8
9 2001-12-16 Marc Autret <autret_m@epita.fr>
10
11 * src/output.c (actions_output): Fix. When we use %no-lines,
12 there is one less line per action.
13
14 2001-12-16 Marc Autret <autret_m@epita.fr>
15
16 * src/bison.simple: Remove a useless #line directive.
17 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18 * src/output.c (get_lines_number): New.
19 (output_parser): Adjust, now takes care about the lines of a
20 output muscles.
21 Fix line numbering.
22 (actions_output): Computes the number of lines taken by actions.
23 (output_master_parser): Insert new skeleton which is the name of
24 the output parser file name.
25
26 2001-12-15 Marc Autret <autret_m@epita.fr>
27
28 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
29
30 2001-12-15 Marc Autret <autret_m@epita.fr>
31
32 * src/output.c (output_gram): Keep track of the hairy one.
33
34 2001-12-15 Akim Demaille <akim@epita.fr>
35
36 Make `make distcheck' work.
37
38 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
39 system.h which uses libgettext.h.
40
41 2001-12-15 Akim Demaille <akim@epita.fr>
42
43 * src/nullable.c (set_nullable): Useless rules must be skipped,
44 otherwise, since we range over their symbols, we might look at a
45 nonterminal which no longer ``exists'', i.e., it is not counted in
46 `nvars', hence we overflow our arrays.
47
48 2001-12-15 Akim Demaille <akim@epita.fr>
49
50 The header can also be produced directly, without any obstack!
51 Yahoo!
52
53 * src/files.c, src/files.h (defines_obstack): Remove.
54 (compute_header_macro): Global.
55 (defines_obstack_save): Remove.
56 * src/reader.c (parse_union_decl): No longer output to
57 defines_obstack: its content can be found in the `stype' muscle
58 anyway.
59 (output_token_translations): Merge into...
60 (symbols_output): this.
61 Rename as...
62 (symbols_save): this.
63 (reader): Adjust.
64 * src/output.c (header_output): New.
65 (output): Call it.
66
67 2001-12-15 Akim Demaille <akim@epita.fr>
68
69 * src/reader.c (parse_union_decl): Instead of handling two obstack
70 simultaneously, use one to define the `stype' muscle, and use the
71 value of the latter to fill defines_obstack.
72 (copy_comment): Remove.
73 (copy_comment2): Work for a single obstack.
74 Rename as...
75 (copy_comment): this.
76
77 2001-12-15 Akim Demaille <akim@epita.fr>
78
79 * src/lex.c, src/lex.h (xgetc): No longer static.
80 * src/reader.c (parse_union_decl): Revamp.
81
82 2001-12-15 Akim Demaille <akim@epita.fr>
83
84 Still making progress in separating Bison into (i) input, (ii)
85 process, (iii) output: now we can directly output the parser file
86 without using table_obstack at all.
87
88 * src/files.c, src/files.h (table_obstack): Bye bye.
89 (parser_file_name): New.
90 * src/files.c (compute_output_file_names): Compute it.
91 * src/output.c (actions_output, output_parser)
92 (output_master_parser): To a file instead of an obstack.
93
94 2001-12-15 Akim Demaille <akim@epita.fr>
95
96 Attach actions to rules, instead of pre-outputting them to
97 actions_obstack.
98
99 * src/gram.h (rule_t): action and action_line are new members.
100 * src/reader.c (symbol_list): Likewise.
101 (copy_action): Save the actions within the rule.
102 (packgram): Save them in rule_table.
103 * src/output.c (actions_output): New.
104 (output_parser): Use it on `%%actions'.
105 (output_rule_data): Don't free rule_table.
106 (output): Do it.
107 (prepare): Don't save the `action' muscle.
108 * src/bison.simple: s/%%action/%%actions/.
109
110 2001-12-15 Akim Demaille <akim@epita.fr>
111
112 * src/reader.c (copy_action): When --yacc, don't append a `;'
113 to the user action: let it fail if lacking.
114 Suggested by Aharon Robbins and Tom Tromey.
115
116 2001-12-14 Akim Demaille <akim@epita.fr>
117
118 * src/lex.c (literalchar): Simply return the char you decoded, non
119 longer mess around with obstacks and int pointers.
120 Adjust all callers.
121
122 2001-12-14 Akim Demaille <akim@epita.fr>
123
124 * src/lex.c (literalchar): Don't escape the special characters,
125 just decode them, and keep them as char (before, eol was output as
126 the 2 char string `\n' etc.).
127 * src/output.c (output_rule_data): Use quotearg to output the
128 token strings.
129
130 2001-12-13 Paul Eggert <eggert@twinsun.com>
131
132 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
133 Do not infringe on the global user namespace when using C++.
134 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
135 All uses of `fprintf' and `stderr' changed.
136
137 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
138
139 2001-12-13 Akim Demaille <akim@epita.fr>
140
141 The computation of nullable is broken: it doesn't handle empty
142 RHS's properly.
143
144 * tests/torture.at (GNU AWK Grammar): New.
145 * tests/sets.at (Nullable): New.
146 * src/nullable.c (set_nullable): Instead of blindly looping over
147 `ritems', loop over the rules, and then over their rhs's.
148
149 Work around Autotest bugs.
150
151 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
152 frame, because Autotest understand lines starting with a `+' as
153 traces from the shell. Then, they are not processed properly.
154 Admittedly an Autotest bug, but we don't have time to wait for
155 Autotest to catch up.
156 * tests/regression.at (Broken Closure): Adjust to the new table
157 frames.
158 Move to...
159 * tests/sets.at: here.
160
161 2001-12-13 Akim Demaille <akim@epita.fr>
162
163 * src/closure.c (closure): Use nrules instead of playing tricks
164 with BITS_PER_WORD.
165
166 2001-12-13 Akim Demaille <akim@epita.fr>
167
168 * src/print.c (print_actions): Output the handling of `$' as the
