym.
 370
 371 2001-12-22  Akim Demaille  <akim@epita.fr>
 372
 373         * src/output.c (output_table_data): Change the prototype to use
 374         `int' for array ranges: some invocations do pass an int, not a
 375         short.
 376         Reported by Wayne Green.

 378 2001-12-22  Akim Demaille  <akim@epita.fr>
 379
 380         Some actions of web2c.y are improperly triggered.
 381         Reported by Mike Castle.
 382
 383         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 384         * tests/regression.at (Web2c): Rename as...
 385         (Web2c Report): this.
 386         (Web2c Actions): New.
 387
 388 2001-12-22  Akim Demaille  <akim@epita.fr>
 389
 390         Reductions in web2c.y are improperly reported.
 391         Reported by Mike Castle.
 392
 393         * src/conflicts.c (print_reductions): Fix.
 394         * tests/regression.at (Web2c): New.
 395
 396 2001-12-18  Akim Demaille  <akim@epita.fr>
 397
 398         Some host fail on `assert (!"foo")', which expands to
 399         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 400         Reported by Nelson Beebee.
 401
 402         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 403         `#define it_succeeded 0' and `assert (it_succeeded)'.
 404
 405 2001-12-17  Marc Autret  <autret_m@epita.fr>
 406
 407         * src/bison.simple: Don't hard code the skeleton line and filename.
 408         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 409         New line counter 'skeleton_line' (skeleton-line muscle).
 410
 411 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 412
 413         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 414         YYDEBUG must be defined to a nonzero value.
 415
 416         * src/bison.simple (yytname): Do not assume that the user defines
 417         YYDEBUG to a properly parenthesized expression.
 418
 419 2001-12-17  Akim Demaille  <akim@epita.fr>
 420
 421         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 422         nlookaheads is a new member.
 423         Adjust all users.
 424         * src/lalr.h (nlookaheads): Remove this orphan declaration.
 425         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 426         state.
 427
 428 2001-12-17  Akim Demaille  <akim@epita.fr>
 429
 430         * src/files.h, src/files.c (open_files, close_files): Remove.
 431         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 432         let...
 433         * src/reader.c (reader): Do it.
 434
 435 2001-12-17  Akim Demaille  <akim@epita.fr>
 436
 437         * src/conflicts.c (print_reductions): Formatting changes.
 438
 439 2001-12-17  Akim Demaille  <akim@epita.fr>
 440
 441         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 442         (flush_reduce): New.
 443         (resolve_sr_conflict): Adjust.
 444
 445 2001-12-17  Akim Demaille  <akim@epita.fr>
 446
 447         * src/output.c (output_obstack): Be static and rename as...
 448         (format_obstack): this, to avoid any confusion with files.c's
 449         output_obstack.
 450         * src/reader.h (muscle_obstack): Move to...
 451         * src/output.h: here, since it's defined in output.c.
 452
 453 2001-12-17  Akim Demaille  <akim@epita.fr>
 454
 455         * src/output.c (action_row, save_column, default_goto)
 456         (sort_actions, matching_state, pack_vector): Better variable
 457         locality.
 458
 459 2001-12-17  Akim Demaille  <akim@epita.fr>
 460
 461         * src/output.c: Various formatting changes.
 462
 463 2001-12-17  Akim Demaille  <akim@epita.fr>
 464
 465         * src/files.c (output_files): Free the output_obstack.
 466         * src/main.c (main): Call print and print_graph conditionally.
 467         * src/print.c (print): Work unconditionally.
 468         * src/print_graph.c (print_graph): Work unconditionally.
 469         * src/conflicts.c (log_resolution): Output only if verbose_flag.
 470
 471 2001-12-16  Marc Autret  <autret_m@epita.fr>
 472
 473         * src/output.c (actions_output): Fix. When we use %no-lines,
 474         there is one less line per action.
 475
 476 2001-12-16  Marc Autret  <autret_m@epita.fr>
 477
 478         * src/bison.simple: Remove a useless #line directive.
 479         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 480         * src/output.c (get_lines_number): New.
 481         (output_parser): Adjust, now takes care about the lines of a
 482         output muscles.
 483         Fix line numbering.
 484         (actions_output): Computes the number of lines taken by actions.
 485         (output_master_parser): Insert new skeleton which is the name of
 486         the output parser file name.
 487
 488 2001-12-15  Marc Autret  <autret_m@epita.fr>
 489
 490         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
 491
 492 2001-12-15  Marc Autret  <autret_m@epita.fr>
 493
 494         * src/output.c (output_gram): Keep track of the hairy one.
 495
 496 2001-12-15  Akim Demaille  <akim@epita.fr>
 497
 498         Make `make distcheck' work.
 499
 500         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 501         system.h which uses libgettext.h.
 502
 503 2001-12-15  Akim Demaille  <akim@epita.fr>
 504
 505         * src/nullable.c (set_nullable): Useless rules must be skipped,
 506         otherwise, since we range over their symbols, we might look at a
 507         nonterminal which no longer ``exists'', i.e., it is not counted in
 508         `nvars', hence we overflow our arrays.
 509
 510 2001-12-15  Akim Demaille  <akim@epita.fr>
 511
 512         The header can also be produced directly, without any obstack!
 513         Yahoo!
 514
 515         * src/files.c, src/files.h (defines_obstack): Remove.
 516         (compute_header_macro): Global.
 517         (defines_obstack_save): Remove.
 518         * src/reader.c (parse_union_decl): No longer output to
 519         defines_obstack: its content can be found in the `stype' muscle
 520         anyway.
 521         (output_token_translations): Merge into...
 522         (symbols_output): this.
 523         Rename as...
 524         (symbols_save): this.
 525         (reader): Adjust.
 526         * src/output.c (header_output): New.
 527         (output): Call it.
 528
 529 2001-12-15  Akim Demaille  <akim@epita.fr>
 530
 531         * src/reader.c (parse_union_decl): Instead of handling two obstack
 532         simultaneously, use one to define the `stype' muscle, and use the
 533         value of the latter to fill defines_obstack.
 534         (copy_comment): Remove.
 535         (copy_comment2): Work for a single obstack.
 536         Rename as...
 537         (copy_comment): this.
 538
 539 2001-12-15  Akim Demaille  <akim@epita.fr>
 540
 541         * src/lex.c, src/lex.h (xgetc): No longer static.
 542         * src/reader.c (parse_union_decl): Revamp.
 543
 544 2001-12-15  Akim Demaille  <akim@epita.fr>
 545
 546         Still making progress in separating Bison into (i) input, (ii)
 547         process, (iii) output: now we can directly output the parser file
 548         without using table_obstack at all.
 549
 550         * src/files.c, src/files.h (table_obstack): Bye bye.
 551         (parser_file_name): New.
 552         * src/files.c (compute_output_file_names): Compute it.
 553         * src/output.c (actions_output, output_parser)
 554         (output_master_parser): To a file instead of an obstack.
 555
 556 2001-12-15  Akim Demaille  <akim@epita.fr>
 557
 558         Attach actions to rules, instead of pre-outputting them to
