[bison.git] / ChangeLog
1 2001-12-15 Akim Demaille <akim@epita.fr>
2
3 * src/lex.c, src/lex.h (xgetc): No longer static.
4 * src/reader.c (parse_union_decl): Revamp.
5
6 2001-12-15 Akim Demaille <akim@epita.fr>
7
8 Still making progress in separating Bison into (i) input, (ii)
9 process, (iii) output: now we can directly output the parser file
10 without using table_obstack at all.
11
12 * src/files.c, src/files.h (table_obstack): Bye bye.
13 (parser_file_name): New.
14 * src/files.c (compute_output_file_names): Compute it.
15 * src/output.c (actions_output, output_parser)
16 (output_master_parser): To a file instead of an obstack.
17
18 2001-12-15 Akim Demaille <akim@epita.fr>
19
20 Attach actions to rules, instead of pre-outputting them to
21 actions_obstack.
22
23 * src/gram.h (rule_t): action and action_line are new members.
24 * src/reader.c (symbol_list): Likewise.
25 (copy_action): Save the actions within the rule.
26 (packgram): Save them in rule_table.
27 * src/output.c (actions_output): New.
28 (output_parser): Use it on `%%actions'.
29 (output_rule_data): Don't free rule_table.
30 (output): Do it.
31 (prepare): Don't save the `action' muscle.
32 * src/bison.simple: s/%%action/%%actions/.
33
34 2001-12-15 Akim Demaille <akim@epita.fr>
35
36 * src/reader.c (copy_action): When --yacc, don't append a `;'
37 to the user action: let it fail if lacking.
38 Suggested by Aharon Robbins and Tom Tromey.
39
40 2001-12-14 Akim Demaille <akim@epita.fr>
41
42 * src/lex.c (literalchar): Simply return the char you decoded, non
43 longer mess around with obstacks and int pointers.
44 Adjust all callers.
45
46 2001-12-14 Akim Demaille <akim@epita.fr>
47
48 * src/lex.c (literalchar): Don't escape the special characters,
49 just decode them, and keep them as char (before, eol was output as
50 the 2 char string `\n' etc.).
51 * src/output.c (output_rule_data): Use quotearg to output the
52 token strings.
53
54 2001-12-13 Paul Eggert <eggert@twinsun.com>
55
56 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
57 Do not infringe on the global user namespace when using C++.
58 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
59 All uses of `fprintf' and `stderr' changed.
60
61 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
62
63 2001-12-13 Akim Demaille <akim@epita.fr>
64
65 The computation of nullable is broken: it doesn't handle empty
66 RHS's properly.
67
68 * tests/torture.at (GNU AWK Grammar): New.
69 * tests/sets.at (Nullable): New.
70 * src/nullable.c (set_nullable): Instead of blindly looping over
71 `ritems', loop over the rules, and then over their rhs's.
72
73 Work around Autotest bugs.
74
75 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
76 frame, because Autotest understand lines starting with a `+' as
77 traces from the shell. Then, they are not processed properly.
78 Admittedly an Autotest bug, but we don't have time to wait for
79 Autotest to catch up.
80 * tests/regression.at (Broken Closure): Adjust to the new table
81 frames.
82 Move to...
83 * tests/sets.at: here.
84
85 2001-12-13 Akim Demaille <akim@epita.fr>
86
87 * src/closure.c (closure): Use nrules instead of playing tricks
88 with BITS_PER_WORD.
89
90 2001-12-13 Akim Demaille <akim@epita.fr>
91
92 * src/print.c (print_actions): Output the handling of `$' as the
93 traces do: shifting the token EOF. Before EOF was treated as a
94 nonterminal.
95 * tests/regression.at: Adjust some tests.
96 * src/print_graph.c (print_core): Complete the set of items via
97 closure. The next-to-final and final states are still unsatisfying,
98 but that's to be addressed elsewhere.
99 No longer output the rule numbers, but do output the state number.
100 A single loop for the shifts + gotos is enough, but picked a
101 distinct color for each.
102 (print_graph): Initialize and finalize closure.
103
104 2001-12-13 Akim Demaille <akim@epita.fr>
105
106 * src/reader.c (readgram): Remove dead code, an strip useless
107 braces.
108 (get_type): Remove, unused.
109
110 2001-12-12 Akim Demaille <akim@epita.fr>
111
112 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
113 on that of lib/error.c.
114
115 2001-12-12 Akim Demaille <akim@epita.fr>
116
117 Some hosts don't like `/' in includes.
118
119 * src/system.h: Include libgettext.h without qualifying the path.
120 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
121 $(top_srcdir).
122
123 2001-12-11 Marc Autret <autret_m@epita.fr>
124
125 * src/output.c (output_parser): Remove useless muscle.
126
127 2001-12-11 Marc Autret <autret_m@epita.fr>
