ChangeLog

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

 730         * src/options.c (OPTN, DRTV, BOTH): New.
 731         (option_table): Use them.
 732
 733         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 734         the job of system.h.
 735         * src/options.c: Don't include stdio.h and xalloc.h for the same
 736         reasons.
 737
 738 2001-12-10  Akim Demaille  <akim@epita.fr>
 739
 740         * src/output.c (output, prepare): Make sure the values of the
 741         muscles `action' and `prologue' are 0-terminated.
 742
 743 2001-12-10  Akim Demaille  <akim@epita.fr>
 744
 745         Clean up GCC warnings.
 746
 747         * src/reader.c (copy_action): `buf' is not used.
 748         (parse_skel_decl): Be static.
 749         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 750         * src/options.h (create_long_option_table): Have a real prototype.
 751         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 752         (hash_delete_at): Return const void *.
 753         Adjust casts to preserve the const.
 754
 755 2001-12-10  Akim Demaille  <akim@epita.fr>
 756
 757         * configure.in: Require 2.52g.
 758         M4 is not needed, but AUTOM4TE is.
 759         * m4/m4.m4: Remove.
 760         * tests/Makefile.am: Adjust.
 761
 762 2001-12-10  Akim Demaille  <akim@epita.fr>
 763
 764         One structure for states is enough, even though theoretically
 765         there are LR(0) states and LALR(1) states.
 766
 767         * src/lalr.h (state_t): Remove.
 768         (state_table): Be state_t **, not state_t *.
 769         * src/state.h (core, CORE_ALLOC): Rename as...
 770         (state_t, STATE_ALLOC): this.
 771         Add the LALR(1) members: shifts, reductions, errs.
 772         * src/LR0.c (state_table): Rename as...
 773         (state_hash): this, to avoid name clashes with the global
 774         `state_table'.
 775         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 776         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 777
 778 2001-12-10  Akim Demaille  <akim@epita.fr>
 779
 780         Bison dumps core on bash.y.
 781         Reported by Pascal Bart.
 782
 783         * src/warshall.c (bitmatrix_print): New.
 784         (TC): Use it.
 785         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 786         j must be the outer loop.
 787         * tests/regression.at (Broken Closure): New.
 788
 789 2001-12-05  Akim Demaille  <akim@epita.fr>
 790
 791         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 792         its argument.
 793         Reported by Peter Hámorský.
 794
 795 2001-12-05  Akim Demaille  <akim@epita.fr>
 796
 797         * src/conflicts.c (err_table): Remove.
 798         (resolve_sr_conflict): Adjust.
 799         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 800         Rename as...
 801         (state_t.reductions, state_t.shifts): this.
 802
 803 2001-12-05  Akim Demaille  <akim@epita.fr>
 804
 805         * src/reduce.c (reduce_grammar_tables): No longer disable the
 806         removal of useless rules via CPP but via `if (0)', so that the
 807         compiler still check the code is valid.
 808         For instance, it should have noticed `rline' no longer exists: use
 809         the `line' member of rule_t.
 810         * src/gram.c (dummy, rline): Remove, unused.
 811
 812 2001-12-05  Akim Demaille  <akim@epita.fr>
 813
 814         * src/output.c (pack_vector): Use assert, not berror.
 815         * src/main.c (berror): Remove, unused.
 816
 817 2001-12-05  Akim Demaille  <akim@epita.fr>
 818
 819         New experimental feature: if --verbose --trace output all the
 820         items of a state, not only its kernel.
 821
 822         * src/print.c (print_core): If `trace_flag', then invoke closure
 823         before outputting the items of the state (print_core is no longer
 824         a correct name them).
 825         (print_results): Invoke new_closure/free_closure if needed.
 826
 827 2001-12-05  Akim Demaille  <akim@epita.fr>
 828
 829         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 830         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 831         (nitemset): for consistency with the rest of the project.
 832
 833 2001-12-05  Akim Demaille  <akim@epita.fr>
 834
 835         * src/closure.c (print_closure): Improve.
 836         (closure): Use it for printing input and output.
 837
 838 2001-12-05  Akim Demaille  <akim@epita.fr>
 839
 840         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 841         indexed by nonterminals.
 842
 843 2001-12-05  Akim Demaille  <akim@epita.fr>
 844
 845         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 846         what it was!).
 847         * src/warshall.h: Remove accidental duplication of the content.
 848
 849 2001-12-05  Akim Demaille  <akim@epita.fr>
 850
 851         * src/closure.c (set_fderives): De-obfuscate.
 852
