ChangeLog

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

 359
 360         Reductions in web2c.y are improperly reported.
 361         Reported by Mike Castle.
 362
 363         * src/conflicts.c (print_reductions): Fix.
 364         * tests/regression.at (Web2c): New.
 365
 366 2001-12-18  Akim Demaille  <akim@epita.fr>
 367
 368         Some host fail on `assert (!"foo")', which expands to
 369         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 370         Reported by Nelson Beebee.
 371
 372         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 373         `#define it_succeeded 0' and `assert (it_succeeded)'.
 374
 375 2001-12-17  Marc Autret  <autret_m@epita.fr>
 376
 377         * src/bison.simple: Don't hard code the skeleton line and filename.
 378         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 379         New line counter 'skeleton_line' (skeleton-line muscle).
 380
 381 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 382
 383         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 384         YYDEBUG must be defined to a nonzero value.
 385
 386         * src/bison.simple (yytname): Do not assume that the user defines
 387         YYDEBUG to a properly parenthesized expression.
 388
 389 2001-12-17  Akim Demaille  <akim@epita.fr>
 390
 391         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 392         nlookaheads is a new member.
 393         Adjust all users.
 394         * src/lalr.h (nlookaheads): Remove this orphan declaration.
 395         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 396         state.
 397
 398 2001-12-17  Akim Demaille  <akim@epita.fr>
 399
 400         * src/files.h, src/files.c (open_files, close_files): Remove.
 401         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 402         let...
 403         * src/reader.c (reader): Do it.
 404
 405 2001-12-17  Akim Demaille  <akim@epita.fr>
 406
 407         * src/conflicts.c (print_reductions): Formatting changes.
 408
 409 2001-12-17  Akim Demaille  <akim@epita.fr>
 410
 411         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 412         (flush_reduce): New.
 413         (resolve_sr_conflict): Adjust.
 414
 415 2001-12-17  Akim Demaille  <akim@epita.fr>
 416
 417         * src/output.c (output_obstack): Be static and rename as...
 418         (format_obstack): this, to avoid any confusion with files.c's
 419         output_obstack.
 420         * src/reader.h (muscle_obstack): Move to...
 421         * src/output.h: here, since it's defined in output.c.
 422
 423 2001-12-17  Akim Demaille  <akim@epita.fr>
 424
 425         * src/output.c (action_row, save_column, default_goto)
 426         (sort_actions, matching_state, pack_vector): Better variable
 427         locality.
 428
 429 2001-12-17  Akim Demaille  <akim@epita.fr>
 430
 431         * src/output.c: Various formatting changes.
 432
 433 2001-12-17  Akim Demaille  <akim@epita.fr>
 434
 435         * src/files.c (output_files): Free the output_obstack.
 436         * src/main.c (main): Call print and print_graph conditionally.
 437         * src/print.c (print): Work unconditionally.
 438         * src/print_graph.c (print_graph): Work unconditionally.
 439         * src/conflicts.c (log_resolution): Output only if verbose_flag.
 440
 441 2001-12-16  Marc Autret  <autret_m@epita.fr>
 442
 443         * src/output.c (actions_output): Fix. When we use %no-lines,
 444         there is one less line per action.
 445
 446 2001-12-16  Marc Autret  <autret_m@epita.fr>
 447
 448         * src/bison.simple: Remove a useless #line directive.
 449         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 450         * src/output.c (get_lines_number): New.
 451         (output_parser): Adjust, now takes care about the lines of a
 452         output muscles.
 453         Fix line numbering.
 454         (actions_output): Computes the number of lines taken by actions.
 455         (output_master_parser): Insert new skeleton which is the name of
 456         the output parser file name.
 457
 458 2001-12-15  Marc Autret  <autret_m@epita.fr>
 459
 460         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
 461
 462 2001-12-15  Marc Autret  <autret_m@epita.fr>
 463
 464         * src/output.c (output_gram): Keep track of the hairy one.
 465
 466 2001-12-15  Akim Demaille  <akim@epita.fr>
 467
 468         Make `make distcheck' work.
 469
 470         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 471         system.h which uses libgettext.h.
 472
 473 2001-12-15  Akim Demaille  <akim@epita.fr>
 474
 475         * src/nullable.c (set_nullable): Useless rules must be skipped,
 476         otherwise, since we range over their symbols, we might look at a
 477         nonterminal which no longer ``exists'', i.e., it is not counted in
 478         `nvars', hence we overflow our arrays.
 479
 480 2001-12-15  Akim Demaille  <akim@epita.fr>
 481
 482         The header can also be produced directly, without any obstack!
 483         Yahoo!
 484
 485         * src/files.c, src/files.h (defines_obstack): Remove.
 486         (compute_header_macro): Global.
 487         (defines_obstack_save): Remove.
 488         * src/reader.c (parse_union_decl): No longer output to
 489         defines_obstack: its content can be found in the `stype' muscle
 490         anyway.
 491         (output_token_translations): Merge into...
 492         (symbols_output): this.
 493         Rename as...
 494         (symbols_save): this.
 495         (reader): Adjust.
 496         * src/output.c (header_output): New.
 497         (output): Call it.
 498
 499 2001-12-15  Akim Demaille  <akim@epita.fr>
 500
 501         * src/reader.c (parse_union_decl): Instead of handling two obstack
 502         simultaneously, use one to define the `stype' muscle, and use the
 503         value of the latter to fill defines_obstack.
 504         (copy_comment): Remove.
 505         (copy_comment2): Work for a single obstack.
 506         Rename as...
 507         (copy_comment): this.
 508
 509 2001-12-15  Akim Demaille  <akim@epita.fr>
