PE		 122002-01-29 Paul Eggert <eggert@twinsun.com>
13
14 * src/bison.simple (YYSIZE_T): Do not define merely because
15 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
16 On some platforms, <alloca.h> does not declare YYSTD (size_t).

AD		 182002-01-27 Akim Demaille <akim@epita.fr>
19
20 Fix `%nonassoc and eof'.
21
22 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
23 which were not properly copied! Replace
24 memcpy (res->errs, src->errs, src->nerrs);
25 with
26 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
27 !!!
28 * tests/regression.at (%nonassoc and eof): Adjust to newest
29 Autotest: `.' is not in the PATH.
30
318b76e9
AD		 312002-01-27 Akim Demaille <akim@epita.fr>
32
33 * tests/sets.at (AT_EXTRACT_SETS): New.

AD		 372002-01-26 Akim Demaille <akim@epita.fr>
38
39 * tests/actions.at, tests/calc.at, tests/headers.at,
40 * tests/torture.at: Adjust to the newest Autotest which no longer
41 forces `.' in the PATH.

50 Bison dumps core when trying to complain about broken input files.
51 Reported by Cris van Pelt.
52
53 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
54 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
55 into...
56 (Invalid inputs): Strengthen: exercise parse_percent_token.
57

RA		 582002-01-24 Robert Anisko <robert.anisko@epita.fr>
59
60 * src/Makefile.am: Add bison.c++.

74
5e5d5415
MA		 752002-01-20 Marc Autret <marc@gnu.org>
76
77 * tests/output.at: New test.
78 * src/files.c (compute_base_names): Don't map extensions when
79 the YACC flag is set, use defaults.
80 Reported by Evgeny Stambulchik.
81
44ea3fbd
MA		 822002-01-20 Marc Autret <marc@gnu.org>
83
bb0146c2 84 * src/system.h: Need to define __attribute__ away for non-GCC
44ea3fbd
MA		 85 compilers as well (i.e. the vendor C compiler).
86 Suggested by Albert Chin-A-Young.
87
338963d1
TVH		 882002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
89
90 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
91 canonical definition.
92 * src/system.h: Use the canonical definition for PARAMS (avoids
93 a conflict with the macro from lib/hash.h).
94
c57b2479
AD		 952002-01-11 Akim Demaille <akim@epita.fr>
96
97 * configure.in: Use AC_FUNC_STRNLEN.
d9e9746c 98 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.

AD		 1002002-01-09 Akim Demaille <akim@epita.fr>
101
102 * src/files.c, src/files.h (output_infix): New.
103 (tab_extension): Remove.
104 (compute_base_names): Compute the former, drop the latter.
105 * src/output.c (prepare): Insert the muscles `output-infix', and
106 `output-suffix'.
107 * src/parse-skel.y (string, string.1): New.
108 (section.header): Use it.
109 (section.yacc): Remove.
110 (prefix): Remove too.
111 * src/scan-skel.l: Adjust.

