ChangeLog

   1 2001-12-29  Akim Demaille  <akim@epita.fr>
   2
   3         %name-prefix is broken.
   4
   5         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
   6         Adjust all dependencies.
   7         * tests/headers.at (export YYLTYPE): Strengthen this test: use
   8         %name-prefix.
   9
  10         Renaming yylval but not yylloc is not consistent.  Now we do.
  11
  12         * src/bison.simple: Prefix yylloc if used.
  13         * doc/bison.texinfo (Decl Summary): Document that.
  14
  15 2001-12-29  Akim Demaille  <akim@epita.fr>
  16
  17         * doc/bison.texinfo: Promote `%long-directive' over
  18         `%long_directive'.
  19         Remove all references to fixed-output-files, yacc is enough.
  20
  21 2001-12-29  Akim Demaille  <akim@epita.fr>
  22
  23         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
  24         user prologue.  These are defaults.
  25         * tests/actions.at (Mid-rule actions): Make sure the user can
  26         define YYDEBUG and YYERROR_VERBOSE.
  27
  28 2001-12-29  Akim Demaille  <akim@epita.fr>
  29
  30         * src/output.c (header_output): Don't forget to export YYLTYPE and
  31         yylloc.
  32         * tests/headers.at (export YYLTYPE): New, make sure it does.
  33         * tests/regression.at (%union and --defines, Invalid CPP headers):
  34         Move to...
  35         * tests/headers.at: here.
  36
  37 2001-12-29  Akim Demaille  <akim@epita.fr>
  38
  39         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
  40
  41 2001-12-29  Akim Demaille  <akim@epita.fr>
  42
  43         * tests/actions.at (Mid-rule actions): Output on a single line
  44         instead of several.
  45
  46 2001-12-29  Akim Demaille  <akim@epita.fr>
  47
  48         * doc/bison.texinfo: Formatting changes.
  49
  50 2001-12-29  Akim Demaille  <akim@epita.fr>
  51
  52         Don't store the token defs in a muscle, just be ready to output it
  53         on command.  Now possible via `symbols'.  Fixes a memory leak.
  54
  55         * src/output.c (token_definitions_output): New.
  56         (output_parser, header_output): Use it.
  57         * src/reader.c (symbols_save): Remove.
  58
  59 2001-12-29  Akim Demaille  <akim@epita.fr>
  60
  61         * src/bison.simple: Do not provide a default for YYSTYPE and
  62         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
  63         default.
  64
  65 2001-12-29  Akim Demaille  <akim@epita.fr>
  66
  67         Mid-rule actions are simply... ignored!
  68
  69         * src/reader.c (readgram): Be sure to attach mid-rule actions to
  70         the empty-rule associated to the dummy symbol, not to the host
  71         rule.
  72         * tests/actions.at (Mid-rule actions): New.
  73
  74 2001-12-29  Akim Demaille  <akim@epita.fr>
  75
  76         Memory leak.
  77
  78         * src/reader.c (reader): Free grammar.
  79
  80 2001-12-29  Akim Demaille  <akim@epita.fr>
  81
  82         Memory leak.
  83
  84         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
  85         since it allocates it for each state, although only one is needed.
  86         (allocate_storage): Do it here.
  87
  88 2001-12-29  Akim Demaille  <akim@epita.fr>
  89
  90         * src/options.h, src/options.c (create_long_option_table): Rename
  91         as...
  92         (long_option_table_new): this, with a clearer prototype.
  93         (percent_table): Remove, unused,
  94         * src/getargs.c (getargs): Adjust.
  95
  96 2001-12-29  Akim Demaille  <akim@epita.fr>
  97
  98         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
  99         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 100         as states.
 101
 102 2001-12-29  Akim Demaille  <akim@epita.fr>
 103
 104         * src/lalr.c (build_relations): Rename `states' as `states1'.
 105         Sorry, I don't understand exactly what it is, no better name...
 106
 107 2001-12-29  Akim Demaille  <akim@epita.fr>
 108
 109         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 110         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 111         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 112         as rules.
 113
 114 2001-12-29  Akim Demaille  <akim@epita.fr>
 115
 116         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 117         ago.
 118
 119 2001-12-29  Akim Demaille  <akim@epita.fr>
 120
 121         * src/reader.c, src/reader.h (user_toknums): Remove.
 122         Adjust all users to use symbols[i]->user_token_number.
 123
 124 2001-12-29  Akim Demaille  <akim@epita.fr>
 125
 126         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 127         Adjust all users to use symbols[i]->prec or ->assoc.
 128
 129 2001-12-29  Akim Demaille  <akim@epita.fr>
 130
 131         * src/reader.c, src/reader.h (tags): Remove.
 132         Adjust all users to use symbols[i]->tag.
 133
 134 2001-12-29  Akim Demaille  <akim@epita.fr>
 135
 136         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 137         and rule_table.
 138         * src/reader.c (packsymbols): Fill this table.
 139         Drop sprec.
 140         * src/conflicts.c (resolve_sr_conflict): Adjust.
 141         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 142         single table.
 143         Use symbols[i]->tag instead of tags[i].
 144
 145 2001-12-29  Akim Demaille  <akim@epita.fr>
 146
 147         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 148         In addition, put a comment in there, to replace...
 149         * tests/regression.at (%union and C comments): Remove.
 150
 151 2001-12-29  Akim Demaille  <akim@epita.fr>
 152
 153         * tests/regression.at (Web2c Actions): Blindly move the actual
 154         output as expected output.  The contents *seem* right to me, but I
 155         can't pretend reading perfectly parser tables...  Nonetheless, all
 156         the other tests pass correctly, the table look OK, even though the
 157         presence of `$axiom' is to be noted: AFAICS it is useless (but
 158         harmless).
 159
 160 2001-12-29  Akim Demaille  <akim@epita.fr>
 161
 162         * src/reader.c (readgram): Don't add the rule 0 if there were no
 163         rules read.  In other words, add it _after_ having performed
 164         grammar sanity checks.
 165         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 166
 167 2001-12-29  Akim Demaille  <akim@epita.fr>
 168
 169         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 170         visible, and some states have now a different number.
 171
 172 2001-12-29  Akim Demaille  <akim@epita.fr>
 173
 174         * src/reader.c (readgram): Bind the initial rule's lineno to that
 175         of the first rule.
 176         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 177         (Solved SR Conflicts): Adjust rule 0's line number.
 178
 179 2001-12-29  Akim Demaille  <akim@epita.fr>
 180
 181         Fix the `GAWK Grammar' failure.
 182
 183         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 184         the reductions of the first state which was mistakenly confused
 185         with the final state because precisely final_state was initialized
 186         to 0.
 187         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 188         now noticed by Bison.
 189         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 190         have a reduction on $default.
 191
 192 2001-12-29  Akim Demaille  <akim@epita.fr>
 193
 194         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 195         rule line numbers.
 196         * src/closure.c (print_closure): Likewise.
 197         * src/derives.c (print_derives): Likewise.
