ChangeLog

   1 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
   2
   3         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
   4         (MUSCLE_INSERT_PREFIX): ...to there.
   5         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
   6         (MUSCLE_INSERT_PREFIX): Move from here...
   7
   8         * src/bison.hairy: Add a section directive.  Put braces around muscle
   9         names.  This parser skeleton is still broken, but Bison should not
  10         choke on a bad muscle 'syntax'.
  11         * src/bison.simple: Add a section directive.  Put braces around muscle
  12         names.
  13
  14         * src/files.h (strsuffix, stringappend): Add declarations.
  15         (tab_extension): Add declaration.
  16         (short_base_name): Add declaration.
  17
  18         * src/files.c (strsuffix, stringappend): No longer static.  These
  19         functions are used in the skeleton parser.
  20         (tab_extension): New.
  21         (compute_base_names): Use the computations done in this function
  22         to guess if the generated parsers should have '.tab' in their
  23         names.
  24         (short_base_name): No longer static.
  25
  26         * src/output.c (output_skeleton): New.
  27         (output): Disable call to output_master_parser, and give a try to
  28         a new skeleton handling system.
  29         (guards_output, actions_output): No longer static.
  30         (token_definitions_output, get_lines_number): No longer static.
  31
  32         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
  33
  34         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
  35         parse-skel.y.
  36
  37         * src/parse-skel.y: New file.
  38         * src/scan-skel.l: New file.
  39
  40 2001-12-29  Akim Demaille  <akim@epita.fr>
  41
  42         %name-prefix is broken.
  43
  44         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
  45         Adjust all dependencies.
  46         * tests/headers.at (export YYLTYPE): Strengthen this test: use
  47         %name-prefix.
  48
  49         Renaming yylval but not yylloc is not consistent.  Now we do.
  50
  51         * src/bison.simple: Prefix yylloc if used.
  52         * doc/bison.texinfo (Decl Summary): Document that.
  53
  54 2001-12-29  Akim Demaille  <akim@epita.fr>
  55
  56         * doc/bison.texinfo: Promote `%long-directive' over
  57         `%long_directive'.
  58         Remove all references to fixed-output-files, yacc is enough.
  59
  60 2001-12-29  Akim Demaille  <akim@epita.fr>
  61
  62         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
  63         user prologue.  These are defaults.
  64         * tests/actions.at (Mid-rule actions): Make sure the user can
  65         define YYDEBUG and YYERROR_VERBOSE.
  66
  67 2001-12-29  Akim Demaille  <akim@epita.fr>
  68
  69         * src/output.c (header_output): Don't forget to export YYLTYPE and
  70         yylloc.
  71         * tests/headers.at (export YYLTYPE): New, make sure it does.
  72         * tests/regression.at (%union and --defines, Invalid CPP headers):
  73         Move to...
  74         * tests/headers.at: here.
  75
  76 2001-12-29  Akim Demaille  <akim@epita.fr>
  77
  78         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
  79
  80 2001-12-29  Akim Demaille  <akim@epita.fr>
  81
  82         * tests/actions.at (Mid-rule actions): Output on a single line
  83         instead of several.
  84
  85 2001-12-29  Akim Demaille  <akim@epita.fr>
  86
  87         * doc/bison.texinfo: Formatting changes.
  88
  89 2001-12-29  Akim Demaille  <akim@epita.fr>
  90
  91         Don't store the token defs in a muscle, just be ready to output it
  92         on command.  Now possible via `symbols'.  Fixes a memory leak.
  93
  94         * src/output.c (token_definitions_output): New.
  95         (output_parser, header_output): Use it.
  96         * src/reader.c (symbols_save): Remove.
  97
  98 2001-12-29  Akim Demaille  <akim@epita.fr>
  99
 100         * src/bison.simple: Do not provide a default for YYSTYPE and
 101         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 102         default.
 103
 104 2001-12-29  Akim Demaille  <akim@epita.fr>
 105
 106         Mid-rule actions are simply... ignored!
 107
 108         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 109         the empty-rule associated to the dummy symbol, not to the host
 110         rule.
 111         * tests/actions.at (Mid-rule actions): New.
 112
 113 2001-12-29  Akim Demaille  <akim@epita.fr>
 114
 115         Memory leak.
 116
 117         * src/reader.c (reader): Free grammar.
 118
 119 2001-12-29  Akim Demaille  <akim@epita.fr>
 120
 121         Memory leak.
 122
 123         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 124         since it allocates it for each state, although only one is needed.
 125         (allocate_storage): Do it here.
 126
 127 2001-12-29  Akim Demaille  <akim@epita.fr>
 128
 129         * src/options.h, src/options.c (create_long_option_table): Rename
 130         as...
 131         (long_option_table_new): this, with a clearer prototype.
 132         (percent_table): Remove, unused,
 133         * src/getargs.c (getargs): Adjust.
 134
 135 2001-12-29  Akim Demaille  <akim@epita.fr>
 136
 137         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 138         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 139         as states.
 140
 141 2001-12-29  Akim Demaille  <akim@epita.fr>
 142
 143         * src/lalr.c (build_relations): Rename `states' as `states1'.
 144         Sorry, I don't understand exactly what it is, no better name...
 145
 146 2001-12-29  Akim Demaille  <akim@epita.fr>
 147
 148         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 149         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 150         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 151         as rules.
 152
 153 2001-12-29  Akim Demaille  <akim@epita.fr>
 154
 155         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 156         ago.
 157
 158 2001-12-29  Akim Demaille  <akim@epita.fr>
 159
 160         * src/reader.c, src/reader.h (user_toknums): Remove.
 161         Adjust all users to use symbols[i]->user_token_number.
 162
 163 2001-12-29  Akim Demaille  <akim@epita.fr>
 164
 165         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 166         Adjust all users to use symbols[i]->prec or ->assoc.
 167
 168 2001-12-29  Akim Demaille  <akim@epita.fr>
 169
 170         * src/reader.c, src/reader.h (tags): Remove.
 171         Adjust all users to use symbols[i]->tag.
 172
 173 2001-12-29  Akim Demaille  <akim@epita.fr>
 174
 175         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 176         and rule_table.
 177         * src/reader.c (packsymbols): Fill this table.
 178         Drop sprec.
 179         * src/conflicts.c (resolve_sr_conflict): Adjust.
 180         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 181         single table.
 182         Use symbols[i]->tag instead of tags[i].
 183
 184 2001-12-29  Akim Demaille  <akim@epita.fr>
 185
 186         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 187         In addition, put a comment in there, to replace...
 188         * tests/regression.at (%union and C comments): Remove.
 189
 190 2001-12-29  Akim Demaille  <akim@epita.fr>
 191
 192         * tests/regression.at (Web2c Actions): Blindly move the actual
 193         output as expected output.  The contents *seem* right to me, but I
 194         can't pretend reading perfectly parser tables...  Nonetheless, all
 195         the other tests pass correctly, the table look OK, even though the
 196         presence of `$axiom' is to be noted: AFAICS it is useless (but
 197         harmless).
 198
 199 2001-12-29  Akim Demaille  <akim@epita.fr>
 200
 201         * src/reader.c (readgram): Don't add the rule 0 if there were no
 202         rules read.  In other words, add it _after_ having performed
 203         grammar sanity checks.
 204         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 205
 206 2001-12-29  Akim Demaille  <akim@epita.fr>
 207
 208         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 209         visible, and some states have now a different number.
 210
 211 2001-12-29  Akim Demaille  <akim@epita.fr>
 212
 213         * src/reader.c (readgram): Bind the initial rule's lineno to that
 214         of the first rule.
 215         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 216         (Solved SR Conflicts): Adjust rule 0's line number.
 217
 218 2001-12-29  Akim Demaille  <akim@epita.fr>
 219
 220         Fix the `GAWK Grammar' failure.
 221
 222         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 223         the reductions of the first state which was mistakenly confused
 224         with the final state because precisely final_state was initialized
 225         to 0.
 226         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 227         now noticed by Bison.
 228         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 229         have a reduction on $default.
 230
 231 2001-12-29  Akim Demaille  <akim@epita.fr>
 232
 233         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 234         rule line numbers.
 235         * src/closure.c (print_closure): Likewise.
 236         * src/derives.c (print_derives): Likewise.
 237         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 238         now.
 239
 240 2001-12-29  Akim Demaille  <akim@epita.fr>
 241
 242         * src/lalr.c (lookaheads_print): New.
 243         (lalr): Call it when --trace-flag.
 244         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 245         are dumped.
 246
 247 2001-12-29  Akim Demaille  <akim@epita.fr>
 248
 249         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 250         when walking through ritem, even via rule->rhs.
 251         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 252         (useful_production, useless_nonterminals): Likewise.
 253         (reduce_grammar_tables): Likewise, plus update nritems.
 254         * src/nullable.c (set_nullable): Likewise.
 255         * src/lalr.c (build_relations): Likewise.
 256         * tests/sets.at (Nullable): Adjust.
 257         Fortunately, now, the $axiom is no longer nullable.
 258
 259 2001-12-29  Akim Demaille  <akim@epita.fr>
 260
 261         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 262         the 0-sentinel.
 263         * src/gram.c (ritem_longest_rhs): Likewise.
 264         * src/reduce.c (nonterminals_reduce): Likewise.
 265         * src/print_graph.c (print_graph): Likewise.
 266         * src/output.c (output_rule_data): Likewise.
 267         * src/nullable.c (set_nullable):  Likewise.
 268
 269 2001-12-29  Akim Demaille  <akim@epita.fr>
 270
 271         * src/output.c: Comment changes.
 272
 273 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 274
 275         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 276         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 277         Sparc, as they were causing more porting problems than the
 278         (minor) performance improvement was worth.
 279
 280         Also, catch up with 1.31's YYSTD.
 281
 282 2001-12-27  Akim Demaille  <akim@epita.fr>
 283
 284         * src/output.c (output_gram): Rely on nritems, not the
 285         0-sentinel.  See below.
 286         Use -1 as separator, not 0.
 287         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 288         Rely on -1 as separator in yyrhs, instead of 0.
 289         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 290         twice `Now at end of input', therefore there are two lines less to
 291         expect.
 292
 293 2001-12-27  Akim Demaille  <akim@epita.fr>
 294
 295         * tests/regression.at (Unresolved SR Conflicts):
 296         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 297         below.
 298
 299 2001-12-27  Akim Demaille  <akim@epita.fr>
 300
 301         * src/LR0.c (new_state): Recognize the final state by the fact it
 302         is reached by eoftoken.
 303         (insert_start_shifting_state, insert_eof_shifting_state)
 304         (insert_accepting_state, augment_automaton): Remove, since now
 305         these states are automatically computed from the initial state.
 306         (generate_states): Adjust.
 307         * src/print.c: When reporting a rule number to the user, substract
 308         1, so that the axiom rule is rule 0, and the first user rule is 1.
 309         * src/reduce.c: Likewise.
 310         * src/print_graph.c (print_core): For the time being, just as for
 311         the report, depend upon --trace-flags to dump the full set of
 312         items.
 313         * src/reader.c (readgram): Once the grammar read, insert the rule
 314         0: `$axiom: START-SYMBOL $'.
 315         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 316         number of the states has changed (the final state is no longer
 317         necessarily the last), catch up.
 318
 319 2001-12-27  Akim Demaille  <akim@epita.fr>
 320
 321         Try to make the use of the eoftoken valid.  Given that its value
 322         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 323         is used instead of > 0 where appropriate, (ii), depend upon nritems
 324         instead of the 0-sentinel.
 325
 326         * src/gram.h, src/gram.c (nritems): New.
 327         Expected to be duplication of nitems, but for the time being...
 328         * src/reader.c (packgram): Assert nritems and nitems are equal.
 329         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 330         * src/closure.c (print_closure, print_fderives): Likewise.
 331         * src/gram.c (ritem_print): Likewise.
 332         * src/print.c (print_core, print_grammar): Likewise.
 333         * src/print_graph.c: Likewise.
 334
 335 2001-12-27  Akim Demaille  <akim@epita.fr>
 336
 337         * src/main.c (main): If there are complains after grammar
 338         reductions, then output the report anyway if requested, then die.
 339         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 340         * src/reader.c (eoftoken): New.
 341         (parse_token_decl): If the token being defined has value `0', it
 342         is the eoftoken.
 343         (packsymbols): No longer hack `tags' to insert `$' by hand.
 344         Be sure to preserve the value of the eoftoken.
 345         (reader): Make sure eoftoken is defined.
 346         Initialize nsyms to 0: now eoftoken is created just like the others.
 347         * src/print.c (print_grammar): Don't special case the eof token.
 348         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 349         lie anyway, albeit pleasant.
 350         * tests/calc.at: Exercise error messages with eoftoken.
 351         Change the grammar so that empty input is invalid.
 352         Adjust expectations.
 353         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 354
 355 2001-12-27  Akim Demaille  <akim@epita.fr>
 356
 357         * configure.in: Check the protos of strchr ans strspn.
 358         Replace strchr if needed.
 359         * src/system.h: Provide the protos of strchr, strspn and memchr if
 360         missing.
 361         * lib/strchr.c: New.
 362         * src/reader.c (symbols_save): Use strchr.
 363
 364 2001-12-27  Akim Demaille  <akim@epita.fr>
 365
 366         * src/print.c, src/print_graph.c (escape): New.
 367         Use it to quote the TAGS outputs.
 368         * src/print_graph.c (print_state): Now errors are in red, and
 369         reductions in green.
 370         Prefer high to wide: output the state number on a line of its own.
 371
 372 2001-12-27  Akim Demaille  <akim@epita.fr>
 373
 374         * src/state.h, src/state.c (reductions_new): New.
 375         * src/LR0.c (set_state_table): Let all the states have a
 376         `reductions', even if reduced to 0.
 377         (save_reductions): Adjust.
 378         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 379         * src/print.c (print_reductions, print_actions): Adjust.
 380         * src/output.c (action_row): Adjust.
 381
 382 2001-12-27  Akim Demaille  <akim@epita.fr>
 383
 384         * src/state.h, src/state.c (errs_new, errs_dup): New.
 385         * src/LR0.c (set_state_table): Let all the states have an errs,
 386         even if reduced to 0.
 387         * src/print.c (print_errs, print_reductions): Adjust.
 388         * src/output.c (output_actions, action_row): Adjust.
 389         * src/conflicts.c (resolve_sr_conflict): Adjust.

