ChangeLog

   1 2001-12-15  Akim Demaille  <akim@epita.fr>
   2
   3         Still making progress in separating Bison into (i) input, (ii)
   4         process, (iii) output: now we can directly output the parser file
   5         without using table_obstack at all.
   6
   7         * src/files.c, src/files.h (table_obstack): Bye bye.
   8         (parser_file_name): New.
   9         * src/files.c (compute_output_file_names): Compute it.
  10         * src/output.c (actions_output, output_parser)
  11         (output_master_parser): To a file instead of an obstack.
  12
  13 2001-12-15  Akim Demaille  <akim@epita.fr>
  14
  15         Attach actions to rules, instead of pre-outputting them to
  16         actions_obstack.
  17
  18         * src/gram.h (rule_t): action and action_line are new members.
  19         * src/reader.c (symbol_list): Likewise.
  20         (copy_action): Save the actions within the rule.
  21         (packgram): Save them in rule_table.
  22         * src/output.c (actions_output): New.
  23         (output_parser): Use it on `%%actions'.
  24         (output_rule_data): Don't free rule_table.
  25         (output): Do it.
  26         (prepare): Don't save the `action' muscle.
  27         * src/bison.simple: s/%%action/%%actions/.
  28
  29 2001-12-15  Akim Demaille  <akim@epita.fr>
  30
  31         * src/reader.c (copy_action): When --yacc, don't append a `;'
  32         to the user action: let it fail if lacking.
  33         Suggested by Aharon Robbins and Tom Tromey.
  34
  35 2001-12-14  Akim Demaille  <akim@epita.fr>
  36
  37         * src/lex.c (literalchar): Simply return the char you decoded, non
  38         longer mess around with obstacks and int pointers.
  39         Adjust all callers.
  40
  41 2001-12-14  Akim Demaille  <akim@epita.fr>
  42
  43         * src/lex.c (literalchar): Don't escape the special characters,
  44         just decode them, and keep them as char (before, eol was output as
  45         the 2 char string `\n' etc.).
  46         * src/output.c (output_rule_data): Use quotearg to output the
  47         token strings.
  48
  49 2001-12-13  Paul Eggert  <eggert@twinsun.com>
  50
  51         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
  52         Do not infringe on the global user namespace when using C++.
  53         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
  54         All uses of `fprintf' and `stderr' changed.
  55
  56         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
  57
  58 2001-12-13  Akim Demaille  <akim@epita.fr>
  59
  60         The computation of nullable is broken: it doesn't handle empty
  61         RHS's properly.
  62
  63         * tests/torture.at (GNU AWK Grammar): New.
  64         * tests/sets.at (Nullable): New.
  65         * src/nullable.c (set_nullable): Instead of blindly looping over
  66         `ritems', loop over the rules, and then over their rhs's.
  67
  68         Work around Autotest bugs.
  69
  70         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
  71         frame, because Autotest understand lines starting with a `+' as
  72         traces from the shell.  Then, they are not processed properly.
  73         Admittedly an Autotest bug, but we don't have time to wait for
  74         Autotest to catch up.
  75         * tests/regression.at (Broken Closure): Adjust to the new table
  76         frames.
  77         Move to...
  78         * tests/sets.at: here.
  79
  80 2001-12-13  Akim Demaille  <akim@epita.fr>
  81
  82         * src/closure.c (closure): Use nrules instead of playing tricks
  83         with BITS_PER_WORD.
  84
  85 2001-12-13  Akim Demaille  <akim@epita.fr>
  86
  87         * src/print.c (print_actions): Output the handling of `$' as the
  88         traces do: shifting the token EOF.  Before EOF was treated as a
  89         nonterminal.
  90         * tests/regression.at: Adjust some tests.
  91         * src/print_graph.c (print_core): Complete the set of items via
  92         closure.  The next-to-final and final states are still unsatisfying,
  93         but that's to be addressed elsewhere.
  94         No longer output the rule numbers, but do output the state number.
  95         A single loop for the shifts + gotos is enough, but picked a
  96         distinct color for each.
  97         (print_graph): Initialize and finalize closure.
  98
  99 2001-12-13  Akim Demaille  <akim@epita.fr>
 100
 101         * src/reader.c (readgram): Remove dead code, an strip useless
 102         braces.
 103         (get_type): Remove, unused.
 104
 105 2001-12-12  Akim Demaille  <akim@epita.fr>
 106
 107         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
 108         on that of lib/error.c.
 109
 110 2001-12-12  Akim Demaille  <akim@epita.fr>
 111
 112         Some hosts don't like `/' in includes.
 113
 114         * src/system.h: Include libgettext.h without qualifying the path.
 115         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
 116         $(top_srcdir).
 117
 118 2001-12-11  Marc Autret  <autret_m@epita.fr>
 119
 120         * src/output.c (output_parser): Remove useless muscle.
 121
 122 2001-12-11  Marc Autret  <autret_m@epita.fr>
 123