 510
 511         * src/lex.c, src/lex.h (xgetc): No longer static.
 512         * src/reader.c (parse_union_decl): Revamp.
 513
 514 2001-12-15  Akim Demaille  <akim@epita.fr>
 515
 516         Still making progress in separating Bison into (i) input, (ii)
 517         process, (iii) output: now we can directly output the parser file
 518         without using table_obstack at all.
 519
 520         * src/files.c, src/files.h (table_obstack): Bye bye.
 521         (parser_file_name): New.
 522         * src/files.c (compute_output_file_names): Compute it.
 523         * src/output.c (actions_output, output_parser)
 524         (output_master_parser): To a file instead of an obstack.
 525
 526 2001-12-15  Akim Demaille  <akim@epita.fr>
 527
 528         Attach actions to rules, instead of pre-outputting them to
 529         actions_obstack.
 530
 531         * src/gram.h (rule_t): action and action_line are new members.
 532         * src/reader.c (symbol_list): Likewise.
 533         (copy_action): Save the actions within the rule.
 534         (packgram): Save them in rule_table.
 535         * src/output.c (actions_output): New.
 536         (output_parser): Use it on `%%actions'.
 537         (output_rule_data): Don't free rule_table.
 538         (output): Do it.
 539         (prepare): Don't save the `action' muscle.
 540         * src/bison.simple: s/%%action/%%actions/.
 541
 542 2001-12-15  Akim Demaille  <akim@epita.fr>
 543
 544         * src/reader.c (copy_action): When --yacc, don't append a `;'
 545         to the user action: let it fail if lacking.
 546         Suggested by Arnold Robbins and Tom Tromey.
 547
 548 2001-12-14  Akim Demaille  <akim@epita.fr>
 549
 550         * src/lex.c (literalchar): Simply return the char you decoded, non
 551         longer mess around with obstacks and int pointers.
 552         Adjust all callers.
 553
 554 2001-12-14  Akim Demaille  <akim@epita.fr>
 555
 556         * src/lex.c (literalchar): Don't escape the special characters,
 557         just decode them, and keep them as char (before, eol was output as
 558         the 2 char string `\n' etc.).
 559         * src/output.c (output_rule_data): Use quotearg to output the
 560         token strings.
 561
 562 2001-12-13  Paul Eggert  <eggert@twinsun.com>
 563
 564         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
 565         Do not infringe on the global user namespace when using C++.
 566         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
 567         All uses of `fprintf' and `stderr' changed.
 568
 569         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
 570
 571 2001-12-13  Akim Demaille  <akim@epita.fr>
 572
 573         The computation of nullable is broken: it doesn't handle empty
 574         RHS's properly.
 575
 576         * tests/torture.at (GNU AWK Grammar): New.
 577         * tests/sets.at (Nullable): New.
 578         * src/nullable.c (set_nullable): Instead of blindly looping over
 579         `ritems', loop over the rules, and then over their rhs's.
 580
 581         Work around Autotest bugs.
 582
 583         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
 584         frame, because Autotest understand lines starting with a `+' as
 585         traces from the shell.  Then, they are not processed properly.
 586         Admittedly an Autotest bug, but we don't have time to wait for
 587         Autotest to catch up.
 588         * tests/regression.at (Broken Closure): Adjust to the new table
 589         frames.
 590         Move to...
 591         * tests/sets.at: here.
 592
 593 2001-12-13  Akim Demaille  <akim@epita.fr>
 594
 595         * src/closure.c (closure): Use nrules instead of playing tricks
 596         with BITS_PER_WORD.
 597
 598 2001-12-13  Akim Demaille  <akim@epita.fr>
 599
 600         * src/print.c (print_actions): Output the handling of `$' as the
 601         traces do: shifting the token EOF.  Before EOF was treated as a
 602         nonterminal.
 603         * tests/regression.at: Adjust some tests.
 604         * src/print_graph.c (print_core): Complete the set of items via
 605         closure.  The next-to-final and final states are still unsatisfying,
 606         but that's to be addressed elsewhere.
 607         No longer output the rule numbers, but do output the state number.
 608         A single loop for the shifts + gotos is enough, but picked a
 609         distinct color for each.
 610         (print_graph): Initialize and finalize closure.
 611
 612 2001-12-13  Akim Demaille  <akim@epita.fr>
 613
 614         * src/reader.c (readgram): Remove dead code, an strip useless
 615         braces.
 616         (get_type): Remove, unused.
 617
 618 2001-12-12  Akim Demaille  <akim@epita.fr>
 619
 620         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 621         on that of lib/error.c.
 622
 623 2001-12-12  Akim Demaille  <akim@epita.fr>
 624
 625         Some hosts don't like `/' in includes.
 626
 627         * src/system.h: Include libgettext.h without qualifying the path.
 628         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 629         $(top_srcdir).
 630
 631 2001-12-11  Marc Autret  <autret_m@epita.fr>
 632
 633         * src/output.c (output_parser): Remove useless muscle.
 634
 635 2001-12-11  Marc Autret  <autret_m@epita.fr>
 636
 637         * src/bison.simple: Remove #line just before %%epilogue. It
 638         is now handled in ...
 639         * src/reader.c (read_additionnal_code): Add the output of a
 640         #line for the epilogue.
 641
 642 2001-12-10  Marc Autret  <autret_m@epita.fr>
 643
 644         * src/reader.c (copy_definition): Re-use CPP-outed code which
 645         replace precedent remove.
 646         * src/bison.simple: Remove #line before %%prologue because
 647         %%input-line is wrong at this time.
 648
 649 2001-12-10  Marc Autret  <autret_m@epita.fr>
 650
 651         * src/reader.c (symbols_output): Clean up.
 652         * src/output.c (output_gram, output): Clean up.
 653
 654 2001-12-10  Akim Demaille  <akim@epita.fr>
 655