169 traces do: shifting the token EOF. Before EOF was treated as a
170 nonterminal.
171 * tests/regression.at: Adjust some tests.
172 * src/print_graph.c (print_core): Complete the set of items via
173 closure. The next-to-final and final states are still unsatisfying,
174 but that's to be addressed elsewhere.
175 No longer output the rule numbers, but do output the state number.
176 A single loop for the shifts + gotos is enough, but picked a
177 distinct color for each.
178 (print_graph): Initialize and finalize closure.
179
180 2001-12-13 Akim Demaille <akim@epita.fr>
181
182 * src/reader.c (readgram): Remove dead code, an strip useless
183 braces.
184 (get_type): Remove, unused.
185
186 2001-12-12 Akim Demaille <akim@epita.fr>
187
188 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
189 on that of lib/error.c.
190
191 2001-12-12 Akim Demaille <akim@epita.fr>
192
193 Some hosts don't like `/' in includes.
194
195 * src/system.h: Include libgettext.h without qualifying the path.
196 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
197 $(top_srcdir).
198
199 2001-12-11 Marc Autret <autret_m@epita.fr>
200
201 * src/output.c (output_parser): Remove useless muscle.
202
203 2001-12-11 Marc Autret <autret_m@epita.fr>
204
205 * src/bison.simple: Remove #line just before %%epilogue. It
206 is now handled in ...
207 * src/reader.c (read_additionnal_code): Add the output of a
208 #line for the epilogue.
209
210 2001-12-10 Marc Autret <autret_m@epita.fr>
211
212 * src/reader.c (copy_definition): Re-use CPP-outed code which
213 replace precedent remove.
214 * src/bison.simple: Remove #line before %%prologue because
215 %%input-line is wrong at this time.
216
217 2001-12-10 Marc Autret <autret_m@epita.fr>
218
219 * src/reader.c (symbols_output): Clean up.
220 * src/output.c (output_gram, output): Clean up.
221
222 2001-12-10 Akim Demaille <akim@epita.fr>
223
224 * src/lalr.c (initialize_lookaheads): New. Extracted from...
225 * src/LR0.c (set_state_table): here.
226 * src/lalr.c (lalr): Call it.
227
228 2001-12-10 Akim Demaille <akim@epita.fr>
229
230 * src/state.h (shifts): Remove the `number' member: shifts are
231 attached to state, hence no longer need to be labelled with a
232 state number.
233
234 2001-12-10 Akim Demaille <akim@epita.fr>
235
236 Now that states have a complete set of members, the linked list of
237 shifts is useless: just fill directly the state's shifts member.
238
239 * src/state.h (shifts): Remove the `next' member.
240 * src/LR0.c (first_state, last_state): Remove.
241 Adjust the callers.
242 (augment_automaton): Don't look for the shifts that must be added
243 a shift on EOF: it is those of the state we looked for! But now,
244 since shifts are attached, it is no longer needed to looking
245 merely by its id: its number.
246
247 2001-12-10 Akim Demaille <akim@epita.fr>
248
249 * src/LR0.c (augment_automaton): Better variable locality.
250 Remove an impossible branch: if there is a state corresponding to
251 the start symbol being shifted, then there is shift for the start
252 symbol from the initial state.
253
254 2001-12-10 Akim Demaille <akim@epita.fr>
255
256 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
257 only when appropriate: when insert_start_shifting_state' is not
258 invoked.
259 * tests/regression.at (Rule Line Numbers): Adjust.
260
261 2001-12-10 Akim Demaille <akim@epita.fr>
262
263 * src/LR0.c (augment_automaton): Now that all states have shifts,
264 merge the two cases addition shifts to the initial state.
265
266 2001-12-10 Akim Demaille <akim@epita.fr>
267
268 * src/lalr.c (set_state_table): Move to...
269 * src/LR0.c: here.
270 * src/lalr.c (lalr): Don't call it...
271 * src/LR0.c (generate_states): do it.
272 * src/LR0.h (first_state): Remove, only the table is used.
273
274 2001-12-10 Akim Demaille <akim@epita.fr>
275
276 * src/LR0.h (first_shift, first_reduction): Remove.
277 * src/lalr.c: Don't use first_shift: find shifts through the
278 states.
279
280 2001-12-10 Akim Demaille <akim@epita.fr>
281
282 * src/LR0.c: Attach shifts to states as soon as they are
283 computed.
284 * src/lalr.c (set_state_table): Instead of assigning shifts to
285 state, just assert that the mapping was properly done.
286
287 2001-12-10 Akim Demaille <akim@epita.fr>
288
289 * src/LR0.c (insert_start_shift): Rename as...
290 (insert_start_shifting_state): this.
291 (insert_eof_shifting_state, insert_accepting_state): New.
292 (augment_automaton): Adjust.
293 Better locality of the variables.
294 When looking if the start_symbol is shifted from the initial
295 state, using `while (... symbol != start_symbol ...)' sounds
296 better than `while (... symbol < start_symbol ...)': If fail
297 to see how the order between symbols could be relevant!
298
299 2001-12-10 Akim Demaille <akim@epita.fr>
300
301 * src/getargs.h: Don't declare `spec_name_prefix' and
302 `spec_file_prefix', declared by src/files.h.
303 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
304 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
305 * src/output.c (prepare): Adjust.
306 * src/reader.c (symbols_output): Likewise.
307 * src/vmsgetargs.c: Vaguely adjust, but who cares?
308
309 2001-12-10 Akim Demaille <akim@epita.fr>
310
311 * src/muscle_tab.c (muscle_init): NULL is a better default than
312 `"0"'.
313
314 2001-12-10 Akim Demaille <akim@epita.fr>
315
316 * src/reader.c (reader): Calling symbols_output once is enough.
317
318 2001-12-10 Akim Demaille <akim@epita.fr>
319
320 Now that states have a complete set of members, the linked list of
321 reductions is useless: just fill directly the state's reductions
