1 2001-12-27 Akim Demaille <akim@epita.fr>
2
3 All the hacks using a final pseudo state are now useless.
4
5 * src/LR0.c (set_state_table): state_table holds exactly nstates.
6 * src/lalr.c (nLA): New.
7 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
8 instead of lookaheadsp from the pseudo state (nstate + 1).
9
10 2001-12-27 Akim Demaille <akim@epita.fr>
11
12 * src/output.c (action_row, token_actions): Use a state_t instead
13 of a integer, and nlookaheads instead of the following state's
14 lookaheadsp.
15
16
17 2001-12-27 Akim Demaille <akim@epita.fr>
18
19 * src/conflicts.c (log_resolution, flush_shift)
20 (resolve_sr_conflict, set_conflicts, solve_conflicts)
21 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
22 (conflicts_print, print_reductions): Use a state_t instead of an
23 integer when referring to a state.
24 As much as possible, depend upon nlookaheads, instead of the
25 `lookaheadsp' member of the following state (since lookaheads of
26 successive states are successive, the difference between state n + 1
27 and n served as the number of lookaheads for state n).
28 * src/lalr.c (add_lookback_edge): Likewise.
29 * src/print.c (print_core, print_actions, print_state)
30 (print_results): Likewise.
31 * src/print_graph.c (print_core, print_actions, print_state)
32 (print_graph): Likewise.
33 * src/conflicts.h: Adjust.
34
35 2001-12-27 Akim Demaille <akim@epita.fr>
36
37 * src/bison.hairy: Formatting/comment changes.
38 ANSIfy.

40 Add plenty of `static'.
41
42 2001-12-27 Akim Demaille <akim@epita.fr>
43
44 * src/output.c (prepare): Drop the muscle `ntbase' which
45 duplicates ntokens.
46 * src/bison.simple: Formatting/comment changes.
47 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
48 is an undocumented synonym.
49
50
51 2001-12-22 Akim Demaille <akim@epita.fr>
52
53 * src/output.c (output_table_data): Change the prototype to use
54 `int' for array ranges: some invocations do pass an int, not a
55 short.
56 Reported by Wayne Green.
57
58 2001-12-22 Akim Demaille <akim@epita.fr>
59
60 Some actions of web2c.y are improperly triggered.
61 Reported by Mike Castle.
62
63 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

67
68 2001-12-22 Akim Demaille <akim@epita.fr>

75
76 2001-12-18 Akim Demaille <akim@epita.fr>

79 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
80 Reported by Nelson Beebee.
81
82 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
83 `#define it_succeeded 0' and `assert (it_succeeded)'.
84
85 2001-12-17 Marc Autret <autret_m@epita.fr>
86
87 * src/bison.simple: Don't hard code the skeleton line and filename.
88 * src/output.c (output_parser): Rename 'line' as 'output_line'.
89 New line counter 'skeleton_line' (skeleton-line muscle).
90
91 2001-12-17 Paul Eggert <eggert@twinsun.com>
92
93 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
94 YYDEBUG must be defined to a nonzero value.
95

100
101 * src/state.h (state_t): Rename lookaheads as lookaheadsp.

106 state.
107
108 2001-12-17 Akim Demaille <akim@epita.fr>
109
110 * src/files.h, src/files.c (open_files, close_files): Remove.
111 * src/main.c (main): Don't open/close files, nor invoke lex_free,
112 let...
113 * src/reader.c (reader): Do it.
114
115 2001-12-17 Akim Demaille <akim@epita.fr>
116
117 * src/conflicts.c (print_reductions): Formatting changes.
118
119 2001-12-17 Akim Demaille <akim@epita.fr>
120
121 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
122 (flush_reduce): New.
123 (resolve_sr_conflict): Adjust.
124
125 2001-12-17 Akim Demaille <akim@epita.fr>
126
127 * src/output.c (output_obstack): Be static and rename as...
128 (format_obstack): this, to avoid any confusion with files.c's
129 output_obstack.
130 * src/reader.h (muscle_obstack): Move to...
131 * src/output.h: here, since it's defined in output.c.
132
133 2001-12-17 Akim Demaille <akim@epita.fr>
134
135 * src/output.c (action_row, save_column, default_goto)
136 (sort_actions, matching_state, pack_vector): Better variable
137 locality.
138
139 2001-12-17 Akim Demaille <akim@epita.fr>
140
141 * src/output.c: Various formatting changes.
142