 656         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 657         * src/LR0.c (set_state_table): here.
 658         * src/lalr.c (lalr): Call it.
 659
 660 2001-12-10  Akim Demaille  <akim@epita.fr>
 661
 662         * src/state.h (shifts): Remove the `number' member: shifts are
 663         attached to state, hence no longer need to be labelled with a
 664         state number.
 665
 666 2001-12-10  Akim Demaille  <akim@epita.fr>
 667
 668         Now that states have a complete set of members, the linked list of
 669         shifts is useless: just fill directly the state's shifts member.
 670
 671         * src/state.h (shifts): Remove the `next' member.
 672         * src/LR0.c (first_state, last_state): Remove.
 673         Adjust the callers.
 674         (augment_automaton): Don't look for the shifts that must be added
 675         a shift on EOF: it is those of the state we looked for!  But now,
 676         since shifts are attached, it is no longer needed to looking
 677         merely by its id: its number.
 678
 679 2001-12-10  Akim Demaille  <akim@epita.fr>
 680
 681         * src/LR0.c (augment_automaton): Better variable locality.
 682         Remove an impossible branch: if there is a state corresponding to
 683         the start symbol being shifted, then there is shift for the start
 684         symbol from the initial state.
 685
 686 2001-12-10  Akim Demaille  <akim@epita.fr>
 687
 688         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 689         only when appropriate: when insert_start_shifting_state' is not
 690         invoked.
 691         * tests/regression.at (Rule Line Numbers): Adjust.
 692
 693 2001-12-10  Akim Demaille  <akim@epita.fr>
 694
 695         * src/LR0.c (augment_automaton): Now that all states have shifts,
 696         merge the two cases addition shifts to the initial state.
 697
 698 2001-12-10  Akim Demaille  <akim@epita.fr>
 699
 700         * src/lalr.c (set_state_table): Move to...
 701         * src/LR0.c: here.
 702         * src/lalr.c (lalr): Don't call it...
 703         * src/LR0.c (generate_states): do it.
 704         * src/LR0.h (first_state): Remove, only the table is used.
 705
 706 2001-12-10  Akim Demaille  <akim@epita.fr>
 707
 708         * src/LR0.h (first_shift, first_reduction): Remove.
 709         * src/lalr.c: Don't use first_shift: find shifts through the
 710         states.
 711
 712 2001-12-10  Akim Demaille  <akim@epita.fr>
 713
 714         * src/LR0.c: Attach shifts to states as soon as they are
 715         computed.
 716         * src/lalr.c (set_state_table): Instead of assigning shifts to
 717         state, just assert that the mapping was properly done.
 718
 719 2001-12-10  Akim Demaille  <akim@epita.fr>
 720
 721         * src/LR0.c (insert_start_shift): Rename as...
 722         (insert_start_shifting_state): this.
 723         (insert_eof_shifting_state, insert_accepting_state): New.
 724         (augment_automaton): Adjust.
 725         Better locality of the variables.
 726         When looking if the start_symbol is shifted from the initial
 727         state, using `while (... symbol != start_symbol ...)' sounds
 728         better than `while (... symbol < start_symbol ...)': If fail
 729         to see how the order between symbols could be relevant!
 730
 731 2001-12-10  Akim Demaille  <akim@epita.fr>
 732
 733         * src/getargs.h: Don't declare `spec_name_prefix' and
 734         `spec_file_prefix', declared by src/files.h.
 735         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 736         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 737         * src/output.c (prepare): Adjust.
 738         * src/reader.c (symbols_output): Likewise.
 739         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 740
 741 2001-12-10  Akim Demaille  <akim@epita.fr>
 742
 743         * src/muscle_tab.c (muscle_init): NULL is a better default than
 744         `"0"'.
 745
 746 2001-12-10  Akim Demaille  <akim@epita.fr>
 747
 748         * src/reader.c (reader): Calling symbols_output once is enough.
 749
 750 2001-12-10  Akim Demaille  <akim@epita.fr>
 751
 752         Now that states have a complete set of members, the linked list of
 753         reductions is useless: just fill directly the state's reductions
 754         member.
 755
 756         * src/state.h (struct reductions): Remove member `number' and
 757         `next'.
 758         * src/LR0.c (first_reduction, last_reduction): Remove.
 759         (save_reductions): Don't link the new reductions, store them in
 760         this_state.
 761         * src/lalr.c (set_state_table): No need to attach reductions to
 762         states, it's already done.
 763         * src/output.c (output_actions): No longer free the shifts, then
 764         the reductions, then the states: free all the states and their
 765         members.
 766
 767 2001-12-10  Akim Demaille  <akim@epita.fr>
 768
 769         * src/options.c (OPTN, DRTV, BOTH): New.
 770         (option_table): Use them.
 771
 772         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 773         the job of system.h.
 774         * src/options.c: Don't include stdio.h and xalloc.h for the same
 775         reasons.
 776
 777 2001-12-10  Akim Demaille  <akim@epita.fr>
 778
 779         * src/output.c (output, prepare): Make sure the values of the
 780         muscles `action' and `prologue' are 0-terminated.
 781
 782 2001-12-10  Akim Demaille  <akim@epita.fr>
 783
 784         Clean up GCC warnings.
 785
 786         * src/reader.c (copy_action): `buf' is not used.
 787         (parse_skel_decl): Be static.
 788         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 789         * src/options.h (create_long_option_table): Have a real prototype.
 790         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 791         (hash_delete_at): Return const void *.
 792         Adjust casts to preserve the const.
 793
 794 2001-12-10  Akim Demaille  <akim@epita.fr>
 795
 796         * configure.in: Require 2.52g.
 797         M4 is not needed, but AUTOM4TE is.