 853 2001-12-05  Akim Demaille  <akim@epita.fr>
 854
 855         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
 856
 857 2001-12-05  Akim Demaille  <akim@epita.fr>
 858
 859         * src/closure.c (set_firsts): De-obfuscate.
 860
 861 2001-12-05  Akim Demaille  <akim@epita.fr>
 862
 863         * src/output.c (action_row): De-obfuscate
 864         using the good o' techniques: arrays not pointers, variable
 865         locality, BITISSET, RESETBIT etc.
 866
 867 2001-12-05  Akim Demaille  <akim@epita.fr>
 868
 869         Pessimize the code to simplify it: from now on, all the states
 870         have a valid SHIFTS, which NSHIFTS is possibly 0.
 871
 872         * src/LR0.c (shifts_new): Be global and move to..
 873         * src/state.c, src/state.h: here.
 874         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 875         * src/print_graph: Adjust.
 876
 877 2001-12-05  Akim Demaille  <akim@epita.fr>
 878
 879         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 880         * src/conflicts.c: Use it.
 881         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 882         incorrectly ``simplified''.
 883
 884 2001-12-05  Akim Demaille  <akim@epita.fr>
 885
 886         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
 887         using the good o' techniques: arrays not pointers, variable
 888         locality, BITISSET, RESETBIT etc.
 889
 890 2001-12-05  Akim Demaille  <akim@epita.fr>
 891
 892         * src/state.h (SHIFT_SYMBOL): New.
 893         * src/conflicts.c: Use it to deobfuscate.
 894
 895 2001-12-05  Akim Demaille  <akim@epita.fr>
 896
 897         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
 898         (print_reductions): De-obfuscate using the good o' techniques:
 899         arrays not pointers, variable locality, BITISSET.
 900
 901 2001-12-05  Akim Demaille  <akim@epita.fr>
 902
 903         * src/conflicts.c (print_reductions): Arrays, not pointers.
 904         Use BITISSET.
 905
 906 2001-12-05  Akim Demaille  <akim@epita.fr>
 907
 908         * src/conflicts.c (print_reductions): Pessimize, but clarify.
 909
 910 2001-12-05  Akim Demaille  <akim@epita.fr>
 911
 912         * src/conflicts.c (print_reductions): Improve variable locality.
 913
 914 2001-12-05  Akim Demaille  <akim@epita.fr>
 915
 916         * src/conflicts.c (print_reductions): Pessimize, but clarify.
 917
 918 2001-12-05  Akim Demaille  <akim@epita.fr>
 919
 920         * src/conflicts.c (print_reductions): Improve variable locality.
 921
 922 2001-12-05  Akim Demaille  <akim@epita.fr>
 923
 924         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
 925         * src/lalr.c: Use them.
 926
 927 2001-12-05  Akim Demaille  <akim@epita.fr>
 928
 929         * src/LR0.c (augment_automaton): Formatting changes.
 930         Better variable locality.
 931
 932 2001-12-05  Akim Demaille  <akim@epita.fr>
 933
 934         * src/lalr.c (matrix_print): New.
 935         (transpose): Use it.
 936         Use arrays instead of pointers.
 937
 938 2001-12-05  Akim Demaille  <akim@epita.fr>
 939
 940         * src/lalr.c (maxrhs): Move to...
 941         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
 942         * src/lalr.c (build_relations): Adjust.
 943
 944 2001-12-05  Akim Demaille  <akim@epita.fr>
 945
 946         * src/lalr.c (transpose): Free the memory allocated to the
 947         argument, as it is replaced by the results by the unique caller.
 948         (build_relations): Merely invoke transpose: it handles the memory
 949         deallocation.
 950         Improve variable locality.
 951         Avoid variables used as mere abbreviations.
 952         (compute_lookaheads): Use arrays instead of pointers.
 953
 954 2001-12-05  Akim Demaille  <akim@epita.fr>
 955
 956         * src/lalr.c (initialize_F): Improve variable locality.
 957         Avoid variables used as mere abbreviations.
 958
 959 2001-12-05  Akim Demaille  <akim@epita.fr>
 960
 961         * src/derives.c (print_derives): Display the ruleno.
 962         * src/lalr.c (initialize_F, transpose): Better variable locality
 963         to improve readability.
 964         Avoid variables used as mere abbreviations.
 965
 966 2001-12-05  Akim Demaille  <akim@epita.fr>
 967
 968         * src/lalr.c (traverse): Use arrays instead of pointers.
 969
 970 2001-12-05  Akim Demaille  <akim@epita.fr>
 971
 972         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
 973         the handling of squeue.
 974         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 975
 976 2001-12-05  Akim Demaille  <akim@epita.fr>
 977
 978         Because useless nonterminals are now kept alive (instead of being
 979         `destroyed'), we now sometimes examine them, and store information
 980         related to them.  Hence we need to know their number, and adjust
 981         memory allocations.
 982
 983         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
 984         static.
