[bison.git] / ChangeLog
1 2001-12-29 Akim Demaille <akim@epita.fr>
2
3 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
4 user prologue. These are defaults.
5 * tests/actions.at (Mid-rule actions): Make sure the user can
6 define YYDEBUG and YYERROR_VERBOSE.
7
8
9 2001-12-29 Akim Demaille <akim@epita.fr>
10
11 * src/output.c (header_output): Don't forget to export YYLTYPE and
12 yylloc.
13 * tests/headers.at (export YYLTYPE): New, make sure it does.
14 * tests/regression.at (%union and --defines, Invalid CPP headers):
15 Move to...
16 * tests/headers.at: here.
17
18
19 2001-12-29 Akim Demaille <akim@epita.fr>
20
21 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
22
23
24 2001-12-29 Akim Demaille <akim@epita.fr>
25
26 * tests/actions.at (Mid-rule actions): Output on a single line
27 instead of several.
28
29
30 2001-12-29 Akim Demaille <akim@epita.fr>
31
32 * doc/bison.texinfo: Formatting changes.
33
34 2001-12-29 Akim Demaille <akim@epita.fr>
35
36 Don't store the token defs in a muscle, just be ready to output it
37 on command. Now possible via `symbols'. Fixes a memory leak.
38
39 * src/output.c (token_definitions_output): New.
40 (output_parser, header_output): Use it.
41 * src/reader.c (symbols_save): Remove.
42
43
44 2001-12-29 Akim Demaille <akim@epita.fr>
45
46 * src/bison.simple: Do not provide a default for YYSTYPE and
47 YYLTYPE before the user's prologue. Otherwise it's hardly... a
48 default.
49
50
51 2001-12-29 Akim Demaille <akim@epita.fr>
52
53 Mid-rule actions are simply... ignored!
54
55 * src/reader.c (readgram): Be sure to attach mid-rule actions to
56 the empty-rule associated to the dummy symbol, not to the host
57 rule.
58 * tests/actions.at (Mid-rule actions): New.
59
60
61 2001-12-29 Akim Demaille <akim@epita.fr>
62
63 Memory leak.
64
65 * src/reader.c (reader): Free grammar.
66
67 2001-12-29 Akim Demaille <akim@epita.fr>
68
69 Memory leak.
70
71 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
72 since it allocates it for each state, although only one is needed.
73 (allocate_storage): Do it here.
74
75
76 2001-12-29 Akim Demaille <akim@epita.fr>
77
78 * src/options.h, src/options.c (create_long_option_table): Rename
79 as...
80 (long_option_table_new): this, with a clearer prototype.
81 (percent_table): Remove, unused,
82 * src/getargs.c (getargs): Adjust.
83
84
85 2001-12-29 Akim Demaille <akim@epita.fr>