 798         * m4/m4.m4: Remove.
 799         * tests/Makefile.am: Adjust.
 800
 801 2001-12-10  Akim Demaille  <akim@epita.fr>
 802
 803         One structure for states is enough, even though theoretically
 804         there are LR(0) states and LALR(1) states.
 805
 806         * src/lalr.h (state_t): Remove.
 807         (state_table): Be state_t **, not state_t *.
 808         * src/state.h (core, CORE_ALLOC): Rename as...
 809         (state_t, STATE_ALLOC): this.
 810         Add the LALR(1) members: shifts, reductions, errs.
 811         * src/LR0.c (state_table): Rename as...
 812         (state_hash): this, to avoid name clashes with the global
 813         `state_table'.
 814         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 815         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 816
 817 2001-12-10  Akim Demaille  <akim@epita.fr>
 818
 819         Bison dumps core on bash.y.
 820         Reported by Pascal Bart.
 821
 822         * src/warshall.c (bitmatrix_print): New.
 823         (TC): Use it.
 824         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 825         j must be the outer loop.
 826         * tests/regression.at (Broken Closure): New.
 827
 828 2001-12-05  Akim Demaille  <akim@epita.fr>
 829
 830         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 831         its argument.
 832         Reported by Peter Hámorský.
 833
 834 2001-12-05  Akim Demaille  <akim@epita.fr>
 835
 836         * src/conflicts.c (err_table): Remove.
 837         (resolve_sr_conflict): Adjust.
 838         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 839         Rename as...
 840         (state_t.reductions, state_t.shifts): this.
 841
 842 2001-12-05  Akim Demaille  <akim@epita.fr>
 843
 844         * src/reduce.c (reduce_grammar_tables): No longer disable the
 845         removal of useless rules via CPP but via `if (0)', so that the
 846         compiler still check the code is valid.
 847         For instance, it should have noticed `rline' no longer exists: use
 848         the `line' member of rule_t.
 849         * src/gram.c (dummy, rline): Remove, unused.
 850
 851 2001-12-05  Akim Demaille  <akim@epita.fr>
 852
 853         * src/output.c (pack_vector): Use assert, not berror.
 854         * src/main.c (berror): Remove, unused.
 855
 856 2001-12-05  Akim Demaille  <akim@epita.fr>
 857
 858         New experimental feature: if --verbose --trace output all the
 859         items of a state, not only its kernel.
 860
 861         * src/print.c (print_core): If `trace_flag', then invoke closure
 862         before outputting the items of the state (print_core is no longer
 863         a correct name them).
 864         (print_results): Invoke new_closure/free_closure if needed.
 865
 866 2001-12-05  Akim Demaille  <akim@epita.fr>
 867
 868         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 869         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 870         (nitemset): for consistency with the rest of the project.
 871
 872 2001-12-05  Akim Demaille  <akim@epita.fr>
 873
 874         * src/closure.c (print_closure): Improve.
 875         (closure): Use it for printing input and output.
 876
 877 2001-12-05  Akim Demaille  <akim@epita.fr>
 878
 879         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 880         indexed by nonterminals.
 881
 882 2001-12-05  Akim Demaille  <akim@epita.fr>
 883
 884         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 885         what it was!).
 886         * src/warshall.h: Remove accidental duplication of the content.
 887
 888 2001-12-05  Akim Demaille  <akim@epita.fr>
 889
 890         * src/closure.c (set_fderives): De-obfuscate.
 891
 892 2001-12-05  Akim Demaille  <akim@epita.fr>
 893
 894         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
 895
 896 2001-12-05  Akim Demaille  <akim@epita.fr>
 897
 898         * src/closure.c (set_firsts): De-obfuscate.
 899
 900 2001-12-05  Akim Demaille  <akim@epita.fr>
 901
 902         * src/output.c (action_row): De-obfuscate
 903         using the good o' techniques: arrays not pointers, variable
 904         locality, BITISSET, RESETBIT etc.
 905
 906 2001-12-05  Akim Demaille  <akim@epita.fr>
 907
 908         Pessimize the code to simplify it: from now on, all the states
 909         have a valid SHIFTS, which NSHIFTS is possibly 0.
 910
 911         * src/LR0.c (shifts_new): Be global and move to..
 912         * src/state.c, src/state.h: here.
 913         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 914         * src/print_graph: Adjust.
 915
 916 2001-12-05  Akim Demaille  <akim@epita.fr>
 917
 918         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 919         * src/conflicts.c: Use it.
 920         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 921         incorrectly ``simplified''.
 922
 923 2001-12-05  Akim Demaille  <akim@epita.fr>
 924
 925         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
 926         using the good o' techniques: arrays not pointers, variable
 927         locality, BITISSET, RESETBIT etc.
 928
 929 2001-12-05  Akim Demaille  <akim@epita.fr>
 930
 931         * src/state.h (SHIFT_SYMBOL): New.
 932         * src/conflicts.c: Use it to deobfuscate.
 933
 934 2001-12-05  Akim Demaille  <akim@epita.fr>
 935
 936         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
 937         (print_reductions): De-obfuscate using the good o' techniques:
 938         arrays not pointers, variable locality, BITISSET.
 939
 940 2001-12-05  Akim Demaille  <akim@epita.fr>
 941
 942         * src/conflicts.c (print_reductions): Arrays, not pointers.
 943         Use BITISSET.
 944
 945 2001-12-05  Akim Demaille  <akim@epita.fr>
 946
 947         * src/conflicts.c (print_reductions): Pessimize, but clarify.
 948
 949 2001-12-05  Akim Demaille  <akim@epita.fr>
 950
 951         * src/conflicts.c (print_reductions): Improve variable locality.
 952
 953 2001-12-05  Akim Demaille  <akim@epita.fr>
 954
 955         * src/conflicts.c (print_reductions): Pessimize, but clarify.