322 member.
323
324 * src/state.h (struct reductions): Remove member `number' and
325 `next'.
326 * src/LR0.c (first_reduction, last_reduction): Remove.
327 (save_reductions): Don't link the new reductions, store them in
328 this_state.
329 * src/lalr.c (set_state_table): No need to attach reductions to
330 states, it's already done.
331 * src/output.c (output_actions): No longer free the shifts, then
332 the reductions, then the states: free all the states and their
333 members.
334
335 2001-12-10 Akim Demaille <akim@epita.fr>
336
337 * src/options.c (OPTN, DRTV, BOTH): New.
338 (option_table): Use them.
339
340 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
341 the job of system.h.
342 * src/options.c: Don't include stdio.h and xalloc.h for the same
343 reasons.
344
345 2001-12-10 Akim Demaille <akim@epita.fr>
346
347 * src/output.c (output, prepare): Make sure the values of the
348 muscles `action' and `prologue' are 0-terminated.
349
350 2001-12-10 Akim Demaille <akim@epita.fr>
351
352 Clean up GCC warnings.
353
354 * src/reader.c (copy_action): `buf' is not used.
355 (parse_skel_decl): Be static.
356 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
357 * src/options.h (create_long_option_table): Have a real prototype.
358 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
359 (hash_delete_at): Return const void *.
360 Adjust casts to preserve the const.
361
362 2001-12-10 Akim Demaille <akim@epita.fr>
363
364 * configure.in: Require 2.52g.
365 M4 is not needed, but AUTOM4TE is.
366 * m4/m4.m4: Remove.
367 * tests/Makefile.am: Adjust.
368
369 2001-12-10 Akim Demaille <akim@epita.fr>
370
371 One structure for states is enough, even though theoretically
372 there are LR(0) states and LALR(1) states.
373
374 * src/lalr.h (state_t): Remove.
375 (state_table): Be state_t **, not state_t *.
376 * src/state.h (core, CORE_ALLOC): Rename as...
377 (state_t, STATE_ALLOC): this.
378 Add the LALR(1) members: shifts, reductions, errs.
379 * src/LR0.c (state_table): Rename as...
380 (state_hash): this, to avoid name clashes with the global
381 `state_table'.
382 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
383 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
384
385 2001-12-10 Akim Demaille <akim@epita.fr>
386
387 Bison dumps core on bash.y.
388 Reported by Pascal Bart.
389
390 * src/warshall.c (bitmatrix_print): New.
391 (TC): Use it.
392 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
393 j must be the outer loop.
394 * tests/regression.at (Broken Closure): New.
395
396 2001-12-05 Akim Demaille <akim@epita.fr>
397
398 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
399 its argument.
400 Reported by Peter Hámorský.
401
402 2001-12-05 Akim Demaille <akim@epita.fr>
403
404 * src/conflicts.c (err_table): Remove.
405 (resolve_sr_conflict): Adjust.
406 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
407 Rename as...
408 (state_t.reductions, state_t.shifts): this.
409
410 2001-12-05 Akim Demaille <akim@epita.fr>
411
412 * src/reduce.c (reduce_grammar_tables): No longer disable the
413 removal of useless rules via CPP but via `if (0)', so that the
414 compiler still check the code is valid.
415 For instance, it should have noticed `rline' no longer exists: use
416 the `line' member of rule_t.
417 * src/gram.c (dummy, rline): Remove, unused.
418
419 2001-12-05 Akim Demaille <akim@epita.fr>
420
421 * src/output.c (pack_vector): Use assert, not berror.
422 * src/main.c (berror): Remove, unused.
423
424 2001-12-05 Akim Demaille <akim@epita.fr>
425
426 New experimental feature: if --verbose --trace output all the
427 items of a state, not only its kernel.
428
429 * src/print.c (print_core): If `trace_flag', then invoke closure
430 before outputting the items of the state (print_core is no longer
431 a correct name them).
432 (print_results): Invoke new_closure/free_closure if needed.
433
434 2001-12-05 Akim Demaille <akim@epita.fr>
435
436 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
437 * src/closure.c, src/closure.h (itemsetsize): Rename as...
438 (nitemset): for consistency with the rest of the project.
439
440 2001-12-05 Akim Demaille <akim@epita.fr>
441
442 * src/closure.c (print_closure): Improve.
443 (closure): Use it for printing input and output.
444
445 2001-12-05 Akim Demaille <akim@epita.fr>
446
447 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
448 indexed by nonterminals.
449
450 2001-12-05 Akim Demaille <akim@epita.fr>
451
452 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
453 what it was!).
454 * src/warshall.h: Remove accidental duplication of the content.
455
456 2001-12-05 Akim Demaille <akim@epita.fr>
457
458 * src/closure.c (set_fderives): De-obfuscate.
459
460 2001-12-05 Akim Demaille <akim@epita.fr>
461
462 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
463
464 2001-12-05 Akim Demaille <akim@epita.fr>
465
466 * src/closure.c (set_firsts): De-obfuscate.
467
468 2001-12-05 Akim Demaille <akim@epita.fr>
469
470 * src/output.c (action_row): De-obfuscate
471 using the good o' techniques: arrays not pointers, variable
472 locality, BITISSET, RESETBIT etc.
473
474 2001-12-05 Akim Demaille <akim@epita.fr>
475
476 Pessimize the code to simplify it: from now on, all the states
477 have a valid SHIFTS, which NSHIFTS is possibly 0.
478
479 * src/LR0.c (shifts_new): Be global and move to..
480 * src/state.c, src/state.h: here.
481 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
482 * src/print_graph: Adjust.
483
484 2001-12-05 Akim Demaille <akim@epita.fr>
485
486 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
487 * src/conflicts.c: Use it.

