49
50 * src/scan-gram.l: Use more accurate diagnostics, e.g.

56 Also, remove one static variable in the scanner.
57
58 * src/scan-gram.l (braces_level): Now auto, not static.
59 Initialize to zero if the compiler is being picky.
60 (INITIAL): Clear braces_level instead of incrementing it.

79 and yyerror.
80 Have yyerror `use' its arguments.
81 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF

88 clashes.
89 * src/scan-gram.l: Use [\'] instead of ['] to pacify
90 font-lock-mode.

103
104 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
105 New.

123 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
124 (%pure-parser + %parse-param) LALR and GLR parsers.
125 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
126 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
127 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.

136
137 2002-11-03 Akim Demaille <akim@epita.fr>
138
139 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
140 AT_CHECK_CALC_GLR invocations to use % directives, instead of
141 command line options.
142 * tests/cxx-type.at: Formatting changes.
143
144 2002-11-03 Paul Eggert <eggert@twinsun.com>
145
146 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
147 to count columns correctly, and to check for invalid inputs.
148
149 Use mbsnwidth to count columns correctly. Account for tabs, too.
150 Include mbswidth.h.
151 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
152 (extend_location): New function.
153 (YY_LINES): Remove.
154
155 Handle CRLF in C code rather than in Lex code.

161
162 Handle backslash-newline correctly in C code.
163 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.

166 (tag, splice): New EREs. Do not allow NUL or newline in tags.
167 Use {splice} wherever C allows backslash-newline.
168 YY_STEP after space, newline, vertical-tab.
169 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
170
171 (letter, id): Don't assume ASCII; e.g., spell out a-z.
172
173 ({int}, handle_action_dollar, handle_action_at): Check for integer
174 overflow.
175
176 (YY_STEP): Omit trailing semicolon, so that it's more like C.
177
178 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
179 as well as \000. Check for UCHAR_MAX, not 255.
180 Allow \x with an arbitrary positive number of digits, as in C.
181 Check for overflow here.
182 Allow \? and UCNs, for compatibility with C.
183
184 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
185 with quote slot used by complain_at.
186
187 * tests/input.at: Add tests for backslash-newline, m4 quotes
188 in symbols, long literals, and funny escapes in strings.
189
190 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
191 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
192 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
193 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
194 * m4/mbswidth.m4: New file, from GNU coreutils.
195
196 * doc/bison.texinfo (Grammar Outline): Document // comments.

198 nor is backslash-newline allowed.
199 (Actions): Document that trigraphs have no special meaning.
200
201 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
202 no longer used.
203
204 2002-11-02 Paul Eggert <eggert@twinsun.com>
205
206 * src/reader.c: Don't include quote.h; not needed.
207 (get_merge_function): Reword warning to be consistent with
208 type clash diagnostic in grammar_current_rule_check.
209
210 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
211 bug in trigraph handling.
212
213 * src/output.c (prepare_symbols): When printing token names,
214 escape "[" as "@<:@" and likewise for "]".
215
216 * src/system.h (errno): Remove declaration, as we are now
217 assuming C89 or better, and C89 guarantees errno.
218
219 2002-10-30 Paul Eggert <eggert@twinsun.com>
220
221 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
222 Check for close failures.
223 * src/files.h (xfclose): Return void, not int, since it always
224 returned zero.
225 * src/files.c (xfclose): Likewise. Report I/O error if ferror
226 indicates one.
227 * src/output.c (output_skeleton): Use xfclose rather than fclose
228 and ferror. xfclose now checks ferror.
229
230 * data/glr.c (YYLEFTMOST_STATE): Remove.
231 (yyreportTree): Use a stack-based leftmost state. This avoids
232 our continuing battles with bogus warnings about initializers.
233
234 2002-10-30 Akim Demaille <akim@epita.fr>
235
236 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
237 #if.
238
239 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
240
241 * tests/glr-regr1.at: New test for reported regressions.
242 * tests/testsuite.at: Add glr-regr1.at test.
243 * tests/Makefile.am: Add glr-regr1.at test.
244
245 2002-10-24 Paul Eggert <eggert@twinsun.com>
246
247 Version 1.75a.
248
249 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
250 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
251 we use malloc. Don't assume 'A' through 'Z' are contiguous.
252 Don't assume strdup exists; POSIX says its an XSI extension.
253 Check for buffer overflow on input.
254
255 2002-10-24 Akim Demaille <akim@epita.fr>
256
257 * src/output.c (output_skeleton): Don't disable M4sugar comments
258 too soon: it results in comments being expanded.
259 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
260 first output.
261
262 2002-10-24 Akim Demaille <akim@epita.fr>
263
264 * data/yacc.c (m4_int_type): New.
265 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
266 char' as only yacc.c wants K&R portability.
267 * data/glr.c (yysigned_char): Remove.
268 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
269 Reported by Quoc Peyrot.
270
271 2002-10-23 Paul Eggert <eggert@twinsun.com>
272
273 * src/main.c (main): With --trace=time, report times even if a
274 non-fatal error occurs. Formerly, the times were reported in some
275 such cases but not in others.
276 * src/reader.c (reader): Just return if a complaint has been issued,
277 instead of exiting, so that 'main' can report times.
278
279 2002-10-22 Akim Demaille <akim@epita.fr>
280
281 * src/system.h: Include sys/types.
282 Reported by Bert Deknuydt.
283
284 2002-10-23 Paul Eggert <eggert@twinsun.com>
285
286 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
287 Suggested by Art Haas.
288
289 2002-10-22 Paul Eggert <eggert@twinsun.com>
290
291 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
292 decl; not needed any more.
293 * src/main.c (main): Use return to exit, undoing yesterday's change.
294 The last OS that we could find where this wouldn't work is
295 SunOS 3.5, and that's too old to worry about now.
296
297 * data/glr.c (struct yyltype): Define members even when not
298 doing locations. This is more consistent with yacc.c, and it
299 works around the following bug reports:
300 http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html
301 http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
302 and I hope it also fixes this bug report:
303 http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html
304
305 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
306 @acronym consistently. Standardize on "Yacc" instead of "YACC",
307 "Algol" instead of "ALGOL". Give a bit more history about BNF.
308
309 2002-10-22 Akim Demaille <akim@epita.fr>
310
311 * data/README: New.
312
313 2002-10-21 Paul Eggert <eggert@twinsun.com>
314
315 Be consistent about 'bool'; the old code used an enum in one
316 module and an int in another, and this violates the C standard.
317 * m4/stdbool.m4: New file, from coreutils 4.5.3.
318 * configure.ac (AC_HEADER_STDBOOL): Add.
319 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
320 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
321 * src/symtab.c (hash_compare_symbol_t): Likewise.
322 * src/system.h (bool, false, true): Use a definition consistent
323 with ../lib/hash.c. All uses changed.
324
325 * src/complain.c (warning_issued): Renamed from warn_message_count,
326 so that we needn't worry about integer overflow (!).
327 Now of type bool. All uses changed.
328 (complaint_issued): Renamed from complain_message_count; likewise.
329
330 * src/main.c (main): Use exit to exit with failure.
331
332 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
333 rather than 1 and 0.
334 * src/main.c (main): Likewise.
335 * src/getargs.c (getargs): Likewise.
336 * src/reader.c (reader): Likewise.
337
338 * src/getarg.c (getargs): Remove duplicate code for
339 "Try `bison --help'".
340
341 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
342 What was that "2" for?
343
344 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
345 * src/getargs.c (usage): Likewise.
346
347 * src/getargs.c (getargs): When there are too few operands, report
348 the last one. When there are too many, report the first extra
349 one. This is how diffutils does it.
350
351 2002-10-20 Paul Eggert <eggert@twinsun.com>
352
353 Remove K&R vestiges.
354 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
355 * src/complain.c (VA_START): Remove. Assume prototypes.
356 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
357 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
358 fatal): Assume prototypes.
359 * src/complain.h: Assume prototypes.
360 * src/system.h (PARAMS): Remove.
361 Include <limits.h> unconditionally, since it's guaranteeed even
362 for a freestanding C89 compiler.
363 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
364 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
365
366 2002-10-20 Akim Demaille <akim@epita.fr>
367
368 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
369 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
370 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
371 (yyresolveStates, yyresolveAction, yyresolveStack)
372 (yyprocessOneStack): Use them.
373 (yy_reduce_print): New.
374 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
375
376 2002-10-20 Akim Demaille <akim@epita.fr>
377
378 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
379 arguments and output `void'.
380 (b4_c_function): Rename as...
381 (b4_c_function_def): this.
382 (b4_c_function_decl, b4_c_ansi_function_def)
383 (b4_c_ansi_function_decl): New.
384 Change the interpretation of the arguments: before `int, foo', now
385 `int foo, foo'.
386 * data/yacc.c (yyparse): Prototype and define thanks to these.
387 Adjust b4_c_function_def uses.
388 * data/glr.c (yyparse): Likewise, but ANSI only.
389
390 2002-10-20 Akim Demaille <akim@epita.fr>
391
392 * src/output.c (prepare): Move the definition of `tokens_number',
393 `nterms_number', `undef_token_number', `user_token_number_max'
394 to...
395 (prepare_tokens): Here.
396 (prepare_tokens): Rename as...
397 (prepare_symbols): this.
398 (prepare): Move the definition of `rules_number' to...
399 (prepare_rules): here.
400 (prepare): Move the definition of `last', `final_state_number',
401 `states_number' to...

404
405 2002-10-20 Akim Demaille <akim@epita.fr>
406
407 * src/tables.h, src/tables.c, src/output.c: Comment changes.
408
409 2002-10-20 Akim Demaille <akim@epita.fr>
410
411 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
412 * data/c.m4: here.
413
414 2002-10-20 Akim Demaille <akim@epita.fr>
415
416 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
417 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
418 `pair'.
419 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
420 `name' to...
421 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
422 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
423 These.
424
425 2002-10-19 Paul Eggert <eggert@twinsun.com>
426
427 Do not create a temporary file, as that involves security and
428 cleanup headaches. Instead, use a pair of pipes.
429 Derived from a suggestion by Florian Krohm.
430 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
431 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
432 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.

437 * po/POTFILES.in: Add lib/subpipe.c.
438 * src/output.c: Include "subpipe.h".
439 (m4_invoke): Remove decl.
440 (scan_skel): New decl.
441 (output_skeleton): Use pipe rather than temporary file for m4 input.
442 Check that m4sugar.m4 is readable, to avoid deadlock.
443 Check for pipe I/O error.
444 * src/scan-skel.l (readpipe): Remove decl.
445 (scan_skel): New function, to be used in place of m4_invoke.
446 Read from stream rather than file.
447
448 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
449 float, as this generates a warning on Solaris 8 + GCC 3.2 with
450 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
451 this generates a more-accurate value anyway.
452
453 * lib/timevar.c (timervar_accumulate): Rename locals to
454 avoid confusion with similarly-named more-global.
455 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
456
457 * src/output.c (prepare): Use xstrdup to convert char const *
458 to char *, to avoid GCC warning.
459
460 2002-10-19 Akim Demaille <akim@epita.fr>
461
462 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
463 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
464 Use them to have `calc.y' ready for %pure-parser.
465 * data/yacc.c (YYLEX): Pass a yylex return type to
466 b4_c_function_call.
467
468 2002-10-19 Akim Demaille <akim@epita.fr>
469
470 Prototype support of %lex-param and %parse-param.
471
472 * src/parse-gram.y: Add the definition of the %lex-param and
473 %parse-param tokens, plus their rules.
474 Drop the `_' version of %glr-parser.
475 Add the "," token.
476 * src/scan-gram.l (INITIAL): Scan them.
477 * src/muscle_tab.c: Comment changes.
478 (muscle_insert, muscle_find): Rename `pair' as `probe'.
479 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
480 (muscle_entry_s): The `value' member is no longer const.
481 Adjust all dependencies.
482 * src/muscle_tab.c (muscle_init): Adjust: use
483 MUSCLE_INSERT_STRING.
484 Initialize the obstack earlier.
485 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
486 (muscle_pair_list_grow): New.
487 * data/c.m4 (b4_c_function_call, b4_c_args): New.
488 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
489 * tests/calc.at: Use %locations, not --locations.
490 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
491
492 2002-10-19 Akim Demaille <akim@epita.fr>
493
494 * src/getargs.c (usage): Take status as argument and exit
495 accordingly.
496 Report the traditional `Try ... --help' message when status != 0.
497 (usage, version): Don't take a FILE * as arg, it is pointless.
498 (getargs): When there is an incorrect number of arguments, make it
499 an error, and report it GNUlically thanks to `usage ()'.
500
501 2002-10-18 Paul Eggert <eggert@twinsun.com>
502
503 * data/glr.c (yyreportParseError): Don't assume that sprintf
504 yields the length of the printed string, as this is not true
505 on SunOS 4.1.4. Reported by Peter Klein.
506
507 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
508 * tests/conflicts.at (%nonassoc and eof): Likewise.
509 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
510
511 2002-10-17 Akim Demaille <akim@epita.fr>
512
513 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
514 * src/getargs.c (trace_types, trace_args): Adjust.
515 * src/reader.c (grammar_current_rule_prec_set)
516 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
517 Standardize error messages.
518 And s/@prec/%prec/!
519 (reader): Use trace_flag to enable scanner/parser debugging,
520 instead of an adhoc scheme.
521 * src/scan-gram.l: Remove trailing debugging code.
522
523 2002-10-16 Paul Eggert <eggert@twinsun.com>
524
525 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
526 MUSCLE_TAB_H.
527
528 * NEWS: Officially drop support for building Bison with K&R C,
529 since it didn't work anyway and it's not worth worrying about.
530 * Makefile.maint (wget_files): Remove ansi2knr.c.
531 (ansi2knr.c-url_prefix): Remove.
532 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
533 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
534 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
535
536 2002-10-15 Paul Eggert <eggert@twinsun.com>
537
538 Stop using the "enum_" trick for K&R-style function definitions;
539 it confused me, and I was the author! Instead, assume that people
540 who want to use K&R C compilers (when using these modules in GCC,
541 perhaps?) will run ansi2knr.
542
543 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
544 All uses of "enum_" changed to "enum ".
545 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
546 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
547
548 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