128
129 * src/bison.simple: Remove #line just before %%epilogue. It
130 is now handled in ...
131 * src/reader.c (read_additionnal_code): Add the output of a
132 #line for the epilogue.
133
134 2001-12-10 Marc Autret <autret_m@epita.fr>
135
136 * src/reader.c (copy_definition): Re-use CPP-outed code which
137 replace precedent remove.
138 * src/bison.simple: Remove #line before %%prologue because
139 %%input-line is wrong at this time.
140
141 2001-12-10 Marc Autret <autret_m@epita.fr>
142
143 * src/reader.c (symbols_output): Clean up.
144 * src/output.c (output_gram, output): Clean up.
145
146 2001-12-10 Akim Demaille <akim@epita.fr>
147
148 * src/lalr.c (initialize_lookaheads): New. Extracted from...
149 * src/LR0.c (set_state_table): here.
150 * src/lalr.c (lalr): Call it.
151
152 2001-12-10 Akim Demaille <akim@epita.fr>
153
154 * src/state.h (shifts): Remove the `number' member: shifts are
155 attached to state, hence no longer need to be labelled with a
156 state number.
157
158 2001-12-10 Akim Demaille <akim@epita.fr>
159
160 Now that states have a complete set of members, the linked list of
161 shifts is useless: just fill directly the state's shifts member.
162
163 * src/state.h (shifts): Remove the `next' member.
164 * src/LR0.c (first_state, last_state): Remove.
165 Adjust the callers.
166 (augment_automaton): Don't look for the shifts that must be added
167 a shift on EOF: it is those of the state we looked for! But now,
168 since shifts are attached, it is no longer needed to looking
169 merely by its id: its number.
170
171 2001-12-10 Akim Demaille <akim@epita.fr>
172
173 * src/LR0.c (augment_automaton): Better variable locality.
174 Remove an impossible branch: if there is a state corresponding to
175 the start symbol being shifted, then there is shift for the start
176 symbol from the initial state.
177
178 2001-12-10 Akim Demaille <akim@epita.fr>
179
180 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
181 only when appropriate: when insert_start_shifting_state' is not
182 invoked.
183 * tests/regression.at (Rule Line Numbers): Adjust.
184
185 2001-12-10 Akim Demaille <akim@epita.fr>
186
187 * src/LR0.c (augment_automaton): Now that all states have shifts,
188 merge the two cases addition shifts to the initial state.
189
190 2001-12-10 Akim Demaille <akim@epita.fr>
191
192 * src/lalr.c (set_state_table): Move to...
193 * src/LR0.c: here.
194 * src/lalr.c (lalr): Don't call it...
195 * src/LR0.c (generate_states): do it.
196 * src/LR0.h (first_state): Remove, only the table is used.
197
198 2001-12-10 Akim Demaille <akim@epita.fr>
199
200 * src/LR0.h (first_shift, first_reduction): Remove.
201 * src/lalr.c: Don't use first_shift: find shifts through the
202 states.
203
204 2001-12-10 Akim Demaille <akim@epita.fr>
205
206 * src/LR0.c: Attach shifts to states as soon as they are
207 computed.
208 * src/lalr.c (set_state_table): Instead of assigning shifts to
209 state, just assert that the mapping was properly done.
210
211 2001-12-10 Akim Demaille <akim@epita.fr>
212
213 * src/LR0.c (insert_start_shift): Rename as...
214 (insert_start_shifting_state): this.
215 (insert_eof_shifting_state, insert_accepting_state): New.
216 (augment_automaton): Adjust.
217 Better locality of the variables.
218 When looking if the start_symbol is shifted from the initial
219 state, using `while (... symbol != start_symbol ...)' sounds
220 better than `while (... symbol < start_symbol ...)': If fail
221 to see how the order between symbols could be relevant!
222
223 2001-12-10 Akim Demaille <akim@epita.fr>
224
225 * src/getargs.h: Don't declare `spec_name_prefix' and
226 `spec_file_prefix', declared by src/files.h.
227 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
228 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
229 * src/output.c (prepare): Adjust.
230 * src/reader.c (symbols_output): Likewise.
231 * src/vmsgetargs.c: Vaguely adjust, but who cares?
232
233 2001-12-10 Akim Demaille <akim@epita.fr>
234
235 * src/muscle_tab.c (muscle_init): NULL is a better default than
236 `"0"'.
237
238 2001-12-10 Akim Demaille <akim@epita.fr>
239
240 * src/reader.c (reader): Calling symbols_output once is enough.
241
242 2001-12-10 Akim Demaille <akim@epita.fr>
243
244 Now that states have a complete set of members, the linked list of
245 reductions is useless: just fill directly the state's reductions
246 member.
247
248 * src/state.h (struct reductions): Remove member `number' and
249 `next'.
250 * src/LR0.c (first_reduction, last_reduction): Remove.