150
151 2001-12-16 Marc Autret <autret_m@epita.fr>
152
153 * src/output.c (actions_output): Fix. When we use %no-lines,
154 there is one less line per action.
155
156 2001-12-16 Marc Autret <autret_m@epita.fr>
157
158 * src/bison.simple: Remove a useless #line directive.
159 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
160 * src/output.c (get_lines_number): New.
161 (output_parser): Adjust, now takes care about the lines of a
162 output muscles.
163 Fix line numbering.
164 (actions_output): Computes the number of lines taken by actions.
165 (output_master_parser): Insert new skeleton which is the name of
166 the output parser file name.
167
168 2001-12-15 Marc Autret <autret_m@epita.fr>
169
170 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
171
172 2001-12-15 Marc Autret <autret_m@epita.fr>
173
174 * src/output.c (output_gram): Keep track of the hairy one.
175
176 2001-12-15 Akim Demaille <akim@epita.fr>
177
178 Make `make distcheck' work.
179
180 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
181 system.h which uses libgettext.h.
182
183 2001-12-15 Akim Demaille <akim@epita.fr>
184
185 * src/nullable.c (set_nullable): Useless rules must be skipped,
186 otherwise, since we range over their symbols, we might look at a
187 nonterminal which no longer ``exists'', i.e., it is not counted in
188 `nvars', hence we overflow our arrays.
189
190 2001-12-15 Akim Demaille <akim@epita.fr>
191
192 The header can also be produced directly, without any obstack!
193 Yahoo!
194
195 * src/files.c, src/files.h (defines_obstack): Remove.
196 (compute_header_macro): Global.
197 (defines_obstack_save): Remove.
198 * src/reader.c (parse_union_decl): No longer output to
199 defines_obstack: its content can be found in the `stype' muscle
200 anyway.
201 (output_token_translations): Merge into...
202 (symbols_output): this.
203 Rename as...
204 (symbols_save): this.
205 (reader): Adjust.
206 * src/output.c (header_output): New.
207 (output): Call it.
208
209 2001-12-15 Akim Demaille <akim@epita.fr>
210
211 * src/reader.c (parse_union_decl): Instead of handling two obstack
212 simultaneously, use one to define the `stype' muscle, and use the
213 value of the latter to fill defines_obstack.
214 (copy_comment): Remove.
215 (copy_comment2): Work for a single obstack.
216 Rename as...
217 (copy_comment): this.
218
219 2001-12-15 Akim Demaille <akim@epita.fr>
220
221 * src/lex.c, src/lex.h (xgetc): No longer static.
222 * src/reader.c (parse_union_decl): Revamp.
223
224 2001-12-15 Akim Demaille <akim@epita.fr>
225
226 Still making progress in separating Bison into (i) input, (ii)
227 process, (iii) output: now we can directly output the parser file
228 without using table_obstack at all.
229
230 * src/files.c, src/files.h (table_obstack): Bye bye.
231 (parser_file_name): New.
232 * src/files.c (compute_output_file_names): Compute it.
233 * src/output.c (actions_output, output_parser)
234 (output_master_parser): To a file instead of an obstack.
235
236 2001-12-15 Akim Demaille <akim@epita.fr>
237
238 Attach actions to rules, instead of pre-outputting them to
239 actions_obstack.
240
241 * src/gram.h (rule_t): action and action_line are new members.
242 * src/reader.c (symbol_list): Likewise.
243 (copy_action): Save the actions within the rule.
244 (packgram): Save them in rule_table.
245 * src/output.c (actions_output): New.
246 (output_parser): Use it on `%%actions'.
247 (output_rule_data): Don't free rule_table.
248 (output): Do it.
249 (prepare): Don't save the `action' muscle.
250 * src/bison.simple: s/%%action/%%actions/.
251
252 2001-12-15 Akim Demaille <akim@epita.fr>
253
254 * src/reader.c (copy_action): When --yacc, don't append a `;'
255 to the user action: let it fail if lacking.
256 Suggested by Arnold Robbins and Tom Tromey.
257
258 2001-12-14 Akim Demaille <akim@epita.fr>
259
260 * src/lex.c (literalchar): Simply return the char you decoded, non
261 longer mess around with obstacks and int pointers.
262 Adjust all callers.
263
264 2001-12-14 Akim Demaille <akim@epita.fr>
265
266 * src/lex.c (literalchar): Don't escape the special characters,
267 just decode them, and keep them as char (before, eol was output as
268 the 2 char string `\n' etc.).
269 * src/output.c (output_rule_data): Use quotearg to output the
270 token strings.
271
272 2001-12-13 Paul Eggert <eggert@twinsun.com>
273
274 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
275 Do not infringe on the global user namespace when using C++.
276 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
277 All uses of `fprintf' and `stderr' changed.
278
279 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
280
281 2001-12-13 Akim Demaille <akim@epita.fr>
282
283 The computation of nullable is broken: it doesn't handle empty
284 RHS's properly.
285
286 * tests/torture.at (GNU AWK Grammar): New.
287 * tests/sets.at (Nullable): New.
288 * src/nullable.c (set_nullable): Instead of blindly looping over
289 `ritems', loop over the rules, and then over their rhs's.
290
291 Work around Autotest bugs.
292
293 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
294 frame, because Autotest understand lines starting with a `+' as
295 traces from the shell. Then, they are not processed properly.
296 Admittedly an Autotest bug, but we don't have time to wait for
297 Autotest to catch up.
298 * tests/regression.at (Broken Closure): Adjust to the new table
299 frames.
300 Move to...
301 * tests/sets.at: here.
302
303 2001-12-13 Akim Demaille <akim@epita.fr>
304
305 * src/closure.c (closure): Use nrules instead of playing tricks
306 with BITS_PER_WORD.
307
308 2001-12-13 Akim Demaille <akim@epita.fr>
309
310 * src/print.c (print_actions): Output the handling of `$' as the
311 traces do: shifting the token EOF. Before EOF was treated as a
312 nonterminal.
313 * tests/regression.at: Adjust some tests.
314 * src/print_graph.c (print_core): Complete the set of items via
315 closure. The next-to-final and final states are still unsatisfying,
316 but that's to be addressed elsewhere.
317 No longer output the rule numbers, but do output the state number.
318 A single loop for the shifts + gotos is enough, but picked a
319 distinct color for each.
320 (print_graph): Initialize and finalize closure.
321
322 2001-12-13 Akim Demaille <akim@epita.fr>
323
324 * src/reader.c (readgram): Remove dead code, an strip useless
325 braces.
326 (get_type): Remove, unused.
