49
50 2002-11-03 Paul Eggert <eggert@twinsun.com>
51
52 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,

54
55 Use mbsnwidth to count columns correctly. Account for tabs, too.
56 Include mbswidth.h.
57 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
58 (extend_location): New function.
59 (YY_LINES): Remove.
60
61 Handle CRLF in C code rather than in Lex code.
62 (YY_INPUT): New macro.

67
68 Handle backslash-newline correctly in C code.
69 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
70 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
71 all uses changed.
72 (tag, splice): New EREs. Do not allow NUL or newline in tags.
73 Use {splice} wherever C allows backslash-newline.
74 YY_STEP after space, newline, vertical-tab.
75 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
76
77 (letter, id): Don't assume ASCII; e.g., spell out a-z.
78
79 ({int}, handle_action_dollar, handle_action_at): Check for integer
80 overflow.
81
82 (YY_STEP): Omit trailing semicolon, so that it's more like C.
83
84 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
85 as well as \000. Check for UCHAR_MAX, not 255.
86 Allow \x with an arbitrary positive number of digits, as in C.
87 Check for overflow here.
88 Allow \? and UCNs, for compatibility with C.
89
90 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
91 with quote slot used by complain_at.
92
93 * tests/input.at: Add tests for backslash-newline, m4 quotes
94 in symbols, long literals, and funny escapes in strings.
95
96 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
97 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

106
107 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
108 no longer used.
109
110 2002-11-02 Paul Eggert <eggert@twinsun.com>
111
112 * src/reader.c: Don't include quote.h; not needed.
113 (get_merge_function): Reword warning to be consistent with
114 type clash diagnostic in grammar_current_rule_check.
115
116 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
117 bug in trigraph handling.
118
119 * src/output.c (prepare_symbols): When printing token names,
120 escape "[" as "@<:@" and likewise for "]".
121
122 * src/system.h (errno): Remove declaration, as we are now
123 assuming C89 or better, and C89 guarantees errno.
124
125 2002-10-30 Paul Eggert <eggert@twinsun.com>
126
127 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
128 Check for close failures.
129 * src/files.h (xfclose): Return void, not int, since it always
130 returned zero.
131 * src/files.c (xfclose): Likewise. Report I/O error if ferror
132 indicates one.
133 * src/output.c (output_skeleton): Use xfclose rather than fclose
134 and ferror. xfclose now checks ferror.
135
136 * data/glr.c (YYLEFTMOST_STATE): Remove.
137 (yyreportTree): Use a stack-based leftmost state. This avoids
138 our continuing battles with bogus warnings about initializers.
139
140 2002-10-30 Akim Demaille <akim@epita.fr>
141
142 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
143 #if.
144
145 2002-10-24 Paul Eggert <eggert@twinsun.com>
146
147 Version 1.75a.
148
149 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
150 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
151 we use malloc. Don't assume 'A' through 'Z' are contiguous.
152 Don't assume strdup exists; POSIX says its an XSI extension.
153 Check for buffer overflow on input.
154
155 2002-10-24 Akim Demaille <akim@epita.fr>
156
157 * src/output.c (output_skeleton): Don't disable M4sugar comments
158 too soon: it results in comments being expanded.
159 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
160 first output.
161
162 2002-10-24 Akim Demaille <akim@epita.fr>
163
164 * data/yacc.c (m4_int_type): New.
165 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
166 char' as only yacc.c wants K&R portability.
167 * data/glr.c (yysigned_char): Remove.
168 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
169 Reported by Quoc Peyrot.
170
171 2002-10-23 Paul Eggert <eggert@twinsun.com>
172
173 * src/main.c (main): With --trace=time, report times even if a
174 non-fatal error occurs. Formerly, the times were reported in some
175 such cases but not in others.
176 * src/reader.c (reader): Just return if a complaint has been issued,
177 instead of exiting, so that 'main' can report times.
178
179 2002-10-22 Akim Demaille <akim@epita.fr>
180
181 * src/system.h: Include sys/types.
182 Reported by Bert Deknuydt.
183
184 2002-10-23 Paul Eggert <eggert@twinsun.com>
185
186 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
187 Suggested by Art Haas.
188
189 2002-10-22 Paul Eggert <eggert@twinsun.com>
190
191 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
192 decl; not needed any more.
193 * src/main.c (main): Use return to exit, undoing yesterday's change.
194 The last OS that we could find where this wouldn't work is
195 SunOS 3.5, and that's too old to worry about now.
196
197 * data/glr.c (struct yyltype): Define members even when not
198 doing locations. This is more consistent with yacc.c, and it
199 works around the following bug reports:
200 http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html
201 http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
202 and I hope it also fixes this bug report:
203 http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html
204
205 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
206 @acronym consistently. Standardize on "Yacc" instead of "YACC",
207 "Algol" instead of "ALGOL". Give a bit more history about BNF.
208
209 2002-10-22 Akim Demaille <akim@epita.fr>
210
211 * data/README: New.
212
213 2002-10-21 Paul Eggert <eggert@twinsun.com>
214
215 Be consistent about 'bool'; the old code used an enum in one
216 module and an int in another, and this violates the C standard.
217 * m4/stdbool.m4: New file, from coreutils 4.5.3.
218 * configure.ac (AC_HEADER_STDBOOL): Add.
219 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
220 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
221 * src/symtab.c (hash_compare_symbol_t): Likewise.
222 * src/system.h (bool, false, true): Use a definition consistent
223 with ../lib/hash.c. All uses changed.
224
225 * src/complain.c (warning_issued): Renamed from warn_message_count,
226 so that we needn't worry about integer overflow (!).
227 Now of type bool. All uses changed.
228 (complaint_issued): Renamed from complain_message_count; likewise.
229
230 * src/main.c (main): Use exit to exit with failure.
231
232 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
233 rather than 1 and 0.
234 * src/main.c (main): Likewise.
235 * src/getargs.c (getargs): Likewise.
236 * src/reader.c (reader): Likewise.
237
238 * src/getarg.c (getargs): Remove duplicate code for
239 "Try `bison --help'".
240
241 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
242 What was that "2" for?
243
244 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
245 * src/getargs.c (usage): Likewise.
246
247 * src/getargs.c (getargs): When there are too few operands, report
248 the last one. When there are too many, report the first extra
249 one. This is how diffutils does it.
250
251 2002-10-20 Paul Eggert <eggert@twinsun.com>
252
253 Remove K&R vestiges.
254 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
255 * src/complain.c (VA_START): Remove. Assume prototypes.
256 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
257 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
258 fatal): Assume prototypes.
259 * src/complain.h: Assume prototypes.
260 * src/system.h (PARAMS): Remove.
261 Include <limits.h> unconditionally, since it's guaranteeed even
262 for a freestanding C89 compiler.
263 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
264 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
265
266 2002-10-20 Akim Demaille <akim@epita.fr>
267
268 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
269 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
270 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
271 (yyresolveStates, yyresolveAction, yyresolveStack)
272 (yyprocessOneStack): Use them.
273 (yy_reduce_print): New.
274 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
275
276 2002-10-20 Akim Demaille <akim@epita.fr>
277
278 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
279 arguments and output `void'.
280 (b4_c_function): Rename as...
281 (b4_c_function_def): this.
282 (b4_c_function_decl, b4_c_ansi_function_def)
283 (b4_c_ansi_function_decl): New.
284 Change the interpretation of the arguments: before `int, foo', now
285 `int foo, foo'.
286 * data/yacc.c (yyparse): Prototype and define thanks to these.
287 Adjust b4_c_function_def uses.
288 * data/glr.c (yyparse): Likewise, but ANSI only.
289
290 2002-10-20 Akim Demaille <akim@epita.fr>
291
292 * src/output.c (prepare): Move the definition of `tokens_number',
293 `nterms_number', `undef_token_number', `user_token_number_max'
294 to...
295 (prepare_tokens): Here.
296 (prepare_tokens): Rename as...
297 (prepare_symbols): this.
298 (prepare): Move the definition of `rules_number' to...
299 (prepare_rules): here.
300 (prepare): Move the definition of `last', `final_state_number',
301 `states_number' to...
302 (prepare_states): here.
303 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
304
305 2002-10-20 Akim Demaille <akim@epita.fr>
306
307 * src/tables.h, src/tables.c, src/output.c: Comment changes.
308
309 2002-10-20 Akim Demaille <akim@epita.fr>
310
311 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
312 * data/c.m4: here.
313
314 2002-10-20 Akim Demaille <akim@epita.fr>
315
316 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
317 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
318 `pair'.
319 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
320 `name' to...
321 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
322 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
323 These.
324
325 2002-10-19 Paul Eggert <eggert@twinsun.com>
326
327 Do not create a temporary file, as that involves security and
328 cleanup headaches. Instead, use a pair of pipes.
329 Derived from a suggestion by Florian Krohm.
330 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
331 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
332 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
333 (BISON_PREREQ_SUBPIPE): Add.
334 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.

337 * po/POTFILES.in: Add lib/subpipe.c.
338 * src/output.c: Include "subpipe.h".
339 (m4_invoke): Remove decl.
340 (scan_skel): New decl.
341 (output_skeleton): Use pipe rather than temporary file for m4 input.
342 Check that m4sugar.m4 is readable, to avoid deadlock.
343 Check for pipe I/O error.
344 * src/scan-skel.l (readpipe): Remove decl.
345 (scan_skel): New function, to be used in place of m4_invoke.
346 Read from stream rather than file.
347
348 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
349 float, as this generates a warning on Solaris 8 + GCC 3.2 with
350 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
351 this generates a more-accurate value anyway.
352
353 * lib/timevar.c (timervar_accumulate): Rename locals to
354 avoid confusion with similarly-named more-global.
355 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
356
357 * src/output.c (prepare): Use xstrdup to convert char const *
358 to char *, to avoid GCC warning.
359
360 2002-10-19 Akim Demaille <akim@epita.fr>
361
362 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
363 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
364 Use them to have `calc.y' ready for %pure-parser.
365 * data/yacc.c (YYLEX): Pass a yylex return type to
366 b4_c_function_call.
367
368 2002-10-19 Akim Demaille <akim@epita.fr>
369
370 Prototype support of %lex-param and %parse-param.
371
372 * src/parse-gram.y: Add the definition of the %lex-param and
373 %parse-param tokens, plus their rules.
374 Drop the `_' version of %glr-parser.
375 Add the "," token.
376 * src/scan-gram.l (INITIAL): Scan them.
377 * src/muscle_tab.c: Comment changes.
378 (muscle_insert, muscle_find): Rename `pair' as `probe'.
379 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
380 (muscle_entry_s): The `value' member is no longer const.
381 Adjust all dependencies.
382 * src/muscle_tab.c (muscle_init): Adjust: use
383 MUSCLE_INSERT_STRING.
384 Initialize the obstack earlier.
385 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
386 (muscle_pair_list_grow): New.
387 * data/c.m4 (b4_c_function_call, b4_c_args): New.
388 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
389 * tests/calc.at: Use %locations, not --locations.
390 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
391
392 2002-10-19 Akim Demaille <akim@epita.fr>
393
394 * src/getargs.c (usage): Take status as argument and exit
395 accordingly.
396 Report the traditional `Try ... --help' message when status != 0.
397 (usage, version): Don't take a FILE * as arg, it is pointless.
398 (getargs): When there is an incorrect number of arguments, make it
399 an error, and report it GNUlically thanks to `usage ()'.
400
401 2002-10-18 Paul Eggert <eggert@twinsun.com>
402
403 * data/glr.c (yyreportParseError): Don't assume that sprintf
404 yields the length of the printed string, as this is not true
405 on SunOS 4.1.4. Reported by Peter Klein.
406
407 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
408 * tests/conflicts.at (%nonassoc and eof): Likewise.
409 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
410
411 2002-10-17 Akim Demaille <akim@epita.fr>
412
413 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
414 * src/getargs.c (trace_types, trace_args): Adjust.
415 * src/reader.c (grammar_current_rule_prec_set)
416 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
417 Standardize error messages.
418 And s/@prec/%prec/!
419 (reader): Use trace_flag to enable scanner/parser debugging,
420 instead of an adhoc scheme.
421 * src/scan-gram.l: Remove trailing debugging code.
422
423 2002-10-16 Paul Eggert <eggert@twinsun.com>
424
425 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
426 MUSCLE_TAB_H.
427
428 * NEWS: Officially drop support for building Bison with K&R C,
429 since it didn't work anyway and it's not worth worrying about.
430 * Makefile.maint (wget_files): Remove ansi2knr.c.
431 (ansi2knr.c-url_prefix): Remove.
432 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
433 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
434 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
435
436 2002-10-15 Paul Eggert <eggert@twinsun.com>
437
438 Stop using the "enum_" trick for K&R-style function definitions;
439 it confused me, and I was the author! Instead, assume that people
440 who want to use K&R C compilers (when using these modules in GCC,
441 perhaps?) will run ansi2knr.
442
443 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
444 All uses of "enum_" changed to "enum ".