113
cae60122
AD		 1142002-01-09 Akim Demaille <akim@epita.fr>
115
116 * configure.in (WERROR_CFLAGS): Compute it.
117 * src/Makefile.am (CFLAGS): Pass it.
118 * tests/atlocal.in (CFLAGS): Idem.
119 * src/files.c: Fix a few warnings.
120 (get_extension_index): Remove, unused.
121
ae404801
AD		 1222002-01-08 Akim Demaille <akim@epita.fr>
123
124 * src/getargs.c (AS_FILE_NAME): New.
125 (getargs): Use it to convert DOSish file names.
126 * src/files.c (base_name): Rename as full_base_name to avoid
127 clashes with `base_name ()'.
128 (filename_split): New.
129 (compute_base_names): N-th rewrite, using filename_split.
130
22312b71
AD		 1312002-01-08 Akim Demaille <akim@epita.fr>
132
133 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
134 New, stolen from the Fileutils 4.1.
135 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
136 * configure.in: Check for the presence of memrchr, and of its
137 prototype.
138
a67cef01
TVH		 1392002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
140
141 * lib/hash.h (__P): Added definition for this macro.
142 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
143 BUILT_SOURCES, to ensure they are generated first.
144 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
145 %error-verbose to allow bootstrapping with bison 1.30x.
146
2b25d624
AD		 1472002-01-06 Akim Demaille <akim@epita.fr>
148
149 * src/reader.c (parse_braces): Don't fetch the next char, the
150 convention is to fetch on entry.
151 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
152 'switch' without a following semicolon.
153 * tests/regression.at (braces parsing): New.
154
3460813b
AD		 1552002-01-06 Akim Demaille <akim@epita.fr>
156
157 Bison is dead wrong in its RR conflict reports.
158
159 * tests/torture.at (GNU Cim Grammar): New.
160 * src/conflicts.c (count_rr_conflicts): Fix.
161
73784c64
AD		 1622002-01-06 Akim Demaille <akim@epita.fr>
163
164 Creating package.m4 from configure.ac causes too many problems.
165
166 * tests/Makefile.am (package.m4): Create it by hand,
167 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
168
25d81090
AD		 1692002-01-06 Akim Demaille <akim@epita.fr>
170
171 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
172 skeleton.h.
173
a9b8959e
PE		 1742002-01-04 Paul Eggert <eggert@twinsun.com>
175
176 * doc/bison.texinfo (Debugging):
177 Remove YYSTDERR; it's no longer defined or used.
178 Also, s/cstdio.h/cstdio/.
179
25d81090
AD		 1802002-01-03 Akim Demaille <akim@epita.fr>
181
182 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
183
1109455c
AD		 1842002-01-03 Akim Demaille <akim@epita.fr>
185
186 * src/parse-skel.y (process_skeleton): Don't bind the parser's
187 tracing code to --trace, wait for a better --trace option, with
188 args.
189
7ea5e977
AD		 1902002-01-03 Akim Demaille <akim@epita.fr>
191
192 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
193 The ISO C++ standard is extremely clear about it: stderr is
194 considered a macro, not a regular symbol (see table 94 `Header
195 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
196 Therefore std:: does not apply to it. It still does with fprintf.
197 Also, s/cstdio.h/cstdio/.
198
fab5b110
AD		 1992002-01-03 Akim Demaille <akim@epita.fr>
200
201 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
202 for non system headers.
203
aed7fd9b
AD		 2042002-01-02 Akim Demaille <akim@epita.fr>
205
206 Equip the skeleton chain with location tracking, runtime trace,
207 pure parser and scanner.
208
209 * src/parse-skel.y: Request a pure parser, locations, and prefix
210 renaming.
211 (%union): Having several members with the same type does not help
212 type mismatches, simplify.
213 (YYPRINT, yyprint): New.
214 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
215 (skel_error): this.
216 Handle locations.
217 * src/scan-skel.l: Adjust to these changes.
218 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
219 (LOCATION_PRINT, skel_control_t): New.
220
24fad99e
AD		 2212001-12-30 Akim Demaille <akim@epita.fr>
222
223 * src/parse-skel.y: Get rid of the shift/reduce conflict:
224 replace `gb' with BLANKS.
225 * src/scan-skel.l: Adjust.
226
a4b36db4
AD		 2272001-12-30 Akim Demaille <akim@epita.fr>
228
229 * src/system.h: We don't need nor want bcopy.
230 Throw away MS-DOS crap: we don't need getpid.
231 * configure.in: We don't need strndup. It was even causing
232 problems: because Flex includes the headers *before* us,
233 _GNU_SOURCE is not defined by config.h, and therefore strndup was
234 not visible.
235 * lib/xstrndup.c: New.
236 * src/scan-skel.l: Use it.
237 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
238 * src/parse-skel.y: Use %directives instead of #defines.
239
1239777d
AD		 2402001-12-30 Akim Demaille <akim@epita.fr>
241
242 * src/skeleton.h: New.
243 * src/output.c (output_parser, output_master_parser): Remove, dead
244 code.
245 * src/output.h (get_lines_number, actions_output, guards_output)
246 (token_definitions_output): Prototype them.
247 * src/parse-skel.y: Add the license notice.
248 Include output.h and skeleton.h.
