ChangeLog

   1 2001-12-29  Akim Demaille  <akim@epita.fr>
   2
   3         * tests/regression.at (Web2c Actions): Blindly move the actual
   4         output as expected output.  The contents *seem* right to me, but I
   5         can't pretend reading perfectly parser tables...  Nonetheless, all
   6         the other tests pass correctly, the table look OK, even though the
   7         presence of `$axiom' is to be noted: AFAICS it is useless (but
   8         harmless).
   9
  10
  11 2001-12-29  Akim Demaille  <akim@epita.fr>
  12
  13         * src/reader.c (readgram): Don't add the rule 0 if there were no
  14         rules read.  In other words, add it _after_ having performed
  15         grammar sanity checks.
  16         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
  17
  18
  19 2001-12-29  Akim Demaille  <akim@epita.fr>
  20
  21         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
  22         visible, and some states have now a different number.
  23
  24
  25 2001-12-29  Akim Demaille  <akim@epita.fr>
  26
  27         * src/reader.c (readgram): Bind the initial rule's lineno to that
  28         of the first rule.
  29         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
  30         (Solved SR Conflicts): Adjust rule 0's line number.
  31
  32
  33 2001-12-29  Akim Demaille  <akim@epita.fr>
  34
  35         Fix the `GAWK Grammar' failure.
  36
  37         * src/LR0.c (final_state): Initialize to -1 so that we do compute
  38         the reductions of the first state which was mistakenly confused
  39         with the final state because precisely final_state was initialized
  40         to 0.
  41         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
  42         now noticed by Bison.
  43         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
  44         have a reduction on $default.
  45
  46
  47 2001-12-29  Akim Demaille  <akim@epita.fr>
  48
  49         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
  50         rule line numbers.
  51         * src/closure.c (print_closure): Likewise.
  52         * src/derives.c (print_derives): Likewise.
  53         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
  54         now.
  55
  56 2001-12-29  Akim Demaille  <akim@epita.fr>
  57
  58         * src/lalr.c (lookaheads_print): New.
  59         (lalr): Call it when --trace-flag.
  60         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
  61         are dumped.
  62
  63
  64 2001-12-29  Akim Demaille  <akim@epita.fr>
  65
  66         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
  67         when walking through ritem, even via rule->rhs.
  68         * src/reduce.c (dump_grammar, useful_production, reduce_output)
  69         (useful_production, useless_nonterminals): Likewise.
  70         (reduce_grammar_tables): Likewise, plus update nritems.
  71         * src/nullable.c (set_nullable): Likewise.
  72         * src/lalr.c (build_relations): Likewise.
  73         * tests/sets.at (Nullable): Adjust.
  74         Fortunately, now, the $axiom is no longer nullable.
  75
  76
  77 2001-12-29  Akim Demaille  <akim@epita.fr>
  78
  79         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
  80         the 0-sentinel.
  81         * src/gram.c (ritem_longest_rhs): Likewise.
  82         * src/reduce.c (nonterminals_reduce): Likewise.
  83         * src/print_graph.c (print_graph): Likewise.
  84         * src/output.c (output_rule_data): Likewise.
  85         * src/nullable.c (set_nullable):  Likewise.
  86
  87 2001-12-29  Akim Demaille  <akim@epita.fr>
  88
  89         * src/output.c: Comment changes.
  90
  91 2001-12-27  Paul Eggert  <eggert@twinsun.com>
  92
  93         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
  94         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
  95         Sparc, as they were causing more porting problems than the
  96         (minor) performance improvement was worth.
  97
  98         Also, catch up with 1.31's YYSTD.
  99
 100 2001-12-27  Akim Demaille  <akim@epita.fr>
 101
 102         * src/output.c (output_gram): Rely on nritems, not the
 103         0-sentinel.  See below.
 104         Use -1 as separator, not 0.
 105         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 106         Rely on -1 as separator in yyrhs, instead of 0.
 107         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 108         twice `Now at end of input', therefore there are two lines less to
 109         expect.
 110
 111 2001-12-27  Akim Demaille  <akim@epita.fr>
 112
 113         * tests/regression.at (Unresolved SR Conflicts):
 114         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 115         below.
 116
 117 2001-12-27  Akim Demaille  <akim@epita.fr>
 118
 119         * src/LR0.c (new_state): Recognize the final state by the fact it
 120         is reached by eoftoken.
 121         (insert_start_shifting_state, insert_eof_shifting_state)
 122         (insert_accepting_state, augment_automaton): Remove, since now
 123         these states are automatically computed from the initial state.
 124         (generate_states): Adjust.
 125         * src/print.c: When reporting a rule number to the user, substract
 126         1, so that the axiom rule is rule 0, and the first user rule is 1.
 127         * src/reduce.c: Likewise.
 128         * src/print_graph.c (print_core): For the time being, just as for
 129         the report, depend upon --trace-flags to dump the full set of
 130         items.
 131         * src/reader.c (readgram): Once the grammar read, insert the rule
 132         0: `$axiom: START-SYMBOL $'.
 133         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 134         number of the states has changed (the final state is no longer
 135         necessarily the last), catch up.
 136
 137 2001-12-27  Akim Demaille  <akim@epita.fr>
 138
 139         Try to make the use of the eoftoken valid.  Given that its value
 140         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 141         is used instead of > 0 where appropriate, (ii), depend upon nritems
 142         instead of the 0-sentinel.
 143
 144         * src/gram.h, src/gram.c (nritems): New.
 145         Expected to be duplication of nitems, but for the time being...
 146         * src/reader.c (packgram): Assert nritems and nitems are equal.
 147         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 148         * src/closure.c (print_closure, print_fderives): Likewise.
 149         * src/gram.c (ritem_print): Likewise.
 150         * src/print.c (print_core, print_grammar): Likewise.
 151         * src/print_graph.c: Likewise.
 152
 153 2001-12-27  Akim Demaille  <akim@epita.fr>
 154
 155         * src/main.c (main): If there are complains after grammar
 156         reductions, then output the report anyway if requested, then die.
 157         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 158         * src/reader.c (eoftoken): New.
 159         (parse_token_decl): If the token being defined has value `0', it
 160         is the eoftoken.
 161         (packsymbols): No longer hack `tags' to insert `$' by hand.
 162         Be sure to preserve the value of the eoftoken.
 163         (reader): Make sure eoftoken is defined.
 164         Initialize nsyms to 0: now eoftoken is created just like the others.
 165         * src/print.c (print_grammar): Don't special case the eof token.
 166         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 167         lie anyway, albeit pleasant.
 168         * tests/calc.at: Exercise error messages with eoftoken.
 169         Change the grammar so that empty input is invalid.
 170         Adjust expectations.
 171         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 172