490
491 2001-12-05 Akim Demaille <akim@epita.fr>
492
493 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
494 using the good o' techniques: arrays not pointers, variable
495 locality, BITISSET, RESETBIT etc.
496
497 2001-12-05 Akim Demaille <akim@epita.fr>
498
499 * src/state.h (SHIFT_SYMBOL): New.

501
502 2001-12-05 Akim Demaille <akim@epita.fr>
503
504 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
505 (print_reductions): De-obfuscate using the good o' techniques:
506 arrays not pointers, variable locality, BITISSET.
507
508 2001-12-05 Akim Demaille <akim@epita.fr>
509
510 * src/conflicts.c (print_reductions): Arrays, not pointers.

530
531 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
532 * src/lalr.c: Use them.
533
534 2001-12-05 Akim Demaille <akim@epita.fr>
535
536 * src/LR0.c (augment_automaton): Formatting changes.
537 Better variable locality.
538
539 2001-12-05 Akim Demaille <akim@epita.fr>
540
541 * src/lalr.c (matrix_print): New.
542 (transpose): Use it.
543 Use arrays instead of pointers.
544
545 2001-12-05 Akim Demaille <akim@epita.fr>
546
547 * src/lalr.c (maxrhs): Move to...
548 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
549 * src/lalr.c (build_relations): Adjust.
550
551 2001-12-05 Akim Demaille <akim@epita.fr>
552
553 * src/lalr.c (transpose): Free the memory allocated to the
554 argument, as it is replaced by the results by the unique caller.
555 (build_relations): Merely invoke transpose: it handles the memory
556 deallocation.
557 Improve variable locality.
558 Avoid variables used as mere abbreviations.
559 (compute_lookaheads): Use arrays instead of pointers.
560
561 2001-12-05 Akim Demaille <akim@epita.fr>
562