251 (save_reductions): Don't link the new reductions, store them in
252 this_state.
253 * src/lalr.c (set_state_table): No need to attach reductions to
254 states, it's already done.
255 * src/output.c (output_actions): No longer free the shifts, then
256 the reductions, then the states: free all the states and their
257 members.
258
259 2001-12-10 Akim Demaille <akim@epita.fr>
260
261 * src/options.c (OPTN, DRTV, BOTH): New.
262 (option_table): Use them.
263
264 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
265 the job of system.h.
266 * src/options.c: Don't include stdio.h and xalloc.h for the same
267 reasons.
268
269 2001-12-10 Akim Demaille <akim@epita.fr>
270
271 * src/output.c (output, prepare): Make sure the values of the
272 muscles `action' and `prologue' are 0-terminated.
273
274 2001-12-10 Akim Demaille <akim@epita.fr>
275
276 Clean up GCC warnings.
277
278 * src/reader.c (copy_action): `buf' is not used.
279 (parse_skel_decl): Be static.
280 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
281 * src/options.h (create_long_option_table): Have a real prototype.
282 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
283 (hash_delete_at): Return const void *.
284 Adjust casts to preserve the const.
285
286 2001-12-10 Akim Demaille <akim@epita.fr>
287
288 * configure.in: Require 2.52g.
289 M4 is not needed, but AUTOM4TE is.
290 * m4/m4.m4: Remove.
291 * tests/Makefile.am: Adjust.
292
293 2001-12-10 Akim Demaille <akim@epita.fr>
294
295 One structure for states is enough, even though theoretically
296 there are LR(0) states and LALR(1) states.
297
298 * src/lalr.h (state_t): Remove.
299 (state_table): Be state_t **, not state_t *.
300 * src/state.h (core, CORE_ALLOC): Rename as...
301 (state_t, STATE_ALLOC): this.
302 Add the LALR(1) members: shifts, reductions, errs.
303 * src/LR0.c (state_table): Rename as...
304 (state_hash): this, to avoid name clashes with the global
305 `state_table'.
306 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
307 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
308
309 2001-12-10 Akim Demaille <akim@epita.fr>
310
311 Bison dumps core on bash.y.
312 Reported by Pascal Bart.
313
314 * src/warshall.c (bitmatrix_print): New.
315 (TC): Use it.
316 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
317 j must be the outer loop.
318 * tests/regression.at (Broken Closure): New.
319
320 2001-12-05 Akim Demaille <akim@epita.fr>
321
322 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
323 its argument.
324 Reported by Peter Hámorský.
325
326 2001-12-05 Akim Demaille <akim@epita.fr>
327
328 * src/conflicts.c (err_table): Remove.
329 (resolve_sr_conflict): Adjust.
330 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
331 Rename as...
332 (state_t.reductions, state_t.shifts): this.
333
334 2001-12-05 Akim Demaille <akim@epita.fr>
335
336 * src/reduce.c (reduce_grammar_tables): No longer disable the
337 removal of useless rules via CPP but via `if (0)', so that the
338 compiler still check the code is valid.
339 For instance, it should have noticed `rline' no longer exists: use
340 the `line' member of rule_t.
341 * src/gram.c (dummy, rline): Remove, unused.
342
343 2001-12-05 Akim Demaille <akim@epita.fr>
344
345 * src/output.c (pack_vector): Use assert, not berror.
346 * src/main.c (berror): Remove, unused.
347
348 2001-12-05 Akim Demaille <akim@epita.fr>
349
350 New experimental feature: if --verbose --trace output all the
351 items of a state, not only its kernel.
352
353 * src/print.c (print_core): If `trace_flag', then invoke closure
354 before outputting the items of the state (print_core is no longer
355 a correct name them).
356 (print_results): Invoke new_closure/free_closure if needed.
357
358 2001-12-05 Akim Demaille <akim@epita.fr>
359
360 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
361 * src/closure.c, src/closure.h (itemsetsize): Rename as...
362 (nitemset): for consistency with the rest of the project.
363
364 2001-12-05 Akim Demaille <akim@epita.fr>
365
366 * src/closure.c (print_closure): Improve.
367 (closure): Use it for printing input and output.
368
369 2001-12-05 Akim Demaille <akim@epita.fr>
370
371 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
372 indexed by nonterminals.
373
374 2001-12-05 Akim Demaille <akim@epita.fr>
375
376 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
377 what it was!).
378 * src/warshall.h: Remove accidental duplication of the content.
379
380 2001-12-05 Akim Demaille <akim@epita.fr>
381