 957 2001-12-05  Akim Demaille  <akim@epita.fr>
 958

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

1174         (union yyalloc): New type.
1175         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1176         an arbitrary restriction on hosts where size_t is wider than int.
1177
1178         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1179         a parser stack overflow.  Allocate just one block of memory for all
1180         three stacks, instead of allocating three blocks; this typically is
1181         faster and reduces fragmentation.
1182
1183         Do not limit the number of items in the stack to a value that fits
1184         in 'int', as this is an arbitrary limit on hosts with 64-bit
1185         size_t and 32-bit int.
1186
1187 2001-11-29  Marc Autret  <autret_m@epita.fr>

1244
1245 2001-11-28  Akim Demaille  <akim@epita.fr>
1246
1247         * src/closure.c (closure): No longer optimize the special case
1248         where all the bits of `ruleset[r]' are set to 0, to make the code

1483         * src/derives.c: Likewise.
1484         * src/reduce.c: (inaccessable_symbols): Using if is better style

1513
1514         * src/vcg.c: You do the output, so you are responsible of the

1517         (print_actions): Don't output the actions as part of the nodes,
1518         since that's the job of the edges.

1612         * tests/calc.at, tests/output.at, tests/regression.at,
1613         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
1614         now the tests are run in private dirs, therefore AC_CLEANUP and
1615         family can be simplified to 0-ary.
1616         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
1617         use abs. path to find config.h.
1618         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

1642         arg_offset.
1643         arg is const.

1645         token_buffer not to change.

2564
2565         * src/bison.simple (yyparse): Don't take the address of an

2575         completely wrong.

2614         bound to true.
2615         (read_declarations): Add case for macro definition.
2616         (copy_identifier): New.
2617         (parse_macro_decl): Read macro identifiers using copy_identifier

2652         with something new. Skeletons are now processed character by character

2654         first step in making Bison's output process (a lot) more flexible.