 198         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 199         now.
 200
 201 2001-12-29  Akim Demaille  <akim@epita.fr>
 202
 203         * src/lalr.c (lookaheads_print): New.
 204         (lalr): Call it when --trace-flag.
 205         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 206         are dumped.
 207
 208 2001-12-29  Akim Demaille  <akim@epita.fr>
 209
 210         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 211         when walking through ritem, even via rule->rhs.
 212         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 213         (useful_production, useless_nonterminals): Likewise.
 214         (reduce_grammar_tables): Likewise, plus update nritems.
 215         * src/nullable.c (set_nullable): Likewise.
 216         * src/lalr.c (build_relations): Likewise.
 217         * tests/sets.at (Nullable): Adjust.
 218         Fortunately, now, the $axiom is no longer nullable.
 219
 220 2001-12-29  Akim Demaille  <akim@epita.fr>
 221
 222         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 223         the 0-sentinel.
 224         * src/gram.c (ritem_longest_rhs): Likewise.
 225         * src/reduce.c (nonterminals_reduce): Likewise.
 226         * src/print_graph.c (print_graph): Likewise.
 227         * src/output.c (output_rule_data): Likewise.
 228         * src/nullable.c (set_nullable):  Likewise.
 229
 230 2001-12-29  Akim Demaille  <akim@epita.fr>
 231
 232         * src/output.c: Comment changes.
 233
 234 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 235
 236         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 237         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 238         Sparc, as they were causing more porting problems than the
 239         (minor) performance improvement was worth.
 240
 241         Also, catch up with 1.31's YYSTD.
 242
 243 2001-12-27  Akim Demaille  <akim@epita.fr>
 244
 245         * src/output.c (output_gram): Rely on nritems, not the
 246         0-sentinel.  See below.
 247         Use -1 as separator, not 0.
 248         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 249         Rely on -1 as separator in yyrhs, instead of 0.
 250         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 251         twice `Now at end of input', therefore there are two lines less to
 252         expect.
 253
 254 2001-12-27  Akim Demaille  <akim@epita.fr>
 255
 256         * tests/regression.at (Unresolved SR Conflicts):
 257         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 258         below.
 259
 260 2001-12-27  Akim Demaille  <akim@epita.fr>
 261
 262         * src/LR0.c (new_state): Recognize the final state by the fact it
 263         is reached by eoftoken.
 264         (insert_start_shifting_state, insert_eof_shifting_state)
 265         (insert_accepting_state, augment_automaton): Remove, since now
 266         these states are automatically computed from the initial state.
 267         (generate_states): Adjust.
 268         * src/print.c: When reporting a rule number to the user, substract
 269         1, so that the axiom rule is rule 0, and the first user rule is 1.
 270         * src/reduce.c: Likewise.
 271         * src/print_graph.c (print_core): For the time being, just as for
 272         the report, depend upon --trace-flags to dump the full set of
 273         items.
 274         * src/reader.c (readgram): Once the grammar read, insert the rule
 275         0: `$axiom: START-SYMBOL $'.
 276         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 277         number of the states has changed (the final state is no longer
 278         necessarily the last), catch up.
 279
 280 2001-12-27  Akim Demaille  <akim@epita.fr>
 281
 282         Try to make the use of the eoftoken valid.  Given that its value
 283         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 284         is used instead of > 0 where appropriate, (ii), depend upon nritems
 285         instead of the 0-sentinel.
 286
 287         * src/gram.h, src/gram.c (nritems): New.
 288         Expected to be duplication of nitems, but for the time being...
 289         * src/reader.c (packgram): Assert nritems and nitems are equal.
 290         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 291         * src/closure.c (print_closure, print_fderives): Likewise.
 292         * src/gram.c (ritem_print): Likewise.
 293         * src/print.c (print_core, print_grammar): Likewise.
 294         * src/print_graph.c: Likewise.
 295
 296 2001-12-27  Akim Demaille  <akim@epita.fr>
 297
 298         * src/main.c (main): If there are complains after grammar
 299         reductions, then output the report anyway if requested, then die.
 300         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 301         * src/reader.c (eoftoken): New.
 302         (parse_token_decl): If the token being defined has value `0', it
 303         is the eoftoken.
 304         (packsymbols): No longer hack `tags' to insert `$' by hand.
 305         Be sure to preserve the value of the eoftoken.
 306         (reader): Make sure eoftoken is defined.
 307         Initialize nsyms to 0: now eoftoken is created just like the others.
 308         * src/print.c (print_grammar): Don't special case the eof token.
 309         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 310         lie anyway, albeit pleasant.
 311         * tests/calc.at: Exercise error messages with eoftoken.
 312         Change the grammar so that empty input is invalid.
 313         Adjust expectations.
 314         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 315
 316 2001-12-27  Akim Demaille  <akim@epita.fr>
 317
 318         * configure.in: Check the protos of strchr ans strspn.
 319         Replace strchr if needed.
 320         * src/system.h: Provide the protos of strchr, strspn and memchr if
 321         missing.
 322         * lib/strchr.c: New.
 323         * src/reader.c (symbols_save): Use strchr.
 324
 325 2001-12-27  Akim Demaille  <akim@epita.fr>
 326
 327         * src/print.c, src/print_graph.c (escape): New.
 328         Use it to quote the TAGS outputs.
 329         * src/print_graph.c (print_state): Now errors are in red, and
 330         reductions in green.
 331         Prefer high to wide: output the state number on a line of its own.
 332
 333 2001-12-27  Akim Demaille  <akim@epita.fr>
 334
 335         * src/state.h, src/state.c (reductions_new): New.
 336         * src/LR0.c (set_state_table): Let all the states have a
 337         `reductions', even if reduced to 0.
 338         (save_reductions): Adjust.
 339         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 340         * src/print.c (print_reductions, print_actions): Adjust.
 341         * src/output.c (action_row): Adjust.
 342
 343 2001-12-27  Akim Demaille  <akim@epita.fr>
 344
 345         * src/state.h, src/state.c (errs_new, errs_dup): New.
 346         * src/LR0.c (set_state_table): Let all the states have an errs,
 347         even if reduced to 0.
 348         * src/print.c (print_errs, print_reductions): Adjust.
 349         * src/output.c (output_actions, action_row): Adjust.
 350         * src/conflicts.c (resolve_sr_conflict): Adjust.
 351
 352 2001-12-27  Akim Demaille  <akim@epita.fr>
 353
 354         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 355
 356 2001-12-27  Akim Demaille  <akim@epita.fr>
 357
 358         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 359         * src/print.c: here.
 360         (lookaheadset, shiftset): New, used as additional storage by
 361         print_reductions.
 362         (print_results): Adjust.