 173 2001-12-27  Akim Demaille  <akim@epita.fr>
 174
 175         * configure.in: Check the protos of strchr ans strspn.
 176         Replace strchr if needed.
 177         * src/system.h: Provide the protos of strchr, strspn and memchr if
 178         missing.
 179         * lib/strchr.c: New.
 180         * src/reader.c (symbols_save): Use strchr.
 181
 182 2001-12-27  Akim Demaille  <akim@epita.fr>
 183
 184         * src/print.c, src/print_graph.c (escape): New.
 185         Use it to quote the TAGS outputs.
 186         * src/print_graph.c (print_state): Now errors are in red, and
 187         reductions in green.
 188         Prefer high to wide: output the state number on a line of its own.
 189
 190 2001-12-27  Akim Demaille  <akim@epita.fr>
 191
 192         * src/state.h, src/state.c (reductions_new): New.
 193         * src/LR0.c (set_state_table): Let all the states have a
 194         `reductions', even if reduced to 0.
 195         (save_reductions): Adjust.
 196         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 197         * src/print.c (print_reductions, print_actions): Adjust.
 198         * src/output.c (action_row): Adjust.
 199
 200 2001-12-27  Akim Demaille  <akim@epita.fr>
 201
 202         * src/state.h, src/state.c (errs_new, errs_dup): New.
 203         * src/LR0.c (set_state_table): Let all the states have an errs,
 204         even if reduced to 0.
 205         * src/print.c (print_errs, print_reductions): Adjust.
 206         * src/output.c (output_actions, action_row): Adjust.
 207         * src/conflicts.c (resolve_sr_conflict): Adjust.
 208
 209 2001-12-27  Akim Demaille  <akim@epita.fr>
 210
 211         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 212
 213 2001-12-27  Akim Demaille  <akim@epita.fr>
 214
 215         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 216         * src/print.c: here.
 217         (lookaheadset, shiftset): New, used as additional storage by
 218         print_reductions.
 219         (print_results): Adjust.
 220         (print_shifts, print_gotos, print_errs): New, extracted from...
 221         (print_actions): here.
 222         * src/print_graph.c (print_actions): Remove dead code.
 223
 224 2001-12-27  Akim Demaille  <akim@epita.fr>
 225
 226         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 227         `$n' and `@n'.
 228
 229 2001-12-27  Akim Demaille  <akim@epita.fr>
 230
 231         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 232         (build_relations): Adjust.
 233
 234 2001-12-27  Akim Demaille  <akim@epita.fr>
 235
 236         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 237         duplication.
 238
 239 2001-12-27  Akim Demaille  <akim@epita.fr>
 240
 241         * src/reader.c (packgram): Catch nitems overflows.
 242
 243 2001-12-27  Akim Demaille  <akim@epita.fr>
 244
 245         * src/files.c, src/files.h (guard_obstack): Remove.
 246         * src/output.c (output): Adjust.
 247         * src/reader.c (parse_braces): New, factoring...
 248         (copy_action, copy_guard): these two which are renamed as...
 249         (parse_action, parse_guard): these.
 250         As a voluntary consequence, using braces around guards is now
 251         mandatory.
 252
 253 2001-12-27  Akim Demaille  <akim@epita.fr>
 254
 255         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 256         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 257         members.
 258         (symbol_list_new): Adjust.
 259         (copy_action): action_line is the first line, not the last.
 260         (copy_guard): Just as for actions, store the `action' only, not
 261         the switch/case/break flesh.
 262         Don't parse the user action that might follow the guard, let...
 263         (readgram): do it, i.e., now, there can be an action after a
 264         guard.
 265         In other words the guard is just explicitly optional.
 266         (packgram): Adjust.
 267         * src/output.c (guards_output): New.
 268         (output_parser): Call it when needed.
 269         (output): Also free the guard and attrs obstacks.
 270         * src/files.c, src/files.h (obstack_save): Remove.
 271         (output_files): Remove.
 272         As a result, if one needs the former `.act' file, using an
 273         appropriate skeleton which requires actions and guards is now
 274         required.
 275         * src/main.c (main): Adjust.
 276         * tests/semantic.at: New.
 277         * tests/regression.at: Use `input.y' as input file name.
 278         Avoid 8+3 problems by requiring input.c when the test needs the
 279         parser.
 280
 281 2001-12-27  Akim Demaille  <akim@epita.fr>
 282
 283         * src/reader.c (symbol_list_new): Be sure to initialize all the
 284         fields.
 285
 286 2001-12-27  Akim Demaille  <akim@epita.fr>
 287
 288         All the hacks using a final pseudo state are now useless.
 289
 290         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 291         * src/lalr.c (nLA): New.
 292         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 293         instead of lookaheadsp from the pseudo state (nstate + 1).
 294
 295 2001-12-27  Akim Demaille  <akim@epita.fr>
 296
 297         * src/output.c (action_row, token_actions): Use a state_t instead
 298         of a integer, and nlookaheads instead of the following state's
 299         lookaheadsp.
 300
 301 2001-12-27  Akim Demaille  <akim@epita.fr>
 302
 303         * src/conflicts.c (log_resolution, flush_shift)
 304         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 305         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 306         (conflicts_print, print_reductions): Use a state_t instead of an
 307         integer when referring to a state.
 308         As much as possible, depend upon nlookaheads, instead of the
 309         `lookaheadsp' member of the following state (since lookaheads of
 310         successive states are successive, the difference between state n + 1
 311         and n served as the number of lookaheads for state n).
 312         * src/lalr.c (add_lookback_edge): Likewise.
 313         * src/print.c (print_core, print_actions, print_state)
 314         (print_results): Likewise.
 315         * src/print_graph.c (print_core, print_actions, print_state)
 316         (print_graph): Likewise.
 317         * src/conflicts.h: Adjust.
 318
 319 2001-12-27  Akim Demaille  <akim@epita.fr>
 320
 321         * src/bison.hairy: Formatting/comment changes.
 322         ANSIfy.
 323         Remove `register' indications.
 324         Add plenty of `static'.
 325
 326 2001-12-27  Akim Demaille  <akim@epita.fr>
 327
 328         * src/output.c (prepare): Drop the muscle `ntbase' which
 329         duplicates ntokens.
 330         * src/bison.simple: Formatting/comment changes.
 331         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 332         is an undocumented synonym.
 333
 334 2001-12-22  Akim Demaille  <akim@epita.fr>
 335
 336         * src/output.c (output_table_data): Change the prototype to use
 337         `int' for array ranges: some invocations do pass an int, not a
 338         short.
 339         Reported by Wayne Green.
 340
 341 2001-12-22  Akim Demaille  <akim@epita.fr>
 342
 343         Some actions of web2c.y are improperly triggered.
 344         Reported by Mike Castle.
 345
 346         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 347         * tests/regression.at (Web2c): Rename as...
 348         (Web2c Report): this.
 349         (Web2c Actions): New.
 350
 351 2001-12-22  Akim Demaille  <akim@epita.fr>
 352
 353         Reductions in web2c.y are improperly reported.
 354         Reported by Mike Castle.
 355
 356         * src/conflicts.c (print_reductions): Fix.
 357         * tests/regression.at (Web2c): New.
 358