456 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
457 Use function prototypes; this removes the need for declaring
458 static functions simply to provide their prototypes.

512 2002-10-14 Akim Demaille <akim@epita.fr>
513
514 Version 1.75.
515
516 2002-10-14 Akim Demaille <akim@epita.fr>
517
518 * tests/Makefile.am (maintainer-check-posix): New.
519
520 2002-10-14 Akim Demaille <akim@epita.fr>
521
522 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
523 member.
524
525 2002-10-14 Akim Demaille <akim@epita.fr>
526
527 * src/tables.c (table_ninf_remap): base -> tab.
528 Reported by Matt Rosing.
529
530 2002-10-14 Paul Eggert <eggert@twinsun.com>
531
532 * tests/action.at, tests/calc.at, tests/conflicts.at,
533 tests/cxx-type.at, tests/headers.at, tests/input.at,
534 tests/regression.at, tests/synclines.at, tests/torture.at:
535 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
536 so that the tests still work even if POSIXLY_CORRECT is set.
537 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
538
539 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
540 for portability to K&R hosts. Fix typo: signed char is guaranteed
541 only to 127, not to 128.
542 * data/glr.c (yysigned_char): New type.
543 * data/yacc.c (yysigned_char): Likewise.
544 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
545
546 2002-10-13 Paul Eggert <eggert@twinsun.com>
547
548 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
549 true due to limited range of data type" warning from GCC.
550
551 * data/c.m4 (b4_token_defines): Protect against double-inclusion
552 by wrapping enum yytokentype's definition inside #ifndef
553 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
554
555 2002-10-13 Akim Demaille <akim@epita.fr>
556
557 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
558 Un yy- yyrhs to avoid the name clash with the global YYRHS.
559
560 2002-10-13 Akim Demaille <akim@epita.fr>
561
562 * Makefile.maint: Update from Autoconf 2.54.
563 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
564
565 2002-10-13 Akim Demaille <akim@epita.fr>
566
567 * src/print.c (print_state): Separate the list of solved conflicts
568 from the other items.
569 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
570
571 2002-10-13 Akim Demaille <akim@epita.fr>
572
573 Let nondeterministic skeletons be usable with deterministic
574 tables.
575
576 With the patch, GAWK compiled by GCC without -O2 passes its test
577 suite using a GLR parser driven by LALR tables. It fails with -O2
578 because `struct stat' gives two different answers on my machine:
579 88 (definition of an auto var) and later 96 (memset on this var).
580 Hence the stack is badly corrumpted. The headers inclusion is to
581 blame: if I move the awk.h inclusion before GLR's system header
582 inclusion, the two struct stat have the same size.
583
584 * src/tables.c (pack_table): Always create conflict_table.
585 (token_actions): Always create conflict_list.
586 * data/glr.c (YYFLAG): Remove, unused.
587
588 2002-10-13 Akim Demaille <akim@epita.fr>
589
590 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
591 (O0FLAGS): New.
592 (VALGRIND, GXX): New.
593 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
594 * tests/bison.in: Run $PREBISON a pre-command.
595 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
596 (maintainer-check-g++): New.
597 * Makefile.am (maintainer-check): New.
598
599 2002-10-13 Akim Demaille <akim@epita.fr>
600
601 * data/glr.c: Formatting changes.
602 Tweak some trace messages to match yacc.c's.
603
604 2002-10-13 Akim Demaille <akim@epita.fr>
605
606 GLR parsers sometimes raise parse errors instead of performing the
607 default reduction.
608 Reported by Charles-Henry de Boysson.
609
610 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
611 check the length of the traces when %glr.
612 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
613 GLR's traces.
614 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
615 Test GLR parsers.
616 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
617 (yyltype): Remove the yy prefix from the member names.
618 (yytable): Complete its comment.
619 (yygetLRActions): Map error action number from YYTABLE from
620 YYTABLE_NINF to 0.
621 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
622 (which was a bug: it should have been YYTABEL_NINF, and yet it was
623 not satisfying as we could compare an YYACTION computed from
624 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
625 only value for error actions.
626 (yyreportParseError): In verbose parse error messages, don't issue
627 `error' in the list of expected tokens.
628 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
629 next action to perform to match glr.c's decoding.
630 (yytable): Complete its comment.
631
632 2002-10-13 Paul Eggert <eggert@twinsun.com>
633
634 Fix problem reported by Henrik Grubbstroem in
635 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
636 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
637 because the Bison parser reads the second action before reducing
638 the first one.
639 * src/scan-gram.l (rule_length): New static var.
640 Use it to keep track of the rule length in the scanner, since
641 we can't expect the parser to be in lock-step sync with the scanner.
642 (handle_action_dollar, handle_action_at): Use this var.
643 * tests/actions.at (Exotic Dollars): Test for the problem.
644
645 2002-10-12 Paul Eggert <eggert@twinsun.com>
646
647 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
648 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
649 Include <sys/time.h> when checking for clock_t and struct tms.
650 Use same include order as source.
651 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
652 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.
653
654 * lib/timevar.c: Update copyright date and clarify comments.
655 (get_time) [IN_GCC]: Keep the GCC version for reference.
656
657 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
658 GCC version as of today, then merge Bison's changes.
659 Change "GCC" to "Bison" in copyright notice. timevar.def's
660 author is Akim, so change that too.
661
662 * src/reader.c (grammar_current_rule_check):
663 Don't worry about the default action if $$ is untyped.
664 Prevents bogus warnings reported by Jim Gifford in
665 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>.
666
667 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
668 * data/glr.c, data/lalr1.cc, data/yacc.c:
669 Output token definitions before the first part of user declarations.
670 Fixes compatibility problem reported by Jim Gifford for kbd in
671 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.
672
673 2002-10-11 Paul Eggert <eggert@twinsun.com>
674
675 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
676 (yyparse): here. This undoes some of the 2002-07-25 change.
677 Compatibility problem reported by Ralf S. Engelschall with
678 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
679
680 2002-10-11 Akim Demaille <akim@epita.fr>
681
682 * tests/regression.at Characters Escapes): New.
683 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
684 characters.
685 Reported by Jan Nieuwenhuizen.
686
687 2002-10-11 Akim Demaille <akim@epita.fr>
688

690
691 2002-10-10 Paul Eggert <eggert@twinsun.com>
692
693 Portability fixes for bitsets; this also avoids several GCC
694 warnings.
695
696 * lib/abitset.c: Include <stddef.h>, for offsetof.
697 * lib/lbitset.c: Likewise.
698
699 * lib/abitset.c (abitset_bytes): Return a size that is aligned
700 properly for vectors of objects. Do not assume that adding a
701 header size to a multiple of a word size yields a value that is
702 properly aligned for the whole union.
703 * lib/bitsetv.c (bitsetv_alloc): Likewise.
704
705 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
706 unique names for structures.
707 * lib/ebitset.c (ebitset_bytes): Likewise.
708 * lib/lbitset.c (lbitset_bytes): Likewise.
709
710 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
711 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
712 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,

715 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
716 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
717 to improve the type-checking that GCC can do.
718 * lib/bitset.c (bitset_op4_cmp): Likewise.
719 * lib/bitset_stats.c (bitset_stats_count,
720 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
721 bitset_stats_copy, bitset_stats_disjoint_p,
722 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,