 985         * src/LR0.c (allocate_itemsets): The memory allocated to
 986         `symbol_count' was used for two different purpose: once to count
 987         the number of occurrences of each symbol, and later reassigned to
 988         `shift_symbol', containing the symbol that can be shifted from a
 989         given state.
 990         Deobfuscate, i.e., allocate, use and free `symbol_count' here
 991         only, and...
 992         (new_itemsets): Allocate `shift_symbol' here.
 993         (allocate_itemsets): symbol_count includes useless nonterminals.
 994         Make room for them.
 995         (free_storage): Use `free', not `XFREE', for pointers that cannot
 996         be null.
 997
 998 2001-12-05  Akim Demaille  <akim@epita.fr>
 999
1000         * src/nullable.c (set_nullable): Deobfuscate the handling of
1001         ritem.
1002         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1003
1004 2001-12-05  Akim Demaille  <akim@epita.fr>
1005
1006         * src/gram.c, src/gram.h (ritem_print): New.
1007         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1008         (This useless function was defined only to work around VMS linkers
1009         that can't handle compilation units with variables only).
1010         * src/reduce.c (dump_grammar): Use it to trace the construction of
1011         ritem.
1012
1013 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1014
1015         * src/bison.simple (union yyalloc): Change member names
1016         to be the same as the stack names.
1017         (yyparse): yyptr is now union yyalloc *, not char *.
1018         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1019         and may generate better code on some machines.
1020         (yystpcpy): Use prototype if __STDC__ is defined, not just
1021         if __cplusplus is defined.
1022
1023 2001-11-30  Akim Demaille  <akim@epita.fr>
1024
1025         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1026         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1027         Gettext doesn't compile cleanly, and dies with -Werror.
1028         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1029         Include WARNING_CFLAGS here.
1030         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1031         before being defined.
1032
1033 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1034
1035         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1036         First arg is int, not unsigned.
1037         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1038         (SIZE_MAX, UINT_MAX): New macros.
1039         (quotearg_n_options): Abort if N is negative.
1040         Avoid overflow check on hosts where size_t is 64 bits and int
1041         is 32 bits, as overflow is impossible there.
1042         Fix off-by-one typo that caused unnecessary reallocation.
1043
1044 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1045
1046         Name space cleanup in generated parser.
1047
1048         * doc/bison.texinfo (Bison Parser): Discuss system headers
1049         and their effect on the user name space.
1050
1051         * src/bison.simple:
1052         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1053         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1054         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1055
1056         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1057         on user names when possible.
1058
1059         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1060         Simplify test for whather <alloca.h> exists.
1061
1062         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1063
1064         (<stdio.h>): Include if YYDEBUG.
1065
1066         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1067         ! defined (yyoverflow) && ! defined (yymemcpy).
1068
1069         (yymemcpy, yyparse): Rename local variables as needed so that
1070         they all begin with 'yy'.
1071
1072         (yystrlen, yystpcpy): New functions.
1073
1074         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1075         All uses changed.
1076
1077         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1078         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1079         and YYSTACK_FREE instead of malloc and free.
1080
1081 2001-11-30  Akim Demaille  <akim@epita.fr>
1082
1083         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1084         before their first uses.
1085         (YYBISON, YYPURE): Move to the top of the output.
1086
1087 2001-11-30  Akim Demaille  <akim@epita.fr>
1088
1089         * tests/reduce.at (Useless Nonterminals): Fix.
1090
1091 2001-11-30  Akim Demaille  <akim@epita.fr>
1092
1093         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1094         if body instead of `;' to pacify GCC's warnings.
1095
1096 2001-11-30  Akim Demaille  <akim@epita.fr>
1097
1098         Instead of mapping the LHS of unused rules to -1, keep the LHS