87 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
88 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
89 as states.
90
91
92 2001-12-29 Akim Demaille <akim@epita.fr>
93
94 * src/lalr.c (build_relations): Rename `states' as `states1'.
95 Sorry, I don't understand exactly what it is, no better name...
96
97
98 2001-12-29 Akim Demaille <akim@epita.fr>
99
100 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
101 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
102 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
103 as rules.
104
105
106 2001-12-29 Akim Demaille <akim@epita.fr>
107
108 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
109 ago.
110
111
112 2001-12-29 Akim Demaille <akim@epita.fr>
113
114 * src/reader.c, src/reader.h (user_toknums): Remove.
115 Adjust all users to use symbols[i]->user_token_number.
116
117
118 2001-12-29 Akim Demaille <akim@epita.fr>
119
120 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
121 Adjust all users to use symbols[i]->prec or ->assoc.
122
123
124 2001-12-29 Akim Demaille <akim@epita.fr>
125
126 * src/reader.c, src/reader.h (tags): Remove.
127 Adjust all users to use symbols[i]->tag.
128
129
130 2001-12-29 Akim Demaille <akim@epita.fr>
131
132 * src/gram.h, src/gram.c (symbols): New, similar to state_table
133 and rule_table.
134 * src/reader.c (packsymbols): Fill this table.
135 Drop sprec.
136 * src/conflicts.c (resolve_sr_conflict): Adjust.
137 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
138 single table.
139 Use symbols[i]->tag instead of tags[i].
140
141
142 2001-12-29 Akim Demaille <akim@epita.fr>
143
144 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
145 In addition, put a comment in there, to replace...
146 * tests/regression.at (%union and C comments): Remove.
147
148
149 2001-12-29 Akim Demaille <akim@epita.fr>
150
151 * tests/regression.at (Web2c Actions): Blindly move the actual
152 output as expected output. The contents *seem* right to me, but I
153 can't pretend reading perfectly parser tables... Nonetheless, all
154 the other tests pass correctly, the table look OK, even though the
155 presence of `$axiom' is to be noted: AFAICS it is useless (but
156 harmless).
157
158
159 2001-12-29 Akim Demaille <akim@epita.fr>
160
161 * src/reader.c (readgram): Don't add the rule 0 if there were no
162 rules read. In other words, add it _after_ having performed
163 grammar sanity checks.
164 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
165
166
167 2001-12-29 Akim Demaille <akim@epita.fr>
168
169 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
170 visible, and some states have now a different number.
171
172
173 2001-12-29 Akim Demaille <akim@epita.fr>
174
175 * src/reader.c (readgram): Bind the initial rule's lineno to that
176 of the first rule.
177 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
178 (Solved SR Conflicts): Adjust rule 0's line number.
179
180
181 2001-12-29 Akim Demaille <akim@epita.fr>
182
183 Fix the `GAWK Grammar' failure.
184
185 * src/LR0.c (final_state): Initialize to -1 so that we do compute
186 the reductions of the first state which was mistakenly confused
187 with the final state because precisely final_state was initialized
188 to 0.
189 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
190 now noticed by Bison.
191 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
192 have a reduction on $default.
193
194
195 2001-12-29 Akim Demaille <akim@epita.fr>
196
197 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
198 rule line numbers.
199 * src/closure.c (print_closure): Likewise.
200 * src/derives.c (print_derives): Likewise.
201 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
202 now.
203
204 2001-12-29 Akim Demaille <akim@epita.fr>
205
206 * src/lalr.c (lookaheads_print): New.
207 (lalr): Call it when --trace-flag.
208 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
209 are dumped.
210
211
212 2001-12-29 Akim Demaille <akim@epita.fr>
213
214 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
215 when walking through ritem, even via rule->rhs.
216 * src/reduce.c (dump_grammar, useful_production, reduce_output)
217 (useful_production, useless_nonterminals): Likewise.
218 (reduce_grammar_tables): Likewise, plus update nritems.
219 * src/nullable.c (set_nullable): Likewise.
220 * src/lalr.c (build_relations): Likewise.
221 * tests/sets.at (Nullable): Adjust.
222 Fortunately, now, the $axiom is no longer nullable.
223
224
225 2001-12-29 Akim Demaille <akim@epita.fr>
226
227 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
228 the 0-sentinel.
229 * src/gram.c (ritem_longest_rhs): Likewise.
230 * src/reduce.c (nonterminals_reduce): Likewise.
231 * src/print_graph.c (print_graph): Likewise.
232 * src/output.c (output_rule_data): Likewise.
233 * src/nullable.c (set_nullable): Likewise.
234
235 2001-12-29 Akim Demaille <akim@epita.fr>
236
237 * src/output.c: Comment changes.
238
239 2001-12-27 Paul Eggert <eggert@twinsun.com>
240
241 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
242 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
243 Sparc, as they were causing more porting problems than the
244 (minor) performance improvement was worth.
245
246 Also, catch up with 1.31's YYSTD.
247
248 2001-12-27 Akim Demaille <akim@epita.fr>
249
250 * src/output.c (output_gram): Rely on nritems, not the
251 0-sentinel. See below.
252 Use -1 as separator, not 0.
253 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
254 Rely on -1 as separator in yyrhs, instead of 0.
255 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
256 twice `Now at end of input', therefore there are two lines less to
257 expect.
258
259 2001-12-27 Akim Demaille <akim@epita.fr>
260
261 * tests/regression.at (Unresolved SR Conflicts):
262 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
263 below.
264
265 2001-12-27 Akim Demaille <akim@epita.fr>
266
267 * src/LR0.c (new_state): Recognize the final state by the fact it
268 is reached by eoftoken.
269 (insert_start_shifting_state, insert_eof_shifting_state)
270 (insert_accepting_state, augment_automaton): Remove, since now
271 these states are automatically computed from the initial state.
272 (generate_states): Adjust.
273 * src/print.c: When reporting a rule number to the user, substract
274 1, so that the axiom rule is rule 0, and the first user rule is 1.
275 * src/reduce.c: Likewise.
276 * src/print_graph.c (print_core): For the time being, just as for
277 the report, depend upon --trace-flags to dump the full set of
278 items.
279 * src/reader.c (readgram): Once the grammar read, insert the rule
280 0: `$axiom: START-SYMBOL $'.
281 * tests/set.at: Adjust: rule 0 is now displayed, and since the
282 number of the states has changed (the final state is no longer
283 necessarily the last), catch up.
284
285 2001-12-27 Akim Demaille <akim@epita.fr>
286
287 Try to make the use of the eoftoken valid. Given that its value
288 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
289 is used instead of > 0 where appropriate, (ii), depend upon nritems
290 instead of the 0-sentinel.
291
292 * src/gram.h, src/gram.c (nritems): New.
293 Expected to be duplication of nitems, but for the time being...
294 * src/reader.c (packgram): Assert nritems and nitems are equal.
295 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
296 * src/closure.c (print_closure, print_fderives): Likewise.
297 * src/gram.c (ritem_print): Likewise.
298 * src/print.c (print_core, print_grammar): Likewise.
299 * src/print_graph.c: Likewise.
300
301 2001-12-27 Akim Demaille <akim@epita.fr>
302
303 * src/main.c (main): If there are complains after grammar
304 reductions, then output the report anyway if requested, then die.
305 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
306 * src/reader.c (eoftoken): New.
307 (parse_token_decl): If the token being defined has value `0', it
308 is the eoftoken.
309 (packsymbols): No longer hack `tags' to insert `$' by hand.
310 Be sure to preserve the value of the eoftoken.
311 (reader): Make sure eoftoken is defined.
312 Initialize nsyms to 0: now eoftoken is created just like the others.
313 * src/print.c (print_grammar): Don't special case the eof token.
314 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
315 lie anyway, albeit pleasant.
316 * tests/calc.at: Exercise error messages with eoftoken.
317 Change the grammar so that empty input is invalid.
318 Adjust expectations.
319 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
320
321 2001-12-27 Akim Demaille <akim@epita.fr>
322
323 * configure.in: Check the protos of strchr ans strspn.
324 Replace strchr if needed.
325 * src/system.h: Provide the protos of strchr, strspn and memchr if
326 missing.
327 * lib/strchr.c: New.
328 * src/reader.c (symbols_save): Use strchr.
329
330 2001-12-27 Akim Demaille <akim@epita.fr>
331
332 * src/print.c, src/print_graph.c (escape): New.
333 Use it to quote the TAGS outputs.
334 * src/print_graph.c (print_state): Now errors are in red, and
335 reductions in green.
336 Prefer high to wide: output the state number on a line of its own.
337
338 2001-12-27 Akim Demaille <akim@epita.fr>
339
340 * src/state.h, src/state.c (reductions_new): New.
341 * src/LR0.c (set_state_table): Let all the states have a
342 `reductions', even if reduced to 0.
343 (save_reductions): Adjust.
344 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
345 * src/print.c (print_reductions, print_actions): Adjust.
346 * src/output.c (action_row): Adjust.
347
348 2001-12-27 Akim Demaille <akim@epita.fr>
349
350 * src/state.h, src/state.c (errs_new, errs_dup): New.
351 * src/LR0.c (set_state_table): Let all the states have an errs,
352 even if reduced to 0.
353 * src/print.c (print_errs, print_reductions): Adjust.
354 * src/output.c (output_actions, action_row): Adjust.
355 * src/conflicts.c (resolve_sr_conflict): Adjust.
356
357 2001-12-27 Akim Demaille <akim@epita.fr>
358
359 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
360
361 2001-12-27 Akim Demaille <akim@epita.fr>
362
363 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
364 * src/print.c: here.
365 (lookaheadset, shiftset): New, used as additional storage by
366 print_reductions.
367 (print_results): Adjust.
368 (print_shifts, print_gotos, print_errs): New, extracted from...
369 (print_actions): here.
370 * src/print_graph.c (print_actions): Remove dead code.
371
372 2001-12-27 Akim Demaille <akim@epita.fr>
373
374 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
375 `$n' and `@n'.
376
377 2001-12-27 Akim Demaille <akim@epita.fr>
378
379 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
380 (build_relations): Adjust.
381
382 2001-12-27 Akim Demaille <akim@epita.fr>
383
384 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
385 duplication.
386
387 2001-12-27 Akim Demaille <akim@epita.fr>
388
389 * src/reader.c (packgram): Catch nitems overflows.
390
391 2001-12-27 Akim Demaille <akim@epita.fr>
392
393 * src/files.c, src/files.h (guard_obstack): Remove.
394 * src/output.c (output): Adjust.
395 * src/reader.c (parse_braces): New, factoring...
396 (copy_action, copy_guard): these two which are renamed as...
397 (parse_action, parse_guard): these.
398 As a voluntary consequence, using braces around guards is now
399 mandatory.
400
401 2001-12-27 Akim Demaille <akim@epita.fr>
402
403 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
404 * src/reader.c (symbol_list): `guard' and `guard_line' are new
405 members.
406 (symbol_list_new): Adjust.
407 (copy_action): action_line is the first line, not the last.
408 (copy_guard): Just as for actions, store the `action' only, not
409 the switch/case/break flesh.
410 Don't parse the user action that might follow the guard, let...
411 (readgram): do it, i.e., now, there can be an action after a
412 guard.
413 In other words the guard is just explicitly optional.
414 (packgram): Adjust.
415 * src/output.c (guards_output): New.
416 (output_parser): Call it when needed.
417 (output): Also free the guard and attrs obstacks.
418 * src/files.c, src/files.h (obstack_save): Remove.
419 (output_files): Remove.
420 As a result, if one needs the former `.act' file, using an
421 appropriate skeleton which requires actions and guards is now
422 required.
423 * src/main.c (main): Adjust.
424 * tests/semantic.at: New.
425 * tests/regression.at: Use `input.y' as input file name.
426 Avoid 8+3 problems by requiring input.c when the test needs the
427 parser.
428
429 2001-12-27 Akim Demaille <akim@epita.fr>
430
431 * src/reader.c (symbol_list_new): Be sure to initialize all the
432 fields.
433
434 2001-12-27 Akim Demaille <akim@epita.fr>
435
436 All the hacks using a final pseudo state are now useless.
437
438 * src/LR0.c (set_state_table): state_table holds exactly nstates.
439 * src/lalr.c (nLA): New.
440 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
441 instead of lookaheadsp from the pseudo state (nstate + 1).
442
443 2001-12-27 Akim Demaille <akim@epita.fr>
444
445 * src/output.c (action_row, token_actions): Use a state_t instead
446 of a integer, and nlookaheads instead of the following state's
447 lookaheadsp.
448
449 2001-12-27 Akim Demaille <akim@epita.fr>
450
451 * src/conflicts.c (log_resolution, flush_shift)
452 (resolve_sr_conflict, set_conflicts, solve_conflicts)
453 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
454 (conflicts_print, print_reductions): Use a state_t instead of an
455 integer when referring to a state.
456 As much as possible, depend upon nlookaheads, instead of the
457 `lookaheadsp' member of the following state (since lookaheads of
458 successive states are successive, the difference between state n + 1
459 and n served as the number of lookaheads for state n).
460 * src/lalr.c (add_lookback_edge): Likewise.
461 * src/print.c (print_core, print_actions, print_state)
462 (print_results): Likewise.
463 * src/print_graph.c (print_core, print_actions, print_state)
464 (print_graph): Likewise.
465 * src/conflicts.h: Adjust.
466
467 2001-12-27 Akim Demaille <akim@epita.fr>
468
469 * src/bison.hairy: Formatting/comment changes.
470 ANSIfy.
471 Remove `register' indications.
472 Add plenty of `static'.
473
474 2001-12-27 Akim Demaille <akim@epita.fr>
475
476 * src/output.c (prepare): Drop the muscle `ntbase' which
477 duplicates ntokens.
478 * src/bison.simple: Formatting/comment changes.
479 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
480 is an undocumented synonym.
481
482 2001-12-22 Akim Demaille <akim@epita.fr>
483
484 * src/output.c (output_table_data): Change the prototype to use
485 `int' for array ranges: some invocations do pass an int, not a
486 short.
487 Reported by Wayne Green.