724 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
725 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
726 bitset_stats_and_or_cmp, bitset_stats_andn_or,
727 bitset_stats_andn_or_cmp, bitset_stats_or_and,
728 bitset_stats_or_and_cmp): Likewise.
729 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
730 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
731 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
732 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
733
734 * lib/abitset.h: Include bitset.h, not bbitset.h.
735 * lib/ebitset.h: Likewise.
736 * lib/lbitset.h: Likewise.
737
738 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
739 All instances of parameters of type enum bitset_opts are now of
740 type enum_bitset_opts, to conform to the C Standard, and similarly
741 for enum_bitset_type.
742 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
743 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
744
745 Do not use "struct bitset_struct" to mean different things in
746 different modules. Not only is this confusing, it violates
747 the C Standard, which requires that structure types in different
748 modules must be compatible if one is to be passed to the other.
749 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
750 All instances of "struct bitset_struct *" replaced with "bitset".
751 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
752 (union bitset_union, struct abitset_struct, struct ebitset_struct,
753 struct lbitset_struct, struct bitset_stats_struct): New types.
754 All uses of struct bitset_struct changed to union bitset_union,
755 etc.
756 * lib/abitset.c (struct abitset_struct, abitset,
757 struct bitset_struct): Remove.
758 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
759 struct bitset_struct): Remove.
760 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
761 bitset_struct): Remove.
762 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
763 Likewise.
764
765 Do not call a function of type T using a call that assumes the
766 function is of a different type U. Standard C requires that a
767 function must be called with a type that is compatible with its
768 definition.
769 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
770 New decls.
771 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
772 New functions.
773 * lib/ebitset.c (PFV): Remove.
774 * lib/lbitset.c (PFV): Likewise.
775 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
776 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
777 decls.
778 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
779 (ebitset_vtable): Use them.
780 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
781 lbitset_xor): New functions.
782 (lbitset_vtable): Use them.
783
784 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
785 Declare.
786
787 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
788 GCC warning.
789 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
790 Use offsetof, for simplicity.
791
792 2002-10-06 Paul Eggert <eggert@twinsun.com>
793
794 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
795 the same width as int. This reapplies a hunk of the 2002-08-12 patch
796 <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
797 which was inadvertently undone by the 2002-09-30 patch.
798 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
799 the same width as int.
800
801 2002-10-04 Paul Eggert <eggert@twinsun.com>
802
803 Version 1.50.
804
805 * configure.ac (AC_INIT), NEWS: Increment version number.
806
807 * doc/bison.texinfo: Minor spelling, grammar, and white space
808 fixes.
809 (Symbols): Mention that any negative value returned from yylex
810 signifies end-of-input. Warn about negative chars. Mention
811 the portable Standard C character set.
812
813 The GNU coding standard says CFLAGS and YFLAGS are reserved
814 for the installer to set.
815 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
816 * src/Makefile.am (AM_CFLAGS): Likewise.
817 (AM_YFLAGS): Renamed from YFLAGS.
818
819 Fix some MAX and MIN problems.
820 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
821 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
822 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
823 * src/reader.c (reader): Use it.
824
825 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
826 POSIX 1003.1-2001 has removed fgrep.
827
828 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
829
830 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
831 interpreted as signed.
832 * lib/ebitset.c (ebitset_list): Fix bug.
833
834 2002-10-01 Paul Eggert <eggert@twinsun.com>
835
836 More fixes for 64-bit hosts and large bitsets.
837
838 * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
839 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
840 Use bitset_bindex, not int or unsigned int or size_t, to count bits.

903 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,

1004
1005 * doc/bison.texinfo (Conditions): Make explicit that the GPL

1018
1019 2002-09-04 Jim Meyering <jim@meyering.net>
1020
1021 * data/yacc.c: Guard the declaration of yytoknum also with
1022 `#ifdef YYPRINT', so it is declared only when used.

1056 functions are not portable. Do not assume size_t is the
1057 same width as int.
1058 (yypstates): Do not assume that ptrdiff_t is the same width
1059 as int, and similarly for yyposn and YYINDEX.
1060
1061 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
1062
1063 * lib/Makefile.am (INCLUDES): Do not include from the intl
1064 directory, which has been removed.
1065 * src/Makefile.am (INCLUDES): Likewise.

1098 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
1099
1100 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
1101 PROTOTYPES to check for prototypes, and "defined __STDC__" to
1102 check for void *.
1103
1104 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
1105 size_t; the old version tried to do this but casted improperly.
1106 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
1107 (bitset_test): Now returns int, not unsigned long.
1108
1109 * lib/bitset_stats.c: Include "gettext.h".
1110 (_): New macro.
1111 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
1112 name locals "index", as it generates unnecessary warnings on some
1113 hosts that have an "index" function.

1115 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
1116 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

1137 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
1138 lib/timevar.c.
1139 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
1140 manual recommends.
1141 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
1142
1143 * src/complain.c (strerror_r): Remove decl; not needed.
1144 (strerror): Use same pattern as ../lib/error.c.
1145
1146 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
1147
1148 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
1149
1150 * src/main.c (main): Cast result of bindtextdomain and textdomain
1151 to void, to avoid a GCC warning when --disable-nls is in effect.
1152
1153 * src/scan-gram.l: Use strings rather than escapes when possible,
1154 to minimize the number of warnings from xgettext.
1155 (handle_action_dollar, handle_action_at): Don't use isdigit,
1156 as it mishandles negative chars and it may not work as expected
1157 outside the C locale.
1158
1159 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
1160 this is a GCC extension and is not portable to other compilers.
1161
1162 * src/system.h (alloca): Use same pattern as ../lib/error.c.
1163 Do not include <ctype.h>; no longer needed.
1164 Do not include <malloc.h>; no longer needed (and generates
1165 warnings on OpenBSD 3.0).
1166
1167 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
1168 it's not portable.
1169
1170 * tests/regression.at: Do not use 'cc -c input.c -o input';
1171 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
1172
1173 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
1174 exit status as failure, not just exit status 1. Sun C exits
1175 with status 2 sometimes.
1176
1177 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
1178 Use it for the two large tests.
1179
1180 2002-08-02 Akim Demaille <akim@epita.fr>
1181
1182 * src/conflicts.c (conflicts_output): Don't output rules never
1183 reduced here, since anyway that computation doesn't work.

1189 (grammar_rules_never_reduced_report): New.
1190 * src/tables.c (action_row): Move the computation of rules never
1191 reduced to...
1192 (token_actions): here.
1193 * src/main.c (main): Make the parser before making the report, so
1194 that rules never reduced are computed.
1195 Call grammar_rules_never_reduced_report.
1196 * src/print.c (print_results): Report rules never reduced.
1197 * tests/conflicts.at, tests/reduce.at: Adjust.
1198
1199 2002-08-01 Akim Demaille <akim@epita.fr>
1200
1201 Instead of attaching lookaheads and duplicating the rules being
1202 reduced by a state, attach the lookaheads to the reductions.
1203
1204 * src/state.h (state_t): Remove the `lookaheads',
1205 `lookaheads_rule' member.
1206 (reductions_t): Add a `lookaheads' member.
1207 Use a regular array for the `rules'.
1208 * src/state.c (reductions_new): Initialize the lookaheads member
1209 to 0.
1210 (state_rule_lookaheads_print): Adjust.
1211 * src/state.h, src/state.c (state_reductions_find): New.

1216 (state_lookaheads_count): New.
1217 (states_lookaheads_initialize): Merge into...
1218 (initialize_LA): this.
1219 (lalr_free): Adjust.
1220 * src/main.c (main): Don't free nullable and derives too early: it
1221 is used by --verbose.
1222 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
1223
1224 2002-08-01 Akim Demaille <akim@epita.fr>
1225
1226 * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
1227 `rule_number_t**'.
1228 (set_derives, free_derives): Rename as...
1229 (derives_compute, derives_free): this.
1230 Adjust all dependencies.
1231 * src/nullable.c (set_nullable, free_nullable): Rename as...
1232 (nullable_compute, nullable_free): these.
1233 (rule_list_t): Store rule_t *, not rule_number_t.
1234 * src/state.c (state_rule_lookaheads_print): Directly compare rule
1235 pointers, instead of their numbers.
1236 * src/main.c (main): Call nullable_free, and derives_free earlier,
1237 as they were lo longer used.
1238
1239 2002-08-01 Akim Demaille <akim@epita.fr>
1240
1241 * lib/timevar.c (get_time): Include children time.
1242 * src/lalr.h (LA, LArule): Don't export them: used with the
1243 state_t.
1244 * src/lalr.c (LA, LArule): Static.
1245 * src/lalr.h, src/lalr.c (lalr_free): New.
1246 * src/main.c (main): Call it.
1247 * src/tables.c (pack_vector): Check whether loc is >= to the
1248 table_size, not >.
1249 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
1250 (tables_generate): do it, since that's also it which allocates
1251 them.
1252 Don't free LA and LArule, main does.
1253
1254 2002-07-31 Akim Demaille <akim@epita.fr>
1255
1256 Separate parser tables computation and output.
1257

1289 * src/system.h: Adjust to using timevar.h.
1290 * src/getargs.h, src/getargs.c: Support trace_time for
1291 --trace=time.
1292 * src/main.c (stage): Remove.
1293 (main): Replace `stage' invocations with timevar calls.
1294 * src/output.c: Insert pertinent timevar calls.
1295

1301 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.

1339 by conflicts.
1340
1341 * src/LR0.c (save_reductions): Don't make the final state too
1342 different: save its reduction (accept) instead of having a state
1343 without any action (no shift or goto, no reduce).
1344 Note: the final state is now a ``regular'' state, i.e., the
1345 parsers now contain `reduce 0' as default reduction.

1347 final_state, they still will not reduce rule 0.

1390 2002-07-26 Akim Demaille <akim@epita.fr>
1391
1392 * src/reader.h, src/reader.c (gram_error): ... can't get
1393 yycontrol without making too strong assumptions on the parser
1394 itself.
1395 * src/output.c (prepare_tokens): Use the real 0th value of
1396 token_translations instead of `0'.
1397 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
1398 visible here.
1399 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
1400 for the time being: %locations ought to provide it to yyerror.
1401
1402 2002-07-25 Akim Demaille <akim@epita.fr>
1403
1404 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

1413 * src/nullable.c, src/output.c, src/print.c, src/reader.c
1414 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].

1416 Use rule_number_as_item_number and item_number_as_rule_number.
1417 Adjust to `derive' now containing possibly 0.
1418 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
1419 Handle the `- 1' part in rule numbers from/to item numbers.

3018 (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
3019 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
3020 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
3021 constructors or destructors.
3022
3023 (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.
3024
3025 2002-04-23 Akim Demaille <akim@epita.fr>
3026
3027 * tests/sets.at (AT_EXTRACT_SETS): Don't use 8 char long sed labels.
3028 * tests/synclines.at (AT_TEST_SYNCLINE): Be robust to GCC's
3029 location with columns.
3030 * tests/conflicts.at (%nonassoc and eof): Don't use `error.h'.
3031 All reported by Paul Eggert.
3032
3033 2002-04-22 Akim Demaille <akim@epita.fr>
3034
3035 * src/reduce.c (dump_grammar): Move to...
3036 * src/gram.h, src/gram.c (grammar_dump): here.
3037 Be sure to separate long item numbers.
3038 Don't read the members of a rule's prec if its nil.

3040 2002-04-22 Akim Demaille <akim@epita.fr>
3041
3042 * src/output.c (table_size, table_grow): New.
3043 (MAXTABLE): Remove, replace uses with table_size.