327
328 2001-12-12 Akim Demaille <akim@epita.fr>
329
330 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
331 on that of lib/error.c.
332
333 2001-12-12 Akim Demaille <akim@epita.fr>
334
335 Some hosts don't like `/' in includes.
336
337 * src/system.h: Include libgettext.h without qualifying the path.
338 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
339 $(top_srcdir).
340
341 2001-12-11 Marc Autret <autret_m@epita.fr>
342
343 * src/output.c (output_parser): Remove useless muscle.
344
345 2001-12-11 Marc Autret <autret_m@epita.fr>
346
347 * src/bison.simple: Remove #line just before %%epilogue. It
348 is now handled in ...
349 * src/reader.c (read_additionnal_code): Add the output of a
350 #line for the epilogue.
351
352 2001-12-10 Marc Autret <autret_m@epita.fr>
353
354 * src/reader.c (copy_definition): Re-use CPP-outed code which
355 replace precedent remove.
356 * src/bison.simple: Remove #line before %%prologue because
357 %%input-line is wrong at this time.
358
359 2001-12-10 Marc Autret <autret_m@epita.fr>
360
361 * src/reader.c (symbols_output): Clean up.
362 * src/output.c (output_gram, output): Clean up.
363
364 2001-12-10 Akim Demaille <akim@epita.fr>
365
366 * src/lalr.c (initialize_lookaheads): New. Extracted from...
367 * src/LR0.c (set_state_table): here.
368 * src/lalr.c (lalr): Call it.
369
370 2001-12-10 Akim Demaille <akim@epita.fr>
371
372 * src/state.h (shifts): Remove the `number' member: shifts are
373 attached to state, hence no longer need to be labelled with a
374 state number.
375
376 2001-12-10 Akim Demaille <akim@epita.fr>
377
378 Now that states have a complete set of members, the linked list of
379 shifts is useless: just fill directly the state's shifts member.
380
381 * src/state.h (shifts): Remove the `next' member.
382 * src/LR0.c (first_state, last_state): Remove.
383 Adjust the callers.
384 (augment_automaton): Don't look for the shifts that must be added
385 a shift on EOF: it is those of the state we looked for! But now,
386 since shifts are attached, it is no longer needed to looking
387 merely by its id: its number.
388
389 2001-12-10 Akim Demaille <akim@epita.fr>
390
391 * src/LR0.c (augment_automaton): Better variable locality.
392 Remove an impossible branch: if there is a state corresponding to
393 the start symbol being shifted, then there is shift for the start
394 symbol from the initial state.
395
396 2001-12-10 Akim Demaille <akim@epita.fr>
397
398 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
399 only when appropriate: when insert_start_shifting_state' is not
400 invoked.
401 * tests/regression.at (Rule Line Numbers): Adjust.
402
403 2001-12-10 Akim Demaille <akim@epita.fr>
404
405 * src/LR0.c (augment_automaton): Now that all states have shifts,
406 merge the two cases addition shifts to the initial state.
407
408 2001-12-10 Akim Demaille <akim@epita.fr>
409
410 * src/lalr.c (set_state_table): Move to...
411 * src/LR0.c: here.
412 * src/lalr.c (lalr): Don't call it...
413 * src/LR0.c (generate_states): do it.
414 * src/LR0.h (first_state): Remove, only the table is used.
415
416 2001-12-10 Akim Demaille <akim@epita.fr>
417
418 * src/LR0.h (first_shift, first_reduction): Remove.
419 * src/lalr.c: Don't use first_shift: find shifts through the
420 states.
421
422 2001-12-10 Akim Demaille <akim@epita.fr>
423
424 * src/LR0.c: Attach shifts to states as soon as they are
425 computed.
426 * src/lalr.c (set_state_table): Instead of assigning shifts to
427 state, just assert that the mapping was properly done.
428
429 2001-12-10 Akim Demaille <akim@epita.fr>
430
431 * src/LR0.c (insert_start_shift): Rename as...
432 (insert_start_shifting_state): this.
433 (insert_eof_shifting_state, insert_accepting_state): New.
434 (augment_automaton): Adjust.
435 Better locality of the variables.
436 When looking if the start_symbol is shifted from the initial
437 state, using `while (... symbol != start_symbol ...)' sounds
438 better than `while (... symbol < start_symbol ...)': If fail
439 to see how the order between symbols could be relevant!
440
441 2001-12-10 Akim Demaille <akim@epita.fr>
442
443 * src/getargs.h: Don't declare `spec_name_prefix' and
444 `spec_file_prefix', declared by src/files.h.
445 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
446 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
447 * src/output.c (prepare): Adjust.
448 * src/reader.c (symbols_output): Likewise.
449 * src/vmsgetargs.c: Vaguely adjust, but who cares?
450
451 2001-12-10 Akim Demaille <akim@epita.fr>
452
453 * src/muscle_tab.c (muscle_init): NULL is a better default than
454 `"0"'.
455
456 2001-12-10 Akim Demaille <akim@epita.fr>
457
458 * src/reader.c (reader): Calling symbols_output once is enough.
459
460 2001-12-10 Akim Demaille <akim@epita.fr>
461
462 Now that states have a complete set of members, the linked list of
463 reductions is useless: just fill directly the state's reductions
464 member.
465
466 * src/state.h (struct reductions): Remove member `number' and
467 `next'.
468 * src/LR0.c (first_reduction, last_reduction): Remove.
469 (save_reductions): Don't link the new reductions, store them in
470 this_state.
471 * src/lalr.c (set_state_table): No need to attach reductions to
472 states, it's already done.
473 * src/output.c (output_actions): No longer free the shifts, then
474 the reductions, then the states: free all the states and their
475 members.
476
477 2001-12-10 Akim Demaille <akim@epita.fr>
478
479 * src/options.c (OPTN, DRTV, BOTH): New.
480 (option_table): Use them.
481
482 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
483 the job of system.h.
484 * src/options.c: Don't include stdio.h and xalloc.h for the same
485 reasons.
486
487 2001-12-10 Akim Demaille <akim@epita.fr>
488
489 * src/output.c (output, prepare): Make sure the values of the
490 muscles `action' and `prologue' are 0-terminated.
491
492 2001-12-10 Akim Demaille <akim@epita.fr>
493
494 Clean up GCC warnings.
495
496 * src/reader.c (copy_action): `buf' is not used.
497 (parse_skel_decl): Be static.
498 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
499 * src/options.h (create_long_option_table): Have a real prototype.
500 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
501 (hash_delete_at): Return const void *.
502 Adjust casts to preserve the const.
503
504 2001-12-10 Akim Demaille <akim@epita.fr>
505
506 * configure.in: Require 2.52g.