491 Some actions of web2c.y are improperly triggered.
492 Reported by Mike Castle.
493
494 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
495 * tests/regression.at (Web2c): Rename as...
496 (Web2c Report): this.
497 (Web2c Actions): New.
498
499 2001-12-22 Akim Demaille <akim@epita.fr>
500
501 Reductions in web2c.y are improperly reported.
502 Reported by Mike Castle.
503
504 * src/conflicts.c (print_reductions): Fix.
505 * tests/regression.at (Web2c): New.
506
507 2001-12-18 Akim Demaille <akim@epita.fr>
508
509 Some host fail on `assert (!"foo")', which expands to
510 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
511 Reported by Nelson Beebee.
512
513 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
514 `#define it_succeeded 0' and `assert (it_succeeded)'.
515
516 2001-12-17 Marc Autret <autret_m@epita.fr>
517
518 * src/bison.simple: Don't hard code the skeleton line and filename.
519 * src/output.c (output_parser): Rename 'line' as 'output_line'.
520 New line counter 'skeleton_line' (skeleton-line muscle).
521
522 2001-12-17 Paul Eggert <eggert@twinsun.com>
523
524 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
525 YYDEBUG must be defined to a nonzero value.
526
527 * src/bison.simple (yytname): Do not assume that the user defines
528 YYDEBUG to a properly parenthesized expression.
529
530 2001-12-17 Akim Demaille <akim@epita.fr>
531
532 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
533 nlookaheads is a new member.
534 Adjust all users.
535 * src/lalr.h (nlookaheads): Remove this orphan declaration.
536 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
537 state.
538
539 2001-12-17 Akim Demaille <akim@epita.fr>
540
541 * src/files.h, src/files.c (open_files, close_files): Remove.
542 * src/main.c (main): Don't open/close files, nor invoke lex_free,
543 let...
544 * src/reader.c (reader): Do it.
545
546 2001-12-17 Akim Demaille <akim@epita.fr>
547
548 * src/conflicts.c (print_reductions): Formatting changes.
549
550 2001-12-17 Akim Demaille <akim@epita.fr>
551
552 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
553 (flush_reduce): New.
554 (resolve_sr_conflict): Adjust.
555
556 2001-12-17 Akim Demaille <akim@epita.fr>
557
558 * src/output.c (output_obstack): Be static and rename as...
559 (format_obstack): this, to avoid any confusion with files.c's
560 output_obstack.
561 * src/reader.h (muscle_obstack): Move to...
562 * src/output.h: here, since it's defined in output.c.
563
564 2001-12-17 Akim Demaille <akim@epita.fr>
565
566 * src/output.c (action_row, save_column, default_goto)
567 (sort_actions, matching_state, pack_vector): Better variable
568 locality.
569
570 2001-12-17 Akim Demaille <akim@epita.fr>
571
572 * src/output.c: Various formatting changes.
573
574 2001-12-17 Akim Demaille <akim@epita.fr>
575
576 * src/files.c (output_files): Free the output_obstack.
577 * src/main.c (main): Call print and print_graph conditionally.
578 * src/print.c (print): Work unconditionally.
579 * src/print_graph.c (print_graph): Work unconditionally.
580 * src/conflicts.c (log_resolution): Output only if verbose_flag.
581
582 2001-12-16 Marc Autret <autret_m@epita.fr>
583
584 * src/output.c (actions_output): Fix. When we use %no-lines,
585 there is one less line per action.
586
587 2001-12-16 Marc Autret <autret_m@epita.fr>
588
589 * src/bison.simple: Remove a useless #line directive.
590 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
591 * src/output.c (get_lines_number): New.
592 (output_parser): Adjust, now takes care about the lines of a
593 output muscles.
594 Fix line numbering.
595 (actions_output): Computes the number of lines taken by actions.
596 (output_master_parser): Insert new skeleton which is the name of
597 the output parser file name.
598
599 2001-12-15 Marc Autret <autret_m@epita.fr>
600
601 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
602
603 2001-12-15 Marc Autret <autret_m@epita.fr>
604
605 * src/output.c (output_gram): Keep track of the hairy one.
606
607 2001-12-15 Akim Demaille <akim@epita.fr>
608
609 Make `make distcheck' work.
610
611 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
612 system.h which uses libgettext.h.
613
614 2001-12-15 Akim Demaille <akim@epita.fr>
615
616 * src/nullable.c (set_nullable): Useless rules must be skipped,
617 otherwise, since we range over their symbols, we might look at a
618 nonterminal which no longer ``exists'', i.e., it is not counted in
619 `nvars', hence we overflow our arrays.
620
621 2001-12-15 Akim Demaille <akim@epita.fr>
622
623 The header can also be produced directly, without any obstack!
624 Yahoo!
625
626 * src/files.c, src/files.h (defines_obstack): Remove.
627 (compute_header_macro): Global.
628 (defines_obstack_save): Remove.
629 * src/reader.c (parse_union_decl): No longer output to
630 defines_obstack: its content can be found in the `stype' muscle
631 anyway.
632 (output_token_translations): Merge into...
633 (symbols_output): this.
634 Rename as...
635 (symbols_save): this.
636 (reader): Adjust.
637 * src/output.c (header_output): New.
638 (output): Call it.
639
640 2001-12-15 Akim Demaille <akim@epita.fr>
641
642 * src/reader.c (parse_union_decl): Instead of handling two obstack
643 simultaneously, use one to define the `stype' muscle, and use the
644 value of the latter to fill defines_obstack.
645 (copy_comment): Remove.
646 (copy_comment2): Work for a single obstack.
647 Rename as...
648 (copy_comment): this.
649
650 2001-12-15 Akim Demaille <akim@epita.fr>
651
652 * src/lex.c, src/lex.h (xgetc): No longer static.
653 * src/reader.c (parse_union_decl): Revamp.
654
655 2001-12-15 Akim Demaille <akim@epita.fr>
656
657 Still making progress in separating Bison into (i) input, (ii)
658 process, (iii) output: now we can directly output the parser file
659 without using table_obstack at all.
660
661 * src/files.c, src/files.h (table_obstack): Bye bye.
662 (parser_file_name): New.
663 * src/files.c (compute_output_file_names): Compute it.
664 * src/output.c (actions_output, output_parser)
665 (output_master_parser): To a file instead of an obstack.
666
667 2001-12-15 Akim Demaille <akim@epita.fr>
668
669 Attach actions to rules, instead of pre-outputting them to
670 actions_obstack.
671
672 * src/gram.h (rule_t): action and action_line are new members.
673 * src/reader.c (symbol_list): Likewise.
674 (copy_action): Save the actions within the rule.
675 (packgram): Save them in rule_table.
676 * src/output.c (actions_output): New.
677 (output_parser): Use it on `%%actions'.
678 (output_rule_data): Don't free rule_table.
679 (output): Do it.
680 (prepare): Don't save the `action' muscle.
681 * src/bison.simple: s/%%action/%%actions/.
682
683 2001-12-15 Akim Demaille <akim@epita.fr>
684
685 * src/reader.c (copy_action): When --yacc, don't append a `;'
686 to the user action: let it fail if lacking.
687 Suggested by Arnold Robbins and Tom Tromey.
688
689 2001-12-14 Akim Demaille <akim@epita.fr>
690
691 * src/lex.c (literalchar): Simply return the char you decoded, non
692 longer mess around with obstacks and int pointers.
693 Adjust all callers.
694
695 2001-12-14 Akim Demaille <akim@epita.fr>
696
697 * src/lex.c (literalchar): Don't escape the special characters,
698 just decode them, and keep them as char (before, eol was output as
699 the 2 char string `\n' etc.).
700 * src/output.c (output_rule_data): Use quotearg to output the
701 token strings.
702
703 2001-12-13 Paul Eggert <eggert@twinsun.com>
704
705 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
706 Do not infringe on the global user namespace when using C++.
707 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
708 All uses of `fprintf' and `stderr' changed.
709
710 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
711
712 2001-12-13 Akim Demaille <akim@epita.fr>
713
714 The computation of nullable is broken: it doesn't handle empty
715 RHS's properly.
716
717 * tests/torture.at (GNU AWK Grammar): New.
718 * tests/sets.at (Nullable): New.
719 * src/nullable.c (set_nullable): Instead of blindly looping over
720 `ritems', loop over the rules, and then over their rhs's.
721
722 Work around Autotest bugs.
723
724 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
725 frame, because Autotest understand lines starting with a `+' as
726 traces from the shell. Then, they are not processed properly.
727 Admittedly an Autotest bug, but we don't have time to wait for
728 Autotest to catch up.
729 * tests/regression.at (Broken Closure): Adjust to the new table
730 frames.
731 Move to...
732 * tests/sets.at: here.
733
734 2001-12-13 Akim Demaille <akim@epita.fr>
735
736 * src/closure.c (closure): Use nrules instead of playing tricks
737 with BITS_PER_WORD.
738
739 2001-12-13 Akim Demaille <akim@epita.fr>
740
741 * src/print.c (print_actions): Output the handling of `$' as the
742 traces do: shifting the token EOF. Before EOF was treated as a
743 nonterminal.
744 * tests/regression.at: Adjust some tests.
745 * src/print_graph.c (print_core): Complete the set of items via
746 closure. The next-to-final and final states are still unsatisfying,
747 but that's to be addressed elsewhere.
748 No longer output the rule numbers, but do output the state number.
749 A single loop for the shifts + gotos is enough, but picked a
750 distinct color for each.
751 (print_graph): Initialize and finalize closure.
752
753 2001-12-13 Akim Demaille <akim@epita.fr>
754
755 * src/reader.c (readgram): Remove dead code, an strip useless
756 braces.
757 (get_type): Remove, unused.
758
759 2001-12-12 Akim Demaille <akim@epita.fr>
760
761 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
762 on that of lib/error.c.
763
764 2001-12-12 Akim Demaille <akim@epita.fr>
765
766 Some hosts don't like `/' in includes.
767
768 * src/system.h: Include libgettext.h without qualifying the path.
769 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
770 $(top_srcdir).
771
772 2001-12-11 Marc Autret <autret_m@epita.fr>
773
774 * src/output.c (output_parser): Remove useless muscle.
775
776 2001-12-11 Marc Autret <autret_m@epita.fr>
777
778 * src/bison.simple: Remove #line just before %%epilogue. It
779 is now handled in ...
780 * src/reader.c (read_additionnal_code): Add the output of a
781 #line for the epilogue.
782
783 2001-12-10 Marc Autret <autret_m@epita.fr>
784
785 * src/reader.c (copy_definition): Re-use CPP-outed code which
786 replace precedent remove.
787 * src/bison.simple: Remove #line before %%prologue because
788 %%input-line is wrong at this time.
789
790 2001-12-10 Marc Autret <autret_m@epita.fr>
791
792 * src/reader.c (symbols_output): Clean up.
793 * src/output.c (output_gram, output): Clean up.
794
795 2001-12-10 Akim Demaille <akim@epita.fr>
796
797 * src/lalr.c (initialize_lookaheads): New. Extracted from...
798 * src/LR0.c (set_state_table): here.
799 * src/lalr.c (lalr): Call it.
800
801 2001-12-10 Akim Demaille <akim@epita.fr>
802
803 * src/state.h (shifts): Remove the `number' member: shifts are
804 attached to state, hence no longer need to be labelled with a
805 state number.
806
807 2001-12-10 Akim Demaille <akim@epita.fr>
808
809 Now that states have a complete set of members, the linked list of
810 shifts is useless: just fill directly the state's shifts member.
811
812 * src/state.h (shifts): Remove the `next' member.
813 * src/LR0.c (first_state, last_state): Remove.
814 Adjust the callers.
815 (augment_automaton): Don't look for the shifts that must be added
816 a shift on EOF: it is those of the state we looked for! But now,
817 since shifts are attached, it is no longer needed to looking
818 merely by its id: its number.
819
820 2001-12-10 Akim Demaille <akim@epita.fr>
821
822 * src/LR0.c (augment_automaton): Better variable locality.
823 Remove an impossible branch: if there is a state corresponding to
824 the start symbol being shifted, then there is shift for the start
825 symbol from the initial state.
826
827 2001-12-10 Akim Demaille <akim@epita.fr>
828
829 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
830 only when appropriate: when insert_start_shifting_state' is not
831 invoked.
832 * tests/regression.at (Rule Line Numbers): Adjust.
833
834 2001-12-10 Akim Demaille <akim@epita.fr>
835
836 * src/LR0.c (augment_automaton): Now that all states have shifts,
837 merge the two cases addition shifts to the initial state.
838
839 2001-12-10 Akim Demaille <akim@epita.fr>
840
841 * src/lalr.c (set_state_table): Move to...
842 * src/LR0.c: here.
843 * src/lalr.c (lalr): Don't call it...
844 * src/LR0.c (generate_states): do it.
845 * src/LR0.h (first_state): Remove, only the table is used.
846
847 2001-12-10 Akim Demaille <akim@epita.fr>
848
849 * src/LR0.h (first_shift, first_reduction): Remove.
850 * src/lalr.c: Don't use first_shift: find shifts through the
851 states.
852
853 2001-12-10 Akim Demaille <akim@epita.fr>
854
855 * src/LR0.c: Attach shifts to states as soon as they are
856 computed.
857 * src/lalr.c (set_state_table): Instead of assigning shifts to
858 state, just assert that the mapping was properly done.
859
860 2001-12-10 Akim Demaille <akim@epita.fr>
861
862 * src/LR0.c (insert_start_shift): Rename as...
863 (insert_start_shifting_state): this.
864 (insert_eof_shifting_state, insert_accepting_state): New.
865 (augment_automaton): Adjust.
866 Better locality of the variables.
867 When looking if the start_symbol is shifted from the initial
868 state, using `while (... symbol != start_symbol ...)' sounds
869 better than `while (... symbol < start_symbol ...)': If fail
870 to see how the order between symbols could be relevant!
871
872 2001-12-10 Akim Demaille <akim@epita.fr>
873
874 * src/getargs.h: Don't declare `spec_name_prefix' and
875 `spec_file_prefix', declared by src/files.h.
876 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
877 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
878 * src/output.c (prepare): Adjust.
879 * src/reader.c (symbols_output): Likewise.
880 * src/vmsgetargs.c: Vaguely adjust, but who cares?
881
882 2001-12-10 Akim Demaille <akim@epita.fr>
883
884 * src/muscle_tab.c (muscle_init): NULL is a better default than
885 `"0"'.
886
887 2001-12-10 Akim Demaille <akim@epita.fr>
888
889 * src/reader.c (reader): Calling symbols_output once is enough.
890
891 2001-12-10 Akim Demaille <akim@epita.fr>
892
893 Now that states have a complete set of members, the linked list of
894 reductions is useless: just fill directly the state's reductions
895 member.
896
897 * src/state.h (struct reductions): Remove member `number' and
898 `next'.
899 * src/LR0.c (first_reduction, last_reduction): Remove.
900 (save_reductions): Don't link the new reductions, store them in
901 this_state.
902 * src/lalr.c (set_state_table): No need to attach reductions to
903 states, it's already done.
904 * src/output.c (output_actions): No longer free the shifts, then
905 the reductions, then the states: free all the states and their
906 members.
907
908 2001-12-10 Akim Demaille <akim@epita.fr>
909
910 * src/options.c (OPTN, DRTV, BOTH): New.
911 (option_table): Use them.
912
913 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
914 the job of system.h.
915 * src/options.c: Don't include stdio.h and xalloc.h for the same
916 reasons.
917
918 2001-12-10 Akim Demaille <akim@epita.fr>
919
920 * src/output.c (output, prepare): Make sure the values of the
921 muscles `action' and `prologue' are 0-terminated.
922
923 2001-12-10 Akim Demaille <akim@epita.fr>
924
925 Clean up GCC warnings.
926
927 * src/reader.c (copy_action): `buf' is not used.
928 (parse_skel_decl): Be static.
929 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
930 * src/options.h (create_long_option_table): Have a real prototype.
931 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
932 (hash_delete_at): Return const void *.
933 Adjust casts to preserve the const.
934
935 2001-12-10 Akim Demaille <akim@epita.fr>
936
937 * configure.in: Require 2.52g.
938 M4 is not needed, but AUTOM4TE is.
939 * m4/m4.m4: Remove.
940 * tests/Makefile.am: Adjust.
941
942 2001-12-10 Akim Demaille <akim@epita.fr>
943
944 One structure for states is enough, even though theoretically
945 there are LR(0) states and LALR(1) states.
946
947 * src/lalr.h (state_t): Remove.
948 (state_table): Be state_t **, not state_t *.
949 * src/state.h (core, CORE_ALLOC): Rename as...
950 (state_t, STATE_ALLOC): this.
951 Add the LALR(1) members: shifts, reductions, errs.
952 * src/LR0.c (state_table): Rename as...
953 (state_hash): this, to avoid name clashes with the global
954 `state_table'.
955 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
956 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
957
958 2001-12-10 Akim Demaille <akim@epita.fr>
959
960 Bison dumps core on bash.y.
961 Reported by Pascal Bart.
962
963 * src/warshall.c (bitmatrix_print): New.
964 (TC): Use it.
965 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
966 j must be the outer loop.
967 * tests/regression.at (Broken Closure): New.
968
969 2001-12-05 Akim Demaille <akim@epita.fr>
970
971 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
972 its argument.