556 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
557 Use function prototypes; this removes the need for declaring
558 static functions simply to provide their prototypes.
559 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

611
612 2002-10-14 Akim Demaille <akim@epita.fr>
613
614 Version 1.75.
615
616 2002-10-14 Akim Demaille <akim@epita.fr>
617
618 * tests/Makefile.am (maintainer-check-posix): New.
619
620 2002-10-14 Akim Demaille <akim@epita.fr>
621
622 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
623 member.
624
625 2002-10-14 Akim Demaille <akim@epita.fr>
626
627 * src/tables.c (table_ninf_remap): base -> tab.
628 Reported by Matt Rosing.
629
630 2002-10-14 Paul Eggert <eggert@twinsun.com>
631
632 * tests/action.at, tests/calc.at, tests/conflicts.at,
633 tests/cxx-type.at, tests/headers.at, tests/input.at,
634 tests/regression.at, tests/synclines.at, tests/torture.at:
635 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
636 so that the tests still work even if POSIXLY_CORRECT is set.
637 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
638
639 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
640 for portability to K&R hosts. Fix typo: signed char is guaranteed
641 only to 127, not to 128.
642 * data/glr.c (yysigned_char): New type.
643 * data/yacc.c (yysigned_char): Likewise.
644 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
645
646 2002-10-13 Paul Eggert <eggert@twinsun.com>
647
648 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
649 true due to limited range of data type" warning from GCC.
650
651 * data/c.m4 (b4_token_defines): Protect against double-inclusion
652 by wrapping enum yytokentype's definition inside #ifndef
653 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
654
655 2002-10-13 Akim Demaille <akim@epita.fr>
656
657 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
658 Un yy- yyrhs to avoid the name clash with the global YYRHS.
659
660 2002-10-13 Akim Demaille <akim@epita.fr>
661
662 * Makefile.maint: Update from Autoconf 2.54.
663 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
664
665 2002-10-13 Akim Demaille <akim@epita.fr>
666
667 * src/print.c (print_state): Separate the list of solved conflicts
668 from the other items.
669 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
670
671 2002-10-13 Akim Demaille <akim@epita.fr>
672
673 Let nondeterministic skeletons be usable with deterministic
674 tables.
675
676 With the patch, GAWK compiled by GCC without -O2 passes its test
677 suite using a GLR parser driven by LALR tables. It fails with -O2
678 because `struct stat' gives two different answers on my machine:
679 88 (definition of an auto var) and later 96 (memset on this var).
680 Hence the stack is badly corrumpted. The headers inclusion is to
681 blame: if I move the awk.h inclusion before GLR's system header
682 inclusion, the two struct stat have the same size.
683
684 * src/tables.c (pack_table): Always create conflict_table.
685 (token_actions): Always create conflict_list.
686 * data/glr.c (YYFLAG): Remove, unused.
687
688 2002-10-13 Akim Demaille <akim@epita.fr>
689
690 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
691 (O0FLAGS): New.
692 (VALGRIND, GXX): New.
693 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
694 * tests/bison.in: Run $PREBISON a pre-command.
695 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
696 (maintainer-check-g++): New.
697 * Makefile.am (maintainer-check): New.
698
699 2002-10-13 Akim Demaille <akim@epita.fr>
700
701 * data/glr.c: Formatting changes.
702 Tweak some trace messages to match yacc.c's.
703
704 2002-10-13 Akim Demaille <akim@epita.fr>
705
706 GLR parsers sometimes raise parse errors instead of performing the
707 default reduction.
708 Reported by Charles-Henry de Boysson.
709
710 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
711 check the length of the traces when %glr.
712 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
713 GLR's traces.
714 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
715 Test GLR parsers.
716 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
717 (yyltype): Remove the yy prefix from the member names.
718 (yytable): Complete its comment.
719 (yygetLRActions): Map error action number from YYTABLE from
720 YYTABLE_NINF to 0.
721 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
722 (which was a bug: it should have been YYTABEL_NINF, and yet it was
723 not satisfying as we could compare an YYACTION computed from
724 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
725 only value for error actions.
726 (yyreportParseError): In verbose parse error messages, don't issue
727 `error' in the list of expected tokens.
728 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
729 next action to perform to match glr.c's decoding.
730 (yytable): Complete its comment.
731
732 2002-10-13 Paul Eggert <eggert@twinsun.com>
733
734 Fix problem reported by Henrik Grubbstroem in
735 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
736 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
737 because the Bison parser reads the second action before reducing
738 the first one.
739 * src/scan-gram.l (rule_length): New static var.
740 Use it to keep track of the rule length in the scanner, since
741 we can't expect the parser to be in lock-step sync with the scanner.
742 (handle_action_dollar, handle_action_at): Use this var.
743 * tests/actions.at (Exotic Dollars): Test for the problem.
744
745 2002-10-12 Paul Eggert <eggert@twinsun.com>
746
747 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
748 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
749 Include <sys/time.h> when checking for clock_t and struct tms.
750 Use same include order as source.
751 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
752 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.
753
754 * lib/timevar.c: Update copyright date and clarify comments.
755 (get_time) [IN_GCC]: Keep the GCC version for reference.
756
757 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
758 GCC version as of today, then merge Bison's changes.
759 Change "GCC" to "Bison" in copyright notice. timevar.def's
760 author is Akim, so change that too.
761
762 * src/reader.c (grammar_current_rule_check):
763 Don't worry about the default action if $$ is untyped.
764 Prevents bogus warnings reported by Jim Gifford in
765 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>.
766
767 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
768 * data/glr.c, data/lalr1.cc, data/yacc.c:
769 Output token definitions before the first part of user declarations.
770 Fixes compatibility problem reported by Jim Gifford for kbd in
771 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.
772
773 2002-10-11 Paul Eggert <eggert@twinsun.com>
774
775 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
776 (yyparse): here. This undoes some of the 2002-07-25 change.
777 Compatibility problem reported by Ralf S. Engelschall with
778 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
779
780 2002-10-11 Akim Demaille <akim@epita.fr>
781
782 * tests/regression.at Characters Escapes): New.

784 characters.
785 Reported by Jan Nieuwenhuizen.
786
787 2002-10-11 Akim Demaille <akim@epita.fr>
788

790
791 2002-10-10 Paul Eggert <eggert@twinsun.com>
792
793 Portability fixes for bitsets; this also avoids several GCC
794 warnings.
795
796 * lib/abitset.c: Include <stddef.h>, for offsetof.
797 * lib/lbitset.c: Likewise.
798
799 * lib/abitset.c (abitset_bytes): Return a size that is aligned
800 properly for vectors of objects. Do not assume that adding a
801 header size to a multiple of a word size yields a value that is
802 properly aligned for the whole union.
803 * lib/bitsetv.c (bitsetv_alloc): Likewise.
804
805 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
806 unique names for structures.
807 * lib/ebitset.c (ebitset_bytes): Likewise.
808 * lib/lbitset.c (lbitset_bytes): Likewise.
809

835 * lib/ebitset.h: Likewise.
836 * lib/lbitset.h: Likewise.
837
838 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
839 All instances of parameters of type enum bitset_opts are now of
840 type enum_bitset_opts, to conform to the C Standard, and similarly
841 for enum_bitset_type.
842 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
843 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
844
845 Do not use "struct bitset_struct" to mean different things in
846 different modules. Not only is this confusing, it violates
847 the C Standard, which requires that structure types in different
848 modules must be compatible if one is to be passed to the other.
849 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
850 All instances of "struct bitset_struct *" replaced with "bitset".
851 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
852 (union bitset_union, struct abitset_struct, struct ebitset_struct,
853 struct lbitset_struct, struct bitset_stats_struct): New types.
854 All uses of struct bitset_struct changed to union bitset_union,
855 etc.
856 * lib/abitset.c (struct abitset_struct, abitset,
857 struct bitset_struct): Remove.
858 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,

861 bitset_struct): Remove.
862 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
863 Likewise.
864
865 Do not call a function of type T using a call that assumes the
866 function is of a different type U. Standard C requires that a
867 function must be called with a type that is compatible with its
868 definition.
869 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
870 New decls.
871 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
872 New functions.
873 * lib/ebitset.c (PFV): Remove.
874 * lib/lbitset.c (PFV): Likewise.

882 (lbitset_vtable): Use them.
883
884 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
885 Declare.
886
887 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
888 GCC warning.
889 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
890 Use offsetof, for simplicity.
891
892 2002-10-06 Paul Eggert <eggert@twinsun.com>
893
894 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
895 the same width as int. This reapplies a hunk of the 2002-08-12 patch
896 <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
897 which was inadvertently undone by the 2002-09-30 patch.
898 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
899 the same width as int.
900

911 the portable Standard C character set.
912
913 The GNU coding standard says CFLAGS and YFLAGS are reserved
914 for the installer to set.
915 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
916 * src/Makefile.am (AM_CFLAGS): Likewise.
917 (AM_YFLAGS): Renamed from YFLAGS.

924
925 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
926 POSIX 1003.1-2001 has removed fgrep.
927

1000 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
1001 to BITSET_WINDEX_MAX.
1002
1003 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
1004 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

1104
1105 * doc/bison.texinfo (Conditions): Make explicit that the GPL

1156 functions are not portable. Do not assume size_t is the
1157 same width as int.
1158 (yypstates): Do not assume that ptrdiff_t is the same width
1159 as int, and similarly for yyposn and YYINDEX.
1160
1161 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

1199
1200 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
1201 PROTOTYPES to check for prototypes, and "defined __STDC__" to
1202 check for void *.
1203
1204 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
1205 size_t; the old version tried to do this but casted improperly.
1206 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
1207 (bitset_test): Now returns int, not unsigned long.
1208

1210 (_): New macro.
1211 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
1212 name locals "index", as it generates unnecessary warnings on some
1213 hosts that have an "index" function.

1216 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

1237 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,

1245
1246 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
1247
1248 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
1249
1250 * src/main.c (main): Cast result of bindtextdomain and textdomain
1251 to void, to avoid a GCC warning when --disable-nls is in effect.
1252
1253 * src/scan-gram.l: Use strings rather than escapes when possible,
1254 to minimize the number of warnings from xgettext.
1255 (handle_action_dollar, handle_action_at): Don't use isdigit,
1256 as it mishandles negative chars and it may not work as expected
1257 outside the C locale.
1258
1259 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
1260 this is a GCC extension and is not portable to other compilers.

1340

1442 different: save its reduction (accept) instead of having a state
1443 without any action (no shift or goto, no reduce).
1444 Note: the final state is now a ``regular'' state, i.e., the
1445 parsers now contain `reduce 0' as default reduction.