2983
2984         * src/reader.c (gensym): `gensym_count' is your own.
2985         Use a static buf to create the symbol name, as token_buffer is no

2989
2990         * src/conflicts.c (conflict_report): Be sure not to append to res
2991         between two calls, which could happen if both first sprintf were

2997         New, from fileutils 4.0.37.
2998         * configure.in: Require Autoconf 2.49c.  I took some time before
2999         making this decision.  This is the only way out for portability
3000         issues in Bison, it would mean way too much duplicate effort to
3001         import in Bison features implemented in 2.49c since 2.13.
3002         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3013
3014         * src/lex.c (token_obstack): New.
3015         (init_lex): Initialize it.  No longer call...

3020
3021         * src/lex.h: Rename all the tokens:
3022         s/\bENDFILE\b/tok_eof/g;
3023         s/\bIDENTIFIER\b/tok_identifier/g;
3024         etc.
3025         Let them be enums, not #define, to ease debugging.
3026         Adjust all the code.
3027
3028 2001-01-18  Akim Demaille  <akim@epita.fr>
3029
3030         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

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

3057         * files.c (foutput): Remove.
3058         (output_obstack): New.

3062         (obstack_sgrow): this.  Be ready to work with non literals.

3067         * src/files.c (open_files): Fix the computation of short_base_name
3068         in the case of `-o foo.tab.c'.
3069
3070 2000-12-20  Akim Demaille  <akim@epita.fr>
3071
3072         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3073         (copy_dollar): Now that everything uses obstacks, get rid of the
3074         FILE * parameters.
3075
3076 2000-12-20  Akim Demaille  <akim@epita.fr>
3077
3078         * src/files.c (open_files): Actually the `.output' file is based
3079         on the short_base_name, not base_name.
3080         * tests/suite.at (Checking output file names): Adjust.
3081
3082 2000-12-20  Akim Demaille  <akim@epita.fr>
3083
3084         * src/bison.s1: Remove, we now use directly...
3085         * src/bison.simple: this.
3086         * src/Makefile.am: Use pkgdata instead of data.

3101         (output_files): Adjust.
3102         (base_name, short_base_name): Be global.
3103         Adjust dependencies.
3104
3105 2000-12-19  Akim Demaille  <akim@epita.fr>
3106
3107         * src/files.c (strsuffix): New.
3108         (stringappend): Be just like strcat but allocate.
3109         (base_names): Eve out from open_files.
3110         Try to simplify the rather hairy computation of base_name and
3111         short_base_name.
3112         (open_files): Use it.
3113         * tests/suite.at (Checking output file names): New test.

3123
3124 2000-12-19  Akim Demaille  <akim@epita.fr>
3125
3126         * src/output.c (output_parser): Compute the `#line' lines when
3127         there are.
3128         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3129         Suggested by Hans Aberg.
3130
3131 2000-12-19  Akim Demaille  <akim@epita.fr>
3132
3133         Let the handling of the skeleton files be local to the procedures
3134         that use it.
3135
3136         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

3152
3153         * src/files.c (open_files): Yipee!  We no longer need all the code
3154         looking for `/tmp' since we have no tmp file.
3155
3156 2000-12-19  Akim Demaille  <akim@epita.fr>

3171
3172         * src/reader.c (copy_definition, parse_union_decl, copy_action)
3173         (copy_guard): Quote the file names.
3174         Reported by Laurent Mascherpa.

3184
3185         * lib/obstack.h: Formatting changes.
3186         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3187         prevents type checking.
3188         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3189         cast the value to (void *): assigning a `foo *' to a `void *'
3190         variable is valid.
3191         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

3227
3228 2000-11-07  Akim Demaille  <akim@epita.fr>
3229
3230         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3231         Merge in a single CPP if/else.

3255
3256         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3272         * src/main.c (main): Don't use `atexit' to register `done', since
3273         it no longer has to remove tmp files, just call `output_files'
3274         when there are no errors.

3379         When a literal string is used to define two different tokens,
3380         `bison -v' segfaults.
3381         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3382
3383         * tests/regression.m4: New file.
3384         Include the core of the sample provided by Piotr Gackiewicz.