391
392 2001-12-05 Akim Demaille <akim@epita.fr>
393
394 * src/output.c (action_row): De-obfuscate
395 using the good o' techniques: arrays not pointers, variable
396 locality, BITISSET, RESETBIT etc.
397
398 2001-12-05 Akim Demaille <akim@epita.fr>
399
400 Pessimize the code to simplify it: from now on, all the states
401 have a valid SHIFTS, which NSHIFTS is possibly 0.
402
403 * src/LR0.c (shifts_new): Be global and move to..
404 * src/state.c, src/state.h: here.
405 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
406 * src/print_graph: Adjust.
407
408 2001-12-05 Akim Demaille <akim@epita.fr>
409
410 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
411 * src/conflicts.c: Use it.
412 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
413 incorrectly ``simplified''.
414
415 2001-12-05 Akim Demaille <akim@epita.fr>
416
417 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
418 using the good o' techniques: arrays not pointers, variable
419 locality, BITISSET, RESETBIT etc.
420
421 2001-12-05 Akim Demaille <akim@epita.fr>
422
423 * src/state.h (SHIFT_SYMBOL): New.
424 * src/conflicts.c: Use it to deobfuscate.
425
426 2001-12-05 Akim Demaille <akim@epita.fr>
427
428 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
429 (print_reductions): De-obfuscate using the good o' techniques:
430 arrays not pointers, variable locality, BITISSET.
431
432 2001-12-05 Akim Demaille <akim@epita.fr>
433
434 * src/conflicts.c (print_reductions): Arrays, not pointers.
435 Use BITISSET.
436
437 2001-12-05 Akim Demaille <akim@epita.fr>
438
439 * src/conflicts.c (print_reductions): Pessimize, but clarify.
440
441 2001-12-05 Akim Demaille <akim@epita.fr>
442
443 * src/conflicts.c (print_reductions): Improve variable locality.
444
445 2001-12-05 Akim Demaille <akim@epita.fr>
446
447 * src/conflicts.c (print_reductions): Pessimize, but clarify.
448
449 2001-12-05 Akim Demaille <akim@epita.fr>
450
451 * src/conflicts.c (print_reductions): Improve variable locality.
452
453 2001-12-05 Akim Demaille <akim@epita.fr>
454
455 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
456 * src/lalr.c: Use them.
457
458 2001-12-05 Akim Demaille <akim@epita.fr>
459
460 * src/LR0.c (augment_automaton): Formatting changes.
461 Better variable locality.
462
463 2001-12-05 Akim Demaille <akim@epita.fr>
464
465 * src/lalr.c (matrix_print): New.
466 (transpose): Use it.
467 Use arrays instead of pointers.
468
469 2001-12-05 Akim Demaille <akim@epita.fr>
470
471 * src/lalr.c (maxrhs): Move to...
472 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
473 * src/lalr.c (build_relations): Adjust.
474
475 2001-12-05 Akim Demaille <akim@epita.fr>
476
477 * src/lalr.c (transpose): Free the memory allocated to the
478 argument, as it is replaced by the results by the unique caller.
479 (build_relations): Merely invoke transpose: it handles the memory
480 deallocation.
481 Improve variable locality.
482 Avoid variables used as mere abbreviations.
483 (compute_lookaheads): Use arrays instead of pointers.
484
485 2001-12-05 Akim Demaille <akim@epita.fr>
486
487 * src/lalr.c (initialize_F): Improve variable locality.
488 Avoid variables used as mere abbreviations.
489
490 2001-12-05 Akim Demaille <akim@epita.fr>
491
492 * src/derives.c (print_derives): Display the ruleno.