565
566 2001-12-05 Akim Demaille <akim@epita.fr>
567
568 * src/derives.c (print_derives): Display the ruleno.
569 * src/lalr.c (initialize_F, transpose): Better variable locality
570 to improve readability.

572
573 2001-12-05 Akim Demaille <akim@epita.fr>
574
575 * src/lalr.c (traverse): Use arrays instead of pointers.
576
577 2001-12-05 Akim Demaille <akim@epita.fr>
578
579 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
580 the handling of squeue.
581 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
582
583 2001-12-05 Akim Demaille <akim@epita.fr>
584
585 Because useless nonterminals are now kept alive (instead of being
586 `destroyed'), we now sometimes examine them, and store information
587 related to them. Hence we need to know their number, and adjust
588 memory allocations.
589
590 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
591 static.
592 * src/LR0.c (allocate_itemsets): The memory allocated to
593 `symbol_count' was used for two different purpose: once to count
594 the number of occurrences of each symbol, and later reassigned to
595 `shift_symbol', containing the symbol that can be shifted from a
596 given state.
597 Deobfuscate, i.e., allocate, use and free `symbol_count' here
598 only, and...
599 (new_itemsets): Allocate `shift_symbol' here.
600 (allocate_itemsets): symbol_count includes useless nonterminals.
601 Make room for them.
602 (free_storage): Use `free', not `XFREE', for pointers that cannot
603 be null.
604
605 2001-12-05 Akim Demaille <akim@epita.fr>
606
607 * src/nullable.c (set_nullable): Deobfuscate the handling of
608 ritem.
609 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
610
611 2001-12-05 Akim Demaille <akim@epita.fr>
612
613 * src/gram.c, src/gram.h (ritem_print): New.
614 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
615 (This useless function was defined only to work around VMS linkers
616 that can't handle compilation units with variables only).
617 * src/reduce.c (dump_grammar): Use it to trace the construction of
618 ritem.
619
620 2001-12-04 Paul Eggert <eggert@twinsun.com>
621
622 * src/bison.simple (union yyalloc): Change member names
623 to be the same as the stack names.
624 (yyparse): yyptr is now union yyalloc *, not char *.
625 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
626 and may generate better code on some machines.
627 (yystpcpy): Use prototype if __STDC__ is defined, not just
628 if __cplusplus is defined.
629
630 2001-11-30 Akim Demaille <akim@epita.fr>
631
632 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
633 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
634 Gettext doesn't compile cleanly, and dies with -Werror.
635 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
636 Include WARNING_CFLAGS here.
637 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
638 before being defined.
639
640 2001-11-27 Paul Eggert <eggert@twinsun.com>
641
642 * lib/quotearg.h (quotearg_n, quotearg_n_style):
643 First arg is int, not unsigned.
644 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
645 (SIZE_MAX, UINT_MAX): New macros.
646 (quotearg_n_options): Abort if N is negative.
647 Avoid overflow check on hosts where size_t is 64 bits and int
648 is 32 bits, as overflow is impossible there.
649 Fix off-by-one typo that caused unnecessary reallocation.
650
651 2001-11-29 Paul Eggert <eggert@twinsun.com>
652

657
658 * src/bison.simple:
659 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
660 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
661 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
662
663 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
664 on user names when possible.
665
666 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
667 Simplify test for whather <alloca.h> exists.
668
669 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
670
671 (<stdio.h>): Include if YYDEBUG.
672
673 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
674 ! defined (yyoverflow) && ! defined (yymemcpy).
675
676 (yymemcpy, yyparse): Rename local variables as needed so that
677 they all begin with 'yy'.
678
679 (yystrlen, yystpcpy): New functions.
680
681 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
682 All uses changed.
683
684 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
685 instead of relying on string.h functions. Use YYSTACK_ALLOC
686 and YYSTACK_FREE instead of malloc and free.
687
688 2001-11-30 Akim Demaille <akim@epita.fr>
689
690 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

698 2001-11-30 Akim Demaille <akim@epita.fr>
699
700 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
701 if body instead of `;' to pacify GCC's warnings.
702
703 2001-11-30 Akim Demaille <akim@epita.fr>
704
705 Instead of mapping the LHS of unused rules to -1, keep the LHS
706 valid, but flag the rules as invalid.
707
708 * src/gram.h (rule_t): `useful' is a new member.
709 * src/print.c (print_grammar): Adjust.
710 * src/derives.c (set_derives): Likewise.
711 * src/reader.c (packgram, reduce_output): Likewise.
712 * src/reduce.c (reduce_grammar_tables): Likewise.
713 * tests/reduce.at (Underivable Rules, Useless Rules): New.

