ChangeLog

   1 2001-12-29  Akim Demaille  <akim@epita.fr>
   2
   3         * src/reader.c (readgram): Don't add the rule 0 if there were no
   4         rules read.  In other words, add it _after_ having performed
   5         grammar sanity checks.
   6         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
   7
   8
   9 2001-12-29  Akim Demaille  <akim@epita.fr>
  10
  11         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
  12         visible, and some states have now a different number.
  13
  14
  15 2001-12-29  Akim Demaille  <akim@epita.fr>
  16
  17         * src/reader.c (readgram): Bind the initial rule's lineno to that
  18         of the first rule.
  19         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
  20         (Solved SR Conflicts): Adjust rule 0's line number.
  21
  22
  23 2001-12-29  Akim Demaille  <akim@epita.fr>
  24
  25         Fix the `GAWK Grammar' failure.
  26
  27         * src/LR0.c (final_state): Initialize to -1 so that we do compute
  28         the reductions of the first state which was mistakenly confused
  29         with the final state because precisely final_state was initialized
  30         to 0.
  31         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
  32         now noticed by Bison.
  33         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
  34         have a reduction on $default.
  35
  36
  37 2001-12-29  Akim Demaille  <akim@epita.fr>
  38
  39         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
  40         rule line numbers.
  41         * src/closure.c (print_closure): Likewise.
  42         * src/derives.c (print_derives): Likewise.
  43         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
  44         now.
  45
  46 2001-12-29  Akim Demaille  <akim@epita.fr>
  47
  48         * src/lalr.c (lookaheads_print): New.
  49         (lalr): Call it when --trace-flag.
  50         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
  51         are dumped.
  52
  53
  54 2001-12-29  Akim Demaille  <akim@epita.fr>
  55
  56         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
  57         when walking through ritem, even via rule->rhs.
  58         * src/reduce.c (dump_grammar, useful_production, reduce_output)
  59         (useful_production, useless_nonterminals): Likewise.
  60         (reduce_grammar_tables): Likewise, plus update nritems.
  61         * src/nullable.c (set_nullable): Likewise.
  62         * src/lalr.c (build_relations): Likewise.
  63         * tests/sets.at (Nullable): Adjust.
  64         Fortunately, now, the $axiom is no longer nullable.
  65
  66
  67 2001-12-29  Akim Demaille  <akim@epita.fr>
  68
  69         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
  70         the 0-sentinel.
  71         * src/gram.c (ritem_longest_rhs): Likewise.
  72         * src/reduce.c (nonterminals_reduce): Likewise.
  73         * src/print_graph.c (print_graph): Likewise.
  74         * src/output.c (output_rule_data): Likewise.
  75         * src/nullable.c (set_nullable):  Likewise.
  76
  77 2001-12-29  Akim Demaille  <akim@epita.fr>
  78
  79         * src/output.c: Comment changes.
  80
  81 2001-12-27  Paul Eggert  <eggert@twinsun.com>
  82
  83         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
  84         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
  85         Sparc, as they were causing more porting problems than the
  86         (minor) performance improvement was worth.
  87
  88         Also, catch up with 1.31's YYSTD.
  89
  90 2001-12-27  Akim Demaille  <akim@epita.fr>
  91
  92         * src/output.c (output_gram): Rely on nritems, not the
  93         0-sentinel.  See below.
  94         Use -1 as separator, not 0.
  95         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
  96         Rely on -1 as separator in yyrhs, instead of 0.
  97         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
  98         twice `Now at end of input', therefore there are two lines less to
  99         expect.
 100
 101 2001-12-27  Akim Demaille  <akim@epita.fr>
 102
 103         * tests/regression.at (Unresolved SR Conflicts):
 104         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 105         below.
 106
 107 2001-12-27  Akim Demaille  <akim@epita.fr>
 108
 109         * src/LR0.c (new_state): Recognize the final state by the fact it
 110         is reached by eoftoken.
 111         (insert_start_shifting_state, insert_eof_shifting_state)
 112         (insert_accepting_state, augment_automaton): Remove, since now
 113         these states are automatically computed from the initial state.
 114         (generate_states): Adjust.
 115         * src/print.c: When reporting a rule number to the user, substract
 116         1, so that the axiom rule is rule 0, and the first user rule is 1.
 117         * src/reduce.c: Likewise.
 118         * src/print_graph.c (print_core): For the time being, just as for
 119         the report, depend upon --trace-flags to dump the full set of
 120         items.
 121         * src/reader.c (readgram): Once the grammar read, insert the rule
 122         0: `$axiom: START-SYMBOL $'.
 123         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 124         number of the states has changed (the final state is no longer
 125         necessarily the last), catch up.
 126
 127 2001-12-27  Akim Demaille  <akim@epita.fr>
 128
 129         Try to make the use of the eoftoken valid.  Given that its value
 130         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 131         is used instead of > 0 where appropriate, (ii), depend upon nritems
 132         instead of the 0-sentinel.
 133
 134         * src/gram.h, src/gram.c (nritems): New.
 135         Expected to be duplication of nitems, but for the time being...
 136         * src/reader.c (packgram): Assert nritems and nitems are equal.
 137         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 138         * src/closure.c (print_closure, print_fderives): Likewise.
 139         * src/gram.c (ritem_print): Likewise.
 140         * src/print.c (print_core, print_grammar): Likewise.
 141         * src/print_graph.c: Likewise.
 142
 143 2001-12-27  Akim Demaille  <akim@epita.fr>
 144
 145         * src/main.c (main): If there are complains after grammar
 146         reductions, then output the report anyway if requested, then die.
 147         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 148         * src/reader.c (eoftoken): New.
 149         (parse_token_decl): If the token being defined has value `0', it
 150         is the eoftoken.
 151         (packsymbols): No longer hack `tags' to insert `$' by hand.
 152         Be sure to preserve the value of the eoftoken.
 153         (reader): Make sure eoftoken is defined.
 154         Initialize nsyms to 0: now eoftoken is created just like the others.
 155         * src/print.c (print_grammar): Don't special case the eof token.
 156         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 157         lie anyway, albeit pleasant.
 158         * tests/calc.at: Exercise error messages with eoftoken.
 159         Change the grammar so that empty input is invalid.
 160         Adjust expectations.
 161         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 162
 163 2001-12-27  Akim Demaille  <akim@epita.fr>
 164
 165         * configure.in: Check the protos of strchr ans strspn.
 166         Replace strchr if needed.
 167         * src/system.h: Provide the protos of strchr, strspn and memchr if
 168         missing.
 169         * lib/strchr.c: New.
 170         * src/reader.c (symbols_save): Use strchr.
 171
 172 2001-12-27  Akim Demaille  <akim@epita.fr>
 173
 174         * src/print.c, src/print_graph.c (escape): New.