974
975 2001-12-05 Akim Demaille <akim@epita.fr>
976
977 * src/conflicts.c (err_table): Remove.
978 (resolve_sr_conflict): Adjust.
979 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
980 Rename as...
981 (state_t.reductions, state_t.shifts): this.
982
983 2001-12-05 Akim Demaille <akim@epita.fr>
984
985 * src/reduce.c (reduce_grammar_tables): No longer disable the
986 removal of useless rules via CPP but via `if (0)', so that the
987 compiler still check the code is valid.
988 For instance, it should have noticed `rline' no longer exists: use
989 the `line' member of rule_t.
990 * src/gram.c (dummy, rline): Remove, unused.
991
992 2001-12-05 Akim Demaille <akim@epita.fr>
993
994 * src/output.c (pack_vector): Use assert, not berror.
995 * src/main.c (berror): Remove, unused.
996
997 2001-12-05 Akim Demaille <akim@epita.fr>
998
999 New experimental feature: if --verbose --trace output all the
1000 items of a state, not only its kernel.
1001
1002 * src/print.c (print_core): If `trace_flag', then invoke closure
1003 before outputting the items of the state (print_core is no longer
1004 a correct name them).
1005 (print_results): Invoke new_closure/free_closure if needed.
1006
1007 2001-12-05 Akim Demaille <akim@epita.fr>
1008
1009 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1010 * src/closure.c, src/closure.h (itemsetsize): Rename as...
1011 (nitemset): for consistency with the rest of the project.
1012
1013 2001-12-05 Akim Demaille <akim@epita.fr>
1014
1015 * src/closure.c (print_closure): Improve.
1016 (closure): Use it for printing input and output.
1017
1018 2001-12-05 Akim Demaille <akim@epita.fr>
1019
1020 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1021 indexed by nonterminals.
1022
1023 2001-12-05 Akim Demaille <akim@epita.fr>
1024
1025 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1026 what it was!).
1027 * src/warshall.h: Remove accidental duplication of the content.
1028
1029 2001-12-05 Akim Demaille <akim@epita.fr>
1030
1031 * src/closure.c (set_fderives): De-obfuscate.
1032
1033 2001-12-05 Akim Demaille <akim@epita.fr>
1034
1035 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
1036
1037 2001-12-05 Akim Demaille <akim@epita.fr>
1038
1039 * src/closure.c (set_firsts): De-obfuscate.
1040
1041 2001-12-05 Akim Demaille <akim@epita.fr>
1042
1043 * src/output.c (action_row): De-obfuscate
1044 using the good o' techniques: arrays not pointers, variable
1045 locality, BITISSET, RESETBIT etc.
1046
1047 2001-12-05 Akim Demaille <akim@epita.fr>
1048
1049 Pessimize the code to simplify it: from now on, all the states
1050 have a valid SHIFTS, which NSHIFTS is possibly 0.
1051
1052 * src/LR0.c (shifts_new): Be global and move to..
1053 * src/state.c, src/state.h: here.
1054 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1055 * src/print_graph: Adjust.
1056
1057 2001-12-05 Akim Demaille <akim@epita.fr>
1058
1059 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1060 * src/conflicts.c: Use it.
1061 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1062 incorrectly ``simplified''.
1063
1064 2001-12-05 Akim Demaille <akim@epita.fr>
1065
1066 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1067 using the good o' techniques: arrays not pointers, variable
1068 locality, BITISSET, RESETBIT etc.
1069
1070 2001-12-05 Akim Demaille <akim@epita.fr>
1071
1072 * src/state.h (SHIFT_SYMBOL): New.
1073 * src/conflicts.c: Use it to deobfuscate.
1074