508 * m4/m4.m4: Remove.
509 * tests/Makefile.am: Adjust.
510
511 2001-12-10 Akim Demaille <akim@epita.fr>
512
513 One structure for states is enough, even though theoretically
514 there are LR(0) states and LALR(1) states.
515
516 * src/lalr.h (state_t): Remove.
517 (state_table): Be state_t **, not state_t *.
518 * src/state.h (core, CORE_ALLOC): Rename as...
519 (state_t, STATE_ALLOC): this.
520 Add the LALR(1) members: shifts, reductions, errs.
521 * src/LR0.c (state_table): Rename as...
522 (state_hash): this, to avoid name clashes with the global
523 `state_table'.
524 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
525 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
526
527 2001-12-10 Akim Demaille <akim@epita.fr>
528
529 Bison dumps core on bash.y.
530 Reported by Pascal Bart.
531
532 * src/warshall.c (bitmatrix_print): New.
533 (TC): Use it.
534 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
535 j must be the outer loop.
536 * tests/regression.at (Broken Closure): New.
537
538 2001-12-05 Akim Demaille <akim@epita.fr>
539
540 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
541 its argument.
542 Reported by Peter Hámorský.
543
544 2001-12-05 Akim Demaille <akim@epita.fr>
545
546 * src/conflicts.c (err_table): Remove.
547 (resolve_sr_conflict): Adjust.
548 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
549 Rename as...
550 (state_t.reductions, state_t.shifts): this.
551
552 2001-12-05 Akim Demaille <akim@epita.fr>
553
554 * src/reduce.c (reduce_grammar_tables): No longer disable the
555 removal of useless rules via CPP but via `if (0)', so that the
556 compiler still check the code is valid.
557 For instance, it should have noticed `rline' no longer exists: use
558 the `line' member of rule_t.
559 * src/gram.c (dummy, rline): Remove, unused.
560
561 2001-12-05 Akim Demaille <akim@epita.fr>
562
563 * src/output.c (pack_vector): Use assert, not berror.
564 * src/main.c (berror): Remove, unused.
565
566 2001-12-05 Akim Demaille <akim@epita.fr>
567
568 New experimental feature: if --verbose --trace output all the
569 items of a state, not only its kernel.
570
571 * src/print.c (print_core): If `trace_flag', then invoke closure
572 before outputting the items of the state (print_core is no longer
573 a correct name them).
574 (print_results): Invoke new_closure/free_closure if needed.
575
576 2001-12-05 Akim Demaille <akim@epita.fr>
577
578 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
579 * src/closure.c, src/closure.h (itemsetsize): Rename as...
580 (nitemset): for consistency with the rest of the project.
581
582 2001-12-05 Akim Demaille <akim@epita.fr>
583
584 * src/closure.c (print_closure): Improve.
585 (closure): Use it for printing input and output.
586
587 2001-12-05 Akim Demaille <akim@epita.fr>
588
589 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
590 indexed by nonterminals.
591
592 2001-12-05 Akim Demaille <akim@epita.fr>
593
594 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
595 what it was!).
596 * src/warshall.h: Remove accidental duplication of the content.
597
598 2001-12-05 Akim Demaille <akim@epita.fr>
599
600 * src/closure.c (set_fderives): De-obfuscate.
601
602 2001-12-05 Akim Demaille <akim@epita.fr>
603
604 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
605
606 2001-12-05 Akim Demaille <akim@epita.fr>
607
608 * src/closure.c (set_firsts): De-obfuscate.
609
610 2001-12-05 Akim Demaille <akim@epita.fr>
611
612 * src/output.c (action_row): De-obfuscate
613 using the good o' techniques: arrays not pointers, variable
614 locality, BITISSET, RESETBIT etc.
615
616 2001-12-05 Akim Demaille <akim@epita.fr>
617
618 Pessimize the code to simplify it: from now on, all the states
619 have a valid SHIFTS, which NSHIFTS is possibly 0.
620
621 * src/LR0.c (shifts_new): Be global and move to..
622 * src/state.c, src/state.h: here.
623 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
624 * src/print_graph: Adjust.
625
626 2001-12-05 Akim Demaille <akim@epita.fr>
627
628 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
629 * src/conflicts.c: Use it.
630 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
631 incorrectly ``simplified''.
632
633 2001-12-05 Akim Demaille <akim@epita.fr>
634
635 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
636 using the good o' techniques: arrays not pointers, variable
637 locality, BITISSET, RESETBIT etc.
638
639 2001-12-05 Akim Demaille <akim@epita.fr>
640
641 * src/state.h (SHIFT_SYMBOL): New.
642 * src/conflicts.c: Use it to deobfuscate.
643
644 2001-12-05 Akim Demaille <akim@epita.fr>
645
646 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
647 (print_reductions): De-obfuscate using the good o' techniques:
648 arrays not pointers, variable locality, BITISSET.
649
650 2001-12-05 Akim Demaille <akim@epita.fr>
651
652 * src/conflicts.c (print_reductions): Arrays, not pointers.
653 Use BITISSET.
654
655 2001-12-05 Akim Demaille <akim@epita.fr>
656
657 * src/conflicts.c (print_reductions): Pessimize, but clarify.
658
659 2001-12-05 Akim Demaille <akim@epita.fr>
660
661 * src/conflicts.c (print_reductions): Improve variable locality.
662
663 2001-12-05 Akim Demaille <akim@epita.fr>
664
665 * src/conflicts.c (print_reductions): Pessimize, but clarify.
666
667 2001-12-05 Akim Demaille <akim@epita.fr>
668
669 * src/conflicts.c (print_reductions): Improve variable locality.
670
671 2001-12-05 Akim Demaille <akim@epita.fr>
672
673 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
674 * src/lalr.c: Use them.
675
676 2001-12-05 Akim Demaille <akim@epita.fr>
677
678 * src/LR0.c (augment_automaton): Formatting changes.
679 Better variable locality.
680
681 2001-12-05 Akim Demaille <akim@epita.fr>
682
683 * src/lalr.c (matrix_print): New.
684 (transpose): Use it.
685 Use arrays instead of pointers.
686
687 2001-12-05 Akim Demaille <akim@epita.fr>
688
689 * src/lalr.c (maxrhs): Move to...
690 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
691 * src/lalr.c (build_relations): Adjust.
692
693 2001-12-05 Akim Demaille <akim@epita.fr>
694
695 * src/lalr.c (transpose): Free the memory allocated to the
696 argument, as it is replaced by the results by the unique caller.
697 (build_relations): Merely invoke transpose: it handles the memory
698 deallocation.
699 Improve variable locality.
700 Avoid variables used as mere abbreviations.
701 (compute_lookaheads): Use arrays instead of pointers.
702
703 2001-12-05 Akim Demaille <akim@epita.fr>
704
705 * src/lalr.c (initialize_F): Improve variable locality.
706 Avoid variables used as mere abbreviations.
707
708 2001-12-05 Akim Demaille <akim@epita.fr>
709
710 * src/derives.c (print_derives): Display the ruleno.
711 * src/lalr.c (initialize_F, transpose): Better variable locality
712 to improve readability.
713 Avoid variables used as mere abbreviations.
714
715 2001-12-05 Akim Demaille <akim@epita.fr>
716
717 * src/lalr.c (traverse): Use arrays instead of pointers.
718
719 2001-12-05 Akim Demaille <akim@epita.fr>
720
721 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
722 the handling of squeue.
723 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
724
725 2001-12-05 Akim Demaille <akim@epita.fr>
726
727 Because useless nonterminals are now kept alive (instead of being
728 `destroyed'), we now sometimes examine them, and store information
729 related to them. Hence we need to know their number, and adjust
730 memory allocations.
731
732 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
733 static.
734 * src/LR0.c (allocate_itemsets): The memory allocated to
735 `symbol_count' was used for two different purpose: once to count
736 the number of occurrences of each symbol, and later reassigned to
737 `shift_symbol', containing the symbol that can be shifted from a
738 given state.
739 Deobfuscate, i.e., allocate, use and free `symbol_count' here
740 only, and...
741 (new_itemsets): Allocate `shift_symbol' here.
742 (allocate_itemsets): symbol_count includes useless nonterminals.
743 Make room for them.
744 (free_storage): Use `free', not `XFREE', for pointers that cannot
745 be null.
746
747 2001-12-05 Akim Demaille <akim@epita.fr>
748
749 * src/nullable.c (set_nullable): Deobfuscate the handling of
750 ritem.
751 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
752
753 2001-12-05 Akim Demaille <akim@epita.fr>
754
755 * src/gram.c, src/gram.h (ritem_print): New.
756 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
757 (This useless function was defined only to work around VMS linkers
758 that can't handle compilation units with variables only).
759 * src/reduce.c (dump_grammar): Use it to trace the construction of
760 ritem.
761
762 2001-12-04 Paul Eggert <eggert@twinsun.com>
763
764 * src/bison.simple (union yyalloc): Change member names
765 to be the same as the stack names.
766 (yyparse): yyptr is now union yyalloc *, not char *.
767 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
768 and may generate better code on some machines.
769 (yystpcpy): Use prototype if __STDC__ is defined, not just
770 if __cplusplus is defined.
771
772 2001-11-30 Akim Demaille <akim@epita.fr>
773
774 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
775 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
776 Gettext doesn't compile cleanly, and dies with -Werror.
777 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
778 Include WARNING_CFLAGS here.
779 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
780 before being defined.
781
782 2001-11-27 Paul Eggert <eggert@twinsun.com>
783
784 * lib/quotearg.h (quotearg_n, quotearg_n_style):
785 First arg is int, not unsigned.
786 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
787 (SIZE_MAX, UINT_MAX): New macros.
788 (quotearg_n_options): Abort if N is negative.
789 Avoid overflow check on hosts where size_t is 64 bits and int
790 is 32 bits, as overflow is impossible there.
791 Fix off-by-one typo that caused unnecessary reallocation.
792
793 2001-11-29 Paul Eggert <eggert@twinsun.com>
794