 363         (print_shifts, print_gotos, print_errs): New, extracted from...
 364         (print_actions): here.
 365         * src/print_graph.c (print_actions): Remove dead code.
 366
 367 2001-12-27  Akim Demaille  <akim@epita.fr>
 368
 369         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 370         `$n' and `@n'.
 371
 372 2001-12-27  Akim Demaille  <akim@epita.fr>
 373
 374         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 375         (build_relations): Adjust.
 376
 377 2001-12-27  Akim Demaille  <akim@epita.fr>
 378
 379         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 380         duplication.
 381
 382 2001-12-27  Akim Demaille  <akim@epita.fr>
 383
 384         * src/reader.c (packgram): Catch nitems overflows.
 385
 386 2001-12-27  Akim Demaille  <akim@epita.fr>
 387
 388         * src/files.c, src/files.h (guard_obstack): Remove.
 389         * src/output.c (output): Adjust.
 390         * src/reader.c (parse_braces): New, factoring...
 391         (copy_action, copy_guard): these two which are renamed as...
 392         (parse_action, parse_guard): these.
 393         As a voluntary consequence, using braces around guards is now
 394         mandatory.
 395
 396 2001-12-27  Akim Demaille  <akim@epita.fr>
 397
 398         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 399         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 400         members.
 401         (symbol_list_new): Adjust.
 402         (copy_action): action_line is the first line, not the last.
 403         (copy_guard): Just as for actions, store the `action' only, not
 404         the switch/case/break flesh.
 405         Don't parse the user action that might follow the guard, let...
 406         (readgram): do it, i.e., now, there can be an action after a
 407         guard.
 408         In other words the guard is just explicitly optional.
 409         (packgram): Adjust.
 410         * src/output.c (guards_output): New.
 411         (output_parser): Call it when needed.
 412         (output): Also free the guard and attrs obstacks.
 413         * src/files.c, src/files.h (obstack_save): Remove.
 414         (output_files): Remove.
 415         As a result, if one needs the former `.act' file, using an
 416         appropriate skeleton which requires actions and guards is now
 417         required.
 418         * src/main.c (main): Adjust.
 419         * tests/semantic.at: New.
 420         * tests/regression.at: Use `input.y' as input file name.
 421         Avoid 8+3 problems by requiring input.c when the test needs the
 422         parser.
 423
 424 2001-12-27  Akim Demaille  <akim@epita.fr>
 425
 426         * src/reader.c (symbol_list_new): Be sure to initialize all the
 427         fields.
 428
 429 2001-12-27  Akim Demaille  <akim@epita.fr>
 430
 431         All the hacks using a final pseudo state are now useless.
 432
 433         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 434         * src/lalr.c (nLA): New.
 435         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 436         instead of lookaheadsp from the pseudo state (nstate + 1).
 437
 438 2001-12-27  Akim Demaille  <akim@epita.fr>
 439
 440         * src/output.c (action_row, token_actions): Use a state_t instead
 441         of a integer, and nlookaheads instead of the following state's
 442         lookaheadsp.
 443
 444 2001-12-27  Akim Demaille  <akim@epita.fr>
 445
 446         * src/conflicts.c (log_resolution, flush_shift)
 447         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 448         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 449         (conflicts_print, print_reductions): Use a state_t instead of an
 450         integer when referring to a state.
 451         As much as possible, depend upon nlookaheads, instead of the
 452         `lookaheadsp' member of the following state (since lookaheads of
 453         successive states are successive, the difference between state n + 1
 454         and n served as the number of lookaheads for state n).
 455         * src/lalr.c (add_lookback_edge): Likewise.
 456         * src/print.c (print_core, print_actions, print_state)
 457         (print_results): Likewise.
 458         * src/print_graph.c (print_core, print_actions, print_state)
 459         (print_graph): Likewise.
 460         * src/conflicts.h: Adjust.
 461
 462 2001-12-27  Akim Demaille  <akim@epita.fr>
 463
 464         * src/bison.hairy: Formatting/comment changes.
 465         ANSIfy.
 466         Remove `register' indications.
 467         Add plenty of `static'.
 468
 469 2001-12-27  Akim Demaille  <akim@epita.fr>
 470
 471         * src/output.c (prepare): Drop the muscle `ntbase' which
 472         duplicates ntokens.
 473         * src/bison.simple: Formatting/comment changes.
 474         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 475         is an undocumented synonym.
 476
 477 2001-12-22  Akim Demaille  <akim@epita.fr>
 478
 479         * src/output.c (output_table_data): Change the prototype to use
 480         `int' for array ranges: some invocations do pass an int, not a
 481         short.
 482         Reported by Wayne Green.
 483
 484 2001-12-22  Akim Demaille  <akim@epita.fr>
 485
 486         Some actions of web2c.y are improperly triggered.
 487         Reported by Mike Castle.
 488
 489         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 490         * tests/regression.at (Web2c): Rename as...
 491         (Web2c Report): this.
 492         (Web2c Actions): New.
 493
 494 2001-12-22  Akim Demaille  <akim@epita.fr>
 495
 496         Reductions in web2c.y are improperly reported.
 497         Reported by Mike Castle.
 498
 499         * src/conflicts.c (print_reductions): Fix.
 500         * tests/regression.at (Web2c): New.
 501
 502 2001-12-18  Akim Demaille  <akim@epita.fr>
 503
 504         Some host fail on `assert (!"foo")', which expands to
 505         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 506         Reported by Nelson Beebee.
 507
 508         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 509         `#define it_succeeded 0' and `assert (it_succeeded)'.
 510
 511 2001-12-17  Marc Autret  <autret_m@epita.fr>
 512
 513         * src/bison.simple: Don't hard code the skeleton line and filename.
 514         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 515         New line counter 'skeleton_line' (skeleton-line muscle).
 516
 517 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 518
 519         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 520         YYDEBUG must be defined to a nonzero value.
 521
 522         * src/bison.simple (yytname): Do not assume that the user defines
 523         YYDEBUG to a properly parenthesized expression.
 524
 525 2001-12-17  Akim Demaille  <akim@epita.fr>
 526
 527         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 528         nlookaheads is a new member.
 529         Adjust all users.
 530         * src/lalr.h (nlookaheads): Remove this orphan declaration.
 531         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 532         state.
 533
 534 2001-12-17  Akim Demaille  <akim@epita.fr>
 535
 536         * src/files.h, src/files.c (open_files, close_files): Remove.
 537         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 538         let...
 539         * src/reader.c (reader): Do it.
 540
 541 2001-12-17  Akim Demaille  <akim@epita.fr>
 542
 543         * src/conflicts.c (print_reductions): Formatting changes.
 544
 545 2001-12-17  Akim Demaille  <akim@epita.fr>
 546
 547         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 548         (flush_reduce): New.