3386         properly.
3387
3388 2000-10-04  Akim Demaille  <akim@epita.fr>
3389
3390         * src/reader.c (parse_expect_decl): Keep `count' within the size
3391         of `buffer'.
3392         From Neil Booth.
3393
3394 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3395
3396         * bison.s1 (yyparse): Assign the default value
3397         unconditionally, to avoid a GCC warning and make the parser a
3398         tad smaller.
3399
3400 2000-10-02  Akim Demaille  <akim@epita.fr>
3401
3402         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3403         options.
3404
3405 2000-10-02  Akim Demaille  <akim@epita.fr>
3406
3407         * src/derives.c, src/print.c, src/reduce.c: To ease the
3408         translation, move some `\n' out of the translated strings.
3409
3410 2000-10-02  Akim Demaille  <akim@epita.fr>
3411
3412         The location tracking mechanism is precious for parse error
3413         messages.  Nevertheless, it is enabled only when `@n' is used in
3414         the grammar, which is a different issue (you can use it in error
3415         message, but not in the grammar per se).  Therefore, there should
3416         be another means to enable it.
3417
3418         * src/getargs.c (getargs): Support `--locations'.
3419         (usage): Report it.
3420         * src/getargs.h (locationsflag): Export it.
3421         * src/lex.c (percent_table): Support `%locations'.
3422         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3423         with `locationsflag'.
3424         * doc/bison.texinfo: Document `--locations' and `%locations'.
3425         Sort the options.
3426         * tests/calc.m4: Test it.
3427
3428         For regularity of the names, replace each
3429         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3430         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3431         In addition replace each `flag' with `_flag'.
3432
3433 2000-10-02  Akim Demaille  <akim@epita.fr>
3434
3435         Also test parse error messages, including with YYERROR_VERBOSE.
3436
3437         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3438         associative).
3439         Use it to check the computations.
3440         Use it to check `nonassoc' is honored.
3441         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3442         `--yyerror-verbose'.
3443         (_AT_CHECK_CALC): Adjust to this option.
3444         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3445
3446 2000-10-02  Akim Demaille  <akim@epita.fr>
3447
3448         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3449         the latter demonstrates a flaw in the handling of non debugging
3450         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3451         was used in order to simplify:
3452
3453         #if YYDEBUG
3454         if (yydebug)
3455         {
3456         ...
3457         }
3458         #endif
3459
3460         into
3461
3462         if (yydebug)
3463         {
3464         ...
3465         }
3466
3467         unfortunately this leads to a CPP conflict when
3468         `--name-prefix=foo' is used since it produces `#define yydebug
3469         foodebug'.
3470
3471         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3472         (YYDPRINTF): New macro.
3473         Spread its use.
3474         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3475         the bison options.
3476         Also test `--verbose', `--defines' and `--name-prefix'.
3477
3478 2000-10-02  Akim Demaille  <akim@epita.fr>
3479
3480         Improve the readability of the produced parsers.
3481
3482         * src/bison.s1: Formatting changes.
3483         Improve the comment related to the `$' mark.
3484         (yydefault): Don't fall through to `yyresume': `goto' there.
3485         * src/output.c (output_parser): When the `$' is met, skip the end
3486         of its line.
3487         New variable, `number_of_dollar_signs', to check there's exactly
3488         one `$' in the parser skeleton.
3489
3490 2000-10-02  Akim Demaille  <akim@epita.fr>
3491
3492         * lib/xstrdup.c: New file, from the fileutils.
3493         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3494         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3495         instead of strlen + xmalloc + strcpy.
3496         * src/symtab.c (copys): Remove, use xstrdup instead.
3497
3498 2000-10-02  Akim Demaille  <akim@epita.fr>
3499
3500         * src/gram.h (associativity): New enum type which replaces the
3501         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3502         `right_assoc', `left_assoc' and `non_assoc'.
3503         Adjust all dependencies.
3504         * src/reader.c: Formatting changes.
3505         (LTYPESTR): Don't define it, use it as a literal in
3506         `reader_output_yylsp'.
3507         * src/symtab.h (symbol_class): New enum type which replaces the
3508         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3509         `sunknown', `stoken and `snterm'.
3510
3511 2000-10-02  Akim Demaille  <akim@epita.fr>
3512
3513         * src/getargs.c (fixed_outfiles): Rename as...
3514         (yaccflag): for consistency and accuracy.
3515         Adjust dependencies.
3516
3517 2000-10-02  Akim Demaille  <akim@epita.fr>
3518
3519         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3520         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3521         difficult and introduced a lot of core dump.  It turns out that
3522         Bison used an implementation of `xmalloc' based on `calloc', and
3523         at various places it does depend upon the initialization to 0.  I
3524         have not tried to isolate the pertinent places, and all the former
3525         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3526         someone should address this issue.
3527
3528         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3529         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

3540
3541 2000-10-02  Akim Demaille  <akim@epita.fr>
3542
3543         * src/state.h (nstates, final_state, first_state, first_shift)
3544         (first_reduction): Move their exportation from here...
3545         * src/LR0.h: to here.
3546         Adjust dependencies.
3547         * src/getargs.c (statisticsflag): New variable.

3601         * src/reader.h: New file.
3602         Propagate its use instead of tedious list of `extern' and
3603         prototypes.
3604         * src/reader.c: Formatting changes, topological sort,
3605         s/register//.
3606
3607 2000-10-02  Akim Demaille  <akim@epita.fr>
3608
3609         * src/lex.h: Prototype `lex.c' exported functions.
3610         * src/reader.c: Adjust.
3611         * src/lex.c: Formatting changes.
3612         (safegetc): Rename as...
3613         (xgetc): this.
3614
3615 2000-10-02  Akim Demaille  <akim@epita.fr>
3616
3617         * src/lalr.h: New file.