725 useless nonterminals, move them at the end of the symbol arrays.
726 (reduce_output): Adjust.

728
729 2001-11-30 Akim Demaille <akim@epita.fr>

739 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
740 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
741 New macros.
742 (union yyalloc): New type.
743 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
744 an arbitrary restriction on hosts where size_t is wider than int.
745
746 (yyparse): Don't dump core if alloca or malloc fails; instead, report
747 a parser stack overflow. Allocate just one block of memory for all
748 three stacks, instead of allocating three blocks; this typically is
749 faster and reduces fragmentation.
750
751 Do not limit the number of items in the stack to a value that fits
752 in 'int', as this is an arbitrary limit on hosts with 64-bit
753 size_t and 32-bit int.
754
755 2001-11-29 Marc Autret <autret_m@epita.fr>
756

802
803 2001-11-28 Akim Demaille <akim@epita.fr>
804
805 * src/closure.c (closure): `b' and `ruleno' denote the same value:
806 keep ruleno only.
807
808 2001-11-28 Akim Demaille <akim@epita.fr>
809
810 * src/closure.c (closure): Instead of looping over word in array

814
815 * src/closure.c (closure): No longer optimize the special case

819 2001-11-28 Akim Demaille <akim@epita.fr>
820
821 * src/closure.c (closure): `r' and `c' are new variables, used to

834
835 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
836 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
837 as all tags are free'ed afterwards.

841
842 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

1209 * src/lex.c (parse_percent_token): Replace equal_offset with

2586
2587 2001-01-19 Akim Demaille <akim@epita.fr>
2588
2589 * src/lex.h: Rename all the tokens:
2590 s/\bENDFILE\b/tok_eof/g;

2609 instead of returning a token.
2610 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
2611 * src/reader.c (read_declarations): Adjust.
2612 * src/files.c (open_files): Don't call `compute_base_names', don't
2613 compute `attrsfile' since they depend upon data which might be
2614 *in* the input file now.
2615 (output_files): Do it here.
2616 * src/output.c (output_headers): Document the fact that this patch
2617 introduces a guaranteed SEGV for semantic parsers.
2618 * doc/bison.texinfo: Document them.

2643
2644 2000-12-20 Akim Demaille <akim@epita.fr>
2645
2646 * src/files.c (open_files): Actually the `.output' file is based

2676 (stringappend): Be just like strcat but allocate.
2677 (base_names): Eve out from open_files.
2678 Try to simplify the rather hairy computation of base_name and
2679 short_base_name.
2680 (open_files): Use it.
2681 * tests/suite.at (Checking output file names): New test.
2682

2718
2719 2000-12-19 Akim Demaille <akim@epita.fr>
2720
2721 * src/files.c (open_files): Yipee! We no longer need all the code

2723
2724 2000-12-19 Akim Demaille <akim@epita.fr>
2725

2755 prevents type checking.
2756 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

2805 argument `data' for consistency with the prototypes.
2806 Qualify it `const'.
2807 (obstack_copy, obstack_copy0): Rename the second argument as
2808 `address' for consistency. Qualify it `const'.

2835
2836 * src/files.c (obstack_save): New function.
2837 (done): Rename as...
2838 (output_files): this.
2839 Use `obstack_save'.
2840 * src/main.c (main): Don't use `atexit' to register `done', since
2841 it no longer has to remove tmp files, just call `output_files'
2842 when there are no errors.
2843
2844 2000-11-02 Akim Demaille <akim@epita.fr>
2845

2864 2000-11-01 Akim Demaille <akim@epita.fr>
2865
2866 Change each use of `fattrs' into a use of `attrs_obstack'.
2867
2868 * src/reader.c (copy_at): Typo: s/yylloc/yyloc/.
2869 * src/files.c (fattrs): Remove.