493 * src/lalr.c (initialize_F, transpose): Better variable locality
494 to improve readability.
495 Avoid variables used as mere abbreviations.
496
497 2001-12-05 Akim Demaille <akim@epita.fr>
498
499 * src/lalr.c (traverse): Use arrays instead of pointers.
500
501 2001-12-05 Akim Demaille <akim@epita.fr>
502
503 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
504 the handling of squeue.
505 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
506
507 2001-12-05 Akim Demaille <akim@epita.fr>
508
509 Because useless nonterminals are now kept alive (instead of being
510 `destroyed'), we now sometimes examine them, and store information
511 related to them. Hence we need to know their number, and adjust
512 memory allocations.
513
514 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
515 static.
516 * src/LR0.c (allocate_itemsets): The memory allocated to
517 `symbol_count' was used for two different purpose: once to count
518 the number of occurrences of each symbol, and later reassigned to
519 `shift_symbol', containing the symbol that can be shifted from a
520 given state.
521 Deobfuscate, i.e., allocate, use and free `symbol_count' here
522 only, and...
523 (new_itemsets): Allocate `shift_symbol' here.
524 (allocate_itemsets): symbol_count includes useless nonterminals.
525 Make room for them.
526 (free_storage): Use `free', not `XFREE', for pointers that cannot
527 be null.
528
529 2001-12-05 Akim Demaille <akim@epita.fr>
530
531 * src/nullable.c (set_nullable): Deobfuscate the handling of
532 ritem.
533 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
534
535 2001-12-05 Akim Demaille <akim@epita.fr>
536
537 * src/gram.c, src/gram.h (ritem_print): New.
538 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
539 (This useless function was defined only to work around VMS linkers
540 that can't handle compilation units with variables only).
541 * src/reduce.c (dump_grammar): Use it to trace the construction of
542 ritem.
543
544 2001-12-04 Paul Eggert <eggert@twinsun.com>
545
546 * src/bison.simple (union yyalloc): Change member names
547 to be the same as the stack names.
548 (yyparse): yyptr is now union yyalloc *, not char *.
549 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
550 and may generate better code on some machines.
551 (yystpcpy): Use prototype if __STDC__ is defined, not just
552 if __cplusplus is defined.
553
554 2001-11-30 Akim Demaille <akim@epita.fr>
555
556 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
557 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
558 Gettext doesn't compile cleanly, and dies with -Werror.
559 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
560 Include WARNING_CFLAGS here.
561 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
562 before being defined.
563
564 2001-11-27 Paul Eggert <eggert@twinsun.com>
565
566 * lib/quotearg.h (quotearg_n, quotearg_n_style):
567 First arg is int, not unsigned.
568 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
569 (SIZE_MAX, UINT_MAX): New macros.
570 (quotearg_n_options): Abort if N is negative.
571 Avoid overflow check on hosts where size_t is 64 bits and int
572 is 32 bits, as overflow is impossible there.
573 Fix off-by-one typo that caused unnecessary reallocation.
574
575 2001-11-29 Paul Eggert <eggert@twinsun.com>
576