3620
3621 2000-10-02  Akim Demaille  <akim@epita.fr>
3622
3623         * src/output.c (token_actions): Introduce a temporary array,
3624         YYDEFACT, that makes it possible for this function to use
3625         output_short_table.
3626
3627 2000-10-02  Akim Demaille  <akim@epita.fr>
3628
3629         `user_toknums' is output as a `short[]' in `output.c', while it is
3630         defined as a `int[]' in `reader.c'.  For consistency with the
3631         other output tables, `user_toknums' is now defined as a table of
3632         shorts.
3633
3634         * src/reader.c (user_toknums): Be a short table instead of an int
3635         table.
3636         Adjust dependencies.
3637
3638         Factor the short table outputs.
3639
3640         * src/output.c (output_short_table): New function.
3641         * src/output.c (output_gram, output_stos, output_rule_data)

3643
3644 2000-10-02  Akim Demaille  <akim@epita.fr>
3645
3646         * src/output.c (output): Topological sort of the functions, in
3647         order to get rid of the `static' prototypes.
3648         No longer use `register'.
3649         * src/output.h: New file.
3650         Propagate its inclusion in files explicitly prototyping functions
3651         from output.c.
3652
3653 2000-09-21  Akim Demaille  <akim@epita.fr>

3660         * src/closure.c: Formatting changes, topological sort over the
3661         functions, use of closure.h.
3662         (initialize_closure, finalize_closure):  Rename as...
3663         (new_closure, free_closure): these.  Adjust dependencies.
3664         * src/LR0.c: Formatting changes, topological sort, use of
3665         cloture.h.

3670 2000-09-20  Akim Demaille  <akim@epita.fr>
3671
3672         * src/acconfig.h: Don't protect config.h against multiple
3673         inclusion.
3674         Don't define PARAMS.
3675         * src/system.h: Define PARAMS.
3676         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3677         purpose of config.h.  system.h must not try to fix wrong
3678         definitions in config.h.
3679
3680 2000-09-20  Akim Demaille  <akim@epita.fr>

3692         Use these macros to test bison with options `', `--raw',
3693         `--debug', `--yacc', `--yacc --debug'.
3694
3695 2000-09-19  Akim Demaille  <akim@epita.fr>
3696
3697         * src/output.c: Formatting changes.
3698         * src/machine.h: Remove, leaving its contents in...

3703         Let all `extern' declarations about getargs.c be replaced with

3718

3756         (VERSION_STRING): Remove.
3757
3758 2000-04-14  Akim Demaille  <akim@epita.fr>
3759
3760         * src/reader.c (copy_comment2): New function, same as former

3815         * configure.in: Adjust.
3816         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

3838
3839         * src/Makefile.am (bison.simple): Fix the awk program: quote only
3840         the file name, not the whole `#line LINE FILE'.
3841
3842 2000-03-17  Akim Demaille  <akim@epita.fr>
3843
3844         On syntax errors, report the token on which we choked.
3845
3846         * src/bison.s1 (yyparse): In the label yyerrlab, when

3864
3865         * src/reader.c (copy_definition): Use copy_string and
3866         copy_comment.  Removed now unused `match', `ended',
3867         `cplus_comment'.
3868         (copy_comment, copy_string): Moved, to be visible from
3869         copy_definition.
3870
3871 2000-03-17  Akim Demaille  <akim@epita.fr>
3872
3873         * src/reader.c (copy_string): Declare `static inline'.  No
3874         problems with inline, since it is checked by configure.

3895
3896         Change the handling of @s so that they behave exactly like $s.
3897         There is now a pseudo variable @$ (readble and writable), location
3898         of the lhs of the rule (by default ranging from the location of
3899         the first symbol of the rhs, to the location of the last symbol,
3900         or, if the rhs is empty, YYLLOC).
3901
3902         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3903         yyval.
3904         (yyparse): When providing a default semantic action, provide a
3905         default location action.
3906         (after the $): No longer change `*YYLSP', just stack YYLOC the
3907         same way you stack YYVAL.
3908         * src/reader.c (read_declarations): Use warns.
3909         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3910         (copy_action, case '@'): Likewise.
3911         Use a standard error message, to save useless work from
3912         translators.
3913
3914 2000-03-17  Akim Demaille  <akim@epita.fr>
3915
3916         * src/bison.s1: Formatting and cosmetics changes.

3918         Update the Copyright notice.
3919
3920 2000-03-17  Akim Demaille  <akim@epita.fr>
3921
3922         * src/bison.s1 (#line): All set to `#line' only, since the
3923         Makefile now handles them.
3924
3925 2000-03-16  Akim Demaille  <akim@epita.fr>
3926

3931
3932 2000-03-16  Akim Demaille  <akim@epita.fr>
3933
3934         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
3935         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3936         One `#if YYDEBUG' remains, since it uses variables which are
3937         defined only if `YYDEBUG != 0'.
3938
3939 2000-03-16  Akim Demaille  <akim@epita.fr>
3940
3941         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
3942         and related variables so that the similarities are highlighted.

3949
3950         * src/bison.s1: Properly indent the `alloca' CPP section.
3951
3952 2000-03-16  Akim Demaille  <akim@epita.fr>
3953
3954         Do not hard code values of directories in `configure.in'.
3955         Update the `configure' tool chain.
3956
3957         * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by
3958         src/makefile.am.
3959         (VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED.
3960         (AC_OUTPUT): Add m4/Makefile.
3961         Bump to bison 1.28a, 1.29 has never been released.
