ChangeLog

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

 365 2001-12-22  Akim Demaille  <akim@epita.fr>
 366
 367         * src/output.c (output_table_data): Change the prototype to use
 368         `int' for array ranges: some invocations do pass an int, not a
 369         short.
 370         Reported by Wayne Green.

 374         Some actions of web2c.y are improperly triggered.
 375         Reported by Mike Castle.
 376
 377         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 378         * tests/regression.at (Web2c): Rename as...
 379         (Web2c Report): this.
 380         (Web2c Actions): New.

 384         Reductions in web2c.y are improperly reported.
 385         Reported by Mike Castle.

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

 923
 924 2001-12-05  Akim Demaille  <akim@epita.fr>
 925
 926         * src/output.c (action_row): De-obfuscate
 927         using the good o' techniques: arrays not pointers, variable
 928         locality, BITISSET, RESETBIT etc.
 929
 930 2001-12-05  Akim Demaille  <akim@epita.fr>
 931
 932         Pessimize the code to simplify it: from now on, all the states
 933         have a valid SHIFTS, which NSHIFTS is possibly 0.
 934
 935         * src/LR0.c (shifts_new): Be global and move to..
 936         * src/state.c, src/state.h: here.
 937         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 938         * src/print_graph: Adjust.
 939
 940 2001-12-05  Akim Demaille  <akim@epita.fr>
 941
 942         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 943         * src/conflicts.c: Use it.
 944         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 945         incorrectly ``simplified''.
 946
 947 2001-12-05  Akim Demaille  <akim@epita.fr>
 948
 949         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
 950         using the good o' techniques: arrays not pointers, variable
 951         locality, BITISSET, RESETBIT etc.
 952
 953 2001-12-05  Akim Demaille  <akim@epita.fr>
 954
 955         * src/state.h (SHIFT_SYMBOL): New.

 957
 958 2001-12-05  Akim Demaille  <akim@epita.fr>
 959
 960         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
 961         (print_reductions): De-obfuscate using the good o' techniques:
 962         arrays not pointers, variable locality, BITISSET.
 963
 964 2001-12-05  Akim Demaille  <akim@epita.fr>
 965
 966         * src/conflicts.c (print_reductions): Arrays, not pointers.

 969 2001-12-05  Akim Demaille  <akim@epita.fr>
 970
 971         * src/conflicts.c (print_reductions): Pessimize, but clarify.

 990 2001-12-05  Akim Demaille  <akim@epita.fr>
 991
 992         * src/LR0.c (augment_automaton): Formatting changes.
 993         Better variable locality.
 994
 995 2001-12-05  Akim Demaille  <akim@epita.fr>
 996
 997         * src/lalr.c (matrix_print): New.

1000
1001 2001-12-05  Akim Demaille  <akim@epita.fr>
1002
1003         * src/lalr.c (maxrhs): Move to...
1004         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1005         * src/lalr.c (build_relations): Adjust.
1006
1007 2001-12-05  Akim Demaille  <akim@epita.fr>
1008
1009         * src/lalr.c (transpose): Free the memory allocated to the
1010         argument, as it is replaced by the results by the unique caller.
1011         (build_relations): Merely invoke transpose: it handles the memory
1012         deallocation.
1013         Improve variable locality.
1014         Avoid variables used as mere abbreviations.
1015         (compute_lookaheads): Use arrays instead of pointers.
1016
1017 2001-12-05  Akim Demaille  <akim@epita.fr>
1018
1019         * src/lalr.c (initialize_F): Improve variable locality.