 124         * src/bison.simple: Remove #line just before %%epilogue. It
 125         is now handled in ...
 126         * src/reader.c (read_additionnal_code): Add the output of a
 127         #line for the epilogue.
 128
 129 2001-12-10  Marc Autret  <autret_m@epita.fr>
 130
 131         * src/reader.c (copy_definition): Re-use CPP-outed code which
 132         replace precedent remove.
 133         * src/bison.simple: Remove #line before %%prologue because
 134         %%input-line is wrong at this time.
 135
 136 2001-12-10  Marc Autret  <autret_m@epita.fr>
 137
 138         * src/reader.c (symbols_output): Clean up.
 139         * src/output.c (output_gram, output): Clean up.
 140
 141 2001-12-10  Akim Demaille  <akim@epita.fr>
 142
 143         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
 144         * src/LR0.c (set_state_table): here.
 145         * src/lalr.c (lalr): Call it.
 146
 147 2001-12-10  Akim Demaille  <akim@epita.fr>
 148
 149         * src/state.h (shifts): Remove the `number' member: shifts are
 150         attached to state, hence no longer need to be labelled with a
 151         state number.
 152
 153 2001-12-10  Akim Demaille  <akim@epita.fr>
 154
 155         Now that states have a complete set of members, the linked list of
 156         shifts is useless: just fill directly the state's shifts member.
 157
 158         * src/state.h (shifts): Remove the `next' member.
 159         * src/LR0.c (first_state, last_state): Remove.
 160         Adjust the callers.
 161         (augment_automaton): Don't look for the shifts that must be added
 162         a shift on EOF: it is those of the state we looked for!  But now,
 163         since shifts are attached, it is no longer needed to looking
 164         merely by its id: its number.
 165
 166 2001-12-10  Akim Demaille  <akim@epita.fr>
 167
 168         * src/LR0.c (augment_automaton): Better variable locality.
 169         Remove an impossible branch: if there is a state corresponding to
 170         the start symbol being shifted, then there is shift for the start
 171         symbol from the initial state.
 172
 173 2001-12-10  Akim Demaille  <akim@epita.fr>
 174
 175         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
 176         only when appropriate: when insert_start_shifting_state' is not
 177         invoked.
 178         * tests/regression.at (Rule Line Numbers): Adjust.
 179
 180 2001-12-10  Akim Demaille  <akim@epita.fr>
 181
 182         * src/LR0.c (augment_automaton): Now that all states have shifts,
 183         merge the two cases addition shifts to the initial state.
 184
 185 2001-12-10  Akim Demaille  <akim@epita.fr>
 186
 187         * src/lalr.c (set_state_table): Move to...
 188         * src/LR0.c: here.
 189         * src/lalr.c (lalr): Don't call it...
 190         * src/LR0.c (generate_states): do it.
 191         * src/LR0.h (first_state): Remove, only the table is used.
 192
 193 2001-12-10  Akim Demaille  <akim@epita.fr>
 194
 195         * src/LR0.h (first_shift, first_reduction): Remove.
 196         * src/lalr.c: Don't use first_shift: find shifts through the
 197         states.
 198
 199 2001-12-10  Akim Demaille  <akim@epita.fr>
 200
 201         * src/LR0.c: Attach shifts to states as soon as they are
 202         computed.
 203         * src/lalr.c (set_state_table): Instead of assigning shifts to
 204         state, just assert that the mapping was properly done.
 205
 206 2001-12-10  Akim Demaille  <akim@epita.fr>
 207
 208         * src/LR0.c (insert_start_shift): Rename as...
 209         (insert_start_shifting_state): this.
 210         (insert_eof_shifting_state, insert_accepting_state): New.
 211         (augment_automaton): Adjust.
 212         Better locality of the variables.
 213         When looking if the start_symbol is shifted from the initial
 214         state, using `while (... symbol != start_symbol ...)' sounds
 215         better than `while (... symbol < start_symbol ...)': If fail
 216         to see how the order between symbols could be relevant!
 217
 218 2001-12-10  Akim Demaille  <akim@epita.fr>
 219
 220         * src/getargs.h: Don't declare `spec_name_prefix' and
 221         `spec_file_prefix', declared by src/files.h.
 222         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
 223         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
 224         * src/output.c (prepare): Adjust.
 225         * src/reader.c (symbols_output): Likewise.
 226         * src/vmsgetargs.c: Vaguely adjust, but who cares?
 227
 228 2001-12-10  Akim Demaille  <akim@epita.fr>
 229
 230         * src/muscle_tab.c (muscle_init): NULL is a better default than
 231         `"0"'.
 232
 233 2001-12-10  Akim Demaille  <akim@epita.fr>
 234
 235         * src/reader.c (reader): Calling symbols_output once is enough.
 236
 237 2001-12-10  Akim Demaille  <akim@epita.fr>
 238
 239         Now that states have a complete set of members, the linked list of
 240         reductions is useless: just fill directly the state's reductions
 241         member.
 242
 243         * src/state.h (struct reductions): Remove member `number' and
 244         `next'.
 245         * src/LR0.c (first_reduction, last_reduction): Remove.