 559         actions_obstack.
 560
 561         * src/gram.h (rule_t): action and action_line are new members.
 562         * src/reader.c (symbol_list): Likewise.
 563         (copy_action): Save the actions within the rule.
 564         (packgram): Save them in rule_table.
 565         * src/output.c (actions_output): New.
 566         (output_parser): Use it on `%%actions'.
 567         (output_rule_data): Don't free rule_table.
 568         (output): Do it.
 569         (prepare): Don't save the `action' muscle.
 570         * src/bison.simple: s/%%action/%%actions/.
 571
 572 2001-12-15  Akim Demaille  <akim@epita.fr>
 573
 574         * src/reader.c (copy_action): When --yacc, don't append a `;'
 575         to the user action: let it fail if lacking.
 576         Suggested by Arnold Robbins and Tom Tromey.
 577
 578 2001-12-14  Akim Demaille  <akim@epita.fr>
 579
 580         * src/lex.c (literalchar): Simply return the char you decoded, non
 581         longer mess around with obstacks and int pointers.
 582         Adjust all callers.
 583
 584 2001-12-14  Akim Demaille  <akim@epita.fr>
 585
 586         * src/lex.c (literalchar): Don't escape the special characters,
 587         just decode them, and keep them as char (before, eol was output as
 588         the 2 char string `\n' etc.).
 589         * src/output.c (output_rule_data): Use quotearg to output the
 590         token strings.
 591
 592 2001-12-13  Paul Eggert  <eggert@twinsun.com>
 593
 594         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
 595         Do not infringe on the global user namespace when using C++.
 596         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
 597         All uses of `fprintf' and `stderr' changed.
 598
 599         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
 600
 601 2001-12-13  Akim Demaille  <akim@epita.fr>
 602
 603         The computation of nullable is broken: it doesn't handle empty
 604         RHS's properly.
 605
 606         * tests/torture.at (GNU AWK Grammar): New.
 607         * tests/sets.at (Nullable): New.
 608         * src/nullable.c (set_nullable): Instead of blindly looping over
 609         `ritems', loop over the rules, and then over their rhs's.
 610
 611         Work around Autotest bugs.
 612
 613         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
 614         frame, because Autotest understand lines starting with a `+' as
 615         traces from the shell.  Then, they are not processed properly.
 616         Admittedly an Autotest bug, but we don't have time to wait for
 617         Autotest to catch up.
 618         * tests/regression.at (Broken Closure): Adjust to the new table
 619         frames.
 620         Move to...
 621         * tests/sets.at: here.
 622
 623 2001-12-13  Akim Demaille  <akim@epita.fr>
 624
 625         * src/closure.c (closure): Use nrules instead of playing tricks
 626         with BITS_PER_WORD.
 627
 628 2001-12-13  Akim Demaille  <akim@epita.fr>
 629
 630         * src/print.c (print_actions): Output the handling of `$' as the
 631         traces do: shifting the token EOF.  Before EOF was treated as a
 632         nonterminal.
 633         * tests/regression.at: Adjust some tests.
 634         * src/print_graph.c (print_core): Complete the set of items via
 635         closure.  The next-to-final and final states are still unsatisfying,
 636         but that's to be addressed elsewhere.
 637         No longer output the rule numbers, but do output the state number.
 638         A single loop for the shifts + gotos is enough, but picked a
 639         distinct color for each.
 640         (print_graph): Initialize and finalize closure.
 641
 642 2001-12-13  Akim Demaille  <akim@epita.fr>
 643
 644         * src/reader.c (readgram): Remove dead code, an strip useless
 645         braces.
 646         (get_type): Remove, unused.
 647
 648 2001-12-12  Akim Demaille  <akim@epita.fr>
 649
 650         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 651         on that of lib/error.c.
 652
 653 2001-12-12  Akim Demaille  <akim@epita.fr>
 654
 655         Some hosts don't like `/' in includes.
 656
 657         * src/system.h: Include libgettext.h without qualifying the path.
 658         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 659         $(top_srcdir).
 660
 661 2001-12-11  Marc Autret  <autret_m@epita.fr>
 662
 663         * src/output.c (output_parser): Remove useless muscle.
 664
 665 2001-12-11  Marc Autret  <autret_m@epita.fr>
 666
 667         * src/bison.simple: Remove #line just before %%epilogue. It
 668         is now handled in ...
 669         * src/reader.c (read_additionnal_code): Add the output of a
 670         #line for the epilogue.
 671
 672 2001-12-10  Marc Autret  <autret_m@epita.fr>
 673
 674         * src/reader.c (copy_definition): Re-use CPP-outed code which
 675         replace precedent remove.
 676         * src/bison.simple: Remove #line before %%prologue because
 677         %%input-line is wrong at this time.
 678
 679 2001-12-10  Marc Autret  <autret_m@epita.fr>
 680
 681         * src/reader.c (symbols_output): Clean up.
 682         * src/output.c (output_gram, output): Clean up.
 683
 684 2001-12-10  Akim Demaille  <akim@epita.fr>
 685
 686         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 687         * src/LR0.c (set_state_table): here.
 688         * src/lalr.c (lalr): Call it.
 689
 690 2001-12-10  Akim Demaille  <akim@epita.fr>
 691
 692         * src/state.h (shifts): Remove the `number' member: shifts are
 693         attached to state, hence no longer need to be labelled with a
 694         state number.
 695
 696 2001-12-10  Akim Demaille  <akim@epita.fr>
 697
 698         Now that states have a complete set of members, the linked list of
 699         shifts is useless: just fill directly the state's shifts member.
 700
 701         * src/state.h (shifts): Remove the `next' member.
 702         * src/LR0.c (first_state, last_state): Remove.
 703         Adjust the callers.
 704         (augment_automaton): Don't look for the shifts that must be added
 705         a shift on EOF: it is those of the state we looked for!  But now,
 706         since shifts are attached, it is no longer needed to looking
 707         merely by its id: its number.
 708
 709 2001-12-10  Akim Demaille  <akim@epita.fr>
 710
 711         * src/LR0.c (augment_automaton): Better variable locality.
 712         Remove an impossible branch: if there is a state corresponding to
 713         the start symbol being shifted, then there is shift for the start
 714         symbol from the initial state.
 715
 716 2001-12-10  Akim Demaille  <akim@epita.fr>
 717
 718         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 719         only when appropriate: when insert_start_shifting_state' is not
 720         invoked.
 721         * tests/regression.at (Rule Line Numbers): Adjust.
 722
 723 2001-12-10  Akim Demaille  <akim@epita.fr>
 724
 725         * src/LR0.c (augment_automaton): Now that all states have shifts,
 726         merge the two cases addition shifts to the initial state.
 727
 728 2001-12-10  Akim Demaille  <akim@epita.fr>
 729
 730         * src/lalr.c (set_state_table): Move to...
 731         * src/LR0.c: here.
 732         * src/lalr.c (lalr): Don't call it...
 733         * src/LR0.c (generate_states): do it.
 734         * src/LR0.h (first_state): Remove, only the table is used.
 735
 736 2001-12-10  Akim Demaille  <akim@epita.fr>
 737