 391 2001-12-27  Akim Demaille  <akim@epita.fr>
 392
 393         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 394
 395 2001-12-27  Akim Demaille  <akim@epita.fr>
 396
 397         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 398         * src/print.c: here.
 399         (lookaheadset, shiftset): New, used as additional storage by
 400         print_reductions.
 401         (print_results): Adjust.
 402         (print_shifts, print_gotos, print_errs): New, extracted from...
 403         (print_actions): here.
 404         * src/print_graph.c (print_actions): Remove dead code.
 405
 406 2001-12-27  Akim Demaille  <akim@epita.fr>
 407
 408         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 409         `$n' and `@n'.
 410
 411 2001-12-27  Akim Demaille  <akim@epita.fr>
 412
 413         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 414         (build_relations): Adjust.
 415
 416 2001-12-27  Akim Demaille  <akim@epita.fr>
 417
 418         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 419         duplication.
 420
 421 2001-12-27  Akim Demaille  <akim@epita.fr>
 422
 423         * src/reader.c (packgram): Catch nitems overflows.
 424
 425 2001-12-27  Akim Demaille  <akim@epita.fr>
 426
 427         * src/files.c, src/files.h (guard_obstack): Remove.
 428         * src/output.c (output): Adjust.
 429         * src/reader.c (parse_braces): New, factoring...
 430         (copy_action, copy_guard): these two which are renamed as...
 431         (parse_action, parse_guard): these.
 432         As a voluntary consequence, using braces around guards is now
 433         mandatory.
 434
 435 2001-12-27  Akim Demaille  <akim@epita.fr>
 436
 437         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 438         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 439         members.
 440         (symbol_list_new): Adjust.
 441         (copy_action): action_line is the first line, not the last.
 442         (copy_guard): Just as for actions, store the `action' only, not
 443         the switch/case/break flesh.
 444         Don't parse the user action that might follow the guard, let...
 445         (readgram): do it, i.e., now, there can be an action after a
 446         guard.
 447         In other words the guard is just explicitly optional.
 448         (packgram): Adjust.
 449         * src/output.c (guards_output): New.
 450         (output_parser): Call it when needed.
 451         (output): Also free the guard and attrs obstacks.
 452         * src/files.c, src/files.h (obstack_save): Remove.
 453         (output_files): Remove.
 454         As a result, if one needs the former `.act' file, using an
 455         appropriate skeleton which requires actions and guards is now
 456         required.
 457         * src/main.c (main): Adjust.
 458         * tests/semantic.at: New.
 459         * tests/regression.at: Use `input.y' as input file name.
 460         Avoid 8+3 problems by requiring input.c when the test needs the
 461         parser.
 462
 463 2001-12-27  Akim Demaille  <akim@epita.fr>
 464
 465         * src/reader.c (symbol_list_new): Be sure to initialize all the
 466         fields.
 467
 468 2001-12-27  Akim Demaille  <akim@epita.fr>
 469
 470         All the hacks using a final pseudo state are now useless.
 471
 472         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 473         * src/lalr.c (nLA): New.
 474         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 475         instead of lookaheadsp from the pseudo state (nstate + 1).
 476
 477 2001-12-27  Akim Demaille  <akim@epita.fr>
 478
 479         * src/output.c (action_row, token_actions): Use a state_t instead
 480         of a integer, and nlookaheads instead of the following state's
 481         lookaheadsp.
 482
 483 2001-12-27  Akim Demaille  <akim@epita.fr>
 484
 485         * src/conflicts.c (log_resolution, flush_shift)
 486         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 487         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 488         (conflicts_print, print_reductions): Use a state_t instead of an
 489         integer when referring to a state.
 490         As much as possible, depend upon nlookaheads, instead of the
 491         `lookaheadsp' member of the following state (since lookaheads of
 492         successive states are successive, the difference between state n + 1
 493         and n served as the number of lookaheads for state n).
 494         * src/lalr.c (add_lookback_edge): Likewise.
 495         * src/print.c (print_core, print_actions, print_state)
 496         (print_results): Likewise.
 497         * src/print_graph.c (print_core, print_actions, print_state)
 498         (print_graph): Likewise.
 499         * src/conflicts.h: Adjust.