 175         Use it to quote the TAGS outputs.
 176         * src/print_graph.c (print_state): Now errors are in red, and
 177         reductions in green.
 178         Prefer high to wide: output the state number on a line of its own.
 179
 180 2001-12-27  Akim Demaille  <akim@epita.fr>
 181
 182         * src/state.h, src/state.c (reductions_new): New.
 183         * src/LR0.c (set_state_table): Let all the states have a
 184         `reductions', even if reduced to 0.
 185         (save_reductions): Adjust.
 186         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 187         * src/print.c (print_reductions, print_actions): Adjust.
 188         * src/output.c (action_row): Adjust.
 189
 190 2001-12-27  Akim Demaille  <akim@epita.fr>
 191
 192         * src/state.h, src/state.c (errs_new, errs_dup): New.
 193         * src/LR0.c (set_state_table): Let all the states have an errs,
 194         even if reduced to 0.
 195         * src/print.c (print_errs, print_reductions): Adjust.
 196         * src/output.c (output_actions, action_row): Adjust.
 197         * src/conflicts.c (resolve_sr_conflict): Adjust.
 198
 199 2001-12-27  Akim Demaille  <akim@epita.fr>
 200
 201         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 202
 203 2001-12-27  Akim Demaille  <akim@epita.fr>
 204
 205         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 206         * src/print.c: here.
 207         (lookaheadset, shiftset): New, used as additional storage by
 208         print_reductions.
 209         (print_results): Adjust.
 210         (print_shifts, print_gotos, print_errs): New, extracted from...
 211         (print_actions): here.
 212         * src/print_graph.c (print_actions): Remove dead code.
 213
 214 2001-12-27  Akim Demaille  <akim@epita.fr>
 215
 216         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 217         `$n' and `@n'.
 218
 219 2001-12-27  Akim Demaille  <akim@epita.fr>
 220
 221         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 222         (build_relations): Adjust.
 223
 224 2001-12-27  Akim Demaille  <akim@epita.fr>
 225
 226         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 227         duplication.
 228
 229 2001-12-27  Akim Demaille  <akim@epita.fr>
 230
 231         * src/reader.c (packgram): Catch nitems overflows.
 232
 233 2001-12-27  Akim Demaille  <akim@epita.fr>
 234
 235         * src/files.c, src/files.h (guard_obstack): Remove.
 236         * src/output.c (output): Adjust.
 237         * src/reader.c (parse_braces): New, factoring...
 238         (copy_action, copy_guard): these two which are renamed as...
 239         (parse_action, parse_guard): these.
 240         As a voluntary consequence, using braces around guards is now
 241         mandatory.
 242
 243 2001-12-27  Akim Demaille  <akim@epita.fr>
 244
 245         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 246         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 247         members.
 248         (symbol_list_new): Adjust.
 249         (copy_action): action_line is the first line, not the last.
 250         (copy_guard): Just as for actions, store the `action' only, not
 251         the switch/case/break flesh.
 252         Don't parse the user action that might follow the guard, let...
 253         (readgram): do it, i.e., now, there can be an action after a
 254         guard.
 255         In other words the guard is just explicitly optional.
 256         (packgram): Adjust.
 257         * src/output.c (guards_output): New.
 258         (output_parser): Call it when needed.
 259         (output): Also free the guard and attrs obstacks.
 260         * src/files.c, src/files.h (obstack_save): Remove.
 261         (output_files): Remove.
 262         As a result, if one needs the former `.act' file, using an
 263         appropriate skeleton which requires actions and guards is now
 264         required.
 265         * src/main.c (main): Adjust.
 266         * tests/semantic.at: New.
 267         * tests/regression.at: Use `input.y' as input file name.
 268         Avoid 8+3 problems by requiring input.c when the test needs the
 269         parser.
 270
 271 2001-12-27  Akim Demaille  <akim@epita.fr>
 272
 273         * src/reader.c (symbol_list_new): Be sure to initialize all the
 274         fields.
 275
 276 2001-12-27  Akim Demaille  <akim@epita.fr>
 277
 278         All the hacks using a final pseudo state are now useless.
 279
 280         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 281         * src/lalr.c (nLA): New.
 282         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 283         instead of lookaheadsp from the pseudo state (nstate + 1).
 284
 285 2001-12-27  Akim Demaille  <akim@epita.fr>
 286
 287         * src/output.c (action_row, token_actions): Use a state_t instead
 288         of a integer, and nlookaheads instead of the following state's
 289         lookaheadsp.
 290
 291 2001-12-27  Akim Demaille  <akim@epita.fr>
 292
 293         * src/conflicts.c (log_resolution, flush_shift)
 294         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 295         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 296         (conflicts_print, print_reductions): Use a state_t instead of an
 297         integer when referring to a state.
 298         As much as possible, depend upon nlookaheads, instead of the
 299         `lookaheadsp' member of the following state (since lookaheads of
 300         successive states are successive, the difference between state n + 1
 301         and n served as the number of lookaheads for state n).
 302         * src/lalr.c (add_lookback_edge): Likewise.
 303         * src/print.c (print_core, print_actions, print_state)
 304         (print_results): Likewise.
 305         * src/print_graph.c (print_core, print_actions, print_state)
 306         (print_graph): Likewise.
 307         * src/conflicts.h: Adjust.
 308
 309 2001-12-27  Akim Demaille  <akim@epita.fr>
 310
 311         * src/bison.hairy: Formatting/comment changes.
 312         ANSIfy.
 313         Remove `register' indications.
 314         Add plenty of `static'.
 315
 316 2001-12-27  Akim Demaille  <akim@epita.fr>
 317
 318         * src/output.c (prepare): Drop the muscle `ntbase' which
 319         duplicates ntokens.
 320         * src/bison.simple: Formatting/comment changes.
 321         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 322         is an undocumented synonym.
 323
 324 2001-12-22  Akim Demaille  <akim@epita.fr>
 325
 326         * src/output.c (output_table_data): Change the prototype to use
 327         `int' for array ranges: some invocations do pass an int, not a
 328         short.
 329         Reported by Wayne Green.
 330
 331 2001-12-22  Akim Demaille  <akim@epita.fr>
 332
 333         Some actions of web2c.y are improperly triggered.
 334         Reported by Mike Castle.
 335
 336         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 337         * tests/regression.at (Web2c): Rename as...
 338         (Web2c Report): this.
 339         (Web2c Actions): New.
 340
 341 2001-12-22  Akim Demaille  <akim@epita.fr>
 342
 343         Reductions in web2c.y are improperly reported.
 344         Reported by Mike Castle.
 345
 346         * src/conflicts.c (print_reductions): Fix.
 347         * tests/regression.at (Web2c): New.
 348
 349 2001-12-18  Akim Demaille  <akim@epita.fr>
 350
 351         Some host fail on `assert (!"foo")', which expands to
 352         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 353         Reported by Nelson Beebee.
 354
 355         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 356         `#define it_succeeded 0' and `assert (it_succeeded)'.