1490 2002-07-26 Akim Demaille <akim@epita.fr>
1491
1492 * src/reader.h, src/reader.c (gram_error): ... can't get
1493 yycontrol without making too strong assumptions on the parser
1494 itself.
1495 * src/output.c (prepare_tokens): Use the real 0th value of
1496 token_translations instead of `0'.
1497 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
1498 visible here.
1499 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
1500 for the time being: %locations ought to provide it to yyerror.
1501
1502 2002-07-25 Akim Demaille <akim@epita.fr>
1503
1504 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

3037
3038 * src/reader.c (copy_at, copy_dollarm parse_braces, parse_action)
3039 (parse_guard): Rename the formal argument `stack_offset' as
3040 `rule_length', which is more readable.
3041 Adjust callers.
3042 (copy_at, copy_dollar): Instead of outputting the hard coded
3043 values of $$, $n and so forth, output invocation to b4_lhs_value,
3044 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
3045 Note: this patch partially drops `semantic-parser' support: it
3046 always does `rule_length - n', where semantic parsers ought to
3047 always use `-n'.
3048 * data/bison.simple, data/bison.c++ (b4_lhs_value)
3049 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

3095 2002-04-24 Robert Anisko <robert@lrde.epita.fr>
3096
3097 * tests/calc.at: Exercise prologue splitting.
3098
3099 * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and

3101
3102 * src/output.c (prepare): Add the `pre_prologue' and `post_prologue'
3103 muscles.
3104 (output): Free pre_prologue_obstack and post_prologue_obstack.

3119 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
3120 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
3121 constructors or destructors.

3151
3152 2002-04-22 Akim Demaille <akim@epita.fr>
3153
3154 * src/reader.c (token_translations_init): 256 is now the default
3155 value for the error token, i.e., it will be assigned another
3156 number if the user assigned 256 to one of her tokens.
3157 (reader): Don't force 256 to error.
3158 * doc/bison.texinfo (Symbols): Adjust.
3159 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
3160 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
3161 etc. instead of 10, 20, 30 (which was used to `jump' over error
3162 (256) and undefined (2)).
3163
3164 2002-04-22 Akim Demaille <akim@epita.fr>
3165
3166 Propagate more token_number_t.

3185 as Lex/Flex'.
3186 (Debugging): More details about enabling the debugging features.
3187 (Table of Symbols): Describe $$, $n, @$, and @n.
3188 Suggested by Tim Josling.

3197 Suggested by Paul Eggert.
3198
3199 2002-04-09 Akim Demaille <akim@epita.fr>
3200
3201 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
3202 full stderr, and strip it according to the bison options, instead
3203 of composing the error message from different bits.
3204 This makes it easier to check for several error messages.
3205 Adjust all the invocations.
3206 Add an invocation exercising the error token.
3207 Add an invocation demonstrating a stupid error message.
3208 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
3209 Adjust the tests.
3210 Error message are for stderr, not stdout.

3212 2002-04-09 Akim Demaille <akim@epita.fr>
3213
3214 * src/gram.h, src/gram.c (error_token_number): Remove, use
3215 errtoken->number.

3218 * src/gram.h (token_number_t): Move to...
3219 * src/symtab.h: here.
3220 (state_t.number): Is a token_number_t.
3221 * src/print.c, src/reader.c: Use undeftoken->number instead of
3222 hard coded 2.
3223 (Even though this 2 is not the same as above: the number of the
3224 undeftoken remains being 2, it is its user token number which
3225 might not be 2).
3226 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
3227 `user_token_number_max'.
3228 Output `undef_token_number'.
3229 * data/bison.simple, data/bison.c++: Use them.
3230 Be sure to map invalid yylex return values to
3231 `undef_token_number'. This saves us from gratuitous SEGV.
3232
3233 * tests/conflicts.at (Solved SR Conflicts)
3234 (Unresolved SR Conflicts): Adjust.
3235 * tests/regression.at (Web2c Actions): Adjust.

3243 Use __ofile__.
3244 * data/bison.simple: Use __ofile__.

3248
3249 * src/gram.h (item_number_t): New, the type of item numbers in
3250 RITEM. Note that it must be able to code symbol numbers as
3251 positive number, and the negation of rule numbers as negative
3252 numbers.
3253 Adjust all dependencies (pretty many).
3254 * src/reduce.c (rule): Remove this `short *' pointer: use
3255 item_number_t.
3256 * src/system.h (MINSHORT, MAXSHORT): Remove.
3257 Include `limits.h'.
3258 Adjust dependencies to using SHRT_MAX and SHRT_MIN.

3265 500.
3266 * tests/regression.at (Web2c Actions): Ajust.
3267
3268 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
3269 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
3270 passes, but produces negative #line number, once fixed, GCC is
3271 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
3272 C), it passes.
3273 * src/state.h (state_h): Code input lines on ints, not shorts.
3274
3275 2002-04-08 Akim Demaille <akim@epita.fr>
3276

3772
3773 Remove the support for C++ namespace cleanliness; it was
3774 causing more problems than it was curing, since it didn't work
3775 properly on some nonstandard C++ compilers. This can wait

3821 more consistent when naming methods and variables. Put preprocessor
3822 directives around tables only needed for debugging.
3823
3824 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
3825
3826 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
3827 C++ parsers.
3828 (yy::b4_name::parse): Use print_.

3849 2002-02-05 Akim Demaille <akim@epita.fr>
3850
3851 * data/bison.c++: Adjust to the M4 back end.
3852 More is certainly needed.
3853
3854 2002-02-05 Akim Demaille <akim@epita.fr>
3855
3856 Give a try to M4 as a back end.
3857

3869 action member.
3870 Adjust callers.
3871 (output_skeleton): Don't look for the skeleton location, let m4 do
3872 that.
3873 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
3874 file will be used.
3875 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
3876 (prepare): Given that for the time being changesyntax is not
3877 usable in M4, rename the muscles using `-' to `_'.

3879 * src/output.h (actions_output, guards_output)
3880 (token_definitions_output): Adjust prototypes.
3881 * src/scan-skel.l: Instead of scanning the skeletons, it now
3882 processes the output of m4: `__oline__' and `#output'.
3883 * data/bison.simple: Adjust to be used by M4(sugar).
3884 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
3885 to date.
3886 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
3887 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
3888 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
3889 shamelessly stolen from CVS Autoconf.