 361         Some host fail on `assert (!"foo")', which expands to
 362         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 363         Reported by Nelson Beebee.
 364
 365         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 366         `#define it_succeeded 0' and `assert (it_succeeded)'.
 367
 368 2001-12-17  Marc Autret  <autret_m@epita.fr>
 369
 370         * src/bison.simple: Don't hard code the skeleton line and filename.
 371         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 372         New line counter 'skeleton_line' (skeleton-line muscle).
 373
 374 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 375
 376         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 377         YYDEBUG must be defined to a nonzero value.
 378
 379         * src/bison.simple (yytname): Do not assume that the user defines
 380         YYDEBUG to a properly parenthesized expression.
 381
 382 2001-12-17  Akim Demaille  <akim@epita.fr>
 383
 384         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 385         nlookaheads is a new member.
 386         Adjust all users.
 387         * src/lalr.h (nlookaheads): Remove this orphan declaration.
 388         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 389         state.
 390
 391 2001-12-17  Akim Demaille  <akim@epita.fr>
 392
 393         * src/files.h, src/files.c (open_files, close_files): Remove.
 394         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 395         let...
 396         * src/reader.c (reader): Do it.
 397
 398 2001-12-17  Akim Demaille  <akim@epita.fr>
 399
 400         * src/conflicts.c (print_reductions): Formatting changes.
 401
 402 2001-12-17  Akim Demaille  <akim@epita.fr>
 403
 404         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 405         (flush_reduce): New.
 406         (resolve_sr_conflict): Adjust.
 407
 408 2001-12-17  Akim Demaille  <akim@epita.fr>
 409
 410         * src/output.c (output_obstack): Be static and rename as...
 411         (format_obstack): this, to avoid any confusion with files.c's
 412         output_obstack.
 413         * src/reader.h (muscle_obstack): Move to...
 414         * src/output.h: here, since it's defined in output.c.
 415
 416 2001-12-17  Akim Demaille  <akim@epita.fr>
 417
 418         * src/output.c (action_row, save_column, default_goto)
 419         (sort_actions, matching_state, pack_vector): Better variable
 420         locality.
 421
 422 2001-12-17  Akim Demaille  <akim@epita.fr>
 423
 424         * src/output.c: Various formatting changes.
 425
 426 2001-12-17  Akim Demaille  <akim@epita.fr>
 427
 428         * src/files.c (output_files): Free the output_obstack.
 429         * src/main.c (main): Call print and print_graph conditionally.
 430         * src/print.c (print): Work unconditionally.
 431         * src/print_graph.c (print_graph): Work unconditionally.
 432         * src/conflicts.c (log_resolution): Output only if verbose_flag.
 433
 434 2001-12-16  Marc Autret  <autret_m@epita.fr>
 435
 436         * src/output.c (actions_output): Fix. When we use %no-lines,
 437         there is one less line per action.
 438
 439 2001-12-16  Marc Autret  <autret_m@epita.fr>
 440
 441         * src/bison.simple: Remove a useless #line directive.
 442         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 443         * src/output.c (get_lines_number): New.
 444         (output_parser): Adjust, now takes care about the lines of a
 445         output muscles.
 446         Fix line numbering.
 447         (actions_output): Computes the number of lines taken by actions.
 448         (output_master_parser): Insert new skeleton which is the name of
 449         the output parser file name.
 450
 451 2001-12-15  Marc Autret  <autret_m@epita.fr>
 452
 453         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
 454
 455 2001-12-15  Marc Autret  <autret_m@epita.fr>
 456
 457         * src/output.c (output_gram): Keep track of the hairy one.
 458
 459 2001-12-15  Akim Demaille  <akim@epita.fr>
 460
 461         Make `make distcheck' work.
 462
 463         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 464         system.h which uses libgettext.h.
 465
 466 2001-12-15  Akim Demaille  <akim@epita.fr>
 467
 468         * src/nullable.c (set_nullable): Useless rules must be skipped,
 469         otherwise, since we range over their symbols, we might look at a
 470         nonterminal which no longer ``exists'', i.e., it is not counted in
 471         `nvars', hence we overflow our arrays.
 472
 473 2001-12-15  Akim Demaille  <akim@epita.fr>
 474
 475         The header can also be produced directly, without any obstack!
 476         Yahoo!
 477
 478         * src/files.c, src/files.h (defines_obstack): Remove.
 479         (compute_header_macro): Global.
 480         (defines_obstack_save): Remove.
 481         * src/reader.c (parse_union_decl): No longer output to
 482         defines_obstack: its content can be found in the `stype' muscle
 483         anyway.
 484         (output_token_translations): Merge into...
 485         (symbols_output): this.
 486         Rename as...
 487         (symbols_save): this.
 488         (reader): Adjust.
 489         * src/output.c (header_output): New.
 490         (output): Call it.
 491
 492 2001-12-15  Akim Demaille  <akim@epita.fr>
 493
 494         * src/reader.c (parse_union_decl): Instead of handling two obstack
 495         simultaneously, use one to define the `stype' muscle, and use the
 496         value of the latter to fill defines_obstack.
 497         (copy_comment): Remove.
 498         (copy_comment2): Work for a single obstack.
 499         Rename as...
 500         (copy_comment): this.
 501
 502 2001-12-15  Akim Demaille  <akim@epita.fr>
 503
 504         * src/lex.c, src/lex.h (xgetc): No longer static.
 505         * src/reader.c (parse_union_decl): Revamp.
 506
 507 2001-12-15  Akim Demaille  <akim@epita.fr>
 508
 509         Still making progress in separating Bison into (i) input, (ii)
 510         process, (iii) output: now we can directly output the parser file
 511         without using table_obstack at all.
 512
 513         * src/files.c, src/files.h (table_obstack): Bye bye.
 514         (parser_file_name): New.
 515         * src/files.c (compute_output_file_names): Compute it.
 516         * src/output.c (actions_output, output_parser)
 517         (output_master_parser): To a file instead of an obstack.
 518
 519 2001-12-15  Akim Demaille  <akim@epita.fr>
 520
 521         Attach actions to rules, instead of pre-outputting them to
 522         actions_obstack.
 523
 524         * src/gram.h (rule_t): action and action_line are new members.
 525         * src/reader.c (symbol_list): Likewise.
 526         (copy_action): Save the actions within the rule.
 527         (packgram): Save them in rule_table.
 528         * src/output.c (actions_output): New.
 529         (output_parser): Use it on `%%actions'.
 530         (output_rule_data): Don't free rule_table.
 531         (output): Do it.
 532         (prepare): Don't save the `action' muscle.
 533         * src/bison.simple: s/%%action/%%actions/.
 534
 535 2001-12-15  Akim Demaille  <akim@epita.fr>
 536
 537         * src/reader.c (copy_action): When --yacc, don't append a `;'
 538         to the user action: let it fail if lacking.
 539         Suggested by Arnold Robbins and Tom Tromey.
 540
 541 2001-12-14  Akim Demaille  <akim@epita.fr>
 542
 543         * src/lex.c (literalchar): Simply return the char you decoded, non
 544         longer mess around with obstacks and int pointers.
 545         Adjust all callers.
 546
 547 2001-12-14  Akim Demaille  <akim@epita.fr>
 548
 549         * src/lex.c (literalchar): Don't escape the special characters,
 550         just decode them, and keep them as char (before, eol was output as
 551         the 2 char string `\n' etc.).
 552         * src/output.c (output_rule_data): Use quotearg to output the
 553         token strings.
 554