 549         (resolve_sr_conflict): Adjust.
 550
 551 2001-12-17  Akim Demaille  <akim@epita.fr>
 552
 553         * src/output.c (output_obstack): Be static and rename as...
 554         (format_obstack): this, to avoid any confusion with files.c's
 555         output_obstack.
 556         * src/reader.h (muscle_obstack): Move to...
 557         * src/output.h: here, since it's defined in output.c.
 558
 559 2001-12-17  Akim Demaille  <akim@epita.fr>
 560
 561         * src/output.c (action_row, save_column, default_goto)
 562         (sort_actions, matching_state, pack_vector): Better variable
 563         locality.
 564
 565 2001-12-17  Akim Demaille  <akim@epita.fr>
 566
 567         * src/output.c: Various formatting changes.
 568
 569 2001-12-17  Akim Demaille  <akim@epita.fr>
 570
 571         * src/files.c (output_files): Free the output_obstack.
 572         * src/main.c (main): Call print and print_graph conditionally.
 573         * src/print.c (print): Work unconditionally.
 574         * src/print_graph.c (print_graph): Work unconditionally.
 575         * src/conflicts.c (log_resolution): Output only if verbose_flag.
 576
 577 2001-12-16  Marc Autret  <autret_m@epita.fr>
 578
 579         * src/output.c (actions_output): Fix. When we use %no-lines,
 580         there is one less line per action.
 581
 582 2001-12-16  Marc Autret  <autret_m@epita.fr>
 583
 584         * src/bison.simple: Remove a useless #line directive.
 585         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 586         * src/output.c (get_lines_number): New.
 587         (output_parser): Adjust, now takes care about the lines of a
 588         output muscles.
 589         Fix line numbering.
 590         (actions_output): Computes the number of lines taken by actions.
 591         (output_master_parser): Insert new skeleton which is the name of
 592         the output parser file name.
 593
 594 2001-12-15  Marc Autret  <autret_m@epita.fr>
 595
 596         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
 597
 598 2001-12-15  Marc Autret  <autret_m@epita.fr>
 599
 600         * src/output.c (output_gram): Keep track of the hairy one.
 601
 602 2001-12-15  Akim Demaille  <akim@epita.fr>
 603
 604         Make `make distcheck' work.
 605
 606         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 607         system.h which uses libgettext.h.
 608
 609 2001-12-15  Akim Demaille  <akim@epita.fr>
 610
 611         * src/nullable.c (set_nullable): Useless rules must be skipped,
 612         otherwise, since we range over their symbols, we might look at a
 613         nonterminal which no longer ``exists'', i.e., it is not counted in
 614         `nvars', hence we overflow our arrays.
 615
 616 2001-12-15  Akim Demaille  <akim@epita.fr>
 617
 618         The header can also be produced directly, without any obstack!
 619         Yahoo!
 620
 621         * src/files.c, src/files.h (defines_obstack): Remove.
 622         (compute_header_macro): Global.
 623         (defines_obstack_save): Remove.
 624         * src/reader.c (parse_union_decl): No longer output to
 625         defines_obstack: its content can be found in the `stype' muscle
 626         anyway.
 627         (output_token_translations): Merge into...
 628         (symbols_output): this.
 629         Rename as...
 630         (symbols_save): this.
 631         (reader): Adjust.
 632         * src/output.c (header_output): New.
 633         (output): Call it.
 634
 635 2001-12-15  Akim Demaille  <akim@epita.fr>
 636
 637         * src/reader.c (parse_union_decl): Instead of handling two obstack
 638         simultaneously, use one to define the `stype' muscle, and use the
 639         value of the latter to fill defines_obstack.
 640         (copy_comment): Remove.
 641         (copy_comment2): Work for a single obstack.
 642         Rename as...
 643         (copy_comment): this.
 644
 645 2001-12-15  Akim Demaille  <akim@epita.fr>
 646
 647         * src/lex.c, src/lex.h (xgetc): No longer static.
 648         * src/reader.c (parse_union_decl): Revamp.
 649
 650 2001-12-15  Akim Demaille  <akim@epita.fr>
 651
 652         Still making progress in separating Bison into (i) input, (ii)
 653         process, (iii) output: now we can directly output the parser file
 654         without using table_obstack at all.
 655
 656         * src/files.c, src/files.h (table_obstack): Bye bye.
 657         (parser_file_name): New.
 658         * src/files.c (compute_output_file_names): Compute it.
 659         * src/output.c (actions_output, output_parser)
 660         (output_master_parser): To a file instead of an obstack.
 661
 662 2001-12-15  Akim Demaille  <akim@epita.fr>
 663
 664         Attach actions to rules, instead of pre-outputting them to
 665         actions_obstack.
 666
 667         * src/gram.h (rule_t): action and action_line are new members.
 668         * src/reader.c (symbol_list): Likewise.
 669         (copy_action): Save the actions within the rule.
 670         (packgram): Save them in rule_table.
 671         * src/output.c (actions_output): New.
 672         (output_parser): Use it on `%%actions'.
 673         (output_rule_data): Don't free rule_table.
 674         (output): Do it.
 675         (prepare): Don't save the `action' muscle.
 676         * src/bison.simple: s/%%action/%%actions/.
 677
 678 2001-12-15  Akim Demaille  <akim@epita.fr>
 679
 680         * src/reader.c (copy_action): When --yacc, don't append a `;'
 681         to the user action: let it fail if lacking.
 682         Suggested by Arnold Robbins and Tom Tromey.
 683
 684 2001-12-14  Akim Demaille  <akim@epita.fr>
 685
 686         * src/lex.c (literalchar): Simply return the char you decoded, non
 687         longer mess around with obstacks and int pointers.
 688         Adjust all callers.
 689
 690 2001-12-14  Akim Demaille  <akim@epita.fr>
 691
 692         * src/lex.c (literalchar): Don't escape the special characters,
 693         just decode them, and keep them as char (before, eol was output as
 694         the 2 char string `\n' etc.).
 695         * src/output.c (output_rule_data): Use quotearg to output the
 696         token strings.
 697
 698 2001-12-13  Paul Eggert  <eggert@twinsun.com>
 699
 700         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
 701         Do not infringe on the global user namespace when using C++.
 702         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
 703         All uses of `fprintf' and `stderr' changed.
 704
 705         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
 706
 707 2001-12-13  Akim Demaille  <akim@epita.fr>
 708
 709         The computation of nullable is broken: it doesn't handle empty
 710         RHS's properly.
 711
 712         * tests/torture.at (GNU AWK Grammar): New.
 713         * tests/sets.at (Nullable): New.
 714         * src/nullable.c (set_nullable): Instead of blindly looping over
 715         `ritems', loop over the rules, and then over their rhs's.
 716
 717         Work around Autotest bugs.
 718
 719         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
 720         frame, because Autotest understand lines starting with a `+' as
 721         traces from the shell.  Then, they are not processed properly.
 722         Admittedly an Autotest bug, but we don't have time to wait for
 723         Autotest to catch up.
 724         * tests/regression.at (Broken Closure): Adjust to the new table
 725         frames.
 726         Move to...
 727         * tests/sets.at: here.
 728
 729 2001-12-13  Akim Demaille  <akim@epita.fr>
 730
 731         * src/closure.c (closure): Use nrules instead of playing tricks