3899 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
3900 which have no values.
3901
3902 2002-02-05 Akim Demaille <akim@epita.fr>
3903
3904 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
3905 * data/: here.
3906
3907 2002-01-29 Paul Eggert <eggert@twinsun.com>
3908
3909 * src/bison.simple (YYSIZE_T): Do not define merely because
3910 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
3911 On some platforms, <alloca.h> does not declare YYSTD (size_t).
3912
3913 2002-01-27 Akim Demaille <akim@epita.fr>
3914
3915 Fix `%nonassoc and eof'.
3916
3917 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
3918 which were not properly copied! Replace
3919 memcpy (res->errs, src->errs, src->nerrs);
3920 with
3921 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
3922 !!!
3923 * tests/regression.at (%nonassoc and eof): Adjust to newest
3924 Autotest: `.' is not in the PATH.
3925
3926 2002-01-27 Akim Demaille <akim@epita.fr>
3927
3928 * tests/sets.at (AT_EXTRACT_SETS): New.
3929 (Nullable): Use it.
3930 (Firsts): New.
3931
3932 2002-01-26 Akim Demaille <akim@epita.fr>
3933
3934 * tests/actions.at, tests/calc.at, tests/headers.at,
3935 * tests/torture.at: Adjust to the newest Autotest which no longer
3936 forces `.' in the PATH.
3937
3938 2002-01-25 Akim Demaille <akim@epita.fr>
3939
3940 * tests/regression.at (%nonassoc and eof): New.
3941 Suggested by Robert Anisko.
3942
3943 2002-01-24 Akim Demaille <akim@epita.fr>
3944
3945 Bison dumps core when trying to complain about broken input files.
3946 Reported by Cris van Pelt.
3947
3948 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
3949 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
3950 into...
3951 (Invalid inputs): Strengthen: exercise parse_percent_token.
3952
3953 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
3954
3955 * src/Makefile.am: Add bison.c++.
3956 * src/bison.c++: New skeleton.
3957
3958 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
3959
3960 * po/it.po: New.
3961
3962 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
3963
3964 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
3965
3966 2002-01-20 Marc Autret <marc@gnu.org>
3967
3968 * src/files.c (compute_output_file_names): Fix
3969
3970 2002-01-20 Marc Autret <marc@gnu.org>
3971
3972 * tests/output.at: New test.
3973 * src/files.c (compute_base_names): Don't map extensions when
3974 the YACC flag is set, use defaults.
3975 Reported by Evgeny Stambulchik.
3976
3977 2002-01-20 Marc Autret <marc@gnu.org>
3978
3979 * src/system.h: Need to define __attribute__ away for non-GCC
3980 compilers as well (i.e. the vendor C compiler).
3981 Suggested by Albert Chin-A-Young.
3982
3983 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
3984
3985 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
3986 canonical definition.
3987 * src/system.h: Use the canonical definition for PARAMS (avoids
3988 a conflict with the macro from lib/hash.h).
3989
3990 2002-01-11 Akim Demaille <akim@epita.fr>
3991
3992 * configure.in: Use AC_FUNC_STRNLEN.
3993 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
3994
3995 2002-01-09 Akim Demaille <akim@epita.fr>
3996
3997 * src/files.c, src/files.h (output_infix): New.
3998 (tab_extension): Remove.
3999 (compute_base_names): Compute the former, drop the latter.
4000 * src/output.c (prepare): Insert the muscles `output-infix', and
4001 `output-suffix'.
4002 * src/parse-skel.y (string, string.1): New.
4003 (section.header): Use it.
4004 (section.yacc): Remove.
4005 (prefix): Remove too.
4006 * src/scan-skel.l: Adjust.
4007 * src/bison.simple, src/bison.hairy: Adjust.
4008
4009 2002-01-09 Akim Demaille <akim@epita.fr>
4010
4011 * configure.in (WERROR_CFLAGS): Compute it.
4012 * src/Makefile.am (CFLAGS): Pass it.
4013 * tests/atlocal.in (CFLAGS): Idem.
4014 * src/files.c: Fix a few warnings.
4015 (get_extension_index): Remove, unused.
4016
4017 2002-01-08 Akim Demaille <akim@epita.fr>
4018
4019 * src/getargs.c (AS_FILE_NAME): New.
4020 (getargs): Use it to convert DOSish file names.
4021 * src/files.c (base_name): Rename as full_base_name to avoid
4022 clashes with `base_name ()'.
4023 (filename_split): New.
4024 (compute_base_names): N-th rewrite, using filename_split.
4025
4026 2002-01-08 Akim Demaille <akim@epita.fr>
4027
4028 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
4029 New, stolen from the Fileutils 4.1.
4030 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
4031 * configure.in: Check for the presence of memrchr, and of its
4032 prototype.
4033
4034 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
4035
4036 * lib/hash.h (__P): Added definition for this macro.
4037 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
4038 BUILT_SOURCES, to ensure they are generated first.
4039 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
4040 %error-verbose to allow bootstrapping with bison 1.30x.
4041
4042 2002-01-06 Akim Demaille <akim@epita.fr>
4043
4044 * src/reader.c (parse_braces): Don't fetch the next char, the
4045 convention is to fetch on entry.
4046 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
4047 'switch' without a following semicolon.
4048 * tests/regression.at (braces parsing): New.
4049
4050 2002-01-06 Akim Demaille <akim@epita.fr>
4051
4052 Bison is dead wrong in its RR conflict reports.
4053
4054 * tests/torture.at (GNU Cim Grammar): New.
4055 * src/conflicts.c (count_rr_conflicts): Fix.
4056
4057 2002-01-06 Akim Demaille <akim@epita.fr>
4058
4059 Creating package.m4 from configure.ac causes too many problems.
4060
4061 * tests/Makefile.am (package.m4): Create it by hand,
4062 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
4063
4064 2002-01-06 Akim Demaille <akim@epita.fr>
4065
4066 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
4067 skeleton.h.
4068
4069 2002-01-04 Paul Eggert <eggert@twinsun.com>
4070
4071 * doc/bison.texinfo (Debugging):
4072 Remove YYSTDERR; it's no longer defined or used.
4073 Also, s/cstdio.h/cstdio/.
4074
4075 2002-01-03 Akim Demaille <akim@epita.fr>
4076
4077 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
4078
4079 2002-01-03 Akim Demaille <akim@epita.fr>
4080
4081 * src/parse-skel.y (process_skeleton): Don't bind the parser's
4082 tracing code to --trace, wait for a better --trace option, with
4083 args.
4084
4085 2002-01-03 Akim Demaille <akim@epita.fr>
4086
4087 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
4088 The ISO C++ standard is extremely clear about it: stderr is
4089 considered a macro, not a regular symbol (see table 94 `Header
4090 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
4091 Therefore std:: does not apply to it. It still does with fprintf.
4092 Also, s/cstdio.h/cstdio/.
4093
4094 2002-01-03 Akim Demaille <akim@epita.fr>
4095
4096 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
4097 for non system headers.
4098
4099 2002-01-02 Akim Demaille <akim@epita.fr>
4100
4101 Equip the skeleton chain with location tracking, runtime trace,
4102 pure parser and scanner.
4103
4104 * src/parse-skel.y: Request a pure parser, locations, and prefix
4105 renaming.
4106 (%union): Having several members with the same type does not help
4107 type mismatches, simplify.
4108 (YYPRINT, yyprint): New.
4109 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
4110 (skel_error): this.
4111 Handle locations.
4112 * src/scan-skel.l: Adjust to these changes.
4113 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
4114 (LOCATION_PRINT, skel_control_t): New.
4115
4116 2001-12-30 Akim Demaille <akim@epita.fr>
4117
4118 * src/parse-skel.y: Get rid of the shift/reduce conflict:
4119 replace `gb' with BLANKS.
4120 * src/scan-skel.l: Adjust.
4121
4122 2001-12-30 Akim Demaille <akim@epita.fr>
4123
4124 * src/system.h: We don't need nor want bcopy.
4125 Throw away MS-DOS crap: we don't need getpid.
4126 * configure.in: We don't need strndup. It was even causing
4127 problems: because Flex includes the headers *before* us,
4128 _GNU_SOURCE is not defined by config.h, and therefore strndup was
4129 not visible.
4130 * lib/xstrndup.c: New.
4131 * src/scan-skel.l: Use it.
4132 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
4133 * src/parse-skel.y: Use %directives instead of #defines.
4134
4135 2001-12-30 Akim Demaille <akim@epita.fr>
4136
4137 * src/skeleton.h: New.
4138 * src/output.c (output_parser, output_master_parser): Remove, dead
4139 code.
4140 * src/output.h (get_lines_number, actions_output, guards_output)
4141 (token_definitions_output): Prototype them.
4142 * src/parse-skel.y: Add the license notice.
4143 Include output.h and skeleton.h.
4144 (process_skeleton): Returns void, and takes a single parameter.
4145 * src/scan-skel.l: Add the license notice.
4146 Include skeleton.h.
4147 Don't use %option yylineno: it seems that then Flex imagines
4148 REJECT has been used, and therefore it won't reallocate its
4149 buffers (which makes no other sense to me than a bug). It results
4150 in warnings for `unused: yy_flex_realloc'.
4151
4152 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
4153
4154 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4155 (MUSCLE_INSERT_PREFIX): ...to there.
4156 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4157 (MUSCLE_INSERT_PREFIX): Move from here...
4158
4159 * src/bison.hairy: Add a section directive. Put braces around muscle
4160 names. This parser skeleton is still broken, but Bison should not
4161 choke on a bad muscle 'syntax'.
4162 * src/bison.simple: Add a section directive. Put braces around muscle
4163 names.
4164
4165 * src/files.h (strsuffix, stringappend): Add declarations.
4166 (tab_extension): Add declaration.
4167 (short_base_name): Add declaration.
4168
4169 * src/files.c (strsuffix, stringappend): No longer static. These
4170 functions are used in the skeleton parser.
4171 (tab_extension): New.
4172 (compute_base_names): Use the computations done in this function
4173 to guess if the generated parsers should have '.tab' in their
4174 names.
4175 (short_base_name): No longer static.
4176
4177 * src/output.c (output_skeleton): New.
4178 (output): Disable call to output_master_parser, and give a try to
4179 a new skeleton handling system.
4180 (guards_output, actions_output): No longer static.
4181 (token_definitions_output, get_lines_number): No longer static.
4182
4183 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
4184
4185 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
4186 parse-skel.y.
4187
4188 * src/parse-skel.y: New file.
4189 * src/scan-skel.l: New file.
4190
4191 2001-12-29 Akim Demaille <akim@epita.fr>
4192
4193 %name-prefix is broken.
4194
4195 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
4196 Adjust all dependencies.
4197 * tests/headers.at (export YYLTYPE): Strengthen this test: use
4198 %name-prefix.
4199
4200 Renaming yylval but not yylloc is not consistent. Now we do.
4201
4202 * src/bison.simple: Prefix yylloc if used.
4203 * doc/bison.texinfo (Decl Summary): Document that.
4204
4205 2001-12-29 Akim Demaille <akim@epita.fr>
4206
4207 * doc/bison.texinfo: Promote `%long-directive' over
4208 `%long_directive'.
4209 Remove all references to fixed-output-files, yacc is enough.
4210
4211 2001-12-29 Akim Demaille <akim@epita.fr>
4212
4213 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
4214 user prologue. These are defaults.
4215 * tests/actions.at (Mid-rule actions): Make sure the user can
4216 define YYDEBUG and YYERROR_VERBOSE.
4217
4218 2001-12-29 Akim Demaille <akim@epita.fr>
4219
4220 * src/output.c (header_output): Don't forget to export YYLTYPE and
4221 yylloc.
4222 * tests/headers.at (export YYLTYPE): New, make sure it does.
4223 * tests/regression.at (%union and --defines, Invalid CPP headers):
4224 Move to...
4225 * tests/headers.at: here.
4226
4227 2001-12-29 Akim Demaille <akim@epita.fr>
4228
4229 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
4230
4231 2001-12-29 Akim Demaille <akim@epita.fr>
4232
4233 * tests/actions.at (Mid-rule actions): Output on a single line
4234 instead of several.
4235
4236 2001-12-29 Akim Demaille <akim@epita.fr>
4237
4238 * doc/bison.texinfo: Formatting changes.
4239
4240 2001-12-29 Akim Demaille <akim@epita.fr>
4241
4242 Don't store the token defs in a muscle, just be ready to output it
4243 on command. Now possible via `symbols'. Fixes a memory leak.
4244
4245 * src/output.c (token_definitions_output): New.
4246 (output_parser, header_output): Use it.
4247 * src/reader.c (symbols_save): Remove.
4248
4249 2001-12-29 Akim Demaille <akim@epita.fr>
4250
4251 * src/bison.simple: Do not provide a default for YYSTYPE and
4252 YYLTYPE before the user's prologue. Otherwise it's hardly... a
4253 default.
4254
4255 2001-12-29 Akim Demaille <akim@epita.fr>
4256
4257 Mid-rule actions are simply... ignored!
4258
4259 * src/reader.c (readgram): Be sure to attach mid-rule actions to
4260 the empty-rule associated to the dummy symbol, not to the host
4261 rule.
4262 * tests/actions.at (Mid-rule actions): New.
4263
4264 2001-12-29 Akim Demaille <akim@epita.fr>
4265
4266 Memory leak.
4267
4268 * src/reader.c (reader): Free grammar.
4269
4270 2001-12-29 Akim Demaille <akim@epita.fr>
4271
4272 Memory leak.
4273
4274 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
4275 since it allocates it for each state, although only one is needed.
4276 (allocate_storage): Do it here.
4277
4278 2001-12-29 Akim Demaille <akim@epita.fr>
4279
4280 * src/options.h, src/options.c (create_long_option_table): Rename
4281 as...
4282 (long_option_table_new): this, with a clearer prototype.
4283 (percent_table): Remove, unused,
4284 * src/getargs.c (getargs): Adjust.
4285
4286 2001-12-29 Akim Demaille <akim@epita.fr>
4287
4288 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
4289 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
4290 as states.
4291
4292 2001-12-29 Akim Demaille <akim@epita.fr>
4293
4294 * src/lalr.c (build_relations): Rename `states' as `states1'.
4295 Sorry, I don't understand exactly what it is, no better name...
4296
4297 2001-12-29 Akim Demaille <akim@epita.fr>
4298
4299 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
4300 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
4301 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
4302 as rules.
4303
4304 2001-12-29 Akim Demaille <akim@epita.fr>
4305
4306 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
4307 ago.
4308
4309 2001-12-29 Akim Demaille <akim@epita.fr>
4310
4311 * src/reader.c, src/reader.h (user_toknums): Remove.
4312 Adjust all users to use symbols[i]->user_token_number.
4313
4314 2001-12-29 Akim Demaille <akim@epita.fr>
4315
4316 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
4317 Adjust all users to use symbols[i]->prec or ->assoc.
4318
4319 2001-12-29 Akim Demaille <akim@epita.fr>
4320
4321 * src/reader.c, src/reader.h (tags): Remove.
4322 Adjust all users to use symbols[i]->tag.
4323
4324 2001-12-29 Akim Demaille <akim@epita.fr>
4325
4326 * src/gram.h, src/gram.c (symbols): New, similar to state_table
4327 and rule_table.
4328 * src/reader.c (packsymbols): Fill this table.
4329 Drop sprec.
4330 * src/conflicts.c (resolve_sr_conflict): Adjust.
4331 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
4332 single table.
4333 Use symbols[i]->tag instead of tags[i].
4334
4335 2001-12-29 Akim Demaille <akim@epita.fr>
4336
4337 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
4338 In addition, put a comment in there, to replace...
4339 * tests/regression.at (%union and C comments): Remove.
4340
4341 2001-12-29 Akim Demaille <akim@epita.fr>
4342
4343 * tests/regression.at (Web2c Actions): Blindly move the actual
4344 output as expected output. The contents *seem* right to me, but I
4345 can't pretend reading perfectly parser tables... Nonetheless, all
4346 the other tests pass correctly, the table look OK, even though the
4347 presence of `$axiom' is to be noted: AFAICS it is useless (but
4348 harmless).
4349
4350 2001-12-29 Akim Demaille <akim@epita.fr>
4351
4352 * src/reader.c (readgram): Don't add the rule 0 if there were no
4353 rules read. In other words, add it _after_ having performed
4354 grammar sanity checks.
4355 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
4356
4357 2001-12-29 Akim Demaille <akim@epita.fr>
4358
4359 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
4360 visible, and some states have now a different number.
4361
4362 2001-12-29 Akim Demaille <akim@epita.fr>
4363
4364 * src/reader.c (readgram): Bind the initial rule's lineno to that
4365 of the first rule.
4366 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
4367 (Solved SR Conflicts): Adjust rule 0's line number.
4368
4369 2001-12-29 Akim Demaille <akim@epita.fr>
4370
4371 Fix the `GAWK Grammar' failure.
4372
4373 * src/LR0.c (final_state): Initialize to -1 so that we do compute
4374 the reductions of the first state which was mistakenly confused
4375 with the final state because precisely final_state was initialized
4376 to 0.
4377 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
4378 now noticed by Bison.
4379 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
4380 have a reduction on $default.
4381
4382 2001-12-29 Akim Demaille <akim@epita.fr>
4383
4384 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
4385 rule line numbers.
4386 * src/closure.c (print_closure): Likewise.
4387 * src/derives.c (print_derives): Likewise.
4388 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
4389 now.
4390
4391 2001-12-29 Akim Demaille <akim@epita.fr>
4392
4393 * src/lalr.c (lookaheads_print): New.
4394 (lalr): Call it when --trace-flag.
4395 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
4396 are dumped.
4397
4398 2001-12-29 Akim Demaille <akim@epita.fr>
4399
4400 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
4401 when walking through ritem, even via rule->rhs.
4402 * src/reduce.c (dump_grammar, useful_production, reduce_output)
4403 (useful_production, useless_nonterminals): Likewise.
4404 (reduce_grammar_tables): Likewise, plus update nritems.
4405 * src/nullable.c (set_nullable): Likewise.
4406 * src/lalr.c (build_relations): Likewise.
4407 * tests/sets.at (Nullable): Adjust.
4408 Fortunately, now, the $axiom is no longer nullable.
4409
4410 2001-12-29 Akim Demaille <akim@epita.fr>
4411
4412 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
4413 the 0-sentinel.
4414 * src/gram.c (ritem_longest_rhs): Likewise.
4415 * src/reduce.c (nonterminals_reduce): Likewise.
4416 * src/print_graph.c (print_graph): Likewise.
4417 * src/output.c (output_rule_data): Likewise.
4418 * src/nullable.c (set_nullable): Likewise.
4419
4420 2001-12-29 Akim Demaille <akim@epita.fr>
4421
4422 * src/output.c: Comment changes.
4423
4424 2001-12-27 Paul Eggert <eggert@twinsun.com>
4425
4426 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
4427 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
4428 Sparc, as they were causing more porting problems than the
4429 (minor) performance improvement was worth.
4430
4431 Also, catch up with 1.31's YYSTD.
4432
4433 2001-12-27 Akim Demaille <akim@epita.fr>
4434
4435 * src/output.c (output_gram): Rely on nritems, not the
4436 0-sentinel. See below.
4437 Use -1 as separator, not 0.
4438 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
4439 Rely on -1 as separator in yyrhs, instead of 0.
4440 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
4441 twice `Now at end of input', therefore there are two lines less to
4442 expect.
4443
4444 2001-12-27 Akim Demaille <akim@epita.fr>
4445
4446 * tests/regression.at (Unresolved SR Conflicts):
4447 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
4448 below.
4449
4450 2001-12-27 Akim Demaille <akim@epita.fr>
4451
4452 * src/LR0.c (new_state): Recognize the final state by the fact it
4453 is reached by eoftoken.
4454 (insert_start_shifting_state, insert_eof_shifting_state)
4455 (insert_accepting_state, augment_automaton): Remove, since now
4456 these states are automatically computed from the initial state.
4457 (generate_states): Adjust.
4458 * src/print.c: When reporting a rule number to the user, substract
4459 1, so that the axiom rule is rule 0, and the first user rule is 1.
4460 * src/reduce.c: Likewise.
4461 * src/print_graph.c (print_core): For the time being, just as for
4462 the report, depend upon --trace-flags to dump the full set of
4463 items.
4464 * src/reader.c (readgram): Once the grammar read, insert the rule
4465 0: `$axiom: START-SYMBOL $'.
4466 * tests/set.at: Adjust: rule 0 is now displayed, and since the
4467 number of the states has changed (the final state is no longer
4468 necessarily the last), catch up.
4469
4470 2001-12-27 Akim Demaille <akim@epita.fr>
4471
4472 Try to make the use of the eoftoken valid. Given that its value
4473 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
4474 is used instead of > 0 where appropriate, (ii), depend upon nritems
4475 instead of the 0-sentinel.
4476
4477 * src/gram.h, src/gram.c (nritems): New.
4478 Expected to be duplication of nitems, but for the time being...
4479 * src/reader.c (packgram): Assert nritems and nitems are equal.
4480 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
4481 * src/closure.c (print_closure, print_fderives): Likewise.
4482 * src/gram.c (ritem_print): Likewise.
4483 * src/print.c (print_core, print_grammar): Likewise.
4484 * src/print_graph.c: Likewise.
4485
4486 2001-12-27 Akim Demaille <akim@epita.fr>
4487
4488 * src/main.c (main): If there are complains after grammar
4489 reductions, then output the report anyway if requested, then die.
4490 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
4491 * src/reader.c (eoftoken): New.
4492 (parse_token_decl): If the token being defined has value `0', it
4493 is the eoftoken.
4494 (packsymbols): No longer hack `tags' to insert `$' by hand.
4495 Be sure to preserve the value of the eoftoken.
4496 (reader): Make sure eoftoken is defined.
4497 Initialize nsyms to 0: now eoftoken is created just like the others.
4498 * src/print.c (print_grammar): Don't special case the eof token.
4499 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
4500 lie anyway, albeit pleasant.
4501 * tests/calc.at: Exercise error messages with eoftoken.
4502 Change the grammar so that empty input is invalid.
4503 Adjust expectations.
4504 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
4505
4506 2001-12-27 Akim Demaille <akim@epita.fr>
4507
4508 * configure.in: Check the protos of strchr ans strspn.
4509 Replace strchr if needed.
4510 * src/system.h: Provide the protos of strchr, strspn and memchr if
4511 missing.
4512 * lib/strchr.c: New.
4513 * src/reader.c (symbols_save): Use strchr.
4514
4515 2001-12-27 Akim Demaille <akim@epita.fr>
4516
4517 * src/print.c, src/print_graph.c (escape): New.
4518 Use it to quote the TAGS outputs.
4519 * src/print_graph.c (print_state): Now errors are in red, and
4520 reductions in green.
4521 Prefer high to wide: output the state number on a line of its own.
4522
4523 2001-12-27 Akim Demaille <akim@epita.fr>
4524
4525 * src/state.h, src/state.c (reductions_new): New.
4526 * src/LR0.c (set_state_table): Let all the states have a
4527 `reductions', even if reduced to 0.
4528 (save_reductions): Adjust.
4529 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
4530 * src/print.c (print_reductions, print_actions): Adjust.
4531 * src/output.c (action_row): Adjust.
4532
4533 2001-12-27 Akim Demaille <akim@epita.fr>
4534
4535 * src/state.h, src/state.c (errs_new, errs_dup): New.
4536 * src/LR0.c (set_state_table): Let all the states have an errs,
4537 even if reduced to 0.
4538 * src/print.c (print_errs, print_reductions): Adjust.
4539 * src/output.c (output_actions, action_row): Adjust.