 360         * src/bison.simple: Don't hard code the skeleton line and filename.
 361         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 362         New line counter 'skeleton_line' (skeleton-line muscle).
 363
 364 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 365
 366         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 367         YYDEBUG must be defined to a nonzero value.
 368
 369         * src/bison.simple (yytname): Do not assume that the user defines
 370         YYDEBUG to a properly parenthesized expression.
 371
 372 2001-12-17  Akim Demaille  <akim@epita.fr>
 373
 374         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 375         nlookaheads is a new member.
 376         Adjust all users.
 377         * src/lalr.h (nlookaheads): Remove this orphan declaration.
 378         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 379         state.
 380
 381 2001-12-17  Akim Demaille  <akim@epita.fr>
 382
 383         * src/files.h, src/files.c (open_files, close_files): Remove.
 384         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 385         let...
 386         * src/reader.c (reader): Do it.
 387
 388 2001-12-17  Akim Demaille  <akim@epita.fr>
 389
 390         * src/conflicts.c (print_reductions): Formatting changes.
 391
 392 2001-12-17  Akim Demaille  <akim@epita.fr>
 393
 394         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 395         (flush_reduce): New.
 396         (resolve_sr_conflict): Adjust.
 397
 398 2001-12-17  Akim Demaille  <akim@epita.fr>
 399
 400         * src/output.c (output_obstack): Be static and rename as...
 401         (format_obstack): this, to avoid any confusion with files.c's
 402         output_obstack.
 403         * src/reader.h (muscle_obstack): Move to...
 404         * src/output.h: here, since it's defined in output.c.
 405
 406 2001-12-17  Akim Demaille  <akim@epita.fr>
 407
 408         * src/output.c (action_row, save_column, default_goto)
 409         (sort_actions, matching_state, pack_vector): Better variable
 410         locality.
 411
 412 2001-12-17  Akim Demaille  <akim@epita.fr>
 413
 414         * src/output.c: Various formatting changes.
 415
 416 2001-12-17  Akim Demaille  <akim@epita.fr>
 417
 418         * src/files.c (output_files): Free the output_obstack.
 419         * src/main.c (main): Call print and print_graph conditionally.
 420         * src/print.c (print): Work unconditionally.
 421         * src/print_graph.c (print_graph): Work unconditionally.
 422         * src/conflicts.c (log_resolution): Output only if verbose_flag.
 423
 424 2001-12-16  Marc Autret  <autret_m@epita.fr>
 425
 426         * src/output.c (actions_output): Fix. When we use %no-lines,
 427         there is one less line per action.
 428
 429 2001-12-16  Marc Autret  <autret_m@epita.fr>
 430
 431         * src/bison.simple: Remove a useless #line directive.
 432         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 433         * src/output.c (get_lines_number): New.
 434         (output_parser): Adjust, now takes care about the lines of a
 435         output muscles.
 436         Fix line numbering.
 437         (actions_output): Computes the number of lines taken by actions.
 438         (output_master_parser): Insert new skeleton which is the name of
 439         the output parser file name.
 440
 441 2001-12-15  Marc Autret  <autret_m@epita.fr>
 442
 443         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
 444
 445 2001-12-15  Marc Autret  <autret_m@epita.fr>
 446
 447         * src/output.c (output_gram): Keep track of the hairy one.
 448
 449 2001-12-15  Akim Demaille  <akim@epita.fr>
 450
 451         Make `make distcheck' work.
 452
 453         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 454         system.h which uses libgettext.h.
 455
 456 2001-12-15  Akim Demaille  <akim@epita.fr>
 457
 458         * src/nullable.c (set_nullable): Useless rules must be skipped,
 459         otherwise, since we range over their symbols, we might look at a
 460         nonterminal which no longer ``exists'', i.e., it is not counted in
 461         `nvars', hence we overflow our arrays.
 462
 463 2001-12-15  Akim Demaille  <akim@epita.fr>
 464
 465         The header can also be produced directly, without any obstack!
 466         Yahoo!
 467
 468         * src/files.c, src/files.h (defines_obstack): Remove.
 469         (compute_header_macro): Global.
 470         (defines_obstack_save): Remove.
 471         * src/reader.c (parse_union_decl): No longer output to
 472         defines_obstack: its content can be found in the `stype' muscle
 473         anyway.
 474         (output_token_translations): Merge into...
 475         (symbols_output): this.
 476         Rename as...
 477         (symbols_save): this.
 478         (reader): Adjust.
 479         * src/output.c (header_output): New.
 480         (output): Call it.
 481
 482 2001-12-15  Akim Demaille  <akim@epita.fr>
 483
 484         * src/reader.c (parse_union_decl): Instead of handling two obstack
 485         simultaneously, use one to define the `stype' muscle, and use the
 486         value of the latter to fill defines_obstack.
 487         (copy_comment): Remove.
 488         (copy_comment2): Work for a single obstack.
 489         Rename as...
 490         (copy_comment): this.
 491
 492 2001-12-15  Akim Demaille  <akim@epita.fr>
 493
 494         * src/lex.c, src/lex.h (xgetc): No longer static.
 495         * src/reader.c (parse_union_decl): Revamp.
 496
 497 2001-12-15  Akim Demaille  <akim@epita.fr>
 498
 499         Still making progress in separating Bison into (i) input, (ii)
 500         process, (iii) output: now we can directly output the parser file
 501         without using table_obstack at all.
 502
 503         * src/files.c, src/files.h (table_obstack): Bye bye.
 504         (parser_file_name): New.
 505         * src/files.c (compute_output_file_names): Compute it.
 506         * src/output.c (actions_output, output_parser)
 507         (output_master_parser): To a file instead of an obstack.
 508
 509 2001-12-15  Akim Demaille  <akim@epita.fr>
 510
 511         Attach actions to rules, instead of pre-outputting them to
 512         actions_obstack.
 513
 514         * src/gram.h (rule_t): action and action_line are new members.
 515         * src/reader.c (symbol_list): Likewise.
 516         (copy_action): Save the actions within the rule.
 517         (packgram): Save them in rule_table.
 518         * src/output.c (actions_output): New.
 519         (output_parser): Use it on `%%actions'.
 520         (output_rule_data): Don't free rule_table.
 521         (output): Do it.
 522         (prepare): Don't save the `action' muscle.
 523         * src/bison.simple: s/%%action/%%actions/.
 524
 525 2001-12-15  Akim Demaille  <akim@epita.fr>
 526
 527         * src/reader.c (copy_action): When --yacc, don't append a `;'
 528         to the user action: let it fail if lacking.
 529         Suggested by Arnold Robbins and Tom Tromey.
 530
 531 2001-12-14  Akim Demaille  <akim@epita.fr>
 532
 533         * src/lex.c (literalchar): Simply return the char you decoded, non
 534         longer mess around with obstacks and int pointers.
 535         Adjust all callers.
 536
 537 2001-12-14  Akim Demaille  <akim@epita.fr>
 538
 539         * src/lex.c (literalchar): Don't escape the special characters,
 540         just decode them, and keep them as char (before, eol was output as
 541         the 2 char string `\n' etc.).
 542         * src/output.c (output_rule_data): Use quotearg to output the
 543         token strings.
 544
 545 2001-12-13  Paul Eggert  <eggert@twinsun.com>
 546
 547         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
 548         Do not infringe on the global user namespace when using C++.
 549         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