1116

1136         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1137         an arbitrary restriction on hosts where size_t is wider than int.
1138
1139         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1140         a parser stack overflow.  Allocate just one block of memory for all
1141         three stacks, instead of allocating three blocks; this typically is
1142         faster and reduces fragmentation.
1143
1144         Do not limit the number of items in the stack to a value that fits
1145         in 'int', as this is an arbitrary limit on hosts with 64-bit
1146         size_t and 32-bit int.

1208         * src/closure.c (closure): No longer optimize the special case

2525
2526         * src/bison.simple (yyparse): Don't take the address of an
2527         item before the start of an array, as that doesn't conform to
2528         the C Standard.

2536         completely wrong.

2573         string delimiters or not.
2574         (copy_string): Be a simple call to copy_string2 with the last argument
2575         bound to true.
2576         (read_declarations): Add case for macro definition.
2577         (copy_identifier): New.
2578         (parse_macro_decl): Read macro identifiers using copy_identifier
2579         rather than lex.

2598         table with a macro. No output to the table obstack.
2599         (output_gram): Same for 'rhs' and 'prhs'.
2600         (output_stos): Same for 'stos'.

2611
2612         * src/output.c (output_parser): Replace most of the skeleton copy code
2613         with something new. Skeletons are now processed character by character
2614         rather than line by line, and Bison looks for '%%' macros. This is the
2615         first step in making Bison's output process (a lot) more flexible.
2616         (output_parser): Use the macro table.

2916
2917         * config/: New.

2942
2943 2001-02-21  Akim Demaille  <akim@epita.fr>
2944
2945         * src/reader.c (gensym): `gensym_count' is your own.
2946         Use a static buf to create the symbol name, as token_buffer is no
2947         longer a buffer.
2948
2949 2001-02-08  Akim Demaille  <akim@epita.fr>
2950
2951         * src/conflicts.c (conflict_report): Be sure not to append to res
2952         between two calls, which could happen if both first sprintf were
2953         skipped, but not the first cp += strlen.
2954
2955 2001-02-08  Akim Demaille  <akim@epita.fr>
2956
2957         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
2958         New, from fileutils 4.0.37.
2959         * configure.in: Require Autoconf 2.49c.  I took some time before
2960         making this decision.  This is the only way out for portability
2961         issues in Bison, it would mean way too much duplicate effort to
2962         import in Bison features implemented in 2.49c since 2.13.
2963         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
2964
2965 2001-02-02  Akim Demaille  <akim@epita.fr>

2971
2972         Get rid of the ad hoc handling of token_buffer in the scanner: use
2973         the obstacks.
2974
2975         * src/lex.c (token_obstack): New.
2976         (init_lex): Initialize it.  No longer call...

2978         Adjust all the places which used it to use the obstack.
2979
2980 2001-01-19  Akim Demaille  <akim@epita.fr>
2981
2982         * src/lex.h: Rename all the tokens:
2983         s/\bENDFILE\b/tok_eof/g;
2984         s/\bIDENTIFIER\b/tok_identifier/g;
2985         etc.
2986         Let them be enums, not #define, to ease debugging.
2987         Adjust all the code.
2988
2989 2001-01-18  Akim Demaille  <akim@epita.fr>
2990
2991         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
2992         * src/lex.c (maxtoken, grow_token_buffer): Static.
2993
2994 2001-01-18  Akim Demaille  <akim@epita.fr>
2995
2996         Since we now use obstacks, more % directives can be enabled.
2997
2998         * src/lex.c (percent_table): Also accept `%yacc',
2999         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3000         `%debug'.
3001         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3002         instead of returning a token.
3003         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3004         * src/reader.c (read_declarations): Adjust.
3005         * src/files.c (open_files): Don't call `compute_base_names', don't
3006         compute `attrsfile' since they depend upon data which might be
3007         *in* the input file now.
3008         (output_files): Do it here.
3009         * src/output.c (output_headers): Document the fact that this patch
3010         introduces a guaranteed SEGV for semantic parsers.
3011         * doc/bison.texinfo: Document them.
3012         * tests/suite.at: Exercise these %options.
3013
3014 2000-12-20  Akim Demaille  <akim@epita.fr>
3015
3016         Also handle the output file (--verbose) with obstacks.
3017
3018         * files.c (foutput): Remove.
3019         (output_obstack): New.