 246         (save_reductions): Don't link the new reductions, store them in
 247         this_state.
 248         * src/lalr.c (set_state_table): No need to attach reductions to
 249         states, it's already done.
 250         * src/output.c (output_actions): No longer free the shifts, then
 251         the reductions, then the states: free all the states and their
 252         members.
 253
 254 2001-12-10  Akim Demaille  <akim@epita.fr>
 255
 256         * src/options.c (OPTN, DRTV, BOTH): New.
 257         (option_table): Use them.
 258
 259         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
 260         the job of system.h.
 261         * src/options.c: Don't include stdio.h and xalloc.h for the same
 262         reasons.
 263
 264 2001-12-10  Akim Demaille  <akim@epita.fr>
 265
 266         * src/output.c (output, prepare): Make sure the values of the
 267         muscles `action' and `prologue' are 0-terminated.
 268
 269 2001-12-10  Akim Demaille  <akim@epita.fr>
 270
 271         Clean up GCC warnings.
 272
 273         * src/reader.c (copy_action): `buf' is not used.
 274         (parse_skel_decl): Be static.
 275         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
 276         * src/options.h (create_long_option_table): Have a real prototype.
 277         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
 278         (hash_delete_at): Return const void *.
 279         Adjust casts to preserve the const.
 280
 281 2001-12-10  Akim Demaille  <akim@epita.fr>
 282
 283         * configure.in: Require 2.52g.
 284         M4 is not needed, but AUTOM4TE is.
 285         * m4/m4.m4: Remove.
 286         * tests/Makefile.am: Adjust.
 287
 288 2001-12-10  Akim Demaille  <akim@epita.fr>
 289
 290         One structure for states is enough, even though theoretically
 291         there are LR(0) states and LALR(1) states.
 292
 293         * src/lalr.h (state_t): Remove.
 294         (state_table): Be state_t **, not state_t *.
 295         * src/state.h (core, CORE_ALLOC): Rename as...
 296         (state_t, STATE_ALLOC): this.
 297         Add the LALR(1) members: shifts, reductions, errs.
 298         * src/LR0.c (state_table): Rename as...
 299         (state_hash): this, to avoid name clashes with the global
 300         `state_table'.
 301         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
 302         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
 303
 304 2001-12-10  Akim Demaille  <akim@epita.fr>
 305
 306         Bison dumps core on bash.y.
 307         Reported by Pascal Bart.
 308
 309         * src/warshall.c (bitmatrix_print): New.
 310         (TC): Use it.
 311         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
 312         j must be the outer loop.
 313         * tests/regression.at (Broken Closure): New.
 314
 315 2001-12-05  Akim Demaille  <akim@epita.fr>
 316
 317         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 318         its argument.
 319         Reported by Peter Hámorský.
 320
 321 2001-12-05  Akim Demaille  <akim@epita.fr>
 322
 323         * src/conflicts.c (err_table): Remove.
 324         (resolve_sr_conflict): Adjust.
 325         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 326         Rename as...
 327         (state_t.reductions, state_t.shifts): this.
 328
 329 2001-12-05  Akim Demaille  <akim@epita.fr>
 330
 331         * src/reduce.c (reduce_grammar_tables): No longer disable the
 332         removal of useless rules via CPP but via `if (0)', so that the
 333         compiler still check the code is valid.
 334         For instance, it should have noticed `rline' no longer exists: use
 335         the `line' member of rule_t.
 336         * src/gram.c (dummy, rline): Remove, unused.
 337
 338 2001-12-05  Akim Demaille  <akim@epita.fr>
 339
 340         * src/output.c (pack_vector): Use assert, not berror.
 341         * src/main.c (berror): Remove, unused.
 342
 343 2001-12-05  Akim Demaille  <akim@epita.fr>
 344
 345         New experimental feature: if --verbose --trace output all the
 346         items of a state, not only its kernel.
 347
 348         * src/print.c (print_core): If `trace_flag', then invoke closure
 349         before outputting the items of the state (print_core is no longer
 350         a correct name them).
 351         (print_results): Invoke new_closure/free_closure if needed.
 352
 353 2001-12-05  Akim Demaille  <akim@epita.fr>
 354
 355         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 356         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 357         (nitemset): for consistency with the rest of the project.
 358
 359 2001-12-05  Akim Demaille  <akim@epita.fr>
 360
 361         * src/closure.c (print_closure): Improve.
 362         (closure): Use it for printing input and output.
 363
 364 2001-12-05  Akim Demaille  <akim@epita.fr>
 365
 366         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 367         indexed by nonterminals.
 368
 369 2001-12-05  Akim Demaille  <akim@epita.fr>
 370
 371         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 372         what it was!).
 373         * src/warshall.h: Remove accidental duplication of the content.
 374
 375 2001-12-05  Akim Demaille  <akim@epita.fr>