4545
4546 2001-12-27 Akim Demaille <akim@epita.fr>
4547
4548 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...

4550 (lookaheadset, shiftset): New, used as additional storage by
4551 print_reductions.
4552 (print_results): Adjust.
4553 (print_shifts, print_gotos, print_errs): New, extracted from...
4554 (print_actions): here.
4555 * src/print_graph.c (print_actions): Remove dead code.
4556
4557 2001-12-27 Akim Demaille <akim@epita.fr>
4558
4559 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
4560 `$n' and `@n'.
4561
4562 2001-12-27 Akim Demaille <akim@epita.fr>
4563
4564 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
4565 (build_relations): Adjust.
4566
4567 2001-12-27 Akim Demaille <akim@epita.fr>
4568
4569 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
4570 duplication.
4571
4572 2001-12-27 Akim Demaille <akim@epita.fr>
4573
4574 * src/reader.c (packgram): Catch nitems overflows.
4575
4576 2001-12-27 Akim Demaille <akim@epita.fr>
4577
4578 * src/files.c, src/files.h (guard_obstack): Remove.
4579 * src/output.c (output): Adjust.
4580 * src/reader.c (parse_braces): New, factoring...
4581 (copy_action, copy_guard): these two which are renamed as...
4582 (parse_action, parse_guard): these.
4583 As a voluntary consequence, using braces around guards is now
4584 mandatory.
4585
4586 2001-12-27 Akim Demaille <akim@epita.fr>
4587
4588 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
4589 * src/reader.c (symbol_list): `guard' and `guard_line' are new
4590 members.
4591 (symbol_list_new): Adjust.
4592 (copy_action): action_line is the first line, not the last.
4593 (copy_guard): Just as for actions, store the `action' only, not
4594 the switch/case/break flesh.
4595 Don't parse the user action that might follow the guard, let...
4596 (readgram): do it, i.e., now, there can be an action after a
4597 guard.
4598 In other words the guard is just explicitly optional.
4599 (packgram): Adjust.
4600 * src/output.c (guards_output): New.
4601 (output_parser): Call it when needed.
4602 (output): Also free the guard and attrs obstacks.
4603 * src/files.c, src/files.h (obstack_save): Remove.
4604 (output_files): Remove.
4605 As a result, if one needs the former `.act' file, using an
4606 appropriate skeleton which requires actions and guards is now
4607 required.
4608 * src/main.c (main): Adjust.
4609 * tests/semantic.at: New.
4610 * tests/regression.at: Use `input.y' as input file name.
4611 Avoid 8+3 problems by requiring input.c when the test needs the
4612 parser.
4613
4614 2001-12-27 Akim Demaille <akim@epita.fr>
4615
4616 * src/reader.c (symbol_list_new): Be sure to initialize all the
4617 fields.
4618
4619 2001-12-27 Akim Demaille <akim@epita.fr>
4620
4621 All the hacks using a final pseudo state are now useless.
4622
4623 * src/LR0.c (set_state_table): state_table holds exactly nstates.
4624 * src/lalr.c (nLA): New.
4625 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
4626 instead of lookaheadsp from the pseudo state (nstate + 1).
4627
4628 2001-12-27 Akim Demaille <akim@epita.fr>
4629
4630 * src/output.c (action_row, token_actions): Use a state_t instead
4631 of a integer, and nlookaheads instead of the following state's
4632 lookaheadsp.
4633
4634 2001-12-27 Akim Demaille <akim@epita.fr>
4635
4636 * src/conflicts.c (log_resolution, flush_shift)
4637 (resolve_sr_conflict, set_conflicts, solve_conflicts)
4638 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
4639 (conflicts_print, print_reductions): Use a state_t instead of an
4640 integer when referring to a state.
4641 As much as possible, depend upon nlookaheads, instead of the
4642 `lookaheadsp' member of the following state (since lookaheads of
4643 successive states are successive, the difference between state n + 1
4644 and n served as the number of lookaheads for state n).
4645 * src/lalr.c (add_lookback_edge): Likewise.
4646 * src/print.c (print_core, print_actions, print_state)
4647 (print_results): Likewise.
4648 * src/print_graph.c (print_core, print_actions, print_state)
4649 (print_graph): Likewise.

4651
4652 2001-12-27 Akim Demaille <akim@epita.fr>
4653
4654 * src/bison.hairy: Formatting/comment changes.
4655 ANSIfy.
4656 Remove `register' indications.
4657 Add plenty of `static'.
4658
4659 2001-12-27 Akim Demaille <akim@epita.fr>
4660
4661 * src/output.c (prepare): Drop the muscle `ntbase' which
4662 duplicates ntokens.
4663 * src/bison.simple: Formatting/comment changes.
4664 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
4665 is an undocumented synonym.
4666
4667 2001-12-22 Akim Demaille <akim@epita.fr>
4668
4669 * src/output.c (output_table_data): Change the prototype to use
4670 `int' for array ranges: some invocations do pass an int, not a
4671 short.
4672 Reported by Wayne Green.
4673
4674 2001-12-22 Akim Demaille <akim@epita.fr>
4675
4676 Some actions of web2c.y are improperly triggered.
4677 Reported by Mike Castle.
4678
4679 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
4680 * tests/regression.at (Web2c): Rename as...
4681 (Web2c Report): this.
4682 (Web2c Actions): New.
4683
4684 2001-12-22 Akim Demaille <akim@epita.fr>
4685
4686 Reductions in web2c.y are improperly reported.
4687 Reported by Mike Castle.

4690 * tests/regression.at (Web2c): New.
4691
4692 2001-12-18 Akim Demaille <akim@epita.fr>
4693
4694 Some host fail on `assert (!"foo")', which expands to
4695 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
4696 Reported by Nelson Beebee.
4697
4698 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
4699 `#define it_succeeded 0' and `assert (it_succeeded)'.
4700
4701 2001-12-17 Marc Autret <autret_m@epita.fr>
4702
4703 * src/bison.simple: Don't hard code the skeleton line and filename.
4704 * src/output.c (output_parser): Rename 'line' as 'output_line'.
4705 New line counter 'skeleton_line' (skeleton-line muscle).
4706
4707 2001-12-17 Paul Eggert <eggert@twinsun.com>
4708
4709 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
4710 YYDEBUG must be defined to a nonzero value.
4711
4712 * src/bison.simple (yytname): Do not assume that the user defines
4713 YYDEBUG to a properly parenthesized expression.
4714
4715 2001-12-17 Akim Demaille <akim@epita.fr>
4716
4717 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
4718 nlookaheads is a new member.
4719 Adjust all users.
4720 * src/lalr.h (nlookaheads): Remove this orphan declaration.
4721 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
4722 state.
4723
4724 2001-12-17 Akim Demaille <akim@epita.fr>
4725
4726 * src/files.h, src/files.c (open_files, close_files): Remove.
4727 * src/main.c (main): Don't open/close files, nor invoke lex_free,
4728 let...
4729 * src/reader.c (reader): Do it.