 555 2001-12-13  Paul Eggert  <eggert@twinsun.com>
 556
 557         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
 558         Do not infringe on the global user namespace when using C++.
 559         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
 560         All uses of `fprintf' and `stderr' changed.
 561
 562         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
 563
 564 2001-12-13  Akim Demaille  <akim@epita.fr>
 565
 566         The computation of nullable is broken: it doesn't handle empty
 567         RHS's properly.
 568
 569         * tests/torture.at (GNU AWK Grammar): New.
 570         * tests/sets.at (Nullable): New.
 571         * src/nullable.c (set_nullable): Instead of blindly looping over
 572         `ritems', loop over the rules, and then over their rhs's.
 573
 574         Work around Autotest bugs.
 575
 576         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
 577         frame, because Autotest understand lines starting with a `+' as
 578         traces from the shell.  Then, they are not processed properly.
 579         Admittedly an Autotest bug, but we don't have time to wait for
 580         Autotest to catch up.
 581         * tests/regression.at (Broken Closure): Adjust to the new table
 582         frames.
 583         Move to...
 584         * tests/sets.at: here.
 585
 586 2001-12-13  Akim Demaille  <akim@epita.fr>
 587
 588         * src/closure.c (closure): Use nrules instead of playing tricks
 589         with BITS_PER_WORD.
 590
 591 2001-12-13  Akim Demaille  <akim@epita.fr>
 592
 593         * src/print.c (print_actions): Output the handling of `$' as the
 594         traces do: shifting the token EOF.  Before EOF was treated as a
 595         nonterminal.
 596         * tests/regression.at: Adjust some tests.
 597         * src/print_graph.c (print_core): Complete the set of items via
 598         closure.  The next-to-final and final states are still unsatisfying,
 599         but that's to be addressed elsewhere.
 600         No longer output the rule numbers, but do output the state number.
 601         A single loop for the shifts + gotos is enough, but picked a
 602         distinct color for each.
 603         (print_graph): Initialize and finalize closure.
 604
 605 2001-12-13  Akim Demaille  <akim@epita.fr>
 606
 607         * src/reader.c (readgram): Remove dead code, an strip useless
 608         braces.
 609         (get_type): Remove, unused.
 610
 611 2001-12-12  Akim Demaille  <akim@epita.fr>
 612
 613         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 614         on that of lib/error.c.
 615
 616 2001-12-12  Akim Demaille  <akim@epita.fr>
 617
 618         Some hosts don't like `/' in includes.
 619
 620         * src/system.h: Include libgettext.h without qualifying the path.
 621         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 622         $(top_srcdir).
 623
 624 2001-12-11  Marc Autret  <autret_m@epita.fr>
 625
 626         * src/output.c (output_parser): Remove useless muscle.
 627
 628 2001-12-11  Marc Autret  <autret_m@epita.fr>
 629
 630         * src/bison.simple: Remove #line just before %%epilogue. It
 631         is now handled in ...
 632         * src/reader.c (read_additionnal_code): Add the output of a
 633         #line for the epilogue.
 634
 635 2001-12-10  Marc Autret  <autret_m@epita.fr>
 636
 637         * src/reader.c (copy_definition): Re-use CPP-outed code which
 638         replace precedent remove.
 639         * src/bison.simple: Remove #line before %%prologue because
 640         %%input-line is wrong at this time.
 641
 642 2001-12-10  Marc Autret  <autret_m@epita.fr>
 643
 644         * src/reader.c (symbols_output): Clean up.
 645         * src/output.c (output_gram, output): Clean up.
 646
 647 2001-12-10  Akim Demaille  <akim@epita.fr>
 648
 649         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 650         * src/LR0.c (set_state_table): here.
 651         * src/lalr.c (lalr): Call it.
 652
 653 2001-12-10  Akim Demaille  <akim@epita.fr>
 654
 655         * src/state.h (shifts): Remove the `number' member: shifts are
 656         attached to state, hence no longer need to be labelled with a
 657         state number.
 658
 659 2001-12-10  Akim Demaille  <akim@epita.fr>
 660
 661         Now that states have a complete set of members, the linked list of
 662         shifts is useless: just fill directly the state's shifts member.
 663
 664         * src/state.h (shifts): Remove the `next' member.
 665         * src/LR0.c (first_state, last_state): Remove.
 666         Adjust the callers.
 667         (augment_automaton): Don't look for the shifts that must be added
 668         a shift on EOF: it is those of the state we looked for!  But now,
 669         since shifts are attached, it is no longer needed to looking
 670         merely by its id: its number.
 671
 672 2001-12-10  Akim Demaille  <akim@epita.fr>
 673
 674         * src/LR0.c (augment_automaton): Better variable locality.
 675         Remove an impossible branch: if there is a state corresponding to
 676         the start symbol being shifted, then there is shift for the start
 677         symbol from the initial state.
 678
 679 2001-12-10  Akim Demaille  <akim@epita.fr>
 680
 681         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 682         only when appropriate: when insert_start_shifting_state' is not
 683         invoked.
 684         * tests/regression.at (Rule Line Numbers): Adjust.
 685
 686 2001-12-10  Akim Demaille  <akim@epita.fr>
 687
 688         * src/LR0.c (augment_automaton): Now that all states have shifts,
 689         merge the two cases addition shifts to the initial state.
 690
 691 2001-12-10  Akim Demaille  <akim@epita.fr>
 692
 693         * src/lalr.c (set_state_table): Move to...
 694         * src/LR0.c: here.
 695         * src/lalr.c (lalr): Don't call it...
 696         * src/LR0.c (generate_states): do it.
 697         * src/LR0.h (first_state): Remove, only the table is used.
 698
 699 2001-12-10  Akim Demaille  <akim@epita.fr>
 700
 701         * src/LR0.h (first_shift, first_reduction): Remove.
 702         * src/lalr.c: Don't use first_shift: find shifts through the
 703         states.
 704
 705 2001-12-10  Akim Demaille  <akim@epita.fr>
 706
 707         * src/LR0.c: Attach shifts to states as soon as they are
 708         computed.
 709         * src/lalr.c (set_state_table): Instead of assigning shifts to
 710         state, just assert that the mapping was properly done.
 711
 712 2001-12-10  Akim Demaille  <akim@epita.fr>
 713
 714         * src/LR0.c (insert_start_shift): Rename as...
 715         (insert_start_shifting_state): this.
 716         (insert_eof_shifting_state, insert_accepting_state): New.
 717         (augment_automaton): Adjust.
 718         Better locality of the variables.
 719         When looking if the start_symbol is shifted from the initial
 720         state, using `while (... symbol != start_symbol ...)' sounds
 721         better than `while (... symbol < start_symbol ...)': If fail
 722         to see how the order between symbols could be relevant!
 723
 724 2001-12-10  Akim Demaille  <akim@epita.fr>
 725
 726         * src/getargs.h: Don't declare `spec_name_prefix' and
 727         `spec_file_prefix', declared by src/files.h.
 728         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 729         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 730         * src/output.c (prepare): Adjust.
 731         * src/reader.c (symbols_output): Likewise.
 732         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 733
 734 2001-12-10  Akim Demaille  <akim@epita.fr>
 735
 736         * src/muscle_tab.c (muscle_init): NULL is a better default than
 737         `"0"'.
 738
 739 2001-12-10  Akim Demaille  <akim@epita.fr>
 740
 741         * src/reader.c (reader): Calling symbols_output once is enough.
 742
 743 2001-12-10  Akim Demaille  <akim@epita.fr>
 744