1021
1022 2001-12-05  Akim Demaille  <akim@epita.fr>
1023
1024         * src/derives.c (print_derives): Display the ruleno.
1025         * src/lalr.c (initialize_F, transpose): Better variable locality
1026         to improve readability.
1027         Avoid variables used as mere abbreviations.
1028
1029 2001-12-05  Akim Demaille  <akim@epita.fr>
1030
1031         * src/lalr.c (traverse): Use arrays instead of pointers.
1032
1033 2001-12-05  Akim Demaille  <akim@epita.fr>
1034
1035         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1036         the handling of squeue.
1037         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1038
1039 2001-12-05  Akim Demaille  <akim@epita.fr>
1040
1041         Because useless nonterminals are now kept alive (instead of being
1042         `destroyed'), we now sometimes examine them, and store information
1043         related to them.  Hence we need to know their number, and adjust
1044         memory allocations.
1045
1046         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1047         static.
1048         * src/LR0.c (allocate_itemsets): The memory allocated to
1049         `symbol_count' was used for two different purpose: once to count
1050         the number of occurrences of each symbol, and later reassigned to
1051         `shift_symbol', containing the symbol that can be shifted from a
1052         given state.
1053         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1054         only, and...
1055         (new_itemsets): Allocate `shift_symbol' here.
1056         (allocate_itemsets): symbol_count includes useless nonterminals.
1057         Make room for them.
1058         (free_storage): Use `free', not `XFREE', for pointers that cannot
1059         be null.
1060
1061 2001-12-05  Akim Demaille  <akim@epita.fr>
1062
1063         * src/nullable.c (set_nullable): Deobfuscate the handling of
1064         ritem.
1065         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1066
1067 2001-12-05  Akim Demaille  <akim@epita.fr>
1068
1069         * src/gram.c, src/gram.h (ritem_print): New.
1070         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1071         (This useless function was defined only to work around VMS linkers
1072         that can't handle compilation units with variables only).
1073         * src/reduce.c (dump_grammar): Use it to trace the construction of
1074         ritem.
1075
1076 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1077
1078         * src/bison.simple (union yyalloc): Change member names
1079         to be the same as the stack names.
1080         (yyparse): yyptr is now union yyalloc *, not char *.
1081         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1082         and may generate better code on some machines.
1083         (yystpcpy): Use prototype if __STDC__ is defined, not just
1084         if __cplusplus is defined.
1085
1086 2001-11-30  Akim Demaille  <akim@epita.fr>
1087
1088         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1089         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1090         Gettext doesn't compile cleanly, and dies with -Werror.
1091         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1092         Include WARNING_CFLAGS here.
1093         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1094         before being defined.
1095
1096 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1097
1098         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1099         First arg is int, not unsigned.
1100         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1101         (SIZE_MAX, UINT_MAX): New macros.
1102         (quotearg_n_options): Abort if N is negative.
1103         Avoid overflow check on hosts where size_t is 64 bits and int
1104         is 32 bits, as overflow is impossible there.
1105         Fix off-by-one typo that caused unnecessary reallocation.

1109         Name space cleanup in generated parser.
1110
1111         * doc/bison.texinfo (Bison Parser): Discuss system headers
1112         and their effect on the user name space.
1113
1114         * src/bison.simple:
1115         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1116         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1117         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1118
1119         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1120         on user names when possible.
1121
1122         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1123         Simplify test for whather <alloca.h> exists.
1124

1141         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1142         and YYSTACK_FREE instead of malloc and free.

1160
1161         Instead of mapping the LHS of unused rules to -1, keep the LHS

1179

1198         (union yyalloc): New type.
1199         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1200         an arbitrary restriction on hosts where size_t is wider than int.
1201
1202         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1203         a parser stack overflow.  Allocate just one block of memory for all
1204         three stacks, instead of allocating three blocks; this typically is
1205         faster and reduces fragmentation.
1206
1207         Do not limit the number of items in the stack to a value that fits
1208         in 'int', as this is an arbitrary limit on hosts with 64-bit
1209         size_t and 32-bit int.
1210
1211 2001-11-29  Marc Autret  <autret_m@epita.fr>

1270
1271         * src/closure.c (closure): No longer optimize the special case
1272         where all the bits of `ruleset[r]' are set to 0, to make the code

1507         * src/derives.c: Likewise.
1508         * src/reduce.c: (inaccessable_symbols): Using if is better style

1537
1538         * src/vcg.c: You do the output, so you are responsible of the

1541         (print_actions): Don't output the actions as part of the nodes,

1636         * tests/calc.at, tests/output.at, tests/regression.at,
1637         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
1638         now the tests are run in private dirs, therefore AC_CLEANUP and
1639         family can be simplified to 0-ary.
1640         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
1641         use abs. path to find config.h.
1642         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

1666         arg_offset.
1667         arg is const.

2588
2589         * src/bison.simple (yyparse): Don't take the address of an

2599         completely wrong.

2637         (copy_string): Be a simple call to copy_string2 with the last argument
2638         bound to true.
2639         (read_declarations): Add case for macro definition.
2640         (copy_identifier): New.
2641         (parse_macro_decl): Read macro identifiers using copy_identifier

2676         with something new. Skeletons are now processed character by character
2677         rather than line by line, and Bison looks for '%%' macros. This is the
2678         first step in making Bison's output process (a lot) more flexible.
2679         (output_parser): Use the macro table.

3007
3008         * src/reader.c (gensym): `gensym_count' is your own.
3009         Use a static buf to create the symbol name, as token_buffer is no
3010         longer a buffer.