 734 2001-12-13  Akim Demaille  <akim@epita.fr>
 735
 736         * src/print.c (print_actions): Output the handling of `$' as the
 737         traces do: shifting the token EOF.  Before EOF was treated as a
 738         nonterminal.
 739         * tests/regression.at: Adjust some tests.
 740         * src/print_graph.c (print_core): Complete the set of items via
 741         closure.  The next-to-final and final states are still unsatisfying,
 742         but that's to be addressed elsewhere.
 743         No longer output the rule numbers, but do output the state number.
 744         A single loop for the shifts + gotos is enough, but picked a
 745         distinct color for each.
 746         (print_graph): Initialize and finalize closure.
 747
 748 2001-12-13  Akim Demaille  <akim@epita.fr>
 749
 750         * src/reader.c (readgram): Remove dead code, an strip useless
 751         braces.
 752         (get_type): Remove, unused.
 753
 754 2001-12-12  Akim Demaille  <akim@epita.fr>
 755
 756         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 757         on that of lib/error.c.
 758
 759 2001-12-12  Akim Demaille  <akim@epita.fr>
 760
 761         Some hosts don't like `/' in includes.
 762
 763         * src/system.h: Include libgettext.h without qualifying the path.
 764         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 765         $(top_srcdir).
 766
 767 2001-12-11  Marc Autret  <autret_m@epita.fr>
 768
 769         * src/output.c (output_parser): Remove useless muscle.
 770
 771 2001-12-11  Marc Autret  <autret_m@epita.fr>
 772
 773         * src/bison.simple: Remove #line just before %%epilogue. It
 774         is now handled in ...
 775         * src/reader.c (read_additionnal_code): Add the output of a
 776         #line for the epilogue.
 777
 778 2001-12-10  Marc Autret  <autret_m@epita.fr>
 779
 780         * src/reader.c (copy_definition): Re-use CPP-outed code which
 781         replace precedent remove.
 782         * src/bison.simple: Remove #line before %%prologue because
 783         %%input-line is wrong at this time.
 784
 785 2001-12-10  Marc Autret  <autret_m@epita.fr>
 786
 787         * src/reader.c (symbols_output): Clean up.
 788         * src/output.c (output_gram, output): Clean up.
 789
 790 2001-12-10  Akim Demaille  <akim@epita.fr>
 791
 792         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 793         * src/LR0.c (set_state_table): here.
 794         * src/lalr.c (lalr): Call it.
 795
 796 2001-12-10  Akim Demaille  <akim@epita.fr>
 797
 798         * src/state.h (shifts): Remove the `number' member: shifts are
 799         attached to state, hence no longer need to be labelled with a
 800         state number.
 801
 802 2001-12-10  Akim Demaille  <akim@epita.fr>
 803
 804         Now that states have a complete set of members, the linked list of
 805         shifts is useless: just fill directly the state's shifts member.
 806
 807         * src/state.h (shifts): Remove the `next' member.
 808         * src/LR0.c (first_state, last_state): Remove.
 809         Adjust the callers.
 810         (augment_automaton): Don't look for the shifts that must be added
 811         a shift on EOF: it is those of the state we looked for!  But now,
 812         since shifts are attached, it is no longer needed to looking
 813         merely by its id: its number.
 814
 815 2001-12-10  Akim Demaille  <akim@epita.fr>
 816
 817         * src/LR0.c (augment_automaton): Better variable locality.
 818         Remove an impossible branch: if there is a state corresponding to
 819         the start symbol being shifted, then there is shift for the start
 820         symbol from the initial state.
 821
 822 2001-12-10  Akim Demaille  <akim@epita.fr>
 823
 824         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 825         only when appropriate: when insert_start_shifting_state' is not
 826         invoked.
 827         * tests/regression.at (Rule Line Numbers): Adjust.
 828
 829 2001-12-10  Akim Demaille  <akim@epita.fr>
 830
 831         * src/LR0.c (augment_automaton): Now that all states have shifts,
 832         merge the two cases addition shifts to the initial state.
 833
 834 2001-12-10  Akim Demaille  <akim@epita.fr>
 835
 836         * src/lalr.c (set_state_table): Move to...
 837         * src/LR0.c: here.
 838         * src/lalr.c (lalr): Don't call it...
 839         * src/LR0.c (generate_states): do it.
 840         * src/LR0.h (first_state): Remove, only the table is used.
 841
 842 2001-12-10  Akim Demaille  <akim@epita.fr>
 843
 844         * src/LR0.h (first_shift, first_reduction): Remove.
 845         * src/lalr.c: Don't use first_shift: find shifts through the
 846         states.
 847
 848 2001-12-10  Akim Demaille  <akim@epita.fr>
 849
 850         * src/LR0.c: Attach shifts to states as soon as they are
 851         computed.
 852         * src/lalr.c (set_state_table): Instead of assigning shifts to
 853         state, just assert that the mapping was properly done.
 854
 855 2001-12-10  Akim Demaille  <akim@epita.fr>
 856
 857         * src/LR0.c (insert_start_shift): Rename as...
 858         (insert_start_shifting_state): this.
 859         (insert_eof_shifting_state, insert_accepting_state): New.
 860         (augment_automaton): Adjust.
 861         Better locality of the variables.
 862         When looking if the start_symbol is shifted from the initial
 863         state, using `while (... symbol != start_symbol ...)' sounds
 864         better than `while (... symbol < start_symbol ...)': If fail
 865         to see how the order between symbols could be relevant!
 866
 867 2001-12-10  Akim Demaille  <akim@epita.fr>
 868
 869         * src/getargs.h: Don't declare `spec_name_prefix' and
 870         `spec_file_prefix', declared by src/files.h.
 871         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 872         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 873         * src/output.c (prepare): Adjust.
 874         * src/reader.c (symbols_output): Likewise.
 875         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 876
 877 2001-12-10  Akim Demaille  <akim@epita.fr>
 878
 879         * src/muscle_tab.c (muscle_init): NULL is a better default than
 880         `"0"'.
 881
 882 2001-12-10  Akim Demaille  <akim@epita.fr>
 883
 884         * src/reader.c (reader): Calling symbols_output once is enough.
 885
 886 2001-12-10  Akim Demaille  <akim@epita.fr>
 887
 888         Now that states have a complete set of members, the linked list of
 889         reductions is useless: just fill directly the state's reductions
 890         member.
 891
 892         * src/state.h (struct reductions): Remove member `number' and
 893         `next'.
 894         * src/LR0.c (first_reduction, last_reduction): Remove.
 895         (save_reductions): Don't link the new reductions, store them in
 896         this_state.
 897         * src/lalr.c (set_state_table): No need to attach reductions to
 898         states, it's already done.
 899         * src/output.c (output_actions): No longer free the shifts, then
 900         the reductions, then the states: free all the states and their
 901         members.
 902
 903 2001-12-10  Akim Demaille  <akim@epita.fr>
 904
 905         * src/options.c (OPTN, DRTV, BOTH): New.
 906         (option_table): Use them.
 907
 908         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 909         the job of system.h.
 910         * src/options.c: Don't include stdio.h and xalloc.h for the same
 911         reasons.
 912
 913 2001-12-10  Akim Demaille  <akim@epita.fr>
 914
 915         * src/output.c (output, prepare): Make sure the values of the
 916         muscles `action' and `prologue' are 0-terminated.
 917
 918 2001-12-10  Akim Demaille  <akim@epita.fr>
 919
 920         Clean up GCC warnings.
 921
 922         * src/reader.c (copy_action): `buf' is not used.
 923         (parse_skel_decl): Be static.
 924         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 925         * src/options.h (create_long_option_table): Have a real prototype.
 926         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 927         (hash_delete_at): Return const void *.
 928         Adjust casts to preserve the const.
 929
 930 2001-12-10  Akim Demaille  <akim@epita.fr>
 931
 932         * configure.in: Require 2.52g.
 933         M4 is not needed, but AUTOM4TE is.
 934         * m4/m4.m4: Remove.
 935         * tests/Makefile.am: Adjust.
 936
 937 2001-12-10  Akim Demaille  <akim@epita.fr>
 938
 939         One structure for states is enough, even though theoretically
 940         there are LR(0) states and LALR(1) states.
 941
 942         * src/lalr.h (state_t): Remove.
 943         (state_table): Be state_t **, not state_t *.
 944         * src/state.h (core, CORE_ALLOC): Rename as...
 945         (state_t, STATE_ALLOC): this.
 946         Add the LALR(1) members: shifts, reductions, errs.
 947         * src/LR0.c (state_table): Rename as...
 948         (state_hash): this, to avoid name clashes with the global
 949         `state_table'.
 950         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 951         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 952
 953 2001-12-10  Akim Demaille  <akim@epita.fr>
 954
 955         Bison dumps core on bash.y.
 956         Reported by Pascal Bart.
 957
 958         * src/warshall.c (bitmatrix_print): New.
 959         (TC): Use it.
 960         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 961         j must be the outer loop.
 962         * tests/regression.at (Broken Closure): New.
 963
 964 2001-12-05  Akim Demaille  <akim@epita.fr>
 965
 966         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 967         its argument.
 968         Reported by Peter Hámorský.
 969
 970 2001-12-05  Akim Demaille  <akim@epita.fr>
 971
 972         * src/conflicts.c (err_table): Remove.
 973         (resolve_sr_conflict): Adjust.
 974         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 975         Rename as...
 976         (state_t.reductions, state_t.shifts): this.
 977
 978 2001-12-05  Akim Demaille  <akim@epita.fr>
 979
 980         * src/reduce.c (reduce_grammar_tables): No longer disable the
 981         removal of useless rules via CPP but via `if (0)', so that the
 982         compiler still check the code is valid.
 983         For instance, it should have noticed `rline' no longer exists: use
 984         the `line' member of rule_t.
 985         * src/gram.c (dummy, rline): Remove, unused.
 986
 987 2001-12-05  Akim Demaille  <akim@epita.fr>
 988
 989         * src/output.c (pack_vector): Use assert, not berror.
 990         * src/main.c (berror): Remove, unused.
 991
 992 2001-12-05  Akim Demaille  <akim@epita.fr>
 993
 994         New experimental feature: if --verbose --trace output all the
 995         items of a state, not only its kernel.
 996
 997         * src/print.c (print_core): If `trace_flag', then invoke closure
 998         before outputting the items of the state (print_core is no longer
 999         a correct name them).
1000         (print_results): Invoke new_closure/free_closure if needed.
1001
1002 2001-12-05  Akim Demaille  <akim@epita.fr>
1003
1004         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1005         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1006         (nitemset): for consistency with the rest of the project.
1007
1008 2001-12-05  Akim Demaille  <akim@epita.fr>
1009
1010         * src/closure.c (print_closure): Improve.
1011         (closure): Use it for printing input and output.
1012
1013 2001-12-05  Akim Demaille  <akim@epita.fr>
1014
1015         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1016         indexed by nonterminals.
1017
1018 2001-12-05  Akim Demaille  <akim@epita.fr>
1019
1020         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1021         what it was!).
1022         * src/warshall.h: Remove accidental duplication of the content.
1023
1024 2001-12-05  Akim Demaille  <akim@epita.fr>
1025
1026         * src/closure.c (set_fderives): De-obfuscate.