4742
4743 * src/output.c (output_obstack): Be static and rename as...
4744 (format_obstack): this, to avoid any confusion with files.c's
4745 output_obstack.
4746 * src/reader.h (muscle_obstack): Move to...
4747 * src/output.h: here, since it's defined in output.c.
4748
4749 2001-12-17 Akim Demaille <akim@epita.fr>
4750
4751 * src/output.c (action_row, save_column, default_goto)
4752 (sort_actions, matching_state, pack_vector): Better variable
4753 locality.
4754
4755 2001-12-17 Akim Demaille <akim@epita.fr>
4756
4757 * src/output.c: Various formatting changes.
4758
4759 2001-12-17 Akim Demaille <akim@epita.fr>
4760
4761 * src/files.c (output_files): Free the output_obstack.
4762 * src/main.c (main): Call print and print_graph conditionally.
4763 * src/print.c (print): Work unconditionally.
4764 * src/print_graph.c (print_graph): Work unconditionally.
4765 * src/conflicts.c (log_resolution): Output only if verbose_flag.
4766
4767 2001-12-16 Marc Autret <autret_m@epita.fr>
4768
4769 * src/output.c (actions_output): Fix. When we use %no-lines,
4770 there is one less line per action.
4771
4772 2001-12-16 Marc Autret <autret_m@epita.fr>
4773
4774 * src/bison.simple: Remove a useless #line directive.
4775 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4776 * src/output.c (get_lines_number): New.
4777 (output_parser): Adjust, now takes care about the lines of a
4778 output muscles.
4779 Fix line numbering.
4780 (actions_output): Computes the number of lines taken by actions.
4781 (output_master_parser): Insert new skeleton which is the name of
4782 the output parser file name.
4783
4784 2001-12-15 Marc Autret <autret_m@epita.fr>

4793
4794 Make `make distcheck' work.
4795
4796 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4797 system.h which uses libgettext.h.
4798
4799 2001-12-15 Akim Demaille <akim@epita.fr>
4800
4801 * src/nullable.c (set_nullable): Useless rules must be skipped,
4802 otherwise, since we range over their symbols, we might look at a
4803 nonterminal which no longer ``exists'', i.e., it is not counted in
4804 `nvars', hence we overflow our arrays.
4805
4806 2001-12-15 Akim Demaille <akim@epita.fr>
4807
4808 The header can also be produced directly, without any obstack!
4809 Yahoo!
4810
4811 * src/files.c, src/files.h (defines_obstack): Remove.
4812 (compute_header_macro): Global.
4813 (defines_obstack_save): Remove.
4814 * src/reader.c (parse_union_decl): No longer output to
4815 defines_obstack: its content can be found in the `stype' muscle
4816 anyway.
4817 (output_token_translations): Merge into...
4818 (symbols_output): this.
4819 Rename as...
4820 (symbols_save): this.
4821 (reader): Adjust.
4822 * src/output.c (header_output): New.
4823 (output): Call it.
4824
4825 2001-12-15 Akim Demaille <akim@epita.fr>
4826
4827 * src/reader.c (parse_union_decl): Instead of handling two obstack
4828 simultaneously, use one to define the `stype' muscle, and use the
4829 value of the latter to fill defines_obstack.
4830 (copy_comment): Remove.
4831 (copy_comment2): Work for a single obstack.
4832 Rename as...
4833 (copy_comment): this.
4834
4835 2001-12-15 Akim Demaille <akim@epita.fr>
4836
4837 * src/lex.c, src/lex.h (xgetc): No longer static.
4838 * src/reader.c (parse_union_decl): Revamp.
4839
4840 2001-12-15 Akim Demaille <akim@epita.fr>
4841
4842 Still making progress in separating Bison into (i) input, (ii)
4843 process, (iii) output: now we can directly output the parser file
4844 without using table_obstack at all.
4845
4846 * src/files.c, src/files.h (table_obstack): Bye bye.
4847 (parser_file_name): New.
4848 * src/files.c (compute_output_file_names): Compute it.
4849 * src/output.c (actions_output, output_parser)
4850 (output_master_parser): To a file instead of an obstack.
4851
4852 2001-12-15 Akim Demaille <akim@epita.fr>
4853
4854 Attach actions to rules, instead of pre-outputting them to
4855 actions_obstack.
4856
4857 * src/gram.h (rule_t): action and action_line are new members.
4858 * src/reader.c (symbol_list): Likewise.
4859 (copy_action): Save the actions within the rule.
4860 (packgram): Save them in rule_table.
4861 * src/output.c (actions_output): New.
4862 (output_parser): Use it on `%%actions'.
4863 (output_rule_data): Don't free rule_table.
4864 (output): Do it.
4865 (prepare): Don't save the `action' muscle.
4866 * src/bison.simple: s/%%action/%%actions/.
4867
4868 2001-12-15 Akim Demaille <akim@epita.fr>
4869
4870 * src/reader.c (copy_action): When --yacc, don't append a `;'
4871 to the user action: let it fail if lacking.
4872 Suggested by Arnold Robbins and Tom Tromey.
4873
4874 2001-12-14 Akim Demaille <akim@epita.fr>
4875
4876 * src/lex.c (literalchar): Simply return the char you decoded, non
4877 longer mess around with obstacks and int pointers.
4878 Adjust all callers.
4879
4880 2001-12-14 Akim Demaille <akim@epita.fr>
4881
4882 * src/lex.c (literalchar): Don't escape the special characters,
4883 just decode them, and keep them as char (before, eol was output as
4884 the 2 char string `\n' etc.).
4885 * src/output.c (output_rule_data): Use quotearg to output the
4886 token strings.
4887
4888 2001-12-13 Paul Eggert <eggert@twinsun.com>
4889
4890 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4891 Do not infringe on the global user namespace when using C++.
4892 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4893 All uses of `fprintf' and `stderr' changed.
4894
4895 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4896
4897 2001-12-13 Akim Demaille <akim@epita.fr>
4898
4899 The computation of nullable is broken: it doesn't handle empty
4900 RHS's properly.
4901
4902 * tests/torture.at (GNU AWK Grammar): New.
4903 * tests/sets.at (Nullable): New.
4904 * src/nullable.c (set_nullable): Instead of blindly looping over
4905 `ritems', loop over the rules, and then over their rhs's.
4906
4907 Work around Autotest bugs.
4908
4909 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4910 frame, because Autotest understand lines starting with a `+' as
4911 traces from the shell. Then, they are not processed properly.
4912 Admittedly an Autotest bug, but we don't have time to wait for
4913 Autotest to catch up.
4914 * tests/regression.at (Broken Closure): Adjust to the new table
4915 frames.
4916 Move to...
4917 * tests/sets.at: here.
4918
4919 2001-12-13 Akim Demaille <akim@epita.fr>
4920
4921 * src/closure.c (closure): Use nrules instead of playing tricks
4922 with BITS_PER_WORD.
4923
4924 2001-12-13 Akim Demaille <akim@epita.fr>
4925
4926 * src/print.c (print_actions): Output the handling of `$' as the
4927 traces do: shifting the token EOF. Before EOF was treated as a
4928 nonterminal.
4929 * tests/regression.at: Adjust some tests.
4930 * src/print_graph.c (print_core): Complete the set of items via
4931 closure. The next-to-final and final states are still unsatisfying,
4932 but that's to be addressed elsewhere.
4933 No longer output the rule numbers, but do output the state number.
4934 A single loop for the shifts + gotos is enough, but picked a
4935 distinct color for each.
4936 (print_graph): Initialize and finalize closure.
4937
4938 2001-12-13 Akim Demaille <akim@epita.fr>
4939
4940 * src/reader.c (readgram): Remove dead code, an strip useless
4941 braces.
4942 (get_type): Remove, unused.
4943
4944 2001-12-12 Akim Demaille <akim@epita.fr>
4945
4946 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4947 on that of lib/error.c.
4948
4949 2001-12-12 Akim Demaille <akim@epita.fr>
4950
4951 Some hosts don't like `/' in includes.
4952
4953 * src/system.h: Include libgettext.h without qualifying the path.
4954 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4955 $(top_srcdir).
4956
4957 2001-12-11 Marc Autret <autret_m@epita.fr>
4958
4959 * src/output.c (output_parser): Remove useless muscle.
4960
4961 2001-12-11 Marc Autret <autret_m@epita.fr>
4962
4963 * src/bison.simple: Remove #line just before %%epilogue. It
4964 is now handled in ...
4965 * src/reader.c (read_additionnal_code): Add the output of a
4966 #line for the epilogue.
4967
4968 2001-12-10 Marc Autret <autret_m@epita.fr>
4969
4970 * src/reader.c (copy_definition): Re-use CPP-outed code which
4971 replace precedent remove.
4972 * src/bison.simple: Remove #line before %%prologue because
4973 %%input-line is wrong at this time.
4974
4975 2001-12-10 Marc Autret <autret_m@epita.fr>
4976
4977 * src/reader.c (symbols_output): Clean up.
4978 * src/output.c (output_gram, output): Clean up.
4979
4980 2001-12-10 Akim Demaille <akim@epita.fr>
4981
4982 * src/lalr.c (initialize_lookaheads): New. Extracted from...
4983 * src/LR0.c (set_state_table): here.
4984 * src/lalr.c (lalr): Call it.
4985
4986 2001-12-10 Akim Demaille <akim@epita.fr>
4987
4988 * src/state.h (shifts): Remove the `number' member: shifts are
4989 attached to state, hence no longer need to be labelled with a
4990 state number.
4991
4992 2001-12-10 Akim Demaille <akim@epita.fr>
4993
4994 Now that states have a complete set of members, the linked list of
4995 shifts is useless: just fill directly the state's shifts member.
4996
4997 * src/state.h (shifts): Remove the `next' member.
4998 * src/LR0.c (first_state, last_state): Remove.
4999 Adjust the callers.
5000 (augment_automaton): Don't look for the shifts that must be added
5001 a shift on EOF: it is those of the state we looked for! But now,
5002 since shifts are attached, it is no longer needed to looking
5003 merely by its id: its number.
5004
5005 2001-12-10 Akim Demaille <akim@epita.fr>
5006
5007 * src/LR0.c (augment_automaton): Better variable locality.
5008 Remove an impossible branch: if there is a state corresponding to
5009 the start symbol being shifted, then there is shift for the start
5010 symbol from the initial state.
5011
5012 2001-12-10 Akim Demaille <akim@epita.fr>
5013
5014 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
5015 only when appropriate: when insert_start_shifting_state' is not
5016 invoked.
5017 * tests/regression.at (Rule Line Numbers): Adjust.
5018
5019 2001-12-10 Akim Demaille <akim@epita.fr>
5020
5021 * src/LR0.c (augment_automaton): Now that all states have shifts,
5022 merge the two cases addition shifts to the initial state.
5023
5024 2001-12-10 Akim Demaille <akim@epita.fr>
5025
5026 * src/lalr.c (set_state_table): Move to...
5027 * src/LR0.c: here.
5028 * src/lalr.c (lalr): Don't call it...
5029 * src/LR0.c (generate_states): do it.
5030 * src/LR0.h (first_state): Remove, only the table is used.
5031
5032 2001-12-10 Akim Demaille <akim@epita.fr>
5033
5034 * src/LR0.h (first_shift, first_reduction): Remove.
5035 * src/lalr.c: Don't use first_shift: find shifts through the
5036 states.
5037
5038 2001-12-10 Akim Demaille <akim@epita.fr>
5039
5040 * src/LR0.c: Attach shifts to states as soon as they are
5041 computed.
5042 * src/lalr.c (set_state_table): Instead of assigning shifts to
5043 state, just assert that the mapping was properly done.
5044
5045 2001-12-10 Akim Demaille <akim@epita.fr>
5046
5047 * src/LR0.c (insert_start_shift): Rename as...
5048 (insert_start_shifting_state): this.
5049 (insert_eof_shifting_state, insert_accepting_state): New.
5050 (augment_automaton): Adjust.
5051 Better locality of the variables.
5052 When looking if the start_symbol is shifted from the initial
5053 state, using `while (... symbol != start_symbol ...)' sounds
5054 better than `while (... symbol < start_symbol ...)': If fail
5055 to see how the order between symbols could be relevant!
5056
5057 2001-12-10 Akim Demaille <akim@epita.fr>
5058
5059 * src/getargs.h: Don't declare `spec_name_prefix' and
5060 `spec_file_prefix', declared by src/files.h.
5061 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
5062 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
5063 * src/output.c (prepare): Adjust.
5064 * src/reader.c (symbols_output): Likewise.
5065 * src/vmsgetargs.c: Vaguely adjust, but who cares?
5066
5067 2001-12-10 Akim Demaille <akim@epita.fr>
5068
5069 * src/muscle_tab.c (muscle_init): NULL is a better default than
5070 `"0"'.
5071
5072 2001-12-10 Akim Demaille <akim@epita.fr>
5073
5074 * src/reader.c (reader): Calling symbols_output once is enough.
5075
5076 2001-12-10 Akim Demaille <akim@epita.fr>
5077
5078 Now that states have a complete set of members, the linked list of
5079 reductions is useless: just fill directly the state's reductions
5080 member.
5081
5082 * src/state.h (struct reductions): Remove member `number' and
5083 `next'.
5084 * src/LR0.c (first_reduction, last_reduction): Remove.
5085 (save_reductions): Don't link the new reductions, store them in
5086 this_state.
5087 * src/lalr.c (set_state_table): No need to attach reductions to
5088 states, it's already done.
5089 * src/output.c (output_actions): No longer free the shifts, then
5090 the reductions, then the states: free all the states and their
5091 members.
5092
5093 2001-12-10 Akim Demaille <akim@epita.fr>
5094
5095 * src/options.c (OPTN, DRTV, BOTH): New.
5096 (option_table): Use them.
5097
5098 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
5099 the job of system.h.
5100 * src/options.c: Don't include stdio.h and xalloc.h for the same
5101 reasons.
5102
5103 2001-12-10 Akim Demaille <akim@epita.fr>
5104
5105 * src/output.c (output, prepare): Make sure the values of the
5106 muscles `action' and `prologue' are 0-terminated.
5107
5108 2001-12-10 Akim Demaille <akim@epita.fr>
5109
5110 Clean up GCC warnings.
5111
5112 * src/reader.c (copy_action): `buf' is not used.
5113 (parse_skel_decl): Be static.
5114 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
5115 * src/options.h (create_long_option_table): Have a real prototype.
5116 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
5117 (hash_delete_at): Return const void *.
5118 Adjust casts to preserve the const.
5119
5120 2001-12-10 Akim Demaille <akim@epita.fr>
5121
5122 * configure.in: Require 2.52g.
5123 M4 is not needed, but AUTOM4TE is.
5124 * m4/m4.m4: Remove.
5125 * tests/Makefile.am: Adjust.
5126
5127 2001-12-10 Akim Demaille <akim@epita.fr>
5128
5129 One structure for states is enough, even though theoretically
5130 there are LR(0) states and LALR(1) states.
5131
5132 * src/lalr.h (state_t): Remove.
5133 (state_table): Be state_t **, not state_t *.
5134 * src/state.h (core, CORE_ALLOC): Rename as...
5135 (state_t, STATE_ALLOC): this.
5136 Add the LALR(1) members: shifts, reductions, errs.
5137 * src/LR0.c (state_table): Rename as...
5138 (state_hash): this, to avoid name clashes with the global
5139 `state_table'.
5140 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
5141 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
5142
5143 2001-12-10 Akim Demaille <akim@epita.fr>
5144
5145 Bison dumps core on bash.y.
5146 Reported by Pascal Bart.
5147
5148 * src/warshall.c (bitmatrix_print): New.
5149 (TC): Use it.
5150 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
5151 j must be the outer loop.
5152 * tests/regression.at (Broken Closure): New.
5153
5154 2001-12-05 Akim Demaille <akim@epita.fr>
5155
5156 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
5157 its argument.
5158 Reported by Peter Hámorský.
5159
5160 2001-12-05 Akim Demaille <akim@epita.fr>
5161
5162 * src/conflicts.c (err_table): Remove.
5163 (resolve_sr_conflict): Adjust.
5164 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
5165 Rename as...
5166 (state_t.reductions, state_t.shifts): this.
5167
5168 2001-12-05 Akim Demaille <akim@epita.fr>
5169
5170 * src/reduce.c (reduce_grammar_tables): No longer disable the
5171 removal of useless rules via CPP but via `if (0)', so that the
5172 compiler still check the code is valid.
5173 For instance, it should have noticed `rline' no longer exists: use
5174 the `line' member of rule_t.
5175 * src/gram.c (dummy, rline): Remove, unused.
5176
5177 2001-12-05 Akim Demaille <akim@epita.fr>
5178
5179 * src/output.c (pack_vector): Use assert, not berror.
5180 * src/main.c (berror): Remove, unused.
5181
5182 2001-12-05 Akim Demaille <akim@epita.fr>
5183
5184 New experimental feature: if --verbose --trace output all the
5185 items of a state, not only its kernel.
5186
5187 * src/print.c (print_core): If `trace_flag', then invoke closure
5188 before outputting the items of the state (print_core is no longer
5189 a correct name them).
5190 (print_results): Invoke new_closure/free_closure if needed.
5191
5192 2001-12-05 Akim Demaille <akim@epita.fr>
5193
5194 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
5195 * src/closure.c, src/closure.h (itemsetsize): Rename as...
5196 (nitemset): for consistency with the rest of the project.
5197
5198 2001-12-05 Akim Demaille <akim@epita.fr>
5199
5200 * src/closure.c (print_closure): Improve.
5201 (closure): Use it for printing input and output.
5202
5203 2001-12-05 Akim Demaille <akim@epita.fr>
5204
5205 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
5206 indexed by nonterminals.
5207
5208 2001-12-05 Akim Demaille <akim@epita.fr>
5209
5210 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
5211 what it was!).
5212 * src/warshall.h: Remove accidental duplication of the content.
5213
5214 2001-12-05 Akim Demaille <akim@epita.fr>
5215
5216 * src/closure.c (set_fderives): De-obfuscate.
5217
5218 2001-12-05 Akim Demaille <akim@epita.fr>
5219
5220 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
5221
5222 2001-12-05 Akim Demaille <akim@epita.fr>
5223
5224 * src/closure.c (set_firsts): De-obfuscate.
5225
5226 2001-12-05 Akim Demaille <akim@epita.fr>
5227
5228 * src/output.c (action_row): De-obfuscate
5229 using the good o' techniques: arrays not pointers, variable
5230 locality, BITISSET, RESETBIT etc.
5231
5232 2001-12-05 Akim Demaille <akim@epita.fr>
5233
5234 Pessimize the code to simplify it: from now on, all the states
5235 have a valid SHIFTS, which NSHIFTS is possibly 0.
5236
5237 * src/LR0.c (shifts_new): Be global and move to..
5238 * src/state.c, src/state.h: here.
5239 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
5240 * src/print_graph: Adjust.
5241
5242 2001-12-05 Akim Demaille <akim@epita.fr>
5243
5244 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
5245 * src/conflicts.c: Use it.
5246 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
5247 incorrectly ``simplified''.
5248
5249 2001-12-05 Akim Demaille <akim@epita.fr>
5250
5251 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
5252 using the good o' techniques: arrays not pointers, variable
5253 locality, BITISSET, RESETBIT etc.
5254
5255 2001-12-05 Akim Demaille <akim@epita.fr>