581
582 * src/bison.simple:
583 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
584 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
585 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
586
587 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
588 on user names when possible.
589
590 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
591 Simplify test for whather <alloca.h> exists.
592
593 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
594
595 (<stdio.h>): Include if YYDEBUG.
596
597 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
598 ! defined (yyoverflow) && ! defined (yymemcpy).
599
600 (yymemcpy, yyparse): Rename local variables as needed so that
601 they all begin with 'yy'.
602
603 (yystrlen, yystpcpy): New functions.
604
605 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
606 All uses changed.
607
608 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
609 instead of relying on string.h functions. Use YYSTACK_ALLOC
610 and YYSTACK_FREE instead of malloc and free.
611
612 2001-11-30 Akim Demaille <akim@epita.fr>
613
614 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

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

652
653 2001-11-30 Akim Demaille <akim@epita.fr>

656 (nonterminals_reduce): New, extracted from...
657 (reduce_grammar_tables): here.

663 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
664 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
665 New macros.
666 (union yyalloc): New type.
667 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
668 an arbitrary restriction on hosts where size_t is wider than int.
669
670 (yyparse): Don't dump core if alloca or malloc fails; instead, report
671 a parser stack overflow. Allocate just one block of memory for all
672 three stacks, instead of allocating three blocks; this typically is
673 faster and reduces fragmentation.
674
675 Do not limit the number of items in the stack to a value that fits
676 in 'int', as this is an arbitrary limit on hosts with 64-bit
677 size_t and 32-bit int.
678
679 2001-11-29 Marc Autret <autret_m@epita.fr>

726
727 2001-11-28 Akim Demaille <akim@epita.fr>
728
729 * src/closure.c (closure): `b' and `ruleno' denote the same value:

733
734 * src/closure.c (closure): Instead of looping over word in array

1003
1004 2001-11-19 Akim Demaille <akim@epita.fr>
1005
1006 * src/vcg.c: You do the output, so you are responsible of the
1007 handling of VCG syntax, in particular: use quotearg.
1008 * src/print_graph.c: Don't.
1009 (print_actions): Don't output the actions as part of the nodes,
1010 since that's the job of the edges.

1103
1104 * tests/calc.at, tests/output.at, tests/regression.at,
1105 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
1106 now the tests are run in private dirs, therefore AC_CLEANUP and

1109 use abs. path to find config.h.
1110 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

1132 braces to pacify GCC's warnings for `if () if () {} else {}'.
1133 * src/lex.c (parse_percent_token): Replace equal_offset with
1134 arg_offset.
1135 arg is const.

2494 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

2507 (init_lex): Initialize it. No longer call...
2508 (grow_token_buffer): this. Remove it.

2510
2511 2001-01-19 Akim Demaille <akim@epita.fr>
2512
2513 * src/lex.h: Rename all the tokens:
2514 s/\bENDFILE\b/tok_eof/g;

2529 * src/lex.c (percent_table): Also accept `%yacc',
2530 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

2532 Handle the actions for `%semantic_parser' and `%pure_parser' here,
2533 instead of returning a token.
2534 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
2535 * src/reader.c (read_declarations): Adjust.
2536 * src/files.c (open_files): Don't call `compute_base_names', don't
2537 compute `attrsfile' since they depend upon data which might be
2538 *in* the input file now.
2539 (output_files): Do it here.
2540 * src/output.c (output_headers): Document the fact that this patch
2541 introduces a guaranteed SEGV for semantic parsers.
2542 * doc/bison.texinfo: Document them.

2563
2564 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
2565 (copy_dollar): Now that everything uses obstacks, get rid of the
2566 FILE * parameters.
2567
2568 2000-12-20 Akim Demaille <akim@epita.fr>
2569
2570 * src/files.c (open_files): Actually the `.output' file is based

2599 * src/files.c (strsuffix): New.
2600 (stringappend): Be just like strcat but allocate.
2601 (base_names): Eve out from open_files.
2602 Try to simplify the rather hairy computation of base_name and
2603 short_base_name.
2604 (open_files): Use it.
2605 * tests/suite.at (Checking output file names): New test.
2606

2642
2643 2000-12-19 Akim Demaille <akim@epita.fr>
2644
2645 * src/files.c (open_files): Yipee! We no longer need all the code

2649
2650 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

2678 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
2679 prevents type checking.
2680 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
2681 cast the value to (void *): assigning a `foo *' to a `void *'
2682 variable is valid.
2683 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
2684 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

2701 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
2702 macros.

2730 Qualify it `const'.
2731 (obstack_copy, obstack_copy0): Rename the second argument as
2732 `address' for consistency. Qualify it `const'.
2733 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
2734 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
2735 `const' their input argument (`data' or `address').

2762 (output_files): this.
2763 Use `obstack_save'.