3022         * src/system.h (obstack_grow_string): Rename as...
3023         (obstack_sgrow): this.  Be ready to work with non literals.

3028         * src/files.c (open_files): Fix the computation of short_base_name
3029         in the case of `-o foo.tab.c'.
3030
3031 2000-12-20  Akim Demaille  <akim@epita.fr>
3032
3033         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3034         (copy_dollar): Now that everything uses obstacks, get rid of the
3035         FILE * parameters.
3036
3037 2000-12-20  Akim Demaille  <akim@epita.fr>
3038
3039         * src/files.c (open_files): Actually the `.output' file is based
3040         on the short_base_name, not base_name.
3041         * tests/suite.at (Checking output file names): Adjust.
3042
3043 2000-12-20  Akim Demaille  <akim@epita.fr>
3044
3045         * src/bison.s1: Remove, we now use directly...
3046         * src/bison.simple: this.
3047         * src/Makefile.am: Use pkgdata instead of data.
3048

3062         (output_files): Adjust.
3063         (base_name, short_base_name): Be global.
3064         Adjust dependencies.
3065
3066 2000-12-19  Akim Demaille  <akim@epita.fr>
3067
3068         * src/files.c (strsuffix): New.
3069         (stringappend): Be just like strcat but allocate.
3070         (base_names): Eve out from open_files.
3071         Try to simplify the rather hairy computation of base_name and
3072         short_base_name.
3073         (open_files): Use it.
3074         * tests/suite.at (Checking output file names): New test.

3084
3085 2000-12-19  Akim Demaille  <akim@epita.fr>
3086
3087         * src/output.c (output_parser): Compute the `#line' lines when
3088         there are.
3089         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

3091
3092 2000-12-19  Akim Demaille  <akim@epita.fr>
3093
3094         Let the handling of the skeleton files be local to the procedures
3095         that use it.
3096
3097         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

3113

3115         looking for `/tmp' since we have no tmp file.
3116
3117 2000-12-19  Akim Demaille  <akim@epita.fr>
3118
3119         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3146         * lib/obstack.h: Formatting changes.
3147         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3148         prevents type checking.
3149         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3150         cast the value to (void *): assigning a `foo *' to a `void *'
3151         variable is valid.

3188
3189 2000-11-07  Akim Demaille  <akim@epita.fr>
3190
3191         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

3196         * src/output.c (output): Remove useless variables.
3197         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3198         argument `data' for consistency with the prototypes.
3199         Qualify it `const'.
3200         (obstack_copy, obstack_copy0): Rename the second argument as
3201         `address' for consistency.  Qualify it `const'.

3213 2000-11-03  Akim Demaille  <akim@epita.fr>
3214
3215         For some reason, this was not applied.
3216
3217         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3231         (output_files): this.
3232         Use `obstack_save'.
3233         * src/main.c (main): Don't use `atexit' to register `done', since
3234         it no longer has to remove tmp files, just call `output_files'
3235         when there are no errors.
3236
3237 2000-11-02  Akim Demaille  <akim@epita.fr>
3238
3239         * src/files.c [VMS]: No longer include `ssdef.h', no longer define
3240         `unlink': it's no longer used.

3242
3243 2000-11-02  Akim Demaille  <akim@epita.fr>

3307         the `/' which is suspected to open a comment, instead of being
3308         called after `//' or `/*' was read.
3309         (copy_comment, copy_definition, parse_union_decl, copy_action)
3310         (copy_guard): Adjust.