 738         * src/LR0.h (first_shift, first_reduction): Remove.
 739         * src/lalr.c: Don't use first_shift: find shifts through the
 740         states.
 741
 742 2001-12-10  Akim Demaille  <akim@epita.fr>
 743
 744         * src/LR0.c: Attach shifts to states as soon as they are
 745         computed.
 746         * src/lalr.c (set_state_table): Instead of assigning shifts to
 747         state, just assert that the mapping was properly done.
 748
 749 2001-12-10  Akim Demaille  <akim@epita.fr>
 750
 751         * src/LR0.c (insert_start_shift): Rename as...
 752         (insert_start_shifting_state): this.
 753         (insert_eof_shifting_state, insert_accepting_state): New.
 754         (augment_automaton): Adjust.
 755         Better locality of the variables.
 756         When looking if the start_symbol is shifted from the initial
 757         state, using `while (... symbol != start_symbol ...)' sounds
 758         better than `while (... symbol < start_symbol ...)': If fail
 759         to see how the order between symbols could be relevant!
 760
 761 2001-12-10  Akim Demaille  <akim@epita.fr>
 762
 763         * src/getargs.h: Don't declare `spec_name_prefix' and
 764         `spec_file_prefix', declared by src/files.h.
 765         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 766         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 767         * src/output.c (prepare): Adjust.
 768         * src/reader.c (symbols_output): Likewise.
 769         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 770
 771 2001-12-10  Akim Demaille  <akim@epita.fr>
 772
 773         * src/muscle_tab.c (muscle_init): NULL is a better default than
 774         `"0"'.
 775
 776 2001-12-10  Akim Demaille  <akim@epita.fr>
 777
 778         * src/reader.c (reader): Calling symbols_output once is enough.
 779
 780 2001-12-10  Akim Demaille  <akim@epita.fr>
 781
 782         Now that states have a complete set of members, the linked list of
 783         reductions is useless: just fill directly the state's reductions
 784         member.
 785
 786         * src/state.h (struct reductions): Remove member `number' and
 787         `next'.
 788         * src/LR0.c (first_reduction, last_reduction): Remove.
 789         (save_reductions): Don't link the new reductions, store them in
 790         this_state.
 791         * src/lalr.c (set_state_table): No need to attach reductions to
 792         states, it's already done.
 793         * src/output.c (output_actions): No longer free the shifts, then
 794         the reductions, then the states: free all the states and their
 795         members.
 796
 797 2001-12-10  Akim Demaille  <akim@epita.fr>
 798
 799         * src/options.c (OPTN, DRTV, BOTH): New.
 800         (option_table): Use them.
 801
 802         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 803         the job of system.h.
 804         * src/options.c: Don't include stdio.h and xalloc.h for the same
 805         reasons.
 806
 807 2001-12-10  Akim Demaille  <akim@epita.fr>
 808
 809         * src/output.c (output, prepare): Make sure the values of the
 810         muscles `action' and `prologue' are 0-terminated.
 811
 812 2001-12-10  Akim Demaille  <akim@epita.fr>
 813
 814         Clean up GCC warnings.
 815
 816         * src/reader.c (copy_action): `buf' is not used.
 817         (parse_skel_decl): Be static.
 818         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 819         * src/options.h (create_long_option_table): Have a real prototype.
 820         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 821         (hash_delete_at): Return const void *.
 822         Adjust casts to preserve the const.
 823
 824 2001-12-10  Akim Demaille  <akim@epita.fr>
 825
 826         * configure.in: Require 2.52g.
 827         M4 is not needed, but AUTOM4TE is.
 828         * m4/m4.m4: Remove.
 829         * tests/Makefile.am: Adjust.
 830
 831 2001-12-10  Akim Demaille  <akim@epita.fr>
 832
 833         One structure for states is enough, even though theoretically
 834         there are LR(0) states and LALR(1) states.
 835
 836         * src/lalr.h (state_t): Remove.
 837         (state_table): Be state_t **, not state_t *.
 838         * src/state.h (core, CORE_ALLOC): Rename as...
 839         (state_t, STATE_ALLOC): this.
 840         Add the LALR(1) members: shifts, reductions, errs.
 841         * src/LR0.c (state_table): Rename as...
 842         (state_hash): this, to avoid name clashes with the global
 843         `state_table'.
 844         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 845         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 846
 847 2001-12-10  Akim Demaille  <akim@epita.fr>
 848
 849         Bison dumps core on bash.y.
 850         Reported by Pascal Bart.
 851
 852         * src/warshall.c (bitmatrix_print): New.
 853         (TC): Use it.
 854         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 855         j must be the outer loop.
 856         * tests/regression.at (Broken Closure): New.
 857
 858 2001-12-05  Akim Demaille  <akim@epita.fr>
 859
 860         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 861         its argument.
 862         Reported by Peter Hámorský.
 863
 864 2001-12-05  Akim Demaille  <akim@epita.fr>
 865
 866         * src/conflicts.c (err_table): Remove.
 867         (resolve_sr_conflict): Adjust.
 868         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 869         Rename as...
 870         (state_t.reductions, state_t.shifts): this.
 871
 872 2001-12-05  Akim Demaille  <akim@epita.fr>
 873
 874         * src/reduce.c (reduce_grammar_tables): No longer disable the
 875         removal of useless rules via CPP but via `if (0)', so that the
 876         compiler still check the code is valid.
 877         For instance, it should have noticed `rline' no longer exists: use
 878         the `line' member of rule_t.
 879         * src/gram.c (dummy, rline): Remove, unused.
 880
 881 2001-12-05  Akim Demaille  <akim@epita.fr>
 882
 883         * src/output.c (pack_vector): Use assert, not berror.
 884         * src/main.c (berror): Remove, unused.
 885
 886 2001-12-05  Akim Demaille  <akim@epita.fr>
 887
 888         New experimental feature: if --verbose --trace output all the
 889         items of a state, not only its kernel.
 890
 891         * src/print.c (print_core): If `trace_flag', then invoke closure
 892         before outputting the items of the state (print_core is no longer
 893         a correct name them).
 894         (print_results): Invoke new_closure/free_closure if needed.
 895
 896 2001-12-05  Akim Demaille  <akim@epita.fr>
 897
 898         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 899         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 900         (nitemset): for consistency with the rest of the project.
 901
 902 2001-12-05  Akim Demaille  <akim@epita.fr>
 903
 904         * src/closure.c (print_closure): Improve.
 905         (closure): Use it for printing input and output.
 906
 907 2001-12-05  Akim Demaille  <akim@epita.fr>
 908
 909         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 910         indexed by nonterminals.
 911
 912 2001-12-05  Akim Demaille  <akim@epita.fr>
 913
 914         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 915         what it was!).
 916         * src/warshall.h: Remove accidental duplication of the content.
 917
 918 2001-12-05  Akim Demaille  <akim@epita.fr>
 919
 920         * src/closure.c (set_fderives): De-obfuscate.