249 (process_skeleton): Returns void, and takes a single parameter.
250 * src/scan-skel.l: Add the license notice.
251 Include skeleton.h.
252 Don't use %option yylineno: it seems that then Flex imagines
253 REJECT has been used, and therefore it won't reallocate its
254 buffers (which makes no other sense to me than a bug). It results
255 in warnings for `unused: yy_flex_realloc'.
256
9b3add5b
RA		 2572001-12-30 Robert Anisko <robert.anisko@epita.fr>
258
259 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
260 (MUSCLE_INSERT_PREFIX): ...to there.
261 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
262 (MUSCLE_INSERT_PREFIX): Move from here...
263
264 * src/bison.hairy: Add a section directive. Put braces around muscle
265 names. This parser skeleton is still broken, but Bison should not
266 choke on a bad muscle 'syntax'.
267 * src/bison.simple: Add a section directive. Put braces around muscle
268 names.
269
270 * src/files.h (strsuffix, stringappend): Add declarations.
271 (tab_extension): Add declaration.
272 (short_base_name): Add declaration.
273
274 * src/files.c (strsuffix, stringappend): No longer static. These
275 functions are used in the skeleton parser.
276 (tab_extension): New.
277 (compute_base_names): Use the computations done in this function
fab5b110 278 to guess if the generated parsers should have '.tab' in their
9b3add5b
RA		 279 names.
280 (short_base_name): No longer static.
281
282 * src/output.c (output_skeleton): New.
283 (output): Disable call to output_master_parser, and give a try to
284 a new skeleton handling system.
285 (guards_output, actions_output): No longer static.
286 (token_definitions_output, get_lines_number): No longer static.
287
288 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
289
fab5b110 290 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
9b3add5b
RA		 291 parse-skel.y.
292
293 * src/parse-skel.y: New file.
294 * src/scan-skel.l: New file.
295
b5b61c61
AD		 2962001-12-29 Akim Demaille <akim@epita.fr>
297
298 %name-prefix is broken.
299
300 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
301 Adjust all dependencies.
302 * tests/headers.at (export YYLTYPE): Strengthen this test: use
303 %name-prefix.
304
305 Renaming yylval but not yylloc is not consistent. Now we do.
306
307 * src/bison.simple: Prefix yylloc if used.
308 * doc/bison.texinfo (Decl Summary): Document that.
309
8c9a50be
AD		 3102001-12-29 Akim Demaille <akim@epita.fr>
311
312 * doc/bison.texinfo: Promote `%long-directive' over
313 `%long_directive'.
314 Remove all references to fixed-output-files, yacc is enough.
315
d99361e6
AD		 3162001-12-29 Akim Demaille <akim@epita.fr>
317
318 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
319 user prologue. These are defaults.
320 * tests/actions.at (Mid-rule actions): Make sure the user can
321 define YYDEBUG and YYERROR_VERBOSE.
322
b9cecb91
AD		 3232001-12-29 Akim Demaille <akim@epita.fr>
324
325 * src/output.c (header_output): Don't forget to export YYLTYPE and
326 yylloc.
327 * tests/headers.at (export YYLTYPE): New, make sure it does.
328 * tests/regression.at (%union and --defines, Invalid CPP headers):
329 Move to...
330 * tests/headers.at: here.
331
aea13e97
AD		 3322001-12-29 Akim Demaille <akim@epita.fr>
333
334 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
335
931394cb
AD		 3362001-12-29 Akim Demaille <akim@epita.fr>
337
338 * tests/actions.at (Mid-rule actions): Output on a single line
339 instead of several.
340
704a47c4
AD		 3412001-12-29 Akim Demaille <akim@epita.fr>
342
343 * doc/bison.texinfo: Formatting changes.
344
091e20bb
AD		 3452001-12-29 Akim Demaille <akim@epita.fr>
346
347 Don't store the token defs in a muscle, just be ready to output it
348 on command. Now possible via `symbols'. Fixes a memory leak.
349
350 * src/output.c (token_definitions_output): New.
351 (output_parser, header_output): Use it.
352 * src/reader.c (symbols_save): Remove.
353
cce71710
AD		 3542001-12-29 Akim Demaille <akim@epita.fr>
355
356 * src/bison.simple: Do not provide a default for YYSTYPE and
357 YYLTYPE before the user's prologue. Otherwise it's hardly... a
358 default.
359
82c035a8
AD		 3602001-12-29 Akim Demaille <akim@epita.fr>
361
362 Mid-rule actions are simply... ignored!
363
364 * src/reader.c (readgram): Be sure to attach mid-rule actions to
365 the empty-rule associated to the dummy symbol, not to the host
366 rule.
367 * tests/actions.at (Mid-rule actions): New.
368
8419d367
AD		 3692001-12-29 Akim Demaille <akim@epita.fr>
370
371 Memory leak.
372
373 * src/reader.c (reader): Free grammar.
374
375d5806
AD		 3752001-12-29 Akim Demaille <akim@epita.fr>
376
377 Memory leak.
378
379 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
380 since it allocates it for each state, although only one is needed.
381 (allocate_storage): Do it here.
382
f51cb8ff
AD		 3832001-12-29 Akim Demaille <akim@epita.fr>
384
385 * src/options.h, src/options.c (create_long_option_table): Rename
386 as...
387 (long_option_table_new): this, with a clearer prototype.
388 (percent_table): Remove, unused,
389 * src/getargs.c (getargs): Adjust.
390
29e88316