 745         Now that states have a complete set of members, the linked list of
 746         reductions is useless: just fill directly the state's reductions
 747         member.
 748
 749         * src/state.h (struct reductions): Remove member `number' and
 750         `next'.
 751         * src/LR0.c (first_reduction, last_reduction): Remove.
 752         (save_reductions): Don't link the new reductions, store them in
 753         this_state.
 754         * src/lalr.c (set_state_table): No need to attach reductions to
 755         states, it's already done.
 756         * src/output.c (output_actions): No longer free the shifts, then
 757         the reductions, then the states: free all the states and their
 758         members.
 759
 760 2001-12-10  Akim Demaille  <akim@epita.fr>
 761
 762         * src/options.c (OPTN, DRTV, BOTH): New.
 763         (option_table): Use them.
 764
 765         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 766         the job of system.h.
 767         * src/options.c: Don't include stdio.h and xalloc.h for the same
 768         reasons.
 769
 770 2001-12-10  Akim Demaille  <akim@epita.fr>
 771
 772         * src/output.c (output, prepare): Make sure the values of the
 773         muscles `action' and `prologue' are 0-terminated.
 774
 775 2001-12-10  Akim Demaille  <akim@epita.fr>
 776
 777         Clean up GCC warnings.
 778
 779         * src/reader.c (copy_action): `buf' is not used.
 780         (parse_skel_decl): Be static.
 781         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 782         * src/options.h (create_long_option_table): Have a real prototype.
 783         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 784         (hash_delete_at): Return const void *.
 785         Adjust casts to preserve the const.
 786
 787 2001-12-10  Akim Demaille  <akim@epita.fr>
 788
 789         * configure.in: Require 2.52g.
 790         M4 is not needed, but AUTOM4TE is.
 791         * m4/m4.m4: Remove.
 792         * tests/Makefile.am: Adjust.
 793
 794 2001-12-10  Akim Demaille  <akim@epita.fr>
 795
 796         One structure for states is enough, even though theoretically
 797         there are LR(0) states and LALR(1) states.
 798
 799         * src/lalr.h (state_t): Remove.
 800         (state_table): Be state_t **, not state_t *.
 801         * src/state.h (core, CORE_ALLOC): Rename as...
 802         (state_t, STATE_ALLOC): this.
 803         Add the LALR(1) members: shifts, reductions, errs.
 804         * src/LR0.c (state_table): Rename as...
 805         (state_hash): this, to avoid name clashes with the global
 806         `state_table'.
 807         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 808         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 809
 810 2001-12-10  Akim Demaille  <akim@epita.fr>
 811
 812         Bison dumps core on bash.y.
 813         Reported by Pascal Bart.
 814
 815         * src/warshall.c (bitmatrix_print): New.
 816         (TC): Use it.
 817         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 818         j must be the outer loop.
 819         * tests/regression.at (Broken Closure): New.
 820
 821 2001-12-05  Akim Demaille  <akim@epita.fr>
 822
 823         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 824         its argument.
 825         Reported by Peter Hámorský.
 826
 827 2001-12-05  Akim Demaille  <akim@epita.fr>
 828
 829         * src/conflicts.c (err_table): Remove.
 830         (resolve_sr_conflict): Adjust.
 831         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 832         Rename as...
 833         (state_t.reductions, state_t.shifts): this.
 834
 835 2001-12-05  Akim Demaille  <akim@epita.fr>
 836
 837         * src/reduce.c (reduce_grammar_tables): No longer disable the
 838         removal of useless rules via CPP but via `if (0)', so that the
 839         compiler still check the code is valid.
 840         For instance, it should have noticed `rline' no longer exists: use
 841         the `line' member of rule_t.
 842         * src/gram.c (dummy, rline): Remove, unused.
 843
 844 2001-12-05  Akim Demaille  <akim@epita.fr>
 845
 846         * src/output.c (pack_vector): Use assert, not berror.
 847         * src/main.c (berror): Remove, unused.
 848
 849 2001-12-05  Akim Demaille  <akim@epita.fr>
 850
 851         New experimental feature: if --verbose --trace output all the
 852         items of a state, not only its kernel.
 853
 854         * src/print.c (print_core): If `trace_flag', then invoke closure
 855         before outputting the items of the state (print_core is no longer
 856         a correct name them).
 857         (print_results): Invoke new_closure/free_closure if needed.
 858
 859 2001-12-05  Akim Demaille  <akim@epita.fr>
 860
 861         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 862         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 863         (nitemset): for consistency with the rest of the project.
 864
 865 2001-12-05  Akim Demaille  <akim@epita.fr>
 866
 867         * src/closure.c (print_closure): Improve.
 868         (closure): Use it for printing input and output.
 869
 870 2001-12-05  Akim Demaille  <akim@epita.fr>
 871
 872         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 873         indexed by nonterminals.
 874
 875 2001-12-05  Akim Demaille  <akim@epita.fr>
 876
 877         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 878         what it was!).
 879         * src/warshall.h: Remove accidental duplication of the content.
 880
 881 2001-12-05  Akim Demaille  <akim@epita.fr>
 882
 883         * src/closure.c (set_fderives): De-obfuscate.
 884
 885 2001-12-05  Akim Demaille  <akim@epita.fr>
 886
 887         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
 888
 889 2001-12-05  Akim Demaille  <akim@epita.fr>
 890
 891         * src/closure.c (set_firsts): De-obfuscate.
 892
 893 2001-12-05  Akim Demaille  <akim@epita.fr>
 894
 895         * src/output.c (action_row): De-obfuscate
 896         using the good o' techniques: arrays not pointers, variable
 897         locality, BITISSET, RESETBIT etc.
 898
 899 2001-12-05  Akim Demaille  <akim@epita.fr>
 900
 901         Pessimize the code to simplify it: from now on, all the states
 902         have a valid SHIFTS, which NSHIFTS is possibly 0.
 903
 904         * src/LR0.c (shifts_new): Be global and move to..
 905         * src/state.c, src/state.h: here.
 906         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 907         * src/print_graph: Adjust.
 908
 909 2001-12-05  Akim Demaille  <akim@epita.fr>
 910
 911         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 912         * src/conflicts.c: Use it.
 913         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 914         incorrectly ``simplified''.
 915
 916 2001-12-05  Akim Demaille  <akim@epita.fr>
 917
 918         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
 919         using the good o' techniques: arrays not pointers, variable
 920         locality, BITISSET, RESETBIT etc.
 921
 922 2001-12-05  Akim Demaille  <akim@epita.fr>
 923
 924         * src/state.h (SHIFT_SYMBOL): New.
 925         * src/conflicts.c: Use it to deobfuscate.
 926
 927 2001-12-05  Akim Demaille  <akim@epita.fr>
 928
 929         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
 930         (print_reductions): De-obfuscate using the good o' techniques:
 931         arrays not pointers, variable locality, BITISSET.
 932
 933 2001-12-05  Akim Demaille  <akim@epita.fr>
 934
 935         * src/conflicts.c (print_reductions): Arrays, not pointers.
 936         Use BITISSET.
 937
 938 2001-12-05  Akim Demaille  <akim@epita.fr>
 939
 940         * src/conflicts.c (print_reductions): Pessimize, but clarify.
 941
 942 2001-12-05  Akim Demaille  <akim@epita.fr>
 943
 944         * src/conflicts.c (print_reductions): Improve variable locality.
 945
 946 2001-12-05  Akim Demaille  <akim@epita.fr>
 947
 948         * src/conflicts.c (print_reductions): Pessimize, but clarify.