 501 2001-12-27  Akim Demaille  <akim@epita.fr>
 502
 503         * src/bison.hairy: Formatting/comment changes.
 504         ANSIfy.
 505         Remove `register' indications.
 506         Add plenty of `static'.
 507
 508 2001-12-27  Akim Demaille  <akim@epita.fr>
 509
 510         * src/output.c (prepare): Drop the muscle `ntbase' which
 511         duplicates ntokens.
 512         * src/bison.simple: Formatting/comment changes.
 513         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 514         is an undocumented synonym.
 515
 516 2001-12-22  Akim Demaille  <akim@epita.fr>
 517
 518         * src/output.c (output_table_data): Change the prototype to use
 519         `int' for array ranges: some invocations do pass an int, not a
 520         short.
 521         Reported by Wayne Green.
 522
 523 2001-12-22  Akim Demaille  <akim@epita.fr>
 524
 525         Some actions of web2c.y are improperly triggered.
 526         Reported by Mike Castle.
 527
 528         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 529         * tests/regression.at (Web2c): Rename as...
 530         (Web2c Report): this.
 531         (Web2c Actions): New.
 532
 533 2001-12-22  Akim Demaille  <akim@epita.fr>
 534
 535         Reductions in web2c.y are improperly reported.
 536         Reported by Mike Castle.
 537
 538         * src/conflicts.c (print_reductions): Fix.
 539         * tests/regression.at (Web2c): New.
 540
 541 2001-12-18  Akim Demaille  <akim@epita.fr>
 542
 543         Some host fail on `assert (!"foo")', which expands to
 544         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 545         Reported by Nelson Beebee.
 546
 547         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 548         `#define it_succeeded 0' and `assert (it_succeeded)'.
 549
 550 2001-12-17  Marc Autret  <autret_m@epita.fr>
 551
 552         * src/bison.simple: Don't hard code the skeleton line and filename.
 553         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 554         New line counter 'skeleton_line' (skeleton-line muscle).
 555
 556 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 557
 558         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 559         YYDEBUG must be defined to a nonzero value.
 560
 561         * src/bison.simple (yytname): Do not assume that the user defines
 562         YYDEBUG to a properly parenthesized expression.
 563
 564 2001-12-17  Akim Demaille  <akim@epita.fr>
 565
 566         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 567         nlookaheads is a new member.
 568         Adjust all users.
 569         * src/lalr.h (nlookaheads): Remove this orphan declaration.
 570         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 571         state.
 572
 573 2001-12-17  Akim Demaille  <akim@epita.fr>
 574
 575         * src/files.h, src/files.c (open_files, close_files): Remove.
 576         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 577         let...

 583
 584 2001-12-17  Akim Demaille  <akim@epita.fr>
 585
 586         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 587         (flush_reduce): New.
 588         (resolve_sr_conflict): Adjust.
 589
 590 2001-12-17  Akim Demaille  <akim@epita.fr>
 591
 592         * src/output.c (output_obstack): Be static and rename as...
 593         (format_obstack): this, to avoid any confusion with files.c's
 594         output_obstack.
 595         * src/reader.h (muscle_obstack): Move to...
 596         * src/output.h: here, since it's defined in output.c.
 597
 598 2001-12-17  Akim Demaille  <akim@epita.fr>
 599
 600         * src/output.c (action_row, save_column, default_goto)

 607
 608 2001-12-17  Akim Demaille  <akim@epita.fr>
 609
 610         * src/files.c (output_files): Free the output_obstack.
 611         * src/main.c (main): Call print and print_graph conditionally.
 612         * src/print.c (print): Work unconditionally.