 550         All uses of `fprintf' and `stderr' changed.
 551
 552         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
 553
 554 2001-12-13  Akim Demaille  <akim@epita.fr>
 555
 556         The computation of nullable is broken: it doesn't handle empty
 557         RHS's properly.
 558
 559         * tests/torture.at (GNU AWK Grammar): New.
 560         * tests/sets.at (Nullable): New.
 561         * src/nullable.c (set_nullable): Instead of blindly looping over
 562         `ritems', loop over the rules, and then over their rhs's.
 563
 564         Work around Autotest bugs.
 565
 566         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
 567         frame, because Autotest understand lines starting with a `+' as
 568         traces from the shell.  Then, they are not processed properly.
 569         Admittedly an Autotest bug, but we don't have time to wait for
 570         Autotest to catch up.
 571         * tests/regression.at (Broken Closure): Adjust to the new table
 572         frames.
 573         Move to...
 574         * tests/sets.at: here.
 575
 576 2001-12-13  Akim Demaille  <akim@epita.fr>
 577
 578         * src/closure.c (closure): Use nrules instead of playing tricks
 579         with BITS_PER_WORD.
 580
 581 2001-12-13  Akim Demaille  <akim@epita.fr>
 582
 583         * src/print.c (print_actions): Output the handling of `$' as the
 584         traces do: shifting the token EOF.  Before EOF was treated as a
 585         nonterminal.
 586         * tests/regression.at: Adjust some tests.
 587         * src/print_graph.c (print_core): Complete the set of items via
 588         closure.  The next-to-final and final states are still unsatisfying,
 589         but that's to be addressed elsewhere.
 590         No longer output the rule numbers, but do output the state number.
 591         A single loop for the shifts + gotos is enough, but picked a
 592         distinct color for each.
 593         (print_graph): Initialize and finalize closure.
 594
 595 2001-12-13  Akim Demaille  <akim@epita.fr>
 596
 597         * src/reader.c (readgram): Remove dead code, an strip useless
 598         braces.
 599         (get_type): Remove, unused.
 600
 601 2001-12-12  Akim Demaille  <akim@epita.fr>
 602
 603         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 604         on that of lib/error.c.
 605
 606 2001-12-12  Akim Demaille  <akim@epita.fr>
 607
 608         Some hosts don't like `/' in includes.
 609
 610         * src/system.h: Include libgettext.h without qualifying the path.
 611         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 612         $(top_srcdir).
 613
 614 2001-12-11  Marc Autret  <autret_m@epita.fr>
 615
 616         * src/output.c (output_parser): Remove useless muscle.
 617
 618 2001-12-11  Marc Autret  <autret_m@epita.fr>
 619
 620         * src/bison.simple: Remove #line just before %%epilogue. It
 621         is now handled in ...
 622         * src/reader.c (read_additionnal_code): Add the output of a
 623         #line for the epilogue.
 624
 625 2001-12-10  Marc Autret  <autret_m@epita.fr>
 626
 627         * src/reader.c (copy_definition): Re-use CPP-outed code which
 628         replace precedent remove.
 629         * src/bison.simple: Remove #line before %%prologue because
 630         %%input-line is wrong at this time.
 631
 632 2001-12-10  Marc Autret  <autret_m@epita.fr>
 633
 634         * src/reader.c (symbols_output): Clean up.
 635         * src/output.c (output_gram, output): Clean up.
 636
 637 2001-12-10  Akim Demaille  <akim@epita.fr>
 638
 639         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 640         * src/LR0.c (set_state_table): here.
 641         * src/lalr.c (lalr): Call it.
 642
 643 2001-12-10  Akim Demaille  <akim@epita.fr>
 644
 645         * src/state.h (shifts): Remove the `number' member: shifts are
 646         attached to state, hence no longer need to be labelled with a
 647         state number.
 648
 649 2001-12-10  Akim Demaille  <akim@epita.fr>
 650
 651         Now that states have a complete set of members, the linked list of
 652         shifts is useless: just fill directly the state's shifts member.
 653
 654         * src/state.h (shifts): Remove the `next' member.
 655         * src/LR0.c (first_state, last_state): Remove.
 656         Adjust the callers.
 657         (augment_automaton): Don't look for the shifts that must be added
 658         a shift on EOF: it is those of the state we looked for!  But now,
 659         since shifts are attached, it is no longer needed to looking
 660         merely by its id: its number.
 661
 662 2001-12-10  Akim Demaille  <akim@epita.fr>
 663
 664         * src/LR0.c (augment_automaton): Better variable locality.
 665         Remove an impossible branch: if there is a state corresponding to
 666         the start symbol being shifted, then there is shift for the start
 667         symbol from the initial state.
 668
 669 2001-12-10  Akim Demaille  <akim@epita.fr>
 670
 671         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 672         only when appropriate: when insert_start_shifting_state' is not
 673         invoked.
 674         * tests/regression.at (Rule Line Numbers): Adjust.
 675
 676 2001-12-10  Akim Demaille  <akim@epita.fr>
 677
 678         * src/LR0.c (augment_automaton): Now that all states have shifts,
 679         merge the two cases addition shifts to the initial state.
 680
 681 2001-12-10  Akim Demaille  <akim@epita.fr>
 682
 683         * src/lalr.c (set_state_table): Move to...
 684         * src/LR0.c: here.
 685         * src/lalr.c (lalr): Don't call it...
 686         * src/LR0.c (generate_states): do it.
 687         * src/LR0.h (first_state): Remove, only the table is used.
 688
 689 2001-12-10  Akim Demaille  <akim@epita.fr>
 690
 691         * src/LR0.h (first_shift, first_reduction): Remove.
 692         * src/lalr.c: Don't use first_shift: find shifts through the
 693         states.
 694
 695 2001-12-10  Akim Demaille  <akim@epita.fr>
 696
 697         * src/LR0.c: Attach shifts to states as soon as they are
 698         computed.
 699         * src/lalr.c (set_state_table): Instead of assigning shifts to
 700         state, just assert that the mapping was properly done.
 701
 702 2001-12-10  Akim Demaille  <akim@epita.fr>
 703
 704         * src/LR0.c (insert_start_shift): Rename as...
 705         (insert_start_shifting_state): this.
 706         (insert_eof_shifting_state, insert_accepting_state): New.
 707         (augment_automaton): Adjust.
 708         Better locality of the variables.
 709         When looking if the start_symbol is shifted from the initial
 710         state, using `while (... symbol != start_symbol ...)' sounds
 711         better than `while (... symbol < start_symbol ...)': If fail
 712         to see how the order between symbols could be relevant!
 713
 714 2001-12-10  Akim Demaille  <akim@epita.fr>
 715
 716         * src/getargs.h: Don't declare `spec_name_prefix' and
 717         `spec_file_prefix', declared by src/files.h.
 718         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 719         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 720         * src/output.c (prepare): Adjust.
 721         * src/reader.c (symbols_output): Likewise.
 722         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 723
 724 2001-12-10  Akim Demaille  <akim@epita.fr>
 725
 726         * src/muscle_tab.c (muscle_init): NULL is a better default than
 727         `"0"'.
 728
 729 2001-12-10  Akim Demaille  <akim@epita.fr>
 730
 731         * src/reader.c (reader): Calling symbols_output once is enough.
 732
 733 2001-12-10  Akim Demaille  <akim@epita.fr>
 734
 735         Now that states have a complete set of members, the linked list of
 736         reductions is useless: just fill directly the state's reductions