1076
1077 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1078 (print_reductions): De-obfuscate using the good o' techniques:
1079 arrays not pointers, variable locality, BITISSET.
1080
1081 2001-12-05 Akim Demaille <akim@epita.fr>
1082
1083 * src/conflicts.c (print_reductions): Arrays, not pointers.
1084 Use BITISSET.
1085
1086 2001-12-05 Akim Demaille <akim@epita.fr>
1087
1088 * src/conflicts.c (print_reductions): Pessimize, but clarify.
1089
1090 2001-12-05 Akim Demaille <akim@epita.fr>
1091
1092 * src/conflicts.c (print_reductions): Improve variable locality.
1093
1094 2001-12-05 Akim Demaille <akim@epita.fr>
1095
1096 * src/conflicts.c (print_reductions): Pessimize, but clarify.
1097
1098 2001-12-05 Akim Demaille <akim@epita.fr>
1099
1100 * src/conflicts.c (print_reductions): Improve variable locality.
1101
1102 2001-12-05 Akim Demaille <akim@epita.fr>
1103
1104 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1105 * src/lalr.c: Use them.
1106
1107 2001-12-05 Akim Demaille <akim@epita.fr>
1108
1109 * src/LR0.c (augment_automaton): Formatting changes.
1110 Better variable locality.
1111
1112 2001-12-05 Akim Demaille <akim@epita.fr>
1113
1114 * src/lalr.c (matrix_print): New.
1115 (transpose): Use it.
1116 Use arrays instead of pointers.
1117
1118 2001-12-05 Akim Demaille <akim@epita.fr>
1119
1120 * src/lalr.c (maxrhs): Move to...
1121 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1122 * src/lalr.c (build_relations): Adjust.
1123
1124 2001-12-05 Akim Demaille <akim@epita.fr>
1125
1126 * src/lalr.c (transpose): Free the memory allocated to the
1127 argument, as it is replaced by the results by the unique caller.
1128 (build_relations): Merely invoke transpose: it handles the memory
1129 deallocation.
1130 Improve variable locality.
1131 Avoid variables used as mere abbreviations.
1132 (compute_lookaheads): Use arrays instead of pointers.
1133
1134 2001-12-05 Akim Demaille <akim@epita.fr>
1135
1136 * src/lalr.c (initialize_F): Improve variable locality.
1137 Avoid variables used as mere abbreviations.
1138
1139 2001-12-05 Akim Demaille <akim@epita.fr>
1140
1141 * src/derives.c (print_derives): Display the ruleno.
1142 * src/lalr.c (initialize_F, transpose): Better variable locality
1143 to improve readability.
1144 Avoid variables used as mere abbreviations.
1145
1146 2001-12-05 Akim Demaille <akim@epita.fr>
1147
1148 * src/lalr.c (traverse): Use arrays instead of pointers.
1149
1150 2001-12-05 Akim Demaille <akim@epita.fr>
1151
1152 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1153 the handling of squeue.
1154 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1155
1156 2001-12-05 Akim Demaille <akim@epita.fr>
1157
1158 Because useless nonterminals are now kept alive (instead of being
1159 `destroyed'), we now sometimes examine them, and store information
1160 related to them. Hence we need to know their number, and adjust
1161 memory allocations.
1162
1163 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1164 static.
1165 * src/LR0.c (allocate_itemsets): The memory allocated to
1166 `symbol_count' was used for two different purpose: once to count
1167 the number of occurrences of each symbol, and later reassigned to
1168 `shift_symbol', containing the symbol that can be shifted from a
1169 given state.
1170 Deobfuscate, i.e., allocate, use and free `symbol_count' here
1171 only, and...
1172 (new_itemsets): Allocate `shift_symbol' here.
1173 (allocate_itemsets): symbol_count includes useless nonterminals.
1174 Make room for them.
1175 (free_storage): Use `free', not `XFREE', for pointers that cannot
1176 be null.
1177
1178 2001-12-05 Akim Demaille <akim@epita.fr>
1179
1180 * src/nullable.c (set_nullable): Deobfuscate the handling of
1181 ritem.
1182 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1183
1184 2001-12-05 Akim Demaille <akim@epita.fr>
1185
1186 * src/gram.c, src/gram.h (ritem_print): New.
1187 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1188 (This useless function was defined only to work around VMS linkers
1189 that can't handle compilation units with variables only).
1190 * src/reduce.c (dump_grammar): Use it to trace the construction of
1191 ritem.
1192
1193 2001-12-04 Paul Eggert <eggert@twinsun.com>
1194
1195 * src/bison.simple (union yyalloc): Change member names
1196 to be the same as the stack names.
1197 (yyparse): yyptr is now union yyalloc *, not char *.
1198 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
1199 and may generate better code on some machines.
1200 (yystpcpy): Use prototype if __STDC__ is defined, not just
1201 if __cplusplus is defined.
1202
1203 2001-11-30 Akim Demaille <akim@epita.fr>
1204
1205 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1206 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1207 Gettext doesn't compile cleanly, and dies with -Werror.
1208 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1209 Include WARNING_CFLAGS here.
1210 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1211 before being defined.
1212
1213 2001-11-27 Paul Eggert <eggert@twinsun.com>
1214
1215 * lib/quotearg.h (quotearg_n, quotearg_n_style):
1216 First arg is int, not unsigned.
1217 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1218 (SIZE_MAX, UINT_MAX): New macros.
1219 (quotearg_n_options): Abort if N is negative.
1220 Avoid overflow check on hosts where size_t is 64 bits and int
1221 is 32 bits, as overflow is impossible there.
1222 Fix off-by-one typo that caused unnecessary reallocation.
1223
1224 2001-11-29 Paul Eggert <eggert@twinsun.com>
1225
1226 Name space cleanup in generated parser.
1227
1228 * doc/bison.texinfo (Bison Parser): Discuss system headers
1229 and their effect on the user name space.
1230
1231 * src/bison.simple:
1232 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1233 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1234 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1235
1236 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
1237 on user names when possible.
1238
1239 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1240 Simplify test for whather <alloca.h> exists.
1241
1242 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1243
1244 (<stdio.h>): Include if YYDEBUG.
1245
1246 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
1247 ! defined (yyoverflow) && ! defined (yymemcpy).
1248
1249 (yymemcpy, yyparse): Rename local variables as needed so that
1250 they all begin with 'yy'.
1251
1252 (yystrlen, yystpcpy): New functions.
1253
1254 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1255 All uses changed.
1256
1257 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
1258 instead of relying on string.h functions. Use YYSTACK_ALLOC
1259 and YYSTACK_FREE instead of malloc and free.
1260
1261 2001-11-30 Akim Demaille <akim@epita.fr>
1262
1263 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