394 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
395 as states.
396
b9f71f19
AD		 3972001-12-29 Akim Demaille <akim@epita.fr>
398
399 * src/lalr.c (build_relations): Rename `states' as `states1'.
400 Sorry, I don't understand exactly what it is, no better name...
401
1a2b5d37
AD		 4022001-12-29 Akim Demaille <akim@epita.fr>
403
404 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
405 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
406 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
407 as rules.
408

410
411 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
412 ago.
413
c03ae966
AD		 4142001-12-29 Akim Demaille <akim@epita.fr>
415
416 * src/reader.c, src/reader.h (user_toknums): Remove.
417 Adjust all users to use symbols[i]->user_token_number.
418
5a670b1e
AD		 4192001-12-29 Akim Demaille <akim@epita.fr>
420

422 Adjust all users to use symbols[i]->prec or ->assoc.
423
ad949da9

425
426 * src/reader.c, src/reader.h (tags): Remove.
427 Adjust all users to use symbols[i]->tag.
428
0e78e603
AD		 4292001-12-29 Akim Demaille <akim@epita.fr>
430
431 * src/gram.h, src/gram.c (symbols): New, similar to state_table
432 and rule_table.
433 * src/reader.c (packsymbols): Fill this table.
434 Drop sprec.
435 * src/conflicts.c (resolve_sr_conflict): Adjust.
436 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
437 single table.
438 Use symbols[i]->tag instead of tags[i].
439
213e640e
AD		 4402001-12-29 Akim Demaille <akim@epita.fr>
441
442 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
443 In addition, put a comment in there, to replace...
444 * tests/regression.at (%union and C comments): Remove.
445
e7b8bef1
AD		 4462001-12-29 Akim Demaille <akim@epita.fr>
447
448 * tests/regression.at (Web2c Actions): Blindly move the actual
449 output as expected output. The contents *seem* right to me, but I
450 can't pretend reading perfectly parser tables... Nonetheless, all
451 the other tests pass correctly, the table look OK, even though the
452 presence of `$axiom' is to be noted: AFAICS it is useless (but
453 harmless).

457 * src/reader.c (readgram): Don't add the rule 0 if there were no
458 rules read. In other words, add it _after_ having performed
459 grammar sanity checks.

476 Fix the `GAWK Grammar' failure.
477
478 * src/LR0.c (final_state): Initialize to -1 so that we do compute
479 the reductions of the first state which was mistakenly confused
480 with the final state because precisely final_state was initialized
481 to 0.
482 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
483 now noticed by Bison.
484 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does

AD		 5292001-12-27 Paul Eggert <eggert@twinsun.com>
530
531 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
532 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
533 Sparc, as they were causing more porting problems than the
534 (minor) performance improvement was worth.
535

542 Use -1 as separator, not 0.
543 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
544 Rely on -1 as separator in yyrhs, instead of 0.
545 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
546 twice `Now at end of input', therefore there are two lines less to
547 expect.

557 * src/LR0.c (new_state): Recognize the final state by the fact it
558 is reached by eoftoken.
559 (insert_start_shifting_state, insert_eof_shifting_state)
560 (insert_accepting_state, augment_automaton): Remove, since now
561 these states are automatically computed from the initial state.
562 (generate_states): Adjust.
563 * src/print.c: When reporting a rule number to the user, substract
564 1, so that the axiom rule is rule 0, and the first user rule is 1.
565 * src/reduce.c: Likewise.
566 * src/print_graph.c (print_core): For the time being, just as for
567 the report, depend upon --trace-flags to dump the full set of
568 items.
569 * src/reader.c (readgram): Once the grammar read, insert the rule
570 0: `$axiom: START-SYMBOL $'.
571 * tests/set.at: Adjust: rule 0 is now displayed, and since the
572 number of the states has changed (the final state is no longer
573 necessarily the last), catch up.