 929
 930 2001-12-05  Akim Demaille  <akim@epita.fr>
 931
 932         * src/output.c (action_row): De-obfuscate
 933         using the good o' techniques: arrays not pointers, variable
 934         locality, BITISSET, RESETBIT etc.
 935
 936 2001-12-05  Akim Demaille  <akim@epita.fr>
 937
 938         Pessimize the code to simplify it: from now on, all the states
 939         have a valid SHIFTS, which NSHIFTS is possibly 0.
 940
 941         * src/LR0.c (shifts_new): Be global and move to..
 942         * src/state.c, src/state.h: here.
 943         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 944         * src/print_graph: Adjust.
 945
 946 2001-12-05  Akim Demaille  <akim@epita.fr>
 947
 948         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 949         * src/conflicts.c: Use it.
 950         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 951         incorrectly ``simplified''.
 952
 953 2001-12-05  Akim Demaille  <akim@epita.fr>
 954
 955         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
 956         using the good o' techniques: arrays not pointers, variable
 957         locality, BITISSET, RESETBIT etc.
 958
 959 2001-12-05  Akim Demaille  <akim@epita.fr>
 960
 961         * src/state.h (SHIFT_SYMBOL): New.
 962         * src/conflicts.c: Use it to deobfuscate.
 963
 964 2001-12-05  Akim Demaille  <akim@epita.fr>
 965
 966         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
 967         (print_reductions): De-obfuscate using the good o' techniques:
 968         arrays not pointers, variable locality, BITISSET.
 969
 970 2001-12-05  Akim Demaille  <akim@epita.fr>
 971
 972         * src/conflicts.c (print_reductions): Arrays, not pointers.
 973         Use BITISSET.
 974
 975 2001-12-05  Akim Demaille  <akim@epita.fr>
 976
 977         * src/conflicts.c (print_reductions): Pessimize, but clarify.