3337
3338 2000-10-04  Akim Demaille  <akim@epita.fr>
3339
3340         When a literal string is used to define two different tokens,
3341         `bison -v' segfaults.
3342         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3343
3344         * tests/regression.m4: New file.
3345         Include the core of the sample provided by Piotr Gackiewicz.
3346         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3347         properly.
3348
3349 2000-10-04  Akim Demaille  <akim@epita.fr>
3350
3351         * src/reader.c (parse_expect_decl): Keep `count' within the size
3352         of `buffer'.
3353         From Neil Booth.
3354
3355 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3356
3357         * bison.s1 (yyparse): Assign the default value
3358         unconditionally, to avoid a GCC warning and make the parser a
3359         tad smaller.
3360
3361 2000-10-02  Akim Demaille  <akim@epita.fr>
3362
3363         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3364         options.
3365
3366 2000-10-02  Akim Demaille  <akim@epita.fr>
3367
3368         * src/derives.c, src/print.c, src/reduce.c: To ease the
3369         translation, move some `\n' out of the translated strings.
3370
3371 2000-10-02  Akim Demaille  <akim@epita.fr>
3372
3373         The location tracking mechanism is precious for parse error
3374         messages.  Nevertheless, it is enabled only when `@n' is used in
3375         the grammar, which is a different issue (you can use it in error
3376         message, but not in the grammar per se).  Therefore, there should
3377         be another means to enable it.
3378
3379         * src/getargs.c (getargs): Support `--locations'.
3380         (usage): Report it.
3381         * src/getargs.h (locationsflag): Export it.
3382         * src/lex.c (percent_table): Support `%locations'.
3383         * src/reader.c (yylsp_needed): Remove this variable, now replaced
3384         with `locationsflag'.
3385         * doc/bison.texinfo: Document `--locations' and `%locations'.
3386         Sort the options.
3387         * tests/calc.m4: Test it.
3388
3389         For regularity of the names, replace each
3390         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3391         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3392         In addition replace each `flag' with `_flag'.
3393
3394 2000-10-02  Akim Demaille  <akim@epita.fr>
3395
3396         Also test parse error messages, including with YYERROR_VERBOSE.
3397
3398         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3399         associative).
3400         Use it to check the computations.
3401         Use it to check `nonassoc' is honored.
3402         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3403         `--yyerror-verbose'.
3404         (_AT_CHECK_CALC): Adjust to this option.
3405         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3406
3407 2000-10-02  Akim Demaille  <akim@epita.fr>
3408
3409         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3410         the latter demonstrates a flaw in the handling of non debugging
3411         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3412         was used in order to simplify:
3413
3414         #if YYDEBUG
3415         if (yydebug)
3416         {
3417         ...
3418         }
3419         #endif
3420
3421         into
3422
3423         if (yydebug)
3424         {
3425         ...
3426         }
3427
3428         unfortunately this leads to a CPP conflict when
3429         `--name-prefix=foo' is used since it produces `#define yydebug
3430         foodebug'.
3431
3432         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3433         (YYDPRINTF): New macro.
3434         Spread its use.
3435         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3436         the bison options.
3437         Also test `--verbose', `--defines' and `--name-prefix'.
3438
3439 2000-10-02  Akim Demaille  <akim@epita.fr>
3440
3441         Improve the readability of the produced parsers.
3442
3443         * src/bison.s1: Formatting changes.
3444         Improve the comment related to the `$' mark.
3445         (yydefault): Don't fall through to `yyresume': `goto' there.
3446         * src/output.c (output_parser): When the `$' is met, skip the end
3447         of its line.
3448         New variable, `number_of_dollar_signs', to check there's exactly
3449         one `$' in the parser skeleton.
3450
3451 2000-10-02  Akim Demaille  <akim@epita.fr>
3452
3453         * lib/xstrdup.c: New file, from the fileutils.
3454         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3455         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3456         instead of strlen + xmalloc + strcpy.
3457         * src/symtab.c (copys): Remove, use xstrdup instead.
3458
3459 2000-10-02  Akim Demaille  <akim@epita.fr>
3460
3461         * src/gram.h (associativity): New enum type which replaces the
3462         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3463         `right_assoc', `left_assoc' and `non_assoc'.
3464         Adjust all dependencies.
3465         * src/reader.c: Formatting changes.
3466         (LTYPESTR): Don't define it, use it as a literal in
3467         `reader_output_yylsp'.
3468         * src/symtab.h (symbol_class): New enum type which replaces the
3469         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3470         `sunknown', `stoken and `snterm'.
3471
3472 2000-10-02  Akim Demaille  <akim@epita.fr>
3473
3474         * src/getargs.c (fixed_outfiles): Rename as...
3475         (yaccflag): for consistency and accuracy.
3476         Adjust dependencies.
3477
3478 2000-10-02  Akim Demaille  <akim@epita.fr>
3479
3480         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3481         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3482         difficult and introduced a lot of core dump.  It turns out that
3483         Bison used an implementation of `xmalloc' based on `calloc', and
3484         at various places it does depend upon the initialization to 0.  I
3485         have not tried to isolate the pertinent places, and all the former
3486         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3487         someone should address this issue.
3488
3489         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3490         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
3491         files.
3492         Adjust dependencies.
3493         * src/warshall.h: New file.
3494         Propagate.
3495
3496 2000-10-02  Akim Demaille  <akim@epita.fr>
3497
3498         Various anti-`extern in *.c' changes.
3499
3500         * src/system.h: Include `assert.h'.
3501
3502 2000-10-02  Akim Demaille  <akim@epita.fr>
3503
3504         * src/state.h (nstates, final_state, first_state, first_shift)
3505         (first_reduction): Move their exportation from here...
3506         * src/LR0.h: to here.
3507         Adjust dependencies.
3508         * src/getargs.c (statisticsflag): New variable.
3509         Add support for `--statistics'.