3013
3014         * src/conflicts.c (conflict_report): Be sure not to append to res
3015         between two calls, which could happen if both first sprintf were

3021         New, from fileutils 4.0.37.
3022         * configure.in: Require Autoconf 2.49c.  I took some time before
3023         making this decision.  This is the only way out for portability
3024         issues in Bison, it would mean way too much duplicate effort to
3025         import in Bison features implemented in 2.49c since 2.13.
3026         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3036         the obstacks.
3037
3038         * src/lex.c (token_obstack): New.
3039         (init_lex): Initialize it.  No longer call...

3044
3045         * src/lex.h: Rename all the tokens:
3046         s/\bENDFILE\b/tok_eof/g;
3047         s/\bIDENTIFIER\b/tok_identifier/g;
3048         etc.
3049         Let them be enums, not #define, to ease debugging.
3050         Adjust all the code.
3051
3052 2001-01-18  Akim Demaille  <akim@epita.fr>
3053
3054         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

3056
3057 2001-01-18  Akim Demaille  <akim@epita.fr>
3058
3059         Since we now use obstacks, more % directives can be enabled.
3060
3061         * src/lex.c (percent_table): Also accept `%yacc',
3062         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3063         `%debug'.
3064         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3065         instead of returning a token.
3066         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3067         * src/reader.c (read_declarations): Adjust.
3068         * src/files.c (open_files): Don't call `compute_base_names', don't
3069         compute `attrsfile' since they depend upon data which might be
3070         *in* the input file now.
3071         (output_files): Do it here.
3072         * src/output.c (output_headers): Document the fact that this patch
3073         introduces a guaranteed SEGV for semantic parsers.
3074         * doc/bison.texinfo: Document them.
3075         * tests/suite.at: Exercise these %options.
3076
3077 2000-12-20  Akim Demaille  <akim@epita.fr>
3078
3079         Also handle the output file (--verbose) with obstacks.
3080
3081         * files.c (foutput): Remove.
3082         (output_obstack): New.

3092         in the case of `-o foo.tab.c'.
3093
3094 2000-12-20  Akim Demaille  <akim@epita.fr>

3096         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

3098         FILE * parameters.
3099
3100 2000-12-20  Akim Demaille  <akim@epita.fr>
3101
3102         * src/files.c (open_files): Actually the `.output' file is based
3103         on the short_base_name, not base_name.
3104         * tests/suite.at (Checking output file names): Adjust.
3105
3106 2000-12-20  Akim Demaille  <akim@epita.fr>
3107
3108         * src/bison.s1: Remove, we now use directly...
3109         * src/bison.simple: this.
3110         * src/Makefile.am: Use pkgdata instead of data.
3111

3127         Adjust dependencies.
3128
3129 2000-12-19  Akim Demaille  <akim@epita.fr>
3130
3131         * src/files.c (strsuffix): New.
3132         (stringappend): Be just like strcat but allocate.
3133         (base_names): Eve out from open_files.
3134         Try to simplify the rather hairy computation of base_name and
3135         short_base_name.
3136         (open_files): Use it.
3137         * tests/suite.at (Checking output file names): New test.

3146         * src/bison.hairy: Likewise.
3147
3148 2000-12-19  Akim Demaille  <akim@epita.fr>
3149
3150         * src/output.c (output_parser): Compute the `#line' lines when
3151         there are.
3152         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3153         Suggested by Hans Aberg.
3154
3155 2000-12-19  Akim Demaille  <akim@epita.fr>
3156
3157         Let the handling of the skeleton files be local to the procedures
3158         that use it.
3159
3160         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

3176
3177         * src/files.c (open_files): Yipee!  We no longer need all the code
3178         looking for `/tmp' since we have no tmp file.
3179
3180 2000-12-19  Akim Demaille  <akim@epita.fr>
3181
3182         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3195
3196         * src/reader.c (copy_definition, parse_union_decl, copy_action)
3197         (copy_guard): Quote the file names.
3198         Reported by Laurent Mascherpa.

3208
3209         * lib/obstack.h: Formatting changes.
3210         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3211         prevents type checking.
3212         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3213         cast the value to (void *): assigning a `foo *' to a `void *'
3214         variable is valid.
3215         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

3298         when there are no errors.

3405         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

3410         properly.