 737         member.
 738
 739         * src/state.h (struct reductions): Remove member `number' and
 740         `next'.
 741         * src/LR0.c (first_reduction, last_reduction): Remove.
 742         (save_reductions): Don't link the new reductions, store them in
 743         this_state.
 744         * src/lalr.c (set_state_table): No need to attach reductions to
 745         states, it's already done.
 746         * src/output.c (output_actions): No longer free the shifts, then
 747         the reductions, then the states: free all the states and their
 748         members.
 749
 750 2001-12-10  Akim Demaille  <akim@epita.fr>
 751
 752         * src/options.c (OPTN, DRTV, BOTH): New.
 753         (option_table): Use them.
 754
 755         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 756         the job of system.h.
 757         * src/options.c: Don't include stdio.h and xalloc.h for the same
 758         reasons.
 759
 760 2001-12-10  Akim Demaille  <akim@epita.fr>
 761
 762         * src/output.c (output, prepare): Make sure the values of the
 763         muscles `action' and `prologue' are 0-terminated.
 764
 765 2001-12-10  Akim Demaille  <akim@epita.fr>
 766
 767         Clean up GCC warnings.
 768
 769         * src/reader.c (copy_action): `buf' is not used.
 770         (parse_skel_decl): Be static.
 771         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 772         * src/options.h (create_long_option_table): Have a real prototype.
 773         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 774         (hash_delete_at): Return const void *.
 775         Adjust casts to preserve the const.
 776
 777 2001-12-10  Akim Demaille  <akim@epita.fr>
 778
 779         * configure.in: Require 2.52g.
 780         M4 is not needed, but AUTOM4TE is.
 781         * m4/m4.m4: Remove.
 782         * tests/Makefile.am: Adjust.
 783
 784 2001-12-10  Akim Demaille  <akim@epita.fr>
 785
 786         One structure for states is enough, even though theoretically
 787         there are LR(0) states and LALR(1) states.
 788
 789         * src/lalr.h (state_t): Remove.
 790         (state_table): Be state_t **, not state_t *.
 791         * src/state.h (core, CORE_ALLOC): Rename as...
 792         (state_t, STATE_ALLOC): this.
 793         Add the LALR(1) members: shifts, reductions, errs.
 794         * src/LR0.c (state_table): Rename as...
 795         (state_hash): this, to avoid name clashes with the global
 796         `state_table'.
 797         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 798         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 799
 800 2001-12-10  Akim Demaille  <akim@epita.fr>
 801
 802         Bison dumps core on bash.y.
 803         Reported by Pascal Bart.
 804
 805         * src/warshall.c (bitmatrix_print): New.
 806         (TC): Use it.
 807         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 808         j must be the outer loop.
 809         * tests/regression.at (Broken Closure): New.
 810
 811 2001-12-05  Akim Demaille  <akim@epita.fr>
 812
 813         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 814         its argument.
 815         Reported by Peter Hámorský.
 816
 817 2001-12-05  Akim Demaille  <akim@epita.fr>
 818
 819         * src/conflicts.c (err_table): Remove.
 820         (resolve_sr_conflict): Adjust.
 821         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 822         Rename as...
 823         (state_t.reductions, state_t.shifts): this.
 824
 825 2001-12-05  Akim Demaille  <akim@epita.fr>
 826
 827         * src/reduce.c (reduce_grammar_tables): No longer disable the
 828         removal of useless rules via CPP but via `if (0)', so that the
 829         compiler still check the code is valid.
 830         For instance, it should have noticed `rline' no longer exists: use
 831         the `line' member of rule_t.
 832         * src/gram.c (dummy, rline): Remove, unused.
 833
 834 2001-12-05  Akim Demaille  <akim@epita.fr>
 835
 836         * src/output.c (pack_vector): Use assert, not berror.
 837         * src/main.c (berror): Remove, unused.
 838
 839 2001-12-05  Akim Demaille  <akim@epita.fr>
 840
 841         New experimental feature: if --verbose --trace output all the
 842         items of a state, not only its kernel.
 843
 844         * src/print.c (print_core): If `trace_flag', then invoke closure
 845         before outputting the items of the state (print_core is no longer
 846         a correct name them).
 847         (print_results): Invoke new_closure/free_closure if needed.
 848
 849 2001-12-05  Akim Demaille  <akim@epita.fr>
 850
 851         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 852         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 853         (nitemset): for consistency with the rest of the project.
 854
 855 2001-12-05  Akim Demaille  <akim@epita.fr>
 856
 857         * src/closure.c (print_closure): Improve.
 858         (closure): Use it for printing input and output.
 859
 860 2001-12-05  Akim Demaille  <akim@epita.fr>
 861
 862         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 863         indexed by nonterminals.
 864
 865 2001-12-05  Akim Demaille  <akim@epita.fr>
 866
 867         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 868         what it was!).
 869         * src/warshall.h: Remove accidental duplication of the content.
 870
 871 2001-12-05  Akim Demaille  <akim@epita.fr>
 872
 873         * src/closure.c (set_fderives): De-obfuscate.
 874
 875 2001-12-05  Akim Demaille  <akim@epita.fr>
 876
 877         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
 878
 879 2001-12-05  Akim Demaille  <akim@epita.fr>
 880
 881         * src/closure.c (set_firsts): De-obfuscate.
 882
 883 2001-12-05  Akim Demaille  <akim@epita.fr>
 884
 885         * src/output.c (action_row): De-obfuscate
 886         using the good o' techniques: arrays not pointers, variable
 887         locality, BITISSET, RESETBIT etc.
 888
 889 2001-12-05  Akim Demaille  <akim@epita.fr>
 890
 891         Pessimize the code to simplify it: from now on, all the states
 892         have a valid SHIFTS, which NSHIFTS is possibly 0.
 893
 894         * src/LR0.c (shifts_new): Be global and move to..
 895         * src/state.c, src/state.h: here.
 896         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 897         * src/print_graph: Adjust.
 898
 899 2001-12-05  Akim Demaille  <akim@epita.fr>
 900
 901         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 902         * src/conflicts.c: Use it.
 903         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 904         incorrectly ``simplified''.
 905
 906 2001-12-05  Akim Demaille  <akim@epita.fr>
 907
 908         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
 909         using the good o' techniques: arrays not pointers, variable
 910         locality, BITISSET, RESETBIT etc.
 911
 912 2001-12-05  Akim Demaille  <akim@epita.fr>
 913
 914         * src/state.h (SHIFT_SYMBOL): New.
 915         * src/conflicts.c: Use it to deobfuscate.
 916
 917 2001-12-05  Akim Demaille  <akim@epita.fr>
 918
 919         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
 920         (print_reductions): De-obfuscate using the good o' techniques:
 921         arrays not pointers, variable locality, BITISSET.
 922
 923 2001-12-05  Akim Demaille  <akim@epita.fr>
 924
 925         * src/conflicts.c (print_reductions): Arrays, not pointers.
 926         Use BITISSET.
 927
 928 2001-12-05  Akim Demaille  <akim@epita.fr>
 929
 930         * src/conflicts.c (print_reductions): Pessimize, but clarify.
 931
 932 2001-12-05  Akim Demaille  <akim@epita.fr>
 933
 934         * src/conflicts.c (print_reductions): Improve variable locality.
 935
 936 2001-12-05  Akim Demaille  <akim@epita.fr>
 937
 938         * src/conflicts.c (print_reductions): Pessimize, but clarify.