 980

 995
 996 2001-12-05  Akim Demaille  <akim@epita.fr>
 997
 998         * src/LR0.c (augment_automaton): Formatting changes.
 999         Better variable locality.
1000
1001 2001-12-05  Akim Demaille  <akim@epita.fr>
1002
1003         * src/lalr.c (matrix_print): New.
1004         (transpose): Use it.
1005         Use arrays instead of pointers.
1006
1007 2001-12-05  Akim Demaille  <akim@epita.fr>
1008
1009         * src/lalr.c (maxrhs): Move to...
1010         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1011         * src/lalr.c (build_relations): Adjust.
1012
1013 2001-12-05  Akim Demaille  <akim@epita.fr>
1014
1015         * src/lalr.c (transpose): Free the memory allocated to the
1016         argument, as it is replaced by the results by the unique caller.
1017         (build_relations): Merely invoke transpose: it handles the memory
1018         deallocation.
1019         Improve variable locality.
1020         Avoid variables used as mere abbreviations.
1021         (compute_lookaheads): Use arrays instead of pointers.
1022
1023 2001-12-05  Akim Demaille  <akim@epita.fr>
1024
1025         * src/lalr.c (initialize_F): Improve variable locality.
1026         Avoid variables used as mere abbreviations.
1027
1028 2001-12-05  Akim Demaille  <akim@epita.fr>
1029
1030         * src/derives.c (print_derives): Display the ruleno.
1031         * src/lalr.c (initialize_F, transpose): Better variable locality
1032         to improve readability.
1033         Avoid variables used as mere abbreviations.
1034
1035 2001-12-05  Akim Demaille  <akim@epita.fr>
1036
1037         * src/lalr.c (traverse): Use arrays instead of pointers.
1038
1039 2001-12-05  Akim Demaille  <akim@epita.fr>
1040
1041         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1042         the handling of squeue.
1043         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1044
1045 2001-12-05  Akim Demaille  <akim@epita.fr>
1046
1047         Because useless nonterminals are now kept alive (instead of being
1048         `destroyed'), we now sometimes examine them, and store information
1049         related to them.  Hence we need to know their number, and adjust
1050         memory allocations.
1051
1052         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1053         static.
1054         * src/LR0.c (allocate_itemsets): The memory allocated to
1055         `symbol_count' was used for two different purpose: once to count
1056         the number of occurrences of each symbol, and later reassigned to
1057         `shift_symbol', containing the symbol that can be shifted from a
1058         given state.
1059         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1060         only, and...
1061         (new_itemsets): Allocate `shift_symbol' here.
1062         (allocate_itemsets): symbol_count includes useless nonterminals.
1063         Make room for them.
1064         (free_storage): Use `free', not `XFREE', for pointers that cannot
1065         be null.
1066
1067 2001-12-05  Akim Demaille  <akim@epita.fr>
1068
1069         * src/nullable.c (set_nullable): Deobfuscate the handling of
1070         ritem.
1071         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1072
1073 2001-12-05  Akim Demaille  <akim@epita.fr>
1074
1075         * src/gram.c, src/gram.h (ritem_print): New.
1076         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1077         (This useless function was defined only to work around VMS linkers
1078         that can't handle compilation units with variables only).
1079         * src/reduce.c (dump_grammar): Use it to trace the construction of
1080         ritem.
1081
1082 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1083
1084         * src/bison.simple (union yyalloc): Change member names
1085         to be the same as the stack names.
1086         (yyparse): yyptr is now union yyalloc *, not char *.
1087         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1088         and may generate better code on some machines.
1089         (yystpcpy): Use prototype if __STDC__ is defined, not just
1090         if __cplusplus is defined.
1091
1092 2001-11-30  Akim Demaille  <akim@epita.fr>
1093
1094         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1095         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1096         Gettext doesn't compile cleanly, and dies with -Werror.
1097         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1098         Include WARNING_CFLAGS here.
1099         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1100         before being defined.
1101
1102 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1103
1104         * lib/quotearg.h (quotearg_n, quotearg_n_style):