1035
1036 2001-12-05  Akim Demaille  <akim@epita.fr>
1037
1038         * src/output.c (action_row): De-obfuscate
1039         using the good o' techniques: arrays not pointers, variable
1040         locality, BITISSET, RESETBIT etc.
1041
1042 2001-12-05  Akim Demaille  <akim@epita.fr>
1043
1044         Pessimize the code to simplify it: from now on, all the states
1045         have a valid SHIFTS, which NSHIFTS is possibly 0.
1046
1047         * src/LR0.c (shifts_new): Be global and move to..
1048         * src/state.c, src/state.h: here.
1049         * src/conflicts, src/lalr.c, src/output.c, src/print.c,

1053
1054         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1055         * src/conflicts.c: Use it.
1056         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1057         incorrectly ``simplified''.
1058
1059 2001-12-05  Akim Demaille  <akim@epita.fr>
1060
1061         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

1063         locality, BITISSET, RESETBIT etc.
1064
1065 2001-12-05  Akim Demaille  <akim@epita.fr>
1066

1070 2001-12-05  Akim Demaille  <akim@epita.fr>
1071
1072         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1073         (print_reductions): De-obfuscate using the good o' techniques:
1074         arrays not pointers, variable locality, BITISSET.
1075
1076 2001-12-05  Akim Demaille  <akim@epita.fr>
1077
1078         * src/conflicts.c (print_reductions): Arrays, not pointers.

1104         * src/LR0.c (augment_automaton): Formatting changes.
1105         Better variable locality.
1106
1107 2001-12-05  Akim Demaille  <akim@epita.fr>
1108
1109         * src/lalr.c (matrix_print): New.
1110         (transpose): Use it.
1111         Use arrays instead of pointers.
1112
1113 2001-12-05  Akim Demaille  <akim@epita.fr>
1114
1115         * src/lalr.c (maxrhs): Move to...
1116         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1117         * src/lalr.c (build_relations): Adjust.
1118
1119 2001-12-05  Akim Demaille  <akim@epita.fr>
1120
1121         * src/lalr.c (transpose): Free the memory allocated to the
1122         argument, as it is replaced by the results by the unique caller.
1123         (build_relations): Merely invoke transpose: it handles the memory
1124         deallocation.
1125         Improve variable locality.
1126         Avoid variables used as mere abbreviations.
1127         (compute_lookaheads): Use arrays instead of pointers.
1128
1129 2001-12-05  Akim Demaille  <akim@epita.fr>
1130
1131         * src/lalr.c (initialize_F): Improve variable locality.
1132         Avoid variables used as mere abbreviations.
1133
1134 2001-12-05  Akim Demaille  <akim@epita.fr>
1135
1136         * src/derives.c (print_derives): Display the ruleno.
1137         * src/lalr.c (initialize_F, transpose): Better variable locality
1138         to improve readability.
1139         Avoid variables used as mere abbreviations.
1140
1141 2001-12-05  Akim Demaille  <akim@epita.fr>
1142
1143         * src/lalr.c (traverse): Use arrays instead of pointers.
1144
1145 2001-12-05  Akim Demaille  <akim@epita.fr>
1146
1147         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1148         the handling of squeue.
1149         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1150
1151 2001-12-05  Akim Demaille  <akim@epita.fr>
1152
1153         Because useless nonterminals are now kept alive (instead of being
1154         `destroyed'), we now sometimes examine them, and store information
1155         related to them.  Hence we need to know their number, and adjust
1156         memory allocations.
1157
1158         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1159         static.
1160         * src/LR0.c (allocate_itemsets): The memory allocated to
1161         `symbol_count' was used for two different purpose: once to count
1162         the number of occurrences of each symbol, and later reassigned to
1163         `shift_symbol', containing the symbol that can be shifted from a
1164         given state.
1165         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1166         only, and...
1167         (new_itemsets): Allocate `shift_symbol' here.
1168         (allocate_itemsets): symbol_count includes useless nonterminals.
1169         Make room for them.
1170         (free_storage): Use `free', not `XFREE', for pointers that cannot
1171         be null.
1172
1173 2001-12-05  Akim Demaille  <akim@epita.fr>
1174
1175         * src/nullable.c (set_nullable): Deobfuscate the handling of
1176         ritem.
1177         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1178
1179 2001-12-05  Akim Demaille  <akim@epita.fr>
1180
1181         * src/gram.c, src/gram.h (ritem_print): New.
1182         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1183         (This useless function was defined only to work around VMS linkers
1184         that can't handle compilation units with variables only).
1185         * src/reduce.c (dump_grammar): Use it to trace the construction of
1186         ritem.
1187
1188 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1189
1190         * src/bison.simple (union yyalloc): Change member names
1191         to be the same as the stack names.
1192         (yyparse): yyptr is now union yyalloc *, not char *.
1193         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1194         and may generate better code on some machines.
1195         (yystpcpy): Use prototype if __STDC__ is defined, not just
1196         if __cplusplus is defined.
1197
1198 2001-11-30  Akim Demaille  <akim@epita.fr>
1199
1200         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1201         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1202         Gettext doesn't compile cleanly, and dies with -Werror.
1203         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1204         Include WARNING_CFLAGS here.
1205         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1206         before being defined.
1207
1208 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1209
1210         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1211         First arg is int, not unsigned.
1212         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1213         (SIZE_MAX, UINT_MAX): New macros.
1214         (quotearg_n_options): Abort if N is negative.
1215         Avoid overflow check on hosts where size_t is 64 bits and int
1216         is 32 bits, as overflow is impossible there.
1217         Fix off-by-one typo that caused unnecessary reallocation.
1218
1219 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1220
1221         Name space cleanup in generated parser.
1222
1223         * doc/bison.texinfo (Bison Parser): Discuss system headers
1224         and their effect on the user name space.
1225
1226         * src/bison.simple:
1227         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1228         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1229         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1230
1231         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1232         on user names when possible.
1233
1234         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1235         Simplify test for whather <alloca.h> exists.
1236
1237         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1238
1239         (<stdio.h>): Include if YYDEBUG.
1240
1241         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1242         ! defined (yyoverflow) && ! defined (yymemcpy).
1243
1244         (yymemcpy, yyparse): Rename local variables as needed so that
1245         they all begin with 'yy'.
1246
1247         (yystrlen, yystpcpy): New functions.
1248
1249         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1250         All uses changed.
1251
1252         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1253         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1254         and YYSTACK_FREE instead of malloc and free.
1255
1256 2001-11-30  Akim Demaille  <akim@epita.fr>
1257
1258         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1259         before their first uses.
1260         (YYBISON, YYPURE): Move to the top of the output.