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

1110         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1111         and YYSTACK_FREE instead of malloc and free.

1129
1130         Instead of mapping the LHS of unused rules to -1, keep the LHS

1167         (union yyalloc): New type.
1168         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1169         an arbitrary restriction on hosts where size_t is wider than int.
1170
1171         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1172         a parser stack overflow.  Allocate just one block of memory for all
1173         three stacks, instead of allocating three blocks; this typically is
1174         faster and reduces fragmentation.
1175
1176         Do not limit the number of items in the stack to a value that fits
1177         in 'int', as this is an arbitrary limit on hosts with 64-bit
1178         size_t and 32-bit int.

1234

1237
1238 2001-11-28  Akim Demaille  <akim@epita.fr>
1239
1240         * src/closure.c (closure): No longer optimize the special case
1241         where all the bits of `ruleset[r]' are set to 0, to make the code

1476         * src/derives.c: Likewise.
1477         * src/reduce.c: (inaccessable_symbols): Using if is better style
1478         than goto.

1506
1507         * src/vcg.c: You do the output, so you are responsible of the
1508         handling of VCG syntax, in particular: use quotearg.
1509         * src/print_graph.c: Don't.
1510         (print_actions): Don't output the actions as part of the nodes,
1511         since that's the job of the edges.

1513         and ask for its output.

1605         * tests/calc.at, tests/output.at, tests/regression.at,
1606         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
1607         now the tests are run in private dirs, therefore AC_CLEANUP and
1608         family can be simplified to 0-ary.
1609         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
1610         use abs. path to find config.h.
1611         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
1612         stderr, there can be way too much random noise.
1613         Instead pass -Werror to GCC and rely on the exit status.

1630         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
1631         Revert a previous patch:  these are really const.
1632         * src/conflicts.c (conflict_report): Additional useless pair of
1633         braces to pacify GCC's warnings for `if () if () {} else {}'.
1634         * src/lex.c (parse_percent_token): Replace equal_offset with
1635         arg_offset.
1636         arg is const.

1638         token_buffer not to change.

1647 2001-11-12  Akim Demaille  <akim@epita.fr>
1648
1649         * src/system.h (ngettext): Now that we use ngettext, be sure to

1734         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
1735         with yyltype/YYLTYPE.  This allows inclusion of the generated

2557
2558         * src/bison.simple (yyparse): Don't take the address of an

2568         completely wrong.

2645         with something new. Skeletons are now processed character by character

2976
2977         * src/reader.c (gensym): `gensym_count' is your own.
2978         Use a static buf to create the symbol name, as token_buffer is no

2980
2981 2001-02-08  Akim Demaille  <akim@epita.fr>
2982
2983         * src/conflicts.c (conflict_report): Be sure not to append to res
2984         between two calls, which could happen if both first sprintf were

2987 2001-02-08  Akim Demaille  <akim@epita.fr>
2988

2990         New, from fileutils 4.0.37.
2991         * configure.in: Require Autoconf 2.49c.  I took some time before
2992         making this decision.  This is the only way out for portability
2993         issues in Bison, it would mean way too much duplicate effort to
2994         import in Bison features implemented in 2.49c since 2.13.
2995         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3003
3004         Get rid of the ad hoc handling of token_buffer in the scanner: use
3005         the obstacks.
3006
3007         * src/lex.c (token_obstack): New.
3008         (init_lex): Initialize it.  No longer call...
3009         (grow_token_buffer): this.  Remove it.

3011

3013
3014         * src/lex.h: Rename all the tokens:
3015         s/\bENDFILE\b/tok_eof/g;
3016         s/\bIDENTIFIER\b/tok_identifier/g;
3017         etc.
3018         Let them be enums, not #define, to ease debugging.
3019         Adjust all the code.
3020
3021 2001-01-18  Akim Demaille  <akim@epita.fr>
3022
3023         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

3025
3026 2001-01-18  Akim Demaille  <akim@epita.fr>
3027
3028         Since we now use obstacks, more % directives can be enabled.
3029
3030         * src/lex.c (percent_table): Also accept `%yacc',
3031         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3032         `%debug'.
3033         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3034         instead of returning a token.
3035         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3036         * src/reader.c (read_declarations): Adjust.
3037         * src/files.c (open_files): Don't call `compute_base_names', don't
3038         compute `attrsfile' since they depend upon data which might be
3039         *in* the input file now.
3040         (output_files): Do it here.
3041         * src/output.c (output_headers): Document the fact that this patch
3042         introduces a guaranteed SEGV for semantic parsers.
3043         * doc/bison.texinfo: Document them.
3044         * tests/suite.at: Exercise these %options.
3045
3046 2000-12-20  Akim Demaille  <akim@epita.fr>
3047
3048         Also handle the output file (--verbose) with obstacks.
3049
3050         * files.c (foutput): Remove.
3051         (output_obstack): New.
3052         Adjust all dependencies.
3053         * src/conflicts.c: Return a string.
3054         * src/system.h (obstack_grow_string): Rename as...
3055         (obstack_sgrow): this.  Be ready to work with non literals.