2830
2831 * src/lex.c (read_typename): New function.
2832 (lex): Use it.
2833 * src/reader.c (copy_dollar): Likewise.
2834
2835 2000-10-16 Akim Demaille <akim@epita.fr>
2836
2837 * src/reader.c (copy_comment2): Expect the input stream to be on
2838 the `/' which is suspected to open a comment, instead of being
2839 called after `//' or `/*' was read.
2840 (copy_comment, copy_definition, parse_union_decl, copy_action)
2841 (copy_guard): Adjust.
2842
2843 2000-10-16 Akim Demaille <akim@epita.fr>

2868
2869 2000-10-04 Akim Demaille <akim@epita.fr>
2870
2871 When a literal string is used to define two different tokens,
2872 `bison -v' segfaults.
2873 Reported by Piotr Gackiewicz, and fixed by Neil Booth.

2881
2882 * src/reader.c (parse_expect_decl): Keep `count' within the size
2883 of `buffer'.
2884 From Neil Booth.
2885
2886 2000-10-02 Paul Eggert <eggert@twinsun.com>
2887
2888 * bison.s1 (yyparse): Assign the default value
2889 unconditionally, to avoid a GCC warning and make the parser a
2890 tad smaller.
2891
2892 2000-10-02 Akim Demaille <akim@epita.fr>
2893
2894 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
2895 options.
2896
2897 2000-10-02 Akim Demaille <akim@epita.fr>
2898
2899 * src/derives.c, src/print.c, src/reduce.c: To ease the
2900 translation, move some `\n' out of the translated strings.
2901
2902 2000-10-02 Akim Demaille <akim@epita.fr>
2903
2904 The location tracking mechanism is precious for parse error
2905 messages. Nevertheless, it is enabled only when `@n' is used in
2906 the grammar, which is a different issue (you can use it in error
2907 message, but not in the grammar per se). Therefore, there should
2908 be another means to enable it.
2909
2910 * src/getargs.c (getargs): Support `--locations'.
2911 (usage): Report it.
2912 * src/getargs.h (locationsflag): Export it.
2913 * src/lex.c (percent_table): Support `%locations'.
2914 * src/reader.c (yylsp_needed): Remove this variable, now replaced
2915 with `locationsflag'.
2916 * doc/bison.texinfo: Document `--locations' and `%locations'.
2917 Sort the options.
2918 * tests/calc.m4: Test it.
2919
2920 For regularity of the names, replace each
2921 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2922 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2923 In addition replace each `flag' with `_flag'.
2924
2925 2000-10-02 Akim Demaille <akim@epita.fr>
2926
2927 Also test parse error messages, including with YYERROR_VERBOSE.
2928
2929 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2930 associative).
2931 Use it to check the computations.
2932 Use it to check `nonassoc' is honored.
2933 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2934 `--yyerror-verbose'.
2935 (_AT_CHECK_CALC): Adjust to this option.
2936 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2937
2938 2000-10-02 Akim Demaille <akim@epita.fr>
2939
2940 Test also `--verbose', `--defines' and `--name-prefix'. Testing
2941 the latter demonstrates a flaw in the handling of non debugging
2942 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2943 was used in order to simplify:
2944
2945 #if YYDEBUG
2946 if (yydebug)
2947 {
2948 ...
2949 }
2950 #endif
2951
2952 into
2953
2954 if (yydebug)
2955 {
2956 ...
2957 }
2958
2959 unfortunately this leads to a CPP conflict when
2960 `--name-prefix=foo' is used since it produces `#define yydebug
2961 foodebug'.
2962
2963 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2964 (YYDPRINTF): New macro.
2965 Spread its use.
2966 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2967 the bison options.
2968 Also test `--verbose', `--defines' and `--name-prefix'.
2969
2970 2000-10-02 Akim Demaille <akim@epita.fr>
2971
2972 Improve the readability of the produced parsers.
2973
2974 * src/bison.s1: Formatting changes.
2975 Improve the comment related to the `$' mark.
2976 (yydefault): Don't fall through to `yyresume': `goto' there.
2977 * src/output.c (output_parser): When the `$' is met, skip the end
2978 of its line.
2979 New variable, `number_of_dollar_signs', to check there's exactly
2980 one `$' in the parser skeleton.
2981
2982 2000-10-02 Akim Demaille <akim@epita.fr>
2983
2984 * lib/xstrdup.c: New file, from the fileutils.
2985 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2986 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2987 instead of strlen + xmalloc + strcpy.
2988 * src/symtab.c (copys): Remove, use xstrdup instead.
2989
2990 2000-10-02 Akim Demaille <akim@epita.fr>
2991
2992 * src/gram.h (associativity): New enum type which replaces the
2993 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2994 `right_assoc', `left_assoc' and `non_assoc'.
2995 Adjust all dependencies.
2996 * src/reader.c: Formatting changes.
2997 (LTYPESTR): Don't define it, use it as a literal in
2998 `reader_output_yylsp'.
2999 * src/symtab.h (symbol_class): New enum type which replaces the
3000 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3001 `sunknown', `stoken and `snterm'.
3002
3003 2000-10-02 Akim Demaille <akim@epita.fr>
3004
3005 * src/getargs.c (fixed_outfiles): Rename as...
3006 (yaccflag): for consistency and accuracy.
3007 Adjust dependencies.
3008
3009 2000-10-02 Akim Demaille <akim@epita.fr>
3010
3011 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3012 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
3013 difficult and introduced a lot of core dump. It turns out that
3014 Bison used an implementation of `xmalloc' based on `calloc', and
3015 at various places it does depend upon the initialization to 0. I
3016 have not tried to isolate the pertinent places, and all the former
3017 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
3018 someone should address this issue.
3019
3020 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3021 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