1265
1266 2001-11-30  Akim Demaille  <akim@epita.fr>
1267
1268         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1269         if body instead of `;' to pacify GCC's warnings.
1270
1271 2001-11-30  Akim Demaille  <akim@epita.fr>
1272
1273         Instead of mapping the LHS of unused rules to -1, keep the LHS
1274         valid, but flag the rules as invalid.
1275
1276         * src/gram.h (rule_t): `useful' is a new member.
1277         * src/print.c (print_grammar): Adjust.
1278         * src/derives.c (set_derives): Likewise.
1279         * src/reader.c (packgram, reduce_output): Likewise.
1280         * src/reduce.c (reduce_grammar_tables): Likewise.
1281         * tests/reduce.at (Underivable Rules, Useless Rules): New.
1282

1285         * src/reduce.c (reduce_output): Formatting changes.
1286         * src/print.c (print_results, print_grammar): Likewise.
1287         * tests/regression.at (Rule Line Numbers)
1288         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
1289
1290 2001-11-30  Akim Demaille  <akim@epita.fr>
1291
1292         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1293         useless nonterminals, move them at the end of the symbol arrays.
1294         (reduce_output): Adjust.
1295         * tests/reduce.at (Useless Nonterminals): Adjust.
1296
1297 2001-11-30  Akim Demaille  <akim@epita.fr>
1298
1299         * src/reduce.c: Various comment/formatting changes.
1300         (nonterminals_reduce): New, extracted from...
1301         (reduce_grammar_tables): here.
1302         (reduce_grammar): Call nonterminals_reduce.
1303
1304 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1305
1306         * src/bison.simple (YYSTACK_REALLOC): Remove.
1307         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1308         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1309         New macros.
1310         (union yyalloc): New type.
1311         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1312         an arbitrary restriction on hosts where size_t is wider than int.
1313
1314         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1315         a parser stack overflow.  Allocate just one block of memory for all
1316         three stacks, instead of allocating three blocks; this typically is
1317         faster and reduces fragmentation.
1318
1319         Do not limit the number of items in the stack to a value that fits
1320         in 'int', as this is an arbitrary limit on hosts with 64-bit
1321         size_t and 32-bit int.
1322
1323 2001-11-29  Marc Autret  <autret_m@epita.fr>
1324
1325         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
1326         of defining YYERROR_VERBOSE.

1329 2001-11-28  Marc Autret  <autret_m@epita.fr>

1340         (prepare): Echo name modification.
1341         * src/getargs.h: Clean its extern declaration.
1342         * src/getargs.c (error_verbose_flag): Remove.
1343         (getargs): Remove case 'e'.
1344         * src/options.c (option_table): 'error-verbose' is now seen as simple
1345         percent option.

1351         * src/options.c (option_table): 'include' is now a simple command line
1352         option.
1353
1354 2001-11-28  Marc Autret  <autret_m@epita.fr>
1355
1356         * src/bison.simple: Adjust muscle names.
1357         * src/muscle_tab.c (muscle_init): Also rename the muscles.
1358         * src/output.c (prepare): s/_/-/ for the muscles names.
1359         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
1360
1361 2001-11-28  Marc Autret  <autret_m@epita.fr>

1370
1371 2001-11-28  Akim Demaille  <akim@epita.fr>
1372
1373         * src/closure.c (closure): `b' and `ruleno' denote the same value:
1374         keep ruleno only.
1375
1376 2001-11-28  Akim Demaille  <akim@epita.fr>
1377
1378         * src/closure.c (closure): Instead of looping over word in array
1379         then bits in words, loop over bits in array.
1380
1381 2001-11-28  Akim Demaille  <akim@epita.fr>
1382
1383         * src/closure.c (closure): No longer optimize the special case
1384         where all the bits of `ruleset[r]' are set to 0, to make the code
1385         clearer.
1386
1387 2001-11-28  Akim Demaille  <akim@epita.fr>
1388
1389         * src/closure.c (closure): `r' and `c' are new variables, used to
1390         de-obfuscate accesses to RULESET and CORE.

1404         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
1405         as all tags are free'ed afterwards.
1406         From Enrico Scholz.
1407
1408 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1409
1410         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
1411         use alloca when we didn't want to, and vice versa.
1412

1520 2001-11-23  Akim Demaille  <akim@epita.fr>
1521
1522         Attaching lineno to buckets is stupid, since only one copy of each
1523         symbol is kept, only the line of the first occurrence is kept too.

1778         arg_offset.
1779         arg is const.

2750         bound to true.
2751         (read_declarations): Add case for macro definition.
2752         (copy_identifier): New.
2753         (parse_macro_decl): Read macro identifiers using copy_identifier

2788         with something new. Skeletons are now processed character by character

2790         first step in making Bison's output process (a lot) more flexible.
2791         (output_parser): Use the macro table.

3136         issues in Bison, it would mean way too much duplicate effort to
3137         import in Bison features implemented in 2.49c since 2.13.

3171         Since we now use obstacks, more % directives can be enabled.
3172
3173         * src/lex.c (percent_table): Also accept `%yacc',
3174         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3175         `%debug'.
3176         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3177         instead of returning a token.
3178         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3179         * src/reader.c (read_declarations): Adjust.
3180         * src/files.c (open_files): Don't call `compute_base_names', don't

3182         *in* the input file now.
3183         (output_files): Do it here.
3184         * src/output.c (output_headers): Document the fact that this patch

3210         FILE * parameters.
3211
3212 2000-12-20  Akim Demaille  <akim@epita.fr>
3213
3214         * src/files.c (open_files): Actually the `.output' file is based
3215         on the short_base_name, not base_name.
3216         * tests/suite.at (Checking output file names): Adjust.
3217
3218 2000-12-20  Akim Demaille  <akim@epita.fr>

3238         (base_name, short_base_name): Be global.

3244         (stringappend): Be just like strcat but allocate.
3245         (base_names): Eve out from open_files.
3246         Try to simplify the rather hairy computation of base_name and
3247         short_base_name.
3248         (open_files): Use it.
3249         * tests/suite.at (Checking output file names): New test.

3268
3269         Let the handling of the skeleton files be local to the procedures

3287 2000-12-19  Akim Demaille  <akim@epita.fr>
3288
3289         * src/files.c (open_files): Yipee!  We no longer need all the code

3320
3321         * lib/obstack.h: Formatting changes.
3322         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3323         prevents type checking.
3324         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3325         cast the value to (void *): assigning a `foo *' to a `void *'
3326         variable is valid.
3327         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3328         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3344
3345         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

3365

3390         For some reason, this was not applied.
3391

3408         * src/main.c (main): Don't use `atexit' to register `done', since
3409         it no longer has to remove tmp files, just call `output_files'
3410         when there are no errors.
3411
3412 2000-11-02  Akim Demaille  <akim@epita.fr>

3448         * src/files.c (faction): Remove.

3516         `bison -v' segfaults.
3517         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3518
3519         * tests/regression.m4: New file.
3520         Include the core of the sample provided by Piotr Gackiewicz.