 386
 387 2001-12-05  Akim Demaille  <akim@epita.fr>
 388
 389         * src/output.c (action_row): De-obfuscate
 390         using the good o' techniques: arrays not pointers, variable
 391         locality, BITISSET, RESETBIT etc.
 392
 393 2001-12-05  Akim Demaille  <akim@epita.fr>
 394
 395         Pessimize the code to simplify it: from now on, all the states
 396         have a valid SHIFTS, which NSHIFTS is possibly 0.
 397
 398         * src/LR0.c (shifts_new): Be global and move to..
 399         * src/state.c, src/state.h: here.
 400         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 401         * src/print_graph: Adjust.
 402
 403 2001-12-05  Akim Demaille  <akim@epita.fr>
 404
 405         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 406         * src/conflicts.c: Use it.
 407         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 408         incorrectly ``simplified''.
 409
 410 2001-12-05  Akim Demaille  <akim@epita.fr>
 411
 412         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
 413         using the good o' techniques: arrays not pointers, variable
 414         locality, BITISSET, RESETBIT etc.
 415
 416 2001-12-05  Akim Demaille  <akim@epita.fr>
 417
 418         * src/state.h (SHIFT_SYMBOL): New.
 419         * src/conflicts.c: Use it to deobfuscate.
 420
 421 2001-12-05  Akim Demaille  <akim@epita.fr>
 422
 423         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
 424         (print_reductions): De-obfuscate using the good o' techniques:
 425         arrays not pointers, variable locality, BITISSET.
 426
 427 2001-12-05  Akim Demaille  <akim@epita.fr>
 428
 429         * src/conflicts.c (print_reductions): Arrays, not pointers.
 430         Use BITISSET.