5259
5260 2001-12-05 Akim Demaille <akim@epita.fr>
5261
5262 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
5263 (print_reductions): De-obfuscate using the good o' techniques:
5264 arrays not pointers, variable locality, BITISSET.
5265
5266 2001-12-05 Akim Demaille <akim@epita.fr>
5267
5268 * src/conflicts.c (print_reductions): Arrays, not pointers.

5270
5271 2001-12-05 Akim Demaille <akim@epita.fr>
5272

5286
5287 2001-12-05 Akim Demaille <akim@epita.fr>
5288

5290 * src/lalr.c: Use them.

5296
5297 2001-12-05 Akim Demaille <akim@epita.fr>
5298
5299 * src/lalr.c (matrix_print): New.
5300 (transpose): Use it.
5301 Use arrays instead of pointers.
5302
5303 2001-12-05 Akim Demaille <akim@epita.fr>
5304
5305 * src/lalr.c (maxrhs): Move to...
5306 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
5307 * src/lalr.c (build_relations): Adjust.
5308
5309 2001-12-05 Akim Demaille <akim@epita.fr>
5310
5311 * src/lalr.c (transpose): Free the memory allocated to the
5312 argument, as it is replaced by the results by the unique caller.
5313 (build_relations): Merely invoke transpose: it handles the memory
5314 deallocation.
5315 Improve variable locality.
5316 Avoid variables used as mere abbreviations.
5317 (compute_lookaheads): Use arrays instead of pointers.
5318

5332
5333 * src/lalr.c (traverse): Use arrays instead of pointers.
5334
5335 2001-12-05 Akim Demaille <akim@epita.fr>
5336
5337 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
5338 the handling of squeue.
5339 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5340
5341 2001-12-05 Akim Demaille <akim@epita.fr>
5342
5343 Because useless nonterminals are now kept alive (instead of being
5344 `destroyed'), we now sometimes examine them, and store information
5345 related to them. Hence we need to know their number, and adjust
5346 memory allocations.
5347
5348 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
5349 static.
5350 * src/LR0.c (allocate_itemsets): The memory allocated to
5351 `symbol_count' was used for two different purpose: once to count
5352 the number of occurrences of each symbol, and later reassigned to
5353 `shift_symbol', containing the symbol that can be shifted from a
5354 given state.
5355 Deobfuscate, i.e., allocate, use and free `symbol_count' here
5356 only, and...
5357 (new_itemsets): Allocate `shift_symbol' here.
5358 (allocate_itemsets): symbol_count includes useless nonterminals.
5359 Make room for them.
5360 (free_storage): Use `free', not `XFREE', for pointers that cannot
5361 be null.
5362
5363 2001-12-05 Akim Demaille <akim@epita.fr>
5364
5365 * src/nullable.c (set_nullable): Deobfuscate the handling of
5366 ritem.
5367 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5368
5369 2001-12-05 Akim Demaille <akim@epita.fr>
5370
5371 * src/gram.c, src/gram.h (ritem_print): New.
5372 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
5373 (This useless function was defined only to work around VMS linkers
5374 that can't handle compilation units with variables only).
5375 * src/reduce.c (dump_grammar): Use it to trace the construction of
5376 ritem.
5377
5378 2001-12-04 Paul Eggert <eggert@twinsun.com>
5379
5380 * src/bison.simple (union yyalloc): Change member names
5381 to be the same as the stack names.
5382 (yyparse): yyptr is now union yyalloc *, not char *.
5383 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
5384 and may generate better code on some machines.
5385 (yystpcpy): Use prototype if __STDC__ is defined, not just
5386 if __cplusplus is defined.
5387
5388 2001-11-30 Akim Demaille <akim@epita.fr>
5389
5390 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
5391 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
5392 Gettext doesn't compile cleanly, and dies with -Werror.
5393 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
5394 Include WARNING_CFLAGS here.
5395 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
5396 before being defined.
5397
5398 2001-11-27 Paul Eggert <eggert@twinsun.com>
5399
5400 * lib/quotearg.h (quotearg_n, quotearg_n_style):
5401 First arg is int, not unsigned.
5402 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
5403 (SIZE_MAX, UINT_MAX): New macros.
5404 (quotearg_n_options): Abort if N is negative.
5405 Avoid overflow check on hosts where size_t is 64 bits and int
5406 is 32 bits, as overflow is impossible there.
5407 Fix off-by-one typo that caused unnecessary reallocation.
5408
5409 2001-11-29 Paul Eggert <eggert@twinsun.com>
5410
5411 Name space cleanup in generated parser.
5412
5413 * doc/bison.texinfo (Bison Parser): Discuss system headers
5414 and their effect on the user name space.

5416 * src/bison.simple:
5417 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
5418 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
5419 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
5420
5421 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
5422 on user names when possible.
5423
5424 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
5425 Simplify test for whather <alloca.h> exists.
5426
5427 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
5428
5429 (<stdio.h>): Include if YYDEBUG.
5430
5431 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
5432 ! defined (yyoverflow) && ! defined (yymemcpy).
5433
5434 (yymemcpy, yyparse): Rename local variables as needed so that
5435 they all begin with 'yy'.
5436
5437 (yystrlen, yystpcpy): New functions.
5438
5439 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
5440 All uses changed.
5441
5442 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
5443 instead of relying on string.h functions. Use YYSTACK_ALLOC
5444 and YYSTACK_FREE instead of malloc and free.
5445
5446 2001-11-30 Akim Demaille <akim@epita.fr>

5455
5456 2001-11-30 Akim Demaille <akim@epita.fr>
5457
5458 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
5459 if body instead of `;' to pacify GCC's warnings.
5460
5461 2001-11-30 Akim Demaille <akim@epita.fr>
5462
5463 Instead of mapping the LHS of unused rules to -1, keep the LHS
5464 valid, but flag the rules as invalid.
5465
5466 * src/gram.h (rule_t): `useful' is a new member.
5467 * src/print.c (print_grammar): Adjust.
5468 * src/derives.c (set_derives): Likewise.
5469 * src/reader.c (packgram, reduce_output): Likewise.
5470 * src/reduce.c (reduce_grammar_tables): Likewise.
5471 * tests/reduce.at (Underivable Rules, Useless Rules): New.
5472
5473 2001-11-30 Akim Demaille <akim@epita.fr>

5479
5480 2001-11-30 Akim Demaille <akim@epita.fr>
5481
5482 * src/reduce.c (nonterminals_reduce): Instead of throwing away
5483 useless nonterminals, move them at the end of the symbol arrays.
5484 (reduce_output): Adjust.
5485 * tests/reduce.at (Useless Nonterminals): Adjust.
5486
5487 2001-11-30 Akim Demaille <akim@epita.fr>
5488

5494 2001-11-29 Paul Eggert <eggert@twinsun.com>
5495
5496 * src/bison.simple (YYSTACK_REALLOC): Remove.
5497 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
5498 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
5499 New macros.
5500 (union yyalloc): New type.
5501 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
5502 an arbitrary restriction on hosts where size_t is wider than int.
5503
5504 (yyparse): Don't dump core if alloca or malloc fails; instead, report
5505 a parser stack overflow. Allocate just one block of memory for all
5506 three stacks, instead of allocating three blocks; this typically is
5507 faster and reduces fragmentation.
5508
5509 Do not limit the number of items in the stack to a value that fits
5510 in 'int', as this is an arbitrary limit on hosts with 64-bit
5511 size_t and 32-bit int.
5512
5513 2001-11-29 Marc Autret <autret_m@epita.fr>

5545
5546 * src/bison.simple: Adjust muscle names.