3413
3414         * src/reader.c (parse_expect_decl): Keep `count' within the size

3418 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3419
3420         * bison.s1 (yyparse): Assign the default value
3421         unconditionally, to avoid a GCC warning and make the parser a
3422         tad smaller.
3423
3424 2000-10-02  Akim Demaille  <akim@epita.fr>
3425

3430
3431         * src/derives.c, src/print.c, src/reduce.c: To ease the

3433
3434 2000-10-02  Akim Demaille  <akim@epita.fr>
3435
3436         The location tracking mechanism is precious for parse error
3437         messages.  Nevertheless, it is enabled only when `@n' is used in
3438         the grammar, which is a different issue (you can use it in error
3439         message, but not in the grammar per se).  Therefore, there should
3440         be another means to enable it.
3441
3442         * src/getargs.c (getargs): Support `--locations'.
3443         (usage): Report it.
3444         * src/getargs.h (locationsflag): Export it.
3445         * src/lex.c (percent_table): Support `%locations'.
3446         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3447         with `locationsflag'.
3448         * doc/bison.texinfo: Document `--locations' and `%locations'.
3449         Sort the options.
3450         * tests/calc.m4: Test it.
3451
3452         For regularity of the names, replace each
3453         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3454         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3455         In addition replace each `flag' with `_flag'.
3456
3457 2000-10-02  Akim Demaille  <akim@epita.fr>
3458
3459         Also test parse error messages, including with YYERROR_VERBOSE.
3460
3461         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3462         associative).
3463         Use it to check the computations.
3464         Use it to check `nonassoc' is honored.
3465         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3466         `--yyerror-verbose'.
3467         (_AT_CHECK_CALC): Adjust to this option.
3468         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3469
3470 2000-10-02  Akim Demaille  <akim@epita.fr>
3471
3472         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3473         the latter demonstrates a flaw in the handling of non debugging
3474         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3475         was used in order to simplify:
3476
3477         #if YYDEBUG
3478         if (yydebug)
3479         {
3480         ...
3481         }
3482         #endif
3483
3484         into
3485
3486         if (yydebug)
3487         {
3488         ...
3489         }
3490
3491         unfortunately this leads to a CPP conflict when
3492         `--name-prefix=foo' is used since it produces `#define yydebug
3493         foodebug'.
3494
3495         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3496         (YYDPRINTF): New macro.
3497         Spread its use.
3498         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3499         the bison options.
3500         Also test `--verbose', `--defines' and `--name-prefix'.
3501
3502 2000-10-02  Akim Demaille  <akim@epita.fr>
3503
3504         Improve the readability of the produced parsers.
3505
3506         * src/bison.s1: Formatting changes.
3507         Improve the comment related to the `$' mark.
3508         (yydefault): Don't fall through to `yyresume': `goto' there.
3509         * src/output.c (output_parser): When the `$' is met, skip the end
3510         of its line.
3511         New variable, `number_of_dollar_signs', to check there's exactly
3512         one `$' in the parser skeleton.
3513
3514 2000-10-02  Akim Demaille  <akim@epita.fr>
3515
3516         * lib/xstrdup.c: New file, from the fileutils.
3517         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3518         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3519         instead of strlen + xmalloc + strcpy.
3520         * src/symtab.c (copys): Remove, use xstrdup instead.
3521
3522 2000-10-02  Akim Demaille  <akim@epita.fr>
3523
3524         * src/gram.h (associativity): New enum type which replaces the
3525         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3526         `right_assoc', `left_assoc' and `non_assoc'.
3527         Adjust all dependencies.
3528         * src/reader.c: Formatting changes.
3529         (LTYPESTR): Don't define it, use it as a literal in
3530         `reader_output_yylsp'.
3531         * src/symtab.h (symbol_class): New enum type which replaces the
3532         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3533         `sunknown', `stoken and `snterm'.
3534
3535 2000-10-02  Akim Demaille  <akim@epita.fr>
3536
3537         * src/getargs.c (fixed_outfiles): Rename as...
3538         (yaccflag): for consistency and accuracy.
3539         Adjust dependencies.
3540
3541 2000-10-02  Akim Demaille  <akim@epita.fr>
3542
3543         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3544         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3545         difficult and introduced a lot of core dump.  It turns out that
3546         Bison used an implementation of `xmalloc' based on `calloc', and
3547         at various places it does depend upon the initialization to 0.  I
3548         have not tried to isolate the pertinent places, and all the former
3549         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3550         someone should address this issue.
3551
3552         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3553         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
3554         files.
3555         Adjust dependencies.