1268
1269 * tests/reduce.at (Useless Nonterminals): Fix.
1270
1271 2001-11-30 Akim Demaille <akim@epita.fr>
1272
1273 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1274 if body instead of `;' to pacify GCC's warnings.
1275
1276 2001-11-30 Akim Demaille <akim@epita.fr>
1277
1278 Instead of mapping the LHS of unused rules to -1, keep the LHS
1279 valid, but flag the rules as invalid.
1280
1281 * src/gram.h (rule_t): `useful' is a new member.
1282 * src/print.c (print_grammar): Adjust.
1283 * src/derives.c (set_derives): Likewise.
1284 * src/reader.c (packgram, reduce_output): Likewise.
1285 * src/reduce.c (reduce_grammar_tables): Likewise.
1286 * tests/reduce.at (Underivable Rules, Useless Rules): New.
1287
1288 2001-11-30 Akim Demaille <akim@epita.fr>
1289
1290 * src/reduce.c (reduce_output): Formatting changes.
1291 * src/print.c (print_results, print_grammar): Likewise.
1292 * tests/regression.at (Rule Line Numbers)
1293 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
1294
1295 2001-11-30 Akim Demaille <akim@epita.fr>
1296
1297 * src/reduce.c (nonterminals_reduce): Instead of throwing away
1298 useless nonterminals, move them at the end of the symbol arrays.
1299 (reduce_output): Adjust.
1300 * tests/reduce.at (Useless Nonterminals): Adjust.
1301
1302 2001-11-30 Akim Demaille <akim@epita.fr>
1303
1304 * src/reduce.c: Various comment/formatting changes.
1305 (nonterminals_reduce): New, extracted from...
1306 (reduce_grammar_tables): here.
1307 (reduce_grammar): Call nonterminals_reduce.
1308
1309 2001-11-29 Paul Eggert <eggert@twinsun.com>
1310
1311 * src/bison.simple (YYSTACK_REALLOC): Remove.
1312 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1313 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1314 New macros.
1315 (union yyalloc): New type.
1316 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1317 an arbitrary restriction on hosts where size_t is wider than int.
1318
1319 (yyparse): Don't dump core if alloca or malloc fails; instead, report
1320 a parser stack overflow. Allocate just one block of memory for all
1321 three stacks, instead of allocating three blocks; this typically is
1322 faster and reduces fragmentation.
1323
1324 Do not limit the number of items in the stack to a value that fits
1325 in 'int', as this is an arbitrary limit on hosts with 64-bit
1326 size_t and 32-bit int.
1327
1328 2001-11-29 Marc Autret <autret_m@epita.fr>
1329
1330 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
1331 of defining YYERROR_VERBOSE.
1332 [AT_DATA]: $4 is now out of C declarations in the prologue.
1333
1334 2001-11-28 Marc Autret <autret_m@epita.fr>
1335
1336 * src/reader.c (parse_dquoted_param): New.

1340
1341 2001-11-28 Marc Autret <autret_m@epita.fr>
1342
1343 * src/output.h: And put its extern declaration here.

1350 percent option.
1351 Include output.h.
1352

1354 (parse_include_decl): Remove.
1355 * src/lex.h (token_t): Remove tok_include.

1367
1368 * src/bison.simple: Fix debug.
1369 [YYERROR_VERBOSE]: Re-integrate as an internal macro.
1370
1371 2001-11-28 Akim Demaille <akim@epita.fr>
1372
1373 * src/LR0.c (shifts_new): New.
1374 (save_shifts, insert_start_shift, augment_automaton): Use it.
1375
1376 2001-11-28 Akim Demaille <akim@epita.fr>
1377
1378 * src/closure.c (closure): `b' and `ruleno' denote the same value:
1379 keep ruleno only.
1380
1381 2001-11-28 Akim Demaille <akim@epita.fr>
1382
1383 * src/closure.c (closure): Instead of looping over word in array
1384 then bits in words, loop over bits in array.
1385
1386 2001-11-28 Akim Demaille <akim@epita.fr>
1387
1388 * src/closure.c (closure): No longer optimize the special case
1389 where all the bits of `ruleset[r]' are set to 0, to make the code
1390 clearer.
1391
1392 2001-11-28 Akim Demaille <akim@epita.fr>
1393
1394 * src/closure.c (closure): `r' and `c' are new variables, used to
1395 de-obfuscate accesses to RULESET and CORE.
1396
1397 2001-11-28 Akim Demaille <akim@epita.fr>
1398
1399 * src/reduce.c (reduce_print): Use ngettext.
1400 (dump_grammar): Improve the trace accuracy.
1401
1402 2001-11-28 Akim Demaille <akim@epita.fr>
1403
1404 * src/reduce.c (dump_grammar): Don't translate trace messages.
1405
1406 2001-11-28 Akim Demaille <akim@epita.fr>
1407
1408 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
1409 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
1410 as all tags are free'ed afterwards.