3059
3060         * src/files.c (open_files): Fix the computation of short_base_name
3061         in the case of `-o foo.tab.c'.
3062
3063 2000-12-20  Akim Demaille  <akim@epita.fr>
3064
3065         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3066         (copy_dollar): Now that everything uses obstacks, get rid of the
3067         FILE * parameters.
3068
3069 2000-12-20  Akim Demaille  <akim@epita.fr>
3070
3071         * src/files.c (open_files): Actually the `.output' file is based
3072         on the short_base_name, not base_name.
3073         * tests/suite.at (Checking output file names): Adjust.
3074
3075 2000-12-20  Akim Demaille  <akim@epita.fr>
3076
3077         * src/bison.s1: Remove, we now use directly...
3078         * src/bison.simple: this.
3079         * src/Makefile.am: Use pkgdata instead of data.
3080

3096         Adjust dependencies.
3097
3098 2000-12-19  Akim Demaille  <akim@epita.fr>
3099
3100         * src/files.c (strsuffix): New.
3101         (stringappend): Be just like strcat but allocate.
3102         (base_names): Eve out from open_files.
3103         Try to simplify the rather hairy computation of base_name and
3104         short_base_name.
3105         (open_files): Use it.
3106         * tests/suite.at (Checking output file names): New test.

3113         `$'.

3115         * src/bison.hairy: Likewise.
3116
3117 2000-12-19  Akim Demaille  <akim@epita.fr>
3118
3119         * src/output.c (output_parser): Compute the `#line' lines when
3120         there are.
3121         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3122         Suggested by Hans Aberg.
3123
3124 2000-12-19  Akim Demaille  <akim@epita.fr>
3125
3126         Let the handling of the skeleton files be local to the procedures
3127         that use it.
3128
3129         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

3145
3146         * src/files.c (open_files): Yipee!  We no longer need all the code
3147         looking for `/tmp' since we have no tmp file.
3148
3149 2000-12-19  Akim Demaille  <akim@epita.fr>
3150

3161         `timestamp' and `text' in the default YYLTYPE.

3164
3165         * src/reader.c (copy_definition, parse_union_decl, copy_action)
3166         (copy_guard): Quote the file names.
3167         Reported by Laurent Mascherpa.

3177
3178         * lib/obstack.h: Formatting changes.
3179         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3180         prevents type checking.
3181         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3182         cast the value to (void *): assigning a `foo *' to a `void *'
3183         variable is valid.
3184         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

3218         defining.
3219         * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
3220
3221 2000-11-07  Akim Demaille  <akim@epita.fr>
3222
3223         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3224         Merge in a single CPP if/else.
3225
3226 2000-11-07  Akim Demaille  <akim@epita.fr>
3227
3228         * src/output.c (output): Remove useless variables.
3229         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3230         argument `data' for consistency with the prototypes.
3231         Qualify it `const'.
3232         (obstack_copy, obstack_copy0): Rename the second argument as
3233         `address' for consistency.  Qualify it `const'.

3235         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
3236         `const' their input argument (`data' or `address').

3248
3249         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3265         * src/main.c (main): Don't use `atexit' to register `done', since
3266         it no longer has to remove tmp files, just call `output_files'
3267         when there are no errors.

3372         When a literal string is used to define two different tokens,
3373         `bison -v' segfaults.
3374         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3375
3376         * tests/regression.m4: New file.
3377         Include the core of the sample provided by Piotr Gackiewicz.
3378         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3379         properly.
3380
3381 2000-10-04  Akim Demaille  <akim@epita.fr>
3382
3383         * src/reader.c (parse_expect_decl): Keep `count' within the size
3384         of `buffer'.
3385         From Neil Booth.
3386
3387 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3388
3389         * bison.s1 (yyparse): Assign the default value
3390         unconditionally, to avoid a GCC warning and make the parser a
3391         tad smaller.
3392
3393 2000-10-02  Akim Demaille  <akim@epita.fr>
3394
3395         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3396         options.
3397
3398 2000-10-02  Akim Demaille  <akim@epita.fr>
3399
3400         * src/derives.c, src/print.c, src/reduce.c: To ease the
3401         translation, move some `\n' out of the translated strings.
3402
3403 2000-10-02  Akim Demaille  <akim@epita.fr>
3404
3405         The location tracking mechanism is precious for parse error
3406         messages.  Nevertheless, it is enabled only when `@n' is used in
3407         the grammar, which is a different issue (you can use it in error
3408         message, but not in the grammar per se).  Therefore, there should
3409         be another means to enable it.
3410
3411         * src/getargs.c (getargs): Support `--locations'.
3412         (usage): Report it.
3413         * src/getargs.h (locationsflag): Export it.
3414         * src/lex.c (percent_table): Support `%locations'.
3415         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3416         with `locationsflag'.
3417         * doc/bison.texinfo: Document `--locations' and `%locations'.
3418         Sort the options.
3419         * tests/calc.m4: Test it.
3420
3421         For regularity of the names, replace each
3422         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3423         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3424         In addition replace each `flag' with `_flag'.
3425
3426 2000-10-02  Akim Demaille  <akim@epita.fr>
3427
3428         Also test parse error messages, including with YYERROR_VERBOSE.
3429
3430         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3431         associative).
3432         Use it to check the computations.
3433         Use it to check `nonassoc' is honored.
3434         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3435         `--yyerror-verbose'.
3436         (_AT_CHECK_CALC): Adjust to this option.
3437         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3438
3439 2000-10-02  Akim Demaille  <akim@epita.fr>
3440
3441         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3442         the latter demonstrates a flaw in the handling of non debugging
3443         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3444         was used in order to simplify:
3445
3446         #if YYDEBUG
3447         if (yydebug)
3448         {
3449         ...
3450         }
3451         #endif
3452
3453         into
3454
3455         if (yydebug)
3456         {
3457         ...
3458         }
3459
3460         unfortunately this leads to a CPP conflict when
3461         `--name-prefix=foo' is used since it produces `#define yydebug
3462         foodebug'.
3463
3464         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3465         (YYDPRINTF): New macro.
3466         Spread its use.
3467         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3468         the bison options.
3469         Also test `--verbose', `--defines' and `--name-prefix'.
3470
3471 2000-10-02  Akim Demaille  <akim@epita.fr>
3472
3473         Improve the readability of the produced parsers.
3474
3475         * src/bison.s1: Formatting changes.
3476         Improve the comment related to the `$' mark.
3477         (yydefault): Don't fall through to `yyresume': `goto' there.
3478         * src/output.c (output_parser): When the `$' is met, skip the end
3479         of its line.
3480         New variable, `number_of_dollar_signs', to check there's exactly
3481         one `$' in the parser skeleton.
3482
3483 2000-10-02  Akim Demaille  <akim@epita.fr>
3484
3485         * lib/xstrdup.c: New file, from the fileutils.
3486         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3487         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3488         instead of strlen + xmalloc + strcpy.
3489         * src/symtab.c (copys): Remove, use xstrdup instead.
3490
3491 2000-10-02  Akim Demaille  <akim@epita.fr>
3492
3493         * src/gram.h (associativity): New enum type which replaces the
3494         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3495         `right_assoc', `left_assoc' and `non_assoc'.
3496         Adjust all dependencies.
3497         * src/reader.c: Formatting changes.
3498         (LTYPESTR): Don't define it, use it as a literal in
3499         `reader_output_yylsp'.
3500         * src/symtab.h (symbol_class): New enum type which replaces the
3501         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3502         `sunknown', `stoken and `snterm'.
3503
3504 2000-10-02  Akim Demaille  <akim@epita.fr>
3505
3506         * src/getargs.c (fixed_outfiles): Rename as...
3507         (yaccflag): for consistency and accuracy.
3508         Adjust dependencies.
3509
3510 2000-10-02  Akim Demaille  <akim@epita.fr>
3511
3512         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3513         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3514         difficult and introduced a lot of core dump.  It turns out that
3515         Bison used an implementation of `xmalloc' based on `calloc', and
3516         at various places it does depend upon the initialization to 0.  I
3517         have not tried to isolate the pertinent places, and all the former
3518         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3519         someone should address this issue.
3520
3521         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3522         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