3525
3526         * src/reader.c (parse_expect_decl): Keep `count' within the size

3530 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3531
3532         * bison.s1 (yyparse): Assign the default value
3533         unconditionally, to avoid a GCC warning and make the parser a
3534         tad smaller.
3535
3536 2000-10-02  Akim Demaille  <akim@epita.fr>
3537

3545
3546 2000-10-02  Akim Demaille  <akim@epita.fr>
3547
3548         The location tracking mechanism is precious for parse error
3549         messages.  Nevertheless, it is enabled only when `@n' is used in
3550         the grammar, which is a different issue (you can use it in error
3551         message, but not in the grammar per se).  Therefore, there should
3552         be another means to enable it.
3553
3554         * src/getargs.c (getargs): Support `--locations'.
3555         (usage): Report it.
3556         * src/getargs.h (locationsflag): Export it.
3557         * src/lex.c (percent_table): Support `%locations'.
3558         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3559         with `locationsflag'.
3560         * doc/bison.texinfo: Document `--locations' and `%locations'.
3561         Sort the options.
3562         * tests/calc.m4: Test it.
3563
3564         For regularity of the names, replace each
3565         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3566         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3567         In addition replace each `flag' with `_flag'.
3568
3569 2000-10-02  Akim Demaille  <akim@epita.fr>
3570
3571         Also test parse error messages, including with YYERROR_VERBOSE.
3572
3573         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3574         associative).
3575         Use it to check the computations.
3576         Use it to check `nonassoc' is honored.
3577         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3578         `--yyerror-verbose'.
3579         (_AT_CHECK_CALC): Adjust to this option.
3580         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3581
3582 2000-10-02  Akim Demaille  <akim@epita.fr>
3583
3584         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3585         the latter demonstrates a flaw in the handling of non debugging
3586         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3587         was used in order to simplify:
3588
3589         #if YYDEBUG
3590         if (yydebug)
3591         {
3592         ...
3593         }
3594         #endif

3599         {
3600         ...

3602
3603         unfortunately this leads to a CPP conflict when
3604         `--name-prefix=foo' is used since it produces `#define yydebug
3605         foodebug'.
3606
3607         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3608         (YYDPRINTF): New macro.
3609         Spread its use.

3611         the bison options.

3620         (yydefault): Don't fall through to `yyresume': `goto' there.
3621         * src/output.c (output_parser): When the `$' is met, skip the end
3622         of its line.
3623         New variable, `number_of_dollar_signs', to check there's exactly
3624         one `$' in the parser skeleton.
3625
3626 2000-10-02  Akim Demaille  <akim@epita.fr>
3627

3630         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3631         instead of strlen + xmalloc + strcpy.

3633
3634 2000-10-02  Akim Demaille  <akim@epita.fr>
3635
3636         * src/gram.h (associativity): New enum type which replaces the
3637         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3638         `right_assoc', `left_assoc' and `non_assoc'.
3639         Adjust all dependencies.
3640         * src/reader.c: Formatting changes.
3641         (LTYPESTR): Don't define it, use it as a literal in
3642         `reader_output_yylsp'.
3643         * src/symtab.h (symbol_class): New enum type which replaces the
3644         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3645         `sunknown', `stoken and `snterm'.

3652
3653 2000-10-02  Akim Demaille  <akim@epita.fr>
3654
3655         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3656         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3657         difficult and introduced a lot of core dump.  It turns out that
3658         Bison used an implementation of `xmalloc' based on `calloc', and
3659         at various places it does depend upon the initialization to 0.  I
3660         have not tried to isolate the pertinent places, and all the former
3661         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3662         someone should address this issue.
3663
3664         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3665         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

3678
3679         * src/state.h (nstates, final_state, first_state, first_shift)

3758
3759         * src/output.c (token_actions): Introduce a temporary array,
3760         YYDEFACT, that makes it possible for this function to use
3761         output_short_table.
3762
3763 2000-10-02  Akim Demaille  <akim@epita.fr>
3764
3765         `user_toknums' is output as a `short[]' in `output.c', while it is
3766         defined as a `int[]' in `reader.c'.  For consistency with the
3767         other output tables, `user_toknums' is now defined as a table of
3768         shorts.
3769
3770         * src/reader.c (user_toknums): Be a short table instead of an int
3771         table.

3783         order to get rid of the `static' prototypes.
3784         No longer use `register'.
3785         * src/output.h: New file.
3786         Propagate its inclusion in files explicitly prototyping functions
3787         from output.c.

3809         inclusion.
3810         Don't define PARAMS.
3811         * src/system.h: Define PARAMS.
3812         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3813         purpose of config.h.  system.h must not try to fix wrong
3814         definitions in config.h.

3976         the file name, not the whole `#line LINE FILE'.
3977
3978 2000-03-17  Akim Demaille  <akim@epita.fr>
3979
3980         On syntax errors, report the token on which we choked.

4002         copy_comment.  Removed now unused `match', `ended',
4003         `cplus_comment'.
4004         (copy_comment, copy_string): Moved, to be visible from
4005         copy_definition.

4031
4032         Change the handling of @s so that they behave exactly like $s.
4033         There is now a pseudo variable @$ (readble and writable), location
4034         of the lhs of the rule (by default ranging from the location of
4035         the first symbol of the rhs, to the location of the last symbol,
4036         or, if the rhs is empty, YYLLOC).
4037

4039         yyval.
4040         (yyparse): When providing a default semantic action, provide a
4041         default location action.
4042         (after the $): No longer change `*YYLSP', just stack YYLOC the
4043         same way you stack YYVAL.
4044         * src/reader.c (read_declarations): Use warns.
4045         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4046         (copy_action, case '@'): Likewise.
4047         Use a standard error message, to save useless work from
4048         translators.
4049
4050 2000-03-17  Akim Demaille  <akim@epita.fr>

4069
4070         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4071         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4072         One `#if YYDEBUG' remains, since it uses variables which are
4073         defined only if `YYDEBUG != 0'.
4074
4075 2000-03-16  Akim Demaille  <akim@epita.fr>

4101         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

4107         the proper line number and file name.
4108         (DEFS): Propagate the location of bison library files and of the
4109         locale files.
4110         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4111         builddir.
4112         * acinclude.m4: Remove, replaced by the directory m4.
4113         * m4/Makefile.am (EXTRA_DIST): New variable.

4746         (readgram): Use `#if 0' around code that accepted %command
4747         inside grammar rules:  The documentation doesn't allow it,

4760         (get_type, packsymbols):  Revised most error messages.
4761         Changed `fatal' to `warnxxx' to avoid aborting for error.
4762         Revised and use multiple warnxxx functions to avoid using VARARGS1.
4763         (read_declarations): Improve the error message for
4764         an invalid character.  Do not abort.
4765         (read_declarations, copy_guard, copy_action): Use
4766         printable_version to avoid unprintable characters in printed output.

4778         * src/main.c (main):
4779          If reader sees an error, don't process the grammar.
4780         (fatals): Updated to not use VARARGS1.
4781         (printable_version, int_to_string, warn, warni, warns, warnss)
4782         (warnsss): New error reporting functions.  Avoid abort for error.
4783
4784         * src/lex.h:

4798         (parse_percent_token): Added % declarations as another
4799         way to specify the flags -n, -l, and -r.  Also added hooks for
4800         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4801         major changes to files.c.
4802         (lex) Retain in the incoming stream a character following
4803         an incorrect '/'.
4804         (skip_white_space, lex):  Revised most error messages
4805         and changed fatal to warn to avoid aborting.