1414
1415 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

1758 use abs. path to find config.h.
1759 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

3161
3162 * src/lex.h: Rename all the tokens:

3184 * src/reader.c (read_declarations): Adjust.
3185 * src/files.c (open_files): Don't call `compute_base_names', don't
3186 compute `attrsfile' since they depend upon data which might be
3187 *in* the input file now.
3188 (output_files): Do it here.
3189 * src/output.c (output_headers): Document the fact that this patch
3190 introduces a guaranteed SEGV for semantic parsers.
3191 * doc/bison.texinfo: Document them.

3217 2000-12-20 Akim Demaille <akim@epita.fr>
3218
3219 * src/files.c (open_files): Actually the `.output' file is based
3220 on the short_base_name, not base_name.

3222
3223 2000-12-20 Akim Demaille <akim@epita.fr>

3247
3248 * src/files.c (strsuffix): New.
3249 (stringappend): Be just like strcat but allocate.
3250 (base_names): Eve out from open_files.
3251 Try to simplify the rather hairy computation of base_name and
3252 short_base_name.
3253 (open_files): Use it.

3255

3271
3272 2000-12-19 Akim Demaille <akim@epita.fr>
3273
3274 Let the handling of the skeleton files be local to the procedures
3275 that use it.

3278 longer static.
3279 (fparser, open_extra_files): Remove.
3280 (open_files, output_files): Don't take care of fparser.
3281 * src/files.h: Adjust.
3282 * src/output.c (output_parser): Open and close the file to the
3283 skeleton.
3284 * src/reader.c (read_declarations): When %semantic_parser, open

3290 * src/system.h (BISON_SIMPLE, BISON_HAIRY): ... to here.
3291
3292 2000-12-19 Akim Demaille <akim@epita.fr>
3293
3294 * src/files.c (open_files): Yipee! We no longer need all the code
3295 looking for `/tmp' since we have no tmp file.
3296
3297 2000-12-19 Akim Demaille <akim@epita.fr>
3298
3299 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3325
3326 * lib/obstack.h: Formatting changes.
3327 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3328 prevents type checking.
3329 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3330 cast the value to (void *): assigning a `foo *' to a `void *'
3331 variable is valid.
3332 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3333 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3348 2000-11-17 Akim Demaille <akim@epita.fr>
3349
3350 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
3351 macros.

3376 * src/output.c (output): Remove useless variables.
3377 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3378 argument `data' for consistency with the prototypes.
3379 Qualify it `const'.
3380 (obstack_copy, obstack_copy0): Rename the second argument as
3381 `address' for consistency. Qualify it `const'.
3382 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
3383 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
3384 `const' their input argument (`data' or `address').
3385 Adjust the corresponding macros to include `const' in casts.

3395 For some reason, this was not applied.
3396
3397 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3408
3409 * src/files.c (obstack_save): New function.
3410 (done): Rename as...
3411 (output_files): this.
3412 Use `obstack_save'.
3413 * src/main.c (main): Don't use `atexit' to register `done', since
3414 it no longer has to remove tmp files, just call `output_files'
3415 when there are no errors.
3416
3417 2000-11-02 Akim Demaille <akim@epita.fr>
3418

3426
3427 * src/files.c (fdefines, ftable): Removed.
3428 (defines_ostack, table_obstack): New.

3438
3439 Change each use of `fattrs' into a use of `attrs_obstack'.
3440

3477
3478 2000-10-16 Akim Demaille <akim@epita.fr>
3479
3480 * src/lex.c (read_typename): New function.
3481 (lex): Use it.
3482 * src/reader.c (copy_dollar): Likewise.
3483
3484 2000-10-16 Akim Demaille <akim@epita.fr>
3485
3486 * src/reader.c (copy_comment2): Expect the input stream to be on
3487 the `/' which is suspected to open a comment, instead of being
3488 called after `//' or `/*' was read.
3489 (copy_comment, copy_definition, parse_union_decl, copy_action)
3490 (copy_guard): Adjust.
3491
3492 2000-10-16 Akim Demaille <akim@epita.fr>
3493
3494 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

3498
3499 * src/reader.c (copy_dollar): New function.

3509
3510 2000-10-04 Akim Demaille <akim@epita.fr>
3511
3512 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
3513
3514 2000-10-04 Akim Demaille <akim@epita.fr>
3515
3516 * doc/bison.texinfo: Various typos spotted by Neil Booth.
3517
3518 2000-10-04 Akim Demaille <akim@epita.fr>
3519
3520 When a literal string is used to define two different tokens,
3521 `bison -v' segfaults.
3522 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3523
3524 * tests/regression.m4: New file.
3525 Include the core of the sample provided by Piotr Gackiewicz.

3527 properly.
3528
3529 2000-10-04 Akim Demaille <akim@epita.fr>
3530
3531 * src/reader.c (parse_expect_decl): Keep `count' within the size
3532 of `buffer'.
3533 From Neil Booth.
3534
3535 2000-10-02 Paul Eggert <eggert@twinsun.com>
3536
3537 * bison.s1 (yyparse): Assign the default value
3538 unconditionally, to avoid a GCC warning and make the parser a
3539 tad smaller.
3540
3541 2000-10-02 Akim Demaille <akim@epita.fr>
3542
3543 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3544 options.
3545
3546 2000-10-02 Akim Demaille <akim@epita.fr>
3547
3548 * src/derives.c, src/print.c, src/reduce.c: To ease the
3549 translation, move some `\n' out of the translated strings.
3550
3551 2000-10-02 Akim Demaille <akim@epita.fr>
3552
3553 The location tracking mechanism is precious for parse error
3554 messages. Nevertheless, it is enabled only when `@n' is used in
3555 the grammar, which is a different issue (you can use it in error
3556 message, but not in the grammar per se). Therefore, there should
3557 be another means to enable it.
3558
3559 * src/getargs.c (getargs): Support `--locations'.
3560 (usage): Report it.
3561 * src/getargs.h (locationsflag): Export it.
3562 * src/lex.c (percent_table): Support `%locations'.
3563 * src/reader.c (yylsp_needed): Remove this variable, now replaced
3564 with `locationsflag'.
3565 * doc/bison.texinfo: Document `--locations' and `%locations'.
3566 Sort the options.
3567 * tests/calc.m4: Test it.
3568
3569 For regularity of the names, replace each
3570 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3571 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3572 In addition replace each `flag' with `_flag'.
3573
3574 2000-10-02 Akim Demaille <akim@epita.fr>
3575
3576 Also test parse error messages, including with YYERROR_VERBOSE.
3577
3578 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3579 associative).
3580 Use it to check the computations.
3581 Use it to check `nonassoc' is honored.
3582 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3583 `--yyerror-verbose'.
3584 (_AT_CHECK_CALC): Adjust to this option.
3585 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3586
3587 2000-10-02 Akim Demaille <akim@epita.fr>
3588
3589 Test also `--verbose', `--defines' and `--name-prefix'. Testing
3590 the latter demonstrates a flaw in the handling of non debugging
3591 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3592 was used in order to simplify:
3593
3594 #if YYDEBUG
3595 if (yydebug)
3596 {
3597 ...
3598 }
3599 #endif
3600
3601 into
3602
3603 if (yydebug)
3604 {
3605 ...
3606 }
3607
3608 unfortunately this leads to a CPP conflict when
3609 `--name-prefix=foo' is used since it produces `#define yydebug
3610 foodebug'.
3611
3612 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3613 (YYDPRINTF): New macro.
3614 Spread its use.
3615 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3616 the bison options.
3617 Also test `--verbose', `--defines' and `--name-prefix'.
3618
3619 2000-10-02 Akim Demaille <akim@epita.fr>
3620
3621 Improve the readability of the produced parsers.
3622
3623 * src/bison.s1: Formatting changes.
3624 Improve the comment related to the `$' mark.
3625 (yydefault): Don't fall through to `yyresume': `goto' there.
3626 * src/output.c (output_parser): When the `$' is met, skip the end
3627 of its line.
3628 New variable, `number_of_dollar_signs', to check there's exactly
3629 one `$' in the parser skeleton.
3630
3631 2000-10-02 Akim Demaille <akim@epita.fr>
3632
3633 * lib/xstrdup.c: New file, from the fileutils.
3634 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3635 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3636 instead of strlen + xmalloc + strcpy.
3637 * src/symtab.c (copys): Remove, use xstrdup instead.
3638
3639 2000-10-02 Akim Demaille <akim@epita.fr>
3640
3641 * src/gram.h (associativity): New enum type which replaces the
3642 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3643 `right_assoc', `left_assoc' and `non_assoc'.
3644 Adjust all dependencies.
3645 * src/reader.c: Formatting changes.
3646 (LTYPESTR): Don't define it, use it as a literal in
3647 `reader_output_yylsp'.
3648 * src/symtab.h (symbol_class): New enum type which replaces the
3649 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3650 `sunknown', `stoken and `snterm'.
3651
3652 2000-10-02 Akim Demaille <akim@epita.fr>
3653
3654 * src/getargs.c (fixed_outfiles): Rename as...
3655 (yaccflag): for consistency and accuracy.
3656 Adjust dependencies.
3657
3658 2000-10-02 Akim Demaille <akim@epita.fr>
3659
3660 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3661 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
3662 difficult and introduced a lot of core dump. It turns out that
3663 Bison used an implementation of `xmalloc' based on `calloc', and
3664 at various places it does depend upon the initialization to 0. I
3665 have not tried to isolate the pertinent places, and all the former
3666 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
3667 someone should address this issue.
3668
3669 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3670 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
3671 files.