5567
5568 * src/closure.c (closure): Instead of looping over word in array

5572
5573 * src/closure.c (closure): No longer optimize the special case
5574 where all the bits of `ruleset[r]' are set to 0, to make the code
5575 clearer.
5576
5577 2001-11-28 Akim Demaille <akim@epita.fr>
5578
5579 * src/closure.c (closure): `r' and `c' are new variables, used to

5588

5676
5677 2001-11-26 Akim Demaille <akim@epita.fr>

5710 2001-11-23 Akim Demaille <akim@epita.fr>

5967 * src/lex.c (parse_percent_token): Replace equal_offset with

7315

7328 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

7341 (init_lex): Initialize it. No longer call...
7342 (grow_token_buffer): this. Remove it.

7344
7345 2001-01-19 Akim Demaille <akim@epita.fr>
7346
7347 * src/lex.h: Rename all the tokens:
7348 s/\bENDFILE\b/tok_eof/g;

7363 * src/lex.c (percent_table): Also accept `%yacc',
7364 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

7366 Handle the actions for `%semantic_parser' and `%pure_parser' here,
7367 instead of returning a token.
7368 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
7369 * src/reader.c (read_declarations): Adjust.
7370 * src/files.c (open_files): Don't call `compute_base_names', don't
7371 compute `attrsfile' since they depend upon data which might be
7372 *in* the input file now.
7373 (output_files): Do it here.
7374 * src/output.c (output_headers): Document the fact that this patch
7375 introduces a guaranteed SEGV for semantic parsers.
7376 * doc/bison.texinfo: Document them.
7377 * tests/suite.at: Exercise these %options.

7397
7398 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

7400 FILE * parameters.
7401
7402 2000-12-20 Akim Demaille <akim@epita.fr>
7403
7404 * src/files.c (open_files): Actually the `.output' file is based

7432
7433 * src/files.c (strsuffix): New.
7434 (stringappend): Be just like strcat but allocate.
7435 (base_names): Eve out from open_files.
7436 Try to simplify the rather hairy computation of base_name and
7437 short_base_name.
7438 (open_files): Use it.
7439 * tests/suite.at (Checking output file names): New test.
7440

7476
7477 2000-12-19 Akim Demaille <akim@epita.fr>
7478
7479 * src/files.c (open_files): Yipee! We no longer need all the code

7481
7482 2000-12-19 Akim Demaille <akim@epita.fr>
7483

7513 prevents type checking.
7514 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

7564 Qualify it `const'.
7565 (obstack_copy, obstack_copy0): Rename the second argument as

7595 (done): Rename as...
7596 (output_files): this.
7597 Use `obstack_save'.
7598 * src/main.c (main): Don't use `atexit' to register `done', since
7599 it no longer has to remove tmp files, just call `output_files'
7600 when there are no errors.

7670

7672 the `/' which is suspected to open a comment, instead of being
7673 called after `//' or `/*' was read.
7674 (copy_comment, copy_definition, parse_union_decl, copy_action)
7675 (copy_guard): Adjust.
7676

7703 2000-10-04 Akim Demaille <akim@epita.fr>
7704
7705 When a literal string is used to define two different tokens,
7706 `bison -v' segfaults.

7714 2000-10-04 Akim Demaille <akim@epita.fr>
7715
7716 * src/reader.c (parse_expect_decl): Keep `count' within the size
7717 of `buffer'.
7718 From Neil Booth.
7719
7720 2000-10-02 Paul Eggert <eggert@twinsun.com>
7721
7722 * bison.s1 (yyparse): Assign the default value
7723 unconditionally, to avoid a GCC warning and make the parser a
7724 tad smaller.
7725
7726 2000-10-02 Akim Demaille <akim@epita.fr>
7727
7728 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
7729 options.
7730
7731 2000-10-02 Akim Demaille <akim@epita.fr>
7732
7733 * src/derives.c, src/print.c, src/reduce.c: To ease the
7734 translation, move some `\n' out of the translated strings.
7735
7736 2000-10-02 Akim Demaille <akim@epita.fr>
7737
7738 The location tracking mechanism is precious for parse error
7739 messages. Nevertheless, it is enabled only when `@n' is used in
7740 the grammar, which is a different issue (you can use it in error
7741 message, but not in the grammar per se). Therefore, there should
7742 be another means to enable it.
7743
7744 * src/getargs.c (getargs): Support `--locations'.
7745 (usage): Report it.
7746 * src/getargs.h (locationsflag): Export it.
7747 * src/lex.c (percent_table): Support `%locations'.
7748 * src/reader.c (yylsp_needed): Remove this variable, now replaced
7749 with `locationsflag'.
7750 * doc/bison.texinfo: Document `--locations' and `%locations'.
7751 Sort the options.
7752 * tests/calc.m4: Test it.
7753
7754 For regularity of the names, replace each
7755 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
7756 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
7757 In addition replace each `flag' with `_flag'.
7758
7759 2000-10-02 Akim Demaille <akim@epita.fr>
7760
7761 Also test parse error messages, including with YYERROR_VERBOSE.
7762
7763 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
7764 associative).
7765 Use it to check the computations.
7766 Use it to check `nonassoc' is honored.
7767 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
7768 `--yyerror-verbose'.
7769 (_AT_CHECK_CALC): Adjust to this option.
7770 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
7771
7772 2000-10-02 Akim Demaille <akim@epita.fr>
7773
7774 Test also `--verbose', `--defines' and `--name-prefix'. Testing
7775 the latter demonstrates a flaw in the handling of non debugging
7776 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7777 was used in order to simplify:
7778
7779 #if YYDEBUG
7780 if (yydebug)
7781 {
7782 ...
7783 }
7784 #endif
7785
7786 into
7787
7788 if (yydebug)
7789 {
7790 ...
7791 }
7792
7793 unfortunately this leads to a CPP conflict when
7794 `--name-prefix=foo' is used since it produces `#define yydebug
7795 foodebug'.
7796
7797 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7798 (YYDPRINTF): New macro.
7799 Spread its use.
7800 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7801 the bison options.
7802 Also test `--verbose', `--defines' and `--name-prefix'.
7803
7804 2000-10-02 Akim Demaille <akim@epita.fr>
7805
7806 Improve the readability of the produced parsers.
7807
7808 * src/bison.s1: Formatting changes.
7809 Improve the comment related to the `$' mark.
7810 (yydefault): Don't fall through to `yyresume': `goto' there.
7811 * src/output.c (output_parser): When the `$' is met, skip the end
7812 of its line.
7813 New variable, `number_of_dollar_signs', to check there's exactly
7814 one `$' in the parser skeleton.
7815
7816 2000-10-02 Akim Demaille <akim@epita.fr>
7817
7818 * lib/xstrdup.c: New file, from the fileutils.
7819 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
7820 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
7821 instead of strlen + xmalloc + strcpy.
7822 * src/symtab.c (copys): Remove, use xstrdup instead.
7823
7824 2000-10-02 Akim Demaille <akim@epita.fr>
7825
7826 * src/gram.h (associativity): New enum type which replaces the
7827 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
7828 `right_assoc', `left_assoc' and `non_assoc'.
7829 Adjust all dependencies.
7830 * src/reader.c: Formatting changes.
7831 (LTYPESTR): Don't define it, use it as a literal in
7832 `reader_output_yylsp'.
7833 * src/symtab.h (symbol_class): New enum type which replaces the
7834 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
7835 `sunknown', `stoken and `snterm'.
7836
7837 2000-10-02 Akim Demaille <akim@epita.fr>
7838
7839 * src/getargs.c (fixed_outfiles): Rename as...
7840 (yaccflag): for consistency and accuracy.
7841 Adjust dependencies.
7842
7843 2000-10-02 Akim Demaille <akim@epita.fr>
7844
7845 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
7846 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
7847 difficult and introduced a lot of core dump. It turns out that
7848 Bison used an implementation of `xmalloc' based on `calloc', and
7849 at various places it does depend upon the initialization to 0. I
7850 have not tried to isolate the pertinent places, and all the former
7851 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
7852 someone should address this issue.
7853
7854 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
7855 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
7856 files.
7857 Adjust dependencies.

7862
7863 Various anti-`extern in *.c' changes.
7864
7865 * src/system.h: Include `assert.h'.
7866
7867 2000-10-02 Akim Demaille <akim@epita.fr>
7868
7869 * src/state.h (nstates, final_state, first_state, first_shift)
7870 (first_reduction): Move their exportation from here...
7871 * src/LR0.h: to here.
7872 Adjust dependencies.
7873 * src/getargs.c (statisticsflag): New variable.
7874 Add support for `--statistics'.
7875 Adjust dependencies.
7876
7877 Remove a lot of now useless `extern' statements in most files.
7878

7891 Adjust dependencies.
7892
7893 2000-10-02 Akim Demaille <akim@epita.fr>
7894
7895 * src/conflicts.c (conflict_report): New function.
7896 (conflict_log, verbose_conflict_log): Replace with...
7897 (print_conflicts): this function.
7898 Adjust dependencies.
7899 * src/conflicts.h: New file.
7900 Propagate its inclusion.
7901
7902 2000-10-02 Akim Demaille <akim@epita.fr>

7939 (xgetc): this.
7940
7941 2000-10-02 Akim Demaille <akim@epita.fr>
7942
7943 * src/lalr.h: New file.

7946
7947 2000-10-02 Akim Demaille <akim@epita.fr>
7948
7949 * src/output.c (token_actions): Introduce a temporary array,
7950 YYDEFACT, that makes it possible for this function to use
7951 output_short_table.
7952
7953 2000-10-02 Akim Demaille <akim@epita.fr>
7954
7955 `user_toknums' is output as a `short[]' in `output.c', while it is
7956 defined as a `int[]' in `reader.c'. For consistency with the
7957 other output tables, `user_toknums' is now defined as a table of
7958 shorts.
7959
7960 * src/reader.c (user_toknums): Be a short table instead of an int
7961 table.
7962 Adjust dependencies.
7963
7964 Factor the short table outputs.
7965
7966 * src/output.c (output_short_table): New function.
7967 * src/output.c (output_gram, output_stos, output_rule_data)
7968 (output_base, output_table, output_check): Use it.
7969
7970 2000-10-02 Akim Demaille <akim@epita.fr>
7971
7972 * src/output.c (output): Topological sort of the functions, in
7973 order to get rid of the `static' prototypes.
7974 No longer use `register'.
7975 * src/output.h: New file.
7976 Propagate its inclusion in files explicitly prototyping functions
7977 from output.c.
7978
7979 2000-09-21 Akim Demaille <akim@epita.fr>
7980

7997
7998 * src/acconfig.h: Don't protect config.h against multiple
7999 inclusion.
8000 Don't define PARAMS.
8001 * src/system.h: Define PARAMS.
8002 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
8003 purpose of config.h. system.h must not try to fix wrong
8004 definitions in config.h.
8005
8006 2000-09-20 Akim Demaille <akim@epita.fr>
8007
8008 * src/derives.h: New file.

8223 There is now a pseudo variable @$ (readble and writable), location
8224 of the lhs of the rule (by default ranging from the location of
8225 the first symbol of the rhs, to the location of the last symbol,
8226 or, if the rhs is empty, YYLLOC).

8261 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

8266

8993 an incorrect '/'.
8994 (skip_white_space, lex): Revised most error messages

8999
9000 * src/files.c (openfiles, open_extra_files, done):