3028
3029 Various anti-`extern in *.c' changes.
3030
3031 * src/system.h: Include `assert.h'.
3032
3033 2000-10-02 Akim Demaille <akim@epita.fr>
3034
3035 * src/state.h (nstates, final_state, first_state, first_shift)
3036 (first_reduction): Move their exportation from here...
3037 * src/LR0.h: to here.
3038 Adjust dependencies.
3039 * src/getargs.c (statisticsflag): New variable.
3040 Add support for `--statistics'.
3041 Adjust dependencies.
3042

3046
3047 * src/LR0.h: New file.

3064 Adjust dependencies.
3065 * src/conflicts.h: New file.
3066 Propagate its inclusion.
3067
3068 2000-10-02 Akim Demaille <akim@epita.fr>
3069

3117 output_short_table.
3118
3119 2000-10-02 Akim Demaille <akim@epita.fr>
3120
3121 `user_toknums' is output as a `short[]' in `output.c', while it is
3122 defined as a `int[]' in `reader.c'. For consistency with the
3123 other output tables, `user_toknums' is now defined as a table of
3124 shorts.
3125
3126 * src/reader.c (user_toknums): Be a short table instead of an int
3127 table.
3128 Adjust dependencies.
3129
3130 Factor the short table outputs.
3131

3133 * src/output.c (output_gram, output_stos, output_rule_data)
3134 (output_base, output_table, output_check): Use it.
3135
3136 2000-10-02 Akim Demaille <akim@epita.fr>
3137
3138 * src/output.c (output): Topological sort of the functions, in
3139 order to get rid of the `static' prototypes.
3140 No longer use `register'.
3141 * src/output.h: New file.

3143 from output.c.

3165 inclusion.
3166 Don't define PARAMS.
3167 * src/system.h: Define PARAMS.
3168 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3169 purpose of config.h. system.h must not try to fix wrong
3170 definitions in config.h.
3171
3172 2000-09-20 Akim Demaille <akim@epita.fr>
3173
3174 * src/derives.h: New file.

3306 * Makefile.am (SUBDIRS): Adjust.

3387
3388 Change the handling of @s so that they behave exactly like $s.
3389 There is now a pseudo variable @$ (readble and writable), location
3390 of the lhs of the rule (by default ranging from the location of
3391 the first symbol of the rhs, to the location of the last symbol,
3392 or, if the rhs is empty, YYLLOC).

3395 yyval.
3396 (yyparse): When providing a default semantic action, provide a

3427 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3428 One `#if YYDEBUG' remains, since it uses variables which are
3429 defined only if `YYDEBUG != 0'.

3431 2000-03-16 Akim Demaille <akim@epita.fr>
3432

4152 buffer while reading an integer.
4153 (parse_percent_token): Replaced if-else statement with percent_table.
4154 (parse_percent_token): Added % declarations as another
4155 way to specify the flags -n, -l, and -r. Also added hooks for