3677
3678 Various anti-`extern in *.c' changes.
3679
3680 * src/system.h: Include `assert.h'.
3681
3682 2000-10-02 Akim Demaille <akim@epita.fr>
3683
3684 * src/state.h (nstates, final_state, first_state, first_shift)
3685 (first_reduction): Move their exportation from here...
3686 * src/LR0.h: to here.
3687 Adjust dependencies.
3688 * src/getargs.c (statisticsflag): New variable.
3689 Add support for `--statistics'.
3690 Adjust dependencies.
3691

3705 (print_results): this new function.
3706 Adjust dependencies.
3707
3708 2000-10-02 Akim Demaille <akim@epita.fr>
3709
3710 * src/conflicts.c (conflict_report): New function.
3711 (conflict_log, verbose_conflict_log): Replace with...
3712 (print_conflicts): this function.
3713 Adjust dependencies.
3714 * src/conflicts.h: New file.
3715 Propagate its inclusion.
3716
3717 2000-10-02 Akim Demaille <akim@epita.fr>
3718
3719 * src/nullable.h: New file.
3720 Propagate its inclusion.

3722
3723 2000-10-02 Akim Demaille <akim@epita.fr>
3724

3726 Propagate its inclusion.
3727 * src/reduce.c: Topological sort and other formatting changes.
3728 (bool, TRUE, FALSE): Move their definition to...

3732
3733 * src/files.c: Formatting changes.

3769
3770 `user_toknums' is output as a `short[]' in `output.c', while it is
3771 defined as a `int[]' in `reader.c'. For consistency with the
3772 other output tables, `user_toknums' is now defined as a table of
3773 shorts.

3814 inclusion.
3815 Don't define PARAMS.
3816 * src/system.h: Define PARAMS.
3817 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3818 purpose of config.h. system.h must not try to fix wrong
3819 definitions in config.h.
3820
3821 2000-09-20 Akim Demaille <akim@epita.fr>
3822

3955 * Makefile.am (SUBDIRS): Adjust.

3984
3985 On syntax errors, report the token on which we choked.

4035 2000-03-17 Akim Demaille <akim@epita.fr>
4036
4037 Change the handling of @s so that they behave exactly like $s.
4038 There is now a pseudo variable @$ (readble and writable), location
4039 of the lhs of the rule (by default ranging from the location of
4040 the first symbol of the rhs, to the location of the last symbol,
4041 or, if the rhs is empty, YYLLOC).

4074
4075 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
4076 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4077 One `#if YYDEBUG' remains, since it uses variables which are

4081

4118 * m4/Makefile.am (EXTRA_DIST): New variable.
4119 * m4/gettext.m4: New file, from the fileutils.

4735 1995-10-15 Richard Stallman <rms@gnu.org>
4736
4737 * src/vmsgetargs.c, src/getargs.c:
4738 Added -n, -k, and -raw switches.
4739 (noparserflag, toknumflag, rawtoknumflag): New variables.
4740

4748
4749 * src/reader.c (reader_output_yylsp):
4750 New function.
4751 (readgram): Use `#if 0' around code that accepted %command
4752 inside grammar rules: The documentation doesn't allow it,
4753 and it will fail since the %command processors scan for the next %.
4754 (parse_token_decl): Extended the %token
4755 declaration to allow a multi-character symbol as an alias.
4756 (parse_thong_decl): New function.
4757 (read_declarations): Added %thong declarations.
4758 (read_declarations): Handle NOOP to deal with allowing
4759 % declarations as another means to specify the flags.
4760 (readgram): Allow %prec prior to semantics embedded in a rule.
4761 (skip_to_char, read_declarations, copy_definition)
4762 (parse_token_decl, parse_start_decl, parse_type_decl)
4763 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
4764 (get_type_name, copy_guard, copy_action, readgram)
4765 (get_type, packsymbols): Revised most error messages.
4766 Changed `fatal' to `warnxxx' to avoid aborting for error.
4767 Revised and use multiple warnxxx functions to avoid using VARARGS1.
4768 (read_declarations): Improve the error message for
4769 an invalid character. Do not abort.
4770 (read_declarations, copy_guard, copy_action): Use
4771 printable_version to avoid unprintable characters in printed output.
4772 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
4773 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
4774 Allow the type of a non-terminal can be given
4775 more than once, as long as all specifications give the same type.
4776
4777 * src/output.c:
4778 (output_headers, output_trailers, output, output_gram)
4779 (output_rule_data): Implement noparserflag variable.
4780 Implement toknumflag variable.
4781 (output): Call reader_output_yylsp to output LTYPESTR.
4782
4783 * src/main.c (main):
4784 If reader sees an error, don't process the grammar.
4785 (fatals): Updated to not use VARARGS1.
4786 (printable_version, int_to_string, warn, warni, warns, warnss)
4787 (warnsss): New error reporting functions. Avoid abort for error.
4788
4789 * src/lex.h:
4790 Added THONG and NOOP for alias processing.
4791 Added SETOPT for the new code that allows setting options with %flags.
4792
4793 * src/lex.c:
4794 Include getopt.h. Add some extern decls.
4795 (safegetc): New function to deal with EOF gracefully.
4796 (literalchar); new function to deal with reading \ escapes.
4797 (lex): Use literalchar.
4798 (lex): Implemented "..." tokens.
4799 (literalchar, lex, parse_percent_token): Made tokenbuffer
4800 always contain the token. This includes growing the token
4801 buffer while reading an integer.
4802 (parse_percent_token): Replaced if-else statement with percent_table.
4803 (parse_percent_token): Added % declarations as another
4804 way to specify the flags -n, -l, and -r. Also added hooks for
4805 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4806 major changes to files.c.
4807 (lex) Retain in the incoming stream a character following
4808 an incorrect '/'.
4809 (skip_white_space, lex): Revised most error messages
4810 and changed fatal to warn to avoid aborting.
4811 (percent_table): Added %thong declarations.
4812
4813 * src/gram.h: Comment changes.
4814
4815 * src/files.c (openfiles, open_extra_files, done):
4816 Add faction flag
4817 and actfile file. Handle noparserflag. Both for -n switch.
4818