3045
3046 2002-04-22 Akim Demaille <akim@epita.fr>
3047
3048 * data/bison.simple (yyr1): Its type is that of a token number.
3049 * data/bison.c++ (r1_): Likewise.
3050 * tests/regression.at (Web2c Actions): Adjust.
3051
3052 2002-04-22 Akim Demaille <akim@epita.fr>
3053
3054 * src/reader.c (token_translations_init): 256 is now the default
3055 value for the error token, i.e., it will be assigned another
3056 number if the user assigned 256 to one of her tokens.
3057 (reader): Don't force 256 to error.
3058 * doc/bison.texinfo (Symbols): Adjust.
3059 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
3060 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
3061 etc. instead of 10, 20, 30 (which was used to `jump' over error
3062 (256) and undefined (2)).
3063
3064 2002-04-22 Akim Demaille <akim@epita.fr>
3065
3066 Propagate more token_number_t.
3067
3068 * src/gram.h (token_number_as_item_number)
3069 (item_number_as_token_number): New.
3070 * src/output.c (GENERATE_OUTPUT_TABLE): New.
3071 Use it to create output_item_number_table and
3072 output_token_number_table.
3073 * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c,
3074 * src/lex.c, src/nullable.c, src/output.c, src/print.c,
3075 * src/print_graph.c, src/reader.c, src/reduce.c, src/state.h,

3078 2002-04-22 Akim Demaille <akim@epita.fr>
3079
3080 * src/output.h, src/output.c (get_lines_number): Remove.
3081
3082 2002-04-19 Akim Demaille <akim@epita.fr>
3083
3084 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
3085 as Lex/Flex'.
3086 (Debugging): More details about enabling the debugging features.
3087 (Table of Symbols): Describe $$, $n, @$, and @n.
3088 Suggested by Tim Josling.
3089
3090 2002-04-19 Akim Demaille <akim@epita.fr>
3091
3092 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
3093
3094 2002-04-10 Akim Demaille <akim@epita.fr>
3095
3096 * src/system.h: Rely on HAVE_LIMITS_H.
3097 Suggested by Paul Eggert.
3098
3099 2002-04-09 Akim Demaille <akim@epita.fr>
3100
3101 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
3102 full stderr, and strip it according to the bison options, instead
3103 of composing the error message from different bits.
3104 This makes it easier to check for several error messages.
3105 Adjust all the invocations.
3106 Add an invocation exercising the error token.
3107 Add an invocation demonstrating a stupid error message.
3108 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
3109 Adjust the tests.
3110 Error message are for stderr, not stdout.
3111
3112 2002-04-09 Akim Demaille <akim@epita.fr>
3113
3114 * src/gram.h, src/gram.c (error_token_number): Remove, use
3115 errtoken->number.
3116 * src/reader.c (reader): Don't specify the user token number (2)
3117 for $undefined, as it uselessly prevents using it.
3118 * src/gram.h (token_number_t): Move to...
3119 * src/symtab.h: here.
3120 (state_t.number): Is a token_number_t.
3121 * src/print.c, src/reader.c: Use undeftoken->number instead of
3122 hard coded 2.
3123 (Even though this 2 is not the same as above: the number of the
3124 undeftoken remains being 2, it is its user token number which
3125 might not be 2).
3126 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
3127 `user_token_number_max'.
3128 Output `undef_token_number'.
3129 * data/bison.simple, data/bison.c++: Use them.
3130 Be sure to map invalid yylex return values to
3131 `undef_token_number'. This saves us from gratuitous SEGV.
3132
3133 * tests/conflicts.at (Solved SR Conflicts)
3134 (Unresolved SR Conflicts): Adjust.
3135 * tests/regression.at (Web2c Actions): Adjust.
3136

3140 Adding #line.
3141 Remove the duplicate `typedefs'.

3143 Use __ofile__.
3144 * data/bison.simple: Use __ofile__.
3145 * src/scan-skel.l: Handle __ofile__.

3148
3149 * src/gram.h (item_number_t): New, the type of item numbers in
3150 RITEM. Note that it must be able to code symbol numbers as
3151 positive number, and the negation of rule numbers as negative
3152 numbers.
3153 Adjust all dependencies (pretty many).
3154 * src/reduce.c (rule): Remove this `short *' pointer: use
3155 item_number_t.
3156 * src/system.h (MINSHORT, MAXSHORT): Remove.
3157 Include `limits.h'.
3158 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
3159 (shortcpy): Remove.

3161 * src/output.c (MAXTABLE): here.
3162 (prepare_rules): Use output_int_table to output rhs.

3164 * tests/torture.at (Big triangle): Move the limit from 254 to
3165 500.
3166 * tests/regression.at (Web2c Actions): Ajust.
3167
3168 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
3169 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
3170 passes, but produces negative #line number, once fixed, GCC is
3171 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
3172 C), it passes.
3173 * src/state.h (state_h): Code input lines on ints, not shorts.
3174
3175 2002-04-08 Akim Demaille <akim@epita.fr>
3176
3177 * src/reduce.c (reduce_grammar): First reduce the nonterminals,

3190 New.
3191 Use them to define yy_token_number_type/TokenNumberType.
3192 Use this type for yytranslate.

3202
3203 2002-04-07 Akim Demaille <akim@epita.fr>

3271
3272 2002-04-07 Akim Demaille <akim@epita.fr>

3293
3294 2002-04-07 Akim Demaille <akim@epita.fr>

3300
3301 2002-04-07 Akim Demaille <akim@epita.fr>

3305
3306 * src/output.c (output_token_translations): Rename as...
3307 (prepare_tokens): this.
3308 In addition to `translate', prepare the muscles `tname' and

3321

3323 newly created state.
3324 Adjust to initialize first_state and last_state if needed.

3327 new_state.
3328 * src/closure.c (closure): Now that the initial state has its
3329 items properly set, there is no need for a special case when
3330 creating `ruleset'.
3331
3332 As a result, now the rule 0, reducing to $axiom, is visible in the
3333 outputs. Adjust the test suite.
3334

3336 (Unresolved SR Conflicts): Adjust.
3337 * tests/regression.at (Web2c Report, Rule Line Numbers): Idem.

3366 (reduce_output, dump_grammar): Adjust.
3367 * src/print.c (print_grammar): It is no longer needed to check for
3368 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

3371 2002-04-07 Akim Demaille <akim@epita.fr>
3372
3373 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
3374 lacking `+ 1' to nrules, Bison reported as useless a token if it
3375 was used solely to set the precedence of the last rule...
3376
3377 2002-04-07 Akim Demaille <akim@epita.fr>
3378
3379 * data/bison.c++, data/bison.simple: Don't output the current file
3380 name in #line, to avoid useless diffs between two identical
3381 outputs under different names.
3382
3383 2002-04-07 Akim Demaille <akim@epita.fr>
3384
3385 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

3400 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
3401 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
3402 RHS, instead of being an index in RITEMS.
3403
3404 2002-04-04 Paul Eggert <eggert@twinsun.com>

3670
3671 2002-02-14 Paul Eggert <eggert@twinsun.com>
3672
3673 Remove the support for C++ namespace cleanliness; it was
3674 causing more problems than it was curing, since it didn't work
3675 properly on some nonstandard C++ compilers. This can wait
3676 for a proper C++ parser.
3677

3722 directives around tables only needed for debugging.
3723
3724 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
3725
3726 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
3727 C++ parsers.
3728 (yy::b4_name::parse): Use print_.

3769 action member.
3770 Adjust callers.
3771 (output_skeleton): Don't look for the skeleton location, let m4 do
3772 that.
3773 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
3774 file will be used.
3775 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
3776 (prepare): Given that for the time being changesyntax is not
3777 usable in M4, rename the muscles using `-' to `_'.

3779 * src/output.h (actions_output, guards_output)
3780 (token_definitions_output): Adjust prototypes.
3781 * src/scan-skel.l: Instead of scanning the skeletons, it now
3782 processes the output of m4: `__oline__' and `#output'.

3784 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
3785 to date.
3786 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
3787 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.

3808
3809 * src/bison.simple (YYSIZE_T): Do not define merely because
3810 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
3811 On some platforms, <alloca.h> does not declare YYSTD (size_t).

3813 2002-01-27 Akim Demaille <akim@epita.fr>
3814
3815 Fix `%nonassoc and eof'.
3816
3817 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
3818 which were not properly copied! Replace
3819 memcpy (res->errs, src->errs, src->nerrs);
3820 with
3821 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
3822 !!!
3823 * tests/regression.at (%nonassoc and eof): Adjust to newest
3824 Autotest: `.' is not in the PATH.
3825

3878
3879 * src/system.h: Need to define __attribute__ away for non-GCC
3880 compilers as well (i.e. the vendor C compiler).
3881 Suggested by Albert Chin-A-Young.
3882
3883 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
3884
3885 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
3886 canonical definition.
3887 * src/system.h: Use the canonical definition for PARAMS (avoids

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

4415 2001-12-27 Akim Demaille <akim@epita.fr>
4416
4417 * src/print.c, src/print_graph.c (escape): New.
4418 Use it to quote the TAGS outputs.
4419 * src/print_graph.c (print_state): Now errors are in red, and
4420 reductions in green.
4421 Prefer high to wide: output the state number on a line of its own.
4422
4423 2001-12-27 Akim Demaille <akim@epita.fr>
4424
4425 * src/state.h, src/state.c (reductions_new): New.
4426 * src/LR0.c (set_state_table): Let all the states have a
4427 `reductions', even if reduced to 0.
4428 (save_reductions): Adjust.
4429 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
4430 * src/print.c (print_reductions, print_actions): Adjust.
4431 * src/output.c (action_row): Adjust.
4432
4433 2001-12-27 Akim Demaille <akim@epita.fr>
4434
4435 * src/state.h, src/state.c (errs_new, errs_dup): New.
4436 * src/LR0.c (set_state_table): Let all the states have an errs,
4437 even if reduced to 0.

4445
4446 2001-12-27 Akim Demaille <akim@epita.fr>
4447
4448 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
4449 * src/print.c: here.
4450 (lookaheadset, shiftset): New, used as additional storage by
4451 print_reductions.
4452 (print_results): Adjust.
4453 (print_shifts, print_gotos, print_errs): New, extracted from...
4454 (print_actions): here.
4455 * src/print_graph.c (print_actions): Remove dead code.
4456
4457 2001-12-27 Akim Demaille <akim@epita.fr>
4458
4459 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
4460 `$n' and `@n'.
4461
4462 2001-12-27 Akim Demaille <akim@epita.fr>
4463
4464 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
4465 (build_relations): Adjust.
4466
4467 2001-12-27 Akim Demaille <akim@epita.fr>
4468
4469 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
4470 duplication.
4471
4472 2001-12-27 Akim Demaille <akim@epita.fr>
4473
4474 * src/reader.c (packgram): Catch nitems overflows.
4475
4476 2001-12-27 Akim Demaille <akim@epita.fr>
4477
4478 * src/files.c, src/files.h (guard_obstack): Remove.
4479 * src/output.c (output): Adjust.
4480 * src/reader.c (parse_braces): New, factoring...
4481 (copy_action, copy_guard): these two which are renamed as...
4482 (parse_action, parse_guard): these.
4483 As a voluntary consequence, using braces around guards is now
4484 mandatory.
4485
4486 2001-12-27 Akim Demaille <akim@epita.fr>
4487
4488 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
4489 * src/reader.c (symbol_list): `guard' and `guard_line' are new
4490 members.
4491 (symbol_list_new): Adjust.
4492 (copy_action): action_line is the first line, not the last.
4493 (copy_guard): Just as for actions, store the `action' only, not
4494 the switch/case/break flesh.
4495 Don't parse the user action that might follow the guard, let...
4496 (readgram): do it, i.e., now, there can be an action after a
4497 guard.
4498 In other words the guard is just explicitly optional.
4499 (packgram): Adjust.
4500 * src/output.c (guards_output): New.
4501 (output_parser): Call it when needed.
4502 (output): Also free the guard and attrs obstacks.
4503 * src/files.c, src/files.h (obstack_save): Remove.
4504 (output_files): Remove.
4505 As a result, if one needs the former `.act' file, using an
4506 appropriate skeleton which requires actions and guards is now
4507 required.
4508 * src/main.c (main): Adjust.
4509 * tests/semantic.at: New.
4510 * tests/regression.at: Use `input.y' as input file name.
4511 Avoid 8+3 problems by requiring input.c when the test needs the
4512 parser.
4513
4514 2001-12-27 Akim Demaille <akim@epita.fr>
4515
4516 * src/reader.c (symbol_list_new): Be sure to initialize all the
4517 fields.
4518
4519 2001-12-27 Akim Demaille <akim@epita.fr>
4520
4521 All the hacks using a final pseudo state are now useless.
4522
4523 * src/LR0.c (set_state_table): state_table holds exactly nstates.
4524 * src/lalr.c (nLA): New.
4525 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
4526 instead of lookaheadsp from the pseudo state (nstate + 1).
4527
4528 2001-12-27 Akim Demaille <akim@epita.fr>
4529
4530 * src/output.c (action_row, token_actions): Use a state_t instead
4531 of a integer, and nlookaheads instead of the following state's
4532 lookaheadsp.
4533
4534 2001-12-27 Akim Demaille <akim@epita.fr>
4535
4536 * src/conflicts.c (log_resolution, flush_shift)
4537 (resolve_sr_conflict, set_conflicts, solve_conflicts)
4538 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
4539 (conflicts_print, print_reductions): Use a state_t instead of an
4540 integer when referring to a state.
4541 As much as possible, depend upon nlookaheads, instead of the
4542 `lookaheadsp' member of the following state (since lookaheads of
4543 successive states are successive, the difference between state n + 1
4544 and n served as the number of lookaheads for state n).
4545 * src/lalr.c (add_lookback_edge): Likewise.
4546 * src/print.c (print_core, print_actions, print_state)
4547 (print_results): Likewise.
4548 * src/print_graph.c (print_core, print_actions, print_state)