1115         Name space cleanup in generated parser.
1116
1117         * doc/bison.texinfo (Bison Parser): Discuss system headers
1118         and their effect on the user name space.
1119
1120         * src/bison.simple:
1121         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1122         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1123         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1124
1125         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1126         on user names when possible.
1127
1128         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.

1147         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1148         and YYSTACK_FREE instead of malloc and free.

1164
1165 2001-11-30  Akim Demaille  <akim@epita.fr>
1166
1167         Instead of mapping the LHS of unused rules to -1, keep the LHS
1168         valid, but flag the rules as invalid.
1169

1185

1204         (union yyalloc): New type.
1205         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1206         an arbitrary restriction on hosts where size_t is wider than int.
1207
1208         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1209         a parser stack overflow.  Allocate just one block of memory for all
1210         three stacks, instead of allocating three blocks; this typically is
1211         faster and reduces fragmentation.
1212
1213         Do not limit the number of items in the stack to a value that fits
1214         in 'int', as this is an arbitrary limit on hosts with 64-bit
1215         size_t and 32-bit int.
1216
1217 2001-11-29  Marc Autret  <autret_m@epita.fr>

1271

1274
1275 2001-11-28  Akim Demaille  <akim@epita.fr>
1276
1277         * src/closure.c (closure): No longer optimize the special case
1278         where all the bits of `ruleset[r]' are set to 0, to make the code
1279         clearer.

1282

1513         * src/derives.c: Likewise.
1514         * src/reduce.c: (inaccessable_symbols): Using if is better style

1642         * tests/calc.at, tests/output.at, tests/regression.at,
1643         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
1644         now the tests are run in private dirs, therefore AC_CLEANUP and
1645         family can be simplified to 0-ary.
1646         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,

1672         arg_offset.
1673         arg is const.

1675         token_buffer not to change.

1771         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
1772         with yyltype/YYLTYPE.  This allows inclusion of the generated

2595         * src/bison.simple (yyparse): Don't take the address of an

2682         with something new. Skeletons are now processed character by character
2683         rather than line by line, and Bison looks for '%%' macros. This is the
2684         first step in making Bison's output process (a lot) more flexible.
2685         (output_parser): Use the macro table.

3013
3014         * src/reader.c (gensym): `gensym_count' is your own.
3015         Use a static buf to create the symbol name, as token_buffer is no
3016         longer a buffer.
3017
3018 2001-02-08  Akim Demaille  <akim@epita.fr>
3019
3020         * src/conflicts.c (conflict_report): Be sure not to append to res
3021         between two calls, which could happen if both first sprintf were

3027         New, from fileutils 4.0.37.
3028         * configure.in: Require Autoconf 2.49c.  I took some time before
3029         making this decision.  This is the only way out for portability
3030         issues in Bison, it would mean way too much duplicate effort to
3031         import in Bison features implemented in 2.49c since 2.13.
3032         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3042         the obstacks.
3043
3044         * src/lex.c (token_obstack): New.
3045         (init_lex): Initialize it.  No longer call...

3048

3050
3051         * src/lex.h: Rename all the tokens:
3052         s/\bENDFILE\b/tok_eof/g;
3053         s/\bIDENTIFIER\b/tok_identifier/g;
3054         etc.
3055         Let them be enums, not #define, to ease debugging.
3056         Adjust all the code.
3057
3058 2001-01-18  Akim Demaille  <akim@epita.fr>
3059
3060         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

3062
3063 2001-01-18  Akim Demaille  <akim@epita.fr>
3064
3065         Since we now use obstacks, more % directives can be enabled.
3066
3067         * src/lex.c (percent_table): Also accept `%yacc',
3068         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3069         `%debug'.
3070         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3071         instead of returning a token.
3072         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3073         * src/reader.c (read_declarations): Adjust.
3074         * src/files.c (open_files): Don't call `compute_base_names', don't
3075         compute `attrsfile' since they depend upon data which might be
3076         *in* the input file now.
3077         (output_files): Do it here.
3078         * src/output.c (output_headers): Document the fact that this patch
3079         introduces a guaranteed SEGV for semantic parsers.
3080         * doc/bison.texinfo: Document them.
3081         * tests/suite.at: Exercise these %options.
3082
3083 2000-12-20  Akim Demaille  <akim@epita.fr>
3084
3085         Also handle the output file (--verbose) with obstacks.
3086
3087         * files.c (foutput): Remove.
3088         (output_obstack): New.