796
797 * doc/bison.texinfo (Bison Parser): Discuss system headers
798 and their effect on the user name space.
799
800 * src/bison.simple:
801 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
802 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
803 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
804
805 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
806 on user names when possible.
807
808 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
809 Simplify test for whather <alloca.h> exists.
810
811 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
812
813 (<stdio.h>): Include if YYDEBUG.
814
815 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
816 ! defined (yyoverflow) && ! defined (yymemcpy).
817
818 (yymemcpy, yyparse): Rename local variables as needed so that
819 they all begin with 'yy'.
820
821 (yystrlen, yystpcpy): New functions.
822
823 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
824 All uses changed.
825
826 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
827 instead of relying on string.h functions. Use YYSTACK_ALLOC
828 and YYSTACK_FREE instead of malloc and free.
829
830 2001-11-30 Akim Demaille <akim@epita.fr>
831
832 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
833 before their first uses.
834 (YYBISON, YYPURE): Move to the top of the output.
835
836 2001-11-30 Akim Demaille <akim@epita.fr>
837
838 * tests/reduce.at (Useless Nonterminals): Fix.
839
840 2001-11-30 Akim Demaille <akim@epita.fr>
841
842 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
843 if body instead of `;' to pacify GCC's warnings.
844
845 2001-11-30 Akim Demaille <akim@epita.fr>
846
847 Instead of mapping the LHS of unused rules to -1, keep the LHS
848 valid, but flag the rules as invalid.
849
850 * src/gram.h (rule_t): `useful' is a new member.
851 * src/print.c (print_grammar): Adjust.
852 * src/derives.c (set_derives): Likewise.
853 * src/reader.c (packgram, reduce_output): Likewise.
854 * src/reduce.c (reduce_grammar_tables): Likewise.
855 * tests/reduce.at (Underivable Rules, Useless Rules): New.
856
857 2001-11-30 Akim Demaille <akim@epita.fr>
858
859 * src/reduce.c (reduce_output): Formatting changes.
860 * src/print.c (print_results, print_grammar): Likewise.
861 * tests/regression.at (Rule Line Numbers)
862 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
863
864 2001-11-30 Akim Demaille <akim@epita.fr>
865
866 * src/reduce.c (nonterminals_reduce): Instead of throwing away
867 useless nonterminals, move them at the end of the symbol arrays.
868 (reduce_output): Adjust.
869 * tests/reduce.at (Useless Nonterminals): Adjust.
870
871 2001-11-30 Akim Demaille <akim@epita.fr>
872
873 * src/reduce.c: Various comment/formatting changes.
874 (nonterminals_reduce): New, extracted from...
875 (reduce_grammar_tables): here.
876 (reduce_grammar): Call nonterminals_reduce.
877
878 2001-11-29 Paul Eggert <eggert@twinsun.com>
879
880 * src/bison.simple (YYSTACK_REALLOC): Remove.
881 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
882 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
883 New macros.
884 (union yyalloc): New type.
885 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
886 an arbitrary restriction on hosts where size_t is wider than int.
887
888 (yyparse): Don't dump core if alloca or malloc fails; instead, report
889 a parser stack overflow. Allocate just one block of memory for all
890 three stacks, instead of allocating three blocks; this typically is
891 faster and reduces fragmentation.
892
893 Do not limit the number of items in the stack to a value that fits
894 in 'int', as this is an arbitrary limit on hosts with 64-bit
895 size_t and 32-bit int.
896
897 2001-11-29 Marc Autret <autret_m@epita.fr>
898
899 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
900 of defining YYERROR_VERBOSE.