4554 * src/bison.hairy: Formatting/comment changes.
4555 ANSIfy.
4556 Remove `register' indications.
4557 Add plenty of `static'.
4558
4559 2001-12-27 Akim Demaille <akim@epita.fr>
4560
4561 * src/output.c (prepare): Drop the muscle `ntbase' which
4562 duplicates ntokens.
4563 * src/bison.simple: Formatting/comment changes.
4564 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
4565 is an undocumented synonym.
4566
4567 2001-12-22 Akim Demaille <akim@epita.fr>
4568
4569 * src/output.c (output_table_data): Change the prototype to use
4570 `int' for array ranges: some invocations do pass an int, not a
4571 short.
4572 Reported by Wayne Green.
4573
4574 2001-12-22 Akim Demaille <akim@epita.fr>
4575
4576 Some actions of web2c.y are improperly triggered.
4577 Reported by Mike Castle.
4578
4579 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
4580 * tests/regression.at (Web2c): Rename as...
4581 (Web2c Report): this.
4582 (Web2c Actions): New.
4583
4584 2001-12-22 Akim Demaille <akim@epita.fr>
4585
4586 Reductions in web2c.y are improperly reported.

4590 * tests/regression.at (Web2c): New.
4591
4592 2001-12-18 Akim Demaille <akim@epita.fr>
4593
4594 Some host fail on `assert (!"foo")', which expands to
4595 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
4596 Reported by Nelson Beebee.
4597
4598 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
4599 `#define it_succeeded 0' and `assert (it_succeeded)'.
4600
4601 2001-12-17 Marc Autret <autret_m@epita.fr>
4602
4603 * src/bison.simple: Don't hard code the skeleton line and filename.
4604 * src/output.c (output_parser): Rename 'line' as 'output_line'.
4605 New line counter 'skeleton_line' (skeleton-line muscle).
4606
4607 2001-12-17 Paul Eggert <eggert@twinsun.com>
4608
4609 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
4610 YYDEBUG must be defined to a nonzero value.
4611
4612 * src/bison.simple (yytname): Do not assume that the user defines
4613 YYDEBUG to a properly parenthesized expression.
4614
4615 2001-12-17 Akim Demaille <akim@epita.fr>
4616
4617 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
4618 nlookaheads is a new member.
4619 Adjust all users.
4620 * src/lalr.h (nlookaheads): Remove this orphan declaration.
4621 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
4622 state.
4623
4624 2001-12-17 Akim Demaille <akim@epita.fr>
4625
4626 * src/files.h, src/files.c (open_files, close_files): Remove.
4627 * src/main.c (main): Don't open/close files, nor invoke lex_free,
4628 let...

4642
4643 * src/output.c (output_obstack): Be static and rename as...
4644 (format_obstack): this, to avoid any confusion with files.c's
4645 output_obstack.
4646 * src/reader.h (muscle_obstack): Move to...
4647 * src/output.h: here, since it's defined in output.c.
4648
4649 2001-12-17 Akim Demaille <akim@epita.fr>
4650
4651 * src/output.c (action_row, save_column, default_goto)
4652 (sort_actions, matching_state, pack_vector): Better variable
4653 locality.
4654
4655 2001-12-17 Akim Demaille <akim@epita.fr>
4656
4657 * src/output.c: Various formatting changes.
4658
4659 2001-12-17 Akim Demaille <akim@epita.fr>
4660

4666
4667 2001-12-16 Marc Autret <autret_m@epita.fr>
4668
4669 * src/output.c (actions_output): Fix. When we use %no-lines,
4670 there is one less line per action.
4671
4672 2001-12-16 Marc Autret <autret_m@epita.fr>
4673
4674 * src/bison.simple: Remove a useless #line directive.
4675 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4676 * src/output.c (get_lines_number): New.
4677 (output_parser): Adjust, now takes care about the lines of a
4678 output muscles.
4679 Fix line numbering.
4680 (actions_output): Computes the number of lines taken by actions.
4681 (output_master_parser): Insert new skeleton which is the name of
4682 the output parser file name.
4683
4684 2001-12-15 Marc Autret <autret_m@epita.fr>