3098         in the case of `-o foo.tab.c'.
3099
3100 2000-12-20  Akim Demaille  <akim@epita.fr>
3101
3102         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

3104         FILE * parameters.
3105
3106 2000-12-20  Akim Demaille  <akim@epita.fr>
3107
3108         * src/files.c (open_files): Actually the `.output' file is based
3109         on the short_base_name, not base_name.
3110         * tests/suite.at (Checking output file names): Adjust.
3111
3112 2000-12-20  Akim Demaille  <akim@epita.fr>
3113
3114         * src/bison.s1: Remove, we now use directly...

3116         * src/Makefile.am: Use pkgdata instead of data.
3117

3131         (output_files): Adjust.
3132         (base_name, short_base_name): Be global.
3133         Adjust dependencies.
3134
3135 2000-12-19  Akim Demaille  <akim@epita.fr>
3136
3137         * src/files.c (strsuffix): New.
3138         (stringappend): Be just like strcat but allocate.
3139         (base_names): Eve out from open_files.
3140         Try to simplify the rather hairy computation of base_name and
3141         short_base_name.
3142         (open_files): Use it.
3143         * tests/suite.at (Checking output file names): New test.

3152         * src/bison.hairy: Likewise.
3153
3154 2000-12-19  Akim Demaille  <akim@epita.fr>
3155
3156         * src/output.c (output_parser): Compute the `#line' lines when
3157         there are.
3158         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3159         Suggested by Hans Aberg.
3160
3161 2000-12-19  Akim Demaille  <akim@epita.fr>
3162
3163         Let the handling of the skeleton files be local to the procedures
3164         that use it.
3165
3166         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

3182
3183         * src/files.c (open_files): Yipee!  We no longer need all the code
3184         looking for `/tmp' since we have no tmp file.
3185
3186 2000-12-19  Akim Demaille  <akim@epita.fr>
3187
3188         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3201
3202         * src/reader.c (copy_definition, parse_union_decl, copy_action)
3203         (copy_guard): Quote the file names.
3204         Reported by Laurent Mascherpa.

3214
3215         * lib/obstack.h: Formatting changes.
3216         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3217         prevents type checking.
3218         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3219         cast the value to (void *): assigning a `foo *' to a `void *'
3220         variable is valid.
3221         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

3285
3286         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3302         * src/main.c (main): Don't use `atexit' to register `done', since
3303         it no longer has to remove tmp files, just call `output_files'
3304         when there are no errors.