2906
2907 * src/lex.c (read_typename): New function.
2908 (lex): Use it.
2909 * src/reader.c (copy_dollar): Likewise.
2910
2911 2000-10-16 Akim Demaille <akim@epita.fr>
2912
2913 * src/reader.c (copy_comment2): Expect the input stream to be on
2914 the `/' which is suspected to open a comment, instead of being
2915 called after `//' or `/*' was read.
2916 (copy_comment, copy_definition, parse_union_decl, copy_action)
2917 (copy_guard): Adjust.
2918
2919 2000-10-16 Akim Demaille <akim@epita.fr>
2920
2921 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

2942
2943 * doc/bison.texinfo: Various typos spotted by Neil Booth.
2944
2945 2000-10-04 Akim Demaille <akim@epita.fr>
2946
2947 When a literal string is used to define two different tokens,
2948 `bison -v' segfaults.
2949 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
2950

2955
2956 2000-10-04 Akim Demaille <akim@epita.fr>
2957
2958 * src/reader.c (parse_expect_decl): Keep `count' within the size
2959 of `buffer'.
2960 From Neil Booth.
2961
2962 2000-10-02 Paul Eggert <eggert@twinsun.com>
2963
2964 * bison.s1 (yyparse): Assign the default value
2965 unconditionally, to avoid a GCC warning and make the parser a
2966 tad smaller.
2967
2968 2000-10-02 Akim Demaille <akim@epita.fr>
2969
2970 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
2971 options.
2972
2973 2000-10-02 Akim Demaille <akim@epita.fr>
2974
2975 * src/derives.c, src/print.c, src/reduce.c: To ease the
2976 translation, move some `\n' out of the translated strings.
2977
2978 2000-10-02 Akim Demaille <akim@epita.fr>
2979
2980 The location tracking mechanism is precious for parse error
2981 messages. Nevertheless, it is enabled only when `@n' is used in
2982 the grammar, which is a different issue (you can use it in error
2983 message, but not in the grammar per se). Therefore, there should
2984 be another means to enable it.
2985
2986 * src/getargs.c (getargs): Support `--locations'.
2987 (usage): Report it.
2988 * src/getargs.h (locationsflag): Export it.
2989 * src/lex.c (percent_table): Support `%locations'.
2990 * src/reader.c (yylsp_needed): Remove this variable, now replaced
2991 with `locationsflag'.
2992 * doc/bison.texinfo: Document `--locations' and `%locations'.
2993 Sort the options.
2994 * tests/calc.m4: Test it.
2995
2996 For regularity of the names, replace each
2997 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2998 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2999 In addition replace each `flag' with `_flag'.
3000
3001 2000-10-02 Akim Demaille <akim@epita.fr>
3002
3003 Also test parse error messages, including with YYERROR_VERBOSE.
3004
3005 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3006 associative).
3007 Use it to check the computations.
3008 Use it to check `nonassoc' is honored.
3009 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3010 `--yyerror-verbose'.
3011 (_AT_CHECK_CALC): Adjust to this option.
3012 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3013
3014 2000-10-02 Akim Demaille <akim@epita.fr>
3015
3016 Test also `--verbose', `--defines' and `--name-prefix'. Testing
3017 the latter demonstrates a flaw in the handling of non debugging
3018 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3019 was used in order to simplify:
3020
3021 #if YYDEBUG
3022 if (yydebug)
3023 {
3024 ...
3025 }
3026 #endif
3027
3028 into
3029
3030 if (yydebug)
3031 {
3032 ...
3033 }
3034
3035 unfortunately this leads to a CPP conflict when
3036 `--name-prefix=foo' is used since it produces `#define yydebug
3037 foodebug'.
3038
3039 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3040 (YYDPRINTF): New macro.
3041 Spread its use.
3042 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3043 the bison options.
3044 Also test `--verbose', `--defines' and `--name-prefix'.
3045
3046 2000-10-02 Akim Demaille <akim@epita.fr>
3047
3048 Improve the readability of the produced parsers.
3049
3050 * src/bison.s1: Formatting changes.
3051 Improve the comment related to the `$' mark.
3052 (yydefault): Don't fall through to `yyresume': `goto' there.
3053 * src/output.c (output_parser): When the `$' is met, skip the end
3054 of its line.
3055 New variable, `number_of_dollar_signs', to check there's exactly
3056 one `$' in the parser skeleton.
3057
3058 2000-10-02 Akim Demaille <akim@epita.fr>
3059
3060 * lib/xstrdup.c: New file, from the fileutils.
3061 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3062 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3063 instead of strlen + xmalloc + strcpy.
3064 * src/symtab.c (copys): Remove, use xstrdup instead.
3065
3066 2000-10-02 Akim Demaille <akim@epita.fr>
3067
3068 * src/gram.h (associativity): New enum type which replaces the
3069 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3070 `right_assoc', `left_assoc' and `non_assoc'.
3071 Adjust all dependencies.
3072 * src/reader.c: Formatting changes.
3073 (LTYPESTR): Don't define it, use it as a literal in
3074 `reader_output_yylsp'.
3075 * src/symtab.h (symbol_class): New enum type which replaces the
3076 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3077 `sunknown', `stoken and `snterm'.
3078
3079 2000-10-02 Akim Demaille <akim@epita.fr>
3080
3081 * src/getargs.c (fixed_outfiles): Rename as...
3082 (yaccflag): for consistency and accuracy.
3083 Adjust dependencies.
3084
3085 2000-10-02 Akim Demaille <akim@epita.fr>
3086
3087 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3088 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
3089 difficult and introduced a lot of core dump. It turns out that
3090 Bison used an implementation of `xmalloc' based on `calloc', and
3091 at various places it does depend upon the initialization to 0. I
3092 have not tried to isolate the pertinent places, and all the former
3093 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
3094 someone should address this issue.
3095
3096 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3097 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