4691
4692 2001-12-15 Akim Demaille <akim@epita.fr>
4693
4694 Make `make distcheck' work.
4695
4696 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4697 system.h which uses libgettext.h.
4698
4699 2001-12-15 Akim Demaille <akim@epita.fr>
4700
4701 * src/nullable.c (set_nullable): Useless rules must be skipped,
4702 otherwise, since we range over their symbols, we might look at a
4703 nonterminal which no longer ``exists'', i.e., it is not counted in
4704 `nvars', hence we overflow our arrays.
4705
4706 2001-12-15 Akim Demaille <akim@epita.fr>
4707
4708 The header can also be produced directly, without any obstack!
4709 Yahoo!
4710
4711 * src/files.c, src/files.h (defines_obstack): Remove.
4712 (compute_header_macro): Global.
4713 (defines_obstack_save): Remove.
4714 * src/reader.c (parse_union_decl): No longer output to
4715 defines_obstack: its content can be found in the `stype' muscle
4716 anyway.
4717 (output_token_translations): Merge into...
4718 (symbols_output): this.
4719 Rename as...
4720 (symbols_save): this.
4721 (reader): Adjust.
4722 * src/output.c (header_output): New.
4723 (output): Call it.
4724
4725 2001-12-15 Akim Demaille <akim@epita.fr>
4726
4727 * src/reader.c (parse_union_decl): Instead of handling two obstack
4728 simultaneously, use one to define the `stype' muscle, and use the
4729 value of the latter to fill defines_obstack.
4730 (copy_comment): Remove.
4731 (copy_comment2): Work for a single obstack.
4732 Rename as...
4733 (copy_comment): this.
4734
4735 2001-12-15 Akim Demaille <akim@epita.fr>
4736
4737 * src/lex.c, src/lex.h (xgetc): No longer static.
4738 * src/reader.c (parse_union_decl): Revamp.
4739
4740 2001-12-15 Akim Demaille <akim@epita.fr>
4741
4742 Still making progress in separating Bison into (i) input, (ii)
4743 process, (iii) output: now we can directly output the parser file
4744 without using table_obstack at all.
4745
4746 * src/files.c, src/files.h (table_obstack): Bye bye.
4747 (parser_file_name): New.
4748 * src/files.c (compute_output_file_names): Compute it.
4749 * src/output.c (actions_output, output_parser)
4750 (output_master_parser): To a file instead of an obstack.
4751
4752 2001-12-15 Akim Demaille <akim@epita.fr>
4753
4754 Attach actions to rules, instead of pre-outputting them to
4755 actions_obstack.
4756
4757 * src/gram.h (rule_t): action and action_line are new members.
4758 * src/reader.c (symbol_list): Likewise.
4759 (copy_action): Save the actions within the rule.
4760 (packgram): Save them in rule_table.
4761 * src/output.c (actions_output): New.
4762 (output_parser): Use it on `%%actions'.
4763 (output_rule_data): Don't free rule_table.
4764 (output): Do it.
4765 (prepare): Don't save the `action' muscle.
4766 * src/bison.simple: s/%%action/%%actions/.
4767
4768 2001-12-15 Akim Demaille <akim@epita.fr>
4769
4770 * src/reader.c (copy_action): When --yacc, don't append a `;'
4771 to the user action: let it fail if lacking.
4772 Suggested by Arnold Robbins and Tom Tromey.
4773
4774 2001-12-14 Akim Demaille <akim@epita.fr>
4775
4776 * src/lex.c (literalchar): Simply return the char you decoded, non
4777 longer mess around with obstacks and int pointers.
4778 Adjust all callers.
4779
4780 2001-12-14 Akim Demaille <akim@epita.fr>
4781
4782 * src/lex.c (literalchar): Don't escape the special characters,
4783 just decode them, and keep them as char (before, eol was output as
4784 the 2 char string `\n' etc.).
4785 * src/output.c (output_rule_data): Use quotearg to output the
4786 token strings.
4787
4788 2001-12-13 Paul Eggert <eggert@twinsun.com>
4789
4790 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4791 Do not infringe on the global user namespace when using C++.
4792 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4793 All uses of `fprintf' and `stderr' changed.
4794
4795 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4796
4797 2001-12-13 Akim Demaille <akim@epita.fr>
4798
4799 The computation of nullable is broken: it doesn't handle empty
4800 RHS's properly.
4801
4802 * tests/torture.at (GNU AWK Grammar): New.
4803 * tests/sets.at (Nullable): New.
4804 * src/nullable.c (set_nullable): Instead of blindly looping over
4805 `ritems', loop over the rules, and then over their rhs's.
4806
4807 Work around Autotest bugs.
4808
4809 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4810 frame, because Autotest understand lines starting with a `+' as
4811 traces from the shell. Then, they are not processed properly.
4812 Admittedly an Autotest bug, but we don't have time to wait for
4813 Autotest to catch up.
4814 * tests/regression.at (Broken Closure): Adjust to the new table
4815 frames.
4816 Move to...
4817 * tests/sets.at: here.
4818
4819 2001-12-13 Akim Demaille <akim@epita.fr>
4820
4821 * src/closure.c (closure): Use nrules instead of playing tricks
4822 with BITS_PER_WORD.
4823
4824 2001-12-13 Akim Demaille <akim@epita.fr>
4825
4826 * src/print.c (print_actions): Output the handling of `$' as the
4827 traces do: shifting the token EOF. Before EOF was treated as a
4828 nonterminal.
4829 * tests/regression.at: Adjust some tests.
4830 * src/print_graph.c (print_core): Complete the set of items via
4831 closure. The next-to-final and final states are still unsatisfying,
4832 but that's to be addressed elsewhere.
4833 No longer output the rule numbers, but do output the state number.
4834 A single loop for the shifts + gotos is enough, but picked a
4835 distinct color for each.
4836 (print_graph): Initialize and finalize closure.
4837
4838 2001-12-13 Akim Demaille <akim@epita.fr>
4839
4840 * src/reader.c (readgram): Remove dead code, an strip useless
4841 braces.
4842 (get_type): Remove, unused.
4843
4844 2001-12-12 Akim Demaille <akim@epita.fr>
4845
4846 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4847 on that of lib/error.c.
4848
4849 2001-12-12 Akim Demaille <akim@epita.fr>
4850
4851 Some hosts don't like `/' in includes.
4852
4853 * src/system.h: Include libgettext.h without qualifying the path.
4854 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4855 $(top_srcdir).
4856
4857 2001-12-11 Marc Autret <autret_m@epita.fr>
4858
4859 * src/output.c (output_parser): Remove useless muscle.
4860
4861 2001-12-11 Marc Autret <autret_m@epita.fr>
4862
4863 * src/bison.simple: Remove #line just before %%epilogue. It
4864 is now handled in ...
4865 * src/reader.c (read_additionnal_code): Add the output of a
4866 #line for the epilogue.
4867
4868 2001-12-10 Marc Autret <autret_m@epita.fr>
4869
4870 * src/reader.c (copy_definition): Re-use CPP-outed code which
4871 replace precedent remove.
4872 * src/bison.simple: Remove #line before %%prologue because
4873 %%input-line is wrong at this time.
4874
4875 2001-12-10 Marc Autret <autret_m@epita.fr>
4876
4877 * src/reader.c (symbols_output): Clean up.
4878 * src/output.c (output_gram, output): Clean up.
4879
4880 2001-12-10 Akim Demaille <akim@epita.fr>
4881
4882 * src/lalr.c (initialize_lookaheads): New. Extracted from...
4883 * src/LR0.c (set_state_table): here.
4884 * src/lalr.c (lalr): Call it.
4885
4886 2001-12-10 Akim Demaille <akim@epita.fr>
4887
4888 * src/state.h (shifts): Remove the `number' member: shifts are
4889 attached to state, hence no longer need to be labelled with a
4890 state number.
4891
4892 2001-12-10 Akim Demaille <akim@epita.fr>
4893
4894 Now that states have a complete set of members, the linked list of
4895 shifts is useless: just fill directly the state's shifts member.
4896
4897 * src/state.h (shifts): Remove the `next' member.
4898 * src/LR0.c (first_state, last_state): Remove.
4899 Adjust the callers.
4900 (augment_automaton): Don't look for the shifts that must be added
4901 a shift on EOF: it is those of the state we looked for! But now,
4902 since shifts are attached, it is no longer needed to looking
4903 merely by its id: its number.
4904
4905 2001-12-10 Akim Demaille <akim@epita.fr>
4906
4907 * src/LR0.c (augment_automaton): Better variable locality.
4908 Remove an impossible branch: if there is a state corresponding to
4909 the start symbol being shifted, then there is shift for the start
4910 symbol from the initial state.
4911
4912 2001-12-10 Akim Demaille <akim@epita.fr>
4913
4914 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4915 only when appropriate: when insert_start_shifting_state' is not
4916 invoked.
4917 * tests/regression.at (Rule Line Numbers): Adjust.
4918
4919 2001-12-10 Akim Demaille <akim@epita.fr>
4920
4921 * src/LR0.c (augment_automaton): Now that all states have shifts,
4922 merge the two cases addition shifts to the initial state.
4923
4924 2001-12-10 Akim Demaille <akim@epita.fr>
4925
4926 * src/lalr.c (set_state_table): Move to...
4927 * src/LR0.c: here.
4928 * src/lalr.c (lalr): Don't call it...
4929 * src/LR0.c (generate_states): do it.
4930 * src/LR0.h (first_state): Remove, only the table is used.
4931
4932 2001-12-10 Akim Demaille <akim@epita.fr>
4933
4934 * src/LR0.h (first_shift, first_reduction): Remove.
4935 * src/lalr.c: Don't use first_shift: find shifts through the
4936 states.
4937
4938 2001-12-10 Akim Demaille <akim@epita.fr>
4939
4940 * src/LR0.c: Attach shifts to states as soon as they are
4941 computed.
4942 * src/lalr.c (set_state_table): Instead of assigning shifts to
4943 state, just assert that the mapping was properly done.
4944
4945 2001-12-10 Akim Demaille <akim@epita.fr>
4946
4947 * src/LR0.c (insert_start_shift): Rename as...
4948 (insert_start_shifting_state): this.
4949 (insert_eof_shifting_state, insert_accepting_state): New.
4950 (augment_automaton): Adjust.
4951 Better locality of the variables.
4952 When looking if the start_symbol is shifted from the initial
4953 state, using `while (... symbol != start_symbol ...)' sounds
4954 better than `while (... symbol < start_symbol ...)': If fail
4955 to see how the order between symbols could be relevant!
4956
4957 2001-12-10 Akim Demaille <akim@epita.fr>
4958
4959 * src/getargs.h: Don't declare `spec_name_prefix' and
4960 `spec_file_prefix', declared by src/files.h.
4961 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4962 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4963 * src/output.c (prepare): Adjust.
4964 * src/reader.c (symbols_output): Likewise.
4965 * src/vmsgetargs.c: Vaguely adjust, but who cares?
4966
4967 2001-12-10 Akim Demaille <akim@epita.fr>
4968
4969 * src/muscle_tab.c (muscle_init): NULL is a better default than
4970 `"0"'.
4971
4972 2001-12-10 Akim Demaille <akim@epita.fr>
4973
4974 * src/reader.c (reader): Calling symbols_output once is enough.
4975
4976 2001-12-10 Akim Demaille <akim@epita.fr>
4977
4978 Now that states have a complete set of members, the linked list of
4979 reductions is useless: just fill directly the state's reductions
4980 member.
4981
4982 * src/state.h (struct reductions): Remove member `number' and
4983 `next'.
4984 * src/LR0.c (first_reduction, last_reduction): Remove.
4985 (save_reductions): Don't link the new reductions, store them in
4986 this_state.
4987 * src/lalr.c (set_state_table): No need to attach reductions to
4988 states, it's already done.
4989 * src/output.c (output_actions): No longer free the shifts, then
4990 the reductions, then the states: free all the states and their
4991 members.
4992
4993 2001-12-10 Akim Demaille <akim@epita.fr>
4994
4995 * src/options.c (OPTN, DRTV, BOTH): New.
4996 (option_table): Use them.
4997
4998 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4999 the job of system.h.
5000 * src/options.c: Don't include stdio.h and xalloc.h for the same
5001 reasons.
5002
5003 2001-12-10 Akim Demaille <akim@epita.fr>
5004
5005 * src/output.c (output, prepare): Make sure the values of the
5006 muscles `action' and `prologue' are 0-terminated.
5007
5008 2001-12-10 Akim Demaille <akim@epita.fr>
5009
5010 Clean up GCC warnings.
5011
5012 * src/reader.c (copy_action): `buf' is not used.
5013 (parse_skel_decl): Be static.
5014 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
5015 * src/options.h (create_long_option_table): Have a real prototype.
5016 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
5017 (hash_delete_at): Return const void *.
5018 Adjust casts to preserve the const.
5019
5020 2001-12-10 Akim Demaille <akim@epita.fr>
5021
5022 * configure.in: Require 2.52g.
5023 M4 is not needed, but AUTOM4TE is.
5024 * m4/m4.m4: Remove.
5025 * tests/Makefile.am: Adjust.
5026
5027 2001-12-10 Akim Demaille <akim@epita.fr>
5028
5029 One structure for states is enough, even though theoretically
5030 there are LR(0) states and LALR(1) states.
5031
5032 * src/lalr.h (state_t): Remove.
5033 (state_table): Be state_t **, not state_t *.
5034 * src/state.h (core, CORE_ALLOC): Rename as...
5035 (state_t, STATE_ALLOC): this.
5036 Add the LALR(1) members: shifts, reductions, errs.
5037 * src/LR0.c (state_table): Rename as...
5038 (state_hash): this, to avoid name clashes with the global
5039 `state_table'.
5040 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
5041 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
5042
5043 2001-12-10 Akim Demaille <akim@epita.fr>
5044
5045 Bison dumps core on bash.y.
5046 Reported by Pascal Bart.
5047
5048 * src/warshall.c (bitmatrix_print): New.
5049 (TC): Use it.
5050 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
5051 j must be the outer loop.
5052 * tests/regression.at (Broken Closure): New.
5053
5054 2001-12-05 Akim Demaille <akim@epita.fr>
5055
5056 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
5057 its argument.
5058 Reported by Peter Hámorský.
5059
5060 2001-12-05 Akim Demaille <akim@epita.fr>
5061
5062 * src/conflicts.c (err_table): Remove.
5063 (resolve_sr_conflict): Adjust.
5064 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
5065 Rename as...
5066 (state_t.reductions, state_t.shifts): this.
5067
5068 2001-12-05 Akim Demaille <akim@epita.fr>
5069
5070 * src/reduce.c (reduce_grammar_tables): No longer disable the
5071 removal of useless rules via CPP but via `if (0)', so that the
5072 compiler still check the code is valid.
5073 For instance, it should have noticed `rline' no longer exists: use
5074 the `line' member of rule_t.
5075 * src/gram.c (dummy, rline): Remove, unused.
5076
5077 2001-12-05 Akim Demaille <akim@epita.fr>
5078
5079 * src/output.c (pack_vector): Use assert, not berror.
5080 * src/main.c (berror): Remove, unused.
5081
5082 2001-12-05 Akim Demaille <akim@epita.fr>
5083
5084 New experimental feature: if --verbose --trace output all the
5085 items of a state, not only its kernel.
5086
5087 * src/print.c (print_core): If `trace_flag', then invoke closure
5088 before outputting the items of the state (print_core is no longer
5089 a correct name them).
5090 (print_results): Invoke new_closure/free_closure if needed.
5091
5092 2001-12-05 Akim Demaille <akim@epita.fr>
5093
5094 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
5095 * src/closure.c, src/closure.h (itemsetsize): Rename as...
5096 (nitemset): for consistency with the rest of the project.
5097
5098 2001-12-05 Akim Demaille <akim@epita.fr>
5099
5100 * src/closure.c (print_closure): Improve.
5101 (closure): Use it for printing input and output.
5102
5103 2001-12-05 Akim Demaille <akim@epita.fr>
5104
5105 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
5106 indexed by nonterminals.
5107
5108 2001-12-05 Akim Demaille <akim@epita.fr>
5109
5110 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
5111 what it was!).
5112 * src/warshall.h: Remove accidental duplication of the content.
5113
5114 2001-12-05 Akim Demaille <akim@epita.fr>
5115
5116 * src/closure.c (set_fderives): De-obfuscate.
5117
5118 2001-12-05 Akim Demaille <akim@epita.fr>
5119
5120 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
5121
5122 2001-12-05 Akim Demaille <akim@epita.fr>
5123
5124 * src/closure.c (set_firsts): De-obfuscate.
5125
5126 2001-12-05 Akim Demaille <akim@epita.fr>
5127
5128 * src/output.c (action_row): De-obfuscate
5129 using the good o' techniques: arrays not pointers, variable
5130 locality, BITISSET, RESETBIT etc.
5131
5132 2001-12-05 Akim Demaille <akim@epita.fr>
5133
5134 Pessimize the code to simplify it: from now on, all the states
5135 have a valid SHIFTS, which NSHIFTS is possibly 0.
5136
5137 * src/LR0.c (shifts_new): Be global and move to..
5138 * src/state.c, src/state.h: here.
5139 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
5140 * src/print_graph: Adjust.
5141
5142 2001-12-05 Akim Demaille <akim@epita.fr>
5143
5144 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
5145 * src/conflicts.c: Use it.
5146 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
5147 incorrectly ``simplified''.
5148
5149 2001-12-05 Akim Demaille <akim@epita.fr>
5150
5151 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
5152 using the good o' techniques: arrays not pointers, variable
5153 locality, BITISSET, RESETBIT etc.
5154
5155 2001-12-05 Akim Demaille <akim@epita.fr>
5156
5157 * src/state.h (SHIFT_SYMBOL): New.
5158 * src/conflicts.c: Use it to deobfuscate.
5159
5160 2001-12-05 Akim Demaille <akim@epita.fr>
5161
5162 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
5163 (print_reductions): De-obfuscate using the good o' techniques:
5164 arrays not pointers, variable locality, BITISSET.
5165
5166 2001-12-05 Akim Demaille <akim@epita.fr>
5167
5168 * src/conflicts.c (print_reductions): Arrays, not pointers.
5169 Use BITISSET.
5170
5171 2001-12-05 Akim Demaille <akim@epita.fr>
5172
5173 * src/conflicts.c (print_reductions): Pessimize, but clarify.
5174
5175 2001-12-05 Akim Demaille <akim@epita.fr>
5176
5177 * src/conflicts.c (print_reductions): Improve variable locality.
5178
5179 2001-12-05 Akim Demaille <akim@epita.fr>
5180
5181 * src/conflicts.c (print_reductions): Pessimize, but clarify.
5182
5183 2001-12-05 Akim Demaille <akim@epita.fr>
5184
5185 * src/conflicts.c (print_reductions): Improve variable locality.
5186
5187 2001-12-05 Akim Demaille <akim@epita.fr>
5188
5189 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
5190 * src/lalr.c: Use them.
5191
5192 2001-12-05 Akim Demaille <akim@epita.fr>
5193
5194 * src/LR0.c (augment_automaton): Formatting changes.
5195 Better variable locality.
5196
5197 2001-12-05 Akim Demaille <akim@epita.fr>
5198
5199 * src/lalr.c (matrix_print): New.
5200 (transpose): Use it.
5201 Use arrays instead of pointers.
5202
5203 2001-12-05 Akim Demaille <akim@epita.fr>
5204
5205 * src/lalr.c (maxrhs): Move to...
5206 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
5207 * src/lalr.c (build_relations): Adjust.
5208
5209 2001-12-05 Akim Demaille <akim@epita.fr>
5210
5211 * src/lalr.c (transpose): Free the memory allocated to the
5212 argument, as it is replaced by the results by the unique caller.
5213 (build_relations): Merely invoke transpose: it handles the memory
5214 deallocation.
5215 Improve variable locality.
5216 Avoid variables used as mere abbreviations.
5217 (compute_lookaheads): Use arrays instead of pointers.
5218
5219 2001-12-05 Akim Demaille <akim@epita.fr>
5220
5221 * src/lalr.c (initialize_F): Improve variable locality.
5222 Avoid variables used as mere abbreviations.
5223
5224 2001-12-05 Akim Demaille <akim@epita.fr>
5225
5226 * src/derives.c (print_derives): Display the ruleno.
5227 * src/lalr.c (initialize_F, transpose): Better variable locality
5228 to improve readability.
5229 Avoid variables used as mere abbreviations.
5230
5231 2001-12-05 Akim Demaille <akim@epita.fr>
5232
5233 * src/lalr.c (traverse): Use arrays instead of pointers.
5234
5235 2001-12-05 Akim Demaille <akim@epita.fr>
5236
5237 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
5238 the handling of squeue.
5239 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5240
5241 2001-12-05 Akim Demaille <akim@epita.fr>
5242
5243 Because useless nonterminals are now kept alive (instead of being
5244 `destroyed'), we now sometimes examine them, and store information
5245 related to them. Hence we need to know their number, and adjust
5246 memory allocations.
5247
5248 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
5249 static.
5250 * src/LR0.c (allocate_itemsets): The memory allocated to
5251 `symbol_count' was used for two different purpose: once to count
5252 the number of occurrences of each symbol, and later reassigned to
5253 `shift_symbol', containing the symbol that can be shifted from a
5254 given state.
5255 Deobfuscate, i.e., allocate, use and free `symbol_count' here
5256 only, and...
5257 (new_itemsets): Allocate `shift_symbol' here.
5258 (allocate_itemsets): symbol_count includes useless nonterminals.
5259 Make room for them.
5260 (free_storage): Use `free', not `XFREE', for pointers that cannot
5261 be null.
5262
5263 2001-12-05 Akim Demaille <akim@epita.fr>
5264
5265 * src/nullable.c (set_nullable): Deobfuscate the handling of
5266 ritem.
5267 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5268
5269 2001-12-05 Akim Demaille <akim@epita.fr>
5270
5271 * src/gram.c, src/gram.h (ritem_print): New.
5272 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
5273 (This useless function was defined only to work around VMS linkers