 940 2001-12-05  Akim Demaille  <akim@epita.fr>
 941

 945
 946         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
 947         * src/lalr.c: Use them.
 948
 949 2001-12-05  Akim Demaille  <akim@epita.fr>
 950
 951         * src/LR0.c (augment_automaton): Formatting changes.
 952         Better variable locality.
 953
 954 2001-12-05  Akim Demaille  <akim@epita.fr>
 955
 956         * src/lalr.c (matrix_print): New.
 957         (transpose): Use it.
 958         Use arrays instead of pointers.
 959
 960 2001-12-05  Akim Demaille  <akim@epita.fr>
 961
 962         * src/lalr.c (maxrhs): Move to...
 963         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
 964         * src/lalr.c (build_relations): Adjust.
 965
 966 2001-12-05  Akim Demaille  <akim@epita.fr>
 967
 968         * src/lalr.c (transpose): Free the memory allocated to the
 969         argument, as it is replaced by the results by the unique caller.
 970         (build_relations): Merely invoke transpose: it handles the memory
 971         deallocation.
 972         Improve variable locality.
 973         Avoid variables used as mere abbreviations.
 974         (compute_lookaheads): Use arrays instead of pointers.
 975
 976 2001-12-05  Akim Demaille  <akim@epita.fr>
 977
 978         * src/lalr.c (initialize_F): Improve variable locality.
 979         Avoid variables used as mere abbreviations.
 980
 981 2001-12-05  Akim Demaille  <akim@epita.fr>
 982
 983         * src/derives.c (print_derives): Display the ruleno.
 984         * src/lalr.c (initialize_F, transpose): Better variable locality
 985         to improve readability.
 986         Avoid variables used as mere abbreviations.
 987
 988 2001-12-05  Akim Demaille  <akim@epita.fr>
 989
 990         * src/lalr.c (traverse): Use arrays instead of pointers.
 991
 992 2001-12-05  Akim Demaille  <akim@epita.fr>
 993
 994         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
 995         the handling of squeue.
 996         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 997
 998 2001-12-05  Akim Demaille  <akim@epita.fr>
 999
1000         Because useless nonterminals are now kept alive (instead of being
1001         `destroyed'), we now sometimes examine them, and store information
1002         related to them.  Hence we need to know their number, and adjust
1003         memory allocations.
1004
1005         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1006         static.
1007         * src/LR0.c (allocate_itemsets): The memory allocated to
1008         `symbol_count' was used for two different purpose: once to count
1009         the number of occurrences of each symbol, and later reassigned to
1010         `shift_symbol', containing the symbol that can be shifted from a
1011         given state.
1012         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1013         only, and...
1014         (new_itemsets): Allocate `shift_symbol' here.
1015         (allocate_itemsets): symbol_count includes useless nonterminals.
1016         Make room for them.
1017         (free_storage): Use `free', not `XFREE', for pointers that cannot
1018         be null.
1019
1020 2001-12-05  Akim Demaille  <akim@epita.fr>
1021
1022         * src/nullable.c (set_nullable): Deobfuscate the handling of
1023         ritem.
1024         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1025
1026 2001-12-05  Akim Demaille  <akim@epita.fr>
1027
1028         * src/gram.c, src/gram.h (ritem_print): New.
1029         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1030         (This useless function was defined only to work around VMS linkers
1031         that can't handle compilation units with variables only).
1032         * src/reduce.c (dump_grammar): Use it to trace the construction of
1033         ritem.
1034
1035 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1036
1037         * src/bison.simple (union yyalloc): Change member names
1038         to be the same as the stack names.
1039         (yyparse): yyptr is now union yyalloc *, not char *.
1040         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1041         and may generate better code on some machines.
1042         (yystpcpy): Use prototype if __STDC__ is defined, not just
1043         if __cplusplus is defined.
1044
1045 2001-11-30  Akim Demaille  <akim@epita.fr>
1046
1047         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1048         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1049         Gettext doesn't compile cleanly, and dies with -Werror.
1050         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1051         Include WARNING_CFLAGS here.
1052         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1053         before being defined.
1054
1055 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1056
1057         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1058         First arg is int, not unsigned.
1059         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1060         (SIZE_MAX, UINT_MAX): New macros.
1061         (quotearg_n_options): Abort if N is negative.
1062         Avoid overflow check on hosts where size_t is 64 bits and int
1063         is 32 bits, as overflow is impossible there.
1064         Fix off-by-one typo that caused unnecessary reallocation.
1065
1066 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1067
1068         Name space cleanup in generated parser.
1069
1070         * doc/bison.texinfo (Bison Parser): Discuss system headers
1071         and their effect on the user name space.
1072
1073         * src/bison.simple:
1074         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1075         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1076         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1077
1078         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1079         on user names when possible.
1080
1081         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1082         Simplify test for whather <alloca.h> exists.
1083
1084         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1085
1086         (<stdio.h>): Include if YYDEBUG.
1087
1088         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1089         ! defined (yyoverflow) && ! defined (yymemcpy).
1090
1091         (yymemcpy, yyparse): Rename local variables as needed so that
1092         they all begin with 'yy'.
1093
1094         (yystrlen, yystpcpy): New functions.
1095
1096         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1097         All uses changed.
1098
1099         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1100         instead of relying on string.h functions.  Use YYSTACK_ALLOC

1119
1120         Instead of mapping the LHS of unused rules to -1, keep the LHS

1122

1157         (union yyalloc): New type.
1158         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1159         an arbitrary restriction on hosts where size_t is wider than int.
1160
1161         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1162         a parser stack overflow.  Allocate just one block of memory for all
1163         three stacks, instead of allocating three blocks; this typically is
1164         faster and reduces fragmentation.
1165
1166         Do not limit the number of items in the stack to a value that fits
1167         in 'int', as this is an arbitrary limit on hosts with 64-bit
1168         size_t and 32-bit int.

1224

1227
1228 2001-11-28  Akim Demaille  <akim@epita.fr>
1229
1230         * src/closure.c (closure): No longer optimize the special case
1231         where all the bits of `ruleset[r]' are set to 0, to make the code
1232         clearer.

1466         * src/derives.c: Likewise.
1467         * src/reduce.c: (inaccessable_symbols): Using if is better style
1468         than goto.

1595         * tests/calc.at, tests/output.at, tests/regression.at,
1596         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
1597         now the tests are run in private dirs, therefore AC_CLEANUP and

1599         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
1600         use abs. path to find config.h.

1625         arg_offset.
1626         arg is const.

2546 2001-08-27  Paul Eggert  <eggert@twinsun.com>
2547
2548         * src/bison.simple (yyparse): Don't take the address of an
2549         item before the start of an array, as that doesn't conform to
2550         the C Standard.
2551

2553
2554         * src/output.c (output): Remove the initialization of the macro
2555         obstack.  It was done too late here.

2558         completely wrong.

2595         string delimiters or not.
2596         (copy_string): Be a simple call to copy_string2 with the last argument
2597         bound to true.
2598         (read_declarations): Add case for macro definition.
2599         (copy_identifier): New.
2600         (parse_macro_decl): Read macro identifiers using copy_identifier
2601         rather than lex.
2602

2611         (output_trailers): Remove.
2612         (output): Disable call to 'reader_output_yylsp'.

2620         table with a macro. No output to the table obstack.
2621         (output_gram): Same for 'rhs' and 'prhs'.

2633
2634         * src/output.c (output_parser): Replace most of the skeleton copy code
2635         with something new. Skeletons are now processed character by character
2636         rather than line by line, and Bison looks for '%%' macros. This is the
2637         first step in making Bison's output process (a lot) more flexible.
2638         (output_parser): Use the macro table.