 616 2001-12-16  Marc Autret  <autret_m@epita.fr>
 617

 619         there is one less line per action.
 620
 621 2001-12-16  Marc Autret  <autret_m@epita.fr>
 622
 623         * src/bison.simple: Remove a useless #line directive.
 624         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 625         * src/output.c (get_lines_number): New.
 626         (output_parser): Adjust, now takes care about the lines of a
 627         output muscles.
 628         Fix line numbering.
 629         (actions_output): Computes the number of lines taken by actions.
 630         (output_master_parser): Insert new skeleton which is the name of
 631         the output parser file name.
 632
 633 2001-12-15  Marc Autret  <autret_m@epita.fr>
 634

 640
 641 2001-12-15  Akim Demaille  <akim@epita.fr>
 642
 643         Make `make distcheck' work.
 644
 645         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 646         system.h which uses libgettext.h.
 647
 648 2001-12-15  Akim Demaille  <akim@epita.fr>
 649
 650         * src/nullable.c (set_nullable): Useless rules must be skipped,
 651         otherwise, since we range over their symbols, we might look at a
 652         nonterminal which no longer ``exists'', i.e., it is not counted in
 653         `nvars', hence we overflow our arrays.
 654
 655 2001-12-15  Akim Demaille  <akim@epita.fr>
 656
 657         The header can also be produced directly, without any obstack!
 658         Yahoo!
 659
 660         * src/files.c, src/files.h (defines_obstack): Remove.
 661         (compute_header_macro): Global.
 662         (defines_obstack_save): Remove.
 663         * src/reader.c (parse_union_decl): No longer output to
 664         defines_obstack: its content can be found in the `stype' muscle
 665         anyway.
 666         (output_token_translations): Merge into...
 667         (symbols_output): this.
 668         Rename as...