5276 ritem.
5277

5281 to be the same as the stack names.
5282 (yyparse): yyptr is now union yyalloc *, not char *.
5283 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
5284 and may generate better code on some machines.
5285 (yystpcpy): Use prototype if __STDC__ is defined, not just
5286 if __cplusplus is defined.
5287
5288 2001-11-30 Akim Demaille <akim@epita.fr>
5289
5290 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
5291 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
5292 Gettext doesn't compile cleanly, and dies with -Werror.
5293 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
5294 Include WARNING_CFLAGS here.
5295 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
5296 before being defined.
5297

5303 (SIZE_MAX, UINT_MAX): New macros.
5304 (quotearg_n_options): Abort if N is negative.
5305 Avoid overflow check on hosts where size_t is 64 bits and int
5306 is 32 bits, as overflow is impossible there.
5307 Fix off-by-one typo that caused unnecessary reallocation.
5308
5309 2001-11-29 Paul Eggert <eggert@twinsun.com>

5319 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
5320
5321 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
5322 on user names when possible.
5323
5324 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
5325 Simplify test for whather <alloca.h> exists.

5328
5329 (<stdio.h>): Include if YYDEBUG.
5330
5331 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
5332 ! defined (yyoverflow) && ! defined (yymemcpy).
5333
5334 (yymemcpy, yyparse): Rename local variables as needed so that
5335 they all begin with 'yy'.
5336
5337 (yystrlen, yystpcpy): New functions.
5338
5339 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
5340 All uses changed.
5341
5342 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
5343 instead of relying on string.h functions. Use YYSTACK_ALLOC
5344 and YYSTACK_FREE instead of malloc and free.
5345

5357
5358 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
5359 if body instead of `;' to pacify GCC's warnings.
5360
5361 2001-11-30 Akim Demaille <akim@epita.fr>
5362
5363 Instead of mapping the LHS of unused rules to -1, keep the LHS
5364 valid, but flag the rules as invalid.
5365
5366 * src/gram.h (rule_t): `useful' is a new member.
5367 * src/print.c (print_grammar): Adjust.
5368 * src/derives.c (set_derives): Likewise.

5381

5383 useless nonterminals, move them at the end of the symbol arrays.
5384 (reduce_output): Adjust.
5385 * tests/reduce.at (Useless Nonterminals): Adjust.
5386
5387 2001-11-30 Akim Demaille <akim@epita.fr>

5398 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
5399 New macros.
5400 (union yyalloc): New type.
5401 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
5402 an arbitrary restriction on hosts where size_t is wider than int.
5403
5404 (yyparse): Don't dump core if alloca or malloc fails; instead, report
5405 a parser stack overflow. Allocate just one block of memory for all
5406 three stacks, instead of allocating three blocks; this typically is
5407 faster and reduces fragmentation.
5408
5409 Do not limit the number of items in the stack to a value that fits
5410 in 'int', as this is an arbitrary limit on hosts with 64-bit
5411 size_t and 32-bit int.
5412

5472

5743 (print_actions): Don't output the actions as part of the nodes,

5837
5838 * tests/calc.at, tests/output.at, tests/regression.at,
5839 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
5840 now the tests are run in private dirs, therefore AC_CLEANUP and

5843 use abs. path to find config.h.
5844 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

5862
5863 * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):

5867 * src/lex.c (parse_percent_token): Replace equal_offset with
5868 arg_offset.
5869 arg is const.

7223 New, from fileutils 4.0.37.

7226 issues in Bison, it would mean way too much duplicate effort to
7227 import in Bison features implemented in 2.49c since 2.13.
7228 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

7241 (init_lex): Initialize it. No longer call...
7242 (grow_token_buffer): this. Remove it.

7244
7245 2001-01-19 Akim Demaille <akim@epita.fr>
7246
7247 * src/lex.h: Rename all the tokens:
7248 s/\bENDFILE\b/tok_eof/g;
7249 s/\bIDENTIFIER\b/tok_identifier/g;

7262
7263 * src/lex.c (percent_table): Also accept `%yacc',
7264 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
7265 `%debug'.
7266 Handle the actions for `%semantic_parser' and `%pure_parser' here,
7267 instead of returning a token.
7268 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
7269 * src/reader.c (read_declarations): Adjust.
7270 * src/files.c (open_files): Don't call `compute_base_names', don't
7271 compute `attrsfile' since they depend upon data which might be
7272 *in* the input file now.
7273 (output_files): Do it here.
7274 * src/output.c (output_headers): Document the fact that this patch
7275 introduces a guaranteed SEGV for semantic parsers.
7276 * doc/bison.texinfo: Document them.
7277 * tests/suite.at: Exercise these %options.