3104
3105 Various anti-`extern in *.c' changes.
3106
3107 * src/system.h: Include `assert.h'.
3108
3109 2000-10-02 Akim Demaille <akim@epita.fr>
3110
3111 * src/state.h (nstates, final_state, first_state, first_shift)
3112 (first_reduction): Move their exportation from here...
3113 * src/LR0.h: to here.
3114 Adjust dependencies.
3115 * src/getargs.c (statisticsflag): New variable.
3116 Add support for `--statistics'.
3117 Adjust dependencies.
3118
3119 Remove a lot of now useless `extern' statements in most files.
3120
3121 2000-10-02 Akim Demaille <akim@epita.fr>

3134
3135 2000-10-02 Akim Demaille <akim@epita.fr>
3136
3137 * src/conflicts.c (conflict_report): New function.
3138 (conflict_log, verbose_conflict_log): Replace with...
3139 (print_conflicts): this function.
3140 Adjust dependencies.
3141 * src/conflicts.h: New file.
3142 Propagate its inclusion.
3143
3144 2000-10-02 Akim Demaille <akim@epita.fr>
3145
3146 * src/nullable.h: New file.
3147 Propagate its inclusion.

3177 * src/lex.h: Prototype `lex.c' exported functions.
3178 * src/reader.c: Adjust.
3179 * src/lex.c: Formatting changes.
3180 (safegetc): Rename as...
3181 (xgetc): this.
3182
3183 2000-10-02 Akim Demaille <akim@epita.fr>
3184
3185 * src/lalr.h: New file.
3186 Propagate its inclusion instead of prototypes and `extern'.

3188
3189 2000-10-02 Akim Demaille <akim@epita.fr>
3190
3191 * src/output.c (token_actions): Introduce a temporary array,
3192 YYDEFACT, that makes it possible for this function to use
3193 output_short_table.
3194
3195 2000-10-02 Akim Demaille <akim@epita.fr>
3196
3197 `user_toknums' is output as a `short[]' in `output.c', while it is
3198 defined as a `int[]' in `reader.c'. For consistency with the
3199 other output tables, `user_toknums' is now defined as a table of
3200 shorts.
3201
3202 * src/reader.c (user_toknums): Be a short table instead of an int
3203 table.
3204 Adjust dependencies.
3205
3206 Factor the short table outputs.
3207
3208 * src/output.c (output_short_table): New function.
3209 * src/output.c (output_gram, output_stos, output_rule_data)
3210 (output_base, output_table, output_check): Use it.
3211
3212 2000-10-02 Akim Demaille <akim@epita.fr>
3213
3214 * src/output.c (output): Topological sort of the functions, in
3215 order to get rid of the `static' prototypes.
3216 No longer use `register'.
3217 * src/output.h: New file.
3218 Propagate its inclusion in files explicitly prototyping functions
3219 from output.c.
3220

3237
3238 2000-09-20 Akim Demaille <akim@epita.fr>
3239
3240 * src/acconfig.h: Don't protect config.h against multiple
3241 inclusion.
3242 Don't define PARAMS.
3243 * src/system.h: Define PARAMS.
3244 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3245 purpose of config.h. system.h must not try to fix wrong
3246 definitions in config.h.
3247
3248 2000-09-20 Akim Demaille <akim@epita.fr>
3249
3250 * src/derives.h: New file.

3270 * src/getargs.h: New file.
3271 Let all `extern' declarations about getargs.c be replaced with
3272 inclusion of `getargs.h'.
3273 * src/Makefile.am (noinst_HEADERS): Adjust.
3274
3275 * tests/calc.m4 (yyin): Be initialized in main, not on the global
3276 scope.

3465 There is now a pseudo variable @$ (readble and writable), location
3466 of the lhs of the rule (by default ranging from the location of
3467 the first symbol of the rhs, to the location of the last symbol,
3468 or, if the rhs is empty, YYLLOC).

3503 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

3508

4231 way to specify the flags -n, -l, and -r. Also added hooks for