2964
2965 2001-02-21  Akim Demaille  <akim@epita.fr>
2966
2967         * src/reader.c (gensym): `gensym_count' is your own.
2968         Use a static buf to create the symbol name, as token_buffer is no
2969         longer a buffer.
2970
2971 2001-02-08  Akim Demaille  <akim@epita.fr>
2972
2973         * src/conflicts.c (conflict_report): Be sure not to append to res
2974         between two calls, which could happen if both first sprintf were

2977 2001-02-08  Akim Demaille  <akim@epita.fr>
2978
2979         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
2980         New, from fileutils 4.0.37.
2981         * configure.in: Require Autoconf 2.49c.  I took some time before
2982         making this decision.  This is the only way out for portability
2983         issues in Bison, it would mean way too much duplicate effort to
2984         import in Bison features implemented in 2.49c since 2.13.
2985         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

2996
2997         * src/lex.c (token_obstack): New.
2998         (init_lex): Initialize it.  No longer call...

3001

3003
3004         * src/lex.h: Rename all the tokens:
3005         s/\bENDFILE\b/tok_eof/g;
3006         s/\bIDENTIFIER\b/tok_identifier/g;
3007         etc.
3008         Let them be enums, not #define, to ease debugging.
3009         Adjust all the code.
3010
3011 2001-01-18  Akim Demaille  <akim@epita.fr>
3012
3013         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

3015
3016 2001-01-18  Akim Demaille  <akim@epita.fr>
3017
3018         Since we now use obstacks, more % directives can be enabled.
3019
3020         * src/lex.c (percent_table): Also accept `%yacc',
3021         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3022         `%debug'.
3023         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3024         instead of returning a token.
3025         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3026         * src/reader.c (read_declarations): Adjust.
3027         * src/files.c (open_files): Don't call `compute_base_names', don't
3028         compute `attrsfile' since they depend upon data which might be
3029         *in* the input file now.
3030         (output_files): Do it here.
3031         * src/output.c (output_headers): Document the fact that this patch
3032         introduces a guaranteed SEGV for semantic parsers.
3033         * doc/bison.texinfo: Document them.
3034         * tests/suite.at: Exercise these %options.
3035
3036 2000-12-20  Akim Demaille  <akim@epita.fr>
3037
3038         Also handle the output file (--verbose) with obstacks.

3040         * files.c (foutput): Remove.
3041         (output_obstack): New.

3050         * src/files.c (open_files): Fix the computation of short_base_name
3051         in the case of `-o foo.tab.c'.
3052
3053 2000-12-20  Akim Demaille  <akim@epita.fr>
3054
3055         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3056         (copy_dollar): Now that everything uses obstacks, get rid of the
3057         FILE * parameters.
3058
3059 2000-12-20  Akim Demaille  <akim@epita.fr>
3060
3061         * src/files.c (open_files): Actually the `.output' file is based
3062         on the short_base_name, not base_name.
3063         * tests/suite.at (Checking output file names): Adjust.
3064
3065 2000-12-20  Akim Demaille  <akim@epita.fr>
3066
3067         * src/bison.s1: Remove, we now use directly...
3068         * src/bison.simple: this.
3069         * src/Makefile.am: Use pkgdata instead of data.

3091         (stringappend): Be just like strcat but allocate.
3092         (base_names): Eve out from open_files.
3093         Try to simplify the rather hairy computation of base_name and
3094         short_base_name.
3095         (open_files): Use it.
3096         * tests/suite.at (Checking output file names): New test.

3106
3107 2000-12-19  Akim Demaille  <akim@epita.fr>
3108
3109         * src/output.c (output_parser): Compute the `#line' lines when
3110         there are.
3111         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

3113
3114 2000-12-19  Akim Demaille  <akim@epita.fr>
3115
3116         Let the handling of the skeleton files be local to the procedures
3117         that use it.

3135

3137         looking for `/tmp' since we have no tmp file.
3138
3139 2000-12-19  Akim Demaille  <akim@epita.fr>

3168         * lib/obstack.h: Formatting changes.
3169         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3170         prevents type checking.
3171         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3172         cast the value to (void *): assigning a `foo *' to a `void *'
3173         variable is valid.

3210
3211 2000-11-07  Akim Demaille  <akim@epita.fr>
3212
3213         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

3217
3218         * src/output.c (output): Remove useless variables.
3219         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3220         argument `data' for consistency with the prototypes.
3221         Qualify it `const'.
3222         (obstack_copy, obstack_copy0): Rename the second argument as
3223         `address' for consistency.  Qualify it `const'.

3237         For some reason, this was not applied.
3238
3239         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3255         * src/main.c (main): Don't use `atexit' to register `done', since
3256         it no longer has to remove tmp files, just call `output_files'
3257         when there are no errors.

3362         When a literal string is used to define two different tokens,
3363         `bison -v' segfaults.
3364         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3365
3366         * tests/regression.m4: New file.
3367         Include the core of the sample provided by Piotr Gackiewicz.
3368         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3369         properly.
3370
3371 2000-10-04  Akim Demaille  <akim@epita.fr>
3372
3373         * src/reader.c (parse_expect_decl): Keep `count' within the size
3374         of `buffer'.
3375         From Neil Booth.
3376
3377 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3378
3379         * bison.s1 (yyparse): Assign the default value
3380         unconditionally, to avoid a GCC warning and make the parser a
3381         tad smaller.
3382
3383 2000-10-02  Akim Demaille  <akim@epita.fr>
3384
3385         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3386         options.
3387
3388 2000-10-02  Akim Demaille  <akim@epita.fr>
3389
3390         * src/derives.c, src/print.c, src/reduce.c: To ease the
3391         translation, move some `\n' out of the translated strings.
3392
3393 2000-10-02  Akim Demaille  <akim@epita.fr>
3394
3395         The location tracking mechanism is precious for parse error
3396         messages.  Nevertheless, it is enabled only when `@n' is used in
3397         the grammar, which is a different issue (you can use it in error
3398         message, but not in the grammar per se).  Therefore, there should
3399         be another means to enable it.
3400
3401         * src/getargs.c (getargs): Support `--locations'.
3402         (usage): Report it.
3403         * src/getargs.h (locationsflag): Export it.
3404         * src/lex.c (percent_table): Support `%locations'.
3405         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3406         with `locationsflag'.
3407         * doc/bison.texinfo: Document `--locations' and `%locations'.
3408         Sort the options.
3409         * tests/calc.m4: Test it.
3410
3411         For regularity of the names, replace each
3412         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3413         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3414         In addition replace each `flag' with `_flag'.
3415
3416 2000-10-02  Akim Demaille  <akim@epita.fr>
3417
3418         Also test parse error messages, including with YYERROR_VERBOSE.
3419
3420         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3421         associative).
3422         Use it to check the computations.
3423         Use it to check `nonassoc' is honored.
3424         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3425         `--yyerror-verbose'.
3426         (_AT_CHECK_CALC): Adjust to this option.
3427         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3428
3429 2000-10-02  Akim Demaille  <akim@epita.fr>
3430
3431         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3432         the latter demonstrates a flaw in the handling of non debugging
3433         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3434         was used in order to simplify:
3435
3436         #if YYDEBUG
3437         if (yydebug)
3438         {
3439         ...
3440         }
3441         #endif
3442
3443         into
3444
3445         if (yydebug)
3446         {
3447         ...
3448         }
3449
3450         unfortunately this leads to a CPP conflict when
3451         `--name-prefix=foo' is used since it produces `#define yydebug
3452         foodebug'.
3453
3454         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3455         (YYDPRINTF): New macro.
3456         Spread its use.
3457         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3458         the bison options.
3459         Also test `--verbose', `--defines' and `--name-prefix'.
3460
3461 2000-10-02  Akim Demaille  <akim@epita.fr>
3462
3463         Improve the readability of the produced parsers.
3464
3465         * src/bison.s1: Formatting changes.
3466         Improve the comment related to the `$' mark.
3467         (yydefault): Don't fall through to `yyresume': `goto' there.
3468         * src/output.c (output_parser): When the `$' is met, skip the end
3469         of its line.
3470         New variable, `number_of_dollar_signs', to check there's exactly
3471         one `$' in the parser skeleton.
3472
3473 2000-10-02  Akim Demaille  <akim@epita.fr>
3474
3475         * lib/xstrdup.c: New file, from the fileutils.
3476         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3477         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3478         instead of strlen + xmalloc + strcpy.
3479         * src/symtab.c (copys): Remove, use xstrdup instead.
3480
3481 2000-10-02  Akim Demaille  <akim@epita.fr>
3482
3483         * src/gram.h (associativity): New enum type which replaces the
3484         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3485         `right_assoc', `left_assoc' and `non_assoc'.
3486         Adjust all dependencies.
3487         * src/reader.c: Formatting changes.
3488         (LTYPESTR): Don't define it, use it as a literal in
3489         `reader_output_yylsp'.
3490         * src/symtab.h (symbol_class): New enum type which replaces the
3491         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3492         `sunknown', `stoken and `snterm'.
3493
3494 2000-10-02  Akim Demaille  <akim@epita.fr>
3495
3496         * src/getargs.c (fixed_outfiles): Rename as...
3497         (yaccflag): for consistency and accuracy.
3498         Adjust dependencies.
3499
3500 2000-10-02  Akim Demaille  <akim@epita.fr>
3501
3502         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3503         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3504         difficult and introduced a lot of core dump.  It turns out that
3505         Bison used an implementation of `xmalloc' based on `calloc', and
3506         at various places it does depend upon the initialization to 0.  I
3507         have not tried to isolate the pertinent places, and all the former
3508         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3509         someone should address this issue.
3510
3511         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3512         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
3513         files.
3514         Adjust dependencies.