7295
7296 2000-12-20 Akim Demaille <akim@epita.fr>
7297
7298 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
7299 (copy_dollar): Now that everything uses obstacks, get rid of the
7300 FILE * parameters.
7301
7302 2000-12-20 Akim Demaille <akim@epita.fr>
7303
7304 * src/files.c (open_files): Actually the `.output' file is based
7305 on the short_base_name, not base_name.
7306 * tests/suite.at (Checking output file names): Adjust.
7307
7308 2000-12-20 Akim Demaille <akim@epita.fr>

7332
7333 * src/files.c (strsuffix): New.
7334 (stringappend): Be just like strcat but allocate.
7335 (base_names): Eve out from open_files.
7336 Try to simplify the rather hairy computation of base_name and
7337 short_base_name.
7338 (open_files): Use it.
7339 * tests/suite.at (Checking output file names): New test.
7340

7376
7377 2000-12-19 Akim Demaille <akim@epita.fr>
7378
7379 * src/files.c (open_files): Yipee! We no longer need all the code

7382 2000-12-19 Akim Demaille <akim@epita.fr>
7383
7384 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

7412 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
7413 prevents type checking.
7414 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
7415 cast the value to (void *): assigning a `foo *' to a `void *'
7416 variable is valid.
7417 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
7418 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

7434
7435 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
7436 macros.

7463 argument `data' for consistency with the prototypes.
7464 Qualify it `const'.
7465 (obstack_copy, obstack_copy0): Rename the second argument as
7466 `address' for consistency. Qualify it `const'.
7467 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
7468 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
7469 `const' their input argument (`data' or `address').

7496 (output_files): this.
7497 Use `obstack_save'.

7564
7565 * src/lex.c (read_typename): New function.
7566 (lex): Use it.
7567 * src/reader.c (copy_dollar): Likewise.
7568
7569 2000-10-16 Akim Demaille <akim@epita.fr>
7570
7571 * src/reader.c (copy_comment2): Expect the input stream to be on
7572 the `/' which is suspected to open a comment, instead of being
7573 called after `//' or `/*' was read.
7574 (copy_comment, copy_definition, parse_union_decl, copy_action)
7575 (copy_guard): Adjust.
7576
7577 2000-10-16 Akim Demaille <akim@epita.fr>
7578
7579 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

7594
7595 2000-10-04 Akim Demaille <akim@epita.fr>

7600
7601 * doc/bison.texinfo: Various typos spotted by Neil Booth.
7602
7603 2000-10-04 Akim Demaille <akim@epita.fr>
7604
7605 When a literal string is used to define two different tokens,
7606 `bison -v' segfaults.
7607 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
7608
7609 * tests/regression.m4: New file.
7610 Include the core of the sample provided by Piotr Gackiewicz.

7613
7614 2000-10-04 Akim Demaille <akim@epita.fr>
7615
7616 * src/reader.c (parse_expect_decl): Keep `count' within the size
7617 of `buffer'.
7618 From Neil Booth.
7619
7620 2000-10-02 Paul Eggert <eggert@twinsun.com>
7621
7622 * bison.s1 (yyparse): Assign the default value
7623 unconditionally, to avoid a GCC warning and make the parser a
7624 tad smaller.
7625
7626 2000-10-02 Akim Demaille <akim@epita.fr>
7627
7628 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
7629 options.
7630
7631 2000-10-02 Akim Demaille <akim@epita.fr>
7632
7633 * src/derives.c, src/print.c, src/reduce.c: To ease the
7634 translation, move some `\n' out of the translated strings.
7635
7636 2000-10-02 Akim Demaille <akim@epita.fr>
7637
7638 The location tracking mechanism is precious for parse error
7639 messages. Nevertheless, it is enabled only when `@n' is used in
7640 the grammar, which is a different issue (you can use it in error
7641 message, but not in the grammar per se). Therefore, there should
7642 be another means to enable it.
7643
7644 * src/getargs.c (getargs): Support `--locations'.
7645 (usage): Report it.
7646 * src/getargs.h (locationsflag): Export it.
7647 * src/lex.c (percent_table): Support `%locations'.
7648 * src/reader.c (yylsp_needed): Remove this variable, now replaced
7649 with `locationsflag'.
7650 * doc/bison.texinfo: Document `--locations' and `%locations'.
7651 Sort the options.
7652 * tests/calc.m4: Test it.
7653
7654 For regularity of the names, replace each
7655 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
7656 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
7657 In addition replace each `flag' with `_flag'.
7658
7659 2000-10-02 Akim Demaille <akim@epita.fr>
7660
7661 Also test parse error messages, including with YYERROR_VERBOSE.
7662
7663 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
7664 associative).
7665 Use it to check the computations.
7666 Use it to check `nonassoc' is honored.
7667 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
7668 `--yyerror-verbose'.
7669 (_AT_CHECK_CALC): Adjust to this option.
7670 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
7671
7672 2000-10-02 Akim Demaille <akim@epita.fr>
7673
7674 Test also `--verbose', `--defines' and `--name-prefix'. Testing
7675 the latter demonstrates a flaw in the handling of non debugging
7676 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7677 was used in order to simplify:
7678
7679 #if YYDEBUG
7680 if (yydebug)
7681 {
7682 ...
7683 }
7684 #endif
7685
7686 into
7687
7688 if (yydebug)
7689 {
7690 ...
7691 }
7692
7693 unfortunately this leads to a CPP conflict when
7694 `--name-prefix=foo' is used since it produces `#define yydebug
7695 foodebug'.
7696
7697 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7698 (YYDPRINTF): New macro.
7699 Spread its use.
7700 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7701 the bison options.
7702 Also test `--verbose', `--defines' and `--name-prefix'.
7703
7704 2000-10-02 Akim Demaille <akim@epita.fr>
7705
7706 Improve the readability of the produced parsers.
7707
7708 * src/bison.s1: Formatting changes.
7709 Improve the comment related to the `$' mark.
7710 (yydefault): Don't fall through to `yyresume': `goto' there.
7711 * src/output.c (output_parser): When the `$' is met, skip the end
7712 of its line.
7713 New variable, `number_of_dollar_signs', to check there's exactly
7714 one `$' in the parser skeleton.
7715
7716 2000-10-02 Akim Demaille <akim@epita.fr>
7717
7718 * lib/xstrdup.c: New file, from the fileutils.
7719 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
7720 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
7721 instead of strlen + xmalloc + strcpy.
7722 * src/symtab.c (copys): Remove, use xstrdup instead.
7723
7724 2000-10-02 Akim Demaille <akim@epita.fr>
7725
7726 * src/gram.h (associativity): New enum type which replaces the
7727 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
7728 `right_assoc', `left_assoc' and `non_assoc'.
7729 Adjust all dependencies.
7730 * src/reader.c: Formatting changes.
7731 (LTYPESTR): Don't define it, use it as a literal in
7732 `reader_output_yylsp'.
7733 * src/symtab.h (symbol_class): New enum type which replaces the
7734 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
7735 `sunknown', `stoken and `snterm'.
7736
7737 2000-10-02 Akim Demaille <akim@epita.fr>
7738
7739 * src/getargs.c (fixed_outfiles): Rename as...
7740 (yaccflag): for consistency and accuracy.
7741 Adjust dependencies.
7742
7743 2000-10-02 Akim Demaille <akim@epita.fr>
7744
7745 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
7746 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
7747 difficult and introduced a lot of core dump. It turns out that
7748 Bison used an implementation of `xmalloc' based on `calloc', and
7749 at various places it does depend upon the initialization to 0. I
7750 have not tried to isolate the pertinent places, and all the former
7751 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
7752 someone should address this issue.
7753
7754 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
7755 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
7756 files.

7762
7763 Various anti-`extern in *.c' changes.
7764
7765 * src/system.h: Include `assert.h'.
7766
7767 2000-10-02 Akim Demaille <akim@epita.fr>
7768
7769 * src/state.h (nstates, final_state, first_state, first_shift)
7770 (first_reduction): Move their exportation from here...
7771 * src/LR0.h: to here.
7772 Adjust dependencies.
7773 * src/getargs.c (statisticsflag): New variable.
7774 Add support for `--statistics'.
7775 Adjust dependencies.
7776
7777 Remove a lot of now useless `extern' statements in most files.
7778
7779 2000-10-02 Akim Demaille <akim@epita.fr>
7780
7781 * src/LR0.h: New file.

7792
7793 2000-10-02 Akim Demaille <akim@epita.fr>
7794
7795 * src/conflicts.c (conflict_report): New function.
7796 (conflict_log, verbose_conflict_log): Replace with...
7797 (print_conflicts): this function.
7798 Adjust dependencies.
7799 * src/conflicts.h: New file.
7800 Propagate its inclusion.
7801
7802 2000-10-02 Akim Demaille <akim@epita.fr>
7803

7841 2000-10-02 Akim Demaille <akim@epita.fr>

7850 YYDEFACT, that makes it possible for this function to use
7851 output_short_table.
7852
7853 2000-10-02 Akim Demaille <akim@epita.fr>
7854
7855 `user_toknums' is output as a `short[]' in `output.c', while it is
7856 defined as a `int[]' in `reader.c'. For consistency with the
7857 other output tables, `user_toknums' is now defined as a table of
7858 shorts.
7859
7860 * src/reader.c (user_toknums): Be a short table instead of an int
7861 table.
7862 Adjust dependencies.
7863
7864 Factor the short table outputs.
7865

7867 * src/output.c (output_gram, output_stos, output_rule_data)
7868 (output_base, output_table, output_check): Use it.
7869
7870 2000-10-02 Akim Demaille <akim@epita.fr>
7871
7872 * src/output.c (output): Topological sort of the functions, in
7873 order to get rid of the `static' prototypes.
7874 No longer use `register'.
7875 * src/output.h: New file.
7876 Propagate its inclusion in files explicitly prototyping functions
7877 from output.c.

7899 inclusion.
7900 Don't define PARAMS.
7901 * src/system.h: Define PARAMS.
7902 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
7903 purpose of config.h. system.h must not try to fix wrong
7904 definitions in config.h.
7905
7906 2000-09-20 Akim Demaille <akim@epita.fr>
7907

8069

8121
8122 Change the handling of @s so that they behave exactly like $s.
8123 There is now a pseudo variable @$ (readble and writable), location
8124 of the lhs of the rule (by default ranging from the location of
8125 the first symbol of the rhs, to the location of the last symbol,
8126 or, if the rhs is empty, YYLLOC).

8129 yyval.
8130 (yyparse): When providing a default semantic action, provide a

8152
8153 * src/output.c (output_rule_data): Output the documentation of

8161 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
8162 One `#if YYDEBUG' remains, since it uses variables which are
8163 defined only if `YYDEBUG != 0'.

8165 2000-03-16 Akim Demaille <akim@epita.fr>
8166

8203 * m4/Makefile.am (EXTRA_DIST): New variable.
8204 * m4/gettext.m4: New file, from the fileutils.

8889 way to specify the flags -n, -l, and -r. Also added hooks for