 673
 674 2001-12-15  Akim Demaille  <akim@epita.fr>
 675
 676         * src/reader.c (parse_union_decl): Instead of handling two obstack
 677         simultaneously, use one to define the `stype' muscle, and use the
 678         value of the latter to fill defines_obstack.
 679         (copy_comment): Remove.
 680         (copy_comment2): Work for a single obstack.
 681         Rename as...
 682         (copy_comment): this.
 683
 684 2001-12-15  Akim Demaille  <akim@epita.fr>
 685
 686         * src/lex.c, src/lex.h (xgetc): No longer static.
 687         * src/reader.c (parse_union_decl): Revamp.
 688
 689 2001-12-15  Akim Demaille  <akim@epita.fr>
 690
 691         Still making progress in separating Bison into (i) input, (ii)
 692         process, (iii) output: now we can directly output the parser file
 693         without using table_obstack at all.
 694
 695         * src/files.c, src/files.h (table_obstack): Bye bye.
 696         (parser_file_name): New.
 697         * src/files.c (compute_output_file_names): Compute it.
 698         * src/output.c (actions_output, output_parser)
 699         (output_master_parser): To a file instead of an obstack.
 700
 701 2001-12-15  Akim Demaille  <akim@epita.fr>
 702
 703         Attach actions to rules, instead of pre-outputting them to
 704         actions_obstack.
 705
 706         * src/gram.h (rule_t): action and action_line are new members.
 707         * src/reader.c (symbol_list): Likewise.
 708         (copy_action): Save the actions within the rule.
 709         (packgram): Save them in rule_table.
 710         * src/output.c (actions_output): New.
 711         (output_parser): Use it on `%%actions'.
 712         (output_rule_data): Don't free rule_table.
 713         (output): Do it.
 714         (prepare): Don't save the `action' muscle.
 715         * src/bison.simple: s/%%action/%%actions/.
 716
 717 2001-12-15  Akim Demaille  <akim@epita.fr>
 718
 719         * src/reader.c (copy_action): When --yacc, don't append a `;'
 720         to the user action: let it fail if lacking.
 721         Suggested by Arnold Robbins and Tom Tromey.
 722
 723 2001-12-14  Akim Demaille  <akim@epita.fr>
 724
 725         * src/lex.c (literalchar): Simply return the char you decoded, non
 726         longer mess around with obstacks and int pointers.
 727         Adjust all callers.
 728
 729 2001-12-14  Akim Demaille  <akim@epita.fr>
 730
 731         * src/lex.c (literalchar): Don't escape the special characters,
 732         just decode them, and keep them as char (before, eol was output as
 733         the 2 char string `\n' etc.).
 734         * src/output.c (output_rule_data): Use quotearg to output the
 735         token strings.
 736
 737 2001-12-13  Paul Eggert  <eggert@twinsun.com>
 738
 739         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
 740         Do not infringe on the global user namespace when using C++.
 741         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
 742         All uses of `fprintf' and `stderr' changed.
 743
 744         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
 745
 746 2001-12-13  Akim Demaille  <akim@epita.fr>
 747
 748         The computation of nullable is broken: it doesn't handle empty
 749         RHS's properly.
 750
 751         * tests/torture.at (GNU AWK Grammar): New.
 752         * tests/sets.at (Nullable): New.
 753         * src/nullable.c (set_nullable): Instead of blindly looping over
 754         `ritems', loop over the rules, and then over their rhs's.
 755
 756         Work around Autotest bugs.
 757
 758         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
 759         frame, because Autotest understand lines starting with a `+' as
 760         traces from the shell.  Then, they are not processed properly.
 761         Admittedly an Autotest bug, but we don't have time to wait for
 762         Autotest to catch up.
 763         * tests/regression.at (Broken Closure): Adjust to the new table
 764         frames.
 765         Move to...
 766         * tests/sets.at: here.
 767
 768 2001-12-13  Akim Demaille  <akim@epita.fr>
 769
 770         * src/closure.c (closure): Use nrules instead of playing tricks
 771         with BITS_PER_WORD.
 772
 773 2001-12-13  Akim Demaille  <akim@epita.fr>
 774
 775         * src/print.c (print_actions): Output the handling of `$' as the
 776         traces do: shifting the token EOF.  Before EOF was treated as a
 777         nonterminal.
 778         * tests/regression.at: Adjust some tests.
 779         * src/print_graph.c (print_core): Complete the set of items via
 780         closure.  The next-to-final and final states are still unsatisfying,
 781         but that's to be addressed elsewhere.
 782         No longer output the rule numbers, but do output the state number.
 783         A single loop for the shifts + gotos is enough, but picked a
 784         distinct color for each.
 785         (print_graph): Initialize and finalize closure.
 786
 787 2001-12-13  Akim Demaille  <akim@epita.fr>
 788
 789         * src/reader.c (readgram): Remove dead code, an strip useless
 790         braces.
 791         (get_type): Remove, unused.
 792
 793 2001-12-12  Akim Demaille  <akim@epita.fr>
 794
 795         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 796         on that of lib/error.c.
 797
 798 2001-12-12  Akim Demaille  <akim@epita.fr>
 799
 800         Some hosts don't like `/' in includes.
 801
 802         * src/system.h: Include libgettext.h without qualifying the path.
 803         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 804         $(top_srcdir).
 805
 806 2001-12-11  Marc Autret  <autret_m@epita.fr>
 807
 808         * src/output.c (output_parser): Remove useless muscle.
 809
 810 2001-12-11  Marc Autret  <autret_m@epita.fr>
 811
 812         * src/bison.simple: Remove #line just before %%epilogue. It
 813         is now handled in ...
 814         * src/reader.c (read_additionnal_code): Add the output of a
 815         #line for the epilogue.
 816
 817 2001-12-10  Marc Autret  <autret_m@epita.fr>
 818
 819         * src/reader.c (copy_definition): Re-use CPP-outed code which
 820         replace precedent remove.
 821         * src/bison.simple: Remove #line before %%prologue because
 822         %%input-line is wrong at this time.
 823
 824 2001-12-10  Marc Autret  <autret_m@epita.fr>
 825
 826         * src/reader.c (symbols_output): Clean up.
 827         * src/output.c (output_gram, output): Clean up.
 828
 829 2001-12-10  Akim Demaille  <akim@epita.fr>
 830
 831         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 832         * src/LR0.c (set_state_table): here.
 833         * src/lalr.c (lalr): Call it.
 834
 835 2001-12-10  Akim Demaille  <akim@epita.fr>
 836
 837         * src/state.h (shifts): Remove the `number' member: shifts are
 838         attached to state, hence no longer need to be labelled with a
 839         state number.
 840
 841 2001-12-10  Akim Demaille  <akim@epita.fr>
 842
 843         Now that states have a complete set of members, the linked list of
 844         shifts is useless: just fill directly the state's shifts member.
 845
 846         * src/state.h (shifts): Remove the `next' member.
 847         * src/LR0.c (first_state, last_state): Remove.
 848         Adjust the callers.
 849         (augment_automaton): Don't look for the shifts that must be added
 850         a shift on EOF: it is those of the state we looked for!  But now,
 851         since shifts are attached, it is no longer needed to looking
 852         merely by its id: its number.
 853
 854 2001-12-10  Akim Demaille  <akim@epita.fr>
 855
 856         * src/LR0.c (augment_automaton): Better variable locality.
 857         Remove an impossible branch: if there is a state corresponding to
 858         the start symbol being shifted, then there is shift for the start
 859         symbol from the initial state.
 860
 861 2001-12-10  Akim Demaille  <akim@epita.fr>
 862
 863         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 864         only when appropriate: when insert_start_shifting_state' is not
 865         invoked.
 866         * tests/regression.at (Rule Line Numbers): Adjust.
 867
 868 2001-12-10  Akim Demaille  <akim@epita.fr>
 869
 870         * src/LR0.c (augment_automaton): Now that all states have shifts,
 871         merge the two cases addition shifts to the initial state.
 872
 873 2001-12-10  Akim Demaille  <akim@epita.fr>
 874
 875         * src/lalr.c (set_state_table): Move to...
 876         * src/LR0.c: here.
 877         * src/lalr.c (lalr): Don't call it...
 878         * src/LR0.c (generate_states): do it.
 879         * src/LR0.h (first_state): Remove, only the table is used.
 880
 881 2001-12-10  Akim Demaille  <akim@epita.fr>
 882
 883         * src/LR0.h (first_shift, first_reduction): Remove.
 884         * src/lalr.c: Don't use first_shift: find shifts through the
 885         states.
 886
 887 2001-12-10  Akim Demaille  <akim@epita.fr>
 888
 889         * src/LR0.c: Attach shifts to states as soon as they are
 890         computed.
 891         * src/lalr.c (set_state_table): Instead of assigning shifts to
 892         state, just assert that the mapping was properly done.
 893
 894 2001-12-10  Akim Demaille  <akim@epita.fr>
 895
 896         * src/LR0.c (insert_start_shift): Rename as...
 897         (insert_start_shifting_state): this.
 898         (insert_eof_shifting_state, insert_accepting_state): New.
 899         (augment_automaton): Adjust.
 900         Better locality of the variables.
 901         When looking if the start_symbol is shifted from the initial
 902         state, using `while (... symbol != start_symbol ...)' sounds
 903         better than `while (... symbol < start_symbol ...)': If fail
 904         to see how the order between symbols could be relevant!
 905
 906 2001-12-10  Akim Demaille  <akim@epita.fr>
 907
 908         * src/getargs.h: Don't declare `spec_name_prefix' and
 909         `spec_file_prefix', declared by src/files.h.
 910         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 911         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 912         * src/output.c (prepare): Adjust.
 913         * src/reader.c (symbols_output): Likewise.
 914         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 915
 916 2001-12-10  Akim Demaille  <akim@epita.fr>
 917
 918         * src/muscle_tab.c (muscle_init): NULL is a better default than
 919         `"0"'.
 920
 921 2001-12-10  Akim Demaille  <akim@epita.fr>
 922
 923         * src/reader.c (reader): Calling symbols_output once is enough.
 924
 925 2001-12-10  Akim Demaille  <akim@epita.fr>
 926
 927         Now that states have a complete set of members, the linked list of
 928         reductions is useless: just fill directly the state's reductions
 929         member.
 930
 931         * src/state.h (struct reductions): Remove member `number' and
 932         `next'.
 933         * src/LR0.c (first_reduction, last_reduction): Remove.
 934         (save_reductions): Don't link the new reductions, store them in
 935         this_state.
 936         * src/lalr.c (set_state_table): No need to attach reductions to
 937         states, it's already done.
 938         * src/output.c (output_actions): No longer free the shifts, then
 939         the reductions, then the states: free all the states and their
 940         members.
 941
 942 2001-12-10  Akim Demaille  <akim@epita.fr>
 943
 944         * src/options.c (OPTN, DRTV, BOTH): New.
 945         (option_table): Use them.
 946
 947         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 948         the job of system.h.
 949         * src/options.c: Don't include stdio.h and xalloc.h for the same
 950         reasons.
 951
 952 2001-12-10  Akim Demaille  <akim@epita.fr>
 953
 954         * src/output.c (output, prepare): Make sure the values of the
 955         muscles `action' and `prologue' are 0-terminated.
 956
 957 2001-12-10  Akim Demaille  <akim@epita.fr>
 958
 959         Clean up GCC warnings.
 960
 961         * src/reader.c (copy_action): `buf' is not used.
 962         (parse_skel_decl): Be static.
 963         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 964         * src/options.h (create_long_option_table): Have a real prototype.
 965         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 966         (hash_delete_at): Return const void *.
 967         Adjust casts to preserve the const.
 968
 969 2001-12-10  Akim Demaille  <akim@epita.fr>
 970
 971         * configure.in: Require 2.52g.
 972         M4 is not needed, but AUTOM4TE is.
 973         * m4/m4.m4: Remove.
 974         * tests/Makefile.am: Adjust.
 975
 976 2001-12-10  Akim Demaille  <akim@epita.fr>
 977
 978         One structure for states is enough, even though theoretically
 979         there are LR(0) states and LALR(1) states.
 980
 981         * src/lalr.h (state_t): Remove.
 982         (state_table): Be state_t **, not state_t *.
 983         * src/state.h (core, CORE_ALLOC): Rename as...
 984         (state_t, STATE_ALLOC): this.
 985         Add the LALR(1) members: shifts, reductions, errs.
 986         * src/LR0.c (state_table): Rename as...
 987         (state_hash): this, to avoid name clashes with the global
 988         `state_table'.
 989         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 990         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 991
 992 2001-12-10  Akim Demaille  <akim@epita.fr>
 993
 994         Bison dumps core on bash.y.
 995         Reported by Pascal Bart.
 996
 997         * src/warshall.c (bitmatrix_print): New.
 998         (TC): Use it.
 999         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1000         j must be the outer loop.
1001         * tests/regression.at (Broken Closure): New.
1002
1003 2001-12-05  Akim Demaille  <akim@epita.fr>
1004
1005         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1006         its argument.
1007         Reported by Peter Hámorský.
1008
1009 2001-12-05  Akim Demaille  <akim@epita.fr>
1010
1011         * src/conflicts.c (err_table): Remove.
1012         (resolve_sr_conflict): Adjust.
1013         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1014         Rename as...
1015         (state_t.reductions, state_t.shifts): this.
1016
1017 2001-12-05  Akim Demaille  <akim@epita.fr>
1018
1019         * src/reduce.c (reduce_grammar_tables): No longer disable the
1020         removal of useless rules via CPP but via `if (0)', so that the
1021         compiler still check the code is valid.
1022         For instance, it should have noticed `rline' no longer exists: use
1023         the `line' member of rule_t.
1024         * src/gram.c (dummy, rline): Remove, unused.
1025
1026 2001-12-05  Akim Demaille  <akim@epita.fr>
1027
1028         * src/output.c (pack_vector): Use assert, not berror.
1029         * src/main.c (berror): Remove, unused.
1030
1031 2001-12-05  Akim Demaille  <akim@epita.fr>
1032
1033         New experimental feature: if --verbose --trace output all the
1034         items of a state, not only its kernel.
1035
1036         * src/print.c (print_core): If `trace_flag', then invoke closure
1037         before outputting the items of the state (print_core is no longer
1038         a correct name them).
1039         (print_results): Invoke new_closure/free_closure if needed.
1040
1041 2001-12-05  Akim Demaille  <akim@epita.fr>
1042
1043         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1044         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1045         (nitemset): for consistency with the rest of the project.
1046
1047 2001-12-05  Akim Demaille  <akim@epita.fr>
1048
1049         * src/closure.c (print_closure): Improve.
1050         (closure): Use it for printing input and output.
1051
1052 2001-12-05  Akim Demaille  <akim@epita.fr>
1053
1054         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1055         indexed by nonterminals.
1056
1057 2001-12-05  Akim Demaille  <akim@epita.fr>
1058
1059         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1060         what it was!).
1061         * src/warshall.h: Remove accidental duplication of the content.
1062
1063 2001-12-05  Akim Demaille  <akim@epita.fr>
1064
1065         * src/closure.c (set_fderives): De-obfuscate.
1066
1067 2001-12-05  Akim Demaille  <akim@epita.fr>
1068
1069         * src/closure.c (print_firsts, print_fderives): De-obfuscate.