 432 2001-12-05  Akim Demaille  <akim@epita.fr>
 433
 434         * src/conflicts.c (print_reductions): Pessimize, but clarify.

 452
 453 2001-12-05  Akim Demaille  <akim@epita.fr>
 454
 455         * src/LR0.c (augment_automaton): Formatting changes.
 456         Better variable locality.
 457
 458 2001-12-05  Akim Demaille  <akim@epita.fr>
 459
 460         * src/lalr.c (matrix_print): New.
 461         (transpose): Use it.
 462         Use arrays instead of pointers.
 463
 464 2001-12-05  Akim Demaille  <akim@epita.fr>
 465
 466         * src/lalr.c (maxrhs): Move to...
 467         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
 468         * src/lalr.c (build_relations): Adjust.
 469
 470 2001-12-05  Akim Demaille  <akim@epita.fr>
 471
 472         * src/lalr.c (transpose): Free the memory allocated to the
 473         argument, as it is replaced by the results by the unique caller.
 474         (build_relations): Merely invoke transpose: it handles the memory
 475         deallocation.
 476         Improve variable locality.
 477         Avoid variables used as mere abbreviations.
 478         (compute_lookaheads): Use arrays instead of pointers.
 479
 480 2001-12-05  Akim Demaille  <akim@epita.fr>
 481
 482         * src/lalr.c (initialize_F): Improve variable locality.
 483         Avoid variables used as mere abbreviations.
 484
 485 2001-12-05  Akim Demaille  <akim@epita.fr>
 486
 487         * src/derives.c (print_derives): Display the ruleno.
 488         * src/lalr.c (initialize_F, transpose): Better variable locality
 489         to improve readability.
 490         Avoid variables used as mere abbreviations.
 491
 492 2001-12-05  Akim Demaille  <akim@epita.fr>
 493
 494         * src/lalr.c (traverse): Use arrays instead of pointers.
 495
 496 2001-12-05  Akim Demaille  <akim@epita.fr>
 497
 498         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
 499         the handling of squeue.
 500         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 501
 502 2001-12-05  Akim Demaille  <akim@epita.fr>
 503
 504         Because useless nonterminals are now kept alive (instead of being
 505         `destroyed'), we now sometimes examine them, and store information
 506         related to them.  Hence we need to know their number, and adjust
 507         memory allocations.
 508
 509         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
 510         static.
 511         * src/LR0.c (allocate_itemsets): The memory allocated to
 512         `symbol_count' was used for two different purpose: once to count
 513         the number of occurrences of each symbol, and later reassigned to
 514         `shift_symbol', containing the symbol that can be shifted from a
 515         given state.
 516         Deobfuscate, i.e., allocate, use and free `symbol_count' here
 517         only, and...
 518         (new_itemsets): Allocate `shift_symbol' here.
 519         (allocate_itemsets): symbol_count includes useless nonterminals.
 520         Make room for them.
 521         (free_storage): Use `free', not `XFREE', for pointers that cannot
 522         be null.
 523
 524 2001-12-05  Akim Demaille  <akim@epita.fr>
 525
 526         * src/nullable.c (set_nullable): Deobfuscate the handling of
 527         ritem.
 528         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 529
 530 2001-12-05  Akim Demaille  <akim@epita.fr>
 531
 532         * src/gram.c, src/gram.h (ritem_print): New.
 533         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
 534         (This useless function was defined only to work around VMS linkers
 535         that can't handle compilation units with variables only).
 536         * src/reduce.c (dump_grammar): Use it to trace the construction of
 537         ritem.
 538
 539 2001-12-04  Paul Eggert  <eggert@twinsun.com>
 540
 541         * src/bison.simple (union yyalloc): Change member names
 542         to be the same as the stack names.
 543         (yyparse): yyptr is now union yyalloc *, not char *.
 544         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
 545         and may generate better code on some machines.
 546         (yystpcpy): Use prototype if __STDC__ is defined, not just
 547         if __cplusplus is defined.
 548
 549 2001-11-30  Akim Demaille  <akim@epita.fr>
 550
 551         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
 552         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
 553         Gettext doesn't compile cleanly, and dies with -Werror.
 554         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
 555         Include WARNING_CFLAGS here.
 556         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
 557         before being defined.
 558
 559 2001-11-27  Paul Eggert  <eggert@twinsun.com>
 560
 561         * lib/quotearg.h (quotearg_n, quotearg_n_style):
 562         First arg is int, not unsigned.
 563         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
 564         (SIZE_MAX, UINT_MAX): New macros.
 565         (quotearg_n_options): Abort if N is negative.
 566         Avoid overflow check on hosts where size_t is 64 bits and int
 567         is 32 bits, as overflow is impossible there.
 568         Fix off-by-one typo that caused unnecessary reallocation.
 569
 570 2001-11-29  Paul Eggert  <eggert@twinsun.com>
 571
 572         Name space cleanup in generated parser.
 573
 574         * doc/bison.texinfo (Bison Parser): Discuss system headers
 575         and their effect on the user name space.
 576
 577         * src/bison.simple:
 578         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
 579         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
 580         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
 581
 582         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
 583         on user names when possible.
 584
 585         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
 586         Simplify test for whather <alloca.h> exists.
 587
 588         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
 589
 590         (<stdio.h>): Include if YYDEBUG.
 591
 592         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
 593         ! defined (yyoverflow) && ! defined (yymemcpy).
 594
 595         (yymemcpy, yyparse): Rename local variables as needed so that
 596         they all begin with 'yy'.
 597
 598         (yystrlen, yystpcpy): New functions.
 599
 600         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
 601         All uses changed.
 602
 603         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
 604         instead of relying on string.h functions.  Use YYSTACK_ALLOC
 605         and YYSTACK_FREE instead of malloc and free.
 606
 607 2001-11-30  Akim Demaille  <akim@epita.fr>
 608
 609         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
 610         before their first uses.
 611         (YYBISON, YYPURE): Move to the top of the output.
 612
 613 2001-11-30  Akim Demaille  <akim@epita.fr>

 616
 617 2001-11-30  Akim Demaille  <akim@epita.fr>
 618
 619         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
 620         if body instead of `;' to pacify GCC's warnings.
 621
 622 2001-11-30  Akim Demaille  <akim@epita.fr>
 623
 624         Instead of mapping the LHS of unused rules to -1, keep the LHS
 625         valid, but flag the rules as invalid.
 626
 627         * src/gram.h (rule_t): `useful' is a new member.
 628         * src/print.c (print_grammar): Adjust.
 629         * src/derives.c (set_derives): Likewise.
 630         * src/reader.c (packgram, reduce_output): Likewise.
 631         * src/reduce.c (reduce_grammar_tables): Likewise.
 632         * tests/reduce.at (Underivable Rules, Useless Rules): New.

 634 2001-11-30  Akim Demaille  <akim@epita.fr>
 635
 636         * src/reduce.c (reduce_output): Formatting changes.