3528 2000-10-02  Akim Demaille  <akim@epita.fr>
3529
3530         Various anti-`extern in *.c' changes.
3531
3532         * src/system.h: Include `assert.h'.
3533
3534 2000-10-02  Akim Demaille  <akim@epita.fr>
3535
3536         * src/state.h (nstates, final_state, first_state, first_shift)
3537         (first_reduction): Move their exportation from here...
3538         * src/LR0.h: to here.
3539         Adjust dependencies.
3540         * src/getargs.c (statisticsflag): New variable.
3541         Add support for `--statistics'.

3608 2000-10-02  Akim Demaille  <akim@epita.fr>
3609
3610         * src/lalr.h: New file.

3613
3614 2000-10-02  Akim Demaille  <akim@epita.fr>
3615
3616         * src/output.c (token_actions): Introduce a temporary array,
3617         YYDEFACT, that makes it possible for this function to use
3618         output_short_table.
3619
3620 2000-10-02  Akim Demaille  <akim@epita.fr>
3621
3622         `user_toknums' is output as a `short[]' in `output.c', while it is
3623         defined as a `int[]' in `reader.c'.  For consistency with the
3624         other output tables, `user_toknums' is now defined as a table of
3625         shorts.
3626
3627         * src/reader.c (user_toknums): Be a short table instead of an int
3628         table.
3629         Adjust dependencies.
3630
3631         Factor the short table outputs.
3632
3633         * src/output.c (output_short_table): New function.
3634         * src/output.c (output_gram, output_stos, output_rule_data)

3636
3637 2000-10-02  Akim Demaille  <akim@epita.fr>
3638
3639         * src/output.c (output): Topological sort of the functions, in
3640         order to get rid of the `static' prototypes.
3641         No longer use `register'.
3642         * src/output.h: New file.
3643         Propagate its inclusion in files explicitly prototyping functions
3644         from output.c.

3656         (new_closure, free_closure): these.  Adjust dependencies.
3657         * src/LR0.c: Formatting changes, topological sort, use of
3658         cloture.h.

3666         inclusion.
3667         Don't define PARAMS.
3668         * src/system.h: Define PARAMS.
3669         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3670         purpose of config.h.  system.h must not try to fix wrong
3671         definitions in config.h.

3685         Use these macros to test bison with options `', `--raw',
3686         `--debug', `--yacc', `--yacc --debug'.
3687
3688 2000-09-19  Akim Demaille  <akim@epita.fr>
3689
3690         * src/output.c: Formatting changes.

3751 2000-04-14  Akim Demaille  <akim@epita.fr>
3752
3753         * src/reader.c (copy_comment2): New function, same as former

3808         * configure.in: Adjust.
3809         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

3833         the file name, not the whole `#line LINE FILE'.
3834
3835 2000-03-17  Akim Demaille  <akim@epita.fr>
3836
3837         On syntax errors, report the token on which we choked.
3838
3839         * src/bison.s1 (yyparse): In the label yyerrlab, when

3857
3858         * src/reader.c (copy_definition): Use copy_string and
3859         copy_comment.  Removed now unused `match', `ended',
3860         `cplus_comment'.
3861         (copy_comment, copy_string): Moved, to be visible from
3862         copy_definition.
3863
3864 2000-03-17  Akim Demaille  <akim@epita.fr>
3865
3866         * src/reader.c (copy_string): Declare `static inline'.  No

3888
3889         Change the handling of @s so that they behave exactly like $s.
3890         There is now a pseudo variable @$ (readble and writable), location
3891         of the lhs of the rule (by default ranging from the location of
3892         the first symbol of the rhs, to the location of the last symbol,
3893         or, if the rhs is empty, YYLLOC).
3894
3895         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3896         yyval.
3897         (yyparse): When providing a default semantic action, provide a
3898         default location action.
3899         (after the $): No longer change `*YYLSP', just stack YYLOC the
3900         same way you stack YYVAL.
3901         * src/reader.c (read_declarations): Use warns.
3902         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3903         (copy_action, case '@'): Likewise.
3904         Use a standard error message, to save useless work from
3905         translators.
3906
3907 2000-03-17  Akim Demaille  <akim@epita.fr>
3908

3916         Makefile now handles them.
3917
3918 2000-03-16  Akim Demaille  <akim@epita.fr>
3919

3926
3927         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
3928         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3929         One `#if YYDEBUG' remains, since it uses variables which are
3930         defined only if `YYDEBUG != 0'.
3931
3932 2000-03-16  Akim Demaille  <akim@epita.fr>
3933
3934         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
3935         and related variables so that the similarities are highlighted.

3955         * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
3956         handled via src/Makefile.am.
3957         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