1071 2001-12-05  Akim Demaille  <akim@epita.fr>
1072
1073         * src/closure.c (set_firsts): De-obfuscate.
1074
1075 2001-12-05  Akim Demaille  <akim@epita.fr>
1076
1077         * src/output.c (action_row): De-obfuscate
1078         using the good o' techniques: arrays not pointers, variable
1079         locality, BITISSET, RESETBIT etc.
1080
1081 2001-12-05  Akim Demaille  <akim@epita.fr>
1082
1083         Pessimize the code to simplify it: from now on, all the states
1084         have a valid SHIFTS, which NSHIFTS is possibly 0.
1085
1086         * src/LR0.c (shifts_new): Be global and move to..
1087         * src/state.c, src/state.h: here.
1088         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1089         * src/print_graph: Adjust.
1090
1091 2001-12-05  Akim Demaille  <akim@epita.fr>
1092
1093         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1094         * src/conflicts.c: Use it.
1095         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1096         incorrectly ``simplified''.
1097
1098 2001-12-05  Akim Demaille  <akim@epita.fr>
1099
1100         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1101         using the good o' techniques: arrays not pointers, variable
1102         locality, BITISSET, RESETBIT etc.
1103

1105
1106         * src/state.h (SHIFT_SYMBOL): New.
1107         * src/conflicts.c: Use it to deobfuscate.
1108
1109 2001-12-05  Akim Demaille  <akim@epita.fr>
1110
1111         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1112         (print_reductions): De-obfuscate using the good o' techniques:
1113         arrays not pointers, variable locality, BITISSET.
1114
1115 2001-12-05  Akim Demaille  <akim@epita.fr>
1116
1117         * src/conflicts.c (print_reductions): Arrays, not pointers.
1118         Use BITISSET.

1137
1138         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

1140
1141 2001-12-05  Akim Demaille  <akim@epita.fr>
1142
1143         * src/LR0.c (augment_automaton): Formatting changes.
1144         Better variable locality.
1145
1146 2001-12-05  Akim Demaille  <akim@epita.fr>
1147
1148         * src/lalr.c (matrix_print): New.
1149         (transpose): Use it.
1150         Use arrays instead of pointers.
1151
1152 2001-12-05  Akim Demaille  <akim@epita.fr>
1153
1154         * src/lalr.c (maxrhs): Move to...
1155         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1156         * src/lalr.c (build_relations): Adjust.
1157
1158 2001-12-05  Akim Demaille  <akim@epita.fr>
1159
1160         * src/lalr.c (transpose): Free the memory allocated to the
1161         argument, as it is replaced by the results by the unique caller.
1162         (build_relations): Merely invoke transpose: it handles the memory
1163         deallocation.
1164         Improve variable locality.
1165         Avoid variables used as mere abbreviations.
1166         (compute_lookaheads): Use arrays instead of pointers.
1167
1168 2001-12-05  Akim Demaille  <akim@epita.fr>
1169
1170         * src/lalr.c (initialize_F): Improve variable locality.

1174
1175         * src/derives.c (print_derives): Display the ruleno.
1176         * src/lalr.c (initialize_F, transpose): Better variable locality
1177         to improve readability.
1178         Avoid variables used as mere abbreviations.
1179
1180 2001-12-05  Akim Demaille  <akim@epita.fr>
1181

1184 2001-12-05  Akim Demaille  <akim@epita.fr>
1185
1186         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1187         the handling of squeue.
1188         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1189
1190 2001-12-05  Akim Demaille  <akim@epita.fr>
1191
1192         Because useless nonterminals are now kept alive (instead of being
1193         `destroyed'), we now sometimes examine them, and store information
1194         related to them.  Hence we need to know their number, and adjust
1195         memory allocations.
1196
1197         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1198         static.
1199         * src/LR0.c (allocate_itemsets): The memory allocated to
1200         `symbol_count' was used for two different purpose: once to count
1201         the number of occurrences of each symbol, and later reassigned to
1202         `shift_symbol', containing the symbol that can be shifted from a
1203         given state.
1204         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1205         only, and...
1206         (new_itemsets): Allocate `shift_symbol' here.
1207         (allocate_itemsets): symbol_count includes useless nonterminals.
1208         Make room for them.
1209         (free_storage): Use `free', not `XFREE', for pointers that cannot
1210         be null.
1211
1212 2001-12-05  Akim Demaille  <akim@epita.fr>
1213
1214         * src/nullable.c (set_nullable): Deobfuscate the handling of
1215         ritem.
1216         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1217
1218 2001-12-05  Akim Demaille  <akim@epita.fr>
1219
1220         * src/gram.c, src/gram.h (ritem_print): New.
1221         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1222         (This useless function was defined only to work around VMS linkers
1223         that can't handle compilation units with variables only).
1224         * src/reduce.c (dump_grammar): Use it to trace the construction of
1225         ritem.
1226
1227 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1228
1229         * src/bison.simple (union yyalloc): Change member names
1230         to be the same as the stack names.
1231         (yyparse): yyptr is now union yyalloc *, not char *.
1232         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1233         and may generate better code on some machines.
1234         (yystpcpy): Use prototype if __STDC__ is defined, not just
1235         if __cplusplus is defined.
1236
1237 2001-11-30  Akim Demaille  <akim@epita.fr>
1238
1239         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1240         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1241         Gettext doesn't compile cleanly, and dies with -Werror.
1242         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1243         Include WARNING_CFLAGS here.
1244         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1245         before being defined.
1246
1247 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1248
1249         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1250         First arg is int, not unsigned.
1251         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1252         (SIZE_MAX, UINT_MAX): New macros.
1253         (quotearg_n_options): Abort if N is negative.
1254         Avoid overflow check on hosts where size_t is 64 bits and int
1255         is 32 bits, as overflow is impossible there.
1256         Fix off-by-one typo that caused unnecessary reallocation.
1257
1258 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1259
1260         Name space cleanup in generated parser.
1261
1262         * doc/bison.texinfo (Bison Parser): Discuss system headers
1263         and their effect on the user name space.
1264
1265         * src/bison.simple:
1266         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1267         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1268         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1269
1270         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1271         on user names when possible.
1272
1273         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1274         Simplify test for whather <alloca.h> exists.
1275
1276         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1277
1278         (<stdio.h>): Include if YYDEBUG.
1279
1280         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1281         ! defined (yyoverflow) && ! defined (yymemcpy).
1282
1283         (yymemcpy, yyparse): Rename local variables as needed so that
1284         they all begin with 'yy'.
1285
1286         (yystrlen, yystpcpy): New functions.
1287
1288         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1289         All uses changed.
1290
1291         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1292         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1293         and YYSTACK_FREE instead of malloc and free.
1294
1295 2001-11-30  Akim Demaille  <akim@epita.fr>
1296
1297         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1298         before their first uses.
1299         (YYBISON, YYPURE): Move to the top of the output.