3518 2000-10-02  Akim Demaille  <akim@epita.fr>
3519
3520         Various anti-`extern in *.c' changes.
3521
3522         * src/system.h: Include `assert.h'.
3523
3524 2000-10-02  Akim Demaille  <akim@epita.fr>
3525
3526         * src/state.h (nstates, final_state, first_state, first_shift)
3527         (first_reduction): Move their exportation from here...
3528         * src/LR0.h: to here.
3529         Adjust dependencies.
3530         * src/getargs.c (statisticsflag): New variable.
3531         Add support for `--statistics'.

3603
3604 2000-10-02  Akim Demaille  <akim@epita.fr>
3605
3606         * src/output.c (token_actions): Introduce a temporary array,
3607         YYDEFACT, that makes it possible for this function to use
3608         output_short_table.
3609
3610 2000-10-02  Akim Demaille  <akim@epita.fr>
3611
3612         `user_toknums' is output as a `short[]' in `output.c', while it is
3613         defined as a `int[]' in `reader.c'.  For consistency with the
3614         other output tables, `user_toknums' is now defined as a table of
3615         shorts.
3616
3617         * src/reader.c (user_toknums): Be a short table instead of an int
3618         table.
3619         Adjust dependencies.
3620
3621         Factor the short table outputs.
3622
3623         * src/output.c (output_short_table): New function.
3624         * src/output.c (output_gram, output_stos, output_rule_data)

3626
3627 2000-10-02  Akim Demaille  <akim@epita.fr>
3628
3629         * src/output.c (output): Topological sort of the functions, in
3630         order to get rid of the `static' prototypes.
3631         No longer use `register'.
3632         * src/output.h: New file.
3633         Propagate its inclusion in files explicitly prototyping functions
3634         from output.c.
3635

3646         (new_closure, free_closure): these.  Adjust dependencies.
3647         * src/LR0.c: Formatting changes, topological sort, use of
3648         cloture.h.

3656         inclusion.
3657         Don't define PARAMS.
3658         * src/system.h: Define PARAMS.
3659         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3660         purpose of config.h.  system.h must not try to fix wrong
3661         definitions in config.h.
3662
3663 2000-09-20  Akim Demaille  <akim@epita.fr>

3675         Use these macros to test bison with options `', `--raw',
3676         `--debug', `--yacc', `--yacc --debug'.
3677
3678 2000-09-19  Akim Demaille  <akim@epita.fr>
3679
3680         * src/output.c: Formatting changes.

3698         portable.
3699

3739         (VERSION_STRING): Remove.
3740
3741 2000-04-14  Akim Demaille  <akim@epita.fr>
3742
3743         * src/reader.c (copy_comment2): New function, same as former

3798         * configure.in: Adjust.
3799         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

3823         the file name, not the whole `#line LINE FILE'.
3824
3825 2000-03-17  Akim Demaille  <akim@epita.fr>
3826
3827         On syntax errors, report the token on which we choked.
3828
3829         * src/bison.s1 (yyparse): In the label yyerrlab, when

3847
3848         * src/reader.c (copy_definition): Use copy_string and
3849         copy_comment.  Removed now unused `match', `ended',
3850         `cplus_comment'.
3851         (copy_comment, copy_string): Moved, to be visible from
3852         copy_definition.
3853
3854 2000-03-17  Akim Demaille  <akim@epita.fr>
3855
3856         * src/reader.c (copy_string): Declare `static inline'.  No
3857         problems with inline, since it is checked by configure.

3878
3879         Change the handling of @s so that they behave exactly like $s.
3880         There is now a pseudo variable @$ (readble and writable), location
3881         of the lhs of the rule (by default ranging from the location of
3882         the first symbol of the rhs, to the location of the last symbol,
3883         or, if the rhs is empty, YYLLOC).
3884
3885         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3886         yyval.
3887         (yyparse): When providing a default semantic action, provide a
3888         default location action.
3889         (after the $): No longer change `*YYLSP', just stack YYLOC the
3890         same way you stack YYVAL.
3891         * src/reader.c (read_declarations): Use warns.
3892         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3893         (copy_action, case '@'): Likewise.
3894         Use a standard error message, to save useless work from
3895         translators.
3896
3897 2000-03-17  Akim Demaille  <akim@epita.fr>
3898
3899         * src/bison.s1: Formatting and cosmetics changes.

3906         Makefile now handles them.
3907
3908 2000-03-16  Akim Demaille  <akim@epita.fr>
3909

3914
3915 2000-03-16  Akim Demaille  <akim@epita.fr>
3916
3917         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
3918         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3919         One `#if YYDEBUG' remains, since it uses variables which are
3920         defined only if `YYDEBUG != 0'.
3921
3922 2000-03-16  Akim Demaille  <akim@epita.fr>
3923
3924         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

3935 2000-03-16  Akim Demaille  <akim@epita.fr>
3936
3937         Do not hard code values of directories in `configure.in'.

3945         * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
3946         handled via src/Makefile.am.
3947         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
3948         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
3949         autoheader.

3954         the proper line number and file name.
3955         (DEFS): Propagate the location of bison library files and of the
3956         locale files.
3957         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
3958         builddir.
3959         * acinclude.m4: Remove, replaced by the directory m4.