908 * src/lex.c (literalchar): Become not static.
909
910 2001-11-28 Marc Autret <autret_m@epita.fr>
911
912 * src/output.h: And put its extern declaration here.
913 * src/output.c (error_verbose): Define here.
914 (prepare): Echo name modification.
915 * src/getargs.h: Clean its extern declaration.
916 * src/getargs.c (error_verbose_flag): Remove.
917 (getargs): Remove case 'e'.
918 * src/options.c (option_table): 'error-verbose' is now seen as simple
919 percent option.
920 Include output.h.
921
922 * src/reader.c (read_declarations): Remove case tok_include.
923 (parse_include_decl): Remove.
924 * src/lex.h (token_t): Remove tok_include.

936
937 * src/bison.simple: Fix debug.
938 [YYERROR_VERBOSE]: Re-integrate as an internal macro.
939
940 2001-11-28 Akim Demaille <akim@epita.fr>
941
942 * src/LR0.c (shifts_new): New.
943 (save_shifts, insert_start_shift, augment_automaton): Use it.
944
945 2001-11-28 Akim Demaille <akim@epita.fr>
946
947 * src/closure.c (closure): `b' and `ruleno' denote the same value:
948 keep ruleno only.
949
950 2001-11-28 Akim Demaille <akim@epita.fr>
951
952 * src/closure.c (closure): Instead of looping over word in array
953 then bits in words, loop over bits in array.
954
955 2001-11-28 Akim Demaille <akim@epita.fr>
956
957 * src/closure.c (closure): No longer optimize the special case
958 where all the bits of `ruleset[r]' are set to 0, to make the code
959 clearer.
960
961 2001-11-28 Akim Demaille <akim@epita.fr>
962
963 * src/closure.c (closure): `r' and `c' are new variables, used to
964 de-obfuscate accesses to RULESET and CORE.
965
966 2001-11-28 Akim Demaille <akim@epita.fr>
967
968 * src/reduce.c (reduce_print): Use ngettext.

1327 use abs. path to find config.h.
1328 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

2751 instead of returning a token.
2752 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
2753 * src/reader.c (read_declarations): Adjust.
2754 * src/files.c (open_files): Don't call `compute_base_names', don't
2755 compute `attrsfile' since they depend upon data which might be
2756 *in* the input file now.
2757 (output_files): Do it here.
2758 * src/output.c (output_headers): Document the fact that this patch
2759 introduces a guaranteed SEGV for semantic parsers.
2760 * doc/bison.texinfo: Document them.

2786 2000-12-20 Akim Demaille <akim@epita.fr>
2787
2788 * src/files.c (open_files): Actually the `.output' file is based
2789 on the short_base_name, not base_name.
2790 * tests/suite.at (Checking output file names): Adjust.
2791
2792 2000-12-20 Akim Demaille <akim@epita.fr>

2816
2817 * src/files.c (strsuffix): New.
2818 (stringappend): Be just like strcat but allocate.
2819 (base_names): Eve out from open_files.
2820 Try to simplify the rather hairy computation of base_name and
2821 short_base_name.

2824

2852 skeleton.
2853 * src/reader.c (read_declarations): When %semantic_parser, open

2860
2861 2000-12-19 Akim Demaille <akim@epita.fr>
2862
2863 * src/files.c (open_files): Yipee! We no longer need all the code
2864 looking for `/tmp' since we have no tmp file.
2865
2866 2000-12-19 Akim Demaille <akim@epita.fr>
2867
2868 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

2896 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
2897 prevents type checking.
2898 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
2899 cast the value to (void *): assigning a `foo *' to a `void *'
2900 variable is valid.
2901 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
2902 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

2917 2000-11-17 Akim Demaille <akim@epita.fr>
2918
2919 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
2920 macros.

2945 * src/output.c (output): Remove useless variables.
2946 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
2947 argument `data' for consistency with the prototypes.
2948 Qualify it `const'.
2949 (obstack_copy, obstack_copy0): Rename the second argument as
2950 `address' for consistency. Qualify it `const'.
2951 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
2952 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
2953 `const' their input argument (`data' or `address').
2954 Adjust the corresponding macros to include `const' in casts.