577 Try to make the use of the eoftoken valid. Given that its value
578 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
579 is used instead of > 0 where appropriate, (ii), depend upon nritems
580 instead of the 0-sentinel.
581
582 * src/gram.h, src/gram.c (nritems): New.
583 Expected to be duplication of nitems, but for the time being...
584 * src/reader.c (packgram): Assert nritems and nitems are equal.
585 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.

593 * src/main.c (main): If there are complains after grammar
594 reductions, then output the report anyway if requested, then die.
595 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
596 * src/reader.c (eoftoken): New.
597 (parse_token_decl): If the token being defined has value `0', it
598 is the eoftoken.
599 (packsymbols): No longer hack `tags' to insert `$' by hand.
600 Be sure to preserve the value of the eoftoken.
601 (reader): Make sure eoftoken is defined.
602 Initialize nsyms to 0: now eoftoken is created just like the others.
603 * src/print.c (print_grammar): Don't special case the eof token.
604 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
605 lie anyway, albeit pleasant.
606 * tests/calc.at: Exercise error messages with eoftoken.
607 Change the grammar so that empty input is invalid.
608 Adjust expectations.
609 When yyungeting, be sure to use a valid yylloc: use last_yylloc.

694 * src/reader.c (symbol_list): `guard' and `guard_line' are new
695 members.
696 (symbol_list_new): Adjust.
697 (copy_action): action_line is the first line, not the last.
698 (copy_guard): Just as for actions, store the `action' only, not
699 the switch/case/break flesh.
700 Don't parse the user action that might follow the guard, let...
701 (readgram): do it, i.e., now, there can be an action after a
702 guard.
703 In other words the guard is just explicitly optional.
704 (packgram): Adjust.
705 * src/output.c (guards_output): New.

707 (output): Also free the guard and attrs obstacks.
708 * src/files.c, src/files.h (obstack_save): Remove.
709 (output_files): Remove.
710 As a result, if one needs the former `.act' file, using an
711 appropriate skeleton which requires actions and guards is now
712 required.
713 * src/main.c (main): Adjust.
714 * tests/semantic.at: New.

745 integer when referring to a state.
746 As much as possible, depend upon nlookaheads, instead of the
747 `lookaheadsp' member of the following state (since lookaheads of
748 successive states are successive, the difference between state n + 1
749 and n served as the number of lookaheads for state n).

906 * src/nullable.c (set_nullable): Useless rules must be skipped,
907 otherwise, since we range over their symbols, we might look at a
908 nonterminal which no longer ``exists'', i.e., it is not counted in

1004 The computation of nullable is broken: it doesn't handle empty
1005 RHS's properly.
1006
1007 * tests/torture.at (GNU AWK Grammar): New.
1008 * tests/sets.at (Nullable): New.
1009 * src/nullable.c (set_nullable): Instead of blindly looping over
1010 `ritems', loop over the rules, and then over their rhs's.
1011
1012 Work around Autotest bugs.
1013
1014 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1015 frame, because Autotest understand lines starting with a `+' as
1016 traces from the shell. Then, they are not processed properly.
1017 Admittedly an Autotest bug, but we don't have time to wait for
1018 Autotest to catch up.

1031 * src/print.c (print_actions): Output the handling of `$' as the
1032 traces do: shifting the token EOF. Before EOF was treated as a
1033 nonterminal.
1034 * tests/regression.at: Adjust some tests.
1035 * src/print_graph.c (print_core): Complete the set of items via
1036 closure. The next-to-final and final states are still unsatisfying,
1037 but that's to be addressed elsewhere.
1038 No longer output the rule numbers, but do output the state number.
1039 A single loop for the shifts + gotos is enough, but picked a
1040 distinct color for each.
1041 (print_graph): Initialize and finalize closure.

1099 Now that states have a complete set of members, the linked list of

1104 Adjust the callers.
1105 (augment_automaton): Don't look for the shifts that must be added
1106 a shift on EOF: it is those of the state we looked for! But now,

1108 merely by its id: its number.

1157 When looking if the start_symbol is shifted from the initial
1158 state, using `while (... symbol != start_symbol ...)' sounds