 639         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
 640
 641 2001-11-30  Akim Demaille  <akim@epita.fr>
 642
 643         * src/reduce.c (nonterminals_reduce): Instead of throwing away
 644         useless nonterminals, move them at the end of the symbol arrays.
 645         (reduce_output): Adjust.
 646         * tests/reduce.at (Useless Nonterminals): Adjust.
 647
 648 2001-11-30  Akim Demaille  <akim@epita.fr>
 649
 650         * src/reduce.c: Various comment/formatting changes.
 651         (nonterminals_reduce): New, extracted from...
 652         (reduce_grammar_tables): here.
 653         (reduce_grammar): Call nonterminals_reduce.
 654
 655 2001-11-29  Paul Eggert  <eggert@twinsun.com>

 659         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
 660         New macros.
 661         (union yyalloc): New type.
 662         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
 663         an arbitrary restriction on hosts where size_t is wider than int.
 664
 665         (yyparse): Don't dump core if alloca or malloc fails; instead, report
 666         a parser stack overflow.  Allocate just one block of memory for all
 667         three stacks, instead of allocating three blocks; this typically is
 668         faster and reduces fragmentation.
 669
 670         Do not limit the number of items in the stack to a value that fits
 671         in 'int', as this is an arbitrary limit on hosts with 64-bit
 672         size_t and 32-bit int.
 673
 674 2001-11-29  Marc Autret  <autret_m@epita.fr>
 675
 676         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
 677         of defining YYERROR_VERBOSE.
 678         [AT_DATA]: $4 is now out of C declarations in the prologue.
 679
 680 2001-11-28  Marc Autret  <autret_m@epita.fr>

 683         (parse_skel_decl): Use it.
 684         * src/lex.h: Add its prototype.
 685         * src/lex.c (literalchar): Become not static.
 686
 687 2001-11-28  Marc Autret  <autret_m@epita.fr>
 688
 689         * src/output.h: And put its extern declaration here.
 690         * src/output.c (error_verbose): Define here.
 691         (prepare): Echo name modification.
 692         * src/getargs.h: Clean its extern declaration.
 693         * src/getargs.c (error_verbose_flag): Remove.
 694         (getargs): Remove case 'e'.
 695         * src/options.c (option_table): 'error-verbose' is now seen as simple
 696         percent option.
 697         Include output.h.
 698
 699         * src/reader.c (read_declarations): Remove case tok_include.
 700         (parse_include_decl): Remove.
 701         * src/lex.h (token_t): Remove tok_include.
 702         * src/options.c (option_table): 'include' is now a simple command line
 703         option.
 704
 705 2001-11-28  Marc Autret  <autret_m@epita.fr>
 706
 707         * src/bison.simple: Adjust muscle names.
 708         * src/muscle_tab.c (muscle_init): Also rename the muscles.
 709         * src/output.c (prepare): s/_/-/ for the muscles names.
 710         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
 711
 712 2001-11-28  Marc Autret  <autret_m@epita.fr>
 713

 722 2001-11-28  Akim Demaille  <akim@epita.fr>
 723
 724         * src/closure.c (closure): `b' and `ruleno' denote the same value:
 725         keep ruleno only.
 726
 727 2001-11-28  Akim Demaille  <akim@epita.fr>
 728
 729         * src/closure.c (closure): Instead of looping over word in array
 730         then bits in words, loop over bits in array.
 731
 732 2001-11-28  Akim Demaille  <akim@epita.fr>
 733
 734         * src/closure.c (closure): No longer optimize the special case
 735         where all the bits of `ruleset[r]' are set to 0, to make the code
 736         clearer.
 737
 738 2001-11-28  Akim Demaille  <akim@epita.fr>
 739
 740         * src/closure.c (closure): `r' and `c' are new variables, used to
 741         de-obfuscate accesses to RULESET and CORE.
 742
 743 2001-11-28  Akim Demaille  <akim@epita.fr>

2488         import in Bison features implemented in 2.49c since 2.13.

2525         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
2526         `%debug'.
2527         Handle the actions for `%semantic_parser' and `%pure_parser' here,
2528         instead of returning a token.
2529         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
2530         * src/reader.c (read_declarations): Adjust.
2531         * src/files.c (open_files): Don't call `compute_base_names', don't

2673         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it

2675         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
2676         cast the value to (void *): assigning a `foo *' to a `void *'