2957

2963
2964 For some reason, this was not applied.
2965
2966 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

2975
2976 Don't use `atexit'.
2977
2978 * src/files.c (obstack_save): New function.
2979 (done): Rename as...
2980 (output_files): this.
2981 Use `obstack_save'.
2982 * src/main.c (main): Don't use `atexit' to register `done', since
2983 it no longer has to remove tmp files, just call `output_files'
2984 when there are no errors.
2985
2986 2000-11-02 Akim Demaille <akim@epita.fr>
2987

2995

3007
3008 Change each use of `fattrs' into a use of `attrs_obstack'.

3046
3047 2000-10-16 Akim Demaille <akim@epita.fr>
3048
3049 * src/lex.c (read_typename): New function.
3050 (lex): Use it.
3051 * src/reader.c (copy_dollar): Likewise.
3052
3053 2000-10-16 Akim Demaille <akim@epita.fr>
3054
3055 * src/reader.c (copy_comment2): Expect the input stream to be on
3056 the `/' which is suspected to open a comment, instead of being
3057 called after `//' or `/*' was read.
3058 (copy_comment, copy_definition, parse_union_decl, copy_action)
3059 (copy_guard): Adjust.
3060
3061 2000-10-16 Akim Demaille <akim@epita.fr>
3062
3063 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

3067
3068 * src/reader.c (copy_dollar): New function.

3078
3079 2000-10-04 Akim Demaille <akim@epita.fr>
3080
3081 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
3082
3083 2000-10-04 Akim Demaille <akim@epita.fr>
3084
3085 * doc/bison.texinfo: Various typos spotted by Neil Booth.
3086
3087 2000-10-04 Akim Demaille <akim@epita.fr>
3088
3089 When a literal string is used to define two different tokens,
3090 `bison -v' segfaults.
3091 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3092
3093 * tests/regression.m4: New file.
3094 Include the core of the sample provided by Piotr Gackiewicz.

3096 properly.
3097
3098 2000-10-04 Akim Demaille <akim@epita.fr>
3099
3100 * src/reader.c (parse_expect_decl): Keep `count' within the size
3101 of `buffer'.
3102 From Neil Booth.
3103
3104 2000-10-02 Paul Eggert <eggert@twinsun.com>
3105
3106 * bison.s1 (yyparse): Assign the default value
3107 unconditionally, to avoid a GCC warning and make the parser a
3108 tad smaller.
3109
3110 2000-10-02 Akim Demaille <akim@epita.fr>
3111
3112 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3113 options.
3114
3115 2000-10-02 Akim Demaille <akim@epita.fr>
3116
3117 * src/derives.c, src/print.c, src/reduce.c: To ease the
3118 translation, move some `\n' out of the translated strings.
3119
3120 2000-10-02 Akim Demaille <akim@epita.fr>
3121
3122 The location tracking mechanism is precious for parse error
3123 messages. Nevertheless, it is enabled only when `@n' is used in
3124 the grammar, which is a different issue (you can use it in error
3125 message, but not in the grammar per se). Therefore, there should
3126 be another means to enable it.
3127
3128 * src/getargs.c (getargs): Support `--locations'.
3129 (usage): Report it.
3130 * src/getargs.h (locationsflag): Export it.
3131 * src/lex.c (percent_table): Support `%locations'.
3132 * src/reader.c (yylsp_needed): Remove this variable, now replaced
3133 with `locationsflag'.
3134 * doc/bison.texinfo: Document `--locations' and `%locations'.
3135 Sort the options.
3136 * tests/calc.m4: Test it.
3137
3138 For regularity of the names, replace each
3139 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3140 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3141 In addition replace each `flag' with `_flag'.
3142
3143 2000-10-02 Akim Demaille <akim@epita.fr>
3144
3145 Also test parse error messages, including with YYERROR_VERBOSE.
3146
3147 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3148 associative).
3149 Use it to check the computations.
3150 Use it to check `nonassoc' is honored.
3151 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3152 `--yyerror-verbose'.
3153 (_AT_CHECK_CALC): Adjust to this option.
3154 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3155
3156 2000-10-02 Akim Demaille <akim@epita.fr>
3157
3158 Test also `--verbose', `--defines' and `--name-prefix'. Testing
3159 the latter demonstrates a flaw in the handling of non debugging
3160 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3161 was used in order to simplify:
3162
3163 #if YYDEBUG
3164 if (yydebug)
3165 {
3166 ...
3167 }
3168 #endif
3169
3170 into
3171
3172 if (yydebug)
3173 {
3174 ...
3175 }
3176
3177 unfortunately this leads to a CPP conflict when
3178 `--name-prefix=foo' is used since it produces `#define yydebug
3179 foodebug'.
3180
3181 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3182 (YYDPRINTF): New macro.
3183 Spread its use.
3184 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3185 the bison options.
3186 Also test `--verbose', `--defines' and `--name-prefix'.
3187
3188 2000-10-02 Akim Demaille <akim@epita.fr>
3189
3190 Improve the readability of the produced parsers.
3191
3192 * src/bison.s1: Formatting changes.
3193 Improve the comment related to the `$' mark.
3194 (yydefault): Don't fall through to `yyresume': `goto' there.
3195 * src/output.c (output_parser): When the `$' is met, skip the end
3196 of its line.
3197 New variable, `number_of_dollar_signs', to check there's exactly
3198 one `$' in the parser skeleton.
3199
3200 2000-10-02 Akim Demaille <akim@epita.fr>
3201
3202 * lib/xstrdup.c: New file, from the fileutils.
3203 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3204 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3205 instead of strlen + xmalloc + strcpy.
3206 * src/symtab.c (copys): Remove, use xstrdup instead.
3207
3208 2000-10-02 Akim Demaille <akim@epita.fr>
3209
3210 * src/gram.h (associativity): New enum type which replaces the
3211 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3212 `right_assoc', `left_assoc' and `non_assoc'.
3213 Adjust all dependencies.
3214 * src/reader.c: Formatting changes.
3215 (LTYPESTR): Don't define it, use it as a literal in
3216 `reader_output_yylsp'.
3217 * src/symtab.h (symbol_class): New enum type which replaces the
3218 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3219 `sunknown', `stoken and `snterm'.
3220
3221 2000-10-02 Akim Demaille <akim@epita.fr>
3222
3223 * src/getargs.c (fixed_outfiles): Rename as...
3224 (yaccflag): for consistency and accuracy.
3225 Adjust dependencies.
3226
3227 2000-10-02 Akim Demaille <akim@epita.fr>
3228
3229 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3230 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
3231 difficult and introduced a lot of core dump. It turns out that
3232 Bison used an implementation of `xmalloc' based on `calloc', and
3233 at various places it does depend upon the initialization to 0. I
3234 have not tried to isolate the pertinent places, and all the former
3235 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
3236 someone should address this issue.
3237
3238 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3239 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
3240 files.
3241 Adjust dependencies.
3242 * src/warshall.h: New file.
3243 Propagate.
3244
3245 2000-10-02 Akim Demaille <akim@epita.fr>
3246
3247 Various anti-`extern in *.c' changes.
3248
3249 * src/system.h: Include `assert.h'.
3250
3251 2000-10-02 Akim Demaille <akim@epita.fr>
3252
3253 * src/state.h (nstates, final_state, first_state, first_shift)
3254 (first_reduction): Move their exportation from here...
3255 * src/LR0.h: to here.
3256 Adjust dependencies.
3257 * src/getargs.c (statisticsflag): New variable.
3258 Add support for `--statistics'.
3259 Adjust dependencies.
3260
3261 Remove a lot of now useless `extern' statements in most files.
3262
3263 2000-10-02 Akim Demaille <akim@epita.fr>
3264
3265 * src/LR0.h: New file.
3266 Propagate its use.
3267
3268 2000-10-02 Akim Demaille <akim@epita.fr>