1304
1305 2001-11-30  Akim Demaille  <akim@epita.fr>
1306
1307         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1308         if body instead of `;' to pacify GCC's warnings.
1309
1310 2001-11-30  Akim Demaille  <akim@epita.fr>
1311
1312         Instead of mapping the LHS of unused rules to -1, keep the LHS
1313         valid, but flag the rules as invalid.
1314
1315         * src/gram.h (rule_t): `useful' is a new member.
1316         * src/print.c (print_grammar): Adjust.

1319         * src/reduce.c (reduce_grammar_tables): Likewise.
1320         * tests/reduce.at (Underivable Rules, Useless Rules): New.

1328
1329 2001-11-30  Akim Demaille  <akim@epita.fr>
1330
1331         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1332         useless nonterminals, move them at the end of the symbol arrays.
1333         (reduce_output): Adjust.
1334         * tests/reduce.at (Useless Nonterminals): Adjust.
1335
1336 2001-11-30  Akim Demaille  <akim@epita.fr>
1337

1339         (nonterminals_reduce): New, extracted from...
1340         (reduce_grammar_tables): here.
1341         (reduce_grammar): Call nonterminals_reduce.
1342
1343 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1344
1345         * src/bison.simple (YYSTACK_REALLOC): Remove.
1346         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1347         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1348         New macros.
1349         (union yyalloc): New type.
1350         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1351         an arbitrary restriction on hosts where size_t is wider than int.
1352
1353         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1354         a parser stack overflow.  Allocate just one block of memory for all
1355         three stacks, instead of allocating three blocks; this typically is
1356         faster and reduces fragmentation.
1357
1358         Do not limit the number of items in the stack to a value that fits
1359         in 'int', as this is an arbitrary limit on hosts with 64-bit
1360         size_t and 32-bit int.
1361
1362 2001-11-29  Marc Autret  <autret_m@epita.fr>
1363
1364         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
1365         of defining YYERROR_VERBOSE.

1368 2001-11-28  Marc Autret  <autret_m@epita.fr>

1378         * src/output.c (error_verbose): Define here.
1379         (prepare): Echo name modification.
1380         * src/getargs.h: Clean its extern declaration.
1381         * src/getargs.c (error_verbose_flag): Remove.
1382         (getargs): Remove case 'e'.
1383         * src/options.c (option_table): 'error-verbose' is now seen as simple
1384         percent option.
1385         Include output.h.
1386
1387         * src/reader.c (read_declarations): Remove case tok_include.
1388         (parse_include_decl): Remove.

1390         * src/options.c (option_table): 'include' is now a simple command line
1391         option.
1392
1393 2001-11-28  Marc Autret  <autret_m@epita.fr>
1394
1395         * src/bison.simple: Adjust muscle names.
1396         * src/muscle_tab.c (muscle_init): Also rename the muscles.

1398         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
1399
1400 2001-11-28  Marc Autret  <autret_m@epita.fr>

1409
1410 2001-11-28  Akim Demaille  <akim@epita.fr>
1411
1412         * src/closure.c (closure): `b' and `ruleno' denote the same value:
1413         keep ruleno only.
1414
1415 2001-11-28  Akim Demaille  <akim@epita.fr>
1416
1417         * src/closure.c (closure): Instead of looping over word in array
1418         then bits in words, loop over bits in array.
1419
1420 2001-11-28  Akim Demaille  <akim@epita.fr>
1421
1422         * src/closure.c (closure): No longer optimize the special case
1423         where all the bits of `ruleset[r]' are set to 0, to make the code
1424         clearer.
1425
1426 2001-11-28  Akim Demaille  <akim@epita.fr>
1427
1428         * src/closure.c (closure): `r' and `c' are new variables, used to
1429         de-obfuscate accesses to RULESET and CORE.

1442         * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
1443         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
1444         as all tags are free'ed afterwards.
1445         From Enrico Scholz.
1446
1447 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1448
1449         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
1450         use alloca when we didn't want to, and vice versa.
1451
1452 2001-11-27  Marc Autret  <autret_m@epita.fr>

2827         with something new. Skeletons are now processed character by character

3176         import in Bison features implemented in 2.49c since 2.13.

3212         * src/lex.c (percent_table): Also accept `%yacc',
3213         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3214         `%debug'.
3215         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3216         instead of returning a token.
3217         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3218         * src/reader.c (read_declarations): Adjust.
3219         * src/files.c (open_files): Don't call `compute_base_names', don't

3221         *in* the input file now.
3222         (output_files): Do it here.
3223         * src/output.c (output_headers): Document the fact that this patch

3252

3288         * tests/suite.at (Checking output file names): New test.

3360         * lib/obstack.h: Formatting changes.
3361         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3362         prevents type checking.
3363         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3364         cast the value to (void *): assigning a `foo *' to a `void *'

3447         * src/main.c (main): Don't use `atexit' to register `done', since
3448         it no longer has to remove tmp files, just call `output_files'
3449         when there are no errors.
3450

3554         When a literal string is used to define two different tokens,
3555         `bison -v' segfaults.
3556         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3557
3558         * tests/regression.m4: New file.
3559         Include the core of the sample provided by Piotr Gackiewicz.

3570
3571         * bison.s1 (yyparse): Assign the default value
3572         unconditionally, to avoid a GCC warning and make the parser a
3573         tad smaller.

3586
3587         The location tracking mechanism is precious for parse error
3588         messages.  Nevertheless, it is enabled only when `@n' is used in
3589         the grammar, which is a different issue (you can use it in error
3590         message, but not in the grammar per se).  Therefore, there should
3591         be another means to enable it.
3592
3593         * src/getargs.c (getargs): Support `--locations'.
3594         (usage): Report it.