3511
3512         Remove a lot of now useless `extern' statements in most files.

3581
3582 2000-10-02  Akim Demaille  <akim@epita.fr>
3583
3584         * src/output.c (token_actions): Introduce a temporary array,
3585         YYDEFACT, that makes it possible for this function to use
3586         output_short_table.
3587
3588 2000-10-02  Akim Demaille  <akim@epita.fr>
3589
3590         `user_toknums' is output as a `short[]' in `output.c', while it is
3591         defined as a `int[]' in `reader.c'.  For consistency with the
3592         other output tables, `user_toknums' is now defined as a table of
3593         shorts.

3776         * configure.in: Adjust.
3777         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

3800         * src/Makefile.am (bison.simple): Fix the awk program: quote only
3801         the file name, not the whole `#line LINE FILE'.
3802
3803 2000-03-17  Akim Demaille  <akim@epita.fr>
3804
3805         On syntax errors, report the token on which we choked.
3806
3807         * src/bison.s1 (yyparse): In the label yyerrlab, when

3825

3827         copy_comment.  Removed now unused `match', `ended',
3828         `cplus_comment'.
3829         (copy_comment, copy_string): Moved, to be visible from
3830         copy_definition.
3831

3833
3834         * src/reader.c (copy_string): Declare `static inline'.  No

3856
3857         Change the handling of @s so that they behave exactly like $s.
3858         There is now a pseudo variable @$ (readble and writable), location
3859         of the lhs of the rule (by default ranging from the location of
3860         the first symbol of the rhs, to the location of the last symbol,
3861         or, if the rhs is empty, YYLLOC).
3862
3863         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3864         yyval.
3865         (yyparse): When providing a default semantic action, provide a
3866         default location action.
3867         (after the $): No longer change `*YYLSP', just stack YYLOC the
3868         same way you stack YYVAL.
3869         * src/reader.c (read_declarations): Use warns.
3870         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3871         (copy_action, case '@'): Likewise.
3872         Use a standard error message, to save useless work from
3873         translators.
3874
3875 2000-03-17  Akim Demaille  <akim@epita.fr>
3876

3894
3895         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
3896         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3897         One `#if YYDEBUG' remains, since it uses variables which are
3898         defined only if `YYDEBUG != 0'.
3899
3900 2000-03-16  Akim Demaille  <akim@epita.fr>

3926         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

3932         the proper line number and file name.
3933         (DEFS): Propagate the location of bison library files and of the
3934         locale files.
3935         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
3936         builddir.
3937         * acinclude.m4: Remove, replaced by the directory m4.
3938         * m4/Makefile.am (EXTRA_DIST): New variable.
3939         * m4/gettext.m4: New file, from the fileutils.

3947         Formatting changes of various comments.
3948         Respect the GNU coding standards at various places.
3949         Don't use `_()' when no translation is needed.

3952
3953         * src/files.c:
