2
3 * src/bison.simple (YYSIZE_T): Do not define merely because
4 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
5 On some platforms, <alloca.h> does not declare YYSTD (size_t).

8
9 Fix `%nonassoc and eof'.
10
11 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
12 which were not properly copied! Replace
13 memcpy (res->errs, src->errs, src->nerrs);
14 with
15 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
16 !!!
17 * tests/regression.at (%nonassoc and eof): Adjust to newest
18 Autotest: `.' is not in the PATH.
19
318b76e9
AD		 202002-01-27 Akim Demaille <akim@epita.fr>
21
22 * tests/sets.at (AT_EXTRACT_SETS): New.
23 (Nullable): Use it.
24 (Firsts): New.

AD		 262002-01-26 Akim Demaille <akim@epita.fr>
27
28 * tests/actions.at, tests/calc.at, tests/headers.at,
29 * tests/torture.at: Adjust to the newest Autotest which no longer
30 forces `.' in the PATH.

39 Bison dumps core when trying to complain about broken input files.
40 Reported by Cris van Pelt.
41
42 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
43 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
44 into...
45 (Invalid inputs): Strengthen: exercise parse_percent_token.

5e5d5415
MA		 642002-01-20 Marc Autret <marc@gnu.org>
65
66 * tests/output.at: New test.
67 * src/files.c (compute_base_names): Don't map extensions when
68 the YACC flag is set, use defaults.
69 Reported by Evgeny Stambulchik.
70

MA		 712002-01-20 Marc Autret <marc@gnu.org>
72
bb0146c2 73 * src/system.h: Need to define __attribute__ away for non-GCC
44ea3fbd
MA		 74 compilers as well (i.e. the vendor C compiler).
75 Suggested by Albert Chin-A-Young.
76
338963d1
TVH		 772002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
78
79 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
80 canonical definition.
81 * src/system.h: Use the canonical definition for PARAMS (avoids
82 a conflict with the macro from lib/hash.h).
83

AD		 842002-01-11 Akim Demaille <akim@epita.fr>
85
86 * configure.in: Use AC_FUNC_STRNLEN.

AD		 892002-01-09 Akim Demaille <akim@epita.fr>
90
91 * src/files.c, src/files.h (output_infix): New.
92 (tab_extension): Remove.
93 (compute_base_names): Compute the former, drop the latter.
94 * src/output.c (prepare): Insert the muscles `output-infix', and
95 `output-suffix'.

97 (section.header): Use it.
98 (section.yacc): Remove.
99 (prefix): Remove too.
100 * src/scan-skel.l: Adjust.
101 * src/bison.simple, src/bison.hairy: Adjust.

cae60122
AD		 1032002-01-09 Akim Demaille <akim@epita.fr>
104
105 * configure.in (WERROR_CFLAGS): Compute it.
106 * src/Makefile.am (CFLAGS): Pass it.
107 * tests/atlocal.in (CFLAGS): Idem.
108 * src/files.c: Fix a few warnings.
109 (get_extension_index): Remove, unused.
110
ae404801
AD		 1112002-01-08 Akim Demaille <akim@epita.fr>
112
113 * src/getargs.c (AS_FILE_NAME): New.
114 (getargs): Use it to convert DOSish file names.
115 * src/files.c (base_name): Rename as full_base_name to avoid
116 clashes with `base_name ()'.
117 (filename_split): New.
118 (compute_base_names): N-th rewrite, using filename_split.
119
22312b71
AD		 1202002-01-08 Akim Demaille <akim@epita.fr>
121
122 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
123 New, stolen from the Fileutils 4.1.
124 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
125 * configure.in: Check for the presence of memrchr, and of its
126 prototype.
127
a67cef01
TVH		 1282002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
129
130 * lib/hash.h (__P): Added definition for this macro.
131 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
132 BUILT_SOURCES, to ensure they are generated first.
133 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
134 %error-verbose to allow bootstrapping with bison 1.30x.
135
2b25d624
AD		 1362002-01-06 Akim Demaille <akim@epita.fr>
137
138 * src/reader.c (parse_braces): Don't fetch the next char, the
139 convention is to fetch on entry.
140 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
141 'switch' without a following semicolon.
142 * tests/regression.at (braces parsing): New.
143
3460813b
AD		 1442002-01-06 Akim Demaille <akim@epita.fr>
145
146 Bison is dead wrong in its RR conflict reports.
147
148 * tests/torture.at (GNU Cim Grammar): New.
149 * src/conflicts.c (count_rr_conflicts): Fix.
150
73784c64
AD		 1512002-01-06 Akim Demaille <akim@epita.fr>
152
153 Creating package.m4 from configure.ac causes too many problems.
154
155 * tests/Makefile.am (package.m4): Create it by hand,
156 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
157
25d81090
AD		 1582002-01-06 Akim Demaille <akim@epita.fr>
159
160 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
161 skeleton.h.
162
a9b8959e
PE		 1632002-01-04 Paul Eggert <eggert@twinsun.com>
164
165 * doc/bison.texinfo (Debugging):
166 Remove YYSTDERR; it's no longer defined or used.
167 Also, s/cstdio.h/cstdio/.
168
25d81090
AD		 1692002-01-03 Akim Demaille <akim@epita.fr>
170
171 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
172
1109455c
AD		 1732002-01-03 Akim Demaille <akim@epita.fr>
174
175 * src/parse-skel.y (process_skeleton): Don't bind the parser's
176 tracing code to --trace, wait for a better --trace option, with
177 args.
178
7ea5e977
AD		 1792002-01-03 Akim Demaille <akim@epita.fr>
180
181 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
182 The ISO C++ standard is extremely clear about it: stderr is
183 considered a macro, not a regular symbol (see table 94 `Header
184 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
185 Therefore std:: does not apply to it. It still does with fprintf.
186 Also, s/cstdio.h/cstdio/.
187
fab5b110
AD		 1882002-01-03 Akim Demaille <akim@epita.fr>
189
190 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
191 for non system headers.
192
aed7fd9b
AD		 1932002-01-02 Akim Demaille <akim@epita.fr>
194
195 Equip the skeleton chain with location tracking, runtime trace,
196 pure parser and scanner.
197
198 * src/parse-skel.y: Request a pure parser, locations, and prefix
199 renaming.
200 (%union): Having several members with the same type does not help
201 type mismatches, simplify.
202 (YYPRINT, yyprint): New.
203 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
204 (skel_error): this.
205 Handle locations.
206 * src/scan-skel.l: Adjust to these changes.
207 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
208 (LOCATION_PRINT, skel_control_t): New.
209
24fad99e
AD		 2102001-12-30 Akim Demaille <akim@epita.fr>
211
212 * src/parse-skel.y: Get rid of the shift/reduce conflict:
213 replace `gb' with BLANKS.
214 * src/scan-skel.l: Adjust.
215
a4b36db4
AD		 2162001-12-30 Akim Demaille <akim@epita.fr>
217
218 * src/system.h: We don't need nor want bcopy.
219 Throw away MS-DOS crap: we don't need getpid.
220 * configure.in: We don't need strndup. It was even causing
221 problems: because Flex includes the headers *before* us,
222 _GNU_SOURCE is not defined by config.h, and therefore strndup was
223 not visible.
224 * lib/xstrndup.c: New.
225 * src/scan-skel.l: Use it.
226 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
227 * src/parse-skel.y: Use %directives instead of #defines.
228
1239777d
AD		 2292001-12-30 Akim Demaille <akim@epita.fr>
230
231 * src/skeleton.h: New.
232 * src/output.c (output_parser, output_master_parser): Remove, dead
233 code.
234 * src/output.h (get_lines_number, actions_output, guards_output)
235 (token_definitions_output): Prototype them.
236 * src/parse-skel.y: Add the license notice.
237 Include output.h and skeleton.h.
238 (process_skeleton): Returns void, and takes a single parameter.
239 * src/scan-skel.l: Add the license notice.
240 Include skeleton.h.
241 Don't use %option yylineno: it seems that then Flex imagines
242 REJECT has been used, and therefore it won't reallocate its
243 buffers (which makes no other sense to me than a bug). It results
244 in warnings for `unused: yy_flex_realloc'.
245
9b3add5b
RA		 2462001-12-30 Robert Anisko <robert.anisko@epita.fr>
247
248 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
249 (MUSCLE_INSERT_PREFIX): ...to there.
250 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
251 (MUSCLE_INSERT_PREFIX): Move from here...
252
253 * src/bison.hairy: Add a section directive. Put braces around muscle
254 names. This parser skeleton is still broken, but Bison should not
255 choke on a bad muscle 'syntax'.
256 * src/bison.simple: Add a section directive. Put braces around muscle
257 names.
258
259 * src/files.h (strsuffix, stringappend): Add declarations.
260 (tab_extension): Add declaration.
261 (short_base_name): Add declaration.
262
263 * src/files.c (strsuffix, stringappend): No longer static. These
264 functions are used in the skeleton parser.
265 (tab_extension): New.
266 (compute_base_names): Use the computations done in this function
fab5b110 267 to guess if the generated parsers should have '.tab' in their
9b3add5b
RA		 268 names.
269 (short_base_name): No longer static.
270
271 * src/output.c (output_skeleton): New.
272 (output): Disable call to output_master_parser, and give a try to
273 a new skeleton handling system.
274 (guards_output, actions_output): No longer static.
275 (token_definitions_output, get_lines_number): No longer static.
276
277 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
278
fab5b110 279 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
9b3add5b
RA		 280 parse-skel.y.
281
282 * src/parse-skel.y: New file.
283 * src/scan-skel.l: New file.
284
b5b61c61
AD		 2852001-12-29 Akim Demaille <akim@epita.fr>
286
287 %name-prefix is broken.
288
289 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
290 Adjust all dependencies.
291 * tests/headers.at (export YYLTYPE): Strengthen this test: use
292 %name-prefix.
293
294 Renaming yylval but not yylloc is not consistent. Now we do.
295
296 * src/bison.simple: Prefix yylloc if used.
297 * doc/bison.texinfo (Decl Summary): Document that.
298
8c9a50be
AD		 2992001-12-29 Akim Demaille <akim@epita.fr>
300
301 * doc/bison.texinfo: Promote `%long-directive' over
302 `%long_directive'.
303 Remove all references to fixed-output-files, yacc is enough.
304
d99361e6
AD		 3052001-12-29 Akim Demaille <akim@epita.fr>
306
307 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
308 user prologue. These are defaults.
309 * tests/actions.at (Mid-rule actions): Make sure the user can
310 define YYDEBUG and YYERROR_VERBOSE.
311
b9cecb91
AD		 3122001-12-29 Akim Demaille <akim@epita.fr>
313
314 * src/output.c (header_output): Don't forget to export YYLTYPE and
315 yylloc.
316 * tests/headers.at (export YYLTYPE): New, make sure it does.
317 * tests/regression.at (%union and --defines, Invalid CPP headers):
318 Move to...
319 * tests/headers.at: here.
320
aea13e97
AD		 3212001-12-29 Akim Demaille <akim@epita.fr>
322
323 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
324
931394cb
AD		 3252001-12-29 Akim Demaille <akim@epita.fr>
326
327 * tests/actions.at (Mid-rule actions): Output on a single line
328 instead of several.
329
704a47c4
AD		 3302001-12-29 Akim Demaille <akim@epita.fr>
331
332 * doc/bison.texinfo: Formatting changes.
333
091e20bb
AD		 3342001-12-29 Akim Demaille <akim@epita.fr>
335
336 Don't store the token defs in a muscle, just be ready to output it
337 on command. Now possible via `symbols'. Fixes a memory leak.
338
339 * src/output.c (token_definitions_output): New.
340 (output_parser, header_output): Use it.
341 * src/reader.c (symbols_save): Remove.
342
cce71710
AD		 3432001-12-29 Akim Demaille <akim@epita.fr>
344
345 * src/bison.simple: Do not provide a default for YYSTYPE and
346 YYLTYPE before the user's prologue. Otherwise it's hardly... a
347 default.
348
82c035a8
AD		 3492001-12-29 Akim Demaille <akim@epita.fr>
350
351 Mid-rule actions are simply... ignored!
352
353 * src/reader.c (readgram): Be sure to attach mid-rule actions to
354 the empty-rule associated to the dummy symbol, not to the host
355 rule.
356 * tests/actions.at (Mid-rule actions): New.
357
8419d367
AD		 3582001-12-29 Akim Demaille <akim@epita.fr>
359
360 Memory leak.
361
362 * src/reader.c (reader): Free grammar.
363
375d5806
AD		 3642001-12-29 Akim Demaille <akim@epita.fr>
365
366 Memory leak.
367
368 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
369 since it allocates it for each state, although only one is needed.
370 (allocate_storage): Do it here.
371
f51cb8ff
AD		 3722001-12-29 Akim Demaille <akim@epita.fr>
373
374 * src/options.h, src/options.c (create_long_option_table): Rename
375 as...
376 (long_option_table_new): this, with a clearer prototype.
377 (percent_table): Remove, unused,
378 * src/getargs.c (getargs): Adjust.
379
29e88316
AD		 3802001-12-29 Akim Demaille <akim@epita.fr>
381
382 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
383 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
384 as states.
385
b9f71f19
AD		 3862001-12-29 Akim Demaille <akim@epita.fr>
387
388 * src/lalr.c (build_relations): Rename `states' as `states1'.
389 Sorry, I don't understand exactly what it is, no better name...
390
1a2b5d37
AD		 3912001-12-29 Akim Demaille <akim@epita.fr>
392
393 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
394 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
395 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
396 as rules.
397
1cca533e
AD		 3982001-12-29 Akim Demaille <akim@epita.fr>
399
400 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
401 ago.
402
c03ae966
AD		 4032001-12-29 Akim Demaille <akim@epita.fr>
404
405 * src/reader.c, src/reader.h (user_toknums): Remove.
406 Adjust all users to use symbols[i]->user_token_number.
407
5a670b1e
AD		 4082001-12-29 Akim Demaille <akim@epita.fr>
409
410 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
411 Adjust all users to use symbols[i]->prec or ->assoc.
412
ad949da9
AD		 4132001-12-29 Akim Demaille <akim@epita.fr>
414
415 * src/reader.c, src/reader.h (tags): Remove.
416 Adjust all users to use symbols[i]->tag.
417
0e78e603
AD		 4182001-12-29 Akim Demaille <akim@epita.fr>
419
420 * src/gram.h, src/gram.c (symbols): New, similar to state_table
421 and rule_table.
422 * src/reader.c (packsymbols): Fill this table.
423 Drop sprec.
424 * src/conflicts.c (resolve_sr_conflict): Adjust.
425 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
426 single table.
427 Use symbols[i]->tag instead of tags[i].
428
213e640e
AD		 4292001-12-29 Akim Demaille <akim@epita.fr>
430
431 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
432 In addition, put a comment in there, to replace...
433 * tests/regression.at (%union and C comments): Remove.
434
e7b8bef1
AD		 4352001-12-29 Akim Demaille <akim@epita.fr>
436
437 * tests/regression.at (Web2c Actions): Blindly move the actual
438 output as expected output. The contents *seem* right to me, but I
439 can't pretend reading perfectly parser tables... Nonetheless, all
440 the other tests pass correctly, the table look OK, even though the
441 presence of `$axiom' is to be noted: AFAICS it is useless (but
442 harmless).
443
b68e7744
AD		 4442001-12-29 Akim Demaille <akim@epita.fr>
445
446 * src/reader.c (readgram): Don't add the rule 0 if there were no
447 rules read. In other words, add it _after_ having performed
448 grammar sanity checks.
449 Fixes the `tests/regression.at (Invalid input: 1)' Failure.

465 Fix the `GAWK Grammar' failure.
466
467 * src/LR0.c (final_state): Initialize to -1 so that we do compute
468 the reductions of the first state which was mistakenly confused
469 with the final state because precisely final_state was initialized
470 to 0.
471 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
472 now noticed by Bison.
473 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
474 have a reduction on $default.

AD		 5182001-12-27 Paul Eggert <eggert@twinsun.com>
519
520 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
521 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
522 Sparc, as they were causing more porting problems than the
523 (minor) performance improvement was worth.
524
525 Also, catch up with 1.31's YYSTD.

AD		 5272001-12-27 Akim Demaille <akim@epita.fr>

530 0-sentinel. See below.
531 Use -1 as separator, not 0.
532 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
533 Rely on -1 as separator in yyrhs, instead of 0.
534 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
535 twice `Now at end of input', therefore there are two lines less to
536 expect.

545
546 * src/LR0.c (new_state): Recognize the final state by the fact it
547 is reached by eoftoken.
548 (insert_start_shifting_state, insert_eof_shifting_state)
549 (insert_accepting_state, augment_automaton): Remove, since now
550 these states are automatically computed from the initial state.
551 (generate_states): Adjust.
552 * src/print.c: When reporting a rule number to the user, substract
553 1, so that the axiom rule is rule 0, and the first user rule is 1.
554 * src/reduce.c: Likewise.
555 * src/print_graph.c (print_core): For the time being, just as for
556 the report, depend upon --trace-flags to dump the full set of
557 items.
558 * src/reader.c (readgram): Once the grammar read, insert the rule
559 0: `$axiom: START-SYMBOL $'.
560 * tests/set.at: Adjust: rule 0 is now displayed, and since the
561 number of the states has changed (the final state is no longer
562 necessarily the last), catch up.

565
566 Try to make the use of the eoftoken valid. Given that its value
567 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
568 is used instead of > 0 where appropriate, (ii), depend upon nritems
569 instead of the 0-sentinel.
570
571 * src/gram.h, src/gram.c (nritems): New.
572 Expected to be duplication of nitems, but for the time being...
573 * src/reader.c (packgram): Assert nritems and nitems are equal.
574 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
575 * src/closure.c (print_closure, print_fderives): Likewise.

581
582 * src/main.c (main): If there are complains after grammar
583 reductions, then output the report anyway if requested, then die.
584 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
585 * src/reader.c (eoftoken): New.
586 (parse_token_decl): If the token being defined has value `0', it
587 is the eoftoken.
588 (packsymbols): No longer hack `tags' to insert `$' by hand.
589 Be sure to preserve the value of the eoftoken.
590 (reader): Make sure eoftoken is defined.
591 Initialize nsyms to 0: now eoftoken is created just like the others.
592 * src/print.c (print_grammar): Don't special case the eof token.
593 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
594 lie anyway, albeit pleasant.
595 * tests/calc.at: Exercise error messages with eoftoken.
596 Change the grammar so that empty input is invalid.
597 Adjust expectations.
598 When yyungeting, be sure to use a valid yylloc: use last_yylloc.

683 * src/reader.c (symbol_list): `guard' and `guard_line' are new
684 members.
685 (symbol_list_new): Adjust.
686 (copy_action): action_line is the first line, not the last.
687 (copy_guard): Just as for actions, store the `action' only, not
688 the switch/case/break flesh.
689 Don't parse the user action that might follow the guard, let...
690 (readgram): do it, i.e., now, there can be an action after a
691 guard.
692 In other words the guard is just explicitly optional.
693 (packgram): Adjust.
694 * src/output.c (guards_output): New.
695 (output_parser): Call it when needed.
696 (output): Also free the guard and attrs obstacks.
697 * src/files.c, src/files.h (obstack_save): Remove.
698 (output_files): Remove.
699 As a result, if one needs the former `.act' file, using an
700 appropriate skeleton which requires actions and guards is now
701 required.
702 * src/main.c (main): Adjust.
703 * tests/semantic.at: New.
704 * tests/regression.at: Use `input.y' as input file name.

733 (conflicts_print, print_reductions): Use a state_t instead of an
734 integer when referring to a state.
735 As much as possible, depend upon nlookaheads, instead of the
736 `lookaheadsp' member of the following state (since lookaheads of
737 successive states are successive, the difference between state n + 1
738 and n served as the number of lookaheads for state n).

896 otherwise, since we range over their symbols, we might look at a
897 nonterminal which no longer ``exists'', i.e., it is not counted in

1001 Work around Autotest bugs.
1002
1003 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1004 frame, because Autotest understand lines starting with a `+' as
1005 traces from the shell. Then, they are not processed properly.
1006 Admittedly an Autotest bug, but we don't have time to wait for
1007 Autotest to catch up.

1020 * src/print.c (print_actions): Output the handling of `$' as the
1021 traces do: shifting the token EOF. Before EOF was treated as a
1022 nonterminal.
1023 * tests/regression.at: Adjust some tests.
1024 * src/print_graph.c (print_core): Complete the set of items via
1025 closure. The next-to-final and final states are still unsatisfying,
1026 but that's to be addressed elsewhere.
1027 No longer output the rule numbers, but do output the state number.
1028 A single loop for the shifts + gotos is enough, but picked a
1029 distinct color for each.

1146 When looking if the start_symbol is shifted from the initial