2894         * src/derives.c, src/print.c, src/reduce.c: To ease the
2895         translation, move some `\n' out of the translated strings.
2896
2897 2000-10-02  Akim Demaille  <akim@epita.fr>
2898
2899         The location tracking mechanism is precious for parse error
2900         messages.  Nevertheless, it is enabled only when `@n' is used in
2901         the grammar, which is a different issue (you can use it in error
2902         message, but not in the grammar per se).  Therefore, there should
2903         be another means to enable it.
2904
2905         * src/getargs.c (getargs): Support `--locations'.
2906         (usage): Report it.
2907         * src/getargs.h (locationsflag): Export it.
2908         * src/lex.c (percent_table): Support `%locations'.
2909         * src/reader.c (yylsp_needed): Remove this variable, now replaced
2910         with `locationsflag'.
2911         * doc/bison.texinfo: Document `--locations' and `%locations'.
2912         Sort the options.
2913         * tests/calc.m4: Test it.
2914
2915         For regularity of the names, replace each
2916         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2917         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2918         In addition replace each `flag' with `_flag'.
2919
2920 2000-10-02  Akim Demaille  <akim@epita.fr>
2921
2922         Also test parse error messages, including with YYERROR_VERBOSE.
2923
2924         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2925         associative).
2926         Use it to check the computations.
2927         Use it to check `nonassoc' is honored.
2928         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2929         `--yyerror-verbose'.
2930         (_AT_CHECK_CALC): Adjust to this option.
2931         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2932
2933 2000-10-02  Akim Demaille  <akim@epita.fr>
2934
2935         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
2936         the latter demonstrates a flaw in the handling of non debugging
2937         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2938         was used in order to simplify:
2939
2940         #if YYDEBUG
2941         if (yydebug)
2942         {
2943         ...
2944         }
2945         #endif
2946
2947         into
2948
2949         if (yydebug)
2950         {
2951         ...
2952         }
2953
2954         unfortunately this leads to a CPP conflict when
2955         `--name-prefix=foo' is used since it produces `#define yydebug
2956         foodebug'.
2957
2958         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2959         (YYDPRINTF): New macro.
2960         Spread its use.
2961         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2962         the bison options.
2963         Also test `--verbose', `--defines' and `--name-prefix'.
2964
2965 2000-10-02  Akim Demaille  <akim@epita.fr>
2966
2967         Improve the readability of the produced parsers.
2968
2969         * src/bison.s1: Formatting changes.
2970         Improve the comment related to the `$' mark.
2971         (yydefault): Don't fall through to `yyresume': `goto' there.
2972         * src/output.c (output_parser): When the `$' is met, skip the end
2973         of its line.
2974         New variable, `number_of_dollar_signs', to check there's exactly
2975         one `$' in the parser skeleton.
2976
2977 2000-10-02  Akim Demaille  <akim@epita.fr>
2978
2979         * lib/xstrdup.c: New file, from the fileutils.
2980         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2981         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2982         instead of strlen + xmalloc + strcpy.
2983         * src/symtab.c (copys): Remove, use xstrdup instead.
2984
2985 2000-10-02  Akim Demaille  <akim@epita.fr>
2986
2987         * src/gram.h (associativity): New enum type which replaces the
2988         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2989         `right_assoc', `left_assoc' and `non_assoc'.
2990         Adjust all dependencies.
2991         * src/reader.c: Formatting changes.
2992         (LTYPESTR): Don't define it, use it as a literal in
2993         `reader_output_yylsp'.
2994         * src/symtab.h (symbol_class): New enum type which replaces the
2995         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
2996         `sunknown', `stoken and `snterm'.
2997
2998 2000-10-02  Akim Demaille  <akim@epita.fr>
2999
3000         * src/getargs.c (fixed_outfiles): Rename as...
3001         (yaccflag): for consistency and accuracy.
3002         Adjust dependencies.
3003
3004 2000-10-02  Akim Demaille  <akim@epita.fr>
3005
3006         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3007         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
3008         difficult and introduced a lot of core dump.  It turns out that
3009         Bison used an implementation of `xmalloc' based on `calloc', and
3010         at various places it does depend upon the initialization to 0.  I
3011         have not tried to isolate the pertinent places, and all the former
3012         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
3013         someone should address this issue.
3014
3015         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3016         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
3017         files.
3018         Adjust dependencies.
3019         * src/warshall.h: New file.
3020         Propagate.
3021
3022 2000-10-02  Akim Demaille  <akim@epita.fr>
3023
3024         Various anti-`extern in *.c' changes.
3025
3026         * src/system.h: Include `assert.h'.
3027
3028 2000-10-02  Akim Demaille  <akim@epita.fr>
3029
3030         * src/state.h (nstates, final_state, first_state, first_shift)
3031         (first_reduction): Move their exportation from here...
3032         * src/LR0.h: to here.
3033         Adjust dependencies.
3034         * src/getargs.c (statisticsflag): New variable.
3035         Add support for `--statistics'.
3036         Adjust dependencies.
3037
3038         Remove a lot of now useless `extern' statements in most files.
3039

3048         Propagate its use.
3049         * src/print.c: Formatting and ordering changes.
3050         (verbose, terse): Replace with...

3084         Propagate its use.
3085
3086 2000-10-02  Akim Demaille  <akim@epita.fr>
3087
3088         * src/reader.h: New file.