3596         * src/lex.c (percent_table): Support `%locations'.
3597         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3598         with `locationsflag'.
3599         * doc/bison.texinfo: Document `--locations' and `%locations'.
3600         Sort the options.
3601         * tests/calc.m4: Test it.
3602
3603         For regularity of the names, replace each
3604         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3605         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3606         In addition replace each `flag' with `_flag'.
3607
3608 2000-10-02  Akim Demaille  <akim@epita.fr>
3609
3610         Also test parse error messages, including with YYERROR_VERBOSE.
3611
3612         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3613         associative).
3614         Use it to check the computations.
3615         Use it to check `nonassoc' is honored.
3616         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3617         `--yyerror-verbose'.
3618         (_AT_CHECK_CALC): Adjust to this option.

3620
3621 2000-10-02  Akim Demaille  <akim@epita.fr>
3622
3623         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3624         the latter demonstrates a flaw in the handling of non debugging
3625         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3626         was used in order to simplify:
3627
3628         #if YYDEBUG
3629         if (yydebug)
3630         {
3631         ...
3632         }
3633         #endif
3634
3635         into
3636
3637         if (yydebug)
3638         {
3639         ...
3640         }
3641
3642         unfortunately this leads to a CPP conflict when
3643         `--name-prefix=foo' is used since it produces `#define yydebug
3644         foodebug'.
3645
3646         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3647         (YYDPRINTF): New macro.
3648         Spread its use.
3649         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3650         the bison options.
3651         Also test `--verbose', `--defines' and `--name-prefix'.
3652

3654
3655         Improve the readability of the produced parsers.
3656
3657         * src/bison.s1: Formatting changes.
3658         Improve the comment related to the `$' mark.
3659         (yydefault): Don't fall through to `yyresume': `goto' there.
3660         * src/output.c (output_parser): When the `$' is met, skip the end
3661         of its line.
3662         New variable, `number_of_dollar_signs', to check there's exactly
3663         one `$' in the parser skeleton.
3664
3665 2000-10-02  Akim Demaille  <akim@epita.fr>
3666
3667         * lib/xstrdup.c: New file, from the fileutils.
3668         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3669         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3670         instead of strlen + xmalloc + strcpy.
3671         * src/symtab.c (copys): Remove, use xstrdup instead.
3672
3673 2000-10-02  Akim Demaille  <akim@epita.fr>
3674
3675         * src/gram.h (associativity): New enum type which replaces the
3676         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3677         `right_assoc', `left_assoc' and `non_assoc'.
3678         Adjust all dependencies.
3679         * src/reader.c: Formatting changes.
3680         (LTYPESTR): Don't define it, use it as a literal in
3681         `reader_output_yylsp'.
3682         * src/symtab.h (symbol_class): New enum type which replaces the
3683         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3684         `sunknown', `stoken and `snterm'.
3685
3686 2000-10-02  Akim Demaille  <akim@epita.fr>
3687
3688         * src/getargs.c (fixed_outfiles): Rename as...
3689         (yaccflag): for consistency and accuracy.
3690         Adjust dependencies.
3691
3692 2000-10-02  Akim Demaille  <akim@epita.fr>
3693
3694         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3695         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3696         difficult and introduced a lot of core dump.  It turns out that
3697         Bison used an implementation of `xmalloc' based on `calloc', and
3698         at various places it does depend upon the initialization to 0.  I
3699         have not tried to isolate the pertinent places, and all the former
3700         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3701         someone should address this issue.
3702
3703         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3704         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
3705         files.
3706         Adjust dependencies.
3707         * src/warshall.h: New file.
3708         Propagate.

3710 2000-10-02  Akim Demaille  <akim@epita.fr>
3711
3712         Various anti-`extern in *.c' changes.
3713
3714         * src/system.h: Include `assert.h'.
3715
3716 2000-10-02  Akim Demaille  <akim@epita.fr>
3717
3718         * src/state.h (nstates, final_state, first_state, first_shift)
3719         (first_reduction): Move their exportation from here...
3720         * src/LR0.h: to here.

3796 2000-10-02  Akim Demaille  <akim@epita.fr>
3797
3798         * src/output.c (token_actions): Introduce a temporary array,
3799         YYDEFACT, that makes it possible for this function to use

3801
3802 2000-10-02  Akim Demaille  <akim@epita.fr>
3803
3804         `user_toknums' is output as a `short[]' in `output.c', while it is
3805         defined as a `int[]' in `reader.c'.  For consistency with the
3806         other output tables, `user_toknums' is now defined as a table of
3807         shorts.
3808
3809         * src/reader.c (user_toknums): Be a short table instead of an int
3810         table.

3822         order to get rid of the `static' prototypes.
3823         No longer use `register'.
3824         * src/output.h: New file.
3825         Propagate its inclusion in files explicitly prototyping functions
3826         from output.c.

3835         * src/closure.c: Formatting changes, topological sort over the
3836         functions, use of closure.h.
3837         (initialize_closure, finalize_closure):  Rename as...

3848         inclusion.
3849         Don't define PARAMS.
3850         * src/system.h: Define PARAMS.
3851         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3852         purpose of config.h.  system.h must not try to fix wrong
3853         definitions in config.h.

4016
4017 2000-03-17  Akim Demaille  <akim@epita.fr>
4018

4041         copy_comment.  Removed now unused `match', `ended',
4042         `cplus_comment'.
4043         (copy_comment, copy_string): Moved, to be visible from

4070
4071         Change the handling of @s so that they behave exactly like $s.
4072         There is now a pseudo variable @$ (readble and writable), location
4073         of the lhs of the rule (by default ranging from the location of
4074         the first symbol of the rhs, to the location of the last symbol,
4075         or, if the rhs is empty, YYLLOC).
4076

4078         yyval.
4079         (yyparse): When providing a default semantic action, provide a
4080         default location action.
4081         (after the $): No longer change `*YYLSP', just stack YYLOC the
4082         same way you stack YYVAL.
4083         * src/reader.c (read_declarations): Use warns.
4084         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4085         (copy_action, case '@'): Likewise.
4086         Use a standard error message, to save useless work from
4087         translators.

4108
4109         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4110         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4111         One `#if YYDEBUG' remains, since it uses variables which are
4112         defined only if `YYDEBUG != 0'.
4113
4114 2000-03-16  Akim Demaille  <akim@epita.fr>

4138         handled via src/Makefile.am.

4140         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
4141         autoheader.

4146         the proper line number and file name.
4147         (DEFS): Propagate the location of bison library files and of the
4148         locale files.
4149         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4150         builddir.
4151         * acinclude.m4: Remove, replaced by the directory m4.
4152         * m4/Makefile.am (EXTRA_DIST): New variable.
4153         * m4/gettext.m4: New file, from the fileutils.

4799         (get_type, packsymbols):  Revised most error messages.
4800         Changed `fatal' to `warnxxx' to avoid aborting for error.
4801         Revised and use multiple warnxxx functions to avoid using VARARGS1.
4802         (read_declarations): Improve the error message for

4818          If reader sees an error, don't process the grammar.
4819         (fatals): Updated to not use VARARGS1.
4820         (printable_version, int_to_string, warn, warni, warns, warnss)
4821         (warnsss): New error reporting functions.  Avoid abort for error.
4822

4833         (literalchar, lex, parse_percent_token): Made tokenbuffer
4834         always contain the token.  This includes growing the token
4835         buffer while reading an integer.

4837         (parse_percent_token): Added % declarations as another
4838         way to specify the flags -n, -l, and -r.  Also added hooks for
4839         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4840         major changes to files.c.
4841         (lex) Retain in the incoming stream a character following
4842         an incorrect '/'.
4843         (skip_white_space, lex):  Revised most error messages
4844         and changed fatal to warn to avoid aborting.