3559 2000-10-02  Akim Demaille  <akim@epita.fr>
3560
3561         Various anti-`extern in *.c' changes.
3562
3563         * src/system.h: Include `assert.h'.
3564
3565 2000-10-02  Akim Demaille  <akim@epita.fr>
3566
3567         * src/state.h (nstates, final_state, first_state, first_shift)
3568         (first_reduction): Move their exportation from here...
3569         * src/LR0.h: to here.
3570         Adjust dependencies.
3571         * src/getargs.c (statisticsflag): New variable.
3572         Add support for `--statistics'.
3573         Adjust dependencies.
3574
3575         Remove a lot of now useless `extern' statements in most files.

3615
3616         * src/files.c: Formatting changes.
3617         (tryopen, tryclose, openfiles): Rename as...
3618         (xfopen, xfclose, open_files): this.
3619         (stringappend): static.
3620         * src/files.h: Complete the list of exported symbols.
3621         Propagate its use.
3622
3623 2000-10-02  Akim Demaille  <akim@epita.fr>
3624
3625         * src/reader.h: New file.
3626         Propagate its use instead of tedious list of `extern' and
3627         prototypes.
3628         * src/reader.c: Formatting changes, topological sort,
3629         s/register//.

3646
3647         * src/output.c (token_actions): Introduce a temporary array,
3648         YYDEFACT, that makes it possible for this function to use
3649         output_short_table.
3650
3651 2000-10-02  Akim Demaille  <akim@epita.fr>
3652
3653         `user_toknums' is output as a `short[]' in `output.c', while it is
3654         defined as a `int[]' in `reader.c'.  For consistency with the
3655         other output tables, `user_toknums' is now defined as a table of
3656         shorts.
3657
3658         * src/reader.c (user_toknums): Be a short table instead of an int
3659         table.
3660         Adjust dependencies.

3668 2000-10-02  Akim Demaille  <akim@epita.fr>
3669
3670         * src/output.c (output): Topological sort of the functions, in
3671         order to get rid of the `static' prototypes.
3672         No longer use `register'.
3673         * src/output.h: New file.
3674         Propagate its inclusion in files explicitly prototyping functions
3675         from output.c.

3697         inclusion.
3698         Don't define PARAMS.
3699         * src/system.h: Define PARAMS.
3700         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3701         purpose of config.h.  system.h must not try to fix wrong
3702         definitions in config.h.

3716         Use these macros to test bison with options `', `--raw',
3717         `--debug', `--yacc', `--yacc --debug'.

3780         (VERSION_STRING): Remove.

3783
3784         * src/reader.c (copy_comment2): New function, same as former

3839         * configure.in: Adjust.
3840         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

3864         the file name, not the whole `#line LINE FILE'.
3865
3866 2000-03-17  Akim Demaille  <akim@epita.fr>
3867
3868         On syntax errors, report the token on which we choked.
3869
3870         * src/bison.s1 (yyparse): In the label yyerrlab, when

3888
3889         * src/reader.c (copy_definition): Use copy_string and
3890         copy_comment.  Removed now unused `match', `ended',
3891         `cplus_comment'.
3892         (copy_comment, copy_string): Moved, to be visible from
3893         copy_definition.
3894

3896
3897         * src/reader.c (copy_string): Declare `static inline'.  No

3918 2000-03-17  Akim Demaille  <akim@epita.fr>
3919
3920         Change the handling of @s so that they behave exactly like $s.
3921         There is now a pseudo variable @$ (readble and writable), location
3922         of the lhs of the rule (by default ranging from the location of
3923         the first symbol of the rhs, to the location of the last symbol,
3924         or, if the rhs is empty, YYLLOC).
3925
3926         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3927         yyval.
3928         (yyparse): When providing a default semantic action, provide a
3929         default location action.
3930         (after the $): No longer change `*YYLSP', just stack YYLOC the
3931         same way you stack YYVAL.
3932         * src/reader.c (read_declarations): Use warns.
3933         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3934         (copy_action, case '@'): Likewise.
3935         Use a standard error message, to save useless work from
3936         translators.
3937
3938 2000-03-17  Akim Demaille  <akim@epita.fr>
3939
3940         * src/bison.s1: Formatting and cosmetics changes.

3947         Makefile now handles them.
3948
3949 2000-03-16  Akim Demaille  <akim@epita.fr>
3950

3954         Formatting changes.
3955
3956 2000-03-16  Akim Demaille  <akim@epita.fr>
3957
3958         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
3959         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3960         One `#if YYDEBUG' remains, since it uses variables which are
3961         defined only if `YYDEBUG != 0'.
3962
3963 2000-03-16  Akim Demaille  <akim@epita.fr>
3964
3965         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