3409         When a literal string is used to define two different tokens,
3410         `bison -v' segfaults.
3411         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3412
3413         * tests/regression.m4: New file.
3414         Include the core of the sample provided by Piotr Gackiewicz.
3415         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3416         properly.
3417
3418 2000-10-04  Akim Demaille  <akim@epita.fr>
3419
3420         * src/reader.c (parse_expect_decl): Keep `count' within the size
3421         of `buffer'.
3422         From Neil Booth.
3423
3424 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3425
3426         * bison.s1 (yyparse): Assign the default value
3427         unconditionally, to avoid a GCC warning and make the parser a
3428         tad smaller.
3429
3430 2000-10-02  Akim Demaille  <akim@epita.fr>
3431
3432         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3433         options.
3434
3435 2000-10-02  Akim Demaille  <akim@epita.fr>
3436
3437         * src/derives.c, src/print.c, src/reduce.c: To ease the
3438         translation, move some `\n' out of the translated strings.
3439
3440 2000-10-02  Akim Demaille  <akim@epita.fr>
3441
3442         The location tracking mechanism is precious for parse error
3443         messages.  Nevertheless, it is enabled only when `@n' is used in
3444         the grammar, which is a different issue (you can use it in error
3445         message, but not in the grammar per se).  Therefore, there should
3446         be another means to enable it.
3447
3448         * src/getargs.c (getargs): Support `--locations'.
3449         (usage): Report it.
3450         * src/getargs.h (locationsflag): Export it.
3451         * src/lex.c (percent_table): Support `%locations'.
3452         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3453         with `locationsflag'.
3454         * doc/bison.texinfo: Document `--locations' and `%locations'.
3455         Sort the options.
3456         * tests/calc.m4: Test it.
3457
3458         For regularity of the names, replace each
3459         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3460         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3461         In addition replace each `flag' with `_flag'.
3462
3463 2000-10-02  Akim Demaille  <akim@epita.fr>
3464
3465         Also test parse error messages, including with YYERROR_VERBOSE.
3466
3467         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3468         associative).
3469         Use it to check the computations.
3470         Use it to check `nonassoc' is honored.
3471         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3472         `--yyerror-verbose'.
3473         (_AT_CHECK_CALC): Adjust to this option.
3474         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3475
3476 2000-10-02  Akim Demaille  <akim@epita.fr>
3477
3478         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3479         the latter demonstrates a flaw in the handling of non debugging
3480         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3481         was used in order to simplify:
3482
3483         #if YYDEBUG
3484         if (yydebug)
3485         {
3486         ...
3487         }
3488         #endif
3489
3490         into
3491
3492         if (yydebug)
3493         {
3494         ...
3495         }
3496
3497         unfortunately this leads to a CPP conflict when
3498         `--name-prefix=foo' is used since it produces `#define yydebug
3499         foodebug'.
3500
3501         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3502         (YYDPRINTF): New macro.
3503         Spread its use.
3504         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3505         the bison options.
3506         Also test `--verbose', `--defines' and `--name-prefix'.
3507
3508 2000-10-02  Akim Demaille  <akim@epita.fr>
3509
3510         Improve the readability of the produced parsers.
3511
3512         * src/bison.s1: Formatting changes.
3513         Improve the comment related to the `$' mark.
3514         (yydefault): Don't fall through to `yyresume': `goto' there.
3515         * src/output.c (output_parser): When the `$' is met, skip the end
3516         of its line.
3517         New variable, `number_of_dollar_signs', to check there's exactly
3518         one `$' in the parser skeleton.
3519
3520 2000-10-02  Akim Demaille  <akim@epita.fr>
3521
3522         * lib/xstrdup.c: New file, from the fileutils.
3523         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3524         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3525         instead of strlen + xmalloc + strcpy.
3526         * src/symtab.c (copys): Remove, use xstrdup instead.
3527
3528 2000-10-02  Akim Demaille  <akim@epita.fr>
3529
3530         * src/gram.h (associativity): New enum type which replaces the
3531         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3532         `right_assoc', `left_assoc' and `non_assoc'.
3533         Adjust all dependencies.
3534         * src/reader.c: Formatting changes.
3535         (LTYPESTR): Don't define it, use it as a literal in
3536         `reader_output_yylsp'.
3537         * src/symtab.h (symbol_class): New enum type which replaces the
3538         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3539         `sunknown', `stoken and `snterm'.
3540
3541 2000-10-02  Akim Demaille  <akim@epita.fr>
3542
3543         * src/getargs.c (fixed_outfiles): Rename as...
3544         (yaccflag): for consistency and accuracy.
3545         Adjust dependencies.
3546
3547 2000-10-02  Akim Demaille  <akim@epita.fr>
3548
3549         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3550         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3551         difficult and introduced a lot of core dump.  It turns out that
3552         Bison used an implementation of `xmalloc' based on `calloc', and
3553         at various places it does depend upon the initialization to 0.  I
3554         have not tried to isolate the pertinent places, and all the former
3555         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3556         someone should address this issue.
3557
3558         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3559         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
3560         files.
3561         Adjust dependencies.
3562         * src/warshall.h: New file.
3563         Propagate.
3564
3565 2000-10-02  Akim Demaille  <akim@epita.fr>
3566
3567         Various anti-`extern in *.c' changes.
3568
3569         * src/system.h: Include `assert.h'.
3570
3571 2000-10-02  Akim Demaille  <akim@epita.fr>
3572
3573         * src/state.h (nstates, final_state, first_state, first_shift)
3574         (first_reduction): Move their exportation from here...
3575         * src/LR0.h: to here.
3576         Adjust dependencies.
3577         * src/getargs.c (statisticsflag): New variable.
3578         Add support for `--statistics'.
3579         Adjust dependencies.
3580
3581         Remove a lot of now useless `extern' statements in most files.
3582
3583 2000-10-02  Akim Demaille  <akim@epita.fr>
3584
3585         * src/LR0.h: New file.

3588 2000-10-02  Akim Demaille  <akim@epita.fr>
3589
3590         * src/print.h: New file.
3591         Propagate its use.
3592         * src/print.c: Formatting and ordering changes.
3593         (verbose, terse): Replace with...
3594         (print_results): this new function.
3595         Adjust dependencies.

3630
3631         * src/reader.h: New file.

3652
3653         * src/output.c (token_actions): Introduce a temporary array,
3654         YYDEFACT, that makes it possible for this function to use
3655         output_short_table.
3656
3657 2000-10-02  Akim Demaille  <akim@epita.fr>
3658
3659         `user_toknums' is output as a `short[]' in `output.c', while it is
3660         defined as a `int[]' in `reader.c'.  For consistency with the
3661         other output tables, `user_toknums' is now defined as a table of
3662         shorts.
3663
3664         * src/reader.c (user_toknums): Be a short table instead of an int

3677         order to get rid of the `static' prototypes.

3680         Propagate its inclusion in files explicitly prototyping functions
3681         from output.c.

3703         inclusion.
3704         Don't define PARAMS.
3705         * src/system.h: Define PARAMS.
3706         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3707         purpose of config.h.  system.h must not try to fix wrong
3708         definitions in config.h.

3897         `cplus_comment'.
3898         (copy_comment, copy_string): Moved, to be visible from
3899         copy_definition.

3925
3926         Change the handling of @s so that they behave exactly like $s.
3927         There is now a pseudo variable @$ (readble and writable), location
3928         of the lhs of the rule (by default ranging from the location of
3929         the first symbol of the rhs, to the location of the last symbol,
3930         or, if the rhs is empty, YYLLOC).

3937         same way you stack YYVAL.
3938         * src/reader.c (read_declarations): Use warns.
3939         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3940         (copy_action, case '@'): Likewise.
3941         Use a standard error message, to save useless work from
3942         translators.

3967         defined only if `YYDEBUG != 0'.