3337 2000-10-02 Akim Demaille <akim@epita.fr>
3338
3339 `user_toknums' is output as a `short[]' in `output.c', while it is

3383 inclusion.
3384 Don't define PARAMS.
3385 * src/system.h: Define PARAMS.
3386 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3387 purpose of config.h. system.h must not try to fix wrong
3388 definitions in config.h.
3389
3390 2000-09-20 Akim Demaille <akim@epita.fr>
3391

3524 * Makefile.am (SUBDIRS): Adjust.

3553
3554 On syntax errors, report the token on which we choked.

3604 2000-03-17 Akim Demaille <akim@epita.fr>
3605
3606 Change the handling of @s so that they behave exactly like $s.
3607 There is now a pseudo variable @$ (readble and writable), location
3608 of the lhs of the rule (by default ranging from the location of
3609 the first symbol of the rhs, to the location of the last symbol,
3610 or, if the rhs is empty, YYLLOC).

3643
3644 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
3645 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3646 One `#if YYDEBUG' remains, since it uses variables which are
3647 defined only if `YYDEBUG != 0'.

3649 2000-03-16 Akim Demaille <akim@epita.fr>
3650

3687 * m4/Makefile.am (EXTRA_DIST): New variable.
3688 * m4/gettext.m4: New file, from the fileutils.

4319 New function.
4320 (readgram): Use `#if 0' around code that accepted %command
4321 inside grammar rules: The documentation doesn't allow it,
4322 and it will fail since the %command processors scan for the next %.
4323 (parse_token_decl): Extended the %token
4324 declaration to allow a multi-character symbol as an alias.
4325 (parse_thong_decl): New function.
4326 (read_declarations): Added %thong declarations.
4327 (read_declarations): Handle NOOP to deal with allowing
4328 % declarations as another means to specify the flags.
4329 (readgram): Allow %prec prior to semantics embedded in a rule.
4330 (skip_to_char, read_declarations, copy_definition)
4331 (parse_token_decl, parse_start_decl, parse_type_decl)

4333 (get_type_name, copy_guard, copy_action, readgram)
4334 (get_type, packsymbols): Revised most error messages.
4335 Changed `fatal' to `warnxxx' to avoid aborting for error.
4336 Revised and use multiple warnxxx functions to avoid using VARARGS1.
4337 (read_declarations): Improve the error message for
4338 an invalid character. Do not abort.
4339 (read_declarations, copy_guard, copy_action): Use
4340 printable_version to avoid unprintable characters in printed output.
4341 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
4342 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
4343 Allow the type of a non-terminal can be given
4344 more than once, as long as all specifications give the same type.
4345
4346 * src/output.c:
4347 (output_headers, output_trailers, output, output_gram)
4348 (output_rule_data): Implement noparserflag variable.
4349 Implement toknumflag variable.
4350 (output): Call reader_output_yylsp to output LTYPESTR.
4351
4352 * src/main.c (main):
4353 If reader sees an error, don't process the grammar.
4354 (fatals): Updated to not use VARARGS1.
4355 (printable_version, int_to_string, warn, warni, warns, warnss)

4358 * src/lex.h:
4359 Added THONG and NOOP for alias processing.
4360 Added SETOPT for the new code that allows setting options with %flags.
4361
4362 * src/lex.c:
4363 Include getopt.h. Add some extern decls.
4364 (safegetc): New function to deal with EOF gracefully.
4365 (literalchar); new function to deal with reading \ escapes.
4366 (lex): Use literalchar.
4367 (lex): Implemented "..." tokens.
4368 (literalchar, lex, parse_percent_token): Made tokenbuffer
4369 always contain the token. This includes growing the token
4370 buffer while reading an integer.
4371 (parse_percent_token): Replaced if-else statement with percent_table.
4372 (parse_percent_token): Added % declarations as another
4373 way to specify the flags -n, -l, and -r. Also added hooks for
4374 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4375 major changes to files.c.
4376 (lex) Retain in the incoming stream a character following
4377 an incorrect '/'.
4378 (skip_white_space, lex): Revised most error messages
4379 and changed fatal to warn to avoid aborting.

4383
4384 * src/files.c (openfiles, open_extra_files, done):