3103
3104         * src/lalr.h: New file.
3105         Propagate its inclusion instead of prototypes and `extern'.
3106         * src/lalr.c: Formatting changes, topological sorting etc.
3107
3108 2000-10-02  Akim Demaille  <akim@epita.fr>
3109
3110         * src/output.c (token_actions): Introduce a temporary array,
3111         YYDEFACT, that makes it possible for this function to use
3112         output_short_table.
3113
3114 2000-10-02  Akim Demaille  <akim@epita.fr>
3115
3116         `user_toknums' is output as a `short[]' in `output.c', while it is
3117         defined as a `int[]' in `reader.c'.  For consistency with the
3118         other output tables, `user_toknums' is now defined as a table of
3119         shorts.
3120
3121         * src/reader.c (user_toknums): Be a short table instead of an int
3122         table.
3123         Adjust dependencies.

3131 2000-10-02  Akim Demaille  <akim@epita.fr>
3132
3133         * src/output.c (output): Topological sort of the functions, in
3134         order to get rid of the `static' prototypes.
3135         No longer use `register'.
3136         * src/output.h: New file.
3137         Propagate its inclusion in files explicitly prototyping functions
3138         from output.c.

3145

3147         * src/closure.c: Formatting changes, topological sort over the
3148         functions, use of closure.h.
3149         (initialize_closure, finalize_closure):  Rename as...
3150         (new_closure, free_closure): these.  Adjust dependencies.
3151         * src/LR0.c: Formatting changes, topological sort, use of
3152         cloture.h.
3153         (initialize_states): Rename as...

3159         * src/acconfig.h: Don't protect config.h against multiple
3160         inclusion.
3161         Don't define PARAMS.
3162         * src/system.h: Define PARAMS.
3163         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3164         purpose of config.h.  system.h must not try to fix wrong
3165         definitions in config.h.
3166
3167 2000-09-20  Akim Demaille  <akim@epita.fr>

3179         Use these macros to test bison with options `', `--raw',
3180         `--debug', `--yacc', `--yacc --debug'.
3181

3183
3184         * src/output.c: Formatting changes.

3189         * src/getargs.h: New file.
3190         Let all `extern' declarations about getargs.c be replaced with

3193
3194         * tests/calc.m4 (yyin): Be initialized in main, not on the global

3202         portable.
3203
3204 2000-09-18  Akim Demaille  <akim@epita.fr>
3205
3206         * configure.in: Append WARNING_CFLAGS to CFLAGS.
3207         * src/Makefile.am (INCLUDES): Don't.
3208         Be ready to fetch headers in lib/.
3209
3210 2000-09-18  Akim Demaille  <akim@epita.fr>
3211
3212         * doc/bison.texinfo: Update the copyright.

3243         (VERSION_STRING): Remove.
3244
3245 2000-04-14  Akim Demaille  <akim@epita.fr>
3246
3247         * src/reader.c (copy_comment2): New function, same as former
3248         `copy_comment', but outputs into two FILE *.
3249         (copy_comment): Use it.
3250         (parse_union_decl): Use it.
3251         (get_type, parse_start_decl): Use the same `invalid' message.

3327         the file name, not the whole `#line LINE FILE'.
3328
3329 2000-03-17  Akim Demaille  <akim@epita.fr>
3330
3331         On syntax errors, report the token on which we choked.

3353         copy_comment.  Removed now unused `match', `ended',
3354         `cplus_comment'.
3355         (copy_comment, copy_string): Moved, to be visible from

3382
3383         Change the handling of @s so that they behave exactly like $s.
3384         There is now a pseudo variable @$ (readble and writable), location
3385         of the lhs of the rule (by default ranging from the location of
3386         the first symbol of the rhs, to the location of the last symbol,
3387         or, if the rhs is empty, YYLLOC).
3388
3389         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3390         yyval.
3391         (yyparse): When providing a default semantic action, provide a
3392         default location action.
3393         (after the $): No longer change `*YYLSP', just stack YYLOC the
3394         same way you stack YYVAL.
3395         * src/reader.c (read_declarations): Use warns.
3396         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3397         (copy_action, case '@'): Likewise.
3398         Use a standard error message, to save useless work from
3399         translators.
3400
3401 2000-03-17  Akim Demaille  <akim@epita.fr>
3402

3420
3421         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
3422         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3423         One `#if YYDEBUG' remains, since it uses variables which are
3424         defined only if `YYDEBUG != 0'.
3425
3426 2000-03-16  Akim Demaille  <akim@epita.fr>

3450         handled via src/Makefile.am.

3452         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
3453         autoheader.

3458         the proper line number and file name.
3459         (DEFS): Propagate the location of bison library files and of the
3460         locale files.
3461         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
3462         builddir.
3463         * acinclude.m4: Remove, replaced by the directory m4.
3464         * m4/Makefile.am (EXTRA_DIST): New variable.
3465         * m4/gettext.m4: New file, from the fileutils.

4151         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4152         major changes to files.c.
4153         (lex) Retain in the incoming stream a character following
4154         an incorrect '/'.
4155         (skip_white_space, lex):  Revised most error messages
4156         and changed fatal to warn to avoid aborting.
